5 tails wagging dogs a funny thing happened on the way to the form. in the past decade, many libraries believed they were developing or using automated systems to produce catalog cards, or order slips, or circulation control records. the trauma of aacr2 implementation has helped many to realize belatedly that they have, in fact, been building data bases. libraries must relate their own machine-readable records to each other in a new way as they face new applications. further methods of relating and using records from different libraries, and even different networks, are becoming necessities in our increasingly interdependent world. a narrow view of the process of creating records has often resulted in introduction of nonstandard practices that provide the required immediate result, but create garbage in the data base. in effect, letting the tails wag the dogs. for many years, john kountz and the tesla (technical standards for library automation) committee addressed this issue forcefully, but were as voices in the wilderness. the problems created are the problems of success. the expectations libraries have developed have outstripped their practices. many libraries are only now seriously addressing the practices they have used to create data bases that already contain hundreds of thousands of records. precisely because of its success, the oclc system is a useful case in point. in general, oclc has adhered closely to marc standards. in call number and holding fields, national standards have been late forthcoming, and libraries have often improvised. meeting the procrustean needs of catalog cards has ofttimes blinded libraries to the long-term effects of their practices. multiple subfield codes to force call number "stacking" and omission of periods from lc call numbers are two examples of card-driven practice. not following recommended oclc practice of fully updating the record at each use has created archive tapes requiring significant manual effort to properly reflect library holdings. variant branch cataloging practices create dilemmas. some malpractices have resulted from attempts to beat pricing algorithms . some, like retaining extraneous fields or accepting default options when they are incorrect, merely reflect laziness or shortsighted procedures. while implementing systems in the present, libraries must keep a weather eye to the future. what new requirements will future systems place on records being created today? brian aveney letter from the editor: a blank page letter from the editor a blank page kenneth j. varnum information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.12405 nothing is as daunting as a blank page, particularly now. as i sat down to write this issue’s letter, i was struck by how much fundamental uncertainty is in our lives, so much trauma. a blank page can emphasize our concerns that the old familiar should return at all, or that a new, better, normal will emerge. at the same time, a blank page can be liberating at a time when so much of our social, professional, and personal lives needs to be reconceptualized and reactivated in new, healthier , more respectful and inclusive ways. we are collectively faced with two important societal ailments. the first is the literal disease of the covid-19 pandemic that has been with us for only months. the other is the centuries-long festering disease of racial injustice, discrimination, and inequality that typifies (particularly, but not uniquely) american society. while some of us may be in better positions to help heal one or the other of these two ailments, we can all do something in both, as different as they are. lend emotional support to those in need of it, take part in rallies if your personal health and circumstances allow, and advocate for change to government officials at all levels from local to national. learn about the issues and explore ways you can make a difference on either or both fronts. i hope i am not being foolish or naive when i say i believe the blank page before us as a society will be liberating: an opportunity to shift ourselves toward a better, more equitable, more just path. * * * * * * to rephrase humphrey bogart’s rick blaine in casablanca, “it doesn’t take much to see that the problems of three little people library association divisions don’t amount to a hill of beans in this crazy world.” but despite the small global impact of our collective decision, i am glad our alcts, llama, and lita colleagues chose a united future as core: leadership, infrastructure, futures. watch for more information about what the merged division means for our three divisions and this journal in the months to come. sincerely, kenneth j. varnum,

technologies and libraries | march 2017 1 for a long time, i’ve have an idea that when a new president of the united states is elected, sometime after he's sworn in, amid all of the briefings, a wizened old man sits down with him to have the talk. in my imagination the messenger is some cross between the templar knight from indiana jones and the last crusade and the international express man from neil gaiman and terry pratchett’s good omens: officious yet wise. he tells the new president the why of it all, the real reasons why important things have happened in the ways they have, making all the decisions that seemed so wrong now seem inevitable. and probably not for the first time the new president thinks to himself “what have i gotten myself into?” this is clearly reflective of my desire for there to be, if not a reason for everything that happens, then at least some record of it all that can be reviewed, synthesized, and mined for meaning by future leaders. it’s the librarian in me i suppose. although being lita president bears absolutely no resemblance to being president of the united states, i have been thinking about this little imagining of mine a lot lately. this is probably because, now that i am midway through my presidential cycle (vice president, president, past president), i realize how much of what i’ve done has been marked by the absence of such a record. i did not receive a “how to be lita president” manual along with my gavel, and no one gave me the lita version of the talk. the one person who could have done it, lita executive director jenny levine, was as new to her position as i was to mine, so we have learned together and asked many questions of those around us with more experience. we are in the midst of election season, and will soon have a new president-elect. bohyun kim and david lee king are both excellent candidates (http://litablog.org/2017/01/meet-yourcandidates-for-the-2017-lita-election/); those of you who have not yet voted have a difficult choice. in order to make a little progress toward developing that how-to guide i thought i’d document a few of things i’ve learned since being lita president. being lita president also means being president of a division of the american library association. when i was elected i expected to manage the business of the library information technology association—board meetings, committee appointments, presidential programs and lita forums. seeing the board complete the lita strategic plan (http://www.ala.org/lita/about/strategic) was a great accomplishment at this level. while it’s possible for a division leader to have minimal interactions with “big ala” during their aimee fifarek (aimee.fifarek@phoenix.gov) is lita president 2016-17 and deputy director for customer support, it and digital initiatives at phoenix public library, phoenix, az. president’s message | fifarek https://doi.org/10.6017/ital.v36i1.9808 2 term and still be successful, my priority for my presidential year—increasing value litans receive from membership, especially those who are not able to attend in-person conferences—meant that i needed to learn more about how ala works. after a year and a half, i have a much better understanding of the association’s budgeting, publishing, and technology practices, and how all of these are impacted by declines in membership and decreasing revenues. future lita leaders are going to need to continue to be engaged at the larger organizational level if we are to be able to use lita’s technological knowledge and expertise to support ala’s efforts to maximize efficiency while minimizing costs. being lita president means speaking not just to, but for, an incredibly diverse community. my plan when i became lita president was to blog on a more regular basis. however, i didn’t expect some of my first communications to be about a mass shooting in dallas (in advance of the forum in ft. worth) or working with the board to craft a statement on inclusivity after the us presidential election. the proverbial curse “may you live in interesting times” has certainly been true this year. having to speak to the lita community about those issues made me acutely aware of my responsibility to adequately represent you when we’ve also been asked to weigh in on technology policy issues at the federal level such as the call for increased gun violence research and rescinding isp regulations on privacy protection. the decision by the board to include advocacy and information policy as a primary focus for the strategic plan was certainly prescient. we are fortunate that our president elect, andromeda yelton, is both well-versed in the issues and able to speak eloquently to them1. being lita president means being part of more than one team i’m continually amazed at the hard work and dedication that board members (http://www.ala.org/lita/about/board), committee and interest group chairs (http://www.ala.org/lita/about/committees/chairs), and anyone who fits into involvement our member persona (http://litablog.org/2017/03/who-are-lita-members-lita-personas/). the success of lita as an organization is entirely due to the time and passion of this team. but when you become lita president-elect you get a new team—the other division vice presidents. this cohort travels to ala hq in chicago in october after they are elected to meet each other and the incoming ala president and learn about the structure of ala. i have learned much from the other presidents this year, and we have had a number of truly productive discussions about how the divisions can collaborate and learn from each other to more effectively serve our members. lita is directly benefitting from the expertise of the other groups and they are in turn looking to us for both our technical skillset and the successes we’ve had over 50-years as an association. information technologies and libraries | march 1017 3 consider this a new preface to the how to be lita president manual. i hope that my successors find it useful, and that it will serve as an inspiration for any litans out there who are thinking about putting their name on the ballot in future years. it has been a marvelous and educational experience. and the gavel is pretty cool, too. references 1. making ala great again, publisher’s weekly, feb

ten commandments of interacting with nontechnical people m ore than ten years of working with technology and interacting with nontechnical users in a higher education environment has taught me many lessons about successful communication strategies. somehow, in that time, i have been fortunate to learn some effective mechanisms for providing constructive support and leading successful technical projects with both technically and “semitechnically” minded patrons and librarians. i have come to think of myself as someone who lives in the “in between,” existing more in the beyond than the bed or the bath, and, while not a native of either place, i like to think that i am someone who is comfortable in both the technical and traditional cliques within the library. ironically, it turns out that the most critical pieces to successfully implementing technology solutions and bridging the digital divide in libraries has been categorically nontechnical in nature; it all comes down to collegiality, clear communication, and a commitment to collaboration. as i ruminated on the last ten plus years of working in technology, i began to think of the behaviors and techniques that have proved most useful in developing successful relationships across all areas of the library. the result is this list of the top ten dos and don’ts for those of us self-identified techies who are working more and more often with the self-identified nontechnical set. 1. be inclusive—i have been around long enough to see how projects that include only technical people are doomed to scrutiny and criticism. the single best strategy i have found to getting buy-in for technical projects is to include key stakeholders and those with influence in project planning and core decision-making. not only does this create support for projects, but it encourages others to have a sense of ownership in project implementation—and when people feel ownership for a project, they are more likely to help it succeed. 2. share the knowledge—i don’t know if it is just the nature of librarianship, but librarians like to know things, and more often than not they have a healthy sense of curiosity about how things work. i find it goes a long way when i take a few moments to explain how a particular technology works. our public services specialists, in particular, often want to know the details of how our digital tools work so that they can teach users most effectively and answer questions users have about how they function. sharing expertise is a really nice way to be inclusive. 3. know when you have shared enough—in the same way that i don’t need to know every deep detail of collections management to appreciate it, most nontechies don’t need hour-long lectures on how each component of technology relates to the other. knowing how much information to share when describing concepts is critical to keeping people’s interest and generally keeping you approachable. 4. communicate in english—it is true that every specialization has its own vocabulary and acronyms (oh how we love acronyms in libraries) that have no relevance to nonspecialists. i especially see this in the jargon we use in the library to describe our tools and services. the best policy is to avoid jargon and explain concepts in lay-person’s terms or, if using jargon is unavoidable, define specialized words in the simplest terms possible. using analogies and drawing pictures can be excellent ways to describe technical concepts and how they work. it is amazing how much from kindergarten remains relevant later in life! 5. avoid techno-snobbery—i know that i am risking virtual ostracism in writing this, but i think it needs to be said. just because i understand technology does not make me better than others, and i have heard some variant of the “cup holder on the computer” joke way too often. even if you don’t make these kinds of comments in front of people who aren’t as technically capable as you, the attitude will be apparent in your interactions, and there is truly nothing more condescending. 6. meet people halfway—when people are trying to ask technology-related questions or converse about technical issues, don’t correct small mistakes. instead, try to understand and coax out their meaning; elaborate on what they are saying, and extend the conversation to include information they might not be aware of. people don’t like to be corrected or made to feel stupid—it is embarrassing. if their understanding is close enough to the basic idea, letting small mistakes in terminology slide can create an opening for a deeper understanding. you can provide the correct terminology when talking about the topic without making a point to correct people. 7. don’t make a clean technical/nontechnical distinction— after once offering the “technical” perspective on a topic, one librarian said to me that it wasn’t that they themselves didn’t have any technical mark dehmlow (mdehmlow@nd.edu) is digital initiatives librarian, hesburgh libraries, university of notre dame, notre dame, indiana. 54 information technology and libraries | june 2009 perspective, it just wasn’t perhaps as extensive as mine. each person has some level of technical expertise; it is better to encourage the development of that understanding rather than compartmentalizing people on the basis of their area of expertise. 8. don’t expect everyone to be interested—just because i chose a technical track and am interested in it doesn’t mean everyone should be. sometimes people just want to focus on their area of expertise and let the technical work be handled by the techies. 9. assume everyone is capable—at least at some level. sometimes it is just a question of describing concepts in the right way, and besides, not everyone should be a programmer. everyone brings their own skills to the table and that should be respected. 10. expertise is just that—and no one, no one knows everything. there just isn’t enough time, and our brains aren’t that big. embrace those with different expertise, and bring those perspectives into your project planning. a purely technical perspective, while perhaps being efficient, may not provide a practical or intuitive solution for users. diversity in perspective creates stronger projects. in the same way that the most interesting work in academia is becoming increasingly more multidisciplinary, so too the most successful work in libraries needs to bring diverse perspectives to the fore. while it is easy to say libraries are constantly becoming more technically oriented because of the expanse of digital collections and services, the need for the convergence of the technical and traditional domains is clear—digital preservation is a good example of an area that requires the lessons and strengths learned from physical preservation, and, if anything, the technical aspects still raise more questions than solutions—just see henry newman’s article “rocks don’t need to be backed up” to see what i mean.1 increasingly, as we develop and implement applications that better leverage our collections and highlight our services, their success hinges on their usability, user-driven design, and implementations based on user feedback. these “user”-based evaluation techniques fit more closely with traditional aspects of public services: interacting with patrons. lastly, it is also important to remember that technology can be intimidating. it has already caused a good deal of anxiety for those in libraries who are worried about long-term job security as technology continues to initiate changes in the way we perform our jobs. one of the best ways to bring people along is to demystify the scary parts of technology and help them see a role for themselves in the future of the library. going back to maslow’s hierarchy of needs, people want to feel a sense of security and belonging, and i believe it is incumbent upon those of us with a deep understanding of technology to help bring the technical to the traditional in a way that serves everyone in the process. reference 1. henry newman, “rocks don’t need to be backed up,” enterprise

webscale discovery mark dehmlow information technology and libraries | june 2013 1 early implementations of discovery systems were revolutionary in their ability to bring together metadata from masses of scholarly resources into super indexes but they were also somewhat unsophisticated in that their initial focus was primarily on the aggregation of data. the data is critical, but the debates over vendors' unwillingness to share data have overshadowed other important features and functionality that are important to making discovery systems valuable, especially in the areas of getting users the actual resources that they find, delivering the most relevant results, and being more aware of the full user context not merely their search query. the user context is a multidimensional matrix encompassing: (1) level of experience, (2) comprehensiveness of their research need, (3) type of scholarly materials the user primarily works with, (4) user discipline, and also (5) what physical or virtual location the user is performing their research from. missing services and opportunities a major issue that continues to confound me is the lack of fully integrated request and delivery services that many discovery systems lack. of course, all of them implement full text linking to every online article that they can create a link to, but as the sphere of scholarly data stretches beyond just articles, library print collections and delivery services have continued to be neglected primarily because implementing those services in an intuitively integrated way, beyond the "link to your old opac" methodology, remains a complex task. my main concern with this deficit is that there is a significant amount of scholarly material only available in print and to focus primarily on electronic access limits the ability of our users to perform comprehensive research and reduces access to significant resources and services that libraries provide. during the transition from print to online, we need to consider user behaviors and preferences while ebook technology becomes more user-friendly, especially for academic materials which are often difficult to access and use because of clunky digital rights management and distribution models. the most recent ithaka study on faculty research behaviors noted that 80% of faculty respondents still find it much or somewhat easier to read an entire book in print versus in electronic format.1 this will change over time as the technology evolves, but it will be quite some time before all written works are available online and researchers often needs access to the long tail of unique resources that support very narrow and niche knowledge areas. mark dehmlow (mdehmlow@nd.edu), a member of lita and the ital editorial board, is the director, information technology program, hesburgh libraries, university of notre dame, south bend, indiana. editorial board thoughts: services and user context in the era of webscale discovery | dehmlow 2 some of the discovery systems have integrated the dlf recommended interoperability standards seamlessly2 into their interfaces, but some don't provide much more than a link back to the libraries’ traditional opac interface, often in a completely different user interface that requires the user to make a cognitive shift. and even those vendors who do integrate basic ils functionality don't intuitively integrate other important library services such as localized delivery or interlibrary loan services. for many of our users, particularly faculty and graduate students, their goal is to exhaustively evaluate every useful resource in the pursuit of their research, not only the easiest and quickest to access. in addition to these deficits also lies untapped opportunity. the aggregation of so much bibliographic data in these systems could allow for providers to build more intuitive connections between primary resources and bibliographic records that relate to those resources. one of our librarians recently commented that it would be really valuable if we could connect all of the book reviews in the webscale index to the actual bibliographic record for the book placing the related information for the book at the primary point of access for the user. another librarian commented on how valuable it would be to integrate user generated comments about books from worldcat.org in a similar way. i believe one of the next major opportunities for discovery systems is to begin building holistic connections between the objects in their indexes, perhaps using linked data techniques. relevancy refactored determining actual relevancy of an item to a user query is a much more nuanced business than standard term frequency — inverse document frequency (td-idf). even when used in concert with field weighting for metadata like author and title, this type of algorithm has mixed effectiveness because while math can easily indicate how often a series of words occur in a document, it requires considering the whole user context to best derive what a user is looking for. perhaps one of the more interesting developments in relevancy enhancements is the incorporation of social and usage analytics. this more intricate adjustment to relevancy calculation is what makes google so powerful — they can take how often a website is referenced in other websites and how often users go to a website to impact a website’s relevancy to a user query. ex libris is currently using similar strategies with something they call scholar rank. they enhance their document relevancy through using their bx recommender service (a “users who downloaded this article also down loaded these articles” – style service that is based on link resolver log analysis) and data like impact factor.3 the physical and virtual location of a user provides another unique context that doesn’t get much attention. recently, we made our default search box the library catalog for searches performed in our stacks, the idea being that a user is most likely looking for things in our collection if they are in the tower. they can easily jump to the webscale search if they like by clicking an adjacent tab. another specialized context is for our users are our subject pages, which have lists of library resources that relate to specific disciplinary areas. where possible, each of these pages features a information technology and libraries | june 2013 3 subject quicksearch box which currently utilizes metasearch to provide discipline scoped results. we would like to eventually replace these popular metasearches with the benefits of a webscale search, but scoped by. serials solutions’ summon is able to provide through its “discipline-scoped search” feature.4 conclusion libraries are still struggling with how to market and position these massive indexes in the context of their websites and the other services they provide. in part, discovery systems induce discomfort for library professionals because the ways in which relevancy is calculated are becoming more opaque. in the face of all this ambiguity, i still believe that these systems are incredibly useful and valuable for support of different research needs at different levels – getting novice users quick access to a handful of scholarly resources and augmenting the deep research process of our expert users. many of these systems on the market are evolving into more complex search tools, but there is a lot of room for these systems to grow as well. if you were to take the best of each of the systems and put them together, you might actually be on your way to having a complete solution. for libraries as we continue to license products and implement these solutions, it is important to develop a more complex understanding of what our users need and then ensure our discovery systems will translate their simple keyword query into results they are actually looking for and then help them easily request the materials that turn up in those results. references 1. ross housewright, roger c. schonfeld, and kate wulfson, ithaka s+r us faculty survey 2012.

http://www.serialssolutions.com/en/services/summon/features-functionality/search editorial | truitt 107 marc truitteditorial: computing in the “cloud” silver lining or stormy weather ahead? c loud computing. remote hosting. software as a service (saas). outsourcing. terms that all describe various parts of the same it elephant these days. the sexy ones—cloud computing, for example—emphasize new age-y, “2.0” virtues of collaboration and sharing with perhaps slightly mystic overtones: exactly where and what is the “cloud,” after all? others, such as the more utilitarian “remote hosting” and “outsourcing,” appeal more to the bean counters and sustainabilityminded among us. but they’re really all about the same thing: the tradeoff between cost and control. that the issue increasingly resonates with it operations at all levels these days can be seen in various ways. i’ll cite just a few: n at the meeting of the lita heads of library technology (holt) interest group at the 2009 ala annual conference in chicago, two topics dominated the list of proposed holt programs for the 2010 annual conference. one of these was the question of virtualization technology, and the other was the whole white hat–black hat dichotomy of the cloud.1 practically everyone in the room seemed to be looking at—or wanting to know more about—the cloud and how it might be used to benefit institutions. n my institution is considering outsourcing e-mail. all of it—to google. times are tough, and we’re being told that by handing e-mail over to the googleplex, our hardware, licensing, evergreening, and technical support fees will total zero. zilch. with no advertising. heady stuff when your campus hosts thirty-plus central and departmental mail servers, at least as many blackberry servers, and total costs in people, hardware, licensing, and infrastructure are estimated to exceed can$1,000,000 annually. n in the last couple of days, library electronic discussion lists such as web4lib have been abuzz— or do we now say a-twitter?—about amazon’s orwellian kindle episode, in which the firm deleted copies of 1984 and animal farm from subscribers’ kindle e-book readers without their knowledge or consent.2 indeed, amazon’s action was in violation of its own terms of service, in which the company “grants [the kindle owner] the non-exclusive right to keep a permanent copy of the applicable digital content and to view, use, and display such digital content an unlimited number of times, solely on the device or as authorized by amazon as part of the service and solely for [the kindle owner ’s] personal, noncommercial use.”3 all of this has me thinking back to the late 1990s marketing slogan of a manufacturer of consumer-grade mass storage devices—remember removable hard drives? iomega launched its advertising campaign for the 1 gb jaz drive with the catch-line “because it’s your stuff.” ultimately, whether we park it locally or send it to the cloud, i think we need to remember that it is our stuff. what i fear is that in straitened times, it becomes easy to forget this as we struggle to balance limited staff, infrastructure, and budgets. we wonder how we’ll find the time and resources to do all the sexy and forward-looking things, burdened as we are with the demands of supporting legacy applications, “utility” services, and a huge and constantly growing pile of all kinds of content that must be stored, served up, backed up (and, we hope, not too often, restored), migrated, and preserved. the buzz over the cloud and all its variants thus has a certain siren-like quality about it. the notion of signing over to someone else’s care—for little or no apparent cost—our basic services and even our own content (our stuff) is very appealing. the song is all the more persuasive in a climate where we’ve moved from just the normal bad news of merely doing more with less to a situation where staff layoffs are no longer limited to corporate and public libraries, but indeed extend now to our greatest institutions.4 at the risk of sounding like a paranoid naysayer to what might seem a no-brainer proposition, i’d like to suggest a few test questions for evaluating whether, how, and when we send our stuff into the cloud: 1. why are we doing this? what do we hope to gain? 2. what will it cost us? bear in mind that nothing is free—except, in the open-source community, where free beer is, unlike kittens, free. if, for example, the borg offer to provide institutional mail without advertisements, there is surely a cost somewhere. the borg, sensibly enough, are not in business to provide us with pro bono services. 3. what is the gain or loss to our staff and patrons in terms of local customization options, functionality, access, etc? 4. how much control do we have over the service offered or how our content is used, stored, marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 108 information technology and libraries | september 2009 repurposed, or made available to other parties? 5. what’s the exit strategy? what if we want to pick up and move elsewhere? can we reclaim all of our stuff easily and portably, leaving no sign that we’d ever sent it to the cloud? we are responsible for the services we provide and for the content we have been entrusted. we cannot shrug off this duty by simply consigning our services and our stuff to the cloud. to do so leaves us vulnerable to an irreparable loss of credibility with our users; eventually some among them would rightly ask, “so what is it that you folks do, anyway?” we’re responsible for it—whether it’s at home or in the cloud—because it’s our stuff. it is our stuff, right? references and notes 1. i should confess, in the interest of full disclosure, that it was eli neiburger of the ann arbor district library who suggested “hosted services as savior or slippery slope” for next year’s holt program. i’ve shamelessly filched eli’s topic, if not his catchy title, for this column. thanks, eli. also, again in the interest of full disclosure, i suggested the virtualization topic, which eventually won the support of the group. finally, some participants in the discussion observed that virtualization technology and hosting are in many ways two sides of the same topical coin, but i’ll leave that for others to debate. 2. brad stone, “amazon erases orwell books from kindle,” new york times, july 17, 2009,

library of philadelphia. © 2021. “public libraries leading the way” is a regular column spotlighting technology in public libraries. in the early weeks of the pandemic, the special collections division of the free library of philadelphia (https://freelibrary.org/) responded to the library’s call for fun and interactive online engagement. initially staff members released games and buzzfeed-inspired lists via various social media accounts to amuse patrons, distract from the lockdown, and provide educational programming. as the list of activities grew, we realized this content needed a more substantial home; the return on investment of time for the development and production of an online game to be released once on social media was not sufficient. activities and passive programming that took hours to create could easily fall victim to social media’s algorithms and be quickly buried in a patron’s feed. the free library’s official blog was an insufficient option because it promoted all library programming, and our goal was to highlight the value of our division and the materials housed within it. we resolved these issues by creating an online repository solely with freeware systems (https://bit.ly/funwithflpspeccoll). the repository provides a stable landing page wherein the special collections division content builds meaningful connections with patrons of all ages. this model can be readily adapted and is a valuable tool for library workers promoting their own online engagement. repository framework it was clear that our division could not add to the burden of an overworked it staff by requesting support for digital engagement. we needed to seek external alternatives that would interest patrons and could be managed with limited training. before we began our search, we brainstormed a list of requirements: • an inexpensive and user-friendly hosting platform • a pleasing look and easy navigation • the ability to be updated frequently and easily • the flexibility to adapt and expand as our requirements change our search led us to the google suite of products, specifically google sites and google drawings. google sites and google drawings integrated perfectly with each other, and we appreciated their usability and relative simplicity. once we selected the software, we knew we needed a list of best practices to guide the repository’s creation: ● to establish a visual connection with our official website, the repository would primarily use the free library’s branded color scheme. ● all thumbnails created would be square, allowing us to reuse the image as promotional material on different social media accounts. mailto:sunik@freelibrary.org mailto:brownc@freelibrary.org https://freelibrary.org/ https://bit.ly/funwithflpspeccoll information technology and libraries march 2021 we can do it for free! | suni and brown 2 ● all members of the division can create content, but the ability to update and edit the repository would remain limited to ensure consistency. these guidelines have proven effective. the color scheme and thumbnail rules formed a framework wherein we could work productively without “reinventing the wheel.” limiting administrative abilities has allowed us to maintain a controlled vocabulary within the repository, better unifying the content. repository software the google suite, specifically google sites, is advantageous for library workers looking to create professional-looking content quickly. it is free with a google account and built-in templates allow users to build a fully functional website within a few hours with little-to-no design experience. as with all freeware, google sites has quirks. the foremost is that while there are options for customization, these options are finite. there are a limited number of layout, header, and font designs meaning that anyone using the software must temper their vision to fit within the confines of the program. google drawings is far more flexible, in part because it is a much simpler program. users familiar with software like powerpoint or ms paint have the ability to design images for headers, thumbnails, etc. two drawbacks we encountered with this freeware are the restrictions on image upload size (a consideration for our division given the archival files used in our digital collections) and the limited ability to create word art. for our division, the advantages of these software products outweigh their limitations. content framework the repository houses programming devised primarily with freeware. an early discovery was a suite of activities from flippity (https://www.flippity.net). designed for educational use, flippity provides templates for a variety of online activities including memory games, matching games, and board games. our primary focus has been on the first two, although we continue to explore new aspects of this suite as templates are added. flippity works with google sheets and can integrate images from google drawings. jigsaw planet (https://jigsawplanet.net/) has been used extensively by libraries and museums during the pandemic. it allows creators to easily turn images into puzzles that are played online, either on the site itself or through embedding the puzzle. the site allows registered users to access leaderboards, and it allows creators to track how many times puzzles have been played. in addition to the ease of use, the major benefit of jigsaw planet is that the patron can customize their experience by changing the number of pieces to fit their preferred level of difficulty. the desire for audio and video content has surged over the last several months, and we have sought to meet that need through the use of a variety of software. in regard to video, youtube is not a new tool, but the majority of our pre-pandemic programs were not filmed. with the shift to crowdcast and zoom, we now have a library of online lectures and other events that have been uploaded to youtube and can be viewed repeatedly and at any time. with a dedicated home for this content, we have been inspired to seek out older videos of special collections programming across multiple channels and link them to the repository. https://www.flippity.net/ https://jigsawplanet.net/ information technology and libraries march 2021 we can do it for free! | suni and brown 3 one of the newest additions to our offerings has been the podcast story search from special collections (http://bit.ly/flpstorysearch), which explores stories based on, inspired by, or connected to material artifacts. the podcast is recorded and edited using zencastr and audacity and is posted on anchor, which also distributes it to major listening apps. in recent weeks, our division has added images, blog posts, and additional con tent for current and past exhibitions. this is the first formal exhibition compilation since the special collections division began in 2015, and we are delighted that it is available for the public to explore. the material is arranged using templates and tools available in google sites, allowing patrons to view image carousels, exhibition tags, and past programs. the inclusion of this material marks a shift away from the repository functioning as a response to the need for pandemic-related content to a living history of our division and our work promoting the special collections of the free library. accessibility accessibility and equity of access lie at the core of library service. sadly, we were not initially focused on this point, and our content was not fully accessible, e.g., text was presented in thumbnails only which limited the use of screen readers to relay information. as the content expanded, we sought to make the space as inclusive as the freeware limits allowed. alternative text was added to images and information was not limited within thumbnails. this is an ongoing process, but one that is necessary to reach as many patrons as possible. analytics site visits and other statistics for a library’s online presence are always important, but especially so during the pandemic when restricted physical access has driven more patrons to online resources. our plan for capturing this information was two-pronged. first, we used bit.ly to create customized, trackable links for our content. these are used within the repository and on social media and in other online promotions. this has proven to increase repository traffic while providing information on how patrons discover our content. the statistics generated from bit.ly are only available for 30 days for free accounts, albeit in a rolling 30-day window. knowing this, we transcribe the statistics monthly into a spreadsheet to maintain a consistent account of patron access. our second prong is google analytics, a freeware option that only tracks data within the repository. google analytics connects a single google account to google sites, but the integration is seamless and the data remains available indefinitely. this provides a visual breakdown of statistics, including maps and graphs that are easily shared with other stakeholders. by using both tools we are able to surmise who is visiting the repository, where they are finding the links, and which sections are popular with our patrons. conclusion the special collections repository was created in response to a growing need for online patron engagement during the early weeks of the pandemic. our division strove to engage the public with fun, educational programming and activities primarily using freeware. this has proven to be successful with the general public and members of our division. the statistics from the site have both informed content creation and engendered a better appreciation for the repository from our administration. as we move forward, the repository is evolving into a comprehensive collection of what the special collection division does and how we meet the need for patron engagement http://bit.ly/flpstorysearch information technology and libraries march 2021 we can do it for free! | suni and brown 4 online and in person. it is a framework that can be used by library workers across a multitude of areas and specialties, housing activities from story times and passive programming to book clubs and lectures. repository framework repository software

the center for the study of southern culture, the atlanta history center, and the georgia music hall of fame, received an institute of museum and library services grant to develop a new model for library-museum-archives collaboration. this collaboration will broaden access to resources for learning communities through the use of the open archives initiative protocol for metadata harvesting (oaipmh). the project, titled music of social change (mosc), will use oai-pmh as a tool to bridge the widely varying metadata standards and practices across museums, archives, and libraries. this paper will focus specifically on the unique advantages of the use of oaipmh to concurrently maximize the exposure of metadata emergent from varying metadata cultures. t he metascholar initiative of emory university libraries, in collaboration with the center for the study of southern culture, the atlanta history center, and the georgia music hall of fame, received an institute of museum and library services grant to develop a new model for library-museum-archives collaboration to broaden access to resources for learning communities through the use of the open archives initiative protocol for metadata harvesting (oai-pmh).1 the collaborators of the project, entitled music of social change (mosc), are creating a subject-based virtual collection concerning music and musicians associated with social-change movements such as the civil-rights struggle. this paper will specifically focus on the advantages offered by oai-pmh in amalgamating and serving metadata from these institutional sources that are significantly different in kind.2 there has been a great deal of discussion within the library community as to the possibilities oai-pmh holds for harvesting, aggregating, and then disseminating research metadata. however, in reality, only a few of institutions (be they museum, archives, or libraries) have actually begun to utilize oai-pmh to this end. there are some practical, historical barriers to implementing any shared system for distributing metadata across institutions that are, more than in degree, different in kind. one of these significant differences is of metadata cultures and practices. libraries have traditionally incrementally assigned metadata at an item level within their collection(s). the strength of this model is that at least a minimal amount of metadata is assigned to a very high percentage of items within the collection. the challenge of such a system is that for such metadata records to interoperate within a shared database and through a common interface (for example, the traditional union catalog), the metadata fields have been quite rigidly defined compared to those within archival and museum environments. due to tradition as well as the sheer volume of items collected by libraries, metadata at an item level are not greatly detailed or contextualized. often, items within library collections lack robust relationary mapping to other items within or outside of the collection, as is done, for example, in archival processing. content contextualization is highly valued by archival metadata practices and culture as the central tenet of metadata creation. items at a subcollection level almost always have metadata derivative from and deferential to that of the collection-level metadata. the great benefit of archival practices in metadata assignment is a contextualization of content that reflects the background, the topographic place in time and space of a given portion of a collection and its organic, emergent relationship to the whole. the weaknesses of this model are a great inconsistency in description details and variables (at the collection and subcollection levels), as well as very disparate levels of granularity within the hierarchy of the structure of a collection at which metadata are assigned. such disparities among institutional types feed an unnecessary level of misunderstanding by libraries of the metadata culture and aims of archives as well as those of museums. museums often have very skeletal documented (as opposed to undocumented) metadata about their collections or objects therein. often museums are not funded to make metadata on their collections freely available. it is common, in fact, for curatorial staff to view metadata as intellectual property to which they serve as gatekeepers, reflecting a professional value placed upon contextualizing materials for users. this is done on a user-by-user or exhibition-by-exhibition basis, depending on user background or the thesis of a given exhibition. additionally, museums perceive information on the aboutness of their collections to be a class of capital with which they can always potentially cost-recover or generate income. within the culture of museums, staff have traditionally been disinclined to make their collections available in an unmediated manner. additionally, there has been resistance to documenting information about collections in a systematic way. there is even greater resistance to adhering to any prescriptions on metadata as would be required for compliance with even the most minimally structured database. such regulation would discriminate the mosc project: using the oai-pmh to bridge metadata cultural differences across museums, archives, and libraries eulalia roel eulalia roel (eulalia.roel@gmail.com) is coordinator of information resources at the federal reserve, atlanta. against the nuanced information required for each and every object within a collection. � why oai-pmh to bridge these cultures? oai-pmh was selected by the mosc project as a means to bridge some of these substantial disparities. the protocol is often mistakenly assumed to function only with metadata expressed as unqualified dublin core (dc). in fact, the protocol functions with any metadata format expressed by extensible markup language (xml); this is the minimal requirement for content to serve metadata through oai-pmh. this includes those formats that have been well received by institutions other than libraries, such as xml encoded archival description (ead) as it is used in archives. as per 4.2 of the oai-pmh guidelines for repository implementers, communities are able to develop their own collection description xml schemas for use within description . . . elements. if all that is desired is the ability to include an unstructured textual description, then it is recommended that repositories use the dublin core description element. seven existing schemes are: dublin core, encoded archival description (ead), the eprints schema, rslp collection description schema, uddi/wsdl, marc21, and the branding schema.3 the oai protocol has often been partnered with unqualified dc metadata, as this is the most minimal metadata structure necessary for participation in an oai harvesting system. not only are these dc fields unqualified, no fields are actually required. no structure or regulations are codified outside of requiring metadata contributors to adhere to this unqualified metadata schema. therefore, the oai protocol requires minimal technology support and resources at any given contributing site (such support varying more widely across institutions than even their metadata practices themselves). this maximizes flexibility in metadata contribution, as well as maximizing interoperability between the collective data pool from which a user can search. granted, this unregulated framework does come at a cost of inconsistency in metadata detail and quality. however, the great advantage of such nominal requirements is that they enable contributors with minimal metadata-encoding practices to participate in the metadata collaborative. following is an example of a record as it may appear in the mosc collection: <record> <header> <identifier>oai:atlantahistorycenter.com:10 </identifier> <datestamp>2003-03-31</datestamp> <setspec>south:blues</setspec> <setspec>south:mississippi-delta-region </setspec> </header> <metadata> <oai_dc:dc xmlns:oai_dc=”http://www.openarchives.org/oai/ oai_dc/” xmlns:dc=”http://purl.org/dc/elements/1.1/” xmlns:xsi=”http://www.w3.org/2001/ xmlschema-instance” xsi:schemalocation=”http://www.openarchives.org/ oai/2.0/oai_dc/http://www.openarchives.org/ oai/2.0/oai_dc.xsd”> <dc:title>long hall recordings</dc:title> <dc:creator>morris, william</dc:creator> <dc:subject>blues</dc:subject> <dc:description>..</dc:description> <dc:description>comment: sound amateur recording </dc:description> <dc:date>2003-05-16</dc:date> <dc:type>sound recording</dc:type> <dc:identifier>http://atlantahistorycenter.com/ porcelain/10</dc:identifier> </oai_dc:dc> </metadata> </record> additionally, with no fields required by the dc schema, institutions can have absolute discretion as to what metadata are exposed if this is a concern (as may be for privacy considerations for archives or for intellectualproperty concerns for museums). however, one of the great strengths of implementing oai-pmh is that, while the threshold for regulating metadata is low, the protocol can also handle any metadata format expressed by xml, including data formats significantly more structured than dc; for example, ead, text encoding initiative (tei), and tei lite-defined documents. scholars are then able to access these scholarly objects via one point, while still being able to collectively access and utilize all metadata objects available in all collections, from the most to the least robust. the aim of the mosc project participants in selecting oai-pmh is to maximize participation from fairly disparate kinds of organizations, with equally disparate kinds of metadata cultures and practices. in comparison to other, currently available methods of metadata aggregation, oai-pmh is maximally forgiving of discordant metadata suppliers. thereby, the hope is, metadata contributions are maximized. concurrently, the protocol the mosc project | roel 23 24 information technology and libraries | march 2005 allows for highly robust metadata formats. as the cost for inclusion in aggregated systems, in some cases metadata objects are stripped down. this need is eliminated when oai-pmh is utilized. the use of the protocol allows for the inclusion of objects consisting of the most skeletal unqualified dublin core elements, while still accommodating the most complicated metadata objects. optimally, this is a means to achieve a critical mass of contributed resources that will enable end users to utilize the mosc project as the premier site and a primary resource for information on materials about music and musicians associated with social-change movements. � acknowledgment the author would like to express her sincerest gratitude to the institute of museum and library services for funding the music of social change project. references 1.

(marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. marc truitt editorial: and now for something (completely) different t he issue of ital you hold in your hands—be that issue physical or virtual; we won’t even go into the question of your hands!—represents something new for us. for a number of years, ex libris (and previously, endeavor information systems) has generously sponsored the lita/ex libris (née lita/endeavor) student writing award competition. the competition seeks manuscript submissions from enrolled lis students in the areas of ital’s publishing interests; a lita committee on which the editor of ital serves as an ex-officio member evaluates the entries and names a winner. traditionally, the winning essay has appeared in the pages of ital. in recent years, perhaps mirroring the waning interest in publication in traditional peerreviewed venues, the number of entrants in the competition has declined. in 2008, for instance, there were but nine submissions, and to get those, we had to extend the deadline six weeks from the end of february to midapril. in previous years, as i understand it, there often were even fewer. this year, without moving the goalposts, we had— hold onto your hats!—twenty-seven entries. of these, the review committee identified six finalists for discussion. the turnout was so good, in fact, that with the agreement of the committee, we at ital proposed to publish not only the winning paper but the other finalist entries as well. we hope that you will find them as stimulating as have we. even more importantly, we hope that by publishing such a large group of papers representing 2009’s best in technology-focused lis work, we will encourage similarly large numbers of quality submissions in the years to come. i would like to offer sincere thanks to my university of alberta colleague sandra shores, who as guest editor for this issue worked tirelessly over the past few months to shepherd quality student papers into substantial and interesting contributions to the literature. she and managing editor judith carter—who guest-edited our recent discovery issue—have both done fabulous jobs with their respective ital special issues. bravo! n ex libris’ sponsorship in one of those ironic twists that one more customarily associates with movie plots than with real life, the lita/ex libris student writing award recently almost lost its sponsor. at very nearly the same time that sandra was completing the preparation of the manuscripts for submission to ala production services (where they are copyedited and typeset), we learned that ex libris had notified lita that it had “decided to cease sponsoring” the student writing award. a brief round of e-mails among principals at lita, ex libris, and ital ensued, with the outcome being that carl grant, president of ex libris north america, graciously agreed to continue sponsorship for another year and reevaluate underwriting the award for the future. we at ital and i personally are grateful. carl’s message about the sponsorship raises some interesting issues on which i think we should reflect. his first point goes like this: it simply is not realistic for libraries to continue to believe that vendors have cash to fund these things at the same levels when libraries don’t have cash to buy things (or want to delay purchases or buy the product for greatly reduced amounts) from those same vendors. please understand the two are tied together. point taken and conceded. money is tight. carl’s argument, i think, speaks as well to a larger, implied question. libraries and library vendors share highly synergistic and, in recent years, increasingly antagonistic relationships. library vendors—and i think library system vendors in particular—come in for much vitriol and precious little appreciation from those of us on the customer side. we all think they charge too much (and by implication, must also make too much), that their support and service are frequently unresponsive to our needs, and that their systems are overly large, cumbersome, and usually don’t do things the way we want them done. at the same time, we forget that they are catering to the needs and whims of a small, highly specialized market that is characterized by numerous demands, a high degree of complexity, and whose members—“standards” notwithstanding—rarely perform the same task the same way across institutions. we expect very individualized service and support, but at the same time are penny-pinching misers in our ability and willingness to pay for these services. we are beggars, yet we insist on our right to be choosers. finally, at least for those of us of a certain generation—and yep, i count myself among its members—we chose librarianship for very specific reasons, which often means we are more than a little uneasy with concepts of “profit” and “bottom line” as applied to our world. we fail to understand the open-source dictum that “free as in kittens and not as in beer” means that we will have to pay someone for these services—it’s only a question of whom we will pay. carl continues, making another point: i do appreciate that you’re trying to provide us more recognition as part of this. frankly, that was another consideration in our thought of dropping it—we just didn’t feel like we were getting much for it. marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 4 information technology and libraries | march 2010 i’ve said before and i’ll say again, i’ve never, in all my years in this business had a single librarian say to me that because we sponsored this or that, it was even a consideration in their decision to buy something from us. not once, ever. companies like ours live on sales and service income. i want to encourage you to help make librarians aware that if they do appreciate when we do these things, it sure would be nice if they’d let us know in some real tangible ways that show that is true. . . . good will does not pay bills or salaries unless that good will translates into purchases of products and services (and please note, i’m not just speaking for ex libris here, i’m saying this for all vendors). and here is where carl’s and my views may begin to diverge. let’s start by drawing a distinction between vendor tchotchkes and vendor sponsorship. in fairness, carl didn’t say anything about tchotchkes, so why am i? i do so because i think that we need to bear in mind that there are multiple ways vendors seek to advertise themselves and their services to us, and geegaws are one such. trinkets are nice—i have yet to find a better gel pen than the ones given out at iug 14 (would that i could get more!)—but other than reminding me of a vendor’s name, they serve little useful purpose. the latter, vendor sponsorship, is something very different, very special, and not readily totaled on the bottom line. carl is quite right that sponsorship of the student writing award will not in and of itself cause me to buy aleph, primo, or sfx (oh right, i have that last one already!). these are products whose purchase is the result of lengthy and complex reviews that include highly detailed and painstaking needs analysis, specifications, rfps, site visits, demonstrations, and so on. due diligence to our parent institutions and obligations to our users require that we search for a balance among best-of-breed solutions, top-notch support, and fair pricing. those things aren’t related to sponsorship. what is related to sponsorship, though, is a sense of shared values and interests. of “doing the right thing.” i may or may not buy carl’s products because of the considerations above (and yes, ex libris fields very strong contenders in all areas of library automation); i definitely will, though, be more likely to think favorably of ex libris as a company that has similar—though not necessarily identical—values to mine, if it is obvious that it encourages and materially supports professional activities that i think are important. support for professional growth and scholarly publication in our field are two such values. i’m sure we can all name examples of this sort of behavior: in addition to support of the student writing award, ex libris’ long-standing prominence in the national information standards organization (niso) comes to mind. so too does the founding and ongoing support by innovative interfaces and the library consulting firm r2 for the taiga forum (http://www.taigaforum.org/), a group of academic associate university librarians. to the degree that i believe ex libris or another firm shares my values by supporting such activities—that it “does the right thing”—i will be just a bit more inclined to think positively of it when i’m casting about for solutions to a technology or other need faced by my institution. i will think of that firm as kin, if you will. with that, i will end this by again thanking carl and ex libris—because we don’t say thank you often enough!—for their generous support of the lita/ex libris student writing award. i hope that it will continue for a long time to come. that support is something about which i do care deeply. if you feel similarly—be it about the student writing award, niso, taiga, or whatever—i urge you to say so by sending an appropriate e-mail to your vendor’s representative or by simply saying thanks in person to the company’s head honcho on the ala exhibit floor. and the next time you are neck-deep in seemingly identical vendor quotations and need a way to figure out how to decide between them, remember the importance of shared values. n dan marmion longtime lita members and ital readers in particular will recognize the name of dan marmion, editor of this journal from 1999 through 2004. many current and recent members of the ital editorial board—including managing editor judith carter, webmaster andy boze, board member mark dehmlow, and i—can trace our involvement with ital to dan’s enthusiastic period of stewardship as editor. in addition to his leadership of ital, dan has been a mentor, colleague, boss, and friend. his service philosophy is best summarized in the words of a simple epigram that for many years has graced the wall behind the desk in his office: “it’s all about access!!” because of health issues, and in order to devote more time to his wife diana, daughter jennifer, and granddaughter madelyn, dan recently decided to retire from his position as associate director for information systems and digital access at the university of notre dame hesburgh libraries. he also will pursue his personal interests, which include organizing and listening to his extensive collection of jazz recordings, listening to books on cd, and following the exploits of his favorite sports teams, the football irish of notre dame, the indianapolis colts, and the new york yankees. we want to express our deep gratitude for all he has given to the profession, to lita, to ital, and to each of us personally over many years. we wish him all the best as he embarks on this new phase of his life. 240 i ournal of library automation vol. 7 i 3 september 197 4 book reviews case studies in lihm1·y computer systems, by richard phillips palmer. new york: r. r. bowker, 1973. 214p. $10.95. surely one of the most annoying and disappointing aspects of the literature of library automation is the complete lack of uniformity or standards for reports of individual accomplishments. thus one reads the continuing stream of reports of automated processes in individual libraries with only the remotest idea of which of the projects described are actually operating, which are in the process of being implemented, and which are merely proposals that still exist exclusively in the minds of their creators. in this volume, richard palmer has brought together a number of descriptions of operating systems, upon which he has imposed his own standards of presentation. in all, six circulation, eight serials, and six acquisitions systems are described; in each case the description is divided into six parts. first, in a section entitled "environment," the library, its collections, and its users are briefly described. some idea is provided of the library's total budget, or at least its materials budget, and unusual features of the library are given. next, the objectives of the automated system are stated, generally with some indication of what prompted automation to be considered and what features of the previous manual system were less than satisfactory. a section entitled "the computer" describes the hardware used in some detail (and this information is summarized in a table at the end of the book) , and the next section, "the system," gives a lengthy and detailed description of how the system works. the last section in each case is devoted to observations by palmer, indicating the significance to the library of the automated system, and often pointing out problems that have been noted. the least satisfactory section of the book is the final chapter, "summary and observations," in which palmer lays out the stated costs of each system in such a way that they may be directly compared, even though he knows the figures have been derived in various manners and are therefore not directly comparable. palmer's warning to the reader that "unit costs ... should not be compared without noting that they were not computed on a standard basis" makes even more mystifying his arrangement of those costs in tabular form. a second area that seems weak is the suggestion that the book constitutes an effective rebuttal to the criticisms of ellsworth mason. it seems unlikely that anything short of a very thorough systems analysis, showing all of the problems, alten1atives, costs, and benefits of both manual and machine

descriptions to be found in the literature, suggesting by example that many of the individual applications described in the journals, including lola, might well be better than they are. pete1· simmons

weisman states that his work "is not a text on automated information technology," and mechanization is pretty well dismissed in one page of critical discussion. ellsworth mason is singled out for his "amusing, facetious and bitter account of a [sic] melancholy experience at mechanization." use of automated services for information work is covered in less than a page. the work is supposed to be a university-level text and "reference source" on "the practices of information transfer and use" on the "retailer" level. it is almost entirely limited to industrial and government scientific and technical information services. libraries are defined in passing as a "specific type of information system . . . largely limited with some few exceptions to the passive repository function. . . ." however, "if the organization has a library, consultation with the librarian and use of his mechanisms for acquisition and purchase are advisable." it is also suggested that acquisitions are "recommended by the systems advisory committee . . . selected and purchased by the director of the information system and the documentation unit head," and the onorder file is maintained as a list (to be distributed monthly, perhaps) and in card form. the section on cataloging is equally instructive in advising that the acquisition process has provided "subject" as one of three elements needed for descriptive cataloging. the book swings dizzily back and forth from this lilliputian (or is it laputan?) perspective to the more olympian outlook suggested by a seventeen-page appendix which is the text of a charter for the united engineering information service with an expected annual budget of $1.2 million. it also seesaws from the uselessly general to the exquisite detail of an operations manual with hardly a pause for breath. we are told at the start of the chapter on "documentation practicesinformation services" that it "is more efficient to provide [information dissemination services] than to have individuals scurrying about searching for information." a summary of the "procedural flow" follows immediately: "1. ... all requests and inquiries no matter how received or to whom addressed are logged and assigned a control number. 2 .... the head of inquiry services is responsible for monitoring all requests and inquiries. . . . all incoming requests are entered on the inquiry form .... " most examples appear to be drawn from the author's experience as manager of information services, national bureau of standards. some are useful. strauss' scientific and technical libraries: their organization and administration was another wiley-becker-hayes volume issued during the same year. it is impossible to avoid imagining the publisher's marketing division people counting the respective memberships of the special libraries association and the american book reviews 241 society for information science as distinct markets for the two works. however, the first three-quarters of weisman's work is a duplication distinguished from strauss mainly by the shallowness of its coverage and the poverty of its prose. weisman's only notable contribution is thirty pages about information analysis centers, which might be worth a school reading assignment. the assignment will be at some risk, depending .on students' toleration for such words as "essentialness," "beneficialness," "collaborationists," and such phrases as "parameters of data points," as in "an indexed bibliography becomes a more useful document, since it can indicate to a user exactly the type of data contained as well as parameters of data points."

(university of lancaster occasional papers, no.7) university of lancaster library, 1972. 90p. £ 1.00. isbn: 0901699-14-4. in the context of the need for greater managerial expertise in libraries, the state of managerial education in library schools, and the place of games in this education, the authors describe in this document the development of a simplified probablistic model of a loan and duplication system. while it is perhaps the novelty of concept exhibited by the game which first attracts attention, closer examination reveals that the game is but the vehicle upon which is carried a far-ranging analysis of the state of library management. a dynamic model utilizes three input variables-loan period, titles bought, and duplicates purchased-and three output measures-satisfaction level, document exposure, and collection bias-of the effective manipulation of the former within the constraint of budget to illustrate complex interactions within a library system. sufficient flexibility (e.g., variation of loan periods according to popularity of volumes and/ or status of user) enables different policies to be selected to effect the stated objectives of the player (library "manager"). comparison of selected outputs illustrates that while choosing and implementing policies may be simple (a "game editor" interprets a player's decisions to the computer), judging their merits is not. policy (l) decreases collection bias at the expense of average document exposure per issue, while policy ( q) has the opposite effect, for similar costs and total issues; policy (t) increases satisfaction level and decreases collection bias in comparison with policy ( q), at a cost of 8,000 units of expenditure. evaluation of the policy decision rests on a value judgment (as in the real world) . although description of the game and probabilities upon which it is based occupies a considerable portion of the volume, the authors considered not only the practicability of such a game but also its usefulness in teaching and cost of utilization. an appendix devoted to an in-depth study of education for library management concludes that: in britain and, to a lesser extent, the united states this aspect of library education needs considerable strengthening; games such as that described are most suited to specialized courses for experienced librarians but there is a place for similar ones in firstlevel courses; and a larger proportion of the profession needs to comprehend the concepts put forward in this and other studies before better management techniques will be applied to libraries. this volume is an important contribution to the literature of library management, illustrating that the effect that computers can have on the practice of librarianship goes far beyond the mere substitution of machines for clerical workers. george ]. snowball sir george williams unive1·sity library montreal, canada \ orthographic error patterns of author names in catalog searches 93 renata tagliacozzo, manfred kochen, and lawrence rosenberg: mental health research institute, the university of michigan, ann arbor, michigan an investigation of error patterns in author names based on data from a survey of library catalog searches. position of spelling errors was noted and related to length of name. probability of a name having a spelling error was found to increase with length of name. nearly half of the spelling mistakes were replacement errors; following, in order of decreasing frequency, were omission, addition, and transposition errors. computer-based catalog searching may fail if a searcher provides an author or title which does not match with the required exactitude the corresponding computer-stored catalog entry ( 1). in designing computer aids to catalog searching, it is important to build in safety features that decrease sensitivity to minor errors. for example, compression coding techniques may be used to minimize the effects of spelling errors on retrieval ( 2, 3, 4). preliminary to the design of good protection devices, the application of error-correction coding theory ( 5, 6, 7) and data on error patterns in actual catalog searches ( 8, 9) may be helpful. a recent survey of catalog use at three university libraries yielded some data of the above-mentioned kind (10). the aim of this paper is to present and analyze those results of the survey which bear on questions of error control in searching a computer-stored catalog. in the survey, users were interviewed at random as they approached the catalog. of the 2167 users interviewed, 1489 were searching the catalog for a particular item ("known-item searches"). of these, 67.9% first entered the catalog with an author's or editor's name, 26.2% with a title, and 5.9% with a subject heading. approximately half the searchers had a written citation, while half relied on memory for the relevant in94 journal of library automation vol. 3/2 june, 1970 formation. paradoxically, though most known-item searchers tried to match primarily an author and only secondarily a title, there were in the sample of searches many more cases of exact title citation than of exact author citation. imperfect recall of author name of the 1489 "known-item" searches, 1356 could be verified against the actual item. from the total nwnber of searches ( 1260) in which the catalog user had provided an author's (or editor's) name, those works were subtracted which did not have a personal authorship ( 208) or had multiple authors or multiple editors ( 127). this left 925 searches, of which 470 had complete and correct author entries, while 455 contained various degrees of imperfection in the author citation. table 1 gives the distribution of incorrect and/or incomplete author citations. in the study an author's name was defined as incomplete when the first name, or the two initials, or one out of two initials was missing. table 1. incorrect and/or incomplete author names categories university of michigan libraries i ii iii total general library 144 25 6 175 undergraduate library 94 35 4 133 medical library 110 27 10 147 -total 348 87 20 455 in category i (the most numerous) the author's last name was correct, but the author citation as a whole was either incomplete or incorrect; i.e., there were mistakes and/or omissions in the first and middle name or initials. most of the searches in category i were incomplete rather than incorrect. since in category i there is nothing wrong with the author's last name, the searcher's ability to gain access to the right location in the catalog is presumably not impaired as long as the last name is not too common. once the searcher has entered the catalog, he will make use of other clues, such as title or knowledge of the topic, to identify the right item. but if the name is smith or brown or johnson, and the catalog is a large one, to have an incomplete author's name may be equivalent to having no name at all. (in the university of michigan general library catalog, which contains over four million cards, the entry "smith" extends over eight drawers, and the entries "brown" and "johnson" over four drawers each.) in an automated catalog it is easy to limit the set of entries from which the right item has to be selected by intersecting the last name of the author with some other clues. incompleteness of the author name may then not be a serious handicap. orthographic error patternsftagliacozzo 95 category iii includes all searches in which the searcher had an author that turned out to be wrong. the error in this case was not in incompleteness or misspelling of the author's name, but in the identity of the author. no further analysis of this group was conducted. category ii is the one which forms the object o£ the present report. the analysis concerns mainly position and type of errors, and the incidence of errors as related to name length. position of errors in author names the location of errors in the author citation is important for manual systems, such as traditional library card catalogs, as well as for automated systems. table 2 shows the distribution of e in the sample of incorrect author citations from all three libraries, where e is the position of the letter, counting from left to right, in which an error appeared. in the fourteen cases in which more than one error occurred in the same name, only the first error was considered. in a few cases the error involved a string of letters (e.g., friedman for friedberg). in such cases the position of the first letter of the string determined the location of the error. table 2. position of error in last name of author incorrect names e no. % cumulative % 1 2 2.3 2.3 2 11 12.6 14.9 3 11 12.6 27.6 4 19 21.8 49.4 5 13

letters, while the other half had errors in one of the following letters, from the fifth to the eleventh position. the most frequently misspelled is the fourth letter, which is responsible for 21.8% of the total number of errors occurring in the sample. the ordinal number indicating the position of the error is not, by itself, a sufficient indicator of the area where the error occurred. an error in the third letter, for instance, is close to the beginning of the name if the 96 ]ourml of library automation vol. 3/ 2 june, 1970 name is 9 letters long, but close to the end if the name is 4 letters long. in table 3 l indicates the length (the number of letters) of the authot name and pa the location of the error-i.e., the position of the first letter, counting from left to right, where an error appears. the incorrect author names of the sample ( 87) have a length of between 3 and 12 letters. the column on the right of the table, el, indicates the distribution of names of a given length. the row at the bottom of the table gives the distribution of errors occurring in a given position. mistakes are shown to occur anywhere from the first letter to the eleventh letter. when the error consists in the addition of a letter to the end of the correct name, pa is beyond the name itself. the figures which appear next to the diagonal line, on the right, indicate mistakes of this sort. a sununary inspection of the table produces the impression that errors are clustered toward the end of the names, or at least that they are more prevalent in the second half of the name than in the first half. this seems to be a direct consequence of the fact that the first column of the table (errors in position 1) is almost empty. it is tempting to say that errors very rarely occur in the first letter of a proper name. but is this really so? it is true that english-speaking people place particular emphasis on initials, to the extent that initials are often sufficient for identifying well-known figures. the special attention given to the first table 3. position of error vs. length of name length (l) errors (pe) frequency (el) 1 2 3 4 5 6 7 8 9 10 11 3 1 1 4 1 3 5 5 1 2 1 7 6 1 3 6

the scarcity of errors in such a letter. but it is also possible that when errors in the first letter occur, they so transform the name that it becomes unrecognizable. several such authors may have ended up in the category of non-verified authors necessarily excluded from the analysis. it would be interesting to verify whether the "serial-position effect" that some authors found in the spelling of common nouns is present also in the spelling of proper names. according to jensen and to kooi et al., the distribution of spelling errors in relation to letter position closely approximates the serial-position curve for errors found in serial rote learning ( 11, 12). to ascertain if this is the case for author names, a data base much larger than that used for this study would be needed. distribution of errors and length of names is the probability of a catalog searcher misspelling the name of an author dependent to any extent on the length of the name? table 3 shows the frequency of occurrence of names of a given length in the 87 misspelled names (column el). the next step was to calculate the distribution of the length of author names in the whole group of verified author citations provided by the catalog searchers. this group, it should be remembered, does not include multiple authors, multiple editors or nonpersonal authors. the ratio of the corresponding figures in the two distributions will give the percentage of names of a given length having spelling mistakes (table 4) . table 4. probability of errors in recall of author names of a given length length

extremes of length distribution are scarcely 98 journal of library automation vol. 3/2 june, 1970 represented, and this is probably responsible for inconsistencies in the percentage disb·ibution. grouping names into three length categories (i.e., short names, middle-length names, and long names) makes more apparent differences in percentages of incorrect names. the differences are significant at the .01 level of confidence. type of error in author names errors which occurred in the spelling of the last names of authors were grouped into four broad categories: replacement errors, omission errors, addition errors, and transposition errors. while it is true, especially in badly mangled words, that an error can often be said to be of any of several types, it was generally easy to identify the simplest necessary transformation of the letters, and to assign the incorrect name to the type of error corresponding to that kind of transformation. in some cases this meant adding a string of letters or replacing one string by another. altogether the sample of 87 incorrect authors contained 104 errors. eleven names exhibited two errors each, three had three errors, and the remaining just one error. of the 104 errors, 50 were replacement errors; these are cases in which one letter or string of letters of the correct name has been replaced by a different letter or string of letters (e.g. hoiser for hoijer, friedman for friedberg). the most common replacement errors appear in table 5, in order of decreasing frequency. table 5. single-letter replacement errors no. of errors

each replaced just once and the 12 strings of letters. in four cases, the replaced letter was the second of a double letter. there were 34 omission errors in all. four of these involved a string of letters; all the rest were single-letter omissions. eleven single-letter omissions occurred in the last letter of the name (e.g. abbot instead of abbott), and 19 in the middle of the name (e. g. brent instead of orthographic error patternsjtagliacozzo 99 brendt). table 6 gives the frequency distribution of the omitted letters. the asterisk indicates that the omitted letter was the second of a

berelison for berelson) or at the end of it (e.g. haller for halle). in the latter case, the added letter is found beyond the last letter of the correct name (these were the errors on the right of the diagonal in table 3). the distribution of addition errors is shown in table 7. the asterisk indicates that the added letter duplicated the previous letter. table 7. single-letter addition errors no.

(this is not due to the fact that addition and omission errors contained a disproportionately high number of final errors; even when these final errors are excluded, replacement errors still come earlier than other types.) 4) second and third errors in a name have comparatively few replacement errors. acknowledgment this work was supported in part by the national science foundation, grant gn 716. references 1. kilgour, f. g.: "retrieval of single entries from a computerized library catalog file," proceedings of the american society for i nfo1'11ultion science, 5 ( 1968), 133-136. 2. nugent, william r. : "compression word coding techniques for information retrieval," journal of library automation, 1 (december 1968), 250-260. orthographic error patternsjtagliacozzo 101 3. ruecking, frederick h ., jr.: "bibliographic retrieval from bibliographic input; the hypothesis and construction of a test," journal of library automation, 1 (december 1968), 227-238. 4. dolby, james l. : "an algorithm for noisy matches in catalog searching." in: a study of the organization and search of bibliographic holdings records in on-line computer systems: phase i.

used file structure for the storage of indexing information in a document retrieval system. this paper describes a novel method for the computer storage of such an index. the method not only offers the possibility of reducing storage requirements fot an index but also affords more mpid processing of query statements expressed in boolean logic. introduction the inverted index file is a frequently used file structure for the storage of indexing information in document retrieval systems. an inverted index file may be used by itself or with a direct file in a so-called combined file system. the inverted index file contains a logical record for each of the subject headings or index terms which may be used to describe documents in the system. within each logical record there is a list of pointers to those documents which have been indexed by the subject heading in question. the individual pointers are usually in the form of document numbers stored in fixed-length digital form. obviously, the length of the lists will vary from record to record. the purpose of this paper is the presentation of a new technique for the storage of the lists of pointers to documents. it will be shown that this technique not only reduces storage requirements, but that in many cases the time required to search the index is reduced. the technique is useful in systems which use boolean searches. the relative merits of boolean and weighted term searches are beyond the scope of this paper, as are the relative merits of the various possible file structures. the binary vector as a storage device the exact form of each document pointer is immaterial to the user of a document retrieval system as long as he is able to obtain the document he desires. the standard form for these pointers in most automated systems is a document number. note that each pointer is by itself a piece of information. however, if one thinks of a "peek-a-boo" system, the document 308 journal of library automation vol. 7/4 december 1974 pointer becomes simply a hole punched in a card. in this case the position of the pointer, not the pointer itself, conveys the information. the new technique presented in this paper is an extension of the "peeka-boo" concept. a vector or string of binary zeroes is constructed equal in length to the number of documents expected in the system. the position of each vector element corresponds to a document number. that is, the first position in a vector corresponds to document number one and the tenth vector position corresponds to document number ten. a vector is constructed for each subject heading in the system. as a document enters the system, ones are inserted in place of the zeroes in the positions corresponding to the new document number in the vectors for the subject headings used to describe the document. as an example, assume the following document descriptions are presented to a system using binary vectors: document number 1 2 3 subject headings a,b,d c,e a,c the binary vectors for terms a, b, c, d, and e before the insertion of the indexing data would be as follows: subject heading a b c d e vector 000 ... 0 000 ... 0 000 ... 0 000 ... 0 ooo ... ·o after the insertion of the indexing information, the same vectors would appear as follows: subject heading a b c d e vector 101 ... 0 100 ... 0 011 ... 0 100 ... 0 010 ... 0 the binary vector seems to have several advantages over the standard form of storage of document numbers in an inverted file. first, the records are of fixed length since the vectors are all equal in length to the expected number of documents in the system. space may be left at the end of each vector for the addition of new documents. periodic copying of the file may be used to expand the index records with additional zeroes added at the end of each record during the process. consequently, unless binary vector/king 309 there are limitations of size imposed by the equipment, only one access to the storage device will be needed to retrieve the index record for a term. the second advantage offered by the binary vector method appears in the search process. most modern computers have a built-in capability of performing boolean logical manipulations on binary digit vectors or strings. thus, when boolean operations are specified as part of a query, the implementation of the operations within the· computer is considerably easier and faster for binary vectors than for the standard form of inverted files. other investigators of the use of the binary digit patterns or vectors have not fully explored its advantages and disadvantages. bloom suggests, without an explanation or evaluation, the use of bit patterns as the storage technique for inverted files in large data bases in the area of management information systems.1 davis and lin, again in the area of management information systems, propose bit patterns as the means of locating pertinent records in a master file. 2 they do not compare the method with other possible techniques. sammon discusses briefly the use of binary vectors as a storage technique, but dismisses it on the basis that the two-valued approach obviates the possible assignment of weights to index terms in describing documents. 3 gorokhov discusses the use of a modified binary vector approach in a document retrieval system implemented on a small soviet computer.4 faced with the need to minimize storage requirements for his inverted file, gorokhov concentrated on developing a technique for locating and removing strings of zeroes occurring in the binary vectors used within the system. since these zeroes represent the absence of information they could be removed if there were a way to indicate the position in the original vector of the ones that remained. he proposed the removal of strings of zeroes and the inclusion of numeric place values with the remaining vector elements. his result is a file with variable-length index records. the abandoning of the pure binary vector obviates the process, and gorokhov found it necessary to expand the vector elements into the original vector before logical operations could be applied. even though he does not state so explicitly, gorokhov seems to have found his method more efficient than the standard inverted file. gorokhov' s suggestion has led to the development of an algorithm for the compression of binary vectors. heaps and thiel have also discussed the use of compressed binary vectors as the basis of an inverted index file. 5• 6 aside from a brief description of the method for implementing the concept, they offer no comparison of the binary vector with the standard inverted file. storage requirements an immediate reaction to the concept of binary vectors is to state that they will obviously take more storage space than the standard inverted file. a closer study shows that this is not always the case. the storage requirements for the two types of files may be calculated as follows: 310 journal of library automation vol. 7/4 december 1974 d·n 1. mbv = 8 bytes 2. msr = d · i · k where: ( binary vector file) (standard inverted file) m = storage requirements in bytes d = number of documents in the system n = number of index terms in the system i = average depth of indexing in the system k = size in bytes of a document number stored in the file using equations 1 and 2 we find that the storage requirements for the binary vector file are, in fact, less than the requirements for the standard inverted file if n < 8 •] • k. it is well lmown that the distribution of the use of index terms follows a logarithmic curve. in simple terms, one might say that a few terms are used very frequently and many terms are used infrequently. this condition implies that in a binary vector file the records for many terms will contain segments in which there are no "ones" in any byte. a method for removing these "zero" bytes is called compression. compression algorithm the technique for the compression of binary vectors as described here is designed specifically for the ibm 360 family of computers and similar machines. the extension to other machines should be obvious. within the ibm 360 the byte, which contains eight binary digits, is the basic storage unit, and with the eight binary digits it is possible to store a maximum integer value of 255. for the purpose of describing a proposed compression algorithm for the binary vector in the ibm 360, the term subvector will be defined as a string of contiguous bytes chosen from within the binary vector. a zero subvector will be a subvector each of whose bytes contains eight binary zeroes. a nonzero subvecto1· will be a subvector each of whose bytes contains at least one binary one. to compress a binary vector in the ibm 360 the following steps may be taken: 1. divide the binary vector into a series of zero subvectors and nonzero subvectors. subvectors of either type may have a maximum length of 255 bytes. for zero subvectors longer than 255 bytes, the 256th byte is to be treated as a nonzero byte, thus dividing the long zero subvector. 2. each nonzero subvector is prefixed with two bytes. the first of the prefix bytes contains the count of zero bytes which precede the nonzero subvector in the uncompressed vector. the second prefix byte contains a count of the bytes in the nonzero subvector. 3. the compressed vector then consists of only the nonzero subvectors together with their prefix bytes. 4. a two byte field of binary zeroes will end the compressed vector. binmy vector/king 311 the compression of the vectors creates variable-length records and removes the advantage of having records which are directly amenable to boolean manipulation. the effect of file compression on such manipulation in the search process is not as severe as it might appear. for the search process, the compressed vector may be expanded into its original form. the process of expansion of the binary vectors is relatively simple, and since only those index term records which are used in a query need to be expanded at the search time, the search time is not significantly affected. as an example of the use of the compression algorithm consider the following binary vector. 01100000/10000000/ seven zero bytes j00000001j10000000j ... the slashes indicate the division of the vector into bytes. the vector might be read as indicating the following list of document numbers: 2, 3, 9, 80, and 81. in a standard inverted file with each document number assigned three bytes of storage, fifteen bytes would be required to store these numbers. the compressed vector which results from the application of the algorithm is the following: 00000000j00000010j01100000/10000000j00000111/00000010/ 00000001/10000000/ ... again the slashes separate the vector into bytes. for the purpose of the following discussion consider each byte in a vector to be numbered sequentially beginning with byte one at the left. in the uncompressed vector bytes one and two form a nonzero subvector. consequently, the first four bytes in the compressed vector can be interpreted as follows: byte one. binary zero indicating that no zero bytes were removed preceding this subvector. byte two. binary two indicating that the following nonzero subvector is two bytes long. bytes three, four. bytes one and two of the original vector. bytes three through nine of the original vector are a zero subvector, and bytes ten and eleven form a second nonzero subvector. consequently, the second four bytes of the compressed vector are interpreted as follows: byte five. binary seven indicating that a zero subvector of seven bytes has been removed. byte six. binary two indicating that the following two bytes are a nonzero subvector. bytes seven, eight. bytes ten and eleven of the original vector. thus the binary vector has been reduced from eleven bytes to eight 312 journal of library automation vol. 7/4 december 1974 bytes while the space required to record the document numbers in the standard inverted file remains fifteen bytes. memory requirements for the standard inverted file and the binary vector file to compare memory requirements for the standard inverted file and the compressed binary vector file, we base our comparison on the total number of postings in the file. in the standard inverted file the storage space for the postings is equal to the number of postings times the length of a single posting, which is usually two, three, or five bytes. memory requirements for the compressed binary vector file are more difficult to estimate because the distribution of document numbers within the record for each index term is not known. the fact that a single byte in the binary vector file may contain between zero and eight postings is extremely important. the worst possible case occurs if the postings in the binary vector are spaced in such a way that each nonzero byte contains only one posting, and these bytes are separated by zero bytes. consider the following example: ... /00000000/00010000/00000000/00000100/ ... in this case the compression algorithm will remove the zero bytes, but will add two bytes (the prefix bytes) for each nonzero byte. the resulting compressed vector will be essentially the same length as the standard inverted file record if each posting is three bytes long in the standard inverted file. it might seem that the distribution of one posting per byte for the entire vector represents an even worse situation. it is clear that the compression algorithm will, in this case, not reduce the size of the vector. however, it must be remembered that in the standard inverted file each posting will require at least two bytes and perhaps three bytes. thus, the length of the record in the standard inverted file is two or three times longer than the corresponding binary vector regardless of compression. in data used in two model retrieval systems prepared to compare the standard inverted file and the binary vector file there are 6,121 documents with a total of 94,542 postings. an examination of the binary inverted file for the model systems discloses that there are only 55,311 nonzero bytes in the binary vector file. thus there seems to be some form of clustering of the document numbers in each index term record. if each nonzero byte in this binary vector is isolated by zero bytes, two prefix bytes would be added for each byte. thus the total memory requirements for the postings in the compressed file would be 165,933 bytes. less storage space is required if some nonzero bytes are contiguous. on the other hand, the standard inverted file will require 189,084 bytes if a two-byte posting is used, or 283,626 bytes if a three-byte posting is used. further study of the clustering phenomenon is needed. binary vector /king 313 model retrieval systems to test some of the conjectures about the differences between the standard inverted file and the binary vector file, two model systems were prepared for operation on an ibm 360/67. details of the systems and pl/1 program listings are available elsewhere. 7 the data base used was obtained from the institute of animal behavior at rutgers university. in the data base 6,121 documents were indexed by 1,484 index terms. a total of 94,542 postings in the system gives an average depth of indexing of 15.4 terms per document. both inverted files were stored on ibm 2314 disc storage devices. to ease the problem of handling variable-length records in both files the logical records for each index term were divided into chains of fixed~ lehgth physical records. for the standard inverted file a physical record size of 331 bytes was chosen. the entire file required 702,713 bytes including record overhead. for the uncompressed binary vector file a physical record size of 1,286 bytes was chosen to include overhead and space for up to 10,216 document numbers. when the compression algorithm was applied, with a physical record length of 130 bytes, the memory requirements for the binary vector file were reduced to 281,450 bytes, or 41 percent of the space required to store the standard inverted file. a series of forty searches of varying complexities were run against both files. the "time" function of pl/1 made it possible to accumulate timing statistics which excluded input/output functions. search times for the binary vector file include expansion of the compressed vectors, boolean manipulation of the vectors, and conversion of the resultant vector into digital document numbers. the times for the standard inverted file are for the boolean manipulation of the lists. the following points were noted in the analysis of the times: 1. in twenty-two of the forty queries for which comparative timings were obtained, the search of the binary vector file was faster, in one case by a factor of thirty-five. in the eighteen cases in which the search of the standard inverted file was faster, the search of the standard inverted file was at most 6.17 times faster. 2. the range of the total times for the binary vector file was .79 seconds to 9.72 seconds. the range for searching the standard inverted file was .15 seconds to 202.98 seconds. the fact that the search times for the binary vector file are within a fairly narrow range, in contrast to the wider range of times for searching the standard inverted file, has important implications for the design of an on-line interactive document retrieval system. in such a system it is important that the computer respond to users' requests not only rapidly but consistently. the narrower range of the search times provided by the binary vector file will assist in producing consistent times. 3. the search times for the binary vector file, exclusive of expansion and conversion times, are unaffected by the number of postings con314 journal of library automation vol. 7/4 december 1974 tained in the index terms used in a query. on the other hand, the number of postings in the records used from the standard inverted file appears to cause the differences in search times for that file. to test the conjectures! that 1. search times for the binary vector file are related to the number of index terms in the query, and 2. search times for the standard inverted file are related to the number of postings in the index terms in the query, a correlation analysis was performed. the following correlation coefficients were obtained: v a1'iables 1' number of terms in query and search .960 times for the binary vector file. number of postings in query terms and .979 search times for standard inverted file. the relationships indicated above are significant at the .001 level. no attempt was made to compute an average search time per term for the binary vector file or average search time per posting for the standard inverted file. such times would have meaning only for the model systems. summary the binary vector is suggested as an alternative to the usual method of storing document pointers in an inverted index file. the binary vector file can provide savings in storage space, search times, and programming effort. references 1. burton h. bloom, "some techniques and trade-offs affecting large data base retrieval times," proceedings of the acm 24 ( 1969). 2. d. r. davis and a. d. lin,

in the digital age heather b. terrell information technology and libraries | december 2015 55 abstract in a literature survey on how reference collections have changed to accommodate patrons’ webbased information-seeking behaviors, one notes a marked “us vs. them” mentality—a fear that the internet might render reference irrelevant. these anxieties are oft-noted in articles urging libraries to embrace digital and online reference sources. why all the ambivalence? citing existing research and literature, this essay explores myths about the supposed superiority of physical reference collections and how patrons actually use them, potential challenges associated with electronic reference collections, and how providing vital e-reference collections benefits the library as well as its patrons. introduction reference collections are intended to meet the immediate information needs of users. reference librarians develop these collections with the intention of using them to answer indepth questions and to conduct ready-reference searches on a patron’s behalf. library users depend on reference collections to include easily navigable finding tools that assist them in locating sources that contain reliable information in a useful, accessible format and can be accessed when the information is needed. the expectation for print reference collections is that they are comprised of high-use materials—the very reason for their designation as noncirculating items is ostensibly so that materials are available for on-demand access by both patrons and staff, who use them frequently. however, librarians and patrons alike have acquired what margaret landesman calls “online habits,” to wit, the most-utilized access point to information is often the 24/7 web.1 in a wired world, where the information universe of the internet is not only on our desktops, but also in our pockets and on our fashion accessories, the role of the print reference collection is less relevant in supporting information and research aims. in no other realm have the common practices of both users and librarians changed more than in how we seek information. nevertheless, a technology-related panic seems to be at the boil, with article titles like “are reference books becoming an endangered species?”2 and “off the shelf: is print reference dead?”3 words like “invasion” are used to describe the influx of electronic reference sources. we read about the heather b. terrell (hterrell@milibrary.org), a recent mlis degree graduate from the school of library and information science, san jose state university, is winner of the 2015 lita/ex libris student writing award. mailto:hterrell@milibrary.org reference is dead, long live reference: electronic collections in the digital age | terrell | doi: 10.6017/ital.v34i4.9098 56 “unsustainable luxury” of housing hundreds—sometimes thousands—of unused books on the open shelves. all this handwringing leads us to wonder why librarians in the field need this much coaxing to be cajoled into weeding their print reference collections in favor of electronic reference resources. does this format transition really constitute such a dire situation? what if the decline of print reference usage isn’t a problem? and what’s so luxurious about dusty, overcrowded shelves full of books no one cares to use? in “the myth of browsing,” barclay concludes that “the continued over-my-dead-body insistence that no books be removed [from libraries] is an unsustainable position.”4 a survey of the relevant literature reveals that staff resistant to the transition from print to electronic reference collections often share three core presumptions about reference: • users prefer using print sources, and the importance of patrons’ ability to browse the physical collection is paramount. • the reliability of web-based reference sources may be questionable, especially when compared with the authority of print reference materials. • access to print materials is the only option that certain users (namely, those without library cards) have for being connected to information. there also seems to be a more subtle assumption at play in the print vs. electronic reference debate—that print books are more “dignified,” cultivating a scholarly atmosphere in the library. certain objections to removing print reference collections to closed stacks and using the newly freed public space to build a cooperative learning commons, for instance, tend to devolve into hysterics about the potentiality of libraries becoming “no better than a starbucks.” the “no better” variable in this equation is a cosmetic one—librarians aren’t worrying about libraries serving up a flavored “information latte” for vast profit margins—they are worrying that libraries will be perceived as a place to loiter, use the internet, and “hang out,” rather than a place for serious study. one thing for librarians who worry about this potential outcome to consider is that loyal coffee shop denizens would be up in arms to learn that their favorite shop was being closed or its services being reduced or eliminated. the implications are clear. perhaps libraries should consider the café model: a collaborative “no-shushing” zone—the difference between a library and a coffee house being that at a library, people are able to explore, learn, and be entertained using the resources provided by the institution. at homer babbidge library at the university of connecticut, staff considered it important to “maintain a vestige of the reference collection, so that students were reminded they had entered a special place where scholarship was tangible.”5 however, users considered the underutilized stacks of books a waste of space that could be better used for cooperative work areas or information technology and libraries | december 2015 57 computer access stations. the students’ needs and interests were heeded, and homer babbidge library’s learning commons has been a successful endeavour. reference collections: history and purpose brief points about the history of reference services lend context to the arguments presented in favor of building electronic reference collections. grimmelman points out that “it’s almost a cliché to assert that the internet is like a vast library, that it causes problems of information overload, or that it contains both treasures and junk in vast quantities.”6 from the earliest dedicated reference departments to the 24/7 reference model developed in response to progressing technology, tyckoson affirms that “one thing remains constant—users still need help. the question . . . is how to provide the library’s users with the best help.”7 browsing collections in libraries are newer than one might assume. prior to world war ii, academic library faculty could browse to find reference materials that met the information needs of students, but undergrads weren’t even allowed in the stacks.8 in public libraries, reference collections were open to users, but reference rooms were considered to be, first and foremost, the domain and workplace of the reference.9 this raises the question, what is the domain and workplace of the contemporary reference librarian? arguably, the answer to this query is wherever the information is, for example, online. ready reference collections arose from the need to make the most commonly used resources in the library convenient and readily available for patron use.10 the most commonly used resources in contemporary libraries are those found online—again, where the information is. both users and librarians now turn to the web as the first resort for answering quick reference queries, and they turn to online databases and journals for exploring complex research questions. meanwhile print works that were once used daily sit moldering, gathering dust on the shelves either because they are outdated or because no one thinks to find them when the answer is available at the swipe of a finger or the click of a mouse from where they sit, whether that’s in the library or in, ahem, a coffee shop. “the convenience, speed, and ubiquity of the internet is making most print reference sources irrelevant,” tyckoson says.11 print preference, browsing collections library use is increasing—but, as landesman and others point out, it is increasing because users want access to computers, instruction in technology, study spaces, or just a place to be that’s not home, not school, and not work. users do not come to the library for reference sources— researchers and scholars prefer to access full-text works via their computing devices.12 the argument that users prefer print sources is antiquated, and the emphasis on building browsing collections of physical reference materials reflects a misguided notion that users crave tactile information. landesman is blunt: “when it is a core title, users want it online.”13 reference is dead, long live reference: electronic collections in the digital age | terrell | doi: 10.6017/ital.v34i4.9098 58 statistics bear her assertions out. studies show that usage of print reference collections is minimal and that users strongly prefer online access to reference materials. • at stetson university, usage statistics gathered during the 2003–4 academic year showed that only 8.5 percent of the library’s 25,626 reference volumes were used during that period.14 • a year-long study by public libraries revealed that only 13 percent of winter park (fl) public library’s collection of 8,211 reference items was used.15 • when texas a&m university converted its reference collection’s primary format from print to e-books, a dramatic increase of the e-versions of reference titles was recorded.16 • in a survey of william & mary law library users, a majority of respondents indicated that they consciously select online reference sources over print, citing convenience and currency as top reasons for doing so.17 scanning the shelves may seem to some to be the most intuitive way to search for information, but in actual practice, browsing is ineffective—books at eye level are used more often, patrons are limited to sources not being used by another patron at any given moment, and overcrowding of the shelves results in patrons overlooking useful materials.18 browsing is the least effective way for patrons to “shop” a collection. searching by electronic means overcomes the obstacles inherent in browsing the physical shelves when using well-designed search algorithms that employ keywords on the basis of accurate metadata. landesman indicates that if librarians commit to educating patrons on the use of the reference databases, ebooks, and websites they offer, online reference will be “a huge win for users.”19 it should be noted: no one suggests that print reference should be eliminated entirely, at least not yet. smaller print reference collections result in better-utilized spaces; they ensure that remaining resources in the physical collections are used more effectively—only the items that are actually high-use are included, which makes these sources easier to locate; books formerly classified as reference materials are able to circulate to those interested in their specialized content. smaller print reference collections serve patrons in myriad ways, including freeing up funds that can be used to enhance electronic reference collections. digital reference services are just another way of organizing information—there is no revolution here, unless it is in providing information with more efficiency—with breadth, depth, and access that surpasses what is possible via a print-only reference collection. the inevitable digital shift is a very natural evolution of patron-driven library services rather than cause for consternation on the part of library service providers. web reliability: google and wikipedia those who argue that the reliability of online sources is questionable are typically referring to google results and wikipedia entries, which have little bearing on a library’s electronic collections information technology and libraries | december 2015 59 of databases and e-books, but has plenty to do with a library’s reference services: these two sources are very often used in lieu of printed fact-finding sources such as atlases, subject or biographical dictionaries, and specialized sources like bartlett’s familiar quotations—which was last printed in 2012 and has recently gone digital. for questions of fact, google is often a convenient and “reliable enough” source for most queries; authority of the results yielded by a google search is not always detectable, and is sometimes intentionally obscured, so the librarian must vet results carefully and select the most reliable sources when providing ready reference to patrons. however, google is far more than just its main search page. for instance, google scholar allows searchers to locate full-text articles as well as citations for scholarly papers and peer-reviewed journal articles. in general, there are many tools on the web, and librarians must expend effort determining how to make the best use of each. in particular, google is better suited to some information tasks than others—it’s up to the librarian to know when to use this tool and when to eschew it. wikipedia has been the subject of much heated debate since its inception in 2001, but in a study conducted by nature magazine, the encyclopedias britannica and wikipedia were evaluated on the basis of a review of fifty pairs of articles by subject experts and found to be comparable in terms of the number of content errors—2.9 and 3.9, respectively.20 deliberate misstatements of fact, usually in biographical entries, are cited as evidence that wikipedia is utterly unreliable as a reference source. in fact, print sources have been plagued with the same issues. for many years, the dictionary of american biography contained an entry based on a hoax claiming a (nonexistent) diary of horatio alger—and while the entry was removed in later editions, the article was still referred to in the index for several years after its removal.21 if anything, it seems that format might provide a false sense of assurance that a source’s authority is infallible. all reference sources include bias, and all will include faulty information. the major difference between print and electronic sources is that in the digital era, using the tools of technology, these errors can be corrected quickly. what some see as declining quality of a source based on its format is simply a longstanding feature of human-produced reference works, dissociated from any print vs. web debate. access: collection vs. policy some academic and public libraries intend to decrease or discontinue purchasing print-based reference sources so funds can be diverted to build electronic reference collections; they weed print reference to make room for information commons containing technology used for accessing these electronic collections. the basic assumption in the objection to this practice is that the traditional model of in-person reference is integral to a functioning reference collection, that access to information depends on that information being printed on a physical page. reference services are provided virtually via chat, im, and email. reference services are provided via the library’s website. reference services are provided by roving librarians, reference is dead, long live reference: electronic collections in the digital age | terrell | doi: 10.6017/ital.v34i4.9098 60 librarians engaging in one-on-one literacy sessions, and in large-group training sessions. long gone are the days of the reference librarian who waits patiently at her station for a patron to approach with a question. since the reference services model no longer mandatorily includes a stationary point on the library map, nor does providing quality reference depend solely on the depth and breadth of the print reference collection, how are print reference collections used? as indicated previously, about 10 percent of print reference collections are used by patrons on a regular basis. concern for the information needs of library users who do not have library cards is well-intentioned, but the question remains: if 90 percent of a collection goes unused, even when those users without library cards have access to these materials, is the collection useful? as stewart bodner of nypl says, “it is a disservice to refer a user to a difficult print resource when its electronic counterpart is a far superior product.”22 how users want to receive their information matters—access should not depend on whether a user can obtain a library card. for those libraries with high concentrations of patrons who do not qualify for library cards (e.g., individuals who do not have a fixed home address, or who cannot obtain a state-issued id card), libraries might reconsider their policies rather than their collections. computer-only access cards can be provided on a temporary basis for visitors and others who are unable to obtain permanent cards. san francisco public library recently instituted a welcome card for those members of the community who cannot meet identification requirements for full library privileges. the welcome card allows the user full access to computers and online resources and permits the patron to check out one physical item at a time.23 when compared with purchasing, housing, and maintaining vast print reference collections, this is a significantly less costly and far more patron-centered solution to the problem of access to electronic information sources— librarians should be advocates for users, with the goal being access to knowledge, no matter its format. conclusion: building better hybrid collections most library professionals agree that libraries should collect both print and electronic sources for their reference collections, but the ratio of print to digital is up for debate. as more formats with improved capabilities appear, researchers find that patrons prefer those sources that provide them with the best functionality. it is essential to look to the principles on which reference services are founded. one of those principles is to build collections on the basis of user preferences. librarians must consider what the reference collection is for and whether assumptions about patron preferences are backed by evidence. in essence, considering what “reference” means to users rather than defaulting to the status quo. a reference collection development policy must be based on what is actually used often, not on what has the potential to maybe be used sometime in the future. the library is not an archive, preserving great tomes for posterity—the collections in a library are for use. with less emphasis on print materials, librarians might focus on the wealth of sources available electronically via information technology and libraries | december 2015 61 databases and ebooks, as well as open-source, free online resources. librarians must cultivate an understanding of the resources patrons use and the formats in which they prefer to access information. as heintzelman and coauthors state, “a reference collection should evolve into a smaller and more efficient tool that continually adapts to the new era, merging into a symbiotic relationship with electronic resources.”24 rules of reference that were devised when print works were the premier sources of reference information no longer apply. reference librarians must lead the way in responding to the digital shift—creating electronic collections centered on web-based recommendations, licensed databases of journals, and ebooks—with a focus on rich, interactive, and unbiased content. weeding reference collections of outdated and unused tomes, moving some materials to the closed stacks while allowing others to circulate, and building e-book reference collections allows libraries to provide effective reference services by cultivating collections that patrons want to use. much of the transition from print to electronic reference collections can be accomplished by ensuring that resources are promoted to patrons and staff, that training in using these tools is provided to patrons and staff, that librarians become involved in the selection of digital collections, and that the spaces where print collections were formerly housed are used in ways the community finds valuable. one need not worry about the “invasion” of e-reference or the “death” of print reference. the two can coexist peacefully and vitally, as long as librarians maintain focus on selecting the

standards for library automation and isad's committee on technical standards for library automation (tesla) the 1'0le of isad's committee on technical standards for library automation is examined and discussed. a p1'dcedu1'e fo1' the reaction to and initiation of standards is described, with reference to relevant standards organizations. the development, implementation, and maintenance of standards might best be characterized as the complexity of simplification-complex insofar as a standard represents a universally applicable ideal which is usually the result of arduous negotiation and compromise; simplification since a standard, once recommended and followed in practice, forms a firm reference point for the achievement of specified objectives. thus, if a standard exists, it can be referenced or used immediately and variant wheels do not have to be invented. unfortunately, to use, reference, or advocate a standard requires an awareness of available standards or the process whereby standards evolve. it is at this point that standards again become complex-in fact, they become a maze, which perhaps can be characterized by questions such as: is there a standard already? who is responsible for it? where are copies of this standard available? and so on (a maze familiar, certainly, to all of us). n is precisely to address the mazelike aspect of the standards "game" that the committee on technical standards for library automation ( tesla) has been established. in short, tesla intends to act as a twoway clearinghouse, hopefully to bring user and supplier into a meaningful dialogue wherein the requirements of both might be satisfied. technical standards and data dependence within this context the emphasis by tesla shall be on technical standards for library automation (e.g., standards relating to electronic data processing devices and techniques). concurrently, however, there are instances where device and data become inseparably linked. for example, the standatds fot libraty automation 127 relationship between the physical dimensions of a machine-readable patron badge and the amount and, therefore, type of data which can be me~ chanically encoded in it; or the character set used by a terminal and the minimum processing potential and, thus, hardware which must be internal to the terminal to receive, transmit, and display that character set. because it would be foolish to ignore this relationship, tesla in its clearinghouse function will stress and foster the involvement of individuals or organizational units within the american library association wherever data-dependent technical standards are involved. ala-originated and maintained technical standards though certainly no mystery, there is little evidence that the direct cost and personal involvement for a published and practiced standard is popularly known. for example, it has been indicated by those within the standards business that an adopted standard might culminate an investment of over a million dollars and represent the expenditure of tens of man-years. the cost, for example, leading to and including the final publication by the american national standards institute (ansi) of the standard for bibliographic information interchange on magnetic tape (ansi z39.21971), more popularly known as marc, has not been published. it is suspected, however, that the cost of the marc standard was monumental. in short, and by way of this example, it can be safely assumed that neither the american library association nor isad nor tesla will become standards organizations in the strict sense of the word. in fact such a capability is not desirable, since organizations such as ansi, electronics industry association (eia), institute of electronic and electrical engineers (ieee), national microfilm association ( nma), etc., exist and are geared specifically to this activity. rather, the american library association and isad should, and must, participate actively in the standards processes available to them to insure a meaningful user-voice in the development of standards by those organizations. to provide for participation in the standards process at the membership level is precisely tesla' s role. thus, when placed in operation, such standards will reflect the library community's requirements, contributing to and fostering library automation rather than hindering it. at least one of the anticipated results would be the development of equipment addressing library needs directly, and so preclude the custom fabrication of specialty devices which while satisfying the needs of a few libraries-expensively, cannot satisfy libraries in generaleconomically. what is provided by tesla? tesla specifically has established a procedure whereby the membership of the american library association might either teact to proposals for standards regardless of origin, or initiate proposals for standards for membership reaction. the results of this procedure, whether reactive or initia128 journal of library automation vol. 7/2 june 1974 tive, would be communicated to the membership in terms of the status and position taken for each proposal, and to the originator and to ala's official representative in full detail for subsequent application. the tesla procedure the procedure is geared to handle both reactive (originating from the outside) and initiative (originating from within ala) standards proposals to provide recommendations to ala's representatives on existing, recognized standards organizations. to enter the procedure for an initiative standards proposal the member must complete an "initiative standards proposal" using the outline which follows: initiative standard proposal outline the following outline is designed to facilitate review by both the committee and the membership of initiative standards requirements and to expedite the handling of initiative standards proposals through the procedure. since the outline will be used for the review process, it is to be followed explicitly. where an initiative standard requirement does not require the use of a specific outline entry, the entry heading is to be used followed by the words "not applicable" (e.g., where no standards exist which relate to the proposal, this is indicated by: vi. existing standards. not applicable). note that the parenthetical statements following most of the outline entry descriptions relate to the ansi standards proposal section headings to facilitate the translation from this outline to the ansi format. all initiative standards proposals are to be typed, double spaced on 8%" x 11" white paper (typing on one side only). each page is to be numbered consecutively in the upper right-hand corner. the initiator's last name followed by the key word from the title is to appear one line below each page number. i. title of initiative standard proposal (title). ii. initiator information (forward). a. name b. title c.

in addition to text exposition where applicable (specification of the standard). please note that the outline is designed to enable standards proposals to be written following a generalized format which will facilitate their review. in addition, the outline permits the presentation of background and descriptive information which, while important during any evaluation, is a prerequisite to the development of a standard. the reactor ballot (figure 1) is to be used by members to voice their recommendations relative to initiative standards proposals. the reactor ballot permits both "for" and "againsf' votes to be explained permitting the capture of additional information which is necessary to document and communicate formal standards proposals to standards organizations outside the american library association. as you, the members, use the outline to present your standards protesla reactor ballot reactor information name __________________ __ title organization address city___

ballot posals, tesla will publish them in ]ola-tc and solicit membership reaction via the reactor ballot. throughout the process tesla will insure that standards proposals are drawn to the attention of the applicable american library association division or committee. thus, internal review usually will proceed concurrent with membership review. from the review and the reactor ballot tesla will prepare a majority recommendation and a minority report on each standards proposal. the majority recom130 journal of library automation vol. 7/2 june 1974 receipt screen division rej/acp1 publish

originator, and to the official american library association representative on the appropriate standards organization where it should prove a standards for library automation 131 source of guidance as official votes are cast. in addition, the status of each standards proposal will be reported by teslain jola-tc via the standards scoreboard (figure 2). the committee ( tesla) itself will be nonpartisan with regard to the proposals handled by it. however, the committee does reserve the right to reject proposals which after review are not found to relate to library automation. tesla's composition tesla is comprised of representatives both from the library community and library suppliers to insure a mix of both users and producers for its review of standards proposals. in addition, rotating membership on tesla will insure a continuing movement of voices from different segments of the library and library supplier communities to shortstop the pressing of vested interests. at this time, the members of tesla and the term for each are: ms. madeline henderson chairperson, task force on automation of library operations and federal library committee u.s. department of commerce/nos

ends: 1976 in addition to acting as a clearinghouse for standards for isad, and the maintenance of the standard proposal and reactor ballot procedure, tesla intends to urge the establishment of an ala collection of stan132 journal of library automation vol. 7/2 june 1974 dards applicable to libraries to handle requests for information from the library community. thus, while currently each member is left to "do it himself," there appear to be definite economies in the centralization of such a collection and the periodic publication of indices to relevant standards. sources of information relating to standards to provide a source of guidance at this time for the types of available standards, to list the many existing standards, and to index the originating standards organizations would consume several issues of jola. therefore, in the following are very brief recapitulations of the more relevant organizations impacting library automation standards. the list is very incomplete as might be expected. for those interested in a comprehensive review of standards, global engineering, 3950 campus drive, newport beach, ca 92660, maintains and annually publishes their directory of engineering document somces .. this directory, now in its second edition, lists over 2,000 standards organizations and the prefixes used by those organizations in publishing their standards, to permit global engineering's customers to specify standards for purchase. ( global engineering's primary function is the sale of original copies of standards and specifications.) american national standards institute, inc. (ansi)-the american national standards institute, inc. ( 1430 broadway, new york; ny 10019) does not write standards. rather, ansi has established the procedures and guidelines to be followed in the development of standards that will be labeled american national standards. the actual work is done by ansi members and other interested groups and individuals, using the ansi procedures in the development of standards. only after these groups have demonstrated to ansi's satisfaction that the proposed standard has been developed in accordance with the procedure established by ansi will it be approved and published as an american national standard. in addition, ansi publishes materials relating to standards, of which the ansi reporter, a journal dedicated to standards, probably represents the single best source for information relating to current standards issues. however, the scope of ansi is very broad. thus for library and library automation activities specific committees of ansi, rather than ansi itself, are relevant; specifically, ansi committees: ph5 (microfilm). see national microfilm association below. x3 ( computers and information processing); x4 (business machines and supplies). both of these subcommittees are sponsored by the computer and business equipment manufacturers' association ( cbema), which is also their secretariat. cbema ( 1828 l st. nw, washington, dc 20036) periodically provides indices to the published standards of x3. an insight into the breadth of x3's activities can be implied from figure 3, ansi x3 standards committee organization. x3 currently has standards fo1' library automation

vol. 1/2 june 1974 over fifty member organizations. the ala representative on x3 is mr. james rizzolo of the new york public library. an excellent overview of x4's scope and activities was published in the secretary (nov. 1973) under the title "what's being done about office equipment standards." from the library viewpoint x4' s activities in credit cards, typewriter keyboards, and forms are of interest. at this writing x4 has nine user, fifteen producer, and nine general interest members. the ala is not currently represented on x4. z39 (library work, documentation and related publishing practices) sponsored by the council of national library associations. with thirtysix subcommittees ( sc), z39 covers library related activities from machine input records ( sc/2) through standard order forms ( sc/36). it was through z39 that marc became the american national standard (z39.2-1911). z39 publishes a quarterly entitled news about z39. z39 is located at the school of library science, university of north carolina, chapel hill, nc 27514. fifteen standards have been published by z39. the ala representative to z39 is fred blum of eastern michigan university, ypsilanti, whose excellent summary of z39 appears in the winter 1974 issue of library resources & technical services. national microfilm association (nma)-the national microfilm association has an organization of standards committees and a standards board as shown in figure 4. information relating to their standards is published from time to time in the ]oumal of mic1·ographics. a recent article, entitled "standards: nma standards committee scope of work," (vol. 7, no. 1 [sept. 1973] ), briefly describes the subcommittees internal to nma's standards organization and the scope of each. of particular interest to libraries is the sponsorship by nma of ansi-ph5. micrographic standards are listed in an nma publication ( rr1-1974 resource report). copies of this resource report may be obtained by contacting the nma at suite 1101, 8728 colesville rd., silver spring, md 20910. international organization for standardization (iso)-this organization is truly international with representatives from thirty-five nations. the secretariat of iso is ansi (see above). while iso parallels ansi in its coverage, it differs organizationally. thus, the committees/subcommittees of ansi have in large measure their equivalent technical committees, subcommittees, and working groups in the iso. standards developed by the iso and published by them are reported regularly in the ansi reporter (referred to above). most recently, the january 11, 1974 ansi reporter contained an article outlining iso publications and describing five iso titles. marc, by the way, is also iso standard 2709. the iso technical committees ( tc) of immediate interest to library automation are tc 37 (terminology), tc 46 (documentation), tc 95 (office machines), and tc 97 (computers and associated information processing systems, nma standards board i i i i i i microfiche inspection & materials & operational public equipment quality con. supplies practices records i i i i i i microdrafting terminology info. storage

libmry automation vol. 7/2 june 197 4 peripheral equipment and devices, and media related thereto). as an indication of the technical areas covered by tc 97, its organization is shown in figure 5. electronic industries association (eia)-the electronic industries association maintains a broad variety of standards for hardware and related peripheral equipment. such areas as cathode ray tube (crt) terminals, the luminescence of cathode ray tubes themselves, television transmission, and data communications are dealt with by the eia standards. an excellent source of eia standards is the publication produced by the eia entitled index of eia and jedec standards and engineering publications ( 1973 revision and no. 2). copies are available through the electronic industries association, engineering department, 2001 i st. nw, washington, dc 20006. the ala is not a member of the eia, by definition. the institute of electt·onic and electrical engineers (ieee)-the institute of electronic and electrical engineers, inc. is a professional organization which, in addition to its professional activities, maintains standards. many of these standards relate to library automation in such areas as keyboards for terminals and transmission types for data communications. while each monthly issue of the ieee publication spectrum contains annotated lists of new standards, a full index to the ieee standards is available by contacting the ieee headquarters, 345 e. 47 st., new york, ny 10017. national bureau of standards (nbs)-the national bureau of standards, u.s. department of commerce, has the responsibility within the federal government for monitoring and coordinating the development of information processing standards and publishing proved data standards for data elements and codes in data systems. thus, the national bureau of standards works closely with federal departments and agencies, the american national standards institute (ansi), and the international orgatlization for standardization (iso). of specific interest to library automation are the fedeml information processing standards (fips) and the fips index published by nbs. the annual fips index (fips pub 12-1) is a veritable gold mine of information relating to ansi, iso, federal government participation and representatim,1 in the standards process, and the role of nbs itself. fips 12-1 is available from the superintendent of documents, u.s. g.p.o., washington, dc 20402 (sd catalog no. c 13:52: 12-1). while the material above should provide a brief overview of the standards arena in which tesla will function and some insight into the scope of standards activities, it is not to be construed as a definitive compilation of standards organizations. as indicated earlier, over 2,000 such organizations are known to be active currently. iso/tc97 computers aiid ill formation processing usa sci sc2 sc3 sc4 sc 5 sc 6 sc7 s c8 'igk character character program lung digital data problem numerical data

34 abstract since the passage of the american disabilities act in 1990 and the coincident growth of the internet, academic libraries have worked to provide electronic resources and services that are accessible to all patrons. special collections are increasingly being added to these web-based library resources, and they must meet the same accessibility standards. the recent popularity surge of web 2.0 technology, social media sites, and mobile devices has brought greater awareness about the challenges faced by those who use assistive technology for visual disabilities. this study examines the screen-reader accessibility of online special collections finding aids at 68 public us colleges and universities in the association of research libraries. introduction university students and faculty today expect some degree of online access to most library resources. special collections libraries are no exception, and researchers now have access to troves of digitized finding aids and original materials at university library websites nationwide. as part of the websites of higher education institutions, these resources must be accessible to patrons with disabilities. section 504 of the rehabilitation act of 1973 first prohibited exclusion of the disabled from programs and activities of public entities, and the 1990 americans with disabilities act (ada) mandated accessibility of public services and facilities. section 508 of the rehabilitation act, as amended by the workforce investment act of 1998, also requires accessibility of federally funded services. since the passage of these laws, libraries at us colleges and universities have made progress in physical and electronic accessibility for the disabled. according to the employment and disability institute at cornell university, 2.1 percent of noninstitutionalized persons in the united states in 2010 had a visual disability.1 the us census bureau counted nearly 8.1 million people (3.3 percent) who reported difficulty seeing and 2 million who are blind or unable to see.2 these numbers indicate that there are students, faculty, and patrons outside the academic community with visual impairments who are potential consumers of online special collections materials. as ada improvements increasingly pave the way for greater enrollment numbers of students with visual impairments, libraries must anticipate these students’ need for fully accessible information resources. kristina southwell (klsouthwell@ou.edu) is associate professor of bibliography and assistant curator at the western history collections, university of oklahoma, norman, ok. jacquelyn slater (jdslater@ou.edu) is assistant professor of bibliography and librarian at the western history collections, university of oklahoma, norman, ok. mailto:klsouthwell@ou.edu mailto:jdslater@ou.edu an evaluation of finding aid accessibility for screen readers | southwell and slater 35 library websites and the constantly changing resources they offer must be regularly evaluated for compatibility with screen readers and other accessibility technologies to ensure access. perhaps because special collections materials are relatively late arrivals to the internet, their accessibility has not received as much attention as more traditional library offerings like published books and periodicals. the goal of this study is to determine whether a sampling of special collections finding aids available on public us college and university library websites are accessible to patrons using screen readers. internet access and screen readers blind and low-vision internet users have various types of assistive technology available to them. these include screen readers with text-to-speech synthesizers, refreshable braille displays, text enlargement, screen magnification software, and nongraphical browsers. guidelines for making websites accessible via assistive technology are available from the w3c’s web content accessibility guidelines (wcag 2.0).3 these rules provide success criteria for levels a, aa, and aaa for web developers to meet. many websites today still do not conform to these guidelines, and barriers to access persist. screen-reader users access information on the internet differently than sighted persons. the keyboard usually replaces the monitor and mouse as the primary computer interface. webpage content is spoken aloud in a strictly linear order, which may differ from the visual order on screen. instead of visually scanning the page to look for the desired content, screen-reader users can use the “find” or “search” function to look for something specific or use one of several options for skimming the page via keyboard shortcuts. these shortcuts, which vary by screen reader, allow navigation to the available links, headings, aria landmarks, frames, paragraphs, and other elements of the page. a recent webaim survey of screen-reader users indicated 60.8 percent navigated lengthy webpages first by their headings. using the “find” feature was the second most common method (16.6 percent), followed by navigation with links (13.2 percent) and aria landmarks (2.3 percent). only 7.0 percent reported reading through a long website without using navigational shortcuts.4 some websites also offer a “skip navigation link” at the beginning of a page, which allows the user to skip over the repetitive navigational information in the banner to hear the “main content” as soon as possible. these fundamental differences in the way screenreader users access internet content are the key to making websites that work well with assistive technology. literature review accessibility studies of library web sites in higher education have primarily focused on the library’s homepage and its resources and services. more than a decade ago, lilly and van fleet and spindler determined only 40 percent and 42 percent, respectively, of academic library homepages were rated accessible using bobby accessibility testing software.5 a series of similar studies followed by schmetzke and comeaux and schmetzke, which found accessibility rates of library homepages fluctuating over time, decreasing from a 2001 rate of 59 percent to 51 percent in 2002, information technology and libraries | september 2013 36 and rising back to 60 percent in 2006.6 providenti and zai iii examined academic library homepages in kentucky, comparing data from 2003 and 2007. they also found low accessibility rates with minimal improvement in four years.7 many accessibility studies have focused on one of the mainstays of academic library sites: databases of e-journals. early studies by coonin, riley, horwath, and others found significant accessibility barriers in most electronic content providers’ databases.8 problems ranged from missing and unclear alternative text to inaccessible journal pdfs saved as images instead of text. as awareness of web accessibility in library resources spread, research studies began to find that most databases were section 508 compliant but still lacked user-friendliness for users of assistive technology.9 more recent studies examined the actual usability of journal databases and the challenges they pose for the disabled. power and labeau still found vendor databases that were not section 508 compliant and others that were minimally compliant but lacked functionality.10 dermody and majekodunmi found that students were hindered by advanced database features intended to improve general users’ experiences.11 disabled students were also confronted with excessive links, unreadable links, and inaccessible pdfs. related studies have focused on providing guidelines for accessible library web design and services. brophy and craven highlighted the importance of universal design in library sites because of the ever-increasing complexity of web-based media.12 vandenbark provided a clear explanation of us regulations and standards for accessible design and outlined basic principles of good design and how to achieve it.13 recent works by samson and willis addressed best practices for reference and general library services to disabled patrons. samson found no consistent set of best practices between eight academic libraries studied, noting that five of the eight based their services on reactions to individual complaints instead of using a broader, proactive approach.14 willis followed up on a 1996 study by surveying technology and physical-access issues for the disabled in academic health sciences libraries. she found improvements in physical access, but technological access proved to be a mixed bag. while library catalogs were more accessible because they were available online, library webpages continued to pose problems for the disabled. significant deficiencies in the provision of alternative text and accessible media formats were observed.15 finding no comparable evaluations of special collections resources, in 2011 we examined the screen-reader accessibility of digitized textual materials from the special collections departments of us academic library websites.16 our study found that 42 percent of the digitized items were accessible by screen reader, while 58 percent were not. published at the same time, lora j. davis’ 2012 study evaluated accessibility of philadelphia area consortium of special collections libraries (pacscl) member libraries’ special collections websites and compared their performance to popular sites such as facebook, wikipedia, and youtube. davis found that the special collections sites had error rates comparable to the popular sites, but demonstrated that a low number of error codes in automatic checkers does not necessarily mean the page is usable for nonsighted people.17 davis concluded that it is difficult to “meaningfully assess site accessibility” an evaluation of finding aid accessibility for screen readers | southwell and slater 37 using only automatic accessibility checkers.18 our current research study addresses this issue by incorporating manual tests of the special collections finding aids we examined. the results provide some insight into the screen-reader user’s experience with these materials. method the researchers evaluated a single online finding aid from the websites of each of the 68 us public university and college libraries in the association of research libraries. they were analyzed with automated and manual tests during the 2012 fall academic semester. the evaluated finding aids were randomly selected from each library’s manuscripts and archives collections. selection was limited to only collections that have a container list describing manuscript or archives contents at least at box level. evaluations were performed on the default display mode of the selected finding aids. if the library’s website required a format choice instead of a default display (such as html or pdf) the html version was selected. the automated web-accessibility checker wave 5.0 by webaim was used to perform an initial assessment of each finding aid’s conformance to section 508 and wcag 2.0 guidelines. the wavegenerated report for each finding aid was used to compile a list of codes for the standard wave categories: errors, alerts, features, structural elements, and wai-aria landmarks. we recorded how many libraries earned each type of code, as well as how many times each code was generated during the entire evaluation process. manual testing of each finding aid was performed with the webbie 3 web browser, a text-only browser for the blind and visually impaired. webbie’s ctrl-h and ctrl-l commands were used to examine the headings and links available on each finding aid to determine whether patrons who use screen readers could navigate the finding aid by using its headings or internal links. the study concluded with a manual test by screen reader directed by keyboard navigation. system access to go (satogo) and nvda were used for this test. results overview basic descriptive data recorded during the selection process shows that 65 of the 68 finding aids tested were displayed as webpages using html, xhtml, or xml coding. the remaining three finding aids were displayed only in pdf, with no other viewing option available. only 25 of 68 finding aids were offered in multiple viewing formats, while 43 were only available in a single format. twenty of the finding aids were displayed in a state or regional database, while four used archon, one used contentdm, and four used dlxs. wave 5.0 web accessibility evaluation tool the three finding aids available only in pdf cannot be checked in wave, which is limited to webpages. therefore 65 finding aids were evaluated with this tool. the results show that the majority of tested finding aids (58 of 65, or 89.23 percent) had at least one accessibility error (see information technology and libraries | september 2013 38 table 1). the most common errors were missing document language, missing alternative text, missing form labels, and linked images missing alternative text. only seven of the finding aids had zero accessibility error codes. missing document language was noted for 63 percent of finding aids. language identification is important for screen readers or any text-to-speech applications, and it is a basic level a conformance requirement to meet wcag 2.0 criteria. the finding aids tested for this study contain primarily english materials, but they also describe materials in other languages, particularly spanish and french manuscript and book titles. without language identification, these words are spoken incorrectly with english pronunciation. furthermore, increasing popularity of mobile devices with voicing capabilities will likely make language identification helpful for many users, whether or not they use a screen reader for a disability accommodation. error

found for missing alternative text (36 instances at 15 libraries), linked images missing alternative text (28 instances at 12 libraries), and image map areas missing alternative text (two instances at two libraries) is surprising. alternative text for graphic items is one of the most basic and well-known accessibility features that can be implemented. the fact that it has not been provided when needed in more than a dozen finding aids suggests that these libraries have not performed the most rudimentary accessibility checks. missing or empty form labels and empty buttons, found at 24 libraries, can cause significant problems for screen-reader users. form labels and buttons allow listeners to identify and interact with forms such as search boxes. lack of accessible descriptive information makes them challenging to use, if not impossible. because headings are used with screen readers to facilitate quick keyboard navigation of a page, the presence of empty headings deprives screen-reader users of the information they need to scan the page the way a sighted patron does. similarly, skip links are used to jump to the main content of a page, bypassing the repetitive information in headers and sidebars. broken skip links were an evaluation of finding aid accessibility for screen readers | southwell and slater 39 present at four libraries, eliminating their intended advantage. missing or uninformative page titles were found at seven libraries, six of which were from pages using frames for display. when frames are used, each frame must have a clear title so listeners can choose the correct frame to hear. wave’s alerts category identifies items that have the potential to cause accessibility issues, particularly when not implemented properly (see table 2). a total of 43 percent of the finding aids reported missing first level headings, 30 percent had a skipped heading level, and nearly 17 percent had no heading structure. missing and disordered headings cause confusion when screenreader users try to navigate a page with them. listeners may think they have missed a heading, or they may have difficulty understanding the order and relationship of the page’s sections. alert number of libraries total number of occurrences accesskey 3 15 broken same-page link 9 18 link to pdf document 3 5 missing fieldset 1 1 missing first level heading 28 28

alternative text (1,071 instances at nine libraries), and redundant title text (1,093 instances information technology and libraries | september 2013 40 at 18 libraries). on closer inspection, it is clear the vast majority of these alerts came from just three libraries using archon and are due to the inclusion of an “add to your cart” linked arrow image at the end of each described item. this repetitive statement is read aloud by the screen reader, making for a tedious listening experience. redundant links accounted for the next largest group of errors (264 instances at 26 libraries). most of these came from a single library using contentdm. its finding aid included a large number of subject headings linked to a “refine your search” option. excessive links clutter the navigational structure used by screen readers. broken same page links, present on nine finding aids, also hamper quick navigation within a page. other alerts reported at several libraries indicated failure to provide descriptive information or adequate alternative text for form labels, table captions, fieldsets, and links. the presence of these problems underscores the fact that descriptive information needed by screen reader users is not reliably available in finding aids. the remaining alerts for accesskey, tabindex, plugin, noscript element, and link to pdf document simply highlight areas that should be checked for correct implementation and do not confirm the presence of an access barrier. the features, structural elements, and wai-aria landmarks codes in wave identify the coding elements that make online content more accessible. features help users with disabilities interact with the page and read all of the available information on it, such as alternative text for images and form labels (see table 3). fully 83 percent (54 of 65) of library finding aids evaluated included at least one accessibility feature. the most commonly used features are alternative text and linked images with alternative text. a total of 53 libraries used some form of alternative text. wave reported that skip navigation links were available on only four finding aids, accounting for just 6 percent of

followed by manual tests. the two added libraries raise the total to just 9 percent of libraries with skip links. considering the value of skip links to users of assistive technology, it is unfortunate they are not present on more pages. the structural elements noted by wave are the elements that help with keyboard navigation of the page and contextualizing layout-based information, such as tables or lists (see table 4). most libraries (64 of 65, or 98 percent) used at least one structural feature on their finding aids. lists and heading levels 2 and 3 are the most frequently used, followed by heading levels 1 and 4. although heading levels should be ordered sequentially to provide logical structure to the document, heading level 1 was skipped at 28 libraries (see table 2). table header cells, included at the 9 libraries using data tables to display container lists, are key to making tables screen-reader accessible. inline frames were used at seven libraries, as opposed to six libraries that used traditional frames. while inline frames are considered more accessible than traditional frames, using css is preferable to using either type. structural element number of

areas of the page such as “banner” or “search.” they serve as navigational aids for assistive technology users in a manner similar to headings. only one of the finding aids included three wai-aria roles. while aria landmarks are becoming more common on the internet in general, the data collected for this study indicates they have not yet been incorporated into library finding aids. information technology and libraries | september 2013 42 webbie 3 text browser analysis because screen reader users often use a webpage’s headings and links for navigating by keyboard commands, their importance to accessibility cannot be overstated. a quick check of any page in a nongraphical browser will reveal the page’s linear structure and reading order as handled by a screen reader. a text-only view of a website shows the order of headings and links within the document. webbie 3’s ctrl-h and ctrl-l commands were used to evaluate the 65 finding aids for the presence of headings and links for internal navigation. finding aids were rated on a pass/fail basis in three categories: • presence of any headings • presence of headings for navigating to another key part of the finding aid (e.g., container list) • presence of internal links for navigating to another key part of the finding aid headings/links yes no finding aid has at least one heading 59 (91%) 6 (9%) headings are used for navigation within finding aid 44 (68%) 21 (32%) links are used for navigation within finding aid 37 (57%) 28 (43%) headings and/or links used for navigation within finding aid 49 (75%) 16 (25%) table 5. use of headings and links for navigation (n = 65). while 91 percent had at least one heading, just 68 percent actually had headings that enabled navigation to another important section of the document, such as the container list. that means one-third of all finding aids encountered during this study could not be navigated by headings. even those that did have enough headings with which to navigate did not always have the headings in proper sequential order, or were missing first-level headings. this lack of adequate structure, given the length of some manuscript-collection finding aids, can make reading them with a screen reader tedious. finding aids with few or no headings prevent users of assistive technology from conveniently moving between sections, as a sighted reader can by visually scanning the page and selecting a relevant portion to read. even fewer finding aids offered links for navigating between sections of the finding aid. while 57 percent included such links, 43 percent did not. a total of 25 percent of pages tested lacked both headings and links of any kind for navigation within the finding aid. inclusion of headings or links to the standard sections of the finding aid facilitates keyboard navigation. additional headings or links to individual series or boxes provide even more options an evaluation of finding aid accessibility for screen readers | southwell and slater 43 for screen reader users. this is particularly helpful for patrons whose queries aren’t easily found using a search function – for example, when a patron does not know the specific terms to use for searching. only the most patient visitor will listen to an entire finding aid being read. screen reader test a manual screen reader test of each finding aid was completed by the researchers with satogo and nvda. both screen readers were used to ensure that success or failure to read the content was not because of any particular screen reader software. despite the 89 percent error rate noted by the automatic accessibility checker, the screen readers were able to read the main content of all 65 finding aids. the three pdf-only finding aids in the original group of 68 were also tested by opening them with the screen reader and adobe reader together. adobe reader indicated all three lacked tagging for structure and attempted to prepare them for reading. this resulted in all three being read aloud by the screen reader, but only one of the three was navigable by linked sections of the finding aid. the remaining two finding aids had no headings or links. while it is encouraging that the main content of all 68 finding aids could be read, some functioned poorly because of how the information is organized and displayed. finding aids serve as reference works for researchers and as internal record-keeping documents for the history of the collection. as such, they typically have a substantial amount of administrative information positioned at the beginning. biographical, acquisition, and scope and content notes are common, as are processing details and subject headings. sighted users can glance at the administrative information and skip to the collection summary or container list as needed. screenreader users can bypass this administrative information by using headings or links when they are supplied. users of the one-third of finding aids in this study that lacked these shortcuts must skim, search, or read the entire finding aid. inclusion of extensive administrative information without providing the means to skip past it creates a significant usability barrier. the descriptive style and display format of the container list also posed problems during this test. lengthy container lists displayed in tables are difficult to understand when spoken because tables are read row-by-row. this separates the descriptive table header cells, such as “box” and “folder” from the related information in the rows and columns below. as a result, the screen reader says “one, fifteen” before the description of the item in box 1, folder 15. it is hard to follow a long table, and the listener must remember or revisit the column and row headers to make sense of the descriptions. most screen readers have a table-reading mode for data tables that will read the header cell with the associated content, but only if the table has been marked up with sufficient tags. container-list-item descriptions that begin with an identification number or numeric date (e.g., 2012/01/13) are particularly unclear for listeners. these long sequences of numbers seem out of context when spoken by the screen reader, and it can be difficult to infer the relationship between the number and the item. item descriptions that are phrased as brief sentences in plain language result in finding aids that are more easily understood. application of findings information technology and libraries | september 2013 44 most special collections personnel in academic libraries are not responsible for the design of their websites, which are part of a larger organization that serves other needs. it is important that special collections librarians communicate to administrative and systems personnel that finding aids must be accessible to the visually disabled. libraries cannot rely on a content management system’s claims of being section 508-compliant to ensure accessibility, because that does not automatically guarantee the information displayed in the system is accessible. proper implementation of any content management system’s accessibility features is a key factor in achieving accessibility. librarians can take the first step toward improving accessibility of their special collections’ online finding aids by experiencing firsthand what screen reader users encounter when they use them. this can be done by conducting the same automated and manual tests described in this study. the following key checkpoints should be considered: accessible finding aids should • be keyboard navigation-friendly; • include alternative text for all graphics; • have descriptive labels and titles for all interactive elements like forms; • offer at least one type of navigational structure: o skip links and internal navigation links, o sufficient and properly ordered headings, or o wai-aria landmarks; and • linear reading order should be correct and simulate visual reading order, particularly for the container list. conclusion this study indicates that special collections finding aids at us public colleges and universities can be accessed by screen-reader users, but they do not always perform well because of faulty coding and inadequate use of headings or links for keyboard navigation. it is clear that many finding aids available online today have not been evaluated for optimal performance with assistive technology. this results in usability barriers for visually impaired patrons. special collections librarians can help ensure their electronic finding aids are accessible to screen-reader users by conducting automatic and manual tests that focus on usability. the test results can be used to initiate changes that will result in finding aids that are accessible to all users. an evaluation of finding aid accessibility for screen readers | southwell and slater 45 references 1. “disability statistics,” employment and disability institute,

technology and libraries | june 2017 59 abstract like many academic libraries, the ferris library for information, technology, and education (flite) acquires a range of materials, including learning objects, to best suit our students’ needs. some of these objects, such as the educational manipulatives and anatomical models, are common to academic libraries but others, such as the tabletop games, are not. after our liaison to the school of education discovered some accessibility issues with innovative interfaces' media management module, we decided to examine all three of our realia collections to determine what our goals in providing catalog records and visual representations would be. once we concluded that we needed photographic previews to both enhance discovery and speed circulation service, choosing processing methods for each collection became much easier. this article will discuss how we created enhanced records for all three realia collections including custom metadata, links to additional materials, and photographic previews. introduction ferris state university’s full-time enrollment for fall 2015 was 14,715 students. of these students, 10,216 are big rapids residents and the other 4,499 are either kendall college of art and design students or at other off-campus sites across michigan.1 during the 2014-2015 school year, flite had 14,647 check-outs including 2,558 check-outs of items in reserves, which is where our realia collections are located.2 however, reserves includes other items in addition to these collections, thus making analysis of circulation statistics problematic. another problem with conducting such an analysis is that the educational manipulative collection already had photographic previews and the tabletop game collection is a pilot project, so there is no clear before and after comparison. we can, however, demonstrate that enhancing the catalog records for our anatomical model collection had an incredibly significant impact, jumping from a handful of check-outs from 2014-2015 to almost 450 in 2016. literature review although there are very few libraries using photographic previews for their realia collections, the ones that do described similar limitations with bibliographic records and goals that only dejah t .rubel (rubeld@ferris.edu) is the metadata and electronic resources management librarian, ferris state university, big rapids, mi. picture perfect: using photographic previews to enhance realia collections for library patrons and staff | rubel | https://doi.org/10.6017/ital.v36i2.9474 60 photographic previews could meet. most realia collections that warranted this extra effort are either curriculum materials or anatomical models, which is not surprising considering how difficult they are to describe. as butler and kvenild noted in their article on cataloging curriculum materials, “patrons struggled to identify which game or kit they sought based on the…information in the online catalog,” because “discovering curriculum materials in the catalog and getting a sense of the item are not easy when using traditional catalog descriptions...”3. as they continue, “the inventory and retrieval problems…were compounded by the fact that existing catalog records were not as descriptive as they should be.”4 this was also a problem for our collections because our names and descriptions were often not intuitive or precise. in addition, as loesch and deyrup discovered while cataloging their curriculum materials collection, “…there was great inconsistency among the oclc records regarding the labeling of the format…,”5 which was another issue we needed to address. although the general material designation (gmd) has since been rendered obsolete, flite continues to use it to highlight certain material. this choice is due to some limitations with our library management system as well as our discovery layer, namely the lack of good mapping or use of the 33x fields. until this is rectified with a more modern system, we have it found it easier to retain certain gmds like “sound recording”, “electronic resource”, and “realia”. thus, we needed to standardize our terms for each collection. another problem that our predecessors indicated photographic previews might resolve was missing objects or pieces of objects.6 this becomes especially important for our tabletop games collection because most of those pieces are very small and too numerous for a piece count upon return. fortunately, “previews…can aid users in making better decisions about potential relevance, and extract gist more accurately and rapidly than traditional hit lists provided by search engines.”7 ideally, a preview will display an appropriate level of information about the object it represents in order “…to support users in making a correct judgement about the relevance of that object to the user’s information need.”8 greene goes further by listing the main roles for previews of which the first two are the most applicable for photographic previews: aiding retrieval and aiding users in quickly making relevance decisions.9 for these uses, photographic previews of realia are ideal because users can examine the object without needing to see its details and they expect them to be abstract, not exhaustive, unlike digital surrogates that an archive would use.10 as greene also notes, the high-level goal of any preview is to "...communicate the level and scope of objects to users so that comprehension is maximized and disorientation is minimized."11 a common finding among all the previous projects was that even a single photograph provides more readily comprehensible information than several lines of description. as moeller states regarding their journal project, "they [previews of each issue's cover] give the researcher or student an immediate idea of the nature of the journal."12 he goes further to give the example of an innocuous journal title for a propagandist serial whose political nature is transparent once you view its imagery. from a staff perspective, photographic previews can also easily illustrate the number of information technology and libraries | june 2017 61 pieces and an object's condition or orientation. this can be very useful in determining whether something is missing or damaged without having to do a time-consuming individual piece count upon check-in. but as butler and kvenild discuss, layout within each photograph is key for illustrating missing pieces.13 unfortunately, aside from a few small projects mentioned in butler and kvenild's article, there are not many examples of photographic previews for realia collections currently being used by academic libraries. one reason might be software limitations. innovative's media management module is still unique among ils/lms software in that most vendors either provide a separate digital repository for special collections digital surrogates or they incorporate images into the catalog using third party software like syndetic solutionstm. another reason for the lack of photographic previews within catalogs may simply be the rarity of realia in academic libraries. every library certainly has a few unique pieces, like a skeleton for the pre-medical students, but often not enough to consider them an entire collection much less a complex enough collection to warrant the extra effort to create photographic previews of each item. at flite, we had already crossed that threshold of complexity. therefore, this article will start by discussing our educational manipulative collection, which provided the basis for how we would catalog and process the tabletop games and anatomical models. educational manipulative collection our first foray into creating photographic previews was completed by the previous cataloger with over 300 items cataloged in 2004 and another 30-40 added to the collection over the next decade. unlike the other realia collections, the educational manipulatives were cataloged using innovative’s course reserves module, so no attempt was made to find or create oclc records. nevertheless, the minimal metadata is very consistent across the collection, which supports greene’s recommendation “…that it was important to define a set of consistent attributes at the high level of the collection if any effective browsing across the collections was to be provided.”14 in our case, we rely on a combination of the gmd ([realia]), a custom call number prefix (toys box #), and a limited amount of local subject headings as shown below with “manipulatives” as the common subject for the entire collection. 690 = (d) current local subject headings in use as of 12/3/15: art. infant/toddler. block props. magnets. boards. manipulatives. cognitive. music. discovery box. oversize books. discovery. posters. dramatics. puppets. finger puppets. story apron. flannel board. story props. gross motor. woodworking. picture perfect: using photographic previews to enhance realia collections for library patrons and staff | rubel | https://doi.org/10.6017/ital.v36i2.9474 62 due to the nature of descriptive metadata, photographic previews of the educational manipulatives made logical sense because “the images…are not the content. they are the metadata, the description of the materials.”15 as moeller describes, innovative’s media management module links images and many other file types directly to bibliographic records without requiring users to click an additional link unless they want to view a larger image of a thumbnail.16 similar to butler and kvenild’s project, all of our photos were 900 pixels wide by 600 pixels tall, which is slightly smaller than their default width of 1000 pixels.17 one advantage of using the media management module is its ability to automatically create thumbnails 185 pixels wide by 85 pixels tall. a bigger advantage is that the images are hosted on the same server that runs our catalog, which allows us to freely distribute the images in an intuitive manner (thumbnails instead of links) without having to worry about authentication to a shared folder from off-campus, unlike our pdf files. unfortunately, our liaison to the school of education recently discovered some accessibility issues with media management that forced us to consider whether we should change the embedded photographic previews to external links. the most significant of these problems is simply the language of the proprietary viewer software. because it is written in java, if you click on a thumbnail for a larger image, many browsers, like chrome, will not run it and those that will often require a security exception to do so. we have attempted to ameliorate some of these issues by providing an faq entry on which browsers are best for viewing these images and how to add a security exception for our website, but unless or until innovative rewrites this software in a different language, these accessibility issues will persist because java is being phased out of many browsers. butler and kvenild also noted its slow response time compared to their own server.18 another issue they mentioned was that the thumbnails would not be visible in their consortial catalog, so they needed to add links in the 856 field for these users.19 this is less of an issue for us because we do not contribute any of our realia records to our consortia catalog, but moeller’s concern that in general “…enhancements involving scanned images…will not be easily shared with other libraries,”20 is entirely valid. unlike oclc records, there is no way to share attached or embedded images as part of the metadata and not the content. contrariwise, butler and kvenild’s concerns regarding catalog migration are very pertinent because we are considering moving to a new lms within the next few years.21 although we acknowledge that “utilizing 856 tags is an indirect method of accessing the images, as users must take the intiative to follow the links,” we will eventually have to move and link our photographic previews to ensure accessibility after migration.22 tabletop game collection unlike the educational manipulatives, the majority of the tabletop game collection was previously cataloged in oclc, so finding good bibliographic records was easy. once downloaded, we decided to add a unique gmd ([game]), custom call number prefix (board game box #), and local subject heading “tabletop games”. however, our emerging technlogies librarian who coordinated this information technology and libraries | june 2017 63 pilot project felt that the single subject heading was not descriptive enough. so he gave us a spreadsheet with more specific subject headings such as “deck building”, “historical”, and “resource management” that we added as genre/form subject headings in the 655_4 field. he also suggested that we add links to the rule books, which we did using the 856 field and the link text “connect to rule book (pdf)”. because tabletop games are commercial products, finding images online was also easy. at first, we had some concerns about copyright, but we are not reselling these products or using the image as a replacement for the item. so, we concurred with butler and kvenild that “…the images in our project fall under copyright fair use.”23 another plus to using commercial images is that we could use more than one to show various aspects of setup and play. the downside to this benefit is image sizes and content photographed varied widely, so we used our best judgement in creating labels and tried to keep them as consistent as possible. to ensure consistency across the collection, we decided that the first image should always be the top of the game’s box labeled “box cover” or “box cover – front” if there was a “box cover – back” image. (we only displayed the back of the box cover if there was significant information about the game printed on it.) then we added up to five additional images showing parts of the game like “card examples”, “game pieces”, and “game set-up”. overall, this number of images worked very well in both encore’s attached media viewer and the classic catalog/web opac, but there is a slight duplication in images by syndetic solutionstm for a few games. this results in a larger version of the box top image displaying to the right of the title and above the smaller thumbnails of images we added using media management. in regards to piece counts, we presumed that we would need photographic previews to aid in piece counting upon return of a tabletop game. however, our emerging technologies librarian assured us that because we are an educational institution, we could contact the vendor for free replacement pieces at any time. he also emphasized that unlike the educational manipulatives or the anatomical models, this was a pilot collection, so extensive processing would not be a good investment of our labor. fortunately, the anatomical model collection would require images for piece counts as well as several other cataloging customizations to increase discoverability and speed circulation. anatomical model collection similar to our educational manipulative collection, but not nearly as extensive, our anatomical model collection has been a part of flite since its inception. unlike the manipulatives, which are used primarily by the early childhood education students, the anatomical models support a range of allied health programs including but not limited to dental hygiene, radiology, and nursing. the majority of our two dozen models were purchased in the 20th century and, like the manipulatives, the majority were cataloged using innovative’s course reserves module. unfortunately, none of these records were very descriptive, some being so poor as to be merely a title like “jawbones” and a barcode. so, the first task was to match objects with oclc records. fortunately, this task picture perfect: using photographic previews to enhance realia collections for library patrons and staff | rubel | https://doi.org/10.6017/ital.v36i2.9474 64 became easier once we discovered that it was easier to match the object to the vendor’s catalog image and then search oclc by vendor model name or number than it is to decipher written descriptions if you do not know human anatomy. once good bibliographic records were downloaded, we decided to add one of three gmds depending on the type of model ([model], [chart], or [flash card]), a custom call number prefix (model #), and one or more of the local subject headings shown below. 690 = (d) anatomy model. anatomy chart. anatomy models. anatomy charts. dental hygiene model. dental model. dental hygiene models. dental models. technically, all dental models could be used as anatomical models, but not vice versa. therefore, the common subject headings for the collection are “anatomy model” and “anatomy models”. to make things easier to shelve, retrieve, and inventory, we also designed numeric ranges for the call numbers, as shown below, so we would know what type of model we should expect when referring to a specific model number. 099 = (c) model #00x following this hierarchy: 001-099 anatomical charts and flash cards 100-199 articulated skeletons 200-299 disarticulated skeletons and bone kits 300-399 organs 400-499 skulls (anatomical and dental hygiene) 500-599 other dental models (dental studies, dental decks) we also scanned and linked pdfs of the heavily worn model keys with the link text “connect to key pdf” before washing and rehousing all the models. once they were clean, they were ready for their shoot with ferris state university’s media production team. due to winter break, media production was able to shoot the majority of the collection fairly quickly. they returned to us high-resolution tiffs the same size as those for the manipulatives, 900 pixels by 600 pixels. in case of java viewer failure, we requested that there be one top-level image that showcases exactly what the model contains with images of individual pieces or drawers as the succeeding images. for example, our disarticulated skeletons are housed in small plastic carts with three drawers in each cart. therefore, the first image would be a shot of all the pieces of the disarticulated skeleton and the second image would be the contents of the top drawer, the third image the contents of the middle drawer, and the last image the contents of the bottom drawer. in this specific example, we re-used the images that we posted in the catalog information technology and libraries | june 2017 65 record by pasting them on top of the cart to show circulation staff what to expect in each drawer upon check-in. overall, photographic previews for this collection appear to be working very well for both catalog users and circulation staff “…to inform users about size, extent, and availability of collections or objects.”24 in fact, they have been working so well for this collection that usage has increased exponentially compared to previous years. figure 1. circulation statistics 2014-2016 conclusions and future directions although we implemented photographic previews for three realia collections, we could not define any standard workflow for the process beyond correcting or downloading the metadata first and adding the images second. part of this is due to our working primarily with legacy collections because we often discovered issues, like the model keys, while working through another issue. the other part is due to the nuances involved in processing realia in general. even with good, readily available catalog records like those for the tabletop games, time still had to be spent separating, organizing, and rehousing game pieces as well as hunting down useful images. unfortunately, any type of realia processing, even if it is just textual description, is much more time-consuming than the majority of academic library cataloging. adding in the extra steps to create, upload, and link a photographic preview can nearly double that labor investment. notwithstanding, as butler and kvenild advocate “…not supplying images as metadata for items that most need them (i.e. kits, games, and models) is to make them nearly irretrievable. providing bare-bones traditional metadata for these items is analogous to delegating them to the backlog shelves of yesteryear.”25 367

for library patrons and staff | rubel | https://doi.org/10.6017/ital.v36i2.9474 66 unfortunately, neither the library management system nor the third-party catalog enhancement market currently provides a good solution to this problem. considering how great an impact photographic previews have had in the online retail market, this lack of technical support is surprising. yes, syndetic solutionstm is a great product for cover images and tables of content for books. however, once you go beyond traditional resources, there is a great need to allow institutions to submit their own images as part of catalog record enhancement and not to serve as separate digital surrogates in a digital respository. this could be done either within the library management system, like the media management module, or as an option for catalog enhancement where libraries could add images to either a shared database or their own database using standard identifiers on a third-party platform like syndeticstm. further research on photographic previews is also sorely needed. as of this writing, we only have a handful of case studies and some guiding philosophy on the use of previews. consultation with internet retailers and literature on online marketing might be more applicable than library science research to evaluate their impact, but research into their direct impact vs. textual descriptions on catalog use would be ideal. references 1. fact book 2015 – 2016 (big rapids, mi: ferris state university institutional research & testing, 2016),

management: ... northrup, lori;cherry, ed;darby, della information technology and libraries; dec 2004; 23, 4; proquest pg. 192 tutorial using server-side include commands for subject webpage management: an alternative to database-driven technologies for the smaller academic library lori northrup, ed cherry, and della darby frustrated by the time-consuming process of updating subject web pages, librarians at samford university library (sul) developed a process for streamlining updates using server-side include (sst) commands. they created text files on the library server that corresponded to each of 143 online resources. include commands within the html document for each subject page refer to these text files, which are pulled into the page as it loads on the user's browser. for the user, the process is seamless. for librarians, time spent in updating web pages is greatly reduced; changes to text files on the server result in simultaneous changes to the edited resources across the library's web site. for small libraries with limited online resources, this process may provide an elegant solution to an ongoing problem. the migration of print ed subject guides and p athfinders to web pages began almost concurrently with th e creation of library web sites. dunsmore relates that this online mi gra tion durlori northrup (lanorthr@samford.edu) is reference librarian, ed cherry (cecherry @samford.edu) is the automation librarian, and della darby (dhdarby@samford. edu) is the coordinator of reference and government documents at samford university library, birmingham, alabama. in g the 1990s was follow ed almost immediately by articles on the d esig n, construction, usability , and maintenanc e of web-ba sed subject guides. 1 a scan of recent literat ure (for example, dean; roberts; davi dson; grimes and morris; and galvanestrada) suggests that onlin e access to library resources has becom e the norm, and that librarian s struggle with the tim e necessary to maintain th ese guides online. 2 in an effort to reduce time sp en t maintainin g subject guides to int erne t, print, and online resources, librari ans are discove ring more efficient methods of resource management for their web-mounted subject guid es and pathfinder s. roberts , davidson, and ga lvanestrada d escr ibed variations of database-driv en technology th at generate dynamic subject guides to library res ources; a common database of reso urces that have been descriptive ly enhanced for retrieval pro v ides the backbone for a system th at crea tes subject guid es for the user at the point of query. ' patrons can then search for materials that ma y cross disciplinary lines, and receive a more targeted result list than the y would ha v e rece ived had they only combined two s tatic subject bibliographi es from related fields. the primary advantage to this type of retrieval system , for the librarian, is that updates can be done at one central location-within the database-and will then appear when the upd ated item is viewed on any portion of the library 's web site generated from that database . libraries that have adopted databa se-driven technologies hav e done so because their resource listings have exceeded m anageable capacity. selected resourc es from the int erne t or from librar y electronic holdin gs have reached a numb er that is difficult for available staff to maintain , especially acro ss hundr eds of static web pages. for one library , this might mean a collection of mor e than two hundred; for larger librar y, this critical point might be reached only after eight hundred resources were gathered. at some 192 information technology and libraries i december 2004 point in the collection of resourc es, the amount of work n ecessa ry to create a database-driven syste m will be less than the pot en tial workload for updating individual pages. for the creat ors of these databasedri ven systems of resource retri eva l and displa y, th e time inve sted in the database sys tem grea tly outweighs th e potential time lost in upd ating what davidson has describ ed as "hundreds of p ages of html containing multipl e occurrences of the same information , each of which nee ds to be checked and updat ed in response to even trivial changes in title or url." 4 however, the investm ent of time and labor neces sary to th e creation of a populated database should not be downplayed. davidson also notes "th e process of recrea ting or migrating an entire site to a databa se-driven platform is timeand lab or -intensive ."5 indeed, rob er ts sugg es ts that the labor and time required of library staff to get the sys tem running at full potenti al outweighs any technical issues involved in creating th e database. 6 in galvanestrada 's case, librarians created tools spe cific to the sys tem to facilitate entr y of dat abase information , th ereby incr easi ng initial time and lab or investm ents. 7 this method for handling a multiplicity of web pages and resources may work well for colleges and universities with hundreds of resources to be repeated across searche s or subject pages. for some libraries , howeve r, the critical amount of resources tha t can spur tha t type of d ecision ma y never be reached. a closer loo k at one small acad emic library 's efforts to reduce time spent in updating static html subject guides may be helpful to other librari es in similar situations . samford's situation samford univ ers ity is a smallto medium-sized institution , with about 2,900 undergr aduate and 1,500 gradu ate students. the campus h as five reproduced with permission of the copyright owner. further reproduction prohibited without permission. information units: the university library, the law library, the education curriculum center, the career development center, and the drug information center. the university library is the primary information center for all disciplines except law. within the reference department, which is one of several university library departments, four full-time librarians are responsible for general reference, government documents reference, and maintenance of the department's designated web pages on the library's web site. like the majority of academic libraries, samford university library (sul) provides subject access to its electronic resources. sul' s practice is to provide static-subject web pages that include a list made up of (1) peri odical databases of primary subject importance, databases of secondary importance, and general databases; (2) reference books; and (3) web sites. each reference librarian is responsible for the creation and maintenance of selected subject pages and departmental pages. the department also maintains a page with an alphabetical list of all sul subscription databases and some free databases. it is from this list of commonly used resources that librarians select materials to fill the top portion of the subject pages . subject pages have undergone several metamorphoses in recent years. one major change was to add brief descriptions to each title on the database list while maintaining links to pages that held more in-depth information about each of the databases. because a database may be listed on two or more subject pages, these changes required a considerabl e amount of repetitious updating . the initial changes were made to the alphabetical list, and then the html code was copied into each of the subject pages where the title was listed. copying and pasting in this way helped to ensure consistency across subject pages. when a recent review of sul's web-site statistics indicated that the description pages were receiving little or no activity, the reference librarians decided to enlarge the descriptions under each database title on the list and remove the links to the description pages. this would provide more initial information for the patron while eliminating the web team's maintenance of underutilized pages. making these changes across all the sul subject pages and some other affected pages resulted in hours of html correction . for each change made to the alphabetical list of resources, several other subject web pages had to undergo the same change. for example, librarians were copying the information for academic search elite (ase) and infotrac onefile across every subject page. recently, faced with another update of all of the subject pages due to a database name change, the reference librarians decided to find a method that would minimize the repetition of effort required for this and future overhauls of the sul database lists. some informal discussion among reference librarians and with the automation librarian had concerned recent literature on database-driven web sites; however, the general consensus was that sul had neither the time nor the need to take such a significant leap. the total number of items on the alphabetical list of resources at that time was 144. adopting a new platform of operation in a database-driven model seemed too large an undertaking for sul' s small list of resources. the reference coordinator consulted with the automation librarian about the possibility of using include statements in place of each database title and description. the web team was already using include statements for the headers and footers of all library web pages. include commands include commands are a type of ssi code. fagan explains that through using ssi codes, a web author with no knowledge of programming can insert set groups of data into an html web page. carefully constructed statements within the html page give the server a command to locate and insert a piece of information (a date, a text file, a program). when a user requests a page (clicks on a link for the page), the server loads the page, inserting the requested material in place of the ssi code on the page ." the web server executes ssi code before the web page is transferred to the browser making the request. this means that the use of ssi is not browser-dependent. ssi directives work regardless of security or privacy controls in the browser, such as disabling javascript or cookies. mach notes that this type of retrieval and substitution can be especially helpful for material that is used repeatedly on several library web pages. the web author can create one file containing the information used on several pages; then, when a change is made to that file, it is repeated across all web pages that include that file. 9 as mentioned above, sul web pages all include the same header and footer; these headers and footers do not appear in the original html code for the pages . instead, there is a command that tells the server to locate the header and footer files and include them when the page is loaded on a browser. the user does not know that ssi coding was used; for the user, the page appears complete. if a change needs to be made in a footer , then the change is made to the file containing that information. changes appear on all pages that refer to the edited footer file. library literature on the use of ssi somewhat slow to adopt ssi capabilities, librarians have recently made excellent use of this elegant resource . using server-side include commands i northrup, cherry, and darby 193 reproduced with permission of the copyright owner. further reproduction prohibited without permission. current articles tend to be written with the understanding that many librarians who work on their library's web site may not have the experience or levels of access necessary to make server changes. articles focus more on the implementation of the syntax at the level of web-page maintenance and less on server technology. authors in the most recent publications have been more likely to offer examples, and to speculat e on uses that, while they are not entirely innovative, hav e not been fully taken advantage of in the past. using ssi to include text files in a web page has been mentioned as a possibility since the first article, but later articles have tended to amplify the possibilities for this type of include command. in a slight shift of emphasis, later articles have tended to downplay the added server strain that was once a matter of great concern for ssi users. ssi statements have probably been in use in libraries since servers were capable of processing them; documentation accompanying servers includes information on their use, as do some html manuals for beginning web-page creators. reference to the use of ssis in a library environment does not appear until 2000. notess's article provides a good, concise overview, and points to several helpful resources for the webmaster. notess mentions common uses of ssi commands that will provide knowledge about the page, such as "current date and tim e, the ltrl of the page, the directory in which the file is located, the kind of browser the user has, or pull in content from separate files to construct the page before it is delivered." he elaborates on this point by stating that "a simple text file can contain the content [for a web page], and people with no html experience can be given access to change that text." 10 while he mentions this possibl e use of the ssi include command for text files, notess's examples all concern the echo command. notess does mention that ssi can possibly cause server strain but states that "includes add very little extra load" [emphasis added]. 11 later articles tend to mirror notess's in describing situations appropriate for the use of ssi and in noting possible difficulties and concerns. mach's article assumes a bit more knowledge of servers and also access to server set-up features, but it is written in clear explanatory language and provides exc ellent examples of commonly used ssi commands, including figures to illustrate those uses. she elaborates on notess's suggestion about text files, and makes the suggestion that if non-html files are the targets of ssi commands, that they be given an extension such as .txt, so that they will not be indexed as web pages. 12 also notable is her assertion that "most web servers should be able to handle the extra load of parsing all files and simply using th e .html extension already in place." 13 written with an eye to those who are not web or server administrators, pagan's article one year later provides many example screen shots and a step-by-step guide to implementing ssi. the information here is similar to that in mach 's article, but the style is more accessible to the less-experienced web site developer. like mach and notess, fagan mentions the use of non-html files and clarifies the idea of having an "all-text file, which could be ftp'd to the web server." 14 as with the other authors, she mentions that enabling ssi on a server can result in the loss of "at least microseconds of time" as pages are parsed and reconstructed for the browser .15 she explained, though, that "ssi is used on large web sites in some fairly complex ways without causing any discernible time lag . the question is one of how busy your web server is; if it is not overburdened with requests, it will easily handle the additional load of parsing files." 1" she rightly asserts that slow internet connections or older, slower patron pcs are more likely to cause delays than is ssi load on a server. 17 194 information technology and libraries i december 2004 these articl es demonstrate an organic movement toward wider use of ssi capabilities. all of them mention the potential to use ssi for portions of pages that are the same, such as headers and footers. each of them also mentions the use of ssi to include text files that web authors without html experience can edit. what they do not cover is the use of ssi to include text files that are repeatedly used in the body of multiple web pag es. examples given are for web page s with significant blocks of text that might be written at different times by different authors. the use of ssi include commands at sul to insert pieces of identical text across many pages, while not groundbr eaking , is significant in light of libraries' recent efforts to handle large numbers of electronic resources. sul's experience as the literatur e and server technology have advanc ed over the last few years, there has been a noticeable move from emphasis on the strain that ssi can cause to acknowledgement that the technology has become more capable in handling that strain. this is not to say that strain on the server does not occur. the user manual for apache servers clearly states that "while this load increase is minor, in a shared server environment it can become significant." 18 however, the increases in server speed and capability certainly make it more feasible to use ssi in quantity than it was in the past, and library literature supports that view. informal information from web discussions and web-development sites is much more emphatic . recent discussion on thelist at evolt.org focused on this issue and elicited the following from baratta: "today's servers are super charged compared to just a few years ago, and most people won't see the traffic levels that give ssi overhead a chance to affect serving time." 19 reproduced with permission of the copyright owner. further reproduction prohibited without permission. the server statistics at sul bear out this theory. the library's six-yearold apache server last year averaged slightly more than 300,000 hits per month. the average increases somewhat to around 340,000 hits during the nine months of samford' s fall and spring semesters. this total number of hits includes all catalog searches as well, as this server also hosts sul' s automated library system. despite this seemingly large number of hits, the server usually reports that it is 80 percent to 90 percent idle even during the 8 a.m. to 5 p.m. time slot during which it does the major portion of its work. at the time these statistics were gathered, ssi was already in use for the inclusion of urls, last update dates, and some header and footer information. the commands directing the server to provide this information to the browser are more taxing to the server than commands employing the include command. after the addition of four to ten include commands on each of thirtyseven subject pages, and the construction of one alphabetical list consisting only of 143 include commands, the load on the server remains at less than 20 percent. this load is on a server with a 200 mhz powerpc processor, with 512 mb of ram. certainly each library has its own server situation, and this solution for handling occasional updates to electronic resources information on library web pages may not work for all. consultations with the automation librarian or computer technology department should verify specific limitations and requirements for using ssl sul also tested to see whether the use of ssi would result in longer page load times. the download of two identical (to the user) pages, one static and the other built from include directives, was timed. there was no visible difference between the two. a more rigorous test may have detected a difference measurable in milliseconds. however, sul librarians feel that the user's connection speed has a larger effect on the page load time than the use of ssl background the evolution of this process for sul moved rather quickly from inception to application, involving only slight changes to the library's normal processes for updating web pages. the most time-consuming tasks involved creating the include .txt files at the outset, and then providing a database of the completed include commands. each time a database title is added to the collection, the automation librarian creates a persistent uniform resource locator (purl) for that database. this is due to the tendency of the database vendors to alter the url through which access is gained and because the library sometimes switches vendors for its databases. with this procedure in place, the automation librarian can make the change to the url in one place and every link to that database will connect properly. this saves considerable time and effort for the librarians who maintain the subject pages. librarians were in the habit of using that purl to create a section of html that presented the database link to the patron. figure 1 illustrates a portion of html code for ebsco' s ase as it appears in a text editor. in addition to appearing in subject pages on various topics, subscription databases and commonly used web resources are listed in one alphabetical listing. this page, updated first when changes are made, is where librarians came to copy the current code for a database. in this way, sul attempted to keep pages consistent. text for a database could be copied and pasted into the html editor as a librarian worked to update the pages. while this seemed like a smooth process, the simple reality of having to copy and paste one database change to, potentially, all subject pages was too time-consuming to make it an efficient process. updates to the subject pages and alphabetical list are done as time permits. often, one or two librarians were unable to make the changes until weeks had passed, resulting in a web site that was inconsistent and sometimes misleading. for instance, dates of database coverage might change and be documented on the alphabetical list, but not on all the subject pages listing that database. the way sul does it now when it was decided to try the include commands as an alternative for updating database information and streamlining the update process for librarians, changes were made over the course of three days, and occurred in three phases. in phase one, the alphabetical list was carved into 143 individual .txt files, each of which contained information for one database or web resource. each .txt file was saved on the server with a name corresponding to the purl that is used for that database, or with an easily recognizable name constructed from the title or url of the resource. the html code in figure 1 became a .txt file titled eb-ase.txt. using the purl for the title of the file makes it more easily recognizable and acquaints librarians with the purls already in use. in phase two, one librarian created an excel file containing the following: (1) an alphabetical list of resource names; (2) existing names for the corresponding .txt files; and (3) component parts of an include command for each resource. the final column concatenates these component parts together resulting in a ready-made include command for each resource. figure 2 illustrates a portion of this table. in phase three, librarians used th e table of include commands to select the resources they wanted on thei r pages. this entailed replacing a block using server-side include commands i northrup, cherry, and darby 195 reproduced with permission of the copyright owner. further reproduction prohibited without permission. of html code with one include command . the examp le of html code in figure 1 would be reduced to the following statem ent: <!---#incl ud e vir tu al=" / top ics/ includ es/e b-ase.txt" -> once the appropriate pieces of html code had been replaced with corresponding include statements, the changeover was complete. from this point forward, changes in such things as database names, coverage periods, and descriptive material will be made to one .txt file. the change will immediately be reflected across all subject pages with no additional work involved for the librarians responsible for those pages. note that the sul server has been configured so that it parses all web pages. this is necessary because most of the library's web pages have some ssl this configuration means that the web page extensions remain .html. if the server is not configured in this manner, then all pages containing ssi must end in a .shtml extension. this is a subject that requires discussion with automation librarians or the department responsible for the library's server. advantages obviously, the biggest advantage to this method is the time saved for individual librarians. there is now no need for librarians to do any maintenance work for links to information housed in the alphabetical list. static html pages referencing gale's infotrac onefile database, for instance, would have required updates to approximately forty subject pages; now, one librarian can correct one .txt file and simultaneously update all forty subject pages. time saved can be used in collecting and editing the list of web sites that are a part of each subject page; this is a task that has been pushed back in the past, in favor of making more urgent database information changes. .! i coffeecup html editor www.coffeecup.com , f.ile j;:dit ~iew q.ocument [nsert e,ormat iools \'lindow t!elp j .

training. the creation of the excel database of include commands allows for quick additions to an existing page, or the creation of new subject pages. librarians using the include commands can simply copy and paste them; there is no need for them to understand the syntax or to be able to repeat it. this makes using ssi particularly attractive to staff who do not want the added burden of further training in html. the librarian responsible for creating the .txt files and the excel database of statements demonstrated the copying and pasting of the include statements to all the other librarians who edit html pages in a one-time tenminute training session. the only additional training issue has involved page structure. since the library uses a table structure for the subject pages, all table tags are included in the database .txt files. making sure that librarians understand that they do not need to recreate the table tags has been the only additional training issue for the department. as librarians begin to use these commands, links to resources across subject pages will look the same and will provide the user with the same information. this increased uniformity results in a more professional appearance for the web site as a whole. disadvantages this revolution in the maintenance of subject pages has not been without its disadvantages. the primary complaint by librarians using ssi include commands is that they cannot preview their changes in their html editors. sul's department uses the coffeecup html editor, which allows previews, but the previews are not visible for items that are retrieved using ssis. this is because the page is not fully assembled until the server assembles it. when the librarian views the page in the editor, 196 information technology and libraries i december 2004 reproduced with permission of the copyright owner. further reproduction prohibited without permission. prior to uploading it to th e server, the include commands are without tar gets. the target .txt files are on the server. when a user requ ests a p age, include commands pull in the missing pieces (the .txt files, or other files); th en, th e completed pag e is seamlessly presented to the us er via his or her brow ser. as mach notes, "preview ing a web page without crucial element s . . . can be di sconcerting, esp ecially to visuall y oriented d esigners."20 in sul's experienc e with thi s particular issue, librarian s who are uncomfortable loading pages with locally invisible elements can load th em into temporary fold ers on the server, check them for errors there, and then move them to th eir appro priate dir ectories . conclusion situational factors have allowed sul to imple ment this change with surprising ease and speed. because the library has its own server, and because th ere is an automation librarian on staff, communicati on and chan ge have been easy and efficient. librar y staff deduce that it is becau se the include command of ssi is b eing u sed more than other possible commands that the librar y is not experiencing an increase in loadin g tim e on its pages. of course, the size of sul's reso urce list makes this kind of soluart & tec h ebsco tion feasible ; certainly, if the librar y were working with hundreds of resources, it would be more likely that a datab ase -driv en strategy would be ad op ted . the simplicity and

librarians, technology skills, and their relationship with technology jenny emanuel information technology and libraries | september 2013 20 introduction a new generation of academic librarians, who are a part of the millennial generation born between 1982 and 2001,1 are now of the age to either be in graduate school or embarking on their careers. often referred to as “digital natives” because their generation is believed to have always grown up online and with technology ubiquitous in their daily lives,2 many agree that this generation is poised to revolutionize library services with their technology skills.3 younger academic librarians believe that their technology knowledge makes them more flexible and assertive in libraries compared to their older colleagues, and they have different ways of completing their work. they refuse to be stereotyped into the traditional “bookish” idea of librarianship and want to transform libraries into technology-enhanced spaces that meet the needs of students in the digital age, redefining librarianship.4 this paper, as part of a larger study examining millennial academic librarians, their career selection, their attitudes, and their technology skills, looks specifically at the technology skills and attitudes toward technology among a group of young librarians and library school students. the author initially wanted to learn if the increasingly high-tech nature of academic librarianship attracted millennials to the career, but results showed that they had a much more complex relationship with technology than the author assumed. literature review the literature concerning the millennial generation focuses on their use of technology in their daily lives. millennials are using technology to create new ways of doing things, such as creating a digital video for a term project, playing video games instead of traditional board games, and connecting with friends and extended family worldwide through email, instant messaging, and social networking.5 they use technology to create new social and familial networks with friends that are based on the music they listen to, the books they read, the pictures they take, and the products they consume.6 they believe that their relationship with technology will change the way society views and relates to technology.7 with technology at their fingertips on a nearly constant basis, millennials have gained an expectation of instant gratification for all of their wants and needs.8 jenny emanuel (emanuelj@illinois.edu) is digital services & reference librarian, university of illinois, urbana. mailto:emanuelj@illinois.edu digital native academic librarians, technology skills, and their relationships with technology | emanuel 21 millennials believe that technology is not a passive experience, as it was for previous generations.9 to them, technology is active and an experience by which they live their lives.10 they have grown up with reality television, which means anyone can have his or her fifteen minutes of fame. in turn, this means being heard, having their say, and becoming famous online are all natural experiences that can be shared by anyone.11 because they can create their own customized media and make media consumption an interactive, as opposed to a passive and hierarchical, experience, they believe that everyone’s opinion counts and deserves to be heard.12 even though they believe they are the greatest generation and expert users of technology, others have a different view. for example, bauerlein argues that they are not intellectually curious, are anti-library, and blindly accept technology at face value while not understanding the societal implications or context of technology. they also consume technology without understanding how it works.13 within libraries, technology skills related to new librarians have been studied by del bosque and lampert, who surveyed librarians from a variety of library settings with less than nine years experience working as professional librarians. the survey found the majority (55 percent) understood that technology played a large part of their library education, but a similar percent (57 percent) did not expect to work in a technical position upon graduation. respondents also thought there was a disconnect between the technology skills taught in library school and what was needed on the job, with job responsibilities being much more technical than they expected. thus, even though more experienced librarians expected recent graduates to fill highly technical roles, library school did not prepare them for these roles and students did not opt to go to library school to gain strong technology skills. based on survey comments, the researchers noted two categories of new librarians: those who have a high level of technical experience, usually from a previous job in a technology related industry, and those who struggle with technology. for those who struggle with technology, technology was not the reason they decided to become librarians, and they wish their library school had more hands-on opportunities for technology instruction instead of teaching theoretical applications.14 method to understand, in part, the technology skills of millennial academic librarians and their attitudes toward technology, the author developed a two-part research study including an online survey and individual interviews with millennial librarians and library school students. first, an exhaustive three-part survey was created covering multiple aspects of millennial academic librarians, including demographics, career choice, specialization, generational attitudes, management, and technology skills. although the survey focused on many areas of data collection, this paper focuses only on technology skills. the survey was disseminated in may 2012 to 50 american library association (ala) accredited library schools in the united states as well as online outlets geared toward new librarians, including the new members round table (nmrt) electronic discussion list, nextgen-l (next generation librarians list), the ala emerging leaders program alumni electronic discussion list, and the ala think tank on facebook. the survey was information technology and libraries | september 2013 22 open for 10 days. the survey also asked participants if they would be willing to participate in a follow-up interview. a total of 161 participants volunteered for a follow-up interview. interviews began once the survey closed, and individuals were contacted via email to schedule an interview at their convenience. a total of 20 interviews were conducted in may and june 2012. the interviews were conducted using the audio-only function of skype and were recorded using the mp3 skype recorder software. the author then transcribed all of the interviews and coded the transcripts. the interview utilized open-ended questions to gather individual stories and offer support to the quantitative demographic and qualitative survey questions.15 the interview questions were semistructured and asked participants to explain in detail their path to becoming an academic librarian and their attitudes toward technology. results there were 315 valid survey responses. the birth years of participants ranged from 1982 to 1990 (see figure 1). the respondents were nearly evenly divided between library school students (45.5 percent) and individuals having already obtained a mls degree (52.1 percent). concerning the format of their library school program, 38.4 percent earned the degree at an institution entirely in person, 19.6 percent completed the degree entirely online, and 42.0 percent went to a program that was a mix of in person and online courses. figure 1.

very important. data on skills related to technology were gathered through several questions, notably by using a list of technologies commonly used in academic libraries and asking respondents to rate their comfort level before starting library school, after library school, and at the present time. the results are illustrated in table 1. technology before library school after library school at the

1. average comfort level with technologies before and after library school and at the current time. scale: 1 = very uncomfortable to 5 = very comfortable. this list can be split into categories based on the level of technical skill required. individuals were most comfortable with technologies that are used rather than technologies that enable people to create content, which generally require a higher level of skill. for example, people were comfortable with using content management systems (cms) and software used to create information technology and libraries | september 2013 24 webpages, such as dreamweaver, but they were not comfortable with the information architecture skills, css, and html needed to create more complex websites. there was also a lack of understanding about relational databases, which serve as the back end of many online library resources that all librarians use to accomplish most reference work. other deficiencies include linux, an operating system commonly used to run servers, as well as server set up and administration, which run all web-based library resources and services. there is also a strong lack of computer programming understanding and skills, including c++ and .net, as well as web programming languages such as php, asp, and perl. however, when asked which technologies they would like to learn, respondents listed computer and web programming languages the most often, along with other high-level technology skills, including xml, database software and vocabularies, geographic information systems (gis), adobe photoshop, and statistical software, such as spss. data from the technology questions also show that people are learning about technology in library school, but they are learning more about technology they already know how to use than technologies that are new to them. there are a couple of exceptions, including cms, course management systems, html, and screen casting software, with which respondents grew notably more comfortable while in library school (see table 1). more than 84 percent of respondents were required to take a technology course in library school, and they generally believed library school prepared them well to deal with the technological side of librarianship, rating 3.23 on a 1–5 scale. however, respondents did note that most of their technology skill was self-taught (81.7 percent), with only 47.5 percent stating that coursework contributed to their skills. an open-ended question asked what specific technology skills individuals wanted to learn. the results indicate that millennial librarians desire to learn more of the higher-level technology skills, especially programming, which was indicated in 28 of the 97 responses. other skills that were frequently noted include various elements of web programming, including scripting, xml, html, photoshop, microsoft access, spss, and gis. all of these skills either involve content creation (such as scripting, xml and html) or are complicated software that can require a great deal of training to master. see figure 2 for a tag cloud of technologies respondents want to learn. figure 2. coded tag cloud indicating responses to question, “are there any other technologies you want to learn?” digital native academic librarians, technology skills, and their relationships with technology | emanuel 25 clear trends emerged when millennial librarians were asked about technologies that will be most important to libraries in five year. mobile devices, including e-readers (such as the amazon kindle), apps, and tablet computers were the most common category of responses, followed by social media and social applications aimed at libraries. cmss for managing website content was also very popular, and website design was also common. advanced knowledge of database design, including relational database design, and the storage of library data frequently were mentioned, skills that were on a higher level than simply using databases to retrieve information online. web 2.0 applications were also commonly mentioned, but it is unknown if these overlapped with social media. e-books, not unexpectedly, were very popular. the most popular technology individuals wanted to learn was programming, which came up 25 times, indicating there may be a gap in the technical skills that librarians have and the skills they need to have. see figure 3 for a visualization of coded responses. figure 3. coded responses to question, “what three technologies will be most important to libraries in five years?” qualitative data interview participants exhibited a wide variety of diversity and roughly matched the demographics of survey participants. demographic information for survey participants was gathered from their survey responses. ten of the interviewees were born in 1984 or 1985, with the remaining ten born during the remaining years between 1982 and 1989. three participants were male, one did not indicate sex on the survey, and the remaining 16 participants were female. fifteen identified their race as white, two african american, one middle eastern, one hispanic, and one from multiple races. interview participants were from 14 different states. all participants were given pseudonyms for purposes of data analysis. the interview transcripts were coded into information technology and libraries | september 2013 26 broad categories, including attitudes about being digital natives, and technical skills relating to career choice. digital native issues related to being digital natives came up often when millennial librarians were asked to talk about their experiences using technology before they began library school, in library school, and on the job. however, not all considered themselves a digital native, very tech savvy, or able to pinpoint exactly what their tech skills are. most, however, did believe that there were differences in technology use and attitudes between librarians who were younger versus older librarians. childhood technology most remember when they first had a computer in their home as a child, so it was not a part of their lives from birth, but rather from a young age that most participants remember. betty and diana recall always having technology in their homes growing up because their parents worked in technology careers or had an interest in it as a hobby. as diana stated, “both [parents] worked in the it field, so when i was really little, they spent an astronomical amount of money on a computer back in the mid to late 1980s, so i’ve always grown up with technology.” others remember first being exposed to computers in school, with catharine saying, “i can remember being in elementary school and being on a computer and having specialized training. not just in typing but they even pulled people out of class to learn how computers work.” heather vividly remembers her family getting their first computer: “we got one in my house when i was like in the sixth grade and that was a huge thing.” participants also remember having internet access as a child. betsy noted, “i had a prodigy (online service) account when i was seven, when most people did not even know what the internet was at that point.” gabby said, “i think they call people between 21 and 30 the ‘in between’, because they knew what it was like before technology, but they also know how to use technology . . . because i remember before computers.” kelly talked extensively about how she grew up with technology: i think we got our first computer when i was in the fifth grade. i definitely grew up with it. i used it in school. i remember what life was like before computers, though. i have that little bit of perspective there. but it was definitely part of my daily life. and in college i joined facebook back when it was only for college students and now people cannot remember that now. but i used email, was one of the first users of gmail. i got a little more into it in college. olivia also talked about her use of technology as a child: we had a computer in my house. we were very fortunate because my dad was on top of that. so we had a computer since i was a little kid. so i would play around on that a lot, like aol and prodigy. i had the basic skills. and in high school we were taught basic word processing and excel. so i’ve always been in front of a computer. digital native academic librarians, technology skills, and their relationships with technology | emanuel 27 concept of the digital native most people believed they are digital natives because they have been working with technology for a long time, which sets them apart from older generations who they thought did not work extensively with technology until they were adults. catharine stated, “i know it has been a part of my life forever so probably my age does have something to do with it.” catharine talked about the differences in technology skill between herself and her older colleagues, but added, “i don’t feel there is an unwillingness for them to learn technology. i just don’t think they had experiences at the time, where maybe we’re just afforded more opportunities.” however, when pressed, not all considered themselves digital natives. abby recalls a class discussion about the idea of digital natives and how younger people may not be as good with technology as they perceive. because of this, she was hesitant to refer to herself as a digital native, even though growing up she believed technology was a part of her life. others, such as betsy, are reluctant to call themselves digital natives because they remember when their family first got a computer and it was not always in their household. there were also a couple of outliers who were reluctant to call themselves digital natives because they did not grow up with technology in the same ways as did many of their peers. rachel grew up in a poorer home that always got technology second-hand, and she always thought they were behind others. although her family first had an apple computer in the 1980s, she did not recall using it, and just thought of it as a sort of “new appliance” in her house. her family did not emphasize technology use and saw it as something not worth investing in until they had to, which gave her a different perspective of using technology only as necessary and as “one of those things that sometimes i just don’t want to deal with.” samantha grew up in a rural area that only had dial-up internet, which embarrassed her and did not work as well as she thought it should, so she did not use it, leading to a belief that she did not grow up on the internet in the same way as her peers. because of this, she did not consider herself a digital native: i’m still able to relate to those in a different generation who have no idea where to start [with technology], because i was at that state recently. . . . i’m at the in-between stage, so i can handle both ends of the [technology use] spectrum. but yeah, i’m not a digital native. technology reaction participants assumed that, because of their age, they were not as scared or intimidated by technology as they thought some of their colleagues were. heather talked about how learning new things would initially make her nervous, but then would get excited about what the new program or application could do for herself or her work. francis stated, “i’m not afraid of the technology.” she also talked about the differences between herself and her older colleagues: if you ask them something different or to learn something new, they will make it more complicated. i’m so used to exploring my options, i don’t think about it. those 20–30 years older than me are comfortable knowing what they know how to do but not necessarily exploring new ways of doing something that they already know how to do. they feel pretty comfortable and confident in their skills information technology and libraries | september 2013 28 but aren’t really looking to test the waters to see if there is a different way to do something. . . . i’m willing to try. i see a lot of people that are afraid they are going to break something and don’t want to click on it. and i have the confidence that if i click on something, then i can pretty much undo whatever that does. so not necessarily skills, but a different mindset or something. as francis inferred above, younger librarians, because they have always used technology, believe they can quickly learn new technologies. quinn, a current student, also talked extensively about this: i definitely think my age has a lot to do with how comfortable i am with it. because there are various ages within [my library school] and i have definitely noticed that older people fear it a bit more. i guess i can attribute my age to being embedded in technology. because i’ve always had it, well i haven’t always had it, but i had it young enough to feel like it is a part of me, as opposed to new fangled and wasn’t with it in the beginning. . . . i’m not afraid of it, i’m not afraid to mess around with it and mess things up. because you can always reboot or start over. i think that’s the biggest thing, like i will work on something and mess around with it until i figure it out as opposed to someone who is older who wants to know something exactly the right way so they don’t want to do anything bad to it. heather stated: i think i’m a bit more open to new technologies than some of my older colleagues. . . . i have the feeling i know a little bit more. . . . i’m not sure it is just because my comfort level was higher or maybe their experiences make them more cautious about new things, but i think the younger librarians are more quick to latch on to new things. other participants shared this same belief when talking about the difference in work styles and technology use among different ages in their workplace. technology skills the individual technology skills individuals described focus on the use of technology, not the creation of it. francis described this: i don’t have any programming or coding [experience] or building physical computers or anything like that, but just general using a variety of devices like the ipad, iphone, everything is all integrated. i like being able to use technology in my personal life. no one responded that they knew how to program and work with servers, though edward said he had “fiddled with linux as a server” but did not spend a lot of time with it. olivia and quinn, however, did express interest in learning how to program, understand the back end, and create emerging technologies. betty mentioned using sql and xml in her workplace and aired her frustrations that people just expect to be able to use technology without learning how it actually works and what went into making that device or service. several people mentioned working in web design, but only a couple people mentioned creating webpages with html and css, though several had experience using tools such as dreamweaver or frontpage. ian mentioned that it was part of her public library job to assist patrons with using their personal devices, while others digital native academic librarians, technology skills, and their relationships with technology | emanuel 29 stated that when they have technology problems, they simply contact their it departments. many participants mentioned using social media and various web 2.0 applications such as facebook and twitter, both personally and professionally. when asked to compare their tech skills from before they became librarians to after, some described minor changes in skills, such as learning html, but others mostly indicated that library school helped them learn new applications, existing technologies, or new technology resources, most without going into detail. quinn talked about her tech skills in relation to what she is learning in library school: i think they [technology skills] are actually above average. i’ve taken a few of the courses that are offered in terms of tech, and they are totally below what i already know. but other classmates have thought it was really hard. but i’ve had prior knowledge of it. patricia stated she started using online tools more extensively after learning about them in library school. one talked extensively about using webinar software and libguides to deliver instruction online, while another stated library school inspired her to start a blog that she did not keep up, and another became an extensive twitter user. jan focused on digital librarianship while in library school because she saw it as the future of libraries. she thought that library school helped her do some “encoding on some projects and how to do webpages,” but it barely touched on the skills needed to actually perform a job within digital librarianship. she would like to get more into the development side of library technology, but in her current job there is not the time or support to further advance those skills. a couple of participants talked about learning about usability and the evaluation of technologies. a few interview participants mentioned the tech skills of people even younger than they are, or current college students they work with. betty did not see younger coworkers understanding what is needed to develop or understand the back end of technology and believed younger workers do not use technology to communicate as effectively as they could. edward, who works at a for-profit career college that has many poorer and nontraditional students, stated, it is “not just the 50 year olds, but the 18 year olds who don’t know how to attach documents to an email.” when pressed as to why she thinks young students struggle with basic technology tasks, he stated, “at times i think that has a lot more to do with their k–12 experience and if they had access to computers and stuff. i don’t know. it just blows me away sometimes.” gabby, currently working in appalachia, said, “not everyone here has computer skills, not everyone has access to it at home or maybe can’t make it to the library. . . . i think it is awesome to have those things at your fingertips, but not everyone does.” on the other hand, diana believed that she does not “have the same relationship with technology like i’m seeing some of the college students now where they are hooked in all the time and they are just going for it”. she also said that she “wouldn’t call myself a digital immigrant, but i’m very comfortable using technology but not to the extent i’m seeing many people i see now.” information technology and libraries | september 2013 30 tech skills related to career choice the researcher sought to determine the role of technology in determining the career choice of librarianship. those interview participants who talked about using technology did not mention it as a reason they became a librarian. survey responses indicated that opportunities to use technology were an important reason to become a librarian, but participants did not stress technology during the interviews. participants were much more likely to specify their love of the academic atmosphere or their general interest in research first and then maybe think of technology as an afterthought. gabby mentioned, after a long list of things that influenced her career choice, “and technology and stuff.” only taylor talked extensively about how technology influenced her choice. a current library school student, she wanted to go into archives and is really excited about how much information is being digitized and put online: you know how everything on microfiche is now digital? everything seems to be digitized as well, you know books and e-books and journals. being able to take something and scan it and put it online for users to access. it is definitely an important thing. so yeah, that definitely influenced me on becoming a librarian. jan decided to specialize in digital librarianship while in library school because she saw it was the future of library work. rachel, who has observed similar attitudes among her classmates, shared this thinking as well. however, heather admitted she did not have a lot of technology experience before going to library school and did not believe that her master’s program prepared her to go into the technology oriented digital librarianship. several participants talked about how their background using search engines such as google and doing research online would make them better librarians, but none talked about these as factors related to choosing librarianship as a career. abby talked about how she always uses google to look things up, and that it is nice to have found a career that rewards such use. diana discussed how she had always been good at finding information online since she was a child, which helped her narrow her career choice to academic librarianship, as she believed it was the best match for these skills. instead of talking about how technology influenced their career choice, participants were more likely to talk about the fact that technology did not influence them. abby stated, “i don’t think [technology influenced me] because i didn’t really know that librarians needed a lot of technology skill.” edward stated he, “didn’t do any technology in library school because i didn’t want to go in that direction,” reiterated this. rachel, who strongly did not consider herself a digital native, stated she was drawn to librarianship, specifically access services, because she liked working with print books rather than using online resources to find information. she commented, i really liked looking for books and i used the card catalog when i was a kid, but i can use a computer to help people find things, but it was like, i really just liked finding the books rather than electronic digital native academic librarians, technology skills, and their relationships with technology | emanuel 31 information. i guess i feel like it feels comfortable and safe, like books. and you can hold them and you can touch them. and sometimes i feel like they should always be a part of the library. i took a digital libraries course this past semester and i felt like i was the only one being like, “no, we still need physical books,” so i was actually realizing how intimidated i am with technology. i’m totally willing to adapt, and i’m willing to work on these issues, but i do feel like i want the library to still be a place that has the traditional feel. samantha also did not feel like a digital native, as she grew up in a rural area that only had access to dial-up internet. she went on to describe how she did not work with online tools until college and she was relieved when she did not have to use such tools during a year off between college and graduate school. although she recognized technology use by librarians is helping libraries not becoming obsolete, she only learned what she needed to learn in order to complete library school, so it did not influence her career choice. implications millennials are very comfortable with technology, though there are limitations to their skills. for the most part, they have a lifetime attachment to technology,16 but they do remember a time without having a computer in their homes or when computers were something only used at school and for basic instruction. as interview participant frances put it, “nothing like how students get to use them now.” millennial grew up with computers, but early on, they were not advanced enough to do the multimedia creation and application building that is done now, and they mostly use resources that were developed by others. however, millennial librarians in this study do see the utility that computers have in everyday life, and by high school, many stated that computer use was required for them to go about their academic and personal lives, but they thought that technology in its current state with online research resources and social networking did not come about until they were in college. additionally, most interview respondents said that library school helped acculturate them into using technology more frequently. however, not everyone in the study grew up with a computer or internet access in his or her home. two interview respondents refused to call themselves digital natives. one said she grew up in an environment without much money, and the only technology her family had access to was often secondhand and several years behind. the other participant grew up in a rural area that did not have access to high-speed internet, and as a result, she was rarely online until college. both individuals believed that technology was definitely not a factor in them being drawn to librarianship, and they were more interested in the circulation and the print resources than in specializations that require a high level of technical knowledge. other participants were quick to acknowledge that there are many members of their generation who, for one reason or another, do not have an interest in technology and may not have had the resources growing up to have incorporated it into their daily lives. some participants noted there was some computer instruction starting in elementary school, but it was very basic computer literacy, and most of their technology learning occurred at home when there was the time to focus on tasks that were more complicated. information technology and libraries | september 2013 32 even though study participants remember a time without technology in their homes and they believe that technology did not mature to its current state until they were in college, they have used it for a much larger percentage of their lives than older generations. for that reason, they are quick to learn new technologies as they become available or are required based on professional needs. they also believe that because computers had matured alongside them, they are not afraid to break them. interview participant abby states, “i have a lot of faith in technology.” millennials believe that they can experiment with technology without fear that it will become inoperable or cause additional headaches in the future. they are also not wedded to particular technologies and do not get frustrated by current technologies and applications because they think something newer and better is always around the corner. one disconnect in the technology skills of millennials is that most of them are accustomed to using technology, not creating it or understanding the back end infrastructure. as one interview participant said, “they expect everything to be easy, but they don’t understand what went into trying to make it easy.” although many librarians indicated they use tools such as camtasia to create multimedia projects, many thought they had weak skills in this area and desired to learn more. they are also most likely to edit content on webpages using a cms system such as drupal or libguides instead of creating more elaborate websites utilizing information architecture principles or more complex web programming languages (such as php) or relational databases (such as mysql). they rely on dedicated tech people to set these up and maintain the servers that house these services, but they desire to learn more about these technologies themselves. there is also a strong desire to learn more traditional computer programming languages such as c++, c#, and perl. many participants thought library school only affected their technology skills marginally, and they desire to learn higher-order skills that can be applied to their job. millennials are comfortable learning front-end technologies on their own, but they need help understanding the technology behind the tools they use in their daily lives. conclusion this mixed-methods study examined many characteristics of millennial librarians, and this article noted their technology skills and attitudes toward technology. the findings indicate that technology did not play a major role in their decision to become academic librarians. the data also reveal that, although millennial librarians mostly grew up with technology and believe this sets their skills apart from older librarians, their skills are mostly in using technology tools and not in creating them. they also believe their status as digital native has allowed them to recognize that librarianship is changing as a career. however, millennial librarians still respect their older colleagues and the skills associated with traditional librarianship and are firmly rooted in traditions. millennial librarians just want to be able to shape the profession in their own way. digital native academic librarians, technology skills, and their relationships with technology | emanuel 33 references 1. william strauss and neil howe,

student, indiana university. © 2021. abstract controlled vocabularies used in cultural heritage organizations (galleries, libraries, archives, and museums) are a helpful way to standardize terminology but can also result in misrepresentation or exclusion of systemically marginalized groups. library of congress subject headings (lcsh) is one example of a widely used yet problematic controlled vocabulary for subject headings. in some cases, systemically marginalized groups are creating controlled vocabularies that better reflect their terminology. when a widely used vocabulary like lcsh and a controlled vocabulary from a marginalized community are both available as linked data, it is possible to incorporate the terminology from the marginalized community as an overlay or replacement for outdated or absent terms from more widely used vocabularies. this paper provides a use case for examining how the homosaurus, an lgbtq+ linked data controlled vocabulary, can provide an augmented and updated search experience to mitigate bias within a system that only uses lcsh for subject headings. introduction controlled vocabularies are a vital part of how individuals and communities are understood and discussed in scholarly discourse and research. controlled vocabularies are also a way to standardize terminology and allow items to be grouped by common subjects for easier discovery and access points. while larger, more universally recognized vocabularies like the library of congress subject headings (lcsh) exist, they are often slow to be updated and they reflect a largely white, heterosexual, cisgender, male, christian-centric point of view.1 when the terminology used to define a systemically marginalized group is determined by those outside of the group, often the terms are outdated or reflect a biased perspective.2 the prevalence and continued use of outdated metadata and vocabularies in discovery systems creates a cycle of biased search practices that can be difficult to break without the help of information professionals and outside resources. controlled vocabularies that have been created by or have the input of marginalized communities tend to be more inclusive and up to date. unfortunately, these vocabularies often are not known to the public or to researchers not well versed in metadata practices. providing access to controlled vocabularies created by marginalized communities and linking them to existing vocabularies such as lcsh can help make the search process more representative of the people who are using discovery systems and can connect them to resources that better represent themselves and their needs in a complex information world. lcsh terms are available as linked data, a format that enables online machine-readable connections between concepts and terms, and there needs to be an effort to make systems using lcsh terms more inclusive and representative of marginalized communities. the project described in this article built and gathered feedback on a proof-of-concept javascript application to show how defined connections between vocabularies can be used to provide alternative and mailto:jlhardes@iu.edu mailto:anolan147@gmail.com information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 2 often enhanced access to library catalog resources. in this instance, simple knowledge organization system (skos) relationships link lcsh subject terms to the homosaurus linked data vocabulary, an “international linked data vocabulary of lgbtq terms that supports improved access to lgbtq resources within cultural institutions.”3 skos is “a common data model [from the w3c] for sharing and linking knowledge organization systems via the web.”4 this project uses skos:exactmatch relationships defined by the homosaurus to enable researchers to use homosaurus terms to search a library catalog and retrieve relevant results based on the connected lcsh terms that are already in the catalog record.5 subject searches are conducted when the homosaurus term and the lcsh term match exactly, since the lcsh term’s presence in the library catalog record indicates a specific grouping of records could have this subject term applied. if the homosaurus term does not match exactly to the lcsh term, a keyword search is conducted using the homosaurus term to retrieve library catalog results where the homosaurus term appears in any indexed field in the catalog record, including creator-supplied title and abstract information. using a vocabulary like the homosaurus this way helps to connect researchers to resources that more accurately reflect systemically marginalized communities and potentially more accurately reflects the researchers themselves. by providing connections for users that they would otherwise have difficulty finding without the help of a librarian or other information professional, projects such as this one hope to combat the cycle of biased metadata and biased research practices that has dominated academic research. literature review students in higher education who identify as members of systemically marginalized communities can continue to experience marginalization within higher educational institutions, and the academic library setting is no exception. brook, ellenwood, and lazzaro provide analysis of multiple studies showing the effect of mostly white staffing in academic libraries, the impact this can have on reference services provided to patrons from marginalized communities, and the overwhelming and intimidating spaces in sizable academic libraries that can be “compounded for students who already feel that they do not belong on campus on the basis of their race.” 6 when considering how this experience impacts using an online library catalog or digital repository system for conducting research, these same students can find themselves not well represented.7 additionally, crossing disciplines to capture intersectionalities of an identity can be complicated by narrow controlled vocabulary terms which compound problems that already make interdisciplinary research difficult.8 drabinski proposes that the library catalog should be treated as a biased text that requires critical thinking to understand.9 subject headings from authorities such as the library of congress will never be unbiased as attitudes, perspectives, and identities change over time. it is therefore important to leverage information literacy competency standards put forward by the association of college & research libraries and teach students how to critically engage the library catalog as another information source. library instruction is one way to ease the challenges faced by marginalized researchers in higher education, helping researchers effectively use a system like a library catalog that incorporates biased subject headings. however, with interdisciplinary research, materials are often dispersed across information systems and physical locations, and there is still the challenge to identify and locate everything relevant to the research topic.10 using available fields within the library catalog record itself (the 590 in marc, for example) can identify cross-disciplinary resources. examples are provided by hogan for black lgbtq resources and latina lesbian literature.11 what all of these efforts seem to point to is what hannah buckland proposes: changing the framing of catalog records from “aboutness” to information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 3 “fromness,” providing “culturally-responsive metadata” that j. l. colbert recognizes can create an “equitable subject access” experience that “center[s] the information needs and information seeking behaviors of those whom our systems disenfranchise.”12 these changes can often only be implemented locally due to language variation and localized community relevance; but colbert then considers how linked open data might prove useful to combine or relate different subject or community vocabularies. “when we decenter the idea that for every concept there is one controlled term to describe it, we allow the play of seemingly opposite ways of thinking. . . . a linked open data catalog allows libraries to complement, replace, or even reject the standards that have been decided for us and our patrons.”13 librarians and archivists have suggested and tried other methods to mitigate the impact of systemic marginalization. these efforts go beyond the use of controlled vocabularies in the creation of catalog records. one of the earliest and most significant examples of this is dorothy porter’s work in organizing the collections she managed at howard university. up to that point in the 1930s and 1940s, dewey decimal classification (ddc) was used to organize works on the shelf. many libraries of the time were predominantly white institutions and dorothy porter remembered them using ddc to shelve anything by a black author or about the black experience under the ddc heading for colonization (325) or slavery (326).14 porter instead organized her collections based on subject matter, genre, and author, categorizing the work based on what it was about rather than the race of the author or the race of any people mentioned in the work. this subtle yet fundamental shift shows the real impact that libraries have on access to collections for their audiences. hope a. olson and dennis ward created a proof-of-concept microsoft access database interface connecting mary ellen capek’s a women’s thesaurus to the dewey decimal classification scheme to offer an end user interface for searching a ddc system using the thesaurus terminology. the idea, initially from joan mitchell (then editor of ddc), was to develop “a means of making ddc accessible from the point of view of a marginalized knowledge domain—in particular, creating a means of browsing ddc from a feminist/women’s studies perspective.”15 variables were defined from characteristics of different classifications to enable a systematic match to thesaurus terms. dorothy berry’s work at university of minnesota libraries to gather and digitize african american-related materials from across archival collections for aggregating in umbra search african american history shows an option for pulling a collection from other collections and highlighting what would otherwise remain marginalized items from marginalized communities.16 discovering these materials required searching with a variety of terms used over time to refer to african americans. adding collection level context at the folder level for these materials allows aggregation without losing original place and context, while at the same time centering the marginalized communities represented in these materials by gathering them from these various and marginalized original locations. archives for black lives in philadelphia is “a loose association of archivists, librarians, and allied professionals in the philadelphia and delaware valley area responding to the issues raised by the black lives matter movement.” within this group, the anti-racist description working group has compiled an annotated bibliography and metadata recommendations to address racist and antiblack archival description.17 the recommendations focus on the black community but can be applied more broadly when describing records by and about any marginalized community. the information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 4 recommendations include decentering “neutrality” and “objectivity” for “respect” and “care,” particularly when deciding on controlled vocabulary terms to use in archival description. specific recommendations to use “terminology that black people use to describe themselves,” to recognize that this “terminology changes over time, so description will be an iterative process,” and to consult “alternative cataloging schemes created by the subjects of the records being described when and if they are available” provide an approach that looks for descriptive terms from within the community and moves away from terms applied to a community by others.18 paying attention to the controlled vocabularies applied to archival description helps to change the narrative and the power structure of the historical record, centering those who have been marginalized and oppressed and increasing discoverability and access to their stories and perspectives. allowing for changes in controlled vocabulary terms keeps systems flexible enough to accommodate changes in a community’s terminology over time. linked data relationships can connect term changes for more comprehensive searching while also identifying the current controlled vocabulary term to use. the lavender library, archives, and cultural exchange (llace) community archives in sacramento, california is an archive for a marginalized community.19 in developing archival and circulating library collections that serve the queer community, the library collections use a thesaurus of queer terms from dee michel for classification and the archival collections use subject headings from michel’s thesaurus along with lcsh.20 the focus, again, begins with the community being served and recognizes that widely used controlled vocabularies like lcsh do not serve these collections or communities well. starting with a community-specific vocabulary and then connecting lcsh terms centers the collections and community first and then makes connections to the larger library and archives community possible. other efforts have used alternatives or supplements to common vocabularies and schemes. the xwi7xwa library’s use of the brian deer classification system at the university of british columbia incorporates names and terminology from the first nations community to better represent that community beyond what something like library of congress classification provides. using accurate names of nations and peoples, according to the head librarian, ann doyle, helps create identity among users of the collection and “shapes the research and types of questions that people ask.”21 the national indian law library began cataloging using local terminology only. as it moved records online and sought to be more discoverable and cooperative with other libraries, this local terminology was synchronized with lcsh and specialized terms for federal indian law and tribal law were kept as a supplement.22 doing this work is not only about changing terms on catalog records but also learning and making connections with communities who have been marginalized by these systems. farnel et al. explain the process of decolonizing both the library catalog and digital collections description at university of alberta libraries through investigation, analysis, partnering with other institutions doing this work and, most importantly, reaching out to indigenous communities represented in these records to engage and learn about the most appropriate terminology to use.23 different methods and attempts to center the marginalized in cataloging and collection description show it is possible and essential to voice the concerns of those least represented in order to have the most impact on all researchers using these resources. widely used controlled vocabularies like lcsh continue to be a major way to aggregate collections and provide common access points. groups like the association for library collections and technical services’ information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 5 cataloging and metadata management section subject analysis committee continue to work to change terms in these vocabularies to provide better and more accurate representation for systemically marginalized communities, but the process is slow and will likely never be enough.24 incorporating vocabularies from systemically marginalized communities for use either on the cataloging/description side or for researchers to use for search and discovery offers possibilities for more inclusive experiences that center marginalized voices and expand the options for research questions to ask and answer. methodology to test this idea that connections provided between a systemically marginalized community’s controlled vocabulary and a more generalized vocabulary like lcsh could be helpful, a proof-ofconcept information retrieval aid was conceived. the idea was to create a lightweight javascript application that could use a select set of terms from the homosaurus (http://homosaurus.org), an lgbtq+ vocabulary originally created by ihlia lgbt heritage (https://www.ihlia.nl/?lang=en) and now also used in its linked data form by the digital transgender archive (https://www.digitaltransgenderarchive.net), to connect to lcsh terms and provide search links against a library catalog (iucat, https://iucat.iu.edu, indiana university’s online library catalog) that uses lcsh for subject headings. homosaurus version 1 was used initially and did not identify connections to lcsh terms. analysis of homosaurus terms against lcsh terms suggested some connections could be made and for initial construction of the proof-of-concept application these were used, but with the recognition that these connections were not coming from the community vocabulary. this was a problem since the point in mitigating bias is to use the community’s definitions and any outside interpretations are necessarily not going to reflect the community’s intentions. as the application concept continued to form and the initial term comparison work continued, homosaurus version 2 was released containing explicit connections to lcsh terms, using skos:exactmatch for mapping those connections. those connections in version 2 are not expressed as linked data but are provided in the vocabulary’s site for each term. the proof-of-concept work switched to using select terms from homosaurus version 2 in order to make use of the lcsh connections now being provided by the community.25 the proof-of-concept application used the select set of homosaurus version 2 terms downloaded as json-ld and added in the lcsh terms using the supplied skos:exactmatch relationship. the user interface provided visual connections from the selected homosaurus term to its narrower, broader, and related terms within homosaurus. any exact matches to lcsh terms and any use for terms homosaurus indicated should be replaced by this term were provided together. the visual layout for the application is directly influenced by the ihlia lgbt heritage collections browse interface.26 in ihlia’s system, after searching for a term (“love,” for example), the interface provides broader, narrower, related, and used for terms as suggestions for other ways to discover items in these collections in a visually connected bubble layout surrounding the search term. those connections are linked and can be used to navigate ihlia’s controlled vocabulary, which also happens to be powered by a local non-linked data form of the homosaurus vocabulary. in the proof-of-concept application, for terms where there is an lcsh exact match, the lcsh term was used for the connection to search iucat and was only revealed on screen if the exact match (lcsh) bubble was clicked by the user (see fig. 1). http://homosaurus.org/ https://www.ihlia.nl/?lang=en

aid showing the homosaurus term “transgenderism” linked to search iucat. exact match (lcsh) shows the lcsh term “gender nonconformity” (also linked to search in iucat) along with narrower, broader, and related homosaurus terms. the initial proof-of-concept information retrieval aid javascript application was shared with and tested by olivia adams, a graduate student at indiana university working as the library coordinator for the lgbtq+ culture center library at indiana university (https://lgbtq.indiana.edu/programs-services/library/index.html). this library has adapted the llace classification system, the shelving organizational scheme developed by the lavender library in sacramento, california (http://lavenderlibrary.com), for organizing its own physical collection of resources. the lgbtq+ culture center library also has its own online library catalog that makes use of an established local list of tags for items included in that system (https://www.librarycat.org/lib/iuglbtlibrary/). the information retrieval aid application was first presented to the lgbtq+ culture center library coordinator for general impressions and feedback. additionally, specific tasks were proposed. please note that the proposed tasks use a vocabulary term as an example that is offensive and outdated. the results of this testing, along with feedback from the homosaurus editorial board, clarified the need to change the information retrieval aid to supply this additional contextual information (available in homosaurus as a description for the term). the tasks presented for trying the information retrieval aid were the following: https://lgbtq.indiana.edu/programs-services/library/index.html http://lavenderlibrary.com/ https://www.librarycat.org/lib/iuglbtlibrary/ information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 7 • you want to find resources at iu about transgenderism. what do you think of the resources that iucat is offering through this information retrieval aid? • how do the homosaurus terms you are seeing here compare to the llace classification terms or the tags/subjects you use in the lgbtq+ library catalog? • what is the importance of transparency for the lcsh terms in relation to community values (for terms that are different and only shown in the hidden section right now)? “transgenderism” is a term homosaurus connects to lcsh’s term “gender nonconformity” with an exact match relationship (http://homosaurus.org/v2/transgenderism). to provide results for answering the first question, the proof-of-concept information retrieval aid interface showed the homosaurus term with a linked search in iucat that provided results using the lcsh term as a subject search.27 the second question was asked to get a sense of the relevance of the homosaurus terms to the collections organized and housed in the lgbtq+ culture center library. the third question about the importance of transparency for the lcsh terms in relation to community values was meant to investigate how a system like this proof-of-concept information retrieval aid might be used by the community of researchers and patrons using the culture center’s library, and if the mechanism to mask the lcsh term in favor of the homosaurus term is useful or not. the code for this javascript web application in its current state is available on github at https://github.com/jlhardes/metadatabias. the initial proof-of-concept application was developed by justina kaiser, at the time an information and library science graduate student at indiana university. the current code is a fork of her project, also available on github (https://github.com/juskaise/metadatabias). discussion sharing this proof-of-concept information retrieval aid using homosaurus terms with the lgbtq+ culture center librarian revealed the importance of usability testing and being receptive to a community’s needs. an introduction and explanation of the controlled vocabulary and the community it represents was a recommended addition since the term list presented was not initially easily identified. additionally, the interface terminology of narrower/related/broader/exact match/use for is familiar in the library world but not necessarily for the casual user. this terminology is still in use by the information retrieval aid but is under review for updated labels that are easier to understand. this initial version kept any use for terms hidden unless the user clicked on that bubble in the interface to see them. the reasoning was to give more emphasis to the homosaurus term and to keep any potentially derogatory or harmful terms still in use by lcsh out of the way of researchers (even though the searches conducted against the catalog might need to use those terms if no other linked data connection is available). feedback here was helpful: hiding terms that homosaurus does not recommend might hinder discovering results if the researcher wants to search on a term that is no longer used by the community or is considered derogatory or harmful. this is a useful lesson in that covering up the past is not helpful to those in a marginalized community who have experience with that marginalization or those trying to learn about the past experiences of a marginalized community. also, being able to find all relevant resources can mean a variety of terms (both current in the community and no longer current) might be necessary. the homosaurus editorial board also explained that use for terms are sometimes slang terms and are not always considered derogatory. this information is helpful in figuring out how to present lcsh terms in the interface http://homosaurus.org/v2/transgenderism https://github.com/jlhardes/metadatabias https://github.com/juskaise/metadatabias information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 8 in the context of the homosaurus terms. additionally, moving use for terms next to related terms connected these sets of terms better than placing use for terms with exact match terms. further feedback from the homosaurus editorial board regarding the example term used for testing showed the terms and their connections to other terms do not supply enough information to express the full meaning of the term within the community. without supplying the homosaurus description for the term “transgenderism” (“pathologizing term often used in the medicalization of transgender people; use only in historical context,” see http://homosaurus.org/v2/transgenderism), the term can come across in the information retrieval aid as a preferred term from the community when, in fact, it is not. this was a critical update needed for the information retrieval aid to be effective as a research tool. in using the proof-of-concept interface to search against iucat, it was noted by the lgbtq+ culture center librarian that using the lcsh term to conduct a subject search against the catalog might not produce useful results if the homosaurus term is not an actual exact match to the lcsh term. in this case the homosaurus term should be searched in the catalog as a keyword instead of a subject, so the search is conducted on all indexed fields in the catalog record. in the example tried for the term “transgenderism” the skos:exactmatch relationship is defined as the lcsh term “gender nonconformity” (see fig. 1). even though the relationship is identified in homosaurus as an exact match, searching for “gender nonconformity” as a subject term in the catalog (267 results) and “transgenderism” as a keyword in the catalog (289 results) arrives at different result sets with different types of entries (see figs. 2 and 3). use for terms, while not always representative of the community providing the vocabulary, do have possible historical relevance if present in supplied information (such as a title) and can be connected to the catalog via keyword searching as well. there is an importance to revealing these differences within the library catalog and providing results that reflect the terms used by the community. the library’s applied terminology via subjects organizes a different set of resources compared to searching for terminology available via titles or other information supplied by authors and creators. when considering who is part of a community and who is not in this scenario, there are benefits to trying to work around or in addition to the library’s applied organizational scheme. subject searching in the catalog provides another view (and set of results) for those familiar with the community’s terminology. those approaching a research topic from outside of a community are able to learn more about how to find resources most effectively, moving from the catalog’s terminology to the community’s terminology. after trying the proof-of-concept information retrieval aid, the lgbtq+ culture center librarian provided feedback that this could be useful for people new to studying the lgbtq+ community and unfamiliar with the community’s terminology. with an introduction and explanation of the controlled vocabulary in place and an easy-to-follow interface to guide users through the vocabulary terms, effective searches against the catalog that also reveal terminology used by the community and differences between that terminology and the catalog’s terminology can be both educational and useful for research. http://homosaurus.org/v2/transgenderism information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 9 figure 2. searching indiana university’s online library catalog (iucat) for the lcsh term “gender nonconformity” as subject shows 267 results. information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 10 figure 3. searching indiana university’s online library catalog for the homosaurus term “transgenderism” as keyword shows 289 results. one of the largest obstacles to connecting marginalized communities to reliable, representative controlled vocabularies is the lack of controlled vocabularies that are readily available as linked data. unless an individual or organization has made the effort to establish connections between a community’s vocabulary and lcsh, the representative vocabularies stand alone and remain difficult to discover or use. the proof-of-concept testing of this project illustrates not only the need for connections to community-created controlled vocabularies, but also that having access to those vocabularies can result in more accurate and effective searches and usage of catalog resources. although vocabularies like lcsh contain outdated terms, having access to a variety of terms that are acceptable at different points in a community’s history can be useful for researchers who may not be as informed about certain systemically marginalized communities and whether certain terms have been completely eliminated, reclaimed, or replaced by more accurate terminology. efforts to mitigate bias in metadata via linked data are representative of a larger effort to correct a long-standing issue in libraries and other fields where the voices and perspectives of marginalized individuals have been overshadowed by the voices and needs of the majority. in addition to working to update large, generalized vocabularies and trying to incorporate these voices and information technology and libraries september 2021 mitigating bias in metadata | hardesty and nolan 11 perspectives, this change in method is meant to add those voices and center their importance. by linking community-created vocabularies and placing them front and center in the search process, metadata can become a tool with which to center the voices of marginalized communities and move toward a more equitable method of searching, finding, and using resources. conclusion the information retrieval aid is still progressing beyond a proof-of-concept but it has seen significant updates since its initial implementation. figure 1 shows the initial proof -of-concept that was tested. introductory information has been added to explain the homosaurus vocabulary and the information retrieval aid tool itself. more terms are available (although still not the full set of homosaurus version 2 terms) and the term list in json-ld is being used to automatically populate the term list in the interface. if available, the term description is provided for more complete context. additionally, no terms are hidden in the bubble navigation and use for is located with related terms now. future work for this project includes incorporating the full list of homosaurus terms; reconsidering the category names (narrower/related/broader/exact match/use for) to determine if there are better labels to use for these categories that will be easier to understand for a general research audience; and testing the tool with researchers new to lgbtq+ terminology as well as those more knowledgeable about the lgbtq+ community and its terminology and history. additional areas of work that welcome investigation include automating the term list generated for use with the information retrieval aid (via api calls, for example) to help reflect any changes or updates made to the community vocabulary over time; the technical implications of connecting this information retrieval aid to a search engine beyond indiana university’s online library catalog; and using this tool with controlled vocabularies from other systemically marginalized communities, such as the bc first nations subject headings, the glossary of disability terms from the north carolina council on developmental disabilities, or atria: women’s thesaurus from the institute on gender equality and women’s history.28 what difference does it make to use a different search engine that incorporates lcsh terms? likewise, is it possible to connect other linked data (or non-linked data) controlled vocabularies from systemically marginalized communities and is that effective for retrieving information and improving research outcomes? the work so far shows the possibility of centering systemically marginalized voices by using the system more effectively, making linked data work to connect and update the terminology and search terms available for research.

revealing to the authors as a better term to use than “historically marginalized communities.” this is significant in that it emphasizes the continued oppression and marginalization of these

improve user satisfaction with the effects of retrieval results and visual appearance by employing users’ own information. user feedback on digital platforms has been proven to be one type of user cognition. through conducting a digital literature resource organization model based on user cognition, our proposal improves both the content and presentation of retrieval systems. this paper takes powell's city of books as an example to describe the construction process of a knowledge network. the model consists of two parts. in the unstructured data part, synopses and reviews were recorded as representatives of user cognition. to build the resource category, linguistic and semantic analyses were used to analyze the concepts and the relationships among them. in the structural data part, the metadata of every book was linked with each other by informetrics relationships. the semantic resource was constructed to assist with building the knowledge network. we conducted a mock-up to compare the new category and knowledge-recommendation system with the current retrieval system. thirty-nine subjects examined our mock-up and highly valued the differences we made for the improvements in retrieval and appearance. knowledge recommendation based on user cognition was tested to be positive based on user feedback. there could be more research objects for digital resource knowledge recommendations based on user cognition. introduction the concept of user cognition originates in cognitive psychology. this concept principally explores the human cognition process through information-processing methods.1 the concept characterizes a process in which a user obtains unknown information and knowledge through acquired information. as information-science workers, we may explore the psychological activities of users by analyzing their cognitive processes when they are using information services.2 a knowledge-recommendation service based on user cognition has become essential since it emphasizes facilitating collaborations between humans and computers and promotes the participation of users, which ultimately improves user satisfaction. a knowledge-recommendation system is based on a combination of information organization, a retrieval system, and knowledge visualization.3 however, when exploring digital online literature resources, it is difficult to quickly and precisely find what we want because of the problem of information organization and retrieval. most search results only display a one-by-one list view. mailto:2012101040015@whu.edu.cn mailto:1830233606@qq.com mailto:jiangen.he@drexel.edu of the people, for the people | lou, wang, and he 67 https://doi.org/10.6017/ital.v37i3.10060 thus, adding visualization techniques to an interface could improve user satisfaction. furthermore, the retrieval system and visualizations rely on information organization. only if information is well designed can the retrieval system and visualization be useful. therefore, we attempt to improve retrieval efficiency by proposing a digital literature resource organization model based on user cognition to improve both the content and presentation of retrieval systems. taking powell’s city of books as an example, this paper proposes user feedback as first-hand user information. we will focus on (1) resource organizations based on user cognition and (2) new formats on search results based on knowledge recommendations. we will purposefully employ data from users’ own information and give knowledge back to users in accordance with the quote “of the people, for the people.” related work user cognition and measurement user cognition usually consists of a series of processes, including feeling, noticing, temporary memory, learning, thinking, and long-term memory.4 feeling and noticing are at an inferior level, while learning, thinking, and memory are comparatively superior. researchers have so far tried to identify user cognition processes by analyzing user needs. there are four levels of user needs according to ma and yang5 (see figure 1.) in turn, user interests normally reflect potential user needs. users who retrieve information on their own show feeling needs. users who give feedback show expression needs. users who ask questions show knowledge needs, which is the highest level. the methods to quantify user cognition require visible and measurable variables. existing studies have commonly used website log analysis or user surveys. website log analysis has been proven to be a solid data source to record and analyze both user interests and information needs.6 user surveys, including online questionnaires and face-to-face interviews, have been widely used to comprehend user feelings and user satisfaction.7 user surveys generally measure two kinds of relationship: between users and digital services and between users and the digital community.8 with a survey, we can make the most of statistics and assessment studies to analyze user satisfaction about an array of standards and systems of existing service platforms, service environments, service quality, and service personnel, which provides some references and suggestions for future study of user experience quality, platform elements, interaction process , and more.9 however, neither log data nor surveys can obtain first-hand user information in reallife settings. eye tracking and the concept-map method can be used to understand user behavior in the course of user testing.10 however, these approaches are difficult to adapt to a large group of users. therefore, a linguistic-oriented review analysis has become an increasingly important method. user content, including reviews and tags, could be analyzed through text mining and become valuable data sources to learn their preferences for the product and service in the areas of electronic commerce and digital libraries.11 this type of data has been called “more than words.”12 information technology and libraries | september 2018 68 figure 1. understanding user cognition by analyzing user needs. user-oriented knowledge service model the user-oriented service model includes user demand, user cognition, and user information behavior. a service model based on user demand chiefly concentrates on the motives, habits, regularities, and purposes of user demand to identify the model of use demand so that the appropriate service is adopted.13 service models based on user cognition attach importance to the process of user cognition, the influence that users are facing,14 and the change of library information services under the effects of series of cognitive processes (such as feeling, receiving, memorizing, and thinking).15 a service model based on user information behavior focuses on interactive behavior in the process of library information services that users participate in, such as interactions with academic librarians, knowledge platforms,16 and others. studies have paid more attention to the pre-process of the user-oriented service model, which analyzes information habits and user behaviors.17 studies have also proposed frameworks of knowledge services, design innovations,18 or personalized systems and frames of the knowledge service model, but they have not succeeded in implementing or performing user testing. knowledge service system construction most studies of knowledge service system construction are in business areas. numerous studies have explored knowledge-innovation systems for product services.19 cheung et al. proposed a knowledge system to improve customer service.20 vitharana, jain, and zahedi composed a knowledge repository to enhance the knowledge-analysis skills of business consultants.21 from of the people, for the people | lou, wang, and he 69 https://doi.org/10.6017/ital.v37i3.10060 the angle of user demand, zhou analyzed the elements of service-platform construction and found that crucial platforms should serve knowledge service system construction. 22 scholars proposed basic models for knowledge management and knowledge sharing, but they did not simulate their applications.23 knowledge management from the library-science perspective is very different from that in the business area. library knowledge management usually refers to a digital library, especially a personal digital library.24 others explore and attempt to construct a personalized knowledge service system,25 while fewer studies about system designs are based on the results of user surveys in accordance with documented surveys. we rarely see a user-feedback study combined with the method of using users’ own knowledge. users themselves know what they desire. if user-oriented studies separate the system design from user-needs analysis or the other way around, the studies may miss the purpose. therefore, we propose a resource-organization method based on users’ own knowledge to close the distance between the users and the system. resource-organization model based on user cognition there are normally two ways to construct a category system. one method gathers experts to determine categories and assign content to them; the category system comes first and the content second. the other method is to derive a category tree from the content itself, as we propose in this paper. in this way, the content takes priority over the categorization system. in this paper, we focus on this second way to organize resources and index content. resource organization requires a series of steps, including information processes, extraction, and organization. figure 2 shows the resource-organization model based on user cognition. this model fits the needs of digital resources with comments and reviews. the model has two interrelated parts. one is for indexing the content, and the other is for knowledge recommendations. for the first part, the model integrates all the comments and reviews of all literature in an area or the whole resource. the core concepts and the relationships among the concepts are extracted through natural language processing. the relationships between concepts are either subordination and correlation. a triple consists of two core concepts and their relationship. the triple set includes all triples. next, all books are indexed by taxonomy in the new category system. however, the indexing of every book is not based upon the traditional method, which is to manually determine each category by reading the literature. we use a method based on the books’ content. while we are extracting the core concepts from all books we extract the core concepts from every book by the same semantic-analysis methods and build up triples for the individual book. then the triples of this book can match the triple set in the new category system. once a triple in a single book yields a maximum matching value, the core concepts in the triple set will be indexed as the keywords of the book. a few examples of the matching process will be discussed in the empirical study (in the section “indexing books”). the first part is about comments and reviews, which are unstructured data. the second part is to make use of structural data in the bibliography to build a semantic network. structural data, including titles, keywords, authors, and publishers, is stored separately. we calculate the information technology and libraries | september 2018 70 informetrics relationships among the entities. the relationships can be among different entities, such as between one author and another or between an author and a publisher. then two entities and their relationship compose a triple. the components in triples are linked to each other, which makes them semantic resources. furthermore, the keywords in structural data are not the original keywords before the new category system but are the modified keywords. finally, the reindexed resources (books in the new category) and semantic resources (the triples from structural data) are both used to build the knowledge network. figure 2. resource-organization model based on user cognition. however, why is it important to use both unstructured data and structural data? the reason is to complete the entire content of a literature resource. neither of them can fully represent the whole semantics for a literature resource. structural data lacks subjective content, and unstructured data lacks basic information. thus, a full semantic network can be built using both kinds of data. of the people, for the people | lou, wang, and he 71 https://doi.org/10.6017/ital.v37i3.10060 resource-organization experiment object selection located in portland, oregon, powell’s city of books (hereafter referred to as “book city”) is one of the largest bookstores in the united states, with 200 million books in its inventory. book city caught our eyes for four reasons. (1) the comments and reviews of books on book city’s website are well constructed and plentiful. the national geographic channel established it as one of the ten best bookstores in the world.26 atlantis books, pendulo, and munro's books are also on the list. among these bookstores, only book city and munro’s books have indexed the information of comments and reviews. since user reviews are fundamental to this study, we restricted ourselves to bookstores that provided user reviews. (2) we excluded libraries because literature resources have been well organized in libraries. it might not be necessary to reorganize them according to user cognition. however, we can put this topic in the future study. (3) book city is a typical online bookstore that also has a physical bookstore. unlike amazon, book city, indigo, barnes & noble, and munro’s books have physical bookstores. however, they all have technological limitations on retrieval-system and taxonomical construction compared to amazon. thus, it is necessary to investigate these bookstores’ online systems and optimize them. (4) the location was geographically convenient to the researchers. the authors are more familiar with book city than other bookstores. moreover, we plan on conducting a face-to-face interview for the user study. it is doable only if the authors can get to the bookstore and the users who live there. in all, we choose book city as a representative object. data collection and processing on december 22, 2015, we randomly selected the field “cooking and food” and downloaded bibliographic data for 462 new and old books that included title, picture, synopsis and review, isbn, publication date, author, and keywords. in our previous work we described how metadata for all kinds of literature can be categorized into one of three types: structural data, semistructural data, and unstructured data.27 (see table 1). title, isbn, date, publisher, and author are classified as structural data. titles can be seen as structural data or unstructured data depending on the need. titles will be considered as an indivisible entity in this paper as titles need to retain their original meanings. keywords are considered as semistructural data for two reasons: (1) normally one book is indexed with multiple keywords, which are natural language; and (2) keywords are separated by punctuation. each keyword can individually exist with its own meaning. however, in the current category system, keywords are the names of categories and subcategories. since we are about to reorganize the category system, the current keywords will not be included in the following steps. we use the field “synopsis and review” in the downloaded bibliographic records as the source of user cognition. synopses and reviews are classified as unstructured data. all synopses and reviews of a single book are first incorporated into one paragraph, since some books contain more than one review. structural data will be stored for constructing a knowledge network. unstructured data will be part-of-speech tagged and word segmented by the stanford segmenter. all the books’ metadata are stored into the defined three data types and separate fields. each field is linked by the isbn as the primary key. information technology and libraries | september 2018 72 category organization first, the frequencies of words in all books are separately calculated after word segmenting so that core concepts are identified by the frequencies of words. in total, 29,370 words appeared 43,675 times, after excluding stop words. the 206 words in the sample that occurred more than 105 times appeared 34,944 times. this subset was defined as the core words according to the pareto principle. table 1. data sample. field content data type title a modern way to eat: 200+ satisfying vegetarian recipes structural data

london-based food stylist and writer anna jones. how we want to eat is changing. more and more people cook without meat several nights a week and are constantly seeking to . . . unstructured data we are inspired by zhang et al., who described a linguistic-keywords-extraction method by defining multiple kinds of relationships among words.28 the relationships include direct relationship, indirect relationship, part-whole relationship, and related relationship. • direct relationship. two core words have a relationship directly to each other. • indirect relationship. two core words are related and linked by another word as a media. • part-whole relationship. the “is a” relation. one core word belongs to the other. it is the most common relationship in context. • related relationship. two core words have no relationships but they both appear in a large context. the first two relationships can be mixed with the second two relationships. for instance, a partwhole relationship can have either a direct relationship or an indirect relationship. for this study, we combined every two core words into pairs for analysis. for example, the sentence “a picnic is a great escape from our day-to-day and a chance to turn a meal into something more festive and memorable” would result in several core-word pairs, including of the people, for the people | lou, wang, and he 73 https://doi.org/10.6017/ital.v37i3.10060 “picnic” and “meal,” “picnic” and “festive,” and “meal” and “festive.” for “picnic” and “meal,” there is an obvious part-whole relationship in this context. we observed all their relationships in all books and determined their relationship as a direct part-whole relationship because 67 percent of their relationships are part-whole relationship, 80 percent are direct relationship, and others are related relationship. this is the case when two core words are in the same sentence. for two words in different sentences but within one context, we define the words’ relationship as a sentence relationship. for example, “ingredient” and “meat” in one review in table 1 have an indirect relationship because they are connected by other core concepts between them. therefore, the relationship between “ingredient” and “meat” is an indirect part-whole one in this context. for other cases, two concepts are either related if they appear in the same context or are not related if they do not appear in the same review. thus, all couples of concepts are calculated and stored as semantic triples. figure 3. parts of a modified category in “cooking and food” based on user cognition. the next step is to build up a category tree (figure 4). a direct part-whole relationship is that between a parent class and child class. an indirect part-whole relationship is the relationship between a parent class and a grandchild class. a related relationship is the relationship between sibling classes. information technology and libraries | september 2018 74 compared to the modified category system (figure 3), the current hierarchical category system (figure 4) has two major issues. first, some categories’ names are duplicated. for example, the child class “by ingredient” contains “fruit,” “fruits and vegetables,” and “fruits, vegetables, and nuts.” second, there are categories without semantic meaning, such as “oversized books.” these two problems brought out disorderly indexing and recalled many irrelevant results. for example, the system would let you refine your search first if you type one word in search box. however, refining is confusing by parent class and children class. searching “diet” books as an example, the system suggests you refine your search from five subcategories of “diet and nutrition” under three different parent classes. however, the modified category system has avoided the duplicated keywords. furthermore, the hierarchical system based on users’ comments maintains meaning. figure 4. parts of current category system in “cooking and food.” indexing books we found that the list of keywords was confusing due to the inefficiency of the previous category system. it is necessary to re-index the keywords of each book based on the modified category system. we stand on the data-oriented indexing process. the method to detect the core concepts of each book is the same as that for all books in section 4.3. taking the book a modern way to eat as an example, triples are extracted from the book, including “grain-direct part whole-ingredient,” “nut-direct part whole-ingredient,” “vegetarian-related-health,” and so on. using all triples of the book to match with the triples set from all books in section 4.3, we index this book to categories by the best match parent class. in this case, 5 out of 9 triples of a modern way to eat are matched with the parent class “ingredient.” another two are matched with “natural” and “technique,” and of the people, for the people | lou, wang, and he 75 https://doi.org/10.6017/ital.v37i3.10060 the other two cannot correctly match with the triples set. then, a modern way to eat will be indexed with “cooking and food-ingredient,” “cooking and food-natural,” and “cooking and food-technique.” 4.5 semantic-resource construction the semantic resource is constructed based on structural data that was prepared at the beginning. the informetrics method (specifically co-word analysis) will be used to extract the precise relationship among the bibliography of books, as we previously proposed.29 we construct all structural data together and conduct co-words matrixes between each title, publisher, date, author, and keyword. for example, the author “anna jones” co-occurred with many keywords to varying degrees. the author co-occurred with the keyword “natural” four times and “person” seven times. according to qiu and lou, the precise relationship needs to be divided by the threshold and formatted as literal words.30 therefore, among the degree of all relationships between “anna jones” and other keywords, the relationship between “anna jones” and “natural” is highly correlated, and the relationship between “anna jones” and “person” is extremely correlated. triples are composed of two concepts and their relationships. then a semantic resource is finally constructed that could be used for knowledge retrieval. figure 5. an example of the knowledge network. once the semantic resource is ready, the knowledge network is presentable. we adopted d3.js to display the knowledge network (figure 5). the net view automatically exhibits several books related with an author william davis, which is placed in a conspicuous position on the screen. the forced map can be reformed when users drag any book with the mouse, which will be the noticeable center of other books. the network can connect with the database and the website. information technology and libraries | september 2018 76 5. user-experience study on knowledge display and recommendation there are two common ways to evaluate a retrieval system. one is to test the statistic results, such as the recall and precision. the other is a user study. since our aim is “of the people, for the people,” we chose to conduct two user-experience studies over the statistical results. as such, we can obtain what users suggest and comment on our approach. user-experience study design in february 2016, with the help of friends, we recruited volunteers by posting fliers in portland, oregon. fifty volunteers contacted us. thirty-nine responses were received by the end of march 2016 because the other eleven volunteers were not able to enroll in the electronic test. since we needed to test the feasibility of both the new indexing category and the knowledge recommendation, we set up the user study into two parts, including the comparison of the simple retrieval and the knowledge recommendation. first, we requested permission to use the data source and website frame from book city. however, we cannot construct a new website for book city due to intellectual-property issues. therefore, we constructed a practical mock-up to guide users to simulate a retrieval experiment. following the procedure of the user experience design, we chose mockingbot (https://mockingbot.com) as the mock-up builder. mockingbot allows the demo users to experience a vivid system that will be developed later. the mock-up supports every tag that can be linked with other pages so that subjects could click on the mock-up just as they would on a real website. the demo is expected to help us (1) examine whether our changes would meet the users’ satisfaction and (2) gather information for a better design. then we performed face-to-face, userguided interviews to first gain experience on the previous retrieval system and then compare them with our results. we concurrently recorded the answers and scores of users’ feedback. in the following sections, we will describe the interview process and present the feedback results. study 1: comparison of simple retrieval first, subjects were asked to search related books written by “michael pollan” at powells.com (figure 6). as such, all subjects used the search box based on their instincts. then they were asked to find a new hardcover copy of a book named cooked: a natural history of transformation. we paid attention to the ways that subjects located the target. only five of them used keyboard shortcuts to find the target. however, thirteen subjects stated their concerns regarding the absence of refinement options. furthermore, we noticed that six subjects swept (moused over) the refinement area and then decided to continue eye screening. in the meantime, we recorded the time they spent looking for the item. after they found the target, all subjects gave us a score from one to ten that represented their satisfaction with the current retrieval system. of the people, for the people | lou, wang, and he 77 https://doi.org/10.6017/ital.v37i3.10060 figure 6. screenshot of retrieval results in the current system. in the comparison experiment, we placed our mock-up in front of subjects and conducted the same exam above. in the mock-up, we used the basic frame of the retrieval system but reframed the refinement area. in the new refinement area (figure 7), we added an optional box with refinement keywords in the left column to narrow the search scope. the logic of the refined keywords comes from the indexing category, as we mentioned in the section on the indexing books. “michael pollan” was indexed in six categories: “biographies,” “children’s books,” “cooking and food,” “engineering manufactures,” “hobby and leisure,” and “gardening.” thus, when subjects clicked the “cooking and food” category, they can refine the results to only twelve books rather than the seventy books in the current system. users can obtain accurate retrieval results faster. after the subjects completed their tasks, they gave us a score from one to ten representing their satisfaction with the modified retrieval system. figure 7. refinement results in the modified category-system mock-up. information technology and libraries | september 2018 78 study 2: knowledge recommendation in this experiment, we conducted two tests for two functions on knowledge visualization. one tested the preferences for the net view, and the other tested the preferences for the individual recommendation. for the net view, we guided subjects to search for “william davis” in the mock-up and reminded them to click the net view button after the system recalled a list view. then, the subjects could see the net view results in figure 5. we recorded the scores that they gave for the net view. as for the recommendation on individual books, we adopted multiple layers of associated retrieval results for every book. users could click on one book and another related book would show in a new tab window. we asked subjects to conduct a new search for “william davis.” then they could browse the website and freely click on any book. once they clicked on davis’s book wheat belly: lose the wheat, lose the weight, and find your path back to health, the first recommendation results popped up (figure 8). the recommendation results about wheat in the field of “grain and bread” showed up, including good to the grain: baking with whole grain flours and bread bakers apprentice: mastering the art of extraordinary bread. others about health and losing weight showed up also, such as paleo lunches and breakfasts on the go. all related books appeared because the first book is about both wheat and a healthy diet. a new window showing relevant authors and titles would pop up if the mouse glided over any picture. we asked the subjects about their thoughts on the new recommendation format and recorded the scores. figure 8. an example of knowledge recommendation. users’ feedback as a result, knowledge organization and retrieval received a positive response (tables 2 and 3). first, subjects complained about the inefficiency of the current retrieval system in that it took so long to find one book without using shortcut keys (ctrl-f). three quarters of them were not satisfied with the original search style due to the search time length. however, 67 percent of the subjects gave a score of more than eight points for the refined search results of our new system. of the people, for the people | lou, wang, and he 79 https://doi.org/10.6017/ital.v37i3.10060 only two of them thought that it was useless since they were the two users who only took ten seconds to target the exact result. second, 67 percent and 74 percent of the subjects, respectively, thought that the knowledge recommendation and net view were useful and gave them six points. however, five subjects gave scores of one point because they maintained that it was not necessary to build a new viewer system. table 2. the time to find the

visualization of the retrieval results, using words such as “innovative” and “creative.” for instance, user 11 said, “bravo changes for powell, that’d be the most innovative experience for the locals.” among the subjects who gave scores of more than six points, the comments were mostly “interesting idea.” for instance, user 17 commented, “this is an interesting idea to explore my knowledge. i had no idea powell could do such an improvement.” some users offered suggestions to improve the system. for example, user 12 suggested that the system was not comprehensive enough to confidently assess whether the modified category system was better than the previous system. user 25 (a possible professional) was very concerned about the recall efficiency since the system might use many matching algorithms. discussion and conclusion in this paper, a digital literature resource organization model based on user cognition is proposed. this model aims to make users exert subjective initiative. we noticed a significant difference between the previous category system and the new system based on user cognition. our aim, which was “of the people, for the people,” was fulfilled. taking powell’s city of books as an example, it is purposeful to describe how to construct a knowledge network based on user cognition. the user experience study showed that this network implements an optimized exhibition of a digital-resource knowledge recommendation and knowledge retrieval. although user cognition includes many other processes of user behavior, we only used the literal expression. it turned out to be a positive and possible way to reveal users’ cognition. information technology and libraries | september 2018 80 we find that there is much more space for the construction object of digital resource knowledge recommendation based on user cognition. for one, in this paper we only take the familiar book city as a study object and books as experiment objects and determined favorable positive effects, which indicates that the digital resource knowledge link can be applied to physical libraries and bookstores or other types of literature. even though libraries have well-developed taxonomy systems, they can be compared with or combined with new ideas. for another, users adore visual effects and user functions. the results show promise in actualizing improvements to book city’s website or even to other digital platforms. the concerns will be how to optimize the retrieval algorithm and reduce the time costs in the next study.

improve the member experience, we have a couple of new groups getting down to work. lita local task force i'm writing this shortly after returning from lita forum 2015, which was a fantastic meeting. i'm glad that so many people were able to attend, and i hope even more will come to forum 2016. but we know many members cannot regularly travel to national meetings, and even the best online experience can lack the serendipitous benefits that so often come from face-to-face meetings. the new lita local task force will be responsible for creating a toolkit to facilitate local groups’ ability to host events, including information on event planning, accessibility, and ensuring an inclusive culture at meetings. so you’ll be able to host a lita event in your own backyard! (if your backyard has a couple of meeting rooms and good wireless.) forum assessment and alternatives task force as we begin work on lita local events, we are also turning our eyes to our national meeting. planning the next lita forum is essentially a year-round process. we assess the work we’ve done on previous forums, of course, but the annual schedule often doesn’t afford an opportunity to strategically rethink what forum is and how it can best serve the members. to address that issue, we’re convening another new task force, on forum assessment and alternatives. this group will look critically at how forum advances our strategic priorities, and will also look at other library technology conferences to help identify how forum can continue to distinguish itself in a rapidly changing environment. lita personas task force finally, as i write this, the board is in the final stages of creating a personas task force as a tool for better understanding our current and potential new members. a well-constructed set of personas, representing both people who are lita members and people who aren’t—but who could be or should be—will become a valuable tool for membership development, programming, communications, assessment, and other purposes. each of these task forces will work throughout 2016 and deliver their results by midwinter 2017. it is worth noting that we could only convene these groups because we have a strong list of volunteers on tap. if you haven’t filled out a lita volunteer form recently, please considering doing so at

september 1974 issue of jola, the "highlights of isad board meeting" reflects the library automation community's growing concern with misrepresentation of products and misleading or fraudulent claims. a proposal was made that isad create a mechanism to monitor relevant advertising in order to inform and protect' its constituency and, indeed, the entire profession. it is paradoxical that this concern is being voiced at a time when the relationship between the public and private sectors seems closer than at any other time in the recent past. in general, librarians and vendors are good friends. there is an atmosphere of mutual respect, and we no longer raise eyebrows upon learning that a librarian-colleague has gone "commercial." indeed, librarians and libraries are learning from the business world to create products and market them in order to support desired internal services. the growing entrepreneurial efforts of libraries are linkirig the two groups with a yet firmer bond. unfortunately, but inevitably, there are a few flies in the ointment. with regularity, we pick up professional literature to find advertising which sounds too good to be true. an investigation will usually indicate that, in fact, it is not true. we are often visited by salesmen describing incredible advances in their particular areas. the pressure applied by these people can be distasteful and even intolerable. or we may receive a onepage brochure from an unknown company, touting its latest, very competitive system, and listing the familiar names of well-respected librarians as advisors. almost always, we are lucky and are able to discover for ourselves the true nature of the products being advertised. our misfortune may begin when an ambitious salesman finds his or her way into the office of an administrator or politician who does not have adequate preparation for the onslaught of facts, figures, and fallacies. what are the best ways of misrepresenting a product? most approaches fall into one of the following categories: ( 1) misleading advertising, with unclear statements and imprecise use of vocabulary; ( 2) claims that one, or several, or many other libraries are using the product with satisfaction (when this indeed is not the case); ( 3) specific statements that a large and prestigious library is about to sign a contract for servic~s or products (although investigation will reveal no such intention); ( 4) lists of experts in the field who are presumed to be associated with the company in an advisory or consultant role (but who are unaware of this use of their names); and ( 5) approaches to federal, state, or local agencies to appeal 248 journal of library automation vol. 7/4 december 1974 the procedures used by libraries in requesting bids or awarding contracts. at this point, a note of caution must be inserted. strategies of advertising and marketing usually involve one or more of the above techniques to a certain extent. we all practice minor exaggerations and simplifications in our professional lives in order to accomplish certain goals. it would be unwise and unfair to accuse an advertiser of misleading his market on the basis of one of these "small exaggerations." in resolving this issue, our concern must be with those individuals or organizations who are constantly found with a large discrepancy between the word and the deed. what methods can be used as protection against these tactics? there are several reliable paths: ( 1) be aware of and alert to the possibilities of misleading claims and misrepresentation; ( 2) follow up a sales pitch with a few phone calls to those institutions that are described to be using the product or about to sign the contract; ( 3) maintain a reasonable amount of resistance to the sales talk; ( 4) use the library profession's invisible college to determine the validity of the claims and the experiences that others have had with the firm; and ( 5) support the attempts of our professional societies, such as ala and asis, to require organizations to maintain certain advertising standards. the library market is expanding and maturing; therefore, these growing pains associated with increased marketing efforts are not unexpected. with adequate education and awareness on the part of the buyer, with some pressures placed on advertisers by the professional community, and with a tolerance for the normal tendencies of advertising and marketing, we will be able to resolve a difficult situation with grace and without hard feelings. susan k. martin reproduced with

and libraries; mar 2000; 19, 1; proquest pg. 34 one-stop place for presenting scholarly research. staff support includes consultation in any aspect of the bailiwick project, including design issues, interface development, and training in software. staff members do not provide programming nor do they do any work in researching or assembling sites. each faculty member is assigned an information arcade consultant at the point of submitting a bailiwick application. the consultant serves as a primary contact person for technical support, troubleshooting, basic interface design guidance, and referrals to other staff both in the libraries and on campus. at present, the current level of staffing has been sufficient to accommodate this sort of assistance, which is not unlike the assistance provided to any patron who walks in the door of the information arcade. as a computing facility, the information arcade provides public access to a host of multimedia development workstations for scanning images, slides, and text, and for digitizing video and audio. at these multimedia stations, a large suite of multimedia integration software and web publishing software is made available for public use. staff at the public services desk have a strong background in multimedia development and web design and can provide some one-on-one training on a walk-in basis beyond technical support and troubleshooting. all of these hardware and software resources are available to bailiwick content providers, who can choose to do their development work in the information arcade or at their home or office. finally, since there is a close relationship between the information arcade and the university libraries web site, system administration and web server support is all handled inhouse as well. there are few artificial barriers imposed by the technology, thereby permitting content providers to focus on their creative expression and scholarly work. with only minimal reallocation of existing resources, the university of iowa libraries has been able to launch the bailiwick project and continue to develop it at a modest pace. one of the components most essential for its continued success, however, is the ability to scale up to meet the expected demand over the next several years. technical infrastructure challenges are not overwhelming as yet. an analysis still needs to be made to determine how quickly creators are developing their sites, what the implications are for network delivery of these resources, what reasonable projections there are for disk space, and who is using the resources. perhaps more importantly, though, adequate staffing will always remain a concern. some faculty wish to work more closely with library staff consultants than time allows, and the consultants would certainly find it enriching to be more intimately involved with the development of each bailiwick site. marketing of the bailiwick project has been discrete (to say the least) because of the limited staffing available. however, embedded in the collaboration inherent in bailiwicks is the potential for stronger involvement with faculty in obtaining grant funding to support the development of specific bailiwick sites. a model for research libraries bailiwick is a project that allows the university of iowa libraries, and specifically the information arcade, to focus on the integration of technology, multimedia, and hypertext in the context of scholarship and research. to date, most of the bailiwick sites represent disciplines in the arts, humanities, and social sciences. this matches the overall clientele of the information arcade (given its location in the university of iowa's main library), but it also reflects the fact that these disciplines have been tradi34 information technology and libraries i march 2000 tionally undersupported with respect to technology. nevertheless, individual faculty in these disciplines have integrated some of the most creative applications of the technology in their everyday teaching and research, in part because of the existence of the information arcade and the groundwork laid by the libraries for the past several years. with the information arcade's visibility on campus, and with similar resources and support in the information commons-a sister facility in the hardin library for the health sciences-the university of iowa libraries are well regarded on campus as a leader in information technology, electronic publishing, and new media. thus, faculty and students alike are accustomed to turning to the libraries for innovation in technology and the bailiwick project is a natural fit. bailiwick is now fully integrated as part of a palette of new technology services and scholarly resources included within the libraries' support of teaching, learning, and research at the university of iowa. engelond: a model for faculty-librarian collaboration in the information age scott walter the question of how best to incorporate information literacy instruction into the academic curriculum has long been a leading concern of academic librarians. in scott walter (walter.123@osu.edu), formerly humanities and educaton

prohibited without permission. recent years, this issue has grown beyond the boundaries of professional librarianship and has become a general concern regularly addresssed by classroom faculty, educational administrators, and even regional accrediting organizations and state legislatures. this essay reports on the success of a pilot program in course-integration information literacy instruction in the field of medieval studies. the author's experience with the "enge/and" project provides a model for the ways in which information literacy instruction can be effectively integrated into the academic curriculum, and for the ways in which a successful pilot program can both lead the way for further development of the general instructional program in an academic library, and serve as a springboard for future collaborative projects between classroom faculty and academic librarians. in 1989 the chronicle of higher education reported on the proceedings of a conference on teaching and technology held near the richmond, indiana campus of earlham college.1 conference speakers identified a number of concerns for those involved in teaching and learning at the end of the twentieth century. chief among these were recent advances in information technology that threatened "to leave students adrift in a sea of information." earlham college librarian evan i. farber and his fellow speakers called upon conference attendees to develop new teaching strategies that would help students learn how to evaluate and make use of the "masses of information" now accessible to them through emergent information technologies, and to embrace a collaborative teaching model that would allow academic librarians and classroom faculty members to work together in developing instructional objectives appropriate to the information age. the concerns expressed by these faculty and administrators for the information literacy skills of their students may have still seemed unusual to the general educational community in the late 1980s, but, as behrens and breivik have demonstrated, such concerns have been a leading issue for academic librarians for more than twenty years. according to its most popular definition, information literacy may be understood as "[the ability] to recognize when information is needed and ... the ability to locate, evaluate, and use effectively the needed information."2 it has become increasingly clear over the past decade that educators at every level consider information literacy a critical educational issue in contemporary society. perhaps the most frequently cited example of concern among educational policy-makers for the information literacy skills of the student body can be found in ernest boyer's report to the carnegie foundation, college: the undergraduate experience in america (1987), in which the author concludes that "all undergraduates should be introduced to the full range of resources for learning on campus," and that students should spend "at least as much time in the library ... as they spend in classes."3 but while boyer's report may be the most familiar example of such concern, it is hardly unique. as breivik and gee have described, a small group of educational leaders have regularly expressed similar concerns over the past several decades. moreover, as bodi et al. among others, have demonstrated, the rise in professional interest in information literacy issues among librarians in the past decade is closely related to more general concerns among the educational community, especially the desire to foster critical thinking skills among the student body. by the mid-1990s, professional organizations such as the national education association, accrediting bodies such as the middle states association of colleges and schools, and even state legislators began to incorporate information literacy competencies into proposals for educational reform at both the secondary and the post-secondary levels. the confluence over the past decade of new priorities in educational reform with rapid developments in information technology provided a perfect opportunity for academic librarians to develop and implement formal information literacy programs on their campuses, and to assume a higher profile in terms of classroom instruction. for the past two years, a pilot project has been underway at the miller nichols library of the university of missouri-kansas city that not only fosters collaborative relations between classroom faculty members and librarians, but promotes the development of higherorder information literacy skills among participating members of the student body. engelond: resources for 14th-century english studies (www.umkc.edu/lib i engelond/) incorporates traditional library instruction in information access as well as instruction in how to apply critical thinking skills to the contemporary information environment into the academic curriculum of participating courses in the field of medieval studies. our experience with the engelond project provides a model for the ways in which information literacy instruction can be effectively integrated into the academic curriculum, and for the ways in which a successful pilot program can both lead the way for further development of the general instructional program in an academic library, and serve as a springboard for future collaborative projects between classroom faculty members and librarians. the impetus for collaboration "most medieval web sites are dreck," or so wrote linda e. voigts, curators' professor of english at the university communications i walter 35 reproduced with permission of the copyright owner. further reproduction prohibited without permission. of missouri-kansas city, in a recent review of her participation in the engelond project for the medieval academy news. describing the impetus for the development of the project in terms of a complaint increasingly common among members of the classroom faculty, voigts provides a number of examples from recent years in which students made extensive, but inappropriate, use of web-based information resources in their academic research. in one example, voigts describes a student who made the mistake of relying heavily on what appeared to be an authoritative essay for her report on medieval medical practices. the report was actually authored by a radiologist "with little apparent knowledge of either the middle ages or of premodern medicine." "how can those of us who teach the middle ages," voigts asked, "help our students find in the morass of rubbish on the internet the relatively few pearls? how can we foster skills for distinguishing between true pearls and those glittery paste jewels that dissolve upon close examination?"4 by the time voigts approached the miller nichols library during the fall 1997 semester for suggestions about the best ways to teach her students how to "sift the web" in their search for resources suitable for academic research in medieval studies, the issue of faculty-librarian collaboration in internet instruction was a familiar one. in a representative review of the literature, jayne and vander meer identified three "common approaches" that libraries have taken to the problem of teaching students how to apply critical thinking skills to the use of web-based information resources: (1) the development of generic evaluative criteria that may be applied to web-based information resources; (2) the inclusion of web-based information resources as simply one more material type to be evaluated during the course of one's research (i.e., adding lo.st updated : 27.april 1999 ! enge/and supports the research of students in dr . linda ehrsam voigts' chaucer (english 4121512 ) and medieval literature ii (english 555a) courses at the university of miss ouri-k ansas city. the site was created by the university libraries' public services staff with the collaboration of dr . voigts . we hope it will serve as a prototype for future collaborative efforts integrating library resources, course content. and multi-media technologies these pages contain syllabi for both courses, links to internet resources (including web sites. news groups and online discussion groups relevant to medieval studies) . a guide to evaluating both online and print research tools. a list of materials held on reserve at miller nich ols library for the use of these classes. and links to the merlin library catalog and a wide range of databases available through the university libraries . audionisual resources include rea!audio streams of dr. voigts reading from chaucer's canterbury tales and troi/us and criseyde . also included is joshua merrill's 'from gatehouse to cathedral a phot ograp hic pilgrimage to chaucerian landmarks .' , ,~ • • i ~ i i ju l . • i t• ii i i i ' • "i h d1,t i lt.;l 1.,,ld~.;, ..,;,.,"' r'\uu,v i io 1.;:,u.ji .;l ,t.

instructional session); and (3) working with faculty to integrate critical thinking skills into an academic assignment that asks students to use or evaluate web-based information resources relevant to their coursework. 5 while the engelond project focused primarily on the last of these options, our work on the project also fostered the use of the first two approaches in our broader instructional program. engelond's landscape the engelond web site provides access to a number of resources for participating students. these resources may be categorized as course-specific (e.g., course syllabi), information literacyrelated (e.g., a set of evaluative criteria for use with web-based information resources), or multimedia (e.g., sound recordings of voigts reading excerpts from chaucer's works in middle english). all of these resources are accessible from the engelond home page www.umkc.edu/lib/engelond/) (see figure 1). several links are also provided throughout the site to resources housed on the library's web site, including access to electronic databases and subject-specific guides to relevant resources in the print collection. although students make use of all of these resources during the course of the semester, the emphasis in this essay will be on describing the nature and use of the information literacy-related resources. as behrens and euster have noted, recent interest in information literacy instruction has been guided to a degree by concern over student ability to make effective use of new forms of information technology. this concern is addressed in the engelond project by its "internet resources" page, through which students are acquainted with the architecture of the internet and are provided with annotated references (and links) to a number of electronic resources (including web portals) that will allow them to begin their research in medieval studies. students making use of the page are 36 information technology and libraries i march 2000 reproduced with permission of the copyright owner. further reproduction prohibited without permission. introduced, for example, to a variety of the different types of information resourc e s available through the internet, including web sites, telnet sites, news groups, and discussion lists. users are also directed to related resources on the library web site, including a guide to print resources for the study of chaucer and an annotat ed guide to web-based information resources generally useful for the study of literatur e . 6 also provided on the engelond site is a discussion of evaluative criteria that students might apply to their selection of web-based information resources for academic research. designed to address voigts' initial concern about the issue of teaching students how to apply critical thinking skills to their use of the web, the "criteria" page provides a general discussion of the nature of webbased information resources, the ways in which such resources differ from traditional resources, and the kinds of questions that students must ask of any web-based resource before making use of it in their academic work . reflecting the idea that information literacy skills are best taught in connection with a specific subject matter, the "criteria" page includes references to a number of illustrative examples of web-based resources in medieval studies. this page also reflects the evolutionary nature of the engelond project, since new illustrations are added as each successive group of student users discovers different examples (both positive and negative). also included on this page is a link to the library 's "quick reference guide to evaluating resources on the world wide web," a generic version of the criteria developed for use with the broader instruction program at the miller nichols library . 7 while the resources described above introduce students to the information landscape in the field of medieval studies and provide them with evaluative tools tailored to subject-specific concerns in making use of web-based information resources in their academic work, the final information literacy-related resource made available through the engelond site is perhaps of the greatest interest. the "class picks" page presents the results of participating students' web site evaluati on assignments. on this page , user s will find student evaluations of web-based resources in medieval studies that draw not only on the information literacy skills provided through traditional library instruction, but also on the subject-specific knowledge that students gain as part of their academic coursework. jayne and vander meer wrote that faculty-librarian collaboration in internet instruction is most effective when students are asked to draw both on generic informational literacy skills and on information and evaluative criteria specific to the subject matter being addressed.8 as they concluded, " [to] benefit fully from the web's potential, stud ents need training and guidance from librarians and faculty." incorporating discussions of site design, organization of information, and veracity of content, the web site evaluations found on the "class picks" page demonstrate that participating students have learned both from the librarian and the scholar, and hav e begun to consider the best ways to incorporate web-based information resources into their day-to-day academic work. in a review of "the harvard chaucer page " (http:/ / icg.fas. harvard .edu / -chaucer /) , for example, students note the general appeal of the site, but criticize it both for technical problems in its design and for editorial choices that limit its utility for academic research: the harvard chaucer is an insightful , colorful look at the author and his times, but is dappled conspicuously with misspellings, repeated phrases , sentence fragments, broken links, and unfinished pages . translations of medieval texts provided on the site are often anonymou s, making it hard to tell if the translation is credible and an acceptable resourc e for serious research in chauce r studies. if one is interested in pursuing a topic found on the harvard chaucer , s / he is well advised to explore the site for ideas and background information, but to go elsewhere for authoritative sources .. . 9 in another review , this one of "the medieval feminist index" (www.haverford.edu / library/ reference/mschaus/mfi/mfi.html), students provide a discussion of the scholarly authority of the site as well as a description of the results retrieved in sample searches of the index for materials relevant to the study of chaucer. 10 the review concludes with further examples of issues relevant to chaucer studies that might be effectively investigated with information identified through this resource. in both reviews, students demonstrate the ability to critically evaluate a web site both for its design and for its content , and the ability to express the strengths and weaknesses of a site from the point of view of a student concerned with how to make use of a web-based information resource in his or her academic work. as a result, the reviews found on the "class picks" page not only demonstrate the successful approach to course-integrated information literacy instruction promoted through the engelond project, but also provide a useful student resource in their own right. the collaborative approach in her review of faculty-librarian partnerships in information literacy instruction, smalley wrote that, in the best-case scenario, "the student gains communications i walter 37 reproduced with permission of the copyright owner. further reproduction prohibited without permission. mastery in using some portion of internet resources, as well as exposure to resources intrinsically important to disciplinary pursuits. in doing the web-based exercises, students see information seeking and evaluation as essential parts of problem solving within the field of study." 11 the three information literacy-related resources found on the engelond site"internet resources," "criteria, " and "class picks" -demonstrate one approach to providing course-integrated information literacy instruction in such a way that the classroom faculty member and the academic librarian can work collaboratively and productively to meet their mutual instructional goals . both the classroom faculty member and the cooperating librarian are able to meet their instructional goals using the engelond model because of the collaborative nature of the information literacy instruction provided to the participating students. students enrolled in voigts' chaucer class during the winter 1999 semester received information literacy instruction focused both on information access and critical thinking while completing successive iterations of the web site evaluation assignment required for the course. a brief overview of the collaborative teaching process should suggest ways in which the participating faculty member and librarian were able to draw successfully both on generic information literac y skills and on subjectspecific knowledge while conducting course-integrated library instruction using the engelond site. participating students during the winter 1999 semester began with a general introduction to the electronic resources available through the miller nichols library at the university of missouri-kansas city (e.g., using the online catalog and databases such as the mla bibliography) . students were then presented with an introduction to the problem of applying critical thinking skills to the use of web-based information resources, as described on engelond's "criteria" page. following this introductory session conducted by the cooperating librarian, the cooperating faculty member provided students with a number of illustrative examples of the inappropriate use of electronic resources for academic research in medieval studies. from the beginning, the librarian and the faculty member modeled an integrated approach to the evaluation of information resources for their students; one that drew both on generic critical thinking skills and on specific examples of how such skills might be applied to resources in their field. following this initial session (which took place during the first week of the semester) , students were asked to complete an evaluation of a web site containing information they might consider using as part of their academic work. individual sites were chosen from among those accessible through the subject-specific web portals provided on the "internet resources" page. students were provided both with the library's "quick reference guide to evaluating resources on the world wide web" and with the more extensive description of web site evaluation available on the "criteria" page . students completed these initial reviews over the following week and submitted copies to both the faculty member and the librarian . in preparation for the second instructional session (which took place during the third week of the semester), the faculty member and the librarian evaluated each review twice (individually, and then together). reviews were evaluated for the clarity of their criticism of a site, both from the point of view of information organization and design and from the point of view of the significance of the information for student research in the field . sites that seemed to merit further review by the entire class were selected from 38 information technology and libraries i march 2000 this pool of evaluations and were discussed in greater detail by the instructors. the second instructional session took the form of an extended review of the sites selected in the meeting described above . in each case, students were asked to describe their reaction to the site in question. in cases where more than one student had evaluated the same site, each student was asked to present one or two distinct points from his or her review. the instructors then presented their reactions to the site. again, the librarian and the faculty member modeled for the students an approach to the critical evaluation of information resources that drew not only on the professional expertise of the librarian, but also on the scholarly expertise of the faculty member . by the end of this session, students had been exposed to three separate critiques of the selected web sites: the student's opinion of how the information presented on the site might be used in academic research; the librarian 's opinion of how effectively the information was organized and presented, and how its authority, currency, etc ., might differ from that of comparable print resources; and, finally, the faculty member's opinion of the place and value of the information provided on the site in the broader scheme of the discipline. following this session, the students were assigned to groups in order to develop more detailed evaluations of the web sites discussed in class. as before, these assignments were submitted both to the faculty member and to the librarian. after further review by both instructors, the assignments were returned to the students for a third (and final) iteration, and then mounted to the "class picks" page. by the conclusion of this assignment, participating students had learned not only how to apply critical thinking skills to web-based information resources, but had begun to think about the nature of reproduced with permission of the copyright owner. further reproduction prohibited without permission. electronic information and the many forms that such information can take. the web site evaluations included on the "class picks" page demonstrate the students' ability to successfully evaluate a web-based information resource both for its design and for its content, and to suggest the academic situations in which its use might be warranted for a student of medieval literature. evaluating engelond during the winter 1999 semester, we attempted to evaluate the success of the information literacy instruction provided through the engelond project. while the web site evaluations produced by the students provided one obvious measure of our instructional success, we attempted to learn more about the ways in which students used the materials provided through the engelond site by polling users and by examining use patterns on the site. both of these latter measures confirmed what the instructors already suspected: students enrolled in participating courses were making heavy use of the information literacy-related resources housed on the engelond site and saw the skills fostered by those resources as a valuable complement to the disciplinary knowledge being gained in the traditional classroom. as part of a general evaluation of the instructional services provided by the library during the course of the semester, students participating in the engelond project were asked open-ended questions such as: "what features of the engelond web site did you find most useful as a student in this course?"; "how did the existence of the engelond site and the collaboration between your classroom instructor and the library enhance your learning experience in this course?"; and "what aspects of the library instruction that you received as part of this course do you believe will be useful to you in other courses or in regards to lifelong learning?" among the specific items cited most often by students as being useful to them in their academic work were two of the information literacy-related resources: "internet resources" and "class picks." likewise , information literacy skills such as familiarity with the structure of the internet and the ability to critically evaluate web-based information resources were listed by almost every student as skills that would be useful both in other academic courses and in their daily lives . moreover, two graduate students who were participants reported that their experience with engelond had led them to incorporate information literacy instruction into the undergraduate courses that they taught themselves. any conclusions about the appeal of the information literacyrelated resources housed on the engelond site based on these narrative responses were reinforced by a study of the use statistics for the same period. through the first three months of the winter 1999 semester ganuary-march), the engelond site recorded approximately one thousand "hits" on its main page.12 in each month, the most frequently accessed pages were the three information literacy-related resources described above, with the "criteria" page regularly recording the greatest number of hits . among the other most-frequently visited pages on the site were the multimedia resource page (" audio -visual"), the "syllabi" page, and the "quick reference guide to chaucer" (housed on the library web site, but accessible through the "internet resources" page). taken in conjunction with the narrative responses provided on the evaluation form , these use statistics suggest that the information literacy resources provided through the engelond site have become a fullyintegrated, and greatly appreciated, feature of the academic curriculum in medieval studies in the department of english at the university of missouri-kansas city. a model for future collaboration the engelond project has not only been a success with students who have enrolled in participating courses, but has had a significant influence on the broader instructional program at the miller nichols library. it has served as a template for future collaborative efforts between the classroom faculty and the library in terms of integrating information technology and information literacy into the academic curriculum. in terms of the instructional program at the miller nichols library, our experience with engelond helped lay the groundwork for the development of new instructional materials and for new instructional programs . it was through engelond, for example, that we first provided electronic access to our point-of-service guides to library materials in various subjects (e.g., the "library guide to chaucer"). as of the end of the winter 1999 semester, we have made almost all of our pathfinders available on the library web site and are now considering ways in which these might be effectively incorporated into the work being done by our faculty in developing web-based coursework. also, it was through engelond that our subject specialists started collecting and annotating web-based information resources of potential use to our students and faculty. now, subject specialists are developing "subject guides" to web-based resources in a number of fields and promoting their use among faculty members who , like voigts, are concerned about the quality of the web-based information

web-based resources are available online (www. umkc.edu/lib /instruction/guides/ index.html). finally, the instructional session on the critical evaluation of webbased resources that has been the centerpiece of library instruction for the engelond project has now been adapted for inclusion in our normal round of instructional workshops. while support for such innovations in our instructional program clearly existed within the library prior to the initiation of the engelond project, the project's success has provided an important spur to the development of instructional services in the library. the commitment to collaborative instructional programming demonstrated by the engelond project has also helped pave the way for the development of the university of missouri-kansas city's new technology for learning and teaching (tlt) center. housed in the miller nichols library, the tlt center offers faculty workshops in the use of information technology and a place in which classroom faculty, subject specialists, and educational technologists may collaborate on the development of projects such as engelond. further information on the tlt center is available online (www.umkc.edu/tltc/) (see figure 2). initiating a culture of collaboration between members of the classroom faculty and academic librarians can be a difficult task (as so much of the literature has shown). in reviewing our experience with engelond, we have benefited from the suggestions that hardesty made some years ago about the means of supporting the adoption across campus of an innovative instructional model: (1) the librarian must present information literacy instruction in such a way that it does not threaten the role of the classroom faculty member as an authority in the subject matter of the course; (2) the new approach to instructional collaboration must be adopted on a limited basis at first, rather than requiring that all instructional programs immediately adopt the new approach; and (3) the results of a successful pilot projects 40 information technology and libraries i march 2000 must be "readily visible to others" on campus. 13 designed as a pilot project, engelond has successfully demonstrated that classroom faculty and academic librarians can collaborate to meet their mutual instructional objectives, both in terms of information literacy instruction and in terms of academic course content. as information technology continues to gain a central place in the educational mission of the college and university, it is likely that the sphere of mutual instructional objectives between classroom faculty and academic librarians will only increase. our careful approach to raising the instructional profile of librarians on campus has been rewarded, too, both by an increasing number of faculty members seeking course-related instruction in our electronic classroom as part of the regular instructional program of the library, and by the institutional commitment of resources to the tlt center, which will become the nexus of instructional collaboration between faculty and librarians on our campus. during the 1999-2000 academic year, no fewer than three academic courses in medieval studies will make use of the engelond site. as more faculty become aware of the services provided by the tlt center, such collaborative approaches to information literacy instruction will likely become more evident across a variety of disciplines. the lessons learned over the past two years of project development will be invaluable as we move to provide courseintegrated information literacy instruction to an increasing number of students in an increasingly broad variety of courses. acknowledgments the engelond project has benefited from the work of a number of individuals over the past two years, reproduced with permission of the copyright owner. further reproduction prohibited without permission. especially ted p. sheldon, director of libraries at the university of missouri-kansas city, and marilyn carbonell, assistant director for collection development, both of whom were instrumental in developing the plan for a pilot project in courseintegrated information literacy instruction with professor voigts. the design for the engelond site was developed by john laroe, former multimedia design technologist at the miller nichols library. the original text for the site was written by voigts, laroe, and t. michael kelly, former humanities reference librarian at the miller nichols library. additional text and resources for the site have been developed over the past year by voigts and myself. in addition, a number of librarians and staff members in the public services division of the miller nichols library devoted time to critiquing the site and to assisting with the creation of the embedded audio files. these contributions may not always be evident to the students who benefit from the project, but they were instrumental in our ability to successfully meet our instructional objectives during the 1998-99 academic year. references and notes 1. thomas j. deloughry, "professors are urged to devise strategies

the dire predictions about the end of paper and the book since microfiche was hailed as the savior of libraries decades ago. now it seems that technology may be finally catching up with the hype. with the amazon kindle and the sony reader beginning to sell in the marketplace despite the cost (about $360 for the kindle), it appears that a whole new group of electronic alternatives to the print book will soon be available for users next year. amazon reports that e-book sales quadrupled in 2008 from the previous year. this has many technology firms salivating and hoping that the consumer market is ready to move to digital reading as quickly and profitably as the move to digital music. some of these new devices and technologies are featured in the march 3, 2009, fortune article by michael v. copeland titled “the end of paper?”1 part of the problem with current readers is their challenges for advertising. because the screen is so small, there isn’t any room to insert ads (i.e., revenue) around the margins of the text. but new readers such as plastic logic, polymer vision, and firstpaper will have larger screens, stronger image resolution, and automatic wireless updates, with color screens and video capabilities just over the horizon. still, working out a business model for newspapers and magazines is the real challenge. and how much will readers pay for content? with everything “free” over the internet, consumers have become accustomed to information readily available for no immediate cost. so how much to charge and how to make money selling content? the plastic logic reader weighs less than a pound, is one-eighth of an inch thick, and resembles an 8½ x 11 inch sheet of paper or a clipboard. it will appear in the marketplace next year, using plastic transistors powered by a lithium battery. while not flexible, it is a very durable and break-resistant device. other e-readers will use flexible display technology that allows one to fold up the screen and place the device into a pocket. much of this technology is fueled by e-ink, a start-up company that is behind the success of the kindle and the reader. they are exploring the use of color and video, but both have problems in terms of reading experience and battery wear. in the long run, however, these issues will be resolved. expense is the main concern: just how much are users willing to pay to read something in digital rather than analog? amazon has been hugely successful with the kindle, selling more than 500,000 for just under $400 in 2007. and with the drop in subscriptions for analog magazines and newspapers, advertisers are becoming nervous about their futures. or will the “pay by the article” model, like that used for digital music sales, become the norm? so what should or do these developments mean for libraries? it means that we should probably be exploring the purchase of some of these products when they appear and offering them (with some content) for checkout to our patrons. many of us did something similar when it became apparent that laptops were wanted and needed by students for their use. many of us still offer this service today, even though many campuses now require students to purchase them anyway. offering cutting-edge technology with content related to the transmission and packaging of information is one way for our clientele to see libraries as more than just print materials and a social space. and libraries shouldn’t pay full price (or any price) for these new toys; companies that develop these products are dying to find free research and development focus groups that will assist them in versioning and upgrading their products for the marketplace. what better avenue than college students? related to this is the recent announcement by the university of michigan that their university press will now be a digital operation to be run as part of the library.2 decreased university and library budgets have meant that university presses have not been able to sell enough of their monographs to maintain viable business models. the move of a university press to a successful scholarly communication and open-source publishing entity like the university of michigan libraries means that the press will be able to survive, and it also indicates that the newer model of academic libraries as university publishers will have a prototypical example to point out to their university’s administration. in the long run, these types of partnerships are essential if academic libraries are to survive their own budget cuts in the future.

automated library system virginia m. bowden: systems analyst, the university of texas health science center at san antonio, and ruby b. miller: head cataloger, trinity university, san antonio, texas. 183 the marcive library system is a batch computer system utilizing both the marc tapes and local cataloging to provide catalog cal'ds, book catalogs, and selective bibliographies for five academic libra1·ies in san antonio, texas. the development of the system is traced and present procedures are described. batch retrieval from the marc 1·ecords plus the modification of these records costs less than twenty cents per title. computer costs fo1' retrieval, modification, and card production average six-ty-six cents per title, between seven and ten cents per card. the attributes and limitations of the marcive system are compm·ed with those of the oclc system. in san antonio, texas, a unique cooperative effort in library automation has developed, involving the libraries of five diverse institutions: trinity university, the university of texas health science center at san antonio (uthscsa), san antonio college (sac), the university of texas at san antonio (utsa), and st. mary's university. these institutions are utilizing the marcive library system which was developed by and for one library, that of trinity university. the marcive system is a batch, disc oriented computer system utilizing both local cataloging and the marc tapes to produce catalog cards, book catalogs, selective bibliographies, and other products. development the trinity university library has been involved in library automation since 1966.1 when the library reclassified its collection from dewey to the library of congress classification in1966, a simplified machine-readable format was developed and used for storage on computer. this format contained the following bibliographic elements: accession number, call number, author, title, and imprint date. in 1969 the library decided to reformat the computer data base into a marc ii compatible format in order 184 ] ournal of library automation vol. 7 i 3 september 197 4 to build a data base of bibliographic records that could be the basis for all future automated systems within the library. the resulting system, marcive, was designed jointly by the head cataloger, ruby b. miller, and the library programmer, paul jackson, a graduate student in trinity's department of computer science. since in 1969 literature on completed library automation projects was sparse, no other system was used as a guide. the marcive format was based on the designers' interpretation of the 1969 edition of the marc manual. the name, marcive, evolved when the programmer facetiously claimed that his format was so advanced he would call it the marc iv format. the computer room operating staff, ignoring the space between the marc and iv, combined the two, producing marciv. an e was added later for ease of pronunciation. the marcive system was designed initially as a system for data storage and retrieval. the update, select, and acquisitions list programs were operative in september 1970. the next month uthscsa inquired as to the possibility of producing catalog cards as part of the marcive system. within the brief span of three months, by january 1971, trinity university library produced 4,289 catalog cards and uthscsa produced 1,719 catalog cards via marcive. in february 1974, the five participating libraries produced a total of 29,000 catalog cards, with trinity accounting for 10,740 cards. continued development of the marcive system was delayed in 1971 by changes in computer center personnel and equipment. in 1972 new programs were developed to incorporate the marc tapes into the marcive system. the size of the marc data base, which is now held on three discs, was a major problem. modifications were included to accept input from magnetic tape and typewriter terminals using the apl language as well as keypunched cards. the original restriction of the system to classifications with one to three alphabetic letters followed by numbers, such as used by lc and nlm, was modified to accept dewey decimal classification to accommodate san antonio college. this restriction had been incorporated in an attempt to insure that the call number would be properly formatted, thus simplifying retrieval in the select program and grouping in the acquisitions list and update programs. computer configuration the marcive system is a disc oriented system which was programmed for an ibm 360/44 using the mft operating system. this computer model was designed for scientific programming and was manufactured in limited quantities. the programs were written in basic assembly language since adequate higher level language compilers for the 360 i 44 were not available at the trinity computer center. in 1971 the programs were converted to run under dos, and in 1972 they were converted for processing on the ibm 370/155 using the os processing system. since the initial promarcne/bowden and miller 185 grams were written in basic assembly language, the subsequent programs have also been written this way. marcive format the marcive format is an adaptation of the marc ii format. the definition of the marc ii format is a", .. format which is intended for the interchange of bibliographic records on magnetic tape. it has not been designed as a record format for retention within the files of any specific organization ... [it is] a generalized structure which can be used to transmit between systems records describing all forms of material capable of bibliographic descriptions . . . the methods of recording and identifying data should provide for maximum manipulability leading to ease of conversion to other formats for various uses."2 adaptation of the marc ii format is common among users. an analysis by the recon task force found much variation among the use of the fixed fields, tags, indicators, and subfields. 3 the oclc system can regenerate marc ii records from oclc records although they contain only 78 percent of the number of characters in the original marc ii record. 4 the developers of the marcive system studied the marc manual and decided that the leader and directmy were not necessary for program manipulation. such information can be generated by a conversion program. the marc mnemonic codes were chosen instead of the numeric ones because all bibliographic data were being coded locally and it was felt that mnemonics would be easier to work with. the mnemonic codes are the ones designated in the marc manuals except that "si" was substituted for "se." rules for assigning indicators, subfields, and delimiters are those described by marc. the basic structure of the marcive format is illustrated in figure 1. the differences between marcive and marc are as follows: 1. marcive's leader consists of three fields: length of disc space, status code, and length of record. in converting marc the following elements of the marc leader are incorporated in the marcive leader fields: length of disc space, status code, and length of record. 2. marcive does not contain the marc record directory, but rather places the tags and subfield codes in front of the actual data. 3. in the conversion from marc ii to marcive, fixed fields such as date of publication are omitted. 4. all data elements in marcive are treated as variable tags even though they contain fixed field data. 5. marcive uses the mnemonic code names for the input of data rather than the numeric marc codes. for example "mep" is used for coding a person as main entry rather than "llo." the mnemonic tag names are stored in the machine format and not the numeric marc tags. ,, ·' 186 j oumal of libra1'y automation vol. 7 i 3 september 197 4 '""d ~ .... ~ 0 i5 cj " "' .oj "' "' .oj § ~ s s " '""' p:; ql "' ql ~

most of the second indicators are not input, except for the filing indicators which are included in the marcive format. 8. marcive adds one variable tag to the marc format called "fin." it serves the function of the marc 090 local holdings tag. the fin tag must be the first variable tag in each marcive record and must contain four data elements: ( 1) accession number; ( 2) type of material code (monograph, serial, etc.); ( 3) location of material within library (reference, reserve, etc.); ( 4) local call number. even though marcive is not a pure marc format, there has been an attempt to code most of the data elements into marcive. a marcive to marc conversion is being written by one of the marcive libraries in order to merge its marcive data base with a purchased marc data base. marcive master data bases each of the m arcive users maintains a separate data base of its holdings, which is called its marcive master. this master file contains a complete bibliographic record for each title cataloged by the library, including marc cataloging and local cataloging. when a library modifies a marc record, the modified record is recorded in that library's marcive master. the various libraries' marcive masters have not been merged, although this is being considered. each library has prefaced all of its accession numbers with a unique library code just in case a merged data base is desired. marc-con data base the largest data base in the system is the marc-converted data base, marcive/bowden and miller 187 hereafter referred to as marc-con. this data base contains only pure marc data that have been converted into marcive machine format. no original cataloging or local modifications of marc are contained in the marc-con data base. marcive programs convert-this program reformats the weekly marc tapes into the marcive machine format. marc-update-this program merges the weekly converted marc tape with the marc-con disc file. an index sequential ( isam) file containing lc card number, fifty characters of the title, and the disc address of the marc reoord is generated. the isam file is in lc card number order. in 1974 the marc-con data base filled three 3330 disc packs. there are three tape back-up files: one file consisting of original marc records, one of the marc-con records, and a third with the isam file. deleted records and replaced records are annually purged from the marc-con files. a new set of back-up tapes for the disc packs is created every three months in order to facilitate regeneration of the disc packs should damage occur. marc-list-this program lists marc records in title sequence from the tape. once every six to eight weeks the list is cumulated and printed. these lists are used for searching until the annual cumulation of the nuc is received. this provides current listings of records on the marc tapes that are not easily available in the national union catalog. this listing will be eliminated in 1974, when access by title to the marc-con data base is available. marc-search-this program searches for lc numbers on the marc-con file using the isam file. a file of the matched records is produced on tape or disc as specified along with a listing of these records. this listing contains the marc-con complete bibliographic entry (figure 2). although access is currently only by lc card number, access by title algorithm ( 3, 1, 1) is expected in 197 4. replace-the purpose of this program is to modify marc-con records to fit the needs of the individual library. these modifications can be done automatically to all records or on a single record basis by the library. the automatic changes are specified on a control card and include twenty-two options such as assignment of accession number, usage of dewey class number instead of lc, and changing "u.s." in subject headings to "united states." an example of a single modification would be the changing of a series entry from t~·aced to untraced. most marcive participants use a combination of automatic and single changes. the output from the replace program may be input to all other marcive programs, such as edit, catalog card, update, etc. edit-this program verifies the format of the input. valid tags and subfields as well as correct sequence of tags are checked. multiple spaces 188 journal of library automation vol. 7/3 september 1974 library

(figure 3) . the mini-edit lists the input for each title and any error messages. the error-edit lists only the input form and the error message of those titles which do not conform to specifications. a library might use the error-edit for cataloging data from the marccon file as the proofreading has occurred after the search phase. however, for original cataloging in which all data have been input locally, the full-edit would be most beneficial. acquisitions list-this program produces listings arranged by classification in a format suitable for printing on 8~~-by-ll-inch paper. these listings include the following data elements for each title: main en190 journal of library automation vol. 7/3 september 1974 try, title, imprint, collation, call number. the items are sorted by author within classification. catalog card-this program produces catalog cards on one-up stock the ibm tn train is used and the printing is eight lines to an inch. the program has many options including number of cards produced by type of entry, and whether or not the tracings will print on the tops of the cards. the cards may be printed in filing order in the following arrays: 1. shelflist arranged by call number. 2. main entry-title-series-added entries in one alphabet arranged alphabetically by the first eight characters of the first word, excluding designated prefixes. 3. subject entries in one alphabet arranged alphabetically by the first eight characters of the first word. the alphabetizing is intended to be a prefiling aid and not to be used as the absolute filing arrangement since each library adapts the filing rules for its own collection. the cards may also be printed in set order. examples of typical catalog cards are shown as figure 4. book catalog i-this is a modification of the acquisitions list program in which the classification does not print. it is used to list faculty publications. book catalog 11-this is a modification of the catalog card program in which the cataloging information is printed with all blank lines compressed. since it is a variation of the catalog card, any type of catalog can be created by specifying the type of entry and then having it prefiled accordingly. trinity produces an author-title book catalog which is used in the interim period between the production and the filing of the catalog cards. thus, the public has a listing of new titles added to the library. book catalog iii-this program generates a book catalog arranged by classification. it is similar to book catalog ii but tracings are not printed (figure 5). indexes by added entry, title, and subject are also generated. update-this program merges the additions and deletions to the marcive master file, producing an updated master and a listing in classification sequence of the additions. the marcive master is in accession number order. duplicate accession numbers are rejected. select-this program generates bibliographies from the marcive master files (figure 6). any tag and its subfields can be searched. the output can be sorted by call number, main entry, title, or any other bibliographic element in marcive. the program can be a powerful search tool for a library. however, the program's method of retrieval is by comparing input data with each record on the file, which can be a very expensive process. there have been discussions of building isam files for various points of entry. build misam-this program builds an isam file to the marcive hf 5549 • .5 r3 f54 245701 marcive/bowden and miller 191 finkle, . robert,; b.,. 1922-... . assessing corporate

this isam file is then used by the marcive search program. this isam file is built only on demand. marcive search-this program searches for accession numbers on the marcive isam file. a disc file and a listing of the marcive records is generated. this file can be corrected by using the replace program, thus creating a corrected disc file which can be input into the various marcive programs. using the marcive system the original marcive programs used only keypunched card input. the cataloged data were coded with the marc mnemonic codes and then keypunched. the resulting decklet of cards was the input to several programs. if in the edit program an error was detected, the appropriate punched card could be corrected and the decklet resubmitted to the edit program, or that program could be bypassed and the decklet input into the catalog card program. these same decldets were saved for the monthly acquisition list. they were not stored on disc until recorded on the marcive master disc file in the update program. although this may seem awkward, it was easier for the library staff, who thus did not worry about change codes and deletes, but could work with their prime input, the keypunched cards. the uthscsa library still uses the keypunched card method of input, since its cataloging is based on the national library of medicine's cataloging. citations are manually coded with the m1arc mnemonic codes at a rate of one to three minutes per title. keypunching takes approximately five minutes per title and is much easier than typing a catalog card because placement on the catalog card is not a consideration. the keypunched data are input to the edit program and the full-edit listing is used for proofreading. correct data are input to the catalog card program, then saved for input to the monthly acquisitions list and the update programs. the other libraries in the marcive system use the marc-con portion of the marcive system. with the addition of the marc tapes it became possible to bypass the coding and keypunching steps, thus. saving both time and effort and reducing the chance of error. at trinity university library when books arrive for processing, a library clerk keypunches the lc card number for each book published after 1968. these keypunched cards are then submitted to the marc search program. the books are matched against the search listing of marc data and any cataloging changes in addition to certain automatic changes are noted on the listing. when the books on a search listing are checked and classified, the books are sent for further processing for the shelves. unmatched books are held for later input to the search program. the corrected search listing is sent to the ibm 2741 typewriter terminal operator. the operator types an input file of changes to the marc marcive/bowden and miller 195 records, such as a series entry change. trinity uses the following automatic options in the replace program: ( 1) the call number used is the lc call number without the period; ( 2) a sequential accession number is generated; ( 3) the date entered on the file is added to the record; ( 4) library location code is generated; ( 5) "u.s." and "ct. brit." in subject headings are spelled out. the change file plus the automatic options control data are transmitted via telephone line to the computer and submitted to the replace program. the replace program modifies the records on the search file and creates a file of records which can be used by any of the marcive programs to produce catalog cards, book catalogs, or updates to the library marcive master. since many automatic options have been included in the replace program, the correction required on marc search records is minimal and a great many catalog cards can be created with little or no input required from the library. books published before 1968, unless one of the marc popular titles, must be fully coded and input by the trinity university library staff. this represents about 25 percent of the books cataloged by the library, with the percentage varying from month to month depending on the cataloging priorities in the department. trinity university library is the only marcive user that inputs via an on-line terminal. this is a much more expensive though versatile method of input. all of the other marcive users who modify marc search records follow the same procedure except all input is via punched cards. · one potential marcive user is experimenting with producing catalog cards without any interim editing of the marc records other than the automatic options available through the replace program. this. method of catalog card production is quicker and less expensive and would be useful for many libraries. benefits the benefits of the marcive system must be compared to the manual system which it replaced. clerical staff time to type tracings and call numbers has been eliminated. trinity has effected major time savings by eliminating the maintenance of proof slips. uthscsa has reduced the typical three-week period during which the unit card was reproduced by a commercial firm to one week. the production of the monthly acquisitions list which formerly took days is now accomplished in a matter of minutes. production of bibliographies is also now an easy task, whereas in the manual phase it was done only by manually searching and copying the card catalog. uthscsa has also utilized the marcive system for the cataloging of local products-the videotapes produced by its television department, the citations of publications of its faculty and staff, and most recently the cataloging of computer assisted instruction programs, a project funded by 196 journal of libmry automation vol. 7/3 september 1974 the national library of medicine. the marcive system was used to produce book catalogs for each of the above. costs the costs of developing the marcive system were borne by trinity university library and the trinity university computer center. there was no outside funding for the development. no records were kept of the computer time used to test the marcive programs since all computer time was charged to a university-wide academic budget. during the various development periods of the marcive system there were never more than 1.5 full-time employees engaged in the project. table 1 is an estimate of the manpower and time spent in the various phases of the system. the library paid the salary of the librarian and the computer center paid the salary of the programmer. marcive evolved as the result of the cooperation of both departments within the university and would not have been possible if the administration had not supported the project. table 1. estimated time and manpower

.5 .25 .25 .25 .5 1.25 1.00 .25 charges to a marcive library are presently determined by the number of programs that the library uses and the method of input. a program's cost is based on cpu time, cards read, number of lines printed, and online data storage. commercial rates which reflect overhead and salaries are used. method of input can be keypunched cards, typewriter terminals, or magnetic tape. the computer costs for producing a set of catalog cards depend on the method of input, whether the marc tapes are searched, which edit listing is used, and the length and number of cards produced. an additional $0.02 per card is charged for the cost of card stock and the maintenance of the system. in 197 4 this charge will be increased to $0.03 per card to cover the rising costs of paper. uthscsa has kept records of the cost of each computer job since 1971. the average cost per card for 65,217 cards in finished form produced between april 1972 and august 1973 was $0.024 per card. considering that the average set had ten cards and a surcharge of $0.02 per card was added, the cost for producing a set of cards was $0.44. for the average 400 titles cataloged by uthscsa in each month, the marcive system charge would be .$246.00. the same input can be used to produce the monthly acmarciveibowden and miller 197 quisitions list at a cost of $0.015 per title, or $6.00 per list. the addition of a title to the marcive master disc file is an additional $0.03 per title. an average monthly bill for marcive computer services is $262.00. to this should be added the $40.00 prorated cost of the uthscsa keypunch which is also used for other projects, giving a total of $302.00, or $0.755 per title. a library assistant codes and keypunches the data as one half of the job assignment. an average of fifteen minutes per title is involved in the coding, keypunching, proofreading, and handling of data. at a salary rate of ·$4.00 per hour, this amounts to $1.00 per title. transportation costs for delivering data average $17.00 per month at $0.10 per mile. trinity university retrieves 75 percent of its cataloging data from the marc tapes via the search program. the per title cost of this retrieval varies according to the number of items searched and reflects the fact that the more records a computer processes, the less expensive the process becomes. during september 1973 a search of 723 lc numbers resulted in a $0.025 computer charge per retrieved title. a search of 10 lc numbers cost $0.05 per retrieved item. trinity edits each retrieved title to make local changes and to add an accession number. the average cost for this using the replace and edit programs is $0.12. thus batch retrieval from the marc tapes combined with the modification of these records costs from $0.145 to $0.17. the marcive system and the oclc system it is useful to compare the attributes and limitations of the marcive system with those of the ohio college library center ( oclc) system. the two were developed fully independently of one another during the same period of time. 5 oclc is an on-line system with access to the cataloging input of its member libraries in addition to the marc tapes. this access is by authortitle and title algorithms in addition to lc number. marcive is a batch system with access to the marc tapes by lc card number. even though it is a batch system, the libraries in the marcive system enjoy high priority which enables immediate usage of the computer, and jobs are executed throughout the day. the turnaround time for jobs other than search is one to two hours. because of the large size of the marccon file, search programs are executed only at night, so the turnaround could be as much as twenty-four hours. the importance of the access to the oclc member libraries' original cataloging in addition to the marc tapes has not been evaluated. oclc reports that 71 to 76 percent of new requests run against the marc file produce hits. an eventual success rate approaching 100 percent was predicted. 6 it would seem that the marc tapes would be sufficient for all but the larger or more esoteric libraries. printed copy is generated from a marcive search of the marc tapes, ;.,i ~~ i ,, 198 jou1'nal of libm1'y automation vol. 7/3 september 1974 thus allowing a library which does not accept lc cataloging unaltered to do its checking and revising off line. oclc displays the retrieved item on a crt screen. printed copy would be generated only if a special attachment at additional cost could be hooked to the terminal. if a library accepted lc data as displayed, only one retrieval would be necessary. if, however, the procedure was similar to that described by walsh college library, two retrievals would be made. in this procedure, some manual transcribing from the oclc crt screen is made in order to check the entry in the library catalog. 7 however, oclc does not presently charge for aretrieval with no other transaction. the costs for catalog cards produced by oclc and marcive are similar. kilgour has reported that oclc cost for formatting but not printing catalog cards is $0.0221 using commercial rates. a printing cost of $0.0033 was also given. 8 uthscsa reports a cost of $0.024 for the average catalog card, including formatting and printing. oclc charges a fixed price of $0.035 per catalog card. 9 marcive takes the commercial cost of producing the cards and adds an additional $0.02 per card for card stock and system maintenance, thus causing the average card to cost $0.044. in 197 4 the surcharge will increase to $0.03 per card to cover the increased cost of card stock, thus causing the average card to cost $0.054. it is in retrieval charges that a significant difference occurs between the marcive and oclc systems. it has been difficult for the authors to know the precise costs of oclc to participants as these vary according to the structure of the agreement and the location. we have chosen to compare the marcive costs to those of the iucjoclc system which has recently negotiated a contract. these costs do differ in structure from the oclc member libraries. in the agreement between oclc and the interuniversity council ( iuc) of the north texas area, the charge for service is based upon the calls made upon the oclc system for catalog ca1'd p1'oduction whe1'e the cataloging data 1'equested m·e found within the oclc data bank. such a call, referred to as a "hit," is charged at the rate of $0.875. to this must be added such items as leased line costs, terminal hardware and maintenance costs, local training and administrative costs, etc. the total of these costs is approximately ·$1.70 per hit. 10 no charge is made for retrieval from the oclc system unless catalog cards are requested, or for material input by the requesting library. if a library were to catalog 1,000 books using retrieved data from the oclc system, the charge would be $1,700 plus the cost of catalog cards and postage. if a library were to catalog an additional 200 titles not found on the oclc data bank and input these titles into oclc, the charge for the 1,200 titles would still be $1,700 plus the cost of catalog cards and postage. in the marcive system there is a charge each time the marc tapes are accessed, regardless of whether catalog cards are produced. retrieval from the marc tapes via the marcive system costs between $0.025 and marcive!bowden and miller 199 $0.05 per title, depending upon the quantity and percentage of matches in a hatched search. costs vary according to the mode of input from the $80.00 monthly rental for a keypunch machine to the $120.00 rate for an on-line typewriter terminal. using the maximum $0.05 per title retrieval cost and the ·$120.00 terminal cost and adding another $0.12 for the replace and edit programs, the cost for 1,000 titles is $290.00 plus online data costs. using the minimum $0.025 per title and $80.00 for the keypunch machine and adding the $0.12, the cost for 1,000 titles is $225~00. although all the factors which account for this charge variation are not known, the following appear to be significant. first, the costs inherent in an on-line system may be higher than in a batch procedure. second, the size of the oclc data base, which in 1972 had 181,209 member records in addition to the 229,807 marc records, may increase search time and thus costs. third, overhead costs of the oclc staff and their developmental projects in other areas may be a factor, although the substantial grant support oclc has received should have offset some of such costs. marcive presently serves five libraries within a twenty-minute driving area that are responsible for picking up their own output. marcive has minimal overhead costs. the present pricing structure of the computer center has covered its overhead costs. all new development is separately funded. mrs. miller's salary has been totally absorbed by trinity university library even though she is the marcive liaison for the computer center in addition to her responsibility as head of trinity library's cataloging department. it is probable that if marcive were to expand the number of participating libraries, additional administrative support would be required. the present pricing structure used by marcive would then be reevaluated. current developments continued development of the marcive system is in progress. one of the marcive libraries is programming a marcive to marc conversion which will allow it to merge its marcive holdings with a purchased marc data base. programming is underway to create book labels. additional access indexes to the marc files are also being programmed. some procedures which are feasible now were not feasible when the original programs were written. for example, it would be logical for the update program to generate both an updated master and an isam file, instead of the latter requiring the build misam program. the catalog card program will be rewritten for output on two-up card stock using the ala print train. a union catalog and a joint circulation system for the participating libraries are also possibilities. in january 1974 the marcive users' group was formed as a special interest group of the council of research and academic libraries. its purposes are: ( 1) to share information among users regarding problems, procedures, and needs pertaining to the marcive library system; (2) 200 journal of librm·y automation vol. 7/3 september 1974 to establish guidelines, standards, and manuals for input, output, and reporting procedures of user libraries; ( 3) to maintain a sound financial policy for the marcive system; ( 4) to explore and develop new ideas for programs, techniques, and procedures to further enhance the marcive system; ( 5) to recommend changes and/ or new programs for the marcive system; and ( 6) to assist libraries in the installation of any marcive programs. a major project of the users' group has been the writing of a detailed procedure manual for the marcive system. conclusion the marcive system is an excellent example of library cooperation in which the sharing of facilities, interest, and expertise has had great benefit for all concerned. in 1971 only trinity university and the university of texas health science center at san antonio used the marcive system. with the addition of accessibility to the marc tapes, san antonio college joined in 1972 and the university of texas at san antonio and st. mary's followed in 1973. one factor which made this cooperation possible was the formation in 1968 of a consortium of libraries in the san antonio area, the council of research and academic libraries (coral). its membership is comprised of the academic, public, and special libraries in the area. another factor has been the trinity university library and computer center staffs' enthusiasm and graciousness, which have been of great importance in fostering the desire to cooperate. too many projects fail because of lack of communication between participants. such communication can be as important a consideration as economic benefit in the decision to enter into a consortium. references 1. ruby b. miller and robert a. houze, "new horizons in computer applications at trinity university library," texas library journal

libraries: a qualitative study shea-tinn yeh and zhiping walter information technology and libraries | september 2016 27 abstract integrated library systems (ilss) support the entire business operations of an academic library from acquiring and processing library resources to making them available to user communities and preserving them for future use. as libraries’ needs evolve, there is a pressing demand for libraries to migrate from one generation of ils to the next. this complex migration process often requires significant financial and personnel investment, but its success is by no means guaranteed. we draw on enterprise resource planning and critical success factors (csfs) literature to identify the most salient csfs for ils migration success through a qualitative study with four cases. we found that careful selection process, top management involvement, vendor support, project team competence, staff user involvement, interdepartmental communication, data analysis and conversion, project management and project tracking, staff user education and training, and managing staff user emotions are the most salient csfs that determine the success of a migration project. introduction the first generation of integrated library systems (ilss) were developed specifically for library operations focused on the selection, acquisition, cataloging, and circulation of print collections. as libraries’ nonprint materials steadily grow, the print-centric ilss became less and less efficient in supporting libraries’ daily operations. recent years have seen an emergence of a new generation of ilss, commonly called library services platforms (lsps), that takes into account the management of both print and electronic collections. lsps take advantage of cloud computing and network advancements to provide economies of scale and to allow a library to better share data with other libraries. furthermore, lsps unify the entire suite of library operations to provide efficient workflow at the back end and advanced online discovery tools at the front end for the library.1 given the claimed benefits of the emerging lsp and the fact that vendors are phasing out support for their legacy ilss, we project that more libraries will be migrating to lsps as the systems mature and libraries’ needs evolve. shea-tinn yeh (sheila.yeh@du.edu) is assistant professor and library

mailto:sheila.yeh@du.edu mailto:zhiping.walter@ucdenver.edu) critical success factors for integrated library system implementation in academic libraries: a qualitative study | yeh and walter |doi:10.6017/ital.v35i2.9255 28 migrating from one generation of ils to another is a significant initiative that affects the entire library operation.2 because of its scale and complexity, the migration project is not always smooth and often fraught with problems, with some projects falling behind migration completion schedule.3, 4, 5 in addition, committing to a new system often results in significant financial and personnel costs for an academic library.6 understandably, there is considerable trepidation before, during, and after the migration process.6, 7 what contributes to a smooth migration process and a successful migration project? this is an urgent question at present and an enduring question for the future. this is because, as libraries continue to evolve, their operations and management needs are destined to outgrow functionalities of the current generation of ils. therefore migration to a new generation of ils is destined to occur periodically for a library. in this research, we study critical success factors (csfs) that contribute to a smooth migration process and a successful migration project defined as on-time and on-budget project completion and a smooth implementation process. to achieve our research goal, we anchor our theoretical foundation in the enterprise resource planning (erp) system-implementation literature. erp is “business process management software that allows an organization to use a system of integrated applications to manage the business and automate many back office functions related to technology, services and human resources.”9 since a complete ils is formed from a suite of integrated functions to manage a broad range of library processes, it is in fact an erp for libraries.10 a literature review of csfs for erp system implementation success revealed more than ninety csf factors.11, 12 the contribution of our research is in identifying, through qualitative research method, the most salient csfs that contribute to the success of a library system migration project from one generation of ils to another. results of this study can help library administrators to improve the chance of success and decrease the level of anxiety during a migration project now and in the future. the remainder of the article is organized as follows: section 2 reviews erp, ils, lsp, csfs, and information system success measurement described in the literature. section 3 describes the guided interviews that have been conducted to identify the csfs, the results, and the analysis of the results. finally, we offer conclusions and limitations as well as recommend future work. literature review erp is business-management software comprising a suite of integrated applications that an organization can use to collect, store, manage, and interpret data from many business activities, including product planning, manufacturing, service delivery, marketing and sales, and human resources. the core idea of an erp system is to integrate both the data and the process dimensions in a business so that transactions can be monitored and analyzed for planning and strategic purposes.13 modules of the system cover different functions within a company and are linked so users can see what is happening in all areas of the company. an erp system can improve a business’s back offices as well as its front-end functions, with both operational and strategic benefits.14 some of the benefits include reliability in information access, data and operations information technology and libraries | september 2016 29 redundancy, data retrieval and reporting efficiency, easy module extension, and internet commerce capability. just like an erp system for a business, a complete library management solution comprises a suite of integrated applications that manage a broad range of library processes including circulation, acquisition, cataloging, electronic resources management, and system administration. lsps, the current generation of library management systems, are designed to manage both physical and digital collections. lsps follow the service-oriented architecture (soa) and can be deployed through multitenant software as a service (saas) distribution model.15 in addition to supporting all library functions, lsps integrate with other university systems, such as student registry and finance, and provide front-end for library patrons in a cloud environment that leverages a global network of systems for discovery of a wide array of resources.16 since an lsp is essentially an enterprise system for library functions, csfs of erp implementation success could guide lsp implementation. csfs are conditions that must be met for an implementation to be successful.17 more than ninety csfs have been identified for erp implementation success.18, 19 those csfs have been classified according to various schemes, but we found the strategic versus tactical classification most relevant to the library context.20 strategic factors address the big picture involving the breakdown of goals into do-able items. tactical factors, on the other hand, are the methods to accomplish the doable items that lead to achieving the goals.21 by examining the entire list of csfs from both the strategic and the tactical perspectives, we identify top csfs for library-management-solution implementation and migration success, defined as on-time and on-budget delivery as well as smooth implementation process,22, 23 through a qualitative study. method we conducted semi-structured interviews with open-ended questions to identify the most salient csfs for implementation success. since we needed to reduce more than ninety csfs in the literature to a list of most salient csfs in the library context and to potentially identify new csfs, a qualitative-interview approach was more suitable than a quantitative-survey approach. a twostep process was used to arrive at the final list. first, we evaluated all csfs in the literature and identified a subset of csfs that might be most relevant for library-systems implementation.24 second, this csfs subset was used to develop an interview guide for semistructured interviews conducted later to further reduce this subset. open-ended questions were also used during the interviews to elicit additional csfs. an institutional review board (irb) application was submitted and approved. the result of this two-step process is a list of ten csfs discussed in the results section, with nine csfs coming from our initial list and one csf emerging from the interviews. the criterion for recruiting study libraries is that the library has implemented a new lsp within the last three years. this is because the lsp is the current generation of ils, and it is only within the last few years that various lsp vendors began to promote and implement the lsps. a critical success factors for integrated library system implementation in academic libraries: a qualitative study | yeh and walter |doi:10.6017/ital.v35i2.9255 30 recruitment email was sent to libraries listed as adopters on various vendors’ press release sites. participating recipients referred the interview request to appropriate migration team members whom we later contacted to schedule interviews. this resulted in up to five people from each participating library being interviewed in person or via skype. their positions are listed in table 1. interviews were recorded, transcribed, and cleaned. emails to the same interviewees were used for follow-up questions as needed. after interviews with each library, qualitative data analysis was performed to identify csfs that emerged from the interviews. interviews continued until no new csfs emerged in the last interview. in total, staff from four libraries were interviewed between october 2014 and march 2015 about their implementation process and experience from staff user perspective. the design and implementation of discovery public interface experience was not part of this inquiry. table 1 summarizes characteristics of the four libraries. case numbers instead of university names are used to protect identities of

vendor support, project team competence, staff user involvement, interdepartmental communication, data analysis and conversion, project management and project tracking, staff user education and training, managing staff user emotions. we discuss each csf next. information technology and libraries | september 2016 31 careful selection process most ilss are commercial, off-the-shelf software systems that can vary dramatically in functionality from system to system.25 for example, some packages are more suitable for large institutions while others are more suitable for smaller ones. to mitigate risks in productivity or transaction loss and to minimize system and implementation costs, a library needs to determine the best “fitness-of-use” system. such a determination is the outcome of a careful selection process. although there is no commonly accepted technique, method, or tool for this process, all selection processes share common key steps suggested in the literature.26 they are the following as applied to library-systems selection: define stakeholder requirements, search for products, create a short list of most promising candidates based on a set of “must-have” requirements, evaluate the candidates on the short list, and analyze the evaluation data to make a selection. in addition, if the server option was chosen instead of the cloud option, selected hardware needs to satisfy system requirements for the final configuration. careful selection process emerged as a csf that affected implementation outcome for all four libraries. all cases were migrating to an lsp system. some systems can be offered as locally installed systems, which require appropriate in-house and hardware capabilities. case 1 did not consider its it capability when deciding on a turnkey system. as a result, the library experienced difficulties in setting up the infrastructure in-house during the implementation. each of the other three cases considered the candidate system’s compatibility with the legacy system, the match between library needs and system functionalities, system maturity, migration costs, data storage needs, and vendor support before and during the implementation as well as continued vendor support throughout the life of the new system. even though each of the three libraries arrived at its system choice differently, on reflection, interviewees expressed relief and satisfaction in their decisions to choose their respective systems. “we were in the position where our servers were out of date and warranty, needed to be replaced. the servers were too small. we had sizing issues and we couldn’t update to the most recent version of aleph . . . alma being a cloud based solution will eliminate our need to be ‘in the server business.’” (case 2). “we went through a very extensive formal process to select this system.” (case 3) top management involvement successful implementation requires strong leadership by executives who understand, support, and champion the project.27 when this involvement is trickled down through organizational hierarchy, it leads to an organizational commitment, which is required for implementation success for complex projects.28, 29 since library-system implementation is a complex project that (if done correctly) will transform the entire library and reposition it for better efficiency, strong leadership is critical as well. critical success factors for integrated library system implementation in academic libraries: a qualitative study | yeh and walter |doi:10.6017/ital.v35i2.9255 32 in all four cases, top management were involved in the final decisions of their respective system choices. in cases 1 and 2, top management also took charge in securing funding for the migration projects. interviewees stressed that top management support was very important in their respective project implementations. “the top level management took the recommendations from the systems librarians at the time, with the blessing of the council determined whether they want to proceed with the product alma, and had funding conversations with the financial people.” (case 2) “we have faculty library committee, faculty governance oversight. we showed them webinars of the products we considered before we signed them, so we have faculty representation on board. we held open forum and were inclusive in our invitations.” (case 4) vendor support with a new technology, it is critical to acquire external technical expertise, often from the vendor, to facilitate successful implementation.30 effective vendor support includes adequate and highquality technical support during and after implementation, sufficient training provided for both the project team and staff users, and positive relationships between all parties in the project.31 additionally, there should be adequate knowledge transfer between the vendor consultants and the clients, which can be achieved by defining roles, achieving shared understanding, and enhancing relationships through competent communication.32, 33 in the case of library-system implementations, vendor support is particularly important because of the complexity of each new generation of the system and the library personnel’s knowledge gap in understanding the nuts and bolts of the new system. effective vendor support was identified in each case as a critical success factor determining the implementation outcome even though the form of vendor support varied from case to case. in case 1, the vendor sent different consultants with various expertise as project managers on the basis of the project phase. in case 2, the vendor sent one consultant who served as the main project manager. in case 3, the vendor provided a project manager and a team of technicians. in case 4, consultants were shared across multiple consortium libraries that were implementing the system at the same time. no matter how vendor support was provided, it was essential for implementation success as indicated by interviewees. “the vendor has been very supportive and provides a group of experts throughout the process, some are knowledgeable in server business while others are skilled project managers.” (case 1) project team competence since library-system migration affects all functional areas of a library, members of the implementation team need to be cross-functional. furthermore, members with both business information technology and libraries | september 2016 33 knowledge and technology knowhow are especially crucial for implementation success.34 competence of vendor consultants assigned to the project also influences implementation success, as discussed earlier. additionally, it is important to have an in-house project leader who champions the project and who has the essential skills and authority to set goals that legitimize change.35 having a competent project team was essential for implementation success for each of our cases. in each case, the vendor provided the project manager and the library provided a co-manager who was a champion figure. other team members came from various functional areas such as acquisition, circulation, cataloging, electronic resources management, and system administration. for example, in case 1, the technology librarian participated as a co-project manager. the projectmanagement team comprised module experts within the library and from functional areas. in addition, the university’s technology services department lent technical support during early stages of implementation when servers need to be set up. the interviewees all stressed the importance of project-team competence. “without the infrastructure knowledge from the university’s technology team and their time and full support to negotiate with the vendor, the migration project would not have been possible.” (case 1) “the university’s it made sure that we are in compliance with campus policies and expectations for securities.” (case 2) staff user involvement it is important that the project team involve staff users early on, otherwise the implementation process may be bumpy. when end users are involved in decisions relating to system selection and implementation, they are more invested in and concerned with the success of the system, which in turn leads to greater system use and user satisfaction.36, 37 as such, it is one of the most cited critical success factors in erp implementation.38 because personal relevance to the system is just as important for library-system implementation, effective staff user involvement with implementation is positively related to implementation success. staff user involvement has emerged as a main success factor in all our cases and contributed to the implementation project outcome. in case 1, staff users were not consulted as to whether an lsp was necessary for the library, although they were informed of the reasons for implementation. additionally, staff users were not involved when the project timetable was negotiated. this lack of early staff user involvement led to considerable stress down the road, which made the implementation process bumpy. the other three cases involved staff users early on; as a result, staff users experienced much less stress and frustration down the road. specifically, in case 2, the staff users were educated about the need for migration through staff meetings, town hall meetings, supervisory meetings, council meetings, and forums. many product-demo sessions were conducted for the staff so they would have the knowledge to participate before the final decision critical success factors for integrated library system implementation in academic libraries: a qualitative study | yeh and walter |doi:10.6017/ital.v35i2.9255 34 was made. there were daily internal newsletters conveying implementation news throughout implementation months. in case 3, the entire library was involved with the selection of a new system. while the key staff (such as circulation manager, acquisition manager, and reference manager) had more input than others, everyone offered input about the project. as such, the buyin with the new system was strong from all stakeholders. in case 4, staff users were involved early on through open forums and webinars. the following quotes are examples of interviewee sentiment concerning staff user involvement: “everybody is involved in choosing the system; partially because evergreen had been so problematic. we wanted to make sure that everyone is on board.” (case 3) “migration is the most time consuming aspect of the library staff work during the time of the project, without their buy-ins, it is difficult to have a successful project.” (case 4) interdepartmental communication the importance of effective communications across functional and departmental boundaries is well known in information-systems-implementation literature.39 with consultants coming from the vendor, project team members coming from different functional areas, and staff users with different perceptions and understandings of the implementation project, the importance of effective communications between all involved cannot be overstated. communications should start early, be consistent and continuous throughout various stages of the implementation process, and include a system overview, rationale for implementation, briefings for process changes, and contact-points establishment.40 expectations and goals should be communicated to all stakeholders and to all levels of the organization.41 effectiveness of interdepartmental communication affected the implementation outcome in all our cases. in case 1, the library’s project manager was designated to communicate with the vendor when issues arose, such as hardware and software configurations, system backup and use, and task assignments. the formal project plan was established using the web-based basecamp so that team members in different roles with different responsibilities could communicate and work together online. regular meetings were held and emails were exchanged between project team members. however, there is a lack of effective interdepartmental communication with staff who were not on the project team. this resulted in the absence of necessary system testing that would have detected some data-integrity issues. such issues later caused the system to be offline for days, which brought much frustration and stress to everyone. in the other three cases, all actors were well informed through news releases, meetings, presentations, and webinars. concerns were communicated to the project team and addressed timely. as a result, the level of frustration was very low for those three cases. data analysis and conversion a fundamental requirement for the effectiveness of an erp system is the accuracy of its data,42 and the same is true for a library system. data types in a legacy ils are often of an outdated format and information technology and libraries | september 2016 35 can differ from formats supported by a new library system. conversion from one format to another can be an overwhelming process, especially when there is no existing expertise in the library. since migrating legacy data to the new system is essential, effective data analysis for conversion is a critical success factor for implementation success. the smoothness of each of the four implementation cases was related to the project team’s data analysis and conversion efforts. in case 1, the library did not spend any effort to analyze, convert, or clean the data. as a result, the system experienced data-integrity issues after it went live. the other three libraries either devoted time to clean and convert the data or had a third party do the data cleaning. as a result, no system issues arose from data-integrity problems. interviewees from case 2 told us, “we elected to freeze the data 30 days sooner in terms of bibliographic data, so that we can do an authority control project with a third party vendor.” project management and project tracking according to erp implementation literature, effective project-management practices are critical for implementation success. such practices include defining clear objectives, establishing a formal implementation plan, designing a realistic work plan, and establishing resource requirements.43 the formal implementation plan needs to identify modules to be implemented, tasks to be undertaken, and all technical and nontechnical issues to be considered.44 project progress must be carefully monitored through meetings and reports.45, 46 effective project management and tracking has affected implementation outcome in all our cases. a popular project management and tracking software is basecamp, a web-based project management and collaboration tool initially released in 2004.47 it offers discussion boards, to-do lists, file sharing, milestone management, event tracking, and messaging system that help project teams stay organized and connected despite their different locations. all cases used basecamp for project management and tracking, which contributed to on-time and on-budget project completion for all cases. staff user education and training a new system often frustrates users who do not receive adequate training in its functionalities and use.48 when feeling frustrated and stressed, users may avoid using the system. proper and adequate training will sooth users and eliminate their reluctance to use the new system, which in turn helps realize productivity gains.49, 50 training processes should consider factors such as training curriculum, user commitment, trainers’ personnel skills and competence, as well as training schedule, budget, evaluation, and methods.51 effective staff user training has emerged as a critical success factor from all our cases. in case 1, staff users had access to a vendor-supplied preview portal, which simulated system functionalities. staff users were so familiar with the new system by the time the system went live that they were eager to engage with it. in cases 2, 3 and 4, staff users were trained through demo products, online video trainings, q&a, and on-site training sessions conducted by the vendor. critical success factors for integrated library system implementation in academic libraries: a qualitative study | yeh and walter |doi:10.6017/ital.v35i2.9255 36 these training materials and sessions served to ease staff user’s feeling of uncertainty and anxiety, as the following quotes show: “the online training videos were provided to all staff in the library and followed up with q&a sessions which members of the committee will host in their respective areas. . . . then ex libris did a week long onsite training workshop serve for the final deep configuration issues. . . . we know that there are staff users who want to be ahead of the game, yet there are always people who don’t want to learn until the day before they go live.” (case 2) “we have a training package with several onsite visits, each one is for a few days. the trainer focused on one aspect of the system. it was more than watching the videos online. because of the small staff here, almost everyone attended at least one training.” (case 3) “the trainers varied with their expertise, we developed fondness for some more than others. the training is functional in nature. the vendor’s priority was about trainer availability and to keep the project on time. we became familiar with trainers’ expertise; we were able to request the right trainer with the job.” (case 4) managing staff user emotions although education and training eases user anxiety, it does not completely eliminate it. emotions felt by users early in the implementation of a new system have important effects on the use of the system later on.52 how to manage staff user anxiety and negative emotions when they appear has emerged as a critical success factor in all our cases, as shown in the following quotes: “there were so many things going on in the library during the migration go-live week. the unknown of the migration success made staff users uncomfortable. should the migration date be decided in consideration of other initiatives, the frustration experienced would have been a lot less and might not have been ignored during the going-live week.” (case 1) “the frustration was just change; it was the fact that we have to learn something new. . . . primarily the frustration was handled by the lead.” (case 2) “there was a challenge, especially early on, in getting people to engage with the manuals and the literature in documentation. it is as if everyone is being asked to learn a new language. . . . the key relationship between the onsite coordinator and the project manager on the vendor side is important. when those two exchange information and handle frustration diplomatically, this bridge between the two organizations can smooth over a lot of rough feathers on either or both sides.” (case 4) information technology and libraries | september 2016 37 this final csf did not come directly from the ninety-plus csfs that we started with, although it aligned closely with “change management” category.53 this csf emerged mostly from the interview process. summary of results the results of the case studies for each critical factor are summarized in table 2. implementation project outcome is summarized in

undertaking that affects every aspect of a library’s operations as well as every staff user’s workflow process. as such, it is imperative for critical success factors for integrated library system implementation in academic libraries: a qualitative study | yeh and walter |doi:10.6017/ital.v35i2.9255 38 library administrators to understand what factors contribute to a successful implementation. our qualitative study shows that there are two categories of csfs: strategic and tactical. from the strategic perspective, top management involvement, vendor support, staff user involvement, interdepartmental communication, and staff user emotion management are critical. from the tactical perspective, project team competence, project management and project tracking, data analysis and conversion, and staff user education and training to break down the technical barrier greatly affect implementation outcome. in addition, selection of the final system from a variety of choices and options requires a careful consideration of both strategic and tactical issues. each factor identified is important in its own right during the implementation process. combined, they complement each other to guide an implementation to success. among the list of csfs identified, the role of staff user emotion management was not identified during the theoretical phase of the study; it only emerged as an important csf during interviews. top management involvement, vendor support, project team competence, project management and tracking, and staff user education and training are csfs that were somewhat intuitive, and they were implemented by all cases. however, a library may select an end system without careful considerations. it may also be unaware of the importance of involving users early on, the importance of opening clear lines of interdepartmental communications, or the importance of performing data analysis and conversion before the implementation. staff user emotion management, especially, is at the risk of being an afterthought of an implementation. by identifying the most salient csfs, this study offers practical contributions to academic library leaders and administrators in understanding how critical success factors play a role in ensuring a smooth and successful ils implementation. although csfs have been extensively studied in the discipline of information-systems management, this is the first study to apply csfs in the library context. since library management has its unique challenges compared to businesses, identifying csfs for library-system-implementation success is important not only for the current migration to lsps but also for future migrations to future generations of ilss as the needs of libraries continue to evolve. as with any empirical research, there are limitations to this study. the number of academic libraries interviewed is small despite no new information being discovered after the fourth interview. the vendors represented in this study are only two of the many in the market providing lsps to libraries. with these aforementioned limitations, the results of this study may not be generalizable to libraries implementing an lsp with vendors other than innovative interfaces and ex libris. additionally, the results may not be generalizable to nonacademic libraries. this research can be extended to validate the proposed csfs quantitatively by performing a survey research in academic libraries. studying interactions between identified factors will offer an even greater contribution. this research can be experimented in other types of libraries to generalize inferences. in addition, case libraries 3 and 4 both expressed that lsp changes the public interface that is used by external users, and they wished to have more opportunities for outreach prior to the implementation. although the design and implementation of the public interface was not considered within the scope of this research, this comment is insightful because information technology and libraries | september 2016 39 it may imply that future studies should consider a project champion to be a critical success factor. the project champion must have people-related skills and position to introduce changes in achieving buy-in from staff users.54, 55 references 1. richard m. jost, selecting and implementing an integrated

a partnership for creating successful partnerships | grant 5 ex libris column carl grant carl grant is [tk] ex libris column carl grant a partnership for creating successful partnerships carl grant w hen marc asked me to write this column i eagerly accepted because i feel strongly about libraries leveraging their role to their greater advantage in the rapidly changing information landscape. i see sponsorships and partnerships as an important tool for doing that. however, as noted in marc’s column in this issue, we’d been having a discussion about the continuing involvement of ex libris in the lita/ex libris student writing award. like many of you, we at ex libris are trying to keep our costs low in this challenging economic environment so that we can in turn keep your costs low. thus we are closely evaluating all expenditures to ensure their cost is justified by the value they return to our organization. i won’t repeat the discussion already outlined by marc above, but will just note with great pleasure his willingness to not only listen to my concerns, but to try and address them. his invitation to write this column was part of that response, a chance for me to share my thoughts and concerns with you about sponsorships and partnerships and where they need to go in the future. to do that, i’d like to expand on some of the concepts marc and i were discussing and talk about how to make sponsorships and partnerships successful. i want to look at what successful ones consist of as well as what types are needed in our profession tomorrow. n the elements of successful sponsorships and partnerships for a sponsorship or partnership to be successful in today’s environment, it should offer at least the following components: 1. clear and shared goals. agreeing what is to be achieved via the sponsorship or partnership is essential. furthermore, it should be readily apparent that the goals are achievable. this will happen through joint planning and execution of an agreedupon project plan that results in that achievement. it is up to each partner to ensure that they have the resources to execute that project plan on schedule and on budget. as there will always be unplanned events and issues, there must also be ongoing, open communications throughout the life of the sponsorship or partnership. this way, surprises are avoided and issues can be dealt with before they become problems. 2. risks and rewards must be real and shared. members of a sponsorship or partnership should share risks and rewards in proportion to the role they hold. furthermore, the rewards must be seen to be real rewards to all the members. step into the other members’ shoes and look at what you’re offering. does it clearly bring value to the other organizations in the arrangement? if so, how? if not, what can be done to address that disparity? sponsorships and partnerships should not take advantage of any one sponsor or partner by allocating risks or rewards disproportionately to their contributions. rewards realized by members of the sponsorship or partnership should be proportionally shared by all the members. 3. defined time. a sponsorship or partnership is for a defined amount of time and should not be assumed to be ongoing. regular reviews of how well the sponsorship or partnership is working for the partners must be conducted and decisions made on the basis of those results. it might be that the landscape is changing and the benefits are no longer as meaningful, or there are alternatives now available that provide better benefits for on of the members. maintaining a sponsorship or partnership past its useful life will only result in the disintegration of the overall relationship. 4. write it down. organizations merge, are acquired and sold, people change jobs, and people change responsibilities. any sponsorship or partnership should have a written agreement outlining the elements above. once finalized, it should be signed by an appropriate person representing each member organization. that way, when things do change, there is a reference point and the arrangement is more likely to survive any of these precipitous events. n the sponsorships and partnerships needed for tomorrow successful sponsorships and partnerships are a necessary part our landscape today. the world of information and knowledge has become too large, exists in too many silos, and is far too complex. “competition, collaboration, and cooperation” defines the only path possible for navigating the landscape successfully. as the president of a company in the library automation marketplace, i continue to seek out opportunities that uniquely position our company to effectively maintain success in the marketplace and to provide value for our customers and thus our company. i believe libraries need to seek the same opportunities for their organizations. carl grant (carl.grant@exlibrisgroup.com) is president of ex libris north america, des plaines, illinois. continued on page 7 editorial board thoughts | shores 7 looking ahead, it seems clear that the pace of change in today’s environment will only continue to accelerate; thus the need for us to quickly form and dissolve key sponsorships and partnerships that will result in the successful fostering and implementation of new ideas, the currency of a vibrant profession. the next challenge is to realize that many of the key sponsorship and partnerships that need to be formed are not just with traditional organizations in this profession. tomorrow’s sponsorships and partnership will be with those organizations that will benefit from the expertise of libraries and their suppliers while in return helping to develop or provide the new funding opportunities and means and places for disseminating access to their expertise and resources. likely organizations would be those in the fields of education, publishing, content creation and management, and social and community webbased software. to summarize, we at ex libris believe in sponsorships and partnerships. we believe they’re important and should be used in advancing our profession and organizations. from long experience we also have learned there are right ways and wrong ways to implement these tools, and i’ve shared thoughts on how to make them work for all the parties involved. again, i thank marc for his receptiveness to this discussion and my even deeper appreciation for trying to address the issues. it’s serves as an excellent example of what i discussed above. people forget, but paper, the scroll, the codex, and later the book were all major technological leaps, not to mention the printing press and moveable type. . . . there is so much potential for using technology to equalize access to information, regardless of how much money you have, what language you speak, or where you live. big ideas, enthusiasm, and hope for the profession, in addition to practical technology-focused information await the reader. enjoy the issue, and congratulations to the winner and all the finalists! note 1. all quotations are taken with permission from private e-mail correspondence. a

way utilizing technology to support and extend access to students and job seekers during the pandemic daniel berra information technology and libraries | march 2021 https://doi.org/10.6017/ital.v40i1.13261 daniel berra (danielb@pfulgervilletx.gov) is assistant director, pflugerville (texas) public library. © 2021. “public libraries leading the way” is a regular column spotlighting technology in public libraries. the ongoing pandemic necessitated a reimaging of public library services and resources. out of this challenge rose opportunities to better serve the needs of our communities during the pandemic and beyond. when our library first closed our doors to the public last march, we began discussions on how the needs of our community have changed. we identified two key groups for whom the pandemic had forced an uncomfortable shift: students suddenly thrust into virtual learning and adults who had lost their jobs. while we continue to serve all members of our community in a variety of ways, we looked to increase support for these specific groups utilizing available technology. like many public libraries, the pflugerville public library quickly shifted our service model to include virtual programs, curbside pickup, library cards issued remotely and a focus on electronic resources. our community is rapidly growing and diverse. many of our nearly 70,000 residents are frequent users of library services, attend our wide array of programs, hold meetings, study or work inside the building and enjoy both the physical and virtual library collection. the pandemic shift required our talented staff to find ways to provide a similar level of service to a community who heavily utilizes the library. for both students and job seekers, we took steps to alleviate some of the difficulties the building’s closure caused by utilizing existing technology. we worked with the city’s it department to extend the library’s wi-fi to cover the entire parking lot, allowing for 24-hour access. we also utilized our existing print from your own device system to allow library users to submit print jobs and then pick them up through our curbside service. we added additional wi-fi hotspots available for checkout to ensure access at home for those lacking internet. since these services were already offered to some degree, the expansion of access was relatively easy to implement. for students we drew upon our existing relationship with the pflugerville independent school district (pfisd) to provide support and extend access. we expanded the offering of our special digit cards, which allow students to sign up for an account giving them access to all of our electronic resources and wi-fi hotspots. the school district’s librarians handle the signups and then submit the forms so we can set up the accounts then contact students by email or phone. we further extended access to ebooks by working with the district and our vendor overdrive, to provide a direct way for students to browse and check out through the district’s own ebook app. this allows students to seamlessly see both of our collections, significantly increasing their reading options and removing barriers to access. on the support front, we utilized a portion of the city’s cares act funds directed toward the library to launch a live, virtual tutoring service called brainfuse helpnow. students of all ages have anonymous access to tutors from home seven days a week, as well as additional homework mailto:danielb@pfulgervilletx.gov information technology and libraries march 2021 utilizing technology to support and extend access | berra 2 support resources. this piece meshes nicely with some of our virtual programming for teens, like our sat and act practice tests and other testand career-preparation e-resources. recognizing the pandemic’s impact on the economy, and how this directly affects our community, we worked to prioritize support for the unemployed and under-employed. we added a resume review/job-search coaching service led by two of our circulation staff members. we utilized another portion of our cares act funds to offer career online high school, providing adults with access to an online program to obtain their high school diploma. we also began lending laptops for home use to ensure access to necessary technology. some of our support was already in place before the pandemic began, and we made a significant marketing push to highlight these e-resources. for instance, we partner with the pflugerville community development corporation to provide the online training resource lynda.com (soon to be linkedin learning). we saw a large increase in usage particularly in the first few months of the pandemic as community members looked to add employable skills to their toolboxes. we also created a page on our website with all of our job search assistance resources and services highlighted in one place. while the main emphasis of these efforts utilizes technology, serving the needs of the entire community also requires supporting those who are generally less connected. we have to balance our digital expectations with something more tangible, recognizing many library users still utilize the library in a more traditional way. for students, our senior youth services librarian partnered with pfisd for a book give away in conjunction with the district’s food distribution program to get books in the hands of children for the summer. we also began distributing “care kits” through our curbside service that include personal grooming products and cold weather gear for anyone in need. while 2020 featured the addition of many new services or significant expansion of existing ones, we are focused in 2021 on increasing our marketing efforts for these offerings. relying too heavily on digital forms of communication can limit the impact of our services. for instance, if we want to let people who do not have access to the internet at home know we have wi-fi hotspots and laptops available for checkout, then spreading the word through our standard methods of social media, website, and email will prove ineffective. with the building currently closed to the public, we face an additional barrier to communication. to help alleviate some of this, we have created a job search assistance flyer that we are distributing at places like local food pantries. we plan to expand on similar methods of marketing throughout the year. while positive feedback is often hidden from libraries since we prioritize patron privacy and anonymity, we have received a few specific stories that highlight our impact. our firs t scholarship recipient for career online high school shared how the opportunity to obtain her high school diploma will open up new professional avenues and erase the stigma of having not completed high school. another community member who took advantage of our job search coaching to prepare for an interview expressed gratitude to the library staff who helped increase his employment chances. we also see resumes and homework assignments printed through our virtual printing service, hear from parents with children utilizing hotspots for virtual schooling, see cars in the parking lot using the extended wi-fi and track statistics showing a large increase in the usage of our electronic resources. https://library.pflugervilletx.gov/services/assistance-for-job-seekers information technology and libraries march 2021 utilizing technology to support and extend access | berra 3 the ongoing pandemic necessitated a re-imagining of library services. the needs of our community changed and we set out to find ways to provide assistance to those who need it the most utilizing technology, while remaining mindful of those who are not as comfortable in the digital age. the combination of utilizing technology to address the current needs and expanding access to this technology, has allowed us to better serve the community. we are in the process now of evaluating all of our changes to determine which ones will continue even after the pandemic ends. we already know that we will keep our methods of extending access like the expanded wi-fi availability, laptops for checkout, digit cards for students and the seamless connection to our ebook collection for pfisd. in the area of support, we will continue to offer career online high school, brainfuse helpnow for virtual tutoring, and our resume review/job search coaching service. public libraries are well positioned to innovate and adjust to changes in society. it is one of the things we do extremely well, out of necessity, but also out of a deep desire to serve our communities. all of the shifts the pflugerville public library made related to supporting students and job seekers drew upon existing technology and available resources. what changed was the areas on which we chose to focus our efforts. by prioritizing support and access while pinpointing the needs of the moment, we found ways to better serve our community within the context of everything else we provide. while the jury is still out on how successful some of these initiatives will prove, we already know that many of these changes will continue long after the pandemic ends. 6 information technology and libraries | march 2009 paul t. jaeger and zheng yan one law with two outcomes: comparing the implementation of cipa in public libraries and schools though the children’s internet protection act (cipa) established requirements for both public libraries and public schools to adopt filters on all of their computers when they receive certain federal funding, it has not attracted a great amount of research into the effects on libraries and schools and the users of these social institutions. this paper explores the implications of cipa in terms of its effects on public libraries and public schools, individually and in tandem. drawing from both library and education research, the paper examines the legal background and basis of cipa, the current state of internet access and levels of filtering in public libraries and public schools, the perceived value of cipa, the perceived consequences of cipa, the differences in levels of implementation of cipa in public libraries and public schools, and the reasons for those dramatic differences. after an analysis of these issues within the greater policy context, the paper suggests research questions to help provide more data about the challenges and questions revealed in this analysis. t he children’s internet protection act (cipa) established requirements for both public libraries and public schools to—as a condition for receiving certain federal funds—adopt filters on all of their computers to protect children from online content that was deemed potentially harmful.1 passed in 2000, cipa was initially implemented by public schools after its passage, but it was not widely implemented in public libraries until the 2003 supreme court decision (united states v. american library association) upholding the law’s constitutionality.2 now that cipa has been extensively implemented for five years in libraries and eight years in schools, it has had time to have significant effects on access to online information and services. while the goal of filtering requirements is to protect children from potentially inappropriate content, filtering also creates major educational and social implications because filters also limit access to other kinds of information and create different perceptions about schools and libraries as social institutions. curiously, cipa and its requirements have not attracted a great amount of research into the effects on schools, libraries, and the users of these social institutions. much of the literature about cipa has focused on practical issues—either recommendations on implementing filters or stories of practical experiences with filtering. while those types of writing are valuable to practitioners who must deal with the consequences of filtering, there are major educational and societal issues raised by filtering that merit much greater exploration. while relatively small bodies of research have been generated about cipa’s effects in public libraries and public schools,3 thus far these two strands of research have remained separate. but it is the contention of this paper that these two strands of research, when viewed together, have much more value for creating a broader understanding of the educational and societal implications. it would be impossible to see the real consequences of cipa without the development of an integrative picture of its effects on both public schools and public libraries. in this paper, the implications of cipa will be explored in terms of effects on public libraries and public schools, individually and in tandem. public libraries and public schools are generally considered separate but related public sphere entities because both serve core educational and information-provision functions in society. furthermore, the fact that public schools also contain school library media centers highlights some very interesting points of intersection between public libraries and school libraries in terms of the consequences of cipa: while cipa requires filtering of computers throughout public libraries and public schools, the presence of school library media centers makes the connection between libraries and schools stronger, as do the teaching roles of public libraries (e.g., training classes, workshops, and evening classes). n the legal road to cipa history under cipa, public libraries and public schools receiving certain kinds of federal funds are required to use filtering programs to protect children under the age of seventeen from harmful visual depictions on the internet and to provide public notices and hearings to increase public awareness of internet safety. senator john mccain (r-az) sponsored cipa, and it was signed into law by president bill clinton on december 21, 2000. cipa requires that filters at public libraries and public schools block three specific types of content: (1) obscene material (that paul t. jaeger (pjaeger@umd.edu) is assistant professor at the college of information studies and director of the center for information policy and electronic government of the university of maryland in college park. zheng yan (zyan@uamail.albany .edu) is associate professor at the department of educational and counseling psychology in the school of education of the state university of new york at albany. one law with two outcomes | jaeger and yan 7 which appeals to prurient interests only and is “offensive to community standards”); (2) child pornography (depictions of sexual conduct and or lewd exhibitionism involving minors); and (3) material that is harmful to minors (depictions of nudity and sexual activity that lack artistic, literary, or scientific value). cipa focused on “the recipients of internet transmission,” rather than the senders, in an attempt to avoid the constitutional issues that undermined the previous attempts to regulate internet content.4 using congressional authority under the spending clause of article i, section 8 of the u.s. constitution, cipa ties the direct or indirect receipt of certain types of federal funds to the installation of filters on library and school computers. therefore each public library and school that receives the applicable types of federal funding must implement filters on all computers in the library and school buildings, including computers that are exclusively for staff use. libraries and schools had to address these issues very quickly because the federal communications commission (fcc) mandated certification of compliance with cipa by funding year 2004, which began in summer 2004.5 cipa requires that filters on computers block three specific types of content, and each of the three categories of materials has a specific legal meaning. the first type—obscene materials—is statutorily defined as depicting sexual conduct that appeals only to prurient interests, is offensive to community standards, and lacks serious literary, artistic, political, or scientific value.6 historically, obscene speech has been viewed as being bereft of any meaningful ideas or educational, social, or professional value to society.7 statutes regulating speech as obscene have to do so very carefully and specifically, and speech can only be labeled obscene if the entire work is without merit.8 if speech has any educational, social, or professional importance, even for embodying controversial or unorthodox ideas, it is supposed to receive first amendment protection.9 the second type of content—child pornography—is statutorily defined as depicting any form of sexual conduct or lewd exhibitionism involving minors.10 both of these types of speech have a long history of being regulated and being considered as having no constitutional protections in the united states. the third type of content that must be filtered— material that is harmful to minors—encompasses a range of otherwise protected forms of speech. cipa defines “harmful to minors” as including any depiction of nudity, sexual activity, or simulated sexual activity that has no serious literary, artistic, political, or scientific value to minors.11 the material that falls into this third category is constitutionally protected speech that encompasses any depiction of nudity, sexual activity, or simulated sexual activity that has serious literary, artistic, political, or scientific value to adults. along with possibly including a range of materials related to literature, art, science, and policy, this third category may involve materials on issues vital to personal well-being such as safe sexual practices, sexual identity issues, and even general health care issues such as breast cancer. in addition to the filtering requirements, section 1731 also prescribes an internet awareness strategy that public libraries and schools must adopt to address five major internet safety issues related to minors. it requires libraries and schools to provide reasonable public notice and to hold at least one public hearing or meeting to address these internet safety issues. requirements for schools and libraries cipa includes sections specifying two major strategies for protecting children online (mainly in sections 1711, 1712, 1721, and 1732) as well as sections describing various definitions and procedural issues for implementing the strategies (mainly in sections 1701, 1703, 1731, 1732, 1733, and 1741). section 1711 specifies the primary internet protection strategy—filtering—in public schools. specifically, it amends the elementary and secondary education act of 1965 by limiting funding availability for schools under section 254 of the communication act of 1934. through a compliance certification process within a school under supervision by the local educational agency, it requires schools to include the operation of a technology protection measure that protects students against access to visual depictions that are obscene, are child pornography, or are harmful to minors under the age of seventeen. likewise, section 1712 specifies the same filtering strategy in public libraries. specifically, it amends section 224 of the museum and library service act of 1996/2003 by limiting funding availability for libraries under section 254 of the communication act of 1934. through a compliance certification process within a library under supervision by the institute of museum and library services (imls), it requires libraries to include the operation of a technology protection measure that protects students against access to visual depictions that are obscene, child pornography, or harmful to minors under the age of seventeen. section 1721 is a requirement for both libraries and schools to enforce the internet safety policy with the internet safety policy strategy and the filtering technology strategy as a condition of universal service discounts. specifically, it amends section 254 of the communication act of 1934 and requests both schools and libraries to monitor the online activities of minors, operate a technical protection measure, provide reasonable public notice, and hold at least one public hearing or meeting to address the internet safety policy. this is through the 8 information technology and libraries | march 2009 certification process regulated by the fcc. section 1732, titled the neighborhood children’s internet protection act (ncipa), amends section 254 of the communication act of 1934 and requires schools and libraries to adopt and implement an internet safety policy. it specifies five types of internet safety issues: (1) access by minors to inappropriate matter on the internet; (2) safety and security of minors when using e-mail, chat rooms, and other online communications; (3) unauthorized access; (4) unauthorized disclosure, use, and dissemination of personal information; and (5) measures to restrict access to harmful online materials. from the above summary, it is clear that (1) the two protection strategies of cipa (the internet filtering strategy and safety policy strategy) were equally enforced in both public schools and public libraries because they are two of the most important social institutions for children’s internet safety; (2) the nature of the implementation mechanism is exactly the same, using the same federal funding mechanisms as the sole financial incentive (limiting funding availability for schools and libraries under section 254 of the communication act of 1934) through a compliance certification process to enforce the implementation of cipa; and (3) the actual implementation procedure differs in libraries and schools, with schools to be certified under the supervision of local educational agencies (such as school districts and state departments of education) and with libraries to be certified within a library under the supervision of the imls. economics of cipa the universal service program (commonly known as e–rate) was established by the telecommunications act of 1996 to provide discounts, ranging from 20 to 90 percent, to libraries and schools for telecommunications services, internet services, internal systems, and equipment.12 the program has been very successful, providing approximately $2.25 billion dollars a year to public schools, public libraries, and public hospitals. the vast majority of e-rate funding—about 90 percent—goes to public schools each year, with roughly 4 percent being awarded to public libraries and the remainder going to hospitals.13 the emphasis on funding schools results from the large number of public schools and the sizeable computing needs of all of these schools. but even 4 percent of the e-rate funding is quite substantial, with public libraries receiving more than $250 million between 2000 and 2003.14 schools received about $12 billion in the same time period.15 along with e-rate funds, the library services and technology act (lsta) program administered by the imls provides money to each state library agency to use on library programs and services in that state, though the amount of these funds is considerably lower than e-rate funds. the american library association (ala) has noted that the e-rate program has been particularly significant in its role of expanding online access to students and to library patrons in both rural and underserved communities.16 in addition to the effect on libraries, e-rate and lsta funds have significantly affected the lives of individuals and communities. these programs have contributed to the increase in the availability of free public internet access in schools and libraries. by 2001, more than 99 percent of public school libraries provided students with internet access.17 by 2007, 99.7 percent of public library branches were connected to the internet, and 99.1 percent of public library branches offered public internet access.18 however, only a small portion of libraries and schools used filters prior to cipa.19 since the advent of computers in libraries, librarians typically had used informal monitoring practices for computer users to ensure that nothing age inappropriate or morally offensive was publicly visible.20 some individual school and library systems, such as in kansas and indiana, even developed formal or informal statewide internet safety strategies and approaches.21 why were only libraries and schools chosen to protect children’s online safety? while there are many social institutions that could have been the focus of cipa, the law places the requirements specifically on public libraries and public schools. if congress was so interested in protecting children from access to harmful internet content, it seems that the law would be more expansive and focused on the content itself rather than filtering access to the content. however, earlier laws that attempted to regulate access to internet content failed legal challenges specifically because they tried to regulate content. prior to the enactment of cipa, there were a number of other proposed laws aimed at preventing minors from accessing inappropriate internet content. the communications decency act (cda) of 1996 prohibited the sending or posting of obscene material through the internet to individuals under the age of eighteen.22 however, the supreme court found the cda to be unconstitutional, stating that the law violated free speech under the first amendment. in 1998, congress passed the child online protection act (copa), which prohibited commercial websites from displaying material deemed harmful to minors and imposed criminal penalties on internet violators.23 a three-panel judge for the district court for the eastern district of pennsylvania ruled that copa’s focus on “contemporary community standards” violated the first amendment, and the panel subsequently imposed an one law with two outcomes | jaeger and yan 9 injunction on copa’s enforcement. cipa’s force comes from congress’s power under the spending clause; that is, congress can legally attach requirements to funds that it gives out. since cipa is based on economic persuasion—the potential loss of funds for technology—the law can only have an effect on recipients of those funds. while regulating internet access in other venues like coffee shops, internet cafés, bookstores, and even individual homes would provide a more comprehensive shield to limit children’s access to certain online content, these institutions could not be reached under the spending clause. as a result, the burdens of cipa fall squarely on public libraries and public schools. n the current state of filtering when did cipa actually come into effect in libraries and schools? after overcoming a series of legal challenges that were ultimately decided by the supreme court, cipa came into effect in full force in 2003, though 96 percent of public schools were already in compliance with cipa in 2001. when the court upheld the constitutionality of cipa, the legal challenge by public libraries centered on the way the statute was written.24 the court’s decision states that the wording of the law does not place unconstitutional limitations on free speech in public libraries. to continue receiving federal dollars directly or indirectly through certain federal programs, public libraries and schools were required to install filtering technologies on all computers. while the case decided by the supreme court focused on public libraries, the decision virtually precludes public schools from making the same or related challenges.25 before that case was decided, however, most schools had already adopted filters to comply with cipa. as a result of cipa, a public library or public school must install technology protection measures, better known as filters, on all of its computers if it receives n e-rate discounts for internet access costs, n e–rate discounts for internal connections costs, n lsta funding for direct internet costs,26 or n lsta funding for purchasing technology to access the internet. the requirements of cipa extend to public libraries, public schools, and any library institution that receives lsta and e–rate funds as part of a system, including state library agencies and library consortia. as a result of the financial incentives to comply, almost 100 percent of public schools in the united states have implemented the requirements of cipa,27 and approximately half of public libraries have done so.28 how many public schools have implemented cipa? according to the latest report by the department of education (see table 1), by 2005, 100 percent of public schools had implemented both the internet filtering strategy and safety policy strategy. in fact, in 2001 (the first year cipa was in effect), 96 percent of schools had implemented cipa, with 99 percent filtering by 2002. when compared to the percentage of all public schools with internet access from 1994 to 2005, internet access became nearly universal in schools between 1999 and 2000 (95 to 98 percent), and one can see that the internet access percentage in 2001 was almost the same as the cipa implementation percentage. according to the department of education, the above estimations are based on a survey of 1,205 elementary and secondary schools selected from 63,000 elementary schools and 21,000 secondary and combined schools.29 after reviewing the design and administration of the survey, it can be concluded that these estimations should be considered valid and reliable and that cipa was immediately and consistently implemented in the majority of the public schools since 2001.30 how many public libraries have implemented cipa? in 2002, 43.4 percent of public libraries were receiving e-rate discounts, and 18.9 percent said they would not apply for e-rate discounts if cipa was upheld.31 since the supreme court decision upholding cipa, the number of libraries complying with cipa has increased, as table 1. implementation of cipa in public schools year 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2005 access (%) 35 50 65 78 89 95 98 99 99 100 100 filtering (%) 96 99 97 100 10 information technology and libraries | march 2009 have the number of libraries not applying for e-rate funds to avoid complying with cipa. however, unlike schools, there is no exact count of how many libraries have filtered internet access. in many cases, the libraries themselves do not filter, but a state library, library consortium, or local or state government system of which they are a part filters access from beyond the walls of the library. in some of these cases, the library staff may not even be aware that such filtering is occurring. a number of state and local governments have also passed their own laws to encourage or require all libraries in the state to filter internet access regardless of e-rate or lsta funds.32 in 2008, 38.2 percent of public libraries were filtering access within the library as a result of directly receiving e-rate funding.33 furthermore, 13.1 percent of libraries were receiving e-rate funding as a part of another organization, meaning that these libraries also would need to comply with cipa’s requirements.34 as such, the number of public libraries filtering access is now at least 51.3 percent, but the number will likely be higher as a result of state and local laws requiring libraries to filter as well as other reasons libraries have implemented filters. in contrast, among libraries not receiving e-rate funds, the number of libraries now not applying for e-rate intentionally to avoid the cipa requirements is 31.6 percent.35 while it is not possible to identify an exact number of public libraries that filter access, it is clear that libraries overall have far lower levels of filtering than the 100 percent of public schools that filter access. e-rate and other program issues the administration of the e-rate program has not occurred without controversy. throughout the course of the program, many applicants for and recipients of the funding have found the program structure to be obtuse, the application process to be complicated and time consuming, and the administration of the decision-making process to be slow.36 as a result, many schools and libraries find it difficult to plan ahead for budgeting purposes, not knowing how much funding they will receive or when they will receive it.37 there also have been larger difficulties for the program. following revelations about the uses of some e-rate awards, the fcc suspended the program from august to december 2004 to impose new accounting and spending rules for the funds, delaying the distribution of over $1 billion in funding to libraries and schools.38 news investigations had discovered that certain school systems were using e-rate funds to purchase more technology than they needed or could afford to maintain, and some school systems failed to ever use technology they had acquired.39 while the administration of the e-rate program has been comparatively smooth since, the temporary suspension of the program caused serious short-term problems for, and left a sense of distrust of, the program among many recipients.40 filtering issues during the 1990s, many types of software filtering products became available to consumers, including serverside filtering products (using a list of server-selected blocked urls that may or may not be disclosed to the user), client-side filtering (controlling the blocking of specific content with a user password), text-based content-analysis filtering (removing illicit content of a website using real-time analysis), monitoring and timelimiting technologies (tracking a child’s online activities and limiting the amount of time he or she spends online), and age-verification systems (allowing access to webpages by passwords issued by a third party to an adult).41 but because filtering software companies make the decisions about how the products work, content and collection decisions for electronic resources in schools and public libraries have been taken out of the hands of librarians, teachers, and local communities and placed in the trust of proprietary software products.42 some filtering programs also have specific political agendas, which many organizations that purchase them are not aware of.43 in a study of over one million pages, for every webpage blocked by a filter as advertised by the software vendor, one or more pages were blocked inappropriately, while many of the criteria used by the filtering products go beyond the criteria enumerated in cipa.44 filters have significant rates of inappropriately blocking materials, meaning that filters misidentify harmless materials as suspect and prevent access to harmless items (e.g., one filter blocked access to the declaration of independence and the constitution).45 furthermore, when libraries install filters to comply with cipa, in many instances the filters will frequently be blocking text as well as images, and (depending on the type of filtering product employed) filters may be blocking access to entire websites or even all the sites from certain internet service providers. as such, the current state of filtering technology will create the practical effect of cipa restricting access to far more than just certain types of images in many schools and libraries.46 n differences in the perceived value of cipa and filtering based on the available data, there clearly is a sizeable contrast in the levels of implementation of cipa between one law with two outcomes | jaeger and yan 11 schools and libraries. this difference raises a number of questions: for what reasons has cipa been much more widely implemented in schools? is this issue mainly value driven, dollar driven, both, or neither in these two public institutions? why are these two institutions so different regarding cipa implementation while they share many social and educational similarities? reasons for nationwide full implementation in schools there are various reasons—from financial, population, social, and management issues to computer and internet availability—that have driven the rapid and comprehensive implementation of filters in public schools. first, public schools have to implement cipa because of societal pressures and the lobbying of parents to ensure students’ internet safety. almost all users of computers in schools are minors, the most vulnerable groups for internet crimes and child pornography. public schools in america have been the focus of public attention and scrutiny for years, and the political and social responsibility of public schools for children’s internet safety is huge. as a result, society has decided these students should be most strongly protected, and cipa was implemented immediately and most widely at schools. second, in contrast to public libraries (which average slightly less than eleven computers per library outlet), the typical number of computers in public schools ranges from one hundred to five hundred, which are needed to meet the needs of students and teachers for daily learning and teaching. since the number of computers is quite large, the financial incentives of e-rate funding are substantial and critical to the operation of the schools. this situation provides administrators in schools and school districts with the incentive to make decisions to implement cipa as quickly and extensively as possible. furthermore, the amount of money that e-rate provides for schools in terms of technology is astounding. as was noted earlier, schools received over $12 billion from 2000 to 2003 alone. schools likely would not be able to provide the necessary computers for students and teachers without the e-rate funds. third, the actual implementation procedure differs in schools and libraries: schools are certified under the supervision of the local educational agencies such as school districts and state departments of education; libraries are certified within a library organization under the supervision of the imls. in other words, the certification process at schools is directly and effectively controlled by school districts and state departments of education, following the same fundamental values of protecting children. the resistance to cipa in schools has been very small in comparison to libraries. the primary concern raised has been the issue of educational equality. concerns have been raised that filters in schools may create two classes of students—ones with only filtered access at school and ones who also can get unfiltered access at home.47 reasons for more limited implementation in libraries in public libraries, the reasons for implementing cipa are similar to those of public schools in many ways. public libraries provide an average of 10.7 computers in each of the approximately seven thousand public libraries in the united states, which is a lot of technology that needs to be supported. the e-rate and lsta funds are vital to many libraries in the provision of computers and the internet. furthermore, with limited alternative sources of funding, the e-rate and lsta funds are hard to replace if they are not available. given that the public libraries have become the guarantor of public access to computing and the internet, libraries have to find ways to ensure that patrons can access the internet.48 libraries also have to be concerned about protecting and providing a safe environment for younger patrons. while libraries serve patrons of all ages, one of the key social expectations of libraries is the provision of educational materials for children and young adults. children’s sections of libraries almost always have computers in them. much of the content blocked by filters is of little or no education value. as such, “defending unfiltered internet access was quite different from defending catcher in the rye.”49 nevertheless, many libraries have fought against the filtering requirements of cipa because they believe that it violates the principles of librarianship or for a number of other reasons. in 2008, 31.6 percent of public libraries refused to apply for e-rate or lsta funds specifically to avoid cipa requirements, a substantial increase from the 15.3 percent of libraries that did not apply for e-rate because of cipa in 2006.50 as a result of defending patron’s rights to free access, the libraries that are not applying for e-rate funds because of the requirements of cipa are being forced to turn down the chance for funding to help pay for internet access in order to preserve community access to the internet. because many libraries feel that they cannot apply for e-rate funds, local and regional discrepancies are occurring in the levels of internet access that are available to patrons of public libraries in different parts of the country.51 for adult patrons who wish to access material on computers with filters, cipa states that the library has the option of disabling the filters for “bona fide research or other lawful purposes” when adult patrons request such disabling. the law does not require libraries to 12 information technology and libraries | march 2009 disable the filters for adult patrons, and the criteria for disabling of filters do not have a set definition in the law. the potential problems in the process of having the filters disabled are many and significant, including librarians not allowing the filters to be turned off, librarians not knowing how to turn the filters off, the filtering software being too complicated to turn off without injuring the performance of the workstation in other applications, or the filtering software being unable to be turned off in a reasonable amount of time.52 it has been estimated that approximately 11 million low-income individuals rely on public libraries to access online information because they lack internet access at home or work.53 the e-rate and lsta programs have helped to make public libraries a trusted community source of internet access, with the public library being the only source of free public internet access available to all community residents in nearly 75 percent of communities in the united states.54 therefore usage of computers and the internet in public libraries has continued to grow at a very fast pace over the past ten years.55 thus public libraries are torn between the values of providing safe access for younger patrons and broad access for adult patrons who may have no other means of accessing the internet. n cipa, public policy, and further research while the diverse implementations, effects, and levels of acceptance of cipa across schools and libraries demonstrate the wide range of potential ramifications of the law, surprisingly little consideration is given to major assumptions in the law, including the appropriateness of the requirements to different age groups and the nature of information on the internet. cipa treats all users as if they are the same level of maturity and need the same level of protection as a small child, as evidenced by the requirement that all computers in a library or school have filters regardless of whether children use a particular computer. in reality, children and adults interact in different social, physical, and cognitive ways with computers because of different developmental processes.56 cipa fails to recognize that children as individual users are active processors of information and that children of different ages are going to be affected in divergent ways by filtering programs.57 younger children benefit from more restrictive filters while older children benefit from less restrictive filters. moreover, filtering can be complimented by encouragement of frequent positive internet usage and informal instruction to encourage positive use. finally, children of all ages need a better understanding of the structure of the internet to encourage appropriate caution in terms of online safety. the internet represents a new social and cultural environment in which users simultaneously are affected by the social environment and also construct that environment with other users.58 cipa also is based on fundamental misconceptions about information on the internet. the supreme court’s decision upholding cipa represents several of these misconceptions, adopting an attitude that ‘we know what is best for you’ in terms of the information that citizens should be allowed to access.59 it assumes that schools and libraries select printed materials out of a desire to protect and censor rather than recognizing the basic reality that only a small number of print materials can be afforded by any school or library. the internet frees schools and libraries from many of these costs. furthermore, the court assumes that libraries should censor the internet as well, ultimately upholding the same level of access to information for adult patrons and librarians in public libraries as students in public schools. these two major unexamined assumptions in the law certainly have played a part in the difficulty of implementing cipa and in the resistance to the law. and this does not even address the problems of assuming that public libraries and public schools can be treated interchangeably in crafting legislation. these problematic assumptions point to a significantly larger issue: in trying to deal with the new situations created by the internet and related technology, the federal government has significantly increased the attention paid to information policy.60 over the past few years, government laws and standards related to information have begun to more clearly relate to social aspects of information technologies such as the filtering requirements of cipa.61 but the social, economic, and political ramifications for decisions about information policy are often woefully underexamined in the development of legislation.62 this paper has documented that many of the reasons for and statistics about cipa implementation are available by bringing together information from different social institutions. the biggest questions about cipa are about the societal effects of the policy decisions: n has cipa changed the education and informationprovision roles of libraries and schools? n has cipa changed the social expectations for libraries and schools? n have adult patron information behaviors changed in libraries? n have minor patron information behaviors changed in libraries? n have student information behaviors changed in school? n how has cipa changed the management of libraries and schools? n will congress view cipa as successful enough to merit using libraries and schools as the means of enforcing other legislation? one law with two outcomes | jaeger and yan 13 but these social and administrative concerns are not the only major research questions raised by the implementation of cipa. future research about cipa not only needs to focus on the individual, institutional, and social effects of the law. it must explore the lessons that cipa can provide to the process of creating and implementing information policies with significant societal implications. the most significant research issues related to cipa may be the ones that help illuminate how to improve the legislative process to better account for the potential consequences of regulating information while the legislation is still being developed. such cross-disciplinary analyses would be of great value as information becomes the center of an increasing amount of legislation, and the effects of this legislation have continually wider consequences for the flow of information through society. it could also be of great benefit to public schools and libraries, which, if cipa is any indication, may play a large role in future legislation about public internet access. references 1. children’s internet protection act (cipa), public law 106554. 2. united states

jerry borrell: congressional research service, library of congress , washington , d.c* this brief article will review videotex and teletext. there is little need to define terminology because new hybrid systems are being devised almost constantly (hats off to oclc's latest buzzword-viewtel). ylost useful of all would be an examination of the types of technology being used for information provision. the basic requirement for all systems is a data base-i.e ., data stored so as to allow its retrieval and display on a television screen. the interactions between the computer and the television screens are means to distinguish technologies. in teletext and videotex a device known as a decoder uses data encoded onto the lines of a broadcast signal (whatever the medium of transmission ) to generate the display screen. in videotex, voice grade telephone lines or interactive cable are used to carry data communications between two points (usually 1200 baud from the computer and 300 baud or less from the decoder and th e television screen). in teletext the signal is broadcast over airwaves (wideband) or via a time-sharing system (narrowband). the numerous configurations possible make straightforward classification of syst e ms questionable. a review of the systems currently available is useful to illustrate these terms, videotex and teletext. compuserve, the columbus, ohio-based company, provides on-line searching of newspapers to about 4,000 users. reader's digest recently acquired 51 percent of the source, a time*the views expressed in this paper do not necessarily represent those of the library of congress or of the congressional research ser~ vice. sharing service that provides more than 100 different (nonbibliographic) data bases to about 5,000 users. the warner and american express joint project, qube (also columbus-based), utilizes cable broadcast with a limited interactive capability . it does not allow for on-demand provision of information ; rather, it uses a polling technique. antiope, the french teletext system, used at ksl in st. louis last year and undergoing further tests in los angeles at knxt in the coming year, is only part of a complex data transmission system known as didon. antiope is also at an experimental stage in france, with 2,500 terminals scheduled for use in 1981. ceef ax and oracle , broadcast teletext by the bbc and ibc in britain, have an estimated 100,000 users currently. two thousand adapted television sets are being sold every month . prestel, bbc's videotex system, currently has approximately 5,000 users, half of whom are businesses. all other countries in europe are conducting experiments with one of the technologies. in canada, telidon, the most technically advanced system, has 200 users. experiments involving telidon are being conducted nationwide due to government interest in telecommunications improvements. telidon will also be used in washington in the spring of 1981 for consumer evaluation. these cursory notes should indicate the breadth of interes t in alternative means of information provision. video and electronic publishing newsletters (see references) keep track of the number of users and are the best way to keep informed of activities and developments. several important trends are becoming evident. perhaps the most evident is the realization that videography is being developed in countries other than the u.s. as a result of strong support by the national posts and telecommunications (ptt) authorities . until recently there was a feeling that the u.s. was technically behind europe. what is now evident is that in the free market system of the u . s. manufacturers or other potential system providers have had insufficient impetus to provide videotex/teletext technology. the technology of information display (see borrell, journal of library automation, v.13 (dec. 1980), p.277-81) in the u.s. is an order of magnitude more sophisticated than in europe. the point being that in the absence of strong ptt pressure, videography in the u . s. developed for specialized markets in which telecommunications were not a central need. in the one area of great demand, teletext services for the hearing impaired, decoders were developed and have been employed for a number of years (about 25,000 are currently in use ). as the high cost of telecommunications bandwidth is eased by data compression, direct broadcasting by satellite, enhanced cable services, and fiber optic networks, then videotex and te letext will become available on a wide scale in the u.s. the computer inquiry ii decision by the fcc involving reinterpretation of the communications act of 1934 has given at&t permission to enter the data processing market . in fact, at&t, in its third experiment with videotex, is taking such an aggressive stance that it seems to be doing everything that its critics have feared: providing updatable classified ads (dynamic yellow pages), allowing users to place information into the system memory , and providing voice mail servicesthereby taking on the newspapers, home computer manufacturers, and the u . s. postal service. in addition, banking services will be offered . as the largest company in the u.s ., this stance cannot be ignored. at&t supplies about 80 percent of the phone service in the u .s., and has the potential, if allowed , to become a broadcaster, data processor, publisher, and banker ; cross-ownership was never allowed up to this time . the trend toward specialized services provision is also exemplified by the communications 51 french and british systems. prestel , which was originally targeted for a home market, is now promoted with the tacit policy of being a special business service allowing financial and private data to be provided to subscribers. sofratev, the marketers of the french teletext system, are acknowledging the importance of transactional markets in two ways, based on technology they have named "smart card," a credit card-size (in one configuration) plate with a built-in microprocessor or chip. the card will allow system users to access material that will have controlled readership. an example would be a magazine of financial data provided to those who need such information (or, more importantly, are willing to pay for it). in a more complex effort, the largest retailer in paris will advertise material via teletext and system users will be able to make acquisitions with their smart card, which can be programmed with financial data. nor is this the end of the effort by the french to market information display technology. the electronic phone directory, being offered by bell in austin , is replicated in a more modest way by the french, who plan to produce a six-byeight-inch black-and,white display unit that will provide. phone directory information (both white and yellow pages) to all of france by the 1990s. developed as part of the "telerriatique" program of the .french government, the terminals represent to some (the parent company of the source has tendered an offer for up to 250,000 of the terminals) a low-cost alternative for providing videotex to a mass market. the tandy home computer in its videotex configuration seems to fill the same market slot. perhaps the most disturbing trend, at least from a librarian's point of view, is the fact that contemporary data systems are being created which could benefit greatly from the experience of librarians and libraries. for instance, research into the methods of access-keyword, phonetic and geographical-by the french is intended to pro:vide a flexible and easily used system for untrained persons searching for directory information, and is being performed by an advertising and yellow pages 52 journal of library automation vol. 14/1 march 1981 publishing firm. with a feeling of deja vu i listened to an explanation of how difficult it is to develop a system for the novice; one proposed solution is to allow only the first four letters of a word to be entered (one of the search methods used at the library of congress, which does suggest some cross-fertilization ). whatever the trends, the reality is that librarians and information scientists are playing decreasing roles in the growth of information display technology. hardware systems analysts, advertisers, and communications specialists are the main professions that have an active role to play in the information age. perhaps the answer is an immediate and radical change in the training of library schools of today. our small role may reflect our penchant to be collectors, archivists, and guardians of the information repositories . have we become the keepers of the system? the demand today is for service, information, and entertainment. if we librarians cannot fulfill these needs our places are not assured. should the american library association (ala) be ensuring that libraries are a part of all ongoing tests of videotex-at least in some way-either as organizers, information providers, or in analysis? consider the force of the argument given at the ala 1980 new york annual conference that cable television should be a medium that librarians become involved with for the future. certainly involvement is an important role, but we , like the industrialists and marketers before us, must make smart decisions and choose the proper niche and the most effective way to use our limited resources if we are to serve any part of society in the future. bibliography 1.

and with them comes the ever broadening application of the computer. this presents a new challenge to libraries. what do we do with all these computer codes? how do we index the material? and most importantly, how do we make it accessible to our patrons or computer users? bechtel's data processing library has met these demands. the genesis for th e collection was bechte l's conversion from a honeywell 6000 computer to a univac lloo in 1974. all the programs in use at that time were converted to run on the univac system. it seemed a good time to put all of the computer programs together from all of the various bechtel divisions into a controlled collection. the librarians were charged with the responsibility of enforcing standards and control of bechtel's computer programs. the major benefits derived from placing all computer programs into a controlled library were: 1. company-wide usage of the programs. 2. minimize investment in program development through common usage. 3. computer file and documentation storage by the library to safeguard the investment. 4. central location for audits of program code and documentation. 5. centralized reporting on bechtel programs . developing the collection involved basic cataloging techniques which were greatly modified to encompass all the information that computer programs generate, including actual code, documentation, and listhigh-performance annotation tagging over solr full-text indexes michele artini, claudio atzori, sandro la bruzzo, paolo manghi, marko mikulicic, and alessia bardi information technology and libraries | september 2014 22 abstract in this work, we focus on the problem of annotation tagging over information spaces of objects stored in a full-text index. in such a scenario, data curators assign tags to objects with the purpose of classification, while generic end users will perceive tags as searchable and browsable object properties. to carry out their activities, data curators need annotation tagging tools that allow them to bulk tag or untag large sets of objects in temporary work sessions where they can virtually and in real time experiment with the effect of their actions before making the changes visible to end users. the implementation of these tools over full-text indexes is a challenge because bulk object updates in this context are far from being real-time and in critical cases may slow down index performance. we devised tagtick, a tool that offers to data curators a fully functional annotation tagging environment over the full-text index apache solr, regarded as a de facto standard in this area. tagtick consists of a tagtick virtualizer module, which extends the api of solr to support real-time, virtual, bulk-tagging operations, and a tagtick user interface module, which offers end-user functionalities for annotation tagging. the tool scales optimally with the number and size of bulk tag operations without compromising the index performance. introduction tags are generally conceived as nonhierarchical terms (or keywords) assigned to an information object (e.g., a digital image, a document, a metadata record) in order to enrich its description beyond the one provided by object properties. the enrichment is intended to improve the way end users (or machines) can search, browse, evaluate, and select the objects they are looking for. examples are qualificative terms, i.e. terms associating the object to a class (e.g., biology, computer science, literature) or qualitative terms, i.e. terms associating the object to a given measure of value (e.g., rank in a range, opinion).1 approaches differ in the way tags are generated. in some cases users (or machines)2 freely and collaboratively produce tags,3 thereby generating so-called michele artini (michele.artini@isti.cnr), claudio atzori (claudio.atzori@isti.cnr.it), sandro la bruzzo (msandro.labruzzo@isti.cnr), paolo manghi (paolo.manghi@iti.cnr.it), and mark

indexes | artini et al 23 folksonomies. the natural heterogeneity of folksonomies calls for solutions to harmonise and make more effective their usage, such as tag clouds.4 in other approaches users can pick tags from a given set of values (e.g., vocabulary, ontology, range) or else find hybrid solutions, where a degree of freedom is still permitted.5,6 a further differentiation is introduced by semantically enriched tags, which are tags contextualized by a label or prefix that provides an interpretation for the tag.7 for example, in the digital library world, the annotation of scientific article objects with subject tags could be done according to the tag values of the tag interpretations of acm scientific disciplines and “dewey decimal classification,” whose term ontologies are different.8 the action of tagging is commonly intended as the practice of end users or machines of assigning or removing tags to the objects of an information space. an information space is a digital space a user community populates with information objects for the purpose of enabling content sharing and providing integrated access to different but related collections of information objects.9 the effect of tagging information objects in an information space may be private, i.e., visible to the users who tagged the objects or to a group of users sharing the same right, or public, i.e., visible to all users.10 many well-known websites allow end users to tag web resources. for example delicious11 (http://delicious.com) allows users to tag web links with free and public keywords; stack overflow (http://stackoverflow.com), which lets users ask and answer questions about programming, allows tagging of question threads with free and public keywords; gmail 12 (http://mail.gmail.com) allows users to tag emails—at the same time, tags are also transparently used to encode email folders. in the digital library context, the portal europeana (http://www.europeana.eu) allows authenticated end users to tag metadata records with free keywords to create a private set of annotations. in this work we shall focus on annotation tagging—that is, tagging used as a manual data curation technique to classify (i.e., attach semantics to) the objects of an information space. in such a scenario, tags are defined as controlled vocabularies whose purpose is classification.13,14 unlike semantic annotation scenarios, where semantic tags may be semiautomatically generated and assigned to objects,15 in annotation tagging authorized data curators are equipped with search tools to identify the sets of objects they believe should belong or not belong to a given category (identified by a tag), and to eventually perform the tagging or untagging actions required to apply the intended classification. in general, such operations may assign or remove tags to and from an arbitrarily large subset of objects of the information space. it is therefore hard to predict the quality and consistency of the combined effect of a number of such actions. as a consequence, data curators must rely on virtual tagging functionalities which allow them to bulk (un)tag sets of objects in temporary work sessions, where they can in real-time preview and experiment (do/undo) the effects of their actions before making the changes visible to end users. examples of scenarios that may require annotation tagging can be found in many fields of application. this is the case, for example, in several data infrastructures funded by the european commission fp7 program, which share the common goal of populating very large information spaces by aggregating textual metadata records collected from several data sources. examples are the data http://delicious.com/ http://stackoverflow.com/ http://mail.gmail.com/ http://www.europeana.eu/ information technology and libraries | september 2014 24 infrastructures for driver,16 heritage of the people’s europe (hope),17 european film gateway (efg and efg1914),18 openaire19 (http://www.openaire.eu), and europeana. in such contexts, the aggregated records are potentially heterogeneous, not sharing common classification schemes, and annotation tagging becomes a powerful mean to make the information space more effectively consumable by end users. there at two significant challenges to be tackled in the realization of annotation tagging tools. first is the need to support bulk-tagging actions in almost real time so that data curators need not wait long for their actions to complete. second, bulk-tagging actions need to be virtualized over the information space, so that data curators can verify the quality of their actions before committing them, and access to the information space is unaffected by such actions. naturally, the feasibility and quality of annotation tagging tools strictly depends on the data management system adopted to index and search objects of the information space. in general, not to compromise information space availability, bulk-updates are based on offline, efficient strategies, which minimize the update’s delay,20 or virtualisation techniques, which perform the update in such a way that users have the impression this was completed.21 in this work, we target the specific problem of annotation tagging of information spaces whose objects are documents in a solr full-text index (v3.6).22 solr is an open-source apache project delivering a full-text index whose instances are capable of scaling up to millions of records, can benefit from horizontal clustering, replica handling, and production-quality performance for concurrent queries and bulk updates. the index is widely adopted in the literature and often in contexts where annotation tagging is required, such as the aforementioned aggregative data infrastructures. the implementation of virtual and bulk-tagging facilities over solr information spaces is a challenge, since bulk updates of solr objects are fast, but far from being real-time when large sets of objects are involved. in general, independently of the configuration, a re-indexing of millions of objects may take up to some hours, while for real-time previews even minutes would not be acceptable. moreover, in critical cases, update actions may also slow down index performance and compromise access to the information space. in this paper, we present tagtick, a tool that implements facilities for annotation tagging over solr with no remarkable degradation of performances with respect to the original index. tagtick consists of two main modules: the tagtick virtualizer, which implements functionalities for realtime bulk (un)tagging in the context of work sessions for solr, and the tagtick user interface, which implements user interfaces for data curators to create, operate and commit work sessions, so as to produce newly tagged information spaces. tagtick software can be demoed and downloaded from http://nemis.isti.cnr.it/product/tagtick-authoritative-tagging-apache-solr. annotation tagging annotation tagging is a process operated by data curators whose aim is improving the end user’s search experience over an information space. specifically, the activity consists in assigning searchable and browsable tags to objects in order to classify and logically structure the http://www.openaire.eu/ http://nemis.isti.cnr.it/product/tagtick-authoritative-tagging-apache-solr high-performance annotation tagging over solr full-text indexes | artini et al 25 information space into further (and possibly overlapping) meta-classes of objects. moreover, when ontologies published on the web are used, for example ontologies available as linked data such as the geonames ontology (http://www.geonames.org/ontology/documentation.html) or the dbpedia ontology (http://dbpedia.org/ontology), then tags are means to link objects in the information space to external resources. in this section, we shall describe the functional requirements of annotation tagging in order to introduce assumptions and nomenclature to be used in the remainder of the paper. information space: objects, classes, tags, and queries we define an information space as a set of objects of different classes c1 . . . ck. each class ci has a structure (l1 : v1, . . . ,ln : vn), where lj’s are object property labels and vj are the types of the property values. types can be value domains, such as strings, integers, dates, or controlled vocabularies of terms. in its general definition, annotation tagging has to do with semantically enriched tagging, where a tag consists of a pair (i, t), made of a tag interpretation i and a tag value t from a term ontology t; as an example of interpretation consider the acm subject classification scheme (e.g., i = acm), where t is the set of acm terms. in this context, tagging is de-coupled from the information space and can be configured aposteriori. typically, given an information space, data curators set up the annotation tagging environment by: (i) defining the interpretation/ontology pairs to be used for classification, and (ii) assigning to each class c the interpretations to be used to tag its objects. as a result, class structures are enriched with a set of interpretations (i1:t1 . . . im:tm), where ij are tag interpretation labels and tj the relative ontologies. unless differently specified, an object may be assigned multiple tag values for the same tag interpretation, e.g. scientific publication objects may cover different scientific acm disciplines. finally, the information space can reply to queries q formed according to the abstract syntax intable 1, where op is a generic boolean operator (dependent on the underlying data management system, e.g. “=,” “<,” “>”) and c∈{c1, . . . ,ck}. tag predicates (i = t) and class predicates (class = c) represent exact matches, which mean “the object is tagged with the tag (i, t)” and “the object belongs to class c.” q ∷=(q and q) | (q or q) | (l op v) | (i = t) | (class = c) | v | ε table 1. solr query language. http://www.geonames.org/ontology/documentation.html http://dbpedia.org/ontology information technology and libraries | september 2014 26 virtual and real-time tagging in annotation tagging data curators apply bulk (un)tagging actions with respect to a tag (i, t) over arbitrarily large sets of objects returned by queries q over the information space. due to the potential impact that such operations may have over the information space, tools for annotation tagging should allow data curators to perform their actions in a protected environment called work session. in such an environment curators can test sequences of bulk (un)tagging actions and incrementally shape up an information space preview: they may view the history of such actions, undo some of them, add new actions, and pose queries to test the quality of their actions. to offer a usable annotation tagging tool, it is mandatory for such actions to be performed in (almost) realtime. for example, curators should not wait more than a few seconds to test the result of tagging 1 million objects, an action which they might undo immediately after. moreover, such actions should not conflict (e.g., slow performance) with the activities of end users running queries on the information space. finally, when data curators believe the preview has reached its maturity, they can commit the work session, i.e., materialise the preview in the information space, and make the changes visible to end users. apache solr and annotation tagging as mentioned in the introduction, our focus is on annotation tagging for apache solr (v3.6). this section describes the main information space features and functionalities of the solr full-text index search platform. in particular, it explains the issues arising when using its native apis to implement bulk real-time tagging as described previously. solr information spaces: objects, classes, tags, and queries solr is one of the most popular full-text indexes. it is an apache open source java project that offers a scalable, high performance and cross-platform solution for efficient indexing and querying of information spaces made of millions of objects (documents in solr jargon).23 a solr index stores a set of objects, each consisting in a flat list of possibly replicated and unordered fields associated to a value. each object is referable by a unique identifier generated by the index at indexing time. the information spaces described previously can be modelled straightforwardly in solr. each object in the index contains field-value pairs relative to the properties and tag interpretations of all classes they belong to. moreover, we shall assume that all objects share one field named class whose values indicate the classes (e.g. c1, . . . ,ck) to which the object belongs. such an assumption does not restrict the application domain, since classes are typically encoded in solr by a dedicated field. the solr api provides methods to search objects by general keywords, field values, field ranges, fuzzy terms and other advanced search options, plus methods for the bulk addition and deletion of objects. in our study, we shall restrict to the search method query(q, qf), where q and qf are cql queries respectively referred as the “main query” and the “filter query”. in particular, in order to match the query language requirements described previously, we shall assume that q and qf are high-performance annotation tagging over solr full-text indexes | artini et al 27 expressed according to the cql subset matching the query language in table 1. getdocset :rs→ds returns the docset relative to a result set intersectdocsets :ds × ds→ds returns the intersection of two docset intersectsize :ds × ds→integer returns the size of the intersection of two docsets unifydocsets :ds × ds→ds returns the union of two docsets andnotdocsets :ds × ds→ds given two docsets ds1 and ds2 returns the docset {d | d ∈ ds1 ⋀ ¬ d ∈ ds2} searchondocsets :q × ds→rs executes a query q over a docset and returns the relative resultset table 2. solr docset management low-level interface. to describe the semantics of query(q, qf) it is important to make a distinction between the solr notions of result set and docset. in solr, the execution of a query returns a result set (i.e., queryresponse in solr jargon) that logically contains all objects matching the query. in practice, a result set is conceived to be returned at the time of execution to offer instant access to the query result, which is meantime computed and stored in memory into a low-level solr data structure called docset. docsets are internal solr data structures, which contain lists of object identifiers and allow for efficient operations such as union and intersection of very large sets of objects to optimize query execution. table 1 illustrates some of the methods used internally by solr to handle docsets. method names have been chosen to be self-explanatory and therefore do not match the ones used in the libraries of solr. information technology and libraries | september 2014 28 ⟦query(q,qf)⟧solr= � {d|id(d)∈ ⟦q⟧ds} if (qf=null) searchondocset(q, ⟦qf⟧cache(ϕ)) if (qf ≠null) ⟦qf⟧cache(ϕ)= � ds if

functions. informally, query(q, qf) returns the result set of objects matching the query q intersected with the objects matching the filter query qf, i.e. its semantics is equivalent to the one of the command query(q and qf, null). in practice, the usage of a filter query qf is intended to efficiently reduce the scope of q to the set of objects whose identifiers are in the docset of qf. to this aim, solr keeps in memory a filter cache ϕ:q →ds. the first time a filter query qf is received, solr executes it and stores the relative docset ds in ϕ, where it can be accessed to optimize the execution of query(q, qf). once the docset ϕ(qf) = ds is available, query(q, qf) invokes the low-level method searchondocset(q, ds) (see table 1). the method executes q to obtain its docset, efficiently intersects such docset with ds, and populates the result set relative to the query. due to the efficiency of docset intersection and in-memory data structures, query execution time is closely limited to the one necessary to execute q. table 3 shows the semantic functions ⟦.⟧solr :q x q →rs , ⟦.⟧ds :q →ds, ⟦.⟧cache :q x ℘(q x ds) → ds. the first yields the result set of query(q, qf); the second the docset relative to a query q (where d is an object); and the third resolves queries into docsets by means of a filter cache ϕ. limits to virtual and real-time tagging in solr whilst solr is a well-known and established solution for full-text indexing over very large information spaces, it poses challenges for higher-level applications willing to expose to users private, modifiable views of the same index. this is the case for annotation tagging tools, which must provide data curators with work sessions where they can update with tagging and untagging actions a logical view of the information space, while still providing end users with search facilities over the last committed information space. since solr api does not natively provide “view management” primitives, the only approach would be that of materializing tagging and untagging high-performance annotation tagging over solr full-text indexes | artini et al 29 actions in the index while making sure that such changes are not visible to end users. prefixing tags with work session identifiers, cloning of tagged objects, or keeping index replicas may be valuable techniques, but all fail to deliver the real-time requirement described previously. this is due to the fact that when very large sets of objects are involved the re-indexing phase is generally far from being real-time. in general, independently of the configuration, processing such requests may take up to some hours for millions of objects, while for real-time previews even minutes would not be acceptable. tagtick virtualizer: virtual real-time tagging for solr this section presents the tagtick virtualizer module, as the solution devised to overcome the inability of apache solr to support out-of-the-box real-time virtual views over information spaces. the virtualizer api, shown in table 4, supports methods for creating, deleting and committing work sessions, and, in the context of a work session: (1) performing tagging/untagging actions and (2) querying the information space modified by such actions. in the following we will describe both functional semantics and implementation of the api, given in terms of a formal symbolic notation. the semantics defines the expected behaviour of the api and is provided in terms of the semantics of solr. the implementation defines the realization of the api methods in terms of the low-level docset management library of solr. the right side of figure 1 illustrates the layering of functionalities required to implement the tagtick virtualizer module. as shown, the realization of the module required exposing the solr low-level docset library through an api. figure 1. tagtick virtualizer: the architecture. tagtick virtualizer api: the intended semantics the commands createsession() creates a new session s, intended as a sequence of (un)tagging information technology and libraries | september 2014 30 actions over an initial information space i. the command and deletesession(s) removes the session s from the environment. we denote the virtual information space obtained by modifying i with the actions in s as i(s); note that: i(𝜖) = i. createsession() creates and returns a work session s deletesession(s) deletes a work session s commitsession(s) commits a work session s action(a, rs, (i, t), s) applies the action a with (i, t)to all objects in rs in s virtquery(q, s) executes q over the information space i(s) table 4. tagtick virtualizer api: the methods. the command action(a, rs, (i, t), s), depending on the value of a being tag or untag, applies the relative action for the tag (i, t) to all objects in rs and in the context of the session s. (un)tagging actions occur in the context of a session s, hence update the scope of the information space i(s). the construction of such rs takes place in the annotation tagging tool user interface and may require several queries before all objects to be bulk (un)tagged are collected. annotation tagging tools may for example provide web-basket mechanisms to support curators in this process. the command commitsession(s) makes the virtual information space i(s) persistent, i.e., materializes the bulk updates collected in session s. once this operation is completed, the session s is deleted. the command virtquery(q, s) executes a virtual search whose semantics is that of the solr’s method query(q, null) executed over i(s). more formally, let’s extend the semantic function ⟦.⟧solr to include the information space scope of the execution, that is: ⟦query(q,qf)⟧solr i is the semantics of query(q, qf) over a given information space i. then, we can define: ⟦virtquery(q, s)⟧tv = ⟦query(q, null)⟧solr i(s) tagtick virtualizer api: the implementation to provide its functionalities in real time, the tagtick virtualizer avoids any form of update action into the index. the module emulates the application of bulk (un)tagging actions over the information space by exploiting solr low-level library for docset management, whose methods are shown in table 2. the underlying intuition is based on two considerations: (1) the action action(a, rs, (i, t), s) can be encoded in memory as an association between the tag (i, t) and the objects in the docset ds relative to rs in the context of s; and (2) the subset of objects ds should be returned to the high-performance annotation tagging over solr full-text indexes | artini et al 31 query (i = t) if executed over i in the scope of s (i.e., as if i was updated with such an action). by following this approach, the module may rewrite and execute calls of the form virtquery(q and (i = t)) into calls searchondocset(q, ds), thereby emulating the real-time execution of the query over the information space i(s). more generally, any query of the form q and qtag predicates, where qtag predicates is a query combining tag predicates relative to tags touched in the session, can be rewritten as searchondocset(q, ds). in such cases, ds is obtained by combining the docsets relative to tag predicates by means of the low-level methods intersectdocsets and unifydocsets. the tagtick virtualizer module implements the aforementioned session cache by means of an inmemory map ρ = s × i × t →ds, which caches the tagging status of all active work sessions. to this aim, ρ maps triples (s, i, t) onto docsets ds that are defined as the set of objects tagged with the tag (i, t) in the context of s at the time of the request. the tagtick virtualizer is stateless with regard to the specific tags and sessions identifiers it is called to handle; such information is typically held in applications using the module to take advantage of real-time, virtual tagging mechanisms. tagging and untagging actions the method action(a, rs, (i, t), s) has the effect of changing the status ρ to reflect the action of tagging or untagging the objects in the result set rs with the tag (i, t) in the session s. table 5 describes the effect of the command over the status ρ in terms of the semantic function ⟦.⟧m:c × ℘(s×i×t)→℘(s×i×t) that takes a command c and a status ρ and returns the status ρ affected by c. in order to optimize the memory heap, ρ is populated following a lazy approach, according to which a new entry for the key (s, i, t) is created when the first tagging or untagging action with respect to the tag (i, t) is performed in the scope of s. when the user adds or removes a tag (i, t) for the first time in the session s (case ρ(s, i, t)= ⊥), the value of the entry ρ(s, i, t) is initialized to the docset relative to the query i = t: ds = getdocset(⟦query((i=t),null)⟧solr i the function init(ρ, s, i, t) returns such new ρ over which the tag or untag action is eventually executed. if the action involves a tag (i, t) for which an entry ρ(s, i, t)= ds exists (case ρ(s, i, t) ≠ ⊥), the commands return the new ρ obtained by adding or removing the docset getdocset(rs) to or from ds. such actions are performed in memory with minimal execution time. information technology and libraries | september 2014 32

ρ(s, i, t) ∖ getdocset(rs)] table 5. semantics of tag/untag commands. queries over a virtual information space as mentioned above, the command virtquery(q, s) is implemented by executing the low-level method searchondocset(q', ds). informally, 𝑞′ is the subpart of q whose predicates are not affected by actions in s, while ds is the subset of objects matching tag predicates affected by actions in s, to be calculated by means of the map ρ. to make this a real statement, two main issues must be addressed. the first one is syntactical: how to extract from q the sub-query q' and the subquery to be filtered by ρ to generate ds. the second issue is semantic: the misalignment between the objects in the original information space i, where searchondocset is executed, and the ones in i(s), to be virtually queried over and returned by virtquery. syntactic issue: to obtain 𝑞′ and ds from q, the tagtick virtualizer module includes a query rewriter module that is in charge of rewriting q as a query: q' and qtags in session (1) both queries are compliant to the query grammar in table 1, but the second is a query that groups all tag predicates in q which are affected by s. the reason of this restriction is due to the fact that the method searchondocset(q’, ds) performs an intersection between the docset ds and the docset obtained from the execution of q�. in principle, qtags in session may contain arbitrary combinations of tag predicates (i = t) combined with and and or operators. to get a better understanding, refer to the examples in table 6, where we assumed to have two tag interpretations a with terms {a1, a2} and b with terms {b1, b2} where ρ(s, a, a1) and ρ(s, b, b1) are defined in ρ; note that keyword searches, e.g., “napoleon,” are not run over tag values. the first two queries can be executed, while the last one is invalid. indeed there is no way to factor out the tag predicate (a = a1) so that it can be separated and joint with the rest of the query using an and operator. high-performance annotation tagging over solr full-text indexes | artini et al 33 clearly, the ability of the query rewriter module to rewrite the query independently of its complexity may be crucial to increase the usability level of tagtick virtualizer. in its current implementation, the tagtick virtualizer assumes that q is provided to virtquery as already satisfying the expected query structure (1). as we shall see in the next section, this assumption is very reasonable in the realization of our annotation tagging tool tagtick and, more generally, in the definition of tools for annotation tagging. indeed, such tools typically allow data curators to run google-like free-keyword queries to be refined by a set of tags selected from a list. such queries fall in our assumption and also match the average requirements of this application domain. 𝑞 = "napoleon" 𝐴𝑛𝑑 (𝐴 = 𝑎1 𝑂𝑟 𝐵 = 𝑏1) 𝑤ℎ𝑒𝑟𝑒: 𝑞′ = "napoleon" 𝑞𝑡𝑎𝑔 𝑖𝑛 𝑠𝑒𝑠𝑠𝑖𝑜𝑛 = (𝐴 = 𝑎1 𝑂𝑟 𝐵 = 𝑏1) 𝑞 = (𝐴 = 𝑎2 𝑂𝑟

searchondocset(q�, ds) does not match the expected semantics of virtquery(q, s). the reason is that searchondocset is executed over the original information space i and objects in the returned result set may not reflect the new tagging imposed by actions in s. for example, consider an untagging action for the tag (i, t) and the result set rs in s. although the objects in rs would never be returned for a query virtquery((i = t),s), they could be returned for queries regarding other properties and in this case they would still display the tag (i, t). to solve this problem, the function patchresultset : rs → rs in table 7 intercepts the result set returned by searchondocset and “patches” its objects, by properly removing or adding tags according to the actions in s. to this aim, the function exploits the low-level function intersectsize, which efficiently computes and returns the size of the intersection between two docsets. for each object d in a given result set rs, the function verifies if d belongs to the docsets ρ(s, i, t) relative to the tags touched by the session s: if this is the case (intersectsize returns 1), the object should be enriched with the tag (add(d, (i, t))), otherwise the tag should be removed from the object (remove(d, (i, t))). information technology and libraries | september 2014 34    = = = = ≠ 0 ))(},({ )),(,( 1 ))(},({ )),(,(

tagtick virtualizer implements also patching of results for browse queries. a solr browse query is a cql query q followed by the list of object properties l for which a group-by operation (in the sense of relational databases) is demanded. the query returns two responses: the query result set rs and the group-by statistics (l, v, k(l, v)) calculated over the result set and for the given properties, where k(l, v) is the number of objects featuring the value v for the property l in rs. as in the case of standard queries, the semantic issue affects browse queries when a group-by is applied over a tag interpretation i touched in the current work session. indeed, the relative stats would be calculated over the information space i rather than the intended i(s). to solve this issue, when a browse query demands for stats over a tag interpretation i, the relative triples (i, t, k(i, t)) are patched as follows: 1. if (i, t, k(i, t)) is such that ρ(s, i, t )= ⊥, i.e. the tag was not affected by the session, then k(i, t) is left unchanged; 2. if (i, t, k(i, t)) is such that ρ(s, i, t )= ds, then k(i,t)= intersectsize(ds, getdocset(rs)) the operation returns the number of objects currently tagged with (i, t) which are also present in the result set rs. query execution: the implementation of virtquery can therefore be defined as ⟦virtquery(q,s)⟧tv = patchresultset(searchondocset(q�, ds), ρ, s) where q is rewritten in terms of q� and qtags in session by the query rewriter module, and ds is the docset obtained by applying the function ⟦.⟧vt:q × s × ℘(s × i × t) →ds defined in table 8 to qtags in session. the function, given a query of tag predicates, a session identifier, and the status map ρ returns the docset of objects satisfying the query in the session’s scope. high-performance annotation tagging over solr full-text indexes | artini et al 35 ⟦𝑞1 𝑂𝑟 𝑞2⟧𝑉(𝑠,𝜌) = unifydocsets(⟦𝑞1⟧𝑉(𝑠,𝜌), ⟦𝑞2⟧𝑉(𝑠,𝜌)) ⟦𝑞1 𝐴𝑛𝑑 𝑞2⟧𝑉(𝑠,𝜌) =

action and virtquery, the definition of searchondocset, and the function ⟦.⟧v guarantee the validity of the following claim, crucial for the correctness of the tagtick virtualizer: claim (search correctness) given an information space i, a map ρ, and a session s, for any query q such that 1. q = q� and qtags in session 2. ds = �qtags in session�v(s, ρ) we can claim that ⟦virtquery(q, s)⟧tv = ⟦query(q, null)⟧solr i(s) hence the implementation of the command virtquery matches its expected semantics. making a virtual information space persistent the commitsession(s) command is responsible for updating the initial information space i to the changes applied in s, i.e. add and remove tags to objects in i according to the actions in s. to this aim, the module relies on the map ρ, which associates each tag (i, t) to the set of objects virtually tagged by (i, t) in s, and on the low-level function andnotdocsets. by properly matching the set of objects tagged by (i, t) in i and i(s) the function derives the sets of objects to tag and untag in i. overall, the execution of commitsession(s) consists in: 1. identifying the set of tags affected by tagging or untagging actions in the session s: changedtags(s) = {(i, t)|ρ(s, i, t) ≠ ⊥} 2. for each (i, t) ∈ changedtags(s) a) fetching the result set relative to all objects in i with tag (i = t): rs = query((i = t), null); b) keeping in memory the relative docset ds = getdocset(rs); c) calculating in memory the set of objects in i to be untagged by (i = t): information technology and libraries | september 2014 36 tobeuntagged =

in the two sets; and f) remove session s. the tagtick virtualizer module is also responsible for the management of conflicts on commits and to avoid index inconsistencies. to this aim, only the first commit action is executed, and once the relative actions are materialized into the index, all other sessions are invalidated, i.e., deleted. tagtick user interface: annotation tagging for solr the tagtick user interface module implements the functionalities presented in previously over a solr index equipped with the tagtick virtualizer module described in the section on solr and annotation tagging (see figure 2). the user interface offers to authenticated data curators an annotation tagging environment where they can open work sessions, do and undo sequences of (un)tagging actions, and eventually commit the session into the current solr information space. when data curators log out from the tool, the modules stores on disk their pending work sessions and the relative (un)tagging actions. such sessions will be restored at the next access to the interface, to allow data curators continuing their work. figure 2. tagtick: user interface. the tagtick user interface is a general-purpose module that can be configured to adapt to the classes and to the structure of objects residing in the index. to this aim, the modules acquires this information from xml configuration files where data curators can specify: high-performance annotation tagging over solr full-text indexes | artini et al 37 1. the names of the different classes, the values used to encode such classes in the index, and the index field used to contain such values; 2. the list of tag interpretations together with the relative ontologies: in the current implementation ontologies are flat sets of terms, which can be optionally populated by curators during the tagging step; and 3. the intended use of interpretations: the association between classes and interpretations. once instantiated, the tagtick user interface allows users to search for objects of all classes by means of free keywords and to refine such searches by class and by the tags relative to such class. this combination of predicates, which matches the query structure 𝑞� = 𝑞 𝐴𝑛𝑑 𝑞𝑡𝑎𝑔𝑠 𝑖𝑛 𝑠𝑒𝑠𝑠𝑖𝑜𝑛 expected by the tagtick virtualizer, is then executed by the module and the results presented in the interface. users can then add or remove tags to the objects—the interface makes sure that the right interpretations are used for the given class. as an example, we shall consider the real-case instantiation of tagtick in the context of the hope project, whose aim is to deliver a data infrastructure capable of aggregating metadata records describing multimedia objects relative to labour history and located across several data sources.24 such objects are collected, cleaned, and enriched to form an information space stored into a solr index. the index stores two main classes of objects: descriptive units and digital resources. descriptive unit objects contain properties describing cultural heritage objects (e.g., a pin). digital resource objects instead describe the digital material representing the cultural heritage objects (e.g., the pictures of a pin). tagtick is currently used in the project hope to classify the aggregated objects according to two tag interpretations: “historical themes,” to tag descriptive units with an ontology of terms describing historical periods, and “export mode,” to tag digital resources with an ontology which describes the different social sites (e.g., youtube, facebook, flickr) from which the resource must be made available from. in particular, figure 3 illustrates the hope tagtick user interface. in the screenshot, a set of descriptive units obtained by a query is being added a new tag “communism . . .” of the tag interpretation “historical themes.” the tagtick user interface offers the possibility to access the history of actions, in order to visualize their sequence, and possibly to undo their effects. figure 4 shows the history of actions that led to the actual tag virtualization in the current work session. curators can only rollback the last action they accomplished. this is because virtual tagging actions may be depending on each other; e.g., an action is based on a query that includes tag predicates whose tag has been affected by previous actions. other approaches may infer the interdependencies between the queries behind the tagging actions and expose dependency-based undo options. information technology and libraries | september 2014 38 figure 3. tagtick user interface: bulk tagging action. figure 4. tagtick user interface: managing history of actions. stress tests the motivations behind the realization of tagtick are to be found in annotation tagging requirements of bulk and real-time tagging. in general, the indexing speed of solr highly depends on the underlying hardware, on the number of threads used for feeding, on the average size of the objects and their property values, and on the kind of text analysis to be adopted.25 however, even assuming the most convenient scenario, bulk indexing in solr is comparably slow with respect to other technologies, such as relational databases,26 and far from being real-time. in this section, we present the result of stress tests conceived to provide concrete measures of query performance, i.e., the real-time effect, the scalability of the tool, and how many tagging actions can be handled in the same session. the idea of the tests is to re-create worst scenarios and give evidence of the ability of tagtick to cope and scale with response time and memory high-performance annotation tagging over solr full-text indexes | artini et al 39 consumption. the experiments were run on a machine with processor intel(r) xeon(r) cpu e5630 @ 2.53ghz (4 cores), a total of memory 4 gb, and available disk of 100 gb (used at around 52 percent). the machine installs an ubuntu 10.04.2 lts operating system, with a java virtual machine configured as -xmx1800m -xx:maxpermsize = 512m. in simpler terms, a medium-low server for a production index. the index was fed with 10 million objects randomly generated and with the following structure: [ identifier: string, title: string, description: string, publisher: string, url: string, creator: string, date: date, country: string, subject: terms] the tag interpretation subject can be assigned values from an ontology terms of scientific subjects, such as “agricultural biotechnology,” “automation,” “biofuels,” “biotechnology,” “business aspects.” the objects are initially generated without tags. each test defines a new session s with k tagging actions of the form action(tag, virtquery(identifier <> id,null), t, s) where id is a random identifier and t is a random tag (subject, term). in practice, the action adds the tag t to all objects in the index, thereby generating docsets of size 10 million. once the k actions are executed, the test returns the following measures: 1. the size of the heap space required to store k tags in memory. 2. the minimal, average, and maximum time required to reply to two kinds of stress queries to the index (calculated out of 100 queries): a. the query identifier <> id and(i,t)∈s(i = t): the query returns the objects in the index which feature all tags touched by the session. b. the query identifier <>id or(i,t)∈s(i = t): the query returns the objects in the index which feature at least one of the tags assigned in the session. in both cases, since tagging actions where applied to all objects in the index, the result will contain the full index. however, in one case the response will be calculated by intersecting docsets, while in the other case by unifying them. note that by selecting a random identifier value (id), the test makes sure that low-level solr optimization by caching is not fired, as this would compromise the validity of the test. information technology and libraries | september 2014 40 3. the minimal, average, and maximum time required to reply to browse queries which involve all tags used in the session (calculated out of 100 queries). 4. the time required to reconstruct the session in memory whenever the data curator logs into tagtick. the results presented in figure 5 show that the average time for the execution of search and browse queries always remain under 2 seconds, which we can consider under the “real-time” threshold from the point of view of the users. user tests have been conducted in the context of the hope project, where curators were positively impressed by the tool. hope curators can today apply sequences of tagging operations over millions of aggregated records by means of a few clicks. moreover, independently of the number of tagging operations, queries over the tagged records take about 2 seconds to complete. the execution time has a major increase from 0 tags to 1 tag. this behavior is expected because when there is 1 tag in the session, the 10 million records must be “patched.” from 1 tag onwards the execution time increases as well, but not at the same rate as in the previous case. this means that in the average case patching 10 million records with 100 tags does not cost much more than tagging them with 1 tag. figure 5. stress test for tagtick search and browse functionality. the results in figure 6 show that the amount of memory to be used does not exceed the limits expected on reasonable servers running a production system. the time required to reconstruct the sessions is generally long, starting from 20 seconds for 50 tags up to 1.5 minutes for 200 tags. high-performance annotation tagging over solr full-text indexes | artini et al 41 on the other hand, this is a one-time operation, required only when logging in to the tool. figure 6. stress test for heap size growth and session restore time. conclusions in this paper, we presented tagtick, a tool devised to enable annotation tagging functionalities over solr instances. the tool allows a data curator to safely apply and test bulk tagging and untagging actions over the index in almost real time and without compromising the activities of end users searching the index at the same time. this is possible thanks to the tagtick virtualizer module, which implements a layer over solr that enables real-time and virtual tagging by keeping in memory the inverted list of objects associated to a (un)tagging action. the layer is capable of parsing user queries to intercept the usage of tags kept in memory and, in this case, to manipulate the query response to deliver the set of objects expected after tagging. future developments may regard the ability to enable more complex query parsing to handle rewriting of a larger set of queries beyond google-like queries currently handled by the tool. another interesting challenge is tag propagation. curators may be interested in having the action of (un)tagging an object to be propagated to objects that are somehow related with the object. handling this problem requires the inclusion into the information space model of relationships between classes of objects and the extension of the tagtick virtualizer module for the specification and management of propagation policies. acknowledgements the work presented in this paper has been

sharding techniques with parallel feeding. 26. whyusesolr—solr wiki, http://wiki.apache.org/solr/whyusesolr. methods of randomization of large files with high volatility 79 patrick c. mitchell: senior programmer, washington state university, pullman, washington, and thomas k. burgess: project manager, institute of library research, university of california, los angeles, california key-to-address conversion algorithms which have been used for a large, direct access file are compared with respect to record density and access time. cumulative distribution functions are plotted to demonstrate the distribution of addresses generated by each method. the long-standing practice of counting address collisions is shown to be less valuable in fudging algorithm effectiveness than considering the maximum number of contiguously occupied file locations. the random access disk file used by the washington state university library acquisition sub-system is a large file with a sizable number of records being added and deleted daily. this file represents not only materials on order by the acquisitions section, but all materials which are in process within the technical services area of the library. the size of the file currently varies from approximately 12,000 to 15,000 items and has a capacity of 18,000 items. over 40,000 items are added and purged annually. each record consists of both fixed length fields and variable length fields. fixed fields primarily contain quantity and accounting information; the variable length fields represent bibliographic data. records are blocked at 1,000 characters for file structuring purposes; however the variable length information is treated as strings of characters with delimiters. the key to the file is a 16-character structure which is developed from the purchase order number. the structure of the key is as follows: six digits of the original purchase order number, two digits of partial order and credit information, and eight digits containing the computed relative record address. proper development of this key turns out to be 80 journal of library automation vol 3/1 march, 1970 the most important factor in achieving efficiency in both file access time and record density within the file. the w.s.u. purchase order numbering system, developed from a basic six-digit purchase order number, allows up to one million entries. of these, the library currently uses four blocks: one block for standing orders, one block for orders originating from the university after the system becomes operational, another block used by the systems people in prototype testing of the system, and a fourth block which was given to one vendor who operates an approval book program. in mapping a possible million numbers into eighteen thousand disk locations, there is a high probability that the disk addresses for more than one record will be the same. disk location, also called disk address, home position, and relative record address ( rra) in this paper, refers to the computed offset address of a record in the file, relative to the starting address of the file. currently, the file resides on an ibm 2316 disk pack which can store six 1000-character records per track. thus if the starting address of the file is track 40, a record with rra = 5 would have its home position on track 40, while a record with rra = 6 would have its home position on track 41. it should be noted that routines in this system are required to calculate neither absolute track address nor relative track address and therefore the file could be moved to any direct access device supported by os/bdam without program modification. when two records map into the same address, it is called a collision. for a write statement under the ibm 360 operating system, basic direct access methods, the system locates that disk address generated and if another record is found there, it sequentially searches from that point forward until a vacant space is found and then stores the new record in that space. the sequential search is done by a hardware program in the i/ 0 channel and proceeds at the rotational speed of the device on which the file resides. the cpu is free during this period to service other users. similarily, when searching for a record, the system locates the disk address and matches keys; if they do not match, it sequentially searches forward from that point. long sequential searches sharply degrade the operating efficiency of on-line systems. in initial experimentation with this file, it was discovered that some records were 2,500 disk positions away from their computed locations. this seriously reduced response time to the terminals which were operating against those records. the necessity to develop a method for placing each record close to its calculated location became quite obvious. however, the methodology for doing this was not as clear. the upper bound delay for a direct access read/write operation can be defined as the largest number of contiguously occupied record locations within the file. the problem of minimizing this upper bound for a particular file is equivalent to finding an algorithm which maps the keys in such a way that unoccupied locations are interspersed throughout the randomization of large files/mitchell and burgess 81 file space. one method for doing this is to triple the amount of space required for the file. this has been a traditional approach but is unsatisfactory in terms of its efficiency in space utilization. the method first used by the library was motivated by the necessity to "get on the air." its requirements were that it be easily implemented and perform to a reasonable degree. the prime modulo scheme seemed to qualify and was selected. as this algorithm was used, the largest prime number within the file size was divided into the purchase order number and the modulo remainder was used as an address; that is, rra = [po modulo pr] where rra is the relative record address, po is the purchase order number, and pr is a prime number. during the initial period file size grew to about 8,000 records. because the acquisitions section was converting from its manual operation, the file continued to grow in size and the collision problem became pronounced. when the file reached about 70% capacity-that is when 70% of the space allocated for the file was being occupied by records-this method became unusable; records were then located so far from their original addresses that terminal response times became degraded and batch process routines began to have significant increases in run times. with no additional space available to expand the size of the file, it became necessary to increase the record density within the existing file bounds. therefore an adaptation of the original algorithm was developed. in addition to generating the original number by dividing a prime number into the purchase order number and keeping the modulo remainder, the purchase order number was multiplied by 300 and divided by that same prime number to get an additional modulo remainder; the latter was added to the first modulo remainder and the sum then divided by 2: (po modulo pr) + (300 • po modulo pr) 2 rra = again this scheme brought some relief, but the file continued to grow as the system was implemented, and it became obvious that this procedure would also fail because of over-crowded areas in the file. a search of the literature using w. b. climenson's chapter on file structure ( 2) as a start provided some other methods for reducing the collision problem ( 1, 3, 4, 5, 6). several randomization or hashing schemes were examined. however, none of these methods appeared to be particularly pertinent to the set of conditions at washington state. in order to bring relief from the continuing problem of file and program maintenance involved with changing the file-mapping algorithm, research was initiated to devise an algorithm which would, independent of the input data, map records uniformly across the available file space. the algorithm which resulted utilizes a pseudo-random number generator, rand (7) developed at the w.s.u. computing center randl, program 360l-13.5.004, computing center library, computing center, 82 journal of library automation vol 3/ 1 march, 1970 washington state university, pullman, washington. the normal use of rand is to generate a sequence of uniformly distributed integers over the interval [1, m], where m is a specified upper bound in the interval [1, 231 -1]. in addition to m, rand has a second input parameter: n, which is the last number generated by rand. given m and n, rand generates a result r. rand is used by the algorithm to generate relative disk addresses by setting m to the size or capacity of the file, by setting n to the purchase order number of the record to be located, and by using r as the relative address of the record. rra =rand (po, m ) . in order to test the effectiveness of this algorithm and others which might be devised, a file simulation program was written bdamsim, program 360l-06.7.008, computing center library, computing center, washington state university, pullman, washington. inputs to this program are: a) an algorithm to generate relative record locations; b) a sequential file which contains the input data for "a"; c) various scalar values such as file capacity, approximate number of records in the file, title of output, etc. the program analyzes the numbers generated by "a" operating on "b" within the constraints of "c". the outputs of the program are some statistical results and a graphical plot showing the cumulative distribution function of the generated addresses. figures 1, 2, and 3 show the plotted output of the three algorithms operating against the current acquisitions file. the abscissas of the plots 8 • )!! ii! li 1i :;! 5i ::! !':! ~ ~ n n ~~ a= .. ~, ,~ -' -' ~)11 i'! a; ·:5 ~li ma! 0.. 0.. .. .. it ,:: ~ ~

generating disk addresses less than or equal to addresses on the abscissas. the ideal algorithm will uniformly distribute the records throughout the file and its plot will be a straight line from the lower left comer of the plot to the upper right comer. the density of the file is represented by the slope of the plot. a steep (vertical) slope represents many records clustered together; a mild (horizontal) slope represents a less densely populated area; a slope of 1 represents a uniform distribution. in table 1 the three mapping methods are compared with respect to the number of collisions and the upper-bound read/write delay. these statistics are based on the current acquisitions file at 90% capacity ( 12,913 records and 14,347 locations) . looking at only the collision statistics, it would appear that method i, rra =[po mod pr], would provide the best mapping. however, its upper-bound read/ write delay indicates that one area of 8,823 locations is contiguously occupied. any new record to be inserted near the beginning of this area would necessarily be stored over 8,800 locations away from its computed address. method ii would be a less effective algorithm for use with the current acquisitions file, as it has a larger (11,585) upper bound read/ write delay than method i and has fewer records in their home positions. when method ii was implemented, it represented an improvement over method i. since that time, the data base contents have changed and so have the comparative performance statistics of the methods. this illustrates the dependence of the effectiveness of these methods upon the data base itself. the statistics for method iii, rra= [rand (po, pr)], indicate that more records are located a short distance from their computed addresses than in method i. however, no record is more than 338 locations away. table 1. comparison of three mapping methods rra percent of records having 0-6 collisions upper bound read/ write delay 0 1 2 3 4 5 6 i po mod pr

assigns home positions ~ 2, 4, 3, 4, 3, 2} to the records and rra generator b assigns home positions of ~ 0, 4, 0, 4, 4, 0~. if e denotes an empty, or non-occupied position in the file, the corresponding file maps would actually appear as: 0 1 2 3 4 5 6 7 a ie ie 1213141413121 bioioioiei41414iei on the basis of table 1, and with x representing the number of collisions, the statistics would be as follows: x= 1 x=2 ubrwd a i 100 6 i b ,__i __ __..!. __ 100 _ __,__ __ 3_----'1 while method a provides fewer collisions, it has saturated one area of the file space, indicated by the high ubrwd. method b provides a superior mapping in that file saturation has been minimized. the acquisitions file is contained on an ibm 2316 disk pack. it has been found that a read/write delay of 200 locations is about equivalent to one second. hence method i represents a maximum delay of 44 seconds, method ii a maximum delay of 58 seconds, and method iii a maximum delay of 2 seconds. the library systems group, together with the library staff, have arbitrarily set the maximum delay for terminal response time at 23~ seconds. utilizing methods i or ii, this limit was reached when the file was 60-80% full. with method iii, the limit is not reached until the file is 90-95% full. from these data it can be seen that the method utilizing the random number generator is clearly an improvement over the other methods tested. this simulation has been performed against the acquisitions file at regular intervals to see if it would continue to be uniformly populated. it has been found that even under highly volatile conditions, the records in the file remain uniformly distributed throughout the available file space. references 1. burgess, t. k.; ames, j. l.: lola, library on-line acquisition

payne: systems development librarian, and robert s. mcgee: assistant systems development librarian; university of chicago library, chicago, illinois 115 a comparison of arrival dates of 5020 lc proofslips and corresponding marc magnetic tape records reveals that four-fifths of the marc records were received the same week as, or earlier than, the proofslips. the purpose of this study is to determine the timeliness of marc ii records' arrival dates in comparison to the arrival dates of matching lc proofslips. the acquisitions department of the university of chicago library receives a complete set of cut and punched lc proofsheets (or "lc proofslips") that is used primarily for selection and ordering. in examining potential uses of marc records in acquisitions processing, the library systems development office felt that a critical determinant would be the timeliness of marc records in comparison to the arrival dates of the matching lc proofslips. accordingly, the study described below was designed to gather data upon which appropriate system design questions might be considered. it was decided that "arrival date" would be defined as the week in which an arrival occmted, since the initial processing and distribution of incoming lc proofslips is framed within weekly, rather than daily, periods. "week" was defined as the monday through friday workweek. "arrivals" were defined as deliveries of marc tapes and lc proofslips by the library mail service. no attempt was made to influence the normal delivery procedures, or to specialize or hasten identification of these 116 journal of library automation vol. 3/2 june, 1970 materials for priority handling. arrival weeks were numbered consecutively, the week of march 31 april 4, 1969, being designated week 1. marc tape numbers correspond to arrival week numbers; i.e., marc tape #4 arrived during week 4. table 1 presents these correspondences. table 1. week numbers for 15 weeks of study

subsequent weeks, complete collections of proofslips bearing the marc acronym (marc proofslips) were attempted, so that proofslip data beginning with week 3 (april 14-18) are more complete. proofslip collection was terminated in week 15. discrepancies between the counts of marc records and the numbers of marc proofslips collected have not been accounted for, but possible reasons are discussed in the following section. data collection was based upon comparisons of: 1) the weekly printed indexes, in lc card number order, that came with marc ii tapes; and 2) weekly lists of marc proofslip arrivals. in each incoming batch of lc proofslips, those with marc notes were separated and their arrival date noted. the marc proofslips for each week were put in primary order by the £rst two digits (series number) of the card number, and were secondarily ordered within each series by the serial number following the hyphen, thereby matching the order of lc card numbers in the marc indexes. these numbers were transcribed to create a weekly list of proofslip arrivals. two new lists of lc card numbers were derived each week: 1) a marc index; and 2) a proofslip list. weekly each new list was compared with all lists of the other type to identify card number matches. \ proofslip and marc arrival dates/payne and mcgee 117 thus, each of the two types of lists was cross-tabulated with all the lists of the other type, showing on all lists which card numbers had been matched, and the week numbers of these matches. counts were made of the matches tabulated on each list, and were entered into table 2. matches made during a given week are subcounted by series groups 65-68, 69, and the 7 series. the cumulative percentages of marc record and proofslips matches were entered into tables 3 and 4. table 3 contains the percentages of matches for any week's proofslips with successive marc tapes. for example, of the 340 proofslips received in week 4, 71.2% matched marc records received the same week, or earlier, i.e., tapes 4, 3, and 2. table 4 contains the percentage of matches for any marc index on successive proofslip lists. for example, of the 768 records on marc tape number 5 (received in week 5) 23% were matched by proofslips received the same week, or earlier, i.e., weeks 5, 4, 3, and 2. analysis of results some patterns of marc and proofslip arrivals are indicated by the tables. the results in table 2 show that there is not a one-for-one weekly relationship between proofslip and marc record arrivals. for example, the 340 marc proofslips received in week 4 matched tape records received from week 2 through week 10, although the highest number of matches was also in the tape received in week 4. in later proofslip weeks, however, the highest number of proofslip matches was with tape records received at least one week earlier. a summary of table 2 would show that of the 5020 marc proofslips received during weeks 3-10, 4004, or 79.8% were matched to marc records received the same week or earlier. in table 3, the cumulative percentages of proofslip matches with successive marc indexes indicate, for several of the weeks, more than a 90% match with tape records two weeks after proofslip arrivals. table 3 shows that the percentage of matches for a set of proofslips received in one week with the marc indexes received the same week or earlier ranges from 48.9% to 91.6%. table 4 shows that the percentage of matches for a marc tape received in a given week with the proofslips received the same week or earlier ranges from 7.1% to 49.8%. for the period of weeks corresponding to tape numbers 3-10, 6335 tape records (from table 4) and 5020 proofslips (from table 2 or 3) were received. the reason for the discrepancy between the number of marc records and the number of marc proofslips is not clear, but is possibly due to the combined effects of basic factors such as the limited period of the study, the difficulties of collecting proofslips in a working environment, and the nature of the manual effort required to list lc card numbers and compare proofslip lists and marc indexes. table 2. number of proofslip matches with marc indexes by arrival week

lita’s past and future aimee fifarek information technologies and libraries | september 2016 3 when i reached out to ital editor bob gerrity about my first president’s column, he graciously provided copies of past lita presidents’ columns to get me started. it reminded me once again of the illustrious company i am in, starting with stephen r. salmon, the first president of the information services and automation division, as we were known until 1977. i am proud to be at the head of lita as it begins to celebrate its 50th anniversary year. a half century ago when lita was founded the world was experiencing an era of profound technological change. the us and soviet union were battling to be first in the space race, and an increasing number of world powers were engaging in nuclear testing. while civil rights demonstrations and the fighting in vietnam dominated the news, we were imagining peace via the technologically-driven future depicted in a new tv series called star trek. with tv focused on the stars, we were able to go to the movies and explore the strange new world of inner space in fantastic voyage. technology was poised to enter our daily lives as well, with diebold demonstrating the first atm1 and ralph h. baer writing the 4-page paper that would lay the foundation for the video game industry.2 heady times for technology indeed, and the fact that libraries were sufficiently advanced to require an association dedicated to supporting technologists is hardly surprising. by the time of lita’s founding at the 1966 midwinter meeting in chicago, library automation had been in development for over a decade.3 marc was just being invented, with the first tapes from the library of congress scheduled to go to the sixteen pilot libraries later that year. membership in the only organization that existed, the committee on library automation (cola), was restricted to the handful of professionals who either developed or managed existing library systems. but technology was beginning to impact many more librarians than just those rarified few. according to president salmon, “it was clear that large numbers of librarians who didn't meet cola's standards for membership were in need of information on library automation and wanted leadership.”4 the first meeting of our division on july 14, 1966 at the ala annual conference in new york was attended by several hundred librarians interested in information sharing, technology standards, and technology training for library staff. this group created the first mission, vision, and bylaws that set us on a 50-year path of success. lita is well positioned to take the first steps into our next 50 years. thanks to the efforts of last year’s lita board, we are on the verge of adopting a new two-year strategic plan that is designed aimee fifarek (aimee.fifarek@phoenix.gov) is lita president 2016-17 and deputy director for customer support, it and digital initiatives at phoenix public library, phoenix, az. president’s message | fifarek doi: 10.6017/ital.v35i3.9526 4 to guide us through the current transitional period. it will be accompanied by a tactical plan that will allow us to document our accomplishments and set the stage for an ongoing culture of continuous planning. also, jenny levine has proven to be extremely capable as she completes her first year as lita executive director. she has just the right combination of ala experience, technology know-how, and calm competence to guide us through the retooling and reimagining that is required to take a middle-aged association into the next phase of its life. the four areas of focus in the new strategic plan will help us to balance our efforts between preserving the strengths of our past and adapting our organization for a successful future. the first area of focus, member engagement, shows that our primary commitment needs to be to lita members. without you, lita would not exist. one of the key efforts is to increase the value of lita for members who are unable to travel to conferences. with travel budgets down and staying low, online member engagement is an area all of ala needs to improve, and who better to lead in this area than lita. the next area, organizational sustainability, is all about keeping the infrastructure of the organization strong, much of which happens in the domain of lita staff. budgeting, quality communication, and strategic planning all live here. the section on education and professional development recognizes the important role that webinars, online courses, online journal, and print publications play in allowing lita members to share their knowledge on both cutting edge and practical topics with the rest of the association and ala in general. we are already doing great work here and we need to better support and expand these efforts. the last focus area, advocacy and information policy, represents a future growth area for lita. now that everyone in the library world "does" technology to a certain extent, lita needs to think about how we will differentiate ourselves as outside competencies increase. our advantage is that we have been doing and thinking about technology for much longer than anyone else. with our vast wealth of experience, it's appropriate that we work to become thought leaders and implementers in the information policy realm. in this, as always, we return to where we started: our members. lita has thrived over the last 50 years because of this, our most important resource. lita was founded on the concept of sharing information about technology through conversation, publications, and knowledge creation. we endure because you, the committed, passionate information professionals are willing to share what you know with those who come after. and like our founders, there are always individuals who are willing to take on the mantle of leadership, whether through getting elected to lita board, becoming a committee or interest group chair, serving in key editorial roles for our monographs, journal, and blog, or joining the all-important lita staff. thanks to all of you who make lita’s future happen every day. i am proud to be in your company. information technologies and libraries | september 1016 5 references 1 . alan taylor, “50 years ago: a look back at 1966,” the atlantic photo, march 23, 2016,

an academic library mia massicotte and kathleen botter information technology and libraries | march 2017 11 abstract this study examines etds deposited during the period 2011-2015 in an institutional repository, to determine the degree to which the documents suffer from reference rot, that is, linkrot plus content drift. the authors converted and examined 664 doctoral dissertations in total, extracting 11,437 links, finding overall that 77% of links were active, and 23% exhibited linkrot. a stratified random sample of 49 etds was performed which produced 990 active links, which were then checked for content drift based on mementos found in the wayback machine. mementos were found for 77% of links, and approximately half of these, 492 of 990, exhibited content drift. the results serve to emphasize not only the necessity of broader awareness of this problem, but also to stimulate action on the preservation front. introduction a significant proportion of material in institutional repositories is comprised of electronic theses and dissertations (etds), providing academic librarians with a rich testbed for deepening our understanding of new paradigms in scholarly publishing and their implications for long-term digital preservation. while academic libraries have long collected and preserved hard copy theses and dissertations of the parent institution, the shift to mandatory electronic deposit of this material has conferred new obligations and curatorial functions not previously incorporated into library workflows. by highlighting etds as a susceptible collection deserving of specific preservation actions, we draw attention to some unique responsibilities for libraries housing university-produced content, particularly as scholarly information continues its shift away from commercial production and distribution channels. as teper and kraemer point out in their discussion of etd program goals, “without preservation, long-term access is impossible; without long-term access, preservation is meaningless.”1 what is reference rot, and why study it? in addition to linkrot (where a link sends the user to a webpage which is no longer available), mia massicotte (mia.massicotte@concordia.ca) is systems librarian, concordia university library, montreal, quebec, canada. kathleen botter (kathleen.botter@concordia.ca) is systems librarian, concordia university library, montreal, quebec, canada. a case study of electronic theses and dissertations (etds) in an academic library | massicotte and botter | https://doi.org/10.6017/ital.v36i1.9598 12 there are webpages that remain available, but whose contents have undergone change over time- known as content drift. this dual phenomena of linkrot plus content drift has been characterized as reference rot by the hiberlink project team,2 and has important implications for digital preservation. since theses and dissertations are original works born digital by virtue of mandatory deposit programs, a university’s etd program is effectively a digital publishing initiative, accompanied by a new universe of responsibility for its digital preservation. due to the specialized nature of graduate-level research, etds frequently include links to resources on the open web, for example, personal blogs, project websites, and commercial entities. digital object identifiers (dois), useful in the context of published literature, do not apply to urls on the free web, which are doi-indifferent. open web links also fall outside the scope of preservation initiatives such as lockss (lots of copies keep stuff safe)3 which aim to safeguard the published literature. with increasing frequency, researchers are citing newer forms of scholarship, which do not readily fall under the rubric of published literature. moreover, since thesis preparation is conducted over a period of time typically measured in years, links cited therein are likely to be more vulnerable to linkrot and content drift by the time of manuscript submission. yet despite the surfeit of anecdotal daily evidence that urls vanish and result in dead links, phillips, alemneh, and ayala point out that “by and large academic libraries are not capturing and maintaining collections of web resources that provide context and historical reference points to the modern theses and dissertations held in their collections.”4 since an etd comprises a unique form of scholarly output produced by universities, and simultaneously satisfies the parent institution's degree-granting apparatus, as well as reflecting its academic stature on the international stage, the presence of reference rot in this body of literature is of particular concern and worthy of immediate attention. smoking guns there has been no shortage of evidence reporting on the linkrot phenomena over the last two decades. koehler, whose initial study on linkrot appeared in jasis in 1999, periodically revisited, analyzed, and reported on the same set of 360 urls collected in his original study.5,6,7 in 2015, upon the twenty-year benchmark of the original data collection, oguz and koehler reported in jasis that only 2 of the original links remained active.8 a number of foundational studies, including casserly and bird,9 spinellis,10 sellitto,11 falagas, karveli, and tritsaroli,12 and wagner et al.13 have reported on linkrot occurring in professional literature. sanderson, phillips, and van de sompel provide a table of 17 well-known linkrot studies, comparing overall benchmarks, and supplying a succinct summary of the scope of each study.14 linkrot also gained further important exposure with the harvard law school study by zittrain, albert, and lessig, which found that 70% of 3 harvard law journal references, and 49.9% of urls in supreme court opinions examined, no longer pointed to their originally cited sources.15 information technology and libraries | march 2017 13 members of the hiberlink project, which set out to examine “a vast corpus of online scholarly publication in order to assess what links still work as intended and what web content has been successfully archived using text mining and information extracting tools” have been pivotal in making the case for reference rot.16 hiberlink demonstrated that failure to link to cited sources was due not only to linkrot, but also to web page content which changed over time.17 a new dimension of the digital preservation universe was thrown into sharp relief with follow-up study by klein et al. (2014), which examined one million web references extracted from 3.5 million science, technology, and medicine (stm) articles published in elsevier, pubmed central, and arxiv, between the years 1997 and 2012. the study concluded that one in five articles suffers from reference rot.18 though the study focused on stm articles, its authors drew attention to theses and dissertations as a susceptible class of material. analyzing the same set of links extracted from this large stm corpus, jones et al. (2016) recently reported that 75% of referenced open web pages demonstrated changes in content.19 etds — a susceptible collection the digital preservation part of institutionally mandated etd deposit has yet to have its dots fully connected to the rest of the diagram. after four years of research into academic institutions’ etd programs, halbert, skinner, and schultz reported that close to 75% of respondents surveyed had no preservation plan for their etd collections.20 despite the prevalence of linkrot studies, linkrot in etds has not been subjected to similar scrutiny, and the implications of disappearance of content is underappreciated. while mandatory deposit programs have become relatively commonplace, focus has largely remained on policy and implementation aspects, metadata quality, interoperability and conformance to standards.21,22 there are few studies which focus on institutional repository link content. the study conducted by sanderson, philips, and van de sompel (2011) was a large-scale examination of two repositories.23 400,144 papers deposited in arxiv, and 3,595 papers in the university of north texas (unt) digital library repository were studied, and more than 160,000 urls examined. links were analyzed for persistence and the availability of mementos, that is, whether prior versions of the page existed in a public web archive, such as the internet archive's wayback machine. for 72% of unt urls, either mementos were available, or the resource still existed at its original location, or both. although 54% (9,880) were available in one or more international web archives, 28% (5,073) of unt's etd links were found to no longer exist, nor had they been archived by the international archival community. phillips, alemneh, and ayhala looked at overall general patterns and trends of url references in repository etds, examining 4,335 etds between the years 1999-2012 in the unt repository.24 the team analyzed 26,683 unique urls in 2,713 etds containing one or more links, finding an overall average of 10.58 unique urls per etd with one or more links. the unt team provided a a case study of electronic theses and dissertations (etds) in an academic library | massicotte and botter | https://doi.org/10.6017/ital.v36i1.9598 14 breakdown of domain and subdomain occurrence frequency, and indicated areas of future investigation into content-based url linking patterns of etds. etd link decay was studied by sife and bernard, who performed a citation analysis on urls in 83 theses published between 2007 and 2011 at tanzania's sokoine national agricultural library.25 15,468 citations were examined, 9.6% (1,487) of which were open web citations. urls were considered active if found at the original location, or available after a url redirect. the authors manually tested urls over a period of seven days to record their accessibility, noting down inaccessible urls error messages and domains, and analyzing the types of errors encountered. the authors calculated that it took only 2.5 years for half of the web citations to disappear. at the etd2014 conference,26 an important study of 7,500 etds in 5 u.s. universities was presented. of 6,400 etds defended between 2003 and 2010, approximately 18% of open web link content was confirmed as lost, and a further 34% at risk of loss, that is, live links which lacked an archived copy.27 though the results of that particular study have not been formally published, it was briefly summarized in a session held at the 38th uksg annual conference in glasgow, scotland in march 2015, an account of which was subsequently published by burnhill, mewissen, and wincewicz in insights.28 given the scarcity of published literature on link content as found in etds, this present study which examines reference rot in etds in an academic institutional repository is unique, draws attention to an important digital collection which is vulnerable to loss, and highlights need for action. background and context concordia university is a comprehensive university located in montreal, with a student population of 43,903 full-time equivalents in 2015, of which 7,835 were graduate students. 27 phd programs were offered in 2015,29 and 43 programs at the masters level. faculties of arts and science, engineering and computer science, fine arts, and business have a thesis requirement, and produce upwards of 350 masters and 150 phd dissertations annually. the broad disciplines, and the departmental clusters used in this study are shown in table 1. prior to the thesis deposit mandate, concordia university library housed hard copy versions of theses and dissertations in the collection. in 2009, the library launched spectrum, concordia’s eprints institutional repository, playing a leadership role in spectrum's implementation and policy development, and providing training and support to the school of graduate studies regarding submission and management of theses for deposit. following a successful pilot project, the graduate studies office ceased accepting paper manuscripts, and mandated electronic deposit of all theses and dissertations into spectrum as of spring 2011. information

engineering & computer science methodology we concentrated on phd dissertations (henceforth etds) in spectrum in order to limit the scope of the project; master's theses were excluded. a 5-year period was chosen, beginning with the first semester of mandatory deposit, spring 2011, through fall 2015, a total of 720 etds. since concordia etds are released for publication immediately following convocation, the university's official convocation dates were used to identify the set of documents to be downloaded and examined. we proceeded in phases: first downloading etds from spectrum and converting to a text format that could be examined for patterns; then extracting links from each and testing programmatically a case study of electronic theses and dissertations (etds) in an academic library | massicotte and botter | https://doi.org/10.6017/ital.v36i1.9598 16 for linkrot; then drawing a stratified random sample of active urls and visiting them to determine if content drift had taken place. our methodology for link extraction was similar to those described by klein et al.,30 and zhou, tobin, and grover.31 during the dissertation download stage, 36 etds with embargoed content were encountered and eliminated. etds were then converted from existing pdf/a format to xml. a further 20 documents failed to convert due to nonstandard or complex formatting which resulted in unreadable, garbled characters. these documents resisted multiple conversion attempts, and since they could not be mined, had to be eliminated. a final total of 664 etds were successfully converted using three different tools: 97% (644) were converted using pdftohtml,32 the remaining 3% by either givemetext (14)33 or adobe acrobat (3). a spot check of documents was sufficient evidence that many links occurred throughout the text body. since we intended to extract urls to the open web, we wanted to err on the side of detecting more links, rather than easily-identifiable well-formed urls. links were mined from the body of the text in a manner similar to the study carried out at unt.34 we wanted a regular expression which would catch as many urls as possible, expecting to manually clean the link output before further processing. we tested multiple regular expressions35 against a small sample of our converted etds and compared the results. we selected one which seemed well-suited for our purpose, as it was liberal in detecting links throughout the text, was able to extract links which contained obvious omissions and problems — for example, those that lacked http:// prefixes — but also caught non-obvious errors, such as ellipses in long urls. we considered how deduplication of extracted links might affect the outcome, and opted to count each link as an individual instance. manual cleanup included catching urls that broke across new lines, identifying false hits such as titles containing colons and dois, and adding escape encoding characters for "&" and "%" in order to generate a clean url for use in the next step of the process. methodology — linkrot collection a script programmatically used the curl command line tool to visit each link and fetch the http response code in return.36 an output listing was produced for each doctoral dissertation, comprised of the original urls, the final urls, and the http response codes. link output for each of the converted 664 etds was collected from december 2015 to january 2016, with the fall 2015 semester checked in march 2016. 76% (504 of 664) of etds contained one or more links, the highest number of links (5,946) falling into the arts group. 24% (160 of 664) of etds contained no links. for the 5-year period, the broad discipline breakdown of documents examined, the number of etds with links, and the number of links extracted are shown in table 2. converted etds by publication year, broken out by broad disciplines, are shown in figure 1. information technology and libraries | march 2017 17 discipline number

disciplines. etds which did not contain any links were excluded from the sample. using only documents with one or more active links, a stratified random sample of 10% was drawn for a final sample of 49 etds containing a total of 990 links. a snippet of text surrounding each link was then also extracted from each etd, along with any "date accessed" or "date viewed" information if present. each link was manually visited, assessed for content drift, and observations recorded. the breakdown of the content drift sample is shown in table 4. a case study of electronic theses and dissertations (etds) in an academic library | massicotte and botter | https://doi.org/10.6017/ital.v36i1.9598 20 discipline etds with links etds with active links (2xx) etds sampled for content drift* number of

for content drift analysis * 10% sample drawn from each discipline’s pool of etds; only etds with urls relevant for content drift assessment. visited links were benchmarked against the existence of a memento -an archived snapshot of that page located in the wayback machine.37 since the university sets a strict thesis submission deadline of 3 months prior to convocation, mementos prior to submission deadline would be sought. based on the occurrences of "date accessed" and discursive information found in the snippets, we arrived at the supposition that links were likely to have been checked the closer the student approached final stages of manuscript preparation, although this is not verifiable. we set ourselves a soft window for locating an archived snapshot using a date 6 months prior to the convocation date as the benchmark; that is, for each semester's deadline date, an additional 3 months was added, arriving at a 6-months-prior-to-publication marker. since programmatic analysis of 990 links required time, expertise, and resources not available to us, we approached the problem heuristically. assuming that online consultations are not linear, active links occurring multiple times in a document were given equal weight. each link was manually checked in the wayback machine using "date viewed" if provided; if no date was provided (the majority of cases), wayback was checked to see if an archived version existed as close to our 6 month soft marker as possible. if a memento was not found within a month earlier/later than the soft marker, then the nearest neighboring older memento was selected, if one existed. the original url, the date the url was visited, and whether a snapshot was located in wayback was recorded. all links were checked during july-august 2016. if the initial web browser failed to access, a second and sometimes third browser was tried, using safari, chrome, and internet explorer (ie) in that order. unsuccessful attempts to reach wayback were rechecked in september. the question as to whether, and to what degree content drift had occurred was assessed, and is discussed in the next section. information technology and libraries | march 2017 21 findings and discussion linkrot findings of 664 etds examined for linkrot, 77% of links tested returned an active http response code in the 2xx range -roughly three-quarters overall. numbers of links by broad discipline varied greatly, as shown in figure 2 (healthy links in green, linkrot shown in red). linkrot rates ranged from 21% in fine arts, to 26% in business, as seen in last column of table 3. it should be noted that 2xx response codes are also returned for pages that disguise themselves as active links. for example, a url returns an active status code when a domain has been parked (e.g. purchased to reserve the space), or when a customized 404-page-not-found is encountered. since we had no mechanism in place to treat false positives, these were flagged during the linkrot phase as candidates for subsequent content drift analysis. 23% (2,604 of 11,437) of all links, returned a response code of something other than in the 2xx-range and considered linkrot -roughly one-quarter. response codes in the 4xx range alone, including 404-page-not-found errors, comprised 17% (1,916 of 11,437) of all links. table 5 shows the breakdown of the total number of links that were visited in the spring of 2016 for linkrot determination. http response code category meaning of http response code* number of links percent of total links (%) 0

redirects http responses ranged from a high of 85% active in 2015, to a low of 69% active in 2011, the oldest publication year. to put it differently, the most recent year exhibited a linkrot rate of 15%. consistent with other studies, linkrot manifests itself quickly after publication and increases over time, as indicated by percentages shown in figure 2. content drift findings of the 990 links visited to check for the presence of content drift, 764 (400 + 364), or 77%, had a wayback memento compared 226 (92+134), or 23%, which did not. slightly more than half of links with mementos, 52% (400 of 764), demonstrated some level of content drift when the a case study of electronic theses and dissertations (etds) in an academic library | massicotte and botter | https://doi.org/10.6017/ital.v36i1.9598 22 memento was compared to the current active link, while 48% (364 of 764) with mementos did not exhibit content drift. the presence of content drift by discipline, with/without mementos showing numbers of links tested, appears in table 6. discipline number of links tested content drift detected no content drift memento found memento not found total

492 364 134 498 table 6. presence of content drift by discipline, with/without mementos for links that had no memento in wayback, content drift assessment was based on the presence of an observable date in the current active link, including copyright, and/or other details which positively correlated against our extracted snippet information. for example, some links retrieved a .pdf or other static file which correlated with the snippet, there being no reason to conclude its content had undergone change since publication, despite the lack of a memento. snippets were also used in cases where a robots.txt file at the target url had prevented wayback from creating a memento. occasional examination of the dissertation text was conducted to validate information extracted in the snippet. the 23% (226) which lacked mementos remain at significant risk and will fall prey to further drift as time passes. as seen in table 7, of 492 urls manifesting content drift, 11% (54 of 492) were completely lost, linking to web domains that had been sold or were currently up for sale, and webpages replaced or removed. 9% (42 of 492) of web pages exhibited major change such that there was little correlation with snippets, or where website overhauls made assessment difficult, but not impossible. 36% (179 of 492) web links exhibited minor drift, primarily pages that differed somewhat from a memento in visual appearance, such as header and footer differences, changes in background theme or style, or changes in navigation or search functionality which did not represent a high degree of impairment. 7% (34 of 492) linked to continually updating websites, such as wikipedia and news organizations, and 7% (35 of 492) were customized 404-page-notfound, distinctive enough to warrant separate categories. a full 30% (148 of 492) exhibited a multiplicity of changes of uncertain nature which we grouped together, such as pages where graphic or audio components had been removed or could not be retrieved, broken javascript that impeded access, browser failure, mementos not accessible after repeated attempts -indicative of a range of issues affecting the quality of web archives and hence preservation.38 the types of information technology and libraries | march 2017 23 content drift encountered, broken down by broad discipline and numbers of links, and percentage, is shown in table 7. type of content drift arts business engineeri ng fine arts science total % of type lost 45 0 3 6 0 54 11% major but findable 22 0 9 9 2 42 9% minor – redesigned but recognizable 128 2 30 17 2

broad discipline though difficulties encountered during content drift assessment made further extrapolation problematic, the presence of reference rot was confirmed. our 10% stratified random sample examined 990 active links, finding that roughly half (492 of 990) manifested some degree of content drift. for 364 links, or 36% overall, a benchmark memento was found and no content drift detected. although many content drift changes can arguably be characterized as minor, it is not possible to ascertain where the content drift scale tips irremediably for any particular reader. what can be said with certainty is that 11% of active links which did not exhibit linkrot, and were quite live and accessible, fell into a small but unsettling group where the context of the cited web source is irrevocably lost. of the 498 links which did not exhibit any evidence of content drift, 134, approximately one-third, have no memento archived and continue to remain at high risk. a focused and deeper analysis of active links which might lead to a typology of content drift types would be a possible area of future study, though even the well-resourced study by jones et al. which utilized a strict "ground truth" for comparing textual mementos over time, points out that classifying links would certainly be challenging.39 a larger sample size might also allow closer analysis of disciplinary differences, which may lead to a better understanding of these types of content drift variations. conclusion reference rot in the form of linkrot and content drift were observed in etds in spectrum, our institutional repository, and this confirmation should give pause for those charged with a case study of electronic theses and dissertations (etds) in an academic library | massicotte and botter | https://doi.org/10.6017/ital.v36i1.9598 24 stewardship of etd collections. theses and dissertations have long been viewed as material which contribute overall to academic scholarly output, and carry unique status within the academy. in august 2016, opendoar registered 1600 institutional repositories with etds,40 up from 1,100 institutions as reported in 2012 by grey literature specialist schoepfel.41 academic libraries have, in large part, facilitated the transition from paper to etd with widespread adoption of institutional repository deposit programs, and along with that adoption comes a range of long-term preservation issues. yet as ohio state’s strategic digital initiatives working group pointed out, “even in digital library communities, preservation all too often stands in for or is used interchangeably with byte level backup of content.”42 for long-term access, focus can productively be shifted to offset the immediate threat of incompleteness and inadequate capture.43 not much has changed since hedstrom wrote back in 1997: “with few exceptions, digital library research has focussed on architectures and systems for information organization and retrieval, presentation and visualization, and administration of intellectual property rights … the critical role of digital libraries and archives in ensuring the future accessibility of information with enduring value has taken a back seat to enhancing access to current and actively used materials.”44 our understanding and discussion of digital preservation must be broadened, and attention turned to this key area of responsibility in the preservation life-cycle. the authors maintain that etd content and link preservation is an editorial, not individual, imperative. encouraging individual authors to perform their own archiving is doomed to fall short of even reasonable expectations. instituting measures such as perma, a distributed, redundant method of capturing and archiving web site content as part of the citation process must be pro-actively sought and built into library, and hence repository, workflows.45 browser plugins and automated solutions which use the memento protocol for capturing and archiving web site content as part of the citation process do exist,46 but naturally have to be implemented before they can take effect. either way, efforts to operationalize existing mechanisms which are designed to reduce future loss would be extremely productive. responsibility for insuring not only current, but continuing future access to etd content rests with those who maintain curatorial function of the repository. academic librarians have assumed a prominent and de facto role as curators, facilitating the role of university publication and emphasizing its break away from previous ties with commercial entities. we collectively bear greater responsibility for this body of scholarly work, and need to move forward from a position of benign neglect to one of informed curation and pro-active preservation of an important collection of scholarly output which is at risk. information technology and libraries | march 2017 25 references 1. thomas h. teper and

information over the web and in other digital environments, including digital libraries, in the form of documents such as books, articles, technical reports, etc. these documents are in a variety of formats, of which the portable document format (pdf) is most widely used because of its emphasis on preserving the layout of the original material. the retrieval of relevant material from these derivative documents is challenging for information retrieval (ir) because the rich semantic structure of these documents is lost. the retrieval of important units such as images, figures, algorithms, mathematical formulas, and tables becomes a challenge. among these elements, tables are particularly important because they can add value to the resource description, discovery, and accessibility of documents not only on the web but also in libraries if they are made retrievable and presentable to readers. sighted users comprehend tables for sensemaking using visual cues, but blind and visually impaired users must rely on assistive technologies, including textto-speech and screen readers, to comprehend tables. however, these technologies do not pay sufficient attention to tables in order to effectively present tables to visually impaired individuals. therefore, ways must be found to make tables in pdf documents not only retrievable but also comprehensible. before developing such solutions, it is necessary to review the available assistive technologies, tools, and frameworks for their capabilities, strengths, and limitations from the comprehension perspective of blind and visually impaired people, along with suitable environments like digital libraries. we found no such review article that critically and analytically presents and evaluates these technologies. to fill this gap in the literature, this review paper reports on the current state of the accessibility of pdf documents, digital libraries, assistive technologies, tools, and frameworks that make pdf tables comprehensible and accessible to blind and visually impaired people. the study findings have implications for libraries, information sciences, and information retrieval. introduction the web has a huge collection of documents, including pages, books, blogs, articles, reports, etc., available in different formats. these formats include html (hypertext markup language), epub (electronic publication), azw (amazon word), and the ubiquitous pdf (portable document format) format. pdf is layout oriented and unstructured, having elements such as text, images, tables, and metadata. all these elements carry specific information and have their relative importance. tables can be part of a structured or unstructured document. a structured table, like in html, is relatively easy to extract and interpret, as it has a starting and ending tag pair for the table itself, its headings, each row, and discrete values. however, unstructured documents, which can include books, journals, audio, video, images, and documents, do not follow a specified format or structure for the organization of information.1 a table has levels of abstraction; the higher levels mailto:nosheenfayaz@uop.edu.pk mailto:khusro@uop.edu.pk mailto:ullah@ulm.edu information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 2 of abstraction have fewer details whereas a lower level gives more information. the human has to understand and comprehend the underlying semantics of the table content for sensemaking. the content of a table has a strong bond with its context, as it has concrete information regarding the surrounding text; therefore, tables are hard to comprehend when taken out of the context. poorly conceived information is more dangerous, as it can lead to misconceptions and poor decisions. any system or component that interacts with humans must be capable of offering comprehensible explanations.2 a reader understands a table in at least three cognitive processes: comprehension, searching, and interpretation & comparison.3 in contrast, blind and visually impaired persons need assistance in comprehending the tabulated information, for example, understanding table structure and its content, searching for particular information in a table, and comparing and interpreting tabular data. therefore, they need technical solutions for reading documents.4 according to the world health organization (who), the number of blind and visually impaired people has increased significantly and has risen to 2.2 billion, so technical solutions or assistive technology are a must for their reading.5 assistive technologies are supposed to handle the three main kinds of print disabilities: vision problems, motor skill problems, and cognitive problems.6 for vision problems we have tools like text-to-speech and screen readers to help blind and visually impaired people to read text documents. however, these tools work on the upper level of abstraction and give limited information to users because they focus on text and ignore components related to presentation such as tables, graphs, images, etc. this limitation is not only found on the web but also affects other digital environments including digital libraries, where more reliable document collections are present but their retrieval and presentation to blind and visually impaired people is challenging.7 for example, a study identified the limitations of digital libraries in meeting the specific needs of blind and visually impaired people and suggested including help features for a more user-friendly experience.8 michigan state university has taken an initiative to make digital content accessible by adopting wcag 2.0 as official technical guidelines. they presented a fiveyear accessibility plan for making new, existing, and purchased content accessible along with resource allocations, training for their staff, and future requirements.9 these efforts may motivate other libraries to adopt such measures and make it a convenient place for people with disabilities. common accessibility problems include the lack of alternate descriptions, using visual cues to describe interactions in the user interface, fuzzy visuals, and audios.10 furthermore, the sightcentered nature of the digital library creates problems for blind users, such as the absence of meaningful descriptions for nontext content and instructions, along with information about the digital library’s features due to missing textual or verbal instructions.11 the traditional usage of a digital library makes a canned or routine utilization of its collections, which may be broadened by making computational ready collections.12 the accessibility of these documents will help in knowledge dissemination to blind and visually impaired people. researchers have presented frameworks and algorithms for exploring and interpreting pdf elements like images, charts, tables, and graphs. these interpretations are the basis for both humans and machines to gain meaningful insights out of tabular data. this paper highlights the significance of the rich semantics of pdf tables and the challenges in their interpretation and their presentation to blind and visually impaired people. it is proposed to present the tables’ explicit and implicit information in a progressive manner to reduce the cognitive overload on blind and visually impaired individuals. this might be achieved by providing some basic information (such as a table caption and the number of rows and columns in the table), which may be followed by information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 3 navigation and querying within the table. this stepwise approach of leveraging a table’s semantics may help in its better comprehension. table semantics will also be helpful in libraries, information science, and information retrieval, as it has the potential to improve library cataloging and classification. the next section of this paper discusses and reviews the efforts and limitations in the existing literature and presents a general model of table processing and interpretation. the prominent issues and challenges are identified regarding general table structure, format, interpretations, and evaluation; the presentation of tables to blind and visually impaired people; and specifically the accessibility issues in digital library are presented in the following section. the last section contains some future research directions that will unleash some new dynamics of this domain. the current state of table processing a table presents summarized information in a particular arrangement, where the structure of the table reveals some implicit semantics. in 1996, xinxin wang defined the logical structure and style rules of tables and presents wang’s abstract model.13 the model separated the logical structure from layout specification and is considered a generic and complete model in the literature.14 unstructured tables can be regular or irregular. a regular table has intersecting vertical and horizontal borders that develops a table of cell bounding boxes, while in an irregular table, there is no relationship between the number of rows and columns.15 tables can be n-dimensional, having spanning cells or multiline cells. tables can be long and span multiple pages and they can be floating (can be placed to the left or right of the page, with text wrapped around them). sometimes tables have no explicit boundaries and even worse, cell separators may not be visible. a table can have a variety of content that includes numerical data, text, symbols, images, and equations.16 the location of table and identification of table structure in documents is evaluated in the international conference on document analysis and recognition (icdar) table competition.17 the methods used for the identification of table structure are rule-based methods, 18 data-driven methods,19 and the graphical neural network.20 multiple frameworks and approaches are used for the extraction and processing of tables from structured documents like html,21 and unstructured documents like images and pdf documents.22 keeping in view all the conducted studies and research, we present a general model of table processing and interpretation in figure 1, showing the prominent inputs (web, pdf, and images), processes, and some notable outputs. the model has a table extraction process that is followed by processing which yields multiple outputs including organized data, analyzed structure, and analyzed content. processing can be followed by establishing relationships within the table, within table and context, or with other related tables. moreover, tables presented in open formats such as csv, xml, json, and rdf extend their potential by exploration, creating or extending ontologies and knowledge bases, and publishing tables on an lod cloud to establish links with other open data sources. below is a detailed discussion of table extraction and processing and the relationships of tables with content and context. information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 4 figure 1. a general model for table interpretation. table extraction and processing the recognition, extraction, and processing of tables, from a variety of documents, have used multiple approaches.23 the hidden table semantics will not only help in understanding tables but can also contribute to digital library cataloging. these approaches are categorized in the following sections. using heuristics different heuristic approaches are presented for extraction and processing of unstructured tables . for example, pdftrex uses spatial features and follows a bottom up approach for the recognition and extraction of tables. it represents a table as a two-dimensional grid on a cartesian plane and extracts the table as a set of cells along with their coordinates.24 in another approach, natural language processing (nlp) features are used for deeper understanding of text. these tools use parts of speech and dependency paths for the extraction of tables and for finding relations among tables by using the nlp toolkit.25 milosevic et al. presented five steps for table processing, i.e., table detection, functional analysis, structural analysis, synthetic analysis, and semantic analysis,26 while roya rastan endorses the first three steps in his phd dissertation and proposed a framework for the processing of tables. this framework consists of four layers: input management, table processing, storage, and management.27 to recognize and extract tables from documents, ad hoc heuristics are used with the existing methods and techniques, which includes three steps: (1) “preprocessing” to define and prepare text chunks from a source table by using the features of text like font, space, and bounding box; (2) “text block recovering” to identify the set of text chunks that could be treated as the content of a single cell; and (3) “cell recovering” to observe the arrangement of cells for identifying the rows and columns.28 the authors exploited appearance features of text printing instructions and position of drawing cursor for table detection and structure recognition in their web-based solution. they claimed to attain an accuracy or f-score of 83.18% for table extraction and 93.64% for structure recognition.29 furthermore, an interactive document reader was presented by the researchers of stanford university, in which structural analysis was combined with rule-based matching and natural language processing to associate a table’s values with the related text to develop sentence-table information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 5 pairs in the document. they also tried to relate tables in two data sets but unfortunately obtained 48.8 % results.30 although the results were not satisfactory, this effort opens up new endeavors for practitioners and researchers. using segmentation the segmentation approach is used for identification of tables in unstructured and untagged pdf documents, along with its columns and rows.31 visual separators and geometric content layout information is used for the extraction of tables from multiple pages of documents, and the technique is tested on e-books and scientific documents.32 ali et al. adopted a segmentation approach to deal with incomplete, impure, and complex tables by extracting table schema, data, and reading paths of data to represent in a layout independent format.33 the extraction of tables from images also used segmentation through a top-down pipeline approach. the text and tables in medical laboratory reports were identified, where the content of tables needs to be correctly captured and interpreted.34 as the medical tables include text, numbers, characters, and symbols, therefore, their correct interpretations is critical in medical reports and a minor error can lead to very dangerous outcomes. a system named texus used segmentation to prepare text chunks for finding relations among cells. the system provided end-to-end processing of tables, which claimed to detect a variety of tables in layout-independent format from a data set of complex financial tables. the system interpreted the tables and produced an xml file about the structure of the tables showing the access paths of each data cell as an attribute. 35 similarly, page segmentation is carried out by using deep learning methods to identify tables, text, and figures.36 using machine learning and deep learning approaches machine learning and deep learning techniques are also used for automatic detection and extraction of table data. random forest classifiers are used to detect a table header.37 multitask fully convolutional neural networks (fcn) are used for page segmentation to identify the tables, text block, and figure elements.38 the k-nearest neighbor method and layout heuristics are used in a system named tao for the automatic detection, extraction, and organization of data in tables in order to generate an enriched representation of data. 39 similarly, deep learning techniques like rcnn are used to capture tables from a university of las vegas data set of document images. based on the assumption that tabular data is mostly numeric, the researchers used color-coding/coloration to distinguish numeric and textual data and claim to have achieved improved performance.40 table detection and recognition in born-digital documents and images is carried out by using transfer learning for faster r-cnn in order to overcome the problem of labeled data sets and fcn semantic segmentation is used for table structure recognition. the method is evaluated using the icdar 2013 data set.41 another approach, named decnt, worked on images (in any format) for the extraction of tables by using a combination of deformable cnn with faster r-cnn/fpn. the method is evaluated using the icdar 2013 data set and the icdar 2017 pod data set, unlv, mormont.42 in other research, the authors pointed out the weakness in the existing methods and techniques for understanding tables and presented a “graph neural network” approach to analyze the structure of pdf tables and handle the spanning cells.43 along with that, multiple deep learning techniques are used for integrating and querying tables using word embedding, rnn, knn, and lstm for the classification of financial tables. 44 in the case of web tables, annotation of table columns is performed by using convolutional neural network (cnn) along with transfer learning information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 6 in order to overcome the problem of a shortage of target data sets. the column semantics are embedded into vector space and are used for predicting the type of columns without using the metadata. the method is tested on two web table data sets, t2dv2 and limaye.45 using ontologies ontologies have also played a vital role in the detection, recognition, and annotation of tables from the web, images, and pdf documents. ontologies consider the content and structure of a table for their conceptual representation. a system named tableminer was used to interpret the tables semantically by identifying the semantic concepts for the columns and disambiguating the cell content by using rdfa and microdata for improved annotations of the table. 46 tableminer considered relational tables and mapped the headers of table with the properties of ontology for linking the cell values with entities.47 the relationships between a table and its context are also extracted and annotated, and to remove disambiguation, the provenance of relationships is preserved.48 a framework named tabel, developed by varish mulwad, has a module for converting a table to a graphical model to infer the semantics of table header, cells, and their relation to each other. these semantics are used to convert the graphical representation to rdf triples by using knowledge bases along with the author’s own defined ontology or any other ontology.49 the ontology is also used for finding the relevant tables in a domain of technical documents only.50 for easy interpretation by ontologies and more usability of the government data, the unstructured tabular data is suggested to be published in open format like csv (comma separated value).51 the studies mentioned above have mostly used relational tables, technical document tables, government data, and medical data with a main objective of making tables open and interrelated. along with that, another study argued that besides the metadata of a resource, user-generated content may also be considered and published as linked open data for improved consumption and would also contribute to better cataloging of digital libraries.52 unfortunately, it still has problems like disambiguation and correlation of complex tables, besides other issues involved in publishing and consuming data as open and linked data.53 relationship of tables with content and context the content of a table is present in a particular arrangement in order to give some specific information. therefore, the table content should be interpreted for the hidden semantics among the cell content, context, and with other related tables in a particular domain. in this reg ard, natural language techniques are used for the identification of relationships in the table and the related text using the nlp toolkit. the researchers claimed improvement in table schema identification and quality of relation.54 similarly, ontologies are used to identify the semantic relations among the text, table contents, and table structure.55 another research project used rulebased matching and structural analysis for finding the relationship in table cell and sentence text, by developing sentence-table pair in the document. this project tried to develop a relationship between tables of two data sets but achieved only 48.8% success rate.56 a system named texus tried to find out the relations among the values of cells using cell entries, categories, and access paths. they used segmentation techniques for preparation of text chunks and produced an xml file about the structure of the table showing the access paths of each data cell as an attribute.57 narrowing the table-understanding domain to clinical literature, with a focus on just the numerical and textual data of tables from xml documents, milosevic et al. extended their previous work and tried to identify the relationship between the table and the surrounding text. they added pragmatic analysis, cell selection, and syntactic analysis, defined five categories of cells, depending upon the data in the cells, and identified seven semantic categories for the information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 7 specification of table extraction process. the pubmedcentral data set is used to test the developed system with regard to task, variables and complexity. the authors claimed to achieve an accuracy measure f-score between 82% and 92%.58 a “graph neural network” model was developed to build an undirected graph for the prediction of relations among adjacent cells. the model was tested on benchmark data sets, i.e., icdar 2013 and tablebank-2019, and claimed to outperform.59 another system, named tablepedia, unified the tables of experimental results with regard to method, data set, metric, score, and source into tuples. the system extracted the related tables and identified the conflicted results by using the rule-based and learning-based methods with the help of sql operations.60 an sql-like query was proposed for the financial tables in pdf formats by using deep learning approaches.61 all the mentioned techniques for establishing relationships follow the rule-based, learning-based, segmentation, neural network, heuristics, and ontologies. among these, the ontologies can establish inter domain relationships and explorations. however, it still has issues that will be discussed in the conclusion section. existing accessibility-driven solutions for pdf documents apart from the systems and frameworks for table understanding and processing, a mech anism or a solution is needed to present tables in a meaningful way to blind and visually impaired people. the accessibility of digital documents is based on the captured structural information and its availability for processing by other software and applications, such as tagged pdf, can help in summarizing, navigating, and providing structural information of the content.62 nazimi made an effort to present a framework for understanding the complex documents and its components, including images, charts, and tables, in a nonvisual representation to blind and visually impaired people.63 the existing available solutions for reading pdf documents to blind and visually impaired people focus on text and give little attention to its elements such as tables, images, graphs, and charts. particularly speaking for tables, these solutions either read the table caption and ignore the content, or read the table as if it were text, which renders it meaningless. these assistive technologies are divided into four main categories. 1. text-to-speech tools 2. screen readers 3. voice assistant 4. natural language generator (nlg) text to speech tools include products like wordtalk, virtual speaker, audiobook reader voice, voicepaper, dream reader, etc. these tools can read text from txt, pdf, or doc files aloud and have an interface for user interaction, where the user can copy-paste the text or mention the path of the file to read. some of the tools are free with limited features while others are proprietary. they need human interaction, which might be difficult to use for a visually impaired or blind person. screen readers include jaws, nvda, cobra, voiceover, and talkback. they speak out every user activity that is taking place, like opening or closing a window, clicking on a button, reading text from a txt or pdf file. these tools are helpful for visually impaired people, as they do not need the user to open a specific software and then specify the path of files to read. the most popular tool , jaws, is proprietary and used for windows. nvda is free software for windows, while voiceover is a free tool provided with apple’s operating systems (including macos and ios). nvda reads the text, taking note of punctuation; it reads the table row by row like text and then reads the caption of the table at the end. it can also read the alternate text of the table if it is included in acrobat pro. these tools need the user to be aware of what he or she is doing. information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 8 similarly, there are voice assistants like apple siri, microsoft cortana, google assistant, and amazon alexa. all these tools take instructions from the user and then try to provide solutions. these tools may ask users several queries to clarify what they want and provide limited functionalities such as reading out gps coordinates, playing music, etc. the natural language generator (nlg) is used to convert raw text or data into narrations. existing popular systems or tools include arria nlg, quill, ibm watson, ax nlg cloud, amazon polly, and wordsmith. these systems are used to perform data analysis and convert the extracted analytics to narrations, which could be easily understand by the user. these tools are not for narrating tables from unstructured documents. however, a framework has been developed using a neural encoder-decoder to generate text from tables. it is claimed that the solution outperformed the existing solutions and achieved higher bleu score and f-score using data sets weathergov, wikibio, wikitable, and a chinese data set wikibiocn.64 this technique focuses on formal tables and ignores complex tables as well as unstructured pdf. a new emerging category in this paradigm is the document-centered assistant, which tries to help users review documents by asking questions. the field is currently studied for the type of questions that a user may ask and the candidate machine learning models that can be used for answering them. the questions would be different from factoid questions and chitchat, because here the focus would be on relevant information from that specific document.65 this category seems to have a big scope for understanding, reviewing, and inferring knowledge from documents. apart from the solutions mentioned above, there are some java and python tools and libraries that are used for table extraction from pdf documents and are shown in table 1. some of the tools are commercial and claim to extract tables, table rows, and even table cells from documents and images, like pdftables, docparser, and pdftron. similarly, there are also open-source java and python libraries for table and metadata extraction from images and documents. the libraries that extract tables from images are camelot, excalibur, and pdfplumber, whereas the libraries that extract tables from non-image-based documents are tabula, pypdf2, pdf table extractor, pdfplumber, and pdfminer. among these five, pdf table extractor is browser-based and pdfminer works with structured tables and digs out the semantic relations. for working with unstructured tables in pdf documents and developing a table extractor component for an integrated environment, tabula, pdfplumber, and pypdf2 might be better choices. the research and solutions mentioned above regarding table detection and understanding are carried out to make them meaningful to machines and humans who have no visual impairment or dyslexia. therefore, the future documentation may consider the inclusion of translations and lay summaries (concise descriptions in simple words) of objects or elements within the document, as essential components, to make them accessible to blind and visually impaired individuals as well.66 in this regard, the world wide web consortium (w3c) developed the web accessibility guidelines for developing web documents to make the nontext elements accessible. these guidelines include elements such as captions for tables and figures, description of figures, and summaries of the tables.67 similarly, html has tags to include summaries of a table, including <summary>, <span>, <p id= “tbldesc”>. microsoft word has an option “text alternative” to add a description of a table or figure for visually impaired people, who will use screen readers for reading the document. adobe acrobat reader also has an accessibility pane to tag tables and add alternative text and descriptions of tables, which is used by the nvda screen reader to read aloud. moreover, commonlook office, whose motto is “build accessibility into documents early,” has add-ins for microsoft word or powerpoint to add enough accessibility content to the documents to information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 9 table 1. solutions and libraries for table extraction and processing. s no. tools open source image based comments 1 tabula y n

accessible. however, already-developed unstructured documents, without any accessibility features, still need some measures to make the documents understandable to visually impaired or blind users. keeping in mind the statistics of visually impaired people and the unstructured data of the future—the global data sphere will grow from 33zb to 175zb and 80% of this worldwide data will be unstructured—visually impaired individuals cannot be ignored for their access to knowledge.68 therefore, we would need mechanisms for making these unstructured documents understandable to as many people as possible by incorporating accessibility measures in the document readers. the following section highlights some of the key issues in this domain. issues and challenges in the existing systems tables can be utilized in multiple scenarios including information extraction, table search, ontology engineering, conversion to dbms, and document engineering. 69 the situation becomes difficult when a blind or visually impaired person needs to understand the tables. the issues and challenges in dealing with pdf tables are categorized in the following sections.

https://resourcegovernance.org/analysis-tools/tools/pdf-table-extractor information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 10 table structure tables in pdf documents need more focus on table structure detection because they do not follow a defined formal structure.70 several knowledge gaps are identified in literature regarding table structure, such as the identification of functional areas of tables, for which silva argued the use of multiple heuristics and machine learning algorithms in parallel or in sequence.71 the variety of structural layouts creates problems in their identification, which can be handled by defining more rules at the lexical and syntactic layer of table processing. this could also be fruitful for better semantic annotations.72 in addition, the variety of cell content or inconsistent cell content, along with implicit header cells, creates problems in understanding the tables, especially by machines.73 the vector representation of web tables may be applied to pdf tables for semantic annotations and identification of column types.74 along with that approach, graphical representation and a graphical neural network (gnn) can also be used for better structure identification in multiple domains.75 new data sets need to be introduced for structure recognition in various domains, including business and finance, as they use a huge amount of tables in their documents.76 from the discussion above, the table structure inconsistencies, cell content inconsistencies, functional and logical processing of tables needs more research effort to eliminate the stated problems. along with that, the inclusion of more data sets will also help in handling the diversity in the field. table formats the existing format of tables in pdf lacks the metadata needed for further processing; therefore, the conversion of pdf tables to other formats, especially open formats, will open new endeavors. some researchers have worked on converting tables to csv format, which retains the basic structure but lacks some cell formatting. researchers worked on the transformation of web tables to relational tables for easy manipulation.77 in contrast, xml can handle complex data and is more easily read by humans. therefore, a methodology is presented to work on tables in xml format, but it considers tables having text and numerical data only.78 json, another format, can also be used as an alternative to xml; it is smaller in size than the xml and can handle complex and hierarchical data. the json format has less support than xml but is preferred for web application due to its interoperability and lightweight features. table interpretation the variable representation patterns of table values, dense content and natural languag e processing create problems in the correct interpretation of tables.79 anaphoric resolution techniques and documenting level discourse parsers are suggested to handle complex references among multiple domains.80 moreover, handling the locality features of a table and the annotation of its property feature can lead to better interpretation of tables.81 the use of a knowledge base is suggested for understanding and annotating the relationships among tables and text to get more information about the extracted entities from tables and text.82 similarly, the extraction of data and its precision in medical and financial tables is an issue that needs the attention of researchers, as both fields have crucial and important data in its tables. 83 for easy interpretation of tables, machine learning classifiers, based on table headings and captions, can be used to classify them into their respective domain.84 the relationship of tables in a specific domain and or among multiple domains can be achieved by developing ontologies.85 this will enable the tables to be published on an lod cloud that will establish more relationships and infer insights from multiple domains. information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 11 table evaluation most of the researchers working on pdf tables have tried to evaluate their work with popular data sets such as icdar 2013, icdar 2015, icdar 2017 pod, pubmed, unlv, and mormont. as we have pdf documents in multiple domains, therefore, new data sets should be introduced for structure recognition, especially in business and finance, as these domains use a large number of tables in their documents.86 an evaluation methodology was proposed for table detection, structure recognition, and its functional and semantic analysis.87 unfortunately, there are no standard metrics, parameters, and formal methodology for table processing evaluation.88 therefore, standard evaluation metrics should be defined for pdf tables, in order to standardize the evaluation of algorithms and frameworks. table presentation to blind and visually impaired users the available tools and techniques for reading aloud documents to blind and visually impaired people either read the table caption only and ignore the content or treat the tables as text and read the rows line by line. this does not help these users to understand the semantics of the table and its content. besides the content of the table, its layout shows grouping and connections among the content which is not presented to blind and visually impaired people by current solutions.89 therefore, tools and screen readers need to present tables in nonvisual format or give a summarized view of tables by following the guidelines of w3c, instead of reading the table like text.90 the summarized view of tables can become part of bibliographic metadata and can contribute in cataloging in the perspective of linked and open data. 91 a study highlighted the accessibility of published pdf articles by four journal publishers and presented the findings in graphs to show the trend from 2009 to 2013, by taking parameters including meaningful title, alternate text for images, and logical reading order.92 the author further applied the same methodology to analyze the articles published in next four years (2014 to 2018) and came to the conclusion that accessibility of pdf documents had improved. however, the journal publishers , who should be more aware of disability and accessibility, did not consistently follow the pdf/ua accessibility requirements and wcag 2.0 when producing pdf versions of their articles.93 therefore, visually impaired individuals should be provided with a mechanism for understanding the digital content and underlying semantics at multiple levels of abstractions, like the general information about the document and its elements—including tables—its structure and content, navigation in the table, and querying the table to get more details and lessen cognitive overload. accessibility of digital library collection the accessibility of large-scale digital library collections can enhance content for sighted as well as visually impaired users. the traditional utilization of digital library collections needs to be broadened by making computation-ready collections meant to be used and consumed in multiple domains.94 an effort was made by researchers to digitize and archive a digital repository of images and convert them to pdf/a documents but, unfortunately, the researchers came up with limited semantics as they did not consider the elements within the documents themselves.95 the accessibility of these converted documents may be compromised with these limited semantics. the rich semantics of tables can be used in the bibliographic classification of a digital library’s collection to increase the search width of the digital library.96 blind and visually impaired users can be assisted in using digital libraries, as they may need help at physical and cognitive levels. at the physical level, the blind may face difficulty in accessing information, identifying path and status, and efficiently evaluating information. at the cognitive level, they may face problems in understanding multiple structures, programs, information, features of the digital library, and the need to stick to some specific formats. therefore, the inclusion of help features will make the information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 12 digital library friendly to blind and visually impaired people by incorporating meaningful descriptions for nontextual elements.97 the sight-centered nature of the digital library creates problems for blind and visually impaired users due to missing textual or verbal instructions. some researchers identified the inclusion of labels and meaningful descriptions for hyperlinks, instructions, structure, multimedia content and nontext content to make digital libraries friendly to blind and visually impaired people.98 at the same time, others argue for improvement in usability by introducing help features in terms of usefulness, ease of use, and user satisfaction.99 the accessibility of digital libraries in general and its content in specific may be improved by accommodating help features in the interface and meaningful descriptions for the contents’ nontext elements including tables. conclusions and future research directions this study discusses the accessibility of tables included in pdf documents in general as well as in the specific environment of digital libraries. existing frameworks, algorithms, and solutions for the processing and interpretation of pdf tables, specifically their presentation to blind and visually impaired people, are thoroughly discussed. a general workflow of table processing is also presented in figure 1. the available solutions for reading out pdf documents to blind and visually impaired people are analyzed for their output, specifically for their attitude towards handling tables. furthermore, a list of resources for table interpretation and presentation are discussed along with their different features. the issues and challenges in table structure, format, interpretation, evaluation, its presentation to blind, and accessibility of digital library collection are discussed. the researchers working in the domain of accessibility, digital library, and pdf tables can extend and modify the current solutions and algorithms by following the future research directions given below. • the structure of a table has implicit semantic information which a sighted reader can infer but a blind reader needs assistance to understand. the structure of a pdf table is extracted using multiple approaches like heuristics, ontologies, machine learning and segmentation, whereas vectors are used for a web table.100 therefore, the combinations of multiple approaches and use of vectors for pdf tables may produce better results. • the content of a table is usually numeric or very short text and needs proper interpretation. therefore, a knowledge base can be used to get more information about the extracted entities from tables and text in order to understand and annotate the relationships among tables and text.101 these knowledge bases can be predetermined or may be selected automatically according to the table content or domain. • table interpretation can become easy if tables are classified according to their domains by using machine learning classifiers. the classification can be based on table headings and captions, as well as the title and author of the document.102 • ontologies are used to relate the tables in a specific domain and or among multiple domains, and publishing them on an lod cloud will establish new relationships.103 this will help in inferring new insights from complex, long, and numerical tables. • unstructured data and content can be made available for multiple usage and interpretations if it is converted to open formats like csv, json and xml.104 among these, csv comes with repeated content, xml needs special parsers, whereas json is lightweigh t and easy to write and read.105 it has support from nosql databases like mongodb and apache couchdb, and web application apis like twitter, you tube, and facebook. information technology and libraries september 2021 accessibility of tables in pdf documents | fayyaz, khusro, and ullah 13 therefore, json might be a better option for the conversion of pdf tables for its multiple interpretation and navigation within tables. • the processes used for evaluation of tables have no defined matrices.106 therefore, the table evaluation processes should be defined with their respective matrices in order to standardize the research in this domain. • the precision of extracted content of table is very crucial especially in medical, financial, and experimental tables that have numeric data. therefore, the preprocessing of tables or conversion to other formats would need more attention to avoid any truncation or round off of the data. • the presentation of tables to blind or visually impaired people can be in nonvisual or summarized form.107 the summaries may be presented nonvisually, including the structural layout as well as a brief introduction of the table, to minimize the cognitive overload on these individuals. • to evaluate the accessibility of digital library interfaces, 16 heuristics were proposed to make the digital libraries in reach of users, however, more heuristics are needed to make generalized interfaces for all individuals.108 • the nontext elements of digital library collections should have meaningful descriptions for better understandability of blind and visually impaired individuals. the user-generated content about these nontext elements could be used for cataloging.109 • the rich semantics of tables can be exploited for cataloging and classification that will be helpful in exploratory searching. • as the michigan state university libraries has taken the initiative of assessing and improving the accessibility of digital library content by adopting the wcag guidelines, other libraries can also adopt the model for providing accessible content to their users including blind and visually impaired individuals. • the development of new data sets for tables in multiple domains can facilitate the researchers in interpreting tables and establishing relationships in cross-domains. this review paper is an attempt to highlight the knowledge gap in processing the pdf tables and its accessibility for blind and visually impaired individuals. an efficient and open-source solution for making pdf documents accessible to blind and visually impaired people needs to exploit the heuristics, ontologies, machine learning, and deep learning by using open-source libraries and tools for understanding and interpreting the tabular content in order to reduce information overload. endnotes 1 roya rastan, “automatic tabular data ex wcag traction and understanding” (phd diss., university of new south wales, 2017). 2 mark t. maybury, “communicative

libraries; dec 2004; 23, 4; proquest pg. 198 book review free culture how big media uses technology and the law to lock down culture and control creativity by lawrence lessig . new york: penguin, 2004. 240p. $24.95 (isbn 1594-20006-8). this is the third book by stanford law professor larry lessig, and the third in which he furthers his basic theme : that the ancient regime of intellectual property owners is locked in a battle with the capabilities of new technology. lessig u sed his first book, code and other laws of cyberspace (basic books, 1999), to explain that the notion of cyberspace as free, open, and anarchic is simply a myth, and a dangerous one at that: the very architecture of our computers and how they communicate determine what one can and cam10t do within that environment. if you can get control of that architecture, say by mand ating filters on cont ent, yo u can get subs tantial control over the culture of that communication space. in his sec ond book, the future of ideas: the fate of the commons in a connected world (random, 2001), lessig describes how the chang e from real prop erty to virtual propert y actually means more opportunity for control , not less. the theme that he takes up in free culture is his conc ern that certain powerful inter ests in our society (read: hollywood) are using copyright law to lock down the very stuff of creativity: mainly , pa st creativity. lessig himself admits in his preface that his is not a new or unique argument. he cites richard stallman's writings in the mid-1980s that became the basis for the free software movement as containing many of the same concepts that lessig argues in his book. in this case, it serves as a kind of proof of concept (that new ideas build on past ideas) rather than a criticism of lack of originality. stallman's work is not, however, a substitute for lessig's; not only does lessig address popular culture where stallman addresses only computer code, but lessig has one key thing in his favor: h e is a mast er story-tell er and a darned good writer, not something one usually expec ts in an academic and an expert in constitutional law. his book opens with the first flight osf the wright brothers and the death of a farmer's chick ens, followed by buster keaton's film steamboat bill and disney's famous mouse . th e next chapter traces the history of photography and how the law once considered that snapping a picture could require prior permission from the owners of any property caught in th e viewfinder. later he tells how an improvement to a sea rch engin e led one college student to owe the recording industry association of america $15 million. throughout the book lessig illustrates copyright through the lives of real people and uses histor y, science, and the arts to mak e this law come to life for the reader . lessig explains that intellectual property differ s from real property in the eye of the law. unlike real property, where th e property owner has near total control over its uses, the only control offered to authors originally was the control over who could make copies of the work and distribut e them. in addition, that right-the "copy right" -lasted only a short time. the original length of copyright in the united states was fourteen years, with the right to renew for another fourteen years. so a total of twenty-eight years stood betwe en an author's rights and the public domain, and those rights were limited to publishing copies. others could quote from a work, even derive other works from it (such as turning a no ve l into a play) , all within a law that was designed to promote science and the arts. fast forward to the present day and we have a very different situation. not only has there been a change in th e length of time that copyright applies to a work; a major change in 198 information technology and libraries i december 2004 tom zillner, editor copyright law in 1976 extended copyright to works that had not previously b een covered. in the earli es t u.s. copyright regimes of the late 18th century, only works that were registered with the copyright office were afforded the prot ection of copyright law, and only about five perc en t of works produc ed were so registered. th e rest were in the public domain. later, actual registration with the copyright office was unnecessary but the author was required to place a copyright notice on a work (e.g ., "© 2004, karen coyle") in order to claim copyright in it. copyright holder s had to renew works in order make use of the full term of protection, and renewal rates were actually quite low. in 1976, all such requirements were removed, and the law was amended to state that any work in a fixed m edium automatically receives copyright protection, and for the full term. that is true even if the author do es not want that protection . so although many saw the great exchange of ideas an d information on the internet as being a huge commons of knowledge, to be shared and sha red alike, a ll of it has, in fact, alwa ys been covered by copyright law-every word out there belongs to someone. that chang e, combined with a much earlier change that gave a copyright holder control over derivative works, puts creators into a deadlock. th ey cannot safely build on the work of others without permission (thus less ig's argument that we are becomin g a "permission culture ") . yet, we have no m echanism (such as registration of works that would result in a databas e of creators) that would facilitate getting th at permission . if you find a work on the internet and it has no named author or no contact information for the author, the law forbids you to reuse the work without permission, but there is nothing that would make getting that permission a manageable task. of course, even if you do know who th e rights hold er is , permission is not a given. for examreproduced with permission of the copyright owner. further reproduction prohibited without permission. ple, you hear a great song on the radio and want to use parts of that tune in your next rap performance. you would need to approach the major record label that holds the rights and ask permission, which might not be granted. you could go ah ead and use the sample and, if challenged, claim "fair use." but being challenged means going to court in a world where a court case could cost you in the six digits, an amount of money that most creators do not have. lessig, of course, spends quite a bit of time in his book on the length of copyright, now life of the author plus seventy years. it was exactly this issue that he and eric eldred took to the supreme court in 2003. lessig argued before the court that if congress can seemingly arbitrarily increase the length of copyright, as it has eleven times since 1962, then there is effectively no limit to the copyright term. yet "for a limited time" was clearly mandated in the u.s. constitution. lessig lost his case. you might expect him to spend his efforts explaining how the supreme court was wrong and he was right, but that is not what he does . right or wrong, they are the supreme court, and his job was to convince them to decide in favor of his client. instead, lessig revises his estimation of what can be accomplished with constitutional arguments and spends a chapter outlining compromises that mightjust might-be possible in the future. to the extent that eldred v. ashcroft had an effect on lessig's thinking , and there is evidence that the effect was profound, it will have an effect on all of us because lessig is one of the key actors in this arena. throughout the book, lessig points out the difference between copyright law and the actual market for works. there is a great irony in the fact that copyright law now protects works for a century or more while most books are in print for one year or less. it is this vast storehouse of out-ofprint and unexploited works that makes a strong argument for some modification of our copyright law. he also recognizes that there are different creative cultures in our society, with different views of the purpose of creation. here he cites academic movements like the public library of science as solutions for the sector of society that has a low or nonexistent commercial interest but a need to get its works as widely distributed as possible. for these creators, and for "sharers" everywhere, lessig promotes the creativecommons solution (at www. creativecommons.org), a simple licensing scheme that allows creators to attach a license to their work that lets others know how they can make use of it. in a sense, creativecommons is a way to opt out of the default copyright that is applied to all works. when i first received my copy of free culture, i did two things: i looked up libraries in the index, and i looked up the book online to see what other reviewers had said. online, i found a web site for the book (http:/ /free-culture.org) that pointed to two very interesting sites: one that lists free, downloadable fulltext copies of the book in over a dozen different formats; and one that allows you to listen to the chapters being read aloud by volunteers and admirers. (i did listen to a few chapters and generally they are as listenable as most nonfiction audio books. in the end, though, i read the hard copy of the book.) lessig is making a point by offering his work outside the usual confines of copyright law, but in fact the meaning of his gesture is more economic than legal. although he, and cory doctorow before him (down and out in the magic kingdom, tor books, 2003), brokered agreements with their publishers to publish simultaneously in print with free digital copies, few authors and publishers today will choose that option for fear of loss of revenue, not because of their belief in the sanctity of intellectual property. if there were sufficient proof that free online copies of works increased sales of hard copies, this would quickly become the norm, regardless of the state of copyright law. as for libraries-unfortunately, they do not fare well. he dedicates a short chapter to brewster kahle and his way-back machine as his example of the need to archive our culture for future access. i admit that i winced when lessig stated: but kahle is not the only librarian. the internet archive is not the only archive. but kahle and the internet archive suggest what the future of librarie s or archives could be. (114) lessig also mentions libraries in his arguments about out-of-print and inaccessible works, but in this case he actually gets it wrong: after it [a book] is out of print , it can be sold in used book store s without the copyright owner getting anything and stored in libraries, where many get to read the book, also for free. (113) since we know that lessig is very aware that books are sold and lent even while they are still in print, we have to assume that the elegance of the argum ent was preferred over precision . but he makes this error mor e than once in the book, leaving librarie s to appear to be a home for leftov ers and remaindered works. that is too bad. we know that lessig is aware of libraries; anyone active in the legal profession depends on them. he has spoken at library-related conferences and events. yet he does not see libraries as key players in the battle against overly powerful copyright interests . more to the point, libraries have not captured his imagination, or given him a good story to tell. so here is a challenge for myself and my fellow librarians: whether it means chatting up lessig after one of his many public performances, becoming active in creativecommons, or stopping by palo alto to take a busy law professor to lunch , we need to make sure that we get on , and stay on, lessig's radar . we need him ; h e needs us.-karen coyle, digital libraries consultant, http:// kcoyle.net book review 199 58 information technology and libraries | june 2010 know its power, and facets can showcase metadata in new interfaces. according to mcguinness, facets perform several functions in an interface: ■■ vocabulary control ■■ site navigation and support ■■ overview provision and expectation setting ■■ browsing support ■■ searching support ■■ disambiguation support5 these functions offer several potential advantages to the user: the functions use category systems that are coherent and complete, they are predictable, they show previews of where to go next, they show how to return to previous states, they suggest logical alternatives, and they help the user avoid empty result sets as searches are narrowed.6 disadvantages include the fact that categories of interest must be known in advance, important trends may not be shown, category structures may need to be built by hand, and automated assignment is only partly successful.7 library catalog records, of course, already supply “categories of interest” and a category structure. information science research has shown benefits to users from faceted search interfaces. but do these benefits hold true for systems as complex as library catalogs? this paper presents an extensive review of both information science and library literature related to faceted browsing. ■■ method to find articles in the library and information science literature related to faceted browsing, the author searched the association for computing machinery (acm) digital library, scopus, and library and information science and technology abstracts (lista) databases. in scopus and the acm digital library, the most successful searches included the following: ■■ (facet* or cluster*) and (usability or user stud*) ■■ facet* and usability in lista, the most successful searches included combining product names such as “aquabrowser” with “usability.” the search “catalog and usability” was also used. the author also searched google and the next generation catalogs for libraries (ngc4lib) electronic discussion list in an attempt to find unpublished studies. search terms initially included the concept of “clustering”; however, this was quickly shown to be a clearly defined, separate topic. according to hearst, “clustering refers to the grouping of items according to some measure faceted browsing is a common feature of new library catalog interfaces. but to what extent does it improve user performance in searching within today’s library catalog systems? this article reviews the literature for user studies involving faceted browsing and user studies of “next-generation” library catalogs that incorporate faceted browsing. both the results and the methods of these studies are analyzed by asking, what do we currently know about faceted browsing? how can we design better studies of faceted browsing in library catalogs? the article proposes methodological considerations for practicing librarians and provides examples of goals, tasks, and measurements for user studies of faceted browsing in library catalogs. m any libraries are now investigating possible new interfaces to their library catalogs. sometimes called “next-generation library catalogs” or “discovery tools,” these new interfaces are often separate from existing integrated library systems. they seek to provide an improved experience for library patrons by offering a more modern look and feel, new features, and the potential to retrieve results from other major library systems such as article databases. one interesting feature these interfaces offer is called “faceted browsing.” hearst defines facets as a “a set of meaningful labels organized in such a way as to reflect the concepts relevant to a domain.”1 labarre defines facets as representing “the categories, properties, attributes, characteristics, relations, functions or concepts that are central to the set of documents or entities being organized and which are of particular interest to the user group.”2 faceted browsing offers the user relevant subcategories by which they can see an overview of results, then narrow their list. in library catalog interfaces, facets usually include authors, subjects, and formats, but may include any field that can be logically created from the marc record (see figure 1 for an example). using facets to structure information is not new to librarians and information scientists. as early as 1955, the classification research group stated a desire to see faceted classification as the basis for all information retrieval.3 in 1960, ranganathan introduced facet analysis to our profession.4 librarians like metadata because they jody condit fagan (faganjc@jmu.edu) is content interfaces coordinator, james madison university library, harrisonburg, virginia. jody condit fagan usability studies of faceted browsing: a literature review usability studies of faceted browsing: a literature review | fagan 59 doing so and performed a user study to inform their decision. results: empirical studies of faceted browsing the following summaries present selected empirical research studies that had significant findings related to faceted browsing or interesting methods for such studies. it is not an exhaustive list. pratt, hearst, and fagan questioned whether faceted results were better than clustering or relevancy-ranked results.11 they studied fifteen breast-cancer patients and families. every subject used three tools: a faceted interface, a tool that clustered the search results, and a tool that ranked the search results according to relevance criteria. the subjects were given three simple queries related to breast cancer (e.g., “what are the ways to prevent breast cancer?”), asked to list answers to these before beginning, and to answer the same queries after using all the tools. in this study, subjects completed two timed tasks. first, subjects found as many answers as possible to the question in four minutes. second, the researchers measured the time subjects took to find answers to two specific questions (e.g., “can diet be used in the prevention of breast cancer?”) that related to the original, general query. for the first task, when the subjects used the faceted interface, they found more answers than they did with the other two tools. the mean number of answers found using the faceted interface was 7.80, for the cluster tool it was 4.53, and for the ranking tool it was 5.60. this difference was significant (p<0.05).12 for the second task, the researchers found no significant difference between the tools when comparing time on task. the researchers gave the subjects a user-satisfaction questionnaire at the end of the study. on thirteen of the fourteen quantitative questions, satisfaction scores for the faceted interface were much higher than they were for either the ranking tool or the cluster tool. this difference was statistically significant (p < 0.05). all fifteen users also affirmed that the faceted interface made sense, was helpful, was useful, and had clear labels, and said they would use the faceted interface again for another search. yee et al. studied the use of faceted metadata for image searching, and browsing using an interface they developed called flamenco.13 they collected data from thirty-two participants who were regular users of the internet, searching for information either every day or a few times a week. their subjects performed four tasks (two structured and two unstructured) on each of two interfaces. an example of an unstructured task from their study was “search for images of interest.” an example of a structured task was to gather materials for an art history of similarity . . . typically computed using associations and commonalities among features where features are typically words and phrases.”8 using library catalog keywords to generate word clouds would be an example of clustering, as opposed to using subject headings to group items. clustering has some advantages according to hearst. it is fully automated, it is easily applied to any text collection, it can reveal unexpected or new trends, and it can clarify or sharpen vague queries. disadvantages to clustering include possible imperfections in the clustering algorithm, similar items not always being grouped into one cluster, a lack of predictability, conflating many dimensions, difficulty labeling groups, and counterintuitive subhierarchies.9 in user studies comparing clustering with facets, pratt, hearst, and fagan showed that users find clustering difficult to interpret and prefer a predictable organization of category hierarchies.10 ■■ results the author grouped the literature into two categories: user studies of faceted browsing and user studies of library catalog interfaces that include faceted browsing as a feature. generally speaking, the information science literature consisted of empirical studies of interfaces created by the researchers. in some cases, the researchers’ intent was to create and refine an interface intended for actual use; in others, the researchers created the interface only for the purposes of studying a specific aspect of user behavior. in the library literature, the studies found were generally qualitative usability studies of specific library catalog interface products. libraries had either implemented a new product, or they were thinking about figure 1. faceted results from jmu’s vufind implementation 60 information technology and libraries | june 2010 uddin and janacek asked nineteen users (staff and students at the asian institute of technology) to use a website search engine with both a traditional results list and a faceted results list.22 tasks were as follows: (1) look for scholarship information for a masters program, (2) look for staff recruitment information, and (3) look for research and associated faculty member information within your interested area.23 they found that users were faster when using the faceted system, significantly so for two of the three tasks. success in finding relevant results was higher with the faceted system. in the post–study questionnaire, participants rated the faceted system more highly, including significantly higher ratings for flexibility, interest, understanding of information content, and more search results relevancy. participants rated the most useful features to be the capability to switch from one facet to another, preview the result set, combine facets, and navigate via breadcrumbs. capra et al. compared three interfaces in use by the bureau of labor statistics website, using a between-subjects study with twenty-eight people and a within-subjects study with twelve people.24 each set of participants performed three kinds of searches: simple lookup, complex lookup, and exploratory. the researchers used an interesting strategy to help control the variables in their study: because the bls website is a highly specialized corpus devoted to economic data in the united states organized across very specific time periods (e.g., monthly releases of price or employment data), we decided to include the us as a geographic facet and a month or year as a temporal facet to provide context for all search tasks in our study. thus, the simple lookup tasks were constructed around a single economic facet but also included the spatial and temporal facets to provide context for the searchers. the complex lookup tasks involve additional facets including genre (e.g. press release) and/or region.25 capra et al. found that users preferred the familiarity afforded by the traditional website interface (hyperlinks + keyword search) but listed the facets on the two experimental interfaces as their best features. the researchers concluded, “if there is a predominant model of the information space, a well designed hierarchical organization might be preferred.”26 zhang and marchionini analyzed results from fifteen undergraduate and graduate students in a usability study of an interface that used facets to categorize results (relation browser ++).27 there were three types of tasks: ■■ type 1: simple look-up task (three tasks such as “check if the movie titled the matrix is in the library movie collection”). ■■ type 2: data exploration and analysis tasks (six tasks essay on a topic given by the researchers and to complete four related subtasks. the researchers designed the structured task so they knew exactly how many relevant results were in the system. they also gave a satisfaction survey. more participants were able to retrieve all relevant results with the faceted interface than with the baseline interface. during the structured tasks, participants received empty results with the baseline interface more than three times as often as with the faceted interface.14 the researchers found that participants constructed queries from multiple facets in the unstructured tasks 19 percent of the time and in the structured tasks 45 percent of the time.15 when given a post–test survey, participants identified the faceted interface as easier to use, more flexible, interesting, enjoyable, simple, and easy to browse. they also rated it as slightly more “overwhelming.” when asked to choose between the two, twenty-nine participants chose the faceted interface, compared with two who chose the baseline (n = 31). thirty-one of the thirty-two participants said the faceted interface helped them learn more, and twentyeight of them said it would be more useful for their usual tasks.16 the researchers concluded that even though their faceted interface was much slower than the other, it was strongly preferred by most study participants: “these results indicate that a category-based approach is a successful way to provide access to image collections.”17 in a related usability study on the flamenco interface, english et al. compared two image browsing interfaces in a nineteen-participant study.18 after an initial search, the “matrix view” interface showed a left column with facets, with the images in the result set placed in the main area of the screen. from this intermediary screen, the user could select multiple terms from facets in any order and have the items grouped under any facet. the “singletree” interface listed subcategories of the currently selected term at the top, with query previews underneath. the user could then only drill down to subcategories of the current category, and could not select terms from more than one facet. the researchers found that a majority of participants preferred the “power” and “flexibility” of matrix to the simplicity of singletree. they found it easier to refine and expand searches, shift between searches, and troubleshoot research problems. they did prefer singletree for locating a specific image, but matrix was preferred for browsing and exploring. participants started over only 0.2 percent of the time for the matrix compared to 4.5 percent for singletree.19 yet the faceted interface, matrix, was not “better” at everything. for specific image searching, participants found the correct image only 22.0 percent of the time in matrix compared to 66.0 percent in singletree.20 also, in matrix, some participants drilled down in the wrong hierarchy with wrong assumptions. one interesting finding was that in both interfaces, more participants chose to begin by browsing (12.7 percent) than by searching (5.0 percent).21 usability studies of faceted browsing: a literature review | fagan 61 of the first two studies: the first study comprised one faculty member, five graduate students, and two undergraduate students; the second comprised two faculty members, four graduate students, and two undergraduate students. the third study did not report results related to faceted browsing and is not discussed here. the first study had seven scenarios; the second study had nine. the scenarios were complex: for example, one scenario began, “you want to borrow shakespeare’s play, the tempest, from the library,” but contained the following subtasks as well: 1. find the tempest. 2. find multiple editions of this item. 3. find a recent version. 4. see if at least one of the editions is available in the library. 5. what is the call number of the book? 6. you’d like to print the details of this edition of the book so you can refer to it later. participants found the interface friendly, easy to use, and easy to learn. all the participants reported that faceted browsing was useful as a means of narrowing down the result lists, and they considered this tool one of the differentiating features between primo and their library opac or other interfaces. facets were clear, intuitive, and useful to all participants, including opening the “more” section.31 one specific result from the tests was that “online resources” and “available” limiters were moved from a separate location to the right with all other facets.32 in a study of aquabrowser by olson, twelve subjects— all graduate students in the humanities—participated in a comparative test in which they looked for additional sources for their dissertation.33 aquabrowser was created by medialab but is distributed by serials solutions in north america. this study also had three pilot subjects. no relevance judgments were made by the researchers. nine of the twelve subjects found relevant materials by using aquabrowser that they had not found before.34 olson’s subjects understood facets as a refinement tool (narrowing) and had a clear idea of which facets were useful and not useful for them. they gave overwhelmingly positive comments. only two felt the faceted interface was not an improvement. some participants wanted to limit to multiple languages or dates, and a few were confused about the location of facets in multiple places, for example, “music” under both format and topic. a team at yale university, led by bauer, recently conducted two tests on pilot vufind installations: a subject-based presentation of e-books for the cushing/ whitney medical library and a pilot test of vufind using undergraduate students with a sample of 400,000 records from the library system.35 vufind is open-source software developed at villanova university (http://vufind.org). that require users to understand and make sense of the information collection: “in which decade did steven spielberg direct the most movies?”). ■■ type 3: (one free exploration task: “find five favorite videos without any time constraints”). the tasks assigned for the two interfaces were different but comparable. for type 2 tasks, zhang and marchionini found that performance differences between the two interfaces were all statistically significant at the .05 level.28 no participants got wrong answers for any but one of the tasks using the faceted interface. with regard to satisfaction, on the exploratory tasks the researchers found statistically significant differences favoring the faceted interface on all three of the satisfaction questions. participants found the faceted interface not as aesthetically appealing nor as intuitive to use as the basic interface. two participants were confused by the constant changing and updating of the faceted interface. the above studies are examples of empirical investigations of experimental interfaces. hearst recently concluded that facets are a “proven technique for supporting exploration and discovery” and summarized areas for further research in this area, such as applying facets to large “subject-oriented category systems,” facets on mobile interfaces, adding smart features like “autocomplete” to facets, allowing keyword search terms to affect order of facets, and visualizations of facets.29 in the following section, user studies of next-generation library catalog interfaces will be presented. results: library literature understandably, most studies by practicing librarians focus on products their libraries are considering for eventual use. these studies all use real library catalog records, usually the entire catalog’s database. in most cases, these studies were not focused on investigating faceted browsing per se, but on the usability of the overall interface. in general, these studies used fewer participants than the information science studies above, followed less rigorous methods, and were not subjected to statistical tests. nevertheless, they provide many insights into the user experience with the extremely complex datasets underneath next-generation library catalog interfaces that feature faceted browsing. in this review article, only results specifically relating to faceted browsing will be presented. sadeh described a series of usability studies performed at the university of minnesota (um), a primo development partner.30 primo is the next-generation library catalog product sold by ex libris. the author also received additional information from the usability services lab at um via e-mail. three studies were conducted in august 2006, january 2007, and october 2007. eight users from various disciplines participated in each 62 information technology and libraries | june 2010 participants. the researchers measured task success, duration, and difficulty, but did not measure user satisfaction. their study consisted of four known-item tasks and six topic-searching tasks. the topic-searching tasks were geared toward the use of facets, for example, “can you show me how would you find the most recently published book about nuclear energy policy in the united states?”45 all five participants using endeca understood the idea of facets, and three used them. students tried to limit their searches at the outset rather than search and then refine results. an interesting finding was that use of the facets did not directly follow the order in which facets were listed. the most heavily used facet was library of congress classification (lcc), followed closely by topic, and then library, format, author, and genre.46 results showed a significantly shorter average task duration for endeca catalog users for most tasks.47 the researchers noted that none of the students understood that the lcc facet represented call-number ranges, but all of the students understood that these facets “could be used to learn about a topic from different aspects—science, medicine, education.”48 the authors could find no published studies relating to the use of facets in some next-generation library catalogs, including encore and worldcat local. although the university of washington did publish results of a worldcat local usability study in a recent issue of library technology reports, results from the second round of testing, which included an investigation of facets, were not yet ready.49 ■■ discussion summary of empirical evidence related to faceted browsing empirical studies in the information science literature support many positive findings related to faceted browsing and build a solid case for including facets in search interfaces: ■■ facets are useful for creating navigation structures.50 ■■ faceted categorization greatly facilitates efficient retrieval in database searching.51 ■■ facets help avoid dead ends.52 ■■ users are faster when using a faceted system.53 ■■ success in finding relevant results is higher with a faceted system.54 ■■ users find more results with a faceted system.55 ■■ users also seem to like facets, although they do not always immediately have a positive reaction. ■■ users prefer search results organized into predictable, multidimensional hierarchies.56 ■■ participants’ satisfaction is higher with a faceted system.57 the team drew test questions from user search logs in their current library system. some questions targeted specific problems, such as incomplete spellings and incomplete title information. bauer notes that some problems uncovered in the study may relate to the peculiarities of the yale implementation. the medical library study contained eight participants—a mix of medical and nursing students. facets, reported bauer, “worked well in several instances, although some participants did not think they were noticeable on the right side of the page.”36 the prompt for the faceted task in this study came after the user had done a search: “what if you wanted to look at a particular subset, say ‘xxx’ (determine by looking at the facets).”37 half of the participants used facets, half used “search within” to narrow the topic by adding keywords. sixty-two percent of the participants were successful at this task. the undergraduate study asked five participants faced with a results list, “what would you do now if you only wanted to see material written by john adams?”38 on this task, only one of the five was successful, even though the author’s name was on the screen. bauer noted that in general, “the use of the topic facet to narrow the search was not understood by most participants. . . . even when participants tried to use topic facets the length of the list and extraneous topics rendered them less than useful.”39 the five undergraduates were also asked, “could you find books in this set of results that are about health and illness in the united states population, or control of communicable diseases during the era of the depression?”40 again, only one of the five was successful. bauer notes that “the overly broad search results made this difficult for participants. again, topic facets were difficult to navigate and not particularly useful to this search.”41 bauer’s team noted that when the search was configured to return more hits, “topic facets become a confusingly large set of unrelated items. these imprecise search results, combined with poor topic facet sets, seemed to result in confusion for test participants.”42 participants were not aware that topics represented subsets, although learning occurred because the “narrow” header was helpful to some participants.43 other results found by bauer’s team were that participants were intrigued by facets, navigation tools are needed so that patrons may reorder large sets of topic facets, format and era facets were useful to participants, and call-number facets were not used by anyone. antelman, pace, and lynema studied north carolina state university’s (ncsu) next-generation library catalog, which is driven by software from endeca.44 their study used ten undergraduate students in a between-subjects design where five used the endeca catalog and five used the library’s traditional catalog. the researchers noted that their participants may have been experienced with the library’s old catalog, as log data shows most ncsu users enter one or two terms, which was not true of study usability studies of faceted browsing: a literature review | fagan 63 one product’s faceted system for a library catalog does not substitute for another, the size and scope of local collections may greatly affect results, and cataloging practices and metadata will affect results. still, it is important for practicing librarians to determine if new features such as facets truly improve the user’s experience. methodological best practices after reading numerous empirical research studies (some of which critique their own methods) and library case studies, some suggestions for designing better studies of facets in library catalogs emerged. designing the study ■■ consider reusing protocols from previous studies. this provides not only a tested method but also a possible point of comparison. ■■ define clear goals for each study and focus on specific research questions. it’s tempting to just throw the user into the interface and see what happens, but this makes it difficult, if not impossible, to analyze the results in a useful way. for example, one of zhang and marchionini’s hypotheses specifically describes what rich interaction would look like: “typing in keywords and clicking visual bars to filter results would be used frequently and interchangeably by the users to finish complex search tasks, especially when large numbers of results are returned.”64 ■■ develop the study for one type of user. olson’s focus on graduate students in the dissertation process allowed the researchers to control for variables such as interest of and knowledge about the subject. ■■ pilot test the study with a student worker or colleague to iron out potential wrinkles. ■■ let users explore the system for a short time and possibly complete one highly structured task to help the user become used to the test environment, interface, and facilitator.65 unless you are truly interested in the very first experience users have with a system, the first use of a system is an artificial case. designing tasks ■■ make sure user performance on each task is measurable. will you measure the time spent on a task? if “success” is important, define what that would look like. for example, english et al. defined success for one of their tasks as when “the participant indicated (within the allotted time) that he/she had reached an appropriate set of images/specific image in the collection.”66 ■■ establish benchmarks for comparison. one can test for significant differences between interfaces, one can test for differences between research subjects and an expert user, and one can simply measure against ■■ users are more confident with a faceted system.58 ■■ users may prefer the familiarity afforded by traditional website interface (hyperlinks + keyword search).59 ■■ initial reactions to the faceted interface may be cautious, seeing it as different or unfamiliar.60 users interact with specific characteristics of faceted interfaces, and they go beyond just one click with facets when it is permitted. english et al. found that 7 percent of their participants expanded facets by removing a term, and that facets were used more than “keyword search within”: 27.6 percent versus 9 percent.61 yee et al. found that participants construct queries from multiple facets 19 percent of the time in unstructured tasks; in structured tasks they do so 45 percent of the time.62 the above studies did not use library catalogs; in most cases they used an experimental interface with record sets that were much smaller and less complicated than in a complete library collection. domains included websites, information from one website, image collections, video collections, and a journal article collection. summary of practical user studies related to faceted browsing this review also included studies from practicing librarians at live library implementations. these studies generally had smaller numbers of users, were more likely to focus on the entire interface rather than a few features, and chose more widely divergent methods. studies were usually linked to a specific product, and results varied widely between systems and studies. for this reason it is difficult to assemble a bulleted summary as with the previous section. the variety of results from these studies indicate that when faceted browsing is applied to a reallife situation, implementation details can greatly affect user performance and user preference. some, like labarre, are skeptical about whether facets are appropriate for library information. descriptions of library materials, says labarre, include analyses of intellectual content that go beyond the descriptive terms assigned to commercial items such as a laptop: now is the time to question the assumptions that are embedded in these commercial systems that were primarily designed to provide access to concrete items through descriptions in order to enhance profit.63 it is clear that an evaluation of commercial interfaces or experimental interfaces does not substitute for an opac evaluation. yet it is a challenge for libraries to find expertise and resources to conduct user studies. the systems they want to test are large and complex. collaborating with other libraries has its own challenges: an evaluation of 64 information technology and libraries | june 2010 groups of participants, each of which tests a different system. ■❏ a within-subjects design has one group of participants test both systems. it is hoped that if libraries use the suggestions above when designing future experiments, results across studies will be more comparable and useful. designing user studies of faceted browsing after examining both empirical research studies and case studies by practicing librarians, a key difference seems to be the specificity of research questions and designing tasks and measurements to test specific hypotheses. while describing a full user-study protocol for investigating faceted browsing in a library catalog is beyond the scope of this article, reviewing the literature and the study methods it describes provided insights into how hypotheses, tasks, and measurements could be written to provide more reliable and comparable evidence related to faceted browsing in library catalog systems. for example, one research question could surround the format facet: “compared with our current interface, does our new faceted interface improve the user’s ability to find different formats of materials?” hypotheses could include the following: 1. users will be more accurate when identifying the formats of items from their result set when using the faceted interface than when using the traditional interface. 2. users will be able to identify formats of items more quickly with the faceted interface than with the traditional interface. looking at these hypotheses, here is a prompt and some example tasks the participants would be asked to perform: “we will be asking you to find a variety of formats of materials. when we say formats of materials, we mean books, journal articles, videos, etc.” ■■ task 1: please use interface a to search on “interpersonal communication.” look at your results set. please list as many different formats of material as you can. ■■ task 2: how many items of each format are there? ■■ task 3: please use interface b to search on “family communication.” what formats of materials do you see in your results set? ■■ task 4: how many items of each format are there?” we would choose the topics “interpersonal communication” and “family communication” because our local catalog has many material types for these topics and because these topics would be understood by most of our students. we would choose different topics to expectations or against previous iterations of the same study. for example, “75 percent of users completed the task within five minutes.” zhang and marchionini measured error rates, another possible benchmark.67 ■■ consider looking at your existing opac logs for zeroresults searches or other issues that might inspire interesting questions. ■■ target tasks to avoid distracters. for example, if your catalog has a glut of government documents, consider running the test with a limit set to exclude them unless you are specifically interested in their impact. for example, capra et al. decided to include the united states as a geographic facet and a month or year as a temporal facet to provide context for all search tasks in their study.68 ■■ for some tasks, give the subjects simple queries (e.g., “what are the ways to prevent breast cancer?”) as opposed to asking the subjects to come up with their own topic. this can help control for the potential challenges of formulating one’s own research question on the spot. as librarians know, formulating a good research question is its own challenge. ■■ if you are using any timed tasks, consider how the nature of your tasks could affect the result. for example, pratt, hearst, and fagan noted that the time that it took subjects to read and understand abstracts most heavily influenced the time for them to find an answer.69 english et al. found that the system’s processing time influenced their results.70 ■■ consider the implications of your local implementation carefully when designing your study. at yale, the team chose to point their vufind instance at just 400,000 of their records, drew questions from problems users were having (as shown in log files), and targeted questions to these problems.71 who to study? ■■ try to study a larger set of users. it is better to create a short test with many users than a long test with a few users. nielsen suggests that twenty users is sufficient.72 consider collaborating with another library if necessary. ■■ if you test a small number, such as the typical four to eight users for a usability test, be sure you emphasize that your results are not generalizable. ■■ use subjects who are already interested in the subject domain: for example, pratt, hearst, and fagan used breast cancer patients,73 and olson used graduate students currently writing their dissertations.74 ■■ consider focusing on advanced or scholarly users. la barre suggests that undergraduates may be overstudied.75 ■■ for comparative studies, consider having both between-subjects and within-subjects designs.76 ■❏ a between-subjects design involves creating two usability studies of faceted browsing: a literature review | fagan 65 these experimental studies. previous case-study investigations of library catalog interfaces with facets have proven inconclusive. by choosing more specific research questions, tasks, and measurements for user studies, libraries may be able to design more objective studies and compare results more effectively. references 1. marti a. hearst, “clustering versus faceted categories for information exploration,” communications of the acm 49, no. 4 (2006): 60. 2. kathryn la

users start first with the traditional interface and half to start first with the faceted interface. this way we can test for differences resulting from learning. the above tasks would allow us to measure several pieces of evidence to support or reject our hypotheses. for tasks 1 and 3, we would measure the number of formats correctly identified by users compared with the number found by an expert searcher. for tasks 2 and 4, we would compare the number of items correctly identified with the total items found in each category by an expert searcher. we could also time the user to determine which interface helped them work more quickly. in addition to measuring the number of formats identified and the number of items identified in each format, we would be able to measure the time it takes users to identify the number of formats and the number of items in each format. to measure user satisfaction, we would ask participants to complete the system usability scale (sus) after each interface and, at the very end of the study, complete a questionnaire comparing the two interfaces. even just selecting the format facet, we would have plenty to investigate. other hypotheses and tasks could be developed for other facet types, such as time period or publication date, or facets related to the responsible parties, such as author or director: hypothesis: users can find more materials written in a certain time period using the faceted interface. task: find ten items of any type (books, journals, movies) written in the 1950s that you think would have information about television advertising. hypothesis: users can find movies directed by a specific person more quickly using the faceted interface. task: in the next two minutes, find as many movies as you can that were directed by orson welles. for the first task above, an expert searcher could complete the same task, and their time could be used as a point of comparison. for the second, the total number of movies in the library catalog that were directed by welles is an objective quantity. in both cases, one could compare the user’s performance on the two interfaces. ■■ conclusion reviewing user studies about faceted browsing revealed empirical evidence that faceted browsing improves user performance. yet this evidence does not necessarily point directly to user success in faceted library catalogs, which have much more complex databases than those used in 66 information technology and libraries | june 2010 53. uddin and janecek, “performance and usability testing”; zhang and marchionini,

 a  couple  of  technical  hiccups  related  to  the  publication   of  back  issues  of  ital  previously  only  available  in  print:  the  publication  system  we’re  using  (open   journal

shelton’s managing public computing, which confirmed the lack of applicable guidelines on academic websites, had more up-to-date information but was not available to the researchers at the time the project was initiated.2 in the course of research, the authors developed the following questions: ■■ how many arl libraries require affiliated users to log into public computer workstations within the library? ■■ how many arl libraries provide the means to authenticate guest users and allow them to log on to the same computers used by affiliates? ■■ how many arl libraries offer open-access computers for guests to use? do these libraries provide both open-access computers and the means for guest user authentication? ■■ how do federal depository library program libraries balance their policy requiring computer authentication with the obligation to provide public access to government information? ■■ do computers provided for guest use (open access or guest login) provide different software or capabilities than those provided to affiliated users? ■■ how many arl libraries have written policies for the use of open-access computers? if a policy exists, what is it? ■■ how many arl libraries have written policies for authenticating guest users? if a policy exists, what is it? ■■ literature review since the 1950s there has been considerable discussion within library literature about academic libraries serving “external,” “secondary,” or “outside” users. the subject has been approached from the viewpoint of access to the library facility and collections, reference assistance, interlibrary loan (ill) service, borrowing privileges, and (more recently) access to computers and internet privileges, including the use of proprietary databases. deale emphasized the importance of public relations to the academic library.3 while he touched on creating bonds both on and off campus, he described the positive effect of “privilege cards” to community members.4 josey described the variety of services that savannah state college offered to the community.5 he concluded his essay with these words: why cannot these tried methods of lending books to citizens of the community, story hours for children . . . , a library lecture series or other forum, a great books discussion group and the use of the library staff in the fall of 2004, the academic computing center, a division of the information technology services department (its) at minnesota state university, mankato took over responsibility for the computers in the public areas of memorial library. for the first time, affiliated memorial library users were required to authenticate using a campus username and password, a change that effectively eliminated computer access for anyone not part of the university community. this posed a dilemma for the librarians. because of its federal depository status, the library had a responsibility to provide general access to both print and online government publications for the general public. furthermore, the library had a long tradition of providing guest access to most library resources, and there was reluctance to abandon the practice. therefore the librarians worked with its to retain a small group of six computers that did not require authentication and were clearly marked for community use, along with several standup, open-access computers on each floor used primarily for searching the library catalog. the additional need to provide computer access to high school students visiting the library for research and instruction led to more discussions with its and resulted in a means of generating temporary usernames and passwords through a web form. these user accommodations were implemented in the library without creating a written policy governing the use of open-access computers. o ver time, library staff realized that guidelines for guests using the computers were needed because of misuse of the open-access computers. we were charged with the task of drafting these guidelines. in typical librarian fashion, we searched websites, including those of association of research libraries (arl) members for existing computer access policies in academic libraries. we obtained very little information through this search, so we turned to arl publications for assistance. library public access workstation authentication by lori driscoll, was of greater benefit and offered much of the needed information, but it was dated.1 a research result described lynne webber (lnweber@mnsu.edu) is access services librarian and peg lawrence (peg.lawrence@mnsu.edu) is systems librarian, minnesota state university, mankato. authentication and access | weber and lawrence 129 providing service to the unaffiliated, his survey revealed 100 percent of responding libraries offered free in-house collection use for the general public, and many others offered additional services.16 brenda johnson described a one-day program in 1984 sponsored by rutgers university libraries forum titled “a case study in closing the university library to the public.” the participating librarians spent the day familiarizing themselves with the “facts” of the theoretical case and concluded that public access should be restricted but not completely eliminated. a few months later, consideration of closing rutgers’ library to the public became a real debate. although there were strong opposing viewpoints, the recommendation was to retain the open-door policy.17 jansen discussed the division between those who wanted to provide the finest service to primary users and those who viewed the library’s mission as including all who requested assistance. jansen suggested specific ways to balance the needs of affiliates and the public and referred to the dilemma the university of california, berkeley, library that had been closed to unaffiliated users.18 bobp and richey determined that california undergraduate libraries were emphasizing service to primary users at a time when it was no longer practical to offer the same level of service to primary and secondary users. they presented three courses of action: adherence to the status quo, adoption of a policy restricting access, or implementation of tiered service.19 throughout the 1990s, the debate over the public’s right to use academic libraries continued, with increasing focus on computer use in public and private academic libraries. new authorization and authentication requirements increased the control of internal computers, but the question remained of libraries providing access to government information and responding to community members who expected to use the libraries supported by their taxes. morgan, who described himself as one who had spent his career encouraging equal access to information, concluded that it would be necessary to use authentication, authorization, and access control to continue offering information services readily available in the past.20 martin acknowledged that library use was changing as a result of the internet and that the public viewed the academic librarian as one who could deal with the explosion of information and offer service to the public.21 johnson described unaffiliated users as a group who wanted all the privileges of the affiliates; she discussed the obligation of the institution to develop policies managing these guest users.22 still and kassabian considered the dual responsibilities of the academic library to offer internet access to public users and to control internet material received and sent by primary and public users. further, they weighed as consultants be employed toward the building of good relations between town and gown.6 later, however, deale indicated that the generosity common in the 1950s to outsiders was becoming unsustainable.7 deale used beloit college, with an “open door policy” extending more than 100 years, as an example of a school that had found it necessary to refuse out-of-library circulation to minors except through ill by the 1960s.8 also in 1964, waggoner related the increasing difficulty of accommodating public use of the academic library. he encouraged a balance of responsibility to the public with the institution’s foremost obligation to the students and faculty.9 in october 1965, the ad hoc committee on community use of academic libraries was formed by the college library section of the association of college and research libraries (acrl). this committee distributed a 13-question survey to 1,100 colleges and universities throughout the united states. the high rate of response (71 percent) was considered noteworthy, and the findings were explored in “community use of academic libraries: a symposium,” published in 1967.10 the concluding article by josey (the symposium’s moderator) summarized the lenient attitudes of academic libraries toward public users revealed through survey and symposium reports. in the same article, josey followed up with his own arguments in favor of the public’s right to use academic libraries because of the state and federal support provided to those institutions.11 similarly, in 1976 tolliver reported the results of a survey of 28 wisconsin libraries (public academic, private academic, and public), which indicated that respondents made a great effort to serve all patrons seeking service.12 tolliver continued in a different vein from josey, however, by reporting the current annual fiscal support for libraries in wisconsin and commenting upon financial stewardship. tolliver concluded by asking, “how effective are our library systems and cooperative affiliations in meeting the information needs of the citizens of wisconsin?”13 much of the literature in the years following focused on serving unaffiliated users at a time when public and academic libraries suffered the strain of overuse and underfunding. the need for prioritization of primary users was discussed. in 1979, russell asked, “who are our legitimate clientele?” and countered the argument for publicly supported libraries serving the entire public by saying the public “cannot freely use the university lawn mowers, motor pool vehicles, computer center, or athletic facilities.”14 ten years later, russell, robison, and prather prefaced their report on a survey of policies and services for outside users at 12 consortia institutions by saying, “the issue of external users is of mounting concern to an institution whose income is student credit hour generated.”15 despite russell’s concerns about the strain of 130 information technology and libraries | september 2010 be aware of the issues and of the effects that licensing, networking, and collection development decisions have on access.”35 in “unaffiliated users’ access to academic libraries: a survey,” courtney reported and analyzed data from her own comprehensive survey sent to 814 academic libraries in winter 2001.36 of the 527 libraries responding to the survey, 72 libraries (13.6 percent) required all users to authenticate to use computers within the library, while 56 (12.4 percent) indicated that they planned to require authentication in the next twelve months.37 courtney followed this with data from surveyed libraries that had canceled “most” of their indexes and abstracts (179 libraries, or 33.9 percent) and libraries that had cancelled “most” periodicals (46 libraries or 8.7 percent).38 she concluded that the extent to which the authentication requirement restricted unaffiliated users was not clear, and she asked, “as greater numbers of resources shift to electronic-only formats, is it desirable that they disappear from the view of the community user or the visiting scholar?”39 courtney’s “authentication and library public access computers: a call for discussion” described a follow-up with the academic libraries participating in her 2001 survey who had self-identified as using authentication or planning to employ authentication within the next twelve months. her conclusion was the existence of ambivalence toward authentication among the libraries, since more than half of the respondents provided some sort of public access. she encouraged librarians to carefully consider the library’s commitment to service before entering into blanket license agreements with vendors or agreeing to campus computer restrictions.40 several editions of the arl spec kit series showing trends of authentication and authorization for all users of arl libraries have been an invaluable resource in this investigation. an examination of earlier spec kits indicated that the definitions of “user authentication” and “authorization” have changed over the years. user authentication, by plum and bleiler indicated that 98 percent of surveyed libraries authenticated users in some way, but at that time authentication would have been more precisely defined as authorization or permission to access personal records, such as circulation, e-mail, course registration, and file space. as such, neither authentication nor authorization was related to basic computer access.41 by contrast, it is common for current library users authenticate to have any access to a public workstation. driscoll’s library public access workstation authentication sought information on how and why users were authenticated on public-access computers, who was driving the change, how it affected the ability of federal depository libraries to provide public information, and how it affected library services in general.42 but at the time of driscoll’s survey, only 11 percent of surveyed libraries required authentication on all computers and 22 percent required it only on selected terminals. cook and shelton’s managing public computing the reconciliation of material restrictions against “principles of freedom of speech, academic freedom, and the ala’s condemnation of censorship.”23 lynch discussed institutional use of authentication and authorization and the growing difficulty of verifying bona fide users of academic library subscription databases and other electronic resources. he cautioned that future technical design choices must reflect basic library values of free speech, personal confidentiality, and trust between academic institution and publisher.24 barsun specifically examined the webpages of one hundred arl libraries in search of information pertinent to unaffiliated users. she included a historic overview of the changing attitudes of academics toward service to the unaffiliated population and described the difficult balance of college community needs with those of outsiders in 2000 (the survey year).25 barsun observed a consistent lack of information on library websites regarding library guest use of proprietary databases.26 carlson discussed academic librarians’ concerns about “internet-related crimes and hacking” leading to reconsideration of open computer use, and he described the need to compromise patron privacy by requiring authentication.27 in a chapter on the relationship of it security to academic values, oblinger said, “one possible interpretation of intellectual freedom is that individuals have the right to open and unfiltered access to the internet.”28 this statement was followed later with “equal access to information can also be seen as a logical extension of fairness.”29 a short article in library and information update alerted the authors to a uk project investigating improved online access to resources for library visitors not affiliated with the host institution.30 salotti described higher education access to e-resources in visited institutions (haervi) and its development of a toolkit to assist with the complexities of offering electronic resources to guest users.31 salotti summarized existing resources for sharing within the united kingdom and emphasized that “no single solution is likely to suit all universities and colleges, so we hope that the toolkit will offer a number of options.”32 launched by the society of college, national and university libraries (sconul), and universities and colleges information systems association (ucisa), haervi has created a best-practice guide.33 by far the most useful articles for this investigation have been those by nancy courtney. “barbarians at the gates: a half-century of unaffiliated users in academic libraries,” a literature review on the topic of visitors in academic libraries, included a summary of trends in attitude and practice toward visiting users since the 1950s.34 the article concluded with a warning: “the shift from printed to electronic formats . . . combined with the integration of library resources with campus computer networks and the internet poses a distinct threat to the public’s access to information even onsite. it is incumbent upon academic librarians to authentication and

of the 117 arl libraries invited to participate in the survey responded. this is comparable with the response rate for similar surveys reported by plum and bleiler (52 of 121, or 43 percent), driscoll

library? see figure 4. this question caused some confusion for the canadian survey respondents because canada has its own depository services program corresponding to the u.s. federal depository program. consequently, 57 of the 61 respondents identified themselves as federal depository (including three canadian libraries), although 5 of the 61 are more accurately members of the canadian depository services program. only two responding libraries were neither a member of the u.s. federal depository program nor of the canadian depository services program. 6. if you answered “yes” to the

touched on every aspect of managing public computing, including public computer use, policy, and security.43 even in 2007, only 25 percent of surveyed libraries required authentication on all computers, but 46 percent required authentication on some computers, showing the trend toward an ever increasing number of libraries requiring public workstation authentication. most of the responding libraries had a computer-use policy, with 48 percent following an institution-wide policy developed by the university or central it department.44 ■■ method we constructed a survey designed to obtain current data about authentication in arl libraries and to provide insight into how guest access is granted at various academic institutions. it should be noted that the object of the survey was access to computers located in the public areas of the library for use by patrons, not access to staff computers. we constructed a simple, fourteen-question survey using the zoomerang online tool (http://www .zoomerang.com/). a list of the deans, directors, and chief operating officers from the 123 arl libraries was compiled from an internet search. we eliminated the few library administrators whose addresses could not be readily found and sent the survey to 117 individuals with the request that it be forwarded to the appropriate respondent. the recipients were informed that the goal of the project was “determination of computer authentication and current computer access practices within arl libraries” and that the intention was “to reflect practices at the main or central library” on the respondent’s campus. recipients were further informed that the names of the participating libraries and the responses would be reported in the findings, but that there would be no link between responses given and the name of the participating library. the survey introduction included the name and contact information of the institutional review board administrator for minnesota state university, mankato. potential respondents were advised that the e-mail served as informed consent for the study. the survey was administered over approximately three weeks. we sent reminders three, five, and seven days after the survey was launched to those who had not already responded. ■■ survey questions, responses, and findings we administered the survey, titled “authentication and access:

authentication practices of public, private, and other institutions described in response to question 2. responses from public institutions outnumbered those from private institutions, but within each group a similar percentage of libraries required their affiliated users to authenticate. therefore no statistically significant difference was found between authenticating affiliates in public and private institutions. of the 61 respondents, 32 (52 percent) required their affiliated users to authenticate (see question 3) and 23 of the 32 also had the means to authenticate guests (see question 4). the remaining 9 offered open-access computers. fourteen libraries had both the means to authenticate guests and had open-access computers (see questions 4 and 7). when we compare the results of the 2007 study by cook and shelton with the results of the current study (completed in 2008), the results are somewhat contradictory (see table 1).46 the differences in survey data seem to indicate that authentication requirements are decreasing; however, the literature review—specifically cook and shelton and the 2003 courtney article—clearly indicate that authentication is on the rise.47 this dichotomy may be explained, in part, by the fact that of the more than 60 arl libraries responding to both surveys, there was an overlap of only 34 libraries. the 30 u.s. federal depository or canadian depository services libraries that required their affiliated users to authenticate (see questions 3 and 5) provided guest access ranging from usernames and passwords, to open-access computers, to computers restricted to libraries gave the url to their policy; 4 summarized their policies. ■■ research questions answered the study resulted in answers to the questions we posed at the outset: ■■ thirty-two (52 percent) of the responding arl libraries required affiliated users to login to public computer workstations in the library. ■■ twenty-three (72 percent) of the 32 arl libraries requiring affiliated users to login to public computers provided the means for guest users to login to public computer workstations in the library. ■■ fifty (82 percent) of 61 responding arl libraries provided open-access computers for guest users; 14 (28 percent) of those 50 libraries provided both open-access computers and the means for guest authentication. ■■ without exception, all u.s. federal depository or canadian depository services libraries that required their users to authenticate offered guest users some form of access to online information. ■■ survey results indicated some differences between software provided to various users on differently accessed computers. office software was less frequently provided on open-access computers. ■■ twenty-eight responding arl libraries had written policies relating to the use of open-access computers. ■■ fifteen responding arl libraries had written policies relating to the authorization of guests. figure 9. electronic resources on open access computers (n = 50) figure 10. comparison of library type and authentication requirement number of libraries authentication and access | weber and lawrence 135 ■■ one library had guidelines for use posted next to the workstations but did not give specifics. ■■ fourteen of those requiring their users to authenticate had both open-access computers and guest authentication to offer to visitors of their libraries. other policy information was obtained by an examination of the 28 websites listed by respondents: ■■ ten of the sites specifically stated that the open-access computers were for academic use only. ■■ five of the sites specified time limits for use of openaccess computers, ranging from 30 to 90 minutes. ■■ four stated that time limits would be enforced when others were waiting to use computers. ■■ one library used a sign-in sheet to monitor time limits. ■■ one library mentioned a reservation system to monitor time limits. ■■ two libraries prohibited online gambling. ■■ six libraries prohibited viewing sexually explicit materials. ■■ guest-authentication policies of the 23 libraries that had the means to authenticate their guests, 15 had a policy for guests obtaining a username and password to authenticate, and 6 outlined their requirements of showing identification and issuing access. the other 9 had open-access computers that guests might use. the following are some of the varied approaches to guest authentication: ■■ duration of the access (when mentioned) ranged from 30 days to 12 months. ■■ one library had a form of sponsored access where current faculty or staff could grant a temporary username and password to a visitor. ■■ one library had an online vouching system that allowed the visitor to issue his or her own username and password online. ■■ one library allowed guests to register themselves by swiping an id or credit card. ■■ one library had open-access computers for local resources and only required authentication to leave the library domain. ■■ one library had the librarians log the users in as guests. ■■ one library described the privacy protection of collected personal information. ■■ no library mentioned charging a fee for allowing computer access. government documents, to librarians logging in for guests (see question 6). numbers of open-access computers ranged widely from 2 to more than 3,000 (see question 7). eleven (19 percent) of the responding u.s. federal depository or canadian depository services libraries that did not provide open-access computers issued a temporary id (nine libraries), provided open access limited to government documents (one library), or required librarian login for each guest (one library). all libraries with u.s. federal depository or canadian depository services status provided a means of public access to information to fulfill their obligation to offer government documents to guests. figure 11 shows a comparison of resources available to authenticated users and authenticated guests and offered on open-access computers. as might be expected, almost all institutions provided access to online catalogs, government documents, and internet browsers. fewer allowed access to licensed electronic resources and e-mail. access to office software showed the most dramatic drop in availability, especially on open-access computers. ■■ open-access computer policies as mentioned earlier, 28 libraries had written policies for their open-access computers (see question 11), and 28 libraries gave a url, a url plus a summary explanation, or a summary explanation with no url (see question 12). in most instances, the library policy included their campus’s acceptable-use policy. seven libraries cited their campus’s acceptable-use policy and nothing else. nearly all libraries applied the same acceptable-use policy to all users on all computers and made no distinction between policies for use of open-access computers or computers requiring authentication. following are some of the varied aspects of summarized policies pertaining to open-access computers: ■■ eight libraries stated that the computers were for academic use and that users might be asked to give up their workstation if others were waiting. table 1. comparison of findings from cook and shelton (2007) and the current survey (2008) authentication requirements 2007 (n = 69) 2008 (n = 61) some required 28 (46%) 23 (38%) required for all 15 (25%) 9 (15%) not required 18 (30%) 29 (48%) 136 information technology and libraries | september 2010 ■■ further study although the survey answered many of our questions, other questions arose. while the number of libraries requiring affiliated users to log on to their public computers is increasing, this study does not explain why this is the case. reasons could include reactions to the september 11 disaster, the usa patriot act, general security concerns, or the convenience of the personalized desktop and services for each authenticated user. perhaps a future investigation could focus on reasons for more frequent requirement of authentication. other subjects that arose in the examination of institutional policies were guest fees for services, age limits for younger users, computer time limits for guests, and collaboration between academic and public libraries. ■■ policy developed as a result of the survey findings as a result of what was learned in the survey, we drafted guidelines governing the use of open-access computers by visitors and other non-university users. the guidelines can be found at http://lib.mnsu.edu/about/libvisitors .html#access. these guidelines inform guests that openaccess computers are available to support their research, study, and professional activities. the computers also are governed by the campus policy and the state university system acceptable-use policy. guideline provisions enable staff to ask users to relinquish a computer when others are waiting or if the computer is not being used for academic purposes. while this library has the ability to generate temporary usernames and passwords, and does so for local schools coming to the library for research, no guidelines have yet been put in place for this function. figure 11. online resources available to authenticated affiliated users, guest users, open-access users authentication and access | weber and lawrence 137 these practices depend on institutional missions and goals and are limited by reasonable considerations. in the past, accommodation at some level was generally offered to the community, but the complications of affiliate authentication, guest registration, and vendor-license restrictions may effectively discourage or prevent outside users from accessing principal resources. on the other hand, open-access computers facilitate access to electronic resources. those librarians who wish to provide the same level of commitment to guest users as in the past as well as protect the rights of all should advocate to campus policy-makers at every level to allow appropriate guest access to computers to fulfill the library’s mission. in this way, the needs and rights of guest users can be balanced with the responsibilities of using campus computers. in addition, librarians should consider ensuring that the licenses of all electronic resources accommodate walk-in users and developing guidelines to prevent incorporation of electronic materials that restrict such use. this is essential if the library tradition of freedom of access to information is to continue. finally, in regard to external or guest users, academic librarians are pulled in two directions; they are torn between serving primary users and fulfilling the principles of intellectual freedom and free, universal access to information along with their obligations as federal depository libraries. at the same time, academic librarians frequently struggle with the goals of the campus administration responsible for providing secure, reliable networks, sometimes at the expense of the needs of the outside community. the data gathered in this study, indicating that 82 percent of responding libraries continue to provide at least some open-access computers, is encouraging news for guest users. balancing public access and privacy with institutional security, while a current concern, may be resolved in the way of so many earlier preoccupations of the electronic age. given the pervasiveness of the problem, however, fair and equitable treatment of all library users may continue to be a central concern for academic libraries for years to come. references 1. lori driscoll, library public access workstation authentication, spec kit 277 (washington, d.c.: association of research libraries,

■■ conclusions while we were able to gather more than 50 years of literature pertaining to unaffiliated users in academic libraries, it soon became apparent that the scope of consideration changed radically through the years. in the early years, there was discussion about the obligation to provide service and access for the community balanced with the challenge to serve two clienteles. despite lengthy debate, there was little exception to offering the community some level of service within academic libraries. early preoccupation with physical access, material loans, ill, basic reference, and other services later became a discussion of the right to use computers, electronic resources, and other services without imposing undue difficulty to the guest. current discussions related to guest users reflect obvious changes in public computer administration over the years. authentication presently is used at a more fundamental level than in earlier years. in many libraries, users must be authorized to use the computer in any way whatsoever. as more and more institutions require authentication for their primary users, accommodation must be made if guests are to continue being served. in addition, as courtney’s 2003 research indicates, an ever increasing number of electronic databases, indexes, and journals replace print resources in library collections. this multiplies the roadblocks for guest users and exacerbates the issue.48 unless special provisions are made for computer access, community users are left without access to a major part of the library’s collections. because 104 of the 123 arl libraries (85 percent) are federal depository or canadian depository services libraries, the researchers hypothesized that most libraries responding to the survey would offer open-access computers for the use of nonaffiliated patrons. this study has shown that federal depository libraries have remained true to their mission and obligation of providing public access to government-generated documents. every federal depository respondent indicated that some means was in place to continue providing visitor and guest access to the majority of their electronic resources— whether through open-access computers, temporary or guest logins, or even librarians logging on for users. while access to government resources is required for the libraries housing government-document collections, libraries can use considerably more discretion when considering what other resources guest patrons may use. despite the commitment of libraries to the dissemination of government documents, the increasing use of authentication may ultimately diminish the libraries’ ability and desire to accommodate the information needs of the public. this survey has provided insight into the various ways academic libraries serve guest users. not all academic libraries provide public access to all library resources. 138 information technology and libraries | september 2010

know whence they will come? a s i write this, i am putting my affairs in order at western michigan university, in preparation for a move to a new position at the university of notre dame libraries beginning in april. at each university my responsibilities include overseeing both the online catalog and the libraries' web presence. i mention this only because i find it interesting, and indicative of an issue with which the library profession in general is grappling, that librarians in both institutions are engaged in discussions regarding the relationship between the two. in talking to librarians at those places and others, from some i hear sentiment for making one or the other the "primary" access point. thus i've heard arguments that "the online catalog represents our collection, so we should use it as our main access mechanism." other librarians state that "the online catalog is fine for searching for books in our collection, but there is so much more to find and so many more options for finding it, that we should use our web pages to link everything together." my hunch is that probably we can all agree that there are things that an online catalog can do better than a web site, and things that a web site can do better than the online catalog. as far as that goes, have we ever had a primary access point (thanks to karen coyle for this thought)? but that's not what i want to talk about today. the debate over a primary access point contains an invalid implicit assumption and asks the wrong question. the implicit assumption is that we can and should control how our patrons come into our systems. the question we should be asking ourselves is not "what is our primary access method?" but rather "how can we ensure that our users, local and remote, will find an avenue that enables them to meet their informational needs?" since at this time i'm more familiar with wmu than notre dame, i'll draw some examples from the former. we have "subject guides to resources" on our web site. these consist of pages put together by subject specialists that point to recommended sources, both print and electronic, dan marmion local and remote, on given subjects. students can use them to begin researching topics in a large number of subject areas. the catch is that the students have to be browsing around the web site. if they happen to start out in the online catalog they will never encounter these gateways, because the only reference to them is on the web site. on the other hand, a student who stays strictly with the web site is quite possibly going to miss a valuable resource in our library if he/she doesn't consult the online catalog, because we obviously can't list everything we own on the web site. (also, obviously, the web site doesn't provide the patron with status information.) this is why we have to ask ourselves the correct question mentioned above. what is the solution? unfortunately i'm not any smarter than everyone else, so i don't have the answer (although i do know some folks who can help us with it: check out www.lita.org/ committe / toptech/ main page. htm). my guess is that we'll have to work it out as a profession, possibly in collaboration with our online system vendors, and that the solution will be neither quick nor simple nor easy. there are some ad hoc moves we can make, of course, such as put links to the gateways into the catalog, and on our web pages stress that the patron really needs to do a catalog search. the bottom line is that we have a dilemma: we can't control how people come into our electronic systems, so we can't have a "primary access point." if we try, we do harm to those who, for whatever reason, reach us via some other avenue. we need to make sure that we provide equal opportunity for all. dan marmion (dmarmion@nd.edu) is associate director of information systems and access at notre dame university, notre dame, indiana. production: ala production services (troy d. linker, christine s. taylor; angela hanshaw, kevin heubusch, and tracy malecki), american library association, 50 e. huron st., chicago, il 60611. publication of material in information technologtj and libraries does not constitute official endorsement by lita or the ala. abstracted in computer & information systems, computing reviews, information science abstracts, library & information science abstracts, referativnyi zhurnal, nauclmaya i tekhnicheskaya informatsiya, otdyelnyi vypusk, and science abstracts publications. indexed in compumath citation index, computer contents, computer literature index, current contents/health services administration, current contents/social behavioral sciences, current index to journals in education, education, library literature, magazine index, newsearch, and social sciences citation index. microfilm copies available to subscribers from university microfilms, ann arbor, michigan. mum requirements of american national standard for information sciences-permanence of paper for printed library materials, ansi z39.48-1992.oo copyright ©2000 american library association. all material in this journal subject to copyright by ala may be photocopied for the noncommercial purpose of scientific or educational advancement granted by sections 107 and 108 of the copyright revision act of 1976. for other reprinting, photocopying, or translating, address requests to the ala office of rights and permissions. the paper used in this publication meets the minieditorial i 3 315 technical communications isad/solinet to sponsor institute "networks and networking ii; the present and potential" is the theme of an isad institute to be held at the braniff place hotel on february 27-28, 1975, in new orleans. the sponsors are the information science and automation division of ala and the southeastern library network (solinet). this second institute on networking will be an extension of the previous one held in new orleans a year ago. the ground covered in that previous institute will be the point of departure for "networks ii." the purpose of the previous institute was to review the options available in networking, to provide a framework for identifying problems, and to suggest evaluation strategies to aid in choosing alternative systems. while the topics covered in the previous institute will be briefly reviewed in this one, some speakers will take different approaches to the subject of networking, while other speakers will discuss totally new aspects. in addition to the papers given and the resultant questions and answers from the floor, a period of round table discussions will be held during which the speakers can be questioned on a person-to-person basis. a new feature to isad institutes now being planned will be the presence of vendors' exhibits. arrangements are being made with the many vendors and manufacturers whose services are applicable to networking to exhibit their products and systems. it is hoped that many of them will be interested in responding to this opportunity. the program will include: "a systems approach to selection of alternatives" -resource sharing-camponents-communications options-planning strategy. joseph a. rosenthal university of california, berkeley.

an in-process file of individual items being purchased by stanford; an on-line catalog (the catalog data file) of all items cataloged through the system, whether copy was derived from library of congress marc data, was input from non-marc cataloging copy, or resulted from stanford's own original cataloging efforts; and a file of see, see also, and explanatory references (the reference file) to the catalog data file. in addition, during september and october 1974, the 85,000 bibliographic and holdings records (already in machinereadable form on magnetic tape) representing the entire j. henry meyer memorial undergraduate library was convmted to on-line meyer catalog data and meyer reference files in ballots. these files are publicly available through spires (stanford public information retrieval system) to any person with a terminal that can dial up the stanford center for information processing's academic computer services computer (an ibm 360 model 67) and who has a valid computer account. the marc file can be searched through the following index points: lc card number personal name corporate/ conference n arne title the in-process, catalog data, and reference files for stanford and for meyer can also be searched as spires public subfiles through the following index points: ballots unique record identification number personal name corporate/ conference name title subject heading (catalog data and reference file records only) call number (catalog data and reference file records only) lc card number the title and corporate/ conference name indexes are word indexes; this means that each word is indexed individually. search requests may draw on more than one index at a time by using the logical operators "and," "or," and "and not" to combine index values sought. if you plan to use spires to search these files, or if you would like more information, a publication called gttide to ballots files may be ordered by writing to: editor, library computing services, s.c.i.p.-willow, stanford university, stanford, ca 94305. this document contains complete information about the ballots files and data elements, how to open an account number, and how to use spires to search ballots files. a list of ballots publications and prices is also available on request. as additional libraries create on-line files using ballots in a network environment, these files will also be available. these additions will be announced in ]ola technical commttnications. data base news interchange of alp and ei data bases a national science foundation grant (gn-42062) for $128,700 has been awarded to the american institute of physics (aip), in cooperation with engineering index ( ei), for a project entitled "interchange of data bases." the grant became effective on may 1, 1974, for a period of fifteen months. the project is intended to develop methods by which ei and alp can reduce their input costs by eliminating duplication of intellectual effort and processing. through sharing of the resources of the two organizations and an interchange of their respective data bases, alp and ei expect to improve the utilization of these computer-readable data bases. the basic requirement for the developtechnical communications 317 ment of the interchange capability for computer-readable data bases is the establishment of a compatible set of data elements. each organization has unique data elements in its data base. it will therefore be necessary to determine which of the data elements are absolutely essential to each organization's services which elements can be modified, and wh~t other elements must be added. mter the list of data elements has been established, it will be possible to unite the specifications and programs for format conversions from alp to ei tape format and vice versa. simultaneously, there will be the development of language conversion facilities between ei' s indexing vocabulary and alp's physics and astronomy classification scheme (pacs). it is also planned to investigate the possibility of establishing a computer program which can convert alp's indexing to ei's terms and vice versa. with the accomplishment of the above tasks, it will be possible to create new services and repackage existing services to satisfy the information demands in areas of mutual interest to engineers and physicists, such as acoustics and optics. eric data base users conference the educational resource information center (eric) held an eric data base users conference in conjunction with the 37th annual meeting of the american society for information science (asis) in atlanta, georgia, october 13-17, 1974. the eric data base users conference provided a forum for present and potential eric users to discuss common problems and concerns as well as interact with other components of the eric network: central eric, the eric processing and reference facility, eric clearinghouse personnel, and information dissemination centers. although attendees have in the past been primarily oriented toward machine use of the eric files, all patterns of usage were represented at this conference, from manual users of printed indexes to operators of national on-line reh·ieval systems. 318 ]oumal of library automation vol. 7/4 december 1974 a number of invited papers were presented dealing with subjects such as: • the current state and future directions of educational information dissemination. sam rosenfeld (nie), lee burchina! (nsf). • what services, systems, and data bases are available? marvin gechman (information general), harvey marron (nie). • the roles of libraries and industry, respectively, in disseminating educational information. richard de gennaro (university of pennsylvania), paul zurkowski (information industry association) . several organizations (national library of canada, university of georgia, wisconsin state department of education) were invited to participate in "show and tell" sessions to describe in detail how they are using the eric system and data base. a status report covering eric on-line services for educators was presented by dr. carlos cuadra (system development corporation) and dr. roger summit (lockheed). interactive discussion groups covered a number of subjects including: • computer techniques-programming methods, use of utilities, file maintenance, search system selection, installation, and operation. • serv:uig the end user of educational information. • introduction to the eric systemwhat tools, systems, and services are available and how are they used? • beginning and advanced sessions on computer searching the eric files. online terminals were used to demonstrate and explain use of machine capabilities. commercial services and developments scope data inc. ala train compatible terminal printers scope data inc. currently is offering a high-speed, nonimpact terminal printer for use in various interactive printing applications. capability can be included in the series 200 printer as an extra-cost feature to print the eight-bit ascii character set for ala character set with 176 characters. for further information contact alan g. smith, director of marketing, scope data inc., 3728 silver star rd., orlando, fl 32808. institute for scientific information puts life sciences data base on-line through system development corporation the institute for scientific information (lsi) has announced that it will collaborate with system development corporation (sdc) to provide on-line, interactive, computer searches of the life sciences journal literature. scheduled to be fully operational by july 1, 1974, the isi-sdc service is called scisearch® and is designed to give quick, easy, and economical access to a large life sciences literature .file. stressing ease of access, the sdc retrieval program, orbit, permits subscribers to conduct extremely rapid literature searches through two-way communications terminals located in their own facilities. mter examining the preliminary results of their inquiries, searchers are able to further refine their questions to make them broader or narrower. this dialog between the searcher and the computer (located in sdc's headquarters in santa monica, california) is conducted with simple english-language statements. because this system is tied in to a nationwide communications network, most subscribers will be able to link their terminals to the computer through the equivalent of a local phone call. covering every editorial item from about 1,100 of the world's most important life sciences journals, the service will initially offer a searchable ille of over 400,000 items published between april 1972 and the present. each month approximately 16,000 new items will be added until the average size of the file totals about one-half million items and represents two-and-one-half years ·of coverage. to assure subscribers maximum retrieval effectiveness when dealing with this massive amount of information, the data base can be searched in several ways. included are searches by keywords, word stems, word phrases, authors, and organizations. one of the search techniques utilized-citation searching-is an exclusive feature of the lsi data base. for every item retrieved through a search, subscribers can receive a complete bibliographic description that includes all authors, journal citation, full title, a language indicator, a code for the type of item (article, note, review, etc.), an lsi accession number, and all the cited references contained in the retrieved article. the accession number is used to order full-text copies of relevant items through lsi's original article tear sheet service (oats®). this ability to provide copies of every item in the data base distinguishes the lsi service from many others. current library of congress catalog on-line for reference searches information dynamics corporation (idc) has agreed to collaborate with system development corporation (sdc) to provide reference librarians, researchers, and scholars with on-line interactive computer searches of all library materials being cataloged by the library of congress. scheduled to be fully operational as of october 1, 1974, the sdc-idc service is called sdc-idc/libcon and is designed to give quick, easy, and economical access to a large portion of the world's scholarly library materials. as in the lsi service described above, the data base can be searched in several ways. included are compound logic searches by keywords, word stems, word phrases, authors, organizations, and subject headings for most english materials. one of the search techniques utilized-string searching-is an exclusive feature of sdc's orbit system. keyword searching of cataloged items including all foreign materials processed by the library of congress technical communications 319 is an exclusive feature of the idc data base not currently available in other online marc files. for individual items retrieved through a search, subscribers can receive a bibliographic description that includes authors, full title, an idc accession number, the lc classification number, and publisher information. standards the isad committee on technical standards for library automation invites your participation in the standards game editor's note: the tesla reactor ballot will be provided in f01'thcoming issues. to use, photocopy the ballot fol'm, fill out, and

this procedure is geared to handle both reactive (originating from the outside) and initiative (originating from within ala) standards proposals to provide recommendations to ala's representatives to existing, recognized standards organizations. to enter the procedure for an initiative standards proposal you must complete an "initiative standards proposal" using the outline which follows: initiative standard proposal outlinethe following outline is designed to facilitate review by both the committee and the membership of initiative standards proposals and to expedite the handling of the initiative standard proposal through the procedure. since the outline will be used for the review process, it is to be followed explicitly. where an initiative standard requirement does not require the use of a specific outline entry, the entry heading is to be used followed by the words "not applicable" (e.g., where no standards exist which relate to the proposal, this is indi320

(optional) specify the standard proposal using record layouts, mechanical drawings, and such related documentation aids as required in addition to text exposition where applicable (specifications of the standard). kindly note that the outline is designed to enable standards proposals to be written following a generalized format which will facilitate their review. in addition, the outline permits the presentation of background and descriptive information which, while important during any evaluation, is a prerequisite to the development of a standard. tesla reactor ballot identification number for standing requirement reactor information name-----'----------tiue ______________________ ___ organization --------------addrms _____________ ___ city ___ _ state ___ zip __ _ telephonea 1:-:::-rea::+----~---­ need (for this standard) for d against 0 specification (a presented in this requirement) for 0 against 0 ext. can you participate in the development of this. standard -.,.---------==----0 no d yes reason for position: (use format of proposal. · additional pages can be used if required) the reactor ballot is to be used by members to voice their recommendations relative to initiative standards proposals. the reactor ballot permits both "for" and "against" votes to be explained, permitting the capture of additional information which is necessary to document and communicate formal standards proposals to standards organizations outside of the american library association. as you, the members, use the outline to present your standards proposals, tesla will publish them in jola-tc and solicit membership reaction via the reactor ballot. throughout the process tesla will insure that standards proposals are drawn to the attention of the applicable american library association division or committee. thus, internal review usually will proceed concurrently with membership review. from the review and the reactor ballot tesla will prepare a "majority recommendation" and a "minority report" on each standards proposal. the majority recommendation and minority report so developed will then be transmitted to the originator, and to the official american library association representative on the appropriate standards organization where it should prove a source of guidance as official votes are cast. in addition, the status of each standards proposal will be reported by tesla in jola-tc via the standards scoreboard. the committee (tesla) itself will be nonpartisan with regard to the proposals handled by it. however, the committee does reserve the right to reject proposals which after review are not found to relate to library automation. input to the editor: we have been asked by the members of the ala interdivisional committee on representation in machine readable form of bibliographic information, (marbi) to respond to your editorial in the june 1974 issue of the journal of library automation. this editorial dealt with the council of library resources' [sic] involvement in a wide range of projects, ranging from the sponsorship of a group which is attempting to develop a subset of marc for use in inter-library exchange technical communications 321 of bibliographic data ( cembi), to management of a project which has as its goal the creation of a national serials data base, (conser), and, more recently, to the convening of a conference of library and a&i organizations to discuss the outlook for comprehensive national bibliographic control. you raised several legitimate questions: 1) has sufficient publicity been given to these activities of the council so that all, not just a few, libraries are aware of what is happening and have an opportunity to exert an influence on developments? and, 2) is the council bypassing existing channels of operation and communication? you also suggest that proposals from groups such as cembi be channeled through an official ala committee such as marbi for intensive review and evaluation. it should be pointed out that marbi is not charged with the development of standards. it acts to monitor and review proposals affecting the format and content of machine readable bibliographic data, where that data has implications for national or international use. this applies to proposals emanating from cembi and conser as well as from other concerned groups. all indications to date are that the council is fully aware of marbi's role and will not bypass marbi. a number of members of marbi are also members of cembi and marbi is represented on the conser project. also reassuring is the fact that, unless we allow lc to fall by the wayside in its role as the primary creator and distributor of machine readable data, any standards for format or content developed by a council-sponsored group will eventually be reflected in the marc records distributed by lc. the library of congress has issued a statement, published in the june 1974 issue of jola, to the effect that it will not implement any changes in the marc distribution system which are not acceptable to marbi. marbi and lc have worked out a procedure whereby all proposed changes to marc are submitted to marbi. they are then published in ]ola and distributed to mem322 journal of library automation vol. 7/4 december 1974 hers of the marc users discussion group for comments. comments are collected and evaluated by marbi and a report submitted to lc, with its recommendations. the marbi review process does not guarantee perfection and there is no assurance that everyone will be satisfied. compromise and expediency are the name of the game in this extremely complicated and uncharted area of standards for machine readable bibliographic data. however the council has undoubtedly learned from the isbd(m) experience that it cannot make decisions which affect libraries without the greatest possible involvement of librarians. it is the feeling of the marbi committee members that the council intends to work with marbi in future projects which fall into marbi's area of concern. velma veneziano marbi past chairperson ruth tighe chairperson editor's note: it is gratifying to note that marbts response reflects the opinions expressed in the june 1974 editorial. the library community will doubtless. be pleased to learn of clr's intention to work closely with marbi.-skm to the editor: as briefly discussed with you, yom editorial in the june 1974 issue of jola is both admirable and disturbing (to me, at least). the problem of national leadership in the area of library automation is a critical problem indeed. being in the ''boondocks" and far removed from the scene of action, i can only express to you my perception as events and activities filter through to me. i can remember as far back as 1957 when adi had a series of meetings in washington, d.c. trying to establish a national program for bibliographic automation. i have been through eighteen years of meetings, committees, conferences, etc. concerned with trying to develop a national plan for bibliographic automation and information storage and retrieval systems. i have worked with nsf, usoe, department of commerce, u.s. patent office, engineering and technical societies, dod agency-the entire spectrum. i spent a good many years working in adi and asis, sla, andmost recently ala. at no time were we able to make significant progress towards a national system. even the great airlie house conference did not produce any significant changes in the fragmented, competitive "non-system." it has only been in the recent past since clr has taken an aggressive posture that i am able to see the beginning of orderly development of a national automated bibliographic system. i certainly agree that any topic as critical as those being discussed by cembi should be in the public domain, but i also believe that the progress made by cembi would not have been possible without clr taking the initiative in getting these key agencies together. thank goodness someone quit talking and started doing something at the national level! i sincerely believe that in the absence of a national library and with the cmrent lack of legally derived authority in this arena, clr provides a genuine service to the total library community in establishing cembi. hopefully, your very excellent article (in the same issue of jola) on "standards for library automation ... " will help to put the entire issue of bibliographic record standards into perspective. as a former chemist and corrosion engineer, i am fully aware of the absolute necessity for technical standards. i am also fully aware of the necessity of developing technical standards through the process you outlined in your article. hopefully, clr action with cembi will expedite this laborious process and help to push our profession forward into the twentieth century. since we ourselves have not been able to do it through all these years, i am personally grateful that some group such as clr took the initiative and forced us to do what we should have done years ago. maryann duggan slice office di1·ector editor's note: positive action and progmssive movement are, of course, desirable and are often lacking in large organizations. however, posit·ive action without communication of this action to the affected population can only be detrimental. on issues of the complexity of those addressed by cembi and conser, review by the library community is always useful, even though action may be temporarily delayed.-skm to the editor: on page 233 of the september issue of lola there is a report from the information industry association's micropublishing committee chairman (henry powell). he states that", .. the committee spelled out several areas of concern to micropublishers which will be the subject of committee action .... " one of the concerns of the committee is that a z39 standards committee has recommended "standards covering what micropublishers can say about their products." (emphasis mine.) technical communications 323 as chairman of the z39 standards subcommittee which is developing the advertising standard referred to, i wish to point out that there is no intention on the part of the subcommittee to tell micropublishers what they can say nor what they may say about their products. the subcommittee, which is composed of representatives from three micropublishing concerns, two librarians, and myself, has from the beginning taken the view that the purpose of the standard would be to provide guidance for micropublishers and librarians alike. we are most anxious that no one feel that the subcommittee has any intention of attempting to use the standards mechanism to tell any micropublisher how he must design his advertisements. in addition it should be noted that no ansi standard is compulsory. carl m. spaulding program officer council on library resou1·ces editorial board thoughts: library analytics and patron privacy ken varnum information technology and libraries | december 2015 2 two significant trends are sweeping across the library landscape: assessment (and the corresponding collection and analysis of data) and privacy (of records of user interactions with our services). libraries, perhaps more than any other public service organization, are strongly motivated to assess their offerings with dual aims. the first might be thought of as an altruistic goal: understanding the needs of their particular clientele and improving library services to meet those needs. the second is perhaps more existential: helping justify the value libraries create to whatever sources of funding are necessary to impress. both are valid and important. it is hard to argue that improving services, focusing on actual needs, and maintaining funding are in any way improper goals. however, this desire is often seen as being in conflict with exploring too deeply the actions or needs of individual constituents, despite librarians’ historical and deeply-held belief that each constituent’s precise information needs should be explored and provided for through personalized, tailored services. solid assessment cannot happen without solid data. libraries have historically relied on qualitative surveys of their users, asking users to evaluate the quality of the services they receive. being able to know more details and ask directed questions of individuals who used services is possible in the traditional library setting through invitations to complete surveys after individual interactions such as a reference or circulation desk interaction, library program, visit to a physical location, or even a community-wide survey invitation. focus groups can be assembled as well, of course, once a library has identified a real-world group to study. however, those samples are more often convenience samples or—unless a library is able to successfully contact and receive responses from across the entire community— somewhat self-selected. assessment that leads to new or improved services relies much more heavily on broad-based understanding of the users of a system. libraries have been able to do limited quantitative studies of library usage—at its simplest, counting how many of this were checked out, how many of that was accessed, and how many users were involved. these metrics are useful, but also limited, particularly at the scale of a single library. knowing that a pool of resources is heavily used is helpful; even knowing that a suite of resources is frequently used collectively is beneficial. however, tying use of resources to specific information needs or information seekers, whether this is defined as ken varnum (varnum@umich.edu), a member of the ital editorial board, is senior program manager for discovery, delivery, and learning analytics at the university of michigan library, ann arbor, michigan. mailto:varnum@umich.edu editorial board thoughts: library analytics and patron privacy | varnum doi: 10.6017/ital.v34i4.9151 3 individuals or ad hoc collections of users based on situational factors such as academic level, course enrollments, etc. these more specific grouping rely on granular data that for many libraries—especially academic ones—are increasingly electronic. we are at a point in time when we have the potential to leverage wide swathes of user data. and this is where the second trend, privacy, comes to bear. protecting user privacy has been a guiding principle of librarianship in the united states (in particular) since the 1970s, as a strong reaction to u.s. government (through the fbi) requests to provide access to circulation logs for individuals under suspicion of espionage. this was in the early days of library automation, when large libraries with automated ils systems could prevent future disclosure through the straightforward strategy of purging transaction records as soon as the item was returned. this practice became standard operating procedure in libraries, and expanded into new information service domains as they evolved over the following forty years. with good intentions, libraries have ensured that they maintain no long-term history for most online services. as a profession, we have begun to realize that the straightforward (and arguably simplistic) approaches we have relied on for so long may no longer be appropriate or helpful. over the past year, these conversations found focus through a project coordinated by the national information standards organization thanks to a grant from the andrew w. mellon foundation.1 the range of issues discussed here was far-reaching and touched on virtually every aspect of privacy and assessment imaginable. the resulting draft document, consensus framework to support patron privacy in digital library and information systems,2 outlines 12 principles that libraries (and the information service vendors they partner with) should follow as they establish “practices and procedures to protect the digital privacy of the library user.” this new consensus framework sets a series of guidelines for us to consider as we begin to move into this uncharted (for libraries) territory. if we are to record and make use of our users’ online (and offline, for that matter) footprints to improve services, improve the user experience, and justify our value, this document gives us an outline of the issues to consider. it is time (and probably long past time) that we make conscious decisions about how we assess our online resources, in particular, and do so with a deeper knowledge of both the resources used and the people using them. at the exact moment in our technological history when we find ourselves able to provide automated services at scale to our users through the internet and simultaneously record and analyze the intricate details of those transactions, we need to come to think clearly about what questions we have, what data we need to answer them, and be explicit about how those data points are treated. it is important that we start this process now and change our blunt practices into more strategic data collection and analysis. where 40 years ago we opted to information technology and libraries | december 2015 4 bluntly enforce user privacy by deleting the data, we should now take a more nuanced approach and store and analyze data in the service of improved services and tools for our user communities. we have the opportunity, through technology and a more nuanced understanding of privacy, to conduct a protracted reference interview with our virtual users over multiple interactions… and thereby improve our services. references 1. http://www.niso.org/topics/tl/patron_privacy/ 2.

state university, detroit, michigan. 263 library literature generally assumes that com is bette1· suited to staff rather than patron use applications. this paper describes a com serials holdings list intended for patton use. the application and conversion from paper to com are described. emphasis is placed on the selection of an appropriate microformat and easily operable viewing equipment as conditions of success fo1' patron use. as a marriage of dynamic information-handli11g technologies, computer output microfilm (com) is a systems tool of· potentially great significance to librarians. several libraries have reported successful com applications initiated within the last few years. the two most recent-fischer's description of four com-generated reports used by the los angeles public libraries and bolefs account of a com book catalog at the washington university school of medicine library-stress the time, space, and cost savings so frequently reported in analyses of the advantages of com.1• 2 this article describes the substitution of microfilm for paper as the computer output medium in one of the most common library automation applications, a serials holdings list intended for use by library patrons. it is interesting that, at a time when librarians are insisting on the importance of patron acceptance of technological innovation, the recent literature reports com applications intended solely for staff use. bole£, in fact, lists staff rather than patron use among the characteristics of potentially successful library com applications. the report that follows suggests, however, that careful attention to the selection of an appropriate microformat and viewing equipment can successfully extend the effectiveness of com to include pab:on-use library automation applications. the application the union list of se1·ials in the wayne state university libraries is a computer-generated alphabetical listing, by title, of serials held by the wayne state university library system and some biomedical libraries in the detroit metropolitan area. sullivan describes it as "informative in purpose and conventional in method."3 as with many similar applications, serials i' 264 journal of library automation vol. 7 j 4 december 197 4 holdings were automated in order to unify and disseminate hitherto separate, local records. the list is primarily a location device, giving for each title the location within the library system and information on the holdings at each location. it is updated monthly, the july 1974 issue totalling 1,431 pages. in paper form, twenty copies produced on an ibm 1403 line printer using four-ply carbon-interleaved forms were distributed for use throughout the library system. the list shares some of the characteristics that have marked other successful com applications. 4 it consists of many pages and has a sizeable distribution. quick retrieval of information is essential. use is for reference rather than reading. there is no need to annotate the list and no need for paper copies, although the latter requirement would not rule out the use of com for this particular application. patrons simply consult the list to determine whether the library's holdings include a particular serial and then proceed to the indicated location. it is interesting that serials holdings lists, long recognized as an excellent introductory library automation application, should also prove an excellent first application for com. complexities of format and viewing equipment selection aside, the conversion of output from paper to microfilm presented no problems. since the wayne state university computing and data processing center does not have com capability, the university libraries, after careful consideration of several vendors, contracted with the mark larwood company, a microfilm service bureau equipped with a gould beta com 700l recorder. the beta com is a crt-type com recorder with an uppercase and lowercase character set, forms-overlay capability, proportional spacing, underlining, superscripts, subscripts, italics, and a universal camera capable of producing 16, 35, 70, and 105mm microformats at several reduction ratios. a decisive factor in the selection of this particular vendor was the beta com's dedicated pdp-8/l minicomputer that enables the com recorder to accept an ibm 1403 print tape, thereby greatly simplifying conversion and eliminating the expense of reprogramming. microformat selection as ballou notes, discussions of com have tended to concentrate more on the computer than on micrographics, but for a patron-use com application the selection of an appropriate microformat is of the greatest importance.5 however, there has been an unfortunate emphasis placed, both in the literature of micrographics and by vendors, on microfiche, the format now dominating the industry, especially in com applications. such emphasis ignores the fundamental rule of systems design, that form follows function. each of the microformats has strengths and weaknesses that must be analyzed with reference to the application at hand. for a patron-use, com-generated serials holdings list, ease of use with a minimum of patron film handling is a paramount consideration. microfiche is clearly unsuitable for a list of over 1,400 pages. even at 42x reduction, the paserials list/saffady 265 tron would be forced to choose from among seven :fiches, each containing 208 pages. the difficulties of handling and loading, combined with library staff involvement in a program of user instruction, make fiche an unattractive choice. instead, the relatively large size of the holdings list suggests that one of the 16mm roll formats offers the best prospects of containing present size and future growth within a single microform. the disadvantages of the conventional 16mm open spool-the necessity of threading film onto a take-up reel before viewing-can be minimized by using a magazine-type film housing. the popular cartridge format eliminates much film handling, but cartridge readers are very expensive, necessitating a considerable investment where many readers are required. even with the cartridge, it is still possible for a patron to unwind the film from the take-up reel, necessitating rethreading before viewing. fortunately, microfilm cassettes overcome this difficulty. unlike the cartridge format, 16mm cassettes feature selfcontained supply and take-up reels. the film cannot be completely unwound from the take-up reel and the cassette can be removed from the viewer at any time without rewinding. patron film handling is virtually eliminated. the cassette format has proven very popular with british libraries, where it has been used with satisfactory results in com applications.6 viewing equipment success in format choice is contingent on the selection of appropriate viewing equipment. as larkworthy and brown point out, the best viewer for patron-use com applications is one that can easily be operated by the least mechanically inclined person.7 fortunately, cassette viewers, while limited in number, tend to be very easy to operate. the viewer chosen for use with the union list of serials, the memorex 1644 autoviewer, features a simple control panel, fixed 24x reduction, easily operated focus and scan knobs, motorized film drive for high-speed searching, and a manual hand control for more precise image positioning. the screen measures eleven by fourteen inches in size, with sufficient brightness for comfortable ambient light viewing. other cassette viewers examined, however satisfactory they might be in other respects, failed to meet the peculiar requirements of this particular application. discussion since its introduction in april 1974, the com-generated union list of serials in the wayne state university libraries has enjoyed a satisfactory reception. patrons have learned to consult the com list with little difficulty. the selection of an appropriate microformat and easily operated viewing equipment have kept staff involvement in patron instruction to a minimum. there appears to be no reason for limiting potential library com applications to those used primarily or solely by staff members. given the 266 journal of library automation vol. 7/4 december 1974 severity of the current paper shortage, the consequent rise in paper prices, and serious questions about the availability of paper at any price, com merits serious consideration as an alternative output medium for the widest range of library automation applications.

rooted in research and development efforts from the late 1990s and early 2000s when the cultural heritage sector started to tackle these challenges in isolation. since then, the commercial sector has sought to solve similar challenges, using different technical strategies such as software defined storage and function-as-a-service. while commercial sector solutions are not necessarily created with long-term preservation in mind, they are well aligned with the digital preservation use case. the cultural heritage sector can benefit from adapting these modern approaches to increase sustainability and leverage technological advancements widely in use across fortune 500 companies. introduction most digital preservation systems and practices are rooted in research and development efforts from the late 1990s and early 2000s when the cultural heritage sector started to tackle these challenges in isolation. since then, the commercial sector has sought to solve similar challenges, using different technical strategies. while commercial sector solutions are not necessarily created with long-term preservation in mind, they are well aligned with the digital preservation use case because of similar features. the cultural heritage sector can benefit from adapting these modern approaches to increase sustainability and leverage technological advancements widely in use across fortune 500 companies. in order to understand the benefits, this article will examine the principles of sustainability and how they apply to digital preservation. typical preservation activities that use technology will be described, followed by how these activities occur in a 20th-century technical infrastructure model. after a discussion on advancements in the it industry since the conceptualization of the 20thcentury model, a theoretical 21st-century model is presented that attempts to show how the cultural heritage sector can employ industry advancements and the beneficial impact on sustainability. galleries, libraries, archives, and museums cannot afford to ignore the sustainability of managing and preserving digital content and neither can distributed digital preservation or commercial service providers.1 budgets lag behind economic inflation while the cost of and amount of materials to purchase rises, coupled with the need to hire more employees to do this work. if digital preservation programs are going to scale up to enterprise levels and operate in perpetuity, it is imperative to update technical approaches, adopt industry advancements, and embrace cloud technology. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 2 sustainability for digital preservation programs to succeed, they must be sustainable per the triple bottom line or they risk subverting their mission. the triple bottom line definition of sustainability identifies three pillars: people (labor), planet (environmental), and profit (economic).2 while there are typically few people with digital preservation in their job title within an organization, it’s a collaborative domain with roles and responsibilities distributed throughout organizations, reflecting the digital object lifecycle. it’s important that the underlying technical infrastructure can easily be supported and is not so complicated that it is hard to recruit systems administration staff. digital preservation consumes many technical resources and data centers have a substantial environmental impact. as ben goldman points out in “it’s not easy being green(e),” data centers consume an immense amount of power and require extravagant cooling systems that use precious fresh water resources.3 because there is no point in preserving digital content if there will be no future generation of users, responsible digital preservation programs will seek to reduce carbon outputs and the number of rare-earth elements in our technical infrastructure.4 while cultural heritage organizations rarely seek to make a profit, economic sustainability is vital to organizational health and costs for digital preservation must be controlled. modern technological infrastructures discussed here will help to increase sustainability by using widespread technologies and strategies for which support can be easily obtained, by reducing energy consumption, by minimizing reliance on hardware using rare-earth elements, and by leveraging advances in infrastructure components such as storage to perform digital preservation activities. basic digital preservation activities this paper will examine technical preservation activities and the author acknowledges that basic digital preservation activities are likely to include risk management and other non-technical concepts. while there is no formal, agreed-upon definition of what constitutes a set of basic digital preservation activities, bit-level digital preservation is a common baseline. bit-level digital preservation seeks to preserve the digital object as it was received, ensuring that you can get out an exact copy of what you put in, no matter how long ago the ingest occurred; however, with no guarantees as to the renderability of said digital object. two basic digital preservation activities are key to this strategy: fixity and replication. fixity fixity checking, or the “practice of algorithmically reviewing digital content to ensure that it has not changed over time,” is a foundational digital preservation strategy for verifying integrity that aligns with rosenthal et al.’s “audit” strategy.5 fixity is how preservationists demonstrate mathematically that the content has not changed since it was received. not all fixity is the same, however; fixity can be broken up into three types: transactional fixity, authentication fixity, and fixity-at-rest.6 transactional fixity transactional fixity is checked after some sort of digital preservation event7, such as ingest or replication. depending on the event, it’s desirable to use a non-cryptographic algorithm, such as crc32 or md5, when files move within a trusted system. when it’s only necessary to prove that a file hasn’t immediately changed, such as copying between filesystems, cryptographic algorithms are unnecessarily complex and are too expensive, in terms of compute consumption. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 3 authentication fixity authentication fixity proves that a file hasn’t changed over a long period of time, particularly since ingest. although one could use a chain of transactional fixity checks to cumulatively prove there has been no change, it’s often desirable to conduct one fixity check that can be independently verified. unbroken cryptographic algorithms, such as one from the sha-2 and sha-3 families, are well suited to this use case and worth the complexity and compute expense, particularly since this type of fixity check doesn’t have to be run as often. fixity-at-rest fixity-at-rest is when fixity is monitored while content is stored on disk. while some organizations may choose to only conduct fixity checks when files move or migrate, this strategy can miss bit loss due to media degradation, software or human error, or malfeasance that is only discovered when the file is retrieved.8 a common approach for monitoring fixity-at-rest is to systematically conduct fixity checks on all or a sample of files at regular intervals. these types of fixity checks may or may not use cryptographic algorithms, depending on their availability.9 replication replication is another cornerstone of achieving bit-level digital preservation. the national digital stewardship alliance’s 2019 levels of digital preservation, a popular community standard, recommends maintaining at least two copies in separate locations, while noting three copies in geographic locations with different disaster threats is stronger.10 all of these copies must be compared to ensure fixity is maintained. an important concept to consider when thinking about replication is the independence of each copy. according to schaefer et al.’s user guide for the preservation storage criteria, “the copies should exist independently of one another in order to mitigate the risk of having one event or incident which can destroy enough copies to cause loss of data.”11 in other words, a replica should not depend on another replica, but instead depend on the original file. advanced digital preservation activities when considering more robust digital preservation strategies beyond bit-level preservation, additional activities must be considered to ensure that the information contained within digital files can be understood. implementation of these activities may vary by digital object, depending on the digital preservation goal and appraised value of the content. this paper only describes a handful of the many advanced digital preservation activities as illustrative examples; the ideas in this paper could be applied to most advanced activities. metadata extraction digital files often contain various types of embedded metadata that can be used to help describe both its intellectual content and technical characteristics. this metadata can be extracted and used to populate basic descriptive metadata fields, such as title or author. extracted technical metadata is useful for broader preservation planning, but also for validating technical characteristics in derivative files. for example, if generating an access file for digitized motion picture film, it’s necessary to know the color encoding, aspect ratio, and frame rate. if these details are ignored, the access derivative may appear significantly different than the original file and give a false impression to users. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 4 file format conversions file format conversions help to ensure the renderability of digital content. there are two types of file format conversions to consider: normalization and migration. normalization generally refers to proactively converting file formats upon ingest to retain informational content, e.g., converting a wordperfect document to plain text or pdf when only the informational content is desired. migration may occur at any time: upon ingest, upon access, or any time while an object is in storage. migration occurs when file formats are converted to a newer version of the same format, e.g., microsoft access 2003 (mdb) to microsoft access 2016 (accdb) or to a more stable and open format that retains features, e.g., microsoft access 2016 (accdb) to sqlite. versioning versioning, or the retention of past states of a digital object with the ability to restore previous states, is complex to implement and not always necessary. an organization might choose to apply versioning to subsets of digital content, such as within an institutional repository, but not for born-analog, or digitized material. additionally, an organization may choose to version metadata only, ignoring changes to the bitstream, such as for born-analog digital objects. figure 1. the infrastructure architecture for a typical 20th-century stack. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 5 the 20th century technical infrastructure the technical infrastructure that enables digital preservation can come in many forms. while technology has advanced over the past thirty years, the cultural heritage sector, particularly where digital preservation is concerned, has been slow to adapt. below are descriptions of three common components of a typical server stack (technical infrastructure), though the author acknowledges that some organizations have already moved past this model. figure 1 is a diagram of the typical 20th-century stack. storage storage, at the core of digital preservation, has benefitted from rapid technological advancement since computers first started storing information on punch cards and magnetic media. twentiethcentury servers often use three main types of storage: file, block, and object. file storage file storage is what most people are familiar with. a filesystem interfaces with the underlying storage technology (block or object) and physical media (hard disk drives, solid state drives, tapebased media, or optical media) to present users with a hierarchy of directories and subdirectories to store data. this data can easily be accessed by users or applications using file paths, while the filesystem negotiates the actual bit-locations on the physical media. the choice of filesystem can impact data integrity (fixity), although choice may be limited by operating system. in the 20th century, journaling filesystems offered the most data protection as the filesystem keeps track of all changes; in the event of a disk failure, it’s possible to recover more data if a journaling filesystem is used. block storage block storage uses blocks of memory on physical media (disk, tape, etc.) that are managed through a filesystem to present volumes of storage to the server. all interactions between server and storage are handled by the filesystem via file paths, though the data is stored on scattered blocks on the media. block storage directly attached to a server is often the most performant option, the data does not travel outside the server. network attached storage, in which an external file system is mounted to the server as if it were locally attached block storage, requires data to travel through cables and networks before it gets to the server, which decreases performance. object storage object storage, which still uses tape and disk media, is an abstraction on top of a filesystem. instead of using a filesystem to interact directly with storage media, the storage media is managed by software. the software pools storage media and interactions happen through an api, with files being organized into “buckets” instead of using a filesystem with paths. object storage is webnative and the basis for commercial cloud storage. software-defined storage, which is discussed in more detail later in this article, also allows users to create block storage volumes that can be directly mounted to virtual servers as part of a filesystem or to create network shares that present the underlying storage to users via a filesystem.12 both block and object storage can be used for high-performance storage, hot storage (online), cold storage (nearline), and offline storage. generally, tape and slower performing hard disks are used for offline and nearline storage; faster performing hard disks are used for online storage. solidinformation technology and libraries december 2021 a 21st century technical infrastructure | tallman 6 state drives (ssds) using non-volatile memory express (nvme) protocols are best suited for highperformance storage.13 in the 2019 storage infrastructure survey, by the national digital stewardship alliance, 60% of those aware of their organizational infrastructure reported a reliance on hardware-based filesystems (file and block storage) while about 15% used software-based filesystems (object storage), with 14% reporting a hybrid approach.14 this indicates that the cultural heritage sector continues to rely more on file and block storage and is not yet fully embracing object storage. the survey did not probe into why this might be. servers: physical and virtual twentieth-century technical infrastructures relied primarily upon physical servers. physical servers, also called bare metal, dominated the server landscape up through roughly 2005. virtual servers arrived on the scene after “vmware introduced a new kind of virtualization technology which … [ran] on the x86 system” in 1999.15 server virtualization facilitated a fresh wave of innovation by making it easier and more inexpensive to create, manage, and destroy servers as necessary. dedicating physical servers to one or a limited number of applications requires more resources and expends a higher carbon cost; virtual servers can be highly configured for their precise needs and this configuration can be changed using software, rather than changing parts on a physical server, resulting in less waste. cultural heritage organizations have been slow to fully adapt virtual servers. the 2019 ndsa storage infrastructure survey reports that 81% of respondents continue to rely on physical servers with 63% of respondents using virtual servers. fewer than 10% reported using containers, an even more efficient virtualization technology.16 containers are an evolution of virtual servers that act like highly optimized, self-contained servers doing a specific activity.17 applications and microservices in the 20th century, applications often required dedicated servers. business logic was handled by applications or microservices that ran on top of the server and storage, the highest level in the stack. there are advantages to handling the business logic at this high level: it’s completely in the control of the developer and can be finely tuned to the needs. unfortunately, this is also an expensive place to handle all business logic as the application needs to be maintained over time and there’s overhead involved in working at this level of the stack. microservices, in this server model, are generally specific commands that can be invoked as needed. while called microservices because they can be applied individually, they still run in this expensive part of the stack and have the same downsides as applications. in digital preservation systems using this type of architecture, basic and advanced digital preservation activities occur within this application layer. fixity can be a costly activity. garnett, winter, and simpson, in their paper “checksums on modern filesystems, or: on the virtuous consumption of cpu cycles,” point out that “calculating full checksums in software is not efficient” and “increases wear and tear on the disks themselves, actually accelerating degradation.”18 fixity, when done this way, is a linear process that requires every file to be read from disk so a checksum can be calculated; when performing fixity over large amounts of content, this is very inefficient and time consuming. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 7 preservation activities in the 20th-century stack in this model of infrastructure, many cultural heritage institutions are relying on practices created when the field of digital preservation was emerging. basic activities basic preservation activities take a generalized approach and mostly occur in the costly application and microservices layer. this follows the general approach of application development from the commercial sector in the 20th century. fixity although there are differences in frequency, most organizations do not currently make distinctions between transactional fixity, authentication fixity, or fixity-at-rest. common current practices use the same method (md5, sha-256, sha-512) for all fixity checks.19 this inefficient approach take place in the application and microservices layer and uses more compute power than necessary, increasing the environmental impact. replication in most 20th-century stacks, replications are handled in the application layer, where it is most costly in terms of computational power and labor to maintain, having a negative impact on sustainability. some are using 20th-century microservices are well. advanced digital preservation activities like basic preservation activities, advanced ones chiefly take place in the application and microservices layer if they occur at all. metadata extraction and file format conversion metadata extraction and file format conversion tends to occur only upon ingest as a one-time event. archivematica, the popular open-source digital preservation system, uses 20th-century microservices for each and they only occur during the transfer (ingest) process.20 other systems often include this in the business logic of the application layer. versioning version control is a feature that many organizations choose not to implement. the 2019 ndsa storage infrastructure surveys shows that fewer than half (40) of respondents (83) used any type of version control.21 version control is hard to implement in a custom system, with alternative approaches. fedora, a digital preservation backend repository, introduced support for versioning in the application layer around 2004.22 advances in the commercial sector since the conceptualization of the 20th-century stack, there have been significant advancements made in the general it industry. virtualization technology developed in the 1990s led to the proliferation of cloud computing and infrastructure that transformed the it industry in the early 2000s, leading to the “long-held dream of computing as a utility” or commodity.23 clouds can be public, where anyone is able to provision and use services, or private, where services are only available to a group of authorized users. public clouds are run in commercial data centers while private clouds are typically built-in privately-owned data centers, though it’s possible to use commercial data centers to build private clouds. hybrid clouds are also possible, typically combing private and public clouds, or combining on-premises infrastructure with a private or public cloud. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 8 in 2009, researchers at uc berkley identified three strong reasons why cloud computing has been so widely adopted: the illusion of vertical scaling on demand, elimination of upfront cost, and the ability to pay for short-term resources.24 surveys from the ndsa and the beyond the repository grant project show a steady, but slow adoption of cloud infrastructure by the cultural heritage community.25 it is unclear whether early adopters have chosen independently or simply followed it changes in their parent organizations. any organization can build a private cloud and take advantage of the benefits described in this article. using the cloud does not mean that you must contract with commercial cloud providers. some organizations may choose to build a private cloud if there are concerns over data sovereignty, mistrust in public clouds, or for other reasons. the ontario council of university libraries in canada has built a private cloud for its members called the ontario library research cloud using openstack, a suite of open-source software for building clouds.26 software-defined storage while virtualization enables cloud computing, software-defined storage is the foundation for cloud storage. software-defined storage combines inexpensive hardware with software abstractions to create a flexible, scalable, storage solution that provides data integrity.27 software-defined storage can use the same pool of disks to present all three of the common types of storage: file, object, and block. file storage is what most users are familiar with. software defined file storage creates a network file share from which files can be accessed on local devices via a filesystem.28 object storage in this environment is like a web-native file share; files are stored in buckets, which can be further organized by folders. files are not accessed through a filesystem, but are instead accessed through uris, which makes object storage very amenable to web applications and avoids some of the pitfalls of relying on filesystems. block storage is mostly used to mount storage to virtual servers, storage that is directly attached to the server as if it was a physical disk or volume mounted to the server. block storage is more performant than either file or object storage; as such it’s typically used for things like the operating system and application code, but not for storing content. all storage can be managed through apis, adding to its suitability for automation, software development, and it operations.29 hardware diversity software defined storage also has features that make a compelling use case for digital preservation. first, software defined storage accommodates hardware diversity. because software defined storage is an abstraction, it’s possible to combine different types of storage media, from different manufacturers and production batches to ensure some technical diversity and avoid risk from catastrophic failure from a hardware monoculture. fixity and integrity second, like the use of raid in traditional filesystems, file integrity can be strengthened through the use of erasure coding.30 erasure coding splits files into chunks and spreads them across multiple disks or potentially nodes such that the file can be reconstructed if some of the disks or nodes fail. this can be configured in different ways, depending on the amount of parity desired.31 replication third is replication of content. for cloud administrators, replication might be an alternative to erasure coding for ensuring data integrity; for digital preservationists, it’s a distinct strategy and information technology and libraries december 2021 a 21st century technical infrastructure | tallman 9 basic preservation activity. operating nodes in a software defined storage network can be in different availability zones; through object storage policies, content can be replicated as many times as necessary to provide mitigation of geographic based threats. it’s even possible to replicate to object storage in a different software defined storage network, helping to achieve organizational diversity as well. figure 2. the infrastructure architecture for a theoretical 21st-century stack. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 10 an updated technical infrastructure for the 21st century a theoretical 21st-century stack for digital preservation has many of the same components as its 20th-century antecedent. however, these components are used in different ways, largely due to technological advancements. leveraging these advancements to handle digital preservation activities at lower levels of the stack reduces the complexity of the business logic in the application layer. figure 2 shows an updated architecture diagram for this 21st-century stack, which may be used by an individual organization, consortium, or service provider planning to build a digital preservation system. the storage layer is built on software-defined storage with digital content primarily being stored as objects; these objects are stored using the oxford common file layout (discussed further later). physical bare metal servers are used to power virtual machines that host applications such as a digital repository. physical servers also host a container and function as a service to provide a suite of microservices for processing digital content. storage in this new stack, storage is primarily managed through software defined storage with data flowing over networks. there are currently two primary open-source options for running a software-defined storage service: gluster and ceph. both can be installed and run on-premises, in a private or public data center, or even contracted through infrastructure as a service (iaas). in his presentation at the 2018 designing storage architectures for digital collections meeting, hosted by the library of congress, glenn heinle recommended ceph over gluster where data integrity is the highest priority; however, others argue that gluster is better for long-term storage.32this is likely because ceph is better able to recover from hardware failures.33 file storage reliance on file storage has become minimal in this theoretical stack, with data primarily stored as objects. however, file storage may still be used; when it is, it benefits from using a modern filesystem. several modern filesystems have emerged since 2000, most notably zfs and openzfs34 with their innovative copy-on-write transactional model and methods for managing free space.35 both zfs and openzfs can also be configured to use raid-z, which maintains blocklevel fixity by calculating checksums for each block of data and verifying the checksum when accessed. this can be combined with simple software to touch every block on a regular basis to ensure fixity-at-rest. although this is a different approach than file-level fixity checks, it accomplishes the same thing in a much more efficient method: preservation metadata could be recorded for each block that contains part of the file.36 zfs has also inspired similar modern filesystems such as btrfs, apple file system (apfs), refs, and resier.37 however, even if this theoretical stack isn’t relying on file storage to persist data, software-defined storage is an abstraction that sits atop servers and disks (or tape) that do use filesystems.38 ironically, zfs is not the best option for the underlying disks as its data integrity features come with more overhead and data integrity can be achieved through different means with softwaredefined storage.39 block storage block storage comes in two forms in this future stack. many virtual servers will leverage the block storage offerings of the software defined storage service, attaching virtual disk blocks to virtual servers. however, the physical servers that support virtualization will still have some physically information technology and libraries december 2021 a 21st century technical infrastructure | tallman 11 attached storage using ssds (through nvme) to support high performance storage needs. this physically attached block storage is more performant than virtually attached block storage since the system has direct access to the disks and does not have to work through a virtually abstracted filesystem. object storage object storage has become the primary method of storing data in this theoretical stack. the flexibility of object storage, with its web-native apis and authentication, gives it an advantage as systems become less centralized and more integrations are needed. the natural scalability of object storage and the variety of private, public, and commercial offerings greatly simplifies geographic and organizational redundancy when replicating data. with software-defined storage, it’s also possible to offer hot (live) and cold (nearline, offline) options, giving flexibility for how data is stored to better optimize the storage for various needs. hot storage may use either hard disk or solid-state drives while cold storage would rely on tape or optical media. presently, options for running software defined storage on tape and optical media are mostly proprietary.40 while this would be a concern if these systems held the only copy, if the data is replicated to systems using other technology and media, this risk can be managed. while optical media has long been criticized for use as a preservation media, when well-managed, the risk may be overstated.41 oxford common file layout the oxford common file layout (ocfl) is a “shared approach to filesystem layouts for institutional and preservation repositories.”42 ocfl is a specification for organizing digital objects in a way that supports preservation while being computationally efficient. it has several advantages for use in digital preservation, such as the ability to rebuild a repository with only the files, it’s both human and machine readable, supports native error detection, allows objects to be efficiently versioned, and is designed to work with a variety of storage infrastructures.43 although some implementation details are still being worked out, ocfl can be used with object storage.44 ocfl is in production use and client libraries are available for javascript, java, ruby, and rust.45 in this future stack, all storage operations are handled by an ocfl client, which then interacts with the underlying software defined storage network as shown in figure 2. servers physical servers are used chiefly to support virtualization in this future stack. however, this stack moves beyond virtual servers and supports containers and serverless computing. virtual servers are chiefly used to support applications and databases while containers are perfectly suited for microservices running preservation activities. serverless, or function-as-a-service, is the next evolution in virtualization. while a container may be idling all the time, spinning into action when a microservice is called, serverless functions are run on-demand only. they can cost less when using commercial services as aws lambda or aws fargate where the customer is billed for usage only.46 though serverless functions can make use of containers, function-as-a-service platforms have emerged, such as apache openwhisk and openfaas that don’t always require containers. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 12 preservation activities in the 21st-century stack this 21st-century stack performs the same preservation activities as its predecessor. however, it generally does this at lower levels of the stack, in the infrastructure layers as opposed to the application and microservice layers. this change reduces the computational load on the stack and simplifies the business logic. basic activities fixity and replication are achieved leveraging a combination of microservices and softwaredefined storage. by optimizing the approach to fixity for each use case, instead of using the same computationally intensive method for all fixity, organizations can use less compute power. while fixity and replication still involve the microservice layer, it is a more targeted approach. transactional fixity transactional fixity is maintained through a function-as-a-service-based microservice. each time a file is moved, the microservice is triggered, which calculates a md5 checksum and compares it to a stored value that was created upon ingest. if there is a mismatch between the md5 values, a second microservice is called that fetches a valid file replica. while crc32 might be preferred (because it’s slightly less cpu-intensive), box has shown that crc32 values can differ depending on how they are calculated.47 a stored crc32 can only be reliably used to confirm fixity if the new calculation uses the exact same method because crc32 not a true specification—such as md5— and implementations may differ. crc32 is recommended only when it’s possible to calculate in the same manner, such as the same microservice. as this introduces technical complexity, some organizations may prefer to rely solely on md5 for transactional fixity. authentication fixity authentication fixity is maintained in much the same way as in the 20th-century model, except using a cryptographically secure checksum algorithm, such as sha-512 (part of the sha-2 family). however, distinguishing between transactional vs. authentication fixity allows more precise use of algorithms, only requiring more computationally intensive cryptography when it’s truly needed. authentication fixity may require the use of a container-based microservice, versus a function-asa-service, due to the increased computational need. fixity-at-rest fixity-at-rest, the most common type of fixity, is managed by the software-defined storage service and reported in preservation metadata. how this is achieved might look different, depending on which software-defined storage service is used. the ceph community has developed a new technology called bluestor which serves as a custom storage backend that directly interacts with disks, essentially replacing the need to use an underlying filesystem.48 bluestor calculates checksums for every file and verifies them when read. because this is all internal and managed by the same system, crc32 is the default algorithm, but multiple algorithms are supported. ceph will “scrub” data every week. scrubbing is the process of reading the file simply to verify the checksum, even if no user has accessed the file. because of the way ceph performs erasure coding, if a checksum is invalid, the file can be repaired. what remains to be done is writing a script that will read ceph’s internal metadata and record preservation events within the object’s preservation metadata for the fixity verification and any reparative actions. ryu and park propose a “markov failure and repair model” to optimize the frequency of data scrubbing and number of replicas such that the least amount of information technology and libraries december 2021 a 21st century technical infrastructure | tallman 13 power is consumed and that scrubbing occurs at off-peak times.49 it appears that this optimization causes less media degradation from the process of regularly reading the file, though empirical studies are needed to confirm that there is overall less degradation than conducting fixit checks through an application. gluster has a similar scrubbing process for fixity-at-rest in the optional bitrot feature, although it uses sha-256 by default, instead of crc32, which requires more computing power.50 replication replication in this future stack is mostly handled by the software-defined storage service, but microservices may play a role in achieving independence of copies.51 object storage policies allow the automatic copying of data into another region or availability zone that is within the software defined storage network. however, these copies are not replicas, or independent instances, because all copies are in a chain derived from the primary instance; if there is a problem anywhere in the chain, bad data will be copied. in addition to using object storage policies, microservices could be used to independently verify the fixity of downstream copies as well as trigger true replications to independent instantiations, such as an alternative storage service or different storage area within the same software defined storage network. bill branan suggested a similar approach in his cloud native preservation presentation at ndsa digital preservation 2019.52 advanced digital preservation activities advanced digital preservation activities in a 21st-century stack also make use of microservices for metadata extraction and file format conversion. versioning, however, relies upon features of the oxford common file layout, even though object storage often supports versioning natively. metadata extraction function-as-a-service microservices are well suited to metadata extraction, actuated upon ingest or as needed. since embedded metadata is machine-readable, this activity will not be resource intensive or time consuming. in addition to extracting metadata and storing it as discrete, sidecar files, these microservices can be used to populate specific metadata fields used by the repository, including descriptive, administrative, and technical metadata. this approach is more efficient as it gives flexibility to reuse the functions in multiple workflows as opposed to specific events like ingest. file format conversion file format conversions use a combination of function-as-a-service and container-based microservices, depending upon the original format. like metadata extraction, conversion may occur at ingest (normalization) or as needed (migration). function-as-a-service is well suited for small to medium files, such as converting wordperfect to opendocument format. function-as-aservice is also well suited for logical preservation, when only the informational content is necessary to preserve, such as converting a tif to a txt file through ocr. container-based microservices are better suited for converting large media files that may take more memory and time; function-based services often have a time constraint, for example, migrating proprietary encoded digital video to open codecs and container formats. versioning although object storage typically supports versioning, it is inefficient because each version is an entirely new object. this means that unchanged data is duplicated, taking up more disk space. the oxford common file layout, which negotiates storage between the application and microservices information technology and libraries december 2021 a 21st century technical infrastructure | tallman 14 layers and a software defined storage service, supports a forward delta versioning in which each new version only contains the changes. using the object inventories, it’s possible to rebuild any object to any version without duplicating bits.53 an additional benefit of using ocfl is that it inherently uses checksums, and any changes or corruption are detected when an interaction occurs with the object, creating a layered approach to maintaining fixity-at-rest. sustainability in the 21st-century stack the differences between our 20thand 21st-century stacks result in a more sustainable approach to digital preservation, per the triple-bottom-line definition.54 by adopting commercial sector approaches, cultural heritage organizations can more efficient data centers consumers. people (labor) by shifting activities to lower levels in the stack and letting infrastructure components selfmanage, fewer people are needed to develop and maintain the business logic that formerly handled the same action. the application and microservice layers use programming languages and libraries that can become outdated quickly, requiring development work to maintain functionality. while there is still a need for specialized knowledge, fewer people are needed to do the work when these actions take place in more stable parts of the stack. planet (environmental) our new stack has a lower environmental impact for a variety of reasons. first, per kryder’s law (the storage parallel to moore’s law for computing), the areal density of storage media predictably increases annually, and our new stack uses the latest hard disk and tape technology.55 this results in needing less media, some of which doesn’t need power to run, decreasing the carbon impact. additionally, our new stack uses a mix of hot and cold storage, making it possible to implement automatic tiering to shift objects to less resource-intensive storage, like tape.56 second, as the stack becomes more serverless, fewer computational resources are needed. even though container and function-based microservices may incur some overhead in terms of cpu cycles, it is more efficient in terms of system idling to be running these as microservices on one platform rather than doing the same action in the application or vm layer. this further decreases the carbon impact and while also decreasing the dependency on rare-earth elements. relatedly, by leveraging software-defined storage to maintain fixity-at-rest, the compute load is greatly decreased; the cpu cost to calculating checksums in the storage layer is less than when this is done in the through applications or microservices. profit (economic) sustainability improvements for both people and planet may also result in a lower total cost of ownership for a digital preservation system. cost is a prime motivator when administers and leaders make long term decisions, decreasing annual operating cost related to digital preservation is crucial to the viability of a program. future and related work the 21st-century stack proposed in this paper is not the only way to increase sustainability or the only way in which digital preservation stacks will change. the planet is running out of bandwidth and will need to expand into using 5g and low-earth orbit satellite communications. new, quantum-resistant algorithms will need to be introduced as quantum computing advances.57 information technology and libraries december 2021 a 21st century technical infrastructure | tallman 15 blockchain technology introduces many possibilities. inherently, blockchain maintains fixity. the archangel project is exploring practical methods of recording provenance and proving authenticity by using a permissioned blockchain.58 blockchain is also the technology behind the interplanetary file system (ipfs), a content-addressed distributed storage network, that is in turn used by filecoin, a marketplace for an ipfs storage. small data industries is building starling, a filecoin-based application designed for cultural heritage organizations to securely store digital content.59 it’s important to note that these blockchain-based projects use a proof-of-stake model instead of a proof-of-work model, which has a significantly lower environmental impact than other blockchain implementations like the cryptocurrency bitcoin.60 while some organizations, like stanford university, may already leverage software-defined storage, most in the cultural heritage sector are not.61 the metaarchive cooperative, a nonprofit consortium for digital preservation, has begun a noteworthy project to explore using softwaredefined storage in a distributed digital preservation network. metaarchive, which currently uses lockss, is one of the few public digital preservation services that mitigates risk through organizational and administrative diversity. because members host and administer the lockss nodes that contain the replications, each copy is managed by a different set of organizational and administrative policies and often use different technology to do so. diversifying in this way protects against a single point of failure if only one organization managed the technical infrastructure. how this same diversity is achieved in a software-defined storage-based distributed digital preservation network will be a great contribution to the community. it would also be useful to study the reasons cultural heritage organizations have been so reluctant to adopt commercial sector technologies. identifying these hesitations would make it possible to create strategies that would encourage adoption of these approaches. it may simply be that when it comes to digital preservation, familiar and proven technologies provide a level of comfort. organizations may also be entrenched in custom developed solutions that are hard to move away from. conclusion digital preservation is a long-term commitment. while re-appraisal may take place, it’s inevitable that the amount of content stored in digital repositories will only increase over time. it is fiduciarily incumbent upon the cultural heritage community to examine our practices and look for better alternatives. exceptionalism ignores technological advancements made by the commercial industry, advancements that are very well suited to digital preservation. by adopting commercial industry data practices, such as software-defined storage, while simultaneously implementing innovations from within the cultural heritage community, like the oxford common file layout, it is possible to reduce the ongoing costs, resource consumption, and environmental impact of digital preservation. information technology and libraries december 2021 a 21st century technical infrastructure | tallman 16 endnotes 1 ben goldman, “it’s not easy being

example, appraisal can be the most powerful tool available to an organization to control the amount of content being preserved. despite storage vendors proclamations that storage is cheap, digital preservation is not. it is not wise nor necessary to keep every digital file. organizations will benefit from applying flexible appraisal systems that reduce the amount of content needing preservation, but also establishing different classes of preservation so the most advanced activities are only applied as needed. additionally, organizations should consider allowing lossy compression to decrease disk usage, where appropriate; compression as an appraisal choice is very similar to choosing to sample a grouping of material rather than preserving the whole. for additional information

first quarter of 2004 saw the greatest number of e-book purchases ever with more than $3 million in sales. a 2002 consumer survey found that 67 percent of respondents wanted to read e-books; 62 percent wanted access to e-books through a library. unfortunately, the large amount of information written on e-books has begun to develop myths around their use, functionality, and cost. the author suggests that these myths may interfere with the role of libraries in helping to determine the future of the medium and access to it. rather than fixate on the pros and cons of current versions of e-book technology, it is important for librarians to stay engaged and help clarify the role of digital documents in the modern library. a lthough 2000 was unofficially proclaimed as the year of the electronic book, or e-book, due in part to the highly publicized release of a stephen king short story exclusively in electronic format, the dot-com bust would derail a number of high-profile e-book endeavors. with far less fanfare, the e-book industry has been slowly recovering. in 2004, e-books represented the fastest-growing segment of the publishing industry. during the first quarter of that year, more than four hundred thousand e-books were sold, a 46 percent increase over the previous year ’s numbers.1 e-books continue to gain acceptance with some readers, although their place in history is still being determined—fad? great idea too soon? wrong approach at any time? the answers partly depend on the reader ’s perspective. the main focus of this article is the role of e-book technologies in libraries. libraries have always served as repositories of the written word, regardless of the particular medium used to store the words. from the ancient scrolls of qumran to the hand-illuminated manuscripts of medieval europe to the familiar typeset codices of today, the library’s role has been to collect, organize, and share ideas via the written word. in today’s society, the written word is increasingly encountered in digital form. writers use word processors; readers see words displayed; and researchers can scan countless collections without leaving the confines of the office. for self-proclaimed book lovers, the digital world is not necessarily an ideal one. emotional reactions are common when one imagines a world without a favorite writing pen or the musty-smelling, yellowed pages of a treasured volume from youth. one of the battle lines between the traditional bibliophile and the modern technologist is drawn over the concept of the e-book. some see this digital form of written word as an evolutionary step beyond printed texts, which have been sometimes humorously dubbed tree-books. although a good deal of attention has been generated by the initial publicity regarding newer e-book technologies, the apparent failures of most of them has begun to establish myths around the concept. abram points out that the relative success of e-books in niche areas (such as reference works) is in direct contrast with public opinion of those purchasing novels and popular literature through traditional vendors.2 crawford paraphrases lewis carroll in describing this confusion: “when you cope with online content about e-books, you can believe six impossible things before breakfast.”3 incidentally, this article will attempt to dispel a mere five of the myths about e-books. the future of e-books and the critical role of libraries in this future are best served by uncovering these myths and seeking a balanced, reasoned view of their potential. a 2002 consumer survey on e-books found that 67 percent of respondents wanted to read an e-book, and 62 percent wanted that access to be from a library.4 underlying this position is the assumption that the ideas represented by the written word are of paramount importance to both writers and readers. it is also assumed that libraries will continue their critical role in collecting, organizing, and sharing information. � myth 1—e-books represent a new idea that has failed many libraries have invested in various forms of e-book delivery with mixed results.5 sottong wisely warns of the premature adoption of e-book technology, which he dubs a false pretender as a replacement to printed texts.6 however, the last five years are but a small part of a longer history, and presumably, a still longer future as is often the case with computer jargon, the term e-book has emerged and gained currency in a very short amount of time. however, the concept of providing written texts in an electronic format has existed for a long time, as demonstrated by bush’s description of the dispelling five myths about e-books james e. gall james e. gall (james.gall@unco.edu) is assistant professor of educational technology at the university of northern colorado, greeley. dispelling five myths about e-books | gall 25 26 information technology and libraries | march 2005 memex.7 the gutenberg project put theory into practice by converting traditional texts into digital files as early as 1971.8 even if the e-book merely represents the latest incarnation of the concept, it does so tenuously. books in their present form have a history of hundreds of years, or thousands if their parchment and papyrus ancestors are included. this history is rich with successes and failures of technology. for example, petroski presents an interesting historical examination of the problem of storing books when the one book–one desk model collapsed under the proliferation of available texts.9 similarly, a determination on the success or failure of e-books, or digital texts, based upon a relatively short period of time, is fraught with difficulty. rather, it is important to look at recent developments as merely a next step. the technology is clearly not ready for uncritical, widespread acceptance, but it is also deserving of more than a summary dismissal. � myth 2—e-books are easily defined the term e-book means different things depending on the context. at the simplest, it refers to any primarily textual material that is stored digitally to be delivered via electronic display. one of the confusing aspects of defining ebooks is that in the digital world, information and the media used to store, transfer, and view it are loosely coupled. an e-book in digital form can be stored on cd–rom or any number of other media and then passed on through computer networks or telephone lines. the device used to view an e-book could be a standard computer, a personal digital assistant (pda), or an e-book reader (the dedicated piece of equipment on which an e-book can be read; confusingly, also referred to as an e-book). technically, virtually any computing device with a display could be used as an e-book reader. from a practical point of view, our eyes might not tolerate reading great lengths of text on a wireless phone, and banks will not likely provide excerpts of chaucer during atm transactions. another important factor in defining e-books is the actual content. a conservative definition is that an e-book is an electronic copy or version of a printed text. this appears to be the predominant view of publishers. purists often maintain that a true e-book is one that is specifically written for that format and not available in traditional printed form.10 this was one of the categories of the shortlived (2000–2002) frankfurt e-book awards. of course, the multitude of textual materials that could be delivered via the technology exceeds these definitions. magazines, primary-source documents, online commentaries and reviews, and transcripts of audio or video presentations are just a short list of nonbook materials that are finding their way into e-book formats. one can note with some sense of irony that the technology behind the web was originally designed as a way for scientists to disseminate research reports.11 despite the web’s popularity, reading research reports makes up an exceedingly small percentage of its use today. although there is a continuing effort to reach a common standard for e-books (see www.openebook.org/), the current marketplace contains numerous noncompatible formats. this noncompatibility is the result of both design and competitive tradeoffs. in the case of the former, there is a distinct philosophical difference between formats that attempt to retain the original look and navigation of the printed page (such as adobe’s popular pdf files) versus those that retain the text’s structure but allow variability in its presentation (as best exemplified by the free-flowing nature of texts presented as html pages). this difference can also be seen in the functionality built around the format. traditional systems provide readers with familiar book characteristics such as a table of contents, bookmarks, and margin notes, a view that could be named bibliocentric. the alternative is one that takes more advantage of the new medium and could be labeled technocentric, and can most easily be seen in the extensive use of hyperlinking.12 the simplest use of hyperlinking provides an easy form of annotating texts and presenting related texts. on the other extreme, hyperlinks are used in the creation of nonlinear texts in which the followed links provide a unique context for building meaning on the part of the reader.13 it is interesting to note that a preliminary study of e-book features found that the most desirable features tended to reflect the functionality of traditional books and the least desirable features provided functionality not found there.14 competitive tradeoffs are a critical issue at the current point of e-book development. the current profit models of publishing entities and copyright concerns of authors seem naturally opposed to e-book formats in which texts were freely shared, duplicated, and distributed. for example, the open ebook forum is the most prominent organization devoted to the development of standards for e-book technologies. in late 2004, their web site listed seventy-six current members. although the american library association is a member, it is one of only six members representing library-oriented organizations. in comparison, thirty-five members (or 46 percent) are publishing organizations, and thirteen (or 17 percent) are technology companies.15 the number of traditional publishers versus technology companies on this list may suggest that a bibliocentric view of ebooks would be more favored. this also appears to confirm one media prediction that traditional publishers would continue to dominate efforts with this new medium.16 however, the limited representation of libraries in this endeavor is troubling (despite the disclaimer of using an admittedly rough metric for measuring impact). it is clear that many industry formats attempt to limit the ability to distribute materials by keying files so that they may only be viewed on one device or a specific installed version of the reader software. this creates technological problems for entities like libraries that attempt to provide access to information for various parties. the concept of fair use of copyrighted materials has to be reexamined under an entirely new set of assumptions. another irony is that the availability of free, public-domain materials in e-book format can be viewed as negative by the publishing industry. after investing considerable time and effort in developing e-book technology, publishers would prefer that users continue purchasing new e-book material rather than spend time reading the vast library of free historical material. many of these content issues are currently being played out in courts and the marketplace, particularly with regard to digital music and video.17 although one can humorously imagine the so-called problems associated with a population obsessed with downloading and reading great literature, the precedents set by these popular media will have a direct impact on the future of digital texts. despite the labor required to scan or key entire print books into digital formats, there have been some reports of this type of piracy.18 other models for the dissemination of digital intellectual property that are not determined by traditional material concerns of supply and demand will continually be attempted. for example, nelson predicted a hypertext-publishing scheme in which all material was available, but royalties were distributed according to actual access by end users.19 theoretically, such a system would provide a perfect balance between access and profitability. in nelson’s words “nothing will ever be misquoted or out of context, since the user can inquire as to the origins and native form of any quotation or other inclusion. royalties will be automatically paid by a user whenever he or she draws out a byte from a published document.”20 � myth 3—e-books and printed books are competing media many, if not most, published articles regarding e-books follow classic plot construction; the writer must present a protagonist and an antagonist. bibliophiles place the printed page as the hero and the e-book as the potential bane of civilization. proulx, one such author, was quoted as saying, “nobody is going to sit down and read a novel on a twitchy little screen—ever.”21 technologists cast the e-book as the electronic savior of text, replacing the tired tradition of the printed word in the same way the printed word replaced oral traditions. hawkins quotes an author who claims that e-books are “a meteor striking the scholarly publication world.” his slightly more restrained view was that e-books had the potential “to be the most far-reaching change since gutenberg’s invention.”22 grant places this metaphorical battle at the forefront by titling an article “e-books: friend or foe?”23 before deciding which side to take, consider whether this clash of media is an appropriate metaphor. this author has introduced samples of current ebook technology in graduate classes he has taught. when presented with the technology as part of the coursework, students quickly declare their allegiances. bibliophiles most often suggest that the technology will never replace the love of curling up with a good book. the technologists will ask how many pages can be stored in the device and then fantasize about the types of libraries they can carry and the various venues for reading that they will explore. however, after a few weeks in using the devices, both groups tend to move to a middle ground of practical use. at that point, the discussion turns to what materials are best left on the printed page (usually described as pleasure reading) and what would be useful in e-book format (reference works, course catalogs, how-to manuals). other instructors have reported similar patterns of use.24 at this point, the observation is largely anecdotal, but it does call into question the perceived need for a decisive referendum on the value of e-books. the issue is not whether e-books will replace the printed word. the concern of librarians and others involved in the infrastructure of the book should be on developing the proper role for e-books in a broader culture of information. unless this approach is taken, the true goal of libraries—disseminating information to the public—will suffer. the gap between bibiliophile and technologist approaches can already be seen in the materials available in e-book format. the publishing industry in general treats the e-book as just another format, releasing the same titles in hardcover, book-on-tape, and e-book at the same time. on the opposite end of the spectrum, technologists have adopted various e-book formats for creating and transferring numerous reference documents. given their preferences, it is easy to find e-book references on unix, html coding, and the like, but there is a scarcity of materials in philosophy, history, and the arts. librarians seem the most appropriate group for developing shared understanding. publishers and e-book hardware and software manufacturers need to be concerned with the bottom line. libraries, by design, are concerned with the preservation of information and its continued dissemination long after the need to sell a particular book has passed. the hobby of creating and transferring texts to digital form is idiosyncratic and unorganized when viewed from the highest levels. libraries not only contain expertise in all areas of human endeavor, but also have strategies for categorizing and maintaining information in productive ways. in short, libraries are the best line of defense for maintaining the value of the printed page and promoting the value of digital texts. dispelling five myths about e-books | gall 27 28 information technology and libraries | march 2005 � myth 4—e-books are expensive a common complaint about e-books is that they are expensive. on the surface, this seems clear. dedicated ebook readers seemed to bottom out at around $300, and a new bestseller in e-book format is priced about the same as the hardcover edition. add the immediate and longterm costs of rechargeable batteries and the electricity needed to power them, and the economic case against the e-book appears closed. what if we turn the same critical eye to the printed page? the manufacture and distribution of printed texts is highly developed and astounding. when gutenberg succeeded in putting the christian bible in the hands of the moneyed public, he surely could not have comprehended the billions of copies that would eventually be distributed. even with the wealth of printed material at hand, one must still consider the high cost of the system. the law of supply and demand rules books as a tangible product. the most profitable books are those that will reach the most readers. specialized texts have limited audiences and, therefore, will usually be priced higher. this produces problems for both groups. popular texts must be printed in high quantities and delivered to various outlets. unfortunately, the printed page does have maintenance costs. sellen and harper point out that the actual printing cost is insignificant compared with the cost of dealing with documents after printing. they cite one study that indicated that united states businesses spend about $1 billion per year designing and printing forms, but spend an additional $25 to $35 billion filing, storing, and retrieving them.25 books are no different; as any librarian knows, it costs money to maintain a collection and protect texts from the environment and the effects of age. in the retail arena, the competition is fiercer. books that do not sell are removed in favor of those that do. it is estimated that 10 percent of texts printed each year are turned to pulp, although, fortunately, many are recycled.26 the bbc reported that more than two million former romance novels were used in the construction of a new tollway.27 with more specialized texts, the problem is not wealth, but scarcity. if a text is not profitable, it will probably become out of print. this is often synonymous with inaccessible. from the publisher’s perspective, it is only cost-effective to commit to a printing when the demand is high enough. a library is a good source of outof-print texts, provided that it has been funded appropriately to acquire and maintain the particular works that are needed. e-books are not a panacea. other innovations, such as on-demand publishing, may be part of the answer in solving the economic issues regarding collections. however, e-books can help alleviate some of these issues. e-books are easily copied and distributed, which is a boon to the researcher and information consumer. in many cases, the goal is the access to information, not the possession of a book. it could also benefit the author and publisher if appropriate reimbursement systems are put into place. as previously described, nelson originally envisioned his online hypertext system, xanadu, with a mechanism for royalties based on access—a supply-anddemand system for ideas, not materials.28 the systems used to manage access to digital materials continue to increase in complexity and have spawned a whole new business of digital rights management (drm).29 examples include reciprocal (www.reciprocal.com), overdrive (www.overdrive.com), and netlibrary (www.net library.com). libraries are the specific target of netlibrary, which promotes an e-books-on-demand project that allows free access for short periods of time.30 the creation of a standard digital object identifier (doi) for published materials may also help online publishers and entities like libraries manage their digital collections more easily.31 online music systems, such as apple’s itunes (www. itunes.com), strike a workable balance between quickand-easy access to music and a workable, economic model for reimbursing artists. e-books also have appeal for special audiences who already require assistive technologies for accessing print collections.32 having discussed the hidden costs of printed texts, another important economic issue of e-books to examine is a current trend in usage. despite the availability of dedicated e-book readers, the largest growth in e-book usage is surely in nondedicated devices. e-book–reading software is available for personal computers, laptops, and pdas. according to one source, microsoft had sold four million pocketpc e-book-enabled devices, and had two million downloads of the ms reader for the personal computer; palm had sold approximately 20 million ebook-enabled devices; and adobe had more than 30 million acrobat readers downloaded.33 these numbers alone indicate some 24 million reader-capable pdas, and 32 million reader-capable pcs, for a total of 56 million devices. although it is difficult to find data on actual use, one online bookseller reported some data on e-book use from an audience survey.34 although 88 percent had purchased books online, only 16 percent had read an e-book (11 percent using a pc, 3 percent on a handheld device, and 2 percent on both). it is presumed that in most cases this equipment was purchased for other reasons, with ebook reading being a secondary function. as such, it would be unfair to include the full cost of this equipment in any calculation of the cost of providing information in an e-book format. if so, the cost of providing artificial lighting in any building where reading takes place would need to be calculated as part of the cost of the printed page. the potential user base for the e-book rises as more computers and pdas are sold, decreasing the need for special equipment. this does not mean that the dedicated e-book reader is obsolete. by most commercial accounts, the apple newton was a failure. its bulky size and awkward interface were the subject of much ridicule. however, it did introduce the concept of the pda. the success of the palm line of products owes much to the proof of concept provided by the newton. the makers of the portable gameboy videogame system are repositioning it for multimedia digital-content delivery, and plan to pilot a flash-memory download system for various content types, including e-books.35 innovative products such as e-paper are already developed in prototype form.36 they are likely to lead to another wave of dedicated e-book readers or provide e-book–reading potential embedded in other consumer applications. � myth 5—e-books are a passing fad it is trendy to list the failures of past media (such as radio, film, and television) in impacting education despite great initial promise.37 however, all those media are still with us after having found particular niches within our culture. if the e-book is viewed as just an alternative format, comparisons with past experiences of library collections containing videotapes, record albums, and such are not appropriate.38 however, if e-books are viewed as a tool or way to access information, the questions change. instead of asking how digital formats will replace print collections, we can ask how will an e-book version extend the reach of our current collection or provide our readers with resources previously unavailable or unaffordable. when trying to locate a research article, one is generally not concerned with whether the local library has a loose copy, bound copy, microform, microfiche, or even has to resort to interlibrary loan. as long as the content is accessible and can be cited, it can be used. electronic access to journal content is becoming more common. perhaps dry journal articles do not conjure up the same romantic visions of exploring the stacks that may hinder greater acceptance of e-books. a parallel can be drawn to the current work of filmrestoration experts. the medium of film has reached an age where some of the earliest influential works no longer exist or are in a condition of rapid deterioration. according to one film site, more than half of the films made before 1950 have already been lost due to decay of existing copies.39 the work of restoration involves finding what remains of a great work in various vaults and collections. often, the only usable film is a secondor third-generation copy. from digitized copies, cleaning, color correction, and other painstaking work, a restored and—it is hoped—complete work emerges. ironically, once this laborious process is completed, a near-extinct classic is suddenly available to millions in the form of a dvd disc at a local retailer. what if the same attitude was taken with the world’s collections of printed materials? jantz has described potential impacts of e-book technology on academic libraries.40 lareau conducted a study on using e-books to replace lost books at kent state university, but found that limited availability and high costs did not make it feasible at the time.41 project gutenberg (www.gutenberg.net) and the electronic text center at the university of virginia (http://etext.lib.virginia.edu) are two examples of scholars attempting to save and share book content in electronic forms, but more efforts are needed. unfortunately, the shift to digital content has also contributed to the sheer volume of content available. edwards has recently discussed issues in attempting to archive and preserve digital media.42 the web may be suffering from a glut of information, but the content is highly skewed toward the new and technology oriented. in a few years, we may find that nontechnology–related endeavors are no longer represented in our information landscape. � conclusion the e-book industry is currently dominated by commercial-content providers, such as franklin, and software companies, most notably adobe, palm, and microsoft. traditional print-based publishers have also maintained continued interest in the medium. it is assumed that these publishers had the capital to weather the ups and downs of the industry more so than new publishers dedicated solely to e-book delivery. although the contributions and efforts of these organizations are needed, the future of e-book content should not be left to their largesse. when the rocket e-book device was initially released, a small but loyal following of readers contributed thousands of titles to its online library. some of these titles were self-published vanity projects or brief reference documents, but many were public-domain classics, painstakingly scanned or keyed in by readers wishing to share their favorite reads. when gemstar purchased rocket, the software’s ability to create non-purchased content was curtailed and the online library of free titles dismantled. apparently, both were viewed as limiting the profitability of the e-book vendor. however, gemstar recently made notice of discontinuing their e-book reading devices, one would assume due to a lack of profitability. this can be seen as a cautionary tale for libraries, which often define success by number of volumes available and accessed rather than units sold. committing to a technology that concurrently requires consumer success can be problematic. bibliophile and technologist alike must take responsibility for the future of our collective information resources. the bibliophile must ensure that all aspects of dispelling five myths about e-books | gall 29 30 information technology and libraries | march 2005 human knowledge and creativity are nurtured and allowed to survive in electronic forms. the technologist must ensure that accessibility and intellectual-property rights are addressed with every technological innovation. parry provides three concrete suggestions for public libraries in response to new media demands: continue to acknowledge and respond to customer demands, revisit the library’s mission statement for currency, and promote or accelerate shared agreements with other institutions to alleviate the high costs of accumulating resources.43 the proper frame of mind for these activities is suggested by levy: we make a mistake, i believe, when we fixate on particular forms and technologies, taking them in and of themselves, to be the carriers of what we want to embrace or resist. . . . it isn’t a question, it needn’t be a question, of books or the web, of letters or e-mail, of digital libraries or the bricks-and-mortar variety, of paper or digital technologies. . . . these modes of operation are only in conflict when we insist that one or the other is the only way to operate.44 in the early 1930s, lomax dragged his primitive audio-recording equipment over the roads of the american south to capture the performances of numerous folk musicians.45 at the time, he certainly didn’t imagine that at one point in history someone with a laptop computer sitting in a coffee shop with wireless access could download the performances of robert johnson from itunes. however, without his efforts, those unique voices in our history would have been lost. it is hoped that the readers of the future will be thanking the library professionals of today for preserving our print collections and enabling their access digitally via our primitive, but evolving, e-book technologies. references 1. open e-book forum, “press release: record e-book retail sales set in q1 2004,” june 4, 2004. accessed dec. 27, 2004, www.openebook.org. 2.

ala annual conference. this past fall, michelle frisque, lita web manager, conducted a survey of our members about the lita web site. michelle and the web coordinating committee are already working on a new look and feel for the lita web site based on the survey comments, and the result promises to be phenomenal. on top of all of the current activities, new vision statement, strategic planning, and the lita web site redesign, mary taylor and the lita board worked with a graphic designer to develop a new lita logo. after much deliberation, the new logo debuted at the 2004 lita national forum with great enthusiasm. many members commented that the new logo expresses the “energy” of lita and felt the change was terrific. with your help, lita had a very successful conference in orlando. although there were weather and transportation difficulties, the lita programs and discussions were of the highest quality, as always. the program and preconference offerings for the upcoming annual conference in chicago promise to be as strong as ever. don’t forget, lita also offers regional institutes throughout the year. check the lita web site to see if there’s a regional institute scheduled in your area. lita held another successful national forum in fall 2004 in st. louis, “ten years of connectivity: libraries, the world wide web, and the next decade.” the threeday educational event included excellent preconferences, general sessions, and more than thirty concurrent sessions. i want to thank the wonderful 2004 lita national forum planning committee, chaired by diane bisom, the presenters, and the lita office staff who all made this event a great experience. the next lita national forum will be held at the san jose marriott, san jose, california, september 29–october 2, 2005. the theme will be “the ubiquitous web: personalization, portability, and online collaboration.” thomas dowling, chair, and the 2005 lita national forum planning committee are preparing another “must attend” event. next year marks lita’s fortieth anniversary. 2006 will be a year for lita to celebrate our history, future, and our many accomplishments. we are fortunate to have lynne lysiak leading the fortieth anniversary task force activities. i know we all will enjoy the festivities. i look forward to working with many of you as we continue to make lita a wonderful and vibrant association. i encourage you to send me your comments and suggestions to further the goals, services, and activities of lita. 32. terence cavanaugh, “e-books and accommodations: is this the future of print

government documents round table's (godort) machinereadable data file committee, the federal librarians round table (flirt), the rasd information retrieval committee, and the rasd/rtsd/ asla public documents committee. the moderator is gretchen dewitt of columbus public library and the panelists are peter watson of ucla, mary pensyl of mit, judith rowe of princeton, and billie salter of yale. mr. watson will discuss the general issues concerning the acquisition and use of bibliographic data files and provide a brief description of some of the files now publicly available; miss pensyl will describe the workings of the project now underway to make these files available to mit users. mrs. rowe will discuss the ways in which government-produced statistical files supplement the related printed reports and will indicate some of the types and sources of files now being released; miss salter will discuss a program for integrating these and other research files into yale's social science reference service. representatives of several federal agencies will display materials describing and documenting both bibliographic and statistical data files. the purpose of the program is to acquaint reference librarians, particularly those now handling printed documents, with the uses of both types of files, the advantages and disadvantages of these reference tools, and the techniques and policy changes necessary for their use in a library environment. the recent release of the draft proposal produced by the national commission on libraries and information services makes more timely than ever an open discussion of the place of bibliographic and numeric data files in a reference collection. all librarians must be acquainted with these growing resources in order to continue to provide full service to their patrons. for further information, contact judith rowe, computer center, princeton university, 87 prospect ave., princeton, nj 08540. ninth annual educational media and

final report of a project sponsored by lc, the council on library resources, inc., and the u.s. office of education to determine the problems associated with centralized conversion of retrospective catalog records and distribution of these records from a central source. in the marc pilot project, begun in november 1966, the library of congress distributed machine-readable catalog records for english-language monographs, and the success of that project led to the implementation in march 1969 of the marc distribution service, in which over fifty subscribers have by now received more than 300,000 marc records representing the current english-language monograph cataloging at the library of congress. as coverage is extended to catalog records for foreign-language monographs and for other forms of material, libraries will be able to obtain machine records for a large number of their current titles. more research was needed, however, on the problems of obtaining machinereadable data for retrospective cataloging, and the council on library resources made it possible for lc to engage in november 1968 a task force to study the feasibility of converting retrospective catalog records. the final report of the recon (for retrospective conversion) working task force was published in june 1969. one of the report's recommendations was that a pilot project test various conversion techniques, ideally covering the highest priority materials, english-language monograph records from 1960-68; and with funds from the sponsoring agencies lc initiated a two-year project in august 1969. the present report covers five major areas examined in that period: 1. testing of techniques postulated in the recon report in an operational environment by converting englishlanguage monographs cataloged in 1968 and 1969 but not included in the marc distribution service. 2. development of format recognition, a computer program which can process unedited catalog records and supply all the necessary content designators required for the full marc record. 3. analysis of techniques for the conversion of older english-language materials and titles in foreign languages using the roman alphabet. 4. monitoring the state-of-the-art of input devices that would facilitate conversion of a large data base. 5. a study of microfilming techniques and their associated costs. recon pilot project is

national aspects of creating and using marc/recon records (v, 48p.) reports on studies conducted at the library of congress by the recon working task force under the chairmanship of henriette d. avram. they were made concurrently with a pilot project by the library to test the feasibility of the plan outlined in the task force's first report entitled conversion of retrospective reco1·.ds to machine-readable form (library of congress, 1969) and in recon pilot p1'oject (library of congress, 1972). both the pilot project and the new studies received financial support from the council on library resources, inc., and the u.s. office of education. the present volume describes four investigations: ( 1) the feasibility of determining a level or subset of the established marc content designators (tags, indicators, and subfield codes) that would still allow a library using it to be part of a future national network; ( 2) the practicality of the library of congress using other machine-readable data bases to build a national bibliographic store; ( 3) implications of a national union catalog in machine-readable form; and ( 4) alternative strategies for undertaking a largescale conversion project. the appendices include an explanation of the problems of achieving a cooperatively produced bibliographic data base, a description of the characteristics of the present national union catalog, and an analysis of library of congress card orders for one year. although the findings and recommendations of this report are less optimistic than those of the original recon study, they reaffirm the need for coordinated activity in the conversion of retrospective catalog records and suggest ways in which a large-scale project might be undmtaken. the report provides a basis for realistic planning in a critical area of library automation. national aspects of creating and using marc!recon records is available for $2.75 from the superintendent of documents, u.s.

california-the national science foundation has awarded system development corporation $98,500 for a study of man-machine system communication in on-line reh·ieval systems. the study will focus on interactive searching of very large literature data bases, which has become a major area of interest and activity in the field of information science. at least seven major systems of national or international scope are in operation within the federal government and private industry, and more systems are on the drawing boards or in experimental operation. the principal investigator for the project will be dr. carlos cuadra, manager of sdc's education and library systems department. the project manager, who will be responsible for the day-to-day operation of the fifteen-month effort, is judy wanger, an information systems analyst and project leader with extensive experience in the establishment and use of interactive bibliographic retrieval services. ms. wanger is currently responsible for user training and customer support on sdc's on-line information service. the study will use questionnaire and interview techniques to collect data re144 journal of libml'y automation

the information-utilization habits of the information consumer. attention will also be given to reliability problems in the transmission chain from the user to the computer and back. the major elements in this chain include: the user; the terminal; the telephone instrument; local telephone lines and switchboards; long-haul communications; the communications-computer interface hardware; the computer itself; and various programs in the computer, including the retrieval program. reports on regional projects and activities california state university and colleges system union list system the library systems project of the california state university and colleges has recently completed a production union list system. this system, comprised of eight processing programs to be run in a very modest environment (currently a cdc 3300), is written in ansi cobol and is fully documented. included in the documentation package are user worksheets for bibliographic and holding data, copies of all reports, file layouts, program descriptions, etc. output from this system are files designed to drive graphic quality photocomposition or com devices. the system is available for the price of duplicating the documentation package. and, for those so desiring, the master file containing some 25,000 titles and titles with references is also available for the cost of duplication. interested parties (bona fides only, please) should contact john c. kountz, associate for library automation, california state university and colleges, 5670 wilshire blvd., suite 900, los angeles, ca 90036, for

announced that charles h. stevens, executive director of the national commission on libraries and information science, has been named director of solinet effective july 1. john h. gribbin, chairman of the board, will serve as interim director. it was also announced that solinet will be affiliated with the southern regional education board. sreb will provide office space, act as financial disbursing agent, and will be available at all times in an advisory capacity. negotiations are underway for a tie-in to the ohio college library center ( oclc) and a proposed contract is in the hands of the oclc legal counsel. it is anticipated that a contract soon will be signed. additional to the tie-in, solinet will proceed with the development of its own permanent computer center in atlanta. this center will eventually provide a variety of services and will be coordinated carefully with other developing networks, looking toward a national library network system. elected to fill three vacancies on the board of directors were james f. govan (university of north carolina), gustave a. harrar (university of florida), and robert h. simmons (west georgia college). they will assume office on july 1.

three community college libraries of the junior college district of st. louis have been using computerized union book catalogs since 1964. formerly maintained and produced by an outside contractor, the catalogs are now one product of a new catalog system recently designed and implemented by instructional resources and data processing staff of the district. known as "ir catalog," the system presently has a data base of approximately 65,000 records describing the print and nonprint collections of the district's three college instructional resource centers. in addition to photocomposed author, subject, and title indexes, the system also produces weekly cumulative printouts which supplement the phototypeset ''base" catalog. other output includes three-by-five-inch shelflist cards (which include union holdings information), a motion picture film catalog, subject and cross reference authority lists, and various statistical reports. hawaii state lihra1'y system to automate p1'ocessing the state board of education in hawaii has approved a proposal for a computerized data processing system for the hawaii state library. the decision allows for the purchase of computer equipment for automating library operations. the state library centrally processes library materials for all public and school libraries in the state. teichior hirata, acting state education superintendent, told board members a computerized system will speed book selection, ordering, and processing, and will improve interlibrary loan and reference services. he also pointed out it would facilitate a general streamlining of all technical administrative operations. the system's total cost will be $187,000, of which $58,000 will be spent for computer software. the "biblios" system, designed and developed at orange county public library in california and marketed by information design, inc., was selected as the software package. the caltech science lihm1'y catalog supplement the use of catalog supplements during the necessary maturation period required to take full advantage of the national program for acquisitions and cataloging is technical communications 145 obviously an

for reasons based primarily on faculty pressure, the practice of holding books in anticipation of the cataloging copy has never been a practice at the institute. the solution, while hardly unique, is to assign the classification number (dewey) and depend on a temporary main entry card to suffice until the lc copy is available. while this procedure has the distinct advantage of not requiring the presence of the book to complete the cataloging process, it does, however, prevent the user from finding the newest books through a search of the subject added entry cards. the use of the computer-based systems is an obvious solution to this aspect of the program but raises several additional problems which formerly seemed to defy solutions. as has been pointed out by mason, library-based computer systems can rarely be justified in terms of cost effectiveness, and computer-based library catalogs are no exception.2 part of this problem arises from the natural inclination to repeat in machine language what has been standard practice in the library catalog. this reaction overlooks the very different nature of catalogs and catalog supplements. as catalogs serve as the basis for the permanent record and their cost can be prorated over several decades the need for a careful description of the many facets of a book is quite properly justified. in the case of catalog supplements, however, where the record will serve quite likely for only a few months, any attempt at detailed description of the book cannot be justified. one solution to this dilemma that has been developed here at caltech is a brief listing supplement which allows searching for a given book by either the first author or editor's last name, a key word from the title, or the first word of a series entry. these elements form the basis of a simple kwoc index (see figure 1) which sup146 journal of library automation vol. 7/2 june 1974 chemisorption chemisorption and catalysis hepple 541.395

represented in the catalog supplement. weekly lists of newly added books (shown in figure 3) are annotated to show the index terms prior to keypunching. the unit record consists of a "title" card or cards (which contain the full title, author/ editor, call number, library designation, and series information) and an "author" card (which contains the index terms) . edited material is added accessionally to the card file data base and batch processed on the campus ibm 370/ 155 computer. the catalog supplement is currently published on 8jf-by-1hnch sheets as a result of reducing the computer printout on a xerox 7000 copier. lists are given a vello-bind and delivered to therespective libraries. weeding the catalog supplement is still unresolved. at the present time additions are less than 1,000 per year, so that it may be possible after five years to replace the subject sections of the respective divisional catalogs with the catalog supplement. the "library" at caltech consists of several divisional libraries, each with their own card catalog. these divisional card catalogs are supplemented by a union catalog, which serves all libraries on campus and, because of the strong interdisciplinary nature of the divisional libraries, is much the better source for subject searches. the project is so facile and the costs so minimal that this approach might be of value to many small libraries. it is particularly applicable to the problems recently discussed by patterson. 3 books in series, even if they are distinct monographs, are often lost to the user from a subject approach. with this system each physical volume added to the library can be analyzed for possible inclusion in the catalog supplement. 1. robertanixon and ray bell, "the u.c.l.a. library catalog

one of the most effective forms of continuing education is state-of-the-art reporting. recognizing the need for more such communication 1 the international library service firm of richard abel & company plans to sponsor two workshops for the library and information science community. the first workshop will deal with the latest techniques in library automation. it will precede the 197 4 american library association conference in new york city, july 7-13. the second will present advances in library management, and will be scheduled to precede the 1975 ala midwinter meeting, january 19-25. the workshops will include forums, lectures, and open discussions. they will be presented by recognized leaders in the fields of library automation, management, and consulting. each workshop will probably be one or two days long. there will be no charge to attend either of the workshops, but attendance will be limited, to provide a good discussion atmosphere. for the management workshop, attendance will be limited to librarians active in library management. similarly, the automation workshop is intended for librarians working in library automation. maintaining the theme of state-of-theart reporting, the basic content of the workshops will consist of what is happening in library management and automation today. looking to the future, there will also be discussions and forecasts of what is to come. persons interested in further informatechnical communications 147 tion or in pa1ticipating in either workshop should contact abel workshop director, richard abel &

libraries, has been announced by information dynamics corporation. demonstrations are planned for the ala annual conference in new york, july 7-13. according to david p. waite, idc president, "during 1973, bibnet service modules were interconnected over thousands of miles and tested for on-line use with idc's centralized computerbased cataloging data files. this is the culmination of a program that began two years ago. it is patterned after advanced technological developments similar to those recently applied to airline reservation systems and other large scale nationwide computing networks used in industry." idc, a new england-based library systems supplier, will provide a computerstored cataloging data base of more than 1.2 million library of congress and contributed entries. initially it will consist of all library of congress marc records (now numbering over 430,000 titles), plus another 800,000 partial lc catalog records containing full titles, main entries, lc card numbers, and other selected data elements. as a result, bibnet will provide on-line bibliographic searching for all 1,250,000 catalog records produced by the library of congress since 1969. to enable users to produce library cards from those non-marc records for which only partial entries are kept in the computer, idc will mail card sets from its headquarters and add the full records to the data base for future reference. subscribing libraries will have access to the data base using a minicomputer cathode ray tube (crt) terminal. using this technique of dispersed computing each bibnet terminal has programmable computer power built-in. this in-house 148 journal of library automation vol. 7/2 june 1974 processing power, independent of the central computer, allows computer processes like library card production to be performed in the library. this also eliminates waiting for catalog cards to arrive in the mail. bibnet terminals communicate with the central computer over regular telephone lines, eliminating the high costs of dedicated communication lines. therefore, thousands of libraries throughout the united states and canada can avail themselves of on-line services at low cost. bibnet users will have several methods of extracting information from the idc data base. the computer can search for individual records by titles, main entry, isbn number, or keywords. here's how it works: the operator types in any one of the search items or if a complete title is not known, a keyword from the title may be used. the cataloging information is then displayed on the crt where the operator may verify the record. at the push of a button, the data is stored on a magnetic cassette tape which is later used for editing and production of catalog cards by the user library. the bibnet demonstration in new york will highlight one of many bibliographic service modules available from idc and stress the fact that these services can be utilized by individual libraries and organized groups of libraries. license for new information retrieval concept awarded to boeing by xynetics an exclusive license for manufacture and marketing to the government sector of systems incorporating a completely new concept in information storage and retrieval has been awarded to the boeing company, seattle, washington, by xynetics, inc., canoga park, california, it was announced jointly by dr. r. v. hanks, boeing program manager, and burton cohn, xynetics board chairman. the system is said to be the first image storage and retrieval system which offers response times and costs comparable to those of digital systems. the heart of the system is a device of proprietary design, the flat plane memory, which provides mpid access to massive amounts of data stored in high resolution photographic media. the photographic medium enables low cost storage of virtually any type of source material (documents, correspondence, drawings, multitone images, computer output, etc.) while eliminating the need for time-consuming, costly conversion of pre-existing information into a specialized (e.g., digital) format. by virtue of its extremely rapid random access capability, the data needs of as many as several thousand users can be served at remote video terminals from a single memory with near real time response ( 1-3 seconds, typically). the high speed, high accuracy, and high reliability of the flat plane memory is accomplished primarily through the use of the patented xynetics positioner, which generates direct linear motion at high speeds and with great precision and reliability instead of converting rotary motion. as a result, the positioners eliminate the gears, lead screws, and other mechanical devices previously utilized, and thus achieve the requisite speed, accuracy, and reliability. the xynetics positioners are already being used in automated drafting systems produced by the firm, and in a wide variety of other applications, including the apparel industry and integrated circuit test systems. the new approach could eliminate many of the problems associated with multiple reproductions and distribution of large data files. in addition to many government applications, the system is expected to have major applications in the commercial marketplace. appointments charles h. stevens appointed solinet director charles h. stevens, executive director,

june_ita_pekala_final privacy and user experience in 21st century library discovery shayna pekala information technology and libraries | june 2017 48 abstract over the last decade, libraries have taken advantage of emerging technologies to provide new discovery tools to help users find information and resources more efficiently. in the wake of this technological shift in discovery, privacy has become an increasingly prominent and complex issue for libraries. the nature of the web, over which users interact with discovery tools, has substantially diminished the library’s ability to control patron privacy. the emergence of a data economy has led to a new wave of online tracking and surveillance, in which multiple third parties collect and share user data during the discovery process, making it much more difficult, if not impossible, for libraries to protect patron privacy. in addition, users are increasingly starting their searches with web search engines, diminishing the library’s control over privacy even further. while libraries have a legal and ethical responsibility to protect patron privacy, they are simultaneously challenged to meet evolving user needs for discovery. in a world where “search” is synonymous with google, users increasingly expect their library discovery experience to mimic their experience using web search engines.1 however, web search engines rely on a drastically different set of privacy standards, as they strive to create tailored, personalized search results based on user data. libraries are seemingly forced to make a choice between delivering the discovery experience users expect and protecting user privacy. this paper explores the competing interests of privacy and user experience, and proposes possible strategies to address them in the future design of library discovery tools. introduction on march 23, 2017, the internet erupted with outrage in response to the results of a senate vote to roll back federal communications commission (fcc) rules prohibiting internet service providers (isps), such as comcast, verizon, and at&t, from selling customer web browsing histories and other usage data without customer permission. less than a week after the senate vote, the house followed suit and similarly voted in favor of rolling back the fcc rules, which were set to go into effect at the end of 2017.2 the repeal became official on april 3, 2017 when the president signed it into law.3 this decision by u.s. lawmakers serves as a reminder that today’s internet economy is a data economy, where personal data flows freely on the web, ready to be compiled and sold to the highest bidder. continuous online tracking and surveillance has become the new normal. shayna pekala (shayna.pekala@georgetown.edu) is discovery services librarian, georgetown university library, washington, dc. privacy and user experience in 21st century library discovery | pekala https://doi.org/10.6017/ital.v36i2.9817 49 isps are just one of the many players in the online tracking game. major web search engines, such as google, bing, and yahoo, also collect information about users’ search histories, among other personal information.4 by selling this data to advertisers, data brokers, and/or government agencies, these search engine companies are able to make a profit while providing the search engines themselves for “free.” in addition to profiting off of user data, web search engines also use it to enhance the user experience of their products. collecting and analyzing user data enables systems to learn user preferences, providing personalized search results that make it easier to navigate the ever-increasing sea of online information. the collection and sharing of user data that occurs on the open web is deeply troubling for libraries, whose professional ethics embody the values of privacy and intellectual freedom. a user’s search history contains information about a user’s thought process, and the monitoring of these thoughts inhibits intellectual inquiry.5 libraries, however, would be remiss to dismiss the success of web search engines and their use of data altogether. mit’s preliminary report on the future of libraries urges, “while the notion of ‘tracking’ any individual’s consumption patterns for research and educational materials is anathema to the core values of libraries...the opportunity to leverage emerging technologies and new methodologies for discovery should not be discounted.”6 this article examines the current landscape of library discovery, the competing interests of privacy and user experience at play, and proposes possible strategies to address them in the future design of library discovery tools. background library discovery in the digital age the advent of new technologies has drastically shaped the way libraries support information discovery. while users once relied on shelf-browsing and card catalogs to find library resources, libraries now provide access to a suite of online tools and interfaces that facilitate cross-collection searching and access to a wide range of materials. in an online environment, many paths to discovery are possible, with the open web playing a newfound and significant role. today’s library discovery tools fall into three categories: online catalogs (the patron interface of the integrated library system (ils)), discovery layers (a patron interface with enhanced functionality that is separate from an ils), and web-scale discovery tools (an enhanced patron interface that relies on a central index to bring together resources from the library catalog, subscription databases, and digital repositories).7 these tools are commonly integrated with a variety of external systems, including proxy servers, inter-library loan, subscription databases, individual publisher websites, and more. for the most part, libraries purchase discovery tools from third-party vendors. while some libraries use open source discovery layers, such as blacklight or vufind, there are currently no open source options for web-scale discovery tools.8 information technology and libraries | june 2017 50 outside of the library, web search engines (e.g. google, bing, and yahoo), and targeted academic discovery products (e.g. google scholar, researchgate, and academia.edu) provide additional systems that enable discovery.9 in fact, web search engines, particularly google, play a significant role in the research process. both students and faculty use google in conjunction with library discovery tools. students typically use google at the beginning of the research process to get a better understanding of their topic and identify secondary search terms. faculty, on the other hand, use google to find out how other scholars are thinking about a topic.10 unsurprisingly, google and google scholar provide the majority of content access to major content platforms.11 the data economy and online privacy concerns in an information discovery environment that is primarily online, new threats to patron privacy emerge. in today’s economy, user data has become a global commodity. commercial businesses have recognized the value of data mining for marketing purposes. bjorn bloching, et. al. explain, “from cleverly aggregated data points, you can draw multiple conclusions that go right to the heart and mind of the customer.”12 along the same lines, the ability to collect and analyze user data is extremely valuable to government agencies for surveillance purposes, creating an additional data-driven market.13 the increasing value of user data has drastically expanded the business of online tracking. in her book, dragnet nation, journalist julia angwin outlines a detailed taxonomy of trackers, including various types of government, commercial, and individual trackers.14 in the online information discovery process, multiple parties collect user data at different points. consider the following scenario: a user executes a basic keyword search in google to access an openly available online resource. in the fifteen seconds it takes the user to get to that resource, information about the user’s search is collected by the internet service provider (isp), the web browser, the search engine, the website hosting the resource, and any third-party trackers embedded in the website. the search query, along with the user’s internet protocol (ip) address, become part of the data collector’s profile on the user. in the future, the data collector can sell the user’s profile to a data broker, where it will be merged with profiles from other data collectors to create an even more detailed portrait of the user.15 the data broker, in turn, can sell the complete dataset to the government, law enforcement, commercial businesses, and even criminals. this creates serious privacy concerns, particularly since users have no legal right over how their data is bought and sold.16 privacy protection in libraries libraries have deeply-rooted values in privacy and strong motivations to protect it. intellectual freedom, the foundation on which libraries are built, necessarily requires privacy. in its interpretation of the library bill of rights, the american library association (ala) explains, “in a library (physical or virtual), the right to privacy is the right to open inquiry without having the subject of one’s interest examined or scrutinized by others.”17 many studies support this idea, privacy and user experience in 21st century library discovery | pekala https://doi.org/10.6017/ital.v36i2.9817 51 having found that people who are indiscriminately and secretly monitored censor their behavior and speech.18 libraries have both legal and ethical obligations to protect patron privacy. while there is no federal legislation that protects privacy in libraries, forty-eight states have regulations regarding the confidentiality of library records, though the extent of these protections varies by state.19 because these statutes were drafted before the widespread use of the internet, they are phrased in a way that addresses circulation records and does not specifically include or exclude internet use records (records with information on sites accessed by patrons) from these protections. therefore, according to theresa chmara, libraries should not treat internet use records any differently than circulation records with respect to confidentiality.20 the library community has established many guiding documents that embody its ethical commitment to protecting patron privacy. the ala code of ethics states in its third principle, “we protect each library user's right to privacy and confidentiality with respect to information sought or received and resources consulted, borrowed, acquired or transmitted.”21 the international federation of library associations and institutions (ifla) code of ethics has more specific language about data sharing, stating, “the relationship between the library and the user is one of confidentiality and librarians and other information workers will take appropriate measures to ensure that user data is not shared beyond the original transaction.”22 the library community has also established practical guidelines for dealing with privacy issues in libraries, particularly those issues relating to digital privacy, including the ala privacy guidelines23 and the national information standards organization (niso) consensus principles on user’s digital privacy in library, publisher, and software-provider systems.24 additionally, the library freedom project was launched in 2015 as an educational resource to teach librarians about privacy threats, rights, and tools, and in 2017, the library and information technology association (lita) released a set of seven privacy checklists25 to help libraries implement the ala privacy guidelines. personalization of online systems while user data can be used for tracking and surveillance, it can also be used to improve the digital user experience of online systems through personalization. because the growth of the internet has made it increasingly difficult to navigate the continually growing sea of information online, researchers have put significant effort into designing interfaces, interaction methods, and systems that deliver adaptive and personalized experiences.26 angsar koene, et. al. explain, “the basic concept behind personalization of on-line information services is to shield users from the risk of information overload, by pre-filtering search results based on a model of the user’s preferences… a perfect user model would…enable the service provider to perfectly predict the decision a user would make for any given choice.”27 the authors continue to describe three main flavors of personalization systems: 1. content-based systems, in which the system recommends items based on their similarity to items that the user expressed interest in; information technology and libraries | june 2017 52 2. collaborative-filtering systems, in which users are given recommendations for items that other users with similar tastes liked in the past; and 3. community-based systems, in which the system recommends items based on the preferences of the user’s friends.28 many popular consumer services, such as amazon.com, youtube, netflix, google, etc., have increased (and continue to increase) the level of personalization that they offer.29 one such service in the area of academic resource discovery is google scholar’s updates, which analyzes a user’s publication history in order to predict new publications of interest.30 libraries, in contrast, have not pressed their developers and vendors to personalize their services in favor of privacy, even though studies have shown that users expect library tools to mimic their experience using web search engines.31 some web-scale discovery services do, however, allow researchers to set personalization preferences, such as their field of study, and, according to roger schonfeld, it is likely that many researchers would benefit tremendously from increased personalization in discovery.32 in this vein, the american philosophical society library recently launched a new recommendation tool for archives and manuscripts that uses circulation data and user-supplied interests to drive recommendations.33 opportunities for user experience in library discovery a major challenge in today’s online discovery environment is that the user is inhibited by an overwhelming number of results. this leads to users rely on relevance rankings and to fail to examine search results in depth. creating fine-tuned relevance ranking algorithms based on user behavior is one remedy to this problem, but it relies on the use of personal user data.34 however, there may be opportunities to facilitate data-driven discovery while maintaining the user’s anonymity that would be suitable for library (and other) discovery tools. irina trapido proposes that relevance ranking algorithms could be designed to leverage the popularity of a resource measured by its circulation statistics or by ranking popular or introductory materials higher than more specialized ones to help users make sense of large results sets.35 michael schofield proposes “context-driven design” as an intermediary solution, whereby the user opts in to have the system infer context from neutral device or browser information, such as the time of day, business hours, weather, events, holidays, etc.36 jason clark describes a search prototype he built that applies these principles, but he questions whether these types of enhancements actually add value to users.37 rachel vacek cautions that personalization is not guaranteed to be useful or meaningful, and continuous user testing is key.38 discussion there are several aspects to consider for the design of future library discovery tools. the integrated, complex nature of the web causes privacy to become compromised during the information discovery process. library discovery tools have been designed not to retain borrowing records, but have not yet evolved to mask user behavior, which is invaluable in today’s data economy. it is imperative that all types of library discovery tools have built-in functionality to privacy and user experience in 21st century library discovery | pekala https://doi.org/10.6017/ital.v36i2.9817 53 protect patron privacy beyond borrowing records, while also enabling the ethical use of patron data to improve user experience. even if library discovery tools were to evolve so that they themselves were absolutely private (where no data were ever collected or shared), other online parties (isps, web browsers, advertisers, data brokers, etc.) would still have access to user data through other means, such as cookies and fingerprinting. the operating reality is such that privacy is not immediately and completely controllable by libraries. laurie rinehart-thompson explains, “in the big picture, privacy is at the mercy of ethical and stewardship choices on the part of all information handlers.”39 while libraries alone cannot guarantee complete privacy for their patrons, they can and should mitigate privacy risks to the greatest extent possible. at the same time, ignoring altogether the benefits of using patron data to improve the discovery user experience may threaten the library’s viability in the age of google. roger schonfeld explains, “if systems exclude all personal data and use-related data, the resulting services will be onedimensional and sterile. i consider it essential for libraries to deliver dynamic and personalized services to remain viable in today's environment; expectations are set by sophisticated social networks and commercial destinations.”40 libraries must find ways to keep up with greater industry trends while adhering to professional ethics. recommendations while libraries have traditionally shied away from collecting data about patron transactions, these conservative tendencies run counter to the library’s mission to provide outstanding user experience and the need to evolve in a rapidly changing information industry. as the profession adopts new technologies, ethical dilemmas present themselves that are tied into their use. while several library organizations have issued guidance for libraries about the role of user data in these new technologies, this does not go far enough. the niso privacy principles, for instance, acknowledge that its principles are merely “a starting point.”41 examining the substance of these guidelines is important for confronting the privacy challenges facing library discovery in the 21st century, but there are additional steps libraries can take to more fully address the competing interests of privacy and user experience in library discovery and in library technologies more generally. holding third parties accountable libraries are increasingly at the mercy of third parties when it comes to the development and design of library discovery tools. unfortunately, these third parties not have the same ethical obligations to protect patron privacy that librarians do. in addition, the existing guidance for protecting user data in library technologies is directed towards librarians, not third party vendors. the library community must hold third parties accountable for the ethical design of library discovery tools. one strategy for doing this would be to develop a ranking or certification process for discovery tools based on a community set of standards. the development of hipaa-compliant information technology and libraries | june 2017 54 records management systems in the medical field sets an example. because healthcare providers are required by law to guarantee the privacy of patient data,42 they must select electronic health records systems (erms) that have been certified by an office of the national coordinator for health information technology (onc)-authorized body.43 in order to be certified, the system must adhere to a set of criteria adopted by the department of health and human services,44 which includes privacy and security standards.45 another example is the consumer reports standard and testing program for consumer privacy and security, which is currently in development. consumer reports explains the reason for developing this new privacy standard, “if consumer reports and other public-interest organizations create a reasonable standard and let people know which products do the best job of meeting it, consumer pressure and choices can change the marketplace.”46 libraries could potentially adapt the consumer reports standards and rating system for library discovery tools and other library technologies. engaging in ux research & design libraries should not rely on third parties alone to address privacy and user experience requirements for library discovery tools. libraries are well-poised to become more involved in the design process itself by actively engaging in user experience research and design. the opportunities for “context-driven design” and personalization based on circulation and other anonymous data are promising for library discovery but require ample user testing to determine their usefulness. understanding which types of personalization features offer the most value while preserving privacy is key to accelerating the design of library discovery tools. the growth of user experience librarian jobs and the emergence of user experience teams and departments in libraries signals an increasing amount of user experience expertise in the field, which can be leveraged to investigate these important questions for library discovery. illuminating the black box when librarians adopt new discovery tools without fully understanding their underlying technologies and the data economy in which they operate, this does not serve users. librarians have ethical obligations that should require them to thoroughly understand how and when user data is captured by library discovery tools and other web technologies, and how this information is compiled and shared at a higher level. not only do librarians need to understand the technical aspects of discovery technologies, they also need to understand the related user experience benefits and privacy concerns and the resulting ethical implications. as technology continues to evolve, librarians should be required to engage in continued learning in these areas. such technology literacy skills could be incorporated in the curriculum of library and information science degree programs, as well as in ongoing professional development opportunities. empowering library users because information discovery in an online environment introduces new privacy risks, communication about this topic between librarians and patrons is paramount. librarians should privacy and user experience in 21st century library discovery | pekala https://doi.org/10.6017/ital.v36i2.9817 55 proactively discuss with patrons the potential risks to their privacy when conducting research online, whether they are using the open web or library discovery tools. it is ultimately up to the patron to weigh their needs and preferences in order to decide which tools to use, but it is the librarian’s responsibility to empower patrons to be able to make these decisions in the first place. conclusion with the rollback of the fcc privacy rules that prohibit isps from selling customer search histories without customer permission, understanding digital privacy issues and taking action to protect patron privacy is more important than ever. while privacy and user experience are both necessary and important components of library discovery systems, their requirements are in direct conflict with each other. an absolutely private discovery experience would mean that no user data is ever collected during the search process, whereas a completely personalized discovery experience would mean that all user data is collected and utilized to inform the design and features of the system. it is essential for library discovery tools to have built-in functionality that protects patron privacy to the greatest extent possible and enables the ethical use of patron data to improve user experience. the library community must take action to address these requirements beyond establishing guidelines. holding third party providers to higher privacy standards is a starting point. in addition, librarians themselves need to engage in user experience research and design to discover and test the usefulness of possible intermediary solutions. librarians must also become more educated as a profession on digital privacy issues and their ethical implications in order to educate patrons about their fundamental rights to privacy and empower them to make decisions about which discovery tools to use. collectively, these strategies enable libraries to address user needs, uphold professional ethics, and drive the future of library discovery.

sandra shores is [tk] sandra shores editorial board thoughts: issue introduction to student essays t he papers in this special issue, although covering diverse topics, have in common their authorship by people currently or recently engaged in graduate library studies. it has been many years since i was a library science student—twenty-five in fact. i remember remarking to a future colleague at the time that i found the interview for my first professional job easy, not because the interviewers failed to ask challenging questions, but because i had just graduated. i was passionate about my chosen profession, and my mind was filled from my time at library school with big ideas and the latest theories, techniques, and knowledge of our discipline. while i could enthusiastically respond to anything the interviewers asked, my colleague remarked she had been in her job so long that she felt she had lost her sense of the big questions. the busyness of her daily work life drew her focus away from contemplation of our purpose, principles, and values as librarians. i now feel at a similar point in my career as this colleague did twenty-five years ago, and for that reason i have been delighted to work with these student authors to help see their papers through to publication. the six papers represent the strongest work from a wide selection that students submitted to the lita/ ex libris student writing award competition. this year’s winner is michael silver, who looks forward to graduating in the spring from the mlis program at the university of alberta. silver entered the program with a strong library technology foundation, having provided it services to a regional library system for about ten years. he notes that “the ‘accidental systems librarian’ position is probably the norm in many small and medium sized libraries. as a result, there are a number of practices that libraries should adopt from the it world that many library staff have never been exposed to.”1 his paper, which details the implementation of an open-source monitoring system to ensure the availability of library systems and services, is a fine example of the blending of best practices from two professions. indeed, many of us who work in it in libraries have a library background and still have a great deal to learn from it professionals. silver is contemplating a phd program or else a return to a library systems position when he graduates. either way, the profession will benefit from his thoughtful, well-researched, and useful contributions to our field. todd vandenbark’s paper on library web design for persons with disabilities follows, providing a highly practical but also very readable guide for webmasters and others. vandenbark graduated last spring with a masters degree from the school of library and information science at indiana university and is already working as a web services librarian at the eccles health sciences library at the university of utah. like mr. silver, he entered the program with a number of years’ work experience in the it field, and his paper reflects the depth of his technical knowledge. vandenbark notes, however, that he has found “the enthusiasm and collegiality among library technology professionals to be a welcome change from other employment experiences,” a gratifying comment for readers of this journal. ilana tolkoff tackles the challenging concept of global interoperability in cataloguing. she was fascinated that a single database, oclc, has holdings from libraries all over the world. this is also such a recent phenomenon that our current cataloging standards still do not accommodate such global participation. i was interested to see what librarians were doing to reconcile this variety of languages, scripts, cultures, and independently developed cataloging standards. tolkoff also graduated this past spring and is hoping to find a position within a music library. marijke visser addresses the overwhelming question of how to organize and expose internet resources, looking at tagging and the social web as a solution. coming from a teaching background, visser has long been interested in literacy and life-long learning. she is concerned about “the amount of information found only online and what it means when people are unable . . . to find the best resources, the best article, the right website that answers a question or solves a critical problem.” she is excited by “the potential for creativity made possible by technology” and by the way librarians incorporate “collaborative tools and interactive applications into library service.” visser looks forward to graduating in may. mary kurtz examines the use of the dublin core metadata schema within dspace institutional repositories. as a volunteer, she used dspace to archive historical photographs and was responsible for classifying them using dublin core. she enjoyed exploring how other institutions use the same tools and would love to delve further into digital archives, “how they’re used, how they’re organized, who uses them and why.” kurtz graduated in the summer and is looking for the right job for her interests and talents in a location that suits herself and her family. finally, lauren mandel wraps up the issue exploring the use of a geographic information system to understand how patrons use library spaces. mandel has been an enthusiastic patron of libraries since she was a small child visiting her local county and city public libraries. she is currently a doctoral candidate at florida state university and sees an academic future for herself. mandel expresses infectious optimism about technology in libraries: sandra shores (sandra.shores@ualberta.ca) is guest editor of this issue and operations manager, information technology services, university of alberta libraries, edmonton, alberta, canada. editorial board thoughts | shores 7 looking ahead, it seems clear that the pace of change in today’s environment will only continue to accelerate; thus the need for us to quickly form and dissolve key sponsorships and partnerships that will result in the successful fostering and implementation of new ideas, the currency of a vibrant profession. the next challenge is to realize that many of the key sponsorship and partnerships that need to be formed are not just with traditional organizations in this profession. tomorrow’s sponsorships and partnership will be with those organizations that will benefit from the expertise of libraries and their suppliers while in return helping to develop or provide the new funding opportunities and means and places for disseminating access to their expertise and resources. likely organizations would be those in the fields of education, publishing, content creation and management, and social and community webbased software. to summarize, we at ex libris believe in sponsorships and partnerships. we believe they’re important and should be used in advancing our profession and organizations. from long experience we also have learned there are right ways and wrong ways to implement these tools, and i’ve shared thoughts on how to make them work for all the parties involved. again, i thank marc for his receptiveness to this discussion and my even deeper appreciation for trying to address the issues. it’s serves as an excellent example of what i discussed above. people forget, but paper, the scroll, the codex, and later the book were all major technological leaps, not to mention the printing press and moveable type. . . . there is so much potential for using technology to equalize access to information, regardless of how much money you have, what language you speak, or where you live. big ideas, enthusiasm, and hope for the profession, in addition to practical technology-focused information await the reader. enjoy the issue, and congratulations to the winner and all the finalists! note 1. all quotations are taken with permission

growing “cloud” mark dehmlow information technology and libraries | march 2016 3 the library vendor market likes to throw around the word “cloud” to make their offerings seem innovative and significant. in many ways, much of what the library it market refers to as “cloud,” especially saas (software as a service) offerings, are really just a fancier term for hosted services. the real gravitas behind the label cloud really emanated from grid-computing or large interconnected, and quickly deployable infrastructure like amazon’s aws or microsoft’s azure platforms. infrastructure at that scale and that level of geographic distribution was revolutionary when it emerged. still these offerings at their core are basically iaas (infrastructure as a service) bundled as a menu of services. so i think the most broadly applicable synonym for the “cloud” could be “it as a service” in various forms. outsourcing in this way isn’t entirely new to libraries. the function and structure of oclc has arguably been one of the earlier instantiations of “it as a service” for libraries vis-à-vis their marc record aggregation and distribution which oclc has been doing for decades. the more recent trend toward hosted it services has been relatively easy for non-it related units in our library. a service no different to most library staff based on where it is hosted. and with many services implementing apis for libraries, that distinction is becoming less significant for our application developers too. for many of our technology staff, who have built careers around systems administration, application development, systems integration, and application management, hosted services represent a threat to not only their livelihoods but in some ways also their philosophical perspectives that are grounded in open source and do-ityourself oriented beliefs. in many ways the “cloud” for the it segment of our profession is perhaps more synonymous with change, and with change requires effective management of that change, especially for the human element of our organizations. recently, our office of information technologies started an initiative to move 80% of their technology infrastructure into the cloud. they have proposed an inverted pyramid structure for determining where it solutions should reside — focusing first on hosted software as a service solutions for the largest segment of applications, followed by hosting those applications we would have typically installed locally onto a platform or infrastructure as a service provider, and then limiting only those applications that have specialized technical or legal needs to reside on premise. this is a big shift for our it staff, especially, but not limited to, our systems administrators. the iaas platform our university is migrating to is amazon web services and their infrastructure is mark dehmlow (mdehmlow@nd.edu), a member of lita and the ital editorial board, is the director, information technology program, hesburgh libraries, university of notre dame, south bend, indiana. editorial board thoughts: the importance of staff change management in the face of the growing “cloud” | dehmlow | doi: 10.6017/ital.v35i1.8965 4 largely accessible via a web dashboard, so that the myriad of tasks our systems administrators took days and weeks to do can now, in some adjusted way, be accomplished with a few clicks. this example is on one extreme end of the spectrum as far as it change goes, but simultaneously, we have looked at the vendor market to lease pre-packaged tools that support standard functions in academic libraries and can be locally branded and configured with our data — things like course guides, a-z journal lists, scheduling events, etc. the overarching goals of these efforts are cost savings and increased velocity and resiliency of infrastructure, but also and perhaps more important, is giving us flexibility in how we invest our staff time. if we are able to move high level tasks from staff to a platform, then we will be able to reallocate our staff’s time and considerable talent to take on the constant stream of new, high level technology needs. partnering with the university, we are aiming towards their defined goal of moving 80% of our technical infrastructure into the “cloud.” we have adopted their overall strategy of approach to systems infrastructure, at least in principle and are integrating into our own strategy significant consideration for the impact of these changes on our staff. our organization has recognized that people form not only habits around process, but also personal and emotional attachments to why we do things the way we do them, both from a philosophical as well as a pragmatic perspective. our approach to staff change is layered as well as long term. we know that getting from shock to acceptance is not an overnight process and that staff who adopt our overarching goals and strategy as their own will be more successful in the long term. to make this transition, we have developed several strategic approaches: 1. explaining the case: my experience is that staff can live through most changes as long as they understand why. helping them gain that understanding can take some time, but ultimately having that comprehension will help them fully understand our strategic goals as well as help them make decisions that are in alignment with the overall approach. i often find it is important to remember that, as managers, we have been a part of all of the change conversations and we have had time to assimilate ideas, discuss points of view, and process the implications of change. each of our staff needs to go through the same process and it is up to leadership to guide them through that process and ensure they get to participate in similar conversations. it is tempting to want to hit an initiative running, but there is significant value in seeding those discussions gradually over a somewhat gradual time period to more holistically integrate staff into the broader vision. it is important to explain the case for change multiple times and actively listen to staff thoughts and concerns and to remember to lay out the context for change, why it is important, and how we intend to accomplish things. then reassure, reassure, and reassure. the threats to staff may seem innocuous or unfounded to managers, but staff need to feel secure during a process to ultimately buy in. 2. consistency and persistence: staff acceptance doesn’t always come easy — nor should it necessarily. listening and integrating their perspectives into the planning and information technology and libraries | march 2016 5 implementation process can help demonstrate that they matter, but equally important is that they feel our approach is built on something solid. stability is reinforced through consistency in messaging. not only in individual consistency, but also team consistency, and upper management consistency — everyone should be able to support and explain messaging around a particular change. any time staff approach me and say, “it was much easier to do it this other way,” i talk about the efficiency we will garner through this change and how we will be able to train and repurpose staff in the future. the more they hear the message, the more ingrained it becomes, and the more normative it begins to feel. 3. training and investment: it futures require investment, not just in infrastructure, but also in skill development. we continue to invest significantly in providing some level of training on new technologies that we implement. that training will not only prove to staff that you are invested in their development as well as their job security, but it will also give them the tools they need to be successful in implementing new technologies. change is anxiety inducing because it exposes so many unknowns. providing training helps build confidence and competence for staff, reducing anxieties and providing some added engagement in the process. it also gives them exposure to the real world implementation of technologies where they can begin to see the benefits that you have been communicating for themselves. 4. envisioning the future: improvements and roles — one of the initial benefits we will be getting from recouping staff time is around shoring up our processes. we have generally had a more ad hoc approach to managing the day to day. it has been difficult to institute a strong technical change management process, in part, because of time. we will be able to remove that consideration from our excuses as we take advantage of the “cloud.” the net effect will be that we will do our work more thoughtfully and less ad hoc and use better defined processes that will meet group-developed expectations. in addition to doing things better, we do expect to do things differently. with fewer tasks at the operational level, we believe we will be able to transition staff into newly defined roles. some of these roles include devops engineers, a hybrid of application engineering (the dev) and systems administration (the ops), these staff will help design automation and continuous integration processes that allow developers to focus on their programming and less on the environment they are deploying their applications in; financial engineers who will take system requirements and calculate costs in somewhat complex technical cloud environments; systems architects who will be focused on understanding the smorgasbord of options that can be tied together to provide a service to meet expected response performance, disaster recovery, uptime, and other requirements; and business analysts who will focus on taking technical requirements and looking at all of the potential approaches to solve that need whether it be a hosted service, a locally developed solution, an implementation of an open source system, or some integration of all or some of the editorial board thoughts: the importance of staff change management in the face of the growing “cloud” | dehmlow | doi: 10.6017/ital.v35i1.8965 6 above. this list is by no means exhaustive, but i think it forms a good foundation on which to help staff develop their skill set along with our changing environment. i believe it is important to remind those of us who are managing it departments in libraries that in many ways the easiest parts of change are the logistics. the technology we work with is bounded by sets of guidelines that define how they are used and ensure that if they are implemented properly, they will work effectively. people on the other hand are not bounded as neatly by stringent rules. they are guided by diverse backgrounds, personalities, experiences, and feelings. they can be unpredictable, difficult to fully figure out, and behaviorally inconsistent. and yet, they are the great constant in our organizations and therefore require significant attention. our field needs “servant leaders” dedicated to supporting and developing staff, and not just being competent at implementing technologies. those managers who invest in staff, their well-being, development, and sense of engagement in their jobs, will find their organizations are able to tackle most anything. but those who ignore their staffs’ needs over pragmatic goals will likely find their organizations struggling to move quickly and instead spend too much energy overcoming resistance instead of energizing change. reproduced with permission of the copyright owner.

1; proquest pg. 42 l site license initiatives in the united kingdom: the psli and nesli experience jacqueline borin this article examines the development of site licensing within the united kingdom higher education community. in particular, it looks at haw the pressure to make better use of dwindling fiscal resources led ta the conclusion that information technology and its exploitation was necessary in order to create an effective library service. these conclusions, reached in the follett report of 1993, led to the establishment of a pilot site license initiative and then a national electronic site license initiative. the focus of this article is these initiatives and the issues they faced, which included off-site access, definition of a site and perhaps most importantly, the unbundling of print and electronic journals. increased competition for institution funding around the world has resulted in an erosion of library funding. in the united states state universities are receiving a decreasing portion of their funds from the state while private universities are forced to limit tuition increases due to outside market forces. in the united kingdom the entitlement to free higher education is currently under attack and losing ground. today's economic pressures are requiring individual libraries to make better use of their fiscal resources while the emphasis moves from being a repository for information to providing access to information. jacqueline sorin (jborin@csusm.edu) is coordinator of reference and electronic resources, library and information services, california state university, san marcos. as in the united states, the use of consortia for cost sharing in the united kingdom is becoming imperative as producers produce more electronic materials and make them available in full-text formats. consortia, while originally formed to cooperate on interlibrary loans and union catalogs, have recently taken on a new role, driven by financial expediency, in negotiating electronic licenses for their members, and the percentage of vendor contracts with consortia are rising. academic libraries cannot afford the prevalent pricing model that asks for the current print price plus an electronic surcharge plus projected inflation surcharges, therefore group purchasing power allows higher education institutions to leverage the money they have and to provide resources that would otherwise be unavailable. advantages for the vendor include one negotiator and one technical person for the consortia as a whole. in addition, the use of consortia provide greater leverage in pushing for the need for stable archiving and for retaining the principles of fair use within the electronic environment as well as reminding publishers of the need for flexible and multiple economic models to deal with the diverse needs and funding structures of consortia. i during the spring of 1998, while visiting academic libraries in the united kingdom, i looked at an existing initiative within the uk higher education community-the pilot site license initiative (psli), which had begun as a response to the follett report and to rising journal prices. at the time the three-year initiative was nearing its end and its successor, the national electronic site license initiative (nesli), was already the topic of much discussion. i history the concept of site licensing in the united kingdom higher education 42 information technology and libraries i march 2000 community had already been established, since 1988, by the combined higher education software team (chest), based at the university of bath. chest has negotiated site licenses with software suppliers and some large database producers through two different methods. either the supplier sells a national license to chest, which passes it on to the individual institution or chest sells licenses to the institution on the suppliers behalf and passes the fees on to them (see figure 1). chest works closely with national information services and systems (niss). niss provides a focal point for the uk education and research communities to access information resources. niss's web service, the niss information gateway, provides a host for chest information such as ebsco masterfile and oclc netfirst. most chest agreements are institution-wide site licenses that allow for all noncommercial use of the product, normally for five years to allow for incorporation into the curriculum. once an institution signs up it is committed for the full term of the agreement. chest is not in the business of either evaluating products or differentiating among competing suppliers. evaluations and purchase decisions are left up to the individual institutions.2 chest does set up and support e-mail discussion lists for each agreement so that users can discuss features and problems of the product among themselves. they also send out electronic news bulletins to provide advance warning of forthcoming agreements and to assess level of interest in future agreements. chest operates in a similar manner to many library consortia in the united states. the major differences are that it sells to higher education institutions as a whole so the products they sell include not only databases but also for example, software programs. this is also beginning to change in reproduced with permission of the copyright owner. further reproduction prohibited without permission. the united states. a recent article in the chronicle of higher education mentions that institutions will not stop with library databases, "in the future we'll be negotiating site licenses for software and all sorts of things . . . not just databases."3 although chest is substantially self-funding it is strongly supported (as is niss) by the joint information systems committee (jisc) of the higher education funding councils of england (hefce). the majority of public funding for higher education funding in the united kingdom is funneled through the hefcs (one each for england, scotland, wales, and northern ireland). one of the jisc committees, the information services subcommittee (issc), which in 1997 became part of the committee for electronic information (cei) defined principles for the delivery of content. 4 they were: • free at the point of use; • subscriptions not transaction based; • lowest common denominator; • universality; • commonality of interfaces and • mass instruction. i follett report in 1993 an investigation into how to deal with the pressures on library resources caused by the rapid expansion of student numbers and the worldwide explosion in academic knowledge and information was undertaken by the joint funding council 's libraries review group, chaired by sir brian follett. this investigation resulted in the follett report. one of the key conclusions of the report was "the exploitation of it is essential to create the effective higher education and public research establishments software, data , training needs ! chest © chest (university of bath) 1996 figure 1. chest diagram chest deals , chest offers negotiations software , data, training materials t it product suppliers library service of the future ." the review group recommended that as a starting point "a pilot initiative between a small number of institutions and a similar number of publishing houses should be sponsored by the funding councils to demonstrate in practical terms how material can be handled and distributed electronically." 5 as a consequence £15 million was allocated to an electronic libraries program, managed by jisc on behalf of hefce. the electronic libraries program was to "engage the higher education community in developing and shaping th e implementation of the electronic library." 6 this project provided a body of electronic resources and services for uk higher education and influenced a cultural shift towards the acceptance and use of electronic resources instead of more traditional information storage and access methods. psli in may 1995 a pilot site license initiative subsidized by the funding councils was set up to : • test if the site license concept could provide wider access to journals for those in the academic community; • see if it would allow more flexibility in the use of scholarly material ; • test the methods for dissemination of scholarly material to the higher education sector in a variety of formats ; • test legal models for a national site license program; and • explore the possibility for increased value for money from scholarly journals.7 sixty-five publishers were invited by hefce to participate for three years commencing january 1, 1996. hefce was also responsible through jisc for the funding of the elib program, but no formal links were established between the elib project and communications i borin 43 reproduced with permission of the copyright owner. further reproduction prohibited without permission. the psli. 8 the final selection of four companies included academic press ltd., blackwell publishers ltd., blackwell science ltd., and iop publishing ltd. the publishers agreed to offer print journals to higher education institutions for discounts of between 30 and 40 percent over the three year period as well as electronic access as available. originally the electronic journals were supposed to be the subsidiary component of the agreement but by the end of the agreement they had become the major focus. the psli achieved almost 100 percent take up among the higher education institutions due to the anticipated savings through the program.9 hefce did not specify how the publishers were to deliver their content. iopp hosted the journals on their own server, for example, while academic press linked their ideal server to the journals online service at the university of bath. one of the key provisions of the site license was the unlimited rights of authorized users to make photocopies (including their use within course packs) of the journals. academic press and iopp provided full-text access to all their journals while blackwell and blackwell science only allowed reading of full text where a print subscription existed. an integral part of the psli was that the funding from hefce to the higher education institutions was top sliced to support the discounted price offered to the institutions. several assessments of the initiative were made and a final evaluation of the pilot was concluded at the end of 1997. initial surveys indicated subscription savings through the program (average annual savings were approximately £11,800 per annum) and the first report of the evaluation team showed a wide level of support for the project despite major problems with lack of communication in a timely manner.10 the team recommended an extension of the psli to include more publishers and more emphasis on electronic delivery. one concern that was raised was ease of access, students had to know which system a journal they required was on. this was not easily discernible or user friendly. evaluations by focus groups showed users wanted one single access point to all electronic journals.11 also unresolved was the need for one consistent interface to the electronic journals and a solution to the archiving issue. at the end of the psli, hefce handed the next phase over to jisc. in the fall of 1997 jisc announced that a nesli would be set up and a new steering group was established. nesli was to be an electronic-only scheme and the invitation to tender went out at the end of 1997 with a decision to be made mid-1998. national electronic site license initiative nesli, a three-year jisc funded program, began on january 1, 1999 although the "official" launch was held at the british library on june 15, 1999. it is an initiative to deliver a national electronic journal service to the united kingdom higher education and research community (approximately 180 institutions) and is a successor program to the pilot site license initiative {psli). in may 1998 jisc appointed a consortium of swets and zeitlinger and manchester computing {university of manchester) to act as a managing agent (swets and blackwell ltd. announced in june 1999 their intention to combine swets subscription service and blackwell's information services, the two subscription agency services). the managing agent represents the higher education institutions in negotiations with publishers, manages delivery of the electronic material through a single web interface and oversees day-to-day operation of the program including the handling of subscriptions.12 44 information technology and libraries i march 2000 the managing agent also encourages the widespread acceptance by publishers of a standard model site license, one of the objectives of this being to reduce the number and diversity of site definitions used by publishers. other important provisions of the model site license addressed the issues of walk-in use by clients and the need for publishers to provide access to material previously subscribed to when a subscription is cancelled. the subscription model is currently the prevalent option although they are also working towards a pay-per-view option.13 priority has been given to publishers who had been involved in the psli and to those publishers participating in swetsnet, the delivery mechanism for the nesli. swetsnet is an electronic journal aggregation service that offers access to and management of internet journals. its search engine allows searching and browsing through titles from all publishers with links to the full-text articles. nesli is not a mandatory initiative, the higher education institutions can choose whether to participate in proposals and can pursue their own arrangements individually or through their own consortiums if they wish. while psli was basically a printbased initiative limited to a small number of publishers and funded via top slicing, nesli is an electronic initiative aimed at involving many more publishers. it is designed to be self-funding, although it did receive some start-up funding. although it is an electronic initiative, proposals that include print will be considered, as it is still not easy to separate print and electronic materials.14 the initiative addresses the most effective use, access, and purchase of electronic journals in the academic library community. its aims include: • access control-for on-site and remote users; • cost; reproduced with permission of the copyright owner. further reproduction prohibited without permission. • definition of a site; • archiving; and • unbundling print from electronic. access to swetsnet, the delivery mechanism for journals included in nesli, has now been supplemented by the option of athens authentication. athens, an authentication system developed by niss, provides individuals affiliated with higher education institutions a single username and password for all electronic services they have permission to access. athens is linked to swetsnet to ensure access for off-site, remote, and distance learners who do not have a fixed ip address. this supplements swetsnet's ip address authentication, which does not allow for individual access to toc and sdi alerting. a help desk is available for all nesli users through the university of manchester. the definition of a site is being addressed by the nesli model site license, which tries to standardize site definitions (including access from places that authorized users work or study, including homes and residence halls); interlibrary loan (supplying an authorized user of another library a single paper copy of an electronic original of a individual document); walk-in-users; access to subscribed material in perpetuity (it provides for an archive to be made of the licensed material with access to the archive permissible after termination of the license); and inclusion of material in course packs. jisc' s nesli steering group approved the model nesli site license on may 11, 1999 for use by the nesli managing agent.15 the managing agent asks publishers to accept the model license with as few alterations as possible. during the term of the initiative the managing agent will be working on additional value added services. these include links from key indexing and abstracting services, provision of access via z39.50, linking from library opacs, creation of catalog records and assessing a model for ejournal delivery via subject clusters. in particular, they have begun to look at the technical issues concerned with providing marc records for all electronic journals included in nesli offers. additionally they will be looking at solutions for longer term archiving of electronic journals to provide a comfort level for librarians purchasing electronic only copies.16 two offers that have been made under the nesli umbrella so far are blackwell sciences for 130 electronic journals and johns hopkins university press for 46 electronic titles. most recently two additional vendors have been added to the list. elsevier has made a proposal to deliver full text content via the publishers sciencedirect platform that includes the full text of more than 1,000 elsevier science journals along with those of other publishers. a total of more than 3,800 journals would be included in the service.17 mcb university press, an independent niche publisher, is offering access to 114 full text journals and secondary information in the area of management through it's emerald intelligence + fulltext service. similarly, here in the united states, california state university (csu) put out for competitive tender a contract for the building of a customized database of 1200+ electronic journals based on the print titles subscribed to by 15 or more of the 22 campuses-journal access core collection oacc). the journals will be made available via pharos, a new unified information access system for the csu. like ohiolink, a consortium of 74 ohio libraries, it will provide a common interface to electronic journals for students and faculty and will facilitate the development of distance learning programs.18 by unbundling the journals, libraries will no longer be required to pay for journals they do not want or need leading to moderate price savings. additional savings can be realized through the lowering of overhead costs achieved by system wide purchasing of core resources. other issues being addressed within the jacc rfp included archiving and perpetual access to journal articles the university system has paid for, availability of e-journals in multiple formats, interlibrary loan of electronic documents, currency of content and cost value at the journal-title level. 19 currently 500 core journals are being provided under the jacc by ebsco information services and the csu plans on expanding those offerings. i conclusion as we move into the next millennium library consortia will continue to work together with vendors to further customize journal offerings. however it is still far too early to say whether nesli will be successful or whether it will succeed in getting the publishing industry to accept the model site license. if it is to work within the higher education community, it will depend greatly on the flexibility and willingness of the publishers of scholarly journals. it has made a start by developing a license that sets a wider definition of a site and that deals realistically with the question of off-site access. by encouraging the unbundling of electronic and print subscriptions nesli allows services to be tailored to specific needs of the information community, but it remains to be seen how many publishers are prepared to accept unbundled deals at this stage. also as technology stabilizes and libraries acquire increasingly larger electronic collections, we will not be able to rely on license negotiations as the only way to influence pricing, access, and distribution. an additional problem that remains unaddressed by either psli or nesli is the pressure on academics to publish in traditional journals and the corcommunications i borin 45 reproduced with permission of the copyright owner. further reproduction prohibited without permission. responding rise in scholarly journal prices. nesli neither encourages nor hinders changes in scholarly communication and therefore the question of restructuring the scholarly communication process remains.20 references and notes 1. barbara mcfadden and arnold hirshon, "hanging together to avoid hanging separately: opportunities for academic libraries and consortia,"

about the use of java applets to publish small directories and bibliographies.2 sturr has discussed the use of wais software to provide searchable online indexes.3 many of the web-based local databases and search interfaces currently used by libraries may: • have problems with functionality; • lack provisions for efficient searching; • be based on unreliable software; • be based on

retrieval efficiency dirk w. fokker and michael f. lynch: postgraduate school of librarianship and information science, university of sheffield, england. keys consisting of variable-length chamcter strings from the front and rear of surnames, derived by analysis of author names in a particular data base, am used to provide approximate representations of author names. when combined in appropriate mtios, and used together with keys for each of the first two initials of personal names, they provide a high degme of discrimination in search. methods for optimization of key-sets are desc1·ibed, and the performance of key-sets varying in size between 150 and 300 is determined at file sizes of up to 50,000 name entries. the effects of varying the proportions of the queries present in the file are also examined. the results obtained with fixed-length keys are compared with those f01' variable-length keys, showing the latter to be greatly superior. implications of the work for a variety of types of information systems a1'e discussed. introduction in part i of this series the development of variety generators, or sets of variable-length keys with high relative entropies of occurrence, from the initial and terminal character strings of authors' surnames was described.1 their purpose, used singly or in combination, is to provide a high and constant degree of discrimination among personal names so as to facilitate searches for them. in this paper the selection of optimal combinations of the keys and evaluation of their efficiency in search are described. the performance of combined key-sets of various compositions is determined at a range of file sizes and compared with fixed-length keys. in addition, 202 1 ournal of lib1'm'y automation vol. 7 i 3 september 197 4 the extent of statistical associations among keys from different positions in the names is determined. balancing of key-sets the relative entropies of distribution of the first and last letters of the surnames of authors in the file of 100,000 entries from the inspec data base differ significantly, the former being 0.92 and the latter 0.86. as a result, a larger key-set has to be produced from the back of the surnames to reach the same value of the relative entropy as that of a key-set of given size from the front of the surname. for instance, the value of 0.954 is reached by a key-set comprising 41 keys from the front of the name, but a set of 101 keys from the back is needed to attain this value. it seemed reasonable to assume that keys from the front and rear should be combined in different proportions in order to maximize the relative entropy of the combined system, and that their proportions should reflect the redundancies of each distribution (redundancy = 1 hr). in order to test this, a series of combined key-sets of different total sizes was produced, in which the proportions of keys were varied around the ratio of the redundancies of the first and last character positions, i.e., ( 1 0.92): ( 1 0.86), or 8:14. the relative entropies of the name representations provided by combining these key-sets with keys for the first and second initials were determined by applying them to the 50,000 name file, and the entropy value used to determine the optimal ratio of keys. in one case, the correlation between the value of the relative entropy and retrieval efficiency, as measured by the precision ratio, was also studied, and shown to be high. the sizes of the combined key-sets studied were 148 and 296, with an intermediate set of 254 keys. the values of 148 and 296 were chosen in view of the projected implementation in the serial-parallel file organization.2 this relates the size of the key-set to the number of blocks on one cylinder of a disc. (the 30mbyte disc cartridges available to us have 296 blocks per cylinder.) otherwise the choice of key-set is arbitrary, and can be varied at will. the minimum key-set size is 106, consisting of 26 letters each for the first and last letter of the surname, and 27 ( 26 letters and the space symbol) each for the first and second initials. the numbers of n-gram keys ( n ::::,. 2) required for the key-sets numbering 148, 254, and 296 in size are . thus 42, 148, and 190. full details are given of the composition of the first and third of these sets. a slight refinement to key-set generation was employed to ensure as close an approximation to equifrequency as possible, especially with the smallest key-sets. precise application of a threshold frequency may occasionally result in arbitrary inclusion of either very high or very low frequency keys. thus, if almost all the occurrences of a longer key are accounted for by a shorter key (as with -mann and -ann), only the shorter n-gram is included. va1'iety-generato1· approach/fokker and lynch 203 optimal set of 148 keys the number of n-gram keys ( n ::::::,. 2) to be added to the minimum set of 106 keys is 42, the presumed optimum proportion being 8:14, which implies about 16 keys from the front of the name and 26 from the back. in order to examine the relationship between the ratio of keys from the front and rear of the surname and the relative entropy of the combined sets, the ratios were varied at intervals between 1:1 and 1:3 so that the numbers of n-grams varied from 21 and 21 to 11 and 31 respectively. for each ratio the keys were applied to the 50,000 name entries, and the distribution of the resultant descriptions determined. the ratios, the number of n-gram keys, and the relative entropies of the distributions are shown in table 1. the maximum value of the entropy is taken to be log250,000. in this case the balancing point, with the key-set including 16 n-gram keys table 1. relation between ratio of n-grams f1'0m f1'dnt and rear of surname, entropy of combined key-sets, and retrieval efficiency for a series of sets of 148 keys ratio numbm· of n-gram number of diffm·ent relative · precision(%) of n-gram keys representations entropy (file size= keys front back in 50,000 entries of system 25,000) 1:1 21 21 33,485 0.9450 71.5 3:4 18 24 33,501 0.9450 71.3 17:25 17 25 33,434 0.9447 70.9 8:13 16 26'* 33,454 0.9453 72.2 5:9 15 27 33,402 0.9450 72.0 1:2 14 28 33,378 0.9449 72.1. 1:3 11 31 33,126 0.9437 71.5 total number of different name entries = 41,469.

of 296 keys a similar procedure to that used for the optimal148-key key-set was also applied in this instance. here the ratios of front and rear n-gram keys varied from 57 and 133 to 69 and 121 respectively. for each of the sets chosen, the distributions of the entries resulting from application of the combined key-sets to the file of 50,000 names were determined. these showed virtually no difference in terms of the relative entropy alone, although the total number of different entries differed slightly between keysets, and the highest value was used to choose the optimal set, detailed in table 4. the range of combinations studied is shown in table 5, and the distribution of the entries for the optimal set is given in table 6. .. , -::: 204 journal of library automation vol. 7/3

eliminated in a subsequent character-by-character match of the candidate hits, the proportion of unwanted items should remain low if the method is to offer advantages. in evaluating the effectiveness of the key-sets in the retrieval, the names in the search file were represented by concatenating the codes for the keys from the front and back of the surnames and the initials, and subjecting the query names to the same procedure. the matching procedure produced lists of candidate entries, of which the desired entries were a subset. the final determination was carried out manually. the tests were performed first with names sampled from the search file, so that correct items were retrieved for each query. since searches for name entries may be performed with varying probabilities that the authors' names are present in the file (especially in current-awareness searches), varying proportions of names of the same provenance, but known not to be present in the search file, were also added. in these cases candidate items were selected which included none of the desired entries. recall tests were also performed and recall shown to be complete. the measure used in determining the performance of the variety-generator search method is the precision ratio, defined as the ratio of correctly identified names to all names retrieved. it is presented both as the ratio of averages (i.e., the summation of items retrieved in the search and calculation of the average) and as the average of ratios (i.e., averaging the val'iety-genemtor app1'0ach/fokker and lynch 207 figures for individual searches). the latter gives higher figures, since many of the individual searches give 100 percent precision ratios. the precision ratio was found to be dependent on file size and to fall somewhat as the size of file increases. this is due to the fact that the keysets provided only a limited, if very high, total number of possible combinations, while the total possible variety of personal names is virtually unlimited. the evaluation was performed with a sample of 700 names, selected by interval sampling. this number ensured a 99 percent confidence limit in the results. a comparison of the interval sampled query names with randomly sampled names showed that no bias was introduced by interval sampling. a test to confirm that the retrieval effectiveness reached a peak at the maximum value of the relative entropy of a balanced key-set was performed first. this was carried out on a file of 25,000 names, using as queries names selected from the file and the optimal 148-key key-set. as shown in table 1, the values of the precision ratio (ratio of averages) and of the relative entropy both peak at the same ratio of n-gram keys from the front and back of the surnames. the performance of the optimal key-sets of 148, 254, and 296 keys with files of 10,000, 25,000, and 50,000 names is shown in table 7. calculated as the ratio of averages, the smallest key-set ( 148 keys) shows a precision ratio of 64 percent with a file of 50,000 names, which means that of every three names identified in the variety-generator search, two are those desired. with the largest key-set ( 296 keys), this rises to nine correctly identified names in every ten retrieved at this stage. on the other hand, calculated as the average of ratios, the precision ratios rise to 81 percent and 94 percent respectively. for smaller file sizes-typical, for instance, of current-awareness searches-the figures for all of these are cottespondingly higher. table 7. precision ratios

file of 25,000 names. in this case, the proportion of correctly identified names in the total falls, so that overall performance is somewhat reduced. thus, depending both on file size and on the expected proportion of queries identifying hits, the key-set size can be adjusted to reach a desired level of performance. in addition, tests to determine the table b. effect of varying proportion of

size were carried out. the three key-sets derived from the first file were applied to the second, query names sampled from the latter, and the precision ratios determined. some reduction in performance was observed; expressed as ratio of averages, the precision with the 296-key key-set fell from 90 to 83 percent, with the 254-key keyset from 87 to 82 percent, and with the 148-key key-set from 64 to 56 percent, figures which seem unlikely to prejudice the net performance in any marked way. nonetheless, monitoring of performance and of data base name characteristics over a period of operation might well be advisable. distribution characteristics of other types of keys it is particularly instructive to examine the distribution characteristics of other types of keys, including those of fixed length, generated from various positions in the names, and to compare them with those of the optimal key-sets employed in the variety-generator approach. to this end, the file of 50,000 names was processed to produce the following keys or keysets: 1. initial digram of surname. 2. initial trigram of surname. 3. key-set of ninety-four n-grams from the front of the surname, with first and second initials. 4. key-set consisting of first and last character of surname, with first and second initials. the figures (table 9) show clearly that all have distributions which leave no doubt as to their relative inadequacy in resolving power, where this is defined as the ratio of distinct name representations provided by the key-set used to the number of different name entries ( 41,469) in the file. at the digram level, the value of the resolving power is 0.009, i.e., each vm·iety-generator approach/fokker and lynch 209 digram represents, on average, 110 different name entries, while no fewer than thirty-two specific digrams each represent between 500 and 1,000 different names. at the trigram level, the value of the resolving power rises to 0.08, a tenfold increase; however, one trigram still represents between 500 and 1,000 different names. use of the first and last letters of the surname plus the initials again increases the value of the resolving power to 0.627, or 1.6 distinct names per entry; eight of the representations now account for between thirty-one table 9. distributions of a variety of other representations of personal names in a file of 50,000 entries 94

first and second initials, although almost 50 percent larger than the fourcharacter representation, has a resolving power of only 0.438 (or 2.28 entries per representation). this contrast provides particularly strong evidence for the superiority of keys from the front and rear of the surnames over those from the front alone, even when the latter are variable in •' 210 journal of library automation vol. 7/3 september 1974 length. as expected, the precision ratio of the four-character representation is low, at 37 percent (ratio of averages), compared with 64 percent for the optimal148-key key-set. extent of statistical association among keys thus far, the frequency of occurrence of variable-length character strings from the front and back of the surnames is the only factor considered in their selection as keys. it is well known in other areas that statistical associations among keys can influence the effectiveness of their combinations. 3 where a strong positive association between two keys exists, their intersection results in only a small reduction of the number of items retrieved over that obtained by using each independently. when the association is strongly negative, the result of intersection may be much greater than that predicted on the basis of the product of the individual probabilities of the keys. to assess the extent of associations among keys from the front and rear of surnames and initials, sets of both fixedand variable-length keys from each of these positions were examined.· the kendall correlation coefficient v was calculated for each of the twenty most frequent combinations of these. this is related to the chi-square value by the expression x2 =m v2 where m is the file size, or 50,000. table 10 shows the values of the association coefficient for certain of the characters in the full name. those above .012 are significant at a 99 percent confidence level. positive associations are table 10. a8sociation

association coefficients among the twenty most frequent combinations of keys from the front and back of surnames in the 148and 296-key key-sets show magnitudes (mostly positive) which are substantially greater than those for single characters (see table 11). the reasons for these values are obvious; in certain instances, e.g., miller, jones, and martin, common complete names are apparent, while in one case, lee, an overlap between keys from the front and rear exists. in others, linguistic variations on common names can be discerned, as with br n-brown or braun. table 11.

associations are inevitable. when the selection of keys is based solely on frequency, some deviation from the ideal of independence must result, becoming larger as the size of the key-sets increases, and as the length of certain of the keys increases. however, since its effect in the most extreme cases is merely to lead to virtually exact definition of the most frequent surnames, no particular disadvantage results. possible implementations of the variety-generator name search approach the variety-generator approach permits a number of possible implementations of searches for personal names to be considered, if only in outline f ( f•j/ 212 journal of library automation vol. 7/3 september 1974 at this stage, using a variety of file organization methods. the most widely known methods (apart from purely sequential files) are direct access (utilizing hash-addressing), chained, and index sequential files. direct application of the concatenated key-numbers as the basis for hash-address computation appears attractive in instances where the personal name is used alone or in combination (as, for instance, with a part of the document title). the almost random distribution of the bits in this code should result in a general diminution of the collision and overflow problems commonly encountered with fixed-length keys. since only four keys are used to represent each name, and the four sets of keys from which these are selected are limited in number and of approximately equal probability, the keys can be used to construct chained indexes, to which, however, the usual constraints still apply. index sequential storage again offers opportunities, in particular since the low variety of key types means that the sorting operations which this entails can be eliminated. in effect, each name entry would be represented by an entry in each of four lists of document numbers or addresses, and documents retrieved by intersection of the lists. while four such numbers are stored for each name, in contrast to a single entry for the more conventional name list, the removal of the name list itself would more than compensate for the additional storage required for the lists. in the index sequential mode, the lists of document addresses or numbers stored with each key are more or less equally long. they may thus be replaced by bit-vectors in which the position of a bit corresponds to a name or document number. if the number of keys bears a simple relation to the number of blocks on a disc cylinder, the vectors can be stored in predetermined positions within a cylinder, resulting in the serial-parallel file. the usefulness of this file organization has yet to be fully evaluated; however, it also promises substantial economies in storage. on average, only four of the bits are set at the positions in the vectors corresponding to the name or document entry. on average, then, the density of 1-bits is very low, and long runs of zeros occur in the vectors. they can, therefore, be compressed using run-length coding, for instance as applied by bradley.3· 4 preliminary work with the 296-key key-set has indicated already that a gross compression ratio of nine to one is attainable, so that the explicit storage requirements to identify the association between a name and a document number would be just over thirty bits. conclusions the work described here relates solely to searches for individual occurrences of personal names. clearly, in operational systems in which one or more author names are associated with a particular bibliographical item, it will be necessary to provide for description of each of these for access. if this is provided solely on the basis of a document number, some false coordination will occur-for instance, when the initials of one entry are variety-generator approach/fokker and lynch 213 combined with the surname of another. a number of strategies can be envisaged to overcome this problem. , the performance figures show clearly that a small number of characteristics-between 100 and 300 in this study-are sufficient to characterize the entries in large files of personal names and to provide a high degree of resolution in searches for them. while performance in much larger files, involving the extension of key-set sizes to larger munbers, has yet to be studied, the logical application of the concept of variety generation would appear to open the way to novel approaches to searches for documents associated with particular personal names, which seem likely to offer advantages in terms of the overall economic performance of search systems, not only in bibliographic but also in more general computer-based information systems. acknowledgments we thank m. d. martin of the institution of electrical

yang information technology and libraries | june 2014 5 abstract selection and implementation of a web-scale discovery tool by the rider university libraries (rul) in the 2011–2012 academic year revealed that the endeavor was a complex one. research into the state of adoption of web-scale discovery tools in north america and the evolution of product effectiveness provided a good starting point. in the following study, we evaluated fourteen major discovery tools (three open source and ten proprietary), benchmarking sixteen criteria recognized as the advanced features of a “next generation catalog.” some of the features have been used in previous research on discovery tools. the purpose of the study was to evaluate and compare all the major discovery tools , and the findings serve to update librarians on the latest developments and user interfaces and to assist them in their adoption of a discovery tool. introduction in 2004, the rider university libraries’ (rul) strategic planning process uncovered a need to investigate federated searching as a means to support rese arch. a tool was needed to search and access all journal titles available to rul users at that time, including 12,000+ electronic full-text journals. lacking the ability to provide relevancy ranking due to its real-time search operations, as well as the cost of the products then available, the decision was made to defer implementation of federated search. monitoring developments yearly revealed no improvements strong enough to adopt the approach. by 2011, the number of electronic full-text journals had increased to 51,128, and by this time federated search as a concept had metamorphosed into web -scale discovery. clearly, the time had come to consider implementing this more advanced approach to searching the ever-growing number of journals available to our clients. though rul passed on federated searching, viewing it as too cumbersome to serve our students well, we anticipated the day when improved systems would emerge. vaughn nicely describes the ability of more highly evolved discovery systems to “provide qu ick and seamless discovery, delivery, and relevancy-ranking capabilities across a huge repository of content.” 1 yang and hofmann anticipated the emergence of web-scale discovery with their evaluation of next generation catalogs. 2,3 by 2011, informed by yang and hofmann’s research, we believed that the systems in the marketplace were sufficiently evolved to make our efforts at assessing available systems worthwhile. this coincided nicely with an important objective in our strategic plan : f. william chickering (chick@rider.edu) is dean of university libraries, rider university, lawrenceville, new jersey. sharon q. yang (yangs@rider.edu) is associate professor–librarian at moore library, rider university, lawrenceville, new jersey. mailto:chick@rider.edu mailto:yangs@rider.edu evaluation and comparison of discovery tools: an update | chickering and yang 6 investigate link resolvers and discovery tools for federated searching and opac by summer 2011. heeding alexander pope’s advice to “be not the first by whom the new are tried, nor yet the last to lay the old aside,”4 we set about discovering what systems were in use throughout north america and which features each provided. some history in 2006, antelman, lynema, and pace observed that “library catalogs have represented stagnant technology for close to twenty years.” better technology was needed “to leverage the rich metadata trapped in the marc record to enhance collection browsing. the promise of online catalogs has never been realized. for more than a decade, the profession either turned a blind eye to problems with the catalog or accepted that it is powerless to fix them.” 6 dissatisfaction with catalog search tools led us to review the vufind discovery tool. while it had some useful features (spelling, “did you mean?” suggestions), it still suffered from inadequacies in full-text search and the cumbersome nature of searcher-designated boolean searching. it did not work well in searching printed music collections and, of course, only served as a catalog front end. with this all in mind, rul developed a set of objectives to improve information access for clients: • to provide information seekers with • an easy search option for academically valid information materials • an effective search option for academically valid information materials • a reliable search option for academically valid information materials across platforms • to recapture student academic search activity from google • to attempt revitalizing the use of monographic collections • to provide an effective mechanism to support offerings of e -books • to build a firm platform for appropriate library support of distance learning coursework literature review marshall breeding first discussed broad based discovery tools in 2005, shortly after the launch of google scholar. he posits that federated search could not compete with the power and speed of a tool like google scholar. he proclaims the need for, as he describes it, a “centralized search model.”7 information technology and libraries | june 2014 7 building on breeding’s observations four years earlier, diedrichs astutely observe d in 2009 that “user expectations for complete and immediate discovery and delivery of information have been set by their experiences in the web2.0 world. libraries must respond to the needs of those users whose needs can easily be met with google-like discovery tools, as well as those that require deeper access to our resources.”10 in that same year, dolski described the common situation in many academic libraries when in reference to the university of nevada las vegas (unlv) library he states, “our library website serves as the de facto gateway to our electronic, networked content offerings. yet usability studies have shown that findability, when given our website as a starting point, is poor. undoubtedly this is due, at least in part, to interface fragmentation.” 11 this perfectly described the way we had come to view rul’s situation. in 2010, breeding reviewed the systems in the market, noting that these are not just nextgeneration catalogs. he stressed “equal access to content in all forms,” a concept we now take for granted. a key virtue in discovery tools, he notes, is the “blending of the full text of journal articles and books alongside citation data, bibliographic, and authority records resulting in a powerful search experience. rather than being provided a limited number of access points selected by catalogers, each word and phrase within the text becomes a possible point of retrieval.” breeding further points out that: “web-scale discovery platforms will blur many of the restrictions and rules that we impose on library users. rather than having to explain to a user that the library catalog lists books and journal titles but not journal articles, users can simply begin with the concept, author, or title of interest and straightaway begin seeing results across the many formats within the library’s collection.”12 working with freshmen at rider university revealed that they are ahead of the professionals in approaching information this way, and we believed that web-scale discovery tools could help our users. as we began the process of selecting a discovery tool, we looked at the experiences of others. fabbi at the university of nevada las vegas (unlv) folded in a strong component of organizational learning in a highly structured manner that was unnecessary at rider. 13 no information was disclosed on the process of selecting a discovery vendor, though the website reveals the presence of a discovery tool (http://library.nevada.edu/). in contrast, many librarians at rider explored a variety of libraries’ application of search tools. following hofmann and yang’s work, a process of vendor demonstrations and analysis of feasibility led to a trial of ebsco discovery service. what we hoped for is what way at grand valley state reported in 2010 of his analysis of serials solutions’ summon: http://library.nevada.edu/ evaluation and comparison of discovery tools: an update | chickering and yang 8 an examination of usage statistics showed a dramatic decrease in the use of traditional abstracting and indexing databases and an equally dramatic increase in the use of full text resources from full text database and online journal collections. the author concludes that the increase in full text use is linked to the implementation of a web‐scale discovery tool.14 method understanding both rul’s objectives and the state of the art as reflected in the literature, we concluded that an up-to-date review of discovery tool adoptions was in order before moving forward in the process of selecting a product. 1. the resulting study included these steps: (1) compiling a list of all the major discovery tools, (2) developing a set of criteria for evaluation, (3) examining between four to seven websites where a discovery tool was deployed and evaluating each tool against each criteria, (4) recording the findings, and (5) analyzing the data. the targeted population for the study included all the major discovery tools in use in the united states. we define a discovery tool as a library user interface independent of any library systems. a discovery tool can be used to replace the opac module of an integrated library system or liv e sideby-side with the opac. other names for discovery tools include stand -alone opac, discovery layer, or discovery user interface. lately, a discovery tool is more often called a discovery service because most are becoming subscription-based and reside remotely in a cloud-based saas (software as a service) model. the authors compiled a list of fourteen discovery tools based on marshall breeding’s “major discovery products” guide published in “library technology guides.”15 those included aquabrowser library, axiell arena, bibliocommons (bibliocore), blacklight, ebsco discovery service, encore, endeca, extensible catalog, sirsidynix enterprise, primo, summon, visualizer, vufind, and worldcat local. two open-source discovery layers, sopac (the social opac) and scriblio, were excluded from this study because very few libraries are using them. for evaluation in this study, academic libraries were preferred over public libraries during the sample selection process. however, some discovery tools , such as bibliocommons, were more popular among public libraries. therefore examples of public library websites were included in the evaluation. the sites that made the final list were chosen either from the vendor’s website that maintained a customer list or breeding’s “library technology guides.”16 the following is the final list of libraries whose implementations were used in the study.

university at https://catalog.library.wmich.edu/vufind/ 7. yale university library at http://yufind.library.yale.edu/yufind/ the following list of criteria was used for the purpose of the evaluation. some were based on those used by the previous studies on discovery tools.17, 18, 19 the list embodied the librarians’ vision for the next-generation catalog and contained some of the most desirable features for a modern opac. the authors were aware of other desirable features for a discovery layer, and the following list was by no means the most comprehensive, but it served the purpose of the study well. 1. one-stop search for all library resources. a discovery tool should include all library resources in its search including the catalog with books and videos, journal articles in databases, and local archives and digital repository. this can be accomplished by the unified index or federated search, an essential component for a discovery tool. some of the discovery tools are described as web-scale because of their potential to search seamlessly across all library resources. 2. state-of-the-art web interface. a discovery tool should have a modern design similar to e-commerce sites, such as google, netflix, and amazon. 3. enriched content. discovery tools should include book cover images, reviews, and user driven input, such as comments, descriptions, ratings, and tag clouds. the enriched content can be either from library patrons, commercial sources, or both. 4. faceted navigation. discovery tools should allow users to narrow down the search results by categories, also called facets. the commonly used facets include locations, publication dates, authors, formats, and more. 5. simple keyword search box with a link to advanced search at the start page. a discovery tool should start with a simple keyword search box that looks like that of google or amazon. a link to the advanced search should be present. 6. simple keyword search box on every page. the simple keyword search box should appear on every page of a discovery tool. 7. relevancy. relevancy results criteria should take into consideration circulation statistics and books with multiple copies. more frequently circulated books indicate popularity and usefulness, and they should be ranked higher on the top of the display. a book of multiple copies may also be an indication of importance. http://lib.colostate.edu/ http://www.stolaf.edu/library/index.cfm http://mirlyn.lib.umich.edu/ https://catalog.library.wmich.edu/vufind/ http://yufind.library.yale.edu/yufind/ information technology and libraries | june 2014 13 8. “did you mean . . . ? spell-checking. when an error appears in the search, the discovery tool should correct the query spelling as a link so that users can simply click on it to get the search results. 9. recommendations/related materials. a discovery tool should recommend resources for readers in a similar manner to amazon or other e -commerce sites, based on transaction logs. this should take the form of “readers who borrowed this item also borrowed the following . . . ” or a link to recommended readings. it would be ideal if a discovery tool can recommend the most popular articles, a service similar to ex libris ’ bx usage-based services. 10. user contribution. user input includes descriptions, summaries, reviews, criticism, comments, rating and ranking, and tagging or folksonomies. 11. rss feeds. a modern opac should provide rss feeds. 12. integration with social networking sites. when a discovery tool is integrated with social networking sites, patrons can share links to library items with their friends on social networks like twitter, facebook, and delicious. 13. persistent links. records in a discovery tool contain a stable url capable of being copied and pasted and serving as a permanent link to that record. they are also called permanent urls. 14. auto-completion/stemming. a discovery tool is equipped with the computational algorithm that it can auto-complete the search words or supply a list of previously used words or phrases for users to choose from. google has stemming algorithms. 15. mobile compatibility. there is a difference between being “mobile compatible” and a “custom mobile website.” the former indicates a website can be viewed or used on a mobile phone, and the later denotes a different version of the user interface specially built for mobile use. in this study we include both as “yes.” 16. functional requirements for bibliographic retrieval (frbr). the latest development of rda certainly makes a discovery tool more desirable if it can display frbr relationships. for instance, a discovery tool may display and link different versions, editions or formats of a work, what frbr refers to as expressions and manifestations. for record keeping and analysis, a microsoft excel file with sixteen fields based on the above criteria was created. the authors checked the discovery tools on the websites of the selected libraries and recorded those features as present or absent. evaluation and comparison of discovery tools: an update | chickering and yang 14 rda compatibility is not used as a criterion in the study because most discovery tools allow users to add rda fields in marc. by now, all the discovery tools should be able to display, index, and search the new rda fields. findings one stop searching for all library resources—this is the most desirable feature when acquiring a discovery tool. unfortunately it also presented the biggest challenge for vendors. both librarians and vendors have been struggling with this issue for the past several years, yet no one has worked out a perfect solution. based on the examples the authors examined, this study found that only five out of fourteen discovery tools can retrieve articles from databases along with books, videos, and digital repositories. those include ebsco discovery service, encore, p rimo, summon, and worldcat local. whereas encore uses an approach similar to federated search performing live searches of databases, the other discovery tools build a single unified index. while the single unified index requires the libraries to send their catalog data and local information to the vendor for update and thus the discovery tools may fall behind in reflecting up to the minute accuracy in local holdings, federated search does real-time searching and does not lag behind in displaying current information. both approaches are limited in what they cover. both need permission from content providers for inclusion in the unified index or to develop a connection to article databases for real-time searching. for those discovery tools that do not have their own unified index or real-time searching capability, they provide web-scale searching through other means. for instance, vufind has developed connectors to application programming interfaces (apis) by serials solutions or oclc to pull search results from summon and worldcat local. encore not only developed its own realtime connection to electronic databases but is enhancing its web -scale search by incorporating the unified index from other discovery tools such as the ebsco discovery service. aquabrowse r is augmented by 360 federated search for the same purpose. despite of those possibilities, the authors did not find the article level retrieval in the sample discovery tools other than the main five mentioned above. comparing the coverage of each tools’ web-scale index can be challenging. ebsco, summon, and worldcat local publicize their content coverage on the web while primo and encore only share this information with their customers. this makes it hard to compare and evaluate the content coverage without contacting vendors and asking for that information. at present, none of the five discovery tools (ebsco discovery service, encore, primo, summon, and worldcat local) can boast 100% coverage of all library resources. in fact, none of the internet search engines, including google or google scholar, can retrieve 100% of all resources. therefore web -scale searching is more a goal than a possibility. apart from political and economic reasons, this is in part due to the nonbibliographic structure of the contents in databases such as scifinder and some others. one stop searching is still a work in progress because discovery tools provide students with a quick and simple way to retrieve a large number, but still an incomplete list of resources held by a information technology and libraries | june 2014 15 library. for more in-depth research, students are still encouraged to search the catalog, discipline specific databases, and digital repositories separately. state of the art interface—all the discovery tools are very similar in appearance to amazon.com. some are better than others. this study did not rate each discovery tool based on a scale and thus did not distinguish their fine degrees in appearance. rather each discovery tool is given a “yes” or “no.” the designation was based on subjective judgment. all the discovery tools received “yes” because they are very similar in appearance. enriched content—all the discovery tools have embedded book cover images or video jacket images, but some have displayed more, such as ratings and rankings, user -supplied or commercially available reviews, overviews, previews, comments, descriptions, title discussion, excerpts, or age suitability, just to name a few. a discovery tool may display enriched content by default out of box, but some may need to be customized to include it. the following is a list of enriched content implemented in each discovery tool that the authors found in the sample. the number in the last column indicates how many types of enriched content were found in the discovery tool at the time of the study. bibliocommons and aquabrowser stand out from the rest and made the top two on the list based on the number of enriched content from noncataloging sources (see figure 1). it is debatable how much nontraditional data a discovery tool should incorporate into its display. it warrants another discussion as to how useful such data is for users. faceted navigation—faceted navigation has become a standard feature in discovery tools over the last two years. it allows users to further divide search results into subsets based on predetermined terms. facets come from a variety of fields in marc records. some discovery tools have more facets than others. the most commonly seen facets include location or collections, publication dates, formats, author, genre, and subjects. faceted navigation is highly configurable as many discovery tools allow libraries to decide on their own facets. faceted navigation has become an integral part of a discovery tool. simple keyword search box on the starting page with a link to advanced search—the original idea is to allow a library’s user interface to resemble google by displaying a simple keyword search box with a link to advanced search at the starting page. most discovery tools provide the flexibility for libraries to choose or reject this option. however, many librarians find this approach unacceptable as they feel it lacks precision in searching and thus may mislead users. as the keyword box is highly configurable and up to the library to decide how they will present it, many libraries have added a pull down menu with options to search keywords, authors, titles, and locations. in doing so, the original intention for a google like simple search box is lost. therefore only a few libraries follow the goo gle-like box style at the starting page. most libraries altered the simple keyword search box on the starting page to include a dropdown menu or radio buttons, so the simple keyword search box is neither simple nor limited to keyword search only. nevertheless, this study gave all the discovery tools a “yes.” all the systems are capable of this feature even though libraries may choose not to use it. evaluation and comparison of discovery tools: an update | chickering and yang 16 rank discovery tool enriched

the ranked list of enriched content in discovery tools . simple keyword search box on every page—the feature enables a user to start a new search at every step of navigation in the discovery tool. most of the discovery tools provide such a box on the top of the screen as users navigate through the search results and record displays except extensible catalog and enterprise by sirsidynix. the feature is missing from the former while the latter almost has this feature except when displaying bib records in a pop-up box. information technology and libraries | june 2014 17 relevancy—traditionally, relevancy is uniformly based on a computer algorithm that calculates the frequency and relative position of a keyword (field weighting) in a record and displays the search results based on the final score. other factors have never been a part of the decision in the display of search results. in the discussion on next-generation catalogs, relevancy based on circulation statistics and other factors came up as a desirable possibility, and no discovery tool has met this challenge until now. primo by ex libris is the only one among the discovery tools under investigation that can sort the final results by popularity. “primo’s popularity ranking is calculated by use. this means that the more an item record has been clicked and viewed, the more popular it is.”20 even though those are not real circulation statistics, this is considered to be a revolutionary step and a departure from traditional relevancy. three years ago none of the discovery tools provided this option.21 to make relevancy ranking even more sophisticated, scholarrank, another service by ex libris, can work with primo to sort the search results not only based on a query match but also an item’s value score (its usage and number of citations) and a user’s characteristics and information needs. this shows the possibility of more advanced relevancy ranking in discovery tools. other vendors will most likely follow in the future incorporating more sophistication in their relevancy algorithms. spell checker/“did you mean . . . ?”—the most commonly observed way of correcting a misspelling in a query is, “did you mean . . . ?” but there are other variations providing the same or similar services. some of those variations are very user-friendly. the following is a list of different responses when a user enters misspelled words (see figure 2). “xxx” represents the keyword being searched. evaluation and comparison of discovery tools: an update | chickering and yang 18 discovery tools responses for misspelled search words notes acquabrowser did you mean to search: xxx, xxx, xxx? the suggested words are hyperlinks to execute new searches. axiell arena your original

leaves many information technology and libraries | june 2014 19 possibilities for local developers to add and develop. for instance, a diction ary or spell checker may be easily installed even if a discovery tool does not come with one out of the box. this feature may be configurable. 9. recommendation—amazon has one of those search engines with a recommendation system such as “customers who bought item a also bought item b.” the ecommerce recommendation algorithms analyze the activities of shoppers on the web and build a database of buyer profiles. the recommendations are made based on shopper behavior. when this applies to the library content, it could become “readers who were interested in item a were also interested in item b .” however, most discovery tools do not have a recommendation system. instead, they have adopted different approaches. most discovery tools make recommendations from bibliographic data in marc records such as subject headings for similar items. primo is one of the few discovery tools with a recommendation system similar to those used by amazon and other internet commercial sites. its bx article recommender service is based on usage patterns collected from its link resolver, sfx. developed by ex libris, bx is an independent service that integrates with primo well, but can serve as an add-on function for other discovery tools. bx is an excellent example that discovery tools can suggest new leads and directions for scholars in their research. the authors counted all the discovery tools that provide some kind of recommendations regardless of their technological approaches using marc data or algorithms. ten out of fourte en discovery tools provide this feature in various forms (see figure 3). those include axiell arena, bibliocommons, ebsco discovery service, encore, endeca, extensible catalog, primo, summon, worldcat local, and vufind. the following are some of the recommendations found in those discovery tools. the authors did not find any recommendation in the libraries that use aquabrowser, enterpri se, visualizer, or blacklight. discovery tools language used for recommending or linking to related items axiell arena “see book recommendations on this topic” “who else writes like this?” bibliocommons “similar titles & subject headings & lists that include this title” ebsco discovery service “find similar results” encore “other searches you may try” “additional suggestions” endeca “recommended titles for. . . . view all recommended titles that match your search” evaluation and comparison of discovery tools: an update | chickering and yang 20 “more like this” extensive catalog “more like this” “searches related to . . . ” primo “suggested new searches by this author” “suggested new searches by this subject” “users interested in this article also expressed an interest in the following:” summon “search related to . . . ” worldcat local “more like this” “similar items” “related subjects” “user lists with this item” vufind “more like this” “similar items” “suggested topics” “related subjects” figure 3. language used for recommendation. some discovery tool recommendations are designed in a more user friendly manner than others. most recommendations exist exclusively for items. ideally, a discovery tool should provide an article recommendation system like ex libris’ bx usage-based service that will show users the most frequently used and most popular articles. at the time of this evaluation, no discovery tool has incorporated an article recommendation system except primo. research is needed to evaluate how patrons utilize recommendation services or if they find recommendations beneficial in discovery tools. user contribution—traditionally, bibliographic data has been safely guarded by cataloging librarians for quality control. it has been unthinkable that users would be allowed to add data to library records. the internet has brought new perspectives on this issue. half of the discovery tools (7) under evaluation provide this feature to varying degrees (see figure 4). designed primarily for public libraries, bibliocommons seems the most open to user -supplied data among information technology and libraries | june 2014 21 all the discovery tools. many other discovery tools (7) allow users to contribute tags and reviews. all the discovery tools allow librarians to censor user -supplied data before releasing it for public display. the following figure is a summary of the types of data these discove ry tools allow users to enter. ranking discovery tool user contribution 1 bibliocommons tags, similar title, private note, notices, age suitability, summary, quotes, video, comments, and ratings (10) 2 aquabrowser tags, reviews, and ratings/rankings (3) axiell arena tags, reviews, and title discussions (3) vufind tags, reviews, comments (3) 3 primo tags and reviews (2) worldcat local tags and reviews (2) 4 encore tags (1) 5 blacklight (0) endeca (0) enterprise (0) extensible catalog (0) summon (0) visualizer (0) figure 4. discovery tools based on user contribution. past research indicates that folksono mies or tags are highly useful.22 they complement librarycontrolled vocabularies, such as library of congress subject headings, and increase access to library collections. a few discovery tools allow user entered tags to form “word clouds.” the relative importance of tags in a word cloud is emphasized by font color and size. a tag list is another way to organize and display tags. in both cases , tags are hyperlinked to a relevant list of items. some tags serve as keywords to start new searches, while others narrow search results. only four discovery tools, aquabrowser, encore, primo, and worldcat local, provide both tag clouds and lists. bibliocommons provides only tag lists for the same purpose. the rest of the discovery tools do not have either. one setback of user-supplied tags for subject access is their evaluation and comparison of discovery tools: an update | chickering and yang 22 incomplete nature. they may lead users to partial retrieval of information as users add tags only to items that they have used. the coverage is not systematic and inclusive of all collections. therefore data supplied by users in discovery tools remains controversial. it is possible to seed systems with folksonomies using services like librarything for libraries, which could reduce the impact of this issue. rss feed/email alerts—this feature can automatically send a list of new library resources to users based on his or her search criteria. it can be useful for experienced researchers or frequent library users. some discovery tools may use email alerts as well. eight out of fourteen discovery tools in this evaluation provide rss feeds. those with rss feeds include aquabrowser, axiell arena, ebsco discovery service, endeca, enterprise, primo, summon, and vufind. an rss feed can be added as a plug-in in some discovery tools if it does not come as part of the base system. integration with social networking sites—as most of the college students participate in social networking sites, this feature provides an easy way to share resources among college s tudents on social networking sites. users can place the link to a resource by clicking on an icon in the discovery tool and share the resource with friends on facebook, twitter, delicious and many other social network sites. nine out of the fourteen discovery tools provide this feature. some discovery tools provide integration possibilities with many more social networking sites than others. those with this feature include aquabrowser, axiell arena, bibliocommons, ebsco discovery service, encore, endeca, primo, worldcat local, and extensible catalog. so far , the interaction between discovery tools and social networking sites is limited to sharing resources. social networking sites should be carefully evaluated for the possibility of integra ting some of their popular features into discovery tools. persistent link—this is also called permanent link or permurl. not all the links displayed in a browser location box are persistent links, therefore some discovery tools specifically provid e a link in the records for users to copy and keep. five out of fourteen discovery tools explicitly listed this link in records. those include aquabrowser, axiell arena, blacklight, ebsco discovery service, and worldcat local. the authors marked a system a s “no” when a permanent link is not prominently displayed in a discovery tool. in other words, only those discovery tools that explicitly provide a persistent link are counted as “yes.” however, the url in a browser’s location box during the display of a record may serve as a persistent link in some cases. for instance, vufind does not provide a permanent url in the record, but indicates on the project site that url in the location box is a persistent link. auto-completion/stemming—when a user types in keywords in the search box, the discovery tool will supply a list of words or phrases that she or he can choose readily. this is a highly useful feature that google excels at. stemming not only automatically completes the spelling of a keyword, but also supplies a list of phrases that point to existing items. the authors found this feature in six out of fourteen discovery tools. they include axiell arena, endeca, enterprise, extensible catalog, summon, and worldcat local. information technology and libraries | june 2014 23 mobile interface—the terms “mobile compatible” and “mobile interface” are two different concepts. a mobile interface is a simplified version of a normal browser version of a discovery tool interface so it is optimized for use on mobile phones , and the authors only counted those discovery tools that have a separate mobile interface. a discovery tool may be mobile friendly or compatible and does not necessarily need a separate mobile interface. many discovery tools, such as ebsco, can detect the request from a mobile phone and automatically direct the request to the mobile interface. eleven out of fourteen claim to provide a separate mobile interface. blacklight, enterprise, and extensible catalog do not seem to have a separate mobile interface even though they may be mobile friendly. frbr—frbr groupings denote the relationships between work, manifestation, expression, and items. for instance, a search will not only retrieve a title, but different editions and formats of the work. only three discovery tools can display frbr relationships: extensible catalog (open source), primo by ex libris, and worldcat local by oclc. so far , most discovery tools are not capable of displaying the manifestations and expressions of a work in a meaningful way. from the user’s point of view, this feature is highly desirable. figure 5 is a screenshot from primo demonstrating displays indicating a large number of different adaptations of the work “romeo and juliet.” figure 6 displays the same intellectual work in different manif estations such as dvd, vhs, books, and more. figure 5. display of frbr

blacklight displays fewer advanced features, but seems flexible for users to add features. see figures 7, 8, and 9. information technology and libraries | june 2014 25 figure 7. proprietary discovery

discovery tool, this consideration placed five discovery tools above the rest: encore, ebsco discovery service, primo, summon, and worldcat local ( see figure 10). these five are web-scale discovery services. all of them use their native unified index except encore, which has incorporated the ebsco unified index in its search. despite of great progress made in the past three years in one-stop searching, none of the discovery to ols can truly search across all library resources—all of them have some limitations as to the coverage of content. each unified index may cover different databases as well as overlap each other in many areas. one possible solution may lie in a hybrid approach that combines a unified index with federated search (also called real-time discovery). those old and new technologies may work well when complementing each other. it remains a challenge if libraries will ever have one-stop searching in its true sense. discovery tools one-stop searching encore yes ebsco discovery service yes primo yes summon yes worldcat local yes figure 10. the discovery tools capable of one stop searching . it is also worth mentioning that one-stop searching is a vital and central piece of discovery tools. those discovery tools without a native unified index or connectors to databases for real -time searching are at a disadvantage. therefore discovery tools that do not provide web -scale searching are investigating various possibilities to incorporate one-stop searching. some are drawing on the unified indexes of those discovery tools that have them through connectors to the application programming interfaces (apis) of those products. for instance, vufind in cludes connectors to the apis of a few other systems that have a unified index or vast resources such as summon and worldcat. blacklight may provide one-stop searching through the primo api. such a practice may present other problems such as calculating relevancy ranking across resources that may not live in the same centralized index, thus not achieving fully balanced relevancy ranking. nevertheless, discovery tool developers are working hard to achieve one-stop searching. as a unified index can be shared across discovery tools, in the next few years, more and more discovery services may offer one-stop searching. evaluation and comparison of discovery tools: an update | chickering and yang 28 based on the count of the sixteen criteria in the checklist, we ranked primo and worldcat local as the top two discovery tools. based on our criteria , primo has two unique features that make it stand out: relevancy enhanced by usage statistics and value score and the frbr relationship display. worldcat local and extensible catalog are the other two discov ery tools that can display frbr relationships (see figure 11). rank discovery tools number of advanced features 1 primo and worldcat local 14/16 2 axiell arena 13/16 3 ebsco discovery service 12/16 4 aquabrowser, encore, and endeca

through new releases and improvements, what is true today may b e false tomorrow. discovery tools constantly improve and evolve , and many features are not included in this evaluation, such as integration with google maps for the location of an item and user-driven acquisitions. innovations are added to discovery tools constantly. this study only covers the most common features that the library community agreed upon as those that a discovery tool should have. some open-source discovery tools may provide a skeleton of an application that leaves the code open for users to develop new features. therefore different implementations of an open-source discovery tool may encompass totally different features that are not part of the core application. for instance, the university of virginia developed virgo based on blacklight, adding many advanced features. thus it is quite a challenge to distinguish what comes with the software and what are local developments. this study focused on the user interface of discovery tools. what are not included are content coverage, application administration, and searching capability of the discovery tools. those three are important factors when choosing a discovery tool. conclusion search technology has evolved far beyond federated searching. the concept of a “next generation catalog” has merged with this idea, and spawned a generation of discovery tools bringing almost google-like power to library searching. the problems facing libraries now are the intelligent information technology and libraries | june 2014 29 selection of a tool that fits their contexts, and structuring a process to adopt a nd refine that tool to meet the objectives of the library. our findings indicate that primo and worldcat local have better user interfaces, displaying more advanced features of a next generation catalog than their peers. for rul, ebsco discovery service (eds) provides something approaching the ease of google searching from either a single search box or a very powerful advanced search. being aware of the limitations noted above, rider’s libraries elected to continue displaying traditional search options in addition to what we’ve branded “library one search.” another issue we discovered in this process is when negotiating for a vendor-hosted test, libraries must be sure that the test period begins when the configuration is complete rather than only whe n the data load begins. all phases of the project took far more time than anticipated. the client institution’s implementation coordinator or team needs to be reviewing the progress on a daily basis and communicating often with the vendor-based implementation team. with the evaluative framework this study provides, libraries moving toward discovery tools should consider changing capabilities of the available discovery tools to make informed choices. references 1. jason vaughan, “investigations into library web-scale discovery

library automation vol. 14/1 march 1981 publishing firm. with a feeling of deja vu i listened to an explanation of how difficult it is to develop a system for the novice; one proposed solution is to allow only the first four letters of a word to be entered (one of the search methods used at the library of congress, which does suggest some cross-fertilization ). whatever the trends, the reality is that librarians and information scientists are playing decreasing roles in the growth of information display technology. hardware systems analysts, advertisers, and communications specialists are the main professions that have an active role to play in the information age. perhaps the answer is an immediate and radical change in the training of library schools of today. our small role may reflect our penchant to be collectors, archivists, and guardians of the information repositories . have we become the keepers of the system? the demand today is for service, information, and entertainment. if we librarians cannot fulfill these needs our places are not assured. should the american library association (ala) be ensuring that libraries are a part of all ongoing tests of videotex-at least in some way-either as organizers, information providers, or in analysis? consider the force of the argument given at the ala 1980 new york annual conference that cable television should be a medium that librarians become involved with for the future. certainly involvement is an important role, but we , like the industrialists and marketers before us, must make smart decisions and choose the proper niche and the most effective way to use our limited resources if we are to serve any part of society in the future. bibliography 1. electronic publishing revietc. oxford, england : learned information

sherry cook, mercedes dumlao, and maria szabo: bechtel data processing library, san francisco, california. the 1980s are here and with them comes the ever broadening application of the computer. this presents a new challenge to libraries. what do we do with all these computer codes? how do we index the material? and most importantly, how do we make it accessible to our patrons or computer users? bechtel's data processing library has met these demands. the genesis for th e collection was bechte l's conversion from a honeywell 6000 computer to a univac lloo in 1974. all the programs in use at that time were converted to run on the univac system. it seemed a good time to put all of the computer programs together from all of the various bechtel divisions into a controlled collection. the librarians were charged with the responsibility of enforcing standards and control of bechtel's computer programs. the major benefits derived from placing all computer programs into a controlled library were: 1. company-wide usage of the programs. 2. minimize investment in program development through common usage. 3. computer file and documentation storage by the library to safeguard the investment. 4. central location for audits of program code and documentation. 5. centralized reporting on bechtel programs . developing the collection involved basic cataloging techniques which were greatly modified to encompass all the information that computer programs generate, including actual code, documentation, and listings . historically, this information must be kept indefinitely on an archival basis . the machine-readabl e codes themselves are grouped together and maintained from the library's budget . finally , a reference desk is staffed to answer questions from the entire user community. documentation for programs is strictly controlled . code changes are arranged chronologically to provide only the most current release of a program to all users. historical information is kept and is crucial to satisfy the demands of auditors (such as the nuclear regulatory commission). additionally, the names of people administratively connected with the program are recorded and their responsibilities communications 53 defined (valuable in situations of liability for work complete d yesteryear). the backbone of the operation is a standards manual that spells out and discusses the file requirements, documentation specifications, and control forms. this standard is made readily available throughout bechtel. in addition, there are in-house education classes about the same document. indeed, the central data processing library is the repository of computer information at bechtel. the centralization and control of computer programs eliminates the chaos that can occur if too many individuals maintain and use the same computer program . 110 information technology and libraries | september 2009 employing virtualization in library computing: use cases and lessons learned arwen hutt, michael stuart, daniel suchy, and bradley d. westbrook this paper provides a broad overview of virtualization technology and describes several examples of its use at the university of california, san diego libraries. libraries can leverage virtualization to address many long-standing library computing challenges, but careful planning is needed to determine if this technology is the right solution for a specific need. this paper outlines both technical and usability considerations, and concludes with a discussion of potential enterprise impacts on the library infrastructure. o perating system virtualization, herein referred to simply as “virtualization,” is a powerful and highly adaptable solution to several library technology challenges, such as managing computer labs, automating cataloging and other procedures, and demonstrating new library services. virtualization has been used in one manner or another for decades,1 but it is only within the last few years that this technology has made significant inroads into library environments. virtualization technology is not without its drawbacks, however. libraries need to assess their needs, as well as the resources required for virtualization, before embarking on large-scale implementations. this paper provides a broad overview of virtualization technology and explains its benefits and drawbacks by describing some of the ways virtualization has been used at the university of california, san diego (ucsd) libraries.2 n virtualization overview virtualization is used to partition the physical resources (processor, hard drive, network card, etc.) of one computer to run one or more instances of concurrent, but not necessarily identical, operating systems (oss). traditionally only one instance of an operating system, such as microsoft windows, can be used at any one time. when an operating system is virtualized—creating a virtual machine (vm)—the vm communicates through virtualization middleware to the hardware or host operating system. this middleware also provides a consistent set of virtual hardware drivers that are transparent to the enduser and to the physical hardware. this allows the virtual machine to be used in a variety of heterogeneous environments without the need to reconfigure or install new drivers. with the majority of hardware and compatibility requirements resolved, the computer becomes simply a physical presentation medium for a vm. n two approaches to virtualization: host-based vs. hypervisor virtualization can be implemented using type 1 or type 2 hypervisor architectures. a type 1 hypervisor (figure 1), commonly referred to as “host-based virtualization,” requires an os such as microsoft windows xp to host a “guest” operating system like linux or even another version of windows. in this configuration, the host os treats the vm like any other application. host-based virtualization products are often intended to be used by a single user on workstation-class hardware. in the type 2 hypervisor architecture (figure 2), commonly referred to as “hypervisor-based virtualization,” the virtualization middleware interacts with the computer’s physical resources without the need of a host operating system. such systems are usually intended for use by multiple users with the vms accessed over the network. realizing the full benefits of this approach requires a considerable resource commitment for both enterprise-class server hardware and information technology (it) staff. n use cases archivists’ toolkit the archivists’ toolkit (at) project is a collaboration of the ucsd libraries, the new york university libraries, and the five colleges libraries (amherst college, hampshire college, mt. holyoke college, smith college, and university of massechusetts, amherst) and is funded by the andrew w. mellon foundation. the at is an open-source archival data management system that provides broad, integrated support for the management of archives. it consists of a java client that connects to a relational database back-end (mysql, mssql, or oracle). the database can be implemented on a networked server or a single workstation. since its initial release in december 2006, the at has sparked a great deal of interest and rapid uptake of the application within the archival community. this growing interest has, in turn, created an increased demand for demonstrations of the product, workshops and training, and simpler methods for distributing the application. (of the use cases described here, the two for the at arwen hutt (ahutt@ucsd.edu) is metadata specialist, michael stuart (mstuart@ucsd.edu) is information technology analyst, daniel suchy (dsuchy@ucsd.edu) is public services technology analyst, and bradley d. westbrook (bradw@library.ucsd.edu) is metadata librarian and digital archivist, university of california, san diego libraries. employing virtualization in library computing | hutt et al. 111 distribution and laptop classroom are exploratory, whereas the rest are in production.) at workshops the society of american archivists sponsors a two-day at workshop occurring on multiple dates at several locations. in addition, the at team provides oneand two-day workshops to different institutional audiences. at workshops are designed to give participants a hands-on experience using the at application. accomplishing this effectively requires, at the minimum, supplying all participants with identical but separate databases so that participants can complete the same learning exercises simultaneously and independently without concern for working in each other’s space. in addition, an ideal configuration would reduce the workload of the instructors, freeing them from having to set up the at instructional database onsite for each workshop. for these workshops we needed to do the following: n provide identical but separate databases and database content for all workshop attendees n create an easily reproducible installation and setup for workshops by preparing and populating the at instructional database in advance virtualization allows the at workshop instructors to predefine the workstation configuration, including the installation and population of the at databases, prior to arriving at the workshop site. to accomplish this we developed a workshop vm configuration with mysql and the at client installed within a linux ubuntu os. the workshop instructors then built the at vm with the data they require for the workshop. the at client and database are loaded on a dvd or flash drive and shipped to the classroom managers at the workshop sites, who then need only to install a copy of the vm and the freely available vmplayer software (necessary to launch the at vm) onto each workstation in the classroom. the at vm, once built, can be used many times both for multiple workstations in a classroom as well as for multiple workshops at different times and locations. this implementation has worked very well, saving both time and effort for the instructors and classroom support staff by reducing the time and communication figure 1. a type 1 hypervisor (host-based) implementation figure 2. a type 2 hypervisor-based implementation 112 information technology and libraries | september 2009 necessary for deploying and reconfiguring the vm. it also reduces the chances that there will be an unexpected conflict between the application and the host workstation’s configuration. but the method is not perfect. more than anything else, licensing costs motivated us to choose linux as the operating system instead of a proprietary os such as windows. this reduces the cost of using the vm, but it also requires workshop participants to use an os with which they are often unfamiliar. for some participants, unfamiliarity with linux can make the workshop more difficult than it would be if a more ubiquitous os was used. at demonstrations in a similar vein, members of the at team are often called upon to demonstrate the application at various professional conferences and other venues. these demonstrations require the setup and population of a demonstration database with content for illustrating all of the application’s functions. one of the constraints posed by the demonstration scenario is the importance of using a local database instance rather than a networked instance, since network connections can be unreliable or outright unavailable (network connectivity being an issue we’ve all faced at conferences). another constraint is that portions of the demonstrations need some level of preparation (for example, knowing what search terms will return a nonempty result set), which must be customized for the unique content of a database. a final constraint is that, because portions of the demonstration (import and data merging) alter the state of the database, changes to the database must be easily reversible, or else new examples must be created before the database can be reused. building on our experience of using virtualization to implement multiple copies of an at installation, we evaluated the possibility of using the same technology for simplifying the setup necessary for demonstrating the at. as with the workshops, the use of a vm for at demonstrations allows for easy distribution of a prepopulated database, which can be used by multiple team members at disparate geographic locations and on different host oss. this significantly reduces the cost of creating (and recreating) demonstration databases. in addition, demonstration scripts can be shared between team members, creating additional time savings as well as facilitating team participation in the development and refinement of the demonstration. perhaps most important is the ability to roll back the vm to a specific state or snapshot of the database. this means the database can be quickly returned to its original state after being altered during a demonstration. overall, despite our initial anxiety about depending on the vm for presentations to large audiences, this solution has proven very useful, reliable, and cost-effective. at distribution implementing the at requires installing both the toolkit client and a database application such as mysql, instantiating an at database, and establishing the connection between database and client. for many potential customers of the at, the requirements for database creation and management can be a significant barrier due to inexperience with how such processes work and a lack of readily available it resources. many of these customers simply desire a plug-and-play version of the application that they can install and use without requiring technical assistance. it is possible to satisfy this need for a plug-and-play at by constructing a vm containing a fully installed and ready-to-use at application and database instance. this significantly reduces the number and difficulty of steps involved in setting up a functional at instance. the customer would only need to transfer the vm from a dvd or other source to their computer, download and install the vm reader, and then launch the at vm. they would then be able to begin using the at immediately. this removes the need for the user to perform database creation and management; arguably the most technically challenging portion of the setup process. users would still have the option of configuring the application (default values, lookup lists, etc.) in accord with the practices of their repository. batch processing catalog records the rapid growth of electronic resources is significantly changing the nature of library cataloging. not only are types of library materials changing and multiplying, the amount of e-resources being acquired increases each year. electronic book and music packages often contain tens of thousands of items, each requiring some level of cataloging. because of these challenges, staff are increasingly cataloging resources with specialized programs, scripts, and macros that allow for semiautomated record creation and editing. such tools make it possible to work on large sets of resources—work that would not be financially possible to perform manually item by item. however, the specialized configuration of the workstation required for using these automated procedures makes it very difficult to use the workstation for other purposes at the same time. in fact, user interaction with the workstation while the process is running can cause a job to terminate prior to completion. in either scenario, productivity is compromised. virtualization offers an excellent remedy to this problem. a virtual machine configured for semiautomated batch processing allows for unused resources on the workstation to process the batch requests in an isolated environment while, at the same time and on the same machine, the user is able to work on other tasks. in cases employing virtualization in library computing | hutt et al. 113 where the user’s machine is not an ideal candidate for virtualization, the vm can be hosted via a hypervisorbased solution, and the user can access the vm with familiar remote access tools such as remote desktop in windows xp. secure sandbox in addition to challenges posed by increasingly large quantities of acquisitions, the ucsd libraries is also encountering an increasing variety of library material types. most notable is the variety and uniqueness of digital media acquired by the library, such as specialized programs to process and view research data sets, new media formats and viewers, and application installers. cataloging some of these materials requires that media be loaded and that applications be installed and run to inspect and validate content. but running or opening these materials, which are sometimes from unknown sources, poses a security risk to both the user’s workstation and to the larger pool of library resources accessible via the network. many installers require a user to have administrative privileges, which can pose a threat to network security. the virtual machine allows for a user to have administrative privileges within the vm, but not outside of the vm. the user can be provided with the privileges needed for installing and validating content without modifying their privileges on the host machine. in addition, the vm can be isolated by configuring its network connection so that any potential security risks are limited to the vm instance and do not extend to either the host machine or the network. laptop classroom instructors at the ucsd libraries need a laptop classroom that meets the usual requirements for this type of service (mobility, dependability, etc.) but also allows for the variety of computing environments and applications in use throughout our several library locations. in a least-common-denominator scenario, computers are configured to meet a general standard (usually microsoft windows with a standard browser and office suite) and allow minimal customization. while this solution has its advantages and is easy to configure and maintain from the it perspective, it leaves much to be desired for an instructor who needs to use a variety of tools in the classroom, often on demand. the goal in this case is not to settle for a single generic build but instead look for a solution that accommodats three needs: n the ability to switch quickly between different customized os configurations n the ability to add and remove applications on demand in a classroom setting n the ability to restore a computer modified during class to its original state of course, regardless of the approach taken, the laptops still needed to retain a high level of system security, application stability, and regular hardware maintenance. after a thorough review of the different technologies and tools already in use in the libraries, we determined that virtualization might also serve to meet the requirements of our laptop classroom. the need to support multiple users and multiple vms makes this scenario an ideal candidate for hypervisor-based virtualization. we decided to use vdi (virtual desktop infrastructure), a commercially available hypervisor product from vmware. vmware is one of the largest providers of virtualization software, and we were already familiar with several iterations of its host-based vm services. the core of our project plan consists of a base vm to be created and managed by our it department. to support a wide variety of applications and instruction styles, instructors could create a customized vm specific to their library’s instruction needs with only nominal assistance from it staff. the custom vm would then be made available on demand to the laptops from a central server (as depicted in figure 2 above). in this manner, instructors could “own” and maintain a personal instructional computing environment, while the classroom manager could still ensure the laptop classroom as a whole maintained the necessary secure software environment required by it. as an added benefit, once these vms are established, they could be accessed and used in a variety of diverse locations. n considerations for implementation before implementing any virtualization solution, in-depth analysis and testing is needed to determine which type of solution, if any, is appropriate for a specific use case in a specific environment. this analysis should include three major areas of focus: user experience, application performance in the virtualized environment, and effect on the enterprise infrastructure. in this section of this paper, we review considerations that, in hindsight, we would have found to be extremely valuable in the ucsd libraries’ various implementations of virtualization. user experience traditionally, system engineers have developed systems and tuned performance according to engineering metrics (e.g., megabytes per second and network latency). while such metrics remain valuable to most assessments of a 114 information technology and libraries | september 2009 computer application, performance assessments are being increasingly defined by usability and user experience factors. in an academic computing environment, especially in areas such as library computer labs, these newer kinds of performance measures are important indicators of how effectively an application performs and, indirectly, of how well resources are being used. virtualization can be implemented in a way that allows library users to have access to both the virtualized and host oss or to multiple virtualized oss. since virtualization essentially creates layers within the workstation, multiple os layers (either host or virtualized) can cause the users to become confused as to which os they are interacting with at a given moment. in that kind of implementation, the user can lose his or her way among the host and guest oss as well as become disoriented by differing features of the virtualized oss. for example, the user may choose to save a file to the desktop, but may not be aware that the file will be saved to the desktop of the virtualized os and not the host os. external device support can also be problematic for the end user, particularly with regard to common devices such as flash drives. the user needs to be aware of which operating system is in use, since it is usually the only one with which an external device is configured to work. authentication to a system is another example of how the relationship between the host and guest os can cause confusion. the introduction of a second os implicitly creates a second level of authentication and authorization that must be configured separately from that of the host os. user privileges may differ between the host and guest os for a particular vm configuration. for instance, a user might need to remember two logins or at least enter the same login credentials twice. these unexpected differences between the host and guest os produce negative effects on a user’s experience. this can be a critical factor in a time-sensitive environment such as a computer lab, where the instructor needs to devote class time to teaching and not to preparing the computers for use and navigating students through applications. interface latency and responsiveness latency (meaning here the responsiveness or “sluggishness” of the software application or the os) in any interface can be a problem for usability. developers devote a significant amount of time to improving operating systems and application interfaces to specifically address this issue. however, users will often be unable to recognize when an application is running a virtualized os and will thus expect virtualized applications to perform with the same responsiveness as applications that are not-virtualized. in our experience, some vm implementations exhibit noticeable interface latency because of inherent limitations of the virtualization software. perhaps the most notable and restrictive limitation is the lack of advanced 3d video rendering capability. this is due to the lack of support for hardware-accelerated graphics, thus adding an extra layer of communication between the application and the video card and slowing down performance. in most hardware-accelerated 3d applications (e.g., google earth pro or second life), this latency is such a problem that the application becomes unusable in a virtualized environment. recent developments have begun to address and, in some cases, overcome these limitations.3 in every virtualization solution there is overhead for the virtualization software to do its job and delegate resources. in our experience, this has been found to cause an approximately 10–20 percent performance penalty. most applications will run well with little or moderate changes to configuration when virtualized, but the overhead should not be overlooked or assumed to be inconsequential. it is also valuable to point out that the combination of applications in a vm, as well as vms running together on the same host, can create further performance issues. traditional bottlenecks the bottlenecks faced in traditional library computing systems also remain in almost every virtualization implementation. general application performance is usually limited by the specifications of one or more of the following components: processor, memory, storage, and network hardware. in most cases, assuming adequate hardware resources are available, performance issues can be easily addressed by reconfiguring the resources for the vm. for example, a vm whose application is memorybound (i.e., performance is limited by the memory available to the vm), can be resolved by adjusting the amount of memory allocated to the vm. a critical component of planning a successful virtualization deployment includes a thorough analysis of user workflow and the ways in which the vm will be utilized. although the types of user workflows may vary widely, analysis and testing serve to predict and possibly avoid potential bottlenecks in system performance. enterprise impact when assessing the effect virtualization will have on your library infrastructure, it is important to have an accurate understanding of the resources and capabilities that will form the foundation for the virtualized infrastructure. it is a misconception that it is necessary to purchase stateof-the-art hardware to implement virtualization. not only are organizations realizing how to utilize existing hardware better with virtualization for specific projects, they are discovering that the technology can be extended employing virtualization in library computing | hutt et al. 115 to the rest of the organization and be successfully integrated into their it management practices. virtualization does, however, impose certain performance requirements for large-scale deployments that will be used in a 24/7 production environment. in such scenarios, organizations should first compare the level of performance offered by their current hardware resources with the performance of new hardware. the most compelling reasons to buy new servers include the economies of scale that can be obtained by running more vms on fewer, more robust servers, as well as the enhanced performance supplied by newer, more virtualization-aware hardware. in addition, virtualization allows for resources to be used more efficiently, resulting in lower power consumption and cooling costs. also, the network is often one of the most overlooked factors when planning a virtualization project. while a local virtualized environment (i.e., a single computer) may not necessarily require a high performance network environment, any solution that calls for a hypervisor-based infrastructure requires considerable planning and scaling for bandwidth requirements. the current network hardware available in your infrastructure may not perform or scale adequately to meet the needs of this vm use. again, this highlights the importance of thorough user workflow analyses and testing prior to implementation. depending on the scope of your virtualization project, deployment in your library can potentially be expensive and can have many indirect costs. while the initial investment in hardware is relatively easy to calculate, other factors, such as ongoing staff training and system administration overhead, are much more difficult to determine. in addition, virtualization adds an additional layer to oftentimes already complex software licensing terms. to deal with the increased use of virtualization, software vendors are devoting increasing attention to the intricacies of licensing their products for use in such environments. while virtualization can ameliorate some licensing constraints (as noted in the at workshop use case), it can also conceal and promote licensing violations, such as multiple uses of a single-license applications or access to license-restricted materials. license review is a prudent and highly recommended component of implementing a virtualization solution. finally, concerning virtualization software itself, it also should be noted that while commercial vm companies usually provide plentiful resources for aiding implementation, several worthy open-source options also exist. as with any opensource software, the total cost of operation (e.g., the costs of development, maintenance, and support) needs to be considered. n conclusion as our use cases illustrate, there are numerous potential applications and benefits of virtualization technology in the library environment. while we have illustrated a number of these, many more possibilities exist, and further opportunities for its application will be discovered as virtualization technology matures and is adapted by a growing number of libraries. as with any technology, there are many factors that must be taken into account to evaluate if and when virtualization is the right tool for the job. in short, successful implementation of virtualization requires thoughtful planning. when so implemented, virtualization can provide libraries with cost-effective solutions to long-standing problems. references and notes 1. alessio gaspar et al., “the role of virtualization in computing education,” in proceedings of the 39th sigcse technical symposium on computer science

exist.” mark cyzyk information technology and libraries | june 2013 4 often, i find myself trolling online forums, searching for and praying i find a bona-fide solution to a technical problem. typically, my process begins with the annoying discovery that many others are running into the same, or very similar, difficulty. many others. once i get over my initial frustration ("why isn't this problem fixed by now?"), i proceed to read, to attempt to determine which of the often conflicting and even contradictory suggestions for fixing the problem might actually work. i thought it would be instructive to step back for a moment and examine this experience. to do so, i want to use as my example, as my straw man, not a technical question, but a more generic question, the sort of question anyone might conceivably ask. i'll ask this question, then i'll list what i think might be answers, in form and substance, from the technical forums had it been asked there: "i want to go to india. how best to get there?" why would you want to go there? you could fly. you could take a ship. why go to india? iceland is much better. i went to india once and it wasn't that great. you never specify where in india you want to go. we can't help you until you tell us where in india you want to go. i am sick and tired of these people who don't read the forums. your query has been answered before. the only way to get there is to fly first class on continental. you could ride a mule to india. new zealand is much better. you should go there instead. it is impossible to go to india. you can get from india to anywhere in europe very easily via india air. you should read a passage to india, i forget who wrote it. i read it as an undergraduate. it was very good. you are an idiot for wanting to go to india. india does not exist. mark cyzyk (mcyzyk@jhu.edu), a member of lita and the ital editorial board, is the scholarly communication architect in the sheridan libraries, the johns hopkins university, baltimore, maryland. mailto:mcyzyk@jhu.edu editorial board thoughts: india does not exist | cyzyk 5 i think it's safe to say that the signal to noise ratio here is high. if we truly want to answer a question, we don't want to add noise. pontificating, posturing, and automatically posing as a mentor in a mentor/protégé relationship will typically be construed as adding nothing but noise to the signal. in most cases, we who answer such questions are not here to educate, except insofar as we provide a clear and concise answer to a technical query issued by one of our peers. what should we assume? first off, we should assume that the person writing the question is sincere: he truly does want to go to india. we need not question his motives. the best way to think about this is that the query is a hypothetical: if he were to want to go to india, how best to do it? if you were to want to go to india, how best to do it? this requires a certain level of empathy on the part of the one answering the question, a level of empathy of which the technical forums are all but devoid. many answers on those forums are so tone-deaf to human need they may as well have been written by robots. "how best to get there" is tricky because you must make some assumptions. assumptions are fine as long as you're explicit about them. one assumption might be: he is leaving from the east coast of the united states. another assumption might be: he is going to india only for a short while, for a conference or vacation. yet another one might be: by "best" he means "quickest, most efficient, least expensive." stating these assumptions, then stating your answer to the question, is appropriate and is what is most helpful. stating your assumptions is tantamount to stating your understanding of the original question, its scope and context. this is always a helpful thing to do when attempting to communicate with another human being. now, communication and plumbing the depth of human need, at least with respect to informational and bibliographic needs, has always been a strong suit of librarians, so what i write here is not really directed at librarians. it is, though, directed at we who straddle both the library world and the technology world, if that distinction is not a false one and can be usefully made. i think it important for those of us split between two cultures to ensure that we fall to one side and not the other, in particular that we do not fall into the oftentimes loutish and ultimately unproductive communication mores exhibited by many of the online technical forums. whenever my wife and i hear a news story on tv or radio openly wondering why more women do not go into i.t., i blurt out something like: "you wanna know why? just go read the comments section of most posts at slashdot.com. why on earth would anyone who didn't have to put up with that kind of culture actually choose to put up with it?" isn't "india does not exist" exactly the kind of response one would find on slashdot.com if the initial question was, "i want to go to india -how best to get there?"? with all this in mind, i hereby issue my own question, this time a technical one: information technology and libraries | june 2013 6 "i want to programmatically convert a largish set of documents from pdf to docx format. how best to do it?" i hope you don't think i'm an idiot. editorial board thoughts: requiring and demonstrating technical skills for library employment emily morton-owens information technologies and libraries | september 2016 6 recently i’ve been involved in a number of conversations about technical skills for library jobs, sparked by an ital article by monica maceli1 and a code4lib presentation by jennie rose halperin.2 maceli performed a text analysis of job postings on code4lib to reveal what skills are cooccurring and most frequent. halperin problematized the expense of the mls credential in comparison to the qualifications actually required by library technology jobs and the salaries offered for technical versus nontechnical work. this work has inspired many conversations about the shift in skills required for library work, the value placed on different kinds of labor, and how mls programs can teach library technology. during a period of hiring at my institution and through teaching a library school course in which many of the students are on the brink of graduation, my attention has been called particularly to one point in the library employment process: job postings. these advertisements are the first step in matching aspiring library staff with the real-life needs of libraries—where the rubber meets the road between employer expectations and new-grad experience. most libraries already use the practice of distinguishing between required and preferred qualifications, which is a good start, especially for technology jobs where candidates may offer strong learning proficiency yet lack a few particular tools. although there have been conflicting interpretations of the hewlett-packard research suggesting that men are more likely than women to apply to jobs when they don’t meet all the requirements,3 i observe a general tendency among graduating students to err on the side of caution because they’re not sure which qualifications they can claim. among my students, for example, constant confusion attends the years of experience required. is this library experience? general job experience? experience at the same type of library? paid or unpaid? postings are often ambiguous and students may choose to apply or not. similarly, there are questions about what extent of experience qualifies someone to know a technology: mastering it through creating new projects at a paid job, experience maintaining it, or merely basic familiarity? not knowing who has been hired, and on the basis of what kind of experience, is a gap for researchers trying to close the loop on job advertisements. even when a job posting has avoided an overlong list of required technical skills, it might still be expressing a narrow sense of what’s required to qualify. someone who understands subversion will be capable of understanding git, so we see plenty of job advertisements that ask for experience with a “a version control system (e.g. git, subversion, or mercurial).” i recently polled staff in our department and found very few of us with bachelor’s degrees in technical subjects. more of us had come to working in library technology through work experience or graduate programs. and yet, our job postings contained long statements that conflated education and experience, such as “bachelor’s degree in computer science, information science, or other emily morton-owens (egmowens@upenn.edu), a member of the ital editorial board, is director of digital library development and systems, university of pennsylvania libraries, philadelphia, pennsylvania. mailto:egmowens@upenn.edu editorial board thoughts | morton-owens doi: 10.6017/ital.v35i3.9527 7 relevant field and at least 3 years of experience application development in object oriented and scripting languages or equivalent combination of education and experience. master’s desirable.” i edited our statement to more clearly allow a combination of factors that would show sufficient preparation: “bachelor’s degree and a minimum of 3-5 years of experience, or an equivalent combination of education and experience, are required; a master’s degree is preferred,” followed by a separate description of technical skills needed. this increased the number and quality of our applications, so i’ll remain on the lookout for opportunities to represent what we want to require more faithfully and with an open mind. meanwhile, on the other side of the table, students and recent grads are uncertain how to demonstrate their skills. first, they’re wondering how to show clearly enough that they meet requirements like “three years of work experience” or “experience with user testing” so that their application is seriously considered. second, they ask about possibilities to formalize skills. recently, i’ve gotten questions about a certificate program in ux and whether there is any formal certification to be a systems librarian. surveying the past experience of my own network—with very diverse paths into technology jobs ranging from undergraduate or second master’s degrees to learning scripting as a technical services librarian to pre-mls work experience—doesn’t suggest any standard method for substantiating technical knowledge. once again, the truth of the situation may be that libraries will welcome a broad range of possible experience, but the postings don’t necessarily signal that. some advice from the tech industry about how to be more inviting to candidates applies to libraries too; for example, avoiding “rockstar”/ “ninja” descriptions, emphasizing the problem space over years of experience,4 and designing interview processes that encourage discussion rather than “gotcha” technical tasks. at penn libraries, for example, we’ve been asking developer candidates to spend a few hours at most on a take-home coding assignment, rather than doing whiteboard coding on the spot. this gives us concrete code to discuss in a far more realistic and relaxed context. while it may be helpful to express requirements better to encourage applicants to see more clearly whether they should respond to a posting, this is a small part of the question of preparing new mls grads for library technology jobs. the new grads who are seeking guidance on substantiating their skills are the ones who are confident they possess them. others have a sense that they should increase their comfort with technology but are not sure how to do it, especially when they’ve just completed a whole new degree and may not have the time or resources to pursue additional training. even if we make efforts to narrow the gap between employers and jobseekers, much remains to be discussed regarding the challenge of readying students with different interests and preparation for library employment. library school provides a relatively brief window to instill in students the fundamentals and values of the profession and it can’t be repurposed as a coding academy. there persists a need to discuss how to help students interested in technology learn and demonstrate competencies rather than teaching them rapidly shifting specific technologies. editorial board thoughts | morton-owens doi: 10.6017/ital.v35i3.9527 8

farnel information technologies and libraries | december 2016 3 the core metadata team at my institution is small but effective. in addition to myself as coordinator, we include two librarians and two full-time metadata assistants. our metadata assistant positions are considered to be similar, in some ways, to other senior assistant positions within the organization which require or at least prefer that individuals have a library technician diploma. however, neither of our metadata assistants has such a diploma. their credentials, in fact, are quite different. in part, this difference is driven by the nature of the work that our metadata assistants do. they work regularly with different metadata standards such as mods, dc, ddi in addition to marc. the perform operations on large batches of metadata using languages such as xslt or r. this is quite different in many ways than the work of their colleagues who work with the ils, many of whom do have a library technician diploma. as we prepare for an upcoming short-term leave of one of our team members, i have been thinking a great deal about the work our metadata assistants do and whether or not we would find an individual who came through a librarian technician program who had the skills and knowledge we need a replacement to have. and i have also been reminded of conversations i have had with recently graduated library technicians who felt their exposure to metadata standards, practices, and tools beyond rda and marc had been lacking in their programs. this got me thinking about the presence or absence of metadata courses in library technician programs in canada. i reached out to two colleagues from macewan university—norene erickson and lisa shamchuk—who are doing in-depth research into library technician education in canada. they kindly provided me with a list of canadian institutions that offer a library technician program so i could investigate further. now, i must begin with two caveats. one, this is very much a surface level scan rather than an indepth examination, although this is simply the first step in what i hope will be a longer term investigation. second, although several francophone institutions in canada offer library technician programs, i did not review their programs; i was concerned that my lack of fluency in the french language could lead to inadvertent misrepresentations.

saskatchewan polytechnic (http://saskpolytech.ca/programs-andcourses/programs/library-and-information-technology.aspx) my method was quite simple. using the program websites listed above, i reviewed the course listings looking for ‘metadata’ either in the title or in the description when it was available. of the fourteen (14) programs examined, nine (9) had no course with metadata in the title or description. two (2) programs had courses where metadata was listed as part of the content but not the focus: langara college as part of “special topics: creating and managing digital collections” and seneca college as part of “cataloguing iii” which has a partial focus on metadata for digital collections. three (3) of the programs had a course with metadata in the title or description; all are a variation on “introduction to metadata and metadata applications”. (importantly, the three institutions in question conestoga college, confederation college, and mohawk college are all connected and share courses online). so, what do these very preliminary and impressionistic findings tell us? it seems that there is little opportunity for students enrolled in library technician programs in canada to be exposed to the metadata standards, practices, and tools that are increasingly necessary for positions involved in work with digital collections, research data management, digital preservation, and the like. admittedly, no program can include courses on all potentially relevant topics. in addition, formal course work is only one aspect of training and education that can prepare graduates for their career; practica and work placements and other more informal activities during a program are crucial, as are the skills and knowledge that can only be developed once hired and on the job. nevertheless, based on the investigation above, one would be justified in asking if we are disadvantaging students by not working to incorporate additional coursework focused on metadata standards, application, and tools, as well as on basic skills in manipulation of metadata in large batches. scripting languages or equivalent combination of education and experience. master’s desirable.” i edited our statement to more clearly allow a combination of factors that would show sufficient preparation: “bachelor’s degree and a minimum of 3-5 years of experience, or an equivalent combination of education and experience, are required; a master’s degree is preferred,” followed by a separate description of technical skills needed. this increased the number and quality of our editorial board thoughts | farnel https://doi.org/10.6017/ital.v35i4.9601 6 applications, so i’ll remain on the lookout for opportunities to represent what we want to require more faithfully and with an open mind. meanwhile, on the other side of the table, students and recent grads are uncertain how to demonstrate their skills. first, they’re wondering how to show clearly enough that they meet requirements like “three years of work experience” or “experience with user testing” so that their application is seriously considered. second, they ask about possibilities to formalize skills. recently, i’ve gotten questions about a certificate program in ux and whether there is any formal certification to be a systems librarian. surveying the past experience of my own network—with very diverse paths into technology jobs ranging from undergraduate or second master’s degrees to learning scripting as a technical services librarian to pre-mls work experience—doesn’t suggest any standard method for substantiating technical knowledge. once again, the truth of the situation may be that libraries will welcome a broad range of possible experience, but the postings don’t necessarily signal that. some advice from the tech industry about how to be more inviting to candidates applies to libraries too; for example, avoiding “rockstar”/ “ninja” descriptions, emphasizing the problem space over years of experience,1 and designing interview processes that encourage discussion rather than “gotcha” technical tasks. at penn libraries, for example, we’ve been asking developer candidates to spend a few hours at most on a take-home coding assignment, rather than doing whiteboard coding on the spot. this gives us concrete code to discuss in a far more realistic and relaxed context. while it may be helpful to express requirements better to encourage applicants to see more clearly whether they should respond to a posting, this is a small part of the question of preparing new mls grads for library technology jobs. the new grads who are seeking guidance on substantiating their skills are the ones who are confident they possess them. others have a sense that they should increase their comfort with technology but are not sure how to do it, especially when they’ve just completed a whole new degree and may not have the time or resources to pursue additional training. even if we make efforts to narrow the gap between employers and jobseekers, much remains to be discussed regarding the challenge of readying students with different interests and preparation for library employment. library school provides a relatively brief window to instill in students the fundamentals and values of the profession and it can’t be repurposed as a coding academy. there persists a need to discuss how to help students interested in technology learn and demonstrate competencies rather than teaching them rapidly shifting specific technologies. references 1. erin kissane, “job listings that don’t alienate,”

information for digital libraries j. m. morales-del-castillo, r. pedraza-jiménez, a. a. ruíz, e. peis, and e. herrera-viedma in this paper we present the theoretical and methodological foundations for the development of a multi-agent selective dissemination of information (sdi) service model that applies semantic web technologies for specialized digital libraries. these technologies make possible achieving more efficient information management, improving agent–user communication processes, and facilitating accurate access to relevant resources. other tools used are fuzzy linguistic modelling techniques (which make possible easing the interaction between users and system) and natural language processing (nlp) techniques for semiautomatic thesaurus generation. also, rss feeds are used as “current awareness bulletins” to generate personalized bibliographic alerts. n owadays, one of the main challenges faced by information systems at libraries or on the web is to efficiently manage the large number of documents they hold. information systems make it easier to give users access to relevant resources that satisfy their information needs, but a problem emerges when the user has a high degree of specialization and requires very specific resources, as in the case of researchers.1 in “traditional” physical libraries, several procedures have been proposed to try to mitigate this issue, including the selective dissemination of information (sdi) service model that make it possible to offer users potentially interesting documents by accessing users’ personal profiles kept by the library. nevertheless, the progressive incorporation of new information and communication technologies (icts) to information services, the widespread use of the internet, and the diversification of resources that can be accessed through the web has led libraries through a process of reinvention and transformation to become “digital” libraries.2 this reengineering process requires a deep revision of work techniques and methods so librarians can adapt to the new work environment and improve the services provided. in this paper we present a recommendation and sdi model, implemented as a service of a specialized digital library (in this case, specialized in library and information science), that can increase the accuracy of accessing information and the satisfaction of users’ information needs on the web. this model is built on a multi-agent framework, similar to the one proposed by herrera-viedma, peis, and morales-del-castillo,3 that applies semantic web technologies within the specific domain of specialized digital libraries in order to achieve more efficient information management (by semantically enriching different elements of the system) and improved agent–agent and user–agent communication processes. furthermore, the model uses fuzzy linguistic modelling techniques to facilitate the user–system interaction and to allow a higher grade of automation in certain procedures. to increase improved automation, some natural language processing (nlp) techniques are used to create a system thesaurus and other auxiliary tools for the definition of formal representations of information resources. in the next section, “instrumental basis,” we briefly analyze sdi services and several techniques involved in the semantic web project, and we describe the preliminary methodological and instrumental bases that we used for developing the model, such as fuzzy linguistic modelling techniques and tools for nlp. in “semantic sdi service model for digital libraries,” the bulk of this work, the application model that we propose is presented. finally, to sum up, some conclusive data are highlighted. n instrumental basis filtering techniques for sdi services filtering and recommendation services are based on the application of different process-management techniques that are oriented toward providing the user exactly the information that meets his or her needs or can be of his or her interest. in textual domains, these services are usually developed using multi-agent systems, whose main aims are n to evaluate and filter resources normally represented in xml or html format; and n to assist people in the process of searching for and retrieving resources.4 j. m. morales-del-castillo (josemdc@ugr.es) is assistant professor of information

either content-based recommendation systems or collaborative recommendation systems.5 content-based recommendation systems filter information and generate recommendations by comparing a set of keywords defined by the user with the terms used to represent the content of documents, ignoring any information given by other users. by contrast, collaborative filtering systems use the information provided by several users to recommend documents to a given user, ignoring the representation of a document’s content. it is common to group users into different categories or stereotypes that are characterized by a series of rules and preferences, defined by default, that represent the information needs and common behavioural habits of a group of related users. the current trend is to develop hybrids that make the most of content-based and collaborative recommendation systems. in the field of libraries, these services usually adopt the form of sdi services that, depending on the profile of subscribed users, periodically (or when required by the user) generate a series of information alerts that describe the resources in the library that fit a user’s interests.6 sdi services have been studied in different research areas, such as the multi-agent systems development domain,7 and, of course, the digital libraries domain.8 presently, many sdi services are implemented on web platforms based on a multi-agent architecture where there is a set of intermediate agents that compare users’ profiles with the documents, and there are input-output agents that deal with subscriptions to the service and display generated alerts to users.9 usually, the information is structured according to a certain data model, and users’ profiles are defined using a series of keywords that are compared to descriptors or the full text of the documents. despite their usefulness, these services have some deficiencies: n the communication processes between agents, and between agents and users, are hindered by the different ways in which information is represented. n this heterogeneity in the representation of information makes it impossible to reuse such information in other processes or applications. a possible solution to these deficiencies consists of enriching the information representation using a common vocabulary and data model that are understandable by humans as well as by software agents. the semantic web project takes this idea and provides the means to develop a universal platform for the exchange of information.10 semantic web technologies the semantic web project tries to extend the model of the present web by using a series of standard languages that enable enriching the description of web resources and make them semantically accessible.11 to do that, the project basis itself on two fundamental ideas: (1) resources should be tagged semantically so that information can be understood both by humans and computers, and (2) intelligent agents should be developed that are capable of operating at a semantic level with those resources and that infer new knowledge from them (shifting from the search of keywords in a text to the retrieval of concepts).12 the semantic backbone of the project is the resource description framework (rdf) vocabulary, which provides a data model to represent, exchange, link, add, and reuse structured metadata of distributed information sources, thereby making them directly understandable by software agents.13 rdf structures the information into individual assertions (e.g., “resource,” “property,” and “property value triples”) and uniquely characterizes resources by means of uniform resource identifiers (uris), allowing agents to make inferences about them using web ontologies or other, simpler semantic structures, such as conceptual schemes or thesauri.14 even though the adoption of the semantic web and its application to systems like digital libraries is not free from trouble (because of the nature of the technologies involved in the project and because of the project’s ambitious objectives,15 among other reasons), the way these technologies represent the information is a significant improvement over the quality of the resources retrieved by search engines, and it also allows the preservation of platform independence, thus favouring the exchange and reuse of contents.16 as we can see, the semantic web works with information written in natural language that is structured in a way that can be interpreted by machines. for this reason, it is usually difficult to deal with problems that require operating with linguistic information that has a certain degree of uncertainty (e.g., when quantifying the user’s satisfaction in relation to a product or service). a possible solution could be the use of fuzzy linguistic modelling techniques as a tool for improving system–user communication. fuzzy linguistic modelling fuzzy linguistic modelling supplies a set of approximate techniques appropriate for dealing with qualitative aspects of problems.17 the ordinal linguistic approach is defined according to a finite set of tags (s) completely ordered and with odd cardinality (seven or nine tags): { }{ }t,=hi,s=s i …∈ 0, the central term has a value of approximately 0.5, and the rest of the terms are arranged symmetrically around a semantic model of selective dissemination of information | morales-del-castillo et al. 23 it. the semantics of each linguistic term is given by the ordered structure of the set of terms, considering that each linguistic term of the pair (si, st-i) is equally informative. each label si is assigned a fuzzy value defined in the interval [0,1] that is described by a linear trapezoidal property function represented by the 4-tupla (ai, bi, αi, βi). (the two first parameters show the interval where the property value is 1.0; the third and fourth parameters show the left and right limits of the distribution.) additionally, we need to define the following properties: 1.–the set is ordered: si ≥ sj if i ≥ j. 2.–there is the negation operator: neg(si ) = sj, with j = t i. 3.–maximization operator: max(si, sj) = si if si ≥ sj. 4.–minimization operator: min(si, sj) = si if si ≤ sj. it also is necessary to define aggregation operators, such as linguistic weighted averaging (lwa),18 capable of and operating with and combining linguistic information. focusing on facilitating the interaction between users and system, the other starting objective is to achieve the development and implementation of the model proposed in the most automated way possible. to do this, we use a basic auxiliary tool—a thesaurus—that, among other tasks, assists users in the creation of their profile and enables automating the alerts generation. that is why it is critical to define the way in which we create this tool, and in this work we propose a specific method for the semiautomatic development of thesauri using nlp techniques. nlp techniques and other automating tools nlp consists of a series of linguistic techniques, statistic approaches, and machine learning algorithms (mainly clustering techniques) that can be used, for example, to summarize texts in an automatic way, to develop automatic translators, and to create voice recognition software. another possible application of nlp would be the semiautomatic construction of thesauri using different techniques. one of them consists of determining the lexical relations between the terms of a text (mainly synonymy, hyponymy, and hyperonymy),19 and extracting terms that are more representative for the text’s specific domain.20 it is possible to elicit these relations by using linguistic tools, like princeton’s wordnet (http://wordnet .princeton.edu) and clustering techniques. wordnet is a powerful multilanguage lexical database where each one of its entries is defined, among other elements, by their synonyms (synsets), hyponyms, and hyperonyms.21 as a consequence, once given the most important terms of a domain, wordnet can be used to create from them a thesaurus (after leaving out all terms that have not been identified as belonging or related to the domain of interest).22 this tool can also be used with clustering techniques—for example, to group documents of a collection in a set of nodes or clusters, depending on their similarity. each of these clusters is described by the most representative terms of their documents. these terms make up the most specific level of a thesaurus and are used to search in wordnet for their synonyms and most general terms, contributing (with the repetition of this procedure) to the bottom-up-development process of the thesaurus.23 although there are many others, these are some of the most well-known techniques of semiautomatic thesaurus generation (semiautomatic because, needless to say, the supervision of experts is necessary to determine the validity of the final result). for specialized digital libraries, we propose developing, on a multi-agent platform and using all these tools, sdi services capable of generating alerts and recommendations for users according to their personal profiles. in particular, the model presented here is the result of several previous models merging, and its service is based on the definition of “current-awareness bulletins,” where users can find a basic description of the resources recently acquired by the library or those that might be of interest to them.24 n the semantic sdi service model for digital libraries the sdi service includes two agents (an interface agent and a task agent) distributed in a four-level hierarchical architecture: user level, interface level, task level and resource level. its main components are a repository of full-text documents (which make up the stock of the digital library) and a series of elements described using different rdfbased vocabularies: one or several rss feeds that play a role similar to that of current-awareness bulletins in traditional libraries; a repository of recommendation log files that store the recommendations made by users about the resources, and a thesaurus that lists and hierarchically relates the most relevant terms of the specialization domain of the library.25 also, the semantics of each element (that is, its characteristics and the relations the element establishes with other elements in the system) are defined in a web ontology developed in web ontology language (owl).26 next, we describe these main elements as well as the different functional modules that the system uses to carry out its activity. elements of the model there are four basic elements that make up the system: 24 information technology and libraries | march 2009 the thesaurus, user profiles, rss feeds, and recommendation log files. thesaurus an essential element of this sdi service is the thesaurus, an extensible tool used in traditional libraries that enables organizing the most relevant concepts in a specific domain, defining the semantic relations established between them, such as equivalence, hierarchical, and associative relations. the functions defined for the thesaurus in our system include helping in the indexing of rss feeds items and in the generation of information alerts and recommendations. to create the thesaurus, we followed the method suggested by pedraza-jiménez, valverde-albacete, and navia-vázquez.27 the learning technique used for the creation of a thesaurus includes four phases: preprocessing of documents, parameterizing the selected terms, conceptualizing their lexical stems, and generating a lattice or graph that shows the relation between the identified concepts. essentially, the aim of the preprocessing phase is to prepare the documents’ parameterization by removing elements regarded as superfluous. we have developed this phase in three stages: eliminating tags (stripping), standardizing, and stemming. in the first stage, all the tags (html, xml, etc.) that can appear in the collection of documents are eliminated. the second stage is the standardization of the words in the documents in order to facilitate and improve the parameterization process. at this stage, the acronyms and n-grams (bigrams and trigrams) that appear in the documents are identified using lists that were created for that purpose. once we have detected the acronyms and n-grams, the rest of the text is standardized. dates and numerical quantities are standardized, being substituted with a script that identifies them. all the terms (except acronyms) are changed to small letters, and punctuation marks are removed. finally, a list of function words is used to eliminate from the texts articles, determiners, auxiliary verbs, conjunctions, prepositions, pronouns, interjections, contractions, and grade adverbs. all the terms are stemmed to facilitate the search of the final terms and to improve their calculation during parameterization. to carry out this task, we have used morphy, the stemming algorithm used by wordnet. this algorithm implements a group of functions that check whether a term is an exception that does not need to be stemmed and then convert words that are not exceptions to their basic lexical form. those terms that appear in the documents but are not identified by morphy are eliminated from our experiment. the parameterization phase has a minimum complexity. once identified, the final terms (roots or bases) are quantified by being assigned a weight. such weight is obtained by the application of the scheme term frequencyinverse document frequency (tf-idf), a statistic measure that makes possible the quantification of the importance of a term or n-gram in a document depending on its frequency of appearance and in the collection the document belongs to. finally, once the documents have been parameterized, the associated meanings of each term (lemma) are extracted by searching for them in wordnet (specifically, we use wordnet 2.1 for unix-like systems). thus we get the group of synsets associated with each word. the group of hyperonyms and hyponyms also are extracted from the vocabulary of the analyzed collection of documents. the generation of our thesaurus—that is, the identification of descriptors that better represent the content of documents, and the identification of the underlying relations between them—is achieved using formal concept analysis techniques. this categorization technique uses the theory of lattices and ordered sets to find abstraction relations from the groups it generates. furthermore, this technique enables clustering the documents depending on the terms (and synonyms) it contains. also, a lattice graph is generated according to the underlying relations between the terms of the collection, taking into account the hyperonyms and hyponyms extracted. in that graph, each node represents a descriptor (namely, a group of synonym terms) and clusters the set of documents that contain it, linking them to those with which it has any relation (of hyponymy or hyperonymy). once the thesaurus is obtained by identifying its terms and the underlying relations between them, it is automatically represented using the simple knowledge organization system (skos) vocabulary (see figure 1).28 user profiles user profiles can be defined as structured representations that contain personal data, interests, and preferences of users with which agents can operate to customize the sdi service. in the model proposed here, these profiles are basically defined with friend of a friend (foaf), a specific rdf/xml for describing people (which favours the profile interoperability, since this is a widespread vocabulary supported by an owl ontology) and another nonstandard vocabulary of our own to define fields not included in foaf (see figure 2).29 profiles are generated the moment the user is registered in the system, and they are structured in two parts: a public profile that includes data related to the user’s identity and affiliation, and a private profile that includes the user’s interests and preferences about the topic of the alerts he or she wishes to receive. to define their preferences, users must specify keywords and concepts that best define their information a semantic model of selective dissemination of information | morales-del-castillo et al. 25 needs. later, the system compares those concepts with the terms in the thesaurus using as a similarity measure the edit tree algorithm.30 this function matches character strings, then returns the term introduced (if there’s an exact match) or the lexically most similar term (if not). consequently, if the suggested term satisfies user expectations, it will be added to the user’s profile together with its synonyms (if any). in those cases where the suggested term is not satisfactory, the system must have any tool or application that enables users to browse the thesaurus and select terms that better describe their needs. an example of this type of applications is thmanager (http://thmanager .sourceforge.net), a project of the universidad de zaragoza, spain, that enables editing, visualizing, and going through structures defined in skos. each of the terms selected by the user to define his or her areas of interest has an associated linguistic frequency value (tagged as <freq>) that we call “satisfaction frequency.” it represents the regularity with which a particular preference value has been used in alerts positively evaluated by the user. this frequency measures the relative importance of the preferences stated by the user and allows the interface agent to generate a ranking list of results. the range of possible values for these frequencies is defined by a group of seven labels that we get from the fuzzy linguistic variable “frequency,” whose expression domain is defined by the linguistic term set s = {always, almost_ always, often, occasionally, rarely, almost_never, never}, being the default value and “occasionally” being the central value. rss feeds thanks to the popularization of blogs, there has been widespread use of several vocabularies specifically designed for the syndication of contents (that is, for making accessible to other internet users the content of a website by means of hyperlink lists called “feeds”). to create our current-awareness bulletin we use rss 1.0, a vocabulary that enables managing hyperlinks lists in an easy and flexible way. it utilizes the rdf/xml syntax and data model and is easily extensible because of the use of <skos:concept rdf:about=”7”> <skos:inscheme rdf:resource=”http://www.ugr.es/…/thes/”/> <skos:preflabel xml:lang=”es”>proceedings</skos:preflabel>

modules that enable extending the vocabulary without modifying its core each time new describing elements are added. in this model several modules are used: the dublin core (dc) module to define the basic bibliographic information of the items utilizing the elements established by the dublin core metadata initiative (http:// dublincore.org); the syndication module to facilitate software agents synchronizing and updating rss feeds; and the taxonomy module to assign topics to feeds items. the structure of the feeds comprises two areas: one where the channel itself is described by a series of basic metadata like a title, a brief description of the content, and the updating frequency; and another where the descriptions of the items that make up the feed (see figure 3) are defined (including elements such as title, author, summary, hyperlink to the primary resource, date of creation, and subjects). recommendation log file each document in the repository has an associated recommendation log file in rdf that includes the listing of evaluations assigned to that resource by different users since the resource was added to the system. each of the entries of the recommendation log files consists of a recommendation value, a uri that identifies the user that has done the recommendation, and the date of the record (see figure 4). the expression domain of the recommendations is defined by the following set of five fuzzy linguistic labels that are extracted from the linguistic variable “quality of the resource”: q = {very_low, low, medium, high, very_high}. these elements represent the raw materials for the sdi service that enable it to develop its activity through four processes or functional modules: the profiles updating process, rss feeds generation process, alert generation process, and collaborative recommendation process. system processes profiles updating process since the sdi service’s functions are based on generating passive searches to rss feeds from the

item sample in a user’s profile, updating the profiles becomes a critical task. user profiles are meant to store long-term preferences, but the system must be able to detect any subtle change in these preferences over time to offer accurate recommendations. in our model, user profiles are updated using a simple mechanism that enables finding users’ implicit preferences by applying fuzzy linguistic techniques and taking into account the feedback users provide. users are asked about their satisfaction degree (ej) in relation to the information alert generated by the system (i.e., whether the items a semantic model of selective dissemination of information | morales-del-castillo et al. 27 retrieved are interesting or not). this satisfaction degree is obtained from the linguistic variable “satisfaction,” whose expression domain is the set of five linguistic labels: s’ = {total, very_high, high, medium, low, very_low, null}. this mechanism updates the satisfaction frequency associated with each user preference according to the satisfaction degree ej. it requires the use of a matching function similar to those used to model threshold weights in weighted search queries.31 the function proposed here rewards the frequencies associated with the preference values present when resources assessed are satisfactory, and it penalizes them when this assessment is negative. let ej { }t,=hba,|ss,s ba 0,...∈∈ s’ be the degree of satisfaction, and f j i l { }t,=hba,|ss,s ba 0,...∈∈ s the frequency of property i (in this case i = “preference”) with value l, then we define the

the mechanism becomes, since it will be easier for the sdi service to “learn” which documents are likely more interesting to the user according to his or her preferences. this evaluation process is not only useful for updating users’ profiles: as we will see in the next section, the feedback provided by the users can be reused to define a recommendation system that benefits from the their experience, knowledge, and critical skills. rss feeds generation and updating process in this module, the rss feeds of the digital library (one or several feeds, depending on the library’s specific needs) are created and updated semiautomatically (see figure 5). therefore the system administrator must play an active role in the process, defining through a simple input interface the different elements needed to describe each rss feed and their corresponding items. this task can be simplified if the administrator is able to complete the description of both feeds and items that use any application capable of extracting metadata from resources in databases or online repositories. in this specific case, we have chosen to use digidocmeta, a tool designed by the pompeu fabra university’s digidoc laboratory (www.metaeditor.net) that analyzes the content of resources and subsequently supplies the administrator with descriptive data (such as title, summary, keywords, and language) extracted automatically from them. administrators can check those data through an easy and clear interface, and, if necessary, they can use different edition tools to modify them. however, in both cases, the system administrator must supervise the assignment of topics describing the content of the resource. to facilitate this task, we also use a tool that helps in the process of assigning topics to items. it works in a similar way to the preferences selection process (as described earlier): the administrator suggests a series of topics that are lexically matched to the terms of the thesaurus using the tree edit algorithm. the terms that exactly match the terms of the thesaurus will be assigned as a topic (together with their synonyms). if there’s no match, the system will suggest a series of lexically similar terms that the administrator can use or not, depending on his or her own opinion. alert generation or information push process this module can be considered the backbone of the sdi service (see figure 6). it consists of triggering against the rss feed a passive search query (i.e., on behalf of the user) about the areas of interest defined in his or her profile. consequently, the customized information alert generated by the system will be displayed without an explicit request from the user (this is known as “push,” or passive reception of information). this process consists of four steps: 1. users access the system by giving their username and password. 2. the task agent compares the areas of interest in the active user’s profile with the descriptors that characterize the content of the n items of the rss feed. the agent distinguishes terms that better meet the specific information needs of the user. in this case, instead of using traditional lexical matching (where two character strings are compared), we propose using a semantic similarity measure and harnessing the thesaurus as a tool for organizing knowledge. to do so, we use a function, defined by oldakowsky and byzer, that enables calculating the similarity between rdf objects.32 this function makes it possible to determine the distance between two terms in a concept schema according to their situation within the conceptual hierarchy (in our model, this concept schema is the thesaurus of the system). 3. the task agent presents to the user those resources whose similarity matches or exceeds a predefined threshold, k (k being a value close to 1), discarding any document that does not reach it. 4. the interface agent generates an alert in the homepage of the website that notifies the user of the existence of new documents that can be of interest to him or her. this alert links directly to the list generated by the task agent, from which the { } { } ( )

is more than one rss feed in the library, the retrieved items from each feed must be aggregated into a single list of results. if no relevant items are found, the user will be notified. collaborative recommendation process this system can also offer additional information about the recommended resources, regardless of the similarity between content descriptors and users’ preferences. this can be achieved by defining an auxiliary collaborative recommendation system that is based on the opinions of users in the library with a profile similar to that of the active user. therefore, taking as a starting point the list of recommended resources, the task agent retrieves the associated recommendation log file of each item and extracts both the identifier of all the users that have ever recommended that specific resource, and the corresponding assessment given by each one of them (we have to keep in mind that these assessments are based on the satisfaction degree stated by the user in the profile updating process). the next step is comparing the profile of each user with the active user’s profile in a way similar to the process of information push (but matching preferences instead of topics and preferences this time). in other words, the task agent proceeds to define a cluster of similar users. finally, the task agent aggregates the different assessments using the fuzzy linguistic operator lwa,33 which returns as output a new linguistic tag that gives users new criteria to select resources of interest. n conclusions and future works libraries are moving services (like sdi) to the web. combining semantic web technologies with nlp techniques and fuzzy linguistic techniques favours the development of improved sdi services that are capable of offering accurate information according to users’ needs. the semantic web has a common data model and syntax that guarantee the interoperability of resources (independently of the platform), thus making easier the establishment of exchange and collaborative networks between digital libraries. furthermore, these technologies make it possible to considerably improve the communication processes between agents and between users and agents. because nlp techniques and formal concept analysis enable detecting descriptors and, in combination with other lexical resources, identifying the semantic relations among them (synonymy, hyponymy and hyperonymy relations in particular), they facilitate the semiautomatic generation of thesauri. these thesauri can later be used as tools for the semiautomatic indexation of resources and to generate alerts and recommendations. however, those tasks require of the attentive supervision of a system administrator, who is responsible for deciding whether the suggested subjects or keywords are appropriate. figure 6. alert generation processfigure 5. profiles and rss feeds generation process a semantic model of selective dissemination of information | morales-del-castillo et al. 29 on the other hand, the use of auxiliary tools such as metadata extractors makes possible the formalization of resource descriptions that will be later spread through rss feeds, as well as the modification of the suggested descriptions and the inclusion of additional information to those descriptions. a future line of research should be focused on the development of an integrated application that makes possible the semiautomatic generation of thesauri by following the methods described in this work. this way, each information center or library would have the capability of generating its own specialized and domain-dependant thesaurus. it would be done starting from the full-text electronic documents available in the library, as well as any other collection of documents or specialized digital information sources, such as websites, specialized dictionaries, and so on. n acknowledgement this work has been supported by the research projects tin2007-61079

machine readable records recon working task force: henriette d. avram, chairman; richard de gennaro; josephine s. pulsifer; john c. rather; joseph a. rosenthal and allen b. veaner. this study of the feasibility of determining levels or subsets of the established marc ii format concludes that only two levels are necessary and desirable for national purposes: 1) the full ma.rc ii format for distribution purposes; and 2) a less complex subset to be used by libraries reporting holdings to the national union catalog. introduction in march 1969, the advisory committee to the recon working task force, after approving publication of the initial recon report ( 1 ), endorsed investigation of a number of questions raised in that report as well as consideration of certain issues not covered in the initial survey. the basic tasks to be undertaken have been described in another article in this issue (2). with further support for recon from the council on library resources, inc., the working task force has met several times to explore some of these problems. this article reports the conclusions reached with respect to one task: the feasibility of determining a level or subset of the established marc ii format that would still allow a library using it to be part of a future national network. definition of "level" during the initial recon study the working task force, for discussion purposes, considered levels of encoding detail of machine readable catalog records in relation to the conditions under which conversion might occur. a level was distinguished by differences in 1) the bibliographic \ levels of machine readable recordsjrecon task force 123 completeness of a record, and 2) the extent to which its contents were separately designated. with respect to the latter point, the recon report stated: "a machine format for recording of bibliographic data and the identification of these data for machine manipulation is composed of a basic structure (physical representation), content designators (tags, delimiters, subfield codes), and contents (data elements in fixed and variable fields). although the basic structure should remain constant, the contents and their designation are subject to variation. for example, a name entry could be designated merely as a name instead of being distinguished as a personal name or corporate name. when a distinction is made, a personal name entry can be further refined as a single surname, multiple surname, or forename. likewise, if a personal name entry contains date of birth and/ or death, relationship to the work (editor, compiler, etc.), or title, these data elements can be identified or can be treated as part of the name entry without any unique identification. thus individual data elements can be identified at various levels of completeness." (3) appendix f of the recon report tentatively defined three levels: "level 1 involves the encoding of bibliographic items according to the practices followed at the library of congress for currently cataloged items, i.e., the marc ii format. a distinguishing feature of level 1 is the inclusion of certain content designators and data elements which, in some instances, can be specified only with the physical item in hand. "level 2 supplies the same degree of detail as in level 1 insofar as it can be ascertained through an already supplied bibliographic record ... . "level 3 would be distinguished by the fact that only part of the bibliographic data in the original catalog record would be transcribed. in addition, content designators might be restricted ... " ( 4) . at the outset of the present study, however, it was recognized that incomplete bibliographic description is not acceptable in records for national use. in addition, it seemed that the question of having a level below level 2 really arose from a desire to define a machine readable record with a lesser degree of content designation rather than one with less complete bibliographic data. it was decided, therefore, to concentrate the study effort on this task, and the original formulation of level 3 was discarded. on further consideration, it was realized also that the distinguishing feature between levels 1 and 2 was not significant. omission of data elements that cannot be determined unless the book is in hand may simplify an individual record but does not simplify the content designators in the format because these elements are often present in other 124 journal of library automation vol. 3/2 june, 1970 records. thus, as far as content designation is concerned, levels 1 and 2 (as originally defined) were in fact the same. once this similarity became apparent, it was recognized that the specification of levels really depended on the functions of machine readable catalog records from the standpoint of national use. functions and levels on the basis of present knowledge, it seems that machine readable records will serve two primary functions for national use. the first involves the distribution of cataloging information in machine readable form for use by library networks, library systems, and individual libraries; the second involves the recording of bibliographic data in a national union catalog to reflect the holdings of libraries in the united states and canada. in this report, the first is called the distribution function; the second is called the national union catalog ( nuc) function. each of these functions can be related to a distinct level of machine readable record. the distribution function the distribution function can best be satisfied by a detailed record in a communications format from which an individual library can extract the subset of data useful in its application. at the present stage of library automation, it is impossible to define rigorously all of the potential uses of machine readable catalog records. thus, there is no way to predict which data elements may not be needed or to rank them according to their value to a wide variety of users under different circumstances. to confirm the wide variation in treatment of the marc ii format, an analysis was made of the use of marc content designators by eight table 1. use of marc content designators by 8 library systems or networks number of libraries number of items fixed fields (19) tags indicators (63) 8 26 7 6 6 3 5 1 5 4 6 3 3 7 2

library systems and emerging networks. the data from this analysis were synthesized for presentation in two tables. table 1 shows the acceptance of content designators in terms of the absolute number of libraries using them. it should be read as shown by the following examples: 1) 26 of the 63 marc tags are used by all eight libraries; 2) 92 of the 126 indicators are used by only three libraries. table 2 shows the acceptance of content designators in relative terms. thus, if only three libraries were using a particular tag and all used the associated subfield codes, the acceptance of those subfield codes was calculated as 100 percent. in both tables 1 and 2, the columns on indicators and subfield codes include responses only from those libraries that were definitely using the tag with which a given indicator or subfield code was associated. the analysis excludes tags for which no immediate implementation is planned by the marc distribution service. table 2. percentage of acceptance

7 7 subfield codes (181) 10 134 32 5 the major findings of this analysis may be summarized as follows: 1) of 19 fixed fields, 14 were used by at least half of the libraries and all were used by at least one library. 2) of 63 tags, 43 were used by at least half of the libraries and 26 were used by all of them. seven tags were not used by any of the libraries studied, but these tags cover items that will appear in machine records produced by the national library of medicine, the national agricultural library, and the british national bibliography. 3) of 126 indicators, only 18 were used by at least half of the libraries. the highest degree of acceptance was the use of the same two indicators by six libraries. on the other hand, each indicator was used by at least two libraries. 4) of 181 subfield codes, 176 were used by at least half of the libraries that were using the related tags. each subfield code was used by at least a quarter of the libraries that could express a relevant opinion. 126 journal of library automation vol. 3/ 2 june, 1970 the foregoing analysis confirmed the view that a nationally distributed record should be as rich in content designation as possible. failure to provide this detail would result in many libraries having to enrich the record to satisfy local needs, a process more costly than deleting items selectively. therefore, as of now, the present marc ii format constitutes the level required to satisfy the national distribution function. the national union catalog function as noted above, the nuc function relates to the use of machine readable records to build a national union catalog. at first thought, it might appear that this function overlaps the distribution function. as far as library of congress cataloging is concerned, this view is correct. it is valid also with respect to cooperative cataloging entries issued by the library as part of the card service. however, the two functions are quite distinct as far as regular reports to nuc are concerned. the essential difference between the two categories of catalog records is that those issued as lc cards have been completely checked against the library's authority files and edited for consistency, whereas only the main and added entries of nuc reports have been checked for compatibility. the impact of this difference can be judged from the fact that an attempt to distribute nuc reports as proof slips several years ago was abandoned because the response to this service did not justify its continuance. distributing nuc reports in machine readable form would add another dimension to the problem of processing them, because, to be flexible enough for wide acceptance, nuc reports would have to be entirely compatible with those issued by the marc distribution service. since compatibility would involve more detailed content designation than many libraries might put into their records for local use, libraries would have to be willing to provide this detail in nuc reports, or the level of nuc reports would have to be upgraded centrally. as the certification of the bibliographic data and the content designators would entail a major workload for the library of congress, it does not seem practical to pursue this goal at present. it is possible, however, to define a subset of content designators to cover the eventuality that outside libraries may be able to report their holdings to nuc in machine readable fmm. a marc subset can be determined for the nuc function because this function involves processing records in a multiplicity of places to be used centrally for specifically definable purposes. the distribution function, on the other hand, involves the preparation of records at a central somce to be used for a wide variety of purposes in a multiplicity of places. the difference is vital when it comes to stating the requirements for the two types of records. levels of machine readable recordsfrecon task force 127 the specifications of a machine readable record to fulfill the nuc function depend on the nature and functions of the national union catalog itself. the content designators for such a record will be defined in a separate investigation now being conducted by the working task force. the present study was considered to be completed once the feasibility of defining a level of machine readable record for that purpose was established. conclusion the findings of this study of the feasibility of defining levels of machine readable bibliographic records are as follows: 1) the level of a record must be adequate for the purposes it will serve. 2) in terms of national use, a machine readable record may function as a means of distributing cataloging information and as a means of reporting holdings to a national union catalog. 3) to satisfy the needs of diverse installations and applications, records for general distribution should be in the full marc ii format. 4) records that satisfy the nuc function are not

• maturity level 2: managed (planning, performance, measurement and control occur on the project level); • maturity level 3: defined (proactive, rather than reactive, with organization-wide standards); • maturity level 4: quantitatively managed (data-driven with shared, predictable, quantitative performance improvement objectives that align to meet the needs of internal and external stakeholders); and • maturity level 5: optimizing (stable, flexible, agile, responsive, and focused on continuous improvement).6 application of maturity models within user experience work in libraries thus far, discussion of maturity models in the library literature relevant to web librarianship has primarily centered on user experience (ux) work. in their 2020 paper “user experience methods and maturity in academic libraries,” young, chao, and chandler noted, “. . . several different ux maturity models have been advanced in recent years,” reviewing approximately a half-dozen approaches with varying emphases and numbers of stages.7 in 2013, coral sheldon-hess developed the following five-stage model, based on the aforementioned cmmi framework, for assessing maturity of ux practice in library organizations: 1 – decisions are made based on staff’s preferences, management’s pet projects. user experience [of patrons] is rarely discussed. 2 – some effort is made toward improving the user experience. decisions are based on staff’s gut feelings about patrons’ needs, perhaps combined with anecdotes from service points. 3 – the organization cares about user experience; one or two ux champions bring up users’ needs regularly. decisions are made based on established usability principles and studies from other organizations, with occasional usability testing. information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 3 4 – user experience is a primary motivator; most staff are comfortable with ux principles. users are consulted regularly, not just for major decisions, but in an ongoing attempt at improvement. 5 – user experience is so ingrained that staff consider the usability of all of their work products, including internal communications. staff are actively considerate, not only toward users but toward their coworkers.8 as an indicator of overall ux maturity within an organization, sheldon-hess focuses on “consideration” in interactions not only between library staff and library patrons, but also between library staff: “when an organization is well and truly steeped in ux, with total awareness of and buy-in on user-centered thinking, its staff enact those principles, whether they’re facing patrons or not.”9 in 2017, macdonald conducted a series of semi-structured interviews with 16 ux librarians to investigate, among other things, “the organizational aspects of ux librarianship across various library contexts.”10 macdonald proposes a five-stage model, broadly similar in concept to the cmmi institute structure and to sheldon-hess’s model. most compelling, however, were these three major findings, taken from macdonald’s list: • some (but not all) ux librarian positions were created as part of purposeful and strategic efforts to be more self-aware; . . . • the biggest challenges to doing ux are navigating the complex library culture, balancing competing responsibilities, and finding ways to more efficiently employ ux methods; an d • the level of co-worker awareness of ux librarianship is driven by the extent to which ux work is visible and by the individual ux librarian’s ability to effectively communicate their role and value.11 based on analysis of the results of their 2020 survey of library ux professionals, in which they asked respondents to self-diagnose their organizations, young, chao, and chandler presented, for use in libraries, their adaptation of the nielsen norman group’s eight-stage scale of ux maturity: • stage 1: hostility toward usability / stage 2: developer-centered ux—apathy or hostility to ux practice; lack of resources and staff for ux. • stage 3: skunkworks ux—ad hoc ux practices within the organization; ux is practiced, but unofficially and without dedicated resources or staff; leadership does not fully understand or support ux.12 • stage 4: dedicated ux budget—leadership beginning to understand and support ux; dedicated ux budget; ux is assigned fully or partly to a permanent position. • stage 5: managed usability—the ux lead or ux group collaborates with units across the organization and contributes ux data meaningfully to organizational and strategic decision-making. • stage 6: systematic user-centered design process—ux research data is regularly included in projects and decision-making; a wide variety of methods are practiced regularly by multiple departments. • stage 7: integrated user-centered design / stage 8: user-driven organization—ux is practiced throughout the organization; decisions are made and resources are allocated only with ux insights as a guide.13 information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 4 young et al.’s findings supported macdonald’s, underscoring the importance of shared organizational understandings, priorities, and culture related to ux activities and personnel: ux maturity in libraries is related to four key factors: the number of ux methods currently in use; the level of support from leadership in the form of strategic alignment, budget, and personnel; the extent of collaboration throughout the organization; and the degree to which organizational decisions are influenced by ux research. when one or more of these four connected factors advances, so too does ux maturity. 14 these findings are consistent with larger patterns in the management of library-authored web content identified in the earlier cited literature review: inconsistent processes, disconnects between units, varying constituent goals, and vague or ineffective wcm governance structures are recurrent themes throughout the literature . . . web content governance issues often signal a lack of coordination, or even of unity, across an organization.15 assessing the maturity of content strategy practice in libraries we consider kristina halverson’s definition of content strategy, offered in content strategy for the web, as the authoritative definition. halverson states: “content strategy is the practice of planning for the creation, delivery, and governance of useful, usable content.”16 this definition can be divided into five elements: 1. planning: intentionality and alignment, setting goals, discovery and auditing, connecting to strategic a plan or vision 2. creation: roles, responsibilities, and workflows for content creation; attention to content structure; writing or otherwise developing content in its respective format 3. delivery: findability of content within site and more broadly (i.e., search engine optimization), use of distinct communication channels 4. governance: maintenance and lifecycle management of content through coordinated process and decision making; policies and procedures; measurement and evaluation through analysis of usage data, testing, and other means 5. useful/usable (hereafter referred to as ux): relevant, current, clear, concise, and in context jones discusses the application of content strategy–specific maturity models as a potential tool for content strategists: “the[se] model[s] can help your company identify your current level of content operations, . . . decide whether that level will support your content vision and strategy . . . [and] help you plan to get to the next level of content operations.”17 three examples of maturity models developed for use by content strategy industry professionals map industry-specific terms, tools, and actions to the level-based structure put forward by the cmmi institute (see table 1). information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 5 table 1. comparative table of content strategy maturity models content strategy, inc.18 [2016] jones (gathercontent)19 [2018] randolph (kapost)20 [2020] ad hoc: inconsistent quality, lack of uniform practice, little or no opportunity to understand customer needs chaotic: no formal content operations, only ad hoc approaches reactive: chaotic, siloed, lacking clarity, chronically behind rudimentary: movement toward structure, unified process and voice; can be derailed by timelines, resistance piloting: trying content operations in certain areas, such as for a blog siloed: struggles to collaborate, poorly defined and inconsistently measured goals organized & repeatable: strong leadership, uniform process and voice has become routine, integration of userfocused data collection scaling: expanding formal content operations across business functions mobilizing: varying collaboration, content is centralized but not necessarily accessible, defined strategy sometimes impacted by ad hoc requests managed & sustainable: larger buy-in across organization, can sustain changes in leadership, increased number and sophistication of methods sustaining: solidifying and optimizing content operations across business functions integrating: effective collaboration across multiple teams, capability for proactive steps, still struggle to prove roi optimized: close alignment to strategic objectives, integration across the organization, leadership within and outside the organization thriving: sustaining while also innovating and seeing return on investment (roi) optimizing: cross-functional collaboration results in seamless customer messaging and experiences, consistently measured roi contributes to planning while these models have some utility for content strategy practitioners in higher education, including those in academic and research libraries, emphasis on commercial standards for assessing success (e.g., business goals, centrally managed marketing) limits their direct application in the academic environment. the 2017 blog post by tracey playle, “ten pillars for getting the most of your content: how is your university doing?”, presented ten concepts paired with questions, which could be used by higher education content professionals to reflect on their current state of practice.21 this model was developed for use by a consultancy, and the “pillars”—”strategy and vision,” “risk tolerance and creativity,” and “training and professional development”— are more broadly conceived than typical maturity models. thus, this approach seems more appropriate as a personal or management planning tool rather than as a model for evaluating maturity across library organizations. information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 6 methods following review and approval by the researchers’ institutional review boards, a web-based survey collecting information about existing workflows for web content, basic organizational information, and familiarity with concepts related to web content strategy was distributed to 208 professionals in april 2020. the survey was available for four weeks. participants were drawn from academic and research libraries across north america, providing their own opinions as well as information on behalf of their library organization. (see appendix a: institution list.) the sample group (n=208) was composed of north american academic and research libraries that are members of the following nationally and regionally significant membership organizations (excluding non-academic member institutions): the association of research libraries, the big ten academic alliance, the greater western library alliance, and/or the oberlin group. some libraries are members of multiple groups. details are supplied below in table 3. we identified individuals (n=165) based on their professional responsibilities and expertise using the following order and process: 1. individual job title contains some combinations of the following words and/or phrases: content strategy, content specialist, content strategist, web content, web communications, digital communications, digital content 2. head of web department or department email 3. head of ux department or department email 4. head of it or department email for institutions where a specific named individual could not be identified through a review of the organizational website, we identified a general email (e.g., libraries@state.edu) as the contact (n=43). a mailing list was created in mailchimp, and two campaigns were created: one for named individuals, and one for general contacts. only one response was requested per institution. (see appendix b: recruitment emails.) the 165 named individuals, identified as described above, received a personalized email inviting them to participate in the study. the recruitment email explained the purpose of the study, advised potential participants of possible risks and their ability to withdraw at any time, and included a link to the survey. a separate email was sent to the 43 general contacts on the same day, explaining the purpose of the study, and requesting that the recipient forward the communication to the appropriate person in the organization. this email also included information advising potential participants of possible risks and their ability to withdraw at any time, and a link to the survey. data was recorded directly by participants using qualtrics. the bulk of survey data does not include any personal information; we did not collect the names of institutions as part of our data collection, so identifying information is limited to information about institutional memberships. for the group of named individuals, one email bounce was recorded. the open rate for personalized emails sent to named individuals was approximately 62% (88 of 142 successfully delivered emails were opened) and the survey link was followed 66 times. the general email group had a 51% open rate (n=22) with 11 clicks of the survey link. with recruitment occurring in april 2020, most individuals and institutions were at the height of switching to remote operations information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 7 in light of the covid-19 pandemic. despite this, our open rates were considerably higher than average open rates as reported by mailchimp.22 as discussed below, we achieved our minimum response rate goal of 20%. table 2. survey question topics and response count question topic category response count 1 consent — 43 2 organizational memberships demographic 40 3 approx. # full-time employees demographic 41 4 cms products used infrastructure/ organizational structure 41 5 primary cms infrastructure/ organizational structure 39 6 number of site editors infrastructure/ organizational structure 39 7 describe responsibility for content infrastructure/ organizational structure 39 8 existence of position(s) with primary duties of web content infrastructure/ organizational structure 39 9 titles of such positions, if any infrastructure/ organizational structure 24 10 familiar with web content strategy content strategy practices 36 11 definition of web content strategy content strategy practices 32 12 policies or documentation content strategy practices 35 13 methods content strategy practices 37 14 willing to be contacted — 37 15 name — 27 16 email — 26 the survey included 16 questions; question topics and response counts are noted in table 2. informed consent was obtained as part of the first survey question. (see appendix c: survey questions and appendix d: informed consent document.) most questions were multiple-choice or short answer (i.e., a number). two questions required longer-form responses. information collected fell into the following three categories: information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 8 • demographics (estimated total number of employees; institutional memberships; estimated number of employees with website editing privileges) • infrastructure and organizational structure (content management systems used to manage library-authored web content; system used to host primary public-facing website; distribution of responsibility for website content; titles of positions (if any) whose primary responsibilities focus on web content) • web content strategy practices (familiarity with; personal definition; presence or absence of policy or documentation; evaluation methods regularly used) upon completion of the survey questions, participants had the option to indicate that they would be willing to be contacted for an individual interview as part of planned future research on this topic. twenty-seven individuals (63%) opted in and provided us with their contact information. findings in sum, 43 responses were received, resulting in a response rate of 20.67%. because we did not collect names of individuals or institutions and used an anonymous link for our survey, we cannot determine the ultimate response rate by contact group (named individuals or general email). demographic information the bulk of responses came from association of research libraries members, but within-group response rates show that the proportion of responses from each group was relatively balanced within the overall 20% response rate. table 3. distribution of survey contacts, responses, and response rates by group23 organization member libraries contacted responses share of total responses (%) group response rate (%) association of research libraries 117 26 50.98 22.22 big ten academic alliance 15 5 9.8 33.0 greater western library alliance 38 8 15.69 21.05 oberlin group 80 12 23.53 15.0 infrastructure & organizational structure content management systems a variety of content management systems are used to manage library-authored web content (see table 4); libguides, wordpress, omeka, and drupal were most commonly used across the group. other systems mentioned as write-in responses included acquia drupal, cascade, fedora-based systems, archivesspace, google sites, and “wiki and blog.” one response stated, “most pages are just non-cms for the website.” write-in responses for “other” and “proprietary system hosted by institution” were carried forward within the survey from question 3 to question 4, and are available in full in appendix e: other content management systems mentioned by respondents. information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 9 table 4. cms products used to manage library-authored web content q3: cms products used percentage (%) count libguides 28.06 39 wordpress 18.71 26 omeka 15.11 21 drupal 13.67 19 other 9.35 13 sharepoint 7.19 10 proprietary system hosted by institution 7.19 10 adobe experience manager 0.72 1 total 100 139 for their primary library website, just under half of respondents relied on drupal (n=17, 43.59%). slightly fewer selected the specific system, whether the institution’s proprietary system or some other option, that they had shared as a write-in answer for the previous question; in total just under 36% (n=14). despite the widespread use reported in the previous question, only two respondents indicated that their primary website was hosted in libguides.

in fact, no single definition touched on both. overall, the results of the analysis of provided definitions (discussed in the previous section) suggest that at present, web content strategy as a community of practice in academic libraries is operating at, or just above, a basic level. proposed maturity model from these findings, and referencing the structure of the cmmi institute five-stage maturity model, the authors propose the following proposed content strategy maturity model for academic libraries. as previously noted in our findings, we assess the web content strategy community of practice in academic libraries as operating at, or just above, a basic level. to align the proposed maturity model with the definition scores, we applied the 10-point rating scale for provided definitions to the five levels by assigning two points per level, so a score of one or two would be equivalent to level 1, a score of three or four equivalent to level 2, and so on (table 11). table 11. comparison of maturity model with definition rating scale and maturity assessment maturity model level definition score assessment level 1 1 basic level 1 2 basic level 2 3 basic level 2 4 intermediate level 3 5 intermediate level 3 6 intermediate level 4 7 intermediate level 4 8 advanced level 5 9 advanced level 5 10 advanced content strategy maturity model for academic libraries level 1: ad hoc • no planning or governance • creation and delivery are reactive, distributed, and potentially chaotic • no or minimal consideration of ux level 2: establishing • some planning and evidence of strategy, such as use of content audits and creation of a style guide;

these measures suggest that the majority of survey respondents’ organizational web content strategy maturity levels would currently stand at level 2 or 3, with a few at level 1. conclusion the findings of this survey and assessment, while inherently limited, suggest that web content strategy is currently not a pervasive factor for academic libraries and academic web librarians in the development and implementation of actions, policies, and practices related to website creation, maintenance, and evaluation. we have proposed a measure for self-estimating the maturity of web content strategy practice for academic libraries. our content strategy maturity model for academic libraries, while grounded both in industry best practices and in evidence from practitioners in academic libraries, is nonetheless a work in progress. we intend to further develop and strengthen the model through follow-up interviews with practitioners, drawing on those survey respondents who opted-in to being contacted. interviewees will be invited to discuss their work within and outside the frame of the proposed maturity model, and to provide feedback on the model itself, with the ultimate goal of enabling a better understanding of web content strategy practice in academic libraries and the needs of its community of practice. endnotes 1 courtney mcdonald and heidi burkhardt, “library-authored web content and the need for content strategy,” information technology and libraries 38, no. 3 (september 15, 2019): 8–21, https://doi.org/10.6017/ital.v38i3.11015. 2 mcdonald and burkhardt, 14. 3 mcdonald and burkhardt, 16. 4 “cmmi levels of capability and performance,” sec. maturity levels, cmmi institute llc, accessed may 28 2020, https://cmmiinstitute.com/learning/appraisals/levels. 5 “about cmmi institute,” cmmi institute llc, accessed may 28 2020, https://cmmiinstitute.com/company. 6 “cmmi levels of capability and performance,” sec. maturity levels. 7 scott w. h. young, zoe chao, and adam chandler, “user experience methods and maturity in academic libraries,” information technology and libraries 39, no. 1 (march 16, 2020): 2, https://doi.org/10.6017/ital.v39i1.11787. 8 coral sheldon-hess, “ux, consideration, and a cmmi-based model,” para. 6, july 25, 2013, http://www.sheldon-hess.org/coral/2013/07/ux-consideration-cmmi/. 9 sheldon-hess, “ux, consideration, and a cmmi-based model,” para. 2, http://www.sheldonhess.org/coral/2013/07/ux-consideration-cmmi/. https://doi.org/10.6017/ital.v38i3.11015 https://cmmiinstitute.com/learning/appraisals/levels https://cmmiinstitute.com/company https://doi.org/10.6017/ital.v39i1.11787 http://www.sheldon-hess.org/coral/2013/07/ux-consideration-cmmi/ http://www.sheldon-hess.org/coral/2013/07/ux-consideration-cmmi/ http://www.sheldon-hess.org/coral/2013/07/ux-consideration-cmmi/ information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 18 10 craig m. macdonald, “‘it takes a village’: on ux librarianship and building ux capacity in libraries,” journal of library administration 57, no. 2 (february 17, 2017): 196, https://doi.org/10.1080/01930826.2016.1232942. 11 macdonald, 212. 12 skunk works is trademarked by lockheed martin corporation, but is informally used to describe an experimental, sometimes secret, research and development group focused on agile innovation. 13 young, chao, and chandler, “user experience methods and maturity in academic libraries,” 19. 14 young, chao, and chandler, 23. 15 mcdonald and burkhardt, “library-authored web content and the need for content strategy,” 15–16. 16 kristina halvorson, content strategy for the web, 2nd ed.

write-in responses for ‘proprietary system hosted by institution’ ● xxxxxxxxxxx • archivesspace • pressbooks • preservica • hippo cms • siteleaf • cascade • dotcms • terminal four • acquia drupal • fedora based digital collections system built in house write-in responses for ‘other” • wiki and blog • we draft content in google docs & also use gather content for auditing. • google sites • cascade • ebsco stacks • modx • islandora and online journal system • contentful • we also have some in-house-built tools such as for room booking; some of these are quite old and we would like to upgrade or improve them when we can. (very few people can make edits in these tools.) • cascade • the majority of the library website (and university website) is managed by a locally developed cms; however, the university is in the process of migrating to the acquia drupal cms. • blacklight, vivo, fedora • most pages are just non-cms for the website information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 40 appendix f: organizational responsibility for content; and position titles question 6 please explain how your organization distributes responsibility for content hosted in your content management system(s). if different parties (individuals, departments, collaborative groups) are responsible for managing content in different platforms please describe. • we have one primary website manager who oversees the management of the website, including content strategy and editing, and 2 editors who assist with small editing tasks. • we have content editors that edit content for individual libraries and collections. there is a content creator network managed by library communications. they provide trainings and guidance for content editors and act as reviewers, but not every single thing gets reviewed. • we have a team of developers and product owners who are responsible for managing web content. • we currently have a very distributed model, where virtually any library staff member or student assistant can request a drupal account and then make changes to existing content or develop new pages. we have a cross-departmental team that oversees the libraries' web interfaces and makes decisions about library homepage content, the menu navigation, overall ia, etc. we have web content guidelines to help staff as they develop new content. we have identified functional and technical owners for each of our cmss and have slightly different processes for managing content in those cmss. our general approach, however, is very inclusive (for better or worse ;) )-lots of staff have access to creating and editing content. we are, however, moving to a less distributed content for drupal in particular. moving forward, we'll have a small team responsible for editing and developing new content. this is to ensure that content is more consistent and user-centered. we attempted to identify funding for a full-time content manager but were unsuccessful, so this team will attempt to fill the role of a full-time content manager. • ux is the product owner and admin. if staff want content added to the website, they send a request to ux, we structure and edit content in a google doc, and then ux posts to the website. • there's no method for how or why responsibility is distributed. it ends up being something like, someone wants to add some content, they get editing access, they can now edit anything for as long as they're at the library. we are a super decentralized and informal library. • the primary content managers are the xxxxxx librarian and the xxxxxx. other individuals (primarily librarians) that are interested in editing their content have access on our development server. their edits are vetted by the xxxxxxand/or the xxxxxx librarian before being moved into production. • the xxxxxx department (6 staff) manages content and helps staff throughout the organization create and maintain content. ux staff sometimes teach others how to manage content, and sometimes do it for them. if design or content is complex, usually ux staff do the work. many staff don't maintain any content beyond their staff pages. subject specialists and instruction librarians maintain content [like] libguides-like content, but we don't use libguides. branch library staff maintain most of the content for their library pages. information technology and libraries march 2021 web content strategy in practice within academic libraries | mcdonald and burkhardt 41 • in addition, the xxxxxx manages the catalog. the xxxxxx department manages special web projects. and the xxxxxx department manages social media, publications, and news. • a web content team made up of two administrators and librarians from xxxxxx and xxxxxx makes executive-level decisions about web content. • the xxxxxx team (xxxxxx) provides oversight and consulting for online user interfaces chaired by a xxxxxxposition which is new and is not yet filled. • for the public website, content editing is distributed to many groups and teams throughout the libraries. • the xxxxxxteam manages the main portions of the site including the homepage, news, maps, calendars, etc. the research librarians and subject liaisons manage the research guides. the xxxxxx provides guidance regarding overall responsibilities and style guidelines. • site structure and top-level pages for our main website resides with xxxxxx. page content is generally distributed to the departments closest to the services described by the pages. • right now editing of pages is distributed to those individuals who have the closest relationship to the pages being edited, with a significantly smaller number of people having administrative access to all of the libraries' websites. • primary website is co-managed by xxxxxx team (4 people) and xxxxxx team (3 people). xxxxxxteam creates timely content about news/events/initiatives while xxxxxx team manages content on evergreen topics. • research librarians and staff manage libguides content, which is in sore need of an inventory and pruning. • primarily me, plus two colleagues who serve with me as a web editorial board • one librarian manages the content and makes changes based on requests from other library staff • my role (xxxxxx) is xxxxxx. we also have a web content creator in our xxxxxx. i chair our xxxxxxgroup (xxxxxx), which has representatives from each division in the library and they are the primary stewards of supporting library

is a xxxxxx [group] member due to its scope and scale. in our primary website, we are currently structured around drupal organic groups for content management with xxxxxx [group] having broad editing access. in our new website, all content management will go through the xxxxxx, with communications for support and dynamic content (homepage, news, events) management. • management is somewhat in flux right now. we recently migrated our main web site to acquia drupal; there is a very new small committee consisting of xxxxxx, and three representatives from elsewhere in the library. for libguides, all reference, instructio n, and subject librarians can edit their own guides; the xxxxxx has tended to have final oversight but i don't know if this has ever been formally delegated. • librarians manage their own libguides subject guides; several members of xxxxxx can make administrative changes to coding, certificates, etc. on the entire site; there are individuals in different departments who control their own pages/libguides. there is a group within the library that administers wordpress for the institution. other content systems are administered by individuals within the library.

xxxxxx staff have the ability to create and edit exhibition content in drupal. xxxxxx staff and xxxxxx staff have the ability to create and edit equipment content. the event coordinator and librarians and staff involved in instruction are allowed to create and edit event and workshop listings. • only the communication coordinator is permitted to create news items that occupy real estate on the home page and various service point home pages. • as for general content, the primary internal stakeholders for that content typically create and edit that content, but if any staff notice a typo or factual error they are encouraged to correct them on their own, although they can also submit a request to the it department if they are not comfortable doing so. • subject specific content is hosted in libguides, and is maintained by subject liaison librarians. other content in libguides, software tutorials or information related to electronic resources for example, is created and maintained by appropriate specialists. • the drupal site when launched had internal stakeholders explicitly defined for each page, and only staff from the appropriate group could edit that content (e.g. if xxxxxx was tagged as the only stakeholder for a page about xxxxxx policies, then only staff from the xxxxxx department with editing privileges could edit that page). this system was abandoned after about two years as it was considered too much overhead to maintain and also the introduction of a content revisioning module that kept a history of edits alleviated fears of malicious editing. • individuals are assigned pages to keep content updated. the xxxxxx is responsible for coordinating with those staff and offers training to make sure content gets updated. • individual liaison librarians are responsible for their own libguides. i and the "xxxxxx" are the primary editors of the wordpress site, although 4 others have editing access (an employee who writes and posts news articles, the liaison librarian who spearheaded our new video tutorials, and two who work in special collections to update finding aids on that site, which is still on wordpress and i would consider under the main libraries web page, but is part of a multisite installation.) • in omeka and libguides, librarians are pretty self-sufficient and responsible for all of their own content. the three or four digital projects faculty and staff who work with omeka manage it internally alongside one of our developers. our omeka instance is relatively small-scale. • i (xxxxxx) oversee our libguides environment. while i am in the process of creating and implementing formal libguides content and structure guidelines, as of now it's a bit of a free-for-all with everyone responsible for the content pertaining to their own liaison department(s). content is made available to patrons via automatically populating legacy landing pages (we've had libguides for a decade and i've been with the institution not yet a year).

the content in our wordpress environment. that said, i try to distribute content upkeep responsibilities to the relevant department for each piece of the site. managers and committee chairs provide me with what they want on the web, and as needed (and in consultation with them) i review/rewrite it for the web (plain language), develop information architecture, design the front-end, and accessibly publish the content. there are only a few faculty and staff at my library who are comfortable with wordpress -but one of my long-term goals is to empower more folks to enact their own minor edits (e.g., updating hours, lending policies, etc.) while i oversee large-scale content creation, overall architecture, and strategy. we have a blog portion of our wordpress site which is not managed by anyone in particular, but i tend to clean it up if things go awry. • generally all of our web authors *can* publish to most parts of the site. (a very few content types (mostly featured images that display on home pages) can be edited only by admins and a small number of super-users.) however the great majority of people who can post content very rarely do (and some never do). some edit or post only to specific blogs, some only to their own guides or to very specific pages or suites of pages (e.g. liaison librarians to their own guides; thesis assistant to thesis pages). our small group in xxxxxx reviews new and updated pages and edits for in-house style and usability guidelines, and also trains and works collaboratively with web authors to create more usable content and reduce duplication -but given the large number of authors (with varied priorities, skills, and preferences) and pages we have trouble keeping up. we also more actively manage content on home pages. • for the main website and intranet, we have areas broken apart by unit area. we use workbench access to determine who can edit which pages. libguides is managed by committee, but most of the librarians have access. proprietary systems have separate accounts for those who need access. • for libguides, librarians can create content as they like, though there is a group that provides some (light) oversight. for main library website, most content is overseen by departments (in practice, one person each from a handful of “areas”, such as the branches, access services, etc.). • dotcms is primarily managed in systems (2 staff), with delegates from admin and outreach allowed to make limited changes to achieve their goals. libguides is used by all librarians and several staff, with six people given admin privileges. wordpress is used only in special collections. • xxxxxx dept manages major public facing platforms (drupal, wordpress, and shares libguides responsibilities with xxxxxx dept). xxxxxx manages omeka. within platforms, responsibilities are largely managed by department with individuals assigned content duties & permissions as needed. • different units maintain their content; one unit has overall management and checks for uniformity, needed updates, and broken links. • developers/communications office oversees some aspects, library management, research and collections librarians, and key staff edit other pieces. • currently, content is maintained by the xxxxxx librarian in coordination with content stakeholders from around the

55 martha m. yee can bibliographic data be put directly onto the semantic web? this paper is a think piece about the possible future of bibliographic control; it provides a brief introduction to the semantic web and defines related terms, and it discusses granularity and structure issues and the lack of standards for the efficient display and indexing of bibliographic data. it is also a report on a work in progress—an experiment in building a resource description framework (rdf) model of more frbrized cataloging rules than those about to be introduced to the library community (resource description and access) and in creating an rdf data model for the rules. i am now in the process of trying to model my cataloging rules in the form of an rdf model, which can also be inspected at http://myee. bol.ucla.edu/. in the process of doing this, i have discovered a number of areas in which i am not sure that rdf is sophisticated enough yet to deal with our data. this article is an attempt to identify some of those areas and explore whether or not the problems i have encountered are soluble—in other words, whether or not our data might be able to live on the semantic web. in this paper, i am focusing on raising the questions about the suitability of rdf to our data that have come up in the course of my work. t his paper is a think piece about the possible future of bibliographic control; as such, it raises more complex questions than it answers. it is also a report on a work in progress—an experiment in building a resource description framework (rdf) model of frbrized descriptive and subject-cataloging rules. here my focus will be on the data model rather than on the frbrized cataloging rules for gathering data to put in the model, although i hope to have more to say about the latter in the future. the intent is not to present you with conclusions but to present some questions about data modeling that have arisen in the course of the experiment. my premise is that decisions about the data model we follow in the future should be made openly and as a community rather than in a small, closed group of insiders. if we are to move toward the creation of metadata that is more interoperable with metadata being created outside our community, as is called for by many in our profession, we will need to address these complex questions as a community following a period of deep thinking, clever experimentation, and astute political strategizing. n the vision the semantic web is still a bewitching midsummer night’s dream. it is the idea that we might be able to replace the existing html–based web consisting of marked-up documents—or pages—with a new rdf– based web consisting of data encoded as classes, class properties, and class relationships (semantic linkages), allowing the web to become a huge shared database. some call this web 3.0, with hyperdata replacing hypertext. embracing the semantic web might allow us to do a better job of integrating our content and services with the wider internet, thereby satisfying the desire for greater data interoperability that seems to be widespread in our field. it also might free our data from the proprietary prisons in which it is currently held and allow us to cooperate in developing open-source software to index and display the data in much better ways than we have managed to achieve so far in vendor-developed ils opacs or in giant, bureaucratic bibliographic empires such as oclc worldcat. the semantic web also holds the promise of allowing us to make our work more efficient. in this bewitching vision, we would share in the creation of uniform resource identifiers (uris) for works, expressions, manifestations, persons, corporate bodies, places, subjects, and so on. at the uri would be found all of the data about that entity, including the preferred name and the variant names, but also including much more data about the entity than we currently put into our work (name-title and title), such as personal name, corporate name, geographic, and subject authority records. if any of that data needed to be changed, it would be changed only once, and the change would be immediately accessible to all users, libraries, and library staff by means of links down to local data such as circulation, acquisitions, and binding data. each work would need to be described only once at one uri, each expression would need to be described only once at one uri, and so forth. very much up in the air is the question of what institutional structures would support the sharing of the creation of uris for entities on the semantic web. for the data to be reliable, we would need to have a way to ensure that the system would be under the control of people who had been educated about the value of clean and accurate entity definition, the value of choosing “most commonly known” preferred forms (for display in lists of multiple different entities), and the value of providing access martha m. yee (myee@ucla.edu) is cataloging supervisor at the university of california, los angeles film and television archive. 56 information technology and libraries | june 2009 under all variant forms likely to be sought. at the same time, we would need a mechanism to ensure that any interested members of the public could contribute to the effort of gathering variants or correcting entity definitions when we have had inadequate information. for example, it would be very valuable to have the input of a textual or descriptive bibliographer applied to difficult questions concerning particular editions, issues, and states of a significant literary work. it would also be very valuable to be able to solicit input from a subject expert in determining the bounds of a concept entity (subject heading) or class entity (classification). n the experiment (my project) to explore these bewitching ideas, i have been conducting an experiment. as part of my experiment, i designed a set of cataloging rules that are more frbrized than is rda in the sense that they more clearly differentiate between data applying to expression and data applying to manifestation. note that there is an underlying assumption in both frbr (which defines expression quite differently from manifestation) and on my part, namely that catalogers always know whether a given piece of data applies at either the expression or the manifestation level. that assumption is open to questioning in the process of the experiment as well. my rules also call for creating a more hierarchical and degressive relationship between the frbr entities work, expression, manifestation, and item, such that data pertaining to the work does not need to be repeated for every expression, data pertaining to the expression does not need to be repeated for every manifestation, and so forth. degressive is an old term used by bibliographers for bibliographies that provide great detail about first editions and less detail for editions after the first. i have adapted this term to characterize my rules, according to which the cataloger begins by describing the work; any details that pertain to all expressions and manifestations of the work are not repeated in the expression and manifestation descriptions. this paper would be entirely too long if i spent any more time describing the rules i am developing, which can be inspected at http://myee.bol.ucla .edu. here, i would like to focus on the data-modeling process and the questions about the suitability of rdf and the semantic web for encoding our data. (by the way, i don’t seriously expect anyone to adopt my rules! they are radically different than the rules currently being applied and would represent a revolution in cataloging practice that we may not be up to undertaking in the current economic climate. their value lies in their thought-experiment aspect and their ability to clarify what entities we can model and what entities we may not be able to model.) i am now in the process of trying to model my cataloging rules in the form of an rdf model (“rdf” as used in this paper should be considered from now on to encompass rdf schema [rdfs], web ontology language [owl], and simple knowledge organization system [skos] unless otherwise stated); this model can also be inspected at http://myee.bol .ucla.edu. in the process of doing this, i have discovered a number of areas in which i am not sure that rdf is yet sophisticated enough to deal with our data. this article is an attempt to outline some of those areas and explore whether the problems i have encountered are soluble, in other words, whether or not our data might be able to live on the semantic web eventually. i have already heard from rdf experts bruce d’arcus (miami university) and rob styles (developer of talis, as semantic web technology company), whom i cite later, but through this article i hope to reach a larger community. my research questions can be found later, but first some definitions. n definition of terms the semantic web is a way to represent knowledge; it is a knowledge-representation language that provides ways of expressing meaning that are amenable to computation; it is also a means of constructing knowledgedomain maps consisting of class and property axioms with a formal semantics rdf is a family of specifications for methods of modeling information that underpins the semantic web through a variety of syntax formats; an rdf metadata model is based on making statements about resources in the form of triples that consist of 1. the subject of the triple (e.g., “new york”); 2. the predicate of the triple that links the subject and the object (e.g., “has the postal abbreviation”); and 3. the object of the triple (e.g., “ny”). xml is commonly used to express rdf, but it is not a necessity; it can also be expressed in notation 3 or n3, for example.1 rdfs is an extensible knowledge-representation language that provides basic elements for the description of ontologies, also known as rdf vocabularies. using rdfs, statements are made about resources in the form of 1. a class (or entity) as subject of the rdf triple (e.g., “new york”); 2. a relationship (or semantic linkage) as predicate of the rdf triple that links the subject and the object (e.g., can bibliographic data be put directly onto the semantic web? | yee 57 “has the postal abbreviation”); and 3. a property (or attribute) as object of the rdf triple (e.g., “ny”). owl is a family of knowledge representation languages for authoring ontologies compatible with rdf. skos is a family of formal languages built upon rdf and designed for representation of thesauri, classification schemes, taxonomies, or subject-heading systems. n research questions actually, the full-blown semantic web may not be exactly what we need. remember that the fundamental definition of the semantic web is “a way to represent knowledge.” the semantic web is a direct descendant of the attempt to create artificial intelligence, that is, of the attempt to encode enough knowledge of the real world to allow a computer to reason about reality in a way indistinguishable from the way a human being reasons. one of the research questions should probably be whether or not the technology developed to support the semantic web can be used to represent information rather than knowledge. fortunately, we do not need to represent all of human knowledge—we simply need to describe and index resources to facilitate their retrieval. we need to encode facts about the resources and what the resources discuss (what they are “about”), not facts about “reality.” based on our past experience, doing even this is not as simple as people think it is. the question is whether we could do what we need to do within the context of the semantic web. sometimes things that sound simple do not turn out to be so simple in the doing. my research questions are as follows: 1. is it possible for catalogers to tell in all cases whether a piece of data pertains to the frbr expression or the frbr manifestation? 2. is it possible to fit our data into rdf? given that rdf was designed to encode knowledge rather than information, perhaps it is the wrong technology to use for our purposes? 3. if it is possible to fit our data into rdf, is it possible to use that data to design indexes and displays that meet the objectives of the catalog (i.e., providing an efficient instrument to allow a user to find a particular work of which the author and title are known, a particular expression of a work, all of the works of an author, all of the works in a given genre or form, or all of the works on a particular subject)? as stated previously, i am not yet ready to answer these questions. i hope to find answers in the course of developing the rules and the model. in this paper, i am focusing on raising the questions about the suitability of rdf to our data that have come up in the course of my work. n other relevant projects other relevant projects include the following: 1. frbr, functional requirements for authority data (frad), funtional requirements for subject authority records (frsar), and frbr-objectoriented (frbroo). all are attempts to create conceptual models of bibliographic entities using an entity-relationship model that is very similar to the class-property model used by rdf.2 2. various initiatives at the library of congress (lc), such as lc subject headings (lcsh) in skos,3 the lc name authority file in skos,4 the lccn permalink project to create persistent uris for bibliographic records,5 and initiatives to provide skos representations for vocabularies and data elements used in marc, premis, and mets. these all represent attempts to convert our existing bibliographic data into uris that stand for the bibliographic entities represented by bibliographic records and authority records; the uris would then be available for experiments in putting our data directly onto the semantic web. 3. the dc-rda task group project to put rda data elements into rdf.6 as noted previously and discussed further later, rda is less frbrized than my cataloging rules, but otherwise this project is very similar to mine. 4. dublin core’s (dc’s) work on an rdf schema.7 dublin core is very focused on manifestation and does not deal with expressions and works, so it is less similar to my project than is the dc-rda task groups’s project (see further discussion later). n why my project? one might legitimately ask why there is a need for a different model than the ones already provided by frbr, frad, frsar, frbroo, rda, and dc. the frbr and rda models are still tied to the model that is implicit in our current bibliographic data in which expression and manifestation are undifferentiated. this is because publishers publish and libraries acquire and shelve manifestations. in our current bibliographic practice, a new 58 information technology and libraries | june 2009 bibliographic record is made for either a new manifestation or a new expression. thus, in effect, there is no way for a computer to tell one from the other in our current data. despite the fact that frbr has good definitions of expression (change in content) and manifestation (mere change in carrier), it perpetuates the existing implicit model in its mapping of attributes to entities. for example, frbr maps the following to manifestation: edition statements (“2nd rev. ed.”); statements of responsibility that identify translators, editors, and illustrators; physical description statements that identify illustrated editions; and extent statements that differentiate expressions (the 102-minute version vs. the 89-minute version); etc. thus the frbr definition of expression recognizes that a 2nd revised edition is a new expression, but frbr maps the edition statement to manifestation. in my model, i have tried to differentiate more cleanly data applying to expressions from data applying to manifestations.8 frbr and rda tend to assume that our current bibliographic data elements map to one and only one group 1 entity or class. there are exceptions, such as title, which frbr and rda define at work, expression, and manifestation levels. however, there is a lack of recognition that, to create an accurate model of the bibliographic universe, more data elements need to be applied at the work and expression level in addition to (or even instead of) the manifestation level. in the appendix i have tried to contrast the frbr, frad, and rda models with mine. in my model, many more data elements (properties and attributes) are linked to the work and expression level. after all, if the expression entity is defined as any change in work content, the work entity needs to be associated with all content elements that might change, such as the original extent of the work, the original statement of responsibility, whether illustrations were originally present, whether color was originally present in a visual work, whether sound was originally present in an audiovisual work, the original aspect ratio of a moving image work, and so on. frbr also tends to assume that our current data elements map to one and only one entity. in working on my model, i have come to the conclusion that this is not necessarily true. in some cases, a data element pertaining to a manifestation also pertains to the expression and the work. in other cases, the same data element is specific to that manifestation, and, in other cases, the same data element is specific to its expression. this is true of most of the elements of the bibliographic description. frad, in attempting to deal with the fact that our current cataloging rules allow a single person to have several bibliographic identities (or pseudonyms), treats person, name, and controlled access point as three separate entities or classes. i have tried to keep my model simpler and more elegant by treating only person as an entity, with preferred name and variant name as attributes or properties of that entity. frbroo is focused on the creation process for works, with special attention to the creation of unique works of art and other one-off items found in museums. thus frbroo tends to neglect the collocation of the various expressions that develop in the history of a work that is reproduced and published, such as translations, abridged editions, editions with commentary, etc. dc has concentrated exclusively on the description of manifestations and has neglected expression and work altogether. one of the tenets of semantic web development is that, once an entity is defined by a community, other communities can reuse that entity without defining it themselves. the very different definitions of the work and expression entities in the different communities described above raise some serious questions about the viability of this tenet. n assumptions it should be noted that this entire experiment is based on two assumptions about the future of human intervention for information organization. these two assumptions are based on the even bigger assumption that, even though the internet seems to be an economy based on free intellectual labor, and, even though human intervention for information organization is expensive (and therefore at more risk than ever), human intervention for information organization is worth the expense. n assumption 1: what we need is not artificial intelligence, but a better human–machine partnership such that humans can do all of the intellectual labor and machines can do all of the repetitive clerical labor. currently, catalogers spend too much time on the latter because of the poor design of current systems for inputting data. the universal employment provided by paying humans to do the intellectual labor of building the semantic web might be just the stimulus our economy needs. n assumption 2: those who need structured and granular data—and the precise retrieval that results from it—to carry out research and scholarship may constitute an elite minority rather than most of the people of the world (sadly), but that talented and intelligent minority is an important one for the cultural and technological advancement of humanity. it is even possible that, if we did a better job of providing access to such data, we might enable the enlargement of that minority. can bibliographic data be put directly onto the semantic web? | yee 59 n granularity and structure issues as soon as one starts to create a data model, one encounters granularity or cataloger-data parsing issues. these issues have actually been with us all along as we developed the data model implicit in aacr2r and marc 21. those familiar with rda, frbr, and frad development will recognize that much of that development is directed at increasing structure and granularity in catalogerproduced data to prepare for moving it onto the semantic web. however, there are clear trade-offs in an increase in structure and granularity. more structure and more granularity make possible more powerful indexing and more sophisticated display, but more structure and more granularity are more complex and expensive to apply and less likely to be implemented in a standard fashion across all communities; that is, it is less likely that interoperable data would be produced. any switching or mapping that was employed to create interoperable data would produce the lowest common denominator (the simplest and least granular data), and once rendered interoperable, it would not be possible for that data to swim back upstream to regain its lost granularity. data with less structure and less granularity could be easier and cheaper to apply and might have the potential to be adopted in a more standard fashion across all communities, but that data would limit the degree to which powerful indexing and sophisticated display would be possible. take the example of a personal name: currently, we demarcate surname from forename by putting the surname first, followed by a comma and then the forename. even that amount of granularity can sometimes pose a problem for a cataloger who does not necessarily know which part of the name is surname and which part is forename in a culture unfamiliar to the cataloger. in other words, the more granularity you desire in your data, the more often the people collecting the data are going to encounter ambiguous situations. another example: currently, we do not collect information about gender self-identification; if we were to increase the granularity of our data to gather that information, we would surely encounter situations in which the cataloger would not necessarily know if a given creator was self-defined as a female or a male or of some other gender identity. presently, if we are adding a birth and death date, whatever dates we use are all together in a $d subfield without any separate coding to indicate which date is the birth date and which is the death date (although an occasional “b.” or “d.” will tell us this kind of information). we could certainly provide more granularity for dates, but that would make the marc 21 format much more complex and difficult to learn. people who dislike the marc 21 format already argue that it is too granular and therefore requires too much of a learning curve before people can use it. for example, tennant claims that “there are only two kinds of people who believe themselves able to read a marc record without referring to a stack of manuals: a handful of our top catalogers and those on serious drugs.”9 how much of the granularity already in marc 21 is used either in existing records or, even if present, is used in indexing and display software? granularity costs money, and libraries and archives are already starving for resources. granularity can only be provided by people, and people are expensive. granularity and structure also exist in tension with each other. more granularity can lead to less structure (or more complexity to retain structure along with granularity). in the pursuit of more granularity of data than we have now, rda, attempting to support rdf–compliant xml encoding, has been atomizing data to make it useful to computers, but this will not necessarily make the data more useful to humans. to be useful to humans, it must be possible to group and arrange (sort) the data meaningfully, both for indexing and for display. the developers of skos refer to the “vast amounts of unstructured (i.e., human readable) information in the web,”10 yet labeling bits of data as to type and recording semantic relationships in a machine-actionable way do not necessarily provide the kind of structure necessary to make data readable by humans and therefore useful to the people the web is ultimately supposed to serve. consider the case of music instrumentation. if you have a piece of music for five guitars and one flute, and you simply code number and instrumentation without any way to link “five” with “guitars” and “one” with “flute,” you will not be able to guarantee that a person looking for music for five flutes and one guitar will not be given this piece of music in their results (see figure 1).11 the more granular the data, the less the cataloger can build order, sequencing, and linking into the data; the coding must be carefully designed to allow the desired order, sequencing, and linking for indexing and display to be possible, which might call for even more complex coding. it would be easy to lose information about order, sequencing, and linking inadvertently. actually, there are several different meanings for the term structure: 1. structure is an object of a record (structure of document?); for example, elings and waibel refer to “data fields . . . also referred to as elements . . . which are organized into a record by a data structure.”12 2. structure is the communications layer, as opposed to the display layer or content designation.13 3. structure is the record, field, and subfield. 4. structure is the linking of bits of data together in the 60 information technology and libraries | june 2009 form of various types of relationships. 5. structure is the display of data in a structured, ordered, and sequenced manner to facilitate human understanding. 6. data structure is a way of storing data in a computer so that it can be used efficiently (this is how computer programmers use the term). i hasten to add that i am definitely in favor of adding more structure and granularity to our data when it is necessary to carry out the fundamental objectives of our profession and of our catalogs. i argued earlier that frbr and rda are not granular enough when it comes to the distinction between data elements that apply to expression and those that apply to manifestation. if we could just agree on how to differentiate data applying to the manifestation from data applying to the expression instead of our current practice of identifying works with headings and lumping all manifestation and expression data together, we could increase the level of service we are able to provide to users a thousandfold. however, if we are not going to commit to differentiating between figure 1b. example of encoding of musical

blank node to group repeated number and instrument type) can bibliographic data be put directly onto the semantic web? | yee 61 expression and manifestation, it would be more intellectually honest for frbr and rda to take the less granular path of mapping all existing bibliographic data to manifestation and expression undifferentiated, that is, to use our current data model unchanged and state this openly. i am not in favor of adding granularity for granularity’s sake or for the sake of vague conceptions of possible future use. granularity is expensive and should be used only in support of clear and fundamental objectives. n the goal: efficient displays and indexes my main concern is that we model and then structure the data in a way that allows us to build the complex displays that are necessary to make catalogs appear simple to use. i am aware that the current orthodoxy is that recording data should be kept completely separate from indexing and display (“the applications layer”). because i have spent my career in a field in which catalog records are indexed and displayed badly by systems people who don’t seem to understand the data contained in them, i am a skeptic. it is definitely possible to model and structure data in such a way that desired displays and indexes are impossible to construct. i have seen it happen! the lc working group report states that “it will be recognized that human users and their needs for display and discovery do not represent the only use of bibliographic metadata; instead, to an increasing degree, machine applications are their primary users.”14 my fear is that the underlying assumption here is that users need to (and can) retrieve the single perfect record. this will never be true for bibliographic metadata. users will always need to assemble all relevant records (of all kinds) as precisely as possible and then browse through them before making a decision about which resources to obtain. this is as true in the semantic web—where “records” can be conceived of as entity or class uris—as it is in the world of marc–encoded metadata. some of the problems that have arisen in the past in trying to index bibliographic metadata for humans are connected to the fact that existing systems do not group all of the data related to a particular entity effectively, such that a user can use any variant name or any combination of variant names for an entity and do a successful search. currently, you can only look for a match among two or more keywords within the bounds of a single manifestation-based bibliographic record or within the bounds of a single heading, minus any variant terms for that entity. thus, when you do a keyword search for two keywords, for example, “clemens” and “adventures,” you will retrieve only those manifestations of mark twain’s adventures of tom sawyer that have his real name (clemens) and the title word “adventures” co-occurring within the bounded space created by a single manifestation-based bibliographic record. instead, the preferred forms and the variant forms for a given entity need to be bounded for indexing such that the keywords the user employs to search for that entity can be matched using co-occurrence rules that look for matches within a single bounded space representing the entity desired. we will return to this problem in the discussion of issue 3 in the later section “rdf problems encountered.” the most complex indexing problem has always proven to be the grouping or bounding of data related to a work, since it requires pulling in all variants for the creator(s) of that work as well. otherwise, a user who searches for a work using a variant of the author’s name and a variant of the title will continue to fail (as they do in all current opacs), even when the desired work exists in the catalog. if we could create a uri for the adventures of tom sawyer that included all variant names for the author and all variant titles for the work (including the variant title tom sawyer), the same keyword search described above (“clemens” and “adventures”) could be made to retrieve all manifestations and expressions of the adventures of tom sawyer, instead of the few isolated manifestations that it would retrieve in current catalogs. we need to make sure that we design and structure the data such that the following displays are possible: n display all works by this author in alphabetical order by title with the sorting element (title) appearing at the top of each work displayed. n display all works on this subject in alphabetical order by principal author and title (with principal author and title appearing at top of each work displayed), or title if there is no principal author (with title appearing at top of each work displayed). we must ensure that we design and structure the data in such a way that our structure allows us to create subgroups of related data, such as instrumentation for a piece of music (consisting of a number associated with each particular instrument), place and related publisher for a certain span of dates on a serial title change record, and the like. n which standards will carry out which functions? currently, we have a number of different standards to carry out a number of different functions; we can speculate about how those functions might be allocated in a new semantic web–based dispensation, as shown in table 1. in table 1, data structure is taken to mean what a record represents or stands for; traditionally, a record has represented an expression (in the days of hand62 information technology and libraries | june 2009 press books) or a manifestation (ever since reproduction mechanisms have become more sophisticated, allowing an explosion of reproductions of the same content in different formats and coming from different distributors). rda is record-neutral; rdf would allow uris to be established for any and all of the frbr levels; that is, there would be a uri for a particular work, a uri for a particular expression, a uri for a particular manifestation, and a uri for a particular item. note that i am not using data structure in the sense that a computer programmer does (as a way of storing data in a computer so that it can be used efficiently). currently, the encoding of facts about entity relationships (see table 1) is carried out by matching data-value character strings (headings or linking fields using issns and the like) that are defined by the lc/naco authority file (following aacr2r rules), lcsh (following rules in the subject cataloging manual), etc. in the future, this function might be carried out by using rdf to link the uri for a resource to the uri for a data value. display rules (see table 1) are currently defined by isbd and aacr2r but widely ignored by systems, which frequently truncate bibliographic records arbitrarily in displays, supply labels, and the like; rda abdicates responsibility, pushing display out of the cataloging rules. the general principle on the web is to divorce data from display and allow anyone to display the data any way they want. display is the heart of the objects (or goals) of cataloging: the point is to display to the user the works of an author, the editions of a work, or the works on a subject. all of these goals only can be met if complex, high-quality displays can be built from the data created according to the data model. indexing rules (see table 1) were once under the control of catalogers (in book and card catalogs) in that users had to navigate through headings and cross-references to find table 1. possible reallocation of current functions in a new semantic web–based dispensation function current future? data content, or content

they wanted; currently indexing is in the hands of system designers who prefer to provide keyword indexing of bibliographic (i.e., manifestation-based) records rather than provide users with access to the entities they are really interested in (works, authors and subjects), all represented currently by authority records for headings and cross-references. rda abdicates responsibility, pushing indexing concerns completely out of the cataloging rules. the general principle on the web is to allow resources to be indexed by any web search engines that wish to index them. current web data is not structured at all for either indexing or display. i would argue that our interest in the semantic web should be focused on whether or not it will support more data structure—as well as more logic in that data structure—to support better indexes and better displays than we have now in manifestation-based ils opacs. crucial to better indexing than we have ever had before are the co-occurrence rules for keyword indexing, that is, the rules for when a co-occurrence of two or more keywords should produce a match. we need to be able to do a keyword search across all possible variant names for the entity of interest, and the entity of interest for the average catalog user is much more likely to be a particular work than to be a particular manifestation. unfortunately, catalog-use studies only have studied so-called known-item searches without investigating whether a known-item searcher was looking for a particular edition or manifestation of a work or was simply looking for a particular work in order to make a choice as to edition or manifestation once the work was found. however, common sense tells us that it is a rare user who approaches the catalog with prior knowledge about all published editions of a given work. the more common situation is surely one in which a user desires to read a particular shakespeare play or view a particular david lean film and discovers that the desired work exists in more than one expression or manifestation only after searching the catalog. we need to have the keyword(s) in our search for a particular work co-occur within a bounded space that encompasses all possible keywords that might refer to that particular work entity, including both creator and title keywords. notice in table 1 the unifying effect that rdf could potentially have; it could free us from the use of multiple standards that can easily contradict each other, or at least not live peacefully together. examples are not hard to find in the current environment. one that has cropped up in the course of rda development concerns family names. presently the rules for naming families are different depending on whether the family is the subject of a work (and established according to lcsh) or whether the family is responsible for a collection of papers (and established according to rda). n types of data rda has blurred the distinctions among certain types of data, apparently because there is a perception that on the semantic web the same piece of data needs to be coded only once, and all indexing and display needs can be supported from that one piece of data. i question that assumption on the basis of my experience with bibliographic cataloging. all of the following ways of encoding the same piece of data can still have value in certain circumstances: n transcribed; in rdf terms, a literal (i.e., any data that is not a uri, a constant value). transcribed data is data copied from an item being cataloged. it is valuable for providing access to the form of the name used on a title page and is particularly useful for people who use pseudonyms, corporate bodies that change name, and so on. transcribed data is an important part of the historical record and not just for off-line materials; it can be a historical record of changing data on notoriously fluid webpages. n composed; in rdf terms, also a literal. composed data is information composed by a cataloger on the basis of observation of the item in hand; it can be valuable for historical purposes to know which data was composed. n supplied; in rdf terms, also a literal. supplied data is information supplied by a cataloger from outside sources; it can be valuable for historical purposes to know which data was supplied and from which outside sources it came. n coded; in rdf, represented by a uri. coded data would likely transform on the semantic web into links to ontologies that could provide normalized, human-readable identification strings on demand, thus causing coded and normalized data to merge into one type of data. is it not possible, though, that the coded form of normalized data might continue to provide for more efficient searching for computers as opposed to humans? coded data also has great cross-cultural value, since it is not as language-dependent as literals or normalized headings. n normalized headings (controlled headings); in rdf, represented by a uri. normalized or controlled headings are still necessary to provide users with coherent, ordered displays of thousands of entities that all match the user’s search for a particular entity (work, author, subject, etc.). the reason google displays are so hideous is that, so far, the data searched lacks any normalized display data. if variant language forms of the name for an entity 64 information technology and libraries | june 2009 are linked to an entity uri, it should be possible to supply headings in the language and script desired by a particular user. n the rdf model those who have become familiar with frbr over the years will probably not find it too difficult to transition from the frbr conceptual model to the rdf model. what frbr calls an “entity,” rdf calls a “subject” and rdfs calls a “class.” what frbr calls an “attribute,” rdf calls an “object” and rdfs calls a “property.” what frbr calls a “relationship,” rdf calls a “predicate” and rdfs calls a “relationship” or a “semantic linkage” (see table 2). the difficulty in any data-modeling exercise lies in deciding what to treat as an entity or class and what to treat as an attribute or property. the authors of frbr decided to create a class called expression to deal with any change in the content of a work. when frbr is applied to serials, which change content with every issue, the model does not work well. in my model, i found it useful to create a new entity at the manifestation level, the serial title, to deal with the type of change that is more relevant to serials, the change in title. i also created another new entity at the manifestation level, title-manifestation, to deal with a change of title in a nonserial work that is not associated with a change in content. one hundred years ago, this entity would have been called title-edition. i am also in the process of developing an entity at the expression level—surrogate—to deal with reproductions of original artworks that need to inherit the qualities of the original artwork they reproduce without being treated as an edition of that original artwork, which ipso facto is unique. these are just examples of cases in which it is not that easy to decide on the classes or entities that are necessary to accurately model bibliographic information. see the appendix for a complete comparison of the classes and entities defined in four different models: frbr, frad, rda, and the yee cataloging rules (ycr). the appendix also shows variation among these models concerning whether a given data element is treated as a class/entity or as an attribute/property. the most notable examples are name and preferred access point, which are treated as classes/entities in frad, as attributes in frbr and ycr, and as both in rda. n rdf problems encountered my goal for this paper is to institute discussion with data modelers about which problems i observed are insoluble and which are soluble: 1. is there an assumption on the part of semantic web developers that a given data element, such as a publisher name, should be expressed as either a literal or using a uri (i.e., controlled), but never both? cataloging is rooted in humanistic practices that require careful recording of evidence. there will always be value in distinguishing and labeling the following types of data: n copied as is from an artifact (transcribed) n supplied by a cataloger n categorized by a cataloger (controlled) tim berners-lee (the father of the internet and the semantic web) emphasizes the importance of recording not just data but also its provenance for the sake of authenticity.15 for many data elements, therefore, it will be important to be able to record both a literal (transcribed or composed form or both) and a uri (controlled form). is this a problem in rdf? as a corollary, if any data that can be given a uri cannot also be represented by a literal (transcribed and composed data, or one or the other), it may not be possible to design coherent, readable displays of the data describing a particular entity. among other things, cataloging is a discursive writing skill. does rdf require that all data be represented only once, either by a literal or by a uri? or is it perhaps possible that data that has a uri could also have a transcribed or composed form as a property? perhaps it will even be possible to store multiple snapshots of online works that change over time to document variant forms of a name for works, persons, and so on. 2. will the internet ever be fast enough to assemble the equivalent of our current records from a collection of hundreds or even thousands of uris? in rdf, links are one-to-one rather than one-to-many. this leads to a great proliferation of reciprocal links. the more granularity there is in the data, the more linking is necessary to ensure that atomized data elements are linked together. potentially, every piece of data describing a particular entity could be represented by a uri leading out to a skos list of data values. the number of links necessary to pull together table 2. the frbr conceptual model translated into rdf and rdfs frbr rdf rdfs entity subject class attribute object property relationship predicate relationship/ semantic linkage can bibliographic data be put directly onto the semantic web? | yee 65 all of the data just to describe one manifestation could become astronomical, as could the number of one-to-one links necessary to create the appearance of a one-to-many link, such as the link between an author and all the works of an author. is the internet really fast enough to assemble a record from hundreds of uris in a reasonable amount of time? given the often slow network throughput typical of many of our current internet connections, is it really practical to expect all of these pieces to be pulled together efficiently to create a single display for a single user? we yet may feel nostalgia for the single manifestation-based record that already has all of the relevant data in it (no assembly required). bruce d’arcus points out, however, that i think if you’re dealing with rdf, you wouldn’t necessarily be gathering these data in real-time. the uris that are the targets for those links are really just global identifiers. how you get the triples is a separate matter. so, for example, in my own personal case, i’m going to put together an rdf store that is populated with data from a variety of sources, but that data population will happen by script, and i’ll still be querying a single endpoint, where the rdf is stored in a relational database.16 in other words, d’arcus essentially will put them all in one place, or in one database that “looks” from a uri perspective to be “one place” where they’re already gathered. 3. is rdf capable of dealing with works that are identified using their creators? we need to treat author as both an entity in its own right and as a property of a work, and in many cases the latter is the more important function for user service. lexical labels, or human-readable identifiers for works that are identified using both the principal author and the title, are particularly problematic in rdf given that the principal author is an entity in its own right. is rdf capable of supporting the indexing necessary to allow a user to search using any variant of the author’s name and any variant of the title of a work in combination and still retrieve all expressions and manifestations of that work, given that author will have a uri of its own, linked by means of a relationship link to the work uri? is rdf capable of supporting the display of a list of one thousand works, each identified by principal author, in order first by principal author, then by title, then by publication date, given that the preferred heading for each principal author would have to be assembled from the uri for that principal author and the preferred title for each work would have to be assembled from the uri for that work? for fear that this will not, in fact, be possible, i have put a human-readable work-identifier data element into my model that consists of principal author and title when appropriate, even though that means the preferred name of the principal author may not be able to be controlled by the entity record for the principal author. any guidance from experienced data modelers in this regard would be appreciated. according to bruce d’arcus, this is purely an interface or application question that does not require a solution at the data layer.17 since we have never had interfaces or applications that would do this correctly, even though the data is readily available in authority records, i am skeptical about this answer! perhaps bruce’s suggestion under item 9 of designating a sortname property for each entity is the solution here as well. my human-readable work identifier consisting of the name of the principal creator and uniform title of work could be designated the sortname poperty for the work. it would have to be changed whenever the preferred form of the name for the principal creator changed, however. 4. do all possible inverse relationships need to be expressed explicitly, or can they be inferred? my model is already quite large, and i have not yet defined the inverse of every property as i really should to have a correct rdf model. in other words, for every property there needs to be an inverse property; for example, the property iscreatorof needs to have the inverse property iscreatedby; thus “twain” has the property iscreatorof, while “adventures of tom sawyer” has the property iscreatedby. perhaps users and inputters will not actually have to see the huge, complex rdf data model that would result from creating all the inverse relationships, but those who maintain the model will have to deal with a great deal of complexity. however, since i’m not a programmer, i don’t know how the complexity of rdf compares to the complexity of existing ils software. 5. can rdf solve the problems we are having now because of the lack of transitivity or inheritance in the data models that underlie current ilses, or will rdf merely perpetuate these problems? we have problems now with the data models that underlie our current ilses because of the inability of these models to deal with hierarchical inheritance, such that whatever is true of an entity in the hierarchy is also true of every entity below that entity in the hierarchy. one example is that of cross-references to a parent corporate body that should be held to apply to all subdivisions of that corporate body but never are in existing ils systems. there is a cross-reference from “fbi” to “united states. federal bureau of investigation,” but not from “fbi counterterrorism division” to “united states. federal bureau of investigation. counterterrorism division.” for that reason, a search in any opac name index for “fbi counterterrorism division” will fail. we need systems that recognize that data about a parent corporate body is relevant to all subdivisions of that parent body. we need systems that recognize that data about a work is relevant to all expressions and manifestations of that work. rdf allows you to link a work to an expression 66 information technology and libraries | june 2009 and an expression to a manifestation, but i don’t believe it allows you to encode the information that everything that is true of the work is true of all of its expressions and manifestations. rob styles seems to confirm this: “rdf doesn’t have hierarchy. in computer science terms, it’s a graph, not a tree, which means you can connect anything to anything else in any direction.”18 of course, not all links should be this kind of transitive or inheritance link. one expression of work a is linked to another expression of work a by links to work a, but whatever is true of one of those expressions is not necessarily true of the other; one may be illustrated, for example, while the other is not. whatever is true of one work is not necessarily true of another work related to it by related work link. it should be recognized that bibliographic data is rife with hierarchy. it is one of our major tools for expressing meaning to our users. corporate bodies have corporate subdivisions, and many things that are true for the parent body also are true for its subdivisions. subjects are expressed using main headings and subject subdivisions, and many things that are true for the main heading (such as variant names) also are true for the heading combined with one of its subdivisions. geographic areas are contained within larger geographic areas, and many things that are true of the larger geographic area also are true for smaller regions, counties, cities, etc., contained within that larger geographic area. for all these reasons, i believe that, to do effective displays and indexes for our bibliographic data, it is critical that we be able to distinguish between a hierarchical relationship and a nonhierarchical relationship. 6. to recognize the fact that the subject of a book or a film could be a work, a person, a concept, an object, an event, or a place (all classes in the model), is there any reason we cannot define subject itself as a property (a relationship) rather than a class in its own right? in my model, all subject properties are defined as having a domain of resource, meaning there is no constraint as to the class to which these subject properties apply. i’m not sure if there will be any fall-out from that modeling decision. 7. how do we distinguish between the corporate behavior of a jurisdiction and the subject behavior of a geographical location? sometimes a place is a jurisdiction and behaves like a corporate body (e.g., united states is the name of the government of the united states). sometimes place is a physical location in which something is located (e.g., the birds discussed in a book about the birds of the united states). to distinguish between the corporate behavior of a jurisdiction and the subject behavior of a geographical location, i have defined two different classes for place: place as jurisdictional corporate body and place as geographic area. will this cause problems in the model? will there be times when it prevents us from making elegant generalizations in the model about place per se? there is a similar problem with events. some events are corporate bodies (e.g., conferences that publish papers) and some are a kind of subject (e.g., an earthquake). i have defined two different classes for event: conference or other event as corporate body creator and event as subject. 8. what is the best way to model a bound-with or an issuedwith relationship, or a part–whole relationship in which the whole must be located to obtain the part? the bound-with relationship is actually between two items containing two different works, while the issued-with relationship is between two manifestations containing two different works (see figure 2). is this a work-to-work relationship? will designating it a work-to-work relationship cause problems for indicating which specific items or manifestation-items of each work are physically located in the same place? this question may also apply to those part–whole relationships in which the part is physically contained within the whole and both are located in the same place (sometimes known as analytics). one thing to bear in mind is that in all of these cases the relationship between two works does not hold between all instances of each work; it only holds for those particular instances that are contained in the particular manifestation or item that is bound with, issued with, or part of the whole. however, if the relationship is modeled as a work-1manifestation to work-2-manifestation relationship, or a work-1-item to work-2-item relationship,, care must be taken in the design of displays to pull in enough information about the two or more works so as not to confuse the user. 9. how do we express the arrangement of elements that have a definite order? i am having trouble imagining how to encode the ordering of data elements that make up a larger element, such as the pieces of a personal name. this is really a desire to control the display of those atomized elements so that they make sense to human beings rather than just to machines. could one define a property such as natural language order of forename, surname, middle name, patronymic, matronymic and/or clan name of a person given that the ideal order of these elements might vary from one person to another? could one define properties such as sorting element 1, sorting element 2, sorting element 3, etc., and assign them to the various pieces that will be assembled to make a particular heading for an entity, such as an lcsh heading for a historical period? (depending on the answer to the question in item 11, it may or may not be possible to assign a property to a property in this fashion.) are there standard sorting rules we need to be aware of (in unicode, for example)? are there other rdf techniques available to deal with sorting and arrangement? bruce d’arcus suggests that, instead of coding the name parts, it would be more useful to designate sortname properties;19 might it not be necessary to designate a sortname property for each variant name, as well, can bibliographic data be put directly onto the semantic web? | yee 67 for cases in which variants need to appear in sorted displays? and wouldn’t these sortname properties complicate maintenance over time as preferred and variant names changed? 10. how do we link related data elements in such a way that effective indexing and displays are possible? some examples: number and kind of instrument (e.g., music written for two oboes and three guitars); multiple publishers, frequencies, subtitles, editors, etc., with date spans for a serial title change (or will it be necessary to create a new manifestation for every single change in subtitle, publisher name, place of publication, etc?). the assumption seems to be that there will be no repeatable data elements. based on my somewhat limited experience with rdf, it appears that there are record equivalents (every data element—property or relationship—pertaining to a particular entity with a uri), but there are no field or subfield equivalents that allow the sublinking of related pieces of data about an entity. indeed, rob styles goes so far as to argue that ultimately there is no notion of a “record” in rdf.20 it is possible that blank nodes might be able to fill in for fields and subfields in some cases for grouping data, but there are dangers involved in their use.21 to a cataloger, it looks as though the plan is for rdf data to float around loose without any requirement that there be a method for pulling it together into coherent displays designed for human beings. 11. can a property have a property in rdf? as an example of where it might be useful to define a property of a property, robert maxwell suggests that date of publication is really an attribute (property) of the published by relationship (another property).22 another example: in my model, a variant title for a serial is a property. can that property itself have the property type of variant title to encompass things like spine title, key title, etc.? another example appeared in item 9, in which it is suggested that it might be desirable to assign sort-element properties to the various elements of a name property. 12. how do we document record display decisions? there is no way to record display decisions in rdf itself; it is completely display-neutral. we could not safely commit to a particular rdf–based data model until a significant amount of sample bibliographic data had been created and open-source indexing and display software had been designed and user-tested on that data. it may be that we will need to supplement rdf with some other encoding mechanism that allows us to record display decisions along with the data. current cataloging rules are about display as much as they are about content designation. isbd concerns the order in which the elements should be displayed to humans. the cataloging objectives concern display to users of such entity groups as the works of an author, the editions of a work, and the works on a subject. 13. can all bibliographic data be reduced to either a class or a property with a finite list of values? another way to put this is to ask if all that catalogers do could be reduced to a set of pull-down menus. cataloging is the art of writing discursive prose as much as it is the ability to select the correct value for a particular data element. we must deal with ambiguous data (presented by joe blow could mean that joe created the entire work, produced it, distributed it, sponsored it, or merely funded it). we must sometimes record information without knowing its exact meaning. we must deal with situations that have not been anticipated in advance. it is not possible to list every possible kind of data and every possible value for each type of figure 2. examples of part–whole relationships. how might these be best expressed in rdf? issued-with relationship a copy of charlie chaplin’s 1917 film the immigrant can be found on a videodisc compilation called charlie chaplin, the early years along with two other chaplin films. this compilation was published and collected by many different libraries and media centers. if a user wants to view this copy of the immigrant, he or she will first have to locate charlie chaplin, the early years, then look for the desired film at the beginning of the first videodisc in the set. the issued-with relationship between the immigrant and the other two films on charlie chaplin, the early years is currently expressed in the bibliographic record by means of a “with” note: first on charlie chaplin, the early years, v. 1 (62 min.) with: the count – easy street. bound-with relationship the university of california, los angeles film & television archive has acquired a reel of 16 mm. film from a collector who strung five warner bros. cartoons together on a single reel of film. we can assume that no other archive, library, or media collection will have this particular compilation of cartoons, so the relationship between the five cartoons is purely local in nature. however, any user at the film & television archive who wishes to view one of these cartoons will have to request a viewing appointment for the entire reel and then find the desired cartoon among the other four on the reel. the bound-with relationship among these cartoons is currently expressed in a holdings record by means of a “with” note: fourth on reel with: daffy doodles – tweety pie – i love to singa – along flirtation walk. 68 information technology and libraries | june 2009 data up front before any data is gathered. it will always be necessary to provide a plain-text escape hatch. the bibliographic world is a complex, constantly changing world filled with ambiguity. n what are the next steps? in a sense, this paper is a first crude attempt at locating unmapped territory that has not yet been explored. if we were to decide as a community that it would be valuable to move our shared cataloging activities onto the semantic web, we would have a lot of work ahead of us. if some of the rdf problems described above are insoluble, we may need to work with semantic web developers to create a more sophisticated version of rdf that can handle the transitivity and complex linking required by our data. we will also need to encourage a very complex existing community to evolve institutional structures that would enable a more efficient use of the internet for the sharing of cataloging and other metadata creation. this is not just a technological problem, but also a political one. in the meantime, the experiment continues. let the thinking and learning begin! references and notes 1. “notation3, or n3 as it is more commonly known, is a shorthand non–xml serialization of resource description framework models, designed with human-readability in mind: n3 is much more compact and readable than xml rdf notation. the format is being developed by tim berners-lee and others from the semantic web community.” wikipedia, “notation 3,” http://en.wikipedia.org/wiki/notation_3 (accessed feb. 19, 2009). 2. frbr review group, www.ifla.org/vii/s13/wgfrbr/; frbr review group, franar (working group on functional requirements and numbering of authority records), www .ifla.org/vii/d4/wg-franar.htm; frbr review group, frsar (working group, functional requirements for subject authority records), www.ifla.org/vii/s29/wgfrsar.htm; frbroo, frbr review group, working group on frbr/crm dialogue, www .ifla.org/vii/s13/wgfrbr/frbr-crmdialogue_wg.htm. 3. library of congress, response to on the record: report of the library of congress working group on the future of bibliographic control (washington, d.c.: library of congress, 2008): 24, 39, 40, www.loc.gov/bibliographic-future/news/lcwgrpt response_dm_053008.pdf (accessed mar. 25, 2009). 4. ibid., 39. 5. ibid., 41. 6. dublin core metadata initiative, dcmi/rda task group wiki, http://www.dublincore.org/dcmirdataskgroup/ (accessed mar. 25, 2009). 7. mikael nilsson, andy powell, pete johnston, and ambjorn naeve, expressing dublin core metadata using the resource description framework (rdf), http://dublincore.org/ documents/2008/01/14/dc-rdf/ (accessed mar. 25, 2009). 8. see for example table 6.3 in frbr, which maps to manifestation every kind of data that pertains to expression change with the exception of language change. ifla study group on the functional requirements for bibliographic records, functional requirements for bibliographic records (munich: k. g. saur, 1998): 95, http://www.ifla.org/vii/s13/frbr/frbr.pdf (accessed mar. 4, 2009). 9. roy tennant, “marc must die,” library journal 127, no. 17 (oct. 15, 2002): 26. 10. w3c, skos simple knowledge organization system reference, w3c working draft 29 august 2008, http://www.w3.org/ tr/skos-reference/ (accessed mar. 25, 2009). 11. the extract in figure 1 is taken from my complete rdf model, which can be found at http://myee.bol.ucla.edu/ ycrschemardf.txt. 12. mary w. elings and gunter waibel, “metadata for all: descriptive standards and metadata sharing across libraries, archives and museums,” first monday 12, no. 3 (mar. 5, 2007), http://www.uic.edu/htbin/cgiwrap/bin/ojs/index.php/fm/ article/view/1628/1543 (accessed mar. 25, 2009). 13. oclc, a holdings primer: principles and standards for local holdings records, 2nd ed.

!proceedings of the educom fall conference, october 11-13, 1972, ann arbor, michigan. princeton: educom, 1973. 209p. $6.00. as with so many conferences, the principal beneficiaries of this one are those who attended the sessions, and not those who will read the proceedings. except for a few prepared papers, the text is the somewhat edited version of verbatim, ad lib summaries of a number of workshop sessions and two panels that purport to summarize common themes and consensus. since few people are profound in ad lib commentaries, the result is shallow and repetitive. the forest of themes is completely lost among a bewildering array of trees. the conference was, i am sure, exciting and thought-provoking for the participants. it was simply organized, starting with statements of networking activities in a number of disciplines, i.e., chemistry, language studies, economics, libraries, museums, and social research. the paper on economics is by far the best organized presentation of the problems and potential of computers in any of the fields considered, and perhaps the best short presentation yet published for economics. the paper on libraries was short, that on chemistry lacking in analytical quality, that on language provocative, that on social research highly personal, and that on museums a neat mixture of reporting and interpreting. much of the information is conditional, that is, it described what might or could be in the realm of the application of computers to the various subjects. the speakers all directed their papers to the concept of networks, interpreted chiefly as widespread remote access to computational facilities. the papers are followed by very brief transcripts of the summaries of workshops in which the application of computers to each of the disciplines was presumably discussed in detail. much of each summary is indicative and not really informative about the discussions. the concluding text again is the transcript of two final panels on themes and relationships among computer centers. the only description for this portion of the text is turgid. in the midst of all this is the banquet paper presented by ed parker, who as usual was thoughtful and insightful, and several presentations by national science foundation officials that must have been useful at the time to guide those relying on federal funding for computer networks in developing proposals. i can't think of another reference that touches on the potential of computers in so many different disciplines, but it is apparent from the breadth of ideas and the range of suggested or tested applications that a coherent and analytical review should be done. this volume isn't it. russell shank smithsonian institution the analysis of information systems, by charles t. meadow. second edition. los angeles: melville publishing co., 1973. a wiley-becker & hayes series book. this is a revised edition of a book first published in 1967. the earlier edition was written from the viewpoint of the programmer interested in the application of computers to information retrieval and related problems. the second edition claims to be "more of a textbook for information science graduate students and users" (although it is not clear who these "users" are) . elsewhere the author indicates that his emphasis is on "software technology of information systems" and that the book is intended "to bridge the communications gap among information users, librarians and data processors." the book is divided into four parts: language and communication (dealing largely with indexing techniques and the properties of index languages) , retrieval of information (including retrieval strategies and the evaluation of system performance), the organization of information (organization of records, of ffies, file sets), computer processing of information (basic file processes, data access systems, interactive information retrieval, programming languages, generalized data management systems). the second two sections are, i feel, . much better than the first. these are the areas in which the author has had the most direct experience, and the topics covered, at least in their information retrieval applications, are not discussed particularly well or particularly fully elsewhere. it is these sections of the book that make it of most value to the student of information science. i am less happy about meadow's discussion of indexing and index languages, which i find unclear, incomplete, and inaccurate in places. the distinction drawn between pre-coordinate and post-coordinate systems is inaccurate; meadow tends to refer to such systems simply as keyword systems, although it is perfectly possible to have a post-coordinate system based on, say, class numbers, which can hardly be considered keywords, while it is also possible to have keyword systems that are essentially precoordinate. in fact, meadow relates the characteristic of being post-coordinate to the number of terms an indexer may use (" ... permit their users to select several descriptors for an index, as many as are needed to describe a particular document"), but this is not an accurate distinction between the two types of system. the real difference is related to how the terms are used (not how many are used), including how they are used at the time of searching. the references to faceted classification are also confusing and a number of statements are made throughout the discussion on index languages that are completely untrue. for example, meadow states (p. 51) that "a hierarchical classification language has no syntax to combine descriptors into terms." this is not at all accurate since several hierarchical classification schemes, including udc, do have synthetic elements which allow combination of descriptors, and some of these are highly synthetic. in fact, meadow himself gives an example (p. 3839) of this synthetic feature in the udc. it is also perhaps unfortunate that the student could read all through meadow's discussion of index languages without getting any clear idea of the structure of a thesaurus for information retrieval and how this thesaurus is applied in practice. book reviews 151 moreover, meadow used medical subject headings as his example of a thesaurus (p. 33-34), although this is not at all a conventional thesaurus and does not follow the usual thesaurus structure. my other criticism is that the book is too selective in its discussion of various aspects of information retrieval. for example, the discussion on automatic indexing is by no means a complete review of techniques that have been used in this field. likewise, the discussion of interactive systems is very limited, because it is based solely on nasa's system, recon. the student who relied only on meadow's coverage of these topics would get a very incomplete and one-sided view of what exists and what has been done in the way of research. in short, i would recommend this book for those sections (p. 183-412) that deal with the organization of records and files and with related programming considerations. the author has handled these topics well and perhaps more completely, in the information retrieval context, than anyone else. indexing and index languages, on the other hand, are subjects that have been covered more completely, clearly, and accurately by various other writers. i would not recommend the discussion on index languages to a student unless read in conjunction with other texts. f. w. lancaster university of illinois application of computer technology to librm·y processes, a syllabus, by joseph becker and josephine s. pulsifer. metuchen, n.j.: scarecrow press, 1973. 173p. $5.00. despite the large number of institutions offering courses related to library automation, including just about every library school in north america, accredited or not, there is a remarkable shortage of published material to assist in this instruction. with the publication of this small volume a light has been kindled; let us hope it will be only the first of many, for larger numbers of better educated librarians must surely result in higher standards in the field. this syllabus covers eight topics related 152 journal of library automation vol. 7/2 jtme 1974 to the use of computers in libraries, titled as follows: bridging the gap (librarians and automation); computer technology; systems analysis and implementation; marc program; library clerical processes (which encompasses acquisitions, cataloging, serials, circulation, and management information) ; reference services; related technologies; and library networks. each topic is treated as a unit of instruction, and each receives the identical treatment as follows. the units each start with an introductory paragraph, explaining what the field encompasses, and indicating the purpose of teaching that topic. the purpose of systems analysis, for example, is "to develop the sequence of steps essential to the introduction of automated systems into the library." a series of behavioral objectives are then listed, to show what the student will be able to do (after he has learned the material) that he presumably was unable to do before. for example, there are seven behavioral objectives in the unit on computer technology, of which the first four are: "1) the student will be able to discuss the two-fold requirement to represent data by codes and data structures for purposes of machine manipulation, 2) the student will be able to identify the basic components of computer systems and describe their purposes, 3) the student will be able to differentiate hardware and software and describe briefly the part that programming plays in the overall computer processing operation, 4) the student will be able to define the various modes of computer operation and indicate the utility of each in library operations." the remaining three objectives refer to the student's ability to enumerate and compare types of input, output, and storage devices. then an outline of the instructional material is presented, followed by the detailed and well-organized material for instruction. in no case can the material presented here be considered all that an instructor would need to know about the field, but a surprising amount of specific detail is included, along with a carefully organized framework within which to place other knowledge. the end result is to present to the instructor a series of outlines that would encompass much of the material included in a basic introductory course in library automation. every instructor would, presumably, want to add other topics of his own in addition to adding other material to the topics treated in this volume, but he has here an extremely helpful guide to a basic course, and the only work of its kind to be published to date. peter simmons school of librarianship university of british columbia the larc reports, vol. 6, issue 1. online cataloging and circulation at western kentucky university: an approach to automated instructional resources ~anagement. 1973. 78p. this is a detailed account of the design, development, and implementation of online cataloging and circulation which have been in operation at western kentucky university for several years. the library's reasons for using computers are similar to those of many college and university libraries that experienced rapid growth during the 1960s. the faculty of the division of library services first prepared a detailed proposal with appropriate feasibility studies and cost analyses to reclassify the collection from dewey decimal to library of congress classification. the proposal was approved by the administration of the university, and the decision was made to utilize campus computer facilities via online input techniques for reclassification, cataloging, and circulation. "project reclass" was accomplished during 1970-71 using ibm 2741 ats/360 terminals. a circulation file was subsequently generated from the master record file. the main library is housed in a new building and has excellent computer facilities within the library that are connected to the university computer center. cataloging information is input directly into the system via ats terminals; ibm 2260 visual display terminals are used for inquiry into the status of books and patrons; and ibm 1031/1033 data collection terminals are used to charge out and check in books. catalog cards and book catalogs in upper/lower case are produced in batch mode on regular schedule. the on-line circulation book record file is used in conjunction with the on-line student master record and payroll master record files for preparation of overdue and fine notices. apparently the communication between library staff and computer personnel has been well above average, and cooperation of the administration and other interested parties has been outstanding. the attention given to planning, scheduling, training, and implementation is impressive. what has been accomplished to date is considered very successful, and plans are book reviews 153 underway to develop on-line acquisitions ordering and receiving procedures. the report has some annoying shortcomings such as referring to the library of congress as "national library"; frequent use of the word "xeroxing," which the xerox corporation is attempting to correct; "inputing" for "inputting"; and several other misspelled words. some parts are poorly organized and unclear, but the report does provide rriany useful details for those considering a similar undertaking. lavahn overmyer school of library science case western reserve university subject access to a data base of library holdings alice s. clark: assistant dean for readers' services, university of new mexico general library, albuquerque. at the time this research was undertaken, the author was head of the undergraduate libraries at ohio state university. 267 as more academic and public libraries have some form of bibliographic description of their complete collection available in machine-readable form, public service librarians are devising ways to use the information for better retrieval. research at the ohio state university tested user 1'esponse to paper and com output from selected areas of the shelflist. results indicated usm·s at remote locations found such lists helpful, with some indication that paper printout was more popular than microfiche. while many of the computer applications in special libraries were designed to improve subject access to the collections, the systems adopted in academic and public libraries have often been those which would handle various file operations and improve control of circulation or technical processing functions. once some of the data describing the items in the collection became available in machine-readable form, reference librarians have been tempted to find ways to use it for subject retrieval. in november 1970, the ohio state university ( osu) libraries began to use its automated circulation system using a data base representing its complete shelflist with limited information on each title: field no. field 1 call number 2 author 3 title 4 lc number-or nolc if none available 5 title number 6 publication date (if available) 7 ser-serial indicator. when present indicates the title is a serial. 8 neng-non-english indicator. when present indicates the title is

circulation status date charged in the form of year, month, day date due in the form of year, month, day the system, modified from time to time, provided access by call number, record number, or author-title with an algorithm consisting of the first four letters of the author's name plus the first five letters of the title. a title search was also possible by entering four letters of the first significant word and five letters of the second significant word or five dashes. as soon as the system was implemented, it was immediately evident that the search option was one of the most important features of the system. the circulation clerk at any location either in the main library or in any department library could search the author and title and find: ( 1) if the osu libraries had the book; ( 2) where it was regularly housed; and ( 3) its status (charged out, missing, lost, or available for circulation). all of this was possible without checking the card catalog except when problems of identifying the main entry existed. the immediate lack was, of course, the subject approach. as use of the system continued and library personnel became more sophisticated, various procedures offering some kind of subject approach were developed. the title search option is one possibility for finding subject access. for example, to find a book on "evolution" one can enter the title search command tls/evol----and receive a report that there are 757 titles in which evolution is the first significant word. the terminal will then print out items as follows: tls/evol----page 1 757 matches 01 lan, h. j. 02 moody, paul amos. 1903 03 brosseau, george e 04 adler, irving 05 lotsy, j. p. 0 skipped evolutie (not all retrieved) introduction to evolution evolution evolution

option to display others including all 757 titles if necessary. it is also possible to manipulate this option further since this first. search may tum up the name of an author recognized as an authority on the subject. in this case, when thomas huxley's evolution and ethics appears, the terminal attendant changes to an author-title search, ats/huxlevolu, and finds eight matches, four books by thomas huxley and four by julian sorell huxley on the same subject: ats/huxlevolu page 1 8 matches 01 huxley, thomas henry 02 huxley, thomas henry 03 huxley, julian 04 huxley, thomas henry 05

subject approach is, of course, by call number. the system contains an option that permits a search on the general call number. the operator may enter either a real or an imaginary call number and receive the fifteen titles preceding and the fifteen titles subsequent to it in the shelflist. for example, with the command sps/hm106h9, using the call number from the previous example, the following ten titles will appear with that call number as the central item: sps/hm106h9 11 hm106g77 graubard, man the slave and master 12 hm106h3 haycraft, darwinism and race progress 13 hm106h57 herter, c.

of the university, an experiment was tried using a computer printout of certain selected parts of the shelflist. since microfiche is less expensive and more compact to handle, there were good reasons for using this form rather than the paper printout form. this was an obvious application for computer output microfiche (com). once subject access/clark 271 a master frame has been produced by com, the cost of additional copies is negligible. in order to test acceptance of form more accurately, it was decided to provide a list in each form to test on sample populations. to cover some of the subjects taught at the agricultural and technical institute at wooster, a total of 20,672 titles were selected in the following areas: agricultural economics botany agriculture agricultural machinery wood technology woodworking hd1401-2210 qk10-942 s tj148g-1496 ts80g-937 tt13g-200 2,121 titles 1,039 titles 17,157 titles 6 titles 197 titles 152 titles these titles were printed in a hard-copy printout in the following format with a program designed by gerry guthrie of the research and development division of the osu libraries: call number = tj1496c3a3 title number = 196795 author = caterpillar tractor company title = fifty years on tracks publ. date = 1954 holdings = cool com regular lc number = 55-20529 the physical form of the resulting documents varied somewhat due to the fact that each subject area was put in one cover. this meant "agriculture" ( s) with 17,157 titles was too bulky to carry around, but "wood technology" was compact and easily carried to one's office or home for leisurely browsing. a brief questionnaire was used to test the reaction to the list. responses were received from 6 percent of the students and faculty at the agricultural and technical institute. with the usual assumption that some students are not library users, there was some validity to the sample. results tabulated from these questionnaires fell into three categories: ( 1) nature of use; ( 2) value of the list; and ( 3) response to its form and format. since some questions were left blank, the totals were often less than 100 percent. nature of use the responses turned out to be evenly divided between faculty and students, 46 percent for each with some leaving this question blank. the faculty indicated that two-thirds of the use was for themselves and one-third for the students. students, of course, used it totally for their own purposes. the actual purpose of the list had been envisioned as access to the main campus collection, and increases in interlibrary loans indicated that it was 272 journal of libmry automation vol. 7/4 december 1974 effective. loans during the month of october 1973 totaled four while november's loans totaled thirty-four, showing a marked difference after the delivery of this search tool on october 31. the questionnaire showed that 77 percent indicated they used the information for this purpose. it should not have been a surprise to librarians to find that 34 percent of the sample population used the information to order a duplicate copy for the wooster ati library, an indication of readers' known proclivity for wanting their material close at hand. users' evaluation the increase in interlibrary loans was probably a better reflection of the users' approval than the actual questionnaire results, although the results themselves were also highly positive. seventy-seven percent checked that they found it valuable, against 15 percent who did not. eighty-five percent said they wanted more lists. requests for additional suggestions included a request to keep it up to date and a request to limit it to just recently published items, while another person asked for all of the titles located in the agricultural engineering library. the requests indicated that several additional subject areas were wanted: communication skills, personnel management, human relations, use of airplanes in agricultural, irrigation, and drainage engineering, and environmental pollution. suitability of form and format some attempt was made to determine how people react to the admittedly inconvenient form of a computer printout. since financial considerations limited the possibilities to either this form or microfiche, those options were presented in the questionnaire. preference for the paper form was expressed by the users of the list in this form-84 percent to 8 percent who would have preferred microfiche. · the population was evenly divided as to whether or not they wished to have the list in this call number order-50 percent wanted it by straight shelflist or call number order and 50 percent wanted it alphabetically by author. the latter response may very well reflect the proportionally large number of respondents who were faculty and who supposedly would know the authors in their fields and do not use a subject approach when seeking materials. while the original purpose of the research was to provide better subject access to a remote collection, it was also important to find out more about the user's response to microfiche if he could be given an improvement in service or a service he did not previously have. microfiche would be both more compact and less expensive if lists of this type were to be provided in many subjects and continually updated. for the microfiche section of the research project the library of congress classifications covering classics and related fields were chosen, partly subject access/clark 273 on the basis that faculty in these areas had agreed to participate and encourage their students to use the list. included were: de1-de98 df101-df289 dg11-dg209 n563q-n5790 na20q-na335 pa-all z7001-z7005 history-the mediterranean world history-greece history-italy history of art-greek and roman architecture-history-greek and roman language and literature of greece and rome bibliographies in linguistics, roman and greek literature, teaching languages this subset produced about eleven thousand titles. the format of the com was the same as that on the paper printout, with general titles appearing at the top of each sheet or frame, e.g., shelflist-classics-greece. this took twenty-two microfiche with sixty-nine frames each listing seven or eight titles. the last frame on each fiche was an index to that fiche. a nonreduced (eyeball) character at the top listed the first call number on the fiche. it was envisioned that the user might know the general classification number, search for it by the eyeball character, then consult the index in the last frame to locate the proper frame for a specific class. in this way the user could browse through the subject area. the chief advantage of com lay in the fact that the small envelope of microfiche and a portable reader were easy to check out of the library and carry home or to an office where the user could browse through the library shelflist at a leisurely pace. since initial reaction was negative, a subject index was prepared to make the list more usable to undergraduate students. this index was made up of the appropriate entries which appeared in the library of congress classification schedules, with all entries consolidated into one alphabet. 1 using this index to find an entry-for example, "caesar, c. julius" -the student would find two areas to search: dg261-267 and pa6235-6269. he would find these areas on the microfiche with the eyeball characters, then search the index frame to find the appropriate pages. the classics list with its index and instructions was packaged in neat, loose-leaf notebook form and, together with a portable reader, presented to classics faculty at two regional campuses. a set was also available in the library. the results were completely negative. reliance upon the cooperation of too small a number of cooperating teachers may have invalidated this part of the research, but the contrast in response to the similar printed list raised serious questions about user response to microfiche in an index or reference book situation.2 it had been anticipated that a population in the humanities or social sciences would have had more need than the science group for what was essentially a book list since serial titles did not include 27 4 j oumal of library automation vol. 7 i 4 december 197 4 holdings. the complete lack of interest from the faculty in the field of classics was an unexpected disappointment but no firm conclusions could be drawn without a research strategy designed to remove any possible variables. conclusion increased use of marc cataloging through such systems as oclc and ballots will mean many more libraries will have their total holdings in machine-readable form with the capability of using their records in new ways. programs for distributing microfiche copies of library catalogs such as georgia tech's lends program provide inspiration for public service librarians to make use of the data and technology that technical services automation projects are supplying. 8 this experiment in manipulating machine-readable library records for use in subject searching was an attempt toward better retrieval of a library's collection and indicated that such programs would be useful to extend service outside a single library location. references 1. it may soon be possible to do this in a

chemists, by elizabeth e. duncan. metuchen, n.j.: scarecrow press, 1972. 150p. $5.00. this book starts with a five-page foreword by allen kent entitled "kwic indexes have come a long way-or have they?" kent is always interesting but when one detects that his foreword is becoming almost an. apologia, one wonders just what is to come. the remainder of the book (apart from the index) appears already to have been presented as dr. duncan's ph.d. thesis at the university of pittsburgh. the first two chapters are the usual sort of stuff, taking us from alexandria in the third century to columbus, ohio in 1970, with undistinguished reviews of user studies and the history of the chemical abstracts service. the remaining sixty-four pages of text report and discuss a study of the use of ca condensates by quite a small sample of academic and industrial chemists in the pittsburgh area. the objective appears to have been to compare profile hits with periodical holdings and interlibrary loan requests at the client's library so that a decision model for the acquisition of periodicals could be developed. on the author's own admission, this objective was not achieved. a certain amount of data is presented but it is difficult to draw many conclusions from it, other than the fact that chemists do not appear to follow up the majority of profile hits that they receive nor do they use the current issues of chemical abstracts very frequently. it is difficult to understand why this material was published in book form. it could have been condensed to one or possibly two papers for ].chem.doc. or perhaps even left for the really diligent seeker to find on the shelves of university microfilms-but, as the old testament scribe bemoaned, "of making many books there is no end." at the bottom of page 118 a reference is made to the paper by abbott et al. in aslib proceedings (feb. 1968); at the top of page 119 the same paper's date is given as january 1968. other errors are less obvious, but one really questions whether the provision of a short foreword and an index makes even a good thesis worth publishing in hard covers. r. t. bottle the city university london, u.k. computer-based reference service, by m. lorrai'ne mathies and peter g. watson. chicago: american library assn., 1973. 200p. $9.95. the archetypal title and model for all works of explication is ....... without tears. lorraine mathies and peter watson have attempted the praiseworthy task of explaining computer-produced indexes to the ordinary reference librarian, but for a number of reasons, some of them probably beyond the control of the authors, the tears will remai'n, perhaps one difficulty is that this book was, in its beginnings at least, the product of a committee. back in 1968 the information retrieval committee of the reference services division of the ala wanted to present to "working reference librarians the essentials of the reference potential of computers and the machine-readable data they produce" (p.xxix). the proposal worked its way (not untouched, of course) through several other groups and eventually resulted in a preconference workshop on computer-based reference service being given at the dallas convention of 1971. the present book is based on the tutor's manual which mathies and watson prepared for that workshop but incorporates revisions suggested by the ala publishing services as well as changes initiated by the authors themselves. with so many people getting into the planning act, it is not surprising that the various parts of the book should end up by working at cross purposes to each other. unfortunately, the principal conflicts come at just those points where a volume of exposition needs to be most definite and precise: just what is the book trying to do and for whom? at the original workshop, the eric data base was chosen as a "model system" since educational terminology was more likely to be understood than that of the sciences. and because the participants were to learn by doing, they were told a great deal about eric so as to be able to "practice" on it. the trouble is that these objectives do not translate well from workshop to print. the detafls about eric, which may have been necessary as tutors' instructions, seem misplaced in book form. almost half the present book is devoted to a laborious explanation of how eric works and this is a great deal more than most workaday reference librarians will want to know about it. moreover, it is no longer clear whether mathies and watson aim to train "producers" or "consumers." the welter of detail suggests that they expect their readers to learn hereby to construct profiles and to program searches but it is highly doubtful that skills of this kind can or should be imparted on a "teach yourself" basis. once mathies and watson leave eric behind, they seem on surer ground. part ii (computer searching: principles and strategies) begins with a fairly routine chapter on binary numeration which is perhaps unnecessary since this material is easily available elsewhere. however, the section quickly moves on to an excellent explanation of boolean logic and weighting, describes their application in the formulation of search strategies, and ends with an admirably succinct and demystifying account of how one evaluates the output (principles of relevance and recall). the reader might well have been better served if the book had indeed begun with this part. the last section (part iii: other machine readable data bases) is also very useful, particularly for the "critical bibliography" (p.153) in which the authors describe and evaluate ten of the major bibliographic data bases. this critical bibliography is apparently a first of its kind, which makes the authors' perceptive and frank comments all the more welcome. part iii also contains chapters on marc and the 1970 census but, sh·angely enough, does not include a final resume and conclusions. it is true that in each book reviews 325 chapter there is a paragraph or so of summary but this is hardly a satisfactory substitute for the overall recapitulation one would expect. in the final analysis, indeed, one's view of the book will depend on just thatwhat one expects of it. if "working reference librarians" expect to read this book in order to be no longer "intimidated by these electronic tools" (p.ix), they are apt to be disappointed. the inordinate emphasis on eric, the rather dense language, and the fact that the main ideas are never pulled together at the end will all prevent easy enlightenment. however, if our workaday reference librarians are willing to work their way through a fairly difficult manual on computer-based indexing as in effect a substitute 'for a workshop on the subject, they will find this book a worthwhile investment of their time-and tears. samuel rothstein school of lihl'arianship university of british columbia the circulation system at the university of missouri-columbia library: an evolutionary approach. sue mccollum and charles r. sievert, issue eds. the larc reports, vol. 5, issue 2, 1972. 101p. in 1958 the university of missouri-columbia library was one of the first libraries to mechanize circulation by punching a portion of the charge slip with book and borrower and/ or loan information. in 1964 an ibm 357 data collection system utilizing a modified 026 keypunch was installed, but not until 1966 was 026 output processed on the library owned and operated ibm 1440 computer. however, budgetary constraints forced a transfer of operations in 1970 to the data processing center, which undertook rewriting of library programs in 1971. after explanation of hardware changes and an overview of the circulation department organization and data processing center operation, this report deals in depth with the major files of the circulation system-circulation master flle and location master file-and the main components of the circulation system-edit, update, overdues, fines, interlibrary loans, 326 journal of libmry automation vol. 7/4 december 1974 address file, location file, reserve book, listing of files, special requests, and utility programs. many examples of report layouts are included, particularly those accomplished by utilizing data gathered from main collection and reserve book loans. although this off-line batch processing circulation system is limited in that it does not handle any borrower reserve or lookup (tracer) routines, both of which are possible in off-line systems, the university of missouri-columbia system has merit as a pioneer system which influenced other university library circulation system designs in the 1960s. detailed reference given throughout the report to changes in the original library programs not only makes it of value as a case history for any library interested in circulation automation but also indicates the important fact that library programs do change and evolve in response to new demands and technological capabilities. lois m. kershnm university of pennsylvania libraries national science information systems, a guide to science information systems in bulgaria, czechoslovakia, hungary, poland, rumania, and yugoslavia, by david h. kraus, pranas zunde, and vladimir slamecka. (national science information series) cambridge, mass.: the m.i.t. press, 1972. 325p. $12.50. as indicated by the title, this volume provides a comparative description and analysis of the various organizational or political structures which have been adopted by six counb·ies of central and eastern europe in their attempts to develop effective national systems for the dissemination of scientific and technical information. for each country there is a detailed account of the national information system now existing, with a brief outline of its antecedents, a directory of information or documentation centers, a list of serials published by these centers, and a bibliography of recent papers dealing with the development of information systems in that country. this main section of the book is preceded by a brief review of the common characteristics of the six national systems and an outline of steps being taken to achieve international cooperation for the exchange of information in specific subjects. of particular interest is the description of the international center of scientific and technical information established in moscow in 1969, and which is now linked to five of these national systems. no attempt is made to describe the techniques being used to store, retrieve, and disseminate information. the authors point out that the six countries being examined "have experimented intensely with organizational variants of national science information systems." unfortunately, they do not attempt to indicate which of these organizational structures was most effective in bringing about the desired results. undoubtedly, this would have been an impossible task and probably not worth the effort, since a successful type of organization in a socialist country would not necessarily be effective in a democracy. the book will be of interest to political scientists and to those seeking the most effective ways of coordinating the information processing efforts of all types of government bodies. it will be only of academic interest to the information specialist concerned primarily with information processing techniques. jack e. brown national science library of canada ottawa information retrieval: on-line, by f. w. lancaster and e. g. fayen. los angeles: melville publishing co., 1973. 597p. lc: 73-9697. isbn: 0-471-51235-4. have you been reading the asis annual review of information science and technology year after year and wishing for a compendium of the best information and examples of the latest systems, user manuals, cost data, and other facts so that you would not have to go searching in a library for the interesting reports, journal articles, and books? well, if you have (and who hasn't), your prayers have been answered if you are interested in online bibliographic retrieval systems. the authors of the handy reference book have collected and reprinted, among other things, the complete dialog terminal users reference manual, the supars user manual, the user instructions for aim-twx, obar, and the caruso tutorial program. each of these systems, and several others (arranged alphabetically from aim-twx [medline] to to xi con [toxline]), is described and illustrated. features and functions of on-line systems, such as vocabulary control and indexing, cataloging, instruction of users, equipment, and file design, are all covered in a straightforward manner, simply enough for the uninformed and carefully enough so that a system operator could compare his system's features and functions with the data provided. richly illustrated with tables, charts, graphs, and figures, up-to-date bibliographies (only serious omission noticed was the afips conference proceedings edited by d. walker), and subject and author indexes, this volume will stand as another landmark in the state-of-the-art review series which the wiley-becker & hayes information science series has come to represent. emphasis has been placed on the design, evaluation, and use of on-line retrieval systems rather than the hardware or programming aspects. several of the chapters have a broader base of interest than on-line systems, covering as they do performance criteria of retrieval systems, evaluating effectiveness, human factors, and cost-performance-benefits factors. easy to use and as up to date and balanced a book as any in a rapidly changing field can be, lancaster and fayen have given students of information studies and planners and managers of information services a very valuable reference aid. pauline a. atherton school of information studies syracuse university national library of australia. australian marc specification. canberra: national library of australia, 1973. 83p. $2.50. isbn: 0-642-99014-x for those readers who are familiar with book reviews 327 the library of congress marc format, the australian marc specification will be, for the most part, self-explanatory. the intent of the document is to describe the basic format structure and to list the various content designators that are used in the format. no effort was made to include any background information or explanation of data elements. because of this, the reviewer found it necessary to refer to other documents, e.g., precis: a rotated subiect index system, by derek austin and peter butcher, in order to complete a comparative analysis of the australian format with other similar formats. perhaps the value of reviewing a descriptive document of this type lies in discovering how the format it describes compares to other existing formats developed for the same purpose. the international organization for standardization published a format for bibliographic information interchange on magnetic tape in 1973, international standard iso 2709, the australian format structure is the same throughout as the international standard. the only variance is in character positions 20 and 21 of the leader, which the australian format left undefined. a comparison of content designators cannot be made with the international standard because it specifies only the position and length of the identifiers in the structure of the format, but not the actual identifier (except for the three-digit tags 001-999 that identify the data fields). the best comparison of content designators can be made with the lc marc format, since the australian format uses many of the same tags, indicators, and subfield codes for the same purposes. the australian format has assigned to the same character positions the same fixed-length data elements as the lc format except for position 38, which is the periodical code in the australian format and the modified record code in the lc format. in the fixed-length character. positions for form of contents, publisher (government publication in lc marc), and literary text (fiction in lc 328 journal of library automation vol. 7/4 december 1974 marc) , the australian format assigned different codes than lc. in general, the australian format uses the same three-digit tags as lc to identify the primary access fields in their records, e.g., 100, 110, 111 for main entries; 400, 410, 411, 440, 490 for series notes; 600, 610, 611, 650, 651 for subject headings; and 700, 710, 711 for added entries. for the remaining bibliographic fields there are some variations in tagging between the two formats. the australian marc has chosen a different method of identifying uniform titles, and has identified five more note fields in the 5xx series of tags than has lc. the australians have also added some manufactured fields to their record. these fields do not contain actual data from the bibliographic record, but rather are fields consisting of data created by program for control and manipulation purposes, or from lists such as the precis subject index. the australian format has also included, as part of its record, a series of cross-reference fields identified by 9xx tags. lc has reserved the 9xx block of tags for local use. the use of indicators differs in most instances between the two formats. both allow for two indicator positions in each field as specified by the international standard format structure. however, the information conveyed by the indicators differs except where the first indicator conwhich means no intelligence carried in this position. in the australian format the indicators in the 6xx block of tags have three different patterns. inconsistency of this kind does not tend to destroy compatibility with other coding systems using the same format structure, as long as sufficient explanation and examples are given from which conversion tables may be developed by the institutions with whom one wants to exchange, or interchange, bibliographic data. an even greater degree of difference exists between the two formats in the subfield codes used to identify data elements. the australian marc has identified some data elements that lc has not, e.g., in personal name main entries, the australian record identifies first names with subfield code "h," whereas lc does not identify parts of a personal name, only the form of the name, i.e., forename form, single surname, family name, etc. in most of the fields the two formats have defined some of the same data elements, but each uses a different subfield code to represent the element. in the australian document, under each field heading, the subfield codes are listed alphabetically with a data element following each code. this arrangement causes the data elements to fall out of their normal order of occurrence in the field, i.e., name, numeration, titles, dates, relator, etc. for example: personal name main entry (tag 100) subfield code a b amtralian marc entry element ( name) relator lc marc entry element (name ) numeration c dates d e second or subsequent additions to name numeration titles ( honorary) dates relator f additions to name other than date date (of a work) veys form of name for personal and corporate name headings. within each block of tags, lc has made an effort to remain consistent in the use of indicators, e.g., in the 6xx block for subject headings, the first indicator specifies form of name where a form of name can be discerned. where no form of name is discernable such as in a topical subject heading (tag 650), a null indicator or blank is used the example demonstrates the need for precise definition and documentation of data elements for the purpose of conversion or translation when interchanging data with other institutions. the australian format has included the capability of identifying analytical entries by using an additional digit (called the level digit) placed between the tag and the indicators to identify the analytical entries. a subrecord directory (tag 002) is present in each record containing data for analytical entries. the australian document includes appendixes for the country of publication codes, language codes, and geographical area codes that were developed by the library of congress. their only deviabook reviews 329 tion from lc marc usage is in the country of publication codes, where the australians have added entities and codes for australian first-level administrative subdivisions. patricia e. parker marc development office library of congress mitchell multimedia will have a profound effect on libraries during the next decade. this rapidly developing technology permits the user to combine digital still images, video, animation, graphics, and audio. it can be delivered in a variety of finished formats, including streaming video on the web, video on dvd/vcd, embedded digital objects within a web page or presentation software such as powerpoint, utilized within graphic designs, or printed as hardcopy. this article examines the elements of multimedia creation, as well as requirements and recommendations for implementing a multimedia facility in the library. t he term multimedia, which some may remember being used in the early 1970s as the name for slide shows set to music, now is used to describe “a number of diverse technologies that allow visual and audio media to be combined in new ways for the purpose of communicating.”1 almost all personal computers sold today are capable of viewing multimedia; many can, with minor modifications, also create multimedia. one of the most important features of multimedia is its flexibility. multimedia creation has several distinct elements—inputs, processes performed on those inputs, and outputs (see figure 1). each element can be described as follows. � inputs—new video can be recorded, or existing video, stored on a hard disk, cd/dvd, or tape can be imported. the same is true of audio, with the added flexibility of creating soundtracks or sound effects later, during the editing process. digital still images can be used, either shot on a camera or created by scanning an existing picture. digital artwork or animated sequences created in other software also can be brought in. � processing—regardless of the source, these digital inputs are loaded into the editing software. at this stage, the user will select and arrange the images and sounds, and the software may permit special effects to be created. in addition, the editing software may compress the file so that it is easier to use than the large file sizes used in raw video and audio recording. � outputs—at this point, the user has more choices to make. the new multimedia file can be sent to a program that will encode it for a streaming video in any one of a variety of popular formats, such as windows media, realmedia, or clipstream. then it can be mounted on a web site (either a regular page or within courseware such as webct or blackboard), or the file could be burned onto a cd or dvd, or it could be used within presentation software such as microsoft powerpoint. or the output file from the editing process could be encoded and embedded so that it is an avatar running as part of a web page with a product such as rovion bluestream. the possibilities are nearly endless. all of this is made possible by advances in technology on a variety of fronts. one of the happy anomalies in technology is that greater performance is frequently accompanied by lower costs. this is certainly the case with much of the activity surrounding multimedia. the following factors have fostered advances in multimedia: � increase in processing power and decrease in cost of computer hardware; � quality and affordability of video equipment; � compression of multimedia files; � consumer broadband internet access; and � current multimedia editing software the first two technology factors concern the equipment involved in multimedia production. leading off is the familiar, ever-increasing speed of processors and improved memory and hard-drive space, all delivered for less money. this trend is something that many people take for granted, but a reality check is sometimes in order. the processor in the typical desktop machine on advertised special today is approximately forty-four times as fast as the first pentium processor sold ten years ago, and is equipped with sixteen times as much ram and 117 times as much hard-drive space—at 20 percent of the cost of the old machine (not even adjusted for inflation!). the second factor is the incredible quality available in consumer-market video equipment at reasonable costs. while the images produced with consumer-grade video would not play well at the local megaplex movie theater, they look very good on the small screens found on computers, televisions, and classroom projectors. the third factor is that tremendous compression of multimedia files can be achieved during the editing process. an incoming raw-video file (in the standard .avi format) can be compressed with editing, encoding, and dedicated third-party compression software to an incredible 1 to 2 percent of its original size, and it will still retain very good quality as a digital object on the web and in other desktop viewing applications. the fourth factor is extremely critical for the success of multimedia web applications. home access is shifting away from dial-up access to broadband, with its greatly increased transfer rates. half of all united states homes with internet access are already using broadband, and the 32 information technology and libraries | march 2005 gregory a. mitchell (mitchellg@utpa.edu) is assistant director, resource management at the university of texas—pan american library, edinburg, texas. distinctive expertise: multimedia, the library, and the term paper of the future gregory a. mitchell forecast is for steady increase in these numbers.2 although not all broadband is created equal, it is all significantly faster than dial-up access. the final technology factor concerns the software that is currently available to the multimedia web developer. a developer can achieve some quite professional results with even the most basic products, and then can grow into more complex software that supports increasing levels of expertise. once again, this software is being sold in the price range that typical consumers can afford. � small really is beautiful creating a multimedia lab in the library need not be a large, complex undertaking. in fact, it can be very low cost and as simple as a single workstation. so it is scalable, allowing the library to start small and build in complexity and cost as time, money, and human resources will permit. at the bare-bones minimum, a multimedia lab would consist of a workstation with the software necessary for acquiring, editing, and outputting the files. for practical purposes, though, the workstation should be equipped with a network connection, a cd/dvd burner, a scanner, and a webcam with microphone. another very useful option is an analog-digital bridge device, which enables the capture of analog input (such as vhs tape) into digital files for the editor. to achieve better-quality video when shooting original content, a digital-video camera, tripod, wireless microphone, and portable light kit would be recommended. since more time typically is spent at the editing station than with the camera, the lab can be expanded with additional workstations before investing in another camera. experience at the author’s institution has shown that it is possible to operate a lab with ten workstations and only three video cameras and three still cameras. finally, output from the editing process will likely be printed, so a photoquality printer is another convenient option. this illustrates that the entry into multimedia work need not be a large expense, especially if an existing workstation and any other equipment is already available. if a fairly recent workstation is available to dedicate to the project, the library’s total startup cost could range from $200 to $1,000. not many new library services can be launched for as little as that. rather than dwell on equipment specifications, as that is not the intent of this discussion, the reader may consult the excellent tutorials available from desktop video and pc magazine’s online product guide.3 finally, the creation of a studio is a worthwhile option. although some video will need to be shot on location, many times it is possible to set up and shoot in just one place. a studio is the best place in which to work because it is a controlled environment. it does not need to be large or complicated, and a quiet office or study room can be set up with little effort and expense. the studio gives the users control over the sound and the lighting, and involves minimal setup time for projects. � the research paper of the future multimedia has begun to attract attention in the library community. joe janes, chair of library and information science at the information school at the university of washington and the person responsible for developing the internet public library, recently stated he foresees a growing role for multimedia in the library. it will replace much of the traditional, text-based communication that people are accustomed to. for example, multimedia projects can become the research paper of the future for students.4 it is the media in which many library customers will be working. experience from the author’s institution with creating a multimedia lab would seem to confirm his observation. during the first year and a half of operation, use of the lab has steadily increased (see figure 2). � collaboration the multimedia lab opens the doors to collaborative opportunities with faculty and students from a variety of disciplines across campus. this is because multimedia, like geographic information systems (gis) or other electronic information and communication technologies, is a tool and is not discipline-specific. as important as it is to make the connection with faculty, this media is something with which the students will frequently lead the figure 1. multimedia creation process distinctive expertise: multimedia, the library, and the term paper of the future | mitchell 33 34 information technology and libraries | march 2005 way. they are, after all, the mtv generation, and multimedia has an incredible appeal to their visual orientation. faculty themselves have used it to augment their web-based courses as well as traditional classroom instruction. the author ’s library has even initiated a multimedia résumé service for graduating students. the students can record a video introduction of themselves, encode this as a rovion bluestream avatar, and post it with their résumés on the web. this creates a much stronger impression than a standard résumé, hopefully giving the students an edge in promoting themselves on the job market. even more impressive is the variety of projects that are created in the lab by the students. one might expect to see interest from students in art and communications classes, but students come from many other disciplines as well. for example, business students have effectively used multimedia in their graduate-school business-plan presentations, while biology students like to use the graphics capabilities to study close-ups of slides. education students have employed it to produce multimedia instructional aids, and a sociology student put together a presentation on underserved, low-income neighborhoods. the library supplies the facility and instruction—only the imagination of students is needed. libraries have always been involved in the students’ research and writing process, by providing content, instruction, and facilities for producing the final research product. the same is true in the multimedia environment, although implementing a multimedia lab calls for some new skills for librarians. these include familiarity with basic principles of videography, learning how to use the cameras and other equipment, and gaining some mastery of the editing and encoding software. � why put it in the library? in addition to the research-paper analogy, the author believes that librarians can point with pride to the values and value that libraries offer their communities. it is a central and neutral location—not in one department’s or college’s turf. libraries are conveniently open for many hours per week. many of the information resources that students might use to prepare the presentation are in the library. and librarians have a professional ethic that drives them to provide instruction and assistance for the services the library offers. since multimedia production does have a learning curve and most new users need help in mastering the technology, it does not fit very well with the typical 24/7 drop-in computer lab that the campus information technology (it) often operates. this is a good opportunity for librarians to recognize some of their strengths and capitalize on them. in addition, this can be a breath of fresh air for librarians. here is an opportunity to learn about something new and creative. most people find that they have less room for creativity as time goes by.5 with a multimedia lab in the building, it will offer the librarians the opportunity to create multimedia productions for the library, besides assisting students and faculty with their projects. � potential problems there are some obstacles to overcome, of course. they need not be seen as major, but it is best to be realistic when beginning any new venture. it is almost always a good idea to start small, with a pilot project that will yield valuable lessons before venturing into anything big. � equipment—define what specifications are needed, see what is already available to use or borrow, then figure out what you will actually need to buy. � software—check out the variety of software for editing and production; think about how you want to begin using multimedia (primarily on the web, in presentation software such as powerpoint, as standalone videos on cds and dvds). � money—if funding permits, a library can invest several thousand dollars in a high-end multimedia computer, associated peripherals such as a color printer and one or more scanners, and a software suite to meet initial anticipated demands for multimedia creation and editing. if funding is scarce, you may want to investigate what existing equipment could be used in support of a pilot project. � location—this needs some space of its own, accessible to students and monitored by staff. although the figure 2. university of texas—pan american library multimedia lab usage editing workstation could be in an area with other computers, a quiet area is needed for shooting video so that there will not be interference from noise and unwanted foot traffic through the shots. � staffing and training—a multimedia lab is not a good candidate for self-service. librarians and staff who will provide the service need to learn how to use the equipment and software. make sure that they all have an acceptable level of competence and confidence so that the library can shine with its new service, but expect that everyone will need to continue to learn and grow in their proficiency. if your library plans to produce its own multimedia sessions as well, it would be a good investment to attend a class on television or video production. � hours—how many hours per week will the new service be available? if it is the entire time the library is open, be prepared to train plenty of staff. repeat users will need less help as their skills increase (by the way, some of these students can be great workstudy employees). � instruction—plan to offer formal orientation and instruction sessions to faculty and their classes. if your lab is small, this is challenging, but it can be accomplished with some creativity. for example, a general instruction session on concepts can be done in a classroom, followed up by a series of small groups working by appointment for the appliedlearning component in the multimedia lab. the author and a colleague have even done instruction outside the library using laptops and cameras, creating a de facto mobile studio. � copyright—if there are already vcrs or photocopiers in the library, you have had to deal with this issue. the pan american library at university of texas does not allow people to use its lab to copy movies, which is a request that surely will come to you, and we post the usual copyright notices just as we do at our photocopiers. for some excellent information on copyright, visit the american library association web site (www.ala.org). � evaluation—plan on at least basic evaluation of the service. this can include an assessment of the effectiveness of the instruction sessions, a survey of satisfaction with the lab itself, a questionnaire on the intended uses of the multimedia projects, demographic data on the students, or other student input. logs of the number of uses and peak-demand periods are extremely useful for planning and for justifying further expenditures and staffing requests. � flexibility for the future—whatever you do in a pilot phase, always keep in mind that you want to keep an open mind—you are trying to learn from the experience so that you can make good decisions for the direction of this new service. it may not go exactly the way you originally thought, because of serendipity, or changes in technology, or very strong demand from some segments of the campus instead of others, or other environmental factors. � conclusion benefits to the library from the multimedia lab are many. one of the most important benefits is that it keeps the library involved in the process of academic communication, as the medium of the communication changes with technology. by being involved in this evolving medium at its early stages, the library is poised to pounce on opportunities to employ it to the benefit of the library in instruction and content delivery. the library also would position itself on campus as a key player in it and the leading local expert in the growing field of multimedia. since multimedia is a tool that crosses the entire range of subject disciplines on campus, it opens the doors of faculty to collaborate with librarians in exciting new ways. just as many campuses already have learning and collaborative communities that grew around their web courseware or gis endeavors, so too can one develop around multimedia. the appendix offers a list of multimedia web sites to consider. libraries are more than warehouses of books and periodicals. as more and more of our resources have been made available electronically, and indeed more of higher education has moved to electronic delivery, many libraries have been faced with declining gate counts, circulations, and reference statistics. as someone observed, we are victims of our own success. so what is the role of the library? we are intrinsically involved in the process of instruction, academic research, and communication. as kling observed, “one important strategic idea is that libraries configure their it services and activities to emphasize the distinctive expertise of their librarians rather than simply concentrate on the size and character of the documentary collection.”7 it is imperative therefore that libraries pick out the new trends that will allow them to excel by capitalizing on their traditional strengths. references 1. scala, inc. multimedia

geolibrary? a case of the idaho geospatial data center maria anna jankowska and piotr jankowski the article presents the idaho geospatial data center (igdc), a digital library of public-domain geographic data for the state of idaho. the design and implementation of igdc are introduced as part of the larger context of a geolibrary model. the article presents methodology and tools used to build igdc with the focus on a geolibrary map browser. the use of igdc is evaluated from the perspective of access and demand for geographic data. finally, the article offers recommendations for future development of geospatial data centers. i n the era of integrated transnational economies, demand for fast and easy access to information has become one of the great challenges faced by the traditional repositories of information-libraries. globalization and the growth of market-based economies have brought about, faster than ever before, acquisition and dissemination of data, and the increasing demand for open access to information, unrestricted by time and location. these demands are mobilizing libraries to adopt digital information technologies and create new methods of cataloging, storing, and disseminating information in digital formats. libraries encounter new challenges constantly. participation in the global information infrastructure requires them to support public demand for new information services, to help the society in the process of selfeducation, and to promote the internet as a tool for sharing information. these tasks are becoming easier to accomplish thanks to the growing number of digital libraries. since 1994, when the digital library initiative originated as part of the national information infrastructure program, the internet has accommodated many digital libraries with spatial data content. for example, the electronic environmental library project at the university of california, berkeley (http:/ /elib.cs. berkeley.edu/) provides botanical and geographic data; the university of michigan digital library teaching and learning project (www.si.umich.edu/umdl/) focuses on earth and space sciences; the carnegie mellon's informedia digital video library (www.informedia. cs.cmu.edu) distributes digital video, audio, and images maria anna jankowska (majanko@uidaho.edu) is associate network resources librarian, university of idaho library, and piotr jankowski (piotrj@uidaho.edu) is associate professor, department of geography, university of idaho, moscow, idaho. 4 information technology and libraries i march 2000 with text; and the alexandria digital library at santa barbara (http:/ /alexandria.sdc.ucsb.edu/) provides geographically referenced information. the alexandria digital library is of special interest in this article because it implements a model of a geolibrary. a geolibrary stores georeferenced information searchable by geographic location in addition to traditional searching methods such as by author, title, and subject. the purpose of this article is to present the idaho geospatial data center (igdc) in the larger context of a geolibrary model. igdc is a digital library of publicdomain geographic and statistical data for the state of idaho. the article discusses methodology and tools used to build igdc and contrast its capabilities with a geolibrary model. the usage of igdc is evaluated from the perspective of access and demand for geographic data. finally, the article offers recommendations for future development of geospatial data centers. i geographic information systems for public services terms such as digital, electronic, virtual, or image libraries have existed long enough to inspire diverse interpretations. the broad definition by covi and king concentrates on the main objective of digital libraries, which is the collection of electronic resources and services for the delivery of materials in different formats.1 the common motivation for initiatives leading to the development of digital libraries is to allow conventional libraries to move beyond their traditional roles of gathering, selecting, organizing, accessing, and preserving information. digital libraries provide new tools allowing their users not only to access the existing data but also to create new information. the creation of new information using the existing data sources is essential to the very idea of the digital library. since the information in a digital library exists in virtual form, it can be manipulated instantaneously by computer-based information processing tools. this is not possible using traditional information media (e.g., paper, microfilm) where the information must first be transferred from non-digital into digital format. since late 1994, when the u.s. national science foundation founded the alexandria digital library project, the number of internet sites devoted to spatially referenced information has grown dramatically. today, it would require a serious expenditure of time and effort to visit all geographic data sites created by state agencies, universities, and commercial organizations. in 1997 karl musser wrote, "there are now more than 140 sites featuring interactive maps, most of which have been created in the last two years." 2 this incredible boom in publishing reproduced with permission of the copyright owner. further reproduction prohibited without permission. spatial data is possible thanks to geographic information system (gis) technology and data development efforts brought about by the rapidly increasing use of gis. this new technology provides its users with capabilities to automate, search, query, manage, and analyze geographic data using the methods of spatial analysis supported by data visualization. traditionally, geographic data were presented on maps considered as public assets. according to a norwegian survey, the aggregate benefit accrued from using maps was three times the total cost of their production, even though maps provided only static information.3 today, the conventional distribution of geographic data on printed maps has become less efficient than distributing them in the digital format through wide area data networks. this happened largely due to gis's ability to separate data storage from data presentation. as a result, data can be presented in a dynamic way, according to users' needs. often gis is termed "data mixing system" because it can process data from different sources and formats such as vector-format maps with full topological and attribute information, digital images of scanned maps and photos, satellite data, video data, text data, tabular data, and databases. 4 all of these data types provide a rich informational infrastructure about locations and properties of entities and phenomena distributed in terrestrial and subterrestrial space. the definition of gis changes according to the discipline using it. gis can be used as a map-making machine, a 3-d visualization tool, and as an analytical, planning, collaboration, and business information management tool. today, it is hard to find a planning agency, city engineering department, or utility company (not to mention individual internet users) that has not used digital maps. this is why the number of users seeking spatial data in digital format has increased so dramatically. data discovery can be for gis users the most time-consuming part of using the technology. 5 as a result, libraries are faced with the growing demand for services that help discover, retrieve, and manipulate spatial data. the web greatly improved the availability and accessibility of spatial data but, at the same time, stimulated public interest in using geographic information. the continuing migration to popular operating systems (i.e., microsoft windows family) and the adoption of their common functionality has brought gis software to many desktops. tools such as arcview gis from environmental systems research institute, inc. (esri, www.esri.com) or maplnfo from maplnfo corporation (maplnfo, www.mapinfo.com) have become popular gis desktop systems. new software tools such as arcexplorer, released by esri, are focused on making gis more accessible, simpler, and available for use by the public. by taking advantage of the popularity of the web, attempts are being made to gain a wider acceptance of gis. in the wake of the simplification of gis tools and improved access to spatial data, a new exciting area of gis use has recently emerged-public participation gis.6 public participation gis by definition is a pluralistic, inclusive, and nondiscriminatory tool that focuses on the possibility of reducing the marginalization of societies by means of introducing geographic information operable on a local level.7 it promotes an understanding of spatial problems by those who are most likely to be affected by the implementation of problem solutions, and encourages transfer of control and knowledge to these parties. this approach leads to a broader use of gis tools and spatial data and creates new challenges for libraries storing and serving geographic data in digital formats. broadening the use of data and gis tools requires attention to data access. traditional libraries have often fulfilled the crucial role of being an impartial information provider for all parties involved in public decision-making processes. will they be capable of serving the society in this capacity in the digital age? i geolibrary as a repository of georeferenced information according to brandon plewe, the user of spatial data can choose among seven types of distributed geographic information services available on the intemet. 8 they range from raw data download, through static map display, metadata search, dynamic map browsing, data processing, web-based gis query and analysis, to net-savvy gis software. yet, another important new category of geographic data service that can be added to this list is geolibrary. goodchild defines a geolibrary as a library filled with georeferenced information where the primary basis of representation and retrieval are spatial footprints that determine the location by geographic coordinates. "the footprints can be precise, when they refer to areas with precise boundaries, or they can be fuzzy when the limits of the area are unclear." 9 according to buttenfield, "the value of a geolibrary is that catalogs and other indexing tools can be used to attach explicit locational information to implicit or fuzzy requests, and once accomplished, can provide links to specific books, maps, photographs, and other materials." 10 a geolibrary is distinguished from a traditional library in being fully electronic, with digital tools to access digital catalogs and indexes. it is anticipated that most of the information is archived in digital form. the value of a geolibrary is that it can be more than a traditional, physical library in electronic form.11 is this a geolibrary? i jankowska and jankowski 5 reproduced with permission of the copyright owner. further reproduction prohibited without permission. since its introduction, the concept of a geolibrary has been synonymous with the alexandria digital library (aol) project. once aol was defined as the internetbased archive providing comprehensive browsing and retrieval services for maps, images, and spatial information.12 a more recent definition characterizes aol as a geolibrary where a primary attribute of collection objects is their location on earth, represented by geographic footprints. a footprint is the latitude and longitude values that represent a point, a bounding box, a linear feature, or a complete polygonal boundary.13 according to goodchild (1998) a geolibrary' s components include: • the browser-a specialized software application running on the user's computer and providing access to geolibrary via a computer network. • the basemap-a geographic frame of reference for the browser's searches. a basemap provides the image of an area corresponding to the geographical extent of geolibrary collection. for the worldwide collection this would be the image of the earth. for the statewide collection this could be the image of a state. the basemap may be potentially large, in which case it is more advantageous to include it in the browser then to download it from a geolibrary server each time a geolibrary is accessed. • the gazetteer-the index that links place names to a map. the gazetteer allows geographic searches by place name instead of by area. • server catalogs-collection catalogs maintained on distributed computer servers. the servers can be accessed over a network with the browser, utilizing basic server-client architecture. the value of a geolibrary lies in providing open access to a multitude of information with geographic footprints regardless of the storage media. because all information in a digital library is stored using the same digital medium, traditional problems of physical storage, accessibility, portability, and concurrent use (e.g., many patrons wanting to view the one and only copy of a map) do not exist. i idaho geospatial data center in 1996, inspired by the aol project, a team of geographers, geologists, and librarians started to work on a digital library of public-domain geographic data for the state of idaho. the main goal of the project was the development of a geographic digital data repository accessible through a flexible browsing tool. the project 6 information technology and libraries i march 2000 was funded by a grant from the idaho board of education's technology incentive program. the project resulted in the creation of the idaho geospatial data center (igdc, http://geolibrary.uidaho.edu). the first in the state of idaho, this digital library is comprised of a database containing geospatial datasets, and geolibrary software that facilitates access, browsing, and retrieval of data in popular gis data formats including digital line graph (dlg), digital raster graphics (drg), usgs digital elevation model (dem), and u.s. bureau of census tiger boundary files for the state of idaho. the site also provides an interactive visual analysis of selected demographic/economic data for idaho counties. additionally, the site provides interactive links to other idaho and national spatial data repositories. the key component of the library is the geolibrary software. the name "geolibrary" is not synonymous with the model of geolibrary defined by goodchild (1998). it was rather adopted as a reference to a geolibrary browser-one of the components of the geolibrary. the geolibrary browser (gl) supports online retrieval of spatial information related to the state of idaho. it was implemented using microsoft visual basic 5.0/6.0 and esri mapobjects technology. the software allows users to query an area of interest using a search based on map selection, as well as selection by area name (based on uses 7.5-minute quad naming convention). queries return gis data including dems, dlgs, drgs, and tiger files. queries are intended both for professionals seeking gis-format data and nonprofessionals seeking topographic reference maps in the drg format. the interface of gl consists of three panels resembling the microsoft outlook user interface. our intent in designing the interface was to have panels that would be used in the following order. first, the map panel is used to explore the geographic coverage of the geolibrary and to select the area of interest. next, the query panel is used to execute a query, and finally the result panel allows the user to analyze results and to download spatial data. users can use a shortcut to go directly to the query panel and type their query. both approaches result in the output being displayed as the list of files available for download from participating servers. the map panel (figure 1) includes a navigable map of idaho, a vertical command toolbar, and a map finder tool. the command toolbar allows the user to zoom in, zoom out, pan the map, identify by name the entities visible on the map canvas, and select a geographic area of interest. geographic entity name identification was implemented as a dynamic feature whereby the name of entity changes as the user moves the mouse over the map. spatial selection provides a tool to select a rectangular area of interest directly on the map canvas. the map finder provides additional means to simplify the exploration of the map. reproduced with permission of the copyright owner. further reproduction prohibited without permission. the results panel shows the outcome of the query and includes important information about the data files: their size, type , projection, scale , the name of the server providing the data, as well as the access path (figure 4). based on this information , the user has the option of manually connecting to the server, using ftp protocol, and retrieving th e selected files. a much more convenient approach, however, is to rely on gl software to automatically retrieve the files through the software int erface. as an option , the result of the query can also be exported to a plain html document that contains links to all listed files . this feature can be very useful in the case of multifile files selected by the user and slow or limited-time internet access. this way the user can open the saved list of files in a web browser and download individual files as needed, without having to download all the files at once and tie up the internet connection for a long period of time. figure 1. map panel. the vertical toolbar provides zooming, panning , as well as labeling and simple feature querying capabilities. the map finder allows finding and selecting an area by county or usgs quad name . the screen copy here presents the selection of latah county in idaho. the result panel provides a flexible way to review and organize the outcomes of queries before commencing the download. one can sort files by name, size, scale, the user can select a county or a quad name and zoom in on the selected geographic unit. the query panel (figure 2) allows the user to perform a query, based either on the selection made on the map or a new selection using one of the available query tools (figure 3). in the latter case, the user can enter geographic coordinates (in decimal degrees) defining the area of interest. this approach is equivalent to selecting a rectangular area directly on the map, and will return all data files that spatially intersect with the selected area. optionally, the user can handpick quads of interest from the list. finally, a name can be entered to execute a more flexible query . for instance, the search containing the word "moscow" returns spatial data related to three quads containing "moscow" within their names. the query is executed when the user presses the query button . after the results are received, the application automatically switches to the results panel. projection, and server name . this feature may be useful if the user decides to retrieve data of only one type (e.g., dems), of one scale, or when the user prefers to connect only to a specific sever. in addition, individual records as well as entire file types can be selected to prevent files from being downloaded. the user can also remove selected files to scale down the set of data in the list. one of the most important assets of the gl browser is that all of the user activities described up to this point, with the exception of file download, take place entirely on the client-side without any network traffic. in fact, area/file selection as well as queries do not require an active internet connection. map exploration is based on vector-format maps contained in gl software and queries are run against the local database. such an approach limits bandwidth consumption and unnecessary network traffic. internet connection is only necessary to perform retrieval of selected files. is this a geolibrary? i jankowska and jankowski 7 reproduced with permission of the copyright owner. further reproduction

optionally, the user can enter geographic coordinates of the area or a text to search. 8 information technology and libraries i march 2000 the vulnerability of the client-side approach to data query is to be left with a potentially outdated local database. in order to prevent this problem from happening, the gl is equipped with a database synchronization mechanism that allows users to keep up with the server database updates. the client-side database, contained in gl software, which mirrors the schema of the server database, can be synchronized automatically or by the user's request. in either case, the gl client contacts the server-based database synchronizer on the server side and handles all necessary processes. since the synchronization is limited to database record updates, the network traffic is kept low, making gl suitable for limited internet connections. igdc is an open solution. new local datasets can be added or removed making the collection easily adaptable to different geographical areas. in addition, datasets can physically reside on multiple servers, taking full advantage of the internet's distributed nature. i evaluation of igdc use geospatial information is among the most common public information needs; almost 80 percent of all information is geographic in nature. published research reflecting those needs and the role of libraries in resolving them is not extensive. the efforts of federal, state, and local agencies collecting digital geospatial data and the growth of gis created an interest in the role of libraries as repositories of geospatial data. 14 the main obstacle to providing access to digital spatial information is its complexity. this is why the user-friendly interface is critical for presenting spatially referenced information.15 the igdc has been a first attempt at creating a user-friendly interface in the form of a map-based data browser allowing the users to access and retrieve geographic datasets about

----'-----'--"-'--'--'----'=---:__.:_::.._-_·-since the opening of igdc for public us e (april 1998), the geolibrary map browser was downloaded 1,352 times. the software proved to be relati vely easy to use by the public. out of fort y-four bug report s/ user questions submitted to igdc, most were concerned with filling out the software registration form and not with software failure. the igdc project spurred an interest in geographic information among students , faculty, and librarians at the university of idaho. in a direct response to this interest, the university of idaho library installed a new dedicated computer at the reference desk with geolibrar y software to access, view , and retrieve igdc data . i conclusion idaho geospatial data center is the first geospatial digital library for the state of idaho. it does not fulfill all requirements of a figure 4. the results panel. results of a query can be sorted; individual items can be removed from the list or can be deselected to prevent them from being downloaded . geolibrary model proposed by goodchild and others. the igdc has only two components of the geolibrary model; they are the datasets dissemination. during a one-year timeframe the number of successful hits was more than twenty-five thousand . almost 40 percent of users came from .com domain, 35 percent were .net domain users, 15 percent w ere .org, and 10 percent were .edu users (figure 5). tracking the geographic origin of users by state, the biggest number of users came from virginia, followed by washington, california, ohio, and idaho . the high number of users from virginia can be explained by the linking of the igdc site to one of the most popular geospatial data sites in the country-the united states geological survey (usgs) site. eighty-four percent of user sessions were from the united states; the rest originated from sweden, canada , and germany. the average number of hits per day on weekdays was around one hundred customers. the most popular retrievable information were digital raster graphics (drg) data that present scanned images of usgs standard series topographic maps at 1:24,000 scale. digital elevation models (dem) and digital line graphs (dlg) were less popular. the tiger boundary files for the state of idaho were in small demand . the popularity of drg-format maps and the fact that most of the users accessed igdc via the usgs web site makes plausible a speculation that most of the users were non-gis specialists interested in general reference geographic information about idaho including topography and basic land use information. geolibrary map browser and the basemap . the main difference between the geolibrary map browser and a web-based browser solution adopted by other spatial repositories is a client-side solution to geospatial data query and selection. spatial data query is done locally on the user's machine, using the library data base schema contained in the geolibrary map browser. this saves time by eliminating client-server communication delays during data searches, gives the user an experience of almost instantaneous response to queries , and reduces the network communication to the data download time . in comparison with th e geolibrary model, igdc is missing the gazetteer . this component can help improve the ease of user navigation through a geospatial data collection. the other useful component includes online mapping and spatial data visualization services. the idea of such services is to provide the user with a simple-tooperate mapping tool for visualizing and exploring the results of user-run queries . one such service, currently under implementation at igdc, includes thematic mapping of economic and demographic variables for idaho using descartes software .16 descartes is a knowledgebased system supporting users in the design and utilization of thematic maps. the knowledge base incorporates domain-independent visualization rules determining which map presentation technique to employ in response to the user selection of variables. an intelligent is this a geolibrary? i jankowska and jankowski 9 reproduced with permission of

rare and unique items have been made available online for research through the university of houston (uh) digital library. six years later, the uh libraries’ new digital initiatives call for a more dynamic digital repository infrastructure that is extensible, scalable, and interoperable. the uh libraries’ mission and the mandate of its strategic directions drives the pursuit of seamless access and expanded digital collections. to answer the calls for technological change, the uh libraries administration appointed a digital asset management system (dams) implementation task force to explore, evaluate, test, recommend, and implement a more robust digital asset management system. this article focuses on the task force’s dams selection activities: needs assessment, systems evaluation, and systems testing. the authors also describe the task force’s dams recommendation based on the evaluation and testing data analysis, a comparison of the advantages and disadvantages of each system, and system cost. finally, the authors outline their dams implementation strategy comprised of a phased rollout with the following stages: system installation, data migration, and interface development. introduction since the launch of the university of houston digital library (uhdl) in 2009, the uh libraries have made tens of thousands of rare and unique items available online for research using contentdm. as we began to explore and expand into new digital initiatives, we realize that the uh libraries’ digital aspirations require a more dynamic, flexible, scalable, and interoperable digital asset management system that can manage larger amounts of materials in a variety of formats. we plan to implement a new digital repository infrastructure that accommodates creative workflows and allows for the configuration of additional functionalities such as digital exhibits, data mining, cross-linking, geospatial visualization, and multimedia presentation. the annie wu (awu@uh.edu) is head of metadata and digitization services, santi thompson (sathompson3@uh.edu) is head of repository services, rachel vacek (evacek@uh.edu) is head of web services, sean watkins (slwatkins@uh.edu) is web projects manager, and andrew weidner (ajweidner@uh.edu) is metadata services coordinator, university of houston libraries. mailto:awu@uh.edu mailto:sathompson3@uh.edu mailto:evacek@uh.edu

doi:10.6017/ital.v35i2.9152 6 new system will be designed with linked data in mind and will allow us to publish our digital collections as linked open data within the larger semantic web environment. the uh libraries strategic directions set forth a mandate for us to “work assiduously to expand our unique and comprehensive collections that support curricula and spotlight research. we will pursue seamless access and expand digital collections to increase national recognition.”1 to fulfill the uh libraries’ mission and the mandate of our strategic directions, the uh libraries administration appointed a digital asset management system (dams) implementation task force to explore, evaluate, test, recommend, and implement a more robust digital asset management system that would provide multiple modes of access to the uh libraries’ unique collections and accommodate digital object production at a larger scale. the collaborative task force comprises librarians from four departments: metadata and digitization services (mds), web services, digital repository services, and special collections. the core charge of the task force is to: • perform a needs assessment and build criteria and policies based on evaluation of the current system and requirements for the new dams • research and explore dams on the market and identify the top three systems for beta testing in a development environment • generate preliminary recommendations from stakeholders' comments and feedback • coordinate installation of the new dams and finish data migration • communicate the task force work to uh libraries colleagues literature review libraries have maintained dams for the publication of digitized surrogates of rare and unique materials for over two decades. during that time, information professionals have developed evaluation strategies for testing, comparing, and evaluating library dams software. reviewing these models and associated case studies provided insight into common practices for selecting systems and informed how the uh libraries dams implementation task force conducted its evaluation process. one of the first publications of its kind, “a checklist for evaluating open source digital library software” by dion hoe-lian goh et al., presents a comprehensive list of criteria for library dams evaluation.2 the researchers developed twelve broad categories for testing (e.g., content management, metadata, and preservation) and generated a scoring system based on the assignment of a weight and a numeric value to each criterion.3 while the checklist was created to assist with the evaluation process, the authors note that an institution’s selection decision should be guided primarily by defining the scope of their digital library, the content being curated using the software, and the uses of the material.4 through their efforts, the authors created a rubric that can be utilized by other organizations when selecting a dams. information technology and libraries | june 2016 7 subsequent research projects have expanded upon the checklist evaluation model. in “choosing software for a digital library,” jody deridder outlines major issues that librarians should address when choosing dams software, including many of the hardware, technological, and metadata concerns that goh et al. identified.5 additionally, she emphasizes the need to account for personnel and service requirements with a variety of activities: usability testing and estimating associated costs; conducting a formal needs assessment to guide the evaluation process; and a tiered-testing approach, which calls upon evaluators to winnow the number of systems.6 by considering stakeholder needs, from users to library administrators, deridder’s contributions inform a more comprehensive dams evaluation process. in addition to creating evaluation criteria, the literature on dams selection has also produced case studies that reflect real-world scenarios and identify use cases that help determine user needs and desires. in “evaluation of digital repository software at the national library of medicine,” jennifer l. marill and edward c. luczak discuss the process that the national library of medicine (nlm) used to compare ten dams, both proprietary and open-source.7 echoing goh et al. and deridder, marill and luczak created broad categories for testing and developed a scoring system for comparing dams.8 additionally, marill and luczak enriched the evaluation process by implementing two testing phases: “initial testing of ten systems” and “in-depth testing of three systems.”9 this method allowed nlm to conduct extensive research on the most promising systems for their needs before selecting a dams to implement. the tiered approach appealed to the task force, and influenced how it conducted the evaluation process, because it balances efficiency and comprehensiveness. in another case study, dora wagner and kent gerber describe the collaborative process of selecting a dams across a consortium. in their article “building a shared digital collection: the experience of the cooperating libraries in consortium,”10 the authors emphasize additional criteria that are important for collaborating institutions: the ability to brand consortial products for local audiences; the flexibility to incorporate differing workflows for local administrators; and the shared responsibility of system maintenance and costs.11 while the uh libraries will not be managing a shared repository dams, the task force appreciated the article’s emphasis on maximizing customizations to improve the user experience. in “evaluation and usage scenarios of open source digital library and collection management tools,” georgios gkoumas and fotis lazarinis describe how they tested multiple open-source systems against typical library functions—such as acquisitions, cataloging, digital libraries, and digital preservation—to identify typical use cases for libraries.12 some of the use cases formulated by the researchers address digital platforms, including features related to supporting a diverse array of metadata schema and using a simple web interface for the management of digital assets.13 these use cases mirror local feature and functionality requests incorporated into the uh libraries’ evaluation criteria. hitting the road towards a greater digital destination: evaluating and testing dams at university of houston libraries | wu et al. | doi:10.6017/ital.v35i2.9152 8 in “digital libraries: comparison of 10 software,” mathieu andro, emmanuelle asselin, and marc maisonneuve discuss a rubric they developed to compare six open-source platforms (invenio, greenstone, omeka, eprints, ori-oai, and dspace) and four proprietary platforms (mnesys, digitool, yoolib, and contentdm) around six core areas: document management, metadata, engine, interoperability, user management, and web 2.0. 14 the authors note that each solution is “of good quality” and that institutions should consider a variety of factors when selecting a dams, including the “type of documents you will want to upload” and the “political criteria (open source or proprietary software)” desired by the institution.15 this article provided the uh libraries with additional factors to include in their evaluation criteria. finally, heather gilbert and tyler mobley’s article “breaking up with contentdm: why and how one institution took the leap to open source,” provides a case study for a new trend: selecting a dams for migration from an existing system to a new one.16 the researchers cite several reasons for their need to select a new dams, primarily their current system’s limitations with searching and displaying content in the digital library.17 they evaluated alternatives and selected a suite of open-source tools, including fedora, drupal, and blacklight, which combine to make up their new dams.18 gilbert and mobley also reflect on the migration process and identify several hurdles they had to overcome, such as customizing the open-source tools to meet their localized needs and confronting inconsistent metadata quality.19 gilbert and mobley’s article most closely matches the scenario faced by the uh libraries. our study adds to the limited literature on evaluating and selecting dams for migration in several ways. it demonstrates another model that other institutions can adapt to meet their specific needs. it identifies new factors for other institutions to take into account before or during their own migration process. finally, it adds to the body of evidence for a growing movement of libraries migrating from proprietary to open-source dams. dams evaluation and analysis methodology needs assessment the dams implementation task force fulfilled the first part of its charge by conducting a needs assessment. the goal of the needs assessment was to collect the key requirements of stakeholders, identify future features of the new dams, and gather data in order to craft criteria for evaluation and testing in the next phase of its work. the task force employed several techniques for information gathering during the needs assessment phase: • identified stakeholders and held internal focus group interviews to identify system requirement needs and gaps • reviewed scholarly literature on dams evaluation and migration • researched peer/aspirational institutions • reviewed national standards around dams information technology and libraries | june 2016 9 • determined both the current use of uhdl as well as its projected use of uhdl • identified uhdl materials and users task force members took detailed notes during each focus group interview session. the literature research on dams evaluation helped the task force to find articles with comprehensive dams evaluation criteria. the niso criteria for core types of entities in digital library collections were also listed and applied to the evaluation after reviewing the niso framework of guidance for building good digital collections.20 more than forty peer and aspirational institutions’ digital repositories were benchmarked to identify web site names, platform architecture, documentation, and user and system features. the task force analyzed the rich data gathered from needs assessment activities and built the dams evaluation criteria that prepared the task force for the next phase of evaluation. evaluation, testing, and recommendation the task force began its evaluation process by identifying twelve potential dams for consideration that were ultimately narrowed down to three systems for in-depth testing. using data from focus group interviews, literature reviews, and dams best practices, the group generated a list of benchmark criteria. these broad evaluation criteria covered features in categories of system functionality, content management, metadata, user interface, and search support. members of the task force researched dams documentation, product information, and related literature to score each system against the evaluation criteria. table 1 contains the scores of the initial evaluation. from this process, five systems emerged with the highest scores: ● fedora (and, closely associated, fedora/hydra and fedora/islandora) ● collective access ● dspace ● rosettacontentdm the task force eliminated collective access from the final systems for testing because of its limited functionality. it is based around archival content only, and is not widely deployed. the task force decided not to test contentdm because of the system’s known functionalities that we identified through firsthand experience. after the initial elimination process, fedora (including fedora/hydra and fedora/islandora), dspace, and rosetta remained for in-depth testing. hitting the road towards a greater digital destination: evaluating and testing dams at university of houston libraries | wu et al. | doi:10.6017/ital.v35i2.9152

literature review, and best practices. while the broad evaluation focused on high-level functions, the detailed evaluation and testing criteria for the final three systems closely analyzed the specific features of each dams in eight categories: ● system environment and function ● administrative access ● content ingest and management ● metadata ● content access ● discoverability ● report and inquiry capabilities ● system support * total possible score: 29. † removed from evaluation because the system does not support dublin core metadata. ‡ removed from evaluation because the system does not support dublin core metadata. information technology and libraries | june 2016 11 prior to the in-depth testing of the final three systems, the task force researched timelines for system setup. rosetta’s timeline for system setup proved to be prohibitive. consequently, the task force eliminated rosetta from the testing pool and moved forward with fedora and dspace. to conduct the detailed evaluation, the task force scored the specific features under each category utilizing systems testing and documentation. a score range from zero to three (0 = none, 1 = low, 2 = moderate, 3 = high) was assigned for each feature evaluated. after evaluating all features, the score was tallied for each category. our testing revealed that fedora outperformed dspace in over half of the testing sections: content ingest and management, metadata, content access, discoverability, and report and inquiry capabilities. see table 2 for the tallied scores in each testing section. testing sections

review of the testing results, the task force conducted a facilitated activity to summarize the advantages and disadvantages of each system. based on this comparison, the dams task force recommended that the uh libraries implement a fedora/hydra repository architecture with the following course of action: ● adapt the uhdl user interface to fedora and re-evaluate it for possible improvements ● develop an administrative content management interface with the hydra framework ● migrate all uhdl content to a fedora repository hitting the road towards a greater digital destination: evaluating and testing dams at university of houston libraries | wu et al. | doi:10.6017/ital.v35i2.9152 12 fedora/hydra advantages fedora/hydra disadvantages open source steep learning curve large development community long setup time linked data ready requires additional tools for discovery modular design through api no standard model for multi-file objects scalable, sustainable, and extensible batch import/export of metadata handles any file format table 3. fedora/hydra advantages and disadvantages the primary advantages of a dams based on fedora/hydra are: a large and active development community; a scalable and modular system that can grow quickly to accommodate large scale digitization; and a repository architecture based on linked data technologies. this last advantage, in particular, is unique among all systems evaluated, and will give the uh libraries the ability to publish our collections as linked open data. fedora 4 conforms to the world wide web consortium (w3c) recommendation for linked data platforms.21 the main disadvantage of a fedora/hydra system is the steep learning curve associated with designing metadata models and developing a customized software suite, which translates to a longer implementation time compared to off-the-shelf products. the uh libraries must allocate an appropriate amount of time and resources for planning, implementation, and staff training. the long-term return on investment for this path will be a highly skilled technical staff with the ability to maintain and customize an open-source, standards-based repository architecture that can be expanded to support other uh libraries content such as geospatial data, research data, and institutional repository materials. information technology and libraries | june 2016 13 dspace advantages dspace disadvantages open source flat file and metadata structure easy installation / ready out of box limited reporting capabilities existing familiarity through texas digital library limited metadata features user group / profile controls does not support linked data metadata quality module limited api batch import of objects not scalable / extensible poor user interface table 4. dspace advantages and disadvantages the main advantages of dspace are ease of installation, familiarity of workflows, and additional functionality not found in contentdm.22 installation and migration to a dspace system would be relatively fast, and staff could quickly transition to new workflows because they are similar to contentdm. dspace also supports authentication and user roles that could be used to limit content to the uh community only. commercial add-on modules, although expensive, could be purchased to provide more sophisticated content management tools than are currently available with contentdm. the disadvantages of a dspace system are the same long-term, systemic problems with the current contentdm repository. dspace uses a flat metadata structure, has a limited api, does not scale well, and is not customizable to the uh libraries’ needs. consultations with peers indicated that both contentdm and dspace institutions are exploring the more robust capabilities of fedora-based systems. migration of the digital collections in contentdm to a dspace repository would provide few, if any, long term benefits to the uh libraries. of all the systems considered, implementation of a fedora/hydra repository aligns most clearly with the uh libraries strategic directions of attaining national recognition and improving access to our unique collections. the fedora and hydra communities are very active, with project management overseen by duraspace and hydra respectively.23,24 over the long term, a repository based on fedora/hydra will give the uh libraries a low cost, scalable, flexible, and interoperable platform for providing online access to our unique collections. hitting the road towards a greater digital destination: evaluating and testing dams at university of houston libraries | wu et al. | doi:10.6017/ital.v35i2.9152 14 cost considerations to balance the current digital collections production schedule with the demands of a timely implementation and migration, the task force identified the following investments as cost effective for fedora/hydra and dspace, respectively: fedora/hydra dspace metadata librarian: annual salary ● manages daily metadata unit operations during implementation ● streamlines the migration process metadata librarian: annual salary ● manages daily metadata unit operations during implementation ● streamlines the migration process @mire modules: $41,500 ● content delivery (3): $13,500 ● metadata quality: $10,000 ● image conversion suite: $9,000 ● content & usage analysis: $9,000 ● these modules require one-time fees to @mire that recur when upgrading to a new version of dspace table 5. start-up costs associated with fedora/hydra and dspace the task force determined that an investment in one librarian’s salary is the most cost-effective course of action. the new metadata librarian will manage daily operations of the metadata unit in metadata & digitization services while the metadata services coordinator, in close collaboration with the web projects manager, leads the dams implementation process. in contrast to fedora, migration to dspace would require a substantial investment in third party software modules from @mire to deliver the best possible content management environment and user experience. implementation strategies the implementation of the new dams will occur in a phased rollout comprised of the following stages: system installation, data migration, and interface development. mds and web services will perform the majority of the work, in consultation with key stakeholders from special collections and other units. throughout this process, the dams implementation task force will information technology and libraries | june 2016 15

collections and other key stakeholders. the dams task force will consult with the digital preservation task force† to determine how closely the preservation and access systems will be integrated and at what points. the two groups will also jointly outline a dams migration strategy that aligns with the preservation system. web services and mds will collaborate on research and development of an

doi:10.6017/ital.v35i2.9152 16 phase two: data migration in the second phase, mds will migrate legacy content from contentdm to the new system and work with web services, special collections, and the architecture and art library to resolve any technical, metadata, or content problems that arise. the second phase will begin with the development of a strategy for completing the work in a timely fashion, followed by migration of representative sample collections to the new system to test and refine its capabilities. after testing is complete, all legacy content will be migrated from contentdm to fedora, and preservation metadata for migrated collections will be created and archived. development work on the hydra administrative interface will also continue. after the data migration is complete, all new collections will be ingested into fedora/hydra, and the current contentdm installation will be retired. phase three: interface development in the final phase, web services will reevaluate the current front-end user interface (ui) for the uhdl by conducting user tests to better understand how and why users are visiting the uhdl. web services will also analyze web and system analytics and gather feedback from special collections and other stakeholders. depending on the outcome of this research, web services may create a new ui based on the hydra framework or choose to update the current front-end application with modifications or new features. web services and mds will also continue to develop or adopt tools for the management of uhdl content and work with special collections and the branch libraries to establish production workflows in the new system. continued development work on the front-end and administrative interfaces, for the life of the new digital asset management system, is both expected and desirable as we maintain and improve the uhdl infrastructure and contribute to the open source software community in line with the uh libraries strategic directions. ongoing: assessment, enhancement, training, and documenting throughout the transition process mds and web services will undergo extensive training in workshops and conferences to develop the skills necessary for developing and maintaining the new system. they will also establish and document workflows to ensure the long-term viability of the system. regular consultation with special collections, the branch libraries, and other stakeholders will be conducted to ensure that the new system satisfies the requirements of colleagues and patrons. ongoing activities will include: ● assessing service impact of new system ● user testing on ui ● regular system enhancements ● establishing new workflows ● creating and maintaining documentation ● training: conferences, webinars, workshops, etc. information technology and libraries | june 2016 17 conclusion transitioning from contentdm to a fedora/hydra repository will place the uh libraries in a position to sustainably grow the amount of content in the uh digital library and customize the uhdl interfaces for a better user experience. publishing our data in a linked data platform will give the uh libraries the ability to more easily publish our data for the semantic web. in addition, the fedora/hydra architecture can be adapted to support a wide range of uh libraries projects, including a geospatial data portal, a research data repository, and a self-deposit institutional repository. over the long term, the return on investment for implementing an open-source repository architecture based on industry standard software will be: improved visibility of our unique collections on the web; expanded opportunities for aggregating our collections with highprofile repositories such as the digital public library of america; and increased national recognition for our digital projects and staff expertise. references 1. “the university of houston libraries strategic directions, 2013–2016,” accessed july 22, 2015,

well as their professional life. facing many challenges of division in all aspects (social distancing, political and social divisions, remote work environments), university of south florida libraries took the lead in exploring how to overcome these various separations by providing access to its high-quality information sources to its local community and beyond. this paper shares the insights of using linked data technology to provide easy access to digital cultural heritage collections not only for the scholarly communities but also for those underrepresented user groups. the authors present the challenges at this special time of the history, discuss the possible solutions, and propose future work to further the effort. introduction we are living in a time of division. many of us are adjusting to a new reality of working separated from our colleagues and the institutions that formerly brought us together physically and socially due to covid-19. even if we can work in the same physical locale, we are careful and distant with each other. our expressions are covered by masks, and we take pains with hygiene that might formerly have felt offensive. but the largest divisions and challenges being faced in the united states go beyond our physical separation. the nation has been rocked and confronted by racial inequality in the form of black lives matter, a divisive presidential campaign, income inequality exacerbated by covid-19, the continued reckoning with the #metoo movement, and the wildfires burning the west coast. it feels like we are burning both literally and metaphorically as a country. adding fuel to this fire is the consumption of unreliable information. ironically, even as our divisions become more extreme, we are increasingly more connected and tuned into news via the internet. sadly, fact checking and sources are few and far between on social media platforms, where many are getting their information. the pew foundation report the future of truth and misinformation online warns that we are on the verge of a very serious threat to the democratic process due to the prevalence of false information. lee raine, director of the pew research center’s internet and technology project, warns, “a key tactic of the new anti-truthers is not so much to get people to believe in false information. it’s to create enough doubt that people will give up trying to find the truth, and distrust the institutions trying to give them the truth.”1 libraries and other cultural institutions have moved very quickly to address and educate their populations and the community at large, trying to give a voice to the oppressed and provide information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 2 reliable sources of information. the university of south florida (usf) libraries reacted by expanding antiracism holdings. usf’s purchases were informed by work at other institutions, such as the university of minnesota’s antiracism reading lists, which has in turn grown into a rich resource that includes other valuable resources like the mapping prejudice project and a link to the umbra search.2 the triad black lives matter protest collection at the university of north carolina greensboro is another example of a cultural institution reacting swiftly to document, preserve, and educate.3 these new pages and lists being generated by libraries and cultural institutions seem to be curated by hand using tools that require human intervention to make them and keep them up to date. this is also a challenge the usf libraries faced when constructing its new african american experience in florida portal, a resource that leverages already existing digital collections at usf to promote social justice. another key challenge is linking new digital collections and tools to already established collections and holdings. beyond the new content being created in reaction to current movements, there is already a wealth of information established in rich archives of material, especially regarding african american history. digital collections need to be discoverable by a wide audience to achieve resource sharing and educational purposes. this is a challenge many digital collections struggle with, because they are often being siloed from library and archival holdings even within their own institutions. all the good information in the world is not useful if it is not findable. an example of a powerful discovery tool that is difficult to find and use is the umbra search (https://www.umbrasearch.org/) linked to the university of minnesota’s anti-racism reading list. umbra search is a tool that aggregates content from more than 1,000 libraries, archives, and museums.4 it is also supported by highprofile grants from the institute of museum and library services, the doris duke charitable foundation, and the council on library and information resources. however, the website is difficult to find in a web search. umbra search was named after society of umbra, a collective of black poets from the 1960s. the terms umbra and society of umbra do not return useful results for finding the portal, nor do broader searches of african american history the portal is difficult to find through basic web searches. one of the few chances for a user to find the site is if they came upon the human-made link in the university of minnesota anti-racism reading list. despite enthusiasm from libraries and other cultural institutions, new purchases and curated content are not going to reach the world as fully as hoped. until libraries adopt open data formats in favor of locking away content in closed records like marc, library and digital content will remain siloed from the internet. the library catalog and digital platforms are even siloed from each other. we make records and enter metadata that is fit for library use but not shareable to the web. as karen coyle asked in her lita keynote address a decade ago, the question is how can libraries move from being “on the web” to being “of the web”?5 the suggested answer and the answer the usf libraries are researching is with linked data. literature review the literature on linked data for libraries and cultural heritage resources reflects an implementation that is “gradual and uneven.” as national libraries across the world and the library of congress develop standards and practices, academic libraries are still trying to understand their role in implementation and identify their expertise.6 information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 3 in 2006 tim berners-lee, the creator of the sematic web concept, outlined four rules of linked data: 1. use uris as names for things. 2. use http uris so that people can look up those names. 3. when someone looks up a uri, provide useful information, using the standards (rdf, sparql). 4. include links to other uris so that they can discover more things.7 it was not too long after this that large national libraries began exploring linked data and experimenting with uses. in 2010 the british library presented its prototype of linked data. this move was made in accordance with the uk government’s commitment to transparency and accountability along with the user’s expectation that the library would keep up with cutting edge trends.8 today the british library has released the british national bibliography as linked data instead of the entire catalog because it is authoritative and better maintained than the catalog.9 the national libraries of europe, spurred on by government edicts and europeana (https://www.europeana.eu/en), are leading the progress in implementation of linked data. national libraries are uniquely suited to the development and promotion of new technologies because of their place under the government and proximity to policy making, bridging communication between interested parties and the ability to make projects into sustainable services.10 a 2018 survey of all european national libraries found that 15 had implemented linked data, two had taken steps for implementation and three intended to implement it. even national libraries that were unable to implement linked data were contributing to the linked data open cloud by providing their data in datasets to the world.11 part of the difficulty with earlier implementation of linked data by libraries and cultural heritage institutions was the lack of a “killer example” that libraries could emulate.12 the relatively recent success of european national libraries might provide those examples. many other factors have slowed the implementation of linked data. a survey of norwegian libraries in 2009 found considerable gap in the semantic web literature between the research undertaken in the technological field and the research in the socio-technical field. implementing linked data requires reorganization of the staff, commitment of resources, education throughout the library and buy-in from the leadership to make it strategically important.13 the survey of european national libraries cited the exact same factors as limitations in 2018.14 outside of european national libraries the implementation of linked data has been much slower. many academic institutions have taken on projects that tend to languish in a prototype or proof of concept phase.15 the library-centric talis group of the united kingdom “embraced a vision of developing an infrastructure based on semantic web technologies” in 2006, but abandoned semantic web-related business activities in 2012.16 it has been suggested that it is premature to wholly commit to linked data, but it should be used for spin-off projects in an organization for experimentation and skill development.17 linked data is also still proving to be technologically challenging for implementation of cultural heritage aggregators. if many human resources are needed to facilitate linked data, it will remain an obstacle for cultural heritage aggregators. a study has shown automated interpretation of information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 4 ontologies is hampered by a lack of inter-ontology relations. cross-domain applications will not be able to use these ontologies without human intervention.18 aiding in the development and awareness of linked data practices for libraries is the creation and implementation of bibframe by the library of congress. the library of congress’s announcement in july 2018 that bibframe would be the replacement of marc definitively shows that the future of library records is focused on linking out and integrating into the web.19 the new rda (resource description and access) cataloging standards made it clear that marc is no longer the best encoding language for making library resources available on the web.20 while rda has adopted the cataloging rules to meet a variety of new library environments, the marc encoding language makes it difficult for computers to interpret and apply logic algorithms to the marc format. in response, the library of congress commissioned the consulting agency zepheria to create a framework that would integrate with the web and be flexible enough to work with various open formats and technologies, as well as be able to adapt to change. using the principles and technologies of the open web, the bibframe vocabulary is made of “resource description framework (rdf) properties, classes, and relationships between and among them.”21 eric miller, the ceo of zepheria, says bibframe “works as a bridge between the description component and open web discovery. it is agnostic with regards to which web discovery tool is employed” and though we cannot predict every technology and application bibframe can “rely on the ubiquity and understanding of uris and the simple descriptive power of rdf.”22 the implementation of linked data in the cultural heritage sphere has been erratic but seems to be moving forward. it is important to pursue though because bringing local data out of the “deep web” and making them open and universally accessible, means offering minority cultures a democratic opportunity for visibility.”23 linked data linked data is one way to increase the access and discoverability of critical digital cultural heritage collections. also referred to as semantic web technologies, linked data follows the w3c resource description framework (rdf) standards.24 according to tim berners-lee, the semantic web will bring structure and well-defined meaning to web content allowing computers to perform more automated processes.25 by providing structure and meaning to digital content, information can be more readily and easily shared between institutions. this provides an opportunity for digital cultural heritage collections of underrepresented populations to get more exposure on the web. following is a brief overview of linked data to illustrate how semantic web technologies function. linked data is created by forming semantic triples. each rdf triple contains uniform resource identifiers or uris. these identifiers allow computers (machines) to “understand” and interpret the metadata. each rdf triple consists of three parts: a subject, a predicate, and an object. the subject defines what the metadata rdf triple is about, while the object contains information about the subject which is further defined by the relationship link in the predicate. information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 5 figure 1. example of a linked data rdf triple describing william shakespeare’s authorship of hamlet. for example, in figure 1, “william shakespeare wrote hamlet” is a triple. the subject and predicate of the triple are written as an uri containing the identifier information and the object of the triple is a literal piece of information. the subject of the triple, william shakespeare, has an identifier which in this example links to the library of congress name authority file for william shakespeare. the predicate of the rdf triple describes the relationship between the subject and object. the predicate also typically defines the metadata schema being used. in this example, dublin core is the metadata schema being used, so “wrote” would be identified by the dublin core creator field. the object of this semantic triple, hamlet, is a literal. literals are text that are not linked because they do not have a uri. subjects and predicates always have uris to allow the computer to make links. the object may have a uri or be a literal. together these uris, along with the literal, tell the computer everything it needs to know about this piece of metadata, making it self-contained. rdf triples with their uris are stored in a triple-store graph style database which functions differently from a typical relational database. relational databases rely on table headers to define the metadata stored inside. moving data between relational databases can be complex because tables must be redefined every time data is moved. graph databases don’t need tables since all the defining information is already stored in each triple. this allows for bidirectional flow of information between pieces of metadata and makes transferring data simpler and more efficient.26 information in a triple-store database is then retrieved using sparql, a query language developed for linked data. because linked data is stored as self-contained triples, machines have all the information needed to process the data and perform advanced reasoning and logic programming. this leads to better search functionality and lends itself well to artificial intelligence (ai) technologies. many of today’s modern websites make use of these technologies to enhance their displays and provide greater functionality for their users. the internet is an excellent avenue for libraries to un-silo their collections and make them globally accessible. once library collections are on the web, advanced keyword search functionalities and artificial intelligence machine learning algorithms can be developed to automate metadata creation workflows and enhance search and information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 6 retrieval of library resources. the use of linked data metadata in these machine-learning functions will add a layer of semantic understanding to the data being processed and analyzed for patron discovery. ai technology can also be used to create advanced graphical displays making connections for patrons between various resources on a research topic. sharing digital cultural heritage data with other institutions often involves transferring data and is considered one of the greatest difficulties in sharing digital collections. for example, if one institutional repository uses dublin core to store its metadata for a certain cultural heritage collection and another repository uses mods/mets to store digital collections, there must first be a data conversion before the two repositories could share information. dublin core and mods/mets are two completely different schemas with different fields and metadata standards. these two schemas are incompatible with each other and must be crosswalked into a common schema. this typically results in some data loss during the transformation process. this makes combining two collections from different institutions into one shared web portal difficult. linked data allows institutions to share collections more easily. because linked data triples are self-contained, there is no need to crosswalk metadata stored in triples from one schema into another when transferring data. the uris contained in the rdf triples allow the computer to identify the metadata schema and process the metadata. rdf triples can be harvested from one linked data system and easily placed into another repository or web portal. a variety of schemas can all be stored together in one graph database. storing metadata in this way increases the interoperability of digital cultural heritage collections. collections stored in triple-store databases have sparql endpoints that make harvesting the metadata in a collection more efficient. libraries can easily share metadata on important collections increasing the exposure and providing greater access for a wider audience. philip schreur, author of “bridging the worlds of marc and linked data,” sums this concept up nicely: “the shift to the web has become an inextricable part of our day-to-day lives. by moving our carefully curated metadata to the web, libraries can offer a muchneeded source of stable and reliable data to the rapidly growing world of web discovery.”27 linked data also makes it easier to harvest metadata and import collections into larger cultural heritage repositories like digital public library of america (dpla) which uses linked data to “empower people to learn, grow, and contribute to a diverse and better-functioning society by maximizing access to our shared history, culture, and knowledge.”28 europeana, the european cultural heritage database, uses semantic web technologies to support its mission which is to “empower the cultural heritage sector in its digital transformation.”29 using linked data to transfer data into these national repositories is more efficient and there is less loss of data because the triples do not have to be transformed into another schema. this increases the access of many cultural heritage collections that might not otherwise be seen. one of the big advantages to linked data is the ability to create connections between other cultural heritage collections worldwide via the web. incorporating triples harvested from other collections into the local datasets enables libraries to display a vast amount of information about cultural heritage collections in their web portals. libraries thus can provide a much richer display and allows users access to a greater variety of resources. linked data also allows web developers to use uris to implement advanced search technologies creating a multifaceted search environment for patrons. current research points to the fact that using sematic web technologies makes the creation of advance logic and reasoning functionalities possible. according to liyang yu in the book introduction to the semantic web and semantic web services, “the semantic web is an information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 7 extension of the current web. it is constructed by linking current web pages to a structured data set that indicates the semantics of this linked page. a smart agent, which is able to understand this structure data set, will then be able to conduct intelligent actions and make educated decisions on a global scale.”30 many digital cultural heritage collections in libraries live in siloed resources and are therefore only accessible to a small population of users. linked data helps to break down traditional library silos in these collections. by using linked data, an institution can expand the interoperability of the collection and make it more easily accessible. many institutions are starting to incorporate linked data technologies into digital collections, thereby increasing the ability for institutions to share collections. this allows for a greater audience to have access to critical cultural heritage collections for underrepresented populations. in the article “bridging the worlds of marc and linked data,” the author states, “the shift to linked data within this closed world of library resources will bring tremendous advantages to discovery both within a single resource … as well as across all the resources in your collections, and even across all of our collective collections. but there are other advantages to moving to linked data. through the use of linked data, we can connect to other trusted sources on the web.… we can also take advantage of a truly international web environment and reuse metadata created by other national libraries.”31 university of south florida libraries practice university of south florida libraries digital collections house a rich collection varying from cultural heritage objects to natural science and environment history materials to collections related to underrepresented populations. most of the collections are unique to usf and have significant research and educational value. the library is eager to share the collections as widely as possible and hopes the collections can be used at both document and data level. linked data creates a “web of data” instead of a “web of documents,” which is the key to bringing structure and meaning to web content, allowing computers to better understand the data. however, collections are mostly born at the document level. therefore, the first problem librarians need to solve is how to transform the documents to data. for example, there is a beautiful natural history collection called audubon florida tavernier research papers in usf libraries digital collections. the audubon florida tavernier research papers is an image collection which includes rookeries, birds, people, bodies of water, and man-made structures. the varied images come from decades of research and are a testament to the interconnectedness of bird population health and human interaction with the environment. the images reflect the focus of audubon’s work in research and conservation efforts both to wildlife and to the habitat that supports the wildlife.32 this was selected to be the first collection the authors experimented with to implement linked data at usf libraries. the lessons learned from working with this collection are applied to later work. when the collection was received to be housed in the digital platform, it was carefully analyzed to determine how to pull the data out of all the documents as much as possible. the authors designed a metadata schema of the combination of mods and darwin core (darwin core, abbreviated to dwc, is an extension of dublin core for biodiversity informatics) to pull out and properly store the data. information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 8 figure 2. american kestrel. figure 3. american kestrel metadata. information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 9 figure 2 is one of the documents in the collection, which is a photo of an american kestrel. figure 3 shows the data collected from the document and the placement of the data in the metadata schema. the authors put the description of the image in free text in the abstract field. this field is indexed and searchable through the digital collections platform. location information is put in the hierarchical spatial field. the subject heading fields describe the “aboutness” of the image, that is, what is in the image. all the detailed information about the bird is placed in darwin core fields. thus, the document is dissembled into a few pieces of data which are properly placed into metadata fields where they can be indexed and searched. having data alone is not sufficient to meet linked data requirements. the first of the four rules of linked data is to name things using uris.33 to add uris to the data, the authors needed to standardize the data and reconcile it against widely-used authorities such as library of congress subject headings, wikidata, and the getty thesaurus of geographic names. standardized data tremendously increases the percentage of data reconciliation, which will lead to more links with related data once published. figure 4. amenaprkitch khachkar. figure 4 shows an example from the armenia heritage and social memory program. this is a visual materials collection with photos and 3d digital models. it was created by the digital heritage and humanities collection team at the library. the collection brings together comprehensive information and interactive 3d visualization of the fundamentals of armenian identity, such as their architectures, languages, arts, etc.34 when preparing the metadata for the items in this collection, the authors devoted extra effort to adding geographic location metadata. this effort serves two purposes: one is to respectfully and honestly include the information in the collection; and the second is to provide future reference to the location of each item as the physical items are in danger and could disappear or be ruined. the authors employed the getty thesaurus of geographic names because it supports a hierarchical location structure. the location names at each level can be reconciled and have their own uris. the authors also paid extra attention on the subject headings. figure 5 shows how the authors used library of congress subject headings, local subject headings assigned by the researchers, and the getty art and architecture thesaurus for this collection. in the data reconciliation stage, the metadata can be compared against both library of congress subject headings authority files and the getty aat vocabularies so that as many uris as possible can be fetched and added to the metadata. the focus information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 10 on geographic names and subject headings is to standardize the data and use controlled vocabularies as much as possible. once moving to the linked data world, the data will be ready to be added with uris. therefore, the data can be linked easily and widely. figure 5. amenaprkitch khachkar metadata. information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 11 one of the goals of building linked data is to make sense out of data and to generate new knowledge. as the librarians explored how to bring together multiple usf digital collections to highlight african american history and culture, three collections seemed particularly appropriate: • an african american sheet music collection from the early 20th century (https://digital.lib.usf.edu/sheet-music-aa) • the “narratives of formerly enslaved floridians” collection from 1930s (https://digital.lib.usf.edu/fl-slavenarratives) • the “otis r. anthony african american oral history collection” from 19781979(https://digital.lib.usf.edu/ohp-otisanthony) these collections are all oral expressions of african american life in the us. they span the first three-quarters of the 20th century around the time of the civil rights movement. creating linked data out of these collections will help shed light on the life of african americans through the 20th century and how it related to the civil rights movement. with semantic web technology support, these collections can be turned into machine actionable datasets to assist research and education activities on racism, anti-racism and to piece into the holistic knowledge base. usf libraries started to partner with dpla in 2018. dpla leverages linked data technology to increase discoverability of the collections contributed to it. dpla employs javascript object notation for linked data (json-ld) as its serialization for their data which is in rdf/xml format. json-ld has a method of identifying data with iris. the use of this method can effectively avoid data ambiguity considering dpla is holding a fairly large amount of data. json-ld also provides computational analysis in support of semantics services which enriches the metadata and in results, the search will be more effective.35 in the 18 months since usf began contributing selected digital collections to dpla, usf materials have received more than 12,000 views. it is exciting to see the increase in the usage of the collections and it is the hope that they will be accessed by more diverse user groups. usf libraries are exploring ways to scale up the project and eventually transition all the existing digital collections metadata to linked data. one possible way of achieving this goal would be through metadata standardization. a pilot project at usf libraries is to process one medium-size image collection of 998 items. the original metadata is in mods/mets xml files. we first decided to use the dpla metadata application profile as the data model. if the pilot project is successful, we will apply this model to all of our linked data transformation processes. in our pilot, we are examining the fields in our mods/mets metadata and identify those that will be meaningful in the new metadata schema. then we transport the metadata in those fields to excel files. the next step is to use openrefine to reconcile the data in these excel files to fetch uris for exact match terms. during this step, we are employing reconciliation services from the library of congress, getty tgn, and wikidata. after all the metadata is reconciled, we are transforming the excel file to triples. the column headers of the excel file become the predicates and the metadata as well as their uris will be the objects of the triples. next, these triples will be stored in an apache jena triple-store database so that we can start designing sparql queries to facilitate search. the final step will be designing a user-friendly interface to further optimize the user experiences. in this process, to make the workflow as scalable as possible, we are focusing on testing two processes: first, creating a universal metadata application profile to apply to the most, if not all, of the collections; and second, only fetching uris for exactly matching terms during the reconciliation information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 12 process. both of these processes aim to reduce human interactions with the metadata so that the process is more affordable to the library. conclusion and future work linked data can help collection discoverability. in the past six months, usf has seen an increase in materials going online. usf special collections department rapidly created digital exhibits to showcase their materials. if the trend in remote work continues, there is reason to believe that digital materials may be increasingly present and, given enough time and expertise, libraries can leverage linked data to better support current and new collections. the societal impact of covid-19 worldwide sheds light on the importance of technologies such as linked data that can help increase discoverability. when items are being created and shared online, either directly related to covid-19 or a result of its impact, linked data can help connect those resources. for instance, new covid-19 research is being developed and published daily. the publications office of the european union datathon entry “covid-19 data as linked data” states that “[t]he benefit of having covid-19 data as linked data comes from the ability to link and explore independent sources. for example, covid-19 sources often do not include other regional or mobility data. then, even the simplest thing, having the countries not as a label but as their uri of wikidata and dbpedia, brings rich possibilities for analysis by exploring and correlating geographic, demographic, relief, and mobility data.”36 the more institutions that contribute to this, the greater the discoverability and impact of the data. in 2020 there has been an increase in black lives matter awareness across the country. this affects higher education. usf libraries are not the only ones engaged in addressing racial disparities. many institutions have been doing this for years. others are beginning to focus on this area. no matter whether it’s a new digital collection or one that’s been around for decades, the question remains: how do people find these resources? perhaps linked data technologies can help solve that problem. linked data is a technology that can help accentuate the human effort put forth to create those collections. linked data is a way to assist humans and computers in finding interconnected materials around the internet. usf libraries faced many obstacles implementing linked data. there is a technological barrier that takes well-trained staff to surmount, i.e., creating a linked data triple store database and having linked data interact correctly on webpages. there is a time commitment necessary to create the triples and sparql queries. sparql queries themselves vary from being relatively simple to incredibly complicated. the authors also had the stumbling block of understanding how linked data worked together on a theoretical level. taking all of these considerations into account, we can say that creating linked data for a digital collection is not for the faint of heart. a cost/benefit analysis must be taken and assessed. the authors of this paper must continue to determine the need for linked data. at usf, the authors have taken the first steps in converting digital collections into linked data. we’ve moved from understanding the theoretical basis of linked data and into the practical side where the elements that make up linked data start coming together. the work to create triples, sparql queries, and uris has begun, and full implementation has started. our linked data group has learned the fundamentals of linked data. the next, and current, step is to develop workflows for existing metadata conversion into appropriate linked data. the group meets regularly and has created a triple store database and converted data into linked data. while the process is slow information technology and libraries december 2021 bridging the gap | boczar, pollock, mi, and yeslibas 13 moving due to group members’ other commitments, progress is being made by looking at the most relevant collections we would like to transform and moving forward from there. we’ve located the collections we want to work on, taking an iterative approach to creating linked data as we go. with linked data, there is a lot to consider. how do you start up a linked data program at your institution? how will you get the required expertise to create appropriate and high-quality linked data? how will your institution crosswalk existing data into triples format? is it worth the investment? it may be difficult to answer these questions but they’re questions that must be addressed. the usf libraries will continue pursuing linked data in meaningful ways and showcasing linked data’s importance. linked data can help highlight all collections but more importantly those of marginalized groups, which is a priority of the linked data group. endnotes 1 peter perl, “what is the future of truth?” pew trust magazine,

this case study gives the results a usability study for the discovery tool encore synergy, an innovative interfaces product, launched at appalachian state university belk library & information commons in january 2013. nine of the thirteen participants in the study rated the discovery tool as more user friendly, according to a sus (standard usability scale) score, than the library’s tabbed search layout, which separated the articles and catalog search. all of the study’s participants were in favor of switching the interface to the new “one box” search. several glitches in the implementation were noted and reported to the vendor. the study results have helped develop belk library training materials and curricula. the study will also serve as a benchmark for further usability testing of encore and appalachian state library’s website. this article will be of interest to libraries using encore discovery service, investigating discovery tools, or performing usability studies of other discovery services. introduction appalachian state university’s belk library & information commons is constantly striving to make access to libraries resources seamless and simple for patrons to use. the library’s technology services team has conducted usability studies since 2004 to inform decision making for iterative improvements. the most recent versions (since 2008) of the library’s website have featured a tabbed layout for the main search box. this tabbed layout has gone through several iterations and a move to a new content management system (drupal). during fall semester 2012, the library website’s tabs were: books & media, articles, google scholar, and site search (see figure 1). some issues with this layout, documented in earlier usability studies and through anecdotal experience, will be familiar to other libraries who have tested a tabbed website interface. user access issues include the belief of many patrons that the “articles” tab looked for all articles the library had access to. in reality the “articles” tab searched seven ebsco databases. belk library has access to over 400 databases. another problem noted with the tabbed layout was that patrons often started typing in the articles box, even when they knew they were looking for a book or dvd. this is understandable, since when most of us see a search box we just start typing, we do not read all the information on the page. megan johnson (johnsnm@appstate.edu) is e-learning and outreach librarian, belk library and information commons, appalachian state university, boone, nc. mailto:johnsnm@appstate.edu usability test results for encore in an academic library | johnson 60 figure 1. appalachian state university belk library website tabbed layout search, december 2012. a third documented user issue is confusion over finding an article citation. this is a rather complex problem, since it has been demonstrated through assessment of student learning that many students cannot identify the parts of a citation, so this usability issue goes beyond the patron being able navigate the library’s interface, it is partly a lack of information literacy skills. however, even sophisticated users can have difficulty in determining if the library owns a particular journal article. this is an ongoing interface problem for belk library and many other academic libraries. google scholar (gs) often works well for users with a journal citation, since on campus they can often simply copy and paste a citation to see if the library has access, and, if so, the full text it is often is available in a click or two. however, if there are no results found using gs, the patrons are still not certain if the library owns the item. background in 2010, the library formed a task force to research the emerging market of discovery services. the task force examined summon, ebsco discovery service, primo and encore synergy and found the products, at that time, to still be immature and lacking value. in april 2012, the library reexamined the discovery market and conducted a small benchmarking usability study (the results are discussed in the methodology section and summarized in appendix a). the library felt enough improvements had been made to innovative interface’s encore information technology and libraries | september 2013 61 synergy product to justify purchasing this discovery service. an encore synergy implementation working group was formed, and several subcommittees were created, including end-user preferences, setup & access, training, and marketing. to help inform the decision of these subcommittees, the author conducted a usability study in december 2012, which was based on, and expanded upon, the april 2012 study. the goal of this study was to test users’ experience and satisfaction with the current tabbed layout, in contrast to the “one box” encore interface. the library had committed to implementing encore synergy, but there are options in layout of the search box on the library’s homepage. if users expressed a strong preference for tabs, the library could choose to leave a tabbed layout for access to the articles part of encore, for the catalog part, and create tabs for other options like google scholar, and a search of the library’s website. a second goal of the study was to benchmark the user experience for the implementation of encore synergy so that, over time, improvements could be made to promote seamless access to appalachian state university library’s resources. a third goal of this study was to document problems users encountered and report them to innovative. figure 2. appalachian state university belk library website encore search, january 2013. usability test results for encore in an academic library | johnson 62 literature review there have been several recent reviews of the literature on library discovery services. thomsettscott and reese conclude that discovery tools are a mixed blessing. 1 users can easily search across abroad areas of library resources and limiting by facets is helpful. downsides include loss of individual database specificity and user willingness to look beyond the first page of results. longstanding library interface problems, such as patrons’ lack of understanding of holding statements, and knowing when to it is appropriate to search in a discipline specific database are not solved by discovery tools.2 in a recent overview of discovery services, hunter lists four vendors whose products have both a discovery layer and a central index: ebsco’s discovery service (eds); ex libris’ primo central index; serials solutions’ summon; and oclc’s worldcat local (wcl). 3 encore does not have currently offer a central index or pre-harvested metadata for articles, so although encore has some of the features of a discovery service, such as facets and connections to full text, it is important for libraries considering implementing encore to understand that the part of encore that searches for articles is a federated search. when appalachian purchased encore, not all the librarians and staff involved in the decision making were fully aware of how this would affect the user experience. further discussion of this in the “glitches revealed” section. fagan et al. discuss james madison university’s implementation of ebsco discovery service and their customizations of the tool. they review the literature of discovery tools in several areas, including articles that discuss the selection processes, features, and academic libraries’ decisions process following selection. they conclude, the “literature illustrates a current need for more usability studies related to discovery tools.” 4 the most relevant literature to this study are case studies documenting a library’s experience with implementing a discovery services and task based usability studies of discovery services. thomas and buck5 sought to determine with a task based usability study whether users were as successful performing common catalog-related tasks in worldcat local (wcl) as they are in the library’s current catalog, innovative interfaces’ webpac. the study helped inform the library’s decision, at that time, to not implement wcl. beecher and schmidt6 discuss american university’s comparison of wcl and aquabrowser (two discovery layers), which were implemented locally. the study focused on user preferences based on students “normal searching patterns” 7 rather than completion of a list of tasks. their study revealed undergraduates generally preferred wcl, and upperclassmen and graduates tended to like aquabrower better. beecher and schmidt discuss the research comparing assigned tasks versus user-defined searches, and report that a blend of these techniques can help researchers understand user behavior better.8 information technology and libraries | september 2013 63 this article reports on a task-based study, in which the last question asks the participant to research something they had looked for within the past semester, and the results section indicates that the most meaningful feedback came from watching users research a topic they had a personal interest in. having assigned tasks also can be very useful. for example, an early problem noted with discovery services was poor search results for specific searches on known items, such as the book “the old man and the sea.” assigned tasks also give the user a chance to explore a system for a few searches, so when they search for a topic of personal interest, it is not their first experience with a new system. blending assigned tasks with user tasks proved helpful in this study’s outcomes. encore synergy has not yet been the subject of a formally published task-based usability study. allison reports on an analysis of google analytic statistics at university of nebraska-lincoln after encore was implemented.9 the article concludes that encore increases the user’s exposure to all the library’s holdings, describes some of the challenges unl faced and gives recommendations for future usability studies to evaluate where additional improvements should be made. the article also states unl plans to conduct future usability studies. although there are not yet formal published task-based studies on encore, at least one blogger from southern new hampshire university documented their implementation of the service. singley reported in 2011, “encore synergy does live up to its promise in presenting a familiar, user-friendly search environment.10 she points out, “to perform detailed article searches, users still need to link out to individual databases.” this study confirms that users do not understand that articles are not fully indexed and integrated; articles remain, in encore’s terminology, in “database portfolios.” see the results section, task 2, for a fuller discussion of this topic. method this study included a total of 13 participants. these included four faculty members, and six students recruited through a posting on the library’s website offering participants a bookstore voucher. three student employees were also subjects (these students work in the library’s mailroom and received no special training on the library’s website). for the purposes of this study, the input of undergraduate students, the largest target population of potential novice users, was of most interest. table 3 lists demographic details of the student or faculty’s college, and for students, their year. this was a task-based study, where users were asked to find a known book item and follow two scenarios to find journal articles. the following four questions/tasks were handed to the users on a sheet of paper: 1. find a copy of the book the old man and the sea. 2. in your psychology class, your professor has assigned you a 5-page paper on the topic of eating disorders and teens. find a scholarly article (or peer-reviewed) that explores the relation between anorexia and self-esteem. http://www.snhu.edu/ usability test results for encore in an academic library | johnson 64 3. you are studying modern chinese history and your professor has assigned you a paper on foreign relations. find a journal article that discusses relations between china and the us. 4. what is a topic you have written about this year? search for materials on this topic. the follow up questions where verbally asked either after a task, or asked as prompts while the subject was working. 1. after the first task (find a copy of the book the old man and the sea) when the user finds the book in appsearch, ask: “would you know where to find this book in the library?” 2. how much of the library’s holdings do you think appsearch/ articles quick search is looking across? 3. does “peer reviewed” mean the same as “scholarly article”? 4. what does the “refine by tag” block the right mean to you? 5. if you had to advise the library to either stay with a tabbed layout, or move to the one search box, what would you recommend? participants were recorded using techsmith’s screen-casting software camtasia, which allows the user’s face to be recorded along with their actions on the computer screen. this allows the observer to not rely solely on notes or recall. if the user encounters a problem with the interface, having the session recorded makes it simple to create (or recreate) a clip to show the vendor. in the course of this study, several clips were sent to innovative interfaces, and they were responsive to many of the issues revealed. further discussion is in the “glitches revealed” section. seven of the subjects first used the library site’s tabbed layout (which was then the live site) as seen in figure 1. after they completed the tasks, participants filled in a system usability scale (sus) form. the users then completed the same tasks on the development server using encore synergy. participants next filled out a sus form to reflect their impression of the new interface. encore is locally branded as appsearch and the terms are used interchangeably in this study. the six other subjects started with the appsearch interface on a development server, completed a sus form, and then did the same tasks using the library’s tabbed interface. the time it took to conduct the studies was ranged from fifteen to forty minutes per participant, depending on how verbal the subject was, and how much they wanted to share about their impressions and ideas for improvement. jakob nielson has been quoted as saying you only need to test with five users: “after the fifth user, you are wasting your time by observing the same findings repeatedly but not learning much new.”11 he argues for doing tests with a small number of users, making iterative improvements, and then retesting. this is certainly a valid and ideal approach if you have full control of the design. in the case of a vendor-controlled product, there are serious limitations to what the information technology and libraries | september 2013 65 librarians can iteratively improve. the most librarians can do is suggest changes to the vendor, based on the results of studies and observations. when evaluating discovery services in the spring of 2012, appalachian state libraries conducted a four person task based study (see appendix a), which used university of nebraska at lincoln’s implementation of encore as a test site to benchmark our students’ initial reaction to the product in comparison to the library’s current tabbed layout. in this small study, the average sus score for the library’s current search box layout was 62, and for unl’s implementation of encore, it was 49. this helped inform the decision of belk library, at that time, not to purchase encore (or any other discovery service), since students did not appear to prefer them. this paper reports on a study conducted in december 2012 that showed a marked improvement in users’ gauge of satisfaction with encore. several factors could contribute to the improvement in sus scores. first is the larger sample size of 13 compared to the earlier study with four participants. another factor is in the april study, participants were using an external site they had no familiarity with, and a first experience with a new interface is not a reliable gauge of how someone will come to use the tool over time. this study was also more robust in that it added the task of asking the user to search for something they had researched recently and the follow up questions were more detailed. overall it appears that, in this case, having more than four participants and a more robust design gave a better representation of user experience. the system usability scale (sus) the system usability scale has been widely used in usability studies since its development in 1996. many libraries use this tool in reporting usability results.12,13 it is simple to administer, score, and understand the results.14 sus is an industry standard with references in over 600 publications.15 an “above average” score is 68. scoring a scale involves a formula where odd items have one subtracted from the user response, and with even numbered items, the user response is subtracted from five. the total converted responses are added up, and then multiplied by 2.5. this makes the answers easily grasped on the familiar scale of 1-100. due to the scoring method, it is possible that results are expressed with decimals.16 a sample sus scale is included in appendix d. results the average sus score for the 13 users for encore was 71.5, and for the tabbed layout, the average sus score was 68. this small sample set indicates there was a user preference for the discovery service interface. in a relatively small study like this, these results do not imply a scientifically valid statistical measurement. as used in this study, the sus scores are simply a way to benchmark how “usable” the participants rated the two interfaces. when asked the subjective follow up question, “if you had to advise the library to either stay with a tabbed layout, or move to the one search box, what would you recommend?” 100% of the participants recommended the library change to appsearch, (although four users actually rated usability test results for encore in an academic library | johnson 66 the tabbed layout with a higher sus score). these four participants said things along the lines of, “i can get used to anything you put up.” participant sus sus year and major or

thirteen users had faster success using encore. when using encore, this “known item” is in the top three results. encore definitely performed better than the classic catalog in saving the time of the user. in approaching task 1 from the tabbed layout interface, four out of thirteen users clicked on the books and media tab, changed the drop down search option to “title,” and were (relatively) quickly successful. the remaining nine who switched to the books and media tab and used the default keyword search for “the old man and the sea” had to scan the results (using this search method, the book is the seventh result in the classic catalog), which took two users almost 50 seconds. this length of time, for an “average user” to find a well-known book is not considered to be acceptable to the technology services team at appalachian state university. when using the encore interface, the follow up question for this task was, “would you know where to find this book in the library?” nine out of 13 users did not know where the book would be, or information technology and libraries | september 2013 67 how to find it. the three faculty members and student d could pick out the call number and felt they could locate the book in the stacks. figure 3. detail of the screen of results for searching for “the old man and the sea”. the classic catalog that most participants were familiar with has a “map it” feature (from the third party vendor stackmap), and encore did not have that feature incorporated yet. since this study has been completed, the “map it” has been added to the item record in appsearch. further research can determine if students will have a higher level of confidence in their ability to locate a book in the stacks when using encore. figure 3 shows the search as it appeared in december 2012 and figure 4 has the “map it” feature implemented and pointed out with a red arrow. related to this task of searching for a known book, student b commented that in encore, the icons were very helpful in picking out media type. figure 4. book item record in encore. the red arrow indicates the “map it” feature, an add-on to the catalog from the vendor stackmap. browse results are on the right, and only pull from the catalog results. when using the tabbed layout interface (see figure 1), three students typed the title of the book into the “articles” tab first, and it took them a few moments figure out why they had a problem with the results. they were able to figure it out and re-do the search in the “correct” books & usability test results for encore in an academic library | johnson 68 media tab, but student d commented, “i do that every time!” this is evidence that the average user does not closely examine a search box--they simply start typing. task 2: “in your psychology class, your professor has assigned you a five-page paper on the topic of eating disorders and teens. find a scholarly article (or peer-reviewed) that explores the relation between anorexia and self-esteem.” this question revealed, among other things, that seven out of the nine students did not fully understand the term scholarly or peer reviewed article are meant to be synonyms in this context. when asked the follow up question “what does ‘peer reviewed’ mean to you?” student b said, “my peers would have rated it as good on the topic.” this is the kind of feedback that librarians and vendors need to be aware of in meeting students’ expectations. users have become accustom to online ratings by their peers of hotels and restaurants, so the terminology academia uses may need to shift. further discussion on this is in the “changes suggested” section below. figure 5. typical results for task two. figure 5 shows a typical user result for task 2. the follow up question asked users “what does the refine by tag box on the right mean to you?” student g reported they looked like internet ads. other users replied with variations of, “you can click on them to get more articles and stuff.” in fact, the “refine by tag” box in the upper right column top of screen contains only indexed terms from the subject heading of the catalog. this refines the current search results to those with the specific subject term the user clicked on. in this study, no user clicked on these tags. information technology and libraries | september 2013 69 for libraries considering purchasing and implementing encore, a choice of skins is available, and it is possible to choose a skin where these boxes do not appear. in addition to information from innovative interfaces, libraries can check a guide maintained by a librarian at saginaw valley state university17 to see examples of encore synergy sites, and links to how different skins (cobalt, pearl or citrus) affect appearance. appalachian uses the “pearl” skin. figure 6. detail of screenshot in figure 5. figure 6 is a detail of the results shown in the screenshot for average search for task 2. the red arrows

screen. figure 7 shows the encore’s advanced search screen. this search is not designed to search articles; it only searches the catalog. this aspect of advanced search was not clear to any of the participants in this study. see further discussion of this issue in the “glitches revealed” section. information technology and libraries | september 2013 71 figure 8. the "database portfolio" for arts & humanities. figure 8 shows typical results for task 2 limited just to articles. the folders on the left are basically silos of grouped databases. innovative calls this feature “database portfolios.” in this screen shot, the results of the search narrowed to articles within the “database portfolio” of arts & humanities. clicking on the individual databases return results from that database, and moves the usability test results for encore in an academic library | johnson 72 user to the database’s native interface. for example, in figure 8, clicking on art full text would put the user into that database, and retrieve 13 results. while conducting task 2, faculty member a stressed she felt it was very important students learn to use discipline specific databases, and stated she would not teach a “one box” approach. she felt the tabbed layout was much easier than appsearch and rated the tabbed layout in her sus score with a 87.5 versus the 40 she gave encore. she also wrote on the sus scoring sheet “appsearch is very slow. there is too much to review.” she also said that the small niche showing how to switch results between “books & more” to article was “far too subtle.” she recommended bold tabs, or colors. this kind of suggestion librarians can forward to the vendor, but we cannot locally tweak this layout on a development server to test if it improves the user experience. figure 9. closeup of switch for “books & more” and “articles” options. task 3: “you are studying modern chinese history and your professor has assigned you a paper on foreign relations. find a journal article that discusses relations between china and the us.” most users did not have much difficulty finding an article using encore, though three users did not immediately see a way to limit only to articles. of the nine users who did narrow the results to articles, five used facets to further narrow results. no users moved beyond the first page of results. search strategy was also interesting. all thirteen users appeared to expect the search box to work like google. if there were no results, most users went to the advanced search, and reused the same terms on different lines of the boolean search box. once again, no users intuitively understood that “advanced search” would not effectively search for articles. the concept of changing search terms was not a common strategy in this test group. if very few results came up, none of the users clicked on the “did you mean” or used suggestions for correction in spelling or change in terms supplied by encore. during this task, two faculty members commented on load time. they said students would not wait, results had to be instant. but when working with students, when the author asked how they felt when load time was slow, students almost all said it was fine, or not a problem. they could “see it was working.” one student said, “oh, i’d just flip over to facebook and let the search run.” so perhaps librarians should not assume we fully understand student user expectations. it is also information technology and libraries | september 2013 73 worth noting that, for the participant, this is a low-stakes usability study, not crunch time, so attitudes may be different if load time is slow for an assignment due in a few hours. task 4: “what is a topic you have written about this year? search for materials on this topic.” this question elicited the most helpful user feedback, since participants had recently conducted research using the library’s interface and could compare ease of use on a subject they were familiar with. a few specific examples follow. student a, in response to the task to research something she had written about this semester, looked for “elder abuse.” she was a senior who had taken a research methods class and written a major paper on this topic, and she used the tabbed layout first. she was familiar with using the facets in ebsco to narrow by date, and to limit to scholarly articles. when she was using appsearch on the topic of elder abuse, encore held her facets “full text” and “peer reviewed” from the previous search on china and u.s. foreign relations. an example of encore “holding a search” is demonstrated in figures 10 and 11 below. student a was not bothered by the encore holding limits she had put on a previous search. she noticed the limits, and then went on to further narrow within the database portfolio of “health” which limited the results to the database cinahl first. she was happy with being able to limit by folder to her discipline. she said the folders would help her sort through the results. student g’s topic she had researched within the last semester was “occupational therapy for students with disabilities” such as cerebral palsy. she understood through experience, that it would be easiest to narrow results by searching for ‘occupational therapy’ and then add a specific disability. student g was the user who made the most use of facets on the left. she liked encore’s use of icons for different types of materials. student b also commented on “how easy the icons made it.” faculty b, in looking for the a topic he had been researching recently in appsearch, typed in “writing across the curriculum glossary of terms” and got no results on this search. he said, “mmm, well that wasn’t helpful, so to me, that means i’d go through here” and he clicked on the google search box in the browser bar. he next tried removing “glossary of terms” from his search and the load time was slow on articles, so he gave up after ten seconds and clicked on “advanced search” and tried putting “glossary of terms” in the second line. this led to another dead end. he said, “i’m just surprised appalachian doesn’t have anything on it.” the author asked if he had any other ideas about how to approach finding materials on his topic from the library’s homepage and he said no, he would just try google (in other words, navigating to the group of databases for education was not a strategy that occurred to him). usability test results for encore in an academic library | johnson 74 the faculty member d had been doing research on a relatively obscure historical event and was able to find results using encore. when asked if he had seen the articles before, he said, “yes, i’ve found these, but it is great it’s all in one search!” glitches revealed it is of concern for the user experience that the advanced search of encore does not search articles; it only searches the catalog. this was not clear to any participant in this study. as noted earlier, encore’s article search is a federated search. this affects load time for article results, and also puts the article results into silos, or to use encore’s terminology, “database portfolios.” encore’s information on their website definitely markets the site as a discovery tool, saying, it “integrates federated search, as well as enriched content—like first chapters—and harvested data… encore also blends discovery with the social web. 18” it is important for libraries considering purchase of encore that while it does have many features of a discovery service, it does not currently have a central index with pre-harvested metadata for articles. if innovative interfaces is going to continue to offer an advanced search box, it needs to be made explicitly clear that the advanced search is not effective for searching for articles, or innovative interfaces needs to make an advanced search work with articles by creating a central index. to cite a specific example from this study, when student e was using appsearch, with all the tasks, after she ran a search, she clicked on the advanced search option. the author asked her, “so if there is an advanced search, you’re going to use it?” the student replied, “yeah, they are more accurate.” another aspect of encore that users do not intuitively grasp is that when looking at the results for an article search, the first page of results comes from a quick search of a limited number of databases (see figure 8). the users in this study did understand that clicking on the folders will narrow by discipline, but they did not appear to grasp that the result in the database portfolios are not included in the first results shown. when users click on an article result, they are taken to the native interface (such as psych info) to view the article. users seemed un-phased when they went into a new interface, but it is doubtful they understand they are entering a subset of appsearch. if users try to add terms or do a new search in the native database they may get relevant results, or may totally strike out, depending on chosen database’s relevance to their research interest. information technology and libraries | september 2013 75 figure 10. changing a search in encore. another problem that was documented was that after users ran a search, if they changed the text in the “search” box, the results for articles did not change. figure six demonstrates the results from task 2 of this study, which asks users to find information on anorexia and self-esteem. the third task asks the user to find information on china and foreign relations. figure 10 demonstrates the results for the anorexia search, with the term “china” in the search box, just before the user clicks enter, or the orange arrow for new search. figure 11. search results for changed search. figure 11 show that the search for the new term, “china” has worked in the catalog, but the results for articles are still about anorexia. in this implementation of encore, there is no “new search button” (except in the advanced search page, there is a “reset search” button, see figure 7) and usability test results for encore in an academic library | johnson 76 refreshing the browser is had no effect on this problem. this issue was screencast19 and sent to the vendor. happily, as of april 2013, innovative interfaces appears to have resolved this underlying problem. one purpose of this study was to determine if users had a strong preference for tabs, since the library could choose to implement encore with tabs (one for access to articles, one for the catalog, and other tab options like google scholar). this study indicated users did not like tabs in general, they much preferred a “one box solution” on first encounter. a major concern raised was the user’s response to the question, “how much of the library’s holdings do you think appsearch/ articles quick search is looking across?” twelve out of thirteen users believed that when they were searching for articles from the quick search for articles tabbed layout, they were searching all the library databases. the one exception to this was a faculty member in the english department, who understood that the articles tab searched a small subset of the available resources (seven ebsco databases out of 400 databases the library subscribes to). all thirteen users believed appsearch (encore) was searching “everything the library owned.” the discovery service searches far more resources than other federated searches the library has had access to in the past, but it is still only searching 50 out of 400 databases. it is interesting that in the fagan et al. study of ebsco’s discovery service, only one out of ten users in that study believed the quick search would search “all” the library’s resources.20 a glance at james madison university’s library homepage21 suggests wording that may improve user confusion. figure 12. screenshot of james madison library homepage, accessed december 18, 2012. information technology and libraries | september 2013 77 figure 13. original encore interface as implemented in january 2013. given the results that 100% of the users believed that appsearch looked at all databases the library has access to, the library made changes to the wording in the search box. (see figure 7). future tests can determine if this has any positive effect on the understanding of what appsearch includes. figure 14. encore search box after this usability study was completed. the arrow highlights additions to the page as a result of this study. some other wording changes suggested were from the finding that only seven out of nine students fully understood that “peer reviewed” would limit to scholarly articles. a suggestion was made to innovative interfaces to change the wording to “scholarly (peer reviewed)” and they did so in early january. although innovative’s response on this issue was swift, and may help students, changing the wording does not address the underlying information literacy issue of what students understand about these terms. interestingly, encore does not include any “help” pages. appalachian’s liaison with encore has asked about this and been told by encore tech support that innovative feels the product is so intuitive; users will not need any help. belk library has developed a short video tutorial for users, and local help pages are available from the library’s homepage, but according to innovative, a link to these resources cannot be added to the top right area of the encore screen (where help is commonly located in web interfaces). although it is acknowledged that few users actually read “help” pages, it seems like a leap of faith to think a motivated searcher will understand things like the “database portfolios” (see figures 9) without any instruction at all. after implementation, the usability test results for encore in an academic library | johnson 78 librarians here at appalachian conducted internally developed training for instructors teaching appsearch, and all agreed that understanding what is being searched and how to best perform a task such as an advanced article search is not “totally intuitive,” even for librarians. finally, some interesting search strategy patterns were revealed. on the second and third questions in the script (both having to do with finding articles) five of the thirteen participants had the strategy of putting in one term, then after the search ran, adding terms to narrow results using the advanced search box. although this is a small sample set, it was a common enough search strategy to make the author believe this is not an unusual approach. it is important for librarians and for vendors to understand how users approach search interfaces so we can meet expectations. further research the findings of this study suggest librarians will need to continue to work with vendors to improve discovery interfaces to meet users expectations. the context of what is being searched and when is not clear to beginning users in encore one aspect of this test was it was the participants’ first encounter with a new interface, and even student d, who was unenthused about the new interface (she called the results page “messy, and her sus score was 37.5 for encore, versus 92 for the tabbed layout) said that she could learn to use the system given time. further usability tests can include users who have had time to explore the new system. specific tasks that will be of interest in follow up studies of this report are if students have better luck in being able to know where to find the item in the stacks with the addition of the “map it” feature. locally, librarian perception is that part of the problem with this results display is simply visual spacing. the call number is not set apart or spaced so that it stands out as important information (see figure 5 for a screenshot). another question to follow up on will be to repeat the question, “how much of the library’s holdings do you think appsearch is looking across?” all thirteen users in this study believed appsearch was searching “everything the library owned.” based on this finding, the library made small adjustments to the initial search box (see figures 14 and 15 as illustration). it will be of interest to measure if this tweak has any impact. summary all users in this study recommended that the library move to encore’s “one box” discovery service instead of using a tabbed layout. helping users figure out when they should move to using discipline specific databases will most likely be a long-term challenge for belk library, and for other academic libraries using discovery services, but this will probably trouble librarians more than our users. information technology and libraries | september 2013 79 the most important change innovative interfaces could make to their discovery service is to create a central index for articles, which would improve load time and allow for an advanced search feature for articles to work efficiently. because of this study, innovative interfaces made a wording change in search results for article to include the word “scholarly” when describing peer reviewed journal articles in belk library’s local implementation. appalachian state university libraries will continue to conduct usability studies and tailor instruction and e-learning resources to help users navigate encore and other library resources. overall, it is expected users, especially freshman and sophomores, will like the new interface but will not be able to figure out how to improve search results, particularly for articles. belk library & information commons’ instruction team is working on help pages and tutorials, and will incorporate the use of encore into the library’s curricula. references 1 . thomsett-scott, beth, and patricia e. reese.

(note: half the participants to start at the development site, the other half start at current site). after each set of tasks is finished, you will fill out a standard usability scale to rate your experience. this session should take about twenty minutes. the first thing i want to make clear is that we're testing the interface, not you. you can't do anything wrong here. do you have any questions so far? ok. before we look at the site, i'd like to ask you just a few quick questions. what year are you in college? what are you majoring in? roughly how many hours a week altogether--just a ballpark estimate--would you say you spend using the library website? ok, great. hand the user the task sheet. do not read the instructions to the participant, allow them to read the directions for themselves. allow the user to proceed until they hit a wall or become frustrated. verbally encourage them to talk aloud about their experience. usability test results for encore in an academic library | johnson 83 written instructions for participants. find the a copy of the book the old man and the sea. in your psychology class, your professor has assigned you a 5-page paper on the topic of eating disorders and teens. find a scholarly article (or peer-reviewed) that explores the relation between anorexia and self-esteem. you are studying modern chinese history and your professor has assigned you a paper on foreign relations. find a journal article that discusses relations between china and the us. what is a topic you have written about this year? search for materials on this topic. usability test results for encore in an academic library | johnson 84 appendix c follow up questions for participants (or ask as the subject is working) after the first task (find a copy of the book the old man and the sea) when the user finds the book in appsearch, ask “would you know where to find this book in the library?” how much of the library’s holdings do you think appsearch/ articles quick search is looking across? does “peer reviewed” mean the same as “scholarly article”? what does the “refine by tag” block the right mean to you? if you had to advise the library to either stay with a tabbed layout, or move to the one search box, what would you recommend? do you have any questions for me, now that we're done? thank subject for participating. usability test results for encore

comments: 16 information technology and libraries | march 2009 mathew j. miles and scott j. bergstrom classification of library resources by subject on the library website: is there an optimal number of subject labels? the number of labels used to organize resources by subject varies greatly among library websites. some librarians choose very short lists of labels while others choose much longer lists. we conducted a study with 120 students and staff to try to answer the following question: what is the effect of the number of labels in a list on response time to research questions? what we found is that response time increases gradually as the number of the items in the list grow until the list size reaches approximately fifty items. at that point, response time increases significantly. no association between response time and relevance was found. i t is clear that academic librarians face a daunting task drawing users to their library’s web presence. “nearly three-quarters (73%) of college students say they use the internet more than the library, while only 9% said they use the library more than the internet for information searching.”1 improving the usability of the library websites therefore should be a primary concern for librarians. one feature common to most library websites is a list of resources organized by subject. libraries seem to use similar subject labels in their categorization of resources. however, the number of subject labels varies greatly. some use as few as five subject labels while others use more than one hundred. in this study we address the following question: what is the effect of the number of subject labels in a list on response times to research questions? n literature review mcgillis and toms conducted a performance test in which users were asked to find a database by navigating through a library website. they found that participants “had difficulties in choosing from the categories on the home page and, subsequently, in figuring out which database to select.”2 a review of relevant research literature yielded a number of theses and dissertations in which the authors compared the usability of different library websites. jeng in particular analyzed a great deal of the usability testing published concerning the digital library. the following are some of the points she summarized that were highly relevant to our study: n user “lostness”: users did not understand the structure of the digital library. n ambiguity of terminology: problems with wording accounted for 36 percent of usability problems. n finding periodical articles and subject-specific databases was a challenge for users.3 a significant body of research not specific to libraries provides a useful context for the present research. miller’s landmark study regarding the capacity of human shortterm memory showed as a rule that the span of immediate memory is about 7 ± 2 items.4 sometimes this finding is misapplied to suggest that menus with more than nine subject labels should never be used on a webpage. subsequent research has shown that “chunking,” which is the process of organizing items into “a collection of elements having strong associations with one another, but weak associations with elements within other chunks,”5 allows human short-term memory to handle a far larger set of items at a time. larson and czerwinski provide important insights into menuing structures. for example, increasing the depth (the number of levels) of a menu harms search performance on the web. they also state that “as you increase breadth and/or depth, reaction time, error rates, and perceived complexity will all increase.”6 however, they concluded that a “medium condition of breadth and depth outperformed the broadest, shallow web structure overall.”7 this finding is somewhat contrary to a previous study by snowberry, parkinson, and sisson, who found that when testing structures of 26, 43, 82, 641 (26 means two menu items per level, six levels deep), the 641 structure grouped into categories proved to be advantageous in both speed and accuracy.8 larson and czerwinksi recommended that “as a general principle, the depth of a tree structure should be minimized by providing broad menus of up to eight or nine items each.”9 zaphiris also corroborated that previous research concerning depth and breadth of the tree structure was true for the web. the deeper the tree structure, the slower the user performance.10 he also found that response times for expandable menus are on average 50 percent longer than sequential menus.11 both the research and current practices are clear concerning the efficacy of hierarchical menu structures. thus it was not a focus of our research. the focus instead was on a single-level menu and how the number and characteristics of subject labels would affect search response times. n background in preparation for this study, library subject lists were collected from a set of thirty library websites in the united mathew j. miles (milesm@byui.edu) is systems librarian and scott j. bergstrom (bergstroms@byui.edu) is director of institutional research at brigham young university–idaho in rexburg. classification of library resources by subject on the library website | miles and bergstrom 17 states, canada, and the united kingdom. we selected twelve lists from these websites that were representative of the entire group and that varied in size from small to large. to render some of these lists more usable, we made slight modifications. there were many similarities between label names. n research design participants were randomly assigned to one of twelve experimental groups. each experimental group would be shown one of the twelve lists that were selected for use in this study. roughly 90 percent of the participants were students. the remaining 10 percent of the participants were full-time employees who worked in these same departments. the twelve lists ranged in number of labels from five to seventy-two: n group a: 5 subject labels n group b: 9 subject labels n group c: 9 subject labels n group d: 23 subject labels n group e : 6 subject labels n group f: 7 subject labels n group g: 12 subject labels n group h: 9 subject labels n group i: 35 subject labels n group j: 28 subject labels n group k: 49 subject labels n group l: 72 subject labels each participant was asked to select a subject label from a list in response to eleven different research questions. the questions are listed below: 1. which category would most likely have information about modern graphical design? 2. which category would most likely have information about the aztec empire of ancient mexico? 3. which category would most likely have information about the effects of standardized testing on high school classroom teaching? 4. which category would most likely have information on skateboarding? 5. which category would most likely have information on repetitive stress injuries? 6. which category would most likely have information about the french revolution? 7. which category would most likely have information concerning walmart’s marketing strategy? 8. which category would most likely have information on the reintroduction of wolves into yellowstone park? 9. which category would most likely have information about the effects of increased use of nuclear power on the price of natural gas? 10. which category would most likely have information on the electoral college? 11. which category would most likely have information on the philosopher emmanuel kant? the questions were designed to represent a variety of subject areas that library patrons might pursue. each subject list was printed on a white sheet of paper in alphabetical order in a single column, or double columns when needed. we did not attempt to test the subject lists in the context of any web design. we were more interested in observing the effect of the number of labels in a list on response time independent of any web design. each participant was asked the same eleven questions in the same order. the order of questions was fixed because we were not interested in testing for the effect of order and wanted a uniform treatment, thereby not introducing extraneous variance into the results. for each question, the participant was asked to select a label from the subject list under which they would expect to find a resource that would best provide information to answer the question. participants were also instructed to select only a single label, even if they could think of more than one label as a possible answer. participants were encouraged to ask for clarification if they did not fully understand the question being asked. recording of response times did not begin until clarification of the question had been given. response times were recorded unbeknownst to the participant. if the participant was simply unable to make a selection, that was also recorded. two people administered the exercise. one recorded response times; the other asked the questions and recorded label selections. relevance rankings were calculated for each possible combination of labels within a subject list for each question. for example, if a subject list consisted of five labels, for each question there were five possible answers. two library professionals—one with humanities expertise, the other with sciences expertise—assigned a relevance ranking to every possible combination of question and labels within a subject list. the rankings were then averaged for each question–label combination. n results the analysis of the data was undertaken to determine whether the average response times of participants, adjusted by the different levels of relevance in the subject list labels that prevailed for a given question, were significantly different across the different lists. in other words, would the response times of participants using a particular list, for whom the labels in the list were highly relevant 18 information technology and libraries | march 2009 to the question, be different from students using the other lists for whom the labels in the list were also highly relevant to the question? a separate univariate general linear model analysis was conducted for each of the eleven questions. the analyses were conducted separately because each question represented a unique search domain. the univariate general linear model provided a technique for testing whether the average response times associated with the different lists were significantly different from each other. this technique also allowed for the inclusion of a covariate—relevance of the subject list labels to the question—to determine whether response times at an equivalent level of relevance was different across lists. in the analysis model, the dependent variable was response time, defined as the time needed to select a subject list label. the covariate was relevance, defined as the perceived match between a label and the question. for example, a label of “economics” would be assessed as highly relevant to the question, what is the current unemployment rate? the same label would be assessed as not relevant for the question, what are the names of four moons of saturn? the main factor in the model was the actual list being presented to the participant. there were twelve lists used in this study. the statistical model can be summarized as follows: response time = list + relevance + (list × relevance) + error the general linear model required that the following conditions be met: first, data must come from a random sample from a normal population. second, all variances with each of the groupings are the same (i.e., they have homoscedasticity). an examination of whether these assumptions were met revealed problems both with normality and with homoscedasticity. a common technique— logarithmic transformation—was employed to resolve these problems. accordingly, response-time data were all converted to common logarithms. an examination of assumptions with the transformed data showed that all questions but three met the required conditions. the three 0.70 0.80 0.90 1.00 1.10 1.20 0.50 0.60 avg log performance trend figure 1. the overall average of average search times for the eight questions for all experimental groups (i.e., lists) questions (5, 6, and 7) were excluded from subsequent analysis. n conclusions the series of graphs in the appendix show the average response times, adjusted for relevance, for eight of the eleven questions for all twelve lists (i.e., experimental groups). three of the eleven questions were excluded from the analysis because of heteroscedascity. an inspection of these graphs shows no consistent pattern in response time as the number of the items in the lists increase. essentially, this means that, for any given level of relevance, the number of items of the list does not affect response time significantly. it seems that for a single question, characteristics of the categories themselves are more important than the quantity of categories in the list. the response times using a subject list with twenty-eight labels is similar to the response times using a list of six labels. a statistical comparison of the mean response time for each classification of library resources by subject on the library website | miles and bergstrom 19 group with that of each of the other groups for each of the questions largely confirms this. there were very few statistically significant different comparisons. the spikes and valleys of the graphs in the appendix are generally not significantly different. however, when the average response time associated with all lists is combined into an overall average from all eight questions, a somewhat clearer picture emerges (see figure 1). response times increase gradually as the number of the items in the list increase until the list size reaches approximately fifty items. at that point, response time increases significantly. no association was found between response time and relevance. a fast response time did not necessarily yield a relevant response, nor did a slow response time yield an irrelevant response. n observations we observed that there were two basic patterns exhibited when participants made selections. the first pattern was the quick selection—participants easily made a selection after performing an initial scan of the available labels. nevertheless, a quick selection did not always mean a relevant selection. the second pattern was the delayed selection. if participants were unable to make a selection after the initial scan of items, they would hesitate as they struggled to determine how the question might be reclassified to make one of the labels fit. we did not have access to a high-tech lab, so we were unable to track eye movement, but it appeared that the participants began scanning up and down the list of available items in an attempt to make a selection. the delayed selection seemed to be a combination of two problems: first, none of the available labels seemed to fit. second, the delay in scanning increased as the list grew larger. it’s possible that once the list becomes large enough, scanning begins to slow the selection process. a delayed selection did not necessarily yield an irrelevant selection. the label names themselves did not seem to be a significant factor affecting user performance. we did test three lists, each with nine items and each having different labels, and response times were similar for the three lists. a future study might compare a more extensive number of lists with the same number of items with different labels to see if label names have an effect on response time. this is a particular challenge to librarians in classifying the digital library, since they must come up with a few labels to classify all possible subjects. creating eleven questions to span a broad range of subjects is also a possible weakness of the study. we had to throw out three questions that violated the assumptions of the statistical model. we tried our best to select questions that would represent the broad subject areas of science, arts, and general interest. we also attempted to vary the difficulty of the questions. a different set of questions may yield different results. references 1. steve jones, the internet goes to college, ed. mary madden (washington, d.c.: pew internet and american life project, 2002): 3,

center institutional repositories. yet adoption rates among potential repository users are hampered by a number of factors, prominent among which are difficulties with basic usability. in their efforts to implement a local instance of inveniordm, a turnkey next generation repository, team members at northwestern university’s galter health sciences library & learning center supplemented agile development principles and methods and a user experience design-centered approach with observations of users’ microinteractions (interactions with each part of the software’s interface that requires human intervention). microinteractions were observed through user testing sessions conducted in fall 2019. the result has been a more user-informed development effort incorporating the experiences and viewpoints of a multidisciplinary team of researchers spanning multiple departments of a highly ranked research university. introduction galter health sciences library & learning center facilitates and supports the discoverability of knowledge for the faculty, students, and staff of the feinberg school of medicine at northwestern university. as an integrated unit in northwestern university’s clinical and translational sciences institute (nucats) and a key partner to other institutes across northwestern university’s two campuses, enabling maximum ease of use of library resources and support for meaningful information discoveries for researchers at all stages has been a prime motivator. these motivators helped drive the selection and development of an upgraded institutional repository infrastructure at galter, a project which began in 2018. discovery of resources through repository tools depends upon many factors: metadata and controlled vocabularies used, storage and retrieval capacity, and familiarity and comfort level with mailto:sara.gonzales2@northwestern.edu mailto:matthew.carson@northwestern.edu mailto:guillaume.viger@northwestern.edu

testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 2 the tool on the part of researchers and students. is the institutional repository link easy to find on the website? more importantly, is it easy to use? can records be created and files uploaded with ease? do searches bring meaningful results, and can they be filtered and organized for maximum impact? from early on in the repository upgrade project, galter library partnered with northwestern’s institute for innovations in developmental sciences (devsci), both to answer these questions and to find practical ways to serve researchers who aimed to discover relevant datasets through a repository. the work of the interdisciplinary devsci group is focused on human development across the lifespan in all areas, including physical, emotional, psychological, and socioeconomic, providing a multidisciplinary perspective for the collaboration. through this partnership, devsci’s goal was to develop a data repository or index through which they could discover the datasets of their fellow researchers and find new collaborators, thus providing an ideal perspective from which to provide critical feedback. galter health sciences library & learning center selected the inveniordm (research data management) extensible institutional repository (ir) platform as its local ir code upgrade. inveniordm is a python-based, modular and scalable ir developed by cern (the european organization for nuclear research) and collaborators.1 the first version of the invenio framework was developed in 2000. in 2018, invenio 3.02 was released with significantly improved software and code rewritten to make it a modular framework. this new framework now serves as a foundation for modern research data management and scholarly communications through a trusted digital repository. inveniordm is being collaboratively developed, with its many partners and robust developer community ensuring the framework’s maintenance, improvement, and preservation capacity into the foreseeable future. to galter library and its partners at devsci, the development timespan required to build a local instance of inveniordm presented the perfect opportunity to address one of the major stumbling blocks of ir adoption: the user experience. if a repository were designed with users’ needs in mind, and took into account their behaviors and interactions with every aspect of the tool, it had the potential to increase adoption and usability far beyond numbers generally observed for university irs. designing for user behaviors was the goal of galter library’s repository development team as we launched a round of user testing of the repository’s alph a version in fall 2019. literature review it is an exciting time for irs serving researchers in the sciences and particularly in the field of biomedical research. new robust repository frameworks capable of storing and preserving data for decades into the future are being developed to meet widely articulated researcher needs, including those user behaviors and technologies highlighted by the confederation of open access repositories (coar) in detailed guidelines for next generation repository features.3 these features include interoperable resource transfer, metadata-enhanced discovery by navigation, and exposure of permanent identifiers. researcher-focused organizations such as coar endorse and promulgate fair principles to make deposited and shared data findable, accessible, interoperable, and reusable.4 meanwhile, federal agencies such as the national institutes of health are increasingly incorporating policies to encourage best practices for data management and data sharing of grant funded research.5 these policies often recommend depositing data in a robust, secure, and accessible ir which can be maintained by the researchers’ own institution. in recent years, the majority of the deposited products of research have been stored in subject repositories information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 3 or made available via social media platforms which carry no guarantee of long-term curation and preservation of shared resources. this happens even though institutional repositories are wellrepresented on the overall repository landscape, suggesting that these institutional assets are underutilized in critical data workflows.6 the reasons for slow adoption and use of institutional repositories (ir) by researchers in routine workflows are many: irs can be perceived as adding to researchers’ administrative work burden through the need to clean, deposit, and catalog data and other research outputs; many feel trepidation about open science practices and their effects on citation counts; and researchers may feel unsure about copyright restrictions on materials they might deposit.7 narayan and luca, in their study of one university’s ir adoption challenges, outline some of the deep-seated motivations behind this trepidation, such as the social and psychological barriers imposed by researchers’ own, and university-encouraged, traditional views of scholarly publishing, as well as the ways in which these views are heavily supported by university systems in their tenure and promotion policies. in addition, many researchers perceive the content contained in irs as restricted or of limited use compared to the volume of resources that can be found through a google search.8 the ir is often seen as a small island within the larger digital research landscape. the degree to which repository managers are attuned to their local users’ professional and personal needs with regard to a repository will have a large impact on adoption rates among hesitant user populations. as witt and betz & hall point out, professional motivators have arisen in multiple disciplines to deposit in irs not only preprints, but datasets, data dictionaries, readme files, and other reproducibility-supporting resources, in order to provide open access to the products of federally funded research.9 building on funder and publisher mandates for making both publications and datasets open access, ir builders and maintainers can employ various methods to increase the motivation momentum towards ir adoption. they can highlight repository champions, faculty users of ir tools who can provide use cases and success stories about the benefits the ir brings to them, as both depositors and searchers.10 they can help to allay fears and confusion around depositors’ rights with regard to deposited materials by carefully explicating license types and definitions and by consulting with researchers on the correct licenses to choose for their deposits. they can work with their repository’s developers to create value-added modifications to the repository, including user-friendly browsing, featured collections, and researcher pages, which highlight the most current research at the institution.11 importantly, if the ir maintainers are able to modify the repository’s interface to suit local needs, they can help ensure that the majority of users have a positive experience with the repository’s interface, one in which every interaction is intuitive and in which there are no wasted steps or unnecessary clutter. such usability can be achieved through examining repository users’ microinteractions, that is, interactions with each small part of the software’s interface that requires human intervention. for those engaged in library technology projects in recent years, user experience (ux) design will be a familiar concept. ux design seeks to make a user’s interaction with a product—often a webbased tool—easier and more intuitive, frequently through manipulating the behavior of the user.12 however, in the recent trend toward designing with a focus on microinteractions, software developers are influenced by the data they glean from observing users’ interactions with each part of the software’s interface that requires human intervention, noting from the users themselves the intuitive and non-intuitive parts of an interaction in order to determine where changes should be made.13 the development team for inveniordm has taken an approach that combines traditional information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 4 user-experience design based around collaborative, open source code and tools and common dataset metadata standards such as datacite (https://schema.datacite.org); observations from invenio’s 20 years of serving as cern’s ir; and examination of microinteractions at certain key stages of development. these microinteractions revolve around common user actions within an ir, including depositing items, searching, browsing, and creating a user account.14 the result of combining these approaches has allowed galter health sciences library & learning center to put users’ needs at the forefront of its new ir. inveniordm: a next-generation repository galter library’s selection of a new ir solution was carefully considered and motivated by the organization’s need for a robust, forward-looking, and feature-rich repository that could support best practices in research data management and sharing as realized through the invenio framework. the python framework incorporates community-built python libraries, while also leveraging flask, a postgresql or mysql back-end database, the react js user interface, and the extremely fast elasticsearch json-native distributed search engine. the resulting tool is eminently scalable, securely housing petabytes’ worth of easily discoverable records. galter library began our collaboration with cern to build a local instance of inveniordm, while contributing to the overall repository source code, in late 2018. since that time, a local developer has worked on the code and contributed to the repository’s project roadmap, updating github issues and pushing releases.15 a project manager, data librarian, and the library leadership have also been involved throughout the project in the areas of general guidance and management, oversight, assessment, dissemination and outreach, and requirements gathering. many requirements were gleaned from the devsci community through conversations and informal interviews around data storage practices. in early 2019, to ensure that the repository was meeting the initially envisioned requirements, the galter library repository team analyzed the requirements thus far gathered for the project, which had been translated into github issues and added to by team members and collaborators. the requirements gathered from devsci collaborators and galter librarians were found to map directly into key ir functional categories outlined separately by ir stakeholders throughout the globe such as the national institutes of health, the confederation of open access repositories, the digital repository of ireland, the department of computer and information sciences at covenant university, nigeria, and others. those requirements included record creation and ingest, robust metadata for accessing a record, user account and permissions, user authentication, search functionality, resource access/download, and community pages and features (see fig. 1).16 https://schema.datacite.org/ information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 5 figure 1. local repository requirements mapped to ir functional categories. with the repository’s key functional requirements defined, the development team needed realworld data to help inform the microinteractions that would bring the functions to life, both for repository managers and users. to acquire microinteraction data, galter library’s data librarian designed and organized a round of user testing of the alpha release of the repository in autumn 2019. the alpha release of inveniordm was completed by september 2019, meeting a deadline established by one of the project’s key funders, the national center for data to health (cd2h), information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 6 through a grant funded by the national center for advancing translational sciences (ncats). this early alpha release enabled record creation and file upload, application of seven metadata elements (title, authors, description, resource type, subjects, visibility, and license), user authentication, search, faceting/filtering, and download of resources. to make the experience of searching the alpha release repository as realistic as possible, the data librarian asked colleagues from devsci to provide data for seed records for the repository, based on their own research. colleagues willingly obliged, and over a dozen seed records based on realworld clinical studies and other studies focused on human development were created in early october 2019. while conducting email and word-of-mouth recruitment with members of the devsci community, the data librarian worked on a testing script designed to require the maximum amount of microinteractions possible as each user worked with the repository. the script asked users to complete the following list of tasks (see fig. 2), while thinking aloud and noting anything that they found unusual or anything that they would have expected to see in the user interface of the repository. figure 2. ir user testing script tasks. the user testing tasks conform to many of the functional requirements for institutional repositories identified from our requirements gathering (fig. 1), including user authentication and account, search functionality, resource access/download, record creation/ingest, and robust metadata for accessing a record (detailed record page). by october 2019, ten northwestern university faculty members, mainly from devsci, and two information professionals had agreed to test the alpha version of inveniordm. the data librarian arranged to securely host testing sessions through web conferencing software. testers agreed to have the sessions recorded and shared their screens as they worked through the test scenarios, allowing the data librarian to observe their movements through the repository and to review the recordings later in case anything was missed. testing sessions generally lasted between twenty and thirty minutes, although some lasted from forty-five minutes to one hour. after sessions were completed, the data librarian recorded in text documents a description of all microinteractions and verbal observations testers made about the repository. she later transferred that data to a spreadsheet, listing each criterion individually and manually adding a count of how many testers either reported or were observed to experience the same phenomenon information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 7 (appendix 1). reported phenomena and observed difficulties that users experienced in testing the repository were aggregated and included in the final reported data if at least two testers reported or had the same experience. through these counts the data librarian was able to identify which microinteractions proved most challenging to the testers. discussion manual, qualitative analysis of the user testing data revealed challenges that users faced with inveniordm that were best captured and expressed when observed as microinteractions. though user experience design had been employed extensively in the design of the database, it was the nuances of the interactions that showed where improvements in the design could still be made. almost every functional area of the repository demonstrated a need for increased user input in its design. the results of user exercises testing the various functional areas are described below. user profile screens ease-of-use exercise while most testers did not experience difficulties in locating the login button on the repository’s home page that allowed them to access the user profile portions of the site (9/12 located the button in less than three seconds), most testers (7/12) requested clearer instructions for which username and password to use (e.g., ldap or shibboleth-based credentials), and three-quarters of testers (9/12) inquired about where and how to add information about themselves to their profiles (e.g., professional title, contact information, department and other affiliations, etc.). while the required task consisted simply of logging successfully into one’s profile, the testers rightly discovered and acknowledged that the robust, cris (current research information system)-like features of many repositories’ user profile pages had not yet been fully implemented in inveniordm. finding datasets exercise the next task required testers to perform a search any way they liked in the repository, locate a dataset record, and download the associated data file. whether searching using filters or by entering keywords to find a known item, users were always able to easily identify a data file within a record and download it. a special feature of inveniordm that occasionally made finding a data file to download challenging was that the repository was designed to serve as both a repository for digital files and a data index. the main feature of a data index is that it will store records representing datasets without necessarily storing the datasets themselves. the data index option is crucial for health sciences researchers, who are often motivated to share data files as openly as possible for motivations of reproducibility, open access to scientific data, and compliance with funder mandates, but who cannot always safely deposit data files due to the presence of personally identifiable information (pii) or protected health information as defined by hipaa17 of the human subjects who are involved in their studies. this phenomenon spurred us to create seed records in the repository that represent real clinical studies, for which the data could be made available upon request from the researchers, but for which a data file was not uploaded to the repository. by following the protocol of making this clinical data public as safely as possible, these records were created and tagged with a visibility level of open access. two of the testers stated that they believed that a record tagged as open access implied that a data file was available for download, and many others (10/12) expected either a visual cue or another filter to allow users to hone in on only the dataset record results that contained a deposited data file. information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 8 filter searching exercise searching the repository, particularly via the filters, resulted in some of the most interesting results of the entire testing process. in the testing exercises, users were asked to search for anything they wanted, either narrowing their results from a direct term search or beginning a search from the full record set using the filter options on the left side of the screen. opinions differed among the repository team members and some testers as to whether applying two filters at once to the results of a search would result in an and or or union of the two subsets of results. another way to phrase this scenario would be, that upon the application of one filter, would the search results and other filters update in real time? for instance, if i filtered my search results to include only the deposits of one particular author, and if the file type filter choices still contained, after the filtering action, types including pdfs, xlsx files, doc files, mov files, etc., is it safe to assume that my chosen author deposited all those types of files? (see fig. 3.) or do the filters behave independently of each other? one third of the testers (4/12) said they expected the filtering choices to update in real time and that the application of two filters should result in an and union of results. figure 3. filters available in inveniordm. seven of the twelve testers said that the most helpful of the of the five filters available in the repository at the time were resource type, file type, and subjects, while slightly less found author and license filters helpful. three of the twelve asserted that it would not occur to them to filter on a resource’s license. information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 9 specific record search exercise in the specific record search, users were asked to find a specific paper by a particular author. none of the testers experienced any difficulties or significant delays in bringing up the requested record, which served as a testament both to their searching abilities and to the robustness of the elasticsearch framework utilized in the repository’s infrastructure. ten of the twelve testers mentioned that they found the preformatted citations available with each record helpful, and two of these testers requested an easy way to export the citation in their desired format to endnote. three of the twelve testers experienced a brief initial delay in locating the known record because they still had filters applied in the repository from a previous search. they requested an easy way to clear all previous filters when starting a new search. creating a record exercise as one of the larger user testing tasks, users were provided with a dummy file representing a dataset and asked to deposit and describe it with appropriate metadata using the repository’s cataloging form. the first part of this task involved finding the button that brings the user to the cataloging form, a button which is available from several places in the inveniordm layout (home page, search results page, and profile page). eight of the twelve testers took longer than three seconds to locate this button, termed the “catalog your research” button. two of these eight reported that “catalog” was not the verb they would associate with depositing and describing a data file; to some, “catalog” seemed a library-centric term. on the repository’s record creation page, a space exists to either upload or drag and drop a file, and when this task is done, a large, blue “start upload” button appears that the user must click to begin the file upload. (see fig. 4.) yet despite its size and color, almost half the testers (5/12) did not notice that they had to click it in order to complete the upload of their file and, worse, they often completed the record creation process and published their record without noticing that the file had not uploaded. visual cues were needed to confirm for the user whether a file was successfully uploaded or not. in addition, automatic upload upon browsing and attaching a file or dragging and dropping a file was reported as an expected behavior by many users. information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 10 figure 4. users often missed the blue “start upload” button just beneath the file name. information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe, allen, ferrie, and holmes 11 most users applied descriptive metadata successfully and easily, but some experienced trouble while appending subject metadata to describe the subject matter of their deposits. as the repository is being customized for a health sciences library, subject fields are offered in inveniordm to allow appending both medical subject heading (mesh) terms and terms from faceted application of subject terminology (fast), a vocabulary derived from the library of congress subject headings (lcsh). since the two vocabularies’ terms are offered in separate fields (fast serving as a more universal set of terms to complement the biomedically oriented mesh), users became confused, not knowing which, if either, subject field they should complete. a solution involving a single subject field that queries both the mesh and fast apis is warranted in order to simplify the subject-tagging experience for the user. editing a record exercise editing the record they had just created, the final testing task, proved to be unproblematic for testers. eleven of the twelve found the edit button on their record pages in less than three seconds, and the editing process was reported to be straightforward. one tester observed that they were unable to change their file (i.e., make a version-level change to their record), but this was only because version change functionality had not yet been implemented in the repository. reflection/unguided feedback once all the testing exercises outlined above were completed, testers were asked to talk about the uses for which they might employ a tool like inveniordm. without prompting or suggestions of uses, the testers overwhelmingly stated that they would use the completed repository for the very functions for which most irs are built: storing data files (two users), sharing data for open science or to fulfill funders’ mandates (two users), searching for others’ datasets (four users), creating gray literature collections to showcase their conference presentations and posters (three users), embedding repository-issued dois from their datasets into manuscripts and posters (three users), and storing data in private collections to share with trusted collaborators (four users). this data shows that university faculty and researchers have various specific needs for repository solutions, which can be met if the repositories are designed with these needs in mind. after testing: next steps the user testing experience for inveniordm proved to be a highly enjoyable process for all involved. the tester participants expressed enthusiasm in the process and appreciated the opportunity to share their ideas about the functionality of an ir while it was still in the design stages. the testers’ enthusiasm reinforced the notion that many university faculty members are eager for an intuitive, user-friendly tool that will allow them to store, retrieve, and share their research outputs, as long as the tool is designed with their needs in mind. observation of testers’ microinteractions with galter library’s new institutional repository has helped the local development team to better understand what those needs are. the results of the user testing were presented at the inveniordm product meeting at cern in january 2020. the results were well received and resulted in immediate adjustments to the repository’s development. as development continues into 2021, the repository team at galter health sciences library & learning center will design and manage at least one additional user testing round to ensure that the repository continues to meet its goals of serving key functional requirements of irs while also providing users the best possible experience through each interaction they have with the tool. as user testing sessions demonstrate, there is much room for growth in the achievement of a truly intuitive interface design in even some of the seemingly information technology and libraries march 2021 user testing with microinteractions | gonzales, carson, viger, o’keefe,

more testers. for four tasks seconds were counted as a mark of how easy it was to find a repository element that enabled the task: 1. finding the login button to access user account 2. finding the citation button after the search for a specific record 3. finding the "catalog your research" button 4. finding the "edit record" button. counting of seconds was done with an iphone stopwatch while reviewing the recorded sessions. if finding the required button took the user longer than a generous count of three seconds, it was deemed that the user had a hard time locating the item. user profile

abstract rural public libraries have been relatively understudied when compared to public libraries as a whole. data are available to show that rural libraries lag behind their urban and suburban counterparts in technology service offerings, but the full meaning and effect of such disparities is unclear. the authors combine data from the public library technology and access study with data from smaller studies to provide greater insight to these issues. by filtering these data through the digital inclusion framework, it becomes clear that disparities between rural and nonrural libraries are not merely a problem of weaker technological infrastructure. instead, rural libraries cannot reach their full customer service potential because of lower staffing (but not lower staff dedication) and funding mechanisms that rely primarily on local monies. the authors suggest possible solutions to these disparities while also discussing the barriers that must be overcome before such solutions can be implemented. introduction the large number of rural public libraries in the united states is surprisingly understudied, particularly in terms of technology access. the american library association (ala) and other professional organizations consider a public library to be small or rural if its population of legal service area is 25,000 or less. when viewed through this lens, rural public libraries1 • have on average less than one (.75) librarian with a master’s degree from an alaaccredited institution; • have an average of 1.9 librarians, defined as an employee holding the title of librarian; • have an average total of 4.0 staff, including both fulland part-time employees; • have a median annual income (from all sources) of $118,704.50; • have an average of 41,425 visits annually; and • typically have one building or branch that is open an average of 40 hours/week. brian real (breal@umd.edu) is a phd candidate in the college of information studies, john carlo bertot (jbertot@umd.edu) is co-director of the information policy and access center and professor in the college of information studies, and paul t. jaeger (pjaeger@umd.edu) is codirector of the information policy and access center and associate professor and diversity officer of the college of information studies, university of maryland, college park, maryland. mailto:breal@umd.edu mailto:jbertot@umd.edu mailto:pjaeger@umd.edu rural public libraries and digital inclusion | real, bertot, and jaeger 7 while these data suggest rural libraries operate on a smaller and less financially robust scale than their suburban and urban counterparts, the full effect of these discrepancies on service levels is unclear. this article uses various information sources to analyze the effect of these discrepancies on the ability of rural libraries to offer technology-based services. since the advent of the internet in the mid-1990s, public libraries have been key internet-access and technology-training providers for their communities. the ability to offer internet access alongside support and training for patrons using such technology are primary indicators of libraries’ value to their communities. by analyzing data from the 2012 public library funding and technology access survey (plftas), the authors found that rural libraries, on average, have weaker technological infrastructure (such as fewer average numbers of computers and slower broadband connections) and are able to offer fewer support services, such as training classes, than urban and suburban public libraries. with public libraries being many patrons’ only source of broadband access in many rural communities, limitations for rural libraries may affect patrons’ ability to fully participate in employment, education, government, and other central aspects of society. through analysis of the plftas data2 about technology access in rural public libraries in conjunction with other studies of rural libraries and librarians, this article explores the causes and effects of the relatively more limited technological and support infrastructures for rural patrons and communities. method as documented since 1994,3 public libraries were early adopters of internet-based technologies. the purpose of the pltas survey, and its previous iterations, is to identify public library internet connectivity; propose and promote public library internet policies at the federal level; maintain selected longitudinal data as to the connectivity, services, and deployment of the internet in public libraries; and provide national estimates regarding public library internet connectivity. through changes in funding sources and frequency of administration over the past two decades, the survey has maintained core longitudinal questions (e.g., numbers of public access workstations, bandwidth), but consistently explored a range of emerging topics (e.g., jobs assistance, e-government, emergency roles). the survey’s method has evolved over time to meet changing survey data goals. the 2012 survey provides both national and state estimates of public library internet connectivity, public access technologies, and internet-enabled services and resources. the survey used a stratified “proportionate to size sample” to ensure a proportionate national sample using the fy2009 imls public library dataset (formerly maintained by the us national center for education statistics) to draw its sample. strata included states in which libraries resided and metropolitan status (urban, suburban, rural) designations. bookmobile and books by mail service outlets were removed from the file, leaving 16,776 library outlets. information technology and libraries | march 2014 8 the study team drew a sample with replacement of 8,790 outlets stratified and proportionate by state and metropolitan status state.4 the survey received 7,252 responses for a response rate of 82.5%. using weighted analysis to generate national and state data estimates, the analysis uses the responses to estimate to all public library outlets (minus bookmobiles and books by mail) in the aggregate as well as by metropolitan status designations. unless otherwise noted, all data discussed in the article are from the 2012 study. that study, along with all previous public libraries and the internet and public library funding and technology access studies, additional analysis, and data products are available at http://www.plinternetsurvey.org. digital inclusion and the value of public libraries digital inclusion is a useful framework through which one can understand the importance of ensuring individuals have access to digital technologies as well as the means to learn how to use them.5 digital inclusion comprises policies and actions that mitigate the significant, interrelated problems of the digital divide and digital literacy: • digital divide implies the gap—whether based in socioeconomic status, education, geography, age, ability, language, or other factors—between individuals for whom internet access is readily available and those for whom it is not. indeed, even those with basic, dialup internet access are losing ground as internet and computer technologies continue to advance, using increasing bandwidth and demanding high-speed (“broadband”) internet access. • digital literacy encompasses the skills and abilities necessary for access once the technology is available, including understanding the language and component hardware and software required to successfully navigate the technology. • digital inclusion is policies developed to close the digital divide and promote digital literacy. it marries high-speed internet access (as dial-up access is no longer sufficient) and digital literacy in ways that reach various audiences, many of whom parallel those mentioned within the digital divide debate. to match the current policy language, digital inclusion will signify outreach to unserved and underserved populations. since virtually every public library in the united states offers public internet access, these institutions are invaluable in promoting digital inclusion. however, the plftas data shows that not all libraries are equal, with rural public libraries lagging behind libraries in more populated areas in providing technology services. therefore this article focuses on the following issues and questions: • digital divide: why do rural individuals have less access to broadband technologies than their suburban and urban counterparts? how are rural libraries currently compensating for this deficit? rural public libraries and digital inclusion | real, bertot, and jaeger 9 • digital literacy: why do rural libraries offer less digital literacy training and patron support? how do rural libraries compare to libraries in more populated areas on key issues in digital literacy, such as employment and government information? • digital inclusion: what policies have been developed to help rural libraries close the digital divide and promote digital literacy, and what policies—including funding structures and decisions—hinder these libraries from adequately addressing these concerns? what governmental and extra-governmental policies can be enacted to help rural libraries to better promote digital inclusion? the following section describes the differences between rural libraries and their urban and suburban counterparts, combining plftas data with information from other studies to demonstrate how rural libraries are more essential in bridging the digital divide yet are seemingly doing less to promote digital literacy. following this, the authors discuss why rural libraries trail suburban and urban libraries in these areas, with studies suggesting the issue is a result of inadequate resources, not a lack of staff dedication. finally, the authors present a review of some of the initiatives that are attempting to bridge these divides, including suggestions that may help rural librarians to act as better advocates for their patrons’ needs. rural challenges to digital inclusion numerous studies, including plftas, show that rural libraries offer less technology access with slower connection speeds than libraries in more populated areas. these libraries also offer comparatively less formalized digital literacy training, although rural libraries still provide invaluable informal training in this area. this section highlights discrepancies between rural libraries and those in more populated areas. technology and service disparities between rural and nonrural libraries while almost every public library offers patrons internet access, 70.3% of rural libraries are the only free internet and computer terminal access providers in their service communities, compared to 40.6% of urban and 60.0% of suburban libraries.6 the disparity between these categories becomes more striking when one considers the difference between home broadband adoption in rural and nonrural areas. according to the pew research center’s home broadband 2010 survey, only 50% of rural homes have broadband internet access, compared to 70% of nonrural homes.7 this disparity is due in large part to the greater difficulty and cost of creating the infrastructure to support broadband internet access in more sparsely populated areas.8 with broadband access provided primarily by for-profit companies, little profit motive exists to expand services to areas where the infrastructure cost would not allow for a quick and efficient recouping of costs. the us government has attempted to address this problem in a numerous ways, including dedicating $7.2 billion to improving broadband access throughout the country through grants (broadband information technology and libraries | march 2014 10 technology opportunity programs; btop) and loans (broadband infrastructure projects; bip) as part of the american recovery and reinvestment act (arra) of 2009.9 expanding this infrastructure will take time, and at this time it is unknown as to the extent to which broadband access in rural communities, both in general and for public libraries, will increase. as the arra projects near completion, it will be important to conduct follow-up analysis of the effect in terms of access to broadband in the home and in anchor institutions such as public libraries, as well as the extent to which broadband subscriptions increased. at present, however, public libraries—and rural public libraries in particular—are still the primary source of broadband access for many americans, and this will likely remain true for large portions of the population for the foreseeable future. individuals in need of internet access have few options in many communities. though there are increasing free wireless (wi-fi) internet access sources in communities (e.g., coffee shops, food outlets), one needs to have a device (e.g., tablet, laptop) to use these options. in two-thirds of american communities, the public library is the only source of freely available public internet access inclusive of public access computers.10 specific government efforts to increase internet access, broadband networks, and digital literacy of the population, however, fail to involve public libraries in a meaningful way, if at all.11 to be fair, public libraries were eligible to compete for the grants or submit loan applications for the arra broadband funding initiatives, and public libraries in states such as alaska, arizona, colorado, idaho, maine, montana, nebraska, and others have benefited from this, primarily through inclusion in applications with multiple beneficiaries.12 since btop works as a grantmaking process, relatively few us public libraries (approximately 20%) have benefited from btop funding, but the results have been encouraging. for example, 85 libraries in mostly rural nebraska have upgraded their broadband capacity using btop funds, with broadband capacity for these locations increasing from an average of 2.9 mbps to an average of 18.2 mbps. other states have tried innovative ideas, such as the idaho department of labor’s youth corps program to train high school and college students to work as digital literacy coaches, and then deploy them to libraries around the state. indeed, the btop program has certainly created some encouraging results, but this is not a permanently funded program and it targets a limited number of libraries, so it cannot be considered as a primary, widespread solution to the digital inclusion gap between rural and more populated areas. the authors of a recent btop report note, “unless strategic investments in u.s. public libraries are broadened and secured, libraries will not be able to provide the innovative and critical services their communities need and demand.”13 thus btop may provide a good model to addressing gaps in digital inclusion, but it was never designed to be a permanent solution. this role of ensuring digital inclusion in communities has accelerated at a time of unprecedented austerity nationally and at the state and local levels of government in particular. based on bureau of labor statistics (http://www.bls.gov) data, the united states lost 584,000 public-sector jobs between june 2009 and april 2012, or 2.5% of the local, state, and federal government jobs that rural public libraries and digital inclusion | real, bertot, and jaeger 11 existed before the prolonged economic downturn began. according to the center on budget and policy priorities, state budget shortfalls have ranged from $107 billion to $191 billion between 2009 and 2012, and current projections place state budget shortfalls at $55 billion for 2013.14 the prolonged economic downturn, in part, has driven up library usage in some communities.15 even before the downturn began, public libraries in the rural areas typically had the oldest computing equipment, the slowest internet access speeds, and the lowest support levels from the federal government.16 as a part of becoming the main source of digital literacy training and digital inclusion, public libraries have also become a primary training provider for in-demand, technology-based job skills.17 the resulting situation forces public libraries to balance reduced support, increased demand, and a growing centrality in helping their communities recover from the economic downturn. at the center of both increased demand and increased support of digital literacy and inclusion lies sufficient internet access. in a survey of rural librarians in tennessee, respondents reported that their patrons’ most critical information need was broadband internet access.18 the respondents also ranked access to recent hardware technology and software, technology training, and help with specific tasks like applying for jobs or government benefits as highly critical. by comparison, the respondents ranked traditional services such as book loaning as the least critical duty, significantly trailing the abovementioned and other technology services. despite rural librarians viewing technology-based services as their most important function, however, rural libraries lack the resources to meet the same service quality as nonrural libraries. the ensuing section discusses the nature of those disparities. technology infrastructure and technology training virtually all public libraries offer their patrons access to the internet. there is no statistical difference between rural, suburban, and urban libraries in this regard.19 likewise, rural libraries only lag slightly in wireless internet availability, which is becoming increasingly important with the ubiquity of mobile technology devices; 86.3% of rural libraries have wireless access available for patrons, compared to an average of 90.5% across all three categories.20 and, in one of the few technological areas where rural libraries lead their nonrural counterparts, 42.3% of rural libraries reported they had sufficient public access computer terminals at all times, compared to 33.5% of suburban and 12.9% of urban libraries. while the number of rural library computer terminals may be adequate in many locations, hardware quality suffers; 69.5% of rural libraries replace their public access computer terminals as needed while, 66.4% of urban libraries have a technology replacement schedule.21 for many small libraries with only a single full-time librarian, that employee also serves as the it specialist for the location.22 therefore many rural libraries have less up-to-date technologies and less technical support than their nonrural counterparts. even if the librarians who also provide it support for their locations are qualified to fulfill this role, the greater issue is limited time for information technology and libraries | march 2014 12 librarians to work on these issues in addition to other duties. in addition to less recent hardware, rural libraries also have limited bandwidth; 31.1% of rural libraries operate on bandwidths of 1.5 mbps (t1) or less, compared to only 18.3% of suburban libraries and a mere 9.7% of urban libraries.23 the greatest issues facing rural libraries are not well represented by the broader categories of internet access but instead in the implementation of services to make these technologies highly useful and effective for patrons. only 31.8% of rural libraries offer formal technology training classes, as compared to 63.2% of urban and 54.0% of suburban libraries.24 this comparison alone does not present a problem, since more populated areas have larger customer bases that justify training patrons in groups rather than in one-on-one sessions. however, rural libraries also trail significantly in offering one-on-one technology training, with only 30.1% of rural libraries providing such programs, compared to 43.4% of urban and 37.9% of suburban libraries. only 21.9% of rural libraries have online training materials, compared to 36.3% and 33.7% of urban and suburban libraries, respectively. in fact, 12.5% of rural libraries do not offer planned technology training at all, compared to a mere 5.1% of urban libraries and 8.0% of suburban libraries. therefore, while most patrons in nonrural areas who have limited technology skills can go to their local library and acquire such skills for free, such access to the resources for personal advancement is drastically limited by comparison in rural areas. since many rural residents do not have internet access in their homes, many of these individuals do not own computers and have limited technology skills resulting from limited technology exposure. this makes the technology training disparity between rural and nonrural libraries quite problematic, since most americans need these skills to maintain a high standard of living and employment. employment assistance while public libraries in all areas saw adequate staffing as a statistically similar problem for helping patrons find jobs—51.9% or rural librarians agreed this was a challenge, only slightly exceeding the overall average of 49.8%—the greater issue is the disparity of confidence levels in assisting patrons in employment matters.25 nearly half (48.3%) of rural survey respondents agreed a lack of staff expertise was a challenge to helping patrons find and apply for jobs online, compared to 27.9% of urban and 37.7% of suburban libraries. the internet has become essential for many people who wish to gain employment, thus rural public librarians’ inability to support rural residents with limited technology skills is problematic. many government agencies, hospitals, and private employers—including walmart, the largest employer in the united states—will no longer accept paper applications, but instead insist potential employees submit applications via the internet.26 this can be especially challenging for individuals who have recently lost jobs they have held for decades, as they simultaneously need to refresh basic application and interviewing skills while learning how to use unfamiliar information technologies to find and apply for jobs. librarians can offer critical assistance in these cases, especially for individuals who do not own a computer or have internet access in their homes. however, inequities in staffing between rural rural public libraries and digital inclusion | real, bertot, and jaeger 13 and nonrural libraries can prevent rural residents from having equal access and aid in finding careers. government service access rural libraries also lag behind libraries in more populated areas in providing support for accessing online government services. there is no statistically significant difference between public libraries in staff providing assistance to patrons who need help filling out forms, with 96.6% of all libraries offering this service.27 however, only 45.6% of rural libraries assist customers in understanding government programs and services, compared to 57.8% of urban and 52.9% of rural libraries. rural libraries are also far less likely to have formal guides to help customers understand these government services, with only 15.3% of rural libraries offering such products as compared to 33.6% of urban and 22.2% of suburban counterparts. just 6.2% of rural libraries offer formal training classes for using government websites, understanding government programs, and completing forms. roughly a one-fourth (24.5%) of urban and 11.9% of suburban libraries offer such services. in terms of staff expertise, 20.0% of rural libraries reported having at least one staff member with significant knowledge and expertise of government services, compared to 31.4% of urban and 25.0% of suburban libraries. therefore, while most public libraries help patrons access government services, rural libraries lag substantially in the type of formal planning that may make patrons more aware of government services that would improve their quality of life. important services such as voter registration, motor vehicle services, payment of taxes, and school enrollment for children can now be done either only or much more efficiently online.28 these online services are more convenient for many americans, but “while many members of the public may struggle with accessing or using egovernment information and services, government agencies have come to focus on it as a means of cost savings rather than increasing access for members of the public.”29 government agencies have for the most part not taken many americans' lack of digital literacy into account when shifting their primary means of service to the digital realm, nor have they considered the effect this shift has on public libraries as the primary internet provider for many americans. this has led to extra responsibilities for rural public libraries but not a direct increase in resources. one might consider that rural libraries offer fewer of these services, or have less expertise in providing digital government services, in part because such services are not in demand by patrons. however, government services have steadily moved online and the pace is accelerating towards an e-only means of interacting with government. the open government movement,30 combined with the federal government’s release of the technology and services blueprint, signals the further use of technologies to offer innovative and operational digital government services—both through more traditional web-based services and mobile applications.31 and state and local governments are increasingly engaging in e-government services such as unemployment and social service benefits, taxation, licensing, and more. in short, federal, state, and local governments are moving rapidly to a range of e-services that will necessitate facility by librarians with technologies, information technology and libraries | march 2014 14 government services, and government information to better help their communities navigate the challenges of e-government. government intervention in digital literacy although most government agencies have not considered the effect their shift to primarily digital services has on individuals who lack basic digital literacy, the federal communications commission launched two programs that could help with the digital literacy problem. the first of these, digitalliteracy.gov, is designed to provide individuals with tools to facilitate digital inclusion, helping users to acquire skills that will make them more capable in the modern information environment. the challenge with this approach is that many resources on the website are designed for individuals who need such skills and who therefore probably do not have access to the internet or possess the skills to fully engage the resources. moreover, most of these resource links point to external sites, which are organized by arbitrary user ratings rather than skill level and relevance.32 likewise, educator resources – which should be most valuable in helping librarians to education patrons – are presented as links to external sites with limited information about each resource. these resources may be able to help patrons, but a collaborative effort that includes public librarians in creating resources could better target particular patron needs in a public access setting. a newer project, connect2compete, demonstrated more promising progress in this area. connect2compete is a partnership between the fcc and private businesses to provide low-cost internet and computers to low-income families, digital literacy training, and other services.33 they also publicize the digital literacy divide, working with the ad council and other organizations to promote this issue.34 the website allows users to search for places where they can receive digital literacy training, with the search results primarily displaying local public library branches. however, despite pointing users to public libraries for such training, connect2compete currently only helps to fund such training in limited cases. while this program provides a strong model for raising awareness about digital inclusion, it is unlikely to provide infrastructure resources to fully bridge the gap between rural and nonrural communities in the near future. while the fcc has been innovative by soliciting private funds to prevent connect2compete from using any taxpayer funds, these private funds will not replace the need for government funds for public libraries throughout the nation, nor is private funding likely to continue indefinitely. indeed, “while governments at all levels are relying on public libraries to ensure digital inclusion, the same governments are reducing the funding of the very libraries that are being relied on.”35 the following section will detail how decreasing funding and limited resources have contributed to the digital divide between rural and nonrural libraries. rural libraries and barriers to promoting digital inclusion when the internet was emerging in the 1990s, “public libraries essentially experimented with public-access internet and computer services, largely absorbing this service into existing service rural public libraries and digital inclusion | real, bertot, and jaeger 15 and resource provision without substantial consideration of the management, facilities, staffing, and other implications of public-access technology services and resources.”36 while some libraries have increased their funding levels to match these challenges, most funding agencies have not recognized the costs or value of additional services that public libraries now offer in a wired nation. this section discusses the reasons why rural libraries have not been able to offer the same level of service nonrural library patrons routinely expect. funding inadequacies for rural libraries rural libraries face challenges from their problematic funding structure. sin noted that for public libraries, “on average, the local government provided 76.6% of the funding; the state, 8.7%; the federal government, 0.7%; and other sources, 13.9%.”37 this is a particular problem for rural libraries since, as holt explained, “if cities and suburbs had to survive on the extraordinarily low taxes on agricultural property, the urban/suburban public sector would have service levels so low that most officials would turn away in disgust.”38 this lack of local revenue for all public services—including libraries—in rural areas is exacerbated by the continuing population decrease in small towns and the desirability of such locales for retiring seniors, who prefer to live in areas with low taxes because of limited incomes.39 in other words, public library funding structures that place local governments at the forefront of budgeting plans put rural libraries at a serious disadvantage and promote a digital divide between rural and nonrural areas. holt notes, “it is the legitimate function of state government to make things right. state governments, after all, are of a size and scale that historically allows them to perform as equity agencies for locales.”40 indeed, the averages for funding sources cited above can vary, and state and federal governments have attempted to dampen the funding inequities between rural and nonrural libraries. one example is the federal e-rate program, established under the telecommunications act of 1996 to provide schools, libraries, and healthcare providers with a discounted “education rate” for communication technologies, including internet technologies.41 while this has subsidized part of the internet service costs for libraries throughout the nation, many libraries do not apply because they do not know they are eligible or the application process is too complicated. some rural libraries have had the advantage of their state library systems applying on their behalf, but even when funding is provided this only covers parts of the libraries’ connection and equipment costs. and, according to the plftas survey, only 61.5% of rural libraries received e-rate funds, compared to 75.0% of urban libraries, showing the program does not favor the class of libraries with the greatest connectivity issues.42 likewise, as noted above, the federal government designated $7.2 billion from the american recovery and reinvestment act of 2009 for improving broadband access throughout the nation, with funding designated for rural areas and public libraries in general. these improvements will take time, though, and will not fully compensate for the lack of local funds for rural libraries or rural libraries not receiving nearly as much in nongovernmental funds as nonrural libraries.43 additionally, while local governments in some areas have created their own broadband information technology and libraries | march 2014 16 infrastructure to compensate for corporate providers’ unwillingness to expand to some areas due to inadequate predicted profits, nineteen state governments banned such practices due to lobbying efforts from the broadband industry.44 the corporations that lobbied for these laws feared that if this becomes common practice, local governments could offer low enough pricing to compete against for-profit services. while this may be a legitimate concern, the end result of this legislation is local governments—including rural governments—in some states being legally blocked from allocating funds to solve the market failure that has prevented corporate providers from adequately expanding into rural areas. therefore public libraries’ funding and resource structures are inherently stacked against rural institutions. while e-rate and other federal and state programs may mitigate the problem, the ultimate solution needs to be a restructuring of library funding models that takes the primary burden off struggling local governments or at least increases state and federal contributions. in a seminal article on rural libraries and the technology written in 1995, vavrek noted that “public libraries cannot survive by only appealing to those who are least likely to be able to pay to support the library. while visions of the homeless person using the internet to locate information is both compassionate and within the social role of the public library, can the library afford to provide this access?”45 beyond patrons not being open to assisting less fortunate individuals, vavrek suggested attempts to diversify library services—including introducing internet technology services, which was novel at the time—could distract resources from libraries’ established services that have traditionally appealed to all income classes and, with this, erode public support for these institutions. the pew home broadband 2010 survey show vavrek’s thoughts on this matter were prescient, as 53% of survey respondents believed the government either should not support broadband expansion or that this should not be a very important priority.46 the benefits of greater broadband access and relevant service support may seem obvious to those who are intimate with this matter, but much of the public does not see the importance of expanding such services. if rural librarians cannot fight these perceptions and convince traditional library users and the general public of the importance of these services, then they will probably not be able to reverse these negative trends. unfortunately, rural libraries lack the time, resources, and data to lobby the public on these matters. staffing and training problems for rural librarians a lack of funding and resources affect not only rural public libraries, but also rural public librarians. in a study that illustrated such issues, flatley and wyman surveyed a random sample of libraries in extremely rural areas, with their service population baseline being 2,500 as opposed to the 25,000 threshold noted above.47 while the data they collected are somewhat dated (the survey was conducted in 2007), this study still deserves special attention because similar data have not been collected more recently or by other authors. the authors found that 80% of rural libraries have only a single full-time employee, and 50% have two or less paid employees when fulland part-time employees are considered.48 these rural public libraries and digital inclusion | real, bertot, and jaeger 17 employees are underpaid compared to the national average, with 72% reporting they earned $12.99 or less per hour.49 when asked why they believed their pay was relatively low, more than half (53%) of rural librarians responded it was because their communities lacked funds, demonstrating the structure of local funding being more important than state and federal funding to librarians’ salaries.50 flatley and wyman also found that only 14% of these employees held mls degrees, with 32% having achieved bachelor’s degrees and 37% having completed only a high school diploma.51 as one would expect in relation to most rural librarians not having professional training before entering the field, many of these individuals applied for their first library career because they saw a position advertised for their local library and it offered better pay than most other local jobs. while many rural librarians entered the profession because of reasons other than a desire to become librarians, the data suggest these individuals are capable and enthusiastic about their jobs. almost half (47%) of rural librarians had worked in the field for more than a decade, with an additional 22% having been librarians for six to ten years.52 two-thirds (66%) of survey respondents stated they intended to remain librarians until retirement age, and 97% responded they were very satisfied or somewhat satisfied with their careers.53 additionally, despite the relatively low pay for library positions, this was not the most common complaint rural librarians had about their jobs. instead, while 27% found low pay to be the greatest issue they faced, 29% felt a lack of funds for new materials was a greater problem.54 therefore, while certain technological issues in rural public libraries—such as the lack of technological training courses for patrons—can be framed accurately as a problem involving rural librarians, these problems should not be framed as the librarians’ fault. with current staffing levels, rural librarians do not have as much available staff time to provide training courses and one-on-one training as their suburban and urban counterparts. these librarians may also lack the knowledge and experience to train others in technological skills, and their libraries may lack the funds to help them acquire these abilities. these factors are outside of these librarians’ control, however, and “no matter how hard lis professionals try, one cannot expect public library systems (especially those in less-advantaged neighborhoods) to bridge the information gap when the libraries are themselves underfunded and understaffed.”55 considering typical rural librarians' high dedication levels, one can assume they would be willing to remedy information gaps if they first had the resources to fix their libraries’ skill, funding, and staffing gaps. possible solutions rural libraries face the dual issue of a lack of resources to allow librarians enough time to advocate for their branches and a lack of data that advocates can use to show funders these libraries’ value to their communities. as a solution for the latter problem, sin suggested that library and information science (lis) scholars and other prominent figures in the field begin a dialogue with underfunded libraries—including rural institutions—to work with librarians to gather, process, and interpret data on libraries’ needs and libraries’ effects on their information technology and libraries | march 2014 18 communities.56 this would have the dual benefit of giving librarians better information with which they could focus their services for maximum value and providing graduate-student and professional-level researchers with a stronger understanding of their field. the authors of this article would like to expand on this slightly to suggest that any researchers who draft scholarly papers and presentations from data collected from work with underfunded libraries should feel obligated to assist libraries in using this data for their own benefit. scholars are likely to be in a better position to advocate for libraries with which they collaborate than time-and resourcestrapped librarians, and they should feel an ethical responsibility to do so after reaping the benefits of research. more rural librarians also need the skills to empower them to lead technological training courses for patrons, gather data to better understand how to best optimize their services, and lobby for greater funding at the local level. mehra et al. of the school of information sciences at the university of tennessee attempted to remedy this problem to a limited degree with a program they launched in june 2010 with funding from the imls laura bush 21st century librarian program.57 the researchers used this funding to provide full scholarships—including laptop computers and funds for books—to sixteen rural librarians already working in the south and central appalachia regions, allowing them to earn an mls degree in two years of part-time study. the researchers had previously conducted a qualitative survey of rural librarians in tennessee to determine the training and resource needs of rural librarians,58 and they used these data to form a customized mls program for the scholarship students. this included courses focusing on strong technical competencies, service evaluation, grant writing, and other courses of particular relevance to the rural environment. likewise, georgia uses state funds to pay the salaries of many experienced librarians with mls degrees throughout the state, thereby lifting the burden of affording such individuals off cashstrapped counties and municipalities.59 however, as this system develops in georgia, state funding is still limited and there have been state funding cuts to other areas, such as materials and infrastructure, to allow for an increase in state-funded professional librarians.60 therefore, while this appears to be a promising model that can be of particular benefit to rural residents of the state, further study is needed to determine its overall effects. with an estimate of more than 8,000 rural public libraries operating in the united states,61 it would be impossible to find the resources to provide the large majority of librarians without an mls at these locations with the full training needed to earn the degree. even if such funding were available, a large portion—if not the majority—of these resources could be put to better use by improving rural libraries’ technological infrastructure, increasing salaries, and growing collections. therefore, while the mls may remain the gold standard for library professionalism, it is not a realistic goal for many experienced and dedicated librarians throughout the country. instead, a more realistic program on a larger scale may be to provide rural librarians with targeted online and in-person training to enhance the skills they feel they need to be more successful. faculty and rural public libraries and digital inclusion | real, bertot, and jaeger 19 graduate students in lis academic programs are perhaps the most capable people to lead such training, and they are likely more capable of writing grant proposals to cover the costs of such programs than the rural librarians they could assist. mehra et al. have shown promising progress in this direction,62 and by removing the mls goal (or only expecting it in limited cases), their work could easily be emulated to help lis educators empower librarians throughout the nation. connect2compete, as detailed above, also has the potential to provide a training model for public librarians. the organization plans to create a “digital literacy corps,” comprising individuals who will help train portions of the public in basic digital literacy skills.63 while this program is still in its early phases, the organization plans to include librarians among this corps, training them to be better able to train others. once again, this will be achieved through private funds donated by corporate partners. this is certainly a noble effort and will likely benefit many libraries and their patrons, but “having access to training and being able to take advantage of training are two separate things.”64 connect2compete, digitalliteracy.gov, and other organizations already provide some resources to help rural librarians understand digital literacy issues and provide better training, but librarians have limited time to familiarize themselves with these sources when dealing with their daily duties. for librarians to use current, future, or more refined training resources, the problem of low staffing—and its cause, low funding—must be addressed. since many rural librarians lack the skill or, more importantly, time to lobby for their own libraries, this is a significant area where partner organizations can help. whether these partners are university departments as envisioned by mehra et al. and sin or individuals funded by private donations in the connect2compete model is inconsequential. the important issue is that if these partner groups want to truly help rural libraries bridge the digital divide, these groups will have to contribute a significant portion of their efforts to lobbying to increase library funding enough to improve infrastructure and increase staffing—and, through this, staff time—for training and assisting patrons. as discussed above, the btop program has had success both in increasing technological infrastructure and human infrastructure, with grant funding being used in some cases to bring in temporary staff that is capable of training patrons in digital literacy and to increase training opportunities for patrons using existing staff. given the information above, btop’s holistic approach is certainly encouraging, and the program's use of federal funds has shown how resources from above the local level can serve as an equalizing force. the temporary nature and limited funding of this program, however, make it important to remember this cannot be considered as the primary solution to the digital inclusion problem. conclusion many rural public libraries are the only providers of free broadband internet service and computer terminals for their communities, with these communities having the lowest average proportion of homes with broadband connections. with the internet being essential to receive information technology and libraries | march 2014 20 important government services and to apply for jobs with some of the largest and most ubiquitous employers throughout the nation, the value of the services offered by these libraries cannot be understated. the basic public library funding structure needs to be modified to close the digital inclusion gap between rural and more populated areas. even if local governments remain the primary funding source for public libraries, this contribution cannot remain grossly disproportionate when compared to state and federal support. state and federal governments are already seeing savings by moving access to government services and information online, and these governments will benefit with the better employment rates and better employee competency that comes with a digitally inclusive society. since these governments share in the benefits of digital inclusion, they must also share in the costs. some programs have shown promising results in bolstering rural public libraries and, though this, improving this nation's digital inclusion. these results range from large-scale programs such as btop to smaller programs such as the mls education program initiated by mehra et al. a common element of many of these programs, though, is their temporary nature, showing that funders are not recognizing that as technological innovation continues, new problems in digital inclusion will emerge. for government decision makers to understand the ongoing nature of the digital inclusion problem, rural public librarians and their allies—including academics and other stakeholders— will need to gather better data and provide better advocacy. references 1. , “fy2011 public library (public use) data files,” institute of museum and library services, http://www.imls.gov/research/pls_data_files.aspx. 2.

understanding, selective analysis, and one-way knowledge connection. in this study, we aim to use machine learning to automatically analyze and explore historical documents from a text analysis and visualization perspective. this technology solves the problem of large-scale historical data analysis that is difficult for humans to read and intuitively understand. in this study, we use the historical documents of the qing dynasty hetu dangse, preserved in the archives of liaoning province, as data analysis samples. china’s hetu dangse is the largest qing dynasty thematic archive with manchu and chinese characters in the world. through word frequency analysis, correlation analysis, co-word clustering, word2vec model, and svm (support vector machines) algorithms, we visualize historical documents, reveal the relationships between functions of the government departments in the shengjing area of the qing dynasty, achieve the automatic classification of historical archives, improve the efficient use of historical materials as well as build connections between historical knowledge. through this, archivists can be guided practically in historical materials’ management and compilation. introduction china has a long history documented in numerous archives. at present, various local archive departments preserve large numbers of historical documents from different periods. owing to the development of china’s archive digitization, archive management departments at all levels have established digital archive abstracts, catalogs, and subject indexes of historical documents in their collections realizing online retrieval of historical archives. with in-depth research on chinese history, simple catalog retrieval cannot satisfy researchers’ demand for related knowledge in historical archives. owing to the limitations of the catalog retrieval system, complex catalog data still need to be read manually. however, it is difficult to view the overall picture of the recorded content and impossible to easily distinguish important information in historical materials; this leads to various difficulties, such as the compilation of historical materials for chinese historical researchers. thus, in this study, we aim to use text analysis and visualization methods in machine learning to conduct data mining analysis of historical document data. these methods will help us discover the logical relationships of historical records and their purposes, accomplish visual presentations of historical entities and knowledge discovered in historiography, improve knowledge representation and automatic classification of historical data, and provide valuable information for historical archive researchers. mailto:mikemike248@gmail.com mailto:734665532@qq.com mailto:yug@hit.edu.cn mailto:1367123893@qq.com information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 2 during the process of analyzing traditional manual methods for interpreting historical documents, we find the following phenomena: macro description, single angle, selective analysis, and one-way knowledge connection, among others. for example, the hetu dangse preserved in the liaoning archives contains a total of 1,149 volumes and 127,000 pages, making it difficult to fully grasp and understand the overall content of such documents. relying on manual reading and analysis of entire archives is an unrealistic task. therefore, this paper proposes using machine learning, natural language processing (nlp), and other technologies to address various problems from traditional manual reading. first, information from historical documents can be revealed from different angles, and this allows the content of the documents to be displayed more comprehensively and scientifically through visual charts. second, use of objective quantitative analysis methods, such as text analysis and nlp, prevents subjective interpretations of the same content. third, nlp and other technologies can solve the problem of calculating massive text training data sets while forming systematic knowledge that avoids the omission and one-sided understanding of knowledge in the historical archive. the application of machine learning in historical data analysis has attracted the attention of researchers in management, history, and computer science. tao used the latent dirichlet allocation (lda) topic modeling algorithm to analyze the themes of documents from 1700 to 1800 included in the german archives, providing a more three-dimensional interpretation and explanation of the spiritual world of germany during the eighteenth century.1 chinese scholars kaixu et al. proposed a method of automatic sentence punctuation based on conditional random fields in ancient chinese.2 this method was proved to better solve the problem of automatic punctuation processing compared with the single-layer conditional random field strategy in ancient chinese as tested on the two corpora of the analects and records of the grand historian. swiss and south african scholars stauffer, fischer, and riesen, and chinese scholars wu, wang, and ma used the kws technology and deep reinforcement learning to automatically recognize handwritten pictures in historical documents.3 solar and radovan used the national and university library of slovenia’s historical pictures and maps as research data. using gis technology, they created a novel display method, and interdisciplinary data resource web application to access and research the data.4 chinese scholars dong et al. and polish scholars kuna and kowalski used the webgis technology to conduct efficient management and visualization research on historical data of natural disasters in ancient china and russia. 5 meanwhile, latvian scholars ivanovs and varfolomeyev and dutch scholars schreiber et al. used web technology to develop a web service platform and explored the intelligent environment of cultural heritage service utilization.6 korean scholars kim et al. used machine learning technology to determine the complex relationships between tasks of various classes in a specific historical period through the network of historical figures.7 judging from results in related fields, the semantic analysis and visualization of historical archives in an intelligent way are gradually moving from statistical description to knowledge mining. these results provide theoretical feasibility and practical technical experience for this study. at present, research on historical documents mainly focuses on the retrieval and utilization of historical material databases. since the words, semantics, grammar, and sentence patterns recorded in historical materials differ from modern texts, using data mining technologies such as machine learning and nlp to intelligently identify historical documents and organize historical data will help us more than traditional methods. this requires the cooperation of artificial intelligence and historical researchers to establish an effective method of historical big data information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 3 analysis to achieve the transformation from traditional manual historical document analysis to automatic artificial intelligence analysis methods. in this paper, we use machine learning and data visualization as a tool to identify differently the content of the historical documents from traditional literature reading, reveal valuable information in the content of historical documents, and promote more systematic, efficient, and detailed understanding of the literature. related technology definition to perform text analysis and visualization of the hetu dangse, we use machine learning technology such as word vector processing, the svm (support vector machines) model and network analysis. word vector is a numerical vector representation of a word’s literal and implicit meaning.8 we segmented the hetu dangse’s catalog data and used the word2vec model to transform the segmented data’s word vector form into a set of 50-dimensional numerical vectors representing a catalog’s vector data set. to accurately visualize historical document records’ relationship features, we reduced the vector data set’s dimensionality. dimensionality reduction, or dimension reduction, is data’s transformation from a highinto a low-dimensional space so that the representation retains some of the original data’s meaningful properties, ideally close to its intrinsic dimension.9 after dimensionality reduction, each catalog data in the vector data set is reduced from 50 to 2 dimensions to facilitate flat display. we used the svm model and network analysis technology to analyze the vector data set. the svm model is a set of supervised learning methods used for classification, regression, and outlier detection.10 it is given a vector data set as training to represent historical document records as points in space, and learns independently through the kernel algorithm. using the algorithm, it maps the separated new records to the same space, and predicts their category based on which side of the interval they fall. network analysis techniques derive from network theory, a computer science system demonstrating social networks’ powerful influences. network analysis technology’s characteristics determine that it is suitable for books and historical archives’ visualization in the library and information science field, because the visualization technique involves mapping entities’ relationships based on the symmetry or asymmetry of their relative proximity.11 thus, it helps to discover historical documents’ knowledge relevance. for example, citation network analysis can identify emerging relationships in healthcare domain journals.12 sample data preprocessing and classification this study uses the catalog of the qing dynasty historical archives from the hetu dangse collected by the liaoning archives as the research sample to conduct text analysis and visualization research. china’s hetu dangse is the largest qing dynasty thematic archive with manchu and chinese characters both in domestic and international. the hetu dangse is the official document of communication between shengjing general yamen, the wubu of shengjing and fengtian office, and the document communicated between the beijing internal affairs office in charge and the liubu of beijing during the qing dynasty. the hetu dangse was published from 2015 to 2018, including the hetu dangse·kangxi period (56 volumes), hetu dangse·yongzheng period (30 volumes), hetu dangse·qianlong period (24 volumes), hetu dangse·qianlong period (17 volumes), hetu dangse·daoguang period (52 volumes), hetu dangse·jiaqing period (58 volumes), hetu dangse·qianlong period official documents (46 volumes), hetu dangse·qianlong period official documents (46 volumes), and hetu dangse·general list (16 volumes).13 the hetu dangse is an information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 4 important document for studying the history of the qing dynasty. owing to the special status of shengjing in the qing dynasty, it has a unique historical significance as the companion capital of beijing and the hometown of the qing royal family. this provides original evidence from this time for studying politics, economy, culture, history, and natural ecology in northeast china. in this study, we preprocess the catalog data of the hetu dangse by performing text segmentation, creating a corpus, and labeling data before using text analysis and visualization technology to analyze the catalog data of hetu dangse. first, we use word frequency analysis and statistics to study the functions of institutions. second, we use the co-word clustering algorithm to quantify and visualize the institutional relationships. finally, we use the svm model to automatically classify and explore the catalog data of the hetu dangse. figure 1 illustrates this process. figure 1. text analysis flowchart. data preparation and preprocessing we collected 95,680 catalog data items in the hetu dangse of the liaoning archives, including 25,148 items from the kangxi period; 1,096 items from the yongzheng period; 23,819 items from the qianlong period; 20,730 items from the jiaqing period; and 15,887 items from the daoguang period. the content of each catalog data includes three parts: title information, time of publication (chinese lunar calendar), and responsible agency. the proportion for each period was not evenly distributed in the catalog data of the hetu dangse with the kangxi period catalog data having the highest proportion (26.2%). through the catalog data information, we can perform an in -depth analysis of the content of the hetu dangse from the three perspectives: institutional functions, institutional relationships, and topic classification. data cleaning as the text recorded in the archives of the hetu dangse are manchu and ancient chinese, using chinese word segmentation tools (jieba, snownlp, thulac, etc.) based on modern chinese will cause errors. therefore, it is necessary to construct a special text corpus for word segmentation. first, we construct a stop vocabulary list to remove words with little impact on semantics in the hetu dangse, such as for (为), please (请) and of (之). second, we use the word segmentation tools mentioned above for preliminary word segmentation and then perform part-of-speech tagging and word segmentation corrections based on the word segmentation results. the title part of the catalog data of the hetu dangse mainly contains three dimensions of information: the record title of the catalog, issuing institution, and receiving institution. accordingly, we set a total of four types of tags in the text corpus: issuing institution, receiving institution, record type, and keywords. the receiving institution and the issuing institution correspond to the institutions at the beginning and the end of the catalog, respectively, such as the words shengjing zhangguan fang zuoling, and shengjing ministry of justice. the record type is the front word of the receiving institution, such as counseling (咨) and please (请). the keywords are words that can represent the overall semantics information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 5 in the record title of the catalog, such as arrest (缉拿) and advance (进送). table 1 presents the

multiple angles, we use a supervised machine learning method to automatically classify the catalog data of the hetu dangse. therefore, the original catalog data set must be labeled. we determine the classification and label of the hetu dangse catalog according to the chinese archives classification law, chapter 12. table 2 presents the 11 categories of the catalog. with this, we complete the hetu dangse catalog sampling classification and labeling laying the foundation for automatic catalog classification. the hetu dangse has a total of 95,680 catalog records involving five periods: kangxi, yongzheng, qianlong, jiaqing, and daoguang. we randomly select 500 records from each period and manually label these 2,500 records as the sample data set. the data classification after manual labeling is shown in figure 2. the overall distribution is relatively even, making it suitable for machine learning processing. information technology and libraries september 2021 text analysis and

results in this study, we used the catalog data of the hetu dangse as a sample to analyze and reveal the hetu dangse catalog data from three perspectives: institutional function, institutional relationship, and automatic classification. this will improve usage efficiency of the hetu dangse, thus improving information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 7 researchers’ mastery of relevant information about the document. to achieve the functional requirements of text analysis, we adopted four methods: word vector conversion, word frequency analysis, co-word clustering, and the svm model. word vector conversion of text catalog data the automatic classification of machine-learning technology is based on vector data sets. thus, the hetu dangse text catalog data set must be vectorized before automatic classification. currently, word vector conversion technology mainly includes methods such as one-hot, word2vec, and glove. hetu dangse records the history of the qing dynasty for more than 200 years. there are inevitable relationships among the contents recorded in the documents, indicating that they are not isolated from each other. the word2vec model provides an efficient implementation of cbow and skip-gram architectures for computing vector representations of words, both of which are simple neural network models with one hidden layer. the word2vec model produces word vectors as outputs from inputting the text corpus. this method generates a vocabulary from the input words and then learns the word vectors via backpropagation and stochastic gradient descent.14 this makes the word2vec model more suitable for catalog data from hetu dangse. word2vec includes the cbow model and the skip-gram model, which can enrich the semantic relevance depending on the context, and it is more suitable for the semantic relevance of historical documents such as the hetu dangse. therefore, we adopt the skip-gram model to analyze the catalog data of hetu dangse. we extracted the features of word vectors in catalog data from the corpus, input them into the word2vec model, imported the gensim library in python, trained the vector embeddings, and obtained the htd.model.bin vector file and htd.text.model model file. the correlation between each word in the hetu dangse catalog can be found by implementing the model. for example, if the word bannerman (旗人) is input into the model, the most relevant words are minren (民人, with 0.84726 relevance), accused (被控, with 0.812017), and robbery (抢 劫, with 0.795359). to visualize the ethnic relationships recorded in the hetu dangse catalog, we input the first 300 words of the word vector into the trained word2vec model and performed dimensionality reduction to realize a planar graph. to understand the structure of the data intuitively, we used the t-sne algorithm to reduce the dimensions of the word vector. the t-sne is a type of nonlinear dimensionality reduction used to ensure that similar data points in high-dimensional space are as close as possible in low-dimensional space. we set the embedded space dimension parameter of tsne to 2 and the initialization parameter as pca. this makes it more globally stable than random initialization. the maximum number of optimization iterations is 5,000. figure 3 presents the results. in figure 3, the terms sanling, yongling, zhaoling, prime minister, and fuling form clusters. in shengjing, the qing set up the sanling prime minister's office, and the prime minister's mausoleum affairs minister was appointed concurrently by general shengjing. near fujinmen, the sanling prime minister's office was established. in the 30th year of guangxu, the government office was changed to the prime minister's office of shengjing mausoleum affairs, and the governor of the three provinces concurrently served. under the sanling prime minister’s office, the sanling office was set up to undertake the sacrifice and repair affairs of the three tombs (xinbin yongling, shenyang fuling, and zhaoling).15 therefore, the clustering in figure 3 verifies the close relationship between the sanling prime minister's office and the tombs. information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 8 figure 3. 2d tsne visualization of word2vec vectors. analysis of the relationship between the documents received and sent of the institution with the statistics of the text data obtained after word segmentation, we can find the quantitative relationship between the documents received and sent by the institution, using the pearson correlation coefficient to judge whether there is a correlation between the number of documents received and the number of documents sent by the same institution. 𝜌(𝑟,𝑠) = 𝑐𝑜𝑣(𝑅,𝑆) 𝜎𝑟 𝜎𝑠 (3.1) we suppose that the pearson correlation coefficient between the number of documents received and the number of documents sent is ρ(r,s), r= {r1, r2, r3...r11}. here, r is the variable set of documents received from the institutional sample. set s= {s1, s2, s3…s11} is the variable set of documents sent by the institutional sample. by dividing the covariance of r and s by the product of their respective standard deviations, we can obtain the value of the correlation coefficient of the documents sent and received by the same institution. mining the relationship between institutions’ sending and receiving documents based on co-word clustering to mine the relationship between the institutions’ sending and receiving documents, we adopt a co-word clustering algorithm to generate a visualized network map of institutional relationships. the global co-occurrence rate represents the probability of two words appearing together in all the data sets. in large-scale data sets, if two words often appear together in the text, these two words are considered to be strongly related to the semantics.16 clustering is a method that places objects into a group by similarity or dissimilarity. thus, keywords with high correlation to each other tend to be placed in the same cluster. social network analysis, which evaluates the unique structure of interrelationships among individuals, has been extensively used in social science, psychological science, management science, and scientometrics. 17 we can obtain a sociogram from the institutional function analysis. the main purpose of the sociogram is to provide information information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 9 about the relationship between institutions’ sending and receiving documents. in the sociogram, each member of a network is described by a “vertex” or “node.” vertices represent high-frequency words, and the sizes of the nodes indicate the occurrence frequency. the smaller the size of a node, the lower the occurrence frequency. lines depict the relationships between two institutions. they exist between two keywords, indicating that they received or sent documents to each other. the thickness is proportional to the correlation between the keywords. the thicker the line between the two keywords, the stronger the connection. using this rationale, the map visualization and network characteristics (centrality, density, core-periphery structure, strategic diagram, and network chart) were obtained by analyzing pearson’s correlation matrix or other similarity matrices.18 in this study, we conducted network analysis on a binary matrix to display the relationships between the documents sent and received by the institutions in the shengjing area during the qing dynasty recorded in the hetu dangse. further, we extracted the receiving institution and issuing institution from each record of catalog data in the hetu dangse, and then we composed a new data set with the following data from the receiving institution: issuing institution and title content. we used python to convert the new data set to endnote format and import it into vosviewer1.6.15 to calculate and draw a visual map of the new data set. van eck and waltman of the netherlands’ leiden university developed vosviewer, a metrological analysis software used for constructing and visualizing network graphs.19 although the software’s development principle is based on documents’ co-citation principles, it can be applied to the construction of data network knowledge graphs in various fields. combined with the co -word clustering algorithm, we can create an entity connection network map for historical documents through vosviewer software to reflect the recorded content. automatic classification method of historical archives catalog based on the svm model we used the svm model in machine learning for automatic classification. the svm model has the advantages of strong generalization, low error rate, strong learning ability, and support for small sample data sets, making it suitable for historical archive catalog data samples with small sample characteristics. therefore, we attempted to classify the catalog data set of hetu dangse using the svm model. first, we divided the vectorized labeled data set into a training set and a testing set. the training set accounts for 70% of the data, and the testing set accounts for 30%. to ensure the accuracy of the model prediction, we adopted a random division method to avoid overfitting. second, we used a linear kernel in the svm model and grid search to find the best parameter. various combinations of the penalty coefficient (c) and gamma parameter in the svm model were tested based on their accuracy ranked from high to low. we then determined the best parameter combination. after the model was established, we validated the predictive performance of the model from multiple perspectives such as precision, recall, and f1 score to ensure the generalization ability and availability of the model. we set the penalty coefficients to 10, 100, 200, and 300, while the gamma parameters are set to 0.1, 0.25, 0.5, and 0.75. we used the precision evaluation criteria to find the optimal parameter combination of the model and then imported them. the penalty coefficient is set to the x-axis, the gamma parameter set to the y-axis, and the precision set to the z-axis. we implemented the model to obtain the visualization that is shown in figure 4. clearly, the optimal parameter combination is a penalty coefficient of 10 and a gamma parameter of 0.075. information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 10 figure 4. svm grid search parameter tuning diagram. discussion the history of a nation is the foundation on which it is built. historical documents are the witnesses and recorders of history. through the study of historical documents, we can go back to the past, cherish the present, and look forward to the future. an increasing number of scholars have studied these documents in recent years due to their importance. the hetu dangse records the document communications between institutions in shengjing (now shenyang) and beijing during the qing dynasty. it is an important historical document that cannot be ignored when information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 11 studying the history of northeast china during the qing dynasty. here, we use the catalog data of the hetu dangse as the sample data to test the machine learning methods previously mentioned. we explore the results from the perspectives of institutional function, institutional relationship, and automatic classification to determine the feasibility of our methods. functions of institutions the number of institutions involved in the hetu dangse is over 150. these functional departments formed the governance system of the shengjing area during the qing dynasty. to gain a deeper understanding of the qing dynasty’s ruling system in the shengjing area, the functions of these institutions should be examined. this study analyzes and studies the functions of the institutions in the shengjing area through the number of documents and the frequency of content of the sending and receiving institutions. analysis of the number of documents received and sent by institutions by sorting and statistically analyzing the catalog data of hetu dangse, we obtained data on the number of documents received and sent by institutions in the shengjing area recorded in the hetu dangse. we set the vertical axis as the total number of communicated documents, number of issued documents, and number of received documents. we set the horizontal axis as the names of the institutions and then drew a histogram. this study analyzes the number of institutional archives of the hetu dangse catalog from three perspectives: total number of sent and received documents, number of received documents, and number of issued documents to find the institutions with the highest research value in the shengjing area. in the histogram shown in figure 5(a), the top three institutions in total number of communicated documents are shengjing internal affairs office, shengjing zuoling, and shengjing ministry of revenue. we can also observe that the top 10 institutions have different volumes of their respective documents received and sent by institutions. therefore, the ranking of the total number of communicated documents is not directly related to the respective rankings of the number of documents received and the number of documents sent. in figure 5(b), we can observe that the top three institutions in number of documents received in the hetu dangse are shengjing internal affairs office, shengjing ministry of revenue, and shengjing general yamen. figure 5(c) shows the top three institutions in number of documents sent in the hetu dangse are shengjing internal affairs office, shengjing zuoling, and shengjing general yamen. the total number of communicated documents, number of documents sent, and number of documents received by the shengjing internal affairs office all rank first; this indicates that the shengjing internal affairs office is the most important department of the ruling system in the qing dynasty during the shengjing area. information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 12 figure 5. number of documents received and sent by institutions. a b c information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 13 by using the number of documents received and sent by the institutions, we calculated the pearson correlation coefficient to determine if the number of documents received and sent by the same institution is relevant. as institutional samples, we selected the shengjing internal affairs office, shengjing ministry of revenue, (beijing) internal affairs office in charge, shengjing zuoling, shengjing ministry of works, shengjing ministry of justice, shengjing general yamen, shengjing close defense zuoling, shengjing ministry of war, fengtian general yamen, and shengjing ministry of rites. through calculation, the result of pearson correlation coefficient is 0.69 (save two decimal places), so there is a correlation between the number of sent and received documents, as shown in figure 6. figure 6. scatter plot of pearson correlation coefficient. the hetu dangse is a copy of official documents dealing with the royal affairs of the shengjing internal affairs office during the qing dynasty. it contains the official documents between the shengjing internal affairs office and the beijing internal affairs office in charge, the liubu, etc. and the local shengjing general yamen, fengtian office, the wubu of shengjing, and other yamens.16 thus, there exist a large stock of documents with the shengjing internal affairs office as the sending and receiving agency. the wubu of shengjing, shengjing general yamen, shengjing zuoling, and other institutions are important hubs for the operation of institutions in shengjing. they played an important role in maintaining and stabilizing the society of shengjing. the number of documents is second in importance only to the shengjing internal affairs office. analysis of the frequency of documents received and sent by institutions to further explore the functions of institutions with research value, we extracted the contents of the catalogs from the top three institutions in total number of documents sent and received: shengjing internal affairs office, shengjing ministry of revenue, and shengjing zuoling. we then classified the catalogs of the aforementioned institutions according to receipts and postings. subsequently, we used word segmentation and word frequency statistics to process the two types information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 14 of catalog information and draw comparison diagrams to explore their specific functions in the hetu dangse. as shown in figure 7, we can roughly divide the obtained segmentation words into two categories. one is the name of the communicated official document institutions, such as the ministry of revenue, the ministry of justice, and the ministry of rites on the side of the word frequency (see fig. 7[a]). the other is the name of the official document content and the words zhuangtou (庄头), dimu (地亩), and zhuangding (壮丁) on the side of the frequency of the words in the documents sent. through a comparative analysis of the top 10 words received and sent by the same institution, we conclude that the institutions with a close relationship between receiving and sending documents are not the same. for example, the ministry of revenue of shengjing internal affairs office ranks first in the frequency of documents sent by institutions, while the shengjing zuoling ranks first for receiving institutions (see fig. 7[b]). the contents of documents sent and received by the same institution are different. figure 7(c) shows how the affairs sent by shengjing zuoling to ula (乌拉), forage (粮草), and license (执照) differ from those represented by the zhuangtou (庄头), accounting (会计), and close defense (关防) in the frequency of documents sent and frequency of receipts, respectively. based on previous research on the functions of shengjing’s institutions, the shengjing internal affairs office was set up in the companion capital of shengjing during the qing dynasty to be in charge of shengjing cemetery, sacrifice, organization of staff transfer, and other matters. 20 this relates to the meaning of words such as sacrifice (祭祀) in figure 7(a). the functions of the shengjing ministry of revenue were represented in guangxu’s great qing huidian. the cashiers in charge of taxation in shengjing, number of annual losses in official villages, and banner land were carefully recorded. the expenditures were distinguished and the accounting obeyed the regulations according to the beijing ministry of revenue at the end of the year.21 this is related to the meaning of words, such as dimu (地亩), land sale (卖地), and money and grain (钱粮) in figure 7(b). in fu yonggong and guan jialu’s research of shengjing zuoling’s functions, shengjing zuoling handled the transfer communicated documents; supervised and urged the various departments of guangchu, duyu, zhangyi, accounting, construction, and qingfeng to undertake matters; managed officials and various people; maintained the shengjing palace and the warehouse; selected women to send to beijing inspect; heard all types of cases; undertook the emperor’s general letter; managed the ula people and tributes; and accepted the emperor or the internal affairs office in charge, among other

technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 16 institutional relationship analysis to further study the governance structure of the shengjing area, we not only need to understand the functions of each institution but also explore the overlap between functions of institutions. the catalog data of the hetu dangse consist of three parts: receiving institutions, issuing institutions, and record title of the catalog. a document often includes two institutions, th e receiving institution and the issuing institution, and it is certain that the content of a document relates closely to the functions between the two institutions. by observing the closeness between the number of institutions through visualizations, we conducted a quantitative analysis of consistent catalog data of the receiving and issuing institutions in the hetu dangse to provide reliable data for further research in the intersection of institutional functions in shengjing area. results of institutional connection analysis using the co-word clustering algorithm, we counted the number of archive catalog data consistent with the receiving and issuing institutions. we set the vertical axis as the issuing institution and the horizontal axis as the receiving institution to obtain figure 8. the numbers inside the boxes represent the quantity of catalog data that are consistent with the issuing institution. to facilitate measurements in the statistical process, records less than or equal to 50 communicated documents between the receiving institution and the issuing institution have been zeroed out. as shown in figure 8, the institutions having close relations with the documents recorded in the hetu dangse are concentrated in the issuing institutions shengjing zuoling and shengjing internal affairs office, and the receiving institutions shengjing internal affairs office and shengjing zuoling. among the receiving institutions, the number of documents received by the shengjing internal affairs office from shengjing general yamen reached as high as 11,936. the top three documents received by shengjing zuoling were fengtian general yamen (2,265 pieces), shengjing ministry of revenue (1,527 pieces), and shengjing ministry of justice (1,520 pieces). it is worth noting that there are less than 50 documents from shengjing zuoling in the shengjing internal affairs office. the overlapping functions of the institutions in the shengjing area enabled individual offices to play bureaucratic games, passing responsibility to other offices, leading to low efficiency in handling affairs. for example, the military and political power in the shengjing area was jointly controlled by the shengjing general office and the shengjing ministry of war. the shengjing area’s tax power was controlled by the shengjing ministry of revenue and fengtian office and their subordinate offices. this phenomenon ran through the entire qing dynasty. research on the cr ossfunctionality of institutions has always been a hot topic in qing historiography. by analyzing the official documents between the institutional functions, we can further explore the overlap as well as the advantages and disadvantages of the qing dynasty shengjing ruling system to study the history of shengjing institutions in the qing dynasty more thoroughly providing a reference for the design of current institutions. information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 17 figure 8. relationship of communicated documents by the hetu dangse institutions diagram. visualization of institutional network map we used the hetu dangse catalog as sample data and the co-word clustering algorithm to obtain the close relationship between institutions and the appearance frequency of institutions. we drew a visual network diagram by virtue of vosviewer1.6.15 to obtain figure 9. in figure 9, institutions are represented by default as a circle with their names. the size of the label and the circle of an institution are determined by the weight of the item. the higher the weight of an item, the larger the label and the circle of the item. for some items, labels may not be displayed to avoid overlapping labels. the color of an institution is determined by the cluster the institutions belong to, and lines between items represent links. as shown in figure 9, the relationships between the institutions and departments in the hetu dangse form three core groups: the shengjing internal affairs office (in charge), shengjing zuoling, and beijing internal affairs office in charge. however, the relationships between the three groups are not similar; the distance between the group (beijing) internal affairs office in charge and the two other groups is relatively large. the group at the core of shengjing internal affairs office and the group at the core of shengjing zuoling are closely connected to each other through the wubu of information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 18 shengjing (shengjing ministry of revenue, shengjing ministry of rites, shengjing ministry of war, shengjing ministry of justice, and shengjing ministry of works). further, there are two larger individuals: fengtian general yamen and shengjing general yamen. fengtian general yamen and shengjing zuoling are closely related to each other, and the relationship between shengjing general yamen and shengjing internal affairs office is relatively close. figure 9. co-occurrence of institutions network map. the city of shengjing was the companion capital of the qing dynasty. the qing government implemented special governance measures in these areas that differed greatly from those of direct inland provinces.23 to ensure the stable rule of the shengjing area, the qing dynasty performed the following tasks. first, the qing dynasty set up a general garrison as the highest military and political chief in the shengjing area to be responsible for all military and political affairs within its jurisdiction. second, they established the fengtian office, a capital of the same level as the shuntian office, to rule the common people of the shengjing area. the states and counties, as well as the garrison banner officer, which was under the rule of general garrison, were local administrative institutions under the fengtian office. these institutions implemented the dual management rule of the bannerman and common people. third, as the companion capital, the shengjing area followed the ming dynasty companion capital system to set up the wubu of shengjing to maintain power. in addition, the shengjing internal affairs office, which was in charge of palace affairs, communicated with the beijing internal affairs office in charge. information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 19 results of automatic classification analysis catalogs are important information resources in the field of historical archives. the classification of archival catalogs can not only link relevant information in archives or archive fonds, improve researchers’ utilization efficiency, and save time to search for required archives, but it can also be shown to readers in clusters. as the hetu dangse catalog is a series of historical documents stored for a long period of time, its original classification system does not suit well existing archival management methods. the hetu dangse has a total of 1,149 volumes and 127,000 pages. each volume contains a different number of documents and the ink characters on chinese art paper are in manchu and chinese. reading and categorizing the full text of the hetu dangse not only requires a lot of manpower, material, and financial resources but also extremely high requirements for the classified staff. they need to possess a good knowledge of manchu, archival science, document taxonomy, and other related disciplines. therefore, sorting and organizing the content of the hetu dangse is an impractical task that relies on manual reading and comprehension. to address this problem, we used the svm model of machine learning to automatically classify and explore the catalog data of the hetu dangse. this model further demonstrates the relevance of the knowledge between documents in the hetu dangse and facilitates an in-depth analysis. we imported the vectorized labeled data set into the svm model and selected the optimal parameter combination to run the model. to visualize the data results, the 50-dimensional word vector is reduced to a 2-dimensional word vector using the t-distributed random neighborhood embedding algorithm. we used the svm model to establish a hyperplane visualized in 2dimensional form. the legend only in figure 10 shows the data distribution of the six categories with the highest proportion owing to the large number of categorized data. to test the classification effect of the svm model, we used precision and recall as metrics and calculated the f1 score to validate the model. the results are presented in table 3. based on the created svm model, 95,680 catalog data of the hetu dangse were predicted and classified. the results are shown in figure 11. although there exist certain deficiencies in accuracy and other aspects, it a positive impact for the content research, management, utilization, and retrieval discovery of hetu dangse. table 3. svm model validation parameters result precision 0.736 recall 0.717 f1 score 0.716 information technology and

classification. conclusion in this study, we used machine learning to analyze and visualize the catalog data of the hetu dangse, revealing the functional relationship of the qing dynasty, shengjing regional institutions recorded in this historical document, and showing the institutional communicated relationships. using the svm model, we achieved automatic classification of the hetu dangse catalog from the category perspective. owing to the massive archives of historical materials in ancient china, the information technology and libraries september 2021 text analysis and visualization research on the hetu dangse | wang, wu, yu, and song 21 fonts of many historical materials cannot be recognized by computers or humans. the digitization of catalogs has become a digital bridge between researchers and historical documents. this not only achieves the concise summary and refinement of them but also greatly improves the utilization efficiency by researchers. the svm model can “learn” through the labeled sample data and realize automatic classification of large amounts of unlabeled catalog data. by automatic classification of catalog data, historical data researchers and archive managers can use and manage a large number of historical documents and catalog data more effectively, greatly increasing their utilization. the co-occurrence algorithm can reveal the rules written by the catalog data itself, discover the distance between the catalog data, and form clusters providing a clearer direction for researchers to use historical documents. the algorithm also saves time for researchers to identify documents without purpose, making content presentation of historical documents to readers clearer. this paper improves archivists’ awareness of archive data compilation and management. first, data is observed, topics are identified, and potential relationships between these are found and established to improve historical archives’ compilation. second, the visual presentation method and carrier is chosen, and via the web browser established relationships are visualized for the users to access and utilize. it can be said that scientometric research method can promote the transformation of historical research and archives management and compilation research from traditional explanatory scholarship to truth-seeking scholarship. currently, the application of machine learning technology has gradually extended from applied disciplines to traditional fields of literature, art, and sociology. however, there are still many opportunities in the field of historical research. this study used methods in the field of artificial intelligence to conduct text mining and visualize the presentation of historical archive document catalog data and proposes a new digital and intelligent solution for researching chinese historical documents. with the development of science and technology, research methods for historical documents are undergoing constant changes from the traditional manual subjective analysis of historical data to relying on quantitative analysis represented by deep learning and data mining technology. it is an irreversible trend to research historical documents more comprehensively, accurately, and scientifically by means of artificial intelligence and other technologies on the scientific frontier. for future work, we plan to conduct research on the qing dynasty historical documents from a deeper semantic analysis level, construct a knowledge graph through the method of named entity recognition, and construct an ontological model transforming historical documents into a structured knowledge base to discover new knowledge from historical documents in an automated manner. acknowledgments funding statement this

library catalog | yang and hofmann 141 sharon q. yang and melissa a. hofmann the next generation library catalog: a comparative study of the opacs of koha, evergreen, and voyager open source has been the center of attention in the library world for the past several years. koha and evergreen are the two major open-source integrated library systems (ilss), and they continue to grow in maturity and popularity. the question remains as to how much we have achieved in open-source development toward the next-generation catalog compared to commercial systems. little has been written in the library literature to answer this question. this paper intends to answer this question by comparing the next-generation features of the opacs of two open-source ilss (koha and evergreen) and one proprietary ils (voyager’s webvoyage). m uch discussion has occurred lately on the nextgeneration library catalog, sometimes referred to as the library 2.0 catalog or “the third generation catalog.”1 different and even conflicting expectations exist as to what the next-generation library catalog comprises: in two sentences, this catalog is not really a catalog at all but more like a tool designed to make it easier for students to learn, teachers to instruct, and scholars to do research. it provides its intended audience with a more effective means for finding and using data and information.2 such expectations, despite their vagueness, eventually took concrete form in 2007.3 among the most prominent features of the next-generation catalog are a simple keyword search box, enhanced browsing possibilities, spelling corrections, relevance ranking, faceted navigation, federated search, user contribution, and enriched content, just to mention a few. over the past three years, libraries, vendors, and open-source communities have intensified their efforts to develop opacs with advanced features. the next-generation catalog is becoming the current catalog. the library community welcomes open-source integrated library systems (ilss) with open arms, as evidenced by the increasing number of libraries and library consortia that have adopted or are considering opensource options, such as koha, evergreen, and the open library environment project (ole project). librarians see a golden opportunity to add features to a system that will take years for a proprietary vendor to develop. open-source opacs, especially that of koha, seem to be more innovative than their long-established proprietary counterparts, as our investigation shows in this paper. threatened by this phenomenon, ils vendors have rushed to improve their opacs, modeling them after the next-generation catalog. for example, ex libris pushed out its new opac, webvoyage 7.0, in august of 2008 to give its opac a modern touch. one interesting question remains. in a competition for a modernized opac, which opac is closest to our visions for the next-generation library catalog: opensource or proprietary? the comparative study described in this article was conducted in the hope of yielding some information on this topic. for libraries facing options between open-source and proprietary systems, “a thorough process of evaluating an integrated library system (ils) today would not be complete without also weighing the open source ils products against their proprietary counterparts.”3 ■■ scope and purpose of the study the purpose of the study is to determine which opac of the three ilss—koha, evergreen, or webvoyage—offers more in terms of services and is more comparable to the next-generation library catalog. the three systems include two open-source and one proprietary ilss. koha and evergreen are chosen because they are the two most popular and fully developed open-source ilss in north america. at the time of the study, koha had 936 implementations worldwide; evergreen had 543 library users.4 we chose webvoyage for comparison because it is the opac of the voyager ils by ex libris, the biggest ils vendor in terms of personnel and marketplace.5 it also is one of the more popular ilss in north america, with a customer base of 1,424 libraries, most of which are academic.6 as the sample only includes three ilss, the study is very limited in scope, and the findings cannot be extrapolated to all open-source and proprietary catalogs. but, hopefully, readers will gain some insight into how much progress libraries, vendors, and open-source communities have achieved toward the next-generation catalog. ■■ literature review a review of the library literature found two relevant studies on the comparison of opacs in recent years. the first study was conducted by two librarians in slovenia investigating how much progress libraries had made toward the next-generation catalog.7 six online catalogs sharon q. yang (yangs@rider.edu) is systems librarian and melissa a. hofmann (mhofmann@rider.edu) is bibliographic control librarian, rider university. 142 information technology and libraries | september 2010 were examined and evaluated, including worldcat, the slovene union catalog cobiss, and those of four public libraries in the united states. the study also compared services provided by the library catalogs in the sample with those offered by amazon. the comparison took place primarily in six areas: search, presentation of results, enriched content, user participation, personalization, and web 2.0 technologies applied in opacs. the authors gave a detailed description of the research results supplemented by tables and snapshots of the catalogs in comparison. the findings indicated that “the progress of library catalogues has really been substantial in the last few years.” specifically, the library catalogues have made “the best progress on the content field and the least in user participation and personalization.” when compared to services offered by amazon, the authors concluded that “none of the six chosen catalogues offers the complete package of examined options that amazon does.”8 in other words, library catalogs in the sample still lacked features compared to amazon. the other comparative study was conducted by linda riewe, a library school student, in fulfillment for her master’s degree from san jose university. the research described in her thesis is a questionnaire survey targeted at 361 libraries that compares open-source (specifically, koha and evergreen) and propriety ilss in north america. more than twenty proprietary systems were covered, including horizon, voyager, millennium, polaris, innopac, and unicorn.9 only a small part of her study was related to opacs. it involved three questions about opacs and asked librarians to evaluate the ease of use of their ils opac’s search engines, their opac search engine’s completeness of features, and their perception of how easy it is for patrons to make self-service requests online for renewals and holds. a scale of 1 to 5 was used (1 = least satisfied; 5= very satisfied) regarding the three aspects of opacs. the mean and medium satisfaction ratings for open-source opacs were higher than those of proprietary ones. koha’s opac was ranked 4.3, 3.9, and 3.9, respectively in mean, the highest on the scale in all three categories, while the proprietary opacs were ranked 3.9, 3.6, and 3.6.10 evergreen fell in the middle, still ahead of proprietary opacs. the findings reinforced the perception that open-source catalogs, especially koha, offer more advanced features than proprietary ones. as riewe’s study focused more on the cost and user satisfaction with ilss, it yielded limited information about the connected opacs. no comparative research has measured the progress of open-source versus proprietary catalogs toward the next-generation library catalog. therefore the comparison described in this paper is the first of its kind. as only koha, everygreen, and voyager’s opacs are examined in this paper, the results cannot be extrapolated. studies on a larger scale are needed to shed light on the progress librarians have made toward the next-generation catalog. ■■ method the first step of the study was identifing and defining of a set of measurements by which to compare the three opacs. a review of library literature on the next-generation library catalog revealed different and somewhat conflicting points of views as to what the nextgeneration catalog should be. as marshall breeding put it, “there isn’t one single answer. we will see a number of approaches, each attacking the problem somewhat differently.”11 this study decided to use the most commonly held visions, which are summarized well by breeding and by morgan’s lita executive summary.12 the ten parameters identified and used in the comparison were taken primarily from breeding’s introduction to the july/ august 2007 issue of library technology reports, “nextgeneration library catalogs.”13 the ten features reflect some librarians’ visions for a modern catalog. they serve as additions to, rather than replacements of, the feature sets commonly found in legacy catalogs. the following are the definitions of each measurement: ■■ a single point of entry to all library information: “information” refers to all library resources. the next-generation catalog contains not only bibliographical information about printed books, video tapes, and journal titles but also leads to the full text of all electronic databases, digital archives, and any other library resources. it is a federated search engine for one-stop searching. it not only allows for one search leading to a federation of results, it also links to full-text electronic books and journal articles and directs users to printed materials. ■■ state-of-the-art web interface: library catalogs should be “intuitive interfaces” and “visually appealing sites” that compare well with other internet search engines.14 a library’s opac can be intimidating and complex. to attract users, the next-generation catalog looks and feels similar to google, amazon, and other popular websites. this criterion is highly subjective, however, because some users may find google and amazon anything but intuitive or appealing. the underlying assumption is that some internet search engines are popular, and a library catalog should be similar to be popular themselves. ■■ enriched content: breeding writes, “legacy catalogs tend to offer text-only displays, drawing only on the marc record. a next-generation catalog might bring in content from different sources to strengthen the visual appeal and increase the amount of information presented to the user.”15 the enriched content the next generation library catalog | yang and hofmann 143 includes images of book covers, cd and movie cases, tables of contents, summaries, reviews, and photos of items that traditionally are not present in legacy catalogs. ■■ faceted navigation: faceted navigation allows users to narrow their search results by facets. the types of facets may include subjects, authors, dates, types of materials, locations, series, and more. many discovery tools and federated search engines, such as villanova university’s vufind and innovative interface’s encore, have used this technology in searches.16 auto-graphics also applied this feature in their opac, agent iluminar.17 ■■ simple keyword search box: the next-generation catalog looks and feels like popular internet search engines. the best example is google’s simple user interface. that means that a simple keyword search box, instead of a controlled vocabulary or specific-field search box, should be presented to the user on the opening page with a link to an advanced search for user in need of more complex searching options. ■■ relevancy: traditional ranking of search results is based on the frequency and positions of terms in bibliographical records during keyword searches. relevancy has not worked well in opacs. in addition, popularity is another factor that has not been taken into consideration in relevancy ranking. for instance, “when ranking results from the library’s book collection, the number of times that an item has been checked out could be considered an indicator of popularity.”18 by the same token, the size and font of tags in a tag cloud or the number of comments users attach to an item may also be considered relevant in ranking search results. so far, almost no opacs are capable of incorporating circulation statistics into relevancy ranking. ■■ “did you mean . . . ?”: when a search term is not spelled correctly or nothing is found in the opac in a keyword search, the spell checker will kick in and suggest the correct spelling or recommend a term that may match the user’s intended search term. for example, a modern catalog may generate a statement such as “did you mean . . . ?” or “maybe you meant . . . .” this may be a very popular and useful service in modern opacs. ■■ recommendations and related materials: the nextgeneration catalog is envisioned as promoting reading and learning by making recommendations of additional related materials to patrons. this feature is an imitation of amazon and websites that promote selling by stating “customers who bought this item also bought . . . .” likewise, after a search in the opac, a statement such as “patrons who borrowed this book also borrowed the following books . . .” may appear. ■■ user contribution—ratings, reviews, comments, and tagging: legacy catalogs only allow catalogers to add content. in the next-generation catalog, users can be active contributors to the content of the opac. they can rate, write reviews, tag, and comment on items. user contribution is an important indicator for use and can be used in relevancy ranking. ■■ rss feeds: the next-generation catalog is dynamic because it delivers lists of new acquisitions and search updates to users through rss feeds. modern catalogs are service-oriented; they do more than provide a simple display search results. the second step is to apply these ten visions to the opacs of koha, evergreen, and webvoyage to determine if they are present or absent. the opacs used in this study included three examples from each system. they may have been product demos and live catalogs randomly chosen from the user list on the product websites. the latest releases at the time of the study was koha 3.0, evergreen 2.0, webvoyage 7.1. in case of discrepancies between product descriptions and reality, we gave precedence to reality over claims. in other words, even if the product documentation lists and describes a feature, this study does not include it if the feature is not in action either in the demo or live catalogs. despite the fact that a planned future release of one of those investigated opacs may add a feature, this study only recorded what existed at the time of the comparison. the following are the opacs examined in this paper. koha ■■ koho demo for academic libraries: http://academic .demo.kohalibrary.com/ ■■ wagner college: http://wagner.waldo.kohalibrary .com/ ■■ clearwater christian college: http://ccc.kohalibrary

.edu/vwebv/searchbasic 144 information technology and libraries | september 2010 ■■ shoreline college library: http://shoreline.library .ctc.edu/vwebv/searchbasic the final step includes data collection and compilation. a discussion of findings follows. the study draws conclusions about which opac is more advanced and has more features of the next-generation library catalog. ■■ findings each of the opacs of koha, evergreen, and webvoyage are examined for the presence of the ten features of the next-generation catalog. single point of entry for all library information none of the opacs of the three ilss provides true federated searching. to varying degrees, each is limited in access, showing an absence of contents from electronic databases, digital archives, and other sources that generally are not located in the legacy catalog. of the three, koha is more advanced. while webvoyage and evergreen only display journal-holdings information in their opacs, koha links journal titles from its catalog to proquest’s serials solutions, thus leading users to fulltext journals in the electronic databases. the example in figure 1 (koha demo) shows the journal title unix update with an active link to the full-text journal in the availability field. the link takes patrons to serials solutions, where full text at the journal-title level is listed for each database (see figure 2). each link will take you into the full text in each database. state-of-the-art web interface as beauty is in the eye of the beholder, the interface of a catalog can be appealing to one user but prohibitive to another. with this limitation in mind, the out-of-thebox user interface at the demo sites was considered for each opac. all the three catalogs have the google-like simplicity in presentation. all of the user interfaces are highly customizable. it largely depends on the library to make the user interface appealing and welcoming to users. figures 3–5 show snapshots from each ilss demo sites and have not been customized. however, there are a few differences in the “state of the art.” for one, koha’s navigation between screens relies solely on the browser’s forward and back buttons, while webvoyage and evergreen have internal navigation buttons that more efficiently take the user between title lists, headings lists, and record displays, and between records in a result set. while all three opacs offer an advanced search page with multiple boxes for entering search terms, only webvoyage makes the relationship between the terms in different boxes clear. by the use of a drop-down box, it makes explicit that the search terms are by default anded and also allows for the selection of or and not. in koha’s and evergreen’s advanced search, however, the terms are anded only, a fact that is not at all obvious to the user. in the demo opacs examined, there is no option to choose or or not between rows, nor is there any indication that the search is anded. the point of providing multiple search boxes is to guide users in constructing a boolean search without their having to worry about operators and syntax. in koha, however, users have to type an or or not statement themselves within the text box, thus defeating the purpose of having multiple boxes. while evergreen allows for a not construction within a row (“does not contain”), it does not provide an option for or (“contains” and “matches exactly” are the other two options available). see figures figure 1. link to full-text journals in serials solutions in koha figure 2. links to serials solutions from koha the next generation library catalog | yang and hofmann 145 6–8. thus koha’s and evergreen’s advanced search is less than intuitive for users and certainly less functional than webvoyage’s. enriched content to varying degrees, enriched content is present in all three catalogs, with koha providing the most. while all three catalogs have book covers and movie-container art, koha has much more in its catalog. for instance, it displays tags, descriptions, comments, and amazon reviews. webvoyage displays links to google books for book reviews and content summaries but does not have tags, descriptions, and comments in the catalog. see figures 9–11. faceted navigation the koha opac is the only catalog of the three to offer faceted navigation. the “refine your search” feature allows users to narrow search results by availability, places, libraries, authors, topics, and series. clicking on a term within a facet adds that term to the search query and generates a narrower list of results. the user may then choose another facet to further refine the search. while evergreen appears to have faceted navigation upon first glance, it actually does not possess this feature. the following facets appear after a search generates hits: “relevant subjects,” “relevant authors,” and “relevant series.” but choosing a term within a facet does not narrow down the previous search. instead, it generates an entirely new search with the selected term; it does not add the new term to the previous query. users must manually combine the terms in the simple search box or through the advanced search page. webvoyage also does not offer faceted navigation—it only provides an option to “filter your search” by format, language, and date when a set of results is returned. see figures 12–14. keyword searching koha, evergreen, and webvoyage all present a simple keyword search box with a link to the advanced search (see figures 3–5). relevancy neither koha, evergreen, nor webvoyage provide any evidence for meeting the criteria of the next-generation catalog’s more inclusive vision of relevancy ranking, such as accounting for an item’s popularity or allowing user tags. koha uses index data’s zebra program for its relevance ranking, which “reads structured records in a variety of input formats . . . and allows access to them through exact boolean search figure 3. koha: state-of-the-art user interface figure 5. voyager: state-of-the-art user interface figure 4. evergreen: state-of-the-art user interface 146 information technology and libraries | september 2010 user contributions koha is the only system of the three that allows users to add tags, comments, descriptions, and reviews. in koha’s opac, user-added tags form tag clouds, and the font and size of each keyword or tag indicate that keyword or figure 6. voyager advanced search figure 7. koha advanced search figure 8. evergreen advanced search expressions and relevance-ranked free-text queries.19 evergreen’s dokuwiki states that the base relevancy score is determined by the cover density of the searched terms. after this base score is determined, items may receive score bumps based on word order, matching on the first word, and exact matches depending on the type of search performed.20 these statements do not indicate that either koha or evergreen go beyond the traditional relevancy-ranking methods of legacy systems, such as webvoyage. did you mean . . . ? only evergreen has a true “did you mean . . . ?” feature. when no hits are returned, evergreen provides a suggested alternate spelling (“maybe you meant . . . ?”) as well as a suggested additional search (“you may also like to try these related searches . . .”). koha has a spell-check feature, but it automatically normalizes the search term and does not give the option of choosing different one. this is not the same as a “did you mean . . . ?” feature as defined above. while the normalizing process may be seamless, it takes the power of choice away from the user and may be problematic if a particular alternative spelling or misspelling is searched purposefully, such as “womyn.” (when “womyn” is searched as a keyword in the koha demo opac, 16,230 hits are returned. this catalog does not appear to contain the term as spelled, which is why it is normalized to women. the fact that the term does not appear as is may not be transparent to the searcher.) with normalization, the user may also be unaware that any mistake in spelling has occurred, and the number of hits may differ between the correct spelling and the normalized spelling, potentially affecting discovery. the normalization feature also only works with particular combinations of misspellings, where letter order affects whether a match is found. otherwise the system returns a “no result found!” message with no suggestions offered. (try “homoexuality” vs. “homoexsuality.” in koha’s demo opac, the former, with a missing “s,” yields 553 hits, while the latter, with a misplaced “s,” yields none.) however, koha is a step ahead of webvoyage, which has no built-in spell checker at all. if a search fails, the system returns the message “search resulted in no hits.” see figures 15–17. recommendations/related materials none of the three online catalogs can recommend materials for users. the next generation library catalog | yang and hofmann 147 figure 9. koha enriched content figure 10. evergreen enriched content figure 11. voyager enriched content figure 12. koha faceted navigation figure 13. evergreen faceted navigation figure 14. voyager faceted navigation 148 information technology and libraries | september 2010 nevertheless, the user contribution in the koha opac is not easy to use. it may take many clicks before a user can figure out how to add or edit text. it requires user login, and the system cannot keep track of the search hits after a login takes place. therefore the user contribution features of koha need improvement. see figure 18. rss feeds koha provides rss feeds, while evergreen and webvoyage do not. ■■ conclusion table 1 is a summary of the comparisons in this paper. these comparisons show that the koha opac has six out of the ten compared features for the next-generation catalog, plus two halves. its full-fledged features include state-of-the-art web interface, enriched content, faceted navigation, a simple keyword search box, user contribution, and rss feeds. the two halves indicate the existence of a feature that is not fully developed. for instance, “did you mean . . . ?” in koha does not work the way the next-generation catalog is envisioned. in addition, koha has the capability of linking journal titles to full text via serials solutions, while the other two opacs only display holdings information. evergreen falls into second place, providing four out of the ten compared features: state-of-the-art interface, enriched content, a keyword search box, and “did you mean . . . ?” webvoyage, the voyager opac from ex libris, comes in third, providing only three out of the ten features for figure 15. evergreen: did you mean . . . ? figure 16. koha: did you mean . . . ? figure 17. voyager: did you mean . . . ? figure 18. koha user contibutions tag’s frequency of use. all the tags in a tag cloud serve as hyperlinks to library materials. users can write their own reviews to complement the amazon reviews. all user-added reviews, descriptions, and comments have to be approved by a librarian before they are finalized for display in the opac. the next generation library catalog | yang and hofmann 149 the next-generation catalog. based on the evidence, koha’s opac is more advanced and innovative than evergreen’s or voyager’s. among the three catalogs, the open-source opacs compare more favorably to the ideal next-generation catalog then the proprietary opac. however, none of them is capable of federated searching. only koha offers faceted navigation. webvoyage does not even provide a spell checker. the ils opac still has a long way to go toward the nextgeneration catalog. though this study samples only three catalogs, hopefully the findings will provide a glimpse of the current state of open-source versus proprietary catalogs. ils opacs are not comparable in features and functions to stand-alone opacs, also referred to as “discovery tools” or “layers.” some discovery tools, such as ex libris’ primo, also are federated search engines and are modeled after the next-generation catalog. recently they have become increasingly popular because they are bolder and more innovative than ils opacs. two of the best stand-alone open-source opacs are villanova university’s vufind and oregon state university’s libraryfind.21 both boast eight out of ten features of the next-generation catalog.22 technically it is easier to develop a new stand-alone opac with all the next-generation catalog features than mending old ils opacs. as more and more libraries are disappointed with their ils opacs, more discovery tools will be implemented. vendors will stop improving ils opacs and concentrate on developing better discovery tools. the fact that ils opacs are falling behind current trends may eventually bear no significance for libraries—at least for the ones that can afford the purchase or implementation of a more sophisticated discovery tool or stand-alone opac. certainly small and public libraries who cannot afford a discovery tool or a programmer for an open-source opac overlay will suffer, unless market conditions change. references 1. tanja mercun and maja žumer, “new generation of catalogues for the new

president frederick kilgour at 4:45 p.m. the following were present: board-frederick g. kilgour, lawrence w. s. auld, paul j. fasana, susan k. martin, ralph m. shoffner, donald p. hammer ( isad

it was moved by susan martin that the isad board establish a policy that only material produced by ala units or related professional organizations be included in its disseminations or displays. seconded by paul fasana. carried. video/cable section. mr. roberto esteves, chairman of the ala video/ cable ad hoc study committee, solicited the interest of and activity by the isad board in getting video i cable incorporated into the isad structure. he reported that his committee had considered three alternatives as to where video/ cable concerns could be situated within ala: ( 1) it could remain as a task force in srrt; (2) a separate round table on video/ 216 i ouj'nal of libmry automation vol. 7 i 3 september 197 4 that had been before the evaluation, when it was his belief that isa was a cunent awareness service. mr. fasana recommended that the executive secretary write isa a letter informing them that the board cannot consider becoming a sponsor at this time. asidic. mr. hammer informed the board that peter watson had talked with him about asidic liaison, and they had concluded that asidic is primarily interested in having an observer at isad board meetings. to accomplish this requires no action from the board. wednesday, july 10, 1974 the meeting was called to order at 4:40 p.m. by president frederick kilgour. those present were: board-frederick g. kilgour, lawrence w. s. auld, paul j. fasana, susan k. martin, ralph m. shoffner, donald p. hammer (isad executive secretary), and berniece coulter, secretary, isad. committee chairmen-brian aveney, brett butler, helen schmierer, velma veneziano. guests-henriette d. avram, gerald lazorick, ruth l. tighe. sdi service for ala members. mr. lazorick (ohio state university mechanized information center) discussed the advantages to ala members if the osu selective dissemination of information service were available to them by subscription. the center would charge $50 per year for a profile, as opposed to the standard $300. the contract for sdi and retrospective searches (two services) would require ala to guarantee $17,000 per year ( $10,000 for sdi and $7,000 for retrospective searches). also, mr. fasana estimated that advertising and publicity costs might be as much as $5,000. mr. lazorick further explained that the printing of the necessary materials and the mailing would be handled by the center. ala would be responsible for advertising, marketing, and billing. it was relayed to the board that mr. wedgeworth did not feel that ala would profit enough for the amount it would have to pay for the service. he felt that osu could provide the service directly to individuals without the intervention of ala. mr. kilgour said that he felt a need to know that the money paid would indeed return to ala. the board had in the past expressed an interest in this type of service for ala members, and mr. kilgour asked if this feeling still existed. there was agreement among the board that it would be a desirable service for ala members. mr. kilgour stated that it will be necessary to: ( 1) determine the actual costs; ( 2) find the least expensive way of informing the members of this opportunity; and ( 3) obtain a commitment from the membership. he further said he would talk with mr. wedgeworth to see if agreement could highlights of meetings 215 cable could be formed; or ( 3) a section on video i cable could be formed in isad. the committee had favored an isad section. a round table might have more appeal to members, but would be outside the ala divisional and political structure. he further made known the desire of the committee for coordination of the forty-nine existing groups involved with audiovisual in ala. he noted that it would be possible to create a committee on a v within the isad section on video/ cable if there were interest in that approach to solving the problem. motion. mr. fasana moved that the isad board endorse in principle the ala video/cable ad hoc study committee's suggestion to create within isad a section devoted to video/ cable. seconded by susan martin. carried. misleading claims. mr. salmon indicated that some advertising over the last few years had appeared to be misleading, and that in some cases librarians' and libraries' names had been incorporated into advertising literature without their knowledge. two rtsd committees touch upon these problems as they relate to technical processing products and services: the bookdealer-library relations committee and the micropublishing projects committee. with adequate care, mr. salmon suggested, such a committee could be used by isad to ensure that its members are adequately informed. isad board members indicated an interest in and a need for a service of this nature, but reflected a hesitancy regarding the sensitivity of the issue. mr. kilgour asked that the matter be deferred until the wednesday board meeting, after the function statements of the two rtsd committees had been distributed to the board. isad historian. mr. hammer reviewed the action of the board previously in deciding to eliminate the history committee and appoint a historian if ala were going to publish a history of the association for the 1976 centennial celebration. since it has since been determined that ala will not produce such a publication, isad has no need to appoint a historian. isa (infonnation science abstmcts). mr. kilgour felt that there were now two obvious avenues open to the board at this time: ( 1) to pursue the evaluation of isa, or ( 2) to drop it altogether. mr. fasana said he believed that if ala were a sponsor, isa would abstract more library literature. because chemical information journals are among their sponsors, they cover chemical literature heavily. he felt that isad should look seriously into isa sponsorship, as there is nothing comparable to it in the united states. the isa board is interested, he said, because it would increase' their subscriptions and also increase their scope if they obtained subscriptions from ala members. mr. hammer explained that isad at one time had attempted to organize a subscription campaign, but the response was poor. mr. kilgour said that his reaction had been in favor of sponsorship, but highlights of meetings 217 be reached after additional points were discussed. we could then determine the answers to the three questions mentioned above. bylaws and organization committee. the newly appointed chairman of the isad bylaws and organization committee, helen schmierer, explained that she had found two versions of the isad bylaws extant, and there was a question as to which was current. minutes of the division did not reveal that any actual vote by the membership concerning various changes in the bylaws ever took place. she suggested that her committee use the original ( 1968) version of the bylaws as the basis on which to present all subsequent changes to the membership for a vote. she told the board she would have a new version ready by midwinter, and that it could then be published in ]ola and voted on at the san francisco annual conference. in answer to a question from ms. schmierer, mr. kilgour explained that it was the intent of the board that the bylaws and organization committees be combined, and the resulting committee should provide guidelines for each new committee established subsequently within isad. he also stated that it was necessary that a change be made in the present bylaws so that if a president did not complete a term, there would be a special election in order to elect another vice-president to take over the following year. for other charges to the bylaws and organization committee, mr. kilgour referred ms. schmierer to the minutes of the 197 4 midwinter meeting. telecommunications committee report. mr. kilgour annouced that david waite had resigned as chairman of the telecommunications committee and that he had appointed philip long as new chairman. mr. long presented a report of the committee (exhibit 1). he said that the areas of interest of the committee were networking, protocol, and standards. the following resolution was passed at their meeting: "that ala, via isad, join the committee of corporate telephone users ( cctu) and thus support the effort to combat the at&t attempt to adversely modify the current w ats tariff; should it not be legally or financially feasible for isad i ala to join cctu the committee will nonetheless attempt to follow and rep01t on this and related regulatory items." mr. kilgour called for a motion recommending that ala become a member of the committee of corporate telephone users, an organization to combat the cunent revision of the w ats tariff, providing money is available and no legal problems are connected with ala's so doing. however, several members of the board wanted further information as to what would be the position of ala with regard to the organization and in what sense would that position be an advantage to the members of ala. copies of the document produced by the cctu were also requested. mr. long said 218 journal of libmry automation vol. 7/3 september 1974 that he would contact a member of that committee in new york and get copies to the board members. mr. long requested that his committee be enlarged. mr. kilgour told him to appoint as many members as he needed. program planning committee report. chairman brett butler reported on the new orleans institute on networking which he felt was very successful both topically and financially. he said smaller libraries are beginning to consider automation, and therefore are sending staff to these institutes. he reported that $9,300 was received from registration fees, and expenses were approximately $6,100. in addition, $1,800 in expenses were paid by slice. mr. hammer will send a report to the board. mr. butler told of the committee's meeting in may in chicago. the minutes of that meeting, written by mr. hammer, had been approved by the committee and could be distributed to the board. he further related that the program at the new york annual conference had gone well, with approximately 400 in attendance. there were no plans for publication of the proceedings of the program, although it had been taped for sale by ala. mr. butler said the program planning committee desired liaison with each isad operating committee. they had appointed someone to tesla and hoped to do likewise with the telecommunications committee. at the suggestion of ms. avram, a serials institute has been planned for atlanta in october, preceding the asis meeting. josh smith (asis) and mr. hammer are the coordinators. mr. butler also announced that another institute on networking would be held in the spring in new orleans. with more advance publicity he felt there would be a greater response than the institute of march 197 4, which had an attendance of over 125. the 1975 institute will be a basic tutorial; james rizzolo is responsible for the content. plans for a series of cooperative programs with asis were laid out by the committee. this had been discussed with josh smith and had received his approval. mr. butler said he would prepare a statement which would describe the fiscal organization to be sent to the board for a mail vote. mr. kilgour expressed his opinion that with the new dues structure, the board must look at the financial gain involved in the institutes. in fact, any money-making venture must be considered at this time due to the dues structure change. plans for the cable tv preconference at san francisco ( 1975) were dropped. a program for san francisco would center around reactions to the document produced by the national commission on libraries and information science, the final draft of which is to be published in january 1975. this program is to be analytical in nature. mr. butler explained that there is possible cosponsorship interest. also at the san francisco annual conference, the office of intellectual highlights of meetings 219 freedom will cosponsor with isad a panel on various aspects of privacy and data file security. mr. butler announced that fifteen deans of library schools had attended that morning's meeting of the committee. there is interest in cosponsorship of continuing education programs, but nothing has been made definite at this point. the committee will explore this further. committee on representation in machine readable form of bibliographic information (marbi) report. (exhibit 2). velma veneziano requested that mr. fasana report to isad, as he had prepared a summary of the meeting for the rtsd board of directors. she asked mr. kilgour if the board would approve her writing the canadian library association to grant permission to send an official observer to marbi, as requested. mr. kilgour suggested that the letter definitely state that this representative would be a nonvoting participant. cola. (exhibit 3 ). thursday, july 11, 1974 the meeting was called to order by president frederick kilgour at 4:30p.m. those present were: board-frederick g. kilgour, lawrence w. s. auld, paul p. fasana, susan k. martin, ralph m. shoffner, donald p. hammer ( isad executive secretary), and berniece coulter, secretary, isad. guests-henriette d. avram, william summers. report of lola editor. copies of the ]ola annual report were distributed to the board (exhibit 4). ms. martin requested board reaction to changes suggested by the isad editorial board: ( 1) incorporate the issn on the cover of the journal, and drop the coden; (2) change the color of the cover of lola for each volume, beginning with the march 1975 issue; and ( 3) consider changing the title of the journal, in the light of possible incorporation of information technologies into isad, to the journal of library technology (jolt). the consensus of the board was that: ( 1) coden should remain on the cover; ( 2) a change in cover stock was quite appropriate; and (3) ]ola is a long-established title, and should remain. committee reports. mr. kilgour suggested that committee reports to the board be discontinued to save time and that written reports be submitted in the future. motion. it was moved by ralph shoffner that all isad committee reports be submitted to the board in writing and that the chairman appear before the board only if the committee desired some board action, and that the board has previously received this request in writing. seconded by larry auld. carried. mr. kilgour suggested that committee appointments be sent to the board by carbon copies of letters rather than reported as an agenda item. 220 ]oumal of library automation vol. 7/3 september 1974 representative to ansi x-4. motion. it was moved by ralph shoffner that mr. hammer explore and obtain, if possible, ala representation to ansi x-4 committee and that the board conditionally appoint arthur brody to be that representative. seconded by larry auld. carried. committee on technical standards for library automation (tesla) report. (exhibit 5). motion. it was moved by paul fasana to turn over to helen schmierer, chairman of the bylaws and organization committee, the matter of a revised charge to tesla. seconded by susan martin. carried. membership survey committee report. the final report of the membership survey ad hoc committee was distributed to the board members. this completed the work of the committee and the committee was therefore disbanded. mr. william summers, a member of the committee, appeared before the board. he stated that they had the computer capability to run any data correlations desired by the board. mr. kilgour asked the board members to request any correlations they would want from don hammer by october 15. he will forward them to ms. pope by mid-november, and she will have the correlations ready by the midwinter meeting in 1975. the board noted that the survey showed that 25 percent of !sad members are library directors, and that the most frequent age is over fifty. the number of people belonging to !sad who have no contact with library automation was surprising to some. a significant number of !sad members responded to the questionnaire. misleading claims. it was the sense of the board that the establishment of a committee in !sad to investigate misleading claims be referred to the bylaws and organization committee. the chairman is to contact william north, the ala attorney, concerning legal implications, and also steve salmon, who had shown interest in these problems, should be approached concerning the chairmanship. general discussion. most of the discussion centered around the new dues structure of the association. there was a question of how funds would be distributed to the divisions from institutional membership dues. ms. martin said that she would send the board an analysis of the expenditures and income for ]ola. the need for cash capital should be considered for the continuing publication of the journal despite advertising fluctuations. mr. shoffner stated that he favored using lola funds to sponsor !sad institutes and that there is a need for more introductory and elementary education in the !sad institutes. participants in the institutes had shown interest in basic knowledge of automation in order to make decisions in their work even though not necessarily involved directly with automation. highlights of meetings 221 exhibit 1 telecommunications committee report progress report of activities to date: 1. committee decided to maintain an awareness of future possibilities of two-way cable for data transmission, but not to continue active role in broadcast cable area in view of ongoing work in the area elsewhere. 2. committee members extensively debated the directions to which its future efforts would be actively directed; these included education, network protocol standards, etc. 3. committee accepted reports from messrs. randel and long on current suppliers of bibliographic services via star networking, and on current ansi and eia (plus iso) standards activities related to present and future bibliographic data transmission. 4. committee resolved: to attempt to formulate methods for computer-to-computer interaction (protocols) by telecommunication links, such that a single terminal of arbitrary characteristics could access a variety of host services in a "user-transparent" fashion. 5. various members of the committee accepted assignments in gathering data and protocols in use in such networks as arpa, tym-share, ncic, etc. it was recognized that the membership of the committee must be enlarged and that more than two ala meeting forums yearly are needed for the task. recommendations for division board action: the committee moved and unanimously passed a resolution that ala, via !sad, join the committee of corporate telephone users (cctu) and thus support the effort to combat the at&t attempt to adversely modify the current wats tariff; should it not be legally or financially feasible for !sad/ ala to join cctu the committee will nonetheless attempt to follow and report on this and related regulatory items. exhibit 2 committee on representation in machine readable form of bibliographic information (marbi) report following is a summary of deliberations and actions of the committee: 1. jola editorial, vol. 7, no. 2, 1974. the chairperson was asked to send a letter to the editor correcting the erroneous/ ambiguous reference to marbi and its relationship (formal and otherwise) to lc, clr cembi, etc. 2. conser. the committee took note of and discussed recent developments of the conser project. the committee will review and comment on formal recommendations of conser affecting marc serials format when they are submitted through lc. 3. clrjnsf sponsored conference on national bibliographic control. formal "conclusions and recommendations" of the conference have been distributed. the committee decided to take note of this document, ask each member to comment on the substance, and to prepare a formal critique/reaction of the conclusions for clr. 4. character sets. a progress report (by h. avram) was presented of international activities. extended character sets for latin (i.e., roman), cyrillic, and greek have been agreed to by iso working group on character sets. a draft standard i's being prepared. further work is being done on character sets for mathematical symbols and african languages. 5. iso 2709, format structure for marc records. progress report given. no action taken. 6. content designators. a progress report on international activities was given (by 222 i oumal of library automation vol. 7 i 3 september 197 4 h. avram) as well as a summary of some working papers prepared to date. copies will be submitted to the marbi members. 7. iso filing standards. a progress report was given. discussion but no action. 8. authority record formats. copies of the lc proposal for "authorities: a marc format" were distributed. a description of the work in progress at lc was given. lc tentatively plans to initiate a service for authorities in machine-readable form in 1975. the service probably will include names new to lc with cross-references and names new to marc with cross-references. 9. microform experiment. lc representative described a com microform experiment currently being defined/ set up at lc. the experiment will focus on lcsh 8th ed. in com format. 10. isbd-serials. the first formal publication of isbd-s was available at this conference. it was decided that each member would review the document and send comments to mr. fasana by august 15. mr. fasana was instructed to prepare a summary of the comments supplied. 11. catalog code revision committee. the need to establish liaison and input to this committee was discussed. arrangements were made with the chairperson of the ccrc (j. byrum) to establish input and liaison between the two committees. exhibit 3 cola discussion group report the isad cola discussion group met on july 7, 1974. brian aveney, chairman, mentioned that the subject of merger of cola with the marc users' discussion group had been informally raised, and invited comment from any members of the groups. discussion centered around the time needs and a suggestion was made that cola and mudg meet back to back. further discussion was deferred for later informal contacts. the program divided into two different sessions. the first consisted of a series of independent presentations on library automation activities around the counhy. those who reported were: helena rivoire (bucknell university); ron miller and bill mathews (nelinet); ann ekstrom (oclc); richard de gennaro (university of pennsylvania); james sokoloski (university of massachusetts); james dolby (r&d associates); howard harris (university of chicago); and stephen silberstein (university of california, berkeley). the second half of the program consisted of a panel presentation about the use of microform catalogs in libraries. richard jensen (university of texas, permian basin) described the use during the last year of a divided microfiche catalog produced under contract by richard abel co. no other form of access to the collection is provided for public use. a brief questionnaire about patron response indicated no great difficulties in use. some complaints about readers and filing were noted. mary fischer (los angeles public library) discussed the transition to com fiche for internal reports, for reasons of cost. a variety of reports can now be distributed to all branches which formerly did not have access to this information except at the central library. james rizzolo (new york public library) mentioned the dance collection catalog now available on film. user response has been very positive, but the fact that this is the first time any form of catalog has been available is probably a large factor in this response. a com marc character set has been developed with a new york vendor for use in internal fiche files, and samples were made available to the group. highlights of meetings 223 exhibit 4 journal of library automation annual report this report covers the eighteen months between january 1973 and june 1974. during this period nine issues of ]ola appeared, from the june 1972 to the june 1974 issues. these issues contained thirty-nine articles and twenty-three book reviews. in addition, lola/technical communications was incorporated into the journal with the march 1973 issue. with volume 7 (1974), an editorial or guest editorial appears in each issue. in january 1973 the journal was eight months behind. ala's central production unit was to have taken over the technical editing with the 1973 volume, but due to the unforeseen delay in publication the staff was not familiar with the journal, or the printer. by march all the major problems had been sorted out, and the june 1972 issue was sent to the printer. at that time there was a bacldog of thirty-five manuscripts, of which twenty were eventually published, nine were rejected, and six are still pending (either sent back to the author for revision, or still in the process of locating or identifying the author). with volume 6 (1973), the contract for printing was given to the ovid bell press, inc. spencer-walker did not bid on a contract renewal. because of the increasing cost of paper and the narrower selection offered by paper manufacturers, the editorial board determined that at the same time it would be reasonable to change from use of permalife to another cheaper but acid-free stock. warren old english was selected; at the time (june 1973) it was $25.10 per hundredweight. since february 1973, ]ola has received fifty manuscripts for consideration: published 18 rejected 11 accepted 7 in review 4 pending 9 sent to tc editor 1 it is difficult to summarize the content of these nine issues. when categorized very broadly, the thirty-nine articles covered the following topics: aspects of cataloging 7 search keys and file structure 7 national automation and standards 7 isad topics 5 circulation 5 acquisitions 2 serials 2 information reh·ieval 2 administration 1 other 1 don bosseau continues, i am pleased to say, as editor of technical communications. peter simmons (university of british columbia) accepted the position of book review editor, and is also doing an excellent job. he reports that, in addition to the reviews already published, eleven reviews have been submitted and are awaiting publication, and six books are in the hands of reviewers. the central production unit has been of invaluable assistance in bringing the journal up to date, in negotiating with the post office on our behalf, and in continuing to provide technical editing support. lola is now completely up to date; i hope that we shall continue to improve the 224 journal of libmry automation vol. 7/3 september 197 4 standards for acceptance of articles, and that time will now permit us to examine the journal critically to determine where improvements could or should be made. exhibit 5 committee on technical standards for library automation report

revised be approved by the isad board. 3. draft procedure. the tesla procedure for handling standards proposals was reviewed and the following changes recommended: a. proposal outline item viii be made optional. b. reactor ballot include three responses, e.g., for/ against-need for standard; for/against-specification of standard; yes/no-available to work on specification. these changes will be made and published in the next issue of jola-tc. 4. publication of materials relating to standards. the article describing the committee's procedures and role and outlining the standards organization potentially impacting libraries was published in jola. the committee discerned that standards exist which would be of importance to the library community and that these be identified and reviewed in terms of their impact on libraries. as a first step, a listing of those standards will be drawn up and, on review of the committee, published in jola-tc. 5. representative to ansi-x4. the ala is currently not represented on ansi-x4. the committee recommends that the isad board nominate mr. arthur brody as the ala representative to ansi-x4. 6. metrication. the current movement to metric

and laurie bridges information technology and libraries | december 2017 7 abstract this exploratory study examined the use of the oregon state university libraries website via mobile devices by advanced researchers at an off-campus branch location. branch campus–affiliated faculty, staff, and graduate students were invited to participate in a survey to determine what their research behaviors are via mobile devices, including frequency of their mobile library website use and the tasks they were attempting to complete. findings showed that while these advanced researchers do periodically use the library website via mobile devices, mobile devices are not the primary mode of searching for articles and books or for reading scholarly sources. mobile devices are most frequently used for viewing the library website when these advanced researchers are at home or in transit. results of this survey will be used to address knowledge gaps around library resources and research tools and to generate more ways to study advanced researchers’ use of library services via mobile devices. introduction as use of mobile devices has expanded in the academic environment, so has the practice of gathering data from multiple sources about what mobile resources are and are not being used. this data informs the design decisions and resource investments libraries make in mobile tools. web analytics is one tool that allows researchers to discover which devices patrons use to access library webpages. but web analytics data do not show what patrons want to do and what hurdles they face when using the library website via a mobile device. web analytics also lacks nuance in that it cannot distinguish user characteristics, such as whether users are novice or advanced researchers, which may affect how these users interact with a mobile device. user surveys are another tool for gathering data on mobile behaviors. user surveys help overcome some of the limitations of web analytics data by directly asking users about their perceived research skills and the resources they use on a mobile device. as is the case at most libraries, oregon state university libraries serves a diverse range of users. we were interested in learning whether advanced researchers—particularly advanced researchers who work at a branch campus—use the library’s resources differently than main mary j. markland (mary.markland@oregonstate.edu), is head, guin library; hannah gascho rempel (hannah.rempel@oregonstate.edu) is science librarian and coordinator of graduate student success services; and laurie bridges (laurie.bridges@oregonstate.edu) is instruction and outreach librarian, oregon state university libraries and press. mailto:mary.markland@oregonstate.edu mailto:hannah.rempel@oregonstate.edu mailto:laurie.bridges@oregonstate.edu mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 8 campus users. we were chiefly interested in these advanced researchers because of the mobile nature of their work. they are graduate students and faculty in the field of marine science who work in a variety of locations, including their offices, labs, and in the field (which can include rivers, lakes, and the ocean). we focused on the use of the library website via mobile devices as one way to determine whether specific library services should be adapted to best meet the needs of this targeted user community. oregon state university (osu) is oregon’s land-grant university; its home campus is in corvallis, oregon. hatfield marine science center (hmsc) in newport is a branch campus that includes a branch library. guin library at hmsc serves osu students and faculty from across the osu colleges along with the co-located federal and state agencies of the national oceanic and atmospheric administration (noaa), us fish and wildlife service, environmental protection agency (epa), united states geological survey (usgs), united states department of agriculture (usda), and the oregon department of fish and wildlife. the guin library is in newport, which is forty-five miles from the main campus. like many other branch libraries, guin library was established at a time when providing a print collection close to where researchers and students work was paramount, but today it must adapt its services to meet the changing information needs of its user base. branch libraries are typically designed to serve a clientele or subject area, which can create a different institutional culture from the main library. guin library serves advanced undergraduates, graduate students, and scientific researchers. hmsc’s distance from corvallis, the small size of the researcher community, and the shared focus on a research area—marine sciences—create a distinct culture. while guin library is often referred to as the “heart of hmsc,” the number of in-person library users is decreasing. this decline is not unexpected as numerous studies have shown that faculty and graduate students have fewer needs that require an in-person trip to the library.1 studies have also shown that faculty and graduate students can be unaware of the services and resources that libraries provide, thereby continuing the cycle of underuse. 2 to learn more about the needs of hmsc’s advanced researchers, this exploratory study examined their research behaviors via mobile devices. the goals of this study were to • determine if and with what frequency advanced researchers at hmsc use the osu libraries website via mobile devices; • gather a list of tasks advanced users attempt to accomplish when they visit the osu libraries website on a mobile device; and • determine whether the mobile behaviors of these advanced researchers are different from those of researchers from the main osu campus (including undergraduate students), and if so, whether these differences warrant alternative modes of design or service delivery. information technology and libraries | december 2017 9 literature review the conversation about how best to design mobile library websites has shifted over the past decade. early in the mobile-adoption process some libraries focused on creating special websites or apps that worked with mobile devices.3 while libraries globally might still be creating mobilespecific websites and apps,4 us libraries are trending toward responsively designed websites as a more user-friendly option and a simpler solution for most libraries with limited staff and budgets.5 most of the literature on mobile-device use in higher education is focused on undergraduates across a wide range of majors who are using a standard academic library. 6 to help provide context for how libraries have designed their websites for mobile users, some of those specific findings will be shared later. but because our study focused on graduate students and faculty in a sciencefocused branch library, we will begin with a discussion of what is known about more advanced researchers’ use of library services and their mobile-device habits. several themes emerged from the literature on graduate students’ relationships with libraries. in an ironic twist, faculty think graduate students are being assisted by the library while librarians think faculty are providing graduate students with the help they need to be successful.7 this results in many graduate students end up using their library’s resources in an entirely disintermediated way. graduate students, especially those in the sciences, visit the physical library less often and use online resources more than undergraduate students.8 most graduate students start their research process with assistance from academic staff, such as advisors and committee members,9 and are unaware of many library services and resources.10 as frequent virtual-library users who receive little guidance on how to use the library’s tools, graduate students need a library website that is clear in scope and purpose, offers help, and has targeted services. 11 compared to reports on undergraduate use of mobile devices to access their library’s website, relatively few studies have focused on graduate-student or faculty mobile behaviors. a recent survey of japanese library and information science (lis) students compared and undergraduate graduate students’ usage of mobile devices to access library services and found slight differences. however, both groups reported accessing libraries as last on their list of preferred smartphone uses.12 aharony examined the mobile use behaviors of israeli lis graduate students and found approximately half of these graduate students used smartphones and perceived them to be useful and easy tools for use in their everyday life, and could transfer those habits to library searching behaviors.13 when looking specifically at how patrons use library services via a mobile device, rempel and bridges found the top reason graduate students at their main campus used the osu libraries website via mobile devices was to find information on library hours, followed by finding a book and researching a topic.14 barnett-ellis and vann surveyed their small university and found that both undergraduate and graduate students were more than twice as likely to use mobile devices as are their faculty and staff; a majority of students also indicated they were likely to use mobile devices to conduct research.15 finally, survey results showed graduate students in hofstra university’s college of education reported accessing library materials via a mobile device twice as often as other student groups. in addition, these graduate students reported being comfortabl e mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 10 reading articles up to five pages long on their mobile devices. graduate students were also more likely to be at home when using their mobile device to access the library, a finding the authors attributed to education graduate students frequently being employed as full-time teachers.16 research on how faculty members use library resources characterizes a population that is confident in their literature-searching skills, prefers to search on their own, and has little direct contact with the library.17 faculty researchers highly value convenience;18 they rely primarily on electronic access to journal articles but prefer print access to monographs.19 faculty tend to be self-trained at using search tools, such as pubmed or other online databases, and therefore are not always aware of the more in-depth functionality of these tools.20 in contrast to graduate students, rempel and bridges found that faculty using the library website via mobile devices were less interested in information about the physical library, such as library hours, and were more likely to be researching a topic.21 medical faculty are one of the few faculty groups whose mobile-research behaviors have been specifically examined. a survey administered by bushhousen et al. at a medical university revealed that a third of respondents used mobile apps for research-related activities.22 findings by boruff and storie indicate that one of the biggest barriers to mobile use in health-related academic settings was wireless access.23 thus apps that did not require the user to be connected to the internet were highly desired. faculty and graduate students in health-related academic settings saw a role for the library in advocating for better wireless infrastructure, providing access to a targeted set of heavily used resources, and providing online guides or in-person tutorials on mobile apps or procedures specific to their institution. 24 according to the literature, most design decisions for library mobile sites have been made on the basis of information collected about undergraduate students’ behavior at main-branch campuses. to help inform our understanding of how recent decisions have been made, the remainder of the literature review focuses on what is known about undergraduate students’ mobile behavior. undergraduate students are very comfortable using mobile technologies and perceive themselves to be skilled with these devices. according to the 2015 educause center for research and analysis’ (ecar) study of undergraduate students and information technology, most undergraduate students consider themselves sophisticated technology users who are engaged with information technologies.25 undergraduate students mainly use their smartphones for nonclass activities. but students indicate they could be more effective technology users if they were more skilled at tools such as the learning management system, online collaboration tools, e-books, or laptops and smartphones in class. of interest to libraries is the ecar participants’ top area of reported interest, “search tools to find reference or other information online for class work.”26 however, when a mobile library site is in place, usage rates have been found to be lower than anticipated. in a study of undergraduate science students, salisbury et al. found only 2 percent of respondents reported using their cell phones to access library databases or the library’s catalog every hour or daily, despite 66 percent of the students browsing the internet using their mobile information technology and libraries | december 2017 11 phone hourly or daily. salisbury et al. speculated that users need to be told about mobileoptimized library resources if libraries want to increase usage. 27 rempel and bridges used a pop-up interrupt survey while users were accessing the osu libraries mobile site.28 this approach allowed a larger cross-section of library users to be surveyed. it also reduced memory errors by capturing their activities in real time. activities that had been included in the mobile site because of their perceived usefulness in a mobile environment, such as directions, asking a librarian a question, and the coffee shop webcam, were rarely cited as a reason for visiting the mobile site. the osu libraries branch at hmsc is entering a new era. a marine studies initiative will result in the building of a new multidisciplinary research campus at hmsc that aims to serve five hundred undergraduate students. the change in demographics and the increase in students who will need to be served has prompted guin library staff to explore how the current population of advanced researchers interact with library resources. in addition, examining the ways undergraduate students at the main campus use these tools will help with planning for the upcoming changes in the user community. methods this study used an online qualtrics survey to gather information about how frequently advanced researchers (graduate students, faculty, and affiliated scientists at a branch library for marine science) use the osu libraries website via mobile devices, what they search for, and other ways they use mobile devices to support their research behaviors. a recruitment email with a link to the survey was sent to three discussion lists used by hmsc community in spring 2016. the survey was available for four weeks, and a reminder email was sent one week before the survey closed. the invitation email included a link to an informedconsent document. once the consent document had been reviewed, users were taken to the survey via a second link. respondents could provide an email address to receive a three-dollar coffee card for participating in the study, but their email address was recorded in a separate survey location to preserve their anonymity. the invitation email indicated that this survey was about using the website via a mobile device, and the first survey question asked users if they had ever accessed the library website on a mobile device. if they answered “no,” they were immediately taken to the end of the survey and were not recorded as a participant in the study. a similar survey was conducted with users from osu’s main campus in 2012–13 and again in 2015. the results from 2012–13 have been published previously,29 but the results from 2015 have not. while the focus of the present study is on the mobile behaviors of advanced researchers in the hmsc community, data from the 2015 main-campus study is used to provide a comparison to the broader osu community. osu main-campus respondents in 2015 and hmsc participants in 2016 both answered closedand open-ended questions that explored participants’ general mobiledevice behaviors and behaviors specific to using the osu libraries website via mobile devices. mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 12 however, the hmsc survey also asked questions about behaviors related to using the osu (nonlibrary) website via a mobile device and participants’ mobile scholarly reading and writing behaviors. the survey concluded with several demographic questions. the survey data was analyzed using qualtrics’ cross-tab functionality and microsoft excel to observe trends and potential differences between user groups. open-ended responses were examined for common themes. twenty-three members of the hmsc community completed the survey, whereas one hundred participants responded to the 2015 main campus survey. participation in the 2015 survey was capped at one hundred respondents because limited incentives were available. the participation difference between the two surveys reflects several differences between the two sampled communities. the most obvious difference is size. the osu community comprises more than thirty-six thousand students, faculty, and staff; the hmsc community is approximately five hundred students, researchers, and faculty—some of whom are also included as part of the larger osu community. the second factor influencing response rates relates to the difference in size between the two communities, but is more striking in the hmsc community: the survey relied on a self-selected group of users who indicated they had a history using the library website via a mobile device. therefore, it is not possible to estimate the population size of mobile-device library-website users specific to the branch library or the main campus library. this limitation means that the results from this study cannot be used to generalize findings to all users who visit a library website via mobile devices; instead the results are intended to present a case that other libraries may compare with behaviors observed on their own campuses. sharing the behaviors of advanced researchers at a branch campus is particularly valuable as this population has historically been understudied. results and discussion participant demographics and devices used of the twenty-three respondents to the hmsc mobile behaviors survey, 13 (62 percent) were graduate students, 7 (34 percent) were faculty (this category includes faculty researchers and courtesy faculty), and one respondent was an noaa employee. two participants declined to declare their affiliation. of the 97 respondents to the 2015 osu main-campus survey who shared their affiliation, 16 (16 percent) were graduate students, 5 (5 percent) were faculty members, and 69 (71 percent) were undergraduates. respondents varied in the types of mobile devices they used when doing library research. smartphones were used by 78 percent (18 respondents) and 22 percent (5 respondents) used a tablet. apple (15 respondents) was the most common device brand used, although six of the respondents used an android phone or tablet. compared to the general population’s device ownership, these respondents are more likely to own apple devices, but the two major device types owned (apple and android) match market trends.30 information technology and libraries | december 2017 13 frequency of library site use on mobile devices most of the hmsc respondents are infrequent users of the library website via mobile devices: 50 percent (11 respondents) did so less than once a month; 41 percent (9 respondents) did so at least once a month; and 9 percent (2 respondents) did so at least once a week. the low level of library website usage via mobile devices was especially notable as this population reports being heavy users of the library website via laptops or desktop computers, with 82 percent (18 respondents) visiting the library website via those tools at least once a week. researchers at hmsc used the library website via mobile devices much less often than the 2015 main-campus respondents (undergraduates, graduate students, and faculty). no hmsc respondents visited the mobile site daily compared to 10 percent of main-campus users, and only 9 percent of hmsc respondents visited weekly compared to 28 percent of main-campus users (see figure 1). figure 1. 2016 hmsc participants vs. 2015 osu main-campus participants reported frequency of library website visits via a mobile device by percent of responses. while hmsc advanced researchers share some mobile behaviors with main-campus students, this exploratory study demonstrates they do not use the library website via mobile devices as frequently. some possible reasons for this are researchers rarely spend time coming and going to and from classes and therefore do not have small gaps of time to fill throughout their day. instead, their daily schedule involves being in the field or in the lab collecting and analyzing data. 0% 10% 20% 30% 40% 50% 60% this is my first time less often than once a month at least once a month at least once a week every day or almost every day branch 2016 main 2015 mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 14 alternatively, they are frequently involved in writing-intensive projects such as drafting journal articles or grant proposals. they carve out specific periods to do research and do not appear to be filling time with short bursts of literature searching. they can work on laptops and do not need to multitask on a phone or tablet between classes or in other situations. mobile-device ownership among hmsc graduate students might also be limited because of personal budgets that do not allow for owning multiple mobile devices or for having the most recent model. in addition, this group of scientists may not be on the front edge of personal technologies, especially compared to medical researchers, because few mobile apps are designed specifically for the research needs of marine scientists. where researchers are when using mobile devices for library tasks because mobile devices facilitate connecting to resources from many locations, and because advanced researchers conduct research in a range of settings—including the field, the office, and home—we asked respondents where they were most likely to use the library website via a mobile device. thirty-two percent were most likely to be at home, 27 percent in transit; 18 percent at work; and 9 percent in the field. the popularity of using the library website via mobile devices while in transit was somewhat unexpected, but perhaps should not have been because many people try to maximize their travel time by multitasking on mobile devices. the distance from the main campus might explain this finding because a local bus service provides an easy way to travel to and from the main campus, and the hour-long trip would provide opportunities for multitasking via a mobile device. relatively few respondents used mobile devices to access the library website while at work. previous studies show that a lack of reliable campus wireless internet access can affect students’ ability to use mobile technology.31 hmsc also struggles to provide consistent wireless access, and signals are spotty in many areas of our campus. despite signal boosters in guin library, wireless access is still limited at times. in addition, cell phone service is equally spotty both at hmsc and up and down the coast of oregon. it is much less frustrating to work on a device that has a wired connection to the internet while at hmsc. these respondents did use mobile devices while at home, which might indicate they had a better wireless signal there. alternatively, working from home on a mobile device might indicate that they compartmentalize their library-research time as an activity to do at home instead of in the office. researchers used their mobile devices to access the library while in the field less than originally expected, but upon further reflection, it made sense that researchers would be less likely to use library resources during periods of data collection for oceanic or other water-based research projects because of their focused involvement during that stage. the water-based research also increases the risk of losing mobile devices. library resources accessed via mobile devices information technology and libraries | december 2017 15 to learn more about how these respondents used the library website, we asked them to choose what they were searching for from a list of options. respondents could choose as many options as applied to their searching behaviors. hmsc respondents’ primary reason for visiting the library’s site via a mobile device was to find a specific source: 68 percent looked for an article, 45 percent for a journal, 36 percent for a book, and 14 percent for a thesis. many of the hmsc respondents also looked for procedural or library-specific information: 36 percent looked for hours, 32 percent for my account information, 18 percent for interlibrary loan, 14 percent for contact information, 9 percent for how to borrow and request books, 9 percent for workshop information, and 9 percent for oregon estuaries bibliographies—a unique resource provided by the hmsc library. fifty-five percent of searches were for a specific source and 43 percent were for procedural or libraryspecific information. notably missing from this list were respondents who reported searching via their mobile device for directions to the library. compared to the 2015 osu libraries main-campus survey respondents, hmsc respondents were much more likely to visit the library website via a mobile device to look for an article (68 percent vs. 37 percent), find a journal (45 percent vs. 23 percent), access my account information (32 percent vs. 7 percent), use interlibrary loan (18 percent vs. 5 percent), or find contact information (14 percent vs. 1 percent). however, unlike hmsc participants, who do not have access to course reserves at the branch library, 7 percent of osu main-campus respondents used their mobile devices to find course reserves on the library website. see figure 2. 0% 10% 20% 30% 40% 50% 60% 70% directions contact information interlibrary loan course reserves my account a journal a book library hours an article branch 2016 main 2015 mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 16 figure 2. 2016 hmsc vs. 2015 osu main-campus participants reported searches while visiting the library website via a mobile device by percent of responses. it is possible that hmsc users with different affiliations might use the library site via a mobile device differently. these exploratory findings show that graduate students used the greatest variety of content via mobile devices. graduate students as a group reported using 11 of the 14 provided content choices via a mobile device while faculty reported using 8 of the 14. graduate students were the largest group (62 percent of respondents), which might explain why as a group they searched for more types of content via mobile devices. interestingly, faculty members and faculty researchers reported looking for a thesis via a mobile device, but no graduate students did. perhaps these graduate students had not yet learned about the usefulness of referencing past theses as a starting point for their own thesis writing. or perhaps they were only familiar with searching for journal articles on a topic. in contrast, faculty members might have been searching for specific theses for which they had provided advising or mentoring support. to help us make decisions about how to best direct users to library content via mobile devices, we asked respondents to indicate their searching behaviors and preferences. of the 16 hmsc respondents who answered this question, 12 (75 percent) used our web-scale discovery search box via mobile devices; 4 (25 percent) reported that they did. presumably these latter searchers were navigating to another database to find their sources. of 16 respondents, only 6 (38 percent) indicated that they looked for a specific library database (as opposed to the discovery tool) when using a mobile device. those respondents who were looking for a database tended to be looking for the web of science database, which makes sense for their field of study. when conducting searches for sources on their mobile devices, hmsc respondents employed a variety of search strategies: the 12 respondents who replied used a combination of author (75 percent), journal title (67 percent, keyword (67 percent), and book title (50 percent) searches when starting at the mobile version of the discovery tool. when asked about their preferred way to find sources, a majority of hmsc respondents reported that they tended to prefer a combination of searching and menu navigation while using the library website from mobile devices, while the remainder were evenly divided between preferring menu driven and search-driven discovery. while osu libraries does not currently provide links to any specific apps for source discovery, such as pubmed mobile or jstor browser, 13 (62 percent) of the hmsc respondents indicated they would be somewhat or very likely to use an app to access and use library services. this finding connects to the issue of reliable wireless access. medical graduate students had a wider array of apps available to them, but the primary reason they wanted to use these apps was because they provided a better searching experience in hospitals that had intermittent wireless access—an experience to which researchers at hmsc could relate.32 university website use behaviors on mobile devices to help situate respondents’ library use behaviors on mobile devices in comparison to the way they use other academic resources on mobile devices, we asked hmsc respondents to describe information technology and libraries | december 2017 17 their visits to resources on the osu (nonlibrary) website via mobile devices. compared to their use of the library site on a mobile device, respondents’ use of university services was higher: 43 percent (9 respondents) visited the university’s website via a mobile device at least once a week compared to only 9 percent (2 respondents) who visited the library site with that frequency. this makes sense because of the integral function many of these university services play in most university employees’ regular workflow. respondents indicated visiting key university sites including myosu (a portal webpage, visited by 60 percent of respondents), the hmsc webpage (55 percent), canvas (the university’s learning management system, visited by 50 percent of respondents), and webmail (45 percent). see figure 3. figure 3. university webpages hmsc respondents access on a mobile device by percent of responses. university resources such as campus maps, parking locations, and the graduate school website were frequently used by this population. the use of the first two makes sense as hmsc users are located off-site and need to use maps and parking guidance when they visit the main campus. the use of the graduate school website makes sense because the respondents were primarily graduate students and graduate school guidelines are a necessary source of information. interestingly, our advanced users are similar to undergraduates in that they primarily read email, information from social networking sites, and news on their mobile devices. 33 other research behaviors on mobile devices mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 18 we wanted to know what other research-related behaviors the hmsc respondents are engaged in via mobile devices to determine if there might be additional ways to support researchers’ workflows. we specifically asked about respondents’ reading, writing, and note-taking behaviors to learn how well these respondents have integrated them with their mobile usage behaviors. all respondents reported reading on their mobile device (see figure 4). email represented the most common reading activity (95 percent), followed by “quick reading” activities, such as reading social networking posts (81 percent), current news (81 percent), and blog posts (62 percent). smaller numbers used their mobile devices for academic or long-form reading, such as reading scholarly articles (33 percent) or books (19 percent). of those respondents who read articles and books on their mobile devices, only respondents highlighted or took notes using their mobile device. seven respondents used a citation manager on their mobile device: three used endnote, one used mendeley, one used pages, and one used zotero. one respondent used evernote on their mobile device, and one advanced user reported using specific data and database management software, websites, and apps related to their projects. more advanced and interactive mobilereading features, such as online spatial landmarks, might be needed before reading scholarly articles on mobile devices becomes more common.34 figure 4. what hmsc respondents reported reading on a mobile device by percent of responses. limitations this exploratory study had several limitations, most of which reflect the nature of doing research with a small population at a branch campus. this study had a small sample size, which limited observations of this population; however, future studies could use research techniques such as interviews or ethnographic studies to gather deep qualitative information about mobile-use 19% 33% 62% 81% 81% 95% 0% 20% 40% 60% 80% 100% 120% books academic or scholarly articles blog posts current news social networking posts (facebook, twitter, etc.) email percent of responses information technology and libraries | december 2017 19 behaviors in this population. a second limitation was that previous studies of the osu libraries mobile website used google analytics to compare survey results with what users were actually doing on the library website. unfortunately, this was not possible for this study. because of how hmsc’s network was set up, anyone at hmsc using the osu internet connections is assigned an ip address that shows a corvallis, oregon, location rather than a newport, oregon, location, which rendered parsing hmsc-specific users in google analytics impossible. the research behaviors of advanced researchers at a branch campus has not been well-examined; despite its limitations, this study provides beneficial insights into the behaviors of this user population. conclusion focusing on how advanced researchers at a branch campus use mobile devices while accessing library and other campus information provides a snapshot of key trends among this user group. these exploratory findings show that these advanced researchers are infrequent users of library resources via mobile devices and, contrary to our initial expectations, are not using mobile devices as a research resource while conducting field-based research. findings showed that while these advanced researchers do periodically use the library website via mobile devices, mobile devices are not the primary mode of searching for articles and books or for reading scholarly sources. mobile devices are most frequently used for viewing the library website when these advanced researchers are at home or in transit. the results of this survey will be used to address the hmsc knowledge gaps around use of library resources and research tools via mobile devices. both graduate students and faculty lack awareness of library resources and services and have unsophisticated library research skills. 35 while the osu main campus has library workshops for graduate students and faculty, these workshops have been inconsistently duplicated at the guin library. because the people working at hmsc come from such a wide variety of departments across osu that focus on marine sciences, hmsc has never had a library orientation. the results indicate possible value in devising ways to promote guin library’s resources and services locally, which could include highlighting the availability of mobile library access. while several participants mentioned using research tools like evernote, pages, or zotero on their mobile devices, most participants did not report enhancing their mobile research experience with these mobile-friendly tools. workshops specifically modeling how to use mobile-friendly tools and apps such as dropbox, evernote, goodreader, or browzine could help introduce the benefits of these tools to these advanced researchers. because wireless access is even more of a concern for researchers at this branch location than for researchers at the main campus, database-specific apps will be explored to determine if the use of searching apps could help alleviate inconsistent wireless access. if database apps that are appropriate for marine science researchers are available, these will be promoted to this user population. future research might involve follow-up interviews or focus groups, ethnographic studies, or interviews, which could expand the knowledge of these researchers’ mobile-device behaviors and mobile website use and advanced researchers | markland, rempel, and bridges doi:10.6017/ital.v36i4.9953 20 their perceptions of mobile devices. exploring the technology usage by these advanced researchers in their labs, including electronic lab notebooks or other tools, might be an interesting contrast to their use of mobile devices. in addition, as the hmsc campus grows with the expansion of the marine studies initiative, increasing numbers of undergraduates will use guin library. the ecar 2015 statistics show that current undergraduates own multiple internet-capable devices.36 presumably, these hmsc undergraduates will be likely to follow the trends seen in the ecar data. certainly, the plans to expand hmsc’s internet and wireless infrastructure will affect all its users. our mobile survey gave us insights into how a sample of the hmsc population uses the library’s resources and services. these observations will allow guin library to expand its services for the hmsc campus. we encourage other librarians to explore their unique user populations when evaluating services and resources. references 1 maria anna jankowska, “identifying university professors’ information needs in the challenging environment of information and communication

libraries | march 2010 t. michael silver monitoring network and service availability with open-source software silver describes the implementation of a monitoring system using an open-source software package to improve the availability of services and reduce the response time when troubles occur. he provides a brief overview of the literature available on monitoring library systems, and then describes the implementation of nagios, an open-source network monitoring system, to monitor a regional library system’s servers and wide area network. particular attention is paid to using the plug-in architecture to monitor library services effectively. the author includes example displays and configuration files. editor’s note: this article is the winner of the lita/ex libris writing award, 2009. l ibrary it departments have an obligation to provide reliable services both during and after normal business hours. the it industry has developed guidelines for the management of it services, but the library community has been slow to adopt these practices. the delay may be attributed to a number of factors, including a dependence on vendors and consultants for technical expertise, a reliance on librarians who have little formal training in it best practices, and a focus on automation systems instead of infrastructure. larger systems that employ dedicated it professionals to manage the organization’s technology resources likely implement best practices as a matter of course and see no need to discuss them within the library community. in the practice of system and network administration, thomas a. limoncelli, christine j. hogan, and strata r. chalup present a comprehensive look at best practices in managing systems and networks. early in the book they provide a short list of first steps toward improving it services, one of which is the implementation of some form of monitoring. they point out that without monitoring, systems can be down for extended periods before administrators notice or users report the problem.1 they dedicate an entire chapter to monitoring services. in it, they discuss the two primary types of monitoring—real-time monitoring, which provides information on the current state of services, and historical monitoring, which provides long-term data on uptime, use, and performance.2 while the software discussed in this article provides both types of monitoring, i focus on real-time monitoring and the value of problem identification and notification. service monitoring does not appear frequently in library literature, and what is written often relates to single-purpose custom monitoring. an article in the september 2008 issue of ital describes the development and deployment of a wireless network, including a perl script written to monitor the wireless network and associated services.3 the script updates a webpage to display the results and sends an e-mail notifying staff of problems. an enterprise monitoring system could perform these tasks and present the results within the context of the complete infrastructure. it would require using advanced features because of the segregation of networks discussed in their article but would require little or no extra effort than it took to write the single-purpose script. dave pattern at the university of huddersfield shared another perl script that monitors opac functionality.4 again, the script provided a single-purpose monitoring solution that could be integrated within a larger model. below, i discuss how i modified his script to provide more meaningful monitoring of our opac than the stock webpage monitoring plug-in included with our opensource networks monitoring system, nagios. service monitoring can consist of a variety of tests. in its simplest form, a ping test will verify that a host (server or device) is powered on and successfully connected to the network. feher and sondag used ping tests to monitor the availability of the routers and access points on their network, as do i for monitoring connectivity to remote locations.5 a slightly more meaningful check would test for the establishment of a connection on a port. feher and sondag used this method to check the daemons in their network.6 the step further would be to evaluate a service response, for example checking the status code returned by a web server. evaluating content forms the next level of meaning. limoncelli, hogan, and chalup discuss end-to-end monitoring, where the monitoring system actually performs meaningful transactions and evaluates the results.7 pattern’s script, mentioned above, tests opac functionality by submitting a known keyword search and evaluating the response.8 i implemented this after an incident where nagios failed to alert me to a problem with the opac. the web server returned a status code of 200 to the request for the search page. users, however, want more from an opac, and attempts to search were unsuccessful because of problems with the index server. modifying pattern’s original script, i was able to put together a custom check command that verifies a greater level of functionality by evaluating the number of results for the known search. n software selection limoncelli, hogan, and chalup do not address specific t. michael silver (michael.silver@ualberta.ca) is an mlis student, school of library and information studies, university of alberta, edmonton, alberta, canada. monitoring network and service availability with open-source software | silver 9 how-to issues and rarely mention specific products. their book provides the foundational knowledge necessary to identify what must be done. in terms of monitoring, they leave the selection of an appropriate tool to the reader.9 myriad monitoring tools exist, both commercial and open-source. some focus on network analysis, and some even target specific brands or model lines. the selection of a specific software package should depend on the services being monitored and the goals for the monitoring. wikipedia lists thirty-five different products, of which eighteen are commercial (some with free versions with reduced functionality or features); fourteen are opensource projects under a general public license or similar license (some with commercial support available but without different feature sets or licenses); and three offer different versions under different licenses.10 von hagen and jones suggest two of them: nagios and zabbix.11 i selected the nagios open-source product (http:// www.nagios.org). the software has an established history of active development, a large and active user community, a significant number of included and usercontributed extensions, and multiple books published on its use. commercial support is available from a company founded by the creator and lead developer as well as other authorized solution providers. monitoring appliances based on nagios are available, as are sensors designed to interoperate with nagios. because of the flexibility of a software design that uses a plug-in architecture, service checks for library-specific applications can be implemented. if a check or action can be scripted using practically any protocol or programming language, nagios can monitor it. nagios also provides a variety of information displays, as shown in appendixes a–e. n installation the nagios system provides an extremely flexible solution to monitor hosts and services. the object-orientation and use of plug-ins allows administrators to monitor any aspect of their infrastructure or services using standard plug-ins, user-contributed plug-ins, or custom scripts. additionally, the open-source nature of the package allows independent development of extensions to add features or integrate the software with other tools. community sites such as monitoringexchange (formerly nagios exchange), nagios community, and nagios wiki provide repositories of documentation, plug-ins, extensions, and other tools designed to work with nagios.12 but that flexibility comes at a cost—nagios has a steep learning curve, and usercontributed plug-ins often require the installation of other software, most notably perl modules. nagios runs on a variety of linux, unix, and berkeley software distribution (bsd) operating systems. for testing, i used a standard linux server distribution installed on a virtual machine. virtualization provides an easy way to test software, especially if an alternate operating system is needed. if given sufficient resources, a virtual machine is capable of running the production instance of nagios. after installing and updating the operating system, i installed the following packages: n apache web server n perl n gd development library, needed to produce graphs and status maps n libpng-devel and libjpeg-devel, both needed by the gd library n gcc and gnu make, which are needed to compile some plug-ins and perl modules most major linux and bsd distributions include nagios in their software repositories for easy installation using the native package management system. although the software in the repositories is often not the most recent version, using these repositories simplifies the installation process. if a reasonably recent version of the software is available from a repository, i will install from there. some software packages are either outdated or not available, and i manually install these. detailed installation instructions are available on the nagios website, in several books, and on the previously mentioned websites.13 the documentation for version 3 includes a number of quick-start guides.14 most package managers will take care of some of the setup, including modifying the apache configuration file to create an alias available at http://server.name/nagios. i prepared the remainder of this article using the latest stable versions of nagios (3.0.6) and the plug-ins (1.4.13) at the time of writing. n configuration nagios configuration relies on an object model, which allows a great deal of flexibility but can be complex. planning your configuration beforehand is highly recommended. nagios has two main configuration files, cgi.cfg and nagios.cfg. the former is primarily used by the web interface to authenticate users and control access, and it defines whether authentication is used and which users can access what functions. the latter is the main configuration file and controls all other program operations. the cfg_file and cfg_dir directives allow the configuration to be split into manageable groupsusing additional recourse files and the object definition files (see figure 1). the flexibility offered allows a variety of different structures. i group network 10 information technology and libraries | march 2010 devices into groups but create individual files for each server. nagios uses an objectoriented design. the objects in nagios are displayed in table 1. a complete review of nagios configuration is beyond the scope of this article. the documentation installed with nagios covers it in great detail. special attention should be paid to the concepts of templates and object inheritance as they are vital to creating a manageable configuration. the discussion below provides a brief introduction, while appendixes f–j provide concrete examples of working configuration files. n cgi.cfg the cgi.cfg file controls the web interface and its associated cgi (common gateway interface) programs. during testing, i often turn off authentication by setting use_authentication to 0 if the web interface is not accessible from the internet. there also are various configuration directives that provide greater control over which users can access which features. the users are defined in the /etc/nagios/htpasswd.users file. a summary of commands to control entries is presented in table 2. the web interface includes other features, such as sounds, status map displays, and integration with other products. discussion of these directives is beyond the scope of this article. the cgi.cfg file provided with the software is well commented, and the nagios documentation provides additional information. a number of screenshots from the web interface are provided in the appendixes, including status displays and reporting. n nagios.cfg the nagios.cfg file controls the operation of everything except the web interface. although it is possible to have a single monolithic configuration file, organizing the configuration into manageable files works better. the two main directives of note are cfg_file, which defines a single file that should be included, and cfg_dir, which includes all files in the specified directory with a .cfg extension. a third type of file that gets included is resource.cfg, which defines various macros for use in commands. organizing the object files takes some thought. i monitor more than one hundred services on roughly seventy hosts, so the method of organizing the files was of more than academic interest. i use the following configuration files: n commands.cfg, containing command definitions n contacts.cfg, containing the list of contacts and associated information, such as e-mail address, (see appendix h) n groups.cfg, containing all groups—hostgroups, servicegroups, and contactgroups, (see appendix g) n templates.cfg, containing all object templates, (see appendix f) n timeperiods.cfg, containing the time ranges for checks and notifications all devices and servers that i monitor are placed in directories using the cfg_dir directive: servers—contains server configurations. each file includes the host and service configurations for a physical or virtual server. devices—contains device information. i create individual files for devices with service monitoring that goes beyond simple ping tests for connectivtable 1. nagios objects object used for hosts servers

logically into a single file. for example, we monitor connectivity with fifty remote locations, and all fifty of them are placed in a single file. the resource.cfg file uses two macros to define the path to plug-ins and event handlers. thirty other macros are available. because the cgi programs do not read the resource file, restrictive permissions can be applied to them, enabling some of the macros to be used for usernames and passwords needed in check commands. placing sensitive information in service configurations exposes them to the web server, creating a security issue. n configuration the appendixes include the object configuration files for a simple monitoring situation. a switch is monitored using a simple ping test (see appendix j), while an opac server on the other side of the switch is monitored for both web and z39.50 operations (see appendix i). note that the opac configuration includes a parents directive that tells nagios that a problem with the gateway-switch will affect connectivity with the opac server. i monitor fifty remote sites. if my router is down, a single notification regarding my router provides more information if it is not buried in a storm of notifications about the remote sites. the web port, web service, and opac search services demonstrate different levels of monitoring. the web port simply attempts to establish a connection to port 80 without evaluating anything beyond a successful connection. the web service check requests a specific page from the web server and evaluates only the status code returned by the server. it displays a warning because i configured the check to download a file that does not exist. the web server is running because it returns an error code, hence the warning status. the opac search uses a known search to evaluate the result content, specifically whether the correct number of results is returned for a known search. i used a number of templates in the creation of this configuration. templates reduce the amount of repetitive typing by allowing the reuse of directives. templates can be chained, as seen in the host templates. the opac definition uses the linux-server template, which in turn uses the generic-host template. the host definition inherits the directives of the template it uses, overriding any elements in both and adding new elements. in practical terms, generic-host directives are read first. linux-server directives are applied next. if there is a conflict, the linuxserver directive takes precedence. finally, opac is read. again, any conflicts are resolved in favor of the last configuration read, in this case opac. n plug-ins and service checks the nagios plugins package provides numerous plug-ins, including the check-host-alive, check_ping, check_tcp, and check_http commands. using the plug-ins is straightforward, as demonstrated in the appendixes. most plugins will provide some information on use if executed with—help supplied as an argument to the command. by default, the plug-ins are installed in /usr/lib/nagios/ plugins. some distributions may install them in a different directory. the plugins folder contains a subfolder with usercontributed scripts that have proven useful. most of these plug-ins are perl scripts, many of which require additional perl modules available from the comprehensive perl archive network (cpan). the check_hip_search plug-in (appendix k) used in the examples requires additional modules. installing perl modules is best accomplished using the cpan perl module. detailed instructions on module installation are available online.15 some general tips: n gcc and make should be installed before trying to install perl modules, regardless of whether you are installing manually or using cpan. most modules are provided as source code, which may require compiling before use. cpan automates this process but requires the presence of these packages. n alternately, many linux distributions provide perl module packages. using repositories to install usually works well assuming the repository has all the needed modules. in my experience, that is rarely the case. table 2. sample commands for managing the htpasswd.users file create or modify an entry, with password entered at a prompt: htpasswd /etc/nagios/htpasswd.users <username> create or modify an entry using password from the command line: htpasswd -b /etc/nagios/htpasswd.users <username> <password> delete an entry from the file: htpasswd -d /etc/nagios/htpasswd.users <username> 12 information technology and libraries | march 2010 n many modules depend on other modules, sometimes requiring multiple install steps. both cpan and distribution package managers usually satisfy dependencies automatically. manual installation requires the installer to satisfy the dependencies one by one. n most plug-ins provide information on required software, including modules, in a readme file or in the source code for the script. in the absence of such documentation, running the script on the command line usually produces an error containing the name of the missing module. n testing should be done using the nagios user. using another user account, especially the root user, to create directories, copy files, and run programs creates folders and files that are not accessible to the nagios user. the best practice is to use the nagios user for as much of the configuration and testing as possible. the lists and forums frequently include questions from new users that have successfully installed, configured, and tested nagios as the root user and are confused when nagios fails to start or function properly. n advanced topics once the system is running, more advanced features can be explored. the documentation describes many such enhancements, but the following may be particularly useful depending on the situation. n nagios provides access control through the combination of settings in the cgi.cfg and htpasswd.users files. library administration and staff, as well as patrons, may appreciate the ability to see the status of the various systems. however, care should be taken to avoid disclosing sensitive information regarding the network or passwords, or allowing access to cgi programs that perform actions. n nagios permits the establishment of dependency relationships. host dependencies may be useful in some rare circumstances not covered by the parent–child relationships mentioned above, but service dependencies provide a method of connecting services in a meaningful manner. for example, certain opac functions are dependent on ils services. defining these relationships takes both time and thought, which may be worthwhile depending on any given situation. n event handlers allow nagios to initiate certain actions after a state change. if nagios notices that a particular service is down, it can run a script or program to attempt to correct the problem. care should be taken when creating these scripts as service restarts may delete or overwrite information critical to solving a problem, or worsen the actual situation if an attempt to restart a service or reboot a server fails. n nagios provides notification escalations, permitting the automatic notification of problems that last longer than a certain time. for example, a service escalation could send the first three alerts to the admin group. if properly configured, the fourth alert would be sent to the managers group as well as the admin group. in addition to escalating issues to management, this feature can be used to establish a series of responders for multiple on-call personnel. n nagios can work in tandem with remote machines. in addition to custom scripts using secure shell (ssh), the nagios remote plug-in executor (nrpe) add-on allows the execution of plug-ins on remote machines, while the nagios service check acceptor (nsca) add-on allows a remote host to submit check results to the nagios server for processing. implementing nagios on the feher and sondag wireless network mentioned earlier would require one of these options because the wireless network is not accessible from the external network. these add-ons also allow for distributed monitoring, sharing the load among a number of servers while still providing the administrators with a single interface to the entire monitored network. the nagios exchange (http://exchange.nagios .org/) contains similar user-contributed programs for windows. n nagios can be configured to provide redundant or failover monitoring. limoncelli, hogan, and chalup call this metamonitoring and describe when it is needed and how it can be implemented, suggesting self-monitoring by the host or having a second monitoring system that only monitors the main system.16 nagios permits more complex configurations, allowing for either two servers operating in parallel, only one of which sends notifications unless the main server fails, or two servers communicating to share the monitoring load. n alternative means of notification increase access to information on the status of the network. i implemented another open-source software package, quickpage, which allows nagios text messages to be sent from a computer to a pager or cell phone.17 appendix l shows a screenshot of a firefox extension that displays host and service problems in the status bar of my browser and provides optional audio alerts.18 the nagios community has developed a number of alternatives, including specialized web interfaces and rss feed generators.19 monitoring network and service availability with open-source software | silver 13 n appropriate use monitoring uses bandwidth and adds to the load of machines being monitored. accordingly, an it department should only monitor its own servers and devices, or those for which it has permission to do so. imagine what would happen if all the users of a service such as worldcat started monitoring it! the additional load would be noticeable and could conceivably disrupt service. aside from reasons connected with being a good “netizen,” monitoring appears similar to port-scanning, a technique used to discover network vulnerabilities. an organization that blithely monitors devices without the owner’s permission may find their traffic is throttled back or blocked entirely. if a library has a definite need to monitor another service, obtaining permission to do so is a vital first step. if permission is withheld, the service level agreement between the library and its service provider or vendor should be reevaluated to ensure that the provider has an appropriate system in place to respond to problems. n benefits the system-administration books provide an accurate overview of the benefits of monitoring, but personally reaping those benefits provides a qualitative background to the experience. i was able to justify the time spent on setting up monitoring the first day of production. one of the available plug-ins monitors sybase database servers. it was one of the first contributed plug-ins i implemented because of past experiences with our production database running out of free space, causing the system to become nonfunctional. this happened twice, approximately a year apart. each time, the integrated library system was down while the vendor addressed the issue. when i enabled the sybase service checks, nagios immediately returned a warning for the free space. the advance warning allowed me to work with the vendor to extend the database volume with no downtime for our users. that single event convinced the library director of the value of the system. since that time, nagios has proven its worth in alerting it staff to problem situations, providing information on outage patterns both for in-house troubleshooting and discussions with service providers. n conclusion monitoring systems and services provides it staff with a vital tool in providing quality customer service and managing systems. installing and configuring such a system involves a learning curve and takes both time and computing resources. my experiences with nagios have convinced me that the return on investment more than justifies the costs. references 1. thomas a. limoncelli, christina j. hogan, and strata r. chalup, the practice of

| june 2021 https://doi.org/10.6017/ital.v40i2.12987 abstract as libraries, archives, and museums make unique digital collections openly available via digital library platforms, they expose these resources to users who may wish to cite them. often several urls are available for a single digital object, depending on which route a user took to find it, but the chosen citation url should be the one most likely to persist over time. catalyzed by recent digital collections migration initiatives at indiana university libraries, this study investigates the prevalence of persistent urls for digital objects at peer institutions and examines the ways their platforms instruct users to cite them. this study reviewed institutional websites from the digital library federation’s (dlf) published list of 195 members and identified representative digital objects from unique digital collections navigable from each institution’s main web page in order to determine persistent url formats and citation options. findings indicate an equal split between offering and not offering discernible persistent urls with four major methods used: handle, doi, ark, and purl. significant variation in labeling persistent urls and inclusion in item-specific citations uncovered areas where the user experience could be improved for more reliable citation of these unique resources. introduction libraries, archives, and museums often make their unique digital collections openly available in digital library services and in different contexts, such as digital library aggregators like the digital public library of america (dpla, https://dp.la/) and hathitrust digital library (https://www.hathitrust.org/). as a result, there can be many urls available that point to digital objects within these collections. take, for example, image collections online (http://dlib.indiana.edu/collections/images) at indiana university (iu), a service launched in 2007 featuring open access iu image collections. users discover images on the site through searching and browsing and its collections are also shared with dpla. the following urls exist for the digital object shown in figure 1, an image from the building a nation: indiana limestone photograph collection: • the url as it appears in the browser in image collections online:

http://purl.dlib.indiana.edu/iudl/images/vac5094/vac509401446. citation instructions given to authors in major style guides explicitly mention using the best possible form of a resource’s url: “[i]t is important to choose the version of the url that is most likely to continue to point to the source cited.”1 of the three urls above, the second is a purl, or persistent url (https://archive.org/services/purl/), which is why both image collections online and dpla instruct users to bookmark or cite it. other common methods for issuing and maintaining persistent urls include digital object identifiers (doi, https://www.doi.org/), handles (http://handle.net/), and archival resource keys (ark, https://n2t.net/e/ark_ids.html). all of those have been around since the late 1990s to early 2000s. at indiana university libraries, recent efforts have focused on migrating digital collections to new digital library platforms, mainly based on the open source samvera repository software (https://samvera.org/). as part of these efforts, we wanted to survey how peer institutions were http://purl.dlib.indiana.edu/iudl/images/vac5094/vac5094-01446

persistent, citable urls for digital objects to determine if a prevailing approach had emerged since indiana university libraries’ previous generation of digital library services were developed in the earlyto mid-2000s. besides having the capability of creating and reliably serving these urls, our digital library platforms need to make these urls easily accessible to users, preferably along with some assertion that the urls should be used when citing digital objects and collections instead of the many non-persistent urls also directing to those same digital objects and collections. although libraries, archives, and museums have digitized and made digital objects in digital collections openly accessible for decades using several methods for providing persistent, citable urls, how do institutions now present digital object urls to people who encounter, use, and cite them? by examining digital collections within a large population of digital library institutions’ websites, this study aims to discover 1. what methods of url persistence are being employed for digital objects by digital library institutions? 2. how do these institutions’ websites instruct users to cite these digital objects? literature review the study of digital objects in the literature often takes a philosophical perspective in attempting to define them. moreover, practical accounts of digital object use and reuse note the challenges associated with infrastructure, retrieval, and provenance. much of the literature about common methods of persistent url resolution comes from individuals and entities who developed and maintain these standards, as well as overviews of the persistent url resolution methods available. finally, several studies have investigated the problem of “link rot” by tracking the availability of web-hosted resources over time. allison notes the generations of philosophical thought that it took to recognize common characteristics of physical objects and the difficulty in understanding an authentic version of a digital object, especially with different computer hardware and software changing the way digital objects appear.2 hui also investigates the philosophical history of physical objects to begin to define digital objects through his methods of datafication of objects and objectification of data, noting that digital objects can be approached in three phases: objects, data, and networks, in order to define them.3 lynch is also concerned with determining the authenticity of digital objects and challenges inherent in the digital realm. in describing digital objects, he creates a hierarchy with raw data at the bottom, elevated to interactive experiential works at the top which elicit the fullest emotional connection contributing to the authentic experience of the work.4 the literature often examines digital objects from the practitioner’s perspective, such as the publishing industry’s difficulty in repurposing digital objects for new publishing products. publishers in benoit and hussey’s 2011 case study note the tension between managers and technical staff concerning assumptions about what their computer system could automatically do with their digital objects; their digital objects always require some human labor and intervention to be accurately described and retrievable later. 5 dappert et al. note the need to describe a digital object’s environment in order to be able to reproduce it in their work with the premis data dictionary for preservation metadata (https://www.loc.gov/standards/premis/).6 strubulis et al. provide a model for digital object provenance using inference and resource description framework (rdf) triples (https://w3.org/rdf/) since storing full provenance information for

complex digital objects, such as the large amount of mars rover data they offer as an example, would be cost prohibitive.7 in 2001, arms describes the landscape of persistent uniform resource names (urn) of handles, purls, and dois near the latter’s inception.8 recent work by koster explains the persistent identifier methods most in use today and examines current infrastructure practices for maintaining them.9 the persistent link resolution method most prominently featured in the literature is the digital object identifier (doi). beginning in 1999, those behind developing and implementing doi have explained its inception, development, and trajectory, continuing with paskin’s deep explanation in 2002 of the reasons why doi exist and the technology behind the service. 10 discipline-specific research notes the utility of doi. sidman and davidson and weissberg studied doi for the purposes of automating the supply chain in the publishing industry.11 derisi, kennison, and twyman, on behalf of the public library of science (plos) announced their 2003 decision to broadly implement doi, followed by additional disciplinespecific encouragement of the practice by skiba in nursing education and neumann and brase in molecular design.12 the archival resource key (ark) is an alternative permanent link resolution scheme. since 2001, the open-source ark identifier offers a self-hosted solution for providing persistent access to digital objects, their metadata, and a maintenance commitment.13 recently, duraspace working groups have planned for further development and expansion of ark with the arks in the open project (https://wiki.lyrasis.org/display/arks/arks+in+the+open+project). persistent urls (purls) have been used to provide persistent access to digital objects for nearly 20 years, and their use in the library community is well documented. shafer, weibel, and jul anticipate uniform resource names becoming a web standard and offer purls as an intermediate step to aid in urn development.14 shafer also explained how oclc uses purls and alternate routing methods (arms) to properly direct global users to oclc resources.15 purls are also used to provide persistent access to government information and were seen by the cendi persistent identification task group as essential to their early efforts to implement the federal enterprise architecture (fea) and a theoretical federal persistent identification resolver.16 digital objects and collections should ideally be accessible via urls that work beyond the life of any one platform, lest the materials be subjected to “link rot,” or the process of decay when previously working links no longer correctly resolve. ducut et al. investigated 1994–2006 medline abstracts for the presence of persistent link resolution services such as handle, purl, doi, and webcite and found 20% of the links were inaccessible in 2008.17 mcmurry et al. investigated link rot in life sciences data and suggested practices for formatting links for increased persistence and approaches for versioning.18 the topic of link rot has been examined as early as 2003, in markwell and brooke’s “broken links: just how rapidly do science education hyperlinks go extinct,” cited by multiple link rot studies. ironically, this article is no longer accessible at the cited url.19 methodology this study sought a set of digital objects within library institutions’ digital collections websites. to locate examples of publicly accessible digital objects in digital collections, this study collected institutional websites from the digital library federation’s (dlf) published list of 195 members https://wiki.lyrasis.org/display/arks/arks+in+the+open+project information technology and libraries june 2021 persistent urls and citations offered for digital objects by digital libraries | homenda 5 as of august 2019.20 subsequent investigation aimed to find one representative digital object from unique digital collections navigable from each institution’s main web page. this study aimed to locate digital collections that met the following criteria: 1. collections are openly available. 2. collections are in a repository service, as opposed to highlighted content visible on an informational web page or blog. 3. collections are gathered within a site or service that contains multiple collections, as opposed to individual digital project websites, when possible. 4. collections are unique to an institution, as opposed to duplicated or licensed content. these criteria were developed in an effort to find unique, publicly accessible digital objects within each institution’s digital collections. to be sure, users search for and discover materials in a variety of ways and in numerous services, but studying the information-seeking behavior of users looking for digital objects or digital collections is outside the scope of this study. ultimately, digital collections indexed by search engines or available in aggregator services like dpla often contain links to collections and objects in their institutionally hosted platforms. users who discover these materials are likely to be directed to the sites this study investigated. for the purposes of this study, at least one digital collection was investigated from each dlf institution. multiple sites for an institution were investigated when more than one publicly accessible site or service met the above criteria. when digital collections at an institution were delivered only through the library catalog discovery service, reasonable attempts were made to delimit discoverable digital collections content. in total, 183 digital collections were identified for this study. once digital collections were located, subsequent investigation aimed to locate individual digital objects within them. while digital objects represent diverse materials available in a variety of formats, for ease of comparing approaches between institutions, a mixture of ind ividual digital images, multipage digital items, and audiovisual materials were examined. objects for this study were primarily available in websites containing a variety of collections and format types with common display characteristics despite format differences, and no additional efforts were made to locate equal or proportional digital object formats at each institution. one representative digital object was identified per digital collection, totaling 183 digital objects. once a digital object was located at an institution, the object’s unique identifier, format, persistent url, persistent url label, method of link resolution (if identifiable), and citation were collected with particular focus on the object’s persistent url, if available. commonly used persistent url types and their url components can be identified, as seen in table 1; however, any means of persistence was collected if clearly identified. after examining initial results, the object’s provided citation, if available, was added to the list of data collected since many digital collection platforms provide recommended citations for individual objects. information technology

a single digital collection site or service that met the selection criteria for this study. some appear to have multiple digital collection repositories, often separated by digital object format or library department, and many institutions have collections that are only publicly accessible through discrete project web sites, such as digital exhibits or focused digital humanities research projects. out of 195 dlf member institutions, 171 had publicly accessible digital collections. of these 171 institutions, 153 had digital collections services/sites that adhered to the criteria of this study, while 21 had only project-focused digital collections sites. since several institutions had more than one digital collection platform accessible via their main institutional website, a population of 183 digital collections were investigated. one representative digital object from each collection was gathered, consisting of 107 digital images, 73 multipage items, and 3 audiovisual items (totaling 183). table 2. number of instances of digital collection platforms identified platform number percentage of total (183) custom or unidentifiable 53 29% contentdm 46 25% islandora 19

where software was identifiable, 17 different platforms were used and the top five were contentdm, islandora, dspace, samvera (hyrax, avalon, curation concerns, etc.), and omeka. table 3. occurrence

persistent link labels were reported,21 each occurring only once. as seen in table 3, the numbers of digital objects with and without publicly accessible persistent (or seemingly persistent) links were nearly equal. among the digital objects with persistent links, the majority claimed persistence without a discernible resolution method, with the rest divided between handle, ark, doi, and purl. these objects also had 33 different labels for these links in the public-facing interface. the top five labels were: permalink (22), identifier (13), permanent link (7), uri (5), and persistent link (3). as seen in table 4, the majority of digital objects surveyed had a unique item identifier in their publicly viewable item record. the majority did not offer a citation in the item’s publicly viewable record. among items that offered citations, the majority contained a link to the item, and three offered downloadable citation formats only, such as endnote, zotero, and mendeley. information

to a resource, it follows that providing persistent urls to resources such as digital objects or digital collections is also a good practice. it is encouraging to see a large number of institutions surveyed providing urls that persist (or claim to persist). providing persistent access to a unique digital resource implies a level of commitment to maintaining its url into the future, requiring policies, technology, and labor resources, further augmented by costs associated with registering certain types of identifiers like doi.22 it is likely that institutions not providing persistent (or not obviously persistent) urls are either internally committing to preserving their objects, collections, and services through means not known to end users; are constrained by technological limitations of their digital collection platforms; hope to develop or adopt new digital library services that offer these capabilities; or lack the resources to offer persistent urls. the four commonly used methods of persistent link resolution—doi, handle, ark, and purl— have been used for nearly 20 years, and it is not surprising that alternative observable methods were seldom encountered in this study. handles were the most common persistent url method, which seems related to the digital library platform used by an institution. dspace distributions are pre-bundled with handle server software, for example, and 12 out of 27 platforms serving digital objects with handles were based on dspace (https://duraspace.org/dspace/). when choosing to implement or upgrade a digital library platform, institutions often consider several available options. choosing a platform that offers the ability to easily create and maintain persistent urls might be less burdensome than making urls persist via independent or alternative means. thirty-three digital objects offered links that had labels implying some sort of persistence but lacked information describing the methods used or url components consistent with commonly used methods, as seen in table 1. to achieve persistence, there might be a combination of url rewriting, locally implemented solutions, or nonpublic persistent urls existing. it would benefit users, increasingly aware of the need to cite digital objects using persistent links, for digital object platforms that offer persistent linking to explicitly state that fact and ideally offer some evidence of the resolution method used. researchers will be looking for citable persistent links that offer https://duraspace.org/dspace/ information technology and libraries june 2021 persistent urls and citations offered for digital objects by digital libraries | homenda 9 some cues signifying their persistence, whether it is clearly indicated language on the website or a url pattern consistent with the four major methods commonly used. the amount of variation in labeling persistent links was surprising. commonly used digital library software platforms have default ways of labeling these fields. nearly all of the “reference url” labels encountered are in contentdm sites, for example. since the concept of offering a persistent link to a digital object is not uncommon, perhaps there can be a more consistent approach to choosing the label for this content. when a researcher finds a digital object in an institutional digital library service, they might want to cite that object. accurately citing resources in all formats is an essential research skill, and digital library platforms often try to aid users by providing dynamically generated or pre-populated citations based on unique metadata associated with that object. it was somewhat surprising to encounter these types of citation helpers that did not include persistent links. since a digital object’s preferred persistent link is often different than the url visible in the browser, efforts should be made to make citations available containing persistent links. there are institutions with digital collections that were not examined in this study due to a number of factors. first, this study examined the 195 institutions who were members of the digital library federation, and there are 2,828 four-year postsecondary institutions in the united states as of 2018.23 additional study could expand perceptions about persistent links for digital objects when looking beyond the dlf member institutions, which are predominantly four-year postsecondary institutions but also contain museums, public libraries, and other cultural heritage organizations. an alternative approach to collecting this data would be to conduct user testing focused on finding and citing digital objects from a number of institutions. this approach was not used, however, since the initial goal of this study was to see how peer digital library institutions have employed persistent links and citations across a broad yet contained spectrum. as one librarian with extensive digital library experience, my approach to locating these platforms and resources is subject to subconscious bias i may have accumulated over my professional career, but i would hope that my experience makes me more able to locate these platforms and materials than the average user. digital library platforms are numerous, and often institutions have several of them with varying degrees of public visibility or connectivity to their institution’s main library website. this study’s findings for any particular institution are not as authoritative as self-reported information from the institution itself. while a survey aimed at collecting direct responses from institutions might have yielded more accuracy, a potentially low response rate would also make it difficult to truly know what methods of persistent linking peer institutions are employing, especially with the majority of these resources being openly findable and accessible. still, further study with self reported information could shed more light on the decisions to provide certain methods of persistent links to objects within their chosen digital collection platforms. moreover, it is possible that some digital object formats are more likely to have persistent urls than others. newer formats such as three-dimensional digital objects, commonly cited resources like data sets, and scholarship held in institutional repositories could be available in digital library services similar to those surveyed in this study with different persistent url characteristics. additional study could aim to survey populations of digital objects by format across multiple institutions to investigate any correlation between persistent urls and object format. information technology and libraries june 2021 persistent urls and citations offered for digital objects by digital libraries | homenda 10 conclusion unique digital collections at digital library institutions are made openly accessible to the pu blic in a variety of ways, including digital library software platforms and digital library aggregator services. regardless of how users find these materials, best practices require users to cite urls for these materials that are most likely to continue to provide access to them. persistent urls are a common way to ensure cited urls to digital objects remain accessible. commonly used methods of issuing and maintaining persistent urls can be identified in digital object records within digital collection platforms available at these institutions. this study identified characteristics about these digital objects, their platforms, prevalence of persistent urls in their records, and the way these urls are presented to users. findings indicate that dlf member institutions are split evenly between providing and not providing publicly discernible persistent urls with wide variation on how these urls are presented and explained to users. decisions made in developing and maintaining digital collection platforms and the types of urls made available to users impact which urls users cite and the possibility of others encountering these resources through these citations. embarking on this study also was prompted by digital collection migrations at indiana university, and these findings provide us interesting examples of persistent url usage at other institutions and ways to improve the user experience in digital collection platforms. endnotes 1 the chicago manual of style online (chicago: university of chicago press, 2017), ch. 14, sec. 7. 2 arthur allison et al.,

methodology results discussion conclusion endnotes let’s get virtual: examination of best practices to provide public access to digital versions of three-dimensional objects tanya m. johnson information technology and libraries | june 2016 39 abstract three-dimensional objects are important sources of information that should not be ignored in the increasing trend towards digitization. previous research has not addressed the evaluation of digitized versions of three-dimensional objects. this paper first reviews research concerning such digitization, in both two and three dimensions, as well as public access in this context. next, evaluation criteria for websites incorporating digital versions of three-dimensional objects are extrapolated from previous research. finally, five websites are evaluated, and suggestions for best practices to provide public access to digital versions of three-dimensional objects are proposed. introduction much of the literature surrounding the increased efforts of libraries and museums to digitize content has focused on two-dimensional forms, such as books, photographs, or paintings. however, information does not only come in two dimensions; there are sculptures, artifacts, and other three-dimensional objects that have been unfortunately neglected by this digital revolution. as one author stated, “while researchers do not refer to three-dimensional objects as commonly as books, manuscripts, and journal articles, they are still important sources of information and should not be taken for granted” (jarrell 1998, 32). the importance of three-dimensional objects as information that can and should be shared is not a new phenomenon; indeed, as early as 1887, museologists and educators forwarded the view that “museums were in effect libraries of objects” that provided information not supplied by books alone (given and mctavish 2010, 11). however, it is only recently, with the advent of newer technological mechanisms, that such objects could be shared with the public on a larger scale. no longer do people need to physically visit museums to experience and learn from threedimensional objects. rather, various techniques have been utilized to place digital versions of such objects on the websites of museums and archives, and projects have been created by various universities in order to enhance that digital experience. nevertheless, as newell (2012) states: collections-holding institutions increasingly regard digital resources as additional objects of significance, not as complete replacements for the original. digital technologies work best when they enable people who feel connected to museum objects to have the freedom to deepen these tanya m. johnson (tmjohnso@gmail.com), a recent mlis degree graduate from the school of communication & information, rutgers, the state university of new jersey, is winner of the 2016 lita/ex libris student writing award. mailto:tmjohnso@gmail.com let’s get

extend outsiders’ understandings of the objects’ cultural contexts. the raison d’être of museums and other cultural institutions remains centred on the primacy of the object and in this sense continues to privilege material authenticity. (303) in this regard, three-dimensional visualization of physical objects can be seen as the next step for museums and cultural heritage institutions that seek to further patrons’ connection to such objects via the internet. indeed, in this digital age, the goals of museums and archives are changing, converging with those of libraries to focus more efforts on providing information to the public, and, along with the growing trend to digitize information contained within libraries, there has been a concomitant trend to digitize the contents of museums in order to provide greater public access to collections (given and mctavish 2010). in light of this progress, this paper will review various methods of presenting three-dimensional objects to the public on the internet and, based on an evaluation of five digital collections, attempt to provide some advice as to best practices for museums or institutions seeking to digitize such objects and present them to the public via a digital collection. literature review two-dimensional digitization there are many ways to present digital versions of three-dimensional objects on a webpage, ranging from simple two-dimensional photography to complicated three-dimensional scanning and rendering. beginning on the simpler end of the scale, bincsik, maezaki, and hattori (2012) describe the process of photographing japanese decorative art objects in order to create an image database of objects from multiple museums. specifically, the researchers explain that they need high quality photographs showing each object in all directions, as well as close-up images of fine details, in order to recreate the physical research experience as closely as possible. they also note that, for the same reason, the context of each object must be recorded, including photographs of any wrapping or storage materials and accompanying documentation. for this project, the researchers utilized nikon professional or semi-professional cameras, with zoom and macro lenses, and often used small apertures to increase depth-of-field. at times, they also took measurements of the objects in order to assist museums in maintaining accurate records. the raw image files were then processed with programs such as adobe photoshop, saved as original tif files, and converted into jpeg format for upload. despite the success of the project, the researchers also noted the limitations of digitizing three-dimensional objects: with decorative art objects some information is inevitably lost, such as the weight of the object, the feeling of its surface texture or the sense of its functionality in terms of proportions and balance. digital images clearly can fulfill many research objectives, but in some cases they can only be used as references. one objective of the decorative arts database is to advise the researcher in selecting which objects should be examined in person. (bincsik, maezaki, and hattori 2012, 46) one difficulty with photography, particularly when digitizing artwork, is that color is a function of light. thus, a single object will often appear to be different colors when photographed in different lighting conditions using conventional digital cameras, which process images using rgb filters. information technology and libraries | june 2016 41 more accurate representations of objects can be acquired using multispectral imaging, which uses a higher number of parameters (the international standard is 31, compared to rgb’s 3) in order to obtain more information about the reflectance of an object at any particular point in space (novati, pellegri, and schettini 2005). multispectral imaging, however, is very expensive and, despite some researchers’ attempts to create affordable systems (e.g., novati, pellegri, and schettini 2005), the acquisition of multispectral images is generally limited to large institutions with considerable funding (chane et al. 2013). the use of two-dimensional photography to digitize objects is not limited to the arts; in the natural sciences, different types of photographic equipment have been developed to document existing collections and enhance scientific observation. gigapixel imaging, for example, has been utilized to allow museum visitors to virtually explore large petroglyphs located in remote locations as well as for documentation and viewing of dinosaur bone specimens that are not on public display (louw and crowley 2013). this technology consists of taking many, very high resolution photographs that are then, via computer software, “aligned, blended, and stitched” together to create one extremely detailed composite image (louw and crowley 2013, 89–90). robotic systems, such as gigapan, have been developed to speed up the process and permit rapid recording and processing of the necessary area. once the gigapixel image is created, it can then be uploaded and displayed on the web in dynamic form, including spatial navigation of the image with embedded text, audio, or video at specific locations and zoom levels to provide further information (louw and crowley 2013). various types of gigapixel imaging, including the gigapan system, have also been used to digitize important collections of biological specimens, particularly insects, which are often stored in large drawers. one study examined the documentation of entomological specimens by “whole-drawer imaging” using various gigapixel imaging technologies (holovachov, zatushevsky, and shydlovsky 2014). the researchers explained that different gigapixel imaging systems (many of which are commercial and proprietary) utilize different types of cameras and lenses, as well as different types of software for processing. however, despite the expensive cost of some commercially available systems, it is possible for museums and other institutions to create their own, economically viable versions. the system created by holovachov, zatushevsky, and shydlovsky utilized a standard slr camera, fitted with a macro lens and attached to an immovable stand. the researchers manually set up lighting, focus, aperture, and other settings, and moved the insect drawer along a pre-determined grid pattern in order to obtain the multiple overlapping photographs necessary to create a large gigapixel image. they used a freely available stitching software program and manually corrected stitching artifacts and color balance issues that resulted from the use of a non-telecentric lens.1 despite the lower cost of their individualized system, however, the researchers noted that the process was much more time-consuming and necessitated more labor from workers digitizing the collection. moreover, technologically speaking, the researchers emphasized the limits of two-dimensional imaging, given that the 1the difference between telecentric and non-telecentric lenses is explained by the researchers: “contrary to ordinary photographic lenses, object-space telecentric lenses provide the same object magnification at all possible focusing distances. an object that is too close or too far from the focus plane and not in focus, will be the same size as if it were in focus. there is no perspective error and the image projection is parallel. therefore, when such a lens is used to take images of pinned insects in a box, all vertical pins will appear strictly vertical, independent of their position within the camera’s field of view” (holovachov, zatushevsky, and shydlovsky 2014, 7). let’s get virtual: examination of best practices to provide public access to digital versions of three-dimensional objects | johnson | doi:10.6017/ital.v35i2.9343 42 “diagnostic characteristics of three-dimensional insects,” as well as the accompanying labels, are often invisible when a drawer is only photographed from the top. thus, the researchers concluded that, ultimately, “the whole-drawer digitizing of insect collections needs to be transformed from two-dimensions to three-dimensions by employing complex imaging techniques (simultaneous use of multiple cameras positioned at different angles) and a digital workflow” (holovachov, zatushevsky, and shydlovsky 2014, 7). three-dimensional digitization given the goal of obtaining as accurate a representation as possible when digitizing objects, many researchers have turned to the use of various techniques in order to obtain three-dimensional data. acquiring a three-dimensional image of an object takes place in three steps: 1. preparation, during which certain preliminary activities take place that involve the decision about the technique and methodology to be adopted as well as the place of digitization, security planning issues, etc. 2. digital recording, which is the main digitization process according to the plan from phase 1. 3. data processing, which involves the modeling of the digitized object through the unification of partial scans, geometric data processing, texture data processing, texture mapping, etc. (pavlidis et al. 2007, 94) steps 2 and 3 have been more technically described as (2) obtaining data from an object to create point clouds (from thousands to billions of x,y,z coordinates representing loci on the object); and (3) processing point clouds into polygon models (creating a surface on top of the points), which can then be mapped with textures and colors (metallo and rossi 2011). there are several techniques that can be utilized to acquire three-dimensional data from a physical object. table 1 explains the four general methods most commonly used by museums. information technology and libraries | june 2016 43 type description positives negatives approx. price range laser scanning a laser source emits

computed tomography (ct) uses rotating x-rays to create twodimensional slices, which can then be reconstructed into three-dimensional images both types can view the interior and exterior of an object; ct can be used for reflective or translucent objects; mri can image soft tissues no color information; mri requires object to have high water content $200,000– $2,000,000 table 1. description of four general methods of acquiring three-dimensional data about physical objects (table information compiled by reference to pavlidis et al. 2007; metallo and rossi 2011; abel et al. 2011; and berquist et al. 2012). the type of three-dimensional digitization used can ultimately depend upon the types of objects to be imaged or the type of data needed. for example, in digitizing human skeletal collections, one study explained that three-dimensional laser scanning was an advantageous technique to create models of bones for preservation and analysis, but cautioned that ct scans would be needed to examine the internal structures of such specimens (kuzminsky and gardiner 2012). another study let’s get virtual: examination of best practices to provide public access to digital versions of three-dimensional objects | johnson | doi:10.6017/ital.v35i2.9343 44 utilized several techniques in an attempt to decipher graffiti inscriptions on ancient roman pottery shards, ultimately concluding that high-resolution photography (similar to gigapixel imaging) and three-dimensional laser scanning both provided detailed and helpful data (montani et al. 2012). additionally, sometimes multiple types of digitization can be used for the same objects with similar results. one study, for example, obtained virtually equivalent threedimensional models of the same object using laser scanning and two types of photogrammetry (lerma and muir 2014). most recently, researchers have been utilizing combinations of digitization techniques to obtain the most accurate representations possible. chane et al. (2013), for example, examined methods of combining three-dimensional digitization with multispectral photography in order to obtain enhanced information concerning the physical object in question. the researchers explained that combining the two processes is difficult because, in order to obtain multispectral textural data that is mapped to geometric positions, the object must be imaged from identical locations by multiple scanners/cameras or else the data processing that combines the two types of data becomes extremely complex. as a compromise, the researchers created a system of optical tracking based on photogrammetry techniques that permits the collection and integration of geometric positioning data and multispectral textures utilizing precise targeting procedures. however, the researchers noted that most systems integrating multispectral photography with threedimensional digitization tended to be quite bulky, did not adapt easily to different types of objects, and needed better processing algorithms for more complex three-dimensional objects (chane et al. 2013). public access to three-dimensionally digitized objects despite museums’ growing focus on increasing public access to collections via digitization (given and mctavish 2010), there is very little literature addressing public access to three-dimensionally digitized objects. indeed, studies in this realm tend to focus on the technological aspects of either the modeling of specific objects or collections or website viewing of three-dimensional models. for example, abate et al. (2011) described the three-dimensional digitization of a particular statue from the scanning process to its ultimate depiction on a website. the researchers explained in detail the particular software architecture utilized in order to permit the remote rendering of the three-dimensional model on users’ computers via a java applet without compromising quality or necessitating download of potentially copyrighted works. by contrast, literature concerning the digital michelangelo project, during which researchers three-dimensionally digitized various michelangelo works, focused on the method used to create an accurate three-dimensional model, complete with color and texture mapping, and a visualization tool (dellepiane et al. 2008). one study did describe a project that was designed to place three-dimensional data about various cultural artifacts in an online repository for curators and other professionals (hess et al. 2011). this repository was contained within database management software, a web-based interface was designed for searching, and user access to three-dimensional images and models was provided via an activex plugin. despite the potential of the prototype, however, it appears that the project has ceased,2 and the institution’s current three-dimensional imaging project is focused on the design 2see http://www.ucl.ac.uk/museums/petrie/research/research-projects/3dpetrie/3d_projects/3d-projects-past/ecurator. http://www.ucl.ac.uk/museums/petrie/research/research-projects/3dpetrie/3d_projects/3d-projects-past/e-curator http://www.ucl.ac.uk/museums/petrie/research/research-projects/3dpetrie/3d_projects/3d-projects-past/e-curator information technology and libraries | june 2016 45 of a traveling exhibition incorporating, among other things, three-dimensional models of artifacts and physical replicas created from such models.3 studies that do address public access directly tend to focus on the improvement of museum websites generally. for example, in terms of user expectations of museum websites, one study found that approximately 63 percent of visitors to a museum’s website did so in order to search the digital collection (kravchyna and hastings 2002). another study found four types of museum website users, who each had different needs and expectations of sites. relevantly, educators sought collections that were “the more realistic the better,” including suggestions like incorporating three-dimensional simulations of physical objects so that students could “explore the form, construction, texture and use of objects” (cameron 2003, 335). further, non-specialist users “value free choice learning” and “access online collections to explore and discover new things and build on their knowledge base as a form of entertainment” (cameron 2003, 335). similarly, some studies have addressed the incorporation of web 2.0 technologies into museum websites. srinivasan et al. (2009), for example, argue that web 2.0 technologies must be integrated into museum catalogs rather than simply layered over existing records because users’ interest in objects is increased by participation in the descriptive practice. an implementation of this concept is found in hunter and gerber’s (2010) system of social tagging attached to threedimensional models. this paper is an effort to address the gap between the technical process of digitizing and presenting three-dimensional objects on the web and the user experience of such. through the evaluation of five websites, this paper will provide some guidance for the digitization of threedimensional objects and their presentation in digital collections for public access. methodology and evaluative criteria evaluations of digital museums are not as prevalent as evaluations of digital libraries. however, given the similar purposes of digital museums and digital libraries, it is appropriate to utilize similar criteria. for digital libraries, saracevic (2000) synthesized evaluation criteria into performance questions in two broad areas: (a) user-centered questions, including how well the digital library supports the society or community served, how well it supports institutional or organizational goals, how well it supports individual users’ information needs, and how well the digital library’s interface provides access and interaction; and (b) systemcentered questions, including hardware and network performance, processing and algorithm performance, and how well the content of the collection is selected, represented, organized, and managed. xie (2008) focused on user-centered evaluation and found five general criteria that exemplified users’ own evaluations of digital libraries: interface usability, collection quality, service quality, system performance, and user satisfaction. parandjuk (2010) used information architecture to construct criteria for the evaluation of a digital library, including the following: • uniformity of standards, including consistency among webpages and individual records; • findability, including ease of use and multiple ways to access the same information; • sub-navigation, including indexes, sitemaps, and guides; 3see http://www.3dencounters.com. http://www.3dencounters.com/ let’s get virtual: examination of best practices to provide public access to digital versions of three-dimensional objects | johnson | doi:10.6017/ital.v35i2.9343 46 • contextual navigation, including simplified searching and co-location of different types of resources; • language, including consistency in labeling across pages and records and appropriateness for the audience; and • integration of searching and browsing. this system is particularly appropriate in the context of digital museums, as it emphasizes the curatorial or organizational aspect of the collection in order to support learning objectives. in one comprehensive evaluation of the websites of art museums, pallas and economides (2008) created a framework for such evaluation, incorporating six dimensions: content, presentation, usability, interactivity and feedback, e-services, and technical. each dimension then contained several specific criteria. many of the criteria overlapped, however, and three-dimensional imaging, for example, was placed within the e-services dimension, under virtual tours, although it could have been placed within presentation, with other multimedia criteria, or even within interactivity, with interactive multimedia applications. the problem in trying to evaluate a particular part of a museum’s website, namely, the way it presents three-dimensional objects in digital form, is that the level of specificity almost renders many of the evaluation criteria from previous studies irrelevant. as hariri and norouzi (2011) suggest, evaluation criteria should be based on the objective of the evaluation. hence, based on portions of the above-referenced studies, this author has created a more focused evaluation framework, concentrating on criteria that are particularly relevant to museums’ digital presentations of three-dimensional objects. this framework is detailed in table 2, below. dimension description functionality what technology is used to display the object? how well does it work? must programs or files be downloaded? are the loading times of displays acceptable? usability how easy is the site to use? what is the navigation system? are there searching and browsing functions, and how well does each work? how findable are individual objects? presentation how does the display of the object look? what is the context in which the object is presented? are there multiple viewing options? is there any interactivity permitted? content does the site provide an adequate collection of objects? for individual objects, is there sufficient information provided? is there additional educational content? table 2. summary of evaluative criteria five digital collections, specified below, will be evaluated based on these criteria. this will be done in a case study manner, describing each website based on the above criteria and then using those evaluations to make suggestions for best practices. results information technology and libraries | june 2016 47 it is difficult to compare different types of digital collections, particularly when the focus is on different types of technology utilized to display similar objects. however, because the goal here is to determine the best practices for the digital presentation of three-dimensional objects, it is important to evaluate a variety of techniques in a variety of fields. thus, the following digital collections have been chosen to illustrate different ways in which such objects can be displayed on a website. museum of fine arts, boston (mfa) (http://www.mfa.org/collections) the mfa, both in person and online, boasts a comprehensive and extensive collection of art and historical artifacts of varying forms. the website is very easy to navigate, with well-defined browsing options and easy search capabilities, allowing for refinement of results by collection or type of item. there are many collections, which are well organized and curated into separate exhibits and galleries. in addition, when viewing each gallery, suggestions are linked for related online exhibitions as well as tours and exhibits at the physical museum. each item record contains a detailed description of the item as well as its provenance. thus, the mfa website attains a very high rating for usability and content. however, individual items are represented by only single pictures of varying quality. some pictures are color, some are black and white, and no two pictures appear to have the same lighting. additionally, despite being slow to load, even the pictures that appear to be of the best quality cannot be of high resolution, as zooming in makes them slightly blurry. accordingly, the mfa website receives a medium rating for functionality and a low rating for presentation. digital fish library (dfl) (http://www.digitalfishlibrary.org/index.php) the dfl project is a comprehensive program that utilizes mri scanning to digitize preserved biological fish samples from a particular collection housed at the scripps institution of oceanography. after mri scans of a specimen are taken, the data is processed and translated into various views that are placed on the website, accompanied by information about each species (berquist et al. 2012). navigating the dfl website is very intuitive, as the individual specimen records are organized by taxonomy. it is easy to search for particular species or browse through the clickable, pictorial interface. records for each species include detailed information about the individual specimen, the specifics of the scans used to image each, and broader information about the species. individual records also provide links to other species within the taxonomic family. thus, the dfl website attains high ratings in both usability and content. for functionality and presentation, however, the ratings are medium. although for each item there are videos and still images obtained from threedimensional volume renderings and mri scans, they are small in size and have low resolution. there is no interactive component, with the possible exception of the “digital fish viewer” that supposedly requires java, but this author could not get it to work despite best efforts. one nice feature, shown in figure 1 below, is that some of the specimen records have three-dimensional renderings showing and explaining the internal structures of the species. http://www.mfa.org/collections http://www.digitalfishlibrary.org/index.php let’s get virtual: examination of best practices to provide public access to digital versions of three-dimensional objects | johnson | doi:10.6017/ital.v35i2.9343 48 figure 1. annotated three-dimensional rendering of internal structures of hammerhead shark, from the digital fish library (http://www.digitalfishlibrary.org/library/viewimage.php?id=2851) the eton myers collection (http://etonmyers.bham.ac.uk/3d-models.html) the eton myers collection of ancient egyptian art is housed at eton college, and a project to threedimensionally digitize the items for public access was undertaken via collaboration between that institution and the university of birmingham. digitization was accomplished with threedimensional laser scanners, data was then processed with geomagic software to produce point cloud and mesh forms, and individual datasets were reduced in size and converted into an appropriate file type to allow for public access (chapman, gaffney, and moulden 2010). usability of the eton myers collection website is extremely low. the initial interface is simply a list of three-dimensional models by item number with a description of how to download the appropriate program and files. another website from the university of birmingham (http://mimsy.bham.ac.uk/info.php?f=option8&type=browse&t=objects&s=the+eton+myers+col lection) contains a more museum-like interface, but contains many more records for objects than are contained on the initial list of three-dimensional models. moreover, most of the records do not even include pictures of the items, let alone links to the three-dimensional models, and the records that do include pictures do not necessarily include such links. even when a record has a link to the three-dimensional model, it actually redirects to the full list of models rather than to the individual item. there is no search functionality from the initial list of three-dimensional models, and no way to browse other than to, colloquially speaking, poke and hope. individual items are only identified by item number, and, aside from the few records that have accompanying pictures on the university of birmingham site, there is no way to know to what item any given number refers. the http://www.digitalfishlibrary.org/library/viewimage.php?id=2851 http://etonmyers.bham.ac.uk/3d-models.html http://mimsy.bham.ac.uk/info.php?f=option8&type=browse&t=objects&s=the+eton+myers+collection http://mimsy.bham.ac.uk/info.php?f=option8&type=browse&t=objects&s=the+eton+myers+collection information technology and libraries | june 2016 49 website attains only a low rating for content; although it seems that there may be a decent number of items in the collection, it is impossible to know for certain given the problems with the interface and the fact that individual items are virtually unidentified. the eton myers collection website also receives a low rating for functionality. in order to access three-dimensional models of items, users must download and install a program called meshlab, then download individual folders of compressed files, then unzip those files, and finally open the appropriate file in meshlab. despite compression, some of the file folders are still quite large and take some time to download. presentation of the items is also rated low. even for the high resolution versions of the three-dimensional renderings, viewed in meshlab, the geometry of the objects seems underdeveloped (e.g., hieroglyphics are illegible) and surface textures are not well mapped (e.g., colors are completely off). this is evident from a comparison of the threedimensional rendering with a two-dimensional photograph of the same item, as in figure 2, below. figure 2. comparison of original photograph (left) and three-dimensional rendering (right) of item number ecm 361, from the eton myers collection (http://mimsy.bham.ac.uk/detail.php?t=objects&type=ext&f=&s=&record=0&id_number=ecm+3 61&op-earliest_year=%3d&op-latest_year=%3d). notably, chapman, gaffney, and moulden (2010) indicate that the detailed three-dimensional imaging enabled them to identify tooling marks and read previously unclear hieroglyphics on certain items. thus, it is possible that the problems with the renderings may be a result of a loss in quality between the original models and the downloaded versions, particularly given that the files were reduced in size and converted prior to being made available for download.

to digital versions of three-dimensional objects | johnson | doi:10.6017/ital.v35i2.9343 50 epigraphia 3d project (http://www.epigraphia3d.es) the epigraphia 3d project was created to present an online collection of various historical roman epigraphs (also known as inscriptions) that were discovered and excavated in spain and italy; the physical collection is housed at the museo arqueológico nacional (madrid). digital imaging was accomplished using photogrammetry, free software was utilized to create three-dimensional object models and renderings, and photoshop was used to obtain appropriate textures. finally, the three-dimensional model was published on the web using sketchfab, a web service similar to flickr that allows in-browser viewing of three-dimensional renderings in many different formats (ramírez-sánchez et al. 2014). the epigraphia 3d website is intuitive and informative. browsing is simple because there are not many records, but, although it is possible to search the website, there is no search function specifically directed to the collection. thus, usability is rated as medium. despite the fact that the website provides descriptions of the project and the collection, as well as information about epigraphs generally, the website attains a medium rating for content in light of the small size of the collection and the limited information given for each individual item. however, the epigraphia 3d website receives very high ratings for functionality and presentation. the individual threedimensional models are detailed, legible, and interactive. individual inscriptions are transcribed for each item. the use of sketchfab to display the models is effective; no downloading is necessary, and it takes an acceptable amount of time to load. when viewing the item, users can rotate the object in either “orbit” or “first person” mode, as well as view it full-screen or within the browser window. users can also display the wireframe model and the textured or surfaced rendering, as shown in figure 3 below. figure 3. three-dimensional textured (left) and wireframe (middle) renderings from the epigraphia 3d project

smithsonian x 3d project, although affiliated with all of the smithsonian’s varying divisions, was created to test the application of three-dimensional digitization techniques to “iconic collection objects” (http://3d.si.edu/about). the website provides significant detail concerning the project itself, mostly in the form of videos, and individual items, many of which are linked to “tours” that incorporate a story about the object. content is rated as medium because, despite the depth of information provided about individual items, there are still very few items within the collection. the website also receives a medium rating for usability, given the simple browsing structure, easy navigation, and lack of a search feature (all likely due at least in part to the limited content). functionality and presentation, however, are rated high. the x3d explorer in-browser software (powered by autodesk) does more than simply display a three-dimensional rendering of an object; it also permits users to edit the model by changing color, lighting, texture, and other variables as well as incorporates detailed information about each item, both as an overall description and as a slide show, where snippets of information are connected to specific views of the item. the individual three-dimensional models are high resolution, detailed, and wellrendered, with very good surface texture mapping. however, it must be noted that the x3d explorer tool is in beta and, as such, still has some bugs; for example, this author has observed a model disappear while zooming in on the rendering. table 3, below, summarizes the results of the evaluation. functionality usability presentation content mfa medium very high low very high dfl medium high medium high eton myers low low low low epigraphia 3d very high medium very high medium smithsonian x 3d high medium high medium table 3. summary of evaluation results for each website by individual criteria discussion based on the evaluation of the five websites described above, some suggested best practices for the digitization and presentation of three-dimensional objects become apparent. when digitizing, the museum should utilize the method that best suits the object or collection. for example, while mri scanning is likely the best method for three-dimensionally digitizing biological fish specimens, it is not going to be effective or feasible for digitizing artwork or artifacts (abel et al. 2011; berquist et al. 2012). regardless of the method of digitization used, however, the people conducting the imaging and processing should fully comprehend the hardware and software necessary to complete the task. additionally, although financial restraints must be considered, museums should note that some three-dimensional scanning equipment is just as economically feasible as standard digital cameras (metallo and rossi 2011). however, if a museum chooses to utilize only two-dimensional imaging, http://3d.si.edu/ http://3d.si.edu/about let’s get virtual: examination of best practices to provide public access to digital versions of three-dimensional objects | johnson | doi:10.6017/ital.v35i2.9343 52 each item should be photographed from multiple angles in high resolution, to avoid creating a website, like the mfa’s, on which everything other than the object itself is presented outstandingly. further, museums deciding on two-dimensional imaging should explore the possibility of utilizing photogrammetry to create three-dimensional models from their twodimensional photographs, like the epigraphia 3d project. there is free or inexpensive software that functions to permit the creation of three-dimensional object maps from very few photographs (ramírez-sánchez et al. 2014). finally, compatibility is a key issue when conducting threedimensional scans; the museum should ensure that the software used for rendering models is compatible with the way in which users will be viewing the models. in the context of public access to the museum’s digital collections, the website should be easy and intuitive to navigate. the mfa website is an excellent example; browsing and search functions should both be present, and reorganization of large numbers of objects into separate collections may be necessary. where searching is going to be the primary point of entry into the collection, it is important to have sufficient metadata and functional search algorithms to ensure that item records are findable. furthermore, remember that the website is simply a way to access the museum itself. hence, the collections on the website, like the collections in the physical museum, should be curated; there should be a logical flow to accessing object records. the museum may also want to have sections that are similar to virtual exhibitions, like the “tours” provided by the smithsonian x 3d project. finally, museums should ensure that no additional technological know-how (beyond being able to access the internet) is required to access the three-dimensional content in object records. users should not be required to download software or files to view records; epigraphia 3d’s use of sketchfab and the smithsonian’s x 3d explorer tool are both excellent examples of ways in which three-dimensional content can be viewed on the web without the need for extraneous software. museums and cultural heritage institutions are increasing the focus on providing public access to collections via digitization and display on websites (given and mctavish 2010). in order to do this effectively, this paper has attempted to provide some guidance as to best practices of presenting digital versions of three-dimensional objects. in closing, however, it must be noted that this author is not a technician. although this paper has tried to contend with the issues from the perspective of a librarian, there are complicated technical concerns behind any digitization project that have not been adequately addressed. in addition, this paper has not examined the role of budgetary constraints on digitization or the concomitant issues of creating and maintaining websites. moreover, because this paper has been treated as a broad overview of the digitization and presentation for public access of three-dimensional objects, the five websites evaluated were from varying fields of study. museums should look to more specific comparisons in order to appropriately digitize and present their collections on the web. conclusion there may not be a direct substitute for encountering an object in person, but for people who cannot obtain physical access to three-dimensional objects, the digital realm can serve as an adequate proxy. this paper has demonstrated, through an evaluation of five distinct digital collections, that utilizing three-dimensional imaging and presenting three-dimensional models of physical objects on the web can serve the important purpose of increasing public access to otherwise unavailable collections. information technology and libraries | june 2016 53 references abate, d., r. ciavarella, g. furini, g. guarnieri, s. migliori, and s. pierattini. “3d

makerspaces at new england college and research libraries ann marie l. davis information technology and libraries | june 2018 94 ann marie l. davis (davis.5257@osu.edu) is faculty librarian of japanese studies at the ohio state university. abstract this study investigates why and which types of college and research libraries (crls) are currently developing makerspaces (or an equivalent space) for their communities. based on an online survey and phone interviews with a sample population of crls in new england, i found that 26 crls had or were in the process of developing a makerspace in this region. in addition, several other crls were actively promoting and diffusing the maker ethos. of these libraries, most were motivated to promote open access to new technologies, literacies, and stem-related knowledge. introduction and overview makerspaces, alternatively known as hackerspaces, tech shops, and fab labs, are trendy new sites where people of all ages and backgrounds gather to experiment and learn. born of a global community movement, makerspaces bring the do-it-yourself (diy) approach to communities of tinkerers using technologies including 3d printers, robotics, metaland woodworking, and arts and crafts.1 building on this philosophy of shared discovery, public libraries have been creating free programs and open makerspaces since 2011.2 given their potential for community engagement, college and research libraries (crls) have also been joining the movement in growing numbers.3 in recent years, makerspaces in crls have generated positive press in popular and academic journals. despite the optimism, scholarly research that measures their impact is sparse. for example, current library and information science literature overlooks why and how various crls choose to create and maintain their respective makerspace. likewise, there is scant data on the institutional objectives, frameworks, and experiences that characterize current crl makerspace initiatives.4 this study begins to fill this gap by investigating why and which types of crls are creating makerspaces (or an equivalent room or space) for their library communities. specifically, it focuses on libraries at four-year colleges and research universities in new england. throughout this study, makerspace is used interchangeably with other terms, including maker labs and innovation spaces, to reflect the variation in names and objectives that underlie the current trends. in exploring their motives and experiences, this article provides a snapshot of the current makerspace movement in crls. mailto:davis.5257@osu.edu current trends and goals in the development of makerspaces | davis 95 https://doi.org/10.6017/ital.v37i2.9825 the study finds that the number of crls actively involved in the makerspace movement is growing. in addition to more than two dozen that have or are in the process of developing a makerspace, another dozen crls have staff who support the diffusion of maker technologies, such as 3d printing and crafting tools that support active learning and discovery, in the campus library and beyond.5 comprising research and liberal arts schools, public and private, and small and large, the crls involved with makerspaces are strikingly diverse. despite these differences, this population is united by common objectives to promote new literacies, provide open access to new technologies, and foster a cooperative ethos of making. literature review the body of literature on library makerspaces is brief, descriptive, and often didactic. given the newness of the maker movement in public and academic libraries, many articles focus on early success stories and defining the movement vis-à-vis the mission of the library. for instance, laura britton, known for having created the first makerspace in a public library (the fayetteville free library’s fabulous laboratory), defines a makerspace as “a place where people come together to create and collaborate, to share resources, knowledge, and stuff.”6 this definition, she determines, is strikingly similar to that of the library. most literature on makerspaces appears in academic blogs, professional websites, and popular magazines. among the most frequently cited is tj mccue’s article, which celebrates britton’s (née smedley) fablab while distilling the intellectual underpinnings of the makerspace ethos.7 phillip torrone, editor of make: magazine, supports smedley’s project as an example of “rebuilding” or “retooling” our public spaces.8 within this camp, david lankes, professor of information studies at syracuse university, applauds such work as activist and community-oriented librarianship.9 many authors emphasize the philosophical “fit,” or intersection, of public makerspaces with the principles of librarianship. building on torrone’s work, j. l. balas claims that creating access to resources for learning and making is in keeping with the “library’s historical role of providing access to the ‘tools of knowledge.’”10 others emphasize the hands-on, participatory, and intergenerational features of the maker movement, which has the potential to bridge the digital divide.11 still others identify areas of literacy, innovation, and ste(a)m skills where library makerspaces can have a broad impact. while public libraries often focus on early childhood or adult education, crls adopt separate frameworks for information literacy. like public libraries, they aim to build (meta)literacies and ste(a)m skills. nevertheless, their programs often tailor to curricular goals in the arts and sciences or specialized degrees in engineering, education, and business. this is especially true of crls situated within large, research-intensive universities. considering their specific missions and aims, this study seeks to identify the goals and challenges that reinforce the development of makerspaces in undergraduate and research environments. research design and method data presented in this study was gathered from library directors (or their designees) through an online survey and oral telephone interviews. after choosing a sampling frame of crls in new england, i developed a three-path survey, sent invitations, and collected and analyzed data using the online platform surveymonkey. the survey was distributed following review by the information technology and libraries | june 2018 96 institutional review board (irb) at southern connecticut state university, where i completed a master of library science (mls) degree. survey population to assess generalized findings for the larger population in north america, i chose a clustersampling approach that limited the survey population to the crls in new england. in generating the sampling frame, i included four-year and advanced-degree institutions based on the assumption that libraries at these schools supported specialized, research, or field-specific degrees. i omitted for-profit and two-year institutions, based on the assumption that they are driven by separate business models. this process generated a contact list of 182 library directors at the designated crls in connecticut, maine, massachusetts, new hampshire, rhode island, and vermont. survey design the purpose of the survey was to gather basic data about the size and structure of the respondents’ institutions and to gain insights on their views and practices regarding makerspaces (the survey is reproduced in the appendix). the first page of the survey contained a statement of consent, including my contact information and that of my irb. after a short set of preliminary questions, the survey branched into one of three paths based on respondents’ answers about makerspaces. the respondents were thus categorized into one of three groups: path one (p1) for those with no makerspace and no plans to create one, path two (p2) for those with plans to develop a makerspace in the near future, and path three (p3) for those already running a makerspace in their libraries. p3 was the longest section of the survey, containing several questions about p3 experiences with makerspaces such as staffing, programing, and objectives. data collection in summer 2015, brief email invitations and two reminders were sent to the targeted population.12 to increase the participation rate, i sometimes wrote personal emails and made direct phone calls to crls known to have makerspace. for cold-call interviews, i developed a script explaining the nature of the online survey. after obtaining informed consent, i proceeded to ask the questions in the online survey and manually enter the participants’ responses at the time of the interview. on a few occasions, online respondents followed up with personal emails volunteering to discuss their library’s experiences in more detail. i took advantage of these invitations, which often provided unique and welcome insights. in analyzing the responses, i used tabulated frequencies for quantitative results and sorted qualitative data into two different categories. the first category was identified as “short and objective” and coded and analyzed numerically. the longer, more “subjective and value-driven” data was analyzed for common trends, relationships, and patterns. within this second category, i also identified outlier responses that suggested possible exceptions to common experiences. results the survey closed after one month of data collection. at this time, 55 of 182 potential respondents had participated, yielding a response rate of 30.2%. among these participants, the survey achieved a 100.0% response rate (9 completed surveys of 9 targeted crls) among libraries that were current trends and goals in the development of makerspaces | davis 97 https://doi.org/10.6017/ital.v37i2.9825 currently operating makerspaces. i created a list of all known crl makerspaces in new england based on an exhaustive

respondents, 29 (52.7%) were in p1, 17 (30.9%) were in p2, and 9 (16.4%) were in p3. (see figure 1.) figure 1. survey participants’ (n = 55) current crl efforts and plans to develop and operate a makerspace. among respondents in p2 and p3, the majority (13 of 23) indicated that they were from libraries that served a student population of 4,999 people or fewer, while only one library served a population of 30,000 or more (see figure 2). in terms of sheer numbers, makerspaces might seem to be gaining traction at smaller crls, but proportionally, one cannot say that smaller crls are adopting makerspaces at a higher rate because the majority of survey participants have student populations of 19,999 or less (51, or 91.1%). the number of institutions with populations over 20,000 were in a clear minority (5, or 8.9%).

of makerspaces | davis 99 https://doi.org/10.6017/ital.v37i2.9825 crls with no makerspace (p1 = 29) in the first part of the survey, the majority of p1 respondents demonstrated positive views toward makerspaces despite having no plans to create one in the near future. budgetary and space limitations aside, many were relatively open to the possibility of developing a makerspace in a more distant future. in the words of one respondent, “we have several areas within the library that present a heavy demand on our budget. in [the] future, we would love to consider a makerspace, and whether it would be a sensible and appropriate investment that would benefit our students.” when asked what their reasons were for not having a makerspace, some respondents (8, or 27.6%) said they had not given it much thought, but most (21, or 72.4%) offered specific answers. among these, the most frequently cited reason (11, or 37.8%) was that a library makerspace would be redundant: such spaces and labs were already offered in other departments within the institution or in the broader community. at one crl, for example, the respondent said the library did not want to compete with faculty initiatives elsewhere on campus. other reasons included that makerspaces were expensive and not a priority. some (5, or 17.2%) libraries preferred to allocate their funds to different types of spaces such as “a very good book arts studio/workshop” or “simulation labs.” some (6, or 20.6%) shared concerns about a lack of space, staff, or simply “a good culture of collaboration [on campus].” merging these sentiments, one respondent concluded, “people still need the library to be fairly quiet. . . . having makerspace equipment in our library would be too distracting.” while some were skeptical (sharing concerns about potential hazards or that makerspaces were simply “the flavor of the month”), the majority (roughly 60%) were open and enthusiastic. one respondent, in fact, held a leadership position in a community makerspace beyond campus. according to this librarian, 3d printers, scanners, and laser cutters were sure to become more common, and crls would no doubt eventually develop “a formal space for making stuff.” crls with plans for a makerspace in the near future (p2 = 17) the second section of the survey (p2) focused primarily on the motivations and means by which this cohort planned to develop a makerspace. when asked why they were creating a makerspace, the most common response was to promote learning and literacy (15 respondents, or 88.2%). in addition, a large majority (12 respondents, or 70.6%) felt that makerspaces helped to promote the library as relevant, particularly in the digital age. three more reasons that earned top scores (10 respondents each, or 58.2%) were being inspired by the ethos of making, creating a complement to digital repositories and scholarship initiatives, and providing access to expensive machines or tools. additional reasons included building outreach and responding to community requests.13 (see figure 4.) information technology and libraries | june 2018 100 figure 4. rationale behind p2 respondents’ decision to plan a makerspace (n = 17). while p2 respondents indicated a clear decision to create a makerspace, their timeframes were noticeably different. i categorized their open responses into one of six timeframes: “within six months,” “within one year,” “within two years,” “within four years,” “within six years,” and “unknown.” the result presented a clear trimodal distribution with three subgroups: six crls with plans to open within 18 months, five with plans to open within the next two years, and six with plans to open after three or more years (see figure 5). in addition to their timeframe, p2 respondents were also asked about their plans for financing their future makerspaces. based on their open responses, the following six funding sources emerged: • the library budget, including surplus moneys or capital project funds • internal funding, including from campus constituents • donations and gifts • external grants • cost recovery plans, including small charges to users • not sure/in progress current trends and goals in the development of makerspaces | davis 101 https://doi.org/10.6017/ital.v37i2.9825 figure 5. p2 respondents’ timeframe for developing the makerspace (n = 17). with seven mentions, the most common of the above funding was the “library budget.” with two mentions each, the least common sources were “cost recovery” and “not sure/in progress.” among those who mentioned external grant applications, one respondent mentioned a focus on women and stem opportunities, and another specifically discussed attempts at grants from the institute of museum and library services. (see figure 6.) figure 6. p2respondents’ plans for gathering and financing makerspace (n = 17). regarding target user groups, some respondents focused on opportunities to enhance specific disciplinary knowledge, while others emphasized a general need for creating a free and open environment. one respondent mentioned that at her state-funded library, the space would be “geared to younger [primary and secondary school] ages,” “student teachers,” and “librarians on practicum assignments.” by contrast, another respondent at a large, private, carnegie r1 information technology and libraries | june 2018 102 university emphasized that the space was earmarked for the undergraduate and graduate students. in contrast to the cohort in p1, a notable number in p2 chose to create a makerspace despite the existence of maker-oriented research labs elsewhere on campus. as one respondent noted, the university was still “lacking a physical space where people could transition between technologies” and an open environment “where students doing projects for faculty” could come, especially later in the evenings. another respondent at a similarly large, private institution explained that his colleagues recognized that most labs at their university were earmarked for specific professional schools. as a result, his colleagues came up with a strategy to provide self-service 3d printing stations at the media center, located in the library at the heart of campus. crls with operating makerspaces (p3 = 9) the final section of the survey (p3) focused on the motivations and means by which crls with makerspaces already in operation chose to develop and maintain their sites. in addition, this section gathered information on p3 crl funding decisions, service models, and types of users in their makerspaces. of the nine respondents in this path, all had makerspaces that had opened within the last three years. among these, roughly a third (4) had been in operation from one to two years; another third (3) had operated for two to three years; and two had opened within the last year. (see table 1.) table 1. length of time the crl makerspace has been in operation for p3 respondents (n = 9). age of crl makerspace or lab—p3 answer options responses % less than 6 months 1 11.1 6–12 months 1 11.1 1–2 years 4 44.4 2–3 years 3 33.3 more than 3 years 0 0.0 total responses 9 100.0 priorities and rationale the reasons behind p3 decisions to make a makerspace were slightly different from those of p2. while “promoting literacy and learning” was still a top priority, two other reasons, “promoting the maker culture of making” and “providing access to expensive machinery,” were deemed equally important (6 respondents, or 66.7%, for each). other significant priorities included “promoting community outreach” (4 respondents, or 44.4%), “promoting the library as relevant” and in “direct response to community requests” (3 respondents, or 33.3%, for each). (see figure 7.) current trends and goals in the development of makerspaces | davis 103 https://doi.org/10.6017/ital.v37i2.9825 figure 7. rationale behind p3 respondents’ decision to develop and maintain a makerspace (n = 9). the answer of “other” was also given top priority (5 respondents, or 55.6%). i conclude that this indicated a strong desire among respondents to express in their own words their library’s unique decisions and circumstances. (their free responses to this question are discussed below.) a familiar theme in the responses of the five respondents who elaborated on their choice of “other” was the desire to situate a makerspace in the central and open environment of the campus library. as one participant noted, there were “other access points and labs on campus,” but those labs were “more siloed” or cut off from the general population. by contrast, the campus library aimed to serve a broader population and anticipated a general “student need.” later, the same respondent added that the makerspace was an opportunity to promote social justice, cultivate student clubs, and encourage engagement at the hub of the campus community. this type of ecumenical thinking was manifested in a similar remark that the library’s role was to reinforce other learning environments on campus. one respondent saw the makerspace as an additional resource “that complemented the maker opportunities that we have had in our curriculum resource center for decades.” likewise, the library makerspace was intended to offer opportunities to a range of users on campus and beyond. funding, staffing, and service models when prompted to discuss how they gathered the resources for their makerspaces, the largest group (4 respondents) stated that a significant means for funding was through gifts and donations. thus, the majority of crl makerspaces in new england depended primarily on contributions from friends of the library, university/college alumni, and donors. the second most common source (3 respondents) was through the library budget, including surplus money at the end of the year. making use of grant money and cost recovery were mentioned by two library participants, and internal and constituent support was useful for two libraries. (see figure 8.) information technology and libraries | june 2018 104 figure 8. p3 methods for gathering and financing a makerspace (n = 9). among these, a particularly noteworthy case was a makerspace that had originated from a new student club focused on 3d printing. originally based in a student dorm, the club was funded by a campus student union, which allocated grant money to students through a budget derived from the college tuition. as the club quickly grew, it found significant support in the library, which subsequently provided space (on the top floor of the library), staff, and financial support from surplus funds in the library budget. as this example would suggest, the sum of the responses showed that financing the makerspaces depended on a combination of strategies. one participant summarized it best: “we’ve slowly accumulated resources over time, using different funding for different pieces. some grant funding. mostly annual budget.” regarding service models, more than half of these libraries (five) currently offer a combination of programming and open lab time where users could make appointments or just drop in. by contrast, two of the libraries offered programs only, and did not offer an open lab; another two did the opposite, offering no programming but an open makerspace at designated times. of the latter, one is open monday to friday from 8 a.m. to 4 p.m., and the other is open during regular hours, with spaces that “can be booked ahead for classes or projects.” most labs supported drop-in visitors and were open evenings and weekends. at one makerspace, where there was increasingly heavy demand, the staff required students to submit proposals with project goals. (see table 2.) while some libraries brought in community experts, others held faculty programs, and some scheduled lab time for individual classes. one makerspace prioritized not only the campus, but also the broader community, and thus featured programs for local high schools and seniors. responses from this library emphasized the social justice thread that inspired their work and the community culture that they aimed to foster. current trends and goals in the development of makerspaces | davis 105 https://doi.org/10.6017/ital.v37i2.9825 table 2. model for services offered in the crl makerspace or 3d printing lab do you offer programs in the makerspace/lab or is it simply opened at defined times for users to use? answer options responses % yes, we offer the following types of programs. 2 22.2 no, we simply leave the makerspace/lab open at the specific times. 2 22.2 we do both. we offer the programs and leave the makerspace/lab open at specific times. 5 55.6 as this data would suggest, most makerspaces were used by students (undergraduates and graduates) and faculty, in addition to local experts and generational groups. survey responses showed that undergraduate students were the most common users (9 of 9 respondents checked this group as the most frequent type of user), and faculty and graduate students were the second and third most common (8 of 9 respondents checked these groups as most frequent) user groups in the labs. local entrepreneurs, artists, designers, craftspeople, and campus and library staff also use the makerspaces. (see figure 9.) when prompted to identify “other” categories, one respondent specifically listed “learners, makers, sharers, studiers, [and] clubs.” figure 9. of the different types of users listed above, p3 respondents ranked them in order of who used the makerspace or equivalent lab most often (n = 9). the number and type of staff that managed and operated the makerspaces also varied widely at the nine crls in p3. seven of the crls employed full-time, dedicated staff, among whom four participants checked off the “dedicated staff”–only options. of the remaining two crls, one information technology and libraries | june 2018 106 reported staffing the makerspace with only one student, and one reported not having any staff working in the makerspace. i assume that the makerspace with no employees is managed by staff and students who are assigned to other, unspecified library departments or work groups. (see figure 10.) figure 10. the staffing situations at the p3 respondents (n = 9), where each respondent is assigned a letter from “a” to “i.” library programing was also diverse in terms of targeted audiences, speakers, and learning objectives. instructional workshops varied from 3d scanning and printing to soldering, felt making, sewing, knitting, robotics, and programming (e.g., raspberry pi.) the type of equipment contained in each lab is likely correlated to the range in programming; however, investigating these links was beyond the scope of this study. regarding this equipment, the size and activity of the participant crls varied considerably. some responses were more specific than others, and thus the resulting dataset was incomplete (see table 3.) challenges and philosophies of crl makerspaces the final portion of the survey invited participants to freely offer their thoughts about operating a crl makerspace. what follows below is a summary of the two most prominent themes that emerged: the challenges of building the lab and the social philosophies that framed these initiatives. in terms of challenges, the most common hurdle noted was the tremendous learning curve involved in establishing, maintaining, and promoting a makerspace. setting up some of the 3d printers, for example, required knowledge about electrical networks, computer systems, and safety policies at a federal and local level. once the hardware was running, lab managers needed to know how the machines interfaced with different and challenging software applications. communication skills were also critical, as one respondent reported, “printing anything and everything takes knowledge, experience.” communicating with stakeholders and users in accessible and proactive ways required strong teaching and customer service skills. current trends and goals in the development of makerspaces | davis 107 https://doi.org/10.6017/ital.v37i2.9825 table 3. the types of tools and equipment used at

resources at other labs on campus) another challenge that often came up was that of managing resources. as one respondent warned, crls should beware the “early adoption of certain technologies,” which can become “quickly information technology and libraries | june 2018 108 outdated by a rapidly growing field.” for others, it was a challenge to recruit the right staff that could run and fix machines in constant need of repair. in addition to hiring people with manufacturing and teaching skills, a successful lab required individuals who were savvy about outreach and community needs. despite such challenges, many respondents were eager to discuss the aspirations and rewards of crl makerspaces. above all, respondents focused on the pedagogical opportunities on the one hand, and the potential for outreach and social justice on the other. one participant conceded that measuring advances in literacy and education was “intangible,” but he saw great value in “giving students the experience of seeing their ideas come to fruition.” the excitement that this created for one student manifested in a buzz, and subsequently a “fever” or groundswell, in which more users came in to tinker and learn. meanwhile, the learning that took place among future professionals on campus was “critical,” even when results did not “go viral.” the aspiration to create human connections within and beyond campus was another striking theme. according to one respondent, the makerspace had “enabled some incredibly fruitful collaborations with different departments on campus.” this “fantastic outcome” was becoming more and more visible as the maker community grew. other crl makerspaces took pride in fostering a type of learning that was explicitly collaborative, exciting, and even “fun” for users. this in turn meant that some libraries were becoming “very popular,” generating a lot of “good pr,” and becoming central in the lives of new types of library users. along these lines, some respondents aimed to leverage the power of the makerspace to achieve social justice goals that resonated with core values of librarianship. according to one enthusiastic participant, the ethos of sharing was alive and strong among the staff and the many students who saw their participation in the lab as a lifestyle and culture of collaborating. in another initiative, the respondent looked forward to eventually offering grants to those users who proposed meaningful ways to use the makerspace to create practical value for the community. from this perspective, there was added value in having the 3d printing lab situated specifically on a college or university campus. according to this respondent, the unique quality of the crl makerspace was that by virtue of its location amid numerous and energetic young people, it was ripe for exploitation by those “who had great ideas and time and energy to do good.” discussion the aim of this study was to explore why and which types of crls had developed makerspaces (or an equivalent space) for their communities. of the 56 respondents, roughly half (46%) were p2 and p3 libraries who were currently developing or operating a makerspace, respectively. data from this survey indicated that none of the p2 or p3 crls fit a mold or pattern in terms of their size, educational models, or classifications. upon analyzing the data, i found that the differentiators between the three groups were less clearly defined than originally anticipated. in one example of blurred lines, at least two respondents in p1 indicated that they were more actively engaged with makerspaces than two respondents in p2. despite not having physical labs within their libraries, these p1 respondents were in the process of actively supporting or making plans for a makerspace within their crl community. one p1 respondent, for example, served on the planning board for a local community makerspace and had therefore “thoroughly investigated and used” the makerspace at a current trends and goals in the development of makerspaces | davis 109 https://doi.org/10.6017/ital.v37i2.9825 neighboring university. based on his knowledge, he decided to develop a complementary initiative (e.g., a book arts workshop) at his university library. although his library did not yet have a formal makerspace, he felt confident that the diffusion of 3d printers would come to his library in the near future. another p1 respondent was responsible for administering faculty teaching and innovation grants. among the recent grant recipients were two faculty collaborators who used the library’s funds to build a makerspace at a campus location that was separate from the library. although the makerspace was not directly developed by the respondent’s library, it was nevertheless a direct product of his library’s programmatic support. the respondent reported that for this reason, his library did not want to compete with its own faculty initiatives. in another example of blurred distinctions, one librarian in p2 was as deeply immersed in providing access and education on makerspaces as his colleagues in p3. although he was not clear on when or how his library would finance a future makerspace, his library already offered many of the same services and workshops as p3 libraries. as a “maker in the library,” he offered noncredit-bearing 3d printing seminars to students and offered trial 3d printing services in the library for graduates of the 3d printing seminar. in addition, he made appearances at relevant campus events. when the university museum ran a 3d printing day, for instance, he participated as an expert panelist and gave public demonstrations on library-owned 3d printers and a scanner kinect bar. in sum, despite the respondents’ categorization in p1 and p2, they sometimes shared more in common with the cohorts in p2 and p3, respectively. given their library’s programmatic involvement in creating and endorsing the maker movement, these respondents were more than just “interested” or “open to” the prospect of creating a makerspace. while only 16% of crls (p3 = 9) responded as actively operating a makerspace, another 30% (p2 = 17) were involved in developing a makerspace in the near future. moreover, the number of crls formally involved with the diffusion of maker technologies was not limited to just these two groups. although some makerspaces were not directly run by the library, they had come to fruition because of librarybased funding, grants, and professional support. and although some libraries did not have immediate plans for a makerspace, they were already promoting maker technologies and the maker ethos in other significant ways. conclusion this study is one of the first comprehensive and comparative studies on crl makerspace programs and their respective goals, policies, and outcomes. while the number of current crl makerspaces is relatively low, the data suggests that the population is increasing; a growing number of crls are involved in the makerspace movement. more than two dozen crls were planning to develop makerspaces in the near future, helping to diffuse maker technologies through crl programming, and/or supporting nonlibrary maker initiatives on campus and beyond. in addition, some crls were buying equipment, hiring dedicated staff, offering relevant workshops and demonstrations, and supporting community efforts to build labs beyond the library. although the author aimed to find structural commonalities between crls in groups p2 and p3, none were found. respondents in these groups came from institutions of all sizes , a wide variety information technology and libraries | june 2018 110 of endowment levels, and both public and private funding models, and they ranged in emphasis from the liberal arts to professional certifications and graduate-level research. although a majority of crl respondents were not currently making plans to create a makerspace, many respondents were enthusiastic about current trends, and some even promoted the maker movement in unexpected ways. acknowledging the steady diffusion of 3d printers, many anticipated using such technologies in the future to promote traditional library values and goals. respondents in p2 and p3 indicated that their primary rationale for developing a makerspace was to promote learning and literacy. other prominent reasons included promoting library outreach and the maker culture of learning. data from crls with makerspaces indicated that these benefits were often symbiotic and correlated to strong ideas about universal access to emergent tools and practices in learning. unexpected challenges for developing and operating makerspaces include staffing them with highly skilled, knowledgeable, and service-oriented employees. learning the necessary skills— including operating the printers, troubleshooting models, and maintaining a safe environment, to name a few—was time-consuming and labor intensive. the majority of funding for crls with or planning maker labs came from internal budgets, gifts and donors, and some grants. while some p1 crls indicated that their reason for not developing makerspaces was a lack of community interest, p2 and p3 crls were not necessarily motivated by user requests or needs, nor was lack of explicit need or interest a deterrent. on the contrary, a few reported a desire to promote the campus library as ahead of the curve by keeping in front of student and community needs. in a similar contradiction, some p1 respondents reported that their libraries did not want to compete with other labs on campus. respondents from p2 and p3, however, wanted to offer an alternative to the more siloed or structured model of departmentor lab-funded makerspaces. although makerspaces were sometimes forming in other parts of campus, some p2 and p3 crls felt there was a gap in accessibility and therefore aimed to offer more open and flexible spaces. a final salient theme among p2 and p3 respondents was their commitment to equity of access and issues of social justice. above all, they saw a unique fit for makerspaces in their crl philosophies to serve the greater good. among other advantages, crls were in a unique position to leverage the power of the makerspaces to take advantage of campus communities of “cognitive surplus” and millennial aspirations to share and create spontaneous communities of knowledge. given the amount of resources that are required to create and maintain a makerspace, this research will be useful for crls considering such a space in the future. the present data suggests that no one type of library currently has a monopoly on maker spaces; regardless of size or funding levels, the common thread among p2 and p3 crls was simply a commitment to providing access to emergent technologies and supporting new literacies. while annual budgets and grant applications were critical for some libraries, the majority of crls funded the bulk of their makerspaces through gifts and donations. future studies on the characteristics and challenges of p2 and p3 populations beyond those in new england will certainly amplify our understanding of these trends. current trends and goals in the development of makerspaces | davis 111 https://doi.org/10.6017/ital.v37i2.9825 appendix: survey

and notes december_ital_fifarek_final president’s message: focus on information ethics aimee fifarek information technologies and libraries | december 2016 1 just a few weeks ago we held yet another successful lita forum1, this time in fort worth, tx. tight travel budgets and time constraints mean that only a few hundred people get to attend forum each year, but that is one of the things that make it a great conference. because of its size you have a realistic chance of meeting everyone there, whether it’s at game night, one of the many networking dinners, or just for during hallway chitchat after a session. and the sessions really do give you something to talk about. this year i couldn’t help but notice a theme. among all the talk about makerspace technologies, analytics, and specific software platforms, the one bubble that kept rising to the surface was information ethics. why are you doing what you are doing with the information you have, and should you really be doing it? have you stopped to think what impact collecting, posting, sharing that information is going to have on the world around you? in a post-election environment replete with talk of fake news and other forms of deliberate misinformation, lita forum presenters seem to have tapped in to the zeitgeist. tara robertson, in her closing keynote2, talked about the harm digitizing analog materials can do when what is depicted is sensitive to individuals and communities. waldo jaquith of us open data talked about how a government decision to limit options on a birth certificate to either “white” or “colored” effectively wiped the native population out of political existence in virginia. and sam kome from claremont colleges talked about how well-meaning librarians can facilitate privacy invasion merely by collecting operational statistics3. there were many other examples brought out by forum speakers but these in particular emphasized the real consequences the serious consequences the use of data – intentional or not – can have on people. i think it is time for librarians4 to get more vocal about information ethics and the role we play in educating the population about humane information use. our profession has always been forward thinking about information literacy and is traditionally known for helping our communities make judgements about the information they consume. but we have not done enough to declare our expertise in the information economy, to stand up and say “we’re librarians – this is what we do.” now, more than ever, people need the skills to think critically about the information they are consuming via all kinds of media, understand the consequences of allowing algorithms to shape their information universe, and make quality judgments about trading their personal information for goods and services. to quote from unesco: aimee fifarek (aimee.fifarek@phoenix.gov) is lita president 2016-17 and deputy director for customer support, it and digital initiatives at phoenix public library, phoenix, az. president’s message | fifarek https://doi.org/10.6017/ital.v35i4.9602 2 changes brought about by the rapid development of information and communication technologies (ict) not only open tremendous opportunities to humankind but also pose unprecedented ethical challenges. ensuring that information society is based upon principles of mutual respect and the observance of human rights is one of the major ethical challenges of the 21st century.5 i challenge all librarians to make a commitment to propagating information ethics, both personally and professionally. make an effort to get out of your social media echo chamber6 and engage with uncomfortable ideas. when you see biased information being shared consider it a “teachable moment” and highlight the spin or present more neutral information. and if your library is not actively making information literacy and information ethics part of its programming and instruction, then do what you can to change it. offer to be on a panel, create a curriculum, or host a program that includes key concepts relating to information “ownership, access, privacy, security, and community”7. the focus of the libraries transform campaign this year is all about our expertise: “because the best search engine in the library is the librarian”8 it’s our time to shine. references 1.

and heidi a. heilemann this paper describes one approach to creating a search application that unlocks heterogeneous content stores and incorporates integrative functionality of web search engines. laneconnex is a search interface that identifies journals, books, databases, calculators, bioinformatics tools, help information, and search hits from more than three hundred full-text heterogeneous clinical and bioresearch sources. the user interface is a simple query box. results are ranked by relevance with options for filtering by content type or expanding to the next most likely set. the system is built using component-oriented programming design. the underlying architecture is built on apache cocoon, java servlets, xml/xslt, sql, and javascript. the system has proven reliable in production, reduced user time spent finding information on the site, and maximized the institutional investment in licensed resources. m ost biomedical libraries separate searching for resources held locally from external database searching, requiring clinicians and researchers to know which interface to use to find a specific type of information. google, amazon, and other web search engines have shaped user behavior and expectations.1 users expect a simple query box with results returned from a broad array of content ranked or categorized appropriately with direct links to content, whether it is an html page, a pdf document, a streaming video, or an image. biomedical libraries have transitioned to digital journals and reference sources, adopted openurl link resolvers, and created institutional repositories. however, students, clinicians, and researchers are hindered from maximizing this content because of proprietary and heterogeneous systems. a strategic challenge for biomedical libraries is to create a unified search for a broad spectrum of licensed, open-access, and institutional content. n background studies show that students and researchers will use the search path of least cognitive resistance.2 ease and speed are the most important factors for using a particular search engine. a university of california report found that academic users want one search tool to cover a wide information universe, multiple formats, full-text availability to move seamlessly to the item itself, intelligent assistance and spelling correction, results sorted in order of relevance, help navigating large retrievals by logical subsetting and customization, and seamless access anytime, anywhere.3 studies of clinicians in the patient-care environment have documented that effort is the most important factor in whether a patient-care question is pursued.4 for researchers, finding and using the best bioinformatics tool is an elusive problem.5 in 2005, the lane medical library and knowledge management center (lane) at the stanford university medical center provided access to an expansive array of licensed, institutional, and open-access digital content in support of research, patient care, and education. like most of its peers, lane users were required to use scores of different interfaces to search external databases and find digital resources. we created a local metasearch application for clinical reference content, but it did not integrate result sets from disparate resources. a review of federated-search software in the marketplace found that products were either slow or they limited retrieval when faced with a broad spectrum of biomedical content. we decided to build on our existing application architecture to create a fast and unified interface. a detailed analysis of lane website-usage logs was conducted before embarking on the creation of the new search application. key points of user failure in the existing search options were spelling errors that could easily be corrected to avoid zero results; lack of sufficient intuitive options to move forward from a zero-results search or change topics without backtracking; lack of use of existing genre or role searches; confusion about when to use the resource, openurl resolver, or pubmed search to find a known item; and results that were cognitively difficult to navigate. studies of the web search engine and the pubmed search log concurred with our usagelog analysis: a single term search is the most common, with three words maximum entered by typical users.6 a pubmed study found that 22 percent of user queries were for known items rather than for a general subject, confirming our own log analysis findings that the majority of searches were for a particular source item.7 search-term analysis revealed that many of our users were entering partial article citations (e.g., author, date) in any query debra s. ketchell (debra.ketchell@gmail.com) is the former associate dean for knowledge management and library director; ryan max steinberg (ryan.max.steinberg@stanford .edu) is the knowledge integration programmer/architect; charles yates (charles.yates@stanford.edu) is the systems software developer; and heidi a. heilemann (heidi.heilemann@stanford .edu) is the former director for research & instruction and current associate dean for knowledge management and library director at the lane medical library & knowledge management center, information resources & technology, stanford university school of medicine, stanford, california. 32 information technology and libraries | march 2009 box expecting that article databases would be searched concurrently with the resource database. our displayed results were sorted alphabetically, and each version of an item was displayed separately. for the user, this meant a cluttered list with redundant title information that increased their cognitive effort to find meaningful items. overall, users were confronted with too many choices upfront and too few options after retrieving results. focus groups of faculty and students were conducted in 2005. attendees wanted local information integrated into the proposed single search. local information included content such as how-to information, expertise, seminars, grand rounds, core lab resources, drug formulary, patient handouts, and clinical calculators. most of this content is restricted to the stanford user population. users consistently described their need for a simple search interface that was fast and customized to the stanford environment. in late 2005, we embarked on a project to design a search application that would address both existing points of failure in the current system and meet the expressed need for a comprehensive discovery-andfinding tool as described in focus groups. the result is an application called laneconnex. n design objectives the overall goal of laneconnex is to create a simple, fast search across multiple licensed, open-access, and special-object local knowledge sources that depackages and reaggregates information on the basis of stanford institutional roles. the content of lane’s digital collection includes forty-five hundred journal titles and fortytwo thousand other digital resources, including video lectures, executable software, patient handouts, bioinformatics tools, and a significant store of digitized historical materials as a result of the google books program. media types include html pages, pdf documents, jpeg images, mp3 audio files, mpeg4 videos, and executable applications. more than three hundred reference titles have been licensed specifically for clinicians at the point of care (e.g., uptodate, emedicine, stat-ref, and micromedex clinical evidence). clinicians wanted their results to reflect subcomponents of a package (e.g., results from the micromedex patient handouts). other clinical content is institutionally managed (e.g., institutional formulary, lab test database, or patient handouts). more than 175 biomedical research tools have been licensed or selected from open-access content. the needs of biomedical researchers include molecular biology tools and software, biomedical literature databases, citation analysis, chemical and engineering databases, expertise-finding tools, laboratory tools and supplies, institutional-research resources, and upcoming seminars. the specific objectives of the search application are the following: n the user interface should be fast, simple, and intuitive, with embedded suggestions for improving search results (e.g., did you mean? didn’t find it? have you tried?). n search results from disparate local and external systems should be integrated into a single display based on popular search-engine models familiar to the target population. n the query-retrieval and results display should be separated and reusable to allow customization by role or domain and future expansion into other institutional tools. n resource results should be ranked by relevance and filtered by genre. n metasearch results should be hit counts and filtered by category for speed and breadth. results should be reusable for specific views by role. n finding a known article or journal should be streamlined and directly link to the item or “get item” option. n the most popular search options (pubmed, google, and lane journals) should be ubiquitous. n alternative pathways should be dynamic and interactive at the point of need to avoid backtracking and dead ends. n user behavior should be tracked by search term, resource used, and user location to help the library make informed decisions about licensing, metadata, and missing content. n off-the-shelf software should be used when available or appropriate with development focused on search integration. n the application should be built upon existing metadata-creation systems and trusted webdevelopment technologies. based on these objectives, we designed an application that is an extension of existing systems and technologies. resources are acquired and metadata are provided using the voyager integrated library system (ils). the sfx openurl link resolver provides full-text article access and expands the title search beyond biomedicine to all online journals at stanford. ezproxy provides seamless off-campus access. webtrends provides usage tracking. movable type is used to create faq and help information. a locally developed metasearch application provides a cross search with hit results from more than three hundred external and internal full-text sources. the technologies used to build laneconnex and integrate all of these systems include extensible stylesheet language laneconnex | ketchell et al. 33 transformations (xslt), java, javascript, the apache cocoon project, and oracle. n systems description architecture laneconnex is built on a principle of separation of concerns. the lane content owner can directly change the inclusion of search results, how they are displayed, and additional path-finding information. application programmers use java, javascript, xslt, and structured query language (sql) to create components that generate and modify the search results. the merger of content design and search results occurs “just in time” in the user’s browser. we use component-oriented programming design whereby services provided within the application are defined by simple contracts. in laneconnex, these components (called “transformers”) consume xml information and, after transforming it in some way, pass it on to some other component. a particular contract can be fulfilled in different ways for different purposes. this component architecture allows for easy extension of the underlying apache cocoon application. if laneconnex needs to transform some xml data that is not possible with built-in cocoon transformers, it is a simple matter to create a software component that does what is needed and fulfills the transformer contract. apache cocoon is the underlying architecture for laneconnex, as illustrated in figure 1. this java servlet is an xml–publishing engine that is built upon a component framework and uses a pipeline-processing model. a declarative language uses pattern matching to associate sets of processing components with particular request urls. content can come from a variety of sources. we use content from the local file system, network file system, http, and a relational database. the xslt language is used extensively in the pipelines and gives fine control of individual parts of the documents being processed. the end of processing is usually an xhtml document but can be any common mime type. we use cocoon to separate areas of concern so things like content, look and feel, and processing can all be managed as separate entities by different groups of people with little effect on another area. this separation of concerns is manifested by template documents that contain most of the html content common to all pages and are then combined with content documents within a processing pipeline. the declarative nature of the sitemap language and xslt facilitate rapid development with no need to redeploy the entire application to make changes in its behavior. the laneconnex search is composed of several components integrated into a query-and-results interface: oracle resource metadata, full-text metasearch application, movable type blogging software, “did you mean?” spell checker, ezproxy remote access, and webtrends tracking. n full-text metasearch integration of results from lane’s metasearch application illustrates cocoon’s many strengths. when a user searches laneconnex, cocoon sends his or her query to the metasearch application, which then dispatches the request to multiple external, full-text search engines and content stores. some examples of these external resources are uptodate, access medicine, micromedex, pubmed, and md consult. the metasearch application interacts with these external resources through jakarta commons http clients. responses from external resources are turned into w3c document object model (dom) objects, and xpath expressions are used to resolve hit counts from the dom objects. as result counts are returned, they are added to an xml–based result list and returned to cocoon. the power of cocoon becomes evident as the xml– based metasearch result list is combined with a separate display template. this template-based approach affords content curators the ability to directly add, group, and describe metasearch resources using the language and look that is most meaningful to their specific user communities. for example, there are currently eight metasearch templates curated by an informationist in partnership with a target community. curating these templates requires little to no assistance from programmers. in lane’s 2005 interface, a user’s request was sent to the metasearch application, and the application waited five seconds before responding to give external resources a chance to return a result. hit counts in the user interface included a link to refresh and retrieve more results from external resources that had not yet responded. usability studies showed this to be a significant user barrier, since the refresh link was rarely clicked. the initial five second delay also gave users the impression that the site was slow. the laneconnex application makes heavy use of javascript to solve this problem. after a user makes her initial request, javascript is used to poll the metasearch application (through cocoon) on the user’s behalf, popping in result counts as external resources respond. this adds a level of interactivity previously unavailable and makes the metasearch piece of laneconnex much more successful than its previous version. resource metadata laneconnex replaces the catalog as the primary discovery interface. metadata describing locally owned and 34 information technology and libraries | march 2009 licensed resources (journals, databases, books, videos, images, calculators, and software applications) are stored in the library’s current system of record, an instance of the voyager ils. laneconnex makes no attempt to replace voyager ’s strengths as an application for the selection, acquisition, description, and management of access to library resources. it does, however, replace voyager ’s discovery interface. to this end, metadata for about eight thousand digital resources is extracted from voyager ’s oracle database, converted into marcxml, processed with xslt, and stored in a simple relational database (six tables and twenty-nine attributes) to support fast retrieval speed and tight control over search syntax. this extraction process occurs nightly, with incremental updates every five minutes. the oracle text search engine provides functionality anticipated by our internet-minded users. key features are speed and relevance-ranked results. a highly refined results ranking insures that the logical title appears in the first few results. a user ’s query is parsed for wildcard, boolean, proximity, and phrase operators, and then translated into an sql query. results are then transformed into a display version. related services laneconnex compares a user’s query terms against a dictionary. each query is sent to a cocoon spell-checking component that returns suggestions where appropriate. this component currently uses the simple object figure 1. laneconnex architecture. laneconnex | ketchell et al. 35 access protocol (soap)–based spelling service from google. google was chosen over the national center for biotechnology information (ncbi) spelling service because of the breadth of terms entered by users; however, cocoon’s component-oriented architecture would make it trivial to change spell checkers in the future. each query is also compared against stanford’s openurl link resolver (findit@stanford). client-side javascript makes a cocoon-mediated query of findit@stanford. using xslt, findit@stanford responses are turned into javascript object notation (json) objects and popped into the interface as appropriate. although the vast majority of laneconnex searches result in zero findit@stanford results, the convenience of searching all of lane’s systems in a single, unified interface far outweighs the effort of implementation. a commercial analytics tool called webtrends is used to collect web statistics for making data-centric decisions about interface changes. webtrends uses client-side javascript to track specific user click events. libraries need to track both on-site clicks (e.g., the user clicked on “clinical portal” from the home page) and off-site clicks (e.g., the user clicked on “yamada’s gastroenterology” after doing a search for “ibs”). to facilitate off-site click capture, webtrends requires every external link to include a snippet of javascript. requiring content creators to input this code by hand would be error prone and tedious. laneconnex automatically supplies this code for every class of link (search or static). this specialized webtrends method provides lane with data to inform both interface design and licensing decisions. n results laneconnex version 1.0 was released to the stanford biomedical community in july 2006. the current application can be experienced at http://lane.stanford.edu. the figure 2. laneconnex resource search results. resource results are ranked by relevance. single word titles are given a higher weight in the ranking algorithm to insure they are displayed in the first five results. uniform titles are used to co-locate versions (e.g., the three instances of science from different producers). journals titles are linked to their respective impact factor page in the isi web of knowledge. digital formats that require special players or restrictions are indicated. the metadata searched for ejournals, databases, ebooks, biotools, video, and medcalcs are lane’s digital resources extracted from the integrated library system into a searchable oracle database. the first “all” tab is the combined results of these genres and the lane site help and information. figure 3. laneconnex related services search enhancements. laneconnex includes a spell checker to avoid a common failure in user searches. ajax services allow the inclusion of search results from other sources for common zero results failures. for example, the stanford link resolver database is simultaneously searched to insure online journals outside the scope of biomedicine are presented as a linked result for the user. production version has proven reliable over two years. incremental user focus groups have been employed to improve the interface as issues arose. a series of vignettes will be used to illustrate how the current version of 36 information technology and libraries | march 2009 the “sunetid login” is required. n user query: “new yokrer.” a faculty member is looking for an article in the new yorker for a class reading assignment. he makes a typing error, which invokes the “did you mean?” function (see figure 3). he clicks on the correct spelling. no results are found in the resource search, but a simultaneous search of the link-resolver database finds an instance of this title licensed for the campus and displays a clickable link for the user. n user query: “pathway analysis.” a post–doc is looking for information on how to share an ingenuity pathway. figure 4 illustrates the integration of the locally created lane faqs. faqs comprise a broad spectrum of help and how-to information as described by our focus groups. help text is created in the movable type blog software, and made searchable through the laneconnex application. the movable type interface lowers the barrier to html content creation by any staff member. more complex answers include embedded images and videos to enable the user to see exactly how to do a particular procedure. cocoon allows for the syndication of subsets of this faq content back into static html pages where it can be displayed as both category-specific lists or as the text for scroll-over help for a link. having a single store of help information insures the content is updated once for all instances. n user query: “uterine cancer kapp.” a resident is looking for a known article. laneconnex simultaneously searches pubmed to increase the likelihood of user success (see figure 5). clicking on the pubmed tab retrieves the results in the native interface; however, the user sees the pubmed@stanford version, which includes embedded links to the article based on our openurl link resolver. the ability to retrieve results from bibliographic databases that includes article resolution insures that our biomedical community is always using the correct url to insure maximum full-text article access. user testing in 2007 found that adding the three most frequently used sources (pubmed, google, and lane catalog) into our one-box laneconnex search was a significant time saver. it addresses laneconnex meets the design objectives from the user’s perspective. n user query: “science.” a graduate student is looking for the journal science. the laneconnex results are listed in relevance order (see figure 2). singleword titles are given a higher weight in the ranking algorithm to insure they are displayed in the first five results. results from local metadata are displayed by uniform title. for example, lane has three instances of the journal science, and each version is linked to the appropriate external store. brief notes provide critical information for particular resources. for example, restricted local patient education documents and video seminars note that figure 4. example of integration of local content stores. help information is managed in moveable type and integrated into laneconnex search results. laneconnex | ketchell et al. 37 the expectation on the part of our users that they could search for an article or a journal title in a single search box without first selecting a database. n user query: “serotonin pulmonary hypertension.” a medical student is looking for the correlation of two topics. clicking on the “clinical” tab, the student sees the results of the clinical metasearch in figure 6. metasearch results are deep searches of sources within licensed packages (e.g., textbooks in md consult or a specific database in micromedex), local content (e.g., stanford’s lab-test database), and openaccess content (e.g., ncbi databases). pubmed results are tailored strategies tiered by evidence. for example, the evidence-summaries strategy retrieves results from twelve clinical-evidence resources (e.g., buj, clinical evidence, and cochrane systematic reviews) that link to the full-text licensed by stanford. an example of the bioresearch metasearch is shown in figure 7. content selected for this audience includes literature databases, funding sources, patents, structures, clinical trials, protocols, and stanford expertise integrated with gene, protein, and phenotype tools. user testing revealed that many users did not click on the “clinical” tab. the clinical metasearch was originally developed for the clinical portal page and focused on clinicians in practice; however, the results needed to be exposed more directly as part of the laneconnex search. figure 8 illustrates the “have you tried?” feature that displays a few relevant clinical-content sources without requiring the user to select the “clinical” tab. this feature is managed by the smartsearch component of the laneconnex system. smartsearch sends the user’s query terms to pubmed, extracts a subset of articles associated with those terms, extracts the mesh headings for those articles, and computes the frequency of headings in the articles to determine the most likely mesh terms associated with the user’s query terms. these mesh terms are mapped to mesh terms associated with each metasearch resource. preliminary evaluation indicates that the clinical content is now being discovered by more users. figure 5. example of integration of popular search engines into laneconnex results. three of the most popular searches based on usage analysis are included at the top level. pubmed and google are mapped to lane’s link resolver to retrieve the full article. creating or editing metasearch templates is a curator driven task. programming is only required to add new sources to the metasearch engine. a curator may choose from more than three hundred sources to create a discipline-based layout using general templates. names, categories, and other description information are all at the curator ’s discretion. while developing new subspecialty templates, we discovered that clinicians were confused by the difference in layout of their specialty portal and their metasearch results (e.g., the cardiology portal used the generic clinical metasearch). to address this issue, we devised an approach that merges a portal and metasearch into a single entity as illustrated in figure 9. a combination of the component-oriented architecture of laneconnex and javascript makes the integration of metasearch results into a new template patterned after a portal easy to implement. this strategy will enable the creation of templates contextually appropriate to knowledge requests originating from electronic medical-record systems in the future. direct user feedback and usage statistics confirm that search is now the dominant mode of navigation. the amount of time each user spends on the website has dropped since the release of version 1.0. we speculate that the integrated search helps our users find relevant 38 information technology and libraries | march 2009 information more efficiently. focus groups with students are uniformly positive. graduate students like the ability to find digital articles using a single search box. medical students like the clinical metasearch as an easy way to look up new topics in texts and customized pubmed searches. bioengineering students like the ability to easily look up patient care–related topics. pediatrics residents and attendings have championed the development of their portal and metasearch focused on their patient population. medical educators have commented on their ability to focus on the best information sources. n discussion a review of websites in 2007 found that most biomedical libraries had separate search interfaces for their digital resources, library catalog, and external databases. biomedical libraries are implementing metasearch software to cross search proprietary databases. the university of california, davis is using the metalib software to federate searching multiple bibliographic databases.8 the university of south california and florida state university are using webfeat software to search clinical textbooks.9 the health sciences library system at the university of pittsburgh is using vivisimo to search clinical textbooks and bioresearch tools.10 academic libraries are introducing new “resource shopping” applications, such as the endeca project at north carolina state university, the summa project at the university of aarhus, and the vufind project at villanova university.11 these systems offer a single query box, faceted results, spell checking, recommendations based on user input, and asynchronous javascript and xml (ajax) for live status information. we believe our approach is a practical integration for our biomedical community that bridges finding a resource and finding a specific item through figure 6. integration of metasearch results into laneconnex. results from two general, role-based metasearches (bioresearch and clinical) are included in the laneconnex interface. the first image shows a clinician searching laneconnex for serotonin pulmonary hypertension. selecting the clinical tab presents the clinical content metasearch display (second image), and is placed deep inside the source by selecting a title (third image). laneconnex | ketchell et al. 39 a metasearch of multiple databases. the laneconnex application searches across digital resources and external data stores simultaneously and presents results in a unified display. the limitation to our approach is that the metasearch returns only hit counts rather than previews of the specific content. standardization of results from external systems, particularly receipt of xml results, remains a challenge. federated search engines do integrate at this level, but are usually slow or limit the number of results. true integration awaits health level seven (hl7) clinical decision support standards and national information standards organization (niso) metasearch initiative for query and retrieval of specific content.12 one of the primary objectives of laneconnex is speed and ease of use. ranking and categorization of results has been very successful in the eyes of the user community. the integration of metasearch results has been particularly successful with our pediatric specialty portal and search. however, general user understanding of how the clinical and biomedical tabs related to the genre tabs in laneconnex has been problematic. we reviewed web engines and found a similar challenge in presenting disparate format results (e.g., video or image search results) or lists of hits from different systems (e.g., ncbi’s entrez search results).13 we are continuing to develop our new specialty portal-and-search model and our smartsearch term-mapping component to further integrate results. n conclusion laneconnex is an effective and openended search infrastructure for integrating local resource metadata and full-text content used by clinicians and biomedical researchers. its effectiveness comes from the recognition that users prefer a single query box with relevance or categorically organized results that lead them to the most likely figure 7. example of a bioresearch metasearch. figure 8. the smartsearch component embeds a set of the metasearch results into the laneconnex interface as “have you tried?” clickable links. these links are the equivalent of selecting the title from a clinical metasearch result. the example search for atypical malignant rhabdoid tumor (a rare childhood cancer) invokes oncology and pediatric textbook results. these texts and pubmed provide quick access for a medical student or resident on the pediatric ward. figure 9. example of a clinical specialty portal with integrated metasearch. clinical portal pages are organized so metasearch hit counts can display next to content links if a user executes a search. this approach removes the dissonance clinicians felt existed between separate portal page and metasearch results in version 1.0. 40 information technology and libraries | march 2009 answer to a question or prospects in their exploration. the application is based on separation of concerns and is easily extensible. new resources are constantly emerging, and it is important that libraries take full advantage of existing and forthcoming content that is tailored to their user population regardless of the source. the next major step in the ongoing development of laneconnex is becoming an invisible backend application to bring content directly into the user’s workflow. n acknowledgements the authors would like to acknowledge the contributions of the entire laneconnex

cover 4 index to advertisers the lc/marc record as a national standard 159 the desire to promote exchange of bibliographic data has given rise to a rather cacophonous debate concerning marc as a "standard," and the definition of a marc compatible record. much of the confusion has arisen out of a failure to carefully separate the intellectual content of a bibliographic record, the specific analysis to which it is subjected in an lc/marc format, and its physical representation on magnetic tape. in addition, there has been a tendency to obscure the different requirements of users and creators of machine-readable bibliographic data. in general, the standards making process attempts to find a consensus among both groups based on existing practice. the process of standardization is rarely one which relies on enlightened legislation. rather, a more pragmatic approach is taken based on an evaluation of the costs to manufacturers weighed against costs to consumers. even this modest approach is not invested with lasting wisdom. ansi standards, for example, are subject to quinquennial review. standards, as already pointed out, have as their basis common acceptance of conventions. thus, it might prove useful to examine the conventions employed in an lc/marc record. the most important of these is the anglo-american cataloging rules as interpreted by lc. the use of these rules for descriptive cataloging and choice of entry is universal enough that they may safely be considered a standard. similar comments may be made concerning the subject headings used in the dictionary catalog of the library of congress. the physical format within which machine-readable bibliographic data may be transmitted is accepted as a codified national and international standard (ansi z39.2-1971 and iso 2709-1973 (e) ) . this standard, which is only seven pages in length, should be carefully read by anyone seriously concerned with the problems of bibliographic data interchange. ansi z39.2 is quite different from the published lc/ marc formats. it defines little more than the structure of a variable length record. simply stated, ansi z39.2 specifies only that a record shall contain a leader specifying its physical attributes, a directory for identifying elements within the record by numeric tag (the values of the tags are not defined), and optionally, additional designators which may be used to provide further information regarding fields and subfields. this structure is completely general. within this same structure one could transmit book 160 1 oumal of library automation vol. 7 i 3 september 197 4 orders, a bibliographic record, an abstract, or an authority record by adopting specific conventions regarding the interpretation of numeric tags. thus, we come to the crux of the problem, the meanings of the content designators. content designators (numeric tags, subfields, delimiters, etc.) are not synonymous with elements of bibliographic description; rather, they represent the level of explicitness we wish to achieve in encoding a record. it might safely be said that in the most common use of a marc record-card production-scarcely more than the paragraph distinctions on an lc card are really necessary. if we accept such an argument, then we can simply define compatibility with lc/marc by defining compatibility in terms of a particular class of applications, e.g., card, book, or crt catalog creation. a record may be said to be compatible with lcjmarc if a system which accepts a record as created by lc produces from the compatible 1·ecord products not discernibly different from those created from an lc/marc record. thus, what is called for is a family of standards all downwardly compatible with lc/marc, employing ansi z39.2 as a structural base. this represents the only rational approach. the alternative is to accept lc/ marc conventions as worthy of veneration as artistic expression. s. michael malinconico adding value to the university of oklahoma libraries history of science collection through digital enhancement maura valentino information technology and libraries | march 2014 25 “in getting my books, i have been always solicitous of an ample margin; this not so much through any love of the thing itself, however agreeable, as for the facility it affords me of penciling suggested thoughts, agreements and differences of opinion, or brief critical comments in general.” —edgar allan poe abstract much of the focus of digital collections has been and continues to be on rare and unique materials, including monographs. a monograph may be made even rarer and more valuable by virtue of hand written marginalia. using technology to enhance scans of unique books and make previously unreadable marginalia readable increases the value of a digital object to researchers. this article describes a case study of enhancing the marginalia in a rare book by copernicus. background the university of oklahoma libraries history of science collections holds many rare books and other objects pertaining to the history of science. one of the rarest holdings is a copy of nicolai copernici torinensis de revolvtionibvs orbium coelestium (on the revolutions of the heavenly spheres), libri vi, a book famous for copernicus’ revolutionary astronomical theory that rejected the ptolemaic earth-centered universe and promoted a heliocentric, sun-centered model. the history of science collections’ copy of this manuscript contains notes added to the margins. similar notes were made in eight different existing copies, and the astrophysicist owen gingerich determined that these notes were created by a group of astronomers in paris known as the offusius group.1 the notes are of significant historical importance as they offer information on the initial reception of copernicus’ theories by the catholic community. having been created almost five hundred years ago in 1543, the handwriting is faded and the ink has absorbed into the paper. maura valentino (maura.valentino@oregonstate.edu) is metadata librarian, oregon state university, corvalis, oregon. previously she was digital initiatives coordinator at the university of oklahoma. mailto:maura.valentino@oregonstate.edu adding value to collections through digital enhancement | valentino 26 written in cursive script, the letters have merged as the ink has dispersed, adding to the difficulties inherent in reading these valuable annotations. the book had previously been digitized, and while some of the margin notes were readable, many of the notes were barely visible. therefore much of the value of the book was being lost in digital form. to rectify this situation the decision was made to enhance the marginalia. it was further decided that once the margin notes were enhanced, two digital representations of each page that contained notes would be included in the digital collection. one copy would present the main text in the most legible fashion (figure 1) and the second copy would highlight the marginalia and ensure that these margin notes were as legible as possible even if in doing so the readability of the main text was diminished (figure 2). figure 1. text readable. figure 2. marginalia enhanced. while creating a written transcript of the marginalia was considered and would have added some value to the digital object, this solution was rejected in favor of digital enhancement for the following reasons. many of the notes contained corrections with lines drawn to the area of text that was being changed, or bracket numbers (figure 3). in addition, some of the notes are corrections of numbers or tables, so a transcript of the text would do little to demonstrate the writer’s intentions in creating the margin note (figure 4). figure 3 .bracketed corrections. figure 4. numerical corrections. information technology and libraries | march 2014 27 also, sometimes there was bleed through from the reverse page, further disrupting the clarity of the marginalia (figures 5 and 6). therefore it was determined that making the notes more readable through digital enhancement would provide the collection’s users with the most useful resource. figure 5. highlighted—bleed through reduced figure 6. bleed through behind. marginalia. the book can be viewed in its entirety here: http://digital.libraries.ou.edu/cdm/landingpage/collection/copernicus literature review “modification of photographs to enhance or change their meaning is nothing new. however, the introduction of techniques for digitizing photographic images and the subsequent development of powerful image editing software has both broadened the possibilities for altering photographs and brought the means of doing so with the reach of anyone with imagination and patience.”2 —richard s. croft the primary goal of this project was to give researchers in the history of science the ability to clearly decipher the marginalia created by the astronomers of the offusius group as they annotated the book using the margins as an editing space. the literature agrees that marginalia is an important piece of history worth preserving. hauptman states, “the thought that produces the necessity for a citation or remark leads directly into the marginal notation.”3 he also adds, “their close proximity to the text allows for immediate visual connection.”4 howard asserts, “for writers and scholars, the margins and endpapers became workshops in which to hammer out their own ideas, and offered spaces in which to file and store information.”5 she also adds that marginalia can “serve as a form of opposition.”6 this is true in this case as some of the marginalia http://digital.libraries.ou.edu/cdm/landingpage/collection/copernicus adding value to collections through digital enhancement | valentino 28 contradicts copernicus. nikolova-houston argues for the historical aspect: “each of the marginalia and colophons is a unique production by its author, and exists in only one copy.”7 she goes on to add, “manuscript marginalia and colophons possess historical value as primary historical sources. they are treated as historical evidence along with other written and oral traditions.”8 such ideas provide a strong justification for the implementation of marginalia enhancement in digital collections. as mentioned above, it was determined that a transcription would not have had the same effect as digital enhancement of the margin notes. this approach is also supported by the literature. for example, ferrari argues for the digital publication of the marginalia that fernando pessoa, the portuguese writer, made while reading. one of the cornerstones of his argument is that digital representation of marginalia allows the reader not only to see the words but also the underlining and other symbols that are not easily put into a transcript. in this way, the user of the digital collection obtains a more complete view of the author of the marginalia’s intent.9 another goal of this project was the general promotion of the university of oklahoma’s history of science collections. johnson, in his new york times article, notes that marginalia lend books an historical context while enabling users to infer other meanings from their texts.10 he also quotes david spadafora, president of the newberry library in chicago, who proclaims that “the digital revolution is a good thing for the physical object.” as more people access historical artifacts in electronic form, he notes, “the more they’re going to want to encounter the real object.”11 in this way, enhancement of the marginalia in digital collections can lead to further exposure for the collection and to greater use of the physical objects themselves. using digital enhancement is not a new idea. morgan asserts, “the innovation of the world wide web is its exciting capacity for space that, while not limitless, is weightless and far less limited that that of the printed book.”12 le, anderson and agarwala also add, “local manipulation of color and tone is one of the most common operations in the digital imaging workflow.”13 the literature shows that other projects have used enhancement of the digital object to increase the usefulness of the original artifact. one of the projects pursued during the library of congress’s american memory initiative involved the digitization of the work of photographer solomon butcher. in this case, technicians were able to enhance an area of one photograph that was blurry in normal photographic processes and allow the viewer to see inside a building.14 the archivo general de indias also used digital enhancement to remove stains and bleed-through from ancient manuscripts and render previously unreadable manuscripts readable.15 in an article advocating for a digital version of william blakes’s poem the four zoas, morgan notes that some features of the manuscript can only be seen in the digital version rather than a transcription: “sections of the manuscript show intense revision, with passages rubbed out, moved earlier or later in the manuscript, and often, added in the margins.”16 information technology and libraries | march 2014 29 digital processing is not limited to the use of photo editing software. although giralt asserts that it is a common method, “the ample potential for image control and manipulation provided by digital technology has stirred a great interest in postproduction, and digital editing.”17 other projects have used various technologies to enhanced images to give added meaning to a digital image. once again, in her article advocating for the digitizing of william blake’s the four zoas, morgan asserts that various enhancement technologies would help readers obtain the greatest benefit from the manuscript. for example, providing “the added benefit of infra-red photography,” would allow “readers to see many of the erased illustrations.”18 she even hopes coding will enhance the usefulness of a digital object: “our impulse to use xml in order to richly encode a text works against passivity. with coding we clarify a work down to its smallest units, and illuminate specific aspects of its structure, aspects that are often less obvious when the work is presented in the form of a printed book.”19 method locating the marginalia each page of the book had been previously scanned and was stored in tagged image file format (tiff). each digital page (tiff image) was carefully examined for marginalia. this was achieved by examining the image in adobe photoshop using the zoom tool to enlarge the image as necessary. as many notes were barely visible, the entirety of each page had to be examined in detail to ensure that margin notes were not overlooked. enlargement of the image in photoshop greatly facilitated this process. enhancing the marginalia once all the pages with marginalia were identified, each page was loaded into adobe photoshop for digital processing and enhancement. the following procedure was used (note: the specific directions that follow reference adobe photoshop cs4 for windows but can be generally applied to most software programs intended for photo editing): 1. using the zoom tool, the image was enlarged to facilitate examination and interaction with the marginalia. 2. individual margin notes were selected using the rectangular marquee tool. the area selected included any lines that were drawn from the notes to the original text so it would be clear to what text the margin note referred. 3. as the handwritten margin notes were orange in tone, a blue filter was applied (as blue is the contrasting color to orange) by selecting adjustments from the image menu and then choosing black and white to display the black and white dialog box. in the black and white dialog box, blue filter was selected from the preset drop-down menu. this small adjustment greatly enhanced the readability of the margin notes. 4. with the area still selected, adjustments was again selected from the image menu. from that adjustments submenu, brightness and contrast was selected. adjustments were made to both these values using the sliders presented by the resulting dialog box to adding value to collections through digital enhancement | valentino 30 further enhance the margin notes legibility. for this particular project, the values selected were generally negative twenty for contrast and positive twenty for brightness. file naming conventions each enhanced image was saved with the same filename as the digital image of the original manuscript page, but with an a (for annotated) added to the end of the filename. this naming scheme enabled a distinction between pages with and without enhanced marginalia. this series of steps was repeated for each page (see table 1). page name explanation book spine pictures of the covers book cover inside cover blank page with ruler to measure page folio 001 page 1 as originally scanned folio 001 verso page 1, reverse side, as originally scanned folio 001 verso a page 1, reverse side, with highlighted marginalia folio 002 page 2 as originally scanned folio 002a page 2 with highlighted marginalia folio 002 v page 2, reverse side folio 002 v a page 2, reverse side, with highlighted marginalia table 1. filenames. importing into the digital management system contentdm was the digital management system selected for this project. all original manuscript page images and enhanced marginalia page images were imported into contentdm following their creation. the next step was to bring all the pages into contentdm as one compound object. a microsoft excel spreadsheet was created with a line for each page, annotated or not. only three fields were used: title, rights, and filename. a description of the book was placed on its history of science digital collections webpage with a link to the compound object in contentdm, so further metadata was not necessary and can always be added later. the first row only contained the title of the book (no filename). there were tiffs available of the cover, the bookend, the inside cover, and the book with a ruler. these were the next rows. then we began with the pages and titled them as the pages were numbered. there were ten pages numbered with roman numerals and then the pages began with alphanumeric page numbers. each page that had handwritten notes had the original page (page 2, for example) and the page with the information technology and libraries | march 2014 31 notes highlighted (page 2 annotated). this would allow the viewer to view the pages in their original form or with the notes highlighted or both, depending on each user’s research interests. once the excel file was complete with each page and its filename entered in a row, the file was saved as a tab-delimited file. import into contentdm required that all the tiff files be in one folder. once the files were moved, the contentdm compound object wizard was used to import. this book was imported as a compound object with no hierarchy. as this book was published in 1593, it has no chapters. to specify page names, the choice to label pages using tab-delimited object for printing was used. the filenames did not contain page numbers, and the choice to label pages in a sequence was not an option, as two copies of each annotated page existed. each object imported into contentdm has a thumbnail image associated with it. contentdm will create this image, but the cover of this book is not attractive, so a jpeg file was created using an image from the book that is often associated with copernicus (see figure 3). conclusions this project resulted in a digital representation of the physical book that is much more useful to researchers than the original, unenhanced digital object. this history of science collection holds not only the first edition of books important to the history of science, but the subsequent editions so that researchers can see how the ideas of science have changed over time. this new digital edition of de revolutionibus allows researchers to see how another scientist made corrections in copernicus’ book as one step in the change in theory over time and insight into the reaction of the catholic church. the format that contentdm creates for the object and a clear naming scheme allow the user to view the pages with or without the marginalia, thus making this a useful object for many types of users (see figure 4). however, using photoshop to highlight areas of a page allowed the digital initiatives department to understand the power of this tool. in understanding the utility and power of photoshop, the digital initiatives department has determined it to be a useful tool in other projects. a project to eliminate some images of people’s fingers that inadvertently were photographed along

mandates, and other mandates such as the one instituted at stanford’s school of education, have come to pass, and the registry of open access repository material archiving policies (roarmap) lists more than 120 mandates around the world that now exist.3 while it is too early to tell whether these developments will be successful in getting faculty to deposit their work in digital repositories, they at least establish a precedent that other institutions may follow. how many institutions follow and how effective the mandates will be once enacted remains to be seen. will all colleges and universities, or even a majority, adopt mandates that require faculty to deposit their work in repositories? what of those that do not? even if most institutions are successful in instituting mandates, will they be sufficient to obtain faculty cooperation? for those institutions that do not adopt mandates, how are they going to persuade faculty to participate in self-archiving, or even in some variation—such as having surrogates (librarians, staff, or graduate assistants) archive the work of faculty? are mandates the only way to ensure faculty cooperation and compliance, or are mandates even necessarily the best way? to begin to adequately address the problem of user resistance to digital repositories, it might help to first gain some insight into the psychology of resistance. the existing literature on user behavior with regard to digital repositories devotes scant attention to the psychology of resistance. in an article entitled “institutional repositories: partnering with faculty to enhance scholarly communication,” johnson discusses the inertia of the traditional publishing paradigm. he notes that this inertia is most evident in academic faculty. this would suggest that the problem of eliciting user cooperation is primarily motivational and that the problem is more one of indifference than active resistance.4 heterick, in his article “faculty attitudes toward electronic resources,” suggests that one reason faculty may be resistant to digital repositories is because they do not fully trust them. in response to a survey he conducted, 48 percent of faculty felt that libraries should maintain paper archives.5 the implication is that digital repositories and archives may never completely replace hard copies in the minds of scholars. in “understanding faculty to improve content recruitment for institutional repositories,” foster and gibbons point out that faculty complain of having too much work already. they resent any additional work that contributing to a digital repository might entail. thus the authors echo johnson in suggesting that faculty resistance the potential value of digital repositories is dependent on the cooperation of scholars to deposit their work. although many researchers have been resistant to submitting their work, the literature on digital repositories contains very little research on the psychology of resistance. this article looks at the psychological literature on resistance and explores what its implications might be for reducing the resistance of scholars to submitting their work to digital repositories. psychologists have devised many potentially useful strategies for reducing resistance that might be used to address the problem; this article examines these strategies and how they might be applied. o bserving the development and growth of digital repositories in recent years has been a bit like riding an emotional roller coaster. even the definition of what constitutes a repository may not be the subject of complete agreement, but for the purposes of this study, a repository is defined as an online database of digital or digitized scholarly works constructed for the purpose of preserving and disseminating scholarly research. the initial enthusiasm expressed by librarians and advocates of open access toward the potential of repositories to make significant amounts of scholarly research available to anyone with internet access gradually gave way to a more somber appraisal of the prospects of getting faculty and researchers to deposit their work. in august 2007, bailey posted an entry to his digital koans blog titled “institutional repositories: doa?” in which he noted that building digital repository collections would be a long, arduous, and costly process.1 the success of repositories, in his view, will be a function not so much of technical considerations as of attitudinal ones. faculty remain unconvinced that repositories are important, and there is a critical need for outreach programs that point to repositories as an important step in solving the crisis in scholarly communication. salo elaborated on bailey’s post with “yes, irs are broken. let’s talk about it,” on her own blog, caveat lector. salo points out that institutional repositories have not fulfilled their early promise of attracting a large number of faculty who are willing to submit their work. she criticizes repositories for monopolizing the time of library faculty and staff, and she states her belief that repositories will not work without deposit mandates, but that mandates are impractical.2 subsequent events in the world of scholarly communication might suggest that mandates may be less impractical than salo originally thought. since her post, the national institutes of health mandate, the harvard brian quinn (brian.quinn@ttu.edu) is social sciences librarian, texas tech university libraries, lubbock. brian quinn reducing psychological resistance to digital repositories 68 information technology and libraries | june 2010 whether or not this was actually the case.11 this study also suggests that a combination of both cognitive and affective processes feed faculty resistance to digital repositories. it can be seen from the preceding review of the literature that several factors have been identified as being possible sources of user resistance to digital repositories. yet the authors offer little in the way of strategies for addressing this resistance other than to suggest workaround solutions such as having nonscholars (e.g., librarians, graduate students, or clerical staff) serve as proxy for faculty and deposit their work for them, or to suggest that institutions mandate that faculty deposit their work. similarly, although numerous arguments have been made in favor of digital repositories and open access, they do not directly address the resistance issue.12 in contrast, psychologists have studied user resistance extensively and accumulated a body of research that may suggest ways to reduce resistance rather than try to circumvent it. it may be helpful to examine some of these studies to see what insights they might offer to help address the problem of user resistance. it should be pointed out that resistance as a topic has been addressed in the business and organizational literature, but has generally been approached from the standpoint of management and organizational change.13 this study has chosen to focus primarily on the psychology of resistance because many repositories are situated in a university setting. unlike employees of a corporation, faculty members typically have a greater degree of autonomy and latitude in deciding whether to accommodate new work processes and procedures into their existing routines, and the locus of change will therefore be more at an individual level. ■■ the psychology of user resistance psychologists define resistance as a preexisting state or attitude in which the user is motivated to counter any attempts at persuasion. this motivation may occur on a cognitive, affective, or behavioral level. psychologists thus distinguish between a state of not being persuaded and one in which there is actual motivation to not comply. the source of the motivation is usually an affective state, such as anxiety or ambivalence, which itself may result from cognitive problems, such as misunderstanding, ignorance, or confusion.14 it is interesting to note that psychologists have long viewed inertia as one form of resistance, suggesting paradoxically that a person can be motivated to inaction.15 resistance may also manifest itself in more subtle forms that shade into indifference, suspicion of new work processes or technologies, and contentment with the status quo. may be attributed at least in part to motivation.6 in another article published a few months later, foster and gibbons suggest that the main reason faculty have been slow to deposit their work in digital repositories is a cognitive one: faculty have not understood how they would benefit by doing so. the authors also mention that users may feel anxiety when executing the sequence of technical steps needed to deposit their work, and that they may also worry about possible copyright infringement.7 the psychology of resistance may thus manifest itself in both cognitive and affective ways. harley and her colleagues talk about faculty not perceiving any reward for depositing their work in their article “the influence of academic values on scholarly publication and communication practices.” this perception results in reduced drive to participate. anxiety is another factor contributing to resistance: faculty fear that their work may be vulnerable to plagiarism in an openaccess environment.8 in “towards user responsive institutional repositories: a case study,” devakos suggests that one source of user resistance is cognitive in origin. scholars do not submit their work frequently enough to be able to navigate the interface from memory, so they must reinitiate the learning process each time they submit their work. the same is true for entering metadata for their work.9 their sense of control may also be threatened by any limitations that may be imposed on substituting later iterations of their work for earlier versions. davis and connolly point to several sources of confusion, uncertainty, and anxiety among faculty in their article “institutional repositories: evaluating the reasons for non-use of cornell university’s installation of dspace.” cognitive problems arise from having to learn new technology to deposit work and not knowing copyright details well enough to know whether publishers would permit the deposit of research prior to publication. faculty wonder whether this might jeopardize their chances of acceptance by important journals whose editors might view deposit as a form of prior publication that would disqualify them from consideration. there is also fear that the complex structure of a large repository may actually make a scholar’s work more difficult to find; faculty may not understand that repositories are not isolated institutional entities but are usually searchable by major search engines like google.10 kim also identifies anxiety about plagiarism and confusion about copyright as being sources of faculty resistance in the article “motivating and impeding factors affecting faculty contribution to institutional repositories.” kim found that plagiarism anxiety made some faculty only willing to deposit already-published work and that prepublication material was considered too risky. faculty with no self-archiving experience also felt that many publishers do not allow self-archiving, reducing psychological resistance to digital repositories | quinn 69 more open to information that challenges their beliefs and attitudes and are more open to suggestion.18 thus before beginning a discussion of why users should deposit their research in repositories, it might help to first affirm the users’ self-concept. this could be done, for example, by reminding them of how unbiased they are in their work or how important it is in their work to be open to new ideas and new approaches, or how successful they have been in their work as scholars. the affirmation should be subtle and not directly related to the repository situation, but it should remind them that they are openminded individuals who are not bound by tradition and that part of their success is attributable to their flexibility and adaptability. once the users have been affirmed, librarians can then lead into a discussion of the importance of submitting scholarly research to repositories. self-generated affirmations may be even more effective. for example, another way to affirm the self would be to ask users to recall instances in which they successfully took a new approach or otherwise broke new ground or were innovative in some way. this could serve as a segue into a discussion of the repository as one more opportunity to be innovative. once the self-concept has been boosted, the threatening quality of the message will be perceived as less disturbing and will be more likely to receive consideration. a related strategy that psychologists employ to reduce resistance involves casting the user in the role of “expert.” this is especially easy to do with scholars because they are experts in their fields. casting the user in the role of expert can deactivate resistance by putting that person in the persuasive role, which creates a form of role reversal.19 rather than the librarian being seen as the persuader, the scholar is placed in that role. by saying to the scholar, “you are the expert in the area of communicating your research to an audience, so you would know better why the digital repository is an alternative that deserves consideration once you understand how it works and how it may benefit you,” you are empowering the user. casting the user as an expert imparts a sense of control to the user. it helps to disable resistance by placing the user in a position of being predisposed to agree to the role he or she is being cast in, which also makes the user more prone to agree with the idea of using a digital repository. priming and imaging one important discovery that psychologists have made that has some bearing on user resistance is that even subtle manipulations can have a significant effect on one’s judgments and actions. in an interesting experiment, psychologists told a group of students that they were to read an online newspaper, ostensibly to evaluate its design and assess how easy it was to read. half of them read an editorial discussing a public opinion survey of youth ■■ negative and positive strategies for reducing resistance just as the definition of resistance can be paradoxical, so too may be some of the strategies that psychologists use to address it. perhaps the most basic example is to counter resistance by acknowledging it. when scholars are presented with a message that overtly states that digital repositories are beneficial and desirable, it may simultaneously generate a covert reaction in the form of resistance. rather than simply anticipating this and attempting to ignore it, digital repository advocates might be more persuasive if they acknowledge to scholars that there will likely be resistance, mention some possible reasons (e.g., plagiarism or copyright concerns), and immediately introduce some counterrationales to address those reasons.16 psychologists have found that being up front and forthcoming can reduce resistance, particularly with regard to the downside of digital repositories. they have learned that it can be advantageous to preemptively reveal negative information about something so that it can be downplayed or discounted. thus talking about the weaknesses or shortcomings of digital repositories as early as possible in an interaction may have the effect of making these problems seem less important and weakening user resistance. not only does revealing negative information impart a sense of honesty and credibility to the user, but psychologists have found that people feel closer to people who reveal personal information.17 a librarian could thus describe some of his or her own frustrations in using repositories as an effective way of establishing rapport with resistant users. the unexpected approach of bringing up the less desirable aspects of repositories—whether this refers to the technological steps that must be learned to submit one’s work or the fact that depositing one’s work in a repository is not a guarantee that it will be highly cited—can be disarming to the resistant user. this is particularly true of more resistant users who may have been expecting a strong hard-sell approach on the part of librarians. when suddenly faced with a more candid appeal the user may be thrown off balance psychologically, leaving him or her more vulnerable to information that is the opposite of what was anticipated and to possibly viewing that information in a more positive light. if one way to disarm a user is to begin by discussing the negatives, a seemingly opposite approach that psychologists take is to reinforce the user’s sense of self. psychologists believe that one source of resistance stems from when a user’s self-concept—which the user tries to protect from any source of undesired change—has been threatened in one way or another. a stable self-concept is necessary for the user to maintain a sense of order and predictability. reinforcing the self-concept of the user should therefore make the user less likely to resist depositing work in a digital repository. self-affirmed users are 70 information technology and libraries | june 2010 or even possibly collaborating on research. their imaginations could be further stimulated by asking them to think of what it would be like to have their work still actively preserved and available to their successors a century from now. using the imagining strategy could potentially be significantly more effective in attenuating resistance than presenting arguments based on dry facts. identification and liking conscious processes like imagining are not the only psychological means of reducing the resistance of users to digital repositories. unconscious processes can also be helpful. one example of such a process is what psychologists refer to as the “liking heuristic.” this refers to the tendency of users to employ a rule-of-thumb method to decide whether to comply with requests from persons. this tendency results from users constantly being inundated with requests. consequently, they need to simplify and streamline the decision-making process that they use to decide whether to cooperate with a request. the liking heuristic holds that users are more likely to help someone they might otherwise not help if they unconsciously identify with the person. at an unconscious level, the user may think that a person acts like them and dresses like them, and therefore the user identifies with that person and likes them enough to comply with their request. in one experiment that psychologists conducted to see if people are more likely to comply with requests from people that they identify with, female undergraduates were informed that they would be participating in a study of first impressions. the subjects were instructed that they and a person in another room would each learn a little about one another without meeting each other. each subject was then given a list of fifty adjectives and was asked to select the twenty that were most characteristic of themselves. the experimenter then told the participants that they would get to see each other’s lists. the experimenter took the subject’s list and then returned a short time later with what supposedly was the other participant’s list, but was actually a list that the experimenter had filled out to indicate that either the subject had much in common with the other participant’s personality (seventeen of twenty matches), some shared attributes (ten of twenty matches), or relatively few characteristics in common (three of twenty matches). the subject was then asked to examine the list and fill out a survey that probed their initial impressions of the other participant, including how much they liked them. at the end of the experiment, the two subjects were brought together and given credit for participating. the experimenter soon left the room and the confederate participant asked the other participant if she would read and critically evaluate an eight-page paper for an english class. the results of the experiment indicated that the more the participant thought she shared in consumer patterns that highlighted functional needs, and the other half read a similar editorial focusing on hedonistic needs. the students next viewed an ad for a new brand of shampoo that featured either a strong or a weak argument for the product. the results of the experiment indicated that students who read the functional editorial and were then subsequently exposed to the strong argument for the shampoo (a functional product) had a much more favorable impression of the brand than students who had received the mismatched prime.20 while it may seem that the editorial and the shampoo were unrelated, psychologists found that the subjects engaged in a process of elaborating the editorial, which then predisposed them to favor the shampoo. the presence of elaboration, which is a precursor to the development of attitudes, suggests that librarians could reduce users’ resistance to digital repositories by first involving them in some form of priming activity immediately prior to any attempt to persuade them. for example, asking faculty to read a brief case study of a scholar who has benefited from involvement in open-access activity might serve as an effective prime. another example might be to listen briefly to a speaker summarizing the individual, disciplinary, and societal benefits of sharing one’s research with colleagues. interventions like these should help mitigate any predisposition toward resistance on the part of users. imagining is a strategy related to priming that psychologists have found to be effective in reducing resistance. taking their cue from insurance salesmen—who are trained to get clients to actively imagine what it would be like to lose their home or be in an accident—a group of psychologists conducted an experiment in which they divided a sample of homeowners who were considering the purchase of cable tv into two groups. one group was presented with the benefits of cable in a straightforward, informative way that described various features. the other group was asked to imagine themselves enjoying the benefits and all the possible channels and shows that they might experience and how entertaining it might be. the psychologists then administered a questionnaire. the results indicated that those participants who were asked to imagine the benefits of cable were much more likely to want cable tv and to subscribe to it than were those who were only given information about cable tv.21 in other words, imagining resulted in more positive attitudes and beliefs. this study suggests that librarians attempting to reduce resistance among users of digital repositories may need to do more than merely inform or describe to them the advantages of depositing their work. they may need to ask users to imagine in vivid detail what it would be like to receive periodic reports indicating that their work had been downloaded dozens or even hundreds of times. librarians could ask them to imagine receiving e-mail or calls from colleagues indicating that they had accessed their work in the repository and were interested in learning more about it, reducing psychological resistance to digital repositories | quinn 71 students typically overestimate the amount of drinking that their peers engage in at parties. these inaccurate normative beliefs act as a negative influence, causing them to imbibe more because they believe that is what their peers are doing. by informing students that almost threequarters of their peers have less than three drinks at social gatherings, psychologists have had some success in reducing excessive drinking behavior by students.23 the power of normative messages is illustrated by a recent experiment conducted by a group of psychologists who created a series of five cards to encourage hotel guests to reuse their towels during their stay. the psychologists hypothesized that by appealing to social norms, they could increase compliance rates. to test their hypothesis, the researchers used a different conceptual appeal for each of the five cards. one card appealed to environmental concerns (“help save the environment”), another to environmental cooperation (“partner with us to save the environment”), a third card appealed to the advantage to the hotel (“help the hotel save energy”), a fourth card targeted future generations (“help save resources for future generations”), and a final card appealed to guests by making reference to a descriptive norm of the situation (“join your fellow citizens in helping to save the environment”). the results of the study indicated that the card that mentioned the benefit to the hotel was least effective in getting guests to reuse their towels, and the card that was most effective was the one that mentioned that descriptive norm.24 this research suggests that if users who are resistant to submitting their work to digital repositories were informed that a larger percentage of their peers were depositing work than they realized, resistance may be reduced. this might prove to be particularly true if they learned that prominent or influential scholars were engaged in populating repositories with their work. this would create a social-norms effect that would help legitimize repositories to other faculty and help them to perceive the submission process as normal and desirable. the idea that accomplished researchers are submitting materials and reaping the benefits might prove very attractive to less experienced and less well-regarded faculty. psychologists have a considerable body of evidence in the area of social modeling that suggests that people will imitate the behavior of others in social situations because that behavior provides an implicit guideline of what to do in a similar situation. a related finding is that the more influential people are, the more likely it is for others to emulate their actions. this is even more probable for highstatus individuals who are skilled and attractive and who are capable of communicating what needs to be done to potential followers.25 social modeling addresses both the cognitive dimension of how resistant users should behave and also the affective dimension by offering models that serve as a source of motivation to resistant users to change common with the confederate, the more she liked her. the more she liked the confederate and experienced a perception of consensus, the more likely she was to comply with her request to critique the paper.22 thus, when trying to overcome the resistance of users to depositing their work in a digital repository, it might make sense to consider who it is that is making the request. universities sometimes host scholarly communication symposia that are not only aimed at getting faculty interested in open-access issues, but to urge them to submit their work to the institution’s repositories. frequently, speakers at these symposia consist of academic administrators, members of scholarly communication or open-access advocacy organizations, or individuals in the library field. the research conducted by psychologists, however, suggests that appeals to scholars and researchers would be more effective if they were made by other scholars and those who are actively engaged in research. faculty are much more likely to identify with and cooperate with requests from their own tribe, as it were, and efforts need to be concentrated on getting faculty who are involved in and understand the value of repositories to articulate this to their colleagues. researchers who can personally testify to the benefits of depositing their work are most likely to be effective at convincing other researchers of the value of doing likewise and will be more effective at reducing resistance. librarians need to recognize who their potentially most effective spokespersons and advocates are, which the psychological research seems to suggest is faculty talking to other faculty. perceived consensus and social modeling the processes of faculty identification with peers and perceived consensus mentioned above can be further enhanced by informing researchers that other scholars are submitting their work, rather than merely telling researchers why they should submit their work. information about the practices of others may help change beliefs because of the need to identify with other in-group members. this is particularly true of faculty, who are prone to making continuous comparisons with their peers at other institutions and who are highly competitive by nature. once they are informed of the career advantages of depositing their work (in terms of professional visibility, collaboration opportunities, etc.), and they are informed that other researchers have these advantages, this then becomes an impetus for them to submit their work to keep up with their peers and stay competitive. a perception of consensus is thus fostered—a feeling that if one’s peers are already depositing their work, this is a practice that one can more easily agree to. psychologists have leveraged the power of identification by using social-norms research to inform people about the reality of what constitutes normative behavior as opposed to people’s perceptions of it. for example, college 72 information technology and libraries | june 2010 highly resistant users that may be unwilling to submit their work to a repository. rather than trying to prepare a strong argument based on reason and logic, psychologists believe that using a narrative approach may be more effective. this means conveying the facts about open access and digital repositories in the form of a story. stories are less rhetorical and tend not to be viewed by listeners as attempts at persuasion. the intent of the communicator and the counterresistant message are not as overt, and the intent of the message might not be obvious until it has already had a chance to influence the listener. a well-crafted narrative may be able to get under the radar of the listener before the listener has a chance to react defensively and revert to a mode of resistance. in a narrative, beliefs are rarely stated overtly but are implied, and implied beliefs are more difficult to refute than overtly stated beliefs. listening to a story and wondering how it will turn out tends to use up much of the cognitive attentional capacity that might otherwise be devoted to counterarguing, which is another reason why using a narrative approach may be particularly effective with users who are strongly resistant. the longer and more subtle nature of narratives may also make them less a target of resistance than more direct arguments.28 using a narrative approach, the case for submitting work to a repository might be presented not as a collection of dry facts or statistics, but rather as a story. the protagonists are the researchers, and their struggle is to obtain recognition for their work and to advance scholarship by providing maximum access to the greatest audience of scholars and to obtain as much access as possible to the work of their peers so that they can build on it. the protagonists are thwarted in their attempts to achieve their ends by avaricious publishers who obtain the work of researchers for free and then sell it back to them in the form of journal and database subscriptions and books for exorbitant prices. these prices far exceed the rate of inflation or the budgets of universities to pay for them. the publishers engage in a series of mergers and acquisitions that swallow up small publishing firms and result in the scholarly publishing enterprise being controlled by a few giant firms that offer unreasonable terms to users and make unreasonable demands when negotiating with them. presented in this dramatic way, the significance of scholar participation in digital repositories becomes magnified to an extent that it becomes more difficult to resist what may almost seem like an epic struggle between good and evil. and while this may be a greatly oversimplified example, it nonetheless provides a sense of the potential power of using a narrative approach as a technique to reduce resistance. introducing a time element into the attempt to persuade users to deposit their work in digital repositories can play an important role in reducing resistance. given that faculty are highly competitive, introducing the idea not only that other faculty are submitting their work but that they are already benefiting as a result makes the their behavior in the desired direction. redefinition, consistency, and depersonalization another strategy that psychologists use to reduce resistance among users is to change the definition of the situation. resistant users see the process of submitting their research to the repository as an imposition at best. in their view, the last thing that they need is another obligation or responsibility to burden their already busy lives. psychologists have learned that reframing a situation can reduce resistance by encouraging the user to look at the same phenomenon in a different way. in the current situation, resistant users should be informed that depositing their work in a digital repository is not a burden but a way to raise their professional profile as researchers, to expose their work to a wider audience, and to heighten their visibility among not only their peers but a much larger potential audience that would be able to encounter their work on the web. seen in this way, the additional work of submission is less of a distraction and more of a career investment. moreover, this approach leverages a related psychological concept that can be useful in helping to dissolve resistance. psychologists understand that inconsistency has a negative effect on self-esteem, so persuading users to believe that submitting their work to a digital repository is consistent with their past behavior can be motivating.26 the point needs to be emphasized with researchers that the act of submitting their work to a digital repository is not something strange and radical, but is consistent with prior actions intended to publicize and promote their work. a digital repository can be seen as analogous to a preprint, book, journal, or other tangible and familiar vehicles that faculty have used countless times to send their work out into the world. while the medium might have changed, the intention and the goal are the same. reframing the act of depositing as “old wine in new bottles” may help to undermine resistance. in approaching highly resistant individuals, psychologists have discovered that it is essential to depersonalize any appeal to change their behavior. instead of saying, “you should reduce your caloric intake,” it is better to say, “it is important for people to reduce their caloric intake.” this helps to deflect and reduce the directive, judgmental, and prescriptive quality of the request, thus making it less likely to provoke resistance.27 suggestion can be much less threatening than prescription among users who may be suspicious and mistrusting. reverting to a third-person level of appeal may allow the message to get through without it being immediately rejected by the user. narrative, timing, and anticipation psychologists recommend another strategy to help defuse reducing psychological resistance to digital repositories | quinn 73 technological platforms, and so on. this could be followed by a reminder to users that it is their choice—it is entirely up to them. this reminder that users have the freedom of choice may help to further counter any resistance generated as a result of instructions or inducements to anticipate regret. indeed, psychologists have found that reinstating a choice that was previously threatened can result in greater compliance than if the threat had never been introduced.32 offering users the freedom to choose between alternatives tends to make them more likely to comply. this is because having a choice enables users to both accept and resist the request rather than simply focus all their resistance on a single alternative. when presented with options, the user is able to satisfy the urge to resist by rejecting one option but is simultaneously motivated to accept another option; the user is aware that there are benefits to complying and wants to take advantage of them but also wants to save face and not give in. by being offered several alternatives that nonetheless all commit to a similar outcome, the user is able to resist and accept at the same time.33 for example, one alternative option to self-archiving might be to present the faculty member with the option of an authorpays publishing model. the choice of alternatives allows the faculty member to be selective and discerning so that a sense of satisfaction is derived from the ability to resist by rejecting one alternative. at the same time, the librarian is able to gain compliance because one of the other alternatives that commits the faculty member to depositing research is accepted. options, comparisons, increments, and guarantees in addition to offering options, another way to erode user resistance to digital repositories is to use a comparative strategy. one technique is to first make a large request, such as “we would like you to submit all the articles that you have published in the last decade to the repository,” and then follow this with a more modest request, such as “we would appreciate it if you would please deposit all the articles you have published in the last year.” the original request becomes an “anchor” or point of reference in the mind of the user against which the subsequent request is then evaluated. setting a high anchor lessens user resistance by changing the user’s point of comparison of the second request from nothing (not depositing any work in the repository) to a higher value (submitting a decade of work). in this way, a high reference anchor is established for the second request, which makes it seem more reasonable in the newly created context of the higher value.34 the user is thus more likely to comply with the second request when it is framed in this way. using this comparative approach may also work because it creates a feeling of reciprocity in the user. when proposition much more salient. it not only suggests that submitting work is a process that results in a desirable outcome, but that the earlier one’s work is submitted, the more recognition will accrue and the more rapidly one’s career will advance.29 faculty may feel compelled to submit their work in an effort to remain competitive with their colleagues. one resource that may be particularly helpful for working with skeptical faculty who want substantiation about the effect of self-archiving on scholarly impact is a bibliography created by the open citation project titled, “the effect of open access and downloads (hits) on citation impact: a bibliography of studies.”30 it provides substantial documentation of the effect that open access has on scholarly visibility. an additional stimulus might be introduced in conjunction with the time element in the form of a download report. showing faculty how downloads accumulate over time is analogous to arguments that investment counselors use showing how interest on investments accrues and compounds over time. this investment analogy creates a condition in which hesitating to submit their work results in faculty potentially losing recognition and compromising their career advancement. an interesting related finding by psychologists suggests that an effective way to reduce user resistance is to have users think about the future consequences of complying or not complying. in particular, if users are asked to anticipate the amount of future regret they might experience for making a poor choice, this can significantly reduce the amount of resistance to complying with a request. normally, users tend not to ruminate about the possibility of future disappointment in making a decision. if users are made to anticipate future regret, however, they will act in the present to try to minimize it. studies conducted by psychologists show that when users are asked to anticipate the amount of future regret that they might experience for choosing to comply with a request and having it turn out adversely versus choosing to not comply and having it turn out adversely, they consistently indicate that they would feel more regret if they did not comply and experienced negative consequences as a result.31 in an effort to minimize this anticipated regret, they will then be more prone to comply. based on this research, one strategy to reduce user resistance to digital repositories would be to get users to think about the future, specifically about future regret resulting from not cooperating with the request to submit their work. if they feel that they might experience more regret in not cooperating than in cooperating, they might then be more inclined to cooperate. getting users to think about the future could be done by asking users to imagine various scenarios involving the negative outcomes of not complying, such as lost opportunities for recognition, a lack of citation by peers, lost invitations to collaborate, an inability to migrate one’s work to future 74 information technology and libraries | june 2010 submit their work. mandates rely on authority rather than persuasion to accomplish this and, as such, may represent a less-than-optimal solution to reducing user resistance. mandates represent a failure to arrive at a meeting of the minds of advocates of open access, such as librarians, and the rest of the intellectual community. understanding the psychology of resistance is an important prerequisite to any effort to reduce it. psychologists have assembled a significant body of research on resistance and how to address it. some of the strategies that the research suggests may be effective, such as discussing resistance itself with users and talking about the negative effects of repositories, may seem counterintuitive and have probably not been widely used by librarians. yet when other more conventional techniques have been tried with little or no success, it may make sense to experiment with some of these approaches. particularly in the academy, where reason is supposed to prevail over authority, incorporating resistance psychology into a program aimed at soliciting faculty research seems an appropriate step before resorting to mandates. most strategies that librarians have used in trying to persuade faculty to submit their work have been conventional. they are primarily of a cognitive nature and are variations on informing and educating faculty about how repositories work and why they are important. researchers have an important affective dimension that needs to be addressed by these appeals, and the psychological research on resistance suggests that a strictly rational approach may not be sufficient. by incorporating some of the seemingly paradoxical and counterintuitive techniques discussed earlier, librarians may be able to penetrate the resistance of researchers and reach them at a deeper, less rational level. ideally, a mixture of rational and less-conventional approaches might be combined to maximize effectiveness. such a program may not eliminate resistance but could go a long way toward reducing it. future studies that test the effectiveness of such programs will hopefully be conducted to provide us with a better sense of how they work in real-world settings. references 1. charles w. bailey jr., “institutional repositories: doa?,” online posting, digital koans, aug. 22, 2007,

request from the large one to a smaller one, it creates a sense of obligation on the part of the user to also make a concession by agreeing to the more modest request. the cultural expectation of reciprocity places the user in a situation in which they will comply with the lesser request to avoid feelings of guilt.35 for the most resistant users, breaking the request down into the smallest possible increment may prove helpful. by making the request seem more manageable, the user is encouraged to comply. psychologists conducted an experiment to test whether minimizing a request would result in greater cooperation. they went door-to-door, soliciting contributions to the american cancer society, and received donations from 29 percent of households. they then made additional solicitations, this time asking, “would you contribute? even a penny will help!” using this approach, donations increased to 50 percent. even though the solicitors only asked for a penny, the amounts of the donations were equal to that of the original request. by asking for “even a penny,” the solicitors made the request appear to be more modest and less of a target of resistance.36 librarians might approach faculty by saying “if you could even submit one paper we would be grateful,” with the idea that once faculty make an initial submission they will be more inclined to submit more papers in the future. one final strategy that psychological research suggests may be effective in reducing resistance to digital repositories is to make sure that users understand that the decision to deposit their work is not irrevocable. with any new product, users have fears about what might happen if they try it and they are not satisfied with it. not knowing the consequences of making a decision that they may later regret fuels reluctance to become involved with it. faculty need to be reassured that they can opt out of participating at any time and that the repository sponsors will guarantee this. this guarantee needs to be repeated and emphasized as much as possible in the solicitation process so that faculty are frequently reminded that they are entering into a decision that they can reverse if they so decide. having this reassurance should make researchers much less resistant to submitting their work, and the few faculty who may decide that they want to opt out are worth the reduction in resistance.37 the digital repository is a new phenomenon that faculty are unfamiliar with, and it is therefore important to create an atmosphere of trust. the guarantee will help win that trust. ■■ conclusion the scholarly literature on digital repositories has given little attention to the psychology of resistance. yet the ultimate success of digital repositories depends on

information on the internet be organized? this question and the possible solutions spark debates among people concerned with how we identify, classify, and retrieve internet content. this paper discusses the benefits and the controversies of using a tagging system to organize internet resources. tagging refers to a classification system where individual internet users apply labels, or tags, to digital resources. tagging increased in popularity with the advent of web 2.0 applications that encourage interaction among users. as more information is available digitally, the challenge to find an organizational system scalable to the internet will continue to require forward thinking. trained to ensure access to a range of informational resources, librarians need to be concerned with access to internet content. librarians can play a pivotal role by advocating for a system that supports the user at the moment of need. tagging may just be the necessary system. w ho will organize the information available on the internet? how will it be organized? does it need an organizational scheme at all? in 1998, thomas and griffin asked a similar question, “who will create the metadata for the internet?” in their article with the same name.1 ten years later, this question has grown beyond simply supplying metadata to assuring that at the moment of need, someone can retrieve the information necessary to answer their query. given new classification tools available on the internet, the time is right to reassess traditional models, such as controlled vocabularies and taxonomies, and contrast them with folksonomies to understand which approach is best suited for the future. this paper gives particular attention to delicious, a social networking tool for generating folksonomies. the amount of information available to anyone with an internet connection has increased in part because of the internet’s participatory nature. users add content in a variety of formats and through a variety of applications to personalize their web experience, thus making internet content transitory in nature and challenging to lock into place. the continual influx of new information is causing a rapid cultural shift, more rapid than many people are able to keep up with or anticipate. conversations on a range of topics that take place using web technologies happen in real time. unless you are a participant in these conversations and debates using web-based communication tools, changes are passing you by. internet users in general have barely grasped the concept of web 2.0 and already the advanced “internet cognoscenti” write about web 3.0.2 regarding the organization and availability of internet content, librarians need to be ahead of the crowd as the voice who will assure content will be readily accessible to those that seek it. internet users actively participating in and shaping the online communities are, perhaps unintentionally, influencing how those who access information via the internet expect to be able to receive and use digital resources. librarians understand that the way information is organized is critical to its accessibility. they also understand the communities in which they operate. today, librarians need to be able to work seamlessly among the online communities, the resources they create, and the end user. as internet use evolves, librarians as information stakeholders should stay abreast of web 2.0 developments. by positioning themselves to lead the future of information organization, librarians will be able to select the best emerging web-based tools and applications, become familiar with their strengths, and leverage their usefulness to guide users in organizing internet content. shirky argues that the internet has allowed new communities to form. primarily online, these communities of internet users are capable of dramatically changing society both onand offline. shirky contends that because of the internet, “group action just got easier.”3 according to shirky, we are now at the critical point where internet use, while dependent on technology, is actually no longer about the technology at all. the web today (web 2.0) is about participation. “this [the internet] is a medium that is going to change society.”4 lessig points out that content creators are “writing in the socially, culturally relevant sense for the 21st century and to be able to engage in this writing is a measure of your literacy in the 21st century.”5 it is significant that creating content is no longer reserved for the internet cognoscenti. internet users with a variety of technological skills are participating in web 2.0 communities. information architects, web designers, librarians, business representatives, and any stakeholder dependent on accessing resources on the internet have a vested interest in how internet information is organized. not only does the architecture of participation inherent in the internet encourage completely new creative endeavors, it serves as a platform for individual voices as demonstrated in marijke a. visser (marijkea@gmail.com) is a library and information science graduate student at indiana university, indianapolis, and will be graduating may 2010. she is currently working for ala’s office for information and technology policy as an information technology policy analyst, where her area of focus includes telecommunications policy and how it affects access to information. tagging: an organization scheme for the internet | visser 35 personal and organizationally sponsored blogs: lessig 2.0, boing boing, open access news, and others. these internet conversations contribute diverse viewpoints on a stage where, theoretically, anyone can access them. web 2.0 technologies challenge our understanding of what constitutes information and push policy makers to negotiate equitable internet-use policies for the public, the content creators, corporate interests, and the service providers. to maintain an open internet that serves the needs of all the players, those involved must embrace the opportunity for cultural growth the social web represents. for users who access, create, and distribute digital content, information is anything but static; nor is using it the solitary endeavor of reading a book. its digital format makes it especially easy for people to manipulate it and shape it to create new works. people are sharing these new works via social technologies for others to then remix into yet more distinct creative work. communication is fundamentally altered by the ability to share content on the internet. today’s internet requires a reevaluation of how we define and organize information. the manner in which digital information is classified directly affects each user’s ability to access needed information to fully participate in twenty-first-century culture. new paradigms for talking about and classifying information that reflect the participatory internet are essential. n background the controversy over organizing web-based information can be summed up comparing two perspectives represented by shirky and peterson. both authors address how information on the web can be most effectively organized. in her introduction, peterson states, “items that are different or strange can become a barrier to networking.”6 shirky maintains, “as the web has shown us, you can extract a surprising amount of value from big messy data sets.”7 briefly, in this instance ontology refers to the idea of defining where digital information can and should be located (virtually). folksonomy describes an organizational system where individuals determine the placement and categorization of digital information. both terms are discussed in detail below. although any organizational system necessitates talking about the relationship(s) among the materials being organized, the relationships can be classified in multiple ways. to organize a given set of entities, it is necessary to establish in what general domain they belong and in what ways they are related. applying an ontological, or hierarchical, classification system to digital information raises several points to consider. first, there are no physical space restrictions on the internet, so relationships among digital resources do not need to be strictly identified. second, after recognizing that internet resources do not need the same classification standards as print material, librarians can begin to isolate the strengths of current nondigital systems that could be adapted to a system for the internet. third, librarians must be ready to eliminate current systems entirely if they fail to serve the needs of internet users. traditional systems for organizing information were developed prior to the information explosion on the internet. the internet’s unique platform for creating, storing, and disseminating information challenges pre– digital-age models. designing an organizational system for the internet that supports creative innovation and succeeds in providing access to the innovative work is paramount to moving the twenty-first-century culture forward. n assessing alternative models controversy encourages scrutiny of alternative models. in understanding the options for organizing digital information, it is important to understand traditional classification models. smith discusses controlled vocabularies, taxonomies, and facets as three traditional methods for applying metadata to a resource. according to smith, a controlled vocabulary is an unambiguous system for managing the meanings of words. it links synonyms, allowing a search to retrieve information on the basis of the relationship between synonyms.8 taxonomies are hierarchical, controlled vocabularies that establish parent–child relationships between terms. a faceted classification system categorizes information using the distinct properties of that information.9 in such a system, information can exist in more than one place at a time. a faceted classification system is a precursor to the bottom-up system represented by folksonomic tagging. folksonomy, a term coined in 2004 by thomas vander wal, refers to a “user-created categorical structure development with an emergent thesaurus.”10 vander wal further separates the definition into two types: a narrow and a broad folksonomy.11 in a broad folksonomy, many people tag the same object with numerous tags or a combination of their own and others’ tags. in a narrow folksonomy, one or few people tag an object with primarily singular terms. internet searching represents a unique challenge to people wanting to organize its available information. search engines like yahoo! and google approach the chaotic mass of information using two different techniques. yahoo! created a directory similar to the file folder system with a set of predetermined categories that were intended to be universally useful. in so doing, the yahoo! developers made assumptions about how the general public would categorize and access information. the categories 36 information technology and libraries | march 2010 and subsequent subcategories were not necessarily logically linked in the eyes of the general public. the yahoo! directory expanded as internet content grew, but the digital folder system, like a taxonomy, required an expert to maintain. shirky notes the yahoo! model could not scale to the internet. there are too many possible links to be able to successfully stay within the confines of a hierarchical classification system. additionally, on the internet, the links are sufficient for access because if two items are linked at least once, the user has an entry point to retrieve either one or both items.12 a hierarchical system does not assure a successful internet search and it requires a user to comprehend the links determined by the managing expert. in the google approach, developers acknowledged that the user with the query best understood the unique reasoning behind her search. the user therefore could best evaluate the information retrieved. according to shirky, the google model let go of the hierarchical file system because developers recognized effective searching cannot predetermine what the user wants. unlike yahoo!, google makes the links between the query and the resources after the user types in the search terms.13 trusting in the link system led google to understand and profit from letting the user filter the search results. to select the best organizational model for the internet it is critical to understand its emergent nature. a model that does not address the effects of web 2.0 on internet use and fails to capture participant-created content and tagging will not be successful. one approach to organizing digital resources has been for users to bookmark websites of personal interest. these bookmarks have been stored on the user’s computer, but newer models now combine the participatory web with saving, or tagging, websites. social bookmarking typifies the emergent web and the attraction of online networking. innovative and controversial, the folksonomy model brings to light numerous criteria necessary for a robust organizational system. a social bookmarking network, delicious is a tool for generating folksonomies. it combines a large amount of self-interest with the potential for an equal, if not greater, amount of social value. delicious users add metadata to resources on the internet by applying terms, or tags, to urls. users save these tagged websites to a personal library hosted on the delicious website. the default settings on delicious share a user’s library publicly, thus allowing other people—not limited to registered delicious account holders—to view any library. that the delicious developers understood how internet users would react to this type of interactive application is reflected in the popularity of delicious. delicious arrived on the scene in 2003, and in 2007 developers introduced a number of features to encourage further user collaboration. with a new look (going from the original del.icio.us to its current moniker, delicious) as well as more ways for users to retrieve and share resources by 2007, delicious had 3 million registered users and 100 million unique urls.14 the reputation of delicious has generated interest among people concerned with organizing the information available via the internet. how does the folksonomy or delicious model of open-ended tagging affect searching, information retrieving, and resource sharing? delicious, whose platform is heavily influenced by its users, operates with no hierarchical control over the vocabulary used as tags. this underscores the organization controversy. bottom-up tagging gives each person tagging an equal voice in the categorization scheme that develops through the user generated tags. at the same time, it creates a chaotic information-retrieval system when compared to traditional controlled vocabularies, taxonomies, and other methods of applying metadata.15 a folksonomy follows no hierarchical scheme. every tag generated supplies personal meaning to the associated url and is equally weighted. there will be overlap in some of the tags users select, and that will be the point of access for different users. for the unique tags, each delicious user can choose to adopt or reject them for their personal tagging system. either way, the additional tags add possible future access points for the rest of the user community. the social usefulness of the tags grows organically in relationship to their adoption by the group. can the internet support an organizational system controlled by user-generated tags? by the very nature of the participatory web, whose applications often get better with user input, the answer is yes. delicious and other social tagging systems are proving that their folksonomic approach is robust enough to satisfy the organizational needs of their users. defined by vander wal, a broad folksonomy is a classification system scalable to the internet.16 the problem with projecting already-existing search and classification strategies to the internet is that the internet is constantly evolving, and classic models are quickly overcome. even in the nonprint world of the internet, taxonomies and controlled vocabulary entail a commitment both from the entity wanting to organize the system and the users who will be accessing it. developing a taxonomy involves an expert, which requires an outlay of capital and, as in the case with yahoo!, a taxonomy is not necessarily what users are looking for. to be used effectively, taxonomies demand a certain amount of user finesse and complacency. the user must understand the general hierarchy and by default must suspend their own sense of category and subcategory if they do not mesh with the given system. the search model used by google, where the user does the filtering, has been a significantly more successful search engine. google recognizes natural language, making it user friendly; however, it remains merely a search engine. it is successful at making links, but it leaves the user stranded without a means to organize search results beyond simple page rank. traditional tagging: an organization scheme for the internet | visser 37 hierarchical systems and search strategies like those of yahoo! and google neglect to take into account the tremendous popularity of the participatory web. successful web applications today support user interaction; to disregard this is naive and short-sighted. in contrast to a simple page-rank results list or a hierarchical system, delicious results provide the user with rich, multilayer results. figure 1 shows four of the first ten results of a delicious search for the term “folksonomy.” the articles by the four authors in the left column were tagged according to the diagram. two of the articles are peer-reviewed, and two are cited repeatedly by scholars researching tagging and the internet. in this example, three unique terms are used to tag those articles, and the other terms provide additional entry points for retrieval. further information available using delicious shows that the guy article was tagged by 1,323 users, the mathes article by 2,787 users, the shirky article by 4,383 users, and the peterson article by 579 users.17 from the basic delicious search, the user can combine terms to narrow the query as well as search what other users have tagged with those terms. similar to the card catalog, where a library patron would often unintentionally find a book title by browsing cards before or after the actual title she originally wanted, a delicious user can browse other users’ libraries, often finding additional pertinent resources. a user will return a greater number of relevant and automatically filtered results than with an advanced google search. as an ancillary feature, once a delicious user finds an attractive tag stream—a series of tags by a particular user—they can opt to follow the user who created the tag stream, thereby increasing their personal resources. hence delicious is effective personally and socially. it emulates what internet users expect to be able to do with digital content: find interesting resources, personalize them, in this case with tags, and put them back out for others to use if they so choose. proponents of folksonomy recognize there are benefits to traditional taxonomies and controlled vocabulary systems. shirky delineates two features of an organizational system and their characteristics, providing an example of when a hierarchical system can be successful (see table 1).18 these characteristics apply to situations using databases, journal articles, and dissertations as spelled out by peterson, for example.19 specific organizations with identifiable common terminology—for example, medical libraries—can also benefit from a traditional classification system. these domains are the antithesis of the domain represented by the web. the success of controlled vocabularies, taxonomies, and their resulting systems depends on broad user adoption. that, in combination with the cost of creating and implementing a controlled system, raises questions as to their utility and long-term viability for use on the web. though meant for longevity, a taxonomy fulfills a need at one fixed moment in time. a folksonomy is never static. taxonomies developed by experts have not yet been able to be extended adequately for the breadth and depth of internet resources. neither have traditional viewpoints been scaled to accept the challenges encountered in trying to organize the internet. folksonomy, like taxonomy, seeks to provide the information critical to the user at the moment of need. folksonomy, however, relies on users to create the links that will retrieve the desired results. doctorow puts forward three critiques of a hierarchical metadata system, emphasizing the inadequacies of applying traditional classification schemes to the digital stage: 1. there is not a “correct” way to categorize an idea. 2. competing interests cannot come to a consensus figure 1. search results for “folksonomy” using delicious. table 1. domains and their participants domain to be organized participants in the domain small corpus expert catalogers formal categories authoritative source of judgment restricted entities coordinated users clear edges expert users 38 information technology and libraries | march 2010 on a hierarchical vocabulary. 3. there is more than one way to describe something. doctorow elaborates: “requiring everyone to use the same vocabulary to describe their material denudes the cognitive landscape, enforces homogeneity in ideas.”20 the internet raises the level of participation to include innumerable voices. the astonishing thing is that it thrives on this participation. guy and tonkin address the “folksonomic flaw” by saying user-generated tags are by definition imprecise. they can be ambiguous, overly personal, misspelled, and a contrived compound word. guy and tonkin suggest the need to improve tagging by educating the users or by improving the systems to encourage more accurate tagging.21 this, however, does not acknowledge that successful web 2.0 applications depend on the emergent wisdom of the user community. the systems permit organic evolution and continual improvement by user participation. a folksonomy evolves much the way a species does. unique or single-use tags have minimal social import and do not gain recognition. tags used by more than a few people reinforce their value and emerge as the more robust species. n conclusion the benefits of the internet are accessible to a wide range of users. the rewards of participation are immediate, social, and exponential in scope. user-generated content and associated organization models support the internet’s unique ability to bring together unlikely social relationships that would not necessarily happen in another milieu. to paraphrase shirky and lessig, people are participating in a moment of social and technological evolution that is altering traditional ways of thinking about information, thereby creating a break from traditional systems. folksonomic classification is part of that break. its utility grows organically as users add tagged content to the system. it is adaptive, and its strengths can be leveraged according to the needs of the group. while there are “folksonomic flaws” inherent in a bottomup classification system, there is tremendous value in weighting individual voices equally. following the logic of web 2.0 technology, folksonomy will improve according to the input of the users. it is an organizational system that reflects the basic tenets of the emergent internet. it may be the only practical solution in a world of participatory content creation. shirky describes the internet by saying, “there is no shelf in the digital world.”22 classic organizational schemes like the dewey decimal system were created to organize resources prior to the advent of the internet. a hierarchical system was necessary because there was a physical limitation on where a resource could be located; a book can only exist in one place at one time. in the digital world, the shelf is simply not there. material can exist in many different places at once and can be retrieved through many avenues. a broad folksonomy supports a vibrant search strategy. it combines individual user input with that of the group. this relationship creates data sets inherently meaningful to the community of users seeking information on any given topic at any given moment. this is why a folksonomic approach to organizing information on the internet is successful. users are rewarded for their participation, and the system improves because of it. folksonomy mirrors and supports the evolution of the internet. librarians, trained to be impartial and ethically bound to assure access to information, are the logical mediators among content creators, the architecture of the web, corporate interests, and policy makers. critical conversations are no longer happening only in traditional publications of the print world. they are happening with communication platforms like youtube, twitter, digg, and delicious. information organization is one issue on which librarians can be progressive. dedicated to making information available, librarians are in a unique position to take on challenges raised by the internet. as the profession experiments with the introduction of web 3.0, librarians need to position themselves between what is known and what has yet to evolve. librarians have always leveraged the interests and needs of their users to tailor their services to the individual entry point of every person who enters the library. because more and more resources are accessed via the internet, librarians will have to maintain a presence throughout the web if they are to continue to speak for the informational needs of their users. part of that presence necessitates an ability to adapt current models to the internet. more importantly, it requires recognition of when to forgo conventional service methods in favor of more innovative approaches. working in concert with the early adopters, corporate interests, and general internet users, librarians can promote a successful system for organizing internet resources. for the internet, folksonomic tagging is one solution that will assure users can retrieve information necessary to answer their queries. references and notes 1. charles f. thomas and linda s. griffin, “who will create the metadata for the internet?” first monday 3, no. 12 (dec. 1998). 2. web 2.0 is a fairly recent term, although now ubiquitous among people working in and around internet technologies. attributed to a conference held in 2004 between medialive tagging: an organization scheme for the internet | visser 39 international and o’reilly media, web 2.0 refers to the web as being a platform for harnessing the collective power of internet users interested in creating and sharing ideas and information without mediation from corporate, government, or other hierarchical policy influencers or regulators. web 3.0 is a much more fluid concept as of this writing. there are individuals who use it to refer to a semantic web where information is analyzed or processed by software designed specifically for computers to carry out the currently human-mediated activity of assigning meaning to information on a webpage. there are librarians involved with exploring virtual-world librarianship who refer to the 3d environment as web 3.0. the important point here is that what internet users now know as web 2.0 is in the process of being altered by individuals continually experimenting with and improving upon existing web applications. web 3.0 is the undefined future of the participatory internet. 3. clay

2014–2020 meris mandernach longmeier information technology and libraries | december 2021 https://doi.org/10.6017/ital.v40i4.13389 meris mandernach longmeier (longmeier.10@osu.edu) is head of research services, the ohio state university libraries. © 2021. abstract libraries foster a thriving campus culture and function as “third space,” not directly tied to a discipline.1 libraries support both formal and informal learning, have multipurpose spaces, and serve as a connection point for their communities. for these reasons, they are an ideal location for events, such as hackathons, that align with library priorities of outreach, data and information literacy, and engagement focused on social good. hackathon planners could find likely partners in either academic or public libraries as their physical spaces accommodate public outreach events and many are already providing similar services, such as makerspaces. libraries can act solely as a host for events or they can embed in the planning process by building community partnerships, developing themes for the event, or harnessing the expertise already present in the library staff. this article, focusing on years from 2014 to 2020, will highlight the history and evolution of hackathons in libraries as outreach events and as a focus for using library materials, data, workflows, and content. introduction as a means of introduction to hackathons for those unfamiliar with these events, the following definition was developed after reviewing the literature. hackathons are time-bound events where participants gather to build technology projects, learn from each other and experts, and create innovative solutions that are often judged for prizes. while hacking can have negative connotations when it comes to security vulnerabilities, typically for hackathon events hacking refers to modifying original lines of code or devices with the intent of creating a workable prototype or product. events may have a specific theme (use of a particular dataset or project based on a designated platform) or may be open-ended with challenges focused on innovation or social good. while hackathons have been a staple in software and hardware design for decades, the first hackathons with a library focus were sponsored by vendors, focused on topics such as accessibility and adaptive technology for their content and platforms.2 other industry hackathons focused on re-envisioning the role of the book in 2013 and 2014.3 as hackathons became more popular at colleges and universities, library participation evolved from content provider to event host. these partnerships were beneficial to libraries interested in shifting the perception of libraries from books to newer areas of expertise around data and information literacy. however, many libraries realized that by partnering in planning the events greater possibilities existed to educate participants about library content and staff expertise. some examples include working with public library communities to highlight text as data, having academic subject librarians work with departmental faculty to embed events within curriculum and assignments, and for both academic and public libraries to promote library-produced and publicly available datasets.4 information technology and libraries december 2021 hackathons and libraries |longmeier 2 there are many roles that libraries can take in these events. libraries can act as event hosts where they provide the space at a cost or for free.5 in other cases, library staff become collaborators and in addition to space may assist with planning logistics, judging, building partnerships, and have some staff present at the events.6 in public libraries this often includes building relationships with the city or specific segments of the community based on the theme of the event. on college campuses, it may be a partnership with a specific disciplines or campus it or an outside sponsor. in this way, the libraries are building and sustaining the event due to aligned priorities with the other partners. another option would be for the library to be the primary sponsor, where the library may provide prizes, the theme for the hackathon, as well as many of the items listed above.7 however, instead of specific categories, it should be viewed as a continuum of partnership and the amount of involvement with the event should align with the library’s priorities of what it hopes to accomplish through the event. how involved in event planning specific libraries want to be may depend on the depth of the existing partnerships as well as how many resources the library wants to commit to the event. libraries have always existed as curators and distributors of knowledge. some libraries are using hackathons to advance both their image and their practices. libraries are evolving into new roles and have grown to support more creative endeavors, such as the maker movement. this shift of libraries from book-provider to social facilitator and information co-creator aligns with hackathon events. the physical spaces themselves are ideal to support public outreach events and libraries are already providing makerspaces or similar services that would overlap with a hackathon audience.8 additionally, the spaces afforded by libraries allow flexibility and creativity to flourish, ideas to be exchanged, and different disciplines to mingle and co-produce. library staff focused on software development may have projects that would benefit from outside perspectives as well. in recent years libraries have become stewards of digital collections that can be used and reused in innovative ways. many libraries have chosen wikipedia edit-a-thons as a means of engaging with the public and enhancing access to materials.9 similarly, the collections-as-data movement is blossoming and allowing galleries, libraries, archives, and museum (glam) institutions to rethink the possible ways of interacting with collections. many public libraries are partnering with local or regional governments to build awareness of data sources and build bridges with the community around how they would like to interact with the data.10 additionally, as data science continues to grow in importance in both public and academic libraries, data fluency, data cleaning, and data visualization could be themes for a hackathon or data-thon.11 for those unfamiliar with these events, table 1 provides some generalized definitions created by the author of the different types of events and their intended purpose. for some organizations, there are ways to support these events that consume fewer resources or require less technical knowledge, such as an edit-a-thons or code jams. information technology and libraries december 2021 hackathons and libraries |longmeier 3 table 1. defining common hackathon and hackathon-like events, purpose, and typical size of events type of event definition purpose size of event hackathon a team-based sprint-like event focused on hardware or software that brings together programmers, graphic designers, interface designers, project managers or domain experts; can be open ended idea generation or for a specific provided theme build a working prototype, typically software up to 1,000 participants, usually determined by space available idea fest business pitch competition where individuals or teams pitch a solution or new company (startup) idea to a panel of judges deliver an elevator pitch for an idea, could be to secure funding <100 coding contest or code jam an individual or team competition to work through algorithmic puzzles or on specific code provided learning to code or solve challenges through coding; may produce a pitch at the end rather than a product 20–50 edit-athon an event where users improve content in a specific online community; can focus on a theme (art, country, city) or type of material (map) improving information in online communities such as wikipedia, openstreetmap, or localwiki 20–100 datathon a data-science–focused event where participants are given a dataset and a limited amount of time to test, build, and explore solutions usually a visualization or software development around a particular dataset 50–100 makeathon hardware focused hackathon build working prototype of hardware up to 300 participants methods to find articles in the library and information science literature related to hackathons and libraries, the author searched the association for computing machinery (acm) digital library, scopus, library literature and information science, and library and information science and technology abstracts (lista) databases. in scopus and the acm digital library, the most successful searches included the following: (hackathon* or makeathon*) and library; in library literature and information science and lista databases, the most successful searches included: information technology and libraries december 2021 hackathons and libraries |longmeier 4 hackathon or makeathon or “coding contest.” the author also searched google scholar in an attempt to locate other studies or reports, some of which came from institutional repositories. while this search strategy was not meant to be exhaustive, it uncovered many articles about hackathons and libraries and others were found by chaining citations in the articles reference lists. based on search locales, international articles were found but only those where the text was available in english were included which meant that articles from asia, africa, and the global south may have been inadvertently overlooked. only two of the articles found in the search results were not held in library locations, did not use library/archival materials, or were not an outreach event where library staff were integral in planning (these were discarded.) findings the author grouped the literature into two categories: library as place and library as source. in the realm of library as place, the literature consisted of reporting on hackathons where the library was the host location for the event, those where the hackathon was an outreach event, and those where the hackathon was an extension of the libraries’ teaching/education mission. for most of these articles the majority were case studies and often shared tips for other libraries to consider when hosting a hackathon in library spaces. the second category, those that use library as source, focused on highlighting library spaces or services, workflows, or collections as the theme of the events. additionally, there were a few articles in the second category that discussed how to prepare or clean library data or library sources before the event to ensure that participants were able to use the materials during the time-bound event. in some cases where the source materials were from the libraries, the event also occurred in the library; thus, some articles fit into both categories and are highlighted in both sections. results: library as place the following summaries of hackathons and libraries as places for events will be grouped into two subgenres: library spaces and outreach events. libraries, both public and academic, are ideal locations for hosting large, technology-driven events given the usual amenities of ample parking, ubiquitous wi-fi, adequate outlets, and at times already having 24-hour spaces built into their infrastructure. more and more libraries are offering generous food and drink policies, a benefit as sustenance is a mainstay at these multiday events. additionally, libraries already host a number of outreach events and serve as a community information hub. using libraries as event hosts for hackathons a number of articles detail the use of library spaces to host hackathon events.12 the university of michigan library, a local hackerspace (all hands active), and the ann arbor district library teamed up to host a hackathon focused on oculus rift.13 this event grew out of a larger partnership with the community and sought to mix teams to include participants from all three areas. the 2018 article by demeter et al. highlights lessons learned from florida state university library and many of the planning steps involved when hosting large outreach events in library spaces.14 while the library initially hosted a 36-hour event, hackfsu, as a favor to the provost in the first year, they continue to host the event, providing library staff as mentors and logistical support. after the first year they started charging the student organization for use of the space and direct staffing costs for the hours beyond normal operating hours. while focused primarily on providing a central campus space, the library also sees it as a way to highlight the teaching and learning role of the library. similarly, nandi and mandernach detail the steps involved in planning information technology and libraries december 2021 hackathons and libraries |longmeier 5 hackathon events and some benefits of choosing the library as a location for the event.15 at ohio state, hackathon events in 2014 and 2015 were held in the library due to twenty-four-hour spaces, interest by the libraries in supporting innovative endeavors on campus, and a participant size (100–200 attendees) that could be accommodated in the space. other events chose academic libraries as locations for hackathons due to their central location on campus.16 an initial summary of library hackathons was captured by r. c. davis who detailed that libraries may be motivated to host such events as they align with library principles of “community, innovation, and outreach.”17 she points out that libraries are ideal locations because of small modular workspaces paired with a large space for final presentations. additionally, adequate and sufficiently strong wi-fi or hardwired connections, a multitude of power outlets, and 24-hour spaces are appealing for these kinds of events. event planners should know that the necessities include free food and multidisciplinary involvement. davis details ways to plan smaller events, such as code days or edit-a-thons, if staffing does not allow for a large hackathon event. in all cases, the libraries serve a purpose to either campus or community as the location and sometimes also provide staff for the events. hackathons as library outreach hackathon events are a great way to reach out to the community and provide a fresh look into libraries as purveyors of information focused on more than books. at the 2014 computers in libraries conference, chief library officer mary lee kennedy delivered a keynote sharing stories of the new york public libraries experiences hosting wikipedia editathons and other hackathons at various branches since 2014.18 the goals for these outreach events were to highlight strategic priorities around making knowledge accessible, re-examine the library purpose, and spark connections. early library hackathon events focused on outreach included topics of accessibility or designing library mobile apps.19 more recent events have focused on outreach but with an eye toward sharing content as part of the coding contest.20 even library associations have hosted preconference hacking events to highlight what libraries are doing to foster innovation.21 the future libraries product forge, a four-day event, was hosted in collaboration with the scottish library and information council and delivered by product forge, a company focused on running hackathons that tackle challenging social issues. the 2016 event focused specifically on public libraries in scotland and seven teams, comprised mainly of students from a local university, worked with public library staff and users as well as regional experts in technology, design, and business.22 the goals of the event were to raise awareness of digital innovation with library services, generate enthusiasm for approaches to digital service design, and codesign new services around digital ventures. participants created novel products including digital signage, a game for young readers, a tool for collecting user stories about library services, and an app to reserve specific library spaces. another common focus for library hackathon outreach events is the theme of data and data literacy. in july 2016, the los angeles public library hosted the civic information lab’s immigration hackathon.23 this outreach event gathered 100 participants to address local issues around immigration. the library, motivated by establishing itself as a “welcoming, trusting environment,” wanted to be a “prominent destination of immigrant and life-enrichment information and programs and services.”24 newcastle libraries ran two-day-long events focused on promoting data they released under an open license as part of the commons are forever project.25 they used both events to educate users about tools such as github, a gif-making session with historical photographs, and data visualization tools. similarly, toronto public library hosted a series of open data hackathons to highlight the role of the libraries in civic issue information technology and libraries december 2021 hackathons and libraries |longmeier 6 discourse, data literacy, and data education.26 their events combined the hackathon with other panel presentations and resources focused on mentorship and connection-building in the technology sector. the library also used the event to promote their open data policy, build awareness around the data provided by the library for the community, and highlight their role in facilitating conversations around civic issues through data literacy and data education. edmonton public library hosted its first hackathon in 2014 for international open data day. one of the main drivers was to build the relationship with their local government.27 they built their event around the tenets laid out in the open data hackathon how-to guide and by a blog post about the city of vancouver’s 2013 international open data day hackathon.28 they took a structured approach to documenting expectations of both partners around areas such as resources, staffing, and costs, which served as a roadmap for the hackathon and the partnership. the library provided the event space, coffee and pizza, an emcee, tech help and wi-fi, door prizes and “best idea” prize, and promotional material. the city recruited participants and provided an orientation, promotional banners, and a keynote. the event led to a deeper partnership with the city and additional hacking events. in these ways, the hackathon served a greater purpose of community building and awareness around data, the role the library plays in interpreting data, and how the libraries serve as a resource hub to the community. events supporting library teaching mission at academic institutions, the events often focus on outreach to their own campus community. in 2015, adelphi university hosted their first hackathon and the libraries funded the event themselves rather than seeking outside funding.29 the article details the considerable lessons learned through the process as well as a step-by-step guide to planning a smaller event. similarly, york university science and engineering library hosted hackfests in the library and embedded an event as part of an introductory computer science course.30 shujah highlighted some of the benefits to the library hosting a hackathon included: establishing libraries as part of the research landscape, providing a constructive space for innovation and innate collaborative environment, highlighting the commitment to openness and democratizing knowledge, and acknowledging the library’s role in boosting critical thinking and information literacy concepts. shin, vela, and evans highlight a community hackathon at washington state university college of medicine where a group of librarians from multiple institutions staffed a research station throughout the event.31 while the station was underutilized by participants, as only seven questions were asked during the event, the libraries deemed their participation a success as it worked as an outreach and promotion mechanism for both library services and expertise. at some public libraries, the focus of the hackathon is on education and teaching basic coding skills. whether called a coding contest, hackathon, or tech sandbox, there are opportunities for programming with a focus on learning and skill-building and fun.32 santa clara county library district used a peer-to-peer approach for mentoring and hosted a hackathon in 2015 for middle and high-school students.33 the library staff facilitated the event planning and recruited judges from the community, but the bulk of the event was coordinated by the students. considerations when hosting events in library spaces a couple of substantive reports provide overarching recommendations and considerations for hosting hackathons in library spaces, including planning checklists, tips on getting funding, building partnerships with local community officials, and thinking through the event systematically. recently, the digital public library of america (dpla) created a hackathon information technology and libraries december 2021 hackathons and libraries |longmeier 7 planning guide that details a number of logistical issues to address during the planning phases, both preand post-event.34 this report highlights specific considerations for galleries, libraries, archives and museums that are looking to host a hackathon. after hosting a successful hackathon, librarians at new york university created a libguide called hack your library which is a planning guide for other libraries considering hosting a similar event.35 the engage respond innovate final report: the value of hackathons in public libraries was put together following an event the carnegie uk trust sponsored.36 this guide highlights some of the challenges present with hackathons, including: intellectual property of the creations, prizes, participant diversity, and complications that arise from either approach of using specific themes or open-ended challenges. it also highlights some of the main reasons a library should consider hackathons and other coding events, including ways to promote new roles of libraries within communities, promote specific collections, capitalize on community expertise, gain insight about users, help users build new skills and improve digital literacy, and develop tools that increase access to materials. finally, the report points out that hosting an event will not be the only solution for a library’s innovation problem. yet if the library is clear on why it wants to hold a hackathon, being planful about expectations and outcomes the library is trying to achieve will increase the chances for success. results: library as source the other category of articles about hackathons and libraries focuses on the library as the source for the challenge or theme of the hackathon. the following summaries highlight articles include those where the libraries provided the challenges around library spaces or services, library datasets, workflows or collections as the theme for the hackathon. this section also details steps involved in cleaning data for use/re-use in time-bound events. using hackathons to improve library services and spaces a few articles discuss libraries that proposed hackathon themes around improving library services. a 2016 article describes how adelphi university libraries hosted a hackathon and provided the theme of developing library mobile apps and web software applications.37 the winning student team created an app for library group study meetups. similarly, the librarians from university of illinois tried three approaches for library app development: a student competition, a project in a computer science course, and a coding camp. with the adventure code camp, students co-designed with librarians over the course of two days.38 they advertised to specific departments and courses and ten students were selected with six ultimately participating in the two-day coding camp. students were sent a package of library data, available apis, and brief tutorials on coding languages that may be useful. mentors and coaches were available throughout the coding camp. the authors provided tips for others trying to replicate their approach as well as insights from the students about interest in developing apps that include library data but that don’t solely focus on library services. the following year the librarians hosted a coding contest focused specifically on app development related to library services and spaces.39 the library sponsored the event and served as both a traditional client and partner in the design process. ultimately six teams with a total of 26 individuals participated and each app was “required to address student needs for discovery of and access to information about library services, collections, and/or facilities” but not duplicate existing library mobile apps. they based their approach on massachusetts institute of technology’s entrepreneurship competition. through this process, co-ownership was preferred and many teams set up a licensing agreement as part of the competition to handle intellectual property for the software. students had two weeks to complete the apps and were judged by both library and campus it administration. this article details what information technology and libraries december 2021 hackathons and libraries |longmeier 8 they learned through the process given the amount of attrition from selection of teams to final product presentations. the new york university school of engineering worked with the libraries and used a hackathon theme of noise issues to coincide with the renovation of the library.40 the libraries created a libguide to provide structured information about the event itself (https://guides.nyu.edu/hackdibner). they used the event to market the new maker space and held workshops there leading up to the event. in the inaugural year they held the event over the course of two semesters and saw a lot of attrition due to the event length. in the second year, following focus groups with participants, they designed a library hackathon with four goals: 1) appeal to a large base of the student population, 2) create a triangle of engagement between the student and the library, the library and the faculty, and the faculty and the students, 3) provide an adaptable model to other libraries, and 4) highlight the development of student information literacy skills.41 the second year’s approach required more work by the participants due to pitching an initial concept, providing a written proposal, and giving a final presentation. library staff and guest speakers offered workshops to help students hone their skills. the planners evaluated the event through surveys and student focus groups. overall the students applied what they learned about information literacy and were highly engaged with the codesign approach to library service improvements. similarly, mcgowan highlights two hackathons at purdue that focused on inclusive healthcare and how the libraries applied design thinking processes as part of the events.42 the librarian wanted to encourage health sciences students to examine health data challenges. to examine this issue, she applied the blended librarians adapted addie model (blaam) as a guide to developing a service to prepare students to participate in a hackathon. a number of pre-event training sessions were held in the libraries and covered topics such as research data management, openrefine and data cleaning, gephi for data visualization, and javascript. while this initial approach was in tandem with the hackathon events, students reported that they needed assistance in finding and cleaning datasets for use. in this case, developing library services to prepare for hackathon events ended up out of alignment with both the library’s mission and the participants’ expectations. using library materials for hackathon themes several events have focused on library as source where the library’s materials or processes serve as the theme of the hackathon, particularly around digital humanities (dh) topics.43 in september 2016, over 100 participants worked with materials from the special collections of hamburg state and university library, a space that serves both the university and the public.44 it followed the process established by coding da vinci (https://codingdavinci.de/en), an event that occurred in 2014 and 2015. the event at hamburg state and university library had a kick-off day for sharing available datasets, brainstorming projects using library materials, and team building opportunities. the event had a second day of programming and then teams had six weeks to complete their projects. some exemplary products included a sticker printer that would print old photographs, a quiz app based on engraving plates, and using a social media platform to bring the engravings to the public. the event was successful and resulted in opening additional data from the institution. several examples focus on highlighting digital humanities approaches as part of the events. in 2016, four teams from across european institutions participated over five days in kibbutz lotan in the arava region of israel to develop linguistic tools for tibetan buddhist studies with the goal of information technology and libraries december 2021 hackathons and libraries |longmeier 9 revealing their collections to the public.45 the planning team recruited international scholars to participate in prestructured teams (teams consisted of computer scientists as well as a tibetan scholar) in israel. although it was less of a traditional hackathon, this event being more akin to an event/coding contest around a specific task, it highlighted tools and methods for understanding literary texts. the format of the event for encouraging interdisciplinary efforts in the computational humanities was deemed successful and it was repeated the next year on manuscripts and computer-vision approaches. recently the university of waterloo detailed a series of datathons using archives unleashed to engage the community in an open-source digital humanities project.46 the goal of the events was to engage dh practitioners with the web archive analysis tools and attempt to build a web archiving analysis community. in 2016, the american museum of natural history in new york hosted their third annual hackathon event, hack the stacks, with more than 100 participants.47 the event focused on creating innovative solutions for libraries or archives and to “animate, organize, and enable greater access to the increasing body of digitized content.” ten tasks were available for participants to work on and ranged from a unified search interface, reassembling fragments of scientific notebooks, and creating timelines of archival photos of the museum itself. in addition to planning the tasks, the library staff ensured that the databases and applications could handle the additional traffic. a multitude of platforms were provided (omeka, dspace, the catalog, apis, archivespace, etc) for hackers to use. all prototypes that were developed were open source and deposited on github at “hack the stacks.”48 some cultural institutions have used hackathons as a means of outreach and publicity and then have showcased the outputs at the museums. vhacks, a hackathon at the vatican, was held in 2018 and gathered 24 teams from 30 countries for a 36-hour event.49 the three themes for the event focused on social inclusion, interfaith dialogue, and migrants and refugees. a winner was announced for each thematic area and sponsors enticed participants to continue working on projects by having a venture capitalist pitch a few weeks after the event. another program, museomix, concentrates on a three-day rapid prototyping event where outputs are highlighted in the museum or cultural institution.50 this event has happened annually in november since 2011 and the goal is to create interdisciplinary networks and encourage innovation and community partnership. improving library workflows and processes other hackathons have focused on library staff working on library processes themselves. bergland, davis, and traill detail a two-day event, catdoc hack doc, hosted by the university of minnesota data management and access department focused on increasing documentation by library staff.51 this article details logistics of preparing for the event as well and a summary of the work completed. they based their approach on the islandora collaboration group’s template on how to run a hack/doc.52 they were pleased with the workflow overall, refined some of the steps, and held it again for library staff the following year. similarly, dunsire highlights using a hackathon format to encourage adoption of a cataloging approach of research description and access (rda) through a “jane-athon.”53 events occurred at library conferences or in conjunction with other hackathon events, such as the thing-athon at harvard, with the intention of promoting the use of rda, to help users understand the utility of rda, and to spark discussions. this approach proved useful in uncovering some limitations with rda as well as valuable feedback that could be incorporated into its ongoing development. information technology and libraries december 2021 hackathons and libraries |longmeier 10 considerations when using libraries as source if libraries are interested in hosting a hackathon where the library plays a more central role, there are several options of ready-to-use library and museum data that could allow the host to also serve as the content provider. the digital public library of america released a hackathon guide, glam hack-in-a-box: a short guide for helping you organize a glam hackathon with several sources at the end for finding data related to libraries.54 the university of glasgow began a project called the global history hackathons that seeks to improve access and excitement around global history research.55 additionally, candela et al. detail the new array of sources for sharing glam data for reuse in multiple ways, including using data in hackathon projects.56 planners could look to the collections-as-data conversations for other data sources that could be adapted for hackathon projects.57 when thinking about hackathons and cultural institutions, sustainability of projects and choice of platforms is an important consideration for planners.58 ultimately, the top priority when providing a dataset is to ensure that it is clean and enough details about the dataset are available for participants to make use of it in their designs given the time constraints of most events. discussion hackathons often have a dual purpose of educating the participants and serving as an advertisement for the sponsor for either a platform or content. participants will develop a working prototype or improving their coding abilities; sponsors, including libraries, can benefit from rapid prototyping and idea generation using either their platforms or content. while usable apps or new ideas are a welcome outcome, even if the applications are not used, the events still feed into the larger goal of marketing libraries and their data, building relationships with local communities, or drawing attention to social good. there are benefits to libraries in either hosting or collaborating on the events. in both areas, those of library as space and library as source, hackathons help realign user expectations of libraries. if libraries choose to become involved with hackathons or other coding or data contests, the library should be deliberate in its goals and intended outcomes as those will help shape both the event and its planning. libraries are naturally aligned with teaching and learning, are already offering co-curricular programming, and typically serve as physical and communication hubs for campus. libraries already prioritize outreach and engagement with constituents both on campuses and in the community. therefore, when programs align with library priorities of data literacy, data fluency, and information evaluation, it is a natural fit to propose involvement in hosting hackathons. many libraries are able to customize their spaces, services, and vendor interfaces, which is a benefit when thinking about having libraries as a theme for an event. other benefits exist for the hackathon event planners when partnering with a library. hackathon planners should consider reaching out to libraries as they already serve as a cross-disciplinary event spaces, host many other outreach events, and are often connected to other campus and community stakeholders and communication outlets. since students from all disciplines and colleges already use the library spaces on college campuses, they are an ideal location for fostering collaborations from different colleges and majors. public libraries function as community gathering spots as well. as libraries consider hosting events, several articles provide overarching tips for planning and hosting hackathons and other time-bound events.59 table 2 provides an overview of articles and the areas of coverage for planning topics. information technology and libraries december 2021 hackathons and libraries |longmeier 11 table 2. selected articles for tips on planning

reusable, hackathons will be a way to highlight data availability, promote its use and reuse, and reach out to the community. the issues present when considering library collections as potential hackathon themes are that libraries will need to ensure the data are cleaned and contain sufficient metadata so that the data are ready to use. additionally, if there are programming language restrictions for ongoing maintenance by the library after the event, those should be specified when advertising the event. ultimately, the libraries will likely not control the intellectual property (ip) of the tool or visualization developed, but several libraries have specified the ultimate ip as part of the event details either as open source or co-owned.60 often the goal of the event is the promotion of specific materials or building awareness of a collection rather than any biproduct created during the event. however, it is important for the library to be clear about their intent when advertising to participants. the collections-as-data movement will continue to evolve and there will be a multitude of library resources that could be mined for use at hackathons or other similar events. while libraries provide an ideal location and have access to data that can be used for an event, they can also leverage their wealth of experts. library staff can serve as judges, mentors, and connectors to the wider campus or community. events could highlight specific expertise when hackathons focus on particular approaches (data visualization), processes (metadata management or documentation), or codesign of services (physical spaces). table 3 provides examples of hackathon events from a variety of library contexts. hackathons are a great way for libraries to serve as a connector to others on campus or in their communities. if libraries are not interested or able to host an event themselves, library staff can act as mentors or event judges. at smaller schools, library staff can partner with other campus units to plan a hackathon; similarly, smaller public libraries could work with community organizations to host events. at a smaller scale if staffing is a concern or full hackathons are unrealistic, a coding contest or datathon, both of which typically have a shorter duration, might be an option. edit-a-thons are even easier to host as they require only an introduction to the editing process, ample computer space (or laptop hook-ups), and a small food budget. some edit-a-thon events happen in a single afternoon. information technology and libraries

these events relates to timing. while most hackathons last 24–36 hours, some are run over the course of a oneor two-month period where coding happens information technology and libraries december 2021 hackathons and libraries |longmeier 13 remotely with a few scheduled check-ins with mentors before judging and presentations. this notion of a remote event may have more appeal for collections-as-data–themed events as experts are more likely to be available for keynotes or mentoring. if the process instead of the product is the focus of the event, then providing a flexible structure may be more appealing to participants. if a library has more limited resources or capacity, stretching the event out over a longer period would allow for sustained interactions. however, libraries should be aware that the longer the event period, the greater the attrition of the participants. an area for future research includes assessment of library participation in events. a couple of articles highlighted the value the libraries found in the events, but it is unclear whether the participants also gained value from the libraries.61 typically, post-event surveys have focused on the participant experience or the overall event space, rather than whether it affected participants’ view of the libraries, which would another area of interest for future research.62 conclusion in the realm of hackathons and libraries, originally hackathon themes were a way that vendors could highlight new content or improve interfaces. libraries followed this trend and used events to reach out to constituents, make connections with their communities, and highlight evolving library services. with the growth of flexible spaces, ample technology support and more relaxed food policies, libraries have become ideal event locations. as the collections-as-data movement evolves, there will be more opportunities to develop services related to these data and other library data which would lend themselves easily as themes for hackathons, edit-a-thons, or datathons. libraries thinking about hosting events will need to weigh the amount of time and resources they want to invest with the intended goals of hosting an event. planning is essential whether the library is the event host, a collaborator, or a sponsor of a hackathon. for those libraries that are unable to host a full hackathon, smaller events, such as a datathon or edit-a-thon, are possibilities to provide support without the same time and resource commitment. given the growing popularity of hackathons and other coding contests, they may be a catch-all for solving several library issues simultaneously: updating the library’s image as being more than book-centric, supporting the collections-as-data movement, and a new way of engaging community partners. acknowledgements thank you to jody condit fagan for providing valuable suggestions on a draft of this paper and to the two anonymous reviewers whose

physics piotr adam praczyk, javier nogueras-iso, and salvatore mele information technology and libraries | december 2013 25 abstract plots and figures play an important role in the process of understanding a scientific publication, providing overviews of large amounts of data or ideas that are difficult to intuitively present using only the text. state-of-the-art digital libraries, which serve as gateways to knowledge encoded in scholarly writings, do not yet take full advantage of the graphical content of documents. enabling machines to automatically unlock the meaning of scientific illustrations would allow immense improvements in the way scientists work and the way knowledge is processed. in this paper, we present a novel solution for the initial problem of processing graphical content, obtaining figures from scholarly publications stored in pdf. our method relies on vector properties of documents and, as such, does not introduce additional errors, unlike methods based on raster image processing. emphasis has been placed on correctly processing documents in high-energy physics. the described approach distinguishes different classes of objects appearing in pdf documents and uses spatial clustering techniques to group objects into larger logical entities. many heuristics allow the rejection of incorrect figure candidates and the extraction of different types of metadata. introduction notwithstanding the technological advances of large-scale digital libraries and novel technologies to package, store, and exchange scientific information, scientists’ communication pattern has changed little in the past few decades, if not the past few centuries. the key information of scientific articles is still packaged in a form of text and, for several scientific disciplines, in a form of figures. new semantic text-mining technologies are unlocking the information in scientific discourse, and there exist some remarkable examples of attempts to extract figures from scientific publications,1 but current attempts do not provide a sufficient level of generality to deal with figures from high energy physics (hep) and cannot be applied in a digital library like inspire, which is our main piotr adam praczyk (piotr.praczyk@gmail.com) is a phd student at universidad de zaragoza, spain, and research grant holder at the scientific information service of cern, geneva, switzerland. javier nogueras-iso (jnog@unizar.es) is associate professor, computer science and systems engineering department, universidad de zaragoza, spain. salvatore mele (salvatore.mele@cern.ch) is leader of the open access section at the scientific information service of cern, geneva, switzerland. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 26 point of interest. scholarly publications in hep tend to contain highly specific types of figures (as any type of graphical content illustrating the text and referenced from it). in particular, they contain a high volume of plots, which are line-art images illustrating a dependency of a certain quality on a parameter. the graphical content of scholarly publications allows much more efficient access to the most important results presented in a publication.2,3 the human brain perceives the graphical content much faster than reading an equivalent block of text. presenting figures with the publication summary when displaying search results would allow more accurate assessment of the article content and in turn lead to a better use of researchers’ time. enabling users to search for figures describing similar quantities or phenomena could become a very powerful tool for finding publications describing similar results. combined with additional metadata, it could provide knowledge about evolution of certain measurements or ideas over time. these and many more applications created an incentive to research possible ways to integrate figures in inspire. inspire is a digital library for hep,4 the application field of this work. it provides a large-scale digital library service (1 million records, fifty-thousand users), which is starting to explore new mechanisms of using figures in articles of the field to index, retrieve, and present information.5,6 as a first step, direct access to graphical content before accessing the text of a publication can be provided. second, a description of graphics (“blue-band plot,” “the yellow shape region”) could be used in addition to metadata or full-text queries to retrieve a piece of information. finally, articles could be aggregated into clusters containing the same or similar plots in a possible alternative automated answer to a standing issue in information management. the indispensable step to realize this vision is an automated, resilient, and high-efficiency extraction of figures from scientific publications. in this paper, we present an approach that we have developed to address this challenge. the focus has been put on developing a general method allowing the extraction of data from documents stored in portable document format (pdf). the results of the algorithm consist of metadata, raster images of a figure, but also vector graphics, which allows easier further processing. the pdf format has been chosen as the input of the algorithm because it is a de facto standard in scientific communication. in the case of hep, mathematics, and other exact sciences, the majority of publications are prepared using the latex document formatting system and later compiled into a pdf file. the electronic versions of publications from outstanding scientific journals are also provided in pdf. the internal structure of pdf files does not always reveal the location of graphics. in some cases, images are included as external entities and easily distinguishable from the rest of a document’s content, but other times they are mixed with the rest of the content. therefore, to miss any figures, the low-level structure of a pdf had to be analyzed. the work described in this paper focuses on the area of hep. however, with minor variations, the described methods could be applicable to a different area of knowledge. information technology and libraries | december 2013 27 related work over years of development of digital libraries and document processing, researchers came up with several methods of automatically extracting and processing graphics appearing in pdf documents. based on properties of the processed content, these methods can be divided into two groups. the attempts of the first category deal with pdf documents in general, not making any assumptions about the content of encoded graphics or document type. the methods from the second group are more specific to figures from scientific publications. our approach belongs to the second group. tools include command line programs like pdf-images (http://sourceforge.net/projects/pdfimages/) or web-based applications like pdf to word (http://www.pdftoword.com/). these solutions are useful for general documents, but all suffer from the same difficulties when processing scientific publications: graphics that are recognized by such tools have to be marked as graphics inside pdf documents. this is the case with raster graphics and some other internally stored objects. in the case of scholarly documents, most graphics are constructed internally using pdf primitives and thus cannot be correctly processed by tools from the first group. moreover, general tools do not have the necessary knowledge to produce metadata describing the extracted content. with respect to specific tools for scientific publications it must be noted first that important scientific publishers like springer or elsevier have created services to allow access to figures present in scientific publications: the improvement of the sciverse science direct site (http://www.sciencedirect.com) for searching images in the case of elsevier7 and the springerimages service (http://www.springerimages.com/) in the case of springer.8 these services allow searches triggered from a text box, where the user can introduce a description of the required content. it is also possible to browse images by categories such as types of graphics (image, table, line art, video, etc.). the search engines are limited to searches based on figure captions. in this sense, there is little difference between the image search and text search implemented in a typical digital library. most of existing works aiming at the retrieval and analysis of figures use the rasterized graphical representation of source documents as its basis. browuer et al. and kataria et al. describe a method of detecting plots by means of wavelet analysis.9,10 they focus on the extraction of data points from identified figures. in particular, they address the challenge of correctly identifying overlapping points of data in plots. this problem would not manifest itself often in the case of vector graphics, which is the scenario proposed in our extraction method. vector graphics preserve much more information about the documents content than simple values of pixel colours. in particular, vector graphics describe overlapping objects separately. raster methods are also much more prone to additional errors being introduced during the recognition/extraction phase. the methods described in this paper could be used with kataria’s method for documents resulting from a digitization process.11 http://sourceforge.net/projects/pdf-images/) http://sourceforge.net/projects/pdf-images/) http://www.pdftoword.com/). http://www.sciencedirect.com/ http://www.springerimages.com/ automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 28 liu et al. present a page box-cutting algorithm for the extraction of tables from pdf documents.12 their approach is not directly applicable, but their ideas of geometrical clustering of pdf primitives are similar to the ones proposed in our work. however, our experiments with their implementation and hep publications have shown that the heuristics used in their work cannot be directly applied to hep, showing the need for an adapted approach, even in the case of tables. a different category of work, not directly related to graphics extraction but useful when designing algorithms, has been devoted to the analysis of graph use in scientific publications. the results presented by cleveland describe a more general case than hep publications.13 even if the data presented in the work came from scientific publications before 1984, included observations—for example, typical sizes of graphs—were useful with respect to general properties of figures and were taken into account when adjusting parameters of the presented algorithm. finally, there exist attempts to extract layout information from pdf documents. the knowledge of page layout is useful to distinguish independent parts of the content. the approach of layout and content extraction presented by chao and fan is the closest to the one we propose in this paper.14 the difference lies in the fact that we are focusing on the extraction of plots and figures from scientific documents, which usually follow stricter conventions. therefore we can make more assumptions about their content and extract more precise data. for instance, our method emphasizes the role of detected captions and permits them to modify the way in which graphics are treated. we also extract portions of information that are difficult to be extracted using more general methods, such as captions of figures. method pdf files have a complex internal structure allowing them to embed various external objects and to include various types of metadata. however, the central part of every pdf file consists of a visual description of the subsequent pages. the imaging model of pdf uses a language based on a subset of the postscript language. postscript is a complete programming language containing instructions (also called operators) allowing the rendering of text and images on a virtual canvas. the canvas can correspond to a computer screen or to another, possibly virtual, device used to visualize the file. the subset of postscript, which was used to describe content of pdfs, had been stripped from all the flow control operations (like loops and conditional executions), which makes it much simpler to interpret than the original postscript. additionally, the state of the renderer is not preserved between subsequent pages, making their interpretation independent. to avoid many technical details, which are irrelevant in this context, we will consider a pdf document as a sequence of operators (also called the content stream). every operator can trigger a modification of the graphical state of the pdf interpreter, which might be drawing a graphical primitive, rendering an external attached object, or modifying a position of the graphical pointer15 or a transformation matrix.16 the outcome of an atomic operation encoded in the content stream depends not only on parameters of the operation, but also on the way previous operators modified information technology and libraries | december 2013 29 the state of the interpreter. such a design makes a pdf file easy to render but not necessarily easy to analyze. figure 1 provides an overview of the proposed extraction method. at the very first stage, the document is pre-processed and operators are extracted (see “pre-processing of operators” below). later, graphical17 and textual18 operators are clustered using different criteria (see “inclusion of text parts” and “detection and matching of captions” below), and the first round of heuristics rejects regions that cannot be considered figures. in the next phase, the clusters of graphical operators are merged with text operators representing fragments of text to be included inside a figure (see “inclusion of text parts” below). the second round of heuristics detects clusters that are unlikely to be figures. text areas detected by the means of clustering text operations are searched for possible figure captions (see “detection and matching of captions” below). captions are matched with corresponding figure candidates, and geometrical properties of captions are used to refine the detected graphics. the last step generates data in a format convenient for further processing (see “generation of the output” below). figure 1. overview of the figure extraction method. additionally, it must be noted that another important pre-processing step of the method consists of the layout detection. an algorithm for segmenting pages into layout elements called page divisions is presented later in the paper. this considerably improves the accuracy of the extraction method because elements from different page divisions can no longer be considered to belong to the same cluster (and subsequently figure). this allows the method to be applied separately to different columns of a document page. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 30 pre-processing of operators the proposed algorithm considers only certain properties of a pdf operator rather than trying to completely understand its effect. considered properties consist of the operators’ type, the region of the page where the operator produces output and, in the case of textual operations, the string representation of the result. for simplicity, we suppress the notion of coordinate system transformation, inherent for the pdf rendering, and describe all operators in a single coordinate system of a virtual 2-dimensional canvas where operations take effect. transformation operators19 are assigned an empty operation region as they do not modify the result directly but affect subsequent operations. in our implementation, an existing pdf rendering library has been used to determine boundaries of operators. rather than trying to understand all possible types of operators, we check the area of the canvas that has been affected by an operation. if the area is empty, we consider the operation to be a transformation. if there exists a non-empty area that has been changed, we check if the operator belongs to a maintained list of textual operators. this list is created based on the pdf specification. if so, the operators argument list is scanned searching for a string and the operation is considered to be textual. an operation that is neither a transformation nor a textual operation is considered to be graphical. it might happen that text is generated using a graphical operator. however, such a situation is unusual. in the case of operators triggering the rendering of other operators, which is the case when rendering text using type-3 fonts, we consider only the top-level operation. in most cases, separate operations are not equivalent to logical entities considered by a human reader (such as a paragraph, a figure, or a heading). graphical operators are usually responsible for displaying lines or curve segments while humans think in terms of illustrations, data lines, etc. similarly, in the case of text, operators do not have to represent complete or separate words or paragraphs. they usually render parts of words and sometimes parts of more than one word. the only assumption we make about the relation between operators and logical entities is that a single operator does not trigger rendering of elements from different detected entities (figures, captions). this is usually true because logical entities tend to be separated by a modification of the context—there is a distance between text paragraphs or an empty space between curves. clustering of graphical operators the clustering algorithm the representation of a document as a stream of rectangles allows the calculation of more abstract elements of the document. in our model, every logical entity of the document is equivalent to a set of operators. the set of all operators of the document is divided into disjoint subsets in the process called clustering. operators are decided to belong to the same cluster based on the position of their boundaries. the criteria for the clustering are based on a simple but important observation: information technology and libraries | december 2013 31 operations forming a logical entity have boundaries lying close to each other. groups of operations forming different entities are separated by empty spaces. algorithm 1. the clustering algorithm. the clustering of textual operations yields text paragraphs and smaller objects like section headings. however, in the case of graphical operations, we can obtain consistent parts of images, but usually not complete figures yet. outcomes of the clustering are utilized during the process of figures detection. algorithm 1 shows the pseudo-code of the clustering algorithm. the input of the algorithm consists of a set of pre-processed operators annotated with their affected area. the output is a division of the input set into disjoint clusters. every cluster is assigned a boundary equal to the smallest rectangle containing boundaries of all included operations. in the first stage of the algorithm (lines 6–20), we organize all input operations in a data structure of forest of trees. every tree describes a separate cluster of operations. the second stage (lines 21– 29) converts the results (clusters) into a more suitable format. 1: input: operationset input_operations {set of operators

physics | praczyk, nogueras-iso, and mele 32 the clustering of operations is based on the relation of their rectangles being close to each other. definition 1 formalizes the notion of being close, making it useful for the algorithm. definition 1: two rectangles are considered to be located close to each other if they are intersecting after expanding their boundaries in every direction by a margin. the value by which rectangles should be extended is a parameter of the algorithm and might be different in various situations. to detect if rectangles are close to each other, we needed a data structure allowing the storage a set of rectangles. this data structure was required to allow retrieving all stored rectangles that intersect a given one. we have constructed the necessary structure using an important observation about the operation result areas. in our model all bounding rectangles have their edges parallel to the edges of the reference canvas on which the output of the operators is rendered. this allowed us to reduce our problem from the case of 2-dimensional rectangles to the case of 1-dimensional intervals. we can assume that edges of the rectangular canvas define the coordinates system. it is easy to prove that two rectangles of edges parallel to the axis of the coordinates system intersect only if both their projections in the directions of axis intersect. the projection of a rectangle into an axis is always an interval. the observation made above has allowed us to build the required 2-dimensional data structure by remembering two 1-dimensional data structures that recall a number of intervals and for a given interval return the set of intersecting ones. such a 1-dimensional data structure has been provided by interval-trees.20 every interval inside the tree has an arbitrary object assigned to it, which in this case is a representation of the pdf operator. this object can be treated as an identifier of the interval. the data structure also implements a dictionary interface, mapping objects to actual intervals. at the beginning, the algorithm initializes two empty interval trees representing projections on the x and y axes, respectively. those trees store values about projections of the biggest so-far calculated areas rather than about particular operators. each cluster is represented by the most recently discovered operation belonging to it. during the algorithm execution, each operator from the input set is considered only once. the order of processing is not important. the processing of a single operator proceeds as follows (the interior of the outermost “for all” loop of the algorithm). 1. the boundary of the operation is extended by the width of margins. the spatial data structure described earlier is utilized to retrieve boundaries of all already detected clusters (lines 9–10) 2. the forest of trees representing clusters is updated. the currently processed operation is added without a parent. roots of all trees representing intersecting clusters (retrieved in previous step) are attached as children of the new operation. information technology and libraries | december 2013 33 3. the boundary of the processed operation is extended to become the smallest rectangle containing all boundaries of intersecting clusters and the original boundary. finally, all intersecting clusters are removed from the spatial data structure. 4. lines 9–17 of the algorithm are repeated as long as there exist areas intersecting the current boundary. in some special cases, more than one iteration may be necessary. 5. finally, the calculated boundary is inserted into the spatial data structure as a boundary of a new cluster. the currently processed operation is designed to represent the cluster and so is remembered as a representation of the cluster. after processing all available operations, the post–processing phase begins. all the trees are transformed into lists. the resulting data structure is a dictionary having boundaries of detected clusters as keys and lists of belonging operations as values. this is achieved in lines 21–29. during the process of retrieving the cluster to which a given operation belongs, we use a technique called path compression, known from the union-find data structure.21 filtering of clusters graphical areas detected by a simple clustering usually do not directly correspond to figures. the main reason for this is that figures may contain not only graphics, but also portions of text. moreover, not all graphics present in the document must be part of a figure. for instance, common graphical elements not belonging to a figure include logos of institutions and text separators like lines and boxes; various parts of mathematical formulas usually include graphical operations; and in the case of slides from presentations, the graphical layout should not be considered part of a figure. the above shows that the clustering algorithm described earlier is not sufficient for the purpose of figures detection and it yields a results set wider than expected. in order to take into account the aforementioned characteristics, pre-calculated graphical areas are subject to further refinement. this part of the processing is highly domain-dependent as it is based on properties of scientific publications in a particular domain, in this case publications of hep. in the course of the refinement process, previously computed clusters can be completely discarded, extended with new elements, or some of their parts might be removed. in this subsection we discuss the heuristics applied for rejecting and splitting clusters of graphical operators. there are two main reasons for rejecting a cluster. the first of them is a size being too small compared to a page size. the second is the figure candidate having its aspect ratio outside a desired interval of values. the first heuristic is designed to remove small graphical elements appearing for example inside mathematical formulas, but also small logos and other decorations. the second one discards text separators and different parts of mathematical equations, such as a line-separating numerator from a denominator inside a fraction. the thresholds used for filtering are provided as automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 34 configurable properties of the algorithm and their values are assigned experimentally in a way maximising the accuracy of figures detection. additionally, the analysis of the order of operations forming the content stream of a pdf document may help to split clusters that were incorrectly joined by algorithm 1. parts of the stream corresponding to logical parts of the document usually form a consistent subsequence. this observation allows the construction of a method of splitting elements incorrectly clustered together. we can assign content streams not only to entire pdf documents or pages, but also to every cluster of operations. the clustering algorithm presented in algorithm 1 returns a set of areas with a list of operations assigned to each of them. the content stream of a cluster consists of all operations from such a set ordered in the same manner as in the original content stream of the pdf document. the usage of the original content stream allows us to define a distance in the content stream as follows: definition 2. if o 1 and o 2 are two operations appearing in the content stream of the pdf document, by the distance between these operations we understand the number of textual and graphical operations appearing after the first of them and before the second of them. to detect situations when a figure candidate contains unnecessary parts, the content stream of a figure candidate is read from the first to the last operation. for every two subsequent operations, the distance between them in the sense of the original content stream is calculated. if the value is larger than a given threshold, the content stream is split into two parts, which become separate figure candidates. for both candidates, a new boundary is calculated. this heuristic is especially important in the case of less formal publications such as slides from presentations at conferences. presentation slides tend to have a certain number of graphics appearing on every page and not carrying any meaning. simple geometrical clustering would connect elements of page style with the rest of the document content. measuring the distance in the content stream and defining a threshold on the distance facilitates the distinction between the layout and the rest of the page. this technique also might be useful to automatically extract the template used for a presentation, although this transcends the scope of this publication. clustering of textual operators the same algorithm that clusters graphical elements can cluster parts of text. detecting larger logically consistent parts of text is important because they should be treated as single entities during subsequent processing. this comprises, for example, inclusion inside a figure candidate (e.g., captions of axes, parts of a legend) and classification of a text paragraph as a figure caption. inclusion of text parts the next step in figures extraction involves the inclusion of lost text parts inside figure candidates. information technology and libraries | december 2013 35 at the stage of operations clustering, only the operations of the same type (graphical or textual) were considered. the results of those initial steps become the input to the clustering algorithm that will detect relations between previously detected entities. by doing this, we move one level farther in the process of abstracting from operations. we start from basic meaningless operations. later we detect parts of graphics and text, and finally we are able to see the relations between both. not all clusters detected at this stage are interesting because some might consist uniquely of text areas. only those results that include at least one graphical cluster may be subsequently considered figure candidates. another round of heuristics marks unnecessary intermediate results as deleted. applied methods are very similar to those described in “filtering of clusters” (above), only thresholds deciding on the rejections must change because we operate on geometrically much larger entities. also the way of application is different—candidates rejected at this stage can be later restored to the status of a figure. instead of permanently removing, heuristics of this stage only mark figure candidates as rejected. this happens in the case of the candidates having incorrect aspect ratio, incorrect sizes or consisting only of horizontal lines (which is usually the case with mathematical formulas but also tables). in addition to using the aforementioned heuristics, having clusters consisting of a mixture of textual and graphical operations allows the application of new heuristics. during the next phase, we analyze the type of operations rather than their relative location. in some cases, steps described earlier might detect objects that should not be considered a figure, such as text surrounded by a frame. this situation can be recognized by the calculation of a ratio between the number of graphical and textual operations in the content stream of a figure candidate. in our approach we have defined a threshold that indicates which figure candidates should be rejected because they contain too few graphics. this allows the removal of, for instance, blocks of text decorated with graphics for aesthetic reasons. the ratio between numbers of graphical and textual operations is smaller for tables than for figures, so extending the heuristic with an additional threshold could improve the table–figure distinction. another heuristic analyzes ratio between the total area of graphical operations and the area of the entire figure candidate. subsequently, we mark as deleted the figure candidates containing horizontal lines as the only graphical operations. these candidates describe tables or mathematical formulas that have survived previous steps of the algorithm. tables can be reverted to the status of figure candidates in later stages of processing. figure candidates that survive all the phases of filtering are finally considered to be figures. figure 2 shows a fragment of a publication page with indicated text areas and final figure candidates detected by the algorithm. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 36 figure 2. a fragment of the pdf page with boxes around every detected text area and each figure candidate. dashed rectangles indicate figure candidates. solid rectangles indicate text areas. detection and matching of captions the input of the part of the algorithm responsible for detecting figure captions consists of previously determined figures and all text clusters. the observation of scientific publications shows that, typically, captions of figures start with a figure identifier (for instance see the grammar for figure captions proposed by bathia, lahiri, and mitra.22 the identifier usually starts with a word describing a figure type and is followed by a number or some other unique identifier. in more complex documents, the figure number might have a hierarchical structure reflecting, for example, the chapter number. the set of possible figure types is very limited. in the case of hep publications, the most usual combinations include words “figure”, “plot,” and different variations of their spelling and abbreviating. information technology and libraries | december 2013 37 during the first step of the caption detection, all text clusters from the publication page are tested for the possibility of being a caption. this consists of matching the beginning of the text contained in a textual cluster with a regular expression determining what is a figure caption. the role of the regular expression is to elect strings starting with one of the predefined words, followed by an identifier or beginning of a sentence. the identifier is subsequently extracted and included in the metadata of a caption. the caption detection has to be designed to reject paragraphs of the type “figure 1 presents results of (. . .)”. to achieve this, we reject the possibility of having any lowercase text after the figure identifier. having the set of all the captions, we start searching for corresponding figures. all previous steps of the algorithm take into account the division of a page into text columns (see “detection of the page layout” below). when matching captions with figure candidates, we do not take into account the page layout. matching between figure candidates and captions happens at every document page separately. we consider every detected caption once, starting with those located at the top of the page and moving down toward the end. for every caption we search figure candidates lying nearby. first we search above the caption and, in the case of failure, we move below the caption. we take into account all figure candidates, including those rejected by heuristics. in the case of finding multiple figure candidates corresponding to a caption, we merge them into a single figure, treating previous candidates as subfigures of a larger figure. we also include small portions of text and graphics previously rejected from figure candidates that lie between figure and caption and between different parts of a figure. these parts of text usually contain identifiers of the subfigures. the amount of unclustered content that can be included in a figure is a parameter of the extraction algorithm and is expressed as a percentage of the height of the document page. it might happen that captions are located in a completely different location, but this case is rare and tends to appear in older publications. the distance from the figure is calculated based on the page geometry. the captions should not be too distant from the figure. generation of the output the choice of the format in which data should be saved at the output of the extraction process should take into account further requirements. the most obvious use case of displaying figures to end users in response to text-based search queries does not yield very sophisticated constraints. a simple raster graphic annotated with captions and possibly some extracted portions of metadata would be sufficient. unfortunately, the process of generating raster representations of figures might lose many important pieces of information that could be used in the future for an automatic analysis. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 38 to store as much data as possible, apart from storing the extracted figures in a raster format (e.g., png), we also decided to preserve their original vector character. vector graphics formats, similarly to pdf documents, contain information about graphical primitives. primitives can be organized in larger logical entities. sometimes rendering of different primitives leads to a modification of the same pixel of resulting image. such a situation might happen, for example, when circles are used to draw data points lying nearby on the same plot. to avoid such issues, we convert figures into scalable vector graphics (svg) format.23 on the implementation level, the extraction of vector representation of a figure proceeds in a manner similar to regular rendering of a pdf document. the interpreter preserves the same elements of the state and allows their modification by transformation operations. a virtual canvas is created for every detected figure. the content stream of the document is processed and all the transformation operations are executed modifying the interpreter’s state. the textual and graphical operators are also interpreted, but they affect only the appropriate canvas of the figure to which the operation belongs. if a particular operation does not belong to any figure, no canvas is affected. the behaviour of graphical canvases used during the svg generation is different from the case of raster rendering. instead of creating graphical output, every operation is transformed into a corresponding primitive and saved within an svg file. pdf was designed in such a manner that the number of external dependencies of a file is minimized. this design decision led to the inclusion of the majority of fonts in the document itself. it would be possible to embed font glyphs in the svg file and use them to render strings. however, for the sake of simplicity, we decided to omit font definitions in the svg output. a text representation is extracted from every text operation, and the operation is replaced by a svg text primitive with a standard font value. this simplification affects what the output looks like, but the amount of formatting information that is lost is minimal. moreover, this does not pose a problem because vector representations are intended to be used during automatic analysis of figures rather than for displaying purposes. a possible extension of the presented method could involve embedding complete information about used glyphs. finally, the generation of the output is completed with some metadata elements. an exhaustive categorization of the metadata that can be compiled for figures could be the customization of the one proposed by liu et al. for table metadata.24 in the case of figures, the following categories could be distinguished: (1) environment/geography metadata (information of the document where the figure is located); (2) affiliated metadata (e.g., captions, references, or footnotes); (3) layout metadata (information about the original visualization of the figure); (4) content data; and (5) figure type metadata. for the moment, we compile only environment/geography metadata and affiliated metadata. the geography/environment metadata consists of the document title, the document authors, the document date (creation and publication), and the exact location of a figure inside a publication information technology and libraries | december 2013 39 (page and boundary). most of these elements are provided by simply referencing the original publication in the inspire repository. the affiliated metadata consists of the text caption and the exact location of the caption in the publication (page and boundary). in the future, metadata from other categories will be annotated for each figure. detection of the page layout figure 3. sample page layouts that might appear in a scientific publication. the black color indicates areas where content is present. in this section we discuss how to detect the page layout, an issue which has been omitted in the main description of the extraction algorithm, but which is essential for an efficient detection of figures. figure 3 depicts several possibilities of organising content on the page. as mentioned in previous sections, the method of clustering operations based on their geometrical position may fail in the case of documents having a complex page layout. the content appearing in different columns should never be considered belonging to the same figure. this cannot be assured without enforcing additional constrains during the clustering phase. to address this difficulty, we enhanced the figure extractor with a pre-processing phase of detecting the page layout. being able to identify how the document page is divided into columns enables us to execute the clustering within every column separately. it is intuitively obvious, what can be understood as a page layout, although to provide a method of calculating such, we need a more formal definition, which we provide below. by the layout of a page, we understand a particular division of a page into areas called columns. each area is a sum of disjoint rectangles. the division of a page into areas must satisfy a set of conditions summarized in definition 3. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 40 definition 3: let p be a rectangle representing the page. the set d containing subareas of a page is called a page division if and only if � 𝑄 = 𝑃 𝑄∈𝐷 ∀𝑥,𝑦∈𝐷𝑥 ∩ 𝑦 = ∅ ∀𝑄∈𝐷𝑄 ≠ ∅ ∀𝑄∈𝐷∃𝑅=�𝑥:𝑥 𝑖𝑠 𝑎 𝑟𝑒𝑐𝑡𝑎𝑛𝑔𝑙𝑒,∀𝑦∈r\{x} 𝑦∩x=∅ �𝑄 = � 𝑥𝑥∈𝑅 every element of a division is called a page area. to be considered a page layout, borders of areas from the division must not intersect the content of the page. definition 3 does not guarantee that the layout is unique. a single page might be assigned different divisions satisfying the definition. additionally, not all valid page layouts are interesting from the point of view of figures detection. the segmentation algorithm calculates one of such divisions, imposing additional constraints on the detected areas. the layout-calculation procedure utilizes the notion of separators, introduced by definition 4. definition 4: a vertical (or horizontal) line inside a page or on its borders is called a separator if its horizontal (vertical) distance from the page content is larger than a given constant value. the algorithm consists of two stages. first, the vertical separators of a sufficient length are detected and used to divide the page into disjoint rectangular areas. each area is delimited by two vertical lines, each of which forms a consistent interval inside of one of the detected vertical separators. at this stage, horizontal separators are completely ignored. figure 4 shows a fragment of a publication page processed by the first stage of the layout-detection. the upper horizontal edge of one of the areas lies too close too close to two text lines. with the constant of the definition 4 chosen to be sufficiently large, this edge would not be a horizontal separator and thus the generated division of the page would require additional processing to become a valid page layout. the second stage of the algorithm transforms the previously detected rectangles into a valid page layout by splitting rectangles into smaller parts and by joining appropriate rectangles to form a single area. information technology and libraries | december 2013 41 figure 4. example of intermediate layout-detection results requiring the refinement. algorithm 2 shows the pseudo-code of the detection of vertical separators. the input of the algorithm consists of the image of the publication page. the output is a list of vertical separators aggregated by their x-coordinates. every element of this list consists of two elements: an integer indicating the x-coordinate and the list of y-coordinates describing the separators. the first element of this list indicates the y-coordinate of the beginning of the first separator. the second element is the y-coordinate of the end of the same separator. the third and fourth elements describe the second separator and the same mechanism is used for the remaining separators (if they exist). the algorithm proceeds according to the sweeping principle known from the computational geometry.25 the algorithm reads the publication page starting from the left. for every xcoordinate value, a set of corresponding vertical separators is detected (lines 9–18). vertical separators are searched as consistent sequences of blank points. a point is considered blank if all the points in its horizontal surrounding of the radius defined by the constant from definition 5 are of the background colour. not all blank vertical lines can be considered separators. short, empty spaces usually delimit lines of text or different small units of the content. in line 11 we test detected vertical separators for being long enough. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 42 if a separator has been detected in a particular column of a publication page, the adjacent columns also tend to contain similar separators. lines 19–31 of the algorithm are responsible for electing the longest candidate among the adjacent columns of the page. the maximization is performed across a set of adjacent columns for which at least one separator exists. algorithm 2. detecting vertical separators. the detected separators are used to create the preliminary division of the page, similar to the one from the example of figure 4. as with the previous step, separators are considered one by one in the order of increasing x coordinate. at every moment of the execution, the algorithm maintains a division of the page into rectangles. this division corresponds only to the already detected vertical separators. updating the previously considered division is facilitated by processing separators in a particular well-defined order. 1: input: the page image 2: output: vertical separators of the input page 3: list<pair<int, list<int>> separators ← ∅ 4: int max_weight ← 0; 5: boolean maximizing ← false 6: for all x ∈ {minx … maxx} do 7: emptyb ← 0, current_eval ← 0 8: empty_areas ← list() 9: for all

and libraries | december 2013 43 before presenting the final outcome, the algorithm must refine the previously calculated division. this happens in the second phase of the execution. all the horizontal borders of the division are then moved along adjacent vertical separators until they become horizontal separators in the sense of definition 4. typically, moving the horizontal borders result in dividing already existing rectangles into smaller ones. if such a situation happens, both newly created parts are assigned to different page layout areas. sometimes when moving separators is not possible, different areas are combined together, forming a larger one. tuning and testing the extraction algorithm described here has been implemented in java and tested on a random set of scientific articles coming from the inspire repository. the testing procedure has been used to evaluate the quality of the method, but also allowed to tweak the parameters of the algorithm to maximize the outcomes. preparation of the testing set to prepare the testing set, we randomly selected 207 documents stored in inspire. in total, these documents consisted of 37,28 pages which contained 1,697 figures altogether. the records have been selected according to a uniform probability distribution across the entire record space. this way, we have created a collection that is representative for the entire inspire including historical entries. currently, inspire consists of: 1,140 records describing publications written before 1950; 4,695 between 1950 and 1960; 32,379 between 1960 and 1970; 108,525 between 1970 and 1980; 167,240 between 1980 and 1990; 251,133 between 1990 and 2000; and 333,864 in the first decade of the twenty-first century. in total, up to july 2012, inspire manages 952,026 records. it can be seen that the rate of growth has increased with time and most of inspire documents come from the last decade. the results on such a testing set should accurately estimate the efficiency of extraction for existing documents but not necessarily for new documents, being ingested into inspire. this is because inspire contains entries describing old articles which were created using obsolete technologies or scanned and encoded in pdf. the extraction algorithm is optimized for born-digital objects. to test the hypothesis that the extractors provides better results for newer papers, the testing set has been split into several subsets. the first set consists of publications published before 1980. the rest of the testing set has been split into subsets corresponding to decades of publication. to simplify the counting of correct figure detections and to provide a more reliable execution and measurement environment, every testing document has been split into many of pdf documents consisting of a single page. subsequently, every single page document has been manually annotated with the number of figures appearing inside. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 44 execution of the tests the efficient execution of the testing was possible thanks to a special script executing the plots extractor on every single page separately and then computing the total number of successes and failures. the script allows the execution of tests in a distributed heterogeneous environment and allows dynamic connection and disconnection of computing nodes. in the case of a software failure, the extraction request is resubmitted to a different computation node, allowing the avoidance problems related to a worker node configuration rather than to the algorithm implementation itself. during the preparation of the testing set, we manually annotated all the expected extraction results. subsequently, the script compared these metadata with the output of the extractor. using aggregated numbers from all extracted pages allowed us to calculate efficiency measures of the extraction algorithm. as quality measures, we used recall and precision.26 their definitions are included in the following equations: at every place where we needed a single comparable quality measure rather than two semiindependent numbers, we have used a harmonic average of the precision and the recall.27 table 1 summarizes the results obtained during the test execution for every subset of our testing set. figure 5 shows the dependency of recall and precision on the time of publication. the extractor parameters used in this test execution were chosen based on intuition and small number of manually triggered trials. in the next section we describe an automatic tuning procedure we have used to find the most optimal algorithm arguments. testsettheinpresentfigures

expected, the efficiency increases with the increasing time of publication. a total recall and precision for all samples since 1990, which constitutes a majority of the inspire corpus, were both 88 percent. precision and recall based on the correctly detected figures do not give a full image of the algorithm efficiency because the extraction has been executed on a number of pages not containing any figures. the correctly extracted pages not having any figures do not appear in the recall and precision statistics because in their case the expected and detected number of figures are both equal to 0. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 46 besides recall and precision, figure 5 depicts also the fraction of pages that have been extracted correctly. taking into account the samples since 1990, 3,271 pages out of 3,507 have been detected completely correctly, which makes 93 percent success rate counted by number of pages. as it can be seen, this measure is higher than both the precision and the recall. the analysis of the extractor results in the case of failure shows that in many cases, even if results are not completely correct, they are not far from the expectation. there are different reasons of the algorithm failing. some of them may result from non-optimal choice of algorithm parameters, others from document layout being too far from the assumed one. in some rare cases, even manual inspection of the document does not allow an obvious identification of figures. the automatic tuning of parameters in previous section we have shown the results obtained by executing the extraction algorithm on a sample set. during this execution we were using extractor arguments which seemed to be the most correct based on our observation but also on other research (typical sizes of figures, margin sizes, etc.).28 this way of algorithm configuration was useful during the development, but is not likely to yield the best possible results. to find better parameters, we have implemented a method of automatic tuning. metrics described in the previous section provided a good method of measuring the efficiency of the algorithm running based on given parameters. the choice of optimal parameters can be relative to the choice of documents on which the extraction is to be performed. the way in which the testing set has been selected, allowed us to use it as representative for the hep publications. to tune the algorithm, we have used a described subset of testing set from the previous step as a reference. the subset consisted of all entries created after 1990. this allowed us to minimize the presence of scanned documents which, by design, cannot be correctly processed by our method. the adjustment of parameters has been performed by a dedicated script which has executed the extraction using various parameter values and has read results. the script has been configured with a list of tuneable parameters together with their type and allowed values range. additionally, the script had the knowledge of the believed best value, which was the one used in previous testing. to decrease the complexity of training, we have made several assumptions about the parameters. these assumptions are only an approximation of real nature of parameters, but the practice has shown that they are good enough to permit the optimization: • we assume that the precision and recall are continuous with respect to the parameters. this allows us to assume that efficiency of the algorithm for parameter values close to a given one will be close. the optimization has proceeded by sampling the parametric space in a number of points and executing tests using the selected points as parameter values. information technology and libraries | december 2013 47 having n parameters to optimize and dividing the space of every parameter into m regions leads to the execution of mn tests. execution of every test is a timely operation due to the size of the training set. • we assume that parameters are independent from each other. this means that we can divide the problem of finding an optimal solution in the n-dimensional space of n configuration arguments into finding n solutions in 1-dimensional subspaces. such an assumption seems to be intuitive and considerably reduces the number of necessary tests from o(mn) to o(m⋅n), where m is the number of samples taken from a single dimension. in our tests, the parametric space has been divided into 10 equal intervals in every direction. in addition to checking the extraction quality in those points, we have executed one test for the so-far best argument. in order to increase the level of fine-tuning of the algorithm, each test has been reexecuted in the region, where chances of finding a good solution were considered the highest. this consisted of a region centred around the highest result and having a radius of 10 percent of the parameter space. figure 6 and figure 7 show the dependency of the recall and the precision on an algorithm parameter. the parameter depicted in figure 6 indicates what minimal aspect ratio the figure candidate must have in order to be considered a correct figure. it can be seen that tuning this heuristic increases the efficiency of the extraction. moreover, the dependency of recall and precision on the parameter is monotonic which is the most compatible with the chosen optimization method. the parameter of figure 7 specifies which fraction of the area of the entire figure candidate has to be occupied by graphical operations. this parameter has a lower influence on the extraction efficiency. such a situation can happen when more than one heuristic influences the same aspect of the. this is contradictory with the assumption of parameter independence, but we have decided to use the present model for the simplicity. figure 6. effect of the minimal aspect ratio on precision and recall. automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 48 figure 7. effect on the precision and recall of the area fraction occupied by graphical operations. after executing the optimization algorithm, we have managed to achieve a recall of 94.11 percent and a precision of 96.6 percent, which is a considerable improvement compared to previous results of 88 percent. conclusions and future work this work has presented a method for extracting figures from scientific publications in a machinereadable format, which is the main step toward the development of services enabling access and search of images stored in scientific digital libraries. in recent years, figures have been gaining increasing attention in the digital libraries community. however, little has been done to decipher the semantics of these graphical representations and to bridge the semantic gap between content, which can be understood by machines and this which is managed by digital libraries. extracting figures and storing them in uniform and machine-readable format constitutes the first step towards the extraction and the description of the internal semantics of figures. storing semantically described and indexed figures would open completely new possibilities of accessing the data and discovering connections between different types of publishing artefacts and different resources describing related knowledge.29 our method of detecting fragments of pdf documents that correspond to figures is based on a series of observations of the character of publications. however, tests have shown that additional work is needed to improve the correctness of the detection. also, the performance should be reevaluated after we have a large set of correctly annotated figures, confirmed by users of our system. the heuristics used by the algorithm are based on a number of numeric parameters that we have tried to optimize using automatic techniques. the tuning procedure has made several arbitrary assumptions on the nature of the dependency between parameters and extraction results. a future approach to the parameter optimization, requiring much more processing, could information technology and libraries | december 2013 49 involve the execution of a genetic algorithm that would treat the parameters as gene samples.30 this could potentially allow a discovery of a better parameter set because a smaller set of assumptions would be imposed on the parameters. a vector of algorithm parameters could play the role of a gene and random mutations could be introduced to previously considered and subsequently crossed genes. the evaluation and selection of surviving genes could be performed by the usage of the metrics described previously. another approach to improving the quality of the tuning could involve extending the present algorithm by a discovery of mutually dependent parameters and usage of special techniques (relaxing the assumptions) to fine-tune in subspaces spanned by these parameters. all of our experiments have been performed using a corpus of publications from hep. the usage of the extraction algorithm on a different corpus would require tuning the parameters for the specific domain of application. for the area of hep, we can also consider preparing several sets of execution parameters varying by decade of document publication or by other easy to determine characteristics. subsequently, we could decide which extraction method to run, based on those metrics. in addition to a better tuning of the existing heuristics, there are improvements that can be made at the level of the algorithm. for example, we could mention extending the process of clustering text parts. in the current implementation, the margins by which textual operations are extended during the clustering process are fixed as algorithm parameters. this approach proved to be robust in most cases. in fact, distances between text lines tend to be different depending on the currently utilized style. every text portion tends to have one style that dominates. an improved version of the text-clustering algorithm could use local rather than global properties of the content. this would not only allow to correctly handle the entire document written using different text styles, but also help to manage cases of single paragraphs differing from the rest of the content. another important, not-yet-implemented improvement related to figure metadata is the automatic extraction of figure references from the text content. important information about figure content might be stored in the surroundings of the place where publication text refers to a figure. furthermore, the metadata could be extended by the usage of some type of classifier that would assign a graphics type to the extracted result. currently, we are only distinguishing between tables and figures based on simple heuristics involving number and type of graphical areas and the text inside of the detected caption. in the future, we could detect line-plots from photos, histograms and so on. such a classifier could be implemented using artificial intelligence techniques such as support vector machines.31 finally, partial results of the figures extraction algorithm might be useful in performing other pdf analyses: • the usage of clustered text areas could allow a better interpretation and indexing of textual content stored in digital libraries with full-text access. clusters of text tend to describe automatic extraction of figures from scientific publications in high-energy physics | praczyk, nogueras-iso, and mele 50 logical parts like paragraphs, section and chapter titles, etc. a simple extension of the current schema could allow the extraction of predominant formatting style of the text encoded in a page area. text parts written in different styles could be indexed in a different manner giving for instance more importance to segments written with larger font. • we mentioned that the algorithm detects not only figures, but also tables. a heuristic is being used in order to distinguish tables from different types of figures. our present effort concentrates on correct treatment of figures, but a useful extension could allow extraction of different types of entities. for instance, another common type of content ubiquitous in hep documents are mathematical formulas. thus, in addition to figures, it would be important to extract tables and formulas in structured format allowing a further processing. the internal architecture of the implemented prototype of the figure extractor allows easy implementation of extension modules which can compute other properties of pdf documents. acknowledgements this

was substantially different in the 1990s as the world wide web was only in its initial development. at that time, public libraries essentially experimented with publicaccess internet and computer

adopters of internet-based technologies and have provided public access to the internet and computers since the early 1990s.1 in 1994, 20.9 percent of public libraries were connected to the internet, and 12.7 percent offered public-access computers. by 1998, internet connectivity in public libraries grew to 83.6 percent, and 73.3 percent of public libraries provided public internet access.2 the landscape of public-access internet and computing was substantially different in the 1990s, as the world wide web was only in its initial development. at that time, public libraries essentially experimented with public-access internet and computer services, largely absorbing this service into existing service and resource provision without substantial consideration of the management, facilities, staffing, and other implications of public-access technology (pat) services and resources.3 using case studies conducted at thirty-five public libraries in five geographically dispersed and demographically diverse states, this article explores the implications for public libraries of the provision of pat. the researcher also conducted interviews with state library agency staff prior to visiting libraries in each state. the goals of this article are to n explore the level of support pat requires within public libraries; n explore the implications of pat on public libraries, including management, building planning, staffing, and other support issues; n explore current pat support practices; n identify issues and challenges public libraries face in maintaining and supporting their pat infrastructure; and n identify factors that contribute to successful pat practices. this article seeks to look beyond the provision of pat by public libraries and review issues and practices associated with pat–provision resources. while much research focuses on the amount of public access that public libraries provide, little offers a view of the effect of public access on libraries. this article provides insights into some of the costs, issues, and challenges associated with public access, and it concludes with recommendations that require continued exploration. n literature review quickly over time, public libraries increased their public-access provision substantially (see figures 1 and 2). connectivity grew from 20.9 percent in 1994 to nearly 100 percent in 2006.4 moreover, nearly all libraries that connected to the internet offered public-access internet services. simultaneously, the average number of publicaccess computers grew from 1.9 per public library in 1996 to 12 per public library in 2007.5 accompanying and in support of the continual growth of basic connectivity and computing infrastructure was a demand for broadband connectivity. indeed, since 1994, connectivity has progressed from dial-up phone lines to leased lines and other forms of high-speed connectivity. the extent of the growth in public-access services within public libraries is profound and substantive, leading to the development of new internet-based service roles for public libraries.6 and public access to the internet through public libraries provides a number of community benefits to different populations within served communities.7 overlaid onto the public-access infrastructure is an increasingly complex service mix that now includes access to digital content (e.g., databases and digital john carlo bertot (jbertot@umd.edu) is professor and director of the center for library innovation in the college of information studies at the university of maryland, college park. 82 information technology and libraries | june 2009 libraries), integrated library systems (ilss), voice over internet protocol (voip), digital reference, and a host of other services and resources—some for public access, others for back-office library operations. and patrons do use these services in increasing amounts—both in the library and in everyday life.8 in fact, 82.5 percent of public libraries report that they do not have an adequate number of public-access computers some or all of the time and have resorted to time limits and wireless access to extend public-access services.9 by 2007, as connectivity and public-access computer infrastructure grew, so ensued the need to provide a range of publicly available services and resources: n 87.7 percent of public libraries provide access to licensed databases n 83.4 percent of public libraries offer technology training n 74.1 percent of public libraries provide e-government services (e.g., locating government information and helping patrons complete online applications) n 62.5 percent of public libraries provide digital reference services n 51.8 percent of public libraries offer access to e-books10 the list is not exhaustive, but illustrative, since libraries do offer other services such access to homework resources, video content, audio content, and digitized collections. as public libraries expanded these services, management realized that they needed to plan and evaluate technology-based services. over the years, a range of technology management, planning, and evaluation resources emerged to help public libraries cope with their technology-based resources—those both publicly available and for administrative operations.11 but increasingly, public libraries report the strain that pat services promulgate. this centers on four key areas: n maintenance and management. the necessary maintenance and management requirements of pat places an additional burden on existing staff, many of whom do not possess technology expertise to troubleshoot, fix, and support internet-based services and resources that patrons access. n staff. libraries consistently cite staff expertise and availability as a barrier to the addition, support, and management of pat. indeed, as described in previous sections, some libraries have experienced a decline in library staff. n finances. there is evidence of stagnant funding for libraries at the local level as well as a shift in expenditures from staff and collections to operational costs such as utilities and maintenance. n buildings. the buildings are inadequate in terms of space and infrastructure (e.g., wiring and cabling) to support additional public access.12 this article explores these four areas through a sitevisit method in an effort to go beyond a quantitative assessment of pat within the public library community. though related in terms of topic area and author, this study was conducted separately from the public library internet surveys conducted since 1994 and offers insights into the provision of pat services and resources that a national survey cannot explore in such depth. figure 1. public-access internet connectivity from 1994 through 2008 figure 2. public-access internet workstations from 1996 through 2008 public access technologies in public libraries | bertot 83 n method the researcher visited thirty-five public libraries in five geographically and demographically diverse states between october 2007 and may 2008. the states were in the west, southwest, southeast, and mid-atlantic regions. the libraries visited included urban, suburban, rural, and native american public libraries that served populations ranging from a few hundred to more than half a million. the communities that the libraries served varied in terms of poverty, race, income, age, employment, and education demographics. prior to visiting the public library sites, the researcher conducted interviews with state library agency staff to better understand the public library context within each state and to explore overall pat issues, strategies, and other factors within the state. the following research questions guided the site visits: n what are the community and library contexts in which the library provides pat? n what are the pat services and resources that the library makes available to its community? n what pat services and resources does the library desire to provide to its community? n what is the relationship between provided and desired pat and the effect on the library (e.g., staff, finances, the building, and management)? n what are the perceived benefits to the library and its community gains through pat in the library? n what are the issues and barriers that the library encounters in providing pat services and resources? n how does the library manage and maintain its pat? the researcher visited each library for four to six hours. during that time, he interviewed the library director and/or branch manager and technology support staff (either a specific library position, designated library employee, or city or county it staff person), toured the library facility, and conducted a brief technology inventory. at some libraries, the researcher was able to meet with community partners that in some way collaborated with the library to provide pat services and resources (e.g., educational institutions that collaborated with libraries to provide access to broadband or volunteers who conducted technology training sessions). interviews were recorded and transcribed, and the technology inventories were entered into a microsoft excel spreadsheet for analysis. the transcripts were coded using thematic content analytic schemes to allow for the identification of key issues regarding pat areas.13 this approach enabled the researcher to use an iterative site-visit strategy that used findings from previous site visits to inform subsequent visits. to ensure valid and reliable data, the researcher used a three-stage strategy: 1. site-visit reports were completed and sent to th libraries for review. corrections from libraries were incorporated into a final site-visit report. 2. a final state-based site-visit report was compiled for distribution to state library agency staff and also incorporated their corrections. this provided a state-level reliability and validity check. 3. a summary of key findings was distributed to six experts in the public library technology environment, three of which were public library technology managers and three of which were technology consultants who worked with public libraries. in combination, this approach provided three levels of data quality checks, thus providing both internal (library and state) and external (technology expert) support for the findings. the findings in this article are limited to the libraries visited and interviews conducted with public librarians and state library agency staff. however, themes emerged early during the site-visit process and were reinforced through subsequent interviews and visits across the states and libraries visited. in addition, the use of external reviewers of the findings lends additional, but limited, support to the findings. n findings this section presents the results of the site visits and interviews with state library agency staff and public librarians. the article presents the findings by key areas surrounding pat in public libraries. the public-access context public libraries have a range of pat installed in their libraries for patron use. these technologies include public-access computers, wireless (wifi) access, ilss, online databases, digital reference, downloadable audio and video, and others. many of these services and resources are also available to patrons from outside library buildings, thus extending the reach (and support issues) of the library beyond the library’s walls. in addition, when libraries do not provide direct access to resources and services, they serve as access points to those services, such as online gaming and social networking. while libraries can and do deploy a number of technologies for public use, it is possible to group these 84 information technology and libraries | june 2009 technologies broadly into two overlapping categories: n hardware. library pat hardware can include public-access computers, public-access computing registration (i.e., reservation) systems, self-checkout stations, printers, faxes, laptops, and a range of other devices and systems. some of these technologies may have additional devices, such as those required for persons with disabilities. within the hardware grouping are networking technologies that include a range of hardware and software to enable a range of library networks to run (e.g., routers, hubs, switches, telecommunications lines, and networking software). n software. software can include device operating system software (e.g., microsoft windows, mac os, and linux), device application software (e.g., microsoft office, openoffice, graphics software, audio software, e-book readers, assistive software, and others), and functional software (e.g., web browsers, online databases, and digital reference). in short, public libraries make use of a range of technologies that the public uses in some way. each type of technology requires skills, management, implementation, and maintenance, all of which are discussed later. in the building, all of these products and services come together at the library’s public-access computers, or patron mobile device if wifi is available. moreover, patrons increasingly want to use their portable devices (e.g., usb drives, ipods, and others) with library technology. this places pressure on libraries to not just offer public-access computers, but also to support a range of technologies and services. thus the environment in which libraries offer pat is complex and requires substantial technical expertise, support, and maintenance in key areas of applications, computers, and networking. moreover, as discussed below, patrons are increasingly demanding market-based approaches to pat. these demands—which are largely about single-point access to a range of information services and resources—are often at odds with library technology that is based on stove-piped approaches (e.g, ils, e-books, and licensed resources) and that do not necessarily lend themselves to seamless integration. n external pressures on pats the advent and increased use by the public of google, amazon, itunes, youtube, myspace, second life, and other networked services affects public libraries in a number of ways. this article discusses these services and resources from the perspective of an information marketplace of which the public library is one entrant. interviewed librarians overwhelmingly indicated that users now expect library services to resemble those in the marketplace. users expect the look and feel, integration, service capabilities, interactivity, and personalization and customization that they experience while engaging in social networking, online searching, online purchasing, or other online activities. and within the library building, patrons expect the services to integrate at the public-access computer entry point—not distributed throughout the library in a range of locations, workstations, or devices. said differently, they expect to have a “mylibrary.com” experience that allows for seamless integration across the library’s services but also facilitates the use of personal technologies (e.g., ipods, mp3 players, and usb devices). thus users expect the library’s services to resemble those services offered by a range of information service providers. importantly, however, librarians indicated that library systems on which their services and resources reside by and large do not integrate seamlessly—nor were they designed to do so. public-access computers are gateways to the internet; the ils exists for patrons to search for and locate library holdings; and online databases, e-books, audiobooks, etc., are extensions of the library’s holdings but are not physical items under a library’s control and thus subject to a vendor’s information and business models. while library vendors and the library community are working to develop more integrated products that lead users to the information they seek, the technology is under development. there are three significant issues that libraries face because of market pressures: (1) the pressures all come together at a single point—the public-access computer; (2) users want a customized experience while using technology designed for the general public, not the individual user; and (3) users have choices in the information marketplace. one participant indicated, “if the library cannot match what users have access to on the outside, users will and do move on.” managing and maintaining public access managing the public-access computer environment for public libraries is an growing challenge. there are a number of management areas with which public librarians contend: n public-access computers—the computers and laptops (if applicable) themselves, which can include anything from keyboards and mice to troubleshooting a host of computer problems (it is important to note that these may be computers that often vary in age and composition, come from a range of vendors, run different operating systems, and often public access technologies in public libraries | bertot 85 have different application software versions). n peripheral management—the printers, faxes, scanners, and other equipment that are part of the library’s overall public access infrastructure. n public-access management software or systems—these may include online or in-building computer-based reservations (which encompasses specialized reservations such as teen machines, gaming computers, computers for seniors, and so on), time management (set to the library’s decided-upon time allotment), filtering, security, logins, virtual machines, etc. n wireless access—this may include logins and configurations for patrons to gain access to the library’s wireless network. n bandwidth management—this may include the need to allocate bandwidth differently as needs increase and decrease in a typical day. n training and patron assistance—for a vast array of services such as databases, online searching, e-government (e.g., completing government forms and seeking government information), and others. training can take place formally through classes, but also through point-of-use tutorials requested by patrons. to some extent, librarians commented that, while they do have issues with the public-access computers themselves from time to time, the real challenges that they face regard the actual management of the publicaccess environment—sign-ups, time limits, cost recovery for print jobs, helping patrons, and so on. one librarian commented that “the computers themselves are pretty stable. we don’t really have too many issues with them per se. it’s everything that goes into, out from, or around the computer that creates issues for us.” as a result of the management challenges, several libraries have adopted turn-key solutions, such as public-access management systems (e.g., comprise technology’s smart access manager [http://www.comprisetechnologies .com/product_29.html]) and all-encompassing public computing management systems that include networking and desktops (e.g., userful’s discoverstations [http:// userful.com/libraries/]). these systems allow for an allin-one sign-up, print cost recovery, filtering (if desired), and security approach. also, the discoverstations are a linux-based, all encompassing public-access management environment. a clear advantage to the discoverstation approach is that the discoverstation is connected to the internet and is accessible by userful staff remotely to update software and perform other maintenance functions. they also use open-source operating and application software. while these solutions do provide efficiencies, they also can create limitations. for example, the discoverstations are a thin-client system and are dependent on the server for graphics and memory, thus limiting their ability to access gaming and social-networking sites. the smart access manager, and similar programs, can rely on smart cards or other technology that users must purchase to print. another limitation is that the time limits are fixed, and, while users get warnings as time runs out, the session can end abruptly. these approaches are by and large adopted by libraries to ease the management associated with public-access computers and let staff concentrate on other duties and responsibilities. one librarian indicated that “until we had our management system, we would spend most of the day signing people up for the computers, or asking them to finish their work for the next person in line.” n planning for pat services and resources public libraries face a number of challenges when planning for pat services and resources. this is primarily because pat planning involves more than computers. any planning needs to encompass n building needs, requirements, limitations, and design; n technology assessment that considers the library’s existing technology, technology potential, current practices, and future trends; n planning for and supporting multiple technology platforms; n telecommunications and networking; n services and resources available in the marketplace—those specifically for libraries and those more broadly available to consumers and used by patrons; n specific needs and requirements of technology (e.g., memory, disk space, training, other); n requirements of other it groups with which the library may need to integrate, for example, city or county technology mandates; n support needs, including the need to enter into maintenance agreements for computer, network, and other equipment and software; n staff capabilities, such as current staff skill sets and their ability to handle the technologies under review or purchased; and n policy, such as requirements to filter because of local, state or federal mandates. the above list may not be exhaustive, but rather based on the main items that librarians identified during the site visits, and they serve to provide indicators of the challenges those planning library it initiatives face. 86 information technology and libraries | june 2009 n the endless upgrade and planning one librarian likened the pat environment to “being a gerbil on a treadmill. you go round and round and never really arrive,” a reference to the fact that public libraries are in a perpetual cycle of planning and implementing various pat services and resources. either hardware needs to be updated or replaced, or there is a software update that needs to be installed, or libraries are looking to the next technology coming down the road. in short, the technology planning to implementation cycle is perpetual. the upgrade and replacement cycle is further exacerbated by the funding situation in which most public libraries find themselves. increasingly, public library local and state funding, which combined can account for more than 90 percent of library funding, is flat or declining.14 the most recent series of public library internet studies indicates an increase in reliance by public libraries on fees and fines, fundraising, private foundation, and grant funding to finance collections and technology within libraries.15 this places key aspects of library operations in the realm of unreliable and one-time funding sources, thus making it difficult for libraries to develop multiyear plans for pat. n multiple support models to cope with pat management and maintenance issues, public libraries are developing various support strategies. the site visits found a number of technology-support approaches in effect, ranging from no it support to highly centralized statewide approaches. the following list describes the technology-support models encountered during the site visits: 1. no technology support. libraries in this group have neither technology-support staff nor any type of organized technology-support mechanism with existing library staff. nor do they have access to external support providers such as county or city it staff. libraries in this group might rely on volunteers or engage in ad hoc maintenance, but by and large have no formal approach to supporting or maintaining their technology. 2. internal library support without technology staff. in this model, the library provides its own technology support but does not necessarily have dedicated technology staff. rather, the library has designated one or more staff members to serve as the it person. usually this person has an interest in technology but has other primary responsibilities within the library. there may be some structure to the support—such as updating software (e.g., windows patches) once a week at a certain time— but it may be more ad hoc in approach. also, the library may try to provide its designated it person(s) with training to develop his or her skills further over time. 3. internal library support with technology staff. in this model, the library has at least one dedicated it staff person (partor full-time) who is responsible for maintaining and planning the library’s pat environment. the person may also have responsibilities for network maintenance and a range of technology-based services and resources. at the higher end of this approach are libraries with multiple it staff with differing responsibilities, such as networking, telecommunications, public-access computers, the ils, etc. libraries at this end of the spectrum tend to have a high degree of technology sophistication but may face other challenges (i.e., staffing shortages in key areas). 4. library consortia. over the years, public libraries have developed consortia for a range of services— shared ilss, resource sharing, resource licensing, and more. as public-library needs evolve, so too do the roles of library consortia. consortia increasingly provide training and technology-support services, and may be funded through membership fees, state aid, or other sources. 5. technology partners. while some libraries may rely on consortia for their technology support, others are seeking libraries that have more technology expertise, infrastructure, and abilities with whom to partner. this can be a fee-for-service arrangement that may involve sharing an ils, a maintenance agreement for network and public-access computer support, and a range of services. these arrangements allow the partner libraries to have some input into the technology planning and implementation processes without incurring the full expense of testing the technologies, having to implement them first, or hiring necessary staff (e.g., to manage the ils). the disadvantage to this model is that the smaller partner libraries are dependent on the technology decisions that the primary partner makes, including upgrade cycles, technology choices, migration time frames, etc. 6. city, county, or other agency it support. as city or county government agencies, some libraries receive technology support from the city or county it department (or in some cases the education department). this support ranges from a full slate of services and support available to the library to support only for the staff network and computers. public access technologies in public libraries | bertot 87 even at the higher end of the support spectrum, librarians gave mixed reviews for the support received from it agencies. this was primarily because of competing philosophies regarding the pat environment, with public librarians wanting an open-access policy to allow users access to a range of information service and resources and it agency staff wanting to essentially lock down the public-access environment and thus severely limit the functionality of the public-access computers and network services (i.e., wireless). other limitations might include prescribed pat, specified vendors, and bidding requirements. 7. state library support. one state library visited provides a high degree of service through its statewide approach to supporting public-access computing in the state’s public libraries. the state library has it staff in five locations throughout the state to provide support on a regional level but also has additional staff in the capital. these staff offer training, inhouse technical support, phone support, and can remote access the public-access computers in public libraries to troubleshoot, update, and perform other functions. moreover, this state built a statewide network through a statewide application to the federal e-rate program, thus providing broadband to all libraries. this model extends the availability of qualified technical support staff to all public libraries in the state—by phone as well as in person if need be. as a result, this enables public libraries to concentrate on service delivery to patrons. it is important to note that there are combinations of the above models in public libraries. for example, some libraries support their public-access networks and technology while the county or city it department supports the staff network and technology. it is clear, however, that there are a number of models for technology support in public libraries, and likely more than are presented in this article. the key issue is that public libraries are engaging in a broad spectrum of strategies to support, maintain, and manage their pat infrastructure. also of significance is that there are public libraries that have no technology-support services that provide pat services and resources. these libraries tend to serve populations of less than ten thousand, are rural, have fewer than five full-time equivalents (ftes), and are unlikely to be staffed by professional librarians. staff needs and pressures the study found a number of issues related to the effect of pat on library staff. this section of the findings discusses the primary factors affecting library staff as they work in the public-access context. n multiple skills needed not only is the pace of technological change increasing, but the change requires an ever-increasing array of skills because of the complexity of applications, technologies, and services. an example of such complexity is the library opac or ils. visited libraries indicated that such systems are becoming so complex and technologically sophisticated that there is a need for a full-time staff person to run and maintain the library ils. given the range of hardware, software, and networking infrastructure, as well as planning and pat management requirements, public librarians need a number of skills to successfully implement and maintain their pat environments. moreover, the skill needs depend on the librarian’s position—for example, an actual it staff person versus a reference librarian who does double duty by serving as the library’s it person. the skills required fall into technology, information literacy, service and facilities planning, management, and leadership and advocacy areas: n technology o general computer troubleshooting o basic maintenance, such as mouse and keyboard cleaning o basic computer repair, such as memory replacement, floppy drive replacement, disk defragmentation, etc. o basic networking, such as troubleshooting an “internet” issue versus a computer problem o telecommunications so as to understand the design and maintenance of broadband networks o integrated library systems o web design n information literacy o searching and using internet-based resources o searching and using library licensed resources o training patrons on the use of the publicaccess computers, general internet resources, and library resources o designing curriculum for various patron training courses n services and facilities planning o technology plan development and implementation (including budgeting) o telecommunications planning (including 88 information technology and libraries | june 2009 e-rate plan and application development) o building design so as to accommodate the requirements of public access technologies n management o license and contract negotiation for licensed resources, various public-access software and licenses, and maintenance agreements (service and repair agreements) o integration of pat into library operations o troubleshooting guidelines and process o policy development, such as acceptable use, filtering, filtering removal requests by patrons, etc. n leadership and advocacy o grant writing and partnership development so as to fund pat services and resources and extend out into the community that the library serves o advocacy so as to be able to demonstrate the value of pat in the library as a community good o leadership so as to build a community approach to public access with the library as one of the foundational institutions these items provide a broad cross section of the skills that public library staff may need to offer a robust pat environment. in the case of smaller, rural libraries, these requirements in general fall to the library director—along with all other duties of running the public library. in libraries that have separate technology, collections development, and other specialized staff, the skills and expertise may be dispersed throughout various areas in the library. n training public librarians receive a range of technology training— including none at all. in some cases, this might be a basic workshop on some aspect of technology at a state library association annual meeting or a regional workshop hosted by the library’s consortium. it could be an online course through webjunction (http://www.webjunction .org/). it could be a one-on-one session with a vendor representative or colleague. or it could be a formal, multiday class regarding the latest release of an ils. if available, public librarians have access to technology training that can take many forms, has a wide array of content (basic to expert), and can enhance staff knowledge about it with varying degrees of success. an issue raised by librarians was that having access to training and being able to take advantage of training are two separate things. regardless of the training delivery medium, librarians indicated that they were not always able to get release time to attend a training session. this was particularly the case for small, rural libraries that had less than five ftes spread out over several part-time individuals. for these staff to take advantage of training would require a substitute to cover public-service hours—or shut down the library. funding information technology as one might expect, there was a range of technology budgets in the public libraries visited or interviewed— from no technology budget to a substantial technology budget, and many points in between. some libraries had a dedicated it budget line item, others had only an operating budget out of which they might carve some funds for technology. libraries with dedicated it budgets by and large had at least one it staff person; libraries with no it budget largely relied on a staff person responsible for other library functions to manage their technology. in the smallest libraries, the library director served as the technology specialist in addition to being the general library operation manager. some libraries have established foundations through which they can raise funds for technology, among other library needs. many seek grants and thus devote substantial effort to seeking grant initiatives and writing grant proposals. some libraries held fundraisers and worked with their library friends groups to generate funds. other libraries engage in all of the above efforts to provide for their pat infrastructure, services, and resources. in short, there are several budgetary approaches public libraries use to support their pat environment. critical to note is that a number of libraries are increasingly relying on nonrecurring funds to support pats, a fact corroborated by the 2007 and 2008 public library internet surveys.16 the buildings when one visits public libraries, one is immediately struck by the diversity in design, functionality, and architecture of the buildings. public libraries often reflect the communities that they serve not only in the collection and service, but also in the facilities. this diversity serves the public library community well because it allows for a custom approach to libraries and their community. the building design, however, can also be a source of substantial challenge for public libraries. the increased integration of technology into library service places a range of stresses on buildings—physical space for workstations and other equipment and specialized furniture, power, server rooms, and cabling, for example. along with the library-based technology requirements come those of patrons—particularly the need for power so that public access technologies in public libraries | bertot 89 patrons may plug in their laptops or other devices. also important to note is that the building limitations also extend to staff and their access to computing and networked technologies. a number of librarians commented that they are “simply at capacity.” one librarian summed it up by stating that “there’s no more room at the inn. unless we start removing parts of our collection, we don’t have any more room for workstations.” another said that, “while we do have the space to add more computers, we don’t have enough power or outlets to support them. and, with our building, it’s not a simple thing to add.” in short, many libraries are reaching, or have reached, a saturation point as to just how much pat they can support. n discussion and implications over time, pat services have become essential services that public libraries provide their communities. with nearly all public libraries connected to the internet and offering public-access computers, the high percentage of libraries that offer internet-based services and resources, the overall usage of these resources by the public,17 and 73 percent of public libraries reporting that they are the only free provider of pat in their communities, it is clear that the provision of pat services is a key and critical service role that public libraries offer.18 it is also clear, however, that the extent to which public libraries can continue to absorb, update, and expand their pat depends on the resolution of a number of staffing, financial, maintenance and management, and building barriers. in a time of constrained budgets, it is unlikely that libraries will receive increased operational funding. indeed, reports of library funding cuts are increasing in the current economic downturn, which affects the ability of libraries to increase, or significantly update, staff—particularly in the areas of technology, licensing additional resources, procuring additional and new computers, and purchasing and offering expanded services such as digital photography, gaming, or social networking.19 moreover, the same financial constraints can affect the ability of libraries to raise capital funds for building improvements and new construction. funding also has an effect on the training that public libraries can offer or develop for their staff. and training is becoming increasingly important to the success of pat services and resources in public libraries—but not just training regarding the latest technologies. rather, there is a need for training that provides instruction on the relationship between the level of pat services and resources a library can or desires to provide and advocacy; broadband, computing, and other needs; technology planning and management; collaboration and partnering; and leadership. the public library pat environment is complex, encompasses a number of technologies, and has ties to many community services and resources. training programs need to reflect this complexity. the continued provision of pat services in public libraries is increasingly burdensome on the public library community, and the pressures to expand their pat services and resources continues to grow—particularly as libraries report their “sole provider” of free pat status in their communities. the successful libraries in terms of pat services and resources visited had staff that could n understand pat (both in terms of functionality and potential); n think creatively across the technology and library service spectrum; n integrate online content, pat, and library services; n articulate the value of pat as an essential community need and public library service; n articulate the role of the perception of the library by its community as a critical bridge to online content; n demonstrate leadership within the community and library; n form partnerships and extend pat services and resources into the community; and n raise funds and develop other support mechanisms to enhance pat services and resources in the library and throughout the community. in short, successful pat in libraries was being redefined in the context of communitywide pat service and resource provision. this approach not only can lead to a more robust community pat infrastructure, but it also lessens the library’s burden of pat service and resource provision. but equally important to note is that the extent to which all public libraries can engage in these activities on their own is unclear. indeed, several libraries visited were struggling to maintain basic pat service levels and indicated that increasing pat services came at the expense of other library services. “we’re trying to meet demand,” one librarian said, “but we have too few computers, too slow a connection, and staff don’t always know what to do when things go wrong or someone comes in talking about the latest technology or website.” for some libraries, therefore, quality pat services that meet community needs are simply out of reach. thus another implication and finding of the study is the need for libraries to explore other models of support for their pat environments—for example, using the services of a regional cooperative, if available; if none is available, libraries could form their own cooperative for resource sharing, technology support, and other aspects of pat service provision. the same approach could be 90 information technology and libraries | june 2009 taken within a city or county to enhance technology support throughout a region. another approach would be to outsource a library’s pat support and maintenance to a nearby library with support staff in a fee-for-service approach. there are a number of approaches that libraries could take to support their pat infrastructure. a key point is that libraries need to consider pat service provision in a broader community, regional, or state context, and the study found some libraries doing so. the need to avail staff of the skills required to truly support pat was a recurring theme throughout the site visits. approaches and access to training varied. for example, some state libraries provided—either directly or through the hiring of consultants and instructors—a number of technology-related courses taught in regional locations. an example of this approach is california’s infopeople project (http://www.infopeople .org/). some state libraries subscribed to webjunction (http://www.webjunction.org/), which provides access to online instructional content. online manuals provided by compumentor through a grant funded by the bill and melinda gates foundation aimed at helping rural libraries support their pat (www.maintainitproject.org) are another resource. beyond technology skills training, however, is the need for technology planning, effective communication, leadership, value demonstration, and advocacy. the extent to which leadership, advocacy, and library marketing, for example, are able to be taught remains a question. all of these issues take place with the backdrop of an economic downturn and budgetary constraints. increased operating costs created through inflation and higher energy costs place substantial pressures on public libraries simply to maintain current levels of service— much less engage in the additional levels of service that the pat environment brings. indeed, as the 2008 public library funding and technology access study demonstrated, public libraries are increasingly funding their technology-based services through non-recurring funds such as fines and fundraising activities.20 thus, the ability of public libraries to provide robust pat services and resources is increasingly limited unless such service provision comes at the expense of other library services. alone, the financial pressures place a high burden on public libraries. combined with the building, staffing, skills, and other constraints reported by public libraries, however, the emerging picture for library pat services and resources is one of significant challenge. n three key areas for additional exploration the findings from the study point to the need for additional research and exploration of three key services areas and issues related to pat support and services: 1. develop a better understanding of success in the pat environment. this study and the 2006 study by bertot et al. point to what is required for libraries to be successful in a networked environment.21 in fact, the 2007 public libraries and the internet report contained a section entitled “the successfully networked public library,” which offered a range of checklists for public libraries (and others) to consider as they planned and implemented their networked services.22 this study identified additional success factors and considerations focused specifically on the public access technology environment. together, these efforts point to the need to better understand and articulate the critical success factors necessary for public libraries to plan, implement, and update their pat given current service contexts. this is particularly necessary in the context of meeting user expectations and needs regarding networked technologies and services. 2. further identify technology-support models. this study uncovered a number of different technologysupport models implemented by public libraries. undoubtedly there are additional models that require identification. but, more importantly, there is a need to further explore how each technologysupport model assists libraries, under what circumstances, and in what ways. some models may be more or less appropriate on the basis of the service context of the library—and that is not clearly understood at this time. 3. levels of service capabilities. an underlying theme throughout this research, and one that is increasingly supported by the public library and the internet studies, is that the pat service context is essentially a continuum from low service and capability to high service and capability. there are a number of factors contributing to where libraries may lie on the success continuum—funding, management, leadership, attitude, skills, community support, and innovation, to name a few. this continuum requires additional research, and the research implications could be profound. emerging data indicate that there are public libraries that will be unable to continue to evolve and meet the increased demands of the networked environment, both in terms of staff and infrastructure. public libraries will have to make choices regarding the provision of pat services and resources in light of their ability to provide high-quality services (as defined by their service communities). for better or worse, the technology environment continually evolves and requires new technologies, management, and support. that is, public access technologies in public libraries | bertot 91 and will continue to be, the nature of public access to the internet. though there are likely other issues worthy of exploration, these three are critical to further our understanding of the pat environment and public library roles and issues associated with the provision of public access. n conclusion the pat environment in which public libraries operate is increasingly complex and continues to grow in funding, maintenance and management, staffing, and building demands. public libraries have navigated this environment successfully for more than fifteen years; however, stresses are now evident. libraries rose quickly to the challenge of providing public-access services to the communities that they serve. the challenges libraries face are not necessarily insurmountable, and there are a range of tools designed to help public libraries plan and manage their public-access services. these tools, however, place the burden of public access, or assume that the burden of public access in placed, on the public library. given increased operating costs because of inflation, the continual need to innovate and upgrade technologies, staff technology skills requirements, and other factors discussed in this article, libraries may not be in a position to shoulder the burden of public access alone. thus there is a need to reconsider the extent to which pat provision is the sole responsibility of the library; perhaps there is a need to integrate and expand public access throughout a community. the potential of such an approach can benefit a community through an integrated and broader access strategy, but also can relieve the pressure on the public library as the sole provider of public access. n acknowledgement this reserach was made possible in part through the support of the maintianit project (http://www.maintainit project.org/), an effort

on staffing models in academic libraries ping fu and moira fitzgerald information technology and libraries | september 2013 47 abstract this analysis compares how the traditional integrated library system (ils) and the next-generation ils may impact system and technical services staffing models at academic libraries. the method used in this analysis is to select two categories of ilss—two well-established traditional ilss and three leading next-generation ilss—and compare them by focusing on two aspects: (1) software architecture and (2) workflows and functionality. the results of the analysis suggest that the nextgeneration ils could have substantial implications for library systems and technical staffing models in particular, suggesting that library staffing models could be redesigned and key librarian and staff positions redefined to meet the opportunities and challenges brought on by the next-generation ils. introduction today, many academic libraries are using well-established traditional integrated library systems (ilss) built on the client-server computing model. the client-server model aims to distribute applications that partition tasks or workloads between the central server of a library automation system and all the personal computers throughout the library that access the system. the client applications are installed on the personal computers and provide a user-friendly interface to library staff. however, this model may not significantly reduce workload for the central servers and may increase overall operating costs because of the need to maintain and update the client software across a large number of personal computers throughout the library. 1 since the global financial crisis, libraries have been facing severe budget cuts, while hardware maintenance, software maintenance, and software licensing costs continue to rise. the technology adopted by the traditional ils was developed more than ten years ago and is evidently outdated. the traditional ils does not have sufficient capacity to provide efficient processing for meeting the changing needs and challenges of today’s libraries, such as managing a wide variety of licensed electronic resources and collaborating, cooperating, and sharing resources with different libraries.2 ping fu (pingfu@cwu.edu), a lita member, is associate professor and head of technology services in the brooks library, central washington university, ellensburg, wa. moira fitzgerald (moira.fitzgerald@yale.edu), a lita member, is access librarian and assistant head of access services in the beinecke rare book and manuscript library, yale university, new haven, ct. mailto:pingfu@cwu.edu mailto:moira.fitzgerald@yale.edu a comparative analysis of the effect of the integrated library system on staffing models in academic libraries | fu and fitzgerald 48 today’s libraries manage a wide range of licensed electronic resource subscriptions and purchases. the traditional ils is able to maintain the subscription records and payment histories but is unable to manage details about trial subscriptions, license negotiations, license terms, and use restrictions. some vendors have developed electronic resources management system (erms) products as standalone products or as fully integrated components of an ils. however, it would be more efficient to manage print and electronic resources using a single, unified workflow and interface. to reduce costs, today’s libraries not only band together in consortia for cooperative resource purchasing and sharing, but often also want to operate one “shared ils” for managing, building, and sharing the combined collections of members.3 such consortia are seeking a new ils that exceeds traditional ils capabilities and uses new methods to deliver improved services. the new ils should be more cost effective, should provide prospects for cooperative collection development, and should facilitate collaborative approaches to technical services and resource sharing. one example of a consortium seeking a new ils is the orbis cascade alliance, which includes thirty-seven universities, colleges, and community colleges in oregon, washington, and idaho. as a response to this need, many vendors have started to reintegrate or reinvent their ilss. library communities have expressed interest in the new characteristics of these next-generation ilss; their ability to manage print materials, electronic resources, and digital materials within a unified system and a cloud-computing environment is particularly welcome.4 however, one big question remains for libraries and librarians, and that is what implications the next-generation ils will have on libraries’ staffing models. little on this topic has been presented in the library literature. this comparative analysis intends to answer this question by comparing the nextgeneration ils with the traditional ils from two perspectives: (1) software architecture, and (2) workflows and functionality, including the capacity to facilitate collaboration between libraries and engage users. scope and purpose the purpose of the analysis is to determine what potential effect the next-generation ils will have on library systems and technical services staffing models in general. two categories of ilss were chosen and compared. the first category consists of two major traditional ilss: ex libris’s voyager and innovative interfaces’ millennium. the second category includes three nextgeneration ilss: ex libris’s alma, oclc’s worldshare management services (wms), and innovative interfaces’ sierra. voyager and millennium were chosen because they hold a large portion of current market shares and because the authors have experience with these systems. yale university library is currently using voyager, while central washington university library is using millennium. alma, wms, and sierra were chosen because these three next-generation ilss are produced by market leaders in the library automation industry. the authors have learned about these new products by reading and analyzing literature and vendors’ proposals, as well as information technology and libraries | september 2013 49 attending vendors’ webinars and product demonstrations. in the long run, yale university library must look for a new library service platform to replace voyager, verde, metalib, sfx, and other add-ons. central washington university library is affiliated with the orbis cascade alliance mentioned above. the alliance is implementing a new library management service to be shared by all thirty-seven members of the consortium. ex libris, innovative interfaces, oclc, and serials solutions all bid for the alliance’s shared ils. after an extensive rfp process, in july 2012 the orbis cascade alliance decided to choose ex libris’s alma and primo as their shared library services platform. the system will be implemented in four cohorts of approximately nine member libraries each over a two-year period, beginning in january 2013. the central washington university library is in the forth migration cohort, and their new system will be live in december 2014. it is important to emphasize that the next-generation ils has no local online public access catalog (opac) interface. vendors use additional discovery products as the discovery-layer interfaces for their next-generation ilss. specifically, ex libris uses primo as the opac for alma, while oclc’s worldcat local provides the front-end interface for wms. innovative interfaces offers encore as the discovery layer for sierra. as front-end systems, these discovery platforms provide library users with one-stop access to their library resources, including print materials, electronic resources, and digital materials. while these discovery platforms will also impact library organization and librarianship, they will have more impact on the way that end-users, rather than library staff, discover and interact with library collections. in this analysis, we focus on the effects that back-end systems such as alma, wms, and sierra will have on library organizational structure and staffing, rather than the end-user experience. as our sample only includes five ilss, the scope of the analysis is limited, and the findings cannot be universal or extended to all academic libraries. however, readers will gain some insight into what challenges any library may face when migrating to a next-generation ils. literature review a few studies have been published on library staffing models. patricia ingersoll and john culshaw’s 2004 book about systems librarianship describes vital roles that systems librarians play, with responsibilities in the areas of planning, staffing, communication, development, service and support, training, physical space, and daily operations. 5 systems librarians are the experts who understand both library and information technology and can put the two fields together to context. they point out that system librarians are the key players who ensure that a library stays current with new information technology. the daily and periodic operations for systems librarians include ils administration, server management, workstation maintenance, software and applications maintenance and upgrades, configuration, patch management, data backup, printing issues, security, and inventory. all of these duties together constitute the workloads of systems librarians. ingersoll and culshaw also emphasize that systems librarians must be proactive in facing constant changes and keep abreast of emerging library technologies. a comparative analysis of the effect of the integrated library system on staffing models in academic libraries | fu and fitzgerald 50 edward iglesias et al., based on their own experiences and observations at their respective institutions, studied the impact of information technology on systems staff.6 their book covers concepts such as the client-server computing model, web 2.0, electronic resource management, open-source, and emerging information technologies. their 2004 studies show that, tough there are many challenges inherent in the position, there are also many ways for system staff to improve their knowledge, skills, and abilities to adapt to the changing information technologies. janet guinea has also studied the roles of systems librarians at an academic library.7 her 2003 study shows that systems librarians act as bridge-builders between the library and other university units in the development of library-initiated projects and in the promotion of information technology-based applications across campus. another relevant study was conducted by marshall breeding at vanderbilt university in an investigation of the library automation market. his 2012 study compares the well-established, traditional ilss that dominate the current market (and are based on client-server computing architecture developed more than a decade ago) to the next-generation ilss deployed through multitenant software-as-a-service (saas) models, which are based on service-oriented architecture (soa).8 through this comparison, breeding indicates that next-generation ilss will differ substantially from existing traditional ilss and will eliminate many hardware and maintenance investments for libraries. the next-generation ils will bring traditional ils functions, erms, digital asset management, link resolvers, discovery layers, and other add-on products together into one unified service platform, he argues.9 he gave the next-generation ils a new term, library services platform.10 this term signifies that a conceptual and technical shift is happening: the next-generation ils is designed to realign traditional library functions and simplify library operations through a more inclusive platform designed to handle different forms of content within a unified single interface. breeding’s findings conclude that the next-generation ils provides significant innovations, including management of print and electronic library materials, reliance on global knowledge bases instead of localized databases, deployment through multitenant saas based on a service-oriented architecture, and the provision of a suite of application programming interfaces (apis) that enable greater interoperability and extensibility.11 he also predicts that the next-generation ils will trigger a new round of ils migration.12 method our method narrowed down the analysis for the implications of ilss on library systems and technical services staffing models to two major aspects: (1) software architecture, and (2) workflows and functionality, including facilitation of collaborations between libraries and user engagement. first, we analyzed two traditional ilss, voyager and millennium, which are built on a client-server computing model, deliver modular workflow functionality, and are implemented in our institutions. through the analysis, we determined how these two aspects affect library organizational structure and librarian positions designed for managing these modular tasks. then, information technology and libraries | september 2013 51 based on information we collected and grouped from vendors’ documents, rfp responses, product demonstrations, and webinars, we examined the next-generation ilss alma, wms, and sierra— which are based on soa and intended to realign traditional library functions and simplify library operations—to evaluate how these two factors will impact staffing models. to provide a more in-depth analysis, particularly for systems staffing models, we also gathered and analyzed online systems librarian job postings, particularly for managing the voyager or millennium system, for the past five years. the purpose of this compilation is to cull a list of typical responsibilities of systems librarians and then determine what changes may occur when they must manage a next-generation ils such as alma, wms, or sierra. data on job postings were gathered from online job banks that keep an archive of past listings, including code4lib jobs, ala joblist, and various university job listing sites. duplicates and reposts were removed. the responsibilities and duties described in the job descriptions were examined for similarities to determine a typical list. the data from all sources were gathered together in a single database to facilitate its organization and manipulation. specific responsibilities, such as administering an ils, were listed individually, while more general responsibilities for which descriptions may vary from one posting to another were grouped under an appropriate heading. to ensure complete coverage, all postings were examined a second time after all categories had been determined. we also used our own institutions as examples to support the analysis. the implications of ils software architecture on staffing models voyager and millennium are built on client-server architecture. libraries that use these ilss also use add-ons, such as erms and link resolvers, to manage their print materials and licensed electronic resources. the installation, configuration, and updates of the client software require a significant amount of work for library it staff. many libraries must allocate substantial staff effort and resources to coordinating the installation of the new software on all computers throughout the library that access the system. those libraries that allow staff to work remotely have experienced additional costs and it challenges. in addition, server maintenance, backups, upgrades, and disaster recovery also require excessive time and effort of library it staff. administering ilss, erms, and other library hardware, software, and applications is one of the primary responsibilities for a library systems department. positions such as systems librarian, electronic resource librarian, and library it specialist were created to handle this complicated work. at a very large library, such as yale university library, the systems group of library it is only responsible for voyager’s configuration, operation, maintenance, and troubleshooting. two other it support groups—a library server support group and a workstation support group—are responsible for installation, maintenance, and upgrade of the servers and workstations. specifically, the library server support group deals with the maintenance and upgrade of ils servers and the software and relational database running on the servers, while the workstation support group takes care of the installation and upgrade of the client software on hundreds of a comparative analysis of the effect of the integrated library system on staffing models in academic libraries | fu and fitzgerald 52 workstations throughout twenty physical libraries. at a smaller library, such as central washington university library, on the other hand, one systems librarian is responsible for the administration of millennium, including configuration, maintenance, backup, and upgrade on the server. another library it staff member helps install and upgrade the millennium client on about forty-five staff computers throughout its main library and two center campus libraries. comparatively, the next-generation ilss alma, wms, and sierra have a saas model designed by soa principles and deployed through a cloud-based infrastructure. oclc defines this model as “web-scale management services.”13 using this innovation, service providers are able to deliver services to their participating member institutions on a single, highly scalable platform, where all updates and enhancements can be done automatically through the internet. the different participating member institutions using the service can configure and customize their views of the application with their own brandings, color themes, and navigational controls. the participating member institutions are able to set functional preferences and policies according to their local needs. web-scale services reduce the total cost of ownership by spreading infrastructure costs across all the participating member institutions. the service providers have complete control over hardware and software for all participating member institutions, dramatically eliminating capital investments on local hardware, software, and other peripheral services. service providers can centrally implement applications and upgrades, integration across services, and system-wide infrastructure requirements such as performance reliability, security, privacy, and redundancy. thus participating member institutions are relieved from this burdensome responsibility that has traditionally been undertaken by their it staff.14 from this perspective, the next-generation ils will have a huge impact on library organizational structure, staffing, and librarianship. since the next-generation ils is implemented through the cloud-computing model, there is no requirement for local staff to perform the functions traditionally defined as “systems” staff activities, such as server and storage administration, backup and recovery administration, and server-side network administration. for example, the entire interfaces of alma and wms are served via web browser; there is no need for local staff to install and maintain clients on local workstations. therefore, if an institution decided to migrate to a next-generation ils, the responsibilities and roles of systems staff within the institution would need to be readdressed or redefined. we have learned from attending oclc’s webinars and product demonstrations that library systems staff would be required to prepare and extract data from their local systems during new systems implementation. they also would be required to configure their own settings such as circulation policies. however, after the migration, a systems staff member would likely serve as a liaison with the vendor. this would require, according to oclc’s proposal, only 10 percent of the systems staff’s time on an ongoing basis. through attending ex libris’s webinars and product demonstrations, we have learned that a local system administrator may be required to take on basic management processes, such as record-loading or integrating data from other campus systems. similarly, we have learned from innovative interfaces’ webinars and product demonstrations that sierra would still need local systems information technology and libraries | september 2013 53 expertise to perform the installations of the client software on staff workstations. sierra would require library it staff to perform administrative tasks like the user account administration and to support sierra in interfacing with local institution-specific resources. in general, as shown in table 1, local systems staff could be freed from the burdensome responsibility of administering the traditional ils because of the software architecture of the nextgeneration ils. systems librarian responsibilities workload percentage traditional ils nextgen ils managing ils applications,

responsibilities and the approximate percentage of time devoted to each function are slightly readjusted based on the compiled descriptions of the systems librarian job postings we collected and analyzed from the internet and from vendors’ claims. a total of 47 position a comparative analysis of the effect of the integrated library system on staffing models in academic libraries | fu and fitzgerald 54 descriptions were gathered. the workload percentage is adopted from the job description of the systems librarian position at one of our institutions. our analysis shows that systems staff might reduce their workload by approximately 40 percent. therefore library systems staff could use their time to focus on local applications development and other library priority projects. however, it is important to emphasize that library systems staff should reengineer themselves by learning how to use apis provided by the next-generation ils so that they will be able to support the customization of their institutions’ discovery interfaces and the integration of the ils with other local enterprise systems, such as financial management systems, learning management systems, and other local applications. the implications of ils workflows and functionality on staffing models the typical workflow and functionality of both voyager and millennium are built on a modular structure. major function modules, called client modules, include systems administration, cataloging, acquisitions, serials, circulation, and statistics and reports. additionally, the traditional ils provides an opac interface for library patrons to access library materials and manage their accounts. millennium has an erms module built in as a component of their ils while ex libris has developed an independent erms as an add-on to voyager. the systems administration module is used to add system users and to set up locations, patron types, material types, and other library policies. the cataloging module supports the functions of cataloging resources, managing the authority files, tagging and categorizing content, and importing and exporting bibliographic records. the sophistication of the cataloging module depends primarily on the ils. the acquisitions module helps in the tracking of purchases and acquisition of materials for a library by facilitating ordering, invoicing, and data exchange with serial, book, and media vendors through electronic data interchange (edi). the circulation module is used to set up rules for circulating materials and for tracking those materials, allowing the library to add patrons, issue borrowing cards, and form loan rules. it also automates the placing of holds, interlibrary loan (ill), and course reserves. self-checkout functionality can be integrated as well. the serials module is essentially a cataloging module for serials. libraries are often dependent on the serials module to help them track and check-in serials. the statistics and reports module is used to generate reports such as circulation statistics, age of collection, collection development, and other customized statistical reports. a typical traditional ils comprises a relational database, software to interact with that database, and two graphical user interfaces—one for patrons and one for staff. it usually separates software functions into discrete modules, each of them integrated with a unified interface. the traditional ils’s modular design was a perfect fit for a traditional library organizational structure. the staff at central washington university library, for example, under the library administration, are organized into the following three major groups: public services, including the reference and circulation departments; technical and technology services, including the cataloging, collection development, serials & electronic resource, and systems departments; and information technology and libraries | september 2013 55 other library services and centers, including the government documents department, the music library, two center campus libraries, the academic and research commons, and the rare book collection & archive. each department has at least one professional librarian and other library staff members responsible for their daily operations. for example, the collection development librarian is responsible for the acquisition of print monographs and serials, while the electronic resource librarian is responsible for purchasing and managing licensed databases or e-journals. however, the next-generation ils significantly enhances and reintegrates the workflow of traditional ils functions. the functionality is quite different from the traditional ils’s modular structure. the design of the functionality stresses two principles: modularity and extensibility. it brings together the selection, acquisition, management, and distribution of the entire library collection. it provides a centralized data-services environment to its unified workflows for all types of library assets. one of the big enhancements of the next-generation ils is the acquisitions module, which enables the management of both print and electronic materials within a single unified interface, with no need to move between modules or multiple systems for different formats and related activities. for example, according to oclc, wms streamlines selection and acquisition processes via built-in access to worldcat records and publisher data. vendor, local, consortium, and global library data share the same workflows. wms automatically creates holdings for both physical and electronic resources. the worldcat knowledge-base simplifies electronic resource management and delivery. order data from external systems can be automatically uploaded. for consortium users, wms’s unified workflow and interface fosters efficient resource-sharing between different institutions whose holdings share a common format. similarly, ex libris’s alma has an integrated central knowledge base (ckb) that describes available electronic resources and packages, so there is no need to load additional descriptive records when acquiring electronic resources based on the ckb. the purchasing workflow manages orders for both print and electronic resources in a very similar way and handles some aspects unique to electronic resources, such as license management and the identification of an access provider. staff users can start the ordering process by searching the ckb directly and ordering from there. this search is integrated into the repository search, allowing a staff user to perform searches both in his or her institution as well as in the community zone, which holds the ckb. the next-generation ils provides unified data services and workflows, and a single interface to manage all physical, electronic, and digital materials. this will require libraries to rethink their acquisitions staffing models. for example, in small libraries could merge the acquisition librarian position and the electronic resource librarian position or reorganize the two departments. another functionality enhancement of the next-generation ils provides the authoritative ability for consortia users to manage local holdings and collections as well as shared resources. for example, wms’s single shared knowledge base eliminates the need for each library to maintain a copy of a knowledge base locally, because all consortia members can easily see what is licensed by other members of the consortia. cataloging records are shared at the consortium and global levels a comparative analysis of the effect of the integrated library system on staffing models in academic libraries | fu and fitzgerald 56 in real time. each institution immediately benefits from original cataloging records added to the system and from enhancements to existing records. authority control is built into worldcat, so there is no need to do authority processing against local bibliographic databases. with real-time circulation between libraries’ collections, there is no need to re-create bibliographic and item data in separate local systems. similarly, sierra enhances the traditional technical services workflows by providing a shared bibliographic database. whenever a member library performs selection or ordering, the library is able to determine if other consortia members have already selected, ordered, and cataloged the title. this may impact a local selection, allowing consortia members to more collectively develop their individual collections and reduce duplication. alma’s centralized metadata management service (mms) takes a very similar approach to wms and sierra, allowing several options for local control and shared cataloging, depending on an institution’s needs, while ex libris maintains authority files. very large institutions, for example, might manage some records in the local catalog and most records in a shared bibliographic database, while smaller institutions might manage all of their records in the shared bibliographic database. all these approaches require more collaboration and cooperation between consortia members. according to vendors’ claims on their proposals to the orbis cascade alliance, small institutions might not need to have a professional cataloger, since the cataloging process is simplified and it is therefore easier for paraprofessional staff to operate and copy bibliographic records from the knowledgebases of these ilss. in addition, the next-generation ils also allows library users to actively engage with ils software development. for example, by adding opensocial containers to the product, wms allows library developers to use api to build social applications called gadgets and add these gadgets to wms. one example highlighted by oclc is a gadget in the acquisitions area of wms that will show the latest new york times best sellers and how many copies the library has available for each of those titles. similarly, sierra’s open developer community will allow library developers to share ideas, reference code samples, and build a wide range of applications using sierra’s web services. also, sierra will provide a centralized online resource called sierra developer sandbox to offer a comprehensive library of documented apis for library-developed applications. all these enhancements provide library staff with new opportunities to redefine their roles in a library. conclusions and arguments in summary, compared to the client-server architecture and modular design of the traditional ils, the next-generation ils has an open architecture and is more flexible and unified in its workflow and interface, which will have a huge impact on library staffing models. the traditional ils specifies clear boundaries between staff modules and workflows while the next-generation ils has blurred these boundaries. the integration and enhancement of the functionality of the nextgeneration ils will help libraries streamline and automate workflows and processes for managing both print and electronic resources. it will increase libraries’ operational efficiency, reduce the information technology and libraries | september 2013 57 total cost of ownership, and improve services for users. particularly, it will free approximately 40 percent of library systems staff time from managing servers, software upgrades, client application upgrades, and data backups. moreover, the next-generation ils provides a new way for consortial libraries to collaborate, cooperate, and share resources. in addition, the web-scale services provided by the next-generation ils allow libraries to access an infrastructure and platforms that enable them to reach a broad, geographically diverse community while simultaneously focusing their services on meeting the specific needs of their end-users. thus the more integrated workflows and functionality allow library staff to work with more modules, play multiple roles, and back up each other, which will bring changes to traditional staffing models. however, the next-generation ils also brings libraries new challenges along with its clear advantages. librarians and library staff might have concerns pertaining to their job security and can be fearful of new technologies. they may feel anxious about how to reengineer their business processes, how to get training, how to improve their technological skills, and how to prepare for a transition. we argue here that library directors might think about these staff frustrations and find ways to address their concerns. libraries should provide staff more opportunities and training to help them to improve their knowledge and skills. redefining job descriptions and reorganizing library organizational structures might be necessary to better adapt to the changes brought about by the next-generation ils. systems staff might invest more time in local application developments, other digital initiatives, website maintenance, and other library priority projects. technical staff might reconsider their workflows and cross-train themselves to expand their knowledge and improve their work efficiency. they might spend more time on data quality control and special collection development or interact more with faculty on book and e-resource selections. we hope this analysis will provide some useful information and insights for those libraries planning to move to the next-generation ils. the shift will require academic libraries to reconsider their organizational structures and rethink their manpower distribution and staffing optimization to better focus on library priorities, projects, and services critical to their users. references 1. marshall breeding, “a cloudy forecast for libraries,” computers in libraries 31, no. 7 (2011): 32–34. 2. marshall breeding, “current and future trends in information

aspirations monica maceli and john j. burke information technology and libraries | december 2016 35 abstract information technology serves as an essential tool for today’s information professional, and ongoing research is needed to assess the technological directions of the field over time. this paper presents the results of a survey of the technologies used by library and information science practitioners, with attention to the combinations of technologies employed and the technology skills that practitioners wish to learn. the most common technologies employed were email, office productivity tools, web browsers, library catalogand database-searching tools, and printers, with programming topping the list of most-desired technology skill to learn. similar technology usage patterns were observed for early and later-career practitioners. findings also suggested the relative rarity of emerging technologies, such as the makerspace, in current practice. introduction over the past several decades, technology has rapidly moved from a specialized set of tools to an indispensable element of the library and information science (lis) workplace, and today it is woven throughout all aspects of librarianship and the information professions. information professionals engage with technology in traditional ways, such as working with integrated library systems, and in new innovative activities, such as mobile-app development or the creation of makerspaces.1 the vital role of technology has motivated a growing body of research literature, exploring the application of technology tools in the workplace, as well as within lis education, to effectively prepare tech-savvy practitioners. such work is instrumental to the progression of the field, and with the rapidly-changing technological landscape, requires ongoing attention from the research community. one of the most valuable perspectives in such research is that of the current practitioner. understanding current information professionals’ technology use can help in understanding the role and shape of the lis field, provide a baseline for related research efforts, and suggest future

https://doi.org/10.6017/ital.v35i4.9540 36 directions. the practitioner perspective is also valuable in separating the hype that often surrounds emerging technologies from the reality of their use and application within the lis field. this paper presents the results of a survey of lis practitioners, oriented toward understanding the participants’ current technology use and future technology aspirations. the guiding research questions for this work are as follows: 1. what combinations of technology skillsets do lis practitioners commonly use? 2. what combinations of technology skillsets do lis practitioners desire to learn? 3. what technology skillsets do newer lis practitioners use and desire to learn as compared to those with ten-plus years of experience in the field? literature review the growth and increasing diversity of technologies used in library settings has been matched by a desire to explore how these technologies impact expectations for lis practitioner skill sets. triumph and beile examined the academic library job market in 2011 by describing the required qualifications for 957 positions posted on the ala joblist and arl job announcements websites.2 the authors also compared their results with similar studies conducted in 1996 and 1988 to see if they could track changes in requirements over a twenty-three-year period. they found that the number of distinct job titles increased in each survey because of the addition of new technologies to the library work environment that require positions focused on handling them. the comparison also found that computer skills as a position requirement increased by 100 percent between 1988 and 2011, with 55 percent of 2011 announcements requiring them. looking more deeply at the technology requirements specifically, mathews and pardue conducted a content analysis of 620 jobs ads from the ala joblist to identify skills required in those positions.3 the top technology competencies required were web development, project management, systems development, systems applications, networking, and programming languages. they found a significant overlap of librarian skill sets with those of it professionals, particularly in the areas of web development, project management, and information systems. riley-huff and rholes found that the most commonly sought technology-related job titles were systems/automation librarian, digital librarian, emerging and instructional technology librarian, web services/development librarian, and electronic resources librarian.4 a few years later, maceli added to this list with newly popular technology-relating titles, including emerging technologies librarian, metadata librarian, and user experience/architect librarian.5 beyond examining which specific technologies librarians should be able to use, researchers have also pondered whether a list of skills is even possible to create. crawford synthesized a series of blog posts from various authors to discuss which technology skills are essential and which are too specialized to serve as minimum technology requirements for librarians.6 he questioned whether universal skill sets should be established given the variety of tasks within libraries and the unique backgrounds of each library worker. crawford also questioned the expectation that every librarian information technology and libraries | december 2016 37 will have a broad array of technology skills from programming to video editing to game design and device troubleshooting. partridge et al. reported on a series of focus groups held with 76 librarians that examined the skills required for members of the profession, especially those addressing technology.7 in the questions they asked the focus groups, the authors focused on the term “library 2.0” and attempted to gather suggestions on skills that current and future librarians need to assist users. they concluded that the groups identified that a change in attitudes by librarians was more important to future library service than the acquisition of skills with specific technology tools. importance was given to librarians’ abilities to stay aware of technological changes, be resilient and reflective in the face of them, and to communicate regularly and clearly with the members of their communities. another area examined in the studies is where the acquisition of technology skills should and does happen for librarians. riley-huff and rholes reported on a dual approach to measure librarians’ preparation for performing technology-related tasks.8 the authors assessed course offerings for lis programs to see if they included sufficient technology preparation for new graduates to succeed in the workplace. they then surveyed lis practitioners and administrators to learn how they acquired their skills and how difficult it is to find candidates with enough technology preparation for library positions. their findings suggest that while lis programs offer many technology courses, they lack standardization, and graduates of any program cannot be expected to have a broad education in library technologies. further research confirmed this troubling lack of consistency in technology-related curricula. singh and mehra assessed a variety of stakeholders, including students, employers, educators, and professional organizations, finding widespread concern about the coverage of technology topics in lis curricula.9 despite inconsistencies between individual programs, several studies provided a holistic view of the popular technology offerings within lis curricula. programs commonly offered one or more introductory technology courses, as well as courses in database design and development, web design and development, digital libraries, systems analysis, and metadata.10,11,12 as researchers have emphasized from a variety of perspectives, new graduates could not realistically be expected to know every technology with application to the field of information.13 there was widespread acknowledgement that learning in this area can, and must, continue in a lifelong fashion throughout one’s career. riley-huff and rholes reported that lis practitioners saw their own experiences involving continuing skill development on the job, both before and after taking on a technology role.14 however, literature going back many decades suggests that the increasing need for continuing education in information technology has generally not been matched by increasing organizational support for these ventures. numerous deterrents to continuing technology education were noted, including lack of time,15 organizational climate, and the perception of one’s age.16 while studies in this area have primarily focused on mls-level positions, jones reported on academic library support staff members and their perceptions of technology use over a ten-year period and found that increased technology responsibilities added technology skills in the workplace: information professionals’ current use and future aspirations | maceli and burke | https://doi.org/10.6017/ital.v35i4.9540 38 to workloads and increased workplace stress.17 respondents noted that increasing use of technology in their libraries has increased their individual workloads along with the range of responsibilities that they hold. method to build an understanding of the research questions stated above, which focus on the technologies currently used by information professionals and those they desired to learn, we designed and administered a thirteen-question anonymous survey (see appendix) to the subscribers of thirty library-focused electronic discussion groups between february 25 and march 13, 2015. the groups were chosen to target respondents employed in multiple types of libraries (academic, public, school, and special) with a wide array of roles in their libraries (public services librarians, systems staff members, catalogers, and so on). we solicited respondents with an email sent to the groups asking for their participation in the survey and with the promise to post initial results to the same groups. the survey included closed and open-ended questions oriented toward understanding current technology use and future aspirations as well as capturing demographics useful in interpreting and generalizing the results. the survey questions have been previously used and iteratively expanded over time by the second author, first in the fall of 2008, then spring of 2012, with summative results presented in the last three editions of the neal-schuman library technology companion. we obtained a total of 2,216 responses to the question, “which of the following technologies or technology skills are you expected to use in your job on a regular basis?” of these responses, 1,488 (67 percent) of the respondents answered the question regarding technologies they would like to learn: “what technology skill would you like to learn to help you do your job better?” we conducted basic reporting of response frequency for closed questions to assess and report the demographics of the respondents. to analyze the open-ended survey question results in greater depth, we conducted a textual analysis using the r statistical package (https://www.r-project.org/). we used the tm (text mining) package in r (http://cran.rproject.org/package=tm) to calculate frequency, correlation of terms, generate plots, and cluster terms. results the following section will first present an overview of survey responses and respondents, and then explore results as related to the stated four research questions. the lis practitioners who responded to the survey reported that their libraries are located in forty us states, eight canadian provinces, and forty-three other countries. academic libraries were the most common type of library represented, followed by public, school, special, and other (see table 1). information technology and libraries | december 2016 39 library type number of respondents percentage of all respondents academic 1,206 54.4 public 545 24.6 school 266 12 special 138 6.2 other 61 2.8 table 1. the types of libraries in which survey respondents work respondents also provided their highest level of education. a total of 77 percent of responding lis practitioners have earned a library-related or other master’s degrees, dual master’s degrees, or doctoral degrees. from these reported levels of education, it is likely that more respondents are in librarian positions than in library support staff positions. however, individuals with master’s degrees serve in various roles in library organizations, so the percentage of graduate degree holders may not map exactly to the percentage of individuals in positions that require those degrees. significantly fewer respondents (16 percent) reported holding a high school diploma, some college credit, an associate degree, or a bachelor’s degree as their highest level of education. another aspect we measured in the survey was tasks that respondents performed on a regular basis. the range of tasks provided in the survey allowed for a clearer analysis of job responsibilities than broad categories of library work such as “public services” or “technical services.” some respondents appeared to be employed in solo librarian environments where they are performing several roles. even respondents who might have more focused job titles such as “reference librarian” or “cataloger” may be performing tasks that overlap traditional roles and categories of library work. the tasks offered in the survey and the responses to each are shown in table 2. technology skills in the workplace: information professionals’

instruction, collection development, and circulation as the top four task areas, technical services-related activities are well represented; the next three in rank are cataloging, electronic resource management, and acquisitions. the overall list of tasks shows the diversity of work lis practitioners engage in, as each respondent chose an average of six tasks. the results also suggest that the survey respondents are well acquainted with a wide variety of library work rather than only having experience in a few areas, making their uses of technology more representative of the broader library world. the survey also questioned the barriers lis practitioners face as they try to add more technology to their libraries, and 2,161 respondents replied to the question, “which of the following are barriers to new technology adoption in your library?” financial considerations proved to be the most common barrier, with “budget” chosen by 80.7 percent of respondents, followed by “lack of staff time” (62.4 percent), “lack of staff with appropriate skill sets” (48.5 percent), and “administrative restrictions” (36.7 percent). information technology and libraries | december 2016 41 what combinations of technology skillsets do lis practitioners commonly use? responses from survey question 8, “which of the following technologies or technology skills are you expected to use in your job on a regular basis?,” were analyzed to build an understanding of this research questions. a total of 2,216 responses to this question were received. survey respondents were asked to select from a detailed list of technologies/skills (visible in question 8 of the appendix) that they regularly used. the top answers respondents chose for this question were: email, word processing, web browser, library catalog (public side), and library database searching. the full list of the top twenty-five technology skills and tools used is detailed in figure 1, with the list of the bottom fifteen technology skills used presented in figure 2. figure 1. top twenty-five technology skills/tools used by respondents (n = 2,216) 0 500 1,000 1,500 2,000 email word processing web browser library

frequent combinations of technology skills used in practice. first, a clustering approach was taken to visualize the most popular technologies that were commonly used in combination (figure 3). clustering helps in organizing and categorizing a large dataset when the categories are not known in advance, and, when plotted in a dendrogram chart, assists in visualizing these commonly co-occurring terms. the authors numbered the clusters identified in figure 3 for ease of reference. from left to right, the first cluster is focuses on communication and educational tools, the second emphasizes devices and software, the third contains web and multimedia creation tools, the fourth contains office productivity and public-facing information retrieval tools, and the fifth cluster has a diverse collection of responsibilities including systems-oriented responsibilities (from operating systems to specific hardware devices), working with ebooks, teaching with technology, and teaching technology to others. 0 500 1,000 1,500 2,000 mac os audio recording and editing technology equipment installation computer programming or coding assistive adaptive technology rfid chromebooks network

cluster analysis of most frequent technology skills used in practice, with red outlines on each numbered cluster notably, the list of top skills used (figure 1) falls more on the end-user side of technology; skills more oriented toward systems work (e.g. linux, server management, computer programming, or coding) were less frequently mentioned, and several were among the lowest reported (figure 2). of the 2,216 respondents, 15 percent used programming or coding skills regularly in their job (which is of interest as programming or coding was the skill most desired to learn by respondents; this will be discussed further in the context of the next research question). plotting the correlations between the more advanced technology skillsets can provide a picture of the work such systems-oriented positions are commonly responsible for, particularly as they are less well represented in the responses as a whole. figure 4 plots the correlated terms for those tasked with “server management.” it is fair to assume someone with such responsibilities falls on the highly technical end of the spectrum. technology skills in the workplace: information professionals’ current use and

and libraries | december 2016 47 we then explored the deeper context of responses and individually analyzed responses specific to the more popular technology desires. first, we assessed the responses mentioning the desire to learn coding or programming. of these responses, the most common specific technologies mentioned were html, python, css, javascript, ruby, and sql, listed in decreasing order of interest. although most participants did not describe what they would like to do with their desired coding or programming skills, of those that did, the responses indicated interest in ● becoming more empowered to solve their own technology problems (e.g., “i would like to learn the [programming languages] so i don't have to rely on others to help with our website,” “i’m one of the most tech-skilled people at my library, but i’d like to be able to build more of my own tools and manage systems without needing someone from it or outside support.”); ● improving communication with it (e.g., “how to speak code, to aid in communication with it,” “to better identify problems and work with it to fix them”); ● creating novel tools and improving system interoperability (e.g. “coding for app and api creation”); and ● bringing new technologies to their library and patrons (e.g., “coding so that i can incorporate a hackerspace in my library”). next, we took a clustering approach to visualize the terms commonly desired in combination. figure 8 describes the clustered terms that we found within the programming or coding responses. the terms “programming” and “coding” form a distinct cluster to the right of the diagram, indicating that many responses contained only those two terms. technology skills in the workplace: information professionals’ current use and future aspirations | maceli and burke | https://doi.org/10.6017/ital.v35i4.9540 48 figure 8. clustering of terms present in responses indicating the desire to learn coding or programming the remaining portion of the diagram begins to illustrate the specific technologies mentioned for those respondents that answered in greater detail or expanded on their general answer of programming or coding. other related desired technology-skill areas become apparent: database management, html and css (as well as the more general “web design,” which appeared in the top terms in table 3), php and javascript, python and sql, and xml creation, among others. the bulleted list presented in the previous paragraph illustrates some of the potential applications participants envisioned these skills being useful in, but the majority did not provide this level of detail in their response. editing was another prominent term that appeared across participant responses and was largely meant in the context of video editing. because of the vagueness of the term “editing,” a closer look was necessary to determine other technology desires. looking at terms highly correlated with “editing” revealed both video and photo editing to be important to respondents. several of the topappearing terms were used more generally: “database” and mobile “apps” were mentioned without specifying the technology tool or scenario of use, such that a more contextual analysis could not be conducted. these responses can be particularly difficult to interpret as the term “databases” can have a technical meaning (e.g., working with sql) or it can refer to the use of library databases from an end user perspective. information technology and libraries | december 2016 49 what technology skillsets do newer lis practitioners use and desire to learn as compared to those with ten-plus years experience in the field? of the 2,216 survey responses, 877 stated they had worked in libraries for ten or fewer years. we analyzed these responses separately from the remaining 1,334 respondents who had worked in libraries for more than ten years. of this group, 644 had worked in libraries for twenty-plus years (figure 9). a handful of participants did not answer the question and were omitted from the analysis. figure 9. number of survey responses falling into the various categories for number of years working in libraries the top technology skills used in the workplace did not differ significantly between the different groups. the top skills, as discussed earlier and presented in figure 1, were well represented and similarly ordered. a few small percentage points of difference were noted in a handful of the top skills (figure 10). those newer to the field were slightly more likely to teach others to use technology, use cloud-based storage, and use cloud-based productivity apps. more experienced practitioners regularly used the library management system (on the staff side) more than those that were newer to the field. 0 100 200 300 400 500 600 700 0-2 3-5 6-10 11-15 16-20 21+ technology skills in the workplace: information professionals’ current use and future aspirations |

mentioned, coding or programming, were mentioned by 28 percent of the respondents with zero to ten years’ experience, and by 15 percent of the respondents with eleven-plus years experience. there was slightly more interest (by a few percentage points) in databases, design, python, and ruby in the zero to ten years’ experience group. taking a closer look at the different year ranges in the zero to ten years of experience or less group, revealed that those with three to five years of experience were most likely to be interested in learning coding or programming skills. figure 11. percentage of respondents interested in learning coding or programming in the groups with ten or fewer years’ experience of the participants that answered the question at all, several stated that there were no technology skills they would need or like to learn for their position, either because they were comfortable with their existing skills or were simply open to learning more as needed (but nothing specific came to mind). combined with those who did not answer the question (and so presumably did not have a particular technology they were interested in learning), 28 percent of the zero to ten years’ experience group and 31 percent of the eleven-plus years experience group did not have any technologies that they desired to learn at the moment. discussion as detailed earlier, the most common technologies employed by lis practitioners were email, office productivity tools, web browsers, library catalog and database searching tools, and printers. generally similar technology usage patterns were observed for early and later-career practitioners and programming topped the list of most-desired technology skill to learn. 0% 5% 10% 15% 20% 25% 30% 35% 0-2 years 3-5 years 6-10 years technology skills in the workplace: information professionals’ current use and future aspirations | maceli and burke | https://doi.org/10.6017/ital.v35i4.9540 52 the cluster analysis presented in figure 3 suggests that a relatively small percentage of practitioners have technology-intensive roles that would require skills such as programming, working with databases, systems administration, etc. rather, the cluster analysis showed common technology skillsets focused on the end-user side of technology tools. in fact, most of the top ten skills used—email, office productivity tools (word processing, spreadsheets and presentation software), web browsers, library catalog and database searching, printers, and teaching others to use technology—are fairly nontechnical in nature. a potential exception is that of teaching technology. figure 6 suggests that teaching others to use technology entails several hardware devices (for example, laptops, tablets, smartphones, and scanners) as well as online and digital resources, such as ebooks. however, most of the popular skills used would be considered baseline skills for information workers in any domain. as suggested by tennant, programming and other advanced technical skills do not necessarily need to be a core skill for all information professionals, but knowledge of the potential applications and possibilities of such tools is required.19 this idea was echoed by partridge et al., whose findings emphasized the need for awareness and resilience in tackling new technological developments.20 these skills alone would obviously be too little for lis practitioners explicitly seeking a high-tech role, as discussed in maceli.21 however, further research directed toward exploring the mental models and general technological understanding of information professionals would be helpful in understanding the true level of practitioner engagement with technology, to complement the list of relatively low-tech tools employed. programming has been a skill of great interest within the information professions for many years and the respondents’ enthusiasm and desire to learn in this area was readily apparent from the survey results, with nearly 20 percent of participants citing either “programming” or “coding” as a skill they desired to learn. in the context of their current responsibilities, 15 percent of respondents overall mentioned “computer programming or coding” as a regular technological skill they employed (figure 2). there was a slight difference between the librarians with fewer than eleven years of experience—19 percent coded regularly—compared to 13 percent of those with eleven or more years of experience. within the years-of-experience divisions, the newer practitioners were more interested in learning programming, with the peak of interest at three to five years in the workplace (figure 11). the relatively low interest or need to learn programming in the newest practitioners potentially indicates a hopeful finding—that their degree program was sufficient preparation for the early years of their career. prior research would contradict this finding. for example, choi and rasmussen’s 2006 survey found that, in the workplace, librarians frequently felt unprepared in their knowledge of programming and scripting languages.22 in the intervening years, curriculum has shifted to more heavily emphasize technology skills, including web development and other topics covering programming,23 perhaps better preparing early career practitioners. overall, information technology and libraries | december 2016 53 programming remains a popular skill in continuing education opportunities as well as in job listings,24 which aligns well with the respondents’ strong interest in this area. the skills commonly co-occurring with programming in practice included working with linux, database software, managing servers, and webpage creation (figure 4). taken as a whole, these skills indicate job responsibilities falling toward the systems side, with webpage creation a skill that bridged intensely technical and more user-focused work (as also evident in figure 4).this indicates that, though programming may be perceived as highly desirable for communicating and extending systems, as a formal job responsibility it may still fall to a relatively small number of information professionals in any significant manner. makerspace technologies and their implementation possibilities within libraries have garnered a great deal of excitement and interest in recent years, with much literature highlighting innovative projects in this area (such as american library association25 and bagley26). fourie and meyer provided an overview of the existing makerspace literature, finding that most research efforts focus on the needs and construction of the physical space.27 given the general popularity of the topic (as detailed in moorefield-lang),28 it is interesting to note that such technologies were infrequently mentioned by survey participants, both in those desiring to learn these tools and those who were currently using them. the most infrequent skills used (figure 2) included makerspace technologies, 3d printers, augmented, and virtual reality. only a small number of respondents currently used this mix of makerspace-oriented and emerging technologies, and only 3 percent of respondents mentioned interest in learning makespace-related skills. despite many research efforts exploring the particulars of unique makerspaces in a case-study approach (for example, moorefield-lang),29 little data exists on the total number of makerspaces within libraries, and the skillset is largely absent from prior research describing lis curriculum and job listings. this makes it difficult to determine whether the low number of participants that reported working with makerspace technologies is reflective of the small number of such spaces in existence or simply that few practitioners are assigned to work in this area, no matter their popularity. in either case, these findings provide a useful baseline with which to track the growth of makerspace offerings over time and librarian involvement in such intensely technological work. despite the interest and clear willingness to learn and use technology, several workplace challenges became apparent from participant responses. as prior research explored (notable riley-huff and rholes),30 practitioners assumed they would be continually learning and building skills on the job throughout their career to stay current technologically. as described in the earlier results section, many participants mentioned that, although they were highly willing and able to learn, the necessary organizational resources were lacking. as one participant noted, “i’d like to learn anything but the biggest problem seems to be budget (time and monetary).” several participants expressed feeling overwhelmed with their current workload. new learning opportunities, technological or otherwise, were simply not feasible. although the survey results indicated that practitioners of all ages were roughly equally interested in learning new technology skills in the workplace: information professionals’ current use and future aspirations | maceli and burke | https://doi.org/10.6017/ital.v35i4.9540 54 technologies, a handful of responses mentioned that ageist issues were creating barriers. though few, these respondents described being dismissed as technologists because of their age. these themes have long been noted in the large body of continuing-education-related literature going back several decades. stone’s study ranked lack of time as the top deterrent to professional development for librarians, and it appears little has changed.31 chan and auster noted that organizational climate and the perception of one’s age may impair the pursuit of professional development, among other impediments.32 however, research has noted a generally strong drive in older librarians to continue their education; long and applegate found a preference in latercareer librarians for learning outlets provided by formal library schools and related professional organizations, but a lower interest in generally popular topics such as programming.33 these findings were consistent with the participant responses gathered in this survey. finally, as detailed in the results section, a significant percent of respondents (33 percent) did not answer the question regarding what technologies they would like to learn. as is a limitation with survey research, it is difficult to know what the respondent’s intention was in not answering the question, i.e., are they comfortable with their current technology skills? do they lack the time or interest in pursuing further technology education? and of those that did answer, many did not specify their intended use of the technologies they desired to learn. so a deeper exploration of what technologies lis practitioners desire to learn and why would be of value as well. these questions are worth pursuing in more depth through further research efforts. conclusion this study provides a broad view into the technologies that lis practitioners currently use and desire to learn, across a variety of types of libraries, through an analysis of survey responses. despite a marked enthusiasm toward using and learning technology, respondents described serious organizational limitations impairing their ability to grow in these areas. the lis practitioners surveyed have interested patrons, see technology as part of their mission, and are not satisfied with the current state of affairs, but they seem to lack money, time, skills, and a willing library administration. though respondents expressed a great deal of interest in more advanced technology topics, such as programming, the majority typically engaged with technology on an end-user level, with a minority engaged in deeply technical work. this study suggests future work in exploring information professionals’ conceptual understanding of and attitudes toward technology, and a deeper look at the reasoning behind those who did not express a desire to learn new technologies. information technology and libraries | december 2016 55 references

researcher, state scientific and technical library of ukraine. © 2020. abstract the gradual transition to a digital economy requires all business entities to adapt to the new environmental conditions that are taking place through their digital transformation. these tasks are especially relevant for scientific libraries, as digital technologies make changes in the main subject field of their activities, the processes of creating, storing, and information disseminating. in order to find directions for the transformation of scientific libraries and determine their role in the digital economy, a study of the features of digital transformation and the experience of the digital transformation of foreign libraries was conducted. management of research data, which is implemented through the creation of current research information systems (cris) was found to be one of the most promising areas of the digital transformation of libraries. the problem area of this direction and ways of engaging libraries in it have been also analyzed in the work. introduction the transition to a digital economy contributes to the even greater penetration of digital technologies into our lives and the emergence of new conditions of competition and trends in organizations’ development. big data, machine learning, and artificial intelligence are becoming common tools implemented by the pioneers of digital transformation in their activities.1 significant changes in the main functions of libraries, storage and dissemination of information caused by the development of digital technologies, affect the operational activities of libraries, user and partners’ requests to the library, and ways to meet them. in the process of adapting to these changes, the role of libraries in the digital economy is changing. this study is designed to find current areas of library development and to determine the role of the library in the digital economy. achieving this goal requires study of the “digital economy” concept and the peculiarities of the digital transformation of organizations in order to better understand the role of the library in it; research on the development of libraries and determine what best fits the new role of the library in the digital economy; identification of obstacles to the development of this area and ways to engage libraries in it. the concept of the “digital economy” the transition to an information society and digital economy will gradually change all industries, and all companies must change accordingly.2 taking advantage of the digital economy is the main driving force of innovation, competitiveness, and economic development of the country.3 the transition to a digital economy is not instant but occurs over many years. the topic emerged starting at the end of the twentieth century, but in recent years has experienced rapid growth. in the web of science (wos) citation database, publications with this term in the title began to be published in 1996 (figure 1). mailto:serhii.zharinov@gmail.com information technology and libraries december 2020 the role of the library in the digital economy | zharinov 2 figure 1. the number of publications in the wos citation database for the query “digital economy.” one of the first books devoted entirely to the study of the digital economy concept is the work of don tapscott, published in 1996. in this book, the author understands the digital economy as an economy in which the use of digital computing technologies in economic activity becomes its dominant component.4 thomas mesenbourg, an american statistician and economist, identified in 2000 the three main components of the digital economy: e-business, e-commerce, and e-business infrastructure.5 a number of works on the development of indicators to assess the state of the digital economy, in particular, the work of philip barbet and nathalie coutinet, are based on the analysis of these components.6 alnoor bhimani, in his 2003 paper, “digitization and accounting change,” defined the digital economy as “the digital interrelationships and dependencies between emerging communication and information technologies, data transfers along predefined channels and emerging platforms, and related contingencies within and across institutional and organizational entities.”7 bo carlsson’s 2004 article described the digital economy as a dynamic state of the economy characterized by the constant emergence of new activities based on the use of the internet and new forms of communication between different authors of ideas, whose communication allows them to generate new activities.8 in 2009, john hand gave the meaning of the digital economy as the new design or use of information and communication technologies that help transform the lives of people, society, or business.9 0 100 200 300 400 500 600 700 1995 2000 2005 2010 2015 2020 information technology and libraries december 2020 the role of the library in the digital economy | zharinov 3 ciocoiu carmen nadia, in her 2011 article, explained the digital economy as a state of the economy where knowledge and networking begin to play a more important role than capital in a postindustrial society due to technology.10 in a 2014 article, kit lesya defined the digital economy as an element of the network economy, characterized by the transformation of all spheres of the economy by transferring information resources and knowledge to a computer platform for further use.11 ukrainian scientists mykhailo voinarenko and larysa skorobohata, in a study of network tools in 2015, gave the following definition of the digital economy: “the digital economy, unlike the internet economy, assumes that all economic processes (except for the production of goods) take place independently of the real world. goods and services do not have a physical medium but are ‘electronic.’”12 yurii pivovarov, director of the ukrainian association for innovation development (uaid), gives the following definition: “digital economy is any activity related to information technology. and in this case, it is important to separate the terms: digital economy and it sphere. after all, it is not about the development of it companies, but about the consumption of services or goods they provide—online commerce, e-government, etc.—using digital information technology.”13 taking into account the above, in this study, the digital economy is defined as digital infrastructure encompasses all business entities and their activities. the transition to the digital economy is the process of creating conditions for the digital transformation of organizations, the creation of digital infrastructure, and the process of gradual involvement of various economic entities and certain sectors of the economy in the digital infrastructure. one of the first practical and political manifestations of the transition to the digital economy was the european commission’s index of digital economy and society (desi), first published in 2014. the main components of the index are communications, human capital, internet use, digital integration, and digital public services. among european countries in 2019, there is significant progress in the digitalization of business and in the interaction of society with the state.14 for ukraine, the first step towards the digital economy was the digital economy and development concept of ukraine, which defines the understanding of the digital economy, the direction and principles of transition to it.15 thus, for active representatives of the public sector, this concept is a signal that the development of structures and organizations should be based not on improving operational efficiency, but on transformation in accordance with the requirements of industry 4.0. confirmation of the seriousness of the ukrainian government’s intentions in this direction is the creation of the ministry of digital transformation in 2019 and the digitization of the latest public services through online services.16 one of the priority challenges which needs to be solved at the stage of transition to the digital economy is the development of skills in working with digital technologies in the entire population . this is relevant not only for ukraine, but also for the european union. in europe, a third of the active workforce does not have basic skills in working with digital technologies; in ukraine, 15.1 percent of ukrainians do not have digital skills, and the share of the working population with below-average digital skills is 37.9 percent.17 information technology and libraries december 2020 the role of the library in the digital economy | zharinov 4 part of the solution to this challenge in ukraine is entrusted to the “digital education” project, implemented by the ministry of digital transformation (osvita.diia.gov.ua), which through the mini-series created by him for different target audiences should form digital literacy in the population of ukraine. features of digital transformation developed digital skills in the population make the digital transformation of organizations not just a competitive advantage, but a prerequisite for their survival. thus, the larger the target audience is accustomed to the benefits of the digital economy, the more actively the organization is to adapt to new requirements and customer needs, to the new competitive environment. digital transformation of the organization is a complex process that is not limited to the implementation of software in the company’s activities or automation of certain components of production. it includes changes to all elements of the company, including methods of manufacturing and customer service, the organization’s strategy and business model, approaches , and management methods. according to a study by mckinsey, the integration of new technologies into a company's operations can reduce profits in 45 percent of cases.18 therefore, it is extremely important to have a comprehensive approach to digital transformation, understanding the changes being implemented, choosing the method of their implementation, and gradually involving all structural units and business processes in the process of transformation. the boston consulting group study identified six factors necessary for the effective use of the benefits of modern technologies:19 • connectivity of analytical data; • integration of technologies and automation; • analysis of results and application of conclusions; • strategic partnership; • competent specialists in all departments; and • flexible structure and culture. mckinsey consultants draw attention to the low percentage of successful digital transformation practices and based on the successful experience of 83 companies form five categories of recommendations that can contribute to successful digitalization:20 • involvement of leaders experienced in digitalization; • development of digital staff skills; • creating conditions for the use of digital skills by staff; • digitization of tools and working procedures of the company; and • establishing digital communication and ensuring the availability of information. experts at the institute of digital transformation identify four main stages of digital transformation in the company:21 1. research, analysis and understanding of customer experience. 2. involvement of the team in the process of digital transformation and implementation of corporate culture, which contributes to this process. 3. building an effective operating model based on modern systems. 4. transformation of the business model of the organization. https://osvita.diia.gov.ua/ information technology and libraries december 2020 the role of the library in the digital economy | zharinov 5 the “integrated model of digital transformation” study identifies one of the key factors of successful digital transformation, focusing on priority digital projects, the development and implementation of which should be engaged in specific organizational teams. the authors identify three main functional activities for digital transformation teams, the implementation of which provides a gradual comprehensive renewal of the company, namely: the creation and implementation of digital strategy, digital activity management, digitization of operational activities.22 in their study, ukrainian scientists natalia kraus, oleksandr holoborodko, and kateryna kraus determine that the general pattern for all digital economy projects is their focus on a specific consumer and comprehensive use of available information about the latter and the conditions of project effectiveness.23 initially, the project is pre-tested on a small scale, and only after obtaining satisfactory results from the testing of new principles of activity in a narrow target audience is the project scaled to a wider range of potential users. all this reduces the risks associated with digital transformation. eliminating unnecessary changes and false hypotheses on a small scale allows to avoid overspending at the stage of a comprehensive transformation of the entire enterprise. therefore, the process of effective digital transformation should begin with the involvement of experienced leaders in the field of digital transformation, analysis of the weaknesses of the organization, and building of a plan for its comprehensive transformation, which is divided into individual projects implemented by individual qualified teams with a gradual increase in the volume of these projects, while confirming their effectiveness on a small scale. the process of digital transformation should be accompanied by constant training of employees in digital skills. the goal of digital transformation is to build an efficient, high-profile company that can quickly adapt to new environmental conditions, which is achieved through the introduction of digital technologies and new methods and tools of organization management. directions of library development in the digital economy based on the study of the digital economy concept and the peculiarities of digital transformation, the review of library development in the digital economy was conducted to find the library’s place in digital infrastructure and potential projects that can be implemented on a separate library as part of its comprehensive transformation plan. the main task is to determine the new role of the library in the digital economy and the areas that best meet it. the search for directions in the development of the library in response to the spread of digital technology began at the end of the last century. one of the first concepts to reflect the impact of the internet on the library sector is the concept of the digital library, published in 1999.24 in 2006, the concept of “library 2.0” emerged, which is based on the use of web 2.0 technologies, dynamic sites, users become data authors, open-source software, api interfaces, data added to one database is immediately fed to partner databases.25 the spread of the use of social networks, mobile technologies, and their successful use in library practice has led to the formation of the concept of “library 3.0.”26 the development of open source, cloud service, big data, augmented reality, context-aware, and other technologies has influenced library activities, which is reflected in the “library 4.0.”27 researchers, scholars, and the professional community continued to develop the concepts of the modern library, drawing on the experience of implementing changes in library activities and taking into account the development of other areas, and in 2020 articles began to appear which described the concept of “library 5.0,” based on a personalized approach to students, information technology and libraries december 2020 the role of the library in the digital economy | zharinov 6 support of each student during the whole period of study, development of skills necessary for learning and a set of other supporting actions integrated into the educational process.28 in determining the current role of the library in the digital economy, it is necessary to pay attention to a study by denis solovianenko, who in identifies research and educational infrastructure as one of the key elements of scientific libraries of the twenty-first century.29 olga stepanenko considers libraries as part of the information and communication infrastructure, the development of which is one of the main tasks of the transformation of the socioeconomic environment in accordance with the needs of the digital economy, which ensures high efficiency of stakeholders the pace of digitalization of the state economy, which occurs through the development of its constituent elements.30 the importance of traditional library services replacing digital infrastructure, based on the example of the moravian library, is proved in a study by michal indrak and lenka pokorna, published in april 2020.31 projects that contribute to the library’s adaptation to the conditions of the digital economy, implemented in the environment of public libraries, include: digitization of library collections (including historical heritage) and the creation of a database of full-text documents; providing free access to the internet via library computers and wi-fi; organization of online customer service, development of services that do not require a physical presence in the library; organization of events for the development of digital skills of users, work with information.32 under such conditions, the role of the librarian as a specialist in the field of information changes from being a custodian to being an intermediary, a distributor.33 one of the main objectives of library activity in the digital economy becomes overcoming a digital divide, dissemination of knowledge about modern technologies and innovations, the assistance of their use by the community, development of digital skills in all users of the library.34 an example of the digital public library is the digital north library project in canada, which resulted in the creation of the inuvialuit digital library (https://inuvialuitdigitallibrary.ca). the project lasted four years, bringing together researchers from different universities and the community in the region, who together digitized cultural heritage documents and created metadata. the library now has more than 5,200 digital resources collected in 49 catalogues. the implementation of this project provides access to library services and information to a significant number of people living in remote areas of northern canada and unable to visit libraries (https://sites.google.com/ualberta.ca/dln/home?authuser=0, https://inuvialuitdigitallibrary.ca).35 other representatives of modern digital libraries, one of the main tasks of which is the preservation of cultural heritage and the spread of national culture, are the british library (https://www.bl.uk), the hispanic digital library—biblioteca nacional de españa (http://www.bne.es), gallica digital library in france (https://gallica.bnf.fr), the german digital library—deutsche digitale bibliothek (https://www.deutsche-digitale-bibliothek.de), and the european library (https://www.europeana.eu). another direction was the development of analytical skills in information retrieval. academic libraries, operating with their competencies in information retrieval and information technology, which refined the results of the analysis were able to better identify trends in academia and expand cooperation with teachers to update their curricula.36 libraries become active participants

https://www.deutsche-digitale-bibliothek.de/ https://www.europeana.eu/ information technology and libraries december 2020 the role of the library in the digital economy | zharinov 7 in the process of teaching, learning, and assessment of acquired knowledge in educational institutions. t. o. kolesnikova, in her research of models of library development, substantiates the expediency of creating information intelligence centers for the implementation of the latest scientific advances in training and production processes, the involvement of libraries in the activities of higher educational establishments in the educational process, and the creation of centralized repositories as directions of development for university libraries of ukraine.37 one of the advantages of the development and dissemination of digital technologies is the possibility of forming individual curricula for students. involvement of university libraries in this area is one of the new areas of their activities in the digital economy.38 one of the important areas of operation for departmental and scientific-technical libraries that contribute to increasing the innovative potential of the country is activity in the area of intellectual property. consulting services in the field of intellectual property, information support for scientists, creation of electronic patent information databases in the public domain , and other related services are important components of libraries in many countries. consulting services in the field of intellectual property, information support for scientists, creation of electronic patentinformation databases in the public domain and other related services are important components of libraries in many countries.39 another important component of libraries’ transformation is the deepening of their role in scientific communication; expanding the boundaries of the use of information technology in order to integrate scientific information into a single network; creation and management of information technology infrastructure of science.40 the presence of libraries on social networks has become an important component of their digital transformation. on the one hand, libraries have thus created another source of information dissemination and expanded the number of service delivery channels, for the implementation of which they have developed online training videos and interactive help services.41 on the other hand, social networks have become a marketing tool to engage the audience in the digital fund of the library and its online services. an additional important component of the presence of libraries in social networks was the establishment of contacts and exchange of ideas with other professional organizations, which contributed to the further expansion of the network of library partners.42 another area of activity that libraries take on in the digital economy is the management of research data, which is confirmed by the significant number of publications on this topic in professional scientific and research journals for 2017–18.43 joining this area allows libraries to become part of the scientific digital information and communication infrastructure, the creation of which is one of the main tasks of digital transformation on the way to the digital economy.44 the development of this area contributes to the digitalization of scientific and information sphere, systematization and structuring of all scientific research data has a positive effect on the effectiveness of research, the level of scientific novelty of the results of intellectual activity. the ukrainian institute of the future with the digital agency of ukraine consider digital transformation as the integration of modern digital technologies into all spheres of business. the introduction of modern technologies (artificial intelligence, blockchain, koboty, digital twins, iiot platforms and others) in the production process will lead to the transition to industry 4.0. according to their forecasts, the key competence in industry 4.0 should be data processing and information technology and libraries december 2020 the role of the library in the digital economy | zharinov 8 analytics.45 research information is an integral part of this competence, so the development of this area is one of the most promising for the library in the digital economy. the tools used in the management of research data are called current research information systems, abbreviated as cris. in ukraine, there is no such system connected to the international community. 46 the change of the library’s role from a repository to its manager, the alignment of the functions and tasks of a cris with the key requirements of the digital economy, and the advantages of such systems, together with the fact that they are still not used in ukraine, make this area extremely relevant for research and a promising area of work of scientific libraries, so we’ll consider it more thoroughly. problems in research data management the global experience of research information management shows several problems in the process of research data management. some of them are related to the processes of workflow organization, control, and reporting. this is due to the use of several poorly coordinated systems to organize the work of scientists. data sets from different systems without metadata are very difficult to combine into a single system, and it is almost impossible to automate the process. all this is manifested in the lack of information security of the decision-making process in the field of science, both at the state level and at the level of individual structures. this situation can lead to wrong management decisions and can lead to overspending on similar, duplicate projects; increasing the cost of the process of recruiting and finding scientists with relevant experience for research, finding the equipment needed for research. cris, which began to appear in europe in the 1990s, are designed to overcome these shortcomings and promote the effective organization of scientific work. such systems are now widespread throughout the world, with a total of about five hundred, which are mainly concentrated in europe and india. however, there is currently no research information management system in ukraine that meets international standards and integrates with international scientific databases. this omission slows down ukraine’s integration into the international scientific community. the solution to this problem may be the creation of the national electronic scientific information system uris (ukrainian research information system).47 the development of this system is an initiative of the ministry of education and science of ukraine. it is based on combining data from ukrainian scientific institutions with data from crossref and other organizations, as well as ensuring integration with other international cris systems through the use of the cerif standard. future developers of the system face a number of challenges, both specific and already studied by foreign scientists. a significant number of studies in this area are designed to over come the problem of lack of access to research data, as well as to solve problems of data standardization and openness. in the global experience, the directions of collection processes management and development of structured data sets, their distribution on a commercial basis, and also ways of receiving the advantage of providing them in open access are investigated. the mechanisms of financing these processes are studied, in particular, the effective ways of attracting patronage funds are analyzed. the possibilities of licensing the received data sets and their distribution, approaches and tools that can be the most effective for the library are determined. in particular, alice wise describes information technology and libraries december 2020 the role of the library in the digital economy | zharinov 9 the experience of settling some legal aspects by clarifying the use of the site in the license agreement, which covers the conditions of access to information and search in it, while maintaining a certain level of anonymity.48 the problem of data consistency is related to the lack of uniform standards for information retention, which would relate to the format of the data, the metadata itself, the methods of their generation and use. thus, the use of different standards and formats in repositories and archives leads to problems with data consistency in researchers, which, in turn, affects the quality of service delivery and makes it impossible to use multiple data sets.49 another important problem for the dissemination of research data is the lack of tools, components in libraries, and repositories of higher educational establishments and scientific institutions. it is worth to develop the infrastructure so that at the end of the projects, in addition to the research results, the scientists publish the research data they used and generated. this approach will be convenient both for authors (in case they need to reuse the research data) and for other scientists (because they will have access to data that can be used in their own research).50 the development of the necessary tools is quite relevant, especially because researcher-practitioners are in favor of sharing the data they create with other researchers and the licensed use of other people’s datasets in conducting their own research, according to international surveys.51 another reason for the low prevalence of research data is that datasets have less of an impact on a researcher’s reputation and rating than publications.52 this is partly due to the lack of citation tracking infrastructure in datasets, in contrast to the publication of research results, and the lack of standards for storing and publishing data. prestigious scientific journals have been struggling with this problem for several years. for example, the american economic review requires authors whose articles contain empirical work, modelling, or experimental work to provide information about research data in a volume enough for replication.53 nature and science require authors to preserve research data and provide them at the request of the editors of the journals.54 one of the reasons for the underdeveloped infrastructure in research data management is the weak policy of disseminating free access to this data, as a result of which even a small part of usable scientific data remains closed by license agreements and cannot be used by other scientists.55 open science initiatives related to publications have been operating in the scientific field for a long time, but their dissemination to research data remains insufficient. the development of the uris system will provide management of scientific information, will solve problems highlighted in the above scientific works of researchers; will promote the efficient use of funds, will simplify the process of finding data for conducting research; will discipline research , and therefore will have a positive impact on the entire economy of ukraine. library and research information management library involvement in the development process for scientific information management systems will be an important future direction of their work. such systems, which could include all the necessary information about scientific research, will contribute to the renewal and development of the library sphere of ukraine, will promote the transition of the state to a digital economy. information technology and libraries december 2020 the role of the library in the digital economy | zharinov 10 the creation of the uris system is designed to provide access to research data generated by both ukrainian and foreign scientists. such a system can ensure the development of cooperation in the field of research, intensification of knowledge exchange, and interaction through the open exchange of scientific data and integration of ukrainian scientific infrastructure into the world scientific and information space. according to surveys conducted by the international organizations eurocris and oclc, of the 172 respondents working in the field of research information management, 83 percent said that libraries play an important role in the development of open science, copyright, and the deposit of research results. the share of libraries that play a major role in this direction was 90 percent. almost 68 percent of respondents noted the significant contribution of libraries in filling in the metadata needed to correctly identify the work of researchers in various databases; 60 percent noted the important role of libraries in verifying the correctness of metadata filling by researchers, and almost 49 percent of respondents assess the role of libraries as the main one in the management of research data (figure 4). figure 4. the proportion of organizations among 172 users of cris-systems that assess the role of libraries in the management of research information as basic or supporting.56 at the same time, the activity of libraries in the direction of assistance in information management of scientific research can take various forms, which should be adopted by scientific libraries of ukraine; some of these forms will be useful to public libraries that can become science ambassadors in their communities. based on the experience of foreign libraries, we have identified areas of activity in which the library can join the management of research information. 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% financial support for rim project management maintaining or servicing technical operations impact assessment and reporting strategic development, management and planning creating internal reports for departments system configuration outreach and communication initiating rim adaption research data management metadata validation workflows metadata entry training and support open access, copyright and deposit information technology and libraries december 2020 the role of the library in the digital economy | zharinov 11 one of the main directions for libraries that cooperate with cris users or are themselves the organizers of such systems is the introduction and support of open science. historically, libraries support open science because they provide access to scientific papers, but they can further expand their activities. using open data resources and promoting them among the scientific community, involving scientific users in disseminating their own research results on the principles of open science, supporting users in disseminating their publications, creating conditions for increasing the citation of scientific papers, tracking information about user publications, creating and support of public profiles of scientists in scientific and professional resources and scientific social networks—all this will help to intensify researchers in engaging in open science and take advantages of this area. the analysis of the world experience shows that in the activity of scientific libraries there is a significant intensification of support for the strategic goals of the structures that finance their activities and to which they are subordinated. libraries are moving away from the usual customer service and expanding their activities through the use of their own assets and the introduction of new modern tools. such libraries try to promote the development of parent structures, increase modern competencies to meet the needs and goals of these institutions better. by introducing and implementing various tools for the development of management, libraries synchronize their strategy with the strategy of the parent structure to achieve a synergistic effect. the next important direction of library development is their socialization. wanting to get rid of the antiquated understanding of the word library, many of them conduct campaigns aimed at changing the image of the library in the imagination of users, communities, and society. an important component of this system step is to build relationships with the target audience, creating user communities around the library, which are not only its users but also supporters, friends, and promoters. building relationships with members of the scientific community allows libraries to reduce resistance to change as a result of the introduction of scientific information management systems; to influence users positively so that they introduce new tools into their usual activities, receive benefits, and become an active part of the scientific space structuring process. recently, work with metadata has undergone some changes. the need for identification and structuring of data in the world scientific space leads to the fact that they are already filled not only by libraries but also by other organizations that produce, issued, publish scientific results and scientific literature. scientists are beginning to make more active use of modern standards in the field of information in order to promote their own work. libraries, in turn, take on the role of consultant or contractor with many years of experience working with metadata and sufficient knowledge in this area. on the other hand, filling in metadata by users frees up the time of librarians and creates conditions for them to perform other functions, such as information management, creation of automated data collection and management systems integrated with scientific databases—both ukrainian and international. another area of research information management is the direct management of this process. thus, cris are developed and implemented with the contribution of scientific libraries in different countries of the world. this allows libraries to combine disparate data obtained from different sources, compile scientific reports, evaluate the effectiveness of scientific activities of the institution, create profiles of scientific institutions and scientists, develop research network s, etc. information technology and libraries december 2020 the role of the library in the digital economy | zharinov 12 scientists and students can find the results of scientific research, and look for partners and sources of funding for research. research managers have access to up-to-date scientific information, which allows to more accurately assess the productivity and influence of individual scientists, research groups and institutions. business representatives get access to up-to-date information on promising scientific developments, and the public—a way to control research conducting effectively. conclusions ukraine is on the path to a digital economy, characterized by the penetration of new technologies in all areas of human activity, simplification of access to information, goods and services, blurring the geographical boundaries of companies, increasing the share of automated and robotic production units, strengthening the role of creation and use databases. these changes affect all sectors of the economy, and all organizations, without exception, need to adapt accordingly. rapid response to relevant changes helps to increase competitiveness both at the level of individual organizations and at the level of the state economy. adaptation to the conditions of the digital economy occurs through digital transformation—a complex process that requires a review of all business processes of the organization and radically changes its business model. the digital transformation of the organization takes place through the involvement of management, which is competent in digitization, updating management methods, developing digital skills, establishing efficient production and services, implementing digital to ols and building digital communication, implementing individual development projects, and adapting to new user needs. the digital transformation of the economy occurs through the transformation of its individual sectors, creating conditions for the transformation of their representatives. one of the first steps in the process of transition to the digital economy is the establishment of digital information and communication infrastructure. libraries are representatives of the information sphere, which were the main operators of information in the analogue era. significant changes in the subject area of their activities require the search for a new role for libraries. modern projects and directions of library development are integral elements of transformation to the conditions of the digital economy. the result of completing this complex implementation will allow libraries to update their management methods, the range of services, and the channels of their provision; change fixed assets through their digitization, structuring the data and creating metadata; affect approaches to communication with users and cooperation with both domestic and international partners; change the functions and positioning of the library; and will enable them become effective information operator-managers. in the digital economy, the role of the library is changing from passively collecting and storing information to actively managing it. one of the areas of development that most comprehensively meets this role is the management of research data, which is implemented through the creation of cris systems. thus, the main asset of libraries is a digital, structured database, which is automatically and regularly updated, the main focus of which is to support the decision-making process. the library becomes an assistant in conducting research, finding funding, partners, fixed assets and information; a partner in the strategic management of both scientific organizations and the state at the level of committees and ministries. information technology and libraries december 2020 the role of the library in the digital economy | zharinov 13 the development of this area in ukraine requires solving a number of technical, administrative, and managerial questions that are relevant not only in ukraine, but also around the world. in particular, libraries need to address the issue of data integration and consistency, its accessibility and openness, copyright, and personal data issues. solving the problems of creation and operation of cris systems in ukraine are promising areas for future research. endnotes 1 andriy dobrynin, konstantin chernykh, vasyl kupriyanovsky, pavlo kupriyanovsky and serhiy sinyagov, “tsifrovaya

research data management library and research information management conclusions endnotes 2 information technology and libraries | march 2009 andrew k. pace president’s message: lita now andrew k. pace (pacea@oclc.org) is lita president 2008/2009 and executive director, networked library services at oclc inc. in dublin, ohio. a t the time of this writing, my term as lita president is half over; by the time of publication, i will be in the home stretch—a phrase that, to me, always connotes relief and satisfaction that is never truly realized. i hope that this time between ala conferences is a time of reflection for the lita board, committees, interest groups, and the membership at large. various strategic planning sessions are, i hope, leading us down a path of renewal and regeneration of the division. of course, the world around us will have its effect—in particular, a political and economic effect. first, the politics. i was asked recently to give my opinion about where the new administration should focus its attention regarding library technology. i had very little time to think of a pithy answer to this question, so i answered with my gut that the united states needs to continue its investment in it infrastructure so that we are on par with other industrialized nations while also lending its aid to countries that are lagging behind. furthermore, i thought it an apt time to redress issues of data privacy and retention. the latter is often far from our minds in a world more connected, increasingly through wireless technology, and with a user base that, as one privacy expert put it, would happily trade a dna sample for an extra value meal. i will resist the urge to write at greater length a treatise on the bill of rights and its status in 2008. i will hope, however, that lita’s technology and access and legislation and regulation committees will feel reinvigorated post–election and post–inauguration to look carefully at the issues of it policy. our penchant for new tools should always be guided and tempered by the implementation and support of policies that rationalize their use. as for the economy, it is our new backdrop. one anecdotal view of this is the number of e-mails i’ve received from committee appointees apologizing that they will not be able to attend ala conferences as planned because of the economic downturn and local cuts to library budgets. libraries themselves are in a paradoxical situation—increasing demand for the free services that libraries offer while simultaneously facing massive budget cuts that support the very collections and programs people are demanding. what can we do? well, i would suggest that we look at library technology through a lens of efficiency and cost savings, not just from a perspective of what is cool or trendy. when it comes to running systems, we need to keep our focus on end-user satisfaction while considering total cost of ownership. and if i may be selfish for a moment, i hope that we will not abandon our professional networks and volunteer activities. while we all make sacrifices of time, money, and talent to support our profession, it is often tempting when economic times are hard to isolate ourselves from the professional networks that sustain us in times of plenty. politics and economics? though i often enjoy being cynical, i also try to make lemonade from lemons whenever i can. i think there are opportunities for libraries to get their own economic bailout in supporting public works and emphasizing our role in contributing to the public good. we should turn our “woe-are-we” tendencies that decry budget cuts and low salaries into championed stories of “what libraries have done for you lately.” and we should go back to the roots of it, no matter how mythical or anachronistic, and think about what we can do technically to improve systemwide efficiencies. i encourage the membership to stay involved and reengage, whether through direct participation in lita activities or through a closer following of the activities in the ala office of information technology policy (oitp, www.ala.org/ala/aboutala/offices/oitp) and the ala washington office itself. there is much to follow in the world that affects our profession, and so many are doing the heavy lifting for us. all we need to do sometimes is pay attention. make fun of me if you want for stealing a campaign phrase from richard nixon, but i kept coming back to it in my head. in short, library information technology— now more than ever. letter from the editor: reviewers wanted letter from the editor reviewers wanted kenneth j. varnum information technology and libraries | march 2021 https://doi.org/10.6017/ital.v40i1.13xxx together with one of the other journals published by ala’s core division, information technology and libraries (ital) and library leadership and management (ll&m) invite applications for peer reviewers. serving as a reviewer is a great opportunity for individuals from all types of libraries and with a wide variety of experience to contribute to scholarship within our chosen profession. we are seeking the broadest pool of reviewers possible. reviewer responsibilities for both journals are to have an interest/experience with the journal’s topics, as described below. reviewers should expect to review 2-4 articles a year and should provide thoughtful and actionable comments to authors and the editor. reviewers will work with the editor, associate editor, and/or editorial board of the corresponding journal. see the job description for ital reviewers for more details about this new role. we welcome applications from individuals at libraries of all types, levels of experience, locations, perspectives, and voices, especially those from underrepresented groups. reviewers will be selected to maximize the diversity of representation across these areas, so if you’re not sure if you should apply, please do! increasing the pool of reviewers for information technology and libraries is part of the editorial board’s desire to provide equitable treatment to submitted articles and will enable us to follow a more typical process for peer-reviewed journals: a two-reviewer double-blind process. that will be a welcome and, frankly, overdue change to ital’s current process, in which submitted articles are typically reviewed by one person. expanding the number of reviewers across the breadth of subject areas our journal covers will foster a more rigorous yet more open review process. should you be more interested more in the policy side of this journal, please watch out for a call for volunteers for the ital editorial board. that process will start in april. * * * * * * * as this issue of the journal goes online, covid as a global health crisis has just entered its second year. i’m constantly reminded of the duality of our collective ability to show resilience and exhibit fragility as we continue to endure this period. when i wrote the letter from the editor a year ago, i focused on the imminent vote to establish a new ala division, core, as the most important question facing me. how quickly things changed! by the time the march 2020 issue was published, everything was different. wherever you are, however you have adapted to the situation, i hope you are well and, like me, are turning from wondering when this period will end, to wondering what “normal” will be in the post-pandemic world. kenneth j. varnum, editor varnum@umich.edu march 2021

president leadership, infrastructure, futures christopher cronin information technology and libraries | december 2020 https://doi.org/10.6017/ital.v39i4.13027 christopher cronin (cjc2260@columbia.edu) is core president and associate university librarian for collections, columbia university. © 2020. i am so pleased to be able to welcome all ital subscribers to core: leadership, infrastructure, futures! this issue marks the first of ital since the election of core’s inaugural leadership. a merger of what was formerly three separate ala divisions—the association of library collections & technical services (alcts), library & information technology association (lita), and the library leadership & management association (llama)—core is an experiment of sorts. it is, in fact, multiple experiments in unification, in collaboration, in compromise, in survival. while initially born out of a sheer fight or flight response to financial imperatives and the need for organizational effectiveness, developing core as a concept and as a model for an enduring professional association very quickly became the real motivation for those of us deeply embedded in its planning. core is very deliberately not an all-caps acronym representing a single subset of practitioner within the library profession. it is instead an assertion of our collective position at the center of our profession. it is a place where all those working in libraries, archives, museums, historical societies—information and cultural heritage broadly—will find reward and value in membership and a professional home. all organizations need effective leaders, strong infrastructure, and a vision for the future. and that is what core strives to build with and for its members. while i welcome ital’s readers into core, i also welcome core’s membership into ital. no longer publications of their former divisions, all three journals within core have an opportunity to reconsider their mandates. as with all things, audience matters. ital’s readership has now expanded dramatically, and those new readers must be invited into ital’s world just as much as ital has been invited into theirs. as we embark on this first year of the new division, we do so with a sense of altogether newness more than of a mere refresh, and a sense of still becoming more than a sense of having always been. and who doesn’t want to reinvent themselves every once in a while? start over. move away from the bits that aren’t working so well, prop up those other bits that we know deserve more, and venture into some previously uncharted territory. how will being part of this effort, and of an expanded division, reframe ital’s mandate? the importance of information technology has never been more apparent. it is not lost on me that we do this work in core during a year of unprecedented tumult. in 2020, a murderous global pandemic was met with unrelenting political strife, pervasive distribution of misinformation and untruths, devastating weather disasters, record-setting unemployment, heightened attention on an array of omnipresent social justice issues, and a racial reckoning that demands we look both inward and outward for real change. individually and collectively, we grieve so many losses —loss of life, loss of income, loss of savings, loss of homes, loss of dignity, loss of certainty, loss of control, loss of physical contact. and throughout all of these challenges, what have we relied on more this year than technology? technology kept us productive and engaged. it provided a focal point for communication and connection. it provided venues for advocacy, expression, inspiration, and, as a mailto:cjc2260@columbia.edu information technology and libraries december 2020 leadership, infrastructure, futures | cronin 2 counterpoint to that pervasive distribution of misinformation, it provided mechanisms to amplify the voices of the oppressed and marginalized. for some, but unfortunately not all, technology also kept us employed. and as the physical doors of our organizations closed, technology provided us with new ways to invite our users in, to continue to meet their information needs, and to exceed all of our expectations for what was possible even with closed physical doors. and yet our reliance on and celebration of technology in this moment has also placed another critical spotlight on the devastating impact of digital poverty on those who continue to lack access, and by extension also a spotlight on our privilege. in her parting words to you in the final issue of ital as a lita journal, evviva weinraub lajoie, the last president of lita, wrote: we may have always known that inequities existed, that the system was structured to make sure that some folks were never able to get access to the better goods and services, but for many, this pandemic is the first time we have had those systemic inequities held up to our noses and been asked, “what are you going to do to change this?” balancing those priorities will require us to lean on our professional networks and organizations to be more and to do more. i believe that together, we can make core stand up to that challenge. i believe we will do this, too, and with a spirit of reinvention that is guided by principles and values that don’t just inspire membership but also improve our professional lives and experience in tangible ways. it was a privilege to have served as the final president of alcts and such a humbling and daunting responsibility to now transition into serving as core’s first. it is a responsibility i do not take lightly, particularly in this moment when so much is demanded of us. as we strive for equity and inclusion, we do so knowing that we are only as

research agenda jody condit fagan an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 7 7 abstract academic web search engines have become central to scholarly research. while the fitness of google scholar for research purposes has been examined repeatedly, microsoft academic and google books have not received much attention. recent studies have much to tell us about google scholar’s coverage of the sciences and its utility for evaluating researcher impact. but other aspects have been understudied, such as coverage of the arts and humanities, books, and non-western, non-english publications. user research has also tapered off. a small number of articles hint at the opportunity for librarians to become expert advisors concerning scholarly communication made possible or enhanced by these platforms. this article seeks to summarize research concerning google scholar, google books, and microsoft academic from the past three years with a mind to informing practice and setting a research agenda. selected literature from earlier time periods is included to illuminate key findings and to help shape the proposed research agenda, especially in understudied areas. introduction recent pew internet surveys indicate an overwhelming majority of american adults see themselves as lifelong learners who like to “gather as much information as [they] can” when they encounter something unfamiliar (horrigan 2016). although significant barriers to access remain, the open access movement and search engine giants have made full text more available than ever.1 the general public may not begin with an academic search engine, but google may direct them to google scholar or google books. within academia, students and faculty rely heavily on academic web search engines (especially google scholar) for research; among academic researchers in high-income areas, academic search engines recently surpassed abstracts & indexes as a starting place for research (inger and gardner 2016, 85, fig. 4). given these trends, academic librarians have a professional obligation to understand the role of academic web search engines as part of the research process. jody condit fagan (faganjc@jmu.edu) is professor and director of technology, james madison university, harrisonburg, va. 1 khabsa and giles estimate “almost 1 in 4 of web accessible scholarly documents are freely and publicly available” (2014, 5). an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 8 two recent events also point to the need for a review of research. legal decisions in 2016 confirmed google’s right to make copies of books for its index without paying or even obtaining permission from copyright holders, solidifying the company’s opportunity to shape the online experience with respect to books. meanwhile, microsoft rebooted their academic web search engine, now called microsoft academic. at the same time, information scientists, librarians, and other academics conducted research into the performance and utility of academic web search engines. this article seeks to review the last three years of research concerning academic web search engines, make recommendations related to the practice of librarianship, and propose a research agenda. methodology a literature review was conducted to find articles, conference presentations, and books about the use or utility of google books, google scholar, and microsoft academic for scholarly use, including comparisons with other search tools. because of the pace of technological change, the focus was on recent studies (2014 through 2016, inclusive). a search was conducted on “google books” in ebsco’s library and information science and technology abstracts (lista) on december 19, 2016, limited to 2014-2016. of the 46 results found, most were related to legal activity. only four items related to the tool’s use for research. these four titles were entered into google scholar to look for citing references, but no additional relevant citations were found. in the relevant articles found, the literature reviews testified to the general lack of studies of google books as a research tool (abrizah and thelwall 2014; weiss 2016) with a few exceptions concerning early reviews of metadata, scanning, and coverage problems (weiss 2016). a search on “google books” in combination with “evaluation or review or comparison” was also submitted to jmu’s discovery service,2 limited to 2014-2016 in combination with the terms. forty-nine items were found and from these, three relevant citations were added; these were also entered into google scholar to look for citing references. however, no additional relevant citations were found. thus, a total of seven citations from 2014-2016 were found with relevant information concerning google books. earlier citations from the articles’ bibliographies were also reviewed when research was based on previous work, and to inform the development of a fuller research agenda. a search on “microsoft academic” in lista on february 3, 2017 netted fourteen citations from 2014-2016. only seven seemed to focus on evaluation of the tool for research purposes. a search on “microsoft academic” in combination with terms “evaluation or review or comparison” was also submitted to jmu’s discovery service, limited to 2014-2016. eighteen items were found but no additional citations were added, either because they had already been found or were not relevant. the seven titles found in lista were searched in google scholar for citing references; four additional relevant citations were found, plus a paper relevant to google scholar not 2 jmu’s version of ebsco discovery service contained 453,754,281 items at the time of writing and is carefully vetted to contain items of curricular relevance to the jmu community (fagan and gaines 2016). information technology and libraries | june 2017 9 previously discovered (weideman 2015). thus, a total of eleven citations were found with relevant information for this review concerning microsoft academic. because of this small number, several articles prior to 2014 were included in this review for historical context. an initial search was performed on “google scholar” in lista on november 19, 2016, limited to 2014-2016. this netted 159 results, of which 24 items were relevant. a search on “google scholar” in combination with terms “evaluation or review or comparison” was also submitted to jmu’s discovery tool limited to 2014-2016, and eleven relevant citations were added. items older than 2014 that were repeatedly cited or that formed the basis of recent research were retrieved for historical context. finally, relevant articles were submitted to google scholar, which netted an additional 41 relevant citations. altogether, 70 citations were found to articles with relevant information for this review concerning google scholar in 2014-2016. readers interested in literature reviews covering google scholar studies prior to 2014 are directed to (gray et al. 2012; erb and sica 2015; harzing and alakangas 2016b). findings google books google books (https://books.google.com) contains about 30 million books, approaching the library of congress’s 37 million, but far shy of google’s estimate of 130 million books in existence (wu 2015), which google intends to continue indexing (jackson 2010). content in google books includes publisher-supplied, self-published, and author-supplied content (harper 2016) as well as the results of the famous google books library project. started in december 2004 as the “google print” project,3 the project involved over 40 libraries digitizing works from their collections, with google indexing and performing ocr to make them available in google books (weiss 2016; mays 2015). scholars have noted many errors with google books metadata, including misspellings, inaccurate dates, and inaccurate subject classifications (harper 2016; weiss 2016). google does not release information about the database’s coverage, including which books are indexed or which libraries’ collections are included (abrizah and thelwall 2014). researchers have suggested the database covers mostly u.s. and english-language books (abrizah and thelwall 2014; weiss 2016). the conveniences of google books include limits by the type of book availability (e.g. free ebooks vs. google e-books), document type, and date. the detail view of a book allows magnification, hyperlinked tables of contents, buying and “find in a library” options, “my library,” and user history (whitmer 2015). google books also offers textbook rental (harper 2016) and limited print-on-demand services for out-of-print books (mays 2015; boumenot 2015). in april 2016, the supreme court affirmed google’s right to make copies for its index without paying or even obtaining permission from copyright holders (authors guild 2016; los angeles times 2016). scanning of library books and “snippet view” was deemed fair use: “the purpose of the copying is highly transformative, the public display of text is limited, and the revelations do 3 https://www.google.com/googlebooks/about/history.html an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 10 not provide a significant market substitute for the protected aspects of the originals” (u.s. court of appeals for the second circuit 2015). literature concerning high-level implications of google books suggests the tool is having a profound effect on research and scholarship. the tool has been credited for serving as “a huge laboratory” for indexing, interpretation, working with document image repositories, and other activities (jones 2010). at the same time, the academic community has expressed concerns about google books’s effects on social justice and how its full-text search capability may change the very nature of discovery (hoffmann 2014; hoffmann 2016; szpiech 2014). one study found that books are far more prevalently cited in wikipedia than are research articles (kousha and thelwall 2017). yet investigations of google books’ coverage and utility as a research tool seem to be sorely lacking. as weiss noted, “no critical studies seem to exist on the effect that google books might have on the contemporary reference experience” (weiss 2016, 293). furthermore, no information was found concerning how many users are taking advantage of google books; the tool was noticeably absent from surveys such as (inger and gardner's (2016) and from research centers such as the pew internet research project. in a largely descriptive review, harper (2016) bemoaned google books’ lack of integration with link resolvers and discovery tools, and judged it lacking in relevant material for the health sciences, because so much of the content is older. she also noted the majority of books scanned are in english, which could skew scholarship. the non-english skew of google books was also lamented by weiss, who noted an “underrepresentation of spanish and overestimation of french and german (or even japanese for that matter)” especially as compared to the number of spanish speakers in the united states (weiss 2016, 286-306). whitmer (2015) and mays (2015) provided practical information about how google books can be used as a reference tool. whitmer presented major google books features and challenged librarians to teach google books during library instruction. mays conducted a cursory search on the 1871 chicago fire and described the primary documents she retrieved as “pure gold,” including records of city council meetings, notes from insurance companies, reports from relief societies, church sermons on the fire, and personal memoirs (mays 2015, 22). mays also described google books as a godsend to genealogists for finding local records (e.g. police departments, labor unions, public schools). in her experience, the geographic regions surrounding the forty participating google books library project libraries are “better represented than other areas” (mays 2015, 25). mays concludes, “its poor indexing and search capabilities are overshadowed by the ease of its fulltext search capabilities and the wonderful ephemera that enriches its holdings far beyond mere ‘books’” (mays 2015, 26). abrizah and thelwall (2014) investigated whether google books and google scholar provided “good impact data for books published in non-western countries.” they used a comprehensive list of arts, humanities, and social sciences books (n=1,357) from the five main university presses in information technology and libraries | june 2017 11 malaysia 1961-2013. they found only 23% of the books were cited in google books4 and 37% in google scholar (p. 2502). the overlap was small: only 15% were cited in both google scholar and google books. english-language books were more likely to be cited in google books; 40% of english language books were cited versus 16% malay. examining the top 20 books cited in google books, researchers found them to be mostly written in english (95% in google books vs 29% in the sample), and published by university of malaysia press (60% in google books vs 26% in the sample) (2505). the authors concluded that due to the low overlap between google scholar and google books, searching both engines was required to find the most citations to academic books. kousha and thelwall (2015; 2011) compared google books with thomson reuters book citation index (bkci) to examine its suitability for scholarly impact assessment and found google books to have a clear advantage over bkci in the total number of citations found within the arts and humanities, but not for the social sciences or sciences. they advised combining results from bkci with google books when performing research impact assessment for the arts and humanities and social sciences, but not using google books for the sciences, “because of the lower regard for books among scientists and the lower proportion of google books citations compared to bkci citations for science and medicine” (kousha and thelwall 2015, 317). microsoft academic microsoft academic (https://academic.microsoft.com) is an entirely new software product as of 2016. therefore, the studies cited prior to 2016 refer to entirely different search engines than the one currently available. however, a historical account of the tool and reviewers’ opinions was deemed helpful for informing a fuller picture of academic web search engines and pointing to a research agenda. microsoft academic was born as windows live academic in 2006 (carlson 2006), was renamed live search academic after a first year of struggle (jacsó 2008), and was scrapped two years later after the company recognized it did not have sufficient development support in the united states (jacsó 2011). microsoft asia research group launched a beta tool called libra in 2009, which redirected to the “microsoft academic search” service by 2011. early reviews of the 2011 edition of microsoft academic search were promising, although the tool clearly lacked the quantity of data searched by google scholar (jacsó 2011; hands 2012). there were a few studies involving microsoft academic search in 2014. ortega and aguillo (2014) compared microsoft academic search and google scholar citations for research evaluation and concluded “microsoft academic search is better for disciplinary studies than for analyses at institutional and individual levels. on the other hand, google scholar citations is a good tool for individual assessment because it draws on a wider variety of documents and citations” (1155). 4 google books does not support citation searching; the researchers searched for the book title to manually find citations to a book. an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 12 as part of a comparative investigation of an automatic method for citation snowballing using microsoft academic search, choong et al. (2014) manually searched for a sample of 949 citations to journal or conference articles cited from 20 systematic reviews. they found microsoft academic search contained 78% of the cited articles and noted its utility for testing automated methods due to its free api and no blocks to automated access. the researchers also tested their method against google scholar, but noted “computer-access restrictions prevented a robust comparison” (n.p.). also in 2014, orduna-malea et al. (2014) attempted a longitudinal study of disciplines, journals, and organizations in microsoft academic search only to find the database had not been updated since 2013. furthermore they found the indexing to be incomplete and still in process, meaning microsoft academic search’s presentation of information about any particular publication, organization, or author was distorted. despite this finding, mas was included in two studies of scholar profiles. ortega (2015) compared scholar profiles across google scholar, microsoft academic search, research gate, academia.edu, and mendeley, and found little overlap across the sites. they also found social and usage indicators did not consistently correlate with bibliometric indicators, except on the researchgate platform. social and usage indicators were “influenced by their own social sites,” while bibliometric indicators seemed more stable across all services (13). ward et al. (2015) still included microsoft academic search in their discussion of scholarly profiles as part of the social media network, noting microsoft academic search was painfully time-consuming to work with in terms of consolidating data, correcting items, and adding missing items. in september 2016, hug et al. demonstrated the utility of the new microsoft academic api by conducting a comparative evaluation of normalized data from microsoft academic and scopus (hug, ochsner, and braendle 2016). they noted microsoft academic has “grown massively from 83 million publication records in 2015 to 140 million in 2016” (10). the microsoft academic api offers rich, structured metadata with the exception of document type. they found all attributes containing text were normalized and that identifiers were available for all entities, including references, supporting bibliometricians’ needs for data retrieval, handling, and processing. in addition to the lack of document type, the researchers also found the “fields of study” to be too granular and dynamic, and their hierarchies incoherent. they also desired the ability to use the doi to build api requests. nevertheless, the advantages of microsoft academic’s metadata and api retrieval suggested to hug et al. that microsoft academic was superior to google scholar for calculating research impact indicators and bibliometrics in general. in october 2016, harzing and alakangas compared publication and citation coverage of the new microsoft academic with google scholar, scopus, and web of science using a sample of 145 academics at the university of melbourne (harzing and alakangas 2016a) including observations from 20-40 faculty each in the humanities, social sciences, engineering, sciences, and life sciences. they discovered microsoft academic had improved substantially since their previous study (harzing 2016b), increasing 9.6% for a comparison sample in comparison with 1.4%, 2%, and 1.7% growth in google scholar, scopus, and web of science (n.p.). the researchers noted a few information technology and libraries | june 2017 13 problems with data quality, “although the microsoft academic team have indicated they are working on a resolution” (n.p.). on average, the researchers found that microsoft academic found 59% as many citations as google scholar, 97% as many citations as scopus, and 108% as many citations as web of science. google scholar had the top counts for each disciplinary area, followed by scopus except in the social sciences and humanities, where microsoft academic ranked second. the researchers explained that microsoft academic “only includes citation records if it can validate both citing and cited papers as credible,” as established through a machine-learningbased system, and discussed an emerging metric of “estimated citation count” also provided by microsoft academic. the researchers concluded that microsoft academic is promising to be “an excellent alternative for citation analysis” and suggested microsoft should work to improve coverage of books and grey literature. google scholar google scholar was released in beta form in november 2004, and was expanded to include judicial case law in 2009. while google scholar has received much attention in academia, it seems to be regarded by google as a niche product: in 2011 google removed scholar from the list of top services and list of “more” services, relegating it to the “even more” list. in 2014, the scholar team consisted of just nine people (levy 2014). describing google scholar in an introductory manner is not helped by google’s vague documentation, which simply says it “includes scholarly articles from a wide variety of sources in all fields of research, all languages, all countries, and over all time periods.”5 the “wide variety of sources” includes “journal papers, conference papers, technical reports, or their drafts, dissertations, pre-prints, post-prints, or abstracts,” as well as court opinions and patents, but not “news or magazine articles, book reviews, and editorials.” books and dissertations uploaded to google book search are “automatically” included in scholar. google says abstracts are key, noting “sites that show login pages, error pages, or bare bibliographic data without abstracts will not be considered for inclusion and may be removed from google scholar.” studies of google scholar can be divided in to three major categories of focus: investigating the coverage of google scholar; the use and utility of google scholar as part of the research process; and google scholar’s utility for bibliographic measurement, including evaluating the productivity of individual researchers and the impact of journals. there is some overlap across these categories, because studies of google scholar seem to involve three questions: 1) what is being searched? 2) how does the search function? and 3) to what extent can the user usefully accomplish her task? the coverage of google scholar scholars want to know what “scholarship” is covered by google scholar, but the documentation merely states that it indexes “papers, not journals”6 and challenges researchers to investigate 5 https://scholar.google.com/intl/en/scholar/inclusion.html 6 https://www.google.com/intl/en/scholar/help.html#coverage an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 14 google scholar’s coverage empirically despite google scholar’s notoriously challenging technical limitations. while some limitations of google scholar have been corrected over the years, longstanding logistical hurdles involved with studying google scholar’s coverage have been well-documented for over a decade (shultz 2007; bonato 2016; haddaway et al. 2015; levay et al. 2016), and include: • search queries are limited to 256 characters • not being able to retrieve more than 1,000 results • not being able to display more than 20 results per page • not being able to download batches of results (e.g. to load into citation management software) • duplicate citations (beyond the multiple article “versions”), requiring manual screening • retrieving different results with advanced and basic searches • no designation of the format of items (e.g. conference papers) • minimal sort options for results • basic boolean operators only7 • illogical interpretation of boolean operators: esophagus or oesophagus and oesophagus or esophagus return different numbers of results (boeker, vach, and motschall 2013) • non-disclosure of the algorithm by which search results are sorted. additionally, one study reported experiencing an automated block to the researcher’s ip address after the export of approximately 180 citations or 180 individual searches (haddaway et al. 2015, 14). furthermore, the research excellence framework was unable to use google scholar to assess the quality of research in uk higher education institutions, because of researchers’ inability to agree with google on a “suitable process for bulk access to their citation information, due to arrangements that google scholar have in place with publishers” (research excellence framework 2013, 1562). such barriers can limit what can be studied and also cost researchers significant time in terms of downloading (prins et al. 2016) and cleaning citations (levay et al. 2016). despite these hurdles, research activity analyzing the coverage of google scholar has continued in the past two years, often building off previous studies. this section will first discuss google scholar’s size and ranking, followed by its coverage of articles and citations, then its coverage of books, grey literature, and open access and institutional repositories. google scholar size and ranking in a 2014 study, khabsa and giles estimated there were at least 114 million english-language scholarly documents on the web, of which google scholar had “nearly 100 million.” another study by orduna-malea, ayllón, martín-martín, and lópez-cózar (2015) estimated that the total number 7 e.g., no nesting of logical subexpressions deeper than one level (boeker, vach, and motschall 2013) and no truncation operators. information technology and libraries | june 2017 15 of documents indexed by google scholar, without any language restriction, was between 160 and 165 million. by comparison, in 2016 the author’s discovery tool contained about 168 million items in academic journals, conference materials, dissertations, and reviews.8 google scholar’s presence in the information marketplace has influenced vendors to increase the discoverability of their content, including pushing for the display of abstracts and/or the first page of articles (levy 2014). proquest and gale indexes were added to google scholar in 2015 (quint 2016). martín-martín et al. (2016b) noted that google scholar’s agreements with big publishers come at a price: “the impossibility of offering an api,” which would support bibliometricians’ research (54). google scholar’s results ranking “aims to rank documents the way researchers do, weighing the full text of each document, where it was published, who it was written by, as well as how often and how recently it has been cited in other scholarly literature.”9 martín-martín and his colleagues (2017, 159) conducted a large, longitudinal study of null query results in google scholar and found a strong correlation between result list ranking and times cited. the influence of citations is so strong that when the researchers performed the same search process four months later, 14.7% of documents were missing in the second sample, causing them to conclude even a change of one or two citations could lead to a document being excluded or included from the top 1,000 results (157). using citation counts as a major part of the ranking algorithm has been hypothesized to produce the “matthew effect,” where “work that is already influential becomes even more widely known by virtue of being the first hit from a google scholar search, whereas possibly meritorious but obscure academic work is buried at the bottom” (antell et al. 2013, 281). google scholar has been shown to heavily bias its ranking toward english-language publications even when there are highly cited non-english publications in the result set, although selection of interface language may influence the ranking. martin-martin and his colleagues noted that google scholar seems to use the domain of the document’s hosting web site as a proxy for language, meaning that “some documents written in english but with their primary version hosted in nonanglophone countries’ web domains do appear in lower positions in spite of receiving a large number of citations” (martin-martin et al. 2017, 161). this effect is shown dramatically in figure 3 of their paper. google scholar coverage: articles and citations the coverage of articles, journals, and citations by google scholar has been commonly examined by using brute force methods to retrieve a sample of items from google scholar and possibly one or more of its competitors. (studies discussed in this section are listed in table 1). the goal is usually to determine how well google scholar’s database compares to traditional research databases, usually in a specific field. core methodology involves importing citations into software such as publish or perish (harzing 2016a), cleaning the data, then performing statistical tests, 8 the discovery tool does not contain all available metadata but has been carefully vetted (fagan and gaines 2016). 9 https://www.google.com/intl/en/scholar/about.html an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 16 expert review, or both. haddaway (2015) and moed et al. (2016) have written articles specifically discussing methodological aspects. recent studies repeatedly find that google scholar’s coverage meets or exceeds that of other search tools, no matter what is identified by target samples, including journals, articles, and citations (karlsson 2014; harzing 2014; harzing 2016b; harzing and alakangas 2016b; moed, barilan, and halevi 2016; prins et al. 2016; wildgaard 2015; ciccone and vickery 2015). in only three studies did google scholar find fewer items, and the meaningful difference was minimal.10 science disciplines were the most studied in google scholar, including agriculture, astronomy, chemistry, computer science, ecology, environmental science, fisheries, geosciences, mathematics, medicine, molecular biology, oceanography, physics, and public health. social sciences studied include education (prins et al. 2016), economics (harzing 2014), geography (ştirbu et al. 2015, 322-329), information science (winter, zadpoor, and dodou 2014; harzing 2016b), and psychology (pitol and de groote 2014). studies related to the arts or humanities 2014-2016 included an analysis of open access journals in music (testa 2016) and a comparison between google scholar and web of science for research evaluation within education, pedagogical sciences, and anthropology11 (prins et al. 2016). wildgaard (2015) and bornmann et al. (2016) included samples of humanities scholars as part of bibliometric studies, but did not discuss disciplinary aspects related to coverage. prior to 2014, the only study found related to the arts and humanities compared google scholar with historical abstracts (kirkwood jr. and kirkwood 2011). google scholar’s coverage has been growing over time (meier and conkling 2008; harzing 2014; winter, zadpoor, and dodou 2014; bartol and mackiewicz-talarczyk 2015, 531; orduña-malea and delgado lópez-cózar 2014) with recent increases in older articles (winter, zadpoor, and dodou 2014; harzing and alakangas 2016b), leading some to question whether this supports the documented trend of increased citation of older literature (martín-martín et al. 2016c; varshney 2012). winter et al. noted that in 2005 web of science yielded more citations than google scholar for about two-thirds of their sample, but for the same sample in 2013, google scholar found more citations than web of science, with only 6.8% of citations not retrieved by google scholar (winter, zadpoor, and dodou 2014, 1560). the unique citations of web of science were “typically documents before the digital age and conference proceedings not available online” (winter, zadpoor, and dodou 2014, 1560). harzing and alakangas’s (2016b) large-scale longitudinal comparison of google scholar, scopus, and web of science suggested that google scholar’s retroactive expansion has stabilized and now all three databases are growing at similar rates. 10 for example, bramer, giustini, and kramer (2016a) found slightly more of their 4,795 references from systematic reviews in embase (97.5%) than in google scholar (97.2%). in testa (2016), the music database rilm indexed two more of the 84 oa journals than google scholar (which indexed at least one article from 93% of the journals). finally, in a study using citations to the most-cited article of all time as a sample, web of science found more citations than did google scholar (winter, zadpoor, and dodou 2014). 11 prins et al. classified anthropology as part of the humanities. information technology and libraries | june 2017 17 google scholar also seems to cover both the oldest and the most recent publications. unlike traditional abstracts and indexes, google scholar is not limited by starting year, so as publishers post tables of contents of their earliest journals online, google scholar discovers those sources (antell et al. 2013, 281). trapp (2016) reported the number of citations to a highly-cited physics paper after the first 11 days of publication to be 67 in web of science, 72 in scopus, and 462 in google scholar (trapp 2016, 4). in a study of 800 citations to nobelists in multiple fields, harzing found that “google scholar could effectively be 9–12 months ahead of web of science in terms of publication and citation coverage” (2013, 1073). an increasing proportion of journal articles in google scholar are freely available in full text. a large-scale, longitudinal study of highly-cited articles 1950-2013 found 40% of article citations in the sample were freely available in full text (martín-martín et al. 2014). another large-sample study found 61% of articles in their sample from 2004–2014 could be freely accessed (jamali and nabavi 2015). in both studies, nih.gov and researchgate were the top two full-text providers. google scholar’s coverage of major publisher content varies; having some coverage of a publisher does not imply all articles or journals from that publisher are covered. in a sample of 222 citations compared across google scholar, scopus, and web of science, google scholar contained all of the springer titles, as many elsevier titles as scopus, and the most articles by wolters kluwer and john wiley. however, among the three databases, google scholar contained the fewest articles by bmj and nature (rothfus et al. 2016). an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 18 18 study sample results (bartol and mackiewicztalarczyk 2015) documents retrieved in response to searches on crops and fibers in article titles, 1994-2013 (samples varied by crop) google scholar returned more documents retrieved for each crop. for example, “hemp” retrieved 644 results in google scholar, 493 in scopus, and 318 in web of science; google scholar demonstrated higher yearly growth of records over time. (bramer, giustini, and kramer 2016b) references from a pool of systematic reviewer searches in medicine (n=4795) google found 97.2%, embase, 97.5%, medline 92.3% of all references; when using search strategies, embase retrieved 81.6%, medline 72.6%, and google scholar 72.8%. (ciccone and vickery 2015) based on 183 user searches randomly selected from ncsu libraries’ 2013 summon search logs (n=137) no significant difference between the performance of google scholar, summon, and eds for known-item searches; “google scholar outperformed both discovery services for topical searches.” (harzing 2014) publications and citation metrics for 20 nobelists in chemistry, economics, medicine, physics, 20122013 (samples varied) google scholar coverage is now “increasing at a stable rate” and provides “comprehensive coverage across a wide set of disciplines for articles published in the last four decades” (575). (harzing 2016b) citations from one researcher (n=126) microsoft academic found all books and journal articles covered by google scholar; google scholar found 35 additional publications including book chapters, white papers, and conference papers. (harzing and alakangas 2016a) samples from (harzing and alakangas 2016b, 802) (samples varied by faculty) google scholar provided higher “true” citation counts than microsoft academic but microsoft academic “estimated” citation counts were 12% higher than google scholar for life sciences and equivalent for the sciences. information technology and libraries | june 2017 19 (harzing and alakangas 2016b) citations of the works of 145 faculty among 37 scholarly disciplines at the university of melbourne (samples varied by faculty) for the top faculty member, google scholar had 519 total papers (compared with 309 in both web of science and scopus); google scholar had 16,507 citations (compared with 11,287 in web of science and 11,740 in scopus). (hilbert et al. 2015) documents published by 76 information scientists in german-speaking countries (n=1,017) google scholar covered 63%, scopus, 31%, bibsonomy, 24%, mendeley, 19%, web of science, 15%, citeulike, 8%. (jamali and nabavi 2015) items published between 2004 and 2014 (n=8,310) 61% of articles were freely available; of these, 81% were publisher versions and 14% were pre-prints; researchgate was the top full-text source netting 10.5% of full-text sources, followed by ncbi.nlm.nih.gov (6.5%). (karlsson 2014) journals from ten different fields (n=30) google scholar retrieved documents from all the selected journals; summon only retrieved documents from 14 out of 30 journals. (lee et al. 2015) journal articles housed in florida state university’s institutional repository (n=170) metadata found in google for 46% of items and in google scholar for 75% of items; google scholar found 78% of available full text. google scholar found full text for six items with no full text in the ir. (martín-martín et al. 2014) items highly cited by google scholar (n=64,000) 40% could be freely accessed using google scholar; nih.gov and researchgate were the top two full-text providers. (moed, bar-ilan, and halevi 2016) citations to 36 highly cited articles in 12 scientific-scholarly english-language journals (n=about 7,000) 47% of sources were in both google scholar and scopus; 47% of sources were in google scholar only; 6% of sources were in scopus only; of the unique google scholar citations, sources were most often from google books, springer, ssrn, researchgate, acm digital library, arxiv, and aclweb.org. an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 20 (prins et al. 2016) article citations in the field of education and pedagogies, and citations to 328 articles in anthropology (n=774) google scholar found 22,887 citations in education & pedagogical science compared to web of science’s 8,870, and 8,092 in anthropology compared with web of science’s 1,097. (ştirbu et al. 2015) compared # of citations resulting from two geographical topic searches (samples varied) google scholar found 2,732 geographical references whereas web of science found only 275, georef 97, and francis 45. for sedimentation, google scholar found 1,855 geographical references compared to web of science’s 606, georef’s 1,265, and francis’s 33; google scholar overlapped web of science by 67% and 82% for the two searches, and georef by 57% and 62% (testa 2016) open access journals in music (n=84) google scholar indexed at least one article from 93% of oa journals. rilm indexed two additional journals. (wildgaard 2015) publications from researchers in astronomy, environmental science, philosophy and public health (n=512) publication count from web of science was 2-4 times lower for all disciplines than google scholar; citation count was up to 13 times lower in web of science than in google scholar. (winter, zadpoor, and dodou 2014) growth of citations to 2 classic articles (19952013) and 56 science and social science articles in google scholar, 2005-2013 (samples varied) total citation counts 21% higher in web of science than google scholar for lowry (1951) but google scholar 17% higher than web of science for garfield (1955) and 102% higher for the 56 research articles; google scholar showed a significant retroactive expansion to all articles compared to negligible retroactive growth in web of science. table 1. studies investigating google scholar’s coverage of journal articles and citations, 2014-2016. information technology and libraries | june 2017 21 google scholar coverage: books many studies mentioned that books, including google books, are sometimes included in google scholar results. jamali and nabavi (2015) found 13% of their sample of 8,310 citations from google scholar were books, while martín-martín et al. (2014) had found that 18% of their sample of 64,000 citations from google scholar were books. within the field of anthropology, prins (2016) found books to generate the most citation impact in google scholar (41% of books in their sample were cited in google scholar) compared to articles (21% of articles were cited in google scholar). in education, 31% of articles and 25% of books were cited by google scholar (3). abrizah and thelwall found only 37% of their sample of 1,357 arts, humanities, and social sciences books from the five main university presses in malaysia had been cited in google scholar (23% of the books had been cited in google books) (abrizah and thelwall 2014, 2502). the overlap was small: 15% had impact in both google scholar and google books. the authors concluded that due to the low overlap between google scholar and google books, searching both engines is required to find the most citations to academic books. english books were significantly more likely to be cited in google scholar (48% vs. 32%), as were edited books (53% vs. 36%). they surmised edited books’ citation advantage was due to the use of book chapters in social sciences. they found arts and humanities books more likely to be cited in google scholar than social sciences books (40% vs. 34%) (abrizah and thelwall 2014, 2503). google scholar coverage: grey literature grey literature refers to documents not published commercially, including theses, reports, conference papers, government information, and poster sessions. haddaway et al. (2015) was the only empirical study found focused on grey literature. they discovered that between 8% and 39% of full-text search results from google scholar were grey literature, with the greatest concentration of citations from grey literature on page 80 of results for full-text searches and page 35 for title searches. they concluded “the high proportion of grey literature that is missed by google scholar means it is not a viable alternative to hand searching for grey literature as a standalone tool” (2015, 14). for one of the systematic reviews in their sample, none of the 84 grey literature articles cited were found within the exported google scholar search results. the only other investigation of grey literature found was bonato (2016), who after conducting a very limited number of searches on one specific topic and a search for a known item, concluded google scholar to be “deficient.” in conclusion, despite much offhand praise for google scholar’s grey literature coverage (erb and sica 2015; antell et al. 2013), the topic has been little studied and when it has, grey literature results have not been prominent. google scholar coverage: open access and institutional repository content erb and sica touted google scholar’s access to “free content that might not be available through a library’s subscription services,” including open access journals and institutional repository coverage (2015, 48). recent research has dug deeper into both these content areas. an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 22 in general, oa articles have been shown to net more citations than non-oa articles, as koler-povh, južnic, and turk (2014) showed within the field of civil engineering. across their sample of 2,026 scholarly articles in 14 journals, all indexed in web of science, scopus, and google scholar, oa articles received an average of 43 citations while non-oa articles were cited 29 times (1039). google scholar did a better job discovering those citations; in google scholar the median of citations of oa articles was always higher than that for non-oa articles, wheras this was true in web of science for only 10 of the 14 journals and in scopus for 11 of the 14 journals (1040). similarly, chen (2014) found google scholar to index far more oa journals than scopus and web of science, especially “gold oa.”12 google scholar’s advantage should not be assumed across all disciplines, however; testa (2016) found both google scholar and rilm to provide good coverage of oa journals in music, with google scholar indexing at least one article from 93% of the 84 oa journals in the sample. but the bibliographic database rilm indexed two more oa journals than google scholar. google scholar indexing of repositories may be critical for success, but results vary by ir platform and whether the ir metadata has been structured according to google’s guidelines. in a random sample from shodhganga, india’s central etd database, weideman (2015) found not one article had been indexed in full text by google scholar, although in many cases the metadata was indexed, leading the author to identify needed changes to the way shodhganga stores etds.13 likewise, chen (2014) found that neither google scholar nor google appears to index baidu wenku, a major full-text archive and social networking site in china similar to researchgate, and orduña-malea and lópez-cózar (2015) found that latin american repositories are not very visible in google or google scholar due to limitations of the description schemas chosen as well as search engine reliability. in yang’s (2016) study of texas tech’s dspace ir, google was the only search engine that indexed, discovered, or linked to pdf files supplemented with metadata; google scholar did not discover or provide links to the ir’s pdf files, and was less successful at discovering metadata. when google scholar is able to index ir content, it may be responsible for significant traffic. in a study of four major u.s. universities’ institutional repositories (three dspace, one contentdm) involving a dataset of 57,087 unique urls and 413,786 records, researchers found that 48%–66% of referrals came from google scholar (obrien et al. 2016, 870). the importance of google scholar in contrast to google was noted by lee et al. (2015), who conducted title searches on 170 journal articles housed in florida state university’s institutional repository (using bepress’s digital commons platform), 100 of which existed in full text in the ir. links to the ir were found in google results for 45.9% of the 170 items, and in google scholar for 74.7% of the 170 items. furthermore, google scholar linked to the full text for 78% of the 100 cases where full text was available, and even provided links to freely available full text for six items that did not have full 12 oa articles on publisher web sites, whether the journal itself is oa or not (chen 2014) 13 most notably, the need to store thesis documents as one pdf file instead of divided into multiple, separate files, to create html landing pages as per google’s recommendations, and to submit the addresses of these pages to google scholar. information technology and libraries | june 2017 23 text in the ir. however, the researchers also noted “relying on either google or google scholar individually cannot ensure full access to scholarly works housed in oa irs.” in their study, among the 104 fully open access items there was an overlap in results of only 57.5%; google provided links to 20 items not found with google scholar, and google scholar provided links to 25 items not found with google (lee et al. 2015, 15). google scholar results note the number of “versions” available for each item. in a study of 982 science article citations (including both oa and non-oa) in irs, pitol and degroote found 56% of citations had between four and nine google scholar versions (2014, 603) almost 90% of the citations shown were the publisher version, but of these, only 14.3% were freely available in full text on the publisher web site. meanwhile, 70% percent of the items had at least one free full-text version available through a “hidden” google scholar version. the author’s experience in retrieving full text for this review indicates this issue still exists, but research would be needed to formulate reliable recommendations for users. use and utility of google scholar as part of the research process studies were found concerning google scholar’s popularity with users and their reasons for preferring it (or not) over other tools. another group of studies examined issues related to the utility of google scholar for research processes, including issues related to messy metadata. finally, a cluster of articles focused specifically on using google scholar for systematic reviews. popularity and user preferences several studies have shown google scholar to be well-known to scholarly communities. a survey of 3,500 scholars from 95 countries found that over 60% of 3,500 scientists and engineers and over 70% of respondents in the social sciences, arts, and humanities were aware of google scholar and used it regularly (van noorden 2014). in a large-scale journal-reader survey, inger and gardner (2016) found that among academic researchers in high-income areas, academic search engines surpassed abstracts and indexes as a starting place for research (2016, 85, figure 4). in low-income areas, google use exceeded google scholar use for academic research. major library link resolver software offers reports of full-text requests broken down by referrer. inger and gardner (2016) showed a large variance across subjects for whether people prefer google or google scholar: “people in the social sciences, education, law, and business use google scholar more to find journal articles. however, people working in the humanities and religion and theology prefer to use google” (88). humanities scholar use of google over google scholar was also found by kemman et al. (2013); google, google images, google scholar, and youtube were used more than jstor or other library databases, even though humanities scholars’ trust in google and google scholar was lower. user research since 2014 concerning google scholar has focused on graduate students. results suggest scholar is used regularly but the tool is only partially sufficient. in their study of 20 engineering masters’ students’ use of abstracts and indexes, johnson and simonsen (2015) found an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 24 that half their sample (n=20) had used google scholar the last time they located an article using specific search terms or criteria. google was the second most-used source at 20%, followed by abstracting and indexing services (15%). graduate students describe google scholar with nuance and refer to it as a specific part of their process. in bøyum and aabø’s (2015) interviews with eight phd business students and wu and chen’s (2014, 381) interviews with 32 graduate students drawn from multiple academic disciplines, the majority described using library databases and google scholar for different purposes depending on the context. graduate students in both studies were well aware of google scholar’s use for citation searching. bøyum and aabø’s (2015) subjects described library resources as more “academically robust” than google or google scholar. wu and chen’s (2014) interviewees praised google scholar for its wider coverage and convenience, but lamented the uncertain quality, sometimes inaccessible full text, too many results, lack of sorting function (document type or date), finding documents from different disciplines, and duplicate citations. google scholar was seen by their subjects as useful during early stages of information seeking. in contrast to general assumptions, more than half the students (wu and chen 2014, 381) interviewed reported browsing more than 3 pages’ worth of google scholar results. about half of interviewees reported looking at cited documents to find more, however students had mixed opinions about whether the citing documents turned out to be relevant. google scholar’s “my library” feature, introduced in 2013, now competes with other bibliographic citation management software. in a survey of 344 (mostly graduate) students, conrad, leonard, and somerville found google scholar was the most-used (47%) followed by endnote (37%), and zotero (19%) (2015, 572). follow-up interviews with 13 of the students revealed that a few students used multiple tools, for example one participant noted he/she used “endnote for sharing data with lab partners and others “across the community”; mendeley for her own personal thesis work, where she needs to “build a whole body of literature”; and google scholar citations for “quick reference lists that i may not need for a second or third time.” messy metadata many studies have suggested google scholar’s metadata is “messy.” although none in the period of study examined this phenomenon in conjunction with relative user performance, the issues found could affect scholarship. a 2016 study itemized the most common mistakes in google scholar resulting from its extraction process: 1) incorrect title identification; 2) missing or incorrectly assigned authors; 3) book reviews indexed as books; 4) failing to group versions of the same document, which inflates citation counts; 5) grouping different editions of books, which deflates citation counts; 6) attributing citations to documents that did not cite them, or missing citations that did; and 7) duplicate author profiles (martín-martín et al. 2016b). the authors concluded that “in an academic big data environment, these errors (which we deem affect less than 10% of the records in the database) are of no great consequence, and do not affect the core system information technology and libraries | june 2017 25 performance significantly” (54). two of these issues have been studied specifically: duplicate citations and missing publication dates. the rate of duplicate citations in google scholar has ranged upwards of 2.93% (haddaway et al. 2015) and 5% (winter, zadpoor, and dodou 2014, 1562), which can be compared to a .05% duplicate citation rate in web of science (haddaway et al. 2015, 13). haddaway found the main reasons for duplication include “typographical errors, including punctuation and formatting differences; capitalization differences (google scholar only), incomplete titles, and the fact that google scholar scans citations within reference lists and may include those as well as the citing article” (2015, 13). the issue of missing publication dates varies greatly across samples. dates were found to be missing 9% of the time in winter et al.’s study, although it varied by publication type: 4% of journals, 15% of theses, and 41% of the unknown document types” (winter, zadpoor, and dodou 2014, 1562). however martin-martin et al. studied a sample of 32,680 highly-cited documents and found that web of science and google scholar agreed on publication dates 96.7% of the time, with an idiosyncratically large proportion of those mismatches in 2012 and 2013 (2017, 159). utility for research processes prior to 2014, studies such as asher, duke, and wilson's 2012 evaluated google scholar’s utility as a general research tool, often in comparison with discovery tools. since 2014, the only such study found was namei and young’s comparison of summon, google scholar, and google using 299 known-item queries. they found google scholar and summon returned relevant results 74% of the time; google returned relevant results 91% of the time. for “scholarly formats,” they found summon returned relevant results 76% of the time; google 79%; and google 91% (2015, 526527). the remainder of studies in this category focused specifically on systematic reviews, perhaps because such reviews are so time-consuming. authors develop search strategies carefully, execute them in multiple databases, and document their search methods and results carefully. some prestigious journals are beginning to require similar rigor for any original research article, not just systematic reviews (cals and kotz 2016). information provided by professional organizations about the use of google scholar for systematic reviews seems inconsistent: the cochrane handbook for systematic reviews of interventions lists google scholar among sources for searching, but none of the five “highlighted reviews” on the cochrane web site at the time of this article’s writing used google scholar in their methodologies. the uk organization national institute for health and care excellence’s manual (national institute for health and care excellence (nice)) only mentions google scholar in an appendix of search sources under “conference abstracts.” a study by gehanno et al. (2013) found google scholar contained 100% of the references from 29 systematic reviews, and suggested google scholar could be the first choice for systematic reviews or meta-analyses. this finding prompted a slew of follow-up studies in the next three years. an an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 26 immediate response by giustini and boulos (2013) pointed out that systematic reviews are not performed by searching for article titles as with gehanno et al.’s method, but through search strategies. when they tried to replicate a systematic review’s topical search strategy in google scholar, the citations were not easily discovered. in addition the authors were not able to find all the papers from a given systematic review even by title searching. haddaway et al. also found imperfect coverage: for one of the seven reviews examined, 31.5% of citations could not be found (2015, 11). haddaway also noted that special characters and fonts (as with chemical symbols) can cause poor matching when such characters are part of article titles. recent literature concurs that it is still necessary to search multiple databases when conducting a systematic review, including abstracts and indexes, no matter how good google scholar’s coverage seems to be. no one database’s coverage is complete, including google scholar (thielen et al. 2016), and practical recall of google scholar is exceptionally low due to the 1,000 result limit, yet at the same time, google scholar’s lack of precision is costly in terms of researchers’ time (bramer, giustini, and kramer 2016b; haddaway et al. 2015). the challenges limiting study of google scholar’s coverage also bedevil those wishing to use it for reviews, especially the 1,000 result retrieval limit, lack of batch export, and lack of exported abstracts (levay et al. 2016). additionally, google scholar’s changing content, unknown algorithm and updating practices, search inconsistencies, limited boolean functions, and 256-character query limit prevent the tool from accommodating the detailed, reproducible search methodologies required by systematic reviews (bonato 2016; haddaway et al. 2015; giustini and boulos 2013). bonato noted google scholar retrieved different results with advanced and basic searches; could not determine the format of items (e.g. conference papers); and found other inconsistent results.14 bonato also lamented the lack of any kind of document type limit. despite the limitations and logistical challenges, practitioners and scholars are finding solid reasons for including academic web search engines as part of most systematic review methodologies (cals and kotz 2016). stansfield et al. noted that “relevant literature for lowand middle-income countries, such as working and policy papers, is often not included in databases,” and that google scholar finds additional journal articles and grey literature not indexed in databases (2016, 191). for eight systematic reviews by eppi-center, “over a quarter of relevant citations were found from websites and internet search engines” (stansfield, dickson, and bangpan 2016, 2). specific tools and practices have been recommended when using search engines within the context of systematic reviews. software is available to record search strategies and results (harzing and alakangas 2016b; haddaway 2015). haddaway suggests the use of snapshot tools (haddaway 2015) to record the first 1,000 google scholar records rather than the typical assessment of the first 50 search results as had been done in the past: “this change in practice 14 bonato (2016) found zero hits for conference papers when limiting by year 2015-2016, but found two papers presented at a 2015 meeting. information technology and libraries | june 2017 27 could significantly improve both the transparency and coverage of systematic reviews, especially with respect to their grey literature components.” (haddaway et al. 2015, 15). both haddaway (2015) and cochrane recommend that review authors print or save locally electronic copies of the full text or relevant details rather than bookmarking web sites, “in case the record of the trial is removed or altered at a later stage” (higgins and green 2011). new methods for searching, downloading, and integrating academic search engine results into review procedures using free software to increase transparency, repeatability, and efficiency have been proposed by haddaway and his colleagues (2015). google scholar citations and metrics google scholar citations and metrics are not academic search engines, but this article included them because these products are interwoven into the fabric of the google scholar database. google scholar citations, launched in late 2011 (martín-martín et al. 2016b, 12) groups citations by author, while google metrics (launch date uncertain) provides similar data for articles and journals. readers interested in an in-depth literature review of google scholar citations for earlier years (2005-2012) are directed to (thelwall and kousha 2015b). in his comprehensive review of more recent literature about using google scholar citations for citation analysis, waltman (2016) described several themes. google scholar’s coverage of many fields is significantly broader than web of science and scopus, and this seems to be continuing to improve over time. however studies regularly report google scholar’s inaccuracies, content gaps, phantom data, easily manipulatable citation counts, lack of transparency, and limitations for empirical bibliometric studies. as discussed in the coverage section, google scholar’s citation database is competitive with other major databases such as web of science and has been growing dramatically in the last few years (winter, zadpoor, and dodou 2014; harzing and alakangas 2016b; harzing 2014) but has recently stabilized (harzing and alakangas 2016b). more and more studies are concluding that google scholar will report more comprehensive information about citation impact than web of science or scopus. across a sample of articles from many years of one science journal, trapp (2016) found the proportion of articles with zero citations was 37% for web of science, 29% for scopus, and 19% for google scholar. some of google scholar’s superiority for citation analysis in the social sciences and humanities is due to its inclusion of book content, software, and additional journals (prins et al. 2016; bornmann et al. 2016). bornmann et al. (2016) noted citations to all ten of a research institute’s ten books published in 2009 were found in google scholar, whereas web of science found citations for only two books. furthermore they found data in google scholar for 55 of the total of 71 of the institute’s book chapters. for the four conference proceedings they could identify in google scholar, there were 100 citations, of which 65 could be found in google scholar. the comparative success of google scholar for citation impact varies by discipline, however: (levay et al. 2016) found web of science to be more reliable than google scholar, quicker for an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 28 downloading results, and better for retrieving 100% of the most important publications in public health. despite google scholar’s growth, using all three major tools (scopus, web of science, and google scholar) still seems to be necessary for evaluating researcher productivity. rothfus (2016) compared web of science, scopus, and google scholar citation counts for evaluating the impact of the canadian network of observational drug effect studies (cnodes), as represented by a sample of 222 citations from five articles. attempting to determine citation metrics for the cnodes research team yielded different results for every article when using the three tools. they found that “using three tools (web of science, scopus, google scholar) to determine citation metrics as indicators of research performance and impact provided varying results, with poor overall agreement among the three” (237). major academic libraries’ web sites often explain how to find one’s h-index in all three (suiter and moulaison 2015). researchers have also noted the disadvantages of google scholar for citation impact studies. google scholar is costly in terms of researcher time. levay et al. (2016) estimated the cost of “administering results” from web of science to be 4 hours versus 75 hours for google scholar. administering results includes using the search tool to search, download, and add records to bibliographic citation software, and removing duplicate citations. duplicate citations are often mentioned as a problem (prins et al. 2016), although moed (2016) suggested the double counting by google scholar would occur only if the level of analysis is on target sources, not if it is on target articles.15 downloaded citation samples can still suffer from double counts, however: harzing and alakangas described how cleaning “a fairly extreme case” in their study reduced the number of papers from 244 to 106 (2016b). google scholar also does not identify self-citations, which can dramatically influence the meaning of results (prins et al. 2016). furthermore, researchers have shown it is possible to corrupt google scholar citations by uploading obviously false documents (delgado lópez-cózar, robinson-garcía, and torres-salinas 2014).while the researchers noted traditional citation indexes can also be defrauded, google’s products are less transparent and abuses may not be easily detected. google did not respond to the research team when contacted and simply deleted the false documents to which it had been alerted without reporting the situation to the affected authors, and the researchers concluded: “this lack of transparency is the main obstacle when considering google scholar and its by-products for research evaluation purposes” (453). because these disadvantages do not outweigh google scholar’s seemingly broader coverage, many articles investigate workarounds for using google scholar more effectively when evaluating 15 “if a document is, for instance, first published in arxiv, and a next version later in a journal j, citations to the two versions are aggregated. in google scholar metrics, in which arxiv is included as a source, this document (assuming that its citation count exceed the h5 value of arxiv and journal j) is listed both under arxiv and under journal j, with the same, aggregate citation count (moed 2016, 29). information technology and libraries | june 2017 29 research impact. harzing and alakangas (2016b) recommend the hi index16, which is corrected for career length and co-authorship patterns, as the citation metric of choice for a fair comparison of google scholar with other tools. bornmann et al. (2016) investigated a method to normalize data and reduce errors when using google scholar data to evaluate citations in the social sciences and humanities. researcher profiles can also be used to find other scholars by topic. in a 2014 survey of researchers (n=8,554), dagienė and krapavickaitė found that 22% used a third-party service such as google scholar or microsoft academic to produce lists of their scholarly activities and 63% reported their scholarly record was freely available on the web (2016, 158, 161). google scholar ranked only second to microsoft word as the most frequently used software to maintain academic activity records (160). martín-martín et al. (2016b) examined 814 authors in the field of bibliometrics using google scholar citations, researcherid, researchgate, mendeley, and twitter. google scholar was the most used social research sharing platform, followed by researchgate, with researcherid gaining wider acceptance among authors deemed “core” to the field. only about one-third of the authors created a twitter profile, and many mendeley and researcherid profiles were found empty. the study found google scholar academic profiles’ distinctive advantages to be automatic updates and its high growth rate, with disadvantages of scarce quality control, inherited metadata mistakes from google scholar, and its manipulatability. overall, martin-martin and colleagues concluded that google scholar “should be the preferred source for relational and comparative analyses in which the emphasis is put on author clusters” (57). google scholar metrics provides citation information for articles and journals. in a sample of 1,000 journals, orduña-malea and delgado lópez-cózar found that “despite all the technical and methodological problems,” google scholar metrics provides sound and reliable journal rankings (2014, 2365). google scholar metrics seems to be an annual publication; the 2016 edition contains 5,734 publications and 12 language rankings. russian, korean, polish, ukranian, and indionesian were added this year, while italian and dutch were removed for unknown reasons (martín-martín et al. 2016a). researchers also found that many discussion papers and working papers were removed in 2016. english-language publications are broken into subject areas and disciplines. google scholar metrics often, but not always creates separate entries for each language in which a journal is published. bibliometricians call for google scholar metrics to display the total number of documents published in the publications indexed and the total number of citations received: “these are the two essential parameters that make it possible to assess the reliability and accuracy of any bibliometric indicator” (13). adding country and language of publication and self-citation rates are among the other improvements listed by lopez-cozar and colleagues. 16 harzing and alakangas (2016b) define the hia as the hi norm/academic age. academic age refers to the number of years elapsed since first publication. to calculate hi norm, one divides the number of citations by the number of authors for that paper, and then calculates the h-index of the normalized citation count. an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 30 informing practice the glaring lack of research related to the coverage of arts and humanities scholarship, limited research on book coverage, and relaunch of microsoft academic make it impossible to form a general recommendation regarding the use of academic web search engines for serious research. until the ambiguity of arts and humanities coverage is clarified, and until academic web search engines are transparent and stable, traditional bibliographic databases still seem essential for systematic reviews, citation analysis, and other rigorous literature search purposes. disciplinespecific databases also have features such as controlled vocabulary, industry classification codes, and peer review indicators that make scholars more efficient and effective. nevertheless, the increasing relevance of academic search engines and solid coverage of sciences and social sciences make it essential for librarians to become as expert with google scholar, google books, and microsoft academic. for some scholarly tasks, academic search engines may be superior: for example, when looking up doi numbers for this paper’s bibliography, the most efficient process seemed to be a google search on the article title plus the term “doi,” and the most likely site to display in the results was researchgate.17 librarians and scholars should champion these tools as an important part of an efficient, effective scholarly research process (walsh 2015), while also acknowledging the gaps in coverage, biases, metadata issues and missing features available in other databases. academic web search engines could form the centerpiece for instruction sessions surrounding the scholarly network, as shown by “cited by” features, author profiles, and full-text sources. traditional abstracts and indexes could then be presented on the basis of their strengths. at some point, explaining how to access full text will likely no longer focus on the link resolver but on the many possible document versions a user might encounter (e.g. pre-prints or editions of books) and how to make an informed choice. in the meantime, even though web search engines and repositories may retrieve copious full text outside library subscriptions, college students should still be made aware of the library’s collections and services such as interlibrary loan. when considering google scholar’s weaknesses, it’s important to keep in mind chen’s observation that we may not have a tool available that does any better (antell et al. 2013). while google scholar may be biased toward english-language publications, so are many bibliographic databases. overall, google scholar seems to have increased the visibility of international research (bartol and mackiewicz-talarczyk 2015). while google scholar’s coverage of grey literature has been shown to be somewhat uneven (bonato 2016; haddaway et al. 2015), it seems to include more diversity among relevant document types than many abstracts and indexes (ştirbu et al. 2015; bartol and mackiewicz-talarczyk 2015). although the rigors of systematic reviews may contraindicate the tool’s use as a single source, it adds value to search results from other databases (bramer, giustini, and kramer 2016a). user preferences and priorities should also be taken into account; google 17 because the authority of researchgate is ambiguous, in such cases i then looked up the doi using google to find the publisher’s version. in some cases, the doi was not displayed on the publisher’s result page (e.g., https://muse.jhu.edu/article/197091). information technology and libraries | june 2017 31 scholar results have been said to contain “clutter,” but many researchers have found the noise in google scholar tolerable given its other benefits (ştirbu et al. 2015). google books purportedly contains about 30 million items, focused on u.s.-published and englishlanguage books. but its coverage is hit-or-miss, surprising mays (2015) with an unexpected wealth of primary sources but disappointing harper (2016) with limited coverage of academic health sciences books. recent court decisions have enabled google to continue progressing toward their goal of full-text indexing and making snippet views available for the google-estimated universe of 130 million books, which suggests its utility may increase. google books is not integrated with link resolvers or discovery tools but has been found useful for providing information about scholarly research impact, especially for the arts, humanities, and social sciences. as re-launched in 2016, microsoft academic shows real potential to compete with google scholar in coverage and utility for finding journal articles. as of february 2017 its index contains 120 million citations. in contrast to the mystery of google scholar’s black-box algorithms and restrictive limitations, microsoft academic uses an open-system approach and offers an api. microsoft academic appears to have less coverage of books and grey literature compared with google scholar. research is badly needed about the coverage and utility of both google books and microsoft academic. google scholar continues to evolve, launching a new algorithm for known-item searching in 201618 that appears to work very well. google scholar does not reveal how many items it searches but studies have suggested 160 million documents have been indexed. studies have shown the google scholar relevance algorithm to be heavily influenced by citation counts and language of publication. google scholar has been so heavily researched and is such a “black box” that more attention would seem to have diminishing returns, except in the area of coverage of and utility for arts and humanities research. librarians may find these takeaways useful for working with or teaching google scholar: • little is known about coverage of arts and humanities by google scholar. • recent studies repeatedly find that in the sciences and social sciences google scholar covers as much if not more than library databases, has more recent coverage, and frequently provides access to full text without the need for library subscriptions. • although the number of studies is limited, google scholar seems excellent at retrieving known scholarly items compared with discovery tools. • using proper accent marks in the title when searching for non-english language items appears to be important. 18 google scholar’s blog notes that in january 2016, a change was made so “scholar now automatically identifies queries that are likely to be looking for a specific paper” technically speaking, “it tries hard to find the intended paper and a version that that particular user is able to read” https://scholar.googleblog.com/. an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 32 • finding full text for non-english journal articles may require searching google scholar in the original language. • while google scholar may include results from google books, it appears both tools should be used rather than assuming google books will appear in google scholar. • while google scholar does include grey literature, these results do not usually rank highly. • google scholar and google must both be used to effectively search across institutional repository content. • free full text may be buried underneath the “all x versions” links because the publisher’s web site is usually the dominant version presented to the user. the right-hand column links may help ameliorate this situation, but not reliably. • google scholar is well-known in most academic communities and used regularly; however, it is seldom the only tool used, with scholars continuing to use other web search tools, library abstracts and indexes, and published web sites as well. • experts in writing systematic reviews recommend google scholar be included as a search tool along with traditional abstracts and indexes, using software to record the search process and results. • for evaluating research impact, google scholar may be superior to web of science or scopus, but using all three tools still seems necessary. • as with any database, citation metadata should be verified against the publisher’s data; with google scholar, publication dates should receive deliberate attention. • when google scholar covers some of a major publisher’s content, that does not imply it covers all of that publisher’s content. • google scholar metrics appears to provide reliable journal rankings. research agenda this review of the literature also provides direction for future research concerning academic web search engines. because this review focused on 2014-2016, researchers may need to review studies from earlier periods for methodological ideas and previous findings, noting that dramatic changes in search engine coverage and behavior can occur within only a few years.19 across the studies, some general best practices were observed. when comparing the coverage of academic web search engines, their utility for establishing research impact, or other bibliometric studies, researchers should strongly consider using software such as publish or perish, and to design their research approach with previous methodologies in mind. information scientists have charted a set of clear disciplinary methods; there is no need to start from scratch. even when 19 for example ştirbu found that google scholar overlapped georef by 57% and 62% (ştirbu et al. 2015, 328), compared with a finding by neuhaus in 2006 where scholar overlapped with georef by 26% (2006, 133). information technology and libraries | june 2017 33 performing a large-scale quantitative assessment such as (kousha and thelwall 2015), manually examining and discussing a subset of the sample seems helpful for checking assumptions and for enhancing the meaning of the findings to the reader. some researchers examined the “top 20” or “top 10” results qualitatively (kousha and thelwall 2015), while others took a random sample from within their large-study sample (kousha, thelwall, and rezaie 2011). academic search engines for arts and humanities research research into the use of academic web search engines within arts and humanities fields is sorely needed. surveys show humanities scholars use both google and google scholar (inger and gardner 2016; kemman, kleppe, and scagliola 2013; van noorden 2014). during interviews of 20 historians by martin and quan-haase (2016) concerning serendipity, five mentioned google books and google scholar as important for recreating serendipity of the physical library online. almost all arts and humanities scholars search the internet for researchers and their activities, and commonly expressed the belief that having a complete list of research activities online improves public awareness (dagienė and krapavickaitė 2016). mays’s (2015) practical advice and the few recent studies on citation impact of google books for these disciplines point to the enormous potential for this tool’s use. articles describing opportunities for new online searching habits of humanities scholars have not always included google scholar (huistra and mellink 2016). wu and chen’s interviews with humanities graduate students suggested their behavior and preferences were different from science and technology students, doing more known-item searching and struggling with “semantically ambiguous keywords” that retrieved irrelevant results (2014, 381). platform preferences seem to have a disciplinary aspect: hammarfelt’s (2014) investigation of altmetrics in the humanities suggests mendeley and twitter should be included along with google scholar when examining citation impact of humanities research, while a 2014 nature survey suggests researchgate is much less popular in the social sciences and humanities than in the sciences (van noorden 2014). in summary, arts and humanities scholars are active users of academic web search engines and related tools, but their preferences and behavior, and the relative success of google scholar as a research tool cannot be inferred from the vast literature focused on the sciences. advice from librarians and scholars about the strengths and limitations of academic web search engines in these fields would be incredibly useful. specific examples of needed research, and related studies to reference for methodological ideas: • similar to the studies that have been done in the sciences, how well do academic search engines cover the arts and humanities? an emphasis on formats important to the discipline would be important (prins et al. 2016). • how does the quality of search results compare between academic search engines and traditional library databases for arts and humanities topics? to what extent can the user usefully accomplish her task? (ruppel 2009)? an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 34 • to what extent do academic search engines support the research process for scholarship distinctive to arts and humanities disciplines (e.g. historiographies, review essays)? • in academic search engines, how visible is the arts and humanities literature found in institutional repositories (pitol and de groote 2014)? specific aspects of academic search engine coverage this review suggests that broad studies of academic search engine coverage may have reached a saturation point. however, specific aspects of coverage need additional investigation: • grey literature: although google scholar’s inclusion of grey literature is frequently mentioned as valuable, empirical studies evaluating its coverage are scarce. additional research following the methodology of haddaway (2015) could investigate the bibliographies of literature other than systematic reviews, investigate various disciplines, or use a sample of valuable known items (similar to kousha, thelwall, and rezaie’s (2011) methodology for books). • non-western, non-english language literature: for further investigation of the repeated finding of non-western, non-english language bias (abrizah and thelwall 2014; cavacini 2015), comparisons to library abstracts and indexes would be helpful for providing context. to what extent is this bias present in traditional research tools? hilbert et al. found the coverage of their sample increased for english language in both web of science and scopus, and “to a lesser extent” in google scholar (2015, 260). • books: any investigations of book coverage in microsoft academic and google scholar would be welcome. very few 2014-2016 studies focused on books in google scholar, and even looking in earlier years turned up little research. georgas (2015) compared google with a federated search tool for finding books, so her study may be a useful reference. kousha et al. (2011) found three times as many citations in google scholar than in scopus to a sample of 1,000 academic books. the authors concluded “there are substantial numbers of citations to academic books from google books and google scholar, and it therefore may be possible to use these potential sources to help evaluate research in bookoriented disciplines” (kousha, thelwall, and rezaie 2011, 2157). • institutional repositories: yang (2016) recommended that “librarians of digital resources conduct research on their local digital repositories, as the indexing effects and discovery rates on metadata or associated text files may be different case by case,” and the studies found 2014-2016 show that ir platform and metadata schema dramatically affect discovery, with some irs nearly invisible (weideman 2015; chen 2014; orduña-malea and lópez-cózar 2015; yang 2016) and others somewhat findable by google scholar (lee et al. 2015; obrien et al. 2016). askey and arlitsch (2015) have explained how google scholar’s decisions regarding metadata schema can dramatically affect results.20 libraries who 20 for example, google’s rejection of dublin core. information technology and libraries | june 2017 35 would like their institutional repositories to serve as social sharing platforms for research should consider conducting a study similar to (martín-martín et al. 2016b). finally, a study of ir journal article visibility in academic web search engines could be extremely informative. • full-text retrieval: the indexing coverage of academic search engines relates to the retrieval of full text, which is another area ripe for more research studies, especially in light of the impressive quantity of full text that can be retrieved without user authentication. johnson and simonsen (2015) found that more of the engineering students they surveyed obtained scholarly articles from a free download or getting a pdf from a colleague at another institution than used the library’s subscription. meanwhile, libraries continue to pay for costly subscription resources. monitoring this situation is essential for strategic decision-making. quint (2016) and karlsson (2014) have suggested strategies for libraries and vendors to support broader access to subscription full text through creative licensing and per-item fee approaches. institutional repositories have had mixed results in changing scholars’ habits (both contributors and searchers) but are demonstrably contributing to the presence of full text in the academic search engine experience. when will academic users find a good-enough selection of full-text articles that they no longer need the expanded full text paid for by their institutions? google books similarly to microsoft academic, google books as a search tool also needs dedicated research from librarians and information scientists about its coverage, utility, and/or adoption. a purposeful comparison with other large digital repositories such as hathitrust (https://www.hathitrust.org) would be a boon to practitioners and the public. while hathitrust is transparent about its coverage (https://www.hathitrust.org/statistics_visualizations), specific areas of google books’ coverage have been called into question. weiss (2016) suggested a gap in google books exists from about 1915-1965 “because many publishers either have let it fall out of print, or the book is orphaned and no one wants to go through the trouble of tracking down the copyright owners” and found that copies in google books “will likely be locked down and thus unreadable, or visible only as a snippet, at best” (303). has this situation changed since the court rulings concerning the legality of snippet view? longitudinal studies in the growth of google books similar to (harzing 2014) could illuminate this and other questions about google books’s ability to deliver content. uneven coverage of content types, geography, and language should be investigated. mays noted a possible geographical imbalance within the united states (mays 2015, 26). others noted significant language and international imbalances, and large disciplinary differences (weiss 2016; abrizah and thelwall 2014; kousha and thelwall 2015). weiss and others suggest the implications of google books’ coverage imbalance have enormous social implications: “google and other [massive digital libraries] have essentially canonized the books they have scanned and contribute to the marginalization of those left unscanned” (301). therefore more holistic quantitative investigations of the types of information in google books and possible skewness an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 36 would be welcome. finally, chen’s study (2012) comparing the coverage of google books and worldcat could be repeated to provide longitudinal information. the utility of google books for research purposes also needs further investigation. books are far more prevalently cited in wikipedia than are research articles (thelwall and kousha 2015a). examining samples of wikipedia articles’ citation lists for the prevalence of google books could reveal how dominant a force google books has become in that space. on a more philosophical level, investigating the ways google books might transform scholarly processes would be useful. szpiech (2014) considered how the google books version of a medieval manuscript transformed his relationship with texts, causing a rupture “produced by my new power to extract words and information from a text without being subject to its order, scale, or authority” (78). he hypothesized readers approach google books texts as consumers, rather than learners, whereby “the critical sense of the gestalt” is at risk of being forgotten” (84). have other researchers in experienced what he describes? microsoft academic given the stated openness of microsoft’s new academic web search engine,21 the closed nature of google scholar, and the promising findings of bibliometricians (harzing 2016b; harzing and alakangas 2016a), librarians and information scientists should embark on a thorough review of microsoft academic with similar enthusiasm to which they approached google scholar. the search engine’s coverage, utility for research, and suitability for bibliometric analysis22 all need to be examined. microsoft academic’s abilities for supporting scholarly social networking would also be of interest, perhaps using ward et al. (2015) as a theoretical groundwork. the tool’s coverage and utility for various disciplines and research purposes is a wide-open field for highly useful research. professional and instructional approaches based on user research to inform instructional approaches, more study on user behavior is needed, perhaps repeating herrera’s (2011) study with google scholar and microsoft academic. in light of the recent focus on graduate students, research concerning the use of academic web search engines by undergraduates, community college students, high school students, and other groups would be welcome. using an interview or focus group generates exploratory findings that could be tested through surveys with a larger, more representative sample of the population of interest. studying searching behaviors has been common; can librarians design creative studies to investigate reading, engagement, and reflection when web search engines are used as part of the process? is there a way to study whether the “matthew effect” (antell et al. 2013, 281), the aging citation 21 microsoft’s faq says the company is “adopting an open approach in developing the service, and we invite community participation. we like to think what we have developed is a community property. as such, we are opening up our academic knowledge as a downloadable dataset” and offers the academic knowledge api (https://www.microsoft.com/cognitive-services/en-us/academic-knowledge-api). 22 see jacsó (2011) for methodology. information technology and libraries | june 2017 37 phenomenon (verstak et al. 2014; martín-martín et al. 2016a; davis and cochran 2015), or other epistemological hypotheses are influencing scholarship patterns? a bold study could be performed to examine differences in quality outcomes between samples of students using primarily academic search engines versus traditional library search tools. exploratory studies in this area could begin by surveying students about their use of search tools for research methods courses or asking them to record their research process in a journal, and correlating the findings with their grades on the final research product. three specific areas of user research needed are the use of scholarly social network platforms, researcher profiles, and the influence of these on scholarly collaboration and research (ward, bejarano, and dudás 2015, 178); the performance of google’s relatively new known-item search23 (compared with microsoft academic’s known-item search abilities), and searching in non-english languages. regarding the latter, albarillo’s (2016) method which he applied to library databases could be repeated with google scholar, microsoft academic, and google books. finally, to continue their strong track record as experts in navigating the landscape of digital scholarship, librarians need to research assumptions regarding best practices for scholarly logistics. for example, searching google for article titles plus the term “doi,” then scanning the results list for researchgate was found by this study’s author to most efficiently provide doi numbers: but is this a reliable approach? does researchgate have sufficient accuracy to be recommended as the optimal tool for this task? what is the most efficient way for a scholar to locate full text for a citation? are academic search engines’ bibliographic citation management software export tools competitive with third-party commercial tools such as refworks? another area needing investigation is the visibility of links to free full text in google scholar. pitol and degroote found that 70% percent of the items in their study had at least one free full-text version available through a “hidden” google scholar version (2014, 603), and this author’s work on this review article indicates this problem still exists — but to what extent? also, when free full text exists in multiple repositories (e.g. researchgate, digital commons, academic.edu), which are the most trustworthy and practically useful for scholars? librarians should discuss the answers to these questions and be ready to provide expert advice to users. conclusion with so many users opting to use academic web search engines for research, librarians need to investigate the performance of microsoft academic, google books, and of google scholar for the arts and humanities, and to re-think library services and collections in light of these tools’ strengths and limitations. the evolution of web indexing and increasing free access to full text should be monitored in conjunction with library collection development. to remain relevant to 23 google scholar’s blog notes that in january 2016, a change was made so “scholar now automatically identifies queries that are likely to be looking for a specific paper” technically speaking, “it tries hard to find the intended paper and a version that that particular user is able to read” https://scholar.googleblog.com/. an evidence-based review of academic web search engines, 2014-2016| fagan | https://doi.org/10.6017/ital.v36i2.9718 38 modern researchers, librarians should continue to strengthen their knowledge of and expertise with public academic web search engines, full-text repositories, and scholarly networks. bibliography abrizah, a., and mike thelwall. 2014.

editorial board thoughts: libraries as makerspace? tod colegrove information technology and libraries | march 2013 2 recently there has been tremendous interest in “makerspace” and its potential in libraries: from middle school and public libraries to academic and special libraries, the topic seems very much top of mind. a number of libraries across the country have been actively expanding makerspace within the physical library and exploring its impact; as head of one such library, i can report that reactions to the associated changes have been quite polarized. those from the supported membership of the library have been uniformly positive, with new and established users as well as principal donors immediately recognizing and embracing its potential to enhance learning and catalyze innovation; interestingly, the minority of individuals that recoil at the idea have been either long-term librarians or library staff members. i suspect the polarization may be more a function of confusion over what makerspace actually is. this piece offers a brief overview of the landscape of makerspace—a glimpse into how its practice can dramatically enhance traditional library offerings, revitalizing the library as a center of learning. been happening for thousands of years . . . dale dougherty, founder of make magazine and maker faire, at the “maker monday” event of the 2013 american library association midwinter meeting framed the question simply, “whether making belongs in libraries or whether libraries can contribute to making.” more than one audience member may have been surprised when he continued, “it’s already been happening for hundreds of years—maybe thousands.”1 the o’reilly/darpa makerspace playbook describes the overall goals and concept of makerspace (emphasis added): “by helping schools and communities everywhere establish makerspaces, we expect to build your makerspace users' literacy in design, science, technology, engineering, art, and math. . . . we see making as a gateway to deeper engagement in science and engineering but also art and design. makerspaces share some aspects of the shop class, home economics class, the art studio and science lab. in effect, a makerspace is a physical mashup of these different places that allows projects to integrate these different kinds of skills.”2 building users’ literacies across multiple domains and a gateway to deeper engagement? surely these are core values of the library; one might even suspect that to some degree libraries have long been makerspace. a familiar example of maker activity in libraries might include digital media: still/video photography and audio mastering and remixing. youmedia network, funded by the macarthur patrick “tod” colegrove (pcolegrove@unr.edu), a lita member, is head of the delamare science & engineering library at the university of nevada, reno, nevada. mailto:pcolegrove@unr.edu editorial board thoughts: libraries as makerspace? | colegrove 3 institute through the institute of museum and library services, is a recent example of such effort aimed at creating transformative spaces; engaged in exploring, expressing, and creating with digital media, youth are encouraged to “hang out, mess around, and geek out.” a more pedestrian example is found in the support of users with first-time learning or refreshing of computer programming skills. as recently as the 1980s, the singular option the library had was to maintain a collection of print texts. through the 1990s and into the early 2000s, that support improved dramatically as publishers distributed code examples and ancillary documents on accompanying cd or dvd media, saving the reader the effort of manually typing in code examples. the associated collections grew rapidly, even as the overhead associated with the maintenance and weeding of a collection that was more and more rapidly obsoleted grew more. today, e-book versions combined with ready availability of computer workstations within the library, and the rapidly growing availability of web-based tutorials and support communities, render a potent combination that customers of the library can use to quickly acquire the ability to create or “make” custom applications. with the migration of the supporting print collections online, the library can contemplate further support in the physical spaces opened up. open working areas and whiteboard walls can further amplify the collaborative nature of such making; the library might even consider adding popular hardware development platforms to its collection of lendable technology, enabling those interested to check out a development kit rather than purchase on their own. after all, in a very real sense that is what libraries do—and have done, for thousands of years: buy sometimes expensive technology tailored to the needs and interest of the local community and make it available on a shared basis. makerspace: a continuum along with outreach opportunities, the exploration of how such examples can be extended to encompass more of the interests supported by the library is the essence of the maker movement in libraries. makerspace encompasses a continuum of activity that includes “co-working,” “hackerspace,” and “fab lab”; the common thread running through each is a focus on making rather than merely consuming. it is important to note that although the terms are often incorrectly used as if they were synonymous, in practice they are very different: for example, a fab lab is about fabrication. realized, it is a workshop designed around personal manufacture of physical items— typically equipped with computer controlled equipment such as laser cutters, multiple axis computer numerical controlled (cnc) milling machines, and 3d printers. in contrast, a “hackerspace” is more focused on computers and technology, attracting computer programmers and web designers, although interests begin to overlap significantly with the fab lab for those interested in robotics. co-working space is a natural evolution for participants of the hackerspace; a shared working environment offering much of the benefit of the social and collaborative aspects of the informal hackerspace, while maintaining a focus on work. as opposed to the hobbyist that might be attracted to a hackerspace, co-working space attracts independent contractors and professionals that may work from home. information technology and libraries | march 2013 4 it is important to note that it is entirely possible for a single makerspace to house all three subtypes and be part hackerspace, fab lab, and co-working space. can it be a library at the same time? to some extent, these activities are likely already ongoing within your library, albeit informally; by recognizing and embracing the passions driving those participating in the activity, the library can become central to the greater community of practice. serving the community’s needs more directly, opportunities for outreach will multiply even as it enables the library to develop a laser-sharp focus on the needs of that community. depending on constraints and the community of support, the library may also be well-served by forming collaborative ties with other local makerspace; having local partners can dramatically improve the options available to the library in day-to-day practice, and better inform the library as it takes well-chosen incremental steps. with hackerspace/co-working/fab lab resources aligned with the traditional resources of the library, engagement with one can lead naturally to the other in an explosion of innovation and creativity. renaissance in addition to supporting the work of the solitary reader, “today's libraries are incubators, collaboratories, the modern equivalent of the seventeenth-century coffeehouse: part information market, part knowledge warehouse, with some workshop thrown in for good measure.”3 consider some of the transformative synergies that are already being realized in libraries experimenting with makerspace across the country: • a child reading about robots able to go hands-on with robotics toolkits, even borrowing the kit for an extended period of time along with the book that piqued the interest; surely such access enables the child to develop a powerful sense of agency from early childhood, including a perception of self as being productive and much more than a consumer. • students or researchers trying to understand or make sense of a chemical model or novel protein strand able not only to visualize and manipulate the subject on a two-dimensional screen, but to relatively quickly print a real-world model to be able and tangibly explore the subject from all angles. • individuals synthesizing knowledge across disciplinary boundaries able to interact with members of communities of practice in a non-threatening environment; learning, developing, and testing ideas—developing rapid prototypes in software or physical media, with a librarian at the ready to assist with resources and dispense advice regarding intellectual property opportunities or concerns. the american libraries association estimates that as of this printing there are approximately 121,169 libraries of all kinds in the united states today; if even a small percentage recognize and begin to realize the full impact that makerspace in the library can have, the future looks bright indeed. editorial board thoughts: libraries as makerspace? | colegrove 5 references 1. dale dougherty, “the

university. diana hellyar (hellyard1@southernct.edu) is assistant librarian, hilton c. buley library, southern connecticut state university. © 2021. abstract with the onset of the covid-19 pandemic and the ensuing shutdown of the library building for several months, there was a sudden need to adjust how the hilton c. buley library at southern connecticut state university (scsu) delivered its services. overnight, the library’s virtual chat service went from a convenient way to reach a librarian to the primary method by which library patrons contacted the library for help. in this article, the authors will discuss what was learned during this time and how the service has been adjusted to meet user needs. best practices and future improvements will be discussed. background the buley library started using springshare's libchat service in january 2015. the chat service was accessible as a button in the header of all the library webpages, and the wording would change depending on the availability of a librarian. at buley library, the chat service is only staffed by our faculty librarians. there were other chat buttons on various individual libguides for either specific librarians or for the general library chat. chat was monitored at the research & information desk by the librarian on duty. the first librarian of the day would log into the shared chat account on the reference desk computer. while each librarian had their own account, using a shared account meant that the librarians could easily hand off a chat interaction during a shift change. while the reference desk was typically busy, librarians would only receive a small number of chats per day. between 2015 and 2019, the library saw an average of 250 chats per year. due to the low usage, there was little focus on libchat training for librarians. for more complicated questions, librarians would often recommend that chat users call, email, or schedule an in-person appointment. since libchat was only monitored while librarians were at the reference desk, it was easy to let it become a secondary mode of reference interaction, particularly if there was a surge of in-person reference questions at any given time. due to the covid-19 pandemic, the library quickly shifted from mostly in-person to solely online services. suddenly, libchat was the virtual reference desk and the main mode of patron interaction. despite this change in how the library interacted with the campus, there was only a slight increase in chat usage in the first two months of the closure. in april 2020, we started to explore our options with libchat in the hopes of increasing visibility and usage. mailto:fruehanp1@southernct.edu mailto:hellyard1@southernct.edu information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 2 evaluating chat widget options considering technical implementation the publicly accessible chat interface is made available completely within a webpage, requiring no clients, external applications, or plugins to make it functional. springshare calls this component the libchat widget, and provides a prepackaged set of website code necessary to create the chat interface. within the libchat system there are a few options for widget placement and presentation. at the time of writing, springshare offers four widget types in its libchat product: in-page chat, button pop-out, slide-out tab, and floating.1 when the service is offline, the system replaces the chat interface with a link to library faqs and the option to submit a question for follow-up. at buley library, prior to the covid-19 pandemic shutdown, the button pop-out was the main widget type used to enter a chat session (see fig. 1). figure 1. previous library website header with chat pop-out button in upper right-hand corner. the pop-out button works by opening a separate pop-up window with the chat interface. this allows the user to navigate to other pages in the previous window without disconnecting from the session. one challenge to the pop-up window method is that many web browsers block pop-up windows by default, requiring a user to recognize and override this setting. another option used mainly on librarian profiles and subject guides is the in-page chat, which embeds the chat interface directly on an existing webpage. many times, these chat widgets are connected to a particular user rather than the queue monitored by all librarians. the user will interact with the chat operator in this dedicated section of the webpage. if a user navigates to a different page in the same window or tab it will disconnect from the chat session. these widget options are easiest when considering web design expertise and time commitment involved in implementation. both the button pop-out and in-page chat can be accomplished with a user having access to a what you see is what you get, or wysiyg, editor on the webpage and the ability to copy and paste a few lines of html code. it does not require any custom <script> elements to be placed in the page <head> or footer area. choosing the floating widget when the library shifted to all virtual services, there was concern that the chat button could easily be missed by library patrons. it was decided at this point to investigate alternative options to invite patrons to chat with librarians. the floating chat widget was chosen as the best option and was integrated into the website during a theme update in may 2020. the floating chat widget was made widely available to springshare libchat users in 2017.2 this widget operates by placing a chat icon at the bottom right of a webpage. this icon remains visible in this location while users scroll down a page. another option is to implement this icon as a proactive widget which displays a message to users after a set number of seconds to invite them to start a chat session (see fig. 2). information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 3 figure 2. floating chat widget on the redesigned library homepage with the proactive setting enabled (pop-up modal) to invite users to begin a chat. a pop-out button is also on the library homepage for patrons who were accustomed to the previous version. implementing this type of widget requires an administrator level of access to the website content management system if it is to be implemented across an entire website. a single <script> tag in the <head> section of the site template will activate it across an entire site. the floating chat widget is a common feature widely seen in the business world and on retailer websites. the hesitation in implementing this type of widget was that it would be perceived by patrons as intrusive or annoying. however, one study reported finding that college students found it useful.3 additionally, several other libraries have written previously about their success in implementing a proactive chat widget.4 it was decided that the library would implement this proactive chat widget on a trial basis and then evaluate the outcome as to whether to continue or not. shortly after, it was decided to add another proactive chat widget to southernsearch, the library’s discovery platform, built on ex libris primo (see fig. 3). the primo new ui, built on nodejs, is more complex to implement as it requires building a javascript function to insert the chat widget information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 4 script code into the application for nodejs to render on the front-end. this process is well documented by laura guy of the colorado school of mines.5 figure 3. embedded chat widget in southernsearch discovery platform. the pop-up modal is hidden in this view. libchat in action in active chats the ask a librarian chat became the library’s virtual reference desk when the university closed its campus in march 2020 due to the covid-19 pandemic. with the new focus on chat, the librarians decided it was time for a refresher on libchat. training was also necessary due to an update to the librarian libchat dashboard. a virtual training session was held to show librarians how to use the new dashboard and to remind everyone how best to use chat since it was infrequently used prior to closing in-person services. the training was recorded, and a link was provided to everyone so librarians could watch the training again as needed. the libchat widget change caused a huge increase in daily chat numbers. the library received 47 chats in april with the chat button. the total spiked to 160 in may with the floating chat widget. historically, there is a decrease in both virtual and in-person reference interactions during the month of may. librarians were answering more chats than ever before. however, some librarians information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 5 still had questions or technical troubles that did not get asked until after a chat ended. there was a need for a place to address these questions ahead of time so answers could be provided at the point of need. in response, a libchat best practices guide was created soon after the widget change to have a place to house tips for effective chat interactions and for quick troubleshooting answers. the best practice guide was well received by librarians; however, it was underutilized. libchat administrators hoped to be able to add a link to it directly within the dashboard for quick reference if librarians had an issue during a live chat, but they were unable to do so. the librarians added new canned messages to increase efficiency and consistency among common patron needs. canned messages are commonly used prewritten statements that can be utilized by all librarians on chat. they can be created by an administrator to be used by any librarian and can be easily added to any active chat. for example, librarians created messages for bookstore contact information, how to request electronic delivery of journal articles, and the library’s hours. privacy considerations the library’s chat system is capable of capturing data that comprises personally identifiable information (pii) for a patron. an intentional decision was made to limit this collection as much as possible in keeping with the principles of ala’s stance on patron privacy in the library bill of rights, which as interpreted says: the right to privacy includes the right to open inquiry without having the subject of one’s interest examined or scrutinized by others, in person or online. confidentiality exists when a library is in possession of personally identifiable information about its users and keeps that information private on their behalf.6 the chat login form asks a patron for information before starting a chat; that information can include name, contact information (such as email or phone numbers), and up to three customized questions. additionally, the system automatically captures the referrer url and the user’s public ip address, browser, and operating system. while it would be helpful to have more information up front, this could lead to the collection of a wealth of pii. with these concerns in mind, it was decided to make pii such as name, email address , and phone numbers an optional entry. while knowing a name and email address is useful when the librarian would like to follow up on a question or if a chat session is unintentionally disconnected, it is not necessary. the librarian may request this information later in the chat if needed. handling harassment and inappropriate behavior in june, one chat patron caused an immediate change in the operation of libchat at the library. on this day, a librarian answered an incoming chat, and a hostile patron threatened the librarian. before the situation could be addressed, another question from an anonymous patron came into the queue. a second librarian, who happened to be one of this article’s authors, claimed the chat despite being aware of the situation and suspecting this was the same difficult patron. it began as a normal interaction but eventually they became inappropriate. the librarian warned the patron multiple times before finally ending the chat and blocked their ip address. in response, the patr on left an inappropriate comment on the ratings and comments survey after the chat interaction finished. this one patron interaction made the librarians realize that they were vulnerable to harassment and other hostile behavior. changes were made to help create a safe environment for librarians information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 6 and patrons. first, training and instructions were provided so every librarian knew how to ban a user’s ip address. it was made clear that those ip addresses could be reinstated if a mistake was made. the list is checked on occasion to determine if any decision needed to be reverted or if a university ip address was inadvertently banned. this is especially important if one bans the ip address assigned to the university edge router, a critical network device from which all campus http traffic originates. this could block all users on campus from accessing libchat. additionally, some librarians also chose to change their names from the default option which is full first and last name. many changed their display name, using a combination of their first names, and subject liaison specific job titles. a decision was also made to turn off the chat rating and comment survey. it was not useful for the library’s own assessment purposes as most chat interactions were left unrated. leaving it in place could lead to more inappropriate behavior as comments can be left by a patron even after being banned. most importantly, the librarians created a virtual reference policy. while there was an existing general reference policy in place, it did not focus on, nor specifically mention, online conduct. librarians agreed that it was time to create an additional policy since the increase in usage identified new concerns. the policy gave librarians grounds to ban patrons if needed, informing them that inappropriate conduct was against the virtual reference policy, and disclosed the librarian’s right to report inappropriate behavior to campus authorities. a canned message was created to allow librarians to quickly inform a patron before banning the ip address and ending the chat. the message warns the patron their behavior violates the virtual reference policy and links to the library’s research & instruction policies page where the policy is included. in the beginning of the fall 2020 semester students returned to school, both on campus and virtually. as shown in figure 1, there was a huge spike in chat questions at the beginning of the semester. typical questions included those about borrowing textbooks, using study rooms, and research questions. librarians could sometimes tell if chats were from scsu students or employees if the patron provided their school email address. librarians started seeing another interesting trend with the referrer url. it was noticed that subject guides see more chat patrons who provide non-university email addresses or provide no contact information. when asked, patrons respond they were not affiliated with scsu. it is suspected that non-scsu patrons find the library’s subject guides through a search engine and while exploring the page the floating chat prompts them to chat with a librarian. the floating chat widget has helped to inform us about outside traffic to some of our guides. this has encouraged the library to take a more proactive approach to libguide maintenance among subject librarians, especially the small number of guides with heavy chat traffic. information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 7 observing patron usage figure 4. total number of chats per month from january to december 2020. best practices the lessons learned from the increased chat usage have helped shape a better approach to virtual reference services and create better experiences for the librarians and patrons using the service. with that, here are some considerations and recommendations to expand virtual reference or chat services at other libraries: • use a persistent chat widget with pop-up notifications on all library pages to remind patrons that immediate help is available. • consider patron privacy when making decisions about chat settings. • have policies in place that cover virtual services, such as chat, that includes language on harassment and other inappropriate behavior. • use the policy language for a canned message so librarians can reply quickly if there is an issue. • be prepared for non-university affiliated patrons using chat services, especially from subject guides easily found through search engines. what’s next at buley library there are a few anticipated changes for the buley library chat service in the future. the library’s student advisory board praised the library chat, sharing they found it to be a great way for students to be able to contact librarians for help. however, they did suggest the library consider the branding of the service. their recommendation was to make it clear before a patron starts an information technology and libraries september 2021 expanding and improving our library’s virtual chat service | fruehan and hellyar 8 interaction that a real scsu librarian would be answering the chat. they felt as though students may think that the answerer would be a chat bot or from a call center and not a real librarian that works for the school. additionally, librarians will re-evaluate chat coverage schedules based on usage data. the current schedule is based on in-person desk coverage. however, in-person historical statistics do not translate well to online reference services; busy periods for in-person reference services may not be the case for the same period online. the trend appears to show that weekend chat transactions exceed those of in-person transactions during the same period a year previously. noticing this trend, chat scheduling may need to be adjusted to better align demand with librarian availability. these adjustments could include longer shifts scheduled less frequently rather than daily hour long shifts. chat allows for more multitasking, so a longer shift may be preferable. it might help the librarian adjust their own schedule in preparation for a longer chat shift. chat coverage may need to be evaluated again when the library eventually goes back to operating an in-person reference desk. one pressing question is, will chat demand go back to pre-covid levels, or will it remain high when an in-person reference desk returns? while an in-person reference desk is likely to come back in the future, if chat traffic remains high, a separate schedule may be needed for chat in addition to the reference desk, so the same person is not operating both at the same time. conclusion it may never be known if the increase in chat volume came from the widget updates or was due solely to the pandemic, but it is likely a bit of both. increased chat volume seems to correlate strongly with implementing the floating chat widget, even though there was already an increase due to the effects of the pandemic shutdown. it is planned to look in depth at all available chat data and compare it to in-person reference statistics. another area for further research is the textual analysis of chat transcripts to find trends and make recommendations for greater effectiveness. endnotes 1 “springboard tutorials: create libchat widgets,” springshare help center,

principles of format design henriette d. avram and lucia j. rather: marc development office, library of congress 161 this paper is a summary of several working papers prepared for the international federation of library associations (ifla) working group on content designators. the first working paper, january 1973, discussed the obstacles confronting the worldng group, stated the scope of responsibility for the working group, and gave definitions of the terms, tags, indicator and data element identifiers, as well as a statement of the function of each.1 the first paper was submitted to the working group for comments and was subsequently modified (revised aprill973) to reflect those comment$ that were applicable to the scope of the working group and to the definit·ion and function of content designators. the present paper makes the basic assumption that there will be a supermarc and discusses principles of format design. this se1·ies of papers is be·ing published in the interest of almting the library community to intemational activities. all individual working papers are submitted to the marbi interdivisional committee of ala by the chairman of the ifla working group for comments by that committee. introduction in order to have this paper stand alone, the scope and the definition and functions of the content designators as agreed to by the working group are summarized below: 1. the scope of responsibility for the ifla working group is to arrive at a standard list of content designators for different forms of material for the international interchange of bibliographic data. 2. the definition and function of each content designator are given as: a. a tag is a string of characters used to identify or name the main content of an associated data field. the designation of main content does not require that a data field contain all possible data elements all the time. b. an indicator is a character associated with a tag to supply additional information about the data field or parameters for the processing of the data field. there may be more than one indicator per data field. 162 ] ournal of lib1'a1'y automation vol. 7 i 3 september 197 4 c. a data element identifier is a code consisting of one or more characters used to identify individual data elements within a data field. the data element identifier precedes the data element which it identifies. d. a fixed field is one in which every occurrence of the field has a length of the same fixed value regardless of changes in the contents of the fixed field from occurrence to occurrence. the content of the fixed field can actually be data content, or a code representing data content, or a code representing information about the record. basic assumption-supermarc there appears to be little doubt that the format used for international exchange will not be the format presently in use in any national system. the first working paper addressed the obstacles that preclude complete agreement on any single national format, and a study of the matrix of the content designators assigned by various national agencies substantiates the above conclusion. consequently, we are concerned with the development of a supermarc whereby national agencies would translate their local format into that of the supermarc format and conversely, each agency would accept the supermarc format and translate it into a format for local processing. 2• 3 supermarc, therefore, is an international exchange format with the principal function that of transferring data across national boundaries. it is not a processing format (although if desired, it could be used as such) and in no way dictates the record organization, character bit configuration, coding schemes, etc., to be used within processing agencies. the supermarc format, however, should conform to certain conventions, namely the format structure should be iso 2709 and the character representation should be an eight-bit extension of iso 646. ~ the latter convention means that data cannot be in any other configuration than a character-by-character representation. supermarc assumes not only agreement on the value of content designators but, equally as important, on the level of application of these content designators. whatever the agreed upon level of content designation is, those agencies with formats more detailed will be able to translate to supermarc but will be in the position of having to upgrade all records entered into their local system from other agencies. likewise, local formats consisting of less detailed content designation than supermarc must upgrade to the supermarc level for communication purposes. where the actual content of the record is concerned, i.e., the fields andjor data elements to be included, it is highly probable that the decision of the content designator working group will be that data, if in~ iso/tc 46/sc4 wgl is presently engaged in the definition of extended characters for roman, cyrillic, and greek alphabets and mathematics and control symbols. principles of format design/ avram and rather 163 eluded in the record, are assigned supermarc content designators, but that not all data will always be present. this permits the flexibility required to bypass some of the substantive problems of different cataloging rules and cataloging systems. for example, one agency may supply printer and place of printing while another may not. it may be assumed, however, that all agencies will conform to the specifications prescribed by the isbd and other such standard descriptions as they become available. principles of format design prior to any deliberation regarding the actual value of content designators, the working group realized it must agree on a set of basic principles for the design of the international format. the first working paper set forth, in the form of questions, some of the issues that must be taken into account in arriving at the principles. several members of the working group expressed their opinions and these were considered in the formulation of the principles. the principles were discussed at the grenoble meeting in august 1973. five of the principles were adopted and the sixth was deferred for further analysis based on working papers to be written by some of the members. the sixth principle was adopted at the brussels meeting in february 1974. the six basic principles are stated below with a discussion following each principle: 1. the international format should be designed to handle all media. it would be ideal if at this time all forms of material had been fully analyzed. this is currently not the case. agreement on data fields and the assignment of content designators can realistically only be accomplished if there is a foundation upon which to build. therefore, the forms of material have been limited to those listed below because, to the best of our knowledge, these are the only forms where either experience has been gained in the actual conversion to machine-readable form or in-depth analysis has been performed to define the elements of information for the material. books: all monographic printed language materials. serials: all printed language materials in serial form. maps: printed maps, single maps, serial maps, and map collections. films: all media intended for projection in monographic or serial form. music and sound recordings: music scores and music and nonmusic sound recordings. at the meeting in brussels, the decision was made to use the isbd as the foundation for the definition of functional areas for the formats. since at the present time an isbd exists only for monographs and serials, these materials will receive first priority by the ifla working group. · still under consideration is the question whether manuscripts should be included in the forms of material within the scope of the 164 j oumal of lihra1'y automation vol. 7 i 3 september 197 4 working group. pictorial representations and computer mediums have not as yet been analyzed. when these forms have been analyzed, they should be added to the generalized list. 2. the inte1'national fo1'mat should accept single-level and multilevel st1'uctu1'es. there is a requirement to express the relationship of one bibliographic entity to another. this relationship may take many forms. a hierarchical relation is expressed for works which are part of a larger bibliographic entity (such as the chapter of a book, a single volume of a multivolume set, a book within a series). a linear relation is expressed for works which are related to other works such as a book in translation. this discussion is concerned with hierarchical relationships and the need to describe this relationship in machinereadable records. there are a number of ways in which hierarchical relationships may be expressed. one method is to place the information on the related work in a single field within the record. for example, the different volumes of a multivolume set may be carried in a contents field. when a book is in a series, the series may be caltied in a series field. this may be termed using a single-level record to show a hierarchical relationship. another method is to use a multilevel record made up of subrecords.t the concept of a subrecord directory and a subrecord relationship field was discussed in appendix ii to the ansi standard z39.2-197!.4 the appendix illustrated a possible method of handling subrecords and expressing relationships within a bibliographic record but was not part of the american standard. similarly, in 1968 the library of congress published as part of its marc ii format a proposal to provide for the bibliographic descriptions of more than one item in a single record, and represented this capability as "levels" of bibliographic description. 5 the international standard (iso 2709) defines a subrecord technique without an explicit statement of a method to describe relationships. 6 more recently, a level structure was proposed in a document by john e. linford,7 and an informal paper by richard coward8 gave the following example of a level structure: level collection sub-collection document analytical record 1 subrecord 1 subrecord 1 subrecord r------1------, 1 subrecord 1 subrecord 1 subrecord t a subrecord is a "group of fields within a bibliographic record which may be treated as a logical entity." when a bibliographic record describes more than one bibliographic unit, the descriptions of the individual bibliographic units may be treated as subrecords. principles of format design/ avram and rather 165 several national ,agencies have expressed concern regarding the efficiency of the iso 2709 subrecord technique and have suggested that a modification be made to the subrecord statement. there are alternative techniques which could be incorporated in the international exchange format to build in level capability. methods have been suggested that would cause a revision (specifically the number of characters in each directory entry) to the iso standard; other alternatives might not. regardless of the final technique agreed upon, national agencies should maintain the authority to record their cataloging data to reflect their catalog practices, i.e., either describing the items related to an item cataloged as fields within a single-level record or as subrecords of a multilevel record. 3. tags should identify a field by type of entry as well as function by assigning specific values to the charactet positions. assigning values to the characters of the tags allows the flexibility to derive more than a single kind of information from the tag. for example, it should be possible by an inspection of the tags to retrieve all personal names from a machine-readable record regardless of the function of the name in the record, i.e., principal author, secondary author, name used as subject, etc. 4. indicatots should be tag dependent and used as consistently as possible across all fields. indicators should be tag dependent because they provide both descriptive and processing information about a data field. if the value assigned to an indicator is used as consistently as possible across all fields, where the situation warrants this equality, the machine coding is simplified to process different functional fields containing the same type of entry. 5. data element identifiets should be tag dependent, but, as fat as possible, common data elements should be identified by the same data element identifiets actoss fields. the principle has been adopted that the format will handle all types of media and consequently the projected number of unique tags may be quite large. in addition, since all types of media are not yet fully analyzed, the number of unique fields is an unknown factor. while it is undeniable that making data element identifiers tag independent would be desirable, the limited number of alphabetic, numeric, and symbolic characters would restrict the number of data elements to the number of unique characters. this constraint on future expansion seems to be more important than any advantages gained from making data element identifiers tag independent. if data element identifiers are tag dependent, then additional refinements could be added in one of two ways: ( 1) the principle of identifying common data elements by the same identifiers across fields could be followed as far as possible, 01' ( 2) the identifiers could be given a value to aid in filing. the two refinements appear to be mutu166 journal of library automation vol. 7/3 september 197 4 ally exclusive since a data element in one field may have a different filing value from the same data element in another field. since the first refinement should be useful for many types of processing, and the second would be useful only in filing, the former seems to be the better option. 6. the fields in a bibliographic record are primarily related to broad categories of information relating to "sttbfect," "description," "intellectual1'esponsibility," etc., and should be grouped according to these fundamental categories. the first working paper discussed as an obstacle the lack of agreement on the organization of data content in machine-readable records in different bibliographic communities. a subsequent paper consisting of comments made by staff of the library of congress on the proposed eudised format discussed in greater detail the analytic versus traditional arrangement. 9 • t the majority of the national formats designed to date are arranged by using the function as the primary grouping and the type of entry as the secondary grouping. several working papers produced by committee members supported the arrangement by function on the grounds that it followed the traditional order of elements in the bibliographic record and therefore simplified input procedures. grouping of the fields first by function and then by type of entry was agreed to at the brussels meeting. references 1. henriette d. avram and kay d. guiles, "content

of southern mississippi libraries website conducted in early 2016. the study involved six participants from each of four key user groups— undergraduate students, graduate students, faculty, and library employees—and consisted of six typical library search tasks, such as finding a book and an article on a topic, locating a journal by title, and looking up hours of operation. library employees and graduate students completed the study’s tasks most successfully, whereas undergraduate students performed relatively simple searches and relied on the libraries’ discovery tool, primo. the study’s results displayed several problematic features that affected each user group, including library employees. these results increased internal buy-in for usability-related changes to the library website in a later redesign. introduction within the last decade, usability testing has become a common way for libraries to assess their websites. eager to gain a better understanding of how users experience our website, we assembled a two-person team and conducted the first usability study of the university of southern mississippi libraries website in february 2016. the web advisory committee—which is tasked with developing, maintaining, and enhancing the libraries’ online presence—wanted to determine if the content on the website was organized in a way that made sense to users and facilitated the efficient use of the libraries’ online resources. our usability study involved six participants from each of the following library user groups: undergraduate students, graduate students, faculty, and library employees. student and faculty participants represented several academic disciplines and departments. all of the library employees involved in the study work in public-facing roles. the web advisory committee and libraries’ administration wanted to know how each of these groups differ in their website use and whether they have difficulty with the same architecture or features. usability testing helped illuminate which aspects of the website’s design might be hindering users from accomplishing key tasks, thereby identifying where and how improvement needed to be made. we included library employees in this study to compare their approach to the website to that of other users in the mailto:elena.azadbakht@usm.edu mailto:john.blair@usm.edu mailto:lisa.r.jones@usm.edu everyone’s

discuss the usability study’s design, results, and recommendations as well as the implications of the study’s findings for similarly situated academic libraries. we will give special consideration to how the behavior of library employees compared to that of other groups. literature review the literature on library-website user experience and usability is extensive. in 2007, blummer conducted a literature review of research related to academic-library websites, including usability studies. her article provides an overview of the goals and outcomes of early library-website usability studies. 1 more recent articles focus on a portion or aspect of a library’s website such as the homepage, federated search or discovery tool, or subject guides. fagan published an article in 2010 that reviews user studies of faceted browsing and outlines several best practices for designing studies that focus on next-generation catalogs or discovery tools. 2 other library-website studies have reported on the habits of user groups, with undergraduates being the most commonly studied constituent group. emde, morris, and claassen-wilson observed university of kansas faculty and graduate students’ use of the library website, which had been recently redesigned, including a new federated search tool. 3 many of the study’s participants gravitated toward the subject-specific resources they were familiar with and either missed or avoided using the website’s new features. when asked for their opinions on the federated search tool, several participants said that while it was not a tool they saw themselves using, they did see how it might be a helpful for undergraduate students who were still new to research. the researchers also provided the participants with an article citation and asked them to locate it using the using the library’s website or online resources. while half the participants did use the website’s “e-journals” link, others were less successful. some who had the most difficulty “search[ed] for the journal title in a search box that was set up to search database titles.” 4 this led emde, morris, and claassen-wilson to observe that “locating journal articles from known citations is a difficult concept even for some advanced researchers.” turner’s 2011 article describes the result of a usability study at syracuse university library that included both students and library staff. participants were asked to start at the library’s homepage and complete five tasks designed to emulate the types of searches a typical library user might perform, such as finding a specific book, a multimedia item, an article in the journal nature, and primary sources pertaining to a historic event. 5 when asked to find toni morrison’s beloved, most staff members used the library’s traditional online catalog whereas students almost always began their searches with the federated search tool located on the homepage. participants of both types were less successful at locating a primary source, although this task highlighted key differences in each groups’ approach to searching the library website. since library staff were more familiar than students with the library’s collections and online search tools, they relied more on facets and limiters to narrow their searches, and some even began their searches by navigating to the library’s webpage for special collections. information technology and libraries |december 2017 36 library staff tended to be more persistent; draw upon their greater knowledge of the library’s collections, website, and search tools; and use special syntax in their searchers, like inverting an author’s first and last names. “library staff took more time, on average, to locate materials,” writes turner, because of their “interest in trying alternative strategies.” 6 students, on the other hand, usually included more detail than necessary in their search queries (such as adding a word related to the format they were searching for after their keywords) and could not always differentiate various types of catalog records, for example, the record for a book review and the record for the book itself. turner concludes that the students’ mental models for searching online and their experiences with other web-search environments influence their expectations of how library search tools work and that library-website design should take these mental models into consideration. research on the search behaviors of students versus more experienced researchers or subject experts also has implications for library website design. two recent articles explore the different mental models or mindsets students bring to a search. the students in asher and duke’s 2012 study “generally treated all search boxes as the equivalent of a google search box” and used very simple keyword searches. 7 this tracked with holman’s 2010 study, which likewise found that the students she observed relied on simple search strategies and did not understand how search interfaces and systems are structured. 8 methods our research team consisted of the libraries’ health and nursing librarian and the web services coordinator. we worked closely with the head of finance and information technology in designing and running the usability study. a two-week period in mid-february 2016 was chosen for usability testing to avoid losing potential participants to midterms or spring break. we posted a call for participants to two university discussion lists, on the libraries website, and on social media (facebook and twitter). we also reached out directly to faculty in academic departments we regularly work with and emailed library employees directly. we directed nonlibrary participants to a web form on the libraries website to provide their name, contact information, university affiliation/class standing, and availability. the health and nursing librarian followed up with and scheduled participants on the basis of their availability. each student participant received a ten-dollar print card and each faculty participant received a ten-dollar starbucks gift card. to record the testing sessions, we needed a free or low-cost software option. since the libraries already had a subscription to screencast-o-matic to develop video tutorials, and the tool allows for simultaneous screen, audio, and video capture, so we decided to use it to record all testing sessions. we also used a spare laptop with an embedded camera and microphone. the health and nursing librarian served as both facilitator and note-taker for most usability testing sessions. participants were given six tasks to complete. we encouraged participants to everyone’s invited | azadbakht, blair, and jones 37 https://doi.org/10.6017/ital.v36i4.9959 narrate as they completed each task. the sessions began with simple, secondary navigational questions like the following: • how late is our main library open on a typical monday night? • how could you contact a librarian for help? • where would you find more information about services offered by the library? next, we asked the participants to complete tasks designed to assess their ability to search for specific library resources and to illuminate any difficulty users might have navigating the website in the process. each of the three tasks focused on a particular library-resource type, including books, articles, and journals: • find a book about rabbits. • find an article about rabbits. • check to see if we have a subscription/access to a journal called nature. after the usability testing was complete, we reviewed the recordings and notes and coded them. for each task, we calculated time to completion and documented the various paths participants took to answer each question, noting any issues they encountered. we also compared the four user groups in our analysis. limitations although we controlled for user type (undergraduate, graduate, faculty, or library employee) in the recruitment of study participants, we did not screen by academic discipline. doing so would have hindered our team’s ability to include enough graduate students and faculty members in the study, as nearly all the volunteers from these two groups were from humanities or social science fields. the results might have differed slightly had the study successfully managed to include more faculty from the so-called hard sciences and allied health fields. additionally, the order in which we asked participants to attempt the tasks might have affected how they approached some of the later tasks. if a participant chose to search for a book using the primo discovery tool, for example, they might be more inclined to use it to complete the next task (find an article) rather than navigate to a different online resource or tool. despite these limitations, usability testing has helped improve the website in key ways. we plan to correct for these limitations in future studies. results every group included a participant who failed to complete at least one of the six tasks. an adequate answer to each of the study’s six tasks can be found within one or two pages/clicks from the libraries homepage (figure 1). the average distance to a solution remained at about two page loads across all of the study’s participants, despite a few individual “website safaris.” information technology and libraries |december 2017 38 figure 1. university of southern mississippi libraries’ homepage. graduate students tended to complete tasks the quickest and were generally as successful as library employees. they preferred to use primo for finding books but tended to favor the list of scholarly databases on the “articles & databases” page to find articles and journals. undergraduates were the second fastest group, but many struggled to complete one or more of the six tasks. they had the most trouble finding books and locating the journal by title. undergraduates generally performed simple searches and had trouble recovering from missteps. they were heavy users of primo, relying on the discovery tool more than any other group. the other two user groups, faculty and library employees, were slower at completing tasks. of the two, faculty took the longest to complete any task and failed to complete tasks at a similar rate as undergraduates. likewise, this group favored primo nearly as often. in contrast, library employees took almost as long as faculty to complete tasks but were much more successful. as a group, library employees demonstrated the different paths users could take to complete each task but favored those paths they identified as the “preferred” method for finding an item or resource over the fastest route. everyone’s invited | azadbakht, blair, and jones 39 https://doi.org/10.6017/ital.v36i4.9959 the majority of study participants across all user groups had little trouble with the first three tasks. although most participants favored the less direct path to the libraries’ hours—missing the direct link at the top of the homepage (figure 2)—they spent relatively little time on this task. likewise, virtually all participants took note of the links to our “ask-a-librarian” and “services” pages located in our homepage’s main navigation menu. this portion of the usability study alerted us to the need for a more prominent display of our opening hours on the homepage. figure 2. link to “hours” from the homepage. of the second set of tasks—find a book, find an article, and determine if we have access to nature—the first and last proved the most challenging for participants. one undergraduate was unable to complete the book task, and one faculty member took nearly eight minutes to do so—the longest time to completion of any task by any user in the study. primo was the most preferred method for finding a book. although an option for searching our classic catalog (which uses innovative interfaces’ millennium integrated library system) is contained within a search widget on the homepage, primo is the default search option and therefore users’ default choice. interestingly, even after statements from some faculty such as “i don’t love primo,” “primo isn’t the best,” and “the [classic catalog] is better,” these participants proceeded to use primo to find a book. library employees were evenly split between primo and classic catalog. one undergraduate student, graduate student, and library employee were unable to determine whether we have access to nature. this task was the most time consuming for library employees because there are multiple ways to approach this question and library employees tended to favor the most consistently successful yet most time-consuming options (e.g., searching within the classic catalog). lacking a clear option in the main navigation bar, the most popular path started information technology and libraries |december 2017 40 with our “articles & databases” page, but the answer was most often successfully found using primo. several participants tried using the “search for databases” search box on the “articles & databases” page, which yielded no results because it searches only our database list. the search widget on the homepage that includes primo has an option for searching e-journals by title, as shown in figure 3. however, nearly all nonlibrary employees missed this feature. participants from both the undergraduate and graduate student user groups had trouble with this task, including those who were ultimately successful. unfortunately, many of the undergraduates could not differentiate a journal from an article, and while graduate students were aware of the distinction, a few indicated that they were not used to the idea of finding articles from a specific journal. figure 3. e-journals search tab. when it came to finding articles, undergraduates, as well as several faculty and a few library employees, gravitated toward primo. others, particularly graduate students and library employees, opted to search a specific database—most often academic search premier or jstor. however, those who used primo to answer this question arrived at an answer two to three times faster because of the discovery tool’s accessibility from a search widget on the homepage. regardless of the tool or resource they used, most participants found a sufficient result or two. common breakdowns despite the clear label “search for databases,” at least one participant from each user group, including library employees, attempted to enter a book title, journal name, or keyword into the libguides’ database search tool on our “articles & databases” page (figure 4). some participants attempted this repeatedly despite getting no results. others did not try a search but stated, with everyone’s invited | azadbakht, blair, and jones 41 https://doi.org/10.6017/ital.v36i4.9959 confidence, that entering a journal, book, or article title into the “search for databases” field would yield a relevant result. a few participants also attempted this with the search box on our research guides (libguides) page, which searches only within the content of the libguides themselves. across all groups, when not starting at the homepage, many participants had difficulty finding books because no clear menu option exists for finding books like it does for articles (our “articles & databases” page). this was difficulty was compounded by many participants struggling to return to the libraries homepage from within the website’s subpages. those participants who were able to navigate back to the homepage were reminded of the primo search box located there and used it to search for books. figure 4. “search for databases” box on the “articles & databases” page. another breakdown was the “help & faq” page (figure 5). participants who turned there for help at any point in the study spent a relatively long time trying to find a usable answer and often ended up more confused than before. in fact, only one in three participants managed to use “help & faq” successfully because the faq consists of many questions with answers on many different pages and subpages. this portion of the website had not been updated in several years and therefore the questions were not listed in order of frequency. information technology and libraries |december 2017 42 figure 5. the answer to the “how do i find books?” faq item leads to several subpages. discussion using the results of the study, we made several recommendations to the libraries’ web advisory committee and administration: (1) display our hours of operation on the homepage; (2) remove the search boxes from the “articles & databases” and “research guides” pages; (3) condense the “help & faq” pages; and (4) create a “find books” option on the homepage. all of these recommendations were taken into account during a recent redesign of the website. we also considered each user group’s performance and its implications for website design as well as instruction and outreach efforts. first, our team suggested that the current day’s hours of operation be featured prominently on the website’s front page. despite “how late is our main library open on a typical monday night?” being one of two tasks that had a 100 percent completion rate, this change is easy to make, adds convenience, and addresses a long-voiced complaint. several participants expressed a desire to see this change implemented. moreover, this is something many of our peer libraries provide on their websites. the team’s next recommendation was to remove the “find databases by title” search box from the “article & databases” page. during the study, participants who had a particular database in mind opted to navigate directly to that database rather than search for it. another such search box exists on the “research guides” page. although most of the participants did not encounter this search box during the study, those that did also mistook it for a general search tool. participants everyone’s invited | azadbakht, blair, and jones 43 https://doi.org/10.6017/ital.v36i4.9959 from all groups, especially undergraduate students, assumed that any search box on the libraries’ website was designed to search for and within resources like article databases and the online catalog, regardless of how the search box was labeled. given our findings, libraries with similar search boxes might also consider removing these from their websites. another recommended change was to condense the “help & faq” section of the website considerably. the “help & faq” section was too large and unwieldy for participants to use successfully without becoming visibly frustrated, defeating its purpose. moreover, google analytics showed that only nine of the more than one hundred “help & faq” pages were used with any regularity. going forward, we will work to identify the roughly ten most important questions to feature in this section. the final major recommendation was to consider adding a top-level menu item called “find books” that would provide users with a means to escape the depths of the site and direct them to primo or the classic catalog. when participants would get stuck on the book-finding task, they looked for a parallel to the “articles & databases” menu option. a “getting started” page or libguide could take this idea a step further by also including brief, straightforward instructions on finding articles and journals by title. in effect, this option would be another way to condense and reinvent some of the topics originally addressed in the “help & faq” pages. comparing each user group’s average performance helped illuminate the strengths and weaknesses of the website’s design. we suspect that graduate students were the fastest and nearly most successful group because they are early in their academic careers and doing a great deal of their own research (as compared to faculty). many of them are also responsible for teaching introductory courses and are working closely with first-year students who are just learning how to do research. faculty, because their research tends to be on narrower topics, were familiar with the specific resources and tools they use in their work but were less able to efficiently navigate the parts of the website with which they have less experience. moreover, individual faculty varied widely in their comfort level with technology, and this affected their ability to complete certain tasks. conclusion the results of our website usability study echo those found elsewhere in the literature. students approach library search interfaces as if they were google and generally conduct very simple searches. without knowledge of the libraries’ digital environment and without the research skills library employees possess, undergraduates in our study tended to favor the most direct route to the answer—if they could identify it. this group had the most trouble with library and academic terminology or concepts like the difference between an article and a journal. though not as quick as the graduate students, undergraduates completed tasks swiftly, mainly becau se of their reliance on the primo discovery tool. however, undergraduate students were less able to recover from missteps; more of them confused the “find databases by title” search tool for an article search tool than participants from any other group. since undergraduates compose the bulk of our user information technology and libraries |december 2017 44 base and are the least experienced researchers, we decided to focus our redesign on solutions that will help them use the website more easily. although all of the library employees in our study work in public-facing roles, not all of them provide regular research help or teach information literacy. since most of them are very familiar with our website and online resources, they approached the tasks more methodically and thoroughly than other participants. library employees tended to choose the search strategy or path to discovery that would yield the highest-quality result or they would demonstrate multiple ways of completing a given task, including any necessary workarounds. the inclusion of library employees yielded the most powerful tool in our research team’s arsenal. holding this group’s “correct” methods side-by-side to equally valid methods of discovery helped shake loose rigid thinking, and the fact that some library employees were unable to complete certain tasks shocked all parties in attendance when we presented our findings to stakeholders. any potential argument that student, faculty, and staff missteps were the result of improper instruction and not of a usability issue was countered by evidence that the same missteps were sometimes made by library staff. not only was this an eye-opening revelation to our entire staff, it served as the evidence our team needed to break through entrenched resistance to making any changes. we were met with almost instant, even enthusiastic, buy-in to our redesign recommendations from the libraries’ administration. therefore, we highly recommend that other academic libraries consider including library staff as participants in their website usability studies. references 1 barbara a. blummer, “a literature review of academic library web page studies,” journal of web librarianship 1, no. 1 (2007): 45–64,

m. g. fancher beeler: cuyahoga county public library, and a. reisman and b. v. dean: case western reserve university, department of operations research. this paper describes a pmfect designed to impmve services to libmry users by solving, through the application of operations research methods, a complex problem of delivery of library materials in an urban, multisystem library service region. unique features, methodology, results, and limitations are discussed. introduction when one realizes that 113 of the major libraries in the country carry 75 percent of the estimated total cost of interlibrary loan per year of 16 million dollars, the importance of greater utilization of local resources is obvious.1 during the planning of the implementation of a closed-circuit teletype communications network ( twp) among libraries in greater cleveland in 1968, it became apparent that improved communications answer only a part of the problem of shared access to library materials. in fact, user frustration is often increased by the inability of a library to provide quickly the materials that it has informed a library user are available in another library in the region. effective delivet·y of materials is an essential component of a successful library network, with efficiency a highly desirable characteristic. in late summer of 1968, representatives of several libraries in cleveland met as an ad hoc committee to discuss approaches to the solution of the problem: how to make the total resources of all types of libraries in greater cleveland more accessible to all, hopefully, by providing daily delivery service among all libraries. members of the committee agreed that the complexity of the problem required more than the pragmatic approach. discussions with members of the department of operations research at case western reserve university led to the preparation of a proposal: "an operations research study and design of an optimal distribution network for selected public, academic, and special libraries in greater 276 journal of libmry automation vol. 7 i 4 december 197 4 cleveland." prior to the preparation of the proposal, a literature search and inquiries to major cooperative networks had indicated that nowhere had the operations research approach been utilized to improve a library delivery system of the scope of that with which we were dealing. 2 after a year's delay, the proposal became a project sponsored by the library council of greater cleveland 4 and funded through the state library of ohio under title iii of the library services and construction act. a task force of librarians and operations researchers began work in the summer of 1970: the official project was completed in september 1972.3 the strategy chosen for this project was to delineate objectives, describe the present system iri detail, and design an improved system ·based on the existing system. methodology specifically, the generalized statement of the problem as defined by the project team was to 1. determine optimized delivery frequencies, schedules, and · routes which maintain the present distribution system's effectiveness and reduce present costs, 2. determine the optimal delivery frequencies, schedules, and routes which maximize the distribution system's effectiveness without increasing costs, and 3. evaluate alternative configurations of distribution systems in consideration of the network of library demands and geographical locations of garages, vehicles, and drivers. next the task force undertook, by means of questionnaires, data collection forms, and site visitations, the difficult and time-consuming task of describing a system the magnitude and complexity of which is apparent from figure 1. the result was a report, systems description i. we consider systems description i a major accomplishment, bringing together for the first time specific details of many of the operations of the libraries and library systems in cleveland and giving basic information on the who, how, and how much of the delivery subsystem. this subsystem was formally defined as comprising ( 1) personnel, ( 2) vehicles, ( 3) facilities, ( 4) supplies, and ( 5) funds, together with the schedules and routes involved in the physical movement of library materials. in cleveland, this consisted of ( 1) drivers, custodial staff (in smaller libraries), student couriers (in academic libraries); ( 2) trucks owned and operated by the cuyahoga county public library and the cleve1and public library, commercial vehicles and " the library council of greater cleveland is comprised of the directors of the following libraries: case western reserve university, cleveland heights-university heights public libra1y, cleveland public library, cleveland state university, cuyahoga county public library, east cleveland public librmy, euclid public library, lakewood pubic library, porter public library, rocky river public library, shaker

.067 .065 .058 .021 the magnitude of the volume of materials involved is clear from the fact that on a single day each truck averages a delivery and/or pick up of 43 telescopes, 114 packages, 49 bindery boxes, and 36 audiovisual items. annually, 5 million volumes of interand intralibrary loans and reciprocal returns are transported among the libraries. for each of the libraries, the amount of materials originating for shipment was defined as the "de278 journal of library automation vol. 7/4 december 1974 mand" which that library placed on the delivery system. although most of the delivery stop services in the cleveland area are libraries, some are not, e.g., hospitals, post offices, boards of education, and schools. we decided to designate delivery points as "nodes." a library node is characterized by the following attributes: 1. it receives delivery on a continuing basis. 2. it is located within the boundaries of a specified geographic area at a fixed site. 3. it has an expressed need for library materials and/or is a source of materials needed elsewhere. 4. it contains library facilities and/or assigns a person to library service. 5. it has a formal (contractual, political, administrative, etc.) or an informal agreement with other nodes and/or library systems. seven hundred sixty-two nodes were identified in the systems description, including over 700 libraries with total collections of over 8 million books, 27,000 periodical subscriptions, and 200,000 technical reports. each of the nodes was coded to provide a convenient notation for computer processing. figure 2 displays a section of a computer-generated map. as indicated earlier, the discipline used in this study was that of operations research. operations research is the application of mathematical and

delivery. engineering techniques to the solution of management and systems problems, generally but not necessarily with the use of the computer. the operations research approach requires a valid unit of measurement. if an existing system is to be evaluated for comparison with alternative systems other than subjectively, some quantitative basis must be derived. we believe that one of the most important products of this project was the development of a measure of effectiveness, or "objective function." this measure was a composite of numerical values (weights ) assigned to the types of materials to be delivered, as shown in table 1; the frequency of delivery within a week; timeliness value (utility), as shown in figures 3 and 4; and the number of units to be delivered. to illustrate: ten interlibrary loan items (a weight of .135) delivered in less than one day (a utility of 1) have an effectiveness value of 13.5. on the other hand, ten items delivered in five days (a utility of .5) have 'an effectiveness value of 0.5 x .135 x 10 = 6.75. a system designed to accomplish the latter would have 50 percent less effectiveness than a system that accomplished the former. no librarian needs to be told that it is generally more important to deliver interlibrary loans promptly than it is to deliver supplies. but in order to use operations research methods, quantitative values, as we have said, are required. the values shown in table 1 and the sensitivity to timeliness of delivery, i.e., figures 3 and 4, were established by the use of a technique 280 journal of

( i 5 ) newly processed intra library ( 1 7 ) correspondence (i 1 ) intra library loans (i 4) known as the delphi method. our application of the method in this project has been described elsewhere. 4 essentially the method seeks out a consensus from a panel of knowledgeable people, in this case experts from academic, school, special, and public libraries, and a trustee. the methodology has three characteristics: anonymity, controlled feedback, and statistical group response. anonymity is used to minimize the linpacts of dominant individuals in the panel. this is achieved by eliciting separate and individual responses to previously prepared questions. in this case, the responses were made in writing on preprinted forms. controlled feedback reduces the variance in parameter estimates. after the first and all remaining rounds, the results of the previous round are fed back to the panel in a summarized form showing the vote distribution along with various justifications for votes after the second round. since the panel is asked to reevaluate their position based on the feedback provided, but with no particular attempt to anive at unanimity, the spread of votes will usually be much smaller after several rounds than during the earlier rounds. this is known as statistical group response. in each case consensus was reached within five rounds. in addition to the need for evaluating system effectiveness in relation to service, there is the need to relate effectiveness to costs. systems description i provided the data on all fixed and variable costs of the existing system. because of the prevailing use in libraries of line accounting, all the improved delivery/herling, et al. 281 300 --~9---r.r---€>~· ~----;:'\..jo;0j..--hdq 0 0 250 200 "' ~ 150 ..., h ::0: ~ legei:ijl !;! 100

written to emulate the system, introducing, however, the measure of effectiveness to make it possible to establish values representing the existing level of performance. entered in the program were 1. the nodes, 2. demand and frequency of delivery at each node, 3. geographic coordinates of each node, 4. unit costs, and 5. weights and utilities for each type of material. the program was run to compute, for each driver, the costs, distances traveled, volume delivered, time utilization, the effectiveness as discussed earlier, and then the cost/effectiveness ratios. figures 5 through 10 show

drivers, then data for several weeks for different drivers. total effectiveness of the existing system, as measured by the sum of the multiples of the importance of each material type (weight), their timeliness values (utilities), and total amounts of materials delivered, ranged from 8,110 to 9,950. costs ranged from $3,801 to $3,934 per week. a second program incorporating the tools of operations research known as simulation and optimization was then used to design an improved system. this program (simopt) included a routing algorithm (set of instructions to the computer) to determine the best routes for each of the drivers on a daily basis. figure 11 describes the basic logic of this program. the procedures to operate the methodology require the following steps (see figure 11) : 1. based on the library hierarchy, contractual arrangements, or any ex~ traneous but agreed-upon reasons, the librarians assign frequencies of delivery to each group of or individual nodes. 2. using the maps (figure 2) and other information, librarians group nodes and assign them to a driver along with the frequency as de284 journal of library automation vol. 7/4 december 1974 200 '"' 150 "' "' ~ "' p., §

caused a limitation on the time that could be devoted to study of the deimproved delivetyjherling, et al. 287 300 0 250 "' "' ~ 200 "' legend :;j [;:' 0 hdq h a ---a "' "' 0 ----b "' 0 :> 150 0 ---c ~

1 cles and large trucks would produce a more costeffective system. acceptance of the location of facilities such as garages as fixed was a further limiting factor: their relocation might have a significant effect. finally, the method of approach in concert with the realities of library budgets ruled out the design of an ideal system unrelated to the existing system. · enough has been written recently to denigrate the usefulness of the computer in library applications. nevertheless, we must acknowledge that a greater amount of human intervention than anticipated was employed as a corrective in the generation of computer-produced routes and must also be used for their implementation. consider: each of 700 geographical locations is a potential successor in a route to any other of the remaining 699. to process these for computer routing would require obtaining nearly 500,000 pairs of geographical coordinates, their keypunching, and verifying. by human selection from a map, reasonable sets of contiguous nodes were fed into the computer; the pairs of geographical coordinates were thus reduced to the not unmanageable number of 2,500 . to 6,400 pairs. further, once computer

methodology are of value to the library community, not only in application to library delivery systems but also in application to a multitude of library service problems, particularly those involving several libraries or library systems, albeit because of changes in top administrative positions within the key library systems the results of this study are still awaiting implementation. improved

abstract the purpose of this article is to demonstrate a practical use case of pdf/a for digitization of text documents following fadgi’s recommendation of using pdf/a as a preferred digitization file format. the authors demonstrate how to convert and combine tiffs with associated metadata into a single pdf/a-2b file for a document. using real-life examples and open source software, the authors show readers how to convert tiff images, extract associated metadata and international color consortium (icc) profiles, and validate against the newly released pdf/a validator. the generated pdf/a file is a self-contained and self-described container that accommodates all the data from digitization of textual materials, including page-level metadata and icc profiles. providing theoretical analysis and empirical examples, the authors show that pdf/a has many advantages over the traditionally preferred file format, tiff/jpeg2000, for digitization of text documents. background pdf has been primarily used as a file delivery format across many platforms in almost every device since its initial release in 1993. pdf/a was designed to address concerns about long-term preservation of pdf files, but there has been little research and few implementations of this file format. since the first standard (iso 19005 pdf/a-1), published in 2005, some articles discuss the pdf/a family of standards, relevant information, and how to implement pdf/a for born-digital documents.1 there is growing interest in the pdf and pdf/a standards after both the us library of congress and the national archives and records administration (nara) joined the pdf association in 2017. nara joined the pdf association because pdf files are used as electronic documents in every government and business agency. as explained in a blog post, the library of congress joined the pdf association because of the benefits to libraries, including participating in developing pdf standards, promoting best-practice use of pdf, and access to the global expertise in pdf technology.2 few articles, if any, have been published about using this file format for preservation of digitized content. yan han published a related article in 2015 about theoretical research on using pdf/a for text documents.3 in this article, han discussed the shortcomings of the widely used tiff and jpeg2000 as master preservation file formats and proposed using the then-emerging pdf/a as the preferred file format for digitization of text documents. han further analyzed the requirements mailto:yhan@email.arizona.edu mailto:wanxueheng@email.arizona.edu digitization of text documents using pdf/a | han and wan 53 https://doi.org/10.6017/ital.v37i1.9878 of digitization of text documents and discussed the advantages of pdf/a over tiff and jpeg2000. these benefits include platform independence, smaller file size, better compression algorithms, and metadata encoding. in addition, the file format reduces workload and simplifies postdigitization processing such as quality control, adding and updating missing pages, and creating new metadata and ocr data for discovery and digital preservation. as a result, pdf/a can be used in every phase of a digital object in an open archival information system (oais)—for example, a submission information package (sip), archive information package (aip), and dissemination information package (dip). in summary, a pdf/a file can be a structured, self-contained, and selfdescribed container allowing a simpler one-to-one relationship between an original physical document and its digital surrogate. in september 2016, the federal agencies digital guidelines initiative (fadgi) released its latest guidelines for digitization related to raster images: technical guidelines for digitizing heritage materials.4 the de-facto best practices for digitization, these guidelines provide federal agencies guidance and have been used in many cultural heritage institutions. both the pdf association and the authors welcomed the recognition of pdf/a as the preferred master file format for digitization of text documents such as unbound documents, bound volumes, and newspapers.5 goals and tasks since han has previously provided theoretical methods of coding raster images, metadata, and related information in pdf/a, the goals of this article are threefold: 1. present real-life experience of converting tiffs/jpeg2000s to pdf/a and back, along with image metadata 2. test open source libraries to create and manipulate images, image metadata, and pdf/a 3. validate generated pdf/as with the first legitimate validator for pdf/a validation the tasks included the following: ● convert all the master files in tiffs/jpeg2000 from digitization of text documents into single pdf/a files losslessly. one document, one pdf/a file. ● evaluate and extract metadata from each tiff/jpeg2000 image and encode it along with its image when creating the corresponding pdf/a file. ● demonstrate the runtimes of the above tasks for feasibility evaluation. ● validate the pdf/a files against the newly released open source pdf/a validator verapdf. ● extract each digital image from the pdf/a file back to its original master image files along with associated metadata. ● verify the extracted image files in the back-and-forth conversion process against the original master image files choices of pdf/a standards and conformance level this article demonstrates using pdf/a-2b as a self-contained self-describing file format. currently, there are three related pdf/a standards (pdf/a-1, pdf/a-2, and pdf/a-3), each with information technology and libraries | march 2018 54 three conformance levels (a, b, and u). the reasons for choosing pdf/a-2 (instead of pdf/a-1 or pdf/a-3) are the following: ● pdf/a-1 is based on pdf 1.4. in this standard, images coded in pdf/a-1 cannot use jpeg2000 compression (named in pdf/a as jpxdecode). one can still convert tiffs to pdf/a-1 using other lossless compression methods such as lzw. however, the spacesaving benefits of jpeg2000 compression over other methods would not be utilized. ● pdf/a-2 and pdf/a-3 are based on pdf 1.7. one significant feature of pdf 1.7 is that it supports jpeg2000 compression, which saves 40–60 percent of space for raster images compared to uncompressed tiffs. ● pdf/a-3 has one major feature that pdf/a-2 does not have, which is to allow arbitrary files to be embedded within the pdf file. in this case, there is no file to be embedded. the authors chose conformance level b for simplicity. ● b is basic conformance, which requires only necessary components (e.g., all fonts embedded in the pdf) for reproduction of a document’s visual appearance. ● a is accessible conformance, which means b conformance level plus additional accessibility (structural and semantic features such as document structure). one can add tags to convert pdf/2b to pdf/2a. ● u represents a conformance level with the additional requirement that all text in the document have unicode equivalents. this article does not cover any post-processing of additional manual or computational features such as adding ocr text to the generated pdf/a files. these features do not help faithfully capture the look and feel of original pages in digitization, and they can be added or updated later without any loss of information. in addition, ocr results rely on the availability of ocr engines for the document’s language, and results can vary between different ocr engines over time. ocr technology is getting better and will produce better results in the future. for example, current ocr technology for english gives very reliable (more than 90 percent) accuracy. in comparison, traditional chinese manuscripts and pashto/persian give unacceptably low accuracy (less than 60 percent). the cutting edge on ocr engines has started to utilize artificial intelligence networks, and the authors believe that a breakthrough will happen soon. data source the university of arizona libraries (ual) and afghanistan center at kabul university (acku) have been partnering to digitize and preserve acku’s permanent collection held in kabul. this collaborative project created the largest afghan digital repository in the world. currently the afghan digital repository (http://www.afghandata.org) contains more than fifteen thousand titles and 1.6 million pages of documents. digitization of these text documents follows the previous version of the fadgi guideline, which recommended scanning each page of a text document into a separate tiff file as the master file. these tiffs were organized by directories in a file system, where each directory represents a corresponding document containing all the scanned pages of this title. an example of the directory structure can be found in han’s article. http://www.afghandata.org/ digitization of text documents using pdf/a | han and wan 55 https://doi.org/10.6017/ital.v37i1.9878 pdf/a and image manipulation tools there are a few open source and proprietary pdf software development kits (sdk). adobe pdf library and foxit sdk are the most well-known commercial tools to manipulate pdfs. to show readers that they can manipulate and generate pdf/a documents themselves, open source software, rather than commercial tools, was used. currently, only a very limited number of open source pdf sdks are available, including itext and pdfbox. itext was chosen because it has g ood documentation and provides a well-built set of apis to support almost all the pdf and pdf/a features. initially written by bruno lowagie (who was in the iso pdf standard working group) in 1998 as an in-house project, lowagie later started up his own company, itext, and published itext in action with many code examples.6 moreover, itext has java and c# coding options with good code documentation. it is worth mentioning that itext has different versions. the author used itext 5.5.10 and 5.4.4. using an older version in our implementation generated a non-compatible pdf/a file because the it was not aligned with the pdf/a standard.7 for image processing, there were a few popular open source options, including imagemagick and gimp. imagemagick was chosen because of its popularity, stability, and cross-platform implementation. our implementation identified one issue with imagemagick: the current version (7.0.4) could not retrieve all the metadata from tiff files as it did not extract certain information such as the image file directory and color profile. these metadata are critical because they are part of the original data from digitization. unfortunately, the author observed that some image editors were unable to preserve all the metadata from the image files during the conversion process. hart and de varies used case studies to show the vulnerability of metadata, demonstrating metadata elements in a digital object can be lost and corrupted by use or conversion of a file to another format. they suggested that action is needed to ensure proper metadata creation and preservation so that all types of metadata must be captured and preserved to achieve the most authentic, consistent, and complete digital preservation for future use.8 metadata extraction tools and color profiles as we digitize physical documents and manipulate images, color management is important. the goal of color management is to obtain a controlled conversion between the color representations of various devices such as image scanners, digital cameras, and monitors. a color profile is a set of data that control input and output of a color space. the international color consortium (icc) standards and profiles were created to bring various manufacturers together because embedding color profiles into images is one of the most important color management solutions. image formats such as tiff and jpeg2000 and document formats such as pdf may contain embedded color profiles. the authors identified a few open source tools to extract tiff metadata, includin g exiftool, exiv2, and tiffinfo. exiftool is an open source tool for reading, writing, and manipulating metadata of media files. exiv2 is another free metadata tool supporting different image formats. the tiffinfo program is widely used in the linux platform, but it has not been updated for at least ten years. our implementations showed that exiftool was the one that most easily extracted the full icc profiles and other metadata from tiff and jpeg2000 files. imagemagick and other image processing software were examined in van der knijff’s article discussing jpeg2000 for long-term preservation.9 he found that icc profiles were lost in imagemagick. our implementation has information technology and libraries | march 2018 56 showed the current version of imagemagick has fixed this issue. a metadata sample can be found in appendix a. implementation converting and ordering tiffs into a single pdf/a-2 file when ordering and combining all individual tiffs of a document into a single pdf/a-2b file, the authors intended to preserve all information from the tiffs, including raster image data streams and metadata stored in each tiff’s header. the raster image data streams are the main images reflecting the original look and feel of these pages, while the metadata (including technical and administrative metadata such as bitspersample, datetime, and make/model/software) tells us important digitization and provenance information. both are critical for delivery and digital preservation. the tiff images were first converted to jpeg2000 with lossless compression using the open source imagemagick software. our tests of imagemagick demonstrated that it can handle different color profiles and will convert images correctly if the original tiff comes with a color profile. this gave us confidence that past concerns about jpeg2000 and imagemagick had been resolved. these images were then properly sorted into their original order and combined into a single pdf/a-2 file. an alternative is to directly code tiff’s image data stream into a pdf/a file, but this approach would miss one benefit of pdf/a-2: tremendous file size reduction with jpeg2000. the following is the pseudocode of ordering and combining all the tiffs in a text document into a single pdf/a2 file. createpdfa2(queue tifflist) { create an empty queue xmlq; create an empty queue jp2q; /* tifffilelist is pre-sorted queue based on the original order */ /* convert each tiff to jpeg2000 losslessly, then add each jpeg2000 and its metadata into a queue */ while (tifflist is not empty) { string tifffilepath = tifflist.dequeue(); string xmlfilepath = tiff metadata extracted using exiftool; xmlq.enqueue(xmlfilepath); string jp2filepath = jpeg2000 file location from tiff converted by imagemagick; jp2q.enqueue(jp2filepath); } /* convert each image’s metadata to xmp, add each jpeg2000 and its metadata into the pdf/a-2 file based on its original order */ document pdf2b = new document(); /* create pdf/a-2b conformance level */ pdfawriter writer = pdfawriter.getinstance(doc, new fileoutputstream(pdfafilepath),pdfaconformacelevel.pdf_a_2b); writer.createxmpmetadata(); //create root xmp digitization of text documents using pdf/a | han and wan 57 https://doi.org/10.6017/ital.v37i1.9878 pdf2b.open(); while(jp2q is not empty){ image jp2 = image.getinstance(jp2q.dequeue()); rectangle size = new rectangle(jp2.getwidth(), jp2.getheight()); //pdf page size setting pdf2b.setpagesize(size); pdf2b.newpage(); // create a new page for a new image byte[] bytearr = xmpmanipulation(xmlq.dequeue()); // convert original metadata based on the xmp standard writer .setpagexmpmetadata(bytearr); pdf2b.add(jp2); } pdf2b.close(); } converting pdf/a-2 files back to tiffs and jpeg2000s to ensure that we can extract raster images from the newly created pdf/a-2 file, the authors also wrote code to convert a pdf/a-2 file back to the original tiff or jpeg2000 format. this implementation was a reverse process of the above operation. once the reverse conversion process was completed, the authors verified that the image files created from the pdf/a-2 file were the same as before the conversion to pdf/a-2. note that we generated md5 checksums to verify image data streams. images data streams are the same, but metadata location can be varied because of inconsistent tiff tags used over the years. when converting one tiff to another tiff, imagemagick has its implementation of metadata tags. the code can be found in appendix b. pdf/a validation pdf/a is one of the most recognized digital preservation formats, specially designed for long -term preservation and access. however, no commonly accepted pdf/a validator was available in the past, although several commercial and open source pdf preflight and validation engines (e.g., acrobat) were available. validating a pdf/a against the pdf/a standards is a challenging task for a few reasons, including the complexity of the pdf and pdf/a formats. the pdf association and the open preservation foundation recognized the need and started a project to develop an open source pdf/a validator and build a maintenance community. their result, verapdf, is an open source validator designed for all pdf/a parts and conformance levels. released in january 2017, the goal of verapdf is to become the commonly accepted pdf/a validator. 10 our generated pdf/as have been validated with verapdf 1.4 and adobe acrobat pro dc preflight. both products validated the pdf/a-2b files as fully compatible. our implementations showed that verapdf 1.4 verified more cases than acrobat dc preflight. figure 1 shows a pdf file structure and its metadata. information technology and libraries | march 2018 58 figure 1. a pdf object tree with root-level metadata. runtime and conclusion the time complexity of our code is o(log n) because of the sorting algorithms used. tiffs were first converted to jpeg2000. when jpeg2000 images are added to a pdf/a-2 file, no further image manipulation is required because the generated pdf/a-2 uses jpeg2000 directly (in other words, it uses the jpxdecode filter). tables 1 and 2 show the performance comparison running in our computer hardware and

converting a tiff to a jpeg2000 using imagemagick (see figure 2); (b) the average runtime of converting a tiff has a constant positive relationship with the file’s size (see figure 2); (c) in information technology and libraries | march 2018 60 comparison, the runtime of converting a color tiff is significantly higher than that of converting a greyscale tiff (see figure 2); and (d) it is feasible in terms of time and resources to convert existing master images of digital document collections to pdf/a-2b. for example, the runtime of 1 tb of conversion of color tiffs will be 552,831 seconds (153.5 hours; 6.398 days) using the above hardware. the authors have already processed more than 600,000 tiffs using this method. the authors conclude that using pdf/a gives institutions advantages of the newly preferred master file format for digitization of text documents over tiff/jpeg2000. the above implementation demonstrates the ease, the reasonable runtime, and the availability of open source software to perform such conversions. from both the theoretical analysis and empirical evidences, the authors show that pdf/a has advantages over the traditional preferred file format tiff for digitization of text documents. following best practice, a pdf/a file can be a selfcontained and self-described container that accommodates all the data from digitization of textual materials, including page-level metadata and icc profiles. summary the goal of this article is to demonstrate empirical evidences of using pdf/a for digitization of text document. the authors evaluated and used multiple open source software programs for processing raster images, extracting image metadata, and generating pdf/a files. these pdf/a files were validated using the up-to-date pdf/a validators verapdf and acrobat preflight. the authors also calculated the time complexity of the program and measured the total runtime in multiple testing cases. most of the runtime was spent on image conversions from tiff to jpeg2000. the creation of the pdf/a-2b file with associated page-level metadata accounted for less than 5 percent of the total runtime. runtime of conversion of a color tiff was much higher than that of a greyscale one. our theoretical analysis and empirical examples show that using pdf/a-2 presents many advantages over the traditional preferred file format (tiff/jpeg2000) for digitization of text documents. digitization of text documents using pdf/a | han and wan 61 https://doi.org/10.6017/ital.v37i1.9878 figure 2. file size, greyscale and color tiffs

m;depalo, lisa information technology and libraries; mar 2000; 19, 1; proquest pg. 11 the internet as a source of academic research information: harry m. kibirige and lisa depalo findings of two pilot studies as a source of serious subject-oriented information, the internet has been a powerful feature in the information arena since its inception in the last quarter of the twentieth century. it was, however, initially restricted to government contractors or major research universities operating under the aegis of the advanced research projects network (arpanet).1 in the 1990s, the content and use of the internet was expanded to include mundane subjects covered in business, industry, education, government, entertainment, and a host of other areas. it has become a magnanimous network of networks the measurement of whose size, impact, and content often elude serious scholarly effort.2 opening the internet to common usage literally opened the flood gates of what has come to be known as the information superhighway. currently, there is virtually no subject that cannot be found on the internet in one form or another. t here is both hype and reality as to what the internet can generate in terms of substantive information. in their daily pursuits of information, information professionals as well as end-users of information are challenged with regard to what their expectations are and what actually is delivered in terms of tangible information products and services on the net. academic users are a special breed in that both faculty and students have specific topics covered in their courses of study or faculty research agendas for which they need information. the use of electronic resources found on and off the internet is becoming increasingly vital for education and training in academic environments.3 five basic elements often are required in the electronic resources that academic information seekers desire: accessibility, timeliness, readability, relevance, and authority. the internet excels in the first three, but depending on how and from where the information is gathered, it may not be so reliable with regard to the last two elements. the two pilot studies discussed in this article involved four academic institutions and were conducted by the researchers with approximately twelve months apart. one covering two institutions was done in the fall of 1997. it was replicated covering another two institutions in the spring of 1999. the main goal of the studies was to investigate how academic users perceive search engines and subject-oriented databases as sources of topical information . the basic underlying question was, "when faced with a topical subject, what is the users' predominant recourse, online databases (which may include cd-rom, or dvd databases) or search engines?" our results indicated that there is predominant preference for search engines for the group taken as a whole. further analysis using nonparametric correlation coefficientskendall's tau_b and spearman's rho-however, indicated that those who use the internet monthly or weekly had high correlations with online databases as their preferred predominant information sources . on the other hand, daily users tended to have high correlations with search engines as preferred predominant information sources . i information seeking behavior of academic users over the years, several studies have been conducted on how users seek and find information relevant to their needs . for the purposes of our analysis three categories will be used: the undergraduate, the graduate, and the post-doctoral research faculty user. while the levels of how the needed information may be articulated and packaged may be different , the five basic required elements in the electronic information resources needed by academics, already identified, remain the same. the internet has, however, added another dimension to the information-seeking behavior of all academics in that much of the needed information, if and when found, has a higher chance of appearing as full text (sometimes defined as viewdata) on the internet. 4 with viewdata the end user has the ultimate in information seeking and acquisition in that he or she will get text, images, and sound in one, two, or more resources on the net. the process also may be accomplished in one sitting or search session on the computer terminal. the internet thus may be more likely to generate viewdata in contrast to conventional databases , which have for a long time been associated with the less desirable citations. in many instances and with a little persistence, it can provide the analogy of "one stop shopping" whereby a user can get viewdata needed for a topic. this may explain the tendency to try the internet first as a potential information source even for experienced searchers. to be effective, such searching needs experience and a lot of patience while sifting through pages of useless verbiage, as the information sources often are garnered from several sites. categories of academic users have varying levels of expertise in information seeking and harry m. klblrlge is associate professor at queens college, city university of new york, and lisa depalo is assistant professor at college of staten island, city university of new york. the internet as a source of academic resource information i kibirigie and depalo 11 reproduced with permission of the copyright owner. further reproduction prohibited without permission. have different characteristics in their information-seeking behavior. undergraduate users undergraduates are at the lowest point on the totem pole with regard to expertise in information seeking at any academic institution. there is more to the information needs of undergraduate students than can be revealed during the reference interview process. there are the pervading needs that the information age has created, which can be met only by those who possess critical thinking skills. critical thinking skills are imperative to much more than completing college-level assignments-they are also imperative to surviving in the job market once students graduate. this premise has been set forth in the 1992 united states government report from the department of labor and the secretary's commission on achieving necessary skills (scans) entitled skills and tasks for jobs: a scans report for america 2000. this report defined two types of skills needed to excel in the workplace and labeled them as competencies and foundations. effective reference and instruction services can help students develop the critical thinking skills needed to meet the information competency, in particular, since it pertains to one who "acquires and evaluates information, organizes and maintains information, interprets and communicates information, and uses computers to process information." 5 acquiring and evaluating information can be particularly difficult for undergraduates in the information age since one is bombarded with data in print and electronic formats. one can easily determine the reliability of print sources by looking at the name of the author, editor, or publisher. however, the internet has become a popular choice for students who need to do research. it has gained the reputation for providing all that one needs right at one's fingertips. the problem is that one cannot readily discern what is reliable and what is not without some instruction. it may be argued that the undergraduates' information seeking is somewhat eased by the general guides they get from the faculty in the classroom. there is the general professorial lecture which outlines the topics to be covered during the course, as well as associated relevant readings used to broaden the subjects covered. in addition, there is the text book which elaborates on material covered in class. finally, there are journal articles and other information sources which ordinarily are placed on reserve. as far as subject content covered in class lectures and discussion is concerned, information is usually well organized and accessible. at that level information seeking is minimal and often guided by the dictates of the professor. but then enters the term paper and the whole student peace of mind with regard to information gathering habits is disturbed. the term paper brings many unknowns to the undergraduate. the magnitude of the subject to be covered is initially fuzzy. the resources needed to get background as well as specific information are also fuzzy. furthermore, even when the resources are a little clear, sifting through them and making rational selection of relevant material may be problematic. the whole academic exercise entails learning and using new information tools, many of which were not covered in high school. computers and other electronic equipment have accentuated the undergraduates' mesmerization process in their information-seeking effort. a trait that most undergraduates exhibit in their information-seeking behavior is approaching the reference librarian for suggestions of leads to information sources needed for the term paper topic. they also may request the librarian to evaluate the sources as to their relevance, and sometimes even ask him or her to fetch the actual material needed. 6 with the advent of the internet and other electronic resources online or otherwise, (e.g., dialog, lexis-nexis, cd-roms, dvd, and tapes), the undergraduate may go directly to the internet terminal and thus skip the librarians' counsel and hand-holding which used to be vital for accessing the printed material. unless the undergraduate student is well-groomed in searching the internet, this relatively new tendency to act independently of the information professional may result in hours of useless roaming on the net with little relevant information retrieved. the graduate user in their study of business students, atkinson and figueroa found that graduates reported fewer hours spent in the library than undergraduates.7 the researchers did not attempt to explain why that was so. perhaps because of their search skills, graduates do more focused information seeking and do not waste much of their time browsing and floundering in the unknown information abyss within the library. the researchers reported an equal interest in searching internet resources and online databases (e.g., lexis-nexis, dow jones, and abi/inform), among graduates and undergraduates. however, their research was done at the end of 1995 and beginning of 1996, before the proliferation of search engines on the internet. as an information searcher the graduate is more sophisticated compared with the undergraduate. subject coverage is usually more clearly defined in many of the assignments encountered. he or she has gone through most of the pitfalls of the undergraduate experience and can select a subject and research it relatively well. most likely due to the nature of their assignments, undergraduates' information needs may be satisfied by simple information systems that allow users to browse. their searches also tend to be less exhaustive than graduates. on the other hand, graduates are faced with relatively 12 information technology and libraries i march 2000 reproduced with permission of the copyright owner. further reproduction prohibited without permission. narrower subjects and prefer to conduct more comprehensive searches. 8 the post-doctoral researcher-faculty faculty have mastered the art of getting relevant information. many belong to the informal invisible college and attend professional conferences, both of which are used to get information for teaching and research. hart's study found that formal sources, which may be found in the personal and college or university library, are more important in the faculty's information-seeking effort than informal ones. 9 according to hart, this informationseeking characteristic would be applicable to printed and electronic resources found on the internet. although our research did not specifically test it, online databases tend to direct the end user to formalized definitive and tested resources than the internet search engines. this would minimize user search time and maximize relevance of the information needed by the research academic faculty. in other words, while the listserv might be one of the internet substitutes for the invisible college, information found on it would be more acceptable to a research faculty if it directs him or her to reliable and verifiable databases, i.e., information from cendata (u.s. census bureau information database), edgar (u.s. security and exchange database), or dow jones . developments in the electronic resources arena have made many hard copies less popular. subject-oriented databases can be searched either in the library or in faculty offices. curtis et al. researched the information-seeking behavior of health sciences faculty and found a relatively new and growing information-seeking characteristic. according to curtis et al., faculty tend to prefer to search electronic resources from their offices rather than go to the library. 10 that is not surprising, for if a faculty member can access library catalogs and electronic databases, some of which can provide viewdata (full text), it is not necessary for him or her to go to the library for some of the information needed. in addition, if cd-rom databases are on a local area network accessible via the college online catalog, faculty may seldom go to a library whose resources are on the network via a library web site, telnet, or the traditional dial up. i the pilot studies with the general information-seeking behavior of academic users in mind, the researchers decided to investigate the use of search engines for information sources in the academe in the new york metropolitan area. search engines were contrasted to databases which may be url(universal resource locator) accessible online via an internet browser, stand alone on cd-rom, or on cdrom towers linked by a library local area network. in her article on web search engines, schwartz discussed recent studies done on their performance . she pointed out the fact that the end user is not often a participant in such studies .11 although our research was not on evaluation, we deliberately focused on the end user to gather statistics on perception of web search engine utility in internet surfing and information seeking . kassel evaluated search engines indicating their variety and complexity when used to search the internet. 12 other relevant literature indicated the difficulty of navigating the internet for both the information professional and the end user. it also indicated how direct access to databases was a shortcut to retrieving some of the topical information . our periodic observations of internet users revealed heavy use of search engines. we suspected that end users use them to get topical information which might otherwise be easily gotten from online databases. consequently, we thought it necessary to conduct a study on end-user perception . objectives our objectives in embarking on the pilot studies were to: 1. find the frequency of internet use by end users. this would allow us to check whether there is a correlation between frequency of internet use and perception of search engine utility. 2. find the most popular search engine. examining the most popular search engine with respect to indexing policy might indicate whether it would generate more topical subject type of information. 3. gauge the use of online and cd-rom databases in the library. in order to help the end-users' memory as to what databases are involved in the research, common databases were listed on the questionnaire as examples. 4. gauge the use of search engines in libraries and information centers. common search engines likewise were listed to help the end user identify what they were. 5. relate the results to pragmatic library and informa tion-center functioning in providing information . methodology four metropolitan new york academic institutions were selected : borough of manhattan community college; iona college; queens college of the city university of new york; and wagner college. the main criteria for selection was ease of access for the researchers. a composite sample of users was selected from these institutions to participate in the studies. the sample used was dynamic and self-selected in that whoever used the the internet as a source of academic resource information i kibirigie and depalo 13 reproduced with permission of the copyright owner. further

"internet terminal" was a potential research subject. only end users as opposed to information professionals/librarians were used in the study . while subjects sat at the terminal, they were requested to complete the questionnaire and return it to the reference/information desk. simplicity dictated the design of the research and data collection instrument (questionnaire). it was one page, multicolored, and was entitled "internet use questionnaire." we estimated that it would take the subjects four to seven minutes to complete. our assumption daily 46% ivlonthly 9% weekly 45% in designing it to be simple and least time-consuming was that since the subjects were sitting at the terminals, they were time conscious. figure 1. frequency of internet use while subjects were asked to complete the questionnaire, they had the option not to. forty copies of the questionnaire were given to each academic institutional librar y, making a total of 160. useable returns were 155, or 97 percent. in addition to the questionnaire, we conducted exit interviews with some of the subjects who were using the internet terminals after they handed in the completed questionnaires. the purpose of the interviews was to have some idea as to how the users perceived the utility of the internet in getting electronic-based information . four questions were used: 1. how do you find the internet as an information source? 2. did you get what you needed from the internet ? 3. do you have a favorite search engine? 4. is there any point when you would seek the assistance of the reference librarian/information specialist? analysis of the data was done using the spss (statistical package for social science) package. we used descriptive statistics for general group tendencies-frequency of internet use and preferred sources for topical subject search. for inferential statistics we preferred the non-parametric pairwise two-tailed correlation coefficients, kendall's tau_b and spearman's rho statistics . microsoft's excel program package was used to draw some of the illustrations. results the study revealed that an overwhelming majority of subjects (91 percent) use the internet at least once a week (this includes those who use it daily) . an almost equal number (45 percent) use it weekly-(at least once a week); 46 percent use it at least once a day (see figure 1). as figure 2 shows, search engines are the predominant preferred tools for searching topical subjects on the search engine 84% figure 2. preferred sources for subject search online db 16% internet as contrasted to online and cd-rom databases. we used the two-tailed pairwise correlation coefficients to see whether there are correlations between frequency of internet use and tool preferences. as table 1 and table 2 indicate, subjects who used the internet monthly or weekly had high correlations with online databases . daily users, however, tended to have high correlations with search engines as tools to get to topical subject information sources. i interpretations and conclusions search engines certainly provide the most common access points utilized by library /information center users to get to electronic resources on the internet . unfortunately, the average user seems to have the impression that the internet is a be-all and almost a panacea to all information problems. kassel suggests 14 information technology and libraries i march 2000 reproduced with permission of the copyright owner. further reproduction prohibited without permission. the pilot studies do not give correlatlons conclusive answers as to why the daily i seng i m:>nthl y i weekly ondb weekly and monthly internet users correlated with those who use online and cd-rom databases. it might be that they search the internet via search engines as supplements to conventional online sources. alternatively they may search using search engines on an exploratory basis when they begin a relatively new subject. daily users who correlated with search engines might have mistaken the highway function of search spearman's rho daily correlation coeffic ient 1.000 -.544 sig.

reproduced with permission of the copyright owner. further reproduction prohibited without permission. emphasize in their training the proven online databases to which users should go directly, if and when those databases are provided by the library or information center. information professionals have a direct link to providing users with guidance to proven online databases, specifically during course-integrated instruction. education for the end user is paramount to the optimum utilization of electronic information sources. a welldeveloped information resources instruction program is needed in conjunction with the one-on-one instruction that takes place every day at the reference/information desk. such instruction programs must be cumulative, if they are to be effective in an age of burgeoning choices for end users who can more and more often choose to be remote users of information resources. in an academic environment, early intervention at the freshman level is paramount, but also must be pursued in a structured manner at the upper levels. many college and university information resources instruction programs are based on a one-shot, approximately fifty minute session, which often is executed as an orientation to the library /information center. such a method of instruction has no guarantee that there will be further guidance sought, either at the behest of a teaching faculty member in the form of course-integrated instruction, or on an individual level at the reference desk. developing effective ways to integrate information resources instruction into the

letter from the editor: farewell 2020 letter from the editor farewell 2020 kenneth j. varnum information technology and libraries | december 2020 https://doi.org/10.6017/ital.v39i4.13051 i don’t think i’ve ever been so ready to see a year in the rear-view mirror as i am with 2020. this year is one i’d just as soon not repeat, although i nurture a small flame of hope. hope that as a society what we have experienced this year will exert a positive influence on the future. hope that we recall the critical importance of facts and evidence. hope that we don’t drop the effort to be better members of our local, national, and global communities and treat everyone equitably. hope that as a global populace we continue to get into “good trouble” and push back against institutionalized policies and practices of racism and discrimination and strive to be better. despite the myriad challenges this year has brought, it is welcome to see so many libraries continuing to serve their communities, adapting to pandemic restrictions, and providing new and modified access to books and digital information. and equally gratifying, from my perspective as ital’s editor, is that so many library technologists continue to generously share what they have learned through submissions to this journal. along those lines, i’m extending my annual invitation to our public library colleagues to propose a contribution to our quarterly column, “public libraries leading the way.” items in this series highlight a technology-based innovation from a public library perspective. topics we are interested in could include any way that technologies have helped you provide or innovate service to your communities during the pandemic, but could touch on any novel, interesting, or promising use of technology in a public library setting. columns should be in the 1,000-1,500 word range and may include illustrations. these are not intended to be research articles. rather, public libraries leading the way columns are meant to share practical experience with technology development or uses within the library. if you are interested in contributing a column, please submit a brief summary of your idea. wishing you the best for 2021, kenneth j. varnum, editor varnum@umich.edu december 2020 https://ejournals.bc.edu/index.php/ital/pllw

mailto:varnum@umich.edu editorial | truitt 3 marc truitteditorial w elcome to 2009! it has been unseasonably cold in edmonton, with daytime “highs”—i use the term loosely— averaging around -25°c (that’s -13°f, for those of you ital readers living in the states) for much of the last three weeks. factor in wind chill (a given on the canadian prairies), and you can easily subtract another 10°c. as a result, we’ve had more than a few days and nights where the adjusted temperature has been much closer to -40°, which is the same in either celsius or fahrenheit. while my boss and chief librarian is fond of saying that “real canadians don’t even button their shirts until it gets to minus forty,” i’ve yet to observe such a feat of derring-do by anyone at much less than twenty below <grin>. even your editor’s two labrador retrievers—who love cooler weather—are reluctant to go out in such cold, with the result that both humans and pets have all been coping with bouts of cabin fever since before christmas. n so, when is it “too cold” for a server room? why, you may reasonably ask, am i belaboring ital readers with the details of our weather? over the weekend we experienced near-simultaneous failures of both cooling systems in our primary server room (sr1), which meant that nearly all of our library it services, including our opac (which we host for a consortium of twenty area libraries), a separate opac for edmonton public library, our website, and access to licensed e-resources, e-mail, files, and print servers had to be shut down. temperature readings in the room soared from an average of 20–22°c (68–71.5°f) to as much as 37°c (98.6°f) before settling out at around 30°c (86°f). we spent much of the weekend and beginning of this week relocating servers to all manner of places while the cooling system gets fixed. i imagine that next we may move one into each staff person’s under-heated office, where they’ll be able to perform double duty as high-tech foot warmers! all of this happened, of course, while the temperature outside the building hovered between -20° and -25°c. this is not the first time we’ve experienced a failure of our cooling systems during extremely cold weather. last winter we suffered a series of problems with both the systems in sr1 and in our secondary room a few feet away. the issues we had then were not the same as those we’re living through now, but they occurred, as now, at the coldest time of the year. this seeming dichotomy of an overheated server environment in the depths of winter is not a matter of accident or coincidence; indeed, while it may seem counterintuitive, the fact is that many, if not all, of our cooling woes can be traced to the cold outside. the simple explanation is that extreme cold weather stresses and breaks things, including hvac systems. as we’ve tried to analyze this incident, it appears likely that our troubles began when the older of our two systems in sr1 developed a coolant leak at some point after its last preventive maintenance servicing in august. fall was mild here, and we didn’t see the onset of really severe cold weather until early to mid-december. since the older system is mainly intended for failover of the newer one, and since both systems last received routine service recently, it is possible that the leak could have developed at any time since, although my supposition is that it may be itself a result of the cold. in any case, all seemed well because the newer cooling system in sr1 was adequate to mask the failure of the older unit, until it suffered a controller board failure that took it offline last weekend. but, with the failure of the new system on saturday, all it services provided from this room had to be brought down. after a night spent trying to cool the room with fans and a portable cooling unit, we succeeded in bringing the two opacs and other core services back online by sunday, but the coolant leak in the old system was not repaired until midday monday. today is friday, and we’ve limped along all week on about 60 percent of the cooling normally required in sr1. we hope to have the parts to repair the newer cooling system early next week (fingers crossed!). some interesting lessons have emerged from this incident, and while probably not many of you regularly deal with -30°c winters, i think them worth sharing in the hope that they are more generally applicable than our winter extremes are: 1. document your servers and the services that reside on them. we spent entirely too much time in the early hours of this event trying to relate servers and services. we in information technology (it) may think of shutting down or powering up servers “fred,” “wilma,” “betty,” and “barney,” but, in a crisis, what we generally should be thinking of is whether or not we can shut down e-mail, file-and-print services, or the integrated library system (ils) (and, if the latter, whether we shut down just the underlying database server or also the related staff and public services). perhaps your servers have more obvious names than ours, in which case, count yourself fortunate. but ours are not so intuitively named—there is a perfectly good reason for this, by the way—and with distributed applications where the database marc truitt (marc.truitt@ualberta.ca) is associate director, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 4 information technology and libraries | march 2009 may reside here, the application there, and the web front end yet somewhere else, i’d be surprised if your situation isn’t as complex as ours. and bear in mind that documentation of dependencies goes two ways: not only do you want to know that “barney” is hosting the ils’s oracle database, but you also want to know all of the servers that should be brought up for you to offer ils–related services. 2. prioritize your services. if your cooling system (or other critical server-room utility) were suddenly only operating at 50 percent of your normal required capacity, how would you quickly decide which services to shut down and which to leave up? i wrote in this space recently that we’ve been thinking about prioritized services in the context of disaster recovery and business continuity, but this week’s incident tells me that we’re not really there yet. optimally, i think that any senior member of my on-call staff should be empowered in a given critical situation to bring down services on the basis of a predefined set of service priorities. 3. virtualize, virtualize, virtualize. if we are at all typical of large libraries in the association of research libraries (and i think we are), then it will come as no surprise that we seem to add new services with alarming frequency. i suspect that, as with most places, we tend to try and keep things simple at the server end by hosting new services on separate, dedicated servers. the resulting proliferation of new servers has led to ever-greater strains on power, cooling, and network infrastructures in a facility that was significantly renovated less than two years ago. and i don’t see any near-term likelihood that this will change. we are, consequently, in the very early days of investigating virtualization technology as a means of reducing the number of physical boxes and making much better use of the resources—especially processor and ram— available to current-generation hardware. i’m hoping that someone among our readership is farther along this path than we and will consider submitting to ital a “how we done it” on virtualization in the library server room very soon! 4. sometimes low-tech solutions work . . . no one here has failed to observe the irony of an overheated server room when the temperature just steps away is 30° below. our first thought was how simple and elegant a solution it would be to install ducting, an intake fan, and a damper to the outside of the building. then, the next time our cooling failed in the depths of winter, voila!, we could solve the problem with a mere turn of the damper control. 5. . . . and sometimes they don’t. not quite, it seems. when asked, our university facilities experts told us that an even greater irony than the one we currently have would be the requirement for can$100,000 in equipment to heat that -30°c outside air to around freezing so that we wouldn’t freeze pipes and other indoor essentials if we were to adopt the “low-tech” approach and rely on mother nature. oh, well . . . n in memoriam most of the snail mail i receive as editor consists of advertisements and press releases from various firms providing it and other services to libraries. but a few months ago a thin, hand-addressed envelope, postmarked pittsburgh with no return address, landed on my desk. inside were two slips of paper clipped from a recent issue of ital and taped together. on one was my name and address; the other was a mailing label for jean a. guasco of pittsburgh, an ala life member and ital subscriber. beside her name, in red felt-tip pen, someone had written simply “deceased.” i wondered about this for some time. who was ms. guasco? where had she worked, and when? had she published or otherwise been active professionally? if she was a life member of ala, surely it would be easy to find out more. it turns out that such is not the case, the wonders of the internet notwithstanding. my obvious first stop, google, yielded little other than a brief notice of her death in a pittsburgh-area newspaper and an entry from a digitized september 1967 issue of special libraries that identified her committee assignment in the special libraries assocation and the fact that she was at the time the chief librarian at mcgraw-hill, then located in new york. as a result of checking worldcat, where i found a listing for her master’s thesis, i learned that she graduated from the now-closed school of library service at columbia university in 1953. if she published further, there was no mention of it on google. my subsequent searches under her name in the standard online lis indexes drew blanks. from there, the trail got even colder. mcgraw-hill long ago forsook new york for the wilds of ohio, and it seems that we as a profession have not been very good at retaining for posterity our directories of those in the field. a friend managed to find listings in both the 1982–83 and 1984–85 volumes of who’s who in special libraries, but all these did was confirm what i already knew: ms. guasco was an ala life member, who by then lived in pittsburgh. i’m guessing that she was then retired, since her death notice gave her age as eighty-six years. of her professional career before that, i’m sad that i must say i was able to learn no more. microsoft word december_ital_perrin_final.docx usability  testing  for  greater  impact:     a  primo  case  study     joy  marie  perrin,   melanie  clark,     esther  de-­‐leon,     lynne  edgar     information  technology  and  libraries  |  december  2014         57   abstract   this  case  study  focuses  on  a  usability  test  conducted  by  four  librarians  at  texas  tech  university   (ttu).  eight  students  were  asked  to  complete  a  series  of  tasks  using  onesearch,  the  ttu  libraries’   implementation  of  the  primo  discovery  tool.  based  on  the  test,  the  team  identified  three  major   usability  problems,  as  well  as  potential  solutions.  these  problems  typify  the  difficulties  patrons  face   while  using  library  search  tools,  but  they  have  a  variety  of  simple  solutions.   introduction   the  texas  tech  university  libraries’  usability  taskforce  was  created  to  inform,  facilitate,  and   promote  usability  initiatives  for  services  supporting  teaching,  learning,  and  research.  the  team’s   first  assignment  was  to  study  the  libraries’  new  implementation  of  primo,  a  discovery  tool  by  ex   libris,  which  is  capable  of  simultaneously  searching  all  library  resources.  primo,  branded   onesearch  for  public  use  at  the  ttu  libraries,  was  initially  implemented  with  no  further   customization.  library  administration  charged  the  team  to  evaluate  the  primo  interface  as  set  up,   determine  whether  the  tool  served  patrons  in  an  intuitive  way,  identify  problem  areas,  and  share   possible  improvements  with  the  library  systems  group.  the  issues  the  team  encountered,   problems  found,  and  lessons  learned  along  the  way  are  relevant  across  all  library  usability  efforts   and  may  assist  other  organizations  in  developing  better  searching  tools.     the  purpose  of  this  study  was  to  evaluate  how  well  onesearch  served  library  patrons  and  to   identify  ways  it  could  be  improved  before  it  replaced  the  existing  library  search  tools.  the   information  collected  about  the  website  navigation  and  searching  practices  of  ttu  students  was   also  expected  to  assist  instruction  librarians  in  teaching  students  how  to  use  onesearch.     method   the  usability  study  comprised  two  components  to  evaluate  both  onesearch  use  and  patron   thoughts,  comments,  and  observations.  the  first  component  was  a  series  of  seven     joy  marie  perrin  (joy.m.perrin@ttu.edu),  is  assistant  librarian,  digital  resources  unit,     melanie  clark  (melanie.clark@ttu.edu)  is  associate  librarian,  architecture  library,     esther  de-­‐leon(esther.de-­‐leon@ttu.ed)  is  assistant  librarian  for  electronic  resources,     lynne  edgar  (lynne.edgar@ttu.edu)  is  assistant  librarian,  library  systems  office,  texas  tech   university  library,  lubbock,  texas.     usability  testing  for  greater  impact:  a  primo  case  study  |  perrin,  clark,  de-­‐leon,  and  edgar      58   tasks  that  participants  completed  using  onesearch  while  the  team  observed.  each  participant  was   guided  through  the  process  by  a  facilitator  who  would  prompt  the  participant  when  he  or  she  got   stuck.  the  rest  of  the  team  observed  both  the  participant’s  screen  movements  and  audiovisual   footage  of  the  participant’s  facial  reactions  from  another  room,  with  the  help  of  techsmith’s   morae  usability  software.  while  morae  made  the  observation  process  easier,  the  same  results   could  have  been  achieved  through  simple  screen-­‐capture  software,  a  video  camera,  or  simple  note   taking  by  the  facilitator.  in  addition  to  the  observation,  the  team  used  retrospective  recall,  asking   the  patrons  to  think  through  their  choices  after  the  tasks  were  done  and  explain  their  process.1   the  second  component  to  the  study  was  the  system  usability  scale  (sus),  a  standard  survey  used   to  evaluate  systems  based  on  self-­‐reported  user  experience.2  participants  completed  the  sus   survey  after  finishing  the  tasks.   for  the  first  component,  the  tasks  were  developed  to  cover  seven  types  of  materials  a  patron   might  find  using  the  search  tool:     1. you  are  looking  for  a  work  called  “operations  management”  by  roberta  russell.  find  out  if   the  library  has  this  book  and  if  you  can  check  it  out.  if  the  library  has  it,  where  is  it  located?   2. you  are  not  on  campus,  but  you  want  to  read  a  book  about  human  resources  management.     see  if  there  are  any  books  available  online  and  if  you  find  them,  try  to  read  one  of  them.   3. find  the  database  jstor  and  open  it.   4. you  need  to  find  a  full-­‐text  online  article  about  customer  service  training.  try  to  find  an   article  and  view  it.   5. you  want  to  see  a  picture  of  someone  from  the  1977  volume  of  the  texas  tech  yearbook   (la  ventana).  locate  the  yearbook  and  then  open  the  first  page  of  1977.   6. find  dr.  rebecca  k.  worley’s  ttu  thesis  the  house  of  yes:  a  director’s  approach  and  find   the  abstract  of  the  thesis.   7. you  need  to  find  a  picture  of  frank  lloyd  wright’s  fallingwater.  find  the  picture  and  access   it.     the  order  of  the  tasks  was  important  to  test  the  learnability  of  the  system  and  minimize  user   frustration.  the  first  task  was  a  simple  book  search,  allowing  participants  to  familiarize   themselves  with  the  tool.  the  difficulty  of  the  searches  increased  over  the  next  three  tasks.  the   method  of  “start  easy,  finish  hard”  is  recommended  in  the  cuep  workshop  to  test  memorability   and  learnability  of  the  website.3  however,  the  team  varied  this  model  by  designing  the  last  three   tasks  to  be  similar  to  the  first  two.  these  tasks  each  requested  a  different  material  type,  but  all  the   materials  could  be  found  with  a  simple  search  identical  to  that  of  the  first  task.  this  design  showed   whether  participants  learned  how  to  use  the  system  and  remembered  the  process.  participants   struggling  with  the  last  tasks  would  indicate  a  severe  usability  problem.   the  team  timed  participants’  performances  with  each  task  and  noted  each  error  or  problem   encountered.  each  task  was  labeled  as  either  a  success  or  failure  for  each  participant  depending   on  whether  he  or  she  completed  the  task,  had  to  be  guided  to  complete  it,  or  gave  up.     information  technology  and  libraries  |  december  2014   59   participants   eight  patrons  participated  in  the  study.  from  a  demographic  profile  that  participants  filled  out   prior  to  completing  the  tasks,  the  team  identified  three  expert  users,  three  intermediate  users,  and   two  novices.  student  classification,  how  frequently  the  participant  used  the  library  website,  and   the  ways  the  participant  used  the  library  website  all  factored  into  the  user  status.   results   system  usability  scale  score   the  system  usability  scale  “grades”  a  website  or  system  by  how  usable  patrons  perceive  the   system  to  be,  resulting  in  a  single  number  score.  a  score  above  80.3  is  in  the  top  10  percentile  and   is  considered  to  be  an  a.  a  score  of  68  is  average,  with  anything  under  68  below  average.4   onesearch  received  a  sus  score  of  78.25  from  the  eight  participants  of  the  study.  this  is   comparable  to  a  b+,  indicating  that  overall,  the  implementation  of  onesearch  was  successful,  at   least  in  terms  of  how  students  perceived  it  after  using  it.  to  identify  specific  problems  with  the   interface,  the  team  looked  at  three  factors  of  the  participants’  performances  on  the  tasks.   average  time  spent  on  each  task   figure  1  shows  the  statistics  of  the  seven  tasks.  as  expected  according  to  the  average  completion   time,  participants  spent  more  time  on  the  first  task.  it  may  be  inferred  that  they  were  acquainting   themselves  with  the  system.  the  fourth  task,  which  the  team  expected  to  be  the  most  difficult,   proved  to  have  the  longest  completion  time.  from  the  completion  time  alone,  the  team  was  unable   to  determine  if  task  4  was  problematic  or  not.  while  participants  started  their  search  with  the   onesearch  interface,  they  had  to  wait  for  a  separate  integrated  system,  such  as  a  citation  linker,  to   retrieve  any  found  articles.  this  added  to  the  task  completion  time.     task   average  completion

 primo  case  study  |  perrin,  clark,  de-­‐leon,  and  edgar      60   a  more  telling  observation  was  that  the  time  on  tasks,  excluding  task  4,  diminished  between  task  1   and  task  7,  suggesting  that  participants  had  no  trouble  learning  and  remembering  how  to  use  the   system.   error  rate  for  each  task   the  error  rate  proved  to  be  the  most  accurate  indicator  of  usability  problems  with  each  task.  each   time  a  participant  chose  a  wrong  path,  faced  an  impasse,  or  had  to  be  guided  by  the  facilitator,  the   event  was  labeled  as  an  error.  in  the  ideal  scenario,  the  participants  would  make  no  errors;   therefore,  the  more  errors  observed,  the  greater  indication  of  a  usability  problem.   as  seen  in  table  1,  although  the  first  task  took  an  average  of  1.74  minutes,  the  eight  participants   tended  to  only  make  a  mistake  once  while  trying  to  find  a  book.  tasks  2,  5,  6,  and  7  had  an  average   error  rate  below  1.  because  the  error  rate  seems  to  decline  from  task  1  to  task  7  (excluding  tasks  3   and  4),  the  team  inferred  that  users  were  able  to  learn  how  to  use  the  system  quite  easily.   tasks  3  and  4  seemed  to  cause  problems.  both  of  these  tasks  had  an  average  error  rate  above  3.   this  indicated  to  the  team  that,  since  the  sus  score  for  the  entire  system  was  good,  they  needed  to   identify  why  the  database  search  and  article  search  were  problematic.   success  rate  for  each  task   table  1  also  shows  the  three  ways  that  tasks  were  tagged  during  the  study.  the  participants   completed  the  task  with  ease,  completed  the  task  with  difficulty,  or  failed  to  complete  the  task.  as   the  team  expected,  the  first  task  was  divided  between  those  who  completed  it  with  ease  and  those   who  completed  it  with  difficulty.  this  was  expected  when  the  participants  were  learning  the   system.  task  2  shows  a  marked  improvement:  82.5  percent  of  the  participants  found  an  e-­‐book   with  ease.  tasks  3  and  4  however,  show  up  again  as  problematic.  one  of  the  participants  failed  to   complete  task  4.  after  tasks  3  and  4,  the  participants  successfully

 error  rates  on  the  first  two  tasks,  but  the  novice  error  rates   increased  dramatically  on  the  most  difficult  tasks  (3  and  4),  surpassing  those  of  the  intermediate   and  expert  users.  the  tendency  of  more  experienced  users  to  perform  complex  searches  did  not   negatively  affect  the  their  success  in  completing  each  task.       figure  1.  onesearch  home  page     usability  testing  for  greater  impact:  a  primo  case  study  |  perrin,  clark,  de-­‐leon,  and  edgar      62   problems  identified   figure  1  is  a  screen  shot  of  the  onesearch  interface  used  for  the  study.  as  shown,  there  are  three   tabs  for  different  searches.  the  first  tab,  “texas  tech  libraries,”  searches  the  print  collections,   institutional  repository,  digital  collections,  special  collections,  and  e-­‐books.  the  second  tab,   “articles  by  subject,”  is  a  federated  database  search  that  can  be  narrowed  by  subject.  to  find  a   specific  database,  users  had  to  click  on  the  a–z  link  either  in  the  upper  right  corner  or  at  the  lower   left  under  the  image.   the  test  indicated  that  users  faced  the  most  trouble  when  searching  for  articles  and  opening   specific  databases.  the  team  identified  three  problems  based  on  the  difficulties  the  participants   experienced.  all  of  these  problems  were  related  to  visual  design  and  clarity  rather  than  the  basic   functionality  of  onesearch.  identifying  problems,  however,  does  not  address  how  to  best  resolve   those  problems.  observing  participants  using  the  interface,  as  well  as  researching  current  web   standards,  may  lead  to  educated  guesses  as  to  possible  solutions.  knowing  the  limitations  of  how   the  onesearch  interface  design  could  be  changed,  the  team  decided  to  offer  as  many  possible   solutions  as  could  be  identified.  this  was  to  highlight  that  there  was  no  single  way  to  fix  the   problems,  but  many  different  ways  the  problem  could  be  solved.  the  team  put  the  options  in  order   of  their  expected  effectiveness  on  the  basis  of  what  was  observed  during  the  test.   problem  1:  individual  databases  are  difficult  to  find   while  analyzing  the  task  completion  statistics  and  video  footage,  it  became  clear  that  the  way  to   access  the  databases  was  not  visible  to  users.  as  shown  in  figure  1,  the  “databases  a–z”  link  was  at   the  very  bottom  of  the  page  in  a  location  not  immediately  noticeable.  in  addition,  the  formatting   on  the  link  did  not  look  like  an  obvious  link.  even  if  users  saw  it,  they  might  not  realize  it  was   something  they  could  click  on.   solution  1:  if  possible,  make  “find  databases”  a  search  scope  in  the  dropdown  menu.  the   participants  were  more  willing  to  go  to  the  menu  than  to  look  around  the  page.  this  meant  that   the  best  place  for  users  to  be  able  to  search  databases  was  by  selecting  them  on  the  dropdown   menu.  this  solution  was  not  possible  in  onesearch,  however.   solution  2:  make  “find  databases”  a  fourth  tab.  participants  were  also  more  likely  to  look  through   the  tabs  than  they  were  to  see  the  database  link  at  the  bottom  of  the  page.     solution  3:  move  “find  databases”  or  “databases  a–z”  to  a  different  part  of  the  page.  figure  2  is  a   mock-­‐up  of  different  ways  this  option  could  be  implemented.  this  was  to  highlight  that  as  long  as   the  link  was  put  higher  on  the  page,  in  a  more  visible  place,  users  would  be  more  likely  to  find  it.   solution  4:  make  “databases  a–z”  bigger  or  more  eye-­‐catching  by  changing  the  color.  this  would   increase  the  likelihood  of  it  being  seen.       information  technology  and  libraries  |  december  2014   63     figure  2.  suggested  locations  for  databases  a–z   problem  2:  dropdown  limiters  are  misleading   in  figure  1,  three  search  limiters  can  be  seen  below  the  search  box.  the  ones  shown  in  figure  1  are   “all  items,”  “that  contain  my  query  words,”  and  “anywhere  in  the  record.”  the  first  box  provides  a   way  to  limit  the  results  by  type  such  as  “books”  or  “ejournals”.  the  second  box  offers  a  choice   between  a  general  search  for  query  words,  specifying  if  the  search  is  an  exact  phrase  search  or  if  a   field  starts  with  the  query  words.  the  last  box  offers  a  way  to  specify  which  field  the  query  is   searching.  some  of  the  participants  ran  unsuccessful  searches  during  the  test,  and  then   erroneously  tried  to  get  results  by  “limiting”  the  items  in  their  already  faulty  search.  for  example,   a  few  students  went  to  the  “articles  by  subject”  tab  and  searched  for  an  image  (task  7).  when  no   images  came  up,  they  went  to  the  limiters  and  chose  the  format  “images.”  this  resulted  in  zero   results  returned  because  there  were  no  images  in  the  “articles  by  subject”  tab.  again,  the  team   gave  three  different  options  in  order  of  their  perceived  effectiveness.     solution  1:  on  the  “texas  tech  libraries”  tab,  remove  “articles”  from  the  dropdown  limiter.  the   reason  behind  this  was  that  there  were  no  articles  in  the  basic  search,  so  it  should  not  be  an  option.   solution  2:  on  the  “texas  tech  libraries”  tab,  remove  “databases”  from  the  dropdown  limiter   (unless  “find  databases”  can  work  as  a  search  scope).   solution  3:  on  the  “articles  by  subject”  tab,  remove  “images”  and  “journals”  from  the  dropdown   limiter.     usability  testing  for  greater  impact:  a  primo  case  study  |  perrin,  clark,  de-­‐leon,  and  edgar      64   however,  most  participants  did  expect  all  of  the  content  to  be  in  the  main  dropdown  menu  and  did   not  tend  to  use  the  tabs  or  limiters.  the  team  offered  a  mock-­‐up  of  the  best  possible  scenario  in   which  the  only  options  to  search  were  in  the  main  dropdown  (figure  3).  this  would  have  been  the   most  intuitive  way  for  patrons  to  search,  but  it  was  also  the  most  technically  complex  to   implement.     figure  3.  dropdown  menu  suggestion   problem  3:  “articles  by  subject”  tab  is  not  visible  to  users   the  “articles  by  subject”  tab,  which  allows  users  to  choose  a  federated  database  search  by  subject,   was  not  visible  to  participants.  the  text  was  smaller  than  other  surrounding  text  and  not   immediately  recognizable  as  a  tab.  one  of  the  reasons  that  the  tabs  were  removed  from  figure  3  is   that  they  were  not  easy  for  users  to  see.  the  team  recommended  three  options.     solution  1:  make  the  tabs  more  visually  identifiable  by  designing  them  more  like  traditional   website  tabs.   solution  2:  enlarge  the  tab  text  so  that  the  tabs  are  more  visible.  figure  4  shows  a  mock-­‐up  with   enlarged,  more  noticeable  text.   solution  3:  add  an  “articles  by  subject”  description  to  the  “what  am  i  searching?”  text.  the  team   noticed  that  the  explanatory  text  on  the  right  side  of  the  page  did  not  include  a  description  of  the   “articles  by  subject”  tab.     information  technology  and  libraries  |  december  2014   65     figure  4.  enlarged  tabs   other  minor  problems   in  addition  to  the  three  major  problems,  the  team  noted  smaller  issues.  one  of  the  problems  was   that  some  of  the  titles  of  the  dropdown  search  scopes  were  not  in  terminology  that  the  students   understood.  for  example,  one  of  the  scopes  is  “thinktech,”  the  name  of  texas  tech’s  institutional   repository.  since  this  name  doesn’t  indicate  what  the  scope  actually  searches—mainly  theses  and   dissertations—users  didn’t  know  what  was  in  “thinktech”  unless  they  read  the  explanatory  text   on  the  right.  the  team  recommended  changing  the  scope  name  to  something  more  descriptive,   such  as  “theses,  dissertations,  faculty  research.”   another  small  usability  problem  was  how  difficult  it  was  to  see  the  indication  of  an  incorrect   search.  the  “did  you  mean?”  spelling  suggestion  on  the  search  result  page  was  very  small,  smaller   than  the  notification  that  there  were  no  results.  participants  who  made  simple  spelling  errors   didn’t  realize  they  had  failed  because  of  this  simple  error  and  assumed  there  were  no  results.   discussion   the  team  submitted  these  findings  to  the  library  systems  group  in  two  different  ways:  a  written   report  and  a  presentation  including  the  above  mock-­‐ups,  charts,  and  video  footage  from  the   usability  study.    the  video  clips  allowed  the  team  to  both  illustrate  the  problems  and  show  the   systems  group  the  sources  of  those  problems.  the  presentation  with  more  multimedia  content   made  a  much  greater  impact  than  the  written  report  and  resulted  in  the  systems  group  better   understanding  the  problems  and  how  to  fix  them.  visual  aids  are  an  effective  way  to  report  results   because  of  how  crucial  visibility  is  in  usability.  one  example  of  how  the  presentation  was  more     usability  testing  for  greater  impact:  a  primo  case  study  |  perrin,  clark,  de-­‐leon,  and  edgar      66   effective  is  that  the  team  played  a  game  with  the  systems  group  by  showing  figure  2  without  the   “databases  a–z”  links  circled.  the  systems  group  was  asked  to  raise  their  hands  when  they  first   saw  the  link.  after  everyone  raised  their  hands,  the  next  slide  showed  all  the  locations  that  the   “databases  a–z”  link  could  be  found.  most  of  the  group  had  not  realized  there  was  more  than  one   link,  illustrating  that  some  positions  are  more  noticeable  than  others  and  that  users  tend  not  to   linger  on  a  page.  this  was  more  effective  than  a  dry  report  stating  this  fact.   implementing  usability  findings  is  often  more  difficult  than  identifying  them,  particularly  when   usability  is  conducted  on  a  “finished”  system.  not  all  the  problems  the  team  identified  were  able  to   be  addressed,  but  some  problems  were  fixed  quickly  and  easily,  such  as  including  the  link  “find   databases”  at  the  top  of  the  page  (see  problem  1,  solution  3  above).  what  the  usability  study  did   was  allow  the  systems  group  to  understand  how  patrons  view  their  tool  and  how  they  are  likely   to  work  with  it.       conclusion   these  small  changes  made  the  system  more  usable  for  patrons,  which  is  what  usability  testing  is   all  about.  it  is  less  about  making  a  system  conform  to  a  single  way  of  doing  things  than  finding   small  ways  that  the  system  can  be  made  easier  to  use.  changing  the  name  of  the  search  scopes  or   changing  the  position  of  a  link  is  a  relatively  small  investment  of  time  and  resources  that  yields   great  benefits  for  patrons  in  making  the  system  easier  to  use.     one  of  the  most  interesting  observations  from  this  study  was  that  most  of  the  users  wanted  all   their  search  options  in  one  place.  they  preferred  one  dropdown  menu  to  handle  all  their  needs.     for  future  development  on  these  kinds  of  systems,  this  kind  of  preference  should  be  kept  in  mind.     the  majority  of  patrons  might  be  happier  with  a  tool  with  less  capability  and  simpler  options   rather  than  a  complex  tool  with  many  different  ways  to  approach  their  search.   references     1.  brian  still  and  m.  [qy:  first

information technology and libraries |december 2013 8 abstract as mobile technologies continue to evolve, libraries seek sustainable ways to keep up with these changes and to best serve our users. previous library mobile usability research has examined tasks users predict they might be likely to perform, but little is known about what users actually do on a mobile-optimized library site. this research used a combination of survey method and web analytics to examine what tasks users actually carry out on a library mobile site. the results indicate that users perform an array of passive and active tasks and do not want content choices to be limited on mobile devices. responsive design is described as a long-term solution for addressing both designers’ and users’ needs. introduction technology is in a constant state of flux. as librarians well know, emerging technology can quickly become outdated in a few short years. in 2010 blackberry phones were at their peak, but now their mobile devices account for a little more than 5 percent of the market share and the android dominates the top spot, with approximately 52 percent of the market share.1 as smartphone use and design has continued to proliferate and advance, users have become accustomed to quicker load times for webpages and are now well-acquainted with how to navigate the web from their phones. as the mobile phone market changes and evolves, usability experts continuously update, test, and revise standards for the mobile web. at oregon state university (osu) we recently set out to improve our mobile site. this required updating our knowledge about patron use of library mobile sites, both through reviewing the literature and by conducting our own primary research. what we found surprised us and challenged us to reconsider what we had previously assumed about patrons’ mobile habits. in this article we will describe past research on library mobile website usability, our own research on how our mobile library site is used, and why we ended up deciding to use responsive design as the guiding principle for our redesign. hannah gascho rempel (hannah.rempel@oregonstate.edu), is science librarian and graduate student services coordinator, oregon state university, corvallis, oregon. laurie bridges (laurie.bridges@oregonstate.edu), a lita member, is instruction and emerging services librarian, oregon state university, corvallis, oregon. mailto:hannah.rempel@oregonstate.edu mailto:laurie.bridges@oregonstate.edu that was then, this is now: replacing the mobile-optimized site with responsive design | rempel and bridges 9 background: that was then in early 2010 we co-authored an article with our then-programmer about the mobile landscape in libraries. we were among the first to propose that libraries should develop separate websites and catalog interfaces optimized for mobile devices.2 based on the widespread implementation of mobile-optimized library websites since then, it appears this proposal was both relevant and timely. our 2010 recommendations were based on usability studies, library reports, and technology trends from 2007 through 2009. research and literature at the time pointed to the need for considering the mobile context, for example, the “attention span” of mobile users as they search for information on the go.3 we noted the advice of jakob nielsen, who indicated that “if mobile use is important to your internet strategy, it’s smart to build a dedicated mobile site.” although that particular webpage is no longer available, the essence of nielsen’s thinking can be found in a mobile usability update posted on september 26, 2011, which states, “a dedicated mobile site is a must,” in the introductory paragraph.4 the iphone was released in the united states in late 2007, and in 2008 the proliferation of dedicated mobile sites began. in december 2008, our mobile team focused on developing a site for the two most popular device types at the time, “smartphones” and “feature phones.” the differences between the two types of phones were numerous and there were drawbacks to the feature phones. however, we felt it was important to have a site that rendered well on feature phones because at that time feature phones dominated the market with only 28 percent of mobile phone users in the united states owning a smartphone.5 our initial site design in 2008 and 2009 focused on our primary users, members of the university community. the first phase of our mobile website, released in march 2009, included static pages like library hours, contact information, frequently asked questions, and directions.6 the second phase, released in september 2009, included a mobile catalog interface (designed in-house), a staff directory, and a computer availability map. in february 2010 the site averaged one hundred unique users a day. mobile site analytics showed that the most viewed pages were computer availability, catalog, and hours. background: this is now recent research and case studies show a shift in the mobile context. a comprehensive study by alan aldrich in 2010 examined the mobile websites of large research universities and their libraries in the united states and canada. aldrich notes, “users seem to want access to information just as if they were using a fully web-capable desktop or laptop computer.” aldrich ponders the possibility that patron expectations and desires may be evolving as smartphones begin to dominate the mobile landscape.7 in 2011, jakob nielsen noted that because most people do not use the web on their feature phones and most companies do not support feature phones in their web design process, he would no longer be testing feature phones in his usability studies.8 our experience matches nielsen’s on this information technology and libraries | december 2013 10 point; approximately 10 percent of daily users accessing our library’s mobile site came from feature phones in 2010; in 2012, that number had dwindled to less than 1 percent. in 2012, nielsen began considering the proliferation of mobile devices beyond phones, when he wrote, “high-end sites will need 3 mobile designs to target phones, mid-sized tablets, and big tablets.”9 note the slight change in the phrase “dedicated mobile site” (from the 2009 mobile usability update) to “mobile designs.” nielsen goes on to suggest responsive design, which we will address in more detail later in this article, as a solution to this design problem. as we prepared for another redesign of our mobile site, we knew we needed a current snapshot of users and how they actually use the mobile version of the library’s website before starting our redesign. this may sound like a simple decision; however, it is a step that the library literature has not documented well. researchers have focused on what library users predict they might need rather than analyzing their actual behaviors. mobile site user experiences mobile library website development has been influenced by other, nonlibrary mobile sites that have placed heavy emphasis on developing sites for users who are on the go.10 earlier studies examining general mobile browsing and searching habits found that mobile users’ most popular activities were reading news, weather, or sports articles, looking for information using search engines, and checking email.11 when libraries used these studies to inform mobile site development, the result was a streamlined version of the full library site. it is instructive to consider studies like those done by coursaris and kim, who performed a meta-analysis of more than one hundred mobile usability studies. they demonstrated both the extreme breadth of mobile usability research, which has examined everything from how users perform tasks on their mobile devices while walking on a treadmill to how users navigate mobile maps, to mobile restaurant selection, as well as the niche-specific nature of many of these studies, the results of which may not be transferable to other contexts.12 when looking at mobile usability studies specifically within the higher education sector, a field more closely related to libraries, research focuses primarily on the use of mobile phones for enhancing student learning through specific activities or sites.13 less research examines how mobile portal or university homepages are used. one exception is the iowa course online (icon) mobile device survey, which was administered in 2010 and asked students what aspects of icon (a course management system) they used on their mobile devices.14 students were frequent users of this site; three-quarters of respondents used the site at least 1–3 times per week. the top three selected tasks were grades, “content” (a category including pdfs and microsoft word documents), and schedules. as defined by kaikkonen, users’ top tasks included a mix of “passive” content that require no additional interaction (e.g., grades, weather) and “active” content, which requires further searching, reading, or location-specific information from the user (e.g., searching in web browsers, mapping, or looking through pdfs). 15 the combination of passive and active content more closely matches the types of tasks potentially required by mobile library website users. that was then, this is now: replacing the mobile-optimized site with responsive design | rempel and bridges 11 research on library mobile site use or usability primarily has focused on users’ speculations about what they might like from a mobile library site before the site was constructed, or on a handful of users’ experiences navigating an existing site while accomplishing researcher-assigned tasks.16 no known research exists that demonstrates what tasks users actually perform on an existing mobile library website in real-time. for example, focus groups conducted in 2009 at kent state university library before the creation of their mobile site led to the conclusion that “students want the site for ‘quick research’ not to ‘sit down and write a term paper on my phone,’” and that students did not want as many research choices, such as all of the databases the library subscribes to, made available on their mobile device (or perhaps even on the full website).17 a survey at the open university in the united kingdom given prior to deployment of the mobile site extrapolated that students would want to access library hours, a map of the library, contact information, the library catalog and their borrowing record from their mobile device.18 in addition, a survey of the student body at utah state university in 2011 intended to help inform their mobile site design found that students might want to access the mobile catalog, retrieve articles and reserve study rooms.19 these results helped determine the future development of these academic library mobile websites and were interpreted to demonstrate that particular tasks might be better suited for the mobile environment. however, they also demonstrate that student users might want to engage in a variety of both active and passive tasks, such as searching the library catalog and checking the library’s hours. as part of a growing recognition that it is time to reevaluate mobile library sites, bohyun kim, reviewed eight library mobile sites, and presented her analysis at the american library association annual conference in 2012.20 kim compared screenshots of 2010 and 2012 homepages and found a greater emphasis on search in the 2012 versions. kim also highlighted constraints and assumptions that are no longer true in the mobile environment, such as mobile devices’ slow networks, a focus on information on the go, and mobile sites with fewer features and content. kim’s analysis signals a shift in how libraries, as well as the broader mobile environment, are envisioning the content they provide on their mobile sites. because websites designed for the mobile context are still relatively new, an important part of this shift in the design of library’s mobile sites should include an investigation into what types of tasks users are actually performing on these sites. using web analytics software, we are able to learn which mobile webpages are the most visited on osu’s mobile site, and we know the path users took from the first hit to when they exited the site. however, what we do not know is what the user’s intention is in visiting the site, what types of searches they enter, or if these users are able to accomplish their search goals. the objectives of this study were to gather a list of tasks users attempt to accomplish when visiting the library mobile site and to understand the difficulties users encounter when they try to access information on the osu’s mobile site. a more in-depth understanding of how our mobile website is used will help us to provide an improved interface, especially as we work on a site redesign. information technology and libraries | december 2013 12 methods this study used an online survey instrument to gain a better understanding of what tasks mobile site visitors are trying to perform when they visit our library’s mobile site, to discover whether they were able to accomplish their task, and any other general impressions, suggestions, or feedback these users had about our mobile library site. this survey (approved by osu’s institutional review board) was available on the qualtrics survey platform for twelve-weeks from november 2012 to january 2013. the survey was accessible via a link on the mobile version of our library’s homepage, meaning that only users who used the mobile-optimized version of our website had access to the survey. the survey was open to anyone who used the library’s mobile website, not just osu affiliates. the survey was completed by 115 participants. a $2 gift certificate to a coffee shop was distributed to participants upon completion of the survey. because mobile site use can cover a complex range of scenarios, and because we were more interested in learning about what this range of scenarios was for our mobile site, we did not use a closed-task scenario with preset tasks. we asked real users who were currently browsing the mobile site to choose from a list of tasks that best described what they were searching for on the library's mobile site (there were also open-ended questions and options). if they were looking for a book or planned to conduct research on a topic, we used display logic in our survey to further probe their answer and ask about the parameters of their search. if they indicated they had previously used the mobile site to search for books or other research materials, we used the same method used with the book search to ask if they were able to find these materials. if they were looking for articles, we then asked if they read the articles on their mobile device. in addition, we asked if there was anything they wished they could do on the site and for any other general feedback on the mobile site. finally, we collected some demographic information about the participants: their osu affiliation and the frequency with which they use the library’s mobile site. the survey data was analyzed using qualtrics’ cross-tab functionality and microsoft excel to observe trends and potential differences by user groups. open-ended responses were examined for common themes. to help provide some counterbalance to our survey data, a combination of urchin and google analytics statistics were analyzed for two of the months the survey was available. urchin statistics were gathered for the mobile version of the website, and google analytics statistics of our drupal-based pages were gathered for mobile users of the full version of the library’s website. we tabulated average daily visitors, specific page views, and the type of browser used with these analytical tools. findings online survey—closed-ended questions an advantage of administering a survey versus simply using web analytics to assess a mobile site is that more granular information, such as demographics, can be gathered. of the 115 online survey respondents, 74 identified themselves as undergraduate students, 19 were graduate that was then, this is now: replacing the mobile-optimized site with responsive design | rempel and bridges 13 students, 8 were faculty members, 3 were community members, 2 were alumni, 2 were staff members, and 1 chose the “other” field and self-identified as a parent (see figure 1). not all respondents answered every question. because undergraduates make up the overwhelming majority of the campus body, it makes sense that 64 percent of respondents identified themselves as undergraduates. however, the demographic responses also illustrate that multiple user groups access the library’s mobile site. figure 1. demographic distribution of survey respondents (n = 109). the survey participants were asked how often they had previously used the library’s mobile site. sixty-nine respondents (60 percent) were accessing the site for the first time. no respondents used the mobile site daily, 1 respondent visited 2–3 times per week, 5 respondents (4 percent) visited once a week, 11 respondents (9.5 percent) visited 2–3 times per month, 7 respondents (6 percent) visited once a month, and 16 (14 percent) visited less than once a month (see figure 2). the majority of respondents had not previously used the library’s mobile site. one possible reason for this is that the data was collected primarily during fall term, a time when there are many new students on campus. an alternative explanation is that people who use the mobile site often are highly task-oriented and did not want to be distracted by taking a survey. the fact that the majority of respondents had not previously used the library’s mobile site affected responses to later questions in the survey, which asked participants to remember previous experiences and satisfaction with the site. 1 2 2 3 8 19 74 0 10 20 30 40 50 60 70 80 other staff member alumni community member (non-student) faculty member

109). one of our main research goals was to determine our users’ intention for visiting the library’s mobile site. respondents could choose as many items as were applicable from a list of reasons for visiting the library’s mobile site; as a result, the data is presented as the percent of total responses. respondents could also choose “something else” and enter additional reasons for visiting the mobile site. these “other” reasons were grouped and the groupings are reported in the list of reasons for visiting the site. the top reason respondents visited the site was to view the library’s hours (47 percent). the next two most frequent reasons for visiting the site were research related, with 25 percent intending to look for a book and 21 percent intending to do research on a topic. the fourth and fifth most common choices were associated with using the library building, with 13 percent looking for study room reservations and 10 percent looking for the availability of computers in the library. because the library’s current mobile site has been optimized for tasks perceived to be most important for mobile users, and because some of the features available via the full-site version of our ils (integrated library system) are not available via the library’s mobile site, not all of the tasks respondents wanted to accomplish on the mobile site were actually available on the mobile site. these items include study room reservations (13 percent of responses); “my account” features, such as the ability to check due dates, make renewals, and place holds (6 percent of responses); and interlibrary loan (1 percent of responses). finally, some features that had been considered ideal for the mobile context because of their location-sensitive, time-saving, or hedonic functionality—such as looking for directions (1 percent of responses), finding a quick way to contact a librarian with a question (2 percent of responses), and viewing 0 1 5 11 7 16 69 0 10 20 30 40

determine if different user groups approach the library’s mobile site differently, we compared the reasons for visiting the mobile site across user groups. when looking at the top five reasons respondents visited the mobile site, only a few differences appeared based on user group (because of the small sample size, a statistical analysis determining significance cannot be done, but results may indicate avenues for future research). graduate students were somewhat more likely to visit the library’s mobile site to look for research on a topic, as well as to look for study room reservations. however, undergraduate students were more likely than graduate students to be interested in the availability of computers in the library (see table 1). 1% 1% 1% 1% 1% 2% 2% 3% 4% 6% 10%

tasks. (respondents could choose more than one response.) because the online survey was available over a twelve-week period, which included portions of fall term, winter break, and winter term, we could look at a breakdown of use by time of term. specifically, we wanted to see if there was a difference in use during the middle of the term versus finals week and intersession. during the latter period, we anticipated users would not be using the library’s mobile site for research purposes; however, when comparing these two different usage periods for the top five reasons respondents visited the site, we found respondents’ tasks tended to be quite similar regardless of whether or not the term was in session. the only two differences were (1) during intersession respondents tended to be more likely to search for a book using the mobile site and (2) during the term, more respondents were looking for a way to make study room reservations. while the high number of respondents looking for library hours dominates these results, it does appear that respondents were still using the mobile site to conduct researchrelated tasks even during intersession (see figure 4). that was then, this is now:

visiting the library’s mobile site were research related: looking for a book and doing research on a topic. survey participants indicating they had come to the site looking for a book were prompted to enter the search they intended to use. of the twenty-eight respondents who indicated they were looking for a book, twenty-five provided the search words they planned to use (see table 2). respondents reported a wide range of search types, from known-item titles or authors such as moby dick or ian fleming, to broad topic areas such as women studies, to focused keywords like “high performance computing.” all of these searches fit into the active task category of mobile use. 7% 13% 15% 15% 33% 6% 5% 14% 22% 34% 0% 5% 10% 15% 20% 25% 30% 35% 40% computer availability study room reservations

respondents’ book searches on their mobile device. if a survey participant indicated they had come to the site to conduct research on a topic, we prompted them to provide more detailed information about their search. of the twenty-three respondents who indicated they were conducting research on a topic, twenty provided the search words they planned to use (see table 3). it is apparent from the responses that at least five respondents misunderstood our question, and instead of entering keywords for a search, they entered the databases or search engines they planned to use to conduct their research, such as 1search (our library’s iteration of serials solutions’ summon), eric, psycinfo, and perhaps google; although, when considering the search term google, it is possible the respondent was going to attempt to conduct research on the google company itself. the remaining search terms reflect indepth concepts that would either retrieve many results (e.g., procurement and contract processes), or that while retrieving fewer results would give the researcher more than just a single simple document to consult (e.g., ethnobotany oregon). as with the book searches, these research topics represent more active tasks that move the mobile user beyond the earlier perceptions of mobile use that predicted tasks centered on quick, entertaining, or location-specific information.21 that

sources. web analytics results in addition to collecting survey responses, we monitored our web analytics during the survey period to see how the site usage matched with our survey respondents’ stated activities. the mobile version of the site averaged 124 daily visitors between november 5, 2012, and january 5, 2013. the top three pages viewed were the computer availability map (37 percent), the mobile homepage (25 percent) and the research page (3 percent). the mobile homepage also displays the library hours. because mobile users do not just use mobile optimized sites, we also looked at mobile use of the drupal-designed pages on the full version of our website. of the top twenty pages viewed, eleven were content pages and nine were navigational pages. based on page views, the top three content pages were study rooms (8 percent), hours (5 percent) and research databases (5 percent). the top three navigational pages based on page views were the homepage (40 percent), which also displays the library hours, the find it page (8 percent), which lists links to content like databases, the catalog, and ejournals, and the in the library page (7 percent), which provides links to information about things a patron might use in the library, such as study rooms or computers. the web analytics do not exactly mirror the tasks reported by the survey respondents and reflect an even greater emphasis on practical tasks like using a computer or a study room in the library. information technology and libraries | december 2013 20 in our research a disconnect appeared between what users actually do on the mobile site, according to urchin and google analytics, and what they would like to do on the site based on information gathered from the participants of our online survey. it became apparent from our survey that our participants were not only attempting simple searches appropriate for a strippeddown mobile-optimized site but were also attempting active tasks, like conducting more complex searches we formerly would have expected them to do only on the full site. we needed a website that no longer restricted the activities our users could do based on our outdated assumptions of their use of our website. responsive design as a solution to our problem of how to provide a consistent, nonrestricted experience to all of our users regardless of how they were accessing our site, we turned to the concept of responsive design. responsive design was conceived as recently as 2010,22 but adoption is growing rapidly because it offers a more scalable solution for designers, allowing them to move away from designing different websites for every platform, and instead designing sites that scale differently in different contexts (for example, an iphone vs. an ipad). responsive design is a more dynamic strategy, requiring as web designer ethan marcotte states, “fluid grids, flexible images, and media queries.”23 however, marcotte goes on to argue that responsive design “requires a different way of thinking. rather than quarantining our content into disparate, device-specific experiences, we can use media queries to progressively enhance our work within different viewing contexts.” the following images illustrate the reflow of a responsive design layout for desktop and tablet views. figure 5. desktop view of responsive osu libraries webpage. that was then, this is now: replacing the mobile-optimized site with responsive design | rempel and bridges 21 figure 6. tablet view of responsive osu libraries webpage. this summer, our web designer redesigned both the full site and mobile site using responsive design. at osu, we have decided that we will no longer have a separate mobile site. instead, drupal responsive design modules and themes allow our site to be viewed optimally, independent of screen size, as “one web.”24 using a responsive design allowed us to choose a one-column layout for our mobile site and a three column layout for our full site. using drupal modules and themes, the three columns from the full site reflow into one column on the mobile device. menu bars collapse, numerous static pictures become one image box with rotating pictures, and paragraphs are simply linkable titles. these design decisions allow users to perform both active and passive tasks depending on their needs, regardless of context. responsive design provides clear advantages for designers, for example, they no longer need to maintain separate versions of low-use pages, such as a directions page. in addition, while responsively designed websites are not automatically accessible, it is simpler for designers to create a single iteration of a site that meets accessibility guidelines, and which can then scale appropriately to other contexts. however, there are also advantages for the user. responsive design ensures that users will encounter a predictable interface and experience across all of the platforms from which they access the library’s website. moreover, in our local context, we have had a policy of not providing links to websites not optimized for mobile devices, such as databases, from our mobile site. as we switched to a responsively designed site, we moved away from this policy, thereby providing more research choices to our mobile users. there are also some drawbacks to using responsive design in our context. some might consider linking out to resources not optimized for mobile devices a drawback rather than an advantage. in addition, our redesign only involved applying responsive principles to our library sites that are developed in drupal. sites such as the study room reservation system, my account, and the information technology and libraries | december 2013 22 library’s catalog draw upon other vendors’ tools, and therefore are not under our design control. however, access to these sites will no longer be circumscribed for mobile users, but may involve less intuitive navigation depending on their device. conclusion our goal in this study was to gain a more in-depth understanding of how our mobile website is used to guide a redesign of our mobile interface. as a result of examining current trends in web design and development, through analysis of the data we collected that demonstrated not only what our users currently do on our mobile site but also what they intend to do and what gaps they perceive in our service, we have chosen to integrate our full and mobile sites into “one web” through the use of responsive design. gathering qualitative information from our mobile site users has provided us with more realistic tasks that we can use in further usability testing. finally, we are again reminded of the continual evolution of our users’ needs and the expanding possibilities that are available as information becomes increasingly mobile. references 1. jeff clabaugh, “blackberry u.s. market share falls to 5.4 percent; google’s android remains on top,”

development of a himalayan studies information system for india: a proposed model anil singh the ever-increasing need for information, with its complexity and escalating costs; the enormous growth in publications, and the emergence of subject specialization have compelled librarians to share resources through information networks and systems. this paper describes the necessity of networking among the himalayan studies and research centers in india, allowing the sharing of information originating from the himalayan studies information system (himis). the paper also discusses in brief the definition of information systems, as well as the objectives and needs of a proposed himis. the recent advancements in the computer, communications, and networking technologies have brought about three paradigm shifts. there is the shift of information resources from print to electronic media, the shift in the role of information providers from passive to proactive, and the shift from manual to automated information delivery. this has presented library and information professionals with a tremendous challenge, that of playing a proactive role not only in their routine activities (acquisition, processing, and dissemination), but also in the actual learning process of their clientele. library and information professionals have to learn to scan, filter, interpret, analyze, repackage, and deliver information from a variety of sources in ways that are meaningful to their users.1 himalaya, the greatest physical feature of the earth, is not only an integral part of history and heritage, but it has also assumed the form of a social, cultural, and geo-political reality that cannot be ignored or underestimated. this mountain range makes an enormous contribution to our contemporary life, even as it influenced our history and mythology. furthermore, this influence promises to extend even to the future.2 the himalayas have always remained a source of fascination and inspiration for people from all walks of life, and have been deemed by the peoples of the subcontinent to be the cradle of human civilization. the variety of cultures, terrains, forest physiographies, flora, and fauna of this region has lured the intelligentsia of the world since time immemorial. in recent years, however, the himalayas have become the focus of attention of scientists and government alike. efforts are underway for a better understanding of its highly complex environmental and ecological systems, and to bring about an all-around development of the region, which has remained backward throughout the centuries.3 there has been a tremendous explosion of data and information in recent years, particularly in the field of himalayan resources, with an increase in the number of research and development institutions at the national and international level. while most of these research institutions and universities possess excellent libraries and information centers, there is at present no information network by which coordination and sharing of resources could be effected for the mutual benefit of each of the existing libraries. because there is little access to the right information at the right time, it has become difficult for one single organization to collect the data and information that are required by policy makers, administrators, and research scientists. the other scientific departments of the government of india have already started planning to begin information networking in their respective areas. some of these projects are completed and others are in the process of implementation.4 during the last decades, india has been active in setting up information systems and networks, and considerable progress has been achieved in this area (figure 1). since most of the information related to the himalayas is scattered in different research-andstudies centers all over india, there is a need to develop a himalayan studies information system (himis). himis will be a computer-communication network for linking various libraries and information centers of research and development (r&d) institutions, universities, and nongovernmental organizations (ngos) working on the himalayas. the system, therefore, has to take into account the specific information requirements of each development sector so far as its relevance to the himalayas is concerned. defining information systems the purpose of an information system is to provide accurate and relevant information to users at the right time and at the appropriate level of detail. this will help ensure that the corporate information resource is utilized fully.5 buckingham defines an information system as a system which assembles, stores, processes, and delivers information relevant to an organization (or to society), in such a way that the information is accessible and useful to those who wish to use it, including managers, staff, clients, and citizens. an anil singh

communications design and development of a himalayan studies information system for india | singh 37 38 information technology and libraries | march 2005 information system is a human activity (social) system which may or may not involve the use of computer system.6 harrod’s librarians’ glossary defines information system as an organized procedure for collecting, processing, storing, and retrieving information to satisfy a variety of needs.7 according to bowman, four different components can be identified: (1) a store of useful information that has been accumulated over a period of time; (2) a series of techniques used for adding material to and retrieving information from the store upon demand; (3) a group of people who operate the system and are responsible for selecting information to be added, answering questions, organizing the store, and for implementing and modifying the techniques for both storage and retrieval; and (4) the user. the ultimate test of any such system is the degree of satisfaction it gives the user who has specific information needs.8 setting up himis the volume of himalayan information plus the number of users and their various requirements have created a situation where it is almost impossible for any single library to provide information services singlehandedly. it is only through a network of all these information centers that some viable control of himalayan information is feasible, not only at a local level, but also at the national and international level, to ensure effective use of information resources to the best advantage at a minimum cost. these days, information is being regarded as a national resource, and this awareness has led to computerbased information services such as indexing and abstracting at the national and international levels in the field of himalayan studies.9 considering the importance of himis, the government of india, through the agency of the national information systems in science and technology (nissat), should aid and support the proposed himis generously. himis is eminently suitable for several spheres of national activities, including planning and research. reliable and timely information for decisionmaking becomes increasingly important for india, where a concept of social welfare has developed over the past three decades. many organizations have successfully developed their own information systems to plan, monitor, or control their research activities, and these have yielded increased research proficiency. the government should surely benefit from these methods. apart from suggesting suitable solutions to the problems of planning, monitoring, allocation, control, and coordination of the departmental programs, one has to consider the special distribution of these programs.10 the need to set up himis has, therefore, to be considered in the context of the rapid development of himalayan information as well as the increasing awareness of its relevance to societal development.11 objectives of himis himis will be fully computerized so that an efficient system of storage and retrieval could be organized through networks linking all the himalayanstudies centers with each other. the main objectives of the proposed himis are listed in appendix a. users of the proposed system the proposed information system is planned to meet the needs of the specialists who are directly or indirectly concerned with himalayan studies and research as a subject or as an activity. the following are the categories of those to whom the information would be supplied in a meaningful form within a reasonable time through himis. 1. planners, policy makers, decision makers, administrators with respect to himalayan development at government and nongovernment levels; 2. major institutions devoted to himalayan study and research as a discipline; 3. international organizations such as the united nations educational, scientific, and cultural organization

information material on himalayas; and (6) himalayan information gateway. figure 2 depicts the proposed components. national resource center on himalayan studies as a part of the information system, a national-level resource center for himalayan studies is also proposed on the pattern of other information centers in india, such as the national information center for management information (nicman), ahmedabad, and the national information center for food science and technology (nicfos), mysore, to name but two. these information centers have been established with the financial help of nissat, and at present are working as sectoral information centers of nissat. figure 3 describes various functions and activities of the proposed center. the planned objectives of the resource center are: � to create a user-need-based information-technology (it) resource center; � to develop a strong collection of different types of information sources; � to develop a user-friendly information-retrieval mechanism, such as an online facility for having access to international databases; � to create an it-based infrastructure; � to develop a liaison with all himalayan studies and research centers of india and other international centers for better information service through resource sharing and networking; and � to provide bibliographies on selected topics on demand or even in advance of demand. himalayan-studies libraries consortium the concept of library consortia has been floating around for quite some time in india. though it is the need of the hour, indian libraries have yet to move in a definite direction in this regard. strong resource-sharing activity among libraries, a prerequisite for the right attitude towards consortia activities, has not been as present in india as could be desired. sudden influx of electronic information is forcing library consortia to materialize.13 traditionally, the primary purpose of establishing a library consortium is to share physical resources amongst members. access to resources is now considered more important than collection building, especially if the access is perpetual in nature. a library consortium helps libraries to get the benefit of wider access to electronic resources at an affordable cost and at the best terms of license. a consortium with the collective strength of resources of the various institutions available to it is in a better position to address and resolve the problems of managing, organizing, and archiving electronic resources.14 the indian national digital library in science and technology (indest) consortium, which is set up by india’s ministry of human resource and development, and ugc-infonet, which is set up by the university grant commission of india are the best example of library consortia in india. therefore, it is also proposed that a consortium of himalayan institute’s libraries may be formed to share the electronic resources of other libraries. computerization of himalayan-studies institute’s libraries observance of an adherence to standard techniques, procedures, and methods is an essential prerequisite for the effective functioning of a network. participating libraries will have to follow certain procedures and practices, without which the resources held by them cannot be effectively and meaningfully shared. in the context of library computerization, standardization is very necessary in such areas as classification, subject heading, and cataloging of various types of library materials; bibliographic description; and standard interchange of bibliographic data.15 the himalayan institutes have started the computerization of their libraries, beginning with creation of computerized databases of books, journals, reports, conference proceedings, annual reports, and monographs. but not all the housekeeping activities have been computerized. it is, therefore, suggested that every library should begin the computerization of each and every one of their activities. in india, libraries are generally using dewey decimal classification (ddc) for classification, anglo-american cataloguing rules (aacr) for cataloging rules, and library of congress (lc) for subject headings. machine-readable cataloging (marc) fomat is being used in the majority of libraries for creation of the database. design and development of a himalayan studies information system for india | singh 39 40 information technology and libraries | march 2005 himalayan institute’s network it is also proposed that there is a need for networking among the himalayan institute’s libraries and information centers in the country for optimum resource sharing. resource sharing and networking in libraries are powerful tools both for increasing productivity and enhancing services to meet the changing needs of library users. the proposed network ensures effective bibliographic control, document delivery, cooperative acquisition of serials and other literature in the field, and dissemination of relevant information. all the libraries and information centers of himalayan-studies centers of india (see appendix b) will be linked to the national resource center on himalayan stud-ies. these libraries have been identified as regional centers of the proposed himis. a network, in the first instance, envisaged a physical structure of links among the libraries and information centers established by means of computer and telecommunication links. resource sharing is based on the concept that the collective strength and effectiveness of a group of libraries is greater than that of the sum of its individual members. digitization of himalayaninformation sources research publications are vital for any professional discipline, and it is crucial to preserve and provide access to them. due to the amount of important information published in journals, conference proceedings, and reports, these efforts must be on a par with similar initiatives in other countries. permanent preservation and enhanced access must be ensured vigorously now by the applications of new technology for digitizing and electronic access to valuable contents. digitization provides unhindered access to information via computer and communication networks, justifying the need for using it for studying himalayan literature. at present, very few copies of conference volumes, journals, and reports are published, and these are exclusively distributed to subscribers. the institutions involved rarely encourage readers to subscribe personally to such literature, thus placing it out of the reach of a large number of readers. the paper used for publishing these types of sources is of inferior quality, significantly reducing shelf life. in addition to providing increased and easy access to these publications, the most visible benefit of digitization is the fact that it preserves them.16 some of the purposes figure 2. components of himis figure 3. national resources center on himalayan studies in india of digitization, identified by different ongoing projects, are to: � collect, store, and organize information and knowledge in digital form; � promote economic and efficient delivery of information; � leverage considerable investments in computing and communication infrastructures; � strengthen communication and collaboration between research, government, and educational communities; and � contribute for lifelong learning opportunities. keeping all of these points in mind, the digitization of himalayan literature—particularly back volumes of journals, conference proceedings, annual reports, monographs, reports, and research papers published by himalayan scientists in various journals, available in himalayan studies centers of india—is very necessary. and it is one of the important and necessary aspects of the proposed himis. himalayan-studies information and subject gateway one of the major problems in accessing information from the internet is that it is very difficult and time consuming to get reliable and relevant information in the shortest possible time. the effective and efficient way to provide easy access to quality information on the internet is developing subject gateways in specific areas. “subject gateways are online services and sites that provide searchable and browseable catalogues of internetbased resources. subject gateways will typically focus on a related set of academic subject areas.”17 to meet the information requirements of the scientific and academic communities in the digital era, various departments in india have developed or are still in the process of developing subject gateways in their respective areas.18 in recent years, there has been a tremendous explosion of data and information on the internet, particularly in the field of himalayan resources. as a result, it has become difficult for an individual—and also for an organization— to collect data and information. thus, access to the right information at the right time has become very difficult.19 since most of the information related to the himalayas is scattered on the web, it is necessary to develop a himalayan-information subject gateway. this gateway will provide links to various libraries and information centers of r&d institutions, universities, and ngos working in the himalayan region. this gateway will be developed on the pattern of the sayama prasad mookerjee information gateway of social science (spmigss) developed by the indian council of social science research (icssr).20 the system, therefore, has to take into account the specific information requirements of each development sector insofar as its relevance to the himalayas is concerned. institutions engaged in himalayan studies and research to reduce the quantum of information illiteracy, it is essential that information is readily available to an individual about the agencies that generate and publish himalayan information—a huge task. the main hurdle has been the lack of appreciation of the role and importance of this type of institutional activity on a continuing basis. bearing in mind the concern for setting up himis, the first step is to identify the agencies and institutions that generate himalayan information. the information generated by these institutions may be contained in the form of files, computerized databases, reports, institutional publications, dissertations and theses, articles in journals, and conference and seminar papers. the information also is accumulated through state-of-the-art reports, serials, and yearbooks.21 india adinet (www.alibnet.org/) agris (www.fao.org/agris/) calibnet (www.calibnet.org.in/) csir (www.csir.res.in) delnet (www.delnet.nic.in/)

setup for himalayan research. figure 5 lists agencies currently involved in diverse fields of r&d on the himalayas. appendix b lists some of the institutions that are engaged in himalayan studies and research. 22 conclusion all himalayan studies and research centers have to assume the major responsibility for developing himis. the government of india needs to be convinced of the usefulness and utility of such a system. it is necessary to emphasize that in the absence of such an information system, a large amount of research talent and resources will be wasted in duplicated efforts. it is hoped that the himalayan institutions and scientists engaged in himalayan studies and research will be able to impress upon the government of india the need for an early formulation and implementation of himis.23 this information system will also supplement the resources and services of the participating libraries as “libraries acting together can more effectively satisfy user needs and thus meet the objectives at reduced costs.” the success of the venture shall depend upon financial support, guidance, and encouragement received from government of india.24 references 1. r. l. raina, and i. v.

and (h) to promote the design, development, production and distribution of accessible information and communications technologies and systems at an early stage, so that these technologies and systems become accessible at minimum cost. in addition, the convention seeks to guarantee equal access to information by doing the following: (c) urging private entities that provide services to the general public, including through the internet, to provide information and services in accessible and usable formats for persons with disabilities; and (d) encouraging the mass media, including providers of information through the internet, to make their services accessible to persons with disabilities.2 because the internet and its design standards are evolving at a dizzying rate, it is difficult to create websites that are both cutting-edge and standards-compliant. this paper evaluates the challenge of web design as it relates to individuals with disabilities, exploring current standards, and offering recommendations for accessible development. examining the provision of it for this demographic is vital because according to the u.s. census bureau, the u.s. public includes about 51.2 million noninstitutionalized people living with disabilities, 32.5 million of which are severely disabled. this means that nearly one-fifth of the u.s. public faces some physical, mental, sensory, or other functional impairment (18 percent in 2002).3 because a library’s mandate is to make its resources accessible to everyone, it is important to attend to the special challenges faced by patrons with disabilities and to offer appropriate services with those special needs in mind. n current u.s. regulations, standards, and guidelines in 1990 congress enacted the americans with disabilities act (ada), the first comprehensive legislation mandating equal treatment under the law for pwd. the ada prohibits discrimination against pwd in employment, public services, public accommodations, and in telecommunications. title ii of the ada mandates that all state governments, local governments, and public agencies provide access for pwd to all of their activities, services, and programs. since school, public, and academic libraries are under the purview of title ii, they must “furnish auxiliary aids and services when necessary to ensure effective communication.”4 though predating widespread use of the internet, the law’s intent points toward the adoption and adaptation of appropriate technologies to allow persons with a variety of disabilities to access electronic resources in a way that is most effective for them. changes to section 508 of the 1973 rehabilitation act enacted in 1998 and 2000 introduced the first standards for “accessible information technology recognized by the federal government.”5 many state and local governments have since passed laws applying the standards of section 508 to government agencies and related services. according to the access board, the independent federal agency charged with assuring compliance with a variety of laws regarding services to pwd, information and communication technology (ict) includes any equipment or interconnected system or subsystem of equipment, that is used in the creation, conversion, or duplication of data or information. the term electronic r. todd vandenbark (todd.vandenbark@utah.edu) is web services librarian, eccles health sciences library, university of utah, salt lake city. 24 information technology and libraries | march 2010 and information technology includes, but is not limited to, telecommunications products (such as telephones), information kiosks and transaction machines, world wide web sites, multimedia, and office equipment such as copiers and fax machines.6 the access board further specifies guidelines for “web-based intranet and internet information and applications,” which are directly relevant to the provision of such services in libraries.7 what follows is a detailed examination of these standards with examples to assist in understanding and implementation. (a) a text equivalent for every non-text element shall be provided. assistive technology cannot yet describe what pictures and other images look like; they require meaningful text-based information associated with each picture. if an image directs the user to do something, the associated text must explain the purpose and meaning of the image. this way, someone who cannot see the screen can understand and navigate the page successfully. this is generally accomplished by using the “alt” and “longdesc” attributes for images: <img src=“image.jpg” alt=“short description of image.” longdesc=“explanation.txt” />. however, these aids also can clutter a page when not used properly. the current versions of the most popular screen-reader software do not limit the amount of “alt” text they can read. however, freedom scientific’s jaws 6.x divides the “alt” attribute into distinct chunks of 125 characters each (excluding spaces) and reads them separately as if they were separate graphics.8 this can be confusing to the end user. longer content can be put into a separate text file and the file linked to using the “longdesc” attribute. when a page contains audio or video files, a text alternative needs to be provided. for audio files such as interviews, lectures, and podcasts, a link to a transcript of the audio file must be immediately available. for video clips such as those on youtube, captions must accompany the clip. (b) equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. this means that captions for video must be real-time and synchronized with the actions in the video, not contained solely in a separate transcript. (c) web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. while color can be used, it cannot be the sole source or indicator of information. imagine an educational website offering a story problem presented in black and green print, and the answer to the problem could be deciphered using only the green letters. this would be inaccessible to students who have certain forms of color-blindness as well as those who use screen-reader software. (d) documents shall be organized so they are readable without requiring an associated style sheet. the introduction of cascading style sheets (css) can improve accessibility because they allow the separation of presentation from content. however, not all browsers fully support css, so webpages need to be designed so any browser can read them accurately. the content needs to be organized so that it can be read and understood with css formatting turned off. (e) redundant text links shall be provided for each active region of a server-side image map, and (f) client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. an image map can be thought of as a geometrically defined and arranged group of links to other content on a site. a clickable map of the fifty u.s. states is an example of a functioning image map. a server-side image map would appear to a screen reader only as a set of coordinates, whereas clientside maps can include information about where the link leads through “alt” text. the best practice is to only use client-side image maps and make sure the “alt” text is descriptive and meaningful. (g) row and column headers shall be identified for data tables, and (h) markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. correct table coding is critical. each table should use the “table summary” attribute to provide a meaningful description of its content and arrangement: <table summary=“concise explanation belongs here.”>. headers should be coded using the table header (“th”) tag, and its “scope” attribute should specify whether the header applies to a row or a column: <th scope=“col”> or <th scope=“row”>. if the table’s content is complex, it may be necessary to provide an alternative presentation of the information. it is best to rely on css for page layout, taking into consideration the directions in subparagraph (d) above. (i) frames shall be titled with text that facilitates frame identification and navigation. frames are a deprecated feature of html, and their use should be avoided in favor of css layout. (j) pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 hz and lower than 55 hz. lights with flicker rates in this range can trigger epileptic seizures. blinking or flashing elements on tending a wild garden: library web design for persons with disabilities | vandenbark 25 a webpage should be avoided until browsers provide the user with the ability to control flickering. (k) a text-only page, with equivalent information or functionality, shall be provided to make a web site comply with the provisions of this part, when compliance cannot be accomplished any other way. the content of the text-only page shall be updated whenever the primary page changes. complex content that is entirely visual in nature may require a separate text-only page, such as a page showing the english alphabet in american sign language. this requirement also serves as a stopgap measure for existing sites that require reworking for accessibility. some consider this to be the web’s version of separate-but-equal services, and should be avoided.9 offering a text-only alternative site can increase the sense of exclusion that pwd already feel. also, such versions of a website tend not to be equivalent to the parent site, leaving out promotions or advertisements. finally, a text-only version increases the workload of web development staff, making them more costly than creating a single, fully accessible site in the first place. (l) when pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology. scripting languages such as javascript allow for more interactive content on a page while reducing the number of times the computer screen needs to be refreshed. if functional text is not available, the screen reader attempts to read the script’s code, which outputs as a meaningless jumble of characters. using redundant text links avoids this result. (m) when a web page requires that an applet, plug-in, or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with [subpart b: technical standards] §1194.22(a) through (i). web developers need to ascertain whether a given plug-in or applet is accessible before requiring their webpage’s visitors to use it. when using applications such as quicktime or realaudio, it is important to provide an accessible link on the same page that will allow users to install the necessary plug-in. (n) when electronic forms are designed to be completed on-line, the form shall allow people using assistive technology to access information, field elements, and functionality required for completion and submission of the form, including all directions and cues. if scripts used in the completion of the form are inaccessible, an alternative method of completing the form must be made immediately available. each element of a form needs to be labeled properly using the <label> tag. (o) a method shall be provided that permits users to skip repetitive navigation links. persons using screen reader software typically navigate through pages using the tab key, listening as the text is read aloud. websites commonly place their logo at the top of each page and make this graphic a link to the site’s homepage. many sites also use a line of graphic images just beneath this logo on every page to serve as a navigation bar. to avoid having to listen through this same list of links on every page just to get to the page’s content, a “skip to content” link as the first option at the top of each page provides a simple solution to this problem. (p) when a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required. some sites log a user off if they have not typed or otherwise interacted with the page after a certain time period. users must be notified in advance that this is going to happen and given sufficient time to respond and request more time as needed. n standards-setting groups and their work one organization that seeks to move internet technology beyond basic section 508 compliance is the web accessibility initiative (wai) of the world wide web consortium (w3c). the mission of the wai is to develop n guidelines that are widely regarded as the international standard for web accessibility; n support materials to help understand and implement web accessibility; and n resources through international collaboration.10 the w3c published its first web content accessibility guidelines (wcag 1.0) in may of 1999 for making online content accessible to pwd. by following these guidelines, developers create web content that is readily available to every user regardless of the way it’s accessed. the wai provides ten quick tips for improving accessibility in website design: n images and animations. use the “alt” attribute to describe the function of each visual. n image maps. use the client-side map and text for hotspots. n multimedia. provide captioning and transcripts of audio, and descriptions of video. 26 information technology and libraries | march 2010 n hypertext links. use text that makes sense when read out of context. for example, avoid “click here.” n page organization. use headings, lists, and consistent structure. use css for layout and style where possible. n graphs and charts. summarize or use the “longdesc” attribute. n scripts, applets, and plug-ins. provide alternative content in case active features are inaccessible or unsupported. n frames. use the “noframes” element and meaningful titles. n tables. make line-by-line reading sensible. summarize. n check your work. validate. use tools, checklist, and guidelines at http://www.w3.org/tr/wcag.11 many libraries and other organizations have sought to follow wcag 1.0 since it was published. recently, the w3c updated their standards to wcag 2.0, and the wai website offers an overview of these guidelines along with a “customizable quick reference” designed to facilitate successful compliance. the principles behind 2.0 can be summarized by the acronym p.o.u.r. perceivable n provide text alternatives for non-text content. n provide captions and alternatives for multimedia. n make information adaptable and available to assistive technologies. n use sufficient contrast to make things easy to see and hear. operable n make all functionality keyboard accessible. n give users enough time to read and use content. n do not use content known to cause seizures. n help users navigate and find content. understandable n make text readable and understandable. n make content appear and operate in predictable ways. n help users avoid and correct mistakes. robust n maximize compatibility with current and future technologies.12 these guidelines offer assistance in creating accessible web-based materials. given their breadth, however, they raise concerns of overly wide interpretation and the strong possibility of falling short of section 508 standards. reading the details in wcag 2.0 does not give any additional assistance to library web developers on how to create a section 508–compliant website. clark points out that the three wcag 2.0 documents are long (72–165 pages), confusing, and sometimes internally contradictory.13 the goal of a library webmaster is to provide an interface (website, opac, database, and so on) that is both cutting-edge and accessible, and to encourage its use by patrons of all ability levels. while they have outlined a helpful rationale, the w3c’s overlong guidelines do little to help library web developers to achieve this goal. n recommendations libraries today typically offer three types of web-based resources: (1) access to the internet, (2) access to subscription databases, and (3) a library’s own webpage, all of which need to be accessible to pwd. libraries trying to comply with section 508 are required to “furnish auxiliary aids and services when necessary to ensure effective communication.”14 there are a number of options available to libraries on tight budgets. the first set involves the features built into each computer’s operating system and software. for some users with visual impairments, enlarging the font size of text and images on the screen will make electronic content more accessible. both macintosh and windows system software have universal-access capabilities built in, including the ability to read aloud text that is on the screen using synthesized speech. the mac read-aloud tool is called voice over; the windows read-aloud tool is called narrator. both systems allow for screen magnification. exploring and learning the capabilities of these systems to enhance accessibility is a free and easy first step for any library’s technology offerings, regardless of funding restrictions. libraries with more substantial technology budgets have a wide variety of hardware and software options to choose from to meet the needs of pwd. for patrons with visual impairments, several software packages are available to read aloud the content of a website or other electronic document using synthesized speech. jaws by freedom scientific and windoweyes by gw micro are two of the best-known software packages, and both include the ability to output to a refreshable braille display (which both companies also sell). kurzweil 3000 is an education-oriented software package that not only reads on-screen text aloud but has a wealth of additional tools to assist students with learning difficulties such as attention deficit disorder or dyslexia. it is designed to integrate with any education package as well as to assist students whose primary language is not english. persons with low vision needing screen magnification beyond the features windows offers may look to magic by freedom scientific or zoomtext by ai squared. some of these tending a wild garden: library web design for persons with disabilities | vandenbark 27 software companies offer free trial versions, have online demonstrations, or both. because prices for this software and related equipment can be high, it is prudent to first check with patrons with visual impairments and professionals in the field prior to making your purchase. humbert and stores, members of indiana university’s web accessibility team, offer accessibility evaluations of websites and other services at the university. when asked to compare windows and macintosh systems as to their usefulness in assisting pwd with web-based media, humbert rated the windows operating system superior, explaining that it has the proper “handles” coded into its software for screen readers and assistive technologies to grab onto. assistive technology software is more stable in windows vista because its predecessor, windows xp, “used hacked together drivers to display the information.”15 humbert discourages the use of vista and jaws on an older machine because vista is a memory hog and can crash jaws along with the rest of the system. the web browsers internet explorer and firefox allow the user to enlarge text and images on a webpage, though firefox is more effective. text can be enlarged only if the webpage being viewed is designed using resizable fonts. stores, who is profoundly visually impaired, uses jaws screen-reader software to work and to surf the web. she notes that both browsers work equally well with screenreader software.16 an important web-based resource that libraries provide is subscription databases. however, as one study has shown, “most librarians lack the time, resources and/or skills to evaluate the degree to which their library subscription databases are accessible to their disability communities.”17 the question is do the vendors themselves make an effort to produce an accessible product? a 2007 survey of twelve major database companies found that while most “have integrated accessibility standards/ guidelines into their search interfaces and/or plan to improve accessibility in future releases,” only five actually conducted usability studies with people who use assistive technology. a number of studies have found that “while most databases are functionally accessible, companies need to do more to meet the needs of the disability community and assure librarians of the accessibility of their products.”18 subscription databases can be inaccessible to pwd in the display of search results and accompanying information. the three most common forms of results delivery are html full text, html full text with graphics, and pdf files. pdf files are notoriously inaccessible to persons using screen readers. while adobe has made significant strides in rendering pdfs accessible, many databases contain numerous pdf documents created in versions of adobe acrobat prior to version 5.0 (released in 2001), which are not properly tagged for screen readers. even newer pdf documents are only as accessible as their tagging allows. journal articles received from publishers may or may not be properly tagged, so database companies cannot guarantee that their content is fully accessible. one vendor that is avoiding this trap is jstor. using optical character recognition (ocr) software, jstor delivers image-based pdfs with embedded text to make their content available to screen readers.19 librarians must insist that database packages be accessible and compatible with the forms of assistive technology most frequently used by their patrons, both in-house and online. one tool used to evaluate database (or other product) accessibility is the voluntary product accessibility template (vpat). created in partnership between the information technology industry (iti) council and the u.s. general services administration (gsa) in 2001, it provides “a simple, internet-based tool to assist federal contracting and procurement officials in fulfilling the new market research requirements contained in the section 508 implementing regulations.”20 vpat is a voluntary disclosure form arranged in a series of tables listing the criteria of relevant subsections of section 508 discussed previously. blank cells are provided to allow company representatives to describe how their product’s supporting features meet the criteria and to provide additional detailed information. library personnel can request that vendors complete this form to document which subsections of section 508 their products meet, and how. to be most useful, the form needs to be completed by company representatives with both a clear understanding of section 508 and its technical details and thorough knowledge of their product. knowledgeable library staff are encouraged to verify the quality and accuracy of the information provided before purchasing. like databases, a library’s website needs to be accessible to patrons with a variety of needs. according to muncaster, accessible sites are 35 percent easier for everyone to use and are more likely to be found by internet search engines.21 fully accessible websites are simpler to maintain and are on average 50 percent smaller than inaccessible ones, which means they download faster, making them easier to use.22 in creating a basic site, current best practice has been to render the content in html or xhtml and design the layout using css. this way, if it is discovered the site’s pages are not fully accessible, a simple change to the css updates all pages, saving the site manager time and effort. finally, creating an accessible site from the beginning is substantially easier than retrofitting an old one. a complete rebuild of a library website is an opportunity to improve accessibility. reynolds’ article on creating a user-centered website for the johnson county (kans.) library offers an example of how libraries can apply basic information architecture design principles on a budget. johnson county focused on simple, low-budget 28 information technology and libraries | march 2010 usability studies involving patrons in the selection of site navigation categories, designing the layout, and testing the resulting user interface. by involving average users in this process, this library was able to achieve substantial improvements in the site’s usability. prior to the redesign, usability testing determined that 42 percent of users were not successful in finding information on the library’s old site. after the redesign, “only 4% of patrons were unsuccessful in finding core-task information on the first attempt.”23 even so, a quick test of the site with the online accessibility evaluation tool cynthiasays indicates that it still does not fully meet the requirements of section 508. had the library’s staff included pwd in their process, the demonstrated degree of improvement might have allowed them to meet and possibly exceed this standard. an understanding of how a person with disabilities experiences the online environment can help point the way toward improved accessibility. a recent study in the united kingdom tracked the eye movements of ablebodied computer users in an effort to answer these questions. researchers asked eighteen people with normal or corrected vision to search for answers on two versions of a bbc website—the standard graphical page and the textonly version. subjects’ eyes tended to dart around the standard page “as they attempt to locate what appears visually to be the next most likely location”24 for the answer. but in searching the text-only page, subjects went line-by-line, making smaller jumps across each page. researchers determined that the webpage and its layout serve as a form of external memory, providing visual cues to the structure of its content and how to navigate it. if the internet is an information superhighway, then the layout of a standard webpage serves as the borders and directional signs for browsing. the visual cues and navigation aids inherent in current webpages’ layouts provide no auditory equivalent for presentation to people with visual impairments. information seeking on the web is a complex process requiring “the ability to switch and coordinate among multiple information-seeking strategies” such as browsing, scanning, query-based searching, and so on.25 if web browsers could translate formatting and presentation into audio tailored to the needs of the visually impaired, the use of the internet would be a far more satisfying experience for those users. however, such web programming would require years of additional research and development. in the meantime, web librarians must strive to build sites that are clean, hierarchical, and usable by all persons by following to the standards and guidelines currently available. one way to enhance the accessibility of sites is to follow a database-driven web development model. in addition to using xhtml and css, dunlap recommends that content be stored in a relational database such as mysql and that a coding language such as php be used to create pages dynamically. this approach has two advantages. first, it allows for the creation of “a flexible website design style that lives in a single, easily modified file that controls the presentation of every web page of the site.”26 second, it requires far less time for site maintenance, freeing staff to devote time to assuring accessibility while accommodating changes in web technology. such a model can be used by database vendors to ensure that their services can seamlessly integrate with the library’s online content. use of mobile phones and similar devices to browse the web is at an all-time high, and content providers are eager to make their sites mobile-friendly. many of these end users experience similar barriers to accessing this content as pwd do. for example, persons with some motor disabilities as well as mobile phones with only a numeric keypad cannot access sites with links requiring the use of a mouse. sites that follow either the w3c’s mobile web best practices (mwbp) or wcag are well on their way to meeting both standards.27 by properly associating labels with their controls, internet content can be made fully accessible to both end users. understanding the similarities between mwpb and wcag can lead to website design that is truly perceivable, operable, understandable, and robust. n summary librarians with responsibility for web design and technology management operate in an evolving environment. legal requirements make clear the expectation to serve the wide variety of needs of patrons with disabilities. yet the guidelines and standards available to assist in this venture range from complex to vague and insufficient. assistive technologies continue to improve with many traditional vendors confident that their products are accessible. in actual use, however, substantial challenges and shortcomings remain. the challenge for technology librarians is to be proactive in keeping abreast of technological advances, to experiment and learn from their efforts, and to continually update and adapt to provide web or hypermedia information and services to patrons of all kinds. references 1. united nations, convention on the rights of persons with disabilities, 2008, http://www.un.org/disabilities/default .asp?navid=12&pid=150 (accessed aug. 10, 2009).

lierman, and cherie turner information technology and libraries | march 2016 7 abstract the university of houston libraries implemented primo as the primary search option on the library website in may 2014. in may 2015, the libraries released a redesigned interface to improve user experience with the tool. the libraries took a user-centered approach to redesigning the primo interface, conducting a “think-aloud” usability test to gather user feedback and identify needed improvements. this article describes the method and findings from the usability study, the changes that were made to the primo interface as a result, and implications for discovery-system vendor relations and library instruction. introduction index-based discovery systems have become commonplace in academic libraries over the past several years, and academic libraries have invested a great deal of time and money into implementing them. frequently, discovery platforms serve as the primary access point to library resources, and in some libraries they have even replaced traditional online public access catalogs. because of the prominence of these systems in academic libraries and the important function that they serve, libraries have a vested interest in presenting users with a positive and seamless experience while using a discovery system to find and access library information. libraries commonly conduct user testing on their discovery systems, make local customizations when possible, and sometimes even change products to present the most user-friendly experience possible. university of houston libraries has adopted new discovery technologies as they became available in an effort to provide simplified discovery and access to library resources. as a first step, the libraries implemented innovative interface’s encore, a federated search tool, in 2007. when index-based discovery systems became available, the libraries saw them as a way to provide an improved and intuitive search experience. in 2010, the libraries implemented serials solutions’ summon. after three years and a thorough process of evaluating priorities and investigating alternatives, the libraries made the decision to move to ex libris’ primo, which was done in may of 2014. the libraries’ intention was to continually assess and customize primo to improve functionality and user experience. the libraries conducted research and performed user testing, and in may kelsey brett (krbrett@ua.edu) is discovery systems librarian, ashley lierman (arlierman@uh.edu) is instructional design librarian, and cherie turner (ckturner2@uh.edu) is chemical sciences librarian, university of houston libraries, houston, texas. mailto:krbrett@ua.edu mailto:arlierman@uh.edu mailto:ckturner2@uh.edu lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 8 2015 a redesigned primo search results page was released. one of the activities that informed the primo redesign was a “think-aloud” usability test that required users to complete a set of two tasks using primo. this article will present the method and results of the testing as well as the customizations that were made to the discovery system as a result. it will also discuss some broader implications for library discovery and its effect on information literacy instruction. literature review there is a substantial body of literature discussing usability testing of discovery systems. in the interest of brevity, we will focus solely on studies and overviews involving primo implementations, from which several patterns have emerged. multiple studies have indicated that users’ responses to the system are generally positive; even in testing of very early versions by a development partner users responded positively overall.1 interestingly, some studies found that in many cases users rated primo positively in post-testing surveys even when their task completion rate in the testing had been low.2 multiple studies also found evidence that, although users may struggle with primo initially, the system is learnable over time. comeaux found that the time it took users to use facets or locate resources decreased significantly with each task they performed,3 while other studies saw the use of facets per task increase for each user over the course of the testing.4 user reactions to facets and other post-limiting functions in primo were divided. in one of the earliest studies, sadeh found that users responded positively to facets,5 and some authors found users came to use them heavily while searching,6 while others found that facets were generally underused.7 multiple studies found that users tended to repeat their searches with slightly different terms rather than use post-limiting options.8 thomsett-scott and reese, in a survey of the literature on discovery tools, reported evidence of a trend that users reacted more positively to post-limiting in earlier discovery studies,9 while the broader literature shows more negative reactions in more recent studies. this could indicate that shifts in the software, user expectations, or both may have decreased users’ interest in these options. a few specific types of usability problems seem common across tests of primo and other discovery systems. across a large number of studies, it has been found that users—especially undergraduate students—struggle to understand library and academic terminology used in discovery. some terminology changes were made after users had difficulty in the earliest usability tests of primo,10 but users continued to struggle with terms like hold and recall in item records.11 users also failed to understand the labels of limiters,12 and they also failed to recognize the internal names of repositories and collections.13 literature reviews on discovery systems have found terminology to be a common stumbling block for searchers across a wide number of individual studies.14 similarly, users often struggle to understand the scope of options available to them when searching and the holdings information in item records. users failed in multiple tests to distinguish between the article level and the journal level,15 could not interpret bibliographic information technology and libraries | march 2016 9 information sufficiently to determine that they had found the desired item,16 and chose incorrect options for scoping their searches.17 many studies found that users were unable to distinguish between multiple editions of a held item when all item types or editions were listed in the record.18 in other cases, users had difficulty interpreting locations and holdings information for physical items.19 among the needs and desires expressed by and for primo users in the literature, two in particular stand out. first, many users expressed a desire for more advanced search options; some wanted more complexity in certain facets and the ability to search within results,20 while other users simply wanted an advanced search option to be available.21 secondly, a large number of studies indicated that instruction on primo or other discovery systems was needed for users to search effectively. in some cases this was the conclusion of the researchers conducting the study,22 while in other cases users themselves either suggested or requested instruction on the system.23 it is also worth noting that it has been questioned whether usability testing as a whole is a sufficient mechanism for evaluating discovery-system functionality. prommann and zhang found that usability testing has focused almost exclusively on the technical functioning of the software and not adequately revealed the ability of discovery systems like primo to successfully complete users’ desired tasks.24 they proposed hierarchical task analysis (hta) as an alternative, to examine users’ most frequent desires and the capacity of discovery systems to meet them. prommann and zhang acknowledged, however, that as hta is completed by an expert on the system rather than by an actual user, some of the valuable information derived from usability testing (including terms and functions that users do not understand, however well-designed) is lost in the process; they concluded that a combination of the two systems of testing is ideal to retain the best of both. background at the university of houston libraries, the resource discovery systems department (rds) is responsible for the maintenance and development of primo. however, it is important to rds to gather feedback and foster buy-in from stakeholders in the library before making changes to the system. to that end, rds works with two committees to assess the system and make recommendations for its improvement. the discovery usability group and the discovery advisory group include members from public services, technical services, and systems; each member brings a unique perspective on discovery. the discovery usability group is charged with assessing the discovery system through a variety of methods including usability testing, focus groups, and user interviews. the discovery advisory group reviews results of user testing and makes recommendations for improvement. all changes to the discovery system are reviewed by the groups before they are released for public use. lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 10 in fall 2014, several months after the primo implementation, the discovery usability group conducted a focus group with student workers from the library’s information desk (a dual reference and circulation desk) to solicit feedback about the functionality of primo and suggestions for its improvement. in the meantime, the discovery advisory group was testing primo and evaluating primo sites at peer and aspirational institutions. the groups used the information collected through the focus group and research on primo to make recommendations for improvement. rds has access to a primo development sandbox, and many of the recommended changes were made in the sandbox environment and reviewed by the two groups prior to public release. changes to the search box can be seen in figure 1. rarely used tabs were replaced with a dropdown menu to the right of the search box to allow users to limit to “everything,” “books+,” or “digital library.” to increase visibility, links to “advanced search” and “browse search” were made larger and more spacing was added. live site: development sandbox: figure 1. search box in live site (above) and development sandbox (below) at time of testing changes were also made to create a cleaner and less cluttered search results page (see figure 2). more white space was added, and the links (or tabs) to “view online,” “request,” “details,” etc., were redesigned and renamed for clarity. for example, the “view online” link was renamed to “preview online” because it opens a box within the search results page that displays the item. the groups believed “preview online” more accurately represents what the link does. information technology and libraries | march 2016 11 live site: development sandbox: figure 2. search results in live site (above) and development sandbox (below) at time of testing the facets were also redesigned to look cleaner and larger to attract users’ attention (see figure 3). lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 12 live site: development sandbox: figure 3. facets in live site and development sandbox at time of testing both groups were happy with the changes to the primo development sandbox but wanted to test the effect of the changes on user search behavior before updating the live site. the discovery usability group conducted a usability test within the development sandbox. the goal of the test was to find out if users could effectively complete common research tasks using primo. with that goal in mind, the group developed a usability test and conducted it during the spring semester of 2015. information technology and libraries | march 2016 13 methodology the discovery usability group developed a usability test using a “think-aloud” methodology, where users were asked to verbalize their thought process as they completed research tasks through primo. four tasks were designed to mirror tasks that users are likely to complete for class assignments or for general research. to minimize the testing time, each participant completed two tasks, with the facilitators alternating between two sets of tasks from one participant to the next. test 1 task 1: you are trying to find an article that was cited in a paper you read

(2013). expanding our vision for the arts in education. harvard educational review, 83(1), 5–14. please find this article using onesearch [the public-facing name given to the libraries’ primo implementation]. task 2: you are doing a research project on the effects of video games on early childhood development. find a peer-reviewed article on this topic, using onesearch. test 2 task 1: recently your friend recommended the book the lighthouse by p. d. james. use onesearch to find out if you can check this book out from the library. task 2: you are writing a paper about the drug cartels’ influence on mexico’s relationship with the united states. find a newspaper article on this topic, using onesearch. two facilitators set up a table with a laptop in the front entrance of the library. they alternated between the facilitator and note-taker roles. another group member took on the role of “caller” and recruited library patrons to participate in the study. the caller set up a table visible to those passing by with library-branded t-shirts and umbrellas to incentivize participation. the caller explained what would be expected of the potential participant and went over the informedconsent document. after signing the form, the participant performed two tasks. after the test the participant received a library t-shirt or umbrella, and snacks. the facilitators used morae usability software to record the screen and audio of each test. participants were asked for permission to record their sessions, but could opt out. during the three hour testing period, fifteen library patrons participated in the study, and fourteen sessions were recorded. of the fifteen participants, thirteen were undergraduate students (four freshman, one sophomore, seven juniors, and two seniors), one was a graduate student, and one was a postbaccalaureate student. the majority of the participants were from the sciences, along with two students from the college of business and two from the school of communications. there were no participants from the humanities. lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 14 the facilitators took notes on a rubric (see table 1) that simplified the processes of coding and reviewing the recordings. after the usability testing, the facilitators reviewed the notes and recordings, coded them for common themes and breakdowns, and prepared a report of their findings and design recommendations. the facilitators sent the report, along with audio and screen recordings, to the discovery advisory group, who reviewed them along with rds. the discovery advisory group made additional design recommendations, and rds used the information and recommendations to implement additional customizations to the primo development sandbox. preliminary questions ask: what is your affiliation with the university of houston? year? major? ask: how often do you use the library website? for what purpose(s)? task 1 describe the steps the participant took to complete the task s/u ask: how did you feel about this task? what was simple? what was difficult? ask: is there anything that would make completing this task easier? task 2 describe the steps the participant took to complete the task s/u ask: how did you feel about this task? what was simple? what was difficult? ask: is there anything that would make completing this task easier? follow-up question ask: what can we do to improve the overall experience using onesearch? table 1. task completion rubric for test 1 information technology and libraries | march 2016 15 results test 1, task 1 you are trying to find an article that was cited in a paper you read recently. you have the following citation: clapp, e., & edwards, l.

sophistication and efficiency varied between participants. some searched by the authors’ last names, which was not specific enough to return the item in question. four participants attempted to use advanced search or the drop-down menu to the right of the search box to pre-filter their results. two participants viewed the options in the drop-down menu, which were “everything,” “books+,” and “digital library,” and left it on the default “everything” search. when prompted, the participants explained that they were expecting the drop-down to contain title and/or author limiters. similarly, participants expected an author limiter in the advanced search. the citation format seemed to confuse participants, and they tended to search for the piece of information that was listed first—the authors—rather than the most unique piece of information—the title. if the first search did not return the correct item in the first few results, the participant would modify their search by searching for a different element of the citation or adding another element of the citation to the initial search until the item they were looking for appeared as one of the first few results. participant 5 thought they had successfully completed the lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 16 task, but the facilitator had to point out that the item they chose did not meet the citation exactly, and on the second try they found the correct item. participant 2 worked on the task for more than four minutes, significantly longer than the other seven participants. they immediately navigated to advanced search and filled out several fields in the advanced search form with the elements of the citation. if the search did not return their item, they added more elements until they finally found it. simply searching the title in the citation would have returned the item as the first search result. filling out the advanced search form with all of the information from the citation does not necessarily increase a user’s chances of finding the item in a discovery system, though it might do so when searching in an online catalog or subject database. the discovery advisory and usability groups made two recommendations to address some of the identified issues: include an author search option in the advanced search, and add an “articles+” option to the drop-down menu on the basic search. rds implemented both recommendations. the discovery usability group identified confusion around citations as a common breakdown during this task. the groups recommended providing instructional information about searching for known items to address this breakdown; however, rds is still working on an effective method to provide this information in a simple and visible way. test 1, task 2 you are doing a research project on the effects of video games on early childhood development. find a peer-reviewed article on this topic, using onesearch.

task 2 all eight participants successfully found an article on this topic, but were less successful in determining whether the article was peer-reviewed. only one participant used the “peer-reviewed information technology and libraries | march 2016 17 journals” facet without being prompted. three users noticed the “[peer-reviewed journal]” note in the record information for search results, and used it to determine if the article was peer-reviewed. one participant went to the full-text of an article, and said it “seemed” like it was peer-reviewed and considered the task complete. the resource type facets were more heavily used during this task than the “peer-reviewed journals” facet, despite its being promoted to the top of the list of facets. two participants used the “articles” facet, and two participants used the “reviews” facet, thinking it limited to peer-reviewed articles. participants 3 and 8 needed help from the facilitator to determine whether a source was peer-reviewed. there was an overall misunderstanding of what peer-reviewed means, which affected participants’ confidence in completing the task. the design recommendations based on this task included changing the “peer-reviewed journals” facet to “peer-reviewed articles” or simply, “peer-reviewed.” rds changed the facet to “peerreviewed articles” to help alleviate confusion. additionally, the groups recommended emphasizing the “[peer-reviewed journal]” designations within the search results and providing a method for limiting to peer-reviewed materials before conducting a search. customization limitations of the system have prevented rds from implementing these design recommendations yet. a way to address the breakdowns caused by misunderstanding terminology also has yet to be identified. it was disheartening that participants did not use the “peer-reviewed journals” facet despite its being purposefully emphasized on the search results page. test 2, task 1 recently your friend recommended the book the lighthouse by p. d. james. use onesearch to find out if you can check this book out from the library. participant time on task task completion 1 1m 7s y 2 56s y 3 no

once they found it. for this task every participant searched by title and found the book as the first search result. four users limited to “books+” before searching using the drop-down lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 18 menu, while the other three remained in the default “everything” search. only one participant used the locations tab within the search results to determine availability; the others clicked the title and went to the item’s catalog record. all participants were able to determine that the book was available in the library, but there was an overall lack of understanding about how to use the information in the catalog to check out a book. participant 1 said that they would write down the call number, take it to the information desk, and ask how to find it, which was the most sophisticated response of all seven participants. participant 4 spent nearly two minutes clicking through links in the opac expecting to find a “check out” button and only stopped when the facilitator stepped in. a recommended design change based on this task was to have call numbers in primo and the online catalog link to a stacks guide or map. this is a feature that may be developed in the future, but technical limitations prevented rds from implementing it in time for the release of the redesigned search interface. like the previous tasks, some of the breakdowns occurred because of a lack of understanding of library services. users easily figured out that there was a copy of the book in the library, but had little sense of what to do next. none of the participants successfully located the stacks guide or the request feature that would put the item on hold for them. steps should be taken to direct users to these features more effectively. test 2, task 2 you are writing a paper about the drug cartels’ influence on mexico’s relationship with the united states. find a newspaper article on this topic, using onesearch. participant time on task task completion 1 4m 45s y (required assistance) 2 59s y 3 no recording n 4 7m 47s y 5 2m 52s y 6 1m 33s y 7 1m 30s y table 5. results for test 2, task 2 this task was difficult for participants. two users limited their search initially to “digital library” using the drop-down menu, thinking it would be a place to find newspaper articles; their searches returned zero results. only two users used the “newspaper articles” facet without being prompted, and users did not seem to readily distinguish newspaper articles as a resource type. participants information technology and libraries | march 2016 19 did not notice the resource type icons without being prompted. several participants needed to be reminded that the task was to find a newspaper article, and not any other type of article. with guidance, most participants were able to complete the task. participant 4 remained on the task for almost eight minutes because of their dissatisfaction with the relevancy of the results to the prompt. interestingly, they found the “newspaper articles” facet and reapplied it after each modified search, suggesting that they learned to use system features as they went. one of the recommendations based on this task was to remove “digital library” as an option in the drop-down menu on the basic search. it was evident that “digital library” did not have the same meaning to end users as it does to internal users. this recommendation was easily implemented. another recommendation was to emphasize the resource type icons within the search results, but we have not determined a way to do so effectively. one suggestion from the discovery usability group was to exclude newspaper articles from the search results as a default, but no consensus was reached on this issue. limitations the discovery usability group identified limitations to the usability test that should be noted. testing was done in a high-traffic portion of the library’s lobby, which is used as study space by a broad range of students. participants were recruited from this study space, and we chose not to screen participants. the fifteen participants in the study did not constitute a representative sample. almost all participants were undergraduate students, and no humanities majors participated. the outcomes might have been different if our participants had included more experienced researchers or students from a broader range of disciplines. by adding screening questions or choosing a more neutral location, we would have limited the number of participants who could complete our testing. another limitation was that the participants started the usability test within the primo interface. because primo is integrated into the libraries’ website, users would typically begin searching the system from within the library homepage. the goals of the study required testing of our primo development sandbox, which was not yet available to the public, and therefore could not be accessed in the same way. this gave participants some additional options from the initial search pages that are not usually available through the main search interface. while testing an active version of the interface would be preferable, one of our goals was to understand how our modifications affected user behavior, so testing the unmodified version was not an acceptable substitute. additionally, the usability study presented tasks out of context and did not replicate a true user-searching experience. despite the limitations, we learned valuable lessons from the participants in this study. discussion users successfully completed the tasks in this usability study. unfortunately, they did not take advantage of many of the features that can make such tasks easier—particularly facets. this was lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 20 especially apparent when we asked users to find a peer-reviewed journal article (test 1, task 2). primo has a facet that will limit a search to only peer-reviewed journal articles, and only one out of eight participants used this facet during this task. participants appreciated the pre-search filtering options, and requested more of them (such as an author search), while post-search facets were underutilized. similarly, participants almost uniformly ignored the links, or tabs, within the search results, which would provide users with more information, a preview of the full-text, and additional features such as an email function. users bypassed these options and clicked on the title instead. the discovery usability group theorized that users clicked on the title of the item because that behavior would be successful in a more familiar search interface like google. the team customized the configuration so that a title click would open either the full-text of electronic items or the catalog record for physical items to accommodate users’ instinctive search behaviors. the tabs, though a prominent feature of the discovery system, have proved to have little value for users. throughout the implementation of discovery systems in academic libraries, both research studies and anecdotal evidence have suggested that users do not find end-user features like facets valuable; however, discovery system vendors have made no apparent attempt to reimagine the possibilities for search refinements. indeed, most of the findings in this study will present few surprises to anyone familiar with the discovery usability literature, which is itself concerning. as our literature review has shown, many of the same general usability issues have repeated throughout studies of primo since 2008, and most are very similar to usability issues in other, competitor discovery systems. this raises some concerns about the pace of innovation in the discovery field, and whether discovery vendors are genuinely taking into account the research findings about the needs of our users as they refine their products. in a recent article, david nelson and linda turney identified many issues with discovery facets in their current form that may be barriers to usage, particularly labeling and library jargon; we join them in urging vendors and libraries to collaborate more closely for deep analysis of actual facet usage by users, and to address those factors that have negatively affected facets’ value.25 during our usability study, a common barrier to the successful completion of a task was not the technology itself but a lack of understanding of the task. participants had difficulty deciphering a citation, which may have led to their tendency to search for a journal article by author and not by title. many participants struggled with using call numbers, and how to find and check out books in the library. peer review also proved to be a difficult or unfamiliar concept for many; when looking for peer-reviewed articles, some participants clicked on the “reviews” facet, which limited their searches to an inappropriate resource type. additionally, participants did not differentiate between journal articles and newspaper articles, which may indicate a broader inability to differentiate between scholarly and nonscholarly resources. this effect may be exaggerated by the high percentage of science students who participated, as these students may not have frequent need for newspaper articles. all of these challenges, however, are indicative of a deeper problem information technology and libraries | march 2016 21 with terminology. regardless of how simple it is to limit a search to peer-reviewed articles, a user who does not understand what peer review means cannot complete the task with confidence or certainty. librarians struggle with presenting understandable language and avoiding library terminology; as we discovered, academic language, like “peer-reviewed” and “citation,” presents a similar problem. these are not issues that can be resolved with a technological solution. rather, we join previous authors in suggesting that instruction may be a reasonable way to address many usability issues in primo. from our findings and from those in the wider literature, we conclude that general instruction in information literacy is prerequisite for effective use of this or any research tool, particularly for undergraduates. nichols et al. “recommend studying how to effectively provide instruction on primo searching and results interpretation,”26 but instruction on the use of a single tool is of limited utility to students in their academic lives. instead libraries could bolster information literacy instruction on key concepts around the production and storage of information, scholarly communications, and differences in information types. teaching these concepts effectively should help to alleviate the most common user issues, including understanding terminology and different types of information, as well as helping students to understand key elements of research in general. this is a particularly important point to note for librarians working as advocates for information literacy instruction, especially in cases where administrators or faculty may feel that more advanced tools, like discovery systems, should make instruction obsolete. conclusion several changes were made to the primo interface in response to breakdowns identified during the usability study. resource discovery systems first implemented the changes to the primo development sandbox. after the discovery usability and advisory groups agreed on the changes, they were made available on the live site (see figure 4). the redesigned search results page became available to the general public between the spring and summer academic sessions of 2015. in addition to the changes that were made because the usability study, rds made changes to the look and feel to make the search results interface more aesthetically pleasing and more in line with the university of houston brand. lessons learned: a primo usability study | brett, lierman, and turner doi: 10.6017/ital.v35i1.8965 22

instructional curriculum development discussions. references 1. tamar sadeh, “user experience in the library: a case study,” new library world 109, no. 1/2 (2008): 7–24, doi:10.1108/03074800810845976.

is information technology expert, software unit, information technology department; betsy simpson is chair, cataloging and metadata department; and doug smith is head, copy cataloging unit, cataloging and metadata department, george a. smathers libraries, university of florida, gainesville. michael jay, betsy simpson, and doug smith catqc and shelf-ready material: speeding collections to users while preserving data quality libraries contract with vendors to provide shelf-ready material, but is it really shelf-ready? it arrives with all the physical processing needed for immediate shelving, then lingers in back offices while staff conduct itemby-item checks against the catalog. catqc, a console application for microsoft windows developed at the university of florida, builds on oclc services to get material to the shelves and into the hands of users without delay and without sacrificing data quality. using standard c programming, catqc identifies problems in marc record files, often applying complex conditionals, and generates easy-to-use reports that do not require manual item review. a primary goal behind improvements in technical service workflows is to serve users more efficiently. however, the push to move material through the system faster can result in shortcuts that undermine bibliographic quality. developing safeguards that maintain sufficiently high standards but don’t sacrifice productivity is the modus operandi for technical service managers. the implementation of oclc’s worldcat cataloging partners (wcp, formerly promptcat) and bibliographic record notification services offers an opportunity to retool workflows to take advantage of automated processes to the fullest extent possible, but also requires some backroom creativity to assure that adequate access to material is not diminished. n literature review quality control has traditionally been viewed as a central aspect of cataloging operations, either as part of item-byitem handling or manual and automated authority maintenance. how this activity has been applied to outsourced cataloging was the subject of a survey of academic libraries in the united states and canada. a total of 19 percent of libraries in the survey indicated that they forgo quality control of outsourced copy, primarily for government documents records. however, most respondents reported they review records for errors. of that group, 50 percent focus on access points, 30 percent check a variety of fields, and a significant minority—20 percent—look at all data points. overall, the libraries expressed satisfaction with the outsourced cataloging using the following measures of quality supplied by the author: accuracy, consistency, adequacy of access points, and timeliness.1 at the inception of oclc’s promptcat service in 1995, ohio state university libraries participated in a study to test similar quality control criteria with the stated goals of improving efficiency and reducing copyediting. the results were so favorable that the author speculated that promptcat would herald a future where libraries can “reassess their local practices and develop greater confidence in national standards so that catalog records can be integrated into local opacs with minimal revision and library holdings can be made available in bibliographic databases as quickly as possible.”2 fast forward a few years and the new incarnation of promptcat, wcp, is well on its way to fulfilling this dream. in a recent investigation conducted at the university of arkansas libraries, researchers concluded that error review of copy supplied through promptcat is necessary, but the error rate does not warrant discontinuance of the service. the benefits in terms of time savings far outweigh the effort expended to correct errors, particularly when the focus of the review is to correct errors critical to user access. while the researchers examined a wide variety of errors, a primary consideration was series headings, particularly given the problems cited in previous studies and noted in the article.3 with the 2006 announcement by the library of congress (lc) to curtail its practice of providing controlled series access, the cataloging community voiced great concern about the effect of that decision on user access.4 the arkansas study determined that “the significant number of series issues overall (even before lc stopped performing series authority work) more than justifies our concern about providing series authority control for the shelf-ready titles.” approximately one third of the outsourced copy across the three record samples studied had a series, and, of that group, 32 percent needed attention, predominantly taking the form of authority record creation with associated analysis and classification decisions.5 the overwhelming consensus among catalogers is that error review is essential. as far as can be determined, an underlying premise behind such efforts seems to be that it is done with the book in hand. but could there be a way to satisfy the concerns without the book in hand? certainly, validation tools embedded in library management systems provide protections whether records are manually entered or batchloaded, and outsourced authority maintenance services (for those who can use them) offer further control. but a customizable tool that allows libraries to target specific needs, both standards-based and local, without relying on item-by-item handling can contribute michael jay (emjay@ufl.edu) is information technology expert, software unit, information technology department; betsy simpson (betsys@uflib.ufl.edu) is chair, cataloging and metadata department; and doug smith (dougsmith@uflib.ufl .edu) is head, copy cataloging unit, cataloging and metadata department, george a. smathers libraries, university of florida, gainesville. 42 information technology and libraries | march 2009 to an economy of scale demanded by an environment with shrinking budgets and staff to devote to manual bibliographic scrutiny. if that tool is viewed as part of a workflow stream involving local error detection at the receiving location as well as enhancement at the network level (i.e., oclc’s bibliographic record notification service), then it becomes an important step in freeing catalogers to turn their attention to other priorities, such as digitized and hidden collections. n local setting and workflow the george a. smathers libraries at the university of florida encompasses six branches that address the information needs of a diverse academic research campus with close to fifty thousand undergraduate and graduate students. the technical services division, which includes the acquisitions and licensing department and the cataloging and metadata department, acquires and catalogs approximately forty thousand items annually. seeking ways to minimize the handling of incoming material, beginning in 2006 the departments developed a workflow that made it possible to send shelf-ready incoming material directly to the branches after check-in against the invoice. shelf-ready items represent approximately 30 percent of the libraries’ purchased monographic resources at this time. by using wcp record loads along with vendor-supplied shelf-ready processing, the time from receipt to shelf has been reduced significantly because it is no longer necessary to send the bulk of the shipments to cataloging and metadata. exceptions to this practice include specific categories of material that require individual inspection. the vendor is asked to include a flag in books that fall into many of these categories: n any nonprocessed book or book without a spine label n books with spine labels that have numbering after the date (e.g., vol. 4, no. 2) n books with cds or other formats included n books with loose maps n atlases n spiral-bound books n books that have the words “annual,” “biennial,” or a numeric year in the title (these may be a serial add to an existing record or part of a series that will be established during cataloging) to facilitate a post–receipt record review for those items not sent to cataloging and metadata, acquisitions and licensing runs a local programming tool, catqc, which reports records containing attributes cataloging and metadata has determined necessitate closer examination. figure 1 is an example of the reports generated, which are viewed using the mozilla firefox browser. copy catalogers rotate responsibility for checking the report and revising records when necessary. retrieval of the physical piece is only necessary in the 1 percent of cases where the item needs to be relabeled. n catqc report catqc analyzes the content of the wcp record file and identifies records with particular bibliographic coding, which are used to detect potential problems: 1. encoding levels 2, 3, 5, 7, e, j, k, m 2. 040 with non-english subfield b 3. 245 fields with subfields h, n, or p 4. 245 fields with subfields a or b that contain numerals 5. 245 fields with subfields a or b that contain red flag keywords 6. 246 fields 7. 490 fields with first indicator 0 8. 856 fields without subfield 3 9. 6xx fields with second indicators 4, 5, 6, and 7 the numbers following each problem listed below indicate which codes are used to signal the presence of a potential problem. minimal-level copy (1) the library’s wcp profiles, currently in place for three vendors, are set up to accept all oclc encoding levels. with such a wide-open plan, it is important to catch records with minimal-level copy to assure that appropriate access points exist and are coded correctly. the library encounters these less-than-full encoding levels infrequently. parallel records (2) catqc identifies foreign library records that are candidates for parallel record treatment by indicating in the report if the 040 has a non-english subfield b. the report includes a 936 field if present to alert catalogers that a parallel record is available. volume sets (3, 4, 5) the library does not generally analyze the individual volumes of multipart monographic sets (i.e., volume sets) even when the volumes have distinctive titles. these catcq and shelf-ready material | jay, simpson, and smith 43 “volume,” “part,” and “number” as well as common abbreviations of those words (e.g., v. or vol.). serial vs. monograph treatment (4, 5) titles owned by the library and classified as serials sometimes are ordered inadvertently as monographs, resulting in the delivery of a monographic record. a similar problem also occasionally arises with new titles. by detecting numerals, keywords, or the presence of one or more of the subfields in the 245 field, we can quickly scan a list of records with these characteristics. of course, most of the records detected by catqc are false hits because of the broad scope of the search; however, it takes only a few minutes to scan through the record list. non-print formats (3) the library does not receive records for any format other than print through wcp. consequently, detecting the presence of a subfield h in the 245 field is a good signal that there may be a problem with the record. alternate titles (6) alternate titles can be an important access point for library users. sometimes text that should properly be in subfield i (e.g., “at head of title”) of the 246 field is placed in subfield a in front of the alternate title. this adversely affects user access to the title through browse searching. catqc checks for and reports the presence of a 246 field. the cataloger can then quickly confirm that it is coded correctly. untraced series (7) as a program for cooperative cataloging (pcc) participant, the library opted to follow pcc practice to continue to trace series despite lc’s decision in 2006 to treat as untraced all series statements in newly cataloged records. because some libraries chose to follow lc in its decision, there has been an overall increase in the use of untraced series statements across all types of record-encoding volumes are added to the collection under the title of the set. the june 2006 decision by lc to produce individual volume records when a distinctive title exists caused concern about the integrity of the libraries’ existing open volume set records. because such records typically have enumeration indicated in the subfield n, and sometimes p, of the 245 field, the program searches for instances of those subfields. in addition, the program detects the presence of numerals in the 245 and keywords such as figure 1. an example report from catcq 44 information technology and libraries | march 2009 levels. to address this issue, catqc searches all wcp records for 490 fields with first indicator 0. catalogers check the authority files for the series and make any necessary changes to the records. this is by far the most frequent correction made by catalogers. links (8) to provide users with information about the nature of the urls displayed in the catalog, catalogers insure that explanatory text is recorded in subfield 3 of the 856 field. catqc looks for the absence of subfield 3, and, if absent, displays the 856 field in the report as a hyperlink. the cataloger adds the appropriate text (e.g., full text) as needed. subject headings with second indicators 4, 5, 6, and 7 (9) the catqc report reviewed by catalogers includes subject headings with second indicator 4. when these headings duplicate headings already on the record, catalogers delete them from our local system. when the headings are not duplicates, the catalogers change the second indicator 4 to 0. typically, 6xx fields with second indicators 5, 6, and 7 contain non-english headings based on foreign thesauri. these headings can conflict with lc headings and, in some cases, are cross references on lc authorities. the resulting split files are not only confusing to patrons, but also add to the numbers of errors reported that require authority maintenance. for these reasons, our policy is to delete the headings from our local system. catqc detects the presence of second indicators 5, 6, or 7 and creates a modified file with the headings removed with one exception: a heading with second indicator 7 and subfield 2 of “nasat,” which indicates the heading is taken from the national aeronautics and space administration thesaurus, is not removed because the local preference is to retain the “nasat” headings. n library-specific issues catqc resolves local problems when needed. for example, when more than one lc call number was present on the record, the wcp spine manifest sent to the vendor used to contain the second call number, which was affixed to the item. when the wcp records were loaded into the library’s catalog, the first call number populated the holding. as a result, there was a discrepancy between the spine label on the book and the call number in the catalog. prior to generating the report, catqc found multiple instances of call numbers in the records in the wcp file and created a modified file with the call numbers reordered so that the correct call number was used on the holding when the record was loaded. previously, the library’s opac did not display the text in subfield 3 of the 856 field, which specifies the type of material covered by the link, and to the user it appeared that the link was to a full-text resource. this was particularly troublesome for records with lc links to table of contents, publisher descriptions, contributor information, and sample text. to prevent user frustration, catqc was programmed to move the links on the wcp records to 5xx fields. when the opac interface improved and the programming was no longer necessary, catqc was revised. n analysis to see how well catqc and oclc’s bibliographic notification service were meeting our goal of maintaining high-quality bibliographic control, 63 reports were randomly selected from the 171 reports generated by catqc between october 2007 and april 2008. catqc found no problems in twelve (19 percent) of the selected reports. these twelve were not used in the analysis, leaving fifty-one catqc reports examined with at least one potential problem flagged for review. an average of 35.6 percent of the records in the sample of reports was flagged as requiring review by a cataloger. an average of thirteen possible problems was detected per report. of these, 55 percent were potential problems requiring at least some attention from the cataloger. the action required of the cataloger varied from simply checking the text of a field displayed in the report (e.g., 246 fields) to bringing up the record in aleph and editing the bibliographic record (e.g., verifying and correcting series headings or eliminating unwanted subject headings). why the relatively high rate of false positives (45 percent)? to minimize missing serials and volumes belonging to sets, catqc is designed to err on the side of caution. two of the criteria listed earlier were responsible for the vast majority of the false positives generated by catqc: 245 fields with subfields a or b that contain numerals and 245 fields with subfields a or b that contain red-flag keywords. clearly, if every record with a numeral in the 245 is flagged, a lot of hits will be generated that are not actual problems. the list of keywords was purposefully designed to be extensive. for example, “volume,” “vol.,” and “v.” are all triggers causing a record to be flagged. therefore a bibliographic record containing the phrase “volume cost profit analysis” in the 245 field would be flagged as a potential problem. at first glance, a report filled with so many false positives may seem inefficient and burdensome for catalogers to use; however, this is largely mitigated by the excellent display format. the programmer worked closely with catcq and shelf-ready material | jay, simpson, and smith 45 the copy cataloging unit staff to develop a user-friendly report format. each record is framed separately, making it easy to distinguish from adjoining records. potential problems are highlighted with red lettering immediately alerting catalogers to what the potential problem might be. whenever a potential problem is found, the text of the entire field appears in the report so that catalogers can see quickly whether the field triggering the flag is an actual problem. it takes a matter of seconds to glance through the 245 fields of half a dozen records to see if the numeral or keyword detected is a problem. the catalogers who work with these reports estimated that it took them between two and three hours per month to both review the files and make corrections to bibliographic records. a second component of bibliographic quality maintenance is oclc’s bibliographic record notification service. this service compares newly upgraded oclc records with records held by the library and delivers the upgraded records to the library. because catqc flags records with encoding levels of 2, 3, 5, 7, e, j, k, and m, it was possible to determine if these records had, in fact, been upgraded in oclc. in the sample, thirty-three records were flagged because of the encoding level. no upgrade had been made to 21.2 percent of the records in oclc as of august 2008. upgrades had been made to 45.5 percent of the records. the remaining 33.3 percent of the records were manually loaded by catalogers in copy cataloging. these typically are records for items brought to copy cataloging by acquisitions and licensing because they meet one or more of the criteria for individual inspection discussed previously. when catalogers search oclc and find that the received record has not been upgraded, they search for another matching record. a third of the time, a record of higher quality than that received is found in oclc and exported to the catalog. the reason why the record of better quality is not harvested initially is not clear. it is possible that at the time the records were harvested both records were of equivalent quality and by chance one was enhanced over another. in no instance had any of the records originally harvested been upgraded (this is not reflected in the 21.2 percent of records not upgraded). encoding level 8 records are excluded from catqc reports. because of the relatively quick turnaround for upgrades of this type of copy, the library decided to rely solely on the bibliographic record notification service. n technical specifications catqc is a console application for windows. written in standard c, it is designed to be portable to multiple operating systems with little modification. no graphic interface was developed because (a) the users are satisfied with the current operating procedure and (b) the treatment of the records is predefined as a matter of local policy. the user opens a command console (cmd.exe) and types “catqc”+space+“[name of marc file]”+enter. the corrected file is generated; catqc analyzes the modified file and creates the xml report. it moves the report to a reviewing folder on a file server across the lan and indicates to the user that it is terminating. modifications require action by a programmer; the user cannot choose from a list of options. benefits include a 100 kb file size and a processing speed of approximately 1,000 records per second. no quantitative analysis has yet been done related to the speed of processing, but to the user the entire process seems nearly instantaneous. the genesis of the project was an interest in the record structure of marc files brought about in the programmer by the use of earlier local automation tools. the project was speculative. the first experiment contained the programming structure that would become catqc. one record is read into memory at a time, and there is another array held for individual marc fields. conceptually, the records are divided into three portions—leader, directory, and dataset—when the need arises to build an edited record. initially there was no editing, only the production of the report. the generation of strict, valid xml is a significant aspect of catqc. an original document type was created, along with a corresponding cascading style sheet. the reports are viewable to anyone with an xml–capable browser either through file server, web server, or e-mail. (the current version of internet explorer does not fully support the style sheet syntax.) this continues to be convenient for the report reviewers because they do not have to be client application operators. see appendix a for an excerpt of a document instance and appendix b for the document type definition. catqc is not currently a generalized tool such as marcedit, a widely used marc editing utility that provides a standard array of basic capabilities: field counting, field and subfield deletion (with certain conditional checks), field and subfield additions, field swapping and text replacement, and file conversion to and from various formats such as marcxml and dublin core as well as between marc-8 and utf-8 encodings.6 marcedit continues to grow and does offer programmability that relies on the windows scripting host. this requires the user to either learn vbscript or use the wizards offered by marcedit. the catqc development goal was to create a report, viewable through a lan or the internet, which alerts a group of catalogers to potential problems with specific records, often illustrating those problems. although it might have been possible to use a combination of marcedit capabilities and local programming to help achieve this goal, it likely would have been a more cumbersome route, particularly taking into consideration the multidimensional 46 information technology and libraries | march 2009 conditionals desired. it was deemed easier to write a program that addresses local needs directly in a language already familiar to the programmer. as catqc evolved, it was modified to identify more potential problems and to do more logical comparisons as well as to edit the files as necessary before generating the reports. catqc addresses a particular workflow directly and provides one solution. it is procedural as opposed to event driven or object oriented. with version 1.3, the generic functions were extracted into a marclib 1.0, a common object file format library. functions specific to local workflow remain in catqc. the program is freely available to interested libraries by contacting the authors. as of this writing, the university of florida plans to distribute this utility under the gnu public license version 3 (see www.opensource.org/licenses/gpl-3.0.html) while retaining copyright. n conclusion catqc provides catalogers an easy way to check the bibliographic quality of shelf-ready material without the book in hand. as a result, throughput time from receipt to shelf is reduced, and staff can focus data review on problem areas—those affecting access or interfering with local processes. some of the issues addressed by catqc are of concern to all libraries while others reflect local preferences. the program could be easily modified to conform to those preferences. automation tools such as catqc are of key importance to libraries seeking ways to streamline workflows to the benefit of users. references and notes 1.

smith, anastasia guimaraes, mandy havert, and tatiana h. prokrym missing items: automating the replacement workflow process academic libraries handle missing items in a variety of ways. the hesburgh libraries of the university of notre dame recently revamped their system for replacing or withdrawing missing items. this article describes the new process that uses a customized database to facilitate efficient and effective communication, tracking, and selector decision making for large numbers of missing items. t hough missing books are a ubiquitous problem affecting multiple aspects of library services and workflows, policies and procedures for handling them have not generated a great deal of buzz in library literature. for the purpose of this article, missing books (and other collection items), refers to items that were not returned from circulation or have otherwise gone missing from the collection and cannot be located. significant staff time may be invested in the missing-book process by departments such as collection development, circulation, acquisitions, database management, systems, and public services. more importantly, user experiences can be negatively affected when missing books are not handled efficiently and effectively. while most libraries have procedures for replacing or suppressing catalog records for items that are missing from the stacks or have been checked out and never returned, few have made these procedures public. this article describes the procedure developed by the hesburgh libraries of the university of notre dame to replace missing items or to withdraw them from the catalog. hesburgh libraries’ procedure offers streamlined, paperless routing of records for missing materials, accounts for “nondecisions” by subject librarians, and results in a shortened turnaround time for acquisitions and catalogmaintenance workflows. hesburgh libraries’ experience in 2005, hesburgh libraries recognized its need to develop a streamlined method of processing missing items. because of personnel changes and competing demands on staff time, the routine handling of missing materials had been suspended for roughly five years. during this period, circulation staff continued to perform searches. when staff declared an item officially missing, the item’s catalog record was updated to the item process status “missing” (mi) and paper records were routed to the collection development department office, but no further action was taken. the mounting backlog of missing items in the catalog became a recurring source of frustration to patrons and public-services employees alike. searches for books that were popular among undergraduates often led to items with a “missing” status. to compound the problem, budgetary constraints resulted in the suspension of spending from the fund earmarked for the replacement of missing items. subject librarians were forced to use their own discipline-specific funds to replace items in their areas, but because there was no systematic means of notifying subject librarians of missing items, they replaced items very rarely and on a case-by-case basis—primarily when faculty or graduate students asked a selector to purchase a replacement for an item critical to their teaching or research. also in 2005, a library-wide fund to replace materials was made available. unfortunately, by that time, the tremendous backlog of catalog records for missing items rendered the existing paper-based system unworkable. as a result, a small task force was formed to manage the backlog and to develop a new method for handling future missing items. hesburgh libraries’ solution the missing items task force was initially composed of eight members representing all departments affected by changes in the procedures for handling missing books. the task force was chaired by the subject librarian for psychology and education. other members represented the circulation, collection development, cataloging, catalog and database maintenance (cadm), monograph acquisitions, and systems departments. during the initial meeting, each member described their portion of the workflow and communicated their requirements for effectively completing their parts of the process. because most items with the status “missing” were ones that a patron or patrons had either recently used or requested and could therefore be considered relatively high-use material, the task force quickly determined that the search time for missing books should be shortened from one year to six months. task force members from monograph acquisitions were particularly interested in making this change because newer books are more easily replaced if requests were made cheri smith (cheryl.s.smith.454@nd.edu) is coordinator for instructional services, anastasia guimaraes (aguimara @nd.edu) is supervisor of catalog and database maintenance, mandy havert (mhavert@nd.edu) is head of the monograph acquisitions department, and tatiana h. prokrym (tprokrym@ nd.edu) is senior technical consultant at hesburgh libraries of the university of notre dame, notre dame, indiana. 94 information technology and libraries | june 2009 sooner—many books, especially in the sciences, go out of print quickly and become difficult to replace. the systems task force member supplied a spreadsheet containing the roughly three thousand missing items. this initial spreadsheet included all fields that might be useful for staff in monograph acquisitions, cataloging, cadm, and collection development. various strategies for disseminating the spreadsheet to subject librarians were discussed, but all ideas for how the subject librarians might interact with the spreadsheet seemed laborious and inevitably required that someone sort through each item on the list to determine whether the records needed to be sent to monograph acquisitions or cadm for further processing. the process seemed feasible for a onetime effort, but the task force did not see it as a suitable permanent solution. the task force then considered the feasibility of developing a customized database to manage all of the information necessary for library employees—primarily subject librarians and monograph acquisitions and cadm staff—to participate in the processing of missing books. the database once the task force determined that a database would serve hesburgh libraries’ needs more efficiently than a spreadsheetor paper-based system, the task force enlisted the help of an applications developer. hesburgh libraries had previously created a database for handling journal cancellations, and the task force decided to base the replacement application upon this model. the application is therefore written in php and uses a mysql database. the first step in designing the database was to determine which bibliographic metadata (such as call number, isbn, issn, imprint, etc.) would be required by subject librarians to specify replacement or withdrawal decisions, including whether the item was to be replaced with the same edition, any edition, or the newest available edition. because replacement funds may not always be available, the task force wanted to enable the selector to identify other funds to use for the replacement purchase. finally, the task force felt that, no matter how easy the system was to use, there would always be a few subject librarians who choose not to use it. it was therefore important that the database could also account for “nondecisions” from subject librarians. other general database requirements included that it be available through any web browser and accessible to only those people who are part of the replacement-book process. with those requirements in mind, the task force created a list of metadata elements to be included in the database (see table 1). on a quarterly basis, the application pulls the database fields—title, author, call number, sub library, imprint, isbn or issn, barcode, previous fund, local cost, description, item status, update date, bib system number, and system number—from hesburgh libraries’ ils (aleph v18) and imports into the replacements database. for each item, bibliographic, circulation, and acquisitions information is retrieved from aleph and combined to generate the export data file. procedurally, a list of all items with an item process status of “missing” is first retrieved into a temporary table from the item record (z30) table. this temporary table consists of the system number, status field, sublibrary, collection, barcode, description, and the last date the item was modified (z30-update-date in aleph). a second temporary table is then created that includes the purchase price and fund code originally used to purchase the item. the two temporary tables are joined and their information merged, creating a single list of missing items and related acquisitions information. this list is then linked to the bibliographic tables to obtain key bibliographic information such as title, author, imprint, isbn or issn, the ils bibliographic number, and the barcode. these combined results are converted into an ascii text file for import into the mysql replacements database. upon the import of the ascii file, an e-mail is sent to the collection development e-mail list, informing subject librarians that data has been loaded and is ready for their review and input. table 2 lists the purpose of each of the nine tables within the replacements database. figure 1 illustrates the relationships and linking fields table 1. fields for the replacements database database field data type title varchar(200) author varchar(150) call number varchar(30) sub library

for subject librarians. the first pick list is the action to take field. primary choices are “any edition,” “newest edition only,” “micro format only,” and “do not replace.” the second pick list is the new fund field. the default choice for this field is hesburgh libraries’ replacement fund code, although any acquisitions funds may be selected. both pick lists provide data integrity and assurance that all input from the subject librarians is standardized. two internal fields, record id and transfer date facilitate programming and identification. these fields are very important for auditing and tracking replacement records through the replacement process. rollbacks are easily handled through the manipulation of these two fields. programmatic process for the initial implementation of this application, the task force decided that batch loads would be preformed on an as-needed basis. after the initial phase of the project, the task force implemented a quarter-based schedule. for each data load, the exported records are written to a text file, which is then imported into the replacements database through an import script. the import script archives the previous group of processed records, appending them to a set of historical tables stored within the database. the import script further processes the aleph data by eliminating duplicate records and ensuring there is only one record per barcode and system number. the historical tables are checked to see if a missing item has already been loaded into the database and processed. if a record has already been processed, it is automatically deleted from the newly imported item list. after the successful completion of the data load, an e-mail is automatically generated notifying subject librarians that the replacements database is ready for their review and input. the verified missing item records are then transferred to the main database table, “tblreplacements,” and are ready for updating. included in the e-mail to subject librarians is a link that directs them to a search window allowing them to take action on the missing items (see figure 2). once the subject librarians update the records, the application provides a mechanism to distribute missing book records to the appropriate departments for further processing. a collection development staff member runs a series of reports, each one creating a microsoft excel spreadsheet. the first report lists missing-book records marked for replacement and is sent to monograph acquisitions for processing. missing books that have been marked “do not replace” or have had no action taken on them after a certain time period are exported to a separate excel spreadsheet that is sent to cadm for suppression or removal of cataloging records. for each report that is run, the application generates an e-mail message, notifying all necessary departments that there is information to be processed. a list of processed records is available for viewing and distribution to cadm and acquisitions as illustrated in figure 3. the application also provides customized manipulation of the data records that are exported to each of the departments. this customization pulls together only the specific fields of interest to each department such that each export template is unique to each department’s needs. at the end of each replacement cycle, the application automatically creates backups and archives the missing book records. table 2. tables and their purposes within the database table description alephdump stores imported aleph data before

job is surprisingly simple. after entering their network id and password to gain access to the database, they can select how they wish to view the list of missing books—by selected call number ranges, by the budget code with which the books were originally purchased, or by system number (the last two options are rarely used). subject librarians can also view items that have already been processed, and they are able to sort this list by subject librarian, action taken, new budget code, or call number. figure 1. relationship diagram for the nine database tables that were created for this application. the aleph system number is used as the primary linking field for most of the tables. missing items: automating the replacement workflow process | smith et al. 97 initially, subject librarians encounter a list of brief records for each item in the database. the brief records include system numbers, titles, authors, volume numbers (if applicable), call numbers, sublibraries, and isbns or issns. if a record has already been reviewed by a subject librarian, the list will include actions taken and the names of the subject librarians who took the action. to take action on an item, subject librarians select the system number, displaying the full record (see figure 4), and may then choose to replace the book with the same edition, any edition, the newest edition available, or a microform version. by using a drop-down menu, the selector can elect to pay for the replacement with replacement funds or with their own subject funds. subject librarians who choose to replace books with their own funds are rewarded at the end of the quarter when their replacement requests appear at the top of the queue for processing by monograph acquisitions. additional functionality includes the ability to directly link to and browse opac records for items in the database. replacement funds cannot be used for second copies of books, so quick access to opac records is often useful. it also facilitates determining if the library owns other editions of the item before taking action. a notes field allows subject librarians to communicate special instructions for monograph acquisitions or cadm, and records can be e-mailed to other librarians for additional input with just a few clicks. subject librarians are able to return to the database at any time during a given quarter to continue making decisions on their missing books and make any adjustments to prior decisions as necessary. if a subject librarian takes no action on an item by the end of the quarter, it is assumed that it is not to be replaced, and these untouched items are sent to cadm for removal or suppression. figure 2. replacements application search window figure 3. processed book records ready to be sent to monograph acquisitions and cadm. notification and data transmission to these units are achieved through the send buttons on this webpage. 98 information technology and libraries | june 2009 monograph acquisitions workflow once the quarterly database processing completes, a comma-separated file is delivered to the shared monograph acquisitions e-mail address. monograph acquisitions staff format, sort, and begin searching the spreadsheet, giving priority to the orders designated for replacement by subject librarian funds over those funded from the library replacement fund. staff members routinely search the library catalog for duplicate titles or review orders in process for the same title prior to searching with our library materials vendors. staff members ensure that replacement funds are not used to purchase second copies. material that is not available for purchase is referred by monograph acquisitions to the subject librarian for direction. sometimes the materials may be kept on order with a vendor to continue searching for outof-print or aftermarket availability. other times it is necessary for staff to cancel the order and remove the record from the system completely. likewise, the missing edition may have been subsumed by a newer, revised edition. subject librarians are contacted by search and order staff in the monograph acquisitions department regarding availability of different editions when they did not specify that any edition would be acceptable. when the monograph acquisitions department places a replacement-copy order, the search-and-order unit adds an ils library note field code designating the item is a replacement (rplc), the bibliographic system number of the item being replaced, and any typical order notes such as the initials of the staff member placing the order. the rplc code alerts the receipt unit to route new items to the cataloging supervisor, who then reviews and directs the items to either cataloging or cadm for processing. catalog and database maintenance (cadm) workflow cadm is usually the last unit to edit records in the missing books workflow. the unit receives two reports from the database: a “do not replace” list and a “no action taken” list. both reports get the same treatment: all catalog records for titles listed are removed from the catalog. removal of catalog records is accomplished either by suppression/ deletion of the bibliographic records or complete deletion of all records (item, holdings, bibliographic, and administrative) from the server. for titles that have order or subscription records attached to bibliographic records, a suppression/deletion procedure allows the record to be suppressed from patrons’ view while preserving the title’s order and payment history for internal staff use. records are completely deleted when no such information exists (e.g., a gift copy or an older record that has no such data attached). because it takes a long time to review each newly loaded batch from the catalog into the database, some records that come to cadm for deletion no longer need to be deleted if missing books are found and returned to the shelves. it is very important for staff working on the cleanup of records to check the item process status and not delete any items that have been cleared of the “missing” status. fortunately, aleph allows staff to look up an item’s history and view prior changes made to the record. this item history feature eliminates unnecessary shelf checks for items appearing on cadm reports that are no longer listed as “missing” in the catalog. occasionally, cadm receives requests to delete records directly from monograph acquisitions and cataloging staff because of a revised selector decision. this often occurs when a replacement item is only available in a different edition from figure 4. full record for a missing book in the replacement database missing items: automating the replacement workflow process | smith et al. 99 the one originally sought, or when an item is ultimately unable to be replaced because it has gone out of print or a vendor backs out of a purchase agreement. when a different edition is received to replace a missing item, the replacement copy is sent by the receipt unit in monograph acquisitions to cataloging for copy or original cataloging, and cadm is alerted by either monograph acquisitions or cataloging staff if the record for the missing item needs to be deleted. because monograph acquisitions often orders the replacement on its own record with appropriate bibliographic information (we keep the original record just in case the missing piece is found while we wait for replacement), the record for the missing book does not come to cadm on either of the two reports. perhaps in a library with a different makeup of technical services the process would be more streamlined, but because hesburgh libraries has separate cataloging and database maintenance units, we have created such partnerships to make sure nothing falls through the cracks. so far it has worked well, and every party in the process knows and carries out their responsibilities. issues while the initial implementation successfully brought a large backlog of missing records into the database, subsequent loads included duplicate records of some items processed in earlier batches. this duplication occurred, for example, if an item was identified for replacement in a prior database review cycle, but a replacement request had not yet been processed by monograph acquisitions staff. because such an item is still identified as “missing” in the catalog, it was again included in data loaded from the catalog into the missing-books database, creating confusion for selectors, cadm, and monograph acquisitions. to resolve this problem, the import process was revised to include a search for previously loaded items, deleting them before records are viewed by collection managers. a second issue involved the timing of the data load from the catalog into the replacements database. for various reasons, the data load file was not fully generated for several of the scheduled processing dates. to remedy this problem, the application automatically generates an e-mail confirming a successful data load to the collection development department staff. there is continued debate as to whether the missingitems file should be created on a daily basis, providing the capability for collection development to import new data at one time rather than periodically. results since implementing our new system, hesburgh libraries has processed records for 5,141 missing items. since its creation, twenty-five librarians have consulted the database and twenty-three of thirty subject librarians have used the database to request replacements. of the 5,141 records loaded into the database, 2,537 items (49 percent) have been selected for replacement, and 2,604 items (51 percent) have either been suppressed or deleted from our catalog. replacement funds are renewed on an annual basis and have not yet run out. as a reflection of the collection strengths at hesburgh libraries, most of the missing books (21 percent) fell in the theology/religion call number range. language and literatures was the second most popular collection for missing items (17 percent). other collections with significant numbers of missing books are history (15 percent), social sciences (17 percent), science (12 percent), and philosophy (10 percent). conclusion although the process could certainly be further developed and refined, the hesburgh libraries missing books application is an amazing improvement over the extremely outdated paper-based method of dealing with missing library materials. the process works; it is both efficient and effective, and employees who engage in the process have reported satisfaction with it. it has not only allowed hesburgh libraries to catch up on its backlog but, more importantly, to stay current and organized, keeping the catalog more accurate and patrons more satisfied. furthermore, should the libraries opt to do a full inventory in the future, the current system will prove invaluable. the authors are pleased to have the opportunity to share our experiences with interested libraries. feel free to contact any of the authors for further

(rachel.wittmann@utah.edu) is the digital curation librarian, university of utah. © 2022. abstract the relationship between physical and digitized rare books can be complex and, at times, nebulous. when building a digital library, should showcasing a representative slice of the physical collection be the goal? should stakeholders focus on preservation, high-use items, or other concerns? to explore these conundrums, a special collections librarian and a digital services librarian performed a comparative analysis of their library’s physical and digital rare books collections. after exporting marc metadata for the rare books from their ils, the librarians examined the place of publication, publication date, and broad subject range of the collection. they used this data to create a variety of visualizations with the open-source digital humanities tool tableau public. next, the authors downloaded the rare books metadata from the digital library and created illuminating data visualizations. were the geographic, temporal, and subject scopes of the digital library similar to those of the physical rare books collection? if not, what accounted for the differences? the implications of these and other findings will be explored. introduction as of august 2019, the special collections division of the university of utah j. willard marriott library held over 256,000 printed works and archival collections. approximately 22% of the collection, or just over 55,000 works, belongs to the rare books department (https://lib.utah.edu/collections/rarebooks/), which contains not only books but serials, maps, manuscripts, ephemera, and other formats. the collection covers over 4,000 years of human history, with its earliest piece, a cuneiform tablet, dating to the mid-twenty-third century bce; contains works from nearly 100 different countries; and represents a wide variety of topics, including the exploration and settlement of the american west and the history of the book. the rare books department, a subset of special collections, specifically seeks to document the history of written human communication and actively collects historical items to enhance teaching and research at the university of utah. the marriott library has been adding digitized works from the rare books department to its digital library (https://collections.lib.utah.edu/) for over 25 years. approximately 780 works, or 1.42% of the rare books collection, has been digitized to date. however, no formal collection development plan was ever written, and rare books were selected for digitization by both curators and patrons. unfortunately, the reason a particular item was digitized is not recorded in the system: it is unclear if age, research value, physical condition, a desire to bring forward underrepresented stories, or a combination of these and other factors influenced the decision to digitize a rare book. this piecemeal approach to digital library collection development, while not uncommon, made it difficult for library staff and patrons to determine the relationship between the digital and physical collections of rare books. it also presented challenges when library staff mailto:allie.mccormack@utah.edu mailto:rachel.wittmann@utah.edu https://lib.utah.edu/collections/rarebooks/ https://collections.lib.utah.edu/ information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 2 attempted to communicate the scope and intent of the digital library to patrons, who assumed that the digitized items were representative of the overall collection. given their expertise in library metadata, the authors decided to analyze both traditional library catalog records and digital library records for the rare books collection and explore whether the digital collection was proportionally representative of the physical collection or if it differed in geographic, temporal, or subject scope in a meaningful way. they then created a series of data visualizations to better communicate information about the library’s rare books holdings. literature review while much has been written about methods and criteria for selecting special collections items to be digitized and the effects of digitization on collection accessibility, few authors have discussed the relationships between digital collections and the physical collections from which they were sourced. in their highly detailed treatise on selection strategies for digitization, ooghe and moreels identify representativity, a method that “aims for a final selection that provides a representative view of the original collections,” as one of 25 selection criteria for digitization projects.1 however, alexandra mills notes that “without a thorough understanding of the institution and collections, it is impossible to create truly representative collections.”2 because many digitization initiatives are undertaken in response to user requests, preservation concerns, or the availability of projectbased funding, it is likely that most libraries do not plan for their digital collections to be representative of their overall special collections holdings. as peter michel states, the digital collections at the university of nevada, las vegas, were explicitly built with popular history and popular culture in mind and were never intended to be “surrogates of the collection.”3 bradley daigle of the university of virginia explained that digitization could be undertaken to alleviate preservation concerns, respond to defined research needs, or to brand certain online content, but this approach could give the mistaken impression “that only the important materials are digitized.”4 despite the gaps in the literature, having an explicit collection development policy is still considered paramount; indeed, it is the very first principle listed in the national information standards organization (niso)’s framework for building “good” digital collections.5 to investigate this type of documentation further, a google search was employed using the search term “digital collection development policy site:edu”. this yielded 10 publicly accessible digital collection development policies from academic libraries in the united states: 6 • amherst college library (https://www.amherst.edu/library/services/digital/digitalcolldev) • emerson college archives and special collections (https://www.emerson.edu/policies/digital-collections-development-policy) • colorado state university libraries

mccormack and wittmann 3 • oregon health and sciences university digital collections (https://www.ohsu.edu/library/ohsu-digital-collections-development-policy) • university of north texas university libraries (https://library.unt.edu/policies/collection-development-digital-collections/) • wesleyan university digital library (https://digitalcollections.wesleyan.edu/about/whatwe-collect) • williams college special collections (https://specialcollections.williams.edu/collectiondevelopment-policies/digital-collections/) in reviewing the sample of 10 universities’ digital collection development policies, homogenous content becomes apparent. almost all of the policies include a mission statement, scope, and selection criteria for potential digital collection items. all policies include criteria that physical materials should meet in order to qualify for digitization. the most common criteria for digitization are materials that are rare or unique, high-use, fragile, important to institutional or regional history, and/or support campus curriculum or faculty research. in addition, the clearance to publish materials online is ubiquitous among the policies. materials eligible for online display must either be in the public domain or intellectual property rights are held by the institution, and materials currently under copyright must receive permission from the copyright holder. a measured approach to digitization qualification has been employed by the university of north texas (unt) libraries’ digital collections and the northern illinois university digital library (niudl). unt libraries’ digital collections policy lists levels of criteria that materials must meet in order to be digitized and included in the digital library; to qualify for digitization, all criteria on level one must be met while only one criterion from level two is needed. niudl includes a priority factor rubric which includes criteria categories and corresponding numerical scale with a maximum point of 35, the higher value signifying an elevated priority. six of the 10 policies include prioritizing materials that support diversity and inclusion missions on campus. amherst college has leveraged their digital collection development policy to include content that would increase perspectives of underrepresented groups within the digital collections and traditionally underrepresented groups more broadly. niudl includes marginalized groups as a collection priority area in order to “deepen public understanding of the histories of people of color and other communities and populations whose work, experiences, and perspectives have been insufficiently recognized or unattended” and lists over 20 such groups. the collection candidate’s relationship to other collections is outlined in four of the 10 policies. georgetown university requires that “the materials form a coherent collection, fill gaps in existing collections, or complement existing collection strengths.” amherst college evaluates whether digitization would “enhance public awareness of archives’ collection strengths.” another function of a digital collection development policy is to inform the public on the scope and provenance of contents in their digital library. the unt digital collection policy includes a section outlining the content contributors, including partners, which can be beneficial for large-scale digital libraries that host collections from multiple partners. unt is also exemplary in defining collection curators and their responsibilities while underscoring the nature of this role, likely changing over time and not set to an individual. with no written digital collection development policy regarding special collections at the marriott library, the authors would first have to analyze both the physical and digital special collections before determining what factors may have influenced the digitization of these materials. libraries are gathering massive amounts of data, ranging from the metadata of their varied collections to patron usage statistics of both physical and digital collections. interpretation of the

technology and libraries june 2022 rarely analyzed | mccormack and wittmann 4 ever-growing accumulation of data can quickly become complex. by visualizing data, we are able to interpret large and often messy sets of data while processing multiple aspects of the data concurrently. for example, the ohio state university (osu) libraries used tableau desktop to combine data from various departments in order to better manage and explore information.7 tableau was osu’s data visualization software of choice due to its ease of use and accessibility, and the program was also used to create dashboards that blend data from various sources for realtime visualizations. bibliographic metadata cleanup to understand the marriott library’s collections, one must first understand the relevant metadata, which for the rare books department is in the machine-readable cataloging (marc) format. a popular criticism of marc, commonly used in traditional library cataloging, is that the schema is highly regulated and, at times, redundant. however, for the purposes of this project, those qualities proved to be a boon. an older, uncorrected record in the digital library might list london as the place of publication for a particular book, but it was not immediately apparent if that referred to london, england; london, ontario; or london, ohio. however, a marc record would not only list a book’s city of publication in the 260 or 264 field but would also contain a two or three-letter code in the 008 field that specified the country, us state, canadian province or territory, or australian state or territory in which it was published. for this reason, the authors decided to base their analysis on marc record data from the physical collection instead of the dublin core metadata used in the digital library. in order to tease out the relationships between our digital and physical collections, each of the approximately 55,000 rare books bibliographic records stored in alma, the marriott library’s cloud-based library services platform, would have to have a common set of data points that could be compared. for the purposes of this analysis, the authors chose to investigate the place of publication and the subject of each work. despite the relative rigidity of marc metadata, some of the alma records lacked country of publication data in the 008 field. these records were not incorrect, but merely outdated: some had been copied directly from paper catalog card s when the library first transitioned to a computer-based cataloging system, while others were created using different metadata standards. approximately 6,000 rare books either completely lacked a country code in the 008 field or had data that could possibly be enhanced by, for example, replacing a code for the united states with a code for a particular state. instead of editing all 6,000 records by hand, the cataloger wrote several metadata normalization rules in alma to automatically correct the most obvious errors. records that listed chicago as the place of publication were assigned the marc geographic code for illinois, while those that were published in lugduni batavorum, the latin designation for leiden, were given the geographic code for the netherlands. however, 3,000 records were unable to be enhanced in this manner, either because their place of publication was an ambiguous city name like cambridge or because the place of publication was listed as unknown. the cataloger examined each record individ ually and was ultimately unable to assign a marc geographic code to 1,682 records, most of which were arabic manuscripts or advertising pamphlets that simply did not list a place of publication or creation. while these records would be excluded from the place of publication analysis, they could be mined for data on other topics. with the marc records as complete as possible, the metadata was exported from alma into an excel spreadsheet and given to the metadata librarian for further manipulation. information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 5 metadata transformation & visualization creation the next phase involved standardizing the raw metadata to create human readable data, rather than marc codes, that are necessary to produce data visualizations. once the physical rare books ’ bibliographic metadata was updated in alma, it was then exported as a comma-separated values file. the raw data export produced a massive spreadsheet containing over 50,000 marc records. these records included twoand three-letter location codes for the place of publication from the library of congress marc code list for geographic areas. two-letter codes are used for most countries, while three-letter codes are used for states within the united states, provinces within canada, and territories within the united kingdom. while this additional level of location data was available for books from the united kingdom and canada, it was decided to review the collection at a country level for consistency and map display. books from the united states, however, were analyzed on a state level, considering the research is germane to an american institution. using a list correlating these codes to the location name provided by the library of congress (https://www.loc.gov/marc/countries/countries_code.html), a vlookup formula was used in microsoft excel to add the location names to the marc records. the vlookup formula pulls in data from one table to another as long as the two tables have one data field in common. in this exercise, both tables of data contained the library of congress location codes, therefore the lc location codes were used to add the location names to the table containing the marc metadata. once the location names were added, there were some additional quality control steps required, as lc location names that included outdated country names posed issues to mapping the data to current country names and boundaries. for example, we combined the codes for east germany and west berlin for the one representing contemporary germany. for countries that have since been dissolved and rezoned to multiple countries, e.g., the ussr and czechoslovakia, these records were manually checked for city names and then added to the current country. once this process was completed, the results showed the rare books were published in 97 countries and all 50 united states, as well as the district of columbia. examining the subject content of the rare books physical collection was another aspect of analysis for this project. in contemplating this analysis, using the lc subject heading field was considered, however, faceting of lc subject headings and the structure of the exported data posed too many issues for a rather simple analysis. instead, the library of congress call number was used to extract high-level lc classification information for each work by separating the first two letters of the call numbers included in the exported marc metadata, which indicated lc class and subclass. to add the lc class and subclass names to these letters, a vlookup formula was used again to match the letter codes to the list of lc classification categories. once classification categor ies were added to the 55,000 records, works from all 21 lc master classes and 190 subclasses were represented in the rare books collection. in addition to the physical rare books collection held at the marriott library, there is a selection of this collection that has been digitized and is accessible in the marriott digital library. the rare books digital collection (https://collections.lib.utah.edu/search?facet_setname_s=uum_rbc) comprises 780 works, although this number includes unique records for individual volumes within a series and therefore is not a true comparison to marc metadata records, which contain one record for a series. for example, the silver reef miner, a newspaper “devoted to the mining interests of southern utah” published during the late nineteenth century, has 30 individual volumes in the digital library, but these are represented in just one marc record. in order to compare the digital collection to the physical collection, the datasets would need to have https://www.loc.gov/marc/countries/countries_code.html https://collections.lib.utah.edu/search?facet_setname_s=uum_rbc information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 6 consistent data for comparison, namely place of publication and lc classification derived from call numbers. the digital collection metadata is in the dublin core schema, which does not include all of the metadata found in the marc metadata, nor does it use the same format. while there is a dublin core spatial element used to capture geographic data on what the item is about, this does not always align neatly with the location of an item’s publication. for example, reise in das innere nord-america in den jahren 1832 bis 1834 (2 volumes) is a book printed in germany that documents an expedition to north america in 1832–1834 and includes illustrations of native american people from the swiss artist karl bodmer. for these volumes, the appropriate dublin core spatial data would include the specific regions the expedition traveled to in north america; in the marc 26x field, however, it contains koblenz, germany, the city where the volumes were published. call number data was included for many digitized works, but not in a consistent format. in order to use the same data to compare the physical rare books collection to the digital one, the digital collection metadata was updated with the improved/accurate call numbers found in the marc metadata. another improvement to the digital collection metadata was the addition of the metadata management system (mms) id unique numerical identifiers that aid in locating a record in the alma system. when the rare books’ descriptive metadata was originally converted to dublin core during the digitization process, some titles and call numbers were changed and became different from their physical counterparts. the inclusion of the mms id allows for a consistent identifier between the physical and digital collections. when selecting data visualization software, being able to create a map of the places where books in the rare collection were published was a priority. considering the goal of creating an easily replicable workflow for other libraries, the authors sought a freely accessible program that did not require advanced geospatial skills, unlike esri’s arcgis software. tableau software is a data visualization software package with both a public and desktop version. the tableau desktop version requires a subscription fee while tableau public is open access. for the purposes of this study, tableau public offered open access and mapping features that are enabled without any geospatial knowledge necessary. analysis creating a variety of data visualizations allowed information about the rare books physical and digital collections to be more apparent than merely browsing entries in a spreadsheet. for example, there are numerous geographic disparities between the two collections of rare materials as shown in the american states in which works from the collections were published. while books from all 50 states are found in the physical collection (fig. 1), only 18 states are represented in the digital library (fig. 2), with new york being the state in which the highest number of books were published. as new york city has long been a major publishing center in the united states, the authors were not surprised by this. however, the subsequent states were quite different: california and utah ranked second and third for the physical collection, while massachusetts and pennsylvania claimed those spots for the digital library. the authors believe several factors might influence this discrepancy. first, works can only be added to the digital library if they are no longer in copyright, and states with longer histories of european-american settlement are more likely to have published books that are now out of copyright. furthermore, these older books are more likely to be in a fragile condition and therefore may have been digitized to decrease the amount of physical handling to which they are subjected. information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 7 figure 1. marriott library physical rare books by us state. information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 8 figure 2. marriott library digital rare books by us state. there are other discrepancies when comparing the country of publication between the physical (fig. 3) and digital collections (fig. 4). while 61% of the physical rare books were published in the united states, only 20% of the digitized works were published in this country. the authors expected to see egypt rank highly in the physical collection, as many of the rare books were purchased by former university of utah professor dr. aziz atiya to support the middle east center for research he founded; similarly high in rank, britain, germany, france, and italy were all major centers for the early printing and publishing trade in early modern europe. however, there is strong geographic bias in the digital collection, as only north america, western europe, and one african country are represented online. copyright may again play a factor, as the earliest books from non-western countries in the collection often date to the twentieth century, but a eurocentric or other bias cannot immediately be discounted. while the physical collection contains many more european imprints than from the global south, it is much more diverse than the digital collection. information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 9 figure 3. marriott library physical rare books by country. information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 10 figure 4. marriott library digital rare books by country. the analysis of the subjects represented in the collection proved to be somewhat challenging to study. due to the nature and structure of library of congress subject headings, which attempt to mirror natural language and may be composed of “strings” of phrases to represent complex topics, no tableau public visualization could be created that effectively grouped similar content areas together without looking quite fragmented. instead, the authors based their analysis of subjects on library of congress classification numbers (i.e., call numbers) assigned to works, which, though not exact, can be understood as distillations of the subject of a work.8 once again there were considerable differences between the physical and digital rare books collections (fig. 5). as in many generalized special collections, literature and history make up significant portions of the physical collection. however, works on bibliography, or the study of books and book history, comprise a notable percentage of the collection. many of these are modern works on book history and special collections librarianship and therefore are unable to be digitized due to copyright law. nearly 9% of the digital collection is on the sciences, though these works comprise only 3% of the physical collection. while this portion of the holdings may be relatively small, it contains many scientific high points such as vesalius’ de humani corporis fabrica, early printings of ancient mathematical texts, and the journals of major scientific societies, which may have been digitized both for physical preservation as well as high interest on the part of students and faculty on campus. information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 11 figure 5. percentage of rare books physical and digital collections by library of congress class. next steps now that the first phase of the project is complete, the authors would like to conduct additional analyses. first, they plan to compare the usage statistics of the digital rare books collection to the circulation statistics of the physical collection. this method of inquiry was not possible at the start of the project, as circulation information for the rare books was previously not tracked in the integrated library system. now that rare books are checked out to patrons for use in the special collections reading room, this data can be quickly pulled from alma. once there is a year’s worth of circulation data for the rare books unhindered by the changes necessitated by the coronavirus pandemic, the authors will compare the usage statistics of the digital collection for the same time period. do patrons in the reading room look at similar materials to online patrons, or are their interests vastly different? are some rare books used so frequently that they would benefit from the added physical security that digitization brings? information technology and libraries june 2022 rarely analyzed | mccormack and wittmann 12 the authors also plan to pull annual usage statistics from the digitized rare books and share this with special collections division leadership. online patrons are still library patrons, and the division can use the viewing data to show the national and international reach of the collection. relatedly, the authors will investigate the digital library usage data in more depth. do patrons from utah, the united states, and the world look at similar materials, or are there geographic divides among the online patrons? do countries that are home to a majority of the university’s international student body have higher viewership numbers? finally, the authors wish to convene a group of stakeholders to create a formal collection development plan for the rare books component of the digital library. given the library’s limited resources, it is imperative that digitization be done thoughtfully and systematically. there is a good rationale for creating a digital collection that is representative of the physical rare books collection as well as one that highlights certain collection areas. both material fragility and the modern scholarly emphasis on highlighting the stories of people of color, women, and other underrepresented groups in library collections provide strong counterarguments to making digital libraries strictly representative of their physical counterparts. since informal conversations with patrons of the marriott library revealed that they assumed the digital library was representative of the collection overall, it is imperative that this assumption be either confirmed or disclaimed in a publicly viewable statement. in the case of the rare books department, the authors are in favor of a focused, rather than representative, collection development policy. firstly, many of the books in the collection are under copyright and therefore cannot be digitized, while other materials like reference sources for rare books librarians will be of limited interest to the general public. furthermore, complex items such as artists’ books are often poor candidates for digitization, as they may have movable components that cannot be captured accurately in a still photograph. as for what should be included online, the authors fully support equity, diversity, and inclusion efforts at the university of utah and would like to see the digital library highlight materials from marginalized groups whenever possible. usage statistics from the physical and digital collections, when they become available, should also inform the collection development policy to encourage traffic to the digital library. whatever is ultimately decided, however, the clarity a written policy provides will help streamline decision-making and ultimately help both library staff and patrons understand and search within the digital library much more effectively. endnotes 1 bart ooghe and dries moreels, “analysing selection for digitisation: current practices and common incentives,” d-lib magazine 15, no. 9/10 (2009),

metadata transformation & visualization creation analysis next steps endnotes transitioning from xml to rdf: considerations for an effective move towards linked data and the semantic web juliet l. hardesty information technology and libraries | march 2016 51 introduction metadata, particularly within the academic library setting, is often expressed in extensible markup language (xml) and managed with xml tools, technologies, and workflows. software tools such as the oxygen xml editor and querying languages such as xpath and xquery over time have become capable of helping that management. however, managing a library’s metadata currently takes on a greater level of complexity as libraries are increasingly adopting the resource description framework (rdf). semantic web initiatives are surfacing in the library context with experiments in publishing metadata as linked data sets, bibframe development using rdf, and software developments such as the fedora 4 digital repository using rdf. challenges are evident when considering examples of transitions from xml into rdf and show the need for communication and coordination between efforts to incorporate and implement rdf. this article outlines these challenges using different use cases from the literature and first-hand experience. the follow-up discussion considers ways to progress forward from metadata formatted in xml to metadata expressed in rdf. the options explored are not only targeted to metadata practitioners considering this transition but also to programmers, librarians, and managers. literature review and concepts as an initial example of the challenges faced when considering rdf, clarifying terminology is still a helpful activity. rdf focuses on sets of statements describing relationships and meaning. these statements consist of a subject, a predicate, and an object (i.e., an article, has an author, jane smith). these statement parts are also referred to as a resource, a property, and a property value. since there are three parts to rdf statements, they are referred to as triples. the predicate or property of an rdf statement defines the relationship between the subject and the object. rdf ontologies are sets of properties for a particular domain. for example, darwin core has an rdf ontology to express biological properties,1 and ebucore has an rdf ontology to express properties about audiovisual materials.2 pulling apart the many issues involved in moving from xml to rdf is an exploration into the juliet l. hardesty (jlhardes@iu.edu) is metadata analyst at indiana university libraries, bloomington, indiana. mailto:jlhardes@iu.edu transitioning from xml to rdf | hardesty doi: 10.6017/ital.v35i1.9182 52 purpose of metadata, the tools available and their capabilities, and the various strategies that can be employed. poupeau rightly states that xml provides structural logic in its hierarchical identification of elements and attributes, where rdf provides data logic declaring resources that relate to each other using properties.3 these properties are ideally all identified with single reference points (uniform resource identifiers or uris) rather than a description encased in an encoding. a source of honest confusion, however, is that rdf can be expressed as xml. lassila’s note regarding the resource description framework specification from the world wide web consortium (w3c) states, “rdf encourages the view of ‘metadata being data’ by using xml (extensible markup language) as its encoding syntax.”4 so even though rdf can use xml to express resources that relate to each other via properties, identified with single reference points (uris), rdf is itself not an xml schema. rdf has an xml language (sometimes called, confusingly, rdf, and from here forward called rdf/xml). additionally, rdf schema (rdfs) declares a schema or vocabulary as an extension of rdf/xml to express application-specific classes and properties.5 simply speaking, rdf defines entities and their relationships using statements. there are various ways to make these statements, but the original way formulated by the w3c is using an xml language (rdf/xml) that can be extended by an additional xml schema (rdfs) to better define those relationships. ideally, all parts of that relationship (the subject, predicate, object, or the resource, property, property value) are uris pointing to an authority for that resource, that property, or that property value. an additional concept worth covering is serialization. this term is used as a way to describe how rdf data is expressed using various formatting languages. rdf/xml, n-triples, turtle, and jsonld are all examples of rdf serializations.6 describing something as being in rdf really means the framework of subject, predicate, object is being used. describing something as being expressed in rdf/xml or json-ld means that the rdf statements have been serialized into either of those formatting languages. using “rdf” to refer not only to the framework to describe something (rdf) but also the serialization of that description (rdf/xml) can easily muddle the discussion. other thoughts about the difference between xml and rdf or moving metadata from xml into rdf point to the difference in perspective and the change in thinking that is required to manage such a move. in an online discussion about rdf in relation to tei (text encoding initiative), cummings talks about the need for both xml and rdf, using xml to encode text and rdf to extract that data and make it more useful.7 yee, in her in-depth look at bibliographic data as part of the semantic web, points out that rdf is designed to encode knowledge, not information.8 the rdf primer 1.0 also states “rdf directly represents only binary relationships.”9 xml describes what something is by encoding it with descriptive elements and attributes. rdf, on the other hand, constructs statements about something using direct references—a reference to the thing itself, a reference to the descriptor, and a reference to the descriptor’s value. as farnel discussed in her 2015 open repositories presentation about the university of alberta’s move to rdf, they learned they were moving from a records-based framework in xml to a things-based framework in rdf.10 what is pointed out here time and again is something else farnel discussed—moving from xml to information technology and libraries | march 2016 53 rdf is not simply a conversion between encoding formats; it is a translation between two different ways of organizing knowledge. it involves understanding the meaning of the metadata encoded in xml and representing that meaning with appropriate rdf statements. the tools most commonly employed for reworking xml into rdf are openrefine when accompanied by its rdf extension; a triplestore database such as openlink virtuoso,11 apache fuseki,12 or sesame13; oxygen xml editor14; and protégé,15 an ontology editor. openrefine is, according to the website, “a powerful tool for working with messy data: cleaning it; transforming it from one format into another; and extending it with web services and external data.”16 the rdf extension, called rdf refine, allows for importing existing vocabularies and reconciling against sparql endpoints (web services that accept sparql queries and return results).17,18 sparql is similar to sql as a language for querying a database, but the syntax is specifically designed to allow for querying data formatted in triple statements instead of tables with columns.19 triplestore databases such as openlink virtuoso can store and index rdf statements for searching as a sparql endpoint, offering a way to retrieve information and visualize connections across a collection of triples. oxygen xml editor has proven helpful in formulating extensible stylesheet language (xsl) transformations to move metadata from a particular xml schema or format into rdf/xml or other serializations such as json-ld (javascript object notation for linking data).20 protégé is a tool developed by stanford university that supports the owl 2 web ontology language and has helped to convert xml schemas to rdf ontologies and establish ways to express xml metadata in rdf. these tools provide the technical means to take metadata expressed in xml and physically reformat it to metadata expressed in an rdf serialization. what that reformatting also encompasses, however, is a review of the information expressed in xml and a set of decisions as to how to express that information as rdf statements. strategic approaches and ideas for handling data transformations into rdf have involved the xml schema or document type definition (dtd). these include thuy, lee, and lee’s approach to map an xml schema (the xsd) to rdf, associating simpletype’s xsd in xml with properties in rdf, defining complextype’s xsd in xml as classes in rdf, and handling a hierarchy of xml schema elements with top levels as domains and lower-level elements and attributes as container classes or subproperties in those domains.21 thuy et al. earlier worked on a method to transform xml to rdf by translating the dtd using rdfs (elements in the dtd are rdf classes or subclasses, attlists are rdf properties, and entities—preset variables in the dtd—are called up for use in rdf as encountered).22 similarly, hacherouf, bahloul, and cruz translate an xml schema into an owl ontology.23 klein et al. point out that while ontologies serve to describe a domain, xml schemas are meant to provide constraints on documents or structure for data so it can be advantageous to work out an rdf expression this way.24 tim berners-lee puts it simply: “the same rdf tree results from many xml trees,” meaning the same single statement in rdf (an article has an author jane smith) can be expressed in many ways in xml and can vary on the basis of the source of the xml, any schemas involved, and the people creating the metadata.25 transitioning from xml to rdf using the xml schema might serve to ensure all xml elements are transitioning from xml to rdf | hardesty doi: 10.6017/ital.v35i1.9182 54 replicated in rdf but does not necessarily establish the relationships meant by that xml encoding without additional evaluation. there is no single strategy that will always work to move xml metadata into rdf, even within the same set of tools (such as fedora/hydra) or the same area of concern (libraries, archives, or museums). use cases for rdf the following use cases explain approaches to transition to rdf taken from two differing perspectives. the first set describes efforts to express xml schemas or standards as rdf ontologies. the second set describes efforts by various library or cultural-heritage digital collections to transform metadata records into rdf statements. they also show that strategies to transform xml to rdf cannot occur without a shift in view from structure to relationships and, likewise, from descriptive encoding to direct meaning. moving an xml schema/standard to an rdf ontology as a graduate student at kent state university, mixter took on converting the descriptive metadata standard vra core 4.0 from an xml schema to an rdf ontology.26 using the vra data standards committee guidelines to ensure all minimum fields were included,27 mixter mapped vra xml elements and attributes to schema.org, foaf, void, and dc terms ontologies. this process is known as “cherry-picking,” or combining various ontologies that already exist to represent properties or relationships (the predicates in rdf statements) as rdf instead of creating new proprietary rdf properties. using owl and rdfs as metavocabularies in protégé, this created an ontology that could “retain the granularity required to describe library, archive, or museum items” of vra core 4.0’s design in xml without being a straight conversion of vra core 4.0 from xml to rdf.28 the outcome was an xslt stylesheet that was tested on vra core 4.0 xml records to produce that same information as rdf statements. one point that seemed to help in testing was the fact that all controlled vocabulary terms had reference identifiers in the xml (ready-made uris). something not discussed in the outcomes was that dates resulted in complex rdf (rdf statements that encompass additional rdf statements or blank nodes) and there was no discussion about this complexity or its effect on using those particular rdf statements. vra core 4.0 now has an rdf ontology in draft form, with mixter as one of its authors.29 the owl ontology still points to schema.org, foaf, and void for equivalent classes and properties, but everything is now named within a vra rdf ontology and namespace and translates to such when vra core 4.0 xml is transformed to rdf. another case in the category of going from an xml standard to an rdf ontology is the development of the bibframe model for bibliographic description from the library of congress. the bibframe model is expressed as rdf. according to the bibframe site, “in addition to being a replacement for marc, bibframe serves as a general model for expressing and connecting bibliographic data.”30 marc has its own format of expression with numbered fields and subfields but can be expressed or serialized in xml and is often shared that way. the bibframe model, information technology and libraries | march 2016 55 while revamping the way a bibliographic record is described on the basis of work, instance, authority, and annotation, also provides tools to transform records from marc/xml to the rdf statements of bibframe.31 a single namespace serves the bibframe model and is explained as a long-term strategy to ensure namespace persistence over the next forty-plus years.32 the transformations produced from library of congress marc records and local marc records contain complex hierarchical rdf statements, particularly when ascribing authority sources to names, subjects, and types of identifiers. as it is still a work in progress there are no tools making use of bibframe records in rdf. an additional example is the work happening with pbcore, the public broadcasting metadata standard managed by the corporation for public broadcasting.33 public broadcasting stations and other institutions across the united states provide descriptive, technical, and structural metadata for audiovisual materials using this xml standard. in boston, wgbh’s use of pbcore coincides with its digital asset management system, hydradam, built on fedora 3 and the hydra technology stack (based on blacklight, solr, and the fedora digital repository).34 fedora 3 does not natively support rdf statements as properties on objects like fedora 4. building off an interest to move hydradam to fedora 4 and leverage rdf for metadata about audiovisual collections, wgbh began exploring transitioning the pbcore xml metadata standard into an rdf ontology. ebucore, the european broadcasting union’s metadata standard, is already expressed as an rdf ontology.35 a comparison between the xml standard of pbcore and the classes and properties expressed in ebucore revealed that most pbcore elements were covered by the ebucore ontology.36 efforts are ongoing to offer pbcore 3.0 as an rdf ontology that uses ebucore with the addition of a smaller set of properties along with a way to transform pbcore xml to pbcore 3.0 in rdf.37 the hydra community, in an effort to help the transition from fedora 3 with its xml binary files of descriptive metadata to fedora 4 using rdf statements as properties on objects, is working on a recommendation and transformation to move descriptive metadata in mods xml into rdf that is usable in fedora 4.38 the mods standard has a draft of an rdf ontology and a stylesheet transformation available,39 but the complex hierarchical rdf produced from this transformation is unmanageable with the current fedora 4 architecture. the hydra mods and rdf descriptive metadata subgroup is attempting to reflect the mods elements in simple rdf statements that can be incorporated as properties on a fedora 4 digital object.40 led by steven anderson at the boston public library, this group is moving through mods element by element, asking the question, “if you had to express this mods element from your metadata in rdf today, how would you do that?” participating institutions are reviewing their mods records and exploring the possible rdf predicates that could be used to represent the meaning of that information. some are even considering how to construct those rdf statements so that mods xml can be re-created as close to the original mods as possible (this is called “round tripping”). there are still questions as to whether every single mods element will be reflected in this transformation, how exactly fedora 4 will make use of these descriptive rdf statements, and if the original mods xml will need to be preserved as part of the digital object in fedora, but this group is recognizing that moving from transitioning from xml to rdf | hardesty doi: 10.6017/ital.v35i1.9182 56 fedora 3 to fedora 4 requires a major shift in thinking about descriptive metadata. this transformation tool is an effort to help make that transition possible. the avalon media system is an open source system for managing and providing access to large collections of digital audio and video.41 it is built on fedora 3 and the hydra technology stack and uses mods xml to store descriptive metadata. as development progresses and the available descriptive fields expand, maintaining the workflow to update xml records in fedora and reindexing objects in the hydra interface becomes increasingly complicated. each time an update is made to descriptive information about an audiovisual item through the avalon interface, the entire xml record for that object, stored as a binary text file, is rewritten in fedora 3 and reindexed in solr. in considering advantages to using fedora 4, it appears that descriptive metadata properties stored in rdf are easier to manage programmatically (updating content, adding new fields, more focused reindexing) because descriptive information would not be stored in a single binary file but as individual properties on the object. turning xml metadata into rdf or linked data for publishing, search and discovery, and management as southwick describes the process, the library at the university of nevada las vegas (unlv) took a collection with descriptive records from contentdm and published them as a single rdf linked open data set.42 after cleaning up controlled vocabulary terms across collections and solidifying locally controlled vocabularies, they exported tab-delimited csv records from contentdm. these records were brought into openrefine with its rdf extension where they reviewed the data and mapped to various properties within the europeana data model (edm). controlled vocabulary terms were in text form and had to be reconciled against a sparql endpoint, either locally from downloaded data or from the controlled vocabulary service, to gather the uris to use as the object or value in the rdf statement. openrefine was then used to create rdf files that were uploaded to a triplestore (first mulgara then openlink virtuoso). this provided public access to the linked open data set and a sparql endpoint for querying the data set. after publishing the data set they experimented with pivotviewer from openlink virtuoso and relfinder to see what kinds of connections and relationships could be visualized from the data as linked open data. the outlined steps are clear and the outcomes are described, but interestingly the data set itself no longer appears to be available online.43 although the unlv use case relies on csv instead of xml as the data source, the tools and workflows enlisted to transform the data set into rdf linked open data are still applicable. openrefine can import xml just as it imports csv, so this described case shows the tools that can be used and decisions to be made in processing that data into rdf statements. in oregon digital,44 xml from qualified dublin core, vra core, and mods at two different institutions (university of oregon and oregon state university) were mapped as linked open data and stored in a triplestore to be served up in a new web application using the hydra technology stack.45 an inventory of metadata fields across all collections was first mapped to existing linked information technology and libraries | march 2016 57 data terms, or properties (those with available uris), then properties that were needed in the new web application but did not have available corresponding uris were mapped to a newly devised local namespace for oregon digital. any properties that were not used were kept in the original static xml file for the record as part of the digital object in fedora. the focus here appears to be on mapping properties without as much detail provided on whether the objects were kept as text or mapped to uri values where possible. from the sample record provided the objects appear to be text and not uris. the real power of this project is finding common properties to describe objects from diverse collections and institutions. what also comes out in the example mappings is the use of many different namespaces or ontologies (dc terms, marc relators, but also mods and mads that produce complex rdf). the university of alberta also combined a variety of xml metadata from different sources into a new digital asset management system based on fedora 4 and the hydra technology stack, called the education and research archive.46 reporting on the experience at open repositories 2015, farnel described the process as working in phases.47 beginning with item types, languages, and licenses, then moving to place names and controlled subject terms, and finally person names and free-form subjects, they made multiple passes converting xml metadata into rdf statements and incorporating uris whenever possible. they are combining all of this into a single data dictionary,48 making use of several rdf ontologies to cover the various metadata properties that are being described about objects and collections. university of california at san diego (ucsd) has developed a local data model using a mix of external (mads, vra core, darwin core, premis) and local ontologies. they published a data dictionary and are working on a substantially different revision as part of the metadata workflow they use to bring digital objects into their digital asset management system from a variety of source metadata formats including xml.49 this allows metadata to be created from disparate source formats and makes it possible to bring them together as rdf for delivery, management, and preservation. discussion if metadata is in xml form and the desire is to express it as rdf, this is not merely a transformation from one xml schema to another. it is changing the expression of that data and changing its use. having metadata in xml means information is encoded in a specific way that allows for interchange and sharing. having metadata in rdf is making statements that have direct meaning and can be used independently. there are different perspectives involved in metadata when approaching rdf: those that manage metadata standards (the xml standard side) and those that have metadata encoded using those xml standards (the data management side). depending on the desired outcomes, the needs of these two perspectives can conflict. when managing a metadata standard the rdf transition tends to follow certain patterns: transitioning from xml to rdf | hardesty doi: 10.6017/ital.v35i1.9182 58 • transform an xml standard into a new rdf ontology o examples: dublin core (dc), darwin core (dwc), mods, vra core • establish a move to rdf that incorporates another existing ontology o example: pbcore, hydra community from the data management side, the rdf transition means different patterns occur. these scenarios often start by reviewing the needed outcome, deciding how much metadata needs to be expressed in rdf, and what works best to get the metadata to that point. cases include the following commonalities: • creating new search and discovery end user applications o example: oregon digital, university of alberta • publishing linked data sets o example: unlv, university of alberta • managing metadata using software that supports rdf o example: university of alberta, ucsd, hydra community conflicts are occurring when the needed outcome on the data management side is not supported by the rdf ontology transitions that have occurred for the xml standards being used. an example of this is how rdf is handled in fedora 4. when rdf is complex (the object of one statement is another entire rdf statement), fedora produces blank nodes as new objects within the repository. while not technically problematic, descriptive metadata with complex rdf can result in a situation where a digital object ends up referencing a blank node that then points to, for example, a subject or a genre. this subject or genre has been created as its own object within the digital repository even though that subject or genre is only meant to provide meaning for the digital object. mods rdf produces this complexity and thus is not workable to use with fedora 4. in contrast, other standards such as dc or dwc in rdf produce simple statements that fedora 4 can apply to a digital object without any additional processing. complications in transitioning from xml to rdf also occur when the original xml does not include uris or authority-controlled sources. converting this metadata to rdf can mean locally minting uris or bringing data over as literals (strings of text) without using uris at all. ideally, the result is somewhere in the middle with externally controlled vocabularies incorporated as much as possible and literals or locally minted uris only used where absolutely necessary. translating strings to authoritative sources is intensive work. if the xml standard cannot be expressed as a single rdf ontology, work is further complicated by the need to map xml elements to different rdf ontologies using logic that is often decided locally. while it is possible to transition xml to rdf, the process is not uniform and the pathway involves a lot of labor. potential alleviators for this labor might involve a more user-centered approach by xml standard bodies to consider the ways their standards can be used when translated into rdf (“users” in this context meaning the users of the standards, not the end users searching and information technology and libraries | march 2016 59 discovering digital content). triplestores can manage queries for complex rdf, but digital repository systems are not there yet. those that support rdf for description of objects do so on the basis of simple property statements. a complex rdf ontology is going to be a challenge to support over time. another way to progress forward is for the data management side of the equation to focus efforts on showing, in an end user search and discovery format, what is currently possible when xml is transitioned into rdf. published linked data sets need to have interfaces for access and use, showing the value of what is currently available and any needs or gaps that remain. libraries and cultural-heritage organization engaged in this work should also openly share the processes that both work and do not work so others contemplating this transformation can consider how to forge ahead themselves. libraries and cultural-heritage organizations moving metadata from xml to rdf should provide feedback to xml standard bodies regarding the usefulness or complications of any rdf transitional help an xml standard might provide. technologies for incorporating rdf into web applications and truly connecting triples across the web also require further work. triplestores have so far been the main way to expose data sets but have not been incorporated into common library or cultural-heritage end user search and discovery web applications. additionally, triplestore use does not seem to extend to management or long-term storage of complete data about digital objects. there seems to be a decision to either reduce the data stored in a triplestore down to simple statements or use the triplestore more like an isolated index or sparql endpoint only and manage the complete metadata record separately (in a static file containing text or in a separate database). that aligns triples in rdf more with relational database storage than with catalog records. triple statements focus on relationships and not the complete unique details of the thing being described. triplestores can handle complex hierarchical rdf graphs and provide responses on the basis of queries against those complexities,50 but triplestores do not appear to be taking over as either the main search and discovery mechanism for online digital resources or for digital object management. software using rdf natively is also not currently widespread. a project such as the bibframe initiative that plans to incorporate rdf needs to make sure the complexity of its data model in rdf is manageable by any tools it produces and that it is possible for vendors and suppliers to encompass the data model in their software development. conclusion the reasons for deciding metadata should transition to rdf are just as important as determining the best process for implementing that transition. reasons for transitioning to rdf are conceptually based around making data more easily shareable and setting up data to have meaning and relationships as opposed to local static description that requires programmatic interpretation. the use cases outlined in this article show the reality does not quite yet match the concept. transitioning an xml standard to rdf does not make that data more shareable or more easily understood unless there are end user applications for using that data in rdf. publishing transitioning from xml to rdf | hardesty doi: 10.6017/ital.v35i1.9182 60 linked data involves going through transitional steps, but the endpoint seems to be more of a byproduct. the real goal is going through the process of producing linked data to learn how that works. self-contained projects that aim to express collections in rdf for the purpose of a new search and discovery interface are more successful in implementing rdf that has that new level of meaning and relationship. beyond the borders of these projects, however, the data is not being shared or used. the use cases described above show some examples of what is happening now when transitioning from xml to rdf. approaches include xml standards converting to rdf expression as well as digital collections with metadata in xml that have an interest in producing that metadata as rdf. software that incorporates rdf is still developing and maturing. helping that process along by providing a pathway from xml to functionally usable rdf improves the chances of the semantic web becoming a real and useful thing. it is vital to understand that transitioning from xml to rdf requires a shift in perspective from replicating structures in xml to defining meaningful relationships in rdf. metadata work is never easy, and for metadata to move from encoded strings of text to statements with semantic relationships requires coordination and communication. how best to achieve this coordination and communication

anxiety: the role of computer attitudes jiao, qun g;onwuegbuzie, anthony j information technology and libraries; dec 2004; 23, 4; proquest pg. 138 the impact of information technology on library anxiety: oun g. jiao and anthony j. onwuegbuzie the role of computer attitudes over the past two decades, computer-based technologies have become dominant forces to shape and reshape the products and services the academic library has to offer. the application of library technologies has had a profound impact on the way library resources are being used. although many students continue to experience high levels of library anxiety, it is likely that the new technologies in the library have led to them experiencing other forms of negative affective states that may be, in part, a function of their attitude towards computers. this study investigates whether students' computer attitudes predict levels of library anxiety. c omputers and information technologies have experienced considerable growth over the past two decades. as such, familiarity with computers is rapidly becoming a basic skill and a prerequisite for many tasks. although not every college student is equally prepared for the rising demand of computer skills in the !nformation age, computer literacy is increasingly becommg a gatekeeper for students' academic success. 1 gaps in computer literacy and skills can leave many students behind not only in their academic achievement but also in their future job-market success. the unprecedented pace of technological change in the development of digital information networks and electronic services in recent years has helped to expand the role of the academic library. once only a storehouse of printed materials, it is now a technology-laden information network where students can conduct research in a mixed print and digital-resource environment, experience the use of advanced information technologies, and hone their computer skills. yet, many students are struggling to cope with the changes brought on by the rapid advances of information teclmologies. academic libraries of various sizes have spent a large percentage of their material budget on electronic commercial content, and the trend will continue.' these days, college students are faced with the choices of ever-changing modes of electronic accessing tools, interfaces, and protocols along with the traditional print resources in the library. the fact that the same journal article may be available in multiple vendors' aggregator oun g. jiao (gerryjiao@baruch.cuny.edu) is reference libraria~ and_ associate professor at newman library, baruch college, city university of new york, and anthony j. onwuegbuzie (tony onwuegbuzie@aol.com) is associate professor at the college of education, university of south florida, tampa. sites (such as ebscohost and gale group) makes the navigation through these bibliographic databases more complex and challenging. relevant sources must be identified and navigation protocols must be learned before appropriate information and contents can be found. furthermore, having located a citation, students still have to search the library online catalog to find out if the journal or book is available in the library and, if not, know how to make an interlibrary loan request either on paper or electronically.' anxiety levels can be high and patience levels can be low at varying times of conducting library research. 4 . that students experience various levels of apprehension when using academic libraries is not a new phenomenon. indeed, the phenomenon is prevalent among college students in the united states and many other countries, and is widely known as library anxiety. mellon first coined the term in her study in which she noted that 75 percent to 85 percent of undergraduate students described their initial library experiences in terms of anxiety.5 according to mellon, feelings of anxiety stem from either the relative size of the library; a lack of knowledge about the location of materials, equipment, and resources of the library; how to initiate library research; or how to proceed with a library search. 6 library anxiety is an unpleasant feeling or emotional state with physiological and behavioral concomitants that come to the fore in li_brary settings. typically, library-anxious students experience negative emotions, including ruminations, tension, fear, and mental disorganization, which prevent them from using the library effectively. 7 a student who experiences library anxiety usually undergoes either emotional ~r physical discomfort when faced with any library or library-related task. 8 library anxiety may arise from a lack of self-confidence in conducting research, lack of prior exposure to academic libraries, the inability to see the relevance of libraries to one's field of interest, and lack of familiarity with library equipment and technologies. library anxiety is often accorded special attention because of its debilitating effects on students' academic achievement.9 although many students continue to experience high levels of library anxiety, it is likely that the new technologies and electronic databases in libraries have led to students experiencing other forms of negative affective states. in particular, it is likely that library anxiety experienced by students is, in part, a function of their attitudes toward computers. consistent with this assertion, mizrachi and shoham and mizrachi reported a statistically significant relationship between library anxiety and computer attitudes. 10 they noted in their research that home and work usage of computers, computer games, word processors, computer spreadsheets, and the internet are all related to the dimensions of library anxiety found among israeli students to varying degrees. 138 information technology and libraries i december 2004 reproduced with permission of the copyright owner. further reproduction prohibited without permission. similarly, jerabek, meyer, and kordinak found levels of computer anxiety to be related to levels of library anxiety for both men and women. 11 these studies focused exclusively on undergraduate students. however, no study has examined this relationship among graduate students, a population that uses the academic library more than any other student population. over the past fifteen years, a large body of research literature on computer attitudes has been generated. in particular, many researchers have studied the relationship between computer attitudes and computer use. 12 the importance of beliefs and attitudes towards computers and technologies is widely acknowledged. 13 students' computer attitudes arguably impact their willingness to engage in computer-related activities in colleges and universities where effectively using library electronic resources represents an increasingly important part of college education. negative computer attitudes may inhibit students' interests in learning to use the library resources and thereby weaken their academic performance levels, while at the same time elevating levels of library anxiety. mclnerney, mclnerney, and sinclair observed that negative perceptions about computers among student teachers may accompany feelings of anxiety, including worries about being embarrassed, looking foolish, and even damaging the computer equipment. 14 further, there is often a negative relationship between prior experience with computers and computer anxiety experienced by individuals. 15 until recently, library anxiety has only been interpreted in the context of the library setting-that is, a phenomenon that occurs while students are undertaking library tasks. jiao, onwuegbuzie, and lichtenstein defined library anxiety as "an uncomfortable feeling or emotional disposition, experienced in a library setting, which has cognitive, affective, physiological, and behavioral ramifications." 16 at the same time, unprecedented technological advancement has had a profound impact on the products and services offered by academic libraries. students now are able to conduct sophisticated library searches from the comfort of their homes. it is clear that the construct of library anxiety needs to be expanded in the new library and information environment, incorporating into its definition other variables that are relevant for the changing library and information context. because many library users spend a significant portion of their time using computer-based technologies to conduct information searches, it is natural to ask, to what extent does library anxiety stem from students' prior attitudes and experiences with computers and library technologies? however, with the exception of the studies conducted by mizrachi and shoham and mizrachi on israeli undergraduate students, this link has not been examined. 17 thus, the present study investigated the relationship between computer attitudes and library anxiety in the rapidly changing library and information environment. as such, the current inquiry replicated the works of mizrachi, shoham and mizrachi, and jerabek, meyer, and kordinak by examining the degree to which computer attitudes predict levels of library anxiety among graduate students in the united states. 18 it was expected that findings from this study would help to increase the understanding of the construct of library anxiety. indeed, research in this area has become critical in higher education where educators are responsible for graduating students with the skills necessary to thrive and to lead in a rapidly changing technological environment in the twenty-first century. i method participants participants were ninety-four african american graduate students enrolled in the college of education at a historically black college and university in the eastern u.s. all participants were solicited in either a statistics or a measurement course at the time that the investigation took place. in order to participate in the study, students were required to sign an informed-consent document that was given during the first class session of the semester. the majority of the participants were female. ages of the participants ranged from twenty-two to sixty-two years (mean = 30.40, sd = 8.75). instruments and procedure all participants were administered two scales, namely, the computer attitude scale (cas) and the library anxiety scale (las). the cas, developed by loyd and gressard, contains forty likert-type items that assess individuals' attitudes toward computers and the use of computers. 19 this instrument consists of the following four scales, which can be used separately: (1) anxiety or fear of computers; (2) confidence in the ability to use computers; (3) liking or enjoying working with computers; and (4) computer usefulness. loyd and gressard reported coefficient alpha reliability coefficients of .86, .91, .91, and .95 for scores pertaining to computer anxiety, computer confidence, computer liking, and total scales, respectively. for the present study, the score reliabilities were as follows: • computer anxiety, .84 (95 percent confidence interval ci = .79, .88); • computer confidence, .81 (95 percent ci = .75, .86); • computer liking, .89 (95 percent ci= .85, .92); and • computer usefulness, .76 (95 percent ci = .68, .83). the impact of information technology on library anxiety i jiao and onwuegbuzie 139 reproduced with permission of the copyright owner. further reproduction prohibited without permission. the las, developed by bostick, contains forty-three 5-point likert-format items that assess levels of library anxiety experienced by college students. 20 it also contains the following five subscales: 1. barriers with staff; 2. affective barriers; 3. comfort with the library; 4. knowledge of the library; and 5. mechanical barriers. a high score on any subscale represents high levels of anxiety in that area. jiao and onwuegbuzie, in their examination of the score reliability reported on las in the extant literature, found that it has typically been in the adequate to high range for the subscale and total-scale scores. 21 based on their analysis, onwuegbuzie, jiao, and bostick concluded that "not only does the [las] produce scores that yield extremely reliable estimates, but also these estimates are remarkably consistent across samples with different cultures, nationalities, ages, years of study, gender composition, educational majors, and so forth." 22 for the current investigation, the subscales generated scores for the combined sample that had a classical theory alpha reliability coefficient of .89 (95 percent ci = .85, .92) for barriers with staff, .84 (95 percent ci = .79, .88) for affective barriers, .53 (95 percent ci= .37, .66) for comfort with the library, .62 (95 percent ci= .48 .73) for knowledge of the library, and .70 (95 percent ci= .58, .79) for mechanical barriers. analysis a canonical correlation analysis was conducted to identify a combination of library anxiety dimensions (barriers with staff, affective barriers, comfort with the library, knowledge of the library, and mechanical barriers) that might be simultaneously related to a combination of computer-attitude dimensions (computer anxiety, computer liking, computer confidence, and computer usefulness). canonical correlation analysis is used to examine the relationship between two sets of variables whereby each set contains more than one variable. 23 in the present investigation, the five dimensions of library anxiety were treated as the dependent multivariate set of variables, and the four dimensions of computer attitudes formed the independent multivariate profile. the number of canonical functions (factors) that can be produced for a given dataset is equal to the number of variables in the smaller of the two variable sets. because the library-anxiety set contained five dimensions and the computer-attitude set contained four variables, four canonical functions were generated. for any significant canonical coefficient, the standardized canonical-function coefficients and structure coefficients were then interpreted. standardized canonicalfunction coefficients are computed weights that are applied to each variable in a given set in order to obtain the composite variate used in the canonical correlation analysis. as such, standardized canonical-function coefficients are equivalent to factor-pattern coefficients in factor analysis or to beta coefficients in a regression analysis." conversely, structure coefficients represent the correlations between a given variable and the scores on the canonical composite (latent variable) in the set to which the variable belongs.2 5 thus, structure coefficients indicate the degree to which each variable is related to the canonical composite for the variable set. indeed, structure coefficients are essentially bivariate correlation coefficients that range in value between -1.0 and + 1.0 inclusive." the square of the structure coefficient yields the proportion of variance that the original variable shares linearly with the canonical variate. i results table 1 presents the intercorrelations among the five dimensions of library anxiety and the four dimensions of computer attitude. of particular interest were the twenty correlations between the library-anxiety subscale scores and the computer-attitude subscale scores. it can be seen that, after applying the bonferroni adjustment, four of these relationships were statistically significant. specifically, computer liking was statistically significantly related to affective barriers, knowledge of the library, and comfort with the library. using cohen's criteria of .1, .3, and .5 for small, medium, and large relationships, respectively, the first two relationships (involving affective barriers and knowledge of the library) were medium, and the third relationship (between computer liking and comfort with the library) was large. 27 in addition to these three relationships, the association between computer usefulness and knowledge of the library also was statistically significant, with a medium effect size. the correlation matrix in table 1 was used to examine the multivariate relationship between library anxiety and computer attitudes. this relationship was assessed via a canonical correlation analysis. the canonical analysis revealed that the four canonical correlations combined were statistically significant (p < .0001). also, when the first canonical root was removed, the remaining three canonical roots were not statistically significant. in fact, removal of subsequent canonical roots did not lead to statistical significance. together, these results suggested that only the first canonical function was statistically significant, but the remaining three roots were not statistically significant. this first canonical root also was practically significant (rc1 = .63), contributing 40.8 percent (rc12) to the shared variance, which represents a large effect size. 28 140

are presented in table 2, which provides both standardized function coefficients and structure coefficients. using a cutoff correlation of 0.3, the standardized canonical-function coefficients revealed that affective barriers, comfort with the library, and knowledge of the library made important contributions to the library-anxiety set, with affective barriers and comfort with the library making similarly large contributions. 29 with regard to the computer-attitude set, computer anxiety, computer liking, and computer confidence made noteworthy contributions, with the latter two dimensions making the most noteworthy contributions. the structure coefficients revealed that all five dimensions of library anxiety made important contributions to the first canonical variate. the square of the structure coefficient indicated that barriers with staff, affective barriers, comfort with the library, and knowledge of the library made similarly large contributions, explaining 67.2 percent, 72.3 percent, 72.3 percent, and 60.8 percent of the variance, respectively. with regard to the computerattitude set, computer liking and computer usefulness made important contributions. these variables explained 64.0 percent and 16.8 percent of the variance, respectively. comparing the standardized and structure coefficients indicated that computer anxiety and computer confidence served as suppressor variables because the standardized coefficients associated with these variables were large, whereas the corresponding structure coefficients were relatively small. 30 suppressor variables are variables that assist in the prediction of dependent variables due to their correlation with other independent variables. 31 thus, the inclusion of computer anxiety and computer confidence in the canonical correlation model strengthened the multivariate relationship between library anxiety and computer attitudes. i discussion the purpose of this study was to investigate the relationship between computer attitudes and library anxiety among african american graduate students. specifically, the multivariate link between these two constructs was examined. a canonical correlation analysis revealed a strong multivariate relationship between library anxiety and computer attitudes. the library-anxiety subscale scores and computer-attitudes subscale scores shared 40.82 percent of the common variance. specifically, computer liking and computer usefulness were related simultaneously to the following five dimensions of library anxiety: barriers with staff, affective barriers, comfort with the library, knowledge of the library, and mechanical barriers. computer anxiety and computer confidence served as suppressor variables. thus, computer attitudes predict levels of library anxiety. as such, the present findings are consistent with those of mizrachi and shoham and mizrachi, who found a statistically significant relationship between computer attitudes and the following seven dimensions of the hebrew library-anxiety scale, a modified version of las developed by the authors for their israeli sample: 1. staff 2. knowledge 3. language 4. physical comfort 5. library computer comfort 6. library policies and hours, and 7. resources. 32 according to its authors, the staff factor refers to students' attitudes towards librarians and library staff and their perceived accessibility. the knowledge factor pertains to how students rate their own library expertise. the language factor relates the extent to which using englishlanguage searches and materials yield discomfort. physical comfort evaluates how much the physical facility negatively affects students' satisfaction and comfort with the library. library computer comfort assesses the perceived trustworthiness of library computer facilities and the quality of directions for using them. library policies and hours concerns students' attitudes toward library rules, regulations, and hours of operation. finally, resources refers to the perceived availability of the desired material in the library collection. the correlations between the dimensions of library anxiety and computer attitudes ranged from .11 (physical comfort) to .47 (knowledge). the current results also replicate those of jerabek, meyer, and kordinak, who found levels of computer anxiety to be related to levels of library anxiety for both men and women. 33 nevertheless, caution should be exercised in generalizing the current findings to all graduate students. though the present study examined the association between library anxiety and computer attitudes among african american graduate students, it should not be assumed that this relationship would hold for other racial groups. jiao, onwuegbuzie, and bostick found that african american students attending a research-intensive institution reported statistically significantly lower levels of library anxiety associated with barriers with staff, affective barriers, and comfort with the library than did caucasian american graduate students enrolled at a doctoral-granting institution, with effect sizes ranging from moderate to large. 34 in a follow-up study, jiao and onwuegbuzie compared african american and caucasian american students with respect to library anxiety, controlling for educational background by selecting both racial groups from the same institution. 35 no statistically significant racial differences the impact of information technology on library anxiety i jiao and onwuegbuzie 141 reproduced with permission of the copyright

anxiety for any of the five dimensions of las. however, across all five library-anxiety measures, the african american sample reported lower scores than did the caucasian american sample. in fact, using the test of trend by onwuegbuzie and levin, they found that the consistency with which the african american graduate students had lower levels of library anxiety than did the caucasian american students was both statistically and practically significant. 36 thus, jiao and onwuegbuzie's results, alongside those of jiao, onwuegbuzie, and bostick, suggest that racial differences in library anxiety prevail. 37 thus, future research should investigate whether the relationship between library anxistructure coefficient .82* .85* .85* .78* .39* -.22 .13 -.80* -.41 * structure•(%) 67.2 72 .3

other racial groups. further, the causal direction of the relationship found in the current study should be investigated. that is, future studies should investigate whether library anxiety places a person more at risk for experiencing poor computer attitudes, or whether the converse is true. more research also is needed to determine how computer attitudes might play a role in the library context. notwithstanding, it appears that the construct of library anxiety can be expanded to include the construct 142 information technology and libraries i december 2004 reproduced with permission of the copyright owner. further reproduction prohibited without permission. of computer attitudes. indeed, one implication of the findings is that bostick's las should be modified to include dimensions of computer attitudes. 38 such a modification likely would facilitate the identification of library-anxious students. by identifying students with high levels of library anxiety and poor computer attitudes, library educators and others could help them improve their dispositions and provide them with the skills necessary to negotiate the rapidly changing technological environment, thereby putting them in a better position to be lifelong learners. references 1. susan m. piotrowski, computer training: pathway from extinction (eric document reproduction service, ed 348955, 1992).

kurtz dublin core, dspace, and a brief analysis of three university repositories this paper provides an overview of dublin core (dc) and dspace together with an examination of the institutional repositories of three public research universities. the universities all use dc and dspace to create and manage their repositories. i drew a sampling of records from each repository and examined them for metadata quality using the criteria of completeness, accuracy, and consistency. i also examined the quality of records with reference to the methods of educating repository users. one repository used librarians to oversee the archiving process, while the other two employed two different strategies as part of the selfarchiving process. the librarian-overseen archive had the most complete and accurate records for dspace entries. t he last quarter of the twentieth century has seen the birth, evolution, and explosive proliferation of a bewildering variety of new data types and formats. digital text and images, audio and video files, spreadsheets, websites, interactive databases, rss feeds, streaming live video, computer programs, and macros are merely a few examples of the kinds of data that can be now found on the web and elsewhere. these new dataforms do not always conform to conventional cataloging formats. in an attempt to bring some sort of order from chaos, the concept of metadata (literally “data about data”) arose. metadata is, according to ala, “structured, encoded data that describe characteristics of informationbearing entities to aid in the identification, discovery, assessment, and management of the described entities.”1 metadata is an attempt to capture the contextual information surrounding a datum. the enriching contextual information assists the data user to understand how to use the original datum. metadata also attempts to bridge the semantic gap between machine users of data and human users of the same data. n dublin core dublin core (dc) is a metadata schema that arose from an invitational workshop sponsored by the online computer library center (oclc) in 1995. “dublin” refers to the location of this original meeting in dublin, ohio, and “core” refers to that fact dc is set of metadata elements that are basic, but expandable. dc draws upon concepts from many disciplines, including librarianship, computer science, and archival preservation. the standards and definitions of the dc element sets have been developed and refined by the dublin core metadata initiative (dcmi) with an eye to interoperability. dcmi maintains a website (http://dublincore.org/ documents/dces/) that hosts the current definitions of all the dc elements and their properties. dc is a set of fifteen basic elements plus three additional elements. all elements are both optional and repeatable. the basic dc elements are: 1. title 2. creator 3. subject 4. description 5. publisher 6. contributor 7. date 8. type 9. format 10. identifier 11. source 12. language 13. relation 14. coverage 15. rights the additional dc elements are: 16. audience 17. provenance 18. rights holder dc allows for element refinements (or subfields) that narrow the meaning of an element, making it more specific. the use of these refinements is not required. dc also allows for the addition of nonstandard elements for local use. n dspace dspace is an open-source software package that provides management tools for digital assets. it is frequently used to create and manage institutional repositories. first released in 2002, dspace is a joint development effort of hewlett packard (hp) labs and the massachusetts institute of technology (mit). today, dspace’s future mary kurtz (mhkurtz@gmail.com) is a june 2009 graduate of drexel university’s school of information technology. she also holds a bs in secondary education from the university of scranton and an ma in english from the university of illinois at urbana– champaign. currently, kurtz volunteers her time in technical services/cataloging at simms library at albuquerque academy and in corporate archives at lovelace respiratory research institute (www.lrri.org), where she is using dspace to manage a diverse collection of historical photographs and scientific publications. dc, dspace, and a brief analysis of three university repositories | kurtz 41 is guided by a loose grouping of interested developers called the dspace committers group, whose members currently include hp labs, mit, oclc, the university of cambridge, the university of edinburgh, the australian national university, and texas a&m university. dspace version 1.3 was released in 2005 and the newest version, dspace 1.5, was released in march 2008. more than one thousand institutions around the world use dspace, including public and private colleges and universities and a variety not-for-profit corporations. dc is at the heart of dspace. although dspace can be customized to a limited extent, the basic and qualified elements of dc and their refinements form dspace’s backbone.2 n how dspace works: a contributor’s perspective dspace is designed for use by “metadata naive” contributors. this is a conscious design choice made by its developers and in keeping with the philosophy of inclusion for institutional repositories. dspace was developed for use by a wide variety of contributors with a wide range of metadata and bibliographic skills. dspace simplifies the metadata markup process by using terminology that is different from dc standards and by automating the production of element fields and xml/html code. dspace has four hierarchical levels of users: users, contributors, community administrators, and network/ systems administrators. the user is a member of the general public who will retrieve information from the repository via browsing the database or conducting structured searches for specific information. the contributor is an individual who wishes to add their own work to the database. to become a contributor, one must be approved by a dspace community administrator and receive a password. a contributor may create, upload, and (depending upon the privileges bestowed upon him by his community administrator), edit or remove informational records. their editing and removal privileges are restricted to their own records. a community administrator has oversight within their specialized area of dspace and accordingly has more privileges within the system than a contributor. a community administrator may create, upload, edit, and remove records, but also can edit and remove all records available within the community’s area of the database. additionally, the community administrator has access to some metadata about the repository’s records that is not available to users and contributors and has the power to approve requests to become contributors and grant upload access to the database. lastly, the community administrator sets the rights policy for all materials included in the database and writes the statement of rights that every contributor must agree to with every record upload. the network/systems administrator is not involved with database content, focusing rather on software maintenance and code customization. when a dspace contributor wishes to create a new record, the software walks them through the process. dspace presents seven screens in sequence that ask for specific information to be entered via check buttons, fillin textboxes, and sliders. at the end of this process, the contributor must electronically sign an acceptance of the statement of rights. because dspace’s software attempts to simplify the metadata-creation process for contributors, its terminology is different from dc’s. dspace uses more common terms that are familiar to a wider variety of individuals. for example, dspace asks the contributor to list an “author” for the work, not a “creator” or a “contributor.” in fact, those terms appear nowhere in any dspace. instead, dspace takes the text entered in the author textbox and maps it to a dc element—something that has profound implications if the mapping does not follow expected dc definitions. likewise, dspace does not use “subject” when asking the contributor to describe their material. instead, dspace asks the contributor to list keywords. text entered into the keyword field is then mapped into the subject element. while this seems like a reasonable path, it does have some interesting implications for how the subject element is interpreted and used by contributors. dc’s metadata elements are all optional. this is not true in dspace. dspace has both mandatory and automatic elements in its records. because of this, data records created in dspace look different than data records created in dc. these mandatory, automatic, and default fields affect the fill frequency of certain dc elements—with all of these elements having 100 percent participation. in dspace, the title element is mandatory; that is, it is a required element. the software will not allow the contributor to proceed if the title text box is left empty. as a consequence, all dspace records will have 100 percent participation in the title element. dspace has seven automatic elements, that is, element fields that are created by the software without any need for contributor input. three are date elements, two are format elements, one is an identifier, and one is provenance. dspace automatically records the time of the each record’s creation in machine-readable form. when the record is uploaded into the database, this timestamp is entered into three element fields: dc.date.available, dc.date.accessioned, and dc.date.issued. therefore dspace records have 100 percent participation in the date element. for previously published materials, a separate screen asks for the original publication date, which is then 42 information technology and libraries | march 2010 placed in the dc.date.issued element. like title, the original date of publication is a mandatory field, and failure to enter a meaningful numerical date into the textbox will halt the creation of a record. in a similar manner, dspace “reads” the kind of file the contributor is uploading to the database. dspace automatically records the size and type (.doc, .jpg, .pdf, etc.) of the file or files. this data is automatically entered into dc.format.mimetype and dc.format.extent. like date, all dspace records will have 100 percent participation in the format element. likewise, dspace automatically assigns a location identifier when a record is uploaded to the database. this information is recorded as an uri and placed in the identifier element. all dspace records have a dc.identifier.uri field. the final automatic element is provenance. at the time of record creation, dspace records the identity of the contributor (derived from the sign-in identity and password) and places this information into a dc.provenance element field. this information becomes a permanent part of the dspace record; however, this field is a hidden to users. typically only community and network/systems administrators may view provenance information. still, like date, format, and identifier elements, dspace records have automatic 100 percent participation in provenance. because of the design of dspace’s software, all dspace-created records will have a combination of both contributor-created and dspace-created metadata. all dspace records can be edited. during record creation, the contributor may at any time move backward through his record to alter information. once the record has been finished and the statement of rights signed, the completed record moves into the community administrator’s workflow. once the record has entered the workflow, the community administrator is able to view the record with all the metadata tags attached and make changes using dspace’s editing tools. however, depending on the local practices and the volume of records passing through the administrator’s workflow, the administrator may simply upload records without first reviewing them. a record may also be edited after it has been uploaded, with any changes being uploaded into the database at the end of editing process. in editing a record after it has been uploaded, the contributor, providing he has been granted the appropriate privileges, is able to see all the metadata elements that have attached to the record. calling up the editing tools at this point allows the contributor or administrator to make significant changes to the elements and their qualifiers, something that is not possible during the record’s creation. when using the editing tools, the simplified contributor interface disappears, and the metadata elements fields are labeled with their dc names. the contributor or administrator may remove metadata tags and the information they contain and add new ones selecting the appropriate metadata element and qualifier from a slider. for example, during the editing process, the contributor or administrator may choose to create dc.contributor. editor or dc.subject.lcsh options—something not possible during the record-creation process. in the examination of the dspace records from our three repositories, dspace’s shaping influence on element participation and metadata quality will be clearly seen. n the repositories dspace is principally used by academic and corporate nonprofit agencies to create and manage their institutional repositories. for this study, i selected three academic institutions that shared similar characteristics (large, public, research-based universities) but which had differing approaches to how they managed their metadata-quality issues. the university of new mexico (unm) dspace repository (dspaceunm) holds a wide-ranging set of records, including materials from the university’s faculty and administration, the law school, the anderson school of business administration, and the medical school, as well as materials from a number of tangentially related university entities like the western water policy review advisory commission, new mexico water trust board, and governor richardson’s task force on ethic reform. at the time of the initial research for this paper (spring 2008), dspaceunm provided little easily accessible on-site education for contributors about the dspace record-creation process. what was offered—a set of eight general information files—was buried deep inside the library community. a contributor would have to know the files existed to find them. by summer 2009, this had changed. dspaceunm had a new homepage layout. there is now a link to “help sheets and promotional materials” at the top center of the homepage. this link leads to the previously difficult-tofind help files. the content of the help files, however, remains largely unchanged. they discuss community creation, copyrights, administrative workflow for community creation, a list of supported formats, a statement of dspaceunm’s privacy policy, and a list of required, encouraged, and not required elements for each new record created. for the most part, dspaceunm help sheets do not attempt to educate the contributor in issues of metadata quality. there is no discussion of dc terminology, no attempts to refer the contributor to a thesaurus or controlled vocabulary list, nor any explanation of the record-creation or editing process. this lack of contributor education may be explained in part because dspaceunm requires all new records dc, dspace, and a brief analysis of three university repositories | kurtz 43 to be reviewed by a subject area librarian as part of the dspace community workflow. thus any contributor errors, in theory, ought to be caught and corrected before being uploaded to the database. the university of washington (uw) dspace repository (researchworks at the university of washington) hosts a narrower set of records than dspaceunm, with the materials limited to the those contributed by the university’s faculty, students, and staff, plus materials from the uw’s archives and uw’s school of public and community health. in 2008, researchworks was self-archiving. most contributors were expected to use dspace to create and upload their record. there is no indication in the publicly available information about the record creation workflow if record reviews were conducted before record upload. the help link on the researchworks homepage brought contributors to a set of screen-by-screen instructions on how to use dspace’s software to create and upload a record. the step-through did not include instructions on how to edit a record once it had been created. no explanation of the meanings or definitions of the various dc elements was included in the help files. there also were no suggestions about the use of a controlled vocabulary or a thesaurus for subject headings. by 2009, this link had disappeared and the associated contributor education materials with it. the knowledge bank at ohio state university(osu) is the third repository examined for this paper. osu’s repository hosts more than thirty communities, all of which are associated with various academic departments or special university programs. like researchworks at uw, osu’s repository appears to be self-archiving with no clear policy statement as to whether a record is reviewed before it is uploaded to the repository’s database. osu makes a strong effort to educate its contributors. on the upper-left of the knowledge bank homepage is a slider link that brings the contributor (or any user) to several important and useful sources of repository information: about knowledge bank, faqs, policies, video upload procedures, community set-up form, describing your resources, and knowledge bank licensing agreement. the existence and use of metadata in knowledge bank are explicitly mentioned in the faq and policies areas, together with an explanation of what metadata is and how metadata is used (faq), and a list of supported metadata elements (policies). the describe your resources section gives extended definitions of each dspace-available dc metadata element and provides examples of appropriate metadata-element use. knowledge bank provides the most comprehensive contributor education information of any of the three repositories examined. it does not use a controlled vocabulary list for subject headings, and it does not offer a thesaurus. n data and analysis i chose twenty randomly selected full records from each repository. no more than one record was taken from any one collection to gather a broad sampling from each repository. i examined each record for the quality of its metadata. metadata quality is a semantically slippery term. park, in the spring 2009 special metadata issue of cataloging and classification quarterly, suggested that most commonly accepted criteria for metadata quality are completeness, accuracy, and consistence.3 those criteria will be applied in this analysis. for the purpose of this paper, i define completeness as the fill rate for key metadata elements. because the purpose of metadata is to identify the record and to assist in the user’s search process, the key elements are title, contributor/creator, subject, and description.abstract— all contributor-generated fields. i chose these elements because these are the fields that the dspace software uses when someone conducts an unrestricted search. table 1 shows the fill rate for the title element is 100 percent for all three repositories. this is to be expected because, as noted above, title is mandatory field. the fill rate for contributor/creator is likewise high: 16 of 20 (80 percent) for unm, 19 of 20 (95 percent) for uw, and 19 of 20 (95 percent) for osu. (osu’s fill rate for creator and contributor were summed because osu uses different definitions for creator and contributor element fields than do unm or uw. this discrepancy will be discussed in greater depth in the consistency of metadata terminology below.) the fill rate for subject was more variable. unm’s subject fill rate was 100 percent, while uw’s was 55 percent, and osu’s was 40 percent. the fill rate for the description.abstract subfield was 12 of 80 (60 percent) at unm, 15 of 20 (75 percent) at uw, and 8 of 20 (40 percent) at osu. (see appendix a for a complete list of metadata elements and subfields used by each of the three repositories.) the relatively low fill rate (below 50 percent) at the osu knowledgebank in both subject and description .abstract suggests a lack of completeness in that repository’s records. accuracy in metadata quality is the essential “correctness” of a record. correctness issues in a record range from data-entry issues (typos, misspellings, and inconsistent date formats) to the correct application of metadata definitions and data overlaps.4 accuracy is perhaps the most difficult of the metadata 44 information technology and libraries | march 2010 quality criteria to judge. local practices vary widely, and dc allows for the creation of custom metadata tags for local use. additionally, there is long-standing debate and confusion about the definitions of metadata elements even among librarians and information professionals.5 because of this, only the most egregious of accuracy errors were considered for this paper. all three repositories had at least one record that contained one or more inaccurate metadata fields; two of them had four or more inaccurate records. inaccurate records included a wide variety of accuracy errors, including poor subject information (no matter how loosely one defines a subject heading, “the” is not an accurate descriptor); mutually contradictory metadata (record contained two different language tags, although only one applied to the content); and one in which the abstract was significantly longer and only tangentially related than the file it described. additionally, records showed confusion over contributor versus creator elements. in a few records, contributors entered duplicate information into both element fields. this observation supports park and childress’s findings that there is widespread confusion over these elements.6 among the most problematic records in terms of accuracy were those contained in uw’s early buddhist manuscripts project. this collection, which has been removed from public access since the original data was drawn for this paper, contained numerous ambiguous, contradictory, and inaccurate metadata elements.7 while contributor-generated subject headings were specifically not examined for this paper, it must be noted that was a wide variation in the level of detail and vocabulary used to describe records. no community within any of the repositories had specific rules for the generation of keyword descriptors for records, and the lack of guidance shows. consistency can be defined as the homogeneity of formats, definitions, and use of dc elements within the records. this consistency, or uniformity, of data is important because it promotes basic semantic interoperability. consistency both inside the repository itself and with other repositories makes the repository easier to use and provides the user with higher quality information. all three repositories showed 100 percent consistency in dspace-generated elements. dspace’s automated creation of date and format fields provided reliably consistent records in those element fields. dspace’s automatic formatting of personal names in the dc.contributor.author and dc.creator fields also provided excellent internal consistency. however, the metadata elements were much less consistent for contributor-generated information. inconsistency within the subject element is where most problems occurred. personal names used as subject heading and capitalization within subject headings both proved to be particular issues. dspace alphabetizes subject headings according to the first letter of the free text entered in the keyword box. thus the same name entered in different formats (first name first or last name first) generates different subject-heading listings. the same is true for capitalization. any difference in capitalization of any word within the free-text entry generates a separate subject heading. another field where consistency was an issue was dc.description.sponsorship. sponsorship is problem because different communities, even different collections within the same community, use the field to hold different information. some collections used the sponsorship field to hold the name of a thesis or dissertation advisor. some collections used sponsorship to list the funding agency or underwriter for a project being documented inside the record. some collections used sponsorship to acknowledge the donation of the physical materials documented by the record. while all of these are valid uses of the field, they are not the same thing and do not hold the same meaning for the user. the largest consistency issue, however, came from table 1. metadata fields and their frequencies

university repositories | kurtz 45 a comparison of repository policies regarding element use and definition. unaltered dspace software maps contributor-generated information entered into the author textbox during the record-creation process into the dc.contributor.author field. however, osu’s dspace software has been altered so that the dc.contributor .author field does not exist. instead, text entered into the author textbox during the record-creation process maps to dc.creator. although both uses are correct, this choice does create a significant difference in element definitions. osu’s dspace author fields are no longer congruent with other dspace author fields. n conclusions dspace was created as repository management tool. by streamlining the record creation workflow and partially automating the creation of metadata, dspace’s developers hoped to make institutional repositories more useful and functional while time providing an improved experience for both users and contributors. in this, dspace has been partially successful. dspace has made it easier for the “metadata naive” contributor to create records. and, in some ways, dspace has improved the quality of repository metadata. its automatically generated fields ensure better consistency in those elements and subfields. its mandatory fields guarantee 100 percent fill rates in some elements, and this contributes to an increase in metadata completeness. however, dspace still relies heavily on contributorgenerated data to fill most of the dc elements, and it is in these contributor-generated fields that most of the metadata quality issues arise. nonmandatory fields are skipped, leading to incomplete records. data entry errors, a lack of authority control over subject headings, and confusion over element definitions can lead to poor metadata accuracy. a lack of enforced, uniform naming and capitalization conventions leads to metadata inconsistency, as does the localized and individual differences in the application of metadata element definitions. while most of the records examined in this small survey could be characterized as “acceptable” to “good,” some are abysmal. to improve the inconsistency of the dspace records, the three universities have tried differing approaches. only unm’s required record review by a subject area librarian before upload seems to have made any significant impact on metadata quality. unm has a 100 percent fill rate for subject elements in its records, while uw and osu do not. this is not to say that unm’s process is perfect and that poor records do not get into the system—they do (see appendix b for an example). but it appears that for now, the intermediary intervention of a librarian during the record-creation process is an improvement over self-archiving—even with education—by contributors. references and notes 1. association of library collections & technical services, committee on cataloging: description & access,

abstract as libraries begin to embrace web 2.0 technologies to serve patrons, ushering in the era of library 2.0, unique dilemmas arise regarding protection of patron privacy. the norms of web 2.0 promote the open sharing of information—often personal information—and the design of many library 2.0 services capitalize on access to patron information and might require additional tracking, collection, and aggregation of patron activities. thus embracing library 2.0 potentially threatens the traditional ethics of librarianship, where protecting patron privacy and intellectual freedom has been held paramount. as a step towards informing the decisions to implement library 2.0 to adequately protect patron privacy, we must first understand how such concerns are being articulated within the professional discourse surrounding these next generation library tools and services. the study presented in this paper aims to determine whether and how issues of patron privacy are introduced, discussed, and settled, if at all, within trade publications utilized by librarians and related information professionals introduction in today’s information ecosystem, libraries are at a crossroads: several of the services traditionally provided within their walls are increasingly made available online, often by non-traditional sources, both commercial and amateur, thereby threatening the historical role of the library in collecting, filtering, and delivering information. for example, web search engines provide easy access to millions of pages of information, online databases provide convenient gateways to news, images, videos, as well as scholarship, and largescale book digitization projects appear poised to make roaming the stacks seem an antiquated notion. further, the traditional authority and expertise enjoyed by librarians has been challenged by the emergence of automated information filtering and ranking systems, such as google’s algorithms or amazon’s recommendation system, as well as amateur, collaborative, and peerproduced knowledge projects, such as wikipedia, yahoo! answers, and delicious. meanwhile, the professional, educational, and social spheres of our lives are increasingly intermingled through online social networking spaces such as facebook, linkedin, and twitter, providing new interfaces for interacting with friends, collaborating with colleagues, and sharing information. michael zimmer, phd, (zimmerm@uwm.edu), a lita member, is assistant professor, school of information studies, and director, center for information policy research, university of wisconsin-milwaukee. mailto:zimmerm@uwm.edu information technology and libraries | june 2013 30 libraries face a key question in this new information environment: what is the role of the library in providing access to knowledge in today’s digitally networked world? one answer has been to actively incorporate features of the online world into library services, thereby creating “library 2.0.” conceptually, library 2.0 is rooted in the global web 2.0 discussion, and the professional literature often links the two concepts. according to o’reilly, web 2.0 marks the world wide web’s shift from a collection of individual websites to a computing platform that provides applications for end users and can be viewed as a tool for harnessing the collective intelligence of all web users.1 web 2.0 represents a blurring of the boundaries between web users and producers, consumption and participation, authority and amateurism, play and work, data and the network, reality and virtuality.2 its rhetoric suggests that everyone can and should use new internet technologies to organize and share information, to interact within communities, and to express oneself. in short, web 2.0 promises to empower creativity, to democratize media production, and to celebrate the individual while also relishing the power of collaboration and social networks. library 2.0 attempts to bring the ideology of web 2.0 into the sphere of the library. the term is generally attributed to casey,3 and while over sixty-two distinct viewpoints and seven different definitions of library 2.0 have been advanced,4 there is general agreement that implementing library 2.0 technologies and services means bringing interactive, collaborative, and user-centered web-based technologies to library services and collections.5 examples include • providing synchronous messaging (through instant message platforms, skype, etc.) to allow patrons to chat with library staff for real-time assistance; • using blogs, wikis, and related user-centered platforms to encourage communication and interaction between library staff and patrons; • allowing users to create personalized subject headings for library materials through social tagging platforms like delicious or goodreads; • providing patrons the ability to evaluate and comment on particular items in a library’s collection through rating systems, discussion forums, or comment threads; • using social networking platforms like facebook or linkedin to create online connections to patrons, enabling communication and service delivery online; and • creating dynamic and personalized recommendation systems (“other patrons who checked out this book also borrowed these items”), similar to amazon and related online services. launching such library 2.0 features, however, poses a unique dilemma in the realm of information ethics, especially patron privacy. traditionally, the context of the library brings with it specific norms of information flow regarding patron activity, including a professional commitment to patron privacy (see, for example, american library association’s privacy policy, 6 foerstel,7 gorman,8 and morgan 9). in the library, users’ intellectual activities are protected by decades of established norms and practices intended to preserve patron privacy and confidentiality, most assessing the treatment of patron privacy in library 2.0 literature | zimmer 31 stemming from the ala’s library bill of rights and related interpretations.10 as a matter of professional ethics, most libraries protect patron privacy by engaging in limited tracking of user activities, having short-term data retention policies (many libraries actually delete the record that a patron ever borrowed a book once it is returned), and generally enable the anonymous browsing of materials (you can walk into a public library, read all day, and walk out, and there is no systematic method of tracking who you are or what you’ve read). these are the existing privacy norms within the library context. library 2.0 threatens to disrupt these norms. in order to take full advantage of web 2.0 platforms and technologies to deliver library 2.0 services, libraries will need to capture and retain personal information from their patrons. revisiting the examples provided above, each relies on some combination of robust user accounts, personal profiles, and access to flows of patrons’ personal information: • providing synchronous messaging might necessitate the logging of a patron's name (or chat username), date and time of the request, e-mail or other contact information, and the content of the exchange with the librarian staff member. • library-hosted blogs or wikis will require patrons to create user accounts, potentially tying posts and comments to patron ip addresses, library accounts, or identities. • implementing social tagging platforms would similarly require unique user accounts, possibly revealing the tags particular patrons use to label items in the collection and who tagged them. • comment and rating systems potentially link patrons’ particular interests, likes, and dislikes to a username and account. • using social networking platforms to communicate and provide services to patrons might result in the library gaining unwanted access to personal information of patrons, including political ideology, sexual orientation, or related sensitive information. • creating dynamic and personalized recommendation systems requires the wholesale tracking, collecting, aggregating, and processing of patron borrowing histories and related activities. across these examples, to participate and benefit from library 2.0 services, library patrons could potentially be required to create user accounts, engage in activities that divulge personal interests and intellectual activities, be subject to tracking and logging of library activities, and risk having various activities and personal details linked to their library patron account. while such library 2.0 tools and services can greatly improve the delivery of library services and enhance patron activities, the increased need for the tracking, collecting, and retaining of data about patron activities presents a challenge to the traditional librarian ethic regarding patron privacy.11 despite these concerns, many librarians recognize the need to pursue library 2.0 initiatives as the best way to serve the changing needs of their patrons and to ensure the library’s continued role in information technology and libraries | june 2013 32 providing professionally guided access to knowledge. longitudinal studies of library adoption of web 2.0 technologies reveal a marked increase in the use of blogs, sharing plugins, and social media between 2008 and 2010.12 in this short amount of time, library 2.0 has taken hold in hundreds of libraries, and the question before us is not whether libraries will move towards library 2.0 services, but how they will do it, and, from an ethical perspective, whether the successful implementation of library 2.0 can take place without threatening the longstanding professional concerns for, and protections of, patron privacy. research questions recognizing that library 2.0 has been implemented, in varying degrees, in hundreds of libraries,13 and is almost certainly being considered at countless more, it is vital to ensure that potential impacts on patron privacy are properly understood and considered. as a step towards informing the decisions to implement library 2.0 to adequately protect patron privacy, we must first understand how such concerns are being articulated within the professional discourse surrounding these next generation library tools and services. the study presented in this paper aims to determine whether and how issues of patron privacy are introduced, discussed, and settled—if at all—within trade publications utilized by librarians and related information professionals. specifically, this study asks the following primary research questions: rq1. are issues of patron privacy recognized and addressed in literature discussing the implementation of library 2.0 services? rq2. when patron privacy is recognized and addressed, how is it articulated? for example, is privacy viewed as a critical concern, as something that we will need to simply “get over,” or as a non-issue? rq3. what kind of mitigation strategies, if any, are presented to address the privacy issues related to library 2.0? data analysis the study combines content and textual analyses of articles published in professional publications (not peer-reviewed academic journals) between 2005 and 2011 discussing library 2.0 or related web-based services, retrieved through the library, information science, and technology abstracts (lista) and library literature & information science full text databases. the discovered texts were collected in winter 2011 and coded to reflect the source, author, publication metadata, audience, and other general descriptive data. in total, there were 677 articles identified discussing library 2.0 and related web-based library services, appearing in over 150 different publications. of the articles identified, 50 percent of appeared in 18 different publications, which are listed in table 1. assessing the

identification of variations in terminology. for example, each text was searched for the fragment “priv” to include hits on both the terms “privacy” and “private.” additional searchers were performed for word fragments related to “intellectual freedom” and “confidentiality” in order to capture more general considerations related to patron privacy. of the 677 articles discussing library 2.0 and related web-based services, there were a total of 203 mentions of privacy or related concepts in 71 articles. these 71 articles were further refined to ensure the appearance of the word “privacy” and related terms were indeed relevant to the ethical issues at hand (eliminating false positives for mentions of “private university,” for example, or mention of a publication’s “privacy policy” that happened to be provided in the pdf searched). the final analysis yielded a total of 39 articles with relevant mention of patron privacy as it relates to library 2.0, amounting to only 5.8 percent of all articles discussing library 2.0 (see table 2). a full listing of the articles is in appendix a. information technology and libraries | june 2013 34 table 2. article summary count % total articles discussing library 2.0 articles with hit in “priv” and related text searches articles with relevant discussion of privacy 677 71 39 10.5 5.8 the majority of these articles were authored by practicing librarians in both public and academic settings and present arguments for the increased use of web 2.0 by libraries or highlight successful deployment of library 2.0 services. of the 39 articles, only 4 focus primarily on challenges faced by libraries hoping to implement library 2.0 solutions.14 a textual analysis of the 39 relevant articles was performed to assess how privacy was discussed in each. two primary variables were evaluated: the length of discussion, and the level of concern. length of discussion was measured qualitatively as high (concern over privacy is explicit or implicit in over 50 percent of the article’s text), moderate (privacy is discussed in a substantive section of the article), and minimal (privacy is mentioned, but not given significant attention). the level of concern was measured qualitatively as high (indicated privacy as a critical variable for implementing library 2.0), moderate (recognized privacy as one of a set of important concerns), and minimal (mentioned privacy largely in passing, giving it no particular importance). results of these analyses are reported in table 3. table 3. length of discussion and level of concern length of discussion level of concern high moderate minimal 3 8 28 9 13 16 of the 39 relevant articles, only three had lengthy discussions of privacy-related issues. as early as 2007, coombs recognized that the potential for personalization of library services would force libraries to confront existing policies regarding patron privacy. 15 anderson and rethlefsen similarly engage in lengthy discussions of the challenges faced by libraries wishing to balance patron privacy with new web 2.0 tools and services. 16 these three articles represent less than 1 percent of the 677 total articles identified that discussed library 2.0 while only three articles dedicate lengthy discussions to issues of privacy, over half the articles that mention privacy (21 of 39) indicate a high or moderate level of concern. for example, cvetkovic warns that while “privacy is a central, core value of libraries…the features of web 2.0 applications that make them so useful and fun all depend on users sharing private information with the site owners.” 17 and casey and savastinuk’s early discussion of library 2.0 puts these concerns in context for librarians, warning that “libraries should remain as vigilant with assessing the treatment of patron privacy in library 2.0 literature | zimmer 35 protecting customer privacy with technology-based services as they are with traditional, physical library services.” 18 while 21 articles indicated a high or moderate level of concern over patron privacy, less than half of these provided any kind of solution or strategy for mitigating the privacy concerns related to implementing library 2.0 technologies. overall, 14 of the 39 relevant articles provided privacy solutions of one kind or another. breeding, for example, argues that librarians must “absolutely respect patron privacy,” 19 and suggests any library 2.0 tools that rely on user data should only be implemented if users must explicitly “opt-in” to having their information collected, a solution also offered by wisniewski in relation to protecting patron privacy with location-based tools.20 rethlefsen goes a step further, proposing libraries take steps to increase the literacy of patrons regarding their privacy and the use of library 2.0 tools, including the use of classes and tutorials to help educate patrons and staff alike. 21 conversely, cvetkovic argues that “the place of privacy in our culture is changing,” and that while “in many ways our privacy is diminishing, but many people…seem not too concerned about it.” 22 as a result, while she argues for only voluntary participation in library 2.0 services, cvetkovic takes a position that information sharing is becoming the new norm, weakening any absolute position regarding protecting patron privacy above all. discussion rq1 asks if issues of patron privacy are recognized and addressed within literature discussing library 2.0 and related web-based library services. of the 677 articles published for professional audiences that discuss library 2.0, only 39 contained a relevant discussion of the privacy issues that stem from this new family of data-intensive technologies, and only 11 of these discussed the issue beyond a passing mention. rq2 asks how the privacy concerns, when present, are articulated. of the 39 articles with relevant discussions of privacy, only 11 make more than a minimal mention of privacy concerns. however, the discussion in 22 of the articles reveals a high or moderate level of concern. this suggests that while privacy might not be a primary focus of discussion, when it is mentioned, even minimally, its importance is recognized. finally, rq3 seeks to understand if any solutions or mitigation strategies related to the privacy concerns are articulated. with only 14 of the 39 articles providing a means for practitioners to address privacy issues, readers of library 2.0 publications are more often than not left with no real solutions or roadmaps for dealing with these vital ethical issues. taken together, the results of this study reveal minimal mention of privacy alongside discussions of library 2.0. less than 6 percent of all 677 articles on library 2.0 include mention of privacy; of these, only 11 make more than a passing mention of privacy, representing less than 2 percent of information technology and libraries | june 2013 36 all articles. of the 39 relevant articles, 22 express more than a minimal concern, but of these, only 9 provide any mitigation strategy. these results suggest that while popular publications targeted at information professionals are giving significant attention to potential for library 2.0 to be a powerful new option for delivering library content and services, there is minimal discussion of how the widespread adoption and implementation of these new tools might impact patron privacy and even less discussion of how to address these concerns. consequently, as the interest in, and adoption of, library 2.0 services increase, librarians and related information practitioners seeking information regarding these new technologies in professional publications will not likely be confronted with the possible privacy concerns, nor learn of any strategies to deal with them. this absence of clear guidance for addressing patron privacy in the library 2.0 era resembles what computer ethicist jim moor would describe as a “policy vacuum”: a typical problem in computer ethics arises because there is a policy vacuum about how computer technology should be used. computers provide us with new capabilities and these in turn give us new choices for action. often, either no policies for conduct in these situations exist or existing policies seem inadequate. a central task of computer ethics is to determine what we should do in such cases, that is, formulate policies to guide our actions. 23 given the potential for the data-intensive nature of library 2.0 technologies to threaten the longstanding commitment to patron privacy, these results show that work must be done to help fill this vacuum. education and outreach must be increased to ensure librarians and information professionals are aware of the privacy issues that typically accompany attempts to implement library 2.0, and additional scholarship must take place to help understand the true nature of any privacy threats and to come up with real and useful solutions to help find the proper balance between enhanced delivery of library services through web 2.0-based tools and the traditional protection of patron privacy. acknowledgements this

information technology and libraries | june 2014 45 abstract open search systems present a free and less restricted alternative to commercial search services. this paper explores the space of open search technology, looking in particular at lightweight search protocols and the issue of interoperability. a description of current protocols and formats for engineering open search applications is presented. the suitability of these technologies and issues around their adoption and operation are discussed. this open search approach is especially useful in applications involving the harvesting of resources and information integration. principal among the technological solutions are opensearch, sru, and oai-pmh. opensearch and sru realize a federated model to enable content providers and search clients communicate. applications that use opensearch and sru are presented. connections are made with other pertinent technologies such as open-source search software and linking and syndication protocols. the deployment of these freely licensed open standards in web and digital library applications is now a genuine alternative to commercial and proprietary systems. introduction web search has become a prominent part of the internet experience for millions of users. companies such as google and microsoft offer comprehensive search services to users free with advertisements and sponsored links, the only reminder that these are commercial enterprises. businesses and developers on the other hand are restricted in how they can use these search services to add search capabilities to their own websites or for developing applications with a search feature. the closed nature of the leading web search technology places barriers in the way of developers who want to incorporate search functionality into applications. for example, google’s programmatic search api is a restful method called google custom search api that offers only 100 search queries per day for free.1 the limited usage restrictions of these apis mean that organizations are now frequently looking elsewhere for the provision of search functionality. free software libraries for information retrieval and search engines have been available for some time allowing developers to build their own search solutions. these libraries enable search and retrieval of document collections on the web or offline. web crawlers can harvest content from multiple sources. a problem is how to meet users’ expectations of search efficacy while not having adrian o’riordan (a.oriordan@cs.ucc.ie) is lecturer, school of computer science and information technology, university college, cork, ireland. open search environments: the free alternative to commercial search services | o’riordan 46 the resources of the large search providers. reservations about the business case for free open search include that large-scale search is too resource-hungry and the operational costs are too high; but these suppositions have been challenged.2 open search technology enables you to harvest resources and combine searchers in innovative ways outside the commercial search platforms. further prospects for open search systems and open-source search lie in areas such as peer-to-peer, information extraction, and subject-specific technology.3 many search systems unfortunately use their own formats and protocols for indexing, search, and results lists. this makes it difficult to extend, alter, or combine services. distributed search is the main alternative to building a “single” giant index (on mirrored clusters) and searching at one site, a la google search and microsoft bing. callan describes the distributed search model in an information retrieval context.4 in his model, information retrieval consists of four steps: discovering databases, ranking databases by their expected ability to satisfy the query, searching the most relevant databases, and merging results returned by the different databases. distributed search has become a popular approach in the digital libraries field. note that in the digital libraries literature distributed search is often called federated search.5 the federated model has clear advantages in some application areas. it is very hard for a single index to do justice to all the possible schemas in use on the web today. other potential benefits can come from standardization. the leading search engine providers utilize their own proprietary technologies for crawling, indexing, and the presentation of results. the standardization of result lists would be useful for developers combining information from multiple sources or pipelining search to other functions. a common protocol for declaring and finding searchable information is another desirable feature. standardized formats and metadata are key aspects of search interoperability, but the focus of this article is on protocols for exchanging, searching, and harvesting information. in particular, this article focuses on lightweight protocols, often rest (representational state transfer)–style applications. lightweight protocols place less onerous overheads on development in terms of adapting existing systems and additional metadata. they are also simpler. the alternative is heavyweight approaches to federated search, such as using web services or service-oriented architectures. there have been significant efforts at developing lightweight protocols for search, primary among which is the opensearch protocol developed by an amazon subsidiary. other protocols and services of relevance are sru, mxg, and the oai-omh interoperability framework. we describe these technologies and give examples of their use. technologies for the exchange and syndication of content are often used as part of the search process or in addition. we highlight key differences between protocols and give instances where technologies can be used in tandem. information technology and libraries | june 2014 47 this paper is structured as follows. the next section describes the open search environment and the technologies contained therein. the following section describes open search protocols in detail, giving examples. finally, summary conclusions are presented. an open search environment a search environment (or ecosystem) consists of a software infrastructure and participants. the users of search services and the content providers and publishers are the main participants. the systems infrastructure consists of the websites and applications that both publish resources and present a search interface for the user, and the technologies that enable search. technologies include publishing standards for archiving and syndicating content, the search engines and web crawlers, the search interface (and query languages), and the protocols or glue for interoperability. baeza-yates and raghavan present their vision of next-generation web search highlighting how developments in the web environment and search technology are shaping the next generation search environment.6 open-source libraries for the indexing and retrieval of document collections and the creation of search engines include the lemur project (and the companion indri search engine),7 xapian,8 sphinx,9 and lucene (and the associated nutch web crawler).10 all of these systems support web information retrieval and common formats. from a developer perspective they are all crossplatform; lemur/indri, xapian, and sphinx are in c and c++ whereas lucene/nutch is in java. xapian has language bindings for other programming languages such as python. the robustness and scalability of these libraries support large-scale deployment, for example the following large websites use xapian: citebase, die zeit (german newspaper), and debian (linux distribution).11 middleton and baeza-yates present a more detailed comparison of open-source search engines.12 they compare twelve open-source search engines including indri and lucene mentioned above across thirteen dimensions. features include license, storage, indexing, query preprocessing (stemming, stop-word removal), results format, and ranking. apache solr is a popular open-source search platform that additionally supports features such as database integration, real-time indexing, faceted search, and clustering.13 solr uses the lucene search library for the core information retrieval. solr’s rich functionality and the provision of restful http/xml and json apis makes it an attractive option for open information integration projects. in a libraries context singer cites solr as an open-source alternative for next-generation opac replacements.14 solr is employed, for example, in the large-scale europeana project.15 the focus of much of this paper is on the lightweight open protocols and interoperability solutions that allow application developers to harvest and search content across a range of locations and formats. in contrast, the delosdlms digital library framework exemplifies a heavyweight approach to integation.16 in delosdlms, services are either loosely or tightly coupled in a serviceoriented architecture using web service middleware. open search environments: the free alternative to commercial search services | o’riordan 48 particular issues for open search are the location and collection of metadata for searchable resources and the creation of applications offering search functionality. principal among these technological solutions are the opensearch and sru protocols. both implement what alipourhafezi et al. term a federated model in the context of search interoperability, wherein providers agree that their services will conform to certain standard specifications.17 the costs and adoption risk of this approach are low. technologies such as opensearch occupy an abstraction layer above existing search infrastructure such as solr. interoperability interoperability is an active area of work in both the search and digital library fields. interoperability is “the ability of two or more systems or components to exchange information and to use the information that has been exchanged.”18 interoperability in web search applies to resource harvesting, meta-search, and to allow search functions interact with other system elements. interoperability in digital libraries is a well-established research agenda,19 and it has been described by paepcke et al. as “one of the most important problems to solve [in dls].”20 issues that are common to both web search and digital-library search include metadata incompatibilities, protocol incompatibilities, and record duplication and near-duplication. in this paper, the focus is on search protocols; for a comprehensive survey of technology for semantic interoperability in digital library systems, see the delos report on same.21 a comprehensive survey of methods and technology for digital library interoperability is provided in a dl.org report.22 formats and metadata free and open standard formats are extensive in web technology. standard or de facto formats for archiving content include plain text, rich text format (rtf), html, pdf, and various xml formats. document or resource identification is another area where there has been much agreement. resource identification schemes need to be globally unique, persistent, efficient, and extensible. popular schemes include urls, persistent urls (purls), the handle system (handle.net), and dois (digital object identifiers). linking technologies include openurl and coins. openurl links sources to targets using a knowledge base of electronic resources such as digital libraries.23 contextobjects in spans (coins), as used in wikipedia for example, is another popular linking technology.24 applications can use various formats for transporting and syndicating content. syndication and transport technologies include xml, json, rss/atom, and heavyweight web service-based approaches. much of the metadata employed in digital libraries is in xml formats, for example in marcxml and the metadata encoding and transmission standard (mets). the world wide web consortium defined rdf (resource description framework) to provide among other goals “a mechanism for integrating multiple metadata schemes.”25 rdf records are defined in an xml namespace. in rdf, subject-predicate-object expressions represent web information technology and libraries | june 2014 49 resources and typically identified by means of an uri (universal resource identifier). json (javascript object notation) is a lightweight data-interchange format that has become popular in web-based applications and is seeing increasing support in digital library systems.26 harvesting web content is harvested using software called web crawlers (or web spiders). a crawler is an instance of a software application that runs automated tasks on the web. specifically the crawler follows web links to index websites. there was been little standardization in this area except the robot exclusion standard and use of various xhtml meta-elements and http header fields. there is a lot of variability in terms of the policy for the selection of content sources, policy for following links, url normalization, politeness, depth of crawl, and revisit policy. consequently, there are many web crawling systems in operation; open-source crawlers include datapartsearch, grub, heritrix, and the aforementioned nutch. harvesting and syndication of metadata from open repositories is the goal of the open archives initiative protocol for metadata harvesting (oai-pmh), originally developed by los alamos national laboratory, cornel, and nasa in 2000 and 2001.27 resource harvesting challenges include scale, keeping information up-to-date, robustness, and security. oai-pmh has been adopted by many digital libraries, museums, archives, and publishers. the latest version, oai-pmh 2.0, was released in 2012. oai-pmh specifies a general application-independent model of network-accessible repository and client harvester that issues requests using http (either get or post). metadata is expressed as a record in xml format. an oai-phm implementation must support dublin core, with other vocabularies as additions. oai-pmh is the key technology in the harvesting model of digital library interoperability described by van de sompel et al.28 an oai-pmh-compliant system consists of harvester (client), repository (network accessible server), and items (constituents of a repository). portal sites such as europeana and oaister use oai-pmh to harvest from large numbers of collections.29 there are online registries of oai-compliant repositories. the european commission’s europeana allow users to search across multiple image collections including the british library and the louvre online. another portal site that uses oai-pmh is culturegrid, operated by the uk collections trust. culturegrid provides access to hundreds of museum, galleries, libraries, and archives in the uk. the apache software foundation has developed a module, mod_oai, for apache webservers that helps crawlers to discover content. syndication and exchange here we outline lightweight options for syndication and information exchange. heavyweight web services-based approaches are outside the scope of this article. web syndication commonly uses rss (really simple syndication) or its main alternative, atom. atom is a proposed ietf standard.30 rss 2.0 is the latest version in the rss family of specifications, a simple yet highly extensible open search environments: the free alternative to commercial search services | o’riordan 50 format where content items contain plain text or escaped html.31 atom, developed to counter perceived deficiencies in rss, has a richer content model than rss and is more reusable in other xml vocabularies.32 both rss and atom use http for transport. rss organizes information into channels and items, atom into feeds and entries. extension as modules allows rss to carry multimedia payload (rss enclosures) and geographical information (georss). atom has an associated publishing protocol called atompub. syndication middleware, which supports multiple formats, can serve as an intermediary in application architectures. information and content exchange (ice) is a protocol that aims to “automate the scheduled, reliable, secure redistribution of any content.”33 twice is a java implementation of ice. ice automates the establishment of syndication relationships and handles data transfer and results formatting. this gives content providers more control over delivery, schedule, and reliability than simple web syndication without deploying a full-scale web services solution. the open archives initiative—object reuse and exchange (oai-ore) protocol provides standards for the description and exchange of aggregations of web resources.34 this specification standardizes how compound digital objects can combine distributed resources of multiple media types. ore introduces the concepts of aggregation, resource map, and proxy resource. resource providers or curators can express objects in rdf or atom format and assign http uris for identification. ore supports resource discovery so crawlers or harvesters can find these resource maps and aggregates. ore can work in partnership with oai-pmh. we outline some additional lightweight technologies for information exchange to conclude this section. opml (outline processor markup language) is a format that represents lists of web feeds for services such as aggregators.35 it is a simple xml format. feedsync and rome support formatneutral feed formats that abstract from wire formats such as rss 2.0 and atom 1.0 for aggregator or syndication middleware. these technologies are described in the literature.36 lockss (lots of copies keep stuff safe) is a novel project that users a peer-to-peer network to preserve and provide access to web resources. for example, the metaarchive cooperative uses lockss for digital preservation.37 meta-search meta-search is where multiple search services are combined. such services have a very small share of the total search market owing to the dominance of the big players. metacrawler, developed in the 1990s, was one of the first meta-search engines and serves as a model for how such systems operate.38 a meta-search engine utilizes multiple search engines by sending a user request to multiple sources or engines aiming to improve recall in the process. a key issue with meta-search is how to weight search engines and how to integrate sets of results into a single results list. figure 1 shows a general model of meta-search where the meta-search service chooses which search engines and content providers to employ. active meta-search engines on the web include dogpile, yippy, ixquick, and info.com. note that these types of website appear, change information technology and libraries | june 2014 51 names, and disappear frequently. currently meta-search services use various implementation methods such as proprietary protocols and screen scraping. figure 1. general model of meta-search. metasearch xml gateway (mxg) is a meta-search protocol developed by the niso metasearch initiative, a consortium of meta-search developers and interested parties.39 mxg is a message and response protocol, which enables meta-search service providers and content providers communicate. a goal of the design of mxg was that content providers should not have to expend substantial development resources. mxg, based on sru, specifies both the query and search results formats. combining results, aggregation and presentation are not part of the protocol and handled by the meta-search service. the standard defines three levels of compliance allowing varying degrees of commitment and interoperability. search protocols we describe opensearch and sru, along with applications, in the following subsections. after that, we detail related technologies. opensearch opensearch is a protocol that defines simple formats to help search engines and content providers communicate. it was developed by a9, a subsidiary of amazon, in 2005.40 it defines common formats for describing a search service, query results, and operation control. it does not specify content formats for documents or queries. the current specification, version 1.1, is available with a creative commons license. it is an extensible specification with extensions published on the website. both free open systems and proprietary systems use opensearch. in particular, many open-source search engines and content management systems support opensearch, including yacy, drupal and plone cms. opensearch consists of a description file for search source and a response format for query results. descriptors include elements url, query, syndicationright, and language. resource identification can be by urls, dois, or a linking technology such as openurl. responses describe a list of results and can be in rss, atom, or html formats. additionally there is an auto-discovery feature to signal that a html page is searchable, implemented using a html 4.0 <link> element. search engine content provider search engine content provider choose combine query combined results open search environments: the free alternative to commercial search services | o’riordan 52 opensearch makes very few assumptions about the types of sources, the type of query or the search operation. it is ideal for combining content from multiple disparate sources, which may be data from repositories, webpages, or syndicated feeds. for illustrative purposes, listing 1 gives an example opensearch description for harvesting book information from an example digital library called diglib. the root node <openseachdescription> includes an xml namespace attribute, which gives the url for the standard version. the url element specifies the content type (a mime type), the query (book in this case), and the index offset where to begin. the rel attribute states that the result is a collection of resources. <openseachdescription xmlns=http://a9.com/~/spec/opensearch/1.1/> <shortname>diglib</shortname> <description>harvests book items</description> <url type="application/rdf+xml" indexoffset="0" rel="collection" template="http://diglib.com/?q={book}&amp;start={startindex?}&amp;format=rdf" /> <language>en-us</language> <outputencoding>utf-8</outputencoding> </opensearchdescription> listing 1. xml opensearch description record. next, we describe some deployed applications that use opensearch. ojax uses qeb technologies such as ajax (asynchronous javascript) to provide a federated search service for oai-pmh compatible open repositories.41, 42 ojax also supports the discovery feature of opensearch, as described in the opensearch 1.1 specification, for auto-detecting that a repository is searchable. stored searches are in atom format. open-source meta-search engines can combine the results of opensearch enabled search engines.43 a system built as a proof-of-concept uses four search sources: a9.com, yacy, mozdex, and alpha. a user can issue a text query (word or phrase) with boolean operators and several modifiers. users can prefer or bias particular engines by setting weights. the system ranks results, combined using a voting algorithm and implemented using the lucene library. opensearch can be employed to specify the search sources and as a common format when results are combined. as levan points out “the job of the meta-search engine is made much simpler if the local search engine supports a standard search interface.”44 levan also mentions mxg in this context. nguyen et al. describe an application where over one hundred search engines are used in experiments in federated search.45 the search sources were mostly opensearch-compliant search engines. an additional tool scrapes results from noncompliant systems. intersynd uses opensearch to help provide a common protocol for harvesting web feeds. intersynd is a syndication system that harvests, stores, and provides feed recommendations.36 it uses java.net’s rome (rss and atom utilities) library to represent feeds in a format-neutral way. information technology and libraries | june 2014 53 intersynd is syndication middleware that allows sources to post and services to fetch information in all major syndication formats (see figure 2). its feed-discovery module, disco, uses the nutch crawler and the opensearch protocol to harvest feeds. nutch is an open-source library for building search engines that supports opensearch. nutch builds on the lucene information retrieval library, adding web-specifics, such as a crawler, a link-graph database, and parsers for html. figure 2. openseach in intersynd. opensearch 1.1 allows returned results in either rss 2.0 or atom 1.0 format or an opensearch format, the “bare minimum of additional functionality required to provide search results over rss channels” (quoted from a9 website). listing 2 below shows a disco results list in rss 2.0 format. opensearch fields appear in the channel description. the nutch fields appear within each item (not shown). an opensearch namespace is specified in the opening <rss> xml element. the following additional opensearch elements appear in the example: totalresults, itemsperpage and startindex. <?xml version="1.0" encoding="utf-8"?> <rss version="2.0" xmlns:nutch="http://www.nutch.org/opensearchrss/1.0/" xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/"> <channel> <title>nutch:

listing 2. results produced using nutch with opensearch. open search environments: the free alternative to commercial search services | o’riordan 54 we mention one more application of opensearch here. a series of nasa projects to develop a set of interoperable standards for sharing information employs various open technologies for sharing and disseminating datasets including opensearch for its discovery capability.46 discovery of document and data collections is by keyword search, using the opensearch protocol. there are various extensions to opensearch. for example, an extension to handle sru allows sru (search and retrieval via url) queries within opensearch contexts. other proposed extensions include support for mobility, e-commerce, and geo-location. sru (search/retrieval via url) a technology with some similarities to opensearch but more comprehensive is sru (search/retrieval via url).47 sru is an open restful technology for web search. the current version is sru 2.0, standardized by the organization for the advancement of structured information standards (oasis) as searchretrieve. version 1.0. sru was developed to provide functionality similar to the widely deployed z39.50 standard for library information retrieval updated for the web age.48 sru addresses aspect of search and retrieval by defining models: a data model, a query model, and processing model, a result set model, a diagnostics model and a description-and-discovery model. sru is extensible and can support various underlying low-level technologies. both lucene and dspace implementations are available. the oclc implementation of sru supports both rss and atom feed formats and the atom publishing protocol. sru uses http as the application transport and xml formats for messages. requests can be in the form of either get or post http methods. sru supports a high-level query language called contextual query language (cql). cql is a human-readable query language consisting of search clauses. sru operation involves three parts: explain, search/retrieve and scan. explain is a way to publish resource descriptions. search/retrieve entails the sending of requests (formulated in cql) and the receiving of responses over http. the optional sru scan enables software to query the index. the result list is in xml schema format. the meta-search service mxg uses sru, but relaxes the requirement to use cql.39 srw (search/retrieve web service) is a web services implementation of sru that uses soap as the transfer mechanism. hammond combines opensearch with sru technology in an application for nature publishers.49 he also points out the main differences between the protocols such as sru’s use of a query specification language and differences in the results records. as well as supporting opensearch data formats (rss and atom), the nature application also supports json (javascript object notation). opensearch is used for formatting the result sets whereas sru/cql is used for querying. this search application launched as a public service in 2009. listing 3 below is an example from the nature application showing cql search queries (<query> tags) used in an opensearch description document. note how both the sru querytype and the information technology and libraries | june 2014 55 opensearch searchterms attributes appear in the query. further details on how to use sru and opensearch together are on the opensearch website. <?xml version="1.0" encoding="utf-8"?> <opensearchdescription xmlns="http://a9.com/-/spec/opensearch/1.1/"

</opensearchdescription> listing 3. example using sru and opensearch. other technologies here we more briefly survey some additional technologies of relevance to open-search interoperability. xml-based approaches to information integration, such as the use of xquery, are an option but do not present a loose integration. chudnov et al. describes a simple api for a copy function for web applications to enable syndication, searching, and linking of web resources.50 called unapi, it requires small changes for publishers to add the functionality to web resources such as repositories and feeds. developers can layer unapi over sru, opensearch, or openurl.51 announced in 2008, yahoo!’s searchmonkey technology, also called yahoo!’s open search platform, allowed publishers to add structured metadata to yahoo! search results. searchmonkey divided the problem into two parts: metadata extraction and result presentation. in is not clear how much of this technology survived yahoo! and microsoft’s new search alliance, signed in 2010.52 mika described a search interface technology called microsearch that is similar in nature.53 in microsearch, semantic fields are added a search and search result presentation enriched with open search environments: the free alternative to commercial search services | o’riordan 56 metadata extracted from retrieved content. govaerts et al. described a federated search and recommender system that operates as a browser add-on. the system is opensearch-compliant and all results are in the atom format.54 the corporation for national research initiatives (cnri) digital object architecture (doa) provides a framework for managing digital objects in a networked environment. it consists of three parts: a digital object repository, a resolution mechanism (handle system), and a digital object registry. the repository access protocol (rap) proves a means of networked access to digital objects, which supports authentication and encryption.55 summary and conclusions a rich set of formats and protocols and working implementations show that open search technology is an alternative to the dominant commercial search services. in particular, we discussed the lightweight opensearch and sru protocols as suitable glue to create loosely coupled search-based applications. these can complement other developments in resource discovery and description, open repositories, and open-source information retrieval. the flexibility and extensibility offers exciting opportunities to develop new applications and new types of applications. the successful deployment of open search technology shows that this technology has matured to support many uses. a fruitful area of further development would be to make working with these standards easier for developers and even accessible to the nonprogrammer. references 1. google custom search api, https://developers.google.com/custom-search/v1/overview. 2. mike cafarella and

http://dorepository.org/documentation/protocol_specification.pdf the next generation library catalog | zhou 151are your digital documents web friendly? | zhou 151 are your digital documents web friendly?: making scanned documents web accessible the internet has greatly changed how library users search and use library resources. many of them prefer resources available in electronic format over traditional print materials. while many documents are now born digital, many more are only accessible in print and need to be digitized. this paper focuses on how the colorado state university libraries creates and optimizes text-based and digitized pdf documents for easy access, downloading, and printing. t o digitize print materials, we normally scan originals, save them in archival digital formats, and then make them webaccessible. there are two types of print documents, graphic-based and text-based. if we apply the same techniques to digitize these two different types of materials, the documents produced will not be web-friendly. graphic-based materials include archival resources such as historical photographs, drawings, manuscripts, maps, slides, and posters. we normally scan them in color at a very high resolution to capture and present a reproduction that is as faithful to the original as possible. then we save the scanned images in tiff (tagged image file format) for archival purposes and convert the tiffs to jpeg (joint photographic experts group) 2000 or jpeg for web access. however, the same practice is not suitable for modern text-based documents, such as reports, journal articles, meeting minutes, and theses and dissertations. many old text-based documents (e.g., aged newspapers and books), should be yongli zhoututorial files for fast web delivery as access files. for text-based files, access files normally are pdfs that are converted from scanned images. “bcr’s cdp digital imaging best practices version 2.0” says that the master image should be the highest quality you can afford, it should not be edited or processed for any specific output, and it should be uncompressed.1 this statement applies to archival images, such as photographs, manuscripts, and other image-based materials. if we adopt the same approach for modern text documents, the result may be problematic. pdfs that are created from such master files may have the following drawbacks: ■■ because of their large file size, they require a long download time or cannot be downloaded because of a timeout error. ■■ they may crash a user’s computer because they use more memory while viewing. ■■ they sometimes cannot be printed because of insufficient printer memory. ■■ poor print and on-screen viewing qualities can be caused by background noise and bleedthrough of text. background noise can be caused by stains, highlighter marks made by users, and yellowed paper from aged documents. ■■ the ocr process sometimes does not work for high-resolution images. ■■ content creators need to spend more time scanning images at a high resolution and converting them to pdf documents. web-friendly files should be small, accessible by most users, full-text searchable, and have good treated as graphic-based material. these documents often have faded text, unusual fonts, stains, and colored background. if they are scanned using the same practice as modern text documents, the document created can be unreadable and contain incorrect information. this topic is covered in the section “full-text searchable pdfs and troubleshooting ocr errors.” currently, pdf is the file format used for most digitized text documents. while pdfs that are created from high-resolution color images may be of excellent quality, they can have many drawbacks. for example, a multipage pdf may have a large file size, which increases download time and the memory required while viewing. sometimes the download takes so long it fails because a time-out error occurs. printers may have insufficient memory to print large documents. in addition, the optical character recognition (ocr) process is not accurate for high resolution images in either color or grayscale. as we know, users want the ability to easily download, view, print, and search online textual documents. all of the drawbacks created by high-quality scanning defeat one of the most important purposes of digitizing text-based documents: making them accessible to more users. this paper addresses how colorado state university libraries (csul) manages these problems and others as staff create web-friendly digitized textual documents. topics include scanning, long-time archiving, full-text searchable pdfs and troubleshooting ocr problems, and optimizing pdf files for web delivery. preservation master files and access files for digitization projects, we normally refer to images in uncompressed tiff format as master files and compressed yongli zhou is digital repositories librarian, colorado state university libraries, colorado state university, fort collins, colorado 152 information technology and libraries | september 2010152 information technology and libraries | september 2010 factors that determine pdf file size. color images typically generate the largest pdfs and black-and-white images generate the smallest pdfs. interestingly, an image of smaller file size does not necessarily generate a smaller pdf. table 1 shows how file format and color mode affect pdf file size. the source file is a page containing black-and-white text and line art drawings. its physical dimensions are 8.047" by 10.893". all images were scanned at 300 dpi. csul uses adobe acrobat professional to create pdfs from scanned images. the current version we use is adobe acrobat 9 professional, but most of its features listed in this paper are available for other acrobat versions. when acrobat converts tiff images to a pdf, it compresses images. therefore a final pdf has a smaller file size than the total size of the original images. acrobat compresses tiff uncompressed, lzw, and zip the same amount and produces pdfs of the same file size. because our in-house scanning software does not support tiff g4, we did not include tiff g4 test data here. by comparing similar pages, we concluded that tiff g4 works the same as tiff uncompressed, lzw, and zip. for example, if we scan a text-based page as blackand-white and save it separately in tiff uncompressed, lzw, zip, or g4, then convert each page into a pdf, the final pdf will have the same file size without a noticeable quality difference. tiff jpeg generates the smallest pdf, but it is a lossy format, so it is not recommended. both jpeg and jpeg 2000 have smaller file sizes but generate larger pdfs than those converted from tiff images. recommendations 1. use tiff uncompressed or lzw in 24 bits color for pages with color graphs or for historical documents. 2. use tiff uncompressed or lzw compress an image up to 50 percent. some vendors hesitate to use this format because it was proprietary; however, the patent expired on june 20, 2003. this format has been widely adopted by much software and is safe to use. csul saves all scanned text documents in this format. ■■ tiff zip: this is a lossless compression. like lzw, zip compression is most effective for images that contain large areas of single color. 2 ■■ tiff jpeg: this is a jpeg file stored inside a tiff tag. it is a lossy compression, so csul does not use this file format. other image formats: ■■ jpeg: this format is a lossy compression and can only be used for nonarchival purposes. a jpeg image can be converted to pdf or embedded in a pdf. however, a pdf created from jpeg images has a much larger file size compared to a pdf created from tiff images. ■■ jpeg 2000: this format’s file extension is .jp2. this format offers superior compression performance and other advantages. jpeg 2000 normally is used for archival photographs, not for text-based documents. in short, scanned images should be saved as tiff files, either with compression or without. we recommend saving text-only pages and pages containing text and/or line art as tiff g4 or tiff lzw. we also recommend saving pages with photographs and illustrations as tiff lzw. we also recommend saving pages with photographs and illustrations as tiff uncompressed or tiff lzw. how image format and color mode affect pdf file size color mode and file format are two on-screen viewing and print qualities. in the following sections, we will discuss how to make scanned documents web-friendly. scanning there are three main factors that affect the quality and file size of a digitized document: file format, color mode, and resolution of the source images. these factors should be kept in mind when scanning text documents. file format and compression most digitized documents are scanned and saved as tiff files. however, there are many different formats of tiff. which one is appropriate for your project? ■■ tiff: uncompressed format. this is a standard format for scanned images. however, an uncompressed tiff file has the largest file size and requires more space to store. ■■ tiff g3: tiff with g3 compression is the universal standard for faxs and multipage line-art documents. it is used for blackand-white documents only. ■■ tiff g4: tiff with g4 compression has been approved as a lossless archival file format for bitonal images. tiff images saved in this compression have the smallest file size. it is a standard file format used by many commercial scanning vendors. it should only be used for pages with text or line art. many scanning programs do not provide this file format by default. ■■ tiff huffmann: a method for compressing bi-level data based on the ccitt group 3 1d facsimile compression schema. ■■ tiff lzw: this format uses a lossless compression that does not discard details from images. it may be used for bitonal, grayscale, and color images. it may the next generation library catalog | zhou 153are your digital documents web friendly? | zhou 153 to be scanned at no less than 600 dpi in color. our experiments show that documents scanned at 300 or 400 dpi are sufficient for creating pdfs of good quality. resolutions lower than 300 dpi are not recommended because they can degrade image quality and produce more ocr errors. resolutions higher than 400 dpi also are not recommended because they generate large files with little improved on-screen viewing and print quality. we compared pdf files that were converted from images of resolutions at 300, 400, and 600 dpi. viewed at 100 percent, the difference in image quality both on screen and in print was negligible. if a page has text with very small font, it can be scanned at a higher resolution to improve ocr accuracy and viewing and print quality. table 2 shows that high-resolution images produce large files and require more time to be converted into pdfs. the time required to combine images is not significantly different compared to scanning time and ocr time, so it was omitted. our example is a modern text document with text and a black-and-white chart. most of our digitization projects do not require scanning at 600 dpi; 300 dpi is the minimum requirement. we use 400 dpi for most documents and choose a proper color mode for each page. for example, we scan our theses and dissertations in black-andwhite at 400 dpi for bitonal pages. we scan pages containing photographs or illustrations in 8-bit grayscale or 24-bit color at 400 dpi. other factors that affect pdf file size in addition to the three main factors we have discussed, unnecessary edges, bleed-through of text and graphs, background noise, and blank pages also increase pdf file sizes. figure 1 shows how a clean scan can largely reduce a pdf file size and cover. the updated file has a file size of 42.8 mb. the example can be accessed at http://hdl.handle .net/10217/3667. sometimes we scan a page containing text and photographs or illustrations twice, in color or grayscale and in black-and-white. when we create a pdf, we combine two images of the same page to reproduce the original appearance and to reduce file size. how to optimize pdfs using multiple scans will be discussed in a later section. how image resolution affects pdf file size before we start scanning, we check with our project manager regarding project standards. for some funded projects, documents are required in grayscale 8 bits for pages with black-and-white photographs or grayscale illustrations. 3. use tiff uncompressed, lzw, or g4 in black-and-white for pages containing text or line art. to achieve the best result, each page should be scanned accordingly. for example, we had a document with a color cover, 790 pages containing text and line art, and 7 blank pages. we scanned the original document in color at 300 dpi. the pdf created from these images was 384 mb, so large that it exceeded the maximum file size that our repository software allows for uploading. to optimize the document, we deleted all blank pages, converted the 790 pages with text and line art from color to blackand-white, and retained the color table 1. file format and color mode versus pdf file size file format scan specifications tiff size (kb) pdf size (kb) tiff color 24 bits

technology and libraries | september 2010154 information technology and libraries | september 2010 many pdf files cannot be saved as pdf/a files. if an error occurs when saving a pdf to pdf/a, you may use adobe acrobat preflight (advanced > preflight) to identify problems. see figure 2. errors can be created by nonembedded fonts, embedded images with unsupported file compression, bookmarks, embedded video and audio, etc. by default, the reduce file size procedure in acrobat professional compresses color images using jpeg 2000 compression. after running the reduce file size procedure, a pdf may not be saved as a pdf/a because of a “jpeg 2000 compression used” error. according to the pdf/a competence center, this problem will be eliminated in the second part of the pdf/a standard— pdf/a-2 is planned for 2008/2009. there are many other features in new pdfs; for example, transparency and layers will be allowed in pdf/a2.5 however, at the time this paper was written pdf/a-2 had not been announced.6 portable, which means the file created on one computer can be viewed with an acrobat viewer on other computers, handheld devices, and on other platforms.3 a pdf/a document is basically a traditional pdf document that fulfills precisely defined specifications. the pdf/a standard aims to enable the creation of pdf documents whose visual appearance will remain the same over the course of time. these files should be software-independent and unrestricted by the systems used to create, store, and reproduce them.4 the goal of pdf/a is for long-term archiving. a pdf/a document has the same file extension as a regular pdf file and must be at least compatible with acrobat reader 4. there are many ways to create a pdf/a document. you can convert existing images and pdf files to pdf/a files, export a document to pdf/a format, scan to pdf/a, to name a few. there are many software programs you can use to create pdf/a, such as adobe acrobat professional 8 and later versions, compart ag, pdflib, and pdf tools ag. simultaneously improve its viewing and print quality. recommendations 1. unnecessary edges: crop out. 2. bleed-through text or graphs: place a piece of white or black card stock on the back of a page. if a page is single sided, use white card stock. if a page is double sided, use black card stock and increase contrast ratio when scanning. often color or grayscale images have bleedthrough problems. scanning a page containing text or line art as black-and-white will eliminate bleed-through text and graphs. 3. background noise: scanning a page containing text or line art as black-and-white can eliminate background noise. many aged documents have yellowed papers. if we scan them as color or grayscale, the result will be images with yellow or gray background, which may increase pdf file sizes greatly. we also recommend increasing the contrast for better ocr results when scanning documents with background colors. 4. blank pages: do not include if they are not required. blank pages scanned in grayscale or color can quickly increase file size. pdf and longterm archiving pdf/a pdf vs. pdf/a pdf, short for portable document format, was developed by adobe as a unique format to be viewed through adobe acrobat viewers. as the name implies, it is table 2. color mode and image resolution vs. pdf file size color mode resolution (dpi)

is the only option used by csul. 2. searchable image: ensures that text is searchable and selectable. this option keeps the original image, de-skews it as needed, and places an invisible text layer over it. the selection for downsample images in this same dialog box determines whether the image is downsampled and to what extent.9 the downsampling combines several pixels in an image to make a single larger pixel; thus some information is deleted from the image. however, downsampling does not affect the quality of text or line art. when a proper setting is used, the size of a pdf can be significantly reduced with little or no loss of detail and precision. 3. clearscan: synthesizes a new type 3 font that closely approximates the original, and preserves the page background using a low-resolution copy.10 the final pdf is the same as a born-digital pdf. because acrobat cannot guarantee the accuracy of manipulate the pdf document for accessibility. once ocr is properly applied to the scanned files, however, the image becomes searchable text with selectable graphics, and one may apply other accessibility features to the document.7 acrobat professional provides three ocr options: 1. searchable image (exact): ensures that text is searchable and selectfull-text searchable pdfs and troubleshooting ocr errors a pdf created from a scanned piece of paper is inherently inaccessible because the content of the document is an image, not searchable text. assistive technology cannot read or extract the words, users cannot select or edit the text, and one cannot figure 1.

technology and libraries | september 2010156 information technology and libraries | september 2010 but at least users can read all text, while the black-and-white scan contains unreadable words. troubleshoot ocr error 3: cannot ocr image based text the search of a digitized pdf is actually performed on its invisible text layer. the automated ocr process inevitably produces some incorrectly recognized words. for example, acrobat cannot recognize the colorado state university logo correctly (see figure 6). unfortunately, acrobat does not provide a function to edit a pdf file’s invisible text layer. to manually edit or add ocr’d text, adobe acrobat capture 3.0 (see figure 7) must be purchased. however, our tests show that capture 3.0 has many drawbacks. this software is complicated and produces it’s own errors. sometimes it consolidates words; other times it breaks them up. in addition, it is time-consuming to add or modify invisible text layers using acrobat capture 3.0. at csul, we manually add searchable text for title and abstract pages only if they cannot be ocr’d by acrobat correctly. the example in troubleshoot ocr error 2: could not perform recognition (ocr) sometimes acrobat generates an “outside of the allowed specifications” error when processing ocr. this error is normally caused by color images scanned at 600 dpi or more. in the example in figure 4, the page only contains text but was scanned in color at 600 dpi. when we scanned this page as blackand-white at 400 dpi, we did not encounter this problem. we could also use a lower-resolution color scan to avoid this error. our experiments also show that images scanned in black-and-white work best for the ocr process. in this article we mainly discuss running the ocr process on modern textual documents. black-and-white scans do not work well for historical textual documents or aged newspapers. these documents may have faded text and background noise. when they are scanned as blackand-white, broken letters may occur, and some text might become unreadable. for this reason they should be scanned in color or grayscale. in figure 5, images scanned in color might not produce accurate ocr results, ocred text at 100 percent, this option is not acceptable for us. for a tutorial on to how to make a full-text searchable pdf, please see appendix a. troubleshoot ocr error 1: acrobat crashes occasionally acrobat crashes during the ocr process. the error message does not indicate what causes the crash and where the problem occurs. fortunately, the page number of the error can be found on the top shortcuts menu. in figure 3, we can see the error occurs on page 7. we discovered that errors are often caused by figures or diagrams. for a problem like this, the solution is to skip the error-causing page when running the ocr process. our initial research was performed on acrobat 8 professional. our recent study shows that this problem has been significantly improved in acrobat 9 professional. figure 3. adobe acrobat 8 professional crash window figure 4. “could not perform recognition (ocr)” error figure 5. an aged newspaper scanned in color and black-and-white aged

the undesirable marks and background contribute to its large file size and create ink waste when printed. method 2: running acrobat’s built-in optimization processes acrobat provides three built-in processes to reduce file size. by default, acrobat use jpeg compression for color and grayscale images and ccitt group 4 compression for bitonal images. optimize scanned pdf open a scanned pdf and select documents > optimize scanned pdf. a number of settings, such as image quality and background removal, can be specified in the optimize scanned pdf dialog box. our experiments show this process can noticably degrade images and sometimes even increase file size. therefore we do not use this option. reduce file size open a scanned pdf and select documents > reduce file size. the reduce file size command resamples and recompresses images, removes embedded base-14 fonts, and subset-embeds fonts that were left embedded. it also compresses document structure and cleans up elements such as invalid bookmarks. if the file size is already as small as possible, this command has no effect.11 after process, some files cannot be saved as pdf/a, as we discussed in a previous section. we also noticed that different versions of acrobat can create files of different file sizes even if the same settings were used. pdf optimizer open a scanned pdf and select advanced > pdf optimizer. many settings can be specified in the pdf optimizer dialog box. for example, we can downsample images from sections, we can greatly reduce a pdf’s size by using an appropriate color mode and resolution. figure 9 shows two different versions of a digitized document. the source document has a color cover and 111 bitonal pages. the original pdf, shown in figure 9 on the left, was created by another university department. it was not scanned according to standards and procedures adopted by csul. it was scanned in color at 300 dpi and has a file size of 66,265 kb. we exported the original pdf as tiff images, batch-converted color tiff images to black-and-white tiff images, and then created a new pdf using blackand-white tiff images. the updated pdf has a file size of 8,842 kb. the image on the right is much cleaner and has better print quality. the file on the left has unwanted marks and figure 8 is a book title page for which we used acrobat capture 3.0 to manually add searchable text. the entire book may be accessed at http://hdl .handle.net/10217/1553. optimizing pdfs for web delivery a digitized pdf file with 400 color pages may be as large as 200 to 400 mb. most of the time, optimizing processes may reduce files this large without a noticeable difference in quality. in some cases, quality may be improved. we will discuss three optimization methods we use. method 1: using an appropriate color mode and resolution as we have discussed in previous ~do university original logo text ocred by acrobat figure 6. incorrectly recognized text sample figure 7. adobe acrobat

pages that were scanned with different color modes and resolutions. a pdf may also have pages of mixed resolutions. one page may contain both bitonal images and color or grayscale images, but they must be of the same resolution. the following strategies were adopted by csul: 1. combine bitmap, grayscale, and color images. we use grayscale images for pages that contain grayscale graphs, such as black-and-white photos, color images for pages that contain color images, and bitmap images for text-only or text and line art pages. 2. if a page contains high-definition color or grayscale images, scan that page in a higher resolution and scan other pages at 400 dpi. 3. if a page contains a very small font and the ocr process does not work well, scan it at a higher resolution and the rest of document at 400 dpi. 4. if a page has both text, color, or grayscale graphs, we scan it twice. then we modify images using adobe photoshop and combine two images in acrobat. in figure 10, the grayscale image has a gray background and a true reproduction of the original photograph. the black-and-white scan has a white background and clean text, but details of the photograph are lost. the pdf converted from the grayscale image is 491 kb and has nine ocr errors. the pdf converted from the black-and-white image is 61kb and has no ocr errors. the pdf converted from a combination of the grayscale and black-and-white images is 283 kb and has no ocr errors. the following are the steps used to create a pdf in figure 10 using acrobat: 1. scan a page twice—grayscale optimizer can be found

of pages are textonly. it is not necessary to scan all pages of such documents in color or a higher resolution to a lower resolution and choose a different file compression. different collections have different original sources, therefore different settings should be applied. we normally do several tests for each collection and choose the one that works best for it. we also make our pdfs compatible

scanner. acrobat 9 provides five options: black and white document, grayscale document, color document, color image, and custom scan. the custom scan option allows you to scan, run the ocr procedure, add metadata, combine multiple pages into one pdf, and also make it pdf/a compliant. to create a pdf from a scanner, go to file > create pdf > from scanner > custom scan. see figure 1. at csul, we do not directly create pdfs from scanners because our tests show that it can produce fuzzy text and it is not time efficient. both scanning and running the ocr process can be very time consuming. if an error occurs during these processes, we would have to start over again. we normally scan images on scanning stations by student employees 160 information technology and libraries | september 2010160

assistive technology cannot read or extract the words, users cannot select or edit the text, and one cannot manipulate the pdf document for accessibility. once optical character recognition (ocr) is properly applied to the scanned files, however, the image becomes searchable text with selectable graphics, and one may apply other accessibility features to the document. adobe acrobat professional provides three ocr options, searchable image (exact), searchable image, and clean scan. because searchable image (exact) is the only option that keeps the original look, we only use this option. to run an ocr procedure using acrobat 9 professional: 1. open a digitized pdf. 2. select document > ocr text recognition > recognize text using ocr. 3. in the recognize text dialog, specify pages to be

(edavispatsfan@gmail.com) is library specialist, hoover public library. abstract smart voice assistants have expanded from personal use in the home to applications in public services and educational spaces. the library and information science (lis) trade literature suggests that libraries are part of this trend, however there are few empirical studies that explore how libraries are implementing smart voice assistants in their services, and how these libraries are mitigating the potential patron data privacy issues posed by these technologies. this study fills this gap by reporting on the results of a national survey that documents how libraries are integrating voice assistant technologies (e.g., amazon echo, google home) into their services, programming, and checkout programs. the survey also surfaces some of the key privacy concerns of library workers in regard to implementing voice assistants in library services. we find that although voice assistant use might not be mainstreamed in library services in high numbers (yet), libraries are clearly experimenting with (and having internal conversations with their staff about) using these technologies. the responses to our survey indicate that library workers have many savvy privacy concerns about the use of voice assistants in library services that are critical to address in advance of library institutions riding the wave of emerging technology adoption. this research has important implications for developing library practices, policies, and education opportunities that place patron privacy as a central part of digital literacy in an information landscape characterized by ubiquitous smart surveillant technologies. introduction smart voice assistant use has expanded from personal uses in the home to new applications in customer services, healthcare, e-government, and educational spaces, raising questions from groups like the american civil liberties union (aclu), among others, about the data privacy implications of these technologies in public and shared spaces.1 libraries are part of the voice assistant adoption trend, as documented in the american libraries magazine article “your library needs to speak to you” by carrie smith.2 smith gives examples of school, public, and academic libraries adopting smart voice assistants like amazon’s alexa and echo devices for a range of services and programming including “event calendars, catalog searches, holds, and advocacy.” nicole hennig points out that there are tremendous opportunities for voice assistants to assist “people with disabilities, the elderly, and people who can’t easily type.”3 in these ways, voice assistants are often presented in the trade literature as part of an exciting new wave of emerging smart technology services that libraries can “get ahead of” and potentially harness for public service and community engagement. at the same time, the key privacy issues inherent in voice assistants are often downplayed as secondary concerns while librarians are encouraged to press forward and experiment with smart technology adoption. we argue that the privacy concerns surrounding voice assistant use in libraries should be treated as fundamental questions for library mailto:mesweeney1@ua.edu mailto:edavispatsfan@gmail.com information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 2 workers to consider as a part of upholding the core values of patron privacy and confidentiality in library services. voice assistant use in libraries is still nascent, reflecting the emerging nature of these technologies. given this, it is not surprising that very few empirical studies have explored voice assistant use and potential data privacy implications for libraries. our research is intended as an exploratory study that contributes to advancing knowledge in this area. the goals of this study are to begin mapping smart voice assistant use in libraries, to assess how aware library workers are of privacy concerns involving these technologies, and document how library workers are educating patrons about privacy and voice assistant use. these are necessary first steps for developing library practices, policies, and education opportunities for voice assistant use that prioritize privacy as a central part of digital literacy in an information landscape characterized by ubiquitous smart surveillant technologies and diminishing data privacy protections. review of literature what is a voice assistant? voice assistants are a type of digital assistant technology, also known as virtual assistants, and can be broadly defined as computer programs designed with human characteristics that act on behalf of users in digital environments using voice interfaces.4 apple’s siri, microsoft’s cortana, and amazon’s alexa are prevalent examples of smart digital assistants that use voice recognition and natural language user interfacing to help learn users’ preferences, answer questions, and manage a variety of applications and personal information. voice assistants can run on multiple devices and be seamlessly integrated across platforms including networked internet of things (iot) gadgets like smart speakers (e.g., amazon echo and google home) and other smart-home technologies (e.g., nest or ring), along with mobile devices, smart watches, personal computers, and numerous third-party applications. ubiquitous “always on” features are offered as a convenience to users who can use “wake words” (e.g., “hey, siri”; “alexa”; “ok google”) to initiate queries and commands. amazon’s smart speakers and intelligent digital assistants are rapidly becoming pervasive home and personal technologies, with the amazon echo leading the market in 2019 with 61 percent market share, followed distantly by the google home device with 24 percent market share.5 a recent united states survey by clutch reported that nearly half of people surveyed owned a voice assistant, with one-third planning to purchase one in the next three years.6 additionally, the clutch survey found that 69 percent of voice assistant owners used their devices every day.7 the popularity of voice assistants for personal use has driven the expansion of these technologies for customer service applications outside of the home in shared and public spaces, including in educational settings and health care. in this landscape it is perhaps not surprising that librarians are following suit and exploring the service potentials of voice assistants for libraries. libraries and voice assistant use the american library association’s (ala) center for the future of libraries initiative identified “voice control” as a trend in their 2017 report, anticipating the relevance of voice assistant technologies for libraries.8 the capability of voice assistants to integrate across platforms through customized applications—which amazon calls “skills” and google refers to as “actions”—allows libraries to create specialized uses for these technologies as a part of their regular information services. additionally, existing third-party vendors like overdrive (for e-book lending) and hoopla (multimedia lending) that most public libraries use are preconfigured to connect to voice information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 3 assistants like amazon’s alexa. there are many creative and potentially helpful ways that voice assistants could be integrated into the library setting, including enhancing read-along with music and effects, providing accessible services for elderly patrons or individuals with disabilities, and providing an alternative access point for common library queries and institutional information (e.g., searching titles, placing holds, requesting library event information).9 some libraries have started experimenting with voice assistant services in the library. for example, iowa state university staff developed alexa skills for their library so that users could find out information about library history and library collections.10 other libraries are using voice assistants to strategically engage their communities, as when the spokane public library placed amazon echo dots in the library so patrons could ask questions about upcoming bond elections, an issue that directly impacts library funding.11 the worthington (oh) libraries are integrating voice assistant technologies into technology training and “petting zoo kits” which allow their patrons to try out emerging technologies.12 the king county (wa) library system is taking a novel approach and experimenting with developing their own voice assistant, libro.13 these examples point to the many applications and creative approaches libraries are experimenting with to bring voice assistant technology to their services. data privacy issues as convenient as voice assistants may be for library services, the underlying data infrastructures of these technologies are tightly controlled by the technology companies that design and sell them. the lack of library control (and transparency) over these infrastructures raises questions about how the core values of privacy and confidentiality can be guaranteed in the library setting. 14 voice assistant technologies capture a wide range of intimate user information in the form of biometric data (e.g., voice recognition), consumer habits, internet-based transactions, personally identifiable information (pii), and geographical information.15 the ubiquitous “always on” feature that makes these technologies so convenient also flags important privacy questions about the extent of user interactions that are recorded; how these files are processed, transcribed, and stored; and how local, state or other law enforcement agencies might compel or otherwise use these records.16 recently amazon has confirmed that they have employees dedicated to listening to recordings from echo devices in order to help “eliminate the gaps in alexa’s understanding of human speech and help it better respond to commands,” which is concerning for patron privacy in the library context.17 researchers at northeastern university and imperial college london recently did a study about how often smart speakers record “accidentally” and whether or not they are constantly recording. the study found no evidence to support the theory that these devices are constantly recording, however the researchers did report that smart speakers are accidentally activated around 19 times a day, on average. 18 these reports aside, there is still much unknown about what these companies, and the companies they contract out work to, do with the personal data collected from voice assistants. lastly, amazon is a known collaborator with us government agencies like homeland security and immigration and customs enforcement (ice), hosting their biometric data on amazon web services (aws).19 amazon has a reputation for being one of the least transparent technology companies in terms of data sharing practices, and has routinely evaded questions about if/how much of customers’ echo data has been turned over to federal authorities.20 given this data environment, the fact that libraries are beginning to experiment with voice assistant integration in their services poses important questions for patron data privacy and confidentiality. ala provides library privacy guidelines for third-party vendors that clearly detail information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 4 expectations for use, aggregation, retention, and disclosure of user data. 21 while this document has been helpful for guiding license agreements with digital content providers, program facilitators, and other libraries, it does not quite capture the range of complexities that emerging smart technologies pose in the app-driven iot landscape. this area is ripe for study and having more information about how libraries of different types are approaching using voice assistants is necessary for developing responsive professional practices that center issues of privacy and critical digital literacy. our survey explores some of these issues with the purpose of beginning to document voice assistant use, and associated privacy concerns, in library services. research methods four main research questions guide this study: (1) how are libraries using smart voice assistant technologies as a part of their library services? (2) how aware are library workers of how voice assistants integrate with third-party digital content platforms? (3) are libraries educating library patrons about the privacy implications of smart voice assistant technologies? and (4) what kinds of privacy concerns do library workers have about the use of smart voice assistant technologies in their library services and programming? to address these questions, we developed an online survey using qualtrics web software, and distributed it in fall 2019 to 1,929 public and academic libraries across the us via email solicitation.22 the survey consisted of a mix of 31 multiple choice and open-ended questions designed to address different aspects of the stated research questions (see appendix a). since most of the examples of library voice assistant use detailed in the lis trade literature came from public and academic libraries, these were the library types we identified as most likely to already be experimenting with voice assistants in services and programming. using purposive sampling techniques, we selected 30 public libraries for each state that represented a range of rural and metropolitan service areas. we selected approximately 10-20 academic libraries per state, the actual numbers ranging based on the total number of universities and colleges in a given state. we identified a cross-section of large state schools, private colleges, and community colleges in each state to account for the variety of higher education institutional settings for academic libraries. we sent email solicitations to each public library, targeting email addresses for library directors where possible. for libraries that had centralized email services, we solicited participation using the contact forms available on the libraries’ websites. email solicitations to the academic libraries targeted library employees with job titles that included: emerging technology, user services, user experiences, head of public services, and head of technology. our survey analysis documents the numbers of reported uses, and kinds of integration, of voice assistant technologies across library applications and services. we conducted a qualitative content analysis of the short answer responses, with both researchers independently coding participant comments for emergent themes and categories. as a part of this process both researchers compared and negotiated categories in two iterations of coding to arrive at a common codebook which was then applied in the final pass of the responses. these categories have some distinct features, but also have many overlapping components. comments that embodied multiple themes were included in all categories that were relevant for describing them, meaning a particular comment might be included in multiple categories. the following sections report on the key findings of this study, organizing the discussion around our original research questions. information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 5 findings participant demographics we received 86 total responses for the survey, with the majority of respondents (61 percent) reporting affiliation with public libraries, followed by respondents from academic libraries (38 percent), with one respondent from a school library (1 percent).23 the participants represented libraries from 42 states across the us.24 the vast majority of public library respondents (65 percent) reported serving populations of 25,000 or more, though there was also a large reporting from libraries serving smaller populations of 2,500-9,999. the majority of academic library respondents work for small and medium sized institutions serving populations between 2,5009,999 (table 1), with nearly a third of respondents representing medium to large institutions. admittedly, these are rough demographic sketches to help quickly identify which types of libraries might be using voice assistants. more granular demographic detail would be useful in future studies to further understand how factors like institution type, geographical region, access to resources, and service community demographics shape decisions about emerging technology adoption in libraries. table 1. size of service population by library type total public academic school total count 84 51 32 1 2,5000 or less 11.9% 2.0% 28.1% 0.0% 2,500-9,999 25.0% 19.6% 34.4% 0.0% 10,000-25,000 16.7% 11.8% 25.0% 0.0% 25,000+ 44.0% 64.7% 12.5% 0.0% i’m not sure. 2.4% 2.0% 0.0% 100.0% how are libraries using smart voice assistant technologies as a part of their library services? only five respondents (6 percent) in our study reported that their library is currently using amazon echo, google home, or apple siri devices for patron services and programming. of the voice assistant adopters, three were public libraries using amazon echo and google home devices, and two were academic libraries using amazon echo and apple siri (table 2). table 2. voice assistant device by library type total public academic school amazon echo 3 1 2 0 google home 2 2 0 0 apple siri 1 0 1 0 librarians described using voice assistants to “provide basic info about the library and resources,” and on an “ad hoc basis” to promote the library-specific alexa skills and google home actions. other reported uses included “translation services” and as a part of “technology petting zoos.”25 we asked librarians to describe where voice assistants were located in the library to get a better idea of the spatial arrangements of these technologies, which could be important for considering potential surveillant concerns. several libraries reported that they had voice assistants sitting at front service desks or reference desks for patrons to use in both adult and children’s service areas, information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 6 as well as at circulation desks. as one librarian described, “we are mounting it [the voice assistant] so students/users can ask questions when necessary.” when it comes to using these devices in library programming, the most common response was for use in technology petting zoos and in technology classes where patrons can see technology demonstrations and ask library staff questions, or get on-on-one tutoring sessions: “our technology department holds regular ‘tech drop-in's’ and carries out one on one assistance by appointment. in the context of these patrons will sometimes bring in their own devices or ask questions about the use of digital assistants.” other programming applications that librarians mentioned for voice assistants included trivia, 3 -d printing, and makerspaces. two libraries (one public and one academic) reported that they were circulating apple siri devices (e.g., ipads) and amazon alexa products (e.g., echo) for checkout. how aware are library workers of how voice assistants integrate with third-party digital content platforms? the majority of library workers surveyed (70 percent) reported that their libraries use third-party digital media platforms like overdrive and hoopla to provide multimedia content like e-books and streaming video to patrons. both of these platforms support integration with voice assistants like amazon alexa through “skills” (the alexa equivalent of an application). patrons are able to download a skill for their alexa-enabled device to access digital content through these platforms, which are often linked to their library accounts (e.g., “alexa, ask hoopla how many borrows i have remaining.”).26 around 14 percent of the respondents reported that they were aware that overdrive and hoopla integrated with voice assistants, and 3 percent of all respondents reported that their libraries actively inform patrons about amazon alexa skills for these services. when patrons begin connecting their personal voice assistant devices with third -party digital content providers that are also linked to their library accounts, different terms of service agreements and privacy policies overlap creating a complex data rights landscape. almost a third of our respondents (29 percent) replied that they were aware that amazon has different privacy policies from overdrive and hoopla, with 22 percent responding that they were unaware of these differences (the rest were unsure or did not respond). only 15 percent of respondents reported that their libraries provided patrons with information about overdrive and hoopla’s privacy policies. one library worker offered that, “when helping a patron or informing them that we use overdrive they are encouraged to read all the privacy info.” however, no libraries in this study reported sharing information about amazon’s privacy policies with patrons, which might also apply to linked accounts. lastly, 34 percent of the library workers indicated that they were familiar with the ala guidelines on privacy that pertain to third-party vendors, and 16 percent reported that their library actively refers to these guidelines in information materials for patrons. for instance, “we have a privacy policy on our website, which was based on the ala library privacy checklists. it states that our vendors have different privacy policies than we do.” these responses indicate that while some library workers are aware of the privacy implications of the integration of voice assistants into third-party digital content platforms, there are opportunities to increase staff and patron awareness about the intersecting privacy policies and terms of service in this landscape. information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 7 are libraries educating library patrons about voice assistant technologies as a part of services and programming? we were curious if the libraries who used voice assistants in their services were taking any particular measures to inform patrons about the privacy implications of these technologies, or offering any other kinds of specific privacy “best practices” guides for use (e.g., how to erase your data records, adjust settings, etc.). the two libraries who reported circulating voice assistants indicated that they did not include any privacy information with voice assistant devices at checkout. similarly, we asked library workers about the kinds of technology classes or programming that their libraries were offering, since these might be sites where there is potential to educate or provide information about privacy issues raised by smart technologies like voice assistants. we found that 49 (56 percent) of the libraries represented in the survey (37 public, 12 academic) offer technology courses for the public. of these, 39 libraries (24 public, 15 academic) responded “yes” to our question asking if aspects of “data privacy or data literacy” are included as part of these classes or other related programming.27 only 3 libraries (2 public, 1 academic) were able to report that their library offers data literacy education that specifically addresses voice assistant technologies. library workers provided many examples of the kinds of data literacy information that their libraries typically provided in technology classes and programming. twelve respondents said that their libraries offered some sort of broad data literacy class and several cited classes specifically targeted at personal data practices and security. topics taught in these classes included: understanding your personal risk profile; password managers and security; how to understand and protect your digital footprint; and sessions on facebook and google where staff “walk users through how to find their information and make decisions about it.” several respondents identified information literacy topics in conjunction with data literacy, noting that their library teaches classes about identifying “fake news,” phishing scams, and evaluating the authority of websites and website content. none of the responses specifically named issues around privacy or data capture by voice assistants or other smart technologies as topics covered in library technology classes. several library workers noted that technology classes were offered at their libraries through one-on-one sessions, geared to individually address what patrons had questions about. based on these responses it is unclear how in-depth, or if at all, these one-on-one sessions might go into informing patrons about privacy best practices and risks when using smart technologies like voice assistants. what kinds of privacy concerns do library workers have about the use of smart voice assistant technologies in their library services and programming? just over half of the library workers surveyed (52 percent) answered “yes” to the question: “do you have any privacy concerns about the use of amazon echo, google home, or apple siri devices in the library?” of the other responses, 16 percent reported “no” concerns and 15 percent answered “i’m not sure.” those who answered yes were asked to further describe their privacy concerns, resulting in robust descriptions that demonstrated a savvy understanding of the voice assistant data landscape. we characterized library workers’ concerns about voice assistants in the library by five major categories: data access and use; surveillance and “always on” features; procedure and operations; legal issues; and professional responsibility. data access and use by far the most prevalent privacy concerns focused on questions about who has access to data collected by smart voice assistants and how this data might be used (or misused) by different information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 8 parties. library workers were the most concerned about the reach of access that the three major voice assistant parent companies (amazon, google, apple) have to patron data, closely accompanied by concerns with the selling of this data to third-party vendors: “there are known risks in the logging practices of the assistant vendor (amazon, google, apple). there are potentially greater, and unknown, risks of privacy and data security problems with third-party integrators that libraries are working with to create the alexa skills, google home actions, etc.” “these devices are tied to user accounts for vendors that sell goods and services. there are opportunities to make purchases that we do not want to present to our patrons.” “as currently constituted, most of these devices' privacy policies require owners to allow voice recordings to be sent to cloud services for transcription and, in some instances, for storage and for re-listening by staff or 3rd-party contractors.” another library worker added that they were concerned about the willingness of these parent companies to “share personal, private data with law enforcement agencies.” this observation underscores what is potentially at stake in terms of patron vulnerability in this data environment. several concerns focused on patrons “unwittingly leaving their sensitive information on devices that we might use.” “being that anything we use in the library, or check out to our patrons is shared, i have privacy concerns for what data and recordings will be collected by the services while they are either in use in the library or while they are in the patron’s possession.” while some of these concerns were tied back to how parent companies might use this data, others were equally wary of the potentials for “storing information that can be accessed between patron uses” or by library staff: “as with computers in the info commons, i would be concerned whether user information is scrubbed after each user. or would one user's information persist and become available to a subsequent user.” “i would not want to be able to identify the patron who used the device. in this case, we cannot. we circulate ipads as assistive devices. as soon as the item is returned, the checkout record is purged.” lastly, library workers expressed cybersecurity concerns about voice assistants, wondering about how voice assistants might be hacked or otherwise manipulated by malicious actors: “the library is public space, these devices are not known for being secure. a device would have to be registered to some university account, but would be prone to algorithmic manipulation from public voice inputs if that makes sense?” “just the idea that they (everything!) is [sic] hackable, and hostage-able, and so on, creeps me out personally, but also in terms of privacy and confidentiality of users of that technology.” information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 9 “alexa and google home can be hacked to phish passwords and other sensitive information.” taken together, these concerns gesture to the opacity of the data environment in terms of who might have access to data (companies, law enforcement, patrons, library staff, hackers) and how this data might be used (advertising and marketing, exposure of personal patron information, state surveillance, and exploitation). surveillance and “always on” features the second major area of concern that library workers expressed was about the surveillance potentials of voice assistants via their passive listening features. in order for voice assistants to respond to their various wake words, they need to be “always on” and listening. while there is a difference between always listening and always recording (which recent studies suggest is no t happening), library workers remained wary about devices “constantly monitoring staff or patrons.”28 these concerns have some obvious overlap to the data access and use theme, but differ in that they are specifically concerned with the act of surveilling—monitoring—patron activities, use patterns, and personal information. three respondents in this category couched their data privacy concerns in terms of ability to exert some control over their data (e.g., deleting data), or the ability to grant permission/consent to be recorded: “these devices are intended for use in the home. they offer some protections for users with management access. for example, the google assistant allows review and deletion of recording history. for users without such access there are no such protections.” “...they [voice assistants] are intended to for use inside a single household, learning the voices, habits and preferences of those household members. i feel that this kind of personal information should be the individual's choice to make and not the library's [sic].” “my concern is that my personal data is being collected without my permission. the same concern applies to patrons of the library. having them present and turned on captures people's conversations and they may not be aware that is happening.” as these comments suggest, passive listening in public spaces opens up the potential for surveilling patrons and library staff who are not intending to interact with the devices, or who have no knowledge that the device is present. in other words, while some patrons might opt to use a voice assistant to ask a question or look a book up in a library catalog, patrons (and library staff) who are merely talking in the vicinity of these devices may still be listened to and recorded by these devices without their knowledge or consent. this group of privacy concerns conveys a lack of transparency around data collection and surveillance in voice assistants, pointing to larger power differentials between parent companies and users in terms of control over data collection and management. procedure and operations library workers discussed the operational challenges that voice assistants present to staff in terms of establishing routine procedures that ensure patron privacy and confidentiality in between patron use: information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 10 “how do we make sure no residual information remains in the device before someone else uses it or that if used during a program 'private' information isn't being broadcast to other devices in the area?” another library worker alluded to some of the operational considerations that already accompany library use and lending of personal computing devices, “clearing data, purchasing, maintaining, we already have ipads and other devices and their management with our staff has been a challenge.” this comment points to the extra staff labor that underpins technology services, which is often not considered as a part of infrastructure for offering these services. similarly, there is a sense from these comments that establishing procedures to maintain privacy and confidentiality are critical for voice assistants. failure to erase or secure patron data could lead to inadvertently exposing sensitive or personally identifiable information (pii). “patron's [sic] may inadvertently be saving their information or staff may forget to delete information causing the previous patrons sensitive information to remain for the next patron to discover.” while google home and amazon alexa devices do provide the ability for individual recordings to be deleted by the account holder, in the case of shared library use of voice assistants, it would likely be incumbent on a library staff member to access and delete recordings. this raises ethical, legal, and operational questions for library staff required to manage any patron data collected by voice assistants. in any case, procedural concerns are a reminder that library staff have an active role to take in ensuring patron privacy. legal issues library workers in this study identified three legal issues posed by voice assistants in the library. the first legal issue raised was the potential for violation of the family educational rights and privacy act (ferpa)—the federal law that protects the privacy of student education records—due to the collection of pii by voice assistants. library workers in many academic settings are required to maintain compliance with ferpa. one of the respondents was concerned that by using voice assistants in their services, libraries would be putting themselves in a position to potentially violate this law. a second set of concerns focused on questions about the liability of the library (or individual library workers) if a patron’s pii is misused by technology companies or the third-party vendors who have access to user data: “i have great concerns regarding the use of this technology in a library setting since it might expose the library to potential liability if, more likely when patron data is misused by the technology providers.” related to this concern, another library worker asked, “who owns the info?” questions about rights and ownership of personal data by technology companies, itself a fraught and opaque legal area, require more ethical and legal probing as libraries become intermediaries to patron use of voice assistants. lastly, one library worker cited concerns about librarians’ ability to uphold first amendment rights with voice assistants. information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 11 “we take our mandated role to uphold first amendment rights and patron privacy very seriously. there are too many issues with the way these for-profit companies collect, store and potentially use information. we see no benefits of service gained that offset these concerns. we are also concerned about the way owners of these products use their wealth to leverage political influence.” this comment identifies privacy as a necessary condition for facilitating free speech, contrasting this with a sketch of the political and economic motives underlying voice assistant development. the concerns raised by these library workers point to the complexity of managing patron data in the context of a variety of existing legal frameworks. professional responsibility three respondents explicitly placed privacy concerns in the context of their professional responsibility as library workers to “protect” patrons and patron privacy. a fourth respondent voiced a twin concern about “the library's inability to protect privacy and patron information” (emphasis added). beyond descriptions of protecting patrons, these library workers framed privacy as a professional value. comments such as, “we take our mandated role to uphold first amendment rights and patron privacy very seriously,” emphasize privacy as a professional charge. these kinds of comments tacitly draw on lis professional core values and ethics statements to position responsible professional practice as the action of upholding privacy. as a result, professional identity is discursively constructed by these library workers as a function of valuing privacy. the following comment, particularly, draws an identity-based line between “us” (library professionals) and “them” (technology companies) that is based on divergent values surrounding privacy: “since one of the main concerns we (should) have as library professionals is patron privacy; ‘teaming up’ with technology providers who do not have that level of concern is problematic at best.” the assertion that library core values may be in conflict with the technology providers that are designing voice assistants is very astute, and important for libraries to consider when weighing the decision to experiment with these (and other) emerging smart technologies. discussion: key considerations for library professionals our research suggests that library use of voice assistants poses many as-of-yet unresolved privacy issues for library staff and patrons alike. though voice assistant use is still fairly nascent across public and academic libraries, our study confirms that these tools are already being adopted by some libraries. the adoption of these, and other, smart technologies, is likely to keep trending in library services across institution types, paralleling market trends for personal adoption of voice assistants. many library workers in our study expressed astute concerns about voice assistants, raising important questions about how patron data was collected, managed, and used across the data lifecycle of these technologies. this is a critical moment, then, for the library profession to take stock of questions of privacy surrounding voice assistants, and an opportunity to set a broader professional agenda for data-privacy that encompasses the complexities of smart technology use in library services. in this spirit, we have identified several main areas of concern that emerged from our study, posited as key considerations about voice assistants for library professionals to grapple with. information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 12 circulation procedures for libraries who are, or are considering, lending voice assistant-enabled technologies, clear lending rules are needed for patrons that set guidelines for disconnecting their personal amazon, apple, or google accounts before returning the device. likewise, it is important to develop procedures for library staff to anticipate instances when patrons forget to disconnect their personal accounts. library workers cannot, and should not, be responsible for disconnecting personal accounts as a protective measure for both staff and patrons, since doing so asks library workers to access and take responsibility for personal patron data, including pii. one suggestion might be to require devices to be restored to factory settings, which could be verified by a library staff member at time of device return. libraries might also consider including privacy best practices with these devices that outline known privacy risks and provide information about how to adjust settings to limit data sharing or delete records in personal accounts where applicable (e.g., amazon). third-party digital content platforms the integration of voice assistants in third-party digital content platforms licensed by libraries is becoming more common, pointing to the complexity of upholding patron data privacy throughout these layered and linked services. this issue speaks to the difficulties navigating overlapping privacy statements and terms of service agreements, which is not unique to voice assistants but does indicate the need for more data protections and consumer-oriented information policies. ala already does advocacy work on these issues and provides many helpful guidelines , such as the library privacy guidelines for vendors (http://www.ala.org/advocacy/privacy/guidelines/vendors). still, the data environment is very much characterized by the unequal power differential between technology companies and users. we are in dire need of more robust information policy frameworks that are predicated on transparency, strict parameters for data collection and use, corporate accountability, and user control and agency. a promising example of this is the general data protection regulation (gdpr) implemented in the european union in 2018. something similar is needed in the us to regulate corporate data-sharing practices and give users more control over their data. this would be beneficial across the board for the public, as well as to library patrons using their personal voice assistant devices to access library resources. education opportunities for expanding digital literacy library workers in our study reported a range of technology education and digital literacy programming initiatives in their libraries, though none that specifically addressed voice assistants. this suggests that library technology programming might not be targeting the kinds of specific privacy concerns posed by smart technologies like voice assistants. as smart technologies like voice assistants become more common for household/personal use, it would make sense to expand library programming initiatives to include informational sessions that incorporate data privacy considerations for smart technologies in addition to skills-driven sessions. additionally, some survey responses indicated that library workers may have some knowledge gaps or a lack of concern about voice assistant use. this might point to a need for expanded education, training, and professional development around data privacy issues and emerging technologies for library workers. there has already been a large push in the field to expand digital literacy, defined by ala as “the ability to use information and communication technologies to find, evaluate, create, and communicate information, requiring both cognitive and technical skills.”29 however, this definition of digital literacy falls short of considering the role of assessing data collection, storage, and use as a core part of digital knowledge. expanding digital literacy training, for both staff and http://www.ala.org/advocacy/privacy/guidelines/vendors information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 13 patrons, to include awareness of the data ecosystems and privacy concerns that undergird smart technologies is a must for responsive library services. surveilling patrons and staff voice assistants placed in public service areas, in the library stacks, and in public gathering areas within the library raise the ethical issue of recording patrons (and staff) who either do not wish to be recorded, or do not even know they may be recorded. in the case of library staff, this poses a labor issue where staff may be asked to work in areas where devices may be listening to their interactions during the duration of their shift. for patrons, this could compromise privacy in reference transactions and in other information seeking activities, as well as capturing other personal interactions that take place in the library setting. it is critical that libraries are transparent about using voice assistant technologies, upfront about the potential privacy harms of these technologies, and abide by “opt-in” rather than “opt-out” frameworks. library workers should consider treating voice assistant records in the same way they have historically treated circulation records, opting to either delete these records or not collect them (meaning, not use voice assistants) at all. unlike circulation records, however, library workers have far less control over the data captured by voice assistants. this data is stored in the cloud on privately owned servers that remain outside of library control and oversight. given the incredibly low bar for federal access to information under the usa patriot act, actively facilitating the collection of patron and staff interactions, particularly without informed consent, should give librarians pause. opt to not adopt in light of the issues raised in this study, library workers need to seriously weigh whether the benefits of using voice assistants in libraries at this point in time outweigh the vast privacy concerns that we have outlined here. as it stands, these technologies are not currently filling a gap in library services that cannot be otherwise met by more traditional service models that carry fewer potential harms for our patron communities. importantly, not all patrons are equally vulnerable to harm or exploitation in these data environments. for instance, there is a wealth of research that demonstrates the multitude of ways that black, indigenous, people of color, lqbtq+, women, and low-income communities are subjected to higher levels of surveillance and data profiling that results in harassment, discrimination, economic penalties, and legal persecution.30 as the current national political landscape is aflame in protests against police violence and anti-black racism, it is important to identify surveillance technologies as policing technologies. libraries need to consider that these tools, as extensions of policing data networks, may directly endanger, particularly, black, latinx, and indigenous people who are already subjected to over-policing. in this sense, concerns about patron data privacy are high-stakes and are deeply linked to the professional core value of social responsibility.31 libraries should consider not using voice assistants until key data privacy concerns are addressed, more robust data protections are in place at a federal level, and the blanket authority for federal agencies and law enforcement to compel user data is revoked. this is not a technophobic stance. on the contrary, we are suggesting that library workers could serve an important role as privacy advocates, which includes critically evaluating the role of emerging technologies in their communities on behalf of public interest. a key part of this must include the library profession taking responsibility for the use of surveillance technologies in their institutions since these technologies are deeply implicated in the policing of disenfranchised communities by state and federal authorities. information technology and libraries december 2020 alexa, are you listening? | sweeney and davis 14 conclusion we view this study as a modest starting point for mapping some of the many privacy issues associated with voice assistant use in library services and programming and hope it points a way forward for future research. future research might address specific case studies of voice assistant use in libraries, data mapping of patron data through third-party library services, use and privacy issues across different institution types, patron digital literacies with voice assistants, and library policies for smart technologies more generally. plural and diverse vantage points are needed to understand the potential impacts of these technologies across different community types. such research is critical for developing best practices, guidelines, policies, and education opportunities for voice assistant use (and other smart technologies) that prioritize patron privacy and confidentiality. the use of voice assistants in libraries raises questions about the responsibility of libraries and librarians to actively engage patron data privacy concerns when considering integrating these technologies into services and programming. indeed, we encourage library workers to consider informed non-adoption of these technologies as a socially responsible professional stance until the key issues we have outlined are addressed. while it is, of course, important for library workers to remain current and innovative in their services, it is also paramount that patron privacy (as a function of safety) stays at the forefront of library services. in other words, it is the responsibility of library workers to anticipate potential privacy issues associated with emerging technologies, rather than treating privacy as a secondary concern to technology adoption. there are tremendous opportunities for library workers to lead the data privacy charge—in collaboration with community stakeholders—in pursuit of privacy-centered library services that are accountable to community members, particularly those who are mostly likely to be harmed by these technologies. information technology and libraries december 2020 alexa, are you listening?

literacy surveilling patrons and staff opt to not adopt conclusion appendix a: survey instrument endnotes 226 technical communications reports-library projects and activities light-pen technology at the university of south carolina-the south carolina circulation system for some years at the university of south carolina studies have been underway to perfect a computer-based circulation system, and every avenue of input has been explored. about three years ago the new light-pen inventory control system which was being developed for use in the retail trade became known to the library. this device, using a light-readable label about one inch square in size, seemed to be a far better input device for an inventory control system utilizing identification cards and books than the traditional punched card. mter as much research as could be done in such a new field, the library staff examined light-pen systems marketed by ncr, checkpointplessey, and the monarch marking system, a subsidiary of pitney-bowes. all of these systems were similar in technology but the hardware and interest of the companies varied. monarch and plessey were very interested and willing to cooperate with libraries. plessey (through checkpoint) has developed and is marketing a library circulation system. at carolina the decision was made to develop an in-house batch system using the monarch light-pen and its technology coupled to a digital equipment corporation pdpll/ 10, 16k, dual dectape system. the basis for the functioning of the system is the light-pen stations at the circulation desk where the books are charged and discharged by running the light-pen rapidly over the light-readable label on the patron's id card and the label in the front inside cover of the book. one quick pass over the id card sets the system, followed by a pass over each book label in succession. at present the library has three light-pen stations and anticipates adding a fourth, which will be sufficient for meeting all of the main library's needs for the foreseeable future. the light-pen control boxes were constructed on campus. they turn the system on, and have message lights, trouble li:ghts, and charge points up to five different due dates. any number of light-pen stations can be attached. a hazeltine 2000 crt is used to show all transactions on the screen as they occur and to serve as the system console. a decwriter, used as a line printer, insures a backup system and gives a printout of transactions. the decwriter was selected because its thirty cps speed is adequate, it is highly reliable, and the price is right. the pdpll is used as a batch controller. it does not convert the label data to human-readable data; this is done at the central computer center. each night after the circulation desk closes, a telephone link is made to the university's central computer and the day's scanned data are pumped into the big computer. while the system is batch design, it incorporates the features of an on-line system without the high cost. if a patron inquires about an item, a glance at the updated patron report and/ or an inquiry into the current activity file through the system console can answer questions on the location of all books in the system. unlike some systems, this one has not required that the lfbrary change its hours of operation or data input. when the library opens in the morning, all reports are distributed. the library gets its in-process, or charge, file, in clear text without borrower information for use by patrons to see which books are charged out. complete circulation files with borrower information are furnished to the circulation staff on com fiche. a total of 10,335 charge records is on each four-bysix-inch fiche. the record includes patron name, status, and social security number, call number of the book, item number, date checked out, date due, author, and title. in addition, there is a field for charging to graduate carrels within the library. notices are periodically written for overdue books and there is an indication in the charge file showing how many notices have been sent. personal reserves or holds can be placed on a book by simply keying the book number into the crt. when a book is returned, a message light on the controller lights so that the staff member will know that the book has a hold on it. similar procedures will put a "hold" on any borrower whom the library needs to reach. the printouts are generally by call number; however, it is possible to get lists of all books by borrower, or in other formats. statistics are obtainable in almost any configuration, including number of books checked out to different categories of borrowers, by individual title, etc. the total cost for the hardware in this system was $38,381.04. maintenance contracts, telephone charges, and miscellaneous operational costs add up to about $357.04 monthly. labels cost $1.70 per thousand. the total cost of the system amortized over a five-year period is no more than $975.00 per month. mter that the only continuing costs will be maintenance contracts and labels. additional light-pen stations can be added in the same building for about $1,200 each. light-pen stations can be added in branch libraries for about $2,400 each. not included in the cost figures is central computer time, which is held to a minimum by the batch features and software development. at the university of south carolina computer services are not charged to the individual department but are treated as a campus-wide service. all of the com fiche is produced on the campus. the entire project was developed and put into operation between april 1973 technical communications 227 and january 1974. the first books were officially charged out on january 15, 1974 and the system has been in continuous operation since then. needless to say, problems of a special nature had to be solved, for example, issuing id cards with light-readable labels to 20,000 students in two days, acquiring labels which are permanent for the books, constructing the control boxes which are unique, and solving the usual telephone and computer difficulties. suffice it to say, the entire project was planned and became operational in less than eight months without employing additional staff. although the system is still being refined, the performance has been spectacular.-kenneth f. toombs, di1'ecto1' of librm·ies, unive1'sity of south cm·olina. public access cable tv information center at new york public library the new york public library (nypl), recognizing public access cable television as an important social tool, has assembled in the mid-manhattan library one of the most extensive collections, and possibly the first, on the subject. noncommercial public access television has been characterized as a people-oriented television system that can respond to and reflect society in terms of culture, language, history, experience, and race. the collection is designed for readers seeking information on all aspects of pubhe access cable tv, both practical and theoretical, with a significant portion devoted to television as a community tool. the mid-manhattan collection includes books, pamphlets, periodicals, and microforms. related materials are also collected to document television activities of programming intentions similar to public access tv. it is hoped that the mid-manhattan project will provide a prototype for other libraries beginning collections of public access cable tv. the collection's book materials emphasize three main areas of interest: programming and the audience, the educational potential of public access television, and legislative controls. pamphlet materials in"' :i: '" : ~ i '" ,, :i!

bibliographies, and other current topics, and are accessible through a vertical file index. the subject headings in the file reflect the "rule of probable associ:ation" whereby the first meaningful word (after the assumed word television) is used. if the reader knows what he wants, aided by cross-reference system, he can easily identify the proper subject file. the collection also includes periodical indexes leading to a wide variety of journal articles on different aspects of video. the eric (educational resources information center) microfiche series is available from 1971 to date and includes much published and unpublished research. a special feature of the collection is the card file which lists hard-to-find information concerning organizations, associations, and periodicals in the field. such commercial groups as video cassette manufacturers as well as alternative groups making tapes can all be located in the file. contact: richard hecht, history and social science

the extension of library services to sparsely populated regions of the rocky mountain and northern plains states. the project has been awarded "designated user" status on the communications technology satellite to be launched by nasa in late 1975. salinet is one of the first attempts to experiment in delivering library services via satellite. a group meeting in denver described plans to use the world's most powerful communications satellite as an extension of local library resources for residents of twelve mountain and plains states. the national space agency, the multistate federation of rocky mountain states, and several library oriented groups and agencies serving the area will pool their expertise and resources in the program, vvhich will begin planning late this year. the library information and development program is a new passenger on the educational satellite which will demonstrate new means of helping to teach residents of far-flung portions of the rocky mountain states and assist them in their information needs during a hvo-year period beginning next fall. four interests are represented in the library oriented project, which bears the acronym of salinet -satellite library information network. the university of denver graduate school of librarianship, the university of kansas libraries, the wyoming state library, and natrona county (wyoming) library are the principals in the consortium. each institution is responsible for certain portions of the library program, which will benefit both libraries and their patrons in the mountain and plains states. dr. margaret knox goggin, dean of the du graduate school of librarianship, is principal investigator on the library program. her co-workers representing other members of the consortium include kenneth e. dowlin, director of natrona county library, casper, wyoming; william williams, wyoming state librarian; and robert malinowsky, assistant director for public service, education, and statistics at the university of kansas libraries. also taking part in the salinet program are the bibliographical center for research, rocky mountain region, inc.; the federation of rocky mountain states; and the mountain-plains library association. these groups will assist with programming, broadcast, and engineering requirements, utilization, and research. the proposed program will utilize fiftysix satellite ground stations which will be in place as part of the federation of rocky mountain states' satellite technology demonstrations. twenty participating libraries in the states of north dakota, south dakota, nebraska, and kansas will 230 1 ournal of library automation vol. 7 i 3 september 197 4 the student as "physician" has selected in managing the case. the learning center offers this and other kinds of audiovisual programs designed to enhance textbook and classroom learning. computers, video cassettes, slide projectors, and models enable the student to experience close up and at his or her own speed areas of medicine that often cannot he presented as well in lectures or textbooks. in addition to the audiovisual materials, the learning center provides students with periodicals, lecture notes, and reference texts. students can watch dissections, see examples of blood cell abnormalities, hear the sounds of healthy and defective heartbeats, and examine oversize plastic models of the brain, the heart, and other parts of the human anatomy. and, with the computer learning programs, the students can participate in a case and make choices to guide its outcome. medical students learning about iron metabolism last year were split into two groups by their instructor so that half attended traditional classroom lectures and half learned the unit from the computer. final examinations showed no difference between the two groups, according to their teacher, dr. james mcarthur, formerly associate professor of medicine. the students preferred human teachers in small group tutorial sections for this unit, mcarthur said, but generally they were in favor of computer instruction. mcarthur, now assistant director of the health sciences learning resources center at the university of washington in seattle, said that the crowd of students usually found at the learning center is an indication of its success. announcements resolution whereas, the american library association is the chief advocate for librarians and laymen seeking to provide citizens of the united states with the highest quality library and information service, and whereas, a major effort will be required of this association and of all supporters of libraries in the next few years as the country's leaders determine longrange national positions in such matters as copyright, intellectual freedom, federal support of libraries, and a national plan for libraries and information services, and whereas, the effectiveness of this effort will depend on the concerted effort of all those concerned with library service, including library users, citizens groups, government officials and librarians themselves from all aspects and ranks of the profession; therefore let it be resolved that all the committees, chapters and divisions of the american library association take definite steps to increase mutual efforts within the association and with other associations seeking ways to strengthen the common effort toward the provision of quality library service to all people. and let it be further resolved that chapter councilors, division officers, the legislation assembly and chairpersons of committees and round tables, affiliated organizations and related groups transmit this resolution to members of their respective units. adopted by the ala legislation committee on july

communications by telephone a lfghtweight communications system about the size of a suitcase is now being introduced that can take the travel-and the cost-out of meetings. the new solid state system is the darome edu-com, a portable self-contained communications unit with four microphones, that uses regular telephone lines. edu-com enables groups of people in different places across the country to confer together as easily as if they were all in the same room. the cost of a onehour meeting with participants located coast-to-coast is a few hundred dollars. manufactured by darome, inc., of harvard, illinois, makers of modular sound systems equipment, the edu-com unit plugs into an inexpensive, standard telephone coupler, a device supplied by the telephone company. the number of locations that can be included in a darome edu-com conference is practically unlimited. to participate, each location need only be equipped with a darome unit and a telephone coupler. then, rather than having just one meeting at a time, it is possible to hold any number of meetings in any number of places at the same time. before an edu-com session begins, the organizer of the meeting telephones a special conference call telephone operator and gives the names, locations, and telephone numbers of the groups to be reached and the time of the meeting. charges begin only when all locations have been tied together by the operator and the conference is ready to start. the rate for the darome edu-com meetings is much lower than for direct dialing the places individually. the rate is equal to the cost of calling only the farthest city participating in the conference. for example, a one-hour meeting that originates in chicago and includes groups of people who participate in new york, newark, huntington, greensboro, atlanta, orlando, detroit, denver, and san diego would cost $280. 236 journal of library automation vol. 7/3 september 1974 the wall street journal and banon's magazine. anthony a. barnett, senior vice-president of bunker ramo, said test installations in five stockbrokerage firms over the past month "have allowed us to shake down the system and prepare for nationwide marketing." mr. barnett said fifty of the news retrieval systems were sold before formal introduction. "we're encouraged by the marketing prospects among stockbrokerage firms and financial institutions but believe the market among corporations may have even greater potential," he added. the news retrieval system permits instantaneous recall of stories on 6,000 companies listed on the new york and american stock exchanges and traded over-thecounter. users also are able to retrieve news of twenty-five industry groups, fifteen government agencies, and several general categories. mr. barnett said that at the outset customers will be able to recall from the ffie any story that has appeared in the last three months. dj news-recall was developed as a joint venture by bunker ramo and dow jones, which publishes the wall stmet joumal, barron's, and the dow jones news service. the joint venture, dow jones-bunker ramo news retrieval service inc., in turn will market the data base to distributors for resale. bunker ramo's information systems division is the charter distributor for dj news-recall. mr. barnett said the basic charge for dj news-recall to users of bunker ramo's system 7 will be $175 a month per office ·plus $25 for each video terminal having access to the news retrieval service. on-line access to the compendex data base engineering index, inc., announces the availability of its computer-readable data base, compendex, through on-line access. two organizations are currently providing this di'rect mode of bibliographic search: lockheed information systems and system development corporation. using the latest in data communications services, users requiring access to the compendex files may interact with the system via their own in-house terminal, thus providing the convenience and speed of "on-demand" searches. compendex is the machine-readable version of ei's monthly and provides abstracts/bibliographic citations covering worldwide developments in all fields of engineering. both s.d.c. and lockheed, utilizing the most modern system technology, afford the user the opportunity to maintain an actual "dialog" with major bases. this is done without imposing an overly complicated or difficult command language on those addressing the system. on-line access now adds a new dimension to those requiring searches of the ei data base. for further information interested individuals and organizations may contact: lockheed information service, 3251 hanover st., palo alto, ca 94304;

"regardless of the media information companies and other publishers currently use in delivering information," iia presi'dent, paul g. zurkowski, said, "competition and rising costs are forcing them into consideration of alternative methods. iia member companies will be able to focus their energies most effectively on the industry-wide problems through these new committees." micropublishing committee chairman, henry powell, bell & howell, bethesda, at a recent meeting of the committee spelled out several areas of concern to micropublishers which will be the subject of committee action: 1. how can micropublishers protect their investment from unfair competition of unscrupulous competitors who misappropriate the micropublishers' work product and market essentially "reprinted" versions of the original microfilm. 2. library relations. joint library-industry steps toward mutual understanding and cooperation. 3. z-39 standards committee recommended standards covering what

automated news clipping, indexing and retrieval system (ancirs) image systems, inc. of culver city, california, has developed an automated system for the indexing and retrieval of news clippings. while ancirs (pronounced answers) is geared for use in the newspaper library, terminals located at remote sites provide access to the system for business, industry, education, and law enforcement and other government agencies. the microfiche terminals, whfch are controlled by a minicomputer, are each capable of storing 325,000 clippings and 1 million lines of index and search terms. ancirs has a capacity in excess of 1.25 million listings. access to a page of index hstings or to the full text of any clipping requires less than four seconds. paper copy of any or all of the selected clippings can be produced at the terminal at the touch of a button. multiple terminals can share the same minicomputer. a unique off-line/ on-line indexing system generates subject term lists from story headlines and other key words, names, and places in the story as selected by the indexer. when indexing a story, the indexer keys in the first letters of the subject terms to be assigned. this causes the terms currently in use to be displayed at the terminal, allowing the indexer to automatically assign the appropriate terms to the story being indexed. if the term is technical communications 235 not already in use it may be entered by completing the typing of the term. after new terms have been entered and old terms assigned, a magnetic tape is produced for the off-line program. the off-line program prepares three lists for computer output to microfiche: 1. headlines permuted by the key words in each headline interleaved with subject terms selected from the stories. 2. a category list by classification and subclass. 3. each story headline in date order. to perform a search, the user keys i'n the first few letters of the search term. this causes the appropriate portion of list one to be displayed. each item on the page has a line number. keying the line number ( s) selects the desired term ( s) and causes the most recent clipping to be displayed. if the selected term is too general, i.e., a category heading, the appropriate portion of hst two is automatically displayed so that a more precise selection may be made. the selection in this instance is also made by entering the line number(s) of the desired term(s). these selections may be combined logically with other selections to further narrow the search. once the terms have been selected and the most recent story i's displayed it is then possible to page back through previous related stories. the hard copy of any story can be requested at any time and is produced by the unit in ten seconds. ancirs' low cost makes it the ideal tool for researchers and decision makers who must have at their fingertips complete facts on world, national, and local events. machine-readable data bases news retrieval service

procedure this procedure is geared to handle both reactive (originating from the outside) and initiative (originating from within ala) standards proposals to provide recommendations to ala's representatives on existing, recognized standards organizations. to enter the procedure for an initiative standards proposal you must complete an "initiative standards proposal" using the outline which follows: initiative standard proposal outlinethe following outline and forms are designed to facilitate review by both the isad committee on technical standards for library automation (tesla) and the membership of initiative standards requirements and to expedite the handling of the initiative standard proposal through the procedure. since the outline will be used for the review process, it is to be followed explicitly. where an initiative standard requirement does not require the use of a specific outline entry, the entry heading is to be used followed by the words "not applicable" (e.g., where no standards exist which relate to the proposal, this is indicated by: vi. existing standards. not applicable). note that the parenthetical statements following most of the outline entry

tesla will insure that standards proposals are drawn to the attention of the applicable american library association division or committee. thus, internal review usually will proceed concurrently with membership review. from the review and the reactor ballot tesla will prepare a "majority recommendation" and a "minority report" on each standards proposal. the majority recommendation and "minority report" so developed will then be transmitted to the originator, and to the official american library association representative on the appropriate standards organization where it should prove a source of guidance as official votes are cast. in addition, the status of each standards proposal will be reported by tesla in jola-tc via the standards scoreboard. the committee (tesla) itself will be nonpartisan with regard to the proposals handled by it. however, the committee does reserve the right to reject proposals which after review are not found to relate to library automation. an

changed the concept of media literacy and people’s habits of news consumption. while online news is faster, easier, comparatively cheaper, and offers convenience in terms of people's access to information, it speeds up the dissemination of fake news. due to the free production and consumption of large amounts of data, fact-checking systems powered by human efforts are not enough to question the credibility of the information provided, or to prevent its rapid dissemination like a virus. libraries, long known as sources of trusted information, are facing challenges caused by misinformation as mentioned in studies about fake news and libraries.1 considering that libraries are undergoing digitization processes all over the world and are providing digital media to their users, it is very likely that unverified digital content will be served by world’s libraries. the solution is to develop automated mechanisms that can check the credibility of digital content served in libraries without manual validation. for this purpose, we developed an automated fake news detection system based on turkish digital news content. our approach can be modified for any other language if there is labelled training material. this model can be integrated into libraries’ digital systems to label served news content as potentially fake whenever necessary, preventing uncontrolled falsehood dissemination via libraries. introduction collins dictionary which chose the term “fake news” as the “word of the year 2017,” describes news as the actual and objective presentation of a current event, information, or situation that is published in newspapers and broadcast on radio, television, or online.2 we are in an era where everything goes online, and news is not an exception. many people today prefer to read their daily news online, because it is a cost-effective and convenient way to remain up to date. although this convenience has lucrative benefits for society, it can also have harmful side effects. having access to news from multiple sources, anytime, anywhere has become an irresistible part of our daily routines. however, some of these sources may provide unverified content which can easily be delivered right to your mobile device. most importantly, potential fake news content delivered by these sources may mislead society and cause social disturbances such as triggering violence against ethnic minorities and refugees, causing unnecessary fear related to health issues, or even sometimes result in crisis, devastating riots and strikes. not having a steady definition compared to news, fake news is often defined according to the data used or the limited perspective of the study in the literature. for example; difranzo and gloriagarcia defined the fake news as “false news stories that are packaged and published as if they were genuine.”3 on the other hand, guess et al. see the term as “a new form of political misinformation” within the domain of politics, whereas mustafaraj is more direct and defines it as mailto:umertoglu@hacettepe.edu.tr mailto:bgenc@cs.hacettepe.edu.tr information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 2 “lies presented as news.”4 a comprehensive list of 12 definitions can be found in egelhofer and lecheler.5 in simplified terms, news which is created to deceive or mislead readers can be called fake news. however, the concept of fake news is a quite broad one that needs to be specified meticulously. fake news is created for many purposes and emerges in many different types. having an interwoven structure, most of these types are shown in figure 1. although, it is not easy to cluster these types into separate groups, they can be categorized according to the information quality or based on the intention as it is created to deceive deliberately or not, as rashkin et al. did.6 we propose the following classification where the two dimensions represent the potential impact and the speed of propagation. figure 1. the volatile distribution of the fake news types (clustered in four regions: sr, sr, sr, sr) with respect to two dimensions: speed of propagation and potential impact. the four regions visualized are clustered according to their dangerousness. first of all, it should be noted that to order types of fake news in a stable precision is quite a challenging task. the variations within the field highly depend on dynamic factors such as timespan, actors, and echochamber effect. hence, this figure should be considered as a clustering effort. there are possible intersecting areas of types within the regions. we will now give examples for two regions, “sr” and “sr.” for example, the sr grouping shows characteristics of high-risk levels and fast dissemination. this includes varieties of fake news such as propaganda, manipulation, misinformation, hate news, information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 3 provocative news, etc. we usually encounter this in the domain of politics. this kind of news may cause critical and nonrecoverable results in politics, the economy, etc., in a short period of time. the rise of the term fake news itself can also be attributed to this kind of news. on the other hand, the relatively less severe group (sr) of fake news, comprising of satire, hoax, click-bait, etc., has low-risk levels and a slow speed of dissemination. a frequently used type of this group, click-bait, is a sensational headline or link that urges the reader to click on a post, link, article, image, or video. these kinds of news have a repetitive style. it can be said that readers become aware of falsehood after experiencing a few times. so, risk level is lower, and dissemination is slower. vosoughi et al. stated the assumption that “falsehood diffuses significantly farther, faster, deeper, and more broadly than the truth.”7 so indeed, just one piece of fake news may affect many more people than thousands of true news items do because of the dramatic circulation of fake news. in their recent survey about fake news, zhou and zafarani highlighted that fake news is a major concern for many different research disciplines especially information technologies. 8 being a trusted source of information for a long time, libraries will play an important role in fighting against fake news problem. kattimani et al. claims that the modern librarian must be equipped with necessary digital skills and tools to handle both printed collections and newly emerging digital resources.9 similarly, we foresee that digital libraries, which can be defined as collections of digital content licensed and maintained by libraries, can be a part of the solution as an authority service with a collective effort. connaway et al. point to the key role of information professionals such as librarians, archivists, journalists, and information architects in helping society use the products and services related to news in a convenient way. 10 as libraries all over the world are transitioning into digital content delivery services, they should implement mechanisms to avoid fake and misleading content being disseminated through them under the guidance of information professionals. to lay out proper future directions for the solution strategy, a clear understanding of interaction between library and information science (lis) community and fake news must be addressed. sullivan states that the lis community has been affected deeply in the aftermath of the 2016 us presidential elections.11 moreover, he quotes many other scientists, emphasizing libraries’ and librarians’ role in the fight against fake news. for example, finley et al. say that libraries are the direct antithesis of fake news, the american library association (ala) called fake news an anathema to the ethics of librarianship in 2017, rochlin emphasizes the role of librarians in this fight, and talks about the need to adopt fake news as a central concern in librarianship and many other researchers name librarians in the front lines of the fight against fake news.12 today, the struggle to detect fake news and prevent their spread is so popular that competitions are being organized (e.g., http://www.fakenewschallenge.org/) and conferences are being held (e.g., bobcatsss 2020). the struggle against fake news can be classified under three main venues: • reader awareness • fact-checking organizations and websites • automated detection systems the first item requires awareness of individuals against fake news and a collective conscience within the society against spreading fake news. to this end, visual and textual checklists, frameworks, and guidance lists are being published by official organizations, such as ifla’s13 http://www.fakenewschallenge.org/ information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 4 (international federation of library associations) infographic which contains eight steps to spot fake news. the radar framework and the currency, relevance, authority, accuracy, and purpose (craap) test are some of the efforts trying to increase reader-awareness of fake news.14 unfortunately, due to the nature of fake news and the clever way they are created triggering people’s hunger to spread sensational information, it is very difficult to achieve full control via this strategy. some studies explicitly showed that humans are prone to get confused when it comes to spotting lies or deciding whether a news item is fake or not.15 furthermore, people often overlook facts that conflict with their current belief, especially in politics and controversial social issues.16 the second strategy focuses on third-party manually driven systems for checking and labelling content as fake or valid. recently, we have seen many examples of offline and online organizations trying to work according to this strategy, such as a growing body of fact-checking organizations, start-ups (storyzy, factmata, etc.), and other projects with similar purposes.17 unfortunately, these manually powered systems cannot cope with the huge amounts of digital content being steadily produced. therefore, they focus only on a subset of digital content that they classify as having higher priority. even for this subset of content, their reaction speed is much slower than the fake information’s spread speed. therefore, automated and verified systems emerge as an inevitable last option. the third strategy offers automated fact-checking systems, which once trained, can deliver content labelling at unprecedented speeds. today, many researchers are researching automated solutions and building models with different methodologies.18 notwithstanding the latest studies, there is still a lot to do in the realm of automated fake news detection. automated fact-checking systems will be detailed in the rest of the paper. thanks to the internet, the collections of digital content served by digital libraries can be accessed by a great number of users without distance and time limits. therefore, we propose a solution to the problem by positioning digital libraries as automated fact-checking services, which label digital news content as fake or valid as soon as or before it is served through library systems. the main reason we associate this approach with digital libraries is their access to a wide variety of digital content which can be used to train the proposed mathematical models, as well as their role in the society as the publisher of trusted information. to this end, we develop a mathematical model that is trained using existing news content served by digital libraries, and capable of labelling news content as fake or valid with unprecedented accuracy. the proposed solution uses machine learning techniques with an optimized set of extracted features and annotated labels of existing digital news content. our study mainly contributes (a) a new set of features highly applicable for agglutinative languages, (b) the first hybrid model combining a lexicon/dictionarybased approach with machine learning methods to detect fake news, and (c) a benchmark dataset prepared in turkish for fake news detection. literature review contemporary studies have indicated that social, economic, and political events in recent years, especially after the 2016 us presidential elections, are increasingly associated with the concept of fake news.19 since then, fake news has begun to be used as a tool in many domains. on the other hand, researchers motivated by finding automated solutions started to make use of machine learning, deep learning, hybrid models, and other methodologies for their solutions. https://storyzy.com/ information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 5 although computational deception detection studies applying nlp (natural language processing) operations are not new, textual deception in the context of text-based news is a new topic for the field of journalism.20 accordingly, we believe that there is a hidden body language of news text, which has linguistic clues indicating whether the news is fake or not. thus, lexical, syntactic, semantic, and rhetorical analysis when used with machine learning and deep learning techniques offers encouraging directions. the textual deception spread over a wide spectrum and the studies have utilized many different techniques. there are some prominent studies which took the problem as a binary classification problem utilizing linguistic clues.21 although it is still early to say the linguistic characteristics of fake news are fully understood, research into fake-news detection in english-language texts is relatively advanced compared to that in other languages. in contrast, agglutinative languages such as turkish have been little researched when it comes to fake news detection. agglutinative languages enable the construction of words by adding various morphemes, which means that words that are not practically in use may exist theoretically. for example, “gerek-siz-leş-tir-ebilecek-leri-miz-den-dir,” is a theoretically possible word that means “it is one of the things that we will be able to make redundant,” but it is not a practical one. shu et al. classified the models for the detection of fake news in their study.22 according to this study, the automated approaches can focus on four types of attributes to detect fake news: knowledge based, style based, stance based, or propagation based. among these, it can be said that the most useful approaches are the ones which focus on the textual news content. th e textual content can be studied by an automated process to extract features that can be very helpful in classifying content as fake or valid. many scholars have tried to build models for automatic detection and prediction of fake news using machine learning algorithms, deep learning algorithms, and other techniques. these scholars approach the detection of fake news from many different perspectives and domains. for example, in one of the studies, scientific news and conspiracy news were used.23 in shu et al.’s study based on credibility of news, the headlines were used to determine whether the article was clickbait or not. in another study, reis et al. worked on buzzfeed articles linked to the 2016 us election using machine learning techniques with a supervised learning approach.24 studies which try to detect satire and sarcasm can be attributed to subcategories of fake news detection.25 our observation, in line with the general view, is that satire is not always recognizable and can be misunderstood for real news.26 for this reason, we included satirical news in our dataset. it should be noted that although satire or sarcasm can be classified by automated detection systems, experts should still evaluate the results of the classification. while some scholars used specific models focusing on unique characteristics, some others such as ruchansky et al. proposed hybrid deep models for fake news detection making use of multiple kinds of features such as temporal engagement between users and news articles over time and generated a labelling methodology based on those features.27 in related studies, many features such as automatic extracted features, hand-crafted features, social features, network information, visual features, and some others such as psycholinguistic features, are applied by researchers.28 in this work, we focused on news content features, however the social context features can also be adapted using different tiers such as user activity patterns, information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 6 analysis of user interaction, profile metadata, social network/graph analysis etc. to extract features. we also have some of these features in our data but not having ground truth quantitatively, we avoided using these features. methodology in this section, we present our motivation for this work which we visualized in a framework and named global library and information science (glis_1.0). subsequently, we discuss the construction of the automated detection system as the key element of the glis_1.0 framework. we explain the framework, model, dataset, features, and the techniques used in this section. framework the main structure of the proposed framework is shown in figure 2. this framework consists of highly cohesive but flexible layers. figure 2. the glis_1.0 framework main structure. in the presentation layer one can find the different sources of news that are publicly available. these sources can be accessed directly using their websites or can be searched for via search engines. the news is received by fact-checking organizations which classify them manually, digital libraries which archives and serves them, and automated detection systems (ads) which classify them automatically. digital libraries work together with fact-checking organizations and adss to present clean and valid news to the public. moreover, search engines use digital libraries systems to label their results as fake or valid. information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 7 fact-checking organizations should also benefit from the output of adss, as instead of manually checking heaps of news content, they could now focus on news labeled as potentially fake by an ads. through glis, adss make the life of fact-checking organizations and digital libraries much easier, all the while increasing the quality of news served to the public. considering this is a high-level overview of a structure given in figure 2, there may be many other components, mechanisms, or layers, but the key elements of this structure are automated detection systems and the digital libraries. a critical approach to this framework can be why we need such an authority mechanism. the answer will be quite simple, technological progress is not the only solution. on the contrary, tech giants have already been subject to regulatory scrutiny for how they handle personal information.29 also, their policy related to political ads has been questioned. furthermore, they are often blamed for failing to fight fake news. indeed, there is an urgent need for a global action more than ever. digital libraries are much more than a technological advancement. hence, they should be considered as institutions or services which can be a great authority service to provide news to society since the printed media disappears day by day. the threats caused by fake news are real and dangerous, but only recently have researchers from different disciplines been trying to find possible solutions such as educational, technological, regulatory, or political. digital librarianship can be the intersection of all these solutions for promoting information/media literacy. hence, digital librarianship will make use of many automated detection systems (ads) to serve qualified news. in the following section, we discuss ads in detail. model an overview of our model of automated detection system solution which is very critical for the framework is shown in figure 3. our fake news detection model consists of two phases. first is the language model/lexicon generation and the second is machine learning integration. in this work, we used machine learning algorithms via supervised learning techniques which learn from labeled news data (training) and helps us to predict outcomes for unforeseen news data (test). dataset we collected our data from three sources: • the primary source is the gdelt (global database of events, language and tone) project (https://www.gdeltproject.org/), a massive global news media archive offering free access to news text metadata for researchers worldwide. it can almost be considered a digital library of news in its own right. however, gdelt does not provide the actual news text and only serves processed metadata along with the url of the news item. gdelt normally does not check for the validity of any news items. however, we have only used news from approved news agencies and completely ignored news from local and lesser-known sources to maximize the validity of the news we have automatically obtained through gdelt. moreover, we have post-processed the obtained texts by cross-validating with teyit.org data to clean any potential fake news obtained through gdelt links. https://www.gdeltproject.org/ information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 8 figure 3. integrated fake news detection model with main phases combining language-model based approach with machine learning approach. • the second source is teyit.org which is a fact-checking organization based in turkey, compliant to the principles of ifcn (international fact-checking network) aiming to prevent spreading of false information through online channels. manually analyzing each information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 9 news item, they tag them as fake, true, or uncertain. we used their results to automatically download and label each news text. • lastly, our team collected manually curated and verified fake and valid news obtained from various online sources and named it as mvn (manually verified news). this set includes fake and valid news that we have manually accumulated in time during our studies and that were not overlapping with the news obtained from gdelt and teyit.org sources. we named our dataset trfn. in phase 2, the data is very similar to the one we used in phase 1. however, to see the effectiveness of model, we made modifications to exclude old news before 2017 and added new items from 2019. the news in our dataset span a time frame between 2017– 2019 and are uniformly distributed. table 1 outlines the dataset statistics, namely where the news text comes from, its class (fake or valid), the amount of distinct texts and the corresponding data collection method. it can be seen from the table that most of our valid news come from the gdelt source, whereas teyit.org, a fact-checking organization, contributes only fake news. table 1. trfn dataset summary after cleaning and duplicate removal. dataset class size of processed data collection method gdelt non-fake 82708 automated teyit.org fake 1026 mvn non-fake 1049 manual fake 400 all news items were processed through zemberek (http://code.google.com/p/zemberek), the turkish nlp engine for extracting different morphological properties of words within texts. after this processing phase, all obtained features were converted into tabular format and made available for future studies. this dataset is now available for scholarly studies upon request. in a study of this nature, the verifiability of the data used is important. as we have already mentioned, most of the data we used comes from verified sources such as mainstream news agencies accessed through gdelt and teyit.org archives which are verified by teyit.org staff. all data used in training the mathematical models which are to be explained in the rest of the paper are either directly or indirectly verified. another important issue was generalizability of the dataset, which determines whether the results of the study are only applicable to specific domains or to all available domains. although focusing on a specific news domain would clearly improve our accuracies, we preferred to work in the general domain and included news from all specific domains. the distribution of domains in our dataset is visualized in figure 4. this distribution closely matches the distribution one would experience reading daily news in turkey. hence, we have no domain

(scitechenvwetnatlife = science, technology, environment, weather, nature, life. educulturearttourism = education, culture, art, tourism.) moreover, we obtained highly correlated evidence showing syntactic similarities with the other nlp studies in turkish during the exploratory data analysis. for example, the results of a study by zemberek developers (http://zembereknlp.blogspot.com/2006/11/kelime-istatistikleri.html) to find the most common words in turkish experimented with over five million words is compatible with most common words in our corpus. this evidence can be attributed to representability of our dataset. the last issue worth discussing is the imbalanced nature of the dataset. an imbalanced dataset occurs in a binary classification study when the frequency of one of the classes dominates the frequency of the other class in the dataset. in our dataset, the amount of fake news is highly surpassed by the amount of valid news. this generally results in difficulties in applying conventional machine learning methods to the dataset. however, it is a frequently observed phenomenon due to the disparity of variable classes in these kinds of problems in real world. to avoid potential problems due to the imbalanced nature of the dataset, we used smote (synthetic http://zembereknlp.blogspot.com/2006/11/kelime-istatistikleri.html information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 11 minority over-sampling technique) which is an over-sampling method.30 it creates synthetic samples of the minority class that are relatively close in the feature space to the existing observations of the minority class. features in this study, we discarded some features because of their relatively low impact on overall performance during the exploratory data analysis and subsequently in the training phase. the most effective features we decided on are shown in table 2. table 2. main features features group definition nrootscore language model features the news score calculated according to the root model nrawscore the news score calculated according to the raw model spellerrorscore extracted features spell errors per sentences complexityscore the score of the complexity/readibility of the news source labels the url or identifier of the news maincategory the category of the news newssite the unique address of the news the language model features nrootscore and nrawscore are features that we have borrowed from our earlier study on fake news detection.31 in that study, we focused on constructing a fake news dictionary/lexicon based on different morphological segments of the words used in news texts. these two scores were found to be the most successful ones in determining the fakeness/validity of a news text, one considering the raw form of the words, the other considering the root form. the extracted features are complexityscore and spellerrorscore. complexityscore basically represents the readability of the text. studies for determining a good readability metric exist for the turkish language.32 we used a modified version of the gunnig-fog metric, which is based on word length and sentence length.33 since turkish is an agglutinative language, we used word length instead of using the syllable count. we also made some modifications to normalize the scores. the average number of syllables per word syllable in turkish is 2.6, so we defined a word as a long word if it has more than 9 letters.34 for a given news text t, the complexity score (cs) can be computed by equation 1. (1) 𝑇𝐶𝑆 = ( 𝑊𝑜𝑟𝑑𝑐𝑜𝑢𝑛𝑡 𝑆𝑒𝑛𝑡𝑒𝑛𝑐𝑒𝑠𝑐𝑜𝑢𝑛𝑡 + 𝐿𝑜𝑛𝑔𝑊𝑜𝑟𝑑𝑐𝑜𝑢𝑛𝑡∗100 𝑊𝑜𝑟𝑑𝑐𝑜𝑢𝑛𝑡 10 ) the second extracted feature is spellerrorscore. we foresee that there may be many more errors in fake news than in valid news. we calculated the spell error counts making use of turkish spellchecker class of zemberek. due to the text length of news varies, we calculate the ratio information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 12 according to the sentences. for a given news text t, se (spell error score) is calculated as shown in equation 2. (2) 𝑇𝑆𝐸 = ( 𝑆𝑝𝑒𝑙𝑙𝐸𝑟𝑟𝑜𝑟𝐶𝑜𝑢𝑛𝑡 𝑆𝑒𝑛𝑡𝑒𝑛𝑐𝑒𝑠𝐶𝑜𝑢𝑛𝑡 ) finally, we included the metadata categories source, maincategory, and newssite as additional identifiers for the learning process. then, we combined features extracted from text representation techniques with the features shown in table 2 and trained the model with different classifiers. for text representation, we followed two directions for the experiments. first, we converted text into structured features with bag of words (bow) approach in which text data is represented as the multiset of its words. second, we experimented with n-grams which represents the sequence of n words, in other words splitting text into chunks of size n-words. in the (bow) model, documents in trfn are represented as a collection of words, ignoring grammar and even word order, but preserving multiplicity. in a classic bow approach, each document can be represented as a fixed-length vector with length equal to the vocabulary size. this means each dimension of this vector corresponds to the occurrence of a word in a news item. we customized the generic approach by reducing variable-length documents to fixed-length vectors to be able to use with varying lengths with many machine learning models. information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 13 figure 5. an overview of bow (bag of word) approach. because we ignore the word order, we reduced fixed length of counts as histograms as seen in figure 5. assuming n is the number of news documents and w is the number of possible words in the corpus, it should be noted that in n*w count matrix, n is generally large but infrequent, because we have many news documents, but most words do not occur in any given document causing rareness of a term/word which is a drawback for the approach. therefore, we modified the model to compensate the rarity problem by weighting the terms using tf-idf measure which evaluates how important a word is to a document in a collection. the other technique we used, n-gram model is the generic term for a string of words in computational linguistics, and it is extensively used in text mining and nlp tasks. the prefixes that replace the n-part indicate the number of consecutive words in the string. so, a unigram is referred to one word, a bigram is two words, and an n-gram is n words. experimental results and discussion in this section, the experimental process and the results are presented. all experiments are performed using the scikit-learn library. to evaluate the performance of the model and proposed features we employed the precision, recall, f1 score (the harmonic mean of the precision and recall), and accuracy metrics. we did many experiments using different combinations of features. information technology and libraries december 2020 automated fake news detection in the age of digital libraries | mertoğlu and genç 14 several classification models have been trained. these are as follows: k-nearest neighbor, decision trees, gaussian naive bayes, random forest, support vector machine, extratrees classifier, and logistic regression. to be effective, a classifier should be able to correctly classify previously unseen data. to this end, we tuned the parameter values for all the classification models used. then, models were trained and evaluated on trfn dataset using 10-fold cross-validation. in table 3, we present the ultimate best scores of the proposed model. the results are highly motivating to exemplify how useful automated detection systems can be as a key component of the integrated solution framework in figure 2. we compared the algorithms with three ultimate feature sets for having respectively consistent results to the other feature set combinations. set1 stands for bigram+fopt (optimized features), set2 stands for bowmodified+ fopt and set3 stands for unigram+bigram+fopt. the results show that there is a relative consistency in terms of performance across the models. in almost all models, the combination of unigram+bigram and optimized features sets (fopt) gives better results than the other combinations. the extratree classifier model is chosen as the best due to its higher performance. this model is also known as extremely randomized trees classifier which is a type of ensemble learning technique aggregating the results of multiple decision trees collected in a “forest” to output its classification result. it is very similar to random forest classifier and only differs in the manner of construction of the decision trees. so, we can also see closer results between these two classifiers. table 3. results. evaluation results of all combinations of features and classification models.

neural networks with deep learning methodology can also be used according to the data, language of news and the news features related with both social context and news content. conclusion and future work in this study we presented a novel framework which offers a practical architecture of an integrated system for identifying fake news. we have tried to illustrate how digital libraries can be a service authority to promote media literacy and fight against fake news. because librarians are trained to critically analyze information sources, their contributions to our proposed model are critical. accordingly, we see this work as an encouraging effort for the next collaborative studies among the communities of lis and cs (computer science). we think that there is an immediate need for lis professionals to participate and contribute to automated solutions that can help detecting inaccurate and unverified information. in the same manner, we believe the collaboration of lis professionals, computer scientists, fact-checking organizations, and pioneering technology platforms is the key to provide qualified news within a real-time framework to promote information literacy. moreover, we put the reader at the core of the framework as the feed reader position while consuming news. in terms of automated detection systems, we proposed a fake news detection model in tegration of dictionary-based approach and machine learning techniques offering optimized feature sets applicable to agglutinative languages. we comparatively analyzed the findings with several classification models. we demonstrated that machine learning algorithms when used together with dictionary-based findings yield high scores both for precision and recall. consequently, we believe once operational in the field, proposed workflow can be extended in the future to support other news elements such as photographs and videos. with the help of social network analysis (sna) it may be possible to stop or slow down the spread of fake news as it emerges. during all the experiments we did, this work also highlighted several tasks as future research directions such as: • the studies can be deepened to mathematically categorize the fake news types and the dissemination characteristics of each type can be analyzed. • the workflow has the potential to provide an automated verification platform for all news content existing in digital libraries to promote media literacy. endnotes 1 m. connor sullivan, “why librarians can’t fight fake news,” journal of librarianship and information science 51, no. 4

features experimental results and discussion conclusion and future work endnotes 76 information technology and libraries | june 2010 in this paper we discuss the design space of methods for integrating information from web services into websites. we focus primarily on client-side mash-ups, in which code running in the user’s browser contacts web services directly without the assistance of an intermediary server or proxy. to create such mash-ups, we advocate the use of “widgets,” which are easy-to-use, customizable html elements whose use does not require programming knowledge. although the techniques we discuss apply to any web-based information system, we specifically consider how an opac can become both the target of web services integration and also a web service that provides information to be integrated elsewhere. we describe three widget libraries we have developed, which provide access to four web services. these libraries have been deployed by us and others. our contributions are twofold: we give practitioners an insight into the trade-offs surrounding the appropriate choice of mash-up model, and we present the specific designs and use examples of three concrete widget libraries librarians can directly use or adapt. all software described in this paper is available under the lgpl open source license. ■■ background web-based information systems use a client-server architecture in which the server sends html markup to the user’s browser, which then renders this html and displays it to the user. along with html markup, a server may send javascript code that executes in the user’s browser. this javascript code can in turn contact the original server or additional servers and include information obtained from them into the rendered content while it is being displayed. this basic architecture allows for myriad possible design choices and combinations for mash-ups. each design choice has implications to ease of use, customizability, programming requirements, hosting requirements, scalability, latency, and availability. server-side mash-ups in a server-side mash-up design, shown in figure 1, the mash-up server contacts the base server and each source when it receives a request from a client. it combines the information received from the base server and the sources and sends the combined html to the client. server-side mash-up systems that combine base and mash-up servers are also referred to as data mash-up systems. such data mash-up systems typically provide a web-based configuration front-end that allows users to select data sources, specify the manner in which they are combined, and to create a layout for the entire mash-up. godmar back and annette bailey web services and widgets for library information systems as more libraries integrate information from web services to enhance their online public displays, techniques that facilitate this integration are needed. this paper presents a technique for such integration that is based on html widgets. we discuss three example systems (google book classes, tictoclookup, and majax) that implement this technique. these systems can be easily adapted without requiring programming experience or expensive hosting. t o improve the usefulness and quality of their online public access catalogs (opacs), more and more librarians include information from additional sources into their public displays.1 examples of such sources include web services that provide additional bibliographic information, social bookmarking and tagging information, book reviews, alternative sources for bibliographic items, table-of-contents previews, and excerpts. as new web services emerge, librarians quickly integrate them to enhance the quality of their opac displays. conversely, librarians are interested in opening the bibliographic, holdings, and circulation information contained in their opacs for inclusion into other web offerings they or others maintain. for example, by turning their opac into a web service, subject librarians can include up-to-the-minute circulation information in subject or resource guides. similarly, university instructors can use an opac’s metadata records to display citation information ready for import into citation management software on their course pages. the ability to easily create such “mash-up” pages is crucial for increasing the visibility and reach of the digital resources libraries provide. although the technology to use web services to create mash-ups is well known, several practical requirements must be met to facilitate its widespread use. first, any environment providing for such integration should be easy to use, even for librarians with limited programming background. this ease of use must extend to environments that include proprietary systems, such as vendor-provided opacs. second, integration must be seamless and customizable, allowing for local display preferences and flexible styling. third, the setup, hosting, and maintenance of any necessary infrastructure must be low-cost and should maximize the use of already available or freely accessible resources. fourth, performance must be acceptable, both in terms of latency and scalability.2 godmar back (gback@cs.vt.edu) is assistant professor, department of computer science and annette bailey (afbailey@vt.edu) is assistant professor, university libraries, virginia tech university, blacksburg. web services and widgets for library information systems | back and bailey 77 examples of such systems include dapper and yahoo! pipes.3 these systems require very little programming knowledge, but they limit mash-up creators to the functionality supported by a particular system and do not allow the user to leverage the layout and functionality of an existing base server, such as an existing opac. integrating server-side mash-up systems with proprietary opacs as the base server is difficult because the mash-up server must parse the opac’s output before integrating any additional information. moreover, users must now visit—or be redirected to—the url of the mash-up server. although some emerging extensible opac designs provide the ability to include information from external sources directly and easily, most currently deployed systems do not.4 in addition, those mash-up servers that do usually require server-side programming to retrieve and integrate the information coming from the mash-up sources into the page. the availability of software libraries and the use of special purpose markup languages may mitigate this requirement in the future. from a performance scalability point of view, the mash-up server is a bottleneck in server-side mash-ups and therefore must be made large enough to handle the expected load of end-user requests. on the other hand, the caching of data retrieved from mash-up sources is simple to implement in this arrangement because only the mash-up server contacts these sources. such caching reduces the frequency with which requests have to be sent to sources if their data is cacheable, that is, if realtime information is not required. the latency in this design is the sum of the time required for the client to send a request to the mashup server and receive a reply, plus the processing time required by the server, plus the time incurred by sending a request and receiving a reply from the last responding mash-up source. this model assumes that the mash-up server contacts all sources in parallel, or as soon as the server knows that information from a source should be included in a page. the availability of the system depends on the availability of all mash-up sources. if a mash-up source does not respond, the end user must wait until such failure is apparent to the mash-up server via a timeout. finally, because the mash-up server acts as a client to the base and source servers, no additional security considerations apply with respect to which sources may be contacted. there also are no restrictions on the data interchange format used by source servers as long as the mash-up server is able to parse the data returned. client-side mash-ups in a client-side setup, shown in figure 2, the base server sends only a partial website to the client, along with javascript code that instructs the client which other sources of information to contact. when executed in the browser, this javascript code retrieves the information from the mash-up sources directly and completes the mash-up. the primary appeal of client-side mashing is that no mash-up server is required, and thus the url that users visit does not change. consequently, the mash-up server is no longer a bottleneck. equally important, no maintenance is required for this server, which is particularly relevant when libraries use turnkey solutions that restrict administrative access to the machine housing their opac. on the other hand, without a mash-up server, results from mash-up sources can no longer be centrally cached. thus the mash-up sources themselves must be sufficiently figure 1. server-side mash-up construction figure 2. client-side mash-up construction 78 information technology and libraries | june 2010 scalable to handle the expected number of requests. as a load-reducing strategy, mash-up sources can label their results with appropriate expiration times to influence the caching of results in the clients’ browsers. availability is increased because the mash-up degrades gracefully if some of the mash-up sources fail, since the information from the remaining sources can still be displayed to the user. assuming that requests are sent by the client in parallel or as soon as possible, and assuming that each mash-up source responds with similar latency to requests sent by the user’s browser as to requests sent by a mash-up server, the latency for a client-side mash-up is similar to the server-side mash-up. however, unlike in the server-side approach, the page designer has the option to display partial results to the user while some requests are still in progress, or even to delay sending some requests until the user explicitly requests the data by clicking on a link or other element on the page. because client-side mash-ups rely on javascript code to contact web services directly, they are subject to a number of restrictions that stem from the security model governing the execution of javascript code in current browsers. this security model is designed to protect the user from malicious websites that could exploit client-side code and abuse the user’s credentials to retrieve html or xml data from other websites to which a user has access. such malicious code could then relay this potentially sensitive data back to the malicious site. to prevent such attacks, the security model allows the retrieval of html text or xml data only from sites within the same domain as the origin site, a policy commonly known as sameorigin policy. in figure 2, sources a and b come from the same domain as the page the user visits. the restrictions of the same-origin policy can be avoided by using the javascript object notation (json) interchange format.5 because client-side code may retrieve and execute javascript code served from any domain, web services that are not co-located with the origin site can make their results available using json. doing so facilitates their inclusion into any page, independent of the domain from which it is served (see source c in figure 2). many existing web services already provide an option to return data in json format, perhaps along with other formats such as xml. for web services that do not, a proxy server may be required to translate the data coming from the service into json. if the implementation of a proxy server is not feasible, the web service is usable only on pages within the same domain as the website using it. client-side mash-ups lend themselves naturally to enhancing the functionality of existing, proprietary opac systems, particularly when a vendor provides only limited extensibility. because they do not require server-side programming, the absence of a suitable vendor-provided server-side programming interface does not prevent their creation. oftentimes, vendor-provided templates or variables can be suitably adapted to send the necessary html markup and javascript code to the client. the amount of javascript code a librarian needs to write (or copy from a provided example) determines both the likelihood of adoption and the maintainability of a given mash-up creation. the less javascript code there is to write, the larger the group of librarians who feel comfortable trying and adopting a given implementation. the approach of using html widgets hides the use of javascript almost entirely from the mash-up creator. html widgets represent specially composed markup, which will be replaced with information coming from a mash-up source when the page is rendered. because the necessary code is contained in a javascript library, adapters do not need to understand programming to use the information coming from the web service. finally, html widgets are also preferable for javascript-savvy users because they create a layer of abstraction over the complexity and browser dependencies inherent in javascript programming. ■■ the google book classes widget library to illustrate our approach, we present a first example that allows the integration of data obtained from google book search into any website, including opac pages. google book search provides access to google’s database of book metadata and contents. because of the company’s book scanning activities as well as through agreements with publishers, google hosts scanned images of many book jackets as well as partial or even full previews for some books. many libraries are interested in either using the book jackets when displaying opac records or alerting their users if google can provide a partial or full view of an item a user selected in their catalog, or both.6 this service can help users decide whether to borrow the book from the library. the google book search dynamic link api the google book search dynamic link api is a jsonbased web service through which google provides certain metadata for items it has indexed. it can be queried using bibliographic identifiers such as isbn, oclc number, or library of congress control number (lccn). it returns a small set of data that includes the url of a book jacket thumbnail image, the url of a page with bibliographic information, the url of a preview page (if available), as well as information about the extent of any preview and whether the preview viewer can be embedded directly into other pages. table 1 shows the json result returned for an example isbn. web services and widgets for library information systems | back and bailey 79 widgetization to facilitate the easy integration of this service into websites without javascript programming, we developed a widget library. from the adapter’s perspective, the use of these widgets is extremely simple. the adapter places html <span> or <div> tags into the page where they want data from google book search to display. these tags contain an html <title> attribute that acts as an identifier to describe the bibliographic item for which information should be retrieved. it may contain its isbn, oclc number, or lccn. in addition, the tags also contain one or more html <class> attributes to describe which processing should be done with the information retrieved from google to integrate it into the page. these classes can be combined with a list of traditional css classes in the <class> attribute to apply further style and formatting control. examples as an example, consider the following html an adapter may use in a page: <span title=“isbn:0596000278” class=“gbs -thumbnail gbs-link-to-preview”></span> when processed by the google book classes widget library, the class “gbs-thumbnail” instructs the widget to embed a thumbnail image of the book jacket for isbn 0596000278, and “gbs-link-to-preview” provides instructions to wrap the <span> tag in a hyperlink pointing to google’s preview page. the result is as if the server had contacted google’s web service and constructed the html shown in example 1 in table 2, but the mash-up creator does not need to be concerned with the mechanics of contacting google’s service and making the necessary manipulations to the document. example 2 in table 2 demonstrates a second possible use of the widget. in this example, the creator’s intent is to display an image that links to google’s information page if and only if google provides at least a partial preview for the book in question. this goal is accomplished by placing the image inside the span and using style=“display:none” to make the span initially invisible. the span is made visible only if a preview is available at google, displaying the hyperlinked image. the full list of features supported by the google book classes widget library can be found in table 3. integration with legacy opacs the approach described thus far assumes that the mashup creator has sufficient control over the html markup that is sent to the user. this assumption does not always hold if the html is produced by a vendor-provided system, since such systems automatically generate most of the html used to display opac search results or individual bibliographic records. if the opac provides an extension system, such as a facility to embed customized links to external resources, it may be used to generate the necessary html by utilizing variables (e.g., “@#isbn@” for isbn numbers) set by the opac software. if no extension facility exists, accommodations by the widget library are needed to maintain the goal of not requiring any programming on the part of the adapter. we implemented such accommodations to facilitate the use of google book classes within a iii millennium opac.7 we used magic strings such as “isbn:millennium.record” in a table 1. sample request and response for google book search dynamic

search results page. ■■ the tictoclookup widget library the tictocs journal table of contents service is a free online service that allows academic researchers and web services and widgets for library information systems | back and bailey 81 other users to keep up with newly published research by giving them access to thousands of journal tables of contents from multiple publishers.8 the tictocs consortium compiles and maintains a dataset that maps issns and journal titles to rss-feed urls for the journals’ tables of contents. the tictoclookup web service we used the tictocs dataset to create a simple json web service called “tictoclookup” that returns rss-feed urls when queried by issn and, optionally, by journal title. table 4 shows an example query and response. to accommodate different hosting scenarios, we created two implementations of this tictoclookup: a standalone and a cloud-based implementation. the standalone version is implemented as a python web application conformant to the web services gateway interface (wsgi) specification. hosting this version requires access to a web server that supports a wsgicompatible environment, such as apache’s mod_wsgi. the python application reads the tictocs dataset and responds to lookup requests for specific issns. a cron job downloads the most up-to-date version of the dataset periodically. the cloud version of the tictoclookup service is implemented as a google app engine (gae) application. it uses the highly scalable and highly available gae datastore to store tictocs data records. gae applications run on servers located in google’s regional data centers so that requests are handled by a data center geographically close to the requesting client. as of june 2009, google hosting of gae applications is free, which includes a free allotment of several computational resources. for each application, gae allows quotas of up to 1.3 mb requests and the use of up to 10 gb of bandwidth per twenty-fourhour period. although this capacity is sufficient for the purposes of many small and medium-size institutions, additional capacity can be purchased at a small cost. widgetization to facilitate the easy integration of this service into websites without javascript programming, we developed a widget library. like google book classes, this widget library is controlled via html attributes associated with html <span> or <div> tags that are placed into the page where the user decides to display data from the tictoclookup service. the html <title> attribute identifies the journal by its issn or its issn and title. as with google book classes, figure 3. sample use of google book classes in an opac results page table 4. sample request and response for tictocs lookup web service request: http://tictoclookup.appspot.com/0028-0836?title=nature&jsoncallback=process json response: process({ “lastmod”: “wed apr 29 05:42:36 2009”, “records”: [{ “title”: “nature”, “rssfeed”: http://www.nature.com/nature/current_issue/rss }], “issn”: “00280836” }); 82 information technology and libraries | june 2010 the html <class> attribute describes the desired processing, which may contain traditional css classes. example consider the following html an adapter may use in a page: <span style=“display:none” class=“tictoc-link tictoc-preview tictoc-alternate-link” title=“issn:00280836: nature”> click to subscribe to table of contents for this journal </span> when processed by the tictoclookup widget library, the class “tictoc-link” instructs the widget to wrap the span in a link to the rss feed at which the table of content is published, allowing users to subscribe to it. the class “tictoc-preview” associates a tooltip element with the span, which displays the first entries of the feed when the user hovers over the link. we use the google feeds api, another json-based web service, to retrieve a cached copy of the feed. the “tictoc-alternate-link” class places an alternate link into the current document, which in some browsers triggers the display of the rss feed icon figure 4. sample use of tictoclookup classes in the status bar. the <span> element, which is initially invisible, is made visible if and only if the tictoclookup service returns information for the given pair of issn and title. figure 4 provides a screenshot of the display if the user hovers over the link. as with google book classes, the mash-up creator does not need to be concerned with the mechanics of contacting the tictoclookup web service and making the necessary manipulations to the document. table 5 provides a complete overview of the classes tictoclookup supports. integration with legacy opacs similar to the google book classes widget library, we implemented provisions that allow the use of tictoclookup classes on pages over which the mash-up creator has limited control. for instance, specifying a title attribute of “issn:millennium.issnandtitle” harvests the issn and journal title from the iii millennium’s record display page. ■■ majax whereas the widget libraries discussed thus far integrate external web services into an opac display, majax is a widget library that integrates information coming from an opac into other pages, such as resource guides or course displays. majax is designed for use with a iii millennium integrated library system (ils) whose vendor does not provide a web-services interface. the techniques we used, however, extend to other opacs as well. like many table 5. supported tictoclookup classes tictoclookup class meaning tictoc-link tictoc-preview tictoc-embed-n tictoc-alternate-link tictoc-append-title wrap span/div in link to table of contents display tooltip with preview of current entries embed preview of first n entries insert <link rel=“alternate”> into document append the title of the journal to the span/div web services and widgets for library information systems | back and bailey 83 legacy opacs, millennium does not only lack a web-services interface, but lacks any programming interface to the records contained in the system and does not provide access to the database or file system of the machine housing the opac. providing opac data as a web service we implemented two methods to access records from the millennium opac using bibliographic identifiers such as isbn, oclc number, bibliographic record number, and item title. both methods provide access to complete marc records and holdings information, along with locations and real-time availability for each held item. majax extracts this information via screenscraping from the marc record display page. as with all screen-scraping approaches, the code performing the scraping must be updated if the output format provided by the opac changes. in our experience, such changes occur at a frequency of less than once per year. the first method, majax 1, implements screen scraping using javascript code that is contained in a document placed in a directory on the server (/screens), which is normally used for supplementary resources, such as images. this document is included in the target page as a hidden html <iframe> element (see frame b in figure 2). consequently, the same-domain restriction applies to the code residing in it. majax 1 can thus be used only on pages within the same domain—for instance, if the opac is housed at opac.library.university.edu, majax 1 may be used on all pages within *.university.edu (not merely *.library.university.edu). the key advantage of majax 1 is that no additional server is required. the second method, majax 2, uses an intermediary server that retrieves the data from the opac, translates it to json, and returns it to the client. this method, shown in figure 5, returns json data and therefore does not suffer from the same-domain restriction. however, it requires hosting the majax 2 web service. like the tictoclookup web service, we implemented the majax 2 web service using python conformant to wsgi. a single installation can support multiple opacs. widgetization the majax widget library allows the integration of both majax 1 and majax 2 data into websites without javascript programming. the <span> tags function as placeholders, and <title> and <class> attributes describe the desired processing. majax provides a number of “majax classes,” multiple of which can be specified. these classes allow a mash-up creator to insert a large variety of bibliographic information, such as the values of marc fields. classes are also provided to insert fully formatted, ready-to-copy bibliographic references in harvard style, live circulation information, links to the catalog record, links to online versions of the item (if applicable), a ready-to-import ris description of the item, and even images of the book cover. a list of classes majax supports is provided in table 6. examples figure 6 provides an example use of majax widgets. four <span> tags expand into the book cover, a complete harvard-style reference, the valid of a specific marc field (020), and a display of the current availability of the item, wrapped in a link to the catalog record. texts such as “copy is available” shown in figure 6 are localizable. even though there are multiple majax <span> tags that refer to the same isbn, the majax widget library will contact the majax 1 or majax 2 web service only once per identifier, independent of how often it is used in a page. to manage the load, the majax client site library can be configured to not exceed a maximum number of requests per second, per client. all software described in this paper is available under the lgpl open source license. the majax libraries have been used by us and others for about two years. for instance, the “new books” list in our library uses majax 1 to provide circulation information. faculty members at our institution are using majax to enrich their course websites. a number of libraries have adopted majax 1, which is particularly easy to host because no additional server is required. ■■ related work most ilss in use today do not provide suitable web-services interfaces to access either bibliographic information figure 5. architecture of the majax 2 web service 84 information technology and libraries | june 2010 or availability data.9 this shortcoming is addressed by multiple initiatives. the ils discovery interface task force (ils-di) created a set of recommendations that facilitate the integration of discovery interfaces with legacy ilss, but does not define a concrete api.10 related, the iso 20775 holdings standard describes an xml schema to describe the availability of items across systems, but does not describe an api for accessing them.11 many ilss provide a z39.50 interface in addition to their htmlbased web opacs, but z39.50 does not provide standardized holdings and availability.12 nevertheless, there is hope within the community that ils vendors will react to their customers’ needs and provide web-services interfaces that implement these recommendations. the jangle project provides an api and an implementation of the ils-di recommendations through a representations state transfer (rest)–based interface that uses the atom publishing protocol (app).13 jangle can be linked to legacy ilss via connectors. the use of the xml-based app prevents direct access from client-side javascript code, however. in the future, adoption and widespread implementation of the w3c working draft on crossorigin resource sharing may relax the same-origin restriction in a controlled fashion, and thus allow access to app feeds from javascript across domains.14 screen-scraping is a common technique used to overcome the lack of web-services interfaces. for instance, oclc’s worldcat local product obtains access to availability information from legacy ilss in a similar fashion as our majax 2 service.15 whereas the web services used or created in our work exclusively use a rest-based model and return data in json format, interfaces based on soap (formerly simple object access protocol) whose semantics are described by a wsdl specification provide an alternative if access from within client-side javascript code is not required.16 html written by adapter <table width=“340”><tr><td> <span

considered the cases where an opac is either the target of such integration or the source of the information being integrated. we focused on client-side techniques in which each user’s browser contacts web services directly because this approach lends itself to the creation of html widgets. these widgets allow the integration and customization of web services without requiring programming. therefore nonprogrammers can become mash-up creators. we described in detail the functionality and use of several widget libraries and web services we built. table 7 provides a summary of the functionality and hosting requirements for each system discussed. although the specific requirements for each system differ because of their respective nature, all systems are designed to be deployable with minimum effort and resource requirements. this low entry cost, combined with the provision of a high-level, nonprogramming interface, constitute two crucial preconditions for the broad adoption of mash-up techniques in libraries, which in turn has the potential to context objects in pages for processing by client-side extension.20 librarything uses client-side mash-up techniques to incorporate a social tagging service into opac pages.21 although their technique uses a <div> element as a placeholder, it does not allow customization via classes—the changes to the content are encoded in custom-generated javascript code for each library that subscribes to the service. the juice project shares our goal of simplifying the enrichment of opac pages with content from other sources.22 it provides a set of reusable components that is directed at javascript programmers, not librarians. in the computer-science community, multiple emerging projects investigate how to simplify the creation of server-side data mash-ups by end user programmers.23 ■■ conclusion this paper explored the design space of mash-up table 7. summary of features and requirements for the widget

gets used and why it matters paromita biswas and joel marchesoni information technology and libraries | december 2016 19 abstract this paper analyzes usage data from hunter library’s digital collections using google analytics for a period of twenty-seven months from october 2013 through december 2015. the authors consider this data analysis to be important for identifying collections that receive the largest number of visits. we argue this data evaluation is important in terms of better informing decisions for building digital collections that will serve user needs. the authors also study the benefits of harvesting to sites such as the digital public library of america, and they believe this paper will contribute to the literature on google analytics and its use by libraries. introduction hunter library at western carolina university (wcu) has fourteen digital collections hosted in contentdm—a digital collection management system from oclc. users can enter the collections in various ways—through the library’s contentdm landing pages,1 search engines, or sites such as the digital public library of america (dpla) where all the collections are harvested.2 since october 2013, the library has collected usage data from its collections’ websites and from dpla referrals via google analytics. this paper analyzes this usage data covering a period of approximately twenty-seven months from october 2013 through december 2015. the authors consider this data analysis important for identifying collections receiving the largest number of visits, including visits through harvesting sites such as the dpla. the authors argue that such data evaluation is important because it can better inform decisions taken to build collections that will attract users and serve their needs. additionally, this analysis of usage data generated from harvesting sites such as the dpla demonstrates the usefulness of harvesting in increasing digital collections’ usage. lastly, this paper contributes to the broader literature on google analytics and its use by libraries in data analysis. literature review using google analytics to study usage of electronic resources is common; a considerable amount of material exists describing the use of google analytics in marketing and business fields.3 paromita biswas (pbiswas@email.wcu.edu) is metadata librarian and joel marchesoni (jmarch@email.wcu.edu) is technology support analyst, hunter library, western carolina university, cullowhee, north carolina. analyzing digital collections entrances: what gets used and why it matters | biswas and marchesoni | https://doi.org/10.6017/ital.v35i4.9446 20 however, the published literature offers little about the use of this software for studying usage of collections consisting of unique materials digitized and placed online by libraries and cultural heritage organizations. for example, betty has written about using google analytics to track statistics for user interaction with librarian-created digital media such as quizzes and video tutorials.4 fang discusses using google analytics to track the behavior of users who visited the rutgers-newark law library website.5 fang looked at the number of visitors, what and how many pages they visited, how long they stayed on each page, where they were coming from, and which search engine or website had referred them to the library’s website. findings were evaluated and used to make improvements to the library’s website. for example, fang mentions using google analytics data for tracking the percentage of new and returning visitors before and after the website redesign. among articles that discuss using web analytics to learn how users access digital collections, most have focused on a comparison between third-party platforms, online search engines, and the traditional library catalog to find preferred modes of access and whether results call for a shift in how libraries share their digital collections. for example, in their article on the impact of social media platforms such as historypin and pinterest on the discovery and access of digital collections, baggett and gibbs use google analytics for tracking usage of digital objects on the library’s website as well statistics collected from historypin’s and pinterest’s first-party analytics tools.6 the authors conclude that while neither historypin nor pinterest drive users back to the library’s website, they help in the discovery of digital collections and can enhance user access to library collections. schlosser and stamper compare the effects on usage of a collection housed in an institutional repository and reposted on flickr.7 whether housing a collection on a third-party site had an adverse effect on attracting traffic to the library’s website was not as important as ensuring users accessed the collection somewhere. likewise, o’english demonstrates how data from web analytics were used to compare access to archival materials via online search engines as opposed to library catalogs using marc records for descriptions.8 o’english argues library practices should change accordingly to promote patron access and use. ladd’s article on the access and use of a digital postcard collection from miami university uses statistics from google analytics, contentdm, and flickr over a period of one year.9 ladd’s findings reveal that few users came to the main digital collections website to search and browse; instead, most arrived via external sources such as search engines and social media sites. the resulting increase in views makes it imperative, ladd asserts, that regular updates both in contentdm and flickr are important for promoting access and use of the postcards. articles on using google analytics for tracking digital collection usage have explored tracking the geographic base of users. for example, herold uses google analytics to demonstrate usage of a digital archival collection by users at institutional, national, and international levels.10 herold looks at server transaction logs maintained in google analytics, onand off-campus searching counts, user locations, and repeat visitors to the archival images representing cultural heritage materials related to orang asli peoples and cultures of malaysia. she uses these data to ascertain information technology and libraries | december 2016 21 the number of users by geographic region and determine that, while most visitors came from the united states, malaysia ranked second. the data supported, according to herold, that this particular digital collection was able to reach another target audience: users from malaysia. herold’s findings indicate that digitization of unique materials makes them available to a worldwide audience. whether harvesting has increased usage of digital collections available via dpla or its hubs has received limited exploration in the literature. most writings on harvesting digital collections have focused more on the technical aspects of the process, like the dpla’s ingestion method, the quality and scalability of metadata remediation and enhancement,11 and large metadata encoding.12 for example, gregory and williams write about the north carolina digital heritage center as one of the service hubs of the dpla. the service hubs are centers that aggregate digital collection metadata provided by institutions for harvesting by the dpla. the authors discuss metadata requirements, software review, and establishment of workflow for sending large metadata feeds to the dpla.13 boyd, gilbert, and vinson, in their article on the south carolina digital library (scdl), another service hub for dpla, describe the planning behind setting up the scdl, its management, and the technology involved in metadata harvesting.14 freeland and moulaison discuss the missouri hub as a model for “institutions with similar collective goals for exposing and enriching their data through the dpla.”15 according to them, by harvesting their metadata to the dpla, institutions are able to share their digital collections with the broader public. additionally, institutions that harvest metadata to the dpla get value-added services like geocoding of locationbased metadata and expression of contributed metadata as linked data. data collection parameters hunter library digital collections usage data included information on item views16 and referrals17 for each of the collections including dpla referrals. the authors also considered keyword search terms18 across all referrals, and within contentdm specifically, that brought users to the library’s collections. the authors considered the most frequently occurring keywords to be representing the subjects of collections that were most used. repeat visitors to the library’s digital collections’ website were also tracked. finally, sessions19 were traced by the geographic area20 of the users. hunter library’s collections vary in size. the library’s largest and one of the oldest collections, craft revival [note: collections are set in roman and capitalized] showcases documents, photographs, and craft objects housed in hunter library and smaller regional institutions. the collection’s items represent the late nineteenth and early twentieth century (1890s–1940s) craft revival movement in western north carolina, which was characterized by a renewed interest in handmade objects, including cherokee arts and crafts. the craft revival collection began in 2005 and includes 1,982 items. the second largest collection, great smoky mountains, which highlights efforts that went into the establishment of the park and includes photographs on the landscape and flora and fauna in the park, began in 2012 and consists of 1,829 items. not all digital analyzing digital collections entrances: what gets used and why it matters | biswas and marchesoni | https://doi.org/10.6017/ital.v35i4.9446 22 collections were harvested to the dpla at the same time. while some older collections were harvested to the dpla in 2013, smaller, institution-specific collections started later were also harvested later. for example wcu—oral histories, a collection of interviews collected by students of one of wcu’s history classes documenting the history and culture of western north carolina and the lives of wcu athletes or artists’ like josephina niggli who taught drama at wcu; highlights from wcu, a collection of unique items from wcu’s mountain heritage center and other departments on campus, including letters from the library’s special collections transcribed by wcu’s english department students; and wcu—fine art museum, showcasing art work from the university’s fine art museum, were harvested to the dpla in 2015. as these smaller collections were started later, their total item views and referral counts would likely be less than some of the library’s older collections; however, these newer collections were included as they might provide valuable data regarding harvesting referrals and returning visitors. table 1 shows the years the collections were started, the number of items included

online exhibits—websites outside of contentdm that provide additional insight into the collection—since 2008 and began using google analytics to track its contentdm materials with the 6.1.2 release in october 2013. contentdm version 6.4 introduced a configuration field that allowed the authors to enter a google analytics id and automatically generate the tracking code in pages to simplify the setup. following that software update, oclc made google analytics the default data logging mechanism. the library set up google analytics such that online exhibits are tracked together with their contentdm collections. this is accomplished by using custom tracking on all webpages and a custom script in contentdm. this allows the library to link its contentdm and wcu.edu domains within google analytics so that sessions can be viewed across all online digital collections. data were collected from google analytics using several tools. google provides an online tool called query explorer (https://ga-dev-tools.appspot.com/query-explorer/) that can create and execute custom searches against google analytics. this application was used to craft the queries. microsoft excel was primarily used to download data, using the custom plugin rest to excel library (http://ramblings.mcpher.com/home/excelquirks/json/rest) to parse information from google analytics into worksheets. the excel add-on works well, but requires knowledge of microsoft visual basic for applications (vba) programming to use effectively. this limitation prompted the authors to look for a simpler way of retrieving data. the authors found openrefine (https://github.com/openrefine/openrefine) to collect, sort, and filter data, with excel used for results analysis. once in excel, formulas were used to mine data for specific targets. results analysis the data collected using google analytics spanned a period of approximately twenty-seven months, from october 2013 through december 2015. table 1 and graph 1 show each collection’s item views, item referrals, and size (number of items in the collection). these numbers were calculated for each collection as a percentage of total item views, total items referrals, and total number of items for all collections together. in table 2, the top five collections in terms of items views and referrals are highlighted. graph 1, a graphical representation of table 2, displays more starkly the differences between collections in terms of views and referrals. analyzing digital collections entrances: what gets used and why it matters | biswas and marchesoni |

collections by percentage information technology and libraries | december 2016 25 as demonstrated in the preceding table and graph, craft revival, one of the library’s oldest and largest collections, contributes more than 28 percent of all digital collections’ items and garners close to 42 percent of all item views and 53 percent of all item referrals. great smoky mountains, the second largest collection, contributes a little more than 26 percent of items but receives only about 8 percent of all item views and 7 percent of all referrals. the horace kephart collection, focusing on the life and works of horace kephart—author, librarian, and outdoorsman who made the mountains of western north carolina his home later in life—is the library’s fourth largest collection. it receives almost 12 percent of all item views and about 8 percent of all item referrals. picturing appalachia, the third largest collection—consisting of photographs showcasing the history, culture, and natural landscape of southern appalachia in the western north carolina region—makes up 14 percent of items and receives approximately 10 percent of all referrals and views. travel western north carolina—visual journeys of western north carolina communities through three generations—contributes fewer than 3 percent of items but scores high on both items views and referrals. wcu—making memories, which highlights the people, buildings, and events from wcu’s history, and stories of mountain folk (somf), which is a collection of radio programs from western north carolina non-profit catch the spirit of appalachia and archived at hunter library, are collections that are similar in size—receiving fewer than 3 percent of all item referrals. however, wcu—making memories receives a more than 7 percent of all item views compared to somf’s almost 4 percent. these findings are not surprising as the making memories collection documents western carolina university’s history and may receive many views from within the institution. overall, however, the craft revival collection can be considered the library’s most popular collection. the horace kephart collection appears to be the second most popular collection. and, not surprisingly, cherokee traditions, a collection of art objects, photographs, and recordings similar in content to the craft revival in terms of its focus on cherokee culture and history, is quite popular and receives more item referrals than both wcu—making memories and somf and more item views than somf (table 2). an analysis of keyword searches within contentdm and keyword searches across all referral sources reiterates these findings. as part of the analysis, data collected for this twenty-sevenmonth period for the top keyword searches within contentdm and the top keyword searches counting all referrals was recorded in an excel spreadsheet and then uploaded to openrefine. openrefine allows text and numeric data to be sorted by name (alphabetical) and count (highest to lowest occurring). once the excel spreadsheet was uploaded to openrefine, keywords were sorted numerically and clustered. openrefine has a “cluster” function to bring together text that has the same meaning but differs by spelling or capitalization (for example, “cherokee,” “cherokee,” “cheroke”) or by order (for example, “jane smith,” “smith, jane”). the clustering function provides a count of the number of times a keyword was used regardless of exact spelling. after identifying keywords belonging to a cluster (for example, a cluster of the word “cherokee” spelled differently), the differently spelled or organized keywords in each cluster were merged in analyzing digital collections entrances: what gets used and why it matters | biswas and marchesoni | https://doi.org/10.6017/ital.v35i4.9446 26 openrefine with their most accurate counterparts. finally, it should be noted that keywords including “!” and “+” symbols were most likely generated from either using multiple search terms within contentdm’s advanced search or from curated search links maintained on some of our online exhibit websites. these links take users to commonly used result sets within the collection. tables 3 and 4 provide a listing of the ten most frequently searched keywords within contentdm across all referrals and names of collections that are most relevant to these searches. keywords occurrence count relevant collection(s) cherokee 187 craft revival; cherokee traditions cherokee language 107 craft revival; cherokee traditions southern highland craft guild 98

“indian masks,” “indian wood carving,” “cherokee pottery”), artists (“amanda swimmer”), or topics relating to cherokee culture (“cherokee,” “cherokee language”). searches relating to the horace kephart collection (“horace kephart,” “kephart knife”) are also popular, explaining the fact that the kephart collection, which accounts for fewer than 8 percent of the library’s digital collections’ items scores highly in terms of item views (second) and referrals (fourth). the popularity of topics related to western north carolina is reiterated in the geographic base of the users. graph 2 shows north carolina accounts for most of the searches, with cities in western north carolina (asheville, franklin, cherokee, waynesville) accounting for more than 40 percent of sessions. analyzing digital collections entrances: what gets used and why it matters | biswas and marchesoni | https://doi.org/10.6017/ital.v35i4.9446 28 graph 2. cities by session count the majority of item referrals come from search engines such as google, bing, and yahoo! graph 3 shows the percentage of item referrals from these external searches.21 however, the dpla also generates a fair amount of incoming traffic to the collections. for example, while all collections get referrals from the dpla, harvesting to the dpla is particularly useful for smaller collections such as highlights from wcu, wcu—fine art museum, and civil war collection. each of these collections gets 17 percent of referrals from the dpla, making dpla the largest referral source following the search engines for the highlights and fine art museum collections. graph 4 shows referrals each collection receives via the dpla as a percentage of total referrals. this indicates the usefulness of harvesting to the dpla. a trend seems also to show there is an increase in total referrals from dpla per month the longer items are in dpla (graph 5). graph 3. percentage of search engine item referrals (google, bing, and yahoo!) 367 319 171 146 144 135 122

examine the usefulness of harvesting in promoting use. although usage data logs were unable to shed much light on the actual usefulness of the collections to users, the logs provided information on volume of use, what materials were accessed, and where users were located. analysis of the transaction logs indicates that while all collections likely benefitted from harvesting, craft revival, cherokee traditions, and horace kephart (collections focusing on the culture and history of western north carolina) were the most heavily used and most visitors came from the state of north carolina and from the region in particular. search terms in the transaction logs also indicated a strong interest in items related to cherokee culture and horace kephart. as herold, who traced the second largest group of users of the orang asli digital image archive to malaysia notes, the geographic base of a collection’s users can be indicative of the popularity of a subject area.22 likewise, matusiak asserts that users’ comments can be indicative of the relevance of collections to users’ needs and provide direction for the future development of digital collections.23 as neither the craft revival, cherokee traditions, nor horace kephart collection includes items that relate specifically to the university’s history—unlike other institution-specific collections mentioned earlier—it is possible collection users may be more representative of the larger public than the university. these findings point to the need for questioning identification of an academic information technology and libraries | december 2016 31 library’s user base as mainly students and faculty of the institution and whether librarians should give greater consideration to the needs of a wider audience.24 data supporting the existence of this user base, whose true import or preferences might not be captured in surveys and questionnaires, can serve as a valuable source of information for individuals responsible for building digital collections. in an informal survey of hunter library faculty carried out by hunter library’s digital initiatives unit in september of 2014, respondents considered collections such as craft revival to be more useful to users external to the university. while the survey could allude to the nature of the user base of a collection like craft revival, it understandably could not capture the scale of the item views and referrals garnered by this collection as well as a usage data analysis could. on the other hand, analysis of usage data, as demonstrated in this paper, indicated that certain collections— highlights from wcu, wcu—fine art museum, and wcu—oral histories—possibly served a niche audience. these smaller and more recently established collections consisting of universitycreated materials attracted more returning visitors (see graph 6). these returning visitors were likely internal users whose visits indicated, as fang points out, a loyalty to these collections.25 in the paper “a framework of guidance for building good digital collections,” authored by the national information standards organization framework advisory group, the authors point out that while there are no absolute rules for creating quality digital collections, a good collection should include data pertaining to usage.26 the authors point to multiple assessment matrixes including using a combination of observations, surveys, experiments, and transaction log analyses. as the wcu digital collections findings demonstrate, a careful analysis of the popularity of collections can indicate the need for balancing quantitative data with more qualitative survey and interview data. these findings also indicate that usage data analysis can be very valuable in identifying the extent of collection usage by visitors who may not have significant survey representation. results from the small (fewer than ten respondents) wcu survey indicate that some respondents question the institutional usefulness of collections such as craft revival. these results show the importance of taking multiple factors into account when assessing user needs and interests in digital collections. conclusion the authors feel future projects might stem from this data analysis. for example, local subject fields based on the highest recurring keywords that were mined from the transaction logs can be added for all of hunter library’s digital collections. usage statistics at a later period could be evaluated to study if addition of user generated keywords increased use of any collection. as matusiak points out in her article on the usefulness of user-centered indexing in digital image collections, social tagging—despite its lack of synonym control or misuse of the singular and plural—is a powerful form of indexing because of “close connection with users and their language,” as opposed to traditional indexing.27 the terms users assign to describe images are also the ones they are most likely to type while searching for digital images. likewise, according to walsh, a analyzing digital collections entrances: what gets used and why it matters | biswas and marchesoni | https://doi.org/10.6017/ital.v35i4.9446 32 study conducted by the university of alberta found more than forty percent of collections reviewed used a locally developed classification for indexing and searching their collections, and many of these schemes could work well for searches within the collection by users who are familiar with the culture of the collection.28 usage-data analysis can constitute useful information that guides decisions for building digital collections that better serve user needs. it can identify a library’s digital collections’ users and what they want. these are important considerations to keep in mind if library services are to be all about engaging and building relationship with the users.29 harvesting to a national portal such as the dpla is beneficial for hunter library’s collections. at the same time, the library’s institution-specific collections receive more return visits, likely because of sustained interest from the large user base of the university’s students and employees, an assessment supported by survey findings. conversely, collections not so directly tied to the institution receive the most onetime item views and referrals. items that get used are a good indication of what users want and, as this paper demonstrates, the focus of academic digital library collections should consider the needs of both the university audience and the general public. references 1. a landing page refers to the homepage of a collection. 2. the dpla provides a single portal for

catherine johnson information technology and libraries | june 2017 68 abstract during fall semester 2015, librarians at the united states naval academy were faced with the challenge of migrating to libguides version 2 and integrating libanswers with libchat into their service offerings. initially, the entire migration process was anticipated to take almost a full academic year; giving guide owners considerable time to update and prepare their guides. however, with the acquisition of the libanswers module, library staff shortened the migration timeline considerably to ensure both products went live on the version 2 platform at the same time. the expedited implementation timeline forced the ad hoc implementation teams to prioritize completion of the tasks that were necessary for the system to remain functional after the upgrade. this paper provides an overview of the process the staff at the nimitz library followed for a successful implementation on a short timeline and highlights transferable lessons learned during the process. consistent communication of expectations with stakeholders and prioritization of tasks were essential to the successful completion of the project. introduction academic libraries all over the united states have migrated from libguides version 1 to the new, sleeker, responsive design of version 2. approaches to the migration can differ vastly depending on library size, staff capabilities and time frame available for completing the project. in 2015, the nimitz library at the united states naval academy, began planning to both upgrade libguides to version 2 and to acquire libanswers with libchat. the web team and reference department partnered to migrate the libguides platform and integrate libanswers into the library’s web presence. the library first adopted springshare’s libguides in 2009. by 2015, the subscription had grown to 61 published guides with 10,601 views. the libguides collection was modified and expanded during two web site upgrades and several staffing changes. throughout 2014 and 2015, library staff periodically discussed the possibility of upgrading to the version 2 interface, but timing, brianna buljung (bbuljung@mines.edu) is instruction & research librarian, colorado school of mines, golden, co. catherine johnson (cjohnson@usna.edu) is head of reference & instruction at the united states naval academy, annapolis, md. up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 69 staffing vacancies and the priority of other projects kept the migration from taking place. in late summer 2015, with the acquisition of springshare’s libanswers with libchat pending, staff determined that it was finally time to migrate to the new libguides interface. initially, the migration team planned to spend nearly a full academic year completing the migration process. this timeline would provide guide owners with ample time for staff training, revising guides, conducting usability testing and preparing the migrated guides to go live without distracting from their other duties. however, right before starting the project, the library finalized the acquisition of springshare’s libanswers with libchat which they decided to launch with the version 2 interface. the team pushed up the libguides migration by several months to keep from confusing patrons with multiple interfaces and launch dates. the migration of libguides and the implementation of libanswers would take place during the fall semester and both products would go live in the version 2 interface before the start of the spring semester. this paper provides an overview of the process that the staff at nimitz library followed for a successful implementation on a short timeline and highlights transferable lessons learned during the process. the authors also include a post-implementation reflection on the process. literature review much of the currently available literature on migration of platforms, especially the libguides platform is published informally. librarians from universities across the country have created help guides, checklists and best practices for surviving the migration. most migration help-guides are tailored to each specific institution but they can still provide helpful suggestions that can be adapted by another.1 springshare also provides extensive help content and checklists, including a list of the most important steps for administrators to complete.2 however, little of the available literature discusses the minimally acceptable amount of work needed to be completed by guide authors. this type of information was crucial to the nimitz library team after drastically shortening the migration timeline. a clearly delineated list of required and optional tasks was needed for guide owners, given time constraints and other job duties. in addition to the informally published help materials, several articles have been published on various aspects of research guide design and evaluation. a few articles examine the migration process. hernandez and mckeen offer advice for libraries contemplating migration; including setting goals and performing usability testing against the new guides.3 duncan et al provide a case study of the implementation process at the university of saskatchewan.4 some articles discuss the basics of guide design and usage in the library. these best practices can be adapted to different platforms, web sites and user populations. they discuss the importance of various web design elements such as word choice and page layout.5 another aspect the literature exposes is student use of the guides.6 finally, usability of research guides is one of the most important and widely discussed topics in the literature. creating and maintaining guide content depends on the user’s ability to locate and use the guides in their research.7 most often, research guides are designed up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 70 with the student in mind; to assist them in beginning a project, researching when a librarian is unavailable or as a reference for follow-up after an instruction session.8 as pittsley and memmott discuss, navigation elements can impact a student’s use of research guides.9 the process as preparations for the migration began, it became immediately apparent that the web team and reference department would have to divide the project into manageable segments to complete the work without overwhelming guide owners. three ad hoc teams, made up of librarians from several different departments, were created to take the lead on different elements of the project. the migration team was responsible for researching, organizing and supervising the migration of libguides to version 2. the libanswers team learned about libanswers and how to effectively integrate the product into the library’s web site. the libchat team tested the functionality of libchat and determined how it would fit into the library’s reference desk staffing model. dividing the project into manageable segments allowed each team to focus on the execution of their area of responsibility. the team approach allowed the library to draw on individual strengths and staff willingness to participate without depending on one single staff member to manage the entire migration and implementation process on such a short timeline. migration team the migration team was responsible for determining the tasks that were mandatory for guide owners to complete, the amount of training they would need to use the new interface and how each product should be incorporated into the library’s web site. the libguides migration team relied heavily on advice from other libraries and the documentation from springshare to guide them in determining mandatory tasks. the engineering and computer science librarian reached out to the asee engineering libraries division listserv for advice from peer libraries that had already completed migration. the team also made use of the springshare help guides and best practices guides posted by other universities. ultimately, the migration team created checklists and spreadsheets to help guide owners prepare their guides for migration. a pre-migration checklist (appendix a) was shared with guide owners; containing all of the required and optional tasks that needed to be completed before the migration took place in early november. tasks such as deleting outdated or unused images and evaluating low use guides for possible deletion were required for guide owners to complete. other tasks such as checking each guide for a friendly url or checking database descriptions for brevity and jargon free language were encouraged but considered optional. the team determined that items directly related to the ability of post-migration guides to function properly made the required list, while more cosmetic or stylistic tasks could be completed on a time-allowed basis. a post-migration checklist (appendix b) was created for guide owners following the migration. this list included portions of the guides that had to be checked to ensure widgets, links and other assets had up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 71 migrated properly. both checklists were accompanied by tips, screenshots, deadlines and indicated which team member to contact with questions. clear explanation of the expectations for the project, and accommodating the guide owners’ busy schedules made the migration more successful. the migration team gave the new, more robust a-z list significant attention. libguides version 2 allows the a-z list to be sorted by subject, type and vendor. it also allows a library to tag “best bets” databases in each subject area. the databases categorized as best bets display more prominently in the list of databases by subject. using google sheets, the electronic resources librarian quickly and easily solicited feedback from liaison librarians about which databases to tag as best bets for each subject area. google sheets also made it easy for librarians to edit the list of databases related to their subject expertise. some databases had been incorrectly categorized and, in some subjects, newer subscriptions didn’t appear on the list. libguides version 2 allows users to sort databases by type, but doesn’t provide a predetermined list of types. in order to create the list of material types into which all databases would be sorted, the migration team examined lists found on other library web sites. several lists were combined and duplicates, or irrelevant types were removed. an additional military specific type was added to address the most common research conducted by midshipmen. then, the liaison librarians were solicited for input on the language used to describe each type and which databases should be tagged by each type. name choices are a matter of local preference, such as having a single type category for both dictionaries and encyclopedias, or two separate categories. to keep the list of material types to a manageable length, the team decided that each type must contain more than one or two databases. it takes time to get well defined lists of subjects and types. staff working with patrons are able to gather informal feedback about the categorizations in their current form, and make suggestions, corrections, or additions based on patron feedback. the migration of libguides and acquisition of libanswers provided the reference department and web team with an opportunity to update policies and establish new best practices for guide owners. one important cosmetic update included more encouragement for guide owners to use a photo in their profiles. profile pictures had been used inconsistently in the first libguides interface, and several guide owners used the default grey avatar. guide owners who were reluctant to have a headshot on their profile were encouraged to take advantage of stock photos made available through the naval academy’s public affairs office. a photo shoot was also organized for guide owners. on a voluntary basis, guide owners spent about an hour helping each other to take pictures in and around the library. the event helped to get a collection of more professional photos for guide owners to choose from. another important update was the re-evaluation of libguides policies in light of the new functionality available in version 2. the guide owners gathered for a meeting midway through the pre-migration guide cleanup process to troubleshoot problems and consider best practices for the up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 72 new interface. guide owners discussed the standardization of tab names in the guides, the information important to include in author profile boxes, and potential categories for the “types” dropdown in the a-z database list. the meeting provided a great opportunity to discuss the options available to guide owners and to solicit feedback on interface mock-ups and guide templates created by the systems librarian. many items from the discussion were incorporated into the update libguides policies for guide owners. libanswers and libchat teams integrating libanswers with libchat, an additional springshare product, at the same time as the migration to libguides version 2 is not necessary. because the acquisition of libanswers coincided with the need to upgrade to version 2, the library staff determined that the two should be done at the same time in order to minimize disruption for patrons. the ad hoc teams tasked with implementing libanswers and libchat met regularly to learn about the new products and to consider how these products would fit into the library’s existing points of service. while the libanswers and libchat teams began as two distinct groups, it became increasingly clear that the functionality of these two systems is interwoven so closely that they must be reviewed and discussed together. the teams spent considerable time learning the functionality of the new systems, considering how the new service points would integrate into the existing offerings, and creating draft policies to provide guidance to staff. the teams developed a set of tips and guidelines to address staff concerns and provide guidance on how the new system should be used (see appendix c). the teams also held training sessions focused on providing opportunities for staff to explore and practice using the new products. although the implementation of libanswers with libchat was not necessary to upgrade to libguides version 2, undertaking all of these upgrades at once allowed the ad hoc groups to collaborate with ease, define policies and procedures that would help these products integrate seamlessly with existing services, and prevent change fatigue within the library. updating the library website the final element of migration and implementation the teams had to consider was integration into the library’s existing web site. many elements of the library’s site are dictated by the broader university web policy and content management system. however, working within guidelines the teams were able to take advantage of the new libguides interface, especially the more robust a-z list of databases, to provide users with multiple ways of accessing the new tools. the library makes use of a tabbed box to provide entry to summon, the catalog, the list of databases and libguides. the new functionality of libguides version 2 enabled the team to provide easier access directly to the alphabetical listing of databases. the libguides tab was also updated to provide a drop down list of all the guides and a link to browse by guide owner, subject or type of guide. these enhancements saved time for the user and cut down on the number of clicks needed to access database content licensed by the library. up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 73 integrating the libanswers product into the site was achieved by providing several different ways for patrons to access it. an faq tab was added to the main tabbed box to provide quick access to libanswers, complete with a link to submit questions. the “contact us” section on the site home page was updated to include a link to libanswers as well as newer, more modern icons for the different contact methods. all guide owners were instructed to update the contact information on their guides to include a libanswers widget. a great source of inspiration on integrating the tools into the library site came from looking at other library web sites. the teams worked from the list of libguides community members provided on the springshare help site and by viewing the sites of known peer libraries. working through an unfamiliar web site can be a quick way to find design ideas and work flows that are successful and attractive. team members found wording, icons and placement ideas that could be adapted for use on the nimitz library site. advice for managing a short migration timeline while on a short implementation timeline or with a small staff that has to accomplish this project in addition to their regular duties, it's important to consider a few strategies that can make the process simpler and less stressful. first, communicate expectations with everyone involved in the project at all steps of the process. determine which stakeholders need to know about the various checklists and upcoming deadlines. communicating needs and expectations throughout the entirety of the project reduces confusion and enables teams and individual guide owners to complete the project on time. although libguides had predominantly been the domain of the nimitz reference department, projects of this scale also impacted other parts of the library, from systems to the electronic resources librarian. email communication and short notices in the library’s weekly staff update were the primary means of communication with stakeholders. documents were shared via google drive to provide guide owners with a centralized file of help materials. also, the point of contact for questions with each element of the migration was clearly identified on each checklist and tip sheet. this single addition to the checklists helped guide owners to quickly and easily get questions and technical issues addressed. on a short timeline it is also important to consider the elements that are crucial for completion and those that can be delayed. some critical needs in a libguides migration include deleting guides that are no longer being used, checking for boxes that will not migrate and deleting bad links. these tasks must be completed by guide owners or administrators to ensure that the migrated data formats properly. careful attention to these tasks also save the staff unnecessary work on updating and fixing the new guides before going live. other elements of guide design and migration are merely nice to have. they complement the user’s experience with the final product but neglecting them will not affect basic functionality. these secondary tasks can be completed as time allows. for guide owners, optional tasks include shortening link descriptions, checking for a up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 74 guide description and friendly url and other general updates to the guides. the migration was broken into manageable tasks by giving guide owners a clear list of required and optional items. team leaders will also need to manage expectations. it can be difficult to remember that web pages, especially libguides, are living documents. they can be updated fairly easily after the system has gone live. on a short timeline, in the midst of other duties and responsibilities, it is acceptable for a guide to be just good enough. there is rarely enough time for each guide to reach a state of perfection prior to going live. a guide that is spell-checked and contains accurate information can be edited and made more aesthetically pleasing as time allows after the entire site has gone live. while additional edits are taking place, students still have access to the information they need for their academic work. lists, such as the subjects and material types in the a-z list, are always a work in progress based on feedback from service points and usability testing. updates and edits should be made as patrons interact with the products. regular use can help library staff identify problems with or confusion about the products that might not be anticipated prior to going live. stress on guide owners can be greatly reduced by communicating expectations throughout the process. post-implementation nimitz library successfully went live with both libguides version 2 and libanswers with libchat in early january 2016, right before midshipmen returned to campus for the spring semester. libanswers with libchat was introduced to the campus community with a soft launch at the beginning of the spring semester due to staffing levels and shifts at the reference desk. the librarian on duty at the reference desk was also responsible for answering any chats or libanswers questions initiated during their shift. the volume of questions remained fairly low during the semester. on average, the library received two synchronous and 1.5 asynchronous incoming questions per week via libanswers with libchat. the low volume was beneficial in that it allowed librarians to become familiar with answering questions and editing faqs. they were able to handle both face-to-face interactions with patrons in the library and the web traffic. however, the volume was so low that it became apparent more marketing of the service was needed. at the start of the fall 2016 semester, the library made an effort to increase awareness of the new libanswers products by emailing all students, mentioning the service in every instruction session, and creating fliers advertising the service and distributing them around the library. though data is preliminary, statistics have shown that use of these services has more than tripled in the first month of the new semester. as discussed above, the expedited implementation timeline forced the ad hoc teams to prioritize completion of the tasks that were necessary for the system to remain functional after the upgrade. this meant other necessary, but not urgent, updates to guides were left untouched during the migration. given the amount of effort needed to prepare the guides for migration, it is understandable that guide owners had grown tired of making libguides updates and found it up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 75 necessary to move on to other projects. with this fatigue in mind, the team leaders will continue to remind guide authors that libguides are living pages in need of constant attention. the team leaders will also take advantage of user feedback to promote continued updates to libguides. throughout the migration process team leaders solicited feedback from staff and users in a variety of ways. first, reference staff wereinformed of design and implementation changes made throughout the migration. they were given time to view and evaluate the master guide template prior to the migration. the team solicited feedback on the names and organization of categories in the a-z list. after the products went live, the team gathered informal feedback through reference desk interviews, in information literacy instruction sessions and in conversations with faculty and students. student volunteers participated in usability testing during the spring semester. they were asked to complete a series of tasks related to the different aspects of the new interface. their feedback, especially from thinking aloud while completing the tasks, revealed to librarians how students actually use the guides. both formal and informal feedback helped librarians adapt and improve the guides. based on the feedback, the systems librarian made global changes to improve system functionality. in one instance, users were having difficulty submitting a new libanswers question when they could not find an appropriate faq response. the systems librarian made the “submit your question” link more prominent for users in that situation. the libguides continue to be evaluated by staff for currency and ease of use. in discussing the first round of usability test results it was determined that more testing during the fall semester of 2016 would be helpful. during the upgrade to version 2 and implementation of libanswers with libchat, librarians focused on the functions in the system that were most essential or most desired. all of these products contain additional functionality that was not implemented during the upgrade. after a brief rest, the reference department and library web team explored the products’ additional functionality and determined what avenues to explore next. conclusions migration of any platform can be an extensive and time consuming task for library staff. preparations and post-migration clean up can interrupt staff workflows and strain limited resources. using migration teams was a successful strategy on a short timeline because it helped spread the workload by delegating specific learning and tasks to specific people. those people, in turn, became experts in their area of focus and served as a resource for others in the library. this model cultivated a sense of ownership in the migration across many stakeholders that might not have otherwise existed. that sense of ownership in the project, coupled with checklists and spreadsheets full of discrete tasks in need of completion made it possible for a small staff to complete the migration quickly and successfully. migrating on a short timeline can be especially stressful but careful planning and good communication of expectations helps stakeholders focus on the end goal. upon completion of the project there was a very real sense of fatigue with this up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 76 project. as a result, tasks that were listed as optional because they weren’t critical for migration went unattended for quite some time after the migration. slowly, months later, guide owners are ready to revisit guides and continue making improvements. if given more time, this migration may have been completed more methodically and with the intent of having everything perfect before moving on to the next step. instead, working on a tight timeline forced us to continue moving forward, making necessary changes, and making note of changes to be made in the future. ultimately, it was a constant reminder that our online presence is and should be a constant work in progress, not the subject of a big, occasional update. references 1. luke

update to your version 1 guides, your change will not transfer to version 2. this means broken links will need to be fixed in both versions. if there are issues or questions contact the head of reference & instruction (general questions), the systems librarian (technical issues), or the electronic resources librarian (database assets and a-z list). clean up and check content 1) check boxes to make sure content is correctly displayed on all your guides. check all boxes closely, as some had the header end up below the first bullet point. for example: to fix an issue like this click on at the bottom of the box you are working on. then click on “reorder content”. you can move the links down and the text up 2) ensure all guides have a friendly url, are assigned to a subject, have assigned tags if you didn’t do this pre-migration. see the premigration handout for help. in version 2 this information will display at the top of our guides in edit mode and at the bottom of our guides on the public interface. 3) ensure images are resized to fit general web guidelines see this guide for help http://guidefaq.com/a.php?qid=12922 4) check all your widgets to ensure they still function properly 5) add a guide type to each of your guides. this is a new feature in libguides version 2. it is under the gear on the right side of your guide while in edit mode. this will help us sort and organize them in the list of guides. up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 82 add new libguides 2 content 1) make a box pointing to related guides. research has shown that a box on the guide home page pointing to related guides can be very helpful to students. link to other subject guides that would be of interest and any course guides for that subject. for example: the box on the mechanical engineering guide contains links to em215 and nuclear engineering (which is part of the mechanical engineering department). to do this go to the bottom of your welcome box, click the add/reorder button, and then on guide list, your first option is to manually choose guides to add to the list. 2) add a tab to every guide that is named citing your sources and redirects to the citing your sources libguide. to do this: a. create a blank page named citing your sources at the bottom of your left side navigation b. on your blank page click on the to open the options for editing the page. c. click on redirect url and paste the link to the citing sources guide in the box. d. it is also a good idea to mark the open in a new window box as well e. if you’ve completed it successfully your citing your sources tab will look like this in edit mode. since the citing your sources guide is still a work in progress it is unpublished and you will get an error when you preview it. up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 83 f. finally, remove the plagiarism and citing sources box from your guides. 3) now is a good time to take advantage of new functionality and to update the content of your guides. you can now combine multiple types of information into the same box, you can also take advantage of tabbed boxes. see this libguide for further assistance:

https://doi.org/10.6017/ital.v36i2.9585 84 appendix c: tips & guidelines for libanswers with libchat what modes of inquiry will be available to users? using the libanswers platform, users will be able to submit questions via chat or by using the question form within libanswers. users will also be able to ask questions as they did before: at the reference desk, via askref@usna.edu, and by calling 410-293-2420. what are “best practices” or guidelines for libanswers w/ libchat? see the tips for responding to tickets at the bottom of this document. see the tips for creating/maintaining faq at the bottom of this document. see the tips for responding to chat questions at the bottom of this document. what priority should i give responses coming through various modes of inquiry? reference staff will have to use their professional judgement when deciding what priority to give questions coming in through various modes of inquiry. while the addition of chat and tickets may seem overwhelming at first, the same rules you’ve applied in the past will work. if a chat comes in while you’re helping someone face-to-face, use that as an opportunity to advertise the chat service. explain to the patron that you also help users via chat and you’re going to let the chatter know that you’ll be with them shortly. the same can apply if you’re finishing up a chat when a face-to-face user walks up. simply explain that the library also offers a chat service and you’re just finishing up a question. remember to get comfortable with and take advantage of the canned messages in chat, let the phone go to voicemail if necessary, and explain to face-to-face users what’s happening. during the pilot phase you should also keep track of strategies that worked well for you, or times when the various modes of inquiry became too overwhelming. we’ll take all of that into consideration when we reexamine this service. chat, phone, and face-to-face interactions are synchronous modes of communication, so users expect responses immediately. tickets are asynchronous modes of communication and should be dealt with on a first come, first served basis. respond to tickets when you have time. when responding to tickets, respond to the oldest tickets first as that user has been waiting the longest for an answer. however, feel free to use your judgement and, if you choose, respond to questions with quick answers right away. how should i prioritize questions from usna v. non-usna users? priority should be given to midshipmen, faculty, and staff. if an outside user makes use of the chat or ticket service, feel free to explain to them that this service is primarily for faculty/staff/students and they should direct their question to askref@usna.edu. if you are free and have time, feel free to assist outside patrons via the chat or ticket system. up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 85 how should i handle remaining questions during a change in shifts? handle them in the same manner that you would a face-to-face question with a student, faculty, or staff member. finish up quickly if you can, advise the patron that you need to leave and offer to handle the question when you return, or transfer the chat to another librarian. if there are remaining tickets in the queue, simply notify the next librarian on duty. what are the expected turnaround times for responding to patron inquiries? chat, face-to-face, and phone inquiries should be responded to as immediately as possible. tickets should be responded to within a business day. who can i contact for help and troubleshooting? if you have questions, your first stop should be the libanswers faq, provided by springshare (available in the “help” section when logged into libapps). if you can’t find the answer to your question there, feel free to contact the head of reference and instruction, who will work to resolve the problem with you. guidelines for responding to libanswers tickets*: ● keep in mind that when you are responding to tickets, you are a jack of all trades. that means even if the question is outside of your subject area, you should do your best to provide the user information that will get them started. in that email you may also suggest that the user contact the subject specialist. ● respond to libanswers tickets in the same way you would respond to an email inquiry from a user. ● if you provide a factual response, be sure to include the source from which that information came. guidelines for creating/maintaining faqs*: ● the faq database is a public-facing, searchable collection of questions and answers. the intent is to empower our users to find their answers. any question that might be considered a frequently asked question should be included in the faq. this might include questions about the library, the collections, how to find specific types of information, how to start research on specific and recurring assignments etc. ● when creating an faq from a ticket, remember that you can edit the question. do your best to format the question in a way that would be applicable and relevant to the most users. ● when creating an faq from a response you’ve already written, be sure to edit out any personally identifiable information (pii) about the person who initially asked the question. be sure to check the question and response for any pii. up against the clock: migrating to libguides v2 on a tight timeline | buljung and johnson https://doi.org/10.6017/ital.v36i2.9585 86 ● if you want to modify an faq: if a member of the staff notices incomplete or incorrect information in an faq response, he/she should use professional judgement in deciding how to handle the situation. if it’s an error that may have been caused by a typo, he/she may choose to edit the response immediately. however, if the edit impacts the substantive content of the response, he/she may choose to consult with the librarian who initially wrote the response. guidelines for libchat*: ● if you refer a question, alert the librarian to whom the user is being referred. ● remember the person you’re chatting with can’t see you so if you leave (to conduct a search, to check a book, to help someone else etc.) let them know you’ll be right back. ● sometimes chat questions can seem rushed, so it may be tempting to answer the initial question. remember, like face-to-face interactions, clarifying queries save time for the user and the librarian, allowing for the provision of more accurate and efficient answers. ● when providing responses, remember that as an academic library, our mission is to provide the information needed and to instruct our users so they may become self-reliant; chat challenges us to balance providing answers and instruction. do your best to find an appropriate balance. ● as the transaction is ending, remain courteous, check that all the user’s questions have been addressed, and encourage them to use the service again. * note: these guidelines are drafts and will evolve as the staff learns more about this system throughout the pilot phase. topic modeling as a

(mark.fienup@uni.edu) is an associate professor in the computer science department, university of northern iowa. © 2021. abstract library chat services are an increasingly important communication channel to connect patrons to library resources and services. analysis of chat transcripts could provide librarians with insights into improving services. unfortunately, chat transcripts consist of unstructured text data, making it impractical for librarians to go beyond simple quantitative analysis (e.g., chat duration, message count, word frequencies) with existing tools. as a stepping-stone toward a more sophisticated chat transcript analysis tool, this study investigated the application of different types of topic modeling techniques to analyze one academic library’s chat reference data collected from april 10, 2015, to may 31, 2019, with the goal of extracting the most accurate and easily interpretable topics. in this study, topic accuracy and interpretability—the quality of topic outcomes—were quantitatively measured with topic coherence metrics. additionally, qualitative accuracy and interpretability were measured by the librarian author of this paper depending on the subjective judgment on whether topics are aligned with frequently asked questions or easily inferable themes in academic library contexts. this study found that from a human’s qualitative evaluation, probabilistic latent semantic analysis (plsa) produced more accurate and interpretable topics, which is not necessarily aligned with the findings of the quantitative evaluation with all three types of topic coherence metrics. interestingly, the commonly used technique latent dirichlet allocation (lda) did not necessarily perform better than plsa. also, semi-supervised techniques with human-curated anchor words of correlation explanation (corex) or guided lda (guidedlda) did not necessarily perform better than an unsupervised technique of dirichlet multinomial mixture (dmm). last, the study found that using the entire transcript, including both sides of the interaction between the library patron and the librarian, performed better than using only the initial question asked by the library patron across different techniques in increasing the quality of topic outcomes. introduction with the rise of online education, library chat services are an increasingly important tool for student learning.1 library chat services have the potential to support student learning, especially for distant learners who have a lack of opportunity to come and learn about library and research skills in person. in addition, unlike traditional in-person reference services whose use has declined drastically, library chat services have become an important communication channel that connects patrons to library resources, services, and spaces.2 quantitative and qualitative analysis of chat transactions could provide librarians with insights into improving the quality of these resources, services, and spaces. for example, in order to maximize patrons’ satisfaction, librarians could identify or evaluate quantitative and qualitative mailto:hyunseung.koh@uni.edu mailto:mark.fienup@uni.edu information technology and libraries september 2021 topic modeling as a tool for analyzing library chat transcripts | koh and fienup 2 patterns of chat reference data (e.g., busiest days and times of nondirectional, research-focused questions) and develop a better staffing plan for assigning librarians or student employees to most appropriate days and times. furthermore, these insights could be used to help demonstrate library value by showing external stakeholders how successfully library chat services support students’ needs, which is increasingly in demand for higher education. 3 in practice, it is burdensome for librarians to go beyond simple quantitative analysis (e.g., chat duration, message count, word frequencies) with existing chat software tools, such as libraryh3lp, questpoint, springshare’s libchat, and liveperson.4 currently, in order to obtain rich and hidden insights from large volumes of chat transcripts, librarians need to conduct manual qualitative analysis of chat transcripts with unstructured text data, which requires a lot of time and effort. in an age when library patrons' information needs have been changing, the lack of chat analysis tools that handle large volumes of transcripts hinders librarians’ ability to respond to patrons’ wants and needs in a timely manner.5 in particular, small and medium-sized academic libraries have seen a shortage of librarians and need to hire and train student employees , so librarians’ capabilities for real-time quick and easy analysis and assessment will become critical in helping them take appropriate actions to best meet user needs.6 as part of an effort to develop a quick and easy analysis tool for large volumes of chat transcripts, this study applied topic modeling, which is a statistical technique “for learning the latent structure in document collections” or “a type of statistical model for finding hidden topical patterns of words.”7 we compared outcomes of different types of topic modeling techniques and attempted to propose topic modeling techniques that would be most appropriate in the context of chat reference transcript data. literature review to identify the most appropriate research methods that would facilitate analyzing a vast amount of chat transcripts, this section first introduces literature in relation to research methods used in analyzing chat transcript data in library settings and nonlibrary settings. it follows by discussing different types of topic modeling techniques that have high potential for quick and easy analysis of chat transcripts and their strengths and weaknesses. chat transcript analysis methods in library settings in analyzing library chat transcripts, which are one major data source of library chat service research, researchers have used variants of quantitative and qualitative research methods.8 coding-based content analysis with or without predefined categories is one type of qualitative method.9 the other type of qualitative research method is conversation or language usage analysis but it is not a dominant type of research method, as compared to coding-based qualitative content analysis.10 the most common quantitative methods are simple descriptive countor frequencybased analyses that are accompanied by qualitative coding-based content analyses.11 in some recent research, advanced quantitative research methods, such as cluster analysis and topic modeling techniques, have been used, but they have not been fully explored yet with a wide range of techniques.12 chat transcript analysis methods in nonlibrary settings as shown in table 1, researchers in nonlibrary settings also used research methods in analyzing chat data from diverse technology platforms or contexts, ranging from qualitative manual coding methods to data mining and machine learning techniques. topic modeling techniques are one of the chat analysis methods, but again, it seems that they have not been fully explored yet in chat analyses in nonlibrary settings, even though they have been used in a wide range of contexts.13 information technology and libraries september 2021 topic modeling as a tool for

topic modeling techniques and their strengths and weaknesses as a quantitative and statistical method appropriate for analyzing a vast amount of chat transcript data, researchers from both library and nonlibrary settings used topic modeling. as shown in table 2, conventional topic modeling techniques include latent semantic analysis, probabilistic latent semantic analysis, and latent dirichlet allocation, each of which has its unique strengths and weaknesses.18 in order to overcome weaknesses of the conventional techniques, researchers have developed alternative techniques. for example, dirichlet multinomial mixture (dmm) has been proposed to overcome data sparsity problems in short texts.19 as another example, correlation explanation (corex) has been proposed to avoid time and effort to identify topics and their structure ahead of time.20 last, guided lda (guidedlda) has been proposed to improve performance of infrequently occurring topics.21 information technology and

analysis, and evaluation this section first introduces the data used for this study. next, it explains the procedures of each stage starting from preprocessing to analyzing chat transcript data using different types of conventional and alternative topic modeling techniques. last, it discusses quantitative and qualitative evaluation in terms of the quality of topic outcomes across different types of topic technique. for more details including python scripts please visit our github page at https://github.com/mfienup/uni-library-chat-study. https://github.com/mfienup/uni-library-chat-study information technology and libraries september 2021 topic modeling as a tool for analyzing library chat transcripts | koh and fienup 5 data this study collected the university of northern iowa’s rod library chat reference data dated from april 10, 2015, to may 31, 2019 (irb#18-0225). this raw chat data was downloaded from libchat in the form of an excel spreadsheet with 9,942 english chat transcripts with each transcript as a separate row. preprocessing as the first step, this study removed unnecessary components of each chat transcript using a custom python script. components removed were timestamps, patron and librarian identifiers, http tags (e.g., urls), and non-ascii characters. next, it processed the resulting text words using python’s natural language toolkit (https://www.nltk.org/) and its wordnetlemmatizer function (https://www.nltk.org/_modules/nltk/stem/wordnet.html) to normalize words for further analyses. as the final step, it prepared the four types of data sets to identify which type of data set would produce better topic outcomes. the four types of data sets were as follows: • question-only: consists of only the initial question asked by the library patron in each chat transcript. only the latter 10.7% of the chats recorded in the excel spreadsheet contained an initial question column entry. the remaining chats assumed to contain their initial question in the patron’s first response if it was longer than a trivial welcome message. • whole-chat: consists of the whole chat transcripts from the library patron and librarians. • whole-chat with nouns and adjectives: consists of only nouns and adjectives as parts of speech (pos) from the whole chat transcripts. • whole-chat with nouns, adjectives, and verbs: consists of only nouns, adjectives, and verbs as pos from the whole chat transcripts. the first two data sets were prepared to examine if the first question initiated by each patron or the whole chat transcripts would help produce better topic outcomes. the last two data sets were prepared to examine which parts of speech retained would help produce better topic outcomes. data analysis with conventional topic modeling techniques this study first analyzed chat reference data using three conventional topic modeling techniques: latent semantic analysis (lsa), probabilistic latent semantic analysis (plsa), and two versions of latent dirichlet allocation (lda), as shown in table 3. all three techniques are examples of unsupervised topic modeling techniques that automatically analyze text data from a set of documents (in this study, a set of chat transcripts) to infer predominant topics or themes across all documents without human help. a key challenge, or a key parameter to be determined, for unsupervised topic modeling techniques is to identify the optimal number of topics. the study ran the commonly used lda technique with the whole-chat data set with various numbers of topics. fifteen was chosen as an optimal number of topics for this study by calculating and comparing the log-likelihood scores among various number of topics. https://www.nltk.org/

dated february 26, 2019 also, before analyzing chat transcript data using lsa and plsa, this study performed a term frequency–inverse document frequency (tf–idf) transformation. tf–idf is a measure of how important a word is to a document (i.e., a single chat transcript) compared to its relevance in a collection of all documents. data analysis with alternative topic modeling techniques in addition to conventional topic modeling techniques, this study analyzed chat reference data using three alternative techniques of dirichlet multinomial mixture (dmm), anchored correlation explanation (corex) and guided lda (guidedlda), as shown in table 4. this study selected dmm as an alternative unsupervised topic modeling technique that has been developed for short texts. also, this study selected anchored corex and guided lda (guidedlda) as semi-supervised topic modeling techniques that require human-curated sets of words, called anchors or seeds, which nudge topic models toward including the suggested anchors. this is based on the assumption that human’s curated techniques would help produce better quality of topics than the unsupervised techniques. for example, the three words “interlibrary,” “loan,” and “request,” or the two words “article” and “database,” are possible anchor words in the context of library chat transcripts. such anchor words can appear anywhere within a chat in any order. https://pypi.org/project/gensim/ https://scikit-learn.org/stable/modules/generated/sklearn.decomposition.nmf.html

10/5/2017 given that a known set of anchor words associated with academic library chats seems unavailable in the literature, this study decided to obtain a list of most meaningful anchor words by combining outcomes of the unsupervised techniques with a human’s follow-up curation, as follows: step 1. execute unsupervised topic modeling techniques step 2. combine resulting topics from all unsupervised topic modeling techniques step 3. identify a list of all possible pairs of words (bi-occurrences), e.g., 28 pairs of words if each topic has 8 words, and all possible combinations of tri-occurrences of words step 4. identify most common bi-occurrences and tri-occurrences of words across all topics by ordering in descending order by frequency step 5. select a set of anchors from these bi-occurrences and tri-occurrences of words by a human’s judgment in terms of selecting a set of anchor words, the librarian author of this paper judged whether combinations of words in each row from step 4 were aligned with frequently asked questions or easily inferable themes in academic library contexts. as shown in table 5, a set of “interlibrary,” “loan,” and “request” was selected as anchor words that are aligned with one frequently asked question about interlibrary loan requests, whereas a set of “access,” “librarian,” and “research” was not selected as anchor words because multiple themes, such as access to resources and asking for research help from librarians, can be inferred. additionally, a set of “hour,” “time,” and “today” was selected over a set of “time,” “tomorrow,” and “tonight” as better or clearer anchor words. https://github.com/qiang2100/sttm https://github.com/qiang2100/sttm https://github.com/gregversteeg/corex_topic

with topic coherence metrics comparing the quality of topic outcomes across various topic modeling techniques is tricky. purely statistical and quantitative evaluation techniques, such as held-out log-likelihood measures, have proven to be unaligned with human intuition or judgment with respect to topic interpretability and coherency.23 thus, this study adopted the three topic coherence metrics of tcpmi (normalized pointwise mutual information), tc-lcp (normalized log conditional probability), and tc-nz (number of topic word pairs never observed together in the corpus) that have been introduced by boyd-graber, mimno, and newman; bouma; and lau, newman, and baldwin.24 these three metrics are based on the assumption that the likelihood that two words that co-occur in a topic would also co-occur within a corpus. to utilize the three topic coherence metrics, the study chose a binarized choice (e.g., does a transcript contain two words?) instead of a sliding window of fixed size (e.g., do two words appear within a fixed window of 10 consecutive words?) as a type of how to count term cooccurrences. this decision was made because each chat transcript is relatively short, and a fixed information technology and libraries september 2021 topic modeling as a tool for analyzing library chat transcripts | koh and fienup 9 window size seemed inconsistent across different type of data sets that included different parts of speech. in terms of the other decision to be made for applying the three topic coherence metrics, this study chose a training corpus of all the chat transcripts instead of external corpuses such as the entire collection of english wikipedia articles that has little in common with average library chat transcripts. qualitative evaluation with human judgment in addition to quantitative evaluation with topic coherence metrics, qualitative accuracy and interpretability were judged by the librarian author of this paper based on whether topics were aligned with frequently asked questions or easily inferable themes in academic library contexts. for example, “find or access book or article” was inferred, from a set of words in topic 1 on lsa in table 6, as an accurate and easily interpretable theme. from a set of words in topic 3 on lda, “reserve study room” and “check out laptop computer” were inferred as two separable, easily interpretable themes. from a set of words in topic 15 on corex with nine anchors, no theme was inferred as an easily interpretable theme.

coherence metrics given that for a topic coherence metric tc-pmi larger values mean more coherent topics, table 7 and its corresponding figure 1 show that corex with anchor words on the whole-chat performed best on tc-pmi. tf–idf & plsa on the whole-chat performed better than lda on the whole-chat. given that for topic coherence metric tc-lcp larger values mean more coherent topics, table 8 and its corresponding figure 2 show that dmm on the whole-chat performed best on tc-lcp. tf– idf & plsa on the whole-chat performed better than lda, even though lda (pymallet) on the whole-chat performed better than tc-idf & plsa on the whole-chat. given that for topic coherence metric tc-nz smaller values mean more coherent topics, table 9 and its corresponding figure 3 show that tf–idf & plsa, lda

whole-chat data set with all parts of speech was generally the best data set on all the techniques. qualitative evaluation with human judgment as shown in table 10, all techniques had relatively high accuracy and interpretability in terms of straightforward topics or themes in italicized text, such as “interlibrary loan,” “technology,” “hours,” and “room reservations,” where one keyword could represent a whole theme. however, in terms of less-straightforward topics or themes plsa performed better than the other techniques. in other words, plsa had the highest number of topics that are aligned clearly with frequently asked questions or are easily inferable themes in academic library contexts. also, plsa had a lower number of unrelated or multiple themes within one topic, whereas other techniques had a higher number of unrelated or multiple themes within one topic. as an example, topic 8 on dmm shows that “print” and “citation” can be inferred as two unrelated themes within one topic. table 10. examples of themes qualitatively inferred from a list of words (a topic) identified by each topic modeling technique topic modeling technique themes inferred from table 6 (note:

performed the best depending on different types of topic coherence metrics, it is not possible to make a firm conclusion that one technique is better than the others. interestingly, the commonly-used technique lda tested in both sklearn and pymallet in this study did not consistently outperform tf–idf & plsa. in addition, semisupervised techniques of anchored correlation explanation (corex) or guided lda (guidedlda) did not necessarily outperform an unsupervised technique of the dirichlet multinomial mixture (dmm). last, from a human’s qualitative judgment, plsa performed the best, which is aligned with the findings on tc-nz. this might imply that tc-nz is a more appropriate metric than the other metrics in measuring topic coherence in the context of academic library chat transcripts. in terms of different types of data sets, all three of the whole-chat data sets significantly outperformed the questions-only data set. at the outset of the study, it was conjectured that the initial question of each chat transaction might concentrate the essence of each chat, thereby leading to better performance. clearly this was not the case, possibly because the rest of chat transcripts would reinforce a topic by standardizing the vocabulary of the chat’s initial question. it was somewhat interesting that varying the parts of speech (pos) retained in the three whole-chat data sets had little benefit on the topic modeling analyses. it might imply that topic modeling information technology and libraries september 2021 topic modeling as a tool for analyzing library chat transcripts | koh and fienup 20 techniques are sensitive enough to differentiate across different parts of speech, thereby leading to good performance regardless of types of data sets. conclusion this study clearly showed that conventional techniques should be also examined to avoid any errors from the assumption that newly developed techniques such as lda would always outperform regardless of contexts. also, both quantitative and qualitative evaluations indicate that unsupervised techniques should be equally weighted as semi-supervised techniques with human interventions. as a future study, like other similar research, it would be meaningful to compare human qualitative judgment with scores of each metric more rigorously, along with more librarians’ input, to confirm (or disconfirm) our preliminary conclusion that tc-nz is the most appropriate topic coherence metric in the context of library chat transcripts.25 it would be also interesting to investigate and examine semi-supervised techniques with different types of anchoring approaches, such as tandem anchoring.26 last, in order to overcome limitations of this study, it would be valuable to collect more and diverse chat reference data and compare output of topics across different types of institutions (e.g., teaching versus research institutions). acknowledgments this project was made possible in part by the institute of museum and

information technology and libraries | march 2017 36 abstract tv white space (tvws) represents one new wireless communication technology that has the potential to improve internet access and inclusion. this primer describes tvws technology as a viable, long-term access solution for the benefit of public libraries and their communities, especially for underserved populations. discussion focuses first on providing a brief overview of the digital divide and the emerging role of public libraries as internet access providers. next, a basic description of tvws and its features is provided, focusing on key aspects of the technology relevant to libraries as community anchor institutions. several tvws implementations are described with discussion of tvws implementations in several public libraries. finally, consideration is given to first steps that library organizations must take when contemplating new tvws implementations supportive of wifi applications and crisis response planning. introduction tens of millions of people rely wholly or in part on libraries to provide access to the internet. many lack access to the federal communications commission (fcc) recommended standard of 25 mbps (megabits per second) download speed and 3 mbps upload speed.1 though the fcc reclassified high-speed internet as a public utility under title ii of the telecommunications act to ensure that broadband networks are “fast, fair, and open” in 2015,2 the “digital divide” still remains. one in four community members does not have access to the internet at home. accounting for age and education level, households with the lowest median income households have service adoption rates of around 50%, compared to those with higher incomes, with rates of 80 to 90%.3 a recent pew research center survey on home broadband adoption found that 43% of those surveyed reported cost being their main reason for non-adoption.4 individuals with low quality or no access are more likely to be digitally disadvantaged, tend to use library computers more frequently, and are less equipped to interact and compete economically as more services and application processes move online.5 kristen radsliff rebmann (kristen.rebmann@sjsu.edu) is associate professor, san jose state university school of information, san jose, ca. emmanuel edward te (emmanueledward.te@sjsu.edu) is a

white spaces in public libraries: a primer | rebmann, te, and means | https://doi.org/10.6017/ital.v36i1.9720 37 this article highlights tv white space (tvws), a new wireless communication technology with the potential to assist libraries in addressing digital access and inclusion issues. this primer provides first a brief overview of the digital divide and the emerging role of public libraries as internet access providers, highlighting the need for cost-efficient, technological solutions. we go further to provide a basic description of tvws and its features, focusing on key aspects of the technology relevant to libraries as community anchor institutions. several tvws implementations are described with discussion of how tvws was set up in several public libraries. finally, we extend consideration to first steps library organizations must consider when contemplating new implementations including everyday applications and crisis response planning. digital access and inclusion the term “digital divide” describes the gap between people who can easily access and use technology and the internet, and those who cannot.6 as kinney observes, “there has not been one single digital divide, but rather a series of divides that attend each new technology.”7 digital divides are exacerbated by various factors including: socioeconomic status, education, geography, age, ability, language, and especially availability and quality.8 in recent years, the language describing this issue has changed, but the inequalities stay consistent and widen among different dimensions with each emerging technology. the most recent public policy term “digital inclusion” promotes digital literacy efforts for unserved and underserved populations.9 the progression from the term “digital divide” to “digital inclusion” represents a shift in focus from issues of access exclusively toward contexts and quality of participation and usage. along these lines, the language of digital inclusion reframes the issue by making visible that simply focusing on internet access can obscure the fact that divides associated with quality and effectiveness remain.10 in response to the digital divide, public libraries have become the “unofficial” providers of internet access, stemming from libraries’ access to broadband infrastructure, maintenance of publiclyavailable computers, and services providing assistance and training.11 a pew research center survey on perceptions of libraries found that most respondents reported viewing public libraries as important parts of their communities, providing resources and assisting in decisions regarding what information to trust.12 however, many public libraries are facing an “infrastructure plateau” of internet access due to few computer workstations and slower broadband connection speeds that can support a growing number of users,13 on top of insufficient funding, physical space, and staffing.14 previous surveys show that although public libraries are connected to the internet and provide public access workstations and wireless access, nearly 50% of public libraries only offer wireless access that shares the same bandwidth as their workstations.15 this increased usage strains existing network connections and infrastructure, resulting in slower connections for everyone connected to the public library’s network. many public libraries cannot accommodate more workstations, support the power requirements of both workstations and patrons’ laptops, and afford workstation upgrades and bandwidth increases to move past their insufficient connectivity speeds. libraries often lack the it skills, time, and funds to upgrade their information technology and libraries | march 2017 38 infrastructure.16 typical wireless access via wi-fi is relegated to distances within library buildings, which may extend to exterior spaces and is available only during operating hours. despite these challenges, public libraries continually provide access and “at-the-point-of-need” training and support for their patrons, especially for those who do not have easy access to the internet and computers.17 subsidized by federal funding, libraries represent key access providers and technology trainers for the public without internet access.18 the fcc classifies libraries as “community anchor institutions” (cais), organizations that “facilitate greater use of broadband by vulnerable populations, including low-income, the unemployed, and the aged.”19 recent surveys show that users have a positive view of libraries, providing opportunities to spend time in a safe space, pursue learning, and promote a sense of community. librarians offer internet skills training programs more often than other community organizations though (at around 75% of the time) training occurs informally.20 in particular, 29% of respondents to a library use survey reported going to libraries to use computers, the internet, or the wi-fi network; 7% have also reported using libraries’ wi-fi signals outside when libraries are closed.21 the majority of these users are more likely to be young, black, female, and lower income, utilizing library technology resources for school or work (61%), checking email or sending texts (53%), finding health information (38%), and taking online courses or completing certifications (26%).22 public libraries are already exploring creative approaches to providing internet access for these underserved communities. the mobile hotspot lending program in public library systems in new york city and kansas city are just two examples.23 yet libraries must do more by supporting innovation and providing leadership by partnering with other community organizations and their stakeholders to enhance resilience in addressing access and inclusion. the emergence of tvws wireless technology presents an opportunity for libraries to explore expanding the reach of their wireless signals beyond library buildings and extend 24/7 library wi-fi availability to community spaces such as subsidized housing, schools, clinics, parks, senior centers, and museums. tvws basics tv whitespace (tvws) refers to the unoccupied portions of spectrum in the vhf/uhf terrestrial television frequency bands.24 television broadcast frequency allocations traditionally assumed that tv station transmissions operating at high power needed wide spectrum separation to prevent interference between broadcasting channels, which led to the specific spectrum allocation of these frequency “guard bands.”25 research discovered that low-power devices can operate within these spaces, which led the federal communications commission (fcc) to field test tvws applications to wireless communications and (ultimately) promote tvws neutrality.26 in 2015, the federal communications commission (fcc) made a portion of these very valuable tvws bands of spectrum available for open, shared public use, like wi-fi. yet, unlike wi-fi, with a reach measured in 10s of meters, the range of tvws is measured in 100s or even 1000s of meters. tvws has good propagation characteristics, which makes it an extremely valuable license-exempt radio spectrum.27 it is a relatively stable frequency that does not change over time, allowing for tv white spaces in public libraries: a primer | rebmann, te, and means | https://doi.org/10.6017/ital.v36i1.9720 39 spectrum availability estimates to remain reliable and valid, which in turn promotes its various applications.28 radio spectrum is considered a “common heritage of humanity,”29 as radio waves “do not respect national borders.”30 the fcc recently made a portion of these tvws bands of spectrum available for open, shared public use.31 tvws availability and application are contextual and dependent on many key factors. availability is influenced by frequency (the idle channels purposely planned in tv bands, varying across regions), deployment (the height and location of the tvws transmit antenna and its installation sites in relation to nearby surrounding tv broadcasting reception), space and distance (geographical areas outside the current planned tv coverage, including no present broadcasting signals), and time (off-air availability of licensed broadcasting transmitters during specific periods of time, subject to change by the broadcaster).32 as tvws existed as fragmented “safety margins” between broadcast services, tvws is typically more abundant in rural areas that have less broadcast coverage and in larger contiguous blocks rather than in highly dense urban areas.33 assigned spectrum is not always used efficiently and effectively by licensees, and exclusive or nonexclusive sharing can alleviate pressure on these resources.34 this “spectrum crunch” of the inefficient use of scarce spectrum resources can be alleviated with dynamic spectrum access (dsa) and spectrum sharing. tvws availability is small where digital television has been deployed, with the potentials for aggregate interference (from tvws users in relation to primary tv service) and self-interference (within the tvws network), which may lead to a “mismatch situation” where there is high demand for bandwidth but very low tvws bandwidth supply.35 as most spectrum frequencies have been organized through some form of exclusive access in which only the licensee can use the specific spectrum, technologies such as cognitive radios can enable new modes of spectrum access, supporting autonomous, self-configuring, self-planning networks which rely on up-to-date tvws availability databases. the limited distribution (in many areas) of basic broadband infrastructure and relatively high cost of access often prevents individuals with lower incomes from participating in the digital revolution of information access and its opportunities.36 despite these challenges to broadband availability, tvws excels in areas with low broadband coverage. rural regions possess greater frequency availability due to lower density of spectrum licensing. in comparison to other frequencies operating higher up on the spectrum band, tvws does not require direct line-of-sight between devices for operation, and has lower deployment costs. equipment market costs are comparable to wi-fi equipment currently on the market.37 importantly, tvws can address access and inclusion by having relatively low start-up costs and no ongoing services fees. as a public resource, it can work with existing services to create new, potentially mobile connections to the internet that ensure the continuation of vital services in the event of service interruptions.38 in urban areas with fewer channels available, new efficient spectrum sharing policies will be necessary. assigned spectrum is not always used efficiently and effectively by licensees, and exclusive or non-exclusive sharing or “recycling” of bands for more information technology and libraries | march 2017 40 effective spectrum use by multiple parties with changing spectrum needs can alleviate pressure on these resources.39 tvws for public libraries tvws is a viable medium for applications from internet access, content distribution within a given location, tracking (people, animals, and assets), task automation, and public safety and security,40 as well as remote patient monitoring and other telemedicine applications.41 tvws complements existing networks that use other parts of the spectrum for access points, mobile communications, and home media devices.42 analyses of a recent digital inclusion survey suggest that technology upgrades can have significant impact on the ability of libraries to expand programs and services.43 as community anchor institutions (cais), public libraries can use tvws systems to expand and improve access to their services for their users, especially for underserved populations. library-led collaborations to deploy tvws networks in other cais and public spaces have numerous benefits. in conjunction with building-centered wi-fi, tvws can redistribute network users from congested library spaces to other community sites, thereby distributing network usage across the community. from an existing broadband connection, libraries can extend their networks of internet access strategically across their communities. yet, unlike networks which solely use limited-range wi-fi, far-reaching tvws can improve the coverage and inclusion of patrons in accessing library programs, services and the broader internet.44 the portability of the access points allows libraries to extend their reach by providing wireless connections in the shortterm, for cultural or civic events like fairs, markets, or concerts, and in the long-term, for use at popular public areas. recent tvws pilot installations have proven to be very stable in kansas, colorado, mississippi, and delaware. manhattan public library (kansas)’s tvws project began in fall 2013. though there were a few delays in the installation and testing process, the tvws equipment was successfully implemented and welcomed by the community in early 2014. it staff report that their remote locations have shown that this library service fills a community need, especially for underserved populations.45 delta county libraries (colorado) are conducting trials with two public hotspots to support “guest” access and potentially provide library patrons with more bandwidth access.46 tvws implementations in the pascagoula school district (mississippi)47 and delaware public libraries48 show successful initial pilot usage in providing wireless internet service directly to community-distributed access points. though there are contextual differences across these sites, the strength of public libraries as cais providing internet access via tvws systems is evident and promising. first steps any library can take the initiative in setting up a tvws network on its own. the first step is to assess availability of spectrum in the library’s geographic location. access to tvws frequencies is free and requires no subscription fees other than the initial equipment investment. public tv white spaces in public libraries: a primer | rebmann, te, and means | https://doi.org/10.6017/ital.v36i1.9720 41 databases of tvws availability are easily accessible and have been tested by the fcc since 2011;49 google also has posted its own spectrum database as well.50 from this setup, the library gains access to public tvws frequencies by which they can broadcast and receive internet connections from paired tvws-enabled remote hotspots. once it is determined that there is available spectrum/channels in the desired area, libraries can then explore how their current broadband and wireless connections might be expanded to include several community spaces where internet access is needed. next, the library works with a tvws equipment supplier to design and install a tvws network consisting of a base station that is integrated with their wired connection to the internet. finally, the library places tvws-enabled remote hotspots in (previously identified) community-based spaces where wi-fi access is needed by underserved populations. given a high quality backhaul (i.e., fiber optic cable high speed connection), tvws can spread that signal and provide access from the library, which is able to propagate and penetrate multiple barriers and geographical features with a signal up to 10 times stronger than current wi-fi. depending on the context (geographical features, tvws availabilities, etc.), hotspots can be installed up to six miles (10 km) away and do not require line-of-sight between the base station and hotspots. this ability is superior to current wi-fi networks that only cover patrons in the immediate vicinity of the library. these tvws remote hotspots also can be easily (and strategically) moved to support occasional community needs (such as neighborhood-wide or city events) or in response to crisis situations. tvws, libraries, and emergency response public libraries provide leadership as “ready access point, first choice, first refuge, and last resort” for community services in everyday matters and in emergencies.51 they have assisted residents in relief efforts during hurricanes katrina and rita, and other natural and man-made disasters.52 …the provision of access to computers and the internet was a wholly unique and immeasurably important role for public libraries… the infrastructure can be a tremendous asset in times of emergencies, and should be incorporated into community plans.53 they have likewise provided immediate and long-term assistance to communities and aid workers, providing physical space for recovery operations for emergency agencies, communication technologies, and emotional support for the community. in previous library internet usage surveys, nearly one-third of libraries reported that their computers and internet services would be used by the public in emergencies to access relief services and benefits.54 such activities include finding and communicating with family and friends, completing online fema forms and insurance claims, and checking news sites regarding information of their affected homes.55 yet, despite the admirable and successful efforts of many public libraries, their infrastructures are not always built to meet the increased demand of user needs and e-government services in emergency contexts.56 jaeger, shneiderman, fleischmann , preece, qu, and wu propose the concept of community response grids (crgs), which utilize the internet and mobile communications devices so that emergency responders and residents in a disaster area can information technology and libraries | march 2017 42 communicate and coordinate accurate, appropriate responses.57 this concept relies on social networks, both in person and online, to enable residents and emergency responders to work together in a multi-directional communication scheme. crgs provide residents tailored, localized information and a means to report pertinent disaster related information to emergency responders, who in turn can synthesize and analyze submitted information and act accordingly.58 due to their existing role as community anchor institutions (cais), public libraries are uniquely positioned for crg involvement. libraries can assist in facilitation of internet access with portable tvws network connection points. by virtue of their portability, tvws hotspots can provide essential digital access in times of crisis by moving along with their affected populations. emergency operations and communications in a crisis occur throughout networks comprised of various technologies. information management before, during, and after a disaster affects how well a crisis is managed.59 broadband internet can be one access route in the event that phone and radio transmissions are affected, and vice versa, as part of a “mixed media approach” to get messages to those that need it in an emergency.60 yet one must remember that internet communications are double-edged: the internet provides relevant material on demand and near instant sharing and collaborating, but these very features can compound a crisis with misinformation.61 despite these concerns, the potential of the integration of wireless devices and other technologies into a multi-technology, collaborative response system can solve the problem of existing communication structures that lack coordination and quality control.62 the proliferation of smartphones, laptops, and other portable wireless devices makes such technology ideal for emergency communications, especially in how users’ familiarity with their own devices will help them navigate crg communications while under stress.63 conclusion supporting internet access and inclusion in public libraries and having equal, affordable, and available access to information is a necessary component to bridging the digital divide. technology has become “an irreducible component of modern life, and its presence and use has significant impact on an individuals’ ability to fully engage in society.”64 as cohron argues, this principle represents more than providing people with internet access: it is about “leveling the playing field in regards to information diffusion. the internet is such a prominent utility in peoples’ lives that we, as a society, cannot afford for citizens to go without.”65 broadband access is the first step; digital literacy training is also a necessity. access alone is not enough to ensure quality and effective use, however, as the digital divide is representative of broader social inequalities that computer and internet access cannot fully remedy.66 this is a complex problem that requires a multi-faceted solution. as kinney states, “the digital divide is a moving target, and new divides open up with new technologies. libraries help bridge some inequities more than others, and substantial disparities exist among library systems.”67 internet access also becomes a necessity when the internet is to play a role in emergency communications.68 tv white spaces in public libraries: a primer | rebmann, te, and means | https://doi.org/10.6017/ital.v36i1.9720 43 it is problematic to suggest that public libraries can be simultaneously promoted as the solution to digital divide issues while facing cuts to funding. policy makers, community advocates, and the community members themselves are stakeholders in the success of their communities, and must also take responsibility for access and inclusion via public libraries.69 as public agencies automate to increase equality and save money, they exacerbate digital divides by excluding those without access. suggesting that community members simply visit the library to ensure access to public services places additional pressure on libraries, yet these efforts may go unsupported and unacknowledged. public libraries are already valuable community access points to resources especially in emergencies, though many suffer from a lack of concerted disaster planning. along similar lines, many libraries are ill-equipped to accommodate the bandwidth needs of growing and oftentimes sparsely connected populations. as communications and government services move increasingly online, it becomes imperative to build strong cost-effective information infrastructures. tvws connections can arguably help in breaking down the barriers that challenge ubiquitous access and inclusion. tvws-enabled remote access points in daily use around communities are ideally situated to provide everyday wi-fi and for rapid redeployment to damaged areas (as pop-up hotspots) to provide essential communication and information resources in times of crisis. in short, tvws can augment the technological infrastructure of public libraries toward further developing their roles as cais and leaders serve their communities well into the future. references 1. wireline

for lita that means some exciting things! the program planning committee is hard at work evaluating the sixty-plus program proposals that have been submitted. the new conference format specified by ala means that we have 20 slots for lita programs at annual, including the president's program and top tech trends. the ppc certainly has its work cut out! well before midwinter in philadelphia will be national forum 2013. i'm so excited that this year's forum is going to be in my home state of kentucky. join us from november 7-10 in "luhvuhl" (louisville) for great keynotes, preconference workshops, concurrent sessions, and of course, networking opportunities. travis good from make magazine will deliver our opening keynote, nate hill from chattanooga public library is up on saturday, and emily gore from the digital public library of america closes out the forum on sunday. i hope you'll join us for an exciting forum in the bluegrass state. in governance news, the board of directors identified three goal areas on which we will concentrate this year: stabilizing the budget, engaging members, and growing membership. we are eagerly awaiting the final report of the financial stability task force, led by tom wilson and andrew pace; they presented preliminary findings at the board meeting in chicago in july. we are currently updating the strategic plan, which was last updated in 2010—watch the lita-l list and the blog for more. we would love your input on them! if you're interested in lita governance, check out the board's space on ala connect. many discussion posts are open, and we welcome your comments! you can also complete this form (http://www.ala.org/lita/about/board/contact) to reach out to the board anytime. the board will be having several meetings this fall: the executive committee is tentatively meeting september 30; the forum steering committee will meet after forum 2013; the budget review committee will be meeting at the ala joint boards meeting in late october; and the entire board will have an online meeting before we convene in person in philadelphia. watch lita-l for the announcements; we welcome you as guests to all our meetings. finally, for those of you interested in leadership but not necessarily ready to run for board, i want to point you to documents put together by the lita emerging leaders team in 2013: http://connect.ala.org/node/197839 our team of three ala emerging leaders, margaret heller, zach coble, and katie heidgerkengreene, surveyed lita leaders, worked with committee chairs coordinator michelle frisque and ig chairs coordinator paul keith, and synthesized tons of information and many documents into the leadership guide for new chairs of committees and interest groups cindi trainor

is lita president 2009–10 and head, information systems, north western university, chicago. b y the time you read this column i will be lita president, however, as i write this i still have a couple of weeks left in my vice-presidential year. i have been warned by so many that my presidential year will fly by, and i am beginning to understand how that could be. i can’t believe i am almost done with my first year. i have enjoyed it and sometimes been overwhelmed by it—especially when i began the process of appointing lita volunteers to committees and liaison roles. i didn’t realize how many appointments there were to make. i want to thank all of the lita members who volunteered. you really helped make the appointment process easier. as a volunteer organization, lita relies on you, and once again many of you have stepped up. thank you. during the appointment process i was introduced to many lita members whom i had not yet met. i enjoyed being introduced to you virtually, and i look forward to meeting you in person in the coming year. i also want to thank the lita office. they were there whenever i needed them. without their assistance i would not have been able to successfully complete the appointment process. over the last year i have been working closely with this year’s lita emerging leaders, lisa thomas and holly tomren. i have really enjoyed the experience. their enthusiasm and energy is contagious. i wish every lita member could have been at this year’s lita camp in columbus, ohio, on may 8. during one of the lightning round sessions, lisa went to the podium and gave an impassioned speech about the benefits of belonging to a professional organization like lita. if there was a person in the audience that was not yet a lita member, i am sure they joined immediately afterward. she really captured the essence of why i became active in lita and why i continue to stay so involved in this organization so many years later. i can honestly say that as much as i have given to lita, i have received so much more in return. that is the true benefit of lita membership. over the last year, the lita board has had some great discussions with lita members and leaders. those conversations will continue as we start the work of drafting a new strategic plan. i want to create a strategic plan that will chart a meaningful path for the association and its members for the next several years. i want it to provide direction but also be flexible enough to adapt to changes in the information technology association landscape. as andrew pace mentioned in his last president’s message, changes will be coming. while we still aren’t sure exactly what those changes are, we know that it is time to seriously look at the current organizational structure of lita to make sure it best fits our needs today while continuing to remain flexible enough to meet our needs tomorrow. when i think of the organizational changes we are exploring, i can’t help but think of the houses i see on my favorite home improvement shows. lita has good bones. the structure and foundation are solid and well built, and as long as the house is well cared for, should last for years to come. however, like all houses, improvements need to be made over time to keep up with the market. the lita structure and foundation will be the same. when you drive up to the house you will still recognize the lita structure. when you walk in the door my hope is that you will still get that same homey feeling you had before, maybe with a few “oohs” and “aahs” thrown in as you notice the upgrades and enhancements. as the year progresses we will know more. i will use this column and other communication avenues to keep you informed of our plans and to gather your input. i would like to close my first column by thanking you for giving me this opportunity to serve you as the lita president. i am honored and humbled by the trust you have placed in me, and i am ready to start my presidential year. i hope it does not go by too quickly. i want to savor the experience. now let’s get started! 50 information technology and libraries | june 2009 andrew k. pace president’s message: lita forever andrew k. pace (pacea@oclc.org) is lita president 2008/2009 and executive director, networked library services at oclc inc. in dublin, ohio. i was warned when i started my term as lita president that my time at the helm would seem fleeting in retrospect, and i didn’t believe it. i should have. i suppose most advice of that sort falls on deaf ears—advice to children about growing up, advice to newlyweds, advice to new parents. some things you just have to experience. now i am left with that feeling of having worked very hard while not accomplishing nearly enough. it’s time to buy myself some more time. my predecessor, mark beatty, likes to jokingly introduce himself in ala circles as “lita has-been” in reference to his role as lita past-president. i say jokingly because he and i both know it is not true. not only does the past-president continue in an active role on the lita board and executive committee, the past-president has the daunting task of acting as the division’s financial officer. just as mark knows well the nature of this elected (but still volunteer) commitment, so michelle frisque, my successor this july, knows that the hard work started as vice-president/ president-elect has two challenging years ahead. being elected lita president is for all intents and purposes a three-year term with shifting responsibilities. add to this the possibility of serving on the board beforehand, and it’s likely that one could serve less time for knocking over a liquor store. i’m joking, of course— there’s nothing punitive about being a lita officer; it’s as rewarding as it is challenging. neither is this intended to be a self-congratulatory screed as my last hurrah in print as lita president. i’ve referred repeatedly to the grassroots success of lita’s board, interest groups, dedicated committees, and engaged volunteers. the flatness of our division is often emulated by others. i thoroughly enjoy engagement with the lita membership, face-to-face and virtual recruitment of new members and volunteers, and group meetings to discuss moving lita forward. i love that lita is fun. fun and enjoyment, coupled with my dedication to the profession that i love, is why i plan to make the most of my time, even as a has-been. all those meetings, all that bureaucracy? well, believe it or not, i like the bureaucracy—process works when you learn to work the process—and all those meetings have actually created some excellent feedback for the lita board. changes in ala, changes in the membership, and changes suggested by committees and interest groups all suggest . . . guess what? change. “change” has been a popular theme these days. i’m in that weird minority of people who does not believe that people don’t like to change. i think if the ideas are good, if the destination is worthwhile, then change is possible and even desirable. i’m always geared up for change, for learning from our mistakes, for asking forgiveness on occasion and for permission even less. this is a long-winded way of saying that i think lita is ready for some change. change to the board, change to the committees and interest groups, and changes to our interactions with lita and ala staff. i think ala and the other divisions are anxious for change as well, and i feel confident that lita and its membership can help, even while we change ourselves. don’t ask me today what the details of these changes are. all i can say is that i will be there for them, help see them through, and will be there on the other side to asses which changes worked and which didn’t. one thing i hope does not change is the passion and dedication of the leaders, volunteers, and members of this great organization. i only hope that our ranks grow, even in times of financial uncertainty. lita provides a valuable network of colleagues and friends—this network is always valuable, but it is indispensible in times of difficulty. for many, lita represents a second or third divisional membership, but for networking and collegial support, i think we are second to none. i titled my previous column “lita now.” i think it’s safe for me to say now, “lita forever.” microsoft

 activities.   the  national  forum  2015  will  be  here  before  you  know  it.    in  a  fall  season  crowded  with  good   technology  conferences,  lita  forum  consistently  proves  its  value  as  a  small,  engaging,  and   focused  meeting.    technologists,  strategists,  and  front-­‐line  librarians  come  together  to  discuss  the   tools  they  make  and  use  to  provide  cutting

tinuing education opportunities for library information technologists and all library staff who have an interest in technology. 2. innovation: to serve the library community, lita expert members will identify and demonstrate the value of new and existing technologies within ala and beyond. 3. advocacy and policy: lita will advocate for and participate in the adoption of legislation, policies, technologies, and standards that promote equitable access to information and technology. 4. the organization: lita will have a solid structure to support its members in accomplishing its mission, vision, and strategic plan. 5. collaboration and outreach: lita will reach out and collaborate with other library organizations to increase the awareness of the importance of technology in libraries, improve services to existing members, and reach out to new members. the lita executive committee is currently finalizing the strategies lita will pursue to achieve success in each of the goal areas. it is my hope that the strategies for each goal are approved by the lita board of directors before the 2010 ala annual conference in washington, d.c. that way the finalized version of the lita strategic plan can be introduced to the committee and interest group chairs and the membership as a whole at that conference. this will allow us to start the next fiscal year with a clear road for the future. while i am excited about what is next, i have also been dreading the end of my presidency. i have truly enjoyed my experience as lita president, and in some way wish it was not about to end. i have learned so much and have met so many wonderful people. thank you for giving me this opportunity to serve you and for your support. i have truly appreciated it. a s i write this last column, the song “my way” by frank sinatra keeps going through my head. while this is definitely not my final curtain, it is the final curtain of my presidency. like sinatra i have a few regrets, “but then again, too few to mention.” there was so much more i wanted to accomplish this year; however, as usual, my plans were more ambitious than the time i had available. being lita’s president was a big part of my life, but it was not the only part. those other parts—like family, friends, work, and school—demanded my attention as well. i have thought about what to say in this final column. do i list my accomplishments of the last year? nah, you can read all about that in the lita annual report, which i will post in june. tackle some controversial topic? while i can think of a few, i have not yet thought of any solutions, and i do not want to rant against something without proposing some type of solution or plan of attack. i thought instead i would talk about where i have devoted a large part of my lita time over the last year. as i look back at the last year, i am also thinking ahead to the future of lita. we are currently writing lita’s strategic plan. we have a lot to great ideas to work with. lita members are always willing to share their thoughts both formally and informally. i have been charged with the task of taking all of those great ideas, gathered at conferences, board meetings, hallway conversations, surveys, e-mail, etc., to create a roadmap for the future. after reviewing all of the ideas gathered over the last three years, i was able to narrow that list down to six major goal areas. with the assistance of the lita board of directors and the lita executive committee, we whittled the list down to five major goal areas of the lita strategic plan: 1. training and continuing education: lita will be nationally recognized as the leading source for conmichelle frisque (mfrisque@northwestern.edu) is lita president 2009–10 and head, information systems, north

directory and subrecord relationship fields in the proposed american standard for a format for bibliographic information interchange on magnetic tape the following appendix is not part of the proposed standard but is included to illustrate a method for handling subrecords within a bibliographic record. 1. subrecord directory a subrecord directory will be used when a bibliographic record consists of more than one subrecord. the subrecord directory, when present, will contain entries comprising a directory of the directory entries. 0 1.1 entries in subrecord directory tag id the format of each entry in the subrecord directory is as shown: 1 tag length starting character type-ofbibliographic position record level 2 3 6 7 11 1.1.1 tag the tag is associated with a complete subrecord. 1.1.1.1 tag id the tag id is a data element consisting of one basic character used to differentiate tags for multiple subrecords describing bibliographic units which have the same type-of-record and bibliographic level codes (see 3.2.4 and 3.2.5). 1.1.1.2 type-of-record and bibliographic level when the subrecord does not describe a primary bibliographic unit, the type-of-record and bibliographic level are assigned as though it did. appendix ii 95 1.1.2 length of subrecord directory the length of that portion of the directory associated with the subrecord. (this value is always a multiple of twelve and when divided by twelve, equals the number of entries associated with the subrecord.) 1.1.3 starting character position the starting character position is that of the first entry in the directory which pertains to the subrecord. it is ·a five-digit decimal number relative to the first character of the bibliographic record. 2. subrecord relationship field a subrecord relationship field will be present if, and only if, a subrecord directory is present. the subrecord relationship field, when present, shall contain fixed fields which are used to indicate the relationships of subrecords to each other. 2.1 relationship fields the format of each relationship field is as shown : i tag i relationship indicator i tag i tag i 0 2 3 5 6 8 9 11 if a subrecord bears the same relationship to two subrecords, they may both be shown, otherwise the second tag field is padded with the padding character. there is no limit to the number of relationship fields or to the number of relationships which may involve a specific subfield. the relationship fields may be used to develop, and define tags for, hierarchies of subfields. one bibliographic record may contain no more than 64 subrecords with the same type-of-record and bibliographic level. 2.1.1 tag the tags in the subrecord relationship field have the same format as those in the subrecord directory. 2.1.2 relationship indicator a relationship indicator is a data element consisting of three ( 3) basic characters used to indicate the relationship between subfields. the fourth industrial revolution: does it pose an existential threat to libraries? editorial board thoughts the fourth industrial revolution does it pose an existential threat to libraries? brady lund information technology and libraries | march 2021 https://doi.org/10.6017/ital.v40i1.13193 brady lund (blund2@g.emporia.edu) is a doctoral student at emporia state university's school of library and information management and a member of the ital editorial board. © 2021. “editorial board thoughts” is a regular column contributed by a member of the ital editorial board. opinions do not necessarily reflect those of the editorial board as a whole. no. no, it does not. not any more than any other technological innovation (information systems, personal computers, the internet, e-readers, google, google scholar) did. however, what is very likely is that the technologies that emerge from this era will slowly (but surely) lead to profound changes in how libraries operate. those libraries that fail to understand or embrace these technologies may, in fact, be left behind. so, we must, as always, stay abreast of trends in emerging technologies and what the literature (i.e., articles in this journal) propose as ideas for adopting (and adapting) them to better serve our patrons. with this column, my aim is to briefly discuss what the fourth industrial revolution is and its relevance within our profession. the “fourth” industrial revolution? the term “fourth industrial revolution” describes the evolution of information technology towards greater automation and interconnectedness. it includes or incorporates technological advancements such as artificial intelligence, blockchain, advanced robotics, the internet of things, autonomous vehicles, virtual reality, 3d printing, nanotechnology, and quantum computing.1 imaginations can run amok with idyllic visions of walt disney’s epcot—a utopian world of interconnectedness and efficiency—or dystopian nightmares captured in the mind of stephen king, george orwell, or pixar’s wall-e. if we have learned anything from the past though—and after the last 12 months i cannot be entirely sure of that—it is that reality is likely to settle somewhere in the middle. some things will improve dramatically in our lives but there will also be negative impacts—funding changes, learning curves, and maybe a bit of soul-searching within the profession (not that that last one is necessarily a bad thing). the “fourth industrial revolution” is referred to as such because historians of technological and industrial innovation have placed the period as fourth in a line of major shifts in technological innovation (shocking, no?). the first industrial revolution was the industrial revolution, the one we were taught to call the “industrial revolution” in high school: the period from the late-18th to mid-19th century where rapid innovation in the areas of agriculture and manufacturing transformed the economy, created a market for invention and profiteering, and formed a true “working class” of laborers. as idyllic as it sounds in our history classes, it was not a particularly pleasant time for the average laborer. there is a reason why the communist manifesto, and the whole concept of the social sciences, emerged from this era. but this era also brought us the modern (semi-modern?) library. mailto:blund2@g.emporia.edu information technology and libraries march 2021 the fourth industrial revolution | brady 2 the second industrial revolution, the “technological revolution,” occurred from the late-19th to early-20th century. it was all about the power of electricity and the engine. here we have the emergence of vast telegraph networks, lightbulbs, automobiles, and airplanes. very nice stuff. you also had a lot of economic uncertainty that led to a few depressions and wars (but do not focus on that too much, readers). the third industrial revolution, the “digital revolution,” is the first revolution that we really have a good record of within library and information science. it is why we have that “information science” part in the name. it is why we have this journal that you are reading now. it was the era of digital computers and computer networks. yes, it changed a lot—some for the better, some for the worse. if you are a reader of this journal, you would probably say—at least in terms of library services—that this era was full of fairly positive developments for libraries. we gained digital catalogs, electronic databases, integrated library systems, the internet, and microsoft office, all developments the increase the ease and efficiency of our everyday work tasks. so, that leads us to the precipice that we are on now. the fourth industrial revolution. while uncertainty provokes trepidation, there is much we can do to inform ourselves—much more so than with previous revolutions (we could not very well turn to the internet to learn about the internet). there are scenarios on both ends of the spectrum that ranges from utopia and doom — and it’s not altogether bad to read about the risks that automation presents, such as described by andrew yang and other political and economic figures—but if history and precedent mean anything, it is likely that we will see many things in our economy, and in our libraries, change substantially but certainly not vanish. the role of libraries in the fourth industrial revolution we have already been adopting many of these fourth industrial revolution technologies for quite some time—whether we were cognizant of it or not. a lot of what could be called “artificial intelligence” already exists in our library systems and more is on the way if current projects being conducted around the globe come to fruition.2 there are a lot of “pie in the sky” ideas of what the future of libraries will look like with the fourth industrial revolution—some of which were even published in this very journal. it is good to have these perspectives, even if they do seem a bit unrealistic and/or dystopian. we need to consider the possibilities of this era while also understanding the practicalities. our goal as library technologists—to serve the information needs of patrons to the best of our abilities—should never falter. if this is true of our professional ethics and values, then we must be prepared to sacrifice and adapt to change for the common good. one thing i am quite certain of is that these technological innovations will not spell doom for libraries. libraries are resilient and librarians themselves mean more to patrons than a computer interface. we do not have to go back too far to see how libraries responded to a similar disruptive period: the introduction of the internet. if you want to read an interesting parallel to this editorial, check out david raitt’s 1994 editorial in the electronic library (and hopefully not feel too old when you discover that i was born in the year that it was published). the purpose of raitt’s editorial was to answer the question that considering developments with the internet, “will librarians still be around in 2024, and if so what are they likely to be doing?”3 boy, i sure hope they are around in three years, or i really made a poor career choice. the ease with which raitt dismisses any concern about the internet spelling the end of libraries is delightful to read: “are librarians so insecure about their profession and future?... (in 2024) librarians will still be doing information technology and libraries march 2021 the fourth industrial revolution | brady 3 what they do now and what they have always done, only they will have more new-fangled technology to help them do it.”4 you could argue that raitt’s prediction is not entirely correct. some things about libraries have changed considerably. but have any of these changes been decidedly for the worse? even the most curmudgeonly postmodernist must concede that libraries serve their patrons better now than before the internet age. libraries, on the whole, are still very much the same. we have not undergone massive upheavals in our professional values and ethics. some job duties have changed (such as a greater emphasis on instruction in academic libraries) but it has not spelled total doom for our librarians. so, people, turn and face the strange, because there is nothing too serious to fear with coming changes. and, if my prediction turns out to be less accurate than raitt’s, well, just remember that my name is “john barron” (and metadata that indicates to the contrary is fake news). the changes that have been clumped under the buzzword of the “fourth industrial revolution” will do a lot to advance the mission of libraries. right now, a lot of the “how?” can seem a bit hazy, but check out some of these library school programs that are working to answer that very question and i think you will get a good idea: • blockchains for the information profession (san jose state university ischool): https://ischoolblogs.sjsu.edu/blockchains. o an imls-funded program that examines applications of blockchain in libraries. • artificial intelligence (a program of stanford university libraries): https://library.stanford.edu/projects/artificial-intelligence/. o a university-supported program that examines applications of ai in libraries. • the good systems program (university of texas ischool, in partnership with a bunch of other departments on campus): https://bridgingbarriers.utexas.edu/good-systems. o this program focuses on ethical uses of ai to improve lives. while it does not necessarily focus specifically on libraries, its founding members are connected to the university’s library school and many of the program’s “products” have direct relevance to libraries. library and information technology is one area where academia and scholarly research offer a lot of useful knowledge and ideas for the professional librarian. there are a lot of great ideas from researchers and programs at these schools, in addition to the investments made by industry leaders like oclc, that suggest libraries are not going to be left behind during the “coming revolution.”5 expect the ideas filtering from these programs, and others, to take greater hold in practical library settings in coming years—as the internet did in the mid-to-late 1990s and social media did in the period of (approximately) 2008–2013. like with these past innovations, the extent of adoption will likely vary from library-to-library. i will avoid a lecture on diffusion of innovations here, though it is one of my favorite “simple” theories (a few suggested readings for those who are interested are chatman’s 1986 article—which is a bit more technical—and minishi-majanja and kiplang'at’s 2005 article).6 what is important to expect is that this will not all just be a “flash in a pan” like we have seen before with some technologies. these technologies in the “fourth industrial revolution” will bring about real change in our world. if we are “ahead of the curve” (to reference a diffusion concept), we will be well-positioned to adapt to the changes to come. https://ischoolblogs.sjsu.edu/blockchains https://library.stanford.edu/projects/artificial-intelligence/ https://bridgingbarriers.utexas.edu/good-systems information technology and libraries march 2021 the fourth industrial revolution | brady 4 references 1 klaus schwab, the fourth industrial revolution (new york, ny: penguin books, 2017). 2 jason griffey, artificial intelligence and machine learning in libraries (chicago, il: american library association, 2019). 3 david raitt, “the future of libraries in the face of the internet,” the electronic library 12, no. 5 (1994): 275. 4 ibid. 5 thomas padilla, responsible operations: data science, machine learning, and ai in libraries (dublin, oh: oclc research, 2019), https://doi.org/10.25333/xk7z-9g97. 6 elfreda a. chatman, “diffusion theory: a review and test of a conceptual model in information diffusion,” journal of the american society for information science 37, no. 6 (1986): 377–86;

to offer the public access to the hardware, software, and bandwidth that they need to become successful. with this in mind we decided to turn our small conference room into a virtual interview lab. the room already had a good-sized table, excellent available wifi, generally good lighting, and plain white walls, perfect as a simple background. previous users of this room would generally use a laptop to connect to our wifi and a large screen in the room. instead, for this setup we added a small micropc which we connected via an ethernet port to our gigabit fiber internet connection. michael sauers (msauers@travelinlibrarian.info) is technology manager, do space, and a member of the journal’s editorial board © 2021. mailto:msauers@travelinlibrarian.info information technology and libraries june 2021 do space’s virtual interview lab | sauers 2 to this pc we added a 27” monitor, 1080p webcam, a blue yeti microphone, and headphones. on the pc we installed every virtual meeting platform we could think of including zoom, adobe connect, microsoft teams, gotowebinar/meeting, and more, placing direct shortcuts to all of the programs and online services right on the desktop for easy access. with our setup complete we opened the lab for bookings starting july 1, 2020. use has been slow and steady, possibly due to our low unemployment rate, but the members that have used it are grateful for its existence. our marketing was first just on our website and social media but after a month or two we gathered a list of over 50 area groups and organizations that assisted folks with finding work and mailed them a stash of postcards that they could hand out and asked them to let us know if they needed any more. one group was so inspired by the project that in their thank you they said that they’d be starting their own virtual interview lab at their location. in the past year the lab hasn’t changed all that much with the exception of moving to a different room and a broadening of the use case. we quickly realized that members were wishing to use the room for events beyond job interviews. those using the lab have done so for attending ged and language classes, business meetings, attending do space’s own online programming, and even participating in our virtual tech mentoring program. have there been any problems? we’re dealing with technology here so of course the answer is yes, but luckily, they have been minor. for example, one person commented that our blue headphones didn’t look as “professional” as they would have liked. other times zoom needed a last-minute update which staff quickly addressed. (we encourage everyone to book the start of their session 30 minutes in advance to give us a chance to fix such issues.) otherwise, feedback has been overall very positive. here’s just a few examples: • “thank you! i actually used the room on short notice for several conference calls (plumbing disaster at my house!). it's not the intended use, but it was open and your team was kind enough to let me use it. i sincerely appreciate it. the room, by the way, has an excellent set up. wifi was lightning fast, lighting was perfect and i love that you have a microphone to focus the sound. oh, and that cute coat rack dressed up my background when i had to talk to a large client. it's fantastic that you offer this resource to the community. thanks again for letting me use it!” • “wanted to note a few things. i used this space for a research interview where i was a participant. i wasn't strictly using this space for a job interview. that said, it suited my needs perfectly. i was very happy to utilize this space. it was quiet, clean, and accommodated what i was looking for. customer service was also excellent. the service desk worker was able to promptly get me set up when i was already running a bit late for my interview. thank you for making this service available and also making it intuitive and easy to utilize. i will probably look to use it again in the future.” • “the room is ideal, quiet, no distractions, i was able to connect clearly using teams, no glitches, the volume was loud enough. was able to hear clearly and see interviewers faces clearly. staff at do space were available and prompt to assist before the interview when i needed set-up help adjusting the appearance / display of my head within the frame/screen.” • “you are a godsend! i am so grateful, especially in these times, that you are here. the staff are kind, patient and thoroughly knowledgeable. i love you.” information technology and libraries june 2021 do space’s virtual interview lab | sauers 3 this experience has reminded me that while all the advanced experimenting and complex coding we create to better assist our users is all well and good, sometimes just a simple computer, internet connection, and webcam can make all the difference in someone’s life. while some of the changes that we’ve made over the past year, such as moving all programming online, will be either ending or slowly transitioning to pre-pandemic states, our virtual interview lab is one new service that we will be definitely keeping for the foreseeable future. jorgensen ฀ ฀ ฀ ฀ ฀ ฀ ฀฀ ฀฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀

yale university library, new haven, connecticut f. h. ruecking's word-compression algorithm for retrieval of bibliographic data from computer stores was tested for performance in matching usersupplied, unedited bibliographic data to the bibliographic data contained in a library catalog. the algorithm was tested by manual simulation, using data derived from 126 case studies of successful manual searches of the card catalog at sterling memorial library, yale university. the algorithm achieved 70% recall in comparison to conventional searching. its acceptability as a substitute for conventional catalog searching methods is questioned unless recall performance can be improved, either by use of the algorithm alone or in combination with other algorithms. frederick h. ruecking has published a report ( 1) of a method for improving bibliographic retrieval from computerized files when searching on unverified input data supplied by requestors. the method involves compression of author-and-title information before comparison. the rules for compression cause certain types of spelling errors and word discrepancies to be ignored by the computer. ruecking reported 90.4% recall and 98.67% accuracy (precision) in a test of his method in which unverified book order requests were matched against a marc i data base that contained 1392 of the references searched. this paper reports on a small-scale manual simulation test undertaken to assess the value of the method when applied to bibliographic retrieval from a library catalog. ruecking' s w ord-c ompression/ lipetz 267 the opportunity to test ruecking's method when applied to retrieval from a library catalog was provided by the ready availability of data derived from a current study ( 2) of catalog use at sterling memorial library (3.5 million books) at yale university. this study collects, from a rigidly randomized sample of catalog users, precise information on the clues available to them at the moment of initiating a search. search clues are recorded exactly as known to the catalog user, employing his own spelling-right or wrong. for each catalog user studied, the outcome of the search is ascertained; complete catalog information is recorded for documents identified as pertinent in successful searches. search clues known to catalog users wno seek specific documents correspond to the "unverified input data" which ruecking's method would match against catalog holdings. catalog information on those documents identified as pertinent corresponds to the portion of the data base that ruecking's program seeks to match. it was possible, therefore, to apply ruecking' s method by manual simulation, and to test its recall performance in real catalog searches. a test of its precision was not immediately feasible .because such a test would require comparison of input data with the entire catalog (or a substantial portion of it). however, the determination of recall performance would at least indicate whether the method shows sufficient promise in catalog searching to warrant evaluation of its precision. an aside on precision is in order, however. it should be noted that precision of retrieval with a given method tends to vary inversely with the size of the file being searched. although ruecking did not specify the number of records included in his marc i data base, it could not have exceeded 48,000. had he run his test on a data base, ten, or fifty, or one hundred times larger, the measured precision would certainly have been much lower than the figure reported. any librarian who is contemplating the adoption of a retrieval technique which has been tested on a data base similar to, but smaller than, his own should realize that precision performance must inevitably drop as the data base is increased. the degree of lowered precision to be expected may be predicted theoretically or estimated from tests on files of several different sizes. the data used in the evaluation of recall performance reported in this paper came from 126 searches in which the catalog users had been successful in locating the specific documents that they were seeking. the compression coding method described by ruecking was applied in each instance to the author-title search clues supplied by the catalog user and to the author-title information available on the catalog card. threshold values were computed for the catalog card data, and retrieval values were computed for the user data .. when the retrieval value was at least as large as the threshold value, the document was considered "retrieved." ruecking's method was designed for use with english-language titles only. of the 126 catalog searches in the study sample, 20 involved foreign268 journal of library automation vol. 2/ 4 december, 1969 language titles. recall was determined on both the full sample and the english-language subset of 106 searches. surprisingly, there is not a great improvement in performance when foreign-language references are excluded. it should be noted that several difficulties were encountered in applying ruecking' s method because of ambiguities in the rules stated in his paper. in fact, in his figure 2 (page 236), of the seventeen illustrations of compression-coded data retrieved by his program, at least eight appear to contain departures from the compression-coding rules as stated in the paper. his table 5 (page 235) is scantily described: "individual code test'' and "full-code test" are not defined; neither are column headings. and, contrary to the text (page 234), values in columns five through seven are obtained by adding two to the calculated thresholds in only the top half of table 5; in the bottom half, no such regular correlation exists. in all cases of ambiguity, the alternative was selected that would tend to increase probability of retrieval. for example, ruecking states (page 234) that the search program provided for matching of titles on the basis of rearrangement of title words, and that the threshold value required for retrieval is raised at the same time. raising this value decreases the probability of retrieval, but it is not clear by how much the value is to be raised. for purposes of the test, the threshold value was not raised at all in cases where title words were out of correct sequence, thus retaining maximum probability of retrieval based on the number of matched words alone, regardless of their sequence. results of the test showed that, of the 126 documents in the full sample which were located successfully by manual search in the existing card catalog, only 88 were retrieved by the compression-code method-a recall rate of 70%. considering only the 106 english-language references, 77 were retrieved by the compression-code method-a recall rate of 73%. the premise for the preceding calculation of recall rate should be clearly understood. the test considered real document searches that were concluded successfully in an actual library using a manual catalog; recall is defined here as the proportion of such searches that would be concluded successfully in a hypothetical, computerized library where the only means of searching the catalog would be by ruecking•s method. in a real library with a manual catalog, wanted documents can be located in many ways, not merely through a knowledge of author and title (e.g., through subject entries, series entries, cross references). the test did not disqualify any manual approaches from consideration; it compared the real world with a specific potential alternative. obviously, the use of ruecking's method in combination with other computer programs could result in a recall rate higher than 70% or 73% by the method of calculation employed, and conceivably higher than 100% (because some document searches of manual catalogs that now end in failure might become successful using new search methods). ruecking' s w ord-compression/lipetz 269 table 1 provides detailed information on the discrepancies between user data and catalog data in the test. with respect to the full sample ( 126 documents), there were 49 documents for which mismatches of data were observed. of these, the compression-code method was able to "heal" mismatches in 11 instances to cause retrieval; on the other hand, manual searches had achieved retrieval in all 49 instances. with respect to the english-language sample ( 106 documents), there were 37 documents for which mismatches of data were observed. of these, the compressioncode method was able to "heal" mismatches in 8 instances to cause retrieval; on the other hand, manual searches had achieved retrieval in all 37 instances. contrary to expectations, the compression-code method performed somewhat worse, or at least no better, in "healing" actual mismatches in english references ( 8 out of 37) than it did with foreign-language references ( 3 out of 12). the higher

are lower than totals of figures in columns because some documents had two or more types of mismatch. 270 journal of library automation vol. 2/4 december, 1969 language subset is attributable entirely to the fact that users had complete and correct data more frequently for english references ( 69 out of 106) than they did for foreign-language references (8 out of 20). thus, regardless of original intent, the method words equally well (or equally poorly, depending on one's viewpoint) on foreign-language and english references. if foreign-language references had been systematically ignored in applying the test to catalog searches, some 16% ( 20 out of 126) of the searches would have been excluded, with no real gain in performance. the block of interviews from which the searches used in this test were drawn included 10 unsuccessful document searches in addition to the 126 successful searches. one could speculate on whether the compressioncode method would have been able to "heal" these failures, resulting in a higher performance rating. the indications are, however, that the chances of such healing are close to zero. in a majority of these unsuccessful searches, the available data were incomplete or were not of the type that the method is intended to utilize. in the few remaining cases, it is very likely that the searches were unsuccessful simply because the desired documents were not in the library collection. recall performance as measured by the test could have been improved by modifying ruecking' s rules to some extent. for example, five more titles would have been retrieved had the assigned retrieval value been increased by two units in cases where the first title word matched correctly; this would have increased overall recall performance from 70% to 7 4%. a further increase to 76% would have resulted from matching the user's version of the title with the catalog's subtitle, or with portions of titles which follow a punctuation mark (in addition to matching with the actual title in the catalog). extension of the compression code to include publisher and date as well as author and title would do little or nothing to improve the performance of this method. the test data, although admittedly a small sample, indicate that users who do not have accurate author and title information when they begin a search very rarely have accurate information on any other descriptive data element. it is, of course, a matter for individual judgment as to whether the performance of the compression-code method, as indicated by the test reported here, is sufficiently good to make it attractive for use in some computerized alternative to the manual library catalog. in the authors' opinion, ruecking's method does not in itself supply an adequate solution to the problem of searching a computerized catalog. however, further investigation seems warranted along two lines. first, the method might be modified to give better performance in this application. second, it might be used in combination with some other computer methods to give searching performance approaching that which is attained today by the manual searching of card catalogs.

conceptual design of an automated national library system, by norman r. meise. metuchen, n.j.: scarecrow press, 1969. 234 pp. $5.00. this is a very confusing book. and it is too bad, because this reviewer kept feeling that the author, norman meise, had something to present. the trouble is that he does not communicate. this, i think, is the result of two things. first, the book reflects the naivete of engineers when they come to deal with what are basically social systems like libraries. this does not mean it can't be done, but such a task needs clarity and purpose, which this book does not have. the second springs from this failure. the masses of data, assumptions, and commentary in the book are poorly organized and intenelated. it is not enough to write strings of words; those strings must communicate and relate backward and forward in the text. although never explicitly stated, the book evidently grew out of a study performed by the united aircraft corporate systems center in 1965-66 for the development and implementation of a connecticut library research center (see eric document ed 0221512) . the latest reference in the book is 1966. in a field, i.e. library networks, where a fair amount of work and discussion has taken place in the last three years (e.g. the edunet conference in 1966), a book like this quickly loses its impact. the purpose of the book, according to the author, is "to show the feasibility of a system concept rather than provide a detailed engineering design." the system is "an automated national library system" using the state of connecticut as a model. the author then adds (spoiling the whole introduction) : "if these functions (bibliographic searching, acquisition, cataloging, circulation) can be economically automated, the major problems associated with our information explosion will be solved." as anatole france once said: "it is in the ability to deceive oneself that the greatest talent is shown." seeing through ontologies editorial board thoughts seeing through vocabularies kevin ford information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.12367 kevin ford (kevinford@loc.gov) is librarian, linked data specialist in the library of congress’s network development and marc standards office. he works on the library’s bibframe initiative, and similar projects, such as mads/rdf, and is a member of the ital editorial board. the ideas and opinions expressed here are those of the author and do not necessarily reflect those of his employer. “ontologies” are popular in library land. “vocabularies” are popular too, but it seems that the library profession prefers “ontologies” over “vocabularies” when it comes to defining classes and properties that attempt to encapsulate some realm of knowledge. bibframe, mads/rdf, bibo, premis, and frbr are well-known “ontologies” in use in the library community.1 they were defined either by librarians or to be used mainly in the library space, or both. skos, foaf, dublin core, and schema are well known “vocabularies.”2 they are used widely by libraries though none were created by librarians or specifically for library use. in all cases, those ontologies and vocabularies were created for the very purpose of publication for broader use, which is one of the primary objectives behind creating one: to define a common set of metadata elements to facilitate the description and sharing of data within a group or groups of users. ontologies and vocabularies are common when working with rdf (resource description framework), a very simple data model in which information is expressed as a series of triple statements, each consisting of three parts: a subject, a predicate, and an object. the types of ontologies and vocabularies referred to here are in fact defined using rdf—thing a is a class and thing z is a property. those using any given ontology or vocabulary employ the defined classes and properties to further describe their things, for a lack of a better word. it is useful to provide an example. the first block of triples below represents class and property definitions in rdf schema (rdfs), which provides some very basic means to define classes and properties and some relationships between them, such as the domains and ranges for properties. the second block is instance data. ontovoc:book rdf:type rdfs:class ontovoc:authoredby rdf:type rdf:property ontovoc:authorof rdf:type rdf:property ex:12345 rdf:type ontovoc:book ex:12345 ontovoc:authoredby ex:abcde ontovoc:book is defined as a class and ontovoc:authoredby is defined as a property. using those declarations, it is possible to then assert that ex:12345, which is an identifier, is of type ontovoc:book and was authored by ex:abcde, an identifier for the author. is the first block— the definitions—an “ontology” or a “vocabulary?” putting aside the question for now, air quotes— in this case literal quotes—have been employed around “ontologies” and “vocabularies” to suggest that these are more terms of art than technical distinctions, though it must also be acknowledged that there is a technical distinction to be made. mailto:kevinford@loc.gov information technology and libraries june 2020 seeing through vocabularies | ford 2 ontologies in the rdf space frequently, if not always, use classes and properties from the web ontology language (known as owl) to define a specific realm’s classes and properties and how they relate to each other within that realm of knowledge. this is because owl is a more expressive definition language than basic rdfs. using owl, and considering the example above, ontovoc:authoredby could be defined as an inverse of ontovoc:authorof. ontovoc:authoredby owl:inverseof ontovoc:authorof in this way, and given the little instance data above (the two triples that begin ex:12345), it is then possible to infer the following bit of knowledge: ex:abcde ontovoc:authorof ex:12345 now that the owl:inverseof triple/declaration has been added to the definitions, it’s worth reasking: do the definitions represent an “ontology” or a “vocabulary?” a purist might answer “not an ontology,” but only because those statements have not been combined in a document, which itself has been given a uri and declared to be an owl:ontology. that’s the actual owl class that says, “this is an owl ontology.” but let’s say those statements had been added to a document published at a uri and declared to be an owl:ontology. is it an ontology now? perhaps in a strict sense the answer is “yes.” but in a practical sense few would view those four declarations, wrapped neatly in a document that has been given a uri and called an ontology, as an “ontology.” it doesn’t quite rise to the occasion—“ontologies” almost always have a broader scope and employ more formal semantics—making its use a term of art, often, rather than a real technical distinction. yet, based on the same narrow definition (a published document declaring itself to be an owl:ontology) combined with a far more extensive set of class and property definitions with defined relationships between them, it is possible to describe foaf as an ontology.3 but it is widely known as, and understood as, a “vocabulary.” (there is also an experimental version of schema as owl.4) and that gets to the crux of the issue in many ways. putting aside the technical distinction that can be argued to identify something as an “ontology” versus a “vocabulary,” there are non-technical semantics at work here—what was earlier described as a “term of art”—about when, how, and why something is deemed an “ontology” versus a “vocabulary.” the library community appears to think of their creations as “ontologies” and not “vocabularies,” even when the documentation tends to avoid the word “ontology.” for example, the opening sentence of the bibframe and mads/rdf documentation very clearly introduces each as a “vocabulary,” as does frbr in rdf.5 on the surface they may be presented as “vocabularies,” which they are of course, but despite this prominent self-declaration they are not seen in the same light as foaf or schema but instead as something more exacting, which they also are. it is worth contemplating why they are viewed principally as “ontologies” and to examine whether this has been beneficial. perhaps the ideas behind designating something a “vocabulary” are, in fact, more in line with the way libraries operate, whereas “ontologies” represent an ideal (and who doesn’t set their sights on the ideal?), striving toward which only exposes shortcomings and sows confusion. the answer to “why” is historical and probably derives from a combination of lofty thinking, traditional standards practices, and good ol’ misunderstanding. traditional standards practices favor more formal approaches. libraries’ decades-long experience with xml and xml schema information technology and libraries june 2020 seeing through vocabularies | ford 3 contributed significantly to this mindset. xml schema provides a way to describe the precise construction of an xml document and it can then be used to validate the xml document. xml schema defines what elements and attributes are permitted in the xml document and frequently dictates their order. it can further constrain the values of an element or attribute to a select list of options. in many ways, xml schema was the very expression of metadata quality control. librarians swooned. with the right controls and technology in place, it was impossible to produce poor, variable metadata. in the case of semantic modelling, owl is certainly a more formal approach. it’s founded in description logics whose expressions take the form of occult-like mathematics, at least as viewed by a librarian with a humanities background. owl can be used to declare domains and ranges for properties. one can also designate a property as a datatype property, meaning it takes a value such as a string or a date, as its value, or an object property, which means it will reference another rdf resource as its object. but these declarations are actually more about inferencing—deriving information by applying the ontology against some instance data—and not about restrictions, constraints, or validation. to be clear, there are ways to apply restrictions in owl—“wine can be either red or white”—but this is a form of advanced owl modelling that is not well understood and not often implemented, and virtually never in ontologies designed by librarians. conversely, indicating a domain for a property, for example, is easy, relatively straightforward, and seductive because it gives the appearance that the property can only be used with resources of a specific class. consider: the domain of ontovoc:authoredby is ontovoc:book. that does not mean that the ontovoc:authoredby can only be used with a ontovoc:book resource. it means that whatever resource uses ontovoc:authoredby must therefore be a ontovoc:book. defining that domain for that property is not restricting its use only to books; it allows one to derive the additional knowledge that the thing it is used with must be a book even if it doesn’t identify itself as one. this may seem like a subtle distinction and/or it may seem like tortured logic, but if it does it may suggest that one’s point of view, one’s mindset, favors constraints, restrictions, and validations. and that’s ok. that’s library training and conditioning, completely reinforced in our daily work. it’s what has been taught in library schools for decades and practiced by library professionals even longer. names should be entered “last name, first name” and any middle initial, if known, included. the data in this field should only be a three-character language code from this approved list of language codes. these rules and the consistency resulting from these rules are what make library data so often very high quality. google loves marc records from our community for this very reason. wishing to exert strong control at the definition level when creating a model or metadata scheme with an eye to data quality, it is a natural inclination for librarians to gravitate to a more formal means of defining a model, especially one that seems to promise constraints. so, despite these models self-describing at a high-level as vocabularies, the models themselves employ a considerable amount of owl at the technical level, which becomes the focus of any users wishing to implement the model. users comprehend these models as something more than a vocabulary and therefore view the model through this more complex lens. unfortunately, because owl is poorly understood (sometimes by creators and sometimes by users, and sometimes by both), this leads to various problems. on the one hand, creators and users believe there are technical restrictions or constraints where there are, in fact, none. when this happens, the “constraint” is information technology and libraries june 2020 seeing through vocabularies | ford 4 either identified as a problem (“consider removing the range for this property”) or—and this is more damaging—the property (read: model/vocabulary/ontology) is avoided. even when it is recognized that the “constraint” is not a real restriction (just a means to infer knowledge), forging ahead can generate new issues. when faced with a domain and range declaration, for example, forging ahead can result in inaccurate, imprecise, or simply undesirable inferences. most of the currently open “issues” (about 50 at the time of writing) about bibframe follow a basic pattern: 1) there is a declaration about this property or this class that makes it difficult to use because of how it has been defined with owl; 2) we cannot really use it presently because it would cause potential inferencing issues; 3) consider altering the owl definitions.6 pursuing an (owl) ontology, while formal and seemingly comforting because it feels a little like constraining the metadata schema, can result in confusion and a lack of adoption. given that vocabularies and ontologies are developed and published to encourage users to describe their data in a way that fosters wide consumption by others, this is unfortunate to say the least. it is notable that skos, foaf, dublin core, and schema have very different scopes and potentially much wider user bases than the more library-specific ontologies (bibframe, mads/rdf, bibo, etc.). there is something to be learned here: the smaller the domain, the more effective an ontology might be; the larger the universe, a more general approach may be better. it is further true that foaf, dublin core, and schema define specific domains and ranges for many of their properties, but they have strived for clarity and simplicity. the creators of schema, for example, eschewed the formal semantics behind rdfs and owl and redefine domain and range to better match their needs and (perhaps unexpectedly) most users’ automatic understanding.7 what is generally true is that each of the “vocabularies” approached the creation and defining of their models so as to minimize the use of formal semantics, and promoted this as a feature. in this way, they limited or removed altogether the actual or psychological barriers to adoption. their offering was more accessible, less fussy. bearing in mind the differences in scale and scope, they have been rewarded with a wider adopter base and passionate advocates. the decision to create a “vocabulary” or an “ontology” is a technical one and a political one, both of which must be in alignment. it’s a mindset and it is a statement. it is entirely possible to define the model at a technical level using owl, making it by definition an ontology, but to have it be perceived, and used, as a vocabulary because it is flexible and not strictly defined. likewise, it is not enough to call something a vocabulary, but in reality be a model burdened with formal semantics that is then expected to be adopted and used widely. if the objective is to fashion a (pseudo?) restrictive metadata set with rules that inform its use, and which is strongly bonded with a specific community, develop an “ontology,” but recognize that this may result in confusion and lack of uptake. if, however, the desire is to cultivate a metadata element set that is flexible, readily useable, and positioned to grow in the future because it employs fewer rules and formal semantics, create a “vocabulary.” that’s really what is being communicated when we encounter ontologies and vocabularies. interestingly, the political difference between “vocabulary” and “ontology” appears, in fact, to be understood by librarians: library models self-identify as “vocabularies.” but once past those introductory remarks, the truth is exposed quickly in the widespread use of owl, revealing beyond doubt that it is not a flexible, accommodating vocabulary but a strictly defined model. to dispense with the air quotes: as librarians we’re creating ontologies and calling them vocabularies. we really want to be creating vocabularies that are ontologies in name only. information technology and libraries june 2020 seeing through vocabularies | ford 5 endnotes 1 “bibframe ontology,” library of congress,

(musprog) david f. harrison, music director, wsui-ksui, and randolph j. herber, applications programmer, university computer center, the university of iowa, iowa city, iowa a system to compile programs of recorded music for .broadcast by the university of iowa's radio stations. the system also provides a permanent catalog of all recorded music holdings and an accurate inventory control. the program, which operates on an ibm 360/65, is avaaable in fortran iv, cobol and pl/1, with assembly language subroutines and external maintenance programs. the state university of iowa (iowa city) owns and operates two broadcasting stations, wsui, at 9l0 kc, and ksui, at 91.7 mc. wsui was the first educational radio station in operation west of the mississippi, and ranks among the oldest stations iri the country; ksui was among the earliest of the frequency modulation outlets in the area to offer programming in multiplex stereo. in the spring of 1967, when it became necessary to completely reorganize their recorded music libraries, an investigation wali simultaneously underway to determine the feasibility of utilizing automated data processing ( a.d.p.) techniques in the discographic operations of the stations. at the time there were several working bibliographic applications ( 1), ranging from relatively simple record-keeping (where is ... ? ) to more ambitious cross-referencing and indexing operations, one of which uses the kwic (keyword-in-context) computer program to classify musical recordings ( 1). on the basis of the awareness of these applications, and a belief that the intrinsic principles could be utilized and extended to cover somewhat different needs, it was proposed that the facilities of the uni2 journal of library automation vol. 2/1 march, 1969 versity computer center be employed in the selection and updating of recorded music programs. in designing a coded set of instructions to perform these tasks, it was deemed necessary that any attempt at the selection or compilation of a series of music programs should be made in accordance with certain criteria supplied to the system by the user, and that these selection specification parameters should closely parallel those which would be employed were such an extraction from the total libraries to be performed manually. additional requisites were that provision be made for updating and enlarging the master file as new items were acquired, and that the coding of the programmed instn.1ctions should be sufficiently flexible to permit inclusion of supplemental criteria as they became desirable. the above proposal met with a certain degree of opposition, the main bone of contention being that such an application would necessarily "dehumanize" music programming. there have been, and will continue to be, similar objections raised by those who are unaware of the advantages offered by a. d. p. and concomitantly unaware of the mental processes which result in what is commonly referred to as "artistic judgment." it is not the purpose of this article to attempt an exhaustive analysis of such processes, nor to castigate the objectors; it is rather simply to bring forth several basic observations dealing with the problem under discussion. a contemporary composer-theorist interested in the applications of a. d. p. techniques to the process of musical composition has observed that no paradoxical "almighty force" exists in science, which, in actual fact, progresses by discrete steps which are at once limited but unpredictable ( 3, 4). the following list of conclusions, although relating specifically to the problems of machine-"created" music, find no less an application to the current problem: creative human thought is an aggregate of restrictions or choices in all fields of human activity, including the arts. certain aspects of these ·judgments can be mechanized and simulated by certain physical mechanisms currently extant, including the cm;nputer. the rapidity of calculation or decision by computer frees human beings from the long and arduous task of manually selecting, compiling and checking of programmed works. the time thus saved can be better spent on such amenities as scripting, with complete performance information and record data, and the always-too-necessary pronouncing aids. moreover, the computer program can be "exported" to any place similarly equipped to be used by other individuals, or where other programmers are able to alter the algorithm to meet their specific needs. the automated music programmer ( musprog) was interpreted as being a series of steps, the first of which specifies that complete mus~c programs are to be selected in accordance with a table of specifications introduced as data, each card containing inforination pertinent to a discrete program. the second step requires that each and every entry in the catalog be i f automated music programmer/harrison and herber 3 checked for availability by any program in the tables established in the preceding step, this status to be determined on the basis of a satisfactory comparison with the individual criteria supplied on the selection specification card. among these are "tests" (note that a failure to meet the requirements in any step disqualifies the item) to determine when the item was last selected, as well as the number of times selected; a check for allowable time length; a check for duplication of composer and/ or title; a statement that stereo recordings are to be used only for fm; a check for acceptable period, style and type of composition; and the decision to update the master file. in the final operation of the program, each duplicate title of a work selected is also updated, simulating selection to prevent its selection during the next month. if each duplicate were given the date factor of the item actually selected, the latter would tend to appear much more frequently than its companions because the program would continue to select the longest available item, and it is reasonably safe to assume that the selected item is the longest version of the title in question. it was necessary, therefore, to devise a means by which each version of a given work (indicated by both title and composer) be given equal weight for "fair" selection. a unidimensional array called item was constructed with ten positions as follows: item (10)/0', '0', '0', '0', '1', '1', '1', '2', '2', '3'/. the index of the array was then selected by referencing a routine which generates random, positive integers in the range one through ten. the contents of that position in item are added to the date factor of the record selected, and the result placed in the corresponding field of the duplicate title under scrutiny. thus there exists a 40% probability that the duplicate will have the same "weight" as the selected item, a 30% chance that the duplicate will be "pushed back" one month, 20% for two months, and a 10% probability that the date factor of the duplicate title will be increased by three months. 'when all the titles have been thus read or updated, the run concludes. figure 1 is the flowchart that is the basic design of musprog and from which the computer program was coded. the program runs on an ibm 360/65 and is available in fortran iv, cobol, and pl 1 with assembly language subroutines and external maintenance programs. copies of these programs may be obtained from the national auxiliary publications service (naps #00278). the machine readable catalog system currently employed by the university's radio stations is, on the whole, independent of the record's origin or manufacture. (the catalog number could be considered as nothing more than an indication of a discrete shelf space. ) the system was designed to facilitate maximally efficient use of the 80 columns available on a punch card. by utilizing two alaphabetic and two decimal characters ranging from aoo through zz99 provision is made for identification of records and tapes in quantities somewhat in excess of seventy-thousand 4 ] ournal of library automation vol. 2/1 number of p rogram spec .. lfication spaces +1 to snumi snumi -1 to snumi write program determine for which station program is being selected indic ate null selection list iy setting pol nter= ~ o'flfrmine which compo~ents of the allowable characteristics are significant fig. 1. flowchart for musprog. march, 1969 to the paogram pointer set j to pointer in piece cep•j-it--l.--------' i from lag add oh f 10 i\iumifr of plfcfs sflfctfd chain rl f: cf to begi nn i ng of list for ,rogram sui i rac t duration from time remain ing c om,u i f lag fr om du ra l io n copy p i e ce informal i on 1 ~ 1 0 spac f automated music programmer/ harrison and herber 5 ph 1 w ri te prog ram poi nter rewind ~npui and r an oom c hang e in to pr opu l a g f i el o fig. 1 continued. 6 journal of library automation vol. 2/1 march, 1969 individual discs or reels. the total of actual single titles possible to catalog in this manner is at least twice that number. the card catalog is made up along more or less standard, triple-reference lines on the familiar 3x5-inch card. these remain in the master card file, but are actually used only for reference purposes, rather than for actual selection. the "real" master library exists in the form of punched cards (later transferred to magnetic tape). each card image contains the following information, with blank columns separating contiguous fields: columns 1-10 composer, or first ten characters if abbreviation necessary. 12-27 title, abbreviations standardized 29-33 duration of work in seconds. 35-37 period of composition. 39-40 type of composition. 42-45 catalog number. 47-57 physical location of item on cataloged disc or tape. 59-64 "date fields, used for updating and usage factors. 66-69 seasonal key, a blank indicating general usefulness. 71-80 field used by musprog for internal record-keeping. operation selection of music by the system is performed in accordance with a table of program specifications which includes information pertinent to the length of the desired program and maximum permissible length of any single work within it, the type of music desired, and additional information, such as date, time and title of the program to be aired and an indication of the station for which the program is to be selected. all the selections for ksui ( fm) are required to be stereophonic. classification into stereophonic and monophonic groups is a function of the catalog number, aoo through z99 being stereophonic and aaoo through zz99 being monophonic. a program selection card contains the following data: columns 1 2-6 7-11 12 13-27 28-79 station code: w for wsui, blank for ksui duration of program in seconds. maximum duration of each item to be selected ( 0 or blank indicates program may consist of but a single work equivalent in length to program duration. number of types being specified. three three-plus-two character fields to specify period and type (modia equals "twentieth-century, orchestra"). if any field is blank, musprog assumes anything acceptable. title of program to be selected, day and time. automated music programmer/harrison and herber 7 as an example, the following specifications were made for a program called "aubade" which was aired at 10:00 a.m. on tuesday, july 30, by wsui. program duration was to be 3400 seconds (56:40), allowing 3:20 for continuity. maximum length of any single work within the program was to be 900 seconds (15 :00). music could be chosen from the contemporary orchestral repertoire, any instrumental work from the classic period, or any type "3" work, i. e., soloist and piano, or chorus a cappella. figure 2 shows a printout of selections for two programs. music sel ected fo r ws ui even i ng con cert 5:30 pm thu rsday. july 2 5 pr ogram no, 6 9 le ng th 860 0 unuse d time is 1 tota l 2:23:19 rangs trom di v el eg !aco fa41 52/82 prok o~ !

42:58 0:4 3: 0 an additional feature of musprog is provision for a periodic summary of library usage, affording the librarian a concise account of frequently played items, as well as an indication of those works which have been selected infrequently or ignored altogether. this report allows the programmer to assess more accurately the maximum number of times a selection may be programmed before it is declared unacceptable. the system also puts out printed lists of works extracted from the library in accordance with a user-specified table of reference fields: e. g., all symphonies, all works by bach, all works of under ten minutes in length, all christmas music; or conceivably, any symphonies by bach which are 8 journal of library automation vol. 2/1 march, 1969 suitable for christmas and less than ten minutes long. this latter step could also include, with minor alterations in the computer program, provision for performances by one specific ensemble or artist only. an external program allows adding items to the master tape, deleting those no longer needed and correcting any of the various fields within individual records; thus if mis-timings or other inaccuracies are noted, it becomes a relatively simple matter to correct them. discussion it can readily be seen that "the machine" neither possesses nor displays "taste" in any conventional sense of that word, since it can select only those types of music which the programmer has declared acceptable. it does not, indeed cannot, show any predilection toward certain types of music to the detriment or exclusion of others, save those which have been removed from the list of potential selections by the programmer. it performs no independent judgments. without doubt, then, there is no logical basis for t.~e cry of "dehumanization," since the program was originally designed by human minds and is, at each step of the process of selection, governed by the human-designed control parameters and program specifications; therefore it cannot select music willy-nilly, but must be told what to do and how to do it. it also has been found that specifications cannot be "plugged in" at random, for the programs thus selected would prove little more than a conglomerate of sundry works bearing no relation to one another. it is very much a necessity that organization and logic be designed into each program to have any coherent programming result. the machine does not "know" what to do unless told. it should be brought out that because of a built-in logic and the order of titles on the master file the program will tend to select the longest works available to fill the specified program time, making up the difference, if any, with progressively shorter pieces until the time is filled, or until no work of acceptable type and sufficient brevity can be located. since the longer works tend to occur among certain types and/ or styles of music, there may be some tenuous grow1ds for a suspicion of bias. it will be observed that musprog does not include information pertinent to performer, conductor, etc. one of the several reasons for this apparent oversight is that such information would, at the outset, have required the use of one to four additional data cards per title. since this information was not deemed absolutely essential to the immediate functions of the program, it was decided to postpone inclusion of such a refinement to some future date. conclusion musprog has been utilized by the state university of iowa since march, 1968, and has resulted in considerable time-saving. for example, the july, 1968, programming required one hundred and two programs automated music programmer/harrison and herber 9 varying in length from thirty minutes to somewhat over four hours, and consisting of a variety of musical styles and representing a diversity of programming difficult to achieve efficiently by ordinary means. in three minutes and twelve seconds, musprog selected the programs, updated the catalog, checked for duplication of selections, timed each program, and printed out the resultant copy properly headed. at an approximate cost of $250.00 per hour, this comes to less than fifteen dollars per month to perform tasks which might normally require two persons, at perhaps two or three dollars per hour, to work an entire week or more. it is doubtful that even then each catalog entry could be examined and an accurate record of usage be kept. acknowledgments a staff research grant from the graduate college, university of iowa, partially supported development and operation of this system. dean duane c. spriestersbach of the graduate college, professor gerard p. weeg, chairman of the department of computer science, and program supervisor robert e. irwin gave generous support and encouragement to the development of musprog. references 1.

(full disclosure: at university of queensland we are conducting a pilot project with publons, to integrate the peerreview activities of our academics into our institutional repository.) in addition to new approaches to peer review, such as publons and academic karma, there are quite a few recent examples of innovations in various aspects of scholarly communication that are worth keeping an eye on. these include new collaborative authoring tools such as overleaf, impact-measurement tools such as impactstory, and personal digital library platforms such as readcube. on a broader scale, initiatives such as peerj are building open access publishing platforms intended to dramatically improve the efficiency of and drive down the overall costs of scholarly publishing. february marked the 14th anniversary of a key trigger event in the open access movement—the launch of the budapest open access initiative in 2002. bob gerrity (r.gerrity@uq.edu.au), a member of lita and the editor of

editor’s comments | gerrity doi: 10.6017/ital.v35i2.9462 2 much has happened in the 14 years since the budapest initiative, on various fronts: o policy—introduction and widespread adoption of funder and institutional oa mandates; o technology--development and widespread adoption of institutional repositories, recent development of mechanisms to facilitate the discovery of oa publications (e.g., share on the library side and chorus on the publisher side); o publishing—establishment of new oa megajournals (e.g., plos, biomed central), embrace of hybrid oa models by mainstream commercial publishers. yet despite all the hype, acrimony, and activity triggered by the oa movement, a recent analysis in chronical of higher education suggests the growth of oa has been slow and incremental: the percentage of research articles published annually in fully open-access format has increased at an average rate of of around one percent a year, from 4.8% in 2008 to 12% in 2015. at this rate, the tipping point for oa still seems very far away. lots of energy has been and continues to be invested by different stakeholders in different approaches, and the green vs. gold argument still predominates. recent developments suggest momentum is gaining for a more radical shift. in december 2015, the max planck institute, a key player in the launch of oa with the berlin declaration on open access in 2003, hosted the 12th version of its annual oa conference to further the discussion around open access. ironically, unlike previous meetings and seemingly in philosophical conflict with the underpinnings of the oa movement, the meeting was by invitation only. given the topic, though, a “proposal to flip subscription journals to open access,” the closed nature of of the meeting is understandable. underpinning the proposal was a 2015 paper from the max planck digital library that suggested that the amount of money currently being spent (largely by libraries) on journal subscriptions should be sufficient to fund research publication costs if applied to a “flipped” journal publishing business model, from subscription-based to gold open access.1 in the netherlands, the university sector has adopted a national approach in negotiating deals with several major publishers (springer, sage, elsevier, and wiley) that allow dutch authors to publish their papers as gold oa, without additional charges (but, depending on the publisher, with limits on total numbers and/or which journals are available within the deals).2 the so-called “dutch deal” by the vsnu (association of universities in the netherlands) and ukb (dutch consortium of university libraries and royal library) takes a national approach to flipping the model, attempting to bundle access rights for dutch readers with apc credits for dutch authors. http://www.arl.org/focus-areas/shared-access-research-ecosystem-share#.v3xhlzn95ty http://www.chorusaccess.org/

https://openaccess.mpg.de/berlin-declaration https://www.mpg.de/9202262/area-wide-transition-open-access information technology and libraries | june 2016 3 the dutch government, which currently holds the eu presidency, is pushing hard for a europewide adoption of this approach. last month, the eu’s competitiveness council agreed that all scientific papers should be freely available by 2020.3 meanwhile, in the us, the “pay it forward” research project at the university of california is examining what the institutional financial impact would be with a flipped model. the study is looking at existing institutional journal expenditures on subscriptions and modeling what a future, apc-based model would look like based on institutional research publication output and estimated average apc charges. who knows when or if a global flip might occur, but it does strike me that the scholarly publishing world is overdue for a major shakeup. from the point of view of a university librarian, focused on keeping journal subscription costs in line (unsuccessfully i might add), i think there is real danger in not considering what a flip to a gold model might look like. the commercial publishers we all complain about are successfully exploiting the gold model as an additional revenue stream which, for the most part, academic libraries have been ignoring, since the individual apcs typically are paid from someone else’s budget. this has allowed the overall envelope of spending on research publication (subscriptions and apcs) to grow significantly. perhaps a more interesting question is what the impact of a flip on libraries would be. if gold oa became the predominant model, we would no longer need all of the complex systems we’ve built to manage subscriptions and user access. to quote homer simpson, “woohoo!” in the “watch this space” arena, ebsco’s recently-launched open-source library services platform (lsp) initiative is beginning to take shape. it now has a name—folio (for future of the libraries is open)—and as marshall breeding put it, the project “injects a new dynamic into the competitive landscape of academic library technology, pitting and open source framework backed by ebsco against a proprietary market dominated by ex libris, now owned by ebsco archrival proquest.”4 publicly listed participants in the project include (in addition to ebsco) ole, index data, bywater, bibliolabs, and sirsi dynix.5 the platform release timetable calls for an initial, “technical preview” release of of the code for the base platform in august 2016, and an anticipated release of the apps needed to operate a library in early 2018.6 1. ralf schimmer, kai karin geschuhn, andreas vogler, disrupting the subscription journals’ business model for the

finding aids to screen readers for visually impaired users. ping fu from central washington university and moira fitzgerald from yale university look at the potential effects of cloud-based next-generation library services platforms on staffing models for systems and technical-services departments. visiting the discovery side of library services, megan johnson from appalachian state university reports on usability testing of appalachian’s “one box” integrated articles and catalog search, using innovative interfaces’ encore discovery service. speaking of usability, i had the chance recently to observe a usability testing session for my library’s website, and was reminded of the importance of designing library websites and delivering web-based library services that will actually be of value to our users, delivered with their context in mind rather than ours. my library, like many others, has a website rich in content and complexity and organized around our structure. to the user i was observing, the complexity and library-centric organization clearly were obstacles to the rich content we offer. an undergraduate art history major, she was primarily interested in library resources and services that were directly connected to her coursework and that were accessible from the university’s learning management system (lms). she valued the convenience of direct access from the lms to library-managed course readings and past exam papers. but, when asked to navigate to the same resources using the library homepage as a starting point, rather than the lms, she quickly became frustrated and confused by the overload of search options with (to her) confusing labels. she was further stymied by our proclivity to make things more complex than they need to be (or should be). a simple example: a common occurrence at the beginning of semester is that students with outstanding library fines/fees are blocked from registering for classes. rather than providing a simple, direct “resolve my library fees” link, with clear instructions on how to fix their problem, as bob gerrity (r.gerrity@uq.edu.au) is university librarian, university of queensland, australia. editor’s comments bob gerrity editor’s comments | gerrity 4 quickly as possible, we instead provide pages of information about how and why the fines/fees were calculated, with no link to a solution to the problem at hand. my takeaways from the session were that (1) our website needs to be radically simplified and (2) we should be focussing on designing and delivering services that can be embedded in the context of the user’s natural workflows, not the library’s. easier said than done, of course. reviewers needed the ital editorial board has room for a couple of additional members, to help us

4; proquest pg. 181 communications using a native xml database for encoded archival description search and retrieval alan cornish the northwest digital archives (nwda) is a national endowment for the humanities-funded effort by fifteen institutions in the pacific northwest to create a finding-aids repository. approximately 2,300 finding aids that follow the encoded archival description (ead) standard are being contributed to a union catalog by academic and archival institutions in idaho, montana, oregon, and washington. this paper provides some information on the ead standard and on search and retrieval issues for ead xml documents. it describes native xml technology and the issues that were considered in the selection of a native xml database, ixiasoft's textml, to support the nwda project. pitti, one of the founders of the ead standard, noted the primary motivation behind the creation of ead: "to provide a tool to help mitigate the fact that the geographic distribution of collections severely limits the ability of researchers, educators, and others to locate and use primary sources."' pitti expanded on this need for ead in a 1999 d-lib article: the logical components of archival description and their relations to one another need to be accurately identified in a machine-readable form to support sophisticated indexing, navigation, and display that provide thorough and accurate access to, and description and control of, archival materials.' in a more recent publication, pitti and duff noted a key advantage offered by ead that relates to the focus of this article, the development of an ead union catalog: ead makes it possible to provide union access to detailed archival descriptions and resources in repositories distributed throughout the world. . . . libraries and archives will be able to easily share information about complementary records and collections, and to "virtually" integrate collections related by provenance, but dispersed geographically or administratively.' in a 2001 american archivist article, roth examined ead history and deployment methods used up to the 2001 time period. importantly, two of the most prominent delivery systems described by roth-dynatext (a server-side solution) and panorama (a client-side solution)-were, by 2003, obsolete products for ead delivery. this is indicative of the rapid pace of change in ead deployment, in part due to the migration from sgml to xml technologies. roth described survey results obtained on ead deployment that underscore the recognized need at that time for a "costeffective server-side xml delivery system." the lack of such a solution motivated institutions to choose html as a delivery method for ead finding aids.4 articles like roth's that describe specific ead search-and-retrieval implementation options are in short supply. one such option, the university of michigan dlxs xpat software, is employed for the search and retrieval of ead and other metadata in the university of illinois at urbanachampaign (uiuc) cultural heritage repository. 5 another option, harvesting ead records into machine-readable cataloging (marc) to establish search and retrieval access in an integrated library system, was described by fleck and seadle in a 2002 coalition for networked information task force briefing. using an xml harvester product created by innovative interfaces, marc records are generated based upon marc encoding analogs included in the ead markup and loaded into an innovative interfaces innopac system. 6 this product has been used to create access to ead finding aids in the catalog for michigan state university's vincent voice library. in a 2001 article, gillilandswetland recommended several desirable features for an ead searchand-retrieval system. she emphasized the challenge of ead search and retrieval by noting the nature of finding aids themselves: archivists have historically been materials-centric rather than user-centric in their descriptive practices, resulting in the finding aid assuming a form quite unlike the concise bibliographic description with name and subject access most users are accustomed to using in other information systems such as library catalogs, abstracts, and indexes.' without describing specific software tools, gilliland-swetland argued for a user-centric approach to the search and retrieval of finding aids by examining the needs of specific user communities such as genealogists, k-12 teachers, and historians. 8 several initiatives similar to the nwda effort are described in the professional literature. the online archive of california (oac), which was founded in the mid-1990s, is a consortium of california specialcollections repositories. a number of key consortium functions are centralized, including "monitoring to ensure consistency of ead encoding across all oac finding aids" according to agreed-upon best practices, a critical need in the creation of a union catalog.9 brown and schottlaender also describe the integration of the oac into the california digital library, which enables linkages between ead alan cornish (cornish@wsu.edu) is systems librarian,

docum ent s into open archives initiative (oai) services in order to enh ance resourc e discovery. a 2002 paper written by prom and habin g, both of whom work with th e uiuc cultural herit age repository, explored th e possibility of mapping ead to oai, the latt er of w hich is based up on th e fifteeneleme nt dublin cor e metadata set (unqualified) . while no ting, "w e do n ot propose that th e full capabiliti es of ead finding aids could be subsum ed by oai," prom and habing sug gested that it is possible to map the top-l eve l and co mpon e nt portions of ea d int o oai, res ul tin g in multipl e oai records from a singl e ead finding aid. in thi s scenario, a sin gle oai record is created from th e collectionlevel information and multipl e records from component-level information in an ead docum en t.11 evaluation of ead search and retrieval products in order to iden tify a software solution for supporting a union catalog of ead findin g aids, the con so rtium conducted a product evaluation. the strengths and weakn esses of the native xml technology em ployed by the consortiu m can be best understood by lookin g at alternative xml product s and product categor ies . table 1 shows the products con sidere d during an evaluati on period th at consisted of both product research and actual trials. in approaching the eva luation, the consortium and its union -catalog host institut ion , the washin gton stat e university libraries, had seve ral specific need s in mind. first, the licensing an d support costs for the product needed to fit w ithin the consortium's budget. second , th e sea rch-andretrieval softw are had to sup port several basic fun ctions: keywo rd searching across all union-cat alog finding aids; specific field searching based upon elements or attribut es in the ead docum ent ; an abilit y to customize the look and feel of the interface and search-results screens; and the ability to display search term(s) in the conte xt of the finding aid . as not ed in the tabl e, three of the ev aluated products are n ativ e xml databases. cyrenne provid es a definition of native xml as a database with the se features: • the xml document is stored intact: "t he xml d ocum ent is preserv ed as a separat e, unique entity in its entirety ." • "schema independenc e," that is, "a ny we ll-formed xml document can be stored and queried." • the qu ery language is xmlbased: "na ti ve xml d ata base vendors typically u se a quer y langua ge d es igned sp eci fically for xml" as opposed to sql.12 of the thr ee native xml products, only the licensi ng costs of ixiasoft's textml and the open-sourc e xindice so ftware fell within the available projec t fundin g. both pack ages were extensively tested, with text ml proving superio r at handlin g th e large (sometimes in the mb-size range) and structurall y complex ead documents crea ted by consortium memb ers. one key strength of textml that m et an nwda consortium-need involved field sea rching. in textml, it is possibl e to m ap a search field to one or m ore xpath s ta tements , enabling th e crea tion of sea rch fields b ase d upon the precise us e of an element or attribute in ead d ocuments. the importanc e of this capability is show n with th e ead <unittitl e> element, which can appear at the collection lev el and at the sub or dinate component level in a docu men t. with textml, usin g its limited xpath support, it is p ossib le to refer ence a specific, contextual use of <unittitle >. in addition to the native xml sol utions , seve ral oth er product 182 information technology and libraries i december 2004 types were considered. an xml qu ery engine, verity ultra seek, was te sted and produced good results whe n u sed for the search and retrieval of consortium docum en ts. 13 ultraseek can be used to search discrete xml files , supports th e creation of custom int erfaces for th e searc hand-r etrie va l sys tem, and ha s strong documentation . pro bably th e most obvious limit a tion in thi s xml qu eryengin e product conc erned the crea tion of search fields. to contras t u ltr asee k with a native xml solution : ultras eek 5 .0 (used du r ing the product trial) lacked xpath support. inste ad, it requir ed a uniqu e eleme ntattr ibute combin ation for the crea tion of a databa se sea rch field . returning to th e <unittitl e> exa mple , cont extual u ses of <unittitl e> could n ot be indexed with o ut recoding consortium docum ent s to create a unique eleme nt-attribut e combination on which to ind ex. an xml-enabled databa se, dlxs xpat, has b een successfully used in se veral ead projects, including oac. one d isadv antage of this product is th at it re quir es a unix operating sys tem for th e se rver. a dditionall y, xpat, as a supporting toolse t for di gital-library collection building, provid es functionalit y that duplicates other media tool s at the ho st institution (specifically, oclc/ dim ema contentdm). the use of a relational dat abase management system (rdbms) to es tablish sea rch and retri eva l for ead xml d ocume nts was con sidered as well. th e advantage to thi s approac h is th at it would ena ble the u se of codin g techniques built up through other web-based media d elivery proj ects at the ho st institution. the mo st obvio us negati ve issue is th e need to map xml elements or attributes to tables and field s in an rdbms, which , as cyrenne notes, "is often expensiv e and will m ost likely res ult in the loss of some dat a suc h as processing in stru ctions , and comments as well as the noti on of eleme nt and attribut e orderin g." 14 the reproduced with permission of the copyright owner. further reproduction prohibited without permission. table 1. nwda

another approac h considered was the use of an integrated library sys tem product. this was a realistic option for nwda becaus e consortium member institutions had decid ed to include marc encoding catalogs for selected elements in union-catalog findin g ai ds. inn ovative int er faces produces an xml harve ste r that can be u sed to gen erate marc records from ead findin g aids th a t include marc encoding analo gs. for this proj ect, a local ( or self-cont aine d) cat alog could hav e been created and p opulated with marc records containing metadat a for th e ead docum en ts, includin g a url for online access. this approach offers important strengths and weaknesses . on the positiv e side, it is a relati ve ly eas y meth od for enablin g search-and-retrieval access to ead findin g aids. in contrast to the int er face coding requirement s for textml, the xml harvest er provided an almost tu rn key approach to xml search and retrieval. on the negativ e side, tw o factors stood out during th e evaluation . first, it would be difficult to fully custom ize sea rch-andretrieval interfaces as needed for th e proj ec t. second, u sing the xml harv ester, there is no ability to display searc h terms in the context of the findin g aid. search and retrieval is bas ed upon the m etadata extract ed from th e finding aid usin g th e marc analogs. in michigan state's voice librar y impl eme ntation of thi s so lution , th e finding aid is an external resource with no hi ghlighting of search ter ms . strengths and weaknesses of the textml approach each p roject has it s ow n specific n eed s; thu s, th ere is no correct approach to establishing searc h and retrieval for ead xml documents. in taking th e needs and resources of th e nwda conso rtium into account, ixiaso ft's textml, a nati ve xml prod uct, pr ovi ded the best fit and was licens ed for u se. the use of textml enables the creation of customized interfac es for an xml d atabase (or docum en t base, u sing the textml terminol ogy) and pro vides support for ke yword and field sea rching of consortium documents. the qualified xpath support in textml enables search fields to be built up on precis e element or attribute combinations wi thin ead document s. the existence of a major findingaids int erne t site empl oy ing textml was a factor in the proj ect's selection of the sof tware . th e acces s to archive s (a2a) site, access ible from url www .a2a.pro.gov.uk / , provid es an excell ent model for a publicly sea rchabl e finding-aid sit e. th e a2a site supp orts keyw ord searching and sea

would contain a database to store book-use information and some gis maps to represent bookshelves. upon analyzing the data stored in the database, different frequ encies of book use across bookshelf layers are displayed on the maps. the tool would provide a wonderful means of visualization through which analysts can quickly realize the spatial distribution of books used in a library. this article reveals that readers tend to pull books out of the bookshelf layers that are easily reachable by human eyes and hands, and thus opens some issues for librarians to reconsider the management of library

bibliometric analyses to identify target journals vadim nikolaevich gureyev, nikolai alekseevich mazov information technology and libraries | december 2013 66 abstract bibliometric analyses were used to identify journals that are representative of the authors’ research institutes. methods to semiautomatically collect data for an institute’s publications and which journals they cite are described. citation analyses of lists of articles and their citations can help librarians to quickly identify the preferred journals in terms of the number of publications, and the most frequently cited journals. librarians can use these data to generate a list of journals that an institute should subscribe to. background recent developments in information technology have had a significant impact on the research activities of scientific libraries. such tools have provided new insights into the workload and duties of librarians in research libraries. in the present study, we performed bibliometric analyses to determine the information needs of researchers, and to determine whether they are satisfied with the journal subscriptions available at their institutes. such analyses are important because of limited funding for subscriptions, increases in the cost of electronic resources, and the publication of new journals, especially open-access journals. bibliometric analyses are more accessible and less labor-intensive when using specially designed web services and software. several databases of citation data are accessible online. the leading publishers of these databases, including thomson reuters and elsevier, promote their products such as the web of science (wos) and scopus with travelling and online seminars to increase the number of skilled users. of note, the number of articles devoted to bibliometric analysis has increased about 4-fold since 2000 (see figure 1). vadim nikolaevich gureyev (gureyev@vector.nsc.ru) is leading bibliographer, information analysis department, state research center of virology and biotechnology vector, novosibirsk, russia. nikolai alekseevich mazov (mazovna@ipgg.sbras.ru) is head of information and library center, trofimuk institute of petroleum geology and geophysics sb ras, novosibirsk, russia. mailto:mgureyev@vector.nsc.ru mailto:mazovna@ipgg.sbras.ru information technology and libraries | december 2013 67 figure 1. growth of publications devoted to informetric analysis. data were generated from the wos using the following request: «topic=((bibliometric* or informetric* or webometic* or scientometric*) and (stud* or analys*))». bibliometric analysis appears to be the most objective method for use by librarians. it is important to note that bibliometric analysis shows high objectivity, even when compared with peer review.1 citation analysis can be used to select target journals because it accurately reflects the needs of researchers and can reveal current scientific trends. it also allows librarians to evaluate the effectiveness of each journal, the significance of each journal to the institute, and the minimum archival depth.2 citation analysis is particularly useful when generating a list of journals for subscription and to determine whether to subscribe to specific journals.3 in the present study, we performed citation analyses of scientific papers that were published by researchers at src vb “vector” (biology and medicine) and ipgg sb ras (geosciences). we analyzed groups of journals that published articles from these two institutes and compared the characteristics of the cited and citing journals. many journals publish articles covering the fields associated with the two institutes (biology and medicine, and geosciences), and journals in these fields tend to have the highest impact factors of all fields. therefore, the methods applied in this study and the results may be generalized to other research libraries. detection of information requirements of researchers using bibliometric analyses to identify target journals | gureyev and mazov 68 study design sources. we analyzed articles published in journals or books by researchers at src vb “vector” and ipgg, together with the references cited in these articles. we limited the articles to those published in 2006–2010 (ipgg) or 2007–2011 (src vb “vector”). we did not analyze monographs, theses, or conference proceedings (including those that were published in journals), because our aim was to optimize the list of subscribed journals. to collect comprehensive data regarding these publications, we used four overlapping sources. (1) the russian science citation index (sci) was used to retrieve articles based on the profile of each researcher. the “bound and unbound publications in one list” option was switched off. (2) thomson reuters sci expanded was used to examine the profile of each researcher. the “conference proceedings citation index” option was switched off. (3) scopus was used to retrieve the publications for each researcher. (4) each head of department provided us with the articles published by each member of the research group within the last 5 years. along with publications in which the affiliation was clearly stated, we also analyzed articles where the authors’ affiliation was not stated, the authors reported a superior organization such as a governmental ministry, and the authors from either institute attributed the work to another affiliation (if they worked at two or more organizations). the translated and original versions of the same article were treated as a single article, and the english version was used in our analyses. for journals that published the original russian article and an english translation, we analyzed the latter. citations. citations from the published articles were analyzed to identify the most frequently cited journals. we ignored references that lacked sufficient information or references included in footnotes. cited monographs, theses, and conference proceedings (including those that were published in journals) were also ignored. for citations published in russian with an english translation, we analyzed the translated version, even if the authors originally cited the russian version. we preferred to include the translated versions because they are included in wos database and we can treat them automatically. for example, the wos indexes articles from russian geology and geophysics (print issn 1068-7971) but not the russian-language version geologiya i geofizika (print issn 0016-7886). journals that had been renamed were treated as one journal, and the current/most recent name was used in the analysis. however, journals that had split into multiple titles were analyzed separately, and the journal’s name at the time the cited article was published was used in the analysis. for this study, we first retrieved the journal name and the year the cited article was published. we then expanded on this information by recording the journal publisher, journal accessibility (i.e. subscription method, paper or electronic), open/pay-per-view access, embargo status, and journal length. we ignored the accessibility of individual articles that had been deposited in the author’s personal website or in an institutional repository. information technology and libraries | december 2013 69 results and discussion table 1 summarizes the publication

bibliographic databases in the fields of biomedicine (a; 2007–2011) and geoscience (b; 2007–2011). table 1 shows that the two institutes have a stable publication history relative to other russian scientific institutes in terms of publication activity, in publishing approximately 150 articles per year. therefore, our results can be generalized to other institutes in these fields. collecting this information may seem to be a daunting task, especially for librarians who have not conducted such analyses before. we used three databases and contacted the heads of department detection of information requirements of researchers using bibliometric analyses to identify target journals | gureyev and mazov 70 directly. however, our data indicate that it is sufficient to use the free-of-charge russian sci, an extensive index of russian scientific articles that includes almost all of the articles published by russian researchers in russian and international journals. nevertheless, it is essential to review the profile of each author. when searching for articles by affiliation, the number of articles retrieved ranged from 28% to 51%, but the number of publications retrieved tended to decrease over time. this phenomenon may be caused by a deficient system used to identify affiliations because of differences in the spelling of the affiliation name (in our case, more than 70 variants have been used), attribution of the research to a superior organization, and two or more affiliations may have the same name.4 furthermore, recent studies1,5 confirmed that information about authors should be collated by their affiliations, rather than by performing searches in bibliographic databases. it seems paradoxical that the wos and scopus databases index russian articles quicker than the russian sci. by subscribing to the same print and electronic journals, we noted that print editions are published before electronic ones. nevertheless, this seems reasonable based on this 2-year retrospective analysis. therefore, routine analysis of russian articles can be partly automated by efficient searches of the russian sci. table 2 presents the citation details.

2. number of cited articles, cited journals, and mean number of references in article in the biomedical field references from articles not indexed in wos were manually extracted, which takes time and effort. references from articles indexed in the wos, including russian articles translated into english, were analyzed semiautomatically. for this purpose, we used endnote software developed by thomson reuters. endnote web is a free alternative that could also be used for this purpose. the references cited in each article were exported into endnote. next, the references were arranged according to the chosen parameters to simplify our analyses. of note, about 35% of the russian articles indexed in wos accounted for 80% of all the references cited in the articles. two possibly reasons for this are (1) the greater number of articles published in translated and international information technology and libraries | december 2013 71 journals, and (2) russian researchers are adopting the western citing culture.6 this finding suggests that it is possible to avoid labor-intensive routine work and to use automated services developed by thomson reuters to collate and analyze up to 80% of all references. the authors of articles in the geosciences field cited 1000 journals, including 750 in western journals and 250 in russian journals. in terms of biomedical articles, the index included 1339 articles, of which 1168 were in western journals and 171 in russian journals. we analyzed about 8000 references cited by authors from each institute over 5 years. the references were divided into three equal groups. the most frequently cited russian journals and book series are listed in table 3. biological and medical sciences geosciences journals/book series percent of

given. detection of information requirements of researchers using bibliometric analyses to identify target journals | gureyev and mazov 72 table 3 shows that two-thirds of all citations were published in only 9% (16/171) of the cited russian biomedical journals. this statistic is even more pronounced in the field of geosciences, as 6% (16/250) of russian journals published 80% of the cited articles. comparing the data between the two institutes, it is notable that the results are consistent. the only difference evident to us is that the geoscience researchers tended to cite more russian journals, whereas biomedical researchers preferred to cite international literature. the greater concentration of citations to select journals in the geosciences field can be explained by the smaller number of citations. in the biomedical field, we observed a high trend towards abundant citations resulting in a wider distribution of citations in each article; the journals with the highest impact factors in biology and medicine confirmed our observation. figures 2 and 3 show the correlations between citations and publication activity in russian journals. figure 2. correlation between publication activity (red) and citations (blue) in the biomedical field (in %) for the data shown in table 3. timescale: 2007–2011. figure 3. correlation between publication activity (red) and

the same journals, and publication activity is highly correlated with citation activity. this is more apparent in the geosciences field, where russian geology and geophysics is the most frequently cited journal, as it published about two-thirds of all cited articles. this is unsurprising because it is published by our institute and is the main multidisciplinary russian journal in the field of geosciences. the most frequently cited international journals are listed in table 4. biological and medical sciences geosciences journals/book series percent of references total (%) journals/book

density in journals in the geosciences field. notably, two-thirds of all citations were to articles published in just 25 journals. in terms of biomedical journals, twothirds of all citations were to articles published in 100 journals. only 1.3% (15/1 168) of the cited journals contained one-third of the cited articles in the biomedical field. the corresponding value for journals in the geosciences field was 0.9% (7/750). the correlations between citation activity and publication activity are shown in figures 4 and 5. information technology and libraries | december 2013 75 fig. 4.

analyses to identify target journals | gureyev and mazov 76 as illustrated in figures 4 and 5, the distribution of citations to international journals was broader than for russian journals, where there are only 1–4 frequently cited journals. this is probably due to the smaller number of russian journals than international journals. figures 4 and 5 also revealed a difference between the two disciplines, as geoscience researchers published their articles in top cited international journals, whereas biomedical researchers rarely published their research in highly cited journals. this may be due to the greater number of biomedical journals or the lower rate of publication, because relatively few articles were published in the major multidisciplinary journals, such as nature or science, or in specialized journals, such as the journal of virology. conclusion citation analysis enabled rapid identification of the most frequently cited journals that are essential to academic researchers. in the biomedical field, we found that 16 russian and 100 international journals published two-thirds of all cited articles in the last 5 years. in the field of geosciences, we identified 4 russian and 25 international journals that were essential to researchers in this field. interestingly, there were four times as many russian and international journals in the biomedical field than in the geosciences field. the journals that published the researchers’ articles were partially correlated with the cited journals in the geosciences field, but this correlation was less obvious for biomedical journals. it is important to note that all aspects of this study were performed by librarians who used tools that were available in both institutes. we did not require any additional facilities or the assistance of any researchers. we believe our method is one of the most objective and accessible approach for scientific libraries to select target journals. we used our results to optimize subscribed periodical items. in addition to journal acquisition, our methods and results may be applied to other tasks that may be performed by research libraries. for example, it is possible to study the citing and cited halflives of journals, and compare the results with those reported in the journal citation reports. this allows researchers in specific institutes to determine whether they are citing cutting edge or obsolete literature in their studies. the results can also be used to determine whether the subjects of the cited articles are relevant to the institute’s field of research. finally, the results can be used to compare the list of the most frequently cited international journals within a particular field with the list of journals that are most frequently cited by a research institute. perspectives in this study, we revealed some differences in the correlation between citing and cited journals in two distinct fields, namely geosciences and biomedical science. notably, this correlation was greater for journals in the geosciences field. to determine the factors underlying this phenomenon, it will be interesting to extend our study to a greater number of disciplines. it will also be interesting to compare data for cited journals with their usage statistics. information technology and libraries | december 2013 77 references 1. a.f.j. van raan. “the use

global interoperability in cataloging ilana tolkoff libraries began in complete isolation with no uniformity of standards and have grown over time to be ever more interoperable. this paper examines the current steps toward the goal of universal interoperability. these projects aim to reconcile linguistic and organizational obstacles, with a particular focus on subject headings, name authorities, and titles. i n classical and medieval times, library catalogs were completely isolated from each other and idiosyncratic. since then, there has been a trend to move toward greater interoperability. we have not yet attained this international standardization in cataloging, and there are currently many challenges that stand in the way of this goal. this paper will examine the teleological evolution of cataloging and analyze the obstacles that stand in the way of complete interoperability, how they may be overcome, and which may remain. this paper will not provide a comprehensive list of all issues pertaining to interoperability; rather, it will attempt to shed light on those issues most salient to the discussion. unlike the libraries we are familiar with today, medieval libraries worked in near total isolation. most were maintained by monks in monasteries, and any regulations in cataloging practice were established by each religious order. one reason for their lack of regulations was that their collections were small by our standards; a monastic library had at most a few hundred volumes (a couple thousand in some very rare cases). the “armarius,” or librarian, kept more of an inventory than an actual catalog, along with the inventories of all other valuable possessions of the monastery. there were no standard rules for this inventory-keeping, although the armarius usually wrote down the author and title, or incipit if there was no author or title. some of these inventories also contained bibliographic descriptions, which most often described the physical book rather than its contents. the inventories were usually taken according to the shelf organization, which was occasionally based on subject, like most libraries are today. these trends in medieval cataloging varied widely from library to library, and their inventories were entirely different from our modern opacs. the inventory did not provide users access to the materials. instead, the user consulted the armarius, who usually knew the collection by heart. this was a reasonable request given the small size of the collections.1 this type of nonstandardized cataloging remained relatively unchanged until the nineteenth century, when charles c. jewett introduced the idea of a union catalog. jewett also proposed having stereotype plates for each bibliographic record, rather than a book catalog, because this could reduce costs, create uniformity, and organize records alphabetically. this was the precursor to the twentieth-century card catalog. while many of jewett’s ideas were not actually practiced during his lifetime, they laid the foundation for later cataloging practices.2 the twentieth century brought a great revolution in cataloging standards, particularly in the united states. in 1914, the library of congress subject headings (lcsh) were first published and introduced a controlled vocabulary to american cataloging. the 1960s saw a wide array of advancements in standardization. the library of congress (lc) developed marc, which became a national standard in 1973. it also was the time of the creation of anglo-american cataloguing rules (aacr), the paris principles, and international standard bibliographic description (isbd). while many of these standardization projects were uniquely american or british phenomena, they quickly spread to other parts of the world, often in translated versions.3 while the technology did not yet exist in the 1970s to provide widespread local online catalogs, technology did allow for union catalogs containing the records of many libraries in a single database. these union catalogs included the research libraries information network (rlin), the oclc online computer library center (oclc), and the western library network (wln). in the 1980s the local online public access catalog (opac) emerged, and in the 1990s opacs migrated to the web (webpacs).4 currently, most libraries have opacs and are members of oclc, the largest union catalog, used by more than 71,000 libraries in 112 countries and territories.5 now that most of the world’s libraries are on oclc, librarians face the challenge and inconvenience of discrepancies in cataloging practice due to the differing standards of diverse countries, languages, and alphabets. the fields of language engineering and linguistics are working on various language translation and analysis tools. some of these include machine translation; ontology, or the hierarchical organization of concepts; information extraction, which deciphers conceptual information from unorganized information, such as that on the web; text summarization, in which computers create a short summary from a long piece of text; and speech processing, which is the computer analysis of human speech.6 while these are all exciting advances in information technology, as of yet they are not intelligent enough to help us establish cataloging interoperability. it will be interesting to see whether language engineering tools will be capable of helping catalogers in the future, but for now they are ilana tolkoff (ilana.tolkoff@gmail.com) holds a ba in music and italian from vassar college, an ma in musicology from brandeis university, and an mls from the university at buffalo. she is currently seeking employment as a music librarian. the path toward global interoperability in cataloging | tolkoff 31 best at making sense of unstructured information, such as the web. the interoperability of library catalogs, which consist of highly structured information, must be tackled through software that innovative librarians of the future will produce. in an ideal world, oclc would be smoothly interoperable at a global level. a single thesaurus of subject headings would have translations in every language. there would be just one set of authority files. all manifestations of a single work would be grouped under the same title, translatable to all languages. there would be a single bibliographic record for a single work, rather than multiple bibliographic records in different languages for the same work. this single bibliographic record could be translatable into any language, so that when searching in worldcat, one could change the settings to any language to retrieve records that would display in that chosen language. when catalogers contribute to oclc, they would create the records in their respective languages, and once in the database the records would be translatable to any other language. because records would be so fluidly translatable, an opac could be searched in any language. for example, the default settings for the university at buffalo’s opac could be english, but patrons could change those settings to accommodate the great variety of international students doing research. this vision is utopian to say the least, and it is doubtful that we will ever reach this point. but it is valuable to establish an ideal scenario to aim our innovation in the right direction. one major obstacle in the way of global interoperability is the existence of different alphabets and the inherently imperfect nature of transliteration. there are essentially two types of transliteration schemes: those based on phonetic structure and those based on morphemic structure. the danger of phonetic transliteration, which mimics pronunciation, is that semantics often get lost. it fails to differentiate between homographs (words that are spelled and pronounced the same way but have different meanings). complications also arise when there are differences between careful and casual styles of speech. park asserts, “when catalogers transcribe words according to pronunciation, they can create inconsistent and arbitrary records.”7 morphemic transliteration, on the other hand, is based on the meanings of morphemes, and sometimes ends up being very different from the pronunciation in the source language. one advantage to this, however, is that it requires fewer diacritics than phonetic transliteration. park, whose primary focus is on korean–roman transliteration, argues that the mccune reischauer phonetic transliteration that libraries use loses too much of the original meaning. in other alphabets, however, phonetic transliteration may be more beneficial, as in the lc’s recent switch to pinyin transliteration in chinese. the lc found pinyin to be more easily searchable than wade-giles or monosyllabic pinyin, which are both morphemic. however, another problem with transliteration that neither phonetic nor morphemic schemes can solve is word segmentation—how a transliterated word is divided. this becomes problematic when there are no contextual clues, such as in a bibliographic record.8 other obstacles that stand in the way of interoperability are the diverse systems of subject headings, authority headings, and titles found internationally. resource description and access (rda) will not deal with subject headings because it is such a hefty task, so it is unlikely that subject headings will become globally interoperable in the near future.9 fortunately, twenty-four national libraries of english speaking countries use lcsh, and twelve non-english-speaking countries use a translated or modified version of lcsh. this still leaves many more countries that use their own systems of subject headings, which ultimately need to be made interoperable. even within a single language, subject headings can be complicated and inconsistent because they can be expressed as a single noun, compound noun, noun phrase, or inverted phrase; the problem becomes even greater when trying to translate these to other languages. bennett, lavoie, and o’neill note that catalogers often assign different subject headings (and classifications) to different manifestations of the same work.10 that is, the record for the novel gone with the wind might have different subject headings than the record for the movie. this problem could potentially be resolved by the functional requirements for bibliographic records (frbr), which will be discussed below. translation is a difficult task, particularly in the context of strict cataloging rules. it is especially complicated to translate among unrelated languages, where one might be syntactic and the other inflectional. this means that there are discrepancies in the use of prepositions, conjunctions, articles, and inflections. the ability to add or remove terms in translation creates endless variations. a single concept can be expressed in a morpheme, a word, a phrase, or a clause, depending on the language. there also are cultural differences that are reflected in different languages. park gives the example of how angloamerican culture often names buildings and brand names after people, reflecting our culture’s values of individualism, while in korea this phenomenon does not exist at all. on the other hand, korean’s use of formal and informal inflections reflects their collectivist hierarchical culture. another concept that does not cross cultural lines is the korean pumasi system in which family and friends help someone in a time of need with the understanding that the favor will be returned when they need it. this cannot be translated into a single english word, phrase, or subject heading. one way of resolving ambiguity in translations is through modifiers or scope notes, but this is only a partial solution.11 because translation and transliteration are so difficult, 32 information technology and libraries | march 2010 as well as labor-intensive, the current trend is to link already existing systems. multilingual access to subjects (macs) is one such linking project that aims to link subject headings in english, french, and german. it is a joint project under the conference of european national librarians among the swiss national library, the bibliothèque nationale de france (bnf), the british library (bl), and die deutsche bibliothek (ddb). it aims to link the english lcsh, the french répertoire d’autorité matière encyclopédique et alphabétique unifié (rameau), and the german schlagwortnormdatei/ regeln für den schlagwortkatalog (swd/rswk). this requires manually analyzing and matching the concepts in each heading. if there is no conceptual equivalent, then it simply stands alone. macs can link between headings and strings or even create new headings for linking purposes. this is not as fruitful as it sounds, however, as there are fewer correspondences than one might expect. the macs team experimented with finding correspondences by choosing two topics: sports, which was expected to have a particularly high number of correspondences, and theater, which was expected to have a particularly low number of correspondences. of the 278 sports headings, 86 percent matched in all three languages, 8 percent matched in two, and 6 percent was unmatched. of the 261 theater headings, 60 percent matched in three languages, 18 percent matched in two, and 22 percent was unmatched.12 even in the most cross-cultural subject of sports, 14 percent of terms did not correspond fully, making one wonder whether linking will work well enough to prevail. a similar project—the virtual international authority file (viaf)—is being undertaken for authority headings, a joint project of the lc, the bnf, and ddb, and now including several other national libraries. viaf aims to link (not consolidate) existing authority files, and its beta version (available at http://viaf.org) allows one to search by name, preferred name, or title. oclc’s software mines these authority files and the titles associated with them for language, lc control number, lc classification, usage, title, publisher, place of publication, date of publication, material type, and authors. it then derives a new enhanced authority record, which facilitates mapping among authority records in all of viaf’s languages. these derived authority records are stored on oai servers, where they are maintained and can be accessed by users. users can search viaf by a single national library or broaden their possibilities by searching all participating national libraries. as of 2006, between the lc’s and ddb’s authority files, there were 558,618 matches, including 70,797 complex matches (one-to-many), and 487,821 unique matches (one-to-one) out of 4,187,973 lc names and 2,659,276 ddb names. ultimately, viaf could be used for still more languages, including non-roman alphabets.13 recently the national library of israel has joined, and viaf can link to the hebrew alphabet. a similar project to viaf that also aimed to link authority files was linking and exploring authority files (leaf), which was under the auspices of the information society technologies programme of the fifth framework of the european commission. the three-year project began in 2001 with dozens of libraries and organizations (many of which are national libraries), representing eight languages. its website describes the project as follows: information which is retrieved as a result of a query will be stored in a pan-european “central name authority file.” this file will grow with each query and at the same time will reflect what data records are relevant to the leaf users. libraries and archives wanting to improve authority information will thus be able to prioritise their editing work. registered users will be able to post annotations to particular data records in the leaf system, to search for annotations, and to download records in various formats.14 park identifies two main problems with linking authority files. one is that name authorities still contain some language-specific features. the other is that disambiguation can vary among name authority systems (e.g., birth/death dates, corporate qualifiers, and profession/ activity). these are the challenges that projects like leaf and viaf must overcome. while the linking of subject headings and name authorities is still experimental and imperfect, the frbr model for linking titles is much more promising and will be incorporated in the soon-to-be-released rda. according to bennett, lavoie, and o’neill, there are three important benefits to frbr: (1) it allows for different views of a bibliographic database, (2) it creates a hierarchy of bibliographic entities in the catalog such that all versions of the same work fall into a single collapsible entry point, (3) and the confluence of the first two benefits makes the catalog more efficient. in the frbr model, the bibliographic record consists of four entities: (1) the work, (2) the expression, (3) the manifestation, and (4) the item. all manifestations of a single work are grouped together, allowing for a more economical use of information because the title needs to be entered only once.15 that is, a “title authority file” will exist much like a name authority file. this means that all editions in all languages and in all formats would be grouped under the same title. for example, the lord of the rings title would include all novels, films, translations, and editions in one grouping. this would reduce the number of bibliographic records, and as danskin notes, “the idea of creating more records at a time when publishing output threatens to outstrip the cataloguing capacity of national bibliographic agencies is alarming.”16 the frbr model is particularly beneficial for complex canonical works like the bible. there are a small number of complex canonical works, but they take up a the path toward global interoperability in cataloging | tolkoff 33 disproportionate number of holdings in oclc.17 because this only applies to a small number of works, it would not be difficult to implement, and there would be a disproportionate benefit in the long run. there is some uncertainty, however, in what constitutes a complex work and whether certain items should be grouped under the same title.18 for instance, should prokofiev’s romeo and juliet be grouped with shakespeare’s? the advantage of the frbr model for titles over subject headings or name authorities is that no such thing as a title authority file exists (as conceptualized by frbr). we would be able to start from scratch, creating such title authority files at the international level. subject headings and name authorities, on the other hand, already exist in many different forms and languages so that cross-linking projects like viaf might be our only option. it is encouraging to see the strides being made to make subject headings, name authority headings, and titles globally interoperable, but what about other access points within a record’s bibliographic description? these are usually in only one language, or two if cataloged in a bilingual country. should these elements (format, contents, and so on) be cross-linked as well, and is this even possible? what should reasonably be considered an access point? most people search by subject, author, or title, so perhaps it is not worth making other types of access points interoperable for the few occasions when they are useful. yet if 100 percent universal interoperability is our ultimate utopian goal, perhaps we should not settle for anything less than true international access to all fields in a record. because translation and transliteration are such complex undertakings, linking of extant files is the future of the field. there are advantages and disadvantages to this. on the one hand, linking these files is certainly better than having them exist only for their own countries. they are easily executed projects that would not require a total overhaul of the way things currently stand. the disadvantages are not to be ignored, however. the fact that files do not correspond perfectly from language to language means that many files will remain in isolation in the national library that created them. another problem is that cross-linking is potentially more confusing to the user; the search results on http://www.viaf.org are not always simple and straightforward. if cross-linking is where we are headed, then we need to focus on a more user-friendly interface. if the ultimate goal of interoperability is simplification, then we need to actually simplify the way query results are organized rather than make them more confusing. very soon rda will be released and will bring us to a new level of interoperability. aacr2 arrived in 1978, and though it has been revised several times, it is in many ways outdated and mainly applies to books. rda will bring something completely new to the table. it will be flexible enough to be used in other metadata schemes besides marc, and it can even be used by different industries such as publishers, museums, and archives.19 its incorporation of the frbr model is exciting as well. still, there are some practical problems in implementing rda and frbr, one of which is that reeducating librarians about the new rules will be costly and take time. also, frbr in its ideal form would require a major overhaul of the way oclc and integrated library systems currently operate, so it will be interesting to see to what extent rda will actually incorporate frbr and how it will be practically implemented. danskin asks, “will the benefits of international co-operation outweigh the costs of effecting changes? is the usa prepared to change its own practices, if necessary, to conform to european or wider ifla standards?”20 it seems that the united states is in fact ready and willing to adopt frbr, but to what extent is yet to be determined. what i have discussed in this paper are some of the more prominent international standardization projects, although there are countless others, such as eurowordnet, the open language archives community (olac), and international cataloguing code (icc), to name but a few.21 in general, the current major projects consist of linking subject headings, name authority files, and titles in multiple languages. linking may not have the best correspondence rates, we have still not begun to tackle the cross-linking of other bibliographic elements, and at this point search results may be more confusing than helpful. but the existence of these linking projects means we are at least headed in the right direction. the emergent universality of oclc was our most recent step toward interoperability, and it looks as if cross-linking is our next step. only time will tell what steps will follow. references 1. lawrence s. guthrie ii, “an overview of medieval library cataloging,” cataloging & classification quarterly 15, no. 3 (1992): 93–100. 2. lois mai chan and

displaying in-library use data lauren h. mandel geographic information systems: tools for displaying in-library use data | mandel 47 in-library use data is crucial for modern libraries to understand the full spectrum of patron use, including patron self-service activities, circulation, and reference statistics. rather than using tables and charts to display use data, a geographic information system (gis) facilitates a more visually appealing graphical display of the data in the form of a map. giss have been used by library and information science (lis) researchers and practitioners to create maps that display analyses of service area populations and demographics, facilities space management issues, spatial distribution of in-library use of materials, planned branch consolidations, and so on. the “seating sweeps” method allows researchers and librarians to collect in-library use data regarding where patrons are locating themselves within the library and what they are doing at those locations, such as sitting and reading, studying in a group, or socializing. this paper proposes a gis as a tool to visually display in-library use data collected via “seating sweeps” of a library. by using a gis to store, manage, and display the data, researchers and librarians can create visually appealing maps that show areas of heavy use and evidence of the use and value of the library for a community. example maps are included to facilitate the reader’s understanding of the possibilities afforded by using giss in lis research. t he modern public library operates in a context of limited (and often continually reduced) funding where the librarians must justify the continued value of the library to funding and supervisory authorities. this is especially the case as more and more patrons access the library virtually, calling into question the relevance of the physical library. in this context, there is a great need for librarians and researchers to evaluate the use of library facility space to demonstrate that the physical library is still being used for important social and educational functions. despite this need, no model of public library facility evaluation emphasizes the ways patrons use library facilities. the systematic collection of in-library use data must go beyond traditional circulation and reference transactions to include self-service activities, group study and collaboration, socializing, and more. geographic information systems (giss) are beginning to become deployed in library and information science (lis) research as a tool for graphically displaying data. an initial review of the literature has yielded studies where a gis has been used in analyzing service area populations through u.s. census data;1 sitting facility locations;2 managing facilities, including spatial distribution of in-library book use and occupancy of library study space;3 and planning branch consolidations.4 these uses of gis are not mutually exclusive; studies have combined multiple uses of giss.5 also, giss have been proposed as viable tools for producing visual representations of measurements of library facility use.6 these studies show the capabilities of a gis for storing, managing, analyzing, and displaying in-library use data and the value of gisproduced maps for library facility evaluations, in-library use research, and library justification. n research purpose observing and measuring the use of a library facility is a crucial step in the facility evaluation process. the library needs to understand how the facility is currently being used in order to justify the continued financial support necessary to maintain and operate it. understanding how the facility is used can also help librarians identify hightraffic areas of the library that are ideal locations to market library services and materials. this understanding cannot be reached by analyzing circulation and reference transaction data alone; it must include in-library use measures that account for all ways patrons are using the facility. the purpose of this paper is to suggest a method by which to observe and record all uses of a library facility during a sampling period, the so-called “seating sweep” performed by given and leckie, and then to use a gis to store, manage, and display the collected data on a map or series of maps that graphically depict library use.7 n significance of facility evaluation facility evaluation is a topic of vital importance in all fields, but this is especially true of a field such as public librarianship where funding is often a source of concern.8 in times of economic instability, libraries can benefit from the ability to identify uses of existing facilities and employ this information to justify the continued operation of the library facility. also, knowing which areas of the library are more frequently used than others can help lauren h. mandel (lmandel@fsu.edu) is a doctoral candidate at the florida state university college of communication & information, school of library & information studies, and is research coordinator at the information use management & policy institute. 48 information technology and libraries | march 2010 librarians determine where to place displays of library materials and advertisements of library services. for a library to begin to evaluate patron use and how well the facility meets users’ needs, there must be an understanding of what users need from the library facility.9 to determine those needs, it is vital that library staff observe the facility while it is being used. this observation can be applied to the facility evaluation plan to justify the continued operation of the facility to meet the needs of the library service population. understanding how people use the public library facility beyond traditional measures of circulation statistics and reference transactions can lead to new theories of library use, an area of significant research interest for lis. additionally, the importance of this work transcends lis because it applies to other government-funded community service agencies as well. for example, recreation facilities and community centers could also benefit from a customer-use model that incorporates measures of the true use of those facilities. n literature review although much has been written on the use of library facilities, little of the research includes studies of how patrons actually use existing public library facilities and whether facilities are designed to accommodate this use.10 rather, much of the research in public library facility evaluation has focused on collection and equipment space needs,11 despite the user-oriented focus of public library accountability models.12 recent research in library facility design is beginning to reflect this focus,13 but additional study would be useful to the field. use of gis is on the rise in the modern technological world. a gis is a computer-based tool for compiling, storing, analyzing, and displaying data graphically.14 usually this data is geospatial in nature, but a gis also can incorporate descriptive or statistic data to provide a richer picture than figures and tables can. although gis has been around for half a century, it has become increasingly more affordable, allowing libraries and similar institutions to consider using a gis as a measurement and analysis tool. giss have started being used in lis research as a tool for graphically displaying library data. one fruitful area has been the mapping of user demographics for facility planning purposes,15 including studies that mapped library closures.16 mapping also can include in-library use data,17 in which case a gis is used to overlay collected in-library use data on library floor plans. this can offer a richer picture of how a facility is being used than traditional charts and tables can provide. using a gis to display library service area population data adkins and sturges suggest libraries use a gis-based library service area assessment as a method to evaluate their service areas and plan library services to meet the unique demographic demands of their communities.18 they discuss the methods of using gis, including downloading u.s. census tiger (topologically integrated geographic encoding and referencing) files, geocoding library locations, delineating service areas by multiple methods, and analyzing demographics. a key tenet of this approach is the concept that public libraries need to understand the needs of their patrons. this is a prevailing concept in the literature.19 prieser and wang, in reporting a method used to create a facilities master plan for the public library of cincinnati and hamilton county, ohio, offer a convincing argument for combining gis and building performance evaluation (bpe) methods to examine branch facility needs and offer individualized facilities recommendations.20 like other lis researchers,21 preiser and wang suggest a relationship between libraries and retail stores, noting the similar modern trends of destination libraries and destination bookstores. they also acknowledge the difficulty in completing an accurate library performance assessment due to the multitude of activities and functions of a library. their method is a combination of a gis-based service area and population analysis with a bpe that includes staff and user interviews and surveys, direct observation, and photography. the described multimethod approach offers a more complete picture of a library facility’s performance than traditional circulation-based evaluations. further use of giss in library facility planning can be seen from a study comparing proposed branches by demographic data that has been analyzed and presented through a gis. hertel and sprague describe research that used a gis to conduct geospatial analysis of u.s. census data to depict the demographics of populations that would be served by two proposed branch libraries for a public library system in idaho.22 a primary purpose of this research is to demonstrate the possible ways public libraries can use gis to present visual and quantitative demographic analyses of service area populations. hertel and sprague identify that public libraries are challenged to determine which public they are serving and the needs of that population, writing that “libraries are beginning to add customer-based satisfaction as a critical component of resource allocation decisions” and need the help of a gis to provide hard-data evidence in support of staff observations.23 this evidence could take the form of demographic data, as discussed by hertel and sprague, and also could incorporate in-library use data to present a fuller picture of a facility’s use. geographic information systems: tools for displaying in-library use data | mandel 49 using gis to display in-library use data xia conducted several studies in which he collected libraryuse data and mapped that data via a gis. in one study designed to identify the importance of space management in academic libraries, xia suggests applications of giss in library space management, particularly his tool integrating library floor plans with feature data in a gis.24 he explains that a gis can overcome the constraints of drafting and computer automated design tools, such as those in use at chico meriam library at california state university and at the michigan state university main library. for example, giss are not limited to space visualization manipulation, but can incorporate user perceptions, behavior, and daily activities, all of which are important data to library space management considerations and in-library use research. xia also reviews the use of gis tools that incorporate hospital and casino floor plans, noting that library facilities are as equally complex as hospitals and casinos; this is a compelling argument that academic libraries should consider the use of a gis as a space management tool. in another study, xia uses a gis to visualize the spatial distribution of books in the library in an attempt to establish the relationship between the height of bookshelves and the in-library use of books.25 this study seeks to answer the question of how the location of books on shelves of different heights could influence user behavior (i.e., patrons may prefer to browse shelves at eye level rather than the top and bottom shelves). what is of interest here is xia’s use of a gis to spatially represent the collected data. xia remarks that a gis “is suitable for assisting in the research of in-library book use where library floor layouts can be drawn into maps on multipledimensional views.”26 in fact, xia’s graphics depict the use of books by bookshelf height in a visual manner that could not be achieved without the use of a gis. similarly, a gis can be used to spatially represent the collected data in an in-library use study by overlaying the data onto a representation of the library floor plan. in a third project, xia measures study space use in academic libraries as a metric of user satisfaction with library services.27 he says that libraries need to evaluate space needs on case-by-case basis because every library is unique and serves a unique population. therefore, to observe the occupancy of study areas in an academic library, xia drew the library’s study facilities (including furniture) in a gis. he then observed patrons’ use of the facilities and entered the observation data into the gis to overlay on maps of the study areas. there are several advantages of using gis in this way: spatial databases can store continuing data sets, the system is powerful and flexible for manipulating and analyzing the spatial dataset, there are enhanced data visualization capabilities, and maps and data become interactive. conclusions drawn from the literature a gis is a tool gaining momentum in the world of lis research. giss have been used to conduct and display service area population assessments,28 propose facility locations,29 and plan for and measure branch consolidation impacts and benefits.30 giss also have been used to graphically represent in-library use for managing facility space allocation, mapping in-library book use, and visualizing the occupancy of library study space.31 additionally, giss have been used in combination studies that examine library service areas and facility location proposals.32 these uses of giss are only the beginning; a gis can be used to map any type of data a library can collect, including all measures of in-library use. additionally, gis-based data analysis and display complements the focus in library-use research on gathering data to show a richer picture of a facility’s use and the focus in library facility design literature on building libraries on the basis of community needs.33 n in-library use research that would benefit from spatial data displays unobtrusive observational research offers a rich method for identifying and recording the use of a public library facility. a researcher could obtain a copy of a library’s floor plan, predetermine sampling times during which to “sweep” the library, and conduct the sweeps by marking all patrons observed on the floor plan.34 this data then could be entered into a gis database for spatial analysis and display. specific questions that could be addressed via such a method include the following: n what are all the ways in which people are using the library facility? n how many people are using traditional library resources, such as books and computers? n how many people are using the facility for other reasons, such as relaxation, meeting friends, and so on? n do the ways in which patrons use the library vary by location within the facility (e.g., are the people using traditional library resources and the people using the library for other reasons using the same areas of the library or different areas)? n which area(s) of the library facility receive the highest level of use? it is hoped that answers to these questions, in whole or in part, could begin to offer a picture of how a library facility is currently being used by library patrons. to better view this picture, the data recorded from the observational research could be entered into a gis to 50 information technology and libraries | march 2010 overlay onto the library floor plan in a similar manner as xia’s use of a gis to display occupancy of library study space.35 this spatial representation of the data should facilitate greater understanding of the actual use of the library facility. instead of a library presenting tables and graphs of library use, it would be able to produce illustrative maps that would help explain patterns of use to funding and supervising authorities. these maps would not require expensive proprietary gis packages; the examples provided in this paper were created using the free, open-source mapwindow gis package. example using gis to display in-library use data for this paper, i produced example maps on the basis of fictional in-library use data. these maps were created using mapwindow gis software along with microsoft excel, publisher, and paint (see figure 1 for a diagram of this process). mapwindow is an open-source gis package that is easy to learn and use, but its layout and graphic design features are limited compared to the more expensive and sophisticated proprietary gis packages.36 mapwindow files are compatible with the proprietary packages, so they could be imported into other gis packages for finishing. for this paper, however, the goal was to create simple maps that a novice could replicate. therefore publisher and paint were used for finalizing the maps, instead of a sophisticated gis package. it was relatively easy to create the maps. first, i drew a sample floor plan of a fictional library computer lab in excel and imported it into mapwindow as a jpeg file. i then overlaid polygons (shapes that represent area units such as chairs and tables) onto the floor plan and saved two shapefiles, one for tables and one for computers. a shapefile is a basic storage file used in most gis packages. for each of those shapefiles i created an attribute table (basically, a linked spreadsheet) using fictitious data representing use of the tables and computers at 9 and 11 a.m. and 1, 3, 5, and 7 p.m. on a sample day. the field calculator generated a final column summing the total use of each table and computer for the fictitious sample day. i then created maps depicting the use of both tables and computers at each of the sample time periods (see figure 2) and for the total use (see figure 3). benefits of gis-created displays for library managers the maps presented here are not based on actual data, but are meant to demonstrate the capabilities of giss for spatially representing the use of a library facility. this could be done on a grander scale using an entire library floor plan and data collected during a longer sample period (e.g., a full week). these maps can serve several purposes for figure 1. process diagram for creating the sample maps figure 2. example maps depicting use of tables and computers in a fictional library computer lab, by hour geographic information systems: tools for displaying in-library use data | mandel 51 library managers, specifically regarding the marketing of library services and the justification of library funding. mapping data obtained from library “sweeps” can help identify the popularity of different areas of the library at different times of the day, different days of the week, or different times of the year. once the library has identified the most popular areas, this information can be used to market library materials and services. for example, a highly populated area would be an ideal location over which to install ceiling-mounted signs that the library could use for marketing services and programs. or the library could purchase a book display table similar to those used in bookstores and install it in the middle of a frequently populated area. the library could stock the table with seasonally relevant books and other materials (e.g., tax guidebooks in march and april) and track the circulation of these materials to determine the degree to which placement on the display table resulted in increased borrowing of those materials. in addition to helping the library market its materials and services, mapping in-library use can provide visual evidence of the library’s value. public libraries often rely on reference and circulation transaction data, gate counts, and programming attendance statistics to justify their existence. these measures, although valuable and important, do not include many other ways that patrons use libraries, such as sitting and reading, studying, group work, and socializing. during “seating sweeps,” the observers can record any and all uses they observe, including any that may not have been anticipated. all of these uses could then be mapped, providing a richer picture of how a public library is used and stronger justification of the library’s value. these maps may be easier for funding and supervising authorities to understand than textual explanations or graphs and charts of statistical analyses. n conclusion from a review of the literature, it is clear that giss are increasingly being used in lis research as data-analysis and display tools. giss are being used to analyze patron and materials data as well as studies combining combined multiple uses of giss. patron analysis has included service-area-population analysis and branch-consolidation planning. analysis of library materials has been used for space management, visualizing the spatial distribution of in-library book use, and visual representation of facility-use measurements. this paper has proposed collecting in-library use data according to given and leckie’s “seating sweeps” method and visually displaying that data via a gis. examples of such visual displays were provided to facilitate the reader’s understanding of the possibilities afforded by using a gis in lis research, as well as the scalable nature of the method. librarians and library staff can produce maps similar to the examples in this paper with minimal gis training and background. the literature review and example figures offered in this paper show the capabilities of giss for analyzing and graphically presenting library-use data. giss are tools that can facilitate library facility evaluations, in-library use research, and library valuation and justification. references 1. denice adkins and denyse k. sturges, “library service planning with gis and census data,” public libraries 43, no. 3 (2004): 165–70; karen hertel and nancy sprague,

proceeding, i want to state very clearly that—as with anything i write in this space that is not explicitly attributed to someone other than myself—the reflections that follow are my own thoughts and views. they in no way are intended to represent the views either official or personal of lita or ala officials or employees. w hile i am writing these lines just a week or so after the end of the american library association (ala) midwinter meeting, by the time you see them the ala annual conference in chicago will be just days away. i’ve been reflecting (stewing?) for some time now about the question of ala conferences: why do i attend, and what do i get from these gatherings? is the vendor/exhibitor “tail” wagging the ala/attendee “dog”? is attendance responsible in a time of straitened budgets? and, most recently, what is the environmental cost of attendance? for the moment, i’d like to consider only one of these. we all know that flying is, from an environmental perspective, enormously wasteful and destructive. yet, for attendance at ala and most other professional conferences, air travel is the only practical means, unless either one is fortunate enough to live in the area or ala holds the event in a place such as new york, chicago, philadelphia, or washington, each of which can boast credible commuter rail service. sadly, in most other places trains are really not an option; how many of us can imagine being able to take a long-distance amtrak train to an ala conference? so i wondered what it costs the environment for all of us to go to an ala conference. the following admittedly broad-side-of-barn figures for the recently completed midwinter meeting in denver are real eye-openers (you may not like my assumptions, but we have to assume some things, and after all, i’m only trying to get an orderof-magnitude number): a. number of paid attendees at midwinter meeting 2009: 9,8501 b. “fudge” figure for those who didn’t fly (local attendees or those close enough to use other means of transport): 1,000 c. total number of attendees who flew (a-b): 8,850 d. average distance to denver (round trip, in metric tons of co2 produced): .36352 e. total metric tons of co2—the “carbon footprint”— for all attendees who flew to denver (c x d): 3,217 i’m guessing this is a conservative number; still, the total “carbon footprint” of all who flew to the midwinter meeting was more than 3,000 metric tons of co2.3 that seems to me to be a giant’s footprint indeed for what we are told is primarily a “business meeting.” and this, of course, represents only that portion of the footprint that one identifies with air travel . . . enumerating the actual footprint would require taking into account many other sources of waste, with the resulting total being far larger. is it just me, or does this seem to be an extravagance these days? given that the vast majority of our “business meetings” can be transacted through video conference, teleconference, e-mail, or similar technological means, how do we continue to justify the indulgence of attending such conferences as the planet warms to temperature levels not observed in thousands of years? at a minimum, i would suggest that it’s high time we—individually or as a profession—began to think hard about compensating for our excess by purchasing carbon credits. i personally think of them as “bleeding heart environmentalism,” that is, little more than a means for we “haves” to assuage our guilt about our profligate ways. but even offset payments would be better than nothing. the obvious way to handle this would be for ala to add a modest ($5–10) surcharge to the meeting registration fee, with the resulting proceeds dedicated to an approved beneficiary. let’s see . . . my “carbon footprint” for flying to midwinter meeting 2009 is .38 metric tons. i can purchase an “offset” for about $5 and apply it to any of several worthy causes shown on the carbonfootprint.com website. ah, i feel better already . . . . . . or not. n more midwinter meeting fallout one of the more interesting sessions i attended at the midwinter meeting was a sleeper bearing the title “redefining technical services workflows with oclc.” led by karen calhoun, oclc’s vice president of worldcat and metadata services, a panel that included robin fradenburgh of the university of texas and my university of alberta colleagues kathy carter and sharon marshall described several innovative oclc services aimed at “improv[ing] efficiency and enhanc[ing] access to library materials.”4 calhoun’s overview, “reinventing technical services,” nicely summarized many of the issues facing technical services (ts) operations today, marc truitt (marc.truitt@ualberta.ca) is associate director, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 52 information technology and libraries | june 2009 including declining staff counts and the desire by library administrators to reclaim for patron use the space currently occupied by ts operations. she then reviewed recent studies about our patrons’ changing preferences for research tools—i.e., the question that has often been cast as “google versus the catalog.” precisely how workflow and organizational efficiencies (whether or not they come from oclc) in ts can alter our users’ research habits is a bit beyond me, but i’ll leave it to you to decide. the presentations are available to view at http://www.oclc. org/us/en/multimedia/2009/ala_mw_redefining_ technical_services.htm; do listen to the presentations and decide for yourself. in any case, calhoun’s talk, and an earlier comment made by a colleague and long-time friend of mine, got me to thinking again about “the catalog.” my friend, when asked at another program held just before the midwinter meeting, had said that the ts efficiency she would like most to institute would be “to stop cataloguing new (trade) books.” instead, we should put our limited cataloging resources where they might best be used, that is, in making rare and unique local resources discoverable. whoa!, i thought at the time. how might we do this? as calhoun talked about our users’ preference for discovery outside of the catalog, my mind wandered back to my friend’s comment. worldcat local? probably not, since it would still involve “cataloging” books, and doesn’t seem likely to be any more appealing to the google and amazon–focused user than are our opacs already. but what about amazon? i can envision a “catalog” search that begins at amazon’s already metadatarich site, enhanced with links to local holdings of all the things listed there—amazoncat local, if you will. blue-skying a bit more, i can imagine amazon’s business model for offering this kind of service. not only would there be even more eyeballs on its site than there are now, but a library considering such a service might offer in return that some or all of its acquisitions be sourced to amazon. conceivably, amazon could even offer a shelf-ready service, in which it provided the materials already barcoded, marked, and ready to park on our shelves. hmmm . . . open the box, shelve the already-in-the-“catalog” books, and pay the invoice. sounds pretty simple, no? things are rarely that simple, and i know that. there would be complexities aplenty, but who knows? am i serious? i make this proposal because i come from a background that respects and values the work of catalogers and other ts staff. part of me wants the idea to be tried and found wanting, that some of those who argue that library cataloging is “dead” might then come to a different view. but, either way, what we’d need would be a sizable institution willing to try it and see. who wants to be the pilot site? amazoncat local, anyone? references and notes 1. library journal.com, “with economy sputtering, ala midwinter attendance dips sharply,”www.libraryjournal.com/

with their aid, the variety of items can be described so as to facilitate discrimination among them. in the context of substructure searching, the attributes are representations of fragments of chemical structures,10 while in the case of text, they are strings of characters which are variable in length. these strings are long when the characters comprising them represent frequent combinations, and short when the characters are infrequent.11 since the sets of attributes can generate, in an approximate manner, the variety of items encountered in the data base, they are termed variety generato1·s. they are intermediate in number between the primitive set of symbols ( alphanumeric characters in the case of text, atoms and bonds in that of chemical structures) and the actual variety of items in the collection (words or word fragments in text in the first instance, and molecules in the second). the variety-generator approach involves recognition of the fact that the statistical properties of specific data elements within homogeneous data bases are relatively constant, and that the primitive symbols of the data elements themselves usually show hyperbolic distributions. new symbol sets can therefore be defined, consisting of sequences of primitive symbols such that their frequencies of occurrence become comparable. the new symbol sets then constitute the attributes which are employed, singly or in combination, to represent the items within a search file. these symbol sets variety-generator approachjfokker and lynch 107 approximate to the ideal of equifrequency postulated by shannon for optimal efficiency in communication. 12 only an approximation can be obtained, however, since the distributions of the newly defined symbols still cover a relatively wide range, and since they are seldom entirely independent of one another in statistical terms, and may often be strongly associated. the variety-generator concept is not entirely novel. indeed, it was anticipated most closely in precisely the present context by merrill and by cutter with a view to subdividing a library's holdings into equal groups of items.13 • 14 however, the greater flexibility of computer techniques would appear to make its use today even more attractive. this paper thus describes a study of a large file of authors' names with a view to identifying attributes of the names which can be used for efficient reh·ieval purposes. assessment of the effectiveness of the attributes in retrieval is described in part 2 of this series. (t the main terms used here are n-gram, key, and key-set, where an n-gram is a string of n adjacent characters. a key consists of an n-gram, and keys are chosen so that the frequencies of a set of keys (or key-set) are approximately equivalent in a given file. the measures used in assessing frequency distributions are shannon's expressions for the entropy of a sequence of symbols: and relative entropy: i h = i p1log2pi i= 1 h _ hactual rhmaximum hmaxlmum is reached when the probabilities of occurrence of the symbols of the sequence are equal; its value is the binary logarithm of the variety of symbols, since 1 1 h =n(-log2-) =log2n n n the value of the relative entropy is thus a measure of the degree of equifrequency of a set of symbols, and is independent of their variety. characteristics of name file the file studied was a collection of 100,000 personal names taken from ten issues of the inspec data base dating from the period 1969 to 1972. the names are represented in variable-length format, surname followed by a comma, space and initials each followed by a period. for the present purpose, case and diacritic shift symbols were ignored. <~>to appear in the september 1974 issue of the journal of library automation. 108 journal of library automation vol. 7/2 june 1974 subsets of the file were first sorted into sequence on the basis of the full names, and distributions determined both for surnames and initials, and for surnames alone, as shown in table 1 for the subset of 50,000 names. since the great majority of full names occur once only, the relative entropy of this distribution, at 0.975 (computed with respect to the 50,000 names, i.e., hmax= log250,000), is high, while that for surnames alone is lower, at 0.904. an analysis of the ratio of unique surnames to the total number of entries in files of 25,000, 50,000, 75,000 and 100,000 names showed that the proportion of different surnames added to the file as it increases in size is predictable. the relationship between the number of different surnames (d) and the total number of entries ( n) conforms to the expression: d=antl where a = 5.89 and {3 = 0.78. next, the frequencies of characters at different positions in the surnames and of the initials were determined. the most important positions in the surname are the first and last characters, as will be seen shortly. the distributions of these characters and of the first and second initials are shown in table 2. the relative entropy of the first initial is, interestingly, table 1. distribution of full names and surnames alone in a file of 50,000 inspec names. frequency f 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 > 20 full names no. of names with %of names with frequency f frequency f 35,187 70.37 4,768 19.07 1,060 6.36 302 2.42 88 0.88 34 0.41 16 0.22 7 0.11 3 0.05 1 0.03 2 0.05 1 0.03 total number of different full names = 41,469 h = 15.22 hmax = 15.61 ( log250,000) hr = 0.9753 su1·names no. of surnames with frequencyf % of surnames with frequencyf 19,894 39.79 4,258 17.03 1,597 706 395 235 134 104 68 54 36 39 36 28 24 24 15 19 16 9 112 9.58 5.65 3.75 2.82 1.88 1.66 1.22 1.08 0.79 0.94 0.94 0.78 0.72 0.77 0.51 0.68 0.61 0.36 8.44 total number of different surnames = 27,803 h = 14.11 hmax = 15.61 ( log250,000) hr = 0.9042 variety-generator approachjfokker and lynch 109 table 2. distributions of first and last characters of surname and of initials in 50,000 inspec name me. first character last character first second of surname of surname initial initial s 0.113 n 0.164 j 0.100 space 0.371 b 0.083 r 0.102 a 0.083 a 0.066 m 0.080 a 0.084 r 0.081 m 0.045 k 0.076 s 0.082 m 0.064 j 0.043 h 0.056 i 0.074 g 0.058 s 0.035 g 0.055 e 0.068 v 0.051 l 0.033 p 0.053 v 0.067 d 0.050 e 0.033 c 0.052 y 0.043 h 0.050 r 0.031 r 0.047 t 0.042 s 0.047 p 0.031 l 0.047 0 0.041 e 0.043 g . 0.030 d 0.044 l 0.040 p 0.042 c 0.030 t 0.040 h 0.037 w 0.038 w 0.028 w 0.040 k 0.033 k 0.036 v 0.028 a 0.036 d 0.030 l 0.036 h 0.027 f 0.034 g 0.026 c 0.035 d 0.026 n 0.025 z 0.013 t 0.033 i 0.026 v 0.025 m 0.013 b 0.032 f 0.024 e 0,018 u 0.013 n 0.026 n 0.024 j 0.017 f 0.006 f 0.026 k 0.022 0 0.016 c 0.005 i 0.023 b 0.020 z 0.013 w 0.005 y 0.023 t 0.013 i 0.013 p 0.004 0 0.010 y 0.007 y 0.011 x 0.004 space 0.005 0 0.005 u 0.005 b 0.003 z 0.005 z 0.002 q 0.001 j 0.001 u 0.004 u 0.001 x q 0.0002 q 0.0002 q 0.0002 x 0.0001 x 0.0001 h =4.309 h =4.039 h =4.374 h =3.688 hmax = 4. 700 (log,26) hmax = 4. 700 (log,26) hmax = 4.755 (iog.27) hmax = 4, 755 (log,27) hr = 0.917 hr = 0.859 h. =0.920 h. =0.776 the highest of the four; the highest ranking initial is j, which is one of the least frequent characters in english text. thereafter follow the first and last letters of the surname, and the second initial. the low relative entropy of the last is partly accounted for by the fact that a single initial occurred in 37 percent of the entries. distributions were also obtained for the second and subsequent characters of the surname. these, and also the distributions of the first character, are in general agreement with the results of earlier studies by bourne and ford, and by ohlman, and indicate that consonants predominate in the first position, vowels in the second position, while thereafter the distributions become less disparate. 15• 16 however, due to the variable lengths of names, the dominant character at the sixth and subsequent positions of the surname is the space character. key-set generation technique the basic key-set generation technique involves creating fixed-length 110 journal of library automation vol. 7/2 jube 1974 n-grams from some point or points of reference within each record, the strings generated being initially of length greater than those anticipated within the key-set. these strings are sorted into lexicographic order and counted. (the resultant distribution of the fixed-length strings is again hyperbolic.) the frequencies are compared with a predetermined threshold frequency-at the first stage none of the string frequencies should exceed this value. the strings are then shortened by truncation of the right-hand character, and the frequencies of the strings which have become identical through truncation are accumulated. the new n-gram frequencies are compared with the threshold value; any strings which exceed the value are noted. the procedure is repeated until the single characters are reached. two types of analysis are possible, redundant and nonredundant. ·in the latter, any string exceeding the threshold value is removed from the list and not processed further, while in the former they continue to the next processing stage. while redundant analysis is valuable at the exploratory stage, the nonredundant type is preferred for key-set generation. the procedure was first applied to strings of characters starting with the first character of each surname, as illustrated in figure 1. n-gram foreman forema forem fore for fo f frequency 11 13 24 98 143 214 1685 fig. 1. successive right-hand truncations of a surname during key-set generation here the frequency of the surname foreman in a _file of 50,000 names is eleven. when successively shortened, other surnames with the same initial n-gram are included in the count. comparison of the count with a threshold value results in selection of a key. here, if the threshold were 100, the key selected would be for. application of the procedure to the surnames of the 50,000 name file (the name records had a maximum of eighteen characters, left-justified and space-filled if less than this length), with a threshold frequency of 300 (i.e., a probability of 0.006), gave a key-set consisting of eighty-seven keys, including all the alphabetic characters. the key-set is shown, in alphabetic order, together with the probabilities, in table 3. it is clear that the most frequent characters at the beginning of the surname have produced most keys, s and m with eight keys each, b with seven, k with six, and h, g, p, and r each with five keys. whereas the relative entropy of the initial surname letter was 0.917, that of the key-set is 0.977. the probabilities of no less than seventy of the eighty-seven keys now lie between 0.005 and 0.015. the key-set itself consists of the twenty-six alphabetic characters (one of these, x, is not represented in the collection), fiftyvariety-generator approachjfokker and lynch 111 table 3. key-set of 87 keys produced from 50,000 surnames from inspec files. key p1'0bability key probability key probability key probability a .023 ga .009 m .001 ro .016 al .007 go .011 ma .022 s .027 an .006 gr .012 mar .008 sa .016 b .012 gu .007 mc .007 sch .014 ba .013 h ,006 me .010 se .008 bar .006 ha .021 mi .012 sh .016 be .017 he .010 mo .012 si .010 bo .014 ho .012 mu .008 so .007 br .014 hu .007 n .011 st .016 bu .009 i .013 na .008 t .030 c .013 j .010 ni .006 ta .010 ca .011 jo .007 0 .017 u .005 ch .016 k .015 p .011 v .015 co .013 ka .018 pa .014 va .010 d .015 ki .008 pe .011 w .011 da .009 ko .017 po .010 wa .011 de .013 kr .008 pr .006 we .008 do .007 ku .010 q .001 wi .010 e .018 l .013 r .007 x f .025 la .012 ra .011 y .011 fr .008 le .014 re .008 z .013 g .015 li .009 ri .006 h=6.2952 hmax = 6.443 (log,87) h, =0.977 eight digram keys, and the three trigram keys bar, mar, and sch. the predominance of vowels as the second character of keys is noticeable; forty-nine of the sixty-one n-grams have a vowel in the second position. the size of the key-set produced from a given data base can be varied arbitrarily by changing the threshold value. an approximately hyperbolic relation obtains between the value of the threshold and the number of keys selected. as the size of the key-set increases, the length of the longest n-gram in the key-set increases, and the distribution of n-grams shifts toward higher values, as shown in figure 2. stability of the key-sets with increase in file size is clearly an important factor. to determine the extent of this, successive portions of the entire file of 100,000 surnames were subjected to the analysis at a threshold value of 0.005. as illustrated in table 4, the key-sets are remarkably stable in regard to total key-set size, the number of keys of each length, and to the actual keys. table 4. stability of size and composition of keys with increasing file size. number of number of number of number of total size entries in file characters digrams trigrams of key-set 25,000 26 76 10 112 50,000 26 74 9 109 75,000 26 74 10 110 100,000 26 75 10 111 no, of keys common to key-sets 26 73 9 108 112 ]ou1'nal of library automation vol. 7/2 june 1974 400 300 number of n-grams 200 100 1 2 3 4 5 6 7 8 9 length of n-grams key-set size a 184 b 332 c 572 d 1034 threshold probability 0.0025 0.0015 0.0010 0.0007 10 11 12 13 fig. 2. distribution characteristics of n-grams generated from 10,000 surnames from inspec for four different threshold values as the size of the key-set increases, the range of probabilities represented among the keys narrows, and the relative entropy of the distribution increases, becoming eventually asymptotic with the value of one. this i~ illustrated in figure 3, for the surnames in a file of 50,000 entries. beyond a key-set size of about 100, increases in the relative entropy of the resultant distribution are marginal. furthermore, with increasing key-set size, the va1'iety-gene1'ato1' appmachjfokker and lynch 113 shorter and more frequent surnames begin to appear in their entirety as keys. as an alternative to increasing the variety of the keys, the production of keys from character positions after the first letter of the surname was considered. the problem of variations in name length, as well as the very different distributions of the characters at these positions, were not encouraging, and instead the production of key-sets from the last letter of the sur1 .99 .98 .97 .96 .95 .94 .93 hr .92 .91 .90 .89 .88 .87 .86 0 20 40 60 80 100 total number of keys for the front of surnames fig. 3. increase in relative entropy with increase in key-set size;

55 a recent library journal (lj) story referred to “the palpable hunger public librarians have for change . . . and, perhaps, a silver bullet to ensure their future” in the context of a presentation at the public library association’s 2010 annual conference by staff members of the rangeview (colo.) library district. now, lest there be any doubt on this point, allow me to state clearly from the outset that none of the following ramblings are in any way intended as a specific critique of the measures undertaken by rangeview. far be it from me to second-guess the rangeview staff’s judgment as to how best to serve the community there.1 rather, what got my attention was lj’s reference to a “palpable hunger”for magic ammunition, from whose presumed existence we in libraries seem to draw comfort. in the last quarter century, it seems as though we’ve heard about and tried enough silver bullets to keep our collective six-shooters endlessly blazing away. here are just a few examples that i can recall off the top of my head, and in no particular order: ■■ library cafes and coffee shops. ■■ libraries arranged along the lines of chain bookstores. ■■ general-use computers in libraries (including information/knowledge commons and what-have-you) ■■ computer gaming in libraries. ■■ lending laptops, digital cameras, mp3 players and ipods, e-book readers, and now ipads. ■■ mobile technology (e.g., sites and services aimed at and optimized for iphones, blackberries, etc.) ■■ e-books and e-serials. ■■ chat and instant-message reference. ■■ libraries and social networking (e.g., facebook, twitter, second life, etc.). ■■ “breaking down silos,” and “freeing”/exposing our bibliographic data to the web, and reuse by others outside of the library milieu. ■■ ditching our old and “outmoded” systems, whether the object of our scorn is aacr2, lcsh, lcc, dewey, marc, the ils, etc. ■■ library websites generally. remember how everyone—including us—simply had to have a website in the 1990s? and ever since then, it’s been an endless treadmill race to find the perfect, user-centric library web presence? if sisyphus were to be incarnated today, i have little doubt that he would appear as a library web manager and his boulder would be a library website. ■■ oh, and as long as we’re at it, “user-centricity” generally. the implication, of course, is that before the term came into vogue, libraries and librarians were not focused on users. ■■ “next-gen” catalogs. i’m sure i’m forgetting a whole lot more. anyway, you get the picture. each of these has, at one time or another, been positioned by some advocate as the necessary change—the “silver bullet”—that would save libraries from “irrelevance” (or worse!), if we would but adopt it now, or better yet, yesterday. well, to judge from the generally dismal state of libraries as depicted by some opinionmakers in our profession—or perhaps simply from our collective lack of self-esteem—we either have been misled about the potency of our ammunition, or else we’ve been very poor markspersons. notwithstanding the fact that we seem to have been indiscriminately blasting away with shotguns rather than six-shooters, our shooting has neither reversed the trends of shrinking budgets and declining morale nor staunched the ceaseless dire warnings of some about “irrelevance” resulting from ebbing library use. to stretch the analogy a bit further still, one might even argue that all this shooting has done damage of its own, peppering our most valuable services with countless pellet-sized holes. at the same time, we have in recent years shown ourselves to be remarkably susceptible to the marketingfocused hyperbole of those in and out of librarianship about technological change. each new technology is labeled a “game-changer”; change in general is either— to use the now slightly-dated, oh-so-nineties term—a “paradigm shift” or, more recently, “transformational.” when did we surrender our skepticism and awareness of a longer view? what’s wrong with this picture?2 i’d like to suggest another way of viewing this. a couple of years ago, alan weisman published the world without us, a book that should be required reading for all who are interested in sustainability, our own hubris, and humankind’s place in the world. the book begins with our total, overnight disappearance, and asks (1) what would the earth be like without us? and (2) what evidence of our works would remain, and for how long? the bottom line answers for weisman are (1) in the long run, probably much better off, and (2) not much and not for very long, really. so, applying weisman’s first question to our own, much more modest domain, what might the world be like if tomorrow librarians all disappeared or went on to work doing something else—became consultants, perhaps?— and our physical and virtual collections were padlocked? would everything be okay, because as some believe, marc truitteditorial: no more silver bullets, please marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 56 information technology and libraries | june 2010 think we need to be prepared to turn off the lights, lock the doors, and go elsewhere, because i hope that what we’re doing is about more than just our own job security. and if the far-fetched should actually happen, and we all disappear? i predict that at some future point, someone will reinvent libraries and librarians, just as others have reinvented cataloguing in the guise of metadata. notes and references 1. norman oder, “pla 2010 conference: the anythink revolution is ripe,” library journal, mar. 26, 2010, http://www .libraryjournal.com/article/ca6724258.html (accessed mar. 30, 2010). there, i said it! a fairly innocuous disclaimer added to one of my columns last year seemed to garner more attention (http:// freerangelibrarian.com/2009/06/13/marc-truitts-surprising -ital-editorial/) than did the content of the column itself. will the present disclaimer be the subject of similar speculation? 2. one of my favorite antidotes to such bloated, short-term language is embodied in michael gorman’s “human values in a technological age,” ital 20, no. 1 (mar. 2000): 4–11, http:// www.ala.org/ala/mgrps/divs/lita/ital/2001gorman.cfm (accessed apr 12, 2010)—highly recommended. the following is but one of many calming and eminently sensible observations gorman makes: the key to understanding the past is the knowledge that people then did not live in the past—they lived in the present, just a different present from ours. the present we are living in will be the past sooner than we wish. what we perceive as its uniqueness will come to be seen as just a part of the past as viewed from the point of a future present that will, in turn, see itself as unique. people in history did not wear quaintly oldfashioned clothes—they wore modern clothes. they did not see themselves as comparing unfavorably with the people of the future, they compared themselves and their lives favorably with the people of their past. in the context of our area of interest, it is particularly interesting to note that people in history did not see themselves as technologically primitive. on the contrary, they saw themselves as they were—at the leading edge of technology in a time of unprecedented change. it’s all out there on the web anyway, and google will make it findable? absent a few starry-eyed bibliophiles and newly out-of-work librarians—those who didn’t make the grade as consultants—would anyone mourn our disappearance? would anyone notice? if a tree falls in the woods . . . in short, would it matter? and if so, why and how much? the answer to the preceding two questions, i think, can help to point the way to an approach for understanding and evaluating services and change in libraries that is both more realistic and less draining than our obsessive quest for the “silver bullet.” what exactly is our “valueadd”? what do we provide that is unique and valuable? we can’t hope to compete with barnes and noble, starbucks, or the googleplex; seeking to do so simply diverts resources and energy from providing services and resources that are uniquely ours. instead, new and changed services and approaches should be evaluated in terms of our value-add: if they contribute positively and are within our abilities to do them, great. if they do not contribute positively, then trying to do them is wasteful, a distraction, and ultimately disillusioning to those who place their hopes in such panaceas. some of the “bullets” i listed above may well qualify as contributing to our value-add, and that’s fine. my point isn’t to judge whether they are “bad” or “good.” my argument is about process and how we decide what we should do and not do. understanding what we contribute that is uniquely ours should be the reference standard by which proposed changes are evaluated, not some pie-inthe-sky expectation that pursuit of this or that vogue will magically solve our funding woes, contribute to higher (real or virtual) gate counts, make us more “relevant” to a particular user group, or even raise our flagging selfesteem. in other words, our value-add must stand on its own, regardless of whether it actually solves temporal problems. it is the “why” in “why are we here?” if, at the end of the day, we cannot articulate that which makes us uniquely valuable—or if society as a whole finds that contribution not worth the cost—then i 100 information technology and libraries | june 2009 tutorial andrew darby and ron gilmour adding delicious data to your library website social bookmarking services such as delicious offer a simple way of developing lists of library resources. this paper outlines various methods of incorporating data from a delicious account into a webpage. we begin with a description of delicious linkrolls and tagrolls, the simplest but least flexible method of displaying delicious results. we then describe three more advanced methods of manipulating delicious data using rss, json, and xml. code samples using php and javascript are provided. o ne of the primary components of web 2.0 is social bookmarking. social bookmarking services allow users to store bookmarks on the web where they are available from any computer and to share these bookmarks with other users. even better, these bookmarks can be annotated and tagged to provide multiple points of subject access. social bookmarking services have become popular with librarians as a means of quickly assembling lists of resources. since anything with a url can become a bookmark, such lists can combine diverse resource types such as webpages, scholarly articles, and library catalog records. it is often desirable for the data stored in a social bookmarking account to be displayed in the context of a library webpage. this creates consistent branding and a more professional appearance. delicious (http://delicious .com/), one of the most popular social bookmarking tools, allows users to extract data from their accounts and to display this data on their own websites. delicious offers multiple ways of doing this, from simply embedding html in the target webpage to interacting with the api.1 in this paper we will begin by looking at the simplest methods for users uncomfortable with programming, and then move on to three more advanced methods using rss, json, and xml. our examples use php, a cross-platform scripting language that may be run on either linux/ unix or windows servers. while it is not possible for us to address the many environments (such as cmses) in which websites are constructed, our code should be adaptable to most contexts. this will be especially simple in the many popular php–based cmses such as drupal, joomla, and wordpress. it should be noted that the process of tagging resources in delicious requires little technical expertise, so the task of assembling lists of resources can be accomplished by any librarian. the construction of a website infrastructure (presumably by the library’s webmaster) is a more complex task that may require some programming expertise. linkrolls and tagrolls the simplest way of sharing links is to point users directly to the desired andrew darby (adarby@ithaca.edu) is web services librarian, and ron gilmour (rgilmour@ithaca.edu) is science librarian at ithaca college library, ithaca, new york. figure 1. delicious linkroll page adding delicious data to your library website | darby and gilmour 101 delicious page. to share all the items labeled “biology” for the user account “iclibref,” one could disseminate the url http://delicious.com/iclibref/ biology. the obvious downside is that the user is no longer on your website, and they may be confused by their new location and what they are supposed to do there. linkrolls, a utility available from the delicious site, provides a number of options for generating code to display a set of bookmarked links, including what tags to display, the number, the type of bullet, and the sorting criterion (see figure 1).2 this utility creates simple html code that can be added to a website. a related tool, tagrolls, creates the ubiquitous delicious tag cloud.3 for many librarians, this will be enough. with the embedded linkroll code, and perhaps a bit of css styling, they will be satisfied with the results. however, delicious also offers more advanced methods of interacting with data. for more control over how delicious data appears on a website, the user must interact with delicious through rss, json or xml. rss like most web 2.0 applications, delicious makes its content available as rss feeds. feeds are available at a variety of levels, from the delicious system as a whole down to a particular tag in a particular account. within a library context, the most useful types of feeds will be those that point to lists of resources with a given tag. for example, the request http://feeds.delicious.com/rss/iclibref/biology returns the rss feed for the “biology” tag of the “iclibref” account, with items listed as follows: <item rdf:about=“http://icarus .ithaca.edu/cgi-bin/pwebrecon .cgi?bbid=237870”> <title>darwin’s dangerous idea (evolution 1)</title> <dc:date>2008-0409t18:40:00z</dc:date> <link>http://icarus.ithaca .edu/cgi-bin/pwebrecon. cgi?bbid=237870</link> <dc:creator>iclibref</ dc:creator> <description>this episode interweaves the drama in key moments of darwin&amp;#039;s life with documentary sequences of current research, linking past to present and introducing major concepts of evolutionary theory. 2001</description> <dc:subject>biology</ dc:subject> <taxo:topics> <rdf:bag> <rdf:li rdf:resource=“http:// delicious.com/iclibref/biology”/> </rdf:bag> </taxo:topics> </item> to display delicious rss results on a website, the webmaster must use some rss parsing tool in combination with a script to display the results. the xml_rss package provides an easy way to read rss using php.4 the code for such an operation might look like this: <?php require “xml/rss.php”; /* import rss parser */ $rss = new xml_rss(“http:// del.icio.us/rss/mylibrary/biology”); $rss->parse(); foreach ($rss->getitems() as $item) { echo “<div><a href=’” . $item[‘link’] . “’>” . $item[‘title’] . “</a></div>”; } ?> this code uses xml_rss to parse the rss feed and then prints out a list of linked results. rss is designed primarily as a current awareness tool. consequently, a delicious rss feed only returns the most recent thirty-one items. this makes sense from an rss perspective, but it will not often meet the needs of librarians who are using delicious as a repository of resources. despite this limitation, the delicious rss feed may be useful in cases where currency is relevant, such as lists of recently acquired materials. json a second method to retrieve results from delicious is using javascript object notation or json.5 as with the rss feed method, a request with credentials goes out to the delicious server. the response returns in json format, which can then be processed using javascript. an example request might be http://feeds.delicious . c o m / v 2 / j s o n / i c l i b r e f / b i o l o g y . by navigating to this url, the json response can be observed directly. a json response for a single record (formatted for readability) looks like this: delicious.posts = [ {“u”:“http:\/\/icarus.ithaca .edu\/cgi-bin\/pwebrecon .cgi?bbid=237870”, “d”:“darwin’s dangerous idea (evolution 1)”, “t”:[“biology”], “dt”:“2008-04-09t06:40:00z”, “n”:“this episode interweaves the drama in key moments of darwin’s life with documentary sequences of current research, linking past to present and introducing major concepts of evolutionary theory. 2001”} ]; it is instructive to look at the json feed because it displays the information elements that can be extracted: “u” for the url of the resource, “d” for the title, “t” for a comma-separated list of related tags, “n” for the note field, and “dt” for the timestamp. to display results in a webpage, the feed is requested using javascript: 102 information technology and libraries | june 2009 <script type=“text/javascript” src=“http://feeds.delicious. com/v1/json/iclibref/ films?count=100”></script> then the json objects must be looped through and displayed as desired. alternately, as in the script below, the json objects may be placed into an array for sorting. the following is a simple example of a script that displays all of the available data with each item in its own paragraph. this script also sorts the links alphabetically. <script type=”text/javascript” language=”javascript”> var ourposts = new array(); /* init ourposts array */ /* loop through all items in the json array */ for (var i=0, post; post = delicious.posts[i]; i++) { ourposts[i] = new array(post.d, post.u,post.n,post.t,post.dt); } /* sort the resulting array alphabetically */ ourposts = ourposts.sort(); /* loop through this array, outputting the data in html */ for (var ii=0, item; item = ourposts[ii]; ii++) { document.write(“<p><a href=\”” + ourposts[ii][1] + “\”>” + ourposts[ii][0] + “</ a>”); if (ourposts[ii][2] != null) { document.write(“<br /><strong>notes:</strong> “ + ourposts[ii][2]); } if (ourposts[ii][3] != null) { document.write(“<br /><strong>tags:</strong> “ + ourposts[ii][3]); } document.write(“<br /><strong>timestamp:</ strong> “ + ourposts[ii][4] + “</ p>”); } </script> while rss returns a maximum of thirty-one entries, json allows a maximum of one hundred. the exact number of items returned may be modified through the count parameter at the end of the url. at the ithaca college library, we chose to use json because at the time, delicious did not offer the convenient tagrolls, and the results returned by rss were displayed in reverse chronological order and truncated at thirty-one items. currently, we have a single php page that can display any delicious result set within our library website template. librarians generate links with parameters that designate a page title, a comma-delimited list of desired tags, and whether or not item descriptions should be displayed. for example, www.ithacalibrary.com/research/delish_feed. php?label=biology%20films&tag=bio logy,biologyi&notes=yes will return a page that looks like figure 2. the advantage of this approach is that librarians can easily generate webpages on the fly and send the url to their faculty members or add it to a subject guide or other webpage. the php script only has to read the “$_get” variables from the url and then query delicious for this content. xml delicious offers an application programming interface (api) that returns xml results from queries passed to delicious through https. for instance, the request https://api.del.icio.us/v1/posts/ recent?&tag=biology returns an xml document listing the fifteen most recent posts tagged as “biology” for a given account. <posts tag=“biology” user=“iclibref”> <post href=“http:// figure 2. biology delicious links displayed on a library website adding delicious data to your library website | darby and gilmour 103 icarus.ithaca.edu/cgi-bin/ pwebrecon.cgi?bbid=237870” description=“darwin’s dangerous idea (evolution 1)” extended=“this episode interweaves the drama in key moments of darwin’s life with documentary sequences of current research, linking past to present and introducing major concepts of evolutionary theory. 2001” hash=“01fc0be 0f90232caebe14157eea47d3a” tag=“biology” time=“2008-0409t18:40:00z”/> <!— etc. —> </posts> unlike either the rss or the json methods, the xml api offers a means of retrieving all of the posts for a given tag by allowing requests such as https://api.del.icio.us/v1/ posts/all?&tag=biology. this type of request is labor intensive for the delicious server, so it is best to cache the results of such a query for future use. this involves the user writing the results of a request to a file on the server and then checking to see if such an archived file exists before issuing another request. a php utility called deliciousposts, which provides caching functionality, is available for free.6 note that the username is not part of the request and must be supplied separately. unlike the public rss or json feeds, using the xml api requires users to log in to their own account. from a script, this can be accomplished using the php curl function: $ch = curl_init(); curl_setopt($ch, curlopt_ url, $queryurl); curl_setopt($ch, curlopt_ userpwd, $username . “:” . $password); curl_setopt($ch, curlopt_ returntransfer, 1); $posts = curl_exec($ch); curl_close($ch); this code logs into a delicious account, passes it a query url, and makes the results of the query available as a string in the variable $posts. the content of $posts can then be processed as desired to create web content. one way of doing this is to use an xslt stylesheet to transform the results into html, which can then be printed to the browser: /* create a new dom document from your stylesheet */ $xsl = new domdocument; $xsl->load(“mystylesheet.xsl”); /* set up the xslt processor */ $xp = new xsltprocessor; $xp->importstylesheet($xsl); /* create another dom document from the contents of the $posts variable */ $doc = new domdocument; $doc->loadxml($posts); /* perform the xslt transformation and output the resulting html */ $html = $xp>transformtoxml($doc); echo $html; conclusion delicious is a great tool for quickly and easily saving bookmarks. it also offers some very simple tools such as linkrolls and tagrolls to add delicious content to a website. but to exert more control over this data, the user must interact with the delicious api or feeds. we have outlined three different ways to accomplish this: rss is a familiar option and a good choice if the data is to be used in a feed reader, or if only the most recent items need be shown. json is perhaps the fastest method, but requires some basic scripting knowledge and can only display one hundred results. the xml option involves more programming but allows an unlimited number of results to be returned. all of these methods facilitate the use of delicious data within an existing website. references 1. delicious, tools, http://delicious .com/help/tools (accessed nov. 7, 2008). 2. linkrolls may be found from your delicious account by clicking

university, stanford, california. at the time this article was written, the author was a member of the technical staff, space photography laboratory, california institute of technology, pasadena, california. this paper describes a user-interactive system for the selection and display of pictorial information stored on microfiche cards in a computej'controlled viewer. the system is designed to provide rapid access to photographic and graphical data. it is intended to provide a library of photogmphs of planetary bodies and is currently being used to sto1·e selected martian and lunar photogmphy. introduction information is often most usefully stored in pictorial form. photography, for example, has become an important means of recording data, especially in the sciences. a major reason for this importance is that photographs can be used to record information collected by instruments and not normally observable by the unaided eye. such photographs, especially in large quantities, may present a barrier to their use because of the inconvenience of reproducing and handling them. it is apparent that a system to compactly store and to speed access to these photographs would be very useful. such a system, utilizing a microfiche viewer directly controlled by a user-interactive computer program, has been developed to support a library of photographs taken from space. in the past fifteen years, the national aeronautics and space administration has conducted many missions to photograph planetary bodies. these missions have provided millions of pictures of the earth, moon, and mars. a large number of additional pich1res are expected to be taken in the near future. the space photography laboratory of the california institute of technology is establishing, under nasa auspices, a microfiche library of a selection of these photographs. the library currently contains the photographs of mars taken by the mariner 9 spacecraft as well as lunar photographs taken by the lunar orbiter series. the library is expected to be expanded as time and resources permit. it has been operating, with various versions of the control program, since june 1972. the program is: currently being further developed by mr. david neff and miss laura hormicrofiche libraryjzimmermann 291 ner of the space photography laboratory at the california institute of technology. hardware the photographs are kept on 105-by-148mm microfiche cards, sixty frames to a card. this format provides the least reduction of any standard microfiche format and was used to retain the highest possible resolution. the cards are displayed by a microfiche viewer (image systems, culver city, california) which can store up to about 700 cards and has the capability of selecting a card and displaying any frame on it within a maximum of about four seconds. (throughout this paper, "viewer" will be used to refer to the microfiche viewing device. ) the viewer can be equipped with a computer interface which allows the picture display to be directly computer controlled. an installation consists of the viewer with interface, any standard input/output ( ijo) terminal, and the control program, running, in this case, on a time-shared computer. the terminal is used for communication with the control program. the user enters all commands by typing on the terminal keyboard. the viewer is designed to be plugged in between the computer and i/0 terminal. the computer transmits all information on the circuit to which normally (without the viewer) only the terminal is attached. this information includes the viewer picture display control codes which are recognized and intercepted by the viewer. all other information is passed on to the terminal. no further special equipment is necessary. the system described has been implemented on a digital equipment corporation system 10 medium-scale computer with a time-sharing operating system. the program is written mainly in fortran with some assembly language subroutines. it runs in 12k words ( 36 bits /word) of core memory. the program will not run without conversion on any computer other than the dec system 10. software the control program is user-interactive, that is, it accepts information and commands from the user. these commands allow him to indicate what he desires and to control the action taken by the program. the program permits the user to indicate what characteristics he wishes the pictures to have, selects the pictures that satisfy his criteria, and then allows him to control the display of the selected pictures and to obtain any additional information he may need to interpret the pictures. to guide the user, instructions for use of the system, as well as other infonnation the user may need, are displayed on the viewer as they are required. all user responses are extensively checked for validity. any uninterpretable response is rejected with a message indicating the source of the trouble, and may be reentered in corrected form. it is always possible to return to a previous state, so it is impossible to make a "catastrophic" error. in designing the 292 journal of librat'y automation vol. 7/4 december 1974 system, particular attention was paid to integrating the viewer and computer to utilize the unique capabilities of each. for example, most instructions are presented on the viewer where they can be shown quickly and can be scanned easily by the user. only short messages need to be sent and received by the i/0 terminal. data base a picture is described by a number of characteristics, called parameters. for every picture stored in the viewer, the value for each of these parameters is stored in a disc file. in this application, parameters are mainly used to describe characteristics that are available without analyzing the picture for content. in science, these are the experimental conditions-such as viewing and lighting conditions for space photography. because space photographs are taken by missions with different objectives and equipment, it was necessary to design a library system to include pictures with widely varying selection characteristics. in order to accommodate sets of pictures with widely differing characteristics, without wasting storage space or requiring the elimination of useful descriptors, the computer storage has been structured to allow pictures to be grouped into picture sets, each of which is described by its own set of parameters. conversely, any group of pictures for which the same selection parameters are used forms a picture set. the characteristics of each such set of pictures are also stored and the program reconfigures itself to these characteristics whenever a new picture set is encountered. such an organization allows the control program to be used on groups of totally different kinds of pictures. opemtion in selecting a picture set the user is guided along a series of decisions presented on the viewer. at each step the control program directs the viewer to display a frame with a set of possible choices. the user enters his response on the i/0 terminal and the control program uses this response to determine which frame the viewer should be commanded to display next. when the user has selected a set, he is shown the available parameters and apppropriate values for these parameters. after he has specified acceptable values for the parameters he is interested in, the computer program compares these values with the known values in its records for the picture set. the pictures selected by the program are then available for display. as will be described, the user may, at any time, select another picture set or change his parameter specifications. he may also indicate which pictures of those selected by the computer during the comparison search he wishes to have remain available after the next comparison search. this allows comparison of pictures in different picture sets. appendix 1 shows an example of a typical search. the action of the control program can be separated into five phases of microfiche library/zimmermann 293 operation, each with a distinct function. the functions of three of these phases involve user interaction. transfer between phases may also be accomplished by user command. a different group of commands is employed for each of the user-interactive phases. in addition, there is a group of commands which may be used any time a user response is requested; they are listed in appendixes 3 and 4. there are no required commands or sequences of commands. the user proceeds from one phase to another as he desires. in each phase allowing user interaction, the user can enter any valid command at any time. figure 1 shows the phases and possible transfers between phases. a more detailed description of what occurs in each phase will be given after the data organization is described. picture set selection parameter specification search optimization comparison search picture display and information access bold lines enclose user-interactive phases. arrows indicate possible directions of control transfer; bold arrows are control transfers made by user commands. fig. 1. phases and control transfers. description of software data base organization as has been stated, the pictures of the library are grouped into picture sets. the data base may contain any number of picture sets. each such set has a picture file associated with it. this picture file is on disc storage and 294 journal of library automation vol. 7/4 december 1974 contains all the known information stored for a set of pictures. each picture in the set has an associated picture record in the file. in addition, the first record in a picture file, known as the format record, contains all the file specific information about that file. whenever a new picture file is called for, the format record for that file is read from disc storage into main memory and kept for reference. figure 2 shows the organizational structure of the data base. picture files (as many as required) format record picture records / ~.___i ~i ......_i ~if }ij fig. 2. picture file organization, picture records consist of a fixedand a variable-length portion. the variable-length portion contains the known values, for the associated picture, of the specification parameters. since the number of parameters, can vary from file to file, the length of this portion varies from file to file. (however, all picture records within a particular file have the same length and form.) the maximum number of parameters for a system is determined by array dimensions set when the program is compiled. currently these dimensions are set for a maximum of fifty parameters for any file in the system. the fixed-length portion contains (generally) the same type of information for all files. it includes the information needed to display a picture and to obtain interpretive information. when, during the comparison search, a picture is selected on the basis of information in the variable data, the fixed-length portion is copied into a table and kept for use during the picture display phase. each selected picture is represented by an entry in this table. the contents of the fixed-length portion are presented in table 1. as an example, the contents of a picture record for the mariner 9 photographs are given in appendix 5. a picture file's format record describes the file by all characteristics that are allowed to vary from file to file. the format records for all picture files have the same form; each is divided into a number of fields supplying information for a particular function. these fields can be separated into two categories: those which describe the picture records and those which apply to the file as a whole. for fields of the first type, each parameter has an enb·y in the field. for example, one such field contains the location, in microfiche librm·y /zimmermann 295 table 1. the fixed-length portion of a picture record field use fiche code file name picture number unit number id number auxiliary codes ( 3 fields) control code output by the control program to the viewer to display the frame associated with this picture record. the file name of the picture file; this and the picture number uniquely identify the picture record and allow it, and specifically the contents of the variable portion, to be refound. a sequence number assigned each picture record in the file in increasing order. the viewer that the picture associated with this picture record is stored in. the identification number referred to by the user. if the picture has been given an id number by which it is commonly known, it will be kept in this field. viewer control codes for frames containing different versions of, or auxiliary data for, the picture. the actual contents of these fields vary with the picture file as determined from the contents of the format record of that file. a picture record, of the value for each of the parameters. another field has a ten-letter description of each parameter. see appendix 2 for a description of the format field. operation of the control progmm the following is a brief technical description of the control program; detailed documentation is available. the control program is modularly constructed. each phase consists of a major subroutine and its subsidiary subroutines. at the completion of a phase, control is transferred to a main program which determines which phase is to be performed next and transfers control to it. the user-interactive (interrogation) subroutines ask for a user response, attempt to interpret the response and perform the desired function, then ask for another response. an important subroutine used by all the interrogation subroutines collects the characters of the user response into groups of similar characters to form alphabetic keywords, numbers, punctuation marks, relational operators, etc. when an interrogation subroutine is ready for a user request, it calls this "scanning" subroutine. the scanning subroutine outputs an asterisk, indicating it is ready, to the user i/0 terminal. the scanning subroutine supplies the groups of characters, along with a description of the group, to the interrogation subroutine. the interrogation subroutine then attempts to interpret the character groups by comparing them with acceptable responses. if the response is not in one of the acceptable forms, an error message is given to the user and he can try again. the error message includes an indication of where the error was found and describes the error. some commands do not need to be interpreted by the interrogation subroutines; the function they request is the same throughout the program. these are called immediate commands and are listed in appendix 3. these 296 journal of library automation vol. 7/4 december 1974 commands are interpreted, and their functions performed, by the scanning subroutine. picture set selection in selecting a picture set the user is asked to make a series of decisions. for each decision, a frame listing the possible choices is displayed on the viewer. all possible decisions form an inverted tree structure (see figure 3). the user may also return to a previous decision point. the tree structure is implemented in a table in computer storage. there is an entry in this table corresponding to each decision point in the

the new decision point is obtained. an entry at the bottom of the· tree identifies the picture file associated with the picture set selected. in general, an entry contains: ( 1) the viewer control code of the frame displaying the choices; ( 2) a pointer to the entry from which this node was reached; ( 3) the number of possible decisions which can be made at this decision point (to check for valid decisions); and ( 4) pointers to the entries for the decision points reached. parameter specification once the user has made a decision selecting a set of pictures, he is presented with a list of the available parameters and acceptable values for them. for each parameter in which the user is interested, he specifies the parameter number and the values or range of values acceptable to him. this information is stored in two tables which are referred to when the comparison search is made. one table, the parameter table, contains an entry for each parameter specified. this table is cleared whenever a new picture set is called for. an entry in the table includes: ( 1) the parameter number; ( 2) a code indicating which of several methods is to be used in processing the parameter; ( 3) a code providing information on how the user-specified values are to be interpreted; and ( 4) a pointer to the location in a second table, the values table, where the first of the specified values is stored. all additional values are placed in the values table following the addressed value. the processing code (number ( 2) above) allows each parameter to be processed by a unique method. a standard method for a given parameter is kept in a field of the format record. the user can also specify a method other than the standard one. if an entry already exists for a just-entered parameter, the old entry is updated rather than a new one created. search optimization this phase determines the most efficient way to conduct the comparison search from among a set of alternatives. whenever possible, the search is restricted to only a part of the picture file. for each picture file there is a number of parameters for which additional information is available. specifically, if a list of pictures ordered by increasing value of a parameter is available, the pictures which have a particular value of that parameter can be found more quickly through this list than by searching through the whole file for that value of the parameter. if the position, in this ordered list, of the picture at the low end of a range of values (of the parameter it is ordered on) can be found easily, the search can be started at this point and need only be continued until the picture at the high end has been reached. note that the picture records for the intervening pictures must nonetheless be compared with the user specifications since the restriction is only made on the basis of one parameter whereas more than one may have been specified. 298 ]oumal of library automation vol. 7/4 december 1974 a binary search is the method used to search the list for the first picture in a range of values. to use this method, of a set of n picture records the n / 2th is chosen and its value of the parameter is compared with the desired one. since the list of records is in order of the value of this parameter, it is clear in which half of the list a picture with the desired value of the· parameter would have to be. this interval can then be divided and the process continued until the remaining interval consists of only one picture. the main picture :file is itself usually arranged in order of at least one parameter. for other parameters, control lists of picture numbers ordered by value of these parameters can be used for binary searches. however, it is not practical to create these lists for all parameters as they require a fair amount of storage. an entry in such a list contains two words, the value of the parameter and the picture number of the corresponding picture. picture number is a sequence number which determines the position of the picture record relative to the beginning of the picture :file. each picture file has a table in its format record containing identifiers for the parameters for which the binary search technique can be used. if more than one of these has been specified (as stored in the parameter table), it must be determined which parameter restricts the search the most. to do this the upper and lower limits of the specified values of each such parameter are found (from the values table), and from this the expected number of picture records to be compared is computed. this number is multiplied by a factor indicating the speed of the type of search to be used relative to the speed of the simplest type of search. the parameter· with the lowest expected elapsed time of search is selected for the search. comparison search for each picture to be compared, the appropriate picture record is found and specified parameter values are compared with those in the picture record. a control list, selected in the search optimization phase, may be used to determine which picture records are to be compared. for each selected picture an entry containing a portion of the picture record is made in a picture table. the picture table has a limited capacity which is set when the program is compiled. for our application there is currently room for up to 100 entries. if the picture table is filled before the search is finished, the search is suspended and can be continued by a command in the display phase. picture display, information access this phase accepts commands to conb·ol display of the selected pictures and provide access to interpretive information. the picture table entries provide the information needed, either directly or by referring back to the picture record. any of the selected pictures can be viewed at any time. in addition, the user can "mark" preferred pictures to differentiate them from the others. these marked pictures are set apart in the sense that microfiche library/zimmermann 299 many. viewing and information access commands refer optionally to only these pictures. the pictures themselves are the primary source of information, but the user will often want information that is not available from the picture in order to interpret the picture. there are commands that request the control program to type out on the i/0 terminal the information in a picture record. these commands optionally refer to the picture currently displayed, the marked pictures, or all the selected pictures. other commands call for the display of data frames associated with a picture. these frames can contain large volumes of data that need not be kept in computer storage. the viewer control codes for these frames are kept in the picture table. the keyword commands to display data frames can vary from file to file. the valid commands for a file are kept in the file's format record. there are other commands to transfer control to other phases and to keep desired pictures available for display with those selected by the next comparison search. there is also a provision for adding file specific commands to perform any other function. the commands and their functions are listed in appendix 3. performance and costs a typical simple search consisting of logging in, picture selection, parameter specification, search, and display might take five to ten minutes and cost one to two dollars for compute time. most of this is time spent by the user in entering commands. command execution is usually almost immediate as it does not involve a major amount of computation. most of the compute time is accumulated during the comparison search phase. to search through the entire mariner 9 picture file of around 7,000 pictures (about 200,000 words) takes about forty seconds elapsed time and costs about two dollars. a more typical search, however, will allow some search optimization and cost about thirty cents with an elapsed time of ten seconds. of course, these figures should only be used as estimates, even for other dec system 10 systems, as elapsed time depends on system load and this, as well as the rates charged, varies considerably. total monthly compute costs for a system depend entirely on use. likewise, storage costs depend on actual storage space used. for the 200,000-word mariner 9 file our cost is about seventy-five dollars per month. only the most-used picture files actually need be kept on disc; the rest can be copied from magnetic tape if they are needed. all files are backed up on magnetic tape in any case. the rates listed in this paper are those charged by our campus time-sharing system. dec system 10 computer time is available from commercial firms at somewhat higher rates. the cost for a microfiche viewer with computer interface (image systems, culver city, california, model 201) is around $7,000. a thirty-characters-per-second i/0 terminal sells for $1,500 and leases for $90 per month. in addition, an installation may require a microfiche camera and 300 ]oumal of library autonwtion vol. 7/4 december 1974 other photographic equipment and supplies. photographic services are also available from the viewer manufacturer. the hardware cost for an independent system implemented on a minicomputer with 12k to 20k of core and five million words of disc memory is estimated at an additional $30,000 (exclusive of development and photographic costs). implementing a library system in implementing a library system to use the hardware and software described in this paper, two major areas of effort are required. first, the pictorial information must be converted to microfiche format; that is, it must be photographed, or possibly rephotographed if already in photographic form. in addition, a computer data base must be created. if information about the photographs is already available in computer-readable form, this involves writing a program to convert the data to the structure required by the control program. if this type of information is not available, the pictures may need to be investigated and the information coded, and presumably punched onto computer cards, for further processing. the major difficulties we encountered were coordinating the photographic and data base generation tasks, achieving the high resolution we required to retain the detail of the original photographs, and in using early versions of the microfiche viewer (which had a tendency to jam cards). conclusion a system for rapid access to pictorial information, the computer accessed microfiche library ( caml), has been described. caml has been designed to integrate, in an easy-to-use system, the storage capacity and capability for fast retrieval of a special microfiche viewer with the manipulating ability and speed of a computer. it is believed that this system will help overcome the barriers to the full utilization of photographs in large quantities, as well as have applications in the retrieval of other types of pictorial information. acknowledgments the work described in this paper was

processing of data within bibliographic text paula goossens: royal library albert i, brussels, belgium. an analysis of the codification practices of bibliographic desc1'iptions reveals a multiplicity of ways to solve the p1'oblem of the special processing of ce1tain characters within a bibliographic element. to obtain a clem· insight i'nto this subfect, a review of the techniques used in different systems is given. the basic principles of each technique are stated, examples am given, and advantages and disadvantages are weighed. simple local applications as well as more ambitious shared cataloging p1'0jects are considered. introduction effective library automation should be based on a one-time manual input of the bibliographic descriptions, with multiple output functions. these objectives may be met by introducing a logical coding technique. the higher the requirements of the output, the more sophisticated the storage coding has to be. in most cases a simple identification of the bibliographic elements is not sufficient. the requirement of a minimum of flexibility in filing and printing operations necessitates the ability to locate certain groups of characters within these elements. it is our aim, in this article, to give a review of the techniques solving this last problem. as an introduction, the basic bibliographic element coding methods are roughly schematized in the first section. according to the precision in the element identification, a distinction is made between two groups, called respectively field level and sub:field level systems. the second section contains discussions on the techniques for special processing of data within bibliographic text. three basic groups are treated: the duplication method, the internal coding techniques, and the automatic handling techniques. the different studies are illustrated with examples of existing systems. for the field level projects we confined ourselves to some important german and belgian applications. in the choice of the subfield level systems, which are marc ii based, we tried to be more complete. most of the cited applications, for practical reasons, only concern the treatment of monographs. this cannot be seen as a limitation because the methods discussed are very techniques for special processing/ goossens 169 general by nature and may be used for other material. each system which has recourse to different special processing techniques is discussed in terms of each of these techniques, enabling one to get a realistic overview of the problem. in the last section, a table of the systems versus the techniques used is given. the material studied in this paper provided us with the necessary background for building an internal coding technique in our internal processing format. bibliographic element codification methods field level systems the most rudimentary projects of catalog automation are limited to a coarse division of the bibliographic description into broad fields. these are marked by special supplied codes and cover the basic elements of author, title, imprint, collation, etc. in some of the field level systems, a bibliographic element may be further differentiated according to a more specific content designation, or according to a function identification. for instance, the author element can be split up into personal name and corporate name, or a distinction can be made between a main entry, an added entry, a reference, etc. this approach supports only the treatment of each identified bibliographic element as a whole for all necessary processing operations, filing and printing included. this explains why, in certain applications, some of the bibliographic elements are duplicated, under a variant form, according to the subsequent treatments reflected in the output functions. details on this will be discussed later. here we only mention as an example the deutsche bibliographie and the project developed at the university of bochum.l-4 it is evident that these procedures are limited in their possibilities and are not economical if applied to very voluminous bibliographic files. for this reason, at the same time, more sophisticated systems, using internal coding techniques, came into existence. these allow one to perform separate operations within a bibliographic element, based on a special indication of certain character strings within the text. as there is an overlap in the types of internal coding techniques used in the field level systems and in the subfield level systems, this problem will later be studied as a whole. we limit ourselves to citing some projects falling under this heading. as german applications we have the deutsche bibliographie and the bikas system. 5 in belgium the programs of the quetelet fonds may be mentioned.6· 7 subfield level systems in a subfield level system the basic bibliographic elements, separated into fields, are further subdivided into smaller logical units called subfields. for instance, a personal name is broken into a surname, a forename, a numeration, a title, etc. such a working method provides access to smaller logical units and will greatly facilitate the functions of extraction, sup170 journal of lihm1·y automation vol. 7/3 september 1974 pression, and transposition. thus, more flexibility in the processing of the bibliographic records is obtained. as is well known, the library of congress accomplished the pioneering work in developing the marc ii format: the communications format and the internal processing format. s-n these will be called marc lc and a distinction between the two will only be made if necessary. the marc lc project originated in the context of a shared cataloging program and immediately served as a model in different national bibliographies and in public and university libraries. in this paper we will discuss bnb marc of the british national bibliography, the nypl automated bibliographic system of the new york public library, monocle of the library of the university of grenoble, canadian marc, and fbr (forma bibliothecae regiae), the internal processing format of the royal library of belgium.l2-21 in order to further optimize the coding of a bibliographic description, the library of congress also provided for each field two special codes, called indicators. the function of these indicators differs from field to field. for example, in a personal name one of the indicators describes the type of name, to wit: forename, single surname, multiple surname, and name of family. some of the indicators may act as an internal code. in spite of the well-considered structuring of the bibliographic data in the subfield level systems, not all library objectives may yet be satisfied. to reduce the remaining limitations, some approaches similar to those elaborated in field level systems are supplied. some ( nypl, marc lc internal fmmat, and canadian marc) have, or will have, in a very limited way, recourse to a procedure of duplication of subfields or fields. all cited systems, except nypl, use to a greater or lesser degree internal coding techniques. finally some subfield level systems automatically solve certain filing problems by computer algorithms. this option was taken by nypl, marc lc, and bnb marc. each of these methods will be discussed in detail in the next section. techniques for special processing of data methods for special treatment of words or characters within bibliographic text were for the most part introduced to suppmt exact file arrangement procedures and printing operations. in order to give concrete form to the following explanation, we will illustrate some complex cases. each example contains the printing form and the filing form according to specific cataloging practices for some bibliographic elements. consider the titles in examples 1, 2, and 3, and the surnames in examples 4, 5, and 6. example 1: l'automation des bibliotheques

well-known basic rules for building a sort key (the translation of lowercase characters to uppercase, the completion of numerics, etc.). our attention is directed to the character strings that file differently than they are spelled in the printing form. the methods developed to meet these problems are of a very different nature. for reasons of space, not all the examples will be reconsidered in every case; only those most meaningful for the specific application will be chosen. duplication methods we briefly repeat that this method consists of the duplication of certain bibliographic elements in variant fonns, each of them exactly corresponding to a certain type of treatment. in bochum, the title data are handled in this way. one field, called "sachtitel," contains the filing form of the title followed by the year of edition. another field, named "titelbeschreibung," includes the printing form of the title and the other elements necessary for the identification of a work (statements of authorship, edition statement, imprint, series statement, etc.). to apply this procedure to examples 1, 2, and 3, the different forms of each title respectively have to be stored in a printing field and in a sorting field. analogous procedures are, in a more limited way, employed in the deutsche bibliographie. for instance, in addition to the imprint, the name of the publisher is stored in a separate field to facilitate the creation of publisher indexes. the technique of the duplication of bibliographic elements has also been considered in subfield level systems. the nypl format furnishes a filing subfield in those fields needed for the creation of the sort key. this special subfield is generally created by program, although in exceptional cases manual input may be necessary. in the filing subfield the text is preceded by a special character indicating whether or not the subfield has been introduced manually. marc lc (internal format) and canadian marc opt for a more flexible approach in which the filing information is specified with the same precision as the other information. the sorting data are stored in complete fields containing, among others, the same subfields as the corresponding original field. because in most subfield level systems the number of different fields is much higher than in field level systems, the duplication method becomes more intricate. provision of a separately coded field for each normal field 172 j oumal of library automation vol. 7 i 3 september 197 4 which may need filing information is excluded. only one filing field is supplied, which is repeatable and stored after the other fields. in order to link the sorting fields with the original fields, specific procedures have been devised. marc lc, for instance, reserves one byte per field, the sorting field code, to announce the presence or the absence of a related sorting field. the link between the fields themselves is placed in a special subfield of the filing field. 22 in the supposition that examples 3 and 4 originate from the same bibliographical description, this method may be illustrated schematically as follows: tag 100 245 880 880 sorting field code sequence number x 1 x 1 1 2 data $a$mc kelvy $a$ibm 360 assembler language $ja$1001$mackelvy $ja$2451$i b m three hundred sixty assembler language as is well known, the personal author and title fields are coded respectively as tag 100 and tag 245. tag 880 defines a filing field. in the second column, the letter x identifies the presence of a related sorting field. the third column contains a tag sequence number needed for the unequivocal identification of a field. in the last column the sign ·$ is a delimiter. the first $ is followed by the different subfield codes. the other delimiters initiate the subsequent subfields. in tag 100 and 245, the first subfields contain the surname and the short title respectively. in tag 880 the first subfield gives the identification number of the related original field. the further subfield subdivision is exactly the same as in the original fields. in canadian marc a slightly different approach has been worked out. note that in neither of the last two projects has this technique been implemented yet. for an evaluation of the duplication method different means of application must be considered. if not systematically used for several bibliographic elements, the method is very easy at input. the cataloger can fill in the data exactly as they are; no special codes must be imbedded in the text. but it is easy to understand that a more frequent need of duplicated data renders the cataloging work very cumbersome. in regard to information processing, this method consumes much storage space. first, a certain percentage of the data is repeated; second, in the most complete approach of the subfield level systems, space is needed for identifying and linking information. for instance, in marc lc, one byte per field is provided containing the sorting field code, even if no filing information at all is present. finally, programming efforts are also burdened by the need for special linking procedures. in order to minimize the use of the duplication technique, the cited systems reduce their application in different ways. bochum simplified its cataloging rules in order to limit its use to title information. as will be explained further, the deutsche bibliographie also has recourse to internal techniques for special processing/ goossens 173 coding techniques. nypl, marc lc, and canadian marc only call on it if other more efficient methods (see later) fail. they also make an attempt to adapt existing cataloging practices to an unmodified machine handling of nonduplicated and minimally coded data. intemal coding techniques separators separators are special codes introduced within the text, identifying the characters to be treated in a special way. a distinction can be made among four procedures. 1. simple separators. with this method, each special action to be performed on a limited character string is indicated by a group of two identical separators, each represented as a single special sign. illustration on examples 2, 3, 4, and 6 gives: example 2: £ bolletino £ ¢bulletino della r. ¢accademia medica ¢di ¢roma example 3: £i b m three hundred sixty £¢ibm 360 ¢assembler language example 4: m£a£c¢ ¢kelvy example 6: martin du¢ ¢card the characters enclosed between each group of two corresponding codes £ must be omitted for printing operations. in the same way the characters enclosed between two corresponding codes ¢ are to be ignored in the process of filing. in the case that only the starting position of a special action has to be indicated, one separator is sufficient. for instance, if in example 1 we limit ourselves to coding the first character to be taken into account for filing operations, we have: example 1: l' i automation des bibliotheques where a slash is used as sorting instruction code. the simple separator method has tempting positive aspects. occupying a minimum of storage space (maximum two bytes for each instruction), the technique gives a large range of processing possibilities. indeed, excluding the limitation on the number of special signs available as separators, no other restrictions are imposed. this argument will be rated at its true worth only after evaluation of the multiple function separators method and of the indicator techniques. the major disadvantage of the simple separator method lies in its slowness of exploitation. in fact, for every treatment to be performed, each data element which may contain special codes has to be scanned, character by character, to localize the separators within the text and to enable the execution of the appropriate instructions. for example, in the case of a printing operation, the program has to identify the parts of the text to be considered and to remove all separators. the sluggishness of 17 4 i ournal of library automation vol. 7 i 3 september 197 4 execution was for some, as for canadian marc, a reason to disapprove this method.23 as already mentioned, another handicap with cataloging applications is the loss of a number of characters caused by their use as special codes. it is self-evident that each character needed as a separator cannot be used as an ordinary character in the text. for bochum this was a motive to reject this method. many of the field level systems with internal codes have recourse to simple separators. we mention the deutsche bibliographie, in which some separators indicate the keywords serving for automatic creation of indexes and others give the necessary commands for font changes in photocomposition applications. in order to reduce the number of special signs, the deutsche bibliographie also duplicates certain bibliographic data. bikas uses simple separators for filing purposes. the technique is also employed in subfield level systems. in monocle each title field contains a slash, indicating the first character to be taken into account for filing. 2. multiple function separators. designed by the british, the technique of the multiple function separators was adopted in monocle. the basic idea consists of the use of one separator characteristic for instructing multiple actions. in the case of monocle these actions are printing only, filing only, and both printing and filing. in order to give concrete form to this method we apply it to examples 3, 4, and 6, using a vertical bar as special code. example 3: jibm 360 jib m three hundred sixty jassembler language example 4: mjc jacjkelvy example 6: martin dujjjgard the so-called three-bar filing system divides a data element into the following parts: data to be j data to be i data to be filed and printed j printed only filed only i data to be j filed and printed in comparison with the simple separator technique, this method has the advantage of needing fewer special characters. a gain of storage space cannot be assumed directly. as is the case in example 6, if only one special instruction is needed, the set of three separators must still be used. on the other hand, one must note that a repetition of identical groups of multiple function separators within one data element must be avoided. subsequent use of these codes leads to very unclear representations of the text and may cause faulty data storage. this can well be proved if the necessary groups of three bars are inserted in examples 1 and 2. of the studied systems, monocle is the only one to use this method. 3. separators with indicators. as mentioned in the description of subfield level systems, two indicators are added for each field present. in techniques for special p1'0cessing/ goossens 175 order to speed up the processing time in separator applications, indicators may be exploited. in monocle the presence or the absence of three bars in a subfield is signalled by an indicator at the beginning of the corresponding field. this avoids the systematic search for separators within all the subfields that may contain special codes. the number of indicators being limited, it is self-evident that in certain fields they may already be used for other purposes. as a result, some of the separators will be identified at the beginning of the field and others not. this leads to a certain heterogeneity in the general system concept which complicates the programming efforts. under this heading, we have mentioned the use of indicators only in connection with multiple function separators. note that this procedure could be applied as well in simple separator methods. nevertheless, none of the subfield level systems performs in this fashion because it is not necessary for the particular applications. this method is not followed in the field level systems as no indicators are provided. 4. compound separators. a means of avoiding the second disadvantage of the simple separator technique is to represent each separator by a two-character code: the first one, a delimiter, identifies the presence of the separator and is common to each of them; the second one, a normal character, identifies the separator's characteristic. taking the sign £ as delimiter and indicating the functions of nonprinting and nonfiling respectively by the characters a and b, examples 2 and 4 give in this case : example 2: £ abolletino £ a£ bbulletino della r. £ baccademia medica £ bdi £ broma example 4: m£aa£ac£b £bkelvy thus the number of reserved special characters is reduced to one, independent of the number of different types of separators needed. in none of the considered projects is this technique used, probably because of the amount of storage space wasted. indicators as the concept of adding indicators in a bibliographic record format is an innovation of marc lc, the methods described under this heading concern only subfield level systems. although at the moment of the creation of marc lc one did not anticipate the systematic use of indicators for filing, its adherents made good use of them for this purpose. 1. personal name type indicator. as mentioned earlier, in marc lc one of the indicators, in the field of a personal name, provides information on the name type. this enables one to realize special file arrangements. for example, in the case of homonyms, the names consisting only of a forename can be filed before identical surnames. using the same indicator, an exact sort sequence can be obtained for 176 journal of libmry automation vol. 7/3 september 1974 single surnames, including prefixes. knowing that the printing form of example 5 is a single surname, the program for building the sort key can ignore the two spaces. the systems derived from marc lc developed analog indicator codifications adapted to their own requirements. this seems to be an elegant method for solving particular filing problems in personal names. nevertheless, its possibilities are not large enough to give full satisfaction. for instance, example 6 gives a multiple surname with prefix in the second part of the name. the statement of multiple surname in the indicator does not give enough information to create the exact sort form. because of this shortcoming, monocle had recourse to the technique called "separators with indicators." 2. indicators identifying the beginning of filing text. bnb marc reserves one indicator in the title field for identification of the first character of the title to be considered for filing. this indicator is a digit between zero and nine, giving the number of characters to be skipped at the beginning of the text. applying this technique to example i, the corresponding filing indicator must have the value three. without having recourse to other working methods, this title sorts as: example 1: automation des bibliotheques notice that the article des still remains in the filing form. this procedure has the advantage of being very economical in storage space and in processing time. moreover the text is not cluttered with extraneous characters. on the other hand we must disapprove of the limitation of this technique to the indication of nonfiling words at the beginning of a field. the possibility of identifying certain character strings within the text is not provided for. taking examples 2 and 3 we observe that the stated conditions cannot be fulfilled. another negative side is the number of characters to be ignored, which may not exceed nine. also one indicator must be available for this filing indication. after bnb marc, marc lc and canadian marc also introduced this technique. 3. separators with indicators. the use of indicators in combination with separators has been treated above. pointers a final internal coding technique which seems worth studying is the one developed at the royal library of belgium for the creation of the catalogs of the library of the quetelet fonds, a field level system. the pointer technique is rather intricate at input but has many advantages at output. because there is inadequate documentation of this working method, we will try to give an insight into it by schematizing the procedures to be followed to create the final storage structure. at input, the cataloger intechniques for special p1'dcessing/goossens 177 serts the necessary internal codes as simple separators within the text. these codes are extracted by program from the text and placed before it, at the beginning of each field. each separator, now called pointm· characteristic, is supplemented with the absolute beginning address and the length of its action area within the text. in the quetelet fonds the pointer characteristic is represented by one character, the address and length occupy two bytes each. the complete set of pointers (pointer characteristics, lengths, and addresses ) is named pointer field. this field is incorporated in a sort of directory, starting with the sign "&" identifying the beginning of the field, followed by the length of the directory, the length of the text, and the pointer field itself. this is illustrated in figure 1. note that each field contains the five first bytes, even if no pointers are present. in the quetelet fonds, pointers are used for the following purposes: nonfiling, nonprinting, kwic index, indication of a corporate name in the title of a periodical, etc. examples 2, 3, and 4 should be stored in this system as represented in figure 2. directory text i i pointer field i i i i i 1 i i i i i i i i i i i representation of the structure of a field in the internal processing format of the quetelet fonds system. the codes respectively represent: &: field delimiter; ld: length of directory; lt: length of text; x, y, . . . : pointer characteristics; ax, ay, . . . : addresses of the beginning of the related action area inside the text; lx, ly, ... : length of these action areas. fig. 1. structure of direct01y with pointe1' technique. ' the advantages of the pointer technique are numerous. first, we must mention the relative rapidity of the processing of the records. in fact, in order to detect a specific pointer, only the directory has to be consulted. all subsequent instructions can be executed immediately. in contrast with most of the other methods discussed, there is no objection to using pointers for all internal coding purposes needed. this enables one to pursue homogeneity in the storage format, facilitating the development of programs. further, the physical separation of the internal codes and the text allow, in most cases, a direct clean text representation without any reformatting. finally, unpredictable expansions of internal coding processes can easily be added without adaptation of the existing software. a great disadvantage of the pointer technique lies in the creation of the directory. the storage space occupied by the pointers is also great in comparison with the place occupied by internal codes in other methods. a further handicap is the limitation imposed at input due to the use of simple separators. 178 journal of library automation vol. 7 i 3 september 197 4 ~~2,!j5,31~4>.~ 1,~eb ,4>11 ,9lel4,61ct;,3jb.o,l,l,e,t, i,n.o, ,b,u, i, i ,e, t, i ,n,oj 0 5 10 15 ,d,e,l,l,a, ,r,., ,a,c,c,a,d,e,m,i,a, ,m,e,d,i,c,a, ,d:i, ,r,o,m,a,$ ~ ~ ~ ~ ~ ~ ~ ~ ~~1 ,5 1 5,2~a~,$1 2,61sl2,6 1ci>, eli, ,b, ,m, ,t,h,r,e,e, ,h,u,n,d,r,e,d, ,s, i ,x,rl 0 5 10 15 ~ lv, , i,b,m, ,3,6,4>, ,a,s,s,e,m,b, i ,e, r, , i ,a,n,g,u,a,g,e, ~ ~ ~ h ~ ~ ~~ ~~1 ,5,4>,91~4>, 114>,1lelc~>,3 1 ci>, 1jm,a,c, ,k,e, l ,v,y, ~ 0 5 8 representation of examples 2, 3, and 4 in the quetelet fonds format. a represents the pointer characteristic for nonprinting data;

microsoft word 9733-16966-4-ce.docx editorial board thoughts: arts into science, technology, engineering, and mathematics – steam, creative abrasion, and the opportunity in libraries today tod colegrove information technologies and libraries | march 2017 4 over the millennia, man’s attempt to understand the universe has been an evolution from the broad to the sharply focused. a wide range of distinctly separate disciplines evolved from the overarching natural philosophy, the study of nature, of greco-roman antiquity: anatomy and astronomy through botany, mathematics, and zoology among many others. similarly, the arts, humanities, and engineering developed from broad over-arching interest into tightly focused disciplines that today are distinctly separate. as these legitimate divisions formed, grew, and developed into ever-deepening specialty, they enabled correspondingly deeper study and discovery1; in response, the supporting collections of the library divided and grew to reflect that increasing complexity. libraries have long been about the organization of, and access to, information resources. subject classification systems in use today, such as the dewey decimal system, are designed to group like items with like, albeit under broad overarching topic. a perhaps inevitable result for print collections housed under such a classification system is the physical isolation of items and, by extension, the individuals researching those topics from one another. under the library of congress system, for example, items categorized as “geography” are physically removed from those in “science;” further still from “technology.” end-users benefit from the possibility of serendipitous discovery while browsing shelves nearby, even as they are effectively shielded from exposure to distracting topics outside of their immediate focus. recent years have witnessed a rediscovery of, and renewed interest in, the fundamental role the library can have in the creation of knowledge, learning, and innovation among its members. as collections shift from print to electronic, libraries are increasingly less bound to the physical constraints imposed by their print collections. rather than a continued focus on hyperspecialization and separation, we have the opportunity to rethink the library: exploring novel configurations and services that might better support its community, and embracing emerging roles of trans-disciplinary collaboration and innovation. the library as intersection libraries reflect the institutional and organizational structures of their communities, even as the tod colegrove (pcolegrove@unr.edu), a member of the ital editorial board, is head of delamare science & engineering library, university of nevada, reno. editorial board thoughts | colegrove https://doi.org/10.6017/ital.v36i1.9733 5 physical organization of the structures built to house print collections mirror the classification system in use. academic libraries are perhaps most entrenched in the structural division: rather than intrinsically promoting collaboration and discovery across disciplines, the organization of print collections, and typically the spaces around them, is designed to foster increased focus and specialization. specialized almost to the exclusion of other areas of study altogether, in branch libraries of a college or university this division can reach a pinnacle; libraries and collections devoted to exclusive topics of engineering, science, music, and others, exist on campuses across the country. amplified by separation and clustering of faculty and researchers, typically by department and discipline, it becomes entirely possible for individuals to “spend a lifetime working in a particular narrow field and never come into contact with the wider context of his or her study.”2 the library is also one of the few places in any community where individuals from a variety of backgrounds and specialties can naturally cross paths with one another. at a college or university, students and faculty from one discipline might otherwise rarely encounter those from other disciplines. whether public, school, or academic library, outside of the library individuals and groups are typically isolated from one another physically, with little opportunity to interact organically. without active intervention and deliberate effort on the part of the library, opportunities for creative abrasion3 and trans-disciplinary collaboration become virtually nonexistent; its potential to “unleash the creative potential that is latent in a collection of unlikeminded individuals,”4 untapped. leveraged properly, however, the intersection of interests and expertise that occurs naturally within the neutral spaces of the library can become a powerful tool that supports not only research, but creativity and innovation a place where ideas and viewpoints can collide, building on one another: “for most of us, the best chance to innovate lies at the intersection. not only do we have a greater chance of finding remarkable idea combinations there, we will also find many more of them.... the explosion of remarkable ideas is what happened in florence during the renaissance, and it suggests something very important. if we can just reach an intersection of disciplines or cultures, we will have a greater chance of innovating, simply because there are so many unusual ideas to go around.”5 difficult and scary the problem? “stimulating creative abrasion is difficult and scary because we are far more comfortable being with folks like us.”6 and yet a quick review of the literature reveals that knowledge creation, innovation, and success are inextricably linked7, with the fundamental understanding of their connection having undergone a dramatic shift: “knowledge is in fact essential to innovate, and while this might sound obvious today, putting knowledge and innovation and not physical assets at the centre of competitive advantage was a tremendous change.”8 as our libraries move toward embracing an even more active role within our communities, our organizational priorities are undergoing similarly dramatic shifts: support for knowledge creation information technologies and libraries | march 2017 6 and innovation becomes more central, even as physical assets shift toward a supporting, even peripheral, role. libraries, as fundamentally neutral hubs of diverse communities, are uniquely positioned to be able to cultivate creative abrasion within and among their communities, fostering not only knowledge creation, but innovation and success. indeed, the combination of physical, electronic, and staff assets can be the raw stuff by which trans-disciplinary engagement is encouraged. the active cultivation and support of creative abrasion, with direct linkage to desired outcomes, becomes arguably one of the most vital services the library can provide its community. rather than deepening the cycle of hyper-specialization, the emergence of makerspace in our libraries is one example of a trend toward enabling libraries to broaden and embrace that support. building on the intellectual diversity within the spaces of the library, staff members, volunteers, and fellow community members can serve as catalyst, triggering groups to “do something with that variety”9 by engaging across traditional boundaries. indeed, “by deliberately creating diverse organizations and explicitly helping team members appreciate thinking-styles different than their own, creative abrasion can result in successful innovation.”10 strategic placement and staff support of makerspace activity can dramatically increase the opportunity for creative abrasion and, by extension, the resulting knowledge creation, creativity and innovation. arts bring a fundamental literacy and resource to stem in recent years, greater emphasis on students acquiring stem (science, technology, engineering, and math) skills has raised the topic to be one of the most central issues in education. considered a key solution to improving the competitiveness of american students on the global stage, the approach of stem education shares the common goal of breaking down the artificial barriers that exist even within the separate disciplines of sciences, technology, engineering, and math in short, increasing the diversity of the learning environment. proponents of steam go further by suggesting that adding art into the mix can bring new energy and language to the table, “sparking curiosity, experimentation, and the desire to discover the unknown in students.” 11 federal agencies such as the u.s. department of education and the national science foundation have funded and underwritten a number of grants, conferences, and workshops in the field, including the seminal forum hosted by the rhode island school of design (risd), “bridging stem to steam: developing new frameworks for art-science-design pedagogy.”12 john maeda, the president of the risd, identifies a direct connection between the approach and the creativity and success of late apple co-founder steve jobs, with steam support “a pathway to enhance u.s. economic competitiveness.”13 proponents go further, arguing the arts bring both a fundamental literacy and resource to the stem disciplines, providing “innovations through analogies, models, skills, structures, techniques, methods, and knowledge.”14 consider the findings of a study of nobel prize winners in the sciences, members of the royal society, and the u.s. national academy of sciences; nobel laureates were: editorial board thoughts | colegrove https://doi.org/10.6017/ital.v36i1.9733 7 twenty-five times as likely as an average scientist to sing, dance, or act; seventeen times as likely to be an artist; twelve times more likely to write poetry and literature; eight times more likely to do woodworking or some other craft; four times as likely to be a musician; and twice as likely to be a photographer.15 from the standpoint of creative abrasion, welcoming the “a” of art into the library support of stem disciplines increases the diversity of the library, and by default the opportunity for creative abrasion. from aristotle and pythagoras through galileo galilei and leonardo da vinci to benjamin franklin, richard feynman, and noam chomsky, a long list of individuals of wideranging genius hints at a potential left largely untapped by our traditional approach. connections between stem disciplines, art, and the innovation arising directly out of their creative abrasion surround us: the electronic screens used on a wide range of technology, including computers, televisions, and cell phones, are the result of a collaboration between a series of painter-scientists and post-impressionist artists such as seurat a combination of red, green, and blue dots generate full-spectrum images in a way not unlike that of the artistic technique of pointillism. the electricity to drive that technology is understood, in part, due to early work by franklin even as he lay the foundations of the free public library with the opening of america’s first lending library, and pursued a broad range of parallel interests. the stitches used in medical surgery are the result of nobel laureate alexis carrel taking his knowledge of lace making from a traditional arena into the operating room. prominent american inventors “samuel morse (telegraph) and robert fulton (steam ship) were among the most prominent american artists before they turned to inventing.”16 in short, “increasing success in science is accompanied by developed ability in other fields such as the fine arts.”17 rather than isolated in monastic study, “almost all nobel laureates in the sciences are actively engaged in arts as adults.”18 perhaps surprisingly, rather than being rewarded by an ever-increasing focus and hyper-specialization, genius in the sciences seems tied to individuals’ activity in the arts and crafts. the study’s authors cite three different nobel prize winners, including j. h. van’t hoff’s 1878 speculation that scientific imagination is correlated with creative activities outside of science19; going on to detail similar findings from general studies dating back over a century. of even more seminal interest, the authors point to a similar connection for adolescents/young adults where milgram and colleagues20 found “having at least one persistent and intellectually stimulating hobby is a better predictor of career success in any discipline than iq, standardized test scores, or grades.”21 discussion the connection between individuals holding a multiplicity of interests, trans-disciplinary activity, and success is clear; what is less clear is to what extent we are fostering that connection in our libraries today. the potential is nevertheless tantalizing: a random group of people, thrown together, is not likely to be very creative. by going beyond specialization and wading into the information technologies and libraries | march 2017 8 deeper waters of supporting and cultivating creative abrasion and avocation among the membership of our libraries, we are fostering success and innovation beyond what might otherwise occur. the decision to catalyze and foster the cross-curricular collaboration that is steam22 is squarely in the hands of the library: in the design of its spaces, and in the interactions of the staff of the library with the communities served. we can choose to actively connect and catalyze across traditional boundaries. as the head of a science and engineering library, one of the early adopters of makerspace and actively exploring the possibilities of steam engagement for several years, i have time and again witnessed the leaps of insight and creativity brought about by creative abrasion. from across disciplines members are engaging with the resources of the library and, with our encouragement, one another in an ever-increasing cycle of knowledge creation, innovation, and success. the impact is particularly dramatic among individuals from strongly differing backgrounds and disciplines: for example, when an engineering student, who considers themselves to be expert with a particular technology, witnesses and interacts with an art student using that same technology and accomplishing something truly unexpected, even seemingly magical. or when a science student approaching a problem from one perspective realizes a practitioner from a different discipline sees the problem from an entirely different, and yet equally valid, point of view. in each case, it’s as if the worldview of each suddenly melts: shifting and expanding, never to return to its original shape. transformative experiences become the order of the day, even as the informal environment offers a wealth of opportunity to engage with and connect end-users to the more traditional resources of library. by actively seeking out opportunities to bring art into traditionally stem-focused activity, and vice-versa, we are deliberately increasing the diversity of the environment. makerspace services and activities, to the extent they are open and visibly accessible to all, are a natural for the spontaneous development of trans-disciplinary collaboration. within the spaces of the library, opportunities to connect individuals around shared avocational interest might range from music and spontaneous performance areas to spaces salted with lego bricks and jigsaw puzzles; the potential connections between our resources and the members of our communities are as diverse as their interests. indeed, when a practitioner from one discipline can interact and engage with others from across the steam spectrum, the world becomes a richer place – and maybe, just maybe, we can fan the flames of curiosity along the way. references 1. bohm, d., and f. d. peat. 1987. science, order, and creativity: a dramatic new

academic libraries ruth sara connell information technology and libraries | june 2013 42 abstract academic libraries, and their parent institutions, are increasingly using content management systems (cmss) for website management. in this study, the author surveyed academic library web managers from four-year institutions to discover whether they had adopted cmss, which tools they were using, and their satisfaction with their website management system. other issues, such as institutional control over library website management, were raised. the survey results showed that cms satisfaction levels vary by tool and that many libraries do not have input into the selection of their cms because the determination is made at an institutional level. these findings will be helpful for decision makers involved in the selection of cmss for academic libraries. introduction as library websites have evolved over the years, so has their role and complexity. in the beginning, the purpose of most library websites was to convey basic information, such as hours and policies, to library users. as time passed, more and more library products and services became available online, increasing the size and complexity of library websites. many academic library web designers found that their web authoring tools were no longer adequate for their needs and turned to cmss to help them manage and maintain their sites. for other web designers, the choice was not theirs to make. their institution transitioned to a cms and required the academic library to follow suit, regardless of whether the library staff had a say in the selection of the cms or its suitability for the library environment. the purpose of this study was to examine cms usage within the academic library market and to provide librarians quantitative and qualitative knowledge to help make decisions when considering switching to, or between, cmss. in particular, the objectives of this study were to determine (1) the level of saturation of cmss in the academic library community; (2) the most popular cmss within academic libraries, the reasons for the selection of those systems, and satisfaction with those cmss; (3) if there is a relationship between libraries with their own dedicated information technology (it) staff and those with open source (os) systems; and (4) if there is a relationship between institutional characteristics and issues surrounding cms selection. ruth sara connell (ruth.connell@valpo.edu) is associate professor of library services and electronic services librarian, christopher center library services, valparaiso university, valparaiso, in. mailto:ruth.connell@valpo.edu content management systems: trends in academic libraries | connell 43 although this study largely focuses on cms adoption and related issues, the library web designers who responded to the survey were asked to identify what method of web management they use if they do not use a cms and asked about satisfaction with their current system. thus, information regarding cms alternatives (such as adobe’s dreamweaver web content editing software) is also included in the results. as will be discussed in the literature review, cmss have been broadly defined in the past. therefore, for this study participants were informed that only cmss used to manage their primary public website were of interest. specifically, cmss were defined as website management tools through which the appearance and formatting is managed separately from content, so that authors can easily add content regardless of web authoring skills. literature review most of the library literature regarding cms adoption consists of individual case studies describing selection and implementation at specific institutions. there are very few comprehensive surveys of library websites or the personnel in charge of academic library websites to determine trends in cms usage. the published studies including cms usage within academic libraries do not definitively answer whether overall adoption has increased. in 2005 several georgia state university librarians surveyed web librarians at sixty-three of their peer institutions, and of the sixteen responses, six (or 38 percent) reported use of “cms technology to run parts of their web site.” 1 a 2006 study of web managers from wide range of institutions (associates to research) indicated a 26 percent (twenty-four of ninety-four) cms adoption rate.2 a more recent 2008 study of institutions of varying sizes resulted in a little more than half of respondents indicating use of cmss, although the authors note that “people defined cmss very broadly,” 3 including tools like moodle and contentdm, and some of those libraries indicated they did not use the cms to manage their website. a 2012 study by comeaux and schmetzke differs from the others mentioned here in that they reviewed academic library websites of the fifty-six campuses offering ala-accredited graduate degrees (generally larger universities) and used tools and examined page code to try to determine on their own if the libraries used cmss, as opposed to polling librarians at those institutions to ask them to self-identify if they used cmss. they identified nineteen out of fifty-six (34 percent) sites using cmss. the authors offer this caveat, “it is very possible that more sites use cmss than could be readily identified. this is particularly true for ‘home-grown’ systems, which are unlikely to leave any readily discernible source code.” 4 because of different methodologies and population groups studied in these studies, it is not possible to draw conclusions regarding cms adoption rates within academic libraries over time using these results. as mentioned previously, some people define cmss more broadly than others. one example of a product that can be used as a cms, but is not necessarily a cms, is springshare’s libguides. many libraries use libguides as a component of their website to create guides. however, some libraries have utilized the product to develop their whole site, in effect using it as a cms. a case study by information technology and libraries | june 2013 44 two librarians at york college describes why they chose libguides as their cms instead of as a more limited guide creation tool.5 several themes recurred throughout many of the case study articles. one common theme was the issue of lack of control and problems of collaboration between academic libraries and the campus entities controlling website management. amy york, the web services librarian at middle tennessee state university, described the decision to transition to a cms in this way, “and while it was feasible for us to remain outside of the campus cms and yet conform to the campus template, the head of the it web unit was quite adamant that we move into the cms.” 6 in a study by bundza et al., several participants who indicated dissatisfaction with website maintenance mentioned “authority and decision-making issues” as well as “turf struggles.” 7 other articles expressed more positive collaborative experiences. morehead state university librarians kmetz and bailey noted, “when attending conferences and hearing the stories of other libraries, it became apparent that a typical relationship between librarians and a campus it staff is often much less communicative and much less positive than [ours]. because of the relatively smooth collaborative spirit, a librarian was invited in 2003 to participate in the selection of a cms system.” 8 kimberley stephenson also emphasized the advantageous relationships that can develop when a positive approach is used, “rather than simply complaining that staff from other departments do not understand library needs, librarians should respectfully acknowledge that campus web developers want to create a site that attracts users and consider how an attractive site that reflects the university’s brand can be beneficial in promoting library resources and services.” 9 however, earlier in the article she does acknowledge that the iterative and collaborative process between the library and their university relations (ur) department was occasionally contentious and that the web services librarian notifies ur staff before making changes to the library homepage.10 another common theme in the literature was the reasoning behind transitioning to a cms. one commonly cited criterion was access control or workflow management, which allows site administrators to assign contributors editorial control over different sections of the site or approve changes before publishing.11 however, although this feature is considered a requirement by many libraries, it has its detractors. kmetz and bailey indicated that at morehead state university, “approval chains have been viewed as somewhat stifling and potentially draconian, so they have not been activated.” 12 these studies greatly informed the questions used and development of the survey instrument for this study. method in designing the survey instrument, questions were considered based on how they informed the objectives of the study. to simplify analysis, it was important to compile as comprehensive a list of content management systems: trends in academic libraries | connell 45 cmss as possible. this list was created by pulling cms names from the literature review, the web4lib discussion list, and the cmsmatrix website (www.cmsmatrix.org). in order to select institutions for distribution, the 2010 carnegie classification of institutions of higher education basic classification lists were used.13 the author chose to focus on three broad classifications: 1. research institutions consisting of the following carnegie basic classifications: research universities (very high research activity), research universities (high research activity), and dru: doctoral/research universities. 2. master’s institutions consisting of the following carnegie basic classifications: master's colleges and universities (larger programs), master's colleges and universities (medium programs), master's colleges and universities (smaller programs). 3. baccalaureate institutions consisting of the following carnegie basic classifications: baccalaureate colleges—arts & sciences and baccalaureate colleges—diverse fields. the basic classification lists were downloaded into excel with each of the three categories in a different worksheet, and then each institution was assigned a number using the random number generator feature within excel. the institutions were then sorted by those numbers creating a randomly ordered list within each classification. to determine sample size for a stratified random sampling, ronald powell’s “table for determining sample size from a given population” 14 (with a .05 degree of accuracy) was used. each classification’s population was considered separately, and the appropriate sample size chosen from the table. the population size of each of the groups (total number of institutions within that carnegie classification) and the corresponding sample sizes were • research: population = 297, sample size = 165; • master’s: population = 727, sample size = 248; • baccalaureate: population = 662, sample size = 242. the total number of institutions included in the sample size was 655. the author then went through the list of selected institutions and searched online to find their library webpages and find the person most likely responsible for the library’s website. during this process, there were some institutions, mostly for-profits, for which a library website could not be found. when this occurred, that institution was eliminated and the next institution on the list used in its place. in some cases, the person responsible for web content was not easily identifiable; in these cases an educated guess was made when possible, or else the director or a general library email address was used. the survey was made available online and distributed via e-mail to the 655 recipients on october 1, 2012. reminders were sent on october 10 and october 18, and the survey was closed on october 26, 2012. out of 655 recipients, 286 responses were received. some of those responses http://www.cmsmatrix.org/ information technology and libraries | june 2013 46 had to be eliminated for various reasons. if two responses were received from one institution, the more complete response was used while the other response was discarded. some responses included only an answer to the first question (name of institution or declination of that question to answer demographic questions) and no other responses; these were also eliminated. once the invalid responses were removed, 265 remained, for a 40 percent response rate. before conducting an analysis of the data, some cleanup and standardization of results was required. for example, a handful of respondents indicated they used a cms and then indicated that their cms was dreamweaver or adobe contribute. these responses were recoded as non-cms responses. likewise, one respondent self-identified as a non-cms user but then listed drupal as his/her web management tool and this was recoded as a cms response. demographic profile of respondents for the purposes of gathering demographic data, respondents were offered two options. they could provide their institution’s name, which would be used solely to pair their responses with the appropriate carnegie demographic categories (not to identify them or their institution), or they could choose to answer a separate set of questions regarding their size, public/private affiliation, and basic carnegie classification. the basic carnegie classification of the largest response group was master’s with 102 responses (38 percent); then baccalaureate institutions (94 responses or 35 percent), and then research institutions (69 responses or 26 percent). this correlates pretty closely with the distribution percentages, which were 38 percent master’s (248 out of 655), 37 percent baccalaureate (242 out of 655), and 25percent research (165 out of 655). of the 265 responses, 95 (36 percent) came from academic librarians representing public institutions and 170 (64 percent) from private. of the private institutions, the vast majority (166 responses or 98 percent) were not-for-profit, while 4 (2 percent) were for-profits. to define size, the carnegie size and setting classification was used. very small institutions are defined as less than 1,000 full-time equivalent (fte) enrollment, small is 1,000–2,999 fte, medium is 3,000–9,999 fte, and large is at least 10,000 fte. the largest group of responses came from small institutions (105 responses or 40 percent), then medium (67 responses or 25 percent), large (60 responses or 23 percent), and very small (33 responses or 12 percent). results the first question asking for institutional identification (or alternative routing to carnegie classification questions) was the only question for which an answer was required. in addition, because of question logic, some people saw questions that others did not based on how they answered previous questions. thus, the number of responses varies for each question. one of the objectives of this study was to identify if there were traits among institutional characteristics and cms selection and management. the results that follow include both content management systems: trends in academic libraries | connell 47 descriptive statistics and statistically significant inferential statistics discovered using chi-square and fisher’s exact tests. statistically significant results are labeled as such. the responses to this survey show that most academic libraries are using a cms to manage their main library website (169out of 265 responses or 64 percent). overall, cms users expressed similar (although slightly greater) satisfaction levels with their method of web management (see table 1.) table 1 satisfaction by cms use use a cms to manage library website yes no user is highly satisfied or satisfied yes 79 responses or 54% 41 responses or 47% no 68 responses or 46% 46 responses or 53% total 147 responses or 100% 87 responses or 100% non-cms users non-cms users were asked what software or system they use to govern their site. by far, the most popular system mentioned among the 82 responses was adobe dreamweaver, with 24 (29 percent) users listing it as their only or primary system. some people listed dreamweaver as part of a list of tools used; for example “php / mysql, integrated development environments (php storm, coda), dreamweaver, etc.,” and if all mentions of dreamweaver are included, the number of users rises to 31 (38 percent). some version of “hand coded” was the second most popular answer with 9 responses (11 percent), followed by adobe contribute with 7 (9 percent). many of the “other” responses were hard to classify and were excluded from analysis. some examples include: • ftp to the web • voyager public web browser ezproxy • excel, e-mail, file folders on shared drives among the top three non-cms web management systems, dreamweaver users were most satisfied, selecting highly satisfied or satisfied in 15 out of 24 (63 percent) cases. hand coders were highly satisfied or satisfied in 5out of 9 of cases (56 percent), and adobe contribute users were only highly satisfied or satisfied in 3 out of 7 (43 percent) cases. respondents not using a cms were asked whether they were considering a move to a cms within the next two years. most (59 percent) said yes. research libraries were much more likely to be planning such a move (81percent) than master’s (50 percent) or baccalaureate (45 percent) libraries (see table 2.) a chi-square test rejects the null hypothesis that the consideration of a move to cms is independent of basic carnegie classification; this difference was significant at the p = 0.038 level. information technology and libraries | june 2013 48 table 2 non-cms users considering a move to a cms within the next two years by carnegie

provide comments related to topics covered in the survey, and here is a sampling of responses received: • cmss cost money that our college cannot count on being available on a yearly basis. • the library doesn't have overall responsibility for the website. university web services manages the entire site, i submit changes to them for inclusion and updates. • we are so small that the time to learn and implement a cms hardly seems worth it. so far this low-tech method has worked for us. • the main university site was moved to a cms in 2008. the library was not included in that move because of the number of pages. i hear rumors that we will be forced into the cms that is under consideration for adoption now. the library has had zero input in the selection of the new cms. cms users when respondents indicated their library used a cms, they were routed to a series of cms related questions. the first question asked which cms their library was using. of the 153 responses, the most popular cmss were drupal (40); wordpress (15); libguides (14), which was defined within the survey as a cms “for main library website, not just for guides”; cascade server (12); ektron (6); and modx and plone (5 each). these users were also asked about their overall satisfaction with their systems. among the top four cmss, libguides users were the most satisfied, selecting highly satisfied or satisfied in 12 out of 12 (100 percent) cases. the remaining three systems’ satisfaction ratings (highly satisfied or satisfied) were as follows: wordpress (12out of 15 cases or 80 percent), drupal (26out of 38 cases or 68 percent), and cascade server (3 out of 11 cases or 27 percent). when asked whether they would switch systems if given the opportunity, most (61out of 109 cases or 56 percent) said no. looking at the responses for the top four cmss, responses echo the content management systems: trends in academic libraries | connell 49 satisfaction responses. libguides users were least likely to want to switch (0 out of 7 cases or 0 percent), followed by wordpress (1 out of 5 cases or 17 percent), drupal (8out of 23 cases or 26 percent), and cascade server (3 out of 7 or 43 percent) users. respondents were asked whether their library uses the same cms as their parent institution. most (106 out of 169 cases or 63 percent) said yes. libraries at large institutions (over 10,000 fte) were much less likely (34 percent) than their smaller counterparts to share a cms with their parent institution (see table 3.) a chi-square test rejects the null hypothesis that sharing a cms with a parent institution is independent of size: at a significance level of p = 0.001, libraries at smaller institutions are more likely to share a cms with their parent. table 3 cms users whose libraries

more likely to share cmss with their institutions (69 percent and 71 percent respectively) than research libraries (42 percent) (see table 4.) at a significance level of p = 0.004, a chi-square test

parent institution. most (80 out of 99 cases or 81 percent) said yes, the transition was made together. however, private institutions were more likely to have made the switch together (88 percent) than public (63 percent) (see table 5.) a fisher’s exact test rejects the null hypothesis that transition to cms is independent of institutional control: at a significance level of p = 0.010, private

to a cms with their parent institution, the transition was usually forced. out of the 88 libraries that transitioned together and indicated whether they were given a choice, only 8 libraries (9 percent) had a say in whether to make that transition. and even though academic libraries were usually forced to transition with their institution, they did not usually have representation on campus-wide cms selection committees. only 25 percent (22 out of 87) respondents indicated that their library had a seat at the table during cms selection. when comparing cms satisfaction ratings among libraries that were represented on cms selection committees versus those that had no representation, it is not surprising that those with representation were more satisfied (13 out of 22 cases or 59 percent) than those without (21 out of 59 cases or 36 percent). the same holds true for those libraries given a choice whether to transition. those given a choice were satisfied more often (6out of 8 cases or 75 percent) than those forced to transition (21 out of 71 cases or 30 percent). respondents who said that they were not on the same cms as their institution were asked why they chose a different system. many of the responses indicated a desire for freedom from the controlling influence of either it and marketing arms of the institution : • we felt drupal offered more flexibility for our needs than cascade, which is what the university at large was using. i've heard more recently that the university may be considering switching to drupal. • university pr controls all aspects of the university cms. we want more freedom. • we are a service-oriented organization, as opposed to a marketing arm. we by necessity need to be different. cms users were asked to provide a list of three factors most important in their selection of their cms and to rank their list in order of importance. the author standardized the responses, e.g. “price” was recorded as “cost.” the factors listed first, in order of frequency, were ease of use (15), flexibility (10), and cost (6). ignoring the ranking, 38 respondents listed ease of use somewhere in their “top three”, while 23 listed cost, and 16 listed flexibility. another objective of this study was to determine if there was a positive correlation between libraries with their own dedicated it staff and those who chose open source cmss. therefore cms users were asked if their library had its own dedicated it staff, and 66 out of 143 libraries (46 percent) said yes. then the cmss used by respondents were translated into two categories, open source or proprietary systems (when a cms listed was unknown it was coded as a missing value), and a fisher’s exact test was run against all cases that had values for both variables to see if a correlation existed. although those with library it had open source systems more frequently than those without, the difference was not significant (see table 7.) information technology and libraries | june 2013 52 table 7 libraries with own it personnel by open source cmss library has own it yes no total cms is open source yes 37 responses (73%) 32 responses (57%) 69 responses (65%) no

100% in another question, people were asked to self-identify if their organization uses an open source cms, and if so asked whether they have outsourced any of its implementation or design to an outside vendor. most (61 out of 77 cases or 79 percent) said they had not outsourced implementation or design. one person commented, “no, i don't recommend doing this. the cost is great, you lose the expertise once the consultant leaves, and the maintenance cost goes through the roof. hire someone fulltime or move a current position to be the keeper of the system.” one of the advantages of having a cms is the ability to give multiple people, regardless of their web authoring skills, the opportunity to edit webpages. therefore, cms users were asked how many web content creators they have within their library. out of 152 responses, the most frequent range cited was 2–5 authors (72 responses or 47 percent), followed by (33 responses or 22 percent) with only one author, 6–10 authors (20 responses or 13 percent), 21–50 authors (16 responses or 11 percent), 11–20 authors (6 responses or 4 percent), and over 50 authors (5 responses or 3 percent). because this question was an open ended response and responses varied greatly, including “over 100 (over 20 are regular contributors)” and “1–3”, standardization was required. when a range or multiple numbers were provided, the largest number was used. respondents were asked whether their library uses a workflow management process requiring page authors to receive approval before publishing content. of the 131 people who responded yes or no, most (88 responses or 67 percent) said no. cms users were asked to provide comments related to topics covered in the survey. many comments mentioned issues of control (or lack thereof), while another common theme was concerns with specific cmss. here is a sampling of responses received: • having dedicated staff is a necessity. there was a time when these tools could be installed and used by a techie generalist. those days are over. a professional content person and a professional cms person are a must if you want your site to look like a professional site... content management systems: trends in academic libraries | connell 53 i'm shocked at how many libraries switched to a cms yet still have a site that looks and feels like it was created 10 years ago. • since the cms was bred in-house by another university department, we do not have control over changing the design or layout. the last time i requested a change, they wanted to charge us. • our university marketing department, which includes the web team, is currently in the process of switching [cmss]. we were not invited to be involved in the selection process for a new cms, although they did receive my unsolicited advice. • we compared costs for open source and licensed systems, and we found the costs to be approximately equivalent based on the development work we would have needed in an open source environment. • the library was not part of the original selection process for the campus' first cms because my position didn't exist at that time. now that we have a dedicated web services position, the library is considered a "power user" in the cms and we are often part of the campus wide discussions about the new cms and strategic planning involving the campus website. • we currently do not have the preferred level of control over our library website; we fought for customization rights for our front page, and won on that front. however, departments on campus do not have permission to install or configure modules, which we hope will change in the future. • there’s a huge disconnect between it /administration and the library regarding unique needs of the library in the context of web-based delivery of information. discussion comparing the results of this study to previous studies indicates that cms usage within academic libraries is rising. the 64 percent cms adoption rate found in this survey, which used a more narrow definition of cms than some previous studies cited in the literature review, is higher than adoption rates in any of said studies. as more libraries make the transition, it is important to know how different cmss have been received among their peers. although cms users are slightly more satisfied than non-cms users (54 percent vs. 47 percent), the tools used matter. so if a library using dreamweaver to manage their site is given an option of moving with their institution to a cms and that cms is cascade server, they should strongly consider sticking with their current non-cms method based on the respective satisfaction levels reported in this study (63 percent vs. 27 percent). satisfaction levels are important, but should not be considered in a vacuum. for example, although libguides users reported very high satisfaction levels (100 percent were satisfied or very satisfied), users were mostly (11 out of 14 users or 79 percent) small or very small schools, while the remaining three (21percent) were medium schools. no large schools reported using libguides as their cms. libguides may be wonderful for a smaller school without need of much information technology and libraries | june 2013 54 customization or, in some cases, access to technical expertise but may not be a good cms solution for larger institutions. one of the largest issues raised by survey respondents was libraries’ control, or lack thereof, when moving to a campus-selected cms. given the complexity of academic libraries websites, library representation on campus-wide cms selection committees is warranted. not only are libraries more satisfied with the results when given a say in the selection, but libraries have special needs when it comes to website design that other campus units do not. including library representation ensures those needs are met. some of the respondents’ comments regarding lack of control over their sites are disturbing to libraries being forced or considering a move to a campus cms. clearly, having to pay another campus department to make changes to the library site is not an attractive option for most libraries. nor should libraries have to fight for the right or ability to customize their home pages. developing good working relationships with the decision makers may help prevent some of these problems, but likely not all. this study indicates that it is not uncommon for academic libraries to be forced into cmss, regardless of the cmss acceptability to the library environment. conclusion the adoption of cmss to manage academic libraries’ websites is increasing, but not all cmss are created equal. when given input into switching website management tools, library staff have many factors to take into consideration. these include, but are not limited to, in-house technical expertise, desirability of open source solutions, satisfaction of peer libraries with considered systems, and library specific needs, such as workflow management and customization requirements. ideally, libraries would always be partners at the table when campus-wide cms decisions are being made, but this study shows that this does not happen in most cases. if a library suspects that it is likely to be required to move to a campus-selected system, its staff should be alert for news of impending changes so that they can work to be involved at the beginning of the process to be able to provide input. a transition to a bad cms can have long-term negative effects on the library, its users, and staff. a library’s website is its virtual “branch” and vitally important to the functioning of the library. the management of such an important component of the library should not be left to chance. references

online e-journal databases enable scholars to search the literature in a research domain or to crosssearch an interdisciplinary field. the key literature can thereby be efficiently mapped. this study builds a web-based citation analysis system consisting of four modules: (1) literature search; (2) statistics; (3) articles analysis; and (4) co-citation analysis. the system focuses on the pubmed central dataset and facilitates specific keyword searches in each research domain for authors, journals, and core issues. in addition, we use data mining techniques for co-citation analysis. the results could help researchers develop an in-depth understanding of the research domain. an automated system for co-citation analysis promises to facilitate understanding of the changing trends that affect the journal structure of research domains. the proposed system has the potential to become a value-added database of the healthcare domain, which will benefit researchers. introduction healthcare is a multidisciplinary research domain of medical services provided both inside and outside a hospital or clinical setting. article retrieval for systematic reviews in the domain is much more elusive than retrieval for reviews in clinical medicine because of the interdisciplinary nature of the field and the lack of a significant body of evaluative literature. other connecting research fields consist of the respective research fields of the application domain (i.e., the health sciences, including medicine and nursing).1 in addition, valuable knowledge and methods can be taken from the fields of psychology, the social sciences, economics, ethics, and law. further, the integration of those disciplines is attracting increasing interest.2 researchers may use bibliometrics to evaluate the influence of a paper or describe the relationship between citing and cited papers. citation analysis, one of several possible bibliometric approaches, is more popular than others because of the advent of information technologies.3 citation analysis counts the frequency of cited papers from a set of citing papers to determine the most influential scholars, publications, or universities in a discipline. it can be classified into two basic types: the first type counts only the citations in a paper that are authored by an individual, while the second mailto:kcchu@ntunhs.edu.tw mailto:sklu@sce.pccu.edu.tw mailto:wenyi@ntunhs.edu.tw identifying emerging issues in the healthcare domain | chu, lu, and liu 40 https://doi.org/10.6017/ital.v37i1.9595 type analyzes co-citations to identify intellectual links among authors in different articles. this paper focuses on the second type of citation analysis. small defined co-citation analysis as “the frequency with which two items of earlier literature are cited together by the later literature.”4 it is not only the most important type of bibliometric analysis, but also the most sophisticated and popular method. many other methods originate from citation analysis, including document co-citation analysis, bibliographic coupling,5 author cocitation analysis,6 and co-word analysis.7 there are levels of co-citation analysis: document, author, and journal. co-citation could be used to establish a cluster or “core” of earlier literature.8 the pattern of links between documents can establish a structure to highlight the relationship of research areas. citation patterns change when previously less-cited papers are cited more frequently, or old papers are no longer cited. changing citation patterns imply the possibility of new developments in research areas; furthermore, we can investigate changing patterns to understand the scientific trend within a research domain.9 co-citation analysis can help obtain a global overview of research domains.10 the aim of this paper is to detect emerging issues in the healthcare research domain via citation network analysis. our results can provide a basis for knowledge that researchers can use to construct a search strategy. structural knowledge is intrinsic to problem solving. because of the interdisciplinary nature of the healthcare domain and the broadness of the term, research is performed in several research fields, such as nursing, nursing informatics, long-term care, medical informatics, geriatrics, information technology, telecommunications, and so forth. although electronic journals enable searching by author, article, and journal title using keywords or full text, the results are limited to article content and references and therefore do not provide an in-depth understanding of the knowledge structure in a specific domain. the knowledge structure includes the core journals, core issues, the analysis of research trends, and the changes in focus of researchers. for a novice researcher, however, the literature survey remains a troublesome process in terms of precisely identifying the key articles that highlight the overview concept in a specific domain. the process is complicated and time-consuming, and it limits the number of articles collected for retrospective research. the objective of this paper is to provide information about the challenges and methodology of relevant literature retrieval by systematically reviewing the effectiveness of healthcare strategies. to this end, we build a platform for automatically gathering the full text of ejournals offered by the pubmed central (pmc) database.11 we then analyze the co-citation results to understand the research theme of the domain. methods this paper tries to build a value-added literature database system for co-citation analysis of healthcare research. the results of the analysis will be visually presented to provide the structure of the domain knowledge to increase the productivity of researchers. information technology and libraries | march 2018 41 dataset for co-citation analysis, a data source of related articles on healthcare is required. for this paper, the articles were retrieved from the pmc database using search terms related to the healthcare domain. to build the article analysis system, we used bibliometrics to locate the relevant references while analysis techniques were implemented by the association rule algorithm of data mining. the pmc database, which is produced by the us national institutes of health and is implemented and maintained by the us national center for biotechnology information of the us national library of medicine, provides electronic articles from more than one thousand full-text journals for free. we could understand the publication status from the open access subset (oas) and access to the oai (open archives initiative) protocol for metadata harvesting, which includes the full text in xml and pdf. regarding access permission, pmc offers a dataset of many open access journal articles. this paper used a dedicated xml-formatted dataset (https://www.ncbi.nlm.nih.gov/pmc/tools/oai/). the xml-formatted dataset followed the specification of dtd (document type definition) files, which are sorted by journal title. each article has a pmcid (pmc identification), which is useful for data analysis. in addition to the dataset, the pmc also provides several web services to help widely disseminate articles to researchers. pubmed central (pmc)

https://doi.org/10.6017/ital.v37i1.9595 system architecture our development environment consisted of the following four subsystems: front-end, middle-end, back-end, and pre-processing. the front-end creates a “web view,” a visualization of the results for our web-based co-citation analysis system. the system architecture is shown in figure 1. front-end development subsystem we used adobe dreamweaver cs5 as a visual development tool for the design of web templates. the php programming language was chosen to build the co-citation system that would be used to access and analyze the full-text articles. in terms of the data mining technique, we implemented the apriori algorithm with the php language.12 the results were exported as xml to a charting process, where we used amcharts (https://www.amcharts.com/), to create stock charts, column charts, pie charts, scatter charts, line charts, and so forth. middle-end server subsystem the system architecture was a microsoft windows-based environment with a xampp 2.5 web server platform (https://www.apachefriends.org/download.html). xampp is a cross-platform web development kit that consists of apache, mysql, php, and perl. it works across several operating systems, such as linux, windows, apache, macos, and oracle solaris, and provides ssl encryption, a phpmyadmin database management system, webalizer traffic management and control suite, a mail server (mercury mail transport system), and filezilla ftp server. back-end database subsystem to speed up co-citation analysis, the back-end database system used mysql 5.0.51b with interface phpmyadmin 2.11.7 for easy management of the database. mysql includes the following features: • using c and c++ to code programs, users can develop an application programming interface (api) through visual basic, c, c + +, eiffel, java, perl, php, python, ruby, and tcl languages with the multithreading capability that can be used in multi-cpu systems and easily linked to other databases. • performance of querying articles is quick because sql commands are optimally implemented, providing many additional commands and functions for a user-friendly and flexible operating database. an encryption mechanism is also offered to improve data confidentiality. • mysql can handle a large-scale dataset. the storage capacity is up to 2tb for win32 nts systems and up to 4tb for linux ext3 systems. • it provides the software myodbc as an odbc driver for connecting many programming languages, and it several languages and character sets to achieve localization and internationalization. pre-processing subsystem the pmc provides access to the article via oas, oai services, e-utilities, and ftp. we used ftp to download a compressed (zip) file packaged with a filename following the pattern “articles?-?.xml.tar.gz” on october 28, 2012 (ftp://ftp.ncbi.nlm.nih.gov/pub/pmc), where “?-?” is “0-9” or “a-z”. the size of the zip file was approximately 6.17gb. after extraction, the size of the articles was approximately 10gb. the 571,890 articles from 3,046 journals were grouped and https://www.amcharts.com/ https://www.apachefriends.org/download.html ftp://ftp.ncbi.nlm.nih.gov/pub/pmc information technology and libraries | march 2018 43 sorted by journal title in a folder labeled with an abbreviated title. an xml file would, for example, be named “aapsj-10-1-2751445.nxml,” where “aapsj” was the abbreviated title of the journal american association of pharmaceutical scientists journal, “10” was the volume of the journal, “1” was number of the issue, and “2751445” was the pmcid. we used related technologies for developing systems that include php language, array usage, and the apriori algorithm to analyze the articles and build the co-citation system.13 finally, several analysis modules were created to build an integrated co-citation system. research procedure the following is our seven-step research procedure to fulfill the integrated co-citation system: 1. parse xml file: select tags for construction of database; choose fields for co-citation analysis (for example, <journal-title>, <author-list>, and <reference-list>). 2. present web-based article: design webpage and css style; present web-based xml file by indexing variable <pmcid>. 3. build an abstract database: the database consists of several fields: <author-list>, <article-title>, <journal-title>, <volume>, <issue>, <pub-date>, and <abstract>. 4. develop searching module: pass the keyword to the method “post” in sql query language and present the search result in the webpage. 5. develop statistical module: the statistical results include number of article and cited articles, the journals and authors cited in all articles, and the number of cited articles. 6. develop citation module: visually present the statistical results in several formats; rank searched journals; rank searched and cited journals in all the articles. 7. develop co-citation module: analyze the association between articles with the apriori algorithm. association rule algorithms the association rule (ar), usually represented by ab, means that the transaction containing item a also contains item b. there are many such rules in most of the dataset, but some were useless. to validate the rules, two indicators, support and confidence, can be applied. support, which means usefulness, is the number of times the rules feature in the transactions, whereas confidence means certainty, which is the probability that b occurs whenever the a occurs. we chose the rules for which the values of both support and confidence were greater than a predefined threshold. for example, a rule stipulating “toastjam” has support of 1.2 percent and confidence of 65 percent, implying that 1.2 percent of the transactions contain “toast” and “jam” and that 65 percent of the transactions containing “toast” also contained “jam.” the principle for generating the ar is based on two features of the documents: (1) find the highfrequency items that set their supports greater than the threshold; (2) for each dataset x and its subnet y, check the rule xy if the support is greater than the threshold, in which the rule xy means that the occurrence in the rule containing x also contains y. most studies focus on searching high-frequency item sets.14 the most popular approach for identifying the item sets is apriori algorithm, as shown in figure 2.15 the algorithm rationale is that if the support of item set i is less identifying emerging issues in the healthcare domain | chu, lu, and liu 44 https://doi.org/10.6017/ital.v37i1.9595 than or equal to the threshold, i is not a high-frequency item set. new item set i that inserts any item a into i would not be a high-frequency item set. according to the rationale, the apriori algorithm is an iteration-based approach. first, it generates candidate item set c1 by calculating the number of occurrences of each attribute and finding that the high-frequency item set l1 has support greater than the threshold. second, it generates item set c2 by joining l1 to c1, iteratively finding l2 and generating c3, and so on. 1: l1 = {large 1-item sets}; 2: for (k=2; lk-1; k++) do begin 3: ck = candidate_gen (lk-1); 4: for all transactions td do begin /* generate candidate k-dataset*/ 5: ct = subset (ck, t); 6: for all candidates c  ct do 7: c_count=c_count+1; 8: end 9: lk ={cck | c_count ≥ minsuppport} 10: end 11: return l =  lk; figure 2. the apriori algorithm. the apriori algorithm is one of the most commonly used methods for ar induction. the candidate_gen algorithm, as shown in figure 3, includes join and prune operations for generating candidate sets.16 steps 1 to 4 generate all possible candidate item sets c from lk-1. steps 5 to 8: delete the item set that is not a frequent item set by the apriori algorithm. step 9 returns candidate set ck to the main algorithm. 1: for each item set x1 lk-1 2: for each item set x2 lk-1 3: c = join (x1[1], x1[2], x1[k-2], x1[k-1], x2[k-1]) 4: where x1[1] = x2[1], x1[k-2] = x2[k-2], x1[k-1] < x2[k-1]; 5: for item sets c  ck do 6: for all (k-1)-subsets s of c do 7: if (s  lk-1) then add c to ck; 8: else delete c from ck; 9: return ck; figure 3. the candidate_gen algorithm. information technology and libraries | march 2018 45 results we searched the pmc database with keywords “healthcare,” “telecare,” “ecare,” “ehealthcare,” and “telemedicine” and located 681 articles with a combined 14,368 references. values were missing from the year field for 4 of the references; this was also the case for 635 of a total of 52,902 authors. according to the keyword search for the healthcare domain, a pie chart of the journal citation analysis, as shown in figure 4, the top-ranked journal in terms of citations was the british medical journal (bmj). it was cited approximately 439 times, 18.89 percent of the total, followed by the journal of the american medical association (jama), which was cited approximately 344 times, 14.80 percent of the total. the trend of healthcare citation 1852 to 2009 peaked in 2006 at approximately 1,419 citations, with more than half of the total occurring in this year. figure 4. top-cited journals in the healthcare domain by percentage of total citations (n = 2324) with the keyword search for the healthcare domain, figure 5 shows a pie chart of the author citations. the most-cited author was j. w. varni, professor of pediatric cardiology at the university of michigan mott children’s hospital in ann arbor. this author was cited approximately 149 times, equivalent to 23.24 percent of the total, followed by d. n. herndon, professor at the department of plastic and hand surgery, friedrich-alexander university of erlangen in germany. this author was cited approximately 73 times, 11.39 percent of the total. by identifying the affiliations of the topranked authors, researchers can access related information in their field of interest. the co-citation analysis was conducted using the apriori algorithm. the relationship of co-citation journals with a supporting degree greater than 38 from 1852 to 2009 is shown in figure 6. each identifying emerging issues in the healthcare domain | chu, lu, and liu 46 https://doi.org/10.6017/ital.v37i1.9595 journal was denoted by a node, where the node with double circle meant the journal is co-cited with the other in a citing article. bmj, which covers the fields of evidence-based nursing care, obstetrics, healthcare, nursing knowledge and practices, and others, is the core journal of the healthcare domain. figure 5. top-cited authors in journals of the healthcare domain by percentage of total citations (n = 641) figure 6. the relationship of co-citation journals with bmj. information technology and libraries | march 2018 47 to identify the focus of the journal, we analyze the co-citation in three periods. in 1852–1907, journals are not in co-citation relationships; in 1908–61, five candidates had a supporting degree greater than 1 (see table 1); and in 1962–2009, twenty-eight candidates had a supporting degree greater than 14 (see table 2 (for example, bmj and lancet had sixty-eight co-citations). table 1. candidates in co-citation analysis with a supporting degree greater than 1 (1908–61). no journals no.

in the healthcare domain | chu, lu, and liu 50 https://doi.org/10.6017/ital.v37i1.9595 this paper presented an automated literature system for co-citation analysis to facilitate understanding of the sequence structure of journal articles cited in the healthcare domain. the system visually presents the results of its analysis to help researchers quickly identify the key articles that provide an overview of the healthcare domain. this paper used the keywords related to healthcare for its analysis and found that bmj is a core journal in the domain. the co-citation analysis found a single cluster within the healthcare domain comprising four journals: bmj, jama, lancet, and the new england journal of medicine. this paper focused on a co-citation analysis of journals. authors, articles, and issues featured in the co-citation analysis can be further studied in an automated way. a period analysis of publication years is also important. further analyses can facilitate understanding of the changes in a research domain and the trend of research issues. in addition, the automatic generation of a map would be a worthwhile topic for the future study. acknowledgements this article was

web services and widgets for library information systems | han 87on the clouds: a new way of computing | han 87 shape cloud computing. for example, sun’s well-known slogan “the network is the computer” was established in late 1980s. salesforce.com has been providing on-demand software as a service (saas) for customers since 1999. ibm and microsoft started to deliver web services in the early 2000s. microsoft’s azure service provides an operating system and a set of developer tools and services. google’s popular google docs software provides web-based word-processing, spreadsheet, and presentation applications. google app engine allows system developers to run their python/java applications on google’s infrastructure. sun provides $1 per cpu hour. amazon is well-known for providing web services such as ec2 and s3. yahoo! announced that it would use the apache hadoop framework to allow users to work with thousands of nodes and petabytes (1 million gigabytes) of data. these examples demonstrate that cloud computing providers are offering services on every level, from hardware (e.g., amazon and sun), to operating systems (e.g., google and microsoft), to software and service (e.g., google, microsoft, and yahoo!). cloud-computing providers target a variety of end users, from software developers to the general public. for additional information regarding cloud computing models, the university of california (uc) berkeley’s report provides a good comparison of these models by amazon, microsoft, and google.4 as cloud computing providers lower prices and it advancements remove technology barriers—such as virtualization and network bandwidth—cloud computing has moved into the mainstream.5 gartner stated, “organizations are switching from factors related to cloud computing: infinite computing resources available on demand, removing the need to plan ahead; the removal of an up-front costly investment, allowing companies to start small and increase resources when needed; and a system that is pay-for-use on a short-term basis and releases customers when needed (e.g., cpu by hour, storage by day).2 national institute of standards and technology (nist) currently defines cloud computing as “a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. network, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”3 as there are several definitions for “utility computing” and “cloud computing,” the author does not intend to suggest a better definition, but rather to list the characteristics of cloud computing. the term “cloud computing” means that ■■ customers do not own network resources, such as hardware, software, systems, or services; ■■ network resources are provided through remote data centers on a subscription basis; and ■■ network resources are delivered as services over the web. this article discusses using cloud computing on an it-infrastructure level, including building virtual server nodes and running a library’s essential computer systems in remote data centers by paying a fee instead of running them on-site. the article reviews current cloud computing services, presents the author’s experience, and discusses advantages and disadvantages of using the new approach. all kinds of clouds major it companies have spent billions of dollars since the 1990s to on the clouds: a new way of computing this article introduces cloud computing and discusses the author’s experience “on the clouds.” the author reviews cloud computing services and providers, then presents his experience of running multiple systems (e.g., integrated library systems, content management systems, and repository software). he evaluates costs, discusses advantages, and addresses some issues about cloud computing. cloud computing fundamentally changes the ways institutions and companies manage their computing needs. libraries can take advantage of cloud computing to start an it project with low cost, to manage computing resources cost-effectively, and to explore new computing possibilities. s cholarly communication and new ways of teaching provide an opportunity for academic institutions to collaborate on providing access to scholarly materials and research data. there is a growing need to handle large amounts of data using computer algorithms that presents challenges to libraries with limited experience in handling nontextual materials. because of the current economic crisis, academic institutions need to find ways to acquire and manage computing resources in a cost-effective manner. one of the hottest topics in it is cloud computing. cloud computing is not new to many of us because we have been using some of its services, such as google docs, for years. in his latest book, the big switch: rewiring the world, from edison to google, carr argues that computing will go the way of electricity: purchase when needed, which he calls “utility computing.” his examples include amazon’s ec2 (elastic computing cloud), and s3 (simple storage) services.1 amazon’s chief technology officer proposed the following yan hantutorial yan han (hany@u.library.arizona.edu) is associate librarian, university of arizona libraries, tucson. 88 information technology and libraries | june 201088 information technology and libraries | june 2010 company-owner hardware and software to per-use service-based models.”6 for example, the u.s. government website (http://www.usa .gov/) will soon begin using cloud computing.7 the new york times used amazon’s ec2 and s3 services as well as a hadoop application to provide open access to public domain articles from 1851 to 1922. the times loaded 4 tb of raw tiff images and their derivative 11 million pdfs into amazon’s s3 in twenty-four hours at very reasonable cost.8 this project is very similar to digital library projects run by academic libraries. oclc announced its movement of library management services to the web.9 it is clear that oclc is going to deliver a web-based integrated library system (ils) to provide a new way of running an ils. duraspace, a joint organization by fedora commons and dspace foundation, announced that they would be taking advantage of cloud storage and cloud computing.10 on the clouds computing needs in academic libraries can be placed into two categories: user computing needs and library goals. user computing needs academic libraries usually run hundreds of pcs for students and staff to fulfill their individual needs (e.g., microsoft office, browsers, and image-, audio-, and video-processing applications). library goals a variety of library systems are used to achieve libraries’ goals to support research, learning, and teaching. these systems include the following: ■■ library website: the website may be built on simple html webpages or a content management system such as drupal, joomla, or any home-grown php, perl, asp, or jsp system. ■■ ils: this system provides traditional core library work such as cataloging, acquisition, reporting, accounting, and user management. typical systems include innovative interfaces, sirsidynix, voyager, and opensource software such as koha. ■■ repository system: this system provides submission and access to the institution’s digital collections and scholarship. typical systems include dspace, fedora, eprints, contentdm, and greenstone. ■■ other systems: for example, federated search systems, learning object management systems, interlibrary loan (ill) systems, and reference tracking systems. ■■ public and private storage: staff file-sharing, digitization, and backup. due to differences in end users and functionality, most systems do not use computing resources equally. for example, the ils is input and output intensive and database query intensive, while repository systems require storage ranging from a few gigabytes to dozens of terabytes and substantial network bandwidth. cloud computing brings a fundamental shift in computing. it changes the way organizations acquire, configure, manage, and maintain computing resources to achieve their business goals. the availability of cloud computing providers allows organizations to focus on their business and leave general computing maintenance to the major it companies. in the fall of 2008, the author started to research cloud computing providers and how he could implement cloud computing for some library systems to save staff and equipment costs. in january 2009, the author started his plan to build library systems “on the clouds.” the university of arizona libraries (ual) has been a key player in the process of rebuilding higher education in afghanistan since 2001. ual librarian atifa rawan and the author have received multiple grant contracts to build technical infrastructures for afghanistan’s academic libraries. the technical infrastructure includes the following: ■■ afghanistan ils: a bilingual ils based on the open-source system koha.11 ■■ afghanistan digital libraries website (http://www.afghan digitallibraries.org/): originally built on simple html pages, later rebuilt in 2008 using the content management system joomla. ■■ a digitization management system. the author has also developed a japanese ill system (http://gif project.libraryfinder.org) for the north american coordinating council on japanese library resources. these systems had been running on ual’s internal technical infrastructure. these systems run in a complex computing environment, require different modules, and do not use computing resources equally. for example, the afghan ils runs on linux, apache, mysql, and perl. its opac and staff interface run on two different ports. the afghanistan digital libraries website requires linux, apache, mysql, and php. the japanese ill system was written in java and runs on tomcat. there are several reasons why the author moved these systems to the new cloud computing infrastructure: ■■ these systems need to be accessed in a system mode by people who are not ual employees. ■■ system rebooting time can be substantial in this infrastructure because of server setup and it policy. ■■ the current on-site server has web services and widgets for library information systems | han 89on the clouds: a new way of computing | han 89 reached its life expectancy and requires a replacement. by analyzing the complex needs of different systems and considering how to use resources more effectively, the author decided to run all the systems through one cloud computing provider. by comparing the features and the costs, linode (http://www.linode.com/) was chosen because it provides full ssh and root access using virtualization, four data centers in geographically diverse areas, high availability and clustering support, and an option for month-to-month contracts. in addition, other customers have provided positive reviews. in january 2009, the author purchased one node located in fremont, california, for $19.95 per month. an implementation plan (see appendix) was drafted to complete the project in phases. the author owns a virtual server and has access to everything that a physical server provides. in addition, the provider and the user community provided timely help and technical support. the migration of systems was straightforward: a linux kernel (debian 4.0) was installed within an hour, domain registration was complete and the domains went active in twenty-four hours, the afghanistan digital libraries’ website (based on joomla) migration was complete within a week, and all supporting tools and libraries (e.g., mysql, tomcat, and java sdk) were installed and configured within a few days. a month later, the afghanistan ils (based on koha) migration was completed. the ill system was also migrated without problem. tests have been performed in all these systems to verify their usability. in summary, the migration of systems was very successful and did not encounter any barriers. it addresses the issues facing us: after the migration, ssh log-ins for users who are not university employees were set up quickly; systems maintenance is managed by the author’s team, and rebooting now only takes about one minute; and there is no need to buy a new server and put it in a temperature and security controlled environment. the hardware is maintained by the provider. the administrative gui for the linux nodes is shown in figure 1. since migration, no downtime because of hardware or other failures caused by the provider has been observed. after migrating all the systems successfully and running them in a reliable mode for a few months, the second phase was implemented (see appendix). another linux node (located in atalanta, georgia) was purchased for backup and monitoring (see figure 2). nagios, an open-source monitoring system, was tested and configured to identify and report problems for the above library systems. nagios provides the following functions: (1) monitoring critical computing components, such as the network, systems, services, and servers; (2) timely alerts delivered via e-mail or cell phone; and (3) report and record logs of outages, events, and alerts. a backup script is also run as a prescheduled job to back up the systems on a regular basis. figure 1. linux node administration web interface figure 2. two linux nodes located in two remote data centers node 1: 64.62.xxx.xxx

information technology and libraries | june 2010 findings and discussions since january 2009, all the systems have been migrated and have been running without any issues caused by the provider. the author is very satisfied with the outcomes and cost. the annual cost of running two nodes is $480 per year, compared to at least $4,000 dollars if the hardware had been run in the library.12 from the author ’s experience, cloud computing provides the following advantages over the traditional way of computing in academic institutions: ■■ cost-effectiveness: from the above example and literature review, it is obvious that using cloud computing to run applications, systems, and it infrastructure saves staff and financial resources. uc berkeley’s report and zawodny’s blog provide a detailed analysis of costs for cpu hours and disk storage.13 ■■ flexibility: cloud computing allows organizations to start a project quickly without worrying about up-front costs. computing resources such as disk storage, cpu, and ram can be added when needed. in this case, the author started on a small scale by purchasing one node and added additional resources later. ■■ data safety: organizations are able to purchase storage in data centers located thousands of miles away, increasing data safety in case of natural disasters or other factors. this strategy is very difficult to achieve in a traditional off-site backup. ■■ high availability: cloud computing providers such as microsoft, google, and amazon have better resources to provide more up-time than almost any other organizations and companies do. ■■ the ability to handle large amounts of data: cloud computing has a pay-for-use business model that allows academic institutions to analyze terabytes of data using distributed computing over hundreds of computers for a short-time cost. on-demand data storage, high availability and data safety are critical features for academic libraries.14 however, readers should be aware of some technical and business issues: ■■ availability of a service: in several widely reported cases, amazon’s s3 and google gmail were inaccessible for a duration of several hours in 2008. the author believes that the commercial providers have better technical and financial resources to keep more up-time than most academic institutions. for those wanting no single point of failure (e.g., a provider goes out of business), the author suggests storing duplicate data with a different provider or locally. ■■ data confidentiality: most academic libraries have open-access data. this issue can be solved by encrypting data before moving to the clouds. in addition, licensing terms can be negotiated with providers regarding data safety and confidentiality. ■■ data transfer bottlenecks: accessing the digital collections requires considerable network bandwidth, and digital collections are usually optimized for customer access. moving huge amounts of data (e.g., preservation digital images, audios, videos, and data sets) to data centers can be scheduled during off hours (e.g., 1–5 a.m.), or data can be shipped on hard disks to the data centers. ■■ legal jurisdiction: legal jurisdiction creates complex issues for both providers and end users. for example, canadian privacy laws regulate data privacy in public and private sectors. in 2008, the office of the privacy commissioner of canada released a finding that “outsourcing of canada .com email services to u.s.-based firm raises questions for subscribers,” and expressed concerns about public sector privacy protection.15 this brings concerns to both providers and end users, and it was suggested that privacy issues will be very challenging.16 summary the author introduces cloud computing services and providers, presents his experience of running multiple systems such as ils, content management systems, repository software, and the other system “on the clouds” since january 2009. using cloud computing brings significant cost savings and flexibility. however, readers should be aware of technical and business issues. the author is very satisfied with his experience of moving library systems to cloud computing. his experience demonstrates a new way of managing critical computing resources in an academic library setting. the next steps include using cloud computing to meet digital collections’ storage needs. cloud computing brings fundamental changes to organizations managing their computing needs. as major organizations in library fields, such as oclc, started to take advantage of cloud computing, the author believes that cloud computing will play an important role in library it. acknowledgments the author thanks usaid and washington state university for providing

siew-phek t;needamangala, ashwin information technology and libraries; mar 2000; 19, 1; proquest pg. 17 harvesting information from a library data warehouse data warehousing technology has been defined by john ladley as "a set of methods, techniques, and tools that are leveraged together and used to produce a vehicle that delivers data to end users on an integrated platform. "1 this concept has been applied increasingly by industries worldwide to develop data warehouses for decision support and knowledge discovery. in the academic sector, several universities have developed data warehouses containing the universities'ftnancial, payroll, personnel, budget, and student data.2 these data warehouses across all industries and academia have met with varying degrees of success. data warehousing technology and its related issues have been widely discussed and published. 3 little has been done, however, on the application of this cutting edge technology in the library environment using library data. i motivation of project daniel boorstin, the former librarian of congress, mentions that "for most of western history, interpretation has far outrun data." 4 however, he points out "that modem tendency is quite the contrary, as we see data outrun meaning." his insights tie directly to many large organizations that long have been rich in data but poor in information and knowledge. library managers are increasingly finding the importance of obtaining a comprehensive and integrated view of the library operations and the services it provides. this view is helpful for the purpose of making decisions on the current operations and for their improvement. due to financial and human constraints for library support, library managers increasingly encounter the need to justify everything they dofor example, the library's operation budget. the most frustrating problem they face is knowing that the information needed is available somewhere in the ocean of data but there is no easy way to obtain it. for example, it is not easy to ascertain whether the materials of a certain subject area, which consumed a lot of financial resources for their acquisition and processing, are either frequently used (i.e., high rate of circulation), seldom used, or not used at all. or, whether they satisfy users' needs. another example, an analysis of the methods of acquisition (firm order vs. approval plan) together with the circulation rate could be used as a factor in deciding the best method of acquiring certain types of material. such information can play a pivotal role in performing collection development and library management more efficiently and effectively. unfortunately, the data needed to make these types of decisions are often scattered in different files maintained siew-phek t. su and ashwin needamangala by a large centralized system, such as notis, that does not provide a general querying facility or by different file/ data management or application systems. this situation makes it very difficult and time-consuming to extract useful information. this is precisely where data warehousing technology comes in. the goal of this research and development work is to apply data warehousing and data mining technologies in the development of a library decision support system (loss) to aid the library management's decision making. the first phase of this work is to establish a data warehouse by importing selected data from separately maintained files presently used in the george a. smathers libraries of the university of florida into a relational database system (microsoft access). data stored in the existing files were extracted, cleansed, aggregated, and transformed into the relational representation suitable for processing by the relational database management system. a graphical user interface (gui) is developed to allow decision makers to query for the data warehouse's contents using either some predefined queries or ad hoc queries. the second phase is to apply data mining techniques on the library data warehouse for knowledge discovery. this paper covers the first phase of this research and development work. our goal is to develop a general methodology and inexpensive software tools, which can be used by different functional units of a library to import data from different data sources and to tailor different warehouses to meet their local decision needs. for meeting this objective, we do not have to use a very large centralized database management system to establish a single very large data warehouse to support different uses. i local environment the university of florida libraries has a collection of more than two million titles, comprising over three million volumes. it shares a notis-based integrated system with nine other state university system (sus) libraries for acquiring, processing, circulating, and accessing its collection. all ten sus libraries are under the consortium umbrella of the florida center for library automation (fcla). siew-phekt. su (pheksu@mail.uflib.ufl.edu) is associate chair of the central bibliographic services section, resource services department, university of florida libraries, and ashwin needamangala (nsashwin@grove.ufl.edu) is a graduate student at the electrical and computer engineering department, university of florida. harvesting information from a library data warehouse i su and needamangala 17 reproduced with permission of the copyright owner. further reproduction prohibited without permission. i library data sources the university of florida libraries' online database, luis, stores a wealth of data, such as bibliographic data (author, title, subject, publisher information), acquisitions data (price, order information, fund assignment), circulation data (charge out and browse information, withdrawn and inventory information), and owning location data (where item is shelved). these voluminous data are stored in separate files. the notis system as used by the university of florida does not provide a general querying facility for accessing data across different files. extracting any information needed by a decision maker has to be done by writing an application program to access and manipulate these files. this is a tedious task since many application programs would have to be written to meet the different information needs. the challenge of this project is to develop a general methodology and tools for extracting useful data and metadata from these disjointed files, and to bring them into a warehouse that is maintained by a database management system such as microsoft access. the selection of access and pc hardware for this project is motivated by cost consideration. we envision that multiple special purpose warehouses be established on multiple pc systems to provide decision support to different library units. the library decision support system (loss) is developed with the capability of handling and analyzing an established data warehouse. for testing our methodology and software system, we established a warehouse based on twenty thousand monograph titles acquired from our major monograph vendor. these titles were published by domestic u.s. publishers and have a high percentage of dlc/dlc records (titles cataloged by the library of congress). they were acquired by firm order and approval plan, the publication coverage is the calendar year 1996-1997. analysis is only on the first item record (future project will include all copy holdings). although the size of the test data used is small, it is sufficient to test our general methodology and the functionality of our software system. fcla d82 tables and key list most of the data from the twenty-thousand-title domain that go into the loss warehouse are obtained from the db2 tables maintained by fcla. fcla developed and maintains the database of a system called ad hoc report request over the web (arrow) to facilitate querying and generating reports on acquisitions activities . the data are stored in 0b2 tables. 5 for our research and development purpose, we needed db2 tables for only the twenty-thousand titles that we identified as our initial project domain. these titles all have an identifiable 035 field in the bibliographic records (zybp1996, zybcip1996, zybp1997 or zybpcip1997). we used the batchbam program developed by gary strawn of northwestern university library to extract and list the unique bibliographic record numbers in separate files for fcla to pick up. 6 using the unique bibliographic record numbers, fcla extracted the 0b2 tables from the arrow database and exported the data to text files. these text files then were transferred to our system using the file transfer protocol (frp) and inserted as tables into the loss warehouse. bibliographic and item records extraction fcla collects and stores complete acquisitions data from the order records as db2 tables. however, only brief bibliographic data and no item record data are available . bibliographic and item record data are essential for inclusion in the loss warehouse in order to create a viable integrated system capable of performing cross-file analysis and querying for the relationships among different types of data. because these required data do not exist in any computer readable form, we designed a method to obtain them. using the identical notis key lists to extract the targeted twenty-thousand bibliographic and item records, we applied a screen scraping technique to scrape the data from the screen and saved them in a flat file. we then wrote a program in microsoft visual basic to clean the scraped data and saved them as text-delimited files that are suitable for importing into the loss warehouse. screen scraping concept screen scraping is a process used to capture data from a host application. it is conventionally a three-part process: • displaying the host screen or data to be scraped. • finding the data to be captured. • capturing the data to a pc or host file, or using it in another windows application. in other words, we can capture particular data on the screen by providing the corresponding screen coordinates to the screen scraping program. numerous commercial applications for screen scraping are available on the market. however, we used an approach slightly different from the conventional one. although we had to capture only certain fields from the notis screen, there were other factors that we had to take into consideration. they are: • the location of the various fields with respect to the screen coordinates changes from record to record . this makes it impossible for us to lock a particular field with a corresponding screen coordinate. 18 information technology and libraries i march 2000 reproduced with permission of the copyright owner. further reproduction prohibited without permission. • the data present on the screen are dynamic because we are working on a "live" database where data are frequently modified. for accurate query results, all the data, especially the item record data where the circulation transactions are housed, need to be captured within a specified time interval so that the data are uniform. this makes the time taken for capturing the data extremely important. • most of the fields present on the screen needed to be captured. taking the above factors into consideration, it was decided to capture the entire screen instead of scraping only certain parts of the screen. this made the process both simpler and faster . the unnecessary fields were filtered out during the cleanup process . i system architecture the architecture of the loss system is shown in figure 1 and is followed by a discussion on its components' functions. notis notis (northwestern online totally integrated system) was developed at the northwestern university library and introduced in 1970. since its inception, notis has undergone many versions. university of florida libraries is one of the earliest users of notis. fcla has made many local modifications of the notis system since uf libraries started using it. as a result, the uf notis is different from the rest of the notis world in many respects . notis can be broken down into four subsystems: • acquisitions • cataloging • circulation • online public access catalog (opac) at the university of florida libraries, the notis system runs on an ibm 370 main frame computer that runs the os/390 operating system . host explorer host explorer is a software program that provides a tcp /ip link to the main frame computer . it is a terminal emulation program supporting the ibm main frame, as/400, and vax hosts . host explorer delivers an enhanced user environment for all windows nt platforms, windows 95 and windows 3.x desktops. exact tn3270e, tn5250, vt420/320/220/101/100/52, wyse 50/60 and ansi-bbs display is extended to leverage the wealth of the windows desktop. it also supports all db2tables loss host explorer data cleansing and extraction warehouse graphical user interface figure 1. loss architecture and its components tcp /ip based tn3270 and tn3270e gateways. the host explorer program is used as the terminal emulation program in loss. it also provides vba compatible basic scripting tools for complete desktop macro development. users can run these macros directly or attach them to keyboard keys, toolbar buttons, and screen hotspots for additional productivity. the function of host explorer in the loss is v ery simple. it has to "visit" all screens in the notis system corresponding to each notis number present in the batchbam file, and capture all the data on the screens. in order to do this, we wrote a macro that read the notis number one at a time from the batchbam file and input the number into the command string of host explorer . the macro essentially performed the following functions: • read the notis numbers from the batchbam file. • inserted the notis number into the command string of host explorer . • toggled the screen capture option in host explorer so that data are scraped from the screen only at necessary times. • saved all the scraped data into a flat file. after the macro has been executed, all the data scraped from the notis screen reside in a flat file. the data present harvesting information from a library data warehouse i su and needamangala 19 reproduced with permission of the copyright owner. further reproduction prohibited without permission. in this file have to be cleansed in order to make them suitable for insertion into the library warehouse. a visual basic program is written to perform this function. the details of this program will be given in the next section. i data cleansing and extraction this component of the loss is written in the visual basic programming language. its main function is to cleanse the data that have been scraped from the notis screen. the visual basic code saves the cleansed data in a text-delimited format that is recognized by microsoft access. this file is then imported into the library warehouse maintained by microsoft access. the detailed working of the code that performs the cleansing operation is discussed below. the notis screen that comes up for each notis number has several parts that are critical to the working of the code. they are: • notis number present in the top-right of the screen (in this case, akr9234) • field numbers that have to be extracted. example: 010::, 035:: • delimiters. the " i " symbol is used as the delimiter throughout this code. for example, in the 260 field of a bibliographic record, "i a" delimits the place of publication, " i b" the name of the publisher and, "i c" the date of publication. we shall now go step by step through the cleansing process. initially we have the flat file containing all the data that have been scraped from the notis screens. • the entire list of notis numbers from the batchbam file is read into an array called bam_number$. • the file containing the data that have been scraped is read into a single string called bibrecord$. • this string is then parsed using the notis numbers from the bam_number$ array. • we now have a string that contains a single notis record. this string is called single_record$. • the program runs in a loop till all the records have been read. • each string is now broken down into several smaller strings based on the field numbers. each of these smaller strings contains data pertaining to the corresponding field number. • a considerable amount of the data present on the notis screen is unnecessary from the point of view of our project. we need only certain fields from the notis screen. but even from these fields we need the data only from certain delimiters. therefore, we now scan each of these smaller strings for a certain set of delimiters, which was predefined for each individual field. the data present in the other delimiters are discarded. • the data collected from the various fields and their corresponding delimiters are assigned to corresponding variables. some variables contain data from more than one delimiter concatenated together. the reason for this can be explained as follows. there are certain fields, which are present in the database only for informational purposes and will not be used as a criteria field in any query. since these fields will never be queried upon, they do not need to be cleansed as rigorously as the other fields and therefore, we can afford to leave the data of these fields as concatenated strings. example: the catalog_source field which has data from " i a" and " i c" is of the form " i a dlc i c dlc" while the lang code field which has data from "i a" and" i h" is of the form" i a eng i h rus." but we split this into two fields: lang_code_l containing "eng" and lang_code_2 containing "rus." • the data collected from the various fields are saved in a flat file in the text-delimited format. microsoft access recognizes this format. a screen dump of the text-delimited file, which is the end result of the cleansing operation, is shown in figure 2. the flat file, which we now have, can be imported into the library warehouse. i graphical user interface in order to ease the tasks of the user (i.e., the decision maker) to create the library warehouse and to query and analyze its contents, a graphical user interface tool has been developed. through the gui, the user can enact the following processes or operations through a main menu: • connection to notis • screen scraping • data cleansing and extracting • importing data • viewing collected data • querying • report generating the first option opens hostexplorer and provides a connection to notis. lt provides a shortcut to closing or minimizing ldss and opening hostexplorer. the screen scraping option activates the data scraping process. the data cleansing and extracting option filters out the unnecessary data fields and saves the cleansed data in a text-delimited format. the importing data option imports the data in the text-delimited format into the warehouse. the viewing collected data option allows the user to view the contents of a selected relational table stored in 20 information technology and libraries i march 2000 reproduced with permission of the copyright owner. further

in the warehouse. many data mining tools are now available in the commercial world. for our project, we are investigating the use of a neural-network-based data mining tool developed by limin fu of the university of florida.? the tool allows the discovery of association rules based on a set of training data provided to the tool. this part of our research and development work is still in progress . the existing gui and report generation facilities will be expanded to include the use of this mining tool. i library warehouse fcla exports the data existing in the 0b2 tables into text files. as a first step towards creating the database, these text files are transferred using ftp and form separate relational tables in the library warehouse. the data that harvesting information from a library data warehouse i su and needamangala 21 reproduced with permission of the copyright owner. further reproduction prohibited without permission. are scraped from the bibliographic and item record screens result in the formation of two more tables. characteristics data in the warehouse are snapshots of the original data files. only a subset of the data contents in these files are extracted for querying and analysis since not all the data are useful for a particular decision-making situation. data are filtered as they pass from the operational environment to the data warehouse environment. this filtering process is necessary particularly when a pc system, which has limited secondary storage and main memory space, is used. once extracted and stored in the warehouse, data are not updateable. they form a read-only database. however, different snapshots of the original files can be imported into the warehouse for querying and analysis. the results of the analyses of different snapshots can then be compared. structure data warehouses have a distinct structure. there are summarization and detail structures that demarcate a data warehouse. the structure of the library data warehouse is shown in figure 3. the different components of the library data warehouse as shown in figure 3 are: • notis and 0b2 tables. bibliographic and circulation data are obtained from notis through the screen scraping process and imported into the warehouse. fcla maintains acquisitions data in the form of db2 tables. these are also imported into the warehouse after conversion to a suitable format. • warehouse. the warehouse consists of several relational tables that are connected by means of relationships. the universal relation approach could have been used to implement the warehouse by using a single table. the argument for using the universal relation approach would be that all the collected data fall under the same domain. but let us examine why this approach would not have been suitable. the different data collected for import into the warehouse were bibliographic data, circulation data, order data, and pay data. now, if all these data were incorporated into one single table with many attributes, it would not be of any exceptional use since each set of attributes have their own unique meaning when grouped together as bibliographic table, circulation table, and so on. for example, if we group the circulation data and the pay data together in a single table, it would not make sense. however, the pay data and the circulation data are related through the bib_key. hence, our use of the conventional approach of havuser .....--------~----.----------......----=--___ bibliographic data view circulation data view ufbib, ufpay, ufinv, ufcirc, uford warehouse pay data view import screen scraping notis fcla db2 tables figure 3. structure of the library data warehouse ing several tables connected by means of relationships is more appropriate. • views. a view in sql terminology is a single table that is derived from other tables. these other tables could be base tables or previously defined views. a view does not necessarily exist in physical form; it is considered a virtual table, in contrast to base tables whose tables are actually stored in the database. in the context of the ldss, views can be implemented by means of the adhoc query wizard. the user can define a query /view using the wizard and save it for future use. the user can then define a query on this query i view. • summarization. the process of implementing views falls under the process of summarization. summarization provides the user with views, which make it easier for users to query on the data of their interests. as explained above, the specific warehouse we established consists of five tables. table names including "_wh" indicates that it contains current detailed data of the warehouse. current detailed data represents the most recent snapshot of data that has been taken from the notis system. the summarized views are derived from the current detailed data of the warehouse. since current detailed data of the warehouse are the basic data of the 22 information technology and libraries i march 2000 reproduced with permission of the copyright owner. further reproduction prohibited without permission. application, only the current detailed data tables are shown in appendix a. i decision support by querying the warehouse the warehouse contains a set of integrated relational tables whose contents are linked by the common primary key, the bib_key (biblio_key). the data stored across these tables can be traver sed by matching the key values associated with their tuples or records . decision makers can issue all sorts of sql-type queries to retrieve useful information from the warehouse. two general types of queries can be distinguished : predefined queries and ad hoc queries . the former type refers to queries that are frequently used by decision makers for accessing information from different snapshots of data imported into the warehouse . the latter type refers to queries that are exploratory in nature. a decision maker suspects that there is some relationship between different types of data and issues a query to verify the existence of such a relationship. alternatively, data mining tools can be applied to analyze the data contents of the warehouse and discover rules of their relationships (or associations). predefined queries below are some sample queries posted in english. their corresponding sql queries can be processed using loss. l. number and percentage of approval titles circulated and noncirculated. 2. number and percentage of firm order titles circulated and noncirculated . 3. amount of financial resources spent on acquiring noncirculated titles. 4. number and percentage of dlc/dlc cataloging records in circulated and noncirculated titles . 5. number and percentage of "shared" cataloging records in circulated and noncirculated titles. 6. numbers of original and "shared" cataloging records of noncirculated titles. 7. identify the broad subject areas of circulated and noncirculated titles . 8. identify titles that have been circulated "n" number of times and by subjects . 9. number of circulated titles without the 505 field. each of the above english queries can be realized by a number of sql queries. we shall use the first two english queries and their corresponding sql queries to explain how the data warehouse contents and the querying facility of microsoft access can be used to support decision making. the results of sql queries also are given . the first english query can be divided into two parts (see figure 4), each realized by a number of sql queries as shown below . sample query outputs query 1: number and percentage of approval titles circulated and noncirculated result : total approval titles circulated noncirculated 1172 980 192 83.76 % 16.24 % similar to the above sql queries, we can translate the second english query into a number of sql queries and the result is given below: query 2: number and percentage of firm order titles circulated and noncirculated result : total firm order titles circulated noncirculated report generation 1829 1302 527 71.18 % 28.82 % the results of the two predefined english queries can be presented to users in the form of a report. total titles 3001 approval 1172 39% circulated 980 83.76 % noncirculated 192 16.24 % firm order 1829 61% circulated 1302 71.18 % noncirculated 527 28 .82 % from the above report, we can ascertain that, though 39 percent of the titles were purchased through the approval plan and 61 percent through firm orders, the approval titles have a higher rate of circulation, 83.76 percent, as compared to firm order titles of 71.18 percent. it is important to note that the result of the above queries is taken from only one snapshot of the circulation data. analysis from several

technology and libraries | september 2016 9 abstract as the new generation of discovery systems evolve and gain maturity, it is important to continually focus on how users interact with these tools and what areas they find problematic. this study looks at user interactions within searchworks, a discovery system developed by stanford university libraries, with an emphasis on identifying and analyzing problematic and failed searches. our findings indicate that users still experience difficulties conducting author and subject searches, could benefit from enhanced support for browsing, and expect their overall search experience to be more closely aligned with that on popular web destinations. the article also offers practical recommendations pertaining to metadata, functionality, and scope of the search system that could help address some of the most common problems encountered by the users. introduction in recent years, rapid modernization of online catalogs has brought library discovery to the forefront of research efforts in the library community, giving libraries an opportunity to take a fresh look at such important issues as the scope of the library catalog, metadata creation practices, and the future of library discovery in general. while there is an abundance of studies looking at various aspects of planning, implementation, use, and acceptance of these new discovery environments, surprisingly little research focuses specifically on user failure. the present study aims to address this gap by identifying and analyzing potentially problematic or failed searches. it is hoped that focusing on common error patterns will help us gain a better understanding of users’ mental models, needs, and expectations that should be considered when designing discovery systems, creating metadata, and interacting with library patrons. terminology in this paper, we adopt a broad definition of discovery products as “tools and interfaces that a library implements to provide patrons the ability to search its collections and gain access to materials.”1 these products can be further subdivided into the following categories: irina trapido (itrapido@stanford.edu) is electronic resources librarian at stanford university libraries, stanford, california. mailto:itrapido@stanford.edu library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 10 • online catalogs (opacs)—patron-facing modules of an integrated library system. • discovery layers (also referred to as “discovery interfaces” or “next-generation library catalogs”)—new catalog interfaces, decoupled from the integrated library system and offering enhanced functionality, such as faceted navigation, relevance-ranked results, as well as the ability to incorporate content from institutional repositories and digital libraries. • web-scale discovery tools, which in addition to providing all interface features and functionality of next generation catalogs, broaden the scope of discovery by systematically aggregating content from library catalogs, subscription databases, and institutional digital repositories into a central index. literature review to identify and investigate problems that end users experience in the course of their regular searching activities, we analyzed digital traces of user interactions with the system recorded in the system’s log files. this method, commonly referred to as transaction log analysis, has been a popular way of studying information-seeking in a digital environment since the first online search systems came into existence, allowing researchers to monitor system use and gain insight into the users’ search process. server logs have been used extensively to examine user interactions with web search engines, consistently showing that web searchers tend to engage in short search sessions, enter brief search statements, do not browse the results beyond the first page, and rarely resort to advanced searching.2 a similar picture has emerged from transaction log studies of library catalogs. researchers have found that library users employ the same surface strategies: queries within library discovery tools are equally short and simply constructed; 3 the majority of search sessions consist of only one or two actions.4 patrons commonly accept the system’s default search settings and rarely take advantage of a rich set of search features traditionally offered by online catalogs, such as boolean searching, index browsing, term truncation, and fielded searching.5 although advanced searching in library discovery layers is uncommon, faceted navigation, a new feature introduced into library catalogs in the mid-2000s, quickly became an integral part of the users’ search process. research has shown that facets in library discovery interfaces are used both in conjunction with text searching, as a search refinement tool, and as a way to browse the collection with no search term entered.6 a recent study that analyzed interaction patterns in a faceted library interface at the north carolina state university using log data and user experiments demonstrated that users of faceted interfaces tend to issue shorter queries, go through fewer iterations of query reformulation, and scan deeper along the result list than those who use nonfaceted search systems. the authors also concluded that facets increase search accuracy, especially for complex and open-ended tasks, and improve user satisfaction.7 information technology and libraries | september 2016 11 another traditional use of transaction logs has been to gauge the performance of library catalogs, mostly through measuring success and failure rates. while the exact percentage of failed searches varied dramatically depending on the system’s search capabilities, interface design, the size of the underlying database, and, most importantly, on the researchers’ definition of an unsuccessful search, the conclusion was the same: the incidence of failure in library opacs was extremely high.8 in addition to reporting error rates, these studies also looked at the distribution of errors by search type (title, author, or subject search) and categorized sources of searching failure. most researchers agreed that typing errors and misspellings accounted for a significant portion of failed searches and were common across all search types.9 subject searching, which remained the most problematic area, often failed because of a mismatch between the search terms chosen by the user and the controlled vocabulary contained in the library records, suggesting that users experienced considerable difficulties in formulating subject queries with library of congress subject headings.10 other errors reported by researchers, such as the selection of the wrong search index or the inclusion of the initial article for title searches, were also caused by users’ lack of conceptual understanding of the search process and the system’s functions.11 these research findings were reinforced by multiple observational studies and user interviews, which showed that patrons found library catalogs “illogical,” “counter-intuitive,” and “intimidating,”12 and that patrons were unwilling to learn the intricacies of catalog searching.13 instead, users expected simple, fast, and easy searching across the entire range of library collections, relevance-ranked results that exactly matched what users expected to find, and convenient and seamless transition from discovery to access.14 today’s library discovery systems have come a long way: they offer one-stop search for a wide array of library resources, intuitive interfaces that require minimal training to be searched effectively, facets to help users narrow down the result set, and much more.15 but are today’s patrons always successful in their searches? usability studies of next-generation catalogs and, more recently, of web-scale discovery systems have pointed to patron difficulties associated with the use of certain facets, mostly because of terminological issues and inconsistencies in the underlying metadata.16 researchers also reported that users had trouble interpreting and evaluating the results of their search;17 users also were confused as to what resources were covered by the search tool.18 our study builds on this line of research by systematically analyzing real-life problematic searches as reported by library users and recorded in transaction logs. background stanford university is a private, four-year or above research university offering undergraduate and graduate degrees in a wide range of disciplines to about sixteen thousand students. the study analyzed the use of searchworks, a discovery platform developed by stanford university libraries. searchworks features a single search box with a link to advanced search on every page, relevanceranked results, faceted navigation, enhanced textual and visual content (summaries, tables of library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 12 content, book cover images, etc.), as well as “browse shelf” functionality. searchworks offers searching and browsing of catalog records and digital repository objects in a single interface; however, it does not allow article-level searching. searchworks was developed on the basis of blacklight (projectblacklight.org), an open-source application for searching and interacting with collections of digital objects.19 thanks to blacklight’s flexibility and extensibility, searchworks enables discovery across an increasingly diverse range of collections (marc catalog records, archival materials, sound recordings, images, geospatial data, etc.) and allows to continuously add new features and improvements (e.g., https://library.stanford.edu/blogs/stanford-libraries-blog/2014/09/searchworks-30-released). study objectives the goal of the present study was two-fold. first, we sought to determine how patrons interact with the discovery systems, which features they use and with what frequency. second, this study aimed to identify and analyze problems that users encounter in their search process. method this study used data comprising four years of searchworks use, which was recorded in apache solr logs. the analysis was performed at the aggregate level; no attempts were made to identify individual searchers from the logs. at the preprocessing stage, we created and used a series of perl scripts to clean and parse the data and extract only those transactions where the user entered a search query and/or selected at least one facet value. page views of individual records were excluded from the analysis. the resulting output file contained the following parameters for each transaction: a time stamp, search mode used (basic or advanced), query terms, search index (“all fields,” “author,” “title,” “subject,” etc.), facets selected, and the number of results returned. the query stream was subsequently partitioned into task-based search sessions using a combination of syntactic features (word cooccurrence across multiple transactions) and temporal features (session time-outs: we used fifteen minutes of inactivity as a boundary between search sessions). the analysis was conducted over the following datasets: dataset 1. aggregate data of approximately 6 million search transactions conducted between february 13, 2011, and december 31, 2014. we performed quantitative analysis of this set to identify general patterns of system use. dataset 2. a sample of 5,101 search sessions containing 11,478 failed or potentially problematic interactions performed in the basic search mode and 2,719 sessions containing 3,600 advanced searches, annotated with query intent and potential cause of the problem. the searches were performed during eleven twenty-four-hour periods, representing different years, academic http://projectblacklight.org/ https://library.stanford.edu/blogs/stanford-libraries-blog/2014/09/searchworks-30-released information technology and libraries | september 2016 13 quarters, times of the school year (beginning of the quarter, midterms, finals, breaks), and days of the week. this dataset was analyzed to identify common sources of user failure. dataset 3. user feedback messages submitted to searchworks between january 2011 and december 2014 through the “feedback” link, which appears on every searchworks page. while the majority of feedback messages were error and bug reports, this dataset also contained valuable information about how users employed various features of the discovery layer, what problems they encountered, and what features they felt would improve their search experience. for the manual analysis of dataset 2, all searches within a search session were reconstructed in searchworks and, in some cases, also in external sources such as worldcat, google scholar, and google. they were subsequently assigned to one of the following categories: known-item searches (searches for a specific resource by title, combination of title and author, a standard number such as issn or isbn, or a call number), author searches (queries for a specific person or organization responsible for or contributing to a resource), topical searches, browse searches (searches for a subset of the library collection, e.g., “rock operas,” “graphic novels,” “dvds,” etc.), invalid queries, and queries where the search intent could not be established. to identify potentially problematic transactions, the following heuristic was employed: we selected all search sessions where at least one transaction failed to retrieve any records, as well as sessions consisting predominantly of known-item or author searches, where the user repeated or reformulated the query three or more times within a five-minute time frame. we hypothesized that this search pattern could be part of the normal query formulation process for topical searches, but it could serve as an indicator of the user’s dissatisfaction with the results of the initial query for known-item and author searches. we identified seventeen distinct types of problems, which we further aggregated into the following five groups: input errors, absence of the resource from the collection, queries at the wrong level of granularity, erroneous or too restrictive use of limiters, and mismatch between the search terms entered and the library metadata. each search transaction in dataset 2 was manually reviewed and assigned to one or more of these error categories. findings usage patterns our analysis of the aggregate data suggests that keyword searching remains the primary interaction paradigm with the library discovery system, accounting for 76 percent of all searches. however, users also increasingly take advantage of facets both for browsing and refining their searches: the use of facets grew from 25 percent in 2011 to 41 percent in 2014. library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 14 although both the basic and the advanced search modes allow for “fielded” searches, where the user can specify which element of the record to search (author, title, subject, etc.), searchers rarely made use of this feature, relying mostly on the system’s defaults (the “all fields” search option in the basic search mode): users selected a specific search index in less than 25 percent of all basic searches. advanced searching was infrequent and declining (from 11 percent in 2011 to 4 percent in 2014). typically, users engaged in short sessions with a mean session length of 1.5 queries. search queries were brief: 2.9 terms per query on average. single terms made up 23 percent of queries; 26 percent had two terms, and 19 percent had three terms. error patterns the breakdown of errors by category and search mode is shown in figure 1. in the following sections, we describe and analyze different types of errors. figure 1. breakdown of errors by category and search mode input errors input errors accounted for the largest proportion of problematic searches in the basic search mode (29 percent) and for 5 percent of problems in the advanced search. while the majority of such errors occurred at the level of individual words (misspellings or typographical errors), entire search statements were also imprecise and erroneous (e.g., “diary of an economic hit man” instead of “confessions of an economic hit man” and “dostoevsky war and peace” instead of “tolstoy war and peace”). it is noteworthy that in 46 percent of all search sessions containing information technology and libraries | september 2016 15 problems of this type, users subsequently entered a corrected query. however, if such errors occurred in a personal name, they were almost half as likely to be corrected. absence of the item sought from the collection queries for materials that were not in the library’s collection accounted for about a quarter of all potentially problematic searches. in the advanced search modality, where the query is matched against a specific search field, such queries typically resulted in zero hits and can hardly be considered failures per se. however, in the default cross-field search, users were often faced with the problem of false hits and had to issue multiple progressively more specific queries to ascertain that the desired resource was absent from the collection. queries at the wrong level of granularity a substantial number of user queries failed because they were posed at the level of specificity not supported by the catalog. such queries accounted for the largest percentage of problematic advanced searches (63 percent), where they consisted almost exclusively of article-level searching: users either tried to locate a specific article (often by copying the entire citation or its part from external sources) or conducted highly specific topical searches more suitable for a fulltext database. in the basic search mode, the proportion of searches at the wrong granularity level was much lower, but still substantial (20 percent). in addition to searches for articles and narrowly defined subject searches, users also attempted to search for other types of more granular content, such as book chapters, individual papers in conference proceedings, poems, songs, etc. erroneous or too restrictive use of limiters another common source of failure was the selection of the wrong search index or a facet that was too restrictive to yield any results. the majority of these errors were purely mechanical: users failed to clear out search refinements from their previous search or entered query terms into the wrong search field. however, our analysis also revealed several conceptual errors, typically stemming from a misunderstanding of the meaning and purpose of certain limiters. for example, “online,” “database,” and “journal/periodical” facets were often perceived by the user as a possible route to article-level content. even seemingly straightforward limiters such as “date” caused confusion, especially when applied to serial publications: users attempted to employ this facet to drill down to the desired journal issue or article, most likely acting on the assumption that the system included article-level metadata. lack of correspondence between the users’ search terms and the library metadata a significant number of problems in this group involved searches for non-english materials. when performed in their english transliteration, such queries often failed because of users’ lack of library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 16 familiarity with the transliteration rules established by the library community, whereas searches in the vernacular scripts tended to produce incomplete or no results because not all bibliographic records in the database contained parallel non-roman script fields. author and title searches often failed because of the users’ tendency to enter abbreviated queries. for example, personal name searches where the user truncated the author’s first or middle name to an initial while the bibliographic records only contained this name in its full form were extremely likely to fail. abbreviations were also used in searches for journals, conference proceedings, and occasionally even for book titles (e.g., “ai: a modern approach” instead of “artificial intelligence: a modern approach”). such queries were successful only if the abbreviation used by the searcher was included in the bibliographic records as a variant title. a somewhat related problem occurred when the title of a resource contained a numeral in its spelled out form but was entered as a digit by the user. because these title variations are not always recorded as additional access points in the bibliographic records, the desired item either did not appear in the result set or was buried too deep to be discovered. topical searches within the subject index were also prone to failure, mostly because patrons were unaware that such searches require the use of precise terms from controlled vocabularies and resorted to natural language searching instead. user feedback our analysis of user feedback revealed substantial differences in how various user groups approach the search system and which areas of it they find problematic. students were often frustrated by the absence of spelling suggestions, which, as one user put it, “left the users wander [to?] in the dark” as to the cause of searching failure. this user group also found certain social features desirable: for example, one user suggested that having ratings for books would be helpful in his choice of a good programming book. by contrast, faculty and researchers were more concerned about the lack of the more advanced features, such as cross-reference searching and left-anchored browsing of the title, subject, and author indexes. however, there were several areas that both groups found problematic: students and faculty alike saw the system’s inability to assist in the selection of the correct form of the author’s name as a major barrier to effective author searching and also converged on the need for more granular access to formats of audiovisual materials. discussion scope of the discovery system the results of our analysis point to users’ lack of understanding of what is covered by the discovery layer. users are often unaware of the existence of separate specialized search interfaces for different categories of materials and assume that the library discovery layer offers google-like information technology and libraries | september 2016 17 searching across the entire range of library resource types. moreover, they are confused by the multiple search modalities offered by the discovery layer: one of the common misconceptions in searchworks is that the advanced search will allow the user to access additional content rather than offer a different way of searching the same catalog data. in addition to the expanded scope of the discovery tools, there is also a growing expectation of greater depth of coverage. according to our data, searching in a discovery layer occurs at several levels: the entire resource (book, journal title, music recording), its smaller integral units (book chapters, journal articles, individual musical compositions, etc.), and full text. user search strategies the search strategies employed by searchworks users are heavily influenced by their experiences with web search engines. users tend to engage in brief search sessions and use short queries, which is consistent with the general patterns of web searching. they rely on relevance ranking and are often reluctant to examine search results in any depth: if the desired item does not appear within the first few hits, users tend to rework their initial search statement (often with only a minimal change to the search terms) rather than scrolling down to the bottom of the results screen or looking beyond the first page of results. given these search patterns, it is crucial to fine-tune relevance-ranking algorithms to the extent that the most relevant results are displayed not just on the first page but are included in the first few hits. while this is typically the case for unique and specific queries, more general searches could benefit from a relevance-ranking algorithm that would leverage the popularity of a resource as measured by its circulation statistics. adding this dimension to relevance determination would help users make sense of large result sets generated by broad topical queries (e.g., “quantum mechanics,” “linear algebra,” “microeconomics”) by ranking more popular or introductory materials higher than more specialized ones. it could also provide some guidance to the user trying to choose between different editions of the same resource and improve the quality of results of author searches by ranking works created by the author before critical and biographical materials. users’ query formulation strategies are also modeled by google, where making search terms as specific as possible is often the only way to increase the precision of a search. faceted search systems, however, require a different approach: the user is expected to conduct a broad search and subsequently focus it by superimposing facets on the results. qualifying the search upfront through keywords rather than facets is not only ineffective, but may actually lead to failure. for example, a common search pattern is to add the format of a resource as a search term (e.g., “fortune magazine,” “science journal,” “gre e-book,” “nicole lopez dissertation,” “woody allen movies”), and because the format information is coded rather than spelled out in the bibliographic records, such queries either result in zero hits or produce irrelevant results. in a similar vein, making the query overly restrictive by including the year of publication, publisher, or edition library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 18 information often causes empty retrievals because the library might not have the edition specified by the user or because the query does not match the data in the bibliographic record. thus our study lends further weight to claims that even in today’s reality of sophisticated discovery environments and unmediated searching, library users can still benefit from learning the best search techniques that are specifically tailored to faceted interfaces.20 error tolerance input errors remain one of the major sources of failure in library discovery layers. users have become increasingly reliant on error recovery features that they find elsewhere on the web, such as “did you mean . . . ” suggestions, automatic spelling corrections, and helpful suggestions on how to proceed in situations where the initial search resulted in no hits. but perhaps even more crucial are error-prevention mechanisms, such as query autocomplete, which helps users avoid spelling and typographical errors and provides interactive search assistance and instant feedback during the query formulation process. our visual analysis of the logs from the most recent years revealed an interesting search pattern, where the user enters only the beginning of the search query and then increments it by one or two letters: pr pro proq proque proques proquest such search patterns indicate that users expect the system to offer query expansion options and show the extent to which the query autocomplete feature (currently missing from searchworks) has become an organic part of the users’ search process. topical searching while next-generation discovery systems represent a significant step toward enabling more sophisticated topical discovery, a number of challenges still remain. apart from mechanical errors, such as misspellings and wrong search index selections, the majority of zero-hit topical searches were caused by a mismatch between the user’s query and the vocabulary in the system’s index. in many cases such queries were formulated too narrowly, reflecting the users’ underlying belief that the discovery layer offers full-text searching across all of the library’s resources. in addition to keyword searching, libraries have traditionally offered a more sophisticated and precise way of accessing subject information in the form of library of congress subject headings (lcsh). however, our results indicate that these tools remain largely underused: users took advantage of this feature in only 21 percent of all subject searches in our sample. we also found information technology and libraries | september 2016 19 that 95 percent of lcsh usage came from clicks on subject heading links within individual bibliographic records rather than from “subject” facets, corroborating the results of earlier studies.21 there is a whole range of measures that could help patrons leverage the power of controlled vocabulary searching. they include raising the level of patron familiarity with the lcshs, integrating cross-references for authorized subject terms, enabling more sophisticated facetbased access to subject information by allowing users to manipulate facets independently, and exposing hierarchical and associative relationships among lcshs. ideally, once the user has identified a helpful controlled vocabulary term, it should be possible to expand, refine, or change the focus of a search through broader, narrower, and related terms in the lcsh’s hierarchy as well as to discover various aspects of a topic through browse lists of topical subdivisions or via facets. known-item searching important as it is for the discovery layer to facilitate topical exploration, our data suggests that searchworks remains, first and foremost, a known-item lookup tool. while a typical searchworks user rarely has problems with known-work searches, our analysis of clusters of closely related searches has revealed several situations where users’ known-item search experience could be improved. for example, when the desired resource is not in the library’s collection, the user is rarely left with empty result sets because of automatic word-stemming and cross-field searching. while this is a boon for exploratory searching, it becomes a problem when the user needs to ensure that the item sought is not included in the library’s collection. another common scenario arises when the query is too generic, imprecise, or simply erroneous, or when the search string entered by the user does not match the metadata in the bibliographic record, causing the most relevant resources to be pushed too far down the results list to be discoverable. providing helpful “did you mean . . . ” suggestions could potentially help the user distinguish between these two scenarios. another feature that would substantially benefit the user struggling with the problem of noisy retrievals is highlighting the user’s search terms in retrieved records. displaying search matches could alleviate some of the concerns over lack of transparency as to why seemingly irrelevant results are retrieved, repeatedly expressed in user feedback, as well as expedite the process of relevance assessment. author searching author searching remains problematic because of a convergence of factors: a. misspellings. according to our data, typographical errors and misspellings are by far the most common problem in author searching. when such errors occur in personal names, they are much more difficult to identify than errors in the title, and in the absence of library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 20 index-based spell-checking mechanisms, often require the use of external sources to be corrected. b. mismatch between the form and fullness of the name entered by the user and the form of the name in the bibliographic record. for example, a user’s search for “d. reynolds” will retrieve records where “d” and “reynolds” appear anywhere in the record (or anywhere in the author fields, if the user opts for a more focused “author” search), but will not bring up records where the author’s name is recorded as “reynolds, david.” c. lack of cross-reference searching of the lc name authority file. if the user searches for a variant name represented by a cross-reference on an authority record, she might not be directed to the authorized form of the name. d. lack of name disambiguation, which is especially problematic when the search is for a common name. while the process of name authority control ensures the uniqueness of name headings, it does not necessarily provide information that would help users distinguish between authors. for instance, the user often has to know the author’s middle name or date of birth to choose the correct entry, as exemplified by the following choices in the “author” facet resulting from the query “david kelly”: kelly, david kelly, david (david d.) kelly, david (david francis) kelly, david f. kelly, david h. kelly, david patrick kelly, david st. leger kelly, david t. kelly, david, 1929 july 11– kelly, david, 1929– kelly, david, 1929–2012 kelly, david, 1938– kelly, david, 1948– kelly, david, 1950– kelly, david, 1959– e. errors and inaccuracies in the bibliographic records. given the past practice of creating undifferentiated personal-name authority records, it is not uncommon to have one name heading for different authors or contributors. conversely, situations where a single person is identified by multiple headings (largely because some records still contain obsolete or variant forms of a personal name) are also prevalent and may information technology and libraries | september 2016 21 become a significant barrier to effective retrieval as they create multiple facet values for the same author or contributor. f. inability to perform an exhaustive search on the author’s name. a fielded “author” search will miss the records where the name does not appear in the “author” fields but appears elsewhere in the bibliographic record. g. relevance ranking. because search terms occurring in the title have more weight than search terms in the “author” fields, works about an author are ranked higher than works of the author. browsing like many other next-generation discovery systems, searchworks features faceted navigation, which facilitates both general-purpose browsing and more targeted search. in searchworks, facets are displayed from the outset, providing a high-level overview of the collection and jumping-off points for further exploration. rather than having to guess the entry vocabulary, the searcher may just choose from the available facets and explore the entire collection along a specific dimension. however, findings from our manual analysis of the query stream suggest that facets as a browsing tool might not be used to their fullest potential: users often resort to keyword searching when faceted browsing would have been a more optimal strategy. there are at least two factors that contribute to this trend. the first is users’ lack of awareness of this interface feature: it is common for searchworks users to issue queries such as “dissertations,” “theses,” and “newspapers” instead of selecting the appropriate value of the “format” facet. second, many of the facets that could be useful in the discovery process are not available as top-level browsing categories. for example, users expect more granular faceting of audiovisual resources, which would include the ability to browse by content type (“computer games,” “video games”) and genre (“feature films,” “documentaries,” “tv series,” “romantic comedies”). another category of resources commonly accessed by browsing is theses and dissertations. users frequently try to browse dissertations by field or discipline (issuing searches such as “linguistics thesis,” “dissertations aeronautics,” “phd thesis economics,” “biophysics thesis”), by program or department and by the level of study (undergraduate, master’s, doctoral), and could benefit from a set of facets dedicated to these categories. browsing for books could be enhanced by additional faceting related to intellectual content, such as genre and literary form (e.g., “fantasy,” “graphic novels,” “autobiography,” “poetry”) and audience (e.g., “children’s books”). users also want to be able to browse for specific subsets of materials on the basis of their location (e.g., permanent reserves at the engineering library). browsing for new acquisitions with the option of limiting to a specific topic is also a highly desirable feature. library discovery products: discovering user expectations through failure analysis |irina trapido |doi:10.6017/ital.v35i2.9190 22 while some browsing categories are common across all types of resources, others only apply to specific types of materials (e.g., music, cartographic/geospatial materials, audiovisual resources, etc.). for example, there is a strong demand among music searchers for systematic browsing by specific musical instruments and their combinations. ideally, the system should offer both an optimal set of initial browse options and intuitive context-specific ways to progressively limit or expand the search. offering such browsing tools may require improvements in system design as well as significant data remediation and enhancement because much of the metadata that could be used to create these browsing categories is often scattered across multiple fixed and variable fields in the bibliographic records, inconsistently recorded, or not present at all. one of the hallmarks of modern discovery tools has been their increased focus on developing tools that would facilitate serendipitous browsing. searchworks was one of the pioneers to offer virtual “browse shelf” feature, which is aimed at emulating browsing the shelves in a physical library. however, because this functionality relies on the classification number, it does not allow browsing of many other important groups of materials, such as multimedia resources, rare books, or archival resources. call-number proximity is only one of the many dimensions that could be leveraged to create more opportunities for serendipitous discoveries. other methods of associating related content might include recommendations based on subject similarity, authorship, keyword associations, forward and backward citations, and use. implications for practice addressing the issues that we identified would involve improvements in several areas: • scope. our findings indicate that library users increasingly perceive the discovery interface as a portal to all of the library’s resources. meeting this need goes far beyond offering the ability to search multiple content sources from a single search box: it is just as important to help users make sense of the results of their search and to provide easy and convenient ways to access the resources that they have discovered. and whatever the scope of the library discovery layer is, it needs to be communicated to the user with maximum clarity. • functionality. users expect a robust and fault-tolerant search system with a rich suite of search-assistance features, such as index-based alternative spelling suggestions, result screens displaying keywords in context, and query auto-completion mechanisms. these features, many of which have become deeply embedded into user search processes elsewhere on the web, could prevent or alleviate a substantial number of issues related to problematic user queries (misspellings, typographical errors, imprecise queries, etc.), enable more efficient recovery from errors by guiding users to improved results, and facilitate discovery of foreign-language materials. equally important is the continued focus on relevance ranking algorithms, which ideally should move beyond simple keyword information technology and libraries | september 2016 23 matching techniques toward incorporating social data as well as leveraging the semantics of the query itself and offering more intelligent and possibly more personalized results depending on the context of the search. • metadata. the quality of the user experience in the discovery environments depends as much on the metadata as it does on the functionality of the discovery layer. thus it remains extremely important to ensure consistency, granularity, and uniformity of metadata, especially as libraries are increasingly faced with the problem of integrating heterogeneous pools of metadata into a single discovery tool. conclusions and future directions the analysis of the transaction log data and user feedback has helped us identify several common patterns of search failure, which in turn can reveal important assumptions and expectations that users bring to the library discovery. these expectations pertain primarily to the system’s functionality: in addition to simple, intuitive, and visually appealing interfaces and relevanceranked results, users expect a sophisticated search system that would consistently produce relevant results even for incomplete, inaccurate, or erroneous queries. users also expect a more centralized, comprehensive, and inclusive search environment that would enable more in-depth discovery by offering article-level, chapter-level, and full-text searching. finally, the results of this study have underscored the continued need for a more flexible and adaptive system that would be easy to use for novices while offering advanced functionality and more control over the search process for the “power” users, a system that would provide targeted support for the different types of information behavior (known-item look-up, author searching, topical exploration, browsing) and would facilitate both general inquiry and very specialized searches (e.g., searches for music, cartographic and geospatial materials, digital collections of images, etc.). just like discovery itself, building discovery tools is a dynamic, complex, iterative process that requires intimate knowledge of ever-changing and evolving user needs and expectations. it is hoped that ongoing focus on user problems and frustrations in the new discovery environments can complement other assessment methods by identifying unmet user needs, thus helping create a more holistic and nuanced picture of users’ search and discovery behaviors. references 1. marshall breeding, “library resource discovery

zvyagintseva (lzvyagintseva@epl.ca) is the digital exhibits librarian at the edmonton public library in edmonton, alberta. abstract this paper presents the findings of an environmental scan conducted as part of a digital exhibits intern librarian project at the edmonton public library in 2016. as part of the library’s 2016–2018 business plan objective to define the vision for a digital exhibits service, this research project aimed to understand the current landscape of digital displays in learning institutions globally. the resulting study consisted of 39 structured interviews with libraries, museums, galleries, schools, and creative design studios. the environmental scan explored the technical infrastructure of digital displays, their user groups, various uses for the technologies within organizational contexts, the content sources, scheduling models, and resourcing needs for this emergent service. additionally, broader themes surrounding challenges and successes were also included in the study. despite the variety of approaches taken among learning institutions in supporting digital displays, the majority of organizations have expressed a high degree of satisfaction with these technologies. introduction in 2020, the stanley a. milner library, the central branch of the edmonton (alberta) public library (epl) will reopen after extensive renovations to both the interior and exterior of the building. as part of the interior renovations, epl will have installed a large digital interactive display wall modeled after the cube at queensland university of technology (qut) in brisbane, australia. to prepare for the launch of this new technology service, epl hired a digital exhibits intern librarian in 2016, whose role consisted of conducting research to inform the library in defining the vision for a digital display wall serving as a shared community platform for all manner of digitally accessible and interactive exhibits. as a result, the author carried out an environmental scan and a literature review related to digital display, as well as their consequent service contexts. for the purposes of this paper, “digital displays” refers to the technology and hardware used to showcase information, whereas “digital exhibits” refers to content and software used on those displays. wherever the service of running, managing, or using this technology is discussed, it is framed as “digital display service” and concerns both technical and organizational aspects of using this technology in a learning institution. method the data were collected between may 30 and august 20, 2016. a series of structured interviews were conducted by skype, phone, and email. the study population was driven by searching google mailto:lzvyagintseva@epl.ca it is our flagship | zvyagintseva 51 https://doi.org/10.6017/ital.v37i2.9987 and google news for keywords such as “digital interactive and library,” “interactive display,” “public display,” or “visualization wall” to identify organizations that have installed digital displays. a list of the study population was expanded by reviewing websites of creative studios specializing in interactive experiences and through a snowball effect once the interviews had begun. a small number of vendors, consisting primarily of creative agencies specializing in digital interactive services, were also included in the study population. participants were then recruited by email. the goal of this project was to gain a broad understanding of the emergent technology, content, and service model landscape related to digital displays. as a result, structured interviews were deemed to be the most appropriate method of data collection because of their capacity to generate a large amount of qualitative and quantitative data. in total, 39 interviews were conducted. a list of interview questions prepared for the interviews is included in appendix a. additionally, a complete list of the study population can also be found in appendix b. predominantly, organizations from canada, the united states, australia, and new zealand are represented in this study. literature review definitions • public displays, a term used in the literature to refer to a particular type of digital display, can refer to “small or large sized screens that are placed indoor . . . or outdoor for public viewing and usage” and which may be interactive to support information browsing and searching activities.”1 in public displays, a large proportion of users are passers-by and thus first-time users.2 in academic environments, these technologies may be referred to as “video walls” and have been characterized as display technologies with little interactivity and input from users, often located in high-traffic, public areas with content prepared ahead of time and scheduled for display according to particular priorities.3 • semi-public displays, on the other hand, can be understood as systems intended to be used by “members of a small, co-located group within a confined physical space, and not general passers-by.”4 in academic environments, they have been referred to as “visualization spaces” or “visualization studios,” and can be defined as workspaces with real-time content displayed for analysis or interpretation, often placed in in libraries or research department units.5 for the purposes of this paper, “digital displays” refers to both public and semi-public displays, as organizations interviewed as part of this study had both types of displays, occasionally simultaneously. • honeypot effect describes how people interacting with an information system, such as a public display, stimulate other users to observe, approach, and engage in interaction with that system.6 this phenomenon extends beyond digital displays to tourism, art, or retail environments, where a site of interest attracts attention of passers-by and draws them to participate in that site. interactivity the area of interactivity with public displays has been studied by many researchers, with three commonly used modes of interaction clearly identified: touch, gesture, and remote modes. information technology and libraries | june 2018 52 • touch (or multi-touch): this is the most common way users interact with personal mobile devices such as smartphones and tablets. multi-touch interaction on public displays should support many individuals interacting with the digital screen simultaneously, since many users expect immediate access and will not take turns. for example, some technologies studied in this report support up to 30 touch points at any given time, while others, like qut’s the cube, allow for a near infinite number of touch points. though studies show that this technique is fast and natural, it also requires additional physical effort from the user.7 while touch interaction using infrared sensors has a high touch recognition rate, its shortcomings have been identified as being expensive and being influenced by light interference, such as light around the touch screen.8 • gesture: this is interaction is through movement of the user’s hands, arms, or entire body, recognized by sensors such as the microsoft kinect or leap motion systems. although studies show that this type of interaction is quick and intuitive, it also brings “a cognitive load to the users together with the increased concern of performing gestures in public spaces.”9 specifically, body gestures were found not to be well suited to passing-by interaction, unlike hand gestures, which can be performed while walking. hand gestures also have an acceptable mental, physical and temporal workload.10 research into gesturebased interaction shows that “more movement can negatively influence recall” and is therefore not suited for informational exhibits.11 similarly, people consider gestures to be too much work “when they require two hands and large movements” to execute.12 not surprisingly, research suggests that gestures deemed to be socially acceptable for public spaces are small, unobtrusive ones that mimic everyday actions. they are also more likely to be adopted by users. • remote: these are interactions using another device, such as mobile phones, tablets, virtual-reality headsets, game controllers, and other special devices. connection protocols may include bluetooth, sms messaging, near-field communication, radio-frequency identification, wireless-network connectivity, and other methods. mobile-based interaction with public displays has received a lot of attention in research, media, and commercial environments because this mode allows users to interact from variable distance with minimal physical effort. however, users often find mobile interaction with a public display “too technical and inconvenient” because it requires sophisticated levels of digital literacy in addition to having access to a suitable device.13 some suggest that using personal devices for input also helps “avoid occlusion and offers interaction at a distance” without requiring multi-touch or gesture-based interactions.14 as well, subjects in studies on mobile interaction often indicate their preference for this mode because of its low mental effort and low physical demand. however, it is possible that these studies focused on users with high degrees of digital literacies rather than the general public with varying degrees of access and comfort with mobile technologies. user engagement attracting user attention is not necessarily guaranteed by virtue of having a public display. according to research, the most significant factors that influence user engagement with public digital displays are age, display content, and social context. it is our flagship | zvyagintseva 53 https://doi.org/10.6017/ital.v37i2.9987 age hinrichs found that children were the first to engage in interaction with public displays and would often recruit adults accompanying them toward the installation.15 on the other hand, the hinrichs found adults to be more hesitant in approaching the installation: “they would often look at it from a distance before deciding to explore it further.”16 these findings suggest that designing for children first is an effective strategy for enticing interaction from users of all ages. display content studies on engagement in public digital display environments indicate that both passive and active types of engagement exist with digital displays. the role of emotion in the content displayed also cannot be overlooked. specifically, clinch et al. state that people typically pay attention to displays “only when they expected the content to be of interest to them” and that they are “more likely to expect interesting content in a university context rather than within commercial premises.”17 in other words, the context in which the display is situated affects user expectations and primes them for interaction. the dominant communication pattern in existing display and signage systems has been narrowcast, a model in which displays are essentially seen as distribution points for centrally created content without much consideration for users. this model of messaging exists in commercial spaces, such as malls, but also in public areas like transit centers, university campuses, and other spaces where crowds of people may gather or pass by. observational studies indicate that people tend to perceive this type of content as not relevant to them and ignore it.18 for public displays to be engaging to end users, in other words, “there needs to be some kind of reciprocal interaction.”19 in public spaces, interactive displays may be more successful than noninteractive displays in engaging viewers and making city centers livelier and more attractive.20 in terms of precise measures of attention to such displays, studies of average attention time correlate age with responsiveness to digital signage. children (1–14 years) are more receptive than adults and men spend more time observing digital signage than women.21 studies also indicate a significantly higher average attention times for observing dynamic content as compared to static content.22 scholars like buerger suggest that designers of applications for public digital displays should assume that viewers are not willing “to spend more than a few seconds to determine whether a display is of interest.”23 instead, they recommend presenting informational content with minimal text and in such a way that the most important information can be determined in two-to-three seconds. in a museum context, the average interaction time with the digital display was between two and five minutes, which was also the average time people spent exploring analog exhibits.24 dynamic, game-like exhibits at the cube incorporate all the above findings to make interaction interesting, short, and drawing the attention of children first. social context social context is another aspect that has been studied extensively in the field of human-computer interaction, and it provides many valuable lessons for applying evidence-based practices to technology service planning in libraries. many scholars have observed the honeypot effect as related to interaction with digital displays in public settings. this effect describes how users who are actively engaged with the display perform two important functions: they entice passers-by to become actively engaged users themselves, and they demonstrate how to interact with the technology without formal instruction. information technology and libraries | june 2018 54 many argue that a conductive social context can “overcome a poor physical space, but an inappropriate social context can inhibit interaction” even in physical spaces where engagement with the technology is encouraged.25 this finding relates to use of gestures on public displays. researchers also found that contextual social factors such as age and being around others in a public setting do, in fact, influence the choice of multi-touch gestures. hinrichs suggests enabling a variety of gestures for each action—accommodating different hand postures and a large number of touch points, for example—to support fluid gesture sequences and social interactions.26 a major deterrent to users’ interaction with large public displays has been identified as the potential for social embarrassment.27 as an implication, the authors suggest positioning the display along thoroughfares of traffic and improving how the interaction principles of the display are communicated implicitly to bystanders, thus continually instructing new users on techniques of interaction.28 findings technical and hardware landscape the average age of public displays was around three years, indicating an early stage of development of this type of service among learning institutions. such technologies first appeared in europe more than 10 years ago (for example, the most widely cited early example of a public display is the citywall in helsinki in 2007).29 however, adoption in north american did not start until around 2013.the median year for the installation of these technologies among organizations studied in this report is 2014. among public institutions represented in the study population, such as public libraries and museums, digital displays were most frequently installed in 2015. while most organizations have only one display space, it was not unusual to find several within a single organization. for example, for the purposes of this study, the researcher has counted the cube as three display spaces, as documentation and promotional literature on the technology cites “3 separate display zones.” as a result, the average number of display spaces in the population of this study is 1.75. the following modes of interaction beyond displaying video content with digital displays have been observed in the study population in descending order of frequency: • sound (79%). while research on human-computer interaction is inconclusive about best practices related to incorporating sound into digital interactive displays, it is clear, among the organizations interviewed in the environmental scan, that sound is a major component of digital exhibits and should not be overlooked. • touch or multi-touch (46%). this finding highlights that screens capable of supporting multi-user interaction is not consistent across the study population. • gesture (25%): these include tools such as microsoft kinect, leap motion, or other systems for detecting movement for interaction. • mobile (14%). while some researchers in the human-computer interaction field suggest mobile is the most effective way to bridge the divide between large public displays, personalization of content, and user engagement, mobile interactivity is not used frequently to engage with digital displays in the study population. one outlier is north carolina state university library, which takes a holistic, “massively responsive design” approach in which responsive web design principles are applied to content that can be it is our flagship | zvyagintseva 55 https://doi.org/10.6017/ital.v37i2.9987 displayed effectively at once online, on digital display walls, and on mobile devices while optimizing institutional resources dedicated to supporting visualization services. further, as in the broader personal computing environment, the microsoft windows operating system dominates display systems, with 61% of the organizations choosing a windows machine to power their digital display. a fifth (21%) of all organizations have some form of networked computing infrastructure, such as the cube with its capacity to process exhibit content using 30 servers. instead, the majority (79%) of organizations interviewed have a single computer powering the display. this finding is perhaps not surprising, given that few institutions have dedicated it teams to support a single technology service like the cube. users and use cases understanding primary audiences was also important for this study, as the organizational user base defines the context for digital exhibits. the breakdown of these audiences is summarized in figure 1. for example, the university of oregon ford alumni center’s digital interactive display focuses primarily on showcasing the success of its alumni, with a goal of recruiting new students to the university. however, the interactive exhibits also serve the general public through tours and events on the university of oregon campus. other organizations with digital displays, such as all saints anglican school and the philadelphia museum of art, also target specific audiences, so planning for exhibits may be easier in those contexts than in organizations like the university of waterloo stratford campus, with its display wall at the downtown campus that receives visitor traffic from students, faculty, and the public. 44% 33% 22% types of audience academic public both public and academic information technology and libraries | june 2018 56 figure 1. audience types for digital displays in the study population. digital displays serve various purposes, which depend on the context of the organization in which they exist, their technical functionality, their primary audience, their service design, and other factors. interview participants were asked about the various uses for these technologies at their institutions. a single display could have multiple functions within a single institution. the following list summarizes these multiple uses: 1. educational (67%), such as displaying digital collections, archives, historical maps, and other informational. these activities can be summarized in the words of one participant as “education via browse”—in other words, self-guided discovery rather than formal instruction. 2. fun or entertainment (56%), including art exhibitions, film screenings, games, playful exhibits, and other engaging content to entice users. 3. communication (47%), which can be considered a form of digital signage to promote library or institutional services and marketing content. displays can also deliver presentations and communicate scholarly work. 4. teaching (42%), including formal and semi-formal instruction, workshops, student presentations, and student course-work showcases. 5. events (31%), such as public tours, conferences, guest speakers, special events, galas, and other social activities near or using the display. 6. community engagement (28%), including participation from community members through content contribution, showing local content, using the display technology as an outreach tool, and other strategies to build relationships with user communities. 7. research (22%), where the display functions as a tool that facilitates scholarly activities like data collection, analysis, and peer review. many study participants acknowledged challenges in using digital displays for this purpose and have identified other services that might support this use more effectively. content types and management in the words of deakin university librarians, “content is critical, but the message is king,” so it was particularly important for the author to understand the current digital display landscape as it relates to content.30 specifically, the research project encompassed the variety of content used on digital displays as well as how it is created, managed, shared, and received by the audiences of various organizations interviewed in this study. as can be observed in figure 2, all organizations supported 2d content, such as images, video, audio, presentation slides, and other visual and textual material. however, dynamic forms of content, such as social media feeds, interactive maps, and websites were less prevalent. it is our flagship | zvyagintseva 57 https://doi.org/10.6017/ital.v37i2.9987 figure 2. types of content supported by digital displays in the study population. discussions around interest in emergent, immersive, and dynamic 3d content such as games and virtual and augmented reality also came up frequently in the study interviews, and the researcher found that these types of content were supported in only 16 (57%) of the 28 total cases. this number is lower than the total number of interviewees because not all organizations interviewed had content to manage or display. in addition, many organizations recognized that they would likely be exploring ways to present 3d games or immersive environments through their digital display in the near future. not surprisingly, the creative agencies included in this study revealed an awareness and active development of content of this nature, noting “rising demand and interest in 3d and game-like environments.” furthermore, projects involving motion detection, the internet of things, and other sensor-based interactions are also seeing rise in demand, according to study participants. 100 % 61 % 57 % 0 10 20 30 40 50 60 70 80 90 100 content types supported content types

of the organizations interviewed had used some form of content management system (cms), while the rest did not use any tool to manage or organize content. of those organizations that used a cms, 15 (75%) relied on a vendorsupplied system, such as tools by fourwinds interactive, visix, or nec live. the remaining 5 (18%) cms users created a custom solution without going to a vendor. this finding suggests that since the majority of content supported by organizations with digital displays is 2d, current vendor solutions for managing that content are sufficient for the study population at this point. it is unclear how the rise in demand for dynamic, game-like content will be supported by vendors in the coming years. table 1 reflects the distribution of approaches to managing content observed in the study population. 18% 11% 53% 18% 71% content management no system unknown vendor-supplied system in-house created system it is our flagship | zvyagintseva 59

3 10 middleware, automation, and exhibit management middleware can be described as the layer of software between the operating system and applications running on the display, especially in a networked computing environment. for example, most organizations studied in the environmental scan supported a windows environment with a range of exhibit applications, like slideshows, web browsers, and executable files, such as games. middleware can simplify and automate the process of starting up, switching between, and shutting off display applications on a set schedule. as figure 4 demonstrates, the majority of the organizations in the study population (17, or 61%) did not have a middleware solution. however, this group was heterogeneous: 14 organizations (50%) did not require a middleware solution because they ran content semi-permanently or relied on user-supplied content, in which case the display functioned as a teaching tool. the remaining three organizations (11%) manually managed scheduling and switching between exhibit content. in such cases, a middleware solution would be valuable to management of content, especially as the number of applications grows, but it was not present in these organizations. comparatively, 10 organizations (36%) used a custom solution, such as a combination of windows or linux scripts to manage automation and scheduling of content on the display. one organization (3%) did not specify their approach to managing content. these findings suggest that no formalized solution to automating and managing software currently exists among the study population. in addition to organizing content, digital-exhibits services involve scheduling or automating content to meet user needs according to the time of day, special events, or seasonal relevance. as a result, the middleware technology solution supports sustainable management of displays and predictable sharing of content for end users. this environmental scan revealed that digital exhibits and interactive experiences are still in the early days of development. it is possible that new solutions for managing content both at the application and the middleware level may emerge in the coming years, but they are currently limited. information technology and libraries | june 2018 60 figure 4. middleware solutions in the study population. sources of content when finding sources of content to be displayed on digital displays, organizations interviewed used multiple strategies simultaneously. table 2 below brings together the findings related to this theme. table 2. content sources for digital exhibits content source % external/commissioned 64 user-supplied 64 internal/in-house 50 collaborative with partner 43 for example, many organizations rely on their users to generate and submit material (18, or 64%); others commission vendors to create exhibits for them (18, or 64%). in 50% of all cases, organizations also produce content for exhibits in-house. in other words, most organizations used a combination of all sources to generate content for their digital displays. only a few use a single 61% 36% 3% middleware use none custom unknown it is our flagship | zvyagintseva 61 https://doi.org/10.6017/ital.v37i2.9987 source of content, such as the semi-permanent historical exhibit at henrico county public library. others, like the duke media wall, rely entirely on their users to supply content, which employs a “for students by students” model of content creation. additionally, only 12 (43%) of the organizations interviewed had explored or established some form of partnership for creating exhibits. primarily, these partnerships existed with departments, centers, institutes, campus units, and/or students in academic settings, such as the computer science department, faculty of graduate studies, and international studies. other examples of partnerships were with similar civic, educational, cultural, and heritage organizations, such as municipal libraries, historical societies, art galleries, museums, and nonprofits. examples included study participants working with ars electronica, local symphony orchestras, harvard space science, and nasa on digital exhibits. clearly, a variety of approaches were taken in the study population to come up with digital exhibits content. content creation guidelines seven organizations (19%) in the study population shared publicly the content guidelines aimed to simplify the process of engaging users in creating exhibits. these guidelines were analyzed, and key elements were identified that are necessary for users to know in order to contribute in a meaningful way, thereby lowering the barrier to participation. these elements include resolution of the display screen(s), touch capability, ambient light around the display space, required file formats, and maximum file size. a complete list of organizations with such guidelines, along with websites where these guidelines can be found, is included in appendix c. based on the analysis of this limited sample, the bare minimum for community participation guidelines would include clearly outlining • the scope, purpose, audience, and curatorial policy of the digital exhibits service; • the technical specifications, such as the resolution, aspect ratio, and file formats supported by the display; • the design guidelines, such as colors, templates and other visual elements; • the contact information of the digital exhibits coordinator; and • the online or email submission form. it should be noted, however, that such specifications are primarily useful when a cms exists and the content solicited from users is at least somewhat standardized. for example, images, slides, or webpages may be easier for community partners to contribute than video games or 3d interactive content. no examples of guidelines for the latter were observed in the study. content scheduling whereas the middleware section of this study examined the technical approaches to content management and automation, this section explores the frequency of exhibit rotation from a service design perspective. as can be observed in figure 5, no consistent or dominant model for exhibit scheduling has been identified in the study population. generally, approaches to scheduling digital exhibits reflect organizational contexts. for example, museums typically design an exhibit and display it on a permanent basis, while academic institutions change displays of student work or scholarly communication once per semester. the following scheduling models have emerged in the descending order of frequency in the study population. information technology and libraries | june 2018 62 figure 5. content scheduling distribution in the study population. 1. unstructured (29%): no formal approach, policy, or expectation is identified by the organization regarding displaying exhibits. this model is largely related to the early stage of service development in this domain, lack of staff capacity to support the service, and/or responsiveness to user needs. one study participant, for example, referred to this loose approach by noting that “no formalized approach and no official policy exists.” for example, institutions may have frameworks for what types of content are acceptable but no specific requirements on the content subjects. institutions adopting a lab space model (see figure 6) for digital displays largely belong to this category. in other words, content is created on the fly through workshops, data analysis, and other situations as needed by users. in this case, no formal scheduling is required apart from space reservations. 2. seasonal (29%), which can be defined as a period from three to six months and includes semester-based scheduling in academic institutions. many organizations operate on a quarterly basis, so it would seem logical that content refresh cycles reflect the broader workflow of the organization. 3. permanent (21%): in the cases of museums, permanent exhibits may mean displaying content indefinitely or until the next hardware refresh, which might reconfigure the entire interactive display service. no specific date ranges were cited for this model. 4. monthly (10%): this pattern was observed among academic libraries, with production of “monthly playlists” featuring curated book lists or other monthly specials. 5. weekly (7%): north carolina state university and deakin university libraries aim to have fresh content up once per week; they achieve this in part by formalizing the roles needed to support their digital display and visualization services. 29% 29% 21% 10% 7% 4% content scheduling unstructured seasonal permanent monthly weekly daily it is our flagship | zvyagintseva 63 https://doi.org/10.6017/ital.v37i2.9987 6. daily (4%): only griffith university ensures that new content is available every day on its #seemore display; it does this largely by relying on standardized external and internal inputs, such as weather updates and the university marketing department content. staffing and skills one key element of the digital exhibits research project included investigating staffing models required to support a service of this nature. not surprisingly, the theme around resource needs for digital exhibits emerged in most interviews conducted. several participants have noted that one “can’t just throw up content and leave it” while others advised to “have expertise on staff before tech is installed.” data gathered shows that the average full-time equivalent (fte) needed to support digital display services in organizations interviewed was 2.97—around three full time staff members. in addition, 74% of the organizations studied had maintenance or support contracts with various vendors, including av integrators, cms specialists, creative studios that produced original content, or hardware suppliers. hardware and av integrators typically provided a 12-month contract for technical troubleshooting while creative studios ensured a 3month support contract for digital exhibits they designed. the average time to create an original, interactive exhibit was between 9 and 12 months according to the data provided by creative agencies, the cube teams, and learning organizations who have in-house teams creating exhibits regularly. this length of time varies on the complexity of interaction designed, depth of the exhibit “narrative,” and modes of input supported by the exhibit application. additionally, it was important to understand the curatorial labor behind digital exhibits; the author did not necessarily speak with the curator of exhibits, and this work may be carried out by multiple individuals within organizations with digital displays or creative studios. in 20 (57%) of the cases, the person interviewed also curated some of or all the content for the digital display in their respective institutions. in five (14%) of the cases, the individual interviewed was not a curator for any of the content, because there was no need for curation in the first place. for example, displays in these cases were used for analysis or teaching and therefore did not require prepared content. in the rest of the cases (10, or 29%), a creative agency vendor, another member of the team, or a community partner was responsible for the curation of exhibit content. this finding suggests that, while a significant number of organizations outsource the design and curation of exhibits, the majority retain control over this process. therefore, dedicating resources to curation, organization, and management of exhibit content is deemed significant by the organizations represented in the study. in terms of the capacity to carry out digital display services, skills that have been identified by study participants as being important to supporting work of this nature include the following: 1. technical skills (such as the ability to troubleshoot), general interest in technology, and flexibility and willingness to learn new things (74%) 2. design, visual, and creative sensibility (40%), as this type of work is primarily a visual experience 3. software-development or programming-language knowledge (31%) 4. communication, collaboration, and relationship-building (25%) 5. project management (20%) information technology and libraries | june 2018 64 6. audiovisual and media skills (14%), as digital exhibits are “as much an av experience as an it experience,” according to one study participant 7. curatorial, organizational, and content-management skills (11%) the most frequent dedicated roles mentioned in the interviews are shown in table 3. table 3. types of roles significant to digital exhibits work position responses % developer/programmer 11 31 project manager 8 23 graphic designer 6 17 user experience or user interface designer 4 11 it systems administrator 4 11 av or media specialist 4 11 the relatively low percentages represented in this table suggest the distribution of skills mentioned above among various team members or combining multiple skills in a single role, as may be the case in small institutions or those without formalized services with dedicated roles. nevertheless, the presence of specific job titles indicates understanding of various skill sets needed to run a service that uses digital displays. challenges and successes many challenges were identified by study participants related to initiating and supporting a service that uses digital displays for learning. clearly, multiple challenges could be associated with the services related to digital displays within a single organization. however, many successes and lessons learned were also shared by interviewees, often overlapping with identified challenges. this pattern suggests that some organizations can pursue strategies that address challenges faced by their library or museum colleagues while perhaps lacking resources or capacity in other areas related to this type of service. for example, some organizations have observed a lack of user engagement because of limited interactivity of the technology solution they used. others have had successful user engagement largely by investing in technology solutions that provide a range of modes of interaction. it is important to learn from both these areas to anticipate possible pain points and to be able to capitalize on successes that lead to industry recognition and engagement from library customers. table 4 summarized the range of challenges identified. it is our flagship | zvyagintseva 65 https://doi.org/10.6017/ital.v37i2.9987 table 4. challenges related to digital display services challenge identified responses % technical

have been discussed: 1. technical, such as troubleshooting the technology, keeping up with new technologies or upgrades, and finding software solutions appropriate for the hardware selected. 2. content, such as coming up with original content or curating existing sources. in the words of one participant, “quality and refresh of content is key—it has to be meaningful, interesting, and new.” this clearly presents a resource requirement. 3. costs, such as the financial commitment to the service, the unseen costs in putting exhibits together, software licensing, and hardware upgrades. 4. user expectations, such as keeping the service at its full potential, using maximum functionality of the hardware, and software solutions. according to study participants, users “may not want what they think or they say they want,” and to some extent, "such technologies are almost an expectation now, and not as exciting for users.” 5. workflow or project-management strategies specifically related to emergent multimedia experiences that require new cycles of development and testing. 6. time to plan, source, create, troubleshoot, launch, and improve exhibits. 7. service design, such as thinking holistically about the functions of the technology within the larger organizational structure. as one study participant stated, organizations “cannot disregard the reality of the service being tied to a physical space” in that these types of technologies are both a virtual and physical customer experience. 8. organizational culture and policy, in terms of adapting project-based approaches to planning and resourcing services, getting institutional support, and educating all staff about the purpose, function, and benefits of the service. 9. user engagement, particularly keeping users interested in the exhibits and continually finding new and exciting content. various participants have found that “linger time is information technology and libraries | june 2018 66 between 30 seconds to few minutes” and content being displayed needs to be “something interesting, unique, and succinct, but not a destination in itself.” despite the clear challenges with delivering digital exhibits services, organizations that participated in this study have identified keys to success (see table 5). table 5. successes and lessons learned in using digital displays successful

particularly for those institutions that invested in highly interactive and immersive experiences; the rewards are seen in interest and enthusiasm of their user groups. • service design: organizations that have carefully planned the service have found that this technology was successfully serving the needs of their user communities. • promotion and “wow factor” that has brought attention to the organization and the service. it is not surprising that digital displays are central points on tours of dignitaries, political figures, and external guests. further, many have commented that they “did not imagine a library could be involved in such an innovative experiment,” and others have added that their digital displays have “created new conversations that did not exist before.” • leadership and vision at the organizational level, which secures support and resources as well as defines the scope of the service to ensure its sustainability and success: “money is not necessarily the only barrier to doing this service, but risk taking, culture.” • technology solution, where “everything works” and both the organization and users of the service are happy with the functionality, features, and performance of the chosen solution. • flexibility and willingness to learn new things, including being open to agile projectmanagement methods, taking risks, and continually learning new tools, technologies, and processes as the service matures. it is our flagship | zvyagintseva 67 https://doi.org/10.6017/ital.v37i2.9987 • communication and collaboration, both internally among stakeholders and externally by building community partnerships, new audiences, and user participation in content creation. for example, one study participant noted that the technology “has contributed to giving the museum a new audience of primarily young people and families—a key objective held in 2010 at the commencement of the gallery refurbishments.” • workflow and project management for those embracing new approaches required to bring multiple skill sets together to create engaging new exhibits. as one participant has put it, “these types of approaches require testing, improvement, a new workflow and lifecycle for the projects.” • having the right team with appropriate skills to support the service, though this theme was rated as being less significant than designing services effectively and securing institutional support for the technology service. in other words, study participants noted that having in-house programming or design skills is not enough without proper definition of success for digital exhibits services. perceptions institutional and user reception of digital displays as a service to pursue in learning organizations has been identified as overwhelmingly positive, with 87% of the organizations noting positive feedback. for example, one study participant noted the positive attention received by the wider community for the digital display, stating “it is our flagship and people are in general impressed by both the potential and some of the existing content." some participants have gone as far as to say that the reception among users has been “through the roof” and they have “never had a negative feedback comment” about their display. this finding indicates a high degree of satisfaction with such technologies by organizations that pursued a digital display. table 6 further explores the range of perceptions observed in the study. table 6. perception of digital display services perception responses % positive 20 87 hesitation or uncertainty 7 30 concerns about purpose 4 17 concerns about user engagement 4 17 concerns about costs 3 13 negative 3 13 a minority (13%) have noted some negative perceptions, largely related to concerns about costs or functionality of the technology; 30% have observed uncertainty and hesitation on behalf of the staff and users in terms of engagement as well as interrogating its purpose in the organization. for example, one study participant summarizes this mixed sentiment by saying, “the perception is information technology and libraries | june 2018 68 that it’s really neat and worthwhile for exploring new ways of teaching, but that the same features and functions could be achieved with less (which we think is a good thing!).” it is helpful to note this trend in perception, as any new service will likely bring a mixture of excitement, hesitation, and occasional opposition. interestingly, these reactions have originated both from the staff of organizations interviewed and their communities of users. discussion the findings from this study indicate that the functions of the digital displays are highly dependent on the organizational context in which displays exist. this context, in turn, defines the nature of the services delivered through the digital display. for example, figure 6 can be useful in classifying the various ways digital displays appear in the study population, from research and teaching-oriented lab spaces to public spaces with passive messaging or active immersive gamelike digital experiences. figure 6. types of digital displays in the study population. as such, visualization walls might belong in the “lab spaces” category that typically appears in academic libraries or research units and do not require content planning and scheduling. what we might call “digital interactive exhibits” tend to appear in museums and galleries with a primarily public audience and may have a permanent, seasonal, or monthly rotation schedule. however, despite a range of approaches taken to provide content and in terms of use of these technologies, many organizations share resourcing needs and challenges, such as troubleshooting the technology solution, creating engaging content, and managing costs of interactive projects. despite these common concerns, the digital-exhibits services were perceived as being overwhelmingly satisfactory in all types of organizations included in this study because they brought new audiences to the organization and were often seen as “showpieces” in the broader community. the data gathered in the environmental scan demonstrates that there is currently little consistency among digital displays in learning environments. this lack of consistency is seen in content-development methods among study participants, their programming, content it is our flagship | zvyagintseva 69 https://doi.org/10.6017/ital.v37i2.9987 management, technology solutions, and even naming of the display (and, by extension, the display service). for example, this study revealed that no evidently “open platform” for managing content at the application or the middleware level currently exists. a small number of software tools are used by organizations to support digital displays, but their use is in no way standardized, as compared to nearly every other area of library services. there is some indication that digitaldisplay services may become more standardized in the coming years, and more tools, solutions, vendors, and communities of practice will be available. for example, many signage cmss are currently on the market, and the number of game-like immersive experience companies is growing, suggesting extension of these services to libraries in the coming years. only a few software tools exist for creating exhibits, such as intuiface and touchdesigner, though no free, open-source versions of exhibit software are currently available. as well, the growing number of digital exhibits and interactive media companies currently focuses on turnkey—rather than software-as-a-service or platform—solutions. in contrast, some consistency exists in staffing needs and skills required to support the digitalexhibits service. a majority of organizations interviewed agreed that design, software development, systems administration, and project-management skills are needed to ensure digital-exhibits services run sustainably in a learning organization. in addition, lack of public library representation in this study makes it challenging to draw parallels to the library context. adapting museum practices is also not necessarily reliable, as there is rarely a mandate to engage communities and partner on content creation, as there is in libraries. for example, only the el paso (texas) museum of history engages the local community to source and organize content. these findings suggest that digital displays are a growing domain, and more solutions are likely to emerge in the coming years. the cube, compared to the rest of the study population, is a unique service model because it successfully brings together most elements examined in the environmental scan. for example, to ensure continual engagement with the digital display, the cube schedules exhibits on a regular basis and employs user interface designers, systems administrators, software engineers, and project managers. it also extends the content through community engagement, public tours, and stem programming. it has created an in-house middleware solution to simplify exhibit delivery and has chosen unity3d as its platform of choice for exhibit development. limitations only organizations from english-speaking countries were interviewed as part of the environmental scan. it is therefore unclear if access to organizations from non–english-speaking countries would have produced new themes and significantly different results. in addition, as with all environmental scans, the data is limited by the degree of understanding, knowledge, and willingness to share information of the individual being interviewed. particularly, individuals with whom the author spoke may or may not have been technology or service leads for the digital display at their respective institutions. thus, the study participants had a range of understanding of hardware specifications, functionality, and service-design components associated with digital displays. for example, having access to technology leads would have likely provided more nuanced responses around the middleware solutions and the underlying technical infrastructure required to support this service. information technology and libraries | june 2018 70 a small number of vendors were also interviewed as part of the environmental scan even though vendors did not necessarily have digital displays or service models parallel to libraries or museums. they are included in appendix b. nevertheless, gathering data from this group was deemed relevant to the study, as creative agencies have formalized staffing models and clearly identified skill sets necessary to support services of this nature. in addition, this group possesses knowledge of best practices, workflows, and project-management processes related to exhibit development. finally, this environmental scan also did not capture any interaction with direct users of digital displays, whose experiences and perceptions of these technologies may or may not support the findings gathered from the organizations interviewed. these limitations were addressed by increasing the sample size of the study within the time and resource constraints of the research project. conclusion the findings of this study show that the functions of digital-display technologies and their related services are highly dependent on the organizational context in which they exist. however, despite a range of approaches taken to provide content and in terms of use of these technologies, many organizations share resourcing needs and challenges, such as troubleshooting the technology solution, creating engaging content, and managing costs of interactive projects. despite these common concerns, digital displays were perceived as being overwhelmingly positive in all types of organizations interviewed in this study, as they brought new audiences to the organization and were often seen as “showpieces” in the broader community. the successes and lessons learned from the study population are meant to provide a broader perspective on this maturing domain as well as help inform planning processes for future digital exhibits in learning organizations. it is our flagship | zvyagintseva 71 https://doi.org/10.6017/ital.v37i2.9987 appendix a. environmental scan questions digital exhibits environmental scan interview

reviews information retrieval systems; characteristics, testing, and evaluation, by f. wilfred lancaster. new york, john wiley & sons, 1968. 222 pp. $9.00. despite the fact that users retrieve the majority of information that they obtain from collections such as libraries by employing author / title listings in catalogs, information scientists consider only subject listings in discussions of information retrieval this book is no excepton. lancaster defines an information retrieval system as informing a user "on the existence (or non-existence) and whereabouts of documents relating to his request." half of his book treats of characteristics and operation of information retrieval systems and half of testing and evaluating such systems. it is the latter half of the book that distinguishes it from other general introductions to the subject. for the testing and evaluation sections of his book, the author draws heavily on his experience gained while working on the cranfield project as well as at the national library of medicine. at the latter he examined a segment of the real world in a major investigation of the medlars system. an interesting finding of the medlars study that he reports in the book, but on which he does not elaborate, is that there was no relationship between recall ratio percentage and precision ratio percentage for 299 searches examined. in his preface the author expresses the hope that his book will be helpful to students and useful to practitioners. however, a principal function of such an introduction is to guide the reader in further pursuit, or retrieval, of information. in this function the book does not succeed, for seven chapters are barren of references, another eight average somewhat more than three, and the remaining chapter boasts fifty-three. this book will not supplant other general introductions to information retrieval systems, but its discussion of testing and evaluation is a useful introduction. frederick g. kilgour book reviews 177 how to manage your information, by bart e. holm. new york, reinhold book corporation, 1968. 292 pp. $10.00 essential information exceeds the grasp of the keenest minds in all professions. a method of readily obtaining needed resource material can be a particularly knotty problem for those who have no background in appropriate methods of data storage and retrieval. successful operation for many professionals depends directly upon their ability to work out a practical personal system which does not require complex apparatus, excessive cost or time. the purpose of this volume is to help such individuals evaluate their particular needs and design a method of managing information which will be workable and practical. i found the book enjoyable and informative. it immediately recommends itself with its own efficient organization, attractive format, readable style, clever illustrations, and complete indexing. it not only deals with the broad principles necessary for development of a personal information system but also includes specific information of a practical nature on the approach to this problem for professionals in several different fields. the first chapter, which is titled "man the collector", is fascinating to an unsophisticated non-librarian. it outlines the enormous problem of the growth of world-wide information that appears to be proliferating in an almost malignant manner. this served to emphasize a repeatedly stressed cardinal principle: the need to be selective, so that only items of probable real value will be retained. a most valuable chapter for those not experienced in library work relates to the basic principles for retrieval on a single or multiple entry basis. this logically leads into a discussion of how to evaluate the individual's personal need. the operations of specific simple systems, such as optical coincidence, termatrex, keysort and term cards were adequately discussed. individual chapters are devoted to the unique problems that might be encountered by the engineer, the chemist, the physicist, the architect, the doctor, and the archivist, with emphasis on the specific vocabulary needed for proper organization and a brief review of information sources of the various disciplines. the remaining seven chapters deal with proper use of available sources of information, such as keeping current with the literature, use of the modern library, records management, microfilming, and data systems of the present and the future. this volume should be a real value to many who have limited background and are struggling in vain to keep up with the information they need. it can provide practical pointers for those who want to make a serious effort toward establishing and maintaining a system of storage and retrieval of information that does not rely on an all too often faulty memory. ellis a. fuller, m.d. 178 journal of library automation vol. 2/3 september, 1969 the institutes of education union list of periodicals processing system, by j. d. dews and j. m. smethurst. ( symplegades, no. 1). newcastleupon-tyne, oriel press ltd., 1969. 39 pp. sbn ( 69uk) 85362 060 1. 15s. the first half of this small manual is devoted to describing the file .maintenance .and text editing system developed by the university of newcastle-upon-tyne. the second half of the text is devoted to the technical specifications of the newcastle file handling system and refers specifically to the english electric-leo marconi kdf 9 computer. the system described is the application of a series of general purpose programs, that provide the capability of storing, adding, deleting, or changing variable length records, to a union list project for a group of libraries. unfortunately this otherwise well designed system has not been able to do away with the manual "typed slips" back-up file which plagues so many other computerized union list projects. also of interest in this processing system is the use of the work developed at the newcastle computer typesetting research project for computer controlled composition of the final output. section two of seminar on the organization and handling of bibliographic records by computer, newcastle-upon-tyne, 1967 edited by nigel s. m. cox and michael w. grose (archon books, hamden, connecticut, 1967) is the preferred description of all aspects of the system except for those who need the program specifications. alan d. hogan computer based information retrieval systems, edited by bernard houghton. camden, conn., archon books, 1969. 136 pp. $5.00. this book contains six papers that their authors presented at a special course in april 1968 at the liverpool school of librarianship. the objective of the course was to survey the major computer based informational retrieval systems operating in the united kingdom for an audience of prospective users and planners. the book is a successful elementary introduction to large information retrieval systems. in the 1940's and early 1950's, such pioneers as w. e. baten, g. cordonnier, calvin mooers and mortimer taube developed new techniques for information retrieval, a phrase which mooers coined. the major innovation in the new development was "coordinate indexing" or the coordination of index terms at the time of searching. coordination employed simpl~ boolean logic -"and," "or," and "but not." coordinate indexing increased flexibility of searching and number of accesses to documents in contrast to the inflexible, pre-coordinated traditional subject catalogs. book reviews 179 it was also characteristic of the early systems that they dealt with relatively small files of documents not under classical bibliographical control -patents, internal reports, and segments of external report literature. with the advent of the computer, it became feasible to apply the new information retrieval techniques to large files of traditional materials, but to date the major effort has been directed toward huge files of journal articles. it is, therefore, no surprise to find that the five chapters in computer based information retrieval systems that describe systems all depict retrieval from files of journal articles. these five systems are medlars, the science citation index (sci) and its peripherals, chemical titles ( ct) and chemical biological activities ( cbac), a burgeoning institution of electrical engineers (lee ) sponsored project in selective dissemination of electronics information, and a minor computer application to production of the british technology index; the three major, operational projects are of united states origin. selective dissemination is a gt·atifying feature of sci, ct, cbas, and the lee project, for sdi applications take advantage of the computer's potential for personalization by servicing individual users on the basis of their individual needs. the book is a successful primer that provides a useful introduction to computer based systems for retrieval of journal citations from large files. g. a. somerfield's last chapter, "state of the art of computer based information retrieval systems," is more than its title implies, for the last half of the chapter analyzes desirable improvements yet to be achieved. the first half could well serve as an introduction to the book. recently, several worthwhile primers on information retrieval and retrieval systems have appeared. computer based infotimation retrieval systems is still another to provide the brief, clear, elementary introduction that new students, new users, and new planners find most effective in providing an understanding of an unfamiliar field. frederick g. kilgour modern data processing, by robert r. arnold, harold c. hill and aylmer v. nichols. new york, john wiley and sons, inc., 1969. 370 pp. $8.95 this book is an updated version of the authors' previous book, introduction to data processing, john wiley and sons, 1966. the present volume is designed to be used as an introductory text to the concepts of all

study and assessment of worldwide repositories matúš formanek information technology and libraries | march 2021 https://doi.org/10.6017/ital.v40i1.12529 matúš formanek (matus.formanek@fhv.uniza.sk) is assistant professor in the department of mediamatics and cultural heritage, faculty of humanities, university of zilina, slovakia. © 2021. abstract this paper discusses the importance of search engine optimization (seo) for digital repositories. we first describe the importance of seo in the academic environment. online systems, such as institutional digital repositories, are established and used to disseminate scientific information. next, we present a case study of our own institution’s dspace repository, performing several seo tests and identifying the potential seo issues through a group of three independent audit tools. in this case study, we attempt to resolve most of the seo problems that appeared within our research and propose solutions to them. after making the necessary adjustments, we were able to improve the quality of seo variables by more than 59% compared to the non-optimized state (a fresh installation of dspace). finally, we apply the same software audit tools to a sample of global institutional repositories also based on dspace. in the discussion, we compare the seo sample results with the average score of the semi-optimized dspace repository (from the case study) and make conclusions. introduction and state of art search engine optimization (seo) is a crucial part of the academic electronic environment. all their users attempt to process too much information and need to retrieve information fast and effectively. making academic information findable is essential. digital institutional repository systems, used to disseminate scientific information, must present their content in ways that make it easy for researchers elsewhere to find. in this paper, we describe work conducted in the department of mediamatics and cultural heritage at faculty of humanities, university of zilina to improve the discoverability of materials contained within its dspace institutional repository. in the literature review, we examine definitions of website quality and discuss audit tools. then, beginning our case study, we describe the tools applied at our institution. we next describe the selection process of a suitable set of testing tools, focused on the optimization of seo variables of the selected institutional repository running with dspace software, that will be applied later in the case study. the remainder of the article focuses on the identification and resolution of potential seo issues using the three independent online tools we selected. we aim to resolve as many problems as possible and compare the level of achieved improvement with the default installation of dspace 6.3 software which our digital repository is based on. the primary goal is not only to improve the seo parameters of the discussed system but also to increase the searchability of scientific website content disseminated by dspace-based digital repositories. next, we offer insights into worldwide dspace-based repositories. we will show that dspace is currently one of the most widely used software packages to support and run digital repositories. unfortunately, there are many major seo issues that will be discussed later. the secondary objective of this paper is to use the same set of tools to evaluate the current state of the sample of worldwide digital repositories also based on dspace. we will provide the report based on our own findings. in the discussion, the seo score of the optimized dspace (from th e case study) will be mailto:matus.formanek@fhv.uniza.sk information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 2 compared with the results of the current state of seo parameters from the worldwide dspace repositories. finally, our work also carries out many relatively innovative approaches related to digital repositories that have not been extensively debated anywhere in the literature yet. literature review to achieve our goal, we started with a review of existing academic papers. drawing from those papers we describe the current state of academic institutions’ presentation through the internet and search engines. in this sense, we focus on website optimization. the internet, as a medium, is still rapidly expanding. a massive amount of data is communicated, shared, and available online, as noted by christos ziakos: as a result, billions of websites were created, which made it hard for the average (or even advanced) user to extract useful information from the web efficiently for a specific search. the need for an easier, more efficient way to search for information led to the development of search engines. gradually, search engines began to assess the relevance of every website on their indexes compared to the queries provided to them by the users. they took into consideration several website characteristics and metrics and calculated the value of each website using complex algorithms. the enormous number of websites being indexed from search engines, along with the increasing competition for the first search results, led to studying and implementing various techniques in order for websites to appear more valuable in search engines.1 that description applies equally to academic websites as well as commercial ones. a review of relevant literature suggests that it is very important for academic institutions to carefully consider and apply website optimization. there were around 28,000 universities worldwide in 2010, according to one study that monitored research in the field of worldwide academic webometrics.2 the actual number of universities seems to be very similar in 2020. baka and leyni affirm in their working paper that the success or failure of an academic institution depends on its website: “the work of each university exists only when it encounters and interacts with society. their popularity with the public is steadily growing.” what is directly connected with the institution’s presence in the world wide web.3 many authors define the term search engine optimization (seo) as a series of processes that are conducted systematically to improve the volume and quality of traffic from search engines to a specific site by utilizing the working mechanism or algorithm of the search engine. it is a technique of optimization a website’s structure and content to achieve a higher position in search results. the aim is to make increase the website’s ranking in a web search results.4 after an extensive information retrieval in the relevant literature, we can conclude that although seo is currently a widely discussed topic, there is very little accessible scientific literature related to seo applications in the field of digital repositories in general, and none at all in the particular subset of dspace-based repositories. information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 3 website quality many authors generally affirm that there is a positive correlation between academic excellence and the complex web presence of an institution. it confirms that website quality is a factor that can give us a predictive or causal relationship with seo performance.5 numerous tools could be employed to measure the quality of websites, test them closely and produce an seo performance ranking websites ability to properly promote their content through the search engines. for example, the academic ranking of world universities (the shanghai ranking, http://www.shanghairanking.com) has been established for the top 1,000 universities in the world. the website quality is considered by the authors as the quality of institution’s online presence, its ability to properly promote digital content in search engines and finally, in combination, its overall web presence. according to the shanghai ranking list, this is a factor for some “prospective students to decide on whether they will enroll in a specific institute or not. ” 6 a number of recent studies have also attempted to examine the online presence of academic institutions from various points of view. one of the older studies mentioned that the quality of academic websites is very important for students in the process of enrollment.7 another key aspect is the optimized website performance as well as seo and website security.8 audit tools if we want to perform any optimization, we need an appropriate software tool to check a current website’s ranking. according to g2, the world’s largest technology online marketplace, seo software is designed to improve the ranking of websites in search engine results pages without paying the search engine provider for placement. these tools provide seo insights to companies through a variety of different features, helping identify the best strategies to improve a website’s search relevance.9 seo audit software could be used by seo specialists or system administrators, as well. audit software performs one or more of the following functions in relation to seo: content optimization, keyword research, rank tracking, link building, or backlink monitoring. the software then provides reports on the optimization-related metrics.10 many authors stress the importance of a holistic approach to seo factors (24 factors were tested), but it depends on the most effective ones: for example, the quantity and quality of the backlinks, the ssl certificate and so on, which will be described later in this paper.11 the quality of academic websites is very important for researchers, too. they need to disseminate scientific information and communicate it in effective ways. according to some authors, the topic of academic seo (aseo) has been gaining attention in recent years.12 aseo applies seo principles to the search for academic documents in academic search engines such as google scholar and microsoft academic. in another scientific paper, aseo is considered as very similar to traditional seo, where institutions want to make good use of a seo to promote digital scientific content on the internet. beel, gipp, and wilde emphasize the importance for researchers to ensure that their publications will receive a high rank on academic search engines.13 by making good use of aseo, researchers will have a higher chance of improving the visibility of their publications and have their work read and cited by more researchers. in recent years, digital institutional repositories (as the academic systems) have been used as modern ways of promotion and dissemination of digital scientific objects through the internet. digital objects need to reach a wider audience—digital repositories have a form of website interface, interact with students, teachers, or researchers on a daily basis and use the number of citations, articles, theses or other research objects. institutional repositories are affected by search http://www.shanghairanking.com/ information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 4 engines too, so some improvements on repositories’ seo parameters are needed. these factors contribute to a system’s rankings. seo on institutional repositories is not considered an absolutely new scientific topic. kelly stressed eight years ago that google is critical in driving traffic to repositories. he analyzed results from a survey describing the summarization of seo findings for the 24 institutional repositories in the united kingdom. the survey results showed that referring platforms were primarily responsible for driving traffic to those institutional repositories—thanks to many hypertext links in referring domains.14 since then, seo analyses of digital repositories have not been a widely discussed topic in the literature. it is a relatively unique topic to discuss seo on a specific type of digital repository software—dspace, as the most used and popular software for running digital libraries and repositories.15 consequently, this paper focuses on that topic since the dspace-based digital repository is a complex online computer system where some seo parameters could be adjusted. seo audit tools help to identify areas of potential adjustments of those website properties that could help produce higher rankings in search engines (and improve the whole system visibility). audit tools selection process website variables that affect seo can be tested using specialized online software tools. this topic is discussed in detail on a semi-professional level on specialized websites that provide a number of recommendations regarding the use of specific tools as well as evaluations of the tools.16 these tools can keep track of changes in many seo variables. we want to use this approach in our study. however, first we need to choose the appropriate set of these tools. we have found that many seo audit tools mentioned in professional online sources are narrowly specialized.17 for example, they may be focused only on keyword analysis, backlink analysis (for example, ahrefs’ free backlink checker), and so on. in our study, we intend to describe a greater number of seo parameters to monitor rather than emphasize only a few selected ones. we also need tools that are fully available online for free. based on these criteria, we immediately excluded several tools from the selection, because they provide only austere, simple, or restricted information. many tools were excluded because they were limited to a single test with the requirement of registration or provision of an email address. a number of testing tools were also available only in paid versions. we wanted a set of tools that focus on several aspects of seo analyses and evaluate the quality of websites’ seo variables comprehensively. it is important to add that the selected tools results must be comparable, too. after careful consideration of all possibilities, we finally decided to choose three independent seo audit tools in order to make the approach more transparent. the selected tools met most of the criteria mentioned above. however, it is very important to note that many other software tools surely meet the criteria and could also be suitable for testing purposes. based on the scientific literature review, we were not able to identify specific recommendations in this regard; therefore, we have been inspired by the advice offered in the websites and blogs previously mentioned that are focused primarily on seo. our tools selection is as follows (listed in alphabetical order): 1. seo checker (https://suite.seotesteronline.com/seo-checker ) is part of a complex audit software suite called seo tester online suite. seo checker provides tests in the following categories: base, content, speed, and connections to social media. it tracks, among many other parameters, title coherence, text/code ratio, accessibility of microdata, opengraph https://suite.seotesteronline.com/seo-checker information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 5 metadata, social plugins, in-page and off-page links, quality of links, mobile friendliness of the page and many other seo and technical website attributes. regarding restrictions, only two sites can be tested within a 24-hour period. the limit increases to four sites per day after free registration with a valid email address. moreover, there is a 14-day trial period during which all hidden functionalities work. in the free version that we used, a complete report can be viewed only, not downloaded or saved. 2. seo site checkup (https://seositecheckup.com/) was selected based on many positive recommendations from the technically oriented expert website traffic radius.18 seo site checkup is described as “a great seo tool that offers more than 40 checks in 6 different categories (common seo issues like missing metadata, keywords, issues related with absence of connections to social media, semantic web, etc.) to serve up a comprehensive report that you can use to improve results and the website’s organic traffic. it also gives recommendations to fix critical issues in just a few minutes. as a tool, it is very fast and provides in-depth information about the various seo opportunities and accurate results.”19 seo site checkup is appreciated and recognized as number one among other audit tools ranked by the geekflare website.20 another reason we selected this tool for our testing scenario is the fact that the google search engine will offer a link to this tool as the first after entry the search query “seo testing tool” (excluding paid links). seo site checkup is also the fastest of the selected audit tools, which could be considered as another advantage. its disadvantages include the ability to test only one website within 24 hours from one public ip address. 3. woorank (https://woorank.com) is recommended by traffic radius: “woorank offers an in-depth analysis that covers the performance of existing seo strategies, social media and more. the comprehensive report analysis is classified into eight sections for improved readability quotient, and you may also download the report as branded pdf.”21 woorank has obtained the third position among the recommended software tools. trustradius gives it a score of 9.2 out of 10 and users rate it of 4.67 out of 5 stars based on 51 reviews .22 on the one hand, some results are hidden in the free version, but the final score will be shown. on the other hand, woorank has no limit to the number of websites tested per day, but it is the slowest of the selected testing tools. we selected these three seo audit tools because they work independently, their results are comparable to each other, and they offer a quick way to get comprehensive seo analysis results for a tested site. it should be noted that results of some performed tests are hidden, but there is general guidance on how to fix some issues. however, the solution always depends on the specif ic site and used technology. using three different tools adds objectivity because we do not rely on just one tool and a one-sided view of the seo issue. the three selected testers all display results in the same way—test results are always shown as a summarized score in the range of 0 to 100 points (100 represents the best result). a very large set of seo parameters and technical website properties is evaluated in all three cases. these tests are usually divided into several categories (for example, common seo issues, performance, security issues, and social media integration). although similar parameters https://seositecheckup.com/ https://woorank.com/ information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 6 are assessed in all three audit tools, there are still some differences between them. each of the testing tools is unique in a certain area because it also tests a parameter that the others do not deal with or evaluates a website by a different methodology. still, the fact remains that the evaluated seo parameters overlap between the tools. we will not overload this paper with detailed information and technical details of individual partial tests, because they can be easily found on the website of the given test tools (seo site checkup, seo checker online, woorank). we will just mention the common core of main tests: css minification test, favicon test, google search results preview test, google analytics test, h1 heading tags test, html page size test, image alt test, javascript minification test, javascript error test, keywords usage test, meta description test, meta title test, seo friendly url test, sitemap test, social media test, robots.txt test, url canonicalization test, and url redirects test. another specific group consists of tests related to a particular audit tool. thanks to them we can get a more comprehensive view of the tested area of a website’s seo characteristics. for example, seo checker features the following specific tests: title coherence test, unique key words test, h1 coherence test, h2 heading tags test and facebook popularity test. woorank as the second tool extends the basic set of tests with the following: title tag length test, in-page links test, off-page links test, language test, twitter account test, instagram account test, traffic estimations and traffic rank. of course, there is also a set of tests that are parts of two audit tools, but the third one does not deal with them since it is specialized in another area. as we have mentioned, the tools offer a list of suggestions for potential improvement of seo characteristics. the user is informed about an issue, but no instructions or solutions are provided on how to resolve it. the main benefit of this paper lies with its objective to solve specific seo issues. this work may improve the visibility and searchability of dspace-based institutional repositories. a set of the three audit tools described above will be used in the following section. we attempt to identify possible seo issues of the selected institutional repository in the form of a case study. then we aim to fix the identified seo issues and increase its quality of seo parameters as well as demonstrate the potential impact on website traffic caused by performed repairs. all traffic measurements will be based on google analytics data. the institutional repository of the department of mediamatics and cultural heritage (seo case study) background information an older version of our digital repository (based on dspace v5.5) was launched by the department of cultural heritage and mediamatics in april 2017. now, in 2021, the repository makes available online over 180 digital objects, most of them open access under creative commons licenses. the first attempts to create and establish a similar virtual space for digital objects started long ago. several software solutions had been tested for this purpose—for example, invenio and eprints, along with dspace. according to opendoar’s statistics, eprints and dspace have always been the most popular tools for running digital repositories.23 a few years ago, dspace was chosen as the primary software for running a digital repository. since then, the usage of open-source software has been raising. for example, ubuntu server lts (long term support) is used as an operating system, tomcat 8 is used as a web server, postgresql information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 7 assumes the role of a database system, etc. all of those software components are part of a complex digital system and are orchestrated in a virtual environment that is built on an open-source virtualization solution called xcp-ng (in version 8.2). some software components have been switched for others during the development period. based on our experience, the digital repository’s regular visitors were mostly from the staff and students of the department. we initially did not feel a need to improve the visibility of this system to search engines, an oversight that turned out to be a mistake in the long run. we did not perform any search engine optimization on this repository until november 2019, when we coincidentally discovered several scientific articles dealing with seo in the academic environment. after studying the theoretical background, we initiated the practical application process. we applied theory and our experience with dspace software into an seo troubleshooting process within our local repository. most of the optimizing actions related to solving the major seo issues were performed before november 10, 2019. we will describe the seo adjustments we made and derive a list of recommendations for other institutions based on our own experience. initial testing of a clean dspace 6 installation in order to formulate any recommendations related to seo and the administration of dspace digital repositories, it is important to determine and test a starting point. for this purpose, we chose a clean instance of dspace v6.3 with an xml user interface (xmlui)—the latest commonly available stable version. this is the same version that we use in this case study and in our production environment. (a newer version, dspace 7 beta 4, was released by atmire on october 13, 2020).24 no other customization edits were made except a base configuration and necessary url settings. this installation of dspace v6.3 has been tested by the same set of tools mentioned previously. the tests we performed are summarized in table 1, where they are divided into four main seo sections in the first column: common seo issues, social, speed and security. a test name is shown in the second column. the third column is marked as “default installation,” where we display the test results on our clean dspace 6.3 installation. if the tested instance met the criteria of the given test, the green pictogram occurs. when the particular test fails, the red cross is used. the improved state is shown in the fourth column marked as semi-optimized. it is a consequence caused by many important technical changes and seo issues solving process. th is issue will be discussed and described later in this paper; however, a short note about the considered issue is displayed in each row. these notes were retrieved by reports on results. we have used the prefix semiin the last column because we were not able to resolve all detected seo issues—only most of them. all related reasons will be described briefly in the discussion section. when the improving change between states has been made, we have changed a status pictogram (from the red cross to the green correct tick) and set the row color to yellow. the changes leading to improvement (e.g., the yellow rows) will be discussed in detail later, too. recall that we have no need to overload the main text of this paper with detailed technical information about partial tests, because it can be easily found on the websites of the given test tools. table 1 shows the compared results between the non-optimized and semi-optimized states of the dspace repository. based on table 1, the default instance of dspace with basic http and other information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 8 default settings received only 58 points out of 100 in seo site checkup, 50.1 points in seo checker and 32 points in woorank. the average final score is 46.7 points out of 100. although this gained score could be considered as low, the dspace default instance still meets certain basic criteria of seo. in addition, many repository administrators usually do not rely only on a default installation, but they make at least some changes in configuration immediately after the initial installation. inter alia, the first thing to do should be an implementation of https protocol, adding a connection with google analytics services and so on. the improved state is shown in the last column of table 1. whenever we solved an issue, the overall score raised. the semi-optimized repository has obtained a higher score compared to the previous column (default installation). the last column represents the final (however semioptimized) state of technical and seo attributes which we were able to reach at this moment. as shown, many seo issues have been solved. we highlighted them in yellow. on the one hand, some issues remain unsolved. on the other hand, the overall seo improvement is more than noticeable although the final average gained score has not reached the maximum value (100 points). information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 9 table 1. comparison of results between the non-optimized and semi-optimized states of dspace repository. test name state default installation (before optimization) semi-optimized (after a few optimization steps) meta title test, title tag length the title tag is set, but the meta title of the webpage (dspace home) has a length of 11 characters. it is too low. the title tag has been set to “digitálny repozitár katedry mediamatiky a kultúrneho dedičstva” (note: in slovak language). title coherence test the keywords in the title tag are included in the body of the page the title of the page seems optimized. meta description test no meta-description tag is set. meta-description tag has been set.

74.66/100 resolving major seo issues this section will look at how we resolved the major seo issues that the tools detected. this is the key technical part because most of mentioned issues highlighted in table 1 were solved and described. the following technical and seo adjustments have been implemented and tested in order to improve the average final score by 59.87% (by 27.96 points, from 46.7 to 74.66 points)— comparing the fresh installation of dspace against the semi-optimized one. all the following solution procedures are based on our own experience, experiments, and research carried out in the area of digital repositories and their optimization as virtual spaces. during the solving process, we follow the order of issues stated in table 1 and describe them in more details in the dspace v6.3 environment and an xml user interface (xmlui). the following procedures may differ slightly if you are using a different version of dspace or another graphic interface (for example jspui). examples of code are given in monospaced font. title, description, and keywords tags in a website header this criterion requires filling in the specific metadata (e.g., metacontent) fields in the page’s html code. the search engines process them automatically to find out what the website is about. information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 14 to solve these seo issues change a website title (in default “dspace home”) located in the language translations config files in the folder path. /dspace/webapps/xmlui/i18n/messages_en.xml. find the appropriate key and change the value. all content in this file is fully customizable. next, edit dspace’s page structure config file (in path /themes/mirage/lib/xsl/core/page-structure.xsl) in order to add the metadata content: • a meta-description tag • a keywords tag • an author tag with a carefully selected content and length just below the main <head> tag, as shown in the example: <head> <meta content="the digital repository receives, stores, indexes, preserves and disseminates the digital content created by the department of media and cultural heritage” name="description" /> <meta name="keywords" content="digital repository, the department of mediamatics and cultural heritage, kmkd, mkd, faculty of humanities, digital archive, dspace"/> <meta content="matúš formanek" name="author" /> note: do not forget the termination characters />. the keywords should be included in title and meta–description tags. several other seo parameters are affected by performing those steps, for example, google search results preview test, keywords usage test, unique key words test and keywords concentration test. language declaration the language declaration is very important for search engines to identify the primary language of the website content. if a declared language is missing in a website, you can define it by adding the following line into the page-structure.xsl file (the process is similar to adding keywords and description tag as explained above). edit the page-structure.xsl file (with vim or another text editor, for example) and add a statement like the following above the main <head> tag: <html xml:lang="sk" xmlns="http://www.w3.org/1999/xhtml"></html> note: “sk” is an abbreviation for “slovak language” as stated in w3 namespaces. more information is available at https://www.w3.org/tr/xml/ . google analytics, robots.txt and sitemap implementation the connection between a website and google analytics services enables google analytics to track users’ behavior and understand as they interact with this site. it is the basis of web analysis. the “robots.txt” and “sitemap.xml” files are simple text files which are required for search engines to specify the website structure and additional information about it. https://www.w3.org/tr/xml/ information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 15 to enable google analytics services, insert a ua code identifier (id is a string), obtained from google analytics, into the dspace.cfg config files located in the dspace home folder. in that file find the key/row named “xmlui.google.analytics.key=” and insert the corresponding ua identifier there. next, it is needed to uncomment the row with the key “xmlui.controlpanel.activity.max = 250” in the same “dspace.cfg” file. finally, uncomment the row below in the “xmlui.xconf”file located in the path /dspace/config/ and restart the tomcat service: <aspect name="statisticsgoogleanalytics" path="resource://aspects/statisticsgoogleanalytics/" /> the “robots.txt” file is commonly used and enabled in dspace, but many seo audit tools are not able to detect it successfully because this file is located in path other than the expected default one. to enable robots.txt file detection, copy the file /dspace/webapps/xmlui/static/robots.txt to the root of the tomcat folder (usually located in path /var/lib/tomcat8/webapps/root). finally, restart the tomcat web service. a sitemap for a currently running dspace instance is available in the “robots.txt” file mentioned above. edit this file and set an appropriate url for the sitemap location. enabling connections with social media this criterion detects a hyperlink (or other metadata) connection between a website and popular social media, such as facebook, twitter, etc. the primary goal is to promote the digital content. this subsection deals with social media connections with a dspace-based repository. a simple creation of a profile or a site on a social network related to a repository is considered an essential example of good practice. however, an appropriate form of connection between sites must be created, too. naturally, further endorsement of this system through social networks is another key step. social media-oriented tests are performed by each seo audit tool nowadays. the detected connection with social media could have a big impact on the site’s popularity, as well as on the gained seo final score. there are many ways how to establish these connections: connection with facebook, instagram and twitter—a direct link from the homepage, for example: to add a link to a facebook site profile, edit the page-structure file (/dspace/webapps/xmlui/themes/mirage/lib/xsl/core/page-structure.xsl) just below a div tag with id “ds-footer-wrapper”. for example: <div id="ds-footer-wrapper"> <div id="ds-footer"> <div id="ds-footer-left"> <a href=https://www.facebook.com/digitalnyrepozitar/ target="_blank">facebook page</a> </div> a direct link to other media could be similarly added, too, if needed. after accomplishing this procedure, the test for social media (e.g., facebook) passes correctly. however, it should be done by adding microdata or other inserted structured metadata into the html code. please, do not forget to add the appropriate links in the schema.org metadata, too (see below). it is advisable to periodically promote the repository through the posts on facebook and other social media. https://www.facebook.com/digitalnyrepozitar/ information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 16 twitter optimization through a twittercard insertion—some audit tools perform a specific test focused on a presence of so-called twittercard html markup on the website to optimize future tweets. only one card type per-page is supported. here is an example for twittercard consisting of four parts (card, title, image, description). after customizing the following code to reflect your institution’s information, insert the following code just below the <head> tag in the page-structure.xsl file: <meta name="twitter:card" content="digital repository of the department of mediamatics and cultural heritage"/> <meta name="twitter:title" content=" digital repository of the department of mediamatics and cultural heritage "/> <meta name="twitter:image" content="https://opensenselabs.com/sites/default/files/inlineimages/screenshot%202018-07-02%2019.25.45.png"/> <meta name="twitter:description" content=" the digital repository receives, stores, indexes, preserves and disseminates the digital content created by the department of media and cultural heritage "/> note: the url of the twitter:image must be absolute. placing a repository link into other (especially high-ranked) websites is also highly recommended. the gained score as well as website traffic will surely rise by implementing those links. opengraph protocol integration this criterion refers to the presence of specific metadata object (opengraph element) in the website. it is very important for website objects’ visibility in social networks. many website objects could be described through opengraph metadata protocol tags.25 the woorank audit tool verifies whether opengraph tags on your webpage have been detected or not. opengraph protocol adoption is a way to enable the integration of any website with social media or other platforms. you will be able to control how your websites are presented when they (e.g., their links) are shared across social media with metadata stored in opengraph protocol tags (all documentation is available at https://ogp.me/). to adopt the main opengraph elements, insert the following code (updating it for your institution) just below the <head> tag in the page-structure.xsl file: <meta property="og:title" content="digital repository of the department of mediamatics and cultural heritage"/> <meta property="og:url" content="https://repozitar.kmkd.uniza.sk/xmlui"/> <meta property="og:description" content=" the digital repository receives, stores, indexes, preserves and disseminates the digital content created by the department of media and cultural heritage "/> <meta property="og:locale" content="sk_sk"/> <meta property="og:locale:alternate" content="en_us"/> <meta property="og:type" content="website"/> <meta property="og:image:type" content="text/html"/> <meta property="og:image" content="https://opensenselabs.com/sites/default/files/inlineimages/screenshot%202018-07-02%2019.25.45.png"/> note: the url of the tag “og:image” must be absolute. structured data integration (schema.org) this criterion analogously deals with the presence of objects described by another standard for structured metadata, schema.org: https://ogp.me/ information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 17 schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the internet. schema.org uses vocabularies that can be used with many different encodings, including rdfa, microdata and json -ld.26 google, microsoft. and others already use these vocabularies to power rich, extensible experiences with a shared collection of schemas.27 a lot of information included in a dspace repository can be described by schema.org vocabulary. there are three main ways how to do that—through jsonld, rdfa, and microdata. json-ld is a javascript notation embedded in a <script> tag in the page head or body. the markup is not interleaved with the user-visible text, which makes nested data items easier to express, such as the country of a postaladdress of a musicvenue of an event. also, google can read json-ld data when it is dynamically injected into the page's contents. rdfa is an html5 extension that supports linked data by introducing html tag attributes that correspond to the user-visible content that you want to describe for search engines. rdfa is commonly used in both the head and body sections of the html page. microdata is an open-community html specification used to nest structured data within html content. like rdfa, it uses html tag attributes to name the properties you want to expose as structured data. it is typically used in the page body, but can be used in the head. 28 google recommends using json-ld for structured data whenever possible.29 we also recommend using json-ld (an extension of original json suitable for linking data) vocabulary to express additional information about entities related to a dspace repository, for example information about the organization and many other entities. to enter schema.org elements expressed in json-ld in order to increase the searching impact of a dspace instance on the search engines, insert a script like following into the page-structure.xsl file (/dspace/webapps/xmlui/themes/mirage/lib/xsl/core/page-structure.xsl) just below a div tag marked with id “ds-footer-wrapper”. <script type="application/ld+json"> { "@context" : "http://schema.org", "@type" : "educationalorganization", "name" : "digital repository of the department of mediamatics and cultural heritage", "department" : "the department of mediamatics and cultural heritage", "url" : "https://repozitar.kmkd.uniza.sk/xmlui", "sameas" : [ “https://www.facebook.com/digitalnyrepozitar/” "https://www.instagram.com/katedramkd/", "https://twitter.com/mediamatikakd" ], "address": { "@type": "postaladdress", "streetaddress": "univerzitna 8215/1", "addressregion": "zilina", "postalcode": "01026", "addresscountry": "sk" } } </script> https://www.facebook.com/digitalnyrepozitar/ information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 18 many elements like the one above could be added, too. see the documentation available at https://schema.org/. a free online tool for testing structured data is available from google at https://search.google.com/structured-data/testing-tool?hl=en. reducing repository website size during transfer the primary goal of this criterion is to measure a reduction of website size which is conducted by the enabled compression of website code parts. this reduction can be achieved by enabling compression methods for html and other file formats when they are transmitted from a server to a client. the tomcat webserver (which is an essential website component for dspace repositories) allows turning on gzip compression and so -called javascript minification. to enable gzip on the tomcat webserver, edit the tomcat’s configuration file “server.xml” located in its home directory. under the tag “<service name="catalina">” edit a corresponding connector tag so it looks like the following example. changes in the code are shown in bold: <connector port="8080" maxhttpheadersize="8192" maxthreads="150" minsparethreads="25" maxsparethreads="75" enablelookups="false" redirectport="8443" acceptcount="100" connectiontimeout="20000" disableuploadtimeout="true" compression="on" compressionminsize="1024" nocompressionuseragents="gozilla, traviata" compressablemimetype="text/html,text/xml,text/plain,text/javascript,text/css,application/ x-javascript,application/javascript"/> the compressablemimetype contains the formats you want to compress. important note: if you deal with https (and corresponding port number 443 instead 8080), you must set the options stated above into the corresponding connector (443), too. otherwise, the compression will be enabled only in simple http (running on port number 8080). javascript minification can be enabled in a “dspace.cfg” configuration file located usually in a dspace home directory (/dspace/config/). change the key value from false to true in the following rows: xmlui.theme.enableminification = true xmlui.theme.enableconcatenation = true setting a canonical link this requirement deals with the presence of a canonical link used by search engines. “a canonical link is included in the html code of a webpage to indicate the original source of content. this markup is used to address seo problems with duplicate content which arise when different pages with different urls contain identical or nearly identical content.”30 the problem with duplicated content can arise, for example, when a webpage is accessible with or without a www prefix in its url or a webpage is accessible via http and https protocols. “for seo purposes, the canonical link shows google and other search engines which url corresponds to the original source of content and should be shown in search results. it is added as a meta tag to every url version of a given webpage and indicates the canonical url.”31 https://schema.org/ https://search.google.com/structured-data/testing-tool?hl=en information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 19 after a necessary customization, insert the following row just below the <head> tag in dspace’s page-structure.xsl file (/dspace/webapps/xmlui/themes/mirage/lib/xsl/core/page-structure.xsl) : <link rel="canonical" href="https://repozitar.kmkd.uniza.sk/xmlui/" /> https adoption the adoption of https is required for a secure data transfer. this criterion inspects if https is enabled and what quality it displays. https is an essential component that supports website security for sites available via the internet. we pointed out the importance of http adoption in a dspace respiratory interface in our previous research papers.32 firstly, you should prepare a file called the certificate signing request, or csr, that will be used by the certificate authority of your choice to generate the certificate ssl. the process of https configuration on the tomcat webserver (used natively in dspace repositories) is widely described online (for example available at https://www.mulesoft.com/tcat/tomcat-ssl). secondly, you should configure a corresponding connector for https (port 443) in tomcat´s configuration file. we strongly recommend following those instructions and to use dspace instance only with https, among other major security risks, because dealing with simple http has surely a very negative impact on seo final score. google and other search engines strongly prefer websites with https enabled. discussion about the seo issues solving process in the previous subsections, we have offered solutions of selected major seo issues that can be relatively easily resolved in systems based on dspace and its website technologies. however, in practice, it is unrealistic to expect a 100% optimization level and final solutions for all detected problems. therefore, we intentionally did not mark the second state of the system (shown in table 1) as fully optimized but only semi-optimized. some of the issues we detected remain unsolved despite all our efforts. there are several reasons. one of the most important of them is the fact that dspace software, like many complex systems, cannot be easily modified without programming experience. therefore, resolving some complicated issues is beyond the scope of this article. another significant reason is that we lacked knowledge about some issues at the time of writing this paper and therefore we could not solve them. this situation creates an opportunity for further research and proposals for solutions of unsolved issues in this specific area, which the professional public would certainly like to welcome. taken together, it could be said that the changes we have made, helped to objectively increase the average seo score by 59 percent compared to the default installation. all the successfully performed actions improved the search results of our repository and rapidly increased its. we suppose that all related seo actions can affect website traffic. most major issues discussed in this case study were resolved before november 10, 2019. therefore, we prepared an analysis of the repository traffic which involved 30-day period before and after this date (one from october 11 until the change, the other from the change until december 10, 2019). we determined the impact of performed seo actions on website traffic. the results are satisfactory because the number of established relations has significantly raised. the impact of organic search (through google, for example) has increased traffic by 47.67% (from 86 to 127 sessions). the number of sohttps://www.mulesoft.com/tcat/tomcat-ssl information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 20 called referral sessions (sessions initiated from social media and other referral sites) has increased by 193.75% (from 16 to 47 sessions). users spent much more time on the website and viewed more pages on average (an increase of up to 159%). we view the significant traffic increase as a proof that the seo changes we implemented helped to promote use of the digital repository’s content. in the next section, we want to compare the quantitative improvement of seo parameters, which we have been able to achieve to this point, with the results achieved in global testing of worldwide dspace-based repositories by the same set of tests. next, we can easily compare the results gained in the local case study with the current state determined in the worldwide area of dspace repositories. testing seo parameters of worldwide dspace-based repositories there are several thousand digital repositories around the world. most of them (41.1% according to roar registry data and over 39% according to the opendoar registry) are based on dspace software.33 therefore, we also focus our research exclusively on dspace-based repositories in this study. as we have pointed out in the methodology, the second objective of this paper is to briefly describe a current state of seo parameters related to worldwide dspace-based digital repositories. next, we will discuss the comparison of results obtained from the case study and exploration of worldwide repositories. methodology according to the facts stated above, we would like to know more details about the quality of seo parameters related to worldwide repositories running with dspace. we decided to use one of the two most authoritative registries of digital repositories: the registry of open access repositories (roar) and the directory of open access repositories (opendoar). roar is hosted at the university of southampton in the united kingdom and is available online at http://roar.eprints.org/. opendoar is available at https://v2.sherpa.ac.uk/opendoar/. both are quality-assured global directories of academic open access repositories. they “enable the identification, browsing and search for repositories, based on a range of features, such as location, software or type of material held.”34 we decided to utilize the roar registry as the source for a sample list because it is possible to filter systems based on specific criteria. we applied these three filters on march 11, 2020: any country, any repository type, and dspace software. we downloaded the raw data in a text/csv file with 1,977 records. each record had a separate row for each repository. each row has a sequence number and includes many columns with much additional information. only a few columns were necessary for our purpose—the columns marked as “title” and “home_page”. other columns were removed. all changes in the list were performed using microsoft excel. for further evaluation, we selected a random sample from this file. we used a sample size online calculator (available at https://www.calculator.net/sample-size-calculator.html ) to do that. we had set the following values for statistical parameters: http://roar.eprints.org/ https://v2.sherpa.ac.uk/opendoar/ https://www.calculator.net/sample-size-calculator.html information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 21 • population size: 1,977 (the total count of dspace repositories in roar) • confidence level: 95% • margin of error: 10% a sample size of 92 was automatically calculated for these values of statistical parameters. next, we used a random number generating function integrated in excel (randbetween(1,1977)) that generated 92 random numbers from the strictly defined range. each randomly generated number corresponds with the matching row number in the table of repositories downloaded from the roar. we could choose 92 dspace repositories for testing purposes. in this way, objectivity in the selection of the research sample was ensured. we also tested the sample for duplicate entries, to ensure that no repository was selected twice. we had to do so, because the random generating function does not guarantee that only unique integer values will be generated. figure 1 shows the distribution histogram of randomly generated values from 1 to 1,977. figure 1. distribution histogram of randomly generated values. then, we attempted to test each of 92 selected repositories with three audit tools. the results are discussed in the next section. information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 22 test results table 2 shows a part of the table with results. this table does not contain any urls or titles to ensure anonymity, however we can provide this information upon request. a second-level domain name is only displayed in each row as well as the corresponding scores gained in tests. the maximum value is 100 points in every case. the rows in the table were sorted by the calculated average score from high to low. many rows are omitted due to the table length (one row for the each from 92 repositories). the last tested repository has a sequence number equal to 65. the repositories with a higher sequence number have no gained score (n/a state), due to inaccessibility. table 2. test results the repository sequence number the first and secondlevel domain name seo site checkup seo checker woorank average 1 econstor.eu

6, 2020. it took a lot of time, because we were limited by the reuse restrictions (described above) in the audit tools’ free accounts. these restrictions meant that only a few tests could be performed daily even though we used several public ip addresses to speed up the overall testing process. among other items, we identified a startling problem related to nonfunctional repository urls. thirty one out of 92 tested repositories were unavailable between march and april 2020 (in table 2, they are shown with n/a status). on april 6, 2020, at the end of testing period, we tried to test the unavailable systems once again. four of them had become functional, so the final number of information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 23 really tested repositories rose to 65 (out of 92). the remaining 27 (29.35 percent of the total) repositories were still offline or unavailable. it is possible that the urls stated in roar’s records have been out-of-date. n/a values were ignored in all calculations and had no impact on the final average score or other statistical parameters. only 65 fully functional dspace-based worldwide repositories were involved and were used for testing purposes. for better visualization of the partial as well as summarized results, we have decided to use a graph instead of a table. figure 2 shows the results of 65 repositories sorted by an average gained score (from highest to lowest) that was calculated from three partial scores gained in seo site checkup, seo checker and woorank testing tools. so, there are three corresponding partial discrete values (colored dots) shown for each repository in figure 2. the calculated average score for each one is marked in red color. the red dotted line provided the most valuable results for this partial section. figure 2. results of 65 involved repositories. the repositories that gained a higher score (e.g., better seo results) are, logically, situated on the left side of figure 2. on the right side are systems with lower scores. non-functional systems (n/a) are not displayed at all. the underlying frequency distribution graph of average score (the red dotted line in the previous figure) is available in figure 3. information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 24 figure 3. underlying frequency distribution graph of average score based on the submitted results manifested in the previous figures we can make the conclusion with a relatively high degree of reliability: the large part of dspace-based repositories registered in roar (over 29%) were unavailable at the time of writing the article. it is alarming, because roar is still considered as an authoritative registry for open access repositories and should not contain any invalid data. an average score of functional repositories, gained during the testing period, is very similar between audit tools: 53.47 points in seo site checkup, 48.08 points in seo checker and 49.22 points in woorank. standard deviations of population are comparable, too. finally, most of the tested repositories (19) gained a score from the interval (55.60) as is shown in fig ure 3; however, the average seo score of all tested dspace-based repositories was only 50.26 points out of 100 (data from march/april 2020), which is an adequate value for a relatively low level of search engine optimization of those systems. results and discussion we have obtained complete insights on the seo parameters of worldwide dspace-based digital repositories in the previous section. now, we can compare this data with the results gained during the case study solving process described above. the situation is briefly pointed out in table 3. information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 25 table 3. comparison of fresh installation, semi-optimized installation and average worldwide score seositechechup seo checker woorank total average score calculated improvement (%) fresh dspace installation 58 50.1 32 46.7 100 a reference point semi-optimized state of the institutional repository of the department of mediamatics and cultural heritage 81 78 59 74.66 +59.87 the average score of worldwide dspacebased repositories 53.47 48.08 49.22 50.26 +7.62 based on table 3, it is proposed that the fresh, non-optimized dspace obtained a slightly worse score than the worldwide average. although a few seo issues still remain in our semi-optimized dspace instance, the state of seo parameters is much better than the score gained in any other discussed cases. if we considered a fresh dspace installation as a reference point (100 percent), the improvement level would be shown in the last column of table 3. semi-optimized dspace offers an improvement up to 59.87% compared to fresh (non-optimized) dspace installation. there is no significant difference (up to 7.62%) in seo quality between the worldwide average repository and non-optimized dspace instance. the results they have obtained are very similar. as we have mentioned at the beginning of our paper, a higher score obtained in tests is not the primary objective. the main goal is to improve visibility and the content searchability of digital repositories, as well as to improve their security and ways of promotion through the social/new media. conclusion this study exposed a serious research in the field of digital repositories running dspace software—as the most popular tool for this purpose. we have shown that significant seo improvement of more than 59% can be achieved thanks to a few simple modifications within the dspace configuration and associated used application layers (tomcat webserver, etc.). some of those technical optimization steps can be performed in a relatively simple way, using previously described solving procedures and a wide theoretical background. we have publicly presented the reports and solving explanations of the most common and major seo problems that dspace repositories usually face. this paper is one of the first academic studies to deal with seo issues related to digital repositories, especially those that are running dspace software. we realize that we have not been able to solve all of the identified problems completely. therefore, the following seo issues remain unresolved: information technology and libraries march 2021 solving seo issues in dspace-based digital repositories | formanek 26 • h1 heading tags test • h1 coherence test • seo friendly url test • inline css test • page cache test (server-side caching) • cdn usage test • image, javascript, css caching tests • css minification test • url canonicalization test some of these could probably be solved more easily than others; however, the system url cannot be changed without difficulty to be considered as seo friendly. in conclusion, all of the above presents a great opportunity for further discussions and research in this field. the current state of seo parameters related to dspace repositories has been presented as unsatisfactory, as shown in the test results. conclusively, the results of our research indicate that there is a small difference in seo quality between the average results obtained by global, worldwide dspace repositories and the non-optimized installation of dspace v6.3 (the difference is approximately 7% in global repositories’ favor). it seems that the most of these systems are not currently optimized in terms of seo and other technical website parameters. the second major finding indicates that the metadata records stored in the roar are not always accurate and may be incorrect or obsolete. in order to make this finding more objective we must note that the roar’s storage had a major failure, which could lead to the harvesting service failing. (more information about the failure is available at http://roar.eprints.org/.) finally, we recommend periodically re-testing the level of search engine optimization on digital repositories. the “search engine algorithms tend to change often, and new factors are added while outdated or not effective factors are excluded. this is why web developers must check the algorithm changes and adjust their websites in order to not only achieve but also maintain high ranking in search engines.”35 we believe that our work will also contribute to the initiation of cooperation among other experts in order to resolve remaining seo problems. ultimately, we hope that all presented efforts and recommendations will help repository administrators, users, scientists, researchers, teachers as well as students and other members of the general public to find what they need in the virtual spaces like digital repositories more quickly and efficiently. endnotes 1 christos ziakis et al., “important

https://doi.org/10.6017/ital.v40i4.13353 eric ely (eely@wisc.edu) is a phd candidate in the information school, university of wisconsin-madison. © 2021. abstract post-secondary education in the 21st century united states is rapidly diversifying, and institutions’ online offerings and presence are increasingly significant. academic libraries have an established history of offering virtual services and providing online resources for students, faculty, staff, and the general public. in addition to these services and resources, information on academic library websites can contribute to an institution’s demonstration of value placed on diversity, equity, and inclusion (dei). this article analyzes the dei statements of a library consortium’s member websites to explore how these statements contribute to institutional construction of, and commitment to, diversity, equity, and inclusion. descriptive analysis revealed 12 of 16 member libraries had explicitly labeled dei statements in november 2020, with an additional member updating their website to include such a statement in early 2021. content analysis examined how the existing statements contributed to institutional value of and commitment to dei, and multi-modal theory explored the communicative aspects of dei statement content. analysis revealed vague conceptualizations of diversity and library-centered language in dei statements, while a subset of statements employed anti-racist and social justice language to position the library as an active agent for social change. implications and avenues for future research are discussed. introduction according to the national center for education statistics, 44% of us resident students attending us degree-granting postsecondary institutions were non-white during the fall 2017 term.1 academic libraries can utilize their online presence to engage diverse students. these sites provide users with various services, resources, and information. the convenience of remote access may encourage physical library use and encourage lasting library utilization. clearly demonstrating institutional values of diversity, equity, inclusion (dei) sends a message to users. given the amount and variety of content on academic library websites, creating a shared vision regarding the purpose of academic library websites is challenging.2 as instances of racial discrimination and marginalization continually occur within society, academic libraries can position themselves as agents for social justice via the presence and content of dei statements. in addition to social justice and student demographics, professional values, outlined in the american library association’s bill of rights, demonstrate the need for academic libraries to adequately serve non-white students.3 this article examines the dei statements on academic library websites and examines the presence, or lack thereof, and content of these statements to address the following research question: how do dei statements on academic library websites contribute to the construction of institutional value of diversity, equity and inclusion? information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 2 literature review literature regarding dei in academic libraries is plentiful.4 in addition to abundant scholarly research, the association of college and research libraries (acrl) addressed diversity via the “diversity standards: cultural competency for academic libraries,” while equity, diversity and inclusion are part of acrl’s timeless core ideology.5 the association of research libraries (arl) has similarly addressed diversity via the spec kit 356: diversity and inclusion, which compiled information regarding recruitment and retention of minority librarians, strategies for fostering inclusive workplaces, and diversity programs and assessment.6 additionally, the american library association (ala) announced the formation of a joint task force to create a framework for cultural proficiencies in racial equity.7 despite ample research and professional attention to dei, surprisingly, no studies have explicitly examined academic library dei statements and few studies have examined diversity content on library websites. academic libraries and dei statements examining website diversity content, mestre reviewed 107 arl member websites for the presence and visibility of diversity content.8 employing content analysis, mestre found that diversity language which focused on ethnic and racial diversity, particularly for black, latinx, native americans, and asian americans, was most included in a strategic plan (37%, n=39) and in a values statement (27%, n=29). member sites that included diversity in a mission (16%, n=17), vision (14%, n=15) or diversity (13%, n=14) statement were less frequent. generally, across types of diversity-related links and information, diversity content was limited on the arl sites and, when present, was often difficult to find, situated deeply within a website behind multiple layers, or requiring a site search to locate. academic library mission statements expanding the scope to include mission statements yields literature that examines communicating purpose. salisbury and griffis examined the presence and placement of mission statements on 113 arl websites.9 operating under the principle that considers website content as hierarchical (e.g., the most important information is most visible), the authors documented the number of steps necessary to reach the library’s mission statement. eighty-four percent (n=95) of library websites contained a mission statement and 3.5% (n=4) of libraries contained a direct link from the homepage. the authors identified a visibility issue, as mission statements on 14% (n=16) of websites required one click to access, but only four were clearly labeled as mission statements. despite this issue, salisbury and griffis found that mission statements were available in two steps or fewer in over 60% (n=72) of libraries. the authors’ findings indicate that academic libraries acknowledge the need to make their mission statements more visible to various stakeholders. academic libraries are responsible to the institutions within which they are situated, making their institutions a primary stakeholder. wadas employed discourse analysis and compared library and institutional mission statements from 44 colleges and universities and found 14 (31.8%) institutions, “showed a discernable degree of agreement between the college or university and library mission statements,” while the remaining 30 showed none.10 like salisbury and griffis’ finding regarding the lack of explicit labeling, wadas also identified a labeling inconsistency regarding the information in, and purpose of, each statement type. wadas’ analysis also identified a prevailing sense of vagueness across college/university and academic library mission statements, further contributing to confusion regarding statements’ purpose and intended messages.11 information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 3 mission statements, strategic plans and diversity: content analyses wilson, meyer, and mcneal examined institutional mission statements and other diversity-related content on 80 websites of institutions of higher education in the united states.12 fifty-nine (75%) referenced diversity in their mission statements and 52 (65%) had a separate diversity statement. of these statements, wilson et al. found most diversity references fell into two areas: population demographics (student body racial or ethnic composition) and cultural vitality (incorporating various cultures within the campus community). of the 59 institutions that referenced diversity in the mission statement, 63% were related to changing student demographics, while 55% referenced cultural diversity. furthermore, less than 10% of the statements included language that fell into both categories, indicating institutions conceptualized diversity in one area or the other. in addition to formal mission statements, wilson et al. found that 52 (65%) of the institutions contained other diversity content. given these findings, the authors state their disappointment in the 25%–35% of institutions that did not include diversity content in official, primary statements. recognizing the rapid developments affecting the lis field, saunders employed content analysis and examined the publicly available strategic plans of 63 acrl institutions.13 saunders’ analysis indicated that while 40 (63.5%) libraries alluded to institutional mission, goals, or strategic plan to some degree, only 17 (27%) made explicit connections, results similar to wadas’ findings.14 regarding specific content, saunders categorized themes into three tiers: major emphasis (>75% of strategic plans), second tier, and other areas of emphasis. saunders’ analysis revealed that strategic plan diversity content was a second-tier issue related to library staff. saunders found the term diversity was used in two ways: to refer to expertise, skills, and abilities; and to delimitate demographic characteristics, including ethnicity, nationality, or language.15 like wilson et al., saunders’ findings demonstrate academic libraries’ recognition of the importance of diversity in higher education.16 methodology this study employed content analysis and examined uborrow consortium members’ library websites (see appendix a for a list) for the presence and content of dei statements. uborrow is an interlibrary loan service comprised of big ten academic alliance members, plus the university of chicago and the center for research libraries, in which “users at member institutions are granted access to the collective wealth of information of the entire consortium.”17 uborrow members leverage individual campus resources to collaboratively assist the academic pursuits of students and faculty of each institution via the expedited sharing of resources. these libraries were chosen as a representation of a model consortium and are a reasonable focus for examination. content analysis is a research technique for making replicable and valid inferences from texts or other forms of contextually based data. it allows for data analysis “in view of the meanings, symbolic qualities, and expressive contents they have and of the communicative roles they play in the lives of the data’s sources”.18 content analysis provides a foundation for understanding how messages and meanings are constructed. as such, content analysis is appropriate to analyze the content and meanings of dei statements on uborrow websites. additionally, this study utilized multimodal theory, particularly lemke’s hypermodality and three communicative acts: organizational, presentational, and orientational.19 examining dei statements as multimodal texts allows for the analysis of meaning making and construction across information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 4 each type of act. just as users make meanings across sentences, paragraphs, and pages, users likewise make meanings from the ways in which they interact with digital information.20 the organizational aspect provides a way to examine the spatial arrangement of library websites, for example, libraries that dedicate entire webpages to dei statements or those in which these statements share pages with other content. content analysis provides a way of examining the presentational aspect of information, the ideational content of texts, in this case how dei statements are presented on uborrow websites. content analysis also provides a way to examine the orientational aspect, which indicates the nature of the communicative relationship, via exploring how libraries establish relations with whom they are communicating, for example, how the presence of dei statements positions libraries as conscientious entities engaged in the promotion of diverse and inclusive environments. i examined each uborrow member website for an explicit dei statement. informed by previous literature, i created an excel spreadsheet and entered data from each institution including: institution name, library website url, dei statement (yes/no), homepage link (yes/no), dei statement url, and notes following a standardized process. first, i recorded the library’s homepage. next, i searched the homepage for a dei statement link. if found, i indicated the presence in the yes/no columns and recorded the url. only direct links to library dei statements were marked as yes in the homepage link column. if no homepage link existed, i searched the library websites using the following terms: diversity, equity, and inclusion. when it was difficult to locate dei statements, i utilized the chat feature or e-mailed library administrators to ensure i was not overlooking relevant information. i conducted an initial search in july 2020 and a subsequent search in november 2020. no changes to explicit dei statements occurred. i conducted a followup search in april 2021. in the intervening months, one major change occurred on the university of minnesota libraries website. implications of this change are discussed below. once dei statements were identified, i examined the pages on which they were located. first, i examined page organization. in this step, i noted if the dei statement was the sole content on a page. if not, i noted the accompanying content. this analysis focused on lemke’s traversals, or the varied paths available to users in their search and navigation of websites.21 second, i analyzed dei statement content and identified the ways libraries presented their statements. this step included an examination of the language used in the dei statement. third, i expanded upon the presentational analysis and considered the ways dei statement content oriented the library toward users by exploring how statement language contributed to portraying the library in a certain way. this analysis focused on two areas: library-centered language common across statements and social justice language, which a subset of libraries’ dei statements employed. limitations uborrow is a single 16-member library consortium. further research of similar consortia or library associations would contribute to the study’s limited size. this study focused on explicit dei statements, thereby excluding other forms of dei content (e.g., announcements, marketing material, events). further research employing a broader view of dei content on academic library sites would also contribute to this study’s findings. finally, this study represents library websites during a snapshot in time. findings and analysis twelve (75%) uborrow member websites had an explicitly titled dei statement in november 2020 and 13 had an explicitly titled and labeled dei statement as of april 2021 (see table 1). in information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 5 november 2020, the university of minnesota had a clearly defined statement; however, this statement was untitled, and its location was unique among websites during the initial search. initially, this statement was not considered an explicit statement due to the lacking title, the implications of which are discussed in detail below. however, between november 2020 and april 2021, the university of minnesota libraries updated their homepage to include a link to a clearly defined and labeled dei statement, which university librarian and dean of libraries lisa german approved on february 1, 2021. for this reason, the university of minnesota libraries website receives unique discussion in the analysis that follows. three additional consortium members did not have an explicit dei statement. table 1. uborrow member libraries and the presence of dei statements institution explicit dei statement (y/n) university of chicago yes center for research libraries no university of illinois at urbana-champaign yes indiana university yes university of iowa yes university of maryland yes university of michigan yes university of minnesota no (fall 2020) yes (spring 2021) michigan state university yes university of nebraska yes northwestern university no ohio state university yes penn state university yes purdue university no rutgers university yes university of wisconsin madison yes while 12/13 of the 16 uborrow members contained an explicitly labeled dei statement, all member institutions addressed dei in some form, which included libguides, links to library resources, library events, and statements responding to specific societal events. however, the degree to which additional dei content prominent varied, with some content buried deep within library sites, as mestre’s work indicated.22 dei statement analysis: organization, presentation, and orientation the following section presents the descriptive analysis of the findings utilizing content analysis and lemke’s organizational, presentational, and orientational communicative aspects.23 analysis focused on questions about how the organization and presentation of dei statements contributed to the construction of meaning, the content of dei statements, and how content is oriented toward users in ways that position academic libraries as conscientious entities via their dei statements. organizational aspect of dei statements the organizational aspect of communication is instrumental and organizes and composes content in such a way that it is coherent and cohesive.24 organizational meanings have practical consequences, as the example of the university of minnesota’s library website demonstrates. information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 6 unique among uborrow sites as of november 2020, the university of minnesota libraries’ website contained a clearly focused, although untitled, dei statement. this statement is accessed via the about option on the homepage’s menu (see figure 1), which includes dropdown links to library policies, library overview, and the untitled dei statement. figure 1. the university of minnesota libraries’ homepage (november 2020). the statement’s placement is problematic for several reasons. first, the statement is easy to overlook. the researcher and a library staff member who responded to the researcher’s query via library chat both overlooked the statement. only when a third staff member was consulted did the identification of this statement occur. secondly, lemke discusses the affordances of hypertext and the many ways users can navigate websites, calling possible paths traversals.25 among the most basic is the visual-organizational traversal, which considers how webpage composition guides users’ eyes across the page. in this instance, the links are a call to action and signify to users that clicking on a link will transport them to a page with more information. static text on a webpage does not offer the same affordance. as a block of text located next to two panes of links, the statement is static, passive, and non-interactive, contributing to the ease with which users can overlook the statement. finally, this statement did not appear in the results of a library site search for the terms diversity, equity, or inclusion. given the various ways users can transverse a website, including actively searching for information, the lacking title makes this statement difficult to locate via scanning and searching. in users’ traversals of websites, two common approaches, identifying links or actively searching for desired information, are not applicable in locating the university of minnesota libraries’ dei statement. in the intervening months, between november 2020 and april 2021, the university of minnesota libraries website was updated to include an explicitly titled and labeled dei statement, available via a link from the homepage, prominently located in the upper right quadrant between the menu bar and hours and locations information (see figure 2). information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 7 figure 2. the umn libraries’ homepage (april 2021). this statement, written by the university libraries’ diversity, equity, and inclusion leadership committee, was approved on february 1, 2021. presented on a standalone page, this statement is similar to those of eight other uborrow consortium members, which are discussed in the next section. organization: stand-alone dei statements of the websites that contained explicitly labeled dei statements, eight libraries dedicated an entire page to the dei statement (nine including the umn libraries update). examination of these webpages revealed similar page titles, with variance according to the terms included. some page titles only included diversity, while others included diversity, equity, and inclusion. the university of michigan was unique as it also included accessibility. the relative consistency across these titles contributes to less frustrating and confusing user experience. clear and descriptive titles provide a positive experience for users accessing pages with an assistive screen reader. logistically, clear titles amplify page presence on searches conducted via google or other search engines. in addition to webpage titles, examination of the eight/nine pages revealed a relatively similar page organization and structure. each page contained headings that included some or all the terms diversity, equity, or inclusion. the pages were text heavy, with the university of nebraska and penn state university the only two whose pages included visual representations of diversity (i.e., images containing multi-racial groups). furthermore, the detail level of libraries’ dei statements were relatively consistent across the eight/nine webpages. while the page titles, organization, and detail of dei statements were similar, differences existed in the amount of additional dei content. for example, along with their dei statement, the university of maryland libraries’ diversity page defined diversity, an equitable environment, and inclusion. the university of michigan library followed their explicit dei statement with information relating the statement to the library’s collections, services, spaces, and people. other library webpages did not contain as much other on-page information. for example, rutgers university libraries links to various dei resources, which was another common trait (see figure 3). although clicking links requires additional steps to reach dei content, the presence of links is significant in consideration of lemke’s traversals. information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 8 figure 3. rutgers libraries’ diversity homepage with dei links. of the many types, a common organizational traversal is what lemke terms cohesive, in which “each element is an instance of some general category, and therefore with some thematic and/or visual similarities to the others, and as we catenate them we are cumulating toward an exhaustive exploration of the category”.26 the links on the rutgers university libraries’ diversity page allow users to traverse the library’s dei content, along with institutional dei content, as several links direct users to diversity pages external to the library. these links serve as calls to action and require users to click for more information. associated to dei content via the categorical connection, these links allow users to fully explore and expand upon the information found on the library’s dei statement page, allowing users to create their own meaning of library commitment to dei. user creation of meaning is in opposition to the library making this decision for the user, as when dei statements are placed on pages with other content, as is the case in four uborrow member websites. organization: shared dei statements unlike the libraries that dedicated a page to dei statements, variety exists in the page titles of the four libraries on which dei statements share pages with other content. dei statements are available via the about section of the library’s website, while of these, two are further couched on administration pages. the pages on which dei statements shared space exemplify mestre’s finding that dei content situated deeply within a website are difficult to locate.27 furthermore, the location of dei content is not entirely intuitive, making a user’s traversal to locate desired information less cohesive. michigan state university’s (msu) dei statement is found on the information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 9 library’s strategic plan page. rather than in a single statement, dei content is spread across the library’s strategic plan, including an inclusivity statement; a vision statement; and diversity, equity, and inclusion strategic direction (see figure 4). also, unlike the pages singularly devoted to a dei statement, msu’s strategic plan page was comparatively static with no links to other library or institutional dei content. the lack of links does not allow users to traverse msu’s site for dei content as easily due to the page’s static nature, making it difficult for users to, “construct a traversal which is more than the sum of its parts.”28 in this way, msu constructs the meaning of their commitment to dei via the limitations and restrictions on users’ interaction opportunities with the page on which their dei content is situated. figure 4. michigan state university libraries’ diversity content as part of strategic plan. organization: homepage links homepage links to dei statements were present on seven (58%) library homepages. when present, homepage links were located at two locations: in the menu or page footers. additionally, two levels of clarity existed regarding homepage links, as some sites contained an explicitly labeled link, while others required a two-step process to access the dei link. for example, the information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 10 university of iowa and penn state university libraries each had a clearly labeled link to their dei statement available via a single click on their library homepages. contrastingly, michigan, maryland, nebraska, ohio state, and rutgers all required users to first navigate a menu bar to find a link to the library’s dei statement. this two-step process requires more time and effort, whereas direct links require one less step. however, the direct link’s location on the university of iowa’s library homepage is located in the footer (see figure 5) and penn state university’s direct dei link is located near the bottom of the page, requiring users to scroll through entire pages. although requiring an extra step, libraries with a menu link at the top of the homepage, such as the ohio state university (see figure 6) do not require scrolling. a tradeoff exists between page location and number of steps to locate a link to the library’s dei statement when a homepage link is present. regardless of the homepage location, the presence of links to dei statements provides relatively easy access, making a user’s traversal to these statements relatively effortless and straightforward. figure 5. university of iowa libraries’ homepage dei statement footer link. figure 6. the ohio state university libraries’ homepage dei statement menu link. presentational aspect of dei statements lemke defines presentational meanings as those that present some state of affairs, which are construed from connections among processes, relations, events, participants, and circumstances and is significant for institutional purposes.29 users see the product of these actions that result in public dei statements. the discussions, meetings, efforts, and decisions that contribute to dei statements on library websites are concealed. the presence of dei statements represents the hidden work necessary for their creation, making dei statement content the library’s presentation of commitment to diversity, equity, and inclusion. information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 11 presentation: vague language and diversity conceptualizations examining the content of the 12/13 libraries with an explicit dei statement revealed these statements are frequently vague. many statements do not include specific language identifying what diverse means or who is in-/excluded. for example, rutgers university libraries’ dei statement states, “the libraries advance and promote diversity in all its forms” without describing, defining, or providing diversity examples.30 additionally, rutgers libraries endeavors “to create a welcoming workplace that reflects and supports the many populations and programs of the university with which we engage [emphasis original].”31 again, no definition indicates who the many populations includes. similarly, vague language produced an inconsistency regarding to whom dei statements were directed, with many, but not all, statements including faculty and staff. indiana university’s statement represents the later, stating, “iu libraries esteems diversity of all kinds […] to support students from diverse socio-economic backgrounds and foster a global, diverse inclusive community… in addition, the libraries commits to diversifying its own staff to reflect a diversity of perspectives and backgrounds [emphasis original].”32 including library faculty and staff acknowledges the potential significance of having a diverse and representative workforce, but still vaguely addresses the issue. unlike many dei statements which vaguely conceptualize diversity, the university of maryland libraries includes in its definition of diversity “race, ethnicity, nationality, religion, socioeconomic status, education, marital status, language, age, gender, sexual orientation, cognitive or physical disability; and learning styles” while noting diversity is not limited to these categories.33 similarly, the university of iowa libraries “welcomes and serves all, including people of color from all nations, immigrants, people with disabilities, lgbtq, and the most vulnerable in our community.”34 while still broad, and with language to cover additional conceptions of diversity, these statements’ explicit mention of various groups is unique among uborrow members’ dei statements. presentation: library-focused language continuing the broad conceptualizations of diversity, the university of chicago libraries’ statement includes an inward focus, which asks library users to consider their own positions and backgrounds: “we encourage open and honest discussion, reflect on our assumptions, and actively seek viewpoints beyond our own … and respect the uniqueness that we each bring to our shared endeavors.”35 this statement asks library users to actively challenge their own assumptions, values, beliefs, and views. however, the statement does not include active language regarding the necessity to prepare for challenging and difficult conversations and interactions. furthermore, the general conceptualization of these interactions with diversity makes it difficult for individuals to prepare for concrete situations in which one may encounter challenging, uncomfortable, or difficult conditions. utilizing lemke’s presentational aspect of communication, which considers processes, relations, events, participants, and circumstances to create and present a state of affairs, demonstrates that uborrow member libraries are vague in their dei statements, which the university of illinois at urbana-champaign (uiuc) exemplifies in their recognition of “diversity as a constantly changing concept. it [diversity] is purposefully defined broadly as encompassing, but not limited to, individuals’ social, cultural, mental and physical differences.”36 dei statements, as representative of academic libraries, present these institutions as attuned to larger social issues and the difficulties of making sweeping, definitive statements regarding diversity, when the term itself is, as the uiuc statement indicates, evolving and contested. the challenges this creates for library information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 12 administrators, and the hidden work that contributes to the creation and presentation of dei statements, is invisible in the end product, yet informs the content of these public statements. orientational aspect of dei statements orientational meanings establish relations between those who are communicating. these meanings communicate point of view, attitudes, and values.37 dei statements demonstrate libraries’ willingness to engage with and address dei issues, as well as, in some cases, combating racism and discrimination. analyzing the content of these statements produces insights into how statements orient libraries to their audiences. the vague and general language of many library dei statements creates a sense of detachment between libraries and users. conceptualizing diversity using vague language in an exchange between library users and a library dei statement orients the library in an abstract, immaterial way. using vague, broad, and ill-defined language makes no concrete demands of users. additionally, many dei statements are written in library-centered language, which positions the libraries at the center and users as peripheral. for example, the university of nebraska’s statement begins, “the university libraries creates and fosters inclusive environments for teaching, learning, scholarship, creative expression and civic engagement.”38 in this instance, the onus is on the libraries and what they can do to address issues of diversity, equity, and inclusion. the statement continues, “libraries staff members are empowered to provide an array of library services, collections, and spaces to meet the diverse needs of students, faculty, and researchers.”39 again, the library self-promulgates their efforts to address dei issues and ignores users’ contributions to positive, inclusive, and equitable environments. the university of nebraska libraries’ statement is not unique in the use of library-centered language, as such language is common across uborrow members’ dei statements. less vague and user-centered language would make library dei statements more humanizing, valuable, and contribute to the inclusive environments these statements espouse. orientation: anti-racism and social justice language some libraries’ dei statements make explicit mention of larger social issues and actively position themselves as social justice advocates, particularly anti-racism. the university of wisconsin – madison libraries are “dedicated to the principles and practices of social justice, diversity and equality and … commit ourselves to doing our part to end the many forms of discrimination that plague our society.”40 the penn state university libraries’ statement includes a commitment to “disrupting racism, hate and bias whenever and wherever we encounter it.”41 the university of michigan library “actively work[s] to ensure that tenets of diversity and antiracism influence all aspects of our work.”42 these statements present the libraries as cognizant, responsible, and socially aware entities. in these statements, the libraries’ employment of social justice discourse demonstrates nonneutrality. the university of wisconsin – madison libraries’ statement recognizes its place within society and the continual legacy of discrimination which tangibly affects current students. identifying social discrimination as a “plague” implies a solution via targeted, collective efforts to “further and enable the opportunities for education, benefit the good of the public and inform citizens.”43 similarly, the ohio state university libraries are guided by priorities “which facilitate, celebrate and honor diversity, inclusion, access and social justice.”44 embracing an active stance against social discrimination and positing the libraries as proponents of social justice utilizes the libraries’ dei statement as a tool to combat these injustices. semantically, dei statement text information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 13 offers information to users. statement content demonstrates libraries’ willingness to address dei issues institutionally and within society. the text demonstrates the libraries’ desire to combat injustice and the importance they place in doing so. additionally, in linking dei statements to social justice issues, libraries make demands of users. while still employing library-centered language, these statements provide a call to action via their direct acknowledgement that the libraries’ actions are a part of larger, collective efforts in the continual struggle against social injustices. lack of explicit dei statements as the analysis shows, the ways in which academic libraries organize, present, and orient themselves via their dei statements contributes to the construction of institutional value of, and commitment to, diversity, equity, inclusion. but what about libraries who do not have an explicit dei statement? in the united states context, given the attention to diversity, through black lives matter and other social movements advocating for social justice, it is surprising that four uborrow members do not have explicitly labeled dei statements on their websites. orientationally, the absence of an explicit dei statement suggests a lack of concern and consideration on behalf of libraries, as well as seemingly being out of touch with broader social contexts in which racial disparities persist. a clear dei statement, however, is a single piece of a library’s online presence. academic libraries can organize and present dei content on their websites in other ways, as all uborrow members did, even if an explicit statement was lacking. for example, the purdue university libraries have a diversity, inclusion, racism and anti-racism resources library guide, which acts as a one-stop shop for dei-related material. additionally, this guide contains a statement from the dean of libraries, dated june 2, 2020, condemning and making a collective call to action to address systemic racism. given this statement, while acknowledging the bureaucratic mechanisms in place that may slow the creation of an explicit dei statement, the question remains: if “enough is enough” as the statement claims, why have the purdue libraries not taken swift action to expedite the bureaucratic process? purdue university libraries are working behind the scenes and have created a council on equity, inclusion and belonging, as well as creating a new strategic plan in which “edi [equity, diversity and inclusion] is much more prominent in the current draft of that plan than in previous ones.”45 similarly, northwestern university does not, as of this writing, have an explicit dei statement. however, minimal diversity language is present in a public-facing welcome message on the library’s about page stating, “your library serves the diversity of the northwestern community.”46 furthermore, minimal diversity language appears in the internal strategic plan, 2019–2021, which includes a commitment to “responding to the vibrant diversity of our campus community.”47 additionally, recent conversations regarding racism, diversity, and social justice among library leadership have spurred the creation of a formal edi program at the institutional level.48 examining the situation at northwestern university revealed a look into the hidden work required to create and present dei content and an explicit dei statement, demonstrating the institutional significance of the presentational aspect of communication. discussion and implications the descriptive analysis presented in this study provides a foundation for closer analysis and future research, with potential avenues suggested below. this analysis also illustrates issues with the way in which dei statements are presented on academic library websites, which, given the pervasive whiteness of academic librarianship, affects academic librarians, staff, and the students information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 14 they serve. following lemke’s treatment of organizational meanings as primarily instrumental, the following section discusses presentational and orientational implications of dei statement content.49 academic libraries are an integral component of the institutions within which they are situated. their physical and digital spaces, services, and resources are critical to students’ academic success and faculty research. academic libraries also contribute to larger institutional dei initiatives. while an examination of institutional dei statements is beyond the scope of this study, institutional mission and vision statements also address diversity, equity, and inclusion. although many institutions have implemented specific diversity statements, wilson, meyer, and mcneal identified diversity content on institutional websites as being limited.50 given the changing demographics of higher education in the united states, the significance of dei to academic institutions and libraries will continually increase. if the purpose of mission and diversity statements is to reflect institutional priorities, as wilson and colleagues argue, the presence, or lack thereof, and content of these statements indicates the extent to which institutions value diversity, equity, and inclusion.51 presentational implications of dei statements in the context of the present study, that all uborrow member libraries’ websites engaged in some ways with dei content demonstrates the value they place on diversity, equity and inclusion. however, that only 12/13 of the 16 sites contained explicitly titled dei statements demonstrates more concerted effort is required if these libraries are to truly demonstrate their commitment. despite other dei language, northwestern university, a member of the 2020 acrl diversity alliance, does not have an explicit, public-facing dei statement, which demonstrates the many ways academic libraries are involved with diversity initiatives. while academic libraries may have internal policies that guide practice, that these policies, if they exist, are not public does not contribute to the construction and dissemination of the libraries’ message indicating their commitment to diversity, equity, and inclusion. the lack of a publicly facing statement, whether intentional or not, contributes to the message that the library is not fully committed to diversity, equity, and inclusion. in this vein, further exploration of diversity content and statements, at the institutional and library levels, is necessary to expand upon the findings of the present study regarding the messages dei statements send. qualitative studies could investigate the working cultures of academic libraries and explore internal mechanisms that contribute to the creation of public facing statements and how these mechanisms operate. lemke argues that presentational meanings are typically uncritical due to the presupposition of institutional hierarchies and roles, which minimize threats to the status quo, making this avenue especially fruitful from a critical or decolonizing framework.52 other opportunities for further research include quantitative content analysis of diversity statements, which could reveal specific words, terms, and phrases that institutions and academic libraries use to shed light on how these entities conceptualize dei. research examining users’ perspectives of academic library dei content is necessary to explore the ways in which libraries’ messages are received. orientational implications of dei statements examining uborrow members’ dei statements revealed the frequent employment of librarycentered language. framing the statements in this way places responsibility to create inclusive, equitable and welcoming environments on academic libraries, librarians, and staff. if the onus is information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 15 on academic libraries, as this dei statement language suggests, those who staff libraries are required to appropriately serve diverse students. as such, practical considerations of staff training regarding cultural competence is of paramount importance, which the university of michigan recognizes as they “encourage all library staff to participate in diversity-focused professional development and training activities.”53 while training and professional development opportunities are of limited utility, as cultural competence, cultural humility, and a diversity mindset cannot be acquired in one-off sessions, setting a pervasive atmosphere establishes institutional library value of diversity, equity, and inclusion. furthermore, hiring and retaining staff representative of student demographics is critical as doing so is one way academic libraries can demonstrate evidence of their values placed on diversity. that librarianship has traditionally been a white profession, as 86.7% of ala members selfidentified as white as of 2017 and 86.1% of higher education credentialed librarians were white as of 2009–2010, exacerbates the need for representative library staff.54 however, recruiting and hiring diverse staff is challenging as the number of visible minorities in academic librarianship has remained stagnant.55 retaining academic librarians and staff of color is a separate challenge, as institutional and library environments, expectations and research output are all explicit barriers, while internal pressure and time management constraints are implicit barriers.56 academic librarians and staff of color are subject to racial microaggressions perpetrated by unaware nonminority colleagues, an issue that permeates higher education, particularly at historically white institutions (hwis).57 these environments contribute to individual stress and fatigue for faculty of color.58 a history of what mehra and gray label white-ist trends in lis, an amalgamation of practices that symbolize, “racist connotations and racism in lis that is part of its historical evolution and development in the united states” affects librarians and staff of color.59 at the societal level, hate crimes are a continual issue in the united states.60 academic library dei statements were not created to directly address grand social issues. however, some dei statements included a social justice call to action. while not all dei statements contained such language, those that did not still made a commitment to supporting diversity. academic libraries’ dei statements identify the scope of available services and demonstrate libraries’ collective attempt to provide equitable spaces for all campus community members. while these statements occasionally align with institutional diversity statements, institutional responses to bias and discrimination provide insight into other ways institutions craft an identity.61 especially at hwis, these responses typically include demonstrating a professed commitment to dei, acknowledging actions to prevent future instances, establishing a protocol in the event an incident occurs; and addressing the issue and removing the institution from the perpetrators’ actions.62 academic library dei statements that simply state a commitment to diversity and inclusion without actively promoting change, which is lacking in the vague, library-centric language common to these statements, is a typical, though not emphatic, stance. this passive stance demonstrates the need for critical analysis of orientational meanings. such critical analysis allows for the examination of scrutinization of the actors and processes involved in dei statement creation, presentation, and messaging. such an examination offers an avenue to hold institutions accountable for their words and dei statements. future research that examines academic libraries’ responses to specific incidents of bias and discrimination could provide further insight into internal processes that lead to the public display of academic libraries as change agents. additional research could examine individual academic librarians and staff to interrogate the congruences or dissimilarities of individual and institutional practices regarding engagement with dei initiatives. information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 16 conclusion examination of uborrow members’ websites revealed that 12/13 of 16 sites contained explicitly labeled dei statements. although not all members’ sites contained an explicit statement, every library engaged with dei content in some way. among the 12/13 sites that contained an explicit dei statement, distinctions existed regarding statement organization. eight/nine libraries dedicated an entire page to their dei statement, while four members’ statements shared a page with other content. organizationally, the pages containing dei statements were similar with textheavy pages common across the websites. presentationally, dei statements serve as publicly facing representations of university libraries. the most telling insight into the presentational aspect of communication was revealed in an analysis of the sites that did not contain explicit dei statements, as this analysis examined the hidden work that is necessary in dei statement creation. orientationally, vague and library-centric language distances academic libraries and positions them as abstract entities. those libraries whose dei statements employed social justice language made more concrete demands of users. while explicit dei statements comprise only a portion of academic library dei content, an analysis of these statements revealed the ways in which they contribute to academic libraries’ construction of value of, and commitment to, diversity, equity, and inclusion. this analysis demonstrated how the presence, or lack thereof, of dei statements positions libraries as conscious entities operating within institutional and social contexts that both restrain and encourage promotion of diversity, equity, and inclusion. that the university of minnesota libraries updated their homepage to include a link to a newly constructed dei statement during the months between the first and second examination of uborrow consortium members’ websites in this study indicates the significance and value institutions place on dei initiatives. academic libraries, as entities that operate within institutions in the social context of historical racism, discrimination, and marginalization in the united states, are not immune to the consequences of these enduring legacies. despite current and ongoing efforts, this analysis revealed that much work and dedication is yet required in the continual engagement with dei initiatives. information technology and libraries december 2021 diversity, equity & inclusion statements on academic library websites | ely 17 appendix a: uborrow member institutions university of

demystify false impressions about strategies; how strategies play a role in the planning and delivery of library services; broad categories of library strategies that can be used; and identification of new ways to communicate the impact of strategies to patrons. as the author states in the introduction, the focus of libraries has moved from collections to encompass the arena of change itself. finding strategies to enable operation in a fluid environment can mean the difference between relevance and irrelevance in today’s competitive information marketplace. the book is divided into three major sections: (1) what is a strategy, and the importance of having one; (2) the value of and options for strategic planning; and (3) the need to monitor and update strategies. the first four chapters make up the first section. chapters 1 and 2 go through the semantics and the need for strategies, as well as the realities and limitations of strategies. chapter 3 provides brief introductions to schools of strategic thought. these include the design school, the planning school, the positioning school, the entrepreneurial school, the cognitive school, the learning school, the power school, the cultural school, the environmental school, and the configuration school. chapter 4 introduces types of strategies: operational excellence, innovative services, customer intimacy, and the concept of strategic options. section 2 consists of chapters 5 through 8 and provides information on what strategic planning is, what its value is, process options such as planning alternatives and critical success factors, and implementation. section 3, comprised of chapters 9 and 10, focuses on the culture of assessment; monitoring and updating strategies; and tools available for managing the library. two appendixes are provided: one containing sample library strategic plans, and another with a critique of a library strategic plan. overall, the book is very straightforward and understandable, with numerous illustrations, process workflows, and charts. i found the information very interesting and useful, and the final section on assessment and measurement of strategic planning is essential for libraries to implement and monitor in today’s marketplace. the various explanations related to schools of strategic thought were especially helpful. this book should be read by every library manager and director involved in strategic planning and process.—brad eden, associate university librarian for technical services and scholarly communication, university of california, santa barbara ebsco cover 3 lita 107, 111, covers 2 and 4 index to advertisers facing what’s next, together lita president’s message facing what’s next, together emily morton-owens information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.12383 emily morton-owens (egmowens.lita@gmail.com) is lita president 2019-20 and the acting associate university librarian for library technology services at the university of pennsylvania libraries. when i wrote my march editorial, i was optimistically picturing some of the changes that we are now seeing for lita—while being scarcely able to imagine how the world and our profession would need to adapt quickly to the impacts on library services as a result of covid-19. it is a momentous and exciting change for us to turn the page on lita and become core, yet this suddenly pales in comparison to the challenges we face as professionals and community members. libraries’ rapid operational changes show how important the ingenuity and dedication of technology staff are to our libraries. since states began to shut down, our listserv, lita-l, has hosted discussions on topics like how to provide person-to-person reference and computer assistance remotely, how to make computer labs safe for re-occupancy, how to create virtual reading lists to share with patrons, and how to support students with limited internet access. there has been an explosion in practical problem-solving (ils experts reconfiguring our systems with new user account settings and due dates), ingenuity (repurposing 3d printers and conservation materials to make masks), and advocacy (for controlled digital lending). sometimes the expense of library technologies feels heavy, but these tools have the ability to scale services in crucial ways—making them available to more people at the same time, available to people who can only take advantage after hours, available across distances. technologists are focused on risk, resilience, and sustainability, which makes us adaptable when the ground rules change. our websites communicate about our new service models and community resources; ill systems regenerate around increased digital delivery; reservation systems for laptops now allocate the use of study seating. our library technology tools bridge past practices, what we can do now, and what we’ll do next. one of our values as ala members is sustainability. (we even chose this as the theme for lita’s 2020 team of emerging leaders.) sustainability isn’t about predicting the future and making firm plans for it; it’s about planning for an uncertain future, getting into a resilient mindset, and including the community in decision-making. although the current crisis isn’t climate-related per se, this way of thinking is relevant to helping libraries serve their communities. we will need this agile mindset as we confront new financial realities. our libraries and ala itself are facing difficult budget challenges, layoffs, reorganizations, and fundamental conversations about the vitalness of the services we provide. my favorite example from my own library of a covid-19 response is one where management, technical services, and it innovated together. our leadership negotiated an opportunity for us to gain access to digitized, copyrighted material from hathitrust that corresponds to print materials currently locked away in our library building. thanks to decades of careful effort by our technical services team, we had accurate data to match our print records with records for the digital versions. our it team had processes for loading the new links into our catalog almost mailto:egmowens.lita@gmail.com information technology and libraries june 2020 facing what’s next, together | morton-owens 2 instantaneously. the result was a swift and massive bolstering of our digital access precisely when our users needed it most. this collaboration perfectly illustrates how natural our merger with alcts and llama is. as threats to our profession and the ways we’ve done things in the past gather around us, i am heartened by the strengths and opportunities of core. it is energizing to be surrounded by the talent of our three organizations working together. i hope more of our members experience that over the summer and fall, as we convene working groups and hold events together, including a unique social hour at ala virtual and an online fall forum. i close out my year serving as the penultimate lita president in a world with more sadness and uncertainty than we could have foreseen. we are facing new expectations and new pressures, especially financial ones. as professionals and community members, we are animated by our sense of purpose. while lita has been transformed by our vote to continue as core, the support and inspiration we provide each other in our association will carry on. lib-s-mocs-kmc364-20140601053338 two types of designs/ mcgee 203 book reviews the proceedings of the international conference on training for information work, rome, italy , 15th-19th november 1971, edited by georgette lubock. joint publication of the italian national information institute, rome and the international federation for documentation, the hague; f.i.d. publ. 486; sept. 1972, rome, 510 p. let's face it: there is something about any proceedings that elicits a very personal reaction in many of us: "here are papers that either, a) got their authors a trip to the conference city; b ) tell how we did good at our place; or c) unabashedly present h.b.i.'s( half baked ideas )." i personally like proceedings that have many papers under category c); such papers make me think ( or laugh ). the great majority of papers in these rome proceedings fall basically under category b), i.e.-'how we done it good,' and some quite obviously under a), i.e.-'have paper will travel'-well it was rome, italy, after all. however, there is a smattering of papers that fall under c), i.e.-h.b.i.'s. so for those interested in the topic, these proceedings offer among other things some food for speculative thought. for these other things let us start at the beginning. the contents consists of prefatory sections, one opening address, sixty-six papers, a set of twenty brief conclusions, three closing addresses, a summary of work at the conference, an author index, and a list of participants and authors' addresses. the papers are organized according to two major sessions: one on "training of information specialists" (nine invited and fortytwo submitted papers ) and another on "training of information users" (six invited and nine submitted papers ). the larger number of papers on training of specialists vs. training of users probably represents a good assessment of real education interests in the field. the conference was truly international: authors came from four continents, twenty countries and four international organizations. most represented were: italy as host country with fifteen papers, usa with eight, great britain with seven, and france with six papers. the concern for information science education is indeed worldwide; however, if the presented papers are any measure, such education is in big trouble, because one is left with the impression that information science education is in some kind of limbo: the bases, relations, and directions are muddled or nonexistent. but then isn't all contemporary higher education in big trouble, and in limbo? the conceptions of what information science education is all about differ so widely from paper to paper that the question of this difference in itself could be a subject of the next conference. it is my impression that the differences are due to a) widely disparate preconceptions of the nature of "information problems,'' and b) incompetence of a number of authors in relation to the subjects. accomplishments in some other field or, even worse, 204 journal of library automation vol. 5/3 september, 1972 a high administrative title does not necessarily make for competence in information science education. the proceedings offer a fascinating picture of information science education by countries and by various facets. it also offers frustration due to unbelievably unhygienic semantic conditions in the treatment of concepts, including a confusion from the outset of "training" and "education." the first business of the field should be toward clearing its own semantic pollution; such a conclusion can be derived even after a most cursory examination of the papers. my own choices for the three most interesting papers are: -v. slamecka and p. zunde, "science and information: some implications for the education of scientists;" (usa) -s. j. malan, "the implications for south african education in library science in the light of developments in information science;" (south africa) -w. kunz and h. w. j. rittel, "an educational system for the information sciences." (germany) the editing of the ptoceedings is exemplary; the editors and conference organizers worked hard and conscientiously. the proceedings also provide the best single source published so far from which one could gain a wide international overview not only of information science education but also of information science itself, including implicitly the problems the field faces. in this lies the main worth of the proceedings. t efko saracevic computer processing of library files at durham unive1·sity; an ordering and cataloging facility for a small collection using an ibm 360/ 67 machine. by r. n. oddy. durham, england: university library, 1971. 202p. £1.75. the task of the book is to guide the reader in the use of the lfp (library file processing) system developed by the durham university library. the lfp system orders items and prints book catalogs in various sequences for a small collection of items with the aid of an electronic digital computer. the system is batch with card input and printed output; the programs are written in pl/1. "the lfp system was designed to be flexible and easy to operate for small files , and is less suitable for files larger than 10,000 items because there are then other problems which it does not attempt to solve." (p. 10). the book fulfills its assigned task well; it is an excellent example of explanations and instructions for the personnel charged with the day to day operations for the particular system described. the book includes excellent introductory chapters on job control language, how computers operate, file maintenance, etc. outside of the durham university library, however, the book has little use except as a model of a well done operations guide. kenneth ]. bierman june_ital_fifarek_final president’s message: for the record aimee fifarek information technologies and libraries | june 2017 1 this is my final column as lita president. having just finished the 2016/17 annual report, i must admit i’m a little tapped out. over the last year i’ve written on the events of an ala annual and midwinter conferences, a lita forum, a new strategic plan, information ethics, and advocacy. even for an english major and a librarian that’s a lot of words. as i work with executive director jenny levine and the rest of the lita board to prepare the agenda for our meetings at annual, the temptation is to focus on all the work that is yet to be done. but with the end of school and fiscal years approaching, it is the ideal time to celebrate everything that has been accomplished over the last 12 months. first off, at some magical point during the year we completed the lita staff transition period. jenny has truly made the executive director position her own, and although she and mark beatty have more than enough work for six people, they are well on their way to guiding lita to a bright new future. with her knowledge of the inner workings of ala and her desire to make everything easier, faster and better, jenny is truly the right person for this job. next, we have a great new set of people coming in to lead lita. andromeda yelton is going to be a fabulous lita president. she is an eloquent speaker, has more determination than anyone i know, and is a kick ass coder to boot. bohyun kim has an amazing talent for organizing and motivating people, and as president-elect work wonders with the new appointments committee. our new directors-at-large lindsay cronk, amanda goodman, and margaret heller are all devoted litans who will be great additions to the board. i’m glad i get to work with them all in their new roles as i transition to past-president. and last but certainly not least we have started to make inroads on our advocacy and information policy strategic focus. the privacy interest group has already raised lita’s profile by supplementing ala’s intellectual freedom committee’s privacy policies with privacy checklists.1 a group of board members along with office for information technology policy liaison david lee king and advocacy coordinating committee liaison callan bignoli are working on a new task force proposal to outline strategies for effectively collaborating with the ala washington office. these are just the first steps towards a future in which lita is not only relevant but necessary. with all that hard work accomplished, it must be time to toast to our successes. i hope that everyone who will be at ala annual in chicago (http://2017.alaannual.org/) later this month will join us as we conclude our 50th anniversary year. sunday with lita promises to be amazing, with aimee fifarek (aimee.fifarek@phoenix.gov)

https://www.crowdrise.com/lita-50th-anniversary. being lita president during the association’s 50th anniversary year has been both an honor and a challenge. during a milestone year like this you become acutely aware of all of the hard work and innovation that was required for the association to thrive for half a century, and feel more than a little pressure to leave an extraordinary legacy that will ensure another fifty years of success. it’s a tall order, especially in an era of rapid political and societal change. but as i navigated through my presidential year i realized that i didn’t have to do anything more than ensure that people who already want to work hard for the greater good have a welcoming place to do just that. after fifty years, lita still has the thing that made it a success in the first place: a core group of volunteers committed to the belief that new technologies can empower libraries to do great things. the talented and passionate people i have worked with on the board, in the committee and interest group leadership, and throughout the membership are the best legacy that an association can have. now more than ever the people in libraries who “do tech” can be leaders in their communities and on the national stage. now more than ever it is lita’s time to shine. references 1.

event journey in 2020. this is our story. twitch.tv is the most popular video game streaming platform on the internet right now, but that does not mean it is the easiest to use or navigate as content creators. while the mistakes were many, you do not have to repeat them. in short, lessons learned over the past two years fell under four distinct categories, many of them interrelated or compounding one another: • physical space limitations and challenges migrating studio setups during various phases of the covid-19 pandemic. • complex decisions making audio and video equipment purchases. • our own familiarity with videogame streaming platforms and specialized software. • converting our in-person event policies and codes of conduct for virtual events. mistakes 001–135: picking the right time, place, and software we can say confidently that mistake #1 in your 500-mistake journey is pretending the library will strike gold with its first ever stream and achieve instant online success. we chose minecraft as our first videogame featured on twitch.tv. the cold reality is that real-world streamers who host thousands of viewers at one time are not building the interpersonal connections you are likely aiming for as a librarian. the second biggest mistake you’re likely to make while setting up a stream is in picking the right location. over the course of two years, in response to different levels of building access, we ended up moving our ad-hoc studio location a total of four times. each location posed its own challenges, and we learned more about what worked with every move. your streaming space should not only be distraction free, but also easy to adjust as needed, because your setup will change over time. picking the right av equipment for your stream is a gigantic topic, and the subject of infinite support forum threads and online discussions. the correct answer also largely depends on if you plan to stick with console game streaming, or pc, or some mixture of both. we can summarize by saying that to start off, you do not need the very best studio gear, and in fact , this thinking can lead to an artificial barrier that might result in more “tech debt” than necessary. you will end up spending a considerable amount of time troubleshooting strange quirks that were not there the last time you streamed, or with each new equipment purchase/upgrade.

while streaming on twitch.tv | markman, kimura, and wallner 2 mistakes 136–223: moderation tools and volunteers we have had to block a few bots, as well as tactfully defuse some loose-cannon streamsurfers by maintaining aggressive kindness in answer to their sarcastic questioning. overall, our moderating world has not been rocked in a way we weren’t prepared for, due to our thoughtfully crafted and transparent policy that was adapted from our patron code of conduct, trained teen volunteer moderators, and clear communication as a team. mistakes 224–301: the finer points of twitch.tv in addition to having had little experience playing video games in general, our stream host also had no experience with streaming. by design, kasper went into our first stream with only two guidelines for interacting with twitch viewers: don’t stop talking and be friendly. no one wants to watch someone silently play a game badly; it’s not engaging and it’s not fun. another part of using twitch that we did not account for until we were in the middle of the first stream is that the chat runs on a delay. this makes sense from a moderating point of view; you want to be able to catch inappropriate or spam comments. however, in terms of holding a conversation with the chat, it became a mental challenge to hold multiple threads of conversation at a time—all while playing—and all while narrating what’s happening on screen, and as people were typing to respond to what was just said or done. this process can be very overwhelming for twitch.tv hosts.1 imagine driving a car on the highway while also watching a movie of yourself, and then simultaneously holding a conversation with ten or more people in the back seat of this car at the same time. they’re not commenting on what you’re currently doing though, instead they’re making jokes about the on-ramp or stop light two miles back. it’s not impossible to juggle these tasks simultaneously, but as the host, it does require practice. mistakes 302–389: art is a process, just like the inevitable bugs you will find in your setup every time you change anything heed our warning! you can find a mountain of well-meaning online advice and tutorials about the best possible streaming setup and content strategy: much of this is outdated or aimed at a very specific subset of gamers. there is a cottage industry of media consultants and youtuber personalities that review hardware and share tips and tricks advice. your information literacy skills should not go to waste here! always consider the source. stream decks and keyboard shortcuts: what the twitch.tv pros get right if we could go back in time, there is one element to our stream setup that could have been integrated sooner, and that’s the stream deck by elgato (https://www.elgato.com/en/streamdeck). this extra desktop keypad is literally a game changer for usability—it is the peanut butter that smooths over all the ux cracks created by open broadcast studio (obs) and the chaos of chat interactions already discussed. this small hardware upgrade also makes onboarding new stream hosts much easier because there is no need to memorize keyboard shortcuts: the buttons on the stream deck can be customized to do exactly what they say they do (like mute audio, change screen layouts, or stop and start streaming). mistakes 390–499: do androids dream of electric animal crossing dream codes? what does twitch.tv outreach look like? we used social media to connect with other organizations doing similar work, such as the lgbtq+ youth space in san jose. we had worked with this group before the pandemic on some https://library.cityofpaloalto.org/library-policies/patron-code-of-conduct/ https://www.elgato.com/en/stream-deck

and wallner 3 pride programs for teens at the library, and so in 2020, when we saw on their instagram that they had a minecraft server open to the local community, our team eagerly jumped on this opportunity to collaborate with them. we had a minecraft stream; they had a minecraft server—could the stars be any more aligned? after some planning, one of the server mods joined us for a stream and gave us a tour of their server, which ended up being one of our most popular streams to date. conclusion: and what did we learn from all this? the final mistake (#500) is giving up. over the past two years we have hosted over 50 streams at https://www.twitch.tv/paloaltolibrary and can say confidently that not only was each virtual event unique, but also improved over time. we encourage more librarians to test out this mode of online outreach and practice your iterative design skills. video game streaming is not only fun for both the audience and hosts, but also a great way to connect with “extremely online” patrons of all ages. endnotes 1 to illustrate this problem in more detail: consider the events of our first very first stream, in which kasper’s dog saw a postal employee through the window while live on camera and reacted accordingly. this was one of the many reasons why moving our center of operations from the living room to the library was an upgrade.

writing for technical and professional journals by john h. mitchell. john wiley & sons, inc., new york, london and sydney, 1968, 405 pp. this book reprints, describes, summarizes or refers to every item in what has to be the world's largest scrapbook of material relating to professional publication. the last 240 pages (three-fifths of the total) include "sample" style guides from the ieee, management science, aibs, acs (including seven or eight pages of abbreviations used in chemical abstracts), aip, the gpo, nasa, the modem language association, the american mathematical society, the american medical association, the apa, the american sociological review, the american economic review, the hispanic american historical review, the nea, and sundry others. in almost every case, the excerpted or complete style guide is followed by an illustrative article. i would doubt that any other such compilation exists. the chapters which precede this anthology discuss more general aspects of writing for professional journals: design and approach, the collection, correlation, selection and anangement of data, and the . elements of journal articles. the text in these chapters is crowded with material of the most varied and unexpected kinds: disquisitions on logic, formal organization, outlining, interview techniques, information retrieval, the dewey decimal system, the ejc thesaurus, and much, much more. there is only one problem in all of this, but it is a· serious one, epitomized by the quotation from robert louis stevenson which mitchell uses as motto for his first chapter: "if a man can group his ideas, he is a good writer." this real treasury of reference material is all but inaccessible to the reader. titles of the five chapters are not very descriptive, and the index is not organized as a retrieval device. if one knows where in the book to look, he can find very useful information, but just leafing through the pages is neither efficient nor easy. it is made particularly difficult, in fact, by the striking lack of editorial judgment exercised in the design of the book. there is no differentiation between the author's comments and the examples and illustrations which he reprints (unless, as in some cases, the typography of the original has been reproduced). headings within chapters, where they exist at all, are confusing-and again, it is often difficult to determine whether they are part of mitchell's organization or part of some quoted work. as a result, it is hard to say who should buy this book and even harder to say how it might be used. professor mitchell, who "was elected teacher of the year by the students of the university of massachusetts" in 1965, is presumably able to make selections from the contents and to present them effectively in a classroom. perhaps the publishers might atone for 50 journal of library automation vol. 2/1 march, 1969 their abnegations of responsibility in preparing this book for the press by prevailing upon its author to write a supplementary, and much-needed, user's guide to its contents. a. ]. goldwyn computer peripherals & typesetting by arthur h. phillips. london, her majesty's stationary office, 1968. 665 pp. $28.80. the appearance of a comprehensive volume on computer composition is a boon to librarians as it comes at a time when progress with marc and other complex data bases calls for printing and other output capabilities which exceed those now commonly available with computers. recent advances in photocomposition technology now make possible printing of graphic arts quality at acceptable costs for certain types of com~ puter produced library publications, such as book and periodical catalogs whose basic input includes upperand lower-case and a full range of diacritical marks. with these advances librarians need no longer accept the limitations of character sets and image quality imposed by present line printers. a quality product is needed for outputs which are destined for publication. some pioneers have already made good use of this advanced technology to produce quality catalogs and lists; this book will help others to travel the same road. the volume is a comprehensive reference compendium of data on computer peripherals which is not otherwise available in convenient form. it gives special emphasis to the coding and keyboarding of alphanumeric texts and describes how the computer can be used for text processing with a typographic output. it also gives an appreciation of the problems involved and the techniques and equipment that are available to those who are preparing to enter this important field. the text is arranged in three sections. the first is an introduction to computer processing of alphanumeric data which is intended for printing in typographic quality. the second describes many types of computer peripherals and gives considerable attention to the various codes used for computer and printing equipment data input. the third section describes alphanumeric text composition and the available graphic arts composing equipment. the text is supplemented by many illustrations, diagrams, and tables plus an index and a glossary of terms. while much of the material in the volume will become outdated within a short time, a substantial portion of it is sufficiently basic to retain its value for a longer period. this handsome book is intelligently conceived and well-written by one of england's leading authorities on printing and ' computer typesetting. for anyone seriously interested in the subject the volume is essential and worth its price. richard de gennaro book reviews 51 coordinate indexing, by john c. costello, jr. rutgers series on systems for the intellectual organization of information, volume vii. edited by susan artandi. the rutgers university press, new brunswick, n.j., 1966. 218 pp. this paperback book is the result of ~ seminar meeting on coordinate indexing held april 28 and 29, 1966, under the sponsorship of the rutgers graduate school of library service. the volume consists of a detailed presentation of the subject by john costello of battelle memorial institute, followed by a discussion of the presentation by four panelists. the objectives of the book as given in the preface are: to offer a description, discussion, critique, and collection of facts and data on coordinate indexing as one of the systems which may be used to intellectually organize information contained in documents. basically an introductory description of the subject is offered. however, the principles of coordinate indexing are included so that the material has value for anyone interested in the topic. with examples offered primarily from metallurgy and engineering, the emphasis is on the handling of technical documents. about half of the presentation is devoted to input, with storage, searching, and output comprising the other half. discussion by the panel (dr. susan artandi, moderator; dr. charles l. bernier; dr. vincent e. giuliano; and dr. i. a. warheit) is not given verbatim, but summarized by the editor. although the table of contents is quite detailed,

1966. 219 pp. $6.00. this remarkable little book is rapidly becoming a classic in the field of information science. (note that it is now in its third printing.) it analyzes the concepts and problems of libraries of the future, "future" being defined as the year 2000. the book is the culmination of a two-year research project on the future of libraries sponsored by the council on library resources. the study was conducted by bolt beranek and newman, inc. between november, 1961, and november, 1963. the first part of this book describes man's interaction with recorded knowledge in what mr. licklider calls "procognitive systems." the author assumes man will be reacting to segments of the entire body of recorded information within a vast hierarchical information network. he estimates 52 journal of. library automation vol. 2/1 marc;:h, 1969 the present world corpus of knowledge could be stored in 1015 bits of computer memory. the rate of increase is 2·106 bits per second. part two explores the use of computers within the procognitive system. subjects touched upon include syntactical analysis of natural languages, quantitative aspects of the representation of information, information retrieval effectiveness, and question-answer systems. some time is spent with studies of current computer techniques. in general, part two is a trifle dated as it deals with specific techniques in a field where technological obsolescence is precipitous. . mr. licklider's writing is both intellectually stimulating and delightful. in discussing the future computer console, " ... the concept of ·desk' may have changed from passive to active: a desk may be primarily a displayand-control station in a telecommunication-telecomputation system---,and its most vital part may be the cable (umbilical cord) that connects it, via a wall socket, into the procognitive utility net," a footnote goes on to say, "if a man wishes to get away from it all and think in peace and quiet, he will have merely to turn off the power. however, it may not be economically feasible for his employer to pay him full rate for the time he thus spends in unamplified cerebration." serious students of information or library science should consider this book required reading if for no other reason than the jolt it provides one's imagination1 gerry d. guthrie editorial board thoughts: ital 2.0 | boze 57 litablog.org/) i see that there are occasional posts, but there are rarely comments and little in the way of real discussion. it seems to be oriented toward announcements, so perhaps it’s not a good comparison with italica. some ala groups are using wordpress for their blogs, a few with user comments, but mostly without much apparent traffic (for example, the ll&m online blog, http://www .lama.ala.orgllandm). in general, blogs don’t seem to be a satisfactory platform for discussion. wikis aren’t particularly useful in this regard, either, so i think that rules out the lita wiki (http://wikis.ala.org/lita/index.php/ main_page). i’ve looked at ala connect (http://connect. ala.org/), which has a variety of web 2.0 features, so it might be a good home for italica. we could also use a mailing list, either one that already exists, such as lita-l, or a new one. the one advantage e-mail has is that it is delivered to the reader, so one doesn’t have to remember to visit a website. we already have rss feeds for the italica blog, so maybe that works well enough as a notification for those who subscribe to them. i’ve also wondered whether a discussion forum (aka message board) would be useful. i frequent a few software-related forums, and i find them conducive to discussion. they have a degree of flexibility lacking in other platforms. it’s easy for any participant to start up a new topic rather than limiting discussion only to topics posted by the owner, as is usually the case with blogs. frankly i’d like to encourage discussion on topics beyond only the articles published in ital. for example, we used to have columns devoted to book and software reviews. even though they were discontinued, those could still be interesting topics for discussion between ital readers. in writing this, my hope is to get feedback from you, the reader, about what ital and italica could be doing for you. how can we use ala connect in ways that would be useful? could we use other platforms to do things beyond simply discussing articles that appear in the print edition? what social web technologies do you use, and how could we apply them to ital? after you read this, i hope you’ll join us at italica for a discussion. let us know what you think. editor’s note: andy serves on the ital editorial board and as the ital website manager. he earns our gratitude every quarter with his timely and professional work to post the new issue online. t he title of this recurring column is “editorial board thoughts,” so as i sit here in the middle of february, what am i thinking about? as i trudge to work each day through the snow and ice, i think about what a nuisance it is to have a broken foot (i broke the fifth metatarsal of my left foot at the midwinter meeting in boston—not recommended) but most recently i’ve been thinking about ital. the march issue is due to be mailed in a couple of weeks, and i got the digital files a week or so ago. in a few days i’ll have to start separating the pdf into individual articles, and then i’ll start up my web editor to turn the rtf files for each article into nicely formatted html. all of this gets fed into ala’s content management system, where you can view it online by pointing your web browser to http://www.lita.org/ala/mgrps/divs/lita/ ital/italinformation.cfm. in case you didn’t realize it, the full text of each issue of ital is there, going back to early 2004. selected full-text articles are available from earlier issues going back to 2001. the site is in need of a face lift, but we expect to work on that in the near future. starting with the september 2008 issue of ital we launched italica, the ital blog at http://ital-ica .blogspot.com/, as a pilot. italica was conceived as a forum for readers, authors, and editors of ital to discuss each issue. for a year and a half we’ve been open for reader feedback, and our authors have been posting to the blog and responding to reader comments. what’s your opinion of italica? is it useful? what could we be doing to enhance its usefulness? in reality we haven’t had a great deal of communication via the blog. we are looking at moving italica from blogger to a platform more integrated with existing ala or lita services. is a blog format the best way to encourage discussion? when i look at the lita blog (http:// andy boze (boze.1@nd.edu) is head, desktop computing and network services, university of notre dame hesburgh

december 2013 5 immersive technologies—interactive 3d graphics, simulation, and gaming technologies—have much to offer higher education by collapsing geography and by providing a richer learning environment. over the past forty years, through digitization and internet services, librarians have brought technology to bear on making it easier to find and use information, even to the point where people can find and use library resources without coming to the library. information space—the space between user and literature—has been collapsed through digital access. now there is potential to collapse the space between users themselves as they work together from different locations. in recent decades, learning has gone from a predominantly independent and competitive process for students to one that makes greater use of collaboration, cooperation, and group study. the library as a place for students and researchers to work individually with their literature has become a collaborative workspace where students work together on research projects and shared class assignments. this presents a challenge to libraries and learning institutions with limited space for students to meet, share ideas, do coursework together, work on joint projects, and practice presentations. for more than five years, advances in the development of virtual meeting space and workspace have enabled librarians to provide immersive, 3d virtual world services that give a sense of presence that is lacking in conference calls, text chat, and web conferencing.1 as a result, not only is the individual’s physical distance from library materials eliminated, but also the distance is eliminated between individuals who work with each other using library materials. immersive technologies offer the promise of 3d virtual world libraries where students and their teachers can work together in virtual space with library materials and tools—search engines, online catalogs, media, text, etc. students would sit at their computer wherever they are and work together with classmates in a shared environment, using library materials as well as productivity tools—word processor, spreadsheet, web, or blog development software. this would be a boon for real-world institutions lacking sufficient physical space, but also for distance education and international education. for example, students might study abroad but take a class at their home institution, take classes with classmates at foreign institutions, learn jerome yavarkovsky (jeromey@bc.edu) is emeritus university librarian, boston college, and founding co-chair of the libraries and museums technology working group under the immersive education initiative of the media grid. editorial board thoughts | yavarkovsky 6 languages and experience foreign cultures more directly, or take classes in locales not accessible to professors. and now, with the advent of massive open online courses, the opportunity lies within the immersive library to serve large numbers of students who have limited or no library facilities. these students would be able to use library resources as well as to communicate and work with classmates, teaching assistants, tutors, and others whose support would be augmented through their virtual presence rather than via email or text chat. as current research material is born digital, and legacy material is digitized at accelerating rates and is delivered digitally, they are perfect for use in immersive environments. however, immersive library resources are not limited to traditional materials. they include virtual world learning objects and environments, and virtual representations of books—walk-in books or educational simulations—that are interactive experiences with literature.2 further, in virtual space, physical research objects can be part of the study environment and be brought into an active relationship with the information resources that pertain to them. for example, if you were studying 3d models of mayan pottery in a virtual library workspace, you would have access to historical accounts, conference papers, current periodical articles, photographic archives, dissertations and other material pertinent to your studies. through this, not only would distance be eliminated between individuals and library materials, but also physical research objects from pottery to architecture, from monuments to molecular models could be represented in virtual space and related to the information that pertains to them.3 so whether the collaborators are students, teachers, librarians, researchers, we can see a time, even now, when they will no longer be bound by physical workspace. in addition to the immersive library as repository and collaborative study space, the immersive library can be expected to offer enhanced services to users. for example, immersive information literacy programs, immersive research and course consultations, virtual interlibrary document management, and document delivery are just a few possibilities. the immersive workspace is a logical setting for instructing students in digital literacy, the evaluation of resources, and the use of information tools. the goal here would be to bring into the immersive environment the rich body of course designs and curriculum materials pertaining to the educated use of information. we know that among the most significant lifelong benefits of higher education are information skills—finding, evaluating, and using information for work or for personal enrichment. research and course consultations are further academic services that would be valuable applications in the immersive library. librarians, library assistants, and docents have all helped individuals in second life and opensim libraries by providing advice, information, and guidance. these services have further potential in 3d virtual environments through enhancement with photographs, documents and virtual structures. add to these the tools and resources of the library collaborative workspace, and the potential for student and faculty consultation and advisory information technology and libraries | december 2013 7 services is even greater. imagine the phd candidate or student with a writing assignment in the library space with the librarian and all the tools needed for help with dissertation research. as immersive libraries realize their potential and grow in number and scale, the challenge of managing them will grow as well. the tools of 3d virtual workspaces hold promise here also to facilitate the work of the library and improve librarian productivity. librarians work across geographic boundaries regionally and nationally in consortia and multitype systems for resource sharing, collaborative research and development projects, digitization initiatives, staff development programs, and any number of efforts to economize and improve performance. the very management of the library enterprise should benefit from 3d virtual reality tools brought to bear on the day-to-day work and communication of the library. for any who might want to learn more, the ala virtual communities and libraries member initiative group maintains an ala connect site (http://connect.ala.org/node/66325). communication on libraries in virtual environments is also available

harvesting by search engines such as google and yahoo!. if a library instead exposes its content through a local search interface, that content can then be found by users of metasearch engines such as a9 and vivísimo. the functionality provided by the local search engine will affect the functionality of the metasearch engine and the findability of the library’s content. this paper describes that situation and some emerging standards in the metasearch arena that choose different balance points between functionality and ease of implementation. editor's note: this article was submitted in honor of the fortieth anniversaries of lita and ital. ฀ the content provider’s dilemma consider the increasingly common situation in which a library wants to expose its digital content to its users. suppose it knows that its users prefer search engines that search the contents of many sites simultaneously, rather than site-specific engines such as the one on the library’s web site. in order to support the preferences of its users, this library must make its contents accessible to search engines of the first type. the easiest way to do this is for the library to convert its contents to html pages and let the harvesting search engines such as google and yahoo! collect those pages and provide searching on them. however, a serious problem with harvesting search engines is that they place limits on how much data they will collect from any one site. google and yahoo! will not harvest a 3-million-record book catalog, even if the library can figure out how to turn the catalog entries into individual web pages. an alternative to exposing library content to harvesting search engines as html pages is to provide a local search interface and let a metasearch engine combine the results of searching the library’s site with the results from searching many other sites simultaneously. users of metasearch engines get the same advantage that users of harvesting search engines get (i.e., the ability to search the contents of many sites simultaneously) plus those users get access to data that the harvesting search engines do not have. the issue for the library is determining how much functionality it must provide in its local search engine so that the metasearch engine can, in turn, provide acceptable functionality to its users. the amount of functionality that the library provides will determine which metasearch engines will be able to access the library’s content. metasearch engines, such as a9 and vivísimo, are search engines that take a user’s query, send it to other search engines, and integrate the responses.1 the level of integration usually depends on the metasearch engine’s ability to understand the responses it receives from the various search engines it has queried. if the response is html intended for display on a browser, then the metasearch engine developers have to write code to parse through the html looking for the content. in such a case, the perceived value of the content determines the level of effort that the metasearch engine developers put into the parsing task; low-value content will have a low priority for developer time and will either suffer from poor integration or be excluded. for metasearch engines to work, they need to know how to send a search to the local search engine and how to interpret the results. metasearch engines such as vivísimo and a9 have staffs of programmers who write code to translate the queries they get from users into queries that the local search engines can accept. metasearch engines also have to develop code to convert all the responses returned by the local search engines into some common format so that those results can be combined and displayed to the user. this is tedious work that is prone to breaking when a local search engine changes how it searches or how it returns its response. the job of the metasearch engine is made much simpler if the local search engine supports a standard search interface such as sru (search and retrieve url) or opensearch. ฀ what does a metasearch engine need in order to use a local search engine? the search process consists of two basic steps. first, the search is performed. second, records are retrieved. to do a search, the metasearch engine needs to know: 1. the location of the local search engine 2. the form of the queries that the local search engine expects 3. how to send the query to the local search engine to retrieve records, the metasearch engine needs to know: 4. how to find the records in the response 5. how to parse the records opensearch and sru: a continuum of searching ralph levan ralph levan (levan@oclc.org) is a research scientist at oclc online computer library center in dublin, ohio. 152 information technology and libraries | september 2006 ฀ four protocols this paper will discuss four search protocols: opensearch, opensearch 1.1, sru, and the metasearch xml gateway (mxg).2 opensearch was initially developed for the a9 metasearch engine. it provides a mechanism for content providers to notify a9 of their content. it also allows rss (really simple syndication) browsers to display the results of a search.3 opensearch 1.1 has just been released. it extends the original specification based on input from a number of organizations, microsoft being prominent among them. sru was developed by the z39.50 community.4 recognizing that their standard (now eighteen years old) needed updating, they simplified it and created a new web service based on an xml encoding carried over http. the mxg protocol is the product of the niso metasearch initiative, a committee of metasearch engine developers, content providers, and users.5 mxg uses sru as a starting place, but eases the requirement for support of a standard query grammar. ฀ functionality versus ease of implementation a library rarely has software developers. the library’s area of expertise is, first of all, the management of content and, secondarily, content creation. librarians use tools developed by other organizations to provide access to their content. these tools include the library’s opac, the software provided to search any licensed content, and the software necessary to build, maintain, and access local digital repositories. for a library, ease of adoption of a new search protocol is essential. if support for the search protocol is built into the library’s tools, then the library will use it. if a small piece of code can be written to convert the library’s existing tools to support the new protocol, the library may do that. similarly, the developers of the library’s tools will want to expend the minimum effort to support a new search protocol. the tool developer’s choice of search protocol to support will depend on the tension between the functionality needed and the level of effort that must be expended to provide and maintain it. if low functionality is acceptable, then a small development effort may be acceptable. high functionality will require a greater level of effort. the developers of the search protocols examined here recognize this tension and are modifying their protocols to make them easier to implement. the new opensearch 1.1 will make it easier for some local search-engine providers to implement by easing some of the functionality requirements of version 1.0. similarly, the niso metasearch committee has defined mxg, a variant of sru that eases some of the requirements of sru.6 ฀ search protocol basics once again, the five basic pieces of information that a metasearch engine needs in order to communicate effectively with a local search engine are: (1) local search engine location, (2) the query-grammar expected, (3) the request encoding, (4) the response encoding, and (5) the record encoding. the four protocols provide these pieces of information to one degree or another (see table 1). the four protocols expose a site’s searching functionality and return responses in a standard format. all of these protocols have some common properties. they expect that the content provider will have a description record that describes the search service. all of these services send searches via http as simple urls, and the responses are sent back as structured xml. to ease implementation, opensearch 1.1 allows the content provider to return html instead of xml. all four protocols use a description record to describe the local search engine. the opensearch protocols define what a description record looks like, but not how it is retrieved. the location of the description record is discovered by some means outside the protocol (a priori knowledge). the description record specifies the location of the local search engine. the sru protocols define what a description record looks like and specifies that it can be obtained from the local search engine. the location of the local search engine is provided by a means outside the protocol (a priori knowledge again). each protocol defines how to formulate the search url. opensearch does this by having the local search-engine provider supply a template of the url in the description record. sru does this by defining the url. opensearch and mxg do not define how to formulate the query. the metasearch engine can either pass the user’s query along to the local search engine unchanged or reformulate the query based on information about the local search engine’s query language that it has gotten by outside means (more a priori knowledge). in the first case, the metasearch engine has to hope that some magic will happen and the local search engine will do something useful with the query. in the latter case, the metasearch engine’s staff has to develop a query translator. sru specifies a standard query grammar: cql (common query language).7 this means that the metasearch engine only has to write one translator for all the sru local search engines in the world. but it also means that all the sru local search engines have to support the cql query grammar. since there are no local search engines that support cql as their native query grammar, the content provider is left with the task of translating cql queries into their native query grammar. the query translation task has moved from the metasearch engine to the content provider. opensearch and sru | levan 153 opensearch 1.0, mxg, and sru define the structure of the query response. in the case of opensearch, the response is returned as an rss message, with a couple of extra elements added. mxg and sru define an xml schema for their responses. opensearch 1.1 allows the local search engine to return the response as unstructured html. this moves the requirement of creating a standard response from the content provider and leaves the metasearch engine with the much tougher task of finding the content embedded in html. if the metasearch engine doesn’t write code to parse the response, then all it can do is display the response. it will not be able to combine the response from the local search engine with the responses from other engines. sru and mxg require that records be returned in xml and that the local search engine must specify the schema for those records in the response. this leaves the content provider with the task of formatting the records according to the schema of their choice, a task that the content provider is probably best able to do. in turn, the metasearch engine can convert the returned records into some common format so that the records from multiple local search engines can be combined into a single response. because the records are encoded in xml, it is assumed that standard xml formatting tools can be used for the conversion. opensearch does not define how records should be structured. the opensearch response has a place for the title of the record and a url that points to the record. the structure of the record is undefined. this leaves the metasearch engine with the task of parsing the record that is returned. again, the effort moves from the content provider to the metasearch engine. if the metasearch engine does not or cannot parse the records, then it can at least display the records in some context, but it cannot combine them with the records from another local search engine. ฀ conclusion these protocols sit on a spectrum of complexity, trading the content provider’s complexity for that of the search engine. however, with lessened complexity for the metasearch engine comes increased functionality for the user. metasearch engines have to choose what content providers they will search. those that provide a high level of functionality can be easily combined with their existing local search engines. content providers with a lower level of functionality will either need additional development by the metasearch engine or will not be searched. not all metasearch engines require the same level of functionality, nor will they be prepared to accept content with a low level of functionality. content providers, such as digital libraries and institutional repositories, will have to choose the functionality they need to support to reach the metasearch engines they desire. references and notes 1. joe barker, “meta-search engines,” in finding information

congress. 119 this paper is a statement of the library of congress' 1'ecommendation that a marc advisory committee be appointed within the present structure of the rtsd jisad jrasd committee on representation in machine-readable form of bibliographic information (marbi) and describes the library's proposed relation to such a committee. the proposals and recommendations suggested were adopted by the marbi committee dming its deliberations at ala midwinter, janua1'y 1974, and a1'e now in effect. introduction during ala midwinter, january 1973, the library of congress (lc) suggested to the rtsd/isad/rasd committee on representation in machine-readable form of bibliographic information that a marc advisory committee be formed to work with the marc development office regarding changes made to the various marc formats. the primary interest of the committee would be the serial and monograph formats, though the committee should have interest in and responsibility for reviewing changes in any of the marc formats to insure that the integrity and compatibility of marc content designators are preserved. the marbi committee decided that it would be the marc advisory committee and asked that a paper be prepared proposing how such a committee would operate in relationship to the marc development office. prior to a discussion of marc changes, it appears appropriate to make certain basic statements regarding marc changes and the difficulties experienced by the marc development office in evaluating the significance of a change for the marc subscriber. it would be naive to assume, in a dynamic situation, that even in the best of all worlds a marc subscriber would never have to do any reprogramming. changes in procedures, changes in cataloging, experience in providing the knowledge for more efficient ways to process information, additional requirements from users, etc., have always been factors creating the 120 ] ournal of library automation vol. 7/2 june 197 4 need to both modify andjor expand an automated system. programming installations always require personnel to maintain ongoing systems. situations creating changes locally must exist and, likewise, they also exist at lc. staff of the marc development office give serious consideration to every proposed marc change and its impact on the marc subscribers. however, it must be realized that it is not possible to evaluate fully the impact of each change because the significance of a change is directly dependent on the use made of the elements of the record and the programming techniques used by each subscriber. marc staff cannot possibly know the details of use and programming techniques and capabilities at every user installation. each marc subscriber evaluates a change in light of his operational requirements. since the uses made of the data are varied among users, there is rarely a consensus as to the pros and cons of a change. marc staff are aware of the expenses imposed by changes to software and have made an attempt to solicit preferences in some cases for one technique over another from marc subscribers when changes were required. in the case of the isbd implementation, ten replies were received from questions submitted to the then sixty-two marc users. the remainder of this paper describes what is included in the term "change," the various stimuli that initiate changes, and recommendations of how lc and the marc advisory committee should interact in regard to changes. the appendix summarizes in chart form the addenda to books: a marc fo1·mat since the initiation of the marc service. an examination of the chart will reveal that the number and the types of changes have not been too significant. marc changes the term "change" is used throughout this paper in the broad sense, i.e., the term includes additions, modifications, and deletions of content data (in both fixed and variable fields) and content designators (tags, indicators, and subfield codes) made to the format as well as additions, modifications, and deletions made to the tape labels. the concern is with changes made to all records where applicable or groups of records but not with the correction or updating of individual records as part of the marc distribution service. changes as described above fall into several broad types: 1. addition of new fields, indicators, or subfield codes to the format. 2. implementation of aheady defined but unused tags, indicators, subfield codes, or fixed fields. 3. modification of content data of fields (fixed and variable). 4. changes in style of content in records, e.g., punctuation. 5. cessation in use of existing fields, indicators, and subfield codes. library of congress view/ avram 121 the following paragraphs are divided into two sections. section "a" describes the stimulus for a change and the rationale for making it. section "b" describes the lc position regarding the change and, where applicable, a recommendation to the marc advisory committee. changes made to marc records may be divided into the following categories: category 1: changes resulting from a change in cataloging rules or systems. a. cataloging rules or systems fall into two distinct types: those made in consultation with ala (resources & technical services division/cataloging & classification section/descriptive cataloging committee), and those made by the subject cataloging division to the subject cataloging system without consultation with ala. lc follows aacr. since the marc record is the record used for lc bibliographical control as well as the source record for the lc printed card and lc book catalogs (for those items presently within the scope of marc), cataloging changes (descriptive and subject) are necessarily reflected in marc. if the cataloging change is such that the retrospective records can reasonably be modified by automated techniques, these records are modified to reflect the change. prior to marc, this updating could not be provided to subscribers to lc bibliographic products and is one of the advantages of a machine-readable service. it has the effect of maintaining a consistent data base for all marc users. b. changes made in cataloging rules or systems will be made by the appropriate agencies. once changes in cataloging rules have been made by the ala (rtsdjccsjdcc) committee, lc will consult with the marc advisory committee with respect to their implementation in those cases affecting the marc format.'~* wherever possible, depending upon resources available, the number of records affected, and the type of change, the retrospective flies will be updated and made available in one of two ways: if the number of records is small (to be decided by lc), the records will be distributed as corrections through the normal channels of the marc distribution service. if the number of records is large, the records will be sold by the lc card division. category 2: changes made to satisfy a requirement of the library of congress. a. since lc uses the marc records for its own purposes, situations do arise in which lc has a requirement for a change. in most cases, lc feels that the change would also be beneficial to the users. under these circumstances lc has carefully evaluated the im""format change is used in this context to mean a change affecting the tags, indicators, subfield codes, addition or deletion of fixed fields, or change to the leader. 122 i oumal of libmry automation vol. 7/2 june 197 4 plication of the change to the marc subscribers and, in some cases, solicited their preferences and advice. b. if lc has a requirement to make a change to marc, the proposed change and the reason for the change will be referred to the marc advisory committee. the marc advisory committee will solicit opinions from marc users as to whether or not to include the change in the marc distribution service, and lc will abide by the committee's recommendation. if this decision is not to include the change, lc will implement the change only in its own data base.t category 3: changes made to satisfy subscribers' requests. a. subscribers sometimes request that a change be made to a marc record. where possible, within the limitation of lc resources, these requests are complied with. lc, when considering such a request, has sought the opinion of the marc subscribers, and if sufficient numbers of users were interested in the change, the change was implemented. b. changes requested by subscribers will be evaluated by lc, and if considered possible to implement, the proposed change will be submitted by lc to the marc advisory committee to solicit opinions from marc users. if the committee recommends, lc will implement the change. catego1·y 4: changes made to support international standardization. a. lc plays a significant role in international activities in the area of machine-readable cataloging records. much of the future expansion of marc depends upon standards in formats, data content, and cataloging. in all these activities, lc firmly supports aacr and current marc formats. occasionally, in order to arrive at complete agreement with agencies in other countries, it becomes necessary for all to compromise. however, in all cases lc does not agree to changes in cataloging rules until the recommendation has been approved by the appropriate ala committee. b. changes resulting from international meetings will fall principally into two areas: 1. cataloging-if the change required is the result of a change in cataloging rules and the ala (rtsdjccsjdcc) has approved the aacr modifications, the marc change falls into category 1. 2. all other changes affecting the format-since lc is the agency in the u.s. that will exchange machine-readable bibliographic records with other national agencies, lc will consider these t an exception to this statement will be those changes to lc practice which must be reflected on cards and in the marc record and which cannot exist in optional form. an example of the above would be abolition of the check digit in the lc card number. libmry of congress viewj avram 123 changes an internal lc requirement; therefore, they can be considered under the proposal described in category 2. lc will submit the proposed changes to the marc advisory committee. category 5: changes made to expand the marc program to include additional services. a. if the marc service were static, changes to expand the service would not be possible. an example of an additional service is the cataloging in publication data available on marc tapes. since these cataloging data are available four to six months prior to the publication of the item, it was determined to be of value to marc subscribers and'changes were made to the marc record to make these data available in machine-readable form. b. if a new service is under consideration at lc that will cause a change to marc records, e.g., cataloging in publication, lc will submit the proposal to the marc advisory committee for their action as described in category 2. other lc recommendations for the marc advisory committee 1. time fmme fo1' changes. in order to prevent consultation on changes from taking an inordinate length of time, lc proposes that the marc advisory committee be given two months to solicit comments from marc users, to arrive at a consensus, and to respond to proposed changes. if there is no response during that time, lc will implement the proposed change. lc will notify the marc subscribers two months prior to including the change in the marc distribution service. 2. consultation with the marc advisory committee. the marc development office will submit the recommendation for change and any other information required to evaluate the change to the marc advisory committee. the marc advisory committee will be responsible for submitting the proposal to the marc users and notifying the marc development office of the committee's recommendation. 3. test tapes. the marc advisory committee, on consultation with the marc development office, will consider the requirement for a test tape to reflect the change made to the marc record (the requirement for a test tape is dependent on the type of change made). appendix a addenda to books: a marc format stimul~ for change date change 1.

which, it is hoped, will be implemented soon. multimedia catalog: com and online kenneth j. bierman: tucson public library, tucson, arizona. like many public libraries, the tucson public library (tpl) is closing its card catalog and implementing a vendorsupplied microform catalog. unlike most of these other libraries, however, the tpl microform catalog will not include', location or holding information. the indication of where copies of a particular title are actually available (i.e., which of the fifteen possible branch locations) will be available only by accessing a video display terminal connected to the online circulation and inventory control system. conceptually, the tpl catalog will be in two parts with each part intended to serve different functions.' the microform catalog (copies available in both film and fiche format) will fulfill the bibliographic function of the catalog. this catalog will contain bibliographic description and provide the traditional access points of author, title, and subject. the online catalog (online terminals are in place at all reference desks and a few public access terminals will also be available) will fulfill the finding or locating function of the catalog. this catalog will contain very brief bibliographic description and will only be searchable by author, title, author/title, and call number, and will contain the current status of every copy of every title in the library system (i.e., on shelf, checked out, at bindery, reported missing, etc.). why did the tucson public library make this decision? there are two major reasons: l. accuracy . the location information, if provided in the microform catalog, would always be inaccurate and out of date. assuming that the locations listed in the latest edition of the microform catalog were completely accurate when the catalog was first issued (an unrealistic assumption to begin with as anyone who has ever worked with location information at a public library with many branches well knows!), the location information would become increasingly less accurate with each day because of the large number of withdrawals, transfers, and added copy transactions that occur (more than 100,000 a year) . in addition, at any given time, one-quarter to one-third of the materials in busy branches are not on the shelf because they are either checked out or waiting to be reshelved . thus, the microform catalog would indicate that these materials were available at specific branches when a significant percentage would in fact not be available at any given time. in short, even in the best of circumstances, easily half of the location information would be incorrect in telling a user where a copy of a title was actually available at that moment. 2. cost , a study done at the tucson public library indicated that close to half of the staff time of the cataloging department was spent dealing with location and holding information. this time includes handling transfers, withdrawals, and added copies. all of this record keeping is already being done as a part of the online circulation and inventory control system (the tucson public library has no card shelflist containing copy and location information but rather relies completely on the online file for this type of information). to "duplicate" the information in the microform catalog would cost an estimated $40,000 to $60,000 a year and the information in the microform catalog would never be accurate or up to date for the reasons outlined above . figure 1 is a brief summary of how the bibliographic system will work. would the system in figure 1 be improved if holdings were included in the microform catalog? on the surface, the obvious answer is yes-more information is communications 111 known-item search (37 percent of tpl catalog use according to catalog use survey conducted at the tpl in 1971) user searches microform catalog by author and/or title. if user does not find desired bibliographic entry, user either leaves unsatisfied or goes to desk (or public access terminal) for help. if user finds the desired bibliographic entry, he/she writes down call number (or author for fiction) and proceeds to shelf. if user finds book on shelf he/she checks it out. if user does not find book on shelf, user either leaves unsatisfied or goes to desk (or public access terminal) to obtain holdings information or ask for help (put on reserve, borrow from another library, possible purchase of additional copies, etc.). subject search (63 percent of tpl catalog use by public according to catalog use survey conducted at the tpl in 1971) user searches microform catalog. user writes down call number(s) and proceeds to shelf. if user finds appropriate material(s), he/she checks it out. if user does not find appropriate material he/she leaves unsatisfied or goes to desk for help (reference interview, etc.) . fig. 1. summary of how system will work. always better. but, if we examine the situation in depth, perhaps not. let us look at some hypothetical situations. if the user is doing a search and does not find the desired entry/entries in the microform catalog, it makes no difference whether holdings are included in the catalog. the user will still either leave unsatisfied or go to the desk for help. if the user is doing a known-item search and finds the desired item and notes, and the agency he/she is at is listed as a holding agency, he/she will proceed to the shelf. if the desired material is found, fine . if not (because the material is checked out, reported missing, or withdrawn), he/she will either leave unsatisfied or go to the desk (or public access terminal) for help. if the user is doing a known-item search and finds the desired item in the microform catalog but notes that the agency is not listed as a holding agency, what are his/her choices? the user can go away unsatisfied without checking the shelves (although there may be a copy on the shelf because a copy may have been added to that agency since the microform catalog was last recumulated) or he/she can go to the desk (or public access terminal) to obtain help; here he/she will have access to the "real" holdings information--on the online system. the user could notice from the holdings in the microform catalog that another branch has the item and drive to the other branch. however, when the user gets there he/she may discover that the item is not available-information that could have been found in the online system at the original branch if he/she had gone to the desk (or public access terminal). · the purpose of the above exercise is to demonstrate that in all cases the user is still going to require access to the online catalog in order to determine holdings more accurately. with time, this access will become increasingly self-service through public access terminals. from the user's point of view, providing inaccurate holdings in the microform catalog does very little good and can actually do harm by leaving the impression that, if a library is listed as a holding library, that library will have the item (a false conclusion because of checkouts, reported missings, and withdrawals) or leaving the impression that if a library is not listed as a holding library, that library will not have the item (a false conclusion because a copy could have been added recently but that fact is not yet reflected in the microform catalog) . if the user is doing a subject search, holdings are of less value in the catalog 112 journal of library automation vol. 14/2 june 1981 anyway because he is primarily getting suggested classification numbers in order to browse. the tucson public library could not have made the above decisions if it did not have a complete online file of all its holdings (including even reference materials that never circulate). but since this data did exist (after a five-year bar-coding effort) and since more than forty online terminals were already in place throughout the library system to access the online file, the decision not to include locations or holdings in the microform catalog seemed reasonable . in the longer-range future (1990?), it is very likely that the entire catalog will be available online . in the meantime, the tucson public library did not want to divide its resources maintaining two location records, but rather wanted to concentrate resources in maintaining one accurate record of locations available as widely as possible throughout the library system (by installing more online terminals for staff and public use). was this decision a sound one? we don't know. the microform catalog has not yet been introduced for public use. by the end of this year we should have some preliminary answers to this question. references 1. robin w. macdonald and j. mcree elrod, "an approach to developing computer catalogs," college & research libraries 34:202-8 (may 1973). a structure code for machine readable library catalog record formats herbert h. hoffman: santa ana college, santa ana, california. libraries house many types of publications in many media, mostly print on paper, but also pictures on paper, print and pictures on film, recorded sound on plastic discs, and others. these publications are of interest to people because they contain recorded information. more precisely said, because they contain units of intellectual, artistic, or scholarly creation that collectively can be called "works." one could say simply that library materials consist of documents that are stored and cataloged because they contain works. the structure of publications into documents (or "books") and works, the clear distinction between the concept of the information container as opposed to the contents, deserves more attention than it has received so far from bibliographers and librarians. the importance of the distinction between books and works has been hinted at by several theoreticians, notably lubetzky . however, the idea was never fully developed. the cataloging implications of the structural diversity among documents were left unexplored. as a consequence, librarians have never disentangled the two terms book and work . from the paris principles and the marc formats to the new second edition of the anglo-american cataloguing rules, the terms book and work are used loosely and interchangeably, now meaning a book, now a work proper, now part of a work, now a group of books. such ambiguity can be tolerated as long as each person involved knows at each step which definition is appropriate when the term comes up. but as libraries ease into the age of electronic utilities and computerized catalogs based on records read by machine rather than interpreted by humans, a considerably greater measure of precision will have to be introduced into library work. as one step toward that goal an examination of the structure of publications will be in order. the items that are housed in libraries, regardless of medium, are of two types. they are either single documents, or they are groups of two or more documents. items that contain two or more documents are either finite items (all published at once, or with a first and a last volume identified) or they are infinite items (periodicals, intended to be continued indefinitely at intervals). schematically, these three types of bibliographic items in libraries can be represented as shown in figure l. it should be noted that all publications, all documents, all bibliographic items in lilib-mocs-kmc364-20131012113553 230 i ournal of library automation vol. 14/3 septem her 1981 for member libraries and will demonstrate their system in mid-1981. oclc data has been successfully transferred to many local circulation systems. rlgirlin rlin does not anticipate offering local circulation services for member libraries. rlin data has been successfully transferred to several local circulation systems. wln wln does not anticipate offering local circulation systems on their computer for member libraries. wln data has been successfully transferred to local circulation systems and an agreement has been reached with dataphase, a computerized circulation system vendor, to discount purchase of their system by wln member libraries. public online catalogs again, none of the bibliographic utilities under consideration currently support public online catalogs of an individual library's collection. a public online catalog requires further programming in order to make it easy for the public to locate materials of interest without extensive training; the bibliographic utility's searching procedures are too esoteric to be used by the general public. as in circulation, issues of data transferability and full retrospective conversion of the uo library's catalog are paramount. oclc oclc does not currently encourage public access to their database and does not support use of local online catalogs on their computer due to the tremendous demand for computer resources exerted by 2400 member libraries. oclc and rlg /rlin are participating in a study of user requirements for a public online catalog. oclc data has been successfully transferred to several local online catalogs, including eugene public library's circulation and online catalog system, ulisys. rlg!rlin rlin anticipates being able to offer public access to their database. they are participating in a study with oclc of user requirements for such a system, but no date has been announced for the development of this capability in rlin. rlin data has been successfully transferred to a local public online catalog at northwestern university. wln wln does not believe that a local online patron accessed catalog should be provided through the wln computer, even though they anticipate having such a capability within one year. instead, they encourage libraries to develop local systems for public access to the online computerized catalog and to obtain data from the wln cataloging system. the university of illinois is adapting the wln computer search and database management software to provide a local online catalog and computerassisted instruction in its use for the public. checklist for cassette recorders connected to crts prepared by lawrence a. woods: purdue university libraries, west lafayette, indiana, for the technical standards for library automation committee, information science and automation section, library and information technology association. introduction a data cassette recorder connected to a printer port is an effective, low-cost method of collecting data in machine-readable form from display terminals such as the oclc 100/105. it is important that a data recorder be used rather than an audio recorder although the cassette itself can be a goodquality audio tape. it is also important to note that the data recorded on the tape are not the same as the data originally transmitted to the display terminal, but are simply a line-by-line image of what appears on the screen. a typical installation will have a minimum of two devices: one attached to the display terminal to collect data, and one attached to a printer or an input device to another computer for playback of the data. there are more than 150 various data recording devices on the market. this checklist is prescriptive in nature, outlining and describing those features that are necessary or desirable for a typical application. in addition to features, environmental considerations are briefly mentioned along with information for the purchase, lease, or rental of data equipment. features in general, featu.res must be compatible between all devices used for recording and playback in a given application. some features that are desirable for certain applications are unnecessary or inappropriate for others. 1. recording media the phillips cassette is most widely used and may be interchanged between the recorders of different manufacturers that utilize it. the cartridge (either 3m or a vendor proprietary cartridge) is gaining popularity because of its greater storage and transfer rates, but as yet is not widely used. 2. code most print ports on display terminals use ascii (american standard code for information exchange) data code. the recorder selected should use the same. 3. interfaces the cassette recorder has an "in" plug to accept data. this must be compatible with the print port on the terminal-usually rs232c. the "out" plug on the recorder sends the recorded data to a printer or to a computer. this interface should also be rs232c. 4. recording characteristics a. the number of tracks can vary from one to four. this is one of the factors that determine the amount of data that can be recorded on a single cassette. four tracks are recommended. b. density also affects the amount of data that can be recorded. usual densities are 800 or 1,600 bits per inch (bpi). c. recording mode. thereareseveral reports and working papers 231 modes available. phase encoded (pe) is the best mode for data applications. non-return to zero (nrz) is a popular mode, but has poor error recovery. ibm has a version called nrzi, which improves on nrz but still is less reliable than phase encoded. other commonly found modes are complementary nrz and ratio recording. d. recording format. there is a variety of recording formats. to be assured compatibility with the terminal and playback device the format should be either ansi (american national standards institute) or ecma (european computer manufacturers association) compatible. 5. transmission a. duplex. the recorder should have both full and half duplex available. b. data transfer rate (baud rate). baud rate is usually switchselectable from 110 to 9600. the recorder must be set at the same speed as the printer port on the terminal. the oclc 100 and 105 terminals have a printer port baud rate selection switch that may be setat100,150,300,600,1200,and a meaningless 1800 baud. select a recorder that has the fastest compatible setting: 1200 baud is best. data must be played back at a rate compatible with the receiving device. 6. tape transport characteristics a. read/write speed is usually a function of the baud rate. b. non recording speeds. this feature is important for convenience. fast forward and rewind should be available. one hundred twenty inches per second will rewind a cassette in about thirty seconds. c. drive mechanism. four options are available: capstan, pinch roller, servomechanism, or reel-toreel. pinch roller is the most precise but reduces the life of the tape. 7. packaging 232 journal of library automation vol. 14/3 september 1981 this feature can affect the price of the final configuration. if any item is listed as "separate," increase the total price accordingly. components that can be either internal or separate are: controller, interface, or power supply. 8. remote operation some devices use ascii control codes to trigger controls automatically. this is a useful feature, but the device must have a transparent mode switch, otherwise codes embedded in the data being recorded or sent may trigger undesired operations such as rewind. 9. operating characteristics a. rewind, fast forward, initialize, send and receive are all necessary operations and should be switchcontrolled. b. edit, auto program search, string search, skip, etc., are useful for word-processing operations but are of little use in simple data collection and transmission. c. read backward is desirable for sort operations. d. character mode, line mode, and string mode are useful for printing operations but of little use in data transmission. e. online/offline should be switchselectable. f. simultaneous read/write is useful for editing operations. g. direct block accessing is useful if there is a need to search for recorded data but is not used in sequential processing. h. auto reverse is a useful feature for recording or transmitting more data than can be recorded on one side of a cassette. environmental requirements i. humidity range humidity range should be 20 percent to 80 percent without condensation. lower humidity will cause excessive static electricity. 2. temperature temperature range should be between ten degrees and forty degrees centigrade. 3. power requirements most recorders require a standard 115-volt alternating current at 47 to 63hz. and draw about 60 watts. the circuit should be free from interference such as that caused by florescent lights. a transformer may be required in the outlet to guarantee even power. 4. space requirements the recorder usually can be stored on a desk top. it is important that the indicator lights be visible to the terminal operator to monitor its operation. purchase i. maintenance and availability ask how many drives the manufacturer has installed to date. this may vary from a few hundred to one hundred thousand or more. establish a maintenance contract with the company or a local service bureau. it may be necessary to acquire a spare recorder to use as backup. 2. price determine ahead of time what features you are actually going to use. bells and whistles all cost money. a simple reliable recorder can be purchased for around $700. multiple drive units and other features can run as high as $3,600. presidents ฀ ฀ ฀ ฀ ฀ ฀ ฀฀ ฀฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀

฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ president's column 114 information technology and libraries | september 2006 b eing president of a dynamic organization like lita is truly a humbling experience. every day i am awestruck by the dedication, energy, creativity, and excitement exhibited by lita’s members. i see it in everything that lita does, from its stellar publications and communications—including this journal, ital—to its programming and contribution to standards and system development. none of this would be possible without the hard work of all the dedicated members who volunteer their time not only to advancing their own professional development, but also to advancing the profession. thank you all. for forty years now, lita members have been dedicated to the association’s work, and we have been celebrating our fortieth anniversary throughout 2006. the celebration continues as we prepare to convene in nashville for the ninth lita national forum, october 26– 29, 2006. lita has had a long tradition of providing quality conferences. the first, held in 1970, was the conference on interlibrary communications and information networks, more familiarly known as the “airlie conference,” which had published proceedings. the second was a cooperative effort held in 1971 with the library education division and the american society for information science (asis), entitled “directions in education for information science: a symposium for educators.” in later years, lita held three national conferences: baltimore (1983), boston (1988), and denver (1992). in 1996, lita and the library administration and management association (lama) held a joint conference in pittsburgh. while the national conferences were very successful, the idea of a more informal, intimate event to be held annually took form, and in 1998 lita held its first annual national forum. next year we will continue the tradition of successful conference programming as we celebrate the tenth anniversary of the lita national forum in denver. this year’s theme is “netville in nashville: web services as library services.” we have an exciting lineup of keynote and concurrent-session speakers as well as several poster-session presenters who will stimulate lively discussions in all of the wonderful, informal networking opportunities this small conference offers. the sponsor showcase allows plenty of time for attendees to talk to our valued sponsors and learn more about their products. the two preconference programs offer in-depth experiences: “opensource installfest” and “developing best project management practices for it projects.” lita bloggers will be out in force producing summaries and reactions to it all. one of lita’s strongest membership benefits is the personal networking opportunities it provides. by providing an informal and enjoyable atmosphere, the national forum is one of the best places to network with others dealing with the same issues as you. i hope to see you there. besides the national forum (just one of lita’s many educational programs), one of the things i like most about lita is its flexibility to quickly accommodate programming to cover the latest issues and trends. lita’s programming at ala annual conferences attracts attendees from all divisions for this reason. every year, the highly successful top technology trends attracts more and more people who come to listen to the experts speak on the latest trends. the lita interest groups, like the technologies they focus on, also exhibit great flexibility because they can come and go—it’s easy to locate a few other members to create a new group where interested parties can come together for focused discussions or formal presentations. since its inception, lita has had traveling educational programs to provide programming opportunities for people who cannot attend the ala conferences. these in-depth programs, now called the regional institutes, focus on a topic and are offered as long as that issue is relevant. look for new electronic delivery of lita programs in the future. of course, lita’s publications provide a very lasting educational component. lita launched journal of library automation (jola), the predecessor of ital, in 1968, one year after the formation of the new division of ala. jola and, later, ital have consistently been a place for library information technologists to publish in a peer-reviewed scholarly journal. these well-respected publications have had a wonderful group of editors and editorial boards over the years. we are pleased that ital is now available online for members from the moment of publication. i want to thank all the people who work so hard to produce this publication on a quarterly basis. i also want to thank all the authors who submit their research for publication here and make a lasting contribution to the profession. all of these programs are just a sampling of what lita provides its members. is it any wonder i am awed by it all? i hope you are as well. i also hope that, in my year as your president, you will communicate with me in an open dialogue on the lita blog, via e-mail, or in person at conferences regarding how lita can better meet your needs as a member. we have been focusing a great deal on our educational goal because that is what we have heard you want out of lita. i encourage you to let me and the rest of the lita board know how we can best deliver a quality set of educational programs. president’s column bonnie postlethwaite bonnie postlethwaite (postlethwaiteb@umkc.edu)

british national bibliography, london, england 181 the cooperative development of the library of congress marc ii profect and the british national bibliography marc ii project is described and presented as the forerunner of an international marc network. emphasis is placed on the necessity for a standard marc record for international exchange and for acceptance of international standards of cataloging. this paper is an examination of two major operational automation projects. these projects, the library of congress marc ii project and the british national bibliography (bnb) marc ii project, are the result of sustained and successful anglo-american cooperation over a period of three years during which there has been continuous evaluation and change. in 1969, for a brief period, the systems developed have been stabilised, partly to give time for library systems to examine ways and means of exploiting a new type of centralised service, and partly to give the library of congress and the british national bibliography the opportunity to look outwards at other systems being developed in other countries. there has, of course, already been extensive contact and exchange of views between the agencies involved in the planning and developing of automated bibliographic systems and the possibilities of cooperation and exchange have been informally discussed at many levels. the time has now come for the national libraries and cataloguing agencies concerned to look at what has been achieved and to lay the foundation for effective cooperation in the future. the history of the anglo-american marc project began at the library 182 journal of library automation vol. 2/ 4 december, 1969 of congress with an experiment in a new way of distributing catalogue data. the traditional method of distributing library of congress bibliographic information is to provide catalogue cards or proof sheets. these techniques will undoubtedly continue indefinitely into the future, but the rapid spread of automation in libraries has created a new demand for bibliographic information in machine readable form. the original marc project ( 1) was "an experiment to test the feasability of distributing library of congress cataloguing in machine readable form". the use of the word "cataloguing" underlines the essential nature of the marc i project; its end product was a catalogue record on magnetic tape. there is a very significant difference between a catalogue record on magnetic tape and a bibliographic file in machine form. the latter does not necessarily hold anything resembling a catalogue entry, although marc ii still reflects, both in the lc implementation ( 2,3) and in the bnb implementation ( 4,5), a preoccupation with the visual organisation of a catalogue entry. fortunately retention of the cataloguing ''framework" does not hinder the utilisation of lc or bnb marc data in systems designed to hold and exploit bibliographic information, as the whole project is designed as a method for communication between systems. the essence of the marc ii project is that it is a communications system, or a common exchange language between systems wishing to exchange bibliographic information. it is highly undesirable, in fact quite impossible, to plan in terms of direct compatability between systems. machines are different, programs are different, and local objectives are different. the exchange of bibliographic information in any medium implies some level of agreement on the best way to organise and present the data being exchanged. the need to use a fairly standard type of bibliographic structure on a catalogue card is obvious enough, and over the years a form of presentation, as best exemplified by a library of congress catalogue card, has been developed which holds all the essential data and also, by means of typographical distinctions and layout, conveys the information in a visually attractive style. when bibliographic information is transmitted in a machine readable form the question of visual layout does not arise but the question of structure is vitally important. this structure is called the machine format and the machine format holds the data. it literally does not matter in what order the various bits and pieces that make up a catalogue record appear on a magnetic tape. what does matter very much is that the machine should be able to recognise each data element: author, title, series, subject heading, etc. in practice, either each data element must be given an identifying tag that the machine can recognise, or each data element must occupy a predetermined place in the record. in view of the unpredictable nature of bibliographic information, the former methodthat of tag identification-is now widely used and is the technique adopted in the marc system. marc international/ coward 183 the lc and bnb marc systems are two very closely related implementations of a communications format which in its generalised form has been carefully designed to hold any type of bibliographic information. the generalised format description is now being circulated by british standards institute and united states of america standards institute. it can be very briefly described as follows : i leader i directory i control field(s) i data fields the leader is a fixed field of 24 characters, giving the record length, the file status and details of the particular implementation. the directory is a series of entries each containing a tag (which identifies a data field) , the length of the data field in the record, and its starting character position. this directory is a variable field depending on the number of data elements in the record. the control fields consist of a special group of fields for holding the main control number and any subsidiary control data. the data fields are designated for holding bibliographic data. each field may be of any length and may be divided into any number of subfields. a data field may begin with special characters, called indicators, which can be used to supply additional information about the field as a whole. it can be seen that the basis of marc ii is a very flexible file structure designed to hold any type of bibliographic record. once such a level of compatability is established it is possible to prepare general file handling systems ( 6) which will convert any bibliographic record to a local file format. there is certainly much scope for agreement on local file formats as well, but such formats will necessarily be conditioned by the type of machine available and the use to be made of the file. the establishment of a generalised file structure is a great step forward but by itself means very little unless a wide measure of agreement can be reached on the data content of the record to be exchanged. here the responsibility for cooperation and standardisation shifts from the automation specialist to the librarian, and particularly to those national libraries and cataloguing agencies who can by their practical actions assist libraries to implement the standards prepared for the profession. in order to appreciate the real importance of standardisation, particularly in the context of the marc project, it is necessary to look a few years into the future. it is inevitable that the rapid spread of automated systems in libraries will create a demand for machine readable bibliographic records and that in turn will lead to the setting up of bibliographic data banks in machine readable form in national and local centres. these data banks will be international in scope and will contain many millions of items. in the long run the only feasible way to maintain them is for each country or group of countries to develop automated centralised cata184 journal of library automation vol. 2/4 december, 1969 loguing systems for handling their own national outputs and to receive from all other countries involved in the network machine readable records of the latter's national outputs. countries cooperating on this basis must agree on standards of cataloguing (and ultimately on standards of classification and subject indexing), so that the general data bank presents a consistently compiled set of bibliographic data. there is no doubt that national data banks will be set up. libraries today are faced simultaneously with a rapid increase in book prices, a need to maintain ever-increasing book stocks to meet the basic requirements of their readers, and a persistent shortage of trained personnel to catalogue their purchases. these trends are already well established and in the united states, where they are most advanced, the result has been the massive and highly successful shared cataloguing program. historically the shared cataloguing program will probably be seen as the first and last attempt to provide a comprehensive bibliographic service by unilateral action. a large number of countries have cooperated in this attempt but the shared cataloguing program does not rest on the principle of exchange. it is doubtful if even the united states will be able to maintain and extend this programme in its present form. the shared cataloguing program must ultimately be replaced with an international exchange system. national machine readable bibliographic systems will be established, but there is a grave danger that those agencies responsible will be primarily concerned only with the immediate problem of producing records suitable for use in their own national context or for their own national bibliography, regardless of the fact that the libraries and information centres they need to serve are acquiring ever-increasing quantities of foreign material. the exchange principle will be downgraded to an afterthought, a bv-product of the fact that an automated system is being used. if this outcome is to be avoided, international standards must be prepared and national agencies must accept them instead of only paying lip service to them. in the past librarians have tended to be more concerned with codification than standardisation, but in the field of cataloguing at least a great breakthrough was made sixteen years ago when seymour lubetzky produced his "cataloguing rules and principles; a critique of the a.l.a. rules for entry and a proposed design for their revision" ( 7). the work of lubetsky led to the "paris principles" ( 8) published by ifla in 1963 and in due course to the preparation of the "anglo-american cataloguing rules" 1967 ( 9) . these rules, though unfortunately departing from lubetzky's principles in one or two areas provide a solid basis for standardisation. we are fortunate to have them available at such a critical moment in the history of librarianship. they must form the basis of an international marc project. of all the great libraries of the world, the library of congress has done more than any other to promote international cataloguing standards. it is now in a uniquely favourable position to promote these standards marc international/coward 185 through its own marc ii project. the lc marc ii project, together with the bnb marc ii project, can provide the foundation of the international marc network. these projects alone cover the total field of english language material and yet already the basic requirement of standardisation is absent. the library of congress finds itself unable, for administrative reasons, to adopt fully the code of rules it worked so hard to produce and which british librarians virtually accepted as it stood in the interests of international standardisation. that a great library should be in this position is understandable. what is less understandable is that the library of congress should transfer the non-standard cataloguing rules established by an internal administrative decision to prescription of cataloguing data in the machine readable record that it is now issuing on an international basis. one of the great advantages of machine readable records is that they can simultaneously be both standard and non-standard. there is no reason that the library of congress, or any national agency, should not provide for international exchange a standard marc record together with any local information the library might want. if as a result other national agencies are encouraged to do the same, it will not be long before the absurdity and expense of examining each record received via the international network in order to change a standard heading to a local variant, will become apparent. the british national bibliography has already accepted the anglo-american code and by this action has now done much to promote its acceptance in great britain. incomplete acceptance of the code is really the only significant difference between the two marc projects. at a detailed level there are differences in some of the subfield codes. these are chiefly due to the fact that the british marc committee was particularly concerned with the problems of filing bibliographic entries, and as no generally accepted filing code exists it was decided to provide a complete analysis of the fields in headings. this analysis will enable the bnb marc data base to be arranged in different sequences to test the rules now being prepared. the other difference, or extension, in the british marc format is the provision of cross references with each entry, on the assumption that in a marc system a total pack of cataloguing data should be provided. however these differences reflect the experimental nature of the british project, not the fundamental differences in opinion. in this paper an attempt has been made to look at the british and american marc projects not as systems for distributing bibliographic information but as the forerunners of an international bibliographic network. intensive efforts have been made to lay a foundation for this international network. the anglo-american code provides a sound cataloguing base, the generalised communications format provides a machine base, and the standard book numbering system provides an international identification 186 journal of library automation vol. 2/ 4 december, 1969 system. these developments are all part of a general move towards real cooperation in the provision of bibliographic services. they must now be brought together in an international marc network. references i. avram, henriette d.: the marc pilot profect (washington, library of congress: 1968). 2. u. s. library of congress. information

it isn't clear) contract language (identifiable by use of the word "shall"), comments on the language of particular portions of the contract (sometimes labeled "comment " and sometimes not), and cross-references within the book itself (sometimes labeled "note:"). the mixture of different elements-contract language, narrative, etc.-are sometimes confusing. moreover, there are a number of small grammatical garbles which are slightly distracting. a bit of professional editing would make this document both more readable and more useful. third, hegarty focuses on (or uses as an example; it isn't clear) automated circulation systems. this would be very useful if that is what the reader intends to buy. however, with a variety of other turnkey automated systems and sources for libraries on the market or soon to be made available (e.g., acquisitions, book fund accounting, cataloging, online bibliographic access), some language about how the contract should be redesigned or revised to account for different systems and services would have made the book more immediately useful to more readers. last, the book comes as a photocopy of a typed original, with a velo binding. the binding of the reviewer's copy broke apart 320 journal of library automation vol. 14/4 december 1981 the first time it was opened. however, it should be possible to rebind or staple it together if this turns out to be a persistent problem. on balance, for those about to negotiate a contract with a vendor of automated systems and services, the strengths of more loy of contracts probably outweigh the weaknesses. one gets what a contract says one will get;

resulting in computersurban . .. filing before computersurvey. this practice does not follow the traditional library principle "nothing files before something. " the explanation of the idiosyncratic entry arrangement is only given in the preface. when people use a book for quick reference, they usually skip the preface and the introduction; some users will probably miss many terms as a result. the book is international in scope, relatively up-to-date, and informative. english titles published overseas, foreign publishers, and trade fairs and shows pertaining to the computer industry are included in the directory. most titles mentioned have been published since 1970 and many citations are as recent as 1980. the annotations for each entry in "indexing and abstracting resources," "directories, dictionaries, handbooks," and "software resources'' are very informative. it would have been ideal if titles in the "current books" and "computer-related journals" were also annotated to aid users in selecting the materials. subject headings and cross-references used in various sections of the book are not al·ways consistent. for example, in the section "current books," there is a see reference from "a. i. (artificial intelligence)" to "cybernetics/ artificial intelligence/robots," but none from "artificial intelligence." however, in the section "computer-related journals," the heading is "artificial intelligence" with a see also reference to "cybernetics; robots," but no reference from "a.l. (artificial intelligence)." in the "current books" section, "careers/vocational guidance" is used as a subject heading. in the "computer-related journals" section, "employment" becomes the subject. there is no cross reference from either heading to the other in either section. in the "computer-related journals" section, preceding and succeeding titles are linked by cross-references. the history of title changes is outlined whenever applicable under the entries for the current titles. this information is invaluable especially for librarians in identifying variant journal titles. although there are see references under most former titles to current titles, some entries are omitted for previous titles. for example, injosystems was formerly called management and business automation and later changed to business automation with the merging of international business automation and international edition business automation. then there was business automation news analysis edition published book reviews 321 as a supplement to business automation. surprisingly there are no see references under "business automation" and "international edition business automation" to "infosystems." maybe it is because ''business automation" is quite similar to "business automation news analysis edition'' and "international edition business automation" is similar to "international business automation" and would have appeared close together if not adjacent to one another. again some users may miss the links to the current titles. it might have been better to include a separate list for ceased journals. computer science uesources is the result of monumental effort and years of thorough research and careful planning. its compiler and editor, darlene myers has been very active in the computer and information science field, and is the manager of the computing information center at the university of washington. the wealth of information in the book and the currentness of cited materials are the prominent strengths. the flaws mentioned earlier are minor if users read the preface and the introduction in each section first. this reference tool is strongly recommended for computer industry libraries as well as for medium-sized and large public and academic libraries. although more current, it does not wholly supplant ciel carter's guide to reference sources in the computer sciences (new york: macmillan, 1974). carter's entries are all annotated, and some of the citations are not included in the newer work.-frauces lau, blackwell! north america, beaverton,

stanislaus. © 2022. abstract this article provides a background on the migration of the california state university (csu), stanislaus library website from an open-source platform to a content management system specifically designed for library websites. before the migration, there was a trial of different content management systems (cms), a student usability study, and consultations with outside web and systems librarians to acquire better insight on their experiences migrating a library website and their familiarity with the different cms trialed.1 the evaluation process, website design, and usability study began before the pandemic and the global shift to remote services. however, despite this shift, the timeline for the migration was not altered and the migration was completed as planned. within a year, the library website migration planning, designing, trialing, and structural organization was completed using a modified waterfall model approach. background completed under a sudden time limit, the website migration project for the california state university (csu), stanislaus library website is both distinctive and relevant to other libraries who plan to complete a redesign of their website, on both desktop and mobile screens, to meet accessibility requirements under a limited schedule caused by unforeseen circumstances—in this case, a global pandemic and sudden shift to remote work. the website migration project included a reconsideration of the content management system (cms) the library was hosted on. csu stanislaus, surrounded by agricultural landscapes and settled in the central valley, is a hispanic-serving and minority-majority university. ethnic minorities make up 70% of total enrollment and three-fourths of the undergraduates are first-generation students.2 in fall 2021, a little over 8,800 fte (full time equivalent) students were enrolled and total enrollment reached 10,500.3 the university has two campuses, turlock and stockton, and four colleges: the college of science; the college of business administration; the college of arts, humanities and social sciences; and the college of education, kinesiology and social work. the csu stanislaus library website has been designed and redesigned over twenty years for services and content updates, university and library rebranding, and to comply with web accessibility requirements. before the library website migration in 2020, at the start of the covid19 pandemic, the website was developed and produced using the drupal platform (version 7), an open-source cms. the contents of the library website have been updated from time to time since its first years and the website’s front-end design has been modified during the past few years. before the website migration from drupal to springshare llc, the library explored various cms, including wordpress and joomla. initially, staff encountered issues on the former library website hosted on drupal. over the years, the library’s website became difficult to maintain, due to the continuously modified written framework, and to implement new branding across the website’s content and overall theme. mailto:ivargas2@csustan.edu information technology and libraries december 2022 a library website migration | ochoa 2 the objective of the website migration project was to effectively enhance the website’s interface for usability and to meet current standards and guidelines for accessibility. additionally, the university was set to launch a new design of the institutional website, which required that the library emulate the university website’s design for uniformity. in preparation for the university website redesign, it was necessary for the library to model the new university design, explore cms, and migrate the library website. a possible migration from drupal 7 to drupal 8 was investigated from 2017 to 2018, when the former web services librarian was in the process of redesigning the website; however, the redesign and migration was not completed. it was discovered around the same time that editing or upgrading the initial design and development of the library website, which utilized a community developed design heavily customized over the years, would make the migration extremely difficult. any editing that triggered modification of the locally customized theme caused other elements of the website to break or collapse, particularly the website’s layout design, including the header, footer, and menu. it quickly became apparent that it would be more sensible to begin the redesign of the website infrastructure on a platform starting from scratch. a new design would also facilitate the application of the latest accessibility and usability standards. a complete rebuild would also afford the library the option to consider other web management platforms. this would evidently be a challenging feat. so, a modified version of the waterfall model was adopted. for this migration, a simple cascading approach was chosen as it worked best with the natural flow of the library’s planned migration. the waterfall model consists of the following objective processes: requirement analysis, design, construction, acceptance testing, and transition .4 for the planned migration, the requirement analysis was confirming that i would have a local and cloud server available for trialing the cms and developing a website design. the design and construction processes would be complete when the new website design was created, the cms trials were finalized, and outside web services and systems librarians were consulted. the testing phase would be complete when the student usability studies were concluded. as explored in my previous article, “navigation design and library terminology,” a user-centered usability study was conducted to assist in the library website redesign and create the website prototype. the prototype was designed to assess the library website’s front-end elements as well as the layout theme and overall design. lastly, the transition, or migration process, would be the final planned objective in the approach. as the web services librarian, i worked as the website migration project manager. the project manager migrated the final and redesigned library website and website content, conducted the student usability studies, tested the cms and created a cms recommendation for the library, and consulted with outside librarians on their experience migrating a website and using drupal or springshare as their library website cms. timeline and an unexpected pandemic the cms trials began in fall 2019 and continued until summer 2020. the former library website used drupal 7, so drupal 8 and springhare’s libguides cms were set to be trialed. the trials consisted of developing and designing a new library website on the platforms. experiences were documented and the design process was recorded for analysis and comparison information technology and libraries december 2022 a library website migration | ochoa 3 of the platforms. this information was used to determine which platform would best support the new website. consultations were also sought from various web services librarians, system librarians, and information technology professionals. table 1. timeline of the website migration

website. drupal was used for more than two decades and consideration was given to upgrading to the latest version of the platform, drupal 8. springshare libguides cms was trialed as library staff and faculty were already familiar with libguides and subscribed to several other springshare applications, including libanswers and libchat for virtual research consultations, libcal for reserving library spaces, and libinsight for user analytics. trialing of libguides cms began in fall 2019. a website prototype (design, theme, homepage) was developed and designed using the platform. the platform was analyzed and explored heavily since it was a platform that had not been previously utilized by our library. libguides cms offers unlimited advanced customized groups. features like publishing workflow management, discussion boards, internal sites, various account types, password protections , and ip restrictions, and courseware integration via lti, were also researched during the test. in terms of content creation and maintenance, there were limitations under libguides cms. libguides cms has a built-in framework, ideal for libraries, with default settings that may disrupt or limit complex customization. at the time of the trial, additional support from springshare was needed to override default settings. also, libguides cms, compared to drupal, did not provide an option for tracking revisions on guides and content. drupal, a highly programmable free open-source website platform, was the previous platform the library website was hosted on. like all upgrades, drupal 8 offered a series of new features and improvements, from framework to themes. as a highly programmable platform, it requires information technology and libraries december 2022 a library website migration | ochoa 4 mindful designing and programming to establish the infrastructure and design. drupal 8 was tested and trialed on a development site in february 2020. the development site on drupal was utilized for the final evaluation of the cms. when the campus was ordered to partially close in march 2020, the home page and foundational design were completed; however, the development site was inaccessible remotely due to a block by the campus firewall. the development site resided on a protected local server on campus, and special permissions were required for remote access. unfortunately, i was not granted the special permissions required in due time, so the development site on drupal was put on hold. based on projections after creating a foundational design in february 2020, it would have taken about six months to complete the overall website design. remotely, i continued the drupal 8 evaluation, considered the results of librarian consultations and the literature on drupal as a cms. consultations and cms comparisons generally, the difference observed between both platforms is that libguides cms is a content management system primarily designed and maintained for library websites, whereas drupal is a framework for all sites, including highly customized websites. to support the cms comparisons, six web services and system librarians were consulted prior to the migration. the librarians were from distinct institutions: two community colleges and four 4year universities ranging from 2,000 enrolled students to 30,000 enrolled students, and library departments from 10 to over 200 library personnel. a systems librarian from a university of about 2,000 enrolled undergraduate students, regarding their experience migrating their website from drupal to libguides cms, shared that, “[their migration] took a couple months . . . we worked with campus it and springshare to ‘flip the switch’.” a digital services librarian from a university of over 10,000 enrolled students explained, “the entire transition probably took about 6–8 months.” the time to migrate a library website would depend on the size of the website, which was also influenced by the size of the campus. with more than 10,000 students, the csu stanislaus library website migration project was scheduled to be completed by the end of the summer semester, from june 2020 to august 2020. creating a new website from scratch on drupal proved to be a longer process than creating a new website on libguides cms. a systems librarian explained that “[libguides cms] is also quite streamlined compared to trying to maintain a more complex platform like drupal, which makes it a bit easier for librarians who are not full-time professional coders.” still, libguides cms is not as robust and did not offer the level of customized creation that drupal offered for general websites. the systems librarian added that although it is helpful to have a web services or systems librarian who can code full time, “turnover happens and some libraries can’t be sure there will always be someone on hand who is comfortable doing that coding.” ideally, having a full-time programmer is valuable for any library managing their own website; however, it is currently not the case for our university library. a user interface developer from a university of over 30,000 enrolled undergraduate students described their experience using a large amount of css to override default settings in libguides cms. they explained, “we have a large amount of overriding css, not to mention that it makes [it] messy. when building a site [in libguides] you can do whatever you want as long as you know where to put your code, utilize the js libraries springshare uses, implement css to override their information technology and libraries december 2022 a library website migration | ochoa 5 system default items/styles and use their api.” before finalizing our migration, we were required to contact the springshare technical support team to override default settings in libguides cms. however, the default settings are implemented to guide nonprogramming librarians when creating web content. a web services librarian from a university with 2,000 undergraduate students enrolled stated, “i don't think [libguides cms] will be anything like a drupal or wordpress cms. but, i do believe that their software is the perfect niche for libraries and librarians.” libguides cms required getting used to as csu stanislaus library staff were accustomed to hosting the website on a cms that allowed file transfer protocol (ftp). as a systems librarian explained, it can be difficult to organize a large amount of coding in libguides cms since “you don’t get your own server that you can configure and use for things like ftp storage.” the experiences shared by librarians were similar throughout our process for creating the new site and design, and these consultations in particular were not only insightful but helped prepare for and organize the structure of the website before actually migrating the content. an additional component considered before choosing a cms was the technical support and server options available for each. libguides cms is cloud-based and hosted by springshare, which currently uses amazon web services (aws). upgrades are implemented by springshare overnight, as well as minute-by-minute base backups. for the most part, systems and web librarians were satisfied with springshare technical support to implement these changes. with drupal, the institution can choose whether to host their site on a cloud or local server. during our migration in summer 2020, we sought assistance from springshare technical support to modify security certificates and custom domain names. if a site is hosted on drupal, the librarian can implement security certificates and update custom name domains without having to contact the drupal technical support team. it is fundamental for a library to consider these features as well, especially if under a set timeline. these consultations with developers and with systems and web librarians aided in the understanding of what libguides cms and drupal offered based on general comparisons, programming, customization, and technical support. cms accessibility compliance the accessibility levels of each cms also supported the final decision of the chosen cms. according to the web content accessibility guidelines (wcag), there are three levels of accessibility conformance: a (lowest), aa (midrange), and aaa (highest).7 currently, the target level of accessibility for csu campus websites is aa, which also includes all the guidelines found under conformance a. regardless of the foundational framework for both libguides cms and drupal, it was determined after exploring accessibility on these cms that developers should regularly test the design and content customization for accessibility. ultimately, the accessibility levels of a library website and its mobile responsiveness are dependent on the local management and develo pment of the sites. website design: usability study concurrent to the consultations, trials, and design development, a usability study was conducted in february 2020 with a total of 38 university student participants, including undergraduate information technology and libraries december 2022 a library website migration | ochoa 6 students, from freshman to seniors, and graduate students. the usability study was organized to test the website navigation design prototype that was built and used during the cms trials. students’ feedback would guide the decision of whether to design an audience-based navigation menu or a topic-based navigation menu. the study was conducted in a closed and monitored library room with laptops prepared. students were asked to answer questions and complete tasks to test the website design prototype menu navigation design. each student’s actions were recorded through screen recordings and visual observation, while assigning numbers to students to ensure anonymity, e.g., student 1, student 2, etc. the following seven tasks were used for the student usability study: 1. find research help on citing legal documents—a california statute—in apa style citation. 2. find the library hours during spring break. 3. find information on the library study spaces hours and location. 4. you’re a student at the stanislaus state stockton campus and you need to request a book from turlock to be sent to stockton. fill out the request-a-book form. 5. you are a graduate student and you need to submit your thesis online. fill out the thesis submission form. 6. for your history class, you need to find information on the university’s history in the university archives and special collections. find information on the university archives and special collections. 7. find any article on salmon migration in portland, or. you need to print it, email it to yourself, and you also need the article cited. during each study, students’ actions were screen recorded using snagit, screen capture and screen recording software installed on the laptops. data collected included the ease of access in terms of navigation behavior, the number of clicks, web pages visited, and the time it took for students to complete each of the seven tasks. that data was recorded and analyzed from the anonymously saved screen recorded videos. students were also asked to answer questions at the end of the study in the form of a written survey, which was then collected and utilized to support the final decision of the outcome of the prototype design. the results of the usability study provided the library with a variety of outcomes and several elements were integrated to lead the redesign of the library website’s header and main menu. the results of the study showed that the prototype’s design navigation, an audience-based navigation, was not as user friendly as predicted; therefore, the library website prototype design would need to be edited and modified to revert to the current navigation design of the existing website, which is a topic-based navigation. students had difficulties with the audience-based navigation design since it required them to select an “audience type” under the menu (fig. 1). their selection was determined by assessing where they believed the information was found. since most students did not understand the structure of the website, they did not know how to utilize the audience-based navigation to complete the seven tasks. although they found that the navigation design of the website was clear and simple, it required a “getting used to.” information technology and libraries december 2022 a library website migration | ochoa 7 the results also highlighted the effects of the use of library terms. to make menu links exceptionally user friendly, clear and common terminology was added. an additional component was a search-all search box for the website, which was advocated by the student participants. based on navigation results, the main menu and submenus were also structured to not only be clear and organized, but for popular pages to be mapped and linked in more than one menu. figure 1. screenshot of the audience-based navigation design developed for the library website prototype. figure 2. screenshot of the topic-based navigation in the former library website. the design structure of the website relied on the organization and management of the website pages. to maintain a congruent structure, it was necessary to choose a navigation design that met the needs of our students. in this case, the results determined that the topic-based navigation was preferred; thus, the management of website pages and submenus was modified to fit this navigation. the usability study was focused on testing the navigation design of the website and the navigation main menu. given the helpful feedback from users and having more participants than expected, it would have been beneficial to also test other aspects of the website in this study. the home page is the landing point and statistically the most visited web page of the library’s website. it is the hotspot for students and our university’s community to find the catalog, resources to fulfill their research needs, upcoming news and events, the reservation platform, and more. however, as the website redesign progressed, there were challenges in designing the primary components of the website home page, such as assessing what elements were fundamental to have on the library website, following web accessibility requirements, and following the university website’s new theme and design. ultimately, the components of the former library website’s home page were migrated in its similar structure to the redesigned information technology and libraries december 2022 a library website migration | ochoa 8 website. yet, adding questions and tasks on the usability of the library home page and its content components would have certainly aided in not only the redesign and migration, bu t the direction of the library website’s future development. this information will be a focal point for future usability studies of the library’s website. the final migration the greatest challenge throughout the project was the time constraint due to the covid-19 pandemic. because the pandemic brought several unforeseen obstacles into staff work schedules, it was challenging to manage the time needed to complete the project and simultaneously work around tasks surfaced by the pandemic. however, staff committed to stay on schedule and to complete the migration project before the start of the fall semester despite the circumstances. after transitioning to remote library services, emphasis was placed on developing the website and web content. even more so, the migration project served to ensure that the library was providing an enhanced and accessible desktop and mobile website for users who were now working from home. additionally, this included the management of web services, on top of the migration project. a concise and organized schedule was necessary and although time management of the different projects and tasks offset by the pandemic was challenging, the web services librarian was fortunate to have support from the library information technology staff. after the cms trials and after the website prototype usability study, libguides cms was chosen as the content management system for the university library website. because the library was looking for an easy-to-use platform, utilizing libguides cms reduced the time needed to build an infrastructure and allowed simple website content management, maintenance, and an improvement over the former website’s accessibility and mobile responsiveness. the platform worked well for the campus and the library; however, each library should evaluate its respective department priorities, along with what is expected, desired, and needed for their individual library website to successfully showcase services and programs to users. following a modified waterfall model approach proved to be a success for the website migration project due to existing resources and scheduled timeline for implementation. in a future virtual renovation or redesign of the library website, the library will explore various project planning models pertinent to the future proposal’s desired outcomes.

libraries have traditionally turned to google analytics for data collection to gain insights into the usage of their web properties. as the valuable field of data analytics continues to grow, concerns about user privacy rise as well, especially when discussing a technology giant like google. in this article, the authors explore the feasibility of using matomo, a free and open-source software application, for web analytics in their library’s discovery layer. matomo is a web analytics platform designed around user-privacy assurances. this article details the installation process, makes comparisons between matomo and google analytics, and describes how an open-source analytics platform works within a library-specific application, ebsco’s discovery service. introduction in their 2016 article from the serials librarian, adam chandler and melissa wallace summarized concerns with google analytics (ga) by reinforcing how “reader privacy is one of the core tenets of librarianship.”1 for that reason alone, chandler and wallace worked to implement and test piwik (now known as matomo) on the library sites at cornell university. taking a cue from chandler and wallace, the authors of this paper sought out an analytics solution that was robust and private, that could easily work within their discovery interface, and provide the same data as their current analytics and discovery service implementation. this paper will expand on some of the concerns from the 2016 wallace and chandler article, make comparisons, and provide installation details for other libraries. libraries typically use ga to support data-informed decisions or build discussions on how users interact with library websites. the goal of this pilot project was to determine the similarities between google analytics and matomo, how viable matomo might be as a google analytics replacement, and seek to bring awareness to privacy concerns in the library. matomo could easily be installed on multiple websites. however, this project looked into a specific instance of monitoring, that of the library’s discovery layer, ebsco discovery service (eds). literature review google analytics the 2005 release of google analytics was a massive boon to libraries who long searched for an easy to implement and budget-friendly tool for analytics. shortly after its release, academic libraries were quick to adopt the platform and install its javascript code into their library web pages.2 in a little over a decade, there have been nearly forty scholarly articles published that discuss the ways in which google analytics is used for libraries’ websites. articles that not only mailto:denise.quintel@mtsu.edu mailto:robert.wilson@mtsu.edu information technology and libraries september 2020 analytics and privacy | quintel and wilson 2 introduced the service, but also discuss the various ways libraries utilize the platform.3 in fact, in their survey of 279 libraries, o’brien et al.’s 2018 research found that 88 percent of libraries surveyed had implemented google analytics or google tag manager.4 in contrast, during that same period, authors found matomo, or its earlier name, piwik, discussed in a total of five scholarly articles, with only three libraries who wrote about using it as a web analytics tool.5 in addition to measuring website use, libraries found that google analytics allowed for several different assessments. in using google analytics, libraries could provide immediate feedback for projects, indicate website design change possibilities, create key performance indicators, and determine research paths and user behaviors.6 convenience of implementation and use, minimal cost, and a user-friendly interface were all reasons cited for the widespread and fast adoption.7 although the early literature covers a lot of ground about the reporting possibilities and the coverage of google analytics, there is rarely a mention of user privacy. early articles that mention privacy provide a cursory discussion, reiterating that the data collected by google is anonymous and therefore, protects the privacy of the user. recently, there has been a shift in literature, with articles that now provide more in-depth discussions about user privacy and the concerns libraries have with third parties that collect and host user data. o’brien et. al discussed the problematic ways that libraries adopted and implemented ga, by either overlooking front-facing policies or implementing it without the consent of their users.8 in their webometrics study, o’brien et. al found that very few libraries (1 percent) had implemented https with the ga tracking code, only 14 percent had used ip anonymization, and not a single site utilized both features.9 the concern is not solely google’s control of the data, but in google’s involvement with third-party trackers. third parties, as pekala remarks, are rarely held accountable.10 with an advertisement revenue of $134 billion in 2019, representing 84 percent of its total revenue, it is important to remember that google is an advertising company.11 google's search engine monetization transformed it into one of the world's most recognizable brands. as the most visited site in the world, google is firmly committed to security, especially when it comes to data theft. google offers protection from unwanted access into user accounts, even providing ways for high-risk users, such as journalists or political campaigns, to purchase additional security keys for advanced protection.12 but while google keeps data breaches and hackers at bay, the user data that google collects and stores for advertising revenue tells a different story. goo gle stores user data for months on end; only after nine months is advertisement data anonymized by removing parts of ip addresses. then, after 18 months, google will finally delete stored cookie information.13 recent surveys are reporting an increase in users who want to know how companies are collecting information to provide data-driven services. in a 2019 pew research survey, 62 percent of respondents believe it is impossible to go through their daily lives untracked by companies. additionally, even with the ease that certain data-driven services bring, “81 [percent] of the public reported that the potential risks they face because of data collection by companies outweigh the benefits.”14 cisco technologies, in a 2019 personal data survey, found a segment of the population (32 percent) that not only cares about data privacy and wants control of their data, but has also taken steps to switch providers, or companies, based on their data policies. 15 additionally, in pew research survey results published as recently as april 2020, andrew perrin reports that an even larger number of u.s. adults (52 percent) are now choosing to not use products or services information technology and libraries september 2020 analytics and privacy | quintel and wilson 3 out of concerns for their privacy and the personal information companies collect. 16 with a growing population of users who make inquiries about who, or what, is in control of their data, a web analytics tool that can easily answer those questions might serve libraries, and their users, well. comparisons google analytics had been the library’s only web analytics tool until the start of the pilot project. during the pilot period, the authors simultaneously ran both analytics tools. once matomo was installed the authors found several similarities between the two products, and discovered that nearly identical analyses could occur, given the quality and quantity of the data collected. the pilot study focused only on one analytics project, which would be the library’s discovery layer— ebsco’s discovery service. authors worked with their dedicated ebsco engineer to replicate the google analytics eds widget, and have it configured to send output to matomo instead. in making comparisons, one of the common statements about ga and matomo, is that the numbers will never be exact matches. oftentimes with much higher counts presented in ga than in matomo. several forums and blogs, even matomo themselves, admit that there are several possible reasons why there is a noticeable difference between the two.17 those involved in the discussion theorize that this is due to ga spam hits, bot hits, and matomo’s ability for users to limit tracking. beyond the counts, both products measure the same kinds of metrics for websites.18 for this project, the authors only wanted to look at specific metrics within eds, those measurements that look more closely at the user, rather than the larger aggregate data. for the sake of the analysis, it is important to note that although both products have several great features; this is a specific situation where the researchers use certain features in terms of analytics. the analytics we collect for eds strive to answer specific questions: • are users searching for known item or exploratory searches? how often? • are users utilizing the facets and limiters? how often? although you can use both products to count page views or set events for your website, when looking at meaningful metrics for our discovery system, we focus more on the user level. in google analytics, the best way to capture these is by going through the user explorer tool, which breaks up a user journey into search terms, events, and actions that occur during sessions. in the same way, matomo provides anonymized user profiles that include search terms, events, and actions in its visits log report. in ga, you can export this user explorer data in json format, but only at one user at a time, as seen in figure 1. this restriction also means you cannot see data from multiple users, with those details, on a single page. to contrast, in matomo’s visits log, you can export the same data (search terms, events, actions) from multiple users in csv, xml, php, tsv, json, or html formats. as seen in figure 2, matomo offers a snapshot of this data in an easy-to-read single page, versus google’s one user at a time option which requires clicking through to see a user report. information technology and libraries september 2020 analytics and privacy | quintel and wilson 4 figure 1. screenshot of the google analytics user explorer tool figure 2. screenshot of the matomo visits log report information technology and libraries september 2020 analytics and privacy | quintel and wilson 5 in summary, libraries using either of these analytics tools can measure usage and users with page views, visits, and unique visitors. looking at how users navigate a site is possible with the available user paths, from the initial search, to events as seen in figures 3 and 4, and an exit page url. goals can be set and maintained with conversion metrics tied to referrers, visits, user location, devices, or user attributes. like google analytics, matomo can run reports on engagement and performance, and share customizable user-friendly graphs or graphs or other visual representation. figure 3. peer reviewed limiter as event action in google analytics figure 4. peer reviewed limiter use as event name in matomo comparisons on privacy both google analytics and matomo offer ways to protect the privacy of your users. both offer ip anonymization, the option for data deletion after a certain time, and both provide do not track feature for users. it is important to note the way google offers these adjustments to the user. for matomo, do not track is a default behavior, meaning that the tracker automatically honors a browser’s settings for all sites, which is sometimes not the case, as respecting the do not track browser setting is voluntary for websites, not mandatory .19 google analytics offers the same service, as long as it is implemented by the user through a browser extension.20 ip anonymization and data deletion are all features that matomo users can adjust easily from the dashboard, whereas google analytics users will need to make those adjustments programmatically. 21 in matomo, you can choose to automatically delete your old visitor logs from the database, although matomo recommends keeping detailed matomo logs from three to six months, and then information technology and libraries september 2020 analytics and privacy | quintel and wilson 6 delete the older log data.22 quite the contrast is google analytics where a user makes a data deletion request to google, which then creates a report for your review, before submitting the request to google. even after submitting a request, google still allows for seven days to reverse that decision. in terms of data retention, google analytics gives you the option to retain user data anywhere from 14 months to 50 months, with the option to never expire. fourteen months is the shortest amount of time you can retain user data for, nothing less.23 ip anonymization is the default for matomo analytics but is an opt-in feature for google analytics. again, like data retention, any adjustments to ip anonymization in matomo can occur in the dashboard with options to have two or three bytes removed from the address. google analytics will adjust the last octet to zero.24 both products are similar in several ways, but the standout feature of matomo is that the data belongs only to your institution. in his interview with katherine schwab for fast company, mathieu aubry, matomo’s founder states it clearly: when [google] released google analytics, [it] was obvious to me that a certain percent of the world would want the same technology, but decentralized, where it’s not provided by a centralized corporation and you’re not dependent on them… if you use it on your own server, it’s impossible for us to get any data from it.25 implementation and installation originally released as piwik in 2007, matomo was designed as a replacement to phpmyvisites.26 it is an open-source software application licensed under gnu gpl v3.27 it is designed as a php/mysql application allowing the server operating system (os) and web service to best match a user’s needs or institutional preferences and expertise.28 to match the organization’s preferences and expertise, this matomo instance was set up as a linux-apache-mysql/php (lamp) stack server (centos 7 in our case) with apache 2.4.6 and mysql-mariadb 5.5.60. the required configurations needed to run matomo are well-documented on the matomo documentation site as well as the download and documentation area. depending on the version of matomo, the mileage a user gets with the documentation may vary. for example, on the recent upgrade to 3.11.0, the instance displayed a warning notification that php v7.0 had reached end of life and recommended updating to php v7.1 or greater to accommodate future matomo versions. however, at the time of this writing, the minimum php version required stated in matomo’s documentation is 5.5.9 or greater.29 like many php applications, once the prerequisite applications are installed (php, mysql, and the selected web service, apache in this case), the matomo install is completed by browsing to the server’s url or ip address on port 80. browsing to the index.php path in a web browser will guide a user through the install process. the installer will also review file directories on the server and inform a user of any permissions problems that will need to be addressed for correct install and use. compared to other php application install experiences, installing matomo was straightforward and easier to follow than many. within a few minutes, the admin user was created and the first website was added. the web-based administration area is also more robust and easier to use than many comparable applications. many features that might typically require configuration file changes directly on the server, including matomo upgrades, can be configured through the administration area. while the administration page has many options relating to paid-for premium features, there are several information technology and libraries september 2020 analytics and privacy | quintel and wilson 7 particularly helpful free configuration cards in the interface. most notably is the “system summary” card that displays the current version of matomo, php, and mysql as well as total users, segments, goals, tracking failures, total websites configured, and a few other metrics. there is a “tracking failures” card that notifies of issues with websites, and a “need help?” card that links to the matomo community forums. finally, the “system check” card displays any warnings or errors as well as a link to the full system check report. this is extremely helpful when matomo has been installed but the instance still needs additional configuration changes or follow-up tasks on upgrades. if there are warnings or errors, the full system report will often have recommendations of changes to make either in the administration page or on the server in the configuration files. these administration features make maintenance a straightforward process. since setting up the server, two upgrades have been completed. in both cases, an email notification was received indicating a new stable release was available. on login to matomo, this information also appeared as a banner. simply clicking on the download update option automatically updated the service without any need to access the server directly or via ssh. in both cases the updates ran smoothly with one exception. in that case, several files were created or overwritten with the root user as the owner. as a result, matomo indicated an issue with the files and/or path not being found. in actuality, the files did exist, but matomo no longer had permission to read them. resolution of the problem required browsing to the directory path indicated in a warning on the server and changing ownership from the root user to the apache user to match other files. despite this issue, the update process is much more user-friendly than similarly structured applications. standalone implementation and installation of matomo is made simple by the installation documentation that is readily available on the matomo.com website, especially if one is familiar with php/mysql applications. adding one or two websites whose architectures a new matomo user is well-acquainted with is a good way for new users to pilot and get introduced to matomo’s overall functions without being so overwhelmed that the more granular functions are never learned. a system admin may find maintenance and updates to this service less problematic with less interruption of the service than similarly structured applications while users may find the overall functionality of matomo easier to use and finer points of reporting and analytics more transparent and easier to understand than google analytics. once installed, the authors then tested matomo on a low-traffic library site. after tracking proved successful, eds was entered as a new website in the matomo dashboard and the javascript tracking tag was placed in the bottom branding of eds. the process of adding eds as a new site to matomo was as easy as expected, and the data collection was almost immediate. to mirror the eds and google analytics integration, the authors worked with their ebsco library service engineer to create a matomo widget. luckily, another engineer had previously worked on an integration when it was known as piwik. instead of building from the ground up, the piwik widget only needed clean and updated code to match the google analytics widget, which would allow for the tracking of events and site searches. adding a user outside of the organization to matomo was necessary for the ebsco engineer to fine-tune the widget. matomo admins can set up users with specific permissions within the system, with access to only a specific site. each matomo user has their own email address and password (not domain-specific), settings, and users can even customize their dashboard. after information technology and libraries september 2020 analytics and privacy | quintel and wilson 8 testing proved successful, the new matomo widget moved into the live profile of eds, and data collection commenced. security though the service is in a pilot stage with limited data collection, the authors wanted to ensure an ssl certificate was in place for login to matomo. with eff’s certbot (https://certbot.eff.org/), the authors installed a let’s encrypt (https://letsencrypt.org/) ssl certificate. the ssl certificate is automatically renewed every three months via a cronjob on our server. because of the power of the administration interface, caution should be used when assigning the “super user” role to user accounts. it would also be wise to require two-factor authentication (2fa) on the service. turning on 2fa is a very simple process and matomo works with multiple third-party authentication utilities including authy, lastpass, and 1password. while each user can choose to activate 2fa, an admin can require it for all users if desired. conclusion as the amount of research and rate of adoption testifies, since 2005 ga has set the benchmark for assessment of library web asset success and has made possible a completely new understanding of the library user experience and overall assessment of library services. matomo’s earliest iteration appeared shortly after in 2007 and is a viable alternative to proprietary web analytics applications with a few notable advantages over ga. from a long-term perspective, the two biggest advantages of matomo is that it is licensed under a copyleft gpl free and open source software (foss) license and is designed with user privacy at heart. for libraries, using foss applications whenever possible allows them to practice what they preach. foss does not mean cost-free. in fact, free in the foss sense is more akin to freedom (freedom to download, modify, distribute, and change the code) rather than free of charge. budgeting for a hosted subscription, support, or the costs of a library running and maintaining the application itself or through an infrastructure as a service (iaas) provider like amazon web services (aws) or microsoft’s azure is necessary, but the freedom matomo provides by ensuring the library is in control of its patron data, that it is protected, and that data is not at risk of becoming a product in and of itself may well be worth the cost. like other initiatives in the open-access movement or open-education resources, and as thirdparty data collection and privacy on the web becomes a more mainstream concern, opting to use matomo to protect patron privacy principles allows libraries to be the leaders on issues relating to privacy and intellectual freedom. as noted earlier, there are other feature-based advantages matomo provides that impact the day-to-day aspects of monitoring web asset use and assessment, like export options and viewing the full log of visits. lastly, by focusing on eds in this pilot, the authors were able to demonstrate and verify that matomo rises to the challenge not just with traditional web asset analytics requirements, but to library-specific applications like proprietary discovery layer services.

lib-mocs-kmc364-20131012113204 190 communications automation and the service attitudes of arl circulation managers james r. martin: university of rochester library, rochester, new york. the circulation function in our large academic libraries has undergone two important transformations since the turn of the century. the first of these is departmentalization; the second, automation. the departmentalization of the circulation function has tended to separate the circulation department from the library's educational and information functions , the more "professional " aspects of librarianship. laurence miller makes this point in his dissertation, "changing patterns of circulation services in university libraries, " which focuses on the rise of circulation departmentalization.1 miller surveyed large academic libraries to determine if certain services-reference, interlibrary loan, orientation, catalog assistance-were being withdrawn from the circulation function . after verifying a withdrawal of these services and identifying them as the "professional" ones, miller drew the conclusion that circulation is therefore suspect as a professional activity. 2 his are generally held conclusions as robert oram suggests: until recently, librarians have been reluctant to deal with circulation problems on an organized basis. the belief that circulation was, in part at least, custodial and clerical rather than managerial and professional underlies much of the reluctance to solve mutual circulation problems th rough a professional group.' paralleling this change in the circulation function's organizational setting, the mechanization of the circulation process has continued to move from the laborious and slow use of manual procedures and book cards toward the immediate updating and record keeping of the online system. circulation automation has passed from the early days of simply mechanizing files (represented by the batch system) to the present, where libraries have the potential capacity to perform the complete circulation control process with real-time systems. • sophisticated online systems have begun to truly control the complete circulation function. the metamorphosis of circulation automationfrom simple mechanization to full computerization-has had a tremendous impact on the technical side, the processes, of the circulation department. likewise it may well have had impact on the service attitudes, priorities, and leadership of the department. the level of automation may relate to the circulation manager's attitudes and priorities, and in the words of an american library association committee, "the impact of automation might change the image of the circulation librarian." 5 as it automates, gaining control over its own processes, the circulation department and its manager may actually become more responsive to its users-more service oriented, more "professional." in february 1980, a questionnaire was sent to circulation managers of all the ninety-eight academic libraries that hold membership in the association of research libraries. 6 it sought to (1) identify the degree and state of automation of the circulation function , classified by the three system categories of manual , batch , and online systems, and (2) to capture opinions on the circulation manager's view of his management role and his attitudes on service issues and user demands. these attitudes were related to the three types of systems. seventy-six questionnaires were returned, for a 78 percent response rate. circulation department characteristics circulation departments ranged in size from 4 to 78 ite employees. the average department size was 18, the median 14.25. the number of students employed ranged from 0 to 175. twenty-nine percent of managers said staffing was not adequate and 45 percent said they had to depend too heavily upon students. fifty-seven percent of managers of manual systems responded that they had to depend too heavily upon students, versus 27 percent of batch and 50 percent of online managers. (because of variations in what is counted, transaction volume figures are not particularly informative.) circulation system characteristics the seventy-six responding libraries reported approximately thirty-two different system configurations. thirty-nine percent of these systems were manual, 34 percent were batch, and 26 percent were online. nineteen percent of the total were manual mcbee systems and 15 percent were libs100 online systems. manual systems had been in use an average of twenty-six years, batch systems an average of eight years (range: ten months to eighteen years), and online systems an average of three years (range: three months to eight years). circulation manager characteristics typically, the circulation manager in an arl library is the head of a department. arl circulation managers had held their positions from six months to twenty years. five years was the average, but 68 percent listed five years or less. gender was evenly distributed: thirty-eight males and thirtyeight females. the managers of manual systems were 43 percent male/ 57 percent female, those of batch systems were 54 percent male/46 percent female, and of online systems 55 percent male/45 percent female. seventy percent of all managers had an mls, and 30 percent did not; 40 percent of managers of online systems did not have an mls. a majority of circulation mancommunications 191 agers (57 percent) reported spending over 25 percent of their time on matters outside of strictly circulation concerns. in fact a substantial minority, 23 percent of all managers, spent over 50 percent on extracirculation matters. satisfaction with circulation system as a group, arl circulation managers are not satisfied with their systems, as table 1 shows. online-system managers consistently rate their systems most highly. asked if their systems were "close to ideal," only 17 percent of all respondents were affirmative. only 3 percent of manual-system managers agreed that their system was "close to ideal" as compared to 12 percent of batch managers and 45 percent of online managers. hidden in these averages is the fact that three managers gave their systems perfect scores on all four questions and those systems were all online: geac, libsloo, and an ibm-based online system. (table 2 summarizes responses on the four system-performance statements.) hardware, software, and downtime circulation managers with automated systems also reported on their experience with equipment, software, and downtime. batch-system managers were more satisfied with hardware and software (7 4 percent for both) than were online managers (60 percent satisfied with hardware and 65 percent with software). however, open-ended questions revealed that dissatisfaction with online-system hardware and software centered around limitations of the libs100 system (used by 55 percent of online-system managers). the libs100 system was panned for "inflexible software," "poor fines system," and "lack of reserve book features. " (these are all long-recognized limitations that were partially addressed in the relatively recent release 24.) the downtime situation was more satisfactory, however, for online managers than batch managers. seventy-five percent reported downtime was not a problem as against more than 63 percent of batch-system managers. 192 journal of library automation vol. 14/3 september 1981 table 1.

agree," "agree," "no opinion," "disagree," and "strongly disagree." attitude statements fell into four categories: (1) specific service concerns, (2) the importance of the managerial role, (3) user problems, contacts and complaints, and (4) user demands and expectations. the averages of the last three groups were used to explore the question of association between level of automation and manager service attitudes (see table 3). specific service concerns ninety percent of circulation managers agreed that "speed of service is very important to users," and no online-system manager disagreed. forty-three percent of manual-system managers agreed that "control of circulating books tends to be inadequate." this compares to 16 percent of batch managers and 15 percent of onlinesystem managers. asked whether "users tend to expect more service than the department can give," 56 percent of manual managers agreed, as did 46 percent of batch managers and 40 percent of online-system managers. attitudes toward management role the study found that circulation managers are uniformly strong in their affirmation of the importance of their role, with a slight tendency for online managers to be more affirmative. in fact, 100 percent of respondents agreed with the statement that the "management of the circulation function is important." ninety-three percent agreed that "circulation management should rank high among the library's priorities." ninety-five percent disagreed with the negative statement that "circulation communications 193 table 3. attitude responses, averages management role

response. management offers little opportunity for the exercise of initiative." ninety-four percent of all managers disagreed that "circulation management lacks complexity." attitudes toward user problems, contacts, and complaints the study found that circulation managers are uniformly strong in their desire to respond to user complaints and problems, but with a slight tendency for online managers to be more favorable to the user. one hundred percent of online managers regarded user contacts as pleasant, as did 93 percent of manual and batch managers. ninety-five percent of online managers, 92 percent of batch managers, and 87 percent of manual managers affirm that patron contact provides the challenge in circulation work. eighty percent of online managers and 73 percent of manual and batch managers rejected the statement that "complaints tend to be unfounded." sixty-five percent of the respondents of online systems were more likely to favor the user by thinking "complaints are most often substantive," as compared to 50 percent of manual managers and 48 percent of batch managers. ninety percent of online managers disagreed that users "complain far too much," compared with 84 percent of batch managers and 79 percent of manual managers. attitudes toward user demands and expectations circulation managers are generally favorable in their attitudes toward user demands and expectations. several statements in this area, however, ran contrary to the tendency of online managers to agree slightly more with attitudes favorable to the user than managers of batch and manual 3.48 3.52 3.46 3.88 3.9 4.03 systems. for example, while 93 percent of manual-system managers and 85 percent of batch managers agreed that "the circulation department should be oriented towards users' expectations," only 70 percent of online managers did. on the statement, "users should be more tolerant of limitations in circulation services," manual managers disagreed by 34 percent, batch managers by 40 percent, and online managers by 20 percent. these responses against the trend of the online manager as more user oriented may be due to the fact that the study was not completely successful in differentiating between responses based on general attitudes and those based directly on the specific system in use. in other words, the relative quality of each circulation system or even the "bugs" peculiar to a ~pecific system may affect one's attitude toward the user's need to tolerate the limitations of that system. manual-system managers know the limitations on their service are keyed to inefficient systems, whereas online-system managers know their systems and services are already at a high level. this knowledge of the system in use colors service attitudes. conclusion the study found a depressed state of circulation-system development and support in arl libraries. seventy-four percent of circulation managers, on average, rated their systems negatively on basic system integrity, as shown in table 2. the thirty manual-system managers gave their systems an average score of 9, to the effect that their systems were ideal, adequate, reliable, and accurate. the twentysix batch managers gave their systems an average score of 10.08, the twenty online managers an average of 13.45. recognizing the considerable constraints under which 194 journal of library automation vol. 14/3 september 1981 today's large academic libraries struggle, there is, nonetheless, room for criticism of library priorities. this study must be viewed as only a first step (largely tentative and exploratory) in relating automation with service attitudes. it suggests that online systems may be associated with managers more positive in their view of the management role and more positive in their attitudes toward users than batchand manual-system managers. further research would be useful at this point to compare levels of automation (manual, batch, and online) with circulation-staff service attitudes or those of patrons using the systems. references l. laurence miller, "changing patterns of circulation services in university libraries" (ph.d. dissertation,

mccallum and james l. godwin: network development office, library of congress, washington, d.c. in designing an automated system, it is important to understand the characteristics of the data that will reside in the system. work is under way in the network development office of the library of congress (lc) that focuses on the design requirements of a nationwide authority file. in support of this work, statistics relating to headings that appear on the bibliographic records in the lc marc ii files were gathered. these statistics provide information on characteristics of headings and on the expected sizes and growth rates of various subsets of authority files. this information will assist in making decisions concerning the contents of authority files for different types of headings and the frequency of update required for the various file subsets. then ational commission on libraries and information science supported this work. use of these statistics to assist in system design is largely system-dependent; however, some general implications are given in the last section of this paper. in general , counts were made of the number of bibliographic records, headings that appear in those records, and distinct headings that appear on the records. the statistics were broken down by year, by type of heading, and by file. in this paper, distinct headings are those left in a file after removal of duplicates. distinctness will not be used to imply that a heading appears only once in a source bibliographic file, although distinct headings may in fact have only a single occurrence. thus, a file of records containing the distinct headings from a set of bibliographic records is equivalent in size to a marc authority file of the headings in those bibliographic records. methodology these statistics were derived from four marc ii bibliographic record files maintained internally at lc: books, serials, maps, and films. the files contain updated versions of all marc records that have been distributed by lc on the books, serials, maps, and films tape:; frum 1969 through october 1979, and a few records that were then in the process of distribution. the files do not contain cip records. a total of l ,336,182 bibliographic records were processed, including 1,134,069 from the books file, 90,174 from the serials file, 60,758 from the maps file, and 51,176 from the films file. a file of special records, called access point (ap) records, was created that contains one record for the contents of each occurrence of the following fields in the bibliographic records:

carol ann information technology and libraries; mar 2000; 19, 1; proquest pg. 29 communications that's my bailiwick: a library-sponsored faculty research web server pau/a.soderdahland carol ann hughes the university of iowa libraries provide a unique, new, scholarly publishing outlet for their faculty and graduate students. with the prevalence of personal faculty home pages and course web sites in just about every department on campus, it's not very hard for faculty to find a web server somewhere for storing an html file. and, with some work, faculty can often find some "techie" to help convert a document to html or to save a list of links. what is rare, however, is a space on the web where faculty from all disciplines can find a home for their scholarly research interests, coupled with a computing environment and a knowledgeable staff to help them "follow their bliss" in digital form. the information arcade's new bailiwick project does just that. the need for something new for a number of years, academic departments in the humanities and social sciences have been able to mount departmental information on the university of iowa's central web server maintained by academic computing. more recently, two centrally administered course web servers have been made available to any faculty member or teaching assistant offering a credit course. based on feedback from faculty and graduate students, however, the university libraries learned that there was no place for a research idea or other academically oriented "pet project" to be published on the web. instead, faculty and students needed to bury these somewhere on a personal home page, often with a commercial internet service provider at their own expense . rising to address this need, the university libraries sought to provide a well-respected, institutionally supported web server for just this sort of electronic publishing endeavor. what originally started as simply a "projects" directory on the library's general web server has now grown into the bailiwick project. officially launched in march 1998, bailiwick provides a space on the web where academic passions can be realized as highly specialized and creative web sites. it is not simply a place for personal home pages, nor is it intended for course web sites or academic departmental information. rather, bailiwick is designed to provide faculty, staff, and graduate students with web space where they can focus on a particular area of scholarly interest. bailiwick is not meant to serve as the new model for scholarly publishing in peer-reviewed journals . most electronic publishing initiatives arise from an attempt to transfer existing models of print publishing to the digital environment. a small number of electronic scholarly journals are currently published on the university of iowa campus, and the university libraries already provide a number of ways to support this medium, from archiving to cataloging to hosting journal sites, as one element of the university libraries' new scholarly digital resources center . bailiwick, instead, provides a web space that allows authors to harness and exploit this new electronic medium, permitting new models of expression with multimedia, hypertext, and the ability to incorporate anything in digital form. it is not intended to substitute or even compete with traditional scholarly publishing or electronic journal publishing. rather, bailiwick provides an opportunity to engage in an entirely new medium for scholarly communication. a history of innovation the heart of the bailiwick project within the library environment is the information arcade, an award-winning facility located in the university of iowa's main library. opened in 1992, the information arcade is a place that provides access to published electronic information resources coupled with state-of-theart multimedia development workstations that allow faculty and students to digitize and manipulate source materials that are not already in electronic form. the facility also houses a fully networked electronic classroom, with twenty-four student workstations, where classes from throughout the university are heldsome for the whole term and others for one or two class sessions. in support of its unique service mission "to facilitate the integration of new technologies into teaching, learning, and research," the information arcade is well regarded as a place for innovation and risktaking on the university of iowa campus . it is a place where ideas can be fleshed out; a place that can respond to the real technology needs presented by faculty and students . when the information arcade first opened, it was the only fully wired electronic classroom on campus, with a workstation at every student's desk. it was the only publicly accessible facility on campus where any faculty member or student paul a. soderdahl (paul-soderdahl@ uiowa.edu) is head of information arcade, and carol ann hughes (carol-hughes@ uiowa .edu) is head of information , research, and instructional services at the university of iowa libraries. communications i soderdahl and hughes 29 reproduced with permission of the copyright owner. further reproduction prohibited without permission. could create digital video on a dropin basis. it was the only computer facility on campus where anyone could access the internet for free. all of these innovations are now mainstays on campus. in 1998 the information arcade expanded its offerings with three new innovative web-based services. the moo project this text-based virtual reality campus for the university of iowa community is made possible through the magic of moo, a piece of software that creates a networked environment on the internet that is part e-mail, part chat-room, and part programming interface. known collectively as "the mediatrix," this educational moo currently houses two distinct academic projects. the scholar's web project, devoted to the possibilities of digital communication in graduate education, makes its moo home in "the cave." the mooniversity project, which strives to provide a virtual undergraduate learning environment that encourages collaboration across campuses and disciplines, is located in "the mooniversity." coadministered by d. diane davis, assistant professor of rhetoric in the rhetoric department, and michael calvin mcgee, a professor of rhetoric in the communications studies department, the mediatrix is available to any faculty member wishing to make use of either of them for teaching and research. the streaming video project with text-based virtual reality at one end of the spectrum, the information arcade simultaneously launched a new streaming video server to meet high-end multimedia needs for delivering real-time motion video and audio over the internet. with a fifty-user license to real networks' real server, the information arcade now provides students and faculty with the ability to serve digital movie files to several locations simultaneously. because of the streaming quality of the video files, users do not need to wait for an entire file to download before playing it. already used by bob boynton, professor of political science, for his multimedia politics class, the streaming video server provides a delivery mechanism for the digital videos created by students and faculty at the information arcade's multimedia development stations. the bailiwick project by linking new modes of communication and providing an outlet for any number of innovative scholarly projects, the bailiwick server has become a home for research projects, complementing the university libraries' course web server. space is available on this research web server to any university of iowa faculty, staff, or graduate student developing a scholarly academic web site or web-based tool that might be experimental in nature. open by simple proposal, bailiwick runs on a dedicated web server within the library and is supported by the university libraries' web server infrastructure. content providers retain editorial control and freedom, and have the ability to define their topic of interest, identify the target audience, and design a customized web site. each bailiwick is initially limited to 5mb of space, with the ability to petition for more based on specific needs for a given project. in addition to disk space, authors can turn to library staff at the information arcade for consultation on site design, graphics and layout, technical support, and training. an individual bailiwick might: • serve as a home page for artistic expression and collabora30 information technology and libraries i march 2000 tion among artists working in iowa and other states; • be a showcase for digitally produced art that incorporates interactivity meant to be viewed on a computer screen; • provide a natural home for hypertext experiments that explore new forms of multilinear argument or open-system documents that welcome, even depend on, links to other web sites to expand or counter those arguments; • host a site not full of bells and whistles, but simply a collection of narrowly focused pages of links to resources on a given topic; and • offer an electronic publishing medium for delivery of specialized bibliographies or digital reproductions of rare documents. there are currently eleven bailiwicks in production, with another eight in development. the authors of bailiwicks represent thirteen different academic departments, including communication studies, political science, athletics administration, and theatre arts. they range in rank from teaching and research assistants to full professors. sample bailiwicks currently, developed bailiwicks fall into one of four categories: (1) a collection of internet links on a specialized topic of study, ranging from a small set of links on a particular page to an annotated internet bibliography of thousands of links; (2) a hypertextual or multimedia essay or thesis that necessitates publishing in this medium; (3) a scholarly research project that is dynamic or updated with such frequency that print publishing would be ineffective, including, for example, ongoing findings from a research study; or (4) a collaborative project that makes use of a reproduced with permission of the copyright

bailiwick shared electronically accessible work space. the internet bibliography karla tonella, a graduate student in mass communication, has authored three different bailiwick sites that loosely fall into the category of internet bibliography. as a former graduate assistant and information arcade staff member, tonella first identified the need for this sort of publishing medium on campus and articulated the concept of the bailiwick project. she was instrumental in bringing the server to fruition and quickly adopted it as a home for two comprehensive and award-winning sites of internet resources in her areas of expertise: "women ' s studies online" and "journalism and mass media ." both of these sites have been given widespread praise in those subject areas and have helped bring attention to the bailiwick project, both on campus and around the country . her "border crossings" site (see figure 1) also relies on internet links as its core content, but it is experimental in design and published in a way that is intended to "encourage the browsing readers to consider the areas of their postmodern world where traditional boundaries are being renegotiated and blurred." the site explores the notion of "border crossings" from a number of different perspectives. "border crossings" has received numerous citations in the mainstream press, including a sidebar in the chronicle of higher education, inclusion in britannica online's catalog of recommended sites, and a feature article in search, a monthly newsletter for advanced graduate students published by northeastern university in boston. the multimedia essay the most popular use for bailiwick thus far has been for publishing multimedia essays. the information arcade itself has been a proponent of the multimedia essay since it first opened in 1992, and most semesterlong courses now held in the information arcade's electronic classroom incorporate some sort of multimedia term paper as part of the course requirements . the information arcade is one of the leaders on campus in the adoption of electronic theses and dissertations, working closely with the graduate college and academic computing on a pilot project this semester. it is not surprising, then, that faculty members and graduate students are turning to bailiwick as a medium for publishing these sorts of materials . michael calvin mcgee , professor of communication studies, has published his essay, "suffix it to say that reality is at issue," as a bailiwick (see figure 2). jennifer lawrence-gentry, a ph.d. candidate also in communication studies, created a comprehensive site on the work of mikhail bakhtin, which is now seen as one of the most complete online resources on bakhtin. patrick muller, a teaching assistant in preventive and community dentistry, developed a bailiwick essay titled, "complexity studies: the fluid multifaceted nature of knowledge." the sites are all very different in design, target audience, and perhaps even scholarly value. nonetheless, bailiwick provides an ideal way for the university of iowa to support this sort of experimental multimedia publishing outside the rubric of a class assignment for a multimedia term paper or a communications i soderdahl and hughes 31

traditional electronic scholarly publishing environment. the scholarly research project aside from the hypertextual and multimedia aspects of publishing on the web, the most unique advantage to the web for publishing scholarly research is the ability to maintain currency on a published project. the most well developed example of this is a bailiwick on gender equity in sports (see figure 3), sponsored by the women's intercollegiate athletics department. the site monitors the current state of affairs of gender equity in intercollegiate and interscholastic sport, and tracks title ix compliance and pending title ix litigation at colleges and universities. this resource has received significant national attention and acts as a research tool in and of itself that is published out of the university of iowa libraries and now available for students and scholars across the country. another example is the dogon bailiwick, published by chris culy, associate professor of linguistics . marcel kervran, a member of the congregation of catholic missionaries know as peres blancs, who lived in the town of bandiagara, mali for about thirty years, compiled this dictionary of the dogon language. the dictionary has more than seven thousand head words. a second expanded edition was published in 1993. partially representing the varieties of dogon spoken in and around bandiagara, the dictionary is being expanded from its earlier hypercard format, and it may soon be ported 32 information technology and libraries i march 2000 into an sgml environment. it is an excellent example of an academic toolthat would be difficult to create and deliver in paper form. the collaborative work space the bailiwick server provides a way for researchers at the university of iowa to work collaboratively and in a public forum with colleagues at other institutions. this collaborative space can be used as a way to gather research data, or to allow others to comm ent on or contribute to the development of a site . barbara bianchi, a graduate student in counselor education and an art therapist, has established a bailiwick for global connections, a set of online art and notes from travel journals. one component of the global connections site, called "russia revisited," includes materials from a number of contributing artists and students in russia, who are jointly working together to create a collaborative artistic travel journal. international collaboration is being tested in another project as well. with grant funding, two scholars-one at the university of iowa and one in germany-are working with university of iowa libraries staff to create a new academic resource consisting of a web-searchable critical edition of the work of ingeborg bachmann. this bailiwick will eventually contain bibliographies , a hypertext archive of materials not yet published in any form relating to bachmann's life, work, and cultural context, and a searchable corpus of commentaries and translations. an advisory group for the proj ect consisting of additional international scholars has already been named to oversee the development of content. as it grows, this bailiwick will result in an unprecedented resource for scholars from many disciplines. it presents a new reproduced with permission of the copyright owner. further reproduction prohibited without permission. last

academic web sites that not only reflect serious study but actually nurture the creation of new, international scholarships. other bailiwick proposals are also candidates for outside funding and can follow this exciting lead. policies regarding bailiwick sites bailiwick sites run the gamut in subject area, nature, and scope. no attempt is made to centrally control the content of someone's site . after all, it is their bailiwick and they have complete editorial freedom . on the other hand, there are certain guidelines in place for establishing a bailiwick to maintain the focus of the project as an innovative research web server . first, the site is not intended to be a space for student class assignments. short-term projects intended to meet course requirements can be accommodated currently on one of the university's centrally administered course web servers. in addition, the site is not meant to be a place to mount a personal home page or even a student's career portfolio . this type of activity can be better accommodated on a student's personal account through academic computing or through a commercial internet service provider. sites that are commercial in nature are refused, as are sites that are completely divorced from the university's mission . content providers need to abide by the university's acceptable use policy, which identifies inappropriate uses of information technology resources on campus, such as hacking, forgery, inserting viruses, viola ting intellectual property rights and software licenses, interfering with others' access to information technology resources, or personal campaigning, lobbying, or commercial activities. these modest restrictions notwithstanding, most proposals for bailiwicks ha ve been approved. inappropriate use of bailiwick web space has not yet been an issue. library resources to support the project the hallmark of the information arcade is its dual strength in providing a facility with state-of-the-art, high-end computing equipment for electronic publishing and multimedia development as well as providing a diverse public services staff who can work closely with faculty and students, often one-on-one, to help them harness the technology and integrate it effectively into their teaching, learning, and research. the facility is staffed with six half-time graduate assistants selected from a variety of academic programs in an attempt to achieve a balance of technologists, information specialists, graphics artists, and instructional designers. the primary benefit of this unique staffing arrangement is that the information arcade is much more than just another computer or library lab. it is a place where faculty and students can find qualified consultants trained in a subject specialty with expertise in almost any area related to technology. with this high-tech and hightouch model, the information arcade is uniquely suited to host a project like bailiwick. within the walls of this facility, the library provides support for every step of development from inception to creation to delivery. with expert consultation, access to equipment, technical support , and web server space, the arcade becomes a communications i soderdahl and hughes 33 reproduced with permission of the copyright owner. further reproduction prohibited without permission. one-stop place for presenting scholarly research. staff support includes consultation in any aspect of the bailiwick project, including design issues, interface development, and training in software. staff members do not provide programming nor do they do any work in researching or assembling sites. each faculty member is assigned an information arcade consultant at the point of submitting a bailiwick application. the consultant serves as a primary contact person for technical support, troubleshooting, basic interface design guidance, and referrals to other staff both in the libraries and on campus. at present, the current level of staffing has been sufficient to accommodate this sort of assistance, which is not unlike the assistance provided to any patron who walks in the door of the information arcade. as a computing facility, the information arcade provides public access to a host of multimedia development workstations for scanning images, slides, and text, and for digitizing video and audio. at these multimedia stations, a large suite of multimedia integration software and web publishing software is made available for public use. staff at the public services desk have a strong background in multimedia development and web design and can provide some one-on-one training on a walk-in basis beyond technical support and troubleshooting. all of these hardware and software resources are available to bailiwick content providers, who can choose to do their development work in the information arcade or at their home or office. finally, since there is a close relationship between the information arcade and the university libraries web site, system administration and web server support is all handled inhouse as well. there are few artificial barriers imposed by the technology, thereby permitting content providers to focus on their creative expression and scholarly work. with only minimal reallocation of existing resources, the university of iowa libraries has been able to launch the bailiwick project and continue to develop it at a modest pace. one of the components most essential for its continued success, however, is the ability to scale up to meet the expected demand over the next several years. technical infrastructure challenges are not overwhelming as yet. an analysis still needs to be made to determine how quickly creators are developing their sites, what the implications are for network delivery of these resources, what reasonable projections there are for disk space, and who is using the resources. perhaps more importantly, though, adequate staffing will always remain a concern. some faculty wish to work more closely with library staff consultants than time allows, and the consultants would certainly find it enriching to be more intimately involved with the development of each bailiwick site. marketing of the bailiwick project has been discrete (to say the least) because of the limited staffing available. however, embedded in the collaboration inherent in bailiwicks is the potential for stronger involvement with faculty in obtaining grant funding to support the development of specific bailiwick sites. a model for research libraries bailiwick is a project that allows the university of iowa libraries, and specifically the information arcade, to focus on the integration of technology, multimedia, and hypertext in the context of scholarship and research. to date, most of the bailiwick sites represent disciplines in the arts, humanities, and social sciences. this matches the overall clientele of the information arcade (given its location in the university of iowa's main library), but it also reflects the fact that these disciplines have been tradi34 information technology and libraries i march 2000 tionally undersupported with respect to technology. nevertheless, individual faculty in these disciplines have integrated some of the most creative applications of the technology in their everyday teaching and research, in part because of the existence of the information arcade and the groundwork laid by the libraries for the past several years. with the information arcade's visibility on campus, and with similar resources and support in the information commons-a sister facility in the hardin library for the health sciences-the university of iowa libraries are well regarded on campus as a leader in information technology, electronic publishing, and new media. thus, faculty and students alike are accustomed to turning to the libraries for innovation in technology and the bailiwick project is a natural fit. bailiwick is now fully integrated as part of a palette of new technology services and scholarly resources included within the libraries' support of teaching, learning, and research at the university of iowa. engelond: a model for faculty-librarian collaboration in the information age scott walter the question of how best to incorporate information literacy instruction into the academic

mcandrew information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.12391 chuck mcandrew (chuck.mcandrew@leblibrary.com) is information technology librarian, lebanon (nh) public libraries. due to increased public awareness of online surveillance, a rise in massive data breaches, and spikes in identity theft, there is a high demand for privacy enhancing services. vpn (virtual private network) services are a proven way to protect online security and privacy. vpn’s effectiveness and ease of use have led to a boom in vpn service providers globally. vpns protect privacy and security by offering an encrypted tunnel from the user’s device to the vpn provider. vpns ensure that no one who is on the same network as the user can learn anything about their traffic except that they are connecting to a vpn. this prevents surveillance of data from any source, including commercial snooping such as your isp trying to monetize your browsing habits by selling your data, malicious snooping such as a fake wifi hotspot in an airport hoping to steal your data, or government-level surveillance that can target political activists and reporters in repressive countries. some people might ask why we need a vpn as https becomes more ubiquitous and provides end to end encryption for your web traffic. https will encrypt the content that goes over the network, but metadata such as the site you are connecting to, how long you are there, and where you go next are all unprotected. additionally, some very important network protocols, such as dns, are unencrypted and anyone can see them. a vpn eliminates all of those issues. however, there are two major problems with current vpn offerings. first, all reliable vpn solutions require a paid subscription. this puts them out of reach of economically vulnerable populations who often have no access to the internet in their homes. in order to access online services, they may rely on public internet connections such as those provided by restaurants, coffee shops, and libraries. using publicly accessible networks without the security benefits of a vpn puts people’s security and privacy at great risk. this risk could be eliminated by providing free access to a high-quality vpn service. the second problem is that using a vpn requires people to place their trust in whatever vpn company they use. some (especially free solutions) have proven not to be worthy of that trust by containing malware or leaking and even outright selling customer data. companies that abuse customer data are taking advantage of vulnerable populations who are unable to afford more expensive solutions or who do not have the knowledge to protect themselves. together, these two problems create a situation where having security and privacy is only available to those who can afford it and have the knowledge to protect themselves. libraries are ideally positioned to help with this situation. libraries work to provide privacy and security to people every day. this can mean teaching classes, making privacy resources available, and even advocating for privacyfriendly laws. mailto:chuck.mcandrew@leblibrary.com https://www.forbes.com/sites/forbestechcouncil/2018/07/10/the-future-of-the-vpn-market/#5b08fd8e2e4d https://research.csiro.au/ng/wp-content/uploads/sites/106/2016/08/paper-1.pdf information technology and libraries june 2020 libraryvpn | mcandrew 2 libraries are also located in almost every community in the united states and enjoy a high level of trust from the public. librarians can be thought of as being a physical vpn. people who come into libraries know that what they read and information that they seek out will be protected by the library. in fact, libraries have helped to get laws protecting the library records of patrons in all 50 states of the usa. people know that when a library offers a service to their community it isn’t because they want to sell their information or show them advertisements. with libraries, our patrons are not the product. libraries also already provide many online services to all members of their community, regardless of financial circumstances. examples include access to online databases, language learning software, and online access to periodicals such as the new york times or consumer reports. many of these services would cost too much for individual patrons to access individually. by pooling their resources, communities are able to make more services available to all of their citizens. to help address the above issues, the lebanon public libraries, in partnership with the westchester (new york) library system, the leap encryption access project (https://leap.se/), and tj lamanna (emerging technology librarian from cherry hill public library and library freedom institute graduate) started the libraryvpn project. this project will allow libraries to offer a vpn to their patrons. patrons will be able to download the libraryvpn application on a device of their choosing and connect to their library’s vpn server from wherever they are. libraryvpn was first conceived a number of years ago, but the real start of the project was when it received an imls national leadership grant (lg-36-19-0071-19) in 2019. this grant was to develop integrations between leap’s existing vpn solution and integrated library systems using sip2 which will allow library patrons to sign in to libraryvpn using their library card. this grant also included development of a windows client (there was already a mac and linux client) and alpha testing at the lebanon public libraries and westchester library system. we are currently working on moving into the testing phase of the software, and planning phase two of this project. phase two of libraryvpn will involve expanding our testing to up to 12 libraries and conducting end-user testing with patrons and library staff. we have submitted an application for imls funding for phase two and are actively looking for libraries that are excited about protecting patron privacy and would like to help us beta test this software. if you work for a library that would be interested in participating, you can reach us via email at libraryvpn@riseup.net or @libraryvpn on twitter. if you would like to help out with this project in another way, we would love to have more help. please reach out. we currently are thinking about three deployment models for libraries in phase two. first would be an on-premises deployment. this would be for larger library systems with their own servers and it staff. libraryvpn is free and open source software and can be deployed by anyone. since it uses sip2 to connect to your ils, it should work with any ils that supports the sip2 protocol. this deployment model has the advantage of not requiring any hosting fees but does require the library system to have staff that can deploy and manage public facing services. drawbacks to this approach would include higher bandwidth use and dealing with abuse complaints. phase 2 testing should give us better data about how much of an issue this will be, but https://leap.se/ mailto:libraryvpn@riseup.net information technology and libraries june 2020 libraryvpn | mcandrew 3 our experience hosting a tor exit node at the lebanon public libraries suggest that it won’t be too bad to deal with. our second deployment model would be cloud hosting. if a library has it staff who can deploy services to the cloud, they could host their own libraryvpn service without needing their own hardware. however, when deploying to the cloud, there will be ongoing costs for running the servers and bandwidth used. figuring out how much bandwidth an average user will consume is part of the data we are hoping to get from our phase 2 testing so we can offer guidelines to libraries who choose to deploy their own libraryvpn service. finally, we are looking at a hosted version of libraryvpn. we anticipate that smaller systems that do not have dedicated servers or it staff will be interested in this option. in this case, there would be ongoing hosting and support costs, but managing the service would not be any more complicated than subscribing to any other service the library hosts for their patrons. libraryvpn is a new project that is pushing library services outside of the library to where the library is. we want to make sure that all of our patrons are protected, not just those with the financial ability and technical know-how to get their own vpn service. as librarians, we understand that privacy and intellectual freedom are joined, and we want to maximize both. as the american library association’s code of ethics says, “we protect each library user's right to privacy and confidentiality.” http://www.ala.org/tools/ethics lib-s-mocs-kmc364-20140601053820 book reviews

of libraries and educational technology held at airlie house, warrenton, virginia, september 28, 1970-0ctober 2, 1970. chicago: american library association, 1971. 347p to see how rapidly the field of library networking and communications has moved in recent times, one need only try to review a conference on the subject some years after it was held. what was fresh, imaginative, innovative, or blue-sky has become accepted or gone beyond; errors in thinking or bad guesses as to the future have been shown up; and the blue sky has been divided into lower stratospheres and outer space for ease of working. under these circumstances one can only review such proceedings as history. the assumptions on which the conference was based were the traditional ones of librarians and information scientists-that access to information should be the right of anyone without regard to geographical or economic position, and that pooling of resources (here by networking operations) is one of the best ways to reach that goal. since 1970 both of these assumptions have been questioned, but at the time of the conference there were no opposing voices. the final conclusions, of course, were based on these assumptions. national systems were recommended, both governmental and private, with the establishment of a public corporation (such as the corporation for public broadcasting) as the central stimulator, coordinator, and regulator, to be served by input from a large number of groups. funding, the attendees decided, should be pluralistic, from public, private, and foundation sources (are there any others?), but with the federal government bearing the largest burden of support. since it is deemed desirable to give the widest chance for all individuals to use these networks, it was recommended that fee-forservice prices should be kept low through subventions of the telecommunications costs by libraries and information centers. and since new techniques and methods need to be learned, both education and research in the field must be strengthened and enlarged. since the basic components of networks of libraries and information centers was conceived as being: 1. bibliographic access to media 2. mediation of user request to information book reviews 245 3. delivery of media to users 4. education traditional questions of bibliographic description, the most useful form of public services (including such things as interviewing requestors, seeking information on the existence of answers, locating the answers physically, providing them, evaluating them and obtaining feedback), as well as the best ways to set up networks were discussed at length. moreover, since new technologies have sometimes been touted as the answer to many of these problems, a whole section on network technology was included. such subjects as telecommunications, cable television, and computers were examined; here most of the recommendations still remain to be carried out. the organization proposed for these networks again plowed old ground. the conferees felt that one should use the tremendous national and disciplinary resources already established (the library of congress, the national library of medicine, the national agricultural library, chemical abstracts, etc.); there should be a coordinating body to minimize duplication of effort and assure across-the-board coverage; the systems must be sold to legislators if public money is to be provided; and more research on the best networking operations is necessary. above all in almost every section of the report and in the preface the then-new national commission on libraries and information science was referred to as the great savior. together with requests for public money, it might be said, this was the thread binding all sections of the conference together. was this conference necessary? could it have brought forth something more useful than the gentle spoof in irwin pizer's poem "hiawatha's network?" it was undoubtedly very inspiring for those at the conferenceall 100 of them-who probably learned more over the cocktail glass and dinner plate than at the formal sessions, and who learned as they grappled with the difficulties of consensus-making. but need the proceedings have been published? is everything ever said at a meeting always worth preserving? how about the concept of ephemera rather than total recall? would not a short summary of the recommendations have sufficed? estelle brodman the free software alternative: freeware, open-source software, and libraries james e. corbly information technology and libraries | september 2014 65 abstract this paper will introduce the reader to the world of freeware and open-source software. following a brief introduction, the author presents an overview of these types of software. next comes a discussion of licensing issues unique to freeware and open-source software, which leads directly to issues of registration. the author then offers several strategies readers can adopt to locate these software packages on the web. the author then addresses questions regarding the use of freeware and open-source software before offering a few closing thoughts. introduction i first recognized the potential savings in time, money, and labor offered to librarians and others by freeware and open-source software while i was head of technical and automated services at st. ambrose university in davenport, iowa. among other responsibilities, i oversaw the cataloging and processing of all new library materials. normally, i created original records on oclc whenever i cataloged. one of the tools i needed to complete this work (particularly with foreign language materials) was an ascii chart to provide instructions for making characters not found in english, such as ß, ¿, and ç. today a search for such symbols is relatively easy (most can be found on any character map), but twenty years ago, it presented more of a challenge. i spent many fruitless hours looking for the implement i needed. after much searching, i discovered the right tool—david lord’s ascii chart. this freeware program featured several tables one for ansi characters, control characters, an ebdic table (extended binary coded decimal interchange code), palette (for colors), and a list of ibm pc characters. the first and last charts were the ones i referred to the most. whenever i needed a special symbol in a windows-based program, the ibm pc chart gave me the formula i needed to make it. any time i was in dos or a dos-based utility (as i was with oclc), i consulted the ansi chart to form a diacritical mark. ascii chart was a great piece of software that saved me many hours of work and helped me formulate accurate documents and records. in another instance, shortly after i assumed my duties as the director of library services at kansas wesleyan university, the time clock that registered the work hours of student workers broke down. it was an ancient machine that demanded frequent repairs. and although it dutifully james e. corbly (james.corbly@gmail.com), from austin, minnesota, has been studying freeware and open-source software for over a decade. mailto:james.corbly@gmail.com information technology and libraries | september 2014 66 printed check-in and check-out hours on time cards, it did not calculate the number of hours worked, nor could it prevent such abuses as students punching in and out for one another. rather than taking the machine to a repair shop, i sought an alternative method of record keeping. i found one a computer program from guia international called picture timeclock1 which not only registers each student’s work hours but also totals them so that monthly summaries of each student’s work record can be compiled with increased speed, ease, and accuracy. the software lists among its features a photo identification module that prohibits one student from signing in or out for another. picture timeclock is freeware, so no monies were involved in its procurement. i then took this process a step farther. each month, i digitized the work record sheets required by the business office so i could employ another freeware program, a pdf editor, to transfer the records from picture timeclock onto the digitized time sheets. together, these two programs reduced the amount of time needed to document student worker hours by 88% while enhancing the correctness of the submitted records. as an added bonus, i obtained a permanent digital copy of each student’s work record which could be readily accessed whenever necessary. today, i still rely on freeware and open-source software to solve many of my workaday problems. i utilize these packages for a variety of purposes including web content mining, manipulating pdf documents, and keeping my computers functioning at their optimal level. what are freeware and open-source software? among the major types of software (commercial, shareware, adware, etc.), freeware and opensource software are unique. freeware is copyrighted software given away by its owner (normally the author) for others to use. the author retains sole possession of the copyright, so users cannot alter the software. freeware authors allow individuals to use their productions in any legal manner but they do not allow anyone to sell the software for a profit. additionally, many freeware suppliers impose boundaries on the use of their products, restricting their application in commercial endeavors, for example. open-source software carries the concept of freeware to its ultimate conclusion. with open source products, the copyright holder gives others the right to study, modify, and distribute the software free of charge to anyone for any purpose. quite often, open source products result from the collaborative efforts of contributors living in numerous locations around the world. raw program code, along with the compiled program, is available to anyone who is willing to obtain it, scrutinize it, and make additions or improvements to it in the expectation that the combined efforts of many people will result in a product increasingly useful and reliable to end users. although some open source products lack documentation, many (if not most) have active user groups or communities which serve as sources of assistance to users. to be considered open source, a software product must meet several criteria, among which are the following: the free software alternative| corbly 67 • the software must be freely available without cost, royalties, or fees of any kind. • the program must be distributed as source code (for programmers) and compiled code (for end users). • end users and programmers may alter the program’s code. • the modified source code must be redistributed under the same conditions as the license for the original version of the software.2 one must guard against the temptation to equate freeware and open-source software with publicdomain software. this latter category of software is not copyrighted; hence, it is free of all costs and can be employed without any restrictions whatsoever.3 freeware and open-source software possess copyrights. although many users may be unfamiliar with the concepts of freeware and open-source software, they nonetheless rely on them every day in their routine tasks. if one uses the web, one needs to use a web browser. those who employ microsoft’s internet explorer are using one of the most popular freeware products available,4 while firefox users rely on an open source package.5 many freeware and open source systems are standards in their fields. ccleaner (freeware) has won numerous awards for its efficiency not only as a cleaner and system optimization tool but also as a guardian of user privacy.6 audacity (open source) is a sound recorder and editor employed not only by amateurs but also by professionals in the field.7 access to the web would be impossible without the use of apache (open source), the number one http server.8 it is also important to note that software can change type. freeware can become shareware, commercial software can morph into freeware, etc. licensing licensing of open source products is rather straightforward. although there are over sixty-five different open source licenses, one predominates the general public license (gpl). this is the most popular license used for open-source software. the gpl serves as the license for approximately 70% of open source products. the gpl first appeared in 1989. richard stallman, formerly of the massachusetts institute of technology and founder of the nonprofit free software foundation, authored it. modifications made to the gpl helped keep it vibrant as the years passed and the information technology world changed. as of this writing, the gpl in use is the third version, which came out on june 29, 2007. the foundation of the gpl consists of four principles: 1. the right of individuals to use software for any purpose; 2. the right of individuals to alter software to meet individual needs; 3. the right of individuals to share software with others; and information technology and libraries | september 2014 68 4. the right of individuals to freely distribute the changes one makes to software.9 to these ends, the gpl gives end users the right to freely reproduce and distribute copies of a software program’s source code, providing that each copy displays a copyright notice, a disclaimer of warranty, a copy of the gpl, and gpl notices. the right to modify the software’s code and freely distribute it to others, taking care to list all modifications made to the code and insuring that every condition outlined above is met. commentators often refer to gpl as “copyleft” licensing. copyleft is a method of making software freely available and requires all modified versions to meet the criteria already listed. one can read the text of this license at: https://www.gnu.org/licenses/gpl-3.0.txt.10 in addition to the gpl, open-source software authors distribute their work under other arrangements such as the berkeley software distribution licenses (bsdl), the mozilla public license, the nasa open source agreement, and the common public license. freeware licensing is not nearly as uniform as open source. there is no freeware equivalent to the gpl and the rights and responsibilities of the copyright owner vary from program to program. having noted this, there are clauses that many freeware licenses hold in common. among these are the following: • the copyright to the software is retained either by the author of the software or its provider. • end users may install the software and use it for any legal purpose. • one may install and use the software only on a specified number of computers. • users may copy and distribute the software provided the original copyright remains intact. • one cannot charge a fee for copies of the freeware save for distribution costs. • the software is provided “as is” the copyright owner assumes no liability for any damage caused by product usage. • freeware frequently has usage limits. many freeware licenses permit only personal or noncommercial use of the product. there may be limits on use of the freeware with other software packages and restrictions on freeware use over a network. with such a variety of clauses such as these, it is hardly surprising that freeware licenses vary in length. one freeware program i regularly use has a license consisting of three small paragraphs, while another boasts a license five pages in length. due to these characteristics of freeware licensing, i always copy the text of a freeware license to a blank page of my word processor. i keep this document in the master file of the software so that it is readily available should it be required for any exigency. https://www.gnu.org/licenses/gpl-3.0.txt the free software alternative| corbly 69 software registration the above section on licensing leads directly to questions regarding registration. in this arena, freeware and open-source software differ from other types of software. when employing freeware and open source products, one often finds differences between “personal” and “business” use. many of these packages allow unlimited use of the software as long as its use is strictly personal. in other words, if one downloads a software program, installs it on one’s computer, and utilizes it strictly for one’s own, non-commercial purposes, then use of the software is free. personal use refers to all usage that does not generate financial income, such as scrap-booking, creating personal websites, personal blogs, and print jobs such as flyers, posters, and t-shirts for grade schools and local food banks. in this case, one would simply register the software in one’s name. additionally, charities and other non-profit institutions (such as public, academic, and school libraries) may ordinarily employ freeware and open-source software under the same precincts as individuals, i.e., as personal users. however, suppose one works at a for-profit enterprise and desires to install the software on his/her office computer. naturally, since the firm owns all its office computers, one usually registers the software in the company’s name. under such conditions, many freeware packages oblige the user to seek permission from the software owner for such use. commercial use may also require a fee from the user to the software owner. these caveats also apply to individuals who obtain this software for engagement in their own moneymaking endeavors (such as freelancing). the end-user license agreement, included with all freeware packages, contains information to guide users in such contingencies. to avoid worrying about these details, some freeware and open source users simply treat these programs as if they were commercial products and register their use accordingly. this is a safe practice to adopt. one may be surprised to learn that numerous freeware and open source packages do not require registration at all; others regard user registration as a voluntary exercise. both stipulations presume non-commercial use of the software. locating freeware and open-source software finding freeware and open-source software is a rather simple process. a good place for the neophyte to start searching for them is at datamation.11 datamation is a periodical that began life in hard copy format in 1957 but morphed into an e-journal in the 1990s (the final print edition appeared in february 1998). to access the list of open source replacements for popular commercial security tools, for example, simply click on the “open source” heading of the menu bar on the home page of the website. scroll down the next page to discover the list of alternatives to information technology and libraries | september 2014 70 commercial security software in such categories as anti-malware, backup, and browsers, until finally, the reader reaches the last category, web filtering. another important resource comes from pcmag.com. each month, the site presents a list of the best free software available in a particular category such as firewalls, video conferencing, antivirus, and presentation software. both freeware and open-source software are included in each category. last year, experts in the field examined over one hundred free software packages from nine categories. most of the evaluated packages operate on either windows 7 or windows 8, although programs designed for other platforms, such as mac os and android, were included in the lists. also assayed are free cloud-based web applications which run in a browser. note that the lists of free software from 2012 and 2013 are readily available.12 john corpuz’s “45 free and useful windows applications” is a slideshow presenting detailed information on useful applications from a variety of software categories. embedded within each software description is a link which, when clicked, takes the reader to a window where that software may be downloaded.13 dottech offers one of the most comprehensive lists of freeware for windows available. this list consists of individual reports organized around nine categories: cleaning and maintenance, communication, files & documents, work & productivity, pdf tools, privacy and security, multimedia, network/internet tools, and miscellaneous. each report is well-written, concise, and features the type of information computer users need. although i disagree on some of the choices labeled as “best,” i cannot but appreciate the exhaustive nature of these documents. since dottech continuously revises and expands the number of reports in this set, wise users make periodical visits to this site.14 a quick search of the web will bring one to the open-source software directory where one will find open source applications listed by broad categories on the left side of the home page, categories which are then separated into topics before being subdivided by function. to discover network management software, for example, find “administrators” (category), then “networking” (topic), and finally, click on “network management” (function). in this manner, one will obtain a list of open source products matching this description.15 techradar provides another register of recommended free software.16 this site provides detailed descriptions of seventy-six freeware packages, ranging from productivity software to games. a link takes users to techradar’s download channel where one may read information on freeware and open-source software categorized by function and specific name.17 one cannot discuss freeware without mentioning the world’s largest supplier of freeware, microsoft. veteran users of its windows operating system and its office suite are undoubtedly cognizant of the templates and other helps the firm offers them. those implements represent merely a sampling of the valuable and diverse tools the company makes available to the computing world. microsoft provides access to their abundance of freeware via a download site on the web;18 the free software alternative| corbly 71 however, many people find the site difficult to navigate. for this reason, many individuals consult a friendlier, third party site that opens the doors to this unique collection of freeware. one of the better examples of these sites can be found at gizmo’s freeware.19 internet download directories offer an easy and convenient avenue for one to obtain freeware and open-source software. there are a plethora of such sites on the web; unfortunately, they are not all of equal value. some sites are simply better than others. here is a brief list of criteria one may employ to judge these sites: • ease of use. is the site easy to navigate? does it feature categories that enable one to search for a specific type of software? if it contains categories, does their organization enable one to find software quickly and efficiently? • language. can one easily comprehend the language used to describe the software? does the language express complex concepts in laypeople’s terms or in a manner targeted to information technology professionals? • are the software packages accurately described? do the descriptions detail desirable and undesirable traits of the software? do they clearly indicate the operating system required by the software? what other prerequisites does the software require for effective operation? are alternatives to that software specified? • are software reviews presented? if so, who wrote the reviews laypeople or information technology professionals? do the reviews offer download statistics? does the site contain a ratings system easily understood by the user? • are aids available to help users make optimum use of the software? if aids are available, what format are they in videos, documentation, other? • look for other features which may prove useful, such as: is there a link to the software’s home page? does the download directory provide access to more than one download site? among the download sites meeting these criteria are the following: cnet download.com http://download.cnet.com/windows/ majorgeeks.com http://www.majorgeeks.com/ softpedia http://www.softpedia.com/ filehorse.com http://www.filehorse.com/ softonic http://en.softonic.com/ filehippo.com http://www.filehippo.com/ freewareweb http://www.freewareweb.com/ http://download.cnet.com/windows/ http://www.majorgeeks.com/ http://www.softpedia.com/ http://www.filehorse.com/ http://en.softonic.com/ http://www.filehippo.com/ http://www.freewareweb.com/ information technology and libraries | september 2014 72 freeware guide http://www.freeware-guide.com/ freeware files http://freewarefiles.com/ sourceforge http://sourceforge.net/ this brief list does not even begin to exhaust the number of internet download directory websites available for use. frequent visits to these and similar websites will prove amply rewarding. another method of finding this software is to simply look for it on the web via a search engine. to do this most efficiently, one will need the proper name of the software one is trying to obtain. however, if one has that element, one will find this an effective technique of obtaining freeware and open-source software. how does one seek freeware and open source equivalents to commercial software and shareware? first, one may consult a website entitled alternativeto.20 this website will present one with a list of alternatives to specifically named commercial software packages. one has only to click on the search dialog box, key in the name of the commercial product one wishes to find alternatives to, and press the search icon. the list of results will include freeware, open-source software, and commercial products. clicking on the name of the product with transport one to that product’s home page, where one will gain additional information on that product and be given an opportunity to download the product onto one’s computer. secondly, one may consult any of several lists of software equivalents from the web. one of the better of these registers is “100 open source apps to replace everyday software,” by cynthia harvey.21 this list provides not only names of individual open source projects and the commercial packages they replace but also links to homepages of these projects. library-specific freeware and open-source software in the past several years, an increasing number of librarians have turned to freeware and opensource software to help them fulfill the duties they are obligated to discharge. one of the most renowned examples of library-specific open-source software is koha, an integrated library system.22 programmers and librarians developed koha fifteen years ago for the horowhenua library trust in new zealand. since then, libraries of all types, including public, academic, and school libraries, have adopted koha as their integrated library system. numerous consortia across the globe also employee koha to meet their needs and those of their users. one way novices may apprise themselves of this software is to consult websites such as the creative librarian, which features a page entitled “open-source software for libraries,” where software is enumerated by library function.23 any type of library, irrespective of the library’s size, can utilize the software described on this page. http://www.freeware-guide.com/ http://freewarefiles.com/ http://sourceforge.net/ the free software alternative| corbly 73 questions regarding the use of freeware and open-source software all this is not to say that freeware and open-source software do not have their challenges. for instance, in one anecdote i related in the introduction in this paper, i did not name the pdf editor i used at kansas wesleyan. that is because the software is no longer available; unfortunately, neither is david lord’s ascii chart. whenever one spots a piece of freeware or open-source software that may be useful, it is imperative to download it immediately. the availability of many packages is limited, and once gone, they are usually difficult, if not impossible, to obtain. another concern regards documentation. when i first obtained picture timeclock, for example, a complete set of instructions was available from the software provider. that is no longer the case. although an increasing number of freeware and open source packages offer documentation, many do not. however, as noted earlier in this report, many open-source software products have user groups called communities that exist not only to improve the software but also to provide technical assistance to those who use the software. downloading freeware and open-source software presents its own quandaries. even though most providers of these packages go to great lengths to insure the cleanliness of their product, it is nevertheless true that viruses and malware sometimes attach themselves to this software. whenever my security software activates during a download, i immediately cease the downloading process and make a note of the site for future reference. additionally, i always run my security software against all software downloads before installing them in order to keep my system free of any potential threats. issues also arise from employing freeware and open-source software in business offices. individuals bring most of this software into enterprise environments. since the organization itself doesn’t procure this software, the corporation’s information technology personnel may be reluctant to provide support. indeed, the corporation’s it department may not even permit an individual to download any outside software whatsoever onto a system under their domain. before one attempts to install such software (regardless of type of software) on one’s business unit, one should check with the company’s it people to obtain their views on the proposed installation. closing thoughts one question remains: why bother with freeware and open-source software? are librarians searching for new software programs to master? do they need an additional task to add to their todo lists? are freeware and open-source software worthy of the attention of already overworked and stressed-out librarians? yes, they are worthy of our attention. why? for three key reasons. first, freeware and open-source software are cost-effective. for no monies whatsoever, freeware and open-source software offer librarians the opportunity to add important new tools to the arsenal of implements at their information technology and libraries | september 2014 74 disposal. that means that badly needed funds can be more strategically used by the library to help enable it to fulfill its mission to its clientele. secondly, freeware and open-source software enable librarians to make increased use of computer hardware. computers are machines: they require software to not only tell them which tasks to execute but also to provide instructions for performing those tasks. with this software, the range of computer capabilities not only expands in terms of numbers but also increases in terms of efficiency. the bottom line: freeware and open-source software enhance the value of computer hardware to the library and its patrons. finally, with the assistance of freeware and open-source software, librarians become better librarians. they manage their time more effectually, make better use of the resources at their disposal, and elevate the degree of customer service at all levels of the organization. freeware and open-source software can expedite the handling of routine assignments and make possible the fulfillment of other jobs that, due to time and human limitations, are difficult, if not impossible, to address. freeware and open-source software are good for librarians, good for the library, and good for those who depend on the library for the fulfillment of their information needs. they truly foster what many individuals refer to as a “win-win situation” in the world of information acquisition, organization, preservation, and retrieval. urls cited 1. “picture timeclock,” guia international corporation, http://workschedules.com/store/product/picture_time_clock.aspx. 2. “the open source definition,” open source

2020, as post-secondary institutions and libraries were adapting to the covid-19 pandemic, libraries and cultural resources at the university of calgary rapidly implemented ex libris’ reading list solution leganto to support the necessary move to online teaching and learning. this article describes the rapid implementation process and changes to our reserve reading list service and policies, reviews the status of the implementation to date and presents key takeaways which will be helpful for other libraries considering implementing an online reading list management system or other systems on a rapid timeline. overall, rapid implementation allowed us to meet our immediate need to support online teaching and learning; however, long term successful adoption of this tool will require additional configuration, engagement, and support. introduction in response to the changes to the post-secondary learning environment due to covid-19 and to better integrate our course reserve reading list services with our library management system (ex libris’ alma), libraries and cultural resources (lcr) at the university of calgary (ucalgary) decided to rapidly implement ex libris’ reading list solution leganto. after rapidly implementing this reading list solution, lcr made it accessible to instructors and students in our learning management system, desire2learn (d2l), for the fall 2020 term. this article will discuss lcr’s decision to rapidly implement leganto, the implementation process, changes to our reserve reading list service and policies, and will conclude by reviewing the implementation so far and present key takeaways. this paper will be helpful for those who are considering implementing an online reading list management system in general but more so for those looking to do so on a rapid timeline. it will also be helpful for those implementing new systems to support changes to services due to covid-19. literature review online reading lists management systems have been in use since the early 2000s. from 1999 to 2000, loughborough university developed and implemented an in-house open-source reading list management system which “was an electronic representation of the academic’s paper-based reading list.”1 since then open-source and commercial solutions have been developed and implemented by many libraries. richard cross summarizes the development and growth of the market for “resource list software” in the uk and notes that “in the absence of a mature commercial market, several uk universities have developed in-house” systems. cross notes that since 2010, commercial solutions have been developed and that “the high-level specifications requirements” for reading list management systems have now been distilled.2 as part of the development of the commercial market, ex libris launched its leganto online reading list solution in 2015; the solution has since been implemented by over 230 institutions worldwide.3 mailto:mblack@ucalgary.ca mailto:spowelso@ucalgary.ca information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 2 overall, the literature on reading list management systems focuses on reviewing implementations and identifying factors that contribute to successful implementation of these solutions.4 also, some literature captures instructor and student perceptions of these systems and provides recommendations for successful engagement and use.5 these recommendations focus on the importance of administrative support for the tool, updating or creating policy and workflows to support implementation, technical configurations and integrations, and faculty/instructor engagement. 6 libraries that have implemented an online reading list system indicate that it is important to have the adoption of the system supported and championed by senior administration within the library and from the wider institution.7 having this support means that reading list policies and services can be aligned with library and institutional goals to support teaching and learning. furthermore, marie o'neill and lara musto contend that successful adoption is dependent on this support and integration with institutional goals and not just “premised on technology.”8 establishing policies and service goals that are supported by senior administration provides an impetus to make sure workflows and functionalities are configured to achieve these. the literature recommends that implementing an online reading list solution provides an important opportunity to review or revise previous workflows or to develop new workflows for standardization and “timely satisfaction of resource list needs.”9 to support these new workflows and services, technical integrations and configurations need to be considered. these include integrations with the library management system, the learning management system (lms), and institutional authentication systems.10 these integrations are essential to make the system streamlined and accessible for instructors and students and are expected by these user groups. for example, when the university of manchester library was implementing leganto in 2019, they surveyed students and instructors and found that students valued convenience and access, and that instructors were interested in a system that would allow them to order books and digitized chapters and see analytics.11 thus, the reading list solution should be configured and implemented with functionalities and integrations to support these expectations. ease of access within the lms is perceived as is an important technical requirement for successful implementation. o’neill and musto’s study finds that faculty had a strong desire to have a reading list system integrated with the lms.12 meredith gorran farkas contends that “positioning the library at the heart of the virtual campus seems as important as positioning the library as the heart of the physical campus.”13 murray and feinberg address the placement of libguides in the learning management system stating it is critical to make resources available despite where students are physically located.”14 this can be extrapolated to reading lists, and in this environment, where students are learning online in geographically dispersed locations, the lists need to be easily available. faculty and student engagement are important nontechnical considerations when embedding library services in the lms. knowing and including relevant stakeholders, gaining instructor buyin and understanding of the benefits, and determining how to raise student awareness of the tool, both short and longer term, are key elements.15 the literature recommends providing instructors with resources such as templates and training “at specific points in the semesters when faculty have less time pressures.”16 however, engagement should not be limited to this: it should be information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 3 ongoing and collaborative. this ongoing engagement can work to create “a virtuous circle” in which instructors “see return on the investment in resource list work” and “improved student satisfaction.”17 one university reports this can provide an opportunity for collaboration and generate “word-of mouth” to promote adoption.18 what is leganto? leganto is a cloud-based reading list solution fully integrated with ex libris’ alma library management system. it allows reading lists to be processed directly in alma by library staff and provides an interface for creating and engaging with readings lists that can be integrated directly into learning management systems using the learning tools interoperability (lti) integration. instructors can use leganto to create reading lists by searching for and adding resources. leganto allows diverse resources to be added to reading lists, including physical and electronic resources that are in alma, ex libris discovery index resources (via their central discovery index), internet sources (any url added manually or through the cite it! browser bookmark tool), or uploaded resources (documents uploaded by the instructor). university of calgary context the university of calgary is a comprehensive research university, ranked one of canada’s top ten research universities.19 the university is home to 14 faculties (offering more than 200 academic programs) and more than 33,000 students are currently enrolled in undergraduate, graduate, and professional degree programs. d2l is the university’s learning management system, managed by the university’s teaching and learning unit. libraries and cultural resources is a principal division of the university of calgary and includes eight libraries on campus and across the city, and two art galleries. the main library is the taylor family digital library (tfdl) which opened in 2011. in 2018, lcr adopted ex libris’ alma as its library management system. pre-covid-19 reserve reading list service prior to covid-19, lcr had distinct and unintegrated systems and processes for managing course reserves and reading lists. while some functions in alma were used to manage physical course reserves, most of the workflows were managed outside of alma. these included a web form that instructors could use to submit requests for course materials and a course reserve tool (atlas systems’ ares product). the submissions from the web form would be reviewed by our copyright office who would determine if the requested item needed copyright clearance or not. through this process, physical items which were already in the library collection were flagged and sent to fulfillment staff. staff would create or update the course in alma, add the item to a course reading list, and move it to a reserve location so it could be borrowed by students. doing this also made the items searchable through our course reserve search in our discovery service (primo). requested items that were not in the library collection were sent to the collections department for purchase consideration. through email communications with the copyright office, instructors could also request parts of items be scanned and approved for use in classes. requests for electronic reserves were not managed in alma. how did covid-19 affect our reserve reading list service? shortly after the covid-19 pandemic became widespread in the province of alberta, the government implemented restrictions which required post-secondary institutions to close physical locations and to restrict or move most courses and services online. in march 2020, lcr had to close all physical locations and was only able to provide online access to resources and information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 4 services. from march to august, lcr focused on online services and promoted access to online resources. the main taylor family digital library was not able to open until august, when we began offering contactless pickup service and limited study space bookings. as of july 2021, the majority of the courses offered by the university continue to be online. as a result, we are not fulfilling instructor requests to make print/physical resources accessible to students through course reserve. this has been a significant change from our previous operations in which physical course reserve was a popular and successful service. in 2019, lcr had a total 3,428 physical items added in alma as course reserve citations and these items circulated 16,345 times. with the announcement that fall 2020 term courses would be predominantly online, and the anticipation that the same would hold true for winter 2021, we realized that a new mechanism to deliver course reserves would be necessary. while we had been considering ex libris’ course reading list tool before the pandemic, the operational changes due to covid-19 provided us with an urgent need and impetus. we had to quickly develop alternative ways to support instructors in creating reading lists and for students to access reading list resources in the online learning environment. leganto rapid implementation leganto implementation is managed by ex libris and is typically done over an eight-to-twelveweek schedule. during this implementation, institutions work with ex libris to set up configurations to meet local needs. in 2020, ex libris began offering rapid implementation for leganto, which involves a shortened timeline of approximately four to five weeks. this is achievable because institutions allow ex libris staff to set up the leganto now configuration, which focuses on configuring essential features to quickly get the tool up and running. there are inherent tradeoffs between the typical and rapid implementation that we needed to consider. the shortened timeline would allow us to launch the service sooner and begin promoting it as a tool to support faculty in moving to teaching online due to covid-19. in addition, because we would implement leganto out of the box we could use the vendor created videos and support tools rather than creating our own. the additional three to seven weeks required for the typical implementation would have provided us more time to fine tune and configure the tool to meet our specific needs but would have delayed our ability to support our faculty in this time of need. for example, the rapid implementation schedule did not include support for setting up workflows for digitization requests or configuration of the more advanced copyright clearance functions to improve automatic processing. to configure these, we would need to work on them on our own while going through the rapid implementation or once the implementation was complete. after considering these tradeoffs, in april 2020 we made the decision to rapidly implement leganto. this decision was supported by the provost and lcr senior administration providing us with the institutional support identified in the literature as necessary for a successful implementation. table 1 outlines the rapid implementation schedule we followed. information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 5 table 1. project implementation schedule event dates kickoff may 27, 2020 implementation may 28 to june 28, 2020 go-live june 29, 2020 switch to support july 15, 2020 the implementation portion involved weekly meetings to review the project status, frequent posting to the online project management tool to update the status and ask clarifying questions, and many internal meetings to discuss our progress and to make decisions about workflows, configurations, and engagement. as a requirement for go-live, at least one reading list had to be created by an instructor and be accessible to students. ex libris offered the opportunity to implement together with the university of manitoba, which is a similarly sized canadian university. this was a great opportunity to not only start implementation sooner but also connect with the university of manitoba. in the short term, rapid implementation would help us meet an immediate need to support online access and learning while operating under covid-19 restrictions. in the long term, this was an opportunity to develop a new way to engage with instructors and further promote our collections as resources for supporting learning. also, it was the opportunity to revise or develop workflows to support these goals. overall, we hoped leganto would make it easier for instructors to add resources to reading lists and to get copyright clearance so these resources would be accessible to students through a standardized tool integrated with d2l. with these goals in mind, we aimed to • pilot leganto for summer 2020 term, • have leganto accessible for all courses by fall 2020 term, and • revise or develop workflows for digitization, copyright clearance, and purchase requests. implementation work despite the out-of-the-box leganto now configuration which aimed to have leganto up and running for our go-live date, implementation still required the lcr team to do a significant amount of work and planning. to manage this work, we established a technical team and an engagement team. the technical team, comprised of representatives from the library’s systems and discovery, copyright, digitization and collections units, the university’s teaching and learning unit, and the associate university librarian, technology, discovery and digital services (aul), worked to review, revise, and develop workflows and to test configurations in alma and leganto. the engagement team, created by a call for participants and comprised of three subject librarians and the aul, worked to develop strategies, communications, and resources to promote and support the use of leganto to instructors. also, the two teams collaborated to test configurations and functions and suggest improvements. the aul’s presence in the teams was critically important to demonstrate senior leadership support of the project, an important element for success noted by o’neill and musto.20 overall, this work required the teams to meet and discuss short-term and long-term changes to our course reserve service and how leganto could be configured to support these. the rapid information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 6 implementation schedule made this challenging because we had to start with the leganto now configurations and then test these to see how they aligned with our desired services and workflows. if they did not align well, we had to investigate and adapt. this was a back-and-forth negotiation as we learned in a short time frame how to configure the system to support our desired workflows and services and how to adjust our services and workflows to align with the capabilities/functionalities of the system. an important part of the implementation was configuring leganto to use the learning tools interoperability (lti) standard to integrate with d2l. as mentioned in the literature, having the online reading list solutions embedded and integrated with the institutional lms is a key factor for successful adoption of the tool by instructors and students.21 using the lti integration, we were able to connect alma, leganto, and d2l. this work required coordination with the adminis trators of d2l at the university so that course and student data could be communicated between d2l, alma, and leganto. after configuring and testing the lti integration, we decided to use it to create reading list (leganto) links in d2l courses through the d2l tools menu. when a user clicks the link, user and course data from d2l is sent to alma to • create the course based on the course information and • assign the appropriate role in alma and leganto for the instructor or student. since lcr could not provide physical reserves because of covid-19, we decided to support the full/partial digitization of physical resources based on copyright approval and the creation of purchase requests for electronic copies of physical items added to a reading list. to achieve these goals, we needed to revise and establish workflows that make use of the basic digitization and purchase request functions in leganto and alma. these functions were not part of the leganto now configuration, but we decided to take the opportunity to make them available to instructors. for our purposes, the digitization workflows and functions in alma and leganto would be used to support the full or partial scanning of physical resources. we already had workflows to support this type of work, but these needed to be revised so requests created by instructors in leganto could be reviewed by the copyright office, items could be retrieved from the collection and scanned by staff, and scans could be made accessible in leganto for instructors and students. the technical team worked with the departments involved in these workflows to determine how the new functions could support this work and how the workflows needed to be adjusted. also, we had to decide how to use the functions in alma and leganto to facilitate electronic purchase requests for print/physical resources added to readings lists. similarly, we already had workflows for this but needed to review and revise these to make use of the functions supported by alma and leganto. using these functions, we configured alma and leganto so that if an instructor added a book to their reading list and we did not have an e-book version, a purchase request for an e-book version would be submitted to the collections department. this was achieved using tags and automatic processing rules with definable parameters. there were a few other settings we had to customize to meet our needs. this included configuring the default out-of-the-box processing and copyright statuses for citations added to reading lists, reading list visibility settings to make sure only enrolled students could access the lists, user interface adjustments to control what functions are available to students and instructors, and interface text/messaging changes to align with our services. information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 7 the other major part of this work involved engagement to publicize the new tool and provide training and support to instructors and library staff. the engagement team worked to develop resources and provided training to staff and instructors. library staff were oriented to the product, the key benefits, and how to add course materials so that they could speak knowledgably to their faculty about the tool. faculty training sessions introduced faculty to the tool and how to add specific types of resources, for example a book chapter, a website, or an item from their personal collection. one libguide was created to support both faculty and staff. ex libris provided support to the engagement team by providing communication templates and advice on engagement strategies. the team also promoted the new tool in our institutional newsletter and worked with the university’s teaching and learning unit to promote it. overall, it was challenging during the five-week rapid implementation to quickly map and adapt our current course reserve workflows and ensure that these configurations will meet long term needs while considering the restraints of the current covid environment. go-live and post go-live we finished implementation on june 29, 2020. for the summer term pilot, we only had one instructor publish a reading list for their course. however, instead of using the functionalities to add citations to the list the instructor uploaded a document version of their reading list. this was similar to what instructors were used to doing in d2l and we had to support the instructor to add the citations from the document to the reading list in leganto. shortly after going live, we had to make the lti link to leganto available in all courses because after publicizing the new tool, we received requests for access from instructors who were preparing for their fall term courses. this was sooner than expected and we believe this was because the online fall term may have motivated instructors to start preparing earlier than usual. with the end of the fall 2020 term, we have been able to use alma and leganto’s analytics reporting to see instructor use and student engagement with reading lists (see table 2). from these reports, we can see that for the fall 2020 term, there were 50 reading lists created that were associated with a course and that had at least one citation added. this means the instructors of these courses at least tried to use the reading list tool. however, of these 50 lists, there were only 30 lists that had student activity. student activity is a category of interactions that ex libris uses to indicate how well the lists are being used by students and includes activities such as reading list views, number of citation views, number of full text views, number of files downloaded, and number of students that have marked a reading as done. we surmise that for the other 20 reading lists, the instructors encountered barriers to list creation and abandoned the process. we continued to use the analytics reporting to monitor the status of instructor use for the winter 2021 term. by the end of that term, there were 66 lists created with at least one citation. information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 8 table 2. fall 2020 and winter 2021 term usage term reading lists with at least one citation added number

has been a valuable and challenging learning experience which has offered several takeaways. go through rapid implementation with another university of a comparable size so that you can connect, support, and learn from each other. rapid implementation is an intense period of uncertainty which can be challenging to go through alone. another institution can provide support and help the implementation team cope. for example, during the implementation we had meetings with the university of manitoba to discuss our progress and challenges with the implementation before meeting with the vendor implementation team. since implementing we have stayed in contact and have been able to rely on each other to discuss the status of our engagement, adoption, and configurations. rapid implementation requires effort and time. the shortened implementation timeline imp lied that it would be relatively easy; however, the project dominated the schedules of those involved and has continued to require work. the weekly meetings with ex libris, the weekly internal meetings, the work in between meetings, and the continuous testing and reworking settings required a significant time commitment from all involved. timing is everything. we had hoped for a successful pilot in the summer term and to use this experience to learn and prepare for the wider rollout in the fall term. however, instructors began preparing for the fall term earlier than expected and consequently we needed to make leganto accessible earlier. understand your instructor timelines and practices around course preparation. the rapid implementation allowed us to respond to this unexpected pressure and begin to support instructors who wanted to make use of the tool. finally, further customizations and integrations will be necessary because of the nature of the rapid implementation and the inherent trade offs. the rapid implementation did not provide the time for us to pursue these customizations and integrations, and this is typical. for example, the course data integration would have required us to coordinate with our central it department and registrar to get approval and resources to build a data source and scripts to export and format the data so it could be loaded by the tool. normal implementation would have provided support and time for this. interestingly, sheedy, wells, and bellenger in discussing their implementation at curtin university noted that they too did not pursue some of the configurations during their implementation.22 regardless of the implementation schedule, libraries maybe uncertain of how these configurations will be useful until after using the tool. information technology and libraries september 2021 a rapid implementation of a reserve reading list solution | black and powelson 9 in our case, it was after implementation that we realized the benefits these configurations could offer staff and users in terms of efficiency. our next steps include • loading course data (we are working on this with our central it department and hope to have it complete for summer 2021), • refining and expanding the advanced automatic rules for copyright approval, • refining digitization workflows, and • implementing the q&a functionality to prompt faculty to describe if they need an entire ebook or just a digitized chapter. these steps will support staff in the administration of courses and reading list in alma and leganto and in improved efficiency in processing citations. furthermore, they will help ensure resources are accessible to all registered students for the appropriate time period. conclusion it is not yet clear if the adoption of the tool has been successful with only 30 lists with student activity for the fall 2020 term and 49 for the winter 2021 term. we had hoped that given the increased need for online learning in this term, instructors would have been eager to use the reading list tool to support student access to resources and learning. conversely, it seems likely that the new tool may have been too much for some instructors during this stressful period.23 sheedy, wells and bellenger noted that there is a potential for system rejection by end users if the change is perceived as creating additional workloads for academic staff, and this may be a factor in our implementation.24 as a result, we will continue to monitor use and determine if our engagement strategies are working. if not, we will need to provide further engagement, training, and support to build interest and use. the public health restrictions due to covid-19 challenged the structure of learning and library services in post-secondary institutions. in some cases, these challenges were opportunities for change. presented with the challenge of how to continue to provide course reserve reading list service, lcr decided to adopt leganto through a rapid implementation. this implementation was an opportunity for lcr to continue to provide reserve reading list service while implementing new workflows to support online access to resources (digitization and purchase requests). although this has met some of lcr’s immediate needs, there is still work that needs to be done to ensure long term successful adoption and use. we will need to continue to review and improve engagement strategies, workflows, and integrations to make the most of this investment. endnotes 1 gary brewerton and jon knight, “from local project to open source: a brief history of the loughborough online reading list system (lorls),” vine 33, no. 4 (2003):

academic initiative using the open-source platform omeka s. drawing on critical, feminist, and open practices, we document the relational labor, dialogue, and tensions involved with this open education project. this case study shares our experience with tools and processes that may be helpful for other small-scale open education initiatives, including user-centered iterative design, copyright education, metadata design, and userinterface development in omeka s. introduction whatcom community college (wcc) is a rural, public institution, located on the lands of coast salish peoples, including lummi, nooksack, semiahmoo, and samish, in the northwest region of washington state and just south of british columbia and the us-canada border. referred to as the pacific northwest or the north puget sound, this area is part of the greater salish sea bioregion (see fig. 1). the sea’s name was adopted in 2009 in washington state and british columbia to refer collectively to the strait of georgia, the strait of juan de fuca, and the puget sound.1 the library at wcc has recently established several new digital services, including the college’s first institutional repository. housed within this repository is a site named the salish sea curriculum repository, which has been developed to host a collection of materials and multidisciplinary curriculum related to engaging college students with this bioregion and is a unique cross-institutional collaboration between the library and the salish sea institute at nearby western washington university (wwu). in this paper, we document, from the perspective of the constraints of a small community college library, the development of the institutional repository service through the creation of the salish sea curriculum repository. this first phase development process began through relational work and proceeded through user-centered iterative design considerations, copyright education, metadata design, and user-centered interface development. a second phase was then launched that produced a curated index of existing work. we document our process to demonstrate a case study of a small-scale, open-source–backed scholarly communication project that can be reasonably replicated by other smaller institutions in order to encourage scholarly communication and open education services at all levels of librarianship. mailto:ingramn@wwu.edu mailto:rmckernan@whatcom.edu https://whatcomdigitalcommons.org/s/salishsea/page/welcome https://whatcomdigitalcommons.org/s/salishsea/page/welcome

teaching and learning 3 ingram-monteiro and mckernan description of library repository service development in spring 2020, our library began to develop an institutional repository in response to a need to document faculty and staff scholarship and student scholarship, including newspapers and journals, and to host a collection of historical college images and videos. lacking the budget for bepress and the dedicated technical expertise to implement dspace, we found that omeka s hosted on a shared server through reclaim hosting was the most appropriate fit for our needs. omeka was originally developed at the roy rosenzweig center for history and new media at george mason university; it offers libraries and museums a way to publish online exhibits while ensuring accessibility and the inclusion of standards-based metadata to support discovery and use.2 omeka s is a later platform that offers one single point of administration for multiple instances of omeka, making it more usable for institutions like ours with a variety of unique collection sites with their own display templates. omeka s adheres to international standards, such as the dublin core schema for metadata, and allows creation of digital content collections, simple web pages, and complex online exhibits. the software can be managed and administered by one librarian. it allows interoperability through the open archives initiative protocol for metadata harvesting (oai-pmh is critical for future ingestion into the digital public library of america, which will provide wider discoverability) and rest apis (which will be necessary for any integration into the library’s opac). as the college’s open education resources and copyright librarian, mckernan initially developed and administers the library’s omeka s installation. while the initial collections were in line with traditional institutional repository sites, a new need developed later in 2020 in response to curricular developments at the college: a repository based around multidisciplinary, land-based learning objects. this repository was the salish sea curriculum repository. development of salish sea curriculum repository relational work, which in our process includes time to build relationships and engage in dialogue, is important given our mutual exploration of open education projects. luo, hostetler, freeman, and stefaniak point to the importance of a campus culture that supports open education, through resource allocation such as oer design and development.3 as part of a larger team, this project represented three institutions (wcc, wwu, and the university of british columbia) with three different open education cultures. and additional faculty partners at wcc and wwu had varying experience with open education, ranging from an awareness of creative commons licenses to experience authoring oer textbooks. dai and carpenter discuss the feminized labor that goes into oer projects, arguing that, like instruction librarianship, oer librarianship is predicated on relational work.4 as feminized work is often invisible and undervalued, they suggest planning and documenting time for consultative tasks such as meeting with faculty as ways of bringing critical, feminist, and open pedagogies into this work.5 by discussing the development of the salish sea curriculum repository in terms of development phases, we want to devote space not just to the final products, but also to documenting this collaborative process. a note on terminology: the eric descriptor place based education is described as pedagogy to engage learners in their cultural, social, and ecological contexts; it often includes inviting community members in as instructors and bringing learners into the natural environments where https://whatcomdigitalcommons.org/s/salishsea/page/welcome https://whatcomdigitalcommons.org/s/salishsea/page/welcome information technology and libraries september 2022 an omeka s repository for placeand land-based teaching and learning 4 ingram-monteiro and mckernan they live. while place-based education is the prevailing term, calderon has argued that the expression of this term has typically erased indigenous relations with land and obscures the violence of settler colonialism.6 in contrast, calderon writes that land education or land-based education makes explicit the ideologies and structures of settler colonialism and that land education centers indigenous peoples’ relations to land, critically examining what it means to inhabit the lands of indigenous nations. we will continue to use the phrase land -based education in this paper. at wcc, the salish sea studies (sali) curriculum was developed by history instructor anna booker in partnership with natalie j. k. baloy of the salish sea institute at wwu. the curriculum includes experiential learning about the complex human-environment systems of the bioregion that builds a sense of place, connection, and relational accountability.7 at both colleges, the instruction teams who co-teach this course rotate from term to term and include faculty from multiple disciplines. instructors at wcc have included faculty from the departments of history, anthropology, geology, and sociology. at wwu, instructors have included faculty with appointments in salish sea studies, canadian-american studies, comparative indigenous studies, the college of the environment, and fairhaven college of interdisciplinary studies. units in the introductory sali course are designed to demonstrate that many ways of knowing are relevant and important to understanding the salish sea. when the second iteration of the course shifted online due to the covid-19 pandemic, with less than two weeks’ notice in spring 2020, instructors shifted to creating learning objects for asynchronous learning. since then, curricula for this course and adjacent courses in salish sea studies have been designed for online, in-person, and hybrid learning. subsequently booker had received a 2020–22 grant from the national endowment for the humanities (neh) to further develop the salish sea studies curriculum. with the pivot to online, she was looking for digital ways to support curriculum sharing. baloy had been approached by ingram-monteiro (who was in the ubc’s master of library and information studies program at the time) about supporting salish sea studies during the initial covid-19 shutdown. baloy connected her with booker about a possible grant work project. because of booker’s previous work on oer with mckernan, she suggested approaching the college’s library about a collaboration. the idea of using existing repository software to build a new site that would serve as a space to collect and share curriculum was born out of this dynamic context. in addition to the rotating instruction team and teaching modality variables introduced by the global health pandemic, the field of salish sea studies as taught in our context was also being defined and articulated concurrent with the initial development of this repository (through distinct curricular conversations). what started as a repository to share open educational resources about the salish sea bioregion became an online space for creating and sharing a curated set of oer explicitly for use in land-based, experiential, multidisciplinary, and transboundary teaching and learning about the salish sea bioregion. phase one: initial digital repository development the first phase of development ran from november 2020 to january 2021. library work in the first phase included designing, building out, styling, and initially populating the repository. we used a user-centered iterative design process in this phase (see fig. 2). user-centered iterative information technology and libraries september 2022 an omeka s repository for placeand land-based teaching and learning 5 ingram-monteiro and mckernan design is used in the human-computer interaction field to foreground user needs during design processes. van house, butler, ogle, and schiff discuss how designers need to know the larger context and purposes of users’ work with a digital library, as well as their specific tasks and information acts, such as searching or repackaging.8 for our project, user-centered iterative design started with consulting faculty partners to help them articulate use cases, identify primary users, and discuss ways to build the repository to incentivize submissions from instructors. these consultations included asking a lot of questions to draw out their needs and wishes for the repository. ingram-monteiro spent about 15 hours (of the 120 dedicated to this phase of the project) meeting or corresponding with our faculty partners over the course of four weeks. our partners contributed this time and more, in addition to their standard workloads and during winter break. this was very much a dialogue, as we went back and forth on some topics over the course of a few weeks, brainstorming together and looking for inspiration to share with each other. figure 2. “agile development” by dave gray is licensed under cc by-nd 2.0. through our dialogue, we were able to articulate that the repository would include adaptable, reusable teaching materials for lessons and courses about the salish sea. users of the repository would primarily include faculty contributors who use the repository to submit teaching materials and instructors from bioregional higher education institutions who use the repository to find material to adapt for their teaching. other users considered could include site visitors who are seeking information about the introduction to salish sea studies course that is taught in parallel at wcc and wwu. copyright education we provided copyright education in various modalities to the instructors who were involved during this phase. our faculty partners’ questions informed how we built copyright considerations into the repository. questions included what materials they could use and remix in a learning object that they would then license for reuse. while they felt protected by fair use for distributing copyrighted videos, maps, or readings within a traditionally mediated classroom environment, this calculus could not be automatically extended for distribution in oer. a recent systematic

libraries september 2022 an omeka s repository for placeand land-based teaching and learning 6 ingram-monteiro and mckernan literature review of empirical oer studies found that faculty are consistently uncertain how to license their creation when it includes remixed materials9 and our experience echoed that.10 the solution for the salish sea repository was the creation of a resources section in the repository that included citations for all rights reserved published works, so that an instructor could point to traditionally copyrighted works without directly uploading them to the repository (see fig. 3). figure 3. screenshot of an omeka s record for an article citation in the resources section. our faculty partners also had questions about creative commons licensing and how to select an appropriate license for their work. we designed the curriculum submission form to include explanations of each creative commons license type, as well as public domain and all rights reserved options. a submitter can read about these six terms and select which license is appropriate for their activity. figure 4. screenshot of copyright guidance and license selector on the submission form. information technology and libraries september 2022 an omeka s repository for placeand land-based teaching and learning 7 ingram-monteiro and mckernan while we were able to provide some guidance in the context of this project, bigger questions remained. faculty partners worked through the challenges of creating public oer from private, contextual lesson plans and learning objects.11 given the curricular emphasis on relational accountability in the salish sea bioregion, and the central role of indigenous knowledge holders and ways of knowing in line with land-based education, materials referenced in salish sea studies include traditional knowledge of indigenous nations. while this knowledge is shared in a consensual way in the context of a course (where a knowledge holder may be an invited guest, for example), sharing these materials in an open repository online introduces different considerations.12 local contexts’ traditional knowledge (tk) labels are a popular topic in open education and have been adopted by the library of congress, but as reijerkerk demonstrates, simply applying these labels in online catalogs is insufficient.13 the use of these labels is intended to be one intervention and done in relationship with indigenous knowledge holders.14 our role may be more to ask questions about existing permissions to share that knowledge, especially around ownership of that knowledge. christen provides more context on how tk labels can be applied in such material when it has been published in the public domain.15 metadata schema omeka s offers linked data infrastructure with the dublin coretm metadata initiative’s dcmi metadata terms (dcterms:) as the default vocabulary.16 we used this vocabulary to create a functional metadata schema that allows faculty to describe their submissions in ways that would be useful for other users. the metadata added during the submission process was then cleaned and enhanced by the librarian who reviewed each submission. for site visitors, this metadata allows browsing through the set of learning objects in the repository; they can browse lessons from a particular discipline or place, for example. they can also perform keyword searching to find results based on titles and lesson descriptions. during this design phase of the metadata, we started with an examination of the types of learning objects that would be shared through the repository. through iterative design we arrived at an initial structure that included four types of objects that would be deposited: assignments, activities, existing published resources, and learning modules. for each type, we then created an omeka s resource template to support consistent metadata processing and a “collecting form” to support metadata collection. we then added 40 resources, one module, two assignments, and five activities—all provided by our faculty partners—to test this structure. after more faculty consultation, we simplified the metadata design to include two learning object types: activities (including assignments) created by instructors and bibliographic citations for core resources used in salish sea studies. we refined our metadata schema for each of these and documented this metadata design and processing. see table 1 for one example. https://localcontexts.org/

interface design once we had a working metadata schema and collection mechanism/workflow and the high -level site structure, we shifted our focus to considerations of the interactivity and look and feel of the repository site. we heard from our faculty partners that they wanted a clean, colorful design that would be appealing to users. they shared the stanford history education group as one example, noting its simple navigation, and blackpast.org, noting its interactive timeline. they also shared spokanehistorical.org, which is built on omeka and includes an interactive map. we tried to manage expectations about what would be possible. we did not have many resources available for web design or experience with the omeka-compatible mapping and timeline tool neatline. still, we found that it was possible to create a simple, visually pleasing interface with some basic css skills, omeka s modules, and documentation from histsex.org, a library collection made with omeka s.17 modules in omeka s are plug-ins that can be installed and activated to add additional functionality. one of the more key modules we activated (on the admin side) was the css editor.18 we could then write an internal style sheet in this editor, in which to style the colors and links in accordance with web content accessibility guidelines for styling headers, color contrast, and text decoration for hyperlinks.19 the css editor module also includes input fields for external style sheets, which enabled us to include one for google fonts. the color scheme we selected uses wcc’s colors and complements the blues and greens of the salish sea. https://sheg.stanford.edu/ https://www.blackpast.org/ https://spokanehistorical.org/ https://neatline.org/ http://histsex.org/ information technology and libraries september 2022 an omeka s repository for placeand land-based teaching and learning 9 ingram-monteiro and mckernan another key module we added was the mapping module.20 this enabled us to represent the spatial coverage of learning objects on maps within the repository. instructors contributing content can associate their contribution with a specific geographic place by placing a marker or entering an address. the librarian processing the contribution can add to and edit this geospatial data. for site visitors, the mapping module allows interactive, map-based browsing of repository items. we initially deployed it only for bibliographic citations because this was the only resource type with a critical mass of existing content when we built the repository. when a visitor opens the resources page from the navigation, they see the option to “find resources by place,” with an embedded openstreetmap that includes markers that link to associated citations in the repository (see fig. 5). the spatial markers help locate scholarship to concepts of land-based education. figure 5. a screenshot of map indicators tied to repository items. a third omeka s module that we installed was fields as tags.21 this module increases the number of browsable metadata fields available to visitors on the main pages of the repository; in addition to title, subject, extent, and creator, visitors can also browse spatial and temporal coverage tags. in the interim months between phase one and phase two, we introduced the repository to wcc faculty who were participating in a year-long professional development workshop about teaching salish sea studies. the culminating project for that workshop involved submitting a teaching activity to the repository. however, while many participants began the submission process, few information technology and libraries september 2022 an omeka s repository for placeand land-based teaching and learning 10 ingram-monteiro and mckernan were able to submit an activity that was repository ready. reflecting on this and their own experiences developing curriculum for introduction to the salish sea, our faculty partners scaled back on expectations for oer development. it was evident that thoughtfully designing land and place-based, experiential, multidisciplinary, transboundary curriculum that is also open and adaptable would require dedicated resources in the context of deeper relationships and a longer timeframe. phase two: a curated index of published works the second phase of development, which took place roughly from july to december 2021, focused on further honing the interface and usability of the site. our faculty partners designated some neh grant funds to pay ingram-monteiro a stipend for summer website development work. further developing the resources section of the repository thus became the focus of our work in summer 2021. by providing a central access point for curated, published works about the salish sea, the repository would support faculty who were developing salish sea teaching materials as oer. we also referred to the resources section as the salish sea index, a space that provides building blocks for teaching materials. developing this index included adding individual pages for maps, collections, and terminology. the maps and collections pages—as well as the original resources page that includes published articles, books, videos, podcasts—are configured to automatically pull in newly entered omeka s items. each item was added using our previously developed bibliographic citation resource template for published resources. whenever there was a creative commons license, open access license, or copyright information provided, we note this at the item level to facilitate reuse and attribution. the digital collections page points visitors to digital collections (such as the northwest indian college salish sea speaker series videos and the south asian american digital archive) as well as to information about physical collections (such as the wing luke museum and the center for pacific northwest studies), which can be visited in person. finally, in addition to maps, journal articles, archival collections, and other media catalogued in the index, another building block for creating salish sea teaching materials is the terminology. this html page is in progress. it will be a reference tool for the vocabulary of salish sea studies, synthesizing concepts that are critical to this multidisciplinary and transboundary pedagogy. providing these building blocks functions as a way of supporting oer creation and remixing. phase three: future work—building transboundary community as of spring 2022, the salish sea repository’s role is to share curricular building blocks, learning outcomes, and sample materials. our faculty partners, with our support, are working on building a transboundary community around the repository, including librarians and interdisciplinary scholars engaged with relational accountability and landand place-based learning in higher education. we are producing this article in this context. as we expressed earlier, we wanted this to document the way relationship building is critical to the development and future growth of this project. as an example, we met with ashley edwards, one of two indigenous initiatives and instruction librarians at simon fraser university (sfu). in her work with the indigenous curriculum resource centre at sfu, edwards collects and organizes http://whatcomdigitalcommons.org/s/salishsea/item/1269 http://whatcomdigitalcommons.org/s/salishsea/item/1269 http://whatcomdigitalcommons.org/s/salishsea/item/1273

libraries september 2022 an omeka s repository for placeand land-based teaching and learning 11 ingram-monteiro and mckernan resources to assist faculty in learning about and engaging in indigenizing their pedagogy and curriculum, centering materials by and about coast salish communities.22 the creation of the center is part of sfu’s response to canada’s truth and reconciliation commission calls to action.23 though no such mandate exists in the us, indigenous and non-indigenous settler faculty at wwu and wcc are engaged with indigenization, as reflected in the inclusion of land-based education in salish sea studies. building a transboundary community invites collaboration with indigenous librarians like edwards, from whose work we can learn how to better support indigenization of curriculum in ethical, responsible, and respectful ways. we also presented the repository at the washington library association academic libraries division/association of college and research libraries of oregon and washington (ald/acrlwa and acrl-wa) academic libraries summit in fall 2021 with the intention of sharing this case study to document our work in the vein of open scholarship. audience questions focused on labor—attendees were interested in knowing about the job titles of people involved with the project. as more oer are developed for sharing in the salish sea repository, we intend to continually evaluate the effectiveness of the repository for users, including user experiences around adapting and remixing the building blocks, filling out the submission form, and browsing learning objects. one area that we expect to focus on is refining the metadata scheme. for example, what is the best approach for describing spatial coverage in this repository, given the variety of place names that can describe one location? we began with a controlled vocabulary and then shifted to an open entry user-defined field. this trades off the user’s ability to browse by a place name for the contributor’s ability to choose the specificity of a location name, which is important given the interdisciplinarity of land-based learning and the inclusion of multiple ways of knowing in this curriculum. we hope metadata librarians will be interested in bringing their skills to this project and working through such questions. future refinements will be driven by these evaluations. summary in response to an emerging, multidisciplinary academic initiative that originated at two local public colleges, our small library utilized our omeka s installation to create the salish sea curriculum repository. we implemented this open education project using a user-centered iterative development process. as of spring 2022, this has involved three phases of development. in the first phase, library work focused on metadata design, copyright education, and user interface development in omeka s. in the second phase, we focused on developing an index of salish sea resources, including information to help instructors find, adapt, and remix published maps, vetted terminology, and bioregional archival collections. the third phase will be focused on building a transboundary community around the creation and sharing of oer that meets salish sea studies learning objectives, including inviting other librarians to bring their specialized skills in support of this project. https://whatcomdigitalcommons.org/s/salishsea/page/welcome https://whatcomdigitalcommons.org/s/salishsea/page/welcome information technology and libraries september 2022 an omeka s

relationships are affected by the way knowledge is accessed and controlled in different contexts. in a 2002 article, rasmus shares several ways that outside researchers unethically extract and disseminate knowledge beyond the community. she shares how knowledge holders will share knowledge without giving it away, but outsiders often interpret this sharing as a license to do with it as they wish. https://cenv.wwu.edu/si/salish-sea-naming-project https://omeka.org/about/project/ https://doi.org/10.1080/02680513.2019.1677222 https://doi.org/10.18278/ijoer.3.1.10

university of alabama, university. this is a summary of a paper written on the consideration of the feasibility as well as the benefits, disadvantages, and consequences of simplification of the marc formats for bibliographic records. 1 the original paper was commissioned in june 1981, by the arl task force on bibliographic control as one facet in exploring the perceived high costs of cataloging and adhering to marc formats in arl libraries. the conclusions and recommendations, however, are entirely those of the author and the opinions and judgments stated here result from a wide-ranging canvas of technical services people, computer people, and/o r library administrators. because the marc format has so many uses, the paper is divided into five perspectives from which the marc format can be viewed: history, standards, and codes; present purposes; library operations; computer operations; and online catalogs. the library of congress has already begun a review of the marc format and has distributed a draft document. 2 the general thrust of that review is a close examination of the marc format in an attempt to begin to lay the foundation on which revised marc formats can firmly standparticularly in regard to content designation (tags, indicators, and subfield codes used to identify and characterize the data explicitly). as that review deals with the very specific, this paper aims generally at attempting to paint with broad strokes a picture of today's marc in its many relationships, benefits, costs, and what the impact would be to the whole from any change to the part. perspective: marc history, standards, and codes relationships the original marc format document established conventions for encoding data for monographs. though it was understood that early applications were going to relate to the production of catalog cards, the marc designers looked ahead to an increasing emphasis on data retrieval applications. other design considerations included, for example, the necessity for providing for complex computer filing, allowance for a variety of data processing equipment, and an attempt to provide for some analytical work (more specific description of contents notes or other types of analysis). later the single marc ii format was transformed into a series of formats, and as time passed, those formats became inextricably tied to other developments at the national and international levels: the international standard bibliographic descriptions, the anglo-american cataloguing rules , 2d ed., unimarc, the national level bibliographic records, and the national and international communications standards; e.g., ansi z39.2-1979 and iso 2709. benefits the benefits of the marc formats and other standards and codes have been substantial both philosophically and pragmatically. the sharing of cataloging records through the computer-based, online networks have been shown in a variety of cost studies to have contained the rate of rise of per unit cost. a further benefit of the marc formats is the momentum its creation gave to the steady movement toward standardization which can benefit individuallibraries in a number of ways: first, bibliographic information can be exchanged among libraries and countries. second, in recent years we have moved steadily toward creating an environment in which the library of congress would become one of many authoritative libraries thus enhancing the shareability of records. costs the early costs of the development and implementation of the marc formats were borne by lc (aided by council on library resources funds). lc continues to bear most of the costs of marc formats, such as new marbi proposals, duplication and distribution of documentation, and so forth. direct investment of library dollars came through the purchase of the marc tapes and the development of systems to receive, process, and output data in marc formats. impact of change throughout the years of its use, the marc format content designation and content rules have been augmented or modified. in the beginning, however, databases were small and changes could be absorbed more readily. the number and complexity of the formats have increased, as have the interrelationships of the marc formats with other standards and codes resulting in a present environment in which the impact of change is felt more strenuously. perspective: present relationships and constraints relationships today's close interrelationships between the marc formats and other codes and standards affect both library and computer operations. though, for example, the general international standard bibliographic description was implemented by the library community prior to the adoption of aacr2, the second edition of the rules has firmly incorporated the isbds. when this format description system is combined with the machine-based marc formats, some isbd information will be supplied by humans and some generated by programmed machine manipulations. communications 287 as a second example, in the last couple of years, the library of congress has spearheaded the development of national level bibliographic record(s) which define the specific data elements that should be included by any organization creating cataloging records which may also be shared with other organizations or be acceptable for contribution to a national database. as the logical idea of a national database comes to fruition, it is necessary for the marc format to provide for greater specificity in the coding of originating library, modifying library, and so forth. benefits the benefits of the use of the marc format continue to lie in the ease with which bibliographic information can be shared and the concomitant beneficial impact on cost control. in addition, the marc format supports a host of other standards and codes and the benefit from these relationships has been consistency in and fostering of standards development. in the bibliographic arena, the more that standards are developed-locally, regionally, nationally, and internationally-the more we will be able to transmit and share bibliographic data, thus controlling the costs of original cataloging. on the other hand, we also "pay" when we standardize. cost the two costs associated with increased standardization are additional time and thus cost required to meet standards, and the increased expense of maintaining local practices which may often be idiosyncratic. in relation to the latter, while many local idiosyncrasies are often unnecessary and counterproductive, there are generally some which have become an integral part of a large catalog database or upon which a major procedural activity is based. but, to benefit from compliance with standards, increasingly we will move away from local practices. in terms of the time required to adhere to the marc format, it is possible to continue to utilize the format (or participate in systems that use it) and yet control the amount of complexity with which one has to deal. both aacr2 and national level biblio288 journal of library automation vol. 14/4 december 1981 graphic record documents allow for "levels of description" which provide for more or less description; and various online networks allow, in a similar manner, for limited input standards. as we view the array of standards and codes which together make up today's bibliographic scene, we can see that each of the separate elements is consistent within itself, is understandable, and counts for only a portion of the costs associated with the cataloging process. the combination of elements, however, begins an accretion of complexity that for most requires an effort of organization and education in order to control work flow and meet standards. impact of change because the marc format is closely interwoven with a number of national and international codes and standards, changes to the format would have implications far beyond the local library. at the very least, discussions would have to involve a host of individuals and groups, all at different stages of development and implementation based upon the present marc format. perspective: library operations relationships in the library-operations perspective, any operations related to the marc format have to be viewed as only one of many elements which must be interfaced with daily work flow. let us look, for example, at the amount of time which might be expended in a typical large academic library by cataloging personnel in training and ongoing work activities required in marc-related operations. in those libraries which obtain access to cataloging databases as members of networks, contact with the marc format is filtered through the standards, requirements , marc implementation design, documentation and other related training facilities of the network. libraries which maintain their own databases do the same kind of filtering, though staff may have somewhat more control of the user cordiality of the interface. the shared networking environment , however, generally seems to imply more standards and requirements because of the attempt to guarantee as much "shareability" as possible. libraries participating in oclc, for example, must train staff in the following codes: aacri; aacr2; standard subject heading codes; standard classification codes; oclc/marc formats for each type of material being cataloged; oclc bibliographic input standards; oclc level i and level k input standards; oclc systems users guides; in some instances, input standards documents for regional or special-interest cooperatives; local library interpretations, procedures, and standards. any close review of the time library staff expend in the use of these tools for either training or ongoing operations reveals that marc per se requires only a limited proportion of a typical library staff person's day. while training may be intensive at either the beginning of a person's job or at the beginning of work with a new type/format of material, this portion of the cataloging unit cost is small. benefits, costs in the cataloging activity, the benefits from the use of the marc formats are at least two: first, the marc format as part of an online cataloging system permits the machine-production of catalog cards at a major savings over manual production. second, access to a shared cataloging database permits the use of "clerical" catalogers at an estimated unit cost saving per book of twenty dollars when compared to "original" cataloging.3 third, depending upon the information available in the cataloging record, the time required for decision making during the cataloging process can be decreased significantly. impact of change it was the general consensus of the technical services people i contacted that simplification of the formats through the consistent assignment of tags would make training and introduction to new formats somewhat easier, but that any savings of time would probably be trivial. there was no consensus that either simplification or shortening would result in any significant time or cost savings. to a certain extent, the use of the very specific marc formats has made the descriptive cataloging process (and the training to undertake it) clearer in that the logical relationships and description of the data elements are so clearly exposed through the assignment of tags and other codes. also, once initial familiarity with the format(s) is achieved, ongoing use becomes second nature. it is also possible for cataloging staff to control the complexity with which they will deal through the use of less than "full," but still nationally acceptable levels of cataloging and, hence, marc coding. finally, most technical services people believe that cataloging and maintenance activities in libraries have always been complex, requiring long and detailed procedures and intricate work flow . while membership in networks requires new skills and knowledge, it is the sum of the whole rather than the difficulty of any single portion which affects unit costs today. changing the marc format through either simplification or shortening would have only a slight effect on the total technical services operation and costs. perspective: the computer operations environment relationships in looking at computer operations, there are at least two major subdivisions: operations that serve only one client (e.g., alibrary system serving itself) or operations that serve many clients (e.g., rlin or blackwell/north america). the constraints differ for each operation and are further complicated by whether or not the computer operation must be able to produce as well as accept bibliographic records in a marc format. each computer facility, for example, can have distinct operating software depending upon the type and mix of computing equipment used. in addition, each computing facility translates the marc-formatted records into an internal processing format which may differ extensively from marc. too, further tailoring may be done for batch processing as opposed to online operations and computer operations which serve a single user may not have to re-create records in the marc format and may even communications 289 more radically redesign the marcformatted records for internal use. as changes to the marc format occur over the years, each computer system will write additional software to incorporate those changes into the then existing system. in some instances, it may be too difficult to attempt to convert old databases to reflect changes in marc coding, and there will then exist an "old" database and a "new" database for that particular marc field or subfield. since changes have occurred in many fields, most databases are an amalgam of new and old interpretations (this is true in relation to cataloging codes, too) of marc coding, and original internal software design may reflect the same type of patchwork quilt. operating these computer systems is complicated, in addition, by the fact that a wide range of user library needs and desires must be accommodated. indeed, a report prepared by hank epstein for the conference to explore machine-readable bibliographic interchange (cembi) revealed after an exhaustive review of the use of marc data elements that there was no data element not used by someone!• benefits benefits that accrue to computing operations as a result of the marc format include the use of what was called "a pretty decent general communications format ," which facilitates communications, card/ com production, and online information retrieval. as a communications format it is as coherent as any other structure for carrying bibliographic data. because the format allows for a very specific level of detail in description, computing operations can supply a variety of products to fill a variety of needs. costs while specific cost information was not available for inclusion in this paper, discussion does reveal some widely held generalizations. first, the marc format does not seem to be any more complex or costly to use than other variable field communications formats. beginning programmers are generally introduced first to the internal communications format of their particular 290 journal of library automation vol. 14/4 december 1981 computing system, and when they come to the marc tags rapidly become familiar with the coding through experience. indeed, if the programmers know the structure of and have a specification for the format, they can work with that format even though they may be unfamiliar with it from the users' point of view. thus, the format itself, and training in its use does not seem to be significantly costly. second, every change in the marc format requires some programming effort and may or may not require concomitant changes in the database. the consensus of the computer people with which i spoke was that the sophistication and specificity of the marc formats was a good thing, but the inconsistencies among formats is problematical. the benefits of consistency can be important, but to justify changes financially, the major changes should be done at one time. indeed, most individuals doubted whether or not there was sufficient capital in these straitened times to be able to implement consistently a major marc format changeand this is from the perspective of both the operations serving one and many users. impact of change without a philosophical and practical framework (or benchmark) against which to compare the benefits and costs of alternative solutions to marc format maintenance issues and without a better and more comprehensive description of the requirements of the internal processing formats of the computer operations, it is difficult to assess clearly the costs and benefits of marc format changes. it does seem to be the case presently that, once established, computer operations can deal with the complexity and specificity of the marc format without undue ongoing financial investment. the strength of the marc format for computer operations lies in its specificity. for the batch processing environment especially, the marc format is a reasonably efficient format and one that facilitates development. its inefficiencies are not drastic and its specificity buys valuable flexibility. severe cuts or major simplifications would be a mistake since discontinuing specificity is a one-way street-once it is gone, it cannot be retrieved. the ability of the machine to assist in editing is weakened by the loss of specificity and it then becomes more difficult to edit out poor data. simplification through consistency, rather than shortening, would produce the most beneficial impact-though it must be done carefully to be cost beneficial. perspective: online catalogs relationship the major difficulties facing us when we attempt to discuss the relationship of the marc format to online catalogs is that, first, we know so little about how people think when they use our card catalogs; and, second, we have so little experience with how those thought and use patterns might change when the online catalog replaces the card catalog. another aspect of online library system development is the combination of subsystems such as acquisitions, serials control, or authority control with the online catalog and the implications of such a combination for system design, the internal processing format, and compatibility with the marc format. the index design of most large online catalogs or information retrieval systems today relies upon precoordinated search keys in order to facilitate the large sorting activities that have to occur. the second indicator in the 700 field, for example, is designed for the purpose of formulating search keys, filing added entries or for selecting alternative secondary added entries. this type of specificity is necessary for both card production and online retrieval. taken together, all of these considerations make most systems and library technical people hesitate to recommend any major changes to the marc format at this time. benefits at this time, therefore, in terms of information retrieval, there does not seem to be any major force toward either simplifying or shortening the marc format to facilitate retrieval. this becomes an even more cogent sentiment when we consider that major development efforts have already been begun in the areas of online catalog access and information retrieval. delays in these development efforts now caused by ........ changes in the marc formats could be enormously wasteful of the time and effort already invested, and could postpone urgently needed implementation of new, easily maintainable online systems. costs there is no firm cost data to guide us in considering the impact of marc format changes in the information retrieval environment. generally accepted assumptions are, however, that because of our lack of knowledge and experience in this area, it is simply too risky and potentially costly to experiment. impact of change overall, without more experience in this area, it is the general opinion that the fullest level of descriptive specificity of the marc format might be required to design and implement online catalogs/information retrieval systems which can be responsive to the needs of a variety of users and levels of information. interaction with other subsystems and formats is also incomplete, thus clouding our vision of the impact of change over the breadth of the library community. summary and conclusions the original purpose of the marc format is still a cogent and necessary one-that of allowing for a great variety of individual library needs for products, practices, and policies via a standardizing communications format. both catalog card production and online retrieval necessitate the same level of specificity, though particular tags, indicators, and subfield codes may vary. as we look toward a variety of authoritative cataloging sources the marc format, in addition to a specific coding of bibliographic information, might also have to specify descriptions of cataloging actions so that the greatest degree of "shareability" might exist. some of this related authoritytype information will either be carried as part of the marc format or in some manner as linked records. the computer operations that utilize the marc formats exist under the constraints of a variety of internal processing formats and design constraints. for each internal processing system, however, the specificity of the marc format offers flexibility and communications 291 efficiency for a number of different processes and products. taken by itself, the marc format is no more difficult to work with than any other standard or technique for both librarians and computer people. while it might be useful for librarians to implement training aids such as online documentation, access to library manuals (particularly that of the library of congress), and so forth, the benefits of aids such as these are trivial since the coding can be learned rather quickly through experience. for computing people, on the other hand, changes in the formats can be very expensive and disruptive. there is general agreement, moreover, that over the long term we have got to be able to maintain the marc format in response to experience with retrieval and other theoretical and technical advances. the main thrust of maintenance in the computing realm is consistency across formats, but approaching this type of simplification requires a number of preliminary steps if it is to be implemented effectively. we need to develop a vocabulary for jointly discussing the elements of the problem. in addition, a major review needs to be undertaken of the internal processing formats and design constraints of the major computer operations-both to serve as a benchmark for measuring the impact of format changes, and as a guideline for newly developing systems to assist in avoiding mistakes in the development of new computer operations. someone needs to be thinking about and designing the ultimate, comprehensive marc format-not to be implemented, but to serve as a springboard for discussion and for consideration of system design. we need to establish limitations on what we will handle with the marc formats and where we will begin to rely on underlying formats instead. the development of a comprehensive marc conceptualization would also provide a protocol for undertaking the improvement of marc and would serve as a benchmark against which local systems could be compared. at the very least, the steps described here would facilitate the consideration and implementation of making the formats consistent across types of material a goal which is seen by all to be highly desirable. 292 journal of library automation vol. 14/4 december 1981 we need a format which is consistent, easily maintainable without being uncontrollably disruptive, and responsive to changing needs which are likely to accelerate as we gain experience with online systems. rather than recommending or supporting the implementation of specific changes to the marc format, it is essential that the library community begin to establish the framework and benchmarks necessary to maintain the marc formats over the long term as well as to guide short-term considerations. arl and others can play an important role in undertaking and encouraging a broader approach to this pressing problem. such an approach will not only reduce the risk of decision making, but will also assist in the development of the cost/benefit data needed to enhance consideration of format changes. references 1. d. kaye capen, simplification of the marc format: feasibility, benefits, disadvantages, consequences (washington,

"average" time reported for searching in card catalogs was 37.3 mindecember_ital_oud_final accessibility of vendor-created database tutorials for people with disabilities joanne oud information technology and libraries | december 2016 7 abstract many video, screencast, webinar, or interactive tutorials are created and provided by vendors for use by libraries to instruct users in database searching. this study investigates whether these vendorcreated database tutorials are accessible for people with disabilities to see whether librarians can use these tutorials instead of creating them in-house. findings on accessibility were mixed. positive accessibility features and common accessibility problems are described, with recommendations on how to maximize accessibility. introduction online videos, screencasts, and other multimedia tutorials are commonly used for instruction in academic libraries. these online learning objects are time consuming to create in-house and require a commitment to maintain and revise when database interfaces change. many database vendors provide screencasts or online videos on how to use their databases. should libraries use these vendor-provided instructional tools rather than spend the time and effort to create their own? many already do: a study shows that 17.7 percent of academic libraries link to tutorials created by third parties, mainly by vendors or other libraries.1 when deciding whether to use vendor-created tutorials, one consideration is whether the tutorials meet accessibility requirements for people with disabilities. the importance of accessibility for online tutorials has been increasingly recognized and outlined in recent library literature.2 people with disabilities make up one of the largest minority groups in the united states and canada, and studies show that about 9 percent of university or college students have a disability.3 problems with web accessibility have been well documented. people with disabilities are often unable to access the same online sites and resources as others, creating a digital divide.4 even if people with disabilities can access a site, it is more difficult for many to use it.5 assistive technologies, like screen-reading software, enable access but add an extra layer of complexity in interacting with the site, and blind or low-vision users can’t always rely on visual cues to navigate and interpret sites. a recent study of library website accessibility concluded that typical library websites are not designed with people with disabilities in mind.6 joanne oud (joud@wlu.ca) is instructional technology librarian and instruction coordinator, wilfrid laurier university, ontario, canada. accessibility of vendor-created database tutorials for people with disabilities | oud https://doi.org/10.6017/ital.v35i4.9469 8 libraries, which are founded on a philosophy of equal access to information, should be concerned about online accessibility. legal requirements for providing accessible online web content vary, but exist in every jurisdiction in the united states and canada. apart from the legal requirements, recent literature points out that equitable access to information for people with disabilities is a matter of human rights and an issue of diversity and social justice, and calls on libraries and librarians to improve their commitment to online accessibility.7 it is important for libraries to participate in creating level playing field and to avoid creating conditions that make people feel unequal or prevent them from equitable access. it is unclear whether librarians can assume vendor-created instructional tutorials are accessible. studies on vendor database accessibility have been mixed, showing some commitment to and improvements in accessibility on one hand, but sometimes substantial gaps in accessibility on the other.8 the focus until now has been exclusively on the accessibility of database interfaces. this study investigates the accessibility of online tutorials, including videos, screencasts, interactive multimedia, and archived webinars created by database and journal vendors and offered as instructional materials to librarians and patrons, to determine whether they are a viable alternative to making in-house training materials. literature review although a few articles exist on how to make video tutorials accessible,9 no studies have evaluated the accessibility of already-created video or screencast tutorials. there are, however, some studies evaluating the accessibility of vendor databases. byerley, chambers, and thohira surveyed vendors in 2007 and found that most felt they had integrated accessibility standards into their search interfaces, and nearly all tested for accessibility to some degree, though not always with actual users.10 these findings conflict somewhat with the results of other studies. tatomir and durrance evaluated the accessibility of thirty-two databases with a checklist and found that although many did contain accessibility features, 72 percent were marginally accessible or inaccessible.11 similarly, dermody and majekodunmi found that students with print-related disabilities who use screen-reading software could only complete 55 percent of tasks successfully because of accessibility barriers and usability challenges.12 delancey surveyed vendors and examined vpats, or product accessibility claims, and found that vendors felt they were compliant with 64 percent of us section 508 items.13 especially relevant to this study, only 23 percent of vendors said that the multimedia content within their products was compliant, and 46 percent admitted multimedia content was not compliant at all. since vendor vpat forms are completed for databases and other products only, and not the instructional tutorials created by vendors on how to use those products, vendor accessibility claims for instructional tutorials are unknown. although no studies have been done on the accessibility of video or screencast tutorials, some have been done on the accessibility of multimedia or other related kinds of online learning. information technology and libraries | december 2016 9 roberts, crittenden, and crittenden surveyed 2,366 students taking online courses at several us universities. a total of 9.3 percent of those students reported that they had a disability, and of those, 46 percent said their disability affected their ability to succeed in their online course, although most reasons cited were not related to technical accessibility barriers.14 kumar and owston studied students with disabilities using online learning units that contained videos. all students in the study reported at least one barrier to completing the learning units.15 although this study involves student use of video tutorials, it doesn’t report on accessibility issues specific to those tutorials. previous studies of vendor products focus exclusively on database interfaces, and previous studies of online learning have not focused on screencast accessibility. therefore this study’s goal is to investigate how accessible vendor-created video tutorials are. accessibility is defined as both technical accessibility (can people with disabilities locate, access, and use them) and usability (how easy it is for people with disabilities to use them). this study will look at which major accessibility issues there are (if any) and make recommendations on whether librarians can direct students to them rather than making in-house instructional videos. method an evaluation checklist (see appendix 2) was developed for this study using criteria drawn from the web content accessibility guidelines (wcag) 2.0. wcag 2.0 is the most widely recognized web-accessibility standard internationally. much recent accessibility legislation adopts it, including the in-process revisions to section 508 guidelines in the united states.16 wcag 2.0 is also consistent with tutorial accessibility best-practice advice found in recent articles, which emphasize the need for accurate captions, keyboard accessibility, descriptive narration, and alternate versions for embedded objects, among other criteria.17 the checklist has twenty items and is split into two sections, “functionality” and “usability.” functionality items test whether the tutorial can be used by people using screen-reading software or a keyboard only, and include whether the tutorial is findable on the page and playable, whether player controls and interactive content can be operated by keyboard, whether captions are available, and whether audio narration is descriptive enough so someone who can’t see the video can understand what is happening. usability items test how easy the tutorial is to use. examples include clear visuals and audio, use of visual cues to focus the viewer’s attention, and short and logically focused content. to help prioritize the importance of checklist items, the local accessible learning centre (alc), which supports students on campus who use assistive technologies, was consulted about the difficulties most encountered by students. the alc’s highest priority was the provision of an alternate accessible version of a tutorial, since it is difficult to make complex embedded web content accessible for everyone under every circumstance and an alternate version allows people to work with content in a way that suits their needs. accessibility of vendor-created database tutorials for people with disabilities | oud https://doi.org/10.6017/ital.v35i4.9469 10 for the evaluation, major database vendors were chosen through a scan of common vendors and platforms at universities, with input from collections colleagues. some vendors were eliminated because they don’t provide instructional tutorials on their websites. twenty-five vendors were included in the study (see appendix 1). a large majority of the tutorials found were screencast or video tutorials; a few vendors provided recorded webinars, and a few provided interactive multimedia tutorials, mainly text captions or visuals with clickable areas or quizzes. in total, 460 tutorials were evaluated for accessibility: 417 video, screencast, or interactive tutorials from twenty-foure vendors, and 41 recorded webinars from four vendors. if tutorials were available in more than one place, most commonly on both the vendor’s website and youtube, both locations were tested. if more than thirty tutorials were provided by a vendor, every other one was tested. if multiple formats of tutorial were available, such as screencasts and recorded webinars, each format was tested. testing from the perspective of people with visual impairments was a key focus. other assistive technologies such as kurzweil (for people who can see but have print-related disabilities) and zoomtext (for enlargement) are widely used, but if webpages work well using screen-reading software intended for people with visual impairments, they also generally work using other kinds of assistive software. tutorials were tested with two screen-reading programs used by people with visual impairments: nvda (with firefox), a free open source program, and jaws (with internet explorer), a widely used commercial product. both were used to determine whether any difficulties were due to the quirks of a particular software product or a result of inherent accessibility problems. in addition, captions were evaluated to determine accessibility for people who are deaf or have hearing difficulties. people with visual or some physical impairments use the keyboard only, so all tutorials were tested without a mouse using solely the keyboard. during testing, each task was tried three different ways within nvda or jaws before deciding that it couldn’t be completed. if one of the three methods worked the task was marked as successfully completed. if a task could be completed successfully in one screen-reading program but not the other, it was marked as unsuccessful. screen-reader support needs to be consistent across platforms, since people may be using a variety of types of assistive software. findings and discussion tutorials created by the same vendor nearly all used the same approach and had the same checklist results. this is positive, since consistency is important for accessibility and helps in navigation and ease of use. none of the forty-one recorded webinars tested in this study were accessible. webinars did not have player controls that were findable on the page by screen-reading software or usable by information technology and libraries | december 2016 11 keyboard. none had captions, transcripts, or alternate accessible versions. often webinars were quite long, with no clear structure and no cues to focus attention on the screen. recorded webinars had almost no accessibility features and can’t be recommended for use as accessible instructional materials in their current form. none of the screencast or video tutorials tested were completely accessible, and all failed in at least one checklist item. tutorials from some vendors, however, came close to meeting all checklist requirements. overall, there were many positive accessibility features in the video and screencast tutorials. most of these tutorials were findable and playable by screen reading software in some way, had video player controls usable by keyboard, had descriptive narration so people who can’t see the screen can tell what is happening, had clear visuals and audio narration, used simple language, and were relatively short and focused in content. the most accessible screencast or video tutorials were produced by the american psychological association (apa), american theological library association (atla), modern language association (mla), and ebsco. their tutorials had many accessibility features and rated highly on the checklist. they included much less commonly found accessibility features, especially the use of visual and/or audio cues to focus the viewer’s attention and the inclusion of accurate and properly synchronized closed captions. visual cues are important for people with learning or attentionrelated disabilities, and help all viewers interpret and follow the video more easily. people who are deaf can’t access the content without captions, and captions also help people who have english as a second language or are at public computers without headphones. tutorials from these vendors also had an alternate version or transcript available. as mentioned earlier, the highest-priority checklist item is the presence of an alternate accessible version, since it is difficult to design multimedia that works for people with all disabilities in all circumstances. people with disabilities may also have previous negative experiences with online multimedia and prefer to use an alternate format that they have had more success with. in the case of these above-average vendors, the alternate accessible version was a transcript consisting of the video’s closed captions, auto-generated by youtube. since the tutorials’ narration was descriptive and the captions were accurate, the auto-generated transcripts are useful. however, the youtube transcript is hard to find on the youtube page. also, most of these vendors had tutorials available both from their own websites and from youtube, and none had alternate versions available on their own websites. viewers requiring an alternate format would need to know to go to the youtube site instead of the vendor site to find it. two other vendors also had quite accessible tutorials. ieee’s tutorials had the same positive accessibility features already mentioned. tutorials were done in-house and presented through the vendor’s site. while most tutorials presented on vendor sites were lacking in accessibility, ieee’s were well thought out from an accessibility perspective and usable by screen-reading software. these were the only tutorials tested where all interactivity, including pop-up screens, was easily accessibility of vendor-created database tutorials for people with disabilities | oud https://doi.org/10.6017/ital.v35i4.9469 12 usable and navigable by keyboard. the one accessibility issue was the lack of an alternate accessible version. elsevier’s sciencedirect tutorials took a different approach to accessibility than other vendors, or even than elsevier’s tutorials for other elsevier products. the science direct tutorials were not accessible, but an alternate text version was available and people using screen-reader software were informed of this when they get to the tutorial page and were redirected to the text version. the ideal is to have one version that is accessible to everyone, but this approach is a good way to implement an alternate version if one accessible version isn’t possible. screencasts or video tutorials from other vendors also have some good accessibility features, but these were balanced with serious accessibility problems. the main accessibility issues discovered include the following: alternate accessible versions: vendors who had captions and hosted their videos on youtube did have auto-generated youtube transcripts, but these were hard to find and were only useful if the captions were descriptive and accurate, which many were not. apart from elsevier’s sciencedirect tutorials, no vendors provided another format deliberately as an accessible alternative. captions: captions were missing or problematic in the tutorials of fourteen vendors, or 59 percent of the total. five (21 percent) of vendors provided no captions at all for their tutorials. nine (38 percent) had unedited, auto-generated youtube captions, which are highly inaccurate and therefore don’t provide usable access to the content for people who are deaf. tutorial not findable or playable on page: twelve vendors (50 percent) had tutorials that were not findable on the webpage or playable for people using a keyboard or screenreading software. most of these issues are with tutorials on vendor sites, which were often flash-based or offered through non-youtube third party sites like vimeo. four vendors (17 percent) offered access to their tutorials both through their own (inaccessible) website and youtube, which is findable and playable by screen reading software. eight (33 percent), however, only provided access through their (inaccessible) webpages, which means that people using a keyboard or screen reading software would not be able to use their tutorials. no visual cues to focus attention: eight vendors (33 percent) had no visual cues to focus attention in the video. visual cues help people with certain disabilities focus on the essential part of the screen that is being discussed, help everyone more easily interpret and follow what is happening, and are known to help facilitate successful multimedia learning.18 information technology and libraries | december 2016 13 nondescriptive narration: six vendors (25 percent) had tutorials with audio narration that didn’t sufficiently describe what was happening on the screen. narration needs to describe what is happening in enough detail so people who can’t see the screen are not missing information available for sighted viewers. fuzzy visuals: five vendors (21 percent) had tutorials with visuals that were fuzzy and hard to see. this makes viewing difficult for people with low vision, and challenging even for people with normal vision. fuzzy audio or background music: three vendors (13 percent) had poor-quality audio narration or background music playing during narration. background music is distracting for those with hearing difficulties and makes it more difficult to focus on what is being said. eliminating extraneous sound also makes it easier for people to learn from multimedia.19 tutorials consisting only of text captions: three vendors (13 percent) had tutorials consisting of text captions with no narration. the text captions were not readable by screen-reading software, and no alternate accessible versions were provided. providing narration in tutorials is recommended for accessibility, since it allows people who can’t see the screen to access the content more easily, and has been shown to improve learning and recall over on-screen text and graphics alone.20 recommendations and conclusions this study attempted to determine how accessible vendor-created database tutorials are, and whether academic librarians can use them instead of re-creating them locally. for recorded webinars, the answer is a clear no, since none were technically accessible for people using screenreading software. for video or screencast tutorials, however, the answer less is clear. results showed that many vendors created tutorials with positive features like clear visuals and audio, being short and focused on one main point, and using descriptive narration. however, technical accessibility was much less successful, with 59 percent of vendors omitting usable captions and 50 percent presenting tutorials that couldn’t be found on the page or played by people using screen-reading software. these technical accessibility issues prevent people with hearing, vision, or some mobility impairments from using the tutorials at all. although none of the tutorials studied met all the checklist criteria, some came close and could be used by librarians depending on local requirements, policies, and priorities for accessibility. in part, this study found that the accessibility of many tutorials depends on how they are presented. disappointingly, 50 percent of vendors had tutorials on their websites that were not findable or playable by people with disabilities. many vendors, however, hosted tutorials on youtube as well as their own site. in these cases, youtube was always a more accessible option accessibility of vendor-created database tutorials for people with disabilities | oud https://doi.org/10.6017/ital.v35i4.9469 14 than the vendor site. youtube itself is relatively accessible, with both pages and players that are navigable by keyboard and by screen-reading software. there are options for accessibility settings in youtube, such as having captions display automatically, and more accessible third-party overlays are available for the youtube player. on vendor sites, there were more likely to be issues with flash and an inability for people using screen-reading software or keyboards to find and play videos. some vendors embed youtube videos on their site. even if the embedded videos are findable and playable, this method omits important accessibility features found on the youtube page, such as the text transcript. the results of this study show that using youtube where available is recommended. further, linking to youtube rather than embedding the video is preferred, unless a separate link to the transcript is made to provide an alternate accessible version. captions are another key accessibility problem identified in this study: nearly two-thirds had unusable captions. often, auto-generated youtube captions were present but were not usable. the presence of captions is not enough for accessibility; those captions need to be accurate and present the same content as the narration. youtube auto-captioning does not generate captions that are accurate enough to be useful without manual editing. youtube auto-generates transcripts from the captions, so if the captions are inaccurate the transcript will not be useful either. editing youtube auto-generated captions is necessary to ensure accessibility. a few accessibility issues found in this study would be easy to improve with some thought during tutorial creation. adding visual cues like arrows or highlighting to the screen to help people focus attention, or remembering that not everyone can see the screen while recording narration, can be easily achieved and would improve accessibility significantly. other issues would require more planning and effort to improve. given the widespread technical accessibility problems identified in this study, it is particularly important for people creating tutorials to provide alternate formats that are accessible if tutorials themselves are not accessible. almost no vendors do this currently, but it would have the most significant impact on accessibility for the broadest range of people. adding usable captions is the second most important area for improvement. to provide access for people who are deaf, captions need to be added or autogenerated youtube captions need to be edited for accuracy. both alternate formats and captions require some thought and effort to implement but ensure that tutorials will meet accessibility requirements and be usable by everyone. notes and

(one difficulty is that the vocabulary used to classify the numeric data is ordinarily quite different from the subject headings used for books, magazine articles, and newspaper stories about the same topic.) second, when intriguing data values are encountered, one would like to move directly to topically relevant texts. likewise, when a questionable statement is read, one would like to be able to find relevant statistical evidence. therefore, there needs to be search support that facilitates such transverse searching among resources, establishing connections, transferring data, and invoking appropriate utilities in a helpful way. both problems were addressed through the design and demonstration of a gateway providing search support for both text and socioeconomic numeric databases. first, the gateway should help users conduct searches in databases of different media forms by accepting a query in the searcher’s own terms and then suggesting the specialized categorization terms to search for in the selected resource. second, if something interesting was found in a socioeconomic database, the gateway would help the searcher to find documents on the same topic in a text database, and vice versa. selection of the best search terms in target databases is supported by the use of indexes to the categories (entries, headings, class numbers) in the system to be searched. these search-term recommender systems (also known as “entry vocabulary indexes”) resemble dewey’s “relativ index,” but are created using statistical association techniques.2 four characteristics of this investigation need to be noted: 1. searching independent sources: the authors were not concerned with ingesting resources from different sources into a consolidated local data repository and searching within it. the interest lay, instead, in being able to search effectively in any accessible resource as and when one wants. this implies that interoperability issues in dealing with the native query languages and metadata vocabularies of remote repositories can be solved. 2. search for independent content: numeric data sets commonly have associated text in the form of documentation, code books, and commentary. however, the authors were interested in finding topical content that had no such formal or literary connection. independent means, for example, a newspaper article written by someone unaware that relevant statistical data existed or had been written before the author’s article existed. in the other direction, having found statistical data of interest, could topically related text created independently of this particular data point be found? 3. two different media forms were chosen: text and numeric data sets. they look similar because they both use arabic numerals, but the traditional reliance on information retrieval in a text environment search across different media: numeric data sets and text files michael buckland, aitao chen, fredric c. gey, and ray r. larson michael buckland (buckland@sims.berkeley.edu) is emeritus professor, school of information, university of california, berkeley; aitao chen (aitao@yahoo-inc.com) is a researcher at yahoo!, sunnyvale, california; fredric c. gey (gey@berkeley .edu) is an information scientist, uc data archive and technical assistance at the university of california, berkeley; and ray r. larson (ray@sims.berkeley.edu) is a professor, school of information at the university of california, berkeley. 182 information technology and libraries | december 2006 of using any character string from the corpus as a query, although technically feasible, cannot be expected to be useful here. one can copy a number expressing quantity, such as 12,941, from a numeric data cell, use it as a query in a text search engine such as google, and retrieve a large and eclectic retrieved set, usually involving “12941” as an identifying number for a postal code, a memorandum, a part number, software bug report, and so on, but the relationship is spurious. it requires great faith in numerology to expect anything topically meaningful to the original data cell one started with. with other combinations of media forms, not even spurious results are feasible: one cannot submit a musical fragment or some pixels from an image as a text query. 4. the authors’ interest was in how to achieve a better return on existing investments in well-formed, edited resources with descriptive metadata. this project built directly on prior work on how to make more effective use of existing, expertly developed metadata, rather than creating or replacing metadata. search of multiple resources comes in two forms: 1. parallel search is when a single query is sent to two or more resources at more or less the same time. for example, a researcher interested in the import of shrimp would like to see pertinent newspaper articles and trade statistics. thus, one might send a query to the census bureau’s united states (u.s.) imports and exports numeric data series and look at sic 0913 for shrimp and prawn and note a dramatic increase in imports from vietnam through los angeles from 1995 onwards. one would also search newspaper indexes for articles such as “normalizing ties to vietnam important steps for u.s. firms; california stands to profit handsomely when barriers fall to trade with fast-growing country.”3 different sources are likely to use different index terms or categories, so the challenge is how to express the searcher’s query in terms that will be effective for searching in the target resources, which, mostly likely, will use different vocabularies. as one example, the term for “automobiles” is 3711 in the standard industrial classification; tl 205 in the library of congress (lc) classification, 180/280 in the u.s. patent classification; and, in the census bureau’s u.s. imports and exports data series, pass mot veh, spark ign eng.4 2. transverse search is when an item of interest found in one resource is used as the basis for a query to be forwarded to a different resource. the challenge here, again, is that when a query using the topical metadata in one resource needs to be expressed in the vocabulary of the target resource, the metadata vocabularies in the two resources will usually be different from each other, and, quite likely, both are unfamiliar to the searcher. when searching within a single media form, it may be possible to use content itself directly as a query: a fragment of text in a source-text database is commonly used as a query in a target-text database. similarly, one might start with an image and seek images that are measurably similar. however, because such direct search cannot be done when searching across different media forms, an indirect approach relying on the use of interpretive representations becomes necessary. as the network environment expands, mapping between vocabularies will be increasingly important. ■ text and numeric resources text resource a library catalog—a special case of text file—was chosen for use as a text file rather than a corpus of “full text.” the reasons were practical: in this exploratory investigation, it was important to start with resources that had rich metadata; it needed to be a resource that was sufficiently controllable to enable experimentation with it. a library catalog was in the spirit of the project in that it would lead to additional text resources; and a suitable resource was available, which was intended for metadata mapping: a set of several million marc records, derived from melvyl, the university of california online library catalog. socioeconomic numeric data set initially, and in prior work, the authors had worked on access to u.s. federal data series, especially import and export statistics and county business reports. although some progress was made with interfaces to these data series, it became clear that the investment needed to craft interoperable access was high relative to the available staff. crafting access to individual data series did not appear to be a scalable way to demonstrate variety within the authors’ limited resources, so attention was turned to a single collection comprising many diverse numeric tables, the counting california database.5 ■ mapping topical metadata well-edited, high-quality databases typically have topical metadata expertly assigned from a vocabulary (thesaurus, classification, subject-heading system, or set of search across different media | buckland, chen, gey, and larson 183 categories). but there is a babel of different vocabularies. not only do the names of topics vary, but the underlying concepts or categories may also differ. effective searching requires expert familiarity with a system’s vocabulary; but as access to digital resources expands, the diversity of vocabularies increases and accessible resources are decreasingly likely to use vocabularies familiar to any individual searcher. the best answer is twofold: first, it is desirable to have an index (a “mapping”) from the natural language of each group of searchers to the entries used in each metadata vocabulary. such a mapping provides an index from a vocabulary familiar to the searcher to the vocabulary used in entries of the target system and so is called a search-term recommender system. (the authors called it an “entry-vocabulary index,” or evi.) dewey’s “relativ index” to his decimal classification is a familiar example. when searching across databases, one also wants a second kind of mapping: between pairs of system vocabularies. unfortunately, mappings between different vocabularies are rare, expensive, time-consuming, and hard to maintain. (the unified medical language system is a notable example.)6 it is the authors’ impression that this problem is worse in searching across different media forms because data bases in different media forms tend to be created by different communities, increasing the chances that they will use different categories, vocabularies, and ways of thinking. fortunately where data containing two forms of vocabulary are available, they can be used as training sets for statistical-association techniques to generate evis automatically, and this is the approach that was used. (more details can be found in the appendix.) from text words to library subject headings an evi from ordinary english words to library of congress subject headings (lcsh) was created by taking catalog records containing at least one subject heading (6xx field in the marc bibliographic format). from each of the 4,246,510 records used, main subject headings were extracted (subfield a from fields 600, 610, 611, 630, 650, and 651) and fields containing text: titles (245a), subtitles (245b), and summaries describing the scope and general content of the material (520a). the underlying assumption is that for each record, the words in the “text” fields (245a,b and 520a) tend to be characteristic of discourse on the subject (6xxa). two examples, with identifying lccns in the <001> field are: <001>73180254 //r86</001> <245><a>a study of operant conditioning under delayed reinforcement in early infancy</a></245> <650><a>infant psychology</a></650> <650><a>operant conditioning</a></650> <001>73180255 </001> <245><a>reptilian disease</a><b>recognition and treatment</b></245> <650><a>reptiles</a><x>diseases</x></650> the words in the text fields (245a, 245b, and 520a) were extracted. stop words were removed and the remainder normalized. then the degree to which each word is associated with each subject heading (by co-occurring in the same records) was computed using a maximum likelihood ratio-based measure. natural-language processing can be used to identify adjective-noun phrases to support more precise searching using phrases as well as individual words. a very large matrix shows the association of each text word (or phrase) with each subject heading; so, for any given word (or combination of words), a list of the most closely associated headings, ranked by degree of association, can be derived from the matrix. queries a query, which can be a single word, a phrase, a set of keywords, a book title, and so on, is normalized in the same way and looked up in the matrix to produce a ranked list of the most closely associated subject headings as candidate lcsh search terms. for example, entering the textual query words “peanut” and “butter” generates the following ranking list of lcsh main headings as candidates for searching: rank lcsh (subfield 650a) 1. peanut 2. cookery (peanut butter) 3. cookery (peanuts) 4. peanut industry 5. peanut butter 6. butter 7. schulz, charles m. this display is an important departure from traditional fully automatic searching. the list is, in effect, a prompt, indicating probably suitable query terms in the vocabulary of the target resource. it introduces the searcher to the categories and terminology of the system and enables the searcher to use expert judgment to select the heading that seems best for the search. from text words to the metadata vocabularies in numeric data sets a training set of records containing both descriptive words and topical metadata is often not readily available for numeric data sets. the authors’ first effort was to create an evi to the standard industrial classification (sic), widely used over many years in numeric data sets. (sic codes were associated with words by using, as a training set, the 184 information technology and libraries | december 2006 titles in a bibliographic database that used sic codes.) but by the time the sic evi was completed, sic had been discontinued and replaced by the north american industry classification system (naics), so a mapping was created from sic codes to naics codes. figures 1–3 show stages in an interface that accepts a searcher’s query “car” (figure 1), prompts with a ranked list of naics codes (figure 2), then extends the search with the selected naics code to retrieve numeric data (figure 3). by this time, however, it had become apparent that, with the current low level of interoperability in software and in data formats, the labor required to create evis and interfaces to each large traditional numeric data series was enormous. therefore, attention was turned to a collection of different numeric data sets available through a single interface, counting california, made available by california digital library at http://countingcalifornia.cdlib.org. this resource is a collection of some three thousand numeric tables containing statistics related to a range of topics. the numeric data sets are mainly from the california department of health services, the california department of finance, and the federal bureau of the census. the tables are organized under a two-level classification scheme. there are sixteen topics at the top level, which are subdivided into a total of 184 subtopics. all the numeric tables were assigned to one or more subtopics and each table has a caption. at the counting california web site, a searcher can browse for tables by selecting a higher-level topic, then a lower-level subtopic, and then a table. two additional ways were created to access the tables: probabilistic retrieval, and an evi to the topical categories. the captions, topics, and subtopics were extracted for each of the three thousand tables, and xml records were created in the following form: <table> <topic> education </topic> <subtopic> libraries </subtopic> <caption> library statistics, statewide summary by type of library california 1992–93 to 1997–98 </caption> </table> retrieval two search methods were used: direct probabilistic retrieval. an in-house implementation was used of a probabilistic full-text retrieval algorithm developed at berkeley.7 this search engine takes a free-form text query and returns a ranked list of captions of tables ranked according to their relevance scores. for example, the five top-ranked captions returned to the query “public libraries in california” were: figure 1. query interface for search-term recommender system f or the north american industry classification system figure 2. display of naics code search-term recommendations for “car” figure 3. display of numeric data retrieved using selected naics code search across different media | buckland, chen, gey, and larson 185 1. library statistics,

in the retrieved set list is linked to a numeric table maintained at the counting california web site and, by clicking on the appropriate link, a user can display the table as an ms excel file or as a pdf file. mediated search. from the same extracted records the words in the captions were used to create an evi to the subtopics in the topic classification using the method already described. as an example, the query “personal individual income tax,” when submitted to the evi, generated the following ranked list of subtopics: 1. income 2. government earnings and tax revenues 3. personal income 4. property tax 5. personal income tax 6. corporate income tax 7. per capita income a user can click on any selected subtopic to retrieve the captions of tables assigned that subtopic. for example, clicking on the fifth subtopic, personal income tax, retrieves: ■ personal income tax returns: number and amount of adjusted gross income reported by adjusted gross income class california, 1998 taxable year. table d10yr00 ■ personal income tax returns: number and amount of adjusted gross income reported by adjusted gross income class california, 1997 taxable year. table d9 ■ personal income statistics by county, california 1997 taxable year. table d10 ■ personal income statistics by county, california 1998 taxable year. table d11yr00 ■ transverse searching between textand numeric-data series to demonstrate the searching capability from a bibliographic record to numeric-data sets, the first step is to retrieve and display a bibliographic record from an online catalog. a web-based interface for searching online catalogs was implemented using an in-house implementation of the z39.50 protocol. besides the z39.50 protocol, an important component that makes searching remote online catalogs feasible is the gateway between the http (hypertext transfer protocol) and the z39.50 protocol. while http is a connectionless-oriented protocol, the z39.50 is a connection-oriented protocol. the gateway maintains connections to remote z39.50 servers. all search requests to any remote z39.50 server go through the gateway. searching from catalog records to numeric data sets having selected some text (for the purposes of this study, a catalog record), how could one identify the facts or statistics in a numeric database that are most closely related to the topic? clicking on a “formulate query” button placed at the end of a displayed full marc record creates a query for searching a numeric database. the initial query will contain the words extracted from the title, subtitle, and the subject headings and is placed in a new window where the user can modify or expand the query before submitting it to the search engine for a numeric database. so, for example, the following text extracted from a catalog record: library laws of the state of california, library legislation. california. public libraries when submitted as a query, retrieves a ranked list of table names, of which two, covering different time periods, are entitled library statistics, statewide summary by type of library, california. searching from numeric data sets from catalog records transverse search in the other direction, starting from a data table, is achieved by forwarding the caption of a table to the word-to-lcsh evi to generate a prompt list of the seven top-ranked lchss, any one of which can be used as a query submitted to the catalog. ■ architecture figure 4 shows the structure of the implementation. the boxes shown in the figure are: 1. a search interface for accessing bibliographic/textual resources through a word-to-lcsh evi. 2. a word to the lcsh evi. 3. a ranked list of lcshs closely associated with the query. 4. an online catalog. 186 information technology and

a search interface for numeric databases based on a probabilistic search algorithm. a user can start a search using either interface (boxes 1 or 11) and, from either starting point, find records on the same topic of interest in a textual (here bibliographic) database and a socioeconomic database. ■ conclusions and further work enhanced access to numeric data sets the descriptive texts associated with numeric tables, such as the caption, headers, or row labels, are usually very short. they provide a rather limited basis for locating the table in response to queries, or describing a data cell sufficiently to form a usefully descriptive query from it. sometimes the title (caption) of a table may be the only searchable textual description about the content of the table, and the titles are sometimes very general. for example, one of the titles, library statistics, statewide summary by type of library california, 1992–93 to 1997–98, is so general that neither the kinds of statistics nor the types of libraries are revealed. if a user posed the question, “what are the total operating expenditures of public libraries in california?” to a query system that indexes table titles only, the search may well be ineffective since the only word in common between the table title and the user’s query is “california” and, if the plurals of nouns have been normalized, to the singular form, “library.” table column headings and row headings provide additional information about the content of a numeric table. however, the column and row headings are usually not directly searchable. for example, a table named “language spoken at home” in counting california databases consists of rows and columns. the column headings list the languages spoken at home, while the row headings show the county names in california. each cell in the table gives the number of people, five years of age and older, who speak a specific language at home. to answer questions such as “how many people speak spanish at home in alameda county, california?” using the table title alone may not retrieve the table that contains the answer to the example question. it is recommended that the textual descriptions of numeric tables be enriched. automatically combining the table title and its column and row headings would be a small but practical step toward improved retrieval. geographic search socioeconomic numeric data series refer to particular areas and, in contrast to text searching, the geographical aspect ordinarily has to be specified. to match the geographical area of the numeric data, a matching text search may also have to specify the same place. the authors found that this was hard to achieve for several reasons. place names are ambiguous and unstable: a search for data relating to trinidad might lead to trinidad, west indies, instead of trinidad, california, for example. the problem is compounded because, in numeric data series, specialized geopolitical divisions, such as census tracts and counties, are commonly used. these divisions do not match conveniently with searchers’ ordinary use of place names. also, the granularity of geographical coverage may not match well. data relating to berkeley, for example, may be available only in aggregated data for alameda county. it was eventually concluded that reliance on the names of places could never work satisfactorily. the only effective path to reliable access to data relating to places would be to use geospatial coordinates (latitude and longitude) to establish unambiguously the identity and location of any place and the relationship between places. this means that gazetteers and map visualizations become important. gazetteers relate named places to defined spaces, and thereby reveal spatial relationships between places, e.g., the city of alameda is on alameda island within alameda county. this problem has been addressed in a subsequent figure 4. architecture of the prototype search across different media | buckland, chen, gey, and larson 187 study entitled “going places in the catalog: improved geographical access.”8 temporal search searches of text files and of socioeconomic numeric data series also differ substantially with respect to time periods: numeric data searches ordinarily require the years of interest to be specified; text searches rarely specify the period. an additional difficulty arises because in text, as in speech, a period is commonly referred to by a name derived metaphorically from events used as temporal markers, rather than by calendar time, as in “during vietnam,” “under clinton,” or “in the reign of henry viii.” named time periods have some of the characteristics of place names: they are culturally based and tend to be multiple, unstable, and ambiguous. it appears that an analogous solution is indicated: directories of named time periods mapped to calendar definitions, much as a gazetteer links place names to spatial locators. this problem is being addressed in a subsequent study entitled “support for the learner: what, where, when, and who.”9 media forms the paradox, in an environment of digital “media convergence,” that it appears impossible to search directly across different media forms invites closer attention to concepts and terminology associated with media. a view that fits and explains the phenomena as the authors understand them, distinguishes three aspects of media: ■ cultural codes: all forms of expression depend on some shared understandings, on language in a broad sense. convergence here means cultural convergence or interpretation. ■ media types: different types of expression have evolved: texts, images, numbers, diagrams, art. an initial classification can well start with the five senses of sight, smell, hearing, taste, and feel. ■ physical media: paper; film; analog magnetic tape; bits; . . . being digital affects directly only this aspect. anything perceived as a meaningful document has cultural, type, and physical aspects, and genre usefully denotes specific combinations of code, type, and physical medium adopted by social convention. genres are historically and culturally situated. convergence can be understood in terms of interoperability and is clearly seen in physical media technology. the adoption of english as a language for international use in an increasingly global community promotes convergence in cultural codes. nevertheless, the different media types are fundamentally distinct. metadata as infrastructure it is the metadata and, in a very broad sense, “bibliographic” tools that provide the infrastructure necessary for searches across and between different media—thesauruses, mappings between vocabularies, place-name gazetteers, and the like. in isolation, metadata is properly regarded as description attached to documents, but this is too narrow a view. collectively, the metadata forms the infrastructure through which different documents can be related to each other. it is a variation on the role of citations: individually, references amplify an individual document by validating statements made within it; collectively, as a citation index, references show the structure of scholarship to which documents are attached. ■ summary a project was undertaken to demonstrate simultaneous search of two different media types (socioeconomic numeric data series and text files) without ingesting these diverse resources into a shared environment. the project objective was eventually achieved, but proved harder than expected for the following reasons: access to these different media types has been developed by different communities with different practices; the systems (vocabularies) for topical categorization vary greatly and need interpretative mappings (also known as relative indexes, searchterm recommender systems, and evis); specification of geographical area and time period are as necessary for search in socioeconomic data series and, for this, existing procedures for searching text files are inadequate. ■ acknowledgement this work was partially supported by the institute of museum and library services through

the stopwords were removed; and the remaining words were normalized. a token here can contain only letters and digits. all tokens were then changed to lower case. the stoplist has about six hundred words considered not to be content bearing, such as pronouns, prepositions, coordinators, determiners, and the like. the content words (those not treated as stopwords) were normalized using a table derived from an english morphological analyzer.2 the table maps plural nouns into singular ones; verbs into the infinitive form; and comparative and superlative adjectives to the positive form. for example, the plural noun printers is reduced to printer, and children to child; the comparative adjective longer and the superlative adjective longest are reduced to long; and printing, printed, and prints are all reduced to the same base form print. when a word belonging to more than one part-of-speech category can be reduced to more than one form, it is changed to the first form listed in the morphological analyzer table. as an example, the word saw, which can be a noun or the past tense of the verb to see, is not reduced to see. subject headings (field 6xxa) were extracted without qualifying subdivisions. the inclusion of foreign words (alcoholismo, alcoolisme, alkohol, and alcool), derived from titles in foreign languages, demonstrate that the technique is language independent and could be adopted in any country. it could also support diversity in u.s. libraries by allowing searches in spanish or other languages, so long as the training set contains sufficient content words. evis are accessible at http://metadata. sims.berkeley.edu/prototypesi.html. fuller descriptions of the project methodology can be found in the literature.3 ■ references 1. ted dunning, “accurate methods for the statistics of surprise and coincidence,” computational linguistics 19 (march 1993): 61–74. 2. daniel karp et al., “a freely available wide coverage morphological analyzer for english,” in proceedings of coling-92, nantes, 1992 (morristown, n.j.: association for computational linguistics, 1992), 950–55, http://acl.ldc.upenn .edu/c/c92/c92-3145.pdf (accessed july 18, 2006). 3. michael k. buckland, fredric c. gey, and ray r. larson, seamless searching of numeric and textual resources: final report on institute of museum and library services national leadership grant no. 178 (berkeley, calif.: univ. of california, school of information management and systems, 2002), http://metadata.sims .berkeley.edu/papers/seamlesssearchfinalreport.pdf (accessed jul. 18, 2006);

(2015) presented an approach related to information literacy instruction in universities and colleges that combines traditional classroom instruction and online learning; this is known as “blended learning.”8 this involves only one seminar in the classroom; thus, it can replace traditional sessions at universities and colleges with education involving information literacy instructions. it has been recommended that a time-efficient method should be adopted by augmenting classroom seminars and literacy instructions through the addition of online materials. however, the findings of this study showed that students who only use online materials do not show greater progress in their learning than those who follow the blended approach. the results of another study by jackson more effectively integrated educational services into learning management systems and library resources.9 jackson suggested that better implementation was required, and recommended using blackboard lms to include information literacy and scaffolding activities into subject-specific courses. this study intends to determine the most effective method of information literacy education. it evaluates instructors’ and students’ perceptions of the effectiveness of traditional teaching in comparison to electronic teaching in information literacy. in this study, a quantitative research investigation was conducted with participants. a research model and questionnaire were developed for this purpose with three underlying latent variables. the participants were asked to describe their understanding of learning systems and their preferences in information literacy education. their requirements varied with their continuing education levels and past educational activities, based on which software or website appeared to be more supportive and compatible with them.10 this study considered the research results, developed an information literacy intervention model and applied it to a case study. literature review previously, educational institutions were limited to face-to-face teaching techniques or classroombased teaching. face-to-face teaching is the traditional method still used in most educational institutions. in classrooms, the subject is explained, and books or other paper-based materials are read out of class to enhance understanding.11 face-to-face learning or teaching is limited by the number of physical resources available. therefore, it becomes difficult to accommodate the widespread interest in information literacy through face-to-face learning.12 gathering information using only physical resources can lead to information deficiencies.13 education has evolved to benefit from advances in technologies by using lms and online sources. the effective usage of lms and online sources requires the development of information literacy. information technology and libraries | december 2018 121 information literacy information literacy includes technological literacy, information ethics, online library skills, and critical literacy.14 technological literacy is defined as the ability to use common software, hardware, and internet tools to reach a specific goal. this ability is an important component of information literacy that enables a graduate to seek answers by using the internet and digital resources.15 hauptman defines information ethics as “the production, dissemination, storage, retrieval, security, and application of information within an ethical context.”16 this skill is essential to preserve the original rights of researchers cited in a study, based on the ethical standards of the graduate conducting the study. another important component of information literacy comprises online library skills, which can be defined as the ability to use online digital sources, including digital libraries, to effectively seek different knowledge resources by using search engines, correctly locating required information, and using online support when needed.17 critical literacy is a thorough evaluation of online material that allows for the appropriate conclusion to be reached on the suitability of the material for the required investigation. 18 seeking answers from appropriate sources is important to allow graduates to find and report on accurate and valid data. these components of information literacy enable information extraction from topics related to the desired course or field of research. students, professors, instructors, employees, learners, and educational policy administrators are the major knowledge seekers who use information literacy skills.19 with improved online resources available for learning, many learning requirements are moving toward providing services that are exclusively online. 20 gray and montgomery studied an online information literacy course.21 they found that teaching with the aid of information literacy is helpful for students in obtaining improvised instruction. the authors also compared an online information literacy course and face-to-face instruction, focusing primarily on the behaviors and attitudes of teachers and college students toward the online course. the students agreed that the application of information literacy techniques would be particularly helpful to them in clarifying their understanding of complicated instructions. the teachers also indicated that an information literacy course would result in better regulation of academic processes than face-to-face learning. dimopoulos et al. (2013) measured student performance within an online learning environment, finding that the online learning environment has direct relevance for the completion of challenging tasks within academic settings.22 the findings further indicated that an lms could improve teaching activities. as an lms, moodle was also helpful for students to ensure their development of collaborative problem-solving skills. they concluded that moodle includes different useful modules such as digital resource repositories, interactive wikis, and external addin tools that have been related to student learning when incorporated into the lms environment, resulting in better performance. hernández-garcía and conde-gonzález focused on learning analytical tools within engineering education, noting that engineering students are more likely to understand complicated concepts better. therefore, the application of the information literacy model resulted in better performance.23 further, educating students about information sources was found to be helpful for the instructors in enhancing the students’ learning by improving their online information retrieval skills. this study indicated that students can develop their learning traits more effectively through online learning than through face-to-face learning. information literacy model | abunadi 122 https://doi.org/10.6017/ital.v37i4.9750 many researchers in this area have developed models that are only theoretical. 24 however, this paper develops a practical information literacy model that can be tested for improvement in information literacy skills. this is especially relevant for computer and information systems courses, which can sometimes fall outside the purview of library-related training or education in universities with limited resources. the inclusion of information literacy training within computer and information systems courses is not regularly done in the information literacy field. 25 additionally, although some information literacy has been implemented practically in research, no other study has developed a practical information literacy model based on educators’ and students’ information literacy dispositions as well as both information literacy theory and practice.26 moodle as an lms moodle is a useful and accommodating open-source platform with a stable structure of website services that allows instructors and learners to implement a range of helpful plugins. it can be used as a lively online education community and an enhancement to the face-to-face learning process.27 moodle is used in around 190 countries and offers its services in over seventy languages. it acts as a mediator for instruction and is widely adopted in many institutions. moodle provides services such as assignments, wikis, messaging, blogs, quizzes, and databases. 28 it can provide a more flexible teaching platform than traditional teaching. health science educational service providers facilitate self-assurance in their learners. several educational campuses operate by using face-to-face learning strategies, whereby learners obtain their training on-campus locations. the objective of moodle is to enable the education of learners through internet access.29 xing focused on the broad application of the moodle lms for developing educational technology within academic settings, suggesting that academic organizations should promote technology as a solution for common problems with students’ learning processes.30 such suggestions have been supported by costa et al. (2012) who found that moodle is significantly helpful for developing an e-learning platform for students. they emphasized that engineering universities must use the moodle lms to provide students with extensive technical knowledge. 31 costello et al. (2012) stated that moodle, if used, will significantly help students improve their skills and knowledge effectively.32 methodology in information literacy skill development, there are studies that support using only face-to-face education or only using an lms. for example, churkovich and oughtred found that face-to-face learning leads to better results in information literacy tutorials than online learning. 33 at the same time, anderson and may concluded that the use of an lms is viewed by students as a better method than face-to-face instruction in information literacy.34 to test which educational pedagogy (traditional or technology) is better regarding information literacy, the following two hypotheses were posited: h1: face-to-face learning has a significantly positive influence on information literacy disposition. h2: moodle learning has a significantly positive influence on information literacy disposition. to provide a better understanding of the most effective method of information literacy instruction, a quantitative research design was used. the wording of the questionnaire items (shown in table 1) was inspired by the studies of ng, horvat et al., abdullah, and deng and tavares. 35 online information technology and libraries | december 2018 123 questionnaires were prepared and distributed to students, teachers, trainers, and professors as well as administrative departments in a small private university located in the arabian gulf region. initially, a pilot study was conducted to test the instrument. this pilot study involved forty-nine participants and fifteen questions on information literacy. it also included demographic questions. variables code item wording face-to-face education disposition (fed) fed1 information literacy

questionnaire was sent to the management of an academic institution in the arabian gulf region to assess the instruction methodology to improve students’ information literacy skills. the language used in the survey was arabic, and the questionnaire was translated into english for this article by a professional translator. a total of five hundred questionnaires were sent, and 398 of them were received with complete responses. the following criteria were used to filter questionnaires that were not appropriate for this study: inclusion criteria • people currently involved in the education system. • students, teachers, or members of an academic department. • people who understand information literacy. a question was added in the survey about whether the participant was familiar with information literacy; if not, the participant was removed from the sample. exclusion criteria • people who were not involved in the education system. • people who were not aware of online learning systems. • staff with no role in learning or teaching. information literacy model | abunadi 124 https://doi.org/10.6017/ital.v37i4.9750 gender frequency percent male 186 46.73 female 212 53.27 total

reliability statistics showed a high level of consistency for the pilot test because the cronbach’s alpha for the fifteen items was 0.901, which is above the recommended level of 0.7.36 cronbach’s alpha is a widely used coefficient measuring the internal consistency of items as a unified group.37 information technology and libraries | december 2018 125 based on the successful pilot study, a full-scale study was conducted. the demographic distribution for the full-scale study is shown in table 2 along with the mean and standard deviation of each demographic factor. the distribution of the questionnaire items for the full-scale study is shown in tables 3 and 4. cronbach’s alpha was used to determine the reliability of the constructed items for the full-scale study. the standard benchmark for the reliability value is a 0.7 threshold; however, the cronbach’s alpha for all constructed items was above the 0.7 standard value. thus, this standard score revealed that all the items had appropriate and adequate reliability.38 results the research hypotheses were tested using structural equation modeling (sem) with the analysis of momentum structures (amos) approach. sem includes various statistical methods and computer algorithms that are used to assess latent variables along with observed variables. sem also indicates the relationships among latent variables, showing the effects of the independent variables on the dependent variables.39 one well-regarded sem methodology is amos, which is a multivariate technique that can concurrently assess the relationships between latent variables and their corresponding indicators (measurement model), as well as the relationships among the model’s variables.40 highly cited information systems and statistics guidelines were followed for the sem to ensure the validity and reliability of data analysis. 41 measurement and structural model the measurement model contained fifteen items for ascertaining the representation of three latent variables, including face-to-face education disposition, moodle usage disposition, and information literacy preferences. before we proceed to this analysis, the data need to show normality for us to be able to trust the robustness of this parametric sem. curran et al. suggested a skewness and kurtosis less than the absolute value of 2 and 7, respectively, to display the normality of the data.42 all items’ absolute values of skewness and kurtosis were less than the suggested cut off, showing a suitable level of normality for conducting sem analysis. the overall measurement model showed a high level for the fit indices: gfi=0.99, agfi=0.98, nfi=0.98, cmin/df=0.86, and rmr=0.39. all these fit indices show that the theoretical model fits well with the empirical data if they are above 0.95, except cmin/df and rmr, which do not follow this cut off. the cmin/df should be less than 3, while the rmr should be less than 0.5.43 table 5 shows all the items loaded on their corresponding latent variables higher than the suggested cut off (0.5). as shown in the table, il6 was the only item that did not load clearly on its latent variable and, thus, it was dropped from further analysis.44 an additional method to assess item loading was item loading significance, which was significant at the level of 0.001, indicating that all items loaded on their latent variables.45 the indices of the measurement model suggested that the psychometric properties of this instrument can be preceded by the structural model. information literacy model | abunadi 126

was used to evaluate the hypothesized relations between the dependent variables (face-to-face education disposition [fed] and moodle usage disposition [mud]) and independent variables (il). both education methods were tested in the hypotheses to identify the most suitable information literacy delivery mode for students. both hypotheses were supported, which indicates that an individual method of information literacy delivery (either face-to-face instruction or lms) is not preferred, and a different model can be suggested. both hypotheses were supported at the level of 0.001 with an effect size for face-to-face education disposition of 0.32, which indicates a medium impact on information literacy preferences. meanwhile, the moodle usage disposition had an effect size of 0.70, which is considered a large effect size (hair et al. 2010). finally, the model’s explanatory power of information literacy preferences was determined by r2, which was high (0.85). based on the previous analysis, it can be said that an individual method of information literacy delivery is insufficient in developing countries. thus, a different model for information literacy was developed (figure 1), which had an impact on students’ related competencies. information technology and libraries | december 2018 127 figure 1. information literacy intervention model. as shown in figure 1, the model includes conducting weekly information literacy sessions that focus on educating students about technological literacy, information ethics, online library skills, and critical literacy. after each session is concluded, the instructor creates weekly assignments using an lms that tests the students’ information literacy abilities regarding the subject material. the instructor follows up regarding the students’ overall performance and fills any identified gaps in subsequent information literacy sessions and assignments. the instructor studies the students’ performance after one month and provides feedback to students. finally, a “real case project assignment” is used to teach students to solve real problems using the skills they learn. the instructor can further extend reflection on the process of assigning “real case project” grades by creating a course exit survey that asks students about their acquired level of information literacy skills. longitudinal case study a small technical university in the arabian gulf region faces difficulties in providing adequate library resources to its students because of its limited capabilities. the university has about 4,500 students and five hundred employees. the university library and information technology department shortage in adequate staff and resources, resulting in an insufficient support for student learning. this has caused lack of student information literacy education, which is evident in the submission of student assignments. for example, students are not accustomed to citing materials that were used in their assessments. thus, these undergraduates are viewed suspiciously by their educators when using online materials. not knowing how to paraphrase then cite relevant online materials causes missing learning opportunities for students. information literacy is a skill that should be considered for all technology-related courses.46 the outcomes of this course will be used to improve the education of students and place the power of learning in their hands.47 therefore, the objective of this case study is to determine the influence of information literacy practices in improving student performance in solving organizational problems, especially when technology and library resources are scarce. this longitudinal case information literacy model | abunadi 128 https://doi.org/10.6017/ital.v37i4.9750 study was conducted in two semesters: the first was conducted traditionally without the use of an information literacy intervention model, whereas in the second semester, the intervention model was introduced. finally, the performance and opinions of students for the two semesters were compared using a case study assignment and course exit survey. the information literacy intervention model was implemented by providing a series of practical tutorials at the beginning of the semester showing students how to use information from the internet. then, the students applied the information and used information literacy skills to solve weekly assessments for an enterprise-architecture (ea) course. this course is taught under the information systems program at a private university. students enrolling in the course are in their second year or higher. the information literacy assessments require students to search for reliable sources of information and cite and reference them. this forces them into the habit of critically examining sources of information, and grasping, analyzing, and using these sources to solve problems. the information literacy technology pedagogical method was followed to improve students’ knowledge of methods of learning.48 the students were educated through a series of classes on how to use the university’s databases, e-books, and internet resources to solve real-life organizational problems and to apply concepts in different situations, as shown in figure 1. the students were given ten small assessments from the moodle lms, where a concept taught in the class needed to be applied after students searched for it and learned more about it from different sources. this included looking in the correct places for reliable resources, online scholarly databases, and online videos that could be of use. then, students were taught how to critically examine resources and determine which of these could be reliable. for example, students were shown that highly cited papers were more reliable than less cited papers and that online videos from professional organizations (e.g., ibm or gartner) were more reliable than personal videos. students were also taught how to use in-text citations and how to create reference lists. in the last quarter of the semester, a case study assignment was provided with real-life problems that students were required to solve using different sources, including the internet. the performance of semester-1 students (no intervention was conducted) was compared with that of semester-2 students (information literacy intervention was conducted) taking the same course. an improvement in grades was considered a successful indicator. the comparison point was a major project that required students to solve real-life organizational problems and required greater information literacy. some of the ea concepts taught in the class required practice to apply them. for example, the as-is organizational modeling that is needed before implementing ea would be difficult to understand unless students actually conducted modeling on selected organizations. this enabled students to understand how they related to the real world. the concepts that were focused on were related to business tools in information systems (e.g., business process management and requirement elicitation) that are widely used for analysis within organizations. the theory behind these tools was explained in class; applying these theories required students to search many sources of information, including online books and research databases. students were unaware of these resources until the instructors explained their availability on the internet and in the library. the students were provided with regular information literacy sessions to improve their skills in this aspect. they were shown how to search; for instance, if they could not find a specific term, they information technology and libraries | december 2018 129 could look for synonyms. they were instructed on how to use search engines and research databases and were shown the relevant electronic journals and books that can aid in solving weekly assessments. the usage of internet multimedia is also important in education.49 the students were shown relevant youtube channels (e.g., by harvard and khan academy) and relevant massive online open courses (e.g., free courses on coursera.com and udemy.com). weekly tests required students to use these resources to solve the assessment problems. an important outcome of this intervention was an improvement in students’ abilities to use different digital resources. this was evident in semester-2 students’ usage of suitable reference lists and in-text citations, as compared to a lack of such usage by semester-1 students. an additional measure was the higher average score the students indicated in semester 2 (4.15/5), in comparison to semester 1 (3.2/5), for one of the items in the course exit survey relevant to information literacy: “illustrate responsibility for one’s own learning.” the students were continually taught that information literacy grants a power that comes with responsibility, and no incidents of plagiarism were reported during the semester in which the intervention was conducted. referencing became a habit with weekly information literacy assessments. the students’ grades in the final project were better than in the previous academic semester. the average grade for the project for semester 1 was 15.5/20, while that for semester 2 was 17/20. the difference between the grades for semester-1 and semester-2 projects was statistically significant at the level of 0.10, indicating significant differences in the students’ grades between the two semesters. the students could use digital library databases, and some were interested in using external online books. it became habitual for students to use in-text citations, and their references became diversified. some students, however, struggled at times with the limited usage of suitable references in only some paragraphs. this feedback was delivered to students so that they could address this issue in other courses. discussion and conclusion this study was conducted to investigate the most effective mode of information literacy delivery. the study focused on smaller universities because they do not have adequate library facilities and technological capabilities to provide students with sufficient information literacy competencies during course delivery. a survey was conducted to determine the most suitable form of information literacy delivery. the survey determined that moodle and face-to-face methods were both favored regarding information literacy. thus, the information literacy intervention model was developed and tested in a case study, so that students’ performance would improve. the results of this study have shown that the combination of technology and information literacy instruction is an effective method to improve student skills in using digital resources in seeking knowledge. it was found that both face-to-face learning and the use of an lms increase student performance in assessments that require information literacy. face-to-face learning is required in order to explain information literacy concepts, while the lms is used to disseminate the necessary digital resources and in creating assessment modules. thus, the arrangement of both theory and practice in information literacy resulted in better understanding and implementation in knowledge seeking and problem-solving related to information systems. the inclusion of information literacy instruction along with the use of lms for information literacy assessments within information systems courses has reduced the pressure on libraries that lack technological resources (such as pcs) and qualified staff. information literacy model | abunadi 130 https://doi.org/10.6017/ital.v37i4.9750 the results with regard to this study’s hypotheses are in agreement with those of previous studies.50 hypothesis 1, which posited that there would be a positive significant influence on information literacy disposition, is congruent with the research of churkovich and oughtred. 51 their research focused on student information literacy skill development using library facilities instead of faculty, which is a different approach than the approach followed in the present study. however, both the present study and the study of churkovich and oughtred found that using faceto-face instruction leads to improved student performance. hypothesis 2, which posited a positive impact on information literacy disposition, correlates with the research of anderson and may.52 they found that using an lms is more effective than face-to-face instruction for information literacy instruction. similar to churkovich and oughtred (and in contrast to the present study), anderson and may relied on librarians to deliver information literacy instruction online. however, anderson and may also relied on faculty staff in addition to librarians. there are two noteworthy outcomes of the first study. first, the questionnaire measurement model showed that the development of this instrument was successful and that the items and their latent variables can be used in further studies. second, the results regarding the structural model indicated that both face-to-face instruction and moodle use influenced information literacy preferences. other studies have supported these results. the results of peter et al. (2015) agree with the finding of the present study that the combination of face-to-face instruction and lms use leads to improved student performance.53 peter et al. (2015), based on psychology students, focused on the time-efficiency of the delivery of information literacy instruction; in contrast, the present study considers information literacy skill development as a progressive, long-term process. the information literacy intervention model is not only a learning medium but an interactive method of teaching that adapts to student learning patterns. the primary limitations of the study were the nature of the sample, the exclusion of some potentially relevant variables, and the simplification of the study’s findings. the sample was limited to students, professors, and people who were aware of the learning programs; it is highly possible that they were more familiar with such technological innovations than the general population. future studies could retest the hypothesis of the study in a comprehensive manner and impose more control on the respondents. the interaction between people while visiting a site is itself an activity worthy of examination, but it must be either controlled or measured for us to understand the role it plays in shaping attitudes and behaviors. future studies can apply the developed theoretical model in different settings to determine its interaction with other variables in the information systems field. a quantitative instrument can be developed based on the information literacy intervention model. alternatively, this model can be applied with qualitative interviews in future studies to develop theoretical themes based on instructors’ and students’ responses. references 1 harry m. kibirige and lisa depalo, “the internet as a source of academic research information: findings of two pilot studies,” information technology and libraries 19, no. 1 (2000): 11–15; debbie folaron, a discipline coming of age in the digital age (philadelphia: john benjamins, 2006); n. n. edzan, “tracing information literacy of computer science undergraduates: a content analysis of students’ academic exercise,” malaysian journal of library & information science 12, no. 1 (2007): 97–109. information technology and libraries | december 2018 131 2 heinz bonfadelli, “the internet and knowledge gaps,” european journal of communication 17, no. 1 (2002): 65–84, http://journals.sagepub.com/doi/abs/10.1177/0267323102017001607; kibirige and depalo, “the internet as a source of academic research information,” 11–15. 3 laurie a. henry, “searching for an answer: the critical role of new literacies while reading on the internet,” the reading teacher 59, no. 7 (2006): 614–27. 4 peyina lin, “information literacy barriers: language use and social structure,” library hi tech 28, no. 4 (2010): 548–68, https://doi.org/10.1108/07378831011096222. 5 michael r. hearn, “embedding a librarian in the classroom: an intensive information literacy model,” reference services review 33, no. 2 (2005): 219–27. 6 hui hui chen et al., “an analysis of moodle in engineering education: the tam perspective” (paper presented at teaching, assessment and learning for engineering (tale), 2012 ieee international conference on). 7 n. n. edzan, “tracing information literacy of computer science undergraduates: a content analysis of students' academic exercise,” malaysian journal of library & information science 12, no. 1 (2007): 97–109. 8 johannes peter et al., “making information literacy instruction more efficient by providing individual feedback,” studies in higher education (2015): 1–16, https://doi.org/10.1080/03075079.2015.1079607. 9 pamela alexondra jackson, “integrating information literacy into blackboard: building campus partnerships for successful student learning,” the journal of academic librarianship 33, no. 4 (2007): 454–61, https://doi.org/10.1016/j.acalib.2007.03.010. 10 manal abdulaziz abdullah, “learning style classification based on student's behavior in moodle learning management system,” transactions on machine learning and artificial intelligence 3, no. 1 (2015): 28. 11 catherine j. gray and molly montgomery, “teaching an online information literacy course: is it equivalent to face-to-face instruction?,” journal of library & information services in distance learning 8, no. 3–4 (2014): 301–9, https://doi.org/10.1080/1533290x.2014.945876. 12 william sugar, trey martindale, and frank e crawley, “one professor’s face-to-face teaching strategies while becoming an online instructor,” quarterly review of distance education 8, no. 4 (2007): 365–85. 13 stephann makri et al., “a library or just another information resource?

 kiscaden     information  technology  and  libraries  |  december  2014         51   abstract   migration  from  print  to  electronic  journals  brought  an  end  to  traditional  current  awareness  services,   which  primarily  used  print  routing.  the  emergence  of  real  simple  syndication,  or  rss  feeds,  and  email   alerting  systems  provided  users  with  alternative  services.  to  assist  users  with  adopting  these   technologies,  a  service  utilizing  aggregate  feeds  to  the  library’s  electronic  journal  content  was  created   and  made  available  through  libguides.  libraries  can  reestablish  current  awareness  services  using   existing  technologies  to  increase  awareness  and  usage  of  library-­‐provided  electronic  journal  content.   the  current  awareness  service  presented  is  an  example  of  how  libraries  can  build  basic  current   awareness  services  utilizing  freely  accessible  technologies.     current  awareness  services   library  current  awareness  services,  commonly  referred  to  as  “table  of  contents”  services,  historically   involved  the  dissemination  of  information  in  the  form  of  print  journals  or  photocopied  journal   contents  routed  to  library  users  subscribed  to  the  service.1,2  these  services  have  been  particularly   popular  among  corporate,  law,  and  hospital  libraries,  which  routinely  route  serials  to  primarily   internal  clients.  while  these  paper-­‐based  services  are  still  offered  at  some  libraries,  most  shifted  to   an  electronic  model  of  service  with  the  migration  to  electronic  journals.   as  libraries  adopted  electronic  journals,  many  paper-­‐based  current  awareness  services  transitioned   to  an  electronic  table  of  contents  service  utilizing  email  alerts  or  referred  users  to  rss  feeds  made   available  by  publishers  and  database  vendors.3  a  common  challenge  to  a  library-­‐managed  electronic   table  of  contents  service  is  the  complexity  of  managing  alerts  for  hundreds  of  electronic  journals  for   multiple  patrons.  more  often,  libraries  make  individual  users  responsible  for  subscribing  to  email   alerts  or  rss  feeds  on  their  own,  effectively  transferring  the  responsibility  of  subscribing  to,  filtering,   and  managing  incoming  information  to  the  user.   a  drawback  to  this  migration  is  that  library  users  often  don’t  possess  a  clear  understanding  of  what   tools  are  available  to  create  their  own  service.4  formerly,  journals  may  have  arrived  on  a  user’s  desk   for  perusal,  yet  now  users  are  required  to  seek  out  information  independently.  additionally,  despite   the  number  of  discovery  tools  available,  library  users  are  often  unaware  of  journals  available  in  an   electronic  format  through  their  library.5  information  management  tools  have  become  necessary  in   our  current  information  environment;  with  the  abundance  of       elizabeth  kiscaden  (elizabeth-­‐kiscaden@uiowa.edu),  former  library  director  at  waldorf  college,  is   head,  library  services,  hardin  library  for  the  health  sciences,  university  of  iowa,  iowa  city.       creating  a  current  awareness  service  using  yahoo!  pipes  and  libguides  |  kiscaden   52   information  available,  keeping  up-­‐to-­‐date  with  new  information  in  a  discipline  can  be  overwhelming.   therein  exists  an  opportunity  for  libraries—academic,  special,  and  public—to  revitalize  current   awareness  services  and  build  information  management  tools  using  aggregate  feeds.     design  and  description  of  the  service   at  waldorf  college,  the  luise  v.  hanson  library  created  a  current  awareness  service  utilizing  rss   feeds,  with  the  intent  to  assist  faculty  with  keeping  up-­‐to-­‐date  with  newly  published  content  in  the   library’s  electronic  journal  collection.  the  service,  dubbed  info  sos,  was  designed  to  overcome  two   barriers  to  patron  participation  in  feed  services:  the  chore  of  subscribing  to  and  curating  multiple   feeds  and  the  lack  of  awareness  of  feeds  and  feed  reader  technology.  info  sos  was  piloted  to  faculty   during  the  spring  of  2014  and  was  accompanied  by  an  informal  questionnaire  to  collect  feedback.   info  sos  is  built  on  rss,  or  “really  simple  syndication”  technology,  one  of  the  most  prevalent  tools  for   keeping  current  with  new  information  published  electronically.  rss  has  been  available  for  more  than   a  decade,6  and  many  users—both  patrons  and  library  professionals—are  using  this  technology.   however,  while  powerful  and  freely  accessible,  rss  feeds  have  their  limitations.  subscribing  to  and   curating  multiple  feeds  can  become  a  burden.     to  eliminate  the  chore  of  managing  multiple  feeds,  info  sos  displays  feed  aggregates  created  using   yahoo!  pipes  http://pipes.yahoo.com/pipes/).  aggregate  feeds,  or  feeds  comprising  multiple  rss   feeds,  can  be  created  using  many  tools  available  freely  online,  such  as  feed  stitch,  feed  informer,   feedburner,  and  more.  yahoo!  pipes  was  chosen  for  this  service  primarily  because  it  requires  limited   coding  knowledge,7  yet  the  software  provides  a  number  of  advanced  functions  for  sorting  and   combining  large  groups  of  feeds.  these  advanced  features  became  essential  when  building  aggregate   feeds  for  content  from  journal  aggregators.     yahoo!  pipes  requires  a  user  account  (free  of  charge)  before  constructing  pipes.  the  software   combines  and  sorts  information  using  a  visual  editor  that  resembles  virtual  plumbing,  which  is   presumably  why  the  software  is  called  pipes.  to  construct  the  aggregate  feeds  composing  info  sos,   librarians  used  the  fetch  feed  operator  to  combine  individual  rss  feeds  into  a  single  feed.  once   combined,  the  service  uses  the  sort  operator,  which  sorts  the  aggregated  content  by  date.  from  the   sort  operator,  the  content  is  connected  to  the  pipe  output,  from  which  a  single  rss  feed  is  generated.     the  strength  of  yahoo!  pipes  lies  in  the  advanced  tools  available  for  manipulating  feed  content.  for   example,  pipes  sorts  feed  content  from  database  vendors  by  the  date  it  is  published  to  the  feed,  not   the  publication  date  of  the  article.  if  desired,  aggregate  feed  creators  can  use  the  rename  and  regex   operators  to  remove  the  article  publication  date  from  the  description  field  and  use  it  to  sort  the  feed   content.  another  useful  tool  is  the  union  operator,  which  allows  creators  to  string  together  larger   bundles  of  feeds.       information  technology  and  libraries  |  december  2014   53     figure  1.  fetch  feed  and  sort  operator  in  yahoo!  pipes       figure  2.  image  of  yahoo!  pipe  using  advanced  tools     creating  a  current  awareness  service  using  yahoo!  pipes  and  libguides  |  kiscaden   54   lack  of  awareness  is  a  barrier  to  user  adoption  of  rss  feeds;  many  users  have  an  unclear   understanding  of  what  a  rss  feed  is.  if  unfamiliar  with  rss  feeds,  it  is  safe  to  assume  that  users  are   unfamiliar  with  rss  reader  technology  as  well.  at  waldorf  college,  this  was  confirmed  by  the   questionnaire  distributed  during  the  pilot  of  this  service.  of  the  twenty-­‐eight  faculty  respondents,   more  than  70  percent  had  never  used  an  rss  feed  before  using  info  sos.  it  is  safe  to  assume  that   these  faculty  would  not  have  a  subscription  to  a  feed  reader.   recognizing  the  need  for  an  interface  to  deliver  content,  librarians  used  the  libguides  software  to   display  content  from  these  aggregate  feeds.  the  software  contains  a  tool  for  adding  feed  content,  and   allows  for  the  application  of  an  institution’s  proxy  prefix  to  the  url,  creating  seamless  access  on  and   off  campus.  the  info  sos  resource  contains  tabbed  pages  designated  for  individual  fields  (biology,   psychology,  library  sciences,  etc.)  displaying  aggregate  feeds  for  journals  in  each  subject  area.  for   example,  the  physics  page  contains  aggregate  feeds  for  new  articles  published  in  the  library’s  full-­‐ text  physics  journals,  as  displayed  in  the  figure  below.       figure  3.  aggregate  physics  feeds  in  libguides   user  feedback   info  sos  remains  a  relatively  new  service  to  library  users  at  the  luise  v.  hanson  library,  but   preliminary  feedback  has  been  positive.  the  service  was  advertised  to  faculty  via  email  and     information  technology  and  libraries  |  december  2014   55   accompanied  by  a  feedback  survey  created  using  google  forms.  as  stated  previously,  librarians   received  twenty-­‐eight  responses  to  the  survey,  a  relatively  strong  response  considering  the  limited   number  of  faculty  at  the  college.   of  the  respondents,  more  than  70  percent  had  never  used  an  rss  feed  previously,  instead  using  a   variety  of  other  tools  to  stay  current  with  their  field.  of  those  other  tools,  18  percent  of  faculty   subscribed  to  table  of  contents  alerts,  27  percent  browsed  new  issues  of  print  journals,  25  percent   visited  association  websites,  and  23  percent  conducted  periodic  searches  for  information  in  the   library  databases.  it  was  of  some  concern  that  of  these  tools,  only  faculty  using  databases  and   subscribing  to  table  of  contents  alerts  would  be  connecting  with  the  library’s  electronic  journal   collection.   when  presented  with  info  sos  and  asked  whether  faculty  would  find  this  tool  useful,  more  than  70   percent  responded  that  they  would.  faculty  were  solicited  for  suggestions  for  improving  the   resource,  and  librarians  received  many  suggestions  for  expanding  the  content.  this  feedback  was   valuable  in  that  it  provided  justification  for  continuing  the  service  beyond  the  pilot  and  a  list  of   potential  subject  areas  to  begin  expanding  the  service.  the  intended  outcome  of  the  service  is  to   assist  faculty  in  keeping  current  with  literature  in  their  field  and  utilizing  the  library’s  resources  in   the  process.   limitations  and  challenges   generating  feeds  from  popular  library  databases,  such  as  ebscohost  and  proquest,  is  limited  in  that   the  publication  dates  for  articles  are  contained  in  the  description  field.  this  can  make  the  sort   operator  in  yahoo!  pipes  somewhat  inaccurate  because  it  would  be  sorting  by  the  date  they  were   published  to  the  feed,  not  by  actual  publication  date  of  the  journal  article.  if  necessary,  this  issue  can   be  corrected  using  the  rename  and  regex  operators  by  copying  the  item  description  as  the   publication  date.     an  additional  challenge  regarding  vendor-­‐created  feeds  relates  to  the  issue  of  expiring  feeds  created   from  library  databases.  a  library  profile  was  required  for  each  database,  such  as  ebscohost  or   proquest,  to  create  and  save  feeds.  this  allows  for  the  renewal  of  expiring  feeds;  the  email  account   attached  to  the  profile  receives  an  invitation  to  renew  expiring  feeds.  most  vendors  allow  for  feeds  to   be  created  at  the  database  without  a  profile,  but  those  feeds  will  automatically  expire  if  not  used   within  a  period  of  time.  the  potential  of  feeds  expiring  may  add  an  element  of  maintenance  to  the   current  awareness  service.       future  developments   yahoo!  pipes  offers  the  unique  ability  to  publish  pipes  that  others  may  share  and  “clone.”  for   libraries  interested  in  creating  aggregate  feeds  for  popular  ebscohost  journals,  the  pipes  created  for   info  sos  are  available  to  clone  at  http://pipes.yahoo.com/infosos.  a  search  of  published  pipes   available  in  yahoo!  pipes  reveals  pipes  created  by  many  public  and  academic  libraries,  all  of  which   are  available  to  clone  and  edit.  the  ability  to  share  pipes  with  other  institutions  introduces  the   possibility  of  current  awareness  services  shared  between  library  consortia  or  associations.     creating  a  current  awareness  service  using  yahoo!  pipes  and  libguides  |  kiscaden   56   as  information  becomes  more  abundant,  tools  and  services  to  manage  incoming  information  will   continue  to  be  a  corresponding  need.  creating  and  sharing  services  that  utilize  technology  common   to  libraries  presents  us  with  the  opportunity  to  collaborate  with  one  another  and  revitalize  library-­‐ engineered  current  awareness  services.  these  services  offer  a  value  that  is  twofold:  library  users   benefit  from  the  ability  to  stay  current  with  publications  in  their  field,  and  libraries  have  the   potential  of  increased  usage  of  their  purchased  content.  with  no  financial  investment,  an  aggregate   feed-­‐based  service  is  a  value  that  a  variety  of  libraries  can  implement  with  the  investment  of  only   limited  personnel  time.   references     1.    g.  mahesh  and

online library of children’s literature are described. these challenges include selecting and processing books from different countries, handling and presenting multiple languages simultaneously, and addressing cultural differences. unlike other digital libraries that present content from one or a few languages and cultures, and focus on either adult or child audiences, icdl must serve a multilingual, multicultural, multigenerational audience. the research is presented as a case study for addressing these design criteria; current solutions and plans for future work are described. t he internet is a multilingual, multicultural, multigenerational environment. while once the domain of english-speaking, western, adult males, the demographics of the internet have changed remarkably over the last decade. as of march 2004, english was the native language of only 35 percent of the total world online population. as of march 2004, asia, europe, and north america each make up roughly 30 percent of internet usage worldwide.1 in the united states, women and men now use the internet in approximately equal numbers, and children and teenagers use the internet more than any other age group.2 creators of online digital libraries have recognized the benefit of making their content available to users around the world, not only for the obvious benefits of broader dissemination of information and cultural awareness, but also as tools for empowerment and strengthening community.3 creating digital libraries for children has also become a popular research topic as more children access the internet.4 the international children’s digital library (icdl) project seeks to combine these areas of research to address the needs of both international and intergenerational users.5 ■ background and related work creating international software is a complex process involving two steps: internationalization, where the core functionality of the software is separated from localized interface details, and localization, where the interface is customized for a particular audience.6 the localization step is not simply a matter of language translation, but involves technical, national, and cultural aspects of the software.7 technical details such as different operating systems, fonts, and file formats must be accommodated. national differences in language, punctuation, number formats, and text direction must be handled properly. finally, and perhaps most challenging, cultural differences must be addressed. hofstede defines culture as “the collective mental programming of the mind which distinguishes the members of one group or category of people from another.”8 these groups might be defined by national, regional, ethnic, religious, gender, generation, social class, or occupation differences. by age ten, most children have learned the value system of their culture, and it is very difficult to change. hofstede breaks culture into four components: values, rituals, heroes, and symbols. these components manifest themselves everywhere in software interfaces, from acceptable iconic representations of people, animals, and religious symbols to suitable colors, phrases, jokes, and scientific theories.9 however, as hoft notes, culture is like an iceberg: only 10 percent of the characteristics of a culture are visible on the surface.10 the rest are subjective, unspoken, and unconscious. it is only by evaluating an interface with users from the target culture that designers can understand if their software is acceptable.11 developers of online digital libraries have had to contend with international audiences for many years, and the marc and oclc systems have reflected this concern by including capabilities for transliteration and diacritical characters (accents) in various languages.12 however, it is only more recently, with the development of international character-set standards and web browsers that recognize these standards, that truly international digital libraries have emerged. greenstone, an the international children’s digital library: a case study in designing for a multilingual, multicultural,

of firstsearch, a web-based bibliographic and full-text retrieval service, to accommodate users with different software, languages, and disabilities.14 researchers at virginia tech redesigned citidel, an online collection of computer-science technical reports, to create an online community that allows users to translate their interface into different languages.15 researchers have also realized that beyond accessibility, digital libraries have enormous potential for empowerment and building community, especially in developing countries. witten et al. and downie describe the importance of community involvement when creating a digital library for a particular culture, both to empower users and to make sure the culture is accurately reflected.16 even more than accurately reflecting a culture, a digital library also needs to be understood by the culture. duncker notes that a digital-library interface metaphor based on a traditional physical library was incomprehensible to the maori culture in new zealand, who are not familiar with the conventions of western libraries.17 in addition to international libraries, a number of researchers have focused on creating digital libraries for children. recognizing that children have difficulty with spelling, reading, and typing, as well as traditional categorization methods such as the dewey decimal system, a number of researchers have created more child-friendly digital libraries.18 pejtersen created the bookhouse interface with a metaphor of rooms in a house to support different types of searching.19 külper et al. designed the bücherschatz interface for children who are eight to ten years old using a treasure-hunt metaphor.20 druin et al. designed the querykids interface for young children to find information about animals.21 theng et al. used the greenstone software to create an environment for older children to write and share stories.22 the icdl project seeks to build on and combine research in both international and children’s digital libraries. as a result, icdl is more ambitious than other digital library projects in a number of respects. first, it is designed for a broader audience. while the digital libraries already described target one or a few cultures or languages, icdl’s audience includes potentially every culture and language in the world. second, the content is not localized. part of the library’s goal is to expose users to books from different cultures, so it would be counterproductive to present books only in a user’s native language. as a result, the interface not only supports multiple languages and cultures, but it also supports them simultaneously, frequently on the same screen. third, icdl’s audience not only includes a broad group of adults from around the world, but also children from three to thirteen years of age. to address these challenges, a multidisciplinary, multilingual, multicultural, and multigenerational team was created, and the development was divided into several stages. in the first stage, completed in november 2002, a java-based, english-only version of the library was created that addressed the searching and reading needs of children. in the second stage, completed in may 2003, an html version of the software was developed that addressed the needs of users with minimal technology. in the third stage, completed in may 2004, the metadata for the books in the library were translated into their native languages, allowing users to view these metadata in the language of their choice. the final stage, currently in progress, involves translating the interface to different languages and adjusting some of the visual design of the interface according to the cultural norms of the associated language being presented. in this paper, the research is presented as a case study, describing the solutions implemented to address some of these challenges and plans for addressing ongoing ones. ■ icdl project description the icdl project was initiated in 2002 by the university of maryland and the internet archive with funding from the national science foundation (nsf) and the institute for museum and library services (imls). today, the projects continues at the university of maryland. the goals of the project include: ■ creating a collection of ten thousand children’s books in one hundred languages; ■ collaborating with children as design partners to develop new interfaces for searching, browsing, reading, and sharing books in the library; and ■ evaluating the impact of access to multicultural materials on children, schools, and libraries. the project has two main audiences: children three to thirteen years of age and the adults who work with them, as well as international scholars who study children’s literature. the project draws together a multidisciplinary team of researchers from computer science, library science, education, and art backgrounds. the research team is also multigenerational—team members include children seven to eleven years of age, who work with the adult members of the team twice a week during the school year and for two weeks during the summer to help design and evaluate software. using the methods of cooperative inquiry, including brainstorming, lowtech prototyping, and observational note taking, the team has researched, designed, and built the library’s category structure, collection goals, and searching and reading interfaces.23 the international children’s digital library | hutchinson, rose, bederson, weeks, and druin 5 6 information technology and libraries | march 2005 the research team is also multilingual and multicultural. adult team members are native or fluent speakers of a number of languages besides english, and are working with school children and their teachers and librarians in the united states, new zealand, honduras, and germany to study how different cultures use both physical and digital libraries. the team is also working with children and their teachers in the united states, hungary, and argentina to understand how children who speak different languages can communicate and learn about each other’s cultures through sharing books. finally, an advisory board of librarians from around the world advises the team on curatorial and cultural issues, and numerous volunteers translate book and web-site information. ■ icdl interface description icdl has four search tools for accessing the current collection of approximately five hundred books in thirty languages: simple, advanced, location, and keyword. all are implemented with java servlet technology, use only html and javascript on the client side, and can run on a 56k modem. these interfaces were created during the first two development phases. the team visited physical libraries to observe children looking for books, developed a category hierarchy of kid-friendly terms based on these findings, and designed different tools for reading books.24 using the simple interface (figure 1), users can search for books using colorful buttons representing the most popular search categories. the advanced interface (figure 2), allows users to search for books in a compact, text-link-based interface that contains the entire librarycategory hierarchy. by selecting the location interface (figure 3), users can search for books by spinning a globe to select a continent. finally, with the keyword interface, users search for books by typing in a keyword. younger children seem to prefer the simplicity and fun of the location interface, while older children enjoy browsing the kid-friendly categories, such as colors, feelings, and shapes.25 all of these methods search the library for books with matching metadata. users can then read the book using a variety of book readers, including standard html pages and more elaborate java-based tools developed by the icdl team that present book pages in comic or spiral layouts (figures 4–6). in addition to the public interface, icdl also includes a private web site that was developed for book contributors to enter bibliographic metadata about the books they provide to the library (figures 7 and 8). using the metadata interface, contributors can enter information about their books in the native language of the book, and optionally translate or transliterate this information into english or latin-based characters. the design of icdl is driven by its audience, which includes users, contributors, and volunteers of all ages from around the world—more than six hundred thousand unique visitors from more than two hundred countries (at last count). as a result, books written in many different languages for users of different ages and cultural backgrounds must be collected, processed, stored, and presented. the rest of this paper will describe some of the challenges encountered and that are still being encountered in the development process, including selecting and processing a more diverse collection of books, handling different character sets and fonts, and addressing differences in cultural, religious, social, and political interpretation. figure 2. icdl advanced interface figure 1. icdl simple interface ■ book selection and processing the first challenge in the icdl project is obtaining and managing content. collecting books from around the world is a challenge because national libraries, publishers, and creators (authors and illustrators) all have different rules regarding copyrights. the goal is to identify and obtain award-winning children’s books from around the world, for example, books on the white ravens list, which are also made available to icdl users (www. icdlbooks.org/servlet/whiteravens).26 however, unsolicited books are received, frequently in languages the team cannot read. as a result, members of the advisory board and various children’s literature organizations in different countries are relied on to review these books. these groups help determine whether books are relevant and acceptable in the culture they are from, and whether they are appropriate for the three-to-thirteen age group. these groups are eager to help; including them in the process is an effective way to build the project and the community surrounding it. in addition to collecting and scanning books, bibliographical metadata in the native language of the book (title, creator[s], publisher, abstract) are also collected via the web-based metadata form filled out by the book contributors. it was decided to base the icdl metadata specification on the dublin core because of its international background, ability to be understood by nonspecialists, and the possibilities to extend its basic elements to meet icdl’s specific needs (see www.icdlbooks.org/ metadata/specification for more details).27 contributors who provide metadata have the option of translating them to english; they also can transliterate them to latin characters, if necessary. regardless of what language or figure 5. icdl comic book reader figure 3. icdl location interface figure 4. icdl standard book reader figure 6. icdl spiral book reader the international children’s digital library | hutchinson, rose, bederson, weeks, and druin 7 8 information technology and libraries | march 2005 languages they provide, they are asked to provide information that they create themselves, such as the abstract, in a format that is easily understandable by children. simple, short sentences make the information easy for children to read, and easier to translate to other languages. the metadata provided allow the team to catalog the books for browsing according to the various categories and to index the books for keyword searching. even though translation to english is optional, the englishspeaking metadata team needs the metadata in english in order to catalog the books. since many contributors do not have the time or ability to provide all of this information, volunteers who speak different languages are relied on to check the metadata that get submitted, and translate or transliterate them as necessary. this method allows information to be collected from contributors without overwhelming them, and also helps build and maintain the volunteer community. ■ handling different character sets the metadata form allows contributors to provide information from the comfort of an operating system and keyboard in their native language, but this flexibility requires software that can handle many different character sets. for example, english uses a latin character set; russian uses a cyrillic character set; and an arabic character set is used for persian/farsi. fortunately, there exists a single character set called unicode, an international, cross-platform standard that contains a unique encoding for nearly every character in every language.28 unfortunately, not all software supports unicode as yet. in the first stage of implementation in icdl, metadata information was collected only in english, so unicode compliance was not a problem. however, in the next phase of development, which included collecting and presenting metadata in the native language of all of the books, the software had to be adjusted to use unicode because icdl supports potentially every language in the world. the open-source mysql database, recently upgraded to allow storage of unicode data, was already in use for storing metadata. icdl’s web applications run on apache http and tomcat web servers, both of which are freely available and unicode-compliant. however, both the web site and the database had to be internationalized and localized to separate the template for metadata presentation from the content in different languages. a unicode-compliant database driver was necessary for passing information between the database and the web site. both the public and metadata web-site applications are written using freely available java servlet technology. the java language is unicode-compliant, but some adjustments had to be made to icdl’s servlet code to force it to handle data using unicode. to allow users to conduct keyword searches for books in the public interface, apache’s freely available lucene search engine is used to create indices of book metadata, which can then be searched. lucene is unicode-compliant, but a separate index for each language had to be created, requiring users to select a search language. this requirement was necessary for two reasons: (1) to avoid confusion over the same words with different meanings (bra means good in swedish); and (2) different languages have different rules for stopwords to ignore (the, of, a in english), truncation of similar words (cats has the same root as cat in english), and separation of characters (chinese does not put white space between symbols). lucene has text analyzers for a variety of languages that support these different conventions. for languages that figure 8. icdl metadata interface with japanese metadata figure 7. icdl metadata interface with spanish metadata lucene does not support, icdl volunteers translated english stopwords, and simple text analyzers were created by the team. finally, html headers created by the java servlets had to be modified to indicate that the content being delivered to users was in unicode. most current browsers and operating systems recognize and handle web pages properly delivered in unicode. for those that do not, help pages were created that explain how to configure common browsers to use unicode, and how to upgrade older browsers that do not support unicode. by making the icdl systems fully unicode-compliant, contributors from all over the world can enter metadata about books in an easily accessible html form using their native languages, and the characters are properly transmitted and stored in the icdl database. volunteers can then use the same form to translate or transliterate the metadata as necessary. finally, this information can be presented to our users when they look at books. for example the book where’s the bear? (harris, 1997) is written in six different languages.29 the original metadata came in english, but icdl volunteers translated them to italian, japanese, french, spanish, and german. users looking at the preview page for this book in the library have the opportunity to change the display language of the book to any one of these languages using a pull-down menu (figures 9 and 10). currently, only the book metadata language can be changed, but in the next stage of development, all of the surrounding interface text (navigation, labels) will be translated to different languages as well. the plan for doing this is to take a similar approach to the citidel and greenstone projects by creating a web site where volunteers can translate words and phrases from the icdl interface into their native language.30 like the creators of citidel, the team believes that machine-based translation would not provide good enough results. unfortunately, the resources do not exist for the team to do the translating themselves. encouraging volunteers to translate the site will help enlarge and enrich the icdl community. for languages that do not receive volunteer translation, translation services are an affordable alternative. ■ character-set complications several issues have arisen as a result of collecting multilingual metadata in many character sets. first, different countries use different formats for dates and times, so contributors are allowed to specify the calendar used when they enter date information (muslim or julian). second, not only do different countries use different formats for numbers, the numbers themselves are also different. for example, the arabic numbers for 1, 2, 3 are even though java is unicode-compliant, it treats numbers as latin characters, necessitating the storing of latin versions of any non-latin numbers used internally by the software for calculations, such as bookpage count. a third issue is that some of the metadata, such as author and illustrator names, need to be transliterated so their values can be displayed when the metadata are shown in a latin-based language. ideally, the transliteration standards used for a language need to be consistent so that the same values are always transliterated the same way. unfortunately, the team has found no practical way to enforce this, except to state the standard to be used in icdl metadata specification. when different standards are used, it makes comparison of equal items much more difficult. for example, the same persian/farsi creator has been figure 10. where’s the bear? in japanese figure 9. where’s the bear? in english the international children’s digital library | hutchinson, rose, bederson, weeks, and druin 9 10 information technology and libraries | march 2005 transliterated as both “hormoz riyaahi” and “hormoz riahi.” it cannot be assumed that a person is the same just because the name is the same (john smith), and when a name is in a character set that the team cannot understand, this problem becomes more challenging. finally, there was the question of how to handle differences in character-set length and direction in the interface. different languages use different numbers of characters to present the same text. icdl screens had to be designed in such a way that the metadata in languages with longer or shorter representations than the english version would still fit. the team anticipates having to make additional interface changes to accommodate longer labels and navigational aids when the remainder of the interface is translated. the fact also had to be considered that, while most languages are read left to right, a few (arabic and hebrew) are read right to left. as a result, screens were designed so that book metadata were reasonably presented in either direction. currently, only the text is displayed right to left, but eventually the goal is to mirror the entire interface to be oriented right to left when content is shown in right-to-left languages. for the problem of how to handle the arrows for turning pages in right-to-left languages—since these arrows could be interpreted as either “previous” and “next” or “left” and “right”—“previous” and “next” were chosen for consistency, so they work the same way in leftto-right books and right-to-left books. ■ font complications while most current browsers and operating systems recognize unicode characters, whether or not the characters are displayed properly depends on whether users have appropriate fonts installed on their computers. for instance, a user looking at where’s the bear? and choosing to display the metadata in japanese will see the japanese metadata only if the computer has a font installed that includes japanese characters. otherwise, depending on the browser and operating system, he may see question marks, square boxes, or nothing at all instead of the japanese characters. the good news is that many users will never face this problem. the interface for icdl is presented in english (until it is translated to other languages). since most operating systems come with fonts that can display english characters, the team has metadata in english (always presented first by default) for nearly all the books. users who choose to display book metadata in another language are likely to do so because they actually can read that language, and therefore are likely to have fonts installed for displaying that language. furthermore, many commonly used software packages, such as microsoft office, come with fonts for many languages. as a result, many users will have fonts installed for more languages than just those required for the native language of their operating system. of course, fonts will still be a problem for other users, such as those with new computers that have not yet been configured with different fonts or those using a public machine at a library. these users will need to install fonts so they can view book metadata, and eventually the entire interface, in other languages. to assist these users, help pages have been created to assist users with the process of installing a font on various operating systems. ■ issues of interpretation while technical issues have been a major challenge for icdl, a number of nontechnical issues relating to interpretation have also been encountered. first, until the interface has been translated into different languages, visual icons are crucial for communicating information to young children who cannot read, and to users who do not speak english. however, certain pictorial representations may not be understood by all cultures, or worse, may offend some cultures. for example, one icon showing a boy sticking out his tongue had to be redesigned when it was learned this was offensive in the chinese culture. the team has also redesigned other icons, such as those using stars as the rating system for popular books. the original icons used five-sided stars, which are religiously significant, so they were changed to more neutral sevenor eight-sided stars. as the team continues to internationalize the interface, there will likely be a need to change other icons that are difficult to represent in a culturally neutral way when the interface is displayed in different languages. for instance, it is a real challenge to create icons for categories such as mythology or super heroes, since the symbols and stories for these concepts differ by culture. icons for such categories as funny, happy, and sad are also complicated because certain common american facial and hand representations have different, sometimes offensive, meanings in different cultures. what is considered funny in one culture (a clown) may not be understood well by another culture. different versions of such icons may have to be created, depending on the language and cultural preferences of users. the team relies on its multicultural members, volunteers, and advisory board to highlight these concerns. religious, social, and political problems of interpretation have also been encountered. icdl’s collection develops unevenly as relationships are built with various publishers and libraries. as a result, there are currently many arabic books and only a few hebrew books; this has generated multiple e-mails from users concerned that icdl is taking a political stance on the arab-israeli conflict. to address this concern, the team is currently working to develop a more balanced collection. many books published in hong kong are received from contributors in either hong kong or china who want their own country to be credited with publication. to address this concern, it was decided to credit the publication country as “hong kong/china” to avoid offending either party. finally, some books have been received with potentially objectionable content. some of these are historical books involving presentation of content that is now considered derogatory. some include subject matter that may be deemed appropriate by some cultures but not by others. some include information that may be too sophisticated for children three to thirteen years of age in any culture. while careful not to include books that are inappropriate for children in this age group, the team does not want to censor books whose content is subjectively offensive. instead, such contributors are consulted to make sure they were aware of icdl collection-development guidelines. if they believe that a book is historically or culturally appropriate, the book is included. a statement is also provided at the bottom of all the book pages indicating that the books in the library come from diverse cultures and historical periods and may not be appropriate for all users of the library. ■ conclusions and lessons learned designing a digital library for an international, intergenerational audience is a challenging process, but it is hugely rewarding. the team is continually amazed with feedback from users all over the world expressing thanks that books are made available from their countries, from teachers who use the library as a resource for lesson planning, from parents who have discovered a new way to read with their children, and from children who are thrilled to discover new favorite books that they cannot get in their local library. thus, the first recommendation the team can make based on experience is that creating international digital-library resources for children is a rich and rewarding area of research that others should continue to explore. a second important lesson learned is that an international, intergenerational team is an absolute necessity. simply having users and testers from other countries is not enough; their input is valuable, but it comes too late in the design process to influence major design changes. team members from different cultural backgrounds offer perspectives that an american-only team simply would not think to consider. similarly, team members who are children understand how children like to look for and read books, and what interface tools are difficult or easy, and fun or not fun. enthusiastic advisors and volunteers are also a crucial resource. the icdl team does not have the time, money, or resources to address all of the issues that surface, and advisors and volunteers are key resources in the development process. bringing together as diverse a team as possible is highly recommended. the goals of educational enrichment and international understanding in an international library make it an attractive resource for people to want to help, so assembling such a team is not as difficult as it sounds. beyond the human resources, the technical resources involved in making icdl an international environment necessitate the examination and adjustment of software and interfaces at every level. unlike many digital libraries that only focus on one or a few languages, icdl must be simultaneously multilingual, multicultural, and multigenerational. as a result, a third lesson is that freely available and open-source technologies are now available for making the necessary infrastructure meet these criteria. with varying degrees of complexity, the team was able to get all the pieces to work together properly. the more difficult challenge, unfortunately, falls on icdl’s users, who may need to install new fonts to view metadata in different languages. however, as computer and browser technologies advance to reflect more global applications, this problem is expected to lessen and eventually disappear. having technical staff capable of searching for and integrating open-source tools with international support to handle these technical issues is highly recommended, as well as usability staff versed in the nuances of different operating systems and browsers. finally, the more subjective issue of cultural interpretation has proven to be the most interesting challenge. it is one that will likely not disappear as icdl’s collection grows and the next stage of development is embarked on for translating the interface to support other languages and cultures. the fourth lesson learned is that culture pervades every aspect of both the visual design and the content of the interface, and that it is necessary to examine one’s own biased cultural assumptions to ensure respect of others. however, with the enthusiasm that continues to be seen in the icdl team members, advisors, volunteers, and users, future design challenges will be able to be addressed with their help. the final recommendation is to actively seek feedback from team members, volunteers, and users from different backgrounds about the cultural appropriateness of all aspects of your software. it may not be possible to address all cultures in your audience right away, but it is important to have a framework in place so that these issues are addressed eventually. the international children’s digital library | hutchinson, rose, bederson, weeks, and druin 11 12 information technology and libraries | march 2005 ■ acknowledgments icdl is a

attempt to develop geographic information systems (gis) technology into an analytical tool for examining the relationships between the height of the bookshelves and the behavior of library readers in utilizing books within a library. the tool would contain a database to store book-use information and some gis maps to represent bookshelves. upon analyzing the data stored in the database, differen t frequencies of book use across bookshelf layers are displayed on the maps. the tool would provide a wonderful means of visualization through which analysts can quickly realize the spatial distribution of books used in a library. this article reveals that readers tend to pull books out of the bookshelf layers that are easily reachable by human eyes and hands, and thus opens some issues for librarians to reconsider the management of library collections. several years ago, when working as a library assistant reshelving books in a university librar y, the author noted that the majority of books used inside the library were from the mid-range laye rs of bookshelves. that is, b y proportion , few books pulled out by library readers were from the top or bottom layers. books on the layers

ers' selectiv eness on library books by deliberately arranging collections at design ated heights on book sh elves. a research study was designed to develop geographical information systems (gis) into an analytical tool to examine former casual observations by the author. the study was conducted in the mackimmie library at the university of calgary. thi s paper highlights th e results of the study that aimed at assessing th e behavior of library readers in pulling out books from bookshelves . thes e book s, when not checked out, are categoriz ed as "pickup books" becau se they are usually discarded inside a library after use and then picked up by library assistants for reshelving. like many other libraries , the mackimmie library does not encourage reasd ers to reshelve books th emse lves. arcview, a gis software, was selected to develop th e tool for this study because gis ha s the functions of dynamicall y analyzing and di splayin g spatial data. the research on library readers pullin g out books involv es the measur emen ts of bookshelf heights, and thu s deals with spatial coordinates. with the capability of presenting book shelves in different views on map s, gis is able to provide readers with an easy und erstanding of the anal ytical results in visual forms, which make any textu al description s wordy . at the same time, some gis products are available now in most academic libraries, thus giving develop ers convenient access to use. hypothesis when library users decide to check books out of a library, the se books are what the y think of as useful. peopl e are usually hesitant to carry home books that are of little or uncertain use, not only because of the limit on the numb er of check-out books , but also bec ause of the physical work required for carrying them. moreover, some items, such as periodicals and multimedia materials, are either designated as "refe rence only" or have a very short loan period . it is reasonable to beli eve that user s carefully select what they want from library collections and keep these book s for handy use outside the library. by contrast , in-library book use repre sents a different category of library readers' behavior . there are two general categories of in-library book us e: readers bringin g their own books into a library for use, and readers pulling out book s from bookshelves inside a librar y. the former is commonly seen when students study textbook s for examinations (not the topic of this study), whil e the latter is a little more complex. 1 as library users approach bookshelves to extract book s, th ey may or may not hav e a definit e target. when coming with call numb ers, peopl e will deliberately draw the books they want for reading, photoc opyi ng , or referencing. ho wever, there are time s when user s on ly wander in bookshelf aisles of desired collections, uncertain about singling out specific books . th ey may simply shelf-shop to randomly select whatever is interesting to them, or they may locate a subject of need and go to the storage position(s) to look for whatever books are there. no matter what these readers' intention s are, they roam among collections, pick book s for quick u se, and leave them inside the library after use, although some materials may also be checked out. because of such arbitrary selections from library collections , physical con venie nce sometimes influence s library users in takin g books from booksh elves-they ma y look around for books on bookshelf layers that are at a reach able height. the standard library bookshelf is hi gher than the average person's height and is structured to have five to eigh t layers. in aca demic libraries, "wood shelving is available in three heights: 82 in. (2050 mm), with a bottom shelf and six ad justabl e shelves; 60 in. (1500 mm), with a b ottom shelf and four adjustable she lves; and 42 in. (1050 mm), with a bottom shelf and two adjustable shel ves ." 2 for regular collections in mo st academic libraries, bookshelve s are usually about eightytwo inches high and hav e seven layers. books on the top lay er are out of reach for many reader s, requiring them to use a ladder to draw a book from it. many users are hesitant to use ladders. even worse, a reader will have to bend over or squ at down to view the contents of books on the bottom layer of a bookshelf . hence , the hypothe sis is that books used inside a library are primarily distribut ed among the mid-ranged layers of bookshelves. specifically, if a bookshelf ha s seven lay ers, books placed on layers two through six are most frequently consulted. this is the subject of this research paper . background a considerable number of studies have investigated the utilization of books that are checked out of a library. an esti mate made in 1967 pointed out that over seven hundred research results pertained to this topic. ' how ever, the situation of books used inside a library has not been given enough attention. one of the reasons for this seeming neglect comes from the belief that the records of library book s in circulation provide similar info rma tion as those of books used within libraries." thi s misunderstanding wa s lately criticized by other researchers who discov ere d the differences in use behavior

research ers hav e now recog ni zed that correlations between the two sets of data are n ot as strong as they seemed to be. such reco gnition, unfortunately, ha s not resulted in mor e consequ ent

po ssible and easier than ever before. on e exampl e of the technologi es is the radio freque ncy identification (rfid) tag system that ha s been adopted b y some public and acade mic librar ies recently.8 thi s system stores a tag in each librar y item with the item's biblio gra phic information, and uses an antenna to keep tr ack of th e tag. by automatically communicating with dat a stored in the tags, the system can collect dat a on all librar y collections in a timel y manner and export them into pred esigned d atabases for easy man ag ement. data an a lys is and pres enta tion

visuali za tion through gis produ cts has been very good, which giv es them advantages over other analytic al, stati stical, or repor tin g produ cts. combining rfid and gis into one system would seem to be th e perfect solution-the former can effective ly carry out dat a collection and th e latter can efficiently perfo rm data analysis and presentation. h ow ever, while gis products h ave been u sed in libraries in the unit ed states for more th an a dec ade, mo st academic libraries are hesitant to invest in rfid because of its high costs . gis technology alone, however , can still provide sufficient functions to be dev eloped into such an analytical tool. up to n ow, tho se librarie s that have provid ed gis serv ices only use the software that assists in the utilization of geospatial data and map186 information technology and libraries i december 2004 ping te chnologie s for users .9 gis is not expl oited enou gh to aid the manage ment of librari es them selves and the res earch

with library users, which can be another rese arch project. each book shelf laye r wa s recorded with and signified by two call numbers: the start and end numbers of books. for example, the call numbers "bf1999 .k54" to "bh21 .b35 1965," representing books stored on a particular layer, were record ed to identify that layer . because book shifting can happen from time to time, such recording of start and end call numbers for individual book shelf layers only reflects the condition s when this research wa s undertaken and may need updates whenever changes occur. data manipulation and visualization using a bookshelf lay er as the recording unit is essenti al for the analysi s of the relationship between book use and bookshelf height. each book used can be classifi ed to fit in one unit according to the call num ber of the book. therefore , building a databas e with a table for lay ers will be an important part in the development of such an analytic al tool. the layers tabl e includes a data field as an identifi e r to stand for the sequenc e of e ach layer-1 for the top layer, 2 for th e next layer down , and so on , in addition to storing the start and end call numbers of books for each lay er. if more than one bookshelf in th e library has seven layers, layer identifiers will it erate from booksh elf to bookshelf . therefore, this tabl e will also need an identifier for each individual book shelf with which lay ers are associated. the dat abase will also contain such information as bookshelf ranges, bookshelf racks, and books , all of which are individual database tables that are joined with each other by relational keys. among them, the ranges table is simply characterized by its id entifier, and is designed to repre se nt two rack s of book shelves that stand back to back. the bookshelves table is identified by the call numbers of the start and end books stor ed across individual bookshelves rather than on individual layers. furthermore, th e books table is primarily filled with the data of individual book call numbers as well as book pickup time s and book discard locations . gis h as lim ited ability for orga nizing da

per layer, at bookshelf level, across multipl e bookshelf ranges. this demonstration provides a better visualization in the gis di splay so that an ov erall view of the height distributions of book usage over certain collection areas can be presented (see figures 2 and 3). to achi eve such visualization, data must be compared in order to get information about which layer of a bookshelf 188 information technology and libraries i december 2004 contains the most frequently used books and which holds thos e that are rarely visit ed . this demonstration indicates that any alternative selection of analytical-display units can be easily performed by making modifications on the query that works on aggregating data . technically, data visualization can be presented by using an y gis software, although arcview is used here because it has been availabl e in the systems of many academic libraries. bookshelf ranges in mackimmie library 's fifth floor were drawn into map features . in order to show them with a three-dim ensional view, each of the seven layers was given a sequential number as its height value , and all book shelves were treated as having the same height. these height values are tre a ted as the z values in any three-dimensional analysis. then, by associating the numbers of books from the database with the heights of layers on the map, arcview is able to sketch the hei ght distributions of inlibrary book us e in new perspectives, dramatically improving the understanding of book use. in order to implement the visualiza tion of all layers across a bookshelf range, lay ers were drawn as map features (see figure 1). layer heights and widths are in appropriat e proportion . (individual book s on each layer are for demonstration only, and thus are not in the exact shape and number.) figure 1 shows how a bookshelf rack has been presented as a gis map, which is a totally new idea in the applications of gis visualization . the databas e and visualization mechanism constitute what is referred to in this paper as the analytical tool. one will find that th e development is relatively easy and the tool is incredibly simple. however, it is a dynamic device. if expanded into other parts of the library collections, this tool will become an integrated system that is able to assi st in the management of library book use and reproduced with permission of the copyright owner. further reproduction prohibited without permission. ••••m•====

routine operation of the system is to regularly update the database (by using rfid if possible, or by connecting to circulation databases) and analyze and display the updates on the gis maps. the analyst has the flexibility of easily flipping the displays of the three-dimensional views by 360 degrees, zooming in on specific features on the maps, as well as making any feature transparent for even more sophisticated viewing. gis's magic functionality makes the tool graphically elaborate. findings and conclusions the results have been visually exhibited on the gis maps. for demonstration purposes, figures 1 through 3 display only one portion of collections on the fifth floor. nonetheless, this small part of the illustrati ons has been able to show clear patterns of the usage pattern of library books. figure 1 is the frontal view of a bookshelf rack that uses different levels of color density to present varied numbers of books used by readers on different layers. shown as an example, it is clear from this picture that all top and bottom layers either are white or have lighter colors, because book-use numbers are very low on these layers, while colors on layers 2 to 6 are darker. by extending the one-rack view to reveal several bookshelf ranges on the fifth floor, figures 2 and 3 present different perspectives. the height of each bookshelf in figure 2 represents the layer of the bookshelf, from which the most frequently browsed books are counted. please note that the height of the nearest bookshelf range is at its highest (the top layer) for easy visual comparison. this grap h shows that th e majority of bookshelves here have a height suitable for regular readers to browse and retrieve books. a clear using gis to measure in-library book-use behavior i xia 189 reproduced with permission of the copyright owner. further reproduction prohibited without permission. pattern has therefore been revealed: most of the books used are on easily reached layers. in contrast to figure 2, figure 3 shows the least-used layer for each bookshelf. it is obvious that the heights are either the highest or the lowest, indicating the infrequent number of visits to layers 1 (the top) and 7 (the bo ttom). hence, a strong correlation between the height of book locations on a bookshelf and the tendency of library users to pull out what they are interested in is visually portrayed. this occurrence has confirmed the hypothesis that books on the top and bottom layers of a bookshelf, by reason of their inconvenienc e to users, receive less attention than books on other layers. people seem to favor the items that are stored at a reachable distance when they glance through library collections without a definite destination. the findings suggest that a library should conduct more surveys to see which books are truly useful for its users. the most useful items should be arranged on bookshelves with a height suitable for averagesized people. many public libraries have already noticed the importance of regulating shelf layers for the convenience of readers, especially for elderly and young readers. however, academic libraries have not yet paid enough attention to this issue. an alternate solution is to adjust the height of bookshelves in a library. similar efforts have already been made by some libraries in an attempt to increase the space of the top and bottom bookshelf layers and place specific collections such as oversized books on them. for example , the mars hill college library in north carolina has purposely arranged little-used items on top layers. 15 nonetheless, such a structure is merely appropriate for certain typ es of library collections. to adopt a general rule for designing bookshelves for all collections in a library, one possibility is to take the entire library space into consideration at the planning stage of library architecture and lower the heights of all bookshelves wherever applicable . no matter what strategies a library takes to improve the usability of its books, the findings of this study make it obvious that librarians have the potential of guiding or directing the choices library users make from library collections by purposely positioning selected books. the strategy is similar to what grocery stores have successfully managed as the aisle display for business promotions. although such a conclusion could bring controversy to library management, the research has at least introduced an issue for librarians to take into account when they make decisions on the management of library collections. this study is an experiment in data manipulation and visual demonstration. its results are only suggestive, due to the sample size and the lack of distinction between random extraction and deliberate selection of books for use within a library. its value can be accentuated as soon as th e analytical system gets expanded into the entire collection of a library and data accumulate over a period of time. supplementary research on this topic could also embrace ethnographic investigations among library users to increase the library profession's understanding of usage patterns of in-library books. this study was specifically for the purpose of measuring the behavior of library readers using in-library books with regard to bookshelf heights and spatial distributions of books. however, any library that is interested in investing in an analytical tool for its daily operations can make proper, yet simple, modifications on the tool without going to a great deal of expense. the ideas are attractive and practical. future work could concentrate on integrating rfid's power of collecting and communicating data on the use of inlibrary books with gis's strength of 190 information

retyping or cutting and pasting the heading(s) into the cataloging interface along with any diacritics, and potentially correcting formatting and subfield coding. if authority control is available in the interface, some of these tasks may be automated or partially automated. a cataloger with a reasonable knowledge of faceted application of subject terminology (fast)1,2 or even library of congress subject headings (lcsh)3 can quickly get to the proper heading but usually needs to confirm the final details—was it plural? am i thinking of an alternate form? is it inverted? etc. this often requires consulting the full authority file interface. assignfast is a web service that consolidates the entire second phase of the manual process of subject assignment for fast subjects into a single step based on autosuggest technology. background faceted application of subject terminology (fast) subject headings were derived from the library of congress subject headings (lcsh) with the goal of making the schema easier to understand, control, apply, and use while maintaining the rich vocabula ry of the source. the intent was to develop a simplified subject heading schema that could be assigned and used by nonprofessional cataloger or indexers. faceting makes the task of subject assignment easier. without the complex rules for combining the separate subdivisions to form an lcsh heading, only the selection of the proper heading is necessary. the now-familiar autosuggest4,5 technology is used in web search and other text entry applications to help the user enter data by displaying and allowing the selection of the desired text before typing is complete. this helps with error correction, spelling, and identification of commonly used terminology. prior discussions of autosuggest functionality in library systems have focused primarily on discovery rather than on cataloging.6-11 rick bennett (rick_bennett@oclc.org) is a consulting software engineer in oclc research

information technology and libraries | march 2014 35 the literature often uses synonyms for autosuggest, such as autocomplete or type-ahead. since assignfast can lead to terms that are not being typed , autosuggest seems most appropriate and will be used here. the assignfast web service combines the simplified subject choice capabilities of f ast with the text selection features of autosuggest technology to create an in -interface subject assignment tool. much of a full featured search interface for the fast authorities, such as searchfast ,12 can be integrated into the subject entry field of a cataloging interface. this eliminates the need to switch screens, cut and paste, and make control character changes that may differ between the authority search interface and the cataloging interface. as a web service, assignfast can be added to existing cataloging interfaces. in this paper, the actual operation of assignfast is described , followed by how the assignfast web service is connected to an interface, and finally by a description of the web service construction. assignfast operation an authority record contains the established heading, see headings, and control numbers that may be used for linking or other future reference. the relevant fields of the fast record for motion pictures are shown here: control number fst01027285 established heading motion pictures see cinema see feature films -history and criticism see films see movies see moving-pictures in fast, the facet of each heading is known. motion pictures is a topical heading. the see references are unauthorized forms of the established heading. if someone intended to enter cinema as a subject heading, they would be directed to use the established heading motion pictures. for a typical workflow, the subject cataloger would need to leave the cataloging interface, search for “cinema” in an authority file interface, find that the established heading was motion pictures, and return to the cataloging interface to enter the established heading. the figure below shows the same process when assignfast is integrated into the cataloging interface. without leaving the cataloging interface, typing only “cine” shows both the see term that was initially intended and the established heading in a selection list. assignfast: an autosuggest-based tool |bennett, o’neill, and kammerer 36 figure 1. assignfast typical selection choices. selecting “cinema use motion pictures” enters the established term, and the entry process is complete for that subject. figure 2. assignfast selection result. the text above the entry box provides the fast id number and facet type. information technology and libraries | march 2014 37 as a web service, assignfast headings can be manipulated by the cataloging interface software after selection and before they are entered into the box. for example, one option available in the assignfast demo is marcbreaker format.13 marcbreaker combines marc field tagging and allows diacritics to be entered using only ascii characters. using marcbreaker output, assignfast returns the following for “ ”: =651 7$abrazil$zs{tilde}ao paulo$0(ocolc)fst01205761$2fast in this case, the output includes marc tagging of 651 (geographic), as well as subfie ld coding ($z) that identifies the city within brazil, that it’s a fast heading, and the fast control number. the information is available in the assignfast result to fill one or multiple input boxes and to reformat as needed for the particular cataloging interface. addition to web browser interfaces as a web service, assignfast could be added to any web-connected interface. a simple example is given here to add assignfast functionality to a web browser interface using javascript and jquery (http://jquery.com). these technologies are commonly used, and other implementation technologies would be similar. example files for this demo can be found on the oclc developers network under assignfast.14 the example uses the jquery.autocomplete function.15 first, the script packages jquery.js, jqueryui.js, and the style sheet jquery-ui.css are required. version 1.5.2 of jquery and version 1.8.7 for jquery-ui was used for this example, but other compatible versions should be fine. these are added to the html in the script and link tags. <script src="http://code.jquery.com/jquery-1.5.2.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js" type="text/javascript"></script> <script src="http://experimental.worldcat.org/fast/assignfast/js/assignfastcompl ete.js" type="text/javascript"></script> <script src=" http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery -ui.min.js" type="text/javascript" ></script> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/themes/base/jquery -ui.css " rel="stylesheet" type="text/css"> the second modification to the cataloging interface is to surround the existing subject search input box with a set of div tags. <span id="extrainformation "></span> <div class="ui-widget "> <input id="existingbox " type="text " size="60 "></input> </div> the final modification is to add javascript to connect the assignfast web service to the search input box. this function should be called from <body onload= ..> assignfast: an autosuggest-based tool |bennett, o’neill, and kammerer 38 function setuppage() { // connect the autosubject to the input areas jquery('#existingbox').autoc omplete( { source: autosubjectexample, minlength: 1, select: function(event, ui) { jquery('#extrainformation').html("fast id <b>" + ui.item.idroot + "</b> facet <b>"+ gettypefromtag(ui.item.tag)+ "</b>"); } //end select } ).data( "autocomplete" )._renderitem = function( ul, item ) { formatsuggest(ul, item);}; } //end setuppage() the source: autosubjectexample tells the autocomplete function to get the data from the autosubjectexample function, which in turns calls the assignfast web service. this is in the assignfastcomplete.js file. in select: function, the extrainformation text is rewritten with additional information returned with the selected heading. in this case, the fast number and facet are displayed. the generic _renderitem of the jquery.autocomplete function is overwritten by the formatsuggest function (found in assignfastcomplete.js) to create a display that differentiates the see from the authorized headings that are returned in the search. the version used for this example shows: see heading use authorized heading when a see heading is returned, or simply the authorized heading otherwise. web service construction the autosuggest service for a fast heading was constructed a little differently than the typical autosuggest. for a typical autosuggest for the term motion picture from the example given above, you would index just that term. as the term was typed, motion picture and other terms starting with the text entered so far would be shown until you resolved the desired heading. for example, typing in “m t” might give motion pictures motion picture music employee motivation information technology and libraries | march 2014 39 diesel motor mothers and daughters for the typical autosuggest, the term indexed is the term displayed and is the term returned when selected. for assignfast, both the established and see references are indexed. however, when typing resolves a see heading, both the see heading and its established heading are displayed. only the established heading is selected, even if you are typing the see heading. for assignfast, the “m t” result now becomes features (motion pictures) use feature films motion pictures motorcars (automobiles) use automobiles motion picture music background music for motion pictures use motion picture music motion pictures for the hearing impaired use films for the hearing impaired documentaries, motion picture use documentary films mother of god use mary, blessed virgin, saint the headings in assignfast are ranked by how often they are used in worldcat, so headings that are more common appear at the top. to place the established heading above the see heading when they are similar, the established heading is also ranked higher than the see for the same usage. assignfast can also be searched by facet, so if only topical or geographic headings are desired, only headings from these facets will be displayed. the web service uses a solr16 search engine running under tomcat.17 this provides full text search and many options for cleaning and manipulating the terms within the index. the particular option used for assignfast is the edgengramfilter.18 this option is used for autosuggest and has each word indexed one letter at a time, building to its entire length. the ndex f “c nem ” w then c nt n “c,” “c ,” “c n,” “c ne,” “c nem,” nd “c nem .” solr handles utf-8 encoded unicode for both input and output. the assignfast indexes and queries are normalized using fast normalization19 to remove punctuation, diacritics, and capitalization. fast normalization is very similar to naco normalization, although in fast nor malization the subfield indicator is replaced by a space and no commas retained. assignfast is accessed using a rest request.20 rest requests consist of urls that can be invoked via either http post or get methods, either programmatically or via a web browser.

important to many organizations, including libraries. yet a review of employment statistics and a citation analysis show that men make up the majority of the it workforce, in libraries and in the broader workforce. research from sociology, psychology, and women’s studies highlights the organizational and social issues that inhibit women. understanding why women are less evident in library it positions will help inform measures to remedy the gender disparity. t echnology not only produces goods and services, it also influences society and culture and affects our ability to work and communicate. as the computer encroaches more deeply into both workplaces and homes, encouraging participation in the development and use of technology by all segments of society is important. libraries, in particular, need to provide services and products that both appeal to and are accessible by a broad range of clientele. for libraries, information technology (it) has become vitally important to the operation of the organization. yet fewer women are active in it than men. a complex series of social and cultural biases inhibits women from participating in technology both in the library and in the larger workforce. the inclusion of more women in technology would alter the development and design of products and services as well as change the dynamic of the workplace. understanding why women reject it as it is currently practiced is necessary to understanding how to make technology more inviting for women. n occupational data studies and statistics from the broader it fields highlight discrepancies between the compensation, managerial level, and occupational roles of men and women.1 among the numbers are those showing that computer and information science fields include only 519,700 females and slightly more than 1,360,000 males in 2003.2 in the same occupational fields, men earned a median of $74,000 while women earn $63,000.3 similarly, the association of research libraries (arl) statistics from 2004 to 2008 show that men were more often employed as the heads of computer systems departments within libraries. computer systems department heads also earned higher salaries than the heads of other library departments. with the exception of 2004–5, female computer department heads were paid less than their male counterparts, despite the fact that they had more years of experience. in the 2007–8 report, men and women had the same number of years of experience, though women’s salaries lagged slightly behind those of the men, as shown in table 1.4 the availability of statistics for the heads of library technology departments belies the difficulty in counting the number of technology positions in libraries, or the broader workplace, and compiling statistics by gender. in a recent study of the job satisfaction of academic library it workers, lim comments on the complexities in identifying survey participants, “as a directory of library it workers does not exist.”5 thus, to augment the statistical data for department heads, a citation analysis was used to identify those persons involved enough in library technology to write about it. presumably, authors of articles appearing in technology-oriented journals would have interests and expertise in technology regardless of their position titles or locations within the organization. technology-related articles can and do appear in a wide variety of library journals. journals with a focus on technology were selected to avoid the dilemma of subjectively categorizing individual articles as technical or nontechnical. the journals selected provide a cross-section of association, commercial, electronic, and print publications. information technology and libraries is the journal of the library information technology association division of the american library association (ala). the journal of information science and technology (jasis&t) is an official publication of the american society for information science and technology. the not-for-profit corporation for national research initiatives publishes d-lib magazine, an table 1. library computer systems

libraries | september 2009 electronic publication on digital library research and development. all three are peer-reviewed. computers in libraries, published by information today, includes case studies and how-we-did-it articles and is not peer-reviewed. emerald publishes the peer-reviewed journal library hi tech. the author assembled statistics for the years 2006 and 2007. for the survey, regular columns, editors’ sections, reviews, short notices, and association communications were not counted. each authored article was counted. no attempt was made to include or discount an article based upon the topic. the gender of the authors was determined by notes within the journal, authors’ websites, other internet sites, or by communication with the authors. as the statistics in table 2 demonstrate, men publish in these journals at a far higher rate than women, with the exception of computers in libraries. women make up 35 percent of the authors while men make up 65 percent. jasis&t, arguably the most technical and theoretical journal in the analysis, and the journal with the most academic authorship, illustrates the highest disparity. alternatively, the publication computers in libraries contains more articles authored by women. this publication solicits articles on the application of technology—practical and less formal articles to share successes and ideas. it may be argued that female librarians simply publish less than male librarians. two additional publications, the journal of academic librarianship, published by elsevier, and college and research libraries (c&rl), published by the association of college and research libraries, were analyzed for comparison. table 3 illustrates the data for the comparison journals alone, with women making up 62 percent of the authors. female authors outnumbered male authors in the comparison journals, but women account for approximately 80 percent of u.s. librarians and are therefore publishing at a lower rate than men.6 in the interest of comparison, the author also analyzed the journal children and libraries, the journal of the association for library service to children, a division of ala. in 2006 and 2007, only four male authors were represented in children and libraries. they appeared as authors a total of eleven times. all of the remaining fifty authors are female. women made up 82 percent of the total authors while men made up 18 percent. these statistics are similar to a study conducted by hakanson and published in 2005. she analyzed articles in selected journals from the years 1980 to 2000 and found that male authors slightly outnumbered female authors, and further that articles authored by men were more likely to be referenced than those by women.7 the data gathered here are similar: 41 percent of the total authors in both technology and comparison journals are women, and 59 percent are men. male authors also are more likely to be the lead author on articles with multiple authors. again jasis&t shows the greatest disparity. computers in libraries includes more female lead authors, as shown in table 4. in the comparison journals, women are more often the lead author, as shown in table 5. both hakanson’s data and the small statistical sample reported here demonstrate that although women hold most library positions, they do not publish a comparable amount. technology journals show the most disparity between the numbers of male and female authors. together, the citation and occupational statistics illustrate the higher visibility men have in it. fewer women are evident in it as department heads, employees, academics, or authors. table 2. gender of authors in technology journals, 2006–7 publication articles female authors male authors # % # % computers in libraries 57

women in it is not just a matter of equal opportunity. according to rasmussen and hapnes, women will bring different concerns and outlooks to it. further, the products and services produced by a diverse and integrated workforce will appeal to a broader market. including more women in the it workplace will also alter the organizational environment. their ideas and interests will bring new perspectives to development discussions and likely lead to new or different systems.8 understanding why relatively few women enter it fields will help inform measures to alter the current, male-dominated dynamic. by reviewing the research in sociology, psychology, and women’s studies, the factors inhibiting women from participation in it can start to be understood. the dissuasive factors are a complex and intertwined combination of organizational culture, occupational segregation, and subtle discrimination. abilities and perceptions technology is pervasive throughout the library, and nearly all librarians develop basic technical skills as a condition of employment. librarians may develop more advanced computing skills to address a lack of technical support, to develop new services, or for professional or personal interest. correspondingly, technologists have absorbed library concepts such as description and classification. yet knowledge and ability are valued and evaluated within the social context of the organization, according to scott-dixon. the location of an occupation within the organization will influence the perception of the ability and skill required to succeed in that position.9 although the work of librarians and technologists may be similar or interdependent, the occupations are valued differently. scott-dixon’s research addresses the problem of “designating which work is technical enough to merit consideration as it work.”10 technologically proficient librarians or staff working outside of the it department will not be considered part of the library’s it staff, yet they may be performing at a technological level equal to that of the regular it staff. scott-dixon states, “assumptions about it work incorporate assumptions about who performs this work, and that work performed in traditionally nonwhite, non-male jobs is often viewed as less technical, regardless of the technological objects that are employed in the process.”11 the number of women participating in it may be higher than the statistics represent; nevertheless, women are still less directly employed in it. any contributions they make to it will be devalued as a consequence of their positions within the library organization. position and department titles also influence the perceived value of the work. to make traditional library tasks appear modern and relevant, long-established library functions have been renamed. cataloging has become metadata, catalog control has become system administration, and librarianship has become information science. the old chestnut that information science is library science for boys has an element of truth. in 2006, the average annual starting salary for librarians who categorize their positions as information science was $48,413; the average for those who categorized their positions as library science was $39,580. women who categorized their positions as information science earned an average starting salary of $46,118; men averaged $55,423.12 salary statistics substantiate the research showing that information technology positions are more highly valued and therefore more highly compensated in the library organization. likewise, men are more highly compensated than women. one of the causes of income inequality is occupational table 4. gender of lead authors in technology journals, 2006–7

totals 100 65 35 140 information technology and libraries | september 2009 segregation.13 occupational segregation occurs when positions with similar educational requirements, but different titles or locations within the organization, are valued differently.14 the difference in the salaries of traditional library department heads and the heads of technology departments is one example of income inequality within the library. according to the arl annual salary survey 2007–08, heads of computer systems departments earn more than $87,100 while heads of rare books and manuscripts departments, who have the second highest salaries, earn $80,628. the rare books and manuscripts department heads are nearly evenly divided by gender; the majority of computer systems department heads are men.15 in libraries, occupational segregation divides traditional library departments and functions from it departments and technology applications. librarians are predominately female and, as the occupational statistics show, it workers are predominately male. the result for libraries has been a gendered segregation of the library workforce.16 the results of occupational segregation are intensified by the tendency for women to avoid defining themselves as technology workers. the research by adam et al. confirms the results of several earlier studies. when asked to define their roles in the organization, men more often associate their positions with it; women tend to identify with a larger or more encompassing group within the organization, not specifically it.17 though these studies did not include librarians, it could be assumed that female librarians would respond much like their counterparts in other industries. in fact, few occupational studies conducted outside the library profession include librarians. thus it appears that women choose to be excluded from an occupational group that is well compensated, integral to the organization, and considered highly skilled. not only do women define their positions as non– it, but women also underestimate their technical skills. hargittai and shafer reviewed a number of studies investigating the self-assessment of computer skills. in those studies, women test at the same skill level as men but consistently underrate their technical ability. hargittai and shafer conducted a study of internet skills that draws the same conclusion.18 organizational culture women may underestimate their abilities and disassociate with it in part because of the perception of it organizational culture.19 technical positions are associated with long and irregular hours, leading to the assumption that family and home responsibilities will cause women to be less able to contribute. as ramsey and mccorduck note, those assumptions are not associated with men’s work.20 they emphasize that while women “often shoulder more family responsibilities than men . . . the presumption more than the reality tends to limit women’s advancement.”21 the perception of a high commitment level is fostered by the computing industries. the stereotype of the solitary computer geek, typing away in physical, though not virtual, isolation with a social life revolving around the technology is not entirely accurate. yet guzman, stam, and stanton have studied it as an occupational subculture. they call the perceived demands of the subculture “extreme and unusual,” with long hours and constant need for self reeducation.22 the appearance of high cost in time and capital is one way that the already-initiated keep outsiders out. the use of specialized language and jargon, stories of long hours spent, and complaints about end users are all means of solidifying organizational boundaries. the ramsey and mccorduck report points to a perception by some women that the long hours are often “a status symbol, a sign of machismo.”23 all occupational groups participate in us-versus-them behavior however; since it is gendered, the subculture effectively excludes women and exacerbates the segregation. according to guzman, stam, and stanton’s research, one of the hallmarks of the it subculture is the sense of control over other groups within the organization. yet the subculture also shares a sense of fulfillment in assisting others with technology.24 the esoteric knowledge held by it workers is essential to the operation of most organizations, in particular libraries. this gives the subculture an inordinate sense of power.25 the computing professions appear to be linked with masculinity and power, at least in western cultures. melanie wilson writes, “the qualities required for entry to the professions and success in them are seen as masculine.”26 masculine occupations tend to be associated with skill, learning, and hard work. construction, business, and now it have a preponderance of male professionals. masculine occupations are more prestigious and better compensated. wacjman writes, “to be in command of the very latest technology signifies being involved in directing the future, so it is a highly valued and mythologized activity.”27 the idea that women’s skills are more instinctive makes them less valued, and feminized occupations tend to be associated with the innate behaviors.28 wilson points to research indicating that “women’s work tends to be regarded as semi-skilled merely because it is women’s work.”29 women are a higher percentage of elementary school teachers, nurses, and care givers, and those positions receive modest compensation compared to occupations typically held by men. specific to libraries, technology subfields may be seen as acceptable positions for men in an occupation traditionally dominated by women. as the research suggests, an increase in the number of women involved in technology would devalue those fields. roos and reskin explored the effect of an increase gender, technology, and libraries | lamont 141 in the numbers of women on occupational status. in a 1990 paper they wrote, traditionally, “women’s” jobs have been both lowerpaying and less valued than “men’s.” occupational incumbents have thus been chagrined to learn that their occupation is feminizing, fearful of a drop in wages and prestige. this fear has a valid empirical basis: the percentage female in an occupation is negatively correlated with occupational earnings.30 an influx of women into library it would likely devalue the subfield and depress wages; as such, occupational segregation is one means of protecting wages and influence. women are often deterred from entering or excelling in an occupation through subtle discrimination. because the sexist actions or words are not always recognized as discriminatory, subtle sexism is difficult to define. the repetition of the behaviors and language over time creates a sense that those patterns are acceptable, and they become more difficult to change.31 examples of subtle sexism include the expectation that the women will be more responsible for social occasions involving food or more responsible for the staff lounge or lunch room. often the informal exchange of information and skills, so-called boy’s-room knowledge, eludes women because they are excluded from masculine socializing. in addition, men may be assigned different, usually less clerical tasks, and women are often associated with the softer tasks of user support, help desks and interfaces.32 although subtle discrimination occurs in all work places, not just libraries, the effects in a gender-segregated workplace are compounded. confronted with a complex series of social, cultural, and organizational cues, women are made to feel less competent and less comfortable with technology. the association of women’s positions with lower wages and prestige serves to sustain the occupational segregation and justify the subtle discrimination that hinders women. sometimes perception creates reality. it would be a mistake to group all women as a whole, expecting that the experiences of all are exactly alike, just as not all men are technologically adept. socioeconomic factors, as well as ethnic and geographic differences, influence the abilities and desires of women and men to succeed in technology professions. yet the smaller number of women in technology subfields of librarianship implies an almost “symbolic image of the discipline as masculine, which in turn reinforces the minority position of women.”33 likewise, the far greater number of women writing in children’s librarianship simply reinforces this subfield as feminine. according to alksnis, “on the demand side, jobs are often seen as requiring the characteristics of the group that already dominates it.”34 the lack of women in the it field continues to reinforce the stereotype and perpetuate the imbalance. n conclusion to remedy the underrepresentation of women in it, it would be simple to call for greater educational opportunities for girls, mentoring programs for young professional women, and economic incentives to retain mid-career women. the situation, however, is not simple. a series of organizational, societal, and cultural perceptions inhibit women from associating or identifying with it. rasmussen and hapnes refer to a combination of organizational culture and gender politics that discourage women.35 instead of a focus on the numbers of women in it, librarians should work to transform the organizational culture. as technology progresses, the definition of technology work must be reevaluated and the entries into the technology fields must be redefined. in short, what constitutes it must be rethought, recast, and revalued as technology develops. in the library specifically, it and librarianship have much in common. at present, the library has a dichotomized workforce of female librarians and male it workers. over time, the skills of librarians and technologists will blend. if managed properly, the best of classic library theory and practice will combine with it into a dynamic and diverse workforce as well as a thriving and innovative organization. references and notes

loading marc metadata crosswalked to dspace dublin core (dc) in a poster session.2 mishra and others developed a perl script to create the dspace archive directory for batch import of electronic theses and dissertations (etds) extracted with a java program from an in-house bibliographic database.3 mundle used perl scripts to batch process etds for import into dspace with marc catalog records or excel spreadsheets as the source metadata.4 brownlee used python scripts to batch process comma-separated values (csv) files exported from filemaker database software for ingest via the dspace item importer.5 more in-depth descriptions of batch loading are provided by thomas; kim, dong, and durden; proudfoot et al.; witt and newton; drysdale; ribaric; floyd; and averkamp and lee. however, irrespective of repository software, each describes a process to populate their repositories dissimilar to the workflows developed for the knowledge bank in approach or source data. thomas describes the perl scripts used to convert marc catalog records into dc and to create the archive directory for dspace batch import.6 kim, dong, and durden used perl scripts to semiautomate the preparation of files for batch loading a university of texas harry ransom humanities research center (hrc) collection into dspace. the xml source metadata they used was generated by the national library of new zealand metadata extraction tool.7 two subsequent projects for the hrc revisited the workflow described by kim, dong, and durden.8 proudfoot and her colleagues discuss importing metadata-only records from departmental refbase, thomson reuters endnote, and microsoft access databases into eprints. they also describe an experimental perl script written to scrape lists of publications from personal websites to populate eprints.9 two additional workflow examples used citation databases as the data source for batch loading into repositories. witt and newton provide a tutorial on transforming endnote metadata for digital commons with xslt (extensible stylesheet language transformations).10 drysdale describes the perl scripts used to convert thomson reuters reference manager files into xml for the batch loading of metadata-only records into the university of glascow’s eprints repository.11 the glascow eprints batch workflow is additionally described by robertson and nixon and greig.12 several workflows were designed for batch loading etds into repositories. ribaric describes the automatic this paper describes batch loading workflows developed for the knowledge bank, the ohio state university’s institutional repository. in the five years since the inception of the repository approximately 80 percent of the items added to the knowledge bank, a dspace repository, have been batch loaded. most of the batch loads utilized perl scripts to automate the process of importing metadata and content files. custom perl scripts were used to migrate data from spreadsheets or comma-separated values files into the dspace archive directory format, to build collections and tables of contents, and to provide data quality control. two projects are described to illustrate the process and workflows. t he mission of the knowledge bank, the ohio state university’s (osu) institutional repository, is to collect, preserve, and distribute the digital intellectual output of osu’s faculty, staff, and students.1 the staff working with the knowledge bank have sought from its inception to be as efficient as possible in adding content to dspace. using batch loading workflows to populate the repository has been integral to that efficiency. the first batch load into the knowledge bank was august 29, 2005. over the next four years, 698 collections containing 32,188 items were batch loaded, representing 79 percent of the items and 58 percent of the collections in the knowledge bank. these batch loaded collections vary from journal issues to photo albums. the items include articles, images, abstracts, and transcripts. the majority of the batch loads, including the first, used custom perl scripts to migrate data from microsoft excel spreadsheets into the dspace batch import format for descriptive metadata and content files. perl scripts have been used for data cleanup and quality control as part of the batch load process. perl scripts, in combination with shell scripts, have also been used to build collections and tables of contents in the knowledge bank. the workflows using perl scripts to automate batch import into dspace have evolved through an iterative process of continual refinement and improvement. two knowledge bank projects are presented as case studies to illustrate a successful approach that may be applicable to other institutional repositories. ■■ literature review batch ingesting is acknowledged in the literature as a means of populating institutional repositories. there are examples of specific batch loading processes minimally discussed in the literature. branschofsky and her maureen p. walsh (walsh.260@osu.edu) is metadata librarian/ assistant professor, the ohio state university libraries, columbus, ohio. 118 information technology and libraries | september 2010 relational database postgresql 8.1.11 on the red hat enterprise linux 5 operating system. the structure of the knowledge bank follows the hierarchical arrangement of dspace. communities are at the highest level and can be divided into subcommunities. each community or subcommunity contains one or more collections. all items—the basic archival elements in dspace—are contained within collections. items consist of metadata and bundles of bitstreams (files). dspace supports two user interfaces: the original interface based on javaserver pages (jspui) and the newer manakin (xmlui) interface based on the apache cocoon framework. at this writing, the knowledge bank continues to use the jspui interface. the default metadata used by dspace is a qualified dc schema derived from the dc library application profile.18 the knowledge bank uses a locally defined extended version of the default dspace qualified dc schema, which includes several additional element qualifiers. the metadata management for the knowledge bank is guided by a knowledge bank application profile and a core element set for each collection within the repository derived from the application profile.19 the metadata librarians at osul create the collection core element sets in consultation with the community representatives. the core element sets serve as metadata guidelines for submitting items to the knowledge bank regardless of the method of ingest. the primary means of adding items to collections in dspace, and the two ways used for knowledge bank ingest, are (1) direct (or intermediated) author entry via the dspace web item submission user interface and (2) in batch via the dspace item importer. recent enhancements to dspace, not yet fully explored for use with the knowledge bank, include new ingest options using simple web-service offering repository deposit (sword), open archives initiative object reuse and exchange (oai-ore), and dspace package importers such as the metadata encoding and transmission standard submission information package (mets sip) preparation of etds from the internet archive (http:// www.archive.org/) for ingest into dspace using php utilities.13 floyd describes the processor developed to automate the ingest of proquest etds via the dspace item importer.14 also using proquest etds as the source data, averkamp and lee described using xslt to transform the proquest data to bepress’ (the berkeley electronic press) schema for batch loading into a digital commons repository.15 the knowledge bank workflows described in this paper use perl scripts to generate dc xml and create the archive directory for batch loading metadata records and content files into dspace using excel spreadsheets or csv files as the source metadata. ■■ background the knowledge bank, a joint initiative of the osu libraries (osul) and the osu office of the chief information officer, was first registered in the registry of open access repositories (roar) on september 28, 2004.16 as of december 2009 the repository held 40,686 items in 1,192 collections. the knowledge bank uses dspace, the open-source java-based repository software jointly developed by the massachusetts institute of technology libraries and hewlett-packard.17 as a dspace repository, the knowledge bank is organized by communities. the fifty-two communities currently in the knowledge bank include administrative units, colleges, departments, journals, library special collections, research centers, symposiums, and undergraduate honors theses. the commonality of the varied knowledge bank communities is their affiliation with osu and their production of knowledge in a digital format that they wish to store, preserve, and distribute. the staff working with the knowledge bank includes a team of people from three osul areas—technical services, information technology, and preservation—and the contracted hours of one systems developer from the osu office of information technology (oit). the osul team members are not individually assigned full-time to the repository. the current osul team includes a librarian repository manager, two metadata librarians, one systems librarian, one systems developer, two technical services staff members, one preservation staff member, and one graduate assistant. the knowledge bank is currently running dspace 1.5.2 and the figure 1. dspace simple archive format archive_directory/ item_000/ dublin_core.xml--qualified dublin core metadata contents --text file

studies the issues of the ohio journal of science ojs was jointly published by osu and the ohio academy of science (oas) until 1974, when oas took over sole control of the journal. the issues of ojs are archived in the knowledge bank with a two year rolling wall embargo. the issues for 1900 through 2003, a total of 639 issues containing 6,429 articles, were batch loaded into the knowledge bank. due to rights issues, the retrospective batch loading project had two phases. the project to digitize ojs began with the 1900–1972 issues that osu had the rights to digitize and make publicly available. osu later acquired the rights for 1973–present, and (accounting for the embargo period) 1973–2003 became phase 2 of the project. the two phases of batch loads were the most complicated automated batch loading processes developed to date for the knowledge bank. to batch load phase 1 in 2005 and phase 2 in 2006, the systems developers working with the knowledge bank wrote scripts to build collections, generate dc xml from the source metadata, create the archive directory, load the metadata and content files, create tables of contents, and load the tables of contents into dspace. the ojs community in the knowledge bank is organized by collections representing each issue of the journal. the systems developers used scripts to automate the building of the collections in dspace because of the number needed as part of the retrospective project. the individual articles within the issues are items within the collections. there is a table of contents for the articles in each issue as part of the collection homepages.21 again, due to the number required for the retrospective project, the systems developers used scripts to automate the creation and loading of the tables of contents. the tables of contents are contained in the html introductory text section of the collection pages. the tables of contents list title, authors, and pages. they also include a link to the item record and a direct link to the article pdf that includes the file size. for each phase of the ojs project, a vendor contracted by osul supplied the article pdfs and an excel spreadsheet with the article-level metadata. the metadata format. this paper describes ingest via the dspace batch item importer. the dspace item importer is a command-line tool for batch ingesting items. the importer uses a simple archive format diagramed in figure 1. the archive is a directory of items that contain a subdirectory of item metadata, item files, and a contents file listing the bitstream file names. each item’s descriptive metadata is contained in a dc xml file. the format used by dspace for the dc xml files is illustrated in figure 2. automating the process of creating the unix archive directory has been the main function of the perl scripts written for the knowledge bank batch loading workflows. a systems developer uses the test mode of the dspace item importer tool to validate the item directories before doing a batch load. any significant errors are corrected and the process is repeated. after a successful test, the batch is loaded into the staging instance of the knowledge bank and quality checked by a metadata librarian to identify any unexpected results and script or data problems that need to be corrected. after a successful load into the staging instance the batch is loaded into the production instance of the knowledge bank. most of the knowledge bank batch loading workflows use excel spreadsheets or csv files as the source for the descriptive item metadata. the creation of the metadata contained in the spreadsheets or files has varied by project. in some cases the metadata is created by osul staff. in other cases the metadata is supplied by knowledge bank communities in consultation with a metadata librarian or by a vendor contracted by osul. whether the source metadata is created in-house or externally supplied, osul staff are involved in the quality control of the metadata. several of the first communities to join the knowledge bank had very large retrospective collection sets to archive. the collection sets of two of those early adopters, the journal issues of the ohio journal of science (ojs) and the abstracts of the osu international symposium on molecular spectroscopy currently account for 59 percent of the items in the knowledge bank.20 the successful batch loading workflows developed for these two communities—which continue to be active content suppliers to the repository—are presented as case studies. figure 2. dspace

table 1. the systems developers used the mapping as a guide to write perl scripts to transform the vendor metadata into the dspace schema of dc. the workflow for the two phases was nearly identical, except each phase had its own batch loading scripts. due to a staff change between the two phases of the project, a former osul systems developer was responsible for batch loading phase 1 and the oit systems developer was responsible for phase 2. the phase 1 scripts were all written in perl. the four scripts written for phase 1 created the archive directory, performed database operations to build the collections, generated the html introduction table of contents for each collection, and loaded the tables of contents into dspace via the database. for phase 2, the oit systems developer modified and added to the phase 1 batch processing scripts. this case study focuses on phase 2 of the project. batch processing for phase 2 of ojs the annotated scripts the oit systems developer used for phase 2 of the ojs project are included in appendix a, available on the italica weblog (http://ital-ica .blogspot.com/). a shell script (mkcol.sh) added collections based on a listing of the journal issues. the script performed a login as a selected user id to the dspace web interface using the web access tool curl. a subsequent simple looping perl script (mkallcol.pl) used the stored credentials to submit data via this channel to build the collections in the knowledge bank. the metadata.pl script created the archive directory for each collection. the oit systems developer added the pdf file for each item to unix. the vendor-supplied metadata was saved as unicode text format and transferred to unix for further processing. the developer used vi commands to manually modify metadata for characters illegal in xml (e.g., “<” and “&”). (although manual steps were used for this project, the oit systems developer improved the perl scripts for subsequent projects by adding code for automated transformation of the input data to help ensure xml validity.) the metadata.pl script then processed each line of the metadata along with the corresponding data file. for each item, the script created the dc xml file and the contents file and moved them and the pdf file to the proper directory. load sets for each collection (issue) were placed in their own subdirectory, and a load was done for each subdirectory. the items for each collection were loaded by a small perl script (loaditems. pl) that used the list of issues and their collection ids and called a shell script (import.sh) for the actual load. the tables of contents for the issues were added to the knowledge bank after the items were loaded. a perl script (intro.pl) created the tables of contents using the metadata and the dspace map file, a stored mapping of item received from the vendor had not been customized for the knowledge bank. the ojs issues were sent to a vendor for digitization and metadata creation before the knowledge bank was chosen as the hosting site of the digitized journal. the osu digital initiatives steering committee 2002 proposal for the ojs digitization project had predated the knowledge bank dspace instance. osul staff performed quality-control checks of the vendor-supplied metadata and standardized the author names. the vendor supplied the author names as they appeared in the articles—in direct order, comma separated, and including any “and” that appeared. in addition to other quality checks performed, osul staff edited the author names in the spreadsheet to conform to dspace author-entry convention (surname first). semicolons were added to separate author names, and the extraneous ands were removed. a former metadata librarian mapped the vendor-supplied table 1. mapping of vendor metadata to

to what was used to create the collections. installintro.sh used curl to simulate a user adding the data to dspace by performing a login as a selected user id to the dspace web interface. a simple looping perl script (ldallintro.pl) called installintro.sh and used the stored credentials to submit the data for the tables of contents. the abstracts of the osu international symposium on molecular spectroscopy the knowledge bank contains the abstracts of the papers presented at the osu international symposium on molecular spectroscopy (mss), which has met annually since 1946. beginning with the 2005 symposium, the complete presentations from authors who have authorized their inclusion are archived along with the abstracts. the mss community in the knowledge bank currently contains 17,714 items grouped by decade into six collections. the six collections were created “manually” via the dspace web interface prior to the batch loading of the items. the retrospective years of the symposium (1946–2004) were batch loaded in three phases in 2006. each symposium year following the retrospective loads was batch loaded individually. retrospective mss batch loads the majority of the abstracts for the retrospective loads were digitized by osul. a vendor was contracted by osul to digitize the remainder and to supply the metadata for the retrospective batch loads. the files digitized by osul were sent to the vendor for metadata capture. osul provided the vendor a metadata template derived from the mss core element set. the metadata taken from the abstracts comprised author, affiliation, title, year, session number, sponsorship (if applicable), and a full transcription of the abstract. to facilitate searching, the formulas and special characters appearing in the titles and abstracts were encoded using latex, a document preparation system used for scientific data. the vendor delivered the metadata in excel spreadsheets as per the spreadsheet template provided by osul. quality-checking the metadata was an essential step in the workflow for osul. the metadata received for the project required revisions and data cleanup. the vendor originally supplied incomplete files and spreadsheets that contained data errors, including incorrect numbering, data in the wrong fields, and inconsistency with the latex encoding. the three knowledge bank batch load phases for the retrospective mss project corresponded to the staged receipt of metadata and digitized files from the vendor. the annotated scripts used for phase 2 of the project, which included twenty years of the osu international symposium between 1951 and 1999, are included in appendix b, available on the italica weblog. the oit systems developer saved the metadata as a tab-separated file and added it to unix along with the abstract files. a perl script (mkxml2.pl) transformed the metadata into dc xml and created the archive directories for loading the metadata and abstract files into the knowledge bank. the script divided the directories into separate load sets for each of the six collections and accounted for the inconsistent naming of the abstract files. the script added the constant data for type and language that was not included in the vendor-supplied metadata. unlike the ojs project, where multiple authors were on the same line of the metadata file, the mss phase 2 script had to code for authors and their affiliations on separate lines. once the load sets were made, the oit systems developer ran a shell script to load them. the script (import_ collections.sh) was used to run the load for each set so that the dspace item import command did not need to be constructed each time. annual mss batch loads a new workflow was developed for batch loading the annual mss collection additions. the metadata and item files for the annual collection additions are supplied by the mss community. the community provides the symposium metadata in a csv file and the item files in a tar archive file. the symposium uses a web form for latex–formatted abstract submissions. the community processes the electronic symposium submissions with a perl script to create the csv file. the metadata delivered in the csv file is based on the template created by the author, which details the metadata requirements for the project. the oit systems developer borrowed from and modified earlier perl scripts to create a new script for batch processing the metadata and files for the annual symposium collection additions. to assist with the development of the new script, i provided the developer a mapping of the community csv headings to the knowledge bank dc fields. i also provided a sample dc xml file to illustrate the desired result of the perl transformation of the community metadata into dc xml. for each new year of the symposium, i create a sample dc xml result for an item to check the accuracy of the script. a dc xml example from a 2009 mss item is included in appendix c, available on the italica weblog. unlike the previous retrospective mss loads in which the script processed multiple years of the symposium, the new script processes one year at a time. the annual symposiums are batch loaded individually into one existing mss decade collection. the new script for the annual loads was tested and refined by loading the 2005 symposium into the staging instance of the 122 information technology and libraries | september 2010 ■■ summary and conclusion each of the batch loads that used perl scripts had its own unique features. the format of content and associated metadata varied considerably, and custom scripts to convert the content and metadata into the dspace import format were created on a case-by-case basis. the differences between batch loads included the delivery format of the metadata, the fields of metadata supplied, how metadata values were delimited, the character set used for the metadata, the data used to uniquely identify the files to be loaded, and how repeating metadata fields were identified. because of the differences in supplied metadata, a separate perl script for generating the dc xml and archive directory for batch loading was written for each project. each new perl script borrowed from and modified earlier scripts. many of the early batch loads were firsts for the knowledge bank and the staff working with the repository, both in terms of content and in terms of metadata. dealing with communityand vendor-supplied metadata and various encodings (including latex), each of the early loads encountered different data obstacles, and in each case solutions were written in perl. the batch loading code has matured over time, and the progression of improvements is evident in the example scripts included in the appendixes. batch loading can greatly reduce the time it takes to add content and metadata to a repository, but successful knowledge bank. problems encountered with character encoding and file types were resolved by modifying the script. the metadata and files for the symposium years 2005, 2006, and 2007 were made available to osul in 2007, and each year was individually loaded into the existing knowledge bank collection for that decade. these first three years of community-supplied csv files contained author metadata inconsistent with knowledge bank author entries. the names were in direct order, uppercase, split by either a semicolon or “and,” and included extraneous data, such as an address. the oit systems developer wrote a perl script to correct the author metadata as part of the batch loading workflow. an annotated section of that script illustrating the author modifications is included in appendix d, available on the italica weblog. the mss community revised the perl script they used to generate the csv files by including an edited version of this author entry correction script and were able to provide the expected author data for 2008 and 2009. the author entries received for these years were in inverted order (surname first) and mixed case, were semicolon separated, and included no extraneous data. the receipt of consistent data from the community for the last two years has facilitated the standardized workflow for the annual mss loads. the scripts used to batch load the 2009 symposium year are included in appendix e, which appears at the end of this text. the oit systems developer unpacked the tar file of abstracts and presentations into a directory named for the year of the symposium on unix. the perl script written for the annual mss loads (mkxml<year>. pl) was saved on unix and renamed mkxml2009.pl. the script was edited for 2009 (including the name of the csv file and the location of the directories for the unpacked files and generated xml). the csv headings used by the community in the new file were checked and verified against the extract list in the script. once the perl script was up-to-date and the base directory was created, the oit systems developer ran the perl script to generate the archive directory set for import. the import.sh script was then edited for 2009 and run to import the new symposium year into the staging instance of the knowledge bank as a quality check prior to loading into the live repository. the brief item view of an example mss 2009 item archived in the knowledge bank is shown in figure

loaded. along with testing scripts and checking imported metadata by first batch loading to a development or staging environment, quality control of the supplied metadata is an integral step. the flexibility of perl allowed testing and revising to accommodate problems encountered with how the metadata was supplied for the heterogeneous collections batch loaded into the knowledge bank. however, toward the goal of standardizing batch loading workflows, the staff working with the knowledge bank iteratively refined not only the scripts but also the metadata requirements for each project and how those were communicated to the data suppliers with mappings, explicit metadata examples, and sample desired results. the efficiency of batch loading workflows is greatly enhanced by consistent data and basic standards for how metadata is supplied. batch loading is not only an extremely efficient means of populating an institutional repository, it is also a valueadded service that can increase buy-in from the wider campus community. it is hoped that by openly sharing examples of our batch loading scripts we are contributing to the development of an open library of code that can be borrowed and adapted by the library community toward future institutional repository success stories. ■■ acknowledgments i would like to thank conrad gratz, of osu oit, and andrew wang, formerly of osul. gratz wrote the shell scripts and the majority of the perl scripts used for automating the knowledge bank item import process and ran the corresponding batch loads. the early perl scripts used for batch loading into the knowledge bank, including the first phase of ojs and mss, were written by wang. parts of those early perl scripts written by wang were borrowed for subsequent scripts written by gratz. gratz provided the annotated scripts appearing in the appendixes and consulted with the author regarding the description of the scripts. i would also like to thank amanda j. wilson, a former metadata librarian for osul, who was instrumental to the success of many of the batch loading workflows created for the knowledge bank. references and notes 1. the ohio state university knowledge

lib-mocs-kmc364-20131012113604 233 lit a a ward, 1980: maurice j. freedman s. michael malinconico this is the third presentation of the lit a award for outstanding achievement. the first two honored individuals whose achievements can be said to have created the discipline we know as library automation. the first award went to fred kilgour whose vision, daring, and entrepreneurial and managerial skills changed the way libraries operate almost overnight, and may in the increasingly stringent economic times ahead have helped ensure the economic viability of libraries. the second award went to henriette avram, whose untiring efforts on behalf of the marc formats and their promulgation is only just short of legendary. this year's winner distinguished himself in a somewhat different manner. his contributions did not lead to the development of new automated systems or services. rather, his outstanding achievement lies in the creative and pioneering use he made of technology in support of a clear vision of effective library service. his contribution comes from the depth of sensitivity and understanding he brought to the application of technology to library service. much to our go<;>d fortune, he has chosen to share with us through his many writings the insights he has found in his study of the fit between technology and the delivery of effective library service. this year's winner shares the distinction, with the two previous winners, of being a former president of the division. in fact, he presided over the change from the venerable acronym isad to the new name of the division: library and information technology association (lita). it gives me particular pleasure to present this year's award, as it goes not simply to an esteemed colleague but to a valued friend. i first met maurice (mitch) freedman at the first ala conference i attended-the midwinter meeting of 1972. the first session i attended at that conference was a meeting of the committee on library automation (cola). i had gone to that meeting to report on nypl's automated cataloging system, which had that month become fully operational with the publication of the book catalogs of the research libraries and of the mid-manhattan library. following the cola program, mitch approached me, introduced himself, and inquired about the possibility of using the nypl system to produce hennepin county's catalog. the consequences of that afternoon were most salutary both for the hennepin county library (hcl) and for me personally. hcl acquired at no cost an automated bibliographic control system, and i gained a friendship that has endured for nearly a decade. thus, rather than dwelling on mitch's professional accomplishments-which are already well known to you-1 would prefer to say a few words about the man himself. perhaps the best way to characterize him is to describe to you his office at 234 journal of library automation vol. 14/3 september 1981 maurice freedman (left) receiving 1980 lita award presented by s. michael malinconico (right). columbia university. prominently displayed on the walls are two enormous posters, one of bertrand russell and another of lenny bruce. a perhaps odd pair until one realizes that these men had one important attribute in common: neither of them accepted, without incontrovertible proof, truths supported by conventional wisdom alone. mitch, like the philosopher and satirist whose images grace the walls of his office, is an iconoclast who insists on more than the endorsement of reigning authority before he will embrace an idea; and he will work tirelessly to change the prevailing wisdom if he finds that it serves to frustrate rather than aid the delivery of the kind and quality of library service to which he feels the patrons of libraries are entitled. likewise, though he was among the pioneers who helped introduce sophisticated technologies such as automation and micrographics into the operation of libraries, he has always maintained a healthy skepticism, which has prevented him from being seduced by the dry voices of the hollow men who proclaim marvels that are in reality only gilded figures of straw. just as lenny bruce refused to accept contemporary conventions regarding language and behavior, mitch freeman has refused to accept the sanctity of lc subject terminology. he, sanford berman, and joan marshall have served for more than a decade as lc's conscience, prodding our phlegmatic, de facto national library to action. just as bertrand russell returned to the axioms of giuseppe peano in an attempt to secure the foundation of mathematics in formal logic and to lita award 235 free that discipline of fuzzy thinking, mitch has returned to the principles articulated by antonio panizzi and seymour lubetzky, as the tests by which to judge the claims of the self-assured mountebanks who regale us with newly coined bibliographic wisdom. in this regard i anxiously await the completion of his doctoral dissertation, in which he explores the philosophical underpinnings of theories of bibliographic control (a work that would have proved most useful during the protracted emotional debate that surrounded aacr2). i expect that it must be particularly gratifying for mitch to accept his award in this particular city. although his physical roots are in the northeast, i rather think his intellectual and spiritual roots are here, or more precisely, in the city across the bay-berkeley. it was just about twenty years ago that mitch, after graduating from rutgers university, newark, enrolled as a graduate student in philosophy at the university of california, berkeley. while at berkeley, his sense of social justice and utter disdain for unsupported dogma-could one expect less of a student of philosophy?led him to become active in the free speech movement. thus, we find very early in his career a concern for social issues, a concern that reemerged in his active involvement with the social responsibilities round table shortly after joining the library profession. before leaving berkeley, mitch earned his degree in library science. thus, he earned his degree from one of the most prestigious library schools on the west coast, and now plies his trade as associate professor at one of the most prestigious library schools on the east coast, the columbia university school of library service. if he is only moderately successful in conveying to his students his dedication to the delivery of quality library service, his steadfast conviction that technical services is in reality the first step in the provision of effective public service, and a respect for the supremacy of principle over expedience, his graduating classes will constitute a more lasting and meaningful award than this simple gesture conferred upon him by his professional colleagues. enhancing opac records for discover | griffis and ford 191 patrick griffis and cyrus ford enhancing opac records for discovery this article proposes adding keywords and descriptors to the catalog records of electronic databases and media items to enhance their discovery. the authors contend that subject liaisons can add value to opac records and enhance discovery of electronic databases and media items by providing searchable keywords and resource descriptions. the authors provide an examination of opac records at their own library, which illustrates the disparity of useful keywords and descriptions within the notes field for media item records versus electronic database records. the authors outline methods for identifying useful keywords for indexing opac records of electronic databases. also included is an analysis of the advantages of using encore’s community tag and community review features to allow subject liaisons to work directly in the catalog instead of collaborating with cataloging staff. a t the university of nevada las vegas (unlv) libraries’ discovery mini-conference, there was a wide range of initiatives and ideas presented. some were large-scale initiatives that focused on designing search platforms and systems as well as information architecture schemas that would enhance library resource discovery. but there was not much focus on enhancing the representation of library resources within the construct of bibliographic records in the opac. since searching platforms can only be as useful as the information available for searching, and since opac records are the method for representing the majority of library resources, we thought it important that the prominence of opac records and how they represent library resources be considered in the mini-conference. to that end, our presentation focused on enhancing the opac records for nonbook items to support their discoverability as opposed to focusing on search systems and information architecture schemas. our proposition was that subject liaisons’ expertise could be used to enhance opac records by including their own keyword search terms and descriptive summaries in opac records for electronic databases as well as records of media items. this proposition acts as a moderate approach to initiatives that call for opac records to be opened for usergenerated content in that this approach provides subject liaison mediation and expertise to modify records. as such, this approach may serve as an effective stopgap in cases where there is resistance toward permitting social tagging and user descriptions within opac records. such an initiative also is scalable, allowing liaisons to provide as few or as many terms as they want. such an initiative would require collaboration between cataloging staff and subject liaisons. n disparity between media and database records at unlv libraries, terms included in the notes fields of bibliographic records are indexed for keyword searching. in the case of media items, there is extensive use of notes to include descriptive terms that enhance discoverability for users. for example, notes for films indicate any awards the film has won as well as festivals in which it has been featured (see figure 1). as a result, users can discover films through keyword searches of film awards or film festivals. a film student who is searching “cannes film festival” via a keyword search will generate results that include films owned by unlv libraries that have been featured at that festival. these keyword-searchable notes add value and discoverability for this type of material, and subject liaisons can be a source for such information. while it appears that notes in media records are heavily populated with a variety of user-centric information, there is relatively little use of descriptive notes for figure 1. the notes field in an opac record of a film item patrick griffis (patrick.griffis@unlv.edu) is business librarian and cyrus ford (cyrus.ford@unlv.edu) is special formats catalog librarian, university of nevada las vegas libraries. 192 information technology and libraries | december 2009 electronic databases (see figure 2). for databases, notes traditionally include information about access restrictions and mode of access while overlooking information representing the content of the resource. these fields could be utilized for specific terms relating to database content not adequately covered by the library of congress subject headings (lcsh). subject liaisons have specialized knowledge of which databases work best for unique content areas, class assignments, and information needs. this user-centric knowledge can be used to enhance database discovery if liaisons were to provide catalogers with information and descriptors to add to the record. as an example, at unlv libraries there is one particular database that provides a strengths, weaknesses, opportunities, and threats (swot) analysis for companies, but that natural language term isn’t found anywhere in the general database summary listing or subject headings. if it were added to a note field as part of a description or as a labeled descriptor, then students could easily find this database to complete their assignments. this proposal is scalable, allowing liaisons to provide as few or as many key terms as they want, depending on their preference or on the vagaries of a particular database. subject liaisons could opt to add a few major terms from their own knowledge and expertise that they feel will add value for patrons searching the opac. subject liaisons also could mine the index and thesaurus terms of individual databases to identify prominent content areas for individual databases to find useful keywords. n mining electronic database index descriptors electronic databases typically have subject matter taxonomies developed by experts who assign descriptors to journal articles. subject liaisons could mine these taxonomies to identify predominant descriptors for individual databases to add to the database catalog records. predominance of a subject descriptor could be determined by examining the relative number of articles that are assigned to that descriptor. such a strategy of indexing key predominant subject descriptors identified from database subject matter taxonomies could serve to uncover unique content areas not served with lcsh. a different application of this strategy could be employed for identifying predominant and emerging research areas for particular groups. subject liaisons could conduct a citation analysis of articles authored by members of a particular research group to record and codify the subject descriptors of each article. once codified, an analysis could determine the most predominant subject descriptors for articles authored by that particular group. this could serve as a baseline for identifying emerging research areas and their terms. both types of analysis have potential to provide useful keyword terms for database records. n using encore’s community features in 2008, unlv libraries purchased and implemented the innovative interfaces’ encore discovery platform, which provides a google-like interface for searching the public catalog and the ability to narrow results using facets such as location, year, language, and format. encore also includes many display features that showcase the information provided in the bibliographic records. two of encore’s web 2.0 features provide users with the ability to contribute data to records via community tags and community reviews. unlv requires users to enter a valid library barcode number and pin. subject liaisons could use the community reviews feature to add descriptive summaries of items to encore records independently, without the need for cataloging staff to edit a marc record. however, the content of community reviews are not indexed for searching and thus only add value at the point when a user is determining whether the resources they have retrieved are valuable for them. on the other hand, if a community tag is added to an item, that tag is included in the community tags section figure 2. the notes field in an opac record of an electronic database enhancing opac records for discover | griffis and ford 193 of the encore result display and becomes an indexed keyword for searches in encore (see figure 3). if that tag term is searched in encore’s keyword search, the bibliographic record attached to that tag term will be included in the results list under the community tags facet. since these community tags are searchable, subject liaisons can add keywords to encore records without collaboration with cataloging staff. however, this provides limited success because the keyword is included and indexed only in encore records—not in the opac records. also, the community tags facet must be selected from the results display for the encore record tags to be searchable. n the case for collaboration as described above, keywords and descriptions added by subject liaisons into encore records have inherent discovery limitations when compared to a cataloger adding the same information directly to the marc bibliographic record. the advantages of collaboration between subject liaisons and catalogers is clear, and subject librarians at unlv libraries have experienced similar collaboration in efforts in the past. in 2006, subject librarians at unlv libraries were offered the opportunity to create their own descriptions of electronic resources through an initiative to update the summary descriptions for the electronic databases portion of the libraries’ website. at that time, all existing electronic database summaries were those used by the database publishers. the project provided subject liaisons the option to create custom summary descriptions to represent electronic databases in their own terms. each subject liaison had a document file for their descriptions, and the website editors used them to update the electronic databases list on the libraries’ website. this particular initiative serves as one example of the willingness of subject liaisons to share their subject expertise to enhance the representation of library resources through collaboration with technical services staff. as such, collaboration between subject liaisons and catalogers to allow liaisons to add terms to opac records of electronic databases and media items could prove to be both effective and feasible as an initiative toward enhancing the discovery of library resources. figure 3. encore community tag lita cover 2, cover 3, cover 4 index to advertisers editorial the authors of “the state of rfid applications in libraries,” that appeared in the march 2006 issue, inadvertently included two sentences that are near quotations from a commentary by peter warfield and lee tien in the april 8, 2005 issue of the berkeley daily planet. on page 30 immediately following footnote 24, the authors wrote: “the eugene public library reported ‘collision’ problems on very thin materials and on videos as well as false readings from the rfid security gates. collision problems mean that two or more tags are close enough to cancel the signals, making them undetectable by the rfid checkout and security systems.” warfield and lien wrote: “the eugene (ore.) public library reported ‘collision’ problems on very thin materials and on videos as well as ‘false

nancy eaton, dean of university libraries and scholarly communication, penn state university (and former chair of the oclc board); and carol mandel, dean of libraries, new york university. from oclc the members are elisabeth niggeman, director, deutschesbibliothek; jane ryland, senior scientist, internet 2; and betsy wilson, dean of university libraries, university of washington.” and from james michalko, currently president and ceo of rlg, and by the time you read this, vice president, rlg-programs development, oclc: “we are combining the practices of rlg and oclc in a very powerful way— by putting together the traditions of rlg and oclc we are creating a robust new venue for research institutions and new capacity that will provide unique and beneficial outcomes to the whole community.” by now, all lita members and ital readers know that in 1967, fred kilgour founded oclc; and was the founding editor of the journal of library automation (jola—vol. 1, no. 1 was published in march, 1968), which, with but a mild outcry from serials librarians, changed its title to information technology and libraries in 1982. this afternoon (6/15/06), i called fred. he and his wife eleanor reminisced about the earliest days, and then i asked him for his comments on the oclc-rlg merger. because he had had the first words about both oclc and jola, as it were, i told him that i would like for him to have the last. and this is what he said, “at long last!” fred kilgour died on july 31, 2006, aged 92. a tribute posted by alane wilson of oclc may be read at http:// scanblog.blogspot.com/2006/07/frederick-g-kilgour -1914-2006.html editorial: a confession, a speculation, and a farewell john webb john webb (jwebb@wsu.edu) is a librarian emeritus, washington state university and editor of information technology and libraries. editorial | webb 115 from our readers | eden 93 bradford lee edenfrom our readers the new user environment: the end of technical services? editor’s note: “from our readers” is an occasional feature highlighting ital readers’ letters and commentaries on timely issues. technical services: an obsolete term used to describe the largest component of most library staffs in the twentieth century. that component of the staff was entirely devoted to arcane and mysterious processes involved in selecting, acquiring, cataloging, processing, and otherwise making available to library users physical material containing information content pieces (incops). the processes were complicated, expensive, and time-consuming, and generally served to severely limit direct service to users both by producing records that were difficult to understand and interpret, even by other library staff, and by consuming from 75–80 percent of the library’s financial and personnel resources. in the twenty-first century, the advent of new forms of publication and new techniques for providing universal records and universal access to information content made the organizational structure obsolete. that change in organizational structure, more than any other single factor, is generally credited as being responsible for the dramatic improvement in the quality of library service that has occurred in the first decade of the twenty-first century. t here are many who would say that i was the one who wrote this quotation. i didn’t, and it is, in fact, more than twenty-five years old!1 while i was beginning to research and prepare for this article, i began as most users today start their search for information: i started with google. granted, i rarely go beyond the first page of results (as most user surveys indicate), but the paucity of links made me click to the next screen. there, at number 16, was a scanned article. jackpot! i thought as i started perusing the contents of this resource online, thinking to myself how the future had changed so dramatically since 1984, with the emergence of the internet and the laptop, all of the new information formats, and the digitization of information. ahh, the power of full text! after reading through the table of contents, introduction, and the first chapter, i noticed that some of the pages were missing. mmmm, obviously some very shoddy scanning on the part of google. but no, i finally realized that only part of this special issue was available on google. obviously, i missed the statement at the bottom of the front scan of the book: “this is a preview. the total pages displayed will be limited. learn more.” and thus the issues regarding copyright reared their ugly head. when discussing the new user environment, there are many demands facing libraries today. in a report by martha bates, citing the principle of least effort first attributed to philologist george zipf and quoted in the calhoun report to the library of congress, she states: people do not just use information that is easy to find; they even use information that they know to be of poor quality and less reliable—so long as it requires little effort to find—rather than using information they know to be of high quality and reliable, though harder to find . . . despite heroic efforts on the part of librarians, students seldom have sufficiently sustained exposure to and practice with library skills to reach the point where they feel real ease with and mastery of library information systems.2 according to the final report of bibliographic services task force of the university of california libraries, users expect the following: ■■ one system or search to cover a wide information universe (e.g., google or amazon) ■■ enriched metadata (e.g., onix, tables of contents, and cover art) ■■ full-text availability ■■ to move easily and seamlessly from a citation about an item to the item itself—discovery alone is not enough ■■ systems to provide a lot of intelligent assistance ■❏ correction of obvious spelling errors ■❏ results sorting in order of relevance to their queries ■❏ help in navigating large retrievals through logical subsetting or topical maps or hierarchies ■❏ help in selecting the best source through relevance ranking or added commentary from peers and experts or “others who used this also used that” tools ■❏ customization and personalization services ■■ authenticated single sign-on ■■ security and privacy ■■ communication and collaboration ■■ multiple formats available: e-books, mpeg, jpeg, rss and other push technologies, along with traditional, tangible formats ■■ direct links to e-mail, instant messaging, and sharing ■■ access to online virtual communities ■■ access to what the library has to offer without actually having to visit the library3 bradford lee eden (eden@library.ucsb.edu) is associate university librarian for technical services & scholarly communication, university of california, santa barbara. 94 information technology and libraries | june 2010 what is there in this new user environment for those who work in technical services? as indicated in the opening quote, would a dramatic improvement in library services occur if technical services were removed from the organizational structure? even in 1983, the huge financial investment that libraries made in the organization and description of information, inventory, workflows, and personnel was recognized; today, that investment comes under intense scrutiny as libraries realize that we no longer have a monopoly on information access, and to survive we need to move forward more aggressively into the digital environment than ever before. as marcum stated in her now-famous article, ■■ if the commonly available books and journals are accessible online, should we consider the search engines the primary means of access to them? ■■ massive digitization radically changes the nature of local libraries. does it make sense to devote local efforts to the cataloging of unique materials only rather than the regular books and journals? ■■ we have introduced our cataloging rules and the marc format to libraries all over the world. how do we make massive changes without creating chaos? ■■ and finally, a more specific question: should we proceed with aacr3 in light of a much-changed environment?4 there are larger internal issues to consider here as well. the budget situation in libraries requires the application of business models to workflows that have normally not been questioned nor challenged. karen calhoun discusses this topic in a number of her contributions to the literature: when catalog librarians identify what they contribute to their communities with their methods (the cataloging rules, etc.) and with the product they provide (the catalog), they face the danger of “marketing myopia.” marketing myopia is a term used in the business literature to describe a nearsighted view that focuses on the products and services that a firm provides, rather than the needs those products and services are intended to address.5 for understanding the implementation issues associated with the leadership strategy, it is important to be clear about what is meant by the “excess capacity” of catalogs. most catalogers would deny there is excess capacity in today’s cataloging departments, and they are correct. library materials continue to flood into acquisitions and cataloging departments and staff can barely keep up. yet the key problem of today’s online catalog is the effect of declining demand. in healthy businesses, the demand for a product and the capacity to produce it are in balance. research libraries invest huge sums in the infrastructure that produces their local catalogs, but search engines are students and scholars’ favorite place to begin a search. more users bypass catalogs for search engines, but research libraries’ investment in catalogs—and in the collections they describe—does not reflect the shift in user demand.6 i have discussed this exact problem in recent articles and technical reports as well.7 there have to be better, more efficient ways for libraries to organize and describe information not based on the status quo of redundant “localizing” of bibliographic records. a good analogy would be the current price of gas and the looming transportation crisis. for many years, americans have had the luxury of being able to purchase just about any type of car, truck, suv, hummer, etc., that they wanted on the basis of their own preferences, personalities, and incomes, not on the size of the gas tank or on the mileage per gallon. why not buy a mercedes over a kia? but with gas prices now well above the average person’s ability to consistently fill their gas tank without mortgaging their future, the market demands that people find alternative solutions in order to survive. this has meant moving away from the status quo of personal choice and selection toward a more economic and sustainable model of informed fuel-efficiency transportation, so much so that public transportation is now inundated with more users than it can handle, and consumers have all but abandoned the truck and suv markets. libraries have long worked in the mercedes arena, providing features such as authority control, subject classification, and redundant localizing of bibliographic records that were essential when libraries held the monopoly on information access but are no longer cost-efficient—nor even sane—strategies in the current information marketplace. users are not accessing the opac anymore; well-known studies indicate that more than 80 percent of information seekers begin their search on a web search engine. libraries are investing huge resources in staffing and priorities fiddling with marc bibliographic records in a time when they are struggling to survive and adapt from a monopoly environment to being just one of many players in the new information marketplace. budgets are stagnant, staffing is at an all-time low, new information formats continue to appear and require attention, and users are no longer patient nor comfortable working with our clunky opacs.8 why do libraries continue to support an infrastructure of buying and offering the same books, cds, dvds, journals, etc., at every library, when the new information environment offers libraries the opportunity to showcase and present their unique information resources and one-of-a-kind collections to the world? special collections materials held by every major research and public library in the world can now be digitized, and from our readers | eden 95 sparse library resources need to be adjusted to compete and offer these unique collections and their services to our users and the world. the october 2007 issue of computers in libraries is devoted solely to articles related to the enhancement, usability, appropriateness, and demise of the library opac. interesting articles include “fac-back-opac: an open source solution interface to your library system,” “dreaming of a better ils,” “plug your users into library resources with opensearch plug-ins,” delivering what people need, when and where they need it,” “the birth of a new generation of library interfaces,” and “will the ils soon be as obsolete as the card catalog?” an especially interesting quote is given by cervone, then assistant university librarian for information technology at northwestern university: what i’d like to see is for the catalog to go away. to a great degree, it is an anachronism. what we need from the ils is a solid, business-process back end that would facilitate the functions of the library that are truly unique such as circulation, acquiring materials, and “cataloging” at the item level for what amounts to inventory-control purposes. most of the other traditional ils functions could be rolled over into a centralized system, like oclc, that would be cooperatively shared. the catalog itself should be treated as just another database in the world of resources we have access to. a single interface to those resources that would combine our local print holdings, electronic text (both journal and ebook), as well as multimedia material is what we should be demanding from our vendors.9 one book that needs to be required reading for all librarians, especially catalogers, is weinberger ’s everything is miscellaneous.10 he describes the three orders of order (self organization, metadata, and digital); provides an extensive history of how western civilization has ordered information, specifically the links to nineteenth-century victorianism; and the concepts of lumping and splitting. in the end, weinberger argues that the digital environment allows users to manipulate information into their own organization system, disregarding all previous organizational attempts by supposed experts using outdated and outmoded systems. in the digital disorder of information, an object (leaf) can now be placed on many shelves (branches), figuratively speaking, and this new shape of knowledge brings out four strategic principles: 1. filter on the way out, not on the way in. 2. put each leaf on as many branches as possible. 3. everything is metadata and everything can be a label. 4. give up control. it is this last principle that libraries have challenges with. whether we agree with this principle or not, it has already happened. arguing about it, ignoring it, or just continuing to do business as usual isn’t going to change the fact that information is user-controled and user initiated in the digital environment. so, where do we go from here? the future of technical services (and its staff) far be it from me to try to predict the future of libraries as viable, and more importantly marketable, information organizations in this new environment. one has only to examine the quotations from the first issues of technical services quarterly to see what happens to predictions and opinions. titles of some of the contributions (from 1983, mind you) are worthy of mention: “library automation in the year 2000,” “musings on the future of the catalog,” and “libraries on the line.” there are developments, however, that require reexamination and strategic brainstorming regarding the future of library bibliographic organization and description. the appearance of worldcat local will have a tremendous impact on the disappearance of proprietary vendor opacs. there will no longer be a need for an integrated library system (ils); with worldcat local, the majority of the world’s marc bibliographic records are available in a library 2.0 format. the only things missing are some type of inventory and acquisitions module that can be formatted locally and a circulation module. if oclc could focus their programming efforts on these two services and integrate them into worldcat local, library administrators and systems staff would no longer have to deal with proprietary and clunky opacs (and their huge budgetary lines), but could use the power of web 2.0 (and hopefully 3.0) tools and services to better position themselves in the new information marketplace. another major development is the google digitization project (and other associated ventures). while there are some concerns about quality and copyright,11 as well as issues related to the disappearance of print and the time involved to digitize all print,12 no one can deny the gradual and inevitable effect that mass digitization of print resources will have in the new information marketplace. just the fact that my research explorations for this article brought up digitized portions of the 1983 technical services quarterly articles is an example. more and more, published print information will be available in full-text online. what effect will this have on the physical collection that all libraries maintain, not only in terms of circulation, but also in terms of use of space, preservation, and collection development? no one knows for sure, but if the search strategies and information discovery patterns of our users are any 96 information technology and libraries | june 2010 indication, then we need to be strategically preparing and developing directions and options. automatic metadata generation has been a topic of discussion for a number of years, and jane greenberg’s work at the university of north carolina–chapel hill is one of the leading examples of research in this area.13 while there are still viable concerns about metadata generation without any type of human intervention, semiautomatic and even nonlibrary-facilitated metadata generation has been successful in a number of venues. as libraries grapple with decreased budgets, multiplying formats, fewer staff to do the work, and more retraining and reprofessional development of existing staff, library administrators have to examine all options to maximize personnel as well as budgetary resources. incorporating new technologies and tools for generating metadata without human intervention into library workflows should be viewed as a viable option. user tagging would be included in this area. even intner, a long-time proponent of traditional technical services, has written that generating cataloging data automatically would be of great benefit to the profession, and that more tools and more programming ought to be focused toward this goal.14 so, with print workflows being replaced by digital and electronic workflows, how can administrators assist their technical services staff to remain viable in this new information environment? how can technical services staff not only help themselves but their supervisors and administrators to incorporate their unique talents, expertise, education, and experience toward the type of future scenarios indicated above? competencies and challenges for technical services staff there are some good opinions available for assisting technical services staff with moving into the new environment. names have power, whether we like to admit it or not, and changing the name from “technical services” to something more understandable to our users, let alone our colleagues within the library, is one way to start. names such as “collections and data management services” or “reference data services” have been mentioned.15 an interesting quote sums up the dilemma: it’s pretty clear that technical services departments have long been the ugly ducklings in the library pond, trumped by a quintet of swans: reference departments (the ones with answers for a grateful public); it departments (the magicians who keep the computers humming); children’s and youth departments (the warm and fuzzy nurturers); other specialty departments (the experts in good reads, music, art, law, business, medicine, government documents, av, rare books and manuscripts, you-name-it); and administrative groups (the big bosses). part of the trouble is that the rest of our colleagues don’t really know what technical services librarians do. they only know that we do it behind closed doors and talk about it in language no one else understands. if it can’t be seen, can’t be understood, and can’t be discussed, maybe it’s all smoke and mirrors, lacking real substance. it’s easy to ignore.16 ruschoff mentions competencies for technical services librarians in the new information environment: comfortable working in both print and digital worlds, specialized skills such as foreign languages and subject area expertise, comfortable working in both digital and web-based technologies (suggesting more computing and technology skills), expertise in digital asset management, and problem-solving analytical skills.17 in a recent blog posting summarizing a presentation at the 2008 ala annual conference on this topic, comparisons between catalogers going extinct or retooling are provided. the following is a summary of that post: converging trends ■■ more catalogers work at the support-staff level than as professional librarians. ■■ more cataloging records are selected by machines. ■■ more catalog records are being captured from publisher data or other sources. ■■ more updating of catalog records is done via batch processes. ■■ libraries continue to deemphasize processing of secondary research products in favor of unique primary materials. what are our choices? ■■ behind door number one—the extinction model. ■■ behind door number two—the retooling model. how it’s done ■■ extinction ■❏ keep cranking about how nobody appreciates us. ■❏ assert over and over that we’re already doing everything right—why should we change? ■❏ adopt a “chicken little” approach to envisioning the future. ■■ retooling ■❏ considers what catalogers already do. ■❏ look for support. ■❏ find a new job. what catalogers do ■■ operate within the boundaries of detailed standards. ■■ describe items one-at-a-time. ■■ treat items as if they are intended to fit carefully from our readers | eden 97 within a specific application—the catalog. ■■ ignore the rest of the world of information. what metadata librarians do ■■ think about descriptive data without preconceptions around descriptive level, granularity, or descriptive vocabularies. ■■ consider the entirety of the discovery and access issues around a set or collection of materials. ■■ consider users and uses beyond an individual service when making design decisions—not necessarily predetermined. ■■ leap tall buildings in a single bound. what new metadata librarians do ■■ be aware of changing user needs. ■■ understand the evolving information environment. ■■ work collaboratively with technical staff. ■■ be familiar with all metadata formats and encoding metadata. ■■ seek out tall buildings—otherwise jumping skills will atrophy. the cataloger skill set ■■ aacr2, lc, etc. the metadata librarian skill set ■■ views data as collections, sets, streams. ■■ approaches the task as designing data to “play well with others.” characteristics of our new world ■■ no more ils ■■ bibliographic utilities are unlikely to be the central node for all data. ■■ creation of metadata will become more decentralized. ■■ nobody knows how this will all shake out, but metadata librarians will be critical in forging solutions.18 while the above summary focuses on catalogers and their future, many of the directions also apply to any librarian or support staff member currently working in technical services. in a recent educause review article, brantley lists a number of mantras that all libraries need to repeat and keep in mind in this new information environment: ■■ libraries must be available everywhere. ■■ libraries must be designed to get better through use. ■■ libraries must be portable. ■■ libraries must know where they are. ■■ libraries must tell stories. ■■ libraries must help people learn. ■■ libraries must be tools of change. ■■ libraries must offer paths for exploration. ■■ libraries must help forge memory. ■■ libraries must speak for people. ■■ libraries must study the art of war.19 you will have to read the article to find out about that last point. the above mantras illustrate that each of these issues must also be aligned with the work done by technical services departments in support of the rest of the library’s services. and there definitely isn’t one right way to move forward; each library with its unique blend of services and staff has to define, initiate, and engender dialogue on change and strategic direction, and then actively make decisions with integrity and vigor toward both its users and its staff. as calhoun indicates, there are a number of challenges to feasibility for next steps in this area, some technically oriented but many based on our own organizational structures and strictures: ■■ difficulty achieving consensus on standardized, simplified, more automated workflows. ■■ unwillingness or inability to dispense with highly customized acquisitions and cataloging operations. ■■ overcoming the “not invented here” mindset preventing ready acceptance of cataloging copy from other libraries or external sources. ■■ resistance to simplifying cataloging. ■■ inability to find and successfully collaborate with necessary partners (e.g., ils vendors). ■■ difficulty achieving basic levels of system interoperability. ■■ slow development and implementation of necessary standards. ■■ library-centric decision making; inability to base priorities on how users behave and what they want ■■ limited availability of data to support management decisions. ■■ inadequate skill set among library staff; unwillingness or inability to retrain. ■■ resistance to change from faculty members, deans, or administrators.20 moving forward in the new information world in a recent discussion on the autocat electronic discussion list regarding the client-business paradigm now being impressed on library staff, an especially interesting quote puts the entire debate into perspective: the irony of this discussion is that our patrons/users/ clients [et al.] expect to be treated as well as business customers. they pay tuition or taxes to most of our institutions and expect to have a return in value. and a very large percentage of them care about the differences between the government services vs. business 98 information technology and libraries | june 2010 arguments we present. what they know is that when they want something, they want it. more library powers-that-be now come from the world of business rather than libraries because of the pressure on the bottom line. business administrators are viewed, even by those in public administration, as being more fiscally able than librarians. i would recommend that we fuss less about titles and semantics and develop ways to show the value of libraries to the public.21 wheeler, in a recent educause review article, documents a number of “eras” that colleges and universities have gone through in recent history.22 first is the “era of publishing,” followed by the “era of participation” with the appearance of the internet and its social networking tools. the next era, the “era of certitude,” is one in which users will want quick, timely answers to questions, along with some thought about the need and context of the question. wheeler espouses five dimensions that tools of certitude must have: reach, response, results, resources, and rights. he explains these dimensions in regards to various tools and services that libraries can provide through human–human, human–machine, and machine–machine interaction.23 wheeler sees extensive rethinking and reengineering by libraries, campuses, and information technology to assist users to meet their information needs. are there ways that technical services staff can assist in these efforts? although somewhat dated, calhoun’s extensive article on what is needed from catalogers and librarians in the twenty-first century expounds a number of salient points.24 in table 1, she illustrates some of the many challenges facing traditional library cataloging, providing her opinion on what the challenges are, why they exist, and some solutions for survivability and adaptability in the new marketplace.25 one quote in particular deserves attention: at the very least, adapting successfully to current demands will require new competencies for librarians, and i have made the case elsewhere that librarians must move beyond basic computer literacy to “it fluency”—that is, an understanding of the concepts of information technology, especially applying problem solving and critical thinking skills to using information technology. raising the bar of it fluency will be even more critical for metadata specialists, as they shift away from a focus on metadata production to approaches based on it tools and techniques on the one hand, and on consulting and teamwork on the other. as a result of the increasing need for it fluency among metadata specialists, they may become more closely allied with technical support groups in campus computing centers. the chief challenges for metadata specialists will be getting out of library back rooms, becoming familiar with the larger world of university knowledge communities, and developing primary contacts with the appropriate domain experts and it specialists.26 getting out of the back room and interacting with users seems to be one of the dominant themes of evolving technical services positions to fit the new information marketplace. putting web 2.0 tools and services into the library opac has also gained some momentum since the launch of the endeca-based opac at north carolina state university. as some people have stated, however, putting “lipstick on a pig” doesn’t change the fundamental problems and poor usability of something that never worked well in the first place.27 in their recent article, jia mi and cathy weng tried to answer the following questions: why is the current opac ineffective? what can libraries and librarians do to deliver an opac that is as good as search engines to better serve our users?28 of course, the authors are biased toward the opac and wish to make it better, given that the last sentence in their abstract is, “revitalizing the opac is one of the pressing issues that has to be accomplished.” users’ search patterns have already moved away from the opac as a discovery tool; why should personnel and resource investment continue to be allocated toward something that users have turned away from? in their recommendations, mi and weng indicate that system limitations, not fully exploiting the functionality already made available by ilss, and the unsuitability of marc standards to online bibliographic display are the primary factors to the ineffectiveness of library opacs. exactly. debate and discussion on autocat after the publication of their article again shows the line drawn between conservative opinions (added value, noncommercialization, and overall ideals of the library profession and professional cataloging workflows) and the newer push for open-source models, junking the opac, and learning and working with non-marc metadata standards and tools. conclusion from an administrative point of view, there are a number of viable options for making technical services as efficient as possible, in its current emanation: ■■ conduct a process review of all current workflows, following each type of format from receipt at loading dock to access by user. revise and redesign workflows for efficiency. ■■ eliminate all backlogs, incorporating and standardizing various types of bibliographic organization (from brief records to full records, using established criteria of importance and access). ■■ as much as possible, contract with vendors to make from our readers | eden 99 all print materials shelf-ready, establishing and monitoring profiles for quality and accuracy. establish a rate of error that is amenable to technical services staff; once that error rate is met, review incoming print materials only once or twice a year. ■■ assure technical services staff that their skills, experience, and attention to detail are needed in the electronic environment, and provide training and professional development to assist them in scanning and digitizing unique collections, learning non-marc metadata standards, improving project management, and performing consultation training to interact with faculty and students who work with data sets, metadata, and research planning. support and actively work for revised job reclassification of library support staff positions. most libraries are forced to work with fewer staff, and it is essential that current personnel are valued for their institutional knowledge and skill sets (knowledge management philosophy). library administrations need to emphasize to their staff that the organization has a vested interest in providing them with the tools and training they need to assist the organization in the new information marketplace. the status quo of technical services operations is no longer viable or cost-effective; all of us must look at ways to regain market share and restructure our organizations to collaborate and consult with users regarding their information and research needs. no longer is it enough to just provide access to information; we must also provide tools and assistance to the user in manipulating that information. to end, i would like to quote from a few of the articles from that 1983 issue of technical services quarterly i have alluded to throughout this chapter: like all prognostications, predictions about cataloging in a fully automated library may bear little resemblance to the ultimate reality. while the future cataloging scenario discussed here may seem reasonable now, it could prove embarrassing to read 10–20 years hence. still, i would be pleasantly surprised if, by the year 2000, ts operations are not fully integrated, ts staff has not been greatly reduced, there has not been a large-scale jump in ts productivity accompanied by a dramatic decline in ts costs, and if most of us are not cooperating through a national database.29 in conclusion, i will revert to my first subject, the uncertain nature of predictions. in addition to the fearless predictions already recorded, i predict that some of these predictions will come true and perhaps even most of them. some of them will come true, but not in the time anticipated, while others never will. let us hope that the influences not guessed that will prevent the actualization of some of these predictions will be happy ones, not dire. however they turn out, i predict that in ten years no one will remember or really care what these predictions were.30 technical services as we know them now may well not exist by the end of the century. the aims of technical services will exist for as long as there are libraries. the technical services quarterly may well have changed its name and its coverage long before then, but its concerns will remain real and the work to which many of us devote our lives will remain worthwhile. there can be few things in life that are as worth doing as enabling libraries to fulfill their unique and uniquely important role in culture and civilization.31 twenty-five years have come and gone; some of the predictions in this first issue of technical services quarterly came true, many of them did not. there have been dramatic changes in those twenty-five years, most of which were unforeseen, as they always are. what is a certainty is that libraries can no longer sustain or maintain the status quo in technical services. what also is a certainty is that technical services staff, with their unique skills, talents, abilities, and knowledge in relation to the organization and description of information, are desperately needed in the new information environment. it is the responsibility of both library administrators and technical services staff to work together to evolve and redesign workflows, standards, procedures, and even themselves to survive and succeed into the future. references 1. norman d. stevens, “selections from a dictionary of libinfosci terms,” in “beyond ‘1984’: the future of technical services,” special issue, technical services quarterly 1, no. 1–2 (fall/winter 1983): 260. 2. marcia j. bates, “improving user access to library catalog and portal information: final report,” (paper presented at the library of congress bicentennial conference on bibliographic control for the new millennium, june 1, 2003): 4, http://www.loc.gov/catdir/bibcontrol/2.3batesreport6-03 .doc.pdf (accessed apr. 7, 2009). see also karen calhoun, “the changing nature of the catalog and its integration with other discovery tools,” final report to the library of congress, mar. 17, 2006, 25, http://www.loc.gov/catdir/calhoun-report-final .pdf (accessed apr. 7, 2009). 3. university of california libraries bibliographic services task force, “rethinking how we provide bibliographic services for the university of california,” final report, dec. 2005, 8, http://libraries.universityofcalifornia.edu/sopag/bstf/final. pdf (accessed apr. 7, 2009). 4. deanna b. marcum, “the future of cataloging,” library resources & technical services 50, no. 1 (jan. 2006): 9, http://www .loc.gov/library/reports/catalogingspeech.pdf (accessed apr. 100 information technology and libraries | june 2010 7, 2009). 5. karen calhoun, “being a librarian: metadata and metadata specialists in the twenty-first century,” library hi tech 25, no. 2 (2007), http://www.emeraldinsight.com/insight/view contentservlet?filename=published/emeraldfulltextarticle/ articles/2380250202.html (accessed apr. 7, 2009). 6. calhoun, “the changing nature of the catalog,” 15. 7. bradford lee eden, “ending the status quo,” american libraries 39, no. 3 (mar. 2008): 38;

public library could not have made the above decisions if it did not have a complete online file of all its holdings (including even reference materials that never circulate). but since this data did exist (after a five-year bar-coding effort) and since more than forty online terminals were already in place throughout the library system to access the online file, the decision not to include locations or holdings in the microform catalog seemed reasonable . in the longer-range future (1990?), it is very likely that the entire catalog will be available online. in the meantime, the tucson public library did not want to divide its resources maintaining two location records, but rather wanted to concentrate resources in maintaining one accurate record of locations available as widely as possible throughout the library system (by installing more online terminals for staff and public use). was this decision a sound one? we don't know. the microform catalog has not yet been introduced for public use. by the end of this year we should have some preliminary answers to this question. references 1. robin w. macdonald and j. mcree elrod, "an approach to developing computer catalogs," college & research libraries 34:202--8 (may 1973). a structure code for machine readable library catalog record formats herbert h. hoffman: santa ana college, santa ana, california. libraries house many types of publications in many media, mostly print on paper, but also pictures on paper, print and pictures on film, recorded sound on plastic discs, and others. these publications are of interest to people because they contain recorded information. more precisely said, because they contain units of intellectual, artistic, or scholarly creation that collectively can be called "works." one could say simply that library materials consist of documents that are stored and cataloged because they contain works. the structure of publications into documents (or "books") and works, the clear distinction between the concept of the information container as opposed to the contents, deserves more attention than it has received so far from bibliographers and librarians. the importance of the distinction between books and works has been hinted at by several theoreticians, notably lubetzky. however, the idea was never fully developed. the cataloging implications of the structural diversity among documents were left unexplored. as a consequence, librarians have never disentangled the two terms book and work . from the paris principles and the marc formats to the new second edition of the anglo-american cataloguing rules, the terms book and work are used loosely and interchangeably, now meaning a book, now a work proper, now part of a work , now a group of books. such ambiguity can be tolerated as long as each person involved knows at each step which definition is appropriate when the term comes up. but as libraries ease into the age of electronic utilities and computerized catalogs based on records read by machine rather than interpreted by humans, a considerably greater measure of precision will have to be introduced into library work. as one step toward that goal an examination of the structure of publications will be in order. the items that are housed in libraries, regardless of medium, are of two types. they are either single documents, or they are groups of two or more documents. items that contain two or more documents are either finite items (all published at once, or with a first and a last volume identified) or they are infinite items (periodicals, intended to be continued indefinitely at intervals). schematically, these three types of bibliographic items in libraries can be represented as shown in figure l. it should be noted that all publications, all documents, all bibliographic items in lid d ... d do __ _ fig. 1. three types of bibliographic items: top, single-document item; center, finite multiple-document item; bottom, infinite multipledocument item. braries, can be assigned to one of these three structures. there are no exceptions. all bibliographic items, furthermore, contain works. an item may contain one single work. but an item may also contain several works. schematically, the two situations can be represented as shown in figure 2. an item that is composed of several documents and contains several works may have one work in each document, or several per document. schematically, the two possibilities can be represented as shown in figure 3. it is possible, of course, for an item to fig . . 2. top, single-work document (example: a typical novel); bottom, multiple-work document (example: a collection of plays). communications 113 fig. 3. top, one work per document; bottom, several works per document . be composed of several documents but to contain only one work. figure 4 is a schematic representation of this case. mixed structures are also possible, as in the schematic shown in figure 5. ign oring the mixed structure that is only a combination of two "pure" structures, the foregoing information can be combined into a table that shows seven possible publication types that differ from each other in terms of structure (figure 6). all bibliographic items, whether composed of one document or many, are known by a title . these titles can be called item titles. in the case of a singledocument item (structures a and c), item title and document title are, of course, identical. but in the case of some multiple-document items (publications of types d, e, f, and g, for example), two possibilities exist: the documents that make up the item may or may not have their own individual document titles. for purposes of fig. 4. multivolume work (example: a very long novel in two volumes). fig. 5. finite multi-document item containing many works, mixed structure. 114 journal of library automation vol. 14/2 june 1981 one several documents document per item per item one \.jork

individual document titles can be described under one of two principles. the entire item can be treated as a unit. elsewhere i have coined a term for this treatment: the set description principle .1 but it is also possible to treat each document as a separate publication, to describe it under the book description principle . if we combine all these considerations we find that we can assign to each bibliographic item that is added to a library's collection one of the thirteen codes shown in figure 7. how can these codes be useful? taking a look into the future, let us imagine an online catalog system supported by a database that contains the records of a library's holdings . the records in such a database are entered in a definite format . in this format, whatever it will be called , there will be data fields for titles, authors, physical descriptions , subject headings, document numbers, and much else. i propose that to these fields one other be added: the structure code . the structure code would add a new dimension to the retrieval of recorded infinite infinite b d e f g formation. here are a few specific examples . consider a search for material on subject x. qualify the search argument by structure codes 1, 3, 7, and 12. result: the search will yield only major monographic works, defined as items of types a, b,f, and g. note that subject x assigned to such items is a true subject heading. the materials retrieved in this example would all be works dealing specifically with the topic x. but the same term assigned to an item coded, say, 6, would not be a true subject heading. the term here would only give a broad general summary of what the works in the item are about. the structure code adds sophistication to the retrieval process by enabling a searcher to distinguish between specific subject designators and mere summary subject headings. a search that excludes codes 2, 4, 5, and 6 limits output to materials that are not just collections of essays. the stratagem used in card catalogs to reach the same result is the qualification of a subject heading by terms denoting format, such as the subdivisions congresses or addresses, essays, lectures . this method of qualifying subject headings has never been done communications ll5 structure code publication type description principle: book (b) or set (s) schematic 1 a 2 c 3 b 4 d 5 d 6 d 7 f 8 f 9 e 10

structure code would introduce uniformity and consistency. present-day card catalogs list publica116 journal of library automation vol. 14/2 june 1981 tions only. they do not list the individual works that may be contained in publications. if an analytic catalog were to be built into a computerized system at some time in the future , the structure code would be a great help in the redesign, because it makes it easy to spot items that need analytics, namely those that contain embedded works, or codes 2, 4, 5, 6, 8, 9, 10, 11, and 13. a searcher working with such an analytic catalog could use the code to limit output to manageable stages-first all items of type c, for example; then broadening the search to include those of type d; and so forth, until enough relevant material has been found. the structure code would also be useful in the displayed output. if codes 5 or 8 appeared together with a bibliographic description on the screen, this would tell the catalog user that the item retrieved is a set of many separately titled documents. a complete list of those titles can then be displayed to help the searcher decide which of the documents are relevant for him. in the card catalog this is done by means of contents notes . not all libraries go to the trouble of making contents notes, though, and not all contents notes are complete and rtliable . the structure code would ensure consistency and completeness of contents information at all times. codes 10 and 13 in a search output, analogously, would tell the user that the item is a serial with individual issue titles. there is no mechanism in the contemporary card catalog to inform readers of those titles. codes 4 and 7 would tell that the document is part of a finite set, and so forth. it has been the general experience of database designers that a record cannot have too many searchable elements built into its format. no sooner is one approach abandoned "because nobody needs it," than someone arrives on the scene with just that requirement. it can be anticipated, then, that once the structure code is part of the standard record format, catalog users will find many other ways to work the code into search strategies. it can also be anticipated that the proposed structure code, by adding a factor of selectivity, will help catalogers because it strengthens the authority-control aspect of machine-readable catalog files. if two publications bear identical titles, for example, and one is of structure 1, the other of structure 6, then it is clear that they cannot possibly be the same items. however, if they are of structures 1 and 7, respectively, extra care must be taken in cataloging, for they could be different versions of the same work. determination of the structure of an item is a by-product of cataloging, for no librarian can catalog a book unless he understands what the structure of that book is-one or more works, one or more documents per item, open or closed set, and so forth . it would therefore be very cheap at cataloging time to document the already-performed structure analysis and express this structure in the form of a code. references l. herbert h.

imseptember_ital_ozeran_for_proofing managing metadata for philatelic materials megan ozeran information technology and libraries | september 2017 7 abstract stamp collectors frequently donate their stamps to cultural heritage institutions. as digitization becomes more prevalent for other kinds of materials, it is worth exploring how cultural heritage institutions are digitizing their philatelic materials. this paper begins with a review of the literature about the purpose of metadata, current metadata standards, and metadata that are relevant to philatelists. the paper then examines the digital philatelic collections of four large cultural heritage institutions, discussing the metadata standards and elements employed by these institutions. the paper concludes with a recommendation to create international standards that describe metadata management explicitly for philatelic materials. introduction postage stamps have existed since great britain introduced them in 1840 as a way to prepay postage. historian and professor winthrop boggs (1955) points out that postage stamps have been collected by individuals since 1841, just a few months after the first stamps were issued (5). to describe this collection and research, the term philately was coined by a french stamp collector, georges herpin, who “combined two greek words philos (friend, amateur) and atelia (free, exempt from any charge or tax, franked)” (boggs 1955, 7). thus postage stamps and related materials, such as the envelopes to which they have been affixed, are considered philatelic materials. in the united states, numerous societies have formed around philately, such as the american philatelic society, the postal history society, the precancel stamp society, and the sacramento philatelic society (in northern california). the definitive united states authority on stamps and stamp collecting for nearly 150 years has been the scott postage stamp catalogue, which was first created by john walter scott in 1867 (boggs 1955, 6). the scott catalogue “lists nearly all the postage stamps issued by every country of the world” (american philatelic society 2016). philately is a massively popular hobby, and cultural heritage institutions have amassed large collections of postage stamps through collectors’ donations. in this paper, i will examine how cultural heritage institutions apply metadata to postage stamps in their digital collections. libraries, archives, and museums have obtained specialized collections of stamps over the decades, and they have used various ways to describe these collections, such as through creating finding aids. only recently have institutions begun to digitize their stamp collections and make the collections available for online review, as digitization in general has become more common in cultural heritage institutions. megan ozeran (megan.ozeran@gmail.com), a recent mlis degree graduate from san jose state university school of information, is winner of the 2017 lita/ex libris student writing award. managing metadata for philatelic materials | ozeran | doi:10.6017/ital.v36i3.10022 8 problem statement textual materials have received much attention in regards to digitization, including the creation and implementation of metadata standards and schemas. philatelic materials are not like textual materials, and are not even like photographic materials, which have also received some digitization attention. in fact, there is very little literature that currently exists describing how metadata is or should be applied to philatelic materials, even though digital collections of these materials already exist. therefore, the goal of this paper is to examine exactly how metadata is applied to digital collections of philatelic materials. several related questions drove the research about this topic: as institutions digitize stamp collections, what metadata schema(s) are they using to do so? are current metadata standards and schemas appropriate for these collections, or have institutions created localized versions? what metadata elements are most crucial in describing philatelic materials to enhance access in a digital collection? literature review while there is abundant literature regarding the use of metadata for library, archives, and museum collections, there is a dearth of literature that specifically discusses the use of metadata for philatelic materials. indeed, there is no literature at all that analyzes best practices for philatelic metadata, despite the fact that several large institutions have already created digital stamp collections. even among the many metadata standards that have been created, very few specify metadata guidelines for philatelic collections. it is clear that philatelic collections have not been highlighted in discussions over the last few decades about digitization, so best practices must be inferred based on the more general discussions that have taken place. the purpose and quality of metadata when considering why metadata is important to digital collections (of any type), it is crucial to remember, as david bade (2008) puts it, “users of the library do not need bibliographic records at all. . .. what they want is to find what they are looking for” (125). in other words, the descriptive metadata in a digital record is important only to the extent that it facilitates the discovery of materials that are useful to a researcher. as arms and arms (2004) point out, “most searching and browsing is done by the end users themselves. information discovery services can no longer assume that users are trained in the nuances of cataloging standards and complex search syntaxes” (236). echoing these sentiments, chan and zeng (2006) write, “users should not have to know or understand the methods used to describe and represent the contents of the digital collection” (under “introduction”). when creating digital records, then, institutions need to consider how the creation, display, and organization of metadata (especially within the search system) make it easier or more difficult for those end users to effectively search the digital collection. how effective metadata is in facilitating user research is ultimately dependent upon the quality of that metadata. bade (2007) notes that the information systems are essentially a way for an institution to communicate with researchers, and that this communication is only effective if metadata creators understand what the end users are looking for in the content and style of information technology and libraries | september 2017 9 communication (3-4). thus, in somewhat circular fashion, metadata quality is dependent upon understanding how best to communicate with end users. to help define discussions of metadata quality, bruce and hillmann (2004) suggest seven factors to consider: “completeness, accuracy, provenance, conformance to expectations, logical consistency and coherence, timeliness, and accessibility” (243). deciding how to prioritize one or several factors over the others will depend on the resources and goals of the institution, as well as the ultimate needs of the end users. the state of standards standards are created by various organizations to define the rules for applying metadata to certain materials in certain settings. standards generally describe a metadata schema, “a formal structure designed to identify the knowledge structure of a given discipline and to link that structure to the information of the discipline through the creation of an information system that will assist the identification, discovery and use of information within that discipline” (cc:da 2000, under “charge #3”). essentially, a metadata schema standard demonstrates how best to organize and identify materials to enhance discovery and use of those materials. such standards are helpful to catalogers and digitizers because they define rules for how to include content, how represent content, and/or what the allowable content values are (chan and zeng 2006, under “metadata schema”). unfortunately, very few current metadata standards even mention philatelic materials, despite their unique nature. the only standard that appears to do so with any real purpose is the canadian rules for archival description (rad), created by the bureau of canadian archivists in 1990, and revised in 2008. thirteen chapters comprise the first part of the rad, and these chapters describe the standards for a variety of media. philatelic materials are given their own focus in chapter 12, which discusses general rules for philatelic description as well as specifics for each of nine areas of description: title and statement of responsibility, edition, issue data, dates of creation and publication, physical description, publisher’s series, archival description, note, and standard number. the rad therefore provides a decent set of guidelines for describing philatelic materials. the encoded archival description tag library created by the society of american archivists (ead3, updated in 2015) mentions philatelic materials only in passing. there is no specific section discussing how to properly apply descriptive metadata to philatelic materials. the single mention of such materials in the entire ead3 documentation is in the discussion of the <materialspec> tag, where it is noted that “jurisdictional and denominational data for philatelic records” (257) may be recorded. other standards don’t appear to mention philatelic materials at all, so implementers of those standards must extrapolate based on the general information provided. for example, describing archives: a content standard (dacs), also published by the society of american archivists (2013), does not discuss philatelic materials in any way. it does note, “different media of course require different rules to describe their particular characteristics…” (xvii), but the recommendations for specific content standards for different media listed in appendix b still leave out philately (141142). institutions using dacs for philatelic materials need to determine how to localize the standard. although marc similarly does not include specific guidelines for philatelic materials, peter roberts (2007) suggests ways to effectively use it for cataloging philatelic materials. for managing metadata for philatelic materials | ozeran | doi:10.6017/ital.v36i3.10022 10 instance, in the marc 655 field he suggests using the getty art and architecture thesaurus terms to describe the form of the materials and the library of congress subject headings to describe the subjects (genres) of the materials (86-87). in similar ways, most standards could potentially be applied to philatelic materials if an institution were to provide additional local rules for how to best implement the standard. the metadata that philatelists want there are actually a good number of resources for determining what metadata is important to philatelic researchers. boggs (1955) suggests that a philatelist may want to “study the methods of production; the origin, selection, and the subject matter of designs; their relation to the social, political and economic history of the country of issue; the history of the postal service which issued them” (1-2). these few initial research suggestions can provide some insight into what metadata elements would be most useful in a digital record. david straight (1994) suggests the most basic crucial items are the date and country of issue for an item (75). roberts (2007) provides significant background about philatelic materials and research, and indicates multiple metadata elements that will be helpful for researchers. he reiterates that dates are extremely useful, and are often identified on the materials themselves; when specific dates are not visible, a stamp itself may provide evidence of an approximate year based on when the stamp was issued (75). he notes that many of the postal markings also “indicate the time and place of origin, route, destination, and mode of transportation” (78), which will also be of interest to philatelic researchers. if any information is available about the original collector, dealer, or exhibitor of the stamp before it was acquired by a cultural heritage institution, this may also be of great interest to a researcher (81). roberts also suggests that the finding aids for philatelic collections are more crucial places for description than for specific item records, and that controlled vocabulary subject terms are important in these descriptions (86). because the scott postage stamp catalogue is the leading united states authority on stamps, it can also suggest the metadata elements that primarily concern philatelic researchers. each listing includes a unique scott number, paper color, variety (e.g., perforation differences), basic information, denomination, color of the stamp, year of issue, value used/unused, any changes in the basic set information, and the total value of the set (scott publishing co. 2014, 14a). the scott catalogue also describes a variety of additional components that researchers may be interested in, including the type of paper used, any watermarks, inks used, separation type, printing process used, luminescence, and gum condition (19a-25a). one additional interesting source for deciding what metadata is important to researchers (aside from directly surveying them, of course) is a piece of software that was created to help philatelists catalog their own private collections. stampmanage is available in united states and international versions, and it is largely based on the scott postage stamp catalogue in creating the full listing of stamps that may be available to a collector. it includes a wide variety of metadata elements for cataloging stamps, such as the scott number, country of origin, date of issue, location of issue, type of stamp, denomination, condition, color, brief description, presence and type of perforations, category, plate block size, mint sheet size, paper type, presence and type of watermark, gum type, and so forth (liberty street software 2016). as a product that is sold to stamp collectors, information technology and libraries | september 2017 11 stampmanage is likely to have a confident grasp of all the metadata that could possibly be important to its customers. this literature review helps create a holistic view of the issues faced by cultural heritage institutions with digitized stamp collections. although little progress has been made in the literature to describe how best to apply metadata to philatelic materials, there are ways that institutions can extrapolate guidelines from the literature that does exist. methodology to explore my research questions, i interviewed (over email) representatives of several large institutions with digitized stamp collections. the information provided by these institutions sheds light on the current state of metadata and metadata schemas for philatelic collections. note that there are other institutions with online collections of postage stamps that are not discussed in this paper (e.g., the swedish postal museum, https://digitaltmuseum.se/owners/s-pm). due to my own language limitations, this paper is limited to analysis of online collections that are described in english. additional research into institutions with non-english displays would support greater analysis of how cultural heritage institutions are currently creating and providing philatelic metadata. results smithsonian national postal museum in the united states, the largest publicly accessible digital collection of philatelic materials is from the smithsonian national postal museum. i discussed the metadata for this collection with elizabeth heydt, collections manager at the museum. ms. heydt stated that the stamps are primarily identified “by their country and their scott number” (e. heydt, pers. comm., october 5, 2016). for digital collections, the smithsonian national postal museum uses a gallery systems database called the museum system, which includes the getty art and architecture thesaurus as an embedded thesaurus. ms. heydt noted that aside from this embedded thesaurus, they “do not use any additional, formalized data standards such as the dublin core, mods,” or the like. of note, the museum system does allege compliance with “standards including spectrum, cco, cdwa, dacs, chin, lido, xmp, and other international standards” (gallery systems 2015, 4). the end user interface that pulls data from the museum system is called arago, which has “an internal structure that built on the scott catalogue system and some internal choices for grouping and classifying objects for the philatelic and the postal history collections.” users can search and browse the entire digital collection through arago, but ms. heydt did note that arago “is in stasis right now as we are in the planning stages for an updated version sometime in the near future.” based on an example record (http://arago.si.edu/record_145471_img_1.html), the descriptive metadata currently available for end users include a title, scott number, detailed description (including keywords), date of issue, medium, museum id (a unique identifier), and place of origin. digital images of the stamps are also included. a set of “breadcrumb” links at the top of the page also allow a user to browse each level of the digital collection, from an individual stamp record up to the entire museum collection as a whole. managing metadata for philatelic materials | ozeran | doi:10.6017/ital.v36i3.10022 12 library and archives canada i discussed the library and archives canada (lac) online philatelic collection with james bone, archivist at the lac. he explained that the philatelic collection has had a complicated history: our philatelic collection largely began with the dissolution of the national postal museum … in 1989 and the subsequent division and transfer of its collection to the canadian postal museum for artifacts/objects at the former canadian museum of civilization (now the canadian museum of history) and to the canadian postal archives at the former national archives (which was merged with the national library in the mid-2000s to create library and archives canada). as a side note, both the canadian postal museum and the canadian postal archives are themselves now defunct – although lac still acquires philatelic records and records related to philately and postal administration, these functions are no longer handled by a dedicated section but rather by archivists within our government records branch and our private records branch (the latter being me). (j. bone, pers. comm., october 11, 2016) regarding the collection’s metadata, mr. bone confirmed that the archival records at the lac all conform to the rad standard (discussed in the literature review above), and that philatelic materials are all given “at least a minimum level of useful file level or item level description for philatelic records based on chapter 12 of rad,” the chapter that specifically discusses philatelic materials. unfortunately, to his knowledge, the online database for these records does not use a common metadata standard such as oai-pmh that enables “external metadata harvesting or querying,” so the system is not searchable outside of the lac website. mr. bone also pointed out that there are fields visible on the back end of the lac online database that are not visible to end users, and the most notable of these omissions is the scott number (the number assigned to every stamp by the scott catalogue). he wrote that it seemed “bizarre” to not have the scott number visible, “as that’s definitely an access point that i would expect philatelic researchers to use to narrow down a result set to the postage stamp issue of interest.” however, it appears this invisibility was a decision consciously made by the lac, based on mr. bone’s review of an internal lac standards document. based on an example record (http://collectionscanada.gc.ca/pam_archives/index.php?fuseaction=genitem.displayitem&lang= eng&rec_nbr=2184475) the following fields are available for end users to view: title, place of origin, denomination, date of issue, title of the collection of which it is a part, extent of item, language, access conditions, terms of use, mikan number (a unique identifier), itemlev number (deprecated), and any additional relevant information such as previous exhibitions of the physical item. the postal museum the postal museum in london is set to open its physical doors in 2017, but much of the collection is already available for browsing and searching online. stuart aitken, curator, philately, explained to me that the online collection uses the general international standard archival description, second edition, as the primary metadata schema, but the online collection also includes “non isad(g) fields for certain extra-specific data for our archive material, including philatelic material” (s. aitken, pers. comm., december 1, 2016). based on my own review of the isad(g) standards information technology and libraries | september 2017 13 document (international council on archives 1999) and an example record from the postal museum’s online collection (http://catalogue.postalmuseum.org/collections/getrecord/gb813_p_150_06_02_011_01_001#cu rrent), it appears nearly all the fields are based on the isad(g) standards. these fields include information such as date, level of description, extent of item, language, description, and conditions for access and reproduction. only the field for “philatelic number” appears to be extra. there may be additional non-isad(g) fields that are not included in the example record above, but are included in other records when the extra information is available and relevant. each digital record also allows end users to submit tags for help with identification and search. no tags were already submitted on the example record reviewed above, but this is likely because the online collection is still rather new. of note, digital records are created at each archival level, from the broadest collection category down to the individual item (similar to the smithsonian national postal museum collection). to provide an additional way to browse the collection, a sidebar in each digital record shows where it exists in the hierarchy of collections and provides links to each broader collection of which the current record is a part. the british museum i reached out to the folks at the british museum to discuss the application of metadata to their online records for postage stamps, but at the time of this writing i have not received any response. however, some information can be gleaned from examining the website. unlike the other institutions reviewed in this paper, the british museum’s online collection includes a wide variety of objects. postage stamps are therefore identified in the online collection by specifying “postagestamp” in the “object type” field, which likely uses a controlled vocabulary. based on an example record (http://www.britishmuseum.org/research/collection_online/collection_object_details.aspx?objec tid=1102502&partid=1&searchtext=postage+stamp&page=1), each record for a postage stamp lists the museum number (a unique identifier), denomination, description, date issued, country of origin, materials, dimensions, acquisition name and date, department, and registration number (which appears to be the same as the museum number). digital images of the stamps are occasionally included. the collection website notes that the british museum is “continuing every day to improve the information recorded in it [the digital collection] and changes are being fed through on a regular basis. in many cases it does not yet represent the best available knowledge about the objects” (trustees of the british museum 2016a, under “about these records”). therefore, end users are encouraged to read the information in any given record with care, and to provide feedback if they have any additional information or corrections about an object. the online collection also is offered in machine-readable format, via linked data and sparql, to encourage wider accessibility and use. the website advises, the use of the w3c open data standard, rdf, allows the museum's collection data to join and relate to a growing body of linked data published by other organisations around the world interested in promoting accessibility and collaboration. the data has also been organised using the cidoc crm (conceptual reference model) crucial for harmonising managing metadata for philatelic materials | ozeran | doi:10.6017/ital.v36i3.10022 14 with other cultural heritage data. the cidoc crm represents british museum's data completely and, unlike other standards that fit data into a common set of data fields, all of the meaning contained in the museum's source data is retained. (trustees of the british museum 2016b) each digital object has rdf and html resources, as well as a sparql endpoint with an html user interface. discussion the information from the four institutions above provides a starting point for examining best practices for philatelic metadata. in the following discussion, i will review the information in light of the research questions: important metadata elements, the standards that were implemented, and whether the standards that currently exist have been sufficient. as explained in the literature review above, relevant metadata are crucial for enhancing end user research of digital records. this suggests that similarity of metadata across collections of the same type will improve users’ ability to conduct their research. unfortunately, there are only a few descriptive metadata fields used across all four of the institutions reviewed in this paper. these fields include a title (sometimes used very loosely), the date of issue, the place of issue, a description, and a unique identifier. these fields certainly seem to be the absolute minimum necessary for identifying (and searching for) a postage stamp, since they are among the fields discussed in the literature review as being important to philatelic researchers. other fields that are included in some but not all of the above collections, such as stamp denomination and access conditions, are nonetheless quite relevant to online collections of postage stamps. interestingly, although the scott catalogue is recognized as a premier stamp catalogue, only one institution (the smithsonian national postal museum) currently uses the scott identification number as part of the standard philatelic metadata. as noted above, the library and archives canada does include the scott number in the behind-the-scenes metadata, but does it not display the scott number to end users. the postal museum and the british museum don’t use the scott number at all. it appears that only the smithsonian believes the scott number is useful to end users, either for search or identification purposes. of the four institutions, it appears that only the british museum uses metadata standards that increase the accessibility of the online collection beyond its own website. the implementation of rdf for linked data creates an open collection that is machine-readable beyond the internal database used by the museum. the smithsonian national postal museum, library and archives canada, and the postal museum do not appear to use any similar metadata standard for data harvesting or transmission, which means that these collections can only be searched from within their respective websites. the most important thing to note in reviewing the online collections for these four institutions is the fact that each institution uses different standards to apply metadata in a different way. frankly, this is not a surprise. as discussed in the literature review above, although metadata standards exist for a variety of materials, philatelic materials are simply not considered. only the canadian rules for archival description explicitly include information about philatelic materials; information technology and libraries | september 2017 15 accordingly, the library and archives canada utilizes these rules when creating its online records of postage stamps. no similar standard exists in the united states or internationally, leaving individual institutions with the task of deciding what generic metadata standard to use as a jumping off point, and then modifying it to meet local needs. as described above, the smithsonian national postal museum uses the metadata schema that comes with their collection management software, and has created an end-user interface based off of internal metadata decisions. the postal museum based their metadata primarily off of isad(g), an international metadata standard with no specific suggestions for philatelic materials. i was unable to confirm the base metadata schema the british museum employs, although it is clear they use rdf to make the collection’s digital records more widely available. each institution appears to be using a different base metadata standard, essentially requiring them to reinvent the wheel upon deciding to digitize philatelic materials. this is what happens when there is no single, unified standard available for the type of material being described. conclusion as this paper has shown, metadata standards are sorely lacking when it comes to philatelic materials. other kinds of materials have received special considerations because more and more institutions decided it would be important to digitize them, so various groups came together to create standards that provide some guidance. it is time for this to happen for philatelic materials as well. there aren’t many cultural heritage institutions that currently manage digital collections of philatelic materials, so this is an opportunity for those who plan to digitize their collections to consider what has been done and what makes sense to pursue. it is clear that philatelic digitization is still nascent, but as with other kinds of materials, it is only likely that more and more institutions will attempt digitization projects. it is hoped that this paper can serve as a jumping off point for institutions to discuss the creation of international metadata standards specifically for philatelic materials. acknowledgements many thanks are owed to the people who took time out of their very busy lives to respond to the unrefined inquiries of an mlis grad student: stuart aitken (curator, philately, the postal museum); james bone (archivist, private archives branch, library and archives canada); and elizabeth heydt (collections manager, smithsonian national postal museum). their expertise and responsiveness is immensely appreciated. managing metadata for philatelic materials | ozeran |

the university of nevada las vegas libraries’ focus on the concept of discovery and the tools and processes that enable our users to find information began with an organizational review of the libraries’ technical services division. this article outlines the phases of this review and subsequent planning and organizational commitment to discovery. using the theoretical lens of organizational learning, it highlights how the emerging focus on discovery has provided an impetus for genuine learning and change. t he university of nevada las vegas (unlv) libraries’ focus on the concept of discovery and the tools and processes that enable our users to find information stemmed from the confluence of several initiatives. however, a significant path that is directly responsible for the increased attention on discovery leads through one unit in unlv libraries—technical services. this unit, consisting of the materials ordering and receiving (acquisitions) and bibliographic and metadata services (cataloging) departments, had been without a permanent director for three years when i was asked to take the interim post in april 2008. while the initial expectation was that i would work with the staff to continue to keep technical services functioning while we performed our third search for a permanent director, it became clear after three months that, because of nevada’s budgetary limitations, we would not be able to go forward with a search at that time. as all personnel searches in unlv libraries were frozen, managers and staff across the divisions moved quickly to reassign staff with the aim of mitigating the effects of staff vacancies. there was division between the library administrators as to what the solution would be for technical services: split up the division—for which we had trouble recruiting and retaining a leader in the past—and divvy up its functions among other divisions in the libraries, or to continue to hold down the fort while conducting a review of technical services that would inform what it might become in the future. other organizations have taken serious looks at, and provided roadmaps of, how their organizations’ focus of technical services will change in the future.1 the latter route was chosen, and the review—eventually dubbed revisioning technical services—led directly to the inquiries and activities documented in this ital special issue. detailing the process of revisioning technical services and using the theoretical lens of organizational learning, i will demonstrate how the libraries’ emerging focus on the concept of discovery has provided an impetus for genuine learning and change. n organizational learning in images of organization, morgan devotes a chapter to theories of organizational development that characterize organizations using the metaphor of the brain.2 based on the principles of modern cybernetics, argyris and schön provide a framework for thinking about how organizations can learn to learn.3 while many organizations have become adept at single-loop learning—the ability to scan the environment, set objectives, and monitor their own figure 1. singleand double-loop learning source: learning-org discussion pages, “single and double loop learning,” learning-org dialog on learning organizations, http://www.learning-org.com/ graphics/lo23374singledll.jpg (accessed aug. 11, 2009). jennifer l. fabbi (jennifer.fabbi@unlv.edu) is special assistant to the dean at the university of nevada las vegas libraries. “discovery” focus as impetus for organizational learning | fabbi 165 general performance in relation to existing operating norms—these types of systems are generally designed to keep the organization “on course.” double-loop learning, on the other hand, is a process of learning to learn, which depends on being able to take a “double look” at the situation by questioning the relevance of operating norms (see figure 1). bureaucratized organizations have fundamental organizing principles, including management hierarchy and subunit goals that are seen as ends to themselves, which can actually obstruct the learning process. to become skilled in the art of double-loop learning, organizations must avoid getting trapped in singlelooped processes, especially those created by “traditional management control systems” and the “defensive routines” of organizational members.4 according to morgan, cybernetics suggests that learning organizations must develop capacities that allow them to do the following:5 n scan and anticipate change in the wider environment to detect significant variations by o embracing views of potential futures as well as of the present and the past; o understanding products and services from the customer’s point of view; and o using, embracing, and creating uncertainty as a resource for new patterns of development. n develop an ability to question, challenge, and change operating norms and assumptions by o challenging how they see and think about organizational reality using different templates and mental models; o making sure strategic development does not run ahead of organizational reality; and o developing a culture that supports change and risk taking. n allow an appropriate strategic direction and pattern of organization to emerge by o developing a sense of vision, norms, values, limits, or “reference points” to guide behavior, including the ability to question the limits being imposed; o absorbing the basic philosophy that will guide appropriate objectives and behaviors in any situation; and o placing as much importance on the selection of the limits to be placed on behavior as on the active pursuit of desired goals. unlv libraries’ revisioning technical services process and the resulting organizational focus on discovery is outlined below, and the elements identifying unlv libraries as a learning organization throughout this process are highlighted (see appendix a). n revisioning technical services this review of technical services was a process consisting of several distinct steps over many months, and each step was informed by the data and opinions gained in the prior steps: phase 1: technical services baseline, focusing on the nature of technical services work at unlv libraries, in the library profession, and factors that affect this work now and in the future phase 2: organizational call to action, engaging the entire organization in shared learning and input phase 3: summit on discovery, shifting significantly away from technical services and toward the concept of discovery of information and the experience of our users technical services baseline the first phase of the process, which i called the “technical services baseline,” included a face-to-face meeting with me and all technical services staff. we talked openly about the challenges that we faced, options on the table for the division and why i thought that taking on this review would be the best course to pursue, and goals of the review. outcomes of the process were guided by the dean of libraries, were written by me, and received input from technical services staff, resulting in the following goals: 1. collect input about the kinds of skills and leadership we would like to see in our new technical services director. (while creating these goals, we were given the go-ahead to continue our search for a new director). 2. investigate the organization of knowledge at a broad level—what is the added value that libraries provide? 3. increase overall knowledge of professional issues in technical services and what is most meaningful for us at unlv. 4. encourage technical services staff to consider current and future priorities. after establishing these goals, i began to document information about the process on unlv libraries’ staff website (figure 2) so that all staff could follow its progress. 166 information technology and libraries | december 2009 with the feedback i received at the face-to-face meeting and guided by the stated goals of the process, i gave technical services staff a series of three questions to answer individually: 1. what do you think the major functions of technical services are? examples are “cataloging physical materials” and “ordering and paying for all resources purchased from the collections budget.” 2. what external factors—in librarianship and otherwise—should we be paying the most attention to in terms of their effect on technical services work? examples are “the ways that users look for information” and “reduction of print book and serials budgets.” feel free to do a little research on this question and provide the sources of the information that you find. 3. what are the three highest priority/most important tasks on your to-do list right now? eighteen of twenty staff members responded to the questions. i then analyzed the twenty pages of feedback according to two specific criteria: (1) i paid special attention to phrases that indicated an individual’s beliefs, values, or philosophies to identify potential sources of conflict as we moved through the process; and (2) i looked for priority tasks listed that are not directly related to the individual’s job duties, as many of them were indicators of work stress or anxiety related to perceived impending change. during this phase, organizational learning was initiated through the process of challenging how technical services staff and others viewed technical services as a unit in the organization, and through the creation of shared reference points to guide our future actions. while beginning a dialogue about a variety of future management options for technical services work functions may have raised levels of anxiety within the organization, it also invited administration and staff to question the status quo and consider alternative modes of operation within the context of efficiency.6 in addition to thinking about current realities and external influences, staff were asked to participate in generating outcomes to guide the review process. these shared goals helped to develop a sense of coherence for what started out as a very loose assignment—a review that would inform what the unit might become in the future. organizational call to action the next phase of the process, “a call to action,” required library-wide involvement and input. while i knew that this phase would involve a library staff survey, i also desired that all staff responding to the survey had a basic knowledge of some of the issues that are facing library technical services today. using input from the two technical services department heads, i selected two readings for all library staff: bothmann and holmberg’s chapter on strategic planning for electronic resource management addressed many of the planning, policy, and workflow issues that unlv libraries has experienced7; and coyle’s article on information organization and the future of the library catalog offers several ideas for ensuring that valuable information is visible to our users in the information environments they are using.8 i also asked the library staff to visit the university of nebraska–lincoln’s “encore catalog search” (http://iris.unl.edu) and go through the discovery experience by performing a guided search and a search on a topic of their choice. they were then asked to ponder what collections of physical or digital resources we currently own at the libraries that are not available from the library catalog. after completing these steps, i directed library staff to a survey of questions related to the importance of several items referenced in the articles in terms of the following unlv libraries priorities: n creating a single search interface for users pulling together information from the traditional library catalog as well as other resources (e.g., journal articles, images, archival materials) n considering non–marc records in the library catalog for the integration of nontraditional library and nonlibrary resources into the catalog n linking to access points for full-text resources from the catalog n creating ways for the catalog to recommend items to users figure 2. project’s wiki page on staff website “discovery” focus as impetus for organizational learning | fabbi 167 n creating metadata for materials not found in the catalog n creating “community” within the library catalog n implementing an electronic resource management system (erms) to help manage the details related to subscriptions to electronic content n implementing federated searching so that users can search across multiple electronic resource interfaces at once n making electronic resource license information available to library staff and patrons there also were several questions asking library staff to prioritize many of the functions that technical services already undertakes to some extent: n cataloging specialized or unique materials n cataloging and processing gift collections n ensuring that full-text electronic access is represented accurately in the catalog n claiming and binding print serials n ordering and receiving physical resources n ordering and receiving electronic resources n maintaining and communicating acquisitions budget and serials data the survey asked technical services staff to “think of your current top three priority to-do items. in light of what you read and what you think is important for us to focus on, how do you think your work now will have changed in five years?” all other library staff members were asked to respond to the following: 1. please list two ways that technical services supports your work now. 2. please list two things you would like technical services to start doing in support of your work now. 3. please list two things you think technical services can stop doing now. 4. please list two things technical services will need to begin doing to support your work in the next five years. finally, the survey included ample opportunity for additional comments. fifty-eight staff members (over half of all library staff) completed the readings, activity, and survey. i analyzed the information to inform the design of subsequent phases of revisioning technical services. the dean of libraries’ direct reports then reviewed the design. in addition, many library staff contributed additional readings and links to library catalogs and other websites to add to the revisioning technical services staff webpage. throughout this phase, the organization was invited into the learning process through engagement with shared reference points, the ability to question the status quo, and the ability to embrace views of potential futures as well as of the present and the past.9 the careful selection of shared readings and activities created coherence among the staff in terms of thinking about the future, but these ideas also raised many questions about the concept of discovery and what route unlv libraries might take. the survey allowed library staff to better understand current practices in technical services, to prioritize new ideas against these practices, and to think about future options and their potential impact on their individual work as well as the collective work of the libraries. summit on discovery in the third phase of this process, “the discovery summit,” focus began to shift significantly from technical services as an organizational unit to the concept of discovery and what it means for the future of unlv libraries. during this half-day event, employing a facilitator from off campus, the dean of libraries and i designed a program to fulfill the following desired outcome: through a process of focused inquiry, observation, and discussion, participants will more fully understand the discovery experience of unlv libraries users. the event was open to all library staff members; however, individuals were required to rsvp and complete an activity before the day of the event. (the facilitator worked specifically with the technical services staff at a retreat designed to prepare for upcoming interviews for technical services director candidates.) participants were each sent a “summit matrix” (see appendix b) ahead of time, which asked them to look for specific pieces of information by doing the following: 1. search for the information requested with three discovery tools as your starting points: the libraries’ catalog, the libraries’ website, and a general internet search engine (like google). 2. for each discovery tool, rate the information that you were able to find in terms of “ease of discovery” on a scale of 1 (lowest ease—few results) to 5 (highest ease—best results). 3. document the thoughts and feelings you had and/ or process you went through in searching for this information. 4. answer this question: do you have other preferred starting points when looking for information that the libraries own or provide access to? the information that staff members were asked to search for using each discovery tool was mostly specific to the region of southern nevada, such as, “i heard that henderson (a city in southern nevada) started as a mining community. does unlv libraries have any books about that?” and “find any photograph of the gay 168 information technology and libraries | december 2009 pride parade in las vegas that you can look at in unlv libraries.” during the summit, the approximately sixty participants were asked to discuss their experiences searching for the matrix information, including any affective component to their experience, and they were asked to specify criteria for their definition of “ease of discovery.” next, we showed end-user usability video testing footage of a unlv professor, a human resources employee, and a unlv librarian going through similar discovery exercises. after each video, we discussed these users’ experiences—their successes, failures, and frustrations— and the fact that even our experts were unable to discover some of this information. finally, we facilitated a robust brainstorming session on initiatives we could undertake to improve the discovery experience of our users. [editor’s note: read more about this usability testing in “usability as a method for assessing discovery” on page 181 of this issue.] during the wrap-up of the discovery summit, the final phase of this initial process, the discovery miniconference was introduced. a call for proposals for library staff to introduce or otherwise present discovery concepts to other library staff was distributed. this call tied together the revisioning technical services process to date and also placed the focus on discovery to the libraries’ upcoming strategic planning process. this strategic planning process, outlining broad directions for the libraries to focus on for the next two years, would be the first time we would use our newly created evaluation framework. we focused on the concepts of discovery, access, and use, all tied together through an emphasis on the user. all library staff members were invited to submit a poster session or other visual display on various themes related to discovery of information to add to our collective and individual knowledge bases and to better understand our colleagues’ philosophies and positions on discovery. in addressing one of six mini-conference themes listed below, all drawn directly from the revisioning technical services survey results, potential participants were asked to consider the question, “what are your ideas for ways to improve how users find library resources?” n single search interface (federated searching, harvester-type platform, etc.) n open source vs. vendor infrastructure n information-seeking behavior of different users n social networking and web 2.0 features as related to discovery n describing primary sources and other unique materials for discovery n opening the library catalog for different record types and materials proposals could include any of these perspectives: n an environmental scan with a summary of what you learn n a visual representation of what you would consider improvement or success n a position for a specific approach or solution that you advocate ultimately, we had seventeen distinct projects involving twenty-four staff members for the afternoon miniconference. it was attended by approximately seventy additional staff members from unlv libraries as well as representatives from institutions who share our innovative system. we collected feedback on each project in written form and electronically after the mini-conference. miniconference content was documented on its own wiki pages and in this special issue of ital. during this phase of the revisioning technical services process, there was an emphasis on understanding our services from the customers’ point of view, a hallmark of a learning organization.10 during the discovery summit, we aimed to transform frustration and uncertainty over the user experience of the services we are providing into a motivation to embrace potential futures. the mini-conference utilized the discovery themes that had evolved throughout the revisioning technical services process to provide a cohesive framework for library staff members to share their knowledge and ideas about discovery systems and to question the status quo. n organizational ownership of discovery: strategic planning and beyond through the phases of the revisioning technical services process outlined above, it should be evident how the concept of discovery, highlighted during the process, moved from being focused on technical services to being owned by the entire organization. while the vocabulary of discovery had previously been owned by pockets of staff throughout unlv libraries, it has now become a common lexicon for all. the libraries’ evaluation framework, which includes discovery, had set the stage for our upcoming organizational strategic plan. just prior to the discovery summit, the dean of libraries’ direct reports group began to discuss how it would create a strategic plan for the 2009–11 biennium. it became increasingly apparent how important a focus on discovery would be in this process, and that we needed to time our planning right, allowing the organization and ourselves time to become familiar with the potential activities we might commit to in this area before locking into a strategic plan. “discovery” focus as impetus for organizational learning | fabbi 169 the dean’s direct reports group first spent time crafting a series of strategic directions to focus on in the two-year time period we were planning for. rather than give the organization specific activities to undertake, the strategic directions were meant to focus our new initiatives—and in a way to limit that activity to those that would move us past the status quo. of the sixteen directions, one stemmed directly from the organization’s focus on discovery: “improve discoverability of physical and electronic resources in empowering users to be self sufficient; work toward an interface and system architecture that incorporates our resources, internal and external, and allows the user to access them from their preferred starting point.” an additional direction also touched on the discovery concept: “monitor and adapt physical and virtual spaces to ensure they respond to and are informed by next-generation technologies, user expectations, and patterns in learning, social interactions, and research collaboration; encourage staff to experiment with, explore, and share innovative and creative applications of technology.” through their division directors and standing committees, all library staff members were subsequently given the opportunity to submit action items to the strategic plan within the framework of the strategic directions. the effort was made by the dean of libraries for this part of the process to coincide with the discovery mini-conference, a time when many library staff members were being exposed to a wide variety of potential activities that we might take as an organization in this area. one of the major action items that made it into the strategic plan was for the dean’s direct reports to charge an oversight task force with the investigation and recommendation of a systems or systems that would foster increased, unified discovery of library collections. the charge of this newly created discovery task force includes a set of guiding principles for the group in recommending a discovery solution that n creates a unified search interface for users pulling together information from the library catalog as well as other resources (e.g., journal articles, images, archival materials); n enhances discoverability of as broad a spectrum of library resources as possible; n is intuitive: minimizes the skills, time, and effort needed by our users to discover resources; n supports a high level of local customization (such as accommodating branding and usability considerations); n supports a high level of interoperability (easily connecting and exchanging data with other systems that are part of our information infrastructure); n demonstrates commitment to sustainability and future enhancements; and n is informed by preferred starting points of the user. in setting forth these guiding principles, the work of the discovery task force is informed by the organization’s discovery values, which have evolved over a year of organizational learning. in the timing of the strategic planning process and the emphasis of the plan, we made sure that the organization’s strategic development did not run ahead of organizational reality and also have worked to develop a culture that supports change and risk taking.11 the strategic discovery direction and pattern of organizational focus has been allowed to emerge throughout the organizational learning process. as evidenced in both the strategic plan directions and guiding principles laid out in the charge of the discovery task force, the organization has begun to absorb the basic philosophy that will guide appropriate objectives in this area and has focused more on this guiding philosophy than on the active pursuit of one right answer as it continues to learn. n conclusion using the theoretical lens of organizational learning, i have documented how unlv libraries’ emerging focus on the concept of discovery has provided an impetus for learning and change (see appendix a). our experience throughout this process supports the theory that organizational intelligence evolves over time and in reference to current operating norms.12 argyris and schön warn that a top-down approach to management focusing on control and clearly defined objectives encourages singleloop learning.13 had unlv libraries chosen a more management-oriented route at the beginning of this process, it most likely would have yielded an entirely different result. in this case, genuine organizational learning proved to be action based and ever-emerging, and while this is known to introduce some level of anxiety into an organization, the development of the ability to question, challenge, and potentially change operating norms has been worth the cost.14 i believe that while any single idea we have broached in the discovery arena may not be completely unique, it is the entire process of organizational learning that is significant and applicable to many information and technology-related areas of interest. references 1. karen calhoun, the changing nature of the catalog and its integration with other discovery tools (washington, d.c.: library 170 information technology and libraries |

memphis article redesigning research guides lessons learned from usability testing at the university of memphis jessica mcclure, carl hess, and david marsicano information technology and libraries | september 2023 https://doi.org/10.5860/ital.v42i3.15535 jessica mcclure (jmcclre3@memphis.edu) is the virtual instruction librarian, university of memphis. carl hess (carl.hess@memphis.edu) is the undergraduate success librarian, university of memphis. david marsicano (dmmrscno@memphis.edu) is a library assistant ii, university of memphis. © 2023. abstract at the university of memphis, a team of librarians and library staff formed the research guides redesign team (rgrt) to redesign, organize, and evaluate the university libraries’ (ul) research guides. the purpose of the project was to ensure that the new design of the research guides homepage was intuitive to use. while it is impossible to ensure absolute usability for every user, this usability study attempts to eradicate the most common interface issues in community experiences at the university of memphis. the rgrt conducted usability testing to evaluate the effectiveness of the new standardized format, grouped headings, and the appearance of the interface. the rgrt worked within the limitations of springshare’s software to create the design and then chose five users to complete various task scenarios. upon analysis of the users’ ability to complete the tasks, the rgrt discovered that overall, the design was effective, but they did make a few minor changes. this study describes the process and includes the original design, the new design, edits made after usability testing was conducted, and plans for future testing. introduction in the spring of 2021, the research guides redesign team (rgrt) assembled to establish a new workflow for maintaining and designing research guides at the university of memphis. previously, all university library (ul) faculty (hereafter “librarians”) were tasked with creating and maintaining research guides for academic programs and courses in their liaison areas in addition to their other duties. all librarians took part in the liaison program but did not have extensive training in guide creation. as a result, many guides consisted of lists of resources without instructions on how to use them, did not encourage information-seeking behavior, or did not cover basic information literacy skills.1 while some librarians had administrative privilege over the research guides software (springshare’s libguides product), no one was tasked with reviewing or evaluating the guides holistically. consequently, librarians were creating guides for their liaison departments without considering whether the information they included was covered in existing guides, and many were not regularly updated. the rgrt was created to solve these issues. it allowed for a more centralized workflow for creating and maintaining guides. it comprised a smaller group of librarians and library staff volunteering to take the baton from library liaisons in creating, updating, and deleting guides based on the needs of all patrons at the university of memphis. the role of liaison librarians in the process changed to providing content expertise for their assigned departments’ guides as needed. mailto:jmcclre3@memphis.edu mailto:carl.hess@memphis.edu mailto:dmmrscno@memphis.edu information technology and libraries september 2023 redesigning research guides 2 mcclure, hess, and marsicano the rgrt selected the redesign of the research guides homepage as the first project. the homepage (illustrated in figs. 1, 2, and 3) had become an unwieldy list, organized by a mix of topic headings and headings reflecting university college and school names. users had to scroll through this list to find guides, which the rgrt decided was clunky and inefficient. there was a search bar for locating guides, but it was in the upper right of the page away from the guide list (see fig. 1–3). despite this long list of guides, users were often choosing between very similar guides with redundant content and long lists of undifferentiated resources, and if a u ser found a guide, it was not guaranteed to be up to date and often did not follow a consistent format. improving this experience became the focus of the rgrt. while the rgrt considered starting with usability testing on the old homepage, it determined this was not necessary. the guides included many of the common usability issues in libguides as described by thorngate and hoden including “inconsistent design from page to page and from guide to guide,” “cluttered pages lacking a focal point,” and “too much content, not appropriately scoped to the task at hand”; and anecdotally, librarians and staff in the past had expressed frustrations with trying to find useful guides to share with patrons while navigating through the clutter of the homepage.2 further, the rgrt began the project of homepage and guide redesign early in the covid-19 pandemic. this would have required recruiting and running usability testing remotely, since the campus was primarily engaging in virtual instruction, adding difficulty to the project. the pandemic virtual instruction environment also gave the rgrt an added sense of urgency to quickly design a more usable research guide environment, since the ul’s digital learning objects and digital services had become the primary tool for patrons to interact with the ul. performing virtual usability testing was a less efficient use of time when a wide variety of usability issues with the old setup was already known. the homepage redesign project took place simultaneously with a project to reorganize the subject guides, consolidate related academic programs to limit the amount of redundant content, focus more on teaching users how to use the resources recommended in the guides, and create a more manageable number of guides both for users and for the rgrt to update. all guides now have a consistent format and include instructional materials (videos, tutorials, etc.) to teach users how to use the resources in each guide. this study describes the creation and testing conducted on the new design of the r esearch guides homepage and the redesigned subject guides. to assess the success of the rgrt’s work on the new homepage, the researchers’ objectives for this study were to: • identify whether users could effectively navigate the new homepage structure, inclu ding categorization and search features. • determine whether the new structure allowed users to identify useful resources with a minimum of attempts and clicks. • demonstrate that the updated design facilitated and encouraged users’ informationseeking behavior. information technology and libraries

increase in the number of students attending classes online.3 this growth has implications for the use of library digital materials. a primary research group study of online library services revealed that 10 out of 37 academic libraries reported that distance students utilized research guides and tutorials more than traditional students.4 another stated the use of research guides increased by 56 percent in 2020.5 colorado christian university also used the covid-19 pandemic as an opportunity to redesign its websites and research guides.6 ghaphery and white’s study states that “libguides are as commonplace as books” in academic libraries, reiterating a need for gathering more usage statistics on them.7 based on this data, increasing the effectiveness and usefulness of these library digital materials is imperative to expand the scope of the library’s reach to all users, not just those on ground. it is clear research guides are one of the primary ways academic libraries share their resources with the community and that ongoing maintenance and attention is essential, particularly to online users. the authors of this study wanted to know how topic-based navigation would work for the university of memphis and wanted to conduct usability testing based on this design. the value of usability testing in libraries is well documented.8 at california state university, vargas discovered that using a topic-based navigation design is user-friendly and helps patrons “get used to” the site layout.9 furthermore, polger observed that the website and not the building is the user’s first interaction with the space and is often deemed the “face” of the library.10 designers of library web pages must organize information in a way that is intuitive for all users. this includes faculty, staff, undergraduate and graduate students, visiting researchers, and those with disabilities. while it is an impossible task to ensure absolute usability for every user, this usability study attempts to eradicate the most common interface issues in community experiences at the university of memphis. information technology and libraries september 2023 redesigning research guides 6 mcclure, hess, and marsicano redesigning research guides as a more holistic way of sharing resources with faculty and students is an effective way of designing. in the past, many research guides were lists of key reference sources; catalogs for finding books, theses, and dissertations; and periodical databases for finding journal articles and news articles—without much guidance on how to use them.11 similarly, the authors of a five-step usability study with research guides discovered that a significant challenge was that the “purpose and nature of research guides was not readily evident to users” and the library jargon used was confusing to users as well.12 an example of a more holistic design would be one guiding students through the research process.13 replacing library vocabulary with more commonly used language is also recommended.14 bowen et al. stated, “consequently, the questions of what to put on a guide and how best to arrange that material have driven an entire research agenda for the better part of a decade.” their study has similar objectives to this one regarding the ease of use and navigation menus. they elected to use an a/ b method of usability testing, presenting students with two different versions of the same page. their study was an excellent example of providing a format that would assist users with comprehending the content instead of having to understand the design itself.15 for this study, the rgrt adopted the five-user assumption commonly practiced among user experience professionals. the five-user assumption posits that, as you run usability testing, each additional user after the first will find usability problems already discovered by an earlier user in addition to discovering new problems. after the fifth user, the amount of repeat problems found will be so much greater than the number of new problems discovered as to render further testing an inefficient use of time and resources.16 borsci et al. addressed and tested the debate concerning the five-user assumption and its established adoption. they observed that, while it is widely accepted, human-computer interaction professionals are split into two camps: those who apply and accept the model and those who are critical of it but apply it nevertheless. they proposed an alternative model called the “grounded procedure,” but still recommended the five-user assumption as a starting point.17 additionally, the rgrt adopted the use of task scenarios for usability testing to gain valuable insights from users. rather than setting goals such as “find a website on citation,” it is more helpful to design a task that presents context. therefore, a task scenario lets the user know why they need to find something and not simply how. mccloskey recommended designing tasks based on what a user would realistically do when visiting the website. she recommended making the task “actionable” to set up the context of why a user would need to visit the site.18 the success of mccloskey’s recommended actionable tasks are observed in many other usability studies.19 redesign process to create the design, the rgrt began by independently investigating other universities ’ research guides homepage designs and reporting back to the group on their findings. the rgrt was looking for a model for improving categorization and guides, limiting the use of long lists, and foregrounding search. after investigating a few candidates, the group unanimously agreed that the university of arizona’s research guides homepage (see fig. 4) should be the model.20 the design was effective because the content was not excessive, scrolling was unnecessary, and headings were descriptive. the visual aspects were not purely decorative and helped the patron understand the purpose of the content. the rgrt was given approval from the university of arizona to model the new research guides homepage after theirs.21 in this model, a topic-based navigation design would organize sections into research help guides, subject guides, topic guides, and course guides. every guide would only be included in one of these four categories. research help guides covered information literacy and library use skills, subject guides covered major academic https://libguides.library.arizona.edu/library-guides information technology and libraries september 2023 redesigning research guides 7 mcclure, hess, and marsicano programs, and course guides were for specific classes. topic guides was a catch -all area for guides that did not easily fit in the other categories. for each category, a smaller list of the most highly used guides in that category, based on springshare user statistics and to be updated regularly, would be displayed on the homepage, followed by a link to a complete list of guides in the category. at the request of librarians at the university of memphis’s three branch libraries (health sciences, lambuth, and music), guides connected to these branches were also organized together. the bottom of the homepage was dedicated to an ask a librarian help box. figure 4. university of arizona research guides homepage. to create the redesigned subject guides, the rgrt identified a course guide created by the university of memphis’s instruction curriculum coordinator as the design standard. it included tutorials, videos, and other instructional materials guiding students on how to use the linked content.22 each guide would have a standardized set of content pages based on this model, including redirect pages for introduction to research and writing help guides. the rgrt created a list of subject guides and used it to identify redundant guides that could be consolidated into these new subject guides. each guide would be a broad subject area (e.g., business & economics, social sciences), and the main page would cover commonly used resources such as major databases for that area. more specialized resources would be included on topic pages for subareas reflecting specific academic programs (e.g., accountancy, psychology). in the spring of 2021, the rgrt completed the design for the homepage (see fig. 5). it was populated with the new subject guides (see fig. 6 for an example) that followed a standard format (see fig. 7 for the page-level organization). information technology and libraries september 2023

(institutional review board) approval and qualitative data using task scenarios was gathered to gain insights on the new research guides homepage and its linked pages. task scenarios 1, 2, 3, and 5 were designed to reflect real user needs and required access to a variety of different guides, which would involve either using the guides homepage structure or using the libguides search. task scenario 4 was designed to see if users identified the ask a librarian section at the bottom. with a laptop and a series of task scenarios (see table 1), a usability testing center was set up at the university of memphis’s starbucks. for recruitment, two of the authors asked various students in line and socializing at tables to participate. a $5 starbucks gift card was awarded to participants. data from five recruited participants was gathered. before beginning the testing session, one of the authors acted as facilitator, explaining the testing was to ensure the website was intuitive and set up in a way that is helpful. she assured the participants that their knowledge was not being tested. instead, the goal was to make sure that the web page was user-friendly and accessible. the participants were encouraged to use a think-aloud method when completing tasks, so the author acting as note-taker could transcribe the thought process of each participant.23 information technology and libraries september 2023 redesigning research guides 10 mcclure, hess, and marsicano table 1. task scenarios task #1 you need to find information on mla citation. how would you use this page to find that information? task #2 you are in a course titled soci 4420: racial inequality. how would you use this page to find information on that course? task #3 how would you use this page to find historical newspapers to use in a research project? task #4 if you were struggling to access a library resource, how would you use this page to solve the problem? task #5 if you wanted a video explaining how to find articles to use in your research assignment, how would you find it? the same series of task scenarios was given to each participant to complete. the authors began each testing session on a laptop with the research guides homepage already open. the main goal of each testing session was to observe if each participant could successfully complete task scenarios using the homepage and its links to external and internal web pages. the secondary goal was for participants to complete the task scenario with minimal attempts and limited clicks. when a task was completed, the facilitator observed how many attempts were made and if the participant was successful or unsuccessful. a successful attempt was documented if the participant completed the task using the information on the homepage and its links. a successful attempt was also documented if the user did not complete a task but was able to use the page to demonstrate adequate information-seeking behavior (e.g., using chat or the ask a librarian box to seek answers). if a participant did not complete a task, while also not utilizing the homepage to seek answers, then the task was marked as unsuccessful. results out of the 25 total task scenarios conducted during usability testing, 20 were successfully completed and 5 failed (see table 2). a quick summary of each participant’s experiences with completing the task scenarios is provided below. more detailed tables and notes for each participant are included in appendix a. table 2. task scenarios completed or failed by

information technology and libraries september 2023 redesigning research guides 11 mcclure, hess, and marsicano participant #1 successfully completed four out of five task scenarios. they used the topic-based navigation to complete tasks 1, 2, and 5, while they initially failed task scenario 3 using the topic based navigation before completing it using the search bar. they failed task scenario 4, failing to understand the “access a resource” language in the task scenario and stating that they would email someone for help. participant #2 completed all five of the task scenarios. they used topic-based navigation to complete tasks 1 and 2. for task scenario 3, the participant used the search bar. though there was again some confusion over the “access a resource” language used in task 4, the participant stated they would use chat or contact using the information in the ask a librarian box to complete the task. to complete task 5, the participant scanned the homepage and found the library help videos link. participant #3 successfully completed all five task scenarios but required multiple attempts to complete tasks 3 and 4. ultimately tasks 1, 2, 3, and 5 were completed using topic-based navigation. when unsuccessfully clicking various links in an attempt to complete task 4, the participant stated they would contact using the information in the ask a librarian box. participant #4 successfully completed four out of five task scenarios. tasks 1, 2, and 5 were completed using the topic-based navigation, while task scenario 4 was completed by scrolling to the ask a librarian section of the homepage. the participant tried to use the topic-based navigation for task 3, but they found a guide on contemporary, not historical, newspapers and failed the task. participant #5 completed two out of the five task scenarios. task 3 was completed using the search bar and finding an faq on historical newspapers, and task 5 was completed using the topic-based navigation. for task scenario 1, the participant left the research guides homepage using the logo in the banner at the top of the page, which took them to the university libraries website. they had to be returned to the guides homepage for the following tasks. the participant tried to use the topic-based navigation three times to complete task 2 before giving up, and they also tried topic-based navigation for task scenario 4 before giving up. discussion out of the 20 successfully completed task scenarios during the usability testing, 15 task scenarios were completed by users browsing the research guides homepage and making use of the headings and layout. these results demonstrate that the topic-based navigation design separating each section by research help, subject guides, topic guides, and course guides proved effective. users were regularly able to intuit the correct area to look under with minimal errors. scrolling was limited and clicks were few. the search bar was used less frequently, to the surprise of the rgrt. only three task scenarios were successfully completed by using the search. participants often clicked on random pages instead of using the search bar, and even when the search bar was used, it was not always immediately identified by the users. the authors noted that users would skip directly to the four category headings. the success of the ask a librarian section was mixed. three of the five users successfully completed task scenario 4. part of this was that some users were not familiar with the phrase “report access issues,” though once one of the authors explained further, many of them were still information technology and libraries september 2023 redesigning research guides 12 mcclure, hess, and marsicano unsure of who to ask or where to report issues. additionally, only two out of the five participants asked for help when they could not solve other task scenarios. the remaining three gave up or moved onto the next question regardless of the availability of chat or the ask a librarian box. limitations four out of five participants were undergraduate students. an ideal study would have had participants that included an additional graduate student and perhaps a faculty/staff member from the university of memphis. an additional limitation was that the disability status of the participants was unknown, so the accessibility of the design was not formally tested beyond running the design through a web accessibility checker. lastly, the original design was not tested for user errors and assumptions were made based on the rgrt’s observations and usage statistics in springshare. edits were made after usability testing occurred; therefore, improvements in usability between the original homepage design and the revision cannot be shown directly. post-test revisions since most of the task scenarios were completed with successful results, the new design for the research guides homepage proved usable overall. still, when the authors presented the findings to the rest of the rgrt at one of their regular meetings, the group discussed ideas for addressing issues identified in the testing. as a result, some minor changes were made: • the four categories (research help, topic guides, course guides, and subject guides) were moved to the top of the page with the search bar below it. • a graphic was created to draw attention to the search bar. • the music, health sciences, and lambuth campus guides were made more visible by giving each link a university of memphis brand-approved blue background with white lettering. the final product after usability testing was completed is shown in figure 8. the minor changes were not subject to usability testing at the time to test whether they improved the usability of the homepage. further usability testing on the homepage is in the planning stages as the authors write this article. information technology and libraries september 2023 redesigning research guides 13 mcclure, hess, and marsicano figure 8. post-testing redesigned research guides homepage. conclusion these results report one of the three usability testing results conducted on the research guides homepage. the rgrt elected to do three small tests with five users each. these tests were conducted in the same manner as the first, with the authors asking users to complete tasks in a starbucks on a laptop. the only difference was the task scenarios. the rgrt designed new task scenarios for each test to reflect changes made to the homepage based on previous user experiences. for example, there were questions designed to test the relocation of the search bar and the branch library (music, lambuth, and health sciences) headings. a list of task scenarios from the other two tests are included in appendix b and appendix c. this study proves it is imperative that library web page designers familiarize themselves with the users’ information-seeking behavior in their community to design pages to be intuitive and easy to use. while perhaps the most valuable data gleaned from this study was ensuring an effective library web page design, the rgrt also learned that streamlining a workflow and making information technology and libraries september 2023 redesigning research guides 14 mcclure, hess, and marsicano maintenance of research guides a priority is essential for the success of enhancing an academic library’s online presence. furthermore, it is a goal of the rgrt to conduct usability testing of its websites on a quarterly basis, not just on the homepage, but many of its subpages and the design of the guides themselves. the value of usability testing to the university library is exemplified in this study. now, anytime a crucial change is made to research guides, the rgrt is equipped to conduct usability testing to verify modifications and introduce new designs. information technology and libraries september 2023 redesigning research guides

author id box for 2 column layout the present study investigated whether there is a correlation between user performance and compliance with screen-design guidelines found in the literature. rather than test individual guidelines and their interactions, the authors took a more holistic approach and tested a compilation of guidelines. nine bibliographic display formats were scored using a checklist of eighty-six guidelines. twenty-seven participants completed ninety search tasks using the displays in a simulated web environment. none of the correlations indicated that user performance was statistically significantly faster with greater conformity to guidelines. in some cases, user performance was actually significantly slower with greater conformity to guidelines. in a supplementary study, a different set of forty-three guidelines and the user performance data from the main study were used. again, none of the correlations indicated that user performance was statistically significantly faster with greater conformity to guidelines. a ttempts to establish generalizations are ubiquitous in science and in many areas of human endeavor. it is well known that

guidelines are pervasive and difficult challenges, particularly because of the intractably large number of potential interactions among guidelines. using bibliographic display formats from web catalogs, the present study utilizes global evaluation by correlating user performance in a search task with conformity to a compilation of eighty-six guidelines (divided into four subsets). the literature offers many design guidelines for the user interface, some of which cover all aspects of the user interface, some of which focus on one aspect of the user interface—e.g., screen design. tullis, in chapters in two editions of the handbook of human-computer interaction, reviews the work in this area.2 the earlier chapter provides a table describing the screen-design guidelines available at that time. he includes, for example, galitz, whom he notes have several hundred guidelines addressing general screen design, and smith and mosier, whom he notes have about three hundred guidelines addressing the display of data.3 earlier guidelines tended to be generic. more recently, guidelines have been developed for specific applications—e.g., web sites for airline travel agencies, multimedia applications, e-commerce, children, bibliographic displays, and public-information kiosks.4 although some of the guidelines in the literature are based on empirical evidence, many are based on expert opinion and have not been tested. some of the researchbased guidelines have been tested in isolation or in combination with only a few other guidelines. the national cancer institute (nci) web site, research-based web design and usability guidelines, rates sixty guidelines on a scale of 0 to 5 based on the strength of the evidence.5 the more valid the studies that directly support the guideline, the higher the rating. in interpreting the scores, the site advises that scores of 1, 2, or 3 suggest that “more evidence is needed to strengthen the designer’s overall confidence in the validity of a guideline.” of the sixty guidelines on the site, forty-six (76.7 percent) fall into this group. in 2003, the united states department of health and human services web site, research-based web design and usability guidelines, rated 187 guidelines on a different five-point scale.6 eightytwo guidelines (43.9 percent) meet the criteria of having strong or medium research support. another forty-eight guidelines (25.7 percent) are rated as having weak research support. thus, there is some research support for 69.6 percent of the guidelines. in addition to the issue of the validity of individual guidelines, there may be interactions among guidelines. an interaction occurs if the effect of a variable depends on the level of another variable—e.g., an interaction occurs if the usefulness of a guideline depends on whether some other guideline is being followed. a more severe problem is the potential for high-order interactions: the nature of a two-way interaction may depend on the level of a third variable, the nature of a three-way interaction may depend on the level of a fourth variable, and so on. because of the combinatorial explosion, if there are more than a few variables the number of possible interactions becomes huge. as cronbach stated: “once we attend to interactions, we enter a hall of mirrors that extends to infinity.”7 with a large set of guidelines, it is impractical to test all of the guidelines and all of the interactions, including highorder interactions. muter suggested several approaches for handling the problem of intractable high-order interactions, including adapting optimizing algorithms such as simplex, seeking “robustness in variation,” re-construing the problem, and pruning the alternative space.8 the present study utilizes another approach: global evaluation by joan m. cherry, paul muter, and steve j. szigeti bibliographic displays in web catalogs: does conformity to design guidelines correlate with user performance? joan m. cherry (joan.cherry@utoronto.ca) is a professor in the faculty of information studies; paul muter (muter@psych .utoronto.ca) is an assistant professor in the department of psychology; and steve j. szigeti (szigeti@fis.utoronto.ca) is a doctoral student in the faculty of information studies and the knowledge media design institute, all at the university of toronto, canada. bibliographic displays in web catalogs | cherry, muter, and szigeti 155 correlating user performance with conformity to a set of guidelines. using this method, particular guidelines and interactions are not tested, but the set and subsets are tested globally, and some of the interactions, including high-order interactions, are captured. bibliographic displays were scored using a compilation of guidelines, divided into four subsets, and the performance of users doing a set of search tasks using the displays was measured. an attempt was made to determine whether users find information more quickly on displays that receive high scores on checklists of screen-design guidelines. the authors are aware of only two studies that have investigated conformity with a set of guidelines and user performance, and they both included only ten guidelines. d’angelo and twining measured the correlation between compliance with a set of ten standards (d’angelo standards) and user comprehension.9 the d’angelo standards are in the form of principles for web-page design, based on a review of the literature.10 d’angelo and twining found a small correlation (.266) between number of standards met and user comprehension.11 they do not report on statistical significance, but from the data provided in the paper it appears that the correlation is not significant. gerhardt-powals compared an interface designed according to ten cognitive engineering principles to two control interfaces and found that the cognitively engineered interface resulted in statistically significantly superior user performance.12 the guidelines used in the present study were based on a list compiled by chan to evaluate displays of bibliographic records in online library catalogs.13 the set of guidelines was broken down into four subsets. participants in this study were given search tasks and clicked on the requested item on a bibliographic display. the main dependent variable of interest was response time. ฀ method participants twenty-seven participants were recruited through the university of toronto psychology 100 subject pool. seventeen were female; ten were male. most (twenty) were in the age group 17 to 24; three were in the age group 25 to 34 years, and four were in the age group 35 to 44. one had never used the web; all others reported using the web one or more hours per week. participants received course credit. design to control for the effects of fatigue, practice runs, and the like, the order of trials was determined by two orthogonal 9 x 9 latin squares—one to select a display and one to select a book record. each participant completed five consecutive search tasks—author, title, call number, publisher, and date—in a random order, with each display-book combination. (the order of the five search tasks was randomized each time.) this procedure was repeated, so that in total each participant did ninety tasks (9 displays x 5 tasks x 2 repetitions). materials and apparatus the study used nine displays from library catalogs available on the web. they were selected to represent a variety of systems and to illustrate the remarkable diversity in bibliographic displays in web catalogs. the displays differed in the amount of information included, the structure of the display, employment of highlighting techniques, and use of graphical elements. four examples of the nine displays are presented in figures 1a, 1b, 1c, and 1d. the displays were captured and presented in an interactive environment using active server page (asp) software. the look of the displays was retained, but hypertext links were deactivated. nine different book records were used to provide the content for the displays. items selected were those that would be readily understood by most users—e.g., books by saul bellow, norman mailer, and john updike. the guidelines were based on a list compiled by chan from a review of the literature in human-computer interaction and library science.14 the list does not include guidelines about the process of design. chan formatted the guidelines as a checklist for bibliographic displays in online catalogs. in work reported in 1996, cherry and cox modified the checklist for use with bibliographic displays in web catalogs.15 in a 1998 paper, cherry reported on evaluations of bibliographic displays in catalogs of academic libraries, based on chan’s data for twelve opacs and data for ten web catalogs evaluated by cherry and cox using a modification of the 1996 checklist for web catalogs.16 the findings showed that, on average, displays in opacs scored 58 percent and displays in web catalogs scored 60 percent. the 1996 checklist of guidelines was modified by herrero-solana and de moya-anegón, who used it to explore the use of multivariate analysis in evaluating twenty-five latin american catalogs.17 for the present study four questions were removed that were considered less useful from the checklist used in cherry’s 1998 analysis. the checklist consisted of four sections or subsets: labels (these identify parts of the bibliographic description); text (the display of the bibliographic, holdings/ location, and circulation status information); instructions (includes instructions to users, informational messages, and options available); and layout (includes identification of the screen, the organization for the bibliographic 156 information technology and libraries | september 2006 information, spacing, and consistency of information presentation). items on the checklist were phrased as questions requiring yes/no responses. examples of the items are: labels: “are all fields/variables labeled?” text: “is the text in mixed case (upper and lowercase)?” instructions: “are instructional sentences or phrases simple, concise, clear, and free of typographical errors?” and layout: “is the width of the display no more than forty to sixty characters?” the set used in the present study contained eightysix guidelines in total, of which forty-eight were generic and could be applied to any application. thirty-eight are specific and apply to bibliographic displays in web catalogs. the experiment was run on a pentium computer with a seventeen-inch sony color monitor with a standard keyboard and mouse. figure 1a. example of display figure 1b. example of display figure 1c. example of display figure 1d. example of display bibliographic displays in web catalogs | cherry, muter, and szigeti 157 procedure participants were tested individually. five practice trials with a display and book record not used in the experiment familiarized the participant with the tasks and software. at the beginning of a trial, the message “when ready, click” appeared on the screen. when the participant clicked on the mouse, a bibliographic display appeared along with a message at the top of the screen indicating whether the participant should click on the author, title, call number, publisher, or date of publication—e.g., “current task: author.” participants clicked on what they thought was the correct answer. if they clicked on any other area, the display was shown again. an incorrect click was not defined as an error—in effect, percent correct was always 100—but an incorrect click would of course add to the response time. the software recorded the time to successfully complete each search, the identification for the display and the book record, and the search-task type. when a participant completed the five search tasks for a display, a message was shown indicating the average response time on that set of tasks. when participants completed the ninety search tasks, they were asked to rank the nine displays according to their preference. for this task, a set of laminated color printouts of the displays was provided. participants ranked the displays, assigning a rank of 1 to the display that they preferred most, and 9 to the one they preferred least. they were also asked to complete a short background questionnaire. the entire session took less than forty-five minutes. scoring the displays on screen design guidelines the authors’ experience has indicated that judging whether a guideline is met can be problematic: evaluators sometimes differ in their judgments. in this study, three evaluators assessed each of the nine displays independently. if there was any disagreement amongst the evaluators’ responses for a given question for a given display, that question was not used in the computation of the percentage score for that display. (a guideline regarding screen density was evaluated by only one evaluator because it was very time-consuming.) the total number of questions used to assess each display was eighty-six. the number of questions on which the evaluators disagreed ranged from twelve to thirty across the nine displays. all questions on which the three evaluators agreed for a given display were used in the calculation of the percentage score for that display. hence the percentage scores for the displays are based on a variable set and number of questions—from fifty-six to seventy-four. the subset of questions on which the three evaluators agreed for all nine displays was small—twenty-two questions. ฀ results with regard to conformity to the guidelines, in addition to the overall scores for each display, which ranged from 42 percent to 65 percent, the percentage score was calculated for each subset of the checklist (labels, text, instructions, and layout). the time to successfully complete each search task was recorded to the nearest millisecond. (for some unknown reason, six of the 2,430 response times recorded [27 x 90] were 0 milliseconds. the program was written in such a way that the response-time buffer was cleared at the time of stimulus presentation, in case the participant clicked just before this time. these trials were treated as missing values in the calculation of the means.) six mean response times were calculated: author, title, call number, publisher, date, and the sum of the five response times, called all tasks. the mean of all tasks response times ranged from 13,671 milliseconds to 21,599 milliseconds for the nine formats. the nine display formats differed significantly on this variable according to an analysis of variance, f(8, 477) = 17.1, p < .001. the correlations between response times and guidelines-conformance scores are presented in table 1. it is important to note that a high correlation between response time and conformity to guidelines indicates a low correlation between user performance (speed) and conformity to guidelines. row 1 of table 1 contains correlations between the total guidelines score and response times; column 1 contains correlations between all tasks (the sum of the five response times) and guidelines scores. of course, the correlations in table 1 are not all independent of each other. only five of the thirty correlations in table 1 are significant at the .05 level, and they all indicate slower response times with higher conformity to guidelines. of the six correlations in table 1 indicating faster response times with higher conformity to guidelines, none approaches statistical significance. the upper left-hand cell of table 1 indicates that the overall correlation between total scores on the guidelines and the mean response time across all search tasks (all tasks) was 0.469 (df = 7, p = 0.203)—i.e., conformity to the overall checklist was correlated with slower overall response times, though this correlation did not approach statistical significance. figure 2 shows a scatter plot of the main independent variable, overall score on the checklist of guidelines, and the main dependent variable, the sum of the response times for the five tasks (all tasks). figure 3 shows a scatter plot for the highest obtained correlation: between score on the overall checklist of guidelines and the time to complete the title search task. visual inspection suggests patterns consistent with table 1: no correlation in figure 2, and slower search times with higher guidelines scores in figure 3. finally, correlations were computed between preference and response times (all tasks response times and five 158 information technology and libraries | september 2006 specific-task response times) and between preference and conformity to guidelines (overall guidelines four subsets of guidelines). none of the eleven correlations approached statistical significance. ฀ supplementary study to further validate the results of the main study, it was decided to score the interfaces against a different set of guidelines based on the 2003 u.s. department of health and human services research-based web design and usability guidelines. this set consists of 187 guidelines and includes a rating for each guideline based on strength of research evidence for that guideline. the present study started with eighty-two guidelines that were rated as having either moderate or strong research support, as the definitions of both of these include “cumulative research-based evidence.”18 compliance with guidelines that address the process of design can only be judged during the design process, or via access to the interface designers. since this review process did not allow for that, a total of nine process-focused guidelines were discarded. this set of seventy-three guidelines was then compared with the sixty-guideline 2001 nci set, research-based web design and usability guidelines, intending to add any outstanding nci guidelines supported by strong research evidence to the existing list of seventy-three. however, all of the strongly supported nci guidelines were already represented in the original seventy-three. finally, the guidelines in the iso 9241, ergonomic requirements for office work with visual display terminals (vdts), part 11 (guidance on usability), part 12 (presentation of information ), and part 14 (menu dialogues ) were compared to the existing set of seventy-three, with the intention that any prescriptive guideline in the iso set that was not already included in the original seventy-three would be added.19 again, there were none. the seventy-three guidelines were organized into three thematic groups: (1) layout (the organization of textual and graphic material on the screen), (2) interaction (which included navigation or any element with which the user would interact), and (3) text and readability. all of the guidelines used were written in a manner allowing readers room for interpretation. the authors explicitly stated that they were not writing rules, but rather, guidelines, and recognized that their application must allow for a level of flexibility.20 this ambiguity creates problems in terms of assessing displays. in this study, two evaluators independently assessed the nine displays. the first evaluator applied all seventy-three guidelines and found thirty to be nonapplicable to the specific types of interfaces considered. the second evaluator applied the shortened list of forty-three guidelines. following the independent evaluations, the two evaluators compared assessments. the initial rate of agreement between the two assessments ranged from 49 percent to 70 percent across the nine displays. in cases where there was disagreement, the evaluators discussed their rationale for the assessment in order to achieve consensus. ฀ results of supplementary study as with the initial study, in addition to the overall scores for each display, the percentage score was calculated for each subset of the checklist (labels, interaction, and text and readability). it is worth noting that the overall scores witnessed higher compliance to this second set of guidelines, ranging from 68 percent to 89 percent. the correlations between response times and guidelines-conformance scores are presented in table 2. again, it is important to note that a high correlation between response time and conformity to guidelines indicates a low correlation between user performance (speed) and conformity to guidelines. row 1 of table 2 contains correlations between the total guidelines score and response times; column 1 contains correlations between all tasks (the sum of the five response times) and guidelines scores. of course, the correlations in table 2 are not all independent of each other. only one of the twenty-four correlations in table 2 table 1. correlations between scores on the checklist of screen design guidelines and time to complete search

significant at the .05 level, and it indicates a slower response time with higher conformity to guidelines. of the ten correlations in table 2 indicating faster response times with higher conformity to guidelines, none approaches statistical significance. the upper left-hand cell of table 2 indicates that the overall correlation between total scores on the guidelines and the mean response time across all search tasks (all tasks) was 0.292 (p = 0.445)—i.e., conformity to the overall checklist was correlated with slower overall response times, though this correlation did not approach statistical significance. figure 4 shows a scatter plot of the main independent variable, overall score on the checklist of guidelines, and the main dependent variable, the sum of the response times for the five tasks (all tasks). figure 5 shows a scatter plot for the highest-obtained correlation: between score on the text and readability category of guidelines and the time to complete the title search task. visual inspection suggests patterns consistent with table 2: no correlation in figure 4, and slower search times with higher guidelines scores in figure 5. ฀ discussion in the present experiment and the supplementary study, none of the correlations indicating faster user performance with greater conformity to guidelines approached statistical significance. in some cases, user performance was actually significantly slower with greater conformity to guidelines—i.e., in some cases, there was a negative correlation between user performance and conformity to guidelines. the authors are aware of no other study indicating a negative correlation between user performance and conformity to interface design guidelines. some researchers would not be surprised at a finding of zero correlation between user performance and conformity to guidelines, but a negative correlation is somewhat puzzling. a negative correlation implies that there is something wrong somewhere—perhaps incorrect underlying theories or an incorrect body of assumptions. such a negative correlation is not without precedent in applied science. in the field of medicine, before the turn of the twentieth century, seeing a doctor actually decreased the chances of improving health.21 presumably, medical guidelines of the time were negatively correlated with successful practice, and the negative correlation implies not just worthlessness, but medical theories or beliefs that were actually incorrect and harmful. the boundary conditions of the present findings are unknown. the present findings may be specific to the tasks employed—fairly simple search tasks. the findings may apply only to situations in which the user is switching formats frequently, as opposed to situations in which each user is using only one format. (a between-subjects design would test this possibility.) the findings may be specific to the two sets of guidelines used. with sets of ten guidelines, d’angelo and twining and gerhardt-powals found positive correlations between user performance and conformity to guidelines (though apparently not statistically significantly in the former study).22 the guidelines used in the authors’ main study and supplementary study tended to be more detailed than in the other two studies. detailed guidelines are sometimes seen as advantageous, since developers who use guidelines need to be able to interpret the guidelines in order to implement them. however, perhaps following a large number of detailed figure 2. scatter plot for overall score on checklist of screen design guidelines and time to complete set of five search tasks figure 3. scatter plot for overall score on checklist of screen design guidelines and time to complete “title” search tasks 160 information technology and libraries | september 2006 guidelines reduces the amount of personal judgment used and results in less effective designs. (designers of the nine displays used in the present study would not have been using either of the sets of guidelines used in our studies but may have been using some of the sources from which our guidelines were extracted.) as noted by cheepen in discussing guidelines for voice dialogues, sometimes a designer’s experience may be more valuable than a particular guideline.23 the lack of agreement in interpreting the guidelines was an unexpected but interesting factor revealed during the collection of data in both the main study and the supplementary study. while a higher rate of agreement had been expected, the differences raised an important point in the use of guidelines. if guidelines intentionally leave room for interpretation, what factor does expert opinion and experience play in design? in the main study, the number of guidelines on which the evaluators disagreed ranged from 14 percent to 35 percent across the nine displays. in the supplementary study, both evaluators had experience in interface design through a number of different roles in the design process (both academic and professional). this meant the evaluators’ interpretations of the guidelines were informed by previous experience. the initial level of disagreement ranged from 30 percent to 51 percent across the nine displays. while it was possible to quickly reach consensus table 2. correlations between scores on subset of the u.s. dept. of health and human services (2003) research–based web design and usability guidelines and time to complete search tasks: pearson correlation (sig. 2-tailed); n=9 all cells all tasks author title call # publisher year total score: .292 (.445) .201 (.604) .080 (.839) -.004 (.992) .345 (.363) .499 (.172) layout: -.308 (.420) -.264 (.492) -.512 (.159) -.332 (.383) .046 (.906) -.294 (.442) text: .087 (.824) -.051 (.895) .712 (.032) -.059 (.879) -.095 (.808) -.259 (.500) interaction: .638 (.065) .603 (.085) .055 (.887) .439 (.238) .547 (.128) .625 (.072) figure 4. scatter plot for subset of u.s. department of health and human services (2003) research–based web design and usability guidelines conformance score and total time to complete five search tasks figure 5. scatter plot for text and readability category of u.s. department of health and human services (2003) research–based web design and usability guidelines and time to complete “title” search tasks bibliographic displays in web catalogs | cherry, muter, and szigeti 161 on a number of assessments (because both evaluators recognized the high degree of subjectivity that is involved in design), it also led to longer discussions regarding the intentions of the guideline authors. a majority of the differences involved lack of guideline clarity (where one evaluator had indicated a meet-or-fail score, while another felt the guideline was either unclear or not applicable). does this imply that guidelines can best be applied by committees or groups of designers? the dynamic of such groups would add another complex variable to understanding the relationship between guideline conformity and user performance. future research should test other tasks and other sets of guidelines to confirm or refute the findings of the present study. there should also be investigation of other potential predictors of display effectiveness. for example, would the ratings of usability experts or graphic designers for a set of bibliographic displays be positively correlated with user performance? crawford, in response to a paper presenting findings from an evaluation of bibliographic displays using a previous version of the checklist of guidelines used in the main study, commented that the design of bibliographic displays still reflects art, not science.24 several researchers have discussed aesthetics and user interface design. reed et al. noted the need to extend our understanding of the role of aesthetic elements in the context of user-interface guidelines and standards.25 ngo, teo, and byrne discussed fourteen aesthetic measures for graphic displays.26 norman discussed these ideas in “emotions and design: attractive things work better.”27 tractinsky, katz, and ikar found strong correlations between perceived aesthetic appeal and perceived usability.28 most empirical studies of guidelines have looked at one variable only or, at the most, a small number of variables. the opposite extreme would be to do a study that examines a large number of variables factorially. for example, assuming eighty-six yes/no guidelines for bibliographic displays, it would be theoretically possible to do a factorial experiment testing all possible combinations of yes/no—2 to the 86th power. in such an experiment, all two-way interactions and higher interactions could be assessed, but such an experiment is not feasible. what the authors have done is somewhere between these two extremes. this study has the disadvantage that we cannot say anything about any individual guideline, but it has the advantage that it captures some of the interactions, including highorder interactions. despite the present results, the authors are not recommending abandoning the search for guidelines in interface design. at a minimum, the use of guidelines may increase consistency across interfaces, which may be helpful. however, in some research domains, particularly when huge numbers of potential interactions result in extreme complexity, it may be advisable to allocate resources to means other than attempting to establish guidelines, such as expert review, relying on tradition, letting natural selection take its course, utilizing the intuitions of designers, and observing user-interaction. indeed, in pure and applied research in general, perhaps more resources should be allocated to means other than searching for explicit generalizations. future research may better indicate when to attempt to establish generalizations and when to use other methods. ฀ acknowledgements this work was supported by a social sciences and humanities research council general research grant awarded by the faculty of information studies, university of toronto, and by the natural sciences and engineering research council of canada. the authors wish to thank mark dykeman and gerry oxford who developed the software for the experiment; donna chan, joan bartlett, and margaret english, who scored the displays with the first set of guidelines; everton lewis, who conducted the experimental sessions; m. max evans, who helped score the displays with the supplementary set of guidelines; and robert l. duchnicky, jonathan l. freedman, bruce oddson, tarjin rahman, and paul w. smith for helpful comments. references and notes 1. see, for example, a. chapanis, “some generalizations about generalization,” human factors 30, no. 3 (1988): 253–67. 2. t. s. tullis, “screen design,” in handbook of human-computer interaction, ed. m. helander (amsterdam: elsevier, 1988), 377–411; t. s. tullis, “screen design,” in handbook of humancomputer interaction, 2d ed., eds. m. helander, t. k. landauer, and p. prabhu (amsterdam: elsevier, 1997), 503–31. 3. w. o. galitz, handbook of screen format design, 2d ed.

portal that enables user access to all local and networked resources, or it may be a tool of byzantine complexity, comprehensible at best to but a small fraction of librarians able to navigate its bibliographic metadata encoded in an arcane 1960s-era format. it is a rich trove of structured and controlled information assembled over decades by the work of countless dedicated catalogers and others. or, it is the now-obsolete product of a labor-intensive process of description and subject analysis that has no relevance in a web-centric world where “everything” is findable via the google search-box. its attempt to organize knowledge provides catalogers with a raison d’etre, but sends their colleagues and many users fleeing for simpler and more all-encompassing tools. it is our alpha and omega, our yin and our yang. few topics in librarianship—perhaps with the conspicuous exception of that perennial library school favorite, our profession’s status as a profession—seem to provoke the range and depth of sentiment engendered by discussions of the place of the catalog. especially in recent years, criticism of the catalog has grown ever more strident, to the point where it has become commonplace in our profession’s literature to say that this most basic of library services “sucks.” as a consequence, librarians have increasingly fallen into one of two camps, with those critical of the catalog often simplistically characterized as favoring, and those defending it as opposing “change.” a number of initiatives have emerged in response to this ferment. some of these have focused on our bibliographic metadata, and particularly on its ability to express the relationships and interconnectedness of the bibliographic universe. as we have traditionally cataloged whatever we had “in-hand,” our cataloging codes and encoding standards have done a very good job of managing the description of bibliographic items; what they have not generally expressed well are the relationships among items. frbr and frad—the functional requirements for bibliographic records and the functional requirements for authority data—seem promising beginnings for addressing the relationship issues, although there are as-yet very few practical implementations. resource description and access (rda), the forthcoming successor to aacr2, is designed around frbr concepts; it will be interesting to see how this plays out in the “real world;” equally interesting will be to what degree the present (or a modified) marc21 is able to express rda’s frbr-based relationship model. other approaches have focused on developing systems that are able to exploit our existing investment in bibliographic metadata in new and useful ways. the pioneering and best-known example of this, of course, is the discovery tool developed by a partnership of north carolina state university libraries and endeca, which premiered in early 2006. this initiative included several innovative features not previously found in library catalogs, such as search result relevance ranking and the ability to perform faceted searching against a variety of controlledvocabulary indices (subject/topical, form/genre, date, etc.) ncsu’s endeca discovery tool spawned an entirely new product segment for the catalog: major ils vendors have scrambled to develop their own next-gen products, combining relevancy and facets with additional functionality such as web 2.0 social and collaborative tools and enhanced federated searching capabilities. the result of all this activity has been the first cross-platform growth opportunity for ils vendors since the development of resource-linking tools and the erm. we at ital have watched these trends with keen interest and have published works describing many of the major developments vis-a-vis the catalog in recent years. indeed, since late 2004, ital has published at least eleven major papers on various topics related to improving the catalog. with our publication of jennifer bowen’s report on the first phase outcomes of the university of rochester’s extensible catalog (xc) project in this issue of ital, we continue our commitment to publish important research in this area. the rochester project is noteworthy, both for its modular and metadata-focused approach and for its high visibility as an open source effort that has received significant support from the andrew w. mellon foundation. i predict that this paper will quickly take its place among the other ground-breaking works on the catalog that ital has published, and i’ll eagerly be awaiting the next progress report on the xc. n “must-reads” dept. okay, so i may not be the first out of the gate with this one, but for those of you who haven’t looked at it yet, trust me, you’ll want to. jonathan zittrain’s the future of the internet and how to stop it (yale university press, 2008), which divides the internet into “generative” technologies such as the pc, and proprietary appliances such as the iphone, may or may not resonate with you, but i think it could well become the next big debate about where the net is and where it should be going. grab a copy and

schmidt evaluation of electronic mail project. the members of the board reviewed their experiences and impressions with the ontyme electronic mail system. the general consensus was that the system was very good and everyone was pleased with it and wants to expand its use. the board has not yet used the source, although we are now subscribers to the system. motion was made by markuson , seconded by rehnberg, and passed that: the electronic mail project be extended through the midwinter meeting, 1982, with a total budget of $2,000 from the inception of the project. uta's representation on ansi x-3. x-3 is the american national standards institute committee on computers and information processing. discussion included the mechanics of keeping the membership informed of proposed standards being considered, the large amount of time required of the representahighlights of meetings 323 tive to monitor, study, and disseminate the proposed standards, and the costs involved for lit a to support a representative. juergens requested that if a division-wide representative to x-3 is appointed that that person should also be made ex officio to the isas/tesla committee or be liaison to the chair of isas. no action was taken. goals and long-range planning committee. kenney announced that she had appointed an ad hoc goals and long-range planning committee chaired by george abbott. directory of library systems in use. the suggestion was made that a directory of the many automated systems in use in libraries would be very useful. a motion was made by markuson, seconded by kenney, and passed that: in response to inquiry about a directory to assist in identifying specific applications of technology in libraries, media, and information centers, that the publications committee explore the feasibility of an online lit a directory of library, media, and information center use of technology. the investigation should consider format of description, potential of interactive online updating, and possible output byproducts, and should result in a draft rfp for consideration by the lit a board for review at midwinter. president's program at philadelphia. kenney announced her plans for the lit a president's program at the philadelphia ala annual conference. she is planning to transmit by satellite to fifty receiving sites around the country an "ala sampler" of outstanding technically-based programs from the philadelphia conference and short vignettes of what ala is all about. the subject of "0 n-line catalogs" has been chosen for the president's program and segments of it and the rtsd/lit airasd preconference institute on the same subject will be used. the program is intended for people who cannot get to ala conferences. if not enough registration is received by the coming ala midwinter meeting the whole activity would be cancelled. oral history project. at the 1980 new york ala conference, the suggestion was made that in the future many of the pioneers in the field of library automation will pass off the scene and it was felt that it was lit a's responsibility to capture for posterity the ideas and philosophy of those people. a motion was made by kenney, seconded by eaton, and passed that: an ad hoc committee be formed to investigate an oral history project in all aspects and submit a detailed set of alternative approaches for the board's consideration. the library history roundtable will be informed of the committee's activity and invited to participate. second session june 30, 1981 board members present: s. michael malinconico, brigitte l. kenney, barbara e. markuson, nancy l. eaton , kenneth}. bierman, ronald f. miller, bonnie k. juergens, marilyn j. rehnberg, helen cyr , heike kordish , charles husbands, and donald p. hammer. 324 journal of library automation vol. 14/4 december 1981 lita section reports: isas. bonnie juergens, chairperson of isas, reported that the section has approved three programs for the philadelphia conference. asis will be asked to cosponsor the program "information science, computer science, and library science: in search of common ground". another program is the "the uses of microcomputers in medium-sized public and academic libraries," and the third one will be a detailed analysis and comparison of the marc format. juergens reported that the isas retrospective conversion discussion group and one of the same name in rtsd would like to combine. a motion was made by juergens, and passed that: isas pursue appropriate steps to invite the rtsd section which currently hosts a discussion group on retrospective conversion to combine that discussion group with the lit a/isas retrospective conversion discussion group. the invitation to rtsd will include a specific description of mutual responsibilities. electronic library membership initiative group. (information report by richard sweeney, public library of columbus and franklin co., ohio; and neal kaske, oclc.) sweeney reviewed the discussions that took place at a meeting held in columbus on march 23-24, 1981 concerned with the whole area of remote electronic access to information and its impact on the library field. the group concluded that its members want to have some input on a very immediate level on the direction technology goes and the direction the policies and issues go. out of that meeting came a mission statement which is now the function statement of the ala electronic library membership initiative group (elmig). sweeney read that statement and reported on the group's concern for the future of libraries when these remote systems become established. he commented on the large number of programs and meetings on these areas that are not coordinated and not really providing the leadership our field should be giving. the almost total lack of research on these areas was also commented on. the need for the associations to provide the leadership was stressed. several members of the lita board expressed interest in providing a "home" for elmig within lita as many of lit a's interests are those of the mig. both groups are concerned with the same issues it was pointed out. lita section reports: audio-visual section. avs recommended that an audiovisual task force be established, which would include other ala units, and would share information about their plans, and would try to avoid major schedule conflicts and overlaps. a motion was made by cyr, and passed that lit a board approve ad hoc lit a a-v section participation in a broadbased task force involving rtsd, pla, acrl, aasl and others to coordinate audiovisual-related activities. cyr asked board's sanction for a "a-v interest group breakfast" where people could just socialize and talk together. this would be sometime in the future. the board members had no objection. marbi committee report. elaine woods reported that the marbi committee is focusing more on the principles and the issues that need to be highlights of meetings 325 addressed in the marc format. the committee is current with l.c. proposals. marbi has drawn up a shopping list of issues to be addressed and they are now working on some of them. publications committee report. charles husbands informed the board that the publications committee feels it is time to change the title of lola. they have chosen a title of information technology and libraries, and it is to be effective with the march 1982 issue. after discussion, a motion was made by bonnie juergens, and passed to that effect. the matter of raising the subscription price of lola was discussed. due to the fact that the division's subsidy to the journal will greatly increase next budget year, the motion was made by ken bierman, and passed that: non-member prices for the journal of the division be increased to $20 for a one-year subscription and $5.50 for a single issue, effective with march 1982, and that the published member subscription price be raised sufficiently to conform to postal regulation. husbands requested that various members of the lola editorial board be included in the lita electronic mail system. approved by the board by consensus. husbands asked the board to keep in mind the possibility of publishing some of the results of the oral history project in lola. brian aveney asked the board to allow him to investigate the possibility of putting the full text of lola online. it would be an experiment to see what people would do with it. the board approved by consensus. aveney will return with a final proposal later. other such ideas were discussed including the proposals to put the "headlines" from the lita newsletter on the source, and to include the roster of lita committees in the oclc address directory. arrangements are in process for both of these activities. goals and long-range planning committee. george abbott, chairperson, asked the board's permission to include his committee on lit a's electronic mail system. the intent would be to use it for text editing of committee documents. board approved by consensus. abbott reported that the committee expects to hold open hearings at midwinter and to have a basic document for discussion at that time. third session june 30, 1981 board members present: s. michael malinconico, brigitte l. kenney, ronald f. miller, kenneth j. bierman, marilyn j. rehnberg, heike kordish, and donald p. hammer. bylaws and organization report. there have been seven changes to the lit a bylaws that kordish will prepare in text form for the board to act on at midwinter in time for the spring ala ballot. ala priorities survey. ron miller reported that the ala executive board took action on the ala priorities and there are five of them. briefly, they are 326 journal of library automation vol. 14/4 december 1981 access to information , legislation and funding, intellectual freedom, public awareness, and personnel resources. joint council on educational telecommunications. lynne bradley reported that jcet has established a task force to bring information to its members about the new technologies and how they can best be used in education. since lit a members have much of the necessary expertise, bradley suggested that lita organize a one-day program for jcet. some board members were very much interested and bradley was asked to work with the lit a program planning committee to organize such a program. program planning committee. sue tyner reported that the telecommunications committee will hold a preconference institute at the philadelphia annual conference called "the teleconference center." it is intended to teach librarians how to set up a teleconference center. the lit a group that has been putting on the "data processing specifications and contracting" workshops has been asked to hold a workshop prior to the ifla meeting. malinconico suggested that the board adopt a policy of lit a costs plus 15 percent, but that a subcommittee of the lit a program planning committee should be set up to define policy in this area. carolyn gray was suggested as a person for this committee. marilyn rehnberg, chairperson of vccs, reported a request from national audio-visual association asking lit a to put on a " video

of oclc’s questionpoint service for managing electronic publications and other items that fall outside the scope of oclc library’s opac and web resources pages, yet need to be “put somewhere.” the local knowledge base serves as both a collection development tool and as a virtual vertical file, with records that are easy to enter, search, update, or delete. we do not deliberately collect for the vertical file, but add to it day by day the useful thing which turns up. these include clippings from newspapers, excerpts from periodicals . . . broadsides that are not injured by folding . . . anything that we know will be used if available. —wilson bulletin, 1919 i nformation that “will be used if available” sounds like the contents of the internet.1 as with libraries everywhere, the oclc library has come to depend on the internet as an almost limitless resource. and like libraries everywhere, it has confronted the advantages and disadvantages of that scope. this means that in addition to using the opac and oclc library’s webpages, oclc library staff have used a mix of bookmarks, del.icio.us tags, and post-it® notes to keep track of relevant, authoritative, substantive, and potentially reusable information. much has been written about the use of questionpoint’s transaction management capabilities and of the important role of knowledge bases in providing closure to an inquiry. in contrast, this article will look at questionpoint’s use as a management tool for future questions, for items that fall outside the scope of oclc library’s opac and web resources pages yet need to be “put somewhere.” the questionpoint local knowledge base is just the spot for these new vertical file items. about oclc library oclc is the world’s largest nonprofit membership computer library service and research organization. more than 69,000 libraries in 112 countries and territories around the world use oclc services to locate, acquire, catalog, lend, and preserve library materials. oclc library was established in 1977 to provide support for oclc’s mission. the collection concentrates on library, information and computer sciences, business management, and has special collections that include the papers of frederick g. kilgour and archives of the dewey decimal classification™. oclc library has a distinct clientele to which it offers a complete range of services—print and electronic collections, reference, interlibrary loan—within its subject areas. because of the nature of the organization, the library supports longterm and collaborative research, such as that done by oclc programs and research staff, as well as the immediate information needs of product management and marketing staff. oclc library also provides information to oclc’s other service areas, such as finance and human resources. while most oclc library acquisitions are done on demand, oclc library selects and maintains an extensive collection of periodicals, journals, and reference resources, most of them online and accessible—along with the opac—to oclc employees worldwide from the library’s webpages (see figure 1). often, however, oclc staff, like those of many organizations, are too busy to consult these resources themselves and thus depend on the library. oclc library staff pursue the answers to such research questions through its collections and look to enhance the collections with “anything that we know will be” of use. one of the challenges is keeping track of the “anything” that falls outside the library’s primary collections scope; questionpoint helps with that task. traditional uses of questionpoint questionpoint is a service that provides question management tools aimed at increasing the visibility of reference services and making them more efficient. oclc library uses many of those tools, but there are significant ones it does not use (for example, chat). and although the library’s questionpoint-based aska link is visible by default on the front page of the corporate intranet as well as on oclc library–specific pages, less than than 8 percent of questions over the last year were received through that link. one reason for this low use may be that for most of oclc library’s history, e-mail has been the primary contact method, and so it remains. even when the staff need clarification of a question, they automatically opt for telephone or e-mail messaging. working with a web form and question-and-answer software has not caught on as a replacement for these more established methods. however, questionpoint remains tam

accessible only by oclc library staff.) not surprisingly, most of the questions received are about libraries, museums, and other cultural institutions, their collections, users, and staff. this means that the likelihood of reuse of the information in the oclc library knowledge base is relatively high, and makes the local knowledge base an early stop in the reference process. though statistics vary widely by individual institutions and type of library—and though some libraries have opted not to use the knowledge base—the average ratio for all questionpoint libraries is about one knowledge base search for every three questions received. in contrast, in the past year oclc library staff averaged 4.2 local knowledge base searches for every three questions received. the view of the questionpoint knowledge base as a repository of answers to questions that have been asked is a traditional one. oclc library’s use of the questionpoint knowledge base in anticipation of information needs of its clients—as a way of collection development—is distinctive. in many respects this use creates an updated version of the oldfashioned vertical file. nontraditional uses of questionpoint just-in-case the vertical file has a quirky place in the annals of librarianship. it has been the repository for facts and information too good to throw away but not quite good enough to catalog. h. w. wilson still offers its vertical file index, a specialized subject index to pamphlets issued on topics often unavailable in book form, which began in 1932. by now, except for special collections, the internet has practically relegated the vertical file to the backroom with the card platens and electric erasers. oclc library now uses its questionpoint knowledge base to manage information that once might have gone into a vertical file: the authoritative reports, studies, .org sites, and other resources that are often not substantive enough to catalog, but too good to hide away in a single staff member’s bookmarks. the questionpoint knowledge base provides a place for these resources; more importantly, questionpoint provides fast, efficient ways to collect, tag, manage, and use them. questionpoint allows development of such collections with powerful capabilities that allow for future retrieval and use of the information, and it does so without the incredibly time-consuming processes of the past. a 1909 description of such processes describes in detail the inefficiency of yore: in the public library [sic] of newark, n.j., material is filed in folders made of no. 1 tag manila paper, cut into pieces about 11x18 inches in size. one end is so turned up against the others as to make a receptacle 11x19 1/2 inches. the front fold is a half inch shorter than the back one, and this leaves a margin exposed on the back one, whereon the subject of that folder is written.2 thus a major benefit of using questionpoint to manage these resources is saving time. because questionpoint is a routine part of oclc library’s workflow, it allows the addition of items directly to the figure 1. oclc library intranet homepage introducing zoomify image | smith 27“just in case” answers: the twenty-first-century vertical file | dalrymple 27 knowledge base quickly and with a minimum of fuss. there is initially no need to make the entry “pretty,” but only to describe the resource briefly, add the url, and tag it (see figure 2). unlike a physical vertical file, tagging items in the knowledge base allows items to be “put” in multiple places. staff can also add comments that characterize the authoritativeness of a resource. occasionally librarians come across articles or resources that might address multiple questions. instead of burying the data in one overarching knowledge base record, staff can make an entry for each aspect of the resource. an example of this is www .galbithink.org/libraries/analysis. htm, a page created by douglas galbi, senior economist with the federal communications commission (see figure 3). the site provides statistics, including historical statistics, on u.s. public libraries. rather than describe these generically with a tag like “library statistics”—not very useful in any case—each source can be added separately to the questionpoint knowledge base. for example, the item “audiovisual materials in u.s. public libraries” can be assigned specific tags—audiovisual, av, videos—that will make the data more accessible in the future. in other words, librarians use the faq model of asking and answering just one question at a time. an important element in adding “answers” to oclc library’s knowledge base is the ability to provide context. with questionpoint, librarians can not only describe what the resource is, but why it may be of future use. and just the act of adding information to the knowledge base serves as a valuable mnemonic— “i’ve seen that somewhere.” records added to the knowledge base in this way can be easily updated with information about newer editions or better sources. equally valuable is the ability to edit and add keywords when the resource becomes useful for unforeseen questions. sharing information with staff the knowledge base also serves as a more formal collection development tool. when librarians run across potentially valuable resources, they can send a description and a link to a product manager who may find it of use. library staff use questionpoint’s keyword capability to add tags of people’s names and job titles to facilitate ongoing current awareness. employees may provide feedback suggesting an item be added to the figure 3. a page with diverse facts and figures: www.galbithink.org/libraries/analysis.htm figure 2. a sample questionpoint entry, this for a report by the

website. oclc library strives to inform users without subjecting them to information overload. when a 2007 survey of oclc staff found the library’s rss feeds seldom used, librarians began to send e-mails directly to individuals and teams. the reaction of oclc staff indicates that such personal messages, with content summaries that allow recipients to quickly evaluate the contents, are more often read than oclc library rss feeds—especially if items sent continue to be valuable. requirements that enable this kind of sharing include knowledge of company goals, staff needs, and product initiatives. to keep up-todate, librarians meet regularly with other oclc staff, and monitor organizational changes. attendance at oclc’s members council meetings provides information on hot topics that help identify resources for future use. while oclc’s growth as a global organization has brought challenges in maintaining awareness of the full range of organization needs, the questionpoint knowledge base offers a practical way to manage increased volume. maintaining resources of potential interest to staff with questionpoint has another benefit: it helps keep librarians aware of internal experts who can help the library with questions, and in many cases allows the library to connect staff with mutual interests to one another. this has become especially important as oclc has grown and its services continue to integrate with one another. conclusions beyond its usefulness as a system to receive, manage, and answer inquiries, questionpoint is providing a way to facilitate access to online resources that addresses the particular needs of oclc library’s constituency. it is fast and easy to use: a standard part of the daily workflow. it enables direct links to sources and accommodates tagging those sources with the names of people and projects, as well as subjects. it serves as part of the library’s collection management and selection system. using questionpoint in this way has some potential drawbacks. “just in case” acquisition of virtual resources entails some of the risks of traditional acquisitions: acquiring resources that are seldom used, creating a database of resources that are difficult to retrieve, and perhaps the necessity of “weeding” or updating obsolete items. with company growth comes the issue of scalability, as well. but for now, the benefits have far outweighed the risks. most of the items added have been identified for and shared with at least one staff member, so the effort has provided immediate payoff. n the knowledge base serves as a collection development tool, helping to identify items that can be cataloged and added to the permanent collection. n the record in the knowledge base can serve as a reminder to check for later editions. n the knowledge base records are easy to update or even delete. the questionpoint virtual vertical file helps oclc library manage and share those useful things that “just turn up.”

from the editor: the core question letter from the editor the core question kenneth j. varnum information technology and libraries | march 2020 https://doi.org/10.6017/ital.v39i1.12137 as i write this, the members of the association for library collections and technical services (alcts), the library leadership and management association (llama), and lita are voting to merge into a new consolidated division, core: leadership, infrastructure, futures. this merger is essential to the continuing activities that we library technologists rely on. the lita board has indicated that if the merger does not go through, lita will be forced to dissolve over the coming year. the merger will enrich lita members’ opportunities. lita has long focused on the library technology practitioner. that has been our core competency, born of a time when technology was the new thing in libraries. we technologists know—the entire information profession knows— that technology is no longer an addition to a library, but is the way society operates, for a huge portion of our work and life. core reflects this evolutionary change. similar evolutions have taken place in technical services and collections development areas; those functions have been forever changed by the wave of technologies that we have implemented over the past half century. core brings together the practitioners and technologies that make libraries run, and combines them with the library leadership areas that many of us aspire to, or end up taking on, as our careers develop. when i joined lita over a decade ago, i was myself moving from “doer” to “manager.” now that my role is largely project and personnel management, the skills and conversations i seek for personal growth are often found in other parts of ala, and beyond. yet, the focus—the core, if i may—of what i do is still in the center of the venn diagram of technology, people, and data. i voted to support core and hope that all of you who belong to lita, alcts, and/or llama, will do the same. sincerely, kenneth j. varnum, editor varnum@umich.edu march 2020 https://core.ala.org/ mailto:varnum@umich.edu lib-s-mocs-kmc364-20141005023522 61 from the editor at the january 1973 midwinter meeting of the american library association, the board of directors of the information science and automation division appointed me to the position of editor of the journal of library automation. i wish to express gratitude to don s. culbertson, at that time executive secretary of both the information science and automation division and the american library trustees association, for adding yet another hat while he prepared a substantial portion of this june 1972 issue of jola. as incoming editor, i also wish to describe briefly to the subscribers and regular readers of jola the situation of the journal and my plans for its immediate future. you are aware that there has been a hiatus in the publication of jola. at this writing, the journal is approximately ten months behind schedule. by taxing the capacity of the ala staff, jola should return to its normal schedule within a year. during the intervening period, i will appreciate greatly the support of isad members, jola readers, authors, and the ala staff. with this support the task will be made lighter and perhaps will be expedited. no substantial changes in editorial policy will be made in the near future, as all efforts will be turned toward bringing the journal up to scheduje. susan k. martin, editor 17 march 1973 75 video technologies: neologism or library trend? converging factors are shaping a new environment for libraries, and, as a consequence, the present is full of opportunity. technical and social changes provide libraries with a host of alternatives for service, growth, and innovation. in this new environment libraries will, undoubtedly, continue to promote the availability of books and other materials, continue to increase their efforts to furnish patrons with information, and continue to broaden the range of activities offered so that patrons can receive personalized service. patron information seeking and searching methods we have known, however, will give way to new methods based on computers and telecommunications. a host of new technologies is growing out of the evolutionary pathway marked by telegraph, telephone, radio, and television . broadband communications (that's the cable that today brings you predominantly entertainment television), satellite, videotex, teletext, videodisc, videotape, large-screen television, and computer displays (some are as large as the side of a building) are available either today or within the next year or two . each of these technologies is a new medium within its own inherent capabilities and limitations. each has the promise of providing faster and more cost-efficient information services than some present forms of printed communication. and each requires a different approach and different knowledge for effective and efficient use, and integration into library operations. in a growing number of locations, cable communications for delivery of library se rvices have already been made available virtually free of charge . other technologies, such as videotex, will grow significantly . estimates suggest that in five years more than 8 million american homes will be able to obtain extensive, automated information services from commercial, private, and government sources . probably a larger number will receive limited information services over the broadcast airwaves via teletext. dramatic new services will combine television, computer, telephone, satellite, and cable into home entertainment and information centers ... potential extensions of libraries. some sources suggest more than 50 percent of the american gross national product results from the collection, processing, and dissemination of information, much of which involves new technologies . inev76 journal of library automation vol. 14/2 june 1981 itably, this technological trend also will occur in libraries and, in this light, the relatively low level of involvement of computers in providing patron services today is notable. by their natural inertia, individuals and organizations in the library community will be opposed to the acceptance of cable services, videotex , online catalogs, information retrieval , and other video technologies simply because it represents change . but these technologies are technically feasible and are becoming an economic reality. the point of demarcation between computer and library may well become a terminal in a patron's home. whether or not the service provided is a library's or a commercial competitor's depends to a great extent on how libraries define their role in this environment, and on the degree of library participation in the evolutionary process that's now taking place. something besides inertia opposes the acceptance of new technologies, however. to some degree, lack of awareness of technological trends is a factor, but more significant is a lack of clear understanding (both by the proponents of the technology and by librarians) of how new technology can be integrated into the library setting. understanding the value a technology offers for increased service or decreased cost, for example should be paramount, but frequently the technology seems to be offered as an end in itself. internal and external factors must be considered to guide the application of technology toward meeting library and patron needs. financial concerns, social forces , and the consumer/patron appear to be major factors leading libraries toward a future deeply involved in video technologies. whether the outcome will result from external pressure or internal plan remains to be seen. it's incumbent upon libraries to be informed and active participants in directing their own future in this kind of an environment. what are the implications of this technical evolution and internal/external factors? one thing is sure: it's a massive industry growing at a very rapid rate, and it is going to grow even faster . libraries have the opportunity to grow with this trend through application of the technologies to existing technical services, increased availability of patron services, and development of innovative services . if there is a common thread that can identify those libraries which will grow and prosper, that thread is flexibility the capacity of library management and staff to adapt this library to the new environment, and integrate technology into their library. readers and contributors of ]ola are the people that can e ither have an integral part in defining the future direction of libraries, or passively watch patron needs outstrip services. library schools and people involved in library-related research must play a key role in assessing the value of video technologies and defining how to integrate them into the business and service of libraries. what is going to preserve and enhance editorial!harnish 77 the role of libraries in the 1980s will not only be flexibility but another very critical element foresight, dedicated to patron needs . many libraries have met this technological revolution head-on and are intimately involved in testing, developing, and providing innovative library services . in this and forthcoming issues, we hope to bring a perspective on these changes that is valuable and cogent to the library community. readers of ]ola and practitioners in all areas of video technology are called upon to describe their efforts and share their results drawn from this rapidly changing field through contributions to this journal. thomas d. harnish editor's notes jola will continue to be interesting and useful to its readers to the extent that its readers are willing to expend the efforts to also be its writers. the authors in this issue are all as busy as you and i. they have made time in their already full schedules to write down ideas and information they hope will be useful and provocative. they and we of the ]ola staff hope you are pleased with the results . so what's new by you? how have your patrons reacted to your new online catalog? what do the costs of your acquisitions system look like? how about that idea you had about a new way to do whatever? do you think the fuss over authority control is worth it? if you have ,ideas, perceptions, or stories to tell that you feel are of interest to your fellow readers, please write and let them know. 2 information technology and libraries | march 2010 michelle frisque (mfrisque@northwestern.edu) is lita president 2009–10 and head, information systems, north western university, chicago. michelle frisque michelle frisque (mfrisque@northwestern.edu) is lita president 2009–10 and head, information systems, north western university, chicago. michelle frisque president’s message: join us at the forum! t he first lita national forum i attended was in milwaukee, wisconsin. it seems like it was only a couple of years ago, but in fact nine national forums have since passed. i was a new librarian, and i went on a lark when a colleague invited me to attend and let me crash in her room for free. i am so glad i took her up on the offer because it was one of the best conferences i have ever attended. it was the first conference that i felt was made up of people like me, people who shared my interests in technology within the library. the programming was a good mix of practical know-how and mindblowing possibilities. my understanding of what was possible was greatly expanded, and i came home excited and ready to try out the new things i had learned. almost eight years passed before i attended my next forum in cincinnati, ohio. after half a day i wondered why i had waited so long. the program was diverse, covering a wide range of topics. i remember being depressed and outraged on the current state of internet access in the united states as reported by the office for information technology policy. i felt that surge of recognition when i discovered that other universities were having a difficult time documenting and tracking the various systems they run and maintain. i was inspired by david lanke’s talk, “obligations of leadership.” if you missed it you can still hear it online. it is linked from the lita blog (http:// www.litablog.org). while the next forum may seem like a long way off to you, it is in the forefront of my mind. the national forum 2010 planning committee is busy working to make sure this forum lives up to the reputation of forums past. this year’s forum takes place in atlanta, georgia, september 30–october 3. the theme is “the cloud and the crowd.” program proposals are due february 19, so i cannot give you specifics about the concurrent sessions, but we do hope to have presentations about projects, plans, or discoveries in areas of library-related technology involving emerging cloud technologies; software-as-service, as well as social technologies of various kinds; using virtualized or cloud resources for storage or computing in libraries; library-specific open-source software (oss) and other oss “in” libraries; technology on a budget; using crowdsourcing and user groups for supporting technology projects; and training via the crowd. each accepted program is scheduled to maximize the impact for each attendee. programming ranges from five-minute lightening talks to full day preconferences. in addition, on the basis of attendee comments from previous forums, we have also decided to offer thirtyand seventy-five-minute concurrent sessions. these concurrent sessions will be a mix of traditional singleor multispeaker formats, panel discussions, case studies, and demonstrations of projects. finally, poster sessions will also be available. while programs such as the keynote speakers, lightning talks, and concurrent sessions are an important part of the forum experience, so is the opportunity to network with other attendees. i know i have learned just as much talking with a group of people in the hall between sessions, during lunch, or at the networking dinners as i have sitting in the programs. not only is it a great opportunity to catch up with old friends, you will also have the opportunity to make new ones. for instance, at the 2009 national forum in salt lake city, utah, approximately half of the people who attended were first-time attendees. the national forum is an intimate event whose attendance ranges between 250 and 400 people, thus making it easy to forge personal connections. attendees come from a variety of settings, including academic, public, and special libraries; library-related organizations; and vendors. if you want to meet the attendees in a more formal setting you can attend a networking dinner organized on-site by lita members. this year the dinners were organized by the lita president, lita past president, lita presidentelect, and a lita director-at-large. if you have not attended a national forum or it has been a while, i hope i have piqued your interest in coming to the next national forum in atlanta. registration will open in may! the most up-to-date information about the 2010 forum is available at the lita website (http:// www.lita.org). i know that even after my lita presidency is a distant memory, i will still make time to attend the lita national forum. i hope to see you there! 2 information technology and libraries | december 2008 andrew k. pacepresident’s message i n my first column, i mentioned that the lita board’s main objective is “to oversee the affairs of the division during the period between meetings.” of course, oversight requires communication. sometimes this is among board members, or it’s an e-mail update, or a post to the lita-l discussion list, or even the articles in this journal. regardless, i see the cornerstone of “between-meeting oversight” as keeping the membership fully (or even partially) engaged from january through june and july through december. as a mea culpa for the board, but without placing the blame on any one individual, i am willing to concede that the board has not done an adequate job of engaging the membership between american library association (ala) meetings. while ala itself is addressing this problem with recommendations for virtual participation and online collaboration, lita should be at the forefront of setting the benchmark for virtual communication, participation, education, planning, and membership development. in an attempt to posit some solutions, as opposed to finding someone to blame, i first thought of the lita committees. which one should be responsible for communicating lita opportunities and events to the membership using twenty-first-century technology? education? membership? web coordinating? program planning? publications? in the end, i was left with the choice of two evils: merge all the committees into one so that they can do everything or create a new committee to deal with the perceived problem. knowing that neither of those solutions will suffice, i’d like to put the onus back on the membership. maybe i’m trying to be a 2.0 librarian—crowdsourcing the problem, that is, taking the task that might have been done by an individual or committee and asking for more of a community-driven solution. in the past, lita focused on the necessary technologies for crowdsourcing—discussion lists, blogs, and wikis—as if the technology alone could solve the problem. the bigwig taskforce and web coordinating committee have shouldered the burden of both implementing the technology and gaining philosophical consensus on its use—a daunting task that can easily appear chaotic. now that the technology is commoditized (and generally embraced by ala at large and other divisions as well), perhaps it is time to embrace the philosophy of crowdsourcing. maybe it’s just because i have had cloud computing and web-scale architectures on the brain too much lately (having decided that it is impossible to serve two masters—job and volunteer work—i shall forever endeavor to find the overlap between the two), but i sincerely believe that repeating the mantra that lita’s strength is its membership is not mere rhetorical lipservice. ebay is better for sellers because there are so many buyers; it is better for buyers because there are so many sellers. googledocs works for sharing documents better than a corporate wiki or microsoft sharepoint because it breaks down the barriers of domains, allowing the participants to determine who shares responsibility for producing something. barcamps are rising in popularity not only because of a content focus on open data, open source, and open access, but because of the participatory and usergenerated style of the barcamp-style meetings. as a division of ala, lita has two challenges— leading the efforts of educating the membership, other divisions, and ala about impending sea changes in information technology, but also embracing these technologies itself. we must eat our own dog food, as the saying goes. perhaps it is more fitting to suggest that lita must not only focus on getting technology to work, but putting technology to work. in the next few months, the lita board will be tackling lita’s strategic plan, which expires in 2008. that means it is time not only to review the strategy—to educate, to serve, to reach out—but also to assess the tactics employed to fulfill that strategy. you are probably reading this column in or after the month in which the strategic plan ends, which does not mean that we will be coasting into the ala midwinter meeting. on the contrary, i sincerely hope to gather enough information from committees, task forces, members, and nonmembers in order for the lita leadership to come up with something strategically meaningful going into the next decade. one year isn’t nearly long enough to see something this big through to completion. just as national politicians begin reelection campaigns as soon as they are elected, i suspect that ala divisional presidents begin thinking about their legacy within the first couple months of office, if not before. but i hope, at least, to establish some groundwork, including a platform strategy that will allow the membership to maintain a connection with the board and with other members—to crowdsource solutions on a scale that has not been attempted in the past and that will solidify our future. and when we have a plan, you can trust that we will use all the available methods at our disposal to promote it and solicit your feedback. andrew k. pace

varnum and marisha c. kelly information technology and libraries | september 2022 https://doi.org/10.6017/ital.v41i3.15559 as summer turns to fall—too soon for the editor of this journal—the northern hemisphere’s academic calendar is getting started. after the past two years of covid-directed activities, it feels good to be returning to a more typical start to the year. while we’re not out of the pandemic woods yet, by any means, it does feel as if we’ve turned a corner. some of us have returned to precovid modes of working and socializing, while others are finding the return to the status quo ante a bit more challenging. if the pandemic has shown us one thing, it’s the power—and limitations—of technology to adapt to a changed world, and of our human ability to adapt, or not, to new habits of technology. we’ve covered many of these responses of adaptation in the pages of this journal over the past two years, and expect that many more innovations and lessons learned will be shared here in the years to come. technological change is a never-ending process. information technology and libraries will continue to share the ways cultural memory institutions adapt, respond, and react to changes in the technological tools we use. as always, if you have lessons learned about technologies and their effect on our mission, we’d like to hear from you. our call for submissions outlines the

"average" time reported for searching in card catalogs was 37.3 min-utes, in film catalogs 41.6 minutes, and for fiche catalogs 4i. 7 minutes. a reanalysis of the original data shows a stronger advantage of fiche over film (45.3 minutes versus 51.7 minutes) when all times except duplicates are totaled, but that difference is almost entirely due to one extreme score (203 minutes). 9 the berkeley report of fiche/film comparability addressed the issue of retrieval speed directly. by constructing a series of look-up tests composed of items selected from a large public library com catalog, the researchers were able to compare microfiche and microfilm formats while holding other variables constant. in one test involving thirty-six paid users and 252 trials, microfilm was determined to be faster by 7.6 percent (±2.5 percent). in a second test, forty volunteer users were timed in 240 trials and the advantage of film over fiche dropped to 5. 7 percent ( ± 2.5 percent) .1° although rigorous in design and execution, the berkeley experimenters used in their look-up tests questions that naive users might misinterpret, e.g., "you want a book about paul robeson, written by eloise greenfield. find the listing and give the call number"; and some which could be confusing, e.g., "does the library have any joke books? if so, give the call number for one. "11 such questions potentially pose an element of uncertainty for subjects: should i look under robeson or greenfield? under joke books or humor? in addition, questions were selected by "browsing the file for target items," a procedure which could result in an uneven distribution of items which in turn could bias the results. since the number of observations is relatively large the reliability of the results is not questioned; the validity may be. the study reported here was executed by a class in research methods taught by the author during the same time as the berkeley study; we used the same two formats of the same catalog, and attempted to answer the same question: using the best available equipment, which microformat is faster to search? assumptions we assumed (i) the two forms of the catalog were identical; (2) the quality of the image was not significantly different; (3) a communications 293 search for items selected randomly from the file and arranged randomly was a fair test of retrieval speed; and ( 4) graduate students in library science were reasonably representative users for a test of speed. methodology we used a dictionary catalog from a public library system with 436, 79i entries, of which 5,63i were author, ill,l58 were title or added entries, and 320,002 were subject entries. using a random number table, we selected from the catalog i6 entries which were reproduced and randomly arranged to form the test. of the i6 items, 3 were author entries, 8 were title or added entries, 5 were subject entries. the sequence, which presumably would affect the speed of retrieval more in the film format because of the necessity to scroll from one letter to another, wasacwns kcb wm h l p pal. the test was then administered to thirty-seven volunteer graduate students randomly assigned to a micro-design 4020 fiche reader or an information design rom 3 film reader. the two readers were located in the same room. the 86 fiche were held and displayed by a ring king binder. all times were measured by a stopwatch. questionnaires administered before and after the test established that the two groups did not differ significantly in age or in selfperceived mechanical ability. of the film users, 64 percent used micro-formats "occasionally" or "frequently" compared with 35 percent of the fiche users. of the total group, 73 percent wore glasses and 62 percent reported prior physical problems with both film and fiche readers used before the test. results table 1 shows that the mean speed of the film users was i6. 7 minutes, significantly faster than the 25.3 minutes recorded by the fiche users; the range of speed for the film users was less than v3 that of the fiche users. even the slowest film user was faster than 70 percent of the fiche users. however, the fastest fiche user was faster than 70 percent of the film users. the range of fiche scores is more than 3 times that of the film scores (figure i). the standard statistical test shows the difference of means to be significant at the .oilevel. 294 journal of library automation vol. 14/4 december 1981 table i. speed of retrieval (in minutes) format low microfilm (n = 17) 12.3 microfiche(c = 20) 14.6 t = 4.8,p< .01 discussion searching motorized microfilm appears to be significantly faster than searching microfiche, on the average, for relatively inexperienced users. even the slowest time on the film was faster than most fiche times. the wide range of fiche scores suggests the possibility that frequent users could improve their searching times; very experienced users may be able to search fiche faster than film. • because of the relatively small numbers of subjects and observations •the author, an experienced fiche user, was timed at 11.6 minutes; this was the fastest time recorded by either fiche or film users. <j) q) ol ~ c: q) (..) .... & standard high mean deviation 19.45 16. 7 2.34 18.0 25 .3 7.47 involved, the results should be interpreted with caution. although the advantage of film over fiche in this study is greater than that shown in the berkeley report, differences in design and analysis must be taken into account. acknowledgments the author wishes to acknowledge the members of his research methods class, especially david fishbaugh and carol manoukian, for their assistance. references 1. bath university comparative catalog study : final report. papers no. 110. i film n•20 ~ fiche n•l7 time in minutes and tenths fig. i. dislribulionsojtest scores.

(all but three agencies were using ibm 360/370 equivalent computersthe parallel is clear.) computer usage as noted, all but three agencies use ibm equivalents in the mainframe range; three of those use plug-compatible equipment such as magnuson and amdahl. the other major computers are cdc, dec/vax, and data general eclipse systems. smaller computers in use include dc, dec 11170, datapoint, and ibm series/! units. home terminals and computers four of those present currently have home terminals. three have home computers. future plaru for the discussion group the midwinter 1982 topic will be "holdings," with some emphasis on dealing with holdings formats in various technical processing systems (such as oclc, utlas, wln, rlin). an announcement and mailing list will go to all those on the mailing list, as will an october/november mailing with questions sent to the chair. those interested should send their names and addresses to walt crawford, rlg, jordan quad, stanford, ca 94305. it is anticipated that papers on the topic may be ready by midwinter; questions and comments are welcomed. note: there will be no set speakers or panelists; this will be a true disci.i.i'sion group. the topic for the philadelphia meeting will be set at midwinter 1982.-walt crawford, chair, the research libraries group, inc. channel 2000 a test of viewdata system called channel 2000 was conducted by oclc in columbus, ohio, during the last quarter of 1980. an outgrowth of the oclc research department's home delivery of library services program, channel 2000 was developed and tested to investigate technical, business, market, and social issues involved in electronic delivery of information using videotex technology. data collection throughout the test, data were collected in three ways. transaction logs were maintained, recording keystrokes of each user during the test, thus allowing future analyses and reconstruction of the test sessions. questionnaires requesting demographic information, life-style, opinion leadership, and attitudes toward channel 2000 were collected from each user in each household before, during, and after the test. six focus-group interviews were held and audiotaped to obtain specific userresponses to the information services. attitudes toward library services forty-six percent of the respondents agreed that channel 2000 saved time in getting books from the library. responding to other questions, 29 percent felt that they would rather go to a traditional library than order books through channel 2000, and 38 percent of the users felt that channel 2000 had no effect on their library allendance. forty-one percent of the channel 2000 test group felt that their knowledge of library services increased as a result of the channel 2000 test. in addition, 16 percent of the respondents stated that they spent more time reading books than they did before the test. eighty-two percent of the respondents felt that public libraries should spend tax dollars on services such as channel 2000. although this might suggest that library viewdata services should be taxbased, subsequent focus-group interviews indicated that remote use of these services should be paid for by the individual, whereas on-site use should be "free." sixtythree percent of the test population stated news and announcements 237 that they would probably subscribe and pay for a viewdata library service, if the services were made available to them off-site. purchase intent respondents were asked to rank-order the seven channel 2000 services according to the likelihood that they would pay money to have that service in their home. a mean score was calculated for each channel 2000 service, and the following table shows rank order of preference. rank order channel 2000

software available at the 1981 ala annual conference in san francisco, the northwestern univer238 journal of library automation vol. 14/3 september 1981 sity library announced the availability of version 3.2 of the notis computer system. intended for medium and large research libraries or groups of libraries, notis provides comprehensive online integratedprocessing capabilities for cataloging, acquisitions, and serials control. patron access by author and title has been in operation for more than a year , and version 3.2 adds subject-access capability as well as other new features. an improved circulation module and other enhancements are under development for future release. although notis, which runs on standard ibm or ibm-compatible hardware, has been in use by the national library of venezuela for several years, northwestern only recently decided to actively market the software, and provided a demonstration at the ala conference. a contract has been signed with the university of florida, and several other installations are expected within a few months. further information on notis may be obtained from the northwestern university library, 1935 sheridan rd.,

bibliographic access & control system (bacs). the system is now in operation and utilizes marc cataloging records obtained from oclc since 1975, serials records from philsom serials control network, and machine-readable patron records. features of interest in the system are: 1. patron access by author, title, subject, call number, or combination of keywords. the public-access feature has been in operation since may 1981. online instructions support system use, minimizing staff intervention. user survey indicates a high degree of satisfaction with the system. 2. low cost public access terminal with a specially designed overlay board. 3. barcode-based circulation system featuring the usual functions, including recalls for high demand items, overdue notices, suspension of circulation privileges, etc. 4. cataloging records loaded from oclc marc records by tape and from a microcomputer interface at the oclc printer port. authority control available on three levels: (a) controlled authority, i.e. , mesh or lc, (b) library-specific assigned authority, and (c) word list available to user. 5. full cataloging functions online, including editing, deleting, and entering records. 6. serials control from philsom system. philsom is an online distributed computer network that currently controls serials for sixteen medical school libraries. philsom features rapid online check-in, claims, fiscal control, union lists, and management reports. 7. five possible displays of the basic bibliographic record, varying from a brief record for the public access terminal to complete information for cataloging and reference staff. 8. two levels of documentation available online. the software is available to interested libraries, bibliographic utilities, or commercial firms.

editorial board thoughts: developing relentless collaborations and powerful partnerships mark dehmlow information technologies and libraries | june 2017 3 with the end of the performance and fiscal year wrapping up, it seemed like a good time to reflect on what change initiatives we have engaged in over the past few years that have strengthened the organizational effectiveness of the it department in our library. my thoughts almost immediately drifted to our focus on collaboration. early in my career, it was the profession wide culture of cross-institutional collaboration that convinced me that becoming a librarian would be the right career move. i am certain that the impetus to collaborate stems from our professional service commitment a values based system that at its core believes that the success of all helps the collective do their jobs better in the name of service to our patrons. and yet, over the years, i have heard stories of and observed first hand internal competitions for resources, vilification of library it as siloed and opaque factions, and library it departments that have had strained relationships with their institution’s central it organizations. as a part of our senior leadership team for the hesburgh libraries, two of my core professional interests are organizational effectiveness and staff satisfaction, especially in the face of a rapidly changing technology landscape, competition for talent in the it sector where it is hard to contend with commercial salaries, and the slow rate of attrition at the university. retaining talented it staff requires creating a work culture that is better than the commercial sector, a work culture that values work/life balance, innovation and experimentation, a culture of teamwork and camaraderie, and where there is a clear sense of strategic priority. to build these latter two qualities into our work culture, we have strategically emphasized durable internal and external coalitions with a tenacious sense of partnership. true collaboration reinforces a collective sense of goals, allows for maximal efficiency, discourages unnecessary or destructive competition, and opens the door to the coveted but seldom realized ability to “stop doing” through partnering with other units on campus that share a sense of priority around particular services. creating sustainable and significant internal collaboration requires etching it into the culture of the organization. making it a part of the organization’s dna has to be prioritized and modeled by senior leadership and it begins with advancing shared goals over singular agendas. in our senior leadership team, we have committed to each other as our primary team. we may advocate for staff and initiatives in our own verticals, but our drive is to be holistic stewards for the libraries, not just our functional departments. we give as much, if not more weight, to the objectives of collective senior leadership team which also helps in clarifying priorities. our executive leadership mark dehmlow (mdehmlow@nd.edu), a member of the ital editorial board, is director of library information technology, hesburgh libraries, university of notre dame, south bend, in. editorial board thoughts | dehmlow https://doi.org/10.6017/ital.v36i2.10044 4 models cooperation, cross-divisional problem solving, and collective strategic initiative planning. using this model, decisions get made more quickly, enhancing our ability is to accomplish things on time with a high level of quality, and with a considerable level of satisfaction for our staff and faculty. the it department is less viewed as a black box where decisions for what to work on are made behind the curtains and rather as a group of talented staff who help our organization accomplish their priorities. when our it department needs to advocate for support and timely completion of work from individuals in other departments, the other senior managers help get their units mobilized. we see ourselves as part of the community and the community embraces us as part of them. historically, it has been tempting to view it as somewhat separate a part of the production line, but in an age where every operation in the library is affected by technology, our workflows need to be more integrated and team based. the problems we are working on are more cross-disciplinary and require a plurality of expertise to solve. libraries are increasingly becoming more and more of an interconnected and interdependent ecosystem that requires thinking holistically about problems and a relentless commitment to building coalitions to drive our services. it may seem obvious that this would be a more effective way to work, yet i have spoken with many people at organizations where there is a clear culture of departmental objective separation and competition for resources. i have long appreciated the the work environment at notre dame, in part because we strive to be an organization whose culture has been guided by our core institutional values accountability, integrity, excellence in leadership, excellence in mission, and teamwork. these values not only drive our internal collaborations, but also the way in which different departments on campus work with each other. we have had a long standing, positive relationship with our central office of information technologies one that has been tremendously cooperative, but for many years has lacked interconnections at a variety of levels and a clear collaborative and strategic focus. in the last 5 years, our organizations have shifted their focus the oit from emphasizing centralized, administrative, enterprise computing to decentralized, academic, enterprise computing and the libraries from doing everything in house to leveraging services for standardized services and focusing our staff’s time on initiatives where they can create the most value. in part, we developed an in-house it department because we had service expectations that weren’t a priority at the time for the oit. but during our strategic transitions, we have extended our working relationships at every level throughout our organizations from our staff in the trenches to our managers and senior leaders. my focus as the director for library it over the past few years has been to look at ways we can enhance our capacity through partnerships. to that end, there are several interrelated initiatives that we have begun to engage in with the oit: 1. embedding an oit presence in the libraries 
 2. shifting support for common it services to the oit, and 
 3. consolidating our customer communication through their service portal servicenow. 
 information technologies and libraries | march 2017 5 the first step in this new collaboration with the oit was letting go of the past and revisiting where the oit and the libraries have strategic overlaps that may not have been aligned before. as two service organizations on campus with a deep concern for supporting the academic endeavor, it was easy to find strategic alignment with each other. for the libraries, we often get questions at our service points about how to change passwords or install printer drivers, needs that are part of the central it service portfolio. for the oit, the libraries are a major campus hub where hordes of students and faculty conduct research and work on assignments, particularly after classes when many of the business unit leave the university for the day. working closely with the libraries’ director for teaching, research, and user services and the oit’s senior director for user services, we began developing a collaboration grounded in our common desire to support end users which resulted in creating an oit outpost in the libraries. while there are many libraries who have this kind of collaboration, this was a revolutionary step for us. this collaboration opened the door for us to begin a discussion about common technology services that we have been supporting internally printing and general lab computing. for us, these services are important to function well for our end users, but they are not services that require library expertise to accomplish. the oit supports these services for much of campus and as long as we have aligned expectations around service level expectations that are practical and committed to excellence the oit can handle that function much more efficiently and we can use our staff expertise to support other, emerging services that are core to the libraries. we are also working closely with the oit to leverage their it service portal servicenow as the libraries’ service portal. given that our service portfolio is much broader than strictly it services, moving in this direction for us required a willingness from the oit to think outside of the box and allow us to customize the system to meet our service needs. it has required some reciprocation from the libraries as well. the servicenow platform is more expensive than others we could license, its functionality will require effort from our staff to customize, and it is requiring us to change workflows, especially in the public services areas. integrating our customer communication into this platform, though, will create a better user experience for our patrons through supporting a common interface they are experienced with and it will allow for us to more easily transfer both staff and patron general it questions to the oit. beginning to work in truly collaborative ways requires shifting the narrative around our relationships from a client/provider model to one of a coalition. redefining these relationships as partnerships puts both parties on equal footing around the planning table where everyone has an equal stake in the objectives and outcomes. they don’t come effortlessly, they require libraries to ardently become more visible on campus, to articulate the complementary value that we can contribute to campus initiatives, and to proactively request to join initiatives that we haven’t participated in before. it also takes reaching out and helping campus partners see how we can collectively create value together using our unique talents to successfully support the campus community. and lastly, it takes engaging a more holistic view of the university and the way we steward its resources; sometimes that will mean allocating more resources for the common good editorial board thoughts | dehmlow https://doi.org/10.6017/ital.v36i2.10044 6 versus taking the narrower view that we should only consider our own context when adopting solutions. but in the end, if we are willing to think about our role at the university in that broader context and build powerful partnerships, we will collectively be able to serve our end users better. lib-mocs-kmc364-20131012113204 194 journal of library automation vol. 14/3 september 1981 today's large academic libraries struggle, there is, nonetheless, room for criticism of library priorities. this study must be viewed as only a first step (largely tentative and exploratory) in relating automation with service attitudes. it suggests that online systems may be associated with managers more positive in their view of the management role and more positive in their attitudes toward users than batchand manual-system managers. further research would be useful at this point to compare levels of automation (manual, batch, and online) with circulation-staff service attitudes or those of patrons using the systems. references l. laurence miller, "changing patterns of circulation services in university libraries" (ph.d. dissertation,

mccallum and james l. godwin: network development office, library of congress, washington, d.c. in designing an automated system, it is important to understand the characteristics of the data that will reside in the system. work is under way in the network development office of the library of congress (lc) that focuses on the design requirements of a nationwide authority file. in support of this work, statistics relating to headings that appear on the bibliographic records in the lc marc ii files were gathered. these statistics provide information on characteristics of headings and on the expected sizes and growth rates of various subsets of authority files. this information will assist in making decisions concerning the contents of authority files for different types of headings and the frequency of update required for the various file subsets. then ational commission on libraries and information science supported this work. use of these statistics to assist in system design is largely system-dependent; however, some general implications are given in the last section of this paper. in general , counts were made of the number of bibliographic records, headings that appear in those records, and distinct headings that appear on the records. the statistics were broken down by year, by type of heading, and by file. in this paper, distinct headings are those left in a file after removal of duplicates. distinctness will not be used to imply that a heading appears only once in a source bibliographic file, although distinct headings may in fact have only a single occurrence. thus, a file of records containing the distinct headings from a set of bibliographic records is equivalent in size to a marc authority file of the headings in those bibliographic records. methodology these statistics were derived from four marc ii bibliographic record files maintained internally at lc: books, serials, maps, and films. the files contain updated versions of all marc records that have been distributed by lc on the books, serials, maps, and films tape:; frum 1969 through october 1979, and a few records that were then in the process of distribution. the files do not contain cip records. a total of l ,336,182 bibliographic records were processed, including 1,134,069 from the books file, 90,174 from the serials file, 60,758 from the maps file, and 51,176 from the films file. a file of special records, called access point (ap) records, was created that contains one record for the contents of each occurrence of the following fields in the bibliographic records: type of heading personal name corporate name conference name topical subject geographic subject uniform title heading fields 100,700,400,800,600 110,710,410,810,610 111,711,411,811,611 130, 730, 650 651 830,630 only the 6xx subject fields that contained lc subject headings (i.e., second indicator = 0) were selected asap records. the main entry data string was substituted for the pronoun in the series (4xx) fields that contained pronouns. the ap records also contained information from the bibliographic records that assisted in making the counts, such as the date of entry of the record on the file, the identity of the type of bibliographic file, and the language of the bibliographic record. a third file was derived from the ap file that contained a normalized character string for each ap record heading. these normalized ap records were used to produce the counts of distinct headings by clustering like data strings. normalization included conversion of all characters to uppercase, and masking of diacritics, marks of punctuation, and other characters that do not determine the distinctness of a heading, but would interfere with machin~ determination of uniqueness. the subhelds included in the normalized string, hence used for all heading comparisons, are given below. only use-dependent subfields, such as the relator subfield, and those that belonged to title clusters in author/title headings were excluded. examples of the ap file field contents and the normalized forms are: ap field contents: chuang-tzu chuang-tzu [blaeu,joan] 1596-1673 blaeu, joan. 1596-1673

byron, baron, 1788.1824 communications 195 normalized forms: chuang tzu blaeu joan 1596 1673 byron george gordon noel byron baron 17881824 distinct headings for this study were determined by comparing on the following subfields: type of heading personal name corporate name sub fields a, b,c,d a, b, k, f, p, s, g conference name a, q, e topical subject a, b, x, y, z geographic subject a, b, x, y, z all occurrences of repeating subfields were included. the relator data of subfields were dropped from personal and corporate name headings as were the title subfields in author/title headings. a separate study will examine the occurrence of author/title headings. approximately 8 percent of the name headings in the files carry title subfields: 6 percent are series and 2 percent are author/title subjects or added entries. two types of distinct heading counts were generated for topical and geographic subject headings. one takes account only of main terms, the a and b subfields, excluding all subject subdivisions. the other compared the complete heading strings, including subject subdivisions. characteristics of the files the four bibliographic files from which the statistics were derived were begun in different years and are of unequal size. table 1 presents the number of bibliographic records added to each of the marc files by the year that the record was first entered into the file. the records added in the first months of 1979 have been eliminated from tables 1-3, thus the total number of records under consideration is 1,210,809. in the combined file, the records for books dominate the contributions from other forms of materials, representing 85 percent of the combined file records. after the addition of the films and serials records in 1972 and 1973 the total number of records added each year leveled off to around 115,000 but jumped to an average of slightly more than 150,000 records per year following the ad196 journal of library automation vol. 14/3

languages since 1969 and only a limited number of non-english-language audiovisual materials are cataloged. the unusually large number of records added to the books file in 1971 resulted from a special project to add retrospective titles to the file. the large increase in books records in 1978 was due to the co marc project in which retrospective lc records that had been converted to machine-readable form by other libraries were contributed to the lc marc file. approximately 12,000 comarc records were added in 1977 and 28,000 in 1978. the fall in numbers of film records produced in 1976-1978 reflects a general fall in production of instructional films in the united states. counts of items cataloged that are compiled by lc processing services from catalogers' statistics sheets show that lc cataloged approximately 225,000 titles in 1978; thus, approximately 73 percent of lc cataloging is currently going into machinereadable form. the principal exclusions are records for most nonroman material (only nonroman records for maps have been transliterated and added since 1969) and a few records for music, sound recordings, incunabula, and microforms. the portion being put into machine-readable form should rise significantly as the romanized records for items in several nonroman alphabets are added in the next year. name headings table 2 presents the number of occurrences of name headings in the marc bibliographic files and the number of distinct name headings, both by type of heading and by year. the number of distinct headings that were new to the file in a year was determined by comparing the headings added in a given year against those added in all previous years. it is not surprising to find that 66 percent of name-heading occurrences are personal names, 33 percent are corporate, and only 1.4 percent are conference. the figures shift when considering the distinct names, where 77 percent are percommunications 197 sonal and only 21 percent are corporate. looking at ~he total figures in table 2, while 1 ,308,193 of the headings that appeared on the records were personal names, only 633,048 or 48 percent of these were distinct. of the rest, 52 percent were duplicates of the distinct headings. similarly, 26 percent of corporate names were distinct, with 74 percent being duplicates; and 71 percent of conference names were distinct, with only 29 percent being duplicates. in 1968, 87 percent and 68 percent of personal and corporate names, respectively, were distinct, i.e., 13 percent and 32 percent "had been used previously" when they appeared on a bibliographic record during the year. as the base file of names grows, the percentage of names appearing on new records but which "had been used previously" rises, to 60 percent and 77 percent in 1974. while the figures reported in table 2 indicate that the percentage of headings used that were repeats fell slightly again in 1977 (51 percent and 73 percent), this is probably due to the influx of new names with the addition of new languages in 1976-77. additional statistics gathered on english-language items show the percentage of repeating headings becoming steady after 1974. subject headings statistics concerning distinct topical and geographical subject headings were collected for main terms, excluding subdivisions, and for full subject heading strings. table 3 gives the numbers of headings and the numbers of distinct headings of each type found in the marc file. looking at the total figures, only 4.8 percent of topical first terms are distinct, the rest are duplicates. this indicates an average occurrence of 20.8 times for each first term. slightly more, 12 percent, of the geographic first terms are distinct. when the full headings with topical, period, form, and geographic subdivisions are considered, the percentage of headings that are distinct rises to 32.3 percent for topical subjects and 38.8 percent for geographic subjects. thus, 67.3 percent of topical and 61.2 percent of geographic are duplicates of existing headings. in the yearly figures, sub198 journal of library automation vol. 14/3 september 1981 ject headings show the same tendency as name headings in that the percentages of headings that appear on new records but which "had been previously used" rises as the stock of headings increases and then levels off. subjects were also affected by the addition of other roman alphabet languages in 1976-77 but not to a very large degree. for all access points, name headings and full string subject headings, name headings account for 55 percent of the headings that occur in the bibliographic records, with only 45 percent attributable to topical and geographical headings. it should be noted that 12 percent of the name headings that appear on the bibliographic records are names used as subjects. frequencies of occurrence counts were also made of the frequency with which name headings occurred in the bibliographic files. table 4 summarizes the frequency data: 66 percent of distinct personal names, 62 percent of distinct corporate names, and 84 percent of distinct conference names occur only once in the files. the percent of corporate names with single occurrences is surprisingly close to that for personal; however, the percent of names having multiple occurrences falls more slowly for corporate than for personal names. while 5.47 percent of corporate names occur ten or more times, only 1.92 percent of personal names occur ten or more times. the figures for personal names roughly correspond to those obtained by william potter from a sample taken from the main catalog at the university of illinois at urbana-champaign. that study showed 63.5 percent of personal names occurred onlyonce. 1 the number of occurrences of different types of headings are compared in figure 1. the bars show the numbers of personal, corporate, conference, topical, and geographic headings that appear in the bibliographic files. the shaded areas represent the number of headings that are distinct, thus the upper part of each bar represents additional occurrences of the headings from the shaded area. for personal, corporate, and conference headings a further distinction is made between distinct headings that occur only once, the crosshatched area, and those that have multiple occurrences. thus the multiple occurrences of corporate names may be seen to come from a small table 4. frequency of occurrence of name headings in all files distinct distinct distinct number of personal names corporate names conference names

useful in making decisions on the addition of retrospective authority records to the automated files. reference 1. william gray potter, "when names collide: conflict in the catalog and aacr2," library resources & technical services 24:7 (winter 1980). rlin and oclc as reference tools douglas jones: university of arizona, tucson. the central reference department (social science, humanities, and fine arts) and the science-engineering reference department at the university of arizona library are currently evaluating the oclc and rlin systems as reference tools, to see if their use can significantly improve the effectiveness and efficiency of providing reference service. a significant number of the questions received by our librarians, and presumably by librarians elsewhere, incommunications 201 volve incomplete or inaccurately cited references to monographs, conference proceedings, government documents, technical reports, and monographic serials. if by using a bibliographic utility a librarian can identify or verify an item not found in printed sources, then effectiveness has been improved. once a complete and accurate description of the item is found, it is a relatively simple task to determine whether or not the library has the item, and if not, to request it through interlibrary loan. additionally, if the efficiency of the librarian can be improved by reducing the amount of time required to verify or identify a requested item, then the patron, the library, and, in our case, the taxpayer, have been better served. the promise of nearimmediate response from a computer via an online interactive terminal system is clearly beguiling when compared to the relatively time-consuming searching required with printed sources, which frequently provide only a limited number of access points and often become available weeks, months, or even years after the items they list. we realize, of course, that the promise of instantaneous electronic information retrieval is limited by a va):'iety of factors, and presently we view access to rlin and oclc as potentially powerful adjuncts tonot replacements for-printed reference sources. given that rlin and oclc have databases and software geared to known-item searches for catalog card production, our evaluation attempts to document their usefulness in reference service. a preliminary study conducted during the spring semester of 1980-81 indicated that approximately 50 percent of the questionable citations requiring further bibliographic verification could be identified on oclc or rlin. the time required was typically five minutes or less. successful verification using printed indexes to identify the same items ranged from 20 percent in the central reference department to 50 percent in science-engineering. time required per item averaged approximately fifteen minutes. based on our findings, we plan a revised and more thorough test during the fall semester of 1981-82, which will include an assessment of the

purchased digital systems over the years, including digital collection platforms, institutional repositories, and other online tools on which users depend. at hesburgh libraries, as with other institutions, some of these systems have aged without strong guidance and resulted in stale services and technology. this case study will explore the lengthy process of stewarding an aging service that satisfies critical external needs. starting with a brief literature review and institutional context, the authors will examine how the current product owners have embraced the role of maintainers, charting a future direction by defining a clear vision for the service, articulating firm boundaries, and prioritizing small changes. the authors will conclude by reflecting on lessons learned and discussing potential future work, both at the institutional and professional level. introduction our home-grown institutional repository (ir) began almost a decade ago with enthusiasm and promise, driven by an eagerness to meet as many use cases as possible. over time, the code grew unwieldy, personnel transitioned into new roles, and new priorities emerged, leaving few individuals to manage the repository, allocate resources, articulate priorities, or advocate for user needs. this in turn left the system underutilized and undervalued. in mid -2019, two product owners (pos) at hesburgh libraries, university of notre dame were named to oversee the service and tasked with determining how the service should continue, if at all. the pos began by evaluating the service, current commitments, and benefits, and identifying potential on-campus adopters of the service. after agreeing the service should continue, the pos started the lengthy process of turning the metaphorical ship, prioritizing modest adjustments that would have large payoffs.1 selected literature review since the 2003 seminal article by clifford lynch, much has been authored on the topic of institutional repositories as academic libraries and archives have flocked to create their own.2 a complete literature review is beyond the scope of this case study: institutional repositories have contended and continue to contend with a wide variety of challenges, including legal, ethical, and socio-technical challenges.3 while the lessons presented in this case study can apply to a wide variety of legacy services, a brief overview of some of the literature surrounding irs is crucial to understanding the challenges the authors were presented as product owners. broadly defined “as systems and service models designed to collect, organize, store, share, and preserve an institution’s digital information or knowledge assets worthy of such investment,” libraries and archives flocked to build the “essential infrastructure for scholarship in the digital mailto:mnarlock@nd.edu mailto:dbrower@nd.edu information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 2 age.”4 operating under the assumption that faculty members would flock to the service to deposit their works, irs were promised to solve many problems, including supporting open access publishing and digital asset management.5 as articulated by dorothea salo, however, the field of dreams model (“build it and they will come”) was insufficient as repositories often failed to meet changing user needs and expectations while heavily employing library jargon that was foreign to faculty members.6 moreover, as identified by kim, some irs struggle to even be known to their users, while also grappling with concerns of trust.7 other problems that have plagued repositories include limited adoption rates, restricted resources to support digitization of analog materials for faculty that operate in both analog and digital media, failing support from fellow library colleagues, and inconsistent and incomplete metadata.8 salo warned more than a decade ago that high-level library administrative support would be necessary to empower repository managers to enact lasting and substantive change, and recent studies echo these concerns.9 libraries have slowly started to serve faculty on their terms, such as by creating automated processes for populating irs, streamlining content deposits, experimenting with metadata harvesting features to provide increased access, and building more tools to integrate directly with the research lifecycle.10 however, these new technologies and services may be out of reach for many institutions. in addition to limited resources, some institutions are grappling with a legacy system that is incompatible with newer code, leaving these institutions in a feature desert, reliant on aging technology and cumbersome deposit processes.11 moreover, even in an institution where resources might be more readily available for licensing or purchasing newer technology, early forks of open-source code or otherwise deprecated components might make migration to newer platforms extremely difficult, if not impossible, without extensive infrastructure improvements. lastly, as libraries grappled with some of the issues mentioned above and options for repositories continued to proliferate, many institutions struggled to clearly articulate boundaries around their digital library holdings. confusion between digital collections, scholarly content, e-resources, and other digital materials resulted in some institutions having too many options to store content, leaving internal and external stakeholders confused as to where to discover and distribute materials; conversely, other institutions have few options, and a wide variety of content is pigeonholed imperfectly into a single repository.12 in both situations, developing repositories with vague content scopes can be exceedingly difficult, as a restrictive scope can stifle development , while an overly inclusive approach results in too many use cases and competing stakeholder interests to effectively prioritize feature development. local context our institutional repository at the university of notre dame, managed by hesburgh libraries employees, suffered from many problems that affected our locally built code: limited adoption and awareness on campus; aging technology that made adding new features a monumental, if not impossible, task; and an overly broad scope (and a simultaneous proliferation of other digital collection tools). while the detailed history of this repository is beyond the scope of this paper, a brief overview of the development provides critical context. additionally, the technical details and implementation particulars will not be discussed, as this case study transcends specific software frustrations and will resonate with many institutions regardless. information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 3 in 2012, after a failed attempt to launch a repository in the early 2000’s, consortial development of our ir began in an open-source community. in 2014, an early implementation of the product was envisioned to be a unified digital library service that would provide support to many different stakeholders. this included a plan for a single location for researchers to share their scholarly work, research outputs, and research data, as well as for the university libraries to provide access to digitized rare and archival holdings. as development continued on the homegrown service, features were implemented to serve the numerous purposes mentioned above. this included components of an institutional repository, such as a self-deposit interface, customizable access levels, and a proof-of-concept researcher profile system. over time support for browsing digital collections was added, namely the development of the work type “collection,” which allowed curators to create a landing page for their collection and customize it with a representative image. development continued in a somewhat sporadic fashion, often aligning at the intersection of “what is easy?” and “what is needed?” as technical staff continued growing the open-source code. as content was added to the system, stemming from special collections, various campus partners, and electronic thesis and dissertation (etd) deposits, additional use cases emerged and were added to the scope of the repository. the system quickly grew cumbersome and difficult to work with. in short, the repository struggled with the challenges of many open-source technologies. the struggle was compounded by decreasing resources, an overly inclusive scope, limited adoption— both with external faculty as well as library faculty and staff—and consortial development that introduced features extraneous to local campus needs. while our repository did many different things, it failed to do any one well. after falling short of meeting the expectations for digital collections, particularly with regards to browsing and displaying objects, the library applied for, and received, a three-year mellon grant.13 this grant, a collaboration with the snite museum of art, university of notre dame, was initially sought to improve upon the existing repository and to build the infrastructure necessary to support the online display of collective cultural heritage materials and facilitate serendipitous discovery for patrons. however, soon into the grant, it became clear that creating an entirely new system for digital collections would be not only easier to build and maintain, but also better suited to meet the specific needs of digital collections as articulated by campus partners. first things first: what is our ir? around the same time this shift was announced, two individuals were appointed to serve as product owners (pos) of the repository. while exact duties vary between institutions, pos are responsible for liaising with users, managing the product backlog, directing development, communicating with a wide variety of stakeholders, resolving issue tickets, and guiding the overall direction of the product.14 the pos were tasked with making this amorphous, oft-critiqued service usable while dealing with uncertain resources and competing institutional priorities. with the change in grant objectives mentioned above, namely the desire to develop a new repository instead of contending with the legacy code, the option was presented to retire the repository and direct users to other systems that could sufficiently meet their needs, such as discipline specific repositories, general purpose repositories, or even online cloud storage. the pos recognized that continuing the system due solely to sunk costs was a fallacy: if the service was too cumbersome to information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 4 maintain with even nominal use, the return on investment would be abysmal and ultimately prevent the library from investing resources more appropriately. in order to evaluate the service, the pos considered active commitments and ongoing partnerships tied to the service. in particular, several centers and departments on campus had utilized the system to capture citations and demonstrate their impact. additionally, after conversations with library liaisons, it became apparent that there was great value in providing the campus with a discipline-agnostic repository that allows deposition of, provides access to, and preserves scholarly outputs that might otherwise be lost. while the pos recognized that faculty adoption or even awareness of the service was limited, they realized there were several campusspecific features that were useful to local champions, including flexible access controls at the record and file levels, as well as a customized etd workflow that served the graduate school, internal technical services, and the students and faculty required to interact with the system. acknowledging that the system and related services were still critical, the pos prioritized making sure the system remained useful: maintaining the legacy repository would cost valuable time and resources and would need to overcome the resentment that many internal stakeholders had developed over the years. after deciding the system was worth maintaining, it was necessary to explicitly narrow the scope of the service, which had broadened over time in an ad hoc manner: as other services were turned off, leaving various digital content to find a new location, our institutional repository was often leveraged to host the content, even when support for the needs of niche content was poor at best. when considering the future of the repository, several key use cases emerged, including the etd support provided to the graduate school as mentioned above. while the service had done many things acceptably, the strength was in the support for scholarship: the customized access levels, self-deposit interface, and robust preservation capabilities were frequently lauded as the highlights of the service to internal and external stakeholders. these considerations, combined with the eventual migration of digitized rare and unique materials to the new mellon-funded platform, resulted in rebranding and redefining the service as exclusively focused on scholarly outputs. with the goal of best supporting the teaching and research mission of the university, the directional force became how to (re)build the service as a trusted, useful, and integral repository for campus scholars to provide access to their research outputs. mission (and vision) critical operating under the guiding principles of usefulness, usability, and transparency, the first task after redefining and rearticulating the scope of the service was to keep the service operational. however, with the recognition that maintenance alone, while critical, would not lead to an enhanced reputation on campus, it was important to continue charting a forward direction. the product owners were given the freedom to articulate their ideal mission statement. to complement the vision of the repository as both trusted and integral, the pos further defined the mission statement in three key areas: to increase the impact of campus researchers, scholars, and departments; to advance new research by facilitating access to scholarship in all forms; and to serve as active campus partners in the research lifecycle. while these statements are far from innovative or revolutionary, it was essential for moving the service forward. in fact, these sentences were carefully crafted over the course of a month, during which time the product owners drafted the language, compared it with peer and aspirational peer information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 5 institutions, and solicited feedback from trusted internal colleagues before sharing it more broadly. this time-consuming process was critical for success, however: with the knowledge that these words would serve as the foundation for prioritizing feature requests and advocating for resources, the pos wanted to establish both the repository and themselves in their new role. this clarity in mission was also important for grappling with legacy emotional and mental frustrations that lingered towards the system, as the pos had a strong, unified foundation to advocate for resources and the service as a whole. relatedly, these mission and vision statements provided critical and consistent talking points, which were leveraged in presentations to internal stakeholders, provided to librarians as messaging for the liaison faculty, and useful in short communications to teaching professors, research faculty, and department administrato rs. clear and present boundaries in rebranding the repository, it also became clear that firm boundaries would be instrumental in attaining success. in addition to narrowly focusing feature development on supporting research and scholarly outputs, the pos also scaled back goals for adoption, intentionally excluded digital collection features, and identified features that were patently unattainable in the short term. the repository was often seen as a failure locally due to limited adoption and an incomplete record of the academic outputs of campus, reflecting concerns of irs more generally.15 combatting this narrative required a clear articulation and acceptance of the fact that the institutional repository, regardless of how seamlessly integrated or easy to use, would never be absolutely comprehensive or the authoritative record of our researchers and scholars. with limited resources and a current technical infrastructure in which it is difficult to incorporate automatic harvesting mechanisms, any effort to make the repository comprehensive would be impractical, unrealistic, and a waste of limited resources. instead, by focusing efforts on making the repository useful and refraining from being yet another requirement for an already overwhelmed faculty member or graduate student, the service can be improved to meet the unique needs of campus faculty, serving as a more viable option for those who need it.16 similarly, because there is less concern with filling the repository and increasing usage statistics and more on what the patron needs, the pos have been able to develop robust partnerships with stakeholders, leading to champions in research centers, labs, departments, and other administrative units across campus. this has helped scholars demonstrate the impact of their work, which in turn led to more partnerships with other campus centers, as champions began to advocate for the service to colleagues facing similar challenges across the university. in this way, decreasing the effort to fill the repository has actually increased holdings and driven more traffic to the site: by focusing on useful offerings and decreasing the burden on ourselves to create a comprehensive research repository, the pos have been able to prove the value of a discipline-agnostic approach to internal and external stakeholders. an additional, and extremely beneficial, boundary was intentionally excluding library-owned digital collections from the repository’s collecting and feature-development scope. the pos received little pushback from internal users on this change: the repository had been the de facto scholarly and research repository for nearly five years, as it was patently clear that supporting digital collections had been more of an afterthought, with limited features built to support curators and users in creating and interacting with rare and archival materials. in fact, internal colleagues supported this change wholeheartedly, as the pos volunteered to continue providing access to the extant digital content in the ir as the mellon grant-funded site was built. while this information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 6 direction had already been understood by individuals across the organization, it was helpful to clearly articulate the new boundaries in open forums for internal stakeholders, communication through a library-wide listserv, and repetition in smaller meetings. by articulating this new boundary clearly and repeating it frequently in different methods of communication, the pos had the authority to reject feature requests that were explicitly in support of rare and archival materials. with a clear focus on collecting and providing access to scholarly and research outputs, niche metadata fields, advanced browsing features, and robust collection landing pages were identified as unnecessary, as they were scoped for the mellon-funded platform, and internal colleagues quickly embraced this boundary. the final, crucial boundary, also related to feature requests, was to clearly define requests that were impossible to accommodate in the current technical infrastructure. as mentioned earlier, the pos focused first on maintenance: by updating code, critically evaluating the service and existing commitments, and charting a future direction, the pos could more effectively steward the project. this also meant revisiting previous feature requests, and even technical promises, in order to set more reasonable expectations on what the service would, and would not, be able to support in the coming years. with limited resources, advanced features such as research profiles—a frequent request from internal allies—was beyond the current capabilities with the aging technical stack. moreover, a feature-rich repository would be essentially useless if users’ basic expectations were left unmet: a cumbersome deposit interface, limited upload support, and confusing language throughout the site were more pressing issues, as they prevented users from even engaging with the site for any amount of time. by resolving these limitations and generating awareness of the repository, the pos could better serve not only current campus partners, but also future users, as an increase in adoption and use would lead to more resources to develop advanced features. instead of planning a new outfit for the proverbial patient, it was more important to stop the bleeding. by adopting firm boundaries, the pos were able to scope developer work, prioritize maintenance and modest feature development, and even deny implementation of previously requested features that were no longer relevant to the repository or would be unattainable in the coming years. the pos could explicitly drop support for unused services, allow other services to limp along, and improve existing strengths. this has further helped to clarify messaging about the service and garner more support from our campus partners; instead of a malleable system that fits too many roles in a limited capacity, the pos could clearly state how the repository offers support and garner users from across campus. small changes, big rewards the last critical component of rebranding and revitalizing the institutional repository was the conscious decision to implement incremental improvements instead of large, sweeping changes. in particular, there were known frustrations with the service that were easy to start working on while the product owners expanded the user base and sought additional user feedback. small changes to the user interface, including the addition of use metrics and color-coded access tags, received immediate attention and positive feedback from key stakeholders. additionally, over the numerous years of development, many projects to improve the repository had stalled for various reasons. by either prioritizing the work necessary to complete the project or accepting the sunkcosts and clearing the backlog for other projects, the technical development team could build momentum, completing projects and clearing mental space for new, exciting endeavors. information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 7 with limited resources on hand, maximizing the return on investment also included an emphasis on securing and keeping internal and external champions. due to the limited outreach conducted early in the system’s existence as well as the mediocre service offerings, many campus users were unaware of the tool, and a few were using the repository in a somewhat limited fashion. in order to build support for the service, it was critical that key users of the repository received targeted support and outreach efforts. a primary example of this was an imaging facility on campus: this unit provided a critical service to campus, yet had difficulty showing the impact of their work as many faculty members did not cite their team in publications. the facility slowly began collecting citations manually, but still struggled to publicly advertise their capabilities and show the fruits of their labor. they solved this problem by loading citation records into the repository, which became the single location where any interested faculty, staff, and students could look to see the full output of the center. while they were using the repository in a somewhat different manner than anticipated, they found the system useful and were actively directing other campus centers and institutes to the repository for similar support. in conversations with them, it became clear that a few modest changes would streamline their workflows and alleviate some cumbersome burdens. with this concentrated outreach and a minimal amount of development, the repository secured a champion that continues to advocate for the service to colleagues across campus. lastly, prioritizing maintenance and paying down technical debt was critical for moving the repository forward. many software dependencies had fallen behind by several major version updates, making it difficult to add new features or consider potential migration paths to future technical solutions. while the amount of technical debt to be paid was substantial, by prioritizing a small amount of maintenance every month, the development team quickly caught up, thereby improving the overall performance of the site and providing the product owners with the flexibility to consider future technical implementations and key features to continue recruiting users. lessons learned and future work moving forward, the product owners are embracing the role of maintainers. in specific reference to repositories, that includes “repairing, caring for and documenting a wide variety of knowledge systems beyond irs to facilitate access and optimize user experience.”17 the work of critically evaluating commitments, establishing clear boundaries, and reaffirming the mission of the repository is useful on a recurring basis, and will need to be continued as the repository ages. maintaining the technical infrastructure as appropriate and conducting user experience testing to improve the service will be critical to ensuring the long-term success of the repository and the information contained therein. beyond the stewardship and small improvements required for maintaining the service, there is the opportunity to reconsider the role of the institutional repository, both at the local level and within the academic community. by prioritizing usefulness over comprehensiveness, the product owners made great strides in making the service accessible to patrons and actually usable. when considering the future of repositories, specifically through a lens of usefulness, it is critical to consider how future work will best serve faculty needs without overburdening librarians. adding pos who are examining how a service will be used and what will promote the mission of the library reframes a repository from being a piece of technology to being a source of interconnections. scholarship usually requires a level of technology different from what most campus it departments can provide: research does not usually just deal in urls, it requires dois information technology and libraries september 2021 product ownership of a legacy institutional repository | narlock and brower 8 and persistent identifiers; files are not just backed up, but are preserved (an active process that requires consideration for how computing will change over the coming decades). not only is a library a place to go to look for data, but it is also a place that can help publish and deposit items, providing valuable services to connect researchers to tools and platforms to facilitate research. this is an area of service that libraries and repositories can provide. in the relationship between libraries and technologies, innovation and maintenance, one clear challenge was the amount of emotional labor necessary to revitalize a service. the pos spent a large portion of time apologizing for previous failures, managing expectations by scaling back previous promises, and grappling with the current technical shortcomings of the service. while this is, at least in part, the role of the pos, the phenomenon of controlling expectations and handling the emotional debt that comes with broken promises and failed technologies is not localized to hesburgh libraries. in libraries especially, this work tends to fall to women, where they are forced to be the middle ground between technology and patron-facing librarians.18 while embracing the term “product owner” has helped to make visible and valuable the labor invested, especially that which might otherwise be overlooked, libraries writ large still need to contend with the gender divide plaguing the seeming dichotomy between innovation and maintenance. 19 in fact, as libraries continue to build new technologies and support innovative research, the role of the product owners in managing legacy technologies will be crucial for success, as will embracing a culture of care and empathy. while beyond the scope of this case study, continued discussions of the gender roles often employed in library technology need to continue, especially as academic libraries embrace scrum methodology, project management, and product ownership. conclusion in this case study, the product owners of a legacy institutional repository described methods for revitalizing a service. for the institutional repository managed by hesburgh libraries, there has been a noticeable increase in usage in the past six months: more deposits, higher access counts, and more support tickets tracked. it appears the efforts of the product owners are showing results. this increased usage is one more piece of evidence that a repository is more than software and more than technology: by allowing the product owners oversight of the mission and ultimate direction of the service, not to mention the freedom to engage with users on behalf of the development team, the system is in a much better position than in previous years. despite these improvements, there is still room for growth as the pos guide the overall mission and development of the institutional repository as both a service and a system. similarly, as more institutions contend with legacy digital technology, using pos and the methods described above may prove beneficial. there is additional work to be done, such as investigating more thoroughly the role of the repository—indeed the concept of the repository—and discussions of gender norms in technology. endnotes 1 this article is based on a presentation by don brower and mikala narlock: “what to do when your repository enters middle age” (online presentation, samvera

automatic subject metadata generation when the pre-1800s long-s character is corrected to a standard < s >. the test environment includes entries from the third edition of the encyclopedia britannica, and the hive automatic subject indexing tool. a comparative study of metadata generated before and after correction of the long-s demonstrated an average of 26.51 percent potentially relevant terms per entry omitted from results if the long-s is not corrected. results confirm that correcting the long-s increases the availability of terms that can be used for creating quality metadata records. a relationship is also demonstrated between shorter entries and an increase in omitted terms when the long-s is not corrected. introduction the creation of subject metadata for individual documents is long known to support standardized resource discovery and analysis by identifying and connecting resources with similar aboutness .1 in order to address the challenges of scale, automatic or semi-automatic indexing is frequently employed for the generation of subject metadata, particularly for academic articles, where the abstract and title can be used as surrogates in place of indexing the full text. when automatically generating subject metadata for historical humanities full texts that do not have an abstract, anachronistic typographical challenges may arise. one key challenge is that presented by the historical “long-s” < ſ >. in order to account for these idiosyncrasies, there is a need to understand the impact that they have upon the automatic subject indexing output. addressing this challenge will help librarians and information professionals to determine whether or not they will need to correct the long-s when automatically generating subject metadata for full-text pre-1800s documents. the problem of the long-s in optical character recognition (ocr) for digital manuscript images has been discussed for decades.2 many scholars have researched methods for correcting the longs through the use of rule-based algorithms or dictionaries.3 while the problem of the long-s is well-known in the digital humanities community, automatic subject metadata generation for a large corpus of pre-1800s documents is rare, as is research about the application and evaluation of existing automatic subject metadata generation tools on 18th-century documents in real-world information environments. the impact of the long-s upon automatic subject metadata generation results for pre-1800s texts has not been extensively explored. the research presented in this paper addresses this need. the paper reports results from basic statistical analysis and visualization using the helping interdisciplinary vocabulary engineering (hive) tool automatic mailto:smg383@drexel.edu information technology and libraries september 2020 evaluating the impact of the long-s | grabus 2 subject indexing results, before and after the correction of the historical long-s in the 3rd edition of the encyclopedia britannica. background work was conducted over the summer and fall of 2019, and the research presented was conducted during winter 2020. the work was motivated by current work on the “developing the data set of nineteenth-century knowledge” project, a national endowment for the humanities collaborative project between temple university’s digital scholarship center and drexel university’s metadata research center. the grant is part of a larger project, temple university’s “19th-century knowledge project,” which is digitizing four historical editions of the encyclopedia britannica.4 the next section of this paper presents background covering the historical encyclopedia britannica data, the automatic subject metadata generation tool used for this project, a brief background of “the long-s problem,” and the distribution of encyclopedia entry lengths in the 3rd edition. the background section will be followed by research objectives and method supporting the analysis. next, the results are presented, demonstrating prevalence of terms omitted from the automatic subject metadata generation results if the long-s is not corrected to a standard small < s > character, as well as the impact of encyclopedia entry length upon these results. the results are followed by a contextual discussion, and a conclusion that highlights key findings and identifies future research. background indexing for the 19th-century knowledge project the 19th-century knowledge project, an neh-funded initiative at temple university, is fully digitizing four historical editions of the encyclopedia britannica (the 3rd, 7th, 9th, and 11th). the long-term goal of the project is to analyze the evolving conceptualization of knowledge across the 19th century.5 the 3rd edition of the encyclopedia britannica (1797) is the earliest edition being digitized for this project. the 3rd edition consists of 18 volumes, with a total of 14,579 pages, and individual entries ranging from four to over 150,000 words. for each individual entry, researchers at temple have created individual tei-xml files from the ocr output. in order to enrich accessibility and analysis across this digital collection, the knowledge project will be adding controlled vocabulary subject headings into the tei headers of each encyclopedia entry xml file. considering the size of this corpus, both in terms of entry length and number of entries, automatic subject metadata generation will be required for the creation of this metadata. the knowledge project will employ controlled vocabularies to replace or complement naturally extracted keywords for this process. using controlled vocabularies adheres to metadata semantic interoperability best practices, ensures representation consistency, and helps to bypass linguistic idiosyncrasies of these 18th and 19th century primary source materials. 6 we selected two versions of the library of congress subject headings (lcsh) as the controlled vocabularies for this project. lcsh was selected due to its relational thesaurus structure, multidisciplinary nature, and continued prevalence in digital collections due to its expressiveness and status as the largest general indexing vocabulary.7 in addition to the headings from the 2018 edition of lcsh, headings from the 1910 lcsh are also implemented in order to provide a more multi-faceted representation, using temporally-relevant terms that may have been removed from the contemporary lcsh. the tool applied for this process is hive, a vocabulary server and automatic indexing application. 8 hive allows the user to upload a digital text or url, select one or more controlled vocabularies, and performs automatic subject indexing through the mapping of naturally extracted keywords to the available controlled vocabulary terms. hive was initially launched as an imls linked open information technology and libraries september 2020 evaluating the impact of the long-s | grabus 3 vocabulary and indexing demonstration project in 2009. since that time, hive has been further developed, with the addition of more controlled vocabularies, user interface options, and the rake keyword extraction algorithm. the rake keyword extraction algorithm has been selected for this project after a comparison of topic relevance precision scores for three keyword extraction algorithms.9 the long-s problem early in our metadata generation efforts, we discovered that the 3rd edition of the encyclopedia britannica employs the historical long-s. originating in early roman cursive script, the long-s was used in typesetting up through the 18th century, both with and without a left crossbar. by the end of the 18th century, the long-s fell out of use with printers.10 as outlined by lexicographers of the 17th and 18th centuries, the rules for using the long-s were frequently vague, complicated, inconsistent over time, and varied according to language (english, french, spanish, or italian). 11 these rules specified where in a word the long-s should be used instead of a short < s >, whether it is capitalized, where it may be used in proximity to apostrophes, hyphens, and the letters < f >, < b >, < h >, and < k >; and whether it is used as part of a compound word or abbreviation.12 this is further complicated by the inclusion of the half-crossbar, which occasionally results in two consequences: (a) the long-s may be interpreted by ocr as an < f >, and < b > and < f > may be interpreted by ocr as a long-s. figure 1 shows an example from the 3rd edition entry on russia, in which the original text specifies “of” (line 1 in top figure), yet the ocr output has interpreted the character as a long-s. the long-s may also occasionally be interpreted by the ocr as a lowercase < l >, such as the “univerlity of dublin” in the 3rd edition entry on robinson (the most rev sir richard). these complications and inconsistencies are challenges when developing python rules for correcting the long-s in an automated way, and even preexisting scripts will need to be adapted for individual use with a particular corpus. figure 1. example from the 3rd edition entry on russia, comparing the original use of a letter < f > in “of” to the ocr output of the same passage, which mistakenly interprets the character as a long-s. information technology and libraries september 2020 evaluating the impact of the long-s | grabus 4 despite the transition away from the long-s towards the end of the 18th century, the 3rd edition of the encyclopedia britannica (published in 1797) implements the long-s throughout, with approximately 100,594 instances of the long-s in the ocr output. when performing metadata generation with the hive tool on the ocr output for an entry, the long-s is most often interpreted by the automatic metadata generation tool as an < f >, which can result in (a) inaccurate keyword extraction (e.g., russians→ ruffians), and (b) when mapping extracted keywords to controlled vocabulary terms, essential topics could be unidentifiable, and hive will subsequently omit them from the results because they cannot be mapped to controlled vocabulary terms. figure 2 provides a truncated view of long-s words in the 3rd edition entry on rum, which are subsequently removed from the pool of automatically extracted keywords when performing the automatic subject indexing sequence in hive. using keyword extraction algorithms that are largely dependent upon term frequencies, automatic subject indexing for an entry on rum may be substantially hindered when meaningful and frequently occurring words such as sugar, and yeast are removed. figure 2. examples of the long-s in the 3rd edition encyclopedia britannica entry on rum. using this example entry, the automatic subject indexing results were compared using python, to determine which terms only appear when the long-s has been corrected to the standard < s >. the comparison showed that 16 total terms no longer appeared in the results when the long-s was not corrected to a standard < s >: ten terms using the 2018 lcsh, and six terms using the 1910 lcsh. these omitted results included the terms sugar and yeast. the next section will discuss the encyclopedia entry word count for this corpus, and the possible impact that this may have upon automatic subject indexing between corrected and uncorrected long-s instances. encyclopedia entry lengths consistent with other encyclopedia britannica editions in the 18th and 19th centuries, the encyclopedia entries in the 3rd edition vary substantially in length. a convenience sample of 3,849 3rd edition entries ranging in length from 2 to 202,848 words demonstrated an arithmetic mean of information technology and libraries september 2020 evaluating the impact of the long-s | grabus 5 826.60, and a median word count of 71. as shown in figure 3, this indicates a significant skew towards shorter entry lengths. for the vast majority of encyclopedia entries in this corpus, a low total word count may impact the degree of long-s impact for automatic subject indexing results, given the importance of term availability and frequency for keyword extraction algorithms. figure 3. scatterplot of word count for a convenience sample of 3,849 3rd edition encyclopedia britannica entries. large-scale metadata generation requires time, labor, and resources, and it becomes more costly when accounting for the complications of correcting the long-s for a particular corpus. library and information professionals working with digital humanities resources will need to understand the impact of correcting or not corrected the long-s in the corpus before designating resources and developing a protocol for generating the automatic or semi-automatic metadata for full-text resources. this includes understanding whether or not the length of each individual document will affect the degree of long-s impact upon the results. this challenge, and issues reviewed above, are in the research presented below. objectives the overriding goal of this work is to determine the prevalence of omitted terms in automatic subject indexing results when the long-s is not corrected in the 3rd edition entries of the encyclopedia britannica. research questions: 1. what is the average number of terms that are omitted from automatic subject indexing results when the long-s is not corrected to a standard < s >? 2. how does the encyclopedia entry length affect the number of terms that are omitted when the long-s is not corrected to a standard < s >? this analysis will approach these goals by performing a comparative analysis of automatic subject indexing results to determine the number of terms that are omitted from the results when the long-s is not corrected to a standard letter < s >. basic descriptive statistics are generated to determine central tendency. the quantity of terms omitted are then compared with encyclopedia information technology and libraries september 2020 evaluating the impact of the long-s | grabus 6 entry word counts. these objectives were shaped by collaboration between drexel university’s metadata research center and temple university’s digital scholarship center. the next section of this paper will report on methods and steps taken to address these objectives. methods we approached this research by performing a comparative analysis of subject metadata generated both before and after the correction of the historical long-s in the 3rd edition of the encyclopedia britannica. the hive tool was used to automatically generate the subject metadata. descriptive statistics were applied, and visualizations produced from the results were also examined to identify trends. figure 4. the 30 encyclopedia britannica 3rd edition encyclopedia britannica entries randomly selected for this study, sorted in ascending order by their word counts. the protocol for performing this research involved the following steps: 1. compile a sample for testing: 1.1. a random sample of 30 encyclopedia entries was identified from a convenience sample of entries that comprise the letter s volumes of the 3rd edition. the entries range, in length, from 6 to 6,114 words. the median word count for entries in this sample is 99 words. 1.2. the sample of terms selected for this study and their respective word counts are visualized in figure 4. 1.3. for each entry, the long-s terms in the original xml file were extracted to a list. 2. perform automatic subject indexing sequence upon entries to generate lists of terms: 2.1. using the 2018 and 1910 versions of the lcsh. 2.2. with fixed maximum subject heading results set to 40: 20 maximum terms returned with the 2018 lcsh, and 20 maximum terms returned with the 1910 lcsh. 2.3. before long-s correction and after long-s correction, using the oxygen xml editor tei to txt transformation. information technology and libraries september 2020 evaluating the impact of the long-s | grabus 7 3. perform outer join on python data frames, between terms generated when the long-s has been corrected vs. terms generated when the long-s has not been corrected. the resulting left outer join list displays terms that are omitted from the automatic indexing results if the long-s is not corrected to a standard small < s >. the quantity of terms omitted are recorded for comparison. 4. analysis: descriptive statistics were generated to determine central tendency for the number and percentage of words omitted when the long-s is not corrected. the quantity of terms omitted are also visualized in a continuous scatterplot with the corresponding word counts, to demonstrate that the quantity of terms omitted when the long-s is not corrected seems to relate to the length of the document being automatically classified. results the results report the prevalence of omitted terms when the long-s is not corrected to a standard < s >, as well as a visualization of the number of terms omitted as they relate to the encyclopedia entry length. for each of the 30 sample entries automatically indexed with hive, a fixed maximum number of 40 entries were returned: a maximum of 20 terms using the 2018 lcsh, and a maximum of 20 terms using the 1910 lcsh. as seen in table 1, central tendency is measured using the arithmetic mean and median, along with the standard deviation and range. the average number of terms omitted from an entry’s results is 6.73, and the average percentage of terms omitted from an entry’s results is 26.51 percent, with the 2018 and 1910 editions of lcsh performing at similar rates. the full results are displayed in appendix a. table 1. measures of centrality, standard deviation, range, and percentage for quantity of terms omitted when the long-s is not corrected to a standard < s >, rounded to the hundredth. for each entry, a maximum of 40 terms were returned: 20 using 2018 lcsh and 20 using 1910 lcsh. the total results returned varies according to the entry length. these totals are reported in appendix b. (n= 30 entries.) for each entry in the sample, the results in appendix a display the total words omitted when the long-s is not corrected, the number of 2018 lcsh terms omitted, the number of 1910 lcsh terms omitted, and the encyclopedia entry word count. figure 5 visualizes the total number of terms omitted for each entry when the long-s is not corrected, demonstrating an increase in terms omitted for entries with lower word counts. these results are broken down by vocabulary used in figure 6, demonstrating that both vocabularies used to generate these results indicate a significant increase in omitted terms for shorter entries. column1 both vocabularies 2018 lcsh 1910 lcsh average, terms omitted 6.73 3.67 3.07 median, terms omitted 5 3 2 standard deviation 6.53 3.84 3.17 range,

terms omitted if the long-s is not corrected to a standard < s > prior to automatic subject indexing using hive, as well as a visualization to represent the relationship between encyclopedia entry word count and number of terms omitted. although researchers have identified challenges with the long-s and have focused a great deal on the technologies and methods used to correct it, there is still limited work on looking at the results of not correcting the long-s character when performing an automatic subject indexing sequence. this research demonstrated an average of 6.73 potentially relevant terms omitted from automatic indexing results when the long-s is not corrected, accounting for an average of 26.51 percent of the total results, with an approximately equal distribution of omitted terms across the two controlled vocabulary versions used. when the quantity of terms omitted is visualized using a continuous scatterplot, the results also demonstrated a significant increase in omitted terms for shorter entries, with longer entries less affected. these results reflect the impact of term frequency and total word count in keyword extraction and automatic subject indexing, with longer documents having a greater pool of total terms from which to identify key terms. considering the complexities and similarities of the typographical characters in the original manuscript, the ocr output process for this corpus occasionally mistakes the letters < s >, < f >, < r >, and < l >. as a result, an occasional long-s word in this study did not originally contain an < s > (e.g., sor instead of for). correction of these long-s ocr errors requires the development of a dictionary-based script. an additional complication of this research is that the corrected ocr output for the encyclopedia entries still contains a few errors not related to the long-s, which will prevent the mapping of the term to any controlled vocabulary term (e.g., in the entry on sepulchre, the ocr output for the term palestine was palestinc). these results are specific to this particular corpus of 3rd edition encyclopedia britannica entries, but it is very likely that testing another set of pre-1800s documents containing the long-s would also illustrate that for best results with any algorithm or tool, the long-s needs to be corrected. the results are also specific to the two versions of the lcsh used, both the 1910 lcsh and the 2018 lcsh, which are available in the hive tool. the 1910 version is key for the time period being studied, and the 2018, more contemporary to today, has supported additional analysis on the impact of the long-s. both of these vocabularies are important to the larger 19th-century knowledge project. it should be noted that while the lcsh is updated weekly, we were limited to what is available via the hive tool, and any discrepancies that may be found with the 2020 lcsh will very likely have a minimal effect upon metadata generation results. it should be noted that the 2020 lcsh will be incorporated into hive soon and can be explored in future research. conclusion and next steps the objective of this research was to determine the impact of correcting the long-s in pre-1800s documents when performing an automatic metadata generation sequence using keyword extraction and controlled vocabulary mapping. this was accomplished by performing an automatic subject indexing sequence using the hive tool, followed by a basic statistical analysis to determine the quantity of terms omitted from the results when the long-s is not corrected to a standard < s >. the number of omitted terms was also compared with the encyclopedia entry word count and visualized to demonstrate a significant increase in omitted terms for shorter information technology and libraries september 2020 evaluating the impact of the long-s | grabus 10 encyclopedia entries. the study was conclusive in confirming that the correction of the long-s is a critical part of our workflow. the significance of this research is that it demonstrates the necessity of correcting the long-s prior to performing an automatic subject indexing on historical documents. beyond the correction of the long-s, the larger next steps for this project are to continue to explore automatic metadata generation for this corpus. these next steps include the comparison of results using contemporary vs. historical vocabularies and streamlining a protocol for bulk classification procedures and integration of terms into the tei-xml headers. the research presented here can inform other digital humanities and even science-oriented projects, where researchers may not be aware of the impact of the long-s on automatic metadata generation not only for subjects, but also named entities, particularly when automatic approaches with controlled vocabularies are desired. acknowledgements the author thanks dr. jane greenberg and dr. peter logan for their guidance. the author acknowledges

yongming wang (wangyo@tcnj.edu) is systems librarian, the college of new jersey. © 2022. abstract the use of artificial intelligence and machine learning has rapidly become a standard technology across all industries and businesses for gaining insight and predicting the future. in recent years, the library community has begun looking at ways to improve library services by applying ai and machine learning techniques to library data. chat reference in libraries generates a large amount of data in the form of transcripts. this study uses machine learning and natural language processing methods to analyze one academic library’s chat transcripts over a period of eight years. the built machine learning model tries to classify chat questions into a category of reference or nonreference questions. the purpose is to predict the category of future questions by the model with the hope that incoming questions can be channeled to appropriate library departments or staff. introduction since the beginning of this century, artificial intelligence (ai) and machine learning (ml) have been used in almost all industries and businesses to gain knowledge and insights and predict the future. the large amount of data available has helped to accelerate the application of ai and ml in stunning speed. to follow this technology trend, the library community has begun looking at ways to improve library services by applying ai and ml techniques to library data. stanford university library is one of the pioneers in the research and application of ml and ai in the library. the mission of its library ai initiatives states: “the library ai initiative is a program to identify, design, and enact applications of artificial intelligence that will help us make our rich collections more easily discoverable, accessible, and analyzable.” 1 in 2019, stanford university library hosted the second international conference on ai for libraries, archives, and museums, titled fantastic future.2 many academic libraries have implemented chat reference services as a way to support student learning and academic research on campus. chat reference serves as an important channel to connect the library’s resources and services to the campus community.3 over the years, libraries have accumulated a large amount of data in the form of chat transcripts. analyzing the content of transcripts can help the library understand users’ information needs, deploy library human resources more efficiently, and improve the quality of the chat reference service. the college of new jersey is a midsize academic library that serves a campus with 7,000 college students, most of them undergraduates. the library began to use springshare’s libchat in 2014. the chat service is freely accessible online from the library’s website, and anyone can initiate a chat by asking an initial question through the chat box. approximately 8,000 chat transactions have been accumulated over the past eight years. information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 2 this study aims to use machine learning and natural language processing (nlp) techniques to build a classification model to categorize all available questions into two categories: reference and nonreference. by doing so, we hope that the model can automatically classify future chat questions received into either the reference question category or the nonreference question category, and channel the question to the appropriate library department or staff. literature review traditionally, the analysis of chat transcripts has used qualitative or simple quantitative methods (e.g., chat frequency, duration). to better understand chat service quality and patrons’ information needs, librarians must manually review and read through chat transcripts, which requires a lot of time and effort.4 in recent years, however, the library field has started to witness the application of ai and ml techniques to analyze library data, including chat transcripts, in order to quickly and efficiently gain more insight into user information needs and information seeking patterns. megan ozeran and piper martin used topic modeling, a ml method, to analyze library chat reference conversations. the purpose of their project was to identify the most popular topics asked by library patrons in order to improve the chat reference service and to train the library staff.5 the brigham young university library implemented a machine learning–based tool to perform various text analysis on transcripts of chat reference to gauge patron satisfaction levels and to classify patrons’ questions into several categories.6 jeremy walker and jason coleman used ml and nlp techniques to build models that predict the relative difficulty of incoming chat reference questions. they tested their large sample size of chat transcripts on hundreds of models. their aim was to help library professionals and management improve chat reference services in the library.7another ml topic modeling project of was carried out by hyunseung koh and mark fienup. their study applied plsa (probabilistic latent semantic analysis) to library chat data over a period of four years, resulting in more accurate and interpretable topics and subjects compared with results by human qualitative evaluation.8 another interesting ml project on chat reference data was conducted by ellie kohler. this project used a machine learning model to analyze chat transcripts for sentiment and topic extraction. 9 in addition to library chat data, ml has been also used to analyze other library data, including library digital collections and library tweet data. jeremiah flannery applied nlp summarization techniques on a special library digital collection of catholic pamphlets. this project tried to automatically generate a summary for each digitized pamphlet by using nlp’s bert extractive technique and gensim python package.10 sultan m. al-daihani and alan abrahams conducted a text mining analysis of academic libraries’ tweets. they used a tool called pamtat developed by the pamplin college of business at virginia polytechnic institute and state university. pamplin is a microsoft excel–based interface to the nlp nltk package written in python. the purpose of their analysis was to try to identify the most common topics or subject keywords of the tweets by 10 large academic libraries. in addition, they also ran harvard general inquirer for semantic and sentiment analysis of the tweets.11 information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 3 other applications of ml techniques in the academic library include analyzing library operations such as acquisition. in 2019, kevin w. walker and zhehan jiang from the univers ity of alabama used a machine learning method called adaptive boosting (adaboost) to predict demand -driven acquisition (dda).12 carlos g. figuerola, franciso javier carcia marco, and maria pinto used the topic modeling technique, specifically the latent dirichlet allocation, to identify the main topics and categories of the 92,705 publications in the domain of library and information science from 1978 to 2014.13 pair (projects in artificial intelligence registry) is a repository and online global directory of ai projects in higher education. it is maintained by the university of oklahoma libraries. the aim of pair is to foster cross-institutional collaboration and to support grant activity in the field of artificial intelligence and machine learning in higher education.14 public libraries have started to seriously look at the application and impact of ai in the library. frisco public library in texas has developed a series of applications and programs to help train library staff in ai. they also developed artificial intelligence maker kits, including google aiy voice kit, for circulation. they even provide introductory python lessons to the public.15 background of nlp and ml natural language processing is a multidiscipline field that involves linguistics, computer science, and machine learning. by using computer algorithms, nlp tries to build a machine learning model that is applied to large amounts of data in order to make predictions or decisions. the data in nlp is natural language data, that is, data in plain and unstructured textual form in any language. there are many types of applications of nlp and ml in business or people’s daily lives. especially with the popularity of internet, there is a tremendous increase in and accumulation of textual data, such as social media networks and customer online chat services. major applications of nlp include sentiment analysis on social media data, topic modeling in digital humanities, text classification, speech recognition, search box auto correct, and auto completion, etc. the use cases are countless. in general, there are two types of ml: supervised learning vs. unsupervised learning. in supervised learning, the dataset fed to the model is labelled in advance to classify data or predict outcomes accurately whereas unsupervised learning is a type of algorithm that learns patterns from unlabeled or untagged data. no matter which type, all ml and nlp techniques involve a series of general steps in any project, also called the ml/nlp pipeline. 1. data collection, which involves obtaining the raw textual data and usually means downloading data from some remote server or service. 2. data preprocessing, which is necessary for any project, large or small, because the raw textual data is unstructured data and is not ready to be fed to the model for computing processes. data preprocessing usually includes removing punctuations, changing all letters to lowercase, tokenization, removing stop words, and stemming or lemmatization. 3. feature engineering, which is optional but often very useful. 4. text vectorization, which is the final step before feeding the data to the model. the purpose is to transform the text into some kind of value in numbers. information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 4 5. model building, evaluation, and optimization, which involves multiple cycles until the optimal or desired results are achieved. 6. implementation, which is the final step in implementing the model to the real world. methodology for this ml/nlp project, the raw data came from the chat transcripts repository downloaded from springshare’s server. from 2014 to 2021, a total of 8,000 chat reference transactions were logged. these transactions formed the raw dataset for model building and testing with this project. because of the nature of the data, i.e., textual data, python was chosen for this project. and the two major python packages used in the project are nltk and scikit-learn. nltk (natural language toolkit) is a suite of libraries and programs for natural language processing for english language. nltk supports classification, tokenization, and stemming, tagging, parsing, and semantic reasoning functionalities. scikit-learn is a python module built on numpy, scipy, and matplotlib. featuring various classification, regression, and clustering algorithms, including support-vector machines, random forest, gradient boosting, k-means and dbscan, scikit-learn is a simple and efficient tool for predictive data analysis. scikit-learn is one of the most popular python modules for any ml project. data collection data collection includes both data gathering and data preparation. data gathering is the process of downloading the 8,000 initial questions into an excel file. data preparation deals with the initial data clean up, such as removing the blank rows. the most important task of data preparation is data labelling. because this is a supervised-learning ml project, all questions must be labeled as either reference question (label=yes) or nonreference question (label=no) by hand. then, all labeled questions (dataset) are fed to the ml model for either training purposes or testing purposes. see table 1 for an example of data after the preparation step. table 1. sample questions with yes or no labels question sequential number label question 3979 yes working on an alumni reunion presentation. i need to know … 3980 yes would a book with this

… information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 5 data preprocessing data preprocessing is the first programming step in the pipeline of this ml/nlp project. data preprocessing transforms the raw data into a more digestible form so that the ml model can perform better and achieve the desired results. one of the purposes of data preprocessing is to remove insignificant and nonmeaningful words such as “a,” “the,” “and,” etc., as well as punctuation, from the textual data. removing nonmeaningful and stop words from the corpus allows for a better result in the ml model, allowing it to deal only with significant and meaningful words. it is also necessary to apply lowercase formatting to all letters. while we as humans know that lowercase and uppercase words have the same meaning, the computer will treat them as having different meanings. for example, “cat” and “cat” are two different words to the computer. tokenization involves splitting the sentences into a list of individual words by removing spaces between words. the last step of data preprocessing is stemming or lemmatizing, which is to find the semantic meaning of a group of related words. in other words, this process explicitly correlates words with similar meanings. for instance, run, running, runner will become “run” ; library and libraries will become “librari”; goose and geese will become “goose.” feature engineering involves creating a new feature, or transforming the current feature. the purpose of feature engineering is to help the model make better predictions. this step is optional but often very helpful if done right. in this project, a new feature called “question length” was created. “question length” was based on the assumption that the average length of reference questions is longer than the average length of nonreference questions. if such is the case, the ml model will benefit by using this new feature to make better decisions. figure 1 is a histogram of question length distribution. the distribution of reference questions is represented in blue; nonreference questions are represented in yellow. figure 2 shows a sample result list following completion of data preprocessing and feature engineering. from left to right, it lists the result after each step. the question length feature (question_len column) must follow the original question because this step is based on the original question before any other steps. the question_lemma column is the result after all preprocessing steps. information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 6 figure 1. histogram of question length distribution. figure 2. results from data preprocessing and feature engineering. information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 7 text vectorization the purpose of text vectorization is to transform the text data into numeric data so that the ml algorithms and python can understand and use that data to build a model. the basic idea is to build an n-dimensional vector of numerical features that present some object. the three most popular text vectorizations are count vectorization, n-grams vectorization, and tf-idf vectorization. tf-idf stands for term frequency–inverse document frequency. because it is weighted, it is more accurate. figure 3 shows the result of tf-idf vectorization. figure 3. result of tf-idf vectorization. model building, testing, and evaluation the first step of model building is to divide the dataset into two sets, one for a training model and one for model testing. normally we use 80% of the data for training and 20% for testing. after feeding the training data to the model, we feed the testing data as new data to the model to predict the yes or no label based on the pattern that the model builds through the training data. testing data were initially labeled by humans and are 100 percent accurate. by comparing the labels predicted by the model with the labels in the training data, we would know how the model performs, and make changes, if necessary, to the model parameters. scikit-learn contains several ml models. this project used two popular models: random forest and gradient boosting. the random forest model builds many decision trees and computes them at the same time. then the final decision is made by majority vote. because it computes at the same time, it is more efficient and fast. the gradient boosting model builds one tree at a time. each new tree helps correct errors made by previously trained trees, and then the model is boosted (optimization) by reward or penalty. in theory, gradient boosting should yield better results than random forest. nevertheless, it is slower and consumes more resources. the confusion matrix was used to evaluate the performance of the two models. there are three parameters in the confusion matrix. they are accuracy, precision, and recall. accuracy equals true positive plus true negative and then divided by the total. precision equals true positive divided by information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 8 true positive plus false positive. recall equals true positive divided by true positive plus false negative. usually there is a tradeoff between precision and recall. recall shows the number of false negatives or the percentage of false negatives of the total, and precision shows the number of false positives. false negative means that the model predicts the reference question as a nonreference question. false positive means that the model predicts the nonreference question as a reference question. which is more important for the model to catch, false positive or false negative? the answer depends on the actual situation. in our case, false negative is more serious than false positive because we did not want the real reference questions to be predicted as nonreference questions. however, it was acceptable if the nonreference questions were predicted as reference questions. therefore, we wanted the least amount of false negatives, which meant the largest recall value possible. results and analysis table 2 lists the result from both models. table 2. results of random forest model and gradient boosting model precision recall accuracy fit time predict time random forest model 0.914 0.964 0.912 2.489 s 0.15 s gradient boosting model 0.904 0.948 0.894 97.786 s 0.064 s in general, any parameter values above 0.9 (90%) are very good. looking at and comparing those results, we can see that both models performed well. nevertheless, the random forest model had better results than that of the gradient boosting model in all three parameters. in addition, the fit time of the random forest model was much shorter than that of the gradient boosting model. even though the predict time of the random forest model is slightly longer than that of the gradient boosting model, it is relatively insignificant. therefore, the random forest model was chosen for the final model for this project. conclusion and future work in this pilot study, we used the classification modeling of nlp and ml techniques to divide patrons’ chat questions into two categories: reference questions and nonreference questions. the purpose of the model is to predict the category of future questions received through chat so that library staff and professionals can provide faster, more efficient reference services. two machine learning models were tested: random forest and gradient boost. after comparing results from each model, it was concluded that the random forest model showed better results. what is the next step after the model is built? a potential use of this model is to implement it as a plugin or feature enhancement for the online chat application. the model can function as the filter to direct incoming questions to either reference librarians if the question is predicted as a reference question by the model, or to library staff or graduate student assistants if the question is predicted by the model as a nonreference question. this will be especially useful for libraries that have busy online chat service transactions. information technology and libraries september 2022 using machine learning and natural language processing to analyze library chat reference transcripts wang 9 further work can be done to make the model be multicategory. for example, a multicategory model can go beyond two categories and include categories for information seeking, citation help, printing help, noise complaints, interlibrary loan questions, spams, etc. thus, the model can send the question to the relevant department or library personnel accordingly. endnotes 1 “stanford university library ai initiative,” stanford university library,

william g. squires library conducted a usability study on their libguides to identify student design preferences. the results of the study support previous research concerning best practices for libguide creation. this paper offers insight into how librarian-centric design hinders student success and provides suggestions for how to best develop a student-centric template design that offers consistency and increased user proficiency across all guides. introduction librarians are gatekeepers of information; ensuring that others can identify, locate, and access the information they need is at the heart of librarianship. one way that librarians assist patrons in their search for information is through the creation of libguides, a product offered through springshare. springshare’s libguides allows librarians to easily create web content, even those librarians who cannot boast advanced technological expertise. 1 springshare handles the technical side of web creation, making it possible for librarians to focus on creating and curating content. however, without proper oversight by librarians and established institutional procedures for creation and maintenance, libguides can become problematic. research and experience have shown that while libguides are a powerful tool in the librarian’s toolbelt, inadvertent mismanagement leads to a variety of problems. this article seeks to better define these problems and, through a reiterative usability study conducted on lee university library’s libguides, will identify best practices to assist libraries in overcoming these obstacles. the usability study went through multiple adaptations, taking the knowledge gained from the previous analysis and applying that learning to the next iteration. why a usability study? the william g. squires library has five faculty librarians, seven staff members, and serves approximately 4,000 students. libguides serve as the library’s website. there is one page on the lee university website that states the library’s mission statement and provides the library’s contact information. however, to access the library’s “website,” users must click a continue button, which links to the library’s landing page in libguides. once on the library’s landing page in libguides, users can access all the library’s resources, including a link to the library catalog, links to library databases, and links to other guides that provide useful information and research aids to patrons. while the usage statistics provided by libguides show which guides are most often mailto:julieburchfield@leeuniversity.edu mailto:mpossi00@leeu.edu information technology and libraries december 2023 taming the beast 2 burchfield and possinger visited, they do not tell the story of how users interact with the site. to see how students are interacting with the libguides, the library decided to perform a usability study. the usability study provided the insight needed to establish design guidelines for reformatting existing guides and creating new ones. the librarian responsible for the maintenance and oversight of the library’s guides felt that it was critical to have user feedback before establishing a library guide template. previously, each librarian had the autonomy to build their guides in whichever way they saw fit. the only guidelines previously put in place were that guides use a common banner for each page and common colors for boxes, backgrounds, tabs, and text. each creator took advantage of this autonomy to produce guides that expressed their personalities and personal preferences. some guides were wordy, providing lots of information in terms of explanation and instruction. other guides were minimalistic, simply providing links to searches about a certain topic with little to no explanation or instruction. the terminology varied from guide to guide, and some guides used side navigation while others used top navigation. such distributed authorship results in a lack of similarity within the created guides which can lead to confusion amongst users, rendering guides less effective and less efficient.2 conducting a usability study provided the librarians with design ideas that went beyond personal taste and were based instead on demonstrated user needs and preferences. literature review background and purpose the purpose of a library libguide is to provide students with point-of-need research support.3 libguides allow librarians to offer research assistance outside the traditional one-shot instruction session. while libguides are widely used in the academic library setting, questions still arise concerning their educational effectiveness among students.4 much of the research suggests that librarians who are subject specialists in their areas of expertise may not have the needed skills to translate their knowledge into student-centric designs.5 each librarian creates a guide that is, by their own account, user-friendly and informational all the while failing to consider the design preferences and research processes of the student. this pattern of libguide creation produces library-centric creations as opposed to student-centric designs.6 when libguides are librariancentric, fitting the organizational mental model of the librarian instead of the student, students often turn to websites that are familiar and easier to use.7 to create student-centric libguides, it is important to attempt to identify and consider the information needs and study patterns of students. focusing on the research behaviors of the student allows for a guide design that matches the students’ pedagogical needs. 8 past research emphasized the need to perform “qualitative and task-based user testing” to better understand how students interact with the libguides and what their design preferences might be. 9 the purpose of the usability study is to provide the libguide creator an opportunity to understand exactly how students are maneuvering through the site and to attempt to identify problem areas for users.10 considering the goal of the usability study, the research team placed extra emphasis on examining how students navigate both the library’s libguide landing page as well as the different styles of libguide research starters. information technology and libraries december 2023 taming the beast 3 burchfield and possinger common problems with libguides as identified by students interestingly, many student-centered usability studies fail to identify a preferred layout design. participants from multiple usability studies provided mixed reviews when asked to identify a preferred layout.11 however, the studies excel in identifying problem areas that need to be addressed.12 guide inconsistency complicates navigation for users.13 studies have shown that students are confused by the use of library lingo on guides.14 many libguides contain duplicated content, creating a bulky collection of library guides that are not necessarily unique but neither would they be considered uniform.15 students disengage with guides that contain overwhelming amounts of information or that are not clear in their purpose.16 statistical information shows that students do not scroll to the bottom of most pages, meaning that information located at the bottom of a page is often overlooked by users.17 the reliability and authority of the library’s libguides come under scrutiny when students find broken links and/or out-of-date content.18 support for templates one proposed solution to many of the commonly identified problems in libguides is to institute a template design. a template design discourages an overabundance of “words, links, images, tabs, and other visual forms that contribute to user confusion.”19 templates ensure the use of standardized language for labeling guide content and tabs, decreasing frustration amongst users. 20 requiring creators to utilize a specific layout ensures that users will become familiar with how to navigate the libguides, decreasing the need for the user to learn how to traverse each new page before making use of the content located therein.21 establishing template guidelines for a library’s libguides helps create uniformity across all guides and has a two-fold benefit. for students, the student-centric design of the template contributes “to its cognitive effectiveness and efficiency,” increasing student understanding and generating a greater likelihood of student success.22 for librarians, the common template allows the librarian to focus on content instead of design.23 librarians want students to be able to focus more purposefully on their research task instead of being further challenged by the navigation of the libguide.24 this ideology is in alignment with cognitive load theory, which asserts that libguides should be as concise and intuitive as possible and, as a result, students will not have to exert extra effort in understanding how to navigate the guide itself but can, instead, focus their energies on analyzing and understanding the information provided on and through the guide.25 methodology participants the only criterion for an individual to participate in the library’s usability study was that the person be a current student at lee university and that they be willing to dedicate up to one hour of their time. participants for the study were solicited via a campus-wide advertisement campaign. student participation was incentivized by including entrance into a drawing for a $10 amazon gift card. in the fall 2022 semester, 10 students participated in the usability study. in the spring semester, the office of undergraduate research & scholarship (ours) partnered with the usability study implementation team—the librarian responsible for the oversight of the library’s libguides and her student assistant—to offer every student who completed the study a $10 amazon gift card. ours was also able to target student groups via email. this increased incentivization motivated more individuals to participate, with a total of 19 students participating in the spring semester. information technology and libraries december 2023 taming the beast 4 burchfield and possinger to schedule appointments, students were directed to an online website called calendly via a hyperlink or by scanning a qr code. calendly allowed the research assistant to schedule specific times to run the hour-long usability study. this simple website was very user-friendly, and participants could easily select an appointment slot. personnel and technology the usability study was conducted by the librarian who is responsible for the oversight and maintenance of the library’s libguides. the librarian also had one student assistant who joined the usability study implementation team through funding provided by the university’s work-study research assistant program (wrap). purchase of the screen recorder and video editor software camtasia and the screen capturing software snagit was funded through ours, and both programs were installed on a computer located in the library’s receiving room. this receiving room was separate from the main area of the library, so it provided a quiet and relatively undisturbed area within which to conduct the usability study. large video files were shared between the usability study implementation team via microsoft teams. the video files consisted of the audio and screen capture of each session. before beginning the usability study, those directing the research participated in the udemy course usability testing boot camp to learn more about how to properly execute a usability test. this training emphasized the typicality of using small numbers of participants in the usability test, generally about five participants within each iteration.26 this style was adopted for the library’s usability study, especially since the librarian conducting the usability testing had access to make immediate updates and changes to the library’s libguides. the librarians met prior to the start of the study to determine the “red routes,” or the most common reasons students would visit and utilize the library’s landing page based on questions frequently asked by students at the library’s circulation and reference desks.27 these red routes included reserving a study room, locating a print book, locating peer-reviewed journal articles, and identifying an applicable database for use in individual research. these key tasks were then developed into scenarios to be used in the upcoming usability test (to read the original usability tasks, see appendix a). throughout the semester tasks were modified or dropped from the usability study. for example, if students were struggling to understand a task, the task was altered for clarity. if most participants successfully completed certain tasks with ease, those questions were eliminated from the study. all tasks and their evolutions were recorded on a microsoft excel spreadsheet. paper prototyping and advanced scribbling in addition to providing participants with tasks to be completed online, paper prototyping and advanced scribbling were used to garner student feedback about layout, design, and content. paper prototyping refers to creating paper examples of current or potential online designs .28 advanced scribbling allows participants to provide written feedback on a paper copy of the digital design, including highlighting and annotation.29 this new method was not implemented until the spring semester. students were given a paper copy of the library’s landing page along with three different colored highlighters, each corresponding to a category: important/useful, confusing, and unnecessary. participants were asked to critique the landing page. additionally, they were asked to provide their thoughts and comments about the landing page on a separate piece of paper. to information technology and libraries december 2023 taming the beast 5 burchfield and possinger ensure the usability study did not last longer than an hour, a time limit was given for the paper prototyping and advanced scribbling section of the study. time management to allow time to evaluate and analyze the feedback received during the usability studies, the research team decided to conduct usability studies every other week. therefore, the alternate weeks consisted of debriefings of past usability studies and preparation and alterations for the following week’s studies. results participants twenty-nine students participated in the usability study, with 10 participating in the fall semester and an additional 19 taking part in the spring semester. freshmen to graduate students (see fig. 1) from a variety of majors (see fig. 2) were represented in the study. some students self-reported having only introductory experience researching while others considered themselves advanced researchers (see fig. 3). figure 1. usability study participants by classification. information technology and libraries december 2023 taming the beast 6 burchfield and possinger figure 2. usability study participants by discipline. figure 3. usability study participants’ self-assessed level of research expertise. standardized/common language the fall usability study quickly revealed that the lack of standardized, common language on the libguides was an obstacle to student success. problem areas included the language used to describe the research starters (libguides created to support the individual research needs of a information technology and libraries december 2023 taming the beast 7 burchfield and possinger specific course or discipline), the library search box, and the resources available in the database a–z list. in library instruction sessions, students are introduced to their course’s research starter, which is the terminology that librarians consistently use to refer to these libguide research aids. students found it challenging to locate the class research starters from the library’s landing page because they were placed under a tab labeled research help. students did not make the connection between research help and class research starters. as a result, the librarians decided to be very forthcoming and label the tab find a research starter. the tab was also moved up from the fifth tab to the third tab in the menu. after making this change, students were very successful in locating the research starters with all spring participants completing this portion of the task. another issue discovered during the fall semester included the language used on the ebsco discovery service (eds) search box located on the library’s landing page. it was not clear to student participants what purpose this search box served as most students were unfamiliar with the search capabilities of the eds. as a result, the librarians created a more simplistic description for the main search bar. originally titled search the library’s ebsco discovery service, the language was changed to “find articles, books, and other resources.” also, within the search box, text was added to instruct students to “type your search term here” (see fig. 4). figure 4. ebsco discovery service search box revision. additionally, the database a–z list landing page was refined. the fall semester demonstrated that students did not understand what the vendor/provider tool referred to and students used the search bar incorrectly, often searching for their search term rather than a specific database name (see fig. 5). therefore, both items were removed. to help bring more clarity, a collection of popular databases was added to the a–z landing page (see fig. 6). also, each list of subject-specific databases was tagged with top picks for the discipline of study. after these changes were implemented later in the spring semester, nine out of 10 students were able to successfully complete the task of finding a specific database. information technology and libraries december 2023 taming the beast 8 burchfield and possinger figure 5. screenshot of a–z list prior to revisions. figure 6. screenshot of a–z list after revisions. citation help after the fall semester, the librarians and research team recognized that finding citation help was another red route that should be highlighted in the upcoming spring semester usability test. a new task was added that asked students to locate citation help from the library landing page. four spring usability study participants attempted the task, and all four students failed to complete the task, making it apparent that a change needed to be made. the citation tools were housed in their information technology and libraries december 2023 taming the beast 9 burchfield and possinger own topic research starter but there was no direct link to this resource from the library landing page. as a result, a tab named find citation help was added to the library landing page, directly after the find a research starter tab (see fig. 7). after this addition, the success rate of students for this task was 13 of 15. figure 7. updated tabs on the library landing page. paper prototyping and advanced scribbling one important enhancement the research team made to the spring semester usability study was adding the paper prototyping and advanced scribbling portion. this allowed the research team to review specific comments that students had about the library’s landing page. the firsthand student feedback allowed the team to better understand which aspects of the library’s libguides were important, confusing, or unnecessary. sections of the landing page that students found important included the library hours (17/19 students), library contact information (14/19 students), find a book (14/19 students), reserve a study room (14/19 students), find a database (13/19 students), library search box (12/19 students), and chat with a librarian (12/19 students). nine student respondents marked the library description and the library mission statement as either unnecessary or confusing, which could support the idea that students do not naturally gravitate towards long passages of text. determining student preference the usability study quickly revealed that students struggled to effectively utilize the library’s research starters. the research starters, which had been designed by different librarians, were arranged using varying layouts and included inconsistent library terminology. for the second wave of fall testing, the research team chose to focus on determining what layout was most intuitive for student use (to read the fall updated usability tasks, see appendix b). however, those tasks, though including a greater number of research starters for usability study participants to interact with, lacked any specific tactic to help determine student preference. as a result, the information technology and libraries december 2023 taming the beast 10 burchfield and possinger research team decided to be more strategic in choosing which research starters would be included in the spring iteration of the study. all published research starters were analyzed and separated into three types. the most popular research starter—those having the greatest number of usage statistics—from each of the three categories was included in the study (to read the spring usability tasks, see appendix c). on each research starter, students were asked to locate the guide’s citation aid and perform one specialized task. the english (engl) 448 class research starter had a top-navigation, two-column design, with a left-hand column of 25 percent and a right-hand column of 75 percent. the right-hand column included a tabbed box with multiple tabs. when asked to search for a specified topic, students easily read and found the corresponding labeled tab (16/19 participants were successful). a list of databases was housed in the left-hand column. this list of databases also included a link to the mla citation aid. while participants noted the list of databases, they did not realize that the citation aid was also included in that list. therefore, the research team made a change in the middle of the spring semester to reconcile this issue. instead of placing the mla citation aid under databases, they separated this into its own box labeled citation help. as a result, students were more easily able to locate the link to the citation aid. the exercise science (exsc) 225 research starter had a top navigation layout, with each page including a single tabbed box in the top column, with videos underneath in three evenly spaced columns. the top navigation style coupled with the tabbed box resulted in each page having two rows of horizontal navigation menus. when students arrived at this research starter, they often responded with “woah,” “wow,” or simply “oh.” these responses indicated that students were overwhelmed by the way the information was organized in the guide. when given specific items to find on the page, such as the apa citation aid, students were able to locate the information from the top navigation menu. this guide did not include a list of applicable databases but rather included links to searches about specific topics. when students were provided with a general task to complete, such as finding a resource on a topic that was not listed verbatim on the research starter, students were less successful in completing the task (only 12/19 students). the digital media (digm) 200 research starter had a side navigation layout. when asked to search for a specified topic, most students did not see that exact topic listed on one of the side navigation tabs but chose instead to utilize the databases listed on the landing page to find an applicable resource. watching students attempt to locate information on the digm 200 guide showed the research team that students did not notice the side navigation features nor the large accordion tabs that were found in the main box of the starter. however, they regularly made use of the list of discipline-specific databases located on the research starter landing page. to conclude the usability study, each participant was asked which of the three class research starters they liked the best or found the easiest to navigate (this question was added later in the spring semester). several participants asserted that the engl 448 starter was the easiest to use (see fig. 8). the research team thought that perhaps there was a bias in the answers because the engl 448 guide was the first guide that the participants interacted with. therefore, the research team rearranged the order the research starters were introduced. the engl 448 guide continued to be singled out as the most efficient layout for a research starter (9/15 students).

discussion and recommendations the research team did not identify a preference among students between top navigation and side navigation, though students’ ability to locate resources showed that the information located on the tabs inside the tabbed boxes was more readily found by students than information located on the side navigation tabs. the research team noticed that students prefer images, icons, and very brief and concise explanations. lengthy descriptions were identified by students as cumbersome and unnecessary. students did not respond well to overwhelming amounts of information in a guide. student responses during the study expressed a desire for clean and simplistic designs, minimal tabs, concise information, guides that did not require scrolling to see all the information, and most importantly, consistency. the most important thing that was learned through this study was that consistency is key to student success. repeatedly students would express confusion as to why each new guide they were shown was different from the previous ones. having struggled to identify where resources were located on the first guide tested during the study, students often vocalized frustration over having to figure out where everything was located all over again. having to relearn how to use the resource that is supposed to be helping them in their research adds too much stress to the student’s cognitive load and makes library resources more of a hindrance to student success than an asset. information technology and libraries december 2023 taming the beast 12 burchfield and possinger limitations finding students who were willing to donate their time to participate in the study was difficult. even with the incentive to be entered into a drawing for a $10 gift card, students were reluctant to give up an hour of their time. as a result, library student assistants who were not scheduled to work at the circulation desk were sometimes pulled from their shelf reading duties to participate in the study. it was not until the spring semester, when the campus ours offered to provide every participant with a $10 gift card, that students began to willingly sign up to be involved in the study. had the head researcher pursued greater fiscal backing in the fall semester, even more students who were not library employees could have been included in the overall study. for future researchers, it is recommended to acknowledge the need for and secure financial support for funding the usability study prior to the onset of the research. the research team quickly noticed that many of the fall student participants understood how to make a room reservation, and as a result, this task was quickly dropped from the study. in addition, the task that asked students to locate a specific book by title was eliminated since all participants were able to complete this task easily and successfully. in hindsight, the research team realized that a large portion of the 10 fall participants were library student assistants. this overabundance of library student assistants in the usability study was a direct result of low student participation in the fall semester. since the participants who were library assistants were overall more familiar with the library’s website and its basic capabilities, it is probable that some of the results collected in the fall semester were slightly skewed. the research team recommends that future researchers take into consideration the users’ background and training and how this may impact their ability to successfully navigate a website. further research when asked to describe their research habits, four of the 19 spring usability study participants reported that they did not use the library’s website or resources at all, and seven reported using the library’s website and resources but only as a secondary source to google and/or google scholar. eight participants reported using the library as their exclusive or main source for research (see fig. 9). interestingly, of those eight who reported using the library as their exclusive or main source for research, six reported having attended a library instruction session as part of their coursework at the institution. only two participants who reported having attended a library instruction session did not use the library as their main source for research. of the 11 students who had not attended a library instruction session, nine reported using the library as a secondary resource or not using the library at all for their research (see fig. 10). for future research, it would be valuable to study the impact of library instruction on the research habits and preferences of students. future studies could focus on identifying any correlation between library instruction and increased library usage or greater self-efficacy in utilizing the library’s resources. information technology and libraries december 2023 taming the beast 13 burchfield and possinger

those with reading or learning disabilities. in conjunction with an earlier study, this paper presents a comparative evaluation of ivy league university library homepages with regard to the americans with disabilities act (ada) mandates. data results from wave and achecker evaluations indicate that although the error of missing form labels still occurs in these websites, other known accessibility errors and issues have been significantly improved from five years ago. introduction an academic library is “a library that is an integral part of a college, university, or other institution of postsecondary education, administered to meet the information and research needs of its students, faculty, and staff.”1 people living with physical disabilities face barriers whenever they enter a library. many blind and visually impaired persons need assistance when visiting a library to do research. in such cases, searching the collection catalog, periodical indexes, and other bibliographic references are frequently conducted by a librarian or the person accompanying that individual to the library. thus, professionals in these institutions can advance the use of academic libraries for the visually impaired, physically disabled, hearing impaired, and people with learning disabilities. library websites are libraries’ virtual front doors for all users pursuing information from libraries. fichter stated that the power of the website is in its popularization.2 access by everyone regardless of disability is an essential reason for its popularization. whether users are students, parents, senior citizens, or elected officials navigating the library website to find resources, or sign up for computer courses at the library, the website can be either a liberating or a limiting experience.3 according to the web accessibility initiative (https://www.w3.org/wai/), website accessibility means that people with disabilities can use the websites. more specifically, website accessibility means that people with disabilities can perceive, understand, navigate, and interact with websites and that they can contribute to the websites. incorporating accessibility into website design enables people with disabilities to enjoy the benefits of websites to the same extent as anyone else in their community. this study evaluated the current state of the accessibility of university websites of the american ivy league university libraries using guidelines established by the americans with disabilities act mailto:youngwf@126.com mailto:andy.zh@126.com mailto:liuy1@southernct.edu mailto:bielefielda1@southernct.edu https://www.w3.org/wai/ information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 2 (ada) for those who are visually or physically impaired or who have reading or learning disabilities. ada’s section 508 and the web content accessibility guidelines (wcag), by the world wide web consortium (w3c) provide guidelines for website developers which define what makes a website accessible to those with physical, sensory, or cognitive disabilities. since a broad array of disabilities are recognized under the ada, websites seeking to be compliant with the ada should use the act’s technical criteria for website design. this study used two common accessibility evaluation tools—wave and achecker—for both section 508 and the wcag version 2.0 level aa. among universities in the united states, the eight ivy league universities—brown, columbia, cornell, dartmouth, harvard, princeton, university of pennsylvania, and yale—all have a long and distinguished history, strict academic requirements, high-quality teaching, and high-caliber students. because of their good reputations, they are expected to lead by example, not only in terms of academic philosophy and campus atmosphere, but also by the accessibility of their various websites. of course, any library website, whether an urban public library or a university library, should be accessible to everyone. hopefully, this study of their accessibility can enlighten other universities on how to better develop and maintain library websites so that individuals with disabilities can enjoy the same level of accessibility to academic knowledge as everyone else. literature review in 1999, schmetzke reported that emerging awareness about the need for accessible website design had not yet manifested itself in the actual design of library websites. for example, at the fourteen four-year campuses within the university of wisconsin system, only 13 percent of the libraries’ top-level pages (homepages plus the next layer of library pages linked to them) were free of accessibility problems.4 has this situation changed in the last twenty years? to answer this question, a number of authors have suggested various methods for evaluating software/hardware for accessibility and usability.5 included in the process of compiling data is “involving the user at each step of the design process. involvement typically takes the form of an interview and observation of the user engaged with the software/hardware.”6 providenti & zai conducted a study in 2007 focused on providing an update on the implementation of website accessibility guidelines of kentucky academic library websites. they tested the academic library homepages of bachelor-degree granting institutions in kentucky for accessibility compliance using watchfire’s webxact accessibility tester and the w3c’s html validator. the results showed that from 2003 to 2007, the number of library homepages complying with basic accessibility guidelines was increasing.7 billingham conducted research on edith cowan university (ecu) library websites. the websites were tested twice, in october 2012 and june 2013, using automated testing tools such as code validators and color analysis programs, resulting in findings that 11 percent of the guidelines for wcag 2.0 level a to level aa were passed in their first test. additionally, there was a small increase in the percentage of wcag 2.0 guidelines passed by all pages tested in the second test. 8 while quite a few research studies focus on library website accessibility rather than the university websites, the conclusions diverge. tatiana & jeremy (2014) tested 509 webpages at a large public university in the northeastern united states using wave (http://wave.webaim.org) and cynthia says (http://www.cynthiasays.com). the results indicated that 51 percent of those webpages http://wave.webaim.org/ http://www.cynthiasays.com/ information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 3 passed automated website accessibility tests for section 508 compliance with cynthia says. however, when using wave for wcag priority 1 compliance, which is a more rigorous evaluation level, only 35 percent passed the test.9 maatta smith reported that not one of the websites of 127 us members of the urban library council (ulc) was without errors or alerts, with the average number of errors being 27.10 such results were similar with liu.11 12they also found that about half (58 of 127) of the urban public libraries provided no information specifically for individuals with disabilities. of the 127 websites, some were confusing by using the variety of verbiage to suggest services for individuals with disabilities. sixty-six of them provide some information about services within the library for individuals with disabilities. the depth of the information varied, but in all instances contact information was included for additional assistance. liu, bielefield, and mckay examined 122 library homepages of ulc members and reported on three main aspects. first, only seven of them presented as error free when tested for compliance with the 508 standards. the highest percentage of errors occurred in accessibility sections 508(a) and 508(n). second, the number of issues was dependent on the population served. that means libraries serving larger populations tend to have more issues with accessibility than those serving smaller ones. third, the most common errors were missing label and contrast errors, while the highest number of alerts was related to the device-dependent event handler, which means that a keyboard or mouse is a necessary piece of equipment to initiate a desired transaction.12 although they were interested in overall website accessibility, theofanos and redish focused their research on the visually impaired website user. the authors investigated and revealed six reasons to bridge the gap between accessibility and usability. the six reasons were: 1. disabilities affect more people than you may think worldwide. 750 million people have a disability, and three of every ten families are touched by a disability. in the united states, one in five have some kind of disability, and one in ten have a severe disability. that’s approximately 54 million americans. 2. it is a good business. according to the president’s committee on the employment of people with disabilities, the discretionary income of people with disabilities is $175 billion. 3. the number of people with disabilities and income to spend is likely to increase. the likelihood of having a disability increases with age, and the overall population is aging. 4. the website plays an important role and has significant benefits for people with disabilities. 5. improving accessibility enhances usability for all users. 6. it is morally the right thing to do.13 lazar, dudley-sponaugle, and greenidge validated that most blind users were just as impatient as most sighted users. they want to get the information they need as quickly as possible. they don’t want to listen to every word on the page just as sighted users do not read every word.14 similarly, foley found that using automated validation tools did not ensure complete accessibility. students with low vision found many of the pages hard to use even though they were validated.15 outcomes of all the research revealed that most university library websites have developed a policy on website accessibility, but the policies of most universities had deficiencies.16 library staff information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 4 must be better informed and trained to understand the tools available to users, and when reviewing web pages, the audiences of all kinds must be considered.17 research design and methods this study, as a continuing effort from an earlier study on urban library websites, made use of content analysis methodology to examine the website accessibility of the university libraries against the americans with disabilities act (ada), with a focus on those with visual or cognitive disabilities.18 under the ada, people with disabilities are guaranteed access to all postsecondary programs and services. the evaluation of accessibility focuses on the main pages of these university library websites, as shown in table 1, because these homepages considerably demonstrate the institution’s best effort or, at least, most recent redesigns. it was the intent of the authors of this research to reveal the current status of the ivy league library homepages’ accessibility and the importance that ivy league universities attach to the accessibility of their websites. commonly recognized website evaluators (wave, achecker, and cynthia says), along with other online tools, evaluate a website's accessibility by checking its html and xml code. wave and achecker were selected for this study for the robustness of their evaluation based on w3c guidelines, comprehensiveness of evaluation reporting, and ready availability to any institution or individual conducting website evaluations. wave is a web evaluation tool that was utilized to check websites against section 508 standards and wcag 2.0 guidelines. this assessment was conducted by entering a uniform research locator, url, or website address in the search box. the evaluation tool provided a summary of errors, alerts, features, structural elements, html5 and aria. achecker is a tool to check single html page content for conformance with accessibility standards to ensure the content can be accessed by everyone. it produces a report of all accessibility problems for the selected guidelines by three types of problems: known problems, likely problems and potential problems. both wave and achecker help website developers make their website content more accessible. data from different periods were compared to show statistically whether enough attention was paid to accessibility issues by the ivy league university systems. the study team collected the first data set in february 2014, using wave for section 508. in 2018, achecker accessibility checker was used for both section 508 and wcag 2.0 aa. the access board published new requirements for information and communication technology covered by section 508 of the rehabilitation act (https://www.access-board.gov/guidelines-andstandards/communications-and-it/about-the-ict-refresh) on january 18, 2017. the latest wcag 2.0 guidelines were updated on september 5, 2013 (https://www.w3.org/tr/wcag2ict/). while the wave development team indicated that they have updated the indicators in wave regarding wcag 2.0, the current indicators regarding section 508 refer to the previous technical standards for section 508, not the updated 2017 ones. according to achecker.ca, the versions of the section 508 standards and wcag 2.0 aa guidelines used were published on march 12, 2004 and june 19, 2006, respectively, with neither being the latest versions. this study centered on three research questions:

library. similar results in numbers of the five categories are presented in the library homepages of brown university, columbia university, and cornell university. interestingly, wave indicates more errors and alerts on the homepage of yale university. figure 1. wave results for section 508 standards. in order to determine the accuracy of the results, the team also used achecker to reevaluate these homepages in the year 2018. known problems as the category in achecker are as serious as errors in wave. they have been identified with certainty as accessibility barriers by the website information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 6 evaluators and need to be fixed. likely problems are problems that could be barriers which require a human to decide whether there is a need to fix them. achecker cannot identify potential problems and requires a human to confirm if identified problems need remediation. figure 2 shows the numbers for each category as detected by achecker on june 18, 2018, on the eig ht ivy league university libraries’ homepages. the library homepage of the university of pennsylvania was found to contain the most, which was the same as the result from wave. however, among the seven remaining libraries’ homepages, the homepage of harvard university library displayed the same number of problems as the university of pennsylvania detected by achecker. figure 2. achecker results for section 508 standards. there was significant improvement between 2014 and 2018 the results of this research from wave for section 508 standards signify a significant shift in the accessibility of these websites between the years of 2014 and 2018. among the five wave detection categories in the eight library homepages, the total of errors and alerts decreased during this period. for instance, the total number of errors was 36 in 2014 decreasing to 11 in 2018, and the number of alerts decreased from 141 to 14. figure 3 shows the number of errors in each library homepage, and figure 4 shows the number of alerts. they all show a downward trend from 2014 to 2018. but features, structural elements and html/aria were all on the rise when comparing the two years’ data sets. the green sections in table 2 indicate a decrease of the numbers in three categories from 2014 to 2018, and the yellow sections indicate an increase in numbers. these data results revealed that errors and alerts, the most common problems related to access, had been better controlled during these years, while others might still remain unchanged. information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 7 figure 3. change of errors from 2014 to 2018. figure 4. change of alerts

homepages accessible? | liu 8 figure 5. occurrences of specific error per specific 508 standards. the term error refers to accessibility errors that need to be fixed. missing form label was the highest frequency error type shown. only two types of errors occurred in ivy league university libraries’ homepages. but these errors didn’t appear on every homepage. there are several errors in some homepages while others had no errors. for example, linked image missing alternative text occurred on the library homepage of harvard university twice. table 3 shows the distribution of errors in eight homepages. table 3. distribution of errors in eight homepages. missing form label linked image missing alternative text brown university library columbia university libraries 1 cornell university library dartmouth library 3 harvard library 2 princeton university library penn libraries 1 yale university library 4 missing form label is listed in section 508 (n) and means there is a form control without a corresponding label. this is important because if a form control does not have a properly associated text label, the function or purpose of that form control may not be presented to sc reen reader users. linked image missing alternative text occurred only in the harvard library homepage among the eight ivy league university libraries’ homepages. it indicated that an image without alternative text results in an empty link. if an image is within a link that does not provide alternative text, a screen reader has no content to present to the user regarding the function of the link. these website accessibility issues may be easy fixes and considered minor to some; however, if they are not detected, they are major barriers for persons living with low vision or blindness. as a result, users are left at a disadvantage because they are lacking critical information to successfully fulfill their needs. examples of such error icons in wave are displayed in figures 6 and 7.

number of errors that occurred in each library homepage. the average number of errors for each homepage was 1.375. yale university library homepage had the most errors with a total of four. library homepages of brown university, cornell university and princeton university performed best with zero errors. figure 8. the total of errors in ivy league libraries’ homepages. information technology and

accessibility. figure 9 shows there are six different kinds of alerts that were identified based on the specific requirements contained in section 508 of the rehabilitation act. figure 9. occurrences of specific alert per specific 508 standards. the noscript element was the most encountered alert issue. alerts that wave reports need close scrutiny, because they likely represent an end-user accessibility issue. the noscript element is related to the 508 (l) requirement and means a noscript element is present when javascript is disabled. for users of screen readers and other assistive technologies, almost all have javascript enabled, so noscript cannot be used to provide an accessible version of inaccessible scripted content. skipped heading level ranked was second in number. the importance of headings is in their provision of document structure and facilitation of keyboard navigation for users of assistive technology. these users may be confused or they may experience difficulty navigating when heading levels are skipped. examples of icons of these alerts, evaluated by wave, indicated these noscript elements as being to accessibility, as shown in figures 10 and 11.

skipped heading level icon from dartmouth library homepage. a total of fourteen alert problems were detected. figure twelve illustrates the number of alerts that occurred on each library homepage. on average, there were 1.75 alerts present on the eight websites. the library homepages of yale university and the university of pennsylvania had the most alerts with 4 on each site. only the brown university library’s homepage had zero alerts. figure 12. the total of alerts in ivy league libraries’ homepages. linked image with alternative text was the most frequently found feature issue features as a category of issues indicates conditions of accessibility that probably need to be improved and usually require further verification and manual fixing. for example, if a feature is detected on a website, it means that further manual verification is required to confirm its accessibility. figure 13 shows the number of features that were identified, based on the specific requirement contained in section 508 of the rehabilitation act. information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 12 figure 13. occurrences of specific features per specific 508 standards. linked image with alternative text, which is a 508 (a) requirement, was shown to be the most encountered features issue. this means that an alternative text should be presented for an image that is within a link. by including appropriate alternative text on an image within a link, the function and purpose of the link and the content of the image are available to screen reader users even when images are unavailable. another high occurring feature was form label, which means a form label is present and associated with a form control. a properly associated form label is presented to a screen reader user when the form control is accessed. these evaluation steps were the same ones used for errors and alerts. example icons of features evaluated

specific requirements in section 508, the authors comparatively examined these eight university homepages using both wave and achecker from one site to another synchronously in april and again in june 2019. there are sixteen principles in section 508. they are arranged from a to p. tables 4a–4d indicate issues for these section 508’s requirements in the eight universities’ homepages respectively. except the requirement g for yale library homepage which shows one issue in achecker, in neither wave nor achecker during the time we conducted our examination, there was no issue found for the seven requirements (b, e, f, h, i, k, and p) below: b. equivalent alternatives for any multimedia presentation shall be synchronized with the presentation; e. redundant text links shall be provided for each active region of a server-side image map; f. client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape; h. markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers; i. frames shall be titled with text that facilitates frame identification and navigation; k. a text-only page, with equivalent information or functionality, shall be provided to make a website comply with the provisions of this part, when compliance cannot be accomplished in any other way. the content of the text-only page shall be updated whenever the primary page changes; p. when a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required. the results tabulated in tables 4a–4d indicate that these seven section 508 requirements perhaps are not problematic to the websites. conclusions based on the results, this study determined that the eight ivy league universities’ homepages exhibited some issues with accessibility for people with disabilities. considerable effort is necessary to ensure their websites ready to meet the challenges and future needs of web accessibility. users with visual impairments can navigate a website only when it is designed to be accessible with other assistive technology. while each institution presented both general and comprehensive coverage of services for users with disabilities, it would have been more practical and efficient if specific links were posted on the homepage. according to the american foundation for the blind (https://www.afb.org), “usability” is a way of describing how easy a website is to understand and use. accessibility refers to how easily a website can be used, understood, and accessed by people with disabilities. https://www.afb.org/ information technology and libraries june 2020 are ivy league library website homepages accessible? | liu 17 this study has concluded that expertise and specialized training and skill are still needed in th is area. principles of accessible website design must be introduced and taught, underscoring that design matters for people with disabilities just as it does in the physical environment. as highlighted earlier through the evaluation tool wave, most of the problems detected can be fixed with provided solutions. a frequent review is critical and websites should be assessed at a minimum on a yearly basis for accessibility compliance. there is much to be done if accessibility is to be realized for everyone. limitations the authors recognize that this study, using free website accessibility testing tools, has certain limitations. as wave remarked in their help page, the aim of website developers is not to get rid of all identified problem categories except errors that need to be fixed, but to determine whether a website is accessible. at the time of writing neither wave nor achecker were updated with the latest general wcag 2.1 aa rules. while the version of wcag 2.1 is expected to provide new guidelines for making websites even more accessible, more careful and comprehensive studies against the wcag 2.1 aa rules could further assist university library professionals and their website developers to provide those with disabilities with accessible websites. moreover, while it is effective to conduct these machine-generated evaluations, it is equally important that researchers check the issues manually to impose human analysis in determining the major issues with content. endnotes 1 joan m. reitz, odlis: online dictionary for library and information science.

alternative text was the most frequently found feature issue a few 508 standards deviate from comparison between two evaluators conclusions limitations endnotes hutchinson this study focuses on the adoption and use of wireless technology by medium-sized academic libraries, based on responses from eighty-eight institutions. results indicate that wireless networks are already available in many medium-sized academic libraries and that respondents from these institutions feel this technology is beneficial. w ireless networking offers a way to meet the needs of an increasingly mobile, tech-savvy student population. while many research libraries offer wireless access to their patrons, academic libraries serving smaller populations must heavily weigh both the potential benefits and disadvantages of this new technology. will wireless networks become essential components of the modern academic library, or is this new technology just a passing fad? prompted by plans to implement a wireless network at the houston cole library (hcl) (jacksonville state university’s [jsu’s] library), which serves a student enrollment close to ten thousand, this study was conducted to gather information about whether libraries similar in size and mission to hcl have adopted wireless technology. the study also sought to find out what, if any, problems other libraries have encountered with wireless networks and how successful they have perceived those networks to be. other questions addressed include level of technical support offered, planning, type of equipment used to access the network, and patron-use levels. � review of literature a review of the literature on wireless networks revealed a number of articles on wireless networks and checkout programs for laptop computers at large research institutions. seventy percent of major research libraries surveyed by kwon and soules in 2003 offered some degree of wireless access to their networks.1 no articles, however, specifically addressed the use of wireless networks in medium-sized academic libraries. many articles can also be found on wireless-network use in medical libraries and other institutions. library instruction using wireless classrooms and laptops has been another subject of inquiry as well. breeding wrote that there are a number of successful uses for wireless technology in libraries, and a wireless local area network (wlan) can be a natural extension of existing networks. he added that since it is sometimes difficult to install wiring in library buildings, wireless is more cost effective.2 a yearly survey conducted by the campus computing project found that the number of schools planning for and deploying wireless networks rose dramatically from 2002 to 2003. “for example, the portion of campuses reporting strategic plans for wireless networks rose to 45.5 percent in fall 2003, up from 34.7 percent in 2002 and 24.3 percent in 2001.”3 the use of wireless access in academia is expected to keep growing. according to a summary of a study conducted by the educause center for applied research (ecar), the higher-education community will keep investing in the technology infrastructure, and institutions will continue to refine and update networks. the move toward wireless access “represents a user-centered shift, providing students and faculty with greater access than ever before.”4 in an article on ubiquitous computing, drew provides a straightforward look at how wlans work, security issues, planning, and the uses and ramifications of wireless technology in libraries. he suggests, “perhaps one of the most important reasons for implementing wireless networking across an entire campus or in a library is the highly mobile lifestyle of students and faculty.” the use of wireless will only increase with the advent of new portable devices, he added. wireless networking is the best and least expensive way for students, faculty, and staff to take their office with them wherever they go.5 the circulation of laptop computers is a frequent topic in the available literature. the 2003 study by kwon and soules primarily focused on laptop-lending services in academic-research libraries. fifty percent of the institutions that responded to their survey provided laptops for checkout. the majority indicated moderate-to-high use of laptop services. positive user response and improved “public reputation, image, and relations” were the greatest advantages reported with laptop circulation. the major disadvantages associated with these services were related to labor and cost.6 a study of laptop checkout service at the mildred f. sawyer library at suffolk university in boston revealed that laptop usage was popular during the fall semester of 1999. students checked out the computers to work on group projects. a laptop area was set aside on one library floor to provide wired internet access for eight users. however, students wanted to use the laptops anywhere, not one designated place. the wired laptop areas were not popular, dugan wrote, adding that “few students used the wired area and the wires were repeatedly stolen or intentionally broken.” an interim phase involved providing wireless network cards for checkout wireless networks in medium-sized academic libraries: a national survey paula barnett-ellis and laurie charnigo paula barnett-ellis (pbarnett@jsucc.jsu.edu) is health and sciences librarian, and laurie charnigo (charnigo@jsucc .jsu.edu) is education librarian at houston cole library, jacksonville state university, alabama. wireless networks in medium-sized academic libraries | barnett-ellis and charnigo 13 14 information technology and libraries | march 2005 to encourage patrons to use their own laptops, and, when a wireless network was put into place in the fall of 2000, demand exceeded the number of available laptops for checkout.7 � method a survey (see appendix) was designed to find out how many libraries similar in size and mission to hcl have adopted wireless networks, the experiences they have encountered in offering wireless access, and, most importantly, whether they felt the investment in wireless technology has been worth the effort.8 the national center for education statistic’s academic library peer comparison tool, a database composed of statistical information on libraries throughout the united states, was used to select institutions for this study. a search on this database retrieved eighty-eight academic libraries that met two criteria: full-time enrollments of between five thousand and ten thousand, and classification by the carnegie classification of higher education as master’s colleges and universities i.9 the survey was administered to those thought most likely to be responsible for systems in the library; they were selected from staff listings on library web sites (library systems administrator, information tech-nology [it] staff). if such a person could not be identified, the survey was sent to the head of library systems or to the library director. the survey was divided into the following sections: implementation of wireless network, planning and installation stages, user services, technical problems, and benefits specific to use of network. surveys were mailed out in march 2004. an internet address was provided in the cover letter if participants wished to take the survey online rather than return it by mail. an e-mail reminder with a link to the online survey was sent out three weeks after the initial survey was mailed. all letters and e-mails were personalized, and a self-addressed stamped envelope and a ballpoint pen with the jsu logo were included with the mail surveys. in the e-mail reminder, the authors offered to share the results of the project with anyone who was interested, and received several enthusiastic responses. � results a total of fifty-three completed surveys were returned, resulting in a response rate of 60 percent. the overwhelming majority (85 percent) responded that their library offered wireless-network access. even if the thirty-five surveys that were not returned had reported that wireless networks were not available, more than 50 percent would still have offered wireless networks. survey results also pointed to the newness of the technology. only four of the fifty-three institutions have had wireless networks for more than three years. the majority (73 percent) has implemented wireless networks just within the last two years. when asked to identify the major reasons for offering wireless networks to their patrons, the three responses most chosen were: (1) to provide greater access to users; (2) the flexibility of a network unfettered by the limitations of tedious wiring; and (3) to keep up with technological innovation (see table 1). least significant factors in the decision to implement wireless networks were cost; use by library faculty and staff; to aid in bibliographic instruction; and use for carrying out technical services (taking inventory). somewhat to the authors’ surprise, wireless use in bibliographic instruction was not high on the list of reasons for installing a wireless network, identified by only 9 percent of respondents. the benefits of wireless for library instruction was stressed in the literature by mathias and heser and patton.10 in addition to obtaining an instrument for gauging how many libraries similar in scope and size to hcl have implemented wireless networks and why they chose to do so, questions on the survey were also designed to gather information on planning and implementation, user services, technical problems, and perceived benefits. � planning and implementation although tolson mentions that some schools have used committees composed of faculty, staff, and students to look into the adoption of wireless technology, responses from this survey indicated that the majority (60 percent) of the libraries did not form committees specifically for the planning of their wireless networks.11 in addition, 49 percent of the libraries took fewer than six months to plan for implementation of a network, 37 percent required six months to one year, and 15 percent reported more than one to two years. actual time spent on installation and configuration of wireless networks was relatively short, 98 percent indicating less than one year (see table 2 for specific times). one of the most important issues to consider when planning to implement a wireless network is extent of coverage—where wireless access will be available. survey responses revealed varying degrees of wireless coverage among institutions. twenty percent had campus-wide access, 55 percent had some level of coverage throughout the entire library, 37 percent provided a limited range of coverage outside the building, and 20 percent offered access only in certain areas within the library. according to a bulletin published by ecar, institutions vary in their approaches to networking depending on enrollment. smaller colleges and universities with fewer than ten thousand students are “more likely to implement campuswide wireless networks from the start. larger institutions are more likely to implement wireless technology in specific buildings, consistent with a desire to move forward at a modest pace, as resources and comfort with the technology grow.”12 questions on the survey also queried respondents about the popularity of spaces in the library where users access the library’s wireless network. answers revealed that the most popular areas for wireless access are study carrels, tables, and study rooms. nineteen percent indicated that accessing wireless networks in the stacks is popular. of particular concern to hcl, a thirteen-story building, was how the environment of the library would accommodate a wireless network. a thorough site survey is important to locate the best spots within the library to install access points and to determine whether there are architectural barriers in the building that might interfere with access. the majority of survey respondents indicated that the site survey conducted in their library for a wireless network was carried out by their academic institution’s it staff (59 percent). while library staff conducted 35 percent of site surveys, only 17 percent were conducted by outside companies. � user services an issue to be addressed by libraries deciding to go wireless is whether laptop computers should also be provided for checkout in the library. after all, it might be hard to justify the usefulness of a wireless network if users do not have access to laptops or other hardware with wireless capabilities. while one individual reported working at a “laptop university” in which campuswide wireless networking exists and all students are required to own laptops, not all college students will have that luxury. in order to provide more equal access to students, checking out laptops has become an increasingly common service in academic libraries. seventy percent of this survey’s respondents whose institutions offered wireless access also made laptops available for checkout. comments made throughout the survey seemed to imply that while checking out laptops to patrons is an invaluable complement to offering wireless access, librarians should be prepared for a myriad of hassles that accompany laptop checkout. wear and tear of laptops, massive battery use, cost of laptops, and maintenance were some of the biggest problems reported. one participant, whose institution decided to stop offering laptops for checkout to patrons in the library, wrote, “it required too much staff time to maintain and we decided the money was better spent elsewhere. the college now encourages students to purchase a laptop [instead of] a full-sized pc.” one participant worried that the rising use of laptops in his library would lead to the obsolescence of its more than one hundred wired desktops, writing, “our desktops are very popular and we think having them is one of the reasons our gate count has increased in recent years. what happens when everyone has a laptop?” the number of laptops checked out in the libraries varied. the majority of libraries had purchased between one and thirty laptops available for checkout (see table 3). three institutions had more than forty-one laptops available for checkout. one library could boast that it had sixty laptops available for checkout with twelve pagers to notify students waiting in line to use laptops. when asked about the use of laptops in libraries, 46 percent table 1. main reasons for implementing a wireless network in absolute numbers and percentages reasons for implementing

wireless networks in medium-sized academic libraries | barnett-ellis and charnigo 15 16 information technology and libraries | march 2005 observed moderate use, while 32 percent reported heavy use of laptops. only 3 percent indicated that they hardly ever noticed use of laptops in the library. for those students who chose to bring their own laptop to access the library’s wireless network, half of the institutions surveyed required students to purchase their own network-interface cards for their laptops, while 19 percent allowed students to check them out from the library. in addition to laptops, personal digital assistants, (pdas) were listed by 37 percent of respondents as devices that may access wireless networks. one librarian indicated that cell phones could access the wireless network in his library. fiftysix percent of respondents indicated that users are able to print to a central printer in the library from their wireless device. an important consideration for implementing a wireless network is how users will authenticate. authentication protocol is defined by the microsoft encyclopedia of networking as “any protocol used for validating the identity of a user to determine whether to grant the user access to resources over a network.”13 authentication methods listed by the institutions surveyed varied greatly and the authors could not identify all of them. methods mentioned were lightweight directory access protocol (ldap), virtual private network (vpn), and media access control (mac) addresses, bluesocket, remote authentication dial in user service (radius), pluggable graphical identification and authentication (pgina), protected extensive authentication protocol (peap), and e-mail logins. out of the thirty-nine responses to this question, seven individuals indicated that they do not require any type of authentication at the present. although some individuals noted that they are planning to enable some type of authentication in the future, one participant suggested that there were ethical issues involved in requiring users to authenticate. this person argued that “anonymous access to information is valued” and praised his institution’s current policy of allowing “anyone who can find the network” to use it. a concern about offering wireless network access in the library is how library staff will be prepared to handle the flood of technical questions that are likely to ensue. the level of technical support offered to users varied among the institutions surveyed. more than half of the respondents indicated that users receive help specifically from it staff or from the campus computer center. thirtynine percent of users received help from the reference desk, while 19 percent received help from circulation staff. thirty-three percent of the responding institutions offered technical help from a web site, while 7 percent indicated that they did not offer any type of technical support to users. technical problems the technical problems most often encountered with wireless networks centered on architectural barriers that cause black-outs or slow-spots where wireless access fails. this confirms the importance of carrying out thorough site surtable 2. total length of time taken to completely configure and install the wireless network time to install and total number of percent of responses

to installation of access points. site surveys may be carried out by companies specially equipped and trained to determine where access points should be installed, the most appropriate type of antennae (directional or omnidirectional), and how many access points are needed to provide the greatest amount of coverage. configuration of the network was the second most highly reported problem associated with installing wireless networks, seeming to suggest the need for librarians to coordinate their efforts and rely on the knowledge provided by the it coordinator (or similar type of personnel) within their institution. lack of technical support available to users, slow speed, and authentication were also indicated as technical problems most encountered (see table 4). integrating the wireless network with the existing wired network was the least-mentioned problem associated with wireless networks. although security problems, particularly concerning wired equivalency protocol (wep) vulnerabilities, have been pointed out as one of the major drawbacks of a wireless network, the majority of users had not as yet experienced security problems. although one participant wrote, “don’t be too casual about the security risks,” another individual wrote, “talk to your networking department,” as many of them are overly worried about security. perceived benefits respondents reported that the number-one benefit of offering wireless access was user satisfaction. giving patrons the ability to use their laptops anywhere in the library and do multiple tasks from one machine is simply becoming what more and more users expect. the secondlargest benefit revolved around flexibility and ease of use due to the lack of wires. thirty-five percent indicated that allowing students to roam the stacks while accessing the network was a significant benefit. although a few studies have suggested the promise of wireless networks for aiding bibliographic instruction, only 9 percent of respondents indicated this as a benefit of wireless technology. use of wireless technology for instruction, it might be recalled, was not a significant factor noted by respondents in the decision to implement a wireless network. likewise, use of this type of network to carry out technical services (such as inventory) was also low on the scale of benefits. seventy-three percent of users claimed that wireless networks have thus far been worth the cost-benefit ratio. while 70 percent indicated moderate to heavy use of the wireless network, 27 percent reported low usage. when asked what advice they would give to others considering adopting wireless networks in their libraries, the overwhelming majority of responses were positive, recommending that hcl take the plunge. as one individual wrote, “offer it and they will come. it has really increased the usage of our library.” other individuals noted that it is simply necessary to offer wireless access to keep up with technological innovation, and that students expect it. the most significant warning, however, revolved around checkout and maintenance of laptops, which, from the results of this survey, seems be both a big advantage and a headache. several individuals echoed the importance of doing site surveys to test bandwidth limitations and access. one particularly energized participant, using multiple exclamations for emphasis, shared a plethora of advice. “throttle connection speeds! allow only http access! block ports and unnecessary protocols! secure your network and disallow unauthenticated users! use

wireless-access implementation gleaned from this survey fell under the following categories: � be aware of slower speed � create a policy and guide for users � do it because more users are going wireless, it is necessary to keep up with technological innovation, and because students love it � provide plenty of access points � install access points in appropriate places � ensure continuous connectivity by allowing overlap between access points � purchase battery chargers and heavy-duty laptops with extended warranties � get support from it staff for planning and maintenance � offering wireless will increase library usage � perform or have an expert perform a careful site survey and do lots of testing to locate dead or slow spots in the library due to architectural barriers � enable some type of authorization � be aware of security concerns � although the majority of participants’ networks (70 percent) support 802.11b (which allows for throughput up to 11 megabits per second), a few participants suggest using the 802.11g standard (up to 54 megabits per second) because it is “the fastest” and “backwards compatible to 802.11b” � conclusion though it is a relatively new technology, this study found that a surprisingly large number of medium-sized academic libraries are already offering wireless access. not only are they offering wireless access, but they are also providing patrons with laptops for checkout in the library. although actual use of the network by patrons was not determined through survey responses (as individuals were only asked about their observations of network use), the comments and answers were overwhelmingly positive and enthusiastic about this new technology. problems that have been encountered with wireless networks largely revolve around configuration, slow speed, and laptop checkout. although much of the literature focuses on security issues that accompany wireless networking, few individuals reported problems with security. college and university students, like the rest of society, are becoming increasingly mobile. more often, they want access to library networks and the internet wherever they happen to be studying or working on group projects, not merely in computer labs or designated study areas. the majority of the libraries in this study are accommodating these students’ needs by offering wireless access. according to breeding, wireless networking is a rapidly growing niche in the networking world, and mobile computer users will become a larger and larger part of any library’s clientele.14 to encourage patrons to continue visiting them, academic libraries, large and small, should attempt to meet the demand for wireless access if at all possible. references and notes 1. myoung-ja lee kwon

our main website, our three branch library websites; remote article databases, local custom databases, local digital collections, special collections, other remotely hosted resources (such as libguides), and others. the number of these resources, as well as the total volume of content offered by the libraries, has grown over time (figure 1), while access provisions have not kept pace in terms of usability. in light of this dilemma, the libraries and various units within have deployed finding and search tools that provide browsing and searching access to certain subsets of these resources, depending on criteria such as n the type of resource; n its place within the libraries’ organizational structure; n its place within some arbitrarily defined topical categorization of library resources; n the perceived quality of its content; and n its uniqueness relative to other resources. these tools tend to be organization-centric rather than patron-centric, as they are generally provisioned in relative isolation from each other without placing as much emphasis on the big picture (figure 2). the result is, from the patron’s perspective, a disaggregated mass of information and scattered finding tools that, to varying degrees, each accomplishes its own specific goals at the expense of macro-level findability. currently, a comprehensive search for a given subject across as many library resources as possible might involve visiting a half-dozen interfaces or more—each one predicated upon awareness of each individual interface, its relation to the others, and figure 1. “silos” in the library figure 2. organization-centric resource provisioning alex a. dolski (alex.dolski@unlv.edu) is web & digitization application developer at the university of nevada las vegas libraries. information discovery insights gained from multipac | dolski 173 the characteristics of its specific coverage of the corpus of library content. our library website serves as the de facto gateway to our electronic, networked content offerings. yet usability studies have shown that findability, when given our website as a starting point, is poor. undoubtedly this is due, at least in part, to interface fragmentation. test subjects, when given a task to find something and asked to use the library website as a starting point, fail outright in a clear majority of cases.1 multipac is a technical prototype that serves as an exploration of these issues. while the system itself breaks no new technical ground, it brings to the forefront critical issues of metadata quality, organizational structure, and long-term planning that can inform future actions regarding strategy and implementation of potential solutions at unlv and elsewhere. yet it is only one of numerous ways that these issues could be addressed.2 in an abstract sense, multipac is biased toward principles of simplification, consolidation, and unification. in theory, usability can be improved by eliminating redundant interfaces, consolidating search tools, and bringing together resource-specific features (e.g., opac holdings status) in one interface to the maximum extent possible (figure 3). taken to an extreme, this means being able to support searching all of our resources, regardless of type or location, from a single interface; abstracting each resource from whatever native or built-in user interface it might offer; and relying instead on its data interface for querying and result-set gathering. thus multipac is as much a proof-of-concept as it is a concrete implementation. n background: how multipac became what it is multipac came about from a unique set of circumstances. from the beginning, it was intended as an exploratory project, with no serious expectation of it ever being deployed. our desire to have a working prototype ready for our discovery mini-conference meant that we had just six weeks of development time, which was hardly sufficient for anything more than the most agile of table 1. some popular existing library discovery systems name company/institution commercial status aquabrowser serials solutions commercial blacklight university of virginia open-source (apache) encore innovative interfaces commercial extensible catalog university of rochester open-source (mit/gpl) libraryfind oregon state university open-source (gpl) metalib ex libris commercial primo ex libris commercial summon serials solutions commercial vufind villanova university open-source (gpl) worldcat local oclc commercial table 2. some existing back-end search servers name company/institution commercial status endeca endeca technologies commercial idol autonomy commercial lucene apache foundation open-source (apache) search server microsoft commercial search server express microsoft free solr (superset of lucene) apache foundation open-source (apache) sphinx sphinx technologies open-source (gpl) xapian community open-source (gpl) zebra index data open-source (gpl) 174 information technology and libraries | december 2009 development models. the resulting design, while foundationally solid, was limited in scope and depth because of time constraints. another option, instead of developing multipac, would have been to demonstrate an existing open-source discovery system. the advantage of this approach is that the final product would have been considerably more advanced than anything we could have developed ourselves in six weeks. on the other hand, it might not have provided a comparable learning opportunity. n survey of similar systems were its development to continue, multipac would find itself among an increasingly crowded field of competitors (table 1). a number of library discovery systems already exist, most backed by open-source or commercially available back-end search engines (table 2), which handle the nitty-gritty, low-level ingestion, indexing, and retrieval. these lists of systems are by no means comprehensive and do not include notable experimental or research systems, which would make them much longer. n architecture in terms of how they carry out a search, meta-search applications can be divided into two main groups: distributed (or federated search), in which searches are “broadcast” to individual resources that return results in real time (figure 4); and harvested search, in which searches are carried out against a local index of resource contents (figure 5).3 both have advantages and disadvantages beyond the scope of this article. multipac takes the latter approach. it consists of three primary components: the search server, the user interface, and the metadata harvesting system (figure 6). figure 4. the federated search process figure 5. the harvested search process figure 6. the three main components of multipac figure 3. patron-centric resource provisioning information discovery insights gained from multipac | dolski 175 n search server after some research, solr was chosen as the search server because of its ease of use, proven library track record, and http–based representational state transfer (rest) application programming interface (api), which improves network-topological flexibility, allowing it to be deployed on a different server than the front-end web application—an important consideration in our server environment.4 jetty—a java web application server bundled with solr—proved adequate and convenient for our needs. the metadata schema used by solr can be customized. we derived ours from the unqualified dublin core metadata element set (dcmes),5 with a few fields removed and some fields added, such as “library” and “department,” as well as fields that support various multipac features, such as thumbnail images, and primary record urls. dcmes was chosen for its combination of generality, simplicity, and familiarity. in practice, the solr schema is for finding purposes only, so whether it uses a standard schema is of little importance. n user interface the front-end multipac system is written in php 5.2 in a model-view-controller design based on classical object design principles. to support modularity, new resources can be added as classes that implement a resource-class interface. the multipac html user interface is composed of five views: search, browse, results, item, and list, which exist to accommodate the finding process illustrated in figure 7. each view uses a custom html template that can be easily styled by nonprogrammer web designers. (needless to say, judging by figures 8–12, they haven’t been.) most dynamic code is encapsulated within dedicated “helper” methods in an attempt to decouple the templates from the rest of the system. output formats, like resources, are modular and decoupled from the core of the system. the html user interface is one of several interfaces available to the multipac system; others include xml and json, which effectively add web services support to all encompassed resources—a feature missing from many of the resources’ own built-in interfaces.6 n search view search view (figure 8) is the simplest view, serving as the “front page.” it currently includes little more than a brief introduction and search field. the search field is not complicated; it is, in fact, possible to include search forms on any webpage and scope them to any subset of resources on the basis of facet queries. for example, a search form could be scoped to las vegas–related resources in special collections, which would satisfy the demand of some library departments for custom search engines tailored to their resources without contributing to the “interface fragmentation” effect discussed in the introduction. (this would require a higher level of metadata quality than we currently have, which will be discussed in depth later.) because search forms can be added to any page, this view is not essential to the multipac system. to improve simplification, it could be easily removed and replaced with, for example, a search form on the library homepage. n browse view browse view (figure 9) is an alternative to search view, intended for situations in which the user lacks a “concrete target” (figure 7). as should be evident by its appearance, figure 7. the information-finding process supported by multipac figure 8. the multipac search view page 176 information technology and libraries | december 2009 this is the least-developed view, simply displaying facet terms in an html unordered list. notice the facet terms in the format field; this is malprocessed, marc– encoded information resulting from a quick-and-dirty extensible stylesheet language (xsl) transformation from marcxml to solr xml. n results view the results page (figure 10) is composed of three columns: 1. the left column displays a facet list—a feature generally found to be highly useful for results-gathering purposes.7 the data in the list is generated by solr and transformed to an html unordered list using php. the facets are configurable; fields can be made “facetable” in the solr schema configuration file. 2. the center column displays results for the current search query that have been provided by solr. thumbnails are available for resources that have them; generic icons are provided for those that do not. currently, the results list displays item title and description fields. some items have very rich descriptions; others have minimal descriptions or no descriptions at all. this happens to be one of several significant metadata quality issues that will be discussed later. 3. the right column displays results from nonindexed resources, including any that it would not be feasible to index locally, such as google, our article databases, and so on. multipac displays these resources as collapsed panes that expand when their titles are clicked and initiate an ajax request for the current search query. in a situation in which there might be twenty or more “panes” to load, performance would obviously suffer greatly if each one had to be queried each time the results page loaded. the on-demand loading process greatly speeds up the page load time. currently, the right column includes only a handful of resource panes—as many as could be developed in six weeks alongside the rest of the prototype. it is anticipated that further development would entail the addition of any number of panes—perhaps several dozen. the ease of developing a resource pane can vary greatly depending on the resource. for developerfriendly resources that offer a useful javascript object notation (json) api, it can take less than half an hour. for article databases, which vendors generally take great pains to “lock down,” the task can entail a two-day marathon involving trial-and-error http-request-token authentication and screen-scraping of complex invalid html. in some cases, vendor license agreements may prohibit this kind of use altogether. there is little we can do about this; clearly, one of multipac’s severest limitations is its lack of adeptness at searching these types of “closed” remote resources. n item view item view (figure 11) provides greater detail about an individual item, including a display of more metadata fields, an image, and a link to the item in its primary context, if available. it is expected that this view also would include holdings status information for opac resources, although this has not been implemented yet. the availability of various page features is dependent on values encoded in the item’s solr metadata record. for example, if an image url is available, it will be displayed; if not, it won’t. an effort was made to keep the view logic separate from the underlying resource to improve code and resource maintainability. the page template itself does not contain any resource-dependent conditionals. n list view list view (figure 12), essentially a “favorites” or “cart” view, is so named because it is intended to duplicate the list feature of unlv libraries’ innovative millennium figure 9. the multipac browse view page information discovery insights gained from multipac | dolski 177 opac. the user can click a button in either results view or item view to add items to the list, which is stored in a cookie. although currently not feature-rich, it would be reasonable to expect the ability to send the list as an e-mail or text message, as well as other features. n metadata harvesting system for metadata to be imported into solr, it must first be harvested. in the harvesting process, a custom script checks source data and compares it with local data. it downloads new records, updates stale records, and deletes missing records. not all resources support the ability to easily check for changed records, meaning that the full record set must be downloaded and converted during every harvest. in most cases, this is not a problem; most of our resources (the library catalog excluded) can be fully dumped in a matter of a few seconds each. in a production environment, the harvest scripts would be run automatically every day or so. in practice, every resource is different, necessitating a different harvest script. the open archives initiative protocol for metadata harvesting (oai-pmh) is the protocol that first jumps to mind as being ideal for metadata harvesting, but most of our resources do not support it. ideally, we would modify as many of them as possible to be oai–compliant, but that would still leave many that are out of our hands. either way, a substantial number of custom harvest scripts would still be required. for demonstration purposes, the multipac prototype was seeded with sample data from a handful of diverse resources: 1. a set of 16,000 marc records from our library catalog, which we converted to marcxml and then to solr xml using xsl transformations 2. our locally built las vegas architects and buildings database, a mysql database containing more than 10,000 rows across 27 tables, which we queried and dumped into xml using a php script 3. our locally built special collections database, a smaller mysql database, which we dealt with the same way 4. our contentdm digital collections, which we downloaded via oai-pmh and transformed using another custom xsl stylesheet there are typically a variety of conversion options for each resource. because of time constraints, we simply chose what we expected would be the quickest route for each, and did not pay much attention to the quality of the conversion. n how multipac answers unlv libraries’ discovery questions multipac has essentially proven its capability of solving interface multiplication and fragmentation issues. figure 10. the multipac results view page 178 information technology and libraries | december 2009 by adding a layer of abstraction between resource and patron, it enables us to reference abstract resources instead of their specific implementations—for example, “the library catalog” instead of “the innopac catalog.” this creates flexibility gains with regard to resource provision and deployment. this kind of “pervasive decoupling” can carry with it a number of advantages. first, it can allow us to provide custom-developed services that vendors cannot or do not offer. second, it can prevent service interruptions caused by maintenance, upgrades, or replacement of individual back-end resources. third, by making us less dependent on specific implementations of vendor products—in other words, reducing vendor “lock-in”—it can potentially give us leverage in vendor contract negotiations. because of the breadth of information we offer from our website gateway, we as a library are particularly sensitive about the continued availability of access to our resources at stable urls. when resources are not persistent, patrons and staff need to be retrained, expectations need to be adjusted, and hyperlinks—scattered all over the place—need to be updated. by decoupling abstract resources from their implementations, multipac becomes, in effect, its own persistent uri system, unifying many library resources under one stable uri schema. in conjunction with a url rewriting system on the web server, a resource-based uri schema (figure 13) would be both powerful and desirable.8 n lessons learned in the development of multipac the lessons learned in the development of multipac fall into three main categories, listed here in order of importance. metadata quality considerations quality metadata—characterized by unified schemas; useful crosswalking; and consistent, thorough description—facilitates finding and gathering. in practice, a surrogate record is as important as the resource it describes. below a certain quality threshold, its accompanying resource may never be found, in which case it may as well not exist. surrogate record quality influences relevance ranking and can mean the difference between the most relevant result appearing on page 1 or page 50 (relevance, of course, being a somewhat disputed term). solr and similar systems will search all surrogates, including those that are of poor quality, but the resulting relevancy ranking will be that much less meaningful. figure 13. example of an implementation-based vs. resource-based uri implementation-based http://www.library.unlv.edu/arch/archdb2/index.php/projects/view/1509 resource-based (hypothetical) http://www.library.unlv.edu/item/483742 figure 11. the multipac item view page figure 12. the multipac list view page information discovery insights gained from multipac | dolski 179 metadata quality can be evaluated on several levels, from extremely specific to extremely broad (figure 14). that which may appear to be adequate at one level may fail at a higher level. using this figure as an example, multipac requires strong adherence to level 5, whereas most of our metadata fails to reach level 4. a “level 4 failure” is illustrated in table 3, which compares sample metadata records from four different multipac resources. empty cells are not necessarily “bad”— not all metadata elements apply to all resources—but this type of inconsistency multiplies as the number of resources grows, which can have negative implications for retrieval. suggestions for improving metadata quality the results from the multipac project suggest that metadata rules should be applied strictly and comprehensively according to library-wide standards that, at our libraries, have yet to be enacted. surrogate records must be treated as must-have (rather than nice-to-have) features of all resources. resources that are not yet described in a system that supports searchable surrogate records should be transitioned to one that does; for example, html webpages should be transitioned to a content management system with metadata ascription and searchability features (at unlv, this is planned). however, it is not enough for resources to have high-quality metadata if not all schemas are in sync. there exist a number of resources in our library that are well-described but whose schemas do not mesh well with other resources. different formats are used; different descriptive elements figure 14. example scopes of metadata application and evaluation, from broad (top) to specific

everyone involved with its creation and maintenance, and despite the high quality of many of our metadata records when examined in isolation, in the big picture, multipac has demonstrated—perhaps for the first time—how much work will be needed to upgrade our metadata for a discovery system. would the benefits make the effort worthwhile? would the effort be implementable and sustainable given the limitations of the present generation of “silo” systems? what kind of adjustments would need to be made to accommodate effective workflows, and what might those workflows look like? these questions still await answers. of note, all other open-source and vendor systems suffer from the same issues, which is a key reason that these types of systems are not yet ascendant in libraries.9 there is much promise in the ability of infrastructural standards like frbr, skos, rda, and the many other esoteric information acronyms to pave the way for the next generation of library discovery systems. organizational considerations electronic information has so far proved relatively elusive to manage; some of it is ephemeral in existence, most of it is constantly changing, and all of it is from diverse sources. attempts to deal with electronic resources—representing them using catalog surrogate records, streamlining website portals, farming out the problem to vendors—have not been as successful as they have needed to be and suffer from a number of inherent limitations. multipac would constitute a major change in library resource provision. our library, like many, is for the most part organized around a core 1970s–80s ils–support model that is not well adapted to a modern unified discovery environment. next-generation discovery is trending away from assembly-line-style acquisition and processing of primarily physical resources and toward agglomerating interspersed networked and physical resource clouds from onand offsite.10 in this model, increasing responsibilities are placed on all content providers to ensure that their metadata conforms to site-wide protocols that, at our library, have yet to be developed. n conclusion in deciding how to best deal with discovery issues, we found that a traditional product matrix comparison does not address the entire scope of the problem, which is that some of the discoverability inadequacies in our libraries are caused by factors that cannot be purchased. sound metadata is essential for proper functioning of a unified discovery system, and descriptive uniformity must be ensured on multiple levels, from the element level to the institution level. technical facilitators of improved discoverability already exist; the responsibility falls on us to adapt to the demands of future discovery systems. the specific discovery tool itself is only a facilitator, the specific implementation of which is likely to change over time. what will not change are library-wide metadata quality issues that will serve any tool we happen to deploy. the multipac project brought to light important library-wide discoverability issues that may not have been as obvious before, exposing a number of limitations in our existing metadata as well as giving us a glimpse of what it might take to improve our metadata to accommodate a next-generation discovery system, in whatever form that might take. references 1. unlv

manzari and trinidad-christensen 163 this study describes the life cycle of a library web site created with a user-centered design process to serve a graduate school of library and information science (lis). findings based on a heuristic evaluation and usability study were applied in an iterative redesign of the site to better serve the needs of this special academic library population. recommendations for design of web-based services for library patrons from lis programs are discussed, as well as implications for web sites for special libraries within larger academic library settings. u ser-centered design principles were applied to the creation of a web site for the library and information science (lis) library at the c. w. post campus of long island university. this web site was designed for use by master’s degree and doctoral students in the palmer school of library and information science. the prototype was subjected to a usability study consisting of a heuristic evaluation and usability testing. the results were employed in an iterative redesign of the web site to better accommodate users’ needs. this was the first usability study of a web site at the c. w. post library. human-computer interaction, the study of the interaction of human performance with computers, imposes a rigorous methodology on the process of user-interface design. more than an intuitive determination of userfriendliness, a successful interactive product is developed by careful design, testing, and redesign based on the testing outcomes. testing the product several times as it is being developed, or iterative testing, allows the users’ needs to be incorporated into the design. the interface should be designed for a specific community of users and set of tasks to be accomplished, with the goal of creating a consistent, usable product. the lis library had a web site that was simply a description of the collection and did not provide access to online specialized resources. a new web site was designed for the lis library by the incoming lis librarian who made a determination of what content might be useful for lis students and faculty. the goal was to have such content readily accessible in a web site separate from the main library web site. the web site for the lis library includes: ฀ access to all online databases and journals related to lis; ฀ a general overview of the lis library and its resources as well as contact information, hours, and staff; ฀ a list of all print and online lis library journal subscriptions, grouped by both title and subject, with links to access the online journals; ฀ links to other web sites in the lis field; ฀ links to other university web pages, including the main library’s home page, library catalog, and instructions for remote database access, as well as to the lis school web site; ฀ a link to jake (jointly administered knowledge environment), a project by yale university that allows users to search for periodical titles within online databases, since the library did not have this type of access through its own software. this information was arranged in four top-level pages with sublevels. design considerations included making the site both easy to learn and efficient once users were familiar with it. since classes are taught at four locations in the metropolitan area, the site needed to be flexible enough to serve students at the c. w. post campus library as well as remotely. the layout of the information was designed to make the web site uncluttered and attractive. different color schemes were tried and informally polled among users. a version with white text on black background prompted strong likes or dislikes when shown to users. although this combination is easy to read, it was rejected because of the strong negative reactions from several users. photographs of the lis library and students were included. the pages were designed with a menu on the left side; fly-out menus were used to access submenus. where main library pages already existed for information to be included in the lis web site, such as lis hours and staff, links to those pages were made instead of re-creating the information in the lis web site. an attempt was made to render the site accessible to users with disabilities, and pages were made compliant with the world wide web consortium (w3c) by using their html validator and their cascading style sheet validator.1 ฀ literature review usability is a term with many definitions, varying by field.2 the fields of industrial engineering, product

information technology and libraries | september 2006 as a commitment to users. dumas and reddish explain it simply: “usability means that the people who use the product can do so quickly and easily to accomplish their own tasks.”3 user-centered design incorporates usability principles into product design and places the focus on the user during project development. gould and lewis cite three principles of user-centered design: an early focus on users and tasks, empirical measurement of product usage, and iterative design to include user input into product design and modification.4 jakob nielsen, an often-cited usability engineering specialist, emphasizes that for increased functionality, engineering usability principles should apply to web design, which should be treated as a software development project. he advocates incorporating user evaluation into the design process first through a heuristic evaluation, followed by usability testing with a redesign of the product after each phase of evaluation.5 usability principles have been applied to library web-site design; however, library web-site usability studies often do not include the additional heuristic evaluation recommended by nielsen.6 in addition to usability, consideration should also be given during the design process to making the web site accessible to people with disabilities. federal agencies are now required by the rehabilitation act to make their web sites accessible to the disabled. section 508 part 1194.22 of the act enumerates sixteen rules for internet applications to help ensure web-site access for people with various disabilities.7 similarly, the web accessibility initiative hosted by the w3c works to ensure that accessibility practices are considered in web-site design. they developed the web content accessibility guidelines for making web sites accessible to people with disabilities.8 although articles have been written about usability testing of academic library web sites, very little has been written about usability testing of special-collection web sites for distinct user populations within larger academic settings.9 ฀ heuristic evaluation methodology heuristic evaluation is a usability engineering method in which a small set of expert evaluators examine a user interface for design problems by judging its compliance with a set of recognized usability principles or heuristics. nielsen developed a set of ten widely adopted usability heuristics (see sidebar). after studying the use of individual evaluators as well as groups of varying sizes, nielsen and molich recommend using three to five evaluators for a heuristic evaluation.10 the use of multiple experts will catch more flaws than a single expert, but using more than five experts does not produce greater results. in comparisons of heuristic evaluation and usability testing, the heuristic evaluation uncovered more of the minor problems while usability testing uncovered more major, global problems.11 since each method tends to uncover different usability problems, it is recommended that both methods be used complementarily, particularly with an iterative design change between the heuristic evaluation and the usability testing. for the heuristic evaluation, four people were approached from the palmer lis school faculty and ph.d. program with expertise in web-site design and humancomputer interaction. three agreed to participate. they were asked to familiarize themselves with the web site and evaluate it according to nielsen’s ten heuristics, which were provided to them. ฀ heuristic evaluation results the evaluators were all in agreement that the language was appropriate for lis students. one evaluator said if new students were not familiar with some of the terms they soon would be. another thought jake, the tool to access full text, might not be clear to students at first, but the lis web-site explanation was fine the way it was. they were also in agreement that the web site was well designed. comments included: “the purpose and description of each page is short and to the point, and there is a good, clean, viewable page for the users”; “the site was well designed and not over designed”; “very clear and user friendly”; “excellent example of limiting unnecessary irrelevant information.” the only page to receive a “poor layout” comment was the lengthy subject list of journals, though no suggestions for improvement were made. concern was expressed about links to other web sites on campus. one evaluator thought new students might be confused about the relationship between long island university, c. w. post, and the palmer school. two evaluators thought links to the main library’s web site could cause confusion because of the different design and layout. a preference for the design of the lis library web site over the main library and palmer school web sites was expressed. to eliminate some confusion, the menu options for other campus web sites were dropped down to a separate menu right below the menu of lis web pages. for additional clarity, some of the main library pages were re-created in the style of the lis pages instead of linking to the original page. the evaluators made several concrete suggestions for menu changes, which were included in the redesign. it was suggested that several menu options were unclear and needed clarification, so additional text was added for clarity at the expense of brevity. long island university’s online catalog is named liucat and was listed that way on the menu. new students might not be familiar with this name, so the menu label was changed to liucat (library catalog). user-centered design of a web site | manzari and trinidad-christensen 165 for the link to jake, a description, find periodicals in online databases, was added for clarification. it was also suggested that the link to the main library web page for all databases could cause confusion since the layout and design of that page is different. the wording was changed to all databases (located in the c. w. post library web site). menu options were originally arranged in order of anticipated use (see figure 1). thus, the order of menu options from the lis home page was databases, journals, library catalog, other web sites, palmer school, and main library. evaluators suggested that putting the option for lis home page first would give users an easy “emergency exit” to return to the home page if they were lost. the original menu options also varied from page to page. for example, menu options on the database page referred only to pages that users might need while doing database searches. at the suggestion of evaluators, the menu options were changed to be consistent on every page (see figure 2). a redesign based on these results was completed and posted to the internet for public use (see figure 3). ฀ usability testing methodology usability testing is an empirical method for improving design. test subjects are gathered from the population who will use the product and are asked to perform real tasks using the prototype while their performance and reactions to the product are observed and recorded by an interviewer. this observation and recording of behavior distinguishes usability testing from focus groups. observation allows the tester to see when and where users become frustrated or confused. the goal is to jakob nielsen’s usability heuristics visibility of system status—the system should always keep users informed about what is going on, through appropriate feedback within reasonable time. match between system and the real world— the system should speak the user’s language, with words, phrases, and concepts familiar to the user rather than system-oriented terms. follow real-world conventions, making information appear in a natural and logical order. user control and freedom—users often choose system functions by mistake and will need a clearly marked “emergency exit” to leave the unwanted state without having to go through an extended dialogue. support undo and redo. consistency and standards—users should not have to wonder whether different words, situations, or actions mean the same thing. follow platform conventions. error prevention—even better than good error messages is a careful design that prevents problems from occurring in the first place. recognition rather than recall—make objects, actions, and options visible. the user should not have to remember information from one part of the dialogue to another. instructions for use of the system should be visible or easily retrievable whenever appropriate. flexibility and efficiency of use—accelerators, unseen by the novice user, may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. allow users to tailor frequent actions. aesthetic and minimalist design—dialogues should not contain information that is irrelevant or rarely needed. every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility. help users recognize, diagnose, and recover from errors—error messages should be expressed in plain language (no codes), precisely indicate the problems, and constructively suggest a solution. help and documentation—even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. any such information would be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.12 figure 1. original menu figure 2. revised menu 166 information technology and libraries | september 2006 uncover usability problems with the product, not to test the participants themselves. the data gathered are then analyzed to recommend changes to fix usability problems. in addition to recording empirical data such as number of errors made or time taken to complete tasks, active intervention allows the interviewer to question participants about reasons for their actions as well as about their opinions regarding the product. in fact, subjects are asked to verbalize their thought processes as they complete the tasks using the interface. test subjects are usually interviewed individually and are all given the same pretest briefing from a script with a list of instructions followed by tasks representing actual use. test subjects are also asked questions about their likes and dislikes. in most situations, payment or other incentives are offered to help recruit subjects. four or five subjects will reveal 80 percent of usability problems.13 messages were sent to students via the palmer school’s mailing lists requesting volunteers. a ten-dollar gift certificate to a bookstore was offered as an inducement to recruitment. input was desired from both master’s degree and doctoral students. the first nine volunteers to respond—all master’s degree students—were accepted. this group included students from both the main and satellite campuses. no ph.d. students volunteered to participate at first, citing busy schedules, but eventually a doctoral student was recruited. testing was conducted in computer labs at the library, at the palmer school, and at the manhattan satellite campus. demographic information was gathered regarding users’ gender, age range, university status, familiarity with computers, with the internet, and with the lis library, as well as the type of internet connection and browser usually used. the subjects were given eight tasks to complete using the web site. the tasks reflected both the type of assignment a student might receive in class and the type of information they might seek on the lis web site on their own. the questions were designed to test usability of different parts of the web site. ฀ ฀usability testing results the first task tested the print journals page and asked if the lis library subscribes to a specific journal and whether it is refereed. (the web site uses an asterisk next to a journal title to indicate that it is refereed.) all subjects were able to easily find that the lis library does hold the journal title. although it was not initially obvious that the asterisk was a notation indicating that the journal was refereed, most of the subjects eventually found the explanatory note. many of the subjects did not know what a refereed journal was, and some asked if a definition could be provided on the site. for the second task, subjects needed to use jake to find the full text of an article. none of the students were familiar with jake but were able to use the lis web site to gain an understanding of its purpose and to access it. the third task asked subjects to find a library association that required using the other web sites page. all subjects demonstrated an understanding of how to use this page and found the information. the fourth task tested the full-text databases page. only one subject actually used this page to complete the task. the rest used the all databases link to the main library’s database list. that link appears above the link to full-text databases and most subjects chose that link without looking at the next menu option. several subfigure 3. final home page user-centered design of a web site | manzari and trinidad-christensen 167 jects became confused when they were taken to the main library’s page, just as the evaluators had predicted. even though wording was added warning users that they were leaving the lis web site, most subjects did not read it and wondered why the page layout changed and was not as clear. they also had trouble navigating back to the lis web site from the main library web site. the fifth task tested the journals by subject page. this task took longer for most of the subjects to answer, but all were able to use the page successfully to find a journal on a given subject. the sixth task required using the lis home page, and everyone easily used it to find the operating hours. the seventh task required subjects to find an online journal title that could be accessed from the electronic journals page. all subjects navigated this page easily. the final task asked subjects to find a book review. most subjects did not look at the page for library and information sciences databases to access the books in print database, saying they did not think it would be included there. instead, they used the link to the main library’s database page. one subject was not able to complete this task. problems primarily occurred during testing when subjects left the lis page to use a non-library science database located on the main web site. subjects had problems getting back to the lis site from the main library site. while performing tasks, some subjects would scroll up and down long lists instead of using the toolbars provided to bring the user to an exact location on the page. some preferred using the back button instead of using the lis web-site menu to navigate. these seemed to be individual styles of using the web and not any usability problem with the site. several people consistently used the menu to return to the lis home page before starting each new task, even though they could have navigated directly to the page they needed, making a return to the home page unnecessary. this validated the recommendation from the heuristic study that the link to the home page always be the first menu option to give users a comfortable safety valve when they get lost. the final questions asked subjects for their opinions on what they did and did not like about the web site, as well as any suggestions for improving the site. all subjects responded that they liked the layout of the pages, calling them uncluttered, clean, attractive, and logical. there were very few suggestions for improving the site. one person asked that contact information be included on the menu options in addition to its location right below the menu on the lis home page. another participant suggested adding class syllabi to the web site each semester, listing required texts along with a link to an online bookstore. some of the novice users asked for explanations of unfamiliar terms such as “refereed journals.” a participant suggested including a search engine instead of using links to navigate the site. this was considered during the initial site design but was not included since the site did not have a large number of pages. however, a search engine may be worth including. the one doctoral student had previously only used the main library’s web page to access databases. originally, he said he did not see the advantage of a site devoted to information science sources for doctoral candidates, since that program is more multidisciplinary. however, after completing the usability study, the student concluded that the lis web site was useful. he suggested that it should be publicized more to doctoral candidates and that it be more prominently highlighted on the main library web site. though the questions asked were about the lis web site, several subjects complained about the layout of the main library web site and suggested that it have better linking to the lis web site to enable it to be accessed more easily. ฀ conclusions iterative testing and user-centered design resulted in a product that testing revealed to be easy to learn and efficient to use, and about which subjects expressed satisfaction. based on findings that some students had not even been aware of the existence of the lis web site, greater emphasis is now given to the web site and its features during new student orientations. the biggest problem users had was navigating from the web pages of the main library back to the lis site. it was suggested that the lis site be highlighted more prominently on the main library web site. some users were confused by the different layouts between the sites, but no one expressed a preference for the design used by the main library web site. despite this confusion, subjects overwhelmingly expressed positive feedback about having a specialized library site serving their specific needs. issues regarding web-site design can be problematic for smaller specialized libraries within larger institutions. in this case, some of the problems navigating between the sites could be resolved by changes to the main library site. the design of the lis web site was preferred over the main campus web site by both the heuristic evaluators and the students in the usability test. however, designers of a main library web site might not be receptive to suggestions from a specialized or branch library. although consistency in design would eliminate confusion, requiring the specialcollection’s web site to follow a design set by the main institution could be a loss for users. in this instance, the main site was designed without user input, whereas the specialized library serving a smaller population was able to be more dynamic and responsive to its users. finding an appropriate balance for a site used by students new to the field as well as advanced students is 168 information technology and libraries | september 2006 a challenge. although the students in the study were all experienced computer and web users, their familiarity with basic library concepts varied greatly. a few novice users expressed some confusion as to the difference between journals and index databases. there actually was a description of each of these sources on the site but it was not read. (the subjects barely read any of the site’s text, so it can be difficult to make some points clearer when users want to navigate quickly without reading instructions. several subjects who did not bother to read text on the site still suggested having more notes to explain unfamiliar terms. however, if the site becomes too overloaded with explanations of library concepts, it could become annoying for more advanced users.) a separate page with a glossary is a possibility—based on the study, however, it will probably not be read. another possibility is a handout for students that could have more text for new users without cluttering the web site. having such a handout would also serve to publicize the site. there was some concern prior to the study that offering more advanced features, such as providing access to jake or indicating which journals are refereed, might be off-putting for new students; therefore, test questions were designed to gauge reactions to these features. most students in the study did express some intimidation at not being familiar with these concepts. however, all the subjects eventually figured out how to use jake and, once they tried it, thought it was a good idea to include it. even new students who had the most difficulty were still able to navigate and learn from the site to be able to use it efficiently. an online survey was added to the final design to allow continuous user input. the site consistently receives positive feedback through these surveys. it was planned that responses could be used to continually assess the site and ensure that it is kept responsive and up-to-date; however specific suggestions have not yet been forthcoming. how valuable was usability testing to the web-site design? several good suggestions were made and implemented, and the process confirmed that the site was well designed. it provided some insight into how subjects used the web site that had not been anticipated by the designers. since usability studies are fairly easy and inexpensive to conduct, it is probably a step worth taking during the web-site design process even if it results in only minor changes to the design. references

extension tools have emerged in the past decade aimed at helping information seekers find open versions of scholarly articles when they hit a paywall, including open access button, lazy scholar, kopernio, and unpaywall. while librarians have written numerous reviews of these products, no one has yet conducted a usability study on these tools. this article details a usability study involving six undergraduate students and six faculty at a large public research university in the united states. participants were tasked with installing each of the four tools as well as trying them out on three test articles. both students and faculty tended to favor simple, clean design elements and straightforward functionality that enabled them to use the tools with limited instruction. participants familiar with other browser extensions gravitated towards tools like open access button, whereas those less experienced with other extensions preferred tools that load automatically, such as unpaywall. introduction while the open access (oa) movement seeks to make scholarly output freely accessible to a wide number of people, finding the oa versions of scholarly articles can be challenging. in recent years, several tools have emerged to help individuals retrieve an oa copy of articles when they hit a paywall. some of the most familiar of these—lazy scholar, open access button, unpaywall, and kopernio—are all free browser extensions. however, poor user experience can hamper even the adoption of free tools. usability studies, particularly of academic websites and search tools, are prevalent in the literature, but as of yet no one has compared the user-friendliness of these extensions. how open access tools work all of the tools can be installed for free as a google chrome browser extension. all four tools also work in firefox. the idea is that when a user hits a paywall for an article, they can use that tool to search for an open version. each works slightly differently: open access button (https://openaccessbutton.org/)—the oa icon will appear to the right of the browser’s search bar (see figure 1). when a user clicks it, a new page will open that is either the open version of the article if one is found or a message saying it was not able to find an open version. the user is then given the option to write an email to the author asking that it be made open. mailto:eazadbakht@unr.edu mailto:teresas@unr.edu https://openaccessbutton.org/ information technology and libraries june 2020 at the click of a button | azadbakht and schultz 2 figure 1. the oab icon appears as an orange padlock in the browser's toolbar. lazy scholar (http://www.lazyscholar.org/)—a horizontal bar will appear at the top of the page for any scholarly article (see figure 2). along with other information, such as how many citations an article has and the ability to generate a citation for that article, pdf and/or file icons will appear in the middle of the bar if an open version is found. users can then click on any of the icons to be taken to that open version. if no open version is found, no icons will appear. there is no text message indicating nothing has been found. a browser button is also installed, and users can click it to make the bar disappear and reappear. figure 2. the lazy scholar toolbar appears just below the browser's search bar. kopernio (https://kopernio.com/)—a tab will appear in the bottom left corner of the screen for any scholarly article (see figure 3). if there is an open version, the tab will be dark green. if no article is found, the tab will be shorter and grey. if a user hovers over it, they will see a message indicating if an open version was found. when a user clicks on the dark green tab, kopernio automatically opens the article in its own viewer, called a locker, instead of the browser’s viewer. unlike the other three tools, users must register with kopernio and they can add their institution so kopernio can search to see if their institution has access to the article. http://www.lazyscholar.org/ https://kopernio.com/ information technology and libraries june 2020 at the click of a button | azadbakht and schultz 3 figure 3. the kopernio icon appears on the bottom left of the screen. unpaywall (https://unpaywall.org/)—a short tab will appear in the middle right of a screen for a scholarly article. when it has found an open version, the tab will turn bright green (see figure 4). when an open version has not been found, it will turn a light grey. clicking on the grey tab will also open a message indicating an open version could not be found. figure 4. unpaywall's green padlock icon appears halfway down on the right side of the screen. literature review the need for open access finding tools although oa helps take down financial barriers to accessing the scholarly literature, there is no one place to deposit content in order to make it oa. the registry of open access repositories, a database of both institutional and subject repositories, shows 4,725 repositories.1 no central database exists that searches every possible location for oa material, which means discovery of oa content remains difficult. willi hooper noted that “making repository content findable is a major challenge facing libraries.”2 nicholas et al. found in their study of international early-career researchers that most rely on google and google scholar to find scholarly articles and that one of their main goals is to find the full text as fast as possible.3 google scholar does include oa versions of articles, but this is not always readily obvious without clicking and trying each article version until they find an oa version. dhakal also notes that search engines do not always aggregate content in institutional repositories on a consistent basis.4 joe mcarthur, one of the founders of the open access button, said he decided to invent it after hitting paywalls after graduating.5 https://unpaywall.org/ information technology and libraries june 2020 at the click of a button | azadbakht and schultz 4 oaft reviews and other research most of the scholarly literature on oafts has focused on reviews of specific tools. unpaywall has received a number of positive reviews,6 and both open access button7 and kopernio8 have received several as well. dhakal has noted that unpaywall “helps take the guesswork out of accessing oa articles.”9 reviewers have generally found the tools easy to use, although some have included criticism. for instance, rodriguez found that open access button can result in odd error messages and false negatives (that is, not finding an open access version that actually does exist), although he liked the tool overall.10 little research has looked at how well the tools work and how usable they are, however. regier informally investigated why unpaywall and similar tools do not always find articles that are open and noted that one problem is likely that publishers of oa journals do not always upload their license information to crossref, one of the sites that unpaywall relies on.11 schultz et al. looked at how many oa versions the tools found in comparison to google scholar. none of the tools found as many as google scholar, although lazy scholar, unpaywall, and open access button all compared favorably to it, and each tool found at least some open versions that no other tool did.12 usability and other evaluation studies since the late 1990s, libraries have sought to improve the user experience of their websites and electronic resources. usability testing has since become a popular means of evaluating a library’s online presence with the input of its users. blummer’s 2007 literature review chronicles the first phase of this trend in a section of her article dedicated to early usability studies of academic library websites.13 many of these studies included both student and faculty participants and found that navigation issues needed to be resolved in order to maximize users’ ability to locate key information on the library websites being evaluated. some also discovered that users misunderstood library terminology and that providing better descriptive terms and text helped improve the user experience.14 more recent examples of library website usability studies include one from 2018 by guay, rudin, and reynolds and another published in 2019 by overduin. the former’s findings echoed that of earlier studies that a cluttered interface can mask important navigational elements and content, hindering use.15 overduin describes a think-aloud, task-based study of the california state university bakersfield walter w. stiern library that concluded it was important for libraries to consider the preferences of both new and returning users when redesigning their websites.16 while most of the literature involves usability studies of library websites, online catalogs, and discovery layers, librarians have also evaluated other academic products and tools. in 2015, imler, garcia, and clements investigated pop-up chat reference widgets, such as those available through springshare’s libchat software program.17 librarians at the penn state university interviewed thirty students across three campuses, asking them to interact with a chat widget. the vast majority of students did not find the pop-up widget annoying, and many agreed that they would be more likely to use chat reference if they encountered it on the website. in addition, the participants preferred to have at least a ten-second delay between the loading of the webpage and the appearance of the pop-up, with an average ideal time of about fourteen seconds.18 information technology and libraries june 2020 at the click of a button | azadbakht and schultz 5 haggerty and scott evaluated the usability of an academic library search box and its s pecialized search features through task-based interviews with twenty participants, most of whom were students.19 most of the study’s participants indicated a preference for a simplified search box, though some were reluctant at losing access to the specialized search tabs. at around the same time, beisler, bucy, and medaille conducted a primarily task-based usability study of three streaming video databases to determine how patrons were using them.20 the students showed a preference for intuitive interfaces, whereas the faculty were concerned with the videos’ metadata and descriptions as well as the accessibility and shareability of the content. the databases’ advanced features were used less successfully. the results suggest that vendors would benefit from making navigation simpler and terminology clearer while enhancing search functionality. methodology in keeping with usability testing best practices, this study involved twelve subjects total, six students and six faculty members at the university of nevada, reno (unr).21 the authors sought subjects from a diverse set of science and social science disciplines. recruitment efforts consisted of fliers and targeted emails, some sent directly by the authors to faculty members in their liaison areas and others distributed to students and faculty by liaison librarian colleagues. interested students were directed to a simple qualtrics form that asked them for their name, major, class standing, contact information, and whether they had ever used any of the four too ls before. the student participants each received a $15 amazon gift card. faculty did not receive any compensation. the study was approved by unr’s institutional review board (project number 1452303-2). faculty interviews took place in september 2019, and student interviews took place in november 2019. the usability testing took place in three private conference rooms within the main library on a university-owned laptop running microsoft windows 10 and the chrome browser. participants were asked if they were regular users of chrome, and all were to some degree, with several indicating that they use it exclusively. both authors were present at all of the tests, alternating who walked the participants through the various tasks and who took notes. the screencast-omatic screen capture software recorded both the participants’ audio and video as well as their movements on the computer screen. referring to a script, the authors asked the participants to install each browser extension and use them, in turn, to find three scholarly articles from journals not available to the unr community but recently requested through the libraries’ interlibrary loan service. the authors switched the order in which they had participants install the four tools. half of the participants started by installing open access button, followed by lazy scholar, unpaywall, and kopernio, whereas the other half installed them in reverse order, beginning with kopernio. the authors uninstalled the tools between usability tests. the three journal articles were selected with the assistance of unr libraries’ coordinator of course reserves and document delivery services. the study purposely included articles that the university did not have access to in order to ensure that none of the tools found “open versions” simply because of the libraries’ subscription. two were findable by all four oa finding tools and one was a “planned fail” that could not be retrieved by any of them, allowing the autho rs to witness how participants responded to this failure on the part of the tools. participants decided information technology and libraries june 2020 at the click of a button | azadbakht and schultz 6 how long they were willing to spend figuring out a particular tool or finding the full text of an article. if, after a certain point, they deemed an article unfindable or realized that, in another setting, they would have given up on a tool, they could tell the interviewer that they wished to move on to the next task. finally, the authors ended each interview by asking the participants to expand upon any stray observations, share any final thoughts, and name which of the tools, if any, they would consider using in the future. each of the two authors reviewed half of the recordings and any notes, documenting key, deidentified information in a shared google sheet. they kept track of how long it took participants to install each of the four oa finding tools and whether they succeeded in locating the three articles—or, in the case of the planned fail, whether they successfully determined it was inaccessible. they also noted any issues the participants experienced and any comments they made. the authors met and coded all the information they had gleaned from the 12 usability tests together. limitations this study included only 12 participants, all from the same institution. the authors know the faculty participants, as they recruited faculty directly from the disciplines with which they routinely work. moreover, these faculty are all considered early or mid-career. while this was intentional, as the authors wanted to focus on that sub-population of researchers, it may have had an effect on the faculty members’ impression of the tools. likewise, the participants’ comfort with technology, particularly their ability to learn new technology on-the-fly, and prior experience using other browser extensions or research productivity tools was not formally assessed prior to testing. these skills may have impacted how quickly participants were able to figure out a particular tool and how long they tried to find the full text of one of the articles before giving up. results installation all participants successfully installed each of the four tools, and most took around the same time to install each tool, with none taking more than 90 seconds to install. the longest installation, 84 seconds for kopernio, was connected to a technical issue that occurred during the installation. most participants seemed to have an easy time installing the tools, although some noted they found certain tools easier to download than others. for instance, faculty 1 noted that they thought lazy scholar was easier to install than open access button, and faculty 3 said they thought both open access button and unpaywall “were pretty smooth.” student 2 liked it when there was an obvious “install now”–type button, saying, “that’s pretty convenient.” when participants did struggle, it was usually with open access button and lazy scholar. participants did not always seem to realize right away which button on open access button’s website would download the tool. other times, participants were not sure if the tool had installed, not noting the new button on the chrome browser bar. for lazy scholar, one participant, student 4, noted it seemed to take more clicks to install it, and two participants received an error message, although they both were able to successfully install the tool on a second try. kopernio also information technology and libraries june 2020 at the click of a button | azadbakht and schultz 7 resulted in several error messages for one participant when creating an account, and the authors had to use one of their accounts to allow the participant to continue with the study. ability to use the tools when looking at whether participants were able to successfully use each tool on each of the three sample articles, we determined that participants were most successful using unpaywall. all participants successfully used the tool on article 1 and article 3. because article 2 was the planned fail in that no tool was able to locate it, participants who did not realize this and continued to try to use a tool to find it were deemed to have “failed” that particular task. by this measure, one faculty member failed on the second article while using unpaywall. lazy scholar and open access button each had a total of eight fails, with two participants—a faculty member and a student—failing on all three articles, and another student failing on the first two before successfully using the tool on the third article. kopernio had a total of ten fails, with two participants failing on all three articles, and two others failing on the first two. all four of these participants were faculty members. in some cases of failures, participants would either try to find instructions for the tools or try clicking around on the screen and then following various links to see if they could successfully use the tools. in other cases, participants gave a cursory search for the tool but stopped after a short period of time. article 2, the planned fail, also caused confusion for participants. for instance, one faculty participant seemed to think that open access button had a technical glitch and looked to the instructions to see if they could troubleshoot it. others never seemed certain if the tool was working incorrectly or if the article just was not available. another issue came with the article version that lazy scholar returned for article 3. unlike the other instances when the tool took users directly to the article file, in this case lazy scholar took participants to the record page for the article in a scholarly repository. participants could then click on a link for the full text, and it took several participants a few tries of clicking around on the page before finding the correct link. student 2 noted “i expected it to pull up the pdf like all the others did.” another student stopped at the record page, not realizing they could click one more link to get the full text, which was considered a fail. themes several themes emerged during usability testing. a major one was the design of the various extensions, encompassing their aesthetics and on-screen behavior. other themes include the usefulness of each tool’s instructions and additional features as well as how participants’ experience with other browser extensions shaped how their expectations of the four tools. design as with most usability studies, certain design choices determined how successful students and faculty were at finding the three test articles and how they felt about the experience. participants gravitated toward simple, clean designs and faltered or expressed displeasure whenever they encountered extension elements that appeared overloaded with information or details. several participants, for instance, thought that lazy scholar’s toolbar was clunky or too cluttered looking, information technology and libraries june 2020 at the click of a button | azadbakht and schultz 8 even when they successfully used it to find the test articles. there were too many options embedded in the toolbar, which caused confusion, and its small font also proved problematic for a majority of the students and faculty. conversely, several participants said that they appreciated unpaywall’s minimalism, and many turned to it first when instructed to use the four tools to find the three articles. “this one is the most obvious one,” faculty 1 stated. many also responded positively to open access button’s neat-looking icon and simplicity. kopernio’s design led to a mix of user experiences. while participants seemed to appreciate its clear-cut, dark green icon, some of its other features—the search box and the storage “locker”—created unnecessary clutter. throughout testing, participants also expressed mixed views of tools that featured an automatic pop-up as a means of indicating that a free version of an article was or was not available. lazy scholar, unpaywall, and kopernio all involve some version of this design choice. open access button behaves like other commonly used browser extensions, such as zotero, in that the extension remains inactive until clicked upon. the participants’ stated preferences did not always align with their behavior. some participants did not like that the pop-ups appeared without prompting and that the pop-up tools blocked parts of the computer screen. “i like things that go away,” explained faculty 3. faculty 6 noted that they preferred open access button because it did not load automatically and that it opened in a new, separate window. what’s mo re, those participants who had experience using other browser extensions were not expecting the pop -ups and first tried clicking on the tools’ icons embedded in the browser bar. this happened more often with lazy scholar and kopernio than it did with unpaywall, but all three experienced this. however, several who said that they found pop-ups “annoying” or “distracting” nevertheless were able to successfully use the tools to quickly find free versions of the test articles. this discrepancy was especially evident in the case of unpaywall, which almost everyone used successfully and with apparent ease. a tool’s placement on the screen was likewise one of the key aspects of the tools’ design that made it either easier or more difficult to use during usability testing. unpaywall’s tab sits on the middleright side of the computer screen, whereas kopernio’s green “k” tab appears toward the bottom of the screen. sometimes the icon would disappear entirely after a few seconds, reappearing only after the page had been reloaded. kopernio’s location was especially problematic because most participants are not accustomed to needing to scroll or look to the bottom of a webpage. moreover, needing to scroll is “not convenient,” explained student 3. this appeared related to at least some of the failures that participants had with the tool. kopernio’s design did improve somewhat midway through usability testing. the icon is now highlighted when the webpage first loads and stopped dropping to the bottom of the page. however, some participants still missed the icon on their initial use of kopernio. student 2 said afterward that “unpaywall is definitely easier to use, because its pop-up button stayed up.” lazy scholar’s toolbar also proved a stumbling block for several participants. some did not notice it at first whereas others were not sure where within the toolbar they needed to click to retrieve the article, even though this is indicated by a standard pdf or html icon. the use of color also impacted participants’ success with the tools, particularly unpaywall. unpaywall’s lock icon turns bright green when the tool has found an open version of the article information technology and libraries june 2020 at the click of a button | azadbakht and schultz 9 and grey when it has not. both faculty and students appreciated this simple status indicator. “i recognized the little green button,” said student 4. for users with color vision deficiency, however, this favorite feature could be problematic. users can click on the icon regardless of whether they can differentiate between the icon’s two settings or not, but some convenience is lost. the kopernio icon’s darker green is likewise an issue for those with some forms of color blindness. open access button’s and lazy scholar’s color choices garnered less comment. prior experience with browser extensions another aspect of the tools’ design that influenced how participants interacted with a particular tool and how intuitive they ultimately found it to use was their prior experience with other browser extensions. several participants indicated that they used other browser extensions in their everyday lives. specifically, this knowledge appeared to affect their success with open access button, which behaves like most browser extensions do in that it does not launch automatically. faculty 2 said that using open access button “felt the most natural,” and faculty 3 said, “most other browser extensions i’ve used, when you want it to do the thing, you click it.” some participants who had less experience with other browser extensions still managed to use open access button successfully, though it took them slightly longer to do so. however, a few participants failed to use the tool at all during testing, having given up when they could not determine how it worked. instructions participants expressed a desire for simple, straightforward instructions and were more likely to read instructions that seemed succinct and easy-to-follow. they were also more likely to try out a tool just after installing it if the tools’ instructions were clear and if the instructions provided an example they could use to see the tool in action. unpaywall’s instructions do this particularly well, as they consist of minimal text on a large image of how the tool works. open access button and kopernio both provided instructions and examples that helped mitigate some of the issues participants had with them. for example, those who tried out open access button’s example before attempting to find the test articles—or who referred back to the instructions when they encountered a problem—were more likely to use it successfully, even if their prior experience with traditionally designed browser extensions was limited. kopernio’s instructions highlight where the icon appears, which primed the participants to later look towards the bottom of the screen for it. although this did not prevent confusion when using kopernio (as noted previously), it did reduce it. lazy scholar’s instructions, on the other hand, are quite detailed and are written in a very small font. this combination intimidated the participants, many of whom chose to quickly move on to the next task. some scanned the instructions, but none read through them. additional features three of the four tools—lazy scholar, kopernio, and, to a limited extent, open access button— offer additional features, including a way to contact article authors, integration with citation management tools, article metrics, and file storage space. however, many participants did not take note of the tools’ ability to do things other than find open versions of scholarly articles, and their enthusiasm for these options varied. this is likely partly due to the focus of the usability tests on these tools’ core function. more of the students responded positively to the tools’ extra features than did the faculty. information technology and libraries june 2020 at the click of a button | azadbakht and schultz 10 lazy scholar’s and kopernio’s extra features received the most attention. two students responded positively to lazy scholar’s cite option (a mendeley integration) in particular. for student 5, it made lazy scholar stand out. participants also tried out kopernio’s google scholar-powered search box when they had trouble locating and using its pop-up tab. a few students indicated that they would consider using this feature again to find related articles. however, those participants who came across mentions of kopernio’s article storage tool, known as a “locker,” either expressed confusion over its purpose—“locker? what locker?” wondered faculty 5—or were simply not interested in learning more about it. others said they did not need storage space of this kind. “i don’t get the metaphor. my hard drive is my locker,” noted faculty 2. favorites when asked which, if any, of the tools they preferred and would consider using, eight of the participants said unpaywall, followed by seven who said open access button (see table 1). four said they liked lazy scholar, and two said they liked kopernio, although two participants said they specifically would not use kopernio, and two said the same of lazy scholar. it is important to note that many of the participants named multiple tools, suggesting that they saw the need to rely on more than just one tool. table 1. breakdown of preference for oa finding tool by faculty and students. participant group open access button unpaywall lazy scholar kopernio faculty 3 4 1 1 students 4 4 3 1 discussion keep it simple the results show that users most preferred simplicity, including the instructions for downloading and using the tools. for example, participants seemed to have the easiest time downloading and trying out unpaywall because of how large and obvious its download button was, as well as how minimal and large their instructions were. in comparison, participants also seemed to like lazy scholar’s large and easy-to-see download button but disliked the long instructions, which were in a smaller font. as most of them did look at the instructions for unpaywall, it is clear they do find instructions helpful, as long as they can be read and understood in just a few seconds. this also seemed to be the reason why some participants struggled to find open access button’s icon. although the site does provide an instructional image similar to unpaywall’s, it is smaller and does not do as good of a job of pointing out the button’s location. some participants took a moment to look at the image but failed to notice what it was trying to highlight. likewise, participants, especially faculty, seemed to prefer the tools with a simple and clean design. the added features of lazy scholar were not worth the space it took up on the page. a few even remarked negatively on the size of the kopernio pop-up tab, saying it blocked too much of the screen. although a few at first remarked negatively on the unpaywall tab, several said that by information technology and libraries june 2020 at the click of a button | azadbakht and schultz 11 the end of the study, the tab no longer bothered them and that its usefulness outweighed its obtrusiveness. do not assume prior experience most participants who figured out how to use open access button seemed to like it; however, several struggled with finding it to begin with. part of this might be because the other tools, all of which use a pop-up tab, might have conditioned them to look for something similar. however, several participants noted that they were not familiar with browser extensions, which likely affected their ability to find the tool in the browser bar. they would try clicking directly on the article homepage screen. providing clear and obvious instructions would likely help ameliorate this issue. extra features not always worthwhile overall, participants did not seem interested in the extra features, especially kopernio’s locker and open access button’s option to email the author. and for faculty, the additional features of lazy scholar, including citation information and similar articles, proved to be a negative. however, some students did seem interested in these features, meaning this tool might be better for those who are still new to information discovery. conclusion although participants’ reaction to certain design elements, such as pop-ups and the finding tools’ additional features, were mixed, most of them were able to use the four browser extensions successfully. the tools’ location on the computer screen and their similarity (or dissimilarity) to other browser extensions influenced success rates. likewise, clean, simple design elements and straightforward instructions enhanced participants’ experience with the four tools. even though more of the students and faculty said they preferred unpaywall and open access button, each of the four tools appealed to at least some of the participants. both students and faculty were excited to find out about these tools and some even expressed surprise that they are freely available. many seemed open to the idea of using more than one tool, which can be helpful given each extension’s distinctive approach to finding and retrieving articles. however, having them use four tools at once also appeared to create issues for at least some of the participants as they would confuse which tool was which. librarians and other oa advocates can use the information from this study to help guide potential users to the tools that best suit their individual preferences and comfort level with similar technologies. increased promotion will ramp up adoption of the tools by a more diverse pool of users, which will ultimately generate the feedback needed to make the extensions more intuitive overall. endnotes 1 registry of open repositories, “welcome to the registry of open access

extra features not always worthwhile conclusion endnotes 12 information technology and libraries | september 2008 mylibrary: a digital library framework and toolkit eric lease morgan this article describes a digital library framework and toolkit called mylibrary. at its heart, mylibrary is designed to create relationships between information resources and people. to this end, mylibrary is made up of essentially four parts: (1) information resources, (2) patrons, (3) librarians, and (4) a set of locally defined, institution-specific facet/term combinations interconnecting the first three. on another level, mylibrary is a set of object-oriented perl modules intended to read and write to a specifically shaped relational database. used in conjunction with other computer applications and tools, mylibrary provides a way to create and support digital library collections and services. librarians and developers can use mylibrary to create any number of digital library applications: full-text indexes to journal literature, a traditional library catalog complete with circulation, a database-driven website, an institutional repository, an image database, etc. the article describes each of these points in greater detail. n background and history the term “mylibrary” was coined by keith morgan, doris sigl, and myself in 1997 when we worked in the department of digital library initiatives at the north carolina state university libraries. at that time it denoted a personalizable/customizable user interface to sets of library collections and services. it was a reaction to the then-popular portal applications called my netscape, my yahoo!, and my dejanews.1 in that form, mylibrary was a monolithic turnkey application. librarians were expected to use the administrative interface to organize information resources into three distinct groups: databases, electronic texts, and library links (services). each item in each group was expected to be associated with one or more discipline terms. patrons were expected to come to the system, register, select a discipline, and use the databases, texts, and library links to do library research. patrons had three additional functions at their disposal. the first was the ability to add “personal” links—bookmarks to their favorite websites. second, they had the ability to select multiple disciplines and thus refine the number of resources associated with “their” page. finally, and to a small degree, patrons had the ability to change the graphic design of the page. because of these customizable features and its implementation at ncsu libraries, the system was officially called mylibrary@ncstate. mylibrary@ncstate was packaged and distributed as open-source software, a newly coined term at that time. it was subsequently downloaded and installed in roughly two dozen libraries across the world. some of these libraries used it in exactly the manner it was designed, and some of them are still accessible today.2 other libraries used parts and pieces of the system to build their own applications. for example, the openuniversity used only the underlying database structure.3 on the other hand, los alamos national laboratory used to mylibrary@ncstate concept and completely re-wrote the perl modules.4 more importantly, the concept of mylibrary—a userdriven, customizable interface to sets of library collections and services—became very popular. mylibrary-like applications sprang up all over the library landscape. these implementations did not use the perl modules and scripts written under the mylibrary@ncstate rubric, but they did organize content in an underlying database and allowed patrons to mix and match the content for their specific purposes.5 as a turnkey application, mylibrary@ncstate functioned correctly. it did not crash and it did not output invalid data. at the same time, mylibrary@ncstate did not fare very well when it came to usability tests. for example, gibbons describes how the usability of mylibrary was improved to meet the needs of course offerings.6 in another article, brantley describes how users had difficulty “understanding the discipline-specific nature” of mylibrary@ncstate.7 its installation process was nonstandard and therefore difficult to implement. as written, mylibrary@ncstate was difficult to extend and enhance, and thus it did not truly benefit from its open-source nature. data entry was tedious and for this reason its content was difficult to initialize and maintain. the idea of actively customizing a user interface was foreign to many users. people do not take an active role in customizing their user interfaces. they accept the defaults or unconsciously expect the user interface to adapt to their needs.8 for all these reasons, mylibrary@ncstate’s popularity lasted about five years, but for many of the reasons outlined previously, the concept of mylibrary still seems viable. the balance of this article describes two things: (1) how the current implementation of mylibrary has evolved beyond the turnkey nature of mylibrary@ncstate, and (2) how the “new and improved” mylibrary has been and can be used to create a number of digital library applications. eric lease morgan is head of the digital access and information architecture department, hesburgh libraries, university of notre dame, indiana. mylibrary: a digital library framework and toolkit | morgan 13 n mylibrary, relationships, and facet/term combinations more than anything else, mylibrary is intended to provide a framework for creating relationships between information resources and people. most of the time these information resources are the traditional things of libraries such as books, journals, indexes, catalogs, manuscripts, and photographs. the people of mylibrary are patrons and librarians. relationships can be drawn between information resources and people through the use of facet/term combinations—a locally defined and institution-specific controlled vocabulary. information resources and people can be described in similar fashions. resources, for example, are described with subjects. they are described according to their physical format and function. patrons and librarians focus much of their energies in specific subjects: “i am majoring in philosophy.” sometimes people focus their attention on specific formats: “i need a journal article on . . .” sometimes people are interested in particular functions: “i need a definition for . . .” people can belong to particular audiences and they might want to use audience-specific resources: “these resources are particularly useful for students in geog 203.” in our increasingly networked environment, it is just as important to create relationships between people as it is to create relationships between information resources and patrons. librarians are not seen as the only authority on data and information. the opinions of one’s peers play an important role too. users want to read reviews, rank items according to various weights, and make decisions based on the thoughts of people like them. through facet/term combinations applied to users, this is possible. moreover, since users do not visit libraries as often as they used to, librarians need to figure out ways of staying in touch with their populations. by applying facet/term combinations to librarians as well as users, the librarians can know who their users are and users can easily identify subject experts. intended for use as the framework for a controlled vocabulary, the facet/term combinations of mylibrary give the librarian and developer an opportunity to describe and relate the primary components of libraries—information resources and people. through these facet/term combinations, conceptual links can be created between information resources and users, between users and librarians, and between librarians and resources. after creating a set of facet/term combinations, the librarian and developer can address increasingly popular desires such as but not limited to: n as a librarian, this is the set of resources i curate . . . n because you are in this class, you might want to use . . . n here is a list of all the encyclopedias on the topic of . . . n here is a list of patrons who use the resources i curate . . . n here is a list of the full-text article indexes . . . n here is a list of articles on . . . n the library owns the following special collections . . . n these special collections can be used for this class . . . n other people in this class have also used . . . n other people like you have used . . . n recommended resources for this subject are . . . n resources for this subject are . . . n the subject-specific librarian is . . . to be able to address these issues, the librarian and the developer first create sets of facet/term combinations and then assign one or more of them to information resources, patrons, and/or librarians. after the assignments have been made, lists of relevant mylibrary objects (information resources or people) can be generated by specifying—“joining” in relational database parlance—facet/ term combinations held in common between the objects. for example, if many information resources, patrons, and librarians were classified using a subjects/astronomy facet/term combination, then the librarian and developer can create a list of astronomy-related resources for patrons, a list of astronomy-interested patrons for librarians, and list of astronomy-responsible librarians for patrons. n mylibrary facets and terms mylibrary facets are intended to be the headings for very broad categories. mylibrary terms are expected to denote examples of the facets. facet/term combinations are expected but not required to be defined for every mylibrary implementation. every librarian and developer who uses mylibrary is expected to define his or her own set of facet/term combinations. in the form of a simplified entity-relationship diagram, figure 1 illustrates how the relationships between information resources and people are modeled in mylibrary. an easy-to-understand facet might be formats denoting the physical manifestation of an information resource. terms associated with a formats facet might include books, manuscripts, journals, microforms, articles, maps, pictures, movies, or datasets. given just about any information resource, a formats facet/term combination can be assigned to it. for example, a library that owns the encyclopaedia britannica might “catalog” it with the 14 information technology and libraries | september 2008 formats/books facet/term combination: title—encyclopaedia britannica facet/term—formats/books another easy-to-understand facet might be called research tools, denoting things used to find data and information. example terms might include dictionaries, thesauri, manuals, journal indexes, library catalogs, internet indexes, encyclopedias, atlases, or almanacs. continuing with the example above, encyclopaedia britannica might have an additional facet/term combination assigned to it: title—encyclopaedia britannica facet/term—formats/books facet/term—research tools/encyclopedias an audience facet might be created to denote classes of users. in an academic library, possible terms might include freshman, sophomores, juniors, seniors, graduate students, instructors, faculty, and staff. using a different information resource—say, dissertation abstracts—we might come up with a different set of facet/term combinations: title—dissertation abstracts facet/term—research tools/bibliographic indexes facet/term—audiences/graduate students using mylibrary’s facet/term combinations, it is almost trivial to create an authorities list. an authors facet can be created to denote the creators of works. specific names can be used as terms. similarly, there might be a need or desire to include genre headings. consequently, the adventures of huckleberry finn might be described like this: title—the adventures of huckleberry finn facet/term—audiences/adolescents facet/term—authors/mark twain facet/term—formats/books facet/term—genre/coming of age stories facet/term—genre/novels n mylibrary objects facet/term combinations are used to describe and create relationships between mylibrary objects. these objects include information resources and people, and the people consist of users and librarians. the idea of facet/term combinations has been described above. this section describes the mylibrary objects—information resources and people—in greater detail. information resources information resources are the traditional informationcarrying “things” of a library. typically they include books, journals, articles, manuscripts, indexes, catalogs, finding aids, etc. in order to organize and increase access to these materials, libraries systematically describe collections using rigorous cataloging procedures. with the advent of ubiquitous computing and the internet, at least two things have happened regarding the “things of a library.” first, they are increasingly less bibliographic in nature. while the number of books, journals, and articles is certainly not decreasing, the number of conference presentations, simulations, images, sounds, movies, and data sets is multiplying at an astounding rate. second, because of this additional content, the traditional rigorous cataloging procedures of librarianship do not scale to the amount of work that needs to be done. dublin core metadata elements were created to address these problems. facet/term combinations form the foundation for creating simple but local controlled vocabularies. facet/term combinations plus dublin core metadata elements plus a number of other attributes brought along from mylibrary@ncstate for backwards compatibility are used to describe information resource objects in mylibrary. attributes a few things ought to be noted about some of the mylibrary attributes. first, many of the dublin core elements can be duplicated with facet/term combinations. the prime candidates are elements that can be expressed as database many-to-many relationships. the dublin core element called creator is an excellent example. any figure 1. simplified mylibrary entity-relationship diagram. facets have a one-to-many relationship with terms. terms have a manyto-many relationship with resources, patrons, and librarians. after defining sets of facet/term combinations, the mylibrary api allows librarians and developers to build interconnections between resources, patrons, and librarians. mylibrary: a digital library framework and toolkit | morgan 15 single information resource may have many creators, and any creator may be associated with many resources. librarians and developers who use mylibrary are able to place creator information in an attribute of a mylibrary resource object and/or in a facet/term combination. the former usage is similar to traditional library cataloging technique and consequently requires additional overhead for editing records. the application of facet/term combinations makes it much easier to maintain database integrity as well as create browsable lists. just like creators, subjects might be better implemented as facet/term combinations, and the mylibrary subject attribute might be used as a placeholder for keywords or non-controlled vocabulary terms. each mylibrary resource object might have multiple subjects. using the facet/term approach, this is no problem to implement. using the dublin core subject field approach, this is challenging, since the field is not repeatable. to circumvent this, librarians and developers are encouraged to delimit subject term values with predefined characters (such as “|”). upon indexing or display, the subject attribute can be parsed into multiple values. identifiers mylibrary resource objects possess three distinct types of identifiers, and each has it own explicit use. the first is the mylibrary resource identifier, which is a relational database key. it is non-assignable and non-editable by librarians or developers. it is an internal value used to maintain relational database integrity. the second type of mylibrary resource identifier is called the fkey, and it is used to denote a foreign key. this attribute is primarily intended to contain the value of an identifier from a remote information system like the 001 field of a marc record. a better example includes the harvesting of records from oai data repositories. each record in each oai repository has an internet-wide unique identifier. this value is not a url, but usually a combination of characters and numbers analogous to the 001 field of a marc record. each repository may also implement a concept called “sets,” and each record might belong to multiple sets. when harvesting from a repository, the librarian and developer can save the oai identifier as an fkey value, and when the same record from an alternative set is discovered, the associated resource object can be updated instead of duplicated. the third type of identifier are resource::location objects. they are primarily intended for but not limited to urls. unlike all of the other resource attributes, resource::location objects are intended to have many values because information resources have many locations. for example, a library might have a printed version of the adventures of huckleberry finn, and its location is denoted by a call number. a library might also have an electronic version, and its location is a url. an online bibliographic database might be located at a particular url, but its locally developed help text might be located at a different url. each resource::location object has three qualities: (1) a key, (2) a type, and (3) a value. the key is an internal relational database identifier. the type is an institution-defined value denoting the kind of location. examples might include primary url, help text url, call number, local file name, and isbn or issn. the value is an example of the type, and, in the case of dublin core elements, might very well be the identifier. using mylibrary resource::location objects, single information resources can be displayed and multiple locations can be associated with them. library services think creatively regarding the definition of resource objects. think library services as well as books, journals, and databases. libraries are about more than collections. they are also about services applied against those collections. libraries want to promote their services just as much as they want to promote access to bibliographic indexes, special collections, and the wealth of monographs. these services include bibliographic and information literacy sessions, circulation services (such as interlibrary loan, item recalls, renewals, or document delivery), library tours, one-on-one reference consultations, and online chats. each of these services has a title, a description, and probably a url where details can be read online. mylibrary resource objects provide a means to embody this information in a concise package. all that is missing are facet/term combinations to relate them to other information resources or people. consider an audience facet. putting things on reserve is something of interest to instructors. consider an audience term called instructors. assign an audience/instructors facet/term combination to instructions for putting things on reserve. things put on reserve are intended for use by students. again, consider assigning something like an audience/ students facet/term combination to instructions for using the reserve book room. people—patrons and librarians mylibrary includes two types of objects representing people: patrons and librarians. like information resource objects, librarian and patron objects are characterized using a number of attributes plus facet/term combinations. on one level, the patron attributes are simple and rudimentary only including things like first name, last name, username, password, e-mail address, url, and image. this type of information was explicitly designed to map to the foaf (friend of a friend) architecture in the hopes of future compatibility. patron objects also 16 information technology and libraries | september 2008 include attributes for things like last date visited and total number of visits. this information forms the basis for potential what’s new? functionality. the patron object also includes functionality to record personal links for bookmarking features. the mylibrary librarian object is even simpler than the patron object since it only includes attributes for name, e-mail address, and url. just like the mylibrary information resource objects, both the patron objects and the librarian objects can be mapped to facet/term combinations. just as mla bibliography might be “cataloged” using a subjects/ english literature facet/term combination, a patron or librarian object can be “cataloged” in the same way. once these sorts of relationships are established, recommendations can begin to take shape. once patrons start bookmarking and associating particular resources and services to their identity, the system can take the next step and address things such as “people like you also used . . . ” or “popular resources in this area are . . .” moreover, once facet/term combinations are associated with people, then relationships between people can be created and the system can answer statements such as “other people interested in this topic include . . .” or “the patrons who are interested in this subject are . . .” establishing facet/term combinations for people is not as difficult as it may seem at first. in an academic library, much of this information can be gleaned from human resources data or the institution’s registrar office. libraries probably already get this information in one shape or another to populate their integrated library system circulation module. at the very least, this information includes a first name, a last name, and a unique institution identifier (possibly a username). given this information, the librarian and developer could query the institution’s directory services to discover institutional department and/or major field of study. just as this information is loaded into the integrated library system to support borrowing, it can be loaded into a mylibrary instance. each department or major can then be mapped to facet/term combinations. privacy is a real issue with the inclusion of patron information in a mylibrary instance. it should be taken very seriously. the use of mylibrary does not assume the inclusion of patron information; it is more than possible to use mylibrary and not have it contain any information about people. on the other hand, without this information a library prevents itself from providing the sort of services increasingly expected by its patrons. a discussion of the professional ethics of providing personalized services to library users in a computer-networked environment is beyond the scope of this article. each library must weigh for itself the strengths, weaknesses, advantages, and threats of using information about patrons to provide individualized services. n combining mylibrary with other “toolboxes” as a framework or toolbox, mylibrary is intended to support only certain aspects of a digital library, namely, the collection of content, information about people, and a means of making relationships between them. mylibrary is not intended to be an “integrated library system.” it has no acquisitions module. it has no circulation module. it includes the only the most basic functionality for searching. instead, librarians and developers are expected to combine mylibrary with other tools to fulfill these functions. for example, acquisitions functionality can be implemented by harvesting oai content. by combining mylibrary with another set of perl modules called net::oai::harvester, librarians and developers can import oai-based content into a mylibrary instance.9 feed net::oai::harvester an oai root url, and it will systematically harvest remote metadata in any number of metadata formats. since dublin core metadata is required of all oai data repositories, and since mylibrary supports a one-to-one mapping to dublin core elements, it is trivial to create mylibrary resource objects based on each of the harvested records. appendix a illustrates a simple yet complete oai acquisitions application. it harvests journal article metadata from the directory of open access journals. just about any bibliographic metadata format can be mapped to dublin core. examples include marc, marcxml, mods, ead, and tei. to get content in these forms into a mylibrary instance, the librarian and developer need to write a program reading bibliographic data, parsing out the desired information, and saving it to mylibrary. considering marc data, the venerable perl module called marc::record could be used to read and parse the data.10 the other data formats are xmlbased, and a perl-based application supporting xstl or xpath could be used to read and parse the data. in all of these cases the content of the mylibrary instance should be considered brief and the fkey value might point to the original file on the local file system. such mylibrary resource objects are useful for syndication, search result displays, or browsable lists. if more detail is required, then the brief records can point to the full metadata through the fkey value. mylibrary is not intended to support search. that is because search is best supported not by a database but by an indexer.11 there are myriad indexers available. some of them include swish-e, kinosearch, zebra, and lucene.12 to search the content of a mylibrary instance, librarians and developers are expected to write reports against the instance and use them as the content for indexing. appendix b illustrates a rudimentary but complete promylibrary: a digital library framework and toolkit | morgan 17 gram creating a kinosearch index against a mylibrary instance. once the index is created, librarians and developers are expected to write interfaces to search the index. appendix c illustrates one searching technique: get a query as input, search the index, return a record’s id value, lookup the record in mylibrary, display. in summary, mylibrary first defines a number fundamental library objects (information resources, people, and a controlled vocabulary). it then supports a perl-based application programmer interface (api) for doing input/ output against these objects. the input can be garnered from any number of streams—manual data entry, tabdelimited text files, marc or xml files, oai, etc. the output can be xml files, rss or atom feeds, oai, html subject pages, e-mail messages, or pdf files. n production and demonstration applications a number of diverse applications have been created with mylibrary. some of them are production services. some of them are not fully developed and only exist to demonstrate the possibilities. this section briefly describes a number of them. alex catalogue of electronic text the alex catalogue of electronic text is a collection of just less than 14,000 public-domain documents from american literature, english literature, and western philosophy. much of the content comes from project gutenberg, but it also includes content from the defunct eris project of virginia tech and the internet wiretap archive. each mylibrary resource object includes as much dublin core data as possible. the description attribute of each mylibrary resources includes not an abstract of the electronic text, but an rdf/xml version of the original text. a report was written against the mylibrary instance that saves the rdf/xml to the local file system. these files were then indexed with an open-source indexer called zebra, and access to the index was provided through a web services–based protocol called sru (search/retrieve via url). consequently, the catalogue is full-text searchable as well as searchable via title, creator, and subject. the contents of the subject fields were computed by analyzing each document and extracting statistically significant words. the searchable interface supports a did you mean? service by comparing search terms to alternative spellings and a wordnet thesaurus. the catalogue’s title and creator browsable lists are static html files built by a script written against the underlying mylibrary instance. finally, links to all of the documents and their subjects have been uploaded to del.icio.us. to facilitate this, a script was written against the database extracting all the titles, their creators, and subjects (“tags”). these things were then sent to del.icio .us via a perl module implementing the del.icio.us api. article index the directory of open access journals includes an oai interface to its journal titles as well as some of its articles. the article index system harvested the article metadata and saved it to a mylibrary instance. along the way, journal titles and publishers were saved to underlying facet/term combinations and linked to each article. this enabled the creation of browsable lists via publisher and source. the content of the database was indexed using kinosearch and made accessible via a perl module written to implement sru. search results are displayed in a brief format. details are available via a simple asynchronous javascript and xml (ajax-y) link. appendixes a, b, and c illustrate the core of this application. catholic research resources alliance the catholic research resources alliance (crra) is a “portal” intended to highlight rare and unique materials of interest to catholic scholars. much of this content exists in archives. archives use an xml format called ead to describe their holdings. the crra provides a mechanism for ingesting these ead files, parsing out controlled vocabularies, populating facet/term combinations accordingly, full-text indexing the ead, and supporting a searchable/ browsable interface to the entire content via sru. the crra also supports ingesting marc records as well as getting its input from online data-entry forms. reports are written against the underlying mylibrary instance allowing the crra’s content to be accessible via oai. facebook a facebook application has been written against the mylibrary data of the hesburgh libraries university of notre dame’s database-driven website. after facebook users load the application into their profile, they are presented with a set of default recommended resources. the user then has the option to select a different set of resources based on subject terms presented in a pop-up menu. the resulting list of resources is then saved to the user’s profile pane, giving easy access to the pertinent databases and indexes of his or her selected subject. library catalog mylibrary has been used to create a demonstration library catalog. about 300,000 marc records were downloaded 18 information technology and libraries | september 2008 from the library of congress. a program was written that reads each marc record, crosswalks it to dublin core, and creates mylibrary resource objects accordingly. each marc record is saved as an individual file on the file system. the whole collection is indexed with kinosearch, and an sru interface provides access to the index. as search results are returned, the existence of isbn numbers is checked. if found, cover art and user reviews are retrieved and displayed from amazon. each record is displayed in a brief format, but links to a fully tagged format is available as well as marcxml and mods formats. each record is also associated with a “get it for me” link. once clicked, the item is essentially checked out to the user. each user then has a “bookshelf” link displaying the items they have borrowed. hesburgh libraries, university of notre dame’s database-driven website the hesburgh libraries’ database-driven website is probably the most extensive mylibrary application in existence, and its primary purpose is to support the majority of the libraries’ website. the system begins with the integrated library system where much (but not all) of the library’s website content has been cataloged using traditional methods. each item in the catalog destined for the website has been flagged with a local note denoting such. each item’s description has also been enhanced with facet/term combinations. on a nightly basis, all of the items destined for the website are exported from the catalog as marc records. on a nightly basis, another script reads these records and updates a mylibrary instance. reports are written against the instance creating subject pages, format pages, tool pages, etc., complete with descriptions, recommendations, and links to associated librarians. some information resources on the website are not deemed worthy of a record in the catalog. for these items, a manual data-entry form was created allowing bibliographers and subject specialist librarians to supplement the website’s content. these resources are seamlessly integrated into the website along with the resources from the catalog. to facilitate search, reports are written against the mylibrary instance and fed to swish-e. the resulting index is then supplemented with the content of static web pages to support search this site functionality. using this database-driven and mylibrary-based system, the content of the libraries’ website has many fewer broken links because the links are all centrally maintained. the site also sports a common look and feel, making it easy for users to know where they are located in the system. this process also eliminates the need for selectors and subject specialist librarians to know any html. they can focus on content and the system can focus on presentation. n future directions and conclusion the mylibrary modules work in the manner in which they were intended, and they continue to be distributed and supported as open-source software, but software is never complete. mylibrary is available from cpan (comprehensive perl archive network). it is supported by a website complete with voluminous documentation, sample applications, access to a cvs repository, blog commentaries, and a mailing list with about 150 subscribers.13 yet despite the support, use of mylibrary outside the university of notre dame has been underwhelming. i assume this is true because the number of perl programmers in libraries is shrinking as the number other programming languages (php, python, ruby, java, etc.) grows. the modularity of the system may also be a factor since most of the library profession can not write a computer program and therefore will have a difficult time understanding how to put mylibrary into practical use. the idea of facet/term combinations used to describe information resources as well as people may be off-putting. finally, because mylibrary requires an underlying database to operate, the normal perl installation process (perl makefile.pl; make; make test; make install) can only be done after a bit of pre-installation processing. this is possibly another impediment to adoption—the installation process is a bit unusual. despite these issues, mylibrary works very well for the university of notre dame, and a number of improvements are planned. first, the underlying database contains a table for user reviews, and a perl module needs to be written allowing input/output against these tables. similarly, mylibrary presently includes tables for keeping track of how often a particular resource is used and by whom, but there is no module to update the table. future work will enhance this statistics table and implement the statistics module. finally—and most importantly—work will be done to make it easy to do input/output against a mylibrary instance through a rest-ful (representational state transfer) interface. as defined by rest, this interface will exploit the four transfer methods of http (get, post, put, and delete) to retrieve, create, edit, and remove mylibrary objects from the underlying database. by exploiting rest-ful computing techniques, at least two things will be enabled. first, application programmers will be able to use their favorite computer language to maintain a mylibrary instance. there will be no need to know perl; rest is computer-language independent. second, through the use of rest-ful computing mylibrary content will be more easily syndicated. for example, the output of a rest-ful mylibrary interface could be manifested in many flavors of xml. atom comes to mind, but an rdf/xml representation may be mylibrary: a digital library framework and toolkit | morgan 19 more expressive. the output of a rest-ful interface to mylibrary could also be manifested as a json (javascript object notation) data structure, making it easier to integrate mylibrary content in ajax-y interfaces. as more and more library collections and services are manifested in a computer-networked environment, the need to provide these collections and services in new and different ways increases. mylibrary is an attempt to address this issue, and it has met with qualified success. acknowledgments an enormous debt of gratitude goes to rob fox of the hesburgh libraries, university of notre dame for writing the bulk of the mylibrary perl modules. rob and i sat down together for a couple days in 2003 to learn about object-oriented perl programing techniques from ed summers (now working at the library of congress). we then coupled that experience with the needs and desires of the libraries to articulate and design mylibrary as it is today. while i wrote bits and pieces of the modules and used them to write many applications, rob was the person who really got his hands dirty. references and notes 1. keith morgan and tripp reade, “pioneering portals: mylibrary@ncstate,” information technology and

process of normalization, relational databases store data unambiguously and efficiently. because relational databases store their information in tables, records, and fields, it is necessary to specify the tables, records, and fields when querying a database. this requires the user to know the structure of the database. moreover, standard relational databases do not support full-text searching nor relevance-ranked output. indexers excel at search. given a stream of documents, indexers parse tokens (words) and associate them with document identifiers. searches against indexes return document identifiers and provide the means to retrieve the documents without the necessary knowledge of the index’s structure. indexers are weak at data maintenance. in a welldesigned database, authority terms can be updated in a single location and reflected throughout the database. indexers do not support such functionality. databases and indexers are two sides of the same information retrieval coin. together they form the technological core of library automation. 20 information technology and libraries | september 2008 12. there are a growing number of open-source indexers available on the web,

providing mobile services. one hundred fifty-one libraries were chosen based on circulation, with at least one library or library system from each state, to explore the diverse services provided to mobile users across the united states. according to the data, mobile apps, mobile reference services, mobile library catalogs, and mobile printing are among public libraries’ most-frequently offered services, as determined by mobile visits, content analysis, and librarian survey responses. every library examined had at least one mobile website, mobile catalog, mobile app, or webpage adapted for a mobile device. following the covid-19 outbreak, services such as mobile renewal, subscriber database access, mobile reservations, and the ability to interact with a librarian were expanded to allow better communication with customers—all from the comfort and safety of their own homes. libraries are continually looking for innovative methods to assist their mobile customers as the world changes. introduction searching can be done on a computer, but it’s more likely to be done on a mobile device.1 according to data from the pew research center, about 96 percent of american adults own a cell phone.2 americans are connecting to the internet via their mobile devices in greater numbers than ever before. the pew report also states that 81 percent of americans have a smartphone.3 while direct usage is not measured in terms of how it relates to public libraries, the reality is that users are looking to connect with businesses and services through their mobile devices. while the covid virus’ ongoing spread has had a significant effect on various public services sectors around the world, libraries, especially in suburban areas, had to evolve and adapt to the changing environment. public libraries now offer more patron services. while many public libraries offered curbside services during covid-19 as a way to provide continuity of service, contactless services—services without having to speak with librarians directly—also became prevalent.4 these services cross geographical boundaries and reduce the risk of disease transmission from direct contact with other people. however, are there areas where libraries are lacking? are there areas where libraries can improve, especially as more and more people are relying on mobile services rather than in-person ones? this study examines current mobile services being offered in public libraries across the united states, how these offerings changed due to the pandemic, and what services libraries are looking to offer in the future. literature review several studies have explored mobile devices and their usage in a broader context. currently, it is estimated that 67 percent of the world’s population has mobile devices, with most of those devices being smartphones.5 in the united states alone, nearly 80 percent of the population owns a mailto:liuy1@southernct.edu mailto:sbojo32@gmail.com information technology and libraries march 2023 services to mobile users 2 liu and lewis smartphone.6 people across the world use mobile media to talk to one another, order food, and attend meetings and appointments. “mobile media—referring to devices, services, and content accessible on the go—has in a decade rapidly become a part of urban culture, and the habit of using a mobile device in public is only increasing.”7 once the covid-19 pandemic hit, use of mobile media was the easy way to connect as shelter-in-place orders were mandated across the country. even as many people are venturing out again, using mobile media for certain services is likely going to continue. the world is forever changed because of the pandemic, and organizations like libraries have sought new ways to connect with their patrons. status of library services provided in public libraries while a few research articles have addressed services provided to mobile users in libraries, none at the time of writing were focused explicitly on services for mobile users in public libraries in the united states. some studies focused on libraries overseas.8 others focused on what drives a library to provide services for mobile devices and what drives users to want to access their library through a mobile device.9 with time, the availability of mobile-friendly services has become critical to a library’s long-term viability. the ability to search a library’s catalog, for example, has aided a traditional library’s modern relevance. “the digital library on mobile devices has been a milestone in library industry development, leading to huge changes in knowledge carrying, spreading, acquiring, processing , and sharing of cloud computing and big data in online and offline forms.”10 users want data at their fingertips, whether it is an online order or a library catalog. “social sharing functions such as reading, borrowing, sharing, comment tracking, automatic retrieval, and new book recommendations on mobile devices such as mobile phones have become the popular trend of digital library development.”11 when evaluating mobile library websites and apps that libraries use to offer services, the literature appears to imply that a mobile version of a library website is more prevalent than a dedicated (or “native”) app. this is because of the development cost, the different mobile platforms (apple, android, etc.), and the maintenance required.12 instead of creating an app, it is often easier to optimize the library’s website for mobile devices through responsive design techniques. the challenge for accessing a library website on a mobile device is making sure the website has the same functionality as when viewed on a desktop computer. “today’s mobile users are no longer satisfied with simple mobile websites with only a small fraction of the information and features that are available on desktop websites. the small screen size of a mobile device may make performing certain tasks more tedious or cumbersome, but mobile users do expect to perform more and more tasks on their mobile devices.”13 lemire et al. performed a study of how mobile services have improved since 2010. while academic libraries were analyzed and surveyed, this information is helpful and relevant to the study of public libraries. mobile apps offered across various libraries while mobile apps and mobile webpages aren’t precisely the same (as proven by previous literature), the study public library mobile apps in scotland: views from the local authorities and the public sheds some insight on the use of mobile apps. it seems that many libraries do not have or are not interested in developing a mobile app (this coincides with the findings from lemire et al.’s study in the united states).14 however, when the public was surveyed, they did want more information technology and libraries march 2023 services to mobile users 3 liu and lewis remote services offered to mobile devices from their libraries. to increase the use of library services, apps should be considered.15 “by using an app instead of a mobile-enabled website, all the functionalities of smart technology can be incorporated to the library’s advantage. improved communication with patrons increases exposure to communities who otherwise would not use library services.”16 a similar study was done in malawi, where mobile services to libraries were analyzed. as we might expect, since malawi has a developing economy, it has fewer mobile services then the more mature economies of the us or scotland. the country recognizes the potential of using mobile devices to access library services. computer shortages are often a problem within libraries in developing countries, so by creating mobile services, users could access the library through their own mobile devices.17 studies have also found that it is important to know what users are looking for and to use that information when creating an app design. “perceived situation efficiency and perceived mobile library quality positively affect intention to use mobile library, demonstrating that both quality and situation efficiency are necessary to satisfy library users’ needs in mobile era.”18 the quality of the library app or mobile website is obviously important, but knowing what kind of services will be provided is also important. users are not going to turn to an app if it is not going to provide the information they need. this reported study proved that mobile users want to quickly obtain the information they want in the most effective way possible. library services for mobile users universities are often more likely offering mobile services than are small-town libraries. nearly all prestigious universities in the united states are already using mobile-friendly services, according to a study of one hundred university libraries.19 typically, the services for mobile users include “mobile sites, mobile apps, mobile opacs, mobile access to databases, text messaging services, qr codes, augmented reality, and e-books.”20 public libraries may not offer all these mobile services, such as augmented reality, but the majority provide access to a mobile opac or library catalog. guo, liu, and bielefield examined how urban public libraries provide services for and offer content to mobile users.21 their analysis explored what was being done in an urban setting to potentially help public libraries plan and create mobile services. they looked into literature dating back to 1991, when mobile data was just a thought in some forward-thinkers’ minds, as was the concept of what a “mobile device” entailed. the study used current research to group library services into two categories: “traditional library services modified to be available via mobile devices and services created for mobile devices.”22 to conduct their study, a list of 138 urban libraries in the united states was used based on the urban libraries council. all 138 were examined using the same criteria. a list of contents was created (components of mobile websites, components of mobile apps, mobile reference services, social media, mobile reservation services, mobile printing, apps or databases). the findings supported the hypothesis that services for mobile users have been in place in urban libraries in the united states. according to guo et al., 95 percent offer at least one type of service for mobile users.23 pope and others discussed sms or text messaging services to a mobile device. researchers also mention the my info quest project, which was trying to get more libraries on board with using text information technology and libraries march 2023 services to mobile users 4 liu and lewis messaging, one of the mobile services studied in this review.24 literature from the fields of information science and library science shows that in recent years, typical library services have been adapted to be accessible via a mobile device rather than a service being developed specifically for a mobile platform. research design a selection of two to five of the most-visited public libraries per state was chosen based on a statistic from the institute of museum and library services’ database of 9,247 public libraries (this number treats library systems as one).25 the libraries were chosen based on two criteria: libraries needed to be in states having a sizable number of public libraries and to have at least 3 million yearly in-person visitors. this resulted in a list of public libraries compiled to ensure that all notable libraries in the united states were covered in this study. the sample of 151 libraries’ state and population served, total circulation, total number of programs, total visits, and other associated data were entered into an excel spreadsheet for analysis. with a low of 168,661 and a high of 16,686,945, the average number of visitors per year (prior to the pandemic) to these libraries is 2,663,292. these libraries serve an average of 700,924 people, with a low of 8,542 and a high of 4,294,460. the dataset includes all branch libraries, with the largest system having 92 branches. mobile website/app visits, content analysis, and email surveys were among the study methodologies used. the mobile website examination was conducted through an android mobile phone device, using a specially designed codebook/spreadsheet to store and analyze data collected and verified from the library websites through 2021. the services offered were checked on each library’s website. email surveys were developed as a supplement to ensure data accuracy and additional input of the library’s mobile services from the librarians who work there. irb approval was granted (protocol #406)26 because human participants did not provide personal information and simply responded to email surveys. the first questionnaire was sent out to each library via google forms, either through direct email addresses or the library’s web form, from april 3 through april 7, 2021. the follow-up email survey was designed to act as a check for some possible limitations (such as being unable to access app features) and was sent on april 19–20, 2021. the data was verified again through the imls database in early 2022. the overarching question of what services libraries provided to users via their mobile devices was designed to delve into the mobile websites and/or apps provided by libraries, as well as the resources provided by the mobile websites or apps, reference services, reservation services, remote printing, and other services provided to mobile users. results and findings examining the use of a mobile device to deliver services by these most-visited public libraries reveals intriguing and novel findings in comparison to the use of desktop access for services available to users. the poll sought to find the following information: which mobile services the libraries now provide, what they intend to provide, and any feedback received on their mobile services. information technology and libraries march 2023 services to mobile users 5 liu and lewis all library websites are accessible via mobile devices every one of the 151 libraries analyzed had a mobile website. in certain situations, this was the library’s website optimized and tailor-made with responsive designs for a mobile device. in other cases, all that was provided was a version of the library’s website (but not optimized, so navigation was more difficult). in other cases, the library’s website was merged with the parent organization and simply provided basic library information. examples of these three conditions of the library mobile websites are shown in figure 1. figure 1. examples of different library websites. library services were made available to mobile devices primarily due to covid-19, as indicated by the responses of 60 (40%) of the 151 libraries to online questionnaires using google forms. though it is practically difficult to compare the services offered in 2019 to those offered during the covid-19 pandemic, 38 (63%) of respondents indicated that they had added mobile services in the last year (see fig. 2). information technology and libraries march 2023 services to mobile users 6 liu and lewis figure 2. mobile services added because of covid-19. what services were added, particularly since covid-19? chat features were the most popular response as a reference service and a means to connect. one example is the usage of discord, a chat program that allows users to communicate by voice, video, and text, as a virtual communication tool to provide reference services. nearly every library implemented curbside pickup. during the pandemic, virtual events and online reference services also became popular additions. book delivery was still one of the mobile services that libraries provided, either using “chomp delivery” (a local delivery service company used by one library in iowa) or the united states postal service (usps). while these “ship to patron” delivery approaches may not be a frequent practice, it was an inventive approach to getting library books into the hands of clients who were unable to leave their homes. see figure 3 for common services added during covid-19. over half of libraries provide dedicated apps for mobile devices though all libraries had a website, more than half had a specific library app dedicated for users with mobile devices. out of the 151 libraries analyzed, 52 percent (78) had at least one dedicated app built for the library or library system (see fig. 4). these apps could be downloaded from the google play store (android platform) or the apple store (ios platform). all but one of the 78 libraries allowed

and lewis services delivered through library mobile websites all 151 libraries had some form of mobile website. although each website provided a lot of the same information, there were significant variances (see fig. 5). the ability to log in to one’s account was available on the investigated websites. this allows customers to search the library catalog, place holds on books, and renew any books that were currently checked out. all the websites included basic contact information as well as information about the locations and hours of the libraries, and all libraries have an online public access catalog (opac) accessible through mobile devices. web-mediated services have been in place particularly since covid-19. nearly every library now offers services such as curbside pickup for books and other materials. library events are now almost exclusively offered virtually. over 98 percent of libraries have a calendar or other means of informing users about forthcoming virtual activities and events. some libraries are now making available re-opening plans, covid-19 protocols, and even covid-19 vaccine information. almost every library’s main webpage mentions modifications brought on by covid-19. as a result, certain library hours have altered, and services at all libraries have been impacted by covid-19. typically, getting a library card was a service that physically took place in the library. during covid-19, libraries had to learn to be flexible. over 94 percent of libraries offered the ability to get a library card or allowed patrons to register for an e-card so they could check out books. some of these libraries offered the option of printing the paperwork and necessary documentation to obtain a library card, but this paperwork did have to be dropped off at the library. however, many allowed their patrons to either extend the expiration date on a current library card or apply for a new one to be able to use the library’s virtual services. many libraries require a library card to access some of their services, such as databases. nearly all libraries offered a variety of databases or other apps (such as libby/overdrive or hoopla). a library card is needed to access all services. a couple of libraries even have their databases behind a login screen, so a user cannot even see the list of available databases until they have a library card and log in. all libraries in the sample had a social media presence. discrepancies on library websites were noted concerning new arrivals and recommendations. only about 55 percent of library websites listed new arrivals and about 52 percent listed recommendations. it is possible that this data is included within the library catalog (and only accessible once a user has logged in). out of all libraries analyzed, 43 libraries (28%) offered both recommendations and listed new arrivals. a smaller number, 31 libraries (21%) did not offer either of these. additional services seen on some of the library websites included the option to recommend a purchase to the library, how and if libraries were accepting donations, and a list of online class es being offered. some libraries offered services on finding a job or becoming a united states citizen. overall, the library websites provided a lot of valuable information to patrons. some were easier to navigate than others. the locations, hours, and contact information should be easy to find and access; however, on quite a few websites, these points of information are not easily accessed, since some libraries’ websites required logging in. still, with some searching and scrolling, a user could get to nearly all the basic information they might be looking for. information technology and libraries march 2023 services to mobile users 9 liu and lewis figure 5. percentage of libraries in study that offered services via the library’s mobile website. services delivered through library mobile apps while the primary function of a library’s dedicated app seemed to be accessing the catalog and requesting books, common services delivered through apps also include listings of events, such as webinars, found in 35 libraries (45%) that have an app; recent arrivals or recommendations, found in 33 libraries (42%); and ways to contact the library, in 13 libraries (17%). (see fig. 6 for the complete list of services.) all percentages are calculated based on the number of libraries that had a dedicated app that had that feature (78). gathering the information available on mobile apps was challenging as some apps require users to be affiliated with that library and log in with a library card. the information on what the app provides primarily came from the screenshots in the google play store (for the investigators’ android mobile devices) and the description on either the library’s website or within the play store. the apple app store applications available for library use are not disclosed in this study. as a result, the number of apps that offer additional services (such as locations/hours, events, etc.) may be higher than the percentages in figure 6. for example, the brooklyn public library app (seen in fig. 8) has many features that are not shown in the sample on the google play store. clicking on library info will provide additional details beyond library locations and hours, but also contact information and links to social media. this information is only displayed to affiliated library patrons who have downloaded and logged in to the app. 52% 56% 95% 98% 99% 100% 100% 100% 100% 100% 100% 0% 20% 40% 60% 80% 100% 120% recommendations recent arrivals get a library card/ecard virtual programs library database search social

apps are the most popular method of connecting with patrons, maintaining an app and ensuring that it works on all mobile platforms and devices can be challenging. while creating and making an app available through the google play or apple app stores may be an easy procedure for certain libraries, others are impeded by a lack of technical expertise. designing and maintaining an app takes too much time and money, as voiced from the study survey. an in-depth examination of the google play store reveals that variables influencing the makers of each library’s app include familiarity with the community serviced, the potential for options, staff training, and phone access (see fig. 7). however, the majority of apps (67%) were commercially made, and only 33 percent were self-developed. this results in apps that are unique to the library and the user’s needs, but also require dedicated it staff to maintain the app. 17% 17% 42% 45% 63% 99% 99% 99% 0 0.2 0.4 0.6 0.8 1 1.2 social media

11 liu and lewis figure 7. app developers, according to the google play store. one of the most popular software developers that provide libraries with scalable, effective mobile applications is solus uk ltd. out of the 78 apps analyzed, 24 percent used this developer. feedback from the study survey indicated that this app has strong capacity to expand or change according to user requirements, and its interface is user friendly and simple (see fig. 8). the app was obviously updated during the past year to allow for contactless holds pickup, a service that many libraries are offering so patrons do not have to come into the library to pick up their books or other materials. however, that interface is markedly different than others. both the chicago public library and the brooklyn public library have self-developed apps (see fig. 9). the functionality of these apps is like that of the st. paul public library, but the look is very different. other apps, developed by other companies, also have an entirely different presentation and notion, such as responding time and user interface. the main purpose is the same: allow the user to be able to view the catalog and be able to check their holds and current materials. 5% 6% 6% 8% 17% 24% 33% 0% 5% 10% 15% 20% 25% 30% 35% boopsie other bibliocommons capira communico solus uk ltd self-developed information technology and libraries

library to connect with patrons is through mobile reference services. even when the library is not open, many people seek help from the library reference desk. while calling the library is always an option, it is often not the most convenient one. while not all mobile reference services will work in this instance, some certainly will. an increasingly common example is the use of chatbots to offer such services. out of the 151 libraries surveyed, 134 libraries (80%) offered mobile reference services in some format via both mobile websites and dedicated apps (see fig. 10). figure 10. percentage of libraries offering mobile reference services. mobile reference services are described in this study as a direct way to contact the library via its mobile site. this can be done via chat, which functions similarly to instant messaging, text messaging (a patron can text a reference request to a specified text message number), or a web form (mobile friendly and reachable from remote devices) (see fig. 11). the web form, which was found on the websites of 127 of the 134 libraries (95%), was the most often utilized channel for mobile reference transactions compared to other services (see fig. 11). the user’s name, email address (and sometimes their library card or branch location), as well as their inquiry, were required. users’ phone numbers can be blank and are not collected. the librarian would then answer through email (or phone, if provided and applicable). the web form is available seven days a week, 24 hours a day. the user can submit at any time and receive a response when the librarian is available, which is convenient for both parties. 11% 89% no yes information technology and libraries march 2023 services to mobile users 14 liu and lewis figure 11. major forms of mobile reference service. chat or instant messaging is the second most common type of mobile reference service and was used by 74 (55%) of the 134 libraries that offered mobile reference services. chat rooms were set up in several libraries during specific hours of the day. for example, from 11 a.m. to 1 p.m., the boston public library (massachusetts) hosts a chat session. outside of those hours, this feature is not available. the limitation of the chat option for some libraries is that it works on a computer but not on a mobile device. also, the chat feature was unavailable outside of libraries’ standard operating hours. the sms text option was chosen by 36 (27%) of the libraries. the fact that many questions require a lengthy response or back-and-forth conversation can sometimes make this more challenging for librarians. if a patron has a short inquiry, the text option is convenient; nevertheless, this is most often used when the library is open. in addition to the text function, all 36 libraries offered another form of mobile reference service. thirty-five libraries offered the web form in addition to the text alternative. while most libraries provide only one form of mobile reference service, a few provide three or more such options. out of 134 libraries that provided mobile reference services, 56 (42%) provided only one service and 49 (37%) provided two. only 30 libraries (22%) provided all three services (chat, sms, and web form) (see fig. 12). the provo city library (utah) combines all three services in one chat box in the example shown in figure 13. this allows a user to ask a question and then continue the conversation using the technique of their choice. presently, these tools are more frequently observed in public libraries using libraryh3lp as opposed to mosio or libanswers, etc. 27% 55% 95% 0% 20% 40% 60% 80% 100% text/sms chat/im web form information technology and libraries march 2023 services to mobile users 15 liu and lewis figure

reserving a computer, museum pass, study room, meeting room, and show space are among the mobile reservation services that were examined. at least one of these was available at 106 libraries (70%) (see fig. 14). this finding indicated that mobile reservation services became widely used as a result of the covid-19 pandemic in the surveyed libraries. 0% 5% 10% 15% 20% 25% 30% 35% 40% 45% one form

many libraries remained closed throughout the survey study period, making it difficult for patrons to book conference rooms, study rooms, or exhibit space. some libraries that were open had meeting rooms and study rooms that were not available for use due to social distancing or other municipal standards. however, the option to reserve these rooms was still available on the website at the time of the analysis. some libraries supplied meeting space information but required patrons to make a reservation by contacting them. some libraries, such as the salt lake city public library in utah, closed their actual meeting rooms but offered rental of virtual meeting rooms while their physical meeting rooms were closed to the public (see fig. 15). others offer not just rooms, but outdoor and large areas. the indianapolis public library has an auditorium, an atrium, and a garden that are available to rent for a meeting—or even a wedding (the online form can be filled out requesting the date and the space for all types of events). 70% 30% yes no information technology and libraries march 2023 services to mobile users 17 liu and lewis figure 15. the salt lake city public library’s online announcement. while many events can take place at a library, the spaces or rooms that could be reserviced, such as wedding and exhibit spaces or rooms, are not commonly offered (see fig. 16). rather, the rooms at most libraries are used for either meetings or study sessions. the most common mobile reservation is for a meeting room, as 79 libraries (75%) out of the 106 libraries offering mobile reservation services allow patrons to reserve this space online (although, again, this service may not currently be available because of covid-19). study rooms are less commonly offered, with only 24 libraries (23%) offering mobile reservations for those online. however, some study rooms may be included with meeting rooms at some libraries. because libraries are closed or have covid-19 restrictions, book-a-librarian and reserve computer services are also paused. some libraries have pivoted to booking a librarian for a virtual meeting (34, or 32%), but often, that is just done through reference services. many libraries are limiting computer use and, as such, booking one can only be done in person to limit the number of people on the computers at one time. only 10 libraries (9%) of the libraries offering mobile reservations provide a service where a patron can reserve a computer. libraries are typically a great resource for free or discounted museum passes, but with some museums closed or having limited hours, some museum passes may not be available either. only 36 (34%) of the 106 libraries offering mobile reservation services allow patrons to book a museum pass online. information technology and libraries march 2023 services to mobile users 18 liu and lewis figure 16. percentage of libraries offering reservation of various kinds of services via a mobile interface mobile printing services become an emerging phenomenon the ability to print from a laptop computer or a mobile device is a newer service that many libraries are starting to offer to their patrons. with libraries being closed because of covid -19, the mobile printing service has become even more important. patrons can send a printing job to the library and then pick it up curbside. this service is another way libraries are adapting to the world during a pandemic. most libraries (114, or 76%) do offer mobile printing (see fig. 17). the majority of these libraries have their users download a specific app that allows them to connect to the library’s printers remotely with a variety of instructions. some libraries offer the ability to print wirelessly, where a user can connect to the library’s wi-fi (even in the parking lot if the library is closed) and send a document to the library that way. in this analysis, wireless printing and mobile printing are included together, as it is difficult to differentiate them because of the pandemic. as part of a remote service, some libraries are also starting to offer 3-d printing services, allowing patrons to submit 3-d print jobs from their mobile devices. this typically is also done through a specific app and sometimes comes with a fee allowing users to 3-d print and then pick the product up curbside. some libraries include this service as part of their makerspace and make it available for free with a library card. overall, 17 libraries (11%) offer 3-d printing. as more locations are utilizing 3-d printing technology, libraries can offer such 3-d service libraries to the general public wisely. 9% 23% 32% 34% 75% 0% 10% 20% 30% 40% 50% 60% 70% 80% computer study room librarian museum pass meeting room information

available via mobile devices patrons should be able to access databases via their mobile sites. when consumers think of public library services, databases are not always the first thing that comes to mind. however, when users were at home and libraries were closed, it was critical for patrons to have access to these databases. a library card was necessary to access the majority, if not all, of the databases. some libraries locked their databases behind a login screen so users can’t access them without a valid library card. a wide range of databases were available, and some libraries seemed to cater to their target audiences, with some offering more databases geared at children or teens (abc mouse, tumblebooks) and others focusing on their adult patrons (consumer reports, valuline). ancestry, gale (which includes academic onefile), and learning express (also known as prepstep) were the most widely used databases and were mentioned by 108 libraries (72%) of the 150 libraries that have databases available through their library mobile websites. table 1 lists the most commonly offered databases. many others were available at various libraries across the country, but none were offered by more than 10 percent of the libraries examined. social media bridges mobile devices from libraries to patrons all the libraries surveyed have social media links on their mobile websites. some libraries include apps that connect to social networking. every library had a facebook page, and almost all had a youtube channel (96%) or an instagram account (95%). the amount of access to some of these pages varies. one expectation from users is that all libraries would promote their social media on their main (or contact us) page, but some did not do so. figures were double-checked by browsing youtube, instagram, and twitter for each library. a youtube channel with fewer than 20 subscribers and postings was found for several libraries. ninety-three percent of libraries use their twitter accounts to promote their programming and other activities. following the listing of the primary social media, some libraries have a “drop-off” for how they interact with their users (see fig. 18). only 48 libraries (32%) used pinterest, and fewer used flickr (27, or 18%) or linkedin (25, or 17%). a very small percentage used tumblr (10, or 7%) or goodreads (6, or 4%). it is possible that more of these libraries used these social media channels but did not include the logo on their web page with their other social media. an extensive check was done on youtube, twitter, and instagram to verify that the libraries had a social media presence on those channels. these are the primary ways libraries connect users to their services, as they are the more popular on social media. other social media used include blogs from each library, e-newsletters, podcasts, rss feeds, vimeo, and tiktok. actions and barriers to advance mobile services despite the fact that more individuals are visiting libraries again and the facilities are open, many users might be hesitant to do so. fifty-six percent of the 54 libraries responding to the survey questionnnarie said they would like to provide more mobile services in the future (see fig. 19). information technology and libraries march 2023 services to mobile users 21 liu and lewis figure 18. percentage of public libraries using

looking to add, the two most common responses were: an app and text services. both responses were given by seven (21%) out of the 33 libraries that responded. the sms texting service was not just mobile reference, but also text notifications for program updates or reminders or account notifications. the rest of the responses were spread out, in that three libraries (9%) said that they were looking to add chat features and two libraries (6%) were looking to add mobile printing. other answers to the question by a single library included bookmobile, mobile checkout, and virtual story time. many libraries aspire to expand their offering of mobile reference services. the number of libraries that employ chat and sms text messaging appears to be substantial in the upcoming year. considerations are being given to expanding mobile services at libraries (see fig. 20). a total of 34 libraries responded, with the most common considerations being getting to know the community and promoting/marketing the services (18% of the libraries responded for each). a popular mobile service does not imply it will work for patrons, according to the surveyed libraries. the advice from survey respondents was to really attempt to figure out what people want and then give it to them. figure 20. percentage of libraries giving consideration to expanding mobile services to various areas. the research showed that libraries frequently test services to see what works and test services frequently to make sure they are operating properly. one library urged other libraries to do the best they could with what they had. they recognized that their customers were frustrated by their inability to provide mobile services and urged that they push out whatever mobile offerings they could. they agreed that it would not be flawless, but users would prefer to communicate with library staff when encountering a bug-free app/website/service. staffing, technology, and money were by far the three most significant difficulties that libraries faced, based on the response from 36 libraries (see fig. 21). while expanding mobile services is something that these libraries want to accomplish,

information technology and libraries march 2023 services to mobile users 23 liu and lewis understand how to utilize them is difficult. furthermore, many upgrades necessitate funding, whether for staff training or the development of an app. figure 21. percentage of libraries facing resource challenges in offering mobile services. one of the top technical issues is ensuring that their mobile services are interoperable across several platforms. six libraries (17%) indicated that anything they add will operate on both android and apple platforms on mobile devices. another technological challenge is that any service the library introduces must be compatible with what they already have. when new apps or platforms are required, integrating them with existing technology can be tricky. conclusion and suggestions for further study after examining 151 public libraries across the united states, it is obvious that libraries are attempting to engage with their consumers via mobile services. all 151 libraries have either a mobile website or one that is mobile friendly. as such, the website, in all cases, contained contact information, library locations and hours, access to the library catalog, and the ability to log in and renew or reserve a book. during a period when many libraries were closed, these primary services were critical in connecting with the bulk of users. libraries adapted to the times by introducing curbside service, which allowed users to place holds on books or materials remotely using their mobile devices and then return to the library to pick up their holds without having to go inside. a bit more than half of the libraries polled had a specialized mobile app that performs some of the same functions as the mobile website. some libraries are considering developing an app to help their patrons in the future. many libraries have incorporated remote reference services, such as booking a librarian with an online reservation, sms notifications, and chat, in response to the pandemic. these services enable the library to communicate with its patrons when face-to-face interaction is not possible. 17% 17% 23% 0% 5% 10% 15% 20% 25% money technology staff information technology and libraries march 2023 services to mobile users 24 liu and lewis libraries are continually assessing their mobile services to determine what will work best for their users. mobile printing, chat, and an app are among the new features they’re introducing. according to a poll, 56 percent of libraries plan to continue to provide mobile services in the future. many businesses, including libraries, have had to reconsider and adapt their business models. libraries are relying on mobile services to maintain their relationships with their clients as the world continues to change because of covid-19 and the rise of mobile devices. endnotes 1 statcounter global stats, “mobile and tablet internet usage exceeds desktop for first time worldwide,” press release, november 1,

efficient storage of text documents in digital libraries przemysław skibiński (inikep@ii.uni.wroc.pl) is [qy: title?], institute of computer science, university of wrocław, poland. jakub swacha (jakubs@uoo.univ.szczecin.pl) is [qy: title?], institute of information technology in management, university of szczecin, poland. przemysław skibiński and jakub swacha the efficient storage of text documents in digital libraries in this paper we investigate the possibility of improving the efficiency of data compression, and thus reducing storage requirements, for seven widely used text document formats. we propose an open-source text compression software library, featuring an advanced word-substitution scheme with static and semidynamic word dictionaries. the empirical results show an average storage space reduction as high as 78 percent compared to uncompressed documents, and as high as 30 percent compared to documents compressed with the free compression software gzip. i t is hard to expect the continuing rapid growth of global information volume not to affect digital libraries.1 the growth of stored information volume means growth in storage requirements, which poses a problem in both technological and economic terms. fortunately, the digital librarys’ hunger for resources can be tamed with data compression.2 the primary motivation for our research was to limit the data storage requirements of the student thesis electronic archive in the institute of information technology in management at the university of szczecin. the current regulations state that every thesis should be submitted in both printed and electronic form. the latter facilitates automated processing of the documents for purposes such as plagiarism detection or statistical language analysis. considering the introduction of the three-cycle higher education system (bachelor/master/doctorate), there are several hundred theses added to the archive every year. although students are asked to submit microsoft word–compatible documents such as doc, docx, and rtf, other popular formats such as tex script (tex), html, ps, and pdf are also accepted, both in the case of the main thesis document, containing the thesis and any appendixes that were included in the printed version, and the additional appendixes, comprising materials that were left out of the printed version (such as detailed data tables, the full source code of programs, program manuals, etc.). some of the appendixes may be multimedia, in formats such as png, jpeg, or mpeg.3 notice that this paper deals with text-document compression only. although the size of individual text documents is often significantly smaller than the size of individual multimedia objects, their collective volume is large enough to make the compression effort worthwhile. the reason for focusing on text-document compression is that most multimedia formats have efficient compression schemes embedded, whereas text document formats usually either are uncompressed or use schemes with efficiency far worse than the current state of the art in text compression. although the student thesis electronic archive was our motivation, we propose a solution that can be applied to any digital library containing text documents. as the recent survey by kahl and williams revealed, 57.5 percent of the examined 1,117 digital library projects consisted of text content, so there are numerous libraries that could benefit form implementation of the proposed scheme.4 in this paper, we describe a state-of-the-art approach to text-document compression and present an opensource software library implementing the scheme that can be freely used in digital library projects. in the case of text documents, improvement in compression effectiveness may be obtained in two ways: with or without regard to their format. the more nontextual content in a document (e.g., formatting instructions, structure description, or embedded images), the more it requires format-specific processing to improve its compression ratio. this is because most document formats have their own ways of describing their formatting, structure, and nontextual inclusions (plain text files have no inclusions). for this reason, we have developed a compound scheme that consists of several subschemes that can be turned on and off or run with different parameters. the most suitable solution for a given document format can be obtained by merely choosing the right schemes and adequate parameter values. experimentally, we have found the optimal subscheme combinations for the following formats used in digital libraries: plain text, tex, rtf, text annotated with xml, html, as well as the device-independent rendering formats ps and pdf.5 first we discuss related work in text compression, then describe the basis of the proposed scheme and how it should be adapted for particular document formats. the section “using the scheme in a digital library project” discusses how to use the free software library that implements the scheme. then we cover the results of experiments involving the proposed scheme and a corpus of test files in each of the tested formats. n text compression there are two basic principles of general-purpose data compression. the first one works on the level of character sequences, the second one works on the level of przemysław skibiński (inikep@ii.uni.wroc.pl) is associate professor, institute of computer science, university of wrocław, poland. jakub swacha (jakubs@uoo.univ.szczecin .pl) is associate professor, institute of information technology in management, university of szczecin, poland. 144 information technology and libraries | september 2009 individual characters. in the first case, the idea is to look for matching character sequences in the past buffer of the file being compressed and replace such sequences with shorter code words; this principle underlies the algorithms derived from the concepts of arbraham lempel and jacob ziv (lz-type).6 in the second case, the idea is to gather frequency statistics for characters in the file being compressed and then assign shorter code words for frequent characters and longer ones for rare characters (this is exactly how huffman coding works—what arithmetic coding assigns are value ranges rather than individual code words).7 as the characters form words, and words form phrases, there is high correlation between subsequent characters. to produce shorter code words, a compression algorithm either has to observe the context (understood as several preceding characters) in which the character appeared and maintain separate frequency models for different contexts, or has to first decorrelate the characters (by sorting them according to their contexts) and then use an adaptive frequency model when compressing the output (as the characters’ dependence on context becomes dependence on position). whereas the former solution is the foundation of prediction by partial match (ppm) algorithms, burrows-wheeler transform (bwt) compression algorithms are based on the latter.8 witten et al., in their seminal work managing gigabytes, emphasize the role of data compression in text storage and retrieval systems, stating three requirements for the compression process: good compression, fast decoding, and feasibility of decoding individual documents with minimum overhead.9 the choice of compression algorithm should depend on what is more important for a specific application: better compression or faster decoding. an early work of jon louis bentley and others showed that a significant improvement in text compression can be achieved by treating a text document as a stream of space-delimited words rather than individual characters.10 this technique can be combined with any general-purpose compression method in two ways: by redesigning character-based algorithms as word-based ones or by implementing a two-stage scheme whose first step is a transform replacing words with dictionary indices and whose second step is passing the transformed text through any generalpurpose compressor.11 from the designer’s point of view, although the first approach provides more control over how the text is modeled, the second approach is much easier to implement and upgrade to future general-purpose compressors.12 notice that the separation of the wordreplacement stage from the compression stage does not imply that two distinct programs have to be used—if only an appropriate general-purpose compression software library is available, a single utility can use it to compress the output of the transform it first performed. an important element of every word-based scheme is the dictionary of words that lists character sequences that should be treated as single entities. the dictionary can be dynamic (i.e., constructed on-line during the compression of every document),13 static (i.e., constructed off-line before the compression stage and once for every document of a given class—typically, the language of the document determines its class),14 or semidynamic (i.e., constructed off-line before compression stage but individually for every document).15 semidynamic dictionaries must be stored along with the compressed document. dynamic dictionaries are reconstructed during decompression (which makes the decoding slower than in the other cases). when the static dictionary is used, it must be distributed with the decoder; since a single dictionary is used to compress multiple files, it usually attains the best compression ratios, but it is only effective with documents of the class it was originally prepared for. n the basic compression scheme the basis of our approach is a word-based, lossless text compression scheme, dubbed compression for textual digital libraries (ctdl). the scheme consists of up to four stages: 1. document decompression 2. dictionary composition 3. text transform 4. compression stages 1–2 are optional. the first is for retrieving textual content from files compressed poorly with generalpurpose methods. it is only executed for compressed input documents. it uses an embedded decompressor for files compressed using the deflate algorithm,16 but an external tool—precomp—is used to decode natively compressed pdf documents.17 the second stage is for constructing the dictionary of the most frequent words in the processed document. doing so is a good idea when the compressed documents have no common set of words. if there are many documents in the same language, a common dictionary fares better—it usually does not pay off to store an individual dictionary with each file because they all contain similar lists of words. for this reason we have developed two variants of the scheme. the basic ctdl includes stage 2; therefore it can use a document-specific semidynamic dictionary in the third stage. the ctdl+ variant uses a static dictionary common for all files in the same language; therefore it can omit stage 2. during stage 2, all the potential dictionary items that meet the word requirements are extracted from the document and then sorted according to their frequency the efficient storage of text documents in digital libraries | skibiński and swacha 145 to form a dictionary. the requirements define the minimum length and frequency of a word in the document (by default, 2 and 6 respectively) as well as its content. only the following kinds of strings are accepted into the dictionary: n a sequence of lowercase and uppercase letters (“a”–“z”, “a”–“z”) and characters with ascii code values from range 128–255 (thus it supports any typical 8-bit text encoding and also utf-8) n url address prefixes of the form “http:// domain/,” where domain is any combination of letters, digits, dots, and dashes n e-mails—patterns of the form “login@domain,” where login and domain are any combination of letters, digits, dots, and dashes n runs of spaces stage 3 begins with parsing the text into tokens. the tokens are defined by their content; as four types of content are distinguished, there are also four classes of tokens: words, numbers, special tokens, and characters. every token is then encoded in a way that depends on the class it belongs to. the words are those character sequences that are listed in the dictionary. every word is replaced with its dictionary index, which is then encoded using symbols that are rare or nonexistent in the input document. indexes are encoded with code words that are between one and four bytes long, with lower indexes (denoting more frequent words) being assigned shorter code words. the numbers are sequences of decimal digits, which are encoded with a dense binary code, and, similarly to letters, placed in a separate location in the output file. the special tokens can be decimal fractions, ip numerical addresses, dates, times, and numerical ranges. as they have a strict format and differ only in numerical values, they are encoded as sequences of numbers.18 finally, the characters are the tokens that do not belong to any of the aforementioned group. they are simply copied to the output file, with the exception of those rare characters that were used to construct code words; they are copied as well, but have to be preceded with a special escape symbol. the specialized transform variants (see the next section) distinguish three additional classes from the character class: letters (words not in the dictionary), single white spaces, and multiple white spaces. stage 4 could use any general-purpose compression method to encode the output of stage 3. for this role, we have investigated several open-licensed, generalpurpose compression algorithms that differ in speed and efficiency. as we believe that document access speed is important to textual digital libraries, we have decided to focus on lz–type algorithms because they offer the best decompression times. ctdl has two embedded backend compressors: the standard deflate and lzma, wellknown for its ability to attain high compression ratios.19 n adapting the transform for individual text document formats the text document formats have individual characteristics; therefore the compression ratio can be improved by adapting the transform for a particular format. as we noted in the introduction, we propose a set of subschemes (modifications of the original processing steps or additional processing steps) that can help compression— provided the issue that a given subscheme addresses is valid for the document format being compressed. there are two groups of subschemes: the first consists of solutions that can be applied to more than one document format. it includes n changing the minimum word frequency threshold (the “minfr” column in table 1) that a word must pass to be included in the semidynamic dictionary (notice that no word can be added to a static dictionary); n using spaceless word model (“wdspc” column in table 1) in which a single space between two words is not encoded at all; instead, a flag is used to mark two neighboring words that are not separated by a space; n run-length encoding of multiple spaces (“spruns” column in table 1); n letter containers (“letcnt” column in table 1), that is, removing sequences of letters (belonging to words that are not included in the dictionary) to a separate location in the output file (and leaving a flag at their original position). table 1 shows the assignment of the mentioned subschemes to document formats, with “+” denoting that a given subscheme should be applied when processing a given document format. notice that we use different subschemes for the same format depending on whether a semidynamic (ctdl) or static (ctdl+) dictionary is used. the remaining subschemes are applied for only one document format. they attain an improvement in compression performance by changing the definition of acceptable dictionary words, and, in one case (ps), by changing the definition of number strings. the encoder for the simplest of the examined formats—plain text files—performs no additional formatspecific processing. the first such modification is in the tex encoder. the difference is that words beginning with “\” (tex 146 information technology and libraries | september 2009 instructions) are now accepted in the dictionary. the modification for pdf documents is similar. in this case, bracketed words (pdf entities)— for example “(abc)”—are acceptable as dictionary entries. notice that pdf files are internally compressed by default—the transform can be applied after decompressing them into textual format. the precomp tool is used for this purpose. the subscheme for ps files features two modifications: its dictionary accepts words beginning with “/” and “\” or ending with “(“, and its number tokens can contain not only decimal but also hexadecimal digits (though a single number must have at least one decimal digit). the hexadecimal number must be at least 6 digits long, and is encoded with a flag: a byte containing its length (numbers with more than 261 digits are split into parts) and a sequence of bytes, each containing two digits from the number (if the number of digits is odd, the last byte contains only one digit). for rtf documents, the dictionary accepts the “\”-preceded words, like the tex files. moreover, the hexadecimal numbers are encoded in the same way as in the ps subscheme so that rtf documents containing images can be significantly reduced in size. specialization for xml is roughly the transform described in our earlier article, “revisiting dictionarybased compression.”20 it allows for xml start tags and entities to be added to dictionary, and it replaces every end tag respecting the xml well-formedness rule (i.e., closing the element opened most recently) with a single flag. it also uses a single flag to denote xml attribute value begin and end marks. html documents are handled similarly. the only difference is that the tags that, according to the html 4.01 specification, are not expected to be followed by an endtag (base, link, xbasehref, br, meta, hr, img, area, input, embed, param and col) are ignored by the mechanism replacing closing tags (so that it can guess the correct closing tag even after the singular tags were encountered).21 n using the scheme in a digital library project many textual digital libraries seriously lack text compression capabilities, and popular digital library systems, such as greenstone, have no embedded efficient text compression.22 therefore we have decided to develop ctdl as an open-source software library. the library is free to use and can be downloaded from www.ii.uni.wroc .pl/~inikep/research/ctdl/ctdl09.zip. the library does not require any additional nonstandard libraries. it has both the text transform and back-end compressors embedded. however, compressing pdf documents requires them to be decompressed first with the free precomp tool. the compression routines are wrapped in a code selecting the best algorithm depending on the chosen compression mode and the input document format. the interface of the library consists of only two functions: ctdl_encode and ctdl_decode, for, respectively, compressing and decompressing documents. ctdl_encode takes the following parameters: n char* filename—name of the input (uncompressed) document n char* filename_out—name of the output (compressed) document n efiletype ftype—format of the input document, defined as: enum efiletype { html, pdf, ps, rtf, tex, txt, xml}; n edictionarytype dtype—dictionary type, defined as: enum edictionarytype { static, semidynamic }; ctdl_decode takes the following parameters: n char* filename—name of the input (compressed) document n char* filename_out—name of the output (decompressed) document table 1. universal transform optimizations ctdl

text documents in digital libraries | skibiński and swacha 147 the library was written in the c++ programming language, but a compiled static library is also distributed; thus it can be used in any language that can link such libraries. currently, the library is compatible with two platforms: microsoft windows and linux. to use static dictionaries, the respective dictionary file must be available. the library is supplied with an english dictionary trained on a 3 gb text corpus from project gutenberg.23 seven other dictionaries—german, spanish, finnish, french, italian, polish, and russian— can be freely downloaded from www.ii.uni.wroc.pl/~inikep/ research/dicts. there also is a tool that helps create a new dictionary from any given corpus of documents, available from skibiński upon request via e-mail (inikep@ii.uni .wroc.pl). the library can be used to reduce the storage requirements or also to reduce the time of delivering a requested document to the library user. in the first case, the decompression must be done on the server side. in the second case, it must be done on the client side, which is possible because stand-alone decompressors are available for microsoft windows and linux. obviously, a library can support both options by providing the user with a choice whether a document should be delivered compressed or not. if documents are to be decompressed client-side, the basic ctdl, using a semidynamic dictionary, seems handier, since it does not require the user to obtain the static dictionary that was used to compress the downloaded document. still, the size of such a dictionary is usually small, so it does not disqualify ctdl+ from this kind of use. n experimental results we tested ctdl experimentally on a benchmark set of text documents. the purpose of the tests was to compare the storage requirements of different document formats in compressed and uncompressed form. in selecting the test files we wanted to achieve the following goals: n test all the formats listed in table 1 (therefore we decided to choose documents that produced no errors during document format conversion) n obtain verifiable results (therefore we decided to use documents that can be easily obtained from the internet) n measure the actual compression improvement from applying the proposed scheme (apart from the rtf format, the scheme is neutral to the images embedded in documents; therefore we decided to use documents that have no embedded images) for these reasons, we used the following procedure for selecting documents to the test set. first, we searched the project gutenberg library for tex documents, as this format can most reliably be transformed into the other formats. from the fifty-one retrieved documents, we removed all those containing images as well as those that the htlatex tool failed to convert to html. in the eleven remaining documents, there were four jane austen books; this overrepresentation was handled by removing three of them. the resulting eight documents are given in table 2. from the tex files we generated html, pdf, and ps documents. then we used word 2007 to transform html documents into rtf, doc, and xml (thus this is the microsoft word xml format, not the project gutenberg xml format). the txt files were downloaded from project gutenberg. the tests were conducted on a low-end amd sempron 3000+ 1.80 ghz system with 512 mb ram and a seagate 80 gb ata drive, running windows xp sp2. for comparison purposes, we used three generalpurpose compression programs: n gzip implementing deflate n

bitrate of 8 bits per character. looking at the results obtained for txt documents (table 3), we can see an average improvement of 17 percent for ctdl and 27 percent for ctdl+ compared to the baseline deflate implementation. compared to the baseline lzma implementation, the improvement is 10 percent for ctdl and 20 percent for ctdl+. also, ctdl+ combined with lzma compresses txt documents 31 percent better than gzip, 11 percent better than bzip2, and slightly better than the state-of-the-art ppmvc implementation. in case of tex documents (table 4), the gzip results were improved, on average, by 16 percent using ctdl and by 26 percent using ctdl+; the numbers for lzma are 10 percent for ctdl and 19 percent for ctdl+. in a cross-method comparison, ctdl+ with lzma beats gzip by 31 percent, bzip2 by 10 percent, and attains results very close to ppmvc. on average, deflate-based ctdl compressed xml documents 20 percent better than the baseline algorithm (table 5), and with ctdl+ the improvement rises to 26 percent. ctdl improves lzma compression by 11 percent, and ctdl+ improves it by 18 percent. ctdl+ with lzma beats gzip by 33 percent, bzip2 by 8 percent, and loses only 4 percent to ppmvc. similar results were obtained for html documents (table 6): they were compressed with ctdl and deflate 18 percent better than with the deflate algorithm alone, and 27 percent better with ctdl+. lzma compression efficiency is improved by 11 percent with ctdl and 20 percent with ctdl+. ctdl+ with lzma beats gzip by 33 percent, bzip2 by 9 percent, and loses only 2 percent to ppmvc. for rtf documents (table 7), the gzip results were improved, on average, by 18 percent using ctdl, and 25 percent using ctdl+; the numbers for lzma are respectively 9 percent for ctdl and 17 percent for ctdl+. in a cross-method comparison, ctdl+ with lzma beats gzip by 34 percent, bzip2 by 7 percent, and loses 5 percent to ppmvc. although there is no mode designed especially for doc documents in ctdl (table 8), the basic txt mode was used, as it was found experimentally to be the best choice available. the results show it managed to improve deflate-based compression by 9 percent using ctdl, and by 21 percent using ctdl+, whereas lzma-based compression was improved respectively by 4 percent for ctdl and 14 percent for ctdl+. combined with lzma, ctdl+ compresses doc documents 30 percent better than gzip, 13 percent better than bzip2, and 1 percent better than ppmvc. in case of ps documents (table 9), the gzip results were improved, on average, by 5 percent using ctdl, and by 8 percent using ctdl+; the numbers for lzma improved 3 percent for ctdl and 5 percent for ctdl+. in a cross-method comparison, ctdl+ with lzma beats gzip by 8 percent, losing 5 percent to bzip2 and 7 percent to ppmvc. finally, ctdl improved deflate-based compression of pdf documents (table 10) by 9 percent using ctdl and 10 percent using ctdl+ (compared to gzip; the numbers are table 5.

september 2009 much higher if compared to the embedded pdf compression—see “native” column in table 10); the numbers for lzma are respectively 7 percent for ctdl and 10 percent for ctdl+. combined with lzma, ctdl+ compresses pdf documents 28 percent better than gzip, 4 percent better than bzip2, and 5 percent worse than ppmvc. the results presented in tables 3–10 show that ctdl manages to improve compression efficiency of the general-purpose algorithms it is based on. the scale of improvement varies between document types, but for most of them it is more than 20 percent for ctdl+ and 10 percent for ctdl. the smallest improvement is achieved in case of ps (about 5 percent). figure 1 shows the same results in another perspective: the bars show how much better compression ratios were obtained for the same documents using different compression schemes compared to gzip with default options (0 percent means no improvement). compared to gzip, ctdl offers a significantly better compression ratio at the expense of longer processing time. the relative difference is especially high in case of decompression. however, in absolute terms, even in the worst case of pdf, the average delay between ctdl+ and gzip is below 180 ms for compression and 90 ms for decompression per file. taking into consideration the low-end specification of the test computer, these results table 6.

151 certainly seem good enough for practical applications. compared to lzma, ctdl offers better compression and a shorter compression time at the expense of longer decompression time. notice that the absolute gain in compression time is several times the loss in decompression time, and the decompression time remains short, noticeably shorter than bzip2’s and several times shorter than ppmvc’s. ctdl+ beats bzip2 (with the sole exception of ps documents) in terms of compression ratio and achieves results that are mostly very close to the resourcehungry ppmvc. n conclusions in this paper we addressed the problem of compressing text documents. although individual text documents rarely exceed several megabytes in size, their entire collections can have very large storage space requirements. although text documents are often compressed with general-purpose methods such as deflate, much better compression can be obtained with a scheme specialized for text, and even better if the scheme is additionally specialized for individual document formats. we have developed such a scheme (ctdl), beginning with a text transform designed earlier for xml documents and table 8.

requirements of each of the investigated document formats. it has two operation modes: basic ctdl and ctdl+ (the latter uses a common word dictionary for improved compression) and uses two back-end compression algorithms: deflate and lzma (differing in compression speed and efficiency). the improvement in compression efficiency, which can be observed in the experimental results, amounts to a significant reduction of data storage requirements, giving the reasons to use the library in both new and existing digital library projects instead of general-purpose compression programs. to facilitate this process, we implemented the scheme as an open-source software library under the same name, freely available at http://www.ii.uni.wroc . p l / ~ i n i k e p / re s e a rc h / c t d l /

(each hardware manufacturer implements a slightly different version of a programming language.) the translation requires changing things such as square brackets to parentheses, the word read to get, the word write to put, etc. these changes would have to have been done repeatedly throughout the program, but, in fact, were quite easily accomplished by using a text editor-a metaprogram that can be instructed to change all occurrences of, for example, the word read to the word get in a single pass. clas retained all of the features of peas , and became fully operational at lewis and clark in february of 1980. since then, new features have been added as the staff expressed a need for them. some are minor, such as having the computer recognize initial articles in titles . others are more significant : 1. searching for records in clas by author and title makes use of unlimited rightand left-handed truncation. this makes possible subject searching through k~y words in the title . for this purpose an extra terminal is provided at the reference desk. 2. clas permits the file to be searched by the name of the faculty member who requested the item, in addition to the eight other access points available in peas. 3. clas provides an activity report for any given period showing, for each fund, the amount ordered, the amount received, and the average cost per item . 4. clas can produce vendor reports showing for each vendor the average discount and the delivery schedule. 5. clas asks the operator to verify the cost of an item if the list price and cost differ by more than 30 percent. 6. clas allows the receipt of partial shipments. some of the enhancements to clas involved successive modifications. for example, one of the features of peas was the prevention of duplicate orders by matching new orders being input with records already in the database. a potential duplicate is reported if there is a match on both the author and the title fields . it was decided at the time of implementation at lewis and clark that this criterion was too restrictive, and clas was programmed to report a duplicate if only the title fields matched . after some months of experience, it turned out that even this requirement was excessively restrictive: a slight variation in the way a title was input would prevent a duplicate from showing up. the criterion was then further relaxed to signal duplicates if either the title or the author's last name matched. this, however, was too broad a net : although no duplicates were missed, ordering a book by wilson or smith produced a tedious list of potential duplicates. hence , the requirement was tightened slightly to look for a match in either the title or the author's last name and first initial. this final criterion is currently serving well the needs of the watzek library. what is important about this evolutionary process is that it illustrates the dynamic way in which a library can "fine-tune" an automated system that is receptive to user modifications. since peas is supposed to be a selfexplanatory system, it lacks any documentation. clas is still a self-explanatory system, but nevertheless a manual has been produced to describe all its features and to record programming information such as the structure of the files . one version of the documentation is kept in machine-readable form so that it can be easily updated to correspond to developments in the program . in conclusion, it can be stated that a library-application software package has been successfully transplanted from one institution to another, from one hardware environment to another, and in doing so has matured into a fuller and more flexible system, which it is hoped will, in turn, benefit other libraries contemplating the automation of their acquisitions operation .2 references 1. jenko lukac, "a no cost online acquisicommunications 101 tions system for a medium-size library," library journal 107:684-85 (march 15, 1980). 2.

this article presents the results of a quantitative analysis examining the effects of abnormal and extreme values on e-journal usage statistics. detailed are the step-by-step procedures designed specifically to identify and remove these values, termed outliers. by greatly deviating from other values in a sample, outliers distort and contaminate that data. between 2010 and 2011, e-journal usage at laurentian university’s j. n. desmarais library spiked because of illegal downloading. the identification and removal of outliers had a noticeable effect on e-journal usage levels. they represented more than 100,000 erroneous articles downloaded in 2010 and nearly 200,000 erroneous downloaded in 2011. introduction this article was written with two purposes in mind. first, it presents and discusses the results of a quantitative analysis that assessed how outlier values can influence usage statistics. second, and more important, it details the step-by-step procedures designed specifically to identify outliers and reduce their impact on the data. outliers are abnormal values that result in the corruption or contamination of data by artificially increasing or reducing average values.1 an outlier can thus be defined as a value that appears to greatly deviate from all other values in the sample,2 as an observation that seems to be inconsistent with the rest of the dataset,3 or as a very extreme observation requiring special attention because of potential impacts it may have on a summary of the data.4 they occur frequently in measurement data.5 the presence of outliers in usage data can significantly and negatively impact libraries. for libraries having e-resource subscription pricing based on usage statistics, the presence of outliers can contribute to unwarranted increases in subscription rates. for libraries that integrate eresource usage statistics into their collection development and management practices, the presence of outliers can affect decisions on purchase, retention, or elimination of particular eresources. evaluators can be fooled into thinking that a particular e-resource is heavily used and must be kept. further, the presence of extreme outliers is often the result of a malicious system alain r. lamothe (alomothe@laurentian.ca) is associate librarian, department of library and archives, laurentian university, sudbury, ontario, canada. mailto:alomothe@laurentian.ca information technology and libraries | june 2014 32 intrusion,6 as was experienced by the j. n. desmarais library of laurentian university in sudbury, ontario, canada.7 between june 2010 and may 2011, e-journal usage at the j. n. desmarais library spiked after a four-year period of stable annual usage levels.8 between 2006 and 2010, the total number of fulltext articles downloaded from the library’s e-journal collection ranged between 640,000 and 720,000 annually, with an average of 700,000 articles downloaded per year. but in 2010 that number dramatically increased to more than 857,000 full-text articles downloaded. this was followed by an additional 870,000 full-text articles downloaded in 2011. then, as suddenly and inexplicably as the increase had occurred, usage levels returned to the same quantities recorded in the years prior to 2010. a total of 716,000 full-text articles were downloaded in 2012. during this period of spiking usage the library received notifications and warnings from certain ejournal vendors of abnormally large numbers of full-text articles being downloaded over a relatively short period of time from the laurentian university ezproxy server’s ip address. this level of usage was a breach of license agreements. these vendors then proceeded to temporarily block laurentian university’s ezproxy access until they obtained assurances from the university that the offending accounts were no longer active. this action on the vendors’ part prevented any further suspected illegal downloading from occurring but also barred laurentian university students, staff, and faculty from authorized off-campus access. but not all vendors operated in this fashion and, unknown to the library at the time, full-text articles continued to be downloaded from other vendor sites in excessive amounts. either they were not monitoring excessive usage or they did not have the technical means to do so. regardless, in some cases certain e-journal titles recorded downloads thousands of times higher than normal. in some cases dozens of articles were being downloaded in seconds. the situation continued until late spring 2011, at which point it was discovered that confidential proxy account login information had been posted illegally on the web. with the login information of all compromised accounts now available, proxy managers were able to block their access at once, thereby ending the period of illegal downloading of laurentian university licensed material. web robots were suspected to have been involved. web robots, also referred to as internet bots or www robots, are automated software applications that run tasks on the web much as search engines do.9 they send requests to web servers to procure resources.10 some robots are developed with malicious intent and are designed to download entire websites for the purpose of copying the site,11 for autonomous logins to send spam,12 or for autonomous logins to steal confidential or copyright protected material.13 web robots specifically designed for the illegal procurement of copyright protected content are obviously of particular concern for libraries. unlawful downloading of full-text content occurs for many reasons. studies have clearly demonstrated that excessively high prices of digital content is a major drive for illegal downloads.14 misunderstanding and misinterpretation of copyright laws in addition to the importance of identifying and accommodating e-resources usage data for the presence of outliers | lamothe 33 unfamiliarity with and general apathy toward these same copyright laws further contribute to unlawful downloading of protected material.15 many students are unaware that the transmission of downloaded articles violates copyright laws and license agreements and often misunderstand the fair use aspect of copyright as meaning that the acquisition and distribution of licensed content for the purpose of education is allowed.16 in the minds of these students, distribution is permitted provided it is not for profit. librarians have also reported students systematically downloading all articles from recent journal issues not for the purpose of distribution or sale but rather to build their own personal collection.17 they are more concerned with obtaining resources quickly and completely rather than legally.18 aggravating the situation are students who firmly believe that by paying tuition they have permission to do whatever they wish with their institutions’ e-resources.19 some of these same students even use web robots to download as much as possible thereby saving them time and energy.20 they consider the downloaded item as their personal property. in fact, calluzzo and cante found that students displayed an ethical sense to personal property but became neutral if the property belonged to an enterprise.21 and solomon and o’brien found that 71 percent of students believed illegal copying to be a socially and ethically acceptable behavior.22 the j. n. desmarais library integrates e-resource usage into its collection development policy. as stated in the library’s collection development policy, “if the cost-per-use of an online resource is greater than the cost of an interlibrary loan for three consecutive years, this resource will be reviewed for cancellation.”23 in fact, this practice has been enforced for the past several years and has saved the library a considerable sum of money.24 for this reason, it is extremely important not to assume the accuracy of usage values without carefully examining the data. the artificial inflation of usage numbers could substantially cost the library if it was believed that an e-resource was beginning to experience an improvement in usage when, in actuality, it was not the case. the decision to keep this resource could cost the library tens of thousands of dollars before it was realized that the high number of searches or downloads recorded were not reflective of actual usage but were rather the result of data recording errors or illegal activity. regrettably, libraries will continue to deal with the consequences of copyright infringement, even if the library itself is not at fault. it is, however, important to recognize and understand that publishers are businesses and like any business, expect financial gain.25 even though e-resource piracy is currently very small, the risk of it becoming the single greatest threat to the industry is quite real. both music and film industries have been greatly affected by piracy for nearly two decades, and everyone witnessed the damaging effect it had. publishers have learned from this and will not allow it to happen to them as well.26 unfortunately for all parties involved, the nature of e-resources has made them extremely easy to copy.27 information technology and libraries | june 2014 34 method the following methodology will detail the step-by-step procedures to identify and deal with suspected outliers. all data manipulation and calculations were executed in microsoft excel for mac 2011 (version 14.3.2). all tables and figures were generated using the same version of excel. the first step is to identify suspected outliers by visually examining an entire usage dataset. a dataset is defined as a collection of related data corresponding to the contents of a single database table in which each column represents a particular variable and each row, a given member of the dataset in question.28 for this reason, the term dataset will be referred to in this paper as a grouping of data from any single spreadsheet. each spreadsheet contains the number of full-text articles downloaded per year per vendor. each dataset was downloaded from vendors’ sites as jr1 counter-compliant reports, which detail the number of successful full-text articles downloaded per month and per journal for a given year. all vendors provided jr1 counter-compliant reports that were downloaded as excel spreadsheets. each spreadsheet, or dataset, contained the list of e-journal title and the number of articles downloaded for each title per month (see table 1). each dataset was then visually inspected in its entirety for suspected outliers. january february march april may june july august september october november december polymer 12

outliers are highlighted in bold. since it was impractical to include the entire spreadsheet, table 1 provides an excerpt from a 2010 jr1 counter-compliant report containing five suspected outliers that have been marked for identification. the suspected outliers are highlighted in bold. the first of these extreme values belongs to the title polymer and was recorded in october. compared to the other values for polymer, it stands out dramatically at 15,123 articles downloaded. the second and third extreme values belong to surface and coatings technology and are recorded for the months of october (3,771 downloads) and november (5,428 downloads). the fourth is the 6,436 articles downloaded in june from international journal of radiation oncology and the fifth from journal of catalysis in november (6,693 downloads). these five values greatly deviate from the other values recorded the importance of identifying and accommodating e-resources usage data for the presence of outliers | lamothe 35 for each e-journal title. for polymer, the next highest value is 109 articles downloaded in november 2010, making the suspected outlier almost 14,000 percent greater. now that the suspected outliers have been identified, they must be compared quantitatively to the rest of the values recorded for their corresponding titles and only for their corresponding titles. for example, to test the probability that the value of 15,123 downloads recorded in october 2010 for polymer is indeed an outlier, the comparison must include all other 2010 polymer monthly values plus all other available polymer values. this is achieved by copying all 2010 polymer monthly values into a separate blank spreadsheet and then adding all other polymer monthly values from all other available years to that same spreadsheet (see table 2). this new spreadsheet can be labeled dataset 2, with dataset 1 being the original jr1 report downloaded from the vendor. suspected usage outliers from an e-journal need to be compared to other usage values of that particular title because each e-journal tends to be used differently. it would be inaccurate to test for an outlier by comparing it to the values of all other e-journals included in a collection and would be like comparing apples to oranges. january february march april may june july august september october november december polymer 2009 27 14 35 22

polymer’s usage values from all available jr1 counter-compliant reports. the suspected outlier is highlighted in bold. table 2 provides the number of articles downloaded for the title polymer over a four-year period. these were the only jr1 reports available from the vendor. the suspected outlier is highlighted in bold. when visually comparing the suspected outlier of 15,123 downloads to the rest of the values in dataset 2, it again appears to be an extreme. the next highest value being 638 articles downloaded during march 2011, making the suspected outlier 2,200 percent greater than the next highest value in the dataset. all further outlier testing and accommodating will be performed on this table. the dixon q test was chosen to test for outliers. it is simple to use and designed to test for a small number of outliers in a dataset.29 the q value is calculated by measuring the difference in the gap between the suspected outlier and the next value over the range of values in the dataset (e.g., outlier—next value/largest—smallest). the gap is the absolute difference between the outlier and the closest number to it. to facilitate the calculation, the data should be arranged in order of increasing value with the smallest value at the front of the sequence and the largest value at the end of the sequence. for example, using the data in table 2 each value is be arranged beginning with 4, 5, 5, 7, . . . , 345, 638, information technology and libraries | june 2014 36 and finally ending with 15,123. the calculation would thus be (15,123−638) / (15,123−4) = 0.9581. the calculated q value will also be represented by the symbol of qvalue from this point onward, making qvalue = 0.9581. the next step is to compare the calculated qvalue to the critical values for q determined by verma and quiroz-ruiz.30 critical values correspond to a particular significance level and represent cutoff values that lead to the acceptance or rejection of a null hypothesis.31 the null hypothesis refers to the position in which there is no statistically significant relationship between two variables.32 the alternate hypothesis would thus be the existence of a relationship between two variables.33 if the calculated value is less than the critical value, the null hypothesis is accepted.34 on the other hand, if the calculated value is greater than the critical value, the null hypothesis is rejected.35 if the null hypothesis is rejected, then the alternate hypothesis must be accepted. here, the null hypothesis can be stated as “the suspected outlier is not an outlier.” the alternate hypothesis can then be stated as “the suspected outlier is an outlier.” therefore if the null hypothesis is rejected. then the suspected outlier is to be considered, in fact, to be an outlier. verma and quiroz-ruiz have calculated the critical value for q for a sample size of 48 and at a 95 percent confidence level to be qcritical = 0.2241.36 although operating at a 99 percent confidence level is a more conservative approach, it increases the likelihood of retaining a value that contains an error.37 operating at a 95 percent confidence level provides a reasonable compromise.38 if the calculated value is greater than the critical value, then the suspected outlier is confirmed to be an outlier. therefore, testing for the suspected outlier of 15,124, the q value was calculated to be qvalue = 0.9581. with q0.9581 > q0.2241, the null hypothesis is rejected and it must be accepted that 15,123 is an outlier. once it is determined with statistical certainty that the suspected outlier is indeed an outlier, it needs to be replaced with the median calculated from all values found in dataset 2. for the case of polymer, the median was calculated to be 27 from all values in table 2. replacing an outlier with the median to accommodate the data has been proven to be quite effective in dealing with outliers by introducing less distortion to that dataset.39 extreme values are therefore replaced with values more consistent with the rest of the data.40 january february march april may june july august september october november december polymer 2009 27 14 35 22 15

is replaced with the median (highlighted in bold). the importance of identifying and accommodating e-resources usage data for the presence of outliers | lamothe 37 table 3 represents the number of full-text articles downloaded for polymer after the outlier had been replaced with the median. the confirmed outlier of 15,123 articles downloaded recorded in october 2010 is replaced with the median of 27, highlighted in bold. this then becomes the accepted value for the number of articles downloaded from polymer in october 2010. the outlier is discarded. the new value of 27 articles downloaded in october 2010 replaces the extreme value of 15,123 in the original 2010 jr1 report (see table 4). this is the final step. january february march april may june july august september october november

polymer’s identified outlier is replaced with the median calculated from table 2 (highlighted in bold). once the first outlier is corrected, the same procedures need to be followed for the other suspected outliers highlighted in table 1. if it is determined that they are outliers, they are replaced with their associated median values. although the steps and calculations used to identify and correct for outliers are relatively simple to follow, it is admittedly a very lengthy and timeconsuming process. but in the end, it is well worth the effort. results and discussion table 5 details the changes in the overall number of articles downloaded from j. n. desmarais library e-journals that resulted from the elimination of outliers. the column titled “recorded downloads” details the number of articles downloaded between 2000 and 2012, inclusively, prior to outlier testing. the column titled “corrected downloads” represents the number of articles downloaded during the same period of time but after the outliers had been positively identified and the data cleaned. the affected values are highlighted in bold. information technology and libraries | june 2014 38 year recorded downloads

data from all available years were tested for outliers. only data recorded in 2010 and 2011 tested positive for outliers. replacing outliers with the median values for those affected journal titles dramatically reduced the total number of downloaded articles (see table 5). between 2007 and 2009, inclusively, the actual number of full-text articles downloaded recorded from the library’s e-journal collection totaled between 731,334 and 725,019 annually (see table 5). the annual average for those three years is 722,132 articles downloaded. but in 2010 that number dramatically increased to 857,360 downloaded articles, which was followed by 869,651 downloaded articles in 2011 (see table 5). the elimination of outliers from the 2010 data resulted in the number of downloads dropping from 857,360 to 757,564, a difference of nearly 99,796 downloads, or 12 percent. similarly, in 2011, the number of articles downloaded decreased from 869,651 to 696,973 once outliers were replaced with median values. this represents a reduction of over 172,678 downloaded articles, or 20 percent. a staggering 20 percent of articles downloaded in 2011 can therefore be considered as erroneous and, in all likelihood, the result of illicit downloading. figure 1 is a graphical representation of the change in the number of articles downloaded before and after the identification of outliers and their replacement by median values. the line “recorded downloads” clearly indicates a surge in usage between 2010 and 2011 with usage returning to levels recorded prior to the 2010 increase. the line “corrected downloads” depicts a very different picture. the plateau in usage that began in 2007 continues through 2012. evidently, the observed spike in usage was artificial and the result of the presence of outliers in certain datasets. if the data had not been tested for outliers, it would have appeared that usage the importance of identifying and accommodating e-resources usage data for the presence of outliers | lamothe 39 had substantially increased in 2010 and it would have been incorrectly assumed that usage was on the rise once more. instead, the corrected data bring usage levels for 2010 and 2011 back in line with the plateau that had begun in 2007 and reflects a more realistic picture of usage rates at laurentian university. figure 1. comparing the recorded number of articles downloaded to the corrected number of articles downloaded over a thirteen-year period. accuracy in any data gathering is always extremely important, but accuracy in e-resource usage levels is critical for academic libraries. academic libraries having e-journal subscription rates based either entirely or partly on usage can be greatly affected if usage numbers have been artificially inflated. it can lead to unnecessary increases in cost. since it was determined that outliers were present only during the period in which the library had found itself under “attack,” it can be assumed that the vast majority, if not all, of the extreme usage values were a result of illegal downloading. it would therefore be a shame to need to pay higher costs because of inappropriate or illegal downloading of licensed content. accurate usage data is also important for academic libraries that integrate usage statistics into their collection development policy for the purpose of justifying the retention or cancellation of a particular subscription. the j. n. desmarais library is such a library. as indicated earlier, if the cost-per-download of a subscription is consistently greater than the cost of an interlibrary loan for three or more years, it is marked for cancellation. at the j. n. desmarais library, the average cost of an interlibrary loan had been previously calculated to be approximately can$15.00.42 therefore, subscriptions recording a “cost-per-download” greater than the can$15.00 target for more than three years can be eliminated from the collection. information technology and libraries | june 2014 40 any artificial increase in the number of downloads would have as result to artificially lower the cost-per-use ratio. this would reinforce the illusion that a particular subscription was used far more than it really was and lead to the false belief that it would be less expensive to retain rather than rely on interlibrary loan services. the true cost-per-use ratio may be far greater than initially calculated. the unnecessary retention of a subscription could prevent the acquisition of another, more relevant, one. for example, after adjusting the number of articles downloaded from sciencedirect in 2011, the cost-per-download ratio increased from can$0.74 to can$1.59, a 53 percent increase. for the j. n. desmarais library, this package was obviously not in jeopardy of being cancelled. but a 53 percent change in the cost-per-use ratio for borderline subscriptions would definitely have been affected. it must also be stated that none of the library’s subscriptions having experienced extreme downloading found themselves in the position of being cancelled after the usage data had been corrected for outliers. regardless, it is important to verify all usage data prior to any data analysis to identify and correct for outliers. once the outlier detection investigation has been completed and any extreme values replaced by the median, there would be no further need to manipulate the data in such a fashion. the identification of outliers is a one-time procedure. the corrected or cleaned datasets would then become the official datasets to be used for any further usage analyses. conclusions outliers can have a dramatic effect on the analysis of any dataset. as demonstrated here, the presence of outliers can lead to the misrepresentation of usage patterns. they can artificially inflate average values and introduce severe distortion to any dataset. fortunately, they are fairly easy to identify and remove. the following steps were used to identify outliers in jr1 countercompliant reports: 1. identify possible outliers: visually inspect the values recorded in a jr1 report dataset (dataset 1) and mark any extreme values. 2. for each suspected outlier identified, take the usage values for the affected e-journal title and incorporate them into a separate blank spreadsheet (dataset 2). incorporate into dataset 2 all other usage values for the affected journal from all available years. it is important that dataset 2 contain only those values for the affected journal. 3. test for the outlier: perform dixon q test on the suspected outlier to confirm or disprove existence of the outlier. 4. if the suspected outlier tests as positive, calculate the median of dataset 2. 5. replace the outlier in dataset 1 with the median calculated from dataset 2. 6. perform steps 1 through 5 for any other suspected outliers in dataset 1. 7. the corrected values in dataset 1 will become the official values and will be used for all subsequent usage data analysis. the importance of identifying and accommodating e-resources usage data for the presence of outliers | lamothe 41 the identification and removal of outliers had a noticeable effect on the usage statistics for j. n. desmarais library’s e-journal collection. outliers represented over 100,000 erroneous downloaded articles in 2010 and nearly 200,000 in 2011. a total of 20 percent of recorded downloads in 2011 were anomalous, and in all likelihood a result of illicit downloading after laurentian university’s ezproxy server was breached. new technologies have made digital content easily available on the web, which has caused serious concern for both publishers43 and institutions of higher learning, which have been experiencing an increase is illicit attacks.44 the history of napster supports the argument that users “will freely steal content when given the opportunity.”45 since web robot traffic will continue to grow in pace with the internet, it is critical that this traffic be factored into the performance and protection of any web servers.46 references 1. victoria j. hodge and jim austin, “a survey of outlier detection

assisted circulation control at health sciences library sunyab 87 jean k. miller: associate health sciences librarian for circulation and dissemination a description of the circulation system which the health scien ces library at the state university of new york at buffalo has been using since october 1970. features of the system include automatic production of overdue, fin e, and billing notices; notices for call-in of requested books; and book availability notices. remote operation and processing on the ibm 360/40 and cdc 6400 computer are accomplished via the administrative terminal system (ats) and terminal job entry (t]e). th e system provides information for management of the collection and improved service to the user. introduction the health sciences library of the state university of new york at buffalo (sunyab) serves the teaching, research, and clinical programs of the five schools of health sciences at the university-medicine, dentistry, pharmacy, nursing, health related professions-as well as the department of biology. it is the biomedical resource library for the five teaching hospitals affiliated with sunyab and for the health professionals within the nine counties of the lakes area regional medical program. service demands had increased steadily since 1961 with the incorporation of the university within the state of new york this was apparent in the circulation department where statistics indicated a 21 percent increase in the circulation of materials between fy 1967/ 68 and 1968/ 69. the circulation system in use was inefficient and time-consuming for both the user and the clerical staff. the user was required to fill out a charge card for each book, giving his name, address, and status; and the title, author, year of publication, volume, copy number, and call number of the book. the card 88 journal of library automation vol. 5/ 2 june , 1972 was stamped with the due date and filed alphabetically by main entry. problems resulted from illegible handwriting, selection of incorrect main entry, and incorrect filing. control of library materials was inadequate. the system to be described was adopted following consideration of the requirements of an effective system of circulation control and of the resources available to the library. planning for the development and implementation of the automated circulation system began in the fall of 1969. funding was provided by a medical library resource grant and the office of the provost of health sciences of sunyab. system design began in february 1970; programming was accomplished during june and july; implementation started in august; and the system was operational in october 1970. costs of operation have been provided by the university libraries of sunyab since april 1971. computer facilities the health sciences library shares the facilities provided by the department of computer services on campus. the current installation is an ibm 360/40 h with an eight-disk drive 2319 unit, six magnetic tape devices, card read and punch unit, and a 1100 line-per-minute printer. it includes a 2703 telecommunications unit supporting forty 2741 terminals and a 2701 unit with parallel data adapter unit interfacing a channel-to-channel adapter to a cdc 6400 computer. the ibm operating system, scope 3.2.0 version 1.1, is used. processing the library's circulation system was designed to use the administrative terminal system (a ts) and terminal job entry ( tje) for remote operation and processing on the ibm 360/40 and cdc 6400 computers. programs are written in fortran for cdc 6400-6500-6600 (version 2.3). the program modules comprising the circulation system require from lk to 60k and from 0 to 2 tape units for processing. ats documents are used rather than punched card decks as program and data input media. the system incorporates several large data bases which are updated at regular intervals. a file of current circulation transactions ( 80 characters per record) is mahltained on both magnetic tape and in a ts storage. this file is merged daily with new transactions. names and addresses of university personnel and students are maintained on magnetic tape. a file of inactive circulation records (50 characters per record) is also maintained on tape. other smaller files are stored in ats and are updated daily and/ or weekly. no permanent disk storage is used. input of data and programs is made from the ibm 2741 terminal located in the circulation office of the library. data are entered daily by the clerical staff via the ats terminal. storage, retrieval, and text editing are performed as required. processing of data is initiated by the library staff. a properly sequenced assemblage of ats documents consisting of data and procomputer assisted circulation control/miller 89 gramming instructions ( tje input file) is input from the ibm 27 41 terminal. this input file is submitted through tje for execution on the cdc 6400 computer. the data are processed in accordance with the specific job command entered at the terminal. after processing, the output is stored as a single ats document. in some instances, the clerical staff divides the ats stored output into discrete output files for storage and subsequent use. selected segments of the output (notices, save lists, etc.) are produced in hard copy format and delivered to the library by the computer center (figure 1). hsccirc system the health sciences library circulation system ( hsccirc) provides: 1. a file (query file) of all monographs off the shelves which includes a record of: a. books charged out. b . books on interlibrary loan. c. books on reserve. d . books at the bindery. e. books on the "hold shelf'' which have been returned upon the request of another patron. f. books on the "new book shelf." g. books which have been declared lost and are in the process of being replaced. 2. overdue notices to all borrowers. 3. billing notices to students for those books not returned after a second overdue has been sent. 4. a file (fine file) indicating the amount owed by individual students for overdues. 5. fine notices to students if an overdue book is returned but the fine is not paid. 6. notices to users having books requested by other patrons. 7. hold shelf notices alerting library personnel to those books which have been reserved for library pat rons. 8. book availability notices to users who have made "save" requests. 9. a file (history file) containing records of inactive transactions. 10. daily and cumulative (fiscal year-to-date) statistics of the transactions. the foregoing lists the information which the system provides on a routine basis. other modules of the system permit access to additional information as required. for example, lists may be prepared of books currently in circulation to interlibrary loan, on reserve, or at the bindery. these lists are used by the staff involved in processing these materials and may be updated at their request. 90 journal of library automation vol. .5 j 2 jun e, 1972 query file processing query file (ats) 8 8 ,.-----'--'---" processing fine unpaid fine file file

special run sequences lists (ill . reserve bindery) 92 journal of library automation vol. .5/ 2 june, 1972 the history file is analyzed quarterly. the analysis provides a statistical breakdown, by user categories, of the transactions which occurred since the last analysis. the total number of charges, renewals, and save requests for each of the five user categories are tallied. the call numbers of the books borrowed by members of each user category are listed. multiple charges of the same book are incremented and recorded. this information on book usage and borrowing patterns assists in library management decisions. it is possible to identify high usage of specific volumes or subject areas and to determine whether the demand is from the faculty, staff, or graduate or undergraduate student body. records of heavy demand and multiple save requests aid in decisions to purchase additional copies of a monograph. at the end of each semester, faculty /staff letters are prepared and mailed. each notice lists the call number and due date for overdue books currently charged to the faculty or staff member. the notice requests return of the book( s) before the beginning of the next semester. statistics generated by the system (figure 2) are used in the preparation of monthly, quarterly, and annual reports. they have been used as a basis for decisions on policy such as that resulting in a change in the length of the circulation period in april 1971. subsequent statistics have been used to evaluate such changes. in addition, the system permits rapid, easy consultation of the query file to detect the location of any book off the shelves. this is accomplished through use of the printed query file (figure 3) which is arranged in call number sequence. it contains one line

if the book becomes overdue, a second line of information is automatically generated indicating the overdue status of the book. a two-digit transaction code defines the status. the transaction code is entered as part of the input (as code 10 when charging a book); or it is generated by the system, as occurs when a book becomes overdue and initial and subsequent overdue, billing, and/or fine notices are produced (code 51,52,53,54). this same information may be obtained through on-line query of the circulation file from the ibm 2741 terminal during the hours of operation of ats. access to the query file is either by call number of the book or identification number of the user. the latter is used when producing lists of items out on loan to a borrower and in detecting delinquent borrowers. 94 journal of library automation vol. 5/2 june, 1972 overview comparison of statistics between fy 1969/70 and fy 1971/72 showed a 12 percent increase in circulation. during the same period there was a 61 percent increase in the number of people using the library. the circulation department has been able to handle the increased workload more efficiently because of the automated system. a decrease in clerical time required for carrying out the tasks of the department has been realized. the circulation records are now updated five times per week and notices are issued promptly. previously, updating was possible only once in every seven to ten days. service to the user is much faster and more accurate in charging books and in providing information on this status. control of items loaned to users is more effective. information for management of the collection and provision of improved service is available. system disadvantages are related to the mode of data input and lack of author and title information on records. transcription errors occur during manual capture of data at the time the transaction occurs and when the data are entered by the clerical staff from the terminal. correction of errors requires rekeying and reentry of the corrected data for reprocessing. this increases cost in terms of personnel time and equipment use. author and title information is not provided in the query file or on notices sent to users. this is an inconvenience to the user and requires checking of the shelf list by library personnel to provide the information when required. these potential disadvantages were recognized at the time the system was planned. however, they were not considered serious drawbacks. the decision was made to adopt the system and, when additional funds were forthcoming, to provide machine readable input and add author and title information to the records. costs the cost of the system during its first year of operation was $10,590.65. this included monthly charges for rental of equipment, use of ats, storage of records, computer time, and print costs. ibm 27 41 terminal (including phone line) a ts sign on time ats storage computer time and print costs total $1082.86 1042.08 3187.24 5278.47 $10,590.65 unit cost figures are imperfect, but over 69,000 transactions were processed and over 20,000 notices generated at an average unit cost of 11.6 cents. clerical time is not included in this figure. the number of clerical assistants remained constant although, as noted, all phases of the work of the circulation department increased. computer assisted circulation contmljmiller 95 future development in the future, the library hopes to be able to take greater advantage of the on-line query capability of the present system. additional ibm 27 41 terminals at selected locations in the library could provide instantaneous file query. while non-routine queries are made on-line, the library now uses printed listings for most routine queries. the installation of automatic data input devices, such as ibm 1030 equipment, would permit reading of coded book cards and patron identification cards with direct transmission of data to ats storage. the hardware and software modification required to implement this additional capability is technically feasible and not financially prohibitive. the present system is to be installed soon in another library on the sunyab campus. implementation should require only minimal software modifications to identify and keep separate the records of the other library. adoption is simplified because of the fact that book cards are not required and that the circulation file consists only of charged materials and not a record of complete library holdings. acknowledgments the following individuals

this is the last issue of the journal of library automation. the first issue appeared in march 1968, just shortly after this editor had graduated from library school. under the editorships of frederick g. kilgour and susan k. martin, ]ola established itself as a major source of information about developments in library automation. this is also the last issue of the first volume produced by a new editorial board. the current editors are especially indebted to eileen mahoney of ala's central publication unit, whose experience, patience, and wise counsel contributed materially to making this last volume one we are all proud of. hello ital please welcome volume l , number l of information technology and libraries when its bright new face appears on your doorstep in march. it will look very familiar to you. the new name reflects many of the shifts in emphasis that have gradually been introduced in recent years as changing technologies have encouraged a broadening of lola's original scope. we plan to introduce some minor changes to increase it al's utility, but see these as evolutionary. \.ye continue to solicit comments and suggestions on how the journal can better serve your needs. sychronicity in our september issue, we initiated a new section , " reports and working papers," in which we reproduce documents we believe deserve a wider readership than their original distribution. w e were amused to note a similar innovation in the august bulletin of the american society for information science. we would welcome comments on the usefulness (or wastefulness) of the new section. standard.s standards continue to be a major concern in our field. w e hope those of you involved with acquisitions systems will find the communications by sandy paul and jim long in this issue useful. we encourage you to participate in standards development efforts when possible. please t ry to use developed standards whenever they are applicable to your work. the isbn , san (standard

in the dark: diagnosing slowness in library response time | brown-sica 29 margaret brown-sicatutorial playing tag in the dark: diagnosing slowness in library response time in this article the author explores how the systems department at the auraria library (which serves more than thirty thousand primarily commuting students at the university of colorado–denver, the metropolitan state college of denver, and the community college of denver) diagnosed and analyzed slow response time when querying proprietary databases. issues examined include vendor issues, proxy issues, library network hardware, and bandwidth and network traffic. w hy is everything so slow?” this is the question that library systems departments often have the most trouble answering. it is also easy to dismiss because it is often the fault of factors beyond the control of library staff. what usually prompts these questions are the experiences of the reference librarians. when these librarians are trying to help students at the reference desk, it is very frustrating when databases seem to respond to queries slowly, files take forever to load onto the computer screen, and all the while the line in front of the desk get continues to grow. or the library gets calls from students using databases and the catalog from their homes who complain that searching library resources takes too long, and that they are getting frustrated and using google instead. this question is so painful because libraries spend so much of their shrinking budgets on high quality information in the form of expensive proprietary databases, and it is all wasted if users have trouble using them. in this case the problem seemed to be how slow the process of searching for information and downloading documents from databases was. for lack of a better term, the auraria library called this the “response time” problem. this article will discuss the various ways the systems (technology) department of the auraria library, which serves the university of colorado–denver, metropolitan state college of denver, and the community college of denver, tried to identify problems and improve database response time. the systems department defined “response time” as the time it took for a person to send a query from a computer at home or in the library to a proprietary information database and receive a response back, or how long it took to load a selected fulltext article from a database. when a customer sets out to use a database in the library, the query to the database could be slowed down by many different factors. the first is the proxy, in our case innovative interfaces’ inc. web access management (iii wam), a product that authenticates the user via the iii api (application program interface) product. to do this the query travels over network hardware, switches, and wires to the iii server and back again. then the query goes to the database’s server, which may be almost anywhere in the world. hardware problems at the database vendor’s end can affect this transfer. in the case of auraria library this transfer can be influenced by traffic on the library’s network, the university’s network, and any other place in between. this could also be hampered by the amount of memory in the computer where the query originates, by the amount of tasks being performed by that computer, etc. the bandwidth of the network and its speed can also have an effect. basically, the bottlenecks needed to be found and fixed. bottlenecks are described by webopedia as “the delay in transmission of data through the circuits of a computer’s microprocessor or over a tcp/ip network. the delay typically occurs when a system’s bandwidth cannot support the amount of information being relayed at the speed it is being processed. there are, however, many factors that can create a bottleneck in a system.”1 literature review there is not a lot on database response slowness in library literature, probably because the issue overlaps with computer science and really is not one problem but a possibility of one of several problems. the issue is figuring out where the problem lies. gerhan and mutula examined technical reasons for network slowness, performing bandwidth testing at a library in botswana and one in the united states using the same computer, and giving several suggestions for testing, fixing technical problems, and issues to examine. gerhan and mutula concluded that bandwidth and insufficient network infrastructure were the main culprits in their situation. they studied both bandwidth and bandwidth “squeeze.” looking for the bandwidth “squeeze” means looking along the internet’s “journey of many stages through routers and exchange points, each successively farther removed from the user.”2 bandwidth bottlenecks could occur at any one or more of those stages in the query’s transmission. the following four sections parse that lengthy pathway and examine how each may contribute to delays.

200830 information technology and libraries | december 2008 queries, load balancing, and how they function.3 bertot and mcclure’s “assessing sufficiency and quality of bandwidth for public libraries” is based on data collected as part of the 2006 public libraries and the internet study and provides a very straightforward approach for checking specific areas for problems.4 it outlines why basic data such as bandwidth readings may not give the complete picture. it also gives a nice outline of factors involved such as local settings and parameters, ultimate connectivity path, application resource needs, and protocol priority. azuma, okamoto, hasegawa, and masayuki’s “design, implementation and evaluation of resource management system for internet servers” was very helpful in understanding the role and function of proxy servers and problems they can present.5 vendor issues this is a very thorny topic because it is out of the library’s control, and also because the library has so many databases. the systems department asked the reference staff to send reports of problems listing the type of activity attempted, time and dates, the names of the database, the problem and any error messages encountered. a few that seemed to be the slowest were selected for special examination. one vendor worked extensively with the library and in the end it was believed that there were problems at their end in load balancing, which eventually seemed to be fixed. that company was in the middle of a merger and that may have also been an issue. we also noted that a database that uses very large image files, artstor, was hard to use because it was so slow. this company sent the library an application that simulated the databases’ use and was supposed to test to see if bandwidth at auraria library was sufficient for that database. according to the test, it was. databases that consistently were perceived as the slowest were those that had the largest documents and pictures, such as those that used primarily pdfs and visual material. this, with the results of the testing, pointed to a problem independent of vendor issues. bandwidth and network traffic the systems department decided to do bandwidth testing on the library’s public and staff computers after reading gerhan and mutula’s article about the university of botswana. the general perception is that bandwidth is often the primary problem in network slowness, as well as the problems with databases that use larger files. several of the computers were tested in several successive days during what is usually the busiest time for the network, between noon and 2 p.m. the results were good, averaging about 3000 kilobytes per second (kbps). for this test we used the cnet bandwidth meter, which downloads an image to your computer, measures the time of the download, and compares it to the maximum speeds offered by other internet service providers.6 there are several bandwidth meters available on the internet. when the network administrator checked the switches for network traffic, they showed low traffic, almost always less than 20 percent of capacity. this was confusing: if the problem was neither with the bandwidth nor the vendors, what was causing the slow network performance? one of the university network administrators was consulted to see if any factor in their sphere could be having an effect on our network. we knew that the main university network had implemented a bandwidth shaper to regulate bandwidth. “these devices limit bandwidth . . . by greedy applications, guarantee minimum throughput for users, groups or protocols, and better utilize widearea connections by smoothing out bursty traffic.”7 it was thought that perhaps this might be incorrectly prioritizing some of the library’s traffic. this was a dead end, though—the network administrators had stopped using the device. if the bandwidth was good and the traffic was manageable, then the problem appeared to not be at the library. however, according to bertot and mcclure, the bandwidth question is complex because typically an arbitrary number describes the number of kbps used to define “broadband.” . . . such arbitrary definitions to describe bandwidth sufficiency are generally not useful. the federal communications commission (fcc), for example, uses the term “high speed” for connections of 200kbps in at least one direction. there are three problematic issues with this definition: 1. it specifies unidirectional bandwidth, meaning that a 200kbps download, but a much slower upload (e.g., 56kbps) would fit this definition; 2. regardless of direction, bandwidth of 200kbps is neither high speed nor does it allow for a range of internet-based applications and services. this inadequacy will increase significantly as internet-based applications continue to demand more bandwidth to operate properly. 3. the definition is in the context of broadband to the single user or household, and does not take into consideration the demands of a high-use multiple-workstation public-access context.8 proxy issues auraria library uses the iii wam proxy server product. there were several things that pointed to the introducing zoomify image | smith 31playing tag in the dark: diagnosing slowness in library response time | brown-sica 31 proxy being an issue. one was that the systems department had been experimenting with invoking the proxy in the library building in order to collect more accurate statistics and found that complaints about speed seemed to have started around the same time as this experiment. but if the bandwidth was not showing inadequacy and the traffic was light, why was this happening? the answer is better explained by azuma et al.: needless to say, busy web servers must have many simultaneous http sessions, and server throughput is degraded when effective resource management is not considered, even with large network capacity. web proxy servers must also accommodate a large number of tcp connections, since they are usually prepared by isps (internet service providers) for their customers. furthermore, proxy servers must handle both upward tcp connections (from proxy server to web servers) and downward tcp connections (from client hosts to proxy server). hence, the proxy server becomes a likely spot for bottlenecks to occur during web document transfers, even when the bandwidth of the network and web server performance are adequate.9 testing was done from on campus and off campus, with and without using the proxy server. the results showed that the connection was faster without the proxy. when testing was done from the health sciences library at the university of colorado with the same type of server and proxy, the response time was much faster. the difference between auraria library and the other library is that the community auraria library serves (the community college of denver, metropolitan state college, and the university of colorado–denver) has a much larger user population who overwhelmingly use databases from home, therefore taxing the proxy server. the other library belonged to a smaller campus, but the hardware was the same. the proxy was immediately dropped for on-campus users, and that resulted in some responsetime improvements. a conference call was set up with the proxy vendor to determine if improvements in response time might be attained by changing from a proxy server to ldap (lightweight directory access protocol) authentication. the response given was that although there might be other benefits, increased response time was not one of them. library network hardware it was evident that the biggest bottleneck was the proxy, so the systems department decided to take a closer look at iii’s hardware. the switch that regulated traffic between the network and the server that houses our integrated library system, part of which is the proxy server, was discovered to have been set at “halfduplex.” half-duplex refers to the transmission of data in just one direction at a time. for example, a walkie-talkie is a half-duplex device because only one party can talk at a time. in contrast, a telephone is a full-duplex device because both parties can talk simultaneously. duplex modes often are used in reference to network data transmissions. some modems contain a switch that lets you select between halfduplex and full-duplex modes. the correct choice depends on which program you are using to transmit data through the modem.10 when this setting was changed to full duplex response time increased. there was also concern that this switch had not been functioning as well as it could. the switch was replaced, and this also improved response time. in addition, the old server purchased through iii was a generic server that had specifications based on the demands of the ils software and didn’t into consideration the amount of traffic going to the proxy server. auraria library, which serves a campus of more than thirty thousand full-time equivalent students, is a library with one of the largest commuter student populations in the country. a new server had been scheduled to be purchased in the near future, so a call was made to the ils vendor to talk about our hypothesis and requirements. the vendor agreed that the library should change the specification on the new server to make sure it served the library’s unique demands. a server will be purchased with increased memory and a second processor to hopefully keep these problems from happening again in the next few years. also, the cabling between the switch and the server was changed to greater facilitate heavy traffic. conclusion although it is sometimes a daunting task to try to discover where problems occur in the library’s database response time because there are so many contributing factors and because librarians often do not feel that they have enough technical knowledge to analyze such problems, there are certain things that can be examined and analyzed. it is important to look at how each library is unique and may be inadequately served by current bandwidth and hardware configurations. it is also important not to be intimidated by computer science literature and to trust patterns of reported problems. the auraria library systems department was fortunate to also be able to compare problems with colleagues at other libraries and test in those libraries, which revealed issues that were unique and therefore most likely due to a problem at the library end. it is important to keep learning about how 32 information technology and libraries | december 200832 information technology and libraries | december 2008 your system functions and to try to diagnose the problem by slowly looking at one piece at a time. though no one ever seems to be completely satisfied with the speed of their network, the employees of auraria library, especially those who work with the public, have been pleased with the increased speed they are experiencing when using proprietary databases. having improved on the responsetime speed issue, other problems that are not caused by the proxy hardware have been illuminated, such as browser configuration, which may be hampering certain databases—something that had been attributed to the network. references 1.

brzustowicz article entitled “from chatgpt to catgpt” in your sept. 2023 issue sparked much discussion in several online cataloging communities, much of it consisting of amazement that such a poorly designed experiment could have made it through the peer review process at ital. the structure of the article demonstrates a clear misunderstanding of what generative artificial intelligence [ai] even is—from asking the program itself questions regarding its training data to saying that the program follows cataloging rules. starting from a flawed premise leads to flawed results. so what is generative ai? generative ai programs such as chatgpt are language-learning models, a subclass of neural network. neural networks are machine-learning algorithms whose structures are modeled on the structure of the human brain. they solve problems through trial and error and, with the increasing affordability of cloud computing and processing power, can process vast amounts of training data and draw conclusions from it. this is an extremely useful tool. as janelle shane says, “they’re great at matching patterns and finding subtle trends in highly multivariate data. crucially, they make progress towards their goal even if the programmer doesn’t know how to solve the problem ahead of time.”1 how does this apply to chatgpt? generative text ai are essentially extremely advanced predictive text generators. “chatgpt is always fundamentally trying … to produce a ‘reasonable continuation’ of whatever text it’s got so far, where by ‘reasonable’ we mean ‘what one might expect someone to write after seeing what people have written on billions of webpages, etc.’”2 because it is trained on a lot of natural language materials, it can produce very convincing sentences that seem to carry meaning. openai’s own faq explains it in this way: chatgpt is called “a language model trained to produce text.” in other words, it “uses human demonstrations and preference comparisons to guide the model toward desired behavior.” “these models were trained on vast amounts of data from the internet written by humans, including conversations, so the responses it provides may sound human-like.” they warn, however, that, “chatgpt is not connected to the internet, and it can occasionally produce incorrect answers. it has limited knowledge of world and events after 2021 and may also occasionally produce harmful instructions or biased content,” and “chatgpt will occasionally make up facts or ‘“hallucinate’” outputs. if you find an answer is unrelated, please provide that feedback by using the ‘“thumbs down’” button.”3 chatgpt does not think for itself. it is not self-aware and cannot meaningfully answer questions about itself. it also cannot be trained like a human because it doesn’t “understand” anything. it repeats back information and data based on statistical probabilities. even the people who created chatgpt, in their own faq, warn users that it can give incorrect or made-up answers that are unrelated to the questions and input that a person gives it. information technology and libraries december 2023 letter to the editors 2 amram, malabud, and hollingsworth furthermore, it is baffling that brzustowicz claimed that chatgpt was able to generate accurate records when even a cursory glance at the author’s own appended data shows multiple mismatches between generated records and existing records. however, we have taken more than a cursory glance, and we believe that it is important to really dig into all the ways in which chatgpt fails at even basic cataloging tasks. let’s take this item by item. the first example the author puts forth consists of a chatgpt record and a professional cataloger’s record for “the 1996 reprint of interview with the vampire by anne rice using rda.”4 this first example contains several critical informational differences between the two records. starting at the top, the 020 fields, representing the isbn of the work, contain different numbers. searching for the isbn listed in the chatgpt record in oclc connexion brings up many records from various years, published by ballantine books, but no record from 1996. a search for the isbn from the professional record also brings up many records, but published by knopf, not ballantine books, and there is a 1996 edition featured. additionally, the isbn for the chatgpt record is labeled as a paperback edition, and the isbn for the professional record is labeled as a hardback edition. the 040 field, which records the source of the cataloging, in the chatgpt record features the code dlc, which is the code for the library of congress. this is incorrect: this is not a library of congress-created record, but one generated by chatgpt. (this false attribution is common to all of the chatgpt records save one.) additionally, the 040 shows that chatgpt did not generate an rda record, as it is missing the subfield e which would indicate the use of rda. continuing down the record, the 250 field in the professional record holds an edition statement, while the chatgpt record has no 250 field at all. the author did not describe which edition they were basing their search off of, so it is difficult to proclaim one as correct for the item in hand and the other incorrect, but either way, an edition statement is a core element of a descriptive record, and the difference between these two records is not encouraging. as can be surmised from the isbn differences, the publisher featured in the 260 $b subfield differs between the chatgpt record, which attributes it to ballantine books, and the professional record, which attributes it to knopf. this alone is deeply worrying; the publisher is such a vital piece of information for identifying which record to apply that chatgpt’s failure to provide an accurate value invalidates the record. again, we do not know which company published the item the author had in hand, but as there is no 1996 ballantine edition represented in oclc at the time of this writing, it is not hard to see the inaccuracy. even more glaringly, the 300 field, which contains the extent, contains both a significantly different page count value (372 pages from chatgpt and 340 pages from the professional record), but also physical size of the book (18 cm versus 22 cm). the 300 field in the chatgpt record also has a period at the end of the field, which is incorrect (the 300 only ends in a mark of punctuation when there is a series statement, which there is not in either record). the next significant difference between the two records comes in the subject headings. the chatgpt record only has two 650 fields (each, interestingly and incorrectly, repeated twice), and they are very basic, only “vampires $v fiction” and “horror tales.” the professional record, on the information technology and libraries december 2023 letter to the editors 3 amram, malabud, and hollingsworth other hand, has three distinct subject headings, one including the established 600 for the main character of the work, and a library of congress genre/form terms (lcgft) term, bringing the total subject descriptive fields up to four (double the amount of chatgpt, and more useful ones). the records for the album low by david bowie contain similar discrepancies. the chatgpt record has no place of publication or publisher, the title contains a deprecated subfield h, and the 336, which represents the content type, is incorrect (“notated music” indicates that the music is written down and “intended to be perceived visually,”5 whereas the professional record correctly has “performed music” in the 336, which is correct for an album). additionally, the professional record contains a track listing, which the chatgpt record lacks, and more accurate subject headings. the chatgpt record for the german translation of paulo freire’s pedagogy of the oppressed in the original article has been compared to a dutch-language record, not an english-language record, and so we will not attempt to analyze the differences. we will say, however, that the 240 field, meant for the uniform title, in the chatgpt record reads “pedagogy of the oppressed. $l german,” when it should use the original title of the work, which was in portuguese, and should instead read “pedagogia do oprimido. $l german.” furthermore, the call number in the 050 field has a second indicator 0, which indicates that it was generated by the library of congress, which it was not, and is also incorrect—paulo freire’s works are generally classed into lb880.f73, and the classification number used by chatgpt, lb875, is used for american educators only. there is also an 042 field claiming that the record is a pccgenerated record, which is false. the record attributed to chatgpt for cixin liu’s the three body problem is character-forcharacter identical to the record attributed to a professional cataloger. one wonders whether there was a copy-paste error, especially given that the text of the article claims that the chatgpt record did have differences from the professional record.6 as we do not have a copy of mood rings’ “pathos y lagrimas” in hand, we cannot assess the accuracy of the chatgpt record. that being said, this record has an oclc number in the 035 field, which, when searched, has already been assigned to an open-access electronic resource record created in 2018. (the only other example record in the original article with an 035 was also a chatgpt record, for the german translation of pedagogy of the oppressed, and the oclc number was also already assigned elsewhere.) we have gone into some detail regarding the cataloging fields and specifications in the above analysis. this was a deliberate choice. the author of the original article gives their job title as instruction and outreach librarian. we cannot speak to their cataloging experience, or lack thereof, but anyone trained in cataloging practices would have caught at least some of the above errors in chatgpt’s output on an initial read. there is more to cataloging than the look of the record, or the existence of certain fields. just because a record has a title field, a publication information field, and a handful of subject headings does not make it an accurate record, or useful to the researcher in any meaningful way. cataloging is a precise, detail-oriented practice, as it must be in order to distill the contents of a work into a single, searchable record. the original article is careful to mention that review of chatgpt records is needed before they can be loaded into a library catalog. rather than starting with a blank slate which can be filled in from information technology and libraries december 2023 letter to the editors 4 amram, malabud, and hollingsworth the start by a trained cataloger with the item in hand, the author would have us start with an error-riddled tangle of probability-predicted words and spend our time instead unpicking the mistakes of a generative language model. chatgpt cannot understand the rules of marc or rda, as a human can. all it can do is generate predicted text strings. yes, cataloging takes time, care, and attention to do correctly. this does not mean that automation would make the process easier or faster; instead, as we have seen here, attempting to automate the process only slows things down. rather than proving that chatgpt is a useful, accurate tool for generating records, the article has instead proven that chatgpt cannot be a successful replacement for a trained, professional cataloger. we recognize that artificial intelligence is the hot new thing in a wide range of industries, including in librarianship, but it would behoove a respected scholarly journal to do its due diligence, rather than jump on the bandwagon. sincerely, tess amram special materials and continuing resources cataloging librarian university of colorado boulder tess.amram@colorado.edu robin goodfellow malamud cataloger and classifier i boston public library rmalamud@bpl.org cheryl hollingsworth cataloguing librarian university of dallas chollingsworth@udallas.edu notes 1 janelle shane, “neural networks, explained,” physics world, last modified july 9, 2018, https://physicsworld.com/a/neural-networks-explained/. 2 stephen wolfram, “what is chatgpt doing … and why does it work?”, stephen wolfram writings, last modified february 14, 2023, https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-itwork/. 3 natalie, “what is chatgpt?”, openai help center, accessed october 27, 2023, https://help.openai.com/en/articles/6783457-what-is-chatgpt. 4 richard brzustowicz, “from chatgpt to catgpt,” information technology and libraries 42, no. 3 (september 2023): 2, https://doi.org/10.5860/ital.v42i3.16295. 5 “rda registry | vocabulary,” american library association, accessed october 27, 2023, https://www.rdaregistry.info/termlist/rdacontenttype/. 6 brzustowicz, “catgpt,” 3. mailto:tess.amram@colorado.edu mailto:rmalamud@bpl.org mailto:chollingsworth@udallas.edu https://physicsworld.com/a/neural-networks-explained/ https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/ https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/ https://help.openai.com/en/articles/6783457-what-is-chatgpt https://doi.org/10.5860/ital.v42i3.16295 https://www.rdaregistry.info/termlist/rdacontenttype/ antelman 128 information technology and libraries | september 2006 article title: subtitle in same font author name and second author author id box for 2 column layout library catalogs have represented stagnant technology for close to twenty years. moving toward a next-generation catalog, north carolina state university (ncsu) libraries purchased endeca’s information access platform to give its users relevance-ranked keyword search results and to leverage the rich metadata trapped in the marc record to enhance collection browsing. this paper discusses the new functionality that has been enabled, the implementation process and system architecture, assessment of the new catalog’s performance, and future directions. editor’s note: this article was submitted in honor of the fortieth anniversaries of lita and ital. t he promise of online catalogs has never been realized. for more than a decade, the profession either turned a blind eye to problems with the catalog or accepted that it is powerless to fix them. online catalogs were, once upon a time, “the most widely-available retrieval system and the first that many people encounter.”1 needless to say, that is no longer the case. libraries cannot force users into those “closed,” “rigid,” and “intricate” online catalogs.2 as a result, the catalog has become for many students a call-number lookup system, with resource discovery happening elsewhere. yet, while the catalog is only one of many discovery tools, covering a proportionately narrower spectrum of information resources than a decade ago, it is still a core library service and the only tool for accessing and using library book collections. in recognition of the severity of the catalog problem, particularly in the area of keyword searching, and seeing that integrated library system (ils) vendors were not addressing it, the north carolina state university (ncsu) libraries elected to replace its keyword search engine with software developed for major commercial web sites. the software, endeca’s information access platform (iap), offers state-of-the-art retrieval technologies. ฀ early online catalogs larson and large and beheshti summarize an extensive body of literature on online public access catalogs (opacs) and related information-retrieval topics through 1997.3 the literature has tapered off since then; however, as promising innovations failed to be realized in commercial systems, mainstream opac technology stabilized, and the library community’s collective attention was turned to the web. first generation online catalogs (1960s and 1970s) provided the same access points as the card catalog, dropping the user into a pre-coordinate index.4 the first online catalogs, byproducts of automating circulation functions, were “intended to bring a generation of library users familiar with card catalogs into the online world.”5 the expectation was that most users were interested in known-item searching.6 with the second generation of online catalogs came keyword or post-coordinate (boolean) searching. while systems based on boolean algebra represented an advance over those that preceded them, boolean is still a retrieval technique designed for trained and experienced searchers. (twenty years ago, salton wrote, “[t]he conventional boolean retrieval methodology is not well adapted to the information retrieval task.”7) boolean systems were, however, simple to implement and economical in their storage and processing requirements, important at that time.8 soon after the euphoria of combining free-text terms across records wore off, the library community recognized that the major problem with firstand second-generation catalogs was the difficulty of searching by subject.9 ฀ the “next-generation” catalog by the early 1980s, thinking turned to next-generation catalog features.10 out of this surge of interest in improving online catalogs emerged a number of experimental catalogs that incorporated advanced search and matching techniques developed by researchers in information retrieval. they typically did not rely on exact match (boolean) but used partial-match techniques (probabilistic and vector-based). since probabilistic and vector-based models were first worked out on document collections, not collections of marc records, adaptations were made to the models.11 these prototype systems included okapi, which implemented search trees, and cheshire ii, which refined probabilistic retrieval algorithms for online catalogs.12 it is particularly sobering to revisit one system that was developed between 1979 and 1983. the cite catalog, developed at the national library of medicine, incorporated many of the features of the endeca-powered catalog, including suggesting (mesh) subject headings, correcting spelling errors, stemming, as well as even more advanced features, such as term weighting, keyword suggestion, and “find similar.”13 toward a twenty-first century library catalog kristin antelman, emily lynema, and andrew k. pace kristin antelman (kristen_antelman@ncsu.edu), emily lynema (emily_lynema@ncsu.edu), and andrew k. pace (andrew_pace@ncsu.edu) are respectively associate director for the digital library, systems librarian for digital projects, and head, information technology, at the north carolina state university libraries, raleigh. toward a twenty-first-century library catalog | antelman, lynema, and pace 129 ฀ where are we now? as belkin and croft noted in 1987, “there is a disquieting disparity between the results of research on ir techniques . . . and the status of operational ir systems.”14 two decades later, libraries are no better off: all major ils vendors are still marketing catalogs that represent secondgeneration functionality. despite between-record linking made possible by migrating catalogs to web interfaces, the underlying indexes and exact-match boolean search remain unchanged. it can no longer be said that more sophisticated approaches to searching are too expensive computationally; they may, however, to be too expensive to introduce into legacy systems from a business perspective. ฀ the endeca-powered catalog coupled with the relative paucity of current literature on next-generation online catalogs is a scarcity of library industry interfaces from which to draw inspiration, rlg’s red light green and oclc’s fictionfinder being notable exceptions. in june 2004, library automation vendor tlc announced a partnership with endeca technologies for joint sales, marketing, technology, and product development of the company’s iap software. this search software underlies the web sites of companies such as wal-mart, barnes and noble, ibm, and home depot. ncsu libraries acquired endeca’s iap software in may 2005, started implementation in august, and deployed the new catalog in january 2006. several organizational and cultural factors contributed to making this project possible. of significance was an ongoing administrative commitment to fund digitallibrary innovation, including projects that involve some risk. library staff share this feeling that calculated risks are opportunities to improve the library as well as to open up new challenges in their own jobs. critically, they also believe that not all issues, particularly “edge cases,” (i.e., rarely occurring scenarios) must be resolved before releasing a new service. finally, it was important that the managers who controlled access to programming and other resources were also the project leaders and drivers of the collective urgency to solve the underlying problem. all these factors also contributed to making possible a five-month implementation timeline. functionality the principle functionality gained by implementing an advanced search-and-navigation technology such as the endeca iap falls in three main areas: relevance-ranked results, new browse capabilities, and improved subject access. most ilss, including ncsu’s former catalog, presented keyword results to users in one order: last-in, first-out (i.e., system sort), while browsing within keyword result sets was limited to the links within individual records. ฀ searching and relevance ranking of results inhabiting the catalog search landscape now, somewhere between a secondand third-generation catalog, is endeca’s mdex engine, which is capable of both boolean and limited partial-match retrieval. queries submitted to endeca can use one of several matching techniques (e.g., matchall, matchany, matchboolean, matchallpartial). the current ncsu implementation primarily uses the “matchall” technique for keyword searching, an implied and technique that requires that all search terms (or their spellcorrected, truncated form) entered by the user occur in the result. the user is not required to enter boolean operators for this type of search; in fact, these terms are discarded as stopwords. the “matchboolean” technique continues to support true boolean queries with standard operators; access to this functionality is provided through advanced search options. although classic information retrieval research tends to associate relevance ranking with probabilistic or vector-based retrieval techniques, endeca includes a suite of relevance ranking options that can be applied to booleantype searches (i.e., implied and/or). these individual modules are combined and prioritized according to customer specifications to form an overall relevance ranking strategy, or algorithm. each search index created in the endeca software can be assigned a different relevance ranking strategy. this capability becomes significant when considering the differences in the data being indexed for isbn/issn as compared to a general keyword search. since the keyword anywhere index contains the majority of the fields in a marc record and is the default search operator, its relevance ranking strategy received the most attention. this strategy currently consists of seven modules. the first five modules rank results in a dynamic fashion, while the final two modules provide static ordering based on publication date and total circulation. the ncsu libraries, algorithm prioritizes results with the query terms exactly as entered (no spell-correction, truncation, or thesaurus matching) as most relevant. for multiterm searches, results containing the exact phrase are considered more relevant than those that do not. in addition, ncsu has created a field priority ranking, which 130 information technology and libraries | september 2006 provides the capability to define matches that occur in the title as more relevant than matches that occur in the notes fields. the relevance algorithm also considers factors such as the number of times the query appears in each result and the term frequency/inverse document frequency (tf/idf) of query terms. the unprecedented nature of using this particular set of tools to define relevance algorithms in library catalogs meant that the initial configuration required a best guess approach. the ability to quickly change the settings and re-index provided the opportunity both to learn by doing and test assumptions. much work remains, however, including systematic testing of the “matchallpartial” retrieval technique. while not a true probabilistic or vectorbased matching approach, the “matchallpartial” retrieval technique will broaden a search by dropping individual query terms if no results are returned. however, this type of retrieval technique creates the challenge of developing an intuitive interface that helps users understand partial matching (although many users must be aware that this is how google works). spell correction, “did you mean . . . ,” and sort several other features are included in the basic endeca iap application. these include auto-correction of misspelled words, which uses an index-based approach based on frequency of terms in the local database rather than a dictionary. due to the presence of unique terminology in the database (particularly author names), the relevance ranking has been configured to display any matches on the user’s original term before spell-corrected matches. a “did you mean…” feature also checks queries against terms indexed within the local database to determine if another possible term has more hits than the original term in order to provide the user the option to resubmit the search with a different spelling. various sort options are supported, including date, title, author, and “most popular.” ฀ browse whatever the shortcomings of the card catalog, a library user could approach it with no query in mind; any drawer could be browsed. with the advent of online catalogs, this is no longer possible: an initial search is required to enter the system. marchionini characterizes “browsing strategies” as “informal and opportunistic.”15 a good catalog browse should simulate the experience of browsing the stacks, even potentially improving upon it since the virtual browser can jump around. many patrons cite the serendipity of browsing the stacks and “recognizing” relevant resources as a key part of their discovery process. with more books moving to online formats and off-site storage (and therefore, unable to be browsed), enhancing virtual browsing in the catalog becomes increasingly important. as borgman points out, “few systems allow searchers . . . to pursue non-linear links in the database.”16 key browsing features provided by the endeca software are faceted navigation and the ability to browse the entire collection without entering a search term. although most modern search engines support both fast response times and relevance ranking, the opportunity to apply endeca’s guided navigation feature to the highly structured marc record data was particularly intriguing. guided, or faceted, navigation exposes the relationships between records in the result set. for example, a broad topical search might return thousands of results. classification codes, subject headings, and item-level details can be used to define logical clusters for browsing—post-coordinate refinement—within the result set. since these refinements are based on the actual metadata of the records in the result set, users can never refine to less than one record, (i.e., there are no “dead ends”).these clusters, or facets, are known as dimensions. users are able to select and remove values from all available dimensions in any order to assist them as they browse through the result set. endeca’s dimensions, while able to be browsed, are not available only as post-coordinate search refinements, however. using the endeca application, library catalogs can once again give users the ability to browse the entire set of records without first entering a search term. any of the dimensions can be used to browse the collection in this fashion, and the ability to assign item-level information (e.g., format, availability, new book), as well as bibliographic-record elements, to the dimensions further enhances the browsing functionality. ฀ improving subject access given the unsuitability of library of congress subject headings (lcsh) as an entry vocabulary, improving topical (subject) access in catalogs centers around keyword searching. while keyword searches query the subject headings as they do the rest of the record, most systems do not take advantage of the fact that subject headings are controlled and structured access points or use the subject information embedded in the classification number. the endeca-powered catalog, in addition to addressing classic keyword-search problems by introducing relevance ranking, implied phrase, spell correction, and stemming, also leverages the “ignored” controlled vocabulary present in the bibliographic records—subject headings and classification numbers—to aid in improving topical searching. this is a system design concept that has been discussed in the literature on improving subject toward a twenty-first-century library catalog | antelman, lynema, and pace 131 access but has not until now been manifest in a major catalog implementation. as chan noted, “subject headings and classification systems have more or less operated in isolation from each other.”17 the endeca-powered catalog interface is an experiment in presenting users with these two different, but complementary, approaches to categorizing library materials by subject. classification several catalog experiments created retrieval clusters based on deweyand ddc-classification schemes and captions in order to improve subject access by expanding the entry vocabulary and as a way to improve precision and recall.18 using the lc classification is more challenging, however, as it is not hierarchical. still, the potential of its use has been noted by bates and coyle; and larson experimented with creating clusters (“classification clusters”) based on subject headings associated with a given lc class.19 in larson’s system, the interface suggested possible subject headings of interest, an approach similar to that of displaying the subject facets alongside the result set in the endeca catalog. there is some evidence from early usability studies that exposing the classification, much as it was physically exposed in the card catalog, is useful and desired by catalog users. markey summarizes findings of a 1981 council on library resources study in which many institutions conducted usability testing. positive aspects of card-catalog use that people wanted to see in the opac included, a “visual overview of what is available in the library,” and “serendipity.”20 but there is a difference between using the classification scheme to identify subject headings and displaying the classification itself in the user interface. the latter can be problematic from a usability perspective, as larson pointed out, because the classification scheme and terminology are not transparent.21 imagine the would-be browser of a library’s computer-science collection having to know to select first q science, then qa1–qa939 mathematics, and then qa71–qa90 instruments and machines before possibly recognizing that qa75–qa76.95 calculating machines included computer science? despite these potential problems, because the endeca software supported display of the lc classification as a dimension, ncsu decided to experiment with its utility by making it available on the results screen. entry vocabularies entry vocabularies or mappings apply to all types of retrieval models. they address the general problem of reconciling a user’s query vocabulary with the index vocabulary represented in the catalog or documents.22 studies show that users’ query vocabulary is large (people rarely pick the same term to describe the same concept) and inflexible (people are unable to repair searches with synonyms.)23 because of this, bates refers to the objective of the entry vocabulary as the “side-of-abarn principle.”24 several approaches have been taken to develop this functionality. building on larson’s “classification clustering” methodology, buckland created an entry vocabulary module by associating dictionaries created by analyzing database records.25 the result was natural language indexes to existing thesauri and classification systems. while the endeca-powered catalog does not yet incorporate an entry vocabulary, its exposure of the index vocabulary to the user in subject dimensions could be said to be a limited side-of-a-barn approach. the limitation is that only controlled vocabulary from the retrieved records is exposed as dimensions on the results screen; relevant records not retrieved because of a lack of match between query vocabulary and terms in the record will not have their facets displayed. were an entry vocabulary for lcsh available, endeca’s synonym-table feature could be used to map between query terms and lcsh. ฀ implementation the library’s information technology advisory committee appointed a seven-member representative team to oversee the implementation. preparatory steps included sending key development staff to training and a two-day meeting with endeca project managers to establish functional and technical requirements. architecture knowing that the endeca application would not completely replace ncsu’s integrated library system, determining how best to integrate the two products was part of the implementation process. the endeca iap coexists with the sirsidynix unicorn ils and the sirsidynix (web2) online catalog, indexing marc records that are exported from unicorn’s underlying oracle database. figure 1 depicts the integration of the endeca software with existing systems. although the endeca software is capable of communicating directly with the database that supports the unicorn ils, ncsu chose the easier path of exporting marc records into text files for ingest by endeca. the marc4j api is used to reformat the exported marc records (which include itemlevel information in 999 fields) into flat text files with utf-8 encoding that are parsed by endeca’s data foundry process. nightly shell scripts export updated and new records from ils, merge those with the base endeca files, and start the re-indexing process. the indexing of seventy-three marc 132 information technology and libraries | september 2006 record fields and ten dimensions results in an index size of approximately 2.5 gb. the entire index resides in system memory. the endeca data foundry can easily parse and reindex the approximately 1.7 million titles in ncsu’s holdings nightly (in stark contrast to the more than 3 days of downtime required to re-index keywords in unicorn). the relative speed of this process and the fact that it does not interfere with the front-end application prompted the decision not to implement “partial indexing” at the outset. though there was little doubt among staff as to the increased capabilities of keyword searching through endeca, the implementation team decided that authority searching (author, title, subject, call number) would be preserved in the new catalog interface. this allowed ncsu to retain the value of authority headings, in addition to providing a familiar interface and approach to known-item searching. since the detailed record in web2 included the capability to save records, place requests, and send systemsuggested searches (“more like this”), the implementation team also decided to link from titles in the endeca-powered results page to the web2 detailed record. only slight modifications were required to stylize this display in a manner consistent with the new interface. the front-end interface for keyword searching in endeca is a java-based web application built in-house. this application is responsible for sending queries to the endeca mdex engine—the back-end http service that processes user queries—and displaying the results that are returned. user-interface design because it is created by the customer, ncsu libraries has complete control over the look, feel, and layout of the endeca search-results page. indexes, properties, and dimensions the implementation team began the process of making indexing decisions by looking at the fields indexed in the unicorn keyword-index file. this list included 161 marc fields and subfields, including more than thirty fields that are never displayed to the public. this kitchen-sink approach was replaced with a more carefully selected list less than half that number. the implementation team defined eleven dimensions for use with endeca’s faceted navigation feature. once users enter a search query, they can explore the result set by selecting values from these dimensions: availability; lc classification; subject: topic; subject: genre; format; library; subject: region; subject: era; language; and author (see figure 2). the eleventh dimension is not displayed on the results page, but is used to enable patrons to browse new titles. each dimension value also lists the number of results associated with it; most dimensions are listed in frequency order. search interface once the implementation team made some preliminary decisions regarding dimensions and search indexes, wireframes were created to assist in the iterative design process for the front-end application. while the positioning of the dimensions on the results page and the display of holdings information was well debated, the design of the catalog search page was an even hotter topic. integration of both endeca keyword searching and web2 authority searching required an interface that could help users differentiate between the two tools. a survey of the keyword-versus-authority searching distinction in a variety of library catalogs led to the development of four mock-ups. the implementation team chose a search tab that includes separate search boxes for keyword and authority searching, as well as search figure 1. ncsu endeca architecture figure 2. dimensions toward a twenty-first-century library catalog | antelman, lynema, and pace 133 examples dynamically displayed based on the index selected. authority searching was relabeled “begins with” searching to let users know that this particular search box featured known-item searching (although it is also where lcsh searching is found) (see figure 3). an advanced search tab re-creates the pre-coordinated search options from the web2 search interface using endeca search functionality. one unique new feature allows users to include or exclude reference materials and government documents from their results. a true boolean search box is made available here, primarily for staff. browse while users can submit a blank search and browse the entire collection by any of the dimensions, the browse tab specifically supports browsing by lc classification scheme (see figure 4). this tab also includes a “new titles” browse that can easily be refined with faceted navigation. at the time of this writing, there are plans to pull out other dimensions, such as format, language, or library, for browsing. this will be a great stride forward since there has traditionally been no way to perform a marc codes-only search (in order to browse all chinese fiction in the main library, for example). assessment the endeca-powered catalog seems self-evidently a better tool to help users find relevant resources quickly and intuitively. but since so much of the implementation involved uncharted territory, plans for assessment began before the launch of the interface, and the actual assessment activities began shortly thereafter. the library identified five assessment measures prior to implementation. one of these, however, requires longer time-series data (changes in circulation patterns), and another, the application of new and potentially complex log-analysis techniques (path analysis). other measures relate to use of the refinements, “sideways searching,” and objective and subjective measurements of quality search results, some of which can be preliminarily reported on here. log analysis to learn more about how patrons are using the catalog, data from two months of search logs were analyzed. while authority searching using the library’s old web2 catalog is still available in the new interface, search logs show that authority searching has decreased 45 percent and keyword searches have increased 230 percent. it is noted, however, that a significant—and indefinable—component of this increase in keyword searching is due to the fact that the default catalog search was changed from title to keyword. users are taking advantage of the new navigational features. fifty-five percent of the endeca-based search requests are simple keyword searches, 30 percent represent searches where users are selecting post-search refinements from the dimensions on the results page, and the remaining 15 percent are true browses with no search term entered (this figure includes use of browse new titles). dimensions the horizontal space just above the results is used to display the full range of results within the lc classification scheme (see figure 2). the first dimensions in the left column focus on the subject dimensions (topic and genre) that should be pertinent to the broadest range of searches. the following format and library dimensions recognize that patrons are often limited by time and space. when designing the user interface, it was not known which dimensions would be most valuable. as it turned out, dimension use does not exactly parallel dimension placement. lc classification is the most heavily used, followed closely by subject: topic, and then library, format, author, and subject: genre. since no basis for the placement of dimenfigure 3. new catalog search interface figure 4. browse by lc classification and new titles 134 information technology and libraries | september 2006 sions existed at the time of implementation, the endeca product team plans to use these data, after some time, to determine if changes in dimension order are warranted. spell correction and “did you mean . . .” approximately 6 percent of endeca keyword searches responded to the user’s query with some type of spelling correction or suggestion: 3.6 percent performed an automatic spell correction, and 2.8 percent offered a “did you mean…” suggestion. while ncsu has not analyzed how many of the spell corrections are accurate or how many of the “did you mean…” suggestions are being selected by users, future work in this area is planned. recommender features two features in endeca that have seen a surprising amount of use are the “most popular” sort option and the “more titles like this” feature available on the detailed-record page for a specific title. both relate broadly to the area of recommending related materials to patrons. the “most popular” sort option is currently powered by aggregated circulation data for all items associated with a title. while this technique is ineffective for serials, reference materials, and other noncirculating items, it provides users a previously unavailable opportunity to define relevance. to date, the “most popular” sort is the second most frequently selected sort option (after publication date, at 41 percent), garnering 19 percent of all sorting activity. most-popular sorting was trailed by title, author, and call-number sorting. when viewing a detailed record, users are given the option to find “more titles like this” or “more by these authors.” the first option initiates a new subject keyword search combining the phrases from the $a subdivision of all the subject (6xx) fields assigned to the record. the latter option initiates an author keyword search for any of the authors assigned to the current record. while there are not good statistics on use of this feature, these subject strings appear regularly in the list of most popular queries in search logs. assessing top results if relevance ranking was effective, one would expect to see good results on the first page. but what are “good” or “relevant” results? greisdorf finds that topicality is the first condition of relevance, and xu and chen’s more recent study finds topicality and novelty to be equally important components of relevance.26 while someone other than the searcher might be able to assess topical relevance, it is impossible to assess novelty, since it cannot be known what the searcher already knows. although researchers agree that relevance is subjective—that is, only a searcher can determine whether results are relevant—janes showed that trained external searchers do a reasonably good job of approximating the topical relevancy judgments of users.27 the analysis reported here focuses on topicality (using a liberal interpretation of what might be topically relevant). ncsu libraries sought to measure how many of the top search results are likely to be relevant to the user ’s query in the old and new catalogs. methodology one of the authors searched 100 topical queries (taken from 2005 search logs) in both web2 and endeca catalogs using “keyword anywhere.” topical queries whose meaning was unclear (e.g., “hand wrought”) were excluded. the topical relevance of the top hits (up to five) was coded for each target. because not all search-result sets contained five records, success for each was measured as a ratio (e.g., 2/5 = .4). those searches that resulted in 0 records in both targets were discarded, while those that resulted in 0 records in target a but “found relevant results” in target b were counted as 0 in target a. the ratios were then averaged for each target and compared to determine the difference in relevance-ranking performance. finally, a random subset of forty-four of the queries was selected, and the placement in the web2 results of the first result in endeca was noted. results on average, 40 percent of the top results in web2 were judged to be relevant, while 68 percent of the top results in endeca were judged to be relevant. that represents a 70 percent better performance for the endeca catalog. if one makes the assumption that the first endeca record is relevant (admittedly an assumption), based on these data, then one can look at the average position of that record in the old catalog. it was found that the first hit in endeca fell between #1 and #4126 in web2, with more than a third falling after the second screen of results, the maximum number of screens users are typically willing to examine.28 while this level of increased performance is impressive, it masks some dramatic differences in the respective result sets. looking at a broad search, “marsupial,” all of the top five hits in endeca have “marsupial” in the title and “marsupials” or “marsupialia” as a subject heading. the result set includes seventy-eight records, thanks to this intelligent stemming. in the web2 result set, just twenty-nine records, not a single one of the top five has “marsupial” in the title or subject headings (and the top two results, tributes to malcolm c mckenna and poisonous plants and related toxins, are highly unlikely to be relevant). it is not until record #10 that you see the first item that contains “marsupial” in the title or subject. this single example demonstrates the benefit of both relevance ranking and stemming. toward a twenty-first-century library catalog | antelman, lynema, and pace 135 usability testing as a result of a long history of catalog-usability studies, there are things that are known about library catalog users. one is that people both expect systems to be easy to use and find that they are not.29 usability testing was conducted to compare student success in using the new catalog interface with that of students using the old catalog interface when completing the same set of ten tasks. ten undergraduate students were recruited for the test. five were randomly selected to use the old web2 catalog, while the other five used the new catalog interface, which allows users to choose between a keyword search box powered by endeca and an authority search box (begins with . . . ) that is still powered by web2. the test contained four known-item tasks and six topical-searching tasks (appendix a). task success, duration, and difficulty were recorded. user satisfaction was not measured since catalog usability studies have found that satisfaction does not correlate with success.30 task duration figure 5 shows the average task duration for the topical tasks (5–10) for web2 and endeca. except for task 9*, there is clearly a trend of significantly decreased average task duration for endeca catalog users. the endeca catalog shows a 48 percent improvement in the average time required to complete a task (01:34 in web2 compared to 00:49 in endeca). it is also noted that, although results from known-item searching tasks (1–4) are not reported in detail here, test subjects were just as successful in completing them using keyword searching in the endeca catalog as they were using authority searching in web2. task success and difficulty in addition to task duration, the test moderator assigned a difficulty rating to each task attempted by the participants: easy, medium, hard, or failed. figure 6 illustrates the overall task-attempt difficulty for topical tasks (5–10) in the web2 and endeca catalogs. the largest improvement is in the increased percentage of tasks that are completed easily in endeca and the nearly equivalent decrease in the percentage of tasks that were rated as hard to complete. while a significant number of tasks were still failed using the endeca catalog, many of these failures can be attributed to participants’ propensity to select keyword in subject rather than keyword anywhere searches. in fact, the only instances where keyword anywhere search in the new catalog failed to lead to successful task completion were for a single participant who was unwilling to examine retrieved results closely enough to determine if they were actually relevant to the task question, assuming too quickly that the task had been completed successfully. terminology participants using both the web2 and endeca catalog interfaces expressed confusion over some of the terminology employed. one of the most problematic terms was “subject.” a number of participants selected keyword in subject for topical searches because of the attraction of the word “subject.” none of the participants recognized that this term referred to controlled vocabulary assigned to records. coupled with a slight unfamiliarity with the term “keyword,” not typically used in web searching, this misunderstanding led participants to misuse (or overuse) keyword in subject searches when they could have found results more effectively using general keyword searching. this terminology problem appears to be an artifact of the usability testing, however. looking at the search logs, more than 50 percent of the keyword searches were keyword anywhere searches, while only 4 percent represented keyword in subject searches. relevance relevance ranking of search results is clearly the most important im-provement in the new catalog. students in this usability test all looked immediately at the first few results on the first page to determine if their search had produced good results. if they didn’t like what they saw, they were likely to retry the search with fewer or more keywords in order to improve their first few results. one participant figure 5. average task duration: web2 versus endeca * while task 9 may appear to be an aberration, it actually reveals effective use of new functionality. this task required users to locate an audio recording of poetry in spanish. in web2, three of five participants completed the task successfully, all using the material type and language limits available in the advanced search tab. the two participants who didn’t locate this tool failed to complete the task. in endeca, two participants used the same advanced search limits to complete the task successfully and two additional participants were able to locate and use endeca dimensions to complete the task successfully. this suggests that the new interface is providing users with more options to help them arrive at the results they seek. 136 information technology and libraries | september 2006 using the web2 catalog expressed the need for relevance ranking, “once i scroll through a page, i get pretty discouraged about the results.” the number of paging requests recorded in system logs confirms that users are focusing on the first result screen (with ten results per page); only 13 percent of searchers go to the second page. use of dimensions when questioned after the test, all five participants who used the endeca catalog intuitively understood that dimensions could be used to narrow results. however, only three used the dimensions during the test. throughout the tests, the student participants frequently attempted to limit their search at the outset, rather than beginning with a broad search and then refining. it is unclear whether this behavior is a function of the very specific nature of the test questions or experience with the old catalog. log data show that users are indeed entering broad keyword searches with only one or two terms, which implies that dimensions may be more useful than this usability test indicates. it is also interesting to note that while none of the students understood that the lc classification dimension represented call-number ranges, they did understand that the values could be used to learn about a topic from different aspects—science, medicine, education. ฀ future directions weeks before the initial application went live in january 2006, the list of desired features had grown long. some of these were small “to do” items that the team did not have time to implement. others required deeper investigation, discussion, and testing before the feature could be put into production. still others may or may not be possible. a few of ncsu’s significant planned development directions are summarized below. functional requirements for bibliographic records there is much interest in the utility of applying the functional requirements for bibliographic records model to online catalogs.31 endeca includes a feature called “record rollup” that allows retailers to group items together for example, different sizes and colors of a shirt. all that is required for this feature is a rollup key. ncsu, working with oclc, has elected to try the oclc work identifier to take advantage of this functionality and create work-level record displays in the endeca catalog hit list. subject access the collective investment libraries have made in subject and name authorities is leveraged with the faceted navigation features of endeca. but only authorized headings in records are seen by endeca, cross-references in the subjectauthority record are not used. during implementation, the team looked at ways to improve the entry vocabulary to authorized-subject terms by loading the 1xx and 4xx fields from the subject-authority file into endeca synonym tables so that users could be guided to proper subject terms. the team still views this as a promising direction, but simply did not have time to fully explore it prior to implementation. additional discussions with oclc centered on their faceted access to subject terms (fast) project. fast terms are more amenable than lcsh headings to being broken up into topical, geographic, and time-period facets without losing context and meaning. the normalization of geographic and time-period subdivisions promises to be particularly useful. fast has, to date, lacked a ready interface for the application of its data. while the fast structure is more conducive to non-cataloger metadata creation and post-coordinate refinement, it still does not meet the need figure 6. topical task success and difficulty: web2 versus endeca toward a twenty-first-century library catalog | antelman, lynema, and pace 137 for a user-entry vocabulary.32 were such a vocabulary for lcsh to become available, it could be mapped to synonym tables to lead users to authorized headings. abandon authority searching? the future of authority searching, however, is less clear. although the usability testing described in this paper showed that the endeca keyword search tools performed on a par with the old catalog for known-item searching, it is recognized that authority searching serves more functions. clearly, collocation of all books on a topic is absent when a user does a topical search using keyword rather than a controlled subject heading. but there are more subtle losses as well. as chan points out, one purpose of subject access is to help users focus searches, develop alternative strategies, and enable recall and precision.33 this is not possible with a simple keyword search, unless the searcher discovers that he can search on a subject heading from a record of interest. the display of subject facets in the endeca-powered catalog works to counter this weakness of simple keyword searching. another navigation aid in the traditional authority display that is lost in a simple keyword-search result is visible “seams.” as mann points out, “seams serve as perceptible boundaries that provide points of reference; without such boundaries, readers get ‘lost at sea’ and don’t know where they are in relation to anything else: they can’t perceive either the extent of what they have, or what they don’t have.”34 until users have confidence that a known item will appear at the top of a results list if the library holds that item, with a large keyword result set, one cannot confirm a “negative result” without browsing through the entire set. the endecapowered catalog interface does not help to address either the “seams” or the negative-result problem, which are two reasons why ncsu maintained authority searching. an integration platform despite the vast improvements found in the endeca catalog, the fact remains that it is still mainly books—as calhoun says, “only a small portion of the expanding universe of scholarly information.”35 there are two approaches to take with the endeca platform: one is to take advantage of having control over the data and the interface to facilitate incorporation of outside data sources to enhance bibliographic records. the second is to put other, non-catalog data sources under the endeca search-and-navigation umbrella. the middleware nature of the endeca platform makes either approach more promising than the “square peg and round hole” problem of trying to work with library management systems illequipped to handle a diversity of digital assets. whether as a feed of catalog data to a metasearch application or web-site search tool, or as a platform for faceted access to electronic theses, institutional repositories, or electronic books, endeca has clear potential as a future platform for library resource discovery. ฀ conclusion while it cannot be claimed that this endeca-powered catalog is a third-generation online catalog, it does implement a majority of the third-generation catalog features identified by hildreth. most notably, through navigation of subject and item-level facets, the endeca catalog supports two of his objectives, “related record search and browse” and “integration of keyword, controlled vocabulary, and classification-based approaches.” spell correction, intelligent stemming, and synonym tables support “automatic term conversion/matching aids.” the flexible relevance-ranking tools support “closest, best-match retrieval” as well as “ranked output.” much work remains, however. three important features identified by hildreth cannot be said to be implemented in this catalog at this time: “natural language query expression,” that is, an entry vocabulary, “expanded coverage and scope,” and “relevance feedback methods.”36 requirements for these features are either being reviewed or are already under development by both endeca and ncsu libraries. ncsu views the endeca catalog implementation in the context of a broader, critical evaluation and overhaul of library discovery tools. like the library web site, the catalog still requires users to come to it. when they do, it still sets a high threshold for patience and the ability to interpret clues. still, at the end of the day it rewards the ncsu student searching “declaration of independence” with the book, american scripture: making the declaration of independence instead of the recent congressional resolution, recognizing the mexican holiday of cinco de mayo. references 1. christine l. borgman, “why are online

appendix a: ncsu libraries catalog usability test tasks tending to an overgrown garden: weeding and rebuilding a libguides v2 system article tending to an overgrown garden weeding and rebuilding a libguides v2 system rebecca hyams information technology and libraries | december 2020 https://doi.org/10.6017/ital.v39i4.12163 rebecca hyams (rhyams@bmcc.cuny.edu) is web and systems librarian, borough of manhattan community college/cuny. © 2020. abstract in 2019, the borough of manhattan community college’s library undertook a massive cleanup and reconfiguration of the content and guides contained in their libguides v2 system, which had been allowed to grow out of control over several years as no one was in charge of its maintenance. this article follows the process from identifying issues, getting departmental buy-in, and doing all of the necessary cleanup work for links and guides. the aim of the project was to make their guides easier for students to use and understand and for librarians to maintain. at the same time, work was done to improve the look and feel of their guides and implement the built-in a-z database list, both of which are also discussed. introduction in early 2019, the a. philip randolph library at the borough of manhattan community college (bmcc) (part of the city university of new york (cuny) system) hired a new web and systems librarian. the position itself was new to the library, though some of its functions had previously been performed by a staff member who had left more than a year prior. it quickly became apparent to the newest member of the library’s faculty that, while someone had at one point managed the website, the same could not really be said for the library’s libguides system and the mass of content contained within. the library’s libguides system was first implemented in january 2013 and over time the system came to be used primarily by instruction librarians to serve their teaching efforts. not long after bmcc implemented libguides, springshare announced libguides version 2 (v2), a new version of the system that included several enhancements and features not present in the earlier version.1 these features included the ability to mix content types in a single box (in the earlier version, for example, boxes could have either rich text or links but not both), a centrally managed asset library, and an automatically-generated a-z database list designed to make it easy to manage a publicfacing display. bmcc moved to libguides v2 around early 2015, but few of those who worked with the system ever took advantage of the newer features offered for quite some time, if at all. at the time the web and systems librarian came aboard, the bmcc libguides system contained over 400 public guides and an unwieldy asset library filled with duplicates and broken widgets and links. many of the guides essentially duplicated others, with only the name of the classroom instructor differing. there were, for example, 69 separate guides just for english 101, some of which had not been updated in three or four years. there were there no local guidelines for creating or maintaining guides, and in theory, each librarian was responsible for their own. however, it was apparent that in practice, no one was actively managing the guides or their related assets, as the lists of both were overwhelming. the creators of existing guides were primarily reference and instruction librarians whose other responsibilities meant there was little mailto:rhyams@bmcc.cuny.edu information technology and libraries december 2020 tending to an overgrown garden | hyams 2 time to do guide upkeep and because there was no single person in charge of the guides, there was no one to ensure any maintenance took place. in addition to the unwieldy guide list and asset library, the bmcc library was also effectively maintaining two separate a-z database lists, one on the library’s website that was a homegrown sql database built by a previous staff member, and another running on libguides to provide links to databases via the guides. the lists were not in sync with one another and several of the librarians were unaware that the libguides version of the list even existed, leading to links to databases appearing on both the database list and as link assets. and, while the libguides a -z list was not linked from the library’s website, it was still accessible from points within libguides, meaning that patrons could encounter an incorrect list that was not being maintained. getting started before any work could be done on our system, there needed to be buy-in from the rest of the library faculty. with the library director in agreement, agenda items were added to department meetings between march and may 2019 for discussion and department approval. the various aspects of the project were pitched to emphasize the following goals: • removing outdated material, broken links, etc. • streamlining where information could be found • decluttering guides to make everything easier to use and understand for students • improving the infrastructure to make maintenance and new guide creation easier and more manageable • standardizing layouts and content the aim of all of this would be to increase guide usability, accessibility, and make the guides overall a more consistent resource for our students. for the sake of transparency (as well as to have a demo of some of the aesthetic changes discussed in more detail below), a project guide was created and shared with the rest of the library department to share preliminary data as well as detailed updates as tasks were completed.2 process the database list while the libguides a-z database list, a feature built into v2 of the platform, contained information about our databases, it was essentially only serving to provide links to databases when creating guide content. there was some indication, in the form of a dormant a-z database “guide,” that someone had tried to create a list in libguides by manually adding assets to a guide. while that was a common practice in libguides v1 sites, as the built-in list was not yet a part of the system, the built-in list itself was never properly put into use. the links on our website all pointed to a homegrown list which, while powered by an sql database, was essentially a manual list. because of its design, it had proved impossible for anyone in the library to update without extensive web programming knowledge. it seemed a no-brainer to work on the database list first. this way we had both the infrastructure to update database-related content on the guides and a single and up-to-date list of resources with enhanced functionality that could benefit the library’s users almost immediately.3 information technology and libraries december 2020 tending to an overgrown garden | hyams 3 to begin, the two lists were compared to find any discrepancies, of which there were many. as the e-resources librarian was on leave at the time, the library director was consulted to determine which of databases missing from the libguides list were active subscriptions (and which of the ones missing from the homegrown list were previously cancelled so they could be removed). once the database list reflected current holdings, the metadata entries for the databases on the libguides side were updated to include resource type, related subjects, and related icons. these updates would enhance the functionality of the libguides list, as it could be filtered or searched using that additional information, something that was missing from the homegrown lis t. in addition to updating content and adding useful metadata, some slight visual changes were made to improve the look and usability of the list using custom css. most of this was done because as the list was being worked on, several librarians (of those who were even aware of it in the first place) mentioned that one reason they disliked the libguides list was because of the font size and spacing, which they felt was too small and hard to read. with the list updated, it was presented at the march 2019 department meeting and quickly won over all in attendance, especially when it was pointed out that the list could be very easily maintained because it required no special coding knowledge. while the homegrown list would remain live on the server for the rest of the semester (so as to not disrupt any classes that may have been using it), it was agreed that the web and systems librarian could go ahead with switching all of the links pointing to the homegrown list to point to the springshare list instead. the asset library because of how guides were typically created over the years since adopting libguides (many appeared to have been copied from another existing guide each time) the asset library had grown immense and unmanageable. for example, there were 149 separate links to our “databases by subject” page on the library’s website, the overwhelming majority of which were only used once. there were also 145 separate widgets for the same embedded scribd-hosted keyword worksheet, which was in fact broken and displayed no content. this is to say nothing of the broken-link report that no one had reviewed in quite some time. tackling the cleanup of duplicates and fixing of broken links/embeds was a large piece of the invisible work taken on behind the scenes to make maintaining the guides easier in the future. in order to analyze the data, the asset library report was exported to an excel file to make it easier to identify issues that needed correction. to start this process, we requested that springshare technical support wipe out all assets (other than documents) that were not mapped to anything and were just cluttering up the asset library (this ended up being just under 2,000 assets).4 most of those items had been removed from the guides they were originally included on but were never removed from the asset library. they served no real function other than to clutter up the backend. the guide authors had given the web and systems librarian permission to remove anything broken that could not be easily fixed. this included the aforementioned broken worksheet (and other similar items), as well as an assortment of youtube video embeds where the video had since been taken down, resulting in a “this video is unavailable” error message. it was felt that since those were already not working and seriously hurt the reliability of our guides to our users, that no further permission was needed. then came the much more tedious task of standardizing (where possible) which assets were in use. this involved going into guides listed as containing known-duplicate assets, replacing them with a single, designated asset, and then removing the resulting unmapped items.5 it was decided information technology and libraries december 2020 tending to an overgrown garden | hyams 4 that while many of the guides would likely be deleted after the spring semester, that only assets appearing on currently-active guides would be standardized. while in hindsight, as many of the links that were fixed were on guides that were soon-to-be deleted, it would have been better to hold off and wait until guides could be deleted first. however, doing at least some of this work in advance helped find other issues including instances where our proxy prefix was included directly in the url (an issue as we were also in the process of changing our ezproxy hosting) and where custom descriptions or link names were unclear. “books from the catalog” assets had their own issues that also needed to be addressed. with a pending migration of the library’s ils, it was already apparent that the links to any books in the library’s catalog would need updating so they could have a shot at continuing to function postmigration.6 we had been told at the time that the library’s primo instance would remain through the migration (though this changed during the migration process) so at the time we felt it important to ensure that all links were pointing to primo, as some had been pointing to the soonto-be decommissioned opac. for consistency, the urls were structured as isbn searches instead of ones relying on internal system numbers that would soon change. however, it became obvious very early on that some of the links to books were either pointing to materials that were no longer in the library’s collection, or were pointing to a previously decommissioned opac server, both of which resulted in errors. because the domain of the previously decommissioned opac server had been whitelisted in the link checker report settings, these items had not appeared on the broken link list. using the filtered list of “books from the catalog” assets, all titles were checked, which allowed the web and systems librarian to remove items that were no longer in the collection and make other adjustments as needed. as a result of the asset cleanup process, the asset library went from an unwieldy total of more than 5,000 items to just over 2,000 items. it also simplified the process for reusing assets in new guides, as there was now only one choice per item, and made it much easier to find and fix broken links and embeds. the guides the cleanup of the guides themselves was by far the most complex task. before starting the guide cleanup work itself, the web and systems librarian performed a content analysis to identify and recommend guides for deletion and which could be converted into general subject area guides. because a common practice was to create a “custom” guide for each class that came in for a library instruction session, there was an overrepresentation of guides for the classes that had regular sessions: english 101 (english composition), english 201 (introduction to literature), speech 100 (public speaking), and introduction to critical thinking. those four courses accounted for 187 guides, or over 40 percent of the total number in our system. the majority of them had not been updated directly in over three years, and in some cases, were designed for instructors who no longer taught at the college. perhaps more telling was that the content for these guides diff ered more across the librarians who created them than across the courses they were designed for. this meant that while there might be three or four different iterations of the english 101 guide, the guides created by the same librarian for different introductory courses were essentially the same. before the arrival of the web and systems librarian, one of the other librarians had been occasionally maintaining guide groups for “current courses” and “past courses,” but it was unclear if anyone was still actively maintaining these groupings, as guides for current instructors were sometimes under “past courses” and vice versa. because these groups did not actually hide the information technology and libraries december 2020 tending to an overgrown garden | hyams 5 guides from view on the master list of guides and appeared to be unnecessary work, it was decided to remove the groupings. instead, the web and systems librarian would plan to revisit the guides on a regular basis to unpublish/remove anything for courses that were no longer taught. however, since the philosophy behind the guides was to move from “custom” guides for each instructor’s section to a general guide for the course as a whole for the overwhelming majority of cases, the need for maintaining these groupings was essentially eliminated anyway. in may 2020, a preliminary list of guides to be deleted was presented to the librarians at the monthly department meeting. the list was broken down as: • duplicates to be deleted: this portion consisted primarily of course guides like those mentioned above where multiple guides existed for the same course, most of which used the exact same content. • guides to be “merged:” while merging guides is not actually possible in the libguides platform, there were cases where we had two or three for the same course. they could be condensed into a single guide with the rest deleted. • guides to convert to subject area guides: these were guides that were essentially already structured as a subject guide but were titled for a specific course, and in many cases, a guide for the subject area did not already exist (for example, a course-specific guide for business would become the business subject area guide). • dead guides: these were guides that had not been updated in more than two years and had not been viewed in at least one year. librarians were given an opportunity in the department meeting to comment on the list, as well as to contact the web and systems librarian with any comments. additionally, as some of the classroom faculty on campus had connections to specific guides, the library director also sent out a message to classroom faculty to let them know of our general plan to revamp the guides and that many would be removed over the summer. surprisingly, there were few objections either amongst the librarians or the classroom faculty once they understood the rationale and process. of the few classroom faculty members that did respond to the library director’s message, most of them were more concerned with content or specific links that they felt strongly about versus the guides themselves. in those cases, we noted the content requests to make sure they appeared on the new guides. most of these instructors were satisfied when we further explained our process and , if needed, ensured them that the content they requested would be worked into the new guide. only one instructor who responded, whose assignment was related to a grant they had received, made a strong case for keeping a separate guide for their sections of english 101. with the project approval out of the way, it was then time to begin removing all of the to-bedeleted guides and start the process of revamping those that would be kept. the goal was that the project would be completed by the start of the fall semester so that faculty and students would come back to a new (and hopefully, much improved) set of guides. removing debris to be cautious, a few preliminary steps were taken before the guides selected for deletion were removed. for starters, the selected guides had their status changed to “unpublished,” meaning that they no longer appeared on the public-facing list of guides. this gave everyone a chance to say something if a guide they were actively using suddenly went “missing.” these unpublished guides were then downloaded using the libguides html backup feature and saved to the department’s information technology and libraries december 2020 tending to an overgrown garden | hyams 6 network share drive. while the html backup output is not a full representation of the guide (the file generated displays as a single page and is missing any formatting or images that were included in the guide), it does include all of a guide’s content, meaning that a link or block of text can be retrieved from the backup in case of moments of “i know i had this on my guide before but....” because of the somewhat haphazard nature of our guides, deleting unwanted ones turned out to result in interesting and unexpected challenges. over the years, some of librarians had, from time to time, reused individual boxes between guides, but there was no consistency to the practice. while there was a repository guide for reusable content, not everyone used it or used it consistently. thankfully, libguides runs a pre-delete check, which proved to be invaluable in this process, as it showed if any of the boxes displayed on one guide were reused on any others. in most cases where boxes were reused, they were reused on guides that were also on the “to be deleted” list, but that was not always the case. by having that check we could find the other guides listed and make copies of the boxes that would have otherwise been deleted. if a box was reused on multiple guides that were being kept, it was copied to the reusable content guide and then remapped from there. cosmetic improvements in conjunction with the work being done to improve content of our guides, the web and systems librarian felt it was the perfect opportunity to update the guide templates and overall aesthetics to make the guides more visually appealing, especially considering little had been done in this area system-wide apart from setting the default color scheme. using the project guide as an initial sandbox, several changes were put into motion that would eventually be worked into new templates and pushed out to all of the reworked guides. the first, and perhaps biggest, change was the move from tab navigation to side navigation (an option first made available with the release of libguides v2). while there have been several usability studies that have debated using one over the other, in this case side navigation was chosen both for the streamlined nature of the layout as a whole (by default there is only one full content column), and because enabling the box-level navigation could serve as a quick index for anyone looking to find specific content on a page.7 side navigation also avoided the issue of long lists of tabs spilling into a second row, which further complicated page navigation. several changes to the look and feel of the guides were also put into place, with many of the changes coming from suggestions given on various libguide style or best practice guides or more general recommendations from web usability guidelines.8 perhaps most importantly, all of the font sizes were increased for improved readability, especially on box titles and headers, to better facilitate visual scanning. the default fonts were also replaced with two commonly used fonts from the google fonts library, roboto (for headings and titles) and open sans (for body text). additionally, the navigation color scheme was changed because the orange of the college’s blueand-orange color scheme regularly failed accessibility contrast checks and was described by some colleagues as “harsh on the eyes.” instead, two analogous lighter shades of blue (one of which was taken from the college’s branding documentation) were selected for the navigation and box titles respectively, both of which allowed for the text in those areas to be changed from white to black (again, for improved readability). figure 1 shows a typical “before” guide navigation design, and figure 2 shows a typical “after” design. information technology and libraries december 2020 tending to an overgrown garden | hyams 7 figure 1. a sample of guide navigation and content frequently found on guides before start of cleanup figure 2. navigation and content after revisions additionally, the web and systems librarian took this opportunity to go through the remaining guides to ensure they were all consistent. most of this work fell in the area of text styling, or rather, undoing text styling. it was clear from several of the guides that over the years, librarians had not been happy with the default font sizes or styles, which lead to a lot of customizing using the built-in wysiwyg text editor. not only did this create a nightmare in the code itself (as the wysiwyg editor adds a lot of extraneous <span> tags and style markup), but it also meant that the changes coming from the new stylesheet were not being applied universally as any properties assigned on a page overrode the global css. there was also the issue of paragraph text (<p>) that was sometimes styled as fake headings (made larger or bolder to look like headings, but not using the proper <h#> tags) which needed to be corrected for consistency and accessibility purposes. replanting and sprucing up with an overwhelming majority of the guides (and their associated assets) deleted, it was finally time to rework the remaining guides into clear, easy-to-use resources that would benefit our students. at this point the guides fell into three categories: • guides that just needed to be pruned and updated. • guides that should be combined into a single subject area guide. • guides that should be created to fill an unmet need. information technology and libraries december 2020 tending to an overgrown garden | hyams 8 pruning and updating tasks were generally the least-arduous, as many of the guides included content that was also housed on discrete guides (citations, resource evaluation, etc.). instead of duplicating, for example, citation formats on every guide, those pages were replaced with navigation-level links out to the existing citation guide. this was also the point that we could do more extensive quality control such as switching to a single content column which further emphasized the extraneous information on many of our guides. infographics, videos, and long blocks of links or text were scrutinized to determine if they were helping to enhance students’ understanding of the core content or if they were merely providing clutter that would make it more difficult to understand the important information.9 in some cases, by going from guide to guide, it became apparent that there were guides for multiple courses in a subject area where the resources were basically identical. this was most noticeable in the criminal justice and health education subject areas. in these cases, it made little sense to keep separate course guides when the content was basically the same across them. to remedy this duplication, one of the course guides for each subject was transformed into the subject area guide, and resources were added to ensure they covered the same materials that the separate course guides may have covered. the remaining course guides were then marked for future deletion as they were no longer needed. lastly, subject areas without guides were identified so that work could be done later to create them. as we had discussed moving towards using the “automagic” integration of guide content into our blackboard learning management system (lms), this step will be key in ensuring that all subject areas have at least some resources students can use. however, as of this time we have yet to finish creating these additional guides, and several subject areas (including computer science, nursing, and gender studies) have no guides at all. next steps now that all of the work to clean and update our libguides is done, the most important next step is coming up with a workflow to ensure that the guides stay relevant and useful. the web and systems librarian mostly left the guides alone for the fall 2019 semester to allow their colleagues time to use them and report back any issues. to the web and systems librarian’s surprise there were few issues reported, but that does not mean there is no room for future improvement. as a department, it is clear that we need a formal plan for maintaining the guides, including update frequency, content review, and guidelines for when guides should be added or deleted. additionally, immediately following the conclusion of this cleanup project the library’s website was forced into a server migration and full rebuild for reasons outside of the scope of this article. however, as a result there were changes made on the library’s site involving the look and feel of pages that will need to be carried through into our guides and associated springshare platforms. while most of this work is relatively simple, mimicking changes developed in wordpress to work properly on external services will take time and effort. conclusion overall, while this project was a massive undertaking (done almost entirely by a single person), the end result, at least on the surface, has made our guides much easier to use and understand. there were obviously several things that, if the project were to be done over, should have been done differently, mostly involving the cleaning of the asset library. however, it is now much easier information technology and libraries december 2020 tending to an overgrown garden | hyams 9 to refer students to guides for their courses and the feelings about the guides amongst the library faculty have become much more positive. endnotes 1 “libguides: the next generation!,” springshare blog (blog), june 26, 2013,

bulk deletion, documents were manually reviewed and deleted as needed. 5 it was only long after this process that springshare promoted that they could do this on the backend by request. 6 however, it turned out that due to the differences in url structure between classic primo and primo ve that this change was completely unnecessary as the urls did actually needed to be changed again

indicates that less than 17 percent of personal names require cross-references. thus the personal name headings that occur only once but would require authority records because of cross-references could be less than 17 percent. the frequency data combined with reference structure data could have a significant impact on design. out of a total of 695,074 personal names in the authority files associated with the marc bibliographic files examined here, 456,328, or 66 percent, occur only once. of these, fewer than 77,575 would be expected to have cross-references, thus the nameauthority file for personal names could be reduced in size from 695,074 records to 316,321, a 55 percent decrease. if separate authority records are a system requirement, the occurrence figures might then be useful for defining configurations that employ machine-generated provisional records for single-occurrence headings that do not have reference structures or that simplify in other ways the treatment of these headings. these figures may also be useful in making decisions on the addition of retrospective authority records to the automated files. reference 1. william gray potter, "when names collide: conflict in the catalog and aacr2," library resources & technical services 24:7 iwinter 1980). . rlin and oclc as reference tools douglas jones: university of arizona, tucson. the central reference department (social science, humanities, and fine arts) and the science-engineering reference department at the university of arizona library are currently evaluating the oclc and rlin systems as reference tools, to see if their use can significantly improve the effectiveness and efficiency of providing reference service. a significant number of the questions received by our librarians, and presumably by librarians elsewhere, incommunications 201 valve incomplete or inaccurately cited references to monographs, conference proceedings, government documents, technical reports, and monographic serials. if by using a bibliographic utility a librarian can identify or verify an item not found in printed sources, then effectiveness has been improved. once a complete and accurate description of the item is found , it is a relatively simple task to determine whether or not the library has the item, and if not, to request it through interlibrary loan. additionally, if the efficiency of the librarian can be improved by reducing the amount of time required to verify or identify a requested item, then the patron, the library, and, in our case, the taxpayer, have been better served. the promise of nearimmediate response from a computer via an online interactive terminal system is clearly beguiling when compared to the relatively time-consuming searching required with printed sources, which frequently provide only a limited number of access points and often become available weeks, months, or even years after the items they list. we realize, of course, that the promise of instantaneous electronic information retrieval is limited by a variety of factors, and presently we view access to rlin and oclc as potentially powerful adjuncts tonot replacements for printed reference sources. given that rlin and oclc have databases and software geared to known-item searches for catalog card production, our evaluation attempts to document their usefulness in reference service. a preliminary study conducted during the spring semester of 1980-81 indicated that approximately 50 percent of the questionable citations requiring further bibliographic verification could be identified on oclc or rlin. the time required was typically five minutes or less. successful verification using printed indexes to identify the same items ranged from 20 percent in the central reference department to 50 percent in science-engineering. time required per item averaged approximately fifteen minutes. based on our findings, we plan a revised and more thorough test during the fall semester of 1981-82, which will include an assessment of the enhancements to the 202 journal of library automation vol. 14/3 september 1981 rlin system scheduled to be operational this summer. the proposed test will involve eight members of the reference staff-four from each department-who will be trained to search on oclc and rlin. those selected will include both librarians and library assistants who regularly provide reference assistance. the results obtained from such a representative group will better enable us to assess the impact on the whole reference staff should we later decide to fully implement the service. they will be the only ones involved in sampling questions and conducting comparative searches. the test will have two components, the first of which will be a twenty-week period to collect at least 400 sample questions. during their regularly scheduled reference hours, the eight specially trained librarians 'will collect samples of reference requests for materials that, based on the information initially given by the patron, cannot be identified in the card catalog. after checking the catalog, the librarian will then complete the top portion of a two-page selfcarbon form with all of the information that is known about the requested item. then, at regular intervals during the semester, the pages of each form will be separated and distributed to other members of the test staff for batch-mode searching. the manual oclc and rlin searching for each query will be done by different staff members to eliminate crossover effects. each request will be searched on both oclc and rlin with the following information being recorded: 1. date of the material requested (if known). 2. type of material (e.g., conference proceeding). 3. amount of time required to do the search. 4. success or failure of the search. this information will then be cumulated in a statistical table, and the results of each search will be keypunched for computerized analysis using the bmdp (biomedical computer programs) statistical package to determine whether or not effectiveness and efficiency have been improved significantly. in addition, on twenty-four randomly selected days during the semester the trained searchers will count the total number of questions received by them on that day that would have been appropriate to search on rlin or oclc. by using these data it will be possible to extrapolate the potential usefulness of the systems for the entire semester. the second component of the test will be a two-week real-life test during which all questions requiring further verification would be searched immediately on rlin , oclc, and in the appropriate printed sources to compare time required, success rate, and type of material requested. this sort of test would permit the searcher to continue to negotiate with the patron as the search progressed, which is the usual situation. also, this would provide the only opportunity to have the patron judge the value of subject searches done on rlin. if funding is received, preliminary results should be available in early 1982. anyone conducting similar or otherwise relevant studies is asked to contact the author. replicating the washington library network computer system software thomas p. brown: manager of computer services, and raymond deb use: manager of development and library

within twelve hours of making landfall in texas; currently, it appears that the storm will strike directly at the houston– galveston area. houstonians with long memories will be comparing ike to hurricane alicia, which devastated the region in 1983, killing twenty-one and doing $2.6 billion in damage.1 younger residents and/or more recent immigrants to the area will recall tropical storm allison, which though not of hurricane force, lashed the city and much of east texas for two weeks in june 2001, leaving in its wake twenty-three dead, $6.4 billion in losses, and tens of thousands of homes damaged or destroyed.2 and of course, more recently, and much better known to all of us, regardless of where we live, katrina, the “mother of all storms,” killed over eighteen hundred, caused over $80 billion in damage, left huge swaths of new orleans uninhabitable, and created a population exodus with whose effects we are living even to this day.3 common to each of these disasters—and so many others like them—is the fact that they have often wrought terrible damage on libraries in their areas. most of us have probably seen the pictures of the waterand mildewdamaged collections at tulane, xavier, the university of new orleans, and the new orleans public library system. and the damage from these events is long-term or even permanent. i formerly worked at the university of houston (uh), and when i left there in 2006 that institution was still dealing with the consequences of allison’s destruction of uh’s subterranean law library. and now i have to wonder whether uh librarians, faculty, and students might not be facing a similar or even worse catastrophe all over again with ike. ital editorial board member donna hirst has done the profession a great service with her column, “the iowa city flood of 2008: a librarian and it professional’s perspective,” which appears in this issue. her account of how library it folks there dealt with relocations of servers, library staff, and indeed library it staff members themselves should be made required reading for all of us in the field, as well as for senior library administrators. the problem, i think we all secretly know, is that emergency preparedness—also known by its current moniker “business continuity planning” (bc)—and disaster recovery (dr) are not “sexy” subjects. devoting a portion of our always too modest resources of money, equipment, staffing, and time to what is, at best, a sort of insurance against what might happen someday seems inexcusably profligate today. such planning and preparation doesn’t roll out any shiny new services and will win few plaudits from staff or patrons, to say nothing of new resources from those who control our institutional purse strings. buying higher bandwidth equipment for a switching closet is likely to be a far easier sell. that is, until that unthinkable something happens, and your organization is facing (or suffers) a catastrophic loss of it services. note that i didn’t say “equipment” or “infrastructure.” the really important loss will be one of services. “stuff”—in the form of servers, workstations, networks, etc.—all costs money, but ultimately is replaceable. what are not replaceable—at least not immediately—are library services to staff and patrons: access to computing (networking, e-mail, productivity applications, etc.), internet resources, and perhaps most importantly nowadays, the licensed electronic content on which we and our patrons have so come to rely. while the news coverage will emphasize (not without justice, i think) the lost or rescued books in a catastrophic loss situation, what staff and patrons are likely to demand first and loudest will be continuation or restoration of technology-based library services such as e-mail, web presence, web access, and licensed content. lest there be doubt, does anyone recall what drove evacuees into public libraries in the wake of katrina? it was, as much as anything, the desire to locate loved ones and especially the need to seek information and forms for government assistance—all of which required access to networked computing resources. if we have one at all—i suspect that many of us have a dr plan that is sadly dated and that has never been tested. look at it this way: would you roll out a critical and highly visible new web service without careful preparation and testing? yet many of us somehow think that bc or dr is somehow different, with no periodic review or testing required. since we feel we have no resources to devote to bc or dr planning and testing, we excuse our failure to do so by telling ourselves and our administrations that “we can’t really plan for a disaster, since the precise circumstances for which we’re planning won’t be the ones that actually occur.” and so we find ourselves later facing a crisis without any preparation. here at the university of alberta libraries, we’ve been giving the questions of business continuity and disaster recovery a good deal of thought lately. our preexisting dr plan was typical of the sort i’ve described above: outof-date, vanishingly skeletal in its details, without explicit reference or relevance to maintenance and restoration of mission critical services, and of course, untested. impetus for our review has come from several sources. perhaps the most interesting of these has been a university-sponsored bc planning process that embraces a twopronged approach: marc truitt (marc.truitt@ualberta.ca) is associate director, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 4 information technology and libraries | december 2008 n identify and prioritize your organization’s services. working with other constituencies within the library, we have identified and prioritized approximately ten broad services to be maintained or restored in the event of an interruption of our normal business activities. for example, our top priority is the continuation or restoration of access to licensed electronic content (e.g., e-journals, e-books, databases, etc.). our it disaster planning will be informed by and respond to this goal. n identify “upstream” and “downstream” dependencies. we are dependent on others for services so that we can provide our own; thus we cannot offer access to the internet for our users unless campus it provides us with a gateway to off-campus networks. we need to make certain as we plan that campus it is aware of and can provide this service in the scenarios for which we’re planning. by the same token, others are dependent on us for the provision of services critical to their planning: our consortial partners, for example, rely on us for ils, document delivery, and other technology-based services that we need to plan to continue in the event of a disaster. these two facets—services and dependencies—can be expressed as a matrix that is helpful in planning for bc and dr goals that are both responsive to the needs of the organization and achievable in terms of upstream and downstream dependencies. it has been an enlightening exercise. one consequence has been our decision to include, as part of next fiscal year’s budget request, funding to help create a dr site at our library’s remote storage facility, to enable us quickly to restore access to our most critical technology services. in the past, we might have used this annual request as an opportunity to highlight our need for funding to support rolling out some glamorous new service initiative. with this request, though, we are explicitly recognizing that we as an organization need to commit to measures that ensure the continuance in a variety of situations of our existing core services. that’s a major change in mindset for us, as i suspect it would be for many library it organizations. a final interesting aspect of our planning process is that one of the major drivers for the university is a concern about business continuity in the event of a peoplebased disaster. as avian influenza (aka, “bird flu”) has spread beyond the confines of its southeast asian point of origin, worry about how we continue to operate in the midst of a pandemic has been added to the more predictable suite of fires, floods, tornadoes, and earthquakes (okay, not likely in alberta). indeed, pandemic planning is in many ways far more difficult than that for more “normal” disasters. while in many smaller libraries the “it shop” may be comprised of one person in many hats, in larger organizations such as ours (approximately 25 full-time equivalent employees in library it), there tends to be a great deal of specialization. can the webmaster, in the midst of a crisis, support staff workstations? can the help desk technician deduce why our vendor for web of science has suddenly and inexplicably disabled our access? our bc process rules tell us that we should be planning for “three-deep” expertise in all critical areas, since the assumption is that a pandemic might mean that a third or more of our staff would be ill (or worse) at any given time. how many of us offer critical technology services that suffer from that it manager’s ultimate staffing nightmare, the single point of failure? we have no profound answers to these questions, and our planning process is by no means the one that will work for all organizations. but the evidence of katrina, ike, and iowa city is plain: we need to be as prepared as possible for these events. the time to “get religion” about business continuity and disaster recovery is before the unthinkable occurs, not after. are there any of you out there with experiences—either in preparation and planning or in recovery operations—that you would consider sharing with ital readers? we all would benefit from your thoughts and experiences. i know i would! post-ike postscript. ike roared ashore four days ago and it is clear from media coverage since that galveston suffered a catastrophe and houston was badly damaged. reports from area libraries are sketchy and only today beginning to filter out. meanwhile, at the university of houston, the building housing the architecture library lost its roof, and the salvageable portions of its collection are to be relocated to the main m.d. anderson library. references 1.

benefits is it worth upgrading? matus formanek information technology and libraries | september 2023 https://doi.org/10.5860/ital.v42i3.16209 matus formanek (matus.formanek@fhv.uniza.sk) is assistant professor, department of mediamatics and cultural heritage, faculty of humanities, university of zilina, slovakia. © 2023. abstract this study discusses the importance of the dspace open-source software that supports numerous digital libraries and repositories around the world. with the release of dspace version 7, a natural question that arises is whether the new version offers enough new functionalities to motivate system administrators to upgrade. this paper briefly describes the most important changes, including new features and bug fixes, included in dspace 7.4 and prior minor versions. the next parts of this paper explore our estimate that there are several thousand dspace-based systems globally that will likely have to be upgraded in the near future. the main reason for this need is that older versions of dspace (including 5.x) have reached the end of their developer support period or are reaching it in mid-2023. based on our own upgrade experience, we propose suggestions and recommendations on migrating from the previous dspace 6.3-based environment to the new one in a case study that concludes this article. institutional repositories and dspace countless new research papers are being produced around the world daily thanks to the hard work of scientists and research teams. the significance of their research is fully realized when it is shared with other scientific communities. scientists need to disseminate the outputs of their scientific work in an appropriate way. khan and sheikh emphasized in their work that higher education institutions are confronted with the intricate task of preserving and disseminating their intellectual outputs. to effectively address these challenges and ensure open access (oa) to research works, institutional repositories (irs) as information systems emerge as indispensable and substantial tools for safeguarding these scholarly documents in various digital formats.1 in the context of this study, the term institutional repositories refers to digital archives established to collect, preserve, and distribute scholarly and research-related digital scientific outputs within an organization, particularly in academic and research institutions.2 as zervas et al. further stated, institutional repositories were originally developed to showcase their academic work.3 however, valuable digital content must not only be disseminated but also preserved in a reliable way. as khan, khousa, and thelwall noted, digital repositories—institutional repositories included— assume a significant role in facilitating these procedures by furnishing the necessary policy and infrastructure to uphold efficient curation and enduring preservation in contemporary times.4 an appropriate application and other support software is required to create a digital (institutional) repository or digital library. either proprietary or open-source software is used. in our work, we will focus on a particular type of open-source software for supporting digital libraries and repositories. as mapulanga pointed out, the utilization of open-source software has empowered developers globally, granting them the capability to craft tailor-made features and functionalities for the systems.5 this type of software is usually obtained and used for free, which mailto:matus.formanek@fhv.uniza.sk information technology and libraries september 2023 dspace 7 benefits 2 formanek is one of its indisputable advantages. to maintain an objective perspective, it should be acknowledged that implementing and maintaining an open-source operating system and software can entail significant additional costs, despite the potentially low or nonexistent initial acquisition cost of the software. dspace the focus of this paper is an advanced, open-source software called dspace. it is developed to run modern open digital libraries and repositories in academic or other organizations and is supported by a wide community of developers and enthusiasts around the world. dspace provides a robust software framework for durable access to research materials and other valuable digital content, assets, and digital resources, available online, all with an eye on their long-term preservation. for example, dspace is applied to preserve and provide access to academic faculty and students‘ papers, preprints, projects, audio/video visual materials, datasets, or any other important materials.6 in the words of the software developers, the long-term goal of open-source software, which also includes dspace, is, among other things, to ensure that “current and future generations have access to our collective digital heritage.”7 the dspace project was founded in 2002 by hewlett packard and mit. as a result of their close and intensive collaboration, dspace 1.0 was released on november 4, 2002.8 as an advanced software tool for supporting digital libraries and repositories, it thus celebrated its 20th anniversary last year. since its inception, development has progressed rapidly. as the number of active users grew and these users demanded more and better support, it was necessary to establish the dspace foundation—a nonprofit organization that provided technical leadership and administration to support the increasing number of dspace users. the dynamic speed of development has become a characteristic sign of dspace even today. currently, the development of the dspace project is managed by lyrasis and directly supported with in-kind contributions of development resources and financial donations through a community sponsorship program. lyrasis provides leadership and innovation for open technologies that promote durable, persistent access to digital data. this organization collaborates with many academic, scientific, cultural, and technology communities.9 dspace, as software, is available to download for free from the official lyrasis website (https://dspace.lyrasis.org/download/). it may also be freely installed and used, as a low-cost, on-premise software solution. in that case the repository instance is installed on a local server at an institution. alternatively, if preferred, it is possible to host the entire digital repository solution in the cloud as a subscription service for archiving, sharing, and managing content. in our study, we focus primarily on the important steps and principles of setting up and operating a locally run instance of dspace as well as understanding these steps and principles in more depth. currently, dspace is the world's most widely adopted software system for running open archives, libraries, and repositories in general. this claim is supported by numerical data obtained by the globally respected, authoritative registry called open directory of open access repositories (opendoar), which regularly collects and updates relevant metrics each month. dspace has held the largest share for adopted software for open access institutional repositories, approximately 39 percent, among other similar software solutions for several years in a row (see figure 1). https://dspace.lyrasis.org/download/ information technology and libraries september 2023 dspace 7 benefits 3 formanek figure 1. dspace’s dominant position among other similar software solutions.10 we employed shown data to demonstrate the extensive utilization and broad acceptance of dspace in comparison to other alternative systems. additionally, the data retrieved from opendoar (see fig. 1) are supported by equivalent up-to-date data from other authoritative registries such as registry of open access repositories (roar) and re3data. 11 we will consider data from the duraspace registry as supplementary because this registry was created directly by lyrasis (which is the organization that manages dspace’s development).12 in view of this fact, it is reasonable to assume that this registry mainly includes the systems supported by them (except dspace, fedora, and vivo are also systems maintained by lyrasis). thus, in this case, we do not consider the high percentage of dspace-based systems in the registry by lyrasis to be representative. all retrieved data is shown in table 1 below and up to date as of january 10, 2023. table 1. dspace market share. opendoar roar re3data duraspace registry total number of entries 6,002 4,725 3,072 3,703 sum of dspace-based repositories and libraries 2,363 (dspace) + 16 (dspacecris) (39.64%) 2,377 (50.3%) 120 (3.9%) 3,138 (84.7%) as is shown in table 1, except in the re3data registry, dspace is the most popular software. these findings are consistent with the findings of the following research papers and surveys focusing on the topic of open repositories and the widespread popularity of dspace. surveys conducted by information technology and libraries september 2023 dspace 7 benefits 4 formanek several studies found that institutional repositories are more likely to use dspace, fedora, eprints, greenstone, and invenio in this order.13 previous research by ivanović et al. has also found very similar results for dspace adoption by institutional repositories.14 scientific papers written by khan and sheikh and ahammad also highlight the important position of dspace as a world leader in open-source software for digital repositories, or open-source digital library software (osdls). these studies, which only focused on universities in pakistan, showed that dspace is used by 47.6 percent of the digital library or repository systems.15 gurikar and hadagali also investigated the adoption of open-source software and the role of underlying software for institutional repositories within india. based on the data collected, they confirmed that dspace and eprints are the two most popular tools used.16 end of support for older dspace releases released in december 2013, dspace 4.x is a release that remains currently unsupported along with all previous dspace versions since 1.4.0. its support ended in july 2021. the newer major dspace release (5.x) is officially unsupported as of january 1, 2023. this date represents the release end of important security updates. the current major release 6.x (or 6.4) will also see endof-life as of july 1, 2023.17 after this date, bug or other security fixes will no longer be published for these releases. system administrators may worry with this announcement, as explained in the next paragraph. in addition, tim donohue, technical lead for dspace at lyrasis, posted a brief explanation for end of support on the lyrasis wiki pages. the primary reason for dspace 5.x as well as 6.x is as follows: [t]he support period for any major release was usually 3–4 years. the support period for 5.x and 6.x was necessarily extended to allow for the development of 7.x (which is a significant update to the dspace platform). as you may be aware, in the last year, several major open-source libraries have discovered major security vulnerabilities. while dspace 5.x and 6.x were luckily not impacted, those events forced us to reanalyze the ongoing support promised for these releases. because both versions 5.x and 6.x were designed and built on technologies from 6–7 years ago, they have become difficult to maintain. the age of these releases impacts our ability to promise that all future security vulnerabilities can be addressed. these old codebases are showing their age and cannot be made as secure as the 7.x platform. therefore, we highly recommend all institutions begin planning an upgrade to dspace 7.x as soon as reasonably possible.18 dspace migration and upgrade: case studies in current literature worldwide, there are relatively few scientific or conference papers that are in any way related to the issue of migration, modification, or upgrade of a repository/library based directly on dspace. zervas et al. focused on the transformation of a locally running repository into a current research information system (cris), which we consider as an upgrade process.19 bimbe et al. dealt with challenges related to implementation and upgrading a dspace-based institutional repository at the university of zambia. their paper explained the steps taken, the challenges faced, and the process taken to install the software and perform an upgrade to the latest version.20 casados et al. described in their paper an entire workflow of transformation from a legacy repository that was developed in house to a solution based on dspace-cris.21 kawale and vandana published their conference paper relating to the process of installation and customization of a dspace-based institutional repository.22 information technology and libraries september 2023 dspace 7 benefits 5 formanek as these studies show, the process of migration or upgrade is not entirely simple, even in the case of dspace. this paper can help the expert community to raise and partially resolve key issues and assure system administrators that upgrading is a step forward. however, it needs to be carefully considered first. the steps need to be individually explored and tested in the context of each organization’s capabilities. zervas et al. observed that a shared objective is to ensure the continuous alignment of digital repositories with the latest technological advancements. institutional repositories must consistently adjust their mission, objectives, and services to align with those of the university and the community they cater to.23 iowa state university successfully migrated its old digital repository to an open-source dspace 7 instance as early as january 2022. this migration was accomplished following extensive years of research and meticulous planning, with the aim of presenting users with a more streamlined interface, enhanced search functionalities, and a more adaptable repository structure, while preserving all the services and statistical data that users have grown to value.24 given the fact that dspace is currently the most popular software for running digital libraries and repositories, the need or necessity for early upgrades may become an issue or challenge for many systems worldwide. in the following section, we will attempt to sketch the distribution of each dspace version in a production environment. number of dspace-based repositories running worldwide the aim of this section is to approximate the number of repositories worldwide that require upgrading, in accord with the already confirmed information about ending support of the current version. to be able to approximately describe the current state of dspace repositories in the world , we need to at least estimate the relative distribution between the different dspace versions within the repositories deployed in a production environment. we cannot state this information with complete accuracy, but we can rely on the available data online in the repository registries. our survey was conducted to collect data from the duraspace registry maintained by lyrasis. it is the unique registry that also provides information about the version of dspace used for each registered system—other registries (such as opendoar/roar/re3data) do not include this information in their entries. figure 2 is a screenshot with a view of our local departmental repository entry, with the highlighted information about the used major version of dspace. the specific minor version (e.g., 6.3) is not shown. figure 2. the digital repository of the department of mediamatics and cultural heritage in the duraspace registry. on january 10, 2023, in accordance with the methodology, we accessed the open registry duraspace25 and filtered the list of all dspace-based systems from that registry. the only filtering criterion was used technology (dspace) independent of the geolocation of the system, its content , information technology and libraries september 2023 dspace 7 benefits 6 formanek or the access method. as of that date, the duraspace registry displayed and exactly matched 3,138 entries that met the specified conditions. the registry arranged them row by row in a table format. unfortunately, it was not possible to set up a more sophisticated filter so that we only retrieved entries for a particular major version of dspace. furthermore, the entries could be browsed on the site by groups containing only 25 entries. thus, it was not possible to batch export all appropriate entries at once into some structured format like xlsx, csv, etc. we contacted lyrasis technical support by email with a request to export all entries as a single file, but support for this was not provided and the request was unmet. so, we laboriously copied all 3,138 entries from the web into a local ms excel spreadsheet, page by page—126 pages in total. then, we formatted and analyzed the structured data in ms excel. we focused on the last column of the spreadsheet which contained, in most cases but not always, information about the version of dspace that the system or repository was supposedly using. the results are summarized as follows: of the 3,138 registered dspace repositories, only 2,415 entries contained in their metadata the information about the specific dspace version, which represents 76.9 percent of the total number of registered systems. to avoid unwanted bias in the results as much as possible, we continued to work only with this set of repositories that had the used dspace version properly listed in their metadata entries. results are provided in table 2. table 2. dspace’s versions share in duraspace registry. dspace version number of registered systems share in % 1.x 709 29.36% 3.x 198 8.20% 4.x 313 12.96% 5.x 565 23.40% 6.x 613 25.38% 7.x 17 0.70% total 2,415 100.00% based on the provided data and as of january 2023, we observed that only 17 systems declared the usage of the latest major version of dspace 7, labeled as “dspace 7.x.” we suppose that there are certainly many outdated entries in the duraspace registry and elsewhere because this information is only submitted by administrators. lyrasis, as a service provider, does not proactively prompt administrators to continuously update the metadata. moreover, it is possible that many systems already exist but are not registered anywhere. further, many systems may have been—and certainly have been—upgraded to a higher version of dspace but the information on the upgrade has not been corrected in the registry. it is therefore probable that the provided data does not fully reflect the actual real state. in support of this claim, the disproportionately high share (almost 30 percent) of the oldest dspace version (i.e., 1.x) is noted in the total representation. if we completely ignore the probably highly overstated share of older dspace versions (and consider only versions 5.x and newer), the adjusted values are shown in table 3. information technology and libraries september 2023 dspace 7 benefits 7 formanek table 3. estimated share of specific dspace versions in duraspace registry. known dspace version number of registered systems share in % 5.x 565 47% 6.x 613 51% 7.x 17 2% total 1,195 100% based on the data mentioned and evaluated above, we can assume that dspace 7.x is used globally in only approximately 0.70 percent to 2 percent of cases, within the community of organizations using dspace. the most popular versions of dspace are 6.x or even the older 5.x by a considerable margin. in conclusion, we estimate that up to 47 percent of global digital repositories and libraries running dspace are using an outdated version (5.x or older) of this software. if we apply this percentage to data retrieved from the authoritative and more recent opendoar repository, we can reasonably assume that of the 2,379 registered repositories and digital libraries using dspace (see table 1), only around 16 to 48 systems are running on some of the latest major versions of dspace 7.x as of january 2023. most dspace systems—on the order of thousands—are already using the aging version 6.x or even the outdated version 5.x, which is alarming. numerically speaking, we estimate that there are over 2,000 open repositories and libraries based on dspace worldwide waiting to migrate to dspace 7, which is a significant number. we are aware that our results may not be completely accurate and reliable due to the highly probable outdated data in the repositories, but we consider them in kind as indicators or approximations when describing the state of dspace systems in the world at the beginning of 2023. a more rigorous and extensive survey in obtaining accurate numbers would be needed. from an information security perspective, the upgrade/migration to dspace 7.x will help to protect digital objects. the subsequent sections present an introduction to dspace 7 and discuss its principal advantages. dspace 7 development the dspace 7 project began after the open repositories 2015 conference. as a part of the dspace technology roadmap and the strategic plan of lyrasis, the developers, as well as the working groups formed during 2015–2017, focused on the new frontend user interface prototype based on angular as well as on the backend based on the rest api. these key components became the basis for the upcoming dspace 7 version.26 the release of the new major version of dspace 7 (i.e., 7.0) was announced on august 2, 2021, via a press statement also published on the lyrasis website. the statement indicated that dspace version 7.0 brings a number of reasonably radical changes (which will be discussed later in this paper) as reflected in the change to over 1 million lines of code inside the software.27 these changes are so significant in comparison to previous versions of dspace that it is not just only another evolutionary step in its development, but a change in the fundamental paradigms on which dspace is built. information technology and libraries september 2023 dspace 7 benefits 8 formanek atmire, a company that co-develops dspace with lyrasis, has made the first preview release of dspace 7.0 publicly available on its website for testing and feedback purposes since may 20, 2019. as atmire states, dspace 7 has been designed using test-driven development practices, aiming to detect and resolve potential issues at earlier stages of the development process, thereby ensuring more stable releases right from the outset.28 in a lyrasis press release announcing the completion of dspace 7.0, kristi park, dspace governance chair and texas digital library executive director, is quoted saying that the release of the final version of dspace 7.0 was preceded by five beta releases, as well as the subsequent participation of the developer community in a public event called dspace 7 testathon in april 2021. its goal was to report and mend bugs within the latest beta.29 consequently, the collaborative effort involving over 60 community developers, led by lyrasis, atmire, and 4science, led to the development of dspace 7.0. the project received funding support from over 25 institutions worldwide. 30 a more detailed explanation of dspace 7 benefits is offered in the following section. dspace 7.4 benefits the major version of dspace 7, according to the wide developer community, declares many radical changes as well as incorporating completely new features that not only improve the overall level of working with the system, but also add new functionalities and known bug fixes. there are several wiki-style articles published by atmire and lyrasis available on the internet, which draw the attention of system administrators to the most important changes made within dspace 7 and its internal software components.31 however, a detailed, scientifically prepared study focusing on a more comprehensive analysis and deployment of dspace 7, which could appeal to system administrators, has been lacking in the expert community so far. we believe that summarizing and reviewing the new functionalities and the most significant changes in dspace 7, as well as their impacts, will help administrators answer the main questions regarding the potential upgrade of their digital libraries and repositories to the newer major version of dspace 7. in the following paragraphs, we provide an overview analysis of selected major innovations made within dspace 7. all information in our study is based primarily on a synthesis of official information available within the lyrasis.org website. other important sources are technical articles; technically oriented blogs and wikis maintained by experts in the field, especially those written by tim donohue, technical lead for dspace at lyrasis; educational youtube channels by furrukh hussain zai; official dspace tutorials; and webinars published by institutions collaborating with lyrasis.32 we integrated, summarized, and synthesized the obtained information enriching it with our own dspace 7 testing experience. we consider the experience of installing dspace in your own environment (i.e., on site) to be nontransferable. we have actively used dspace since version 4. we also built from the ground up the digital repository of mediamatics and cultural heritage, which we have been maintaining since 2017 and is based on dspace 6.3. for the purposes of this paper, we downloaded and installed the then most up -to-date version of dspace 7.x, which was version 7.4, from october to december 2022, in parallel to the existing legacy repository still based on dspace 6.3. both systems run on the same environmental setup with two virtual machines running ubuntu server 22.04 lts, four cores, 4gb of ram. we were able to compare the two systems on the fly—systemically and architecturally in detail. lyrasis reports that the planned main benefits of dspace 7 have been divided from the very beginning of their phased roll-out into tiers. these tiers are priority lines that contained the information technology and libraries september 2023 dspace 7 benefits 9 formanek separated tasks and milestones according to their level of importance/necessity as identified in a survey conducted among the “dspace steering & leadership members and institutions they represent.” tier 1 represents the highest priority and tier 5 is reserved for low priority. eight out of nine features with the highest priority from tier 1 were implemented into versions 7.1, 7.2, and 7.3. the last available version of dspace, 7.4, adds new functionality from tier 2 and tier 3, so we consider the introduced changes as significant. 33 based on all these new features, it is possible to conclude that dspace 7.4 is already a sufficiently robust, stable, and feature-rich version from a system point of view, which we will describe in more detail. since the first release of dspace 7 (i.e., 7.0), several serious bugs have been fixed. we carry out a detailed comparative analysis and testing against the previous major version of dspace (6.x) based on the numerous implemented changes, and in the following paragraphs, we will present those that are most significant. for clarity of this study, we have divided the list of changes into separate groups: • changes at software system level • advanced integration with other external services • working with digital content • new security features and important bug fixes the release of dspace 7.5, which is a part of the roadmap, occurred in february 2023. it brought the next set of additional functionalities and enhancements within each tier. for example, the adding of item counts for communities and collections was planned. the next minor versions of dspace 7.x (7.6, 7.7, etc.) will be released as needed to ensure that all important milestones within tiers 1 through 4 will be met.34 changes at the software system level this section describes the most significant and important changes that have taken place directly inside dspace 7.x regarding system administration, its internal components, and the installation process. these changes are relevant to each system administrator who is involved in system installation, maintenance, or overall system administration. splitting the system into frontend and backend interfaces the most significant change made within dspace 7.x, and the longest in preparation, is the splitting of the system into a frontend part, based on angular technology, and a full-featured server-side, so called backend, with a completely new redesigned rest api.35 both these components are now installed separately, and as a result, they are linked to each other via references in configuration files.36 according to morris, it is possible to install and run each part (frontend and backend) on a separate server.37 this installation allows dspace to adapt more dynamically to the specific requirements and needs of a given environmental setup, or to scale the required performance more efficiently. the completely new user interface, or frontend, combines the advantages of both now nearly obsolete web interfaces known from dspace 6.x—xmlui and jspui. they no longer meet the required technical criteria for modern dynamic and responsive websites, especially xmlui, which relies on an old, unmaintained apache cocoon framework. the new angular technology used in dspace 7 extends the capabilities and helps improve the user experience: the web interface is fast, natively responsive, and easily customizable and themed via html and css.38 it better supports search engine optimization (seo), which means that inserted digital objects are “easily information technology and libraries september 2023 dspace 7 benefits 10 formanek indexed/searched by google or google scholar ... we verified this by running a series of tests with google scholar team.”39 other significant features of the angular-based frontend interface include improved accessibility and support for web archiving techniques (for example, internet archive harvesting). the web archiving process harvests, collects, and preserves digital content and artefacts from the internet (various web pages, media, blogs, forums, and other online sources) into a maintained archive. dspace 7 integrates with other services, which will be further discussed. angular as a technology, paradoxically, does not even require javascript support to run such applications. as donohue noted, in this case, each user gets “precompiled, static html pages each time they click links or buttons.”40 applications are written in typescript, an enhanced version of javascript supported by microsoft and google.41 due to the advantages, “all users should immediately migrate to and utilize the new angular user interface.” the disadvantage is that there is no migration path from either the xmlui or jspui to the new user interface.42 in other words, upgrading to dspace 7 requires creating and modifying the completely new web user interface, but this can be done by any administrator with slightly advanced knowledge of html and css. the angular-based frontend serves as an interactive graphical extension over the systemically more important backend, which represents the server-side of the dspace architecture. the backend’s most important part is the rest api. all functionalities available through the user interface are now equally achievable through this interface. the complex backend includes tools to support oai-pmh, sword, and rdf in addition to the rest api.43 the original rest api, used since dspace 4.0, was very limited in functionality due to read-only features. the updated and completely modernized rest api allows both read and write functionalities and provides “an easier path towards future integrations with dspace (by other third-party platforms or plugins).”44 in reviewing the rest api, we note that these radical changes have enabled integration with modern and widely deployed services for managing and making scientific content accessible. the old, outdated rest api did not support those features and it is, in short, necessary to update it to allow for further digital library system evolution, “following modern best practices, supporting modern technologies, and easier overall maintenance (maintenance).”45 new admin user interface and its features many changes were implemented in the graphical web interface during the redesign of dspace’s frontend. the main feature noted by users upon login is the new modern admin panel for system administrators, which was added to the interface in dspace 7.0, as shown in figure 3. administrators can run and monitor all workflow processes as well as self-created backend scripts and other actions related to system administration, including various curation tasks, through this so-called admin ui.46 the outputs of these actions are also visible through this graphic interface. administrators can now execute the filter-media script from the admin ui in order to immediately update thumbnails and full-text indexing. in dspace 6.x, this could only be done via the console or command line. 47 information technology and libraries september 2023 dspace 7 benefits 11 formanek figure 3. new admin panel. based on our own experience, it is also possible to edit or search the digital objects more intuitively through the admin ui than in any previous dspace versions. authors placed more emphasis on controlling the environment with the mouse. this is evident in the addition of well known drag-and-drop support or in the newly added so-called quick actions buttons. the authors noted that it is possible to withdraw items or make items private. the process of metadata editing has also been simplified. as donohue pointed out, it “introduces suggest-as-you-type for field name selection of new metadata.”48 in the case of problems that may occur during possible workflows, system administrators can log in as a specific person (type eperson in dspace), allowing them to “debug issues that a specific user is seeing, or do some work on behalf of that user.”49 from the administrator’s and user’s point of view, the control and management of the system is clearly more comfortable and convenient than it was compared to older versions of dspace. batch import and export from admin user interface as of version 7.4, dspace supports direct batch import and export of collections and items to and from a zip file through the admin ui. this workflow could only be done via the console in the past. information technology and libraries september 2023 dspace 7 benefits 12 formanek as a result, the migration process of collections or partial items between dspace systems has become faster. however, it is still not possible to migrate an entire site, or repository, through the web interface in this way. new content detection and analysis framework this feature is not completely new. older versions of dspace have been able to successfully extract textual content from items and index it for fast searching. since dspace 7.3, a new text and metadata extraction filter for full-text indexing has been implemented by using a software tool written in java—apache tika. the new filter is enabled by default and supports all the most popular text formats containing digital media, including adobe pdf, microsoft formats (word, excel, powerpoint), csv, html, rtf, txt, as well as all open document formats.50 new feedback form a new feedback form is now linked in the footer of every page. the system administrator defines “feedback.recipient” conveniently already in local dspace’s config file.51 improved gdpr alignment many system administrators remember the coming of the general data protection regulation (gdpr), especially in the european union, when they had to create and define their own user agreement on all web pages with some cookie preference popup window or banner. it should describe how their data is used through a privacy statement policy. dspace 7 natively integrates this functionality and, therefore, there is no need to create a banner from scratch. now, a cookie preference popup, as is shown in figure 4 below, immediately appears when first accessing the site. by default, it displays on the bottom bar, near the right corner. the system administrator can modify the wording and behavior of the popup. figure 4. a cookie preference popup window. welcome email the introduction email represents an additional advancement in the system. this elective feature has been accessible since version 7.3, allowing the transmission of a welcome email to all recently registered users. this capability can be activated by utilizing the recently introduced mail.welcome.enabled backend configuration in your local.cfg file.52 while a simple functionality, users may be pleased with it from the list of the new dspace 7 features. information technology and libraries september 2023 dspace 7 benefits 13 formanek easier installation process a more significant change within dspace 7.x is the simplification of its installation process in comparison to dspace 6.x. the ability to quickly install dspace 7 via container technology, such as docker, has been added, without requiring much technical knowledge and skills. however, donohue recommends this method only if you just want to try it out quickly for development or test environments.53 from our point of view, for production use cases, a traditional step-by-step installation using a manual is better. as we observed, the dspace installation process requires extra attention and experience with advanced operating system administration, such as windows or unix-like. we recommend following the installation guidelines, which are available thanks to a wide community of experienced users. the community has made available a number of valuable tutorials in text form as well as in video formats.54 we especially recommend the expert youtube channel called ready access to free library and information management technologies by furrukh hussain zai.55 vimal kumar, a digital libraries researcher, has contributed valuable work on the topic of digital libraries through his scientific papers as well as the dspace geek blog, which contains tutorials on this topic.56 we have also successfully used these resources to install a testing instance of dspace 7.4, so we consider these steps as helpful. installing dspace 7.x also requires a recent version of the database system (dbms). this is postgresql 14, at the time of writing.57 donohue provided a cautionary notice to readers regarding the deprecation of oracle database support, with its complete removal scheduled for mid-2023. consequently, all websites should diligently plan for a migration to postgresql.58 in addition to the database system, where the data is stored, a newer version of the tomcat web server (9.x) is also required because it fixes several critical security vulnerabilities. among the software prerequisites, the open jdk v11 and other software components (apache ant, maven, etc.—all are described in dspace’s manual) must be installed.59 compared to older dspace versions, there were no problems with the integration of the various software prerequisites mentioned above when installing dspace 7.x. based on our own experience, we state that webapp deployment is completely seamless within the tomcat 9.x configuration, even for less experienced users, in contrast to dspace 6.x, where we had to use the older tomcat 8 instead of the version 9 due to many persistent app deployment issues. on the other hand, dspace 7.x installation includes a few extra steps. donohue warns that apache solr is now excluded from the dspace installer and must be installed independently as a separate dependency in conjunction with the dspace backend.60 in dspace 6.x’s installer, it was already embedded. solr is one of many important software dependencies used within dspace. it is used in high -traffic websites, which enables features such as full-text searching and real-time indexing. to perform the testing, we installed solr 8.11.1 according to the available tutorials by kumar and system librarian and ran the service on default port nr. 8983 with no problems or errors, as shown in figure 5 below.61 we consider the solr installation simple, and it can be accomplished by even a moderately advanced dspace system administrator. information technology and libraries september 2023 dspace 7 benefits 14 formanek figure 5. solr service running on port 8983. advanced integration with other external services significant improvement had been made with the release of dspace 7.3 in its integration with other services. for this reason, we have decided to dedicate a separate section to describe these changes. the support for importing metadata via external apis, such as orcid, pubmed, sherpa journals or sherpa publishers among others, is considered the most significant and improved features. many integration features included in dspace 7.x are ported from dspace-cris—a separated project maintained by 4science. cris (current research information system) is an extension to dspace that provides a dedicated set of functionalities that give added value to researchers´ work and the repository. it is a picture of the current research activities undergoing in a research organization. the scope of a cris system is very broad as it covers people (researcher profiles, cvs, supervisions), research outcomes (publications, patents, research data), funds, projects, professional activities (invited presentations, peer or editorial reviews, etc.), or management information (metrics, bibliometrics, statistics). the content of a cris is analyzable and reportable. content within a cris system can be easily connected and linked with other content.62 as we see, dspace-cris aims to collect data about research activities and does so through its close integration with other services, which is also its biggest advantage. the dspace-cris is not covered in this paper, although it is also dspace-related. it represents a separate thread of dspace software development, so our focus remains on the relevant new features implemented in dspace 7.x. orcid authentication and synchronization as of dspace 7.3, enhanced orcid authentication and synchronization is implemented. each user with a dspace account, or eperson, can have the dspace researcher profile assigned in the system. it can be synchronized, or initially created, via orcid integration. this feature is turned off by default and must be enabled manually, if needed.63 although the integration with the orcid service has been supported by dspace for a long time, all advanced orcid-related features are fully available in dspace-cris. external lookup of digital object’s metadata while this interesting feature is planned, the functionality is not yet available. it is based on an integration with services providing persistent identifiers (e.g., doi) to enrich an in-progress submission.64 after the implementation, digital content can by directly imported from nine new external services including crossref, scopus, web of science, pubmed europe, cinii, nasa information technology and libraries september 2023 dspace 7 benefits 15 formanek astrophysics data system (ads), vufind.org, scielo.org, and the european patent office (epo). dspace’s official youtube channel also mentioned the support of arxiv in this way.65 support for openaire api the oai-pmh interface has undergone enhancements, allowing for the import of comprehensive funding information (including funder, funder identifier, funding stream, and funding id) from the openaire api when importing project entities (research projects). this functionality has been implemented through a novel external source utilizing the live import from external sources feature.66 single-sign-on (sso) using openid connect (oidc) authentication this entirely new authentication plugin has also been adapted from the dspace-cris project. it enables the support of authentication through various providers like google, microsoft, amazon, and others.67 support for remote handle resolver since dspace 7.4 it is possible to run handle server remotely on a dedicated system. this way may be preferred by some administrators. working with digital content another large group of improvements are changes related to working with digital content, specifically individual files and items. drag and drop support the main submission and workflow features have been redesigned into “a one-page submission process with a drag-and-drop interface & a searchable mydspace.”68 it is shown in figure 6. manual submission of digital objects is therefore slightly easier and faster for all users. figure 6. an item submission. moreover, starting from dspace version 7.4, there is now added support for markdown, html, and mathjax within item abstracts. additionally, all metadata fields now include support for line wrapping.69 information technology and libraries september 2023 dspace 7 benefits 16 formanek extended support for item-level versioning since dspace 7.1, it has been possible to create a new version of an item. versioning is a new functionality to build the history of a digital object. users have the ability to create new versions of an item whenever they make any modifications to it. item versioning is enabled by default.70 support for new configurable entities with relationships dspace 7 supports an optional feature through which relationships between different dspace “configurable entities” (e.g., items) can be captured and expressed, as shown in figure 7. these entities can have configurable relationships to other entities, for example, a set of journal hierarchy entities (journal, volume, issue, publication) and a set of research entities (publication, project, person, orgunit).71 figure 7. item relationships. since dspace 7.3 there has also been support for versioning of configurable entities. it is now possible to create versions of entities that automatically preserve all relationships. when configurable entities are enabled, in the “edit collection” page you can select an entity type (e.g., person, project, journal, etc.) that collection will accept. once configured, this collection will only accept new submissions of that entity type, and will be one of the recommended collections to submitters whenever they start a new submission of that entity type.72 entities can also be imported, including their relationships from another system via the simple archive format. item access status this is an optional feature that must be manually enabled via the new “showaccessstatuses” setting in the config file. subsequently, all item lists can display the status of the item (e.g., “open access,” “restricted,” “metadata only,” “embargoed”). redesigned search box currently, users possess the ability to conduct searches within the header of any web page by activating the magnifying glass icon. subsequently, the search results page has been augmented to incorporate automatic search highlighting, user-friendly drop-down and search filters, as well as the option of thumbnail-based results.73 these advancements are designed to optimize the search process, enabling users to promptly access pertinent information and resources. in comparison to earlier versions of dspace, dspace 7 now offers a more sophisticated and comprehensive search functionality, significantly enhancing its overall usability and accessibility for users. information technology and libraries september 2023 dspace 7 benefits 17 formanek support for video content streaming when enabled, dspace can now stream videos and view images in full screen, using a basic out-ofthe-box media viewer.74 downloading the video is no longer required and users can directly stream from the website, as shown in figure 8. figure 8. video streaming plugin activated in dspace 7. new security features and important bug fixes the last, but no less important, section reviews security aspects: fixing known bugs in the systems involved in running dspace 7 as well as adding some security features. apache log4j/log4shell security vulnerabilities dspace version 7.1.1 fixes a critical vulnerability in the apache log4j library (v2) that allows potential hackers to remotely execute commands and take full control over a system. the log4j library is used to create logs in many java frameworks and applications. it is also used within dspace 7.x. this vulnerability is known as cve-2021-44228.75 according to the national institute of standards and technology (nist), a part of the us department of commerce and one of the oldest physical science laboratories, this vulnerability received the highest possible base score of 10.0 (level: critical). this is therefore an extremely serious problem in terms of systems security.76 we must emphasize that this is a compelling information technology and libraries september 2023 dspace 7 benefits 18 formanek reason to update from older minor versions of dspace 7.x. it is necessary to verify that the server is not running the unpatched version dspace 7.1 in the backend, only if you have tried or worked with dspace 7.0. it is equally important that the server is running apache solr v8.11.1 (or above) as only this version of solr is patched for this vulnerability. fortunately, as donohue stated, dspace 6.x, 5.x, or 4.x (or below) are not vulnerable, as they all use log4j v1 exclusively with a default configuration which is not impacted.77 our recommendation is to exclude all dspace dependencies which relied on log4j v1 as well since log4j v1 is currently at end of life. the ideal solution is a complete migration to dspace 7.4 or above. password authentication security enhancements since dspace 7.4, all users must provide a current password when changing their password. password minimum requirements are now configurable, allowing administrators to require users to create more secure passwords.78 support for google recaptcha as of dspace 7.4, the new user registration form requires completing the google recaptcha feature, as show in figure 9. when activated, this feature provides a robust supplementary safeguard against potential undesired activities, such as large-scale registrations carried out by automated bots utilizing randomly generated or stolen email addresses.79 this feature confirms that the user is indeed a living being. figure 9. google recaptcha integration in dspace 7 web interface. other internal bug fixes and improvements it is highly recommended to always upgrade to the latest minor version (at the time of writing this was dspace 7.6), because the previous versions may contain various vulnerabilities. important improvements and fixed issues are highlighted: • dspace version 7.0 was vulnerable to cve-2021-41189. a community or collection admin could escalate their permissions to become a full administrator. • dspace 7.2 was vulnerable to cve-2022-22965. the vulnerability affects apache spring libraries which are used in java/jdk 9 or above. these libraries are again vulnerable to remote command execution. this vulnerability was scored 9.8 of 10.80 donohue recommends upgrading the dspace backend to version 7.2.1 immediately.81 optionally, information technology and libraries september 2023 dspace 7 benefits 19 formanek upgrade the apache tomcat to version 9.0.62, which provides extra guards against this vulnerability. • since dspace backend version 7.2, indexing and file download performance has been improved, which has contributed to an overall increase in the system experience. numerous other minor bug fixes or accessibility improvements have been implemented. the following section reviews key points of this process, which we faced during the experimental upgrade. the most significant improvements will be described briefly with details in the references. the upgrade of digital repository of mediamatics and cultural heritage—the case study a short history of the system upgrade proof of concept of the digital repository of mediamatics and cultural heritage was already tested during 2017, when it was built on the older version of dspace 6.1. later, in the first half of 2018, we completed the customization of the xmlui environment based on user and expert ux/ui testing. the redesigned web interface was completed and based on dspace 6.2. the system was subsequently launched into production. the repository already contained several dozens of digital objects at that time. it was upgraded to the version 6.3 until the end of 2018. all minor upgrades (6.1, 6.2, 6.3) were successfully carried out using the following procedure framework: 1. a new virtual server with the latest version of the underlying operating system available at the time was installed. we preferred to use ubuntu server with long-term support as a good choice. 2. all necessary software prerequisites and dependencies were installed in the new system environment as well as a default installation of dspace using the appropriate version available at the time according to the instructions in the manual. 3. all system settings, from local.cfg/dspace.cfg and many other configuration files, as well as the entire customized xmlui web interface were copied to the new system. 4. the digital objects were transferred to the empty repository by simply copying the original assetstore82 from the previous system to the new. the next necessary step in the migration process of the repository content was still the transfer of the postgresql database and its content. on the old system we performed a so-called database dump used for dspace; this dump was copied as a single file to the new environment and then restored via the entire restore procedure on the target server. 5. after restarting all system services, the repository started under the same domain name, or ip address, with the same url and the same digital content as it was in the previous repository. the above-mentioned procedure has always been our effort to run the system on the latest (updated) software components (such as apache tomcat, postgresql, java jdk, etc.) as well as on the latest operating system—although dspace, according to the manual, also allows upgrading the version on the remaining system. however, we have preferred a fresh install and then migration of the repository content and settings every time. the installation of new versions of dspace has been carried out without any major difficulties each time using the available manuals and procedures recommended by the experienced professionals, such as vimal kumar, known as system librarian, or furrukh hussain zai. however, the critical point in the mentioned procedure is the migration of content—entire digital objects—between the information technology and libraries september 2023 dspace 7 benefits 20 formanek two dspace instances. when it comes to digital content, it’s not just about the digital files (e.g., pdfs, etc.) located in the assetstore folder. an essential part of a digital object, as defined by the university of california, is also metadata (structural, descriptive, administrative). these metadata are stored in a sql database system (e.g., postgresql). need to upgrade to dspace 7.4 we have considered dspace 6.3 to be fully compliant and to meet our requirements for a long period of time. moreover, in the departmental environment, the web interfaces of the repository (xmlui as well as jpsui, as shown in fig. 10) have been optimized several times towards search engines, so a lot of work has been completed (translation to the slovak language, etc.). figure 10. translated xmlui web interface (on the left) and jspui (on the right). however, with the arrival and dynamic development of the new major version of dspace (7.x) during 2022, we have started to focus intensively on the idea of a necessary upgrade. the currently used underlying operating system (ubuntu server 20.04.5 lts) is becoming obsolete and will also need to be replaced soon. after a thorough information research and considering all the benefits, we decided to try to upgrade the repository to dspace 7.4 in november 2022, using the well-known procedure described above. we installed the latest ubuntu server 22.04.1 lts as well as dspace 7.4: the default backend (rest api) and the angular -based frontend. both components worked correctly in default settings but without any content. the customized settings as well as the whole assetstore were copied/migrated to dspace 7.4 without any issues. we also tried the procedure described in a related post by kumar (2022b). however, a critical problem occurred during the database migration. we assume that the migration from dspace 6.x to dspace 7.4 could not be easily performed using the previously described procedure via a dump and restore of the database, since the structure and content of the database are probably not fully compatible between these versions . or, we have made a mistake of which we were not aware. this issue (incompatibility) resulted in an internal server error message after the database restoration. the migrated digital objects remained inaccessible. thus, the dspace 7.4 instance remained unusable because of the database/system error. to resolve this problem and following the recommendations of the manual (donohue 2022e), we decided to run a migrate command over the imported database as well as the “indexdiscovery -b” command to upgrade the structure of the dspace database and subsequently reindex information technology and libraries september 2023 dspace 7 benefits 21 formanek the entire content of the site, so that the database became compatible with newer versions of dspace. however, this step did not solve the problem. after further unsuccessful attempts, we decided to look intensively for other ways on how to migrate the digital objects. we found that exporting and then importing the entire site structure of the dspace repository via archival information packages (aip) seemed to be potentially suitable and universally applicable. tim donohue recommended this as an alternative approach where you can use the aip export tools to export aips from your old site and then import them into the new site.83 the nature of aips and content migration via aips will be discussed in a following section. aip backup (export) aip is defined in the oais (open archival information system) reference model as an information package that is used to transmit archival objects into a digital archival system, store the objects within the system, and transmit objects from the system. an aip contains both metadata that describes the structure and content of an archived essence and the actual essence itself. it consists of multiple data files that hold either a logically or physically packaged entity.84 according to this definition, aip is used to archive or export digital objects within the dspace system. the ability to work with aip packages has been available in dspace since its inception (version 1.0), so this is not a new feature. therefore, we will utilize it in an appropriate way on an appropriate occasion. in the context of the dspace system, aip may include a single item, collection, community, or an entire site (site aips contain sitewide information). the files with content (such as pdfs), if they exist, are always part of an item’s aip. so, each aip is logically self-contained. this fact implies that it is possible to restore it without the rest of the archive. we can export or restore a single item, collection, or community. aips containing a larger logical object (site, collection, or community) do not include any physical child objects directly in itself (e.g., all items in collection or community) but contain only references (links) to all “child objects” in the metadata structure. if we want to successfully restore a collection, we need to do it only with the corresponding items’ aips. we propose to use the above-mentioned principles in this paper and export the entire site from the original system (dspace 6.3) and transfer this object (aip packages hierarchy) to the new environment (dspace 7.4) via the aip container(s), as shown in figure 11. figure 11. aip import and export process. old dspace 6.3 • aip backup (export) aip containter (hierarchy) • zip files new dspace 7.4 • aip restore (import) information technology and libraries september 2023 dspace 7 benefits 22 formanek each aip is represented fundamentally as a zip file containing metadata (expressed via mets manifest) and, in the case of an item, all related digital content (bitstreams, licenses, and any other associated computer files) too. when exporting an aip, only the latest version of the items is taken from the repository, which is considered as a slight disadvantage of using aip for export. thus, past versions of an item are always lost. unfinished submissions are not described in the aip either. the export command executed over the site root will also invoke the export of all integrated communities and collections. this gives a complete hierarchical export of the entire content of the digital repository including the access permissions to certain collections/communities, or information about the system users (called epersons with their dspace logins and passwords) and user groups. the single item export does not contain any mentioned administrative metadata. in the original system (dspace 6.3), we initiated the recursive command to export the entire hierarchical tree structure of the entire site, starting from its root defined in the command itself: sudo /dspace/bin/dspace packager -d -a -t aip -e spravca.repozitara@fhv.uniza.sk -i 1234/0 /tmp/kmkd/kmkd.zip where: • the prefix “sudo” escalates the privileges when running the command to the administrator level. • the string “/dspace/bin/dspace” represents the absolute path to the executable file located in the specific “dspace-home” directory. • the parameter “packager” triggers export or import of packages. • the “-d” switch modifies the packager settings to default export mode. • the “-a” switch extends the export to all child objects in the structure. this is an important setting if we want to export an entire site, collection, or community. • the “-t aip” switch defines the type of package to be used in the export. we need the aip type. • the “-e spravca.repozitara@fhv.uniza.sk” switch defines the specific user (dspace administrator) who has the privileges to run the export. • the “-i 1234/0” switch defines the top-level root entity from which the export starts. we want to export the entire site, so the root will always be in the form “your-handle-prefix/0”. in our case, we use “1234” as a handle prefix. • the string “/tmp/kmkd/kmkd.zip” represents the absolute path to the folder with the root zip file of the entire site (in our case). this zip file does not exist before the export. it is created when the command was performed. after the command is executed, according to the above-mentioned structure, the export process starts. depending on the number and size of (aip) packages, this action takes an estimation of minutes to tens of minutes. consequently, a hierarchical structure of internally related objects, i.e., zip files (aip archives), is created. as a result, the separate zip files are created side by side and arranged (e.g., by name) in the server’s file system (e.g., in the folder /tmp/kmkd/) after export. the relationships between the aip archives are stored at the metadata level in the associated xml file that is part of each zip archive. the structure of aip/zip packages is shown in figure 12. information technology and libraries september 2023 dspace 7 benefits 23 formanek figure 12. aip hierarchy example. the root package called “yoursite.zip” (“kmkd.zip” in our case) does not physically contain all other zip files of the entire site inside. it only references the aip packages of communities that are located one level lower in the hierarchy (see fig. 12) through xml metadata records. similarly, each community’s package refers to the package (or packages) of the collections that are placed in the hierarchy below it. the physical content files are only part of the item packages which also take up the most disk space. in our case, the export of all objects—284 zip files were created— required a disk space of about 13 gb and took approximately 10 minutes. aip backup (import) all zip files created in the /tmp/kmkd folder were then copied to a new virtual server based on ubuntu 22.04 lts, which already had been running a default installation of dspace 7.4. the new dspace instance already had a precreated administrator (i.e., eperson), under whose account we could start importing the transferred objects. for importing aip packages, we recommend using a command similar to the following: sudo /dspace/bin/dspace packager -r -a -f -t aip -e spravca.repozitara@fhv.uniza.sk -i 1234/0 -o skipifparentmissing=true /home/dkar/kmkd/kmkd.zip where: • “sudo /dspace/bin/dspace packager” has already been explained when exporting. • the “-r” switch initiates the restore process. yoursite.zip community @1234-1.zip collection@12342.zip item@1234-3.zip iitem@1234-4.zip item@1234-5.zip collection@12346.zip community @1234-7.zip collection@12348.zip item@1234-9.zip information technology and libraries september 2023 dspace 7 benefits 24 formanek • the “-f” switch forces so-called force restore. any conflicts with potentially existing data in the target site (if it previously existed) are resolved by overwriting. • the “-t aip” switch defines the package type as aip. • the “-e spravca.repozitara@fhv.uniza.sk” switch defines the administrator account that has the permission to perform the import. • the “-i 1234/0” switch says that we want to import the entire site (therefore that 0) characterized by a particular handle-prefix. we used an unregistered handle prefix “1234” in our case. • the “-o skipifparentmissing=true” switch defines additional import options, telling the packager not to deal with the parent object relationship. since we are already starting the import process from the site’s root (and the root object has no parent), this switch is mainly used when importing the entire site in one step. the above-mentioned command starts the import process over the site root. a hierarchical restore of the entire site will be performed by linking the aip packages at the metadata level. depending on the site size, this process takes tens of minutes to hours of time. in our case, the import process took about 25 minutes. thus, the import process is more time-consuming than the export. when the import process is completed, we highly recommend performing a comprehensive reindexing of the entire repository content. this crucial step is essential for ensuring the accurate visibility of all inserted metadata in the new system. reindexing plays a vital role in maintaining data accuracy, optimizing search engine performance, and ensuring the overall functionality of the system. by accurately reflecting all metadata and content in the new system, reindexing guarantees data consistency and integrity. additionally, it ensures that all data fields are appropriately indexed and searchable, effectively preventing any discrepancies between the migrated data and the search index. reindex the dspace repository content by executing the following command: sudo /dspace/bin/dspace index-discovery consequently, all digital objects should be accessible through the frontend (web) interface. when using an unregistered handle prefix (in our case only the string “1234”), based on our own experience, we must emphasize that the new dspace 7 configuration file (local.cfg) must already contain and define the same handle prefix. it must be identical with the prefix from the original system because the exported aip packages also contain the handle prefix from the original system. this prefix must be recognized by the new system. otherwise, the entire import will fail due to the inability of the system to translate the unknown handle prefix. short discussion on dspace system migration the default web interface (frontend) of our testing instance of dspace 7.4 is shown in figure 13. it also contains items (recent submissions), communities, and collections that we have imported through the aip restore process. information technology and libraries september 2023 dspace 7 benefits 25 formanek figure 13. screenshot of a testing instance in dspace 7.4.85 the complete migration from an older dspace system to a newer or latest version is much more complex and includes far more steps than is possible to describe in this article. in addition to the transfer of the digital objects themselves from one environment to another, system administrators will have to deal with the customization and overall optimization of the web graphical user interface as well as with the start-up and detailed setup of all other dspace components and services, in particular, enabling https in the production environment, setting up oai-pmh, and integrating orcid, which are not covered here due to the scope of the work.86 all these important steps must be kept in mind and considered during migration because their implementation is quite time-consuming. however, we still consider the transfer, i.e., the export and subsequent import of digital objects, to be the key moment of the whole migration. a digital repository without any content (even in the latest version and with advanced features enabled) is a worthless system. information technology and libraries september 2023 dspace 7 benefits 26 formanek conclusion taken together, we have made our own well-reasoned prediction that thousands of dspace systems around the world are likely to soon face the necessity of migrating to the newer version of dspace 7. this is a logical, but technically nontrivial, step that may confuse some system administrators, especially if an unexpected bug or state is detected and the administrator is unable to fix it themself. this paper provides helpful tips to institutions deciding on performing a critical system upgrade and further describes key points and reasons for the migration or upgrade. we have described the most important benefits and functionalities of the new dspace 7.4 version as well as briefly dealt with a case study, where we have given our proposals regarding the transfer of digital objects between two systems with different versions in an alternative, but more universal way, using a practical example. dspace 5 has been end-of-life since january 2023. the support for dspace 6 officially ended in the summer of 2023 as well. we urge system administrators to consider the importance of early upgrading or migrating the systems which they are responsible for due to this end in support for previous versions. administrators must consider these end-of-life statements and the question becomes: what happens if the repositories running dspace 6.x will not be updated by mid-2023? we do not expect a massive failure of open dspace-based repositories, but all systems built on outdated, obsolete, or unpatched software are at a significantly higher risk for potential exploitation of security vulnerabilities by attackers in the online environment. for further detailed research, it would be appreciated if the metadata fields in authoritative registry records like opendoar and others could be extended with a field tracking the specific version of the system used. we also suggest that authoritative registries send periodic communication (e.g., annually) to repository administrators as a prompt or reminder to update the relevant entries they contain. this would prevent outdated entries, links, and other discrepancies that may occur in registers. the upgrading to dspace 7 provides an undisputable number of new advanced and sophisticated features that simplify the overall work with digital entities. in general, dspace 7 represents a significant step forward in the development of software for open digital libraries and repositories on worldwide. it may be considered as a revolution, not only as an evolution in this field. as the most important changes are highlighted and briefly discussed in our study, we recommend trying the latest version of dspace 7, getting to know its new environment, and then developing your own upgrade plan. endnotes 1 kabir khan and arslan sheikh, “open source software adoption for development of institutional repositories

oclc plans to use bisac data transmission protocol and fixed data format in their initial direct transmission effort. however, there are some real problems with these formats relative to library needs. first, the formats do not provide for serials ordering or renewal. second, data fields in the format are fixed length. this is a real problem when ordering esoteric publications. especially since the title and descriptor entries are a single field. obviously there are many items that a library needs to order that cannot be supported by this current standard. oclc and dataphase have representatives on the bisac purchase order subcommittee. this subcommittee is developing a variable length p. 0. format. however, if there is to be real cooperation, and the accompanying economics, we must have more active participation from the library community. the cataloger has the library of congress catalog number (lccn). however, this is inadequate for library acquisitions. the isbn was developed for acquisitions. the isbn identifies the publishers or current distributor, the binding, etc., so necessary for accurate acquisitions. you can order music, maps, recordings, or film by using the isbn. this is providing you order from a publisher that assigns isbns to those materials. it also assumes that you include the isbn on the order. baker and taylor, brodart, random house, and mcgrawhill estimate less than 25 percent of their orders contain an isbn. yankee book, blackwell/north america, and the book house report approximately 10 percent use on orders received. a significant number of these isbns are incorrect, obsolete, or otherwise erroneous. if we are to realize the tremendous economies possible with electronic transmission, we must have greater and more accurate use of the isbn. it is simply uneconomical to transmit all of the data necessary to accurately identify a piece via the cataloging fields and subfields for every order; even if this information were available for ordering. another standard developed by bisac is the standard address number (san). all library vendors, public, academic, and school libraries have been assigned a san. do you know yours? do you know the san of your vendor? these sans are available in your libraries' reference sections, as well as the online name-address directories that accompany the network acquisition systems. if electronic ordering is going to be used most effectively and economically, the san plays an important part. it is not economically efficient to transmit hundreds of characters of address information. the last item that becomes feasible with electronic transmission is order status information. the day is gone when we can afford to keep thousands of dollars encumbered with acquisition pieces that are unavailable. the normal practice of automatic cancel after sixty or ninety days, keeps those monies committed. how much better would it be to know within twentyfour to forty-eight hours of an order that the material was unavailable. those funds, that become more dear each year, could be recommitted to more available items. this would be advantageous to both the vendor, the library and ultimately the library patron. both the bisac invoice and title update formats have potential for use in reporting. it would be better, however, if we could derive a format specific for title status. in closing, i urge you to use the isbn and san; pursue avenues of collective ordering; and lastly, become active in the standards effort. it is the library that ultimately has the most to gain from a cooperative, coordinated, volume-oriented, resource-sharing electronic ordering process. for information relative to bisac transmission formats or bisac membership, write to: book industry systems advisory committee, 160 fifth ave., suite604, new york, ny 10010. for input to bisac purchase order formats, write to: j. k. long, chairman, bisac p.o. subcommittee, c/o oclc, inc., 6565 frantz rd., dublin, oh 43017.

(cti) sells a turnkey backup system based on an apple ii plus microcomputer, with two mini-disk drives using 5\14 " floppy diskettes, a tv monitor, and a switching system connecting the apple to the libs 100 console and terminals. software designed to interface with the clsi system is part of the package. the backup collects and stores data for communications 297 check-ins and checkouts and then dumps them into the database by simulating a terminal when the mini-main-frame is operational again. this requires dedicating a terminal to this process until complete. it can also be used alone as a portable unit for circulation purposes, or with any of the many applesoft packages available, or with an applesoft program of the user's own design. our initial experience in great neck was with a borrowed demonstration system, set up by a sympathetic cti representative on the spur of the moment in tandem with and connected to the main library checkout station's crt laser terminal after several days of downtime. the circulation staff cheered as the familiar prompts appeared on both screens. they used the clsi equipment which they were accustomed to operating and the computer room staff learned to operate the cti system. the ease with which the apple could be transported to different locations in the building and the immediate relief it gave wherever it was connected, sometimes one checkout station, sometimes another, led us to put off deciding on a permanent installation at first. we thought it might be more advantageous to keep it on a rolling cart and use it wherever a terminal was down, or wherever the traffic appeared to be heaviest. we continued in this manner for a while even after both of our own apple systems were delivered. it soon became apparent that the apple and its accompaniments, especially the switching system with its dangling cables, was a nuisance at the checkout counter. people with piles of books or records tended to nudge it dangerously close to the edge or jiggle its connections loose. the circulation staff didn't like waiting until someone from the computer room could be spared to bring up the system, secure the connections, and turn on the apple. also, although the apple is a very reliable instrument which has given us negligible downtime, bumpy rides over various floors , carpets, lintels, and textured tiles occasionally loosened its chips and rendered it, too, inoperative. cti representatives were called in to make a more permanent installation for the apple in our computer room , a simple operation requiring some additional cable. se6 information technology and libraries | june 2008 metadata to support next-generation library resource discovery: lessons from the extensible catalog, phase 1 jennifer bowen the extensible catalog (xc) project at the university of rochester will design and develop a set of open-source applications to provide libraries with an alternative way to reveal their collections to library users. the goals and functional requirements developed for xc reveal generalizable needs for metadata to support a next-generation discovery system. the strategies that the xc project team and xc partner institutions will use to address these issues can contribute to an agenda for attention and action within the library community to ensure that library metadata will continue to support online resource discovery in the future. library metadata, whether in the form of marc 21 catalog records or in a variety of newer metadata schemas, has served its purpose for library users by facilitating their discovery of library resources within online library catalogs (opacs), digital libraries, and institutional repositories. however, libraries now face the challenge of making this wealth of legacy catalog data function adequately within next-generation web discovery environments. approaching this challenge will require: n an understanding of the metadata itself and a commitment to deriving as much value from it as possible; n a vision for the capabilities of future technology; n an understanding of the needs of current (and, where possible, future) library users; and n a commitment to ensuring that lessons learned in this area inform the development of both future library systems and future metadata standards. the university of rochester ’s extensible catalog (xc) project will bring these various perspectives together to design and develop a set of open-source, collaboratively built next-generation discovery tools for libraries. the xc project team seeks to make the best possible use of legacy library metadata, while also informing the future development of discovery metadata for libraries. during phase 1 of the xc project (2006–2007), the xc project team created a plan for developing xc and defined the goals and initial functional requirements for the system. this paper outlines the major metadatarelated issues that the xc project team and xc partner institutions will need to address to build the xc system during phase 2. it also describes how the xc team and xc partners will address these issues, and concludes by presenting a number of issues for the broader library community to consider. while this paper focuses on the work of a single library project, the goals and functional requirements developed for the xc project reveal many generalizable needs for metadata to support a next-generation discovery system.1 the metadata-related goals of the xc project—to facilitate the use of marc metadata outside an integrated library system (ils), to combine marc metadata with metadata from other sources in a single discovery environment, and to facilitate new functionality (e.g., faceted browsing, user tagging)—are very similar to the goals of other library projects and commercial vendor discovery software. the issues described in this paper thus transcend their connection to the xc project and can be considered general needs for library discovery metadata in the near future. in addition to informing the library community about the xc project and encouraging comment on that work, the author hopes that identifying and describing metadata issues that are important for xc—and that are likely to be important for other projects as well—will encourage the library community to set these issues as high priorities for attention and action within the next few years. n the extensible catalog project the university of rochester’s vision for the extensible catalog (xc) is to design and develop a set of open-source applications that provide libraries with an alternative way to reveal their collections to library users. xc will provide easy access to all resources (both digital and physical collections) and will enable library content to be revealed through other web applications that libraries may already be using. xc will be released as open-source software, so it will be available for free download, and libraries will be able to adopt, customize, and extend the software to meet their local needs. the xc project is a collaborative effort between partner institutions that will serve a variety of roles in its development. phase 1 of the xc project, funded by the andrew w. mellon foundation and carried out by the university of rochester river campus libraries between april 2006 and june 2007, resulted in the creation of a project plan for the development of xc. during xc phase 1, the xc project team recruited a number of other institutions that will serve as xc partners and who have agreed to contribute resources toward building and implementing xc during phase 2. xc phase 2 (october 2007 through jennifer bowen (jbowen@library.rochester.edu) is director of metadata management at the university of rochester river campus libraries, new york, and is co-principal investigator for the extensible catalog project. metadata to support next-generation library resource discovery | bowen 7 june 2009) is supported through additional funding from the andrew w. mellon foundation, the university of rochester, and xc partners. during phase 2, the xc project team, assisted by xc partners, will deploy the xc software and make it available as open-source software.2 through its various components, the xc system will provide a platform for local development and experimentation that will ultimately allow libraries to manage and reveal their metadata through a variety of web applications such as web sites, institutional repositories, and content management systems. a library may choose to create its own customized local interface to xc, or use xc’s native user interface “as is.” the native xc interface will include web 2.0 functionality, such as tagging and faceted browsing of search results that will be informed by frbr (functional requirements for bibliographic records)3 and frad (functional requirements for authority data)4 conceptual models. the xc software will handle multiple metadata schemas, such as marc 215 and dublin core,6 and will be able to serve as a repository for both existing and future library metadata. in addition, xc will facilitate the creation and incorporation of user-created metadata, enabling such metadata to be enhanced, augmented, and redistributed in a variety of ways. the xc project team has designed a modular architecture for xc, as shown in the simplified schematic in figure 1. xc will bring together metadata from a variety of sources (integrated library systems, digital repositories, etc.), apply services to that metadata, and display it in a usable way in the web environments where users expect to find it.7 xc’s architecture will allow institutions that implement the software to take advantage of innovative models for shared metadata services, which will be described in this paper. n xc phase 1 activities during the now-completed xc phase 1, the xc project team focused on six areas of activity: 1. survey and understand existing research on user practices. 2. gauge library demand for the xc system. 3. anticipate and prepare for the metadata requirements of the new system. 4. learn about and build on related projects. 5. experiment with and incorporate useful, freely available code. 6. build a community of interest. the xc project team carried out a variety of research activities to inform the overall goals and high-level functional requirements for xc. this research included a literature search and ongoing monitoring of discussion lists and blogs, to allow the team to keep up with the most current discussions taking place about next-generation library discovery systems and related technologies and projects.8 the xc team also consulted regularly with prospective partners and other knowledgeable colleagues who are engaged in defining the concept of a next-generation library discovery system. in order to gauge library demand for the xc system, the team also conducted a survey of interested institutions.9 this paper reports the results of the third area of activity during xc phase 1—anticipating and preparing for the metadata requirements of the new system—and looks ahead to plans to develop the xc software during phase 2. n xc goals and metadata functional requirements the goals of the xc project have significant implications for the metadata functionality of the system, with each goal suggesting specific high-level functional requirements for how the system can achieve that particular goal. the five goals are: n goal 1: provide access to all library resources, digital and non-digital. n goal 2: bring metadata about library resources into a more open web environment. n goal 3: provide an interface with new web functionality such as web 2.0 features and faceted browsing. n goal 4: conduct user research to inform system development. n goal 5: publish the xc code as open-source software. figure 1. xc system diagram 8 information technology and libraries | june 2008 an overview of each xc goal and its related high-level metadata requirements appears below. each requirement is then discussed in more detail, with a plan for how the xc project team will address that requirement when developing the xc software. n goal 1: provide access to all library resources, digital and non-digital working alongside a library’s current integrated library system (ils) and its other web applications, xc will strive to bring together access to all library resources, thus eliminating the data silos that are now likely to exist between a library’s opac and its various digital repositories and commercial databases. this goal suggests two fairly obvious metadata requirements (requirements 1 and 2). requirement 1—the system must be capable of acquiring and managing metadata from multiple sources: ilss, digital repositories, licensed databases, etc. a typical library currently has metadata pertaining to its collections residing in a variety of separate online systems: marc data in an ils, metadata in various schemas in digital collections and repositories, citation data in commercial databases, and other content on library web sites. a library that implements xc may want to populate the system with metadata from several online environments to simplify access to all types of resources. to achieve goal 1, xc must be capable of acquiring and managing metadata from all of these sources. each online environment and type of metadata present their own challenges. repurposing marc data repurposing marc metadata from an existing ils will be one of the biggest metadata tasks for a next-generation discovery system such as xc. in planning xc, we have assumed that most libraries will keep their current ils for the next few years or perhaps migrate to a newer commercial or open-source ils. in either case, most libraries will likely continue to rely on an ils’s staff functionality to handle materials acquisition, cataloging, circulation, etc. for the short term. relying upon an ils as a processing environment does not, however, mean that a library must use the opac portion of that ils as its means of resource discovery for users. xc will provide other options for resource retrieval by using web services to interact with the ils in the background.10 to repurpose ils metadata and enable it to be used in various web discovery environments, xc will harvest a copy of marc metadata records from an institution’s ils using the open archives initiative protocol for metadata harvesting (oai-pmh).11 using web services and standard protocols such as oaipmh offers not only a short-term solution for reusing metadata from an ils, but can also be used in both the shortand long-term to harvest metadata from any system that is oai-pmh harvestable, as will be discussed further below. while harvesting metadata from existing systems into xc creates duplication of metadata between an ils and xc, this actually has significant benefits. xc will handle metadata updates through automated harvesting services that minimize additional work for library staff, other than for setting up and managing the automated services themselves. the internal xc metadata cache can be easily regenerated from the original repositories and services when necessary, such as to enable future changes to the internal xc metadata schema. the xc system architecture also makes use of internal metadata duplication among xc’s components, which allows these components to communicate with each other using oaipmh. this built-in metadata redundancy will also enable xc to communicate with external services using this standard protocol. it is important to distinguish the deliberate metadata redundancies built into the xc architecture from the type of metadata redundancies that have been singled out for elimination in the library of congress working group on the future of bibliographic control draft report (recommendation 1.1)12 and previously in the university of california (uc) libraries bibliographic services task force’s final report.13 these other “negative” redundancies result from difficulties in sharing metadata among different environments and cause significant additional staff expense for libraries to enrich or recreate metadata locally. xc’s architecture actually solves many of these problems by facilitating the sharing of enriched metadata among xc users. xc can also adapt as the library community begins to address the types of costly metadata redundancies mentioned in the above reports, such as between the oclc worldcat database14 and copies of that marc data contained within a library’s ils, because xc will be capable of harvesting metadata from any source that uses a standard api.15 metadata from digital repositories and other free sources xc will harvest metadata from various digital collections and repositories, using oai-pmh, and will maintain a copy of the harvested metadata within the xc metadata cache, as shown in figure 1. the metadata services hub architecture provides flexibility and possible economy for xc users by offering the option for multiple xc institutions to share a single metadata hub, thus allowing participating institutions to take full advantage of the hub’s capabilities to aggregate and augment metadata from multiple sources. while the procedure for harvestmetadata to support next-generation library resource discovery | bowen 9 ing metadata from an external repository is not technologically difficult in itself, managing the flow of metadata coming from multiple sources and aggregating that metadata for use in xc will require the development of sophisticated software. to address this, the xc project team is partnering with established experts in bibliographic metadata aggregation to develop the metadata services portion of the xc architecture. the team from cornell university that has developed the software behind the national science digital library’s metadata management system (nsdl/mms)16 is advising the xc team in the development of the xc metadata services hub, which will be built on top of the basic nsdl/mms software. the xc metadata services hub will coordinate metadata services into a reusable task grouping that can be started on demand or scheduled to run regularly. this xc component will harvest xml metadata and combine metadata records that refer to equivalent resources (based on uniform resource identifier [uri], if available, or other unique identifier) into what the cornell team describes as a “mudball.” each mudball will contain the original metadata, the sources for the metadata, and the references to any services used to combine metadata into the mudball. the mudball may also contain metadata that is the result of further automated processing or services to improve quality or to explicitly identify relationships between resources. hub services could potentially record the source of each individual metadata statement within each mudball, which would then allow a metadata record to be redelivered in its original or in an enriched form when requested.17 by allowing for the capture of provenance data for each data element, the hub could potentially provide much more granular information about the origin of metadata—and much more flexibility for recombining metadata—than is possible in most marcbased environments. after using the redeployed nsdl/mms software as the foundation for the xc metadata hub, the xc project team will develop additional hub services to support xc’s functional requirements. xc-specific hub services will accommodate incoming marc data (including marc holdings data for non-digital resources); basic authority control; mappings from marc 21, marcxml,18 and dublin core to an internal xc schema defined within the xc application profile (described below); and other services to facilitate the functionality of the xc user environments (see discussion of requirement 5, below). finally, the xc hub services will make the metadata available for harvesting from the hub by the xc client integration applications. metadata for licensed content for a next-generation discovery system such as xc to provide access to all library resources, it will need to provide access to licensed content, such as citation data and full-text databases. metasearch technology provides one option for incorporating access to licensed content into xc. unfortunately, various difficulties with metasearch technology19 and usability issues with some metasearch products20 make metasearch technology a less-than-ideal solution. an alternative approach would bring metadata from licensed content directly into a system such as xc. the metadata services hub architecture for xc is capable of handling the ingest and processing of metadata supplied by commercial content providers by adding additional services to handle the necessary schema transformations and to control access to the licensed content. the more difficult issue with licensed content may be to obtain the cooperation of commercial vendors to ingest their metadata into xc. pursuing individual agreements with vendors to negotiate rights to ingest their metadata is beyond the original scope of xc’s phase 2 project. however, the xc team will continue to monitor ongoing developments in this area, especially the work of the ethicshare project, which uses a system architecture very similar to that of xc.21 it remains our goal to build a system that will facilitate the inclusion of licensed content within xc in situations where commercial providers have made it available to xc users. requirement 1 summary when considering needed functionality for a next-generation discovery system, the ability to ingest and manage metadata from a variety of sources is of paramount importance. unlike a current ils, where we often think of metadata as mostly static unless it is supplemented by new, updated, and deleted records, we should instead envision the metadata in a next-generation system as being in constant motion, moving from one environment to another and being harvested and transformed on a scheduled basis. the metadata services hub architecture of the xc system will accommodate and facilitate such constant movement of metadata. requirement 2—the system must handle multiple metadata schemas. an extension of requirement 1 will be the necessity for a next-generation system such as xc to handle metadata from multiple schemas, as the system harvests those schemas from various sources. library metadata priorities as a part of the xc survey of libraries described earlier in this paper, the xt team queried respondents about what metadata schemas they currently use or plan to use in the near future. many responding libraries indicated that they expect to increase their use of non–marc 21 metadata within the next three years, although no library indicated the intention to completely move away from 10 information technology and libraries | june 2008 marc 21 within that time period. nevertheless, the idea of a “marc exit strategy” has been discussed in various circles.22 the architecture of xc will enable libraries to move beyond the constraints of a marc-based system without abandoning their ils, and will provide an opportunity for libraries to stage their “marc exit strategy” in a way that suits their purposes. libraries also indicated that they plan to move away from homegrown schemas toward accepted standards such as mets,23 mods,24 mads,25 premis,26 ead,27 vra core,28 and dublin core.29 several responding libraries plan to move toward a wider variety of metadata schemas in the near future, and will focus on using xmlbased schemas to facilitate interoperability and metadata harvesting. to address the needs of these libraries in the future, xc’s metadata services will contain a variety of transformation services to handle a variety of schemas. taking into account the metadata schemas mentioned the most often among survey respondents, the software developed during phase 2 of the xc project will support harvested metadata in marc 21, marcxml, and dublin core (including qualified dublin core).30 metadata crosswalks and mapping one respondent to the xc survey offered the prediction that “reuse of existing metadata and transformation of metadata from one format to another will become commonplace and routine.”31 xc’s internal metadata transformations must be designed with this in mind, to facilitate making these activities “commonplace and routine.” fortunately, many maps and crosswalks already exist that potentially can be incorporated into a next-generation system such as xc.32 the metadata services hub architecture for xc can function as a standard framework for applying a variety of existing crosswalks within a single, shared environment. following “best practices” for crosswalking metadata, such as those developed by the digital library federation (dlf),33 will be extremely important in this environment. as the dlf guidelines describe, metadata schema transformation is not as straightforward as it might first appear to be. while the dlf guidelines advise always crosswalking from a more robust schema to a simpler one, sometimes in a series of steps, such mapping will often result in “dumbing down” of metadata, or loss of granularity. this is a particularly important concern for the xc project because a large percentage of the metadata handled by xc will be rich legacy marc 21 metadata, and we hope to maintain as much of that richness as possible within the xc system. in addition to simply mapping one data element in a schema to its closest equivalent in another, it is essential to ensure that the underlying metadata models of the two schemas being crosswalked are compatible. the authors of the framework for a bibliographic future draft document define multiple layers of such models that need to be considered,34 and offer a general highlevel comparison between the frbr data model35 and the dcmi (dublin core metadata initiative) abstract model (dcam).36 more detailed comparisons of models are also taking place as a part of the development of the new metadata content standard, resource description and access (rda).37 the developers of rda have issued documents offering a detailed mapping of rda elements to rda’s underlying model (frbr)38 and analyzing the relationship between rda elements, the dcmi abstract model, and the metadata framework.39 as a result of a meeting held april 30–may 1, 2007, a joint dcmi/rda task group is now undertaking the collaborative work necessary to carry out the following tasks: n develop an rda element vocabulary. n develop an rda/dublin core application profile based on frbr and frad. n disclose rda value vocabularies using rdf/ rdfs/skos.40 these efforts hold much potential to provide a more rigorous way to communicate about metadata across multiple communities and to increase the compatibility of different metadata schemas and their underlying models. such compatibility will be essential to enabling the functionality of future discovery systems such as xc. an xc metadata application profile the xc project team will define a metadata application profile for xc as a way to document decisions made about data elements, content standards, and crosswalking used within the system. the use of an application profile can facilitate metadata migration, harvesting, and other automated processes, and presents an approach to metadata that is more flexible and responsive to local needs than simply adopting someone else’s metadata guidelines.41 application profiles facilitate the use of multiple schemas because elements can be selected for inclusion from more than one existing schema, or additional elements can be created and defined locally.42 because the xc system will incorporate harvested metadata from a variety of sources, the use of an application profile will be essential to support xc’s complex system requirements. the dcmi community has published guidelines for creating a dublin core application profile (dcap), which is defined more specifically as: [a] form for documenting which terms a given application uses in its metadata, with what extensions or adaptations, and specifying how those terms relate both to formal standards such as dublin core as well as to less formally defined element sets and vocabularies.43 metadata to support next-generation library resource discovery | bowen 11 the announcement of plans to develop an rda/ dublin core application profile illustrates the important role that application profiles are beginning to take to facilitate the interoperability of metadata schemas. the planned rda/dc application profile will “translate” rda into a standard structure that will allow it to be related more easily to other metadata element sets. unfortunately, the rda/dc application profile will likely not be completed in time for it to be incorporated into the first release of the xc software in mid-2009. nevertheless, we intend to use the existing definitions of rda elements to inform the development of the xc application profile.44 this will allow us to anticipate any future incompatibilities between the rda/dc and the xc application profiles, and ensure that xc will be wellpositioned to take advantage of rda-based metadata when rda is implemented. this process may have the reciprocal benefit of also informing the developers of rda of any rda elements that may be difficult to implement within a next-generation system such as xc. the potential value of rda to the xc project—in terms of providing a consistent approach to bibliographic and authority metadata and facilitating frbr-related user functionality—is very significant. it is hoped that at some point xc can become an early adopter of rda and provide a mechanism through which libraries can move their legacy marc 21 metadata into a system that is compatible with an emerging international metadata standard. n goal 2: bring metadata about library resources into a more open web environment xc will reveal library metadata not only through its own separate interface (either the out-of-the-box xc interface or an interface designed by the local library), but will also allow library metadata to be revealed through other web applications. the latter approach will bring library resources directly to web locations that library users are already visiting, rather than attempting to entice users to visit an additional library-specific web location. making library metadata work effectively in the broader web environment (outside the well-defined boundaries of an ils or repository) will require the following requirements 3 and 4: requirement 3—metadata must conform to the standards of the new web environments as well as to that of the system from which it originated. achieving requirement 3 will require library metadata in future systems to perform a dual function: to conform to both existing library standards as well as to web standards and conventions. one way to achieve this is to ensure that the two types of standards themselves are compatible. coyle and hillmann have argued persuasively for changes in the direction of rda development to allow metadata created using rda to function in the broader web environment. these changes include the need to follow a clearly refined, high-level metadata model, to create data elements that can be manipulated by machines, and to move toward the use of uris instead of textual identifiers.45 after the announcement of the outcomes of the rda/dc data modeling meeting, the two authors are considerably more optimistic about rda functioning as a standard within the broader web environment.46 this discourse concerning rda shows but a piece of the process through which long-established library metadata standards need to be reexamined to make library metadata understandable to both humans and machines on the web. moving away from aacr2 toward rda, and ultimately toward incorporating standard web conventions into library metadata, can be a difficult process for those involved in creating and maintaining library standards. nevertheless, transforming library metadata standards in this way is essential to fulfill the requirements necessary for next-generation library discovery systems. requirement 4—metadata must function effectively within the new web environments as well as within the system from which it originated. not only must metadata for a next-generation system follow the conventions and standards used in the broader web, but the data also needs to be able to function effectively in a broader web environment. this is a slightly different proposition from requirement 3, and will necessitate testing the metadata standards themselves to ensure that they enable library metadata to function effectively. the xc project will provide direct experience with using library metadata in two types of web environments: content management systems and learning management systems. library metadata in a content management system as shown in the xc architecture diagram in figure 1, the xc project team will build one of the primary user environments for xc on top of the open-source content management system, drupal.47 the xc drupal module will allow us to respond to many of the needs expressed by libraries in their responses to the xc survey48 by supplying: n a web application server with a back-end database; 12 information technology and libraries | june 2008 n a user interface with web 2.0 features; n library-controlled web pages that will treat library metadata as a native data type; n a metadata interface for enhancing or correcting metadata in the system; and n an administrative interface. the xc team will bring library metadata into the drupal content management system (cms) as a native content type within that environment, creating a drupal “node” for each metadata record. this will allow xc to take advantage of many native features of the drupal cms, such as a taxonomy system.49 building xc interfaces on top of the drupal cms will also give us an opportunity to collaborate with partner libraries that are already active participants in the drupal user community. xc’s architecture will allow the possibility of developing additional user environments on top of other content management systems. bringing library metadata into these new environments will provide many new opportunities for libraries to manipulate their metadata and present it to users without being constrained by the limitations of the current generation of library systems. such opportunities will then inform the future requirements for library metadata in such environments. library metadata in a learning management system figure 1 illustrates two examples of xc user environments through learning management systems: xc interfaces to both the blackboard learning system50 and sakai.51 much exciting work is being done at other institutions to bring library content into these web applications.52 xc will build on projects such as these to reveal library metadata for non-licensed library resources from an ils through learning management systems. specifically, we plan to develop the capability for libraries to make the display of library metadata context-sensitive within the learning management system. for example, searching or browsing on a page for a particular academic course could be configured to reflect the subject area of the course (e.g., chemistry) and automatically present library resources related to that subject.53 this capability will build upon the experiences gained by the university of rochester through its work to develop its “course resources” system.54 such xc functionality will be integrated directly into the learning management system, rather than simply providing a link out to a separate library system. again, we hope that our efforts to bring library metadata into these new environments will encourage libraries to engage in further work to integrate library resources into broader web environments and inform future requirements for library metadata in these environments. n goal 3: provide an interface with new web functionality such as web 2.0 features and faceted browsing new functionality for users will require that metadata fulfill more sophisticated functions in a next-generation system than it may have done in an ils or repository, in order to provide more intuitive searching and navigation. the system will also need to capture and incorporate metadata generated through tagging, user-contributed reviews, etc. such new functionality creates the need for requirements 5 and 6. requirement 5—metadata must support functionality to facilitate intuitive searching and navigation, such as faceted browsing and frbrinformed results groupings. enabling faceting and clustering much research has already been done regarding the design of faceted search interfaces in general.55 when considered along with user research conducted at other institutions56 and to be conducted during the development of xc, this data provides a strong foundation for the design of a faceted browse environment. the xc project team has already gained firsthand experience with developing faceted browsing through the development of the “c4” prototype interface during phase 1 of the xc project.57 to enable faceting within xc, we will also pay particular attention to what others have discovered through designing faceted interfaces on top of legacy marc 21 metadata. specific lessons learned from those involved with north carolina state university’s endeca-based catalog,58 vanderbilt university’s primo implementation,59 and plymouth state university’s scriblio system60 provide valuable guidance for the xc project team as we design facets for the xc system. ideally, a mechanism should be developed to enable these discoveries to feed back into the development of metadata and encoding standards, so that changes to existing standards can be considered to facilitate faceting in the future. several new system implementations have used library of congress subject headings (lcsh) and lc subdivisions from marc 21 records as the basis for deriving facets. the xc “c4” prototype interface provides facets for topic, genre, and region that are based simply upon one or more marc 21 6xx tags.61 north carolina state university’s endeca-based system has enabled facets for topic, genre, region, and era using lcsh subdivisions as well, but this has necessitated a “massive cleanup” of subdivisions, as described by charley pennell.62 oclc’s fast (faceted application of subject terminology) project may provide another option for enabling such facets.63 a library could populate its marc 21 data with fast headings, based metadata to support next-generation library resource discovery | bowen 13 upon the existing lcsh in the records, and then use the fast headings as the basis for generating facets. it remains to be seen whether fast will offer significant benefit over lcsh itself when it comes to faceting, however, since fast headings are generated directly from lcsh. while marc 21 metadata has some known difficulties where faceting and clustering are concerned (such as those involving lcsh), the xc system will encounter additional difficulties when implementing these technologies with less robust metadata schemas such as simple dublin core, and especially across metadata from a variety of schemas. the development of web services to augment batches of metadata records in an automated manner holds some promise for improving the creation of facets from other metadata schemas. within the xc system, such services could be added to the metadata services hub and run against ingested metadata. while designing extensive services of this type is beyond the scope of the next phase of xc software development, we will encourage others to develop such services for xc. another (but much less desirable) approach to augmenting metadata is for a metadata specialist to manually edit one record or group of records. the xc cataloging interface, built within the drupal cms, will allow recordby-record editing of metadata when necessary. while we see this editing interface as essential functionality for xc, we anticipate that libraries will want to use this feature sparingly. in many cases it will be preferable to correct or augment metadata within its original repository (e.g., the institution’s ils) and then re-harvest the corrected metadata, rather than correcting it manually within xc itself. because of the expense of manual metadata augmentation and correction, libraries will be well-advised to rely upon insights gained through user research to assess the value of this type of work. for example, a library might decide to edit individual metadata records only when the correction or augmentation will support specific system functionality that is of high priority for the institution’s users. implementing frbr results groupings to incorporate logical groupings of search results based upon the frbr64 and frad65 data models over sets of diverse metadata within xc, we will encounter similar difficulties that we face with faceting and clustering. various analyses of the marc 21 formats have dealt extensively with the relationship between frbr and marc 21,66 and others have written specifically about methodology for frbrizing a marc-based catalog.67 in addition, various tools and web services are available that can potentially facilitate this process.68 even with this extensive body of work to draw upon, however, the success of our implementation of frbr-based functionality will depend upon both the quality and completeness of the system’s metadata. metadata in xc that originated as dublin core records may need significant augmentation to be incorporated effectively into frbrized results displays. to maximize the ability of the system to support frbr/frad results groupings, we may need to supplement automated grouping of resources with a combination of additional services for the metadata services hub, and with cataloger-generated metadata correction and augmentation, as described above.69 the xc team will use the results of user research carried out during the next phase of the xc project to inform our decision-making regarding what frbr-informed results grouping users find helpful, and then assess what specific metadata augmentation services are needed for xc. providing frbr-informed groupings of related records in search results will be easier when the underlying metadata incorporates principles of authority control. of course, the vast majority of the non-marc metadata that will be ingested into xc will not be under authority control. again, this situation suggests the need for additional services or functionality to improve existing metadata within the xc metadata hub, the xc cataloging interface, or both. as an experiment in developing services to facilitate authority control, the xc project team carried out a pilot project in partnership with a group of software engineering students from the rochester institute of technology (rit) during phase 1 of xc. the rit students designed a basic name access control tool that can be used across disparate metadata schemas in an environment such as xc. the tool can ingest marc 21 authority and bibliographic records as well as dublin core records, provide automated matching, and facilitate a cataloger’s handling of problem reports.70 the xc project team will implement the automated portion of the tool as a web service within the xc hub, and the “cataloger facilitation” portion of the tool within the xc cataloging user interface. institutions that use xc can then incorporate additional tools to facilitate authority control into xc as they are needed and developed. in addition to providing a test case for developing xc metadata services, the rit pilot project proved valuable by providing an opportunity for student software developers and catalogers to discuss the functional requirements of a cataloging tool. not only did the experience enable the developers to understand the needs of the system’s intended users, but it also presented an opportunity for the engineering students to demonstrate technological possibilities that the catalogers—who work almost exclusively with legacy ils technology—may not have envisioned before participating in the project. requirement 6—the system must manage usergenerated metadata resulting from user tagging, submission of reviews, etc. because users now expect web-based tools to offer web 2.0 functionalities, the xc project has as one of its basic 14 information technology and libraries | june 2008 goals to incorporate these functionalities into xc’s user environments. the results of the xc survey rank tools to support the finding, gathering, use, and reuse of scholarly content (e.g., rss feeds, blogs, tagging, user reviews) eighth out of a list of twenty new desirable opac features.71 we expect to learn much more about the usefulness of web 2.0 technology within a next-generation system through the user research that we will carry out during phase 2 of the xc project. the xc system will capture metadata generated by users from any one of the system’s user environments (e.g., drupal-based interface, learning management system integration) and harvest it back into the system’s metadata services hub for processing.72 the xc application profile will incorporate user-generated metadata, mapped into its own carefully defined metadata elements. this will allow us to capture and manage this metadata as discrete content, without inadvertently mixing it with other metadata created by library staff or ingested from other sources. n goal 4: conduct user research to inform system development user research will be essential to informing the design and functionality of the xc software. to align xc’s functional requirements as closely as possible with user needs, the xc project team will practice a user-centered design methodology that takes an iterative approach to defining the system’s functional requirements. since we will engage concurrently in the processes of user research and software design, we will not fully determine the system requirements for xc until a significant amount of user research has been done. a complete picture of the demands upon metadata within xc will thus emerge as we gain information from our user research. n goal 5: publish the xc code as open-source software central to the vision of the xc project is sharing the xc software freely throughout the library community and beyond. our hope is that others will use all or part of the xc software, modify it, and improve it to meet their own needs. new requirements for the metadata within xc are likely to arise as this process takes place. other future changes to the xc software will also be needed to ensure the software’s continued compatibility with various metadata standards and schemas. these changes will all affect the system requirements for xc over time. addressing goals 4 and 5 while goals 1 through 3 for the xc project result in specific high-level functional requirements for the system’s discovery metadata that can be addressed and discussed as xc is being developed, goals 4 and 5 present general challenges that must be addressed in the future. goal 4 is likely to fuel the need to update the xc software over time as the needs of users change. goal 5 provides a challenge to managing that updating process in a collaborative environment. these two goals suggest an additional general requirement for the system’s metadata requirement 7: requirement 7—the system’s metadata must be extensible to facilitate future enhancements and updates. enabling future user needs developing xc using a user-centered design process in which user research and software design occur simultaneously will enable us to design and build a system that is as responsive as possible to the needs of users that are seeking library resources. however, user needs will change during the life of the xc software. these needs must be assessed and addressed, and then weighed against the desires of individual institutions that use xc and who request specific system enhancements. to carry forward the xc project’s commitment to serving users, we will develop a governance model for the xc community that brings the needs of future users into the decision-making process by providing a method for continuing to determine and capture user needs. in addition, we will consciously cultivate a commitment to user research among members of the xc community. because the xc software will be released as open source, we can also encourage xc partners to develop whatever additional functionality they need for their own institutions and make these enhancements available to the entire community of xc users. this approach is very different from the enhancement process in place for most commercial systems, and xc partner institutions may need to adjust to this approach. enabling future metadata standards as current metadata standards are revised and new standards and schemas are created, xc must be able to accommodate these changes. new crosswalks will allow new metadata schemas to be mapped to the xc internal schema in the future. the xc application profile can be updated with the addition of new data elements as needed. the drupal-based xc user environment will also allow institutions that use xc to create new internal data types to incorporate additional types of metadata. as the development of the semantic web moves forward73 and enables smart linking between existing authority files and vocabularies,74 xc’s architecture can make use of the resulting web services, either by incorporating them metadata to support next-generation library resource discovery | bowen 15 through the xc metadata services hub or through the native xc user interface as part of a user search query. n further considerations the above discussion of the goals and requirements for xc has revealed a number of issues related to the development of next-generation discovery systems that are unfortunately beyond the scope of the next phase of the xc project. we therefore offer them as a possible agenda for future work by the broader library community: 1. explore the wider usefulness of web-based metadata services and the need for an automated metadata services coordinator to control these functions. libraries are already comfortable with basic “services” that are performed on metadata by an outside agency: for example, a library may send copies of its marc records to a vendor for authority processing or enrichment with tables of contents or other data elements. the library community should encourage vendors and others to develop these and other metadata enrichment options as automated web services. 2. study the advantages of using statement-level metadata provenance, as used in the nsdl metadata management system and considered for use within the xc metadata services hub, and explore whether there are ways that marc 21 could move toward allowing more granularity in recording and sharing metadata provenance. 3. to facilitate access to licensed library resources, encourage the development of more robust metasearch technology and standards so that technological limitations do not hinder system performance and search result usability. if this is not successful, libraries and content providers must work together to enable metadata for licensed resources to be revealed within open discovery environments such as xc and ethicshare.75 this second scenario will enable libraries to directly address usability issues with the display of licensed content, which may make it a more desirable longer-term solution than attempting to improve metasearch technology. 4. the administrative bodies of the two groups represented on the dcmi/rda task group (i.e., the dublin core metadata initiative and the rda committee of principals) have a responsibility to take the lead in funding this group’s work to develop and maintain the rda/dc application profile and its related registries and vocabularies. beyond this, however, the broader library community must recognize that this work is essential to ensure that future library metadata standards will function in the broader web environment, and offer additional administrative and financial support for it in the coming years. 5. to ensure that library standards work effectively outside of traditional library systems, catalogers and metadata experts must develop ongoing, collaborative working relationships with system developers. such collaboration will necessitate educating each group of experts about the domain of the other. 6. libraries should experiment with using metadata in new environments and use the lessons learned from this activity to inform the metadata standards development process. while current library automation environments by and large do not provide opportunities for this, the extensible catalog will provide a flexible platform where experimentation can take place.76 xc will make experimentation as risk-free as possible by ensuring that the original metadata brought into the system can be reharvested in its original form, thus minimizing concerns about possible data corruption. xc will also minimize the investment needed for a library to engage in this experimentation because it will be released as open-source software. 7. to facilitate new functionality for next-generation library discovery environments, libraries must share their new expertise in this area with each other. for example, library professional organizations (such as ala and its associations) should form discussion groups and committees devoted to sharing lessons learned from the implementation of faceted interfaces and web 2.0 technologies, such as tagging and folksonomies. such groups should develop a “best practices” document outlining a preferred way to define facets from marc 21 data that can be used by any library implementing faceting on top of its legacy metadata. 8. the library community should discuss and encourage mechanisms for pooling and sharing usergenerated metadata among libraries and other interested institutions. n conclusions to present library resources via the web in a manner that users now expect, library metadata must function in ways that have never been required of it before. making library metadata function effectively within the broader web environment will require that libraries take advantage of the combined knowledge of experts in the areas of cataloging/metadata and system development who share a 16 information technology and libraries | june 2008 common vision for serving library users. the challenges to making legacy library metadata and newer metadata for digital resources interact effectively in the broader web environment are significant, and work must begin now to ensure that we can preserve the investment that libraries have made in their legacy metadata. while the recommendations within this report are the result of planning to develop one particular library discovery system—the extensible catalog (xc)—these lessons can inform the development of other systems as well. the actual development of xc will continue to add to our knowledge in this area. while it may be tempting to wait and see what commercial vendors offer as their next generation of commercial discovery products, such a passive approach may jeopardize the future viability of library metadata. projects such as the extensible catalog can serve as a vehicle for moving forward by providing an opportunity for libraries to experiment and to then take informed action to move the library community toward a next generation of resource discovery systems.

usability as a method for assessing discovery | ipri, yunkin, and brown 181 tom ipri, michael yunkin, and jeanne m. brown usability as a method for assessing discovery the university of nevada las vegas libraries engaged in three projects that helped identify areas of its website that had inhibited discovery of services and resources. these projects also helped generate staff interest in the usability working group, which led these endeavors. the first project studied student responses to the site. the second focused on a usability test with the libraries’ peer research coaches and resulted in a presentation of those findings to the libraries staff. the final project involved a specialized test, the results of which also were presented to staff. all three of these projects led to improvements to the website and will inform a larger redesign. u sability testing has been a component of the university of nevada las vegas (unlv) libraries web management since our first usability studies in 2000.1 usability studies are a widely used and relatively standard set of tools for gaining insight into web functionality. these tests can explore issues such as the effectiveness of interactive forms or the complexity of accessing full-text articles from third-party databases. they can explore aesthetic and other emotional responses to a site. in addition, they can provide an opportunity to collect input concerning satisfaction with the layout and logic of the site. they can reveal mistakes on the site, such as coding errors, incorrect or broken links, and problematic wording. they also allow us to engage in testing issues of discovery to isolate site elements that facilitate or hamper discovery of the libraries’ resources and services. the libraries’ usability working group seized upon two library-wide opportunities to highlight findings of the past year’s studies. the first was the discovery summit, in which the staff viewed videos of staff attempting finding exercises on the homepage and discussed the finding process. the second was the discovery mini-conference, an outgrowth of a new evaluation framework and the libraries’ strategic plan. through a poster display, the working group highlighted areas dealing with discovery of library resources. the mini-conference allowed us to leverage library-wide interest in the topic of effective information-finding on the web to draw wider attention to usability’s importance in identifying the likelihood of our users discovering library resources independently. the usability working group engaged in three projects to help identify areas of the website that inhibited discovery and to generate staff interest in the process of usability. all three of these projects led to improvements to the website and will inform a larger redesign. the first project is an ongoing effort to study student responses to the site. the second was to administer a usability test with the libraries’ peer research coaches and present those findings to the libraries’ staff. the final project was requested by the dean of libraries and involved a specialized test, the results of which also were presented to staff. n student studies the usability working group began its ongoing evaluation of unlv libraries’ website by conducting two series of tests: one with five undergraduate students and one with five graduate students. not surprisingly, most students self-reported that the main reason they come to the libraries’ site is to find books and journal articles for assignments. the group created a set of fourteen tasks that were based on common needs for completing assignments: 1. find a journal article on the death penalty. (note: if students go somewhere other than the library, guide them back.) 2. find what floor the book the catcher in the rye is on. 3. find the most current issue of the journal popular mechanics. 4. identify a way to ask a question from home. 5. find a video on global warming. 6. you need to write a bibliography for a paper. find something on the website that would help you. 7. find out what lied library’s hours were for july 4. 8. find the libraries’ tutorial on finding books in the library. 9. the library offers workshops on how to use the library. find one you can take. 10. find a library-recommended website in business. 11. find out what books are checked out on this card. 12. find instructions for printing from your personal laptop. 13. your sociology professor, dr. lampert, has placed something on reserve for your class. please find the material. 14. your professor wants you to read the book efficiency and complexity in grammars by john a. hawkins. find a copy of the book for your assignment.

will prompt if the person stops at the catalog.) the results of these tests revealed that the site was not as conducive to discovery as was hoped. the libraries are planning on a complete redesign of the site in the near future; however, the results of these first two series of usability tests were compelling enough to prompt an intermediary redesign to improve some of the areas that were troublesome to students. that said, the tests also found certain parts of the old site (figure 1) to be very effective: 1. all participants used the tabbed box in the center of the page, which gives them access to the catalog, serials lists, databases, and reserves. 2. all students quickly found the “ask a librarian” link when prompted to find a way to ask a question from home. 3. most students found the libraries’ hours, partly because of the “hours” tab at the top of the page and partly because of multiple access points. 4. many participants used the “site search” tab to navigate to the search page, but few actually used it to conduct searches. they effectively used the site map information also included on the search page. the usability tests also revealed some variables that undermined the goal of discoverability. 1. due to the various sources of library-related information (website, catalog, vendor databases) navigation posed problems for students. although not a specific question in the usability tests, the results show students often struggled to get back to the libraries’ home page to start a new question. 2. students often expected to find different content under “help and instruction” than what was there. 3. students used the drop down boxes as a last resort. often, they would expand a drop down box and quickly navigate away without selecting anything from the list. 4. with some exceptions, students mainly ignored the tabs across the top of the home page. 5. although students made good use of the tabbed box in the center of the page, many could not distinguish between “journals” and “articles & databases.” 6. similarly, students easily found the “reserves” tab but could not make sense of the difference between “electronic reserves (e-reserves)” and “other reserves.” 7. no student found business resources via the “subject guides” drop down menu at the bottom of the home page. n peer-coach test and staff presentation unlv libraries employs peer research coaches, undergraduate students who serve as frontline research mentors to their peers. the usability working group administered the same test they used with the first group of undergraduate and graduate students to the peer research coaches. although these students are trained in library research, they still struggled with some of the usability tasks. the usability working group presented the findings of the peer research coach tests with staff. the peer research coaches are highly regarded in the libraries, so staff were surprised that they had so much difficulty navigating the site; this presentation was the first time many of the staff had seen the results of usability studies of the site. the shocking nature of these results generated a great deal of interest among the staff regarding the work of the usability working group. n the dean’s project in january 2009, the dean of libraries asked the usability working group for assistance in planning for the discovery summit. initially, she requested to view figure 1. unlv libraries’ original website design usability as a method for assessing discovery | ipri, yunkin, and brown 183 the video from some of the usability tests with the goal of identifying discovery-oriented problems on the libraries’ website. soon after, the dean tasked the group with performing a new set of usability tests using three subjects: a librarian, a library employee with little research or web expertise, and a faculty researcher. each participant was asked to complete three tasks, first using the libraries’ website, then using google. the tasks were based on items found in the libraries’ special collections: 1. find a photograph available in unlv libraries of the basic magnesium mine in henderson, nevada. 2. find some information about the baneberry nuclear test. are there any documents in unlv libraries about the lawsuit associated with the test? 3. find some information about the local greenpeace chapter. are there any documents in unlv libraries about the las vegas chapter? the dean viewed those videos and chose the most interesting clips for a presentation at the discovery summit. prior to this meeting, the libraries’ staff were instructed to try completing the tasks on their own so that they might see the potential difficulties users must overcome and to compare the user experience provided by our website with that provided by google. at the discovery summit, the dean presented the staff a number of clips from these special usability tests, giving the staff an opportunity to see where users familiar with the libraries collections stumble. the staff also were shown several clips of undergraduates using the website to perform basic tasks, such as finding journal articles or videos in the libraries, with varying degrees of success. these clips helped illustrate the various difficulties users encounter when attempting to discover library holdings, including unfamiliar search interfaces, library jargon, and a lack of clear relationships between the catalog and other databases. this discussion helped set the stage for the discovery mini-conference. n initial changes to the site unlv libraries’ website is in the process of being redesigned, and the results of the usability studies are being used to inform that process. however, because of the seriousness of some of the issues, some changes are being implemented into an intermediary design (figure 2). the new homepage n combines article and journal searching into one tab and removes the word “databases” from the page entirely; n adds a website search to the tabbed box; n adds a “music & video” search option; n makes better use of the picture on the page by incorporating rotating advertisements in that area; n widens the page, allowing more space on the rest of the site’s templates; n breaks the confusing “help & instruction” page into two more specific pages: “help” and “using the libraries”; and n adds the main library and the branch library hours to the homepage. this new homepage is just the beginning of our efforts to improve discovery through the libraries’ website. the usability working group already has plans to do a card sort for the “using the library” category to further refine the content and language of that section. the group plans to test the initial changes to the site to ensure that they are improving discovery. reference 1. jennifer church, jeanne brown, and diane vanderpol, “walking the web: usability testing of navigational pathways

libraries and cultural resources (lcr) at the university of calgary used qualtrics xm to design and pilot a point-of-use survey to collect user feedback on the usability of our implementation of primo, ex libris's web-scale discovery service. over a two-week period, users were presented with the pop-up survey while searching and asked to provide feedback. this article summarizes how we designed and implemented this point-of-use survey and the lessons learned from this project. introduction in 2018, libraries and cultural resources (lcr) at the university of calgary implemented ex libris’s primo, a web-scale discovery service.1 through an embedded search box on the library webpage (https://www.library.ucaglary.ca), users can use primo to discover and access resources from lcr’s physical and digital collections. after adopting primo, lcr wanted to assess usability of the interface and the initial decisions made around user interface display customizations. to do this, in early 2020 lcr’s primo working group piloted a point-of-use intercept survey using qualtrics xm to collect feedback from users on the success of their search experience. for this, we defined success as users’ perception that they found what they were looking for. as we were unable to find comprehensive guidance on how to set up such a survey, this article will share our process and lessons learned in the hope that others will find it useful. primo and usability ex libris designed primo “to catch up with user expectations” through implementing “contemporary user experience elements.”2 since the initial release, many academic libraries have conducted user experience studies on primo that involved recruiting users and asking them to complete specific common tasks while under observation. study designers then analyze the results for insights into user experience.3 these studies capture feedback from a sample of users in the context of a usability test environment, which is to some extent artificial. in our study, we aimed to capture authentic user feedback as they searched using primo, not as they completed predetermined tasks. in the marketing profession, this is known as an intercept survey, an online survey that is triggered during the use of a site or application and can be used to study “natural use of the product.”4 in the library context, martha kyrillidou, terry plum, and bruce thompson used this method, which they referred to as point-of-use surveys, to collect user feedback on networked electronic resources. importantly, they contended that point-of-use surveys can improve the validity and mailto:mblack@ucalgary.ca mailto:hganshor@ucalgary.ca mailto:jwheeler@ucalgary.ca https://www.library.ucaglary.ca/ information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 2 black, ganshorn, and wheeler response rates of a survey because the survey does not require users to report on “predicted, intended, or remembered use” (which can introduce error) and that proactive interception increases the number of responses and decreases the potential for bias due to nonresponse rates.5 further, jane nichols, richard stoddart, and terry reese explained how oregon state university libraries and press designed and implemented an in-house intercept survey for collection assessment and noted the in-house method required significant time and support from their developers and that they would investigate whether qualtrics could support the intercept functionality.6 using qualtrics xm to deliver a survey in early 2020, lcr formed a primo working group, which includes representative from library systems, research and learning services, public services, and collections. the group meets monthly to review primo developments and work on improving our search experience. after our initial meetings, the group began to discuss how we collect user feedback on our discovery search interface. a subgroup was formed to come up with a strategy for this assessment. in the subgroup’s initial meeting, we decided to collect user feedback on search experience by asking open-ended questions about how successful users perceived they were with their search and to ask them to identify the elements of the interface that helped or hinder their success. for this, we decided to use qualtrics xm because it is the university of calgary’s licensed survey tool and we determined it could be used to deliver the survey as a pop-up. using qualtrics xm, we first developed a test survey to understand how to set up the survey flow and how to create the pop-up to display to users. after setting this up, we shared a test version with the primo working group for feedback on the design and testing in our primo sandbox. based on this feedback, we finalized a short survey that asked users if they found the resources they were looking for and included a follow-up question about why they feel their search was successful or unsuccessful (see fig. 1). the questions were: 1. what user group do you belong to? if you belong to more than one group, choose the group that had brought you to the library today: • academic staff • support staff and management & professional staff • undergraduate student • graduate student • continuing education student • community user • other 2. did you find what you needed? • yes (conditionally linked to question 3a) • no (conditionally linked to question 3b) • somewhat (conditionally linked to question 3a and 3b) 3. • 3a. what helped you find what you needed? • 3b. why do you think your search was not successful? information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 3 black, ganshorn, and wheeler figure 1. finalized survey questions and design in qualtrics xm. after finalizing the survey, we configured the pop-up. our plan was to run the survey for a twoweek period. during this two-week window when the survey was active, users would be presented with a pop-up during their primo search session asking if they would like to provide feedback. to trigger the display of the survey in a pop-up, we used qualtrics xm’s built-in functionality to create a point-of-use intercept, a website & app feedback project (see fig. 2). figure 2. create a website & app feedback project screen. after creating the project, we needed to configure the intercept and creative. the intercept is used to define the conditions for when a user on a site or app is presented with the survey. the creative is the method for delivering the survey to the users once intercepted on the site. for this project, we decided to use the responsive dialog creative to connect users to our survey (see fig. 3). information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 4 black, ganshorn, and wheeler figure 3. feedback collection method selection screen. within the creative, we were able to configure and preview the size, style, and text for the dialog and buttons; add images, such as a logo; and set the display animation (see fig. 4). figure 4. responsive dialog creative configuration screen. we configured the dialog to allow users to accept or decline our request to take the survey and branded it with our logo and colors (see fig. 5). information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 5 black, ganshorn, and wheeler figure 5. responsive dialog creative with customized message, buttons, colors, and logo. once we configured the creative, we needed to set up the intercept. we set the survey as the target for the intercept and defined the targeting logic and frequency. for the targeting logic, we used the “if current url starts with” option and used the base url for our primo instance (see fig. 6). figure 6. intercept targeting logic configuration. for the frequency, we configured it to intercept users only when their mouse left the web page because we did not want the survey to intercept users before they had tried searching. this was our best approximation for ensuring the intercept timing was appropriate for the questions we were asking. we determined the other available options would display the survey too early (on load or on focus) and not have achieved a valid timing for the questions. there is also an option to use custom javascript code to set the timing, but we decided to just use the out-of-the-box options because we wanted to keep the configuration simple (see fig. 7). information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 6 black, ganshorn, and wheeler figure 7. intercept frequency configuration. to avoid frustrating users by displaying the survey too frequently, we used the “repeated display prevention for browser cookie” option. within this configuration, we set the survey to display to 100% of the users who qualify but prevented repeated display for one day. this meant users would not be asked to take the survey more than once a day. to add the intercept to primo, we copied the javascript code snippet that qualtrics xm generates and added this to the custom.js file in our primo customization package (see fig. 8). figure 8. javascript code snippet for the responsive dialog. once this code is deployed in primo, the intercept behavior can be controlled within qualtrics xm by simply activating or deactivating it within the website/app feedback project (see fig 9). figure 9. configuration page with the activation toggle highlighted. information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 7 black, ganshorn, and wheeler this was convenient because we could leave the code in the primo custom.js file and deactivate or activate in qualtrics xm as necessary. in addition, when we later updated the target of the intercept to an updated version of the survey we did not have to update the code in primo. lessons learned proactively intercepting users at point of use can result in a significant number of responses over a short period of time. as mentioned above, we initially ran the survey with the intercept for a two-week period and again, for the same period of time, during two additional semesters. between these periods, we left the survey active as a passive sidebar that users could choose to access. this passive method collected fewer responses (107) over a six-month period than the point-of-use survey (755) collected over the combined six weeks that the pop-up prompt was active. for those who are interested in running a point-of-use survey, we summarize the lessons we learned below. when designing a survey consider the following • keep the survey short and focused on a specific goal. • assess the survey questions after piloting and iterate—adjust or clarify questions if needed. when designing the point-of-use intercept consider the following • make sure the point-of-use intercept will not frustrate users by controlling how frequently the survey is presented. • make sure the timing of the pop-up dialog aligns with your goal(s) by considering: o when do your primary stakeholders most heavily use library resources? o what is the minimum number of responses you aim to collect? o how long do you need to run the survey to achieve this number? o at what point in the users’ search will the survey intercept users to ask for feedback? will this timing be at the point of use you want feedback on? provide users with options for timely support we found that users sometimes confused the feedback survey with an opportunity to report issues or ask for help. accordingly, at the end of the survey we added a closing message that provided users with options to get immediate help using chat or our faqs (see fig. 10). figure 10. survey closing message. information technology and libraries december 2023 using qualtrics xm to create a “point-of-use” survey 8 black, ganshorn, and wheeler conclusion for academic libraries with access via an institutional license, qualtrics xm is a flexible and relatively simple tool that can be used to gather point-of-use feedback on user experiences with library discovery services such as primo. in our case, we analyzed the results for themes and shared these with our primo working group. as a result, the group reviewed the results and came up with actionable items such as updating our display labels for facets, resource availability statements, and access and licensing. this method may also be applicable for collecting feedback on other elements of a library website, vendor platforms, or online collections. endnotes

roleplaying narratives and length in instructional video amanda s. clossen information technology and libraries | march 2018 27 amanda s. clossen (asc17@psu.edu) is learning design librarian, pennsylvania state university. abstract a concern that librarians face when creating video is whether users will actually watch the video they are directed to. this is a significant issue when it comes to how-to and other point-of-need videos. how should a video be designed to ensure maximum student interest and engagement? many of the basic skills demonstrated in how-to videos are crucial for success in research but are not always directly connected to a class. whether a video is selected for inclusion by an instructor or viewed after it is noticed by a student depends on how viewable the video is perceived to be. this article will discuss the results of a survey of more than thirteen hundred respondents. this survey was designed to establish the broad preferences of the viewers of instructional how-to videos, specifically focusing on the question of whether the length and presence of a role-playing narrative enhances or detracts from the viewer experience, depending on demographic. literature review length since the seminal 2010 study by bowles-terry, hensley, and hinchliffe established emerging best practices for pace, length, content, look and feel, and video versus text, a variety of works compiling best practices for video have been created.1 the very successful library minute videos from arizona state university resulted in a collection of how-tos and best practices by rachel perry.2 these included tips on addressing an audience, planning, content, length, frugality, and experimentation. in 2014 coastal carolina nursing students were surveyed for their preferences in video, resulting in another set of best practices. these focused on video length, speaking pace, zoom functionality, and use of callouts.3 martin and martin’s extensive 2015 review covers content, compatibility, accessibility, and audio.4 the recommended length listed in these best practices varies widely. thirty-seconds to a minute is recommended by bowles-terry, hensley, and hinchliffe, while perry recommends no longer than ninety seconds.5 the coastal carolina study and seminole state review recommend no longer than three minutes.6 nearly all the articles reviewed stress that complicated concepts should be broken into more easily comprehensible chunks to avoid overwhelming student cognitive load. mailto:asc17@psu.edu trope or trap? role-playing narratives and length in instructional video | clossen 28 https://doi.org/10.6017/ital.v37i1.10046 narrative roleplay scenario the typical roleplay involves a hypothetical student who needs some sort of assistance and is helped through the process using library resources. often there is also a hypothetical guide, who can be a librarian, friend, or professor. these hypothetical situations are recorded in a variety of ways: from live-action video recordings, to screencast voice-overs, to text. the efficacy of such tools in library video have been explored little, if at all. devine, quinn, and aguilar’s 2014 study explores the usage and effectiveness of microand macro-narratives in resident information literacy instruction,7 but there is no question that this instructional scenario is very different than how-to instructional videos. the interplay between student interest and such narratives is addressed by emotional interest theory, which states that adding unrelated but interesting material increases attention by energizing the learner. these unrelated pieces of engaging material are known as seductive details. this “highly interesting and entertaining information . . . is only tangentially related to the topic but is irrelevant to the author’s intended theme.”8 exploration of this concept through experimental study has indicated that seductive details are detrimental to learning.9 some evidence indicates that learners are more likely to remember these details than the important content itself thanks to cognitive load issues.10 however, there have also been cases where seductive details have improved recall.11 in their 2015 study, park, flowerday, and brünken argue that the format and presentation of seductive details have varying effect on learning processes and that they can be used to positive effect.12 in this paper, the seductive details to be studied are those of the roleplay narrative used to frame instruction in how-to videos. methods survey design the survey was designed to explore three questions: • does the length of the video affect a user’s willingness to watch it? • do users prefer videos that are pure instruction or those that use a roleplay narrative to deliver content? • does the demographic of the viewer affect a video’s viewability? the survey was revised in collaboration with a survey design and statistical specialist at the penn state library’s data learning center. the completed survey was then entered into qualtrics for implementation. implementation implementation and subject-gathering was done through a survey-research sampling company that provided both a wide demographic and rapid data collection. this was sponsored by an institutional grant. subjects from a variety of institution types and geographic locations were solicited via email invitation to complete a survey that explored their perspectives on instructional videos. information technology and libraries | march 2018 29 the twenty-question survey was focused on respondents of a traditional college age. implementation resulted in 1,305 responses out of 1,528 surveys. after implementation, results were compiled and analyzed by a statistical expert at the institutional data center. nearly all the analyses to follow are simple cross-tabulations of respondent choices as correlations between demographics and preference were minor based on a multivariate analysis of variance (manova) test. results and discussion demographics the survey, which was limited to a traditionally college-aged population (eighteen to twentyfour), produced a nearly 1:1 gender distribution (figure 1). figure 1. age and gender distribution. the survey had around 64 percent student participants, 77 percent of these attending school full time. of those full-time students, 60 percent were resident students, and only 9 percent were solely online students. unemployed participants were more likely to be full-time resident students whereas online students were more likely to be employed full-time.

(see figure 6.) figure 6. screencast reactions. when asked an open-ended question about what struck them the most in the screencast video, respondents most frequently stated that they found it to be informative and interesting, or at least neutral. however, a variety of responses were observed, both negative and positive, or even contradictory. it is worth noting that within this open-ended format, dislike of the narrator’s voice was independently assigned as one of the top three issues. this stresses the importance of coherent and pleasant narration, as it is something that viewers will likely notice. trope or trap? role-playing narratives and length in instructional video | clossen 34 https://doi.org/10.6017/ital.v37i1.10046 figure 7. open-ended questions: screencast. narrative while watching the narrative video, participants found that they could relate to the characters or scenario and found that they were learning as much as they were when watching the screencast (see figure 8). however, there were mixed responses regarding video length and credibility of the narrator. when compared across demographics, employed respondents and students were more likely to agree that they could relate to the scenario than unemployed and nonstudents. male respondents and employed were more likely to think that the video went too fast than female and unemployed respondents. when asked an open-ended question on what most struck them about the narrative video, respondents most often stated that they found it to be boring and long, though a good number also indicated it was interesting and informative (see figure 9). just as with the screencast video, a variety of responses, both negative and positive, were observed, some even conflicting. information technology and

https://doi.org/10.6017/ital.v37i1.10046 in addition, 13.5 percent of respondents were unsatisfied with the content of the video. just as with the screencast video, a variety of responses, both negative and positive, were observed, some even conflicting. screencast versus narrative the screencast video tended to be preferred by respondents, with higher average scores in content, engagement, learning value, and narrator trustworthiness. in contrast, respondents also thought that the screencast video moved too quickly compared to the narrative video. additionally, participants were more impatient during the narrative video (see figure 10). figure 10. screencast versus narrative. to observe differences between the screencast and narrative videos with regards to respondent reactions within specific population demographics, manova test was performed. this test revealed that none of the p-values were significant (at α = .05), leaving no correlation between student status, employment status, and reaction to each video. a more liberal interpretation of the data from this analysis might conclude that differences in impatience across student status were possibly significant (α = .10), with students being more likely to exhibit a smaller difference in *score defined as 1 = “not very much” to 5 = “very much”, with difference = screencast score – narrative score. red rows indicate higher scores for the narrative video. statistics for differences in screencast and narrative* (n=1305) information technology and libraries | march 2018 37 impatience for the two video styles. the preferences for screencast over narrative video did not change when the demographics were spliced. conclusions it is impossible to please everyone all the time—at least that is what survey results suggest. there are several takeaways to this study: video length matters, especially as a consideration before the video is viewed. timestamps should be included in video creation, or it is highly likely that the video will not be viewed. the video player is key here, as some video players include video length, while others do not. videos that exceed four minutes are unlikely to be viewed unless they are required. voice quality in narration matters. although preference in type of voice inevitably varies, the actor’s voice is noticed over production value. it is important that the narrator speaks evenly and clearly. for brief how-to videos, there is a small preference for screencast instructional videos over a narrative roleplay scenario. the results of the survey indicate that roleplay videos should be wellproduced, brief, and high quality. however, what constitutes high quality is not very well established.15 finally, screencast videos should include an example scenario, however brief, to ground the viewer in the task. suggestions for further study next steps for research might include a more refined survey focusing on the results of this study. of equal value would be a series of focus groups that are given both a screencast and narrative video and asked to discuss their preferences. though a wide variety of students were surveyed, limits of this dataset prevented the exploration of specific correlations among students attending different institution types or among those pursing different majors. further research addressing the differences among these student bodies would be a welcome addition to the literature. references 1 melissa bowles-terry, merinda kaye hensley, and lisa janicke hinchliffe, “best practices for online video

references salazar 170 information technology and libraries | september 2006 author id box for 3 column layout traditional, larger libraries can rely on their physical collection, coffee shops, and study rooms as ways to entice patrons into their library. yet virtual libraries merely have their online presence to attract students to resources. this can only be achieved by providing a fully functional site that is well designed and organized, allowing patrons to navigate and locate information easily. one such technology significantly improving the overall usefulness of web sites is a content management system (cms). although the cms is not a novel technology per se, it is a technology smaller libraries cannot afford to ignore. in the fall of 2004, the northcentral university electronic learning resources center (elrc), a small, virtual library, moved from a static to a database-driven web site. this article explains the importance of a cms for the virtual or smaller library and describes the methodology used by elrc to complete the project. state of the virtual library the northcentral university electronic learning resource center (elrc), a virtual library, recently moved from a static to a databasedriven web site in 2004.1 before this, the site consisted of 450 static pages and continued to multiply due to the creation and expansion of northcentral university (ncu) programs. to provide the type of service demanded by our internet-savvy patrons, the elrc felt it needed to evolve to the next stage of web management and design. ncu, with a current enrollment of roughly twenty-one hundred fulltime students, is one of many forprofit virtual universities (including the university of phoenix, capella, and walden, among others) seeking to carve a niche in the education market by offering professional degrees entirely online.2 in the past few years, distance education has experienced exponential growth, causing virtual universities to flourish, but forcing on their libraries the challenge of keeping pace.3 typically, virtual libraries are manned by a limited staff comprised of one or two librarians who are responsible for all facets of the library, including interlibrary loan, virtual reference, library instruction, and web site management, among other library duties. 4 web site management, as expected, becomes cumbersome when a site exceeds two hundred or more static pages and a clear and structured system is not in place to maintain a proliferating number of web pages. because virtual, for-profit libraries do not rely on public funding and taxes, they tend not to be as concerned about autonomy as public or state libraries, which must find ways to stay within budget and curtail expenses. on the same note, some academic libraries prefer to maintain a local area network (lan), while other libraries may not have the staff, resources, or need for such a system. thus, for some virtual libraries, such as elrc, the incorporation of technology takes on a more dependent role. that is, where some libraries are encouraged to explore open source applications and create homegrown tools, the virtual, smaller-staffed library finds itself more or less reliant on its university’s information technology (it) department.5 virtual libraries address the needs of distance education students, who demand an equivalent, if not surpassing, level of service and instruction as they would expect to find at physical libraries.6 meeting these needs requires a great deal of creativity, ingenuity, and a strong technical background. recent trends in developing technologies such as mylibrary, learning objects, blogs, virtual chat, and federated searching have broadened the scope of possibilities for the smaller-staffed, virtual library. in particular, a content management system (cms) utilizes a combination of tools that provide numerous advantages, as outlined below: 1. the creation of templates that maintain a consistent design throughout the site 2. the convenience of adding, updating, and deleting information from a single, online location 3. the creation and maintenance of interactive pages or learning objects 4. the implementation of a simple editing interface that eliminates knowledge of extensible hypertext markup language/hypertext markup language (xhtml/ html) by library staff simply defined, a cms is comprised of a database, server pages such as active server page (asp), personal home page (php), or coldfusion; a web server—for example, internet information server (iis), personal web server (pws), or apache; and an editing tool to manage web content.7 these resources vary in price, but for a virtual library integrated into a larger university, it is ideal to implement applications and software supported by the university. for the autonomous academic library, this may differ. there are advantages and disadvantages for using proprietary and nonproprietary software, and it is left to the library, virtual or physical, to determine the type of resources needed to meet the goals and mission of the university.8 although the scope of this article focuses on the creation of tools for a homegrown cms, some libraries may wish to explore commercial cms packages that include additional services such as technical support. these cms packages will vary in price and services depending on the vendor and the needs of the library.9 elrc transformed in fall 2004, a group that consisted ed salazar (esalazar@ncu.edu) is reference/web librarian at northcentral university. content management for the virtual library ed salazar article title | author 171content management for the virtual library | salazar 171 of two librarians, the education chair, and programmer, convened to discuss the redesign of the elrc web site, which had become increasingly difficult to manage. specifically, the amount of duplicated content, inconsistent design and layout, and unstructured architecture of the site posed severe navigational and organizational problems. the group selected and compared other academic library sites to determine a desired design and theme for the new elrc site. discussions also involved the addition of features such as a site search and breadcrumbs, which the group felt were essential. as a result, the creation of a homegrown cms using proprietary software became the route of choice to meeting the increasing demands of patrons and the need to expand the site. because ncu utilizes microsoft (ms) information system products, it was agreed ms or ms-compatible applications would be used to create the cms, which consisted of sql server, iis, asp, visual basic script (vbscript), jspell iframe, and ms visual interdev. ms visual interdev and jspell iframe supplanted our previous web editor, ms frontpage, which seemed to generate superfluous code and thus made it difficult to debug or alter the design and layout of pages. also, using jspell iframe eliminated the need for future ncu librarians to possess an expertise in xhtml/html. with these pieces in place, the arduous task of culling content from static pages and entering it into a database was begun. the database the sql server database helped in organizing and structuring content, and allowed for the creation of templates and administration (admin) pages.10 in addition, the database played an integral part in creating the search, breadcrumb, and site map features the group so desperately wanted. a significant amount of time was spent weeding the site for information that had become obsolete or irrelevant to elrc. it should be noted that the group originally attempted to use access for a database but stumbled across several problems, one being the inability to maintain a stable and reliable connection to the database. the templates with the database nearly complete, the programmer began creating asp templates in ms visual interdev. these templates basically serve as the shell of the web page, preserving the design and layout elements of the page while extracting unique content based on a user’s request. in essence, a single template can produce hundreds of pages consistent in design. likewise, a single change to the template can alter the entire design of the site. for the elrc, seven templates were created for more than 450 pages. figure 1 shows the elrc course guides template. figure 2 shows the public view of the elrc course guide template. changes to the templates are done using ms visual interdev, which offers a user-friendly environment for managing web pages. ms visual interdev also includes helpful features, such as highlighting code errors for easy debugging, and the ability to access, create, and maintain stable connections to databases.11 in addition, the ms visual interdev editor recognizes commonly used asp commands, allowing the user to save time by utilizing keyboard shortcuts when programming. besides creating templates, asp server-include files and cascading style sheets (css) were incorporated, allowing for the easy modification of code on a single file instead of each and every page or template. this, in particular, is time-efficient when having to add or change database connections or design elements. also, the elrc took extra precaution to ensure that style elements met the accessibility requirements and standards set forth by the world wide web consortium (w3c), as well as tested the site on other browsers, such as firefox and netscape.12 as the site continues to grow and expand, so may the need for additional templates. creation or replication of templates is simple, requiring a basic understanding of programming and the re-assigning of new variables in the code to match added or modified tables. there is some speculation in the near future of migrating the site to the asp.net environment for added functionality and security. if and when that time comes, the elrc will be ready. at present, ncu is not considering the use of open source code or applications (the exception being the apache web server); this is primarily due to available technical support, security, and intuitiveness of use associated with commercial software. in addition, the ncu information system was built using commercial software and a complete transition to open source, at the moment, is not possible or desirable. with the templates complete, the elrc began running a prototype of the new site, making it accessible to students and faculty from a link on the old site. a survey was created that allowed users to comment on the new site. one detail of importance to note is that the survey duplicated a prior survey done on the old site in 2003 in order to provide the elrc with comparative data. the admin pages the next phase of the project required the creation of admin pages, which would allow content to be quickly added, updated, and deleted on the site. these pages, like the templates, were created in ms visual interdev; display content is housed within the database on the web, thus allowing 172 information technology and libraries | september 2006 it to be changed on the fly. figure 3 shows all of the web pages for the elrc within a table. what is particularly convenient about the admin edit pages is the incorporation of the jspell iframe editor, which serves as the frontend editor to the site. the reason for using jspell iframe, as stated earlier, is its ease of use: the simple tool bar provides the basic, essential tools necessary for creating content without the daunting number of buttons and menu selections other editors tend to have. also, jspell iframe is reasonably priced and does not entail a complex installation or require any space on local hard drives; instead, the program is maintained on the server. consequentially, all that is required is the insertion of the jspell iframe javascript code into the web pages. in addition to jspell iframe, fields within admin edit pages are or can be pre-populated by content in the database. for instance, the title or display order of links can be easily edited or changed. longer text fields comprised of paragraphs are created or modified using jspell iframe. deleting a page is simple, requiring only the click of a delete button on the bottom, righthand corner. figure 4 shows jspell iframe embedded within an admin edit page. the admin add page is straightforward. information is entered into the fields appearing on a form page, and the proper page type designation is selected from a drop-down menu. yet, more importantly, the admin add and the admin edit pages can filter information to specific users for security purposes and library needs. figure 5 shows an admin add page. figure 6 shows an admin edit page. the admin pages were designed with flexibility in mind. main column headings may be sorted, as seen in figure 3, allowing one to locate a particular page. the sorting feature also displays the inner structure of the database that, in turn, identifies parent-child relationships between pages in the elrc, which is useful and necessary when adding pages to the elrc site. due to the careful thought used in creating the admin pages, they have proven to be extremely effective and useful in maintaining a library web site. each and every change to the site can be made on the web, allowing content to be edited remotely and eliminating the need for installing and maintaining expensive editing software on local and remote machines. usability testing with the site completed, the elrc felt it important to perform usability figure 1. elrc course guide template figure 2. public view of the elrc course guide template article title | author 173content management for the virtual library | salazar 173 tests, but how does a virtual library conduct usability testing when all of its students are distance education students? this is a difficult question that involves some ingenuity to answer. in order to solve this problem, staff members were propositioned (begged) to volunteer for the study. total staff acquired was five. also, a local college class of about ten students was persuaded to participate in the study. granted, the total number of subjects is not representative of the ncu student body; however, substantial changes to the site were made from the data gathered. more usability testing is expected in the immediate future. the findings usability testing complete, the site was launched. during this period, a few minor hang-ups were experienced, including broken links, form page errors, and stray design elements, but these were only minor problems that were quickly fixed. feedback from the elrc survey showed that nearly all of the students and faculty, roughly fifty respondents, approved of the changes by commenting that the site had improved in layout and organization of content as well as navigation. also, responses and comments from usability testing participants were equally positive and encouraging. figure 7 shows the new ncu learners elrc home page. although it is difficult to establish a direct connection between the elrc site and usage, recent statistics appear promising. since the inception of the new site in december 2004, the number of visits to the elrc learners home page has jumped 10 percent. this number is expected to rise as ncu continues to grow and students become more acquainted and familiar with the site. the project took nearly six months to complete and required the expertise of a programmer. although programming may be outside the requisites of a distance librarian, managing the site is not. a general understanding of control statements and sql is all that is needed. for the distance librarian who spends almost all of his or her time online, these skills can be acquired on the job or by taking introductory programming courses at a local college. in the hope that the site will continue to expand in concert with the growing body of ncu students, recently the elrc added a writing center and blog. with the entire site now being database driven, adding, updating, deleting content is done effortlessly. ideally, students and faculty will play a greater role in the development of the elrc site as a result of the changes. involving patrons with the site can play an integral, beneficial role in their academic pursuits. figure 3. web pages for elrc within a table figure 4. jspell iframe editor embedded within an admin edit page 174 information technology and libraries | september 2006 conclusion the elrc at ncu encourages other virtual or smaller libraries to explore their resources for improving their library web sites, which involves understanding campus resources and personnel. with the ever-burgeoning growth of technological resources, every library—small or large, virtual or physical, public or private—can empower itself to meet the needs of internet-savvy students. it is only a matter of being aware of the resources and putting them to good use. references and notes 1. the ncu elrc web site is comprised of three separate sites: the

the benefits of this outreach can be curtailed, however, by the significant staffing required to offer in-person tours. one academic library overcame this issue by turning to user experience research and gamification to provide an individualized online library orientation for four specific user groups: undergraduate students, graduate students, faculty, and community members. the library surveyed 167 users to investigate preferences regarding orientation format, as well as likelihood of future library use as a result of the gamified orientation format. results demonstrated a preference for the gamified experience among undergraduate students as compared to other surveyed groups. introduction background newcomers to the academic campus can be a bit overwhelmed by their unfamiliar environment: there are faces to learn, services and processes to navigate, and an unexplored landscape of academic buildings to traverse. whether one is an incoming student or recently hired employee of the university, all need to become quickly oriented to their surroundings to ensure productivity. in the midst of this transition, the academic library may or may not be on the list of immediate inquiries; however, the library is an important place to start. newcomers would be wise to familiarize themselves with the building and its services so that they can make optimal use of its offerings. two studies found that students who used the library received better grades and had higher retention rates. 1 another study regarding university employees revealed that untenured faculty made less use of the library than tenured faculty, a problem attributed to lack of familiarity with the library.2 researchers have also found that faculty will often express interest in different library services without realizing that these services are in fact available.3 it is safe to say that libraries cannot always rely on newcomers to discover the physical and electronic services on their own; they need to be shown these items in order to mitigate the risk of unawareness. in consideration of these issues, the walker library at middle tennessee state university (mtsu) recognized that more could be done to welcome its new arrivals to campus. the public university enrolls approximately 21,000 students, the majority of whom are undergraduates. however, with a carnegie classification of doctoral/professional and over one hundred graduate degree programs, there was a strong need for specialized research among the university’s graduate students and faculty. other groups needed to use the library too: non-faculty employees on campus as well as community users who frequently used walker library for its specialized and general collections. the authors realized that when new members of these different groups mailto:karen.reed@mtsu.edu mailto:a.miller@mtsu.edu information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 2 arrived on campus, few opportunities were available for acclimation to the library’s services or building layout. limited orientation experiences were conducted within library instruction classes, but these sessions primarily taught research skills and targeted freshman generaleducation classes as well as select upper-division and graduate classes. in short, it appeared that students, employees, and visitors to the university would largely have to discover the library’s services on their own through a search on the library website or an exploration of the physical library. it was very likely that, in doing so, the newcomers might miss out on valuable services and information. as mtsu librarians, the authors felt strongly that library orientations were important to everyone at the university so that they might make optimal use of the library’s offerings. the authors based this opinion on their knowledge of relevant scholarly literature as well as their own anecdotal experiences with students and faculty.4 the authors defined the library orientation differently from library instruction: in their view, an orientation should acquaint users with the services and physical spaces of the library, as compared to instruction that would teach users how to use the library’s electronic resources such as databases. the desired new approach would structure orientations in response to the different needs of the library’s users. for example, the authors found that undergraduates typically had distinct library interests compared to faculty. it was recognized that library orientations were time-consuming for everyone: library patrons at mtsu often did not want to take the time for a physical tour, nor did the library have the staffing to accommodate large-scale requests. the authors turned to the gamification trend, and specifically interactive storytelling, as a solution. interactive storytelling has previous applications in librarianship as a means of creating an immersive and self-guided user experience.5 however, no previous research appears to have been conducted to understand the different online, gamified orientation needs of various library groups. to overcome this gap, the authors developed an online, interactive, game-like experience via storytelling software to orient four different groups of users to the library’s services. these groups were undergraduate students, graduate students, faculty members (which included both faculty and staff at the university), and community members (i.e., visitors to the university or alumni); see figure 1 for an illustration of each groups’ game avatars. these groups were invited to participate in the gamified experience called libgo (short for library game orientation). after playing libgo, participants gave feedback through an online survey. this paper will give a brief explanation of the creation of the game, as well as describe the results of research conducted to understand the impact of the gamified experience across the four user groups. information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 3 figure 1. libgo players were allowed to self-select their user group upon entering the game. each of the four user groups was assigned an avatar and followed a logic path specified for that group. literature review traditional orientation searches for literature on library orientation yield very broad and yet limited details about users of the traditional library orientation method. it is important to note that the terms “library tour” and “library orientation” can be somewhat vague, because this terminology is not interchangeable, yet is frequently treated as such in the literature.6 these terms are often included among library instruction materials which predominately influence undergraduate students.7 kylie bailin, benjamin jahre, and sarah morris define orientation as “any attempt to reduce library anxiety by introducing students to what a college/university library is, what it contains, and where to find information while also showing how helpful librarians can be.”8 their book is a culmination of case studies of academic library orientation in various forms worldwide where the common theme across most chapters is the need to assess, revise, and change library orientation models as needed, especially in response to feedback, staff demands, and the evolving trend of libraries and technology.9 furthermore, the majority of these studies are undergraduate-focused, and often freshman-focused, while only a few studies are geared towards graduate students. other traditional orientation problems discussed in the literature include students lacking intrinsic motivation to attend library orientation, library staff time required to execute the orientation, and lack of attendance.10 additionally, among librarians there seems to be consensus that the traditional library tours are the least effective means of orientation, yet they are the most highly used and with attention predominately focused on the undergraduate population alone. 11 information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 4 in 1997, pixey anne mosely described the traditional guided library tour as ineffective, and documented the trend of libraries discontinuing it in favor of more active learning options.12 her study surveyed 44 students who took a redesigned library tour, all of whom were undergraduates (with freshmen as the target population). although mosely’s study only addressed one group of library users, it does attempt to answer a question on library perception whereby 93 percent of surveyed students indicated feeling more comfortable in using the library after the more active learning approach.13 a comparison study by marcus and beck looked at traditional vs treasure hunt orientations, and ultimately discovered that perception of the traditional method is limited by the selective user population and lack of effective measurements. they cited the need for continued study of alternative approaches to academic library orientation.14 a study by kenneth burhanna, tammy eschedor voelker, and julie gedeon looked at the traditional library tour from the physical and virtual perspective. confronted with a lack of access to the physical library, these researchers at kent state university decided to add an online option for the required traditional freshman library tour.15 their study compared the efficacy of learning and affective outcomes between face-to-face library tours and those of online library tours. of the 3,610 students who took the required library tour assignment, 3,567 chose the online tour method and 63 opted or were required to take the in-person, librarian-led tour. surveys were later sent to a random list of 250 students who did not take the in-person tour and the 63 students who did take the in-person tour. of the 46 usable responses all but one were undergraduates and 39 (85 percent) of them were freshman.16 this is a small sample size with a ratio of slightly greater than 2:1 for online versus in-person tour participation. although results showed that an instructor’s recommendation on format selection was the strongest influencing factor, convenience was also significant for those who selected the online option (81.5 percent). in contrast, only 18.5 percent of the students who took the face-toface tour rated it as convenient. the authors found that regardless of tour type, students were more comfortable using the library (85 percent) and more likely to use library resources (80 percent) after having taken a library tour. interestingly, students who took the online tour seemed slightly more likely to visit the physical library than those who took the in-person tour. ultimately the analysis of both tours showed this method of library orientation encourages library resource use, and the “online tour seems to perform as well, if not slightly better than the in-person tour.”17 gamification use in libraries an alternative format to the traditional method is gamification. gamification has become a familiar trend within academic libraries in recent years, and most often refers to the use of a technology based game delivery within an instructional setting. some users find gamified library instruction to be more enjoyable than traditional methods. for these people, gamification can potentially increase student engagement as well as retention of information.18 the goal of gamification is to create a simplified reality with a defined user experience. kyle felker and eric phetteplace emphasized the importance of user interaction over “specific mechanics or technologies” in thinking about the gamification design process.19 proponents of gamification of library instructional content indicate that it connects to the broader mission of library discovery and exploration as exemplified through collaboration and the stimulation of learning.20 additional benefits of gamification are its teaching, outreach and engagement functions.21 many researchers have documented specific applications of online gaming as a means of imparting library instruction. mary j. broussard and jessica urick oberlin described the work of librarians at lycoming college in developing an online game as one approach to teaching about information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 5 plagiarism.22 melissa mallon offered summaries of nine games produced for higher education, several of which were specifically created for use by academic libraries.23 many of these online library games reviewed used flash, or required players to download the game before playing. by contrast, j. long detailed an initiative at miami university to integrate gamification into the library instruction, a project which utilized twine.24 twine is an in-browser method and therefore avoids the problem of requiring users to download additional software prior to playing the game. other libraries have used online gamification specifically as a tool for library orientations. although researchers have demonstrated that the library orientation is an important practice in establishing positive first impressions of the library and counteracting library anxiety among new users, the differences between in-person versus online delivery formats are unclear.25 several successful instances have been documented in which the orientation was moved to an online game format. nancy o’hanlon, karen diaz, and fred roecker described a collaboration at ohio state university libraries between librarians and the office of first year experience; for this project, they created a game to orient all new students to the library prior to arrival on campus.26 the game was called “head hunt,” and was cited among those games listed in the article by mallon. 27 anna-lise smith and lesli baker reported the “get a clue” game at utah valley university which oriented new students over two semesters.28 another orientation game developed at california state university-fresno was noteworthy for its placement in the university’s learning management system (lms).29 in reviewing the literature regarding online library gamification efforts, there appear to be several best practices. several studies cite initial student assessment to understand student knowledge and/or perceptions of the content, followed by an iterative design process with a team of librarians and computer programmers.30 felker and phetteplace reinforced the need for this iterative process of prototyping, testing, deployment, and assessment as one key to success; however they also stated that the most prevalent reason for failure is that the games are not fun for users.31 librarians are information experts, and are not necessarily trained in fun game design. some libraries have solved this problem by partnering with or hiring professional designers; however for many under-resourced libraries, this is not an option.32 taking advantage of opensource tools, as well as the documented trial-and-error practices of others, can be helpful to newcomers who wish to break into new library engagement methods utilizing gamification. as literature has shown, a traditional library tour may have a place in the list of library services, but for whom and at what cost are questions with limited answers in studies done to date. gamification has offered an alternative perspective but with narrow accounts of its success in the online storytelling format and for users outside of the heavily focused freshman group. across all literature of library orientation studies, there is little reference to other library user populations such as faculty, staff, community users, distance students, or students not formally part of a class that requires library orientation. development of the library game orientation (libgo) libgo was developed by the authors with not only a consideration for the walker library user experience, but also with a specific attention to the differing needs of the multiple user groups served by the library. this user-focused concern led to exploring creative methodologies such as user experience research and human-centered design thinking, a process of overlapping phases that produces a creative and meaningful solution in a non-linear way. the three pillars of design information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 6 thinking are inspiration, ideation, and iteration.33 defining the problem and empathizing with the users (inspiration) led into the ideation phase, whereby the authors created lowand high-fidelity prototypes. the prototypes were tested and improved (iteration) through the use of beta testing in which playtesters interacted with the gamified orientation. the authors were novice developers of the gamified orientation, and this entailed a learning curve for not only the design thinking mindset but also the technical achievability. the development started with design thinking conversations and quickly turned to low-fidelity prototypes designed on paper. the development soon advanced to the actual coding so that the authors could get early designs tested before launching the final version. prior to deployment on the library’s website, libgo underwent a series of playtesting by library faculty, staff, and student employees. this testing was invaluable and led to such improvements as streamlining of processes and less ambiguity of text. libgo was developed with the twine open-source software (https://twinery.org), a product which is primarily used for telling interactive, non-linear stories with html. twine was an excellent application for this project as it allowed the creation of an online and interactive “choose your own adventure” styled library orientation game, in which users could explore the library based upon their selection of one of multiple available plot directions. with a modest learning curve and as an open source software, twine is highly accessible for those who are not accustomed to coding. for those who know html, css, javascript, variables, and conditional logic, twine’s capabilities can be extended. the library’s interactive orientation adventure requires users to select one of the four available personas: undergraduate student, graduate student, faculty, or community member. users subsequently follow that persona through a non-linear series of places, resources and points of interest built with the html output of using twee (twine’s programming language). see figure 2 for an example point of interest page and figure 3 for an example of a user’s final score after completing the gamified experience. once the twine story went through several iterations of design and testing, the html file was placed on the library’s website for the gamified orientation to be implemented with actual users. https://twinery.org/ information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 7 figure 2. this instructional page within libgo

own adventure" format whereby players progress through a storyline based upon their selection of one of multiple available plot directions. although the literature suggests that other technology-based methods are an engaging and instructive mode of content delivery, little prior research exists regarding this specific approach to library outreach. furthermore, no previous research appears to have been conducted to understand the different online, gamified orientation needs of various library groups. the researchers wanted to understand the potential of interactive storytelling as a means to educate a range of users on library services as well as make the library more approachable from a user perspective. the study was designed to understand the user experience of each of the four groups. the researchers hoped to discern which users, if any, found the gamified experience to be a helpful method of orientation to the library’s physical and electronic services. another area of inquiry was to determine whether this might be an effective delivery method by which to target certain segments of the campus for outreach. finally, the study intended to determine whether this method of orientation might incline participants toward future use of the library. methodology overview the authors selected an embedded mixed methods design approach in which quantitative and qualitative data were collected concurrently through the same assessment instrument.34 the survey instrument primarily collected quantitative data, however a qualitative open-response question was embedded at the end of the survey: this question gathered additional data by which to answer the research questions. each data set (one quantitative and one qualitative) was analyzed separately for each participant group, and then the groups were compared to develop a richer understanding of participant behavior. research questions the data collection and subsequent analysis attempted to answer the following questions: 1. which group(s) of library users prefer to be oriented to library services and resources through the interactive storytelling format, as compared to other formats? 2. which group(s) of library users are more likely to use library services and resources after participating in the interactive storytelling format of orientation? 3. what are user impressions of libgo, and are there any differences in impression based on the characteristics of the unique user group? participants participants for the study were recruited in-person and via the library website. in-person recruitment entailed the distribution of flyers and use of signage to recruit participants to play libgo in a library computer lab during a one-day event. online recruitment lasted approximately ten weeks and simply involved the placement of a link to libgo on the home page of th e library’s website. a total of 167 responses were gathered through both methods and participants were distributed as shown in table 1. information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 9 table 1. composition of study’s participants group number affiliation number of responses 1 undergraduate students 55 2 graduate students 62 3 faculty 13 4 staff 28 5 community members 9 total 167 for the purposes of statistical data analysis, groups 3 and 4 were combined to produce a single group of 41 university employee respondents; also, group 5’s data was not included in the statistical analysis due to the low number of participants. qualitative data for all groups, however, was included in the non-statistical analysis. survey instrument a survey with twelve total questions was developed for this study and was administered online through qualtrics. after playing libgo, participants were asked to voluntarily complete the survey; if they agreed, they were redirected to the survey’s website. before answering any survey questions, the instrument administered an informed consent statement to participants . all aspects of the research, including the survey instrument, were approved through the university’s institutional review board (protocol number 18-1293). the first part of the survey (see appendix a) consisted of ten questions, each with a ten-point likert scaled response. the first five questions were each designed to measure a preference construct, and the next five questions each measured a likelihood construct. the pref erence construct referred to participant’s preference for a library orientation: did they prefer libgo’s online interactive storytelling format, or did they prefer another format such as in-person talks? the likelihood construct referred to the participant’s self-perceived likelihood of more readily engaging with the library in the future (both in-person and online) after playing libgo. the second part of the survey gathered the participant’s self-reported affiliation (see table 1 for the list of possible group affiliations) as well as offered participants an open-ended response area for optional qualitative feedback. data collection the study’s data was collected in two stages. in stage one, libgo was unveiled to library visitors during a special campus-wide week of student programming events. on the library’s designated event day, the researchers held a drop-in event at one of the library’s computer labs (see figure 4 for an example of event advertisement). library visitors were offered a prize bag and snacks if they agreed to play libgo and complete the survey. during the three-hour-long drop-in session, 58 individual responses were collected: the vast majority of these came from undergraduate students (51 responses), with additional responses from graduate students (n = 4), university staff employees (n = 2), and one community member responding. community members were defined as anyone not currently directly affiliated with the university; this group may have included prospective students or alumni. stage 2 began the following day after the library drop-in event, and simply involved the placement of a link to libgo on the home page of the library’s website. any visitor to the library’s website could click on the advertisement to be taken to libgo. this link information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 10 remained active on the library website for ten weeks, at which point the final data was gathered. a total of 167 responses were gathered during both stages and participants were distributed as previously shown in table 1. figure 4. example of student libgo event advertisement results quantitative findings statistical analysis of each of the ten quantitative

from undergraduates, graduate students, and university employees (a group which combined both faculty and staff results) were utilized. a listing of mean comparisons by group, for each of the ten survey questions, may be found in table 2. the analysis of the one-way anovas yielded statistically significant results for three of the ten individual questions in the first part of the survey:

way to get introduced to the library’s services and resources?” the one-way anova found that there was a statistically significant difference between groups (f(2,155) = 3.714, p = .027, ω2 = .03). the post hoc comparison using the hochberg’s gt2 test revealed that undergraduates were statistically significantly more likely to prefer libgo in this manner (m = 8.13, sd = 1.94, p = .031) as information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 12 compared to the graduate students (m = 6.94, sd = 2.72). there was no statistically significant difference between undergraduates and the university employees (p = .145). according to criteria suggested by roger kirk, the effect size of .03 indicates a small effect in perceived usefulness of libgo as an introduction among undergraduates.35 question 3 asked “if your friend needed a library orientation, how likely would you be to recommend the game over other orientation options (such as in-person tours, speaking with a librarian, or clicking through the library website on your own)?” the one-way anova found that there was a statistically significant difference between groups (f(2, 155) = 4.508, p = .012, ω2 = .04). the post hoc comparison using the hochberg’s gt2 test found that undergraduates were statistically significantly more likely to prefer libgo over other orientation options (m = 7.38, sd = 2.49, p = .021) as compared to graduate students (m = 5.94, sd = 3.06). there was no statistically significant difference between undergraduates and university employees (p = .053). the effect size of .04 indicates a small effect regarding undergraduate preference for libgo versus other orientation options. question 6 asked “after playing this library orientation game, are you more or less likely to visit walker library in person?” the one-way anova found that there was a statistically significant difference between groups (f(2,155) = 7.178, p = .001, ω2 = .07). the post hoc comparison using the hochberg’s gt2 test revealed that undergraduates were statistically significantly more likely to visit the library after playing libgo (m = 8.27, sd = 2.09, p = .003) as compared to graduate students (m = 6.94, sd = 2.20). additionally, the test found that undergraduates were statistically significantly more likely to visit the library after playing libgo (p = .007) as compared to university employees (m = 6.90, sd = 2.08). according to criteria suggested by kirk, the effect size of .07 indicates a medium effect regarding undergraduate potential to visit the library in person after playing libgo. 36 in addition to testing each individual survey question, tests were run to understand the possible group differences by construct (preference and likelihood). the preference construct was an aggregate of survey questions 1-5, and the likelihood construct was an aggregate of survey questions 6-10. for both constructs, the one-way anova found results which were not statistically significant. in all, the quantitative findings indicated three areas by which the experience of playing libgo was more helpful for the surveyed undergraduates than the other surveyed groups (i.e., graduate students or university employees). at this point, the analysis turned to the qualitative data so as to better understand participant views of libgo. qualitative findings analysis of the qualitative results was limited to the data collected in the survey’s final question. question 12 was an open-response area, and was intentionally prefaced with a vague prompt: “do you have any final thoughts for the library (suggestions, additions, modification, comments, criticisms, praise, etc.)?” of the 167 total survey responses, 67 individuals chose to answer this question. preliminary analysis showed that the feedback derived from this question covered a spectrum of topics, ranging from remarks on the libgo experience itself to broader concerns regarding other library services. open coding strategies were utilized to interpret the content of participant responses. under this methodology, the responses were evaluated for general themes and then coded and grouped information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 13 under a constant comparative approach.37 nvivo 12 software was used to code all 67 participant responses. initial coding yielded eight open codes, but these were later consolidated into six final codes (see table 4). one code (libgo improvement tip) was rather nuanced and yielded five axial codes (see table 5). axial codes denoted secondary concerns which fell under a larger category of interest. although some participants gave longer feedback which addressed multiple concerns, care was taken to segregate each distinct concern to a specific code. therefore, it is important to note that some comments addressed multiple concerns, and so the total number of concerns (n = 76) is greater than the total number of individuals responding to the prompt (n = 67). table 4. distribution of qualitative codes

concerns). affirmative comments regarding libgo were primarily split between undergraduate and graduate students, with a small number of comments coming from the other groups. although all groups stated that the game was helpful, one undergraduate wrote “i wish i would’ve received this orientation at the very beginning of the year!” a graduate student declared “this was a creative way to engage students, and i think it should be included on the website for fun.” both community members commented on the utility of libgo in providing an orientation without having to physically come to the library; for example, “interactive without having to actually attend the library in person which i liked.” additionally, a community member pointed out the instructional capability of libgo, writing “i think i learned more from the game than walking around in the library.” negative feedback (6 separate concerns). unfavorable comments regarding libgo primarily challenged the orientation’s characterization as a “game” in terms of its lack of fun. one graduate student wrote a comment representative of this concern by stating, “the game didn’t really seem like a game at all.” a particularly searing comment came from a university staff member who information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 14 wrote, “calling this collection of web pages an ‘interactive game’ is a stretch, which is a generous way of stating it.” in-person tour preference (6 separate concerns). a small number of concerns indicated a preference for in-person orientations versus online. one undergraduate cited the ability to ask questions during an in-person tour as an advantage of that delivery medium. a graduate student mentioned their desire for kinesthetic learning over an online approach, writing, “i prefer hands on exploration of the library.” libgo improvement tip (23 separate concerns). suggested improvements to libgo were the largest area of qualitative feedback and produced five axial themes (subthemes); see table 5 for a breakdown of the five axial themes by group. 1. design issues were the largest cited area of improvement, and the most commonly mentioned design problem was the inability of the user to go back to previously seen content. although this functionality did in fact exist, it was apparently not intuitive to users; design modifications in future iterations are therefore critical. other users made suggestions as to the color scheme used and the ability to magnify image sizes. 2. user experience was another area of feedback, and primarily included suggestions on how to make libgo a more fun experience. one graduate student offered a role-playing game alternative. another graduate student expressed an interest in a game with side missions, in addition to the overall goals, where tokens could be earned for completed missions; the student justified these changes by stating “i feel that incorporating these types of idea will make the game more enjoyable.” in suggesting similar improvements, one undergraduate stated that libgo “felt more like a quiz than a game.” 3. technology issues primarily addressed two related issues: images not loading and broken links. images not loading could be dependent on many factors, including the user’s browser settings, internet traffic (volume) delaying load time, or broken image links, among others. broken links could be the root issue since the images used in libgo were taken from other areas of the library website. this method of gathering content pointed out a design vulnerability of using existing image locations (controlled by non-libgo developers) rather than images exclusively for libgo. 4. content issues were raised exclusively by graduate students. one student felt that libgo placed an emphasis on physical spaces in the library and did not give a deep enough treatment to library services. another graduate student asked for “an interactive map to click on so that we physically see the areas” of the library, thus making the interaction more user-friendly with a visual. 5. didn’t understand purpose is a subtheme where improvement is needed and is based on two comments made by the two university staff members. one wrote that “an online tour would have been better and just as informative,” although libgo was not only designed to be an online tour of the library, but also an orientation of the library’s services. the other staff member wrote, “i read the rules but it was still unclear what the objective was.” in all, it is clear that libgo’s purpose was confusing for some. information technology and libraries september 2020 applying gamification to the library orientation | reed and miller

feedback on general library services rather than on libgo itself. undergraduates simply gave general positive feedback about the value of the library, but many graduate students gave recommendations regarding specific electronic resource improvements. additionally, one graduate student wrote, “i think it is critical to meet with new graduate students before they start their program,” something the library used to do but had not pursued in recent years. although these comments did not directly pertain to libgo, the authors accepted all of them as valuable feedback to the library. library building feedback (11 separate concerns). this was another theme in which graduate students dominated the comments. feedback ranging from requests for microwave use, additional study tables and better temperature control in the building appeared. several participants asked for greater enforcement of quiet zones. like the library services feedback, the authors again took these comments as helpful to the overall library rather than libgo. discussion the results of this study indicated that some groups of library visitors better received the gamified library orientation experience than other groups. undergraduate students indicated the largest appreciation for a library orientation via libgo. specifically, they demonstrated a statistically significant difference over the other groups in supporting libgo’s usefulness as an orientation tool, a preference for libgo over other orientation formats, and a likelihood of future use of the physical library after playing libgo. these very encouraging results provide evidence for the efficacy of alternative means of library orientation. the qualitative results provided additional helpful insight regarding the user impressions from each of the five surveyed groups. this feedback demonstrated that a variety of groups benefited from the experience of playing libgo, including some community members who appreciated libgo as a means of becoming acclimated to the library without having to enter the building. a virtual orientation format was not ideal for a few players who indicated a preference for a face-toface orientation due to the ability to ask questions. many people identified areas of improvement for libgo. graduate students in particular offered a disproportionate number of suggestions as compared to the other groups. while they provided a great deal of helpful feedback, it is possible that graduate students were so distracted by the perceived problems that they could not fully take in the experience or gain value from libgo’s orientation purpose. it is also very likely that libgo information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 16 simply was not very fun for these players: several players noted that it did not feel like a game but rather a collection of content. the review of literature indicated that this amusement issue is a common pitfall of educational games. although the authors tried to design an enjoyable orientation experience, it is possible that more work is needed to satisfy user expectations. the mixed-methods design of this study was instrumental in providing a richer understanding of user perceptions. while the statistical analysis of participant survey responses was very helpful in identifying clear trends between groups, the qualitative analysis helped the authors draw valuable conclusions. specifically, the open-response data demonstrated that additional groups such as graduate students and community members appreciated the experience of playing libgo; this information was not readily apparent through the statistical analysis. additionally, the qualitative analysis demonstrated that many groups had concerns regarding areas of improvement that may have impaired their user experience. these important findings could help guide future directions of the research. in all, the authors concluded this phase of the research feeling satisfied that libgo showed great promise for library orientation delivery but could benefit from continued development and future user assessment. although undergraduate students seemed most receptive overall to a virtual orientation experience, other groups appeared to have benefited from the resource. study limitations a primary limitation of this study was its small sample size. as the entire university campus was targeted for participation in the study, the number of respondents was far too small to generalize the results. despite this limitation however, the study’s population reflected many different groups of library patrons on campus. the findings are therefore valuable as a means of stimulating future discussion regarding the value of alternative library orientation methods utilizing gamification. another limitation is that the authors did not pre-assess the targeted groups for their prior knowledge of walker library services and building layout, nor for their interest in learning about these topics. it is possible that various groups did not see the value in learning about the library for a variety of reasons. faculty members, in particular, may have considered their prior knowledge adequate for navigating the electronic holdings or building layout without recognizing the value of the other many services offered physically and electronically by the library. all groups may have experienced a level of “library anxiety” that prevented them from being motivated to learn more about the library.38 it is difficult to understand the range of covariate factors without a pre-assessment. finally, there was qualitative evidence supporting the limitation that libgo did not properly convey its stated purpose of orientation rather than imparting research skills. without understanding libgo’s focus on library orientation, users could have been confused or disappointed by the experience. although care was taken to make this purpose explicit, some users indicated their confusion in the qualitative data. this observed problem points to a design flaw that undoubtedly had some bearing on the study’s results. conclusion & future research convinced of the importance of the library orientation, the authors sought to move this traditional in-person experience to a virtual one. the quantitative results indicated that the gamified information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 17 orientation experience was useful to undergraduate students in its intended purpose of acclimating users to the library, as well as encouraging their future use of the physical library. at a time in which physical traffic to the library has shown a marked decline, new outreach strategies should be considered.39 the results were also helpful in showing that this particular iteration of the gamified orientation was preferred over other delivery methods by undergraduate students, as compared to other groups, to a statistically significant level. this is an important finding as it demonstrates that a diversified outreach strategy is necessary: different groups of library patrons desire their orientation information in different formats. the next logical question to ask however is: why did the other groups examined through the statistical data analysis (graduate students and faculty) not appreciate the gamified orientation to the same level as undergraduates? the answers to this question are complicated and may be explained in part by the qualitative analysis. based upon those findings, it is possible that the game did not appeal to these groups on the basis of fun or enjoyment; this concern was specifically mentioned by graduate students. faculty members, including staff, provided a smaller level of qualitative feedback; it is therefore difficult to speculate as to their exact reasons for disengagement with libgo. with this concern in mind, the authors would like to concentrate their next iteration of research on the specific library orientation needs of graduate students and faculty. both groups present different, but critical, needs for outreach. graduate students were the largest group of survey respondents, presumably indicating a high level of interest in learning more about the library. many graduate programs at mtsu are delivered partially or entirely online; as a result, these students may be less likely to come to campus. due to graduate students’ relatively infrequent visits to campus, a virtual library orientation could be even more meaningful for them in meeting their need for library services information. faculty are another important group to target because if they lack a full understanding of the library’s offerings, they are unlikely to assign assignments that wholly utilize the library’s services. although it is possible that faculty prefer an in-person orientation, many new faculty have indicated limited availability for such events. a virtual orientation seems conducive to busy schedules. however, it is possible that the issue is simply a matter of marketing: faculty may not know that a virtual option is available, nor do they necessarily understand all that the library has to offer. in all, future research should begin with a survey to understand what both groups already know about the library, as well as the library services they desire. another necessary step in future research would be the expansion of the development team to include computer programmers. although the authors feel that libgo holds great promise as a virtual orientation tool, more needs to be done to enhance the user’s enjoyment of the experience. twine is a user-friendly software that other librarians could pick up without having to be computer programmers; however, programmers (professional or student) could bring a design expertise to the project. future iterations of this project should incorporate the skills of multiple groups, including expertise in libraries, user research, visual design, interaction design, programming, marketing, and testers from each type of intended audience. collectively, this group will have the greatest impact on improving the user experience and ultimately the usefulness of a gamified orientation experience. this experience with gamification, and specifically interactive storytelling, was a valuable experience for walker library. these results should encourage other libraries seeking an alternate information technology and libraries september 2020 applying gamification to the library orientation | reed and miller 18 delivery method for orientations. the authors hope to build upon the lessons learned from this mixed methods research study of libgo to find the correct outreach medium for their range of library users. acknowledgments special thanks to our beta playtesters and student

this project was to identify the impact of the covid-19 pandemic on the spatiotemporal distribution of the library’s online patrons, so that we could assess if the scheduled library reference hours are meeting the needs of the academic community. we collected each online reference patron’s location information via their ip address, as well as the timestamp of each online reference instance. the spatiotemporal distribution patterns were analyzed and compared before and after in-person instruction was suspended due to covid-19 distance protocols and a closing of the campus in the 2020 spring semester. the results show that the geographic origins of reference questions redistributed after covid-19 protocols were initially implemented and the university community underwent a temporary geographical redistribution. reference question origins tended to move away from campus to other areas of the state, other states, and internationally. this population redistribution suggested that the library could adjust the online reference schedule to provide better access and service to patrons. introduction the library’s online reference service, also referred to as library chat or digital reference, is a synchronous text-based interaction between the library and the patron via an internet connection, though audio/video communications are now also available. this online reference service provides a way to meet the information needs of patrons who cannot access the physical library location or prefer virtual communication. in this way, it expands the library’s reference services from the physical location to a virtual environment. when the university community was encouraged to socially distance due to covid-19, online reference became a key library function that maintains the library’s connection to the community and their information needs. this connection became vital when most of the library’s physical services were suspended for a short period during the 2020 spring semester. for many libraries, chat became the only possible way to connect with patrons. this increased reliance on online reference and the greater dispersion of the student population led to a looming assessment question with regard to the service: are the hours of online reference convenient for the populations that may live in time zones other than the library’s local time? that is to say, are we available when our patrons are likely to need us? to address the above questions, this study recorded the time stamp and ip address associated with every incoming chat reference from the beginning of the 2019 fall semester to the end of the 2020 fall semester. we evaluated and compared the information from the spatiotemporal distribution pattern change of online reference patrons before and during the covid-19 pandemic. an ip address is a unique string of numeric characters that identifies a particular computer or user over a network, and this number is generally saved in the background with all other information about the chat reference interaction. the ip addresses can be translated to mailto:tgerrish@purdue.edu mailto:kongn@purdue.edu information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 2 gerrish and kong latitude and longitude information using geocoding services. with the latitude and longitude coordinates derived from the ip address, we determined a patron’s location at a city level and time zone. thus, the information helped to evaluate the user population distribution in the world and compare users’ local times to the online reference service’s operation hours. the patrons’ location information as well as the timestamps were evaluated and analyzed in geographic information systems (gis) to provide insights about how the online reference service met the user needs and how the library could improve, if possible. background purdue university libraries serves a large r1 university with a student population of 45,869 as of fall 2020. the online reference service is staffed by approximately 20 professional staff, though this number jumped to 29 when the library’s physical locations closed due to covid-19. online reference at our libraries uses the springshare platform for synchronous chat service with the university community. covid-19 has had a measured effect on online reference hours of operation. prior to covid-19, online reference operated from 11 a.m. to 9 p.m., monday through thursday. on fridays, online reference operated from 11 a.m. to 5 p.m. sundays had truncated hours with the service open from 6 p.m. to 10 p.m. immediately following the move to virtual instruction in march 2020, the administration requested that the online reference service reflect the original hours of the physical library as closely as possible. thus, online reference hours of operation shifted to 7:30 a.m. to 10 p.m. with staff who normally cover the physical reference desks now covering the online service. additional hours were added on saturday afternoon, from 1 p.m. to 5 p.m., and sunday hours were extended from 1 p.m. to 10 p.m. during the university’s virtual instruction phase, only one physical library maintained limited hours of operation, from 8 a.m. to 5 p.m. for local students who needed a computer, wi-fi access, or printing. this was the only in-person service available until august 2020, when libraries began opening with covid-19 restrictions in place. during summer 2020, online reference opening time was moved back to 9 a.m. to allow staff to cover the operations of the library, but the evening and weekend hours were maintained. finally, in fall 2020, all physical libraries reopened with operating hours from 7 a.m. to 12 a.m. however, online reference hours did not return to the 2019 model. instead, online reference operated from 9 a.m. to 11 p.m., monday through thursday; 9 a.m. to 5 p.m. on friday; 1 p.m. to 5 p.m. on saturday; and 2 p.m. to 11 p.m. on sunday. figure 1 shows the timeline of the physical libraries operating status and online reference operating hours changes in 2020. prior to covid-19, this reference service mirrored the traditional in-person reference desk in the hours of operation and staff support. indeed, it was originally conceived, structured, and promoted as a supplement to the in-person reference desk, which was stationed at each library. after campus-wide covid-19 restrictions went into place in march 2020, on-campus students were asked to return home. all of the physical libraries except one were closed, and patrons were actively directed to online reference services. as a result, this service underwent changes in its availability and how users accessed it. while the service was already increasing in use, the postcovid-19 period observed a 30% increase as it became more widely used by not only the student population but also the faculty and staff. at this point, online reference became the primary connection between the geographically distributed community and the library. on march 23, 2020, all classes became virtual, and students largely departed campus. this dispersion was not information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 3

faculty and staff communities also relocated once it was clear that work would need to be done remotely. in the fall 2020 semester, university classes resumed with a hybrid online/in-person structure. of the total 45,869 students enrolled as of fall 2020, approximately 4,900 students (or 10.7% of the student population) elected online only classes for at least one semester. given that online reference would still have a schedule of 9 a.m. to 11 p.m., sunday through friday, the question became does this serve the students who were potentially located in time zones geographically distant from the university. literature review online reference service has been offered in academic libraries for more than three decades.1 projects that evaluate online reference service, along with technology changes and user community needs, have been conducted ever since.2 for example, mcclure et al. provided a guideline of statistics, measures, and quality standards for evaluating online reference services.3 however, not many studies have been done that assess the needs from patrons’ geographic perspective in order to improve the service. applying gis analysis to improve the library’s services has a comparatively long history. most of those studies are about mapping the interior spaces of libraries and understanding both space and facility use by patrons. among the representative articles, xia used gis to map the physical location of library materials against a user’s self-height to gain a better understanding of patron browsing habits.4 weessies used gis to evaluate the likelihood of a computer station’s use in relation to the distance to the library entrance, windows, printers, number of neighbo ring computers, and library service locations.5 given6 and mandel7 combined the traditional library metric of user counts from “visual sweeps” with gis to visualize library space usage, patron preferences, and traffic flow. complementing this, stoddart mapped library spaces against the expected use to visualize how library space was used.8 shen takes the space model a step further information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 4 gerrish and kong by creating a library-space information model that can direct patrons to the shelf location of a given book while also giving the library data on circulation stats vs. book location and shelf height.9 characteristic for this broad grouping of research is the use of gis to analyze patrons, patron behavior, and library resources within the extent of the brick and mortar library building. spaces outside of library buildings have been less examined. historically, the external space of the library has been important with regard to neighborhood service areas, wayfinding, distribution of reference within a consortium, and coverage over larger geographic areas. while many studies focused on the community and a library’s immediate locality and community, donnelly mapped library geographic dispersion on the national level against existing united states populations to examine the variation in local library coverage.10 with the implementation of covid-19 procedures and the ubiquity of online reference services, the external location of patrons and their change in distribution over time has increasingly become an important question that gis can address. there are limited studies using patron information, including ip addresses, to track patron location within an online reference model. in one example, clark geocoded patron addresses to visualize the library’s external service area.11 in an academic library setting, ruttenberg used the ip address to locate on-campus patrons when they asked a question to online reference.12 kinikin studied patron locations in the world and used gis to determine which populations were using the library and its branches while also informing decision makers on areas of low library coverage.13 these ideas were expanded in mon’s study, which geolocated ip addresses for the physical location of a patron who asked a question within the statewide florida electronic library collaborative chat service.14 building on this, bishop compared the originating location of a question against which librarian in a geographically disperse network asked the question as a measure of the utility of local knowledge in the reference process.15 in our study, we expanded upon the previous methods to compare patrons’ spatiotemporal pattern changes before and after the covid-19 pandemic. methods purdue university libraries online reference service uses springshare’s libanswers platform as an interface for chat. the system records each patron’s message text, timestamp, as well as the associated ip address. an initial data set of all online reference questions dated from fall semester 2019 until the end of fall semester 2020 (inclusive august 19, 2019, to december 15, 2020) was downloaded from the libchat administration function as a .csv file. this initial data set included fields for ip address, date, time, interaction transcript, patron email (if provided), and name (if provided). this initial data set included 8,754 chat interactions excluding emails, sms text transactions, and questions asked via twitter. all reference interactions were initiated from the library’s website, the ask-a-librarian page, or through the proactive chat widget, which is located on all purdue library webpages. we do not require patrons to identify their relation to the university, their email address, or their status in the university (i.e., undergraduate student, faculty, staff, etc.), so this information is generally unavailable unless the patron self-identifies through the course of the reference interaction. similarly, unless a patron identifies their physical location, reference staff generally do not know where in the world an online reference patr on is located. in practice, most incoming online reference questions are anonymous with no indicators of identity or location. information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 5 gerrish and kong the database was geocoded using the ipinfodb tool to get latitude and longitude information.16 per ipinfodb, the platform’s accuracy is “99.5% on a country level and around 60% on a city level for the us within a 25-mile radius.” the date and timestamps were also associated with the output file. the latitude and longitude coordinates were translated to city, region (i.e., state), and country. time zone information was added to each record according to its geographic location. the final data set contained separate fields for latitude, longitude, state or region, country, time zone, and timestamp, which includes both date and time. at this point, all personal information embedded in the original data set was de-identified, though certain conversations could potentially identify users. one potential limitation to the data set is that if a patron used the university’s vpn network, the reference interaction would be georeferenced with an ip address on campus. indeed, any vpn network would not report the reference interaction’s originating location correctly. the data from each semester was broken down and sorted separately. in addition, r ecords in spring semester 2020 for both preand post-covid-19 restrictions were compared to measure the redistribution of a question point of origin due to covid-19. the data were spatially plotted and analyzed using arcgis pro. results figure 2. total digital reference transactions per semester. 0 500 1000 1500 2000 2500 3000 fall 2019

6 gerrish and kong the digital reference transaction data were compiled and analyzed on a semester basis except for spring 2020, when all classes moved to 100% online on march 23, 2020. for the spring 2020 semester, the data were split into pre-march 23 (i.e., pre-covid-19 restrictions) and post-march 23 (i.e., post-covid-19 restrictions). the total number of chat interactions generally grew for each semester starting with fall 2019 (fig. 2). the number of summer chat interactions was relatively fewer because it was a shorter semester with fewer students taking classes as compared to the fall and spring semesters. we analyzed the spatial and temporal distribution of patrons before and after the covid-19 pandemic in the following sections. spatial distribution of the patrons before and after implementation of covid-19 protocol the spatial distributions of digital reference patrons before and after the pandemic are mapped in figure 3. there is a trend showing that after the start of the pandemic, patrons were more geographically distributed within the unites states and around the world. we mapped the international distribution of patrons in fall semester of 2019 and 2020 (see fig. 3(a) and 3(b)), as most of the international students make their travel plans by semester. there is a significant increase in questions coming from india, several european countries, and south america. we compared the spatial distribution of patrons before and after the implementation of covid-19 protocols in spring 2020 within the united states as the time frame is more suitable for domestic travel plans. figure 3(c) and 3(d) also show an increase of patrons around the country other than the campus area. figure 3. spatial distribution of patrons before and after initial covid-19 protocols closed the campus.

reference during the time of covid-19 7 gerrish and kong to help us further understand this spatial distribution change, we divided the geographic regions into four categories: local areas (west lafayette and lafayette areas of indiana, where the purdue university main campus is located), other indiana areas, other states apart from indiana, and areas outside of the united states. the transactions in these four regions are shown in table 1, and the percentages of transactions from each region were summarized in figure 4. in fall 2019, which is considered the last “normal” semester prior to the covid-19 response, 60% of reference questions originated in the immediate local area to campus (defined as the local area). the beginning of spring 2020 followed closely to this number with 56% of the total questions originating in the local area of the university. this proportion dropped at the march 23 boundary with only 29% of reference questions originating from the immediate local area to the university. during this period, there was an increase in questions originating in the state of indiana as well as other regions of the united states and the world. during summer 2020, 35% of the total number of chats originated in the campus area. in fall 2020, classes were offered as a combination of hybrid, in-person, and virtual formats; however, the proportion of questions originating in the immediate area did not return to fall 2019 levels. instead, only 43% of questions originated from the campus area. figure 4. the percentage of transactions before and

international locations. fall 2019 saw 11% of virtual reference questions originating in indiana but outside of the local area. this increased to 18% in spring 2020 prior to the implementation of campus covid-19 restrictions. after march 23, 2020, when all classes went online, the percentage of questions in indiana outside of our campus area rose to 31%. this proportion remained steady during summer 2020, when 29% of questions originated in indiana outside of the local area. in fall 2020, when in-person classes resumed, the proportion dropped to 26%, but this remains more than two times the proportion measured during fall 2019. this pattern of redistribution of geographic origin was repeated in the data points outside the united states, though the fluctuation due to covid-19, while similar, occurred to a lesser degree. in fall 2019, 3.9% of questions arrived from geographic origins outside of the united states. in spring 2020, prior to covid-19 restrictions, this number dropped to 2.9%. after classes went virtual and students moved off campus, the percentage of questions increased to 5.2%. in fall 2020, the proportion dropped to 4.9%, but this is still not a return to fall 2019 levels. the distance of digital reference patrons to main campus to analyze the spatial distribution change of digital reference patrons, we calculated the distance of each patron to our main campus. a small portion of ip addresses (less than 4%) which couldn ’t be correctly located was excluded from the analysis. figure 5 represents the distance distributions in a box and whisker diagram. the horizontal lines within the boxes show the median of the data sets. in both fall 2019 and early spring 2020, the median distances are about 400 miles or less, which is within the local area. this indicates that most of the digital reference questions come from patrons who live around the main campus. the median distance increased to 1,000 miles after classes were moved online in spring 2020, which is about the typical distance of traveling within the state of indiana. the maximum value was extremely high coming from international countries. this indicates that a significant portion of the patrons moved outside of the local area. in fall 2020, although the maximum distance dropped to a similar range as in normal semesters, the median and average values of the distance dataset are still much higher than the time before the pandemic. information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 9 gerrish and kong figure 5. the box and whisker diagram shows the distance from ip addresses to campus (in miles). to test the statistical significance of the distance values in different time periods, we conducted anova tests for the distances in spring 2020 semester comparing before and after the pandemic, as well as a comparison between fall 2019 and fall 2020. the test results are shown in table 2. both tests show there are significant differences before and after the classes were moved online. this means the pandemic situation significantly changed the patron distances to the main campus with p-values < 0.05. we likewise compared the distance between spring 2020 post-pandemic and fall 2020. there was no significance found. although the university started to offer in-person classes in fall 2020, and most of the students were back to campus, there were still quite a few questions coming from students/faculty who were not living in the geographic area around campus. information technology

questions helped us to plan the digital reference service hours to better meet patrons’ needs. we analyzed the temporal distribution of questions by the day of the week for fall 2019 and fall 2020. figure 6 shows the median distances of the questions for each day of the two semesters. the distance was broken down into six ranges differentiated by color. from the nearest distance range to the ranges above, the analysis covers the questions coming around campus, in the local area within indiana, around eastern united states (with mostly eastern and central time zones), the entire united states, and international locations. in fall 2019, we provided digital reference service sunday through friday, and in fall 2020, the service was provided every day except holidays. in fall 2019, the monday to friday range showed that most digital reference questions came from the campus area, especially in the first half of the semester. questions from further distances within indiana started to occur more often after november, probably due to holiday related travels. relatively remote questions came more often on sundays. one possible explanation for this difference is that students/faculty might travel away from campus during weekends. interestingly, the fall 2020 weekly distribution of questions shows a different pattern. first, most median distances are further than the fall 2019 semester, which means there were a lot of questions coming from people living off campus, no matter if it was at the beginning of the semester or later. second, there was no obvious difference between the median distances during the weekdays and weekends. information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 2 gerrish and kong figure 6. the median distance of reference questions in miles by weekdays (left: fall 2019, right: fall 2020). in addition, we analyzed the hourly distributions of digital reference questions for fall 2019 and fall 2020 (fig. 7). in fall 2019, the median distance of the questions were mostly from campus, especially during the peak hours. if the median distances measured were not from the campus area, at most they were located in the local area where most of the off-campus students, faculty, staff, and research community live, or within greater lafayette. remote questions came from different time zones, such as international time zones or the pacific time zone, and usually came either in the first hour or the last hour of digital reference service operating hours. in fall 2020, this distribution pattern changed. most of the median distance ranged 200 miles, which meant that a large portion of the questions came from off-campus populations. there were additional time slots with median distances above 2,000 miles, which came from a time zone with at least 2 hours difference from our campus. again, these questions were most often observed in either early or late reference service hours, i.e., 8 a.m. to 9 a.m., or 10 p.m. to 11 p.m. <= 5.6 <= 22 <= 188 <= 500 <= 2,000 >2,000 information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 3 gerrish and kong figure 7. the median distance of reference questions by hour of day (eastern time zone). discussion and conclusion covid-19 and the protocols developed in response to it had a redistributing effect on the geographic origin of reference questions in academic libraries. as the university closed and moved to virtual classes in response to the early pandemic, the geographic origin of reference questions redistributed away from campus. in our case, the geographic origins tended to move away from the campus to nearby areas within the state and neighbor states, though there was redistribution away from the campus at the state, regional, national, and international level. as of fall 2020, when the campus partially opened, these numbers have begun reversing themselves, but there is still a (a) fall 2019 median distance in miles (b) fall 2020 median distance in miles <= 5.6 <= 22 <= 188 <= 500 <= 2,000 <= 5.6 <= 22 <= 188 <= 500 <= 2,000 information technology and libraries december 2022 spatiotemporal distribution change of online reference during the time of covid-19 4 gerrish and kong significant population beyond the campus and the local time zone. fall 2020 distribution numbers still show some of the redistribution effects observed early in the pandemic. there were a surprising lack of questions coming from the russian federation, china, and central asian countries given that our university does have students from these countries. this may be due to the use of a vpn by users in these countries when accessing library resources. if a user were to use vpn, the question would be recorded as having a geographic origin in the vpn provider’s location, rather than in the country of origin. this is one possible explanation for the lower number observed in china and the non-existent users in the russian federation, eastern europe, and central asia. this study demonstrated the broadening of our library’s geographic footprint in response to covid-19 protocols. students, faculty, and staff were not bound to campus and were free to study and work anywhere with internet access. in this regard, with populations distributed around the country and world, the expansion of reference hours was necessary. prior to covid-19, online reference operated from 11 a.m. to 9 p.m. this would mean students studying virtually in the pacific time zone would experience effective reference desk hours of 8 a.m. to 6 p.m., which eliminates access during the evening hours. when the library extended online reference hours during the covid-19 lockdown from 7:30 a.m. to 10 p.m., this somewhat improved the accessibility for patrons in the pacific time zone. for those students studying online in the pacific time zone, this creates effective reference hours of 4:30 a.m. to 7:00 p.m. pst. the contrast becomes even starker when examining international students studying online in much more distant countries. many students from india returned to their home country in spring 2020 following the move to virtual learning. for students studying in india, the online reference desk in pre-covid-19 times would have effective hours 8:30 p.m. to 6:30 a.m. ist (india standard time), which forced this population to interact with the library during their evenings and nights. the expanded reference hours improved this access to 5 p.m. to 7:30 a.m. ist. while this is better, it still forces students in this part of the world to interact with the library during the evenings and nights and excludes daytime hours. interestingly, the data from fall 2019 seems to indicate that there was an international population prior to covid-19. these were likely students studying abroad, taking some of the early online classes, or simply traveling. thus, the distributed online reference user population is nothing new but has been exacerbated by covid-19 and the expansion of online classes. in this regard, the number of international reference interactions can be predicted to decrease as covid-19 restrictions are gradually relaxed, but the number will not go to zero. endnotes 1 joseph janes, david carter, and

article focuses on the problematic democratization of small museum collections online in cyprus. while the web has enabled cultural heritage organizations to democratize information to diverse audiences, numerous small museums do not enjoy the fruits of this digital revolution; many of them cannot democratize their collections online. the current literature provides insight into small and large museums’ challenges worldwide. however, we do not have any knowledge concerning small cypriot museums. this article aims to fulfill this gap by raising the following research question: what is the current state of small museum collections online in cyprus, and what challenges do they face in democratizing their collections online? we present our empirical results from the interview summaries gathered from six small museums. introduction cultural heritage digitization and online accessibility offer an unprecedented opportunity to democratize museum collections. online collections, typically presented on institutional websites, represent the world’s culture, an increasing trend toward a world where information is digitally preserved, stored, accessed, and disseminated instantaneously through a global and interconnected digital network. consumers search for information on the web has enabled cultural heritage institutions to democratize their collections online, yet most small museums have not benefited from this process and do not have their collections online. as a result of the above-mentioned problem, digital versions of small museum collections are primarily inaccessible, meaning less access to information “knowledge.” there is a clear need for small museums to remain relevant by publishing their collections online. small museums must move quickly into the digital world. current literature provides insights into the challenges they face worldwide. however, we do not have knowledge regarding the situation in cyprus. this study aims to fill this gap by researching small museums in cyprus and asking the following research question: what is the current state of small museum collections online in cyprus, and what challenges do they face in democratizing their collections online? what is a small museum? museums are defined as small based on their annual budget and number of staff. the american association for state and local history (aaslh) defines museums as small if they have an annual budget of less than $250,000 and limited staff with multiple responsibilities. other factors such as the size of collections and the physical size of the museum could further categorize a museum as small. katz set the same budget and set the staff number at five or less.1 honeysett and falkowski put the budget at $300,000 and five or fewer employees.2 miller notes that the average small mailto:a.avgousti@cyi.ac.cy mailto:gpapaioa@ionio.gr information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 2 avgousti and papaioannou museum has just two full-time employees and a budget of less than $90,000.3 watson by contrast defines small museums as ones that grew out of the community they serve. 4 for the purposes of this article, a small museum is one with more than one but less than five fulltime employees not including museum custodians. categorizing a museum based on its budget is difficult and contentious since often museum staff are funded by another body, such as a municipality. literature review cultural heritage institutions such as galleries, libraries, archives, and museums (glams) were among the first organizations to digitize information by creating databases whose access was granted locally to institutional cardholders (horan, 2013). the process of digitization is of paramount importance, with museums eager to offer online access to their physical collections .5 online collections provide a range of opportunities, including the facilitation of knowledge sharing and the creation of a participatory environment that promotes information exchange.6 through their online presence, museums can present their collections to a global audience.7 the accessibility of digital knowledge opens the door for further knowledge to be generated and enhances the educational reach of cultural institutions.8 online collections create opportunities for small and geographically isolated museums to deliver learning opportunities to audiences around the world, something all museums should aim for.9 while larger museums have done well, smaller ones have not been as successful.10 much of past knowledge is stored in small museums, whose importance in preserving cultural heritage should not be underestimated.11 they sometimes add far more to social capital than larger national ones.12 though the need for museum collections online is recognized, there are limitations. if it was simple, every museum would be online.13 however, most small museums are not online.14 their collections remain digitally inaccessible to future generations.15 oberoi and arnold have gone so far as to maintain that information absent from the internet can be regarded as nonexistent. 16 on the other hand, in rare cases where small museums have their collections online, they target human consumers.17 the information is stored in isolated data silos incompatible with automatic processing. the challenge is to make collections discoverable via online search engines and metadata aggregators.18 the issue appears to have been ongoing for many years as gergatsoulis and lilis maintain that the web lacks semantic information and it has proved challenging to process such a massive set of interconnected data as mentioned 18 years ago.19 clearly, online collections must be understood and used efficiently both by humans and machines, because machine-consumable content will end up in human-consumable content.20 the current state and challenges small museums find it difficult to publish their collections online. most large museums have undergone a digital transformation, but few small ones have.21 the museum survey by tongue in 2017 showed that the number of museums planning to publish their collections online decreased from 40 percent in 2016 to 24 percent in 2017, although only 8 percent had already gone online by 2018.22 the survey in 2020 by network of european museum organisations (nemo) on digitization in european museums shows that an average of 20 percent of museum collections in europe as a whole are online, and the median is 10 percent. surprisingly, 43 percent are digitized but not online, meaning the public has access to less than half of the existing digital items.23 information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 3 avgousti and papaioannou a report by flynn in 2018 reveals that most historical society collections are not accessible online.24 according to honeysett and falkowski, the majority of museums in their survey in the us have less than 10 percent of their collections online.25 according to a survey by axiell in 2017, only 21 percent of museums have a complete collection online, 27 percent more than half, 38 percent percent less than half, and 14 percent percent have no collections online.26 in 2020 beaudoin pointed out that approximately 32 percent of us art museums with holdings provide online collection systems that are openly available to the public, while 13 percent do not even have an institutional website.27 avgousti, papaioannou, and gouveia indicated that even if small museums manage to give online access to their collections, they are often stored in isolated data silos incompatible with automatic processing.28 the museum survey by vernon systems in 2016 showed that 82 percent of museums do not use any machine-consumable standards.29 furthermore, only 11.9 percent use dublin core as a metadata standard, 3.6 percent darwin core, 1.2 percent ead and 8.3 percent other. further, the existence of individual collections online, maintained by different organizations, brings challenges to the discoverability, sharing, and reuse of resources .30 metadata aggregation is a frequently utilized strategy in which centralized organizations, such as europeana,31 collect associated metadata to make resources more discoverable and usable. why do we witness such low levels of online publishing in small museums? and why are online collections not in a format that is searchable and easy to find? according to the relevant literature, small museums lack resources and skilled staff to move to the digital age. current obstacles a key obstacle in the digitization of small museum collections is insufficient resources. large cultural heritage institutions have much greater access to funds.32 according to klimper, while the internet has had a tremendous impact on the democratization of european culture, insufficient financial resources remains a significant challenge for small museums.33 irina oberlander from the institute of cultural memory has pointed out that small and medium-sized museums with limited budgets are digital age victims.34 laine-zamojska stressed that small museums, which are often entirely run by volunteers, cannot afford to digitize or make their collections available to a wider audience.35 therefore, online access to cultural heritage in these small institutions is minimal. the nemo report in 2020 showed that insufficient staff is another major obstacle for museum digitization and online accessibility.36 small museums are understaffed.37 this is confirmed by gallery systems, who noted that small museums face their own set of collection challenges.38 with smaller team sizes and limited staff hours, it is difficult to operate. the museum survey by tongue in 2017 showed that 73 percent of museums did not have dedicated staff to manage online collections.39 this means that collection management is given to staff who already have a full job description. avgousti, papaioannou, and gouveia pointed out that museums do not usually hire experts to plan, develop, deploy, and maintain a digital collection, but delegate the task to museum staff who are often limited in technological skills,40 while wigodner and kearney mentioned that small museums typically have fewer (if any) employees devoted to web publishing.41 fewer employees often means a lack of skilled personnel. in the aforementioned survey, no museum with fewer than 50 staff members reported employing a computer expert.42 additionally, honeysett and falkowski mention that two-thirds of museums have one or no it personnel.43 in information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 4 avgousti and papaioannou addition, the same concern has been observed in small university libraries, whereby 67 percent did not have an it expert.44 further, small museums do not have suitable technology, and in many cases, the staff is not technologically adept.45 additionally, klimper affirms that the internet promise of providing access to european culture is hampered by a lack of technological skills.46 considerable expertise in semantic web technologies is needed to expose machine-consumable content to the “web of data.”47 finally, in-depth knowledge of modeling, along with programming skills, are also essential needs. complexity of technology and metadata issues the nemo report in 2020 showed that less than 20 percent of museum collections are online.48 as already mentioned, this may be attributed and related to the prerequisites of online collections as they include complex technology or the need for online platforms. additionally, avgousti, papaioannou, and gouveia pointed out that small museums do not have suitable technologies.49 within the discussion on the semantic web (also known as web 3.0, the world wide web’s extensions that make internet data machine-readable via applying standards), corlosquet stated that one of the significant challenges is getting semantic web data annotations to the end-user applications. if this is achieved, there will be faster adoption of the web of data. moreover, while content management systems (cms) significantly aid the production of online content by end users, the problem of allowing the user to produce semantic web content remains elusive.50 further, velios discusses the problem of understanding semantic web concepts concerning complex setups.51 such setups may be bewildering for those humanities scholars without a technical background. he mentions that the semantic web does not offer the necessary tools to accommodate data easily. vavliakis, karagiannis, and mitkas postulate that even for the mainstream use of the semantic web in the cultural heritage community, easily operated tools are also required.52 cultural heritage institutions are encouraged to start processing and publishing content with semantic technologies. still, the tools which can undertake such a considerable task continue to lack user friendly features. daradimos, vassilakis, and katifori claim that small museums use content management systems to publish their collections online.53 however, using a general-purpose cms (e.g., drupal) comes with great difficulty, primarily due to the lack of technical information such as dublin core fields, as nontechnical staff cannot be expected to know how to install and configure appropriate modules within drupal to enable the entry and publication of this metadata.54 however, there has been little development of the current cmss regarding user-friendly tools targeting the implementation of semantic markup annotations. the integration of cms into semantic web technologies will increase cultural heritage knowledge dissemination remarkably. further, the absence of robust and easily usable tools is considered a central challenge that continues to pose obstacles concerning the rapid adoption of semantic web and linked data.55 antoniou and van harmelen explain that the semantic web’s adoption relies on developing new and straightforward tools.56 the semantic web is also being based on the adoption of the existing technology rather than on new scientific solutions. modern and easy-to-use tools will facilitate the information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 5 avgousti and papaioannou semantic web’s adoption compared with what is available in the current conjuncture. however, only a small number of institutions use semantic technologies. tim berners-lee, the brains behind the semantic web, points out that the machine-readable web is always farther off compared to the human-readable web.57 in cases of large and well-funded organizations or museums like the bbc or the british museum, it is possible to work with semantic web technologies. on the other hand, small museums will have difficulties with the semantic web’s smooth implementation.58 it is pivotal to emphasize that challenges related to the implementation of machine-consumable content by museums rely heavily on adopting existing technology rather than on scientific approval. as antoniou and van harmelen have underlined, the most significant needs are observed in the areas of easily accessible tools that are approaching nontechnical communities. the most significant technological progress will lead to a more advanced semantic web compared to what can be achieved today.59 methodology data collection methods interviews are regularly used in qualitative research for data collection.60 structured interviews lead to more specific answers, usually in a controlled environment. in unstructured interviews, there are no set-in-advance questions, and the interview can be very broad, open, and exploratory. semistructured interviews fall in the middle, as they allow both a few specific questions to be addressed and space for extra information via deviating from the set questions. this is the main reason why they are one of the most popular and widely used methods of data collection.61 the interview type selected depends on the questions to be asked and the research method. the current research aims to collect a comprehensive understanding of a problem. therefore, semistructured interviews were the ideal tool, and an interview guide containing open-ended questions was developed. selection of the sample the researcher selected museums based on nonrandom criteria. techniques for nonprobability sampling methods are often suitable for qualitative research. nonprobability sampling’s aim is not to test a hypothesis about a large population but to establish an initial understanding of a small community or a population under research. the current research targets small museums in cyprus. therefore, a nonprobability sampling method was used to select small museums. the small museums contacted were not always responsive. however, we managed to conduct interviews with six small museums in cyprus using the snowball sampling method, where the researcher asked the interviewee to refer other people for conducting future interviews. sample size in the current study, the sample population is homogeneous, meaning the population is related to small museums in cyprus. when the population is homogenous the sample size should be at least 4 to 12 cases. in cases of heterogeneous samples, for example in small museums from around the world, the sample size must be at least 12 to 30 cases. in more complex cases such as ethnographic or grounded theory, the sample size must be larger. information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 6 avgousti and papaioannou in our case, we started with two cases and continued until data saturation was achieved, the point in the research when no new information is discovered in data analysis.62 cyprus has 34 museums of which 10 are small (for this survey, defined has having one full-time and fewer than five total employees). we interviewed six of the 10 small museums and reached data saturation after interviewing the first four. conducting the interviews in preparation for the interviews, we contacted the interviewees by phone and email, informing them about the interview. information on the size of the staff was gathered by contacting the museum. while ten museums met the definition of small, only six agreed to participate in the research. first, a pilot test was conducted on two interviewees to identify any problems with the interview guide. based on this pilot test, we made changes and corrected mistakes. due to the covid-19 pandemic, interviews were conducted via internet-based technologies, mostly zoom, a video telephony software program, chosen because of its ability to record video. the interview length was about 20–25 minutes, and all participants had the option to choose greek or english as the interview language. due to the pandemic and logistic challenges, it took about six months to identify subjects and conduct the interviews. results this section discusses the empirical results extracted from the interview summaries. interviews were conducted in greek (both authors are native speakers of greek) and translated to english by the authors. under the major headings of our research subject, we present our findings concerning our research question. the current state of collections online our results indicate that most small museums in cyprus do not have an online presence. two of the six museums (4 and 5) do not have a website. the ones that do have websites created but not updated or supported for more than 15 years, and which therefore need replacement. here are two representative comments: “the museum has an old and simple website” (respondent 1); “[we have] a very old website that needs to be changed soon” (respondent 3). the two museums that do not have a website, use/have used social media: “the museum uses facebook and instagram” (respondent 4); “[we] used to have a facebook page” (respondent 5). we discovered that five of the six museums do not have their collections online: “the museum does not have any of its collections online” (respondent 1); “no online collections” (respondent 4); “we do not have any collections online” (respondent 5). further, we learned that none of the museums use machine-consumable standards to achieve wider interoperability on the web: “the online collections are only in a human-readable format” (respondent 2); “we do not use any machine-readable” (respondent 3). however, museums understand the need and benefits of such solutions: “our goal is to have the online collection understandable by machines and share metadata online” (respondent 2). information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 7 avgousti and papaioannou we noticed that all museums are willing to give online access to their collections, complete or partial, and agree that the primary goal is to disseminate information: “the primary goal is to give access to museum collections for general use” (respondent 1); “to put it another way, to communicate information, knowledge to scholars and the general public” (respondent 2); “to reach as many people as possible and spread those collections online to a variety of audiences” (respondent 3); “the main reason that online collections exist is that it is the tool to reach more people and disseminate those collections online to diverse audiences, researchers, and the public alike, in other words to disseminate knowledge” (respondent 4); “to disseminate knowledge and information to more people such as students and researchers and the general public” (respondent 5). museums also view online collections as a marketing tool that can bring more people to the museum’s physical space: “[online collections] can work as a marketing tool, people that can view our collections online may visit the museum physical space” (respondent 4); “the main goal is to be found” (respondent 5); “tourists coming to cyprus can use the system and find out about our collections and the museum” (respondent 6). clearly, museums are eager to give online access to their collections. the goal is to disseminate information and attract more people to their physical premises. when asked about the goals of publishing machine-consumable content online, findability was most significant: “nowadays, people are using search engines to find the information they are looking for. and since the information is not in a machine-readable format and understandable by search engines, it creates difficulties to be located online” (respondent 1); “[the goal is] to make the collections more findable” (respondent 2); “… to be easily findable by search engines on the internet” (respondent 3); “[to] increase wider findability of the collections over the web” (respondent 6). additionally, we discovered that some museums are not aware of the existence of machinereadable formats: “i am not aware of machine-readable data” (respondent 4); “the museum is not aware of any machine-readable standards for wider web interoperability” (respondent 5). it is evident that findability is the main goal in online content. but it is also clear that some museums are not aware of the existence of machine-readable standards and such technologies. the current challenges of collections online insufficient resources and the cost of existing solutions our study shows that museums’ insufficient resources and the cost of existing solutions are the main obstacles in having their collections online. here are five representative comments: “lack of money” (respondent 1); “we got offers from different companies; however, the costs of existing solutions were well above our budget and possibilities” (respondent 2); “the main obstacle related to giving online access to the museum collections is the cost … outsourcing this kind of work costs a lot of money that the museum does not have” (respondent 4); “of course is the cost” (respondent 5). insufficient staff (time) and skilled staff (know-how) according to our findings, staff limitations are another obstacle small museums face in providing online access to their collections: “the existing staff has so many other responsibilities mostly related to research and museum daily functions” (respondent 1); “populating all the material to a new system requires a lot of time and staff that the museum does not have” (respondent 2); “the museum’s limited staff” (respondent 4); “the limited staff of the museums is a problem” (respondent 6). information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 8 avgousti and papaioannou further, interviewees shared that the lack of know-how is another obstacle to digitizing and making accessible museum collections online: “we do not have the technical knowledge. of all of the staff members, no one has technical knowledge … this means that we must hire a person that has this kind of knowledge” (respondent 1); “we do not have a dedicated staff to work specifically for this function” (respondent 6). complexity of technology (existing systems) according to our research, the existing technological complexity is another major problem: “the lack of easy-to-use tools that we can use at the museum [is a problem]” (respondent 1); “creating a content model selecting all necessary fields is a very complex and time-consuming process” (respondent 2); “we need tools that are user-friendly, easy to use with nontechnical complexity without requiring a too specialized technical know-how” (respondent 3); “the technological complexity that is involved” (respondent 5); “hosting your own online collections due to the maintenance and technical knowledge is another issue that small museums are facing” (respondent 6). insufficient infrastructure our research revealed the lack of technological infrastructure was an obstacle: “the lack of infrastructures … we cannot work with this kind of old infrastructure … we cannot work with a computer that is 20 years old, this is impossible … [we have] only one old computer that is connected to the internet” (respondent 1); “primary challenges related to technological infrastructure” (respondent 3); “the existing infrastructure of the museum, we have old computers” (respondent 4); “hosting your own online collections due to the maintenance and technical knowledge is another issue that small museums are facing in cyprus. this is why we use external platforms” (respondent 6). not machine consumable the complexity of technology was highlighted as the biggest challenge in publishing collections online in machine-consumable formats: “easy-to-use solutions” (respondent 1); “selection of the appropriate technology, there are so many standards for machine-readable data making the selection process extremely hard” (respondent 2); “the complexity of technology is the main obstacle” (respondent 3); “if the system we use can automatically create machine-consumable content this will help” (respondent 4); “the platform that publishes the collection humanconsumable content can at the same time publish in machine-understandable content will solve the problem” (respondent 6). for some, machine consumption is not a priority: “it is not a first priority of the museum” (respondent 5); “the museum is not familiar with machine publishing” (respondent 6). the complexity of technology and the lack of easy-to-use tools are among the biggest obstacles to publishing machine-consumable content. discussion and conclusions existing online collections and/or museum resources should be researched further as they may not be completely digitized and accessible to different audiences online. with one-third of small museums in cyprus providing access to their collections online, there are many opportunities to help small museums to give access to their collections to benefit information knowledge democratization. information technology and libraries march 2023 the current state and challenges in democratizing small museums’ collections online 9 avgousti and papaioannou we discovered that the lack of resources and infrastructure are two significant challenges small museums in cyprus face in providing online access to their collections. our results show no museum partners with national institutions, such as universities or academic research centers. we assert that this collaboration can reduce costs and eliminate the need for infrastructure. at the same time, institutions, such as universities, usually have the technological know-how and can provide museums with new tools, free and open-source systems that focus on cypriot small museum needs. such tools, which can be found in our research, will help museums to drastically reduce the cost that is involved in buying such systems. moreover, we found that the lack of staff (time) is another challenge that prevents museums from having their collections online. we believe that developing new tools that can accelerate the process of generating, administering, maintaining, and uploading museum collections online will alleviate staff time. our research also uncovered that small museums in cyprus do not work with volunteers, as they have no time and resources to find and then train volunteers to museum work; we suggest museums must consider these options concerning the lack of staff (time). additionally, we learned that museums lack specialized staff (know-how), another significant challenge that blocks museums from democratizing their online collections. we anticipate that developing technology that requires less technical expertise will benefit small museums that do not have specialized staff (e.g., developers and information technology specialists). further, help from external bodies such as universities may help. on the other hand, there are platforms available that do not need specialized technical knowledge. however, we discovered that the complexity of existing technology impedes museum collections online. we hope that creating less complex technology will enable museums to use and publish their collections online in human and machine consumable formats. further, training of existing staff in new technologies is needed. to sum up, small museums in cyprus and the world need to invest in democratizing their collections online via digitizing, describing, and making their objects and collections available online. simple and turnkey solutions for publishing and describing digitized objects are required. there is a will; we keep researching towards finding the most suitable case-oriented and affordable ways. acknowledgments many thanks to all the interviewees from small museums in cyprus that opened their doors to our research. for ethical considerations, we keep institutions and interviewees anonymous. information technology and libraries march 2023 the current state and

searching library resources, including a comparison of the method with a tabbed search interface. it then describes a usability study conducted by the franklin university library in which 27 students searched for an article, an ebook, and a journal on two websites: one using a bento box and one using the ebsco discovery service (eds). screen recordings of the searches were reviewed to see what actions users took while looking for information on each site, as well as how long the searches took. students also filled out questionnaires to indicate what they thought of each type of search. overall students found more items on the bento-box site, and indicated a slight preference for the bento-box search over eds. the bento-box site also provided quicker results than the eds site. as a result, the franklin university library decided to implement bento-box searching on its website. introduction “one page, one search box, results from as many library-resource types as possible.”1 in 2018, the franklin university library redesigned its website to provide users with a more modern interface that more closely matched franklin university’s website. the library also wanted to improve the site’s usability and make it easier for students to find information. to determine how to best improve the user experience, library staff members held a number of meetings to discuss the new site’s layout and contents. because “students almost always resort[] to searching via web site search boxes rather than navigating through the web site by browsing,” a crucial decision involved what search results the redesigned library website would provide. 2 as a result of these discussions, the franklin university library’s initial website redesign included a persistent search bar in the upper left of each page which searched the library’s website, as well as a prominent tabbed search bar on the library’s homepage (see figure 1). the homepage search bar provided a default tab that used ebsco discovery service (eds) to search the library resources cataloged in eds (most of the library’s databases and catalog) and a second tab which used ebsco’s journal finder to look for e-journals. once our new website went live, feedback from patrons demonstrated that the persistent website search bar caused confusion among users who expected it to search the library’s databases rather than the library’s website. we also found the “search journals” tab on the homepage unnecessary. as a result, we removed both the persistent search bar and the journals tab. after these changes, the main search option provided to library users was the eds search bar on the library’s homepage, although some interior pages of the library’s website provided a search bar related to that page (such as an option to search the catalog on the catalog page). although eds searches mainly for articles and books, it “may overlook user needs for other types of library mailto:marc.jaffy@franklin.edu information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 2 resources or services.”3 this is a problem because “library users increasingly perceive the discovery interface as a portal to all of the library’s resources.”4 due to dissatisfaction with the eds search, the library decided to look for alternatives. one alternative which “[a] number of libraries have turned to [is] the bento-based approach to discovery and display.”5 figure 1. redesigned franklin university library website with two search boxes on the homepage. the circled search box in the upper left was initially persistent across the entire site. to determine whether the bento-box search format would serve our users better than eds, the library designed and conducted a usability study comparing eds and bento-box searches. by comparing user search behavior and results for each search method, as well as user opinion regarding these different methods of searching library websites, the library hoped to gain a clearer understanding of how its users interact with search boxes on the library’s website and— most importantly—which search method would best serve its users. the remainder of this article sets forth the results of that trial. after explaining what bento-box search is, as well as reasons a library might want to use bento-box search results, it reports on a usability study the franklin university library conducted by discussing both the observations of screen recordings demonstrating user search behavior and responses to questionnaires. information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 3 bento-box library search what is bento-box search? the term “bento box” is based on “japanese cuisine where different parts of a meal are compartmentalized in aesthetically pleasing ways.”6 instead of compartmentalizing food, a bentobox search results page compartmentalizes search results from a variety of different resources on a single page. the user sees a single search box which gives “side-by-side results from multiple library search tools, e.g., library catalog, article index, institutional repository, website, libgu ides, etc.”7 a bento-box search provides results based on searches of individual library resources. this is important because of the difficulty of providing a single search that includes combined results from all resources: “the nature of library content and current technology makes it difficult to create usable ‘blended’ results; catalog materials may crowd out books or vice versa.” 8 bento-box results avoid this problem by “provid[ing] these resources on equal footing, leveraging the ranking algorithms internal to each resource’s individual search interface.” 9 as a result, the bento box gives libraries “the best cost/benefit way to improve article search relatively quickly with relatively large user benefit.”10 figure 2, the university of michigan’s bento-box results page, illustrates how a bento box provides search results from a variety of resources in visually discrete boxes. this is done behind the scenes by using separate searches to query the individual resources, as demonstrated by figure 3, the architecture of wayne state university’s bento-box search. benefits of a bento-box search results page wayne state university’s switch to a bento box “resulted in increased access to resources.”11 a bento box can increase access to resources both because it makes library search easier for users and because it provides results in a format that makes it easier for users to find information. simplified search when deciding what type of search to provide on the library website, the main consideration involves what users expect when searching. student experiences with internet search engines have influenced their expectations for library search, which leads them to “approach library search interfaces as if they were google.”12 what do users like about google? “one of the main reasons that users are satisfied with google is its simple user interface.”13 based on their experience with google and other search engines, library users “expect easy searching” that provides “one-step immediate access to the full text of library resources.”14 bento-box results let libraries meet these expectations by presenting users with a simple interface that permits easy searching and “returns results across many library sources.”15 additionally, bento-box results “can integrate library website results, allowing users to type things like ‘how do i renew a book’ into a single search box and get meaningful results.”16 as a result, adopting a bento-box search results page can permit a library to satisfy user search expectations. the bento-box format will provide users the information they seek whether they are looking for an article, a book, or information about the library. information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 4 figure 2. university of michigan library’s bento-box results. information

hukill, “one-to-many: building a single-search interface for disparate resources,” in k. varnum (ed.) exploring discovery: the front door to your library’s licensed and digitized content (chicago: ala editions, 2016): 147. better presentation of results bento-box results can help alleviate user confusion because “format types [are] more evident: novice users, such as undergraduates, may not have a good understanding of the difference between books, journals, and articles.”17 the bento-box presentation makes it easier for users to find information since “results from different sources are returned to visually discrete boxes” 18 on a single page. this presentation of grouped results benefits library users because “[b]y presenting search results in separate streams, users can more easily navigate to what they need.”19 when the princeton university library implemented a bento-box results page (termed all search), it found that “most users praised the new all search for its ease of use and also for the ‘bento-box’ approach of grouping results by category. they felt that this clarified the results they were seeing and made it easier for them to pursue different avenues of inquiry.”20 information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 6 comparison with tabbed searching one alternative to the bento box is to offer users a tabbed search box which lets users select a specific resource to search by selecting a tab on the search bar. before the 2018 redesign, the franklin university library’s website provided users with a tabbed search box, as shown in figure 4. our redesigned website reduced the number of tabs from four to two, but we ultimately removed tabbed search from our website because we did not find it effective. figure 4. previous franklin university library website with tabbed search box. tabbed search requires users to decide which tab to use. when the franklin university library provided a tabbed search box we found that users had difficulty identifying which tab they should use. in addition to causing user confusion over which tab to use for their search, because each search tab only searches a portion of library resources, tabbed searching “misses a wide swath of available information and resources [which] will make that missing information practically invisible.”21 another problem with tabbed search is that it requires a library to designate one of the tabs as a default search. this can lessen the chances that users will search (or use) resources in the nondefault tab(s) because library users “tend to favor the most prominent search option.”22 lown, sierra, and boyer cited a study which found that the default option was used 60.5 percent of the time in a tabbed interface, and reported that on the north carolina state university website the default tab was used 73.7 percent of the time.23 tabbed search does not meet library user needs because it is “inconsistent and confusing.”24 when wayne state university switched from tabbed searching to a bento box “many library resources that were previously hidden from search and discovery on the main library website were, for the first time, exposed to all searches, for all users . . . [which] resulted in increased use and awareness of these resources.”25 information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 7 design considerations bento-box results pages are highly customizable. a 2017 review of 38 academic libraries using bento-box search found “much variation in the implementation.”26 a bento-box results page needs to balance providing necessary information with displaying results in a way that is not too overwhelming—or too cluttered. the university of michigan analyzed usage of its bento-box results page and redesigned it to improve how it presented results to library users by displaying “[f]ewer results . . . in each section—with a more prominent ‘see all’ link—than in the original design.”27 given user expectations and the challenges previously discussed, libraries must design the results to “maximize the exposure of [their] collection[s] and services, in the most appropriate precedence, while preventing cognitive overload.”28 a cluttered results page, with a lack of distinction between categories, will make it difficult for users to find information and will cause confusion rather than ease it. another concern with a bento-box results page occurs when some of the result boxes “end up ‘below the fold,’ meaning users will need to scroll down to see them. this creates the same problem as a tabbed search box—users don’t see results from all library sources.”29 because users are less likely to see below the fold search results, the bento-box results page needs to prioritize category locations so that the more important results are above the fold (which requires the library to determine the relative importance of search result categories). user experience study at franklin university the trial design during franklin university’s fall 2018 and spring 2019 welcome weeks, in addition to providing students with information about the library’s services, staff at the library’s information table asked students to participate in a trial to help determine whether adopting a bento-box results page would benefit our users. participants were offered a franklin university coffee mug as an incentive. the trial asked participants to look for information on two different library websites: one using eds (franklin university library) and one using a bento box (wayne state university library). we set up two laptops for participants to use and made screen recordings of the participants’ actions during their searches for later viewing and analysis. after they finished the tasks we asked participants to fill out a questionnaire (reproduced in appendix a), which had three background questions and six questions about their experience/thoughts relating to the tasks. to decide what information to ask participants to look for, we reviewed library websites that used bento boxes to see what categories they searched. we compared those categories to the types of information available on our library’s website. although we identified a number of possible categories, we decided to limit the trial to three tasks because we did not want to overburden participants. based on our experience working with students, we decided the three categories we were most interested in investigating: articles, books, and journals. to see how users searched for items in these categories we asked participants to complete the following three tasks on each website: information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 8 1. find an article available through the library on the topic “criminal justice.” 2. find the ebook lean six sigma for leaders by martin brenig-jones and jo dowdall. 3. find the electronic journal business today. participants thirty-four people participated in the trial. however, not all of the participants completed all of the tasks on each library’s website. we discarded the results from participants who did not attempt at least two tasks on each library’s website. removing those who did not complete at least two tasks on each site left 27 participants (“adjusted” results). unless otherwise noted, the data discussed below refers to the adjusted results. the trial was open to students, faculty, and staff. eleven participants took the trial in fall 2018 and 16 participants took it in spring 2019. most of the participants were undergraduates (21), with some graduate students (6). no doctoral students, faculty, or staff-only participated. (one staff member participated and completed a questionnaire but did not perform enough tasks for their results to be included.) results we watched the screen recordings to time how long it took students to complete the three tasks on each library’s website. however, if a student flipped between the sites while searching instead of first completing all three searches on one site we did not time the results. we also observed what students did while searching to gain an understanding of how they searched for information. overall, students spent less time searching on the site using the bento box (wayne state university library) than they did on the franklin university library site: • students spent an average of 2 minutes, 35 seconds to complete the tasks on the wayne state site compared to 3 minutes, 28 seconds on franklin’s. • twelve students finished their searches quicker on wayne state’s site, while six had quicker results from franklin’s. how students searched for information the screen recordings showed that students looking for information often went to parts of the library websites which did not contain the content they sought. frequently, they would search whatever part of the site they were on—even if it did not contain the content they needed. on the wayne state site, when a student used an interior search bar the bento box provided results from a wide range of library resources. a search on the journals page would give results for journals, books, articles, and more—even if the page they were on did not contain the resource they needed to find. by contrast, any interior search box found on the franklin university page would only provide results for whatever portion of the library’s resources that search box accessed: a search on the journals page would only provide journal results, a search on the catalog page would only provide catalog results, etc. student action after the initial search demonstrates the need for interior search boxes which can search the library’s entire site. twelve of 27 students on each site (although not the same 12 students) followed up a search by using a search bar they found on their results page without returning to the homepage to use the main search bar. students did this even when the page they were on did not relate to the content they were looking for. information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 9 for library users, the division between the content of the library’s website and the content provided by the library “’is not obvious and makes no real sense.’”30 the screen recordings of student behavior when searching for content on library websites demonstrated that students also could not distinguish between different areas within the library’s website. search for articles the first task asked students to find an article on criminal justice. because it was the first task on the list, most students started with this search. students had more success finding the article on franklin’s site than on wayne state’s site (18 to 14). although only 14 students were credited with finding the article on wayne state’s site, several students actually reached the bento-box page which included a category for article results. however, they did not realize that they had found the article and selected an ebook or database instead. search for ebooks the second task asked students to find the ebook lean six sigma for leaders by martin brenigjones and jo dowdall. students had more success finding this book on the bento-box site. twenty students found the book using the wayne state library’s bento-box search, compared to ten who found the book on the franklin university library’s site. many students, in searching for the ebook, typed their search on the results page from the previous search. on the wayne state university library’s site, this led to a bento-box results page which included the book. on franklin university library’s site, the results were more complex. between fall 2018 and spring 2019, our ebsco eds custom catalog was not renewed, which resulted in the search results for the ebook no longer displaying in eds. [this non-renewal was not intentional.] as a result, in fall 2018, the ebook that students looked for appeared in eds search results (on both the franklin university library’s main search bar and interior ebsco search boxes); however, in spring 2019 it did not. to see what effect this had, we looked at the more limited search results from the fall 2018 trial when an eds search on franklin university library’s site would successfully find the book. even then, students had more success finding the book on the bento-box site: 9 students successfully found the book on wayne state’s site, compared to 7 on franklin university’s site. some students on franklin university library’s site tried, unsuccessfully, to identify the proper page of the library’s site to find “books.” instead of the catalog page, they went to a page labeled “textbooks” which helped students locate course reserves. because there was no search option for the entire site on that page, those students did not successfully find the ebook. search for journals the third task asked students to look for the journal business today. as with the ebook search, students had more success finding the journal on the bento-box site: 19 students found the journal on wayne state library’s site compared to 10 on franklin university library’s site. students searched for the journal in a similar manner to the way they searched for the ebook. many just put the journal title in the search bar on the page they were on—if that search bar on franklin university library’s site provided access to the journal, they would find it with their information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 10 search. but if they were on a page which did not have a search which included the journal as a result, they would not. the journal search on the wayne state university library’s site demonstrated the “below th e fold” problem discussed above because the bento-box result for “journals” was below the fold. as a result, at least one student properly searched for the journal, but did not find it because the result was not visible on the screen and they did not scroll down. questionnaires we asked students a series of questions about their experience searching for information on the two library websites (see appendix a for the questionnaire and appendix b for the results). slightly more students preferred the wayne state library’s site (14) to franklin university’s (12). however, five of the users who preferred franklin university’s site referenced their familiarity with that site. four of these users specifically referenced their familiarity with the franklin university library site in response to a question asking “[w]hy did you prefer the type of search you picked,” while one referenced their familiarity with franklin university library’s site in response to a question asking whether there was “anything else you’d like to tell us.” the questionnaire also asked students why they preferred one site to the other and what they liked and disliked about each site. preference: franklin university library as mentioned above, many of the comments from those who indicated a preference for the franklin university library site indicated the preference was due to familiarity: • “might be because i am a bit used to it, i just found it easier to navigate.” • “because it’s the one i am familiar with.” • “because i'm familiar with it.” • “i liked both. both easy to use. familiar with franklin's.” other comments favored franklin university library’s overall website design (as opposed to search): • “the website is cleaner. easier to use.” • “easier to navigate.” some of the comments did indicate a preference for the search technique: • “one search bar to search all types. seemed to include more in search results.” • “it easy to search and straight forward.” • “access to research was quicker on the franklin website. also, i felt like there was more research material available.” preference: wayne state university library those who preferred the wayne state search did so more based on the search technique than did those who preferred franklin: • “simple and the search was in one spot.” information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 11 • “one search bar that pulled from the [catalog].” • “because you can type in exactly what you were looking for and it comes up.” others appreciated the way search results were displayed: • “their search system organizes the result by type of information, whereas franklin's website makes you search for the type of material information before displaying the results.” • “better layout breaks articles, journals, etc. into separate columns.” • “wayne had each section (book, e-journal, article) separately which was easier to find.” • “the layout.” still others just found the wayne state library search easier to use: • “it is more visual and easy to find and easy to use.” • “it presented the information in an easy way to find.” • “easy—all in one.” what search results do library users want? we asked participants to rank which results they would like to see displayed when searching on the library’s site. while most applied a numerical ranking, some just circled items. all questionnaire responses were included when compiling these rankings, including rankings from those who did not complete at least two tasks on each website, because user preferences about what search results they want are valid even if they did not perform the required tasks on each library’s website. we converted numerical rankings so that the first choice received six points, the second choice five points, etc. of the 34 participants who answered this question, 24 provided rankings and ten circled items without indicating how they ranked those items. where participants circled items, we converted their responses to a numerical equivalent based on how many answers they circled. if they only circled one, it was treated as the first choice, and given 6 points. if they circled more than one, we combined the numerical value of the answers and each answer received the average value. (for example, if two answers were circled, they were treated as a first and second choice, and each circled answer was given a score of 5.5.) the responses indicate students most wanted library search to provide results for articles and journals, followed by databases and ebooks: • articles: 144 • journals: 125 • databases: 112 • books/ebooks: 111 • research guides: 69.5 • library site: 63.5 mischo, norman, and schlembach reported actual usage of the university of illinois’ bento-box results page by category between 2015 and 2017. how do the categories our users indicated they information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 12 would like to see on a bento-box results page compare with the actual use of bento-box results at the university of illinois? at the university of illinois, 56.1 percent of click-throughs were for articles (franklin university students’ first choice), while 33.6 percent were for book and online catalog content (our students’ fourth choice).31 databases, our students’ third choice, were not a listed category, while journals (franklin university students’ second choice) were only the fifth-most used resource (and the percentage of click-throughs was low, at only 3.6 percent).32 limitations there were a few issues with the study which should be kept in mind when evaluating the results. number of participants thirty-four individuals participated in the trial. after removing results from participants who failed to complete a sufficient number of tasks, only 27 participants remained. while this number is small, it does provide information on what students think and, more importantly, how they act when searching for various types of information on the library’s website. examples of library user experience testing based on similar numbers include: • the university of kansas library conducted “usability testing of our primo discovery interface on basic library searching scenarios for undergraduate and graduate students” and reported results from 27 users.33 • the university of southern mississippi library conducted usability testing of 24 users (“six participants from each of the following library user groups: undergraduate students, graduate students, faculty, and library employees”) to evaluate and modify their website.34 • syracuse university conducted usability testing on “ten students . . . and eighteen library staff members.”35 familiarity with franklin university library website student familiarity with the franklin university library website affected student opinion. of 12 students in the adjusted results who preferred franklin university library’s site, 5 (41.7 percent) gave an answer indicating that familiarity was a factor in their preference. when considering all the questionnaires (including those from participants who were not included in the adjusted results), 7 out of 17 users (41.2 percent) who preferred franklin university library’s site gave an answer referencing familiarity. as a result, opinion may have been skewed in favor of franklin university, despite wayne state being slightly favored overall. a good illustration of this problem is the response from a student who the screen recording showed did not even attempt any of the tasks on the franklin university library website but indicated a preference for the franklin university library site because it’s “easy to use.” conclusion as a result of the user experience study, the franklin university library decided that providing bento-box search results would benefit our library’s users. the trial showed that students required less time to conduct their searches using wayne state’s bento-box search and found more items successfully on wayne state’s site. information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 13 the lack of student distinction between different types of library content, along with the likelihood of their entering a search in whatever search box they see on a page further supports providing bento-box results. adopting a bento-box results page will permit the library to provide search boxes on interior pages which permit students to search for materials site-wide. the bento box will let students search for content anywhere on the library’s web site without requiring them to first figure out what type of library resource they are looking for and then find the correct section of the library’s website. additionally, the ebook search issue previously discussed demonstrates the benefits of switching to a bento box. the disappearance of ebook search results from the eds listing would not have mattered with a bento-box style search because the bento box would have displayed a box for catalog results. comments from two of the students who preferred the wayne state library website demonstrate the benefits of a bento-box format. the bento-box search meant that wayne state’s site is “simple and the search was in one spot.” it also helps students because “[wayne state’s] search system organizes the result by type of information, whereas franklin's website makes you search for the type of material information before displaying the results.” information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 14 appendix a: questionnaire about this study the franklin university library is studying how users search for, and find, information on library websites. the purpose of this study is to ask library users (and potential library users) to search for information on two different library websites and give their opinion on their search experience. you are asked to be a participant as a member of the franklin university community who is a library user, or a potential library user. we hope to have between 20 and 50 people participate in this study. if you agree to participate in this study, you will be asked to look for information to find four different resources on two library websites (franklin university’s website and wayne state university’s website). you will only be asked to find the information, not to access the information. you will then be asked to fill out a questionnaire providing demographic information and your opinion about library search. as part of this study, your search activity on the websites may be recorded by screen recording software. your participation in this study is anticipated to take about 15 minutes. there are no known risks to participation in the study. the benefits of participation include helping the library to better serve its users by identifying how users search for information on the library’s website. in return for your participation in this survey, you will receive a franklin university coffee mug. this study is conducted anonymously—no personally identifiable information will be collected. your participation in this survey is voluntary. if you decide to participate, you have the right to refuse to answer any of the questions that make you uncomfortable. you also have the right to withdraw from this study at any time, with no repercussions. this research has been reviewed and approved by the franklin university institutional review board. for questions regarding participants’ rights, you can contact the institutional review board at irb@franklin.edu. information technology and libraries march 2020 bento box user experience study at franklin university | jaffy 15 please answer the following background questions: 1)

implementation of ex libris alma/primo as their library services platform (lsp). the authors conducted a survey of libraries and library consortia in canada and the united states who have implemented or plan to implement alma. the results show that most libraries use both request for information (rfi) and request for proposal (rfp) in their system selection process, but the vendor-offered training is insufficient for effective operation. one-third of the libraries surveyed are considering switching to open-source options for their next automation system. these insights can benefit libraries and library consortia in improving their technological readiness and decision-making processes. introduction with the exponential growth of digital information, libraries have been seeking innovative systems to manage electronic resources and provide collection services. the next-generation integrated library system (ils) should address both current challenges and future demands. with that in mind, new cloud-based commercial products have come into the market in recent years. ex libris alma, oclc worldshare, and innovative sierra are often referred to as library service platforms (lsps) compared to a client-based ils. among these new products, selecting and implementing a new system is no small task. studies show that libraries might overlook the capacity of an ils to accommodate many functions and make a tough choice between sticking with the current vendor or switching to another before investing time and resources to migrate to a completely new system.1 libraries do not make these kinds of decisions in a rational manner, which involves clearly defining the problem, identifying and evaluating potential options, weighing the pros and cons of each option, considering an organization’s values, goals, and preferences, making a choice based on a systematic analysis, and continuously reassessing and adjusting the decision as new information becomes available. as a result, a selected system might not be the best fit for a library’s actual needs.2 library consortia also face a similar challenge, but in a more complex context. for example, sharing cost, level of collaboration, and integration with other library applications can be quite different from a small library to a large research library. additionally, the requirement for security and scalability can vary among consortial members. ninety-four percent of academic libraries migrated their systems to alma in 2018 by joining a consortium.3 at a consortial level, managing a system migration project adds a significant challenge because of the competing, often conflicting desires of constituent institutions. mailto:jiguo@fiu.edu mailto:gordon.xu@njit.edu information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 2 guo and xu budgeting for a migration project needs to be secured before the project takes place. the one-time migration cost has a huge impact on a library’s decision on a new system. lengthy procurement processes mean that it can take a year to communicate requirements, solicit bids, and make a final decision. libraries also wonder if they should acquire such a new system through a consortial deal or on their own. a successful implementation of a new system starts with making a sound choice. the system migration project encompasses various technological and management decisions made by project managers, team leaders, and library administrators. decisions about data cleanup, migration mapping, system configuration, communication, and training can have a tremendous impact on project outcomes, staffing, existing workflows, and job functions and responsibilities. in the meantime, the project itself also provides libraries a great opportunity to improve the existing operational and staffing model and to adjust their strategy to manage technological and organizational change. there are few studies on decision-making of the alma/primo selection, procurement, and migration from the user’s perspective. alma is a cloud-based library management system that helps libraries manage, deliver, and discover digital and physical resources. it offers functionalities such as resource discovery, resource management, resource sharing, and analytics. primo ve is a next-generation library discovery platform that provides users with access to a central index of the library’s collections. it offers a personalized and intuitive search experience, with features such as faceted searching, saved searches, and item recommendations. both alma and primo ve are ex libris products. this case study fills the gap and provides a better understanding of how american and canadian library leaders and administrators make decisions for their libraries and consortia. the pairing of ex libris’s alma and primo products has become a widely accepted next-generation system due to its cloud-based model for managing both electronic and print resources. the findings of this study offer insights and lessons learned to help library leaders and administrators to make better decisions on their future technological change. literature review the growing user demand for electronic resources over the last decade has led libraries to make a rapid digital transformation to manage and deliver online library services. consequently, system providers are hungry to develop the next-generation library systems. organizations have started to adopt cloud computing as their infrastructure. a benefit of cloud computing is that local it staff no longer need to handle hardware failures and software installation. cloud computing streamlines processes and saves time and money. additionally, cloud computing not only enables libraries to deliver resources and services in a network and a library community but also frees libraries from managing technology to focus on collection building, service improvement, and innovation. therefore, libraries have started to migrate their client-based integrated library systems (ils) to cloud-based next-generation systems, often referred as lsps. these lsps can be connected with other web applications, increase collection visibility and accessibility, streamline workflows, reduce duplication of staffing and collections, and create a greener ecosystem for organizations.4 library consortia have been playing vital roles in resource sharing, cooperative purchasing, discovery, user experience, and technical support. many libraries migrate to a shared nextgeneration ils or lsp by joining a consortium. besides sharing common needs, participating information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 3 guo and xu libraries are quite different with respect to their sizes, the kinds and numbers of resources they provide, services, priorities, and staffing. although this could pose some challenges like cost sharing for participating libraries, workflow design, policy, and a collaboration model for libraries, libraries still benefit greatly from the shared catalog and enhanced metadata as well as cooperation on a global level through the product community such as eluna and igelu.5 the selection of a new system is not a small decision. calvert and read pointed out that some libraries turned to “sheep syndrome” of selecting what other libraries have bought due to the lack of software knowledge.6 their study suggested that a request for proposal (rfp) could be a part of the lsp selection process by providing a consistent set of vendor responses with a narrow scope, a formal statement of requirements for benchmarking, and a mechanism for vendors to compete. gallagher advised considering existing contracts, financial resources, and rfps before beginning a system assessment. he indicated that the expiration date of the current ils and opt-out clauses of the existing contract could be the indicators of a go-live date. a price quote including a one-time implementation fee and a cost-benefit analysis of the current ecosystem compared to the vendor offer could provide a helpful document that envisions future library services.7 in addition to an rfp, yang and venable also considered the library automation marketplace and needs of their own library when migrating from sirsidynix symphony to alma/primo.8 gallaway and hines embraced competitive usability techniques to test a set of standard tasks across multiple systems by using focus groups at loyola university new orleans to select a nextgeneration system.9 they also collected anecdotal information and feedback on the system performance of the current library online catalog through a survey of library staff. this evidencebased decision-making process makes system selection in a rational manner. manifold, on the other hand, proposed a principled approach to selecting a new lsp. he believed that system selection was a part of the continuing process of organizational change and needed to involve library staff and users throughout the process. today’s lsp systems can connect almost the entire range of library operations, from resource management and acquisitions to user request fulfillment and the integration of subject guides on research, teaching, and learning a system migration is much more than just a move to a new system; instead, it is a transfer to a new culture. he suggested the acquisitions process must start with educating participants on the features of various systems, methods of vendor assessment, the rules of contract negotiation, communication, and stress management. the success in system selection and implementation should be measured over the life span of the system to guide new decisions along the way.10 in addition to commercial products, some libraries are acquiring open-source software (oss) that enables them to have a greater control over customization. the potential benefits of oss include cost effectiveness, interoperability, user friendliness, reliability, stability, auditability, and customization. koha, evergreen, folio, abcd, winisis, newgenlib, emilda, pmb (phpmybibli) and weblis are examples of oss ils/lsp products on the market.11 when selecting and implementing an oss solution, small libraries such as the paine college colins-callaway library, with a limited budget and small staff, chose a hosted open-source ils (koha) to obtain specific expertise and services at a reasonable price.12 once a system is selected, the implementation process itself can be critical to the perception of overall system success. lovins expressed concern about choosing a project management approach that is schedule-driven over results-driven. he also recommended organizing implementation information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 4 guo and xu activities around the incoming system functionality. for a consortium-wide system migration, a “train-the-trainer” strategy was adopted in the training program, which mostly offers demonstrations instead of instruction to future trainers.13 the program hardly met libraries’ expectation for training. active staff participation in a system migration is key to a project success. banerjee and middleton reported that when library staff owned the migration process, fewer mistakes and greater satisfaction with the new system, as well as quicker troubleshooting of problems that did arise as a result of the migration, were observed.14 avery shared that the god’s bible college libraries did an informal preand post-assessment of library users and staff to gather feedbacks on both legacy and target ils. he recommended conducting a formalized preand post-evaluation of user satisfaction with the ils.15 stewart and morrison observed that acquisitions workflows in a shared alma environment must balance required consortial needs with local policies and procedures. the unmet training needs and the lack of an electronic resources management (erm) module in alma presented challenges for library staff to develop and manage alma workflows. they argued that a two-year project cycle was super ambitious especially if the consortium size and variety of individual libraries involved were large and wide.16 when migrating from horizon to symphony (both are sirsidynix products), king fahd university of petroleum and minerals based in dhahran saudi arabia experienced a delayed implementation. some unmet needs, such as a dramatic shift of workflows, user interface customization, and training support by a system provider or its parent company not matched by a local vendor, became hurdles for this project.17 although a new lsp including alma/primo and oss empowers libraries to create unified workflows across functional modules, this feature requires a system user to have cross-functional roles to conduct these activities.18 when migrating from non-ex libris product lines to alma/primo, libraries may need to make tough implementation decisions. for example, the university of south carolina migrated library data to alma/primo from innovative’s millennium and ebsco’s full text finder. when the legacy and target products are from different vendors, the system migration can be more complicated in communication, data mapping, data quality, and expected results of data migration. for the usc library, the preexisting duplicate records for electronic resources should have been cleaned up before the migration.19 libraries should address their concerns about key activities during the implementation to get the best possible result. the joint bank fund library had a three-day onsite training in workflows in the middle of the project. it would be much more effective if the library had communicated with the vendor to reschedule the training at a later stage of the migration because library staff were not yet familiar with the lsp by the expected time.20 the university of north carolina at charlotte migrated from oclc’s worldshare management services (wms) to alma/primo after migrating from millennium to wms four and a half years previously. the atkins library went through the second system migration because wms modules did not meet their library’s needs. going through two system migrations in the span of five years was particularly costly and frustrated technical services staff spent more than half of their work time on data cleanup. additional time for data cleaning, workflow design, and training was also needed after the migration to alma.21 fu and fitzgerald studied the effect of lsp staffing models for library systems and technical services by analyzing the software architecture, workflows, and functionality of voyager and information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 5 guo and xu millennium against those realigned in alma, wms (worldshare management systems), and innovative sierra. they discovered that the workload of systems staff could be reduced by around 40 percent, so library systems staff could have additional time to focus on local applications development, the discovery interface, and system integration. in the meanwhile, the functionality of the next generation ils provides a centralized-data services platform to manage all types of library assets with unified workflows. consequently, libraries could streamline and automate workflows for both physical and electronic resources through systems integration and enhanced functionality. this change requires libraries to reconsider their staffing models, redefine job descriptions, and even reorganize the library structure to leverage the benefits of a new lsp.22 western michigan university (wmu) decided to reorganize its technical services department after the alma migration was completed in 2015. after the alma implementation, it was observed that staff spent 38 percent less time working with physical materials. the systems department also shifted its focus from back-end system support to front-end user and other new technologies. wmu consolidated fourteen departments into six and renamed technical services to resource management, composed of cataloging and metadata, collections and stacks, and electronic resources. the lsp administration was shared by four certified alma administrators and one discovery administrator residing in the resource management department.23 although researchers and library practitioners have studied ils selection and implementation processes and the impact of migration on library operation and staffing, only the studies on the rfp and usability testing have focused on decision-making on the ils selection. today, library administrators and leaders face technological change more often while making a transformation to a digital business model. they should understand how decisions are made at different organizational levels when managing change. this study is to fill this gap and help library administrators and leaders to better prepare for future change through the following research questions: • what is the decision-making process and what do libraries consider? • how do libraries evaluate the migration project? • what are the impacts of the system migration on library staffing and operation? • what lessons have libraries learned from the system migration? • what will libraries do differently for the future system migration? methods researchers have adopted both qualitative and quantitative methods for studies about system migration. the literature indicates that both interviews and surveys have been employed to collect data for these studies.24 a usability testing through a set of tasks across systems has also been utilized in a system selection.25 a comparative analysis of vendor documents, rfp responses, and webinars has been applied in studying the impact of system migration on staffing models.26 in this research, the authors used a qualitative method through a survey to understand decisionmaking on system selection, procurement, and implementation. data collection the population for this study is those libraries that implemented or are planning to implement alma. through the eluna membership management site (https://eluna40.wildapricot.org/), the https://eluna40.wildapricot.org/ information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 6 guo and xu authors identified 1,440 libraries in the united states and canada that use at least one ex libris product. with help from sue julich at university of iowa libraries, who manages the site, 1,150 alma libraries were identified. the authors also contacted marshall breeding, the founder and publisher of library technology guides (https://librarytechnology.org/), and obtained a list of 1,134 alma libraries in the united states and canada. comparing the alma libraries acquired from the two different sources, they eventually identified 1,079 libraries from the united states and 55 libraries from canada as eligible survey-participating libraries. the authors developed a 13-question survey in qualtrics. this questionnaire aimed to help participants recall the project experience and offer them an opportunity to self-reflect and give feedback. the survey was distributed via email to the eligible libraries. a few email reminders were sent out to encourage participation. upon the closure of the survey, 291 libraries (27%) completed the survey completely. data analysis qualtrics generates data analysis and reports. the authors conducted a text analysis by categorizing responses to those open-ended survey questions to clarify the characteristics of each response manually and then presented and analyzed data in microsoft excel. findings part i: library profile & background information the participating libraries have diverse profiles in terms of size and geographic location and reflect the point of views from small library to library consortium. remarkably, during the survey, the authors received requests for a complete survey questionnaire so that respondents could coordinate and provide the complete and accurate data on behalf of their libraries. respondents the majority of the respondents in this survey were deans, directors of the library or university librarians, and system librarians (see table 1). also, there were a wide variety of other position titles across cataloging, acquisitions, technical support, and reference, who participated in the survey (see table 2). participating libraries geographic location the participating libraries were located in the united states and canada, and the majority of them were american libraries (see table

libraries indicated that the rfp (request for proposal) process is required for the system migration (see fig. 3). there were a variety of reasons why for those libraries who did not conduct the rfp process (see fig. 4), such as an rfp may not be necessary when migrating systems to the same vendor, there was no increase in expenditure, or the expenditure did not reach a budget threshold (e.g., less than $100,000), or the previous contract stipulated it if upgrading to a new product with the same vendor. another reason was that libraries might have an existing relationship with vendors and would like to continue using information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 12 guo and xu their products. some libraries were given authority by the university administration and library directors to handle the negotiation, or they thought an rfi offered sufficient information to make this decision. other libraries had no choice in conducting an rfi or rfp process for reasons such as their system was outdated and they had to migrate, the decision was made by consortium, or alma was their sole source

project working group (consortium) (see fig. 5). some libraries indicated that their system migration decision was made by university executives (provost, vp finance, cio, and cfo), campus it, aul for library technology, or all librarians/staff. one library reported that the dean of arts, languages & learning services made the selection decision instead of the library or librarians. figure 5. the decision makers. important factors for system selection the authors found that the four most important elements to consider for system selection were budget reality; electronic resource management (erm), bibliographic, and authority control; discovery layers (primo, primo ve); and cloud hosted (see table 14). information technology and libraries march 2023 decision-making in the selection,

technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 16 guo and xu data migrated the most common types of data migrated to alma were bibliographic records, holdings and items, patrons, and circulation data (see fig. 6). some libraries reported that they also migrated other types of data including vendor lists, e-resource data, all available data types, etc. discovery service the survey asked if there were any libraries that migrated to alma and did not choose primo/primo ve for their discovery service. nine libraries reported they were in this case. four of them used summon, four chose ebsco discovery service, and one adopted their locally developed product. when asking the reason for their choices, the nine libraries indicated that they would like to stay with the existing discovery service. additionally, two of the libraries stated that a budget limitation was a part of their reasons, and one library thought the better discovery service for users was the rationale. part iii: feedback on alma migration system migration evaluation the majority of libraries reported that they did not conduct a formal post-migration evaluation. half of the libraries thought the migration achieved their project goals, or met the needs of library operations (acquisitions, cataloging, fulfilment, discovery, etc.) (see fig. 7). figure 7. whether a formal post migration evaluation was conducted. information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 17 guo and xu some libraries also provided their own migration evaluation, including rfp mandatory requirements signoff, availability study, focus groups with library staff, usability testing with students and faculty, feedback and cross-checking with consortium, debrief of library staff, etc. some only did an informal evaluation, which turned out to be not handled well or not very satisfactory. for example, one consortium did a survey on the migration and provided the feedback to ex libris for improvement. other libraries reported that they had not done the evaluation as they did not start the migration process, were still in the migration stage, that an evaluation was not a part of the decision-making process, or that alma was offered as a free product because of their consortial partnerships. valuable lessons learned the authors asked what were the most valuable lessons the libraries had learned from the migration project, and how they would implement the migration differently if they had a chance to do it again. the most valuable lessons concentrated on training, communication, engagement, implementation process, and data cleanup/preparation (see fig. 8). these lessons are shared in greater detail in the discussion section. figure 8. the valuable lessons learned from the migration project. information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 18 guo and xu prospective migration when asking if libraries would consider working with ex libris again if they migrated to a new system in the future, 70 percent of libraries gave an affirmative answer, but some libraries indicated that they would seek other alternatives (see fig. 9). when asked how likely libraries would be to consider implementing an open-source ils, the majority of libraries conveyed that they would not consider open source; only 7 percent of libraries would consider it (see fig. 10). figure 9. whether ex libris products would be considered in the future. figure 10. whether an open-source ils would be considered in the future. information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 19 guo and xu discussion the authors examine the above findings further through the lens of the research questions raised in the literature review section. the decision-making process and factors considered the survey indicates that both rfi and rfp are important for a selection process. fifty-two percent of the libraries conducted an rfi and 57 percent required the rfp process for the system migration. interestingly, even with a variety of sound reasons such as no increase in expenditure, within the budget threshold, existing relationships with vendors, sole source procurement, consortium decision, riders, etc., some libraries still did not roll out the rfp process. besides rfi and rfp, 43 percent of libraries went through a system functionality survey to collect information from library users and colleagues. for most libraries, the library dean or director, alma local implementation team, or alma project working group of a consortium were involved in the decision-making process. in some cases, university executives such as provost, vp finance, cio, cfo, campus it, and associate dean or associate university librarian for library technology made a collective decision. in a rare case, the dean of arts, languages & learning services made the call for the system selection. when considering system migration, many factors can be important. this survey shows that libraries mainly consider budget reality; erm, bibliographic, and authority control; discovery layers; and cloud-hosted systems. it is interesting that most libraries would like to move to a cloud-based system that has better functionality for discovery and electronic resources management. the survey also reveals that library administration needs to find a way to offset the cost increase of the system migration. the lack of comparable system or service offerings in the market also contributes to the decision on system selection. project evaluation project evaluation provides important feedback from both system users and system providers and a great opportunity for libraries to learn. the findings indicate that many libraries do not have a formal assessment process. some consortia have conducted surveys and provided feedback to ex libris, but no response reported to the feedback from ex libris. both libraries and system vendors have lost the opportunity to learn and improve project management. for example, welldocumented complaints on dissatisfaction with ex libris training have not been effectively addressed. some libraries believe a demonstration-focused training model does not provide the same experience as onsite training offers. many libraries have had trouble with acquisitions workflows. the eocr (electronic order confirmation record) and edi (electronic data interchange) processes are standard practices in libraries today to generate order records and create invoices automatically and should be a part of implementation contract to ensure that libraries can operate appropriately after a new system goes live. it is time for both libraries and system providers to consider a formal project assessment as a part of system migration down the road. libraries will not do better if they do not improve today. libraries cannot improve if they do not know where previous projects have gone wrong. a better way to learn from mistakes is project assessment. information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 20 guo and xu impacts on library staffing and library operation some libraries reported that insufficient staffing over the system migration has created additional problems and hardships. some library departments have been stretched very thin in order to work on the migration project in addition to their regular operational duties. however, about onethird of survey-participating libraries have reported that meeting the needs of library operation including acquisitions, cataloging, fulfilment, and discovery is a criterion of project evaluation. the lack of dedicated lsp project migration staff creates a challenge for system migration. most importantly, additional staffing time and technical capacity are important factors that decide if libraries could fully take advantage of the functionalities of a new system. libraries might manage the system migration better by hiring additional technical staff on a project basis to handle technical aspects if staff cannot be released from library operation to focus on the migration project. the system integration and unified automated workflows of a modern lsp can enable libraries to run their operations more efficiently. particularly in a shared environment or network, libraries could share bibliographic records for general collections wider and deeper, which could dramatically reduce the need for both original and copy cataloging. system staff no longer need to install or upgrade proprietary software and maintain servers in house. these changes might cause job insecurity for some library staff. it is critical for library leaders to make adjustments to some job responsibilities or develop new skills to meet new demands. this requires library administration to create a culture of embracing change, learning, and collaboration. staff can take the advantage of a new system by being curious and reassessing previous workflows. library administration could create a flexible structure to encourage learning and collaboration across departments. lessons learned many libraries shared valuable lessons they learned from the migration projects. those lessons concentrate on training, communication and engagement, implementation process, and data cleanup and preparation. training many libraries expressed dissatisfaction with the training provided by their vendor. for example, libraries moving to alma reported that ex libris could have focused more on in-person, postmigration training. as it was, staff felt undertrained because they had access only to online training before the libraries had access to their own data in alma/primo. additionally, ex libris did not have regular trainers for a particular library, so there was less continuity across training sessions than there could have been. some suggest that ex libris do a concentrated several-day initial training for migration so that libraries have a solid overview of the entire system before data exports for testing loads, and then delve into a detailed weekly training that includes more library staff. it seems a good idea to schedule more training sessions after implementation because libraries may not know how the system functions during the implementation period. in an ideal world, libraries would put more contractual obligations on ex libris to train staff more thoroughly. after all, libraries need to hold ex libris more accountable for project outcome. for consortium libraries, they should insist that ex libris provide specialized individual trainers and technical contacts. attending group training sessions conducted by a variety of different ex libris information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 21 guo and xu trainers does not work well in large migration projects. ex libris needs to train the library staff rather than focusing on training the consortium support staff and expecting them to do most of the staff training. ex libris indeed carries a variety of training webinars that are free; however, for bespoke training or intimate training sessions, they charge their customers. a barrier for many libraries is that they just cannot afford to pay more on these bespoke training sessions so they depend on other in-house training and best practices (e.g., work groups, training committees, inhouse power users, etc.) to train/manage the training needs of their library personnel. communication and engagement many libraries express that communication is extremely important and buy-in from stakeholders at all levels is critical to the migration project’s success. investing the initial time to have all stakeholders onboard will pay off. blocking off time for weekly meetings with involved staff and ex libris is key. some suggested asking more questions and seeking to understand the functionality of the new system more deeply. for consortial libraries, librarians can become much closer to each other and learn to seek out and receive help from one another in the ways that they might never do before. the networking can be an invaluable source for mutual support going forward. some libraries reported that due to the lack of communication, an overly sudden decision for the implementation timeline was made at the legislative level. information regarding requirements and expenses was not fully clarified before the process began and came as a surprise during the migration. the whole process felt very rushed by the vendor with insufficient trainings, which turned out to be very dissatisfying. implementation process a system migration is complex and requires a great deal of time, institutional resources, and staff. some key processes needed to be better prepared in advance, such as staff trainings, project plans and major milestones, system analysis, customer inputs for implementation and configuration, data cleanup, physical to electronic processing (p2e), source data extraction, validation and delivery, workflow analysis, fulfillment network, authentication, third-party integrations, data review and testing, go-live readiness checklist, etc. in practice, the migration was often more time and resource-intensive than expected, meaning that libraries found it difficult to complete their part of the process in the contractually-specified time. libraries should clear the decks of core staff to focus on migration, and make sure there are no other major projects occurring at the same time. if staff have insufficient time during the migration window, libraries need to hire temporary experienced staff for the project. this investment will benefit library operation in the long run. the implementation team members should have more dedicated time to be trained so that the library staff are well prepared and knowledgeable in the areas in which they work. it is wise to clean up data as much as possible prior to migration. it would be ideal if the existing workflows were fully documented with diagrams so that it would be easier to determine what parts of the workflows need change. some libraries reported their migration happened during the pandemic with state-issued stay-athome orders in force. it was extremely stressful juggling all of the changes for the library while keeping up with system migration. ideally, it would be better to avoid doing the migration during a pandemic and postpone the migration. but if libraries have no other choices, one benefit is to take advantage of closures for cutover days. the stress of the implementation and trying to get information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 22 guo and xu things done may cause frustrations to boil over. it is advised to manage these situations by adding additional support where needed and by always ensuring that communication is a top priority so that any confusion is kept to a minimum. for consortial libraries, it is important for individual institution members to have their own project managers. the consortial libraries would have tried to standardize more configurations across the consortia, like user groups, circulation settings, item types, etc. some libraries felt the whole migration process was rushed by the vendor, which turned out to be not very successful. libraries should not let the vendor talk them into a compressed, severalmonth migration timeline; instead, they should spend more time in the preparation and implementation process. data cleanup and preparation although it is tedious and time consuming, many libraries suggested cleaning up data as much as possible prior to migration. more pre-migration data cleanup would avoid the post-migration mess. some libraries recommended more stringent cleanup of catalog records, acquisitions data, circulation data, patron records, weeding, etc. it is important to make sure the cataloging structure matches the structure of the new system. had they taken the data review stage more seriously and fully modeled the processes and workflows that would be needed, they would have had fewer data cleanup problems to address after the migration was complete. some libraries cautioned that alma’s p2e (physical to electronic) migration process was more complex than anticipated. they stated that the p2e conversion did not work as it should have, and ex libris should do a better job in the future. due to misalignment of source and target collections, the p2e process resulted in a large cleanup after the migration. a number of libraries would have asked more questions about what data was migrated and to where. ex libris had migrated data that should not have been migrated. as a result, a messy system became a reality. planning for future system migrations when asking what libraries will do differently for a future system migration, many provided very interesting insights. some libraries believed that the system migration put library leadership in a difficult position. they needed to engage all library employees in decision-making and provide staff with the resources they needed to navigate change, experience the vulnerability of learning a new system, and even have difficult conversations with colleagues. at the same time, library leaders are accountable to their parent organizations and subject to budget pressure and mandates to follow procurement processes, which are geared around efficiency and hierarchy rather than promoting democratic decision-making and self-governance. many libraries expressed a concern about training. they stated that they would demand a separate contract for training in the future and put more contractual obligations on system providers to train staff more thoroughly. they would spell out in greater detail what a successful migration would consist of to hold ex libris responsible for outcome. during the bidding process, library staff should be less distracted by smooth presentations but ask difficult questions about system functionality. another concern is about the pricing. one early adopter of alma stated that they learned the risks, rewards, and excitement of helping with a developing product as they felt aleph was a dead end information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 23 guo and xu and did not see many other alternatives. they would have negotiated more strongly with ex libris on pricing considering the immaturity of the product and pricing model at the time of adoption. some libraries felt they were not given competitive pricing, and their costs went up significantly, which constituted a large budget shift. some small libraries believed alma is too big for them, and oclc might be more appropriate for their size of collections and materials. they realized they underutilized a very expensive system. some libraries preferred a customized implementation as opposed to the one-size-fits-all model ex libris offered. they stated that despite learning the new system, they found that the solutions ex libris offered for their implementation rarely worked. they would better off fitting in their own workflows with alma (especially for budgeting). ex libris seems to be not ready to work with single-campus small colleges. other libraries reported that they had multiple people in a project management role, which created communication issues. they learned that in any future migration processes they should have a single project manager empowered to make decisions. for consortium libraries, some libraries suggested taking advantage of cohorts of migrating institutions to share information, issues, and raise common questions. they would have made some local decisions instead of simply going with the consortiums. one consortium experienced a major difficulty that the group implementation took place in different countries. the time difference with their implementation team had added an additional dimension to project management. they would have done an individual migration instead of a group migration since they had a very complex institutional structure. some libraries strongly recommended open-source systems as well. they believed that the trend toward vertical consolidation of vendors is not healthy for the library system market in the long run. with mergers and acquisitions, gigantic companies are formed and might over-control the market and pricing. conclusions decision-making on the selection, procurement, and implementation of a new lsp is a process that requires gathering information and seeking input from library administration, experts, and different levels of stakeholders in a systematical way to ensure the system quality, fitness, and a successful implementation. the findings suggest that libraries should adopt an rfi/rfp (request for information/proposal) or system functionality survey as the basis for system selection. budget, resource discovery, and electronic resources management are the most important factors to be considered in an ils selection. staffing time and technical capability must be addressed before implementing a new system to enable libraries to manage user expectations. insufficient staff and the lack of technical skills could affect the realization of the benefits of a new system. technological change can lead to the shifts of staff job responsibilities and lead to a new way of working together. it is important for library administration to address organizational change when making technological change. a formal project assessment is essential for libraries and system providers to learn and improve collectively. open-source systems could open doors for libraries to seek more customized and affordable systems. research limitations like all research studies, this study has limitations that provide opportunities for further investigations. firstly, because we asked for responses from individuals, not libraries, the findings information technology and libraries march 2023 decision-making in the selection, procurement, and implementation of alma/primo 24 guo and xu might be biased by participants due to individual experiences. secondly, due to the limitation of time, space, and number of survey questions, reported data mainly focused on alma libraries and could not cover migration experiences of libraries migrating to other products or all aspects of system migration. further research would benefit the library community from interviewing participating libraries in a different size, type, and geographic location as well as different system providers. practical implications every new system has its advantages and downsides. to help libraries fully take advantage of a new system, it would be helpful if vendors could evaluate training, physical to electronic (p2e) process, and system affordability. providing training after a system goes live will help libraries implement workflows effectively and give staff better experience. p2e is crucial for ensuring that all relevant information is transferred and maintained in the new system. vendors could address potential p2e issues before a system migration takes place so that libraries might approach data cleanup differently. it would be great if vendors could customize system modules or functionalities as needed by both small and large libraries. this will give libraries flexibility to invest in most needed library operations at different prices to make the system affordable. customer services can be crucial for libraries to continue optimizing the new system down the road. regularly seeking libraries’ feedback can foster a positive customer relationship and benefit both libraries and vendors. acknowledgements the authors appreciate the support of marshall breeding and sue julich for providing the library contact lists. the authors would also like to thank the office

libraries | december 2013 1 hi, litans! forum 2013 i'm excited that 2014 is almost here. last month saw a very successful forum in louisville, in my home state of kentucky. there were 243 people in attendance, and about half of those were firsttime attendees. it's also typical of our yearly conference that there are a large number of attendees from the surrounding area; this is one of the reasons that it travels around the country. louisville's forum was the last of a few in the "middle" of the country--these included st. louis, atlanta, and columbus. next year, forum will move back out west, to albuquerque, nm. the theme for next year's conference will be "transformation: from node to network." see the lita blog (http://litablog.org/2013/11/call-for-proposals-2014-lita-forum/) for the call for proposals for concurrent sessions, poster sessions, and pre-conference workshops. goals of the organization at the board meeting in the fall, we took a stab at updating lita's major goal areas. the strategic plan had not been updated since 2010, so we felt it was time to update the goal areas, at least for the short term. the goals that we agreed upon will carry us through annual conference 2015 and will give us time to mount a more complete planning process in the meantime. they are: • collaboration & networking: foster collaboration and encourage networking among our members and beyond so the full potential of technologies in libraries can be realized. • education & sharing of expertise: offer education, publications, and events to inspire and enable members to improve technology integration within their libraries. • advocacy: advocate for meaningful legislation, policies, and standards that positively impact on the current and future capabilities of libraries that promote equitable access to information and technology. • infrastructure: improve lita’s organizational capacity to serve, educate, and create community for its members. midwinter activities in other governance news, the board will have an online meeting in january 2014, prior to cindi trainor (cindiann@gmail.com) is lita president 2013-14 and community specialist & trainer for springshare, llc.

information technology and libraries | september 2008 andrew k. pacepresident’s message andrew k. pace (pacea@oclc.org) is lita president 2008/2009 and executive director, networked library services at oclc inc. in dublin, ohio. w elcome to my first ital column as lita president. i’ve had the good fortune to write a number of columns in the past—in computers in libraries, smart libraries newsletter, and most recently american libraries—and it is a role that i have always cherished. there is just enough space to say what you want, but not all the responsibility of backing it up with facts and figures. in the past, i have worried about having enough to say month after month for an undefined period. now i am daunted by only having one year to address the lita membership and communicate goals and accomplishments of my quickly passing tenure. i am simultaneously humbled and extremely excited to start my presidential year with lita. i have some ambitious agenda items for the division. i said when i was running that i wanted to make lita the kind of organization that new librarians and it professionals want to join and that seasoned librarians wanted to be active in. recruitment to lita is vital, but there is also work to be done to make that recruitment even easier. i am fortunate in following up the great work of my predecessors, many of whom i have had the pleasure of serving with on the lita board since 2005. they have set the bar for me and make the coming year as challenging as anything i have done in my career. i also owe a lot to the membership who stepped forward to volunteer for committees, liaison appointments, and other volunteer opportunities. i also think it is important for lita members to know just how much the board relies on the faithful and diligent services of the lita staff. at my vice presidential town meeting, i talked about marketing and communication in terms of list (who), method (how), and message (what and why). not only was this a good way to do some navel gazing on what it means to be a member of lita, it laid some groundwork for the year ahead. i think it is an inescapable conclusion that the lita board needs to take another look at strategic planning (which expires this year). the approach i am going to recommend, however, is not one that tries to connote the collective wisdom of a dozen lita leaders. instead, i hope we can define a methodology by which lita committees, interest groups, and the membership at large are empowered to both do the work of the division and benefit from it. one of the quirky things that some people know about me is that i actually love bureaucracy. i was pleased to read in the lita bylaws that it is actually my duty as president to “see that the bylaws are observed by the officers and members of the board of directors.” i will tell you all that i also interpret this to mean that the president and the board will not act in ways that are not prescribed. the strength of a volunteer organization comes from its volunteers. the best legacy a lita president can provide is to give committees, interest groups, and the membership a free reign to create its future. as for the board, its main objective is to oversee the affairs of the division during the period between meetings. frankly, we’re not so great at this, and it is one of the biggest challenges for any volunteer organization. it is also one of my predecessor’s initiatives that i plan to follow through on with his help as immediate past president. participation and involvement—and the ability to follow the work and strategies of the division—should be easier for all of us. so, if i were to put my platform in a nutshell it would be this—recruitment, communication, strategic planning, and volunteer empowerment. i left out fun, because it goes without saying that most of us are part of lita because it’s a fun division with great members. this is a lot to get done in one year, but because it will be fun, i’m looking forward to it. editorial ฀ ฀ ฀ ฀ ฀ ฀ ฀฀ ฀฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀

thinking about it a lot these days. as i write, the lita board is in the process of determining who lita will sponsor in the ala emerging leaders program. the task is difficult. lita has many new librarians who have strong potential for leadership. consequently i feel assured that lita has a strong future because what is an association, if not its members? so one of the questions the board asked was what does it mean to be an emerging leader? when has one emerged? personally, i feel that i am still emerging because there is always more to learn. lifelong learning, isn’t that what librarians are all about? in preparation for my presidency, i attended an american society for association executives seminar facilitated by tecker consultants. they defined four types of influential leadership: servant, visionary, expert, and catalytic. i see all four types of influential leaders within lita and they are all important. the servant leader provides service to others. in a volunteer organization like lita, a lot of servant leadership is being exhibited. these are the people who keep the organization humming, making sure we have the programs and education opportunities that make lita relevant to its members. the most obvious place we see visionary leaders in lita is at our top technology trends; however, it is not the only place where visionary thinking occurs. lita members are often cuttingedge, applying new technologies to solve problems or to provide better solutions and services. visionary leadership is where one sees what the future could look like. lita programs are filled with expert leaders who share their technical expertise and lead the profession in applying those technologies. however, we also have many expert leaders who have important insights into what the association can be. the catalytic leader brings people together and leverages their capabilities. the lita board works with other lita leadership to ensure that our goals are reached and to bring together all of the lita offerings to make membership a comprehensive professional benefit. my challenge as the current lita president with the ala emerging leaders program is to ensure that our sponsored member has a meaningful opportunity to become a superb leader both within lita and within the profession. in addition to attending the leadership training workshops for all of the emerging leaders, each sponsored person will be appointed to some service role within ala or one of its units. the lita board has elected to have our sponsored emerging leader work closely with the officers, in particular our vice president/president-elect mark beatty, on strategic planning for the next two years. i am hopeful that we will learn a great deal from our emerging leader regarding what new members are seeking out of the organization. when i think about a good leader, i think about someone who listens, who allows others to think creatively and to take risks, who inspires, who sees the big picture, who can make decisions and make others understand the reasons for a decision, and who communicates well. john buchan put it this way: “the task of leadership is not to put greatness into people, but to elicit it, for the greatness is there already.” my goal this year, in conjunction with, but not limited to, the ala emerging leaders program, is to grow our new members into future lita leaders. i have been rewarded in all of my work within lita to witness rising stars take on exciting roles and projects. i hope everyone reaps the joys of mentoring new professionals at some point in their careers. in my own leadership role, i take seriously the need to implement lita’s strategic plan. in that vein, the board has created an assessment and research task force that will make recommendations on gathering assessment data and feedback from members. with the appropriate knowledge base, we can ensure that value is being received. the board has also created a working group consisting of the chairs of the education committee, the regional institutes committee, and the program planning committee to make recommendations on our education programs. i have been working with that group to identify new modes of delivering our programs and to ensure that they maintain their relevancy to lita members. lita continues to implement new communication technologies to reach out to its members. the lita blog has now been up for over a year and the new lita wiki is available for use by interest groups and others to allow experts to collaborate in the building of topic-specific resources. sir john harvey-jones framed the question thusly: “how do you know you have won? when the energy is coming the other way and when your people are visibly growing individually and as a group.” i see this happening in lita. what an energizing and fulfilling sight it is! president’s column bonnie postlethwaite bonnie postlethwaite (postlethwaiteb@umkc.edu) is lita president 2006/2007

camtasia this article examines the selection process for and use of camtasia studio software, a screen video capture program created by techsmith. the camtasia studio software allows the author to create streaming videos which gives students 24 hour access on any topics including how to order books through interlibrary loan. h ow does one engage students in the library research process? in my brief time at the downtown phoenix campus library of arizona state university (asu) i have found a software program that allows librarians to bring the classroom to the student. screen capture programs allow you to create presentations and publish them for students to view on their own time. instead of telling students how to do something, we need to show them.1 recent studies show there are numerous benefits to using streaming video in higher education. students that receive streaming video instruction as well as traditional instruction show dramatic improvement in class.2 this article takes a look at how i selected one software program and created a streaming video using the application. i examined three software applications that help create video tutorials and presentations: cam studio, macromedia’s captivate, and techsmith’s camtasia studio. i first experimented with cam studio, which is open-source software. there are limitations to what you can do with software that is free. the screen size is too small and the file size it can create is limited. macromedia’s captivate is good if you want to create a series of screenshots with accompanying audio. i did not choose this streaming video program because i was unsure of the software’s capability, and i had no one to provide technical support. the third choice, the open-source camtasia studio, was the software i selected. there were several reasons why i preferred this software. i had more familiarity with it, and the software is very easy to load and is user friendly. it also has the ability to record a video of everything that is happening on your computer screen.3 another reason i selected camtasia studio was because of the availability of an asu software technician who had experience editing the streaming video. most users view camtasia’s video through adobe flash, but the program also can produce windows media, quicktime, dvd-ready avi, ipod, iphone, realmedia mp3, web, cd, blog, and animated gif formats.4 camtasia performs screen captures in real time. you are able to simultaneously use slideshow software, navigate to a website, and narrate step-by-step instructions. the full version of camtasia studio runs around $300. in addition to the software program, you also must have a combination headset and microphone. a stick microphone will work, but the combination headset will help eliminate any noise that can be picked up by a stick microphone. i purchased a logitech extreme pc gaming headset for about $20. when you purchase the camtasia license online at http://www.techsmith .com/, the customer service department will e-mail you the access code along with a link from which you can download the software. the cd-rom loaded with the camtasia software arrives about ten days later. my first camtasia studio project was a tutorial on how to use the university’s interlibrary loan system. here are the basic steps i took to create a streaming video: 1. preproduction. this involves the creation of a script. 2. production. the actual capturing of the video and audio content. have all websites and programs open and minimized at the bottom of the screen in order to easily select them during the video capturing. 3. postproduction. this is the most time-consuming and involves editing the video and compressing the file for delivery to users. 4. publishing. posting the video to a web server and assessing the material’s success. to see the full 3 minute 53 second streaming video “how to order an article that asu does not own” go to http://www.asu.edu/lib/tutorials/ illiad/index.html. implementing camtasia studio once camtasia studio is installed on your computer, double click on the camtasia studio icon. it will bring up a welcome window where you can select from the following (see figure 1): n start a new project by recording the screen n start recording a powerpoint presentation n start a new project by importing media files n open an existing project i have selected “start a new project by recording the screen.” on the left hand menu there is a task list, and you can select one of the kathleen carlson

“next” button, it brings up a recording options window (see figure 4). select from the following: n record audio n record camera i have selected “record audio while recording the screen.” next you see a window that lets you choose audio settings from the following (see figure 5): n microphone n speaker audio n microphone and speaker audio n manual input selection i have selected “microphone” (see figure 6). the next window is titled “tune volume input levels.” use the input level lever to set the audio input level (see figure 7). figure 1. welcome screen and what do you want to do? figure 5.

appears, which includes instructions on how to start and stop recording. you have the choice of clicking the “record” button on camtasia recorder or clicking the f9 key to start recording. to stop, click the “stop” button on camtasia recorder or click the f10 key (see figure 8). finally click on either “record the screen” or “record powerpoint.” to view your streaming video, click on the saved icon where it says clip bin or go to camtasia toolbar and click on view. then click on clip bin, then click on thumbnails. that’s all there is to it. summary i found camtasia studio to be very user

information technology and libraries | december 2006 digital tool making offers many challenges, involving much trial and error. developing machine learning and assistance in automated and semi-automated internet resource discovery, metadata generation, and rich-text identification provides opportunities for great discovery, innovation, and the potential for transformation of the library community. the areas of computer science involved, as applied to the library applications addressed, are among that discipline’s leading edges. making applied research practical and applicable, through placement within library/collection-management systems and services, involves equal parts computer scientist, research librarian, and legacy-systems archaeologist. still, the early harvest is there for us now, with a large harvest pending. data fountains and ivia, the projects discussed, demonstrate this. clearly, then, the present would be a good time for the library community to more proactively and significantly engage with this technology and research, to better plan for its impacts, to more proactively take up the challenges involved in its exploration, and to better and more comprehensively guide effort in this new territory. the alternative to doing this is that others will develop this territory for us, do it not as well, and sell it back to us at a premium. awareness of this technology and its current capabilities, promises, limitations, and probable major impacts needs to be generalized throughout the library management, metadata, and systems communities. this article charts recent work, promising avenues for new research and development, and issues the library community needs to understand. t his article is intended to discuss data fountains (http://datafountains.ucr.edu) project work and thinking (and its foundation in the ivia system, http://ivia.ucr.edu) regarding tools and services, for use in collection creation and augmentation. both systems emphasize automated and semi-automated internet resource discovery, metadata generation, and rich-text harvest. these areas of work and research occur within the larger realms of machine assistance and machine learning. they are of critical value to libraries as they currently or potentially concern: significant resource savings; amplification and re-tasking of expert effort to better match librarian expertise with tasks that truly require it (through the automation of routine tasks); and better scaling of collections by providing them the technological wherewithal to grow, as appropriate, and better match the explosion of significant available knowledge and information that the internet has accelerated. this article is organized into three major sections: ■ part i details machine assistance work to date in the data fountains and ivia systems project. ■ part ii describes current and upcoming promising research directions in machine assistance. ■ part iii delves into planning and organizational issues that may arise for the library community as a result of these technologies. ■ part i: recent work in data fountains and ivia part i covers work to date on data fountains and ivia. section 1, “a new service and open source software,” describes concrete project work with data fountains, a new open service and suite of open-source software tools for the educational and library communities, in developing practical machine learning to provide machine assistance in collection building. data fountains is an expansion of work based upon the ivia systems foundation.1 it is an effort that has been ongoing and evolving since 1994.2 section 2, “role and niche definition for machine assistance in collection building,” covers recent developments in our ongoing effort to better research and define roles and niches for machine assistance of the types offered by data fountains. the spectrum—ranging from collection building with an emphasis on expertise that receives small assists from machine tools to an emphasis on machine tools that are configured and thereafter assisted through small refinements by expertise—is examined. results from an initial exploratory survey in these areas are summarized. ■ a new service and open-source software—data fountains description data fountains is an internet resource discovery, metadata-generation, and selected, full-text harvesting service as well as the open source (lesser general public license machine assistance in collection building: new tools, research, issues, and reflections steve mitchell steve mitchell (smitch@ucr.edu) is the science librarian for ivia/nsdl data fountains/data fountains projects, science library, university of california, riverside. machine assistance in collection building | mitchell 191 (lgpl) and general public license (gpl) licensed) software that makes the services possible. it is a set of tools for use by organizations and institutions serving the greater learning community that create and maintain internet portals, subject directories, digital libraries, virtual libraries, or library catalogs with portal-like capabilities (ipdvlcs) containing significant collections of internet resources. it is an evolved variant of the ivia system, with which it shares many components. the data fountains/ivia code base represents more than 250,000 lines of primarily c++ code. on the systems level, data fountains operates as an array of independent systems containing crawler, text classifier, text extraction, portal, and database software components customized to the needs of participating projects. each cooperator and subject community works with, fine tunes, and benefits from its own set of crawler(s), classifier(s), and database manager(s), i.e., its own specific data fountain. note that in this article, data fountains’ portal/metadata repository/database management, content management, import-export, or content search/browse capabilities, which are substantial, will not be discussed.3 instead, the article will focus on its machine assistance and machine-learning components. the data fountains system and service has been developed through a research partnership among computer scientists and academic librarians that is beginning to provide technological solutions to some of the major overall problems associated with the scalability and efficient running of ipdvlcs. much project effort is based on applying machine-learning techniques to partially automate and provide help in a number of laborious and costly ipdvlc activities. included here, more specifically, are the following needs/scaling challenges: reducing to some degree the high costs of manually created metadata; better coverage of the ever-increasing number of important internet resources (relatedly, the relatively small size of most library internet collections, where searches yielding very few or no results are common); reducing or making more efficient expert-involved tasks requiring little expertise; and reducing redundant efforts among ipdvlcs (both in content and systems building). by providing inexpensive, universally needed raw materials (i.e., metadata and rich full text representing important resources), the data fountains service is intended to offer major support and resource savings to cooperating ipdvlc participants that otherwise have strong ongoing commitments to their established institutional identity or “brand,” interface or look, system, and, more generally, “established way of doing things.” data fountains viability and sustainability is keyed to providing universally needed service and very generic information products that do not require ipdvlcs to change—this often being seen as prohibitively expensive in time and resources. data fountains is intended to lower barriers for substantive cooperation in collection building and resource savings on the part of large numbers of ipdvlcs by developing, sharing, and distributing the benefits of machine learning in its areas of application. the data fountains service will be useful to a large spectrum of academic and library-based finding tools including metadata repositories and catalogs with internet portal-like capabilities.4 increasingly, library-catalog software is developing more flexibility, including, hopefully, the means by which full marc (machine-readable cataloging) records coexist with more streamlined (and less expensive) records, e.g., dublin core (dc) and other types, and, moreover, metadata records that include or can be closely associated with selected rich full-text, among many other catalog need areas.5 data fountains offers multiple levels of products and services geared to fit the needs of ipdvlcs of differing sizes, subject needs, and desired data “completeness” or depth (this being the amount and type of metadata and full-text needed to properly represent each resource). uses, products, and services overall, data fountains automatically or semi-automatically supplies varying levels of what represents the basic “ore” required by ipdvlcs for internet resource and article collection building: access to significant, previously undiscovered resources as well as the metadata and selected full-text that describe or represent them. this ore is available in both raw (relatively unprocessed) and more refined products depending on the needs of the participating ipdvlc including, perhaps most importantly, the degree to which expertise is available to provide further refinement and how and for whom the material is intended to be used. data fountains multiple product and usage models supports the building of a wide array of ipdvlc collections. a number of usage or service models are supported by data fountains, including: collection development support for single hybrid record type collections the first usage model, based on full automation, involves the utilization of data fountains metadata and rich, fulltext “as is,” without review, to populate a collection. these records can be used by themselves or mixed with other types of records. they can also be used as part of a hybrid collection to undergird another, more primary, or fully expert-created, collection.6 while more accurate, expertcreated collections are not only comparatively more labor intensive and expensive to create and maintain, but often smaller, with narrower and more limited coverage. this has been the infomine (http://infomine.ucr.edu) model that features two distinct collections, with the automatically generated collection supporting, as a second tier of 192 information technology and libraries | december 2006 data, the expert-built content in the primary collection. users can search one or both. internet resource discovery service a second model uses data fountains primarily as an internet resource discovery service where links and titles and other minimal metadata are supplied but where the user’s intent is to identify new resources and build metadata records emphasizing a considerable amount of metadata not generated by data fountains (e.g., different subject schema). this is done by utilizing the targeted link crawler, expert guided crawler, or focused crawler. because little to no metadata/rich-text generation/extraction occurs, this is the least complex of the usage models. crème de la data fountains a third approach, a variation of the second, utilizes only those data fountains records that have been automatically determined, through a user-set threshold, to represent the most highly significant resources (e.g., the top 20 percent). these can be flagged for expert review or automatically harvested without review. the data fountains metadata retained for expert review, post-processing, and improvement can be minimal or full. metadata records intended for expert refinement a fourth approach, which is semi-automated, involves using data fountains as both a discovery service and as a metadata record-building service where employment of records from the data fountains data stream is selective but the machine-created record is routinely retained as a foundation record to be refined or augmented by the expert. metadata records plus full-text a fifth approach is to use the rich full-text selectively identified and harvested from the internet resource, either in addition to the metadata generated or by itself, to populate a collection and greatly boost retrieval. that is, some collections may want to utilize metadata differing from that produced by data fountains but have data fountains perform the service of augmenting their metadata with rich full-text. all or parts of the object and full-text can be harvested. ■ standards, metadata, and full-text data fountains’ record format is dublin core (dc) and features standard research library subject schemas including slightly modified library of congress subject headings (lcsh) and library of congress classification (lcc). as part of upcoming work, development of additional classifiers to apply other subject/classification schemas/ vocabularies will occur, notably ddc and those that can be automatically invoked from the terminology found in the collection objects. cooperators may choose to help develop new formats, subject schemas, and metadata to meet custom needs in collecting and classification. other important metadata generated include: title, creators, description (an annotation-like construct), keyphrases, capitalized terms, and resource language, among a total of thirty-plus fields. in addition to fielded metadata, data fountains delivers selected rich text harvested from the resource. this is important for enhancing ipdvlc retrieval capabilities and user-searching success. the rich text can be harvested verbatim and offered as-is for search or, if this is problematical, further processed into keyphrases. data post-processing, transfer, and product relevance assurance participants determine and download resources of relevance automatically in batch mode via subject-profiled, custom internet crawls and editable results sets created by and for each ipdvlc to reflect its particular interests. these profiled crawls and metadata generation routines are stored and can be re-executed at selected intervals. results are transferred using the open archives initiative protocol for metadata harvesting (oai-pmh) or sdf (standard delimited format) in dc, marc, and extensible hypertext markup language (xhtml) formats. in addition to batch transfers, participants can manually and interactively identify individual records or groupings of records that suit their needs for harvest. selective, interactive, sorting/browsing of results, followed often by evaluation and editing of metadata and full-text fields (as individual records or globally in patterns), is enabled prior to export. these capabilities allow precisely targeted, custom record identification, modification, and downloading. this in turn enables the most general, as well as the most subject-specialized, ipdvlcs certainty in identifying and receiving only records that meet their need criteria. open-source software the software making the above possible is available to all for free through the lgpl/gpl open-source licenses and model. the open-source model should work well for tool development as fundamental as that described. open source of this type generally means that users freely use and perhaps participate in further development of the functionality of the software and, at intervals, contribute their innovations back to the code base for all to use. lgpl/gpl supports a wide diversity of forms of commachine assistance in collection building | mitchell 193 mercial service development. open source has worked well for large applications such as many forms of the linux operating system (a number of variants of this are supported), apache server software, and mysql database management software (all of which are used by the data fountains system). using this model has the intent of cooperatively benefiting the community as a whole. it is the author’s belief that tools of the data fountains type will have wide enough usage within and are crucial enough to the library community to support the development of an open-source community around them. data fountains software is of use to thousands of institutions that build ipdvlc collections. open source also means that the development and evolution of a core tool or system for a community can potentially occur faster and more flexibly, with the proper community support, than many types of proprietary effort. this is needed given the continuing and increasingly greater revolutions in computing power and software potential. the community needs to be able to evolve faster in response to changing conditions, and free, communitybased, open-source software development is one strategy for achieving this. ■ current systems design, development, and features to date, most of the work has emphasized research and development leading to innovations in preferential focused crawling, subject classification using logistic regression, knearest neighbor (knn) and other classifiers, and rich full-text identification and extraction. a major emphasis in systems development has been identifying points of intervention in crawling, classification, and extraction, whereby initial, periodic or ongoing interactive expert input can be employed to improve machine processes and results. that is, the work has emphasized usage not only of fully automated machine processes but semi-automated machine processes intended to interactively augment, amplify, and improve the efforts of experts. experts assist machine processes, and machine processes assist expert judgment/labor. the programming has also been done with an eye toward modularity among different systems components. ■ internet resource discovery/ identification—expert guided and focused crawling a number of crawling systems have been used; currently, for data fountains, three are used that represent two approaches to crawling: expert guided and focused. expert-guided crawling is accomplished by a targeted link crawler (tlc) and an expert guided crawler (egc). tlc is concerned with crawling a user-specified link or list of links. egc differs from tlc in that the single “start url” link given is only the beginning point from which the crawler will either drill down (find onsite links at multiple depths in a site) or drill out (find external links not on the start url site). the result is that, compared with tlc, many more links than just those given the egc crawler initially are crawled. with all crawlers, a metadata record with accompanying rich full-text is generated for each resource crawled. a preferential focused crawler, called the nalanda ivia focused crawler (nifc) after the name of the ancient seat of learning in india, continues to be developed. focused crawling makes possible focused identification of significant internet resources by identifying specific, interlinked, and semantically similar communities of sites of shared subject interest. generally, nifc traverses subject experttargeted regions of the internet to find resources that are strongly interlinked and thereby represent coherent subject-interest communities and sites of shared interest and mutual use (i.e., are often concerned with and contain content similar to one another). communities sharing interests often identify and cite one another through linkages on their internet resources. through this mechanism, these communities and their sites/resources can be identified, mapped, and harvested. preferential focused crawling makes focused crawling more efficient by employing algorithms that can respond to clues in web resource page layout and structure (e.g., using document object models, visual cues, and text windows adjacent to anchor text, among others) that indicate the more “promising” links to crawl. the result is more efficient focused crawling (figure 1).7 the focused crawling process starts with exemplary sites/pages/urls being supplied by participating ipdvlc experts. these highly on-topic exemplars are used to form a seed set of model pages used for training/guiding the crawler. as the crawling progresses, an interlinkage graph is developed of which resources link to one another (i.e., cite and co-cite). highly interlinked resources are evaluated, differentiated, and rated as to the degree to which they are linked to/from as well as for their capacities as authoritative resources (e.g., a primary resource such as an important technical report that receives many in-links to it from other resources) or hubs (e.g., secondary sources such as expert virtual library collections that provide out-links to other, authoritative resources). as hubs, expert-created, high-quality ipdvlc collections of links (e.g., infomine) play an important role as milestones and navigation aids in the guidance of many types of crawling. another automated process works to rate resources, as a second indirect measure of resource quality, by comparing for similarity of content (e.g., similarities among key-word 194 information technology and libraries | december 2006 vocabularies) between the potential new resources and model resources. the most linked to/from authorities and hubs, with terminology most similar to the exemplars, are thus identified and become prime candidates for adding to the collection and for indicating other resources to add. the overall architecture of data fountains involves multiple concurrent crawls and an array of multiple crawlers and associated classifiers on multiple machines (i.e., there are one or more data fountains for each major subject area or major cooperator). areas of expert interaction in focused crawling expert interactive and semi-automated approaches to improve crawling are employed in and constitute special design areas of data fountains since many participating projects and communities have access to considerable subject expertise. there is much promise in amplifying the role of this expertise in the crawling process. experts can create and refine crawls by: ■ determining the most appropriate seeds (exemplary resources) to use (whether found in their own collections or generated from other sources); ■ choosing degree of “on-topic-ness” desired (a precision versus recall setting); ■ determining the total number of resources to be crawled; ■ editing initial crawl results (e.g., de-selecting or blacklisting resources found) with an eye toward generally refining and developing a super seed set of very large numbers of increasingly on-target seeds that are then crawled anew. (this process of refinement and enlargement can be reiterated as desired in achieving increasing accuracy in and numbers of exemplars and therefore accuracy in the final crawl.) ■ in addition, expert truing of crawler web graph weightings (i.e., manually “lifting” the values of selected hubs and authorities) either during or after a crawling run is being explored to improve crawling accuracy. this lifting process can be aided through tools to visualize the crawl so that the expert can quickly identify, among the masses of results, the most promising areas of a web graph for the crawler to emphasize. ■ expert-created blacklists of urls for types of sites or pages that are not valuable can be stored to save future crawling and expert time. there is such a blacklist for each participating data fountains community group and individual. ■ metadata generation— automated and semi-automated subject classification data fountains and ivia embody innovations in automated metadata generation, including identifying and applying controlled subject terms (using academic library-standard subject schema), keyphrases, and annotation-like constructs (figure 2). automated classifier programs apply these and other metadata and are part of a suite of programs known as the record builder. controlled subject terminology applied currently includes lcsh, lcc, ddc, and medical subject headings (mesh). in assigning these, the system generally first looks for html and dc metatags and then extracts these data. with some fields, when these data are not present (which is common), original metadata are then generated automatically. in the case of lcsh, lcc, and ddc, if not present in metatags, or if users choose to override metatag extraction (in cases where metatags are not accurate, such as when they are spammy or when top-page boilerplate metadata is carried onto all pages regardless of subject relevance), then classification processes are invoked. these derive a set of keywords and key phrases from the resource that serve as a surrogate in representing and summarizing its content. then, using a model that encapsulates the relationships between these natural-language terms and the set of controlled-subject terms, the closest corresponding set of controlled terms is assigned. the model is learned from training data sets that consist of large sets of records (more than thirty million in corpora loaned for research purposes by the cornell university library, library of congress, california digital library [cdl], and oclc) figure 1. focused and preferential crawling (courtesy of s. chakrabarti) machine assistance in collection building | mitchell 195 from library catalogs and virtual libraries. with lcc, the aim has been to assign one or more lccs to a resource based on the set of lcshs associated with that resource. svm, knn, and logistic regression classifiers have been used. generally, performance has been acceptable in cases where there were two hundred examples of the usage of a particular lcsh (in a record with a url). unfortunately, as large as the training data sets have been, there simply haven’t been enough records for classification purposes with urls and associated text. this problem will more than likely be resolved shortly as catalogs increasingly incorporate web resources. metadata generation—automated extraction of known, named entities named-entity (e.g., data elements that can be expected to be in a resource and that are placed by authors/publishers within a known textual/markup pattern) extraction is primarily practiced through the simple means of identifying and extracting data elements indicated by html/dc metatags, when present on a page. data for more than thirty dublin core common (and not so common) fields are extracted. with some fields, extraction can be guided, as needed, in the interests of original metadata creation through pattern recognition and profiling, or through classification (e.g., title, subjects, description). ■ rich-text identification and harvest refinement of our “aboutness” measure for identifying the most relevant pages or sections in a resource or document (i.e., those intended by the author to be rich in descriptive information about the topics within and the type of resource) from which to extract text is a continuing pursuit. involved in this quest has been better determination of author-created structures and conventions in document or resource layout (e.g., locating introductions, summaries, etc., and determining/proportioning the amount of text to be extracted from each). more accurate rich-text identification in turn yields more accurate identification, extraction, and application of key phrases and, from these, more accurate controlled subject term and other metadata application. this is at the foundation of many metadata generation processes. crucially, rich full-text is also important from an end-user information-retrieval perspective because the natural-language terminology contained partially corrects for the limitations inherent in many controlled metadata and subject vocabulary/schema approaches (e.g., new or specialized subject terminology is often slow to appear or weakly represented in the often generalist library-standard subject schemas). refinement of the “aboutness” measure in identifying terms indicating that rich text follows is an important and ongoing task that involves formulating fairly intricate text-extraction rules in reflecting conventions in rich-text placement in resources and documents of differing types (e.g., web sites, articles, database interfaces), formats (e.g., html, pdf, postscript), and languages. ■ a modular architecture that supports a federated array of subject-specific focused crawlers and classifiers the architecture that data fountains is based upon is shown in figures 3 and 4. data fountains operates on the systems level as an array of separate sets of bundled crawlers (both guided and focused), classifiers, and extractors; this bundled array of crawlers approach provides greater flexibility and efficiency, as compared with using a more monolithic, single-crawler, multiple-subject approach. a bundle can occupy a whole machine or several can exist independently, as virtual data fountains, on a single machine. instead of one broad, multiple-subject, multipleaudience data fountain that follows a broad shotgun approach to internet resource discovery and classification, there are several vertical, subjectand audience-focused data fountains. a data fountain is intended to exist for each distinct, major subject area and the subject-specific ipdvlc collections (e.g., visual arts, business, horticulture) associated with them. figure 2. metadata choices in data fountains 196 information technology and libraries | december 2006 data fountains systems architecture emphasizes modularity. it has been enabled and assumed that separate components of the system (e.g., the crawlers, classifiers, database management systems) could be developed further for other uses independent of the data fountains system. in addition, as technologies that the system is dependent upon advance, users will be able to more easily swap out and replace older modules. these capabilities contribute to system sustainability. ■ service design and sustainability data fountains was conceived to be a cooperative, nonprofit, low-overhead, cost-recovery-based service intended to sustain itself after start-up. access will be provided to ipdvlc cooperators who demonstrate interest and support for the work and service. by so doing, cooperators share in supporting the continuing evolution and improvement of data fountains. as an additional sustainability consideration, the software has been released as open source so that it can develop and evolve in many directions (to directly fit unique needs) as well as benefit through distributed effort. ■ “small is beautiful”: roles for and advantages of appropriate smallto medium-scaled tools approaches like those data fountains has taken may be among the few ways that internet finding tools can continue to be relevant to the learning/library community and offer the accuracy and significant content needed by that community. the technical challenges faced by the large engines in their quest to cover an infinitude of audiences and internet resources do not need to be grappled with by the community of research libraries and are not faced by focused crawlers and classifiers of the type data fountains relies upon. the latter are better able to develop targeted, more accurate approaches to their subjects because they enable machine assistance for, as well as amplification of, authoritative subject expertise (e.g., librarians) as a core interactive component in the process of finding and describing new resources. the processes involved target more narrowly defined, distinct, and finite subject universes and intellectual communities. this, in turn, allows them to scale appropriately for their tasks and to apply more complex and varied types of metadata for faculty, researchers, graduate students, and librarians, who generally require more precision (and authority) in their finding tools but still need to move beyond collections (even allied) that are essentially catalogs moved forward a notch. the smaller scale of this work also potentially enables innovations in effective linkage and similarity (i.e., semantic) analysis. some experts note that the future of internet searching as a whole may lie in searching federated finding tools based in these techniques.8 such a federation could be an academic’s or librarian’s web of high-quality finding tools. data fountains may offer part of the foundation needed to support such a web. from a related perspective, these tools represent an appropriate approach for library and library-communityscaled resource identification and description tasks that emphasizes perhaps the great advantage the library comfigure 3. interaction of fully and semi-automated and manual collection building processes in data fountains figure 4. overall data fountains architecture machine assistance in collection building | mitchell 197 munity can bring to bear in creating useful finding and metadata generation tools, which no others have. that is, the community’s unparalleled subject and description expertise in finding and ordering significant resources into coherent rich collections might be amplifiable shortly, through machine assistance. if such an effort was sensibly coordinated and focused, and minor modifications in approach and established standards made to enable best use of these new tools, then the best internet finding tools/collections could be made possible yielding high-quality and significant coverage. these collections would benefit by having the capability to catalyze, out of the mass of the web, the resources that constitute much of its intelligent fraction and make this coherently visible and available to learners and researchers. moreover, this could be done in such a way that digital and print record and object collections could seamlessly interact as one, rendering what would be the best information-finding tools/collections without regard to type of resource. this effort in fact has been unfurling for a long time, though, to date, in small and somewhat sporadic, uncoordinated ways. for example, infomine and similar collections have provided credible links to and for the academic community for well over a decade. ■ role and niche definition for machine assistance in collection building exploratory survey an exploratory survey conducted in fall 2005 illuminated new perspectives, desired products and services, and research opportunities as perceived by a sampling of digital library and library leaders in regard to a number of areas involving machine assistance in collection building. generally, areas explored concerned, among others: new roles projected for machine learning/machine assistance in libraries for metadata generation, resource discovery, and rich full-text identification and extraction; new finding-tool niches and opportunities existing in the service spectrum between google and opac; acceptance of streamlined, more minimal, and cost-saving approaches to metadata creation or augmentation; the role of cost-recovery-based service and cooperative, participatory business models in digital libraries. more specifically, the purposes of the survey were to: 1. elicit leading library attitudes in relation to the types of services, software development, and research that generally will constitute data fountains; 2. test the waters in regard to attitudes toward implementing machine-learning/machine-assistance-based services for semi-automated collection building within the general context of libraries; 3. probe for new avenues or niches for these services and tools in distinction to both traditional library services/tools and large web search engines; 4. concretely define data foundations’ initial set of automatically and semi-automatically generated metadata/resource-discovery products, formats, and services; 5. examine attitudes toward the value and roles of rich, full-text in library-related finding tools; 6. examine attitudes toward hybrid databases containing heterogeneous records (e.g., multiple formats, types, and amounts of metadata); 7. gather ideas on cooperatively organizing such services; and 8. generally define new ideas in all interest areas for development of products and services. the survey, comprised of fifty-nine questions, was sent to thirty-five managers of leading digital libraries/libraries/information projects.9 there was roughly a 40 percent return from those targeted (fourteen out of thirty-five). responding institutions and individuals were guaranteed anonymity of response. ■ survey result summary there was considerable agreement on most answers. as such, this initial definitional survey has proven helpful in design and product definition. though the survey sample set/number of respondents was limited and while results need to be seen as tentative, the views expressed are from well-regarded experts in the fields of digital library and library technology, development, and services. in addition to helping define current data fountains services, the survey results also indicated the need for further exploration in the areas of services, tools, overall niche definition, and publicity. while conclusions remain tentative, barring future, larger surveys, some of the more relevant results are as follows: ■ there appear to be significant niches for an automated/semi-automated collection-building/augmentation service given inadequacies in serving research-library users found in google (and presumably other large commercial search engines) and commercial-library opac/catalog systems. survey results indicate a need for services of the types characterized by data fountains. ■ generally, academic libraries get a slightly above middle-value (neutral) grade in terms of meeting shifting researcher and student information needs over the last decade. this indicates that, above and beyond specific library and commercial-finding tools, 198 information technology and libraries | december 2006 there are information needs not being met by libraries in regard to information discovery and retrieval that new services may be able to help provide. ■ there is support, above and beyond creating machine-assistance-based collection-building services, for developing and distributing the free, opensource software tools supporting these services. tools that make possible machine assistance in resource description and collection development are seen as potentially providing very useful services. ■ automated metadata creation and automated resource discovery/identification, specifically, are perceived as potentially important services of significant value to libraries/digital libraries. ■ there is support for the notion of automated identification and extraction of rich, full-text data (e.g., abstracts, introductions) as an important service and augmentation to metadata in improving user retrieval. ■ the notion of hybrid databases/collections (such as infomine) containing heterogeneous metadata records (referring to differing amounts, types, and origins of metadata) representing heterogeneous information objects/resources, of different types and levels of core importance, was supported in most regards. ■ many notions that were foreign to library and even leading-edge digital library managers/leaders (the respondents) two to three years ago appear to be acknowledged research and service issues now. included among these are: machine assistance in collection building; crawling, extraction, and classification tools; more streamlined types of metadata; open-source software for libraries; limitations of google for academic or research uses; limitations of commercial-library opac/catalog systems; and the value of rich full-text as a complement to metadata for improved retrieval. ■ there is strong support, given the resource savings and collection growth made possible, for the notion of machine-created metadata: both that which is created fully automatically and, with even more support, that which is automatically created and then expert reviewed and refined. ■ amounts, types, and formats of desired metadata (very streamlined dc metadata was supported for most uses and contexts) and means of data transfer (oai-pmh was preferred) were specified by respondents. ■ summary of part i data fountains is a unique service and system for inexpensively supporting aspects of collection building among ipdvlcs. developing and utilizing advances in focused crawling and classification, this service automatically and semi-automatically identifies useful internet resources (both open-web as well as closed-collection resources including articles and reports, etc.) and generates metadata (and selected rich text) to accompany them. data fountains is a cooperative service, a free open-source software system, and a research-and-development project exploring machine assistance as well as machine-expert interfaces and synergies in collection building. several useful service niches and roles for the work have been identified and have been or are being developed. ■ part ii: new directions in research this section discusses important new directions in research for machine assistance in collection building as they relate to upcoming and expanding research, development, and prototyping within data fountains and ivia. among focus areas are promising means of: automated classification for applying library standard controlled subject vocabularies/schema, including hybrid and ensemble classification; smarter and more accurate named-entity extraction (e.g., capturing object/article metadata “facts” such as publisher and publishing date); improvements in rich-text identification and harvesting; article/report collection level cocitation and subject gisting functionality; and generally improved expert-guided and focused web crawling. ■ new research in machine assistance for collection building the ivia and data fountains projects have recently received a fourth national leadership grant from the united states institute of museum and library services that supports three years of research and development in machine assistance in collection building. in addition, the national science digital library is continuing funding. the areas that will be worked in are discussed below. these have been determined through experience gained over the last eight years of work in machine-assistance-oriented systems development and dialogue with computer scientists and collection coordinators. these areas of technology work and application, though complex and challenging, are very important. that is, assuming it is important that the learning/library community not be dis-intermediated by such technologies but instead becomes more fully empowered by them. this can only occur through developing a much larger role in actively defining, guiding, and putting the technologies to best possible use. looking into the future, it is clear that libraries cannot simply continue to wait for or rely on good companies like machine assistance in collection building | mitchell 199 google, oclc, or opac creators to deliver them, much like a cargo cult, as they have in the past. to the degree that this is done, there is the risk of becoming vendor vectors blinded by the limitations of these companies and their product lines. these products are often incorrectly assumed to be the known technical and organizational universe of what is possible or doable. the revolutions coming in computing power together with the low cost of this power—which will be almost ubiquitously distributed among users of library collections and services—promise much more change than libraries have seen in the last decade. among the changes underway are those in machine learning and machine assistance in libraries. as the changes take place, organization size may not guarantee much as, over the last decade, librarians and researches have witnessed large academic and other research libraries, with some exception, demonstrate a profound organizational entropy in almost direct proportion to the magnitude of what are essentially paradigm shifts in scholarly communications, information provision, and research. to some degree, these simply reflect larger blockages within the universities and institutions in which libraries are embedded. as these changes play out, it should be noted that history in information or libraryrelated public or scholarly information provision/access probably will not end with google or oclc—wonderful and fairly open companies—just as history in automobile manufacture has not ended with gm, computer manufacture with ibm, or web finding with alta vista. with this as background and in the vein of open planning (as well as open services and open software) and given the size of the work areas addressed and their challenges, much of the projects’ technical planning and direction are being presented in this paper. these areas of computer and information-science research and development, which will affect libraries in many ways, are evolving rapidly into practical application. the current major research areas are: ■ named-entity identification and extraction, and unified models of information extraction and data mining named-entity identification and extraction is concerned with finding and harvesting generally concise factual data—often common bibliographic metadata—present in the targeted resource such as publisher, title, and publishing date. this type of metadata usually is associated with particular collections containing information objects that are often homogeneous (e.g., scientific article collections) and in which author-intended placement of metadata (or data) elements follows an established pattern and location in the object (e.g., an abstract is typically present and indicated in a pattern following presentation of title/author). while making extraction easy is one of the functions of metatagged metadata in internet resources, generally few authors or collection coordinators in academia, or elsewhere, use metatags or applicable naming schema in any significant or uniform way (often, in fact, it is used very sparingly or not at all). extractors therefore must be able not only to identify and harvest metatag metadata, but must discern and then extract specific metadata elements interspersed in bodies of text, as made identifiable by detecting the patterns of occurrence unique to the type of element as it occurs in the object or collection. among the many advances planned for data foundations is the usage of conditional random fields.10 important as well are user interfaces or dash boards that allow configuration of extractors whereby, as patterns of placement for desired data for extraction change in differing collections and types of objects, the tool can be configured appropriately to match the context and task. also under development consideration are more hybrid, unified approaches to and models for data extraction and mining (as applies to text classification), using each to inform and improve the other.11 that is, a family of models is being developed for improving data mining of information in largely unstructured text by using methods that “have such tight integration that the boundaries between them disappear, and they can be accurately described as a unified framework for extraction and mining.”12 much of this work is concerned with generating metadata for article/report-level collections. ■ document-scale learning and classification a strong emphasis in the new work will be on documentscale machine learning, classification, and named-entity extraction in regard to collections of research papers, reports, theses, and monographs. internet-object boundary detection is another important concern. detecting and properly defining compound documents (e.g., web hyper-books on multiple pages or sites) is a goal, as is identifying compound-document points of author-intended entry and intended-user paths (i.e., author-intended main connective threads in distributed or compound documents).13 relatedly, improved internal-document structure identification for better document-level classification and extraction is critical. involved are standard-document internal-structure identification (e.g., abstract, introduction, summary text, captions for tables/figures) including units of rich text and microinformation units of text organized via subtopic.14 methods of document-level word-and-phrase graphing as per 200 information technology and libraries | december 2006 textrank and other means of identifying small-world and micro-information units are currently being pursued.15 a strong emphasis as well will be on examining and implementing new means of co-referencing among documents in collections and new means of identifying latent topics in a well-defined collection. by way of explanation, another term for co-referencing is co-citation. an example of such co-referencing is referencing work, described in papers, that has been funded through the same agency and program or that shares principal investigators in addition to standard bibliographic citation. this will improve on work done in citeseer.ist (researchindex) and similar projects through integrating and advancing the promising approaches of rexa open-source collection-management software.16 the focus of this effort will be on integrating article-level named-entity extraction as well as co-citation and bibliometric-refined subject identification within collections of papers/reports. ■ individual text-classification algorithm and training method improvement new research on individual text-classification algorithms will be examined and applied. the emphasis here will be on prototyping and measuring how applicable recent promising scholarly work might be to library-related metadata-generation challenges. the major focus continues to be in the area of applying controlled, library standard subject vocabularies (e.g., lcsh, lcc, and ddc). many of the improvements relate to advances in individual text-classification algorithms, classifier training and fine-tuning, training-corpora cleanup and normalization techniques, and creating the ability for the individual classifiers to hybridize with other classifiers. of special interest are classifiers that perform well with very large numbers of classes, both small and large amounts of text, and that yield probabilistic estimates in class assignment (e.g., of a particular lcsh). the latter allows both provision of multiple class assignments for resources that have multiple subjects as well as greater accuracy and knowledge of the confidence level of the assignments (thresholds of confidence level in accuracy can be set in applying, or not, a particular classification). more specifically, this work will examine, test, and— depending on test results—refine recently improved variants of the most promising of several classification algorithms.17 among those are: ■ support vector machines (svms)18 ■ logistic regression (lr)19 ■ naïve bayes (nb)20 ■ hidden markov models (hmms)21 ■ knn/knn model22 a number of metrics to measure performance of these and other text classifiers in regard to controlled subject assignment, in both fully-automated and user-interactive (semi-automated) modes, will also be employed.23 ■ hybrid classifiers an important effort will be to test and develop new hybrid classifiers that incorporate the best capabilities of two or more in one classifier. much of the current research has involved developing and improving new hybrids that combine the best of discriminative (e.g., lr, svms, decision trees) and generative (e.g., nb and expectation maximization) techniques in classification. for example, nb is fast but lacking in accuracy, while svms are accurate but can be slow to train. hybrid models can produce better accuracy/coverage than either their purely generative or purely discriminative counterparts.24 various combinations, among others, of lr, hmm, and svm are among the most promising.25 ■ ensemble classification or classifier fusion this constitutes one of the main current directions in classification research and has been applied to a wide range of real-world challenges. classification ensembles are reputed to be more accurate than any individual classifier making them up.26 an important focus is on experimenting with new approaches to automated and semi-automated ensemble classification that involves creating frameworks that support metaclassifiers or classifier-recommender systems to apply multiple classifiers, as appropriate, to the classification task.27 developing classifier ensembles, including the metaclassifiers to guide them, is a major element in making possible the self-service aspect of an open, automated metadata-generation service, given that the metaclassifier is intended to determine the nature of the collection and classification task and assign the appropriate classifier(s) to the job.28 it is probable that expert interaction at suitable points in this process will improve performance. ■ distributed classification classifier ensembles are often used for distributed data mining in order to discover knowledge from inherently distributed and heterogeneous information sources and to scale-up learning to very large databases (often the context for library-related tasks). however, standard methods machine assistance in collection building | mitchell 201 of combining multiple classifiers, such as stacking, can have high performance costs. new classifier combination strategies and methods of distributed interaction will be examined to better handle very large classification needs.29 distributed classification, by nature, would be focused on improving large-scale self-service classification. ■ semi-automated, expert-interactive classification means of enabling semi-automated, expert-interactive classification will be presented.30 there is much scope for building interactive classifiers that engage the tool user or collection coordinator in an active dialogue (e.g., multiple iterations of machine/expert actions and feedback loops) that leads to incorporation of expert knowledge about specific classification tasks, metadata, and collections into the classifier, thus improving performance. that is, an active learning model can be extended significantly for these processes to include both feature-selection and document-labeling conversations, exploiting rapidly increasing computing power to give the user immediate feedback on choices to improve the classification process.31 several different models featuring domain expertinteractive classification and extraction will be evaluated. these vary from being extremely interactive, emphasizing frequent machine assists, to less interactive, where experts profile, launch, and only occasionally refine a primarily machine process. the initial focus will be on the latter models. note that ivia and data fountains have included a metadata generator with semi-automated record builder for years. ollie and hiclass are examples of systems that are more intensively expert-interactive.32 classification tasks and collection types will be characterized as to which lend themselves to frequent expert interactions, occasional interactions, or more fully-automated modes (i.e., little interaction or initial profiling/definition only). ■ classifier training and evaluation techniques as important as direct work on the classifiers is work emphasizing assessment, cleaning, and testing of classifier-training data and classifier-evaluation techniques. involved are training data/corpora-normalization techniques, document-clustering techniques, and classifier bias/variance-reduction techniques. also involved on the classifier side are tuning issues in regard to the data at hand, including improved feature-selection techniques and determining and using confidence estimates in applying/not applying classifications. different approaches to these will be examined, tested, and refined with a range of training corpora. diverse training and test data from assorted collection “types” will include standardized corpora as well as data from participating library or educational community projects. that is, the techniques will be assessed with regard to how they perform with: (1) open web resources, (2) collections of research papers, reports, theses, or monographs (working with rexa), (3) typical campus web-site pages, and (4) mixes of the above.33 each collection-type focus will require differing approaches, algorithms, training, and fine-tuning techniques and will be evaluated through a number of measures.34 ■ improved rich-text identification and extraction for improved classification and user search/ browse rich text is text that has the role of conveying through traditional or new document structures or conventions (e.g., introductions, tables of contents, faqs, and captions for figures) the author-intended subject(s) and intent of the information object. being able to accurately identify and extract this material greatly aids in classifier performance by improving significant keyphrase identification as well as in user retrieval by enabling full-text retrieval. the availability of natural-language text for searching is one means of helping to resolve problems encountered in searching controlled, library standard subject vocabularies (which in turn counteract problems searchers have when only natural-language retrieval is available). both approaches are inherently complementary. improvements in rich-text identification and harvest through improved means of document-structure learning (e.g., identifying text windows around links or captions for figures and tables) will be sought. the lightweight semantic (e.g., use of terms that indicate “aboutness” such as “about”, faqs, introduction, and abstract; rating the frequency and uniformity of application of these terms in a given collection; and proportioning source of harvest) and markup clues will be refined as well. identifying aboutness text, which can be seen as micro-information units of text organized via topic and subtopic, is being pursued through work with rexa and others.35 ■ improved focused crawling focused crawling is an appropriately scaled method of crawling for many library collections (see part i). it is used to discover new internet resources by defined topic terminology and topic web-link neighborhood. topic similarity 202 information technology and libraries | december 2006 and semantic analysis are key measures of significance that are combined with linkage co-citation measures to indicate significance or relevance of a new resource. topic similarity among resources will be increasingly modeled through a topic-linkage matrix (i.e., semantic similarity map).367 new means of evaluating, fine-tuning, and improving basic crawling will be examined.37 rules reflecting the specific semantics of each major subject area are to be developed by participants for crawls/classification. ■ combined mining and extraction that support improved focused crawling in regard to best link pursuit and expert interaction the development of hybrid, unified approaches to extraction and mining can be applied to focused crawling. the processes of data mining, rich-text identification and extraction, and the newest forms of focused crawling are starting to overlap and depend upon one another in important ways (as discussed in the section on preferential focused crawling). another focus for development efforts will therefore be work to more systematically refine bestlink pursuit with an eye toward combining advances in mining, extraction, and rich-text identification in focused crawling. this work will be undertaken to improve the work on nifc. focused crawling will improve in many situations, as well, through use of user-interactive components and data-visualization interfaces (e.g., control boards that visualize an interactive graph to aid in expert “lifting” of the values of specific sites/subtopic neighborhoods to better reflect their significance to the expert). this in turn that will help users guide and tune the crawling, in semiautomated fashion, to better fit the goals and context of a particular crawl. ■ modeling different approaches for a self-service, openly accessible metadata-generation service(s) the data fountains and ivia efforts have some experience with modeling metadata-collection related services, having provided collaborative, scholarly virtual-library service successfully for more than a decade. the data fountains project has improved upon earlier work and represents an automated and semi-automated resource discovery, metadata generation, and rich-text identification and harvest service for cooperating collections. the intent is that data fountains be a self-service operation. in related effort, with co-operators at the national science digital library (nsdl) and library of congress (lc), the data fountains project has been striving to develop self-service dash boards that collection managers can use to configure, profile, and satisfy their needs. by complementing initial profiling with ongoing interactive dialogue, guidance, and refinement, more precise task definition and tool utilization can be achieved. the goal is to have a service that can, through advanced interfaces, engage users in dialogue to help them better determine their options, the tasks involved in achieving them, the capabilities and limitations of the tools available, and therefore, the best choice of tools and practices given their specific service needs and the nature of their collections. ■ summary of part ii there are many fronts of research in machine learning as applied to text processing and new-resource discovery in regard to collection building of various types, relevant to libraries, which have opened over the last few years. the data fountains/ivia research described is looking into just a few of these. for libraries, the borders between computer science, information science, and library science are dissolving rapidly. it would be hard to devise or project forward a five-year plan for a large working library without some understanding of current and oncoming machinelearning and machine-assistance work in each of these disciplines, the many inter-connected organizational/community/technical issues, and without an understanding that goes beyond the domain of current or developing products and services from existing vendors. ■ part iii: issues and reflections part iii is intended to define and address some of the many challenges and issues that are arising or may arise as a result of work on machine-assistance tools in the areas of automated and semi-automated resource discovery, metadata generation, and rich, full-text identification and harvest. included here are reflections on and questions about some of the probable implications and impacts of, as well as roadblocks to, machine-learning technologies applied to collection building. addressed are probable impacts leading to changing roles for libraries, librarian expertise, library standard vocabularies/schema, and the organizations that are the stewards of library standards. these include: ■ what might be the effect of these technologies on library operations, including changes in the areas and nature of expenditure of expertise required, shifts in amount of expertise required, and changes in divisions of labor (both human/human and human/ machine)? machine assistance in collection building | mitchell 203 ■ what are the effects on libraries and end users when the coverage of finding-tool content can be greatly and inexpensively broadened and deepened? ■ how do current or traditional approaches to librarybased practices and standards help foster or hinder these technologies? ■ how will best practices develop in regard to machineassisted activities? ■ how do these technologies amplify and enable or simply prematurely dislodge librarian expertise? ■ who will own these technologies and tools? ■ how open to evolution are library metadata standards and the organizations entrusted with their stewardship? ■ how will these technologies impact these standards? unfortunately, most of these questions will remain as questions unanswered. the few answers offered here must remain as tentative, contradictory, and flawed as those of most who dabble in the cottage industry of imagining library futures. still, in the effort to help map some of the new information landscape that is becoming apparent, these reflections, developed over the course of the last few years, may be small contributions toward defining and understanding what is coming. ■ licensing for automatic agents of libraries it will become increasingly important for libraries to develop licenses with commercial-resource vendors/publishers that allow crawlers/classifiers and other automated programs, to be seen as agents of and for these libraries. it is important that automated agents be allowed to work with (e.g., create or enrich metadata and therefore increase end-user success in finding) both free and fee-based materials in much the same way that an expert bibliographer, cataloger, or public-services librarian would when selecting, creating original metadata for, and providing access to a new commercially vended book intended to become part of a library or other well-defined collection. automated agents accessing and processing fee-based, internet-delivered information objects do so with the goal of improving the finding tools of the institution paying the fee to provide access for users to these objects (i.e., “library users”). thus, they are engaged in a bona fide, fair use of the material by and for the purchasing/subscribing institution. the metadata and descriptive information these tools develop help make the materials they process more visible in collection/finding-tool contexts, a goal which should be desirable by all parties (i.e., end user, subscribing library, and owning author/publisher). ■ new medium, new organization, and an over-proliferation of electronic toll booths and borders another challenge is that internet access to library-collection contents and library catalog-described data, both free and fee-based, is becoming increasingly restricted as libraries, library service organizations, and publishers grope to create special aggregations, with exclusive access for their clienteles. countering this in their adherence to open access, have been, among others, services developed by, for example, arxiv, the institute of museum and library services open archive, cdl escholarship, oaister, citeseer, and nsdl.38 differences in the two approaches may increasingly become an issue. on the one hand there is the broad, longterm community ethic favoring open access to an internet with few walls or borders, and authors enabled to publish directly via the internet through open eprint collections or dual commercial/personal-site publishing/copyrighting of their work. on the other hand there is the fairly narrow definition of an internet information niche in which electronic/virtual services and collection access remain mapped restrictively to the sponsoring physical libraries/collections/institutions/publishers. libraries face a contradiction or tension between these two approaches. the latter mode is a natural effort to retain a tightly held clientele and access model that has characterized physical libraries, reflecting narrowly conceived and decadesold organizational/budget/certification/user models of physical-library services and publisher controls. much of this practice is necessitated by commercial publishers (for whom libraries often have no alternative but to act as vectors), together with the lack of vision for and outdated stereotypes held of libraries by the larger organizations in which they find themselves. at the same time, much of the problem is also due to the inability of libraries to develop new cooperative organizational modes, models, and services that map better to the new medium, map better to new author and user benefits enabled by this medium, and that are better able to exploit fully and fluidly the new medium’s capabilities. the types of compartmentalization of collections, access, and services needed for physical libraries and print, or necessitated by publisher restrictions, are increasingly an obstacle when projected onto internet access and service capabilities. thorough rethinking is needed, just as the educational and scholarly missions of the university as a whole must be thoroughly rethought in the light of internet-associated technologies and capabilities.39 while the information highway must be paid for, over-compartmentalization based on dated organizational and service models is yielding an over-multiplication of 204 information technology and libraries | december 2006 toll booths and border crossings among aggregations and collections. an example has been the emphasis at many university of california campus libraries on the single campus opac rather than the pooling of resources across uc libraries for the strengthening and refinement of cdl’s melvyl union catalog. it is likely that with systemwide, multicampus shared resources, melvyl could improve in all respects vastly beyond the single campus opac. this is noted in the final report of the bibliographic services task force of the university of california libraries.40 overall, institutional parochialism can and has greatly lessened the value and fluidity of the internet as a medium for information provision. the booths and borders of tightly held collections make material harder to find, less visible, and less useful than would be true of more open, expansive collections and archives. as dempsey stated, libraries need to find “better ways to match supply and demand in the open network. . . . we need new services that operate at the network level, above the level of individual libraries.”41 for crawlers and classifiers, the booths and borders that are proliferating in libraries can act disjunctively as barriers, reducing their performance. there are few answers to the challenges that over-proliferation of booths and borders represent. they are often practical solutions to immediate needs. still, projects that are exploring new avenues in organization and open, sharable collections (and the standards they are based upon) should be further encouraged and supported communitywide. these include the open archives already mentioned and systems such as those ivia/data fountains work upon that to provide services for such collections in an open, inclusive, cooperative, participatory manner. while the answer will probably remain a mix of open (reflecting capabilities of media) and closed (reflecting organizational and vendor restraints) collections, it would be progress to move the balance point more toward the middle and away from so many booths and borders. ■ note on the related issue of meta-search libraries often respond to some of these open/closed/ multiple-collection aggregator and “brand” challenges and issues with meta-search services. meta-search can serve to mask the fundamental, growing problem of increasing booths and borders. meta-search, unlike the internet-borne conceptions of open service, collections, access, systems, software, and standards, does not really ask us to change our fundamental assumptions, organizations, or data architectures to match the capabilities of the new information medium. it does not ask us to cooperate more fully and share at the level of collection and data; it also doesn’t encourage uniform-standards adoption and development. while meta-search is a fine answer to certain needs, sometimes it is used as a technical means to attempt to avoid these more fundamental issues. in addition, meta-search can be constraining for user search/access—i.e., it frequently disallows use of significant or unique search and metadata capabilities of each individual database to which it is applied. meta-search in libraries is becoming increasingly central, though it has many current operational flaws. among these flaws are: ■ simplification or dumbing-down of search in order to access lowest-common-denominator fields; ■ clumsy cross-walking among fields, or metadata terminologies that really are not equivalents; ■ difficulty in collating results/eliminating duplicates; and ■ difficulty of matching differing results ranking weightings/systems held by different bases. libraries emphasizing this approach may be increasingly themselves perceived as dumbed down by academics, grad students, or serious researchers, who must reach beyond google, the opac, and meta-search search and display. instead of, or in addition to, meta-search, it might be wise to pursue more fully the hybrid database approach of combining heterogeneous records for multiple collections (and multiple retrieval languages as needed) in one database.42 as computing power increases geometrically and price decreases drastically every couple of years, the challenge that the hybrid-database approach poses in regard to searching and maintenance of very large hybrid databases may soon become less of a problem. this power also implies that meta-search become more useful. ■ library standard controlled subject schema/vocabularies as the promise of automated and semi-automated metadata generation and related tools becomes better known, it may be important for the community as a whole to urge our major subject vocabulary standards organizations, i.e., lc and oclc, to open more fully their standards and input in standard making for wider participation on the part of new communities of researchers, developers, and end users. both organizations maintain important library standard subject vocabularies/schema, lcsh/lcc, and ddc, and related large bibliographic databases and classifier-training data embodying these standards. in this work, both organizations need to more actively seek out and encourage a wider variety of open innovation and development, both within and outside of the library community. this means involving more researchers, end users, and other perspectives in the effort of contributing to the more rapid evolution of these standards in an attempt both to better meet end-user finding needs and machine assistance in collection building | mitchell 205 to facilitate application of the standards through machine assistance. while oclc and lc have been generous in providing their data and standards for ivia research (others that have been generous with training data have been the cornell university library and cdl), most known work on these standards is funneled through their organizations, allies, and organizational filters. this is, of course, critical to a point for coordination; however, if overdone it may unnecessarily inhibit wider pollinations, new perspectives (e.g., a wider variety of linguists, computer scientists, and subject vocabulary/schema experts from other disciplines such as medicine and the sciences), decision making, and faster movement forward. informing the perspective here is that, while there are major costs involved in maintaining and coordinating these vocabularies/schemas, such costs are being borne directly or indirectly by the community in fees paid, monies applied (often public monies through the large participating public university/land-grant libraries, among others), or labor volunteered/provided. lc is a public agency and oclc a corporate cooperative. in many ways then, libraries, through their metadata expert/cataloger community, should be seen as “owning,” as both co-author and funding agent, more of a share in these vocabularies (and other standards in library metadata) than their stewarding organizations. a significant portion of the success of thousands of individual libraries is dependent on the successful evolution (replacement?) of these standards through the facilitation efforts and new roles adopted by these two organizations. ultimately, it must be recognized that in many ways, oclc and lc metadata schema and vocabularies (as well as conventions, styles, and customs in practical application) represent the codified wisdom, in the form of very large knowledge bases, of decades of resource description practice on the part of information professionals in thousands of institutions. the library community is the co-author of these, and oclc and lc are their stewards. when viewing the community as owner, and when taking into account that the community needs to evolve more rapidly with its users to survive, then periodic clarification and renewal of the origin, intent, and understanding of the stewarding organizations and the standards they coordinate might help encourage more rapid, far-sighted change. libraries may or may not sink to the degree that this is realized. in this light, it should be noted that some communities, including path-breaking projects within nsdl, have made well-reasoned decisions not to use these library subject vocabulary standards (carl lagoze, pers. comm.). these are just recent examples, given that abstracting and indexing services/databases, for the journal literature, have in most cases long ago chosen to use their own specialist vocabularies, often supplementing these by enabling key-word or natural-language searching of abstracts or complete full-text. among other core practical concerns here are that the library community’s standards may not be seen as useful and as widely applicable as other information communities may desire. that is, if an important goal is to evolve and expand standards long associated with and emanating from the library community into becoming the standards of new, larger communities outside of libraries, then a moreguarded-than-not approach, which is slow to respond to early adaptors or innovators and slows sensible change, may not be the best path. here it should be said that there are significant ongoing efforts to overcome some of the challenges and better evolve lcsh/lcc. oclc’s faceted application of subject terminology (fast) may represent a step in the right direction.43 having an entry-level vocabulary to translate enduser terminology to appropriate library subject standard vocabulary terms would be of great importance to most types of end user.44 oclc has also been working with the resource description network (rdn) to streamline ddc application.45 there just need to be more of these efforts moving at a more rapid clip. as macewan concluded in 1998, “if lcsh does not change it will sooner or later be abandoned. . . .”46 the same might be said of library subject vocabulary/classification standards. however, in the worst-case scenario, assuming the existing subject standards cannot evolve more rapidly to meet new user needs in information access, collection building, and metadata creation, now may even be an appropriate juncture for a large-scale rethinking and rebuilding, from the ground up.47 the architecture, intent, end-user audience, form, and substance of these standards would need to be rebuilt and expanded. a capability for organizationally responding more quickly to what has amounted over the last few years to far-reaching paradigm shifts would be enabled. now may be the time because, in addition to the questions of the openness/innovation/evolutionary adaptability of these standards, they exhibit significant, long-noted, functional flaws in terms of a non-librarian end user finding success. among others often noted are: ■ misuse/lack of understanding on the part of end users (and, rarely, poor learning materials and guidance supplied by librarians) due to real or perceived complexity, often associated with the use of subheadings and arcane terms that are far from intuitive for users).48 ■ typically sparse application that doesn’t fully represent the number or depth of topics addressed by a work. despite the time needed to create the marc record manually, very few lcshs are applied (often three or less in the university of california’s melvyl union catalog). ■ the arcane and overly general nature of many terms that sometimes do not accord with terminology used by practitioners in the field.49 206 information technology and libraries | december 2006 ■ the lack of currency of terms describing new or recent phenomenon (see discussion of entry vocabulary.50 ■ the lack of uniformity of subject granularity in their application across multiple cataloging institutions for the same/similar works. ■ the significant amounts of expensive expert labor involved in their application. ■ their complexity often at least partially assumes some expert mediation (that may not be available, given that access is increasingly from outside the library) or long-term experience with the vocabulary. ■ overdone detail/complexity, some of it either not extremely useful to researchers and nonlibrarian end users or already instantly verifiable by users. ■ their arcane-ness and complexity, which limits capabilities for machine assistance in application and, thus thwarts a major, inexpensive means for future collection growth, increased coverage, and more useful collections. fortunately, and this is crucial, it turns out that much of the tonic needed for improvement may reside in the areas of inexpensively augmenting, as opposed to changing, the lcsh/lcc/ddc schema/vocabularies. for example, it is probable that most significant objects, when not digitized themselves, will be accompanied increasingly by digitized, representative cores of searchable natural-language rich text, as lc is doing with its table of contents digitization.51 automated and semi-automated tools for rich-text identification, extraction, and end-user searching are showing applicability now (see part i). similarly, keyphrase identification and application can be accomplished automatically with a good degree of reliability; these processes play a role similar to rich text in providing useful retrieval terms and in augmenting subject searching with/without these controlled vocabularies. finally, reasonably good overall subject gisting is occurring in the creation of annotationlike constructs. all of these—rich text, keyphrases, and annotation-like constructs alike—are of great potential value in addressing controlled subject vocabulary/schema inadequacies and in complementing lcsh/lcc/ddc in end-user finding. it is also probable that use of machine means to augment overarching standard subject vocabularies with complementary and much more granular/detailed specialist vocabularies (both expert created and controlled as well as those that are automatically invoked) will shortly be practical and prove very useful. streamlined lcsh/ lcc/ddc could be made perhaps to function as linguistic “switching yards” with specialist vocabularies oriented to them and acting as extensions via the spine provided by the generalist vocabularies (similar to work being explored by vizine-goetz). all of this could be hinged on the synonomy and other term/concept relationships supplied by wordnet or other whole natural-language corpora.52 in such a manner, reconceived lcsh/lcc/ddc can basically work as multi-vocabulary integration and translation tools in cases where the granularity of the subject becomes very fine-grained or specialized.53 such synonymy, linguistic linkages, and switching capabilities would make possible more meaningful and accurate interrelations and more fluid user movement among the vocabularies and concepts of multiple disciplines and multiple-controlled vocabularies/schema. this would also better enable the end user when employing terms actually used by practitioners/researchers/students in their disciplines.54 these and other efforts are crucial because, despite their problems, lcsh/lcc/ddc are comprehensive, overarching vocabularies and schema that, though complex (as are the subject vocabularies of biosis and pubmed/medline, which successfully represent very large subject universes of their own), have done a generally useful job of representing and coherently organizing finding terminology for most known worldly (and unworldly) phenomena. this, on any basis, is no easy task. these library standard vocabularies might best be seen as both essential connective tissue and as spines that could coherently thread many disciplines and interests, and many of the more specific vocabularies, together. without such a spine, interdisciplinarians, researchers/students new to an area, and generalists—whose focus requires wide knowledge often across among many disciplines (and therefore subject vocabularies)—may find themselves handicapped. each suband then sub-sub-specialization might develop its own mutually exclusive and contradictory terminology in a manner that natural-language substitutions such as keyphrase and rich-text availability can only partially fix. many end users and librarians noted the downsides of natural-language-text-only searching two decades ago while using newspaper and other full-text databases offered by dialog or brs. finally, one cannot ignore that lcsh/lcc/ddc have huge established bases of practitioners and metadata records employing them. therefore, their value is large. to summarzie, the solutions to the problems inherent in using library standard subject vocabulary/schema and other controlled metadata will involve the following: ■ openness to extensive hybridization of approaches to rethinking subject vocabularies/schema and other metadata; ■ awareness of, design for, guidance of, and incorporation of new machine-assisted technologies to boost collection coverage and reduce costs of application; ■ embracing machine assistance, as appropriate, as a means of amplifying and extending expertise and application; ■ applying existent technologies for generation of keymachine assistance in collection building | mitchell 207 phrases, description-like constructs, and rich text in order to augment controlled subject vocabularies; ■ developing a better conception of end-user metadata expectations and needs against the backdrop and expectations generated by the web, such as instant end-user access/verification; and ■ making use of specialist vocabularies that might be dovetailed well with and coordinated through standard vocabularies. ■ invoked subject vocabularies—hierarchical and otherwise it is important to track recent research into automated and semi-automated means for creating (often referred to in the computer-science literature as “inducing” or extracting) hierarchical and other subject vocabularies/ontologies from natural-language corpora (see part ii). the intent of this work is to have the natural-language terms used by practitioners directly populate and structure the subject-finding approach. automated induction of subject vocabularies will be useful to augment and increase the capabilities, flexibility, and interactivity of standard subject vocabularies/schema.55 at the very least, and this is important, they could function to automatically suggest synonyms or new terminology for ongoing vocabularies/schema. and these approaches could be put to use in building entry-level vocabularies that front the vocabularies of the standards.56 they could also be used to aid in the semi-automated or automated repopulation/reworking of the standards, if large-scale, from-the-ground-up reworking is deemed necessary at some point. this would be done on a discipline-by-discipline, subject-by-subject basis. ■ resource discovery, search engines, and your library’s subject portal library collections, virtual libraries, portals, and internetenabled catalogs of openly accessible, significant internet resources all function as “hubs” (see part i). along with other types of expert-created hubs, they have played a role in providing most large, sophisticated, commercial search engines with a significant means for modeling and determining high-quality resources and, when accurate, a considerable portion of their accuracy. though google and others do not detail how their search algorithms work, most advanced crawlers highly weight (give authority to) sites that contain large numbers of links to research and other significant resources, especially when expert created. similarly, resources from specific domains such as .edu, .org, and .gov, and institutions such as libraries, universities, and scholarly societies can be identified and more highly weighted. this is another case of the community’s expertise/authority functioning as a knowledge base that, when offered as a public good (as library-created hubs often are), helps better enable directional tools for these commercial and noncommercial crawlers. there is nothing wrong with this as long as the community is aware of its contribution and as long as its efforts are recognized by these businesses. expert library-based subject portals often reciprocate usage by using commercial engines for resource discovery, though this usually represents a minor way of collecting because other expert sources are preferred. ■ enumeration of catalysts for, impacts of, and issues in machine assistance in the library community related to these research and technical developments, the library community needs to think through a great many interrelated and diverse issues and questions regarding (1) impacts of the machine assistance we have been discussing; (2) the possible massive automation of metadata generation and resource discovery in libraries, (3) who will “own” these technologies and ideas, and (4) changes in expectations/roles of metadata practitioners and standards and their stewards, in the following areas: ■ when will machine learning/machine assistance yield reliable, inexpensive, and therefore massive application of metadata on an internet scale, that meets librarian, and more importantly, end-user expectations in terms of usefulness? machine assistance should begin to be factored into long-term planning. ■ what will be the effects of this machine amplification in changing the importance/roles/content of subject standards? that is, how and to what degree will a new means and scale of application change these standards generally, and how they’re perceived and used by end users and librarians and, therefore, be applied by the library community? how might these standards themselves change both in terms of changes in and approaches to vocabulary and schema? that is to say, how would massive, machine-assisted application in and of itself change the makeup of the vocabulary, schema, and the styles/conventions with which they are applied? ■ how might the roles of the stewards of these standards change, given massive application as well as possible interest on the part of other communities? can library standards penetrate and be effectively used by other information communities? what changes in the standards would be required to achieve this? 208 information technology and libraries | december 2006 ■ what are the trade-offs between highly manual or craftsman/guild approaches and highly automated or more industrial approaches to applying metadata? within which contexts, collections, resources, and budgets are these approaches to be best used, either singly or combined in various proportions, in building/expanding a collection? how does each approach best complement the other in library collections? ■ to what degree will changing end-user information usage and access patterns change approaches in regard to collection design and access assumptions, the metadata standards the collections are based upon, and the stewarding organizations of the standards? ■ to what degree may labor and resource savings, as well as the ability to provide for more comprehensive collections, as offered by this technology, dictate changes within the library community in regard to expectations for metadata quality and specificity? in which information-seeking contexts and collections and to what degree will the google-type record or minimal, streamlined dc become, if not a necessity themselves, then a pole toward which library bibliographic metadata evolves? ■ a question self-evident to most but not to all is: to what degree will the nature of the internet itself continue to change our approach to supplying metadata? again, researchers in academic departments no longer need walk across campus to the library by virtue of having many bibliographic details of an object present in a metadata record. increasingly, they can go to the object on the internet and instantly verify the detail for themselves. should libraries deemphasize data elements/fields that are dependably and quickly end-user verifiable in favor of expending more expertise, time, and resources in gisting/ describing the subject, intent, and perhaps even estimated quality or significance of the work? ■ in which specific ways will labor be saved and machines be capable of assisting in resource discovery and metadata generation? that is, what level of automation/semi-automation is acceptable to the community and reliably deployable in production over horizons of one to five years? what level of quality/depth will users accept in metadata designed to occupy the continuum existing between the marc record and the google “record” (this being a large and significant service area; see part i)? how will this technology change old and enable new roles, tasks, and production routines for library subject experts and other staff? how will libraries ramp up and transition into this? ■ will the substantial potential economic advantages of automated or semi-automated generation of library standard metadata such as lcsh/lcc/ddc vocabularies/schema drive a rethinking toward greater uniformity/simplicity/streamlining of these standards and conventions in their application, explicitly with machine application in mind? for example, perhaps only a subset of a whole vocabulary will be used and those that are used will become less detailed and less rich for experts but also—for most end users— less complex and arcane, and more intuitive.57 ■ in some ways, the existence of dc is a recognition that this kind of rethinking and streamlining of library description standards, in the interest of representing and providing access to a much larger scale of communities and resources, is already well under way. what are the obstacles to greater usage of dc? ■ what should the balance be in streamlining metadata for automated application, in relation to its current complexity/depth while augmenting with rich text? from another perspective, what is the balance when considering the oversimplification and loss of descriptive power when using machine methods as compared with that otherwise achievable through use of subject expertise? how will libraries determine best balances of expert and machine in regard to different tasks? how will this be quantified and determined through examination of user retrieval success/satisfaction—with this, in turn, factored against the backdrop of metadata creation costs, fulltext data harvesting and retrieval, and the need for collections with much greater reach? ■ as accurate means of metadata and rich-text generation for/from text objects improve, machine assistance will allow a shifting of expertise to provide better collection coverage and expression of subjectdomain expertise (e.g., in abstracts). how will this new capability for breadth and depth be defined and used in library collections? for example, will new visual, multimedia, and data objects—which the web has made possible on a mass basis and which libraries generally do not cover well—become a major goal in repurposing expertise since these do not easily lend themselves to machine processing (karen calhoun, pers. comm.)? ■ might streamlining and the usage of multiple depths/types of metadata application first require the acceptance within the community of the concept of the multitiered collection/database that supports multiple levels and types of heterogeneous resources representing differing levels of importance to users?58 or, can this need be met through more fully evolved meta-search approaches? ■ helping to structure this metadata heterogeneity might be the sliding-scale application of varying levels of metadata-generation labor expenditures and amounts/type of metadata, with the lower machine assistance in collection building | mitchell 209 and middle-value resources receiving application of streamlined standard vocabularies/schema and rich text, automatically or semi-automatically, at low cost. high-value resources would continue to receive expert-applied, expensively created, complex, and high-quality metadata as well as rich text. libraries already make such distinctions in quality/significance to some degree through purchasing (e.g., departmental collecting profiles/weightings by subject and object type and cost) and order-ofcataloging priority decisions, as well as by student/ faculty input on specific items. more specifically, we would need to discuss and develop criteria in determining the core or peripheral value of a resource for its subjects and user communities and then, based on the judgments derived, appropriately apportion amount and type of metadata and expert labor or machine assistance, on a sliding scale. again, while it should be noted that the library community has generally avoided rendering judgments on the possible use/relevance of a resource to a subject community, libraries nevertheless do routinely make general calls that effectively function this way to some degree. in making this judgement, it would be critical to involve resource users. reviewer-researcher, library user, and librarian evaluations for purchases as well as finding tool/collection-usage statistics for the specific subject or author and item all could be woven into the means by which the core weighting of a resource could be assigned and be refined over time via usage. developing this value is important from a library standpoint. it is a key that may help unlock solutions for some of the community’s bigger challenges, including those revolving around the best marriage of machine assistance with librarian expertise. how do libraries go about making these sliding-scale evaluations with some uniformity, among different collection types and interests, with an eye toward tasking expert and machine? ■ can some of the general end-user search deficiencies commonly acknowledged for lcsh/lcc/ddc be rectified to some extent by automatically/semi-automatically providing rich full-text accompaniment for each record/resource, either in the form of “selected” excerpts verbatim or as processed into significant keyphrases representing this text? how could the presence of this rich text not so much change as augment these standards? for example, rich full-text might be relied upon to contain detail that obviated the need to use certain lcsh subdivisions or other types of marc metadata. could inadequacies/inaccuracies in expert-applied and machine-applied metadata be partially countered, for end-user retrieval purposes, through the presence of rich full-text? rich text, as well as keyphrases/terms and descriptions that serve the same purpose in this context, can now be reliably generated in many cases automatically. what would be the right mix of subject-vocabulary standard metadata and accompanying, selected natural-language text for best end-user success? how might rich-text extraction and searching improve upon searching of whole-object full-text? how much rich text is needed and how distilled should it be? large, whole-object full-text searching can often be a searcher’s quagmire, clouding results rankings and weightings. ■ could a new scale of application and interest on the part of new communities be better catalyzed through the incentive offered by opening up the lcsh/lcc/ ddc subject vocabularies/schema on an open-standards/open-source, free-software model? ■ if development of these technologies is constrained with regard to action/inaction on the part of the community and its stewards, will the standards be replaced—or become obsolete—for major existing or prospective sectors of users? if so, what does this mean for the library community? ■ by and for whom is such standard subject vocabulary/schema application technology developed within the community? classifiers are actually trained through great amounts of what, in many cases, is really community-created knowledge in order to apply community-developed schema/vocabularies. smart crawlers and extractors similarly use (have “learned”) collectively created information patterns, derived from open-knowledge bases of various sorts. who should own these tools/models and how open/ closed should the programming code/ideas be, considering they could not be built without using the collective wisdom embodied in these knowledge bases? these tools exploit decades of labor by thousands of institutions, whose assumption has generally been that the knowledge base and, by extension, the tools that are built on and benefit from it, are and should remain directly or indirectly, public goods. ■ for whom is machine learning/assistance in collection building patented? the ideas, training corpora, algorithms, and data models discussed need to be observed and protected for the public domain to encourage their widespread and inexpensive availability, as well as their evolution. the u.s. patent and trademark office is now more commonly supporting the patenting of whole, generic processes that have heretofore had one or both feet in the commons, as compared with solely granting patent rights in more discrete areas of original invention. it would be unfortunate to find one day that machine assistance in collection building had been patented. this is especially an issue, given that there is little machine learning of interest to libraries that does not mine, apply, and extend the stored wisdom and knowledge that the community has built for decades. 210 information technology and libraries | december 2006 ■ summary of part iii it is important to think through and anticipate a great number of issues and concerns—including those of open models and open development—regarding machine-assistance tools (e.g., classifiers, extractors, and related algorithms/models) that generate library standard metadata, and identify and extract useful natural-language data. it is important because these tools could become central activities in libraries over the next one to five years. reflection here is especially appropriate, given the degree that these tools are trained on exemplars from library collections and come to distill and embody models of library metadata, standards, and expertise that represent the knowledge created over decades through the effort of a whole community. it is important to think through what machineassistance technologies in collection building imply for the future role of the librarian’s expertise. specifically, libraries need to reconceptualize machine-assistance software not as fully automated “ai” but rather, as enabling expert driven, strongly interactive, “servo-mechanisms” that semi-automate some work to increase the reach, quality, and user-finding success within library collections. while it will probably start out with ten or fifteen minutes of expert time saved per record by such tools, this is a lot of time saved when aggregated across the entire community and will only increase. and the community needs to think through what this implies for the evolution of librarystandard metadata, given that machine assistance will increasingly allow for massive and economic application, if a convergence of machine capabilities and machinefriendly metadata standards is architected. this large-scale amplification of usage will quite likely involve changing the value/roles of these standards for the community, as well as for the larger communities that may come to use them at the cost of simplification, streamlining, and a greater reliance on end users to verify some of their own metadata details (often interacting directly with the digital resource). the tools also imply a restructuring of expertise and its application in metadata creation in libraries to reflect a division of labor, with semi-automated machine description processes spent on the mass of useful but midto lower-value materials; with and expert time being spent on high-value resources; and with both types of records residing in the same multitiered, heterogeneous collection.58 finally, needing examination will be the roles of the stewardship organizations in: ■ shepherding the community’s metadata standards during a period of great change; ■ openly evolving the application of metadata standards within the context of machine assignment for the greatest possible good; ■ rapidly evolving the application of metadata standards to retain guidance of and to keep pace with open and proprietary developments in these areas; ■ distilling the metadata knowledge base and wisdom created by the community as this is transformed into the programmatic knowledge (rule bases and models) used by new tools. this knowledge base is a priceless asset for the library community in sustaining service roles in an age of the large-scale advent of commercial-information access, delivery, and ownership. ■ conclusion this article discusses work over the last several years in machine-learning software and services relevant to collection building in libraries. a number of promising avenues for exploration and research are detailed. deeper understanding of and more direct involvement in areas of machine learning are urged for libraries in order to reflect advances in the computer sciences and other disciplines as well as to meet changing end-user needs among information seekers. ■ acknowledgements the author would like to thank the u.s. institute of museum and library

however, all of these were done on relatively small data bases ( 1-5) . of particular importance to this paper is kilgour's article on truncated search keys ( 6) . purpose the purposes of this study are ( 1 ) to determine the comparative effectiveness of the 4,5 and 3,3 search keys, ( 2) to compare two predictive models, and ( 3 ) to test the results with an actual usage survey. method the ohio state university libraries circulation system contained at the time of this study 857,725 titles representing over 2.6 million volumes in the analysis of search key retrieval/guthrie 97 osu collection. the data base used for this study was the search key index file which contained one search key for each title in the master file. the search key is composed of the first four letters of the author's last name and the first five letters of the first word of the title excluding nonsignificant words ( 4,5 key). title words are passed against a stop-list to determine significance. the stop-list contains the words: a, an, and, annual, bulletin, conference, in, international, introduction, journal, of, on, proceedings, report, reports, the, to, yearbook. the search key file is in sequence by search key. for comparative purposes, a second search key file was created and sorted which contained a 3,3 key (the first three characters of the author's last name and the first three characters of the first significant word of the title. ) the two files of sorted search keys were then processed by a statistical analysis computer program. this program created a frequency distribution table of identical keys, i.e., how many keys were unique, duplicated once, duplicated twice, etc. from this table two models were compared. modell: file entry was viewed as a random process with choice of any unique search key equiprobable. this model has been suggested in the literature mentioned earlier. it states that if x;. number of keys will return i matches then the probability of a file search returning i matches may be written: p(i) = xi/ku where ku is the total number of unique file keys. likewise, the cumulative probability for i or fewer matches is i i p(i) = ~ p(i) = ( l x;. )/ku i= l i= l model 2: file entry is viewed as a random process with the choice of any record equiprobable. thus, p( i) = ix;/rt where r t is the total number of file records. correspondingly, i i p(i) = l p(i) = ( ~ ixi )/rt i= l i= l survey: the ohio state university libraries automated circulation system includes a telephone center to which patrons may telephone requests for 98 journal of library automation vol. 5/2 june, 1972 library holdings information and for checking out and renewing books. telephone operators, sitting at cathode ray tube ( crt) terminals, translate the patron's author-title request into a 4,5 search key and proceed with a file search. by having the telephone operators treat te lephone calls as random input to the system and recording the number of matches returned for each search used, results can be generated in the same form that both of the models take, i.e. , i or fewer matches have been returned p( i ) x 100 percent of the time. this is a relatively easy survey to conduct since the output list of matching records for any particular key entry is headed with the exact number of matches which follow. the sample size was 1000 information requests recorded over two one-week periods separated by one month. before these two subsamples were merged, statistical analysis on their individual means (for percent of 10 or fewer matches) signified they were identical at the 99 percent confidence level. results the results predicted by the two models for both a 4,5 and 3,3 search key for 1-10 matches appear in tables 1 and 2. the figures pertaining to the 4,5 key can be compared directly to the data received fro m the survey conducted through the osu library's telephone center. this comparison is shown in table 1 for 1-10 matches. table 1. file access comparisons (4,5 search key).

62.7 66.3 69.3 71.8 73.9 75.7 in table 1 the results of the survey show that 87.8 percent of all searches recorded returned 10 or fewer titles. in modell, assuming that requests of the file are random with respect to search key, it is predicted that 99.5 percent of all searches will return 10 or fewer titles. all predicted percentages for model 1 are consistently higher than observed results. the predicted response in model2 more closely approximates the observed behavior of the system as the number of responses increases. however, model 2 is also consistently higher than the actual survey. comparing model 1 and model 2 only, it is apparent that assuming a random record request more accurately reflects the true usage of a library collection. the lower percentages recorded in the actual survey may be attributable to a number of variables not taken into consideration in this study. clustering due to common english word titles and common names may account for the greater part of this difference. table 2 shows the results of predicted response for a 3,3 search key. in this table, model2 predicts that only 75.7 percent of requests will return 10 or fewer titles. equally important, only 28.0 percent of the requests will return a single record. conclusion in predicting the expected behavior of an information retrieval system, it is more accurate to assume random requests by record than to assume random requests by search key. probability predictions are deceptively high for assumed random key requests and do not reflect actual usage of the file. even assuming random requests by record will produce higher-thanobserved results. data calculated using model 2 should be considered as an upper limit or "ideal" performance indicator. regarding the results of 100 journal of library autvmatio11 vol. 5/ 2 june, 1972 the random record model as the upper limit on effectiveness of the search key, the data gathered indicate that, as the search key is shortened from 4,5 to 3,3, the deviation between the random key and random record models is considerably heightened. the 4,5 search key is more efficient for retrieval of 10 or fewer records from a large file than the 3,3 key (90.2 -75.7 percent ). based on these data, the osu libraries decided to retain the 4,5 search key and not reduce it to 3,3. additional studies should be undertaken to determine the effects of common word usage, common names, and their relation to book usage. secondly, the data presented here could be systematically and randomly reduced in size to predict the behavior of various search key combinations on varying file sizes. references 1. philip l. long and frederick g. kilgour, "a truncated search key title index," journal of library automation 5:17-20 (mar. 1972 ). 2. frederick g.

orders by matching new orders being input with records already in the database. a potential duplicate is reported if there is a match on both the author and the title fields . it was decided at the time of implementation at lewis and clark that this criterion was too restrictive, and clas was programmed to report a duplicate if only the title fields matched . after some months of experience, it turned out that even this requirement was excessively restrictive: a slight variation in the way a title was input would prevent a duplicate from showing up . the criterion was then further relaxed to signal duplicates if either the title or the author's last name matched. this, however, was too broad a net : although no duplicates were missed, ordering a book by wilson or smith produced a tedious list of potential duplicates. hence, the requirement was tightened slightly to look for a match in either the title or the author's last name and first initial. this final criterion is currently serving well the needs of the watzek library. what is important about this evolutionary process is that it illustrates the dynamic way in which a library can "fine-tune" an automated system that is receptive to user modifications . since peas is supposed to be a selfexplanatory system, it lacks any documentation. clas is still a self-explanatory system, but nevertheless a manual has been produced to describe all its features and to record programming information such as the structure of the files . one version of the documentation is kept in machine-readable form so that it can be easily updated to correspond to developments in the program . in conclusion, it can be stated that a library-application software package has been successfully transplanted from one institution to another, from one hardware environment to another, and in doing so has matured into a fuller and more flexible system, which it is hoped will, in turn, benefit other libraries contemplating the automation of their acquisitions operation .2 references 1. jenko lukac, "a no cost online acquisicommunications 101 tions system for a medium-size library," library journal 107:684-85 (march 15,

torrance public library, torrance, california. the information benefit provided to the general public by the developing telecommunications systems will be highly dependent upon the provider's perception of the current and potential role of information in the ordinary interests of life. assessing this role cannot easily be done by standard questionnaire or survey methods because information does not have a conscious function in people's lives. some paradigms from the past and present may, therefore, be of use in articulating the everyday importance of information. the tool paradigm: information as a link between man and his tools or repairing a lost confidence prior to the industrial revolution, most production was carried on in the home, using tools either made or repaired mainly at home. in this cottage industry, each person was very close to and secure in the use of his tools . with the advent of the industrial revolution and the factory system, the worker no longer owned his tools, but went to one place to use someone else's tools. man and his tools began to separate. many used the tools, fewer understood them . this process began to create the "expert." today most of the tools we use-the automobile, telephone, computer termi* a version of this paper was delivered at the meeting on "public libraries and the remote electronic delivery of information (redi)," columbus, ohio, march 23-24, 1981. 102 journal of library automation vol. 14/2 june 1981 nal, etc.-we cannot repair. this has led to a set of latter-day "high priests" upon whom , because of their specific knowledge, we are dependent. i suggest that this trend toward information experts is inimical to a democratic society because of the dependency it creates and because of the pervasivehopelessness it engenders in the public mentality regarding matters as diverse as appliance repair and politics. this process , in a milieu of rapidly developing technology, may seem irreversible . i would suggest, however , that wellpackaged and targeted information could do much to reduce frustration, restore the judgmental effectiveness and the selfconfidence of the ordinary citizen (we are all ordinary for more purposes than not), and to improve citizen confidence in society. for example: i am told i need a clutch job on my car. i can check the flat-rate manual in the library to determin e the amount of time that job should take for my make , model, and year of car. the manual will even give the pric e, but , being a book, it is out of date . in california, each garage must post its hourly rate. suppose the flat-rate manual indicated the clutch job should take three hours and the posted rate is $20 per hour. if the estimate comes back at $150 instead of $60, i know something is wrong. either there is more to the job than clutch repair or it is a rip-off. in either case, even though i cannot repair my car, i can, because of information , make a rational judgment. i am effective in dealing with this problem d esp ite my technological incompetence. the flat-rate manual is a packaged set of information targeted on a specific range of problems, and can function as an imperfect paradigm for what information developm e nt commensurate to technological development should be. the word "they" as a paradigm another indicator of the "information gap" in this society, is a particular use of the word "they." if one listens to the frequency with which people say "they do this," "they don't care," "they 're all politicians," etc., one can grasp the pervasiveness of the "information gap." i suggest that the word "they," so used , almost always indicates an absence of information. this absence is frequently accompanied by suspicion and distrust. the yellow pages paradigm another measure of the importance of information to people in general consists of imagining what would happen if the yellow pages of the telephone book were suddenly withdrawn. there would, i suggest, be a minor revolution. freedom as a paradigm a final perspective on the importance of information may be found in its bearing on human freedom. in the earlier phases of this society's development, freedom consisted of enough space as in horace · greeley's "go west, young man," or in frederick turner's observations on the frontier as a release valve for social pressure in the eastern united states, or d aniel boone needing elbow room. today we live on top of each other and this aspect of freedom is rapidly diminishing. one might view time as a delineator of freedom, as we often say: "if only i had enough time." the absence of the time found in simpler societies, the temporal pressure cooker of today where one's days off are filled with running one's personal business (errands, bill paying, etc.), suggests we have lost much of this temporal freedom . i would suggest that the basic de facto support of freedom now lies with information. information, like knowledge, as observed by francis bacon, is power, and distributed information is distributed power. information awareness contrast these indicators of the public importance of information with a lack of conscious awareness of the significance of information. we do not have an information-prone society. when faced with a problem or interest, i suggest, we are more prone to ask, "what do i have to do?" rather than, "what do i have to know?" part of this reaction is probably due to the fact that when we ask "what do i have to know?" we are faced with another problem in addition to the initial one; i.e., where to get the information. this added effort simply confirms in us our indifference to information, and we take our best shot at solving the problem through decision and action . i sometimes think we have made a virtue of the information incapacity by the way we laud decision making as an indicator of ability. if the foregoing examples are reasonably accurate, we are then faced with a situation in which information is fundamentally important to societal and individual wellbeing, but is not perceived to be so by people in the conduct of their daily affairs . computer-supported telecommunications systems can be the instrument for accelerating information control by a few (this has been much of the trend , so far , as indicated by corporate, research, and technical use of these systems), or it can be used to build information confidence, use, and desire throughout society. this option, i. suggest, is central to the significance of telecommunications systems for a democratic society. if the latter option is to be obtained, i suggest that information will have to be packaged and targeted so well on people 's everyday problems and interests that it will be easier and more productive to say "what do i have to know?" before saying "what do i have to do?" a basic approach to articulating an information service of this kind consists of the following steps: l. determine and prioritize the individual and societal problems and interests of a given community. 2. ascertain the information parameters of those problems and interests. 3. locate and obtain the information necessary to address those problems and interests . 4. organize this information so as to optimally target the specified probcommunications 103 !em or interest to be as easily retrievable as possible. this requires an understanding of the context in which the information is used so that it is optimally relevant, and an understanding of the language and problem articulation common ·to the individuals in the community in order to ensure rapid retrieval. a lesson in interactive television programming: the home book club on qube w . theodore bolton: oclc , inc., columbus,

hirsteditorial board thoughts the iowa city flood of 2008: a librarian and it professional’s perspective d o you like to chase fire trucks? do you enjoy watching a raft of adventurers go over the waterfall, careening from rock to rock? well, this is a story of the iowa city flood of 2008, a flood projected to happen once every five hundred years, from the perspective of a librarian and it professional. n the approach of the flood the winter of 2008 was hard, and we got mounds of snow. the spring was wet that year in iowa city. it rained almost every day. minnesota’s snow melt-off hadn’t been released from the reservoir due to the heavy rains. everyone watched the river rise, day by day. the parks were underwater; the river was creeping up toward buildings, including the university of iowa. in early june, with about a day and a half notice, library staff at the university’s main library, art library, and music library were told to evacuate. one of the first acts of evacuation was the relocation of all of the library servers to the engineering building up the hill—high and dry—literally rolling them across the street and up the sidewalk. although all servers were relocated to engineering, engineering didn’t have enough power in their server room to handle the extra capacity to run all of our machines. the five primo servers that run our discovery searching service had to stay disconnected. with the servers safe and sound, we moved our attention to staff workstations. the personal workstations of the administrative staff and the finance department were moved to the business library. the libraries’ laptops were collected and moved into the branch libraries, which would be receiving displaced staff. many staff would be expected to work from public clusters in the various library branches, locked down to specific functions. as library staff were collecting their critical possessions, the town was madly sandbagging. more than a million sandbags were piled around university buildings, private businesses, and residences. in retrospect, some of the sandbags may have made a difference, but since the flood was so much greater than anticipated, the water largely went over and around, leaving a lot of soggy sandbags. on june 13, the day before the main library was to be closed, the decision was made to move books up from the basement. there were well over 500,000 volumes in the basement, and a group of approximately five hundred volunteers moved 62,000 volumes and 37,000 manuscript boxes from the lower shelves. volunteers passed books hand to hand into the third, fourth, and fifth floors of the building. a number of the volunteers came from sandbagging teams. individuals who had never been in a boxes of manuscripts being stacked on

call number was were working hard side by side with physicians, ministers, scientists, students, and retirees. the end result was not orderly, but the collection was saved from the encroaching river. the libraries at the university of iowa are indebted to these volunteers who helped protect the collection from the expected water. n the river peaks approximately twenty university buildings were closed because of the flood, including the main library, the art building, and the music building. the university’s power plant was closed. the entire arts campus was deeply under water. most of the main roads connecting the east side of iowa city to the west side were closed, and most of the highways into iowa city were closed. interstate 80 was closed in multiple places, and no traffic was allowed from the east side of the state to the west side. many bridges in and around iowa city were closed; some had actually crumbled and floated down stream. so the president of the university, sally mason, closed the university for the first time in its history. most staff would not be able to get to work anyway. many individuals were struggling with residences and businesses that were under water. the university was to be closed for the week of june 15, with the university’s hospitals continuing to operate under strained conditions; continued delivery of patient services was a priority. most library staff stayed home and followed the news stories, shocked at the daily news of destruction and loss. select library it staff began working in the background to set up new work environments for library staff returning to foreign workstations or relocated work environments. at the flood’s peak, the main library took several inches of water in the basement. there was slight rusting in the compact shelving, but the collection was completely saved. a portion of the basement was lower, and the computer equipment controlling the libraries’ public computer cluster was completely ruined. this computer cluster housing more than two hundred workstations library staff and volunteers sandbagging photo by carol jonck moving books out of the basement photo courtesy of the

last day before the evacuation. much of this administrative work could proceed, and during the first week at the business library our finance department successfully completed our end-ofyear rollover process on all our materials funds. staff from the music library, art library, preservation, and special collections were assigned to the business library. the engineering library adopted the main library circulation and reserve departments. the media services staff was relocated to the physics library. the media staff had cleverly pulled most of the staff development videos and made them available to staff from the physics library, thus allowing the many displaced library staff to make progress on staff development requirements. was completely out of commission. the basements and first floors of the art and music buildings were completely ruined, but the libraries for these disciplines were on higher floors. the collections were spared, but there was absolutely no access to the building. n the libraries take baby steps to resume service after a week of being completely shut down, the university opened to a first day of summer school, but things were not the same. for the nineteen university buildings that had been flooded, hordes of contractors, subcontractors, and laborers began the arduous task of reclamation. university staff could work at home when that was possible, and most of the library’s dislocated reference staff did that, developing courses for the fall, progressing on selection work, and so on. staff could take vacation, but few chose this option. approximately 160 staff from the main library and the art and music libraries were reassigned to four branch libraries that were not affected by the flood. all of central technical services (cts) and interlibrary loan staff were assigned to the hardin health science library. central shipping and facilities was also at harden library, thus the convoluted distribution of mail started from here. most of the public machines were taken by cts staff, but their routine work proceeded very slowly. cts did not have access to oclc until the end of their flood relocation, which seriously impacted their workflow. an early problem that had to be solved was providing telephones and printing to relocated staff. virtually none of the relocated staff had dedicated telephones, even the administration. in any given location the small number of regular branch staff graciously shared their phones with their visitors. sharing equipment tended to be true for printers as well. for a few critical phone numbers in the main library, the phone number was transferred to a designated phone in the branch. thus often, when regular staff or student workers answered a phone, they had no idea what number the originating caller was trying to call. staff were encouraged to transfer their office phone number to their cell phone. at the business library, the library administrative staff and the finance staff had their personal workstations, library staff sandbagging photo by donald baxter 8 information technology and libraries | december 2008 was closed for about four weeks. the art and music libraries may be closed for a year. when library staff returned to the main library, there were books and manuscript boxes piled on the floor and on top of all the study tables. some of the main corridors, approximately twentyone feet wide, were so filled with library materials that you almost had to walk sideways and suck in your tummy to walk down the hall. bathrooms were blocked and access to elevators was limited. every library study table on the third through fifth floors were piled three feet high or more with books. for many weeks, library staff and volunteers carefully sorted through the materials and reshelved them as required. many materials needed conservation treatment, not because of the flood, but because of age and handling. many adjustments needed to be made to resume full service. due dates for all circulation categories had to be retrospectively altered to allow for the libraries being closed and for the extraordinary situations in which our library users found themselves during the flood. library materials were returned wet and moldy, and some items were lost. during the flood, in some cases, buildings actually floated down river. the libraries’ preservation department did extensive community education regarding treatment of materials damaged in the flood. the university was very interested in documenting the affect of the flood, and thus the libraries cooperated in trying to gather statistics on the number of hours of library staff and volunteers used during the flood. record keeping was complex, since one person could be a staff person working on flood efforts but also a volunteer working evenings and weekends. n our neighbors the effect of the iowa city flood of 2008 has been extensive, but was nothing compared to the flood in cedar rapids, our neighbor to the north. the cedar rapids public library lost their entire collection of 300,000 volumes, except for the children’s collection and 26,000 volumes that were checked out to library users that week. it staff were housed throughout the newly distributed libraries complex. one it staff member was at the engineering library, one was at the health science library, and two were at the business library. several it staff were relocated to the campus computer center. n the libraries proceed apace despite hurdles as the water receded and workers cleaned and proceeded with air handling and mold abatement, a very limited number of library staff were allowed back into the main library, typically with escorts, for very limited periods of time. during this time it staff was able to go into the main library and retrieve barcode scanners to allow cts staff to progress with book processing. staff went back for unprocessed materials needing original cataloging since staff had the time to process materials but didn’t have the materials. it staff retrieved some of our zebra printers so that labels could be applied to unbound serials. as it staff were allowed limited access to the main library, they went around to the various staff workstations and powered them up so that relocated staff could utilize the remote desktop function. n moving back the art and music libraries were evacuated june 10. the main library was evacuated june 13. the main library passing the books up the stairs photo courtesy of the university of iowa news service gathering strength to

https://doi.org/10.6017/ital.v41i2.15161 julie lane (jlane@peclibrary.org) is technology resource centre coordinator and educational resource consultant, county of prince edward public library and archives. © 2022. prince edward county (pec) is located east of toronto and covers approximately 1,050 square kilometers. pec is a part of the hastings prince edward district school board (hpedsb) and have a total of 6 public schools, one catholic school, and one private school. the other county serviced by our school board is hastings county. the county of prince edward public library (cpepl) system of 6 branches services just under 25,000 residents and countless seasonal visitors during the tourism season. our public school board services approximately 15,000 students across 7,220 square kilometers and 39 in-person schools and a k-10 virtual school across the two counties. starting off a technology column with a bunch of statistics is not exactly how i figured i would write this. however, context is key when discussing equity and access; and in this piece, i intend to highlight how both of those are made significantly easier to achieve for community stakeholders, with the presence of technology and education. when the stay-at-home orders were announced in march 2020 due to the covid-19 pandemic, we knew that we would not be able to hold our scheduled and planned public library programs. we turned to live streaming story times, maker programs, and author visits, all using what equipment we had on hand—tablets, laptops, and the internet. once it became clear that students in the public schools would not return to in-person learning within any short amount of time, all school boards in ontario ensured that enough chromebooks were purchased so that every student had their own dedicated device, with the assumption that providing a device meant all students could participate in remote learning. teachers rushed to transition their teaching plans to an online format; school administrators scrambled to schedule safe device pick-ups for students; and parents were not only juggling professional responsibilities and parenthood, but now teaching and tech support. although school boards provided tools to meet the “classroom” requirements, they could not ensure that every single student had access to a high-speed internet connection, nor could they offer school library access remotely. this is where the cpepl was able to offer support. the global shut down had a significant impact on the relationship that the cpepl had with the schools in our county. a large focus of mine was to rebuild those working relationships to support students, staff, and families, and ultimately demonstrate in actionable ways how the local pu blic library system was there for them. one immediate way i thought we could demonstrate support was through lending our wi-fi hotspots. hotspot lending programs through public libraries have gained popularity over the last few years. although our program had been in place for nearly 5 years, i am always surprised at the number of people that do not realize it is an available resource. with that in mind, i persistently reached out to the school administrators in our area and set up meetings to discuss how our borrow the internet program could benefit those working remotely without reliable internet. wait lists for our 9 available hotspot devices drastically increased, but mailto:jlane@peclibrary.org information technology and libraries june 2022 gathering strength to combat access inequality | lane 2 our patron community was incredibly supportive of our students and would frequently request that their loan, which is at maximum 7 days in length, be passed to a student. though connecting families with internet hotspots was helpful for the required online learning, we could not fill the gap completely. if we had an unlimited communications budget, the situation would have been easily remedied, but, as we all know in the library world, budgets can be very tight. this fact pushed us to find creative ways to bring as many resources as possible to the students, staff, and families in our community. to broaden the reach to individual schools (and staying persistent with that outreach), i focused on not only ensuring that school communities knew what physical resources the library had, but also what electronic resources were available. these conversations and emails with school administrators led me to get in contact with the curriculum coordinator at the board office. this connection was a complete game changer. instead of us, as a public entity outside of the school community, contacting individual schools and trying to build relationships with teachers, librarians, and administrators, we had the person who oversaw all of the school librarians, library technicians, and curriculum development for the k-8 grades on our side. the coordinator was on board to help us make the desired connections with the schools in a number of ways. she put us in contact with the curriculum coordinator for the secondary grades (9-12) and our program and service list was sent from the board office to every teacher, principal, school librarian, and library technician in prince edward county. we were then able to set up a meeting with the coordinator of assistive technologies for the board, which set us on a track to completely revamp how we marketed and allocated our resources to schools. it became clear in our first conversation that we needed to get students connected with their public libraries as quickly and efficiently as possible. with students split between in-person learning, virtual learning, or a combination of the two, with still minimal to no access to school library borrowing, the online resources of the public library system seemed like the perfect solution. not only would connecting students, staff, and their families with their local public library be a way to get everyone reading, but we were fulfilling the opportunity to ensure that everyone had genuine and equitable access. what the school board had observed was that the required shift to remote learning made the inequality of literature access glaringly obvious. students who relied on their school library for reading were not getting that opportunity and students who had individual education plans were jumping through hoops to get digital copies of material. so though everyone had a school supplied chromebook, not everyone had the same access. this is where public library subscriptions to hoopla and libby came to the rescue for providing current and popular literature in a variety of electronic formats for students to immediately access for both course reading and leisure enjoyment. connecting with like-minded, growthand education-oriented people is incredibly empowering. the curriculum coordinators at the board office were so enthusiastic about connecting students, staff, and families in our school board with their public library that it made the next parts of the process not only successful, but fun as well! the curriculum coordinators and i created a presentation that we brought first to school administrators in prince edward county. having public library advocacy come from the school board was incredibly influential and a big step toward issuing library cards to students. once we had buy-in from the school administrators, we circulated registration forms for families to fill out and get everyone in their household public library access. we found that the easiest way to do this information technology and libraries june 2022 gathering strength to combat access inequality | lane 3 was using google forms. it was simple for parents to fill out and easy for library staff to glean the required information for card registration. since the library was also working with the virtual school, we needed to be able to issue library cards even if some students were not in our catchment area. it was common for virtual classes to consist of students from the smallest village in pec and all the way up to the northern most part of hastings county, a full 3 hours’ drive away. cpepl was able to accommodate this need. pec is a tourist destination and frequently issues cards for visitors staying in the area for an extended period of time under the rule of if you “wo rk, live, or play” in pec, you are eligible for a public library card. once library cards were set up or renewed for all families who requested them through the google form, i got to work teaching students and staff how to access library resources. after communicating with the curriculum staff and public school administrators, it was decided that creating an information presentation on getting started with hoopla was the best course of action. hoopla is an incredibly intuitive application in regards to the format possibilities (ebooks and audiobooks) as well as adjustable features within each format. the available settings and adjustment options make the reading experience comfortable and accessible as possible for users. also, since there is no wait time to borrow materials, this allowed entire classes learning remotely to all check out the same title and read together. the material presented to students was easy to understand and interactive. the session provided ample time for students to follow along and test each feature in the hoopla app with their own individual book selections. the best part? this presentation was just the starting point. while we were only able to schedule and virtually deliver this presentation at two in-person schools, the other five schools in pec and a number of primary classes in the virtual school still participated in the google form for library card registration. teachers started asking what else the public library had to offer to enhance the curriculum delivery with additional resources. many community teachers were reminded of the public library’s services and resources (beyond just hoopla) and reached out for class visits or access to materials. other schools outside of our prince edward county catchment reached out and connected with their local public libraries, or vice versa. we are still working to develop ways to meet the needs of students, staff, and their families through the public library. some schools in the northern area of the region have students coming from multiple, different public library catchment areas, and most of these libraries do not have the same resources as others, especially in the case of smaller systems. this posed an issu e of equitable access for students: why should some students in the class have access to library online resources, and some not because they come from different/smaller communities? we were able to mitigate this issue with the virtual school, but for students attending in-person learning, we could not give library cards to every student in the school board. thankfully, another public library system in our area stepped up their access to offer virtual library access to any student or teacher in hastings county (so everywhere except prince edward county). this recognition of the importance of equitable access enabled students to not only regain access to a public library system, but it also ensured that all students could access books in the way that best suited them. when i ask a class if listening to an audiobook counts as reading, it amazes me that the majority of the class say “no.” or if i ask students if they had ever read an ebook, some would say it was not a “real” book. these comments and notions are not only untrue, but they are information technology and libraries june 2022 gathering strength to combat access inequality | lane 4 also exclusionary. countless students need other formats than just printed materials. how many would benefit from listening to an audiobook along with reading a printed version? how many students dislike reading because it is just hard to see the words, but if the text was more spaced out, or a different font, it would make all the difference? how many times is a student not able to access a book they want because all available copies are already checked out at their school library? these are issues students in the classes i work with face. having a public library card can significantly ease these barriers to access. all in all, we processed hundreds of card requests and renewals and were able to powerfully illustrate to teachers how they could meaningfully integrate public library resources into their classrooms, either virtually or physically. our requests for library visits came back up to prepandemic levels, but we were working with more schools than we had previously. teachers were, and still are, reaching out and asking if we can get extra copies of books, or if we can lead virtual novel studies. one of our more popular pieces of progress is the integration of our coding programs with other subjects. currently, i am running a ukulele program where students are writing group arrangements using binary code as the basis for composition. we have classes doing art projects with robotics and integrating math learning objectives. we have done virtual story time and connected the story to creating scratch programs. the possibilities are endless , and now that we once again have the interest from teachers, we are working with them to support their students and all the learning that comes with incorporating technology and maker-thinking into a classroom environment. the momentum has not let up, and we are beyond thrilled. our communities and local school board have embraced the reality that public libraries are more than just books. public libraries are a critical part of any community and have the power to be a meaningful component to education at all levels. having schools and all educational stakeholders using public library services not only broadens the reach of a public library, but also broadens our advocacy potential. we know there is still a long way to go in terms of genuine equitable access, especially when it comes to technology. internet connectivity and technology literacy are just the tip of the iceberg, but when organizations support each other to truly serve their community, collectively, that is how you make change. 184 information technology and libraries | december 2009 thomas sommer unlv special collections in the twenty-first century university of nevada las vegas (unlv) special collections is consistently striving to provide several avenues of discovery to its diverse range of patrons. specifically, unlv special collections has planned and implemented several online tools to facilitate unearthing treasures in the collections. these online tools incorporate web 2.0 features as well as searchable interfaces to collections. t he university of nevada las vegas (unlv) special collections has been working toward creating a visible archival space in the twenty-first century that assists its patrons’ quest for historical discovery in unlv’s unique southern nevada, gaming, and las vegas collections. this effort has helped patrons ranging from researchers to students to residents. special collections has created a discovery environment that incorporates several points of access, including virtual exhibits, a collection-wide search box, and digital collections. unlv special collections also has added web 2.0 features to aid in the discovery and enrichment of this historical information. these new features range from a what’s new blog to a digital collection with interactive features. the first point of discovery within the unlv special collections website began with the virtual exhibits. staff created the virtual exhibits as static html pages that showcased unique materials housed within unlv special collections. they showed the scope and diversity of materials on a specific topic available to researchers, faculty, and students. one virtual exhibit is “dino at the sands” (figure 1), a point of discovery for the history not only of dean martin but of many rat pack exploits.1 the photographs in this exhibit come from the sands collection. it is a static html page, and it provides information and pictures regarding one of las vegas’ most famous entertainers. this exhibit contains links to rat pack information and various resources on dean martin, including photographs, books, and videotapes. a second mode of discovery within the unlv special collections website is its new “search special collections” google-like search box (figure 2). this is located on the homepage and searches the manuscript, photograph, and oral history primary source collections.2 the purpose is to aid in the discovery of material within the collections that is not yet detailed in the public online catalog. in the past researchers would have to work through the special collection’s website to locate the resources. they can now go to one place to search for various types of material—a one-stop shop. the search results are easy to read and highlight the search term (see figure 3).3 the third point of access is the digital collection. these collections are digital copies of original materials located within the archives. the digital copies are presented online, described, and organized for easy access. each collection offers full-text searches, browsing, zoom, pan, figure 2. unlv special collections search box figure 1. “dino at

in las vegas, and the clark county heritage museum. it even provides standards-based activities for elementary and high school students. this project was funded by the nevada state library and

director peter michel selected the content. the team included fourteen members, four of whom were funded by the grant. christy keeler, phd, created the educator pages and designed the student activities. new collections are great, but users have to know they exist. to announce new collections and displays, special collections first added a what’s new blog that includes an rss feed to keep patrons up-to-date on new messages (figure 5).5 another avenue of interaction was implemented in april 2009 when special collections created its own facebook page (figure 6).6 students and researchers are encouraged to become fans. status updates with images and links to southern nevada and las vegas resources lead the fans back to the main website where the other treasures can be discovered. special collections has implemented various web 2.0 features within its newest digital collections. specifically, it added a comments section, a “rate it” feature, and an rss feature to its latest digital collections (figures 7, 8, and 9). these latest trends enrich the collections’ resources with patron-supplied information.7 as is apparent, unlv special collections implemented several online tools to allow patrons to discover its extensive primary resources. these tools range from virtual exhibits and digital collections with web 2.0 features to blogs and social networking sites. special collections has endeavored to stay on top of the latest trends to benefit its patrons and facilitate their discovery of historical materials in the twenty-first century. figure 8. “rate it” feature

digital collection continued on page 190 190 information technology and libraries | december 2009 as previously mentioned, these easy-to-use tools can allow screencast videos and screenshots to be integrated into a variety of online spaces. a particularly effective type of online space for potential integration of such screencast videos and screenshots are library “how do i find . . .” research help guides. many of these “how do i find . . .” research help guides serve as pathfinders for patrons, outlining processes for obtaining information sources. currently, many of these pathfinders are in text form, and experimentation with the tools outlined in this article can empower library staff to enhance their own pathfinders with screencast videos and screenshot tutorials. reference 1. “unlv

(cti) sells a turnkey backup system based on an apple ii plus microcomputer, with two mini-disk drives using 5 '14 " floppy diskettes, a tv monitor, and a switching system connecting the apple to the libs 100 console and terminals. software designed to interface with the clsi system is part of the package. the backup collects and stores data for communications 297 check-ins and checkouts and then dumps them into the database by simulating a terminal when the mini-main-frame is operational again. this requires dedicating a terminal to this process until complete. it can also be used alone as a portable unit for circulation purposes, or with any of the many applesoft packages available, or with an applesoft program of the user's own design. our initial experience in great neck was with a borrowed demonstration system, set up by a sympathetic cti representative on the spur of the moment in tandem with and connected to the main library checkout station's crt laser terminal after several days of downtime. the circulation staff cheered as the familiar prompts appeared on both screens. they used the clsi equipment which they were accustomed to operating and the computer room staff learned to operate the cti system. the ease with which the apple could be transported to different locations in the building and the immediate relief it gave wherever it was connected, sometimes one checkout station, sometimes another, led us to put off deciding on a permanent installation at first. we thought it might be more advantageous to keep it on a rolling cart and use it wherever a terminal was down, or wherever the traffic appeared to be heaviest. we continued in this manner for a while even after both of our own apple systems were delivered. it soon became apparent that the apple and its accompaniments, especially the switching system with its dangling cables, was a nuisance at the checkout counter. people with piles of books or records tended to nudge it dangerously close to the edge or jiggle its connections loose. the circulation staff didn't like waiting until someone from the computer room could be spared to bring up the system, secure the connections, and turn on the apple. also, although the apple is a very reliable instrument which has given us negligible downtime, bumpy rides over various floors, carpets, lintels, and textured tiles occasionally loosened its chips and rendered it, too, inoperative. cti representatives were called in to make a more permanent installation for the apple in our computer room, a simple operation requiring some additional cable. se298 journal of library automation vol. 14/4 december 1981 lection of the terminals to be attached as alternate backup or dumping sites was not so easy, however. the choice of the primary backup site was not a problem, since one of the two checkout stations flanking the main door was fairly obvious. but the second terminal which would be preempted for dumping was a more difficult decision. dumping sessions vary in length depending on the number of records to be processed and the activity on the rest of the libs 100 system. in our library, we find it takes about an hour to dump 100 to 150 transactions. this appears to be slower than average and may well be due to the extremely high level of system activity. thus, dumping 1,000 transactions would take a full working day. we had been online for such a short time that great backlogs of patron and material data entry from new registrants and unconverted books had developed and were a high priority item. neither the circulation department, which was handling registrations, nor technical services, which was handling materials, felt they could afford to lose much terminal time for dumping. thus, the reference department's information desk terminal was reluctantly chosen as the alternate terminal on the grounds that they only did inquiries formaterials which borrowers could locate by means of searching the catalog and making trips to the shelves. if necessary, information desk personnel could step across the aisle to the circulation department and use a terminal there. the permanent installation was set up in this way for one backup system , while the other one remained mobile in the event we wanted to use it at one of our three branches. only the switching box and cables were really unmovable. the apple, drives, and monitor could still be disconnected and moved about at will. experience over the last few months with this arrangement demonstrated that, all things considered, it is unwise to attach two public service terminals to one apple, in spite of the pressure it puts on behind-thescenes operations to lose terminal time in the event of an extensive dump. the reaction of the public to being told a terminal that usually helped them was inoperative has been so negative it outweighed the delays in data entry. therefore, a change in the current configuration will soon be made. meanwhile, we realized the second backup system was not being used to greatest advantage. when the libs 100 was down, the next most pressing demand after main library checkouts were checkouts at the largest branch, located near the railroad station. we were collecting about thirty transactions an hour or less at other locations in the main building while the station branch staff were writing down twice that amount or more and explaining to their public that the computer was down. it seemed important to pursue the possibility of connecting one of the station branch's terminals to the second apple while keeping the apple itself in the computer room in the main library. not only was there even less space in the branch for another piece of hardware on their counter, but staff training and hardware control presented a greater problem since many more part-time people were employed there. cti worked on the problem for about two months, resolving it through the addition of a modem to the basic configuration. in this new installation, which we did ourselves with phone assistance from cti, and which has been operational for three weeks as of this writing, the dedicated phone line connector for the branch terminal is removed from its port on the libs 100 console and inserted into one of the switching box connectors. the apple is turned on as usual and the crt laser terminal at station branch appears to operate normally. in fact, it operates so closely to its usual libs 100 mode that staff members forget they are not online with the libs and call up to find out why inquiries don't work. we are still experiencing a significant amount of downtime with our libs 100. some of this is attributable to our relatively full storage, requiring us to perform housekeeping routines frequently, but the rest is a result of system failure. now, however, because of the apples, this causes far less anguish in the circulation department. when the libs 100 goes down, the permanently connected backups are switched on in the computer room by their staff and circulation clerks continue checking materials out on their regular clsi equipment in the main library and station branch. on days when housekeeping chores are scheduled, the console operator's job includes turning on the apples so we can begin serving the public when the doors open at 9:00 a.m. unless downtime persists for more than a day, no other routines are done except checkouts. under some circumstances, certain materials might be checked in on the apple, but it is not desirable to do this for newer materials on which holds may have been placed. when the libs 100 is online again, the checkout station is switched back to normal mode and the apple takes over the information desk's port for dumping, rendering that terminal inoperative. dumping continues around the clock until all transactions have been processed from both apples. normal activities proceed at all other terminals. diskettes are dumped in chronological order. as the dumping process operates, a file of transactions eliciting error or exception messages from the libs 100 is created on the apple diskette. this file is available for attention at a later time for manual entry into the database. the chief asset of the dumping process is the accuracy achieved by automatic inputting. when we used paper and pencil, not only was the original writing time consuming, but manual data entry was difficult because of illegible handwriting, inaccurate transcription of the numbers, inaccurate inputting into the database, and lack of available personnel for the job. the cti system resolves all of these difficulties, but a price is paid in the loss of the dumping terminal's services. the public may be less disturbed if a terminal in a nonpublic area is used. but to the department involved, access to the database is a central part of their work and its loss severely limits their output. in fact, dependence on the automated circulation system by all departments in the library has been swift and universal even though we originally assumed the terminals outside the circulation department would be used sparingly. plans are being made to store personnel records in machine-readable form on diskettes. other developments are being put on a back burner until we have less frequent communications 299 need for the apples as backups. however, levels, great neck library's youth department, has several apples of its own on which budding "computerniks" practice their art. for them there are few limits to possible applications-perhaps only the outermost boundaries of imagination. reference 1. joseph covino and sheila intner, "an informal survey of the cti computer backup

period of computer-to-computer communication; we now appear to have reached the second stage of development. today more than seventy publishers are equipped to receive computer tape orders and input them directly to their order fulfillment systems; twenty-six publishers can produce computer invoices and credits for their customers; six are capable of sending monthly updating information about titles, prices, publication dates, and books declared out of print. all of this, however, is based on a system through which computer tapes are sent from buyer to seller and back via the united states mail. the next stepcomputer-to-terminal or computer-tocomputer communication-is just around the corner. historical perspective how did this happen? it started in september 1974 when dewitt c. ("bud") baker, newly appointed president of the baker & taylor company, envisioned the savings his company could find if their customers provided the international standard book number (isbn) on their orders. he also believed that the volume of paper created by the computer was expensive and time-consuming for publishers to handle. 166 book reviews proceedings of the 1968 clinic on library applications of data processing, edited by dewey e. carroll. urbana : university of illinois, 1969. 235 pp. $3.00. for all except inveterate institute participants, it must be difficult to decide to spend yet another week listening to a widely mixed series of papers and discussions on data processing in libraries, in the hope of finding something new or useful. to attract a wide audience, the offerings tend to range from simple introductions to technical discussions of specific programs or projects. the value of gathering the papers of such institutes into volumes of proceedings is questionable. material from the introductory papers would certainly find greater use in a comprehensive monograph, while the papers which report new developments or technical problems would have a better chance of reaching their proper audiences if published in journals. the repetitive "how-we-did-it" reports might best be left unpublished. the proceedings of the 1968 illinois clinic does have a number of articles which deserve wide readership. frederick g. kilgour's paper on initial system design for the ohio college library center is excellent, not so much for solutions, but because he raises the questions on the purpose of college libraries and the nature of regional systems which need to be raised before embarking on design. those who have had experience with automated operations will appreciate lawrence auld's listing of ten categories of library automation failure. (he omits one of the most common-lack of computer stability. ) a technical article of considerable interest is alan r. benenfeld's paper on generation and encoding of the data base for intrex. those looking for reports of successful computer applications may find useful information in the papers by robert hamilton, of the illinois state library, on circulation; by james w. thomson and robert h. muller, of the university of michigan, on the u. of m. order system; by michael m. reynolds, of indiana university, on centralized technical processing for the university's regional campus libraries; by john p. kennedy, of georgia tech, on production of catalog cards; and by robert k. kozlow, of the university of illinois, on a computer-produced serials list. melvin ]. voigt book reviews 167 planning library services. proceedings of a research seminar held at the university of lancaster, 9-11 july, 1969. edited by a. graham mackenzie and ian m. stuart. lancaster, england: university of lancaster library, 1969. 30 shillings. this volume offers fifteen papers presented in six sessions; each session had one or more papers and some discussion. the papers range from very general mathematical models to local problems of british legal codes and re-organization of local governments. the first session introduces the problems and some theoretical notions of how to deal with them. the next three sessions deal with analysis techniques. morely introduces some simple techniques of maximizing benefits for given resources. brookes presents a good quick introduction to statistics and distributions which occur frequently in information science. leimkuhler develops cost models for storage policies and woodburn analyzes the costs in heirarchical library systems. the mathematics in these latter papers, although not difficult, will probably put off a good many librarians and administrators. both are practitioners and impressed by results, not complex models; the equations developed by leimkuhler or woodburn are probably too complex to be successfully used by most librarians. this might reflect the state of the librarian and not of the art, however, to quote cloote (from the paper by duchesne) : "with only a very few notable exceptions, successful models have been so simple that an operational research specialist would disown them." the fifth session covers data collection and evaluation. duchesne comments on management information systems and operations research for librarians. conventional techniques of data collection are reviewed by ford, including sample forms and a note of warning about too many surveys. in the final session leimkuhler presents an overview which includes several choice comments on progress (or lack of it) in libraries. during the discussion period, mackenzie suggests that libraries should use up to five percent of their budgets for research. this reviewer feels that unless this suggestion is taken more seriously, most of the theory will never find an application. these proceedings would make an excellent companion to burkhalter's case studies in library systems analysis as more theoretically oriented readings for a course operations research or administration in librarianship. some of the techniques presented could be adapted for immediate application in analyzing present systems. thus this collection of papers can be useful to both student and practitioner interested in research and development of library systems. arvo tars 168 journal of library automation vol. 3/2 june 1970 libraries at large, edited by douglas m. knight and e. shepley nourse. new york: r. r. bowker, 1969. 664 p. $14.95. libraries at large is based on the materials which the national advisory commission on libraries employed in its deliberations. the commission appraised the adequacy of libraries and made recommendations designed "to ensure an effective, efficient library system for the nation." these materials are also useful to those engaged in the enrichment of present library programs and to those developing new library projects. the materials consist of papers and reports written for the commission and include essays, original investigations, and literature reviews, as well as reprints of material that has appeared elsewhere. some papers are of top quality; some are poor. nevertheless, the appearance of these materials in one volume adds a convenient source of information that will be useful to librarians for years to come. approximately half the book is devoted to problems related to the use of libraries and to the users of libraries. the second half contains discussions of government relationships of libraries and a series of useful appendixes. perhaps the most novel section of the book is william j. baumors "the cost of library and informational services." this study investigates the economics of libraries in depth and the results are of great interest. this chapter on economics contains new material and brings together that which existed heretofore, so that it constitutes the major resource on library economics. this chapter alone is so valuable as to justify the recommendation that all libraries and most librarians should acquire libraries at large. the section on copyright is equally important, for it brings together data on a topic possessing cataclysmic potentials for librarianship. verner clapp's "copyright: a librarian's view" is the best statement that has appeared on the subject, and it is hoped that clapp's dissertation will awaken librarians to the peril that confronts them. on the other hand, the chapter entitled "some problems and potentials of technology as applied to library informational services" is somewhat less than satisfying. the section starts off with mathews and brown's "research libraries and the new technology," which originally appeared in on research libraries. it is still an inadequate exposition. there follows a reprint of "the impact of technology on the library building," which educational facilities laboratories published in 1967. the statement is adequate, but more useful information exists. the last section of the chapter is a study, "technology in libraries," which the system development corporation produced. this paper is a useful review of technologies employed by libraries and recommends five important network and systems projects to be undertaken. the chapters on government relationships include discussions of those book reviews 169 with the federal government and those at local, state and regional levels. germaine krettek and eileen d. cooke have provided a worthwhile appendix listing and abstracting library-related legislation at the national level. libraries at large is indeed a resource book, and those papers containing original investigations and literature reviews are of such high quality as to insure usefulness of this work to all thoughtful librarians. frederick g. kilgour computers and their potential applications in museums. a conference sponsored by the metropolitan museum of art. new york: arno press, 1968. 402 pp. $12.50. computers and their potential applications in museums contains the published proceedings of a conference which was held in new york, 1968. sponsored by the metropolitan museum of art and supported by ibm, the conference was another attempt to involve art and related fields in computer technology. this book covers a broad range of issues and problems from information retrieval to creativity. experts from museums, educators, librarians and computer specialists discussed the possible uses and the implications of computers for the museum field. the diversity of the participants seems to represent the components of an exceedingly complex problem which is as monumental as the museum field itself. as an overall document it gives evidence of concern and insight into the many technical problems which some researchers have encountered. in many instances the non-technical experts were too global in their thinking, while the technologists were too local in their area of concern to communicate to anyone but technologists. this disparity between approaches, with the obvious difficulties presented, is a typical one whenever non-technical groups attempt to make use of computer technology. an ambitious conference in scope, there were excellent participants and several of the papers were stimulating and provocative. the interaction among the people who attended the conference may have been useful and it may have generated important ideas. for a reader of the published proceedings one wishes there had been a final chapter which could have provided some guidelines for research and education in this field. there was an opportunity for the organizers of the conference or a small group of the participants to summarize the problems and to give some direction to solutions. several years and many conferences later we in the humanities have made little progress in use of the computer. it seems that we are still better at rhetoric than at problem solving. charles csuri 170 journal of library automation vol. 3/2 june 1970 books for junior college libraries. pirie, james w., comp. chicago: american library assoc., 1969. 452 pp. $35.00. during the recent period of rapid growth and development of junior and community colleges, a bibliographic guideline has been long awaited. james w. pirie's books for junior college libraries, with its healthy potential for developing many basic collections and extending and updating others, fills that void. though it does not boast to be the single ideal bibliographic tool, it is a welcome addition to, (and perhaps replacement for some of) its predecessors-frank bertalan's books for junior college libraries; charles l. trinkner's basic books for junior college libraries; hester hohman's readers adviser; helen wheeler's a basic book collection for the community college library; bro dart foundation's the junior college library collection~ edited by dr. bertalan; and the ever-present subject guide to books in print and books in print, from bowker. books for junior college libraries represents the cooperative efforts of some 300 expert consultants-subject specialists, faculty members and librarians-charged with the responsibility of producing a publication to serve as a book selection guide for new or established junior and community college libraries. approximately 20,000 titles are arranged by subject, broadly interpreted; with entries consisting of author, title, subtitle, edition; if other than the first, publisher, and place of publication, date, pagination, price and l.c. number. easy access is provided by the inclusion of an author and subject index. a comparative "table of subject coverage" appearing in the preface, tabulating the percentage of subject distribution to total volume for the lamount, michigan, and the more recent books for college libraries lists, indicates that books for junior college libraries maintains a comparable subject percentage distribution to total volume. only book titles have been included; foreign entries have been limited to a few major works, and out-of-print titles, in favor of titles readily available. paperbacks were listed, in the absence of card copy. though limited in its coverage of terminal and vocational courses, with emphasis toward the transfer or liberal arts program, books for junior college libraries does embrace all fields of knowledge that tend to be challenging and useful for the general education programs. it has been endorsed by the joint committee on junior colleges of aajc, ala, and the junior college section of acrl, and moves toward the recommendations of the ala standards for junior college libraries. this bibliographic guideline for junior college libraries should be welcomed by public schools as well as junior and community colleges for its assistance in developing new collections, as well as expanding and updating old collections, with quantity, quality, and economy working together. ]ames i. richey book reviews 171 agricultural sciences information network development plan. educom research report, august 1969. 74 pp. the national agricultural library wants to implement its old plan of an agricultural science information network "based on the assumption that the land-grant libraries in the states are the natural nodes to this network." educom undertook a study which was submitted to and discussed by a symposium held in washington, d. c., on february 10-12, 1970, with the participation of all agricultural libraries interested in "new and improved ways of exchanging information in support of agricultural research and education." the goal is "to develop a long-range plan for strengthening information, communication, and exchange among the libraries of land-grant institutions and the nal." according to the report, the network concept would constitute a "network of networks" and three basic components are envisioned: 1) land-grant libraries, 2) information analysis centers, and 3) telecommunications. all these components have their own aims and objectives described in this report. "nal's first course of action in the establishment of a system of information analysis centers is to develop a directory of existing analysis centers of interest to the agricultural community. the directory should be supported with a catalog detailing the services and products offered by these centers. nal should then establish cooperative agreements with these centers which would make them responsive to the needs of the users of the agricultural sciences information network. this should be supported with the installation of communications equipment to encourage and facilitate the use of a center." no doubt, the participants of the symposium will have thoroughly investigated and discussed this plan with serious consideration to its practical implementation. a new approach and improvement of information exchange is not only a necessity, but also long overdue, for those in agriculture. this information development plan would provide service for research workers at the experiment stations, scientists and teachers at the colleges, agricultural extension people at the land-grant institutions, and, last but not least, for the farmers who provide us with food and fibers in order to bring a fuller and better life on the farm and in rural and city homes. a detailed analysis of the performance, an evaluation and revision of this gigantic scientific information system, can only be made after it has been in operation for a few years. it is very promising that the national agricultural library-among its many objectives-has again taken the initiative. john de gara 172 journal of library automation vol. 3/2 june, 1970 cornell university libraries. manual of cataloging procedures. 2d ed. ithaca, n.y. : cornell university libraries, 1969. $18.00. editor robert b. slocum and his associates have produced a valuable manual useful to catalogers and persons involved in the administration of policies and procedures in technical services. as stated in the preface the manual is a supplement, not a substitute, for the anglo-american cataloging rules and its predecessors, lc list of subject headings and the lc classification schedules. the following directive is basic: "the revisers are always open for consultation on particularly difficult problems, but it must be assumed that a professional cataloger will have a thorough knowledge of the basic tools of his profession. . . . if this knowledge is in any way lacking, the cataloger has the obvious responsibility of acquiring it through diligent study and experience. he should not come to the reviser with questions whose answers are available in the aforementioned tools and in this manual." the format is loose-leaf, so that additions and revisions may be made easily to reflect new developments and techniques. the sections include pre-cataloging procedures; general cataloging and classification procedures; recataloging and reclassification; cornell university college and department libraries-special collections and special catalogs; . . . serials and binding department; files and filing; typing, card production, book preparation; statistics; appendix (including abbreviations, romanization tables, etc. ) ; and index. the procedures and practices described are those adopted by a research library "conscious of the need for both quality and quantity in the work of its staff." this publication, weighing five pounds, is a great achievement and with its full index an indispensable contribution to the collection of worthwhile cataloging manuals. descriptions of local procedures may seem detailed but basic principles and policies are well covered. the final touch is the inclusion of a catalog card for the manual! margaret oldfather lib-mocs-kmc364-20131012113301 202 journal of library automation vol. 14/3 september 1981 rlin system scheduled to be operational this summer. the proposed test will involve eight members of the reference stafffour from each departmentwho will be trained to search on oclc and rlin. those selected will include both librarians and library assistants who regularly provide reference assistance. the results obtained from such a representative group will better enable us to assess the impact on the whole reference staff should we later decide to fully implement the service. they will be the only ones involved in sampling questions and conducting comparative searches. the test will have two components, the first of which will be a twenty-week period to collect at least 400 sample questions. during their regularly scheduled reference hours, the eight specially trained librarians 'will collect samples of reference requests for materials that, based on the information initially given by the patron, cannot be identified in the card catalog. after checking the catalog, the librarian will then complete the top portion of a two-page selfcarbon form with all of the information that is known about the requested item. then, at regular intervals during the semester, the pages of each form will be separated and distributed to other members of the test staff for batch-mode searching. the manual oclc and rlin searching for each query will be done by different staff members to eliminate crossover effects. each request will be searched on both oclc and rlin with the following information being recorded: 1. date of the material requested (if known). 2. type of material (e.g. , conference proceeding) . 3. amount of time required to do the search. 4. success or failure of the search. this information will then be cumulated in a statistical table, and the results of each search will be keypunched for computerized analysis using the bmdp (biomedical computer programs) statistical package to determine whether or not effectiveness and efficiency have been improved significantly. in addition , on twenty-four randomly selected days during the semester the trained searchers will count the total number of questions received by them on that day that would have been appropriate to search on rlin or oclc. by using these data it will be possible to extrapolate the potential usefulness of the systems for the entire semester. the second component of the test will be a two-week real-life test during which all questions requiring further verification would be searched immediately on rlin, oclc, and in the appropriate printed sources to compare time required, success rate, and type of material requested. this sort of test would permit the searcher to continue to negotiate with the patron as the search progressed, which is the usual situation. also, this would provide the only opportunity to have the patron judge the value of subject searches done on rlin. if funding is received, preliminary results should be available in early 1982. anyone conducting similar or otherwise relevant studies is asked to contact the author. replicating the washington library network computer system software thomas p. brown: manager of computer services, and raymond deb use: manager of development and library services, washington library network, olympia. the washington library network (wln) computer system supports shared cataloging and catalog maintenance, retrospective conversion, reference, com catalog production, acquisitions, and accounting functions for libraries operating within a network. the system offers both full marc and brief catalog records as well as linked authority control for all traced headings. it contains more than 250,000 lines of pli 1 and ibm bal code in more than 1,100 program modules and runs on ibm or ibm-compatible hardware with ibm operating systems (mvs ,os/vsl). all database management functions are provided by ada:bas, a product of software a.g. of north america. the online system runs under cics/vs 1.5. a set of assembler codes called the tp monitor interface defines a standard service interface between the applications programs and the tp monitor. this allows easy upgrade to different tp monitors and convenient points for collecting performance statistics. the majority of the bibliographic subsystem updating is done in batch mode to conserve online resources. a new version of the system with interactive updating is currently being planned, for use in special environments. the applications software was designed and implemented with a number of important conventions: 1. top-down design. 2. standard use of ibm environments. 3. structured coding techniques. 4. interfaces to a database management system (adabas) and teleprocessing monitor (currently cics). 5. stand;ud naming and formatting. 6. use of a standard set of data structures and assembler subroutines to manipulate data. 7. identification of maintenance changes in source programs. in addition, programming for the online functions meets other conditions: 1. load modules less than 20k bytes. 2. no pl/1 run-time subroutines. 3. reentrant coding. 4. standard services for the tp monitor interface. 5. applications are kept as terminal independent a~ possible, with the tp monitor interface performing input and output translations. replication a system with these characteristics, even though large, can easily be transported to a different site. while wln was not designed with multiple replications in mind, a policy decision made by the network a few years ago made replication an attractive possibility. recognizing that it had a capability that would be highly competitive with other online shared bibliographic services, wln expanded its service area beyond the state of washington. it set limits to its expansion, however, having determined that it would remain a small, responsive organicommunications 203 zation providing what it hoped would be superior service to its participating libraries. having set such limits, however, created two impediments to its achieving superior service: wln would have a smaller base of libraries from which its participants could obtain the benefits of shared cataloging, and there would not be the fiscal resources necessary to support a large continuing development effort. both would penalize libraries for joining wln, the first with a lower hit rate against the database and the second with fewer added capabilities. replication provided a possible answer to both of these problems, as well as a potential source of income. in its software license agreements, wln asks the licensee to agree to bibliographic data sharing. all cataloging done by a licensee or its participants would thus be available for loading on wln's own database; likewise, all wln participant cataloging will be made available to the licensee. wln, at least, would accept catalog records only from libraries that follow its bibliographic standards; that is, the standards of the library of congress. currently this sharing is accomplished via magnetic tape, but in the future, online record interchange may be possible, given wln's current work in this area. wln also explicitly asks in its software license agreements that the replicating institution carry out an organized program of development to meet the latter's particular needs. such development is monitored by wln in order that redundant work is not undertaken and to ensure that the various efforts relate coherently. there is a built-in constraint upon major modification andredesign: wln is packaging enhancements and changes into periodic releases of the source code and requiring that the replicants install these releases within twelve months of the date issued. because of the interest in shared development and because wln itself is not in a position to provide first-level program maintenance, the system is distributed in source-code form. the initial installation, however, is of load modules (programs in a form efficiently read and executed by machine), allowing immediate testing of the system's capabilities in its new environ204 journal of library automation vol. 14/3 september 1981 ment. wln is currently negotiating a contract with a new firm, biblio-techniques, that will offer a more nearly turnkey version of wln, packaged with adabas and software a.g.'s tp monitor, complete, and, if necessary, with the required hardware. national lffirary of australia the first replication of the system was made at the national library of australia (nla) in cranberra in early 1979. nla had its own ibm 370/148 and an established data processing staff. adabas had been installed prior to the arrival of wln's installation consultant. minor changes are necessary in cics to support dedicated wln terminals, and these were quickly made and the system was up within days. further work allowed searching on the system from the library's 3270 terminals. after a couple of weeks of shakedown, a wln staff member spent about two weeks training nla staff in the use of the system. it has been in full production for in-house production cataloging for more than a year now, and this spring is being extended to other libraries around the country on a pilot basis, testing the concept of the newly defined australian bibliographic network (abn). nla has replaced the 370/l48 with a larger machine. university of illinois the second installation occurred earlier this year at the university of illinois, where the system was obtained to carry out a pilot project in which the urbana campus and the river bend library system will use it as an online public-access catalog in conjunction with the lcs circulation system. again, load modules were installed and the system was up within a few days, running on the university's administrative computer at the chicago circle campus. illinois staff have had some difficulties in recompiling all of the source code, but these problems are being worked out. wln will warrant that the source code supplied corresponds to the load modules it installs. the system as presently distributed by wln can in no way be considered turnkey. local computer operations or jcl requirements as well as differing levels of staff expertise can create problems. furthermore, wln handles source management through wylbur, a text-editing system, and this is not included with the wln software. the module descriptions, grogramming language, mode, link-edit information, etc., maintained through this facility are supplied, however. either a test or, if contracted for, a full database is also supplied. wln has had some difficulties in creating a valid test database for illinois, but has now defined procedures to better control the process. wln has distributed its second release to australia as a full source update identical to what was installed at illinois. in the future only the source changes in standard ibm iebupdte form will be supplied to replication sites. this will better enable these sites to integrate the new version into theirs. other sites the university of missouri is likely to be the third replicant of the system, since it has just selected wln as the basis for its online catalog system . installation is planned before the end of 1981. the national library of new zealand has also indicated that it intends to purchase the system. the southeastern library network (solinet) has obtained the system in order to convert it to a burroughs facility. while this is a software license, it is not a replication. theresulting system, however, would be available from wln for installation on burroughs equipment. wln has not implemented data sharing with australia, but is testing the loading of illinois data into its bibliographic file. wln libraries should see illinois records on a regular basis by late summer of 1981. similar arrangements will be made with missouri and solinet. shared development has gotten off to a start with the national library of australia having done the work necessary to add the ibm 3270 type of terminal to those that can support cataloging input and edit on wln. illinois will be undertaking the development of enhancements to make the system easier to use as a public online catalog, in addition to other possible areas of concern. wln, of course, continues its in-house development, which has recently seen the implementation of a new batch retrospectiveconversion subsystem, and added com catalog options and online authority verification during input/edit. while not the only bibliographic system to be successfully replicated, the wln computer system is becoming the most systematically replicated main-frame facility, with a broad range of future possibilities, including that of a truly turnkey system. wln's experience indicates that, if a system is designed for ease of maintenance at perhaps some sacrifice of efficiency, it will be readily transportable and allow others to obtain the benefits of a highly sophisticated bibliographic capability without the everincreasing cost of original development and, more importantly, without having to support the ongoing maintenance of a unique system. a general planning methodology for automation richard w. meyer, beth ann reuland, francisco m. diaz, and frances colburn: clemson university, clemson, south carolina. introduction a workable planning methodology is the logical starting place for the successful implementation of automation in libraries. an automation plan may develop on the basis of an informal arrangement or from the efforts of one individual, but just as often, automation plans are developed by committees. an automation planning committee must determine and execute some kind of planning methodology and is more likely to be successful if it starts with clear guidelines, good leadership, and a thoroughly proven approach. as a summary review of the literature will bear out, many libraries have developed their own planning techniques inhouse. some of these, which are addressed to the issues of cataloging rule changes and public-access catalogs, have been very well thought out. 1 however, these techniques are generally not directed to planning for communications 205 library-wide automation, and are usually designed to meet the specific needs of an individual library. although the pattern for these studies is often similar, they do not seem to be based upon any general automation design methodology. neither, in addition, does there seem to be a general methodology available through any external library agency. the office of library management studies of the association of research libraries has developed a number of programs designed to assist libraries with their planning efforts, some of which appear to be useful in automation development. 2 but for many libraries, these programs may be too broad, too time-consuming or too expensive. as an alternative, some libraries will need to look elsewhere for a general automation planning methodology. this problem was addressed by the administration of the clemson library, and was resolved in a unique way. background the robert muldrow cooper library of clemson university has the responsibility of acquiring, preserving, and making available for use the many materials needed by faculty and students in their research and instructional efforts. at a typical landgrant institution like clemson, the amount of scholarly publishing and the pressure to develop research proposals has risen sharply in recent years. the increased needs of users working with an expanding and diversified collection have resulted in a doubling of circulation activity, and have required the growth of library staff by 70 percent over the last decade. furthermore, acquisition, processing, and access problems are compounded by the high inflation rate of materials, particularly serial publications, and manpower costs. even though user demands heavily burdened the traditional manual systems, the extent of library automation at clemson had been limited to a batch circulation system, a simple serials-listing capability, and the use of bibliographic utilities. although it had been generally accepted for some time that the acquisitions and fund-control functions at clemson were in need of automation, no concrete approach to developpublic libraries leading the way reorienting collection analysis cost-effective item-level analysis and

r.hanney@sjcpl.org) is staff development coordinator, st. joe county (indiana) public library. © 2023. abstract in public libraries, especially those in rural settings, it is important that every dime of library funding is leveraged effectively into serving the community. as part of a year-long project beginning in january 2023, we are evaluating item-level cost-effectiveness for each circulating item housed at the public library in lakeville, indiana. through the use of big(ish) data, some custom python scripting, and machine learning algorithms we hope to answer: how much money is saved by library patrons through their use of the public library's physical collection? how much money is saved by the community through the operation of a public library based on the use of the circulating collection? and are there any non-obvious traits which make an item or title a more or less cost-effective circulating asset? in this column, i will describe the scripts, share initial findings, discuss challenges, and investigate next steps. introduction there is so much to be said about the value public libraries bring to the communities they serve. this column is not going to investigate the worth of programs or experiences, the social interactions taking place, the knowledge or education gained by patrons, or the many other benefits that endure because of the existence of public libraries. instead, this column will discuss the dollars and cents value that public libraries bring to their community using circulating collections. by using data available through the library's integrated library system (ils), i examine how cost-effective each item is throughout any given month, quarter, or year, and what, if anything, makes an item more or less cost effective. about the community this project focused on a public library branch located in lakeville, indiana, one of the ten locations operated by the st. joe county public library system. lakeville is a rural farming town with a population of 878 people. what prompted the work? during the past few years, the st. joe county public library had received some concern from the community regarding the amount of money being used toward library operations. these concerns were spurred by the renovation of the largest location in downtown south bend, which took two years and cost an estimated $38 million to complete. with the added financial pressure on households brought on by the covid-19 pandemic and the marked increase in inflation, some patrons were beginning to voice concerns about the financial benefit of public libraries. mailto:r.hanney@sjcpl.org information technology and libraries december 2023 public libraries leading the way: reorienting collection analysis 2 hanney part i: the money saved with the goal of determining the financial benefits of the library's collection, i took the first step towards devising an effective method to best measure the value of any given item in the library's collection at the branch. the cost of the item and the number of times it was checked out was reviewed. while not a perfect system, this method provides the total amount of money saved by library patrons who check out the material rather than purchase it for themselves. the formula was the following: money_saved = times_circulated * item_cost table 1 shows how the amount of money saved by patrons, without accounting for operating expenses, was calculated. the init chkout and secd chkout fields relate to the first and second time the data was harvested from the library’s database. the difference of these two variables yields the number of times the item was checked out within a certain time period. in this instance, it was a month. each of the items above are from a different collection, a non-fiction book, holiday dvd, picture book, and a beginner reader. table 1. barcode init chkout secd chkout tot chkout price saved 3 1986 03488 2657 50 51 1 $19.95 $19.95 3 1986 03656

saved the community. uncovering this information was much more difficult considering the costs associated with the operation of the library and that not all operating costs are directly focused on the collection. for the purposes of this project, the cost of one full-time circulation assistant per 10,000 items, building and utility costs, subscription service costs necessary for collection management, and the cost of new materials were used to calculate operating expenses. the following formula was used: money_saved = (times_circulated * item_cost) – (operating_expenses / number_of_items) while this method is not a perfect way of looking at the value of each item based on the cost to the community, it provides a framework for consistently measuring this metric, which met the needs for this evaluation. part ii: methodology and data analysis to figure out answers to the two questions (how much money is saved by library patrons through their use of the public library's physical collection? how much money is saved by the community through the operation of a public library based on the use of the circulating collection?), i harvested and analyzed select data from the library's ils to gain insight into what makes each item more or less cost effective. at the beginning of each month, i exported the following itemlevel data from the ils: information technology and libraries december 2023 public libraries leading the way: reorienting collection analysis 3 hanney • item barcode or specific identifier • total number of checkouts throughout the life of the item • initial cost of the item at time of purchase • item’s collection area (children's picture books, adult mystery, etc.) • call number of the item • publication statement (marc 260: publisher, publication date, region of publication) • subject added entries (marc 650: common search terms linking to a controlled vocabulary) • index terms for genre/form (marc 655: words or phrases used to aid in the discovery of the item on the library's online public access catalog) table 2 shows example data harvested from the ils. table 2. sample data harvested from the library’s ils.

12,000 rows, one row for each item in the lakeville branch library’s collection. information technology and libraries december 2023 public libraries leading the way: reorienting collection analysis 4 hanney part iii: the scripts working with such large datasets by hand would have been nearly impossible due to the time it would have taken and would have likely resulted in the presence of human errors. for these reasons, i wrote python scripts to handle the data within these datasets. these scripts generally fall into two categories: data pre-processing and data analysis. scripts are available in github at https://www.github.com/sardinedude1/ceila. the scripts contained within the data pre-processing category prepare the data to be analyzed and include format manipulation, concatenation, and the generation of training data. the scripts which fall under the data analysis category generate useful information in understanding the pre-processed data. one of these scripts consists of a multi-input neural network model that combines text and numeric inputs, concatenation layers, and a dense output layer for classification. in other words, it is a predictive model which uses harvested item-level data and predicts whether the item would be cost effective or not. the neural network uses the item's collection, the publication statement, the number of subject added entries, and the cost of the item to predict the value rating of the item on a scale of 1 to 3, with 1 being not cost effective and 3 being cost effective. part iv: initial findings money saved on average, patrons of the public library in lakeville, indiana collectively saved approximately $18,500 each month by checking items out rather than purchasing them. after accounting for operating expenses, the community saved on average an estimated $8,500 each month. in st. joseph county, the library is funded mainly by property taxes. the average lakeville household pays $3,471.40 per year in property taxes. however, only a small portion of those tax dollars ever reach the library. these funds amount to an estimated $16 per month per resident. after library operating expenses are considered, over half of the taxpayer’s obligation is recouped through their use of the circulating collection. machine learning once complete, the neural network was able to provide accurate predictions about an item's costeffectiveness, with an average accuracy rating of 92% . this rating was determined by separating the available data into training data (90% of the dataset) and testing data (10% of the dataset). once the model was trained using the training data, it was asked to make predictions about the testing data it was not trained on. for example, if a dataset was 12,000 items, the neural network would be trained on 10,800 items. when asked to predict whether or not an item was costeffective on the remaining 1,200, it got 1,104 predictions correct. after an investigation into the internal architecture of the trained model, i discovered that the most important feature in predicting if an item is more or less cost effective is the publication statement. however, the number of subject fields was also highly weighted and was only slightly less important when forming predictions. the third most important feature was the genre or collection to which the item belongs. which was still weighted more than twice as important as the cost of the item. https://www.github.com/sardinedude1/ceila information technology and libraries december 2023 public libraries leading the way: reorienting collection analysis 5 hanney these preliminary findings are based on initial results of the predictive model. more work is required to determine if this is a viable means of predicting an item’s cost effectiveness using only these four variables. part v: challenges and limitations several challenges were encountered throughout the course of this project, including the availability of data, the amount of time needed to pre-process data and train an artificial neural network on non-specialized equipment, and my own knowledge of artificial intelligence and neural networks. the infrastructure for data analysis at the item-level was not something our library had given a lot of thought to before this project. there were no formal guidelines or staff training on how to analyze this kind of circulation data or even where to find this data. however, beginning with the ils user manual and ending with a series of long conversations with the database librarian, a temporary framework was established, and i was able to get the data needed. once the data was acquired, it needed to be processed. it took approximately 20 minutes of processing time to prepare a single dataset of about 12,000 lines. this does not include the time it takes to check for errors in preprocessing scripts, the training of the neural network, or backing up the data. this process could have been sped up with higher quality or specialized equipment, but there was none available, so i made do with the resources i had on hand. the last barrier encountered during this project was the limited knowledge of neural networks and artificial intelligence model architecture. it turns out, being a public librarian does not prime someone for an easy foray into the world of ai development or even computer programming. however, with much time and energy, a functional neural network was born after hours and hours of testing and troubleshooting. part vi: conclusion and next steps i was pleasantly surprised to discover the initial amount of money saved by patrons who check items out at the library rather than purchasing the items for themselves. this metric could be used to aid in demonstrating the dollar and cents value library users get access to through their local library. the findings surrounding the money saved by the community, albeit an estimated amount, was also encouraging. with this metric in mind, perhaps steps could be taken to increase the monetary value the library presents to the community through its circulating collection. while public libraries are so much more than the materials they make available to their patrons, continuing to provide materials that aid in the economic support of the community should be of some consideration. finally, after analyzing the results from the neural network, some non-obvious traits were discovered to have an impact on the cost-effectiveness of items. the publication statement being the highest weighted feature in forming a prediction was quite striking. this suggests that the marc 260 field has the highest influence on an item’s circulation, and by extension its costeffectiveness, out of the four inputs investigated. it was equally remarkable that the cost of the item had the least amount of influence in making a prediction. this seems to indicate that the cost of a circulating object holds little influence on how well the item will circulate. information technology and libraries december 2023 public libraries leading the way: reorienting collection analysis 6 hanney while a more comprehensive look at the relationships between item-level data and its effects on circulation is needed before implementing this neural network as a collection development tool, the information gained from looking at how much money patrons and the community save by using the library is certainly usable now. in fact, it just might make it into the next library newsletter. 121 n ews and announcements redi or not . .. "public libraries and the remote electronic delivery of information (redi)," a working meeting, was held in columbus, ohio, on monday and tuesday, march 23 and 24, 1981. the meeting, jointly sponsored by the public library of columbus and franklin county (ohio) and oclc, inc., considered the issues that public libraries must examine before becoming involved in electronic information services . subjects explored included technology, communications, information providers, information users , social implications, and financial, legal, and regulatory responsibilities. tom harnish, program dir e ctor of oclc' s home delivery of library services program, was moderator of the twoday event. participants at the conference represented a variety of public libraries from throughout the u.s., including new york, georgia, texas, california, colorado, and illinois. don hammer represented lita at the meeting; mary jo lynch of the ala office for research also attended . "geographic distances, " said harnish, "were the only points of separation among the meeting participants . there was an overwhelming agreement on the concerns for the future of libraries and universal access to information in the electronic age . " on the second day of the conference it became apparent that the redi agenda could not be properly dealt with in two days. "we need an organization which will address these issues on an ongoing basis," said richard sweeney, executive director of plcfc . "librarians at the conference agreed to promote and lead the development of the electronic library . to that end, this group is seeking recognition by ala as a membership initiative group with a special interest in the electronic library." the group's founders prepared the following mission statement for the membership initiative group: to ensure that information delivered electronically remains accessible to the general public, the electronic library association shall promote participation and leadership in the remote electronic delivery of information* (redi) by publicly supported libraries and nonprofit organizations . goals of the organization are to: • identify services and information that are best suited to remote electronic delivery; • plan , fund, and develop working demonstrations of library redi services ; • communicate the availability of electronic library services to the user community; · • inform the library profession of trends, specific events , and future directions of redi; • create coalitions with organizations in allied fields ·of interest. public libraries and nonprofit organizations with information interests, such as information and referral groups, are invited to join the electronic library association . the group plans to meet at the ala annual conference in san francisco. meeting details will be announced as soon as they are available . it was the goal of the "public libraries and the remote electronic delivery of information " meeting to provide th e fram e work within which to address the myriad issues in redi. the electronic library group will validate the role of libraries in technology .... redi or not here we come. *information delivered electronically where and when it is needed, in the library and elsewhere (home/office/off-site). 122 journal of library automation vol. 14/2 june 1981 arl adopts plan for improving access to microforms a plan aimed at improving bibliographic access to materials in microform by building a nationwide database of machinereadable records for individual titles in microform sets was approved in principle by the arl board of directors on january 30, 1981. the plan concentrates on monograph collections, and is aimed at providing records for individual titles in both current and retrospective sets. records add~d to the database will also aid cooperative efforts in preservation microfilming. elements of the plan include: • inputting of records conforming to accepted north american standards to the major bibliographic utilities by libraries and microform publishers; • d~ve_lopment of "profile matching" by the b1blwgraphic utilities permitting the cataloging of all individual titles in a series or microform collection with single operation; • cooperative cataloging of current and retrospective microform sets by libraries and publishers; • compensation for publishers who input acceptable bibliographic records to the bibliographic utilities to offset loss of revenue from card set sales. cooperation among libraries publishers, networks, and others ha's been stressed throughout the development of the plan, and initiatives on a number of fronts are necessary and encouraged in order to accomplish the goal of improved bibliographic access to microforms. arl will s_eek outside funding for a program coordmator to facilitate implementation of the elements outlined above, and recruitment for the one-year position will begin short!~ . the coordinator, advised by a committee of librarians (from arl and ~on-arl institutions) and microform publ~shers, will work with libraries, publishers, and the bibliographic utilities to help get the plan off the ground. the plan is the result of a one-year study funded by a grant from the national endowment for the humanities and conducted for arl by richard boss of information systems consultants, inc. during the course of the year, he interviewed librarians , microform publishers, representatives of the bibliographic utilities, and others interested in bibliographic access to microforms, gradually building the plan from elements on which there was agreement and discarding ideas that were not widely accepted. the effort to build a consensus among the various interested parties was aided by the advisory committee, comprising both arl librarians and microform publishers, which assisted and advised throughout the course of the project. arl will publish the study this spring. arl sponsorship of this project and its follow-up reflects the long-standing commitment the association has had to improving access to microforms . two earlier arl studies on improving bibliographic access contributed to the development of standards for descriptive cataloging of microforms, reinforced the importance of microforms for preserving and disseminating scholarly materials, and identified some of the problem areas that the current study has addressed . today, as the amount of materials in microform in arl libraries continues to grow-arl libraries hold more than 146,660,000 units of microform-improving access to these materials has taken on even greater urgency. the association of research libraries is an organization of major research libraries in the united states and canada. members include the larger university libraries, the national libraries of both countries and a number of public and special librar~ ies with substantial research collections . there are at present 111 institutional members . battelle studies using computers to access unpublished technical information engineers may be able to use computers to store, call up, and otherwise display some technical information not currently published in professional journals as a result of a study recently begun by battelle's columbus laboratories. in a four-month study sponsored by the american society of mechanical engineers (asme), battelle researchers are examining ways to use computers as an alternative to publications for communicating with the technical community. asme is a technical and educational organization with a membership of 100,000 individuals, including 17,000 student members. it conducts one of the largest technical publishing operations in the world, which includes codes, stanc dards, and operating principles for industry. according to battelle's gabor j. kovacs, certain types of information traditionally are not covered in monthly or quarterly technical journals, yet they often have widespread appeal among engineers. "recent advances in computer and telecommunications technologies, coupled with rapidly rising publication costs and postal rates, have created an ideal environment for organizations to consider using computers as an alternative mode of communication," kovacs said . "data bases can be used to maintain information that is impractical for conventional publication, and it is now possible to use them for many other types of communication as well." during the study, researchers will determine the feasibility of using a computer database to disseminate to asme members such information as short articles dealing with design and applications data, news and announcements 123 catalog data, and teleconference messages. with the help of the asme, battelle specialists will define the information requirements for such a system. while technology is sufficiently advanced to accommodate virtually any type of information, costs can become prohibitive unless practical compromises are made, kovacs said . as part of the study, battelle researchers also will analyze the costs associated with systems of varying capabilities. researchers then will define several alternative database systems, which will include such attributes as: • online, interactive retrieval features • simple-to-use retrieval language • user-aid features • a minimum of seventy-five simultaneous users • ability to send, store, and broadcast messages • compatibility with a variety of hard copy and crts (cathode ray tube terminals) • sixteen or more hours per day availability to accommodate different time zones • a minimum of thirty-characters-persecond transmission rates two of these alternative system de .signs-one representing a minimum capability and the other a maximum capability-then will be selected for further evaluation by battelle and the asme. measuring the impact of digital heritage collections using google scholar articles measuring the impact of digital heritage collections using google scholar ángel borrego information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.12053 ángel borrego (borrego@ub.edu) is associate professor, universitat de barcelona (spain). abstract this study aimed to measure the impact of digital heritage collections by analysing the citations received in scholarly outputs. google scholar was used to retrieve the scholarly outputs citing memòria digital de catalunya (mdc), a cooperative, open-access repository containing digitized collections related to catalonia and its heritage. the number of documents citing mdc has grown steadily since the creation of the repository in 2006. most citing documents are scholarly outputs in the form of articles, proceedings and monographs, and academic theses and dissertations. citing documents mainly pertain to the humanities and the social sciences and are in local languages. the most cited mdc collection contains digitized ancient catalan periodicals. the study shows that google scholar is a suitable tool for providing evidence of the scholarly impact of digital heritage collections. google scholar indexes the full-text of documents, facilitating the retrieval of citations inserted in the text or in sections that are not the final list of references. it also indexes document types, such as theses and dissertations, which contain a significant share of the citations to digital heritage collections. introduction in recent years, many libraries have been devoting a large amount of resources, in terms of staff, equipment and infrastructure, to digitalize their special collections and to make them available on the web. the european union “has invested €265 million in research and innovation for advanced digitisation technologies, digital curation and innovative cultural projects.”1 in most cases, the purpose of these initiatives is twofold: to facilitate access to scholars, and to the wider public, to rare and important materials, and to enhance long-term preservation. despite the benefits and value derived from these initiatives, there are few examples of evaluation of their impact. much of the existing evidence remains anecdotal and the culture of assessment “has not yet penetrated digitization and digital collection building activities to nearly the same extent as many other areas of research library activity.”2 most previous research aimed at assessing the results of digitalization projects has focused on issues such as interface design, usability or users’ information behaviour, whereas “studies about the impact of digital collections have not been conspicuous in the field.”3 a meta-analysis of 41 evaluations of europeana revealed that system-centered evaluations prevailed over user-centered evaluations and “only a marginal number of studies tried to assess the impact of europeana on different stakeholders.”4 more recently, a survey conducted by liber’s working group on digital humanities and digital cultural heritage showed that “digital humanities work within libraries is currently undergoing limited evaluation,” with over half of the respondents not conducting any mailto:borrego@ub.edu information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 2 specific assessment.5 the report recommended that research libraries should measure their achievements and impact, to not only make decisions, prove success, and support arguments for resources if required, but also to provide new ways for academics to value the library. according to shaw, comprehensive assessment of digital collections requires a combination of methodological approaches, including statistics and surveys, user and usability studies, and webbased analytics.6 the latter would encompass citation analysis, a method that could be employed to assess the reach and impact of digitized collections in a similar fashion to its use as a metric of the impact of scholarly works. unfortunately, citation information for digitized collections is hard to capture due to the lack of specific guidelines in standard citation formats for these materials, resulting in inconsistent citation practices. the impact of digitalization projects is sometimes measured in terms of visiting statistics, which are used as a proxy to evaluate the effectiveness of the resources devoted to digitalizing heritage collections. biswas and marchesoni, at the hunter library, were among the first authors to employ web analytics to obtain usage data from digital collections.7 although enlightening, usage figures alone do not illuminate the reasons for usage and its impact, since download statistics do not indicate whether users find digital collections useful for learning, teaching, research, or leisure purposes. in a different approach, sinn conducted a bibliometric study aimed at determining the relationship between digital resources and historical research.8 she analyzed references and figures in articles published in american historical review to observe how frequently and widely digital collections were used. she found that secondary materials were the most frequently employed digitized resource, with archival materials coming in second place. digital archival materials were more frequently mentioned in figures than in citations, proving the difficulty in compiling citation information for digitized collections. the present study aimed to emulate sinn’s pioneering study on the use of citation analysis to measure the impact of digitized heritage collections, expanding our understanding of how digital heritage collections are used for academic and scholarly purposes. to do this we introduced two changes to sinn’s design related to the population of citing documents and the tool employed to retrieve the citations. first, instead of analyzing the references in a sample of journals in a given field to identify citations to digital collections, we retrieved all the citations to a specific digital collection that was used as a case study. therefore, we did not measure how digital collections are cited in journals in a given discipline, but how scholarly outputs in different formats and disciplines cite a specific digital heritage collection. the collection used as a case study is memòria digital de catalunya (mdc, http://mdc1.csuc.cat/en), a cooperative open-access repository containing digitized collections related to catalonia and its heritage. the project is promoted by the universities of catalonia and the biblioteca de catalunya, with the participation of other catalan institutions. second, we used google scholar to retrieve the citations to mdc. the rationale for this choice was to obtain an accurate picture of the diversity of research outputs and disciplines in which digitized collections are used. previous research has shown google scholar to be reliable and to have good http://mdc1.csuc.cat/en information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 3 coverage of the diversity of disciplines, languages, and document types in the humanities and the social sciences, where usage of heritage collections is expected to be highest.9 the study aimed to address two questions: 1. to what extent are mdc collections being used in the creation of scholarly outputs? 2. is google scholar a useful tool to measure the impact of digital heritage collections? methodology on february 23, 2019, we searched google scholar for documents including a web reference to mdc in the full-text. the server hosting mdc has changed its url several times since the inauguration of the service in 2006, so we used six queries to retrieve as many records as possible: mdc.cbuc.cat, mdc.csuc.cat, mdc1.cbuc.cat, mdc2.cbuc.cat, mdc1.csuc.cat and mdc2.csuc.cat. all queries, except for the last one, retrieved some records, giving a total of 366 results. for each record, we accessed the full-text of the document. at this stage, we removed 42 duplicates, i.e., copies of the same document hosted on two servers that google scholar had not been able to match. additionally, two records were no longer available at the url listed in google scholar and were removed from the analysis, leaving 322 citing documents. in order to download the records, we used the “my library” feature in google scholar. this service allows users to export records in four formats: bibtex, endnote, refman, and csv. exported records had eight fields, although the level of completion was different for each field. “authors” and “title” were provided for all the records, but the level of completion was lower for the “publication” (53 percent), “volume” (24 percent), “number” (33 percent), “pages” (44 percent), “year” (85 percent), and “publisher” (34 percent) fields. in order to analyse the evolution in the number of citations by year of publication, we manually retrieved the year of publication for 46 additional documents, thus covering 99 percent of the records. for each of the 322 citing documents, we searched the full-text for the citation to mdc. however, 48 documents were behind a paywall and we were unable to access them. as a result, the population of citing documents for the second part of the analysis on cited mdc collections was reduced to 274 documents. most citing documents included a single reference to mdc, but, in some cases, the number of citations to mdc was higher, with an extreme case of an analysis of medical cartoons citing 323 resources in mdc. in order to analyse the results, when one document cited different resources in a single mdc collection, we counted this as a single citation. this was, for instance, the case for the medical cartoons example, since all references cited the same magazine. however, when a single document cited different mdc collections we counted as many citations as collections were cited. for instance, if a document cited a digitized resource in a parchment collection plus an article belonging to a collection of digitized magazines, we counted two citations. in total, the 274 citing documents contained 313 citations. citations were made at very different levels. in some cases, authors referred to the whole mdc website, citing the generic url of the platform. in other cases, they cited a specific collection in mdc such as “incunabula” or “manuscripts.” some references cited a certain digitized magazine information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 4 whereas, in other cases, they referred to a specific issue or an individual article in a magazine. additionally, many links to mdc were broken, forcing us to gather much information manually. in order to compare the coverage of google scholar with that of scopus, we also searched scopus using the “reference website” option in the advanced search. this

number of documents citing mdc has grown steadily since its creation in 2006, reaching a maximum of 61 documents published in 2016 citing the repository (see figure 1). figure 1. documents citing mdc by year of publication, january 2006–february 2019 (n = 319). documents citing mdc can be broadly classified into two large categories: published scholarly outputs, such as journal articles, proceedings, or monographs (68 percent of the citing documents), and academic theses and dissertations (25 percent), with the remaining 8 percent of the citing documents including reports, open educational resources (oers), course syllabuses, conferences, etc. (see table 1). information technology and libraries june 2020 measuring the impact of digital heritage collections using google

of the documents citing mdc were journal articles. these articles had been published in 126 different journals. in order to determine the disciplines of the journals citing mdc, we searched for them in ulrich’s periodicals directory. figure 2 shows the subject of the 148 articles published in journals indexed in ulrich’s periodicals directory that we were able to retrieve; the remaining 19 articles had been published in journals not indexed in ulrich’s periodicals directory. figure 2. disciplines of the articles citing mdc (n = 148) as shown in figure 2, half of the articles citing mdc were published in two humanities disciplines: linguistics and literature (26 percent) and history (25 percent). additionally, a third of the articles (34 percent) had been published in journals in different fields in the social sciences and humanities, including education (6 percent), music (4 percent), art (3 percent), religion (2 percent), anthropology (1 percent), philosophy (1 percent), and political science (1 percent), among others. there were also a few cases of citing articles published in journals in the information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 6 experimental, health, and natural sciences (3 percent), usually in studies employing a historical approach to these disciplines. in all cases, the authors of the articles had used mdc as a primary source for their research. finally, 15 percent of the articles citing mdc had been published in library and information science journals. in most cases, these articles had been written by librarians who described the features of mdc to a professional audience in their field. consistent with the high number of outputs in the humanities and the social sciences, most citing documents were in local languages, i.e., 48 percent had a title in catalan and 35 percent in spanish. the remaining outputs were in english (11 percent) or in other languages (7 percent). when we looked at the coverage of the citing journals in scopus, we observed that 37 (29 percent) of the 126 citing journals were indexed by the database. these 37 journals had published 49 articles citing mdc. these results were inconsistent with those obtained when searching scopus for mdc references, when we were able to retrieve just twelve records. we followed up these discrepancies, i.e., the articles published in journals indexed in scopus whose mdc citations were retrieved in google scholar but not in scopus, and in most cases, the reason for the discrepancy was that mdc citations were not in the list of references at the end of the article. the refer ences to mdc were inserted in the text or located in footnotes, annexes, lists of websites, etc. in some cases, mdc was cited in document types not indexed by scopus, such as book reviews. figure 3 shows three examples of these discrepancies, i.e., mdc references cited in articles indexed in scopus but not retrievable when searching the database. in the first example, the reference to mdc was in a footnote but not in the final reference list. in the second example, the reference to mdc was included in a list of “sources” placed before the reference list that starts at the bottom of the image. finally, in the third example, the reference to mdc was included in an annex, but not in the list of references. in all three cases, the articles were indexed in scopus, but the records did not include the references to mdc. conversely, all three documents were retrieved in google scholar since it had indexed the full-text. information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 7 figure 3. examples of mdc citations in

aside scholarly outputs published in the form of journal articles, proceedings or monographs, the second category of mdc-citing documents (25 percent) was that of dissertations and theses. this included dissertations at all academic levels: undergraduate, postgraduate and phd. in nearly all cases, dissertations were hosted in university institutional repositories and belonged to disciplines similar to those recorded for scholarly outputs, such as language and literature or history and, more generally, to the humanities and the social sciences. finally, up to 75 citing documents (8

the citations. these citations, however, were not strictly comparable, since four citations referred to the whole arca collection, 33 citations referred to a specific magazine, six citations referred to a specific issue, and 68 citations referred to a specific article. thirty different digitized magazines were cited. https://doi.org/10.7202/1032404ar information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 9 finally, 135 citations referred to 49 different collections. just three collections received more than ten citations each: a collection of digitized posters from the spanish second republic and civil war (15 citations), a photographic collection of the hiking club of catalonia (11 citations), and a collection of manuscripts from the biblioteca de catalunya (11 citations). discussion and conclusions the results of the study provide evidence of the academic impact of mdc collections among scholars and students. academics make use of the digitized resources hosted by mdc and find them useful to build their scholarship, as evidenced by the citations made in their scholarly outputs. however, its impact goes beyond academic publications such as journal articles, proceedings, and monographs, including a significant number of dissertations and theses citing mdc resources. professional scholars accessing mdc collections online may save time and money compared to the travel costs required to consult the resources in situ. however, in the case of students, it is possible that in many cases they would be unable to access the collections had th ey not been digitized. when considering this type of impact, it should be borne in mind that the actual number of academic essays, dissertations, and theses citing mdc is presumably higher than the number recorded in this study. while all phd theses in catalonia are posted online, only bachelor and master dissertations with high grades are archived online in institutional repositories and, therefore, could be retrieved in our study. as expected, given the characteristics of the digitized collections, most citations come from academic documents in local languages in the fields of humanities and social sciences. most cited resources are located in a collection of digitized ancient catalan periodicals, although citations are spread among a wide range of collections. in addition to the use of mdc by scholars and students, there is also a significant proportion of professional publications written by librarians citing mdc. the results of the study show that google scholar is possibly the most suitable tool for conducting citation studies on the impact of digital heritage collections. given the characteristics of the resources contained in these collections, most citations are retrieved from local journals, which are frequently not indexed in large citation indexes such as web of science or scopus. even when they are indexed, our results show that scopus frequently fails to properly index citations to digital heritage collections, since most citations are not included in the final list of references but are inserted in the text, in footnotes, or in lists of resources employed. conversely, google scholar indexes the full-text of documents and, therefore, allows retrieval of these citations. these results are consistent with those found in previous research that showed that digital archive materials are more frequently mentioned in figures than in citations and described how citation information for digitized collections is hard to capture due to the lack of specific guidelines for citing digitized collection materials, resulting in inconsistent citation practices.10 in addition, as mentioned previously, a significant proportion of citations to digital heritage collections originates from documents indexed by google scholar, but not by scopus, especially theses and dissertations, but also reports, educational resources, etc. information technology and libraries june 2020 measuring the impact of digital heritage collections using google scholar | borrego 10 although our study provides evidence of the scholarly impact of mdc, it also suffers from some limitations. our results do not reflect any other kind of impact, such as on learning, teaching , or leisure. similarly, our study did not consider how mdc contributes to the long-term preservation of heritage collections. further research could explore these issues using participatory research methods, including surveys and interviews with users. endnotes 1 “eu member states sign up to cooperate on digitising cultural heritage,” european commission, last updated april 24, 2020,

rebecca c. knight: wichita state university, wichita, kansas; margaret f. lospinuso: university of north carolina at chapel hill; and john ulmschneider: national library of medicine. thesaurus-based automatic indexing and automatic authority control share common ground as word-matching processes. to demonstrate the resemblance, an experimental system utilizing automatic indexing as its core process was implemented to perform authority control on a collection of bibliographic records. details of the system are given and results discussed. the benefits of exploiting the resemblance between the two systems are examined. introduction it is not often realized how close the relationship is between automatic indexing using a thesaurus , on the one hand , and automatic authority control, on the other. making the connection is worthwhile for many reasons. the first has to do with terminology. though one would be naive to hope for a reduction in specialized vocabulary, it is helpful to appreciate that what is called a thesaurus in one application is referred to as an authority file in the other; that the two have virtually the same structure, similar working parts, and play the same role in controlling the content of fields in a bibliographic file in their creation and, at least potentially, during retrievals by users. a second reason emerges in system development. below we discuss the various ways that a library can implement authority control. they range from a fully manual system, where the authority file exists only in card form, to online, automatic authority management. there are intermediate points as well. for each of the automated implementations, the system investment in software can be great. recognition of the close parallel in function of these two library needs allows for parallel development of software for any of these stages. a third reason looks to the future. successful system-patron interaction manuscript received apri11981 ; accepted september 1981. automatic indexing/dillon, et al. 269 ought not to depend upon a patron's knowledge of the authorized entry forms currently in use for a library. first, the concept of a controlled vocabulary is far too narrow: authority control should encompass all fields available for searching. but the patron need not be aware of complicating details: substitutions of recognized variants for authorized forms ought to be carried out automatically during patron retrievals (with due regard, of course, for the intent of the patron). this article describes a project in authority control in a specialized system environment, one that is increasingly typical in many of its features. the file of records is relatively small, currently below 10,000, and has a potential for growth not exceeding 100,000. the collection, derived from the annabel morris buchanan collection of american religious tune books at the university of north carolina (chapel hill) music library, has many similarities with standard book collections, but its details vary greatly and cataloging conventions have been developed locally. its use for scholarly research is similar to that for any standard collection of bibliographic records. a great many such nonstandard collections exist-the morgue file in a newspaper, machine-readable data files, even properties marketed by cooperatives of real estate agencies. developing automated retrieval systems for such collections are similar enterprises, sharing similar goals and problems. in particular, all require extensive authority control similar to that required by a tune-book collection. the important feature of the method of authority control described here, one that makes it likely to be of interest to others, is its use of the same structures and software that are used for general vocabulary control. the three major software components we will refer to below are: thesaurus maintenance, automatic indexing, and automatic updating. these components antedated our effort to implement a similar system for authority control. when the problems that dealt with authority control per se were investigated, it was discovered that the system already available for subject control could be used exactly as it stood for authority control as well. initial experiments confirmed this relationship. 1 authority control and automatic indexing automatic authority control has been approached largely as a unique problem requiring special software development for its implementation. but authority control shares common ground with automatic subject indexing. both are term-matching activities based on a list of preferred terms plus a much larger list of match terms. each preferred term is tied to a number of match terms, but each match term is tied to only one preferred term. in the indexing environment, document text is examined for certain terms; these "free text" (uncontrolled vocabulary) terms are tied to equivalent (controlled vocabulary) terms in a thesaurus. when an uncontrolled vocabulary term is encountered in a document, its associated controlled 270 journal of library automation vol. 14/4 december 1981 vocabulary term is posted to the document as a descriptor. in authority control, document text is also examined for certain terms, e.g., author names. these "free-text" author names (i.e., names just as they appear on a title page) are tied to their authoritative name form (controlled vocabulary) in an authority file . when a "free-text" author name is encountered, the authoritative name is posted to the document or book (i.e., assigned as a heading or entry point). an automatic authority control system, then, is realizable by applying standard automatic subject-indexing software, which exploits the resemblance between the two processes. the input would consist of a thesaurus (in this case, an authority file) and bibliographic records; the indexing discovers matches between the list of possible terms in the thesaurus (variants of author names) with the "free-text" terms (title-page author names) , and posts the appropriate controlled thesaurus terms (authoritative author name form) whenever a match occurs. (see figure 1.) the tune-book project an experimental version of an authority control system using automatic indexing was implemented to test the feasibility of automatic indexing as i thesaurus i (authority file) \ \ i i \ fig. 1. at1thority control by indexing. matching and posting , l ' pdated records i \ ' i bibliographic records ~ automatic indexing/dillon, et al. 271 the core process for authority control. the goal was automatic authority control for the buchanan collection index, the first step in work on a more comprehensive project, an index of american religious tune books, in particular, the shape-note tune books. for the study of american cultural and musical history it is important to be able to trace the dissemination of these hymn tunes and texts, but the absence of a comprehensive index of american hymn tune books severely constrains such studies. many factors have discouraged scholars from constructing an index, among them the magnitude of the repertory . using computers to sort, file, and print reduces many of the problems associated with the size of the repertory, but does not address those created by the diverse forms of names and texts used by the tune-book compilers. correct hymn titles and especially accurate composer attributions were not important to the compilers of the tune books. consequently, although many tune-book compilers did attempt to indicate who had composed the work, the names of the composers appeared in various forms. for example, the name "israel holdroyd" might appear as simply "holdrad" or "holdrayd" with no first name given, or a first initial might be added, or an abbreviated first name, such as "is." might be used with one of several forms of the family name. automatic authority control over these names is necessary to the study of this collection, since only automatic means can address the problems of magnitude encountered in approaching the index as a whole. the database now contains about 6,000 records for these tune books. they are stored in marc format with variable-length fields giving a variety of information about each tune . creation of the authority file a thesaurus of authority records for the buchanan collection was manually created and placed in an online file. the initial authority file comprises a selection of composers whose names are present in conflicting forms in the present database. these were obtained by analyzing the file sorted by tune names, noting those tunes for which it appeared that the name of the same composer was given in more than one form. all forms of the name found were entered on cards along with the name of the tune (or tunes) through which the relationship was established . we used an explicit algorithm as a guide in determining which names were actually forms of the same name (see appendix for details). this process resulted in a list of 266 distinct composers, each with one to four different name forms. all were compared with the list sorted by composers, noting additional forms. these names were then checked in several reference works, and authoritative forms (with dates) were established when possible. implementation software systems file processing for the tune records and the authority thesaurus was 272 journal of library automation vol. 14/4 december 1981 accomplished using a local software product, bibliographic/marc processing system (bps). bps is a general-purpose software package for the manipulation of marc-format records. this experiment used bps subsystems for creation of marc-format records, sorting and formatting, and file updating (i.e., updating a master file with the contents of a transaction file). the automatic indexing program used here was intended as part of a thesaurus-based document query system. 2 it is compatible with bps, but utilizes generalized automatic indexing principles-its compatibility depends only on properly formatted thesaurus and bibliographic records. it includes file-processing programs for the thesaurus (authority file) and the bibliographic records (tune records) and a matching program that performs the indexing. posting of the authoritative name forms to the proper marc record is done with standard bps updating procedures using output from the matching program. automatic authority control process as input the system uses a thesaurus and the text of fields selected from marc-format document records. the thesaurus consists of pairs of terms: the first of each pair is the term searched for in a document, the second is the authority term assigned to the document, whenever the first term is found. figure 2 gives examples. the text may be abstracts, titles, or the contents of any field selected from the documents for authority control. in this case, the text is derived from the composer field; for authority work in general, any field requiring authority control would be input. the first step in authority control is as follows. the text sample and a stop-word list are input to the initial text-processing program. the incomau'ihcrity fcri'i cole, j_ i cvle, joh~ 1774-1855 clarkf", thos. 1 clark, thomas \:ol e!' , ~ eo. i cuzens, 9. / cuzens, benjamin ilall , ::;_ bi ba 11 , r. fholraj / hcld r oyd , israel aolroyd i hcldroyd, israel fig. 2. thesaurus/authority file format . automatic indexing/dillon , et al. 273 ing text (in this case, composer names) is separated into individual words. the stop-word list is used to remove designated words from the input, which in authority control might be titles of address and so onterms such as "miss," "elder," or "reverend." (automatic indexing uses the stop-word list to eliminate similarly noncontributory terms, such as conjunctions and prepositions.) the processing program can also convert plurals to singulars if desired. the purpose of this option in automatic indexing is to pare down variants in order to increase matches by standardizing term forms. however, plurals are not converted in authority control, since names are usually distinguished from one another by their full forms. the processing produces a list of individual terms. each term is given once along with the number of words in the term, then broken up with the document number attached to each piece. the thesaurus authority records are edited by the thesaurus processing program into specially formatted matched pairs of variant and authoritative forms. input is the match-term/variant-term file (figure 2) and the same stop-word list used for document processing. the stop-word list eliminates all unwanted words in the list of variant name forms. output is a file containing all possible name forms (variants), the number of terms in each name and their positions in the name, and the authoritative name form, as in figure 3. next the two files are used as input to a matching program that creates an inverted file of the processed document text, then compares each match term from the prepared thesaurus with the inverted file. a match is discovered according to one of the following criteria: 1. exact match: match term and document term are the same words, in the same order, and adjacent. 2. stop word exact match: words are the same in match term and in document term, and in order, but deleted stop words may intervene between words in the document term. 3. any order match: term must be the same words and adjacent (i.e., without intervening words) and may be in any order. va!'iani twc!ld s ~:utiv~ auti:-ci\ily ?cs: no fch hlstin'js, 'ihos. 2 1 2 rastinq~ , tl:hii.l s 17~4-l tl7 _ hastl.nqs, l h:>s :le i 1 2 rds tl nq.< , th.:>llll s 17cl~ 1 -!72 holde a':! l!ol:lccyd , l s cd<! l holdcoy1 i· holiroyd , i sra~: housec, w 2 1 2 lid u se [', willia m 1 '3 12 -1tho fig. 3. processed authority file. 274 journal of library automation vol. 14/4 december 1981 4. stop word any order match: terms must have the same words and in any order, but intervening stop words are ignored. 5. any match: any word of the match term may be in any part of the document text in any order. these match criteria are similar in intent to the criteria for deciding composer-variant forms/composer-authority form match mentioned above and presented in the appendix. an interesting possibility is to use such match criteria to discover variant author name forms in creating the authority file, since many variant forms result only from misspellings, title attributions, and so on. pseudonyms would not be detected, but such a procedure would be useful in collating forms morphologically similar. the experiment used criterion two, one of the most restrictive; the "freetext" composer name must match exactly and with its parts in the same order (except that stop words, such as "miss" or "elder," may intervene) as the variant author name before an authoritative form is posted. this seems the most reasonable choice for this project; presumably more flexibility could be achieved by adding criteria to the match process or by allowing boolean combinations of criteria analogous to those outlined in the appendix. the final output from the match module is three files: a print file of all match terms, a file of all unmatched authority names, and a file constructed for the update of the bibliographic records, giving the document and field to be updated and the update term. the print file is a record printed for each term matched. the record gives the variant form matched, its field type, the proper authoritative name form as given in the thesaurus , and the identifier numbers of the documents in which the term is found. field type is an identifying code assigned to each term in the prepared thesaurus, not necessarily the same as those identifiers in the marc-format authority file; here, the field type is preferred composer n arne (pcn). an example of the printed output file is in figure 4. the update file is for use in an update program that posts the authoritative name form assigned by the indexing. it contains the document identifier number in which a match was found, the field type of term found (pcn), and the authoritative name form. the update program uses this file to add the authoritative composer name form as a new bibliographic data field to the appropriate bibliographic record, assigning as a field identifier the field type identifier accompanying it. figure 5 gives the new records with added fields. during the update process, a file containing all records not receiving a new authority-name field is generated. these records may contain a new variant of an authoritative name already in the file or a name altogether new to the file;

medical librarian at the city university of new york (cuny) school of medicine. © 2023. abstract in 2021, the assessment-data management librarian at lehman college library decided to conduct a privacy audit of the library’s public computers and networks. this audit comprised one of the library’s two annual formal assessments of resources and services. the american library association’s (ala) library privacy checklist for public access computers and networks was selected to review 17 key items related to protecting user privacy and confidentiality. faculty and staff from circulation, library technology, and online learning identified 10 indicators needing work. suggestions are provided for collaboratively resolving these issues and future steps are described to continuously maximize the online security of the campus community. introduction lehman college library has a longstanding deep commitment to safeguarding the personal information of the college’s students, faculty, and staff. the library maintains an extensive collection of research guides offering resources for its librarians on all aspects related to patron privacy and confidentiality. library units frequently collaborate to ensure optimal adherence to professional best practices. in 2021, the assessment-data management librarian resolved to conduct a privacy audit of the library’s public access computers and networks during the 2021–2022 academic year. the audit served as one of the library’s two annual assessment projects. as one of the college’s administrative, educational, and student support (aes) units, the library selects and evaluates two resources or services every year, concluding with a detailed report. the reports are submitted to the office of assessment and are included within an extensive institutional effectiveness assessment report. privacy audits are “procedures to ensure that your organization’s goals and promises of privacy and confidentiality are supported by its practices. as a result, they protect confidential information from abuse and the organization from liability and public relations problems.”1 they are an important assessment procedure that should be undertaken periodically to help minimize the collection, retention, and dissemination of data—sometimes sensitive in nature—associated with library users. the american library association (ala) further explains the significance of upholding these values: “in their provision of services to library users, librarians have an ethical obligation, expressed in the code of ethics of the american library association and the library bill of rights, to preserve users’ right to privacy and to prevent any unauthorized use of user data.” 2 despite this importance, there are challenges facing librarians that confound procedures and protocols to optimize privacy protection. these include complex technologies and laws, lack of employee time to dedicate to these tasks, and a lack of advocacy or complaints from users.3 information technology and libraries september 2023 privacy audit of public access computers and networks at a public college library 2 angell public access networks and computers were selected for this audit due to their essentiality in safeguarding the information-seeking needs and practices of the lehman college community while on campus. this was a particularly timely project due to the fact that students were returning to campus in droves following covid-19 related closures and had a strong need for public computer access. critical aspects of computer privacy identified by ala are access to privacy policies, erasure of browser activity and personal data, protection from malware, and prevention of monitoring and tracking. literature review privacy audits can be conducted on a wide range of resources and services within libraries. these areas include electronic resources vendors, integrated library systems, public networks and computers, assistive technology, and library websites. magi urged fellow librarians to conduct privacy and confidentiality audits to guard the public trust as far back as 2006, specifying 12 potential areas.4 these include records of websites visited and emails sent and received on library computers. ala offers extensive checklists dedicated to assisting libraries and vendors in conforming to the library privacy guidelines. these documents are products of ala’s intellectual freedom committee. privacy audits are undertaken by academic libraries,5 law libraries,6 school libraries,7 and public libraries.8 despite toolkits on conducting privacy audits from ala and organizations like the library freedom project, there is a major lack of scholarship on these compliance procedures within library and information science literature.9 public libraries provide the most freely available documentation, although most of this information is presented on a library website and not written up as scholarly articles. a prime example is san jose public library, which offers a detailed account of a privacy audit across departments, including access services, technical services, marketing and communications, and security.10 choosing not to conduct privacy audits can jeopardize the anonymity and security of library users. this concern is increasing in an era heavily impacted by the proliferation of big data and its ability to impose unprecedented surveillance. marden warns of library users’ information nonconsensually being bundled up and applied to “trend analyses, grant funding, and reporting to local governments.”11 library users may not even be aware of these risks when sitting down at a computer to research, browse, or write, making it even more important for these security risks to be mitigated. in the days following the passage of the usa patriot act, which gave law enforcement agencies new powers to monitor patrons and obtain circulation records, coyle suggested every library designate a “privacy officer.”12 this designee would stay abreast of privacy issues impacting the library and would oversee leading privacy audits and maintaining privacy policies. a privacy audit is also useful because it plays an instrumental role in a library developing or revising a privacy policy.13 it can reveal strengths and weaknesses in library policies and procedures and provide an opportunity for the staff to collectively devise more robust and current privacy protections. currently, many academic and public libraries openly display patron data privacy policies on their websites. a particularly thorough and well-enumerated policy is that of mit libraries. within the policy is the statement that the document is periodically reviewed by the libraries and campus audit division.14 a privacy policy is just one way that librarians can help teach users how to take steps to best protect their data, especially on computers in public settings and/or with unsecured wireless information technology and libraries september 2023 privacy audit of public access computers and networks at a public college library 3 angell connections. key tenets of privacy literacy can be incorporated into critical thinking skill-building foregrounded in existing information literacy instruction sessions.15 these skills can include online image management, achieved in part by carefully evaluating information prior to posting on social media sites. currently, there is very little scholarship exploring the application of the ala privacy guidelines and checklists within library and information science literature. the author hopes that this article can play a role in helping to increase the proliferation of privacy audits at academic libraries and , therefore, avoid online threats including identity theft, tracking/spying, and phishing. methods this study was conducted at lehman college, a medium-sized urban college (about 15,000 students) in the bronx, new york. lehman is one of the 25 colleges within the city university of new york (cuny) system. the library does not have its own designated patron privacy policy; we default to a systemwide privacy policy.16 ala’s library privacy checklist for public access computers and networks was used as the evaluation tool in this audit.17 the checklist was employed in conjunction with ala’s library privacy guidelines for public access computers and networks to determine the level of personally identifiable information and data recorded by the library’s computers and devices. 18 these particular assessment resources were selected due to their development by the united states’ premier library professional organization. the instruments are still relatively new, approved by ala in 2017. to allow for streamlined evaluation of the 17 checklist items by multiple library employees, the assessment-data management librarian followed the lead of san jose public library and transferred the information from the ala website to a shared google document. columns were added next to each checklist item for status (needs work, accomplished, n/a), department (it, access, technical services), and a notes section for key comments related to past, present, and future planning and/or implementation. the checklist was sent to the library technology coordinator, the web services-online learning librarian, and the head of access services. they independently reviewed the checklist and evaluated the privacy items falling within their professional duties. the tool was also shared with the business librarian, a library privacy specialist, for her expert review. an image of the completed checklist is presented in figure 1. results analysis of the 17 items by library employees reveals that while the library is in full compliance with some of the guidelines devised by ala, there remain steps to be taken that can enhance privacy and confidentiality of patron information transactions on our computers and network. these six fully accomplished items (identified in fig. 1) will not be further discussed in this report, as the library has already achieved these goals. one other item will not be evaluated (“configure any content filters to not collect or share browsing data”), as it has been determined to not be relevant to the library’s purposes. ten items flagged as needing work will be focused on for the remainder of the report, accompanied by evaluator notes and potential future steps. information technology and libraries september 2023 privacy audit of public access

computers and networks at a public college library 5 angell discussion after careful study of numerous library privacy websites and reviews of existing literature on privacy within library science literature, combined with the useful appraisal of the three evaluators, the assessment-data management librarian devised recommendations for the increased safeguarding of privacy and confidentiality for library patrons. these recommendations are provided in tandem with the recognition that library staff already provide the campus community with ample privacy protections. it is important to acknowledge that ala’s guidelines function within the understanding that not every library can accomplish every item or priority on the checklist due to factors related to technical expertise, resources/funding, and organizational structure. the 10 priorities noted by the evaluators as needing work are listed in table 2, accompanied by a perceived barrier (when relevant) and recommendation for a potential solution. the generation of the barriers and recommendations was and will remain a collective effort across library units. additional recommendations for the priorities were solicited for this project from library and information sciences scholarship. table 2. recommendations for accomplishing outstanding tasks related to privacy within public computers and networks. item needing

information for last year was purged when the circulation unit made changes to visit criteria 1 hour/2 hour/day pass. the ability to accomplish the aforementioned tasks is contingent on continued close collaboration between library employees. while conducting the audit and writing this report is an important step in maintaining data privacy, it remains a work in progress. the assessment-data management librarian recommends formation of a task force to focus on achieving as many of these tasks deemed realistic given existing financial and personnel circumstances. duke libraries describe development of a data privacy task force.19 its main duties are to “review the audit report and gather any additional data necessary to inform their work, which may include setting priorities, working with departments and units to create policies where they are lacking, making recommendations for how to communicate policies to patrons, and other tasks determined by the task force.” the library’s task force could meet on a semester basis to reflect on information technology and libraries september 2023 privacy audit of public access computers and networks at a public college library 7 angell the status of data privacy protections and reassess if interventions are functioning efficiently or require modification. further research reveals additional steps taken by external libraries to enhance online privacy protocols. robinson began using the free certificate program let’s encrypt for library servers and services at the university of alaska.20 he provides instructions for employing the program to an api server. in addition, an extensive privacy audit at san jose public library resulted in a detailed action plan.21 relevant items included developing a library data breach policy and installing research tracking plugins like privacy badger on public computers to prevent collection of user data by unwanted third parties. ala’s library privacy policies report details an analysis of over 100 american academic and public library privacy policies.22 this document offers extensive information on how a wide selection of libraries attempt to best protect patron privacy regarding data collection, third-party platforms, data security, and data retention. the report lists specific examples of text culled directly from library privacy policies, some of which pertain directly to material on ala checklists and can be used to better safeguard privacy and confidentiality at this library. for example, rutgers university libraries assures users that they “remove cookies, web history, cached files, or other computer and internet use records and other software code that is placed on our public computers or networks after each use.” this author maintains that all policies should include a recommendation to use duckduckgo for web browsing, as well as the posting of signs with this recommendation in public computer areas. in general, duckduckgo is as efficient in resolving information queries as google and does not store or track search history.23 the lack of targeted ads on duckduck go, for example, shows the level of privacy that can be maintained while using the browser. lastly, the assessment-data management librarian suggests sharing this report with the university library system’s privacy roundtable. the roundtable could review these findings and contribute recommendations from experiences at their own libraries, thus potentially improving data security and confidentiality for both the college community and other campuses within the university system. this is particularly important as students, faculty, and staff in the system are free to use libraries at any of the campuses (except for the law school). conclusion there are a few limits of this privacy audit worth mentioning. first, the assessment was conducted during the covid-19 pandemic within a hybrid remote/in-person working and learning environment. employees and patrons alike were on campus part time, leading to far less computer and network usage than in previous years. a related limitation is that evaluation with the ala checklist was conducted by each library participant separately over email, not as a group working in tandem in real time. a future study could benefit from the audit occurring in person, with each individual able to observe and assess existing conditions together in relevant library spaces. another limit is that this project was spearheaded by the assessment-data management librarian, who does not possess a professional background in information technology and library systems. while this librarian had ample support and assistance from colleagues during the audit and writing of this report, her own direct knowledge of public computing and networks can be information technology and libraries september 2023 privacy audit of public access computers and networks at a public college library 8 angell considered a weakness. this limit reiterates the necessity of interdepartmental collaboration on running privacy audits and successfully applying fixes identified during the process. to capably implement the priorities determined as needing work, it would be optimal to create a combined library data privacy task force. the most critical aspect of an audit, as argued by matz, is that it is “only an initial assessment, because a privacy audit should be an ongoing process for the library and its staff.”24 encroachment on online privacy by not just scammers or other malicious parties, but companies we often know and trust, does not require a one-time fix. the latter has been reported to include facebook, zoom, whatsapp, and google.25 an analysis of public computers and networks is only one of many types of privacy audits that libraries can conduct. ala has done an excellent service for the library profession by devising and sharing their library privacy checklists. future studies within academic library scholarship can explore audits of different key aspects of information security, such as assistive technology, vendors, and integrated library systems. by conducting these studies and sharing our findings with the greater community, we as a profession can collectively greater protect user data. acknowledgements i would like to thank the following lehman college colleagues for their

classical musicians to cancel in-person recitals and concerts and led to the exploration of virtual alternatives for engaging audiences. the apparent solution was to livestream and upload performances to social media websites for audiences to view, leading to income and a sustained social media presence; however, automated copyright enforcement systems add new layers of complexity because of an inability to differentiate between copyrighted content and original renditions of works from the public domain. this article summarizes the conflict automated copyright enforcement systems pose to classical musicians and suggests how libraries may employ mitigation tactics to reduce the negative impacts when uploaders are accused of copyright infringement. introduction the covid-19 pandemic, unlike anything the country has seen in a century, forced industries to reevaluate the manner in which they provide services to the public. businesses and citizens everywhere made hairpin turns as they quickly searched for virtual alternatives to everyday inperson activities. with many remaining home for extended periods of time, demand for digital content and entertainment skyrocketed. in may 2020, comcast reported a 40% increase in online video streaming since march 1, just weeks before governments instated stay-at-home mandates.1 throughout the year, subscription-based streaming services saw enormous surges in customer usage and, likewise, social media platforms saw a significant spike in content production and consumption.2 daily blogging on facebook replaced in-person interactions, and youtubers generated higher volumes of videos to meet viewer demand. classical musicians were also heavily reliant on social media platforms in order to showcase performances as pointed out in the washington post article “copyright bots and classical musicians are fighting online. the bots are winning.” highlighted by american library association’s american libraries, the article illustrated the toll social media content moderation algorithms took on classical musicians sharing their performances online.3 this article became the starting point for the 2021 study “are youtube and facebook canceling classical musicians?,” which investigated the relationship between classical musicians and automated copyright enforcement systems.4 the following is a summary of this study’s findings and brings attention to the role libraries can play in aiding classical musicians facing copyright infringement claims. automated copyright enforcement evidence shows that automated copyright enforcement systems wrongfully remove useruploaded materials in the name of copyright protections on a regular basis.5 in fact, it happens so often that the australian broadcasting corporation began wittingly dubbing such instances “copywrongs.”6 these algorithms are not designed to distinguish between recordings of music mailto:berkowitza@hcflgov.net information technology and libraries june 2022 classical musicians v. copyright bots | berkowitz 2 owned by record labels and those shared online by freelance musicians. they are instructed to recognize copyrighted recordings and content resembling those recordings as identical matches, ensuring the protection of intellectual property from unauthorized reproduction. as such, automated content moderation systems are incapable of making allowances for the performance of works from the public domain. such performances comprise nearly all of a classical musician’s repertoire. automated copyright enforcement systems are typically based on a combination of matching and classification methods. the most effective matching technique for content moderation is perceptual hashing, which isolates unique strings of data (hashes) taken from an uploaded file and compares distinguishing markers and patterns to a database of samples provided by copyright owners.7 this technique allows systems to detect exact matches and iterations of the original work, such as live recordings and remixes.8 among classification methods, artificial neural networks with deep learning are best suited to the task of algorithmic moderation. consisting of a network of nodes, they are meant to simulate the structure and function of neural networks in animals and humans.9 this enables them to solve multifaceted, dynamic problems, which makes them ideal for instantaneous content moderation, allowing them to identify musical similarities in real time.10 both youtube and facebook enable users to upload recordings and broadcast live feeds to their websites. matching techniques are used to review prerecorded content since the upload process allows for automated systems to sample the material for comparison to the companies’ hash databases before allowing the recording to be posted.11 in contrast, live broadcasts are transmitted instantaneously and allow for no time to review the footage before it is visible online. therefore, hashes cannot be sampled from streaming content, requiring that classification methods using training data identify infringing material on the fly.12 while these algorithms make content moderation easier, they are limited in their capacity. one study showed that youtube is surprisingly inaccurate in its attempts to recognize infringing material in live broadcasts, failing to identify 26% of copyrighted footage within the first thirty minutes of streaming and blocking 22% of non-infringing livestreams.13 research strongly suggests that the only factors considered by music copyright enforcement systems are pitch, volume, and melodic and harmonic contour.14 those values alone cannot be used to distinguish copyrighted works from the public domain. as such, these systems are not yet advanced enough to account for the total complexity of human creativity, and human intervention is required before these programs systematically accuse uploaders of copyright infringement.15 compositions in the public domain are not subject to copyright; however, recorded performances of compositions from the public domain can be copyrighted. individuals may upload or livestream their own performances of classical music without fear of infringing copyright but may not upload another musician’s copyrighted recordings of the same pieces. for example, no one owns the copyright to bach’s cello suites and, therefore, anyone can profit from performing these works. sony music, though, owns the copyright to yo-yo ma’s recordings of bach’s cello suites, and anyone uploading these specific recordings to social media would be infringing copyright and subject to the repercussions. unfortunately, automated copyright enforcement systems often misidentify an individual’s performances as copyrighted recordings. information technology and libraries june 2022 classical musicians v. copyright bots | berkowitz 3 the impact on classical musicians classical musicians are accustomed to having their content misidentified for infringing copyright, but with the pandemic forcing many more musicians to share performances regularly on social media, the problem has become ever more pervasive. adrian spence, the artistic director for chamber ensemble camerata pacifica, found himself appealing multiple copyright claims from both facebook and youtube. on occasion, he would dispute several claims issued by different copyright owners for the same recording. until these issues were resolved, facebook suspended camerata pacifica’s ability to livestream, and youtube displayed a notification on their channel informing viewers that their videos were likely to be removed due to anticipated copyright infringement.16 owen espinosa, a high school senior, was preparing for a piano recital, and during rehearsal, facebook ended his livestream over claims of copyright infringement. he was unable to successfully appeal the claim which meant that facebook would not host his performance. instead, he had to broadcast his recital on an acquaintance’s youtube channel.17 michael sheppard, a professional pianist, has had broadcasts interrupted and videos removed by facebook multiple times with notifications stating that music owned by naxos of america was detected in his performances.18 after facebook rejected his disputes, sheppard took to twitter, alerting naxos of his situation. his videos were eventually restored, but nothing could be done about his livestreams.19 the violinist.com broadcasts weekly, hour-long concerts featuring multiple guest musicians. during one of these performances, facebook muted child violinist yugo maeda due to a claim of copyright infringement. after appealing the notice, facebook unmuted maeda’s performance three days later.20 while covid-19 exacerbated the issue, classical musicians often had their performances interrupted or removed from social media. in 2019, conducting students at the university of british colombia had their facebook live feed interrupted over copyright infringement claims and, in 2018, facebook removed a recording of an in-home performance given by pianist james rhodes also stating that the music infringed copyright.21 also in 2018, the australia broadcasting corporation’s abc classic fm livestreamed a performance of beethoven’s symphony no. 9. the broadcast ended with facebook issuing a claim stating that the music in question was owned by two different copyright owners.22 in 2016, violinist claudia schaer disputed several of youtube’s copyright claims. she typically had success with these appeals, but one of her recordings received three claims from different copyright owners. she was able to refute two of them; however, the third remained, and she was warned that if she was unsuccessful in her second attempt at appealing the claim, her account would receive a copyright strike, deleting her video from the site permanently. she felt both intimidated and aggravated by the ordeal.23 the author of this article has also had to refute a copyright infringement claim on youtube. according to the notice, 51 seconds of the author’s approximately five-minute performance of beethoven’s “für elise” infringed copyright. as a result, the claimant authorized youtube to include ads in the video, allowing them to generate revenue. the dispute was upheld after the claimant’s 30-day window for a response expired. although the author does not rely on monetized videos and livestreams for income, it is unethical for another entity to profit from the work of an unaffiliated individual. information technology and libraries june 2022 classical musicians v. copyright bots | berkowitz 4 disputing a copyright claim while there is recourse for uploaders facing copyright claims from social media sites, the appeals process can be lengthy and overwhelming. it can take more than two months for youtube to render a verdict when a musician disputes a copyright notice. during this span of time, classical musicians depending on ad revenue cease to generate income as these funds are held by the company until a final decision is made, at which point all profits accumulated by the video are released to the appropriate party. if the claim is upheld, the recording may remain online with proceeds going to the supposed copyright owner.24 uploaders may attempt to refute the result, but a failed appeal leads to the video’s removal and a copyright strike levied against the uploader s preventing them from livestreaming and monetizing videos for three months. should this occur, a counter notification can be issued which insists that the content in question has been mischaracterized as infringing and requires that would-be copyright owners file a lawsuit to uphold the claim. after three strikes, accounts are permanently deleted along with all associated uploads.25 the time that elapses for a final verdict along with the suspension of uploading and livestreaming permissions due to a copyright strike amounts to more than five months without being able to sustain an income. when a single performance is charged with multiple claims from different entities, as in the aforementioned examples, the uploader must dispute each one individually. this makes it easy to accumulate copyright strikes, risking account termination. it would be reasonable to assume that many classical musicians who endure these circumstances avoid the dispute process for fear of youtube removing their recordings, enforcing limitations on their ability to broadcast and monetize videos, and even permanently deleting their accounts. meanwhile, mistakenly recognized copyright owners can leverage this by appropriating the earnings generated by the work of unaffiliated musicians. furthermore, should the matter be redirected to the courts, the uploader faces the burden of retaining legal counsel. youtube algorithms deal with approximately 98% of all copyright issues and, because youtube’s business model generates profits primarily via user-uploaded content, it has been found to show bias towards established copyright owners.26 copyright owners can set preferences for how they want the system to react to instances of copyright infringement, resulting in the automatic monetization of 95% of claims for the copyright owner. as a result, user uploads make up 50% of the revenue generated by youtube for the music industry.27 although google reported in 2018 that 60% of disputed claims were found in favor of accused uploaders, the system clearly benefits established copyright owners.28 all of the aforementioned musicians who were accused of copyright infringement had their livestreams interrupted, saw their videos removed, and witnessed companies profiting from their work performing music that has long since passed into the public domain. youtube’s video series copyright and content id on youtube attempts to educate users on how automated copyright enforcement and the dispute process work, and while fair use and copyright permissions are discussed, the public domain is never mentioned; although, youtube does offer a brief explanation of the public domain on its help site.29 according to the us copyright act, the duration of copyright extends to 70 years after the death of the known composer, and for uncredited compositions or those composed by a musician under a pseudonym, copyright is recognized for 95 years from the date the work was published or 120 years from when it was composed, depending on which information technology and libraries june 2022 classical musicians v. copyright bots | berkowitz 5 expires first.30 while record labels are fully within their right to protect the recordings they own, that should have no bearing on individual musicians performing pre-twentieth-century music. the majority of online music consumption occurs on social media sites with 47% of the market share going to youtube.31 reports from deezer showed a near 20% increase in users listening to classical music since the start of the pandemic.32 given that more users are gravitating towards listening to classical music, and that the most popular digital access point for music is youtube, classical musicians coping with pandemic-induced restrictions were presented with what should have proven to be a lucrative opportunity. adhering to social distancing requirements and stay-athome mandates meant musicians cancelled their performances, leading to an exploration of virtual alternatives such as uploading recordings and livestreaming. obstructing these activities interrupts their sole source of income. conclusion while researchers have suggested a handful of improvements for automated copyright enforcement systems, they have not addressed the role that libraries can play in assis ting classical musicians.33 the tampa-hillsborough county public library, prior to the spread of covid-19, maintained four branches outfitted with recording studios; today, that number has grown to five. prior to pandemic library closures, recording studios were reserved just over 800 times, amounting to about 1,600 hours of usage between january 1, 2019 and march 13, 2020. patrons using the recording studios produce music and videos with the intention of uploading them to social media. other libraries with recording studios likely see their patrons doing the same, but without knowledge of copyright. libraries have the means and the motive to assist classical musicians. libraries can hold classes covering the basics of copyright, fair use, and the public domain, or that expand upon how automated copyright enforcement systems work on social media. library staff, however, may feel overwhelmed by the numerous texts on these subjects and may not know where to begin. an excellent starting point is the frequently asked questions page on the us copyright office website. this webpage offers explanations for a broad array of copyright-related issues and questions.34 fair use allows for unauthorized borrowing from a creative work; however, navigating how fair use is determined is always challenging. steven m. davis’ “computerized takedowns: a balanced approach to protect fair uses and the rights of copyright owners” is a reliable point of reference for defining fair use, its application in copyright infringement cases, and ethical and legal implications regarding the limitations of algorithmic moderation systems.35 for a thorough look into the mechanics and applications of automated copyright enforcement, refer to the previously mentioned “are youtube and facebook cancelling classical musicians?” this article offers a synopsis on the shift from physical to digital media, descriptions of different algorithmic models developed specifically for copyright enforcement, and an account of how youtube’s and facebook’s copyright enforcement systems came to be.36 libraries can also offer help sessions that support patrons through the copyright claims dispute process. the youtube dispute interface is user friendly, and the instructions are comprehensible. throughout each step, explanations are offered to clarify what is being required of the user. for example, when asked for the reasoning behind the dispute, the user is offered four options: the disputed material is original content, the user has acquired permission to reproduce the co ntent, the content falls under fair use, or the content originates from the public domain. once selected, information technology and libraries june 2022 classical musicians v. copyright bots | berkowitz 6 additional explanations for each option are given in order to provide further clarification and context which allows the user to reconsider their choice and also helps the user better explain how their content falls under the selected category. finally, the user is asked to provide a narrative explaining how the content in question does not infringe copyright. facebook’s counternotification process is less generous, providing brief, ineffectual descriptions of copyright and a simple form requesting the user’s personal information and explanation for why the copyright infringement claim is unfounded. after library staff demonstrate the use of these interfaces, patrons can be guided to library resources to help them articulate and refine their arguments. for anything that cannot be found among the library’s collections, library staff may need to assist with internet searches, or patrons may request materials through interlibrary loan. additionally, patrons may still feel overwhelmed by the terminology being presented, which would further support the need for library programming that covers copyright-related topics. when considering the research involved to produce a convincing counterargument, information literacy and metaliteracy classes may be warranted. libraries can also encourage patrons to include descriptions in their uploads and livestreams with links to supporting evidence explaining that the featured music belongs to the public domain, and as the uploader, they own the rights to recordings and broadcasts of their own performances. the public domain description on youtube’s help page provides links to columbia university libraries’ copyright advisory service and cornell university’s copyright information center, and it suggests that these resources can lead to supporting evidence regarding works in the public domain.37 another excellent resource is the international music score library project’s petrucci music library. this database of almost 200,000 compositions belonging to the public domain features both sheet music and recordings of each of these works.38 users can also point to the public domain song anthology, a book comprising 348 popular songs from the public domain; the entire text can be downloaded from the publisher’s website.39 these resources and explanations can be included in disputes to support the reasoning for why a copyright claim is invalid. it should be noted that library employees are most often not lawyers, and as such, it is ill-advised to answer direct questions about the specific legality of the myriad of situations musicians face when disputing copyright claims. these matters require expert, specialist knowledge with which library staff are not equipped. the role of the library should only be to provide access to resources and inform the public on various issues regarding the use of information. as information specialists, librarians are in a unique position to educate patrons on information policy, and in this case, copyright. library systems with law libraries or with access to law collections and databases would be especially suited to teach patrons about copyright, guide them through the dispute process, and assist them with gathering resources to support their counterarguments. the tampahillsborough county public library and other systems like it that are outfitted with both music recording studios and a law library are encouraged to offer such services. hopefully, this overview of automated copyright enforcement, its impacts on classical musicians, and the suggestions to libraries offered here will promote further conversation that eventually leads to action and a possible solution. perhaps, as progress is made, automated copyright enforcement systems will grow more hospitable towards user-generated recordings and livestreams of classical music. after all, social media should be able to freely host the artistic talents of all musicians. information technology and libraries june 2022 classical musicians v. copyright bots | berkowitz 7 endnotes 1 “covid-19 network

academic libraries is a topic of interest for both library professionals and researchers, little is known about how they are used in library reference service, especially in academic libraries in canada. this article aims to fill this gap by conducting a web-based survey of 106 academic library websites in canada and analyzing the prevalence and characteristics of chatbot and live chat services offered by these libraries. the authors found that only two libraries were using chatbots for reference service. for live chat services, the authors found that 78 libraries provided this service. the article discusses possible reasons for the low adoption of chatbots in academic libraries, such as accessibility, privacy, cost, and professional identity issues. the article also provides a case study of the authors’ institution, the university of calgary, which integrated a chatbot service in 2021. the article concludes with suggestions for future research on chatbot use in libraries. introduction with the recent launch of artificial intelligence (ai) chatbots (e.g., chatgpt and bing-chat), and springshare’s introduction of a library-focused chatbot product, it seems probable that more libraries will adopt chatbot technology to provide reference services 24/7.2 this article attempts to document these changes by surveying academic libraries in canada to determine the current popularity of chatbot use in reference service. at this time, most of the chatbots used in the library market are essentially interactive faqs, where keywords entered by the user return suggestions to pages that may answer the query. however, with the recent emergence of advanced tools, domainspecific enhancements to chatbots leveraging artificial intelligence could cause an explosion of ai chatbot use in the library world. literature review this research focuses on the use of chatbots by academic libraries in canada. there are many different terms for chatbots (e.g., digital assistants, conversational agents, etc.), and these terms are used inconsistently in the media and across the literature. 3 a chatbot can be defined as a system that simulates a conversation with a human, in real time, using ai technology.4 chatbots respond to user interactions in sentences “that track the conversation in a meaningful way to humans.”5 although both involve user interactions in a digital space, chatbots are not to be confused with live chat services, which is when a user can converse with a library staff member in a synchronous online session. mailto:julia.guy@ucalgary.ca mailto:ppival@ucalgary.ca mailto:carla.lewis1@ucalgary.ca mailto:kim.groome@ucalgary.ca information technology and libraries december 2023 reference chatbots in canadian academic libraries 2 guy, pival, lewis, and groome notably, chatbots use natural language processing (nlp) to communicate with users. broadly speaking, nlp is the “use of computer technology to assist in or complete tasks involving the processing, categorizing, analyzing, or interpreting the meaning of human language.”6 in the context of chatbots, nlp has two main functions, natural language understanding (nlu) to interpret inputs and natural language generation (nlg) to produce a language response.7 “natural language” in this context refers generally to human language, spoken or written, although there is research and advocacy around the further inclusion of signed languages in nlp research and development, including a recent paper by yin et al.8 furthermore, nlp also eliminates the use of boolean operators, traditionally a requirement of library interfaces. an additional benefit of nlp technologies is that they are intuitively usable for many people, given that users communicate with these systems in the way that humans are used to communicating, through conversation. due to this minimal barrier to entry for many users, chatbots are increasingly being implemented as online assistants in many different contexts .9 the increasing popularity of nlp technology also means that when users encounter a chatbot in a digital environment, they are likely familiar with how to interact with it. chatbots are therefore a “costeffective and accessible supplement to manual customer service.”10 with ai technology on the rise, researchers are exploring the implications of integrating these technologies into academic libraries, and several literature reviews have been conducted on this topic over the last few years.11 noteworthy benefits of chatbots include the potential to free up staff time and the ability for these systems to assist students remotely, 24/7.12 despite the growing interest in using ai in academic librarianship, as tait and pierson observed, much of the existing literature on library applications of ai is predictive and speculates on what the use of ai might look like for libraries in the future.13 for example, research has explored stakeholder’s perception of risks associated with library adoption of chatbots in the future as well as the potential benefits of chatbots for millennial users in particular.14 although there is no shortage of theoretical research, there is very limited literature assessing the extent to which chatbot technologies are currently being employed by academic libraries for reference services, particularly in canada. case studies have explored the introduction of chatbots into specific american academic libraries, as well as public libraries, but there do not seem to be comparable studies published for canadian post-secondary institutions.15 although research has examined major canadian research libraries’ incorporation of ai in other areas, such as institutional strategic plans and library programming, research is lacking in the field of library adoption of chatbots for reference or customer service purposes in canada.16 in this way, research on chatbot use in libraries might be lagging behind research investigating the current use of other ai applications in academic libraries. topics such as the use of ai to analyze transcripts of communication between librarians and users have been examined.17 with recent advances in nlp, such as the launch of chatgpt, which could have enormous impacts on education overall, it is a good time to shift focus from theorizing about the effects of chatbots in library spaces and begin assessing their use and impact.18 this is especially important given the significant professional and ethical implications these technologies may have for academic librarianship.19 information technology and libraries december 2023 reference chatbots in canadian academic libraries 3 guy, pival, lewis, and groome methods based on the literature review, we identified two key research questions: 1. to what extent, if any, are academic libraries in canada employing chatbots for reference services? 2. what can be determined about the use of chatbots for reference service in academic libraries in canada? an exploratory data analysis approach was used to address the above research questions. between january and february 2023, the authors visited 106 academic library websites. libraries were selected by consulting the canadian library directory and filtering for university libraries.20 information was collected from each library website around the use of chatbots and live chat services offered by each library and recorded in a spreadsheet. to determine whether a chatbot service was offered, the authors began by visually searching the library homepage for a chat text box or icon. if a chat service was not immediately obvious, the authors looked for a webpage outlining library services or equivalent page. if a chat option was visible, the authors interacted with each chat service widget to see if it indicated the use of ai or a human on the other end. if unclear, we asked via the text box. when a chatbot service was offered, we determined the software vendor by viewing the source code of the website. the vendor or platform used to provide live chat service was also recorded. in addition to determining what kind of online reference services were offered, we also recorded information regarding student population and geographic location of the institution, as well as further details around the chatbot implementation, including how the chatbot is introduced, its name, how long it had been in use (if available), and whether the chatbot engages in user initiated dialogue (uid), in which the interaction begins with a user question, or system directed dialogue (sdd), in which a system prompts a user for information.21 in examining whether a chatbot was used elsewhere on campus, we determined that it was unrealistic to look at every page on the university’s website. instead, we visited each institution’s homepage and admissions page, which are common webpages for each institutional website and which have the traffic and volume of user questions to justify a chatbot. when we reviewed the results of our initial scan, we were surprised by the low occurrences of chatbots on academic library websites. collecting and analyzing publicly available data on library websites allowed us to efficiently gather data to create an accurate snapshot of chatbot use for a particular time window. this method of data collection does have some limitations, however, including that we do not have information about whether a chatbot was previously used in an academic library and then discontinued, or insights into the reasoning behind a library ’s decision to use or not use a chatbot for reference. the flexibility of an exploratory approach allowed us to address the later limitation by including a brief case study outlining the reasoning and process used by the authors’ institution, the university of calgary, to integrate a chatbot service. information delivered in this section was gathered from institutional documentation and authors’ firsthand experience. limitations of this approach are that a single case study is being used to explore this process and that biases may exist because of the authors close relationship to the work.22 despite these limitations, the use of a single case study can be appropriate when researchers can provide unique insights.23 therefore, we will include these insights in a case study section to communicate the process taken to launch a chatbot, in the hope that it can supplement our exploration of this topic and be valuable for other researchers. information technology and libraries december 2023 reference chatbots in canadian academic libraries 4 guy, pival, lewis, and groome findings reference chatbots after searching canadian post-secondary library websites for evidence of chatbot reference, we determined that only two out of 106 libraries (1.89%) were currently using a chatbot reference service. both institutions, the university of calgary and mount royal university, are located in calgary, alberta. in both cases, the chatbot was created by ivy.ai, which according to the company is “the leading provider of conversational, artificially intelligent chatbots for higher education.”24 at the university of calgary, ivy.ai chatbots were also used by units on campus other than the library, such as the registrar. during our assessment, we looked for trends in the data that might explain why only two academic libraries are currently using a chatbot. the most obvious similarity is that both institutions are in the same city. the proximity between these two institutions likely means greater potential for the sharing of professional practice ideas at localized professional conferences or through personal connections. this proximity may have impacted the clustering of chatbot use in this one city. the fact that both institutions use ivy.ai is another similarity which might be explained by nearby libraries having a greater awareness of what the other institution is doing, although this is speculation. this trend might suggest that adoption of chatbots may accelerate once p recedent has been established and awareness of successful chatbot integration spreads to other institutions. further research could involve interviewing academic library leadership to compare what factors they consider when it comes to whether or not to integrate chatbot services. given the increasing popularity of chatbots, it is surprising that so few academic libraries in canada are employing chatbots for reference services. the literature offers a few possible explanations for this. according to kaushal and yadav, risks associated with accessibility for users, system restrictions, and privacy have slowed the adoption of chatbot technologies in academic libraries.25 we can speculate as to other contributing factors, including lack of familiarity with these technologies among library staff, cost, insufficient need for reference support due to a manageable volume of questions, or that ai companies may not have sought out academic libraries as potential customers in a significant way. the relatively slow adoption of ai for reference service can also be compared to the library profession’s initial hesitancy to incorporate internet searching in library reference. nelson and irwin provided a thorough breakdown of the impacts of the rise of internet search on the occupational identity of librarians.26 the authors determined that there can be hesitancy to adopt new technology when a profession has a well-established identity, a technology emerges designed to perform a task that overlaps with that identity, and the method used by that technology contradicts the general idea of how a task should be done by members of that profession. 27 when these three factors combine, the professional’s “mastery of the existing approach encourages them to devalue solutions that do not match this approach.”28 according to nelson and irwin, in the early days of the internet, librarians were very motivated by “the belief that internet search was not the best way to help patrons.”29 delays in chatbot adoption may be motivated by similar feelings now. library staff may understandably feel that current practices meet the needs of patrons better than these technologies currently can. live chat service out of 106 academic libraries studied, 78 (73.58%) offered a live chat service, connecting users with library staff online. we found that some libraries give users the option to text questions, but we did not consider this live chat service because it is unclear whether responses to texts happen live or if library staff respond to those queries later, as they might with an emailed question. of the information technology and libraries december 2023 reference chatbots in canadian academic libraries 5 guy, pival, lewis, and groome 78 libraries offering live agent chat reference, there were three predominant platforms in use. forty-three (53.85%) of the libraries that offered live chat used some version of libraryh3lp, either individually or in a consortial environment; 18 (21.79%) used libchat from springshare; and 12 (15.38%) used askaway, a branded service for libraries in the british columbian electronic library network (supported by the libraryh3lp web client). less common live chat platforms were tawk.to, zendesk, facebook messenger, skylerai live!, and ivy.ai (ivy.ai can be used for both live chat and chatbot services), which were used by one institution each. these findings suggest that the majority of academic libraries in canada are offering live chat as a remote reference service. although we do not have data on how popular this approach was before the onset of the covid-19 pandemic, we can assume that the transition to off-campus learning made this service particularly important for many institutions. one of the main benefits of both live chat services and chatbots is that students can access them from anywhere they have an internet connection. it is possible that live chat services meet the user's need for remote reference support and, thus, institutions do not feel compelled to introduce a chatbot at this time. further research could explore the relationship between live chat services and the covid-19 pandemic in greater detail, including how it has impacted decisions around service delivery. integrating or separating live agent chat and chatbot reference services the two libraries studied that provided both a chatbot and live chat service exemplify two different approaches to providing these services. in the case of the university of calgary, two different platforms were used to provide the chatbot and live agent chat services. the chat with library staff is provided through springshare’s libchat platform, and the chatbot is an ivy.ai system. in contrast, at mount royal university, a single ivy.ai system is used for both, with the chatbot responding after hours and a live chat agent responding the rest of the time. interviewing staff at these institutions to determine their reasoning for integrating or not integrating these two services is beyond the scope of this paper. we can, however, speculate as to possible factors that contribute to these decisions. for example, libraries may want separate systems to very clearly distinguish which service is being delivered, so users understand whether they are communicating with a library staff member or a chatbot. separate systems also give users the option of communicating with a chatbot rather than a human, which previous research suggests may be preferable for some users with relatively straightforward questions.30 a potential benefit of using an integrated system is that the pathway to getting library assistance is always the same for users, and the conversation can be continuous even after it is transferred to a human. case study in previous sections, we discussed factors that may contribute to an academic library ’s decision to integrate or not integrate a chatbot on their library website. to pursue this analysis further, the following case study will provide an example of the authors’ institution’s reasoning and processes for offering a chatbot as part of their reference services. the incorporation of chatbot technology was a logical next step in the evolution of library service for the university of calgary library. having offered live chat service since 2010, proactive live chat was introduced in november 2018, using a pop-up that invited users to talk to a staff member via instant message when they lingered on a library webpage for more than 30 seconds. this immediately tripled the number of incoming queries. upon closer analysis of the live chat transcripts, there was a high demand for chat service outside of regular service hours. additionally, a significant number of questions were frequently asked, for example, basic reference information technology and libraries december 2023 reference chatbots in canadian academic libraries 6 guy, pival, lewis, and groome and directional questions such as “what is a peer reviewed article?,” “what are your hours?,” or “how do i book a workroom?” during this period, the library’s associate university librarian of technology was investigating various methods and technologies to support the staff answering live chat queries. discussions with university of calgary it revealed that the registrar’s office was developing a request for proposal for a chatbot and the library was able to take advantage of this same initiative in january 2021. a few months later, a team of library staff was formed to work with the software vendor. the library website was scraped for training data, and the vendor worked closely with the library team to test and calibrate the chatbot. in august 2021, the library went live with taylor rex (t-rex for short), an eponym for the taylor family digital library. by taking the initial request and triaging the information, the chatbot provided directional and basic reference support and helped library chat operators manage the number of incoming queries. in this example, the university of calgary’s decision to introduce a chatbot came out of a need to answer faqs, meet user needs outside of regular operating hours, and assist staff with a large volume of questions. with a similar approach being pursued elsewhere on campus, timing and institutional support helped move the initiative forward. since introducing the chatbot, live chat statistics have dropped significantly at the university of calgary and striking a balance between chatbot vs. live chat entrance points across the library’s web properties is an ongoing priority. conclusion and next steps our findings suggest that few academic libraries in canada were using chatbot technologies to provide reference services at the beginning of 2023. anecdotally, the authors are aware of at least one academic library declaring itself a “bot-free zone” on social media. while it seems very likely that more libraries will adopt this technology in the near future, there may be a backlash against it, and a renewed entrenchment of personalized human services. this research provides valuable insights into the current state of ai-assisted chatbots in academic libraries in canada. this information will be useful for library professionals considering implementing this technology in their institutions and for researchers studying the use of ai in library services. suggested research areas for the future include similar analysis in different regions and library types, ethical and quality considerations in the use of chatbots for reference service, and professional considerations and implications for these technologies. endnotes 1 ferliana dwitama and andre rusli, “user stories collection via interactive chatbot

services case study conclusion and next steps endnotes guest editorial | hirst 179 o rganization structure and reorganization are never exciting topics. the world rarely pauses to take a deep breath or offer a round of applause when an organization adds a new committee or decides to split into subgroups. however, organizations frequently inform the patterns and processes of change—as well as no change. recently, the ex libris users of north america (eluna) group reorganized. processes and outcomes were similar to those i observed many years before when the library information and technology association (lita) restructured, and i labeled the process litaish. john webb subsequently asked me to elaborate through an information technologies and libraries (ital) editorial. ■ lita—an organizational recap in 1981, lita launched a bold reorganization. sections and committees were abolished and a new structure, the interest group, was created with the hope of significant benefits to the organization. the final report of the long-range plan implementation committee of may 29, 1984, stated: the main thrust of the reorganization . . . was the establishment and encouragement of interest groups, which were intended to reflect topics of current interest to members and to have a structure which allows for easy creation and easy elimination as interests and technology change. interest groups could be formed . . . from as few as ten lita members and were empowered to plan and present programs, institutes, and preconferences . . . linda knutson, who became executive director of lita in february 1987, “has . . . been impressed by the increase in the level of participation and by the tremendous energy that the players have; they want to contribute, and they plunge in with both feet.” these comments are from conversations with linda knutson quoted in “lita’s first twenty-five years: a brief history,” by stephen r. salmon in the march 1993 silver anniversary issue of ital. twenty years later, the lita organization and, specifically, the lita interest groups (igs) continue to provide forums for discussion, create conference programs, institutes, and preconferences. the igs hold the content of the organization with minimal administrative overhead, irregular leadership, and virtually no bylaws. ■ naaug—the deconstruction of a classic model aleph, the ex libris integrated library solution (ils) software, is used in numerous countries. the north american aleph user’s group (naaug) existed from 1999 to 2006. the organization had a reasonably classic structure with a steering committee and ad hoc groups to work on annual software enhancements, focus groups, and conference planning. the organization was very centralized with all appointments to subgroups made by the steering committee. developments outside the ils put pressure on naaug to reorganize. ex libris was offering numerous new products, some of which complemented, some of which were independent of the ils. as with any organization, there was some pressure to retain all or part of the status quo from those who were hesitant to change or change radically. leaders, including myself, were cautious, always questioning whether new developments would work and be effective. ■ eluna emerges the new ex libris users’ organization, eluna, is composed of the steering committee, product groups (pgs), and interest groups (igs). i was intrigued with the formation of eluna igs and believe that this structure was an offspring of the lita igs. the eluna igs have very little bureaucracy to hinder the creativity and energy that lita wanted to capture. there is no minimum number of participants in an eluna ig, the creation of which can be proposed by any single individual. each group must write a brief annual report, have a contact person whose name and e-mail is posted on the web site, and may have an optional electronic discussion list. the groups can meet at the annual conference or anywhere they choose and a virtual ig is not discouraged. the igs may get involved in product enhancements, but it is fine to leave this work to the pgs. currently, igs are organized around such areas as function, type of library, and particular software. some examples: ■ data representation (special scripts) ■ law ■ edi ■ music ■ government publications ■ shared systems (consortia) ■ ill ■ sql guest editorial: organizational structure— yesterday informs the present donna hirst donna l. hirst (donna-hirst@uiowa.edu) is project coordinator, library information technology, university of iowa libraries, and a member of the ital editorial board. 180 information technology and libraries | december 2006 ■ large research libraries ■ z39.50 ■ what happens next? the eluna structures of steering committee, pgs, and igs are off to a good start. because each of these is empowered to work independently, a communication matrix needs to be put into place so that all interested or affected parties are adequately informed. in the future, a process will need to be created to identify groups that need to be disbanded. lita solved this problem with the periodic renewal process. in eluna, the contact person may be able to assume this responsibility. we live in an age where “opening” offers a context for change. opening implies new possibilities and few restrictions. open systems . . . open access . . . open source. it appears to me that eluna is continuing a tradition that lita began twenty-five years ago with an open organization. put people into a group, stir lightly, and watch what comes out of the pot. ■ microsoft word june_ital_deodato_final.docx evaluating  web-­‐scale  discovery:     a  step-­‐by-­‐step  guide              joseph  deodato     information  technology  and  libraries  |  june  2015             19   abstract   selecting a web-scale discovery service is a large and important undertaking that involves a significant investment of time, staff, and resources. finding the right match begins with a thorough and carefully planned evaluation process. to be successful, this process should be inclusive, goal-oriented, datadriven, user-centered, and transparent. the following article offers a step-by-step guide for developing a web-scale discovery evaluation plan rooted in these five key principles based on best practices synthesized from the literature as well as the author’s own experiences coordinating the evaluation process at rutgers university. the goal is to offer academic libraries that are considering acquiring a web-scale discovery service a blueprint for planning a structured and comprehensive evaluation process. introduction as  the  volume  and  variety  of  information  resources  continue  to  multiply,  the  library  search   environment  has  become  increasingly  fragmented.  instead  of  providing  a  unified,  central  point  of   access  to  its  collections,  the  library  offers  an  assortment  of  pathways  to  disparate  silos  of   information.  to  the  seasoned  researcher  familiar  with  these  resources  and  experienced  with  a   variety  of  search  tools  and  strategies,  this  maze  of  options  may  be  easy  to  navigate.  but  for  the   novice  user  who  is  less  accustomed  to  these  tools  and  even  less  attuned  to  the  idiosyncrasies  of   each  one’s  own  unique  interface,  the  sheer  amount  of  choice  can  be  overwhelming.  even  if  the   user  manages  to  find  their  way  to  the  appropriate  resource,  figuring  out  how  to  use  it  effectively   becomes  yet  another  challenge.  this  is  at  least  partly  due  to  the  fact  that  the  expectations  and   behaviors  of  today’s  library  users  have  been  profoundly  shaped  by  their  experiences  on  the  web.   popular  sites  like  google  and  amazon  offer  simple,  intuitive  interfaces  that  search  across  a  wide   range  of  content  to  deliver  immediate,  relevant,  and  useful  results.  in  comparison,  library  search   interfaces  often  appear  antiquated,  confusing,  and  cumbersome.  as  a  result,  users  are  increasingly   relying  on  information  sources  that  they  know  to  be  of  inferior  quality,  but  are  simply  easier  to   find.  as  luther  and  kelly  note,  the  biggest  challenge  academic  libraries  face  in  today’s  abundant   but  fragmented  information  landscape  is  “to  offer  an  experience  that  has  the  simplicity  of   google—which  users  expect—while  searching  the  library’s  rich  digital  and  print  collections— which  users  need.”1  in  an  effort  to  better  serve  the  needs  of  these  users  and  improve  access  to   library  content,  libraries  have  begun  turning  to  new  technologies  capable  of  providing  deep   discovery  of  their  vast  scholarly  collections  from  a  single,  easy-­‐to-­‐use  interface.  these   technologies  are  known  as  web-­‐scale  discovery  services.     joseph  deodato  (jdeodato@rutgers.edu)  is  digital  user  services  librarian  at  rutgers  university,   new  brunswick,  new  jersey.     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   20   to  paraphrase  hoeppner,  a  web-­‐scale  discovery  service  is  a  large  central  index  paired  with  a   richly  featured  user  interface  providing  a  single  point  of  access  to  the  library’s  local,  open  access,   and  subscription  collections.2  unlike  federated  search,  which  broadcasts  queries  in  real-­‐time  to   multiple  indexes  and  merges  the  retrieved  results  into  a  single  set,  web-­‐scale  discovery  relies  on  a   central  index  of  preharvested  data.  discovery  vendors  contract  with  content  providers  to  index   their  metadata  and  full-­‐text  content,  which  is  combined  with  the  library's  own  local  collections   and  made  accessible  via  a  unified  index.  this  approach  allows  for  rapid  search,  retrieval,  and   ranking  of  a  broad  range  of  content  within  a  single  interface,  including  materials  from  the  library’s   catalog,  licensed  databases,  institutional  repository,  and  digital  collections.  web-­‐scale  discovery   services  also  offer  a  variety  of  features  and  functionality  that  users  have  come  to  expect  from   modern  search  tools.  features  such  as  autocorrect,  relevance  ranking,  and  faceted  browsing  make   it  easier  for  users  to  locate  library  materials  more  efficiently  while  enhanced  content  such  as  cover   images,  ratings,  and  reviews  offer  an  enriched  user  experience  while  providing  useful  contextual   information  for  evaluating  results.   commercial  discovery  products  entered  the  market  in  2007  at  a  time  when  academic  libraries   were  feeling  pressure  to  compete  with  newer  and  more  efficient  search  tools  like  google  scholar.   to  improve  the  library  search  experience  and  stem  the  seemingly  rising  tide  of  defecting  users,   academic  libraries  were  quick  to  adopt  discovery  solutions  that  promised  improved  access  and   increased  usage  of  their  collections.  yet  despite  the  significant  impact  these  technologies  have  on   staff  and  users,  libraries  have  not  always  undertaken  a  formal  evaluation  process  when  selecting  a   discovery  product.  some  were  early  adopters  that  selected  a  product  at  a  time  when  there  few   other  options  existed  on  the  market.  others  served  as  beta  sites  for  particular  vendors  or  simply   chose  the  product  offered  by  their  existing  ils  or  federated  search  provider.  still  others  had  a   selection  decision  made  for  them  by  their  library  director  or  consortium.  however,  despite  rapid   adoption,  the  web-­‐scale  discovery  market  has  only  just  begun  to  mature.  as  products  emerge  from   their  initial  release  and  more  information  about  them  becomes  available,  the  library  community   has  gained  a  better  understanding  of  how  web-­‐scale  discovery  services  work  and  their  particular   strengths  and  weaknesses.  in  fact,  some  libraries  that  have  already  implemented  a  discovery   service  are  currently  considering  switching  products.  whether  your  library  is  new  to  the   discovery  marketplace  or  poised  for  reentry,  this  article  is  intended  to  help  you  navigate  to  the   best  product  to  meet  the  needs  of  your  institution.  it  covers  the  entire  process  from  soup  to  nuts   from  conducting  product  research  and  drafting  organizational  requirements  to  setting  up  local   trials  and  coordinating  user  testing.  by  combining  guiding  principles  with  practical  examples,  this   article  aims  to  offer  an  evaluation  model  rooted  in  best  practices  that  can  be  adapted  by  other   academic  libraries.   literature  review   as  the  adoption  of  web-­‐scale  discovery  services  continues  to  rise,  a  growing  body  of  literature  has   emerged  to  help  librarians  evaluate  and  select  the  right  product.  moore  and  greene  provide  a     information  technology  and  libraries  |  june  2015     21   useful  review  of  this  literature  summarizing  key  trends  such  as  the  timeframe  for  evaluation,  the   type  of  staff  involved,  the  products  being  evaluated,  and  the  methods  and  criteria  used  by   evaluators.3  much  of  the  early  literature  on  this  subject  focuses  on  comparisons  of  product   features  and  functionality.  rowe,  for  example,  offers  comparative  reviews  of  leading  commercial   services  on  the  basis  of  criteria  such  as  content,  user  interface,  pricing,  and  contract  options.4  yang   and  wagner  compare  commercial  and  open  source  discovery  tools  using  a  checklist  of  user   interface  features  that  includes  search  options,  faceted  navigation,  result  ranking,  and  web  2.0   features.5  vaughan  provides  an  in-­‐depth  look  at  discovery  services  that  includes  an  introduction   to  key  concepts,  detailed  profiles  on  each  major  service  provider,  and  a  list  of  questions  to   consider  when  selecting  a  product.6  a  number  of  authors  have  provided  useful  lists  of  criteria  to   help  guide  product  evaluations.  hoeppner,  for  example,  offers  a  list  of  key  factors  such  as  breadth   and  depth  of  indexing,  search  and  refinement  options,  branding  and  customization,  and  tools  for   saving,  organizing,  and  exporting  results.7  luther  and  kelly  and  hoseth  provide  a  similar  list  of   end-­‐user  features  but  also  include  institutional  considerations  such  as  library  goals,  cost,  vendor   support,  and  compatibility  with  existing  technologies.8     while  these  works  are  helpful  for  getting  a  better  sense  of  what  to  look  for  when  shopping  for  a   web-­‐scale  discovery  service,  they  do  not  offer  guidance  on  how  to  design  a  structured  evaluation   plan.  indeed,  many  library  evaluations  have  tended  to  rely  on  what  can  be  described  as  the   checklist  method  of  evaluation.  this  typically  involves  creating  a  checklist  of  desirable  features   and  then  evaluating  products  on  the  basis  of  whether  they  provide  these  features.  for  example,  in   developing  an  evaluation  process  for  rider  university,  chickering  and  yang  compiled  a  list  of   sixteen  user  interface  features,  examined  live  product  installations,  and  ranked  each  product   according  to  the  number  of  features  offered.9  brubaker,  leach-­‐murray,  and  parker  employed  a   similar  process  to  select  a  discovery  service  for  the  twenty-­‐three  members  of  the  private   academic  library  network  of  indiana  (palni).10  these  types  of  evaluations  suffer  from  a  number   of  limitations.  first,  they  tend  to  rely  on  vendor  marketing  materials  or  reviews  of   implementations  at  other  institutions  rather  than  local  trials  and  testing.  second,  product   requirements  are  typically  given  equal  weight  rather  than  prioritized  according  to  importance.   third,  these  requirements  tend  to  focus  predominantly  on  user  interface  features  while  neglecting   equally  important  back  end  functionality  and  institutional  considerations.  finally,  these   evaluations  do  not  always  include  input  or  participation  from  library  staff,  users,  and  stakeholders.   the  first  published  work  to  offer  a  structured  model  for  evaluating  web-­‐scale  discovery  services   was  vaughan’s  “investigations  into  library  web-­‐scale  discovery  services.”11  vaughan  outlines  the   evaluation  process  employed  at  university  of  nevada,  las  vegas  (unlv),  which,  in  addition  to   developing  a  checklist  of  product  requirements,  also  included  staff  surveys,  interviews  with  early   adopters,  vendor  demonstrations,  and  coverage  analysis.  the  author  also  provides  several  useful   appendixes  with  templates  and  documents  that  librarians  can  use  to  guide  their  own  evaluation.   vaughan’s  work  also  appears  in  popp  and  dallis’

 well  as  programs  in   professional  and  continuing  education.  the  university  is  distributed  across  three  regional   campuses  serving  more  than  65,000  students  and  24,000  faculty  and  staff.  the  rutgers  university   libraries  comprise  twenty-­‐six  libraries  and  centers  with  a  combined  collection  of  more  than  10.5   million  print  and  electronic  holdings.  the  libraries’  collections  and  services  support  the   curriculum  of  the  university’s  many  degree  programs  as  well  as  advanced  research  in  all  major   academic  disciplines.   in  january  2013,  the  libraries  appointed  a  cross-­‐departmental  team  to  research,  evaluate,  and   recommend  the  selection  of  a  web-­‐scale  discovery  service.  the  impetus  for  this  initiative  derived   from  a  demonstrated  need  to  improve  the  user  search  experience  on  the  basis  of  data  collected   over  the  last  several  years  through  ethnographic  studies,  user  surveys,  and  informal  interactions   at  the  reference  desk  and  in  the  classroom.  users  reported  high  levels  of  dissatisfaction  with   existing  library  search  tools  such  as  the  catalog  and  electronic  databases,  which  they  found   confusing  and  difficult  to  navigate.  above  all,  users  demanded  a  simple,  intuitive  starting  point   from  which  to  search  and  access  the  library’s  collections.  accordingly,  the  libraries  began   investigating  ways  to  improve  access  with  web-­‐scale  discovery.  the  evaluation  team  examined   offerings  from  four  leading  web-­‐scale  discovery  providers,  including  ebsco  discovery  service,   proquest’s  summon,  ex  libris’  primo,  and  oclc’s  worldcat  local.  the  process  lasted   approximately  nine  months  and  included  extensive  product  and  user  research,  vendor   demonstrations,  an  rfp,  reference  interviews,  trials,  surveys,  and  product  testing.  see  appendix  a   for  an  overview  of  the  evaluation  plan.     information  technology  and  libraries  |  june  2015     23   by  the  time  it  began  its  evaluation,  rutgers  was  already  a  latecomer  to  the  discovery  game.  most  of   our  peers  had  already  been  using  web-­‐scale  discovery  services  for  many  years.  however,  rutgers’   less-­‐than-­‐stellar  experience  with  federated  search  had  led  it  to  adopt  a  more  cautious  attitude   toward  the  latest  and  greatest  of  library  “holy  grails.”  this  wait-­‐and-­‐see  approach  proved  highly   beneficial  in  the  end  as  it  allowed  time  for  the  discovery  market  to  mature  and  gave  the  evaluation   team  an  opportunity  to  learn  from  the  successes  and  failures  of  early  adopters.  in  planning  its   evaluation,  the  rutgers  team  was  able  to  draw  on  the  experiences  of  earlier  pioneers  such  as   unlv,  penn  state,  the  university  of  chicago,  and  the  university  of  michigan.  it  was  on  the   metaphorical  shoulders  of  these  library  giants  that  rutgers  built  its  own  successful  evaluation   process.  what  follows  is  a  step-­‐by-­‐step  guide  for  evaluating  and  selecting  a  web-­‐scale  discovery   service  on  the  basis  of  best  practices  synthesized  from  the  literature  as  well  as  the  author’s  own   experiences  coordinating  the  evaluation  process  at  rutgers.  given  the  rapidly  changing  nature  of   the  discovery  market,  the  focus  of  this  article  is  on  the  process  rather  than  the  results  of  rutgers’   evaluation.  while  the  results  will  undoubtedly  be  outdated  by  the  time  this  article  goes  to  press,   the  process  is  likely  to  remain  relevant  and  useful  for  years  to  come.   form  an  evaluation  team   the  first  step  in  selecting  a  web-­‐scale  discovery  service  is  appointing  a  team  that  will  be   responsible  for  conducting  the  evaluation.  composition  of  the  team  will  vary  depending  on  local   practice  and  staffing,  but  should  include  representatives  from  a  broad  cross  section  of  library   units,  including  collections,  public  services,  technical  services,  and  systems.  institutions  with   multiple  campuses,  schools,  or  library  branches  will  want  make  sure  the  interests  of  these   constituencies  are  also  represented.  if  feasible,  the  library  should  consider  including  actual  users   on  the  evaluation  team.  these  may  be  members  of  an  existing  user  advisory  board  or  recruits   from  among  the  library’s  student  employees  and  faculty  liaisons.  including  users  on  your   evaluation  team  will  keep  the  process  focused  on  user  needs  and  ensure  that  the  library  selects   the  best  product  to  meet  them.   there  are  many  reasons  for  establishing  an  inclusive  evaluation  team.  first,  discovery  tools  have   broad  implications  for  a  wide  range  of  library  services  and  functions.  therefore  a  diversity  of   library  expertise  is  required  for  an  informed  and  comprehensive  evaluation.  reference  and   instruction  librarians  will  need  to  evaluate  the  functionality  of  the  tool,  the  quality  of  results,  and   its  role  in  the  research  process.  collections  staff  will  need  to  assess  scope  of  coverage  and   congruency  with  the  library’s  existing  subscriptions.  access  services  will  need  to  assess  how  the   tool  handles  local  holdings  information  and  integrates  with  borrowing  and  delivery  services  like   interlibrary  loan.  catalogers  will  need  to  evaluate  metadata  requirements  and  procedures  for   harvesting  local  records.  it  staff  will  need  to  assess  technical  requirements  and  compatibility  with   existing  infrastructure  and  systems.   second,  depending  on  the  size  and  goals  of  the  institution,  the  product  may  be  expected  to  serve  a   wide  community  of  users  with  different  needs,  skill  levels,  and  academic  backgrounds.  large     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   24   universities  that  include  multiple  schools,  offer  various  degree  programs,  or  have  specialized   programs  like  law  or  medicine  will  need  to  determine  if  and  how  a  new  discovery  tool  will  address   the  needs  of  all  these  users.  it  is  important  that  the  composition  of  the  evaluation  team  adequately   represents  the  interests  of  the  different  user  groups  the  tool  is  intended  to  serve.  the  evaluation  at   rutgers  was  conducted  by  a  cross-­‐departmental  team  of  fifteen  members  and  included  experts   from  a  variety  of  library  units  and  representatives  from  all  campuses.   finally,  because  web-­‐scale  discovery  brings  such  profound  changes  to  staff  and  user  workflows,   decisions  regarding  selection  and  implementation  are  often  fraught  with  controversy.  as  noted,   discovery  tools  impact  a  wide  range  of  library  services  and  therefore  require  careful  evaluation   from  the  perspectives  of  multiple  stakeholders.  furthermore,  these  tools  dramatically  change  the   nature  of  library  research,  and  not  everyone  in  your  organization  may  view  this  change  as  being   for  the  better.  despite  growing  rates  of  adoption,  debates  over  the  value  and  utility  of  web-­‐scale   discovery  continue  to  divide  librarians.18  according  to  one  survey,  securing  staff  buy-­‐in  is  the   biggest  challenge  academic  libraries  face  when  implementing  a  web-­‐scale  discovery  service.19   ensuring  broad  involvement  early  in  the  process  will  help  to  secure  organizational  buy-­‐in  and   support  for  the  selected  product.   while  broad  representation  is  important,  having  a  large  and  diverse  team  can  sometimes  slow   down  the  process;  schedules  can  be  difficult  to  coordinate,  members  may  have  competing  views  or   demands  on  their  time,  meetings  can  lose  focus  or  wander  off  topic,  etc.  the  more  members  on   your  evaluation  team,  the  more  difficult  the  team  may  be  to  manage.  one  strategy  for  managing  a   large  group  might  be  to  create  a  smaller,  core  team  with  all  other  members  serving  on  an  ad  hoc   basis.  the  core  team  functions  as  a  steering  committee  to  manage  the  project  and  calls  on  the  ad   hoc  members  at  different  stages  in  the  evaluation  process  where  their  input  and  expertise  is   needed.  another  strategy  would  be  to  break  the  larger  group  into  several  functional  teams,  each   responsible  for  evaluating  specific  aspects  of  the  discovery  tool.  for  example,  one  team  might   focus  on  functionality,  another  on  technology,  a  third  on  administration,  etc.  this  method  also  has   the  advantage  of  distributing  the  workload  among  team  members  and  breaking  down  a  complex   evaluation  process  into  discrete,  more  manageable  parts.   like  any  other  committee  or  taskforce,  your  evaluation  team  should  have  a  charge  outlining  its   responsibilities,  timetable  of  deliverables,  reporting  structure,  and  membership.  the  charge   should  also  include  a  vision  or  goals  statement  that  explicitly  states  the  underlying  assumptions   and  premises  of  the  discovery  tool,  its  purpose,  and  how  it  supports  the  library’s  larger  mission  of   connecting  users  with  information.20  although  frequently  highlighted  in  the  literature,  the   importance  of  defining  institutional  goals  for  discovery  is  often  overlooked  or  taken  for  granted.21   having  a  vision  statement  is  crucial  to  the  success  of  the  project  for  multiple  reasons.  first,  it   frames  the  evaluation  process  by  establishing  mutually  agreed-­‐upon  goals  and  priorities  for  the   product.  before  the  evaluation  can  begin,  the  team  must  have  a  clear  understanding  of  what   problems  the  discovery  service  is  expected  to  solve,  who  it  is  intended  to  serve,  and  how  it     information  technology  and  libraries  |  june  2015     25   supports  the  library’s  strategic  goals.  is  the  service  primarily  intended  for  undergraduates,  or  is  it   also  expected  to  serve  graduate  students  and  faculty?  is  it  a  one-­‐stop  shop  for  all  information   needs,  a  starting  point  in  a  multi-­‐step  research  process,  or  merely  a  useful  tool  for  general  and   interdisciplinary  research?  second,  having  a  clear  vision  for  the  product  will  help  guide   implementation  and  assessment.  it  will  not  only  help  the  library  decide  how  to  configure  the   product  and  what  features  to  prioritize,  but  also  offer  explicit  benchmarks  by  which  to  evaluate   performance.  finally,  aligning  web-­‐scale  discovery  with  the  library’s  strategic  plan  will  help  put   the  project  in  wider  context  and  secure  buy-­‐in  across  all  units  in  the  organization.  having  a  clear   understanding  of  how  the  product  will  be  integrated  with  and  support  other  library  services  will   help  minimize  common  misunderstandings  and  ensure  wider  adoption.   educate  library  stakeholders   despite  the  quick  maturation  and  adoption  of  web-­‐scale  discovery  services,  these  technologies  are   still  relatively  new.  many  librarians  in  your  organization,  including  those  on  the  evaluation  team,   may  only  possess  a  cursory  understanding  of  what  these  tools  are  and  how  they  function.  creating   an  inclusive  evaluation  process  requires  having  an  informed  staff  that  can  participate  in  the   discussions  and  decision-­‐making  processes  leading  to  product  selection.  therefore  the  first  task  of   your  evaluation  team  should  be  to  educate  themselves  and  their  colleagues  on  the  ins  and  outs  of   web-­‐scale  discovery  services.  this  should  include  performing  a  literature  review,  collecting   information  about  products  currently  on  the  market,  and  reviewing  live  implementations  at  other   institutions.   at  rutgers,  the  evaluation  team  conducted  an  extensive  literature  review  that  resulted  in   annotated  bibliography  covering  all  aspects  of  web-­‐scale  discovery,  including  general   introductions,  product  reviews,  and  methodologies  for  evaluation,  implementation,  and   assessment.  all  team  members  were  encouraged  to  read  this  literature  to  familiarize  themselves   with  relevant  terminology,  products,  and  best  practices.  the  team  also  collected  product   information  from  vendor  websites  and  reviewed  live  implementations  at  other  institutions.  in  this   way,  members  were  able  to  familiarize  themselves  with  the  different  features  and  functionality   offered  by  each  vendor.   once  the  team  has  done  its  research,  it  can  begin  sharing  its  findings  with  the  rest  of  the  library   community.  vaughan  recommends  establishing  a  quick  and  easy  means  of  disseminating   information  such  as  an  internal  staff  website,  blog,  or  wiki  that  staff  can  visit  on  their  own  time.22   the  rutgers  team  created  a  private  libguide  that  served  as  a  central  repository  for  all  information   related  to  the  evaluation  process,  including  a  brief  introduction  to  web-­‐scale  discovery,   information  about  each  product,  recorded  vendor  demonstrations,  links  to  live  implementations,   and  an  annotated  bibliography.  also  included  was  information  about  the  team’s  ongoing  work,   including  the  group’s  charge,  timeline,  meeting  minutes,  and  reports.  in  addition  to  maintaining  an   online  presence,  the  team  also  held  a  series  of  public  forums  and  workshops  to  educate  staff  about   the  nature  of  web-­‐scale  discovery  as  well  as  provide  updates  on  the  evaluation  process  and     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   26   respond  to  questions  and  concerns.  by  providing  staff  with  a  foundation  for  understanding  web-­‐ scale  discovery  and  the  process  by  which  these  products  were  to  be  evaluated,  the  team  sought  to   maximize  the  engagement  and  participation  of  the  larger  library  community.   schedule  vendor  demonstrations   once  everyone  has  a  conceptual  understanding  of  what  web-­‐scale  discovery  services  do  and  how   they  work,  it  is  time  to  begin  inviting  onsite  vendor  demonstrations.  these  presentations  give   library  staff  an  opportunity  to  see  these  products  in  action  and  ask  vendors  in-­‐depth  questions.   sessions  are  usually  led  by  a  sales  representative  and  product  manager  and  typically  include  a   brief  history  of  the  product’s  development,  a  demonstration  of  key  features  and  functionality,  and   an  audience  question-­‐and-­‐answer  period.  to  provide  a  level  playing  field  for  comparison,  the   evaluation  team  may  wish  to  submit  a  list  of  topics  or  questions  for  each  vendor  to  address  in   their  presentation.  this  could  be  a  general  outline  of  key  areas  of  interest  identified  by  the   evaluation  team  or  a  list  of  specific  questions  solicited  from  the  wider  library  community.  vaughan   offers  a  useful  list  of  questions  that  librarians  may  wish  to  consider  to  structure  vendor   demonstrations.23  one  tactic  used  by  the  evaluation  team  at  auburn  university  involved  requiring   vendors  to  use  their  products  to  answer  a  series  of  actual  reference  questions.24  this  not  only   precluded  them  from  using  canned  searches  that  might  only  showcase  the  strengths  of  their   products,  but  also  gave  librarians  a  better  sense  of  how  these  products  would  perform  out  in  the   wild  against  real  user  queries.  another  approach  might  be  to  invite  actual  users  to  the   demonstrations.  whether  you  are  fortunate  enough  to  have  users  on  your  evaluation  team  or  able   to  encourage  a  few  library  student  workers  to  attend,  your  users  may  raise  important  questions   that  your  staff  has  overlooked.   vendor  demonstrations  should  only  be  scheduled  after  the  evaluation  team  has  had  an   opportunity  to  educate  the  wider  library  community.  an  informed  staff  will  get  more  out  of  the   demos  and  be  better  equipped  to  ask  focused  questions.  as  vaughan  suggests,  demonstrations   should  be  scheduled  in  close  proximity  (preferably  within  the  same  month)  to  sustain  staff   engagement,  facilitate  retention  of  details,  and  make  it  easier  to  compare  services.25  with  the   vendor’s  permission,  libraries  should  also  consider  recording  these  sessions  and  making  them   available  to  staff  members  who  are  unable  to  attend.  at  the  conclusion  of  each  demonstration,   staff  should  be  invited  to  offer  their  feedback  on  the  presentation  or  ask  any  follow-­‐up  questions.   this  can  be  accomplished  by  distributing  a  brief  paper  or  online  survey  to  the  attendees.   create  an  evaluation  rubric   perhaps  the  most  important  part  of  the  evaluation  process  is  developing  a  list  of  key  criteria  that   will  be  used  to  evaluate  and  compare  vendor  offerings.  once  the  evaluation  team  has  a  better   understanding  of  what  these  products  can  do  and  the  different  features  and  functionality  offered   by  each  vendor,  it  can  begin  defining  the  ideal  discovery  environment  for  its  institution.  this  often   takes  the  form  of  a  list  of  desirable  features  or  product  requirements.  the  process  for  generating     information  technology  and  libraries  |  june  2015     27   these  criteria  tends  to  vary  by  institution.  in  some  cases,  they  are  defined  by  the  team  leader  or   based  on  criteria  used  for  past  technology  purchases.26  in  other  cases,  criteria  are  compiled   through  a  review  of  the  literature.27  in  yet  other  cases,  they  are  developed  and  refined  with  input   from  library  staff  through  staff  surveys  and  meetings.28   one  important  element  missing  from  all  of  these  approaches  is  the  user.  to  ensure  the  evaluation   team  selects  the  best  tool  for  library  users,  product  requirements  should  be  firmly  rooted  in  an   assessment  of  user  needs.  the  university  of  michigan,  for  example,  used  persona  analysis  to   identify  common  user  needs  and  distilled  these  into  a  list  of  tangible  features  that  could  be  used   for  product  evaluation.29  other  tactics  for  assessing  user  needs  and  expectations  might  include   user  surveys,  interviews,  or  focus  groups.  these  tools  can  be  useful  for  gathering  information   about  what  users  want  from  your  web-­‐scale  discovery  system.  however,  these  methods  should  be   used  with  caution,  as  users  themselves  don’t  always  know  what  they  want,  particularly  from  a   product  they  have  never  used.  furthermore,  as  usability  experts  have  pointed  out,  what  users  say   they  want  may  not  be  what  they  actually  need.30  therefore  it  is  important  to  validate  data   collected  from  surveys  and  focus  groups  with  usability  testing.  to  reliably  determine  whether  a   product  meets  the  needs  of  your  users,  it  is  best  to  observe  what  users  actually  do  rather  than   what  they  say  they  do.   if  the  evaluation  team  has  a  short  timeframe  or  is  unable  to  undertake  extensive  user  research,  it   may  be  able  to  develop  product  requirements  on  the  basis  of  existing  research.  at  rutgers,  for   example,  the  libraries’  department  of  planning  and  assessment  conducts  a  standing  survey  to   collect  information  about  users’  opinions  of  and  satisfaction  with  library  services.  the  evaluation   team  was  able  to  use  this  data  to  learn  more  about  what  users  like  and  don’t  like  about  the   library’s  current  search  environment.  the  team  analyzed  more  than  700  user  comments  collected   from  2009  to  2012  related  to  the  library’s  catalog  and  electronic  resources.  comments  were   mapped  to  specific  types  of  features  and  functionality  that  users  want  or  expect  from  a  library   search  tool.  since  most  users  don’t  typically  articulate  their  needs  in  terms  of  concrete  technical   requirements,  some  interpretation  was  required  on  the  part  of  the  evaluation  team.  for  example,   the  average  user  may  not  necessarily  know  what  faceted  browsing  is,  but  a  suggestion  that  there   be  “a  way  to  browse  through  books  by  category  instead  of  always  having  to  use  the  search  box”   could  reasonably  be  interpreted  as  a  request  for  this  feature.  features  were  ranked  in  order  of   importance  by  the  number  of  comments  made  about  it.  some  of  the  most  “requested”  features   included  single  point  of  access,  “smart”  search  functionality  such  as  autocorrect  and  autocomplete,   and  improved  relevance  ranking.   of  course,  user  needs  are  not  the  only  criteria  to  be  considered  when  choosing  a  discovery  service.   organizational  and  staff  needs  must  also  be  taken  into  account.  user  input  is  important  for   defining  the  functionality  of  the  public  interface,  but  staff  input  is  necessary  for  determining  back-­‐ end  functionality  and  organizational  fit.  to  the  list  of  user  requirements,  the  evaluation  team   added  institutional  requirements  related  to  factors  such  as  cost,  coverage,  customizability,  and     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   28   support.  the  team  then  conducted  a  library-­‐wide  survey  inviting  all  staff  to  rank  these   requirements  in  order  of  importance  and  offer  any  additional  requirements  that  should  be   factored  into  the  evaluation.   combining  the  input  from  library  staff  and  users,  the  evaluation  team  drafted  a  list  of  fifty-­‐five   product  requirements  (see  appendix  b),  which  became  the  basis  for  a  comprehensive  evaluation   rubric  that  would  be  used  to  evaluate  and  ultimately  select  a  web-­‐scale  discovery  service.  the   design  of  the  rubric  was  largely  modeled  after  the  one  developed  at  penn  state.31  requirements   were  arranged  into  five  categories:  content,  functionality,  usability,  administration,  and   technology.  each  category  was  allocated  to  a  sub  team  according  to  area  of  expertise  that  would  be   responsible  for  that  portion  of  the  evaluation.  each  requirement  was  assigned  a  weight  according   to  its  degree  of  importance:  3  =  mandatory,  2  =  desired,  1  =  optional.  each  product  was  given  a   score  based  on  how  well  it  met  each  requirement:  3  =  fully  meets,  2  =  partially  meets,  1  =  barely   meets,  0  =  does  not  meet.  the  total  number  of  points  awarded  for  each  requirement  was   calculated  by  multiplying  weight  by  score.  the  final  score  for  each  product  was  calculated  by   summing  up  the  total  number  of  points  awarded  (see  appendix  c).   this  scoring  method  was  particularly  helpful  in  minimizing  the  influence  of  bias  on  the  evaluation   process.  keep  in  mind  that  some  stakeholders  may  possess  personal  preferences  for  or  against  a   particular  product  because  of  current  or  past  relations  with  the  vendor,  their  experiences  with  the   product  while  at  another  institution,  or  their  perception  of  how  the  product  might  impact  their   own  work.  by  establishing  a  set  of  predefined  criteria,  rooted  in  local  needs  and  measured   according  to  clear  and  consistent  standards,  the  team  adopted  an  evaluation  model  that  was  not   only  user-­‐centered,  but  also  allowed  for  a  fair,  unbiased,  and  systematic  evaluation  of  vendor   offerings.  this  is  particularly  important  for  libraries  that  must  go  through  a  formal  procurement   process  to  purchase  a  web-­‐scale  discovery  service.   draft  the  rfp   once  the  evaluation  team  has  defined  its  product  requirements  and  established  a  method  for   evaluating  the  products  in  the  marketplace,  it  can  set  to  work  drafting  a  formal  rfp.  some   institutions  may  be  able  to  forego  the  rfp  process.  others,  like  rutgers,  are  required  to  go  through   a  competitive  bidding  process  for  any  goods  and  services  purchased  over  a  certain  dollar  amount.   the  only  published  model  on  selecting  a  discovery  service  through  the  rfp  process  is  offered  by   freivalds  and  lush.32  the  authors  provide  a  brief  overview  of  the  pros  and  cons  of  using  an  rfp,   describe  the  process  developed  at  penn  state,  and  offer  several  useful  templates  to  help  guide  the   evaluation.   the  rfp  lets  vendors  know  that  the  organization  is  interested  in  their  product,  outlines  the   organization’s  requirements  for  said  product,  and  gives  the  vendors  an  opportunity  to  explain  in   detail  how  their  product  meets  these  requirements.  rfps  are  usually  written  in  collaboration  with     information  technology  and  libraries  |  june  2015     29   your  university’s  purchasing  department  who  typically  provides  a  template  for  this  purpose.  at  a   minimum,  your  rfp  should  include  the  following:   • background  information  about  the  library,  including  size,  user  population,  holdings,  and   existing  technical  infrastructure   • a  description  of  the  product  being  sought,  including  product  requirements,  services  and   support  expected  from  the  vendor,  and  the  anticipated  timeline  for  implementation   • a  summary  of  the  criteria  that  will  be  used  to  evaluate  proposals,  the  deadline  for   submission,  and  the  preferred  format  of  responses   • any  additional  terms  or  conditions  such  as  requiring  vendors  to  provide  references,  onsite   demonstrations,  trial  subscriptions,  or  access  to  support  and  technical  documentation   • information  about  who  to  contact  regarding  questions  related  to  the  rfp   rfps  are  useful  not  only  because  they  force  the  library  to  clearly  articulate  its  needs  for  web-­‐scale   discovery,  but  also  because  they  produce  a  detailed,  written  record  of  product  information  that   can  be  referenced  throughout  the  evaluation  process.  the  key  component  of  rutgers’  rfp  was  a   comprehensive,  135-­‐item  questionnaire  that  asked  vendors  to  spell  out  in  painstaking  detail  the   design,  technical,  and  functional  specifications  of  their  products  (see  appendix  d).  many  of  the   questions  were  either  borrowed  from  the  existing  literature  or  submitted  by  members  of  the   evaluation  team.  all  questions  were  directly  mapped  to  criteria  from  the  team’s  evaluation  rubric.   the  responses  were  used  to  determine  how  well  each  product  met  these  criteria  and  factored  into   product  scoring.  vendors  were  given  one  month  to  respond  to  the  rfp.   interview  current  customers   while  vendor  marketing  materials,  demonstrations,  and  questionnaires  are  important  sources  of   product  information,  vendor  claims  should  not  simply  be  taken  at  face  value.  to  obtain  an   impartial  assessment  of  the  products  under  consideration,  the  evaluation  team  should  reach  out  to   current  customers.  there  are  several  ways  to  identify  current  discovery  service  subscribers.  many   published  overviews  of  web-­‐scale  discovery  services  offer  lists  of  example  implementations  for   each  major  discovery  provider.33  most  vendors  also  provide  a  list  of  subscribers  on  their  website   or  community  wiki  (or  will  provide  one  on  request).  and,  of  course,  there  is  also  marshall   breeding’s  invaluable  website,  library  technology  guides,  which  provides  up-­‐to-­‐date  information   about  technology  products  used  by  libraries  around  the  world.34  the  advanced  search  allows  you   to  filter  libraries  by  criteria  such  as  type,  collection  size,  geographic  area,  and  ils,  thereby  making   it  easier  to  identify  institutions  similar  to  your  own.   as  part  of  the  rfp  process,  all  four  vendors  were  required  to  provide  references  for  three  current   academic  library  customers  of  equivalent  size  and  classification  to  rutgers.  these  twelve   references  were  then  invited  to  take  an  online  survey  asking  them  to  share  their  opinions  of  and   experiences  with  the  product  (see  appendix  e).  the  survey  consisted  of  a  series  of  likert-­‐scale   questions  asking  each  reference  to  rate  their  satisfaction  with  various  functions  and  features  of     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   30   their  discovery  service.  this  was  followed  by  many  in-­‐depth  written  response  questions  regarding   topics  such  as  coverage,  quality  of  results,  interface  usability,  customization,  and  support.  follow-­‐ up  phone  interviews  were  conducted  in  cases  where  additional  information  or  clarification  was   needed.   the  surveys  permitted  the  evaluation  team  to  collect  feedback  from  current  customers  in  a  way   that  was  minimally  obtrusive  while  allowing  for  easy  analysis  and  comparison  of  responses.  it  also   provided  a  necessary  counterbalance  to  vendor  claims  by  giving  the  team  a  much  more  candid   view  of  each  product’s  strengths  and  weaknesses.  the  reference  interviews  helped  highlight   issues  and  areas  of  concern  that  were  frequently  minimized  or  glossed  over  in  communications   with  vendors  such  as  gaps  in  coverage,  inconsistent  metadata,  duplicate  results,  discoverability  of   local  collections,  and  problems  with  known-­‐item  searching.   configure  and  test  local  trials   although  the  evaluation  team  should  strive  to  collect  as  much  product  information  from  as  many   sources  as  possible,  no  amount  of  research  can  effectively  substitute  for  a  good  old-­‐fashioned  trial   evaluation.  conducting  trials  using  the  library’s  own  collections  and  local  settings  is  the  best  way   to  gain  first-­‐hand  insight  into  how  a  discovery  service  works.  for  some  libraries,  the  expenditure   of  time  and  effort  involved  in  configuring  a  web-­‐scale  discovery  service  can  make  the  prospect  of   conducting  trials  prohibitive.  as  a  result,  many  discovery  evaluations  tend  to  rely  on  testing   existing  implementations  at  other  institutions.  however,  this  method  of  evaluation  only  scratches   the  surface.  for  one  thing,  the  evaluation  team  is  only  able  to  observe  the  front-­‐end  functionality   of  the  public  interface.  but  setting  up  a  local  trial  gives  the  library  an  opportunity  to  peak  under   the  hood  and  learn  about  back-­‐end  administration,  explore  configuration  and  customization   options,  attain  a  deeper  understanding  of  the  composition  of  the  central  index,  and  get  a  better   feel  for  what  it  is  like  working  with  the  vendor.  second,  discovery  services  are  highly  customizable   and  the  availability  of  certain  features,  functionality,  and  types  of  content  varies  by  institution.  as   hoeppner  points  out,  no  individual  site  is  capable  of  demonstrating  the  “full  range  of  possibilities”   available  from  any  vendor.35  the  presence  or  absence  of  certain  features  has  as  much  to  do  with   local  library  decisions  as  they  do  with  any  inherent  limitations  of  the  product.  finally,  establishing   trials  gives  the  evaluation  team  an  opportunity  to  see  how  a  particular  discovery  service  performs   within  its  own  local  environment.  the  ability  to  see  how  the  product  works  with  the  library’s  own   records,  ils,  link  resolver,  and  authentication  system  allows  the  team  to  evaluate  the  compatibility   of  the  discovery  service  with  the  library’s  existing  technical  infrastructure.   at  rutgers,  one  of  the  goals  of  the  rfp  was  to  help  narrow  the  pool  of  potential  candidates  from   four  to  two.  the  evaluation  team  was  asked  to  review  vendor  responses  and  apply  the  evaluation   rubric  to  assign  each  a  preliminary  score  on  the  basis  of  how  well  they  met  the  library’s   requirements.  the  two  top-­‐scoring  candidates  would  then  be  selected  for  a  trial  evaluation  that   would  allow  the  team  to  conduct  further  testing  and  make  a  final  recommendation.  however,  after   the  proposals  were  reviewed,  the  scores  for  three  of  the  products  were  so  close  that  the  team     information  technology  and  libraries  |  june  2015     31   decided  to  trial  all  three.  the  one  remaining  product  scored  notably  lower  than  its  competitors   and  was  dropped  from  further  consideration.   configuring  trials  for  three  different  web-­‐scale  discovery  services  was  no  easy  task,  to  be  sure.  an   implementation  team  was  formed  to  work  with  the  vendors  to  get  the  trials  up  and  running.  the   team  received  basic  training  for  each  product  and  was  given  full  access  to  support  and  technical   documentation.  working  with  the  vendors,  the  implementation  team  set  to  work  loading  the   library’s  records  and  configuring  local  settings.  for  the  most  part,  the  trials  were  basic  out-­‐of-­‐the-­‐ box  implementations  with  minimal  customization.  the  vendors  were  willing  to  do  much  of  the   configuration  work  for  us,  but  it  was  important  that  the  team  learn  and  understand  the   administrative  functionality  of  each  product,  as  this  was  an  integral  part  of  the  evaluation  process.   all  vendors  agreed  to  a  three-­‐month  trial  period  during  which  the  evaluation  team  ran  their   products  through  a  series  of  tests  assessing  three  key  areas:  coverage,  usability,  and  relevance   ranking.   the  importance  of  product  testing  cannot  be  overstated.  as  previously  mentioned,  web-­‐scale   discovery  affect  a  wide  variety  of  library  services  and,  in  most  cases,  will  likely  serve  as  the  central   point  of  access  to  the  library’s  collections.  before  committing  to  a  product,  the  library  should  have   an  opportunity  to  conduct  independent  testing  to  validate  vendor  claims  and  ensure  that  their   products  function  according  to  the  library’s  expectations.  to  ensure  that  critical  issues  are   uncovered,  testing  should  strive  to  simulate  as  much  as  possible  the  environment  and  behavior  of   your  users  by  employing  sample  searches  and  strategies  that  they  themselves  would  use.  in  fact,   wherever  possible,  users  should  be  invited  to  participate  in  testing  and  offer  their  feedback  about   the  products  under  consideration.  testing  checklists  and  scripts  must  also  be  created  to  guide   testers  and  ensure  consistency  throughout  the  process.  as  mandernach  and  condit  fagan  point   out,  although  product  testing  is  time-­‐consuming  and  labor-­‐intensive,  it  will  ultimately  save  the   time  of  your  users  and  staff  who  would  otherwise  be  the  first  to  encounter  any  bugs  and  help   avoid  early  unfavorable  impressions  of  the  product.36   the  first  test  the  evaluation  team  conducted  aimed  at  evaluating  the  coverage  and  quality  of   indexing  of  each  discovery  product  (see  appendix  f).  loosely  borrowing  from  methods  employed   at  university  of  chicago,  twelve  library  subject  specialists  were  recruited  to  help  assess  coverage   within  their  discipline.37  each  subject  specialist  was  asked  to  perform  three  search  queries   representing  popular  research  topics  in  their  discipline  and  compare  the  results  from  each   discovery  service  with  respect  to  breadth  of  coverage  and  quality  of  indexing.  in  scoring  each   product,  subject  specialists  were  asked  to  consider  the  following  questions:     • do  the  search  results  demonstrate  broad  coverage  of  the  variety  of  subjects,  formats,   and  content  types  represented  in  the  library’s  collection?     • do  any  particular  types  of  content  seem  to  dominate  the  results  (books,  journal  articles,   newspapers,  book  reviews,  reference  materials,  etc.)?     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   32   • are  the  library’s  local  collections  adequately  represented  in  the  results?   • do  any  relevant  resources  appear  to  be  missing  from  the  search  results  (i.e.,  results   from  an  especially  relevant  database  or  journal)?   • do  item  records  contain  complete  and  accurate  source  information?   • do  item  records  contain  sufficient  metadata  (citation,  subject  headings,  abstracts,  etc.)   to  help  users  identify  and  evaluate  results?   participants  were  asked  to  rate  the  performance  of  each  discovery  service  in  terms  of  coverage   and  indexing  on  a  scale  of  1  to  3  (1  =  poor,  2  =  average,  3  =  good).  although  results  varied  by   discipline,  one  product  received  the  highest  average  scores  in  both  areas.  in  their  observations,   participants  frequently  noted  that  it  appeared  to  have  better  coverage  and  produce  a  greater   variety  of  sources  while  results  from  the  other  two  products  tended  to  be  dominated  by  specific   source  types  like  newspapers  or  reference  books.  the  same  product  was  also  noted  to  have  more   complete  metadata  while  the  other  two  frequently  produced  results  that  lacked  additional   information  like  abstracts  and  subject  terms.     the  second  test  aimed  to  evaluate  the  usability  of  each  discovery  service.  five  undergraduate   students  of  varying  grade  levels  and  areas  of  study  were  invited  to  participate  in  a  task-­‐based   usability  test  (see  appendix  g).  the  purpose  of  the  test  was  to  assess  users’  ability  to  use  these   products  to  complete  common  research  tasks  and  determine  which  product  best  meet  their  needs.   students  were  asked  to  use  all  three  products  to  complete  five  tasks  while  sharing  their  thoughts   aloud.  for  the  purposes  of  testing,  products  were  referred  to  by  letters  (a,  b,  c)  rather  than  name.   because  participants  were  asked  to  complete  the  same  tasks  using  each  product,  it  was  assumed   that  they  their  ability  to  complete  tasks  might  improve  as  the  test  progressed.  accordingly,   product  order  was  randomized  to  minimize  potential  bias.  each  session  lasted  approximately   forty-­‐five  minutes  and  included  a  pre-­‐test  questionnaire  to  collect  background  information  about   the  participant  as  well  as  a  post-­‐test  questionnaire  to  ascertain  their  opinions  on  the  products   being  tested.  because  users  were  being  asked  to  test  three  different  products,  the  number  of  tasks   was  kept  to  a  minimum  and  focused  only  on  basic  product  functionality.  more  comprehensive   usability  testing  would  be  conducted  after  selection  to  help  guide  implementation  and  improve   the  selected  product.     using  each  product,  participants  were  asked  to  find  three  relevant  sources  on  a  topic,  email  the   results  to  themselves,  and  attempt  to  obtain  full  text  for  at  least  one  item.  although  the  team  noted   potential  problems  in  users’  interaction  with  all  of  the  products,  participants  had  slightly  higher   success  rates  with  one  product  over  all  others.  furthermore,  in  the  post-­‐test  questionnaire,  four   out  of  five  users  stated  that  they  preferred  this  product  to  the  other  two,  noting  that  they  found  it   easier  to  navigate,  obtained  more  relevant  results,  and  had  notably  less  difficulty  accessing  full   text.  a  follow-­‐up  question  asked  participants  how  these  products  compared  with  the  search  tools   currently  offered  by  the  library.  almost  all  participants  cited  disappointing  previous  experiences     information  technology  and  libraries  |  june  2015     33   with  library  databases  and  the  catalog  and  suggested  that  a  discovery  tool  might  make  finding   materials  easier.  however,  several  users  also  suggested  that  none  these  tools  were  “perfect.”  and,   while  these  discovery  services  may  have  the  “potential”  to  improve  their  library  experience,  all   could  use  a  good  deal  of  improvement,  particularly  with  returning  relevant  results.    therefore  the  evaluation  team  embarked  on  a  third  and  final  test  of  its  top  three  discovery   candidates,  the  goal  of  which  was  to  evaluate  relevance  ranking.  while  usability  testing  is  helpful   for  highlighting  problems  with  the  design  of  an  interface,  it  is  not  always  the  best  method  for   assessing  the  quality  of  results.  in  user  testing,  students  frequently  retrieved  or  selected  results   that  were  not  relevant  to  the  topic.  it  was  not  always  clear  whether  this  outcome  was  attributable   to  a  flaw  in  product  design  or  to  the  users’  own  ability  to  construct  effective  search  queries  and   evaluate  results.  determining  relevance  is  a  subjective  process  and  one  that  requires  a  certain   level  of  expertise  in  the  relevant  subject  area.  therefore,  to  assess  relevance  ranking  among  the   competing  discovery  services,  the  evaluation  team  turned  once  again  to  its  library  subject   specialists.   echoing  countless  other  user  studies,  our  testing  indicated  that  most  users  do  not  often  scroll   beyond  the  first  page  of  results.  therefore  a  discovery  service  that  harvests  content  from  a  wide   variety  of  different  sources  must  have  an  effective  ranking  algorithm  capable  of  surfacing  the  most   useful  and  relevant  results.  to  evaluate  relevance  ranking,  subject  specialists  were  asked  to   construct  a  search  query  related  to  their  area  of  expertise,  perform  this  search  in  each  discovery   tool,  and  rate  the  relevancy  of  the  first  ten  results.  results  were  recorded  in  the  exact  order   retrieved  and  ranked  on  a  scale  of  0–3  (0  =  not  relevant,  1  =  somewhat  relevant,  2  =  relevant,  3  =   very  relevant).     two  values  were  used  to  evaluate  the  relevance-­‐ranking  algorithm  of  each  discovery  service.   relevance  was  assessed  by  calculating  cumulative  gain,  or  the  sum  of  all  relevance  scores.  for   example,  if  the  first  ten  results  returned  by  a  discovery  product  received  a  score  of  3  because  they   were  all  deemed  to  be  “very  relevant,”  the  product  would  receive  a  cumulative  gain  score  of  30.   ranking  was  assessed  by  calculating  discounted  cumulative  gain,  which  discounts  the  relevance   score  of  results  on  the  basis  of  where  they  appear  in  the  rankings.  assuming  that  the  relevance  of   results  should  decrease  with  rank,  each  result  after  the  first  was  associated  with  a  discount  factor   of  1/log2i    (where  i  =  rank).  the  relevance  for  each  result  is  multiplied  by  the  discount  factor  to   provide  the  discount  gain.  for  example,  a  result  with  a  relevance  score  of  3  but  a  rank  of  4  is   discounted  through  this  process  to  a  relevance  score  of  1.5.  discounted  cumulative  gain   represents  the  sum  of  all  discount  gain  scores.38   eighteen  librarians  conducted  a  total  of  twenty-­‐six  searches.  using  a  microsoft  excel  worksheet,   participants  were  asked  to  record  their  search  query,  the  titles  of  the  first  ten  results,  and  the   relevance  score  of  each  result  (see  appendix  h).  formulas  for  cumulative  gain  and  discount   cumulative  gain  were  embedded  in  the  worksheet  so  these  values  were  automatically  calculated.   after  all  the  values  were  calculated,  one  product  once  again  had  outperformed  all  others.  in  the     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   34   majority  of  searches  conducted,  librarians  rated  its  results  as  being  more  relevant  than  its   competitors.  however,  librarians  were  quick  to  point  out  that  they  were  not  entirely  satisfied  with   the  results  from  any  of  the  three  products.  in  their  observations,  they  noted  many  of  the  same   issues  that  were  raised  in  previous  rounds  of  testing  such  as  incomplete  metadata,  duplicate   results,  and  overrepresentation  of  certain  types  of  content.     at  the  end  of  the  trial  period,  the  evaluation  team  once  again  invited  feedback  from  the  library   staff.  an  online  library-­‐wide  survey  was  distributed  in  which  staff  members  were  asked  to  rank   each  discovery  product  according  to  several  key  requirements  drawn  from  the  team’s  evaluation   rubric.  each  requirement  was  accompanied  by  one  or  more  questions  for  participants  to  consider   in  their  evaluation.  the  final  question  asked  participants  to  rank  the  three  candidates  in  order  of   preference.  links  to  the  trial  implementations  of  all  three  products  were  included  in  the  survey.   included  in  the  email  announcement  was  also  a  link  to  the  team’s  website  where  participants   could  find  more  information  about  web-­‐scale  discovery.  because  participating  in  the  survey   required  staff  to  review  and  interact  with  all  three  products,  the  team  estimated  that  it  would  take   forty-­‐five  minutes  to  an  hour  to  complete  (depending  on  the  staff  member’s  familiarity  with  the   products).  given  the  amount  of  time  and  effort  required  for  participation,  relevant  committees   were  also  encouraged  to  review  the  trials  and  submit  their  evaluation  as  a  group.  response  rate   for  the  survey  was  much  lower  than  expected,  possibly  because  of  the  amount  of  effort  involved  or   because  a  large  number  of  staff  did  not  feel  qualified  to  comment  on  certain  aspects  of  the   evaluation.  however,  among  the  staff  members  that  did  respond,  one  product  was  rated  more   highly  than  all  others.  coincidentally,  it  was  also  the  same  product  that  had  received  the  highest   scores  in  all  three  rounds  of  testing.   make  final  recommendation   at  this  stage  in  the  process,  your  evaluation  team  should  have  collected  enough  data  to  make  an   informed  selection  decision.  your  decision  should  take  into  consideration  all  of  the  information   gathered  throughout  the  evaluation  process,  including  user  and  product  research,  vendor   demonstrations,  rfp  responses,  customer  references,  staff  and  user  feedback,  trials,  and  product   testing.  in  preparation  for  the  evaluation  team’s  final  meeting,  each  sub  team  was  asked  to  revisit   the  evaluation  rubric.  using  all  of  the  information  that  had  been  collected  and  made  available  on   the  team’s  website,  each  sub  team  was  asked  to  score  the  remaining  three  candidates  based  on   how  well  they  met  the  requirements  in  their  assigned  category  and  submit  a  report  explaining  the   rationale  for  their  scores.  at  the  final  meeting,  a  representative  from  each  sub  team  presented   their  report  to  the  larger  group.  the  entire  team  reviewed  the  scores  awarded  to  each  product.   once  a  consensus  was  reached  on  the  scoring,  the  final  results  were  tabulated  and  the  product   that  received  the  highest  total  score  was  selected.     once  the  evaluation  team  has  reached  a  conclusion,  its  decision  needs  to  be  communicated  to   library  stakeholders.  the  team’s  findings  should  be  compiled  in  a  final  report  that  includes  a  brief   introduction  to  the  subject  of  web-­‐scale  discovery,  the  factors  motivating  the  library’s  decision  to     information  technology  and  libraries  |  june  2015     35   acquire  a  discovery  service,  an  overview  of  the  methods  that  were  used  evaluate  these  services,   and  a  summary  of  the  team’s  final  recommendation.  of  course,  considering  that  few  people  in  your   organization  may  ever  actually  read  the  report,  the  team  should  seek  out  additional  opportunities   to  present  its  findings  to  the  community.  the  rutgers  evaluation  team  presented  its   recommendation  report  on  three  different  occasions.  the  first  was  joint  meeting  of  the  library’s   two  major  governing  councils.  after  securing  the  support  of  the  councils,  the  group’s   recommendation  was  presented  at  a  meeting  of  library  administrators  for  final  approval.  once   approved,  a  third  and  final  presentation  was  given  at  an  all-­‐staff  meeting  and  included  a   demonstration  of  the  selected  product.  by  taking  special  care  to  openly  communicate  the  team’s   decision  and  making  transparent  the  process  used  to  reach  it,  the  evaluation  team  not  only   demonstrated  the  depth  of  its  research  but  also  was  able  to  secure  organizational  buy-­‐in  and   support  for  its  recommendation.   conclusion   selecting  a  web-­‐scale  discovery  service  is  a  large  and  important  undertaking  that  involves  a   significant  investment  of  time,  staff,  and  resources.  finding  the  right  match  begins  with  a  thorough   and  carefully  planned  evaluation  process.  the  evaluation  process  outlined  here  is  intended  as  a   blueprint  that  similar  institutions  may  wish  to  follow.  however,  every  library  has  different  needs,   means,  and  goals.  while  this  process  served  rutgers  well,  certain  elements  may  not  be  applicable   to  your  institution.  regardless  of  what  method  your  library  chooses,  it  should  strive  to  create  an   evaluation  process  that  is  inclusive,  goal-­‐oriented,  data-­‐driven,  user-­‐centered,  and  transparent.   inclusive   web-­‐scale  discovery  impacts  a  wide  variety  of  library  services  and  functions.  therefore  a   complete  and  informed  evaluation  requires  the  participation  and  expertise  of  a  broad  cross   section  of  library  units.  furthermore,  as  with  the  adoption  of  any  new  technology,  the   implementation  of  a  web-­‐scale  discovery  service  can  be  potentially  disruptive.  these  products   introduce  significant  and  sometimes  controversial  changes  to  staff  workflows,  user  behavior,  and   library  usage.  ensuring  broad  involvement  in  the  evaluation  process  can  help  allay  potential   concerns,  reduce  tensions,  and  ensure  wider  adoption.   goal-­‐oriented     it  can  be  easy  to  be  seduced  by  new  technologies  simply  because  they  are  new.  but  merely   adopting  these  technologies  without  taking  to  the  time  to  reflect  on  and  communicate  their   purpose  and  goals  can  be  a  recipe  for  disaster.  to  select  the  best  discovery  tool  for  your  library,   evaluators  must  have  a  clear  understanding  of  the  problems  it  is  trying  to  solve,  the  audience  it   seeks  to  serve,  and  the  role  it  plays  within  the  library’s  larger  mission.  articulating  the  library’s   vision  and  goals  for  web-­‐scale  discovery  is  crucial  for  establishing  an  evaluation  plan,  developing  a   prioritized  list  of  product  requirements,  understanding  what  questions  to  ask  vendors,  and  setting   benchmarks  by  which  to  evaluate  performance.     evaluating  web-­‐scale  discovery  services:  a  step-­‐by-­‐step  guide  |  deodato   doi:  10.6017/ital.v34i2.5745   36   data-­‐driven   to  ensure  an  informed,  fair,  and  impartial  evaluation,  evaluators  should  strive  to  incorporate   data-­‐driven  practices  into  all  of  their  decision-­‐making.  many  library  stakeholders,  including   members  of  the  evaluation  team,  may  enter  the  evaluation  process  with  preexisting  views  on  web-­‐ scale  discovery,  untested  assumptions  about  user  behavior,  or  strong  opinions  about  specific   products  and  vendors.  to  minimize  the  influence  of  these  potential  biases  on  the  selection  process,   it  is  important  that  the  team  be  able  to  demonstrate  the  rationale  for  its  decisions  through   verifiable  data.  evaluating  web-­‐scale  discovery  services  requires  extensive  research  and  should   include  data  collected  through  user  research,  staff  surveys,  collections  analysis,  and  product   testing.  all  of  this  data  should  be  carefully  collected,  analyzed,  and  used  to  inform  the  team’s  final   recommendation.     user-­‐centered   if  the  purpose  of  adopting  a  web-­‐scale  discovery  service  is  to  better  serve  your  users,  then  you   should  try  as  much  as  possible  to  involve  users  in  the  evaluation  and  selection  process.  this   means  including  users  on  the  evaluation  team,  grounding  product  requirements  in  user  research,   and  gathering  user  feedback  through  surveys,  focus  groups,  and  product  testing.  this  last  step  is   especially  important.  no  other  piece  of  information  gathered  throughout  the  evaluation  process   will  be  as  helpful  or  revealing  as  actually  watching  users  use  these  products  to  complete  real-­‐life   research  tasks.  user  testing  is  the  best  and,  frankly,  only  way  to  validate  claims  from  both  vendors   and  librarians  about  what  your  users  want  and  need  from  your  library’s  search  environment.     transparent   because  web-­‐scale  discovery  impacts  library  staff  and  users  in  significant  ways,  its  reception   within  academic  libraries  has  been  somewhat  mixed.  as  previously  mentioned,  securing  staff  buy-­‐ in  is  often  one  of  the  most  difficult  obstacles  libraries  face  when  introducing  a  new  web-­‐scale   discovery  service.  while  encouraging  broad  participation  in  the  evaluation  process  helps  facilitate   buy-­‐in,  not  every  library  stakeholder  will  be  able  to  participate.  therefore  it  is  important  that  the   evaluation  team  make  special  effort  to  communicate  its  work  and  keep  the  library  community   updated  on  its  progress.  this  can  be  done  by  creating  a  staff  website  or  blog  devoted  to  the   evaluation  process,  sending  periodic  updates  via  the  library’s  electronic  discussion  list,  holding   public  forums  and  demonstrations,  regularly  soliciting  staff  feedback  through  surveys  and  polls,   and  widely  distributing  the  team’s  findings  and  final  report.  these  communications  should  help   secure  organizational  support  by  making  clear  that  the  team  recommendations  are  based  on  a   thorough  evaluation  that  is  inclusive,  goal-­‐oriented,  data-­‐driven,  user-­‐centered,  and  transparent.         information  technology  and  libraries  |  june  2015     37   appendix  a.  overview

2005 s o, three plus years after the fact, why am i opening with michael gorman’s unfortunate characterization of those he labeled “blog people”? i have no interest in reopening this debate, honestly! but the problem with generalizations, however unfair, is that at their heart there is just enough substance to make them “stick”—to give them a grain or two of credibility. gorman’s words struck a chord in me that existed before his charge and has continued to exist to this day. the substance in gorman’s words had little to do with these “blog people” as such; rather, my interest was piqued by the implications in his remark about how we all deal with “complex texts” and the “sustained reading” of the same. in a time of wide availability of full-text electronic articles, it has become so easy and tempting to cherry pick the odd phrase here or there, without study of the work as a whole. how has scholarship especially been changed by the ease with which we can reduce works to snippets without having considered their overall context? i’m not arguing that scholarly research and writing hasn’t always been at least in part about finding the perfect juicy quotation around which we then weave our own theses. many of us well recall the boxes of 3x5” citation and 5x8” quotation files that we or our patrons laboriously assembled through weeks, months, and years of detailed research. but if the style of compiling these files that i witnessed (and indeed did) is any guide, their existence was the product of precisely that “sustained reading of complex texts” of which gorman spoke. my vague, nagging sense is that what is changing is this style of approaching whole texts. i wondered then about how much scholarly research today is driven by keyword searches of digitized texts that then essentially produce “virtual quotation files” without our having had to struggle with their context in the whole of the original source text? fast forward three years. lately, several articles touching on our changing ways of interacting with resources have appeared in both scholarly and popular venues, and these have served to underline my sense that we are missing something because of our growing lack of engagement with whole texts. writing in the july/august issue of the atlantic monthly, nicholas carr asks “is google making us stupid?” drawing an analogy to the scene in the film 2001: a space odyssey, in which astronaut dave bowman disables supercomputer hal’s memory circuits, carr says i can feel it, too. over the past few years i’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. my mind isn’t going—so far as i can tell—but it’s changing. i’m not thinking the way i used to think. i can feel it most strongly when i’m reading. immersing myself in a book or a lengthy article used to be easy. my mind would get caught up in the narrative or the turns of the argument, and i’d spend hours strolling through long stretches of prose. that’s rarely the case anymore. now my concentration often starts to drift after two or three pages. i get fidgety, lose the thread, begin looking for something else to do. i feel as if i’m always dragging my wayward brain back to the text. the deep reading that used to come naturally has become a struggle.1 carr goes on to explain that “what the net seems to be doing is chipping away my capacity for concentration and contemplation. my mind now expects to take in information the way the net distributes it: in a swiftly moving stream of particles. once i was a scuba diver in the sea of words. now i zip along the surface like a guy on a jet ski.”2 carr’s nagging fear found similar expression among some tech-savvy participants of library online forums; one of the more interesting comments appeared on the web4lib electronic discussion list. in a discussion of the article, tim spalding of librarything observed that he himself had experienced what he dubbed “the google effect” and noted something is lost. . . . human culture often advances by externalizing pieces of our mental life—writing externalizes memory, calculators externalize arithmetic, maps, and now gps, externalize way-finding, etc. each shift changes the culture. and each shift comes with a cost. nobody memorizes texts anymore, nobody knows the times tables past ten or twelve and nobody can find their way home from the stars and the side of the tree the moss grows on.3 meanwhile, another article appeared on a closely related topic, this time in the journal science. james a. evans observed that, because “scientists and scholars tend to search electronically and follow hyperlinks rather than browse or peruse,” the easy availability of electronic resources was resulting in an “ironic change” for scientific marc truitt (marc.truitt@ualberta.ca) is associate director, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 4 information technology and libraries | september 2008 scholarship, in that as more journal issues came online, the articles referenced tended to be more recent, fewer journals and articles were cited, and more of those citations were to fewer journals and articles. the forced browsing of print archives may have stretched scientists and scholars to anchor findings deeply into past and present scholarship. searching online is more efficient and following hyperlinks quickly puts researchers in touch with prevailing opinion, but this may accelerate consensus and narrow the range of findings and ideas built upon.4 evans’s research highlights an additional irony: an unintended benefit to the scholarly process in the paperbased world was “poor indexing,” since it encouraged browsing through less relevant, older, or more marginal literature. this browsing had the effect of “facilitat[ing] broader comparisons and led researchers into the past. modern graduate education parallels this shift in publication—shorter in years, more specialized in scope, culminating less frequently in a true dissertation than an album of articles.”5 what is one to make of all of this? at the outset, i wish to state clearly that i am not some sort of anti e-text luddite. electronic texts are a fact of life, and are becoming moreso every day. even though they are in their infancy as a medium, they’ve already transformed the landscape of bibliographic access. my interest is not with the tool, but with the manner in which we are using it. i began by suggesting that i share with gorman a concern about how we increasingly engage with “complex texts” today. unlike him, though, my concern is not limited only to the so-called blog people (whomever they may be), but indeed, it includes all of us. with the explosion in easily accessible electronic texts, our ideas and habits concerning interaction with these texts are changing, sometimes in unintended ways. in a recent informal survey i conducted of my colleagues at work, i asked, “have you ever read an e-book (not just a journal article) from (virtual) cover to (virtual) cover?” for those whose answer was affirmative, i also asked, “how many such books have you read in their entirety?” out of twenty-odd responses, three individuals answered that yes, they had had occasion to read an entire e-book (for a total of six books among the three “yes” respondents, which seemed surprisingly high to me). of greater interest, though, were those who chose to question the premise of the survey, arguing that people don’t “read” e-books the way that they read paper ones. it does make one wonder, then, how amazon thinks it possesses a viable business model in the kindle e-book reader, for which it currently lists an astounding 140,000+ available e-books. clearly, some e-books are being read as whole texts, by some people, for some purposes. but i suspect that’s another story.6 carr and evans use slightly differing imagery to describe a similar phenomenon. carr closes with a reference back to the death of 2001’s hal, saying, “as we come to rely on computers to mediate our understanding of the world, it is our own intelligence that flattens into artificial intelligence.”7 evans, on the other hand, compares contemporary scientific researchers to newton and darwin, each of whom produced works that “not only were engaged in current debates, but wove their propositions into conversation with astronomers, geometers, and naturalists from centuries past.” twenty-first-century scientists and scholars, by contrast, are able because of readily available electronic resources “to frame and publish their arguments more efficiently, [but] they weave them into a more focused—and more narrow—past and present.” 8 perhaps the most succinct statement, though, comes from librarything’s tim spalding, who summarized the problem thusly: “we advance by becoming dumber.”9 an ital research and publishing opportunity for an inquisitive and enterprising scholar, perhaps? i’d welcome the manuscript! shameless plugs department. by the time you read this, we at ital will have launched our new blog, italica (http://ital-ica.blogspot.com). italica addresses a need we on the ital editorial board have long sensed; that is, an area for “letters to the editor,” updates to articles, supplementary materials we can’t work into the journal—you name it. one of the most important features of italica will be a forum for readers’ conversations with our authors: we’ll ask authors to host and monitor discussion for a period of time after publication so that you’ll then have a chance to interact with them. italica is currently a pilot project. for our first issue we will have begun with a discussion hosted by jennifer bowen, whose article “metadata to support next-generation library resource discovery: lessons from the extensible catalog, phase i” was published in the june 2008 issue of ital. for our second italica, we plan to expand coverage and discussion to include all articles and other features in the september issue you now have in hand. italica is sure to become a stimulating supplement to and forum for topics originating in ital. we look forward to seeing you there! references and notes extract. michael gorman, “revenge of the blog

frisquepresident’s message i know the president’s message is usually dedicated to talking about where lita is now or where we are hoping lita will be in the future, but i would like to deviate from the usual path. the theme of this issue of ital is “discovery,” and i thought i would participate in that theme. like all of you, i wear many hats. i am president of lita. i am head of the information services department at the galter health sciences library at northwestern university. i also am a new part-time student in the masters of learning and organizational change program at northwestern university. as a student and a practicing librarian, i am now on both sides of the discovery process. as head of the information systems department, i lead the team that is responsible for developing and maintaining a website that assists our health-care clinicians, researchers, students, and staff with selecting and managing the electronic information they need when they need it. as a student, i am a user of a library discovery system. in a recent class, we were learning about the burkelitwin causal model of organization performance and change. the article we were reading described the model; however, it did not answer all of my questions. i thought about my options and decided i should investigate further. before i continue, i should confess that, like many students, i was working on this homework assignment at the last minute, so the resources had to be available online. this should be easy, right? i wanted to find an overview of the model. i first tried the library’s website using several search strategies and browsed the resources in metalib, the library catalog, and libguides with no luck. the information i found was not what i was looking for. i then tried wikipedia without success. finally, as a last resort, i searched google. i figured i would find something there, right? i didn’t. while i found many scholarly articles and sites that would give me more information for a fee, none of the results i reviewed gave me an overview of the model in question. i gave up. the student in me thought: it should not be this hard! the librarian in me just wanted to forget i had ever had this experience. this got me to thinking: why is this so hard? libraries have “stuff” everywhere. we access “stuff,” like books, journals, articles, images, datasets, etc., from hundreds of vendors and thousands of publishers who guard their stuff and dictate how we and our users can access that stuff. that’s a problem. i could come up with a million other reasons why this is so difficult, but i won’t. instead, i would like to think about what could be. in this same class we learned about appreciative inquiry (ai) theory. i am simplifying the theory, but the essence of ai is to think about what you want something to be instead of identifying the problems of what is. i decided to put ai to the test and tried to come up with my ideal discovery process. i put both my student and librarian hats on, and here is what i have come up with so far: n i want to enter my search in one place and search once for what i need. i don’t want to have to search the same terms many times in various locations in the hopes one of them has what i am looking for. i don’t care where the stuff is or who provides the information. if i am allowed to access it i want to search it. n i want items to be recommended to me on the basis of what i am searching. i also want the system to recommend other searches i might want to try. n i want the search results to be organized for me. while perusing a result list can be loads of fun because you never know what you might find, i don’t always have time to go through pages and pages of information. n i want the search results to be returned to me in a timely manner. n i want the system to learn from me and others so that the results list improves over time. n i want to find the answer. i’m sure if i had time i would come up with more. while we aren’t there yet, we should continually take steps—both big and small—to perfect the discovery process. i look forward to reading the articles in this issue to see what other librarians have discovered, and i hope to learn new things that will bring us one step closer to creating the ultimate discovery experience. michelle frisque (mfrisque@northwestern.edu) is lita president 2009–10 and

the time of cholera abstract in november 2019, binghamton university libraries initiated a website redesign project. our goal was to create a user-centered, data-informed website with refreshed content and upgraded functionality. originally, our redesign plan included in-person card-sorting activities, focus groups, and usability studies, but when the libraries went remote in march 2020 due to the covid-19 pandemic, we had to quickly reassess and adapt our processes and workflows. in this article, we will discuss how we completed this significant project remotely by relying on effective project management, communication, teamwork, and flexibility. introduction website redesign projects can be daunting, even during normal circumstances. this article will outline how we accomplished a website redesign project in a reasonable timeframe during the unprecedented circumstances of the covid-19 pandemic. binghamton university is part of the state university of new york (suny) system. founded in 1946, it has an enrollment of about 18,000 graduate and undergraduate students. binghamton university libraries are an important part of the university, serving as the center of the university’s intellectual community. our website is the libraries’ most important tool for “scaling up” services to our users. it is as important as the physical library and became even more so with the digital demands imposed by covid, particularly the importance of access to streaming video during the pandemic. a truism in website redesign is that your current website is never more popular than when you take it down. however, our redesigned website was successfully launched to general approbation and is considered a functional and cosmetic improvement over the old website. we were pleasantly surprised how little negative feedback we received. people just started using it, which may be the highest compliment paid to a design team. as we will highlight throughout the article, we believe that the success of this project was the result of the following: • a dedicated/functional web team, • the ability to meet frequently and on a moment’s notice, • the ability to focus almost exclusively on the project; and • effective project management. mailto:erushton@binghamton.edu_ mailto:mulligan@binghamton.edu information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 2 premise for the redesign the last time the libraries had fully redesigned the website was in 2013. that project was significant because we had migrated from a locally hosted site to the university’s web content management system, omniupdate. highlights of the 2013 redesign included a fresh look and feel with binghamton university colors, updated site architecture and navigation, and expanded search options from the home page. up until 2013, we had typically redesigned our website on a five-year cycle. as such, we began discussing the possibility of another redesign in mid-2018. we also thought it was an opportune time to redesign the website because the libraries had a new dean, we were offering new services and initiatives, and we had become more mindful of accessibility issues and responsive design. the web team the libraries’ web team is the group that leads website redesign projects and maintains the website. the team generally meets as needed between redesign projects. in anticipation of the planned 2019–2020 redesign, however, we began scheduling more regular meetings. our preferred meeting times were friday mornings. one of the prerequisites for these meetings was to take turns bringing bagels and juice. we quickly got to know what kind of bagel each of us preferred. in november 2019, the team consisted of ben coury, bern mulligan, erin rushton (chair), and dave vose. except for ben, the other members of the web team had participated in several past library website redesigns. ben had recently been hired as the libraries’ digital web designer. he brought high-end programming skills to the team and expertise and knowledge about user experience and accessibility which were integral to the success of the project. it was an advantage to have a small, dedicated, and agile team that collaborated and communicated well. this positive chemistry or esprit de corps among members allowed us to debate any controversial issues professionally, not personally. we internalized the team’s mission and worked single-mindedly toward its successful completion. binghamton university is a google campus, which meant we had access to the full suite of google apps (e.g., gmail, google calendar, google drive, google groups, etc.). at the beginning of the redesign, we had already begun to use google to create, share, and archive our committee documents. project timeline this is the timeline for the project, which took ten months to complete. it occurred basically in two phases: before covid and after covid. much of the work that occurred before covid was completed in person. all of what occurred after covid was done virtually: via email, phone, and, as was the case with most organizations during the pandemic, via zoom. • november 2019: planning phase • december 2019–march 11, 2020: in-person meetings with library constituent groups • march 12, 2020: meeting with student advisory group • march 17,

19, 2020: successful launch of the new website when planning a website redesign project, it is understood that there will be a lot of meetings. as the pace of the project accelerates and as the deadline approaches, so does the frequency of meetings. during the ten months of this project, we met 64 times: 16 in-person meetings from november 2012 to march 12, 2020; 25 virtual meetings from march 17 to the end of june; and 23 virtual meetings in july and august. during july and august until launch, the other aspects of our jobs took a back seat to the proj ect; it’s pretty much all we worked on. we sometimes met twice a day, and that’s not counting the incidental phone calls between individual members for questions about sticking points in the process. november 2019: planning phase the libraries’ user interface steering committee (uisc) has oversight for the various public library interfaces, including the website. the committee consists of the web team members and representatives from different departments in the libraries, including public services, technic al services, and special collections. the uisc helped us establish the goals and objectives for the redesign project, gave us feedback about ideas during the redesign process, and monitored our ongoing progress. there were four goals that became apparent almost immediately. over the years, many website development requests had been postponed, so our first goal was to accommodate these improvements and enhancements. and since university communications and marketing, the unit on campus responsible for the entire university web domain, had updated templates since our last redesign, our second goal was to utilize the new templates. our third goal was to create a usercentered, data-informed website. finally, our fourth goal was to address accessibility issues on the website and make it easier for users to navigate. december 2019–march 11, 2020: in-person meetings with library constituent groups once the goals had been established, we began scheduling meetings with a variety of library constituent groups. these included preservation, reader services, special collections, and dean’s council. it was important for us to get input from these groups because we wanted everyone to feel represented by the project since the website is the gateway for many of our services and resources. we also wanted the redesign process to be transparent so that everyone knew what was happening. at each meeting, we discussed how the website was working for their area and what improvements they wanted to see. we also provided a snapshot of the website for each area which showed current usage statistics (see fig. 1). information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 4 figure 1. screenshot of a website inventory spreadsheet for special collections. march 12, 2020: meeting with student advisory group we met with the student library advisory committee (slac) on march 12. this group offered open, two-way communication between the libraries and the student population and provided a mechanism for the libraries to solicit feedback on specific issues as needed. as an incentive for students attending this meeting, we provided free pizza and snacks. at this meeting, we asked the students a variety of questions, including why they used the website and what they liked and disliked about it. some of the answers we received were surprising to us. for one thing, few of the students began their research from our website. while they had used the website, they were not particularly familiar with most of its features. a second consensus of the group was that if they wanted to know something about the libraries (e.g., our hours), they just googled it. finally, although our ask a librarian service was linked from several places on the website, none of the students in the group had ever noticed it and were unaware of the service. these revelations further informed what we wanted to address in the redesign. march 17, 2020: covid shutdown on march 17, the university abruptly closed in-person services due to the growing pandemic. for a few weeks after the shutdown, the priority for all university employees was transitioning to remote work and providing virtual services. once we felt ready to resume the project, we had to reassess how we would continue it remotely. there were two significant challenges: how to continue our committee work as a distributed team and how to continue gathering user feedback given that no one was physically on campus. we discovered that transitioning into a distributed team worked well for the project. we no longer had to reserve meeting spaces and set up laptops and projectors. instead, we could quickly organize zoom meetings, sometimes on the fly, when we had something we wanted to discuss. and all our committee files were already on google drive. as a result, we were better able to focus almost exclusively on the project and were less impacted by the distractions that often occur in the office environment. information

or the “guerrilla” usability testing with students that we had planned. however, we were glad to have had the in-person meetings with some of our constituents before the work-from-home phase because we had established a good foundation of what we needed to accomplish in the redesign. april 15, 2020: meeting with communications and marketing one of the first groups we met with virtually was university communications and marketing (c&m). as mentioned above, this is the unit on campus that is responsible for omniupdate, the university’s website platform. the purpose of this meeting was to discuss our plans and timeline and to clarify the role of c&m in the project. although we now had our own web designer in ben, we knew that c&m had oversight over the entire university web presence and would have to decide whether our redesign fit in with the rest of the domain in terms of its appearance and accessibility. april-june 2020: website architecture and content review the next significant part of the project was reviewing our current pages. during preliminary planning the year before, we had a student list all pages of the libraries’ website in a google spreadsheet which also included google analytics from the three previous years. we literally spent hours poring over this document (see fig. 2). it helped us identify which pages would migrate mostly as is, which pages would need additional review, which pages would be converted to libguides and vice versa, and which pages would be deleted. figure 2. screenshot of a spreadsheet listing all library web pages. information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 6 originally, we had planned to do a physical card sorting like we had done in past redesigns. we had even created the cards and had scheduled an all-day card-sorting event, complete with pizza. but covid changed all that. since we were meeting virtually, we had to think of another way to accomplish this. a breakthrough occurred when ben introduced trello, an online collaboration and project management tool that allowed us to work together on the new website’s architecture in real time via zoom (see fig. 3). figure 3. screenshot of a trello board. we recreated the six existing main navigation categories and created “cards” for each web page. trello made it easy to move these virtual cards around into the different categories. we had received feedback that six categories were perhaps too many for users to choose from. we spent a number of meetings in may discussing/debating what the new navigation categories should be and where pages fit under them. we decided to fold the locations & collections and special collections sections into about, and search & find into research, because we felt these changes made more logical and functional sense. we added a top-level link to my account because this was also something that users had suggested should be more prominent. another aspect of the libraries’ website redesign project was the content of libguides. initially, they were meant to be subject guides, but over the years some of our web pages were converted into libguides. as part of the redesign, we worked closely with the collections and instruction department to make decisions about where content should be located. most libguides are now subject or research guides while descriptions of libraries’ services are web pages. july 2020: creating templates, migrating content, and designing the home page by the end of june, we had accomplished the following: • met with available constituencies, • identified what content we needed to migrate, • identified what content needed to be created; and • had a new website architecture. information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 7 at this point, we felt we needed to focus on the actual migration of content and the design of the home page. on july 2, we met virtually with collections and instruction to discuss how the search box on the home page would look and function. it was no mean feat coming to consensus on this. we were on a tight schedule, but we wanted to be sure that we heard everyone’s ideas. taking all feedback into consideration, ben then had the ultimate challenge of coding and designing a functioning search box. for the last three weeks of july, we met daily, and sometimes twice a day, as we began the daunting process of migrating all the lower-level pages. we were definitely feeling the pressure to complete the project on time. since we were using the new university templates, designing the lower-level pages was relatively straightforward. ben had customized the template and provided us with a migration guide. the guide included instructions on how to create and format new pages. this allowed the other members of the web team to migrate content while he focused on the more complicated aspects of the project. all migrated content was reviewed to ensure that it was current. for some pages, this required input from several departments. to facilitate the updating, we copied the content of every page we were migrating into a google doc to allow for collaborative editing. once the content was updated, it would be copied and pasted into the new template. the screenshot in figure 4 represents the redesign for most of the lower-level pages. figure 4. screenshot of a new lower-level page. information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 8 the most significant changes were the relocation of the navigation column from left to right and some new features that were included in omniupdate, including the ability to add contact information. we had to do some formatting, such as adding headings and hyperlinks, and some metadata work, such as creating page descriptions and keywords. we also had to pick a photo for the banner of each page. we had planned to have the university photographer take new photos, but because there were no students and hardly any staff on campus, we had to rely on pictures of our spaces he had already taken. we were tracking the migration on a spreadsheet (see fig. 5). this document contained the new architecture of the website and had links to the google docs mentioned previously. the spreadsheet also noted who was responsible for reviewing the content and the status of each page. figure 5. screenshot of the spreadsheet used to track the migration of webpages. while this mass migration was taking place, ben focused on creating the pages that required additional coding and customization such as the ask a librarian page, the staff directory, and library tutorials. he also worked on the design of the home page. one of the tools ben used to help with the mock-up was adobe xd (see fig. 6). information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 9 figure 6. screenshot of initial design of home page in adobe xd. adobe xd is a design tool in the adobe suite used for prototyping user interfaces. he created an interactive wireframe for the home page and landing pages. this allowed us to discuss the interface and make changes without a lot of time spent on mock-ups. information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 10 august 2020: final meetings and details we met with the user interface steering committee on august 5 to get their input on the redesign. on august 7, we met with communications and marketing again to go over our design and get final approval for our home page. we also previewed the site to library people at an all-staff meeting later that day. the final week before site launch was dedicated to the special collections pages that had embedded links for finding aids and to working on the ask a librarian page. and the last day was spent going through and making sure everything was in order before launch. august 19, 2020: successful launch of the new website we launched the redesigned website on august 19 (see fig. 7). some of its new features include • a large “hero” photo which can easily be changed depending on what the libraries want to promote; • a redesigned search box; • popular links featured on the home page; • a news section which pulls from our blog software and allows for automatic updates; and • a prominent, visually attractive place on the home page for special collections since it was bumped from the top navigation bar. figure 7. partial screenshot of the new library home page. information technology and libraries december 2022 a library website redesign in the time of covid | rushton and mulligan 11 conclusion the process that we had initially envisioned did not work out because of the covid-19 pandemic. although we did meet with our student advisory group, we never got to hold any focus groups with teaching faculty or usability studies with students. but thanks to zoom and other online tools, we were still able to gather some user feedback. we also had a new website ready before fall 2020. while there was certainly unanticipated stress in tackling a project like this in the middle of a pandemic, we felt that working remotely in some ways helped us to be more productive. we were better able to focus almost exclusively on this project and were less impacted by the distractions that often occur in the office environment. we also felt that the quick adoption of zoom made us more agile about scheduling and holding meetings. despite some of the challenges that we faced throughout the project, the redesigned website is a success. since the launch, we have made a few minor changes to the overall architecture of the site. the most significant change was adding a giving link to the navigation menu at the req uest of our dean and the binghamton university foundation. our library website is never static, as we continue to update our home page with news and events and change our hero banner to reflect the priorities of the libraries. while we have no plans for another major redesign in the near future, we are open to making changes and improvements as needed.

materials related to japanese military “comfort women” in korea are managed by several institutions. each digital archive has their own metadata schema and management policies. so far, a standard or a common guideline for describing digital records is not formalized. we propose a japanese military “comfort women” knowledge graph to semantically interlink the digital records from distributed digital archives. to build a japanese military “comfort women” knowledge graph, digital records and descriptive metadata were collected from existing digital archives. a list of metadata was defined by analyzing commonly used properties and a knowledge model designed by reusing standard vocabularies. knowledge was constructed by interlinking the collected records, external data sources, and enriching data. the knowledge graph was evaluated using the fair data maturity model. introduction in december 1991, kim hak-sun (a korean) became the first woman to disclose and identify as a former “comfort woman.”1 in february 1992, ms. itoh hideko discovered three telegrams in the japanese defense agency stating that not only korean but also taiwanese women had been dispatched as “comfort women.”2 between 1931 and 1945, the imperial japanese army forced approximately 200,000 girls and young women from korea, china, and other countries, known as “comfort women,” into sexual slavery. these women came from all over east asia, but the majority, over 80 percent, were from south korea.3 it was not until the early 1990s that survivors began to share their stories and demand justice. many international organizations and volunteers continue to participate in advocacy and campaigns to solve the japanese military sexual slavery.4 however, the japanese government has never accepted legal responsibility or agreed to pay reparations.5 regardless of political interpretation, we believe it is critical to reveal the historical truth. the records of japanese military “comfort women” serve as objective evidence to prove the fact that the japanese military indulged in sexual slavery. as there are now only 13 elderly survivors left in south korea, the records could serve as one of the key pieces of evidence for understanding the japanese military “comfort women.” in korea, materials related to japanese military “comfort women” are managed by the national archives of korea and some private organizations, and some of this material is being provided as digital archives.6 digital archives systematically describe digital resources so that users can effectively search and view the materials.7 in general, digital archives describe digital resources based on guidelines for expressing standard metadata elements and data values that are mainly used in the domain. for mailto:haram9553@gmail.com mailto:haklaekim@cau.ac.kr information technology and libraries march 2023 japanese military “comfort women” knowledge graph 2 park and kim example, the us library of congress is creating digital resources with varying levels and types of descriptive metadata, providing an increasingly coordinated and standardized approach to the creation and management of descriptive metadata.8 however, for the digital archives related to japanese military “comfort women,” there are no recommendations or agreed guidelines on metadata for describing digital records. even when metadata standards such as dublin core are used, there remain variations in describing metadata elements of digital records. therefore, linking or integrating the digital records with different metadata structures and values is difficult. to solve this problem, a metadata model to describe digital records related to japanese military “comfort women” should be developed, and digital records should be systematically described. if the various pieces of information contained in the digital record are expressed in a format that a machine can understand, a precise search is possible based on the meaning and relationship of the data. a knowledge graph can be applied to define the relationships between the various entities included in japanese military “comfort women” records. in particular, the records existing in a distributed digital archive can be expressed as objects that can be identified on the web, so that different records can be linked at a semantic level.9 this study proposes a method to interlink and search digital records of the digital archives of japanese military “comfort women.” for describing and linking distributed digital records, a set of metadata elements was proposed, and a knowledge model was defined by examining the common metadata model and the existing rdf vocabulary. the collected digital records were constructed as a knowledge graph, using a knowledge model. the knowledge graph was evaluated by applying the fair data maturity model.10 the remainder of this paper is organized as follows. the literature review introduces the japanese military “comfort women” issue and describes the concepts and research trends related to knowledge graphs. we then introduce the case of korean digital archives containing materials about the japanese military’s use of “comfort women.” next, we describe the process of developing a knowledge graph in detail and define sparql queries, comparing the search results of existing digital archives and knowledge graphs, and describing differences in fair data maturity. finally, the research results are summarized, and future research directions are described. literature review japanese military “comfort women” the japanese military “comfort women” issue was made official in 1991 when the korean council for the women drafted for military sexual slavery by japan and the korean victims appealed to solve the problem themselves,11 through activities such as the testimony of victims,12 and the activities of individual researchers and civic groups,13 raising issues through the international community and through domestic and international judicial procedures.14 through these efforts, the japanese military “comfort women” issue has been seen as a problem of forced mobilization, human trafficking, sexual exploitation, and extreme human rights violations by the ruling state targeting women in the colonized state.15 however, the japanese military “comfort women” were a cause of conflict and confrontation between victims and their families, private organizations, and the south korean and japanese governments. for example, mark ramseyer defined the japanese military “comfort women” in his paper as prostitutes (ianfu) who, based on game theory, engaged in prostitution to the japanese military for high wages during the pacific war.16 this sparked a information technology and libraries march 2023 japanese military “comfort women” knowledge graph 3 park and kim debate about historical distortion.17 some argue that the “comfort women” issue is not viewed as a conflict between korea and japan but as a women’s and a universal human rights issue.18 from a political and social point of view, research on the japanese military “comfort women” is active, but insufficient research has been conducted on archives and records management due to licensing of records, data sharing, and a lack of qualified personnel. various licensing policies and sharing limitations apply to the records kept by different institutions. as a result, the preservation and exchange of documents are nominal, and they are administered with a minimal amount of personnel. records are essential evidence for discussing historical truths. fifteen organizations, from eight countries, have tried to list the records of the japanese military “comfort women” as unesco world’s documentary heritage.19 a total of 2,744 records have been requested, including materials that prove the japanese military’s “comfort women” system or materials produced by “comfort women” victims. however, the decision to list japanese military “comfort women” records as unesco documentary heritage has been postponed due to tensions between south korea and japan.20 the national archives of korea has selected materials related to the “comfort women” of the japanese military as a nation-designated record and is integrating and managing these records.21 however, most records are scattered in various university research institutes, nongovernmental organizations, and institutions, and it is difficult to systematically preserve and manage them. reuse of ontology vocabularies and fair data principles the records of the japanese military “comfort women” are not systematically managed, and existing digital archives tend not to contain sufficient information contained in the original records. a previous study suggested a metadata schema for the integrated management of the records of japanese military “comfort women.”22 however, although most studies suggest common metadata elements, they do not include methods for representing and processing records in a machine-readable format.23 reusing vocabularies is recommended to foster interoperability and facilitate knowledge use by interlinking new datasets to existing resources. some previous efforts demonstrate a way of interlinking digital resources on the web by using several ontology vocabularies.24 in particular, freire et al. propose a mapping from schema.org metadata to the europeana data model. the proposed method is suitable for metadata aggregation in the area of cultural heritage by enriching the semantics of the schema.org model.25 the fair data principles are designed to reinforce the reusability of research data and are defined as four principles: findable, accessible, interoperable, and reusable.26 in particular, the fair principles emphasize the ability of machines to find and use data on their own, in accordance with the research data management environment.27 initially, the fair principles were recognized as a tool to enhance the reusability of research data in the context of open science; however, they are now being extended to a universal framework for preserving and managing data in the long term.28 representative examples include fair metrics,29 the data maturity model of the rda (research data alliance) working group,30 and fairsfair.31 fair metrics presents an evaluation framework that can measure fair indices using an automated tool. discussions on the fair principle are also expanding in digital archives and libraries.32 koster and woutersen-windhouwer propose the fair principle suitable for lam (libraries, archives, museums) collections and suggest a practical method to increase the reusability of digital cultural heritage.33 information technology and libraries march 2023 japanese military “comfort women” knowledge graph 4 park and kim digital archives of japanese military “comfort women” the records or documents of the japanese military “comfort women” are managed in the form of digital archives by national and private institutions. table 1 summarizes the status of digital archives held by each institution as representative digital archives. the wednesday demonstration archive is a digital archive operated by the korean council. it contains a record of the “regular demand demonstration to solve the japanese military’s sexual slavery problem” that began in january 1992. the archive contains 1,085 records, and each record is described with 17 metadata elements. archive 814, named for the annual day of remembrance of the japanese military “comfort women” observed on august 14, aims to develop efforts and research results table 1. status of records by archives archives organization number of digital records number of descriptive metadata url

legal records, official documents, collections by subject, chronological tables, and book lists. the seoul archives provides documents proving the existence of japanese military “comfort women” and comfort stations from documents produced by the allied forces during world war ii. in total, 137 records were provided, and each record consisted of 25 descriptive metadata elements. the gender archive provides documents on the issue of “military sexual slavery by japan” and “the women’s international war crimes tribunal on japan’s military sexual slavery.” a total of 408 records were provided, with 88 metadata elements describing each record. the national archives of korea has designated records related to japanese military “comfort women” as nation-designated archives no. 8. among the records (approximately 3,060 cases) owned by house of sharing (http://www.nanum.org/eng/main/index.php) and daegu citizen forum for halmuni (http://www.1945815.or.kr/), 27 records are selected as major records, and digitized records including 20 metadata elements are provided. development of japanese military “comfort women” knowledge graph data preprocessing a total of 2,253 records and metadata were collected from the five digital archives. excluding records with insufficient information (a814 and nak had three and two documents, respectively), 2,248 records were constructed as a knowledge graph. metadata values in the collected records are not consistently expressed. for example, the seoul archives indicates the institution in the form “[organization/group] jinseong jeong research team, seoul national university, 2015,” whereas “kunji takei, governor of yamagata prefecture” in archive 814 has a combination of person, organization, and his position together. these values are separated into relevant categories and described in the corresponding metadata elements (e.g., “kunji takei, governor of yamagata prefecture” is divided to “kunji takei” (name) and “yamagata prefecture” (his position)). the units for expressing metadata values such as “production date” and “language” are also unified, and errors in some data values are corrected directly (e.g., “gabrelle kirk mcdonald” is changed to “gabrielle kirk mcdonald”, restoring the “i” to her first name). in addition, a new classification system is defined by aligning and integrating existing categories, since digital archives uses different categories (e.g., book/publication, document). a model of designing a knowledge graph two tasks are performed to transform the collected data into a knowledge graph. since the metadata elements used in digital archives are different, metadata properties commonly used in archives are extracted. for common metadata, the scope of reuse is determined by investigating the existing rdf vocabularies and adding to the proposed knowledge model. common metadata elements among the selected archives are defined by the following two criteria: 1. metadata elements commonly used in all archives were extracted. metadata elements present in all five archives, such as title, description, identifier, license, and url are mandatory. metadata elements defined in two or more archives, such as “production date” and “language,” are optional properties. even if the metadata name written in korean is different, it is regarded as the same metadata element if its purpose is to indicate the same data value. http://www.nanum.org/eng/main/index.php http://www.1945815.or.kr/ information technology and libraries march 2023 japanese military “comfort women” knowledge graph 6 park and kim 2. metadata elements not used in the actual data were excluded from the model. for example, ged has 88 metadata elements. however, there were no data values for 60 of these elements. table 2 summarizes a list of metadata elements for describing the records of digital archives. a proposed model should be able to represent the context of individual records and their own properties. after investigating semantic relationships between common metadata elements and existing vocabularies, the proposed model is defined. the model reuses existing vocabularies, such as dcmi (dublin core metadata initiative) metadata terms for describing online resources, skos (simple knowledge organization system) for representing taxonomies, ric-o (records in contexts – ontology) for describing digital records, and schema.org for supporting universal search on the web. the basic structure of the japanese military “comfort women” knowledge model is illustrated in figure 1. all records that are digital resources (“#record”) are instances of schema:archivecomponent and represent records provided by each archive. the individual records contain information on several people and organizations. for example, the schema:creator property describes a creator who creates a record, the schema:contributor can be used to represent a person who contributes a record, and the schema:mentions is to represent a thing related to a record. an archive manager who holds or maintains a record can be described using the schema:holdingarchive property, and the archive manager is represented by the schema:archiveorganization class. if the value of each property is a type of organization, then the value of rdfs:range is the schema:organization class.

information technology and libraries march 2023 japanese military “comfort women” knowledge graph 9 park and kim data enrichment and transformation data enrichment refers to the process of appending or otherwise enhancing the collected data with the relevant context obtained from additional sources. in the collected digital records, the entities of person and organization are linked to wikidata (http://wikidata.org) and the enriched information is expanded to a knowledge graph using the rdf extension of openrefine (http://openrefine.org). a total of 654 terms were extracted from the existing archives for people and organizations. after removing duplicates, the dictionary contained 150 people and 312 organizations. for each term in the dictionary, a matching entity is searched for in wikidata. if the entity name matches completely, the uri of wikidata is assigned automatically. thirty-eight percent of people (57) and 28 percent of organizations (88) matched between the dictionary and wikidata. matched entities can be added to the knowledge graph by extracting the properties and values of wikidata. for example, kim bok-dong is linked to wikidata (q16175111), and citizenship, occupation, place of birth, and gender, which did not exist in the collected data, are added to the knowledge graph. as a result, six properties are representing the extended properties were mapped (e.g., citizenship is mapped to fetched from the person and three attributes are obtained from the organization. a total of nine properties were expanded by data enrichment, and vocabularies for schema:nationality). the constructed knowledge graph had 47,499 triples for 3,069 entities. the collected records and information contained in the records included 2,560 objects. the number of entities expanded through wikidata was 145 (88 individuals and 57 entities) and were added to the organization. the enriched entity contained 2,144 explicit statements and 102 inferred statements. as shown in table 3, the total number of triples was 47,327 for explicit statements and 172 for inferred statements. the knowledge graph is published on github (https://github.com/hike-lab/comfortwomen-archives). table 3. statistics of the constructed knowledge graph entities explicit statements implicit statements sum of statements collected entities 2,560

records produced or contributed by o’herne. wed’s record (wednes-demo-368) links jan ruff o’herne with related information (schema:mentions), and a814’s record (a814-107) links jan ruff o’herne as the

associated records. figure 2. semantic relationships of jan ruff o’herne on the knowledge graph. evaluation the evaluation of the constructed knowledge graph was carried out in two ways: 1) discoverability among five archives and the knowledge graph is compared by using several semantic queries, and 2) the fair data evaluation was applied to the knowledge graph and existing digital archives. information technology and libraries march 2023 japanese military “comfort women” knowledge graph 11 park and kim discoverability all queries aim to find out all digital records across five digital archives by using search conditions and are designed by the rdf standard query language (sparql). table 4 is an example query (q3), and the records produced from 1990 to 1994 in digital

condition and information semantically linked to those records. for example, gen had 169 records produced between 1990 and 1994. since the archive did not support the search for a type of a record, it is not possible to specifically search for the record type in q2 and q3. however, in the knowledge graph, the record type is rico:hascontenttypeof; thus, information is expressed at the semantic level, such that 169 related records can be retrieved. q4 and q5 discover entities based on their semantic relations. “ministry of gender equality and family” in q4 is an organization, and each government uses the name of the department slightly differently (e.g., “ministry of gender equality”). q5 discovers different entities in existing archives. the knowledge graph semantically defines the variant of entities and their types. as a result, the knowledge graph provided 104 more search results in q4 and nine more search results in q5 than the existing archives. figure 3. search results

existing archives. findable, accessible, and interoperable follow the fair data principles. all objects of the constructed knowledge graph can be identified by uri, and metadata elements are described with a standard vocabulary, so that the machine can search for digital resources. digital resources in the existing archives are accessible over the web, therefore accessible received a pretty good score. however, access to the metadata of ind ividual records was restricted, as the majority of metadata elements were described as simple strings instead of machine-readable forms. all the information in the knowledge graph has improved accessibility by providing uris to metadata elements. in addition, to avoid being linked to the resources of the existing archive, standardized vocabulary, such as schema.org and dublin core, was applied to increase the connectivity between data, and rich contextual information was provided through semantic linkage with wikidata. as shown in figure 5, the evaluation score of reusable is 0.7, which is 2.9 times better than the existing archives. the metadata elements in the information technology and libraries march 2023 japanese military “comfort women” knowledge graph 13 park and kim knowledge graph clearly describe a license for reuse. in particular, the creative commons license and the korea open government license provide machine-readable uri information to enhance reusability. however, data for which licensing information is not clear or not provided are left blank. in summary, the constructed knowledge graph semantically connects digital resources fragmented in different archives, enables a rich search, and satisfies all fair data indicators. figure 4. results of fair data evaluation of the knowledge graph and existing digital archives. conclusion this study proposed a method for linking and searching digital records from the japanese military “comfort women” digital archive. in korea, materials related to japanese military “comfort women” are managed by several institutions, some of which are provided as digital archive services. however, the existing digital archives describe digital records without common standards or guidelines, and the metadata of individual records are expressed in text format in html documents without explicitly expressing their structure and meaning. therefore, digital records that exist in different digital archives cannot be connected even if they have the same context, such as subject, event, person, or institution. this study proposed a common metadata model for the descriptive metadata of digital records and constructed a knowledge graph in which digital records are semantically interlinked. furthermore, the fair data maturity model was used to evaluate the constructed knowledge graph. the constructed knowledge graph semantically defines the relationship between the various entities included in the records of japanese military “comfort women.” in particular, records existing in a distributed digital archive are expressed as objects that can be identified on the web, so that different records can be explored at a semantic level. the knowledge model proposed herein is the first attempt to describe digital records related information technology and libraries march 2023 japanese military “comfort women” knowledge graph 14 park and kim to japanese military “comfort women”; thus, it can serve as a starting point for discussing a comprehensive model for describing fragmented digital records worldwide. we also apply an open license to disclose all the collected records and construct knowledge graphs for further collaboration. however, there are also considerations for the construction and management of high-quality digital records. first, the records must contain accurate and rich semantic information. the collected digital archives have an average of 16 metadata elements, but because the metadata elements and values differ among institutions, the data accuracy needs to be improved. second, it is necessary to clearly provide conditions for the use of records. most records do not provide a clear license for terms of use. it is important to explicitly express and provide international or korean standard licenses for digital resources. finally, it is necessary to discuss the records of japanese military “comfort women” using open data. the sharing of records and the promotion of information exchange between domestic and international scholars can both be facilitated by the opening of records, which can also play a significant role in the long-term preservation and sharing of records. as a majority of records are fragmented and difficult to discover and manage, it is necessary to find an effective method to preserve the records by opening and sharing them and to lead research cooperation at home and abroad. endnotes 1 chunghee sarah soh, “the korean ‘comfort women’: movement for

article presents a content analysis of academic library instagram accounts at eleven land-grant universities. previous research has examined personal, corporate, and university use of instagram, but fewer studies have used this methodology to examine how academic libraries share content on this platform and the engagement generated by different categories of posts. findings indicate that showcasing posts (highlighting library or campus resources) accounted for more than 50 percent of posts shared, while a much smaller percentage of posts reflected humanizing content (emphasizing warmth or humor) or crowdsourcing content (encouraging user feedback). crowdsourcing posts generated the most likes on average, followed closely by orienting posts (situating the library within the campus community), while a larger proportion of crowdsourcing posts, compared to other post categories, included comments. the results of this study indicate that libraries should seek to create instagram posts that include various types of content while also ensuring that the content shared reflects their unique campus contexts. by sharing a framework for analyzing library instagram content, this article will provide libraries with the tools they need to more effectively identify the types of content their users respond to and enjoy as well as make their social media marketing on instagram more impactful. introduction library use of social media has steadily increased over time; in 2013, 86 percent of libraries reported using social media to connect with their patron communities.1 the ways in which libraries use social media tend to vary, but common themes include marketing services, content, and spaces to patrons, as well as creating a sense of community.2 even with this wealth of research, fewer studies have examined how libraries use instagram, and those that do often utilize a formal or informal case study methodology.3 this research seeks to fill that gap by examining the types of content shared most frequently by a subset of academic library instagram accounts. although this research focused on academic libraries, its methods and findings could be leveraged by educational institutions and non-profits in their own investigations of instagram usage and impact. literature review since its inception in 2010, instagram’s number of account holders has been steadily increasing. by 2019, more than one billion user accounts were active each month, making it the third most popular social media network in the world, and the pew research center has reported that instagram is the second most used social media platform among people ages 18-29 in the united states, after facebook.4 instagram has estimated that 90 percent of user accounts follow at least one business account.5 previous research has also shown that individuals who use instagram to follow specific brands have the highest rates of engagement with, and commitment to, those

brands when compared to users of other social media platforms.6 though businesses are fundamentally different in the products or services they are trying to market, academic libraries share a desire to provide information to, and engage with, their followers. as such, in the past decade, libraries have begun to adopt instagram as a way to market their libraries and interact with patrons.7 however, methods and parameters for libraries’ use of instagram vary across types of libraries and even within specific library types.8 research has demonstrated that academic libraries’ use of social media, including instagram, is often for the purpose of increasing the sense of community among librarians and patrons by marketing the library’s services and encouraging student feedback and interaction.9 similarly, harrison et al. discovered that academic library social media posts reflected three main themes: “community connections, inviting environment, and provision of content.”10 chatten and roughley have also reported that libraries’ use of social media ranges from providing customer service to promoting the library and building a community of users.11 indeed, when comparing modern social networking systems, such as instagram, to older platforms, such as myspace, fernandez posited that today’s popular social media sites encourage networking and are especially suited to creating community.12 ideally, community engagement in the virtual social media environment would encourage more patrons to enter the library and thus engage in more face-to-face encounters.13 libraries’ methods for measuring the success of their social media engagement are as varied as the ways in which they use social media. assessment of libraries’ social media efficacy is tricky, and highly variable from institution to institution. hastings has cautioned that librarians should recognize that patrons both actively and passively interact with social media content.14 for this reason, while a large number of comments or likes may be identified as positive markers for active engagement, passive forms of engagement, such as the number of times a post appeared in users’ instagram feeds, may also be relevant.15 therefore, when librarians measure the success of an instagram post by examining only the number of likes and comments, they should be aware that they are measuring a very specific type of engagement: one which, on its own, may not determine a post’s full reach or effectiveness. other ways to measure engagement include monitoring how the number of people subscribed to an account changes over time, evaluating reach and impressions,16 or analyzing the content of comments (a type of qualitative measure that may indicate the type of community developing around the library’s social media). despite, or perhaps because of, the general excitement surrounding the possibilities that libraries’ engagement with social media can produce, very little has been written about how different types of libraries (such as academic libraries, law libraries, public libraries, etc.), or libraries in general, use these platforms.17 additionally, many librarians may lack expertise in marketing, including those who are managing social media accounts.18 as social media culture continues to evolve, librarians should move toward a more targeted and pragmatic approach to their instagram practices. this refinement in social media practices may enable libraries to develop more structure, so that they may create and share the type of content that would achieve their desired result at a given time. however, in order to develop this kind of measured approach, it is necessary for researchers to first analyze libraries’ current instagram practices to determine how posts are being used and the outcomes they generate. one effective method of analyzing instagram content centers on coding and classifying images. while many such schemas have been developed for analyzing images posted by instagram users and businesses, transferring these schemas to academic contexts has been difficult. 19 to address information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 3 this gap, stuart et al. adapted a schema that had been used to examine how “news media [and] non-profits,” as well as businesses, used instagram.20 this new schema allowed stuart et al. to classify instagram posts produced by academic institutions in the uk and measure the effect of these universities’ attempts to engage with students via instagram.21 stuart et al.’s schema, which classified instagram images into six categories (orienting, humanizing, interacting, placemaking, showcasing, and crowdsourcing), was the basis for the present study.22 methods research questions the impetus for this study was to learn more about how academic libraries use instagram to connect with their campus communities and promote their services and events. the authors of the present study adapted the research questions posed by stuart et al. to reflect academic library contexts:23 • rq1: which type of post category is used most frequently by libraries on instagram? • rq2: is the number of likes or the existence of comments related to the post category? identifying a sample population this study investigated a small subset of academic institutions: the university of idaho’s sixteen peer institutions. these peers have similar “student profiles, enrollment characteristics, research expenditures, [or] academic disciplines and degrees”; each is designated as a land-grant institution; and the university of idaho considers three to be “aspirational peers.”24 after selecting this population, the authors investigated the library websites of each of the sixteen peer institutions to determine whether or not they had a library-specific instagram account. when a link was not available on the library websites, the authors conducted a search within instagram as well as a general google search in an attempt to identify these instagram accounts. of the university of idaho’s sixteen peer institutions, eleven had active, library-specific instagram accounts. data collection the authors undertook manual data collection between november and december 2018 for these eleven library instagram accounts. initial information about each instagram account was gathered prior to the study on october 23, 2018: the date of the first post, the total number of posts shared by the account, the total number of followers, and the total number of accounts followed. for each account, the authors identified posts shared from january 1, 2018, to june 30, 2018. the “print to pdf” function available in the chrome browser was used to preserve a record of the content, in case the accounts were later discontinued while research was underway. if a post included more than one image, only the first image was captured in the pdf and analyzed. to organize the 3 77 instagram posts shared within this timeframe, the authors assigned each institution a unique, fivedigit identifier; file names included this identifier as well as the date of the post (e.g. , 00004_igpost_20180423). this file naming convention ensured that posts were separated based on institution and that future studies could use the same file naming convention, even if the sample size increased significantly. the authors added the file names of all 377 instagram posts to a shared google sheet, and for each post they reported the kind of post (photo or video), the number of likes, and whether comments existed. information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 4 research data analysis content analysis this project adapted the coding schema stuart et al. employed to investigate the ways in which uk universities used instagram.25 expanding on research by mcnely, stuart et al. employed six instagram post categories: orienting, humanizing, interacting, placemaking, showcasing, and crowdsourcing.26 for the purposes of the present study, the authors used the same category names when coding library instagram posts. however, they updated and adapted the descriptions of each category over the course of two rounds of coding to better reflect academic library contexts (see table 1). within this coding schema, the authors elected to apply only a single category name (i.e., a code) to each library instagram post. interrater reliability during the first round of coding, the authors selected two or three institutions every month, independently coded the posts based on the initial adapted schema, met to discuss discrepancies, and identified the final code based on consensus.27 however, during these discussions, it became evident that there was substantial disagreement concerning how specific categories were interpreted. to examine the impact of this disagreement, the authors calculated fleiss’ kappa, which can be used to assess interrater reliability when two or more coders categorically evaluate data.28 although this project’s fleiss’ kappa (0.683554901) was relatively close to a score of 1.0, demonstrating moderate agreement between each of the three coders, the authors recognized that additional fine-tuning of the adapted coding schema would allow for a more accurate representation of the types of content shared by academic libraries. after updating the schema (table 1), a small sample of collected instagram posts (20 percent, or 76 posts) was randomly selected for independent recoding by each of the authors. again, after coding this random sample individually, the authors met to seek consensus. anecdotal feedback from the coders, as well as an increase in the project’s fleiss’ kappa (0.795494117), demonstrated that the updated coding schema was more robust and representative. based on this evidence, the authors randomly distributed the remaining 301 posts amongst themselves; each post was coded by one author. information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 5 table 1. coding schema for library instagram

likes, comments, views | doney, wikle, and martinez 7 category description example1 showcasing posts that highlight library or campus resources, services, or future events. can include current or on-going events if people are not the focus of the image (e.g. exhibit, highlight of collection, etc.). these posts can also present information about library operations, such as hours and fundraising. posts can also entice their audience to do something, outside of instagram, such as visit a specific website. results general data about the library instagram accounts as of october 23, 2018 (the date this initial information was gathered), the eleven academic library instagram accounts had shared a combined 3,124 posts. most libraries created their instagram accounts and started posting between 2013 and 2016, but one library shared a post in 2012 and one created their account in april 2018. since the date of their first post, each account had shared 284 posts on average, while the actual number of posts shared across accounts ranged from 62 to 520. the number of followers and accounts followed across these eleven accounts ranged from 115 to 1,390 and 65 to 2,717, respectively. between january 1, 2018 , and june 30, 2018, these eleven library instagram accounts shared a total of 377 posts. the number of posts shared by each account during this time period ranged from four to 57, with an average of 34 posts. rq1: which type of post category is used most frequently by libraries on instagram? of the 377 posts analyzed, 359 included photos and 18 included videos. more than 50 percent of posts shared were coded as showcasing, with humanizing (18 percent) and crowdsourcing (9.8 percent) being the next most common categories (see table 2), although data demonstrated that individual libraries differed in their use of specific post categories (see table 3). when examining frequency based on category of post, the authors identified slight differences between video and photo posts. as with photos, the majority of videos (55.6 percent) were still coded as showcasing; however, the second most common post category for videos was interacting (16.7 percent). information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 8 table 2. number and percentage of posts by category for posts with photos or videos

comments related to the post category? number of likes by category the results of the coding process also indicated that the number of likes differed based on the category of post. when examining photo posts, the authors noted that every post received at least five likes, with most posts receiving between 20-39 likes (see table 4). on average, crowdsourcing information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 9 photo posts generated the highest average number of likes across all categories, followed by orienting and placemaking posts (see table 5). however, it is important to recognize that crowdsourcing posts often asked visitors to participate in a post by “liking” it, often with the chance to win a library-sponsored contest, which may partially explain the higher average number of likes. table 4. number of posts by category and range of likes for posts with photos (does not include posts with videos) range of likes category

metric for engagement with instagram posts. data demonstrated that 78.9 percent of crowdsourcing posts included information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 10 comments, while a much lower percentage of placemaking (30.3 percent), orienting (28.6 percent), and humanizing (26.5 percent) posts generated this type of engagement (see table 6). as with the data on the number of “likes,” many crowdsourcing posts encouraged visitors to comment on a particular post, at times with an incentive connected to this type of engagement. table 6. presence of comments by category for posts with photos or videos category number of posts with comments number of posts without comments total number of posts percentage of posts with comments

noted previously, the post category used most frequently by these eleven libraries on instagram was showcasing (51.5 percent). the fact that libraries were more likely to share this type of content—which highlighted library resources, events, or collections—is understandable, as library promotion is one of the foundational reasons libraries spend the time and effort required to maintain social media accounts.29 this finding differs substantially from previous research with uk universities, which classified only 28.8 percent of posts as showcasing.30 when examining other post categories, it also became clear that uk universities shared humanizing posts more frequently (31 percent) than the eleven libraries (18 percent) included in this study.31 although the results of this study demonstrated that showcasing posts were shared most often, the data also indicates that showcasing posts were neither the category with the most likes on average nor the category that received comments most often. crowdsourcing posts were the category with the highest average number of likes (53.6) with orienting posts coming in at a close second (50), followed by placemaking (46.9) and humanizing (39.9) posts. showcasing posts, along with interacting posts, only generated slightly more than half the number of likes on average, when compared to the other categories (27.6 and 27.8, respectively). the category with the largest proportion of comments was crowdsourcing posts, with 78.9 percent of posts in this category generating comments from visitors. however, this result is likely skewed, as one of the library instagram accounts had exceptionally successful crowdsourcing posts, which often included a giveaway or other incentive for participation. in fact, when this institution was removed from the data set, only six crowdsourcing posts remained, two of which generated information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 11 comments. to better determine whether crowdsourcing posts are always this effective at generating engagement, it would be necessary to code a larger sample of instagram pos ts. it is clear that while showcasing posts were the most common among the instagram accounts analyzed, they also received the lowest number of likes, on average, and generated comments less frequently than all but one post category. while this may seem disheartening, it is important to remember that the showcasing category includes informational posts that convey library hours, services, or closures; this information that may be effectively relayed to users without necessitating an active response in the form of likes and comments. therefore, one might use different criteria to determine the success of showcasing posts, perhaps examining instagram data related to reach (the total number of unique visitors that view a post) and impressions (the total number of times a post is viewed).32 data on reach and impressions are only available to instagram account “owners.” in the current study, the authors did not quantify these types of engagement as their goal was to evaluate the content and metrics available to all instagram users, rather than the data that was only available to the “owners” of these library instagram accounts. in addition to answering the research questions, coding these instagram posts prompted several new questions regarding the types of information libraries and other institutions share online. one such question includes: with both universities and academic libraries working with students, why did academic libraries share a smaller percentage of interacting posts than uk universities? 33 additional research is needed to answer this question, but anecdotally, this difference may be related to the fact that universities, as a whole, have a larger number of opportunities to promote and share instances of interaction via instagram than libraries. for example, general university instagram accounts often include photos of students and affiliates interacting at large scale events such as sports games, musical performances, and other student gatherings that take place across campus. library-specific accounts on the other hand, have fewer opportunities to post photos that capture individuals “interacting” candidly. further, the fact that libraries tend to be proponents of privacy rights may inhibit library staff from taking photos of their users and sharing them online without first getting permission. therefore, differences related to the number of events and the organization type may contribute to whether or not universities and libraries share interacting posts; more research is needed to examine this hypothesis. another issue that arose during coding was that, if not for their inclusion of a request to comment, many crowdsourcing posts could have been classified under other categories. if an account follower looked only at the photos included in many of the crowdsourcing posts without reading the captions, they may not interpret those posts as crowdsourcing. therefore, a future research project might examine whether applying secondary categories to crowdsourcing posts, as a means of further classifying images and not just their captions, could generate a more comprehensive picture of what libraries are sharing on their instagram accounts. the authors also discovered that a majority of the library instagram posts included in this sample contained humanizing elements. almost all posts attempted to convey warmth, humor, or assistance, and therefore had the potential to be classified as humanizing. to successfully adapt stuart et al.’s coding schema for academic library instagram accounts, the authors specified that a post had to have both a humanizing caption as well as a humanizing photo to be coded as such.34 as with crowdsourcing posts, adding secondary categories to humanizing posts could better reflect the dual nature of this content and help future coders more accurately interpret the types of content shared by academic libraries. information technology and libraries september 2020 likes, comments, views | doney, wikle, and martinez 12 limitations and future research the number of library instagram accounts selected as well as the use of a six-month timeframe were limitations of the current study. in the future, selecting a larger sample size and a different group of academic libraries would serve to advance the discipline’s understanding of the types of content shared by academic libraries and how users interact with these instagram posts. additionally, collecting instagram posts shared during an expanded timeframe could allow researchers to explore whether library instagram accounts consistently share the same types of content at various points throughout the year. as mentioned in the discussion section, future research could also include adding secondary categories to posts, which would allow researchers to gather more granular information about the types of content shared and the relationships between post category, comments, and likes. lastly, to better understand the post categories that generate the greatest engagement, collaborative research between institutions could allow researchers to gather and analyze metrics that are only available to account owners, such as impressions and reach. with this type of collaboration, researchers could also investigate how social media outreach goals influence the types of content shared on library instagram accounts. for example, researchers could conduct interviews or surveys with libraries and ask questions such as: what does your library hope to accomplish with its instagram account, who are you attempting to reach, how do you define a successful post, what metrics do you use to evaluate your instagram presence, and do your social media outreach goals influence the types of content shared on instagram? pursuing these types of questions, in addition to examining the actual content shared, would allow researchers to gain a more complete picture of what a successful social media presence looks like for an academic library. conclusion this research provides initial insight into the instagram presence of a subset of academic libraries at land-grant institutions in the united states. expanding on the research of stuart et al., this project used an adapted coding schema to document and analyze the content and efficacy of academic libraries’ instagram posts.35 the results of this study suggest that social media accounts, including those used by academic libraries, perform better when they reflect the community the library inhabits by highlighting content that is unique to their particular constituents, rather than simply functioning as another platform through which to share information. this study’s findings also demonstrate that academic libraries should strive to create an instagram presence that encompasses a variety of post categories to ensure that their online information sharing meets various needs. information technology and libraries september 2020

promote reading; however, there are challenges to increasing the use of these library platforms, such as poor promotion and low reader participation. therefore, these libraries need to find ways of dealing with the behavior characteristics of social network readers. in this study, a simulation experiment was developed to explore the behaviors of readers seeking book reviews and opinions on social networks. the study draws on social network theory to find the causes of students’ behavior and how these affect their selection of information. finally, it presents strategies for peer reading promotion in university libraries. introduction over the last decade, social media has made an impact on almost every aspect of daily life. university libraries have gradually accepted social media as a way of promoting their services, and almost every university library in the people’s republic of china has its own social media accounts. however, there are challenges to increasing libraries’ use of social media, such as poor promotion and low reader participation.1 university libraries cannot depend only on promoting reading through readers’ unenthusiastic use of social media tools, as constructive engagement with social networks requires users’ participation, dominance, and construction.2 therefore, as a baseline, university libraries must take into consideration their readers’ social attributes and then make full use of the mutual cooperation and sharing mechanisms between peers so that readers can become more involved in the use of these platforms that promote reading. in the current study, a free simulation was conducted wherein participants were required to complete a preferential choice task while browsing a book review survey that was integrated with social media platforms.3 finally, we provide some suggestions to promote reading. literature review university reading promotion our review of literature on the promotion of university reading reveals three main research perspectives. the first perspective focuses on libraries. there is some evidence to suggest increasing enthusiasm for reading programs within universities.4 rodney detailed the experiences of a library at a small liberal arts university that launched a one book, one community program.5 hou emphasized the dominant position of university reading in reading promotion and put forward specific promotion strategies.6 li et al. established a subscription digital service system for reading promotion in universities that provided personalized services for users.7 the national mailto:jyp@zjut.edu.cn mailto:chixiaobo@zjut.edu.cn mailto:jljly@zju.edu.cn mailto:jljly@zju.edu.cn mailto:cyq77@zjut.edu.cn mailto:beckygoodly@163.com information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 2 resource center for the first-year experience and students in transition hosts a discussion site and has compiled a list of institutions reporting first-year summer reading programs along with a list of book titles used in the programs.8 appalachian state university also has an active university reading program discussion list.9 college reading experience programs have the potential to bring disparate disciplines and college departments together in ways that extend student learning and engagement beyond the classroom. it could be argued that librarians are one group of natural “boundary spanners.”10 gustavus adolphus college has compiled a lengthy list of links to universities that participate in the first-year experience. querying this list suggests that there is a growing number of reading programs on college campuses and librarians are increasingly finding a role in their development and delivery.11 the second perspective focuses on readers. for instance, zhou et al. analyzed users’ reading needs and proposed ideas of how universities could promote reading through the use of questionnaires.12 based on self-determination theory, wei et al. constructed an index of students’ and teachers’ motivation and participation in reading promotions in libraries by using questionnaires. their factor analysis of readers’ reading psychology from the aspects of information value, social sharing, interest, cognition, and emotional entertainment concludes that the theme, intelligence, and interactivity of college reading promotions are significant. 13 dali made specific recommendations on how to give reading practices in academic libraries a boost and a new direction through the lens of the differentiated nature of readerships on campuses.14 the third perspective focuses on cultural constructions in colleges. boff et al. studied the practical activities they termed as library participation in “campus reading experience” (cre) at two american community colleges and two four-year institutions in the united states.15 their research pointed out the importance of reading promotion activities in the cultural constructions of colleges and universities. moreover, it presented efficient suggestions of how librarians can hold reading promotion activities on campus and how librarians can play a more positive role in presenting reading promotion plans to their administrations. marcoux et al. emphasized the vital status of canadian college libraries in various subject areas and cultural dominance in colleges and insisted that reading promotion should be enforced by bringing together colleges, teachers, and students.16 peer education in university libraries since the 1970s, university libraries have experimented with making students an extension of reference services and part of established peer instruction services. for example, at california state university, fresno, student assistants were recruited to work on the reference desk and answer directional and simple reference questions.17 the university of michigan in ann arbor developed its peer information counseling program in 1985 to focus on the retention of minority students.18 the university of wisconsin-parkside and binghamton university in new york employ student peers to provide instructional support.19 all these programs incorporate peer tutoring models developed specifically for their settings. there are many practical projects in which libraries provide instruction to peer readers, such as the peer practical project at wabash college, the student assistant project at valparaiso university, the student consultant project at the university of new mexico, the curriculum consultant project at the university of new hampshire, and the student assistants project at utah state university. 20 surveys of targeted students in these programs revealed that students were more likely to ask questions of student assistants than librarians. descriptions of the training in these projects information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 3 emphasized knowledge of the library’s resources, with little or no explanation of incorporating peer-learning principles.21 by 2010, libraries acknowledge that peer learning provides an opportunity to further solidify the information literacy skills of all students. programs such as the library instruction tutor project at the university of new mexico and research mentors at the university of new hampshire were designed with a focus on taking advantage of the uniqueness of the peer-to-peer relationship, rather than replacing reference services.22 the librat program at california polytechnic state university trained students to provide single-shot information literacy instruction. student endorsement of peer-led sessions provides supportive evidence that participating attendees perceive this type of session as useful and valuable.23 to summarize, university libraries have identified that harnessing the uniqueness of peer relationships is an effective way to engage students in learning.24 social reading promotion the first published papers regarding the use of facebook by libraries and librarians appeared in 2006.25 up to that time, most scholars defined social reading as sharing theoretical research but had not yet explored its relationship to social media. for instance, zhang et al. suggested that classic books and other resources should be aimed more accurately at potential users, and the convenience of the connection between a library and its users in the social media environment should be fully utilized in order to understand the personal needs of users.26 yang et al. explored the relationship between users who engage in social reading and reading resources by analyzing it from the perspective of users.27 white et al. explored how social networks promote reading and studying and found that social media can promote users’ selection, critiques, and discussions in the reading context, which are part of the process of constructive studying.28 similarly, asteman et al. investigated the impact of users’ discussions on reading participation and reading promotion by using facebook as a research target, and they proved that users’ discussions on social reading were beneficial to reading, studying, and understanding complex scientific topics.29 some researchers have explored the resources recommending methods and algorithms for social reading. take kochitchi et al.’s research as an example: they built a visual analysis system to construct the relationship between user characteristics and resources by extracting social reading tags and user interaction behavior characteristics. 30 huang et al. proposed an efficient method for recommending information among social network groups.31 some scholars put particular emphasis on researching user services. for instance, liu et al. created reading review flows to help improve users’ reading ability and optimize the reading experience by analyzing users’ needs on social platforms.32 fox subdivided users on social media platforms into three categories—passive, active, and interactive—and summarized that users’ standardized behaviors can effectively enhance user interaction.33 yao et al. studied the data gathered from practical activities such as information posts and book retrieval through social reading platforms at the tsinghua university library.34 information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 4 methods research questions existing studies on social reading promotion in libraries have mainly explored how to use social media platforms to promote and develop reading promotion services. however, few scholars have explored the reader patterns of those seeking opinions within social networks. this study explored the effects that peers have on each other as opposed to services provided by university libraries and addressed the following three questions: 1. do readers value the opinions of peers on social networks? 2. what tendencies do readers exhibit when seeking opinions on different types of literature? 3. how does social capital influence readers’ tendencies when those readers are seeking opinions? social capital refers to the potential value of social relations and includes two key dimensions: structural and relational.35 social structure can be characterized by quantity and configuration.36 with respect to quantity, the more social ties one has the potential to activate, the more information resources can be transferred.37 the configuration of social capital means that it is higher when a network’s structure is more sparse.38 relational capital refers to the potential value associated with the quality of social relationships which are created and embedded by network peers and can be utilized by network friends.39 previous studies have used different social attributes to describe relational capital, including homogeneity, trust, expertise, power, and closeness.40 study design we used a questionnaire applet and designed a survey of book reviews to explore patterns in the way readers seek information on books through social networks and the factors that influence readers when they adopt others’ opinions. as an initial step, we recruited 300 college student participants from 15 colleges and universities. these students, from the wechat group of the eighth national mechanical design competition for college students, expressed interest in the study. the students were offered three lists of books, categorized as leisure literature, mechanical literature, and information resources utilization literature. there were 10 books in every list, and the books were selected from a 2019 lending list compiled by five colleges and universities. participants were asked to log in to our survey using their wechat credentials. they were required to write reviews for the books that they had read, and they were encouraged to recommend similar literature and write reviews for those books as well. meanwhile, 30 librarians were also invited to write reviews for the books on the lists (see fig. 1). information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 5 figure 1. the book review steps. to keep a representative sample, we adopted stratification and divided participants into different non-overlapping homogenous groups. we set up six groups with similar scales according to the number of wechat friends that the readers had within the 300-student sample. readers in the first group did not have any friends. readers in the second group had one or two friends. readers in the third group had three or four friends. readers in the fourth group had five or six friends. readers in the fifth group had seven to eleven friends. readers in the sixth group had twelve or more friends. subsequently, we randomly invited 15 readers from every group to complete the following steps: (1) complete an online questionnaire that measured their relational capital (see table 1 and fig. 2) and (2) make references to others’ reviews and select books that they intended to read (see fig. 2). information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi,

promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 7 figure 2. selecting the books. data collection measurement of readers’ behavior when seeking opinions. a book review applet (with wechat’s questionnaire function) was incorporated to record the number of times a reader looked at reviews from peers and librarians (see fig. 3). information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 8 figure 3. measurement of readers’ behavior when seeking opinions. note: when readers wanted to refer to other people’s comments, the applet allowed them to choose either classmates’ or librarians’ reviews. readers could browse the comments through a drop-down menu, and the number of reviews read by the respondents was recorded. measurement of structural capital. the scale of a reader’s structural capital was related to the number of wechat friends they had.41 drawing on the extant literature, we computed network sparseness by dividing the network’s effective size by the overall size. network effective size is the average number of wechat friends within the sample set of 300 people. measurement of relational capital. we used the three variables of professional skills, similarity, and intimacy to measure social relationships.42 data were gathered from the online questionnaire (see table 1). experiment validity reliability analysis. we performed measurement validity checks on the three variables applied in the measurement of relational capital. table 2 shows the evidence of satisfactory convergence and discriminant validity. table 2. reliability analysis results cronbach’s alpha std. cronbach’s alpha projects .811 .811 12 factor analysis. we tested whether it was scientifically meaningful to consider network scale, network sparseness, and relational capital as independent variables in respectively analyzing two information technology and libraries march 2021

tables 3 and 4 show the results of the kaiser-meyer-olkin (kmo) spherical test and bartlett’s test, which show that factor analysis is suitable, and further analysis can be performed. table 3. kmo

consulted librarians. the results are shown in table 5. in total, readers sought opinions from peers 1,374 times (70.9%), and from librarians 563 times (29.1%). for leisure literature, mechanical literature, and information resources utilization literature they sought opinions from peers 422 times (85.3%), 519 times (88.3%), and 433 times (50.7%), respectively. from these results, it can be surmised that readers tend to seek opinions from peers. table 5. comparison of sources consulted by readers seeking opinions leisure mechanical information resources utilization total reviews browsed

relationship between readers’ behavior of seeking opinions and social capital. results are shown in table 6. according to the t-test, given the significance level of 0.10, the significance probability of the three variables was less than 0.10 for both the times that readers sought peer opinions and the times that they consulted librarians. table 7 shows the introduction and elimination process of variables in the process of stepwise information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 10 regression. the analysis

scale, network sparseness relational capital dependent variable: seeking librarians’ opinions network scale, relational capital network sparseness according to the analysis results, we can draw some conclusions. first, the number of times readers sought opinions from peers was in proportion to network sparseness. in other words, the higher the number of readers’ online peers, the lower the network sparseness and the more they sought advice from their peers. second, the number of times readers sought librarians’ opinions was inversely proportional to their network scale and relational capital. this means that readers tended not to seek opinions from librarians if they had more network peers and more relational capital. information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 11 according to further analysis of tables 6 and 7, there are two equations that can derived: 1. regression equation of readers seeking opinions from peers: where y1 represents seeking peer opinions and x1 and x2 represent network scale and network sparseness, respectively. 2. regression equation of readers seeking opinions from librarians: where y2 represents seeking librarian opinions and x1 and x3 represent network scale and relational capital, respectively. based on the two regression equations, it can be observed that the number of peers’ reviews consulted increases by 13.9% for each point increase in network scale and by 35.7% for each additional unit of network sparseness. the number of librarians’ reviews consulted decreases by 60.7% for each point increase in network scale and by 70.7% for each additional unit of relational capital. discussion the value of peers according to the results in table 5, readers tend to seek opinions from peers. this is mainly because familiar information sources can provide more diagnostic help.43 meanwhile, the cognitive effort required to process such information is lower and information is easier to understand. research on peer education also shows similar findings. jane piaget and lev vygotsky found that it is easier to build partnerships among children than among children and adults. moreover, children are more willing to negotiate and theorize with partners who are not authoritative. in this social media age, the value of peers is even more pronounced. therefore, libraries should recognize this, recruit influential readers for reading promotion, and utilize the influence of peer social networks to spread information related to the promotion of reading. opinion seeking tendency of different types of literature information the participants in this study were university students majoring in mechanical engineering disciplines across several different universities. this means that they had similar backgrounds, experiences, and feelings as they participated in the mechanical design competition. under these circumstances, it would be expected that they had close peer relationships. behavioral science research proves that if the communicator and the receiver have similar experiences, are concerned about similar things, and face similar problems, the receiver is more likely to accept information from the communicator. this viewpoint is consistent with the standpoint proposed by psychological models in which relevant sources of information are more frequently activated. 44 therefore, the result that readers are more willing to seek opinions from peers is supported. the result regarding information resources utilization literature shows similar numbers in terms of seeking opinions from peers and from librarians, and the number seeking from librarians is slightly higher. this may be because libraries are the literature and information resource centers information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 12 of universities, and readers trust the professional abilities of librarians and are willing to seek their help with regard to resource utilization. the results indicate that librarians should make efforts to promote the use of information resources. seeking tendency of readers with different social capital in the process of decision-making, readers will look for homogeneous and credible people to assist them in their search for and evaluation of information.45 identity, experience, reading level, and taste in reading are contributing factors to credibility. the more partners, the more the relational capital; if readers have more trustworthy sources of information, they will not turn to librarians for their opinions. information searching is a dynamic and adaptive process. when readers find information that is novel, it has value in decision-making. conversely, when the information is redundant (not novel), it may cause the seeker to stop searching. it is widely acknowledged that sparse social networks reduce the possibility of information redundancy.46 therefore, the sparser the social network, the more likely it is that readers will need peer help. conclusions in this age of social media, university students are accustomed to using social networks. seeking information that complies with their psychological needs is more significant and valuable to them than the value of the information itself. therefore, libraries should make full use of peer influences when employing social media in reading promotion activities. first, university libraries ought to realize their great potential for involving students within the social flow to participate in reading promotion activities. in the digital age, readers’ consciousness is repeatedly awakened. individuality, advocating for information freedom, and improving the flow of information mean that readers are no longer satisfied with passively receiving information and are more willing to actively search out and read information. meanwhile, sharing and interaction can fully meet the desires of individuals to share and communicate as well as meet their psychological need of realizing their self-worth. libraries must understand the characteristics of contemporary university students’ information needs and create a space for readers to take the initiative. only in this way can readers be more than passive recipients of information—they can also be pushers and disseminators of information. bolder attempts at innovation should be applied to reading promotions. in this research, an analysis and exploration were conducted based on the literature, indicating that readers prefer to seek opinions from their own social networks. therefore, the library can make full use of readers’ social network groups when promoting the library’s literature resources. likewise, other services and activities provided by the libraries can be promoted through readers’ social networks. for instance, libraries can invite student volunteers to take part in a new service before launching and then invite them to share their feelings and evaluations through social networks. these types of methods are more efficient than the traditional flyer notification. last but not least, when organizing reading promotion activities, libraries should stay behind the scenes. university libraries can establish a set of systematic peer reading promotion rules, including recruitment, training, and management systems, to build a wide and influ ential reading promotion student volunteer team on social networks. libraries should, however, strengthen the process of monitoring peer reading promotions to prevent negative influences caused by harmful information technology and libraries march 2021 peer reading promotion in university libraries | jiang, chi, lou, zuo, chu, and zhuge 13 information on social media.47 they should pay special attention to the control of social opinion by using the reader volunteer team. in addition, through the monitoring and analysis of data, the strategy and direction of reading promotions can be adjusted over time to improve their pertinence and effectiveness. moreover, libraries should strengthen the effective evaluation of peer reading promotion projects. readers should be involved in the systematic readjustment of traditional reading promotion methods. innovative methods need to be tested in practice s o that libraries can strengthen the effective evaluation of peer projects. limitations and future research there are some limitations in the methodology design, theoretical scope, empirical context, and research perspective in the current study. getting past these limitations can also provide direction for further research. in the methodology, although the sectional sampling method is often adopted, the conclusions of this research make it difficult to disentangle the roles of readers’ social capital from those of opinion seeking. this study explored the correlations between several variables which need to be further investigated by introducing control variables to fully examine the interactions between the variables. in theory, this research focused on analysis of the rule that readers will seek opinions through social networks, which reflects the behavior observed in information searching and browsing. readers then need to decide whether to use the information they find. these two behaviors are related and, based on this research, we need to further explore readers’ adoption behavior to better guide reader service work in libraries. in the empirical analysis, it is worth further considering how the various efforts undertaken by university libraries have promoted information channels. the participants in this study were university students majoring in mechanical engineering disciplines. however, students in different majors may exhibit different information selecting behavior, and this deserves further analysis and exploration. this study compared the influence of peers’ and librarians’ opinions on readers. however, how do readers feel about opinions from peers as compared to those from librarians? what is the impact of students preferring to use their social networks instead of librarians for information retrieval? is there a difference in the adoption of peer opinions by readers in different social media contexts? these questions deserve further study to fully understand the impact of social networks on read er opinion-seeking behavior. acknowledgements this work was supported by the humanities and social

academic templates | peterson 217 academic web site design continues to evolve as colleges and universities are under increasing pressure to create a web site that is both hip and professional looking. many colleges and universities are using templates to unify the look and feel of their web sites. where does the library web site fit into a comprehensive campus design scheme? the library web site is unique due to the wide range of services and content available. based on a poster session presented at the twelfth annual association of college and research libraries conference in minneapolis, minnesota, april 2005, this paper explores the prevalence of university-wide academic templates on library web sites and discusses factors libraries should consider in the future. c ollege and universities have a long history with the web. in the early 1990s, university web sites began as piecemeal projects with varying degrees of complexity—many started as informational sites for various technologically advanced departments on campus. over the last decade, these web sites have become a vital part of postsecondary institutions and one of their most visible faces. academic web sites communicate the brand and mission of an institution. they are used by prospective students to learn about an institution and then used later to apply. current students use them to pay tuition bills, register for classes, access course materials, participate in class discussions, take tests, get grades, and more. online learning and course-management software programs, such as blackboard, continue to increase the use of web sites. they are now an important learning tool for the entire campus community and the primary communication tool for current students, parents, alumni, the community, donors, and funding organizations. web site standards have developed since the 1990s. usability and accessibility are now important tenets for web site designers, especially for educational institutions. as a result, campus web designers or outside consultants are often responsible for designing large parts of the academic web site. as web sites have grown, ongoing maintenance is an important workload issue. databases and other technologies are used to simplify daily updates and changes to web sites. this is where the academic template fits in. an academic template can be defined as a common or shared template used to control the formatting of web pages in different departments on a campus. generally, administrators will mandate the use of a specific template or group of templates. this mandate includes guidelines for such things as layout, design, color, font, graphics, and navigation links to be used on all web pages. often, the templates are administered using content management systems (cmss) or web development software such as macromedia’s contribute. these programs give different levels of editing rights to individuals, thus keeping tight control over particular web pages or even parts of web pages. academic templates give the web site administrator the ability to change the template and update all pages with a single keystroke. for example, the web site administrator may give editing rights to content editors, such as librarians, to edit only the center section of the web page. the remaining parts of the page such as the top, sides, and bottom are locked and cannot be edited. the result of using templates is that the university web site is very unified and consistent. this is particularly important in creating a brand for the university. well-branded institutions have the opportunity to increase revenue, improve administration and faculty staffing, improve retention, and increase alumni relationships.1 but what about the library? libraries are one of the most visited web pages on a university’s web site.2 thus, the design of the library page can be crucial to a well-designed academic web site. the library web site can set a tone for an institution and help prospective students get a feel for the campus. belanger, mount, and wilson contend it is important for the image of an institution to match the reality.3 if there is discord between the two, students may choose an inappropriate college and quickly drop out, lowering a campus’s retention data. the library web site can also be important in the recruitment of new faculty members. in addition, libraries use their web sites for marketing, public relations, and fund-raising for the library.4 library web sites are crucial to delivering data, research tools, and instruction to students, faculty, staff, and community patrons. more than 90 percent of students access the library from their home computers, and 78 percent prefer this form of access.5 today, the web site connects users with article citations and databases, library catalogs, full-text journals, magazines, newspapers, books, videos, dvds, e-books, encyclopedias, streaming music and video, and more. users access subject-specific research guides, library tutorials, information-literacy instruction, and critical evaluation tools. services such as interlibrary loan (ill), reference management programs such as endnote or refworks, and print and electronic reserves are also used via the web. users get help with doing research by e-mail and virtual chat. in addition, libraries are digital repositories for a growing number of digital historic documents and archives. academic web site design and academic templates: where does the library fit in? kate peterson kate peterson (katepeterson@gmail.com) is an information literacy librarian at capella university, minneapolis, minnesota. 218 information technology and libraries | december 2006 how common are academic templates in library web sites? what effect do they have on the content and services provided by libraries? ■ methods for the purposes of this study, a list of doctoral, master’s, and bachelor of arts (ba) institutions (private and public) based on the carnegie classification of institutions of higher education was created and a random number table was used to select a sample of web pages (n=216).6 home pages, admissions pages, departmental pages, and library web pages were analyzed. a similarly sized sample of each type was selected to give a broad overview of trends—18 percent of doctoral institutions (n=47), 19 percent of master’s institutions (n=115), and 23 percent of ba institutions (n=54). the following questions were asked: ■ does the college or university web site use an academic template? ■ if yes, is the library using the template, and for how much of the library web site? ■ to what extent is the template being used? primarily, a web site was determined to be using an academic template based on the look of the site. for example, if the majority of the web elements (top banner, navigation) all matched, then the web site was counted as using some sort of template. use and nonuse of content management system (cms) software behind the web site was not considered in this study—only the look of the web site. ■ results a majority of college and university web sites (94 percent) use an academic template. fifty percent of the libraries surveyed use the academic template for at least the library’s home page. of that number, about 34 percent of libraries use the template on a majority of the library pages. roughly 44 percent of the total libraries surveyed did not use the academic template, and approximately 5 percent of academic web sites do not use any sort of unified academic template. smaller ba institutions are more likely to use the academic template on multiple library pages than doctoral institutions, which tend to have their own library design or template (see table 1). for those libraries that did not use the academic template on every library page, the most commonly used elements template were the top header (which often has the university seal or an image of the university), the top navigation bar (with university-wide links), and the bottom footer, which often contains the university address, privacy statement, or legal disclaimers. less frequently used elements were the bottom navigation bar, and the left or right navigation bar with university-wide links (see tables 2–3). ■ discussion while many colleges and universities use academic templates, only about half of their libraries follow suit. libraries using the template often use selected parts of the template, or only use the template on their home page. though not considered in this study, there may be a correlation between institution size and template use, as larger institutions are more likely to have library web designers and thus use the academic template only on the library’s home page. while academic templates can cause libraries many problems, there are also many benefits to be considered. ■ problems with academictemplates on library web sites the primary concern with any template is how much space is available for content. for example, there may be a very small box for the page content while images, banner bars, and large navigation links may take up most of the real estate on the page. this problem can be exacerbated for libraries because there are so many different types of content such as the library catalog, databases, tutorials, forms, ill, and other library services delivered via the web. libraries can be caught between the design imposed by the academic template and the rigid size requirements from outside vendors such as database companies, ill or reserve modules, federated search products, or others. academic templates are usually mandated by administrators without a full understanding of the specific content and uses of the library web site. many problems can occur when trying to fit an existing library web site into a poorly designed academic template. it can be very difficult to modify the template effectively for the library’s purposes. an example of one specific problem is confusing links on the template, where a link on every page to the “university catalog” links to the course catalog and not the library catalog, which is very confusing for users. another example is a search box as part of the academic template—what are users searching? the university web site? the library web site? the library catalog? the world wide web? another drawback to using academic templates for library web sites can be the time involved in training librarians, staff, and library web site administrators. the existing academic web site design and academic templates | peterson 219 content must be fit into the new template—a huge project, given that many library web sites contain one thousand pages or more. generally, a decision to use a template is accompanied by a decision to use a cms or new web-page editor. this takes yet more time to train individuals on the new software in addition to the new template. ■ benefits of using academic templates one of the benefits for libraries using an academic template is the ability to exploit the expertise of the web site designers who created the template. the academic template often incorporates images, logos, and branding that the library may not be able to design otherwise. many libraries do not have professional web designers on staff; even if they do, there often is no one person who designs and maintains the entire library web site. instead, different parts of a library web site are designed and maintained by different individuals with varying degrees of web site ability. as a result, many library web sites are a mix of styles, which can be disorienting for students who are familiar with the university’s “look.” web site uniformity has a positive effect on usability since familiarity with one part of the web site helps students, faculty, table 1. percentages of occurrences of academic templates no academic template

libraries | december 2006 and staff navigate other parts of the web site. even web site basics such as knowing the color and style of the links and how to navigate to different pages can be helpful.8 another benefit is academic templates are generally ada compliant as required under section 508 of the rehabilitation act of 1973.9 as usability and usability testing become more prevalent, academic template designers may also test the template and navigation for usability. such testing will improve the template and thus the library web site as well. ■ trends in academic and library web sites colleges and universities are responding to a new generation of students, the majority of whom have grown up with computers. in trying to meet their needs and desires, many academic web sites have high-quality photographs, quotes, and testimonials from the universities’ students on their home pages. more and more materials are being placed online to allow both prospective and current students to do what they need to do twenty-four hours a day, from registering for classes to handing in research papers. many web sites have interactive elements such as instant polls or quizzlets or use instant messaging to connect with tech-savvy students. for example, prospective students can chat with admissions staff members or current students about what it is like to attend a particular university. a large number of sites also highlight weblogs written by current students or those studying abroad. these features allow students to use the technology they are comfortable with to maximize their academic experience. numerous library web sites are changing as well, featuring a library catalog, article database, or federated search box on the home page to allow users to search instantly. additionally, library sites are beginning to include images of students using the library, external or internal shots of the building, flash graphics, icons, and sound. many incorporate screen captures to help users navigate specific databases or forms. in addition, an increasing number of libraries use weblogs to give more of a dynamic quality with daily library news and announcements. ■ strategies for using academic templates based on comments received in april 2005 during the poster session, and in recent electronic discussion list postings, many academic libraries are dealing with these issues. libraries should work on creating a mission statement and objectives for their web sites that expand upon the library’s mission, the institutional web site’s mission, and the institution’s overall mission and brand. librarians must be knowledgeable about web site usability and trends in web site design in order to communicate effectively to designers and administrators. librarians should also become members of campus web committees and be a voice for library users during the design process. teaching administrators and campus web designers about the library and the library web site’s prominence are important tools to successfully deal with any proposed university-wide academic templates. for example, a librarian could mock-up a few pages, conduct informal usability testing, and invite administrators to learn firsthand about potential problems library users could experience with a template. librarians could also propose a modified template that uses a few key elements from the academic template. this would maintain the brand but retain enough space for important library content. connecting with other librarians and learning from each other’s successes and failures will also help bring insight into this academic template issue. ■ conclusion the use of academic templates is only going to increase as institutional web sites grow in complexity and importance. libraries are an important part of institutions both physically—on campus—and virtually—as part of the campus web site. academic templates are part of a unified design scheme for colleges and universities. librarians must work with both library and university administrators to create a well-designed but usable library web site. they must advocate for library users and continue to help students and faculty access the rich resources and services available from the library. library administrators need to allocate resources and staff time to improve their web sites and to work in concert with academic web site designers to merge the best of the academic template to the best of the library site while not sacrificing users’ needs. the result will be highly used, highly usable library web sites that attract students and keep them coming back to access the fantastic world of information available in today’s academic libraries. ■ references 1. robert sevier,

library automation has been the appearance of commercial ventures established to provide for an effective use of the new ideas and techniques of automation and related fields. some of these ventures have offered the latest in information science research and development techniques, such as systems analysis, management planning, and operations research. others have offered services based on new procedures, for example, computer-produced book catalogs, selective dissemination of information services, indexing and abstracting activities, mechanized acquisitions, and catalog card production systems. one innovation is a new technique devised for libraries to reduce the clerical effort required to prepare materials for binding and to maintain the necessary related records. the technique is called help, the heckman electronic library program. it was developed by the heckman bindery of north manchester, indiana, with the cooperation of the purdue university libraries. it was recognized by heckman's management that the processing of 10,000 to 20,000 periodicals weekly and the maintenance of over 250,000 binding patterns would soon become too unwieldy and costly unless more efficient procedures were developed. it was additionally realized that any new system should also be designed as a means to aid libraries with their interminable record-keeping problems. the latter purpose could be accomplished by providing a library with detailed and accurate information regarding each periodical it binds, and by simplifying the library's method of preparing binding slips for the bindery. in the fall of 1969, after a detailed analysis, the heckman bindery management began the development and programming of a computerized binding pattern system. this system was a result of a team effort involving management, sales, and production departments. john pilkington, data processing manager, directed the installation of the system and earl beal performed the necessary programming functions. in december of 1971 approx imately 700 libraries were using the system, and about 100,000 binding patterns were in the data file . 138 journal of library automation vol. 5/2 june, 1972 as the system was developed, a library's binding pattern data were converted to machine-readable form which then made it possible for the bindery automatically to provide nearly complete binding slips for each periodical title bound. in addition, the system provides an up-to-date pattern record for the libraries' files, and the bindery maintains the resultant data bank of pattern records as the library notifies it of additions, changes, and deletions. in this manner, the bindery expects to establish an efficient method for purging the file of out-of-date information. the system revolves around four forms: the binding pattern index card, the binding slip, the variable posting sheet, and the binding historical record. the binding pattern index card (figure 1) is a 5" x 8w' card, pink in color, which is a computer printout. one of these cards is retained in the library as its pattern record for each set of each periodical bound by the library. the data given on the card are essentially the same as those maintained by most libraries in their manual pattern £les, except that more detail is provided by the help system, and the library does not maintain the record-the bindery does-in machine-readable form. as changes are made to the patterns, the library clerk simply crosses out the old data on the appropriate binding slip and writes in the new data. when the bindery receives the binding slip, a new index card is produced, among other records, and forwarded to the library with the returned shipment of bound volumes. the system also provides for one-time changes that do not affect the pattern record. the data contained on the index cards include the library account number, the library branch or department code, the pattern number, color, type size, stamping position, title (vertical or horizontal spine positions), labels, call number, library imprint, and collating instructions. the collating instructions, which are listed in the instruction manual provided by the bindery, are given as a series of numeric codes. asterisks are used to indicate the end of a print line. the binding slips are also 5" x 8}2'' forms, but they are four-part multiple forms, of which three parts are sent to the bindery with the periodical to be bound, and one part, a card form, is retained by the library as its "at bindery" record. the information required by the binding slip is essentially the same as that included on the index card. the library, however, must provide the variable data such as volume number(s), date(s), month(s), or whatever information is required to identify a specific volume. the variable posting sheet (figure 2) is an 8)~" x 11" form that is used by the library when it sends several volumes or copies of a volume to the bindery at the same time. since the bindery cannot determine beforehand the number of physical volumes of a title a library will want to send for binding at a given time, it sends to the library only one printed-out binding slip to be used for the next volume of a given serial. if multiple volumes of -r-~---------------------------------------------:r-0 pattern cust. acct . no. i lib rar y' i

in the system is for heckman's internal operations. that is a data input form known as the "pattern printing setup" (figure 5). this form is used by the bindery's input clerks to prepare new binding patterns for conversion to machine-readable form. the data prescribed by the form is much like that required by the binding pattern index card, except that data tags are shown for keypunching purposes. the system operates on an ibm system 3 computer with two 5445 disk drives and a 1403nl printer. the disk drives provide a total of 40,000,000 characters of on-line storage in addition to the 7,500,000 usable characters provided by the system 3 itself. five 5496 data recorders are used for data conversion. the programs are written in rpg2. the development of computer-oriented commercial services for libraries suggests that, perhaps if librarians wait long enough, they will not have to automate their libraries as commercial ventures will do it for them. the rapid appearance of systems-analysis firms, commercial and societal abstracting and indexing services, management and planning consulting groups, and data processing service bureaus tends to bear this theory out. at the very least, libraries will not be able to automate internally without providing for the incorporation of such ready services into their systems. when a service such as help is made available at no additional charge, there is no way for libraries to avoid automation. donald p. hammer donald p. hammer is associate director for library and information systems, university of massachusetts library,

utilizing nuclear knowledge taxonomy an approach using text mining faizhal arif santosa information technology and libraries | march 2023 https://doi.org/10.6017/ital.v42i1.15603 faizhal arif santosa (faizhalarif@gmail.com) is academic librarian, polytechnic institute of nuclear technology, national research and innovation agency. © 2022. abstract the national nuclear energy agency of indonesia (batan) taxonomy is a nuclear competence field organized into six categories. the polytechnic institute of nuclear technology, as an institution of nuclear education, faces a challenge in organizing student publications according to the fields in the batan taxonomy, especially in the library. the goal of this research is to determine the most efficient automatic document classification model using text mining to categorize student final project documents in indonesian and monitor the development of the nuclear field in each category. the knn algorithm is used to classify documents and identify the best model by comparing cosine similarity, correlation similarity, and dice similarity, along with vector creation binary term occurrence and tf-idf. a total of 99 documents labeled as reference data were obtained from the batan repository, and 536 unlabeled final project documents were prepared for prediction. in this study, several text mining approaches such as stem, stop words filter, n-grams, and filter by length were utilized. the number of k is 4, with cosine-binary being the best model with an accuracy value of 97 percent, and knn works optimally when working with binary term occurrence in indonesian language documents when compared to tf-idf. engineering of nuclear devices and facilities is the most popular field among students, while management is the least preferred. however, isotopes and radiation are the most prominent fields in nuclear technochemistry. text mining can assist librarians in grouping documents based on specific criteria. there is also the possibility of observing the evolution of each existing category based on the increase of documents and the application of similar methods in various circumstances. because of the curriculum and courses given, the growth of each discipline of nuclear science in the study program is different and varied. introduction the national nuclear energy agency of indonesia (batan), now known as the research organization for nuclear energy (ortn)—national research and innovation agency (brin), in 2018 issued a decision regarding batan’s six competencies: isotopes and radiation (ir), nuclear fuel cycle and advanced materials (nfcam), engineering of nuclear devices and facilities (endf), nuclear reactor (nr), nuclear and radiation safety and security (nrss), and management (mgt). these areas of focus are also known as batan’s knowledge taxonomy, which is used to support nuclear knowledge management (nkm) and the grouping of explicit knowledge in repositories.1 the polytechnic institute of nuclear technology (pint), which is under the auspices of batan and is now in one of the directorates of brin, can also utilize batan’s knowledge taxonomy to classify students’ final assignments. every year the pint library accepts final assignments from mailto:faizhalarif@gmail.com information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 2 santosa students who have graduated from three study programs, namely nuclear technochemistry, electronics instrumentation, and electromechanics. over the past six years (2017 to 2022), 563 final assignments in indonesian were collected and needed to be classified into the batan’s knowledge taxonomy in order to see the document growth of each existing competency. however, it is quite time consuming for librarians to assign individual documents to the most appropriate taxonomy term. it is also possible to involve experts to determine the right group, which results in increased working time to complete a document. this obstacle arises because librarians do not have in-depth and detailed knowledge of the nuclear field so it is feared that grouping errors will occur. in this study, the author tried to classify the collection of final project documents owned by the pint library based on batan’s knowledge taxonomy. the author used text mining tools, choosing the k-nearest neighbors (knn) algorithm for this study. similar research also leads to trying to focus on automatic document classification of certain subjects,2 which in this case is the subject of nuclear engineering. the hope is that users will find it easier to explore knowledge according to their area of interest through taxonomy grouping based on explicit knowledge,3 in this case, pint students’ final project documents. finding the trend of research conducted by students on each subject is also one of the goals of this research. literature review text mining in libraries the increasing number of publications currently makes it a challenge to classify and find out the growth and trends of a topic. document classification is one of the jobs that is quite time consuming so document classification automation by utilizing text mining is very necessary.4 the application and utilization of text mining itself is very broad. several studies have demonstrated the usefulness of text mining in libraries. pong et al. from city university of hong kong conducted research to facilitate the classification process using machine learning.5 this study aimed to streamline document categorization utilizing automatic document classification by using a system called the web-based automatic document classification system (wadcs) and claimed to be the pioneer of a comprehensive study of automatic document classification on a classification that is already popular in the world, namely the library of congress classification (lcc) utilizing knn and naive bayes (nb). this research indicates that the machine-learning algorithm they used can be applied by the library for document classification. wagstaff and liu utilized text mining to perform automatic classification to help make decisions to select candidate documents for weeding.6 this study used data from wesleyan university from 2011 to 2014 to predict which documents were eligible for weeding and which will be stored. five classifier models, namely knn, naive bayes, decision tree, random forest, and support vector machines (svm), were used to compare their performance. while this process may not replace librarians, this study can help librarians make better decisions and reduce their workload significantly. lamba and madhusudhan applied the use of text mining to extract important topics which were published in the desidoc journal of library and information technology over a period of 38 years.7 the latent dirichlet allocation (lda) method used in this study is able to find topics from information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 3 santosa within a collection of documents so that they can see how these topics develop over time. because lda is an algorithm for looking at topics from a group of words that appear together, the authors suggest that this study be expanded by utilizing articles that have been labeled using supervised classification. knn classifier various studies try to find answers to the most appropriate method of grouping the collection of documents. the knn and svm algorithms were used as comparative methods in the document classification study.8 however, there is no definite standard for the methods used in text mining.9 choosing the right technique in each phase of document classification can improve the performance of the text classifier, so, experts generally make adjustments to existing methods to get better results.10 kim and choi compared knn, maximum entropy model (mem), and svm to classify japanese patent documents by focusing on the structure of patents.11 instead of comparing the entire text, specific components named semantic elements, such as purpose, background, and application fields, are compared from the training document. these semantically grouped components are the basis for patent categorization. in addition, the strategy used is the existence of cross -references from two semantic fields that are useful for determining the intentions of the patent writer s who are still unsure or hidden. this strategy works well on knn compared to mem and svm where svm doesn’t do very well when handling large data sets. however, research conducted by alhaj et al. on arabic documents showed that svm can outperform knn by implementing a stemming strategy.12 meanwhile, through the approach to the relationship between unstructured text documents, the study conducted by mona et al. was able to increase the performance of knn combined with tf-idf by 5 percent.13 the knn algorithm is one of the popular classifiers that categorizes new data based on the concept of similarity from the amount of data (determined by the specified “k” value) around it.14 this method is believed to be able to group documents effectively because it is not limited to the number of vector sizes.15 wagstaff and liu noted that one of the weaknesses of knn is the long processing time when faced with large datasets, but knn as a classifier is easy to apply.16 in terms of measurement, previous experiments showed that knn was not suitable when used with euclidean distance.17 generally, similarity measures such as cosine, jaccard, and dice were used in the knn classifier.18 one of the problems in text classification is the number of attributes or dimensions so that many irrelevant attributes in the data set cause the classifier’s performance to not run optimally.19 for this reason, it is necessary to have a technique to increase effectiveness and reduce dimensions that are too large through the selection of features or terms,20 such as within-document tf, weighting with one of the popular methods, namely tf-idf (which sees how important a word is in a collection of corpus),21 and binary representation which looks at the absence and presence of a concept in a document22 by converting it to 0 and 1.23 aims of the study university libraries have a vital role in managing internal publications to support the education ecosystem. in connection with the role of the pint to support nkm and nuclear development, it is necessary to apply technology to help provide advice on certain classes of documents. in addition, in order to see scientific developments, generally experts conduct bibliometric studies which are information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 4 santosa limited to the title and abstract fields. text mining provides an opportunity to dig deeper. instead of just the title and abstract, this study used the full text of the final project collection. the trend of a subject will be seen from the growth and percentage of existing documents. so, the objectives of this study are to • explore the best knn model to be applied to classify the final project; • know the development of nuclear subjects based on batan’s knowledge taxonomy; and • know the development of nuclear subjects from each study program at the pint. methods a total of 99 documents were taken from the batan repository and manually labeled as reference data. this study was conducted using rapidminer studio software. the first document processing method is to convert all words into lower case and divide the text into a collection of tokens. filters on tokens are also applied based on the length of the token. in this case, the author applied a minimum of 3 characters and a maximum of 25 characters. stop words were also applied to eliminate short words (e.g., “and,” “the,” and “are”), thereby reducing the vector size. english and indonesian stop words were used for this study to overcome the use of english in the abstract section and indonesian as the document language. the collection of words from haryalesmana was chosen to be the stop words for indonesian.24 the stemming technique is applied to reduce dimensions that are useful for improving the function of the classification system 25 by changing word forms into basic word,26 e.g., water, waters, watered, and watering into water. this analysis applies wicaksana data to indonesian stemming.27 some words cannot be separated from other words because they form a meaning, e.g., nondestructive testing, biological radiation effects, structural chemical analysis, and water -cooled reactors. to overcome this case, the use of n-grams can help identify compound words that have a meaning so that the words are not reduced.28 n-grams will record a number of “n” words that follow the previous word.29 to accommodate these words, in this study, three words were assigned to n-grams. information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 5 santosa figure 1. nuclear taxonomy classification framework. vector creation in this study used tf-idf and binary term occurrence and then compared them to determine the best performance. in the knn method, it is necessary to determine the value of “k” manually, so a value of 2–10 was chosen by activating a weighted vote which is useful for weighing the contributions of neighbors in the vicinity. weight voting indicates the use of multiple voting methods by assigning a weight to each neighbor depending on their distance from the unknown item.30 the types of measurement chosen to get maximum results were numerical measure and tested cosine similarity, correlation similarity, and dice similarity. meanwhile, to measure performance, the author used cross validation with a number of folds of 10. then, using this set of procedures, documents from the batan repository are classified. the procedure that achieves the highest level of accuracy is then submitted as a model. this model was applied to 563 final project documents that have not been labeled so that each document has a label according to batan’s knowledge taxonomy. results the experiment was carried out 54 times to determine the best knn performance from the proposed approach, namely cosine-binary, correlation-binary, dice-binary, cosine–tf-idf, correlation–tf-idf, and dice–tf-idf utilizing cross validation. cosine was still the most accurate in the tf-idf vector creation process, with an accuracy of 81.89 percent on seven neighbors, and dice reaches the lowest point when used on four neighbors. in contrast to correlation and dice, cosine can perform well when creating binary vectors. cosine on four neighbors had the best performance, with a 97 percent accuracy rate. the lowest accuracy occurred when the number of selected neighbors was two and the overall numerical measure had decreased in neighbors more than nine. the classification model for unlabeled documents was determined to be the cosine-binary method with four neighbors. the experiment found that this method did not successfully group three information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 6 santosa documents (for details of the confusion matrix, see appendix a). even though document 7 ought to be on nfcam, but with a lower score of 0.49921, it was predicted on the nrss with a confidence value of 0.50079. documents 86 and 93, which were supposed to be about endf, were unable to be foreseen. document 93 was predicted on the nrss with a confidence value of 0.50126 and document 86 was predicted on the nr with a value of 0.49936. figure 2. a comparison of the accuracy levels in the knn method. this study utilized 563 unlabeled documents that were divided into six years. there were 34 fewer documents in 2021 than there were in 2020, a significant drop from the previous year (see table 1). the number of documents then climbed again in 2022, reaching 98. rapidminer’s labeling process ran into issues when it got to the process document stage. to improve memory performance, the documents were split into three runs (2017–2018, 2019–2020, and 2021–2022) because the memory was not sufficient to execute a set of commands on docu ment processing. the results of the previous set of procedures were then exported as tabular data for further study. every year, the evolution of each nuclear subject can be seen in the final project report (see fig. 3). during the test period, 282 documents (50.09%) of the total extant papers had an endf study, followed by ir with 95 documents (16.87%) and nfcam with 69 documents (12.26%). while there were very little changes between nr and nrss, nr contains 47 papers (8.35%) connected while nrss had 45 documents (7.99%). mgt was the subject with the fewest documents, with a total of 25 (4.44%) from 2017 to 2022. information technology and libraries march 2023 exploring final project trends

report on instrumentation electronics, which included 187 papers, was successfully predicted into five subjects. endf was projected to contain 141 documents (75.40%), nrss was likely to contain 24 documents (12.83%), and nr was predicted to contain 14 documents (7.49%). furthermore, only 7 documents (3.74%) on mgt and 1 document (0.53%) on ir were predicted. nfcam, on the other hand, is not mentioned in any of the electronics instrumentation publications (see fig. 5). final processing was performed on a collection of nuclear technochemistry documents. one hundred sixty-four documents are predicted at ir of 53.66 percent (88 documents), nfcam of 18.90 percent (31 documents), nr of 13.41 percent (22 documents), mgt of 9.15 percent (15 documents), endf of 3.66 percent (6 documents), and the remaining 1.22 percent (2 documents) were predicted on the nrss. subjects that were popular each year vary (see fig. 6) when compared to electromechanics and instrumentation electronics, where endf was the most popular topic in these two study programs. information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 9 santosa figure 5.

santosa figure 6. nuclear subject development in nuclear technochemistry by % each year. discussion the study found that implementing knn with cosine similarity in association with vector construction=binary and k=4 resulted in the highest accuracy results of 97 percent. in general, this strategy outperformed in every class examined, and it can only be balanced on one occasion, notably at k=9 by utilizing correlation similarity. when compared to the use of tf-idf, the results likewise indicated that binary term occurrence always functioned well. tf-idf was only able to achieve its highest accuracy of 81.89 percent when k was 7 using correlation similarity. cosine similarity also seemed to work efficiently on every vector creation, both when using binary and tf-idf (in classes numbering 2, 5, and 10 the use of tf-idf was not optimal), compared to numerical measures of correlation similarity and dice similarity. cosine similarity evaluates the similarity of documents, and a high similarity score indicates that the documents are quite similar.31 nuclear field growth in general, aside from the endf field, which is steady and increasing, other subjects endure annual changes in development. for the past six years, endf has been the most popular subject among students. the endf reached the highest percentage rate in 2022, with 59 documents predicted on this subject. students preferred engineering final project reports on mechanics and structures, electromechanics, control systems, nuclear instrumentation, or nuclear facility process technology. research conducted by wang et al. also suggests that the current popular topic of research on nuclear power is modeling and simulation.32 information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 11 santosa the endf document’s average confidence value was 0.6499916, with a median value of 0.7490455. the two documents with the lowest confidence in the endf were document numbers 233 and 597. document 233 had a confidence value of 0.25105 and was predicted in the other three subject areas (nrss, nr, mgt) with close values. likewise, the 597 documents predicted in the endf with a confidence value of 0.25156 were higher than the nrss, nfcam, and ir subjects, but with a not too significant difference. both of these documents can be investigated further and directly evaluated by the librarian in order to obtain a more precise field. the majority of the final project reports projected in the endf have confidence levels around 0.50, and some even higher at 0.75. this study also reveals that 11 documents in the endf category have a confidence value of 1. with lower nrss confidence values, 239 endf documents connected to the nrss field. this relationship demonstrates a good tendency among students conducting nuclear engineering related to the nrss discipline. though it differs significantly from endf, ir is becoming a prominent field. the final project report for ir was developed in 2017–2018, but it shrank again from 2019 to 2021, then increased in 2022. in comparison to other fields, ir has the highest minimal confidence score of 0.4 987, with many documents lying within the 0.5 and 0.75 range. meanwhile, the confidence value for 26 documents predicted by ir is 1. the nfcam subject area is a prediction that appears frequently in ir predictions but has a lower level of confidence. there are 54 documents indicating the existence of research that involves isotopes and radiation in nuclear materials, nuclear excavations, radioactive waste, structures, or advanced materials. nfcam is inversely proportional to the conditions that occur in endf. after increasing in 2019, this subject faced a reversal over the next three years, with only two documents classified in this subject through 2022. students are still uncommonly interested in nuclear minerals, nuclear fuel, radioactive waste, structural materials, and advanced materials. six projected documents in this field have confidence levels of 1, while many more have confidence levels between 0.50 and 0.75. the ir field is also expected to appear alongside the nfcam field publications. there were also ups and downs in nr and nrss. twenty-five of the 47 documents identified on the nr were also predicted with a lower value in the nrss field. this demonstrates that students explored the relationship between the subject of reactor research and safety and security in various documents. meanwhile, only eight of the 46 nrss papers are unrelated to the endf field. this demonstrates that students who study nuclear safety and security tend to perform engineering to address situations involving nuclear safety and security. documents in these two fields are usually concentrated in the 0.5 confidence value range in both nr and nrss. mgt is one of the least studied topics among students. human resources, organization, management, program planning, auditing, quality systems, informatics utilization, or cooperation are more commonly associated with the mgt field. the mgt increased in 2020, although it became the field with the fewest documents on earlier occasions (2017 to 2019 and 2021 to 2022). in terms of confidence value, 21 mgt documents have a value greater than 0.5, with eight documents worth 1. with 10 documents, the endf is the most often discussed study area with mgt. progression in each study program even if they are still within the purview of nuclear science, the growth of the nuclear field in each study program differs depending on the curriculum. students are influenced by knowledge, and information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 12 santosa more specifically the process of learning and comprehending (whether theoretical or more practical).33 endf is still the most popular field in electromechanics and electronics instrumentation study programs. these two study programs offer courses in endf topic areas such as mechanical, civil and architectural, electromechanical, electrical, control systems, and radiation detection for nuclear devices. furthermore, the electronics instrumentation study program offers courses on nuclear electronics, signal processing techniques, and practical work on interface and data acquisition techniques, all of which are part of the endf nuclear instrumentation group. apart from endf, the fields of nfcam and nrss have been present in electromechanics for a period of six years. while mgt is currently a less appealing topic, there have been no final project reports relating to mgt in the most recent three years. in electronics instrumentation, the absence of a field occurs in nfcam. the findings of the predictions demonstrate that none of the documents predicted on nfcam were proper. meanwhile, only 10 documents that intersect with nfcam which have lower confidence in the range of values from 0.247 to 0.251. nuclear minerals, nuclear fuel, structural materials and advanced materials, and radioactive waste were not studied in depth in this study program, illustrating why nfcam is not predicted in instrumentation electronics. in contrast to other study programs, ir is the most predictable field in the final project report in nuclear technochemistry. in this investigation, nuclear technochemistry owns 88 of the 95 documents examined. this study program includes ir specializations such as the use of isotopes and radiation in agriculture, health, and industry. radioisotope production becomes another discipline that specializes in the creation of isotopes and radiation sources, which explains why ir is so popular among nuclear technochemistry students. the nfcam field was not present in 2022, despite the fact that it had been the topic of several students’ studies throughout the preceding five years. while the endf and mgt fields have only been present in the last three years, there were no predictable papers in the previous three years. conclusion the trend of research activities carried out by students from one study program to the next appears to vary although they are both within the scope of the nuclear field. for example, the field of endf is quite popular among electromechanics and electronics instrumentation students but not for nuclear technochemistry students because endf only appeared three years ago and the number of documents is still modest. however, endf deserves to be a field that needs attention. nuclear technochemistry students with radiochemistry learning experiences demonstrate that the ir field is linear and interesting to them. due to a paucity of publications, the low proportion in certain categories, e.g., mgt, shows a potential to further investigate this field. this study demonstrates an opportunity to use text mining to assist librarians in performing automatic document classification based on specific subjects. the best model in this study is produced by combining knn with cosine similarity and binary term occurrence. the model used can help improve the quality of decisions made to accurately and efficiently categorize documents. to determine a more specific classification, pay close attention to documents that have a low level of confidence and intersect with other issues. this study is limited to the knn method and information technology and libraries march 2023 exploring final project trends utilizing nuclear knowledge taxonomy 13 santosa documents from the batan repository, as well as final project documents for pint students. large-scale testing can be conducted, for instance, in the international atomic energy agency ’s (iaea) nuclear repository known as the international nuclear information system (inis) repository, or in other databases with the complexity of categorizing documents throughout many languages. data accessibility datasets and

endnotes are pdf documents accessible? | ribera turró 25 are pdf documents accessible? mireia ribera turró adobe pdf is one of the most widely used formats in scientific communications and in administrative documents. in its latest versions it has incorporated structural tags and improvements that increase its level of accessibility. this article reviews the concept of accessibility in the reading of digital documents and evaluates the accessibility of pdf according to the most widely established standards. in a world in which an increasing amount of informa-tion is circulating in digital format, document acces-sibility is becoming a major concern. many countries have adopted legislative measures concerning digital accessibility (see, for example, the web accessibility initiative at www.w3.org/wai/policy) and the guru of the web, jakob nielsen, has included it in several columns (nielsen 1996, 1999) and reports (coyne and nielsen 2001a, 2001b, 2001c; schade and neilsen 2002). improving document accessibility for disabled persons, including the elderly, offers good business opportunities for it firms. for example, sun has introduced strict accessibility guidelines in its java programming language, and microsoft has incorporated an increasing number of assistive technologies in its operating system. for its part, adobe came out clearly in favor of accessibility in the latest updates of its flagship format, pdf, and its free reader program (adobe 2005). the efforts of these and many other companies are necessary if persons with disabilities are to be able to use products as well as persons without disabilities. in an effect similar to that of the cascade of interactions that takes place in the search for information in a digital library (bates 2002), the accessibility of a digital product is contextual and depends on many layers: the product itself, the application used to operate it, the support of the operating system, and the additional assistive technologies used to transform the content (henry 2007). for example, an html document is considered to be accessible if it complies with the web content accessibility guidelines (wcag 1.0) (w3c 1999, w3c 2006), but it is only usable if the browser with which it is consulted provides the options of accessibility (e.g., by allowing users to modify the associated style sheet), if the user has the necessary assistive technologies—screen magnifiers, screen readers, alternate pointing devices, etc.—to use the information and functionality contained in the document, and if all these tools interact correctly with each other. this article focuses on the accessibility of the pdf due to its importance in the world of digital publishing. though we do not have global statistics on its use, a google search specifying pdf as the format returns 236 million documents, whereas none of the other recoverable formats reaches 50 million documents (postscript 10 million, microsoft word 37 million, microsoft excel 14 million, microsoft powerpoint 14 million). (the search was performed on april 14, 2007, with the arguments filetype:pdf, etc. values were rounded off to the nearest million.) it should be remembered that pdf is the main format used for digital publishing of electronic journals and for a great variety of administrative documents, including e-government communications. furthermore, the subformat pdf/a for archiving is the preferred format for digital preservation in many large libraries, including the library of congress, which recommends it for textual documents in which the appearance is more relevant than the structure (library of congress 2005). finally, according to a study by forrester research in 2005, pdf/a and xml will be the dominant formats in document archiving in 2008 (markham 2005). if our digital memory is going to be in pdf, we must ensure that it is accessible to all persons. so far, the many studies that have been carried out on the accessibility of digital information have considered mainly the accessibility of web content in html. digital documents in a broad sense have never been evaluated from an accessibility viewpoint, and the only user studies carried out on them have dealt with usability—without paying particular attention to special capacities (see dillon 2004)—or user preferences with regard to articles in electronic format (tenopir 2003). because it is a very new field, few studies have concentrated on pdf accessibility, and they do not form part of the scientific literature. however, joe clark and duff johnson have published some interesting articles on the subject (see clark 2005, johnson 2006, 2007a, and 2007b). n what does accessible really mean? the most widespread view of digital accessibility is the regulatory one. the concept of accessibility of digital information was mainly disseminated with the publication of wcag 1.0 by the world wide web consortium (w3c) as the de facto standard in this area, and with its incorporation in the federal legislation of the united states. in the united states, compliance with the accessibility guidelines has been used as a requirement in calls for tenders, and in some cases bidders have been taken to court for failure to comply. from this viewpoint, an accessible application is one that is “valid,” i.e., approved by the criteria of wcag 1.0 or section 508 of the rehabilitation act (u.s. access board) and complymireia ribera turró (ribera@ub.edu) is professor at universitat de barcelona department of library and information science. 26 information technology and libraries | september 2008 ing with their established checklist (see appendixes for the detailed checklist). products must be certifiable as accessible. to facilitate the administrative procedures for approving bids, there is great interest in the creation of automatic protocols for checking compliance. examples of this are products such as the historic bobby, the lift extension for adobe dreamweaver, and the new wcag 2.0, which is still being revised at the time of submission of this manuscript. some authors have evaluated digital journals and database interfaces according to their compliance with these guidelines (e.g., coonin 2002; stewart, narendra, and schmetzke 2005). see the importance of the concept “programmatically determined” in the draft version of wcag 2.0 (w3c 2006). the international standard defined by iso 16071:2003 offers a different definition of accessibility. it considers accessibility to be “the usability of a product, service, environment, or facility by people with the widest range of capabilities” (iso 16071:2003). in other words, accessibility is considered equivalent to usability, with the sole difference that the objective users are not specified but rather defined broadly as having “the widest range of capabilities.” if we consult the standard definition of usability (iso 9241-11:1998), we can rewrite the definition of accessibility as “the extent to which a product can be used (by users with the widest range of capabilities) to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use.” accessibility must also be measured according to the parameters of efficacy, efficiency, and satisfaction for the type of user (hornbaek 2006). furthermore, one should not consider the accessibility of a product in general, but rather in a given context and for given tasks. according to this definition, it would not be appropriate to state that “the website of the company company.com is accessible.” we should state that “the website of the company company.com is accessible for broadband connections in office environments with the browsers internet explorer 6.0 or later and mozilla firefox 7 or later, and for commercial transactions.” a new concept, the “baseline,” appears is wcag 2.0. it marks a great change in the philosophy of website accessibility. the baseline defines the context of the software platform, and the accessibility can be evaluated only in this context. specifying the context is particularly important because some authors have seen a parallel between disabled users and disabling situations, which arise increasingly with the new paradigm of ubiquitous computation (newell 1995). for example, a person suffering from deafness may have the same problems of access as a user in a noisy environment (a discotheque) or one in which silence is compulsory (a hospital or library). accessibility is also linked to computer manipulability. according to the mvc (model-view-controller) pattern, the final format or document should allow its content, its presentation, and its interactivity to be manipulated independently in order to personalize each one according to the user’s preferences. for example, a webpage (content) should be navigable with a keyboard and with a mouse (control), and should be viewable with different font sizes, color contrasts, etc. (presentation). the separation of presentation and content, for example, through cascading style sheets (css), is thus highly desirable. however, there are also other aspects of digital formats related to computer manipulability. for example, it is considered that an open format is more accessible than a proprietary format because it is easier to develop assistive technologies to take advantage of its potential; a multiplatform format is more accessible than a format linked to a particular platform because it is adapted to a greater diversity of controls; a format that includes characteristics of internationalization is more accessible than one that does not because it can present a greater wealth of content; and a format that uses semantic encoding is more accessible than one that uses syntactic encoding because the software tools can extract more information from it. finally, several authors in the field of publishing (dechilly 2004) and the field of accessible design (paciello 2000, petrie and weber 2002) have related the accessibility of the digital documents to the structuring of the content and its potential transformation. specifically, raman (1994) defines the accessibility of a digital document as n the amount of structural information captured by the encoding; n the degree to which this structural information is available for processing by other applications; and n the availability of the appropriate software needed to process this structure. n disabilities that affect reading and assistive technologies returning to the definition of accessibility as being for the widest range of capabilities, it is observed that some disabilities have direct effects on digital reading and associated activities (o’hara 1996), and that there are some well-established assistive technologies that can eliminate or minimize these effects. there are three main groups of print disabilities that also affect the comprehension of graphics: n all degrees of vision problems, from total blindness to reduced vision, color-blindness, and other dysfunctions. the most widely used assistive technology for total blindness is that of screen readers, which digest the information on the screen and transform it into spoken text. reduced vision makes it difficult to read or capture the information offered; for persons with this disability, screen are pdf documents accessible? | ribera turró 27 magnifiers offer an optical zoom of the information shown in addition to color and contrast adjustment. in both cases additional information in the document is often required, such as explanatory subtitles for video recordings and alternative descriptions for images. n motor skill problems, particularly those affecting the upper extremities. this disability hinders the interaction with information and the activation of controls, links, and even linear scrolling in the document. there are a great variety of assistive technologies for persons with this disability, including pointing devices, alternative keyboards, voice synthesis technologies for activating controls, and even assistive technologies for automatic text completion. n different types of cognitive problems that affect reading comprehension. those caused by dyslexia or early deafness can benefit from screen magnifiers, screen readers, and automatic text completion. those caused by cognitive disabilities—which have not been widely studied—often require a simplified presentation of the information through graphics or very simple language. n pdf pdf is the descendent of postscript and is oriented toward presentation. though recent research has experimented with new, more versatile image models (bagley, brailsford, and hardy 2003), these have not yet been incorporated in the commercial format, which is still basically postscript. pdf is a format of digital dissemination that has replicated paper documents for many years. its faithful reproduction and portability on different platforms, in addition to a commercial policy of free dissemination of the reader program, have given it a dominant market position among digital publishing formats. in the latest versions, pdf incorporates functions of digital management of access rights (drm) and allows information providers to regulate the permission to view, print, extract, and modify the content. the orientation toward presentation, which has turned pdf into the de facto standard in the publishing industry, is its main drawback for accessibility. in order to solve this, from version 1.4 onward adobe has incorporated structural elements in the format (e.g., structural tags). this article therefore only studies the most recent versions of the format. despite the potential of the format, it is possible to create pdf documents of very different qualities. the application from which a pdf document is generated and the process followed in creating it directly affect the accessibility of the resulting document. specifically, pdf can have four increasing levels of accessibility: 1. pdf image—no accessibility 2. pdf text 3. pdf text, with order 4. tagged pdf—maximum accessibility pdf image documents a pdf image document is a document obtained from scanning or photographing a printed document. its content is exclusively the bitmap resulting from the optical process. it does not allow searches in the document or text extraction because the text is only coded as a graphic. a pdf image document is similar to a paper document in its level of accessibility. for blind persons or persons with reading problems (caused by dyslexia or early deafness) it must be transformed through an optical character recognition process in order to encode the text and adapt it to screen readers or alter the presentation. the only advantage that the digital presentation may have over a paper presentation is the possibility of optical zooming and increasing the text size to benefit persons with certain visual impairments. pdf text documents the second level of accessibility is that of pdf text documents, which come from the same source as image files but have gone through an optical character recognition process and incorporate the resulting text in the file. in this case it is possible to search the content, export the content to a word processor, listen to it with screen readers, and perform other types of conversion. specifically, as of version 6 or later, reader incorporates the possibility of removing columns, viewing the text in negative (white on black), increasing the font size, and even hearing it with a screen reader. according to the quality of the ocr used and of the subsequent manual revision, these files often contain slight typographic errors that may affect the results of text searches and also make continued reading more difficult (especially when a screen reader is being used). if the quality of the original is poor, or it is in bad condition, ocr programs often make small mistakes. furthermore, if the original has a creative layout in which the order of presentation does not correspond to the order of reading, the resulting text appears disordered and is therefore illegible; this problem can arise due to such common structures as footnotes, headers, and margin notes. pdf documents with ordered text the third level of accessibility is that of pdf text docu28 information technology and libraries | september 2008 ments in which the correct reading order has been established. this can be done when the document is created or by editing it at a later stage. tagged pdf documents the fourth and highest level of accessibility is when the pdf document contains ordered text and structural tags to define headers, tables, lists, etc. with this encoding, an assistive technology can present a summary of the document, facilitate navigation, provide structural information of the content, etc. this fourth level is normally achieved only by postprocessing a pdf document that has already been created. when documents are converted from the most widely used word processors to pdf, there still arise errors that must be revised manually. for example, when tables are converted from microsoft word to pdf, the tags are created correctly in general, but the headers of the tables are not marked up because word does not allow them to be differentiated structurally. another example is the conversion from open office 2.0, in which the documents created have major structural deficiencies. n are pdf documents accessible? even at the highest level of accessibility, tagged pdf document, the aspects discussed above in the definition of accessibility must be checked. though pdf is totally multimedia, particularly in the latest versions, and it now allows programming to be included, the commonest pdf documents are plain documents in which text and images are reproduced and the interactivity is reduced to the use of forms; these documents will thus be the ones analyzed here in an initial approach to pdf accessibility. though this may represent a limitation, in fact it includes most of the pdf documents used for electronic journals and administrative documents. pdf’s accessibility is analyzed from the viewpoint of the end users, the readers of the document, so comments on the most widespread user agent, reader, are also included. pdf’s compliance with wcag 1.0, the wcag 2.0 draft, and section 508 is evaluated, and its accessibility is considered from the viewpoint of the platforms on which it runs and the programs that can be used to create documents. however, reader and adobe acrobat professional are not evaluated as authoring tools or user agents because that is not the focus of this article. wcag 1.0 in 1997 the w3c officially created an initiative to foster the accessibility of the web (engelen 2001), following the vision of its creator, tim berners lee: “the power of the web is in its universality. access by everyone regardless of disability is an essential aspect.” the web accessibility initiative (wai, www.w3.org/wai) works with organizations around the world to develop strategies, guidelines, and resources to help make the web accessible to people with disabilities. w3c-wai has established three recommendations to improve the accessibility of the web: n wcag 1.0, released in may 1999, based on the trace unified web guidelines (version 8), affecting web content in itself (e.g., an html page) n the authoring tool accessibility guidelines, affecting software used to build websites (e.g., dreamweaver) n the user agents accessibility guidelines (uaag), affecting browsers and multimedia players that interact with web content (e.g., mozilla firefox) of these guidelines, the ones that have had the greatest impact are wcag 1.0, because they affect content providers, such as governments. most legislations promoting digital accessibility have made direct or indirect reference to these guidelines. wcag 1.0 is divided into in fourteen guidelines or general principles of accessible design, which are specified through several checkpoints. each checkpoint has a priority level based on its impact on accessibility. checkpoints of [priority 1] are a basic requirement for some groups to be able to use web documents. the ones of [priority 2] will remove significant barriers to accessing web documents. checkpoints of [priority 3] will improve access to web documents (w3c 1999). wcag 1.0 is designed to evaluate documents, not formats, so in this article the evaluation often refers to the potential of the format if it is used properly to create documents. pdf can potentially comply with all the checkpoints of wcag 1.0 applicable to text, images, and forms (its multimedia potential has not been analyzed in this article) in any priority except for three points: 5.2 headers for tables of complex data, in priority 1. the current version of pdf only foresees the use of th as the header of tables, specifies attributes that allows it to be related to columns or files, but provides no mechanism for grouping cells (like colgroup or rowgroup of html). 3.4 relative units in markup language attribute values and style sheet property values, in priority 2. though the most recent versions of pdf use css, the format only allows absolute values to be specified. however, this does not prevent reader from making extensive zooms of the content of the pdf are pdf documents accessible? | ribera turró 29 documents. 9.5 provide keyboard shortcuts, in priority 3. no mechanism is specified for linking a keyboard shortcut to a content. in both point 4.1, for identifying changes of language, and point 5.1, on simple table headers (both of them in priority 1), although pdf provides for the incorporation of this information, some experiments carried out with the acrobat professional tools for conversion from microsoft word have shown that this information is not correctly transferred from the word processor to the pdf document. for a more detailed analysis, see the tables in appendix a. here we have only commented on the most outstanding aspects. wcag 2.0 draft in the course of time wcag 1.0 has become out of date. the web of 2007 is very different from that of 1999: the increased use of multimedia formats; the growth of webbased software, ajax, the xml subformats; and the paradigm of ubiquitous computing have made it necessary to redefine wcag 1.0 guidelines, which were initially highly focused on html, in order to extend them to all types of format; it has been considered necessary to be able to define an available software platform baseline (for a detailed discussion of the differences between wcag 1.0 and wcag 2.0, see www.webaim.org/stan dards/wai/wcag2.php#differences). however, due to the enormous success of wcag 1.0, the development of the wcag 2.0 has been subject to enormous pressure, and it has received more comments and suggestions than any other guideline of w3c. this is why the process of approval is slower than normal, and though publication dates have been repeatedly announced, the current document is no more than a draft. wcag 2.0 has four principles, each one addressed by several guidelines. under each guideline there are success criteria used to evaluate conformance to this standard for that guideline, which fall into three levels of conformance, each representing a higher level of accessibility (w3c 2006). pdf complies almost absolutely with all the success criteria of all the levels of the four principles of accessibility described in wcag 2.0. only in principle 3 (which establishes that both the content and the controls must be understandable), guideline 3.1, level 3, “make text content readable and understandable” does wcag 2.0 fail in several success criteria: 3.1.3 offer definitions for words used in an unusual way. 3.1.6 offer the pronunciation of words where meaning cannot be determined without pronunciation. in all of these points, the generic title attribute could be used for all the tags, but there is no standard mechanism for differentiating pronunciation or slang. for a more detailed analysis, see the tables in appendix b. here we have only commented on the most outstanding aspects. section 508 of the rehabilitation act in august 2000 the u.s. access board (www.access-board .gov), an independent federal group that oversees the production of guidelines on accessibility for compliance with various legislative measures, published a revised amendment of the rehabilitation act of 1973, stating that the information provided by federal agencies must be accessible to people with disabilities (engelen 2001). as johnson mentions, “the regulations also apply to contractors that submit electronic documents to the federal government”(2007b). compliance with section 508 is parallel to compliance with wcag 1.0. pdf complies with all the points except the ability to associate data cells and header cells for tables that have more than one logical level (checkpoint h). for a detailed analysis see the tables in appendix c. here we have only commented on the most outstanding aspects. n are pdf documents accessible from a computer’s viewpoint? some doubt still remains about whether pdf is an open or closed format. it is a proprietary format, so strictly speaking it is not open, but adobe systematically publishes the specification of format and allows it to be used by third parties free of charge, simply reserving the intellectual property rights (see adobe 2006, 32, for the exact terms of the adobe license). furthermore, adobe recently initiated the process for pdf to become an iso standard (adobe 2007). the latest versions of pdf allow content and presentation to be differentiated. the content consists of the text and images, and the presentation can be encoded like webpages with some properties of css version 1 and 2. the control of the document depends on the program used to read it, since pdf does not allow keyboard shortcuts or alternative actions to be defined for any application. one of its main advantages is that it can be reproduced faithfully on any platform, but in terms of accessibility it is not multiplatform. the structure, links, and forms of adobe reader for assistive technologies are accessed through the microsoft active accessibility technology, so they can only be used on microsoft platforms. the screen reader incorporated as of reader 6 does work on both windows and macintosh. 30 information technology and libraries | september 2008 with regard to internationalization, pdf supports the unicode character set and also allows the language of the document to be specified on a global and local level. though the specification of the format establishes that it supports inverse reading order (e.g., for arabic languages) or vertical reading order (e.g., for asian languages), webaim (webaim 2006) states that it causes problems with them. the structure in a pdf document is transmitted mainly through the tags incorporated in the format since version 1.4. the standard set of tags is fairly limited—more so than that of html 4 (see adobe 2006, sections 10.7 and 10.8, for a complete list). the set of tags can be extended but always with an equivalent with the standard set, which is the only one supported by adobe. the structure is transmitted through the microsoft active accessibility (msaa) technology to any assistive technology, so other applications can also read it. msaa provides agents and synthesizers in several languages that do not tend to be installed by default but can be downloaded free of charge from the microsoft website (www.microsoft .com/msagent/downloads/user.asp). there are currently few programs that can process this structure, of which reader is the most widespread. among the screen readers, jaws by freedomscientific and windows eyes by gw micro can also process pdf files on a structural level. according to joe clark (2005), ibm home page reader and hal screen reader by dolphin can also do so. most of these programs incorporate support for pdf in their latest versions, which are not always the most widely used. n are pdf documents accessible according to the iso standard? on this topic, few studies have been made and much work remains to be done. accessibility should be evaluated for the different types of disabilities that affect electronic reading and for different scenarios and contexts of use. though the tests of users with disabilities are beginning to be generalized, and there are even guidelines on how to do them (coyne and nielsen 2001a), after an extensive bibliographic search i was unable to locate any studies evaluating this aspect in pdf. n the opinion of the experts joe clark, the author of one of the most important books on website accessibility, building accessible websites (2003), currently forms part of adobe’s work group on usability and accessibility. he is one of the greatest proponents of pdf, and claims that it offers some advantages of accessibility/usability compared with html (its greatest competitor for digital documents), such as its ability to use footnotes, notes, and comments. he gives little importance to the fact that it is a proprietary format and argues that the important point is that the specification is public. in his article on the accessibility of pdfs (clark 2005), he defends the use of the format compared with others for certain objectives and needs: for interactive forms, for documents in revision, for design fonts not available in html, as a format of preservation, and for documents that require the management of digital rights. with regard to software, he makes a great defense of reader for taking advantage of documents and resolving problems of accessibility, but recognizes that in the field of authoring tools more programs are necessary. webaim, an initiative for accessibility at utah state university, gives its opinion on some points that facilitate or hinder the accessibility of pdfs: n the screen-reading function only exists in the complete version of reader, and by no means offers the same functionality as jaws or windows eyes. furthermore, to use it one must memorize new access keys that are not common to other programs. n the reflowing function is very useful for persons who require magnification or who work with small screens because it eliminates the horizontal scroll. n webaim recommends the use of html for tables, particularly if they are complex, because current screen readers can process them far better than if they are in pdf. n webaim criticizes the fact that the options for configuring accessibility in reader are highly oriented toward screen readers and magnifiers, and that they are only partial and confusing. for example, it mentions the fact that it is possible to configure some multimedia options but not from the accessibility setup wizard. (webaim 2006) another aspect that receives constant criticism is the cost of creating accessible pdf documents. though throughout this article the accessibility of pdf has been studied from the viewpoint of the user, the lack of tools for creating documents must also be stressed. though the specification is in theory public and there exist software tools (e.g., the pdflib software library and the xslt transformations in open office) to generate tags in a pdf that are the result of a document conversion, users normally depend on the tools of microsoft office and the acrobat professional program to create accessible pdf documents. even with these tools, editing is not as intuitive as editing a plain text tagged with html, and it is are pdf documents accessible? | ribera turró 31 far less maintainable because in pdf tags and content are encoded separately. n conclusions as has been seen in the analysis, pdf can be considered fairly accessible from many points of view, and its degree of compliance with the most widely recognized guidelines is fairly high. however, a surprising lack of attention is paid to complex data tables, which form a very important part of scientific articles, one of the main types of document encoded in this format. the accessibility of pdf has greatly reduced its multiplatform nature and it is to be expected that adobe will gradually resolve this point, particularly in the linux environment that has been adopted by many public administrations. an accessible and multiplatform pdf is a requisite for a really public electronic government. the format still faces three major challenges with regard to accessibility: n the creation of powerful authoring tools that allow documents to be edited easily, to be modified, and to be partially changed without having to restart the cycle of creation. there is a lack of authoring tools for creating accessible pdf documents easily and a lack of integration of the creation process in the most widely used word processors. it is to be expected that with the merger of macromedia and adobe these tools will shortly appear on the market. n a greater opening of the format by adobe in order to foster its extensibility (adobe recently applied for pdf to become an isa standard), which in digital articles is beginning to be a requirement for the annotation of mathematical or chemical formulas. (see, for example, the specific development of the infty project for reading mathematical formulas in pdf [kanahori 2006].) n a greater wealth of tags and attributes in order to express variants, and additional or complementary information, such as definitions and pronunciation. despite its shortcomings, the possibilities of the pdf with regard to accessibility have increased greatly in the latest versions, and it is now almost on a level with html. the existence of reader with several options for facilitating accessible reading increases its attractiveness even further. the experts recognize the giant steps made by the format, though they are aware of its limitations; for the moment their advice is to use the right format for the right task. finally, further research is required in order to gather the opinion of users on its accessibility. works cited adobe. 2005. creating accessible pdf documents with adobe acrobat 7.0: a guide for publishing pdf documents for use by people with disabilities. www .adobe.com/enterprise/accessibility/pdfs/acro7_pg_ ue.pdf (accessed apr. 17, 2007). ———. 2006. pdf reference: adobe portable document format version 1.7, 6th ed. www.adobe.com/devnet/acrobat/ pdfs/pdf_reference.pdf (accessed apr. 17, 2007). ———. 2007. adobe to release pdf for industry standardization. press release, jan. 29. www.adobe.com/aboutadobe/ pressroom/pressreleases/200701/012907openpdfaiim .html (accessed apr. 17, 2007). bagley, s. r., d. f. brailsford, and m. r. b. hardy. 2003. document formatting: creating reusable well-structured pdf as a sequence of component object graphic (cog) elements. presented at document engineering, grenoble, france. bates, m. j. 2002. the cascade of interactions in the digital library interface. information processing and management 38, no. 3: 381–400. clark, j. 2003. building accessible websites. indianapolis: new riders. ———. 2005. facts and opinions about pdf accessibility. a list apart, aug. 22, 2005. www.alistapart.com/articles/ pdf_accessibility (accessed apr. 17, 2007). coonin, b. 2002. establishing accessibility for e-journals: a suggested approach. library hi tech 20, no. 2: 207–20. coyne, k. p., and j. nielsen. 2001a. how to conduct usability evaluations for accessibility: methodology guidelines for testing websites and intranets with users who use assistive technology. fremont, calif.: norman nielsen group. ———. 2001b. beyond alt text: making the web easy to use for users with disabilities. fremont, calif.: norman nielsen group. ———. 2001c. web usability for senior citizens: design guidelines based on usability studies with people age 65 and older. fremont, calif.: norman nielsen group. dechilly, t. 2004. diffusion de contenus et de documents sur internet. in j. le moal, b. hidoine, and l. calderna (eds.), publier sur internet : séminaire inria 27 septembre–1er octobre 2004 aix-les-bains: 65–100.

machine sorting of library of congress call numbers articles a comprehensive approach to algorithmic machine sorting of library of congress call numbers scott wagner and corey wetherington information technology and libraries | december 2019 62 scott wagner (smw284@psu.edu) is information resources and services support specialist, penn state university libraries. corey wetherington (cjw36@psu.edu) is open and affordable course content coordinator, penn state university libraries. abstract this paper details an approach for accurately machine sorting library of congress (lc) call numbers which improves considerably upon other methods reviewed. the authors have employed this sorting method in creating an open-source software tool for library stacks maintenance, possibly the first such application capable of sorting the full range of lc call numbers. the method has potential application to any software environment that stores and retrieves lc call number information. background the library of congress classification (lcc) system was devised around the turn of the twentieth century, well before the advent of digital computing. 1 consequently, neither it nor the system of library of congress (lc) call numbers which extend it were designed with any consideration to machine readability or automated sorting.2 rather, the classification was formulated for the arrangement of a large quantity of library materials on the basis of content, gathering like items together to allow for browsing within specific topics, and in such a way that a new item may always be inserted (interfiled) between two previously catalogued items without disruption to the overall scheme. unlike, for instance, modern telephone numbers, isbns, or upcs—identifiers which pair an item with a unique string of digits having a fixed and regular format, largely irrespective of any particular characteristics of the item itself—lc call numbers specify the locations of items relative to others and convey certain encoded information about the content of those items. the library of congress summarizes the essence of the lcc in this way: the system divides all knowledge into twenty-one basic classes, each identified by a single letter of the alphabet. most of these alphabetical classes are further divided into more specific subclasses, identified by two-letter, or occasionally three-letter, combinations. for example, class n, art, has subclasses na, architecture; nb, sculpture, nd, painting; as well as several other subclasses. each subclass includes a loosely hierarchical arrangement of the topics pertinent to the subclass, going from the general to the more specific. individual topics are often broken down by specific places, time periods, or bibliographic forms (such as periodicals, biographies, etc.). each topic (often referred to as a caption) is assigned a single number or a span of numbers. whole numbers used in lcc may range from one to four digits in length, and may be further extended by the use of decimal numbers. some subtopics appear in alphabetical, rather than hierarchical, lists and are represented by mailto:smw284@psu.edu mailto:cjw36@psu.edu algorithmic machine sorting of lc call numbers | wagner and wetherington 63 https://doi.org/10.6017/ital.v38i4.11585 decimal numbers that combine a letter of the alphabet with a numeral, e.g., .b72 or .k535. relationships among topics in lcc are shown not by the numbers that are assigned to them, but by indenting subtopics under the larger topics that they are a part of, much like an outline. in this respect, it is different from more strictly hierarchical classification systems, such as the dewey decimal classification, where hierarchical relationships among topics are shown by numbers that can be continuously subdivided.3 as this description suggests, lcc cataloging practices can be quite idiosyncratic and inconsistent across different topics and subtopics, and sorting rules for properly shelf-ordering lc call numbers can be correspondingly complex, as we will see below.4 for the purposes of discussion in what follows, we divide lc call number strings into three principal substrings: the classification, the cutter, and what we will term the specification. the classification categorizes the item on the basis of its subject matter, following detailed schedules of the lcc system published by the library of congress; the cutter situates the item alongside others within its classification (often on the basis of its title and/or author5); and the specification distinguishes a specific edition, volume, format, or other characteristic of the item from others having the same author and title: hc125⏞ 𝑎 .g25313⏞ 𝑏 1997⏞ 𝑐 in the above example, the classification string (a) denotes the subject matter (in this case, general economic history and conditions of latin america), the cutter string (b) locates the book within this topic on the basis of author and/or title (following a specific encoding process), and the specification string (c) denotes the particular edition of the text (in this case, by year). each of these general substrings may contain further substrings having specific cataloging functions, and though each is constructed following certain rigid syntactical rules, a great deal of variation in format may be observed within the basic framework. the following is an inexhaustive summary of the basic syntax of each of the three call number components: • the classification string always begins with one to three letters (the class/subclass), almost always followed by one to four digits (the caption number), possibly including an additional decimal. the classification may also contain a date or ordinal number following the caption number. • the beginning of the cutter string is always indicated by a decimal point followed by a letter and at least one digit. while the majority of call numbers contain a cutter, it is not always present in all cases. among the sorting challenges posed by lc call numbers, we note in particular the “double cutter”—a common occurrence in certain subclasses— wherein the cutter string changes from alphabetic to numeric, then back to alphabetic, and finally again to numeric. triple cutters are also possible, as are dates intervening between cutters. certain cutter strings (e.g., in juvenile fiction) end with an alphabetic “work mark” composed of two or more letters. • the specification string (which may be absent on older materials) is always last, and usually contains the date of the edition, but may also include volume or other numbering, ordinal numbers, format/part descriptions (e.g., “dvd,” “manual,” “notes”), or other distinguishing information. information technology and libraries | december 2019 64 figure 1 shows example call numbers, all found within the catalog of penn state university libraries, suggesting the wide variety of possibilities: figure 1. example call numbers. as one might expect given this irregularity in syntax, systematic machine-sorting of lc call numbers is by no means trivial. to begin with, sorting procedures within the lcc system are to a certain degree contextual—that is, the sorter must understand how a given component of a call number operates within the context of the entire string in order to determine how it should sort. both integer and decimal substrings appear in lc call numbers, so that a numeral may properly precede a letter in one part of a call number (a ‘1’ sorts before an ‘a’ in the classification portion, for example: h1 precedes ha1), while the contrary may occur in another part (within the cutter, in particular, an ‘a’ may well precede a ‘1’: hb74.p65a2 precedes hb74.p6512). similarly, letters may have different sorting implications depending on where and how they appear. compare, for instance, the call numbers v23.k4 1961 and u1.p32 v.23 1993/94. the v in the former denotes the subclass of general nautical reference works and simply sorts alphabetically, whereas the v in the latter call number functions in part as an indicator that the numeral 23 refers to a specific volume number and is to be sorted as an integer rather than a decimal. such contextual cues are often tacitly understood by a human sorter, but can present considerable challenges when implementing machine sorting procedures. furthermore, the lack of uniformity or regularity in the format of call number strings poses various practical obstacles for machine sorting. taken together, these assorted complexities suggest the insufficiency of a single alphanumeric sorting procedure to adequately handle lc call numbers as unprocessed, plain text strings. literature review a thorough review of information science literature revealed little formal discussion of the algorithmic sorting of lc call numbers. if the topic has been more widely addressed in the scholarly or technical literature, we were unable to discover it. nevertheless, the general problem appears to be fairly well known. this is evident both from informal online discussions of the topic (e.g., in blog posts, message board threads, and coding forums) and from the existence of certain features of library management system (lms) and integrated library system (ils) software designed to address the issue. in this section we examine methods proffered by some of these sources, and detail how each fails to fully account for all aspects of lc call number sorting. b1190 1951 no cutter string dt423.e26 9th.ed. 2012 compound

properly accounting for the sorting of integers . the fullyprocessed strings are then ultimately ready for sorting in the rightmost column using excel’s built in sorting functionality. we note that conley and nolan’s method (hereafter “cnm”) only attempts to sort what the authors refer to as the “base call number” (i.e., the classification and cutter portions), and does not address the sorting of “volume numbers, issue numbers, or sheet numbers” (what we refer to here as the “specification”). 7 cnm stems from the tacit observation that ordinary, single-column sorting of lc call numbers is clearly inadequate in an environment like excel’s. for instance, in the following example, standard character-by-character sorting fails at the third character position, since pz30.a1 erroneously sorts before pz7.a1 (as 3 is compared to 7 in the third character position), contrary to the correct order (7 before 30). to address this, cnm normalizes the numeric portion of the class number with leading zeros so that each numeric string is of equal length, ensuring that the proper digits are compared during sorting. this entails a transformation, pz30.a1  pz0030.a1 pz7.a1  pz0007.a1 following which the strings will in fact sort correctly in an excel column. this technique appears adequate until we compare call numbers having subclasses of different length: p180.a1  p0180.a1 pz30.a1  pz0030.a1 here, while standard excel sorting will in fact properly order the resulting strings, in other applications, depending on the sorting hierarchy employed, sorting may fail in the second position if letters are sorted before numbers. hierarchy aside, it is not difficult to see the potential issues that may arise from sorting unlike portions of the call number string against one another in this way, particularly when comparing characters within the cutter string or in situations involving a “double cutter.” for instance, the call numbers b945.d4b65 1998 and b945.d41 1981b are listed here in their proper sorting order, but are in fact sorted in reverse by cnm when, in the eighth character position, 1 is sorted before b in accordance with excel’s default sorting priority. this again illustrates an essential problem of character-by-character sorting: in certain substrings we require a letters-before-numbers sorting priority, while in others a numbers-before-letters order is needed. this impasse makes clear that no single-column sorting methodology can succeed for all types of lc call numbers without significant modification to the call number string. in a blog post, dannay observed that cnm does not account for certain call number formats, particularly those of legal materials within the k classification having 3-letter class strings. 8 (the information technology and libraries | december 2019 66 same would also be true in the d classification, where 3-letter strings also appear.) although minor modification of portions of the function code (e.g., replacing certain ‘2’s with ‘3’s) would be sufficient to alleviate this particular issue, dannay proposed instead to employ placeholder characters to normalize the classification string and avoid instances of alphabetic characters being compared against numeric ones. dannay’s method (dm) normalizes various parts of the classification string, including the subclass, caption, and decimal portions: q171.t78  q**0171.0.t78 qa9.r8  qa*0009.0.r8 (here, of course, it is imperative that the chosen placeholder character sort before all letters in the sorting hierarchy.) dm thus successfully avoids the issue of comparing classification strings of unequal length or format. nevertheless, despite the improvements of dm over cnm, both approaches are ultimately unable to properly process certain types of common lc call numbers. for example, call numbers with dates preceding the cutter (e.g., gv722 1936.h55 2006) and call numbers without cutters (e.g., b1205 1958) both result in errors, as do those containing the aforementioned “double cutters.” furthermore, as we previously noted, neither dm nor cnm were designed to handle any portion of the specification string following the cutter, where the presence of ordinal and volumetype numbering is commonplace. hence neither method is able to properly order the quite ordinary pair of call numbers ac1.g7 v.19 and ac1.g7 v.2, since the first digit of each’s volume number is compared and ordered numerically (i.e., character-by-character), resulting in a mis-sort. though neither dn nor cnm is ultimately comprehensive (nor designed to be), both methods contain valuable insights and strategies that inform our own approach to the problem. software review available software solutions for sorting lc call numbers appear to be nearly as scant as literature on the subject. while github contains a handful of programs that attempt to address the problem, we found none which could be considered comprehensive. table 1 is a summary of those programs we discovered and were able to examine. the “sqlite3-lccn-extension” program is an extension for sqlite 3 which provides a collation for normalizing lc call numbers, executing from a sqlite client shell. we discovered several limitations in its ability to sort certain call number formats similar to those discussed above in the literature review. for instance, the program cannot correctly sort specification integers (e.g., it sorts v.13 before v.3) or call numbers lacking cutter strings (e.g., it sorts b 1190.a1 1951 before b 1190 1951). we found similar issues with “js-loc-callnumbers,” a javascript program with a web interface into which a list of call numbers can be pasted. the program transforms the call numbers into normalized strings, which are then sorted and displayed to the user. however, we observed that it does not account for dates or ordinal numbers in the classification string, nor can it correctly sort call numbers lacking caption numbers.9 algorithmic machine sorting of lc call numbers | wagner and wetherington 67 https://doi.org/10.6017/ital.v38i4.11585 program and author app-type, interface repository url last update

in scope. the “lcsortable” script is a google sheets scheme for normalizing lc call numbers into a separate column for sorting, very much like cnm and dm. its normalization routine appears to conflate decimals and integers, though, leading to transformations such as hf5438.5.p475 2001  hf5438.0005.p04752001 which would clearly result in a great deal of incorrect sorting across a wide array of lc call number formats. the command-line-based python program “library-callnumber-lc” processes a call number and returns a normalized sort key, but is not intended to store or sort groups of call numbers. it cannot adequately handle compound specifications or cutters containing consecutive letters (e.g., s100.bc123 1985), and does not appear to preserve the demarcation between a caption integer and caption decimal (i.e., the decimal point), thereby commingling integer and decimal sorting logic. lastly, “library-of-congress-system” is a tutorial/training program written in python that runs from the command line and supplies a list of call numbers for the user to sort. it does not draw call numbers from a static collection nor allow call numbers to be input by the user; rather, it randomly generates call numbers within certain parameters and following a https://github.com/macdewar/sqlite3-lccn-extension https://github.com/macdewar/sqlite3-lccn-extension

information technology and libraries | december 2019 68 prescribed pattern. as such, we were not able to satisfactorily test its sorting capabilities for the kind of use-case scenario under discussion. we did not evaluate the remaining two github programs, “lc_call_number_compare” and “lc_callnumber,” as we could not get the former, a javascript es6 module, to execute, and as the latter, a ruby application which we did not attempt to install, evidently remains unfinished: its github documentation lists “normalization: create a string that can be compared with other normalized strings to correctly order the call numbers” as the among tasks yet to be completed. in addition to these open resources, we examined lc sorting capability within the commercial lms/ils software we had at hand. the marc (machine-readable cataloging) 21 protocol, a widely used international standard for formatting bibliographic data, provides a specific syntax for cataloging lc call numbers for the purposes of machine parsing.10 symphony workflows, the lms licensed by penn state university libraries from sirsidynix (and thus the only one available for our direct examination), contains within its search module a call number browsing feature which attempts to sort call numbers in shelving order via “shelving ids,” call number strings rendered from each item’s marc 21 “050” data field for sorting purposes. while these shelving ids are not visible within workflows (that is, they operate in the background), they can be accessed as plain text strings via bluecloud analytics, a separate, sirsidynix-branded data assessment and reporting tool peripheral to the lms. examination of these sort keys revealed integer normalization strategies similar to those of dm and cnm, with additional processing of volume-type numbering within the specification string. however, these shelving ids are similarly unable to correctly sort “double cutter” substrings and other syntactic complexities, such as ordinal numbers appearing in the classification. the following shelving id transformations of two call numbers in the penn state university libraries catalog, for instance, fail to properly account for the ordinal numbers which appear within the classification: e507.5 36th.v47 2003  e 000507.5 36th.v47 2003 e507.5 5th.c36 2000  e 000507.5 5th.c36 2000 consequently, and as expected, these two call numbers sort incorrectly within workflows’ call number browsing panes.11 proposed parsing and sorting methodology given the sorting difficulties inherent in the single-column approaches outlined above, we suggest a multi-column, tiered sorting procedure in which only like portions of the call number are compared to one another. this requires the call number to be processed, its various components identified, and each component appropriately sorted according to its specific typ e. this, in turn, requires a sorting algorithm which can identify like substrings by scanning for specific patterns and cues. “shelf reading” is a term for the common practice of verifying the correct ordering of items filed on a library shelf, typically unaided by technology, and our approach is primarily informed by the kind of mental procedures one undertakes when performing such sorting “in one’s head.”12 perhaps the most significant component of this process involves recognizing and interpreting the role and logic of specific types of substrings and identifying their positions within the sorting hierarchy. the overall design of the lc classification, from class to subclass to caption, constitutes algorithmic machine sorting of lc call numbers | wagner and wetherington 69 https://doi.org/10.6017/ital.v38i4.11585 a left-to-right progression from general to specific, and the classification portion of a call number can be interpreted as a series of containers holding items of increasingly narrow scope, some of which may be empty (that is, absent). this creates a structure that has a linear, hierarchical aspect, but also contains within it subcategories that share a common position within the structure. the priority that a subcategory (or container) is afforded in the sorting process depends first upon its position in the linear hierarchy, and subsequently on the depth ascribed to it relative to other subcategories that share the same position. call numbers indicate a subcategory’s position in the linear dimension by including or expanding sections; its depth within a given position is encoded in the character or series of characters chosen to represent it. thus, the sorting process may be regarded as a comparison of the paths that two call numbers denote through this structure, and the point at which the paths diverge is then the decisive point in determining an item’s position relative to others. this inflection point may occur at any juncture of the comparison, from the first character to the last. given these observations, a comprehensive machine-sorting strategy must observe the following provisions: 1. characters in call numbers should only be compared to characters that occupy an equivalent section of another call number. (“like compared to like.”) 2. within these designated sections, characters should only be compared to characters that occupy a corresponding position (place value) within that section. 3. if call numbers are identical up to the point that one of them lacks a section that the other call number possesses, the one with the “missing” section is ordered first. this is in keeping with the convention that items occupying a more general level in the hierarchy are ordered before those occupying a more specific one. (this principle is often summarized in shelfreading tutorials as “nothing before something.”) 4. if call numbers are identical up to the point that one of them lacks a character in a given position within a particular section that the other call number possesses, the one missing the character is ordered first. again, this preserves the general to specific scheme of lcc sorting. (another instance of “nothing before something.”) 5. whole numbers (e.g., caption integers, volume numbers) must be distinguished from decimals. for character-by-character sorting to work in sections of the call number containing integers, the length of whole numbers must be normalized to assure each digit is compared to another of equal place value. application of methodology shelfreader is a software application designed by the authors to improve the speed and accuracy of the shelf-reading process in collections filed using the library of congress system—and, to our knowledge, is the first such application to do so. it was coded by scott wagner in php and javascript, uses mysql for data storage and sorting, and is deployed as a web application. shelfreader allows the user to scan library items in the order they are shelved and receive feedback regarding any mis-shelved items. the program receives an item’s unique barcode identification via a barcode scanner, assembles a rest request incorporating the barcode, and sends it to an api connected to the lms. the application then processes the response, retrieving the title and call number of the item, along with information about the item’s status (for example, if it has been marked as lost or missing). the call number is passed off to the sorting algorithm, information technology and libraries | december 2019 70 which processes it and assigns it a position among the set of call numbers recorded during that session. a user interface then presents a “virtual shelf” to the user displaying a graphical representation of the items in the order they were scanned. when items are out of place on the shelf, the program calculates the fewest number of moves needed to correct the shelf and presents the necessary corrections for the user to perform until the shelf is properly ordered. a screenshot depicting the shelfreader gui during a typical shelf-reading session is presented in figure 2. figure 2. a screenshot of the shelfreader gui, showing an incorrectly filed item (highlighted in blue text) and its proper filing position (represented by the green band). shelfreader’s sorting strategy consists of breaking call numbers into elemental substrings and arranging those parts in a database table so that any two call numbers may be compared exclusively on the basis of their corresponding parts. to this end, a base set of call number components was established. these are shown in table 2, along with their abbreviations (for ease in reference), maximum length, and corresponding mysql data types. the specific mysql data type determines the kind of sorting employed in each column: • varchar accepts alphanumeric string data. sorting is character by character, numbers before letters. • integer accepts numerical data; numbers are evaluated as whole numbers. • decimal accepts decimal values. specifying the overall length of the column and the number of characters to the right of the decimal point has the effect of adding zeros as placeholders in any empty spaces to the right of the last digit. the values are then compared digit by digit. algorithmic machine sorting of lc call numbers | wagner and wetherington 71 https://doi.org/10.6017/ital.v38i4.11585 • timestamp a date/time value that defaults to the date and time the entry is made. this orders call numbers that are identical (i.e., multiple copies of the same item) in the order they are scanned. section, component abbreviation max. length mysql data type classification class/subclass sbc 3 varchar caption number, integer part ci 4 integer caption number, decimal part cdl 16 decimal caption date cdt 4 varchar caption ordinal co 16 integer caption ordinal indicator coi 2 varchar cutter first cutter, alphabetical part c1a 3 varchar first cutter, numerical part c1n 16 decimal first cutter date cd 4 integer second cutter, alphabetical part c2a 3 varchar second cutter, numerical part c2n 16 decimal second cutter date cd2 4 integer third cutter, alphabetical part c3a 3 varchar third cutter, numerical part c3n 16 decimal specification specification sp 256 varchar timestamp — — mysql timestamp table 2. shelfreader call number components and data types. when parsing a call number, it must be assumed that each call number may contain all of the components identified above. the following is a general outline of the parsing algorithm which processes the call number: information technology and libraries | december 2019 72 1. an array is created from the call number. each character, including spaces, is an element of the array. 2. a second array is then created to serve as a template for each call number, replacing the actual characters with ones indicating data type. for example, all integers are replaced with ‘i’s. this makes pattern matching and data-type testing simpler. 3. pattern matching is used to identify the presence or absence of landmarks such cutters, spaces, volume-type numbering, etc. 4. when landmarks are identified, their beginning and ending positions in the call number string are noted. 5. component strings are created by looping through the appropriate section of the call number template, constructing a string in which the template characters are replaced by the actual characters in the call number string and continuing until a space, th e end of the string, or an incompatible character is encountered. 6. where needed, whole numbers strings are normalized to uniform length. dividing a call number into its component parts and placing those parts in separate columns in a database table, then, effectively creates a sort key that may be used for ordering. this key occupies a row of the table, and is an inflated representation of the call number insofar as it makes use of the maximum possible string length of each component type. it contains the characters of each component the call number possesses, and any empty columns serve as placeholders for components it does not possess. when two call numbers are compared, sorting proceeds through each successive column, each component (and each character within each component) serving as a potential break point within the sorting process. we note that every column (with the exception of the specification) contains exclusively alphabetic or numeric data, so that numbers and letters are never compared in th ose sections of the call number string. (the use of spaces in the specification string effectively accounts for the mixed alphanumeric data type.) some additional points of clarification regarding the algorithm’s multi-column approach to sorting are worth mentioning: 1. any lowercase alphabetic characters are converted to uppercase before processing in order to ensure that letter case does not affect sorting. 2. components are arranged in the database table from left to right in the order they occur in the call number. 3. if a call number does not contain a given component, the column is left empty (in the case of a varchar column) or is assigned a zero value (in the case of numeric columns). 4. empty columns and zero columns sort before columns containing data. 5. in columns designated as varchar columns, numbers are compared as whole numbers . this means that, in order to sort correctly, the length of any number stored must be normalized to a uniform length (6 places) by adding leading zeros. for example, 17 must be normalized to “000017.” 6. sorting proceeds column by column, provided the call numbers are identical. when the first difference is encountered, sorting is complete. algorithmic machine sorting of lc call numbers | wagner and wetherington 73 https://doi.org/10.6017/ital.v38i4.11585 table 3 shows two randomly selected call numbers of rather common configuration, along with the corresponding sort keys created by shelfreader: e169.1.b634 2002 e169.1.b653 1987 }  sbc ci cdl cdt co coi c1a c1n cd c2a c2n cd2 c3a c3n sp e 0169 0.10000 0 b 0.6340000000 0002002 e 0169 0.10000 0 b 0.6530000000 0001987 table 3. example shelfreader sort-key processing of two similar call numbers. in this first example, sorting is complete when 3 is compared to 5 in the first numerical cutter (c1n) column. (note that we have here truncated the length of certain strings for space and readability.) to illustrate how the application handles call numbers having heterogenous formats, table 4 shows the sort keys created from two call numbers in an example mentioned above, one with a “double cutter” and one without: b945.d4b65 1998 b945.d41 1981b }  sbc ci cdl cdt co coi c1a c1n cd c2a c2n cd2 c3a c3n sp

by pushing the second cutter (b65) in the first call number into the c2a and c2n columns, the issue of comparing incompatible sections of the call number is avoided, as the 1 in the second call number is compared to the placeholder 0 in the first. when the sorting routine reaches this position, it terminates, and any subsequent characters are ignored. aspects of this multi-column approach may seem counterintuitive at first, but the method mimics what we do when we order call numbers mentally. one compares two call numbers character by character within these component categories until encountering a difference, or until a character or entire category in one of the call numbers is found to be absent. results shelfreader’s sorting method is powerful, accurate, and has been extensively tested without issue in a number of different academic libraries within penn state’s statewide system. the application accurately sorts all valid lc call numbers (with the exception of those for certain cartographic materials in the g1000 – g9999 range, which sometimes employ a different syntax and sorting order) as well those of the national library of medicine classification system (which augments information technology and libraries | december 2019 74 lcc with class w and subclasses qs – qz) and the national library of canada classification (which adds to lcc the subclass fc, for canadian history). while there may conceivably be valid lc or lcextended call numbers having exotic formats that would fail to correctly sort in shelfreader, we are not aware of any examples (outside of, once again, the g1000 – g9999 range), nor have we received reports of any from users. in addition to verifying proper shelf-ordering, shelfreader contains a number of other features useful for stacks maintenance. the program can identify shelved items that are still checked out to patrons, have been marked missing or lost, or are flagged as in transit between locations, and often reveals items which have been inadvertently “shadowed” (i.e., excluded from public-facing library catalogs) or have shelf labels which do not match their catalogued call numbers. the gui has different modes to accommodate the user’s preferred view (both single shelf and multi-shelf, stacks views), and allows for a good deal of flexibility in how and when the user wishes to make and record shelf corrections. a reports module is also included, which tracks shelving statistics and other useful information for later reference. the shelfreader application code (including the full sorting algorithm) is freely available via an mit license at https://github.com/scodepress/shelfreader. while shelfreader was developed and tested using the collections and systems of penn state university libraries, its architecture could be adapted and configured for use with other library apis and adjusted to suit local practices within the general confines of the lc call number structure.13 we can also envision a wide array of potential applications of the sorting functionality within other software environments, and we welcome and encourage users to pursue innovative adaptations of the method.

lcc is described in detail in chapters xiii and xiv (pp. 221-51). 2 indeed, as lamontagne asserts, “the classification was constructed [ . . . ] to provide for the needs of the library of congress, with no thought to its possible adoption by other libraries. in fact, the library has never recommended that other libraries adopt its system . . . ” (ibid., p. 252). nevertheless, lcc is employed by

present a challenge for making the program easily adaptable to libraries using distinct web services. a strategy to adapt the program would need to account for potential differences in barcode structure, structure and naming conventions in the rest request, and structure and naming conventions within the server response from institution to institution. it is possible that these issues could be resolved via a configuration file made available to the user, but no attempt to address this issue has been undertaken as of yet. https://scholarsphere.psu.edu/downloads/9cn69m421z

smartphones: a potential discovery tool | starkweather and stoward 187 smartphones: a potential discovery tool wendy starkweather and eva stowers the anticipated wide adoption of smartphones by researchers is viewed by the authors as a basis for developing mobile-based services. in response to the unlv libraries’ strategic plan’s focus on experimentation and outreach, the authors investigate the current and potential role of smartphones as a valuable discovery tool for library users. w hen the dean of libraries announced a discovery mini-conference at the university of nevada las vegas libraries to be held in spring 2009, we saw the opportunity to investigate the potential use of smartphones as a means of getting information and services to students. being enthusiastic users of apple’s iphone, we and the web technical support manager, developed a presentation highlighting the iphone’s potential value in an academic library setting. because wendy is unlv libraries’ director of user services, she was interested in the applicability of smartphones as a tool for users to more easily discover the libraries’ resources and services. eva, as the health sciences librarian, was aware of a long tradition of pda use by medical professionals. indeed, first-year bachelor of science nursing students are required to purchase a pda bundled with select software. together we were drawn to the student-outreach possibilities inherent in new smartphone applications such as twitter, facebook, and myspace. n presentation our brief review of the news and literature about mobile phones in general provided some interesting findings and served as a backdrop for our presentation: n a total of 77 percent of internet experts agreed that the mobile phone would be “the primary connection tool” for most people in the world by 2020.1 the number of smartphone users is expected to top 100 million by 2013. there are currently 25 million smartphone users, with sales in north america having grown 69 percent in 2008.2 n smartphones offer a combination of technologies, including gps tracking, digital cameras, and digital music, as well as more than fifty-thousand specialized apps for the iphone and new ones being designed for the blackberry and the palm pre.3 the palm pre offered less than twenty applications at its launch, but one million apllication downloads had been performed by june 24, 2009, less than a month after launch.4 n the 2009 horizon report predicts that the time to adoption of these mobile devices in the educational context will be “one year or less.”5 data gathered from campus users also was presented, providing another context. in march 2009, a survey of university of california, davis (uc-davis) students showed that 43 percent owned a smartphone.6 uc-davis is participating in apple’s university education forum. here at unlv, 37 percent of students and 26 percent of faculty and staff own a smartphone.7 the presentation itself highlighted the mobile applications that were being developed in several libraries to enhance student research, provide library instruction, and promote library services. two examples were abilene christian university (http://www.acu.edu/technology/ mobilelearning/index.html), which in fall 2008 distributed iphones and ipod touches to the incoming freshman class; and stanford university (http://www.stanford .edu/services/wirelessdevice/iphone/) which participates in “itunes u” (http://itunes.stanford.edu/). if the libraries were to move forward with smartphone technologies, it would be following the lead of such universities. readers also may be interested in joan lippincott’s recent concise summary of the implications of mobile technologies for academic libraries as well as the chapter on library mobile initiatives in the july 2008 library technology report.8 n goals: a balancing act ultimately the goal for many of these efforts is to be where the users are. this aspiration is spelled out in unlv libraries’ new strategic plan relating to infrastructure evolution, namely, “work towards an interface and system architecture that incorporates our resources, internal and external, and allows the user to access from their preferred starting point.”9 while such a goal is laudable and fits very well into the discovery emphasis of the mini-conference presentation, we are well aware of the need for further investigation before proceeding directly to full-scale development of a complete suite of mobile services for our users. of critical importance is ascertaining where our users are and determining whether they want us to be there and in what capacity. the value of this effort is demonstrated in booth’s research report on student interest in emerging technologies at ohio state university. the report includes the results of an extensive environmental survey of their wendy starkweather (wendy.starkweather@unlv.edu) is director, user services division, and eva stowers (eva.stowers @unlv.edu) is medical/health sciences librarian at the university of nevada las vegas libraries. 188 information technology and libraries | december 2009 library users. the study is part of ohio state’s effort to actualize their culture of assessment and continuous learning and to use “extant local knowledge of user populations and library goals” to inform “homegrown studies to illuminate contextual nuance and character, customization that can be difficult to achieve when using externally developed survey instruments.”10 unlv libraries are attempting to balance early experimentation and more extensive data-driven decision-making. the recently adopted strategic plan includes specific directions associated with both efforts. for experimentation, the direction states, “encourage staff to experiment with, explore, and share innovative and creative applications of technology.”11 to that end, we have begun working with our colleagues to introduce easy, small-scale efforts designed to test the waters of mobile technology use through small pilot projects. “text-a-librarian” has been added to our existing group of virtual reference service, and we introduced a “text the call number and record” service to our library’s opac in july 2009. unlv libraries’ strategic plan helps foster the healthy balance by directing library staff to “emphasize data collection and other evidence based approaches needed to assess efficiency and effectiveness of multiple modes and formats of access/ownership” and “collaborate to educate faculty and others regarding ways to incorporate library collections and services into education experiences for students.”12 action items associated with these directions will help the libraries learn and apply information specific to their users as the libraries further adopt and integrate mobile technologies into their services. as we begin our planning in earnest, we look forward to our own set of valuable discoveries. references 1. janna anderson and lee rainie, the future of the internet iii, pew internet & american life project, http://www.pewinternet

digital rights management (drm) systems to lock-down digital content in an unprecedented fashion; and the erosion of net neutrality, which ensures that all internet traffic is treated equally—are examined in detail and their potential impact on libraries is assessed. how legislatures, the courts, and the commercial marketplace treat these issues will strongly influence the future of digital information for good or ill. editor's note: this article was submitted in honor of the fortieth anniversaries of lita and ital. b logs. digital photo and video sharing. podcasts. rip/mix/burn. tagging. vlogs. wikis. these buzzwords point to a fundamental social change fueled by cheap personal computers (pcs) and servers, the internet and its local wired/wireless feeder networks, and powerful, low-cost software. citizens have morphed from passive media consumers to digital-media producers and publishers. libraries and scholars have their own set of buzzwords: digital libraries, digital presses, e-prints, institutional repositories, and open-access (oa) journals, to name a few. they connote the same kind of change: a democratization of publishing and media production using digital technology. it appears that we are on the brink of an exciting new era of internet innovation: a kind of digital utopia. gary flake of microsoft has provided one striking vision of what could be (with a commercial twist) in a presentation entitled “how i learned to stop worrying and love the imminent internet singularity,” and there are many other visions of possible future internet advances.1 when did this metamorphosis begin? it depends on who you ask. let’s say the late 1980s, when the internet began to get serious traction and an early flowering of noncommercial digital publishing occurred. in the subsequent twenty-odd years, publishing and media production went from being highly centralized, capital-intensive analog activities with limited and welldefined distribution channels, to being diffuse, relatively low-cost digital activities with the global internet as their distribution medium. not to say that print and conventional media are dead, of course, but it is clear that their era of dominance is waning. the future is digital. nor is it to say that entertainment companies (e.g., film, music, radio, and television companies) and information companies (e.g., book, database, and serial publishers) have ceded the digital-content battlefield to the upstarts. quite the contrary. high-quality, thousand-page-per-volume scientific journals and hollywood blockbusters cannot be produced for pennies, even with digital wizardry. information and entertainment companies still have an important role to play, and, even if they didn’t, they hold the copyrights to a significant chunk of our cultural heritage. entertainment and information companies have understood for some time that they must adapt to the digital environment or die, but this change has not always been easy, especially when it involves concocting and embracing new business models. nonetheless, they intend to thrive and prosper—and to do whatever it takes to succeed. as they should, since they have an obligation to their shareholders to do so. the thing about the future is that it is rooted in the past. culture, even digital culture, builds on what has gone before. unconstrained access to past works helps determine the richness of future works. inversely, when past works are inaccessible except to a privileged minority, future works are impoverished. this brings us to a second trend that stands in opposition to the first. put simply, it is the view that intellectual works are property; that this property should be protected with the full force of civil and criminal law; that creators have perpetual, transferable property rights; and that contracts, rather than copyright law, should govern the use of intellectual works. a third trend is also at play: the growing use of digital rights management (drm) technologies. when intellectual works were in paper (or other tangible forms), they could only be controlled at the object-ownership or object-access levels (a library controlling the circulation of a copy of a book is an example of the second case). physical possession of a work, such as a book, meant that the user had full use of it (i.e., the user could read the entire book and photocopy pages from it). when works are in digital form and are protected by some types of drm, this may no longer be true. for example, a user may only be able to view a single chapter from a drm-protected e-book and may not be able to print it. the fourth and final trend deals with how the internet functions at its most fundamental level. the internet was designed to be content-, application-, and hardware-neutral. as long as certain standards were met, the network did not discriminate. one type of content was not given preferential delivery speed over another. one type of strong copyright + drm + weak net neutrality = digital dystopia? charles w. bailey jr. charles w. bailey jr. (cbailey@digital-scholarship.com) is assistant dean for digital library planning and development at university of houston libraries. digital dystopia | bailey 117 content was not charged for delivery while another was free. one type of content was not blocked (at least by the network) while another was unhindered. in recent years, network neutrality has come under attack. the collision of these trends has begun in courts, legislatures, and the marketplace. it is far from over. as we shall see, its outcome will determine what the future of digital culture looks like. ฀ stronger copyright: 1790 versus 2006 copyright law is a complex topic. it is not my intention to provide a full copyright primer here. (indeed, i will assume that the reader understands some copyright basics, such as the notion that facts and ideas are not covered by copyright.) rather, my aim is to highlight some key factors about how and why united states copyright law has evolved and how it relates to the digital problem at hand. three authors (lawrence lessig, professor of law at the stanford law school; jessica litman, professor of law at the wayne state university law school; and siva vaidhyanathan, assistant professor in the department of culture and communication at new york university) have done brilliant and extensive work in this area, and the following synopsis is primarily based on their contributions. i heartily recommend that you read the cited works in full. the purpose of copyright let us start with the basis of u.s. copyright law, the constitution’s “progress clause”: “congress has the power to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.”2 copyright was a bargain: society would grant creators a time-limited ability to control and profit from their works before they fell into the public domain (where works are unprotected) because doing so resulted in “progress of science and useful arts” (a social good). regarding the progress clause, lessig notes: it does not say congress has the power to grant “creative property rights.” it says that congress has the power to promote progress. the grant of power is its purpose, and its purpose is a public one, not the purpose of enriching publishers, nor even primarily the purpose of rewarding authors.3 however, entertainment and information companies can have a far different view, as illustrated by this quote from jack valenti, former president of the motion picture association of america: “creative property owners must be accorded the same rights and protections resident in all other property owners in the nation.”4 types of works covered when the copyright act of 1790 was enacted, it protected published books, maps, and charts written by living u.s. authors as well as unpublished manuscripts by them.5 the act gave the author the exclusive right to “print, reprint, publish, or vend” these works. now, copyright protects a wide range of published and unpublished “original works of authorship” that are “fixed in a tangible medium of expression” without regard for “the nationality or domicile of the author,” including “1. literary works; 2. musical works, including any accompanying words; 3. dramatic works, including any accompanying music; 4. pantomimes and choreographic works; 5. pictorial, graphic, and sculptural works; 6. motion pictures and other audiovisual works; 7. sound recordings; 8. architectural works.”6 rights in contrast to the limited print publishing rights inherent in the copyright act of 1790, current law grants copyright owners the following rights (especially notable is the addition of control over derivative works, such as a play based on a novel or a translation): ฀ to reproduce the work in copies or phonograph records; ฀ to prepare derivative works based upon the work; ฀ to distribute copies or phonograph records of the work to the public by sale or other transfer of ownership, or by rental, lease, or lending; ฀ to perform the work publicly, in the case of literary, musical, dramatic, and choreographic works, pantomimes, and motion pictures and other audiovisual works; ฀ to display the copyrighted work publicly, in the case of literary, musical, dramatic, and choreographic works, pantomimes, and pictorial, graphic, or sculptural works, including the individual images of a motion picture or other audiovisual work; and ฀ in the case of sound recordings, to perform the work publicly by means of a digital audio transmission.7 duration the copyright act of 1790 granted authors a term of fourteen years, with one renewal if the author was still living (twenty-eight years total).8 now the situation is much more complex, and, rather than trying to review the details, i’ll provide the following example. for a personal author who produced a work on or after january 1, 1978, it is covered for the life of the author plus seventy years.9 so, assuming 118 information technology and libraries | september 2006 an author lives an average seventy-five years, the work would be covered for 144 years, which is approximately 116 years longer than in 1790. registration registration was required by the copyright act of 1790, but very few eligible works were registered from 1790 to 1800, which enriched the public domain.10 now registration is not required, and no work enriches the public domain until its term is over, even if the author (or the author’s descendants) have no interest in the work being under copyright, or it is impossible to locate the copyright holder to gain permission to use his or her works (creating so-called “orphan works”). drafting of legislation by 1901, copyright law had become fairly esoteric and complex, and drafting new copyright legislation had become increasingly difficult. consequently, congress adopted a new strategy: let those whose commercial interests were directly affected by copyright law deliberate and negotiate with each other about copyright law changes, and use the results of this process as the basis of new legislation.11 over time, this increasingly became a dialogue among representatives of entertainment, high-tech, information, and telecommunications companies; other parties, such as library associations; and rights-holder groups (e.g., ascap). since these parties often had competing interests, the negotiations were frequently contentious and lengthy. the resulting laws created a kind of crazy quilt of specific exceptions for the deals made during these sessions to the ever-expanding control over intellectual works that copyright reform generally engendered. since the public was not at the table, its highly diverse interests were not directly represented, and, since stakeholder industries lobby congress and the public does not, the public’s interests were often not well served. (there were some efforts by special interest groups to represent the public on narrowly focused issues.) frequency of copyright term legislation with remarkable restraint, congress, in its first hundred years, enacted one copyright bill that extended the copyright term and one in its next fifty; however, starting in 1962, it passed eleven bills in the next forty years.12 famously, jack valenti once proposed that copyright “last forever less one day.”13 by continually extending copyright terms in a serial fashion, congress may grant him his wish. licenses in 1790, copyrighted works were sold and owned. today, many digital works are licensed. licenses usually fall under state contract law rather than federal copyright law.14 licensed works are not owned, and the first-sale doctrine is not in effect.15 while copyright is the legal foundation of licenses (i.e., works can be licensed because licensors own the copyright to those works), licenses are contracts, and contract provisions trump user-favorable copyright provisions, such as fair use, if the licensor chooses to negate them in a license. criminal and civil penalties in 1790 there were civil penalties for copyright infringement (e.g., statutory fines of “50 cents per sheet found in the infringer ’s possession”).16 now there are criminal copyright penalties, including felony violations that can result in a maximum of five years of imprisonment and fines as high as $250,000 for first-time offenders; civil statutory fines that can range as high as $150,000 per infringement (if infringement is “willful”), and other penalties.17 once the copyright implications of digital media and the internet sunk in, entertainment and information companies were deeply concerned: digital technologies made creating perfect copies effortless, and the internet provided a free (or low-cost) way to distribute content globally. congress, primarily spurred on by entertainment companies, passed several laws aimed at curtailing perceived digital “theft” through criminal penalties. under the 1997 no electronic theft (net) act, copyright infringers face “up to 3 years in prison and/or $250,000 fines,” even for noncommercial infringement.18 under the 1998 digital millennium copyright act (dmca), those who defeat technological mechanisms that control access to copyrighted works (a process called “circumvention”) face a maximum of five years in prison and $500,000 in fines.19 effect of copyright on average citizens in 1790, copyright law had little effect on citizens. the average person was not an author or publisher, private use of copyrighted materials was basically unregulated, the public domain was healthy, and many types of works were not covered by copyright at all. in 2006, ฀ virtually every type of work imaginable is under automatic copyright protection for extended periods of time; ฀ private use of digital works is increasingly visible and of concern to copyright holders; ฀ the public domain is endangered; and ฀ ordinary citizens are being prosecuted as “pirates” under draconian statutory and criminal penalties. digital dystopia | bailey 119 regarding this development, lessig says: for the first time in our tradition, the ordinary ways in which individuals create and share culture fall within the reach of the regulation of the law, which has expanded to draw within its control a vast amount of culture and creativity that it never reached before. the technology that preserved the balance of our history—between uses of our culture that were free and uses of our culture that were only upon permission—has been undone. the consequence is that we are less and less a free culture, more and more a permission culture.20 how has copyright changed since the days of the founding fathers? as we have seen, there has been a shift in copyright law (and social perceptions of it) from ฀ promoting progress to protecting intellectual property owners’ “rights”; ฀ from covering limited types of works to covering virtually all types of works; ฀ from granting only basic reproduction and distribution rights to granting a much wider range of rights; ฀ from offering a relatively short duration of protection to offering a relatively long (potentially perpetual) one; ฀ from requiring registration to providing automatic copyright; ฀ from drafting laws in congress to drafting laws in work groups of interested parties dominated by commercial representatives; ฀ from making infrequent extensions of copyright duration to making frequent ones; ฀ from selling works to licensing them; ฀ from relatively modest civil penalties to severe civil and criminal penalties; and ฀ from ignoring ordinary citizens’ typical use of copyrighted works to branding them as pirates and prosecuting them with lawsuits. (regarding lawsuits filed by the recording industry association of america against four students, lessig notes: “if you added up the claims, these four lawsuits were asking courts in the united states to award the plaintiffs close to $100 billion—six times the total profit of the film industry in 2001.”)21 complicating this situation further is intense consolidation and increased vertical integration in the entertainment, information, telecommunications, and other high-tech industries involved in the internet.22 this vertical integration has implications for what can be published and the free flow of information. for example, a company that publishes books and magazines, produces films and television programs, provides internet access and digital content, and provides cable television services (including broadband internet access) has different corporate interests than a company that performs a single function. these interrelated interests may affect not only what information is produced and whether competing information and services are freely available through controlled digital distribution channels, but corporate perceptions of copyright issues as well. one of the ironies of the current copyright situation is this: if creative works are by nature property, and stealing property is (and has always been) wrong, then some of the very industries that are demanding that this truth be embodied in copyright law have, in the past, been pirates themselves, even though certain acts of piracy may have been legal (or appeared to be legal) under then-existing copyright laws.23 lessig states: if “piracy” means using the creative property of others without their permission—if “if value, then right” is true—then the history of the content industry is a history of piracy. every important sector of “big media” today—film, records, radio, and cable tv—was born of a kind of piracy so defined. the consistent story is how last generation’s pirates join this generation’s country club—until now.24 let’s take a simple case: cable television. early cable television companies used broadcast television programs without compensating copyright owners, who branded their actions as piracy and filed lawsuits. after two defeats in the supreme court, broadcast television companies won a victory (of sorts) in congress, which took nearly thirty years to resolve the matter: cable television companies would pay, but not what broadcast television companies wanted; rather they would pay fees determined by law.25 of course, this view of history (big media companies as pirates in their infancy) is open to dispute. for the moment, let’s assume that it is true. put more gently, some of the most important media companies of modern times flourished because of relatively lax copyright control, a relatively rich public domain, and, in some cases, a societal boon that allowed them to pay statutory license fees— which are compulsory for copyright owners—instead of potentially paying much higher fees set by copyright owners or being denied use at all. today, the very things that fostered media companies’ growth are under attack by them. the success of those attacks is diminishing the ability of new digital content and service companies to flourish and, in the long run, may diminish even big media’s ability to continue to thrive as a permission culture replaces a permissive culture. several prominent copyright scholars have suggested copyright reforms to help restore balance to the copyright system. james boyle, professor of law at the duke university law school, recommends a twenty-year copyright term with “a broadly defined fair use protection for journalistic, teaching, and parodic uses—provided that those uses were not judged to be in bad faith by a jury applying the ‘beyond a reasonable doubt’ standard.”26 120 information technology and libraries | september 2006 william w. fisher iii, hale and dorr professor of intellectual property law at harvard university law school, suggests that “we replace major portions of the copyright and encryption-reinforcement models with . . . a governmentally administered reward system” that would put in place new taxes and compensate registered copyright owners of music or films with “a share of the tax revenues proportional to the relative popularity of his or her creation,” and would “eliminate most of the current prohibitions on unauthorized reproduction, distribution, adaptation, and performance of audio and video recordings.”27 lessig recommends that copyright law be guided by the following general principles: (1) short copyright terms, (2) a simple binary system of protected/not protected works without complex exceptions, (3) mandatory renewal, and (4) a “prospective” orientation that forbids retrospective term extensions.28 (previously, lessig had proposed a seventy-five-year term contingent on five-year renewals). he suggests reinstating the copyright registration requirement using a flexible system similar to that used for domain name registrations. he favors works having copyright marks, and, if they are not present, he would permit their free use until copyright owners voice their opposition to this use (uses of the work made prior to this point would still be permitted). litman wants a copyright law “that is short, simple, and fair,” in which we “stop defining copyright in terms of reproduction” and recast copyright as “an exclusive right of commercial exploitation.”29 litman would eliminate industry-specific copyright law exceptions, but grant the public “a right to engage in copying or other uses incidental to a licensed or legally privileged use”; the “right to cite” (even infringing works); and “an affirmative right to gain access to, extract, use, and reuse the ideas, facts, information, and other public-domain material embodied in protected works” (including a restricted circumvention right).30 things change in two hundred-plus years, and the law must change with them. since the late nineteenth century, copyright law has been especially impacted by new technologies. the question is this: has copyright law struck the right balance between encouraging progress through granting creators specific rights and fostering a strong public domain that also nourishes creative endeavor? if that balance has been lost, how can it be restored? or is society simply no longer striving to maintain that balance because intellectual works are indeed property, property must be protected for commerce to prosper, and the concept of balance is outmoded and no longer reflects societal values? ฀ drm: locked-up content and fine-grained control noted attorney michael godwin defines drm as “a collective name for technologies that prevent you from using a copyrighted digital work beyond the degree to which the copyright owner (or a publisher who may not actually hold a copyright) wishes to allow you to use it.”31 like copyright, drm systems are complex, with many variations. there are two key technologies: (1) digital marking (i.e., digital fingerprints that uniquely identify a work based on its characteristics, simple labels that attach rights information to content, and watermarks that typically hide information that can be used to identify a work), and (2) encryption (i.e., scrambled digital content that requires a digital key to decipher it).32 specialized hardware can be used to restrict access as well, often in conjunction with digital marking and encryption. the intent of this article is not to provide a technical tutorial, but to set forth an overview of the basic drm concept and discuss its implications. what is of interest here is not how system a-b-c works in contrast to system x-y-z, but what drm allows copyright owners to do and the issues related to drm. to do so, let’s use an analogy, understanding that real drm systems can work in other ways as well (e.g., digital watermarks can be used to track illegal use of images on the internet without those images being otherwise protected). for the moment, let’s imagine that the content a user wishes to access is in an unbreakable, encrypted digital safe. the user cannot see inside the safe. by entering the correct digital combination, certain content becomes visible (or audible or both) in the safe. that content can then be utilized in specific ways (and only those ways), including, if permitted, leaving the safe. if a public domain work is put in the safe, access to it is restricted regardless of its copyright status. bill rosenblatt, bill trippe, and stephen mooney provide a very useful conceptual model of drm rights in their landmark drm book, digital rights management: business and technology, summarized here.33 there are three types of content rights: (1) render rights, (2) transport rights, and (3) derivative-works rights. render rights allow authorized users to view, play, and print protected content. transport rights allow authorized users to copy, move, and loan content (the user retains the content if it is copied and gets it back when a loan is over, but does not keep a copy if it is moved). derivative-works rights allow authorized users to extract pieces of content, edit the content in place, and embed content by extracting some of it and using it in other works. each one of these individual rights has three attributes: (1) consideration, (2) extents, and (3) types of users. in the first attribute, consideration, access to content is provided for something of value to the publisher (e.g., money or personal information). content can then be used to some extent (e.g., for a certain amount of time or a certain number of times). the rights and attributes users have are determined by their user types. digital dystopia | bailey 121 for example, an academic user, in consideration of a specified license payment by his or her library, can view a drm-protected scholarly article—but not copy, move, loan, extract, edit, or embed it—for a week, after which it is inaccessible. we can extend this hypothetical example by imagining that the library could pay higher license fees to gain more rights to the journal in question, and the library (or the user) could dynamically purchase additional article-specific rights enhancements as needed through micropayments. this example is extreme; however, it illustrates the fine-grained, high level of control that publishers could potentially have over content by using drm technology. godwin suggests that drm may inhibit a variety of legitimate uses of drm-protected information, such as access to public-domain works (or other works that would allow liberal use), preservation of works by libraries, creation of new derivative works, conduct of historical research, exercise of fair-use rights, and instructional use.34 the ability of blind (or otherwise disabled) users to employ assistive technologies may also be prevented by drm technology.35 drm also raises a variety of privacy concerns.36 fair use is an especially thorny problem. rosenblatt, trippe, and mooney state: fair use is an “i’ll know it when i see it” proposition, meaning that it can’t be proscriptively defined. . . . just as there is no such thing as a “black box” that determines whether broadcast material is or isn’t indecent, there is no such thing as a “black box” that can determine whether a given use of content qualifies as fair use or not. anything that can’t be proscriptively defined can’t be represented in a computer system.37 no need to panic about scholarly journals—yet. your scholarly journal publisher or other third-party supplier is unlikely to present you with such detailed options tomorrow. but you may already be licensing other digital content that is drm-protected, such as digital music or e-books that require a hardware e-book reader. as the recent sony bmg “rootkit” episode illustrated, creating effective, secure drm systems can be challenging, even for large corporations.38 again, the reasons for this are complex. in very simple terms, it boils down to this: assuming that the content can be protected up to the point it is placed in a drm system, the drm system has the best chance of working if all possible devices that can process its protected content either directly support its protection technology, recognize its restrictions and enforce them through another means, or refuse access.39 anything less creates “holes” in the protective drm shell, such as the well-known “analog hole” (e.g., when drm-protected digital content is converted to analog form to be played, it can then be rerecorded using digital equipment without drm protection).40 ideally, in other words, every server, network router, pc and pc component, operating system, and relevant electronic device (e.g., cd player, dvd player, audiorecording device, and video-recording device) would work with the drm system as outlined previously or would not allow access to the content at all. clearly, this ideal end-state for drm may well never be realized, especially given the troublesome backwardcompatibility equipment problem.41 however, this does not mean that the entertainment, information, and hightechnology companies will not try to make whatever piecemeal progress that they can in this area.42 the trusted computing group is an important multiple-industry security organization, whose standards work could have a strong impact on the future of drm. robert a. gehring notes: but a drm system is almost useless, that is from a content owner’s perspective, until it is deployed broadly. putting together cheap tc components with a marketdominating operating system “enriched” with drm functionality is the most economic way to provide the majority of users with “copyright boxes.”43 seth schoen argues computer owners should be empowered to override certain features of “trusted computing architecture” to address issues with “anti-competitive and anti-consumer behavior” and other problems.44 drm could potentially be legislatively mandated. there is a closely related legal precedent, the audio home recording act, which requires that digital audiotape equipment include special hardware to prevent serial copying.45 there is currently a bill before congress that would require use of a “broadcast flag” (a digital marker) for digital broadcast and satellite radio receivers.46 last year, a similar fcc regulation for broadcast digital television was struck down by a federal appeals court; consequently, the current bill explicitly empowers the fcc to “enforce ‘prohibitions against unauthorized copying and redistribution.’”47 another bill would plug the analog-to-digital video analog hole by putting “strict legal controls on any video analog to digital (a/d) convertors.”48 whether these bills become law or not, efforts to mandate drm are unlikely to end. dmca strongly supports drm by prohibiting both the circumvention of technological mechanisms that control access to copyrighted works (with some minor exceptions) and the “manufacture of any device, composition of any program, or offering of any service” to do so.49 what would the world be like if all newly published (or released) commercially created information was in digital form, protected by drm? what would it be like if all old works in print and analog formats were only reissued in digital form, protected by drm? what would it be like if all hardware that could process that digital information had to support the information’s drm scheme or block any access to it because this was mandated by law? what would it be 122 information technology and libraries | september 2006 like if all operating systems had direct or indirect built-in support for drm? would “progress of science and useful arts” be promoted or squashed? ฀ weaker net neutrality lessig identifies three important characteristics of the internet that have fostered innovation: (1) edge architecture: software applications run on servers connected to the network, rather than on the network itself, ensuring that the network itself does not have to be modified for new or updated applications to run; (2) no application optimization: a relatively simple, but effective, protocol is utilized (internet protocol) that is indifferent to what software applications run on top of it, again insulating the network from application changes; and (3) neutral platform: the network does not prefer certain data packets or deny certain packets access.50 lessig’s conceptual model is very useful when thinking about net neutrality, a topic of growing concern. educause’s definition of net neutrality aptly captures these concerns: “net neutrality” is the term used to describe the concept of keeping the internet open to all lawful content, information, applications, and equipment. there is increasing concern that the owners of the local broadband connections (usually either the cable or telephone company) may block or discriminate against certain internet users or applications in order to give an advantage to their own services. while the owners of the local network have a legitimate right to manage traffic on their network to prevent congestion, viruses, and so forth, network owners should not be able to block or degrade traffic based on the identity of the user or the type of application solely to favor their interests.51 for some time, there have been fears that net neutrality was endangered as the internet became increasingly commercialized, a greater percentage of home internet users migrated to broadband connections not regulated by common carrier laws, and telecommunications mergers (and vertical integration) accelerated. some of these fears are now appearing to be realized, albeit with resistance by the internet community. for example, aol has indicated that it will implement a two-tier e-mail system for companies, nonprofits, and others who send mass mailings: those who pay bypass spam filters, those who don’t pay don’t bypass spam filters.52 critics fear that free e-mail services will deteriorate under a two-tier system. facing fierce criticism from the dearaol.com coalition and many others, aol has relented somewhat on the nonprofit issue by offering special treatment for “qualified” nonprofits. a second example is that an analysis of verizon’s fcc filings reveals that “more than 80% of verizon’s current capacity is earmarked for carrying its service, while all other traffic jostles in the remainder.”53 content-oriented net companies are worried: leading net companies say that verizon’s actions could keep some rivals off the road. as consumers try to search google, buy books on amazon.com, or watch videos on yahoo!, they’ll all be trying to squeeze into the leftover lanes on verizon’s network. . . . “the bells have designed a broadband system that squeezes out the public internet in favor of services or content they want to provide,” says paul misener, vice-president for global policy at amazon.com.54 a third example is a comment by william l. smith, bellsouth ‘s chief technology officer, who “told reporters and analysts that an internet service provider such as his firm should be able, for example, to charge yahoo inc. for the opportunity to have its search site load faster than that of google inc.,” but qualified this assertion by indicating that “a pay-for-performance marketplace should be allowed to develop on top of a baseline service level that all content providers would enjoy.”55 about four months later, at&t announced that it would acquire bellsouth, after which it “will be the local carrier in 22 states covering more than half of the american population.”56 finally, in a white paper for public knowledge, john windhausen jr. states: this concern is not just theoretical—broadband network providers are taking advantage of their unregulated status. cable operators have barred consumers from using their cable modems for virtual private networks and home networking and blocked streaming video applications. telephone and wireless companies have blocked internet telephone (voip—voice over the internet protocol) traffic outright in order to protect their own telephone service revenues.57 these and similar examples are harbingers of troubled days ahead for net neutrality. the canary in the net neutrality mine isn’t dead yet, but it’s getting very nervous. the bottom line? noted oa advocate peter suber analyzes the situation as follows: but now cable and telecom companies want to discriminate, charge premium prices for premium service, and give second-rate service to everyone else. if we relax the principle of net neutrality, then isps could, if they wanted, limit the software and hardware you could connect to the net. they could charge you more if you send or receive more than a set number of emails. they could block emails containing certain keywords or emails from people or organizations they disliked, and block traffic to or from competitor web sites. they could make filtered service the default and force users to pay extra for the digital dystopia | bailey 123 wide open internet. if you tried to shop at a store that hasn’t paid them a kickback, they could steer you to a store that has. . . . if companies like at&t and verizon have their way, there will be two tiers of internet service: fast and expensive and slow and cheap (or cheaper). we unwealthy users—students, scholars, universities, and small publishers—wouldn't be forced offline, just forced into the slow lane. because the fast lane would reserve a chunk of bandwidth for the wealthy, the peons would crowd together in what remained, reducing service below current levels. new services starting in the slow lane wouldn't have a fighting chance against entrenched players in the fast lane. think about ebay in 1995, google in 1999, or skype in 2002 without the level playing field provided by network neutrality. or think about any oa journal or repository today.58 is net neutrality a quaint anachronism of the internet’s distant academic/research roots that we would be better off without? would new internet companies and noncommercial services prosper better if it was gone, spurring on new waves of innovation? would telecommunications companies (who may be part of larger conglomerates), free to charge for tiered-services, offer us exciting new service offerings and better, more reliable service? ฀ defending the internet revolution sixties icon bob dylan’s line in “the times they are achangin’”—“then you better start swimmin’ or you’ll sink like a stone”—couldn’t be more apt for those concerned with the issues outlined in this paper. here’s a brief overview of some of the strategies being used to defend the freewheeling internet revolution. 1. darknet: j. d. lasica says: “for the most part, the darknet is simply the underground internet. but there are many darknets: the millions of users trading files in the shady regions of usenet and internet relay chat; students who send songs and tv shows to each other using instant messaging services from aol, yahoo, and microsoft; city streets and college campuses where people copy, burn, and share physical media like cds; and the new breed of encrypted dark networks like freenet. . .”59 we may think of the darknet as simply fostering illegal file swapping by ordinary citizens, but the darknet strategy can also be used to escape government internet censorship, as is the case with freenet use in china.60 2. legislative and legal action: there have been attempts to pass laws to amend or reverse copyright and other laws resulting from the counter-internet-revolution, which have been met by swift, powerful, and generally effective opposition from entertainment companies and other parties affected by these proposed measures. the moral of this story is that these large corporations can afford to pay lobbyists, make campaign contributions, and otherwise exert significant influence over lawmakers, while, by and large, advocates for the other side do not have the same clout. the battle in the courts has been more of a mixed bag; however, there have been some notable defeats for reform advocates, especially in the copyright arena (e.g., eldred v. ashcroft), where most of the action has been. 3. market forces: when commercial choices can be made, users can vote with their pocketbooks about some internet changes. but, if monopoly forces are in play, such as having a single option for broadband access, the only other choice may be no service. however, as the oa movement (described later) has demonstrated, a concerted effort by highly motivated individuals and nonprofit organizations can establish viable new alternatives to commercial services that can change the rules of the game in some cases. companies can also explore radical new business models that may appear paradoxical to pre-internet-era thinking, but make perfect sense in the new digital reality. in the long run, the winners of the digital-content wars may be those who are not afraid of going down the internet rabbit hole. 4. creative commons: copyright is a two-edged sword: it can be used as the legal basis of licenses (and drm) to restrict and control digital information, or it can be used as the legal basis of licenses to permit liberal use of digital information. by using one of the six major creative common licenses (ccl), authors can retain copyright, but significantly enrich society’s collective cultural repository with works that can be freely shared for noncommercial purposes, used, in some cases, for commercial purposes, and used to easily build new derivative creative works. for example, the creative commons attribution license requires that a work is attributed to the author; however, a work can be used for any commercial or noncommercial purpose without permission, including creating derivative works.61 there are a variety of other licenses, such as the gnu free documentation license, that can be used for similar purposes.62 5. oa: scholars create certain types of information, such as journal articles, without expecting to be paid to do so, and it is in their best interests for these works to be widely read, especially by specialists in their fields.63 by putting e-prints (electronic preprints or post-prints) of articles on personal home pages or in various types of digital archives (e.g., institutional repositories) in full compliance with copyright law and, if needed, in compliance with publisher policies, scholars can provide free global access to these works with minimal effort and at no (or little) cost to themselves. further, a new generation of free e-journals are being published on the internet that are being funded by a variety of business models, such as advertising, author fees, library membership fees, and supplemental products. these oa strategies make digital 124 information technology and libraries | september 2006 scholarly information freely available to users across the globe, regardless of their personal affluence or the affluence of their affiliated institutions. ฀ impact on libraries this paper’s analysis of copyright, drm, and network neutrality trends holds no good news for libraries. copyright the reach of copyright law constantly encompasses new types of materials and for an ever-lengthening duration. as a result, copyright holders must explicitly place their works in the public domain if the public domain is to continue to grow. needless to say, the public domain is a primary source of materials that can be digitized without having to face a complex, potentially expensive, and sometimes hopeless permission clearance process. this process can be especially daunting for media works (such as films and video), even for the use of very short segments of these works. j. d. lasica recounts his effort to get permission to use short music and film segments in a personal video: five out of seven music companies declined; six out of seven movie studios declined, and the one that agreed had serious reservations.64 the replies to his inquiry, for those companies that bothered to reply at all, are well worth reading. for u.s. libraries without the resources to deal with complicated copyright-related issues, the digitization clock stops at 1922, the last year we can be sure that a work is in the public domain without checking its copyright status and getting permission if it is under copyright.65 what can we look forward to? lessig says: “thus, in the twenty years after the sonny bono act, while one million patents will pass into the public domain, zero copyrights will pass into the public domain by virtue of the expiration of a copyright term.”66 (the sonny bono term extension act was passed in 1998.) digital preservation is another area of concern in a legal environment where most information is automatically copyrighted, copyright terms are lengthy (or endless), and information is increasingly licensed. simply put, a library cannot digitally preserve what it does not own unless the work is in the public domain, the work’s license permits it, or the work’s copyright owner grants permission to do so. or can it? after all, the internet archive does not ask permission ahead of time before preserving the entire internet, although it responds to requests to restrict information. and that is why the internet archive is currently being sued by healthcare advocates, which says that it: “is just like a big vacuum cleaner, sucking up information and making it available.”67 if it is not settled out of court, this will be an interesting case for more digitally adventurous libraries to watch. as the cost of the hardware and software needed to effectively do so continues to drop, faculty, students, and other library users will increasingly want to repurpose content, digitizing conventional print and media materials, remixing digital ones, and/or creating new digital materials from both. with the “information commons” movement, academic libraries are increasingly providing users with the hardware and software tools to repurpose content. given that the wording of the u.s. copyright act section 108 (f) (1) is vague enough that it could be interpreted to include these tools when they are used for information reproduction, is the old “copyright disclaimer on the photocopier” solution enough in the new digital environment? or—in light of the unprecedented transformational power of these tools to create new digital works, and their widespread use both within libraries and on campus—do academic libraries bear heavier responsibilities regarding copyright compliance, permission-seeking, and education? similar issues arise when faculty want to place self-created digital works that incorporate copyrighted materials in electronic reserves systems or institutional repositories. enduser contributions to “library 2.0” systems that incorporate copyrighted materials may also raise copyright concerns. drm as libraries realize that they cannot afford dual formats, their new journal and index holdings are increasingly solely digital. libraries are also licensing a growing variety of “born digital” information. the complexities of dealing with license restrictions for these commercial digital products are well understood, but imagine if drm was layered on top of license restrictions. as we have discussed, drm will allow content producers and distributors to slice, dice, and monetize access to digital information in ways that were previously impossible. what may be every publisher/vendor’s dream could be every library’s nightmare. aside from a potential surge of publisher/vendor-specific access licensing options and fees, libraries may also have to contend with publisher/ vendor-specific drm technical solutions, which may: ฀ depend on particular hardware/software platforms, ฀ be incompatible with each other, ฀ decrease computer reliability and security, ฀ eliminate fair or otherwise legal use of drm-protected information, ฀ raise user privacy issues, ฀ restrict digital preservation to bitstream preservation (if allowed by license), digital dystopia | bailey 125 ฀ make it difficult to assess whether to license drmprotected materials, ฀ increase the difficulty of providing unified access to information from different publishers and vendors, ฀ multiply user support headaches, and ฀ necessitate increased staffing. drm makes solving many of these problems both legally and technically impossible. for example, under dmca, libraries have the right to circumvent drm for a work in order to evaluate whether they want to purchase it. however, they cannot do so without the software tools to crack the work’s drm protection. but the distribution of those tools is illegal under dmca, and local development of such tools is likely to be prohibitively complex and expensive.68 fostering alternatives to restrictive copyright and drm given the uphill battle in the courts and legislatures, ccls (or similar licenses) and oa are particularly promising strategies to deal with copyright and drm issues. copyright laws do not need to change for these strategies to be effective. it is not just a question of libraries helping to support oa by paying for institutional memberships to oa journals, building and maintaining institutional repositories, supporting oa mandates, encouraging faculty to edit and publish oa journals, educating faculty about copyright and oa issues, and encouraging them to utilize ccls (or similar licenses). to truly create change, libraries need to “walk the talk” and either let the public-domain materials they digitize remain in the public domain, or put them under ccls (or similar licenses), and, when they create original digital content, put it under ccls (or similar) licenses as well. as the oa movement has shown, using ccls does not rule out revenue generation (if that is an appropriate goal), but it does require facilitating strategies, such as advertising and offering fee-based add-on products and services. net neutrality there are many unknowns surrounding the issue of net neutrality, but what is clear is that it is under assault. it is also clear that internet services are more likely to require more, not less, bandwidth in the future as digital media and other high-bandwidth applications become more commonplace, complex, and interwoven into a larger number of internet systems. one would imagine that if a corporation such as google had to pay for a high-speed digital lane, it would want it to reach as many consumers as possible. so, it may well be that libraries’ google access would be unaffected or possibly improved by a two-tier (or multi-tier) internet “speed-lane” service model. would the same be true for library-oriented publishers and vendors? that may depend on their size and relative affluence. if so, the ability of smaller publishers and vendors to offer innovative bandwidth-intensive products and services may be curtailed. unless they are affluent, libraries may also find that they are confined to slower internet speed lanes when they act as information providers. for libraries engaged in digital library, electronic publishing, and institutional repository projects, this may be problematic, especially as they increasingly add more digital media, large-data-set, or other bandwidth-intensive applications. it’s important to keep in mind that net neutrality impacts are tied to where the chokepoints are, with the most serious potential impacts being at chokepoints that affect large numbers of users, such as local isps that are part of large corporations, national/international backbone networks, and major internet information services (e.g.,yahoo!). it is also important to realize that the problem may be partitioned to particular network segments. for example, on-campus network users may not experience any speed issues associated with the delivery of bandwidth-intensive information from local library servers because that network segment is under university control. remote users, however, including affiliated home users, may experience throttled-down performance beyond what would normally be expected due to speed-lane enforcement by backbone providers or local isps controlled by large corporations. likewise, users at two universities connected by a special research network may experience no issues related to accessing the other university’s bandwidth-intensive library applications from on-campus computers because the backbone provider is under a contractual obligation to deliver specific network performance levels. although the example of speed lanes has been used in this examination of potential net neutrality impacts on libraries, the problem is more complex than this, because network services, such as peer-to-peer networking protocols, can be completely blocked, digital information can be blocked or filtered, and other types of fine-grained network control can be exerted. ฀ conclusion this paper has deliberately presented one side of the story. it should not be construed as saying that copyright law should be abolished or violated, that drm can serve no useful purpose (if it is possible to fix certain critical deficiencies and if it is properly employed), or that no one has to foot the bill for content creation/marketing/distribution and ever-more-bandwidth-hungry internet applications. 126 information technology and libraries | september 2006 nor is it to say that the other side of the story, the side most likely to be told by spokespersons of the entertainment, information, and telecommunications industries, has no validity and does not deserve to be heard. however, that side of the story is having no problem being heard, especially in the halls of congress. the side of the story presented in this paper is not as widely heard—at least, not yet. nor does it intend to imply that executives from the entertainment, information, telecommunications, and other corporate venues lack a social conscience, are fully unified in their views, or are unconcerned with the societal implications of their positions. however, by focusing on short-term issues, they may not fully realize the potentially negative, long-term impact that their positions may have on their own enterprises. nor has this paper presented all of the issues that threaten the internet, such as assaults on privacy, increasingly determined (and malicious) hacking, state and other censorship, and the seemingly insolvable problem of overlaying national laws on a global digital medium. what this paper has said is simply this: three issues—a dramatic expansion of the scope, duration, and punitive nature of copyright laws; the ability of drm to lock-down content in an unprecedented fashion; and the erosion of net neutrality—bear careful scrutiny by those who believe that the internet has fostered (and will continue to foster) a digital revolution that has resulted in an extraordinary explosion of innovation, creativity, and information dissemination. these issues may well determine whether the much-touted information superhighway lives up to its promise or simply becomes the “information toll road” of the future, ironically resembling the pre-internet online services of the past. references and notes 1. gary flake, “how i learned to stop worrying and love the imminent internet singularity,” http://castingwords.com/ transcripts/o3/5073.html (accessed may 2, 2006). 2.

2. are difficult to implement; 3. really aren't democratic; 4. are basically polling devices. it has been said that the reason that railroads went out of business was because they insisted that they were in the railroad business and wouldn't admit that they were in the transportation business . if cable operators insist that they are in the television business, they may well miss the opportunities that are possible in the communications business or, in fact, in the information business . by the same token, if libraries miss the significance of what cable television is bringing to their business, their role in the community will be diminished and libraries may go the way of railroads. modern communications and computers offer an opportunity for libraries to become the information choice in their community. in the near future, applications such as the home book club may well be a way to provide increased accessibility of library services to library patrons, and to "condition" those patrons to the coming electronic nature of libraries. over the long term, libraries, if they have the courage and the foresight, can be the focus of the coming information and telecommunications revolution . the message is quite clear: opportunities abound. references l. john wicklein, "wired city, u.s.a: the charms and dangers of two-way tv," atlantic monthly 243:35--42 (feb. 1979). 2. warner amex represents a newly formed corporation resulting from the merger of warner communications and american express. 3. jonathan black, "brave new world of television," new times 11:41 (24 july 1978). 4. ibid ., p.49. 5.

(cti), * for use when the clsi libs 100 automated circulation system is not operating, great neck library conducted an informal survey of libraries using both systems . eleven institutions, including both public and academic libraries , responded to a brief questionnaire. they were asked what size cti system they had purchased and why, how easily it was installed, how well it performed, how it was maintained, and if clsi acknowledged that the addition of the backup did not affect their libs 100 maintenance agreements . before summarizing the responses, the structure of the two systems and how they interact should be outlined. clsi libs 100 the clsi automated circulation system consists of a stand-alone minicomputer console with local and/or remote terminals connected to it through individual ports by means of electrical and/or dedicated telephone line hookups . when it operates, the terminals are online and interactive with the database, which is stored on one or more multiplatter disc packs. cti backup the cti backup system is based on an apple ii microcomputer with two minidisc drives, which take 51/.-inch floppy discs, a tv monitor, and a switching system that can be connected to the libs 100 console or its terminals. the cti system can also be used alone . when the libs 100 is down (inoperative), the cti system is connected to a terminal, and data is recorded on its discs for later dumping (data entry) into the database via a port connection . it *cti is a profit-making company wholly owned by brigham young university. the cti backup system was originally developed to support the clsi-installation at byu. appears to the public and the library's staff memb e r operating the backup-terminal combination that the terminal is working. there is, however, no connection between the backup unit and the database in this mode. when the libs 100 is up (operating) once again, the backup is connected and data is automatically dumped. naturally the port cannot be used by both the clsi terminal and the backup unit at the same time without the addition of other hardware . the terminals attached to other ports may operate normally while dumping is completed. the clsi and cti software, which operate compatibly, are owned by the respective companies, not the library . the responses 1. size of system : cti systems are available in two sizes , 32k and 48k . two libraries purchased the smaller system, nine purchased the larger system, and one purchased both. greater programming capabilities of the larger system were consid e red its greatest asset. 2. reason for purchase: five libraries indicated they use the backup for other purposes in addition to substituting for the libs 100 when it is down . among these other purposes were development of a community information database, personnel and financial reports and files, use as an rlin terminal, as a bookmobile terminal, and as an aid in converting short-title bibliographic records to expanded format. 3. installation: respondents were unanimous in having no problems with installation . seven did their own installation, while cti gave instructions over the phone. three were installed by cti, who also trained the library staff in its operation. one library indicated the accompanying documentation was enough to install the system without assistance. 4. performance: all eleven respondents were enthusiastic about system performance. some comments were, "it's the best thing since buttered communications 109 popcorn," and "we love it dearly 0 0 0 0 it saves hours 0 0 0 works just fine . " many commented on the slow dumping time as the biggest drawback, but noted that increased accuracy over manual entry and decreased pressure on their circulation staff during downtime were assets. 5. maintenance: backup system maintenance is not uniform . six respondents said that software was maintained by cti, but hardware was maintained by an apple dealer; or they were undecided about who would be respons ible for hardware repairs. a seventh library contracted with an apple dealer for hardware repairs, but was contending over software mai ntenance with ct i. three libraries answered that cti was maintaining the system, but did not specify both hardware and software . the last respondent expected to take hardware repairs to an apple dealer and did not mention software . 6. clsi maintenance agreements: one library stated that they had written assurance from clsi that the installation of the backup system would not affect their libs 100 maintenance contract. three more said they had verbal assurances . five respondents indicated no assurances from clsi that the libs 100 contract was not affected . one library sent a copy of a clsi · letter defining company policy in this area. it said, in part: "clsi does not prohibit the attachment of foreign devices to the systems . .. . " qualifications to this statement involved an inst itution's attempt to repair the libs 100 itself, to hold clsi responsible for damage resulting from the attachment of the device, or to have clsi maintain the device . the great neck library decided to purchase two cti backup systems for use when the libs 100 is down. experience bears out the findings of the survey ; i.e . , it is easy to install the system with only telephone assistance; it works well, and, though data transmission to the main unit is slow, it is accurate and removes some of llo journal of library automation vol. 14/2 june 1981 the desperation from a downtime situation. great neck library is also planning to use the apples for other functions, which, it is hoped, will be implemented soon . multimedia catalog: com and online kenneth j. bierman: tucson public library, tucson, arizona. like many public libraries, the tucson public library (tpl) is closing its card catalog and implementing a vendorsupplied microform catalog. unlike most of these other libraries, however, the tpl microform catalog will not include: location or holding information. the indication of where copies of a particular title are actually available (i.e., which of the fifteen possible branch locations) will be available only by accessing a video display terminal connected to the online circulation and inventory control system. conceptually, the tpl catalog will be in two parts with each part intended to serve different functions . 1 the microform catalog (copies available in both film and fiche format) will fulfill the bibliographic function of the catalog. this catalog will contain bibliographic description and provide the traditional access points of author, title, and subject. the online catalog (online terminals are in place at all reference desks and a few public access terminals will also be available) will fulfill the finding or locating function of the catalog. this catalog will contain very brief bibliographic description and will only be searchable by author, title, author/title, and call number, and will contain the current status of every copy of every title in the library system (i.e., on shelf, checked out, at bindery , reported missing, etc.). why did the tucson public library make this decision? there are two major reasons: l. accuracy . the location information , if provided in the microform catalog, would always be inaccurate and out of date. assuming that the locations listed in the latest edition of the microform catalog were completely accurate when the catalog was first issued (an unrealistic assumption to begin with as anyone who has ever worked with location information at a public library with many branches well knows!), the location information would become increasingly less accurate with each day because of the large number of withdrawals, transfers, and added copy transactions that occur (more than 100 , 000 a year). in addition, at any given time, one-quarter to one-third of the materials in busy branches are not on the shelf because they are either checked out or waiting to be reshelved. thus, the microform catalog would indicate that these materials were available at specific branches when a significant percentage would in fact not be available at any given time. in short, even in the best of circumstances, easily half of the location information would be incorrect in telling a user where a copy of a title was actually available at that moment. 2 . cost . a study done at the tucson public library indicated that close to half of the staff time of the cataloging department was spent dealing with location and holding information. this time includes handling transfers, withdrawals, and added copies. all of this record keeping is already being done as a part of the online circulation and inventory control system (the tucson public library has no card shelflist containing copy and location information but rather relies completely on the online file for this type of information) . to "duplicate" the information in the microform catalog would cost an estimated $40,000 to $60,000 a year and the information in the microform catalog would never be accurate or up to date for the reasons outlined above. figure 1 is a brief summary of how the bibliographic system will work. would the system in figure 1 be improved if holdings were included in the microform catalog? on the surface, the obvious answer is yes-more information is editorial board thoughts drained-pool politics versus digital libraries in u.s. cyberspace mary a. guillory, mlis information technology and libraries | december 2023 https://doi.org/10.5860/ital.v42i4.16988 about the author mary a. guillory (corresponding author:

board as a whole or of core, a division of ala. u.s. libraries in cyberspace are suffering from and combatting a series of actions and campaigns that aim to eliminate them rather than allocate mental bandwidth for diverse titles—in other words, digital libraries are dealing with modern-day drained-pool politics. as public, school, and university libraries become increasingly digital, the ability to simply switch off the entire library becomes more of a threat. with the internet being both literacy’s greatest enemy (it represents a single point of failure) and ally (it has been almost universally adopted), volume of access, money, and grey area legislation often play a large role in intellectual freedom. book banning—a naturally polarizing issue—has not yet found balance when it comes to books, magazines, audiobooks, movies, and music within digital libraries. though the capability to ban one book exists as it does in the physical world, access to digital libraries has become all-or-nothing in many instances around the nation. there is no consistency of approach across states, municipalities, or even school districts, with federal law applying only on a case-by-case basis. for example, brevard public schools in florida caused a stir last year when access to epic, the digital library software students had become accustomed to for leisurely family reading time, mysteriously disappeared.1 the school district cited an inability to comply with a new state law that requires all instructional material available in the digital library to be reviewed. while this loss of access primarily affected students under the age of 12 attending schools in the district, digital library bans have a way of expanding into the adult age group and the general public who may be receiving an entirely different type of education. in july 2023, mississippi state law essentially barred everyone under the age of 18 from the hoopla and overdrive digital libraries.2 in texas, patrons of the llano county library system—adults included—celebrated a small victory by having a federal judge restore some digital library access and the local government decide against the retaliatory closure of the libraries who filed the suit.3 when it comes to mass media, the category digital libraries belong to, there is a fine line between telling the stories of the people who make the world go round and promoting an idea or way of life. the realities of society can’t be treated as elephants in a room, when they are in fact the shared experiences of communities hiding in plain sight to avoid ostracism. that is, these are not stories that everyone knows about and refuses to acknowledge, but stories that people who most need to make a connection or understand a different viewpoint may never know exist. as the world depicted in fahrenheit 451 becomes closer to reality, there are both current tools in place and rebalancing efforts emerging. in september of this year, california took the opposite approach of texas and florida when its governor banned book bans in schools with state law.4 the bill was signed just months after https://www.linkedin.com/in/maryaguillory/ information technology and libraries december 2023 editorial board thoughts 2 guillory access to the sora digital library was taken away from orange unified school district students and families.5 many public libraries in the state of california already operate under a “universal borrower” policy that allows state residents to obtain a library card at any library, which provides access to a multitude of digital library materials. in georgia, a similar budding program exists. public libraries participating in the pines program allow residents to obtain cards at any participating library within the state. these preexisting tools facilitating access help to keep the intellectual freedom scale stable while newer programs hope to rebalance a tilting scale. some libraries and literacy organizations are taking a direct and national stand against book bans by opening their digital libraries nationwide to provide access to those who should be intellectually free. the brooklyn public library launched its books unbanned program to provide digital library access nation-wide to teens and young adults within the 13–21 age range.6 the program has grown with the boston public library, la county public library, san diego public library, and seattle public library all offering a variation. the digital public library of america’s banned book club created an entire digital library consisting of books that had been banned “somewhere.”7 broader legislation is needed to protect access to the truth, access to reality, and access to viewpoints sidelined by aggressive idealism. digital libraries are a melting pot for all the diverse people and experiences that make up the world. a story that is hard to hear is not a story that is wrong to listen to; writers are supposed to elicit emotion to help readers spend some time in someone else’s shoes. to learn more about this multifaceted issue, visit the american library association’s

migration/redesign, and a new catalog discovery layer. we considered bibliocommons as the vendor for both projects. they offer both a website product (biblioweb) and a discovery layer (bibliocore). we opted to complete the website migration/redesign ourselves using open source software, migrating from our previous drupal 7 platform to drupal 8, and to contract with bibliocommons to provide our new discovery layer. this put us in an unusual position. we were implementing a website migration/redesign ourselves while simultaneously working with the vendor we would likely have chosen for the website project on the catalog discovery layer. this gave us the opportunity to compare the experience of implementing the website project ourselves with what the same project might have been like if we had been working with a vendor. what we learned timing not surprisingly, completing the website project on our own took longer than expected. • learning curve—we expected there to be a learning curve but it turned out to be significantly steeper than anticipated. • unknowns—in addition to basic learning, we also came across functionality that didn’t work as expected. • failures—there were times when what we tried to do didn’t work at all and we had to backtrack. timing for the vendor-led project, on the other hand, kept to the planned timeline. • prescribed timeline—as part of their contract, the vendor provided a timeline at the outset. we made small adjustments but for the most part the project stayed on time. • predictability—the vendor has completed many similar projects so they had a solid idea what to expect and how long it would take. • problem solving—some challenges unique to our situation did arise and caused some delays. control the ability to have more control over the project results was a significant factor in our decision to complete the website project ourselves. we had the opportunity to make choices and also faced the challenge of a sometimes-overwhelming number of options. mailto:laurie.willis@sjlibrary.org information technology and libraries march 2020 tackling the big projects | willis 2 • options—many options were available to us. we had choices regarding structure (website platform and theme), design and content. • overwhelm the plethora of options encouraged a tendency to spend a lot of time (too much?) “shopping”—researching and evaluating options. • we completed a thorough audit of our content and created a new site based on our needs. • user experience (ux) testing—we were able to perform testing with our users and adapt our website to better fit their needs. working with a vendor, on the other hand, limited what we were able to do but the decision -making process was easier and faster. • we had the option to select colors but otherwise the structure and design were fixed. • we had some control over textual content within the parameters given. e.g. we could add links to the footer but the number of links allowed was limited. • little time was spend making these decisions. • it’s a challenge fitting unique content into a pre-determined format. • user experience (ux) testing—the vendor is able to include a wider sampling of people while testing, but they’re not able to specifically consider our local users. implementation for the website project, implementation turned out to be more complex than expected. • learning—as mentioned above, there were many new things to learn that came up as the project progressed. • consultant—we came up with technical questions that were beyond the scope of our knowledge. we found it extremely helpful to contract with a consultant for guidance. • conflicting responsibilities—we worked on this project while continuing with our normal workload and maintaining the current website. we were also simultaneously working on the discovery layer implementation. the vendor-led implementation went more smoothly. • learning—the vendor assigned a project manager, who was available to guide us through the process. the vendor also provided documentation that walked us through the process. • expertise—when challenges did arise, the vendor had an experienced staff to help us work through them. • staff time—although the vendor did most of the work, the project did consume significantly more staff time than expected as we worked through every detail. training and marketing • staff for the website, we had to create our own training for staff. for the catalog, the vendor offered webinars for staff and sent a trainer to do in-person training. • public the vendor offered samples of materials from other libraries to both inform and educated the public. since both projects were launching at the same time, we were able to adapt some of these materials to include both. cost the cost of hiring a vendor initially seems steep, but staff time is also expensive. considering the unexpected additional staff time spent, it likely would have been less expensive to choose the vendor option. information technology and libraries march 2020 tackling the big projects | willis 3 conclusion there are pros and cons to both methods—completing a project on your own or working with a vendor. whether your project is a new website or catalog or something else entirely, learn as much as you can about what will be involved before you decide on an approach. weigh your options by looking at your needs and the resources and time available to you. the primary aspects to consider are: • do staff have the necessary expertise to complete the project? will there be a learning curve? are staff prepared and willing to learn new things and figure things out? if you are considering a vendor, do they have a training plan for • how much time is available? is there a deadline? if there is a deadline, what will be the costs if it needs to be extended? if you are considering a vendor, how committed are they to achieving the prescribed deadline? • which is more important to you—control and flexibility or ease of implementation? • what resources are available if you have questions? if you work on your own, are there people and online resources you will be able to turn to? if you are considering a vendor, will you be assigned a representative to walk you through the process? for our particular situation, i believe we made the right choice to complete the website project on our own. staff had enough expertise that they were willing and able to learn the necessary skills, calling upon a consultant when needed without outsourcing the entire project. while we had an expected timeline, we were able to extend it with only minor consequences (paying for additional web hosting while the project was under construction.) we maintained the control and flexibility we needed in order to present some of the unique services and spaces that our library offers, which might have been lost using a vendor package. we had some knowledge of consultants working in the field and were able to hire one to show us how to proceed when we were over our heads. we also relied heavily on tutorials and other training resources posted online. whatever you decide, taking time to think things through before beginning will help make your project a success. what we learned timing control implementation training and marketing cost conclusion

abstract contactless services have become a common way for public libraries to provide services. as a result, the strategy used by public libraries in china will effectively stop the spread of epidemics caused by human touch and will serve as a model for other libraries throughout the world. the primary goal of this study is to gain a deeper understanding of the contactless service measures provided by large chinese public libraries for users in the pandemic era, as well as the challenges and countermeasures for providing such services. the data for this study was obtained using a combination of website investigation, content analysis, and telephone interviews for an analytical survey study of 128 large public libraries in china. the study finds that touch-free information dissemination, remote resources use, no-touch interaction self-services, network services, online reference, and smart services without personal interactions are among the contactless services available in chinese public libraries. exploring the current state of contactless services in large public libraries in china will help to fill a need for empirical attention to contactless services in libraries and the public sector. up-to-date information to assist libraries all over the world in improving their contactless services implementation and practices is provided. introduction the spread of covid-19 began in 2020, and people all over the world are still fighting the severity of its spread, the breadth of its impact, and the extent of its endurance. the virus’s continued spread has had a wide-ranging impact on industry sectors worldwide, including libraries. the growth of public libraries has also seen significant changes as a result of covid-19, resulting in added patron services, including contactless services. contactless services are those that patrons can use without having to interact face to face with librarians. these services transcend time and geographical constraints, as well as lower the danger of disease transmission through human interaction. since the covid-19 pandemic, contactless or touch-free interaction services are emerging in chinese public libraries. this service model can also serve as a reference for other libraries. this study evaluates and analyzes contactless service patterns in large public libraries in china, and then suggests a contactless service framework for public libraries, which is currently in the process of being implemented. mailto:yadon0619@hotmail.com mailto:yangzinan612@163.com mailto:mahuifang126@126.com mailto:liuy1@southernct.edu information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 3 literature review the available literature shows that the term “non-contact” appeared as early as 1916 in the article “identification of the meningococcus in the naso-pharynx with special reference to serological reactions” and described a patient’s infection in the context of medical research.1 in recent years, with the widespread application of “internet +” and the development and promotion of technologies such as the internet of things, cloud computing, and artificial intelligence, the contactless economy has grown by leaps and bounds, and so has the research on library contactless services.2 library contactless services encompass a wide range of services such as selfservices, online reference, and smart services without personal interactions. library self-service has become a major service model for contact-free services. the self-service model was first adopted in american public libraries in the 1970s with the emergence of self service borrowing and returning practices.3 many public libraries have since adopted stand-alone, fully automated self-service halls, self-service counters, etc.4 by the 1990s, a range of commercial self-service kiosks and self-service products had been introduced.5 currently, the most mature self-service type used by the library community is the circulation self-service product.6 in addition to self-service borrowing and returning of titles, libraries have launched self-service printing systems, self-service computer systems, and self-service booking of study spaces.7 as an example, patrons can complete printing operations using a self-service system and can offer payment by bank card, alipay, wechat, and other means.8 a face recognition system can also be used to borrow and return books, a solution for patrons who forget their library cards.9 these library selfservice system elements are confined to simple, repetitive, and routine tasks such as conducting book inventories, book handling, circulating books, and the like, whose development stems from the widespread application of electronic magnetic stripe technology and radio frequency identification (rfid), optical character recognition (ocr) technology, and face recognition.10 new applications of technology continue to advance the development of contactless services in libraries. the overall work and service processes of the library have been made intelligent to varying degrees. online reference is an important service in the contactless service program. researchers have started to study the current state of library reference services. interactive online reference services support patrons using the library, including how to search for literature, locate and renew books, schedule a study or seminar room, and participate in other library activities, such as seminars, lectures, etc.11 in response to the problem of how patrons access various library service abilities, digital reference systems need to have functions such as automated semantic processing, automated scene awareness, through automatic calculation and adaptive matching, understanding of patrons’ interests preferences and needs, and the ability to recommend the most suitable information resources for them.12 at present, most library reference services in china mainly include the use of telephone, email, wechat, robot librarians/interactive communication, microblogs, and qq, an instant messaging software popular in china. during the past two years, most public libraries in china have essentially implemented the use of the aforementioned reference tools to communicate and interact with patrons, with wechat having a 55.6% adoption rate when compared to other instant reference tools.13 the use of online chat in reference services has allowed librarians to help patrons from anywhere and at any time through embedding chat plug-ins into multiple pages of the library website and directing patrons to ask questions based on the specific page they are viewing, setting up automatic pop-up chat windows, and changing patrons’ passive waiting to active engagement. 14 in terms of technology, emerging technologies information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 4 such as patron profiling, natural language processing, and contextual awareness can support the development of reference advisory services in libraries.15 the online reference service provides a 24/7, high-quality, efficient, and personalized service that connects libraries more closely with society and is an important window in the future smart library service system. smart services without personal interactions may become the most popular form of library services development for the future, and research on library smart services has gradually deepened. in terms of conceptual definition, the library community generally understands the concept of library smart services as mobile library services that are not limited by time and space and can help patrons find books and other types of materials in the library by connecting to the wireless internet.16 apart from this, there are two other ways to define library smart services. one discusses the meaning of smart services in an abstract way, such as library smart services that should be an advanced library form dedicated to knowledge services through human-computer interaction, a comprehensive ecosystem.17 the other concretizes the extension of this concept expressed with a formula “smart library = library + internet of things + cloud computing + smar t devices.”18 applied technology research is an important part of smart services in libraries. library smart services have three main features: digitization, networking, and clustering. among them, digitization provides the technical basis, networking provides the information guarantee, and clustering provides the library management model of resources sharing, complementary advantages, and common development among libraries.19 the key breakthrough in the development of smart services is the applications deployment of smart technologies to truly realize a new form of integration of online and offline, virtual and reality. 20 the integration of face recognition technology in traditional libraries, as well as its application to services like acces s control management, book borrowing and returning, and wallet payment, can help libraries build smart services faster.21 the integration of deep learning into a mobile visual search system for library smart services can play an important role in integrating multiple sources of heterogeneous visual data and the personalized preferences of patrons.22 blockchain technology, born out of the impact of the new wave of information technology, has also been applied to the construction of smart library information systems because of its decentralized and secure features.23 library smart services can leverage new technologies and smart devices to enhance the efficiency of library contact-free services and provide new opportunities for knowledge innovation, knowledge sharing, and universal participation, thereby enabling innovation in service models. additional research on the development of contactless services in service areas such as library self-services, online reference, and smart services is discussed. in particular, the research and construction of smart library services have been enriched with the advent of big data and artificial intelligence. however, non-contact service has not been systematically researched and elaborated in domestic and international librarianship. the emergence and prevalence of covid-19 has enabled libraries in many countries to practice various types of touch-free services, such as the introduction of postal delivery, storage deposit, and click-and-collect in australian libraries; curbside pickup service or build a book bag service in us public libraries; and delivery book to the building services in chinese university libraries. 24 therefore, a systematic investigation and study of contactless services in public libraries in the pandemic is of great importance for the adaptation and innovation of library services. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 5 methods survey samples the survey selected some of the most typical public libraries for the study. the selection criteria were those large public libraries in the more economically and culturally developed regions of china. a total of 128 large public libraries were identified, including national libraries, 32 provincial public libraries, and municipal public libraries in the top 100 cities by gdp ranking in 2020, of which five public libraries, including the capital library and nanjing library, are both top 100 city libraries and provincial libraries. these 128 large public libraries can more obviously reflect the current service level of the better developed public libraries in china, and represent the highest level of public library construction in china.

and interviews with librarians were used to assess 128 public libraries in china. the survey was carried out between march 10 and september 15 in 2021. first, the authors identified the media platforms for sharing information about each public library’s contactless services, including an official website, a social networking account on wechat, or a library-developed app. the authors investigated whether these media platforms were updated with information about the contactless services and if they provided various information about these services. next, the authors searched the various contactless services offered by this library through these media platforms and recorded them. finally, the authors reviewed the data and findings from the survey to minimize errors and ensure the accuracy of the findings. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 7 findings touch-free information distribution the distribution of library information is generally carried out in a touch-free manner. there are three commonly used information media in libraries: official website, wechat official account, and library-developed app. the adoption rate of each information medium by libraries is determined by investigating whether libraries have opened information media platforms and whether the opened platforms are updated with service information. the results showed that the information medium with the highest adoption rate was the wechat official account, reaching 100%. the library’s official website showed an adoption rate of 94%. only 57% of libraries use apps to distribute contactless information (see fig, 1). figure 1. percentage of touch-free information distribution platforms in large public libraries in china. patron services must provide timely and convenient access if public libraries want to effectively expand their patron base or increase library usage. wechat is better adapted to user convenience than websites, which explains the greater utilization rate as a contactless information dissemination tool for libraries. as a public service institution, the chinese public library has an incomparable impact on politics, economy, and culture. libraries have a great influence on the cultural popularization and educational development of the public. therefore, touch-free information dissemination plays an important role in improving the efficiency of information dissemination. wechat has been fully integrated into china’s public library services as a communication tool, allowing libraries to better foster cultural growth. in the process of cultural growth, libraries need to emphasize interactive public participation and combine public culture, social topics, citizen interaction and media communication, bringing innovative value to promote urban vitality and urban humanism. the 100% 94% 57% 0% 20% 40% 60% 80% 100% 120% wechat official account official website app information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 8 widespread use of wechat helps users stay up to date on the newest information and access library resources services more conveniently. remote resources services restrictions on the use of digital resources are closely related to the frequency of patrons’ use. restrictive measures that posed obstacles to patrons using digital resources were identified. among the 128 large public libraries surveyed, 42% of libraries require reader card authentication by patrons before they can access remote resources services; 8% of libraries do not require users to have reader cards for services. patrons can use the remote resources services available in the remaining 49% of public libraries without needing to register for a user account or patron id on the library website. to reduce the risk of infection between librarians and patrons, some libraries adopted noncontact paper document delivery services for users in urgent need of paper books during the pandemic. for example, the peking university library’s book delivery to building service (see fig. 2) and xiamen library and wenzhou library’s book delivery to home (see fig. 3) allow patrons to reserve books online, and librarians will express mail the books to patrons’ homes according to their needs. figure 2. peking university library’s book delivery service to the building. figure 3. book delivery service of xiamen library and wenzhou library. contactless services have two outstanding advantages: services can be obtained without contact with people, and convenience. however, if the use of remote resources is restricted in many ways, it will lead to a decrease in the utilization of digital resources in libraries. while intellectual property requirements and concerns must be appropriately managed, public libraries should strive to provide patrons with unlimited access to digital materials and physical print books. no-touch interaction self-services no-touch interaction self-services in chinese public libraries mainly include self-checkout, selfretrieval, self-storage, self-printing, self-card registration, and other self-service services, such as self-payment, and self-reservation of study rooms or seminar rooms (see fig. 4). information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 9 figure 4. percentage of large public libraries in china that provide contactless self-service. the survey of large public libraries in china shows that the majority offer self-checkout and selfretrieval services. the percentage of public libraries offering self-storage, self-certification and self-printing is low, with only 50% or less usage. self-storage, as one of the earlier self-services, has a usage rate of 50%. only 34 percent of public libraries offered self-card registration. the selfservice card registration machine has four main functions: reader card registration, payment, password modification, and renewal. for example, when patrons need to pay deposits or overdue fines, they can use the self-service card registration machine to swipe their cards and payment to facilitate subsequent borrowing of various resources. the machine supports face recognition technology for card application and online deposit recharge, catering to the needs of patrons in many aspects of operation (see fig. 5). the proportion of self-printing is even lower available at only 15% of libraries. self-card registration and self-printing are both emerging self-service options that require strong financial and technical support and are therefore not widely available. 5% 99% 98% 50% 34% 15% 0% 20% 40% 60% 80% 100% 120% others

self-service card registration machine in chinese large public libraries. most public libraries in china have set up dedicated self-service libraries or microservice halls on the wechat public account platform in addition to further promoting library contactless services and enabling users to enjoy self-service library services anytime, anywhere. for example, the changsha library (see fig. 6) and the taiyuan library (see fig. 7) have both set up a microservice hall column on their wechat public numbers, containing services such as personal appointment, book renewal, event registration, and digital resources. the emergence of online self -service library services has greatly contributed to the development of equalization and standardization of public library services. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 11 figure 6. changsha library no-touch interaction self-service hall. figure 7. taiyuan library no-touch interaction self-service hall. 24-hour self-service library the 24-hour self-service library, a contactless phenomenon in china’s public libraries, was introduced in 2006 and officially launched in 2007 by dongguan library and followed by shenzhen library’s initial batch of ten self-service libraries. the success of the shenzhen model has sparked a boom in the construction of self-service libraries in china, with 77% of the chinese public libraries surveyed having opened self-help libraries. the development of self-service libraries is divided into two types of service models: space-based self-service libraries (see fig. 8), i.e., unattended libraries with a certain amount of space for use, in which patrons can freely select books and read for leisure, such as 24-hour city bookstores; and a cabinet-type self-service library (see fig. 9), similar to a bank atm with an operating panel and similar in appearance to a bookcase, which allows real-time data interaction with the central library via the network. the eight self-service libraries in taiyuan library in shanxi can provide self-service book borrowing services through the new model of library + internet + credit, which allows patrons to apply for a reader’s card without a deposit and make reservations online and deliver books to the counter (see fig. 10). by cross-referencing the reader’s card with the patron’s face information, the guangzhou self-service library provides self-service borrowing and returning services for patrons through face recognition. there are many similar self-service libraries in china, which provide various types of patron services in different forms, largely reducing direct contact between patrons and librarians, and between patrons and readers. for example, when the pandemic was most severe, data collected from the ningbo self-service library showed that 7,022 physical books were borrowed and returned from january to march 2020, 50% more than in a normal year.25 information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 12 figure 8. space-based self-service libraries. figure 9. cabinet type self-service library. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 13 figure 10. taiyuan self-service library. the popularity of 24-hour self-service libraries in china is first and foremost due to the strong support and financial investment of government departments in the construction of self -service libraries. secondly, the features of self-service libraries, which are convenient, time-independent, time-saving, efficient, and diversified, are in line with modern lifestyles, integrating public library services into people’s lives, increasing the visibility and penetration of public library patron services, and maximizing patrons’ needs in reading. network services there is a wide range of network services but the most common are seat reservation, online renewal, and overdue fee payment (see fig. 11). the survey found that 89% of chinese public libraries offer at least one of these network services, indicating a high adoption rate of network services. in 2002, online renewals began to appear in china and then gradually became popular. most of the public libraries in china provide this service in the personal library or wechat official account. the rate of adoption of network service is as high as 85% in the 128 public libraries surveyed. the prevalence of seat reservation services is not high. only 28% of the public libraries surveyed offered seat reservation services. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 14 figure 11. percentage of large chinese public libraries that provide network services. coverage of the online overdue fee payment service was even lower with only 21% of public libraries providing access. however, some libraries have replaced the overdue fee system with other methods, such as the shantou library’s lending points system. in the system, the initial number of points on a patron’s account is 100, with two points added for each book borrowed and one point deducted for each day a book is overdue. when the number of points deducted on the account reaches zero, the reader’s card will be frozen for seven days and cannot be used to borrow books. after the freeze is lifted, the number of points will be reset to 20.26 in summary, contactless services in china’s public libraries are moving in a more humane direction. online reference services as a type of contactless service, online reference services are extremely helpful in developing access to documentary information resources. the survey shows that 94% of public libraries provide online reference services. online reference services are available by telephone, website, email, qq, and wechat. telephone reference and website reference are the earliest forms of contactless service, with the highest usage rates of 79% and 71% respectively among public libraries surveyed. this is followed by slightly lower coverage of email reference and qq reference at 55% and 48% respectively. wechat

reference service tools. other online reference methods such as microblog reference and intelligent robot reference are present in chinese large public libraries. real-time reference is labor-intensive and timeconsuming, and where librarians may be unavailable to provide an immediate response, intelligent robotic referencing can make up for the problem of consultants being online full time. applying intelligent robots to library reference can also provide accurate and personalized consultation services according to patrons’ needs and behavioral patterns, greatly improving the quality, effectiveness, and satisfaction of consultation services. for example, the zhejiang library has an online reference service which includes online 24-hour robot reference and offline message modules. patrons can also choose expert reference and see available reference experts in the expert list and their details, including name, library, title, specialties, status, etc.27 in addition, the hunan library provides joint online reference, which is a public welfare platform of the hunan provincial literature and information resources common construction and sharing collaborative network, to provide online reference services to the public. eleven member units, including hunan library, hunan university library, and hunan science and technology information institute benefit from the rich literature resources, information technology, and human resources of the network, and all sites work together to provide free online reference advice and remote delivery of literature to a wide range of patrons, as well as advisory and tutorial services to guide patrons on how to use the library’s physical and digital resources.28 smart services without personal interactions driven by artificial intelligence, blockchain, cloud computing, and other technologies, libraries are evolving from physical and digital libraries to smart libraries. smart services without personal interactions are a fundamental capability of smart libraries. this survey found that the coverage of 4% 79% 71% 55% 48% 16% 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% others telephone website email qq wechat information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 16 smart services was 52%, with virtual reality coverage at 21%, face recognition coverage at 20%, and swipe face to borrow books at 9%. face recognition can be used in library resources services, face gates, security monitoring, self-checkout, and other online and offline real-name identity verification instances, which can improve the efficiency of identity verification. the biggest advantage of face recognition is that it is contactless and easy to use, avoiding the health and safety risks associated with contact identification such as fingerprints. swipe face to borrow books is one of the applications included in face recognition technology that allows patrons to quickly borrow and return books by swiping faces, even if they have forgotten their reader’s card. this technology also tracks the interests of patrons based on their borrowing habits and history records, providing them with corresponding reading recommendation services. it is worth noting that chinese public libraries have a rich variety of smart service methods. in terms of vr technology applications, the national library of china launched the national library virtual reality system in 2008, the first service in china to bring vr technology to the public eye. the virtual reality system provides patrons with the option to explore virtual scenes and interact with virtual resources available in the library. the virtual scenes are distributed by using computer systems to build realistic architectural structures and reading rooms, so that patrons can learn about the library in the library lobby with the help of vr equipment. virtual resources are digital resources presented in virtual form. the technology combines flash and human gesture recognition systems, allowing patrons to flip through books touch-free at virtual reality reading stations, enhancing the reading style and interactive experience. in addition, the fuzhou library is concerned with the characteristics of different groups of people and has made virtual experiences a focus of its services, using vr technology to innovate reading methods, such as presenting animal images in 3d form on a computer screen, which has been welcomed by a large number of readers, especially children. shanghai library, tianjin library, shenzhen library, chongqing library, and jinan library have introduced vr technology into their patron services as to attract more users. in terms of blockchain applications, the national digital library of china makes use of the special features of blockchain technology in terms of distributed storage, traceable transmission, and high-grade encryption to provide full-time, full-domain, and full-scene copyright protection for massive digital resources and promotes the construction of intelligent library services. related to big data technology, the shanghai library provides personalized recommendation services for e-books based on the characteristics of the books borrowed by readers. patrons using a mobile phone can scan a code on borrowed books and click on the recommended book’s cover for immediate reading.29 conclusion & recommendations an in-depth analysis of the contactless service strategy will help to steadily improve the smart library development process in public libraries and to support their transition to smart libraries. this report provides a systematic framework for contactless services for public libraries based on a survey and assessment of the contactless service status of large public libraries in china. contactless patron services, contactless space services, contactless self -services, and contactless extension services are the four key components of the framework (see fig. 13). information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 17 figure 13. a systematic framework of contactless services for public libraries. providing contactless patron services patron services are the heart and soul of each public library. the library’s services providing no personal physical contact or touch-free connection with patrons are referred to as contactless patron services. this includes book lending, online reference, digital resources and network reading promotion. at present, most chinese public libraries have few contactless lending options, making it difficult to meet the needs of patrons who cannot access the library due to covid-19 or transportation difficulties for various reasons. therefore, public libraries can enrich their existing book lending methods by providing patrons with contactless services, such as book delivery and online lending, to create a convenient reading environment. a focus on digital resources is fundamental to achieving contactless patron services. at present, some public libraries in china neglect the management of digital resources due to the emphasis on paper resources, and digital resources are not updated and maintained in a timely manner, which leads to the inability of patrons to use them smoothly; therefore, the effective management of digital resources in libraries is crucial. in addition, public libraries can carry out activities such as network reading promotion and reader education to effectively improve the utilization of library resources. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 18 building contactless space services contactless space services refer to the touch-free interaction between physical space and virtual space. physical space services mainly include self-reservation of study rooms, discussion rooms, meeting rooms, as well as providing venues for public lectures or exhibitions, etc., to fulfill the space demands arising from patrons’ access to information. virtual space services mainly include building spaces for collaboration and communication, creative spaces, information sharing spaces, and cultural spaces, providing a virtual integrated environment for patrons’ needs for information exchange and acquisition in the online environment. public libraries can develop their activities through different channels according to the characteristics and elements of physical and virtual spaces, so that libraries can evolve from “library as a place” to “library as a platform.” the combination of an offline library space and an online library platform provides a more convenient and accessible library experience for patrons. implementing no-touch interaction self-services no-touch interactive self-service plays a pivotal role as one of the service forms of the contactless service strategy. it mainly includes no-touch interaction self-services such as information retrieval, resources navigation, self-checkout, and self-printing. public libraries can set up no-touch interaction self-service sections on their official websites or social media accounts to help patrons quickly access up-to-date information from anywhere and at any time. developing contactless extension services in the three dimensions of time, space, and approach, contactless extension services refer to the mutual extension of the library. public libraries can be open year round on a 24/7 basis or during holidays without librarians, allowing patrons to swipe their own cards to gain access. the traditional collection of paper books should not only be available in offline libraries but can extend to individual self-service libraries or city bookshops. libraries can approach patrons with a more individualized service strategy. for example, some public libraries provide a service called build a book bag, where librarians select books according to the patron’s personal interests and reading preferences and deliver them to a designated location. limitations and prospects after analyzing the current status of contactless services in large public libraries in china, this paper finds that contactless services such as reference and access to digital resources are well established in chinese public libraries. on the other hand, the availability of contactless applications such as no-touch interaction self-services, network services, and smart services without personal interaction are less well-developed. despite the rapid development of touch-free services and their variety, public libraries in china have not yet implemented a system of contactless services. this paper proposes a systematic framework to improve the development and practice of contactless services in public libraries and interrupt the spread of covid-19. the framework includes four core modules: contactless patron services, contactless space services, contactless self-help services, and contactless extension services. it is foreseeable that contactless services will become the mainstream of public library services in the future. information technology and libraries june 2022 contactless services | guo, yang, yuan, ma, and liu 19 endnotes 1 fred griffith, “identification of the meningococcus in

contactless extension services limitations and prospects endnotes lib-mocs-kmc364-20131012112749 147 who rules the rules? "why can't the english teach their children how to speak?" wondered henry higgins, implying that a lack of widely and consistently followed rules of usage created linguistic backwardness and anarchy. higgins' question might be rephrased today as: "when will the code teach its founders how to catalog?" the library of congress has historically fitted catalog codes to its own practices rather than following them slavishly. the best example is the lamentable policy of superimposition: continued use of preestablished forms of names that are not in compliance with the paris principles or aacrl. this was a cause of widespread confusion and complaint and the practice was eventually discontinued ... well, sort of discontinued. the various interpretations of aacrl, the inclusion of new rules, and pressure for further modifications eventually led to the drafting of aacr2, a code that was supposed to end variance and controversial practices. one might assume that including lc as a principal author of the new text and an lc official as one of the editors might result in a code that it could actually follow. judging by the spate of exceptions and interpretations made so far (more than 300), this has not been the case. in the place of superimposition, we have new impositions known as "compatible headings." they may not be readily ascertained according to the rules, but have been granted a sort of bibliographic squatter's rights. although it would be simpler for catalogers to follow the rules consistently, they must instead check several cataloging service bulletins and name authorities to see whether lc has determined that a given personal, corporate, or serial name is already "compatible" with aacr2. this can result in cataloging delays, higher processing costs, and inconsistent entries. aacr2 and uncertainties regarding its application by lc have been widely credited with lower cataloging productivity. this is not to imply that lc is behaving in a strictly arbitrary or capricious manner vis-a-vis the code. they can be seen as caught on the horns of a trilemma, with vast internal needs and increasing external demands competing for a shrinking budget. president reagan may have whispered sweet nothings during national library week, but during budget hearings it became clear that libraries are not as "truly needy" as impoverished generals and interior decorators. decisions to depart from aacr2 have been based primarily on cost factors. the decision by the rtsd catalog code revision committee and the joint steering committee not to consider cost and implementation factors has led both to widespread opposition to the code resulting in a one-year delay in implementation, and to the modifications that lc has made and is making. some variations such as using "dept." for "depart148 journal of library automation vol. 14/3 september 1981 ment" and "house" for "house of representatives" make fiscal and common sense. many other lc changes are simply bibliographic nit-picking, minor irritants to catalogers who must flip back and forth between the text of aacr2 and half a dozen bulletins to settle a minor point of description. why didn't lc representatives attempt to say, "wait a minute-we just can't do that now," while the code was being considered rather than after it was published? anyway, considering that lc was starting up a whole new catalog and closing the old one, one wonders why rules not to be applied retrospectively had to be tinkered with to such an extent. major questions still to be resolved include not only the compatiblename quandary, but the treatment of serials, microform reproductions, establishment of corporate names and determination of when works "emanate from" corporate bodies, and the romanization of slavic names. the decision to use title entry for serials and monographic series even in the case of generic titles has been controversial. there are, of course, exceptions to the rules, and there will be differences in how uncertain catalogers construct complex entries with parenthetical modifiers. unfortunately, rules establishing entries for serials have sometimes been muddied rather than clarified in the bulletin. consider the example in the winter 1981 issue wherein the bulletin of the engineering station of west virginia university is entered under "bulletin," while the same publication for the entire university is entered under "west virginia university bulletin." also, consider the complex cross-reference structure required to direct users between the two files, both of which may well be split again,' historically, between author/ title and title main entry. this is a special problem in the case of large monographic series generated by corporate bodies. the lc position on microform reproductions of previously published works is clearer, but is still a point of controversy. they have decided to provide the imprint and collation (er, make that "publication, distribution, etc., area" and "physical description area") of the original work, with a description of the microform in a note. in other words, they're sticking to aacrl. the rtsd ccs committee on cataloging: description and access is currently trying to resolve this conflict, one in which many research libraries have sided with lc. this body is also trying to unravel the mystique of "corporate emanation'' introduced in aacr2. another sore point has been the lc decision to follow an alternative rule, which prefers commonly known forms of romanized names over those established via systematic romanization. that lc is correctly following the spirit of the general principle for personal names is little comfort to research libraries with large slavic collections. how are other libraries responding to the murky form of aacr2? some are closing old card catalogs and continuing them with com or temporary card supplements. some of these are establishing cross-reference links between variant forms of names between catalogs, while others are not. editorial/dwyer 149 some are keeping their catalogs open and shifting files, while others are splitting files. some are shifting some files and splitting others. aa cr2 was intended to provide headings that could be easily ascertained by the user. ironically, the temporary result is scrambled catalogs: access systems involving multiple lookups and built-in confusion . until most bibliographic records are in machine-readable form under reliable authority control this will continue to be the case. authority control, it would seem, has long been an idea whose time has come but whose application is yet to be realized. the cooperative efforts of the library of congr~s and the major bibliographic utilities to establish reliable automated authority control will do much to ameliorate the problems presented by aacr2. it would also be helpful if lc, perhaps with the financial assistance of other libraries, networks, and foundations, would publish what might be called aacr2¥2-not a new edition of the code but one accurately reflecting actual lc practice. finally, future code makers would be wise to consider cost and other implementation factors in their deliberations. professor higgins, ever the optimist, would rather sing "wouldn't it be !overly" than hear another verse of "i did it my way." james r. dwyer editor's notes title change it often seems that the only things that change their names as often as library publications are standards organizations. not to be left out, jola will be called information technology and libraries beginning with volume 1, number 1, the march 1982 issue . this name was approved by the lit a board in san francisco this june as more accurately reflecting the true scope of the journal. new section with this issue, we are initiating a new section: "reports and working papers." this is intended to help disseminate documents of particular interest to the]ola readership. we solicit suggestions of documents, often developed as working papers for a specific purpose or group but of interest and value to our readership. in general, documents in this section are neither refereed nor edited. mitch i take great personal pleasure in publishing mike malinconico's speech upon presenting the 1981 lita award to mitch freedman. readers' comments we do continue to solicit suggestions about the journal but receive few. is anybody reading it? if you have any thoughts about what we should or shouldn't do, we would welcome your sharing them. letter from the editors

challenge for libraries since the development of online databases. library systems have attempted to meet this challenge, but link resolvers and early direct linking tools often fell short of patron expectations. in the last several years, a new generation of direct linking tools has appeared, two of which will be discussed in this article: third iron’s libkey discovery and quicklinks by ex libris, a clarivate company. figure 1 shows the “download pdf” link added by libkey. figure 2 shows the “get pdf” link provided by quicklinks. the way we configured our discovery interface, a resource cannot receive both the libkey and quicklinks pdf links. these two direct linking tools were chosen because they were both relatively new to the market in april 2021 when this analysis took place and they can both be integrated into primo ve, the library discovery system of choice at the authors’ home institutions of suny college of optometry and ferris state university. through analysis of the frequency of direct links, link success rate, and number of clicks, this study may help determine which product is most likely to meet your patrons’ needs. figure 1. example of a libkey discovery link

rubel literature review over the past 20 years link resolvers and direct linking have evolved in tandem. early link generator tools, such as proquest’s sitebuilder, often involved a process that “… proved too cumbersome for most end-users.”1 five years later, tools from ebsco, gale, ovid, and proquest had improved, but they were all proprietary. bickford postulates that metadata-based standards, like openurl, may make linking as simple as copying and pasting from the address bar; however, they may be more likely to fail “… as long as vendors use incompatible, inaccurate, or incomplete metadata.”2 the first research was wakimoto’s 2006 study of sfx, which relied on 224 test queries and 188,944 individual uses for its data set. 3 of those queries, 39.7% of search results included a full-text link and that link was accessed 65.2% of the time. unfortunately, wakimoto also discovered that 22.2% of all full-text results failed and concluded that most complaints against sfx were problems with the systems it links to and not the link resolver itself. alth ough intended to be provider-neutral, the openurl standard is, in fact, vulnerable to metadata omissions. content providers, whether aggregators or publishers, have a vested interest in link stability and platform use and have therefore invested in building direct link generation tools. in 2006, grogg examined ebsco’s smartlink, which checks access rights before generating the link; proquest’s crosslinks, which was used to link from proquest to another vendor’s content; silverplatter and links@ovid, which relied on a knowledge base in the terabytes for static links.4 in 2008, cecchino described the national library of medicine’s linkout tool for selected publishers within pubmed.5 they also described two ovid products: links@ovid and linksolver, noting that the former is similar to linkout and the latter is similar to sfx. most of the time these tools worked well, but their use was restricted to a particular platform or set of publishers. as online public catalogs became discovery layers, direct linking became a feature of the library management system. two studies have been done thus far: silton’s analysis of summon and stuart’s analysis of 360 link. in 2014, silton tested the percentage of full-text articles retrievable from summon by running a test query and examining the first 100 results. over a year, the total success rate for unfiltered queries rose from 61% to 76%. after direct linking was introduced, the success rate of link resolver links rose to 65.8–73% and direct links succeeded 90.48–100% of the time. silton concluded, “while direct linking had some issues in its early months, it generally performs better than the link resolver.”6 in 2011, stuart, varnum, and ahronheim began testing the 1-click feature of 360 link on 579 citations, 82.2% of which were successful. after direct linking became an option for summon in 2012, 61–70% of their sample relied on it. “between direct linking and 1-click about 93 to 94% of the time an attempt was made to lead users directly to the full text of the article … [and] … we were able to reach full text … from 79% to about 84% of the time.”7 direct linking outperformed 1-click with a 90% success rate compared to 58–67% for 1-click. stuart also compared the actual error rate with one based on user reports and discovered that “relying solely on user reports of errors to judge the reliability of full-text links dramatically underreports true problems by a factor of 100.”8 openurl links were especially alarming with approximately 20% of them failing. although direct linking is more reliable, stuart closes by noting that direct linking binds libraries closer to vendors thereby decreasing institutional their flexibility. information technology and libraries june 2023 a tale of two tools 3 locascio and rubel methods the goal of this project was to assess two of the latest direct linking tools: ex libris’s native quicklinks feature and third iron’s libkey discovery. we performed a side-by-side comparison of the two tools by searching for specific articles in primo ve, the library discovery system used by the authors’ respective home institutions, suny college of optometry and ferris state university, and measuring • how often each vendor’s direct links appeared on the brief record; • success rate of the links; and • number of clicks it takes from each link to reach the pdf full text. both suny college of optometry and ferris state university use ex libris’ alma as their library services platform. alma provides a number of usage reports in their analytics module. we sourced the queries used in our analysis from the alma analytics link resolver usage report. the report contains a field number of requests, which records the number of times an openurl request was sent to the link resolver. an openurl request is sent to the link resolver when the user clicks on a link to the link resolver from an outside source (such as google scholar), for example, when the user submits a request using primo’s citation linker or when the user accesses the article’s full record in primo by clicking on either the brief record’s title or availability statement. this means that results that have a direct link (whether a quicklink or libkey discovery link) on the brief record will not appear in the report if the user clicked the direct link to the article. thus, in order to create test searches that would be an accurate representation of articles being accessed, we used article titles taken from suny optometry’s october 2019 alma link resolver usage report— a report that was generated prior to the implementation of both libkey discovery and quicklinks. the report was filtered to include only articles with the source type of primo/primo central to ensure that the initial search was taking place within the native primo interface, as requests from outside sources like google scholar or from primo’s citation linker are irrelevant to this analysis. this filtering generated a total of 412 articles. after further removal of duplicates and non -article material, there were 386 article titles in our test query set. we created two separate primo views as test environments: one with libkey discovery and the other with quicklinks. we ran the test searches twice in each view. in the first round of testing, we recorded whether a direct link was present. we also recorded the name of the full-text provider (if present), as well as whether the article was open access. suny optometry does not filter their primo results by availability; therefore, many of the articles included in the initial search did not have any associated full-text activations. since these articles are irrelevant to our assessment, we removed them before analyzing the first round of data and proceeding with the second search. the exception to these removals were articles identified as open access by unpaywall, as the presence of unpaywall links is independent of any activations in alma. furthermore, third iron’s libkey discovery and ex libris’ quicklinks both incorporate unpaywall’s api into their products to provide direct links to pdfs of open access articles. this functionality helps fill coverage gaps where institutions may not have activated a hybrid open access journal due to its paywalls. therefore, we are including the presence of direct links resulting from the unpaywall api when determining whether a libkey discovery link or quicklink is present. after filtering for availability, we had 254 article titles for the first round of searching and analysis. the initial analysis revealed the need to further filter the information technology and libraries june 2023 a tale of two tools 4 locascio and rubel articles used for the second round of searching, which would provide a much closer comparison of the two direct linking tools as third iron had partnered with more content providers than ex libris. controlling for shared providers would give a more accurate representation of how each direct linking tool performs in relation to the other. when controlling for shared providers and open access articles, we were left with 145 article titles for the second query set. during the second round of searching, we measured whether the direct link was successful in linking to the full text—meaning that the link was neither broken nor linked to an incorrect article—and how many clicks were necessary to get from the direct link to the article pdf. along the way, additional qualitative measures were observed, such as document download time and metadata record quality. while not as easy to measure as the quantitative data, these observations provided additional insight into the strengths and weaknesses of each of these direct linking tools. since april 2022, when our research was conducted, ex libris has added several quicklinks providers, possibly increasing the current number of quicklinks available. additionally, both rounds of searching were conducted on campus, so our analysis excludes any consideration of authentication and/or proxy information. results of the 254 articles searched, 208 (82%) had libkey discovery links present while 129 (52%) had quicklinks present. while this seems like a large discrepancy between the two direct link providers, it can be explained by the fact that during the time of testing, ex libris was collaborating with fewer content providers than third iron. ex libris has since added more providers. while the provider discrepancy meant that there were many instances where a libkey discovery link was present where a quicklink was not, there were 5 articles where a quicklink was present while a libkey discovery link was not. as mentioned previously, the criterion for the 254 articles included in the second round of searching was that the articles must be activated in alma or must be open access. of these 254 articles, we identified 137 (54%) as open access. of those open access articles, 132 (96%) had libkey discovery links present, and 118 (86%) had quicklinks present. we found that 113 (82%) of the open access articles had both libkey discovery links and quicklinks present. we also discovered within this set of 137 open access articles that 30 (22%) were from non-activated resources. of those 30 open access articles from non-activated titles, all 30 (100%) had libkey discovery links appearing on the brief results and 24 (80%) had quicklinks. to get a better idea of how libkey discovery links and quicklinks compared in terms of linking success, we filtered to only those articles available from providers who were participating in both libkey discovery links as well as quicklinks. since both direct linking tools use unpaywall integrations, we continued to include open access articles. this filtering resulted in 145 articles where libkey discovery links were present in 137 articles (94%) while quicklinks were present in 129 articles (89%). we found that 123 (85%) of these 145 articles had both libkey discovery links and quicklinks present. there were 2 (1%) articles that had neither libkey discovery links nor quicklinks present despite being activated in a journal currently participating as a provider in both direct linking tools. there were also 14 articles (10%) that had libkey discovery links but information technology and libraries june 2023 a tale of two tools 5 locascio and rubel not quicklinks; all of these articles were open access. in total, of the 145 articles searched, 128 (88%) were identified as open access. as for the 137 libkey discovery links, 130 (95%) of them successfully linked to the article. on average it took 1.07 clicks to get to the pdf of the article. of the 129 quicklinks, 126 (98%) of them successfully linked to the article. on average it took 1.07 clicks to get to the pdf of the article. we also attempted to measure the time it took for the pages to load after the initial click on the libkey discovery links and quicklinks; however, the tools used to measure this, as well as the environments in which the links were being clicked, proved too varied to provide an appropriate comparison. nevertheless, we noted observations such as the page load times after clicking on libkey discovery links and quicklinks were generally consistent, but quicklinks attempts to connect to the wiley platform took a significant time (at least 10 seconds) to load. conclusions with high article linking success rates, both third iron’s libkey discovery and ex libris’ quicklinks deliver on the promise to provide fast and seamless access to full-text articles. however, the libkey discovery tool far outpaces quicklinks when it comes to coverage. both direct linking tools perform well with open access articles, supplying libraries with better options for full-text links to articles that may be in hybrid journals. as with any kind of full-text linking, both direct linking tools rely on metadata. in conclusion, while libkey discovery provides a more complete direct linking solution, both libkey discovery and quicklinks are reliable tools that improve primo’s discovery and delivery experience. endnotes 1 david bickford, “using direct linking capabilities in

computer system is becoming the most systematically replicated main-frame facility, with a broad range of future possibilities, including that of a truly turnkey system. wln's experience indicates that, if a system is designed for ease of maintenance at perhaps some sacrifice of efficiency, it will be readily transportable and allow others to obtain the benefits of a highly sophisticated bibliographic capability without the everincreasing cost of original development and, more importantly, without having to support the ongoing maintenance of a unique system. a general planning methodology for automation richard w. meyer, beth ann reuland, francisco m. diaz, and frances colburn: clemson university, clemson, south carolina. introduction a workable planning methodology is the logical starting place for the successful implementation of automation in libraries. an automation plan may develop on the basis of an informal arrangement or from the efforts of one individual, but just as often, automation plans are developed by committees. an automation planning committee must determine and execute some kind of planning methodology and is more likely to be successful if it starts with clear guidelines, good leadership, and a thoroughly proven approach. as a summary review of the literature will bear out, many libraries have developed their own planning techniques inhouse. some of these, which are addressed to the issues of cataloging rule changes and public-access catalogs, have been very well thought out .1 however, these techniques are generally not directed to planning for communications 205 library-wide automation, and are usually designed to meet the specific needs of an individual library. although the pattern for these studies is often similar, they do not seem to be based upon any general automation design methodology. neither, in addition, does there seem to be a general methodology available through any external library agency. the office of library management studies of the association of research libraries has developed a number of programs designed to assist libraries with their planning efforts, some of which appear to be useful in automation development. 2 but for many libraries, these programs may be too broad, too time-consuming or too expensive. as an alternative, some libraries will need to look elsewhere for a general automation planning methodology. this problem was addressed by the administration of the clemson library, and was resolved in a unique way. background the robert muldrow cooper library of clemson university has the responsibility of acquiring, preserving, and making available for use the many materials needed by faculty and students in their research and instructional efforts. at a typical landgrant institution like clemson, the amount of scholarly publishing and the pressure to develop research proposals has risen sharply in recent years . the increased needs of users working with an expanding and diversified collection have resulted in a doubling of circulation activity, and have required the growth of library staff by 70 percent over the last decade . furthermore, acquisition, processing, and access problems are compounded by the high inflation rate of materials, particularly serial publications, and manpower costs. even though user demands heavily burdened the traditional manual systems, the extent of library automation at clemson had been limited to a batch circulation system, a simple serials-listing capability, and the use of bibliographic utilities. although it had been generally accepted for some time that the acquisitions and fund-control functions at clemson were in need of automation, no concrete approach to develop206 journal of library automation vol. 14/3 september 1981 ing a system had been established. in addition, there was some concern that the development of an automated acquisitions system shouldn't be initiated without a clear understanding of how such an effort would affect the rest of the functions in the library. with this in mind, and as an initial part of planning, the library administration decided to implement a programmed study to determine specific needs and problems of the whole library at clemson and to determine the attendant costs and benefits of their resolution. since developing the methodology for this kind of study effort inhouse has been shown by experience elsewhere to be both expensive and time-consuming, a planning methodology was sought which could be brought in from outside the library and applied in a timely fashion. the international business machines corporation (ibm), through their local marketing representative, volunteered to supply that methodology by means of an education industry application transfer team (att} study. in order to implement the study, a team was organized consisting of representatives from the library, from the university's division of administrative programming services (daps), and from the ibm corporation. the purpose, approach, and results of that study constitute the rest of this paper. purpose the application transfer team methodology was implemented to fulfill a fourfold purpose. • first, it was necessary to act on the recognized need for a library-wide automation plan with something tangible that library and university administrators could use in the decision-making process. • second, basic objectives and implementation estimates were required to provide groundwork to the development of systems specifications and evaluation. • third, the planning process needed to provide a forum for meaningful participation by a number of library staff and users. • fourth, the planning needed to be accomplished rather quickly. the att met all these requirements. although the att study technique is generalized for work on any problem in the education arena, it seems particularly well suited to the library environment because it is oriented toward developing applications that solve production problems. the application transfer team methodology was developed by the ibm corporation for customer use. the a tt methodology evolved from ibm's business system planning function, which has been operational since the early 1970s. although the methodology has been used several times in the academic environment, this is the first time, to our knowledge, that it has been used in a library operation. the strength of the att is that it helps members of a team with diverse backgrounds to understand the environment under study. its final goal was "to improve operational productivity, provide better service to students, and provide information which can enhance management planning and decision making."3 put to work, the methodology is straightforward and effective. from beginning to end, the a tt process took clemson slightly more than three months elapsed time. total work time (including all report writing) for library staff was approximately one thousand man hours. as the initial step with the a tt methodology, it was necessary to engage a sponsor and to select a team . for this study, the sponsor chosen was the dean of graduate studies, who reported directly to the vicepresident for academic affairs. in turn, the director of mmpnting and the director of the division of administrative programming services (daps) reported to the dean of graduate studies. although it was not critical that the sponsor be intimately involved in the project, his level of authority within the university administration would help to secure acceptance of the study's recommendation. the sponsor also provided cogent advice along the way, based upon his understanding of institutional resources, and he served as a communication link with other university administrative offices. the study team was chosen by the library administration with the intention of getting diverse involvement and expertise. library staff included the associate director, the head of circulation, the serials cataloger, and a reference librarian. although only the associate director brought significant experience in library automation development, the head of circulation contributed substantial practical experience with automation systems. the cataloger offered specifics of bibliographic problems, cataloging rule changes, and serials control issues, and the reference librarian contributed a comprehensive knowledge of informationretrieval concerns. outside staff included the director of daps, who furnished details on the clemson computing environment, and an ibm marketing representative, who provided appropriate help with hardware capabilities, the att metnodology, and legwork. in addition, clemson was also able to engage the help of a representative of ibm's education industry division to guide the a tt efforts on the basis of his experience in the use of the methodology. from time to time, other ibm and daps staff were involved in assisting with interviews and report writing. the associate director served as team chair in order to act as spokesperson, to coordinate team effort, and to edit the final report. methodology the application transfer team methodology is applied in six phases. ibm recommends that these phases be conducted sequentially, and that they last from five to sixteen weeks, depending on the size of the problem. throughout the process, verbal reviews were conducted by the team with the sponsor and with the library staff. the first phase involved an organizational session. following the introduction of team members, the ibm education industry division representative presented an overview of the methodology and explained the mechanics of the a tt study process. the team then established the scope of the study by choosing an application area on which to focus and by determining the general objectives of the final system to be implemented. since part of the purpose of the project was to develop a plan for librarywide automation, it was quickly recognized by the team that the application area should be an integrated library information system. however, the ibm representative suggested that this scope was too broad for the study and that one functional area such as communications 207 acquisitions be chosen, with other functions reserved for subsequent att studies. given time constraints, a compromise arrangement was made in which serials control was determined as the scope. since serials control is a single functional area, but encompasses nearly all bibliographic issues, it served as a microcosm of overall library operations. therefore, it was generally accepted that a plan that effectively accommodated serials would constitute an integrated system plan. the organizational phase continued by determining who to interview during the data-collections phase and by setting up an interview schedule. this phase was concluded by developing an outline of the final report and by assigning writing responsibilities to individual team members. the data-gathering effort constituted phase two. this involved structured interviews of representative staff of each unit of the library who were involved in routine interactions with any phase of serials control at clemson. interviews were conducted with staff from acquisitions, cataloging, circulation, reference units, and branch libraries as well as the university business office, students, and faculty. following an outline in the att, each person interviewed was asked for specific details of his work with serial publications regarding (1) interfaces (or points of interaction), (2) concerns or needs, (3) suggested improvements, (4) expected values or benefits of improvements, (5) work volume, and (6) cycles. data gathered in each of these interview sessions were immediately documented in a letter to the interviewees. these letters were reviewed by those interviewed for corrections and adde::tl delail. data from completed and documented interviews were consolidated during the third phase of the study into a matrix of each of the six questions plotted against operational areas of the library, graphically designating areas of the greatest concern to the largest part of the library. this composite was analyzed to separate problems that could be reasonably handled by an integrated automation system from those that needed the attention of administrative policy and direction. functions for automation consideration were then examined in a 208 journal of library automation vol. 14/3 september 1981 "blue sky" session of the committee to envision what system would accommodate the specifications for serials control and access that each library unit and serials user required. from this session a synthesis emerged of the architecture for an integrated system. 4 this architecture included a description of the basic relationships of functional modules of the system, a list of the various files needed to contain system information, and a list of data elements required for bibliographic holdings, acquisition, and patron records in the system database. phase four called for the translation of the architecture and general system requirements into modules on basic access, acquisition or processing functions, and into the individual programs needed to execute each module. the team divided into two parts. the ibm and daps personnel, with the associate director, listed the modules and programs and formulated descriptions of each. part of the description effort involved drafting approximate flowcharts of each program. using algorithms developed by ibm, these descriptions were used to assign estimates of person hours required to create the necessary modules. in order to determine the overall cost of system development the person-hour figures were converted to dollars using an average hourly cost for clemson daps personnel. committee members not involved in program/module design formed a group to evaluate anticipated benefits defined in the interviews, to collect data from library staff to support these expectations, and to assign a value to them. benefits from reduced file maintenance, processing, and tracking time were valued as person hours saved by the new system . additional improvements were projected for the system's capability for better fund control, more complete and immediate on-order, claiming, and inprocess information, and statistical collection development/use data. these benefits were assigned the value of estimated duplicate and inappropriate material acquired under the present system. a value was not assigned to user benefits. faculty and student satisfaction is intangible, and variable from case to case. enhanced user service was recognized as a substantial benefit of the proposed system, but was not quantified. the cost factors determined in phase four were consolidated with derived benefit values to form a cost/benefit analysis, which constituted phase five. in the sixth and final phase an implementation plan was formulated. this plan, along with recommended target dates, was presented orally to library staff and university administration. in addition, the entire process, recommendations, and plan of action were documented in a written report. 5 results within the a tt report were a description of the current library environment, objectives and description of the proposed system, implementation considerations, a cost/benefits analysis, and recommendations for a plan of action. although care was taken to "walk through" the function of each module of the described system, the report was not intended to provide detailed computer program specifications ready to be coded by a programmer. it described a useful and powerful integrated serials system in sufficient detail to be a working tool in the hands of a knowledgeable systems analyst to match (or revise) already available systems and programs to the library's specifications. the report itself also served as an effective communication link with the university administration, setting out library concerns and giving rational solutions to the pervasive problem of serials control and, in the long term, to an integrated library information system. the timing of the a tt study was fortunate for the clemson library. the university was on the eve of an accreditation selfstudy. as often happens with the examination of any organization, a host of related, but unacknowledged , problems surfaced in the course of the att study. during the interviews, staff members felt free to bring up matters of unclear policies, misunderstood hierarchical arrangements, and staffing inadequacies throughout the library. the number and importance of nonautomation concerns was significant enough that an administrative report was written to articulate these problems to the university administration. 6 it is interesting to note also that, while in every instance the team received enthusiastic cooperation from all those interviewed , there was fear among some staff members that any automation project would necessarily cut staff positions. once this worry was identified, the study team was able to allay those fears by explaining the study's purpose. one of the greatest contributions of the att study has been the direction it has given the library for future goals and priorities. by focusing on the problems of serials control, the team evaluated a microcosm of library problems. investigating these problems in the environment of more limited budgets, possible future closing or freezing of the card catalog, and increased user demands for services has helped the library develop a course of action, a resolve of mission, and a direction for future growth. the staff of daps and the library are conducting a review of existing software and systems potentially appropriate for a comprehensive serials control system. the att study was the tool successfully used to elicit university support for library automation. the university has given its approval, and supplied funding, to proceed with the determination

lib-mocs-kmc364-20131012114231 on their regular clsi equipment in the main library and station branch. on days when housekeeping chores are scheduled, the console operator's job includes turning on the apples so we can begin serving the public when the doors open at 9:00 a.m. unless downtime persists for more than a day, no other routines are done except checkouts. under some circumstances, certain materials might be checked in on the apple, but it is not desirable to do this for newer materials on which holds may have been placed. when the libs 100 is online again, the checkout station is switched back to normal mode and the apple takes over the information desk's port for dumping, rendering that terminal inoperative. dumping continues around the clock until all transactions have been processed from both apples. normal activities proceed at all other terminals. diskettes are dumped in chronological order. as the dumping process operates, a file of transactions eliciting error or exception messages from the libs 100 is created on the apple diskette. this file is available for attention at a later time for manual entry into the database. the chief asset of the dumping process is the accuracy achieved by automatic inputting. when we used paper and pencil, not only was the original writing time consuming, but manual data entry was difficult because of illegible handwriting, inaccurate transcription of the numbers, inaccurate inputting into the database, and lack of available personnel for the job. the cti system resolves all of these difficulties, but a price is paid in the loss of the dumping terminal's services. the public may be less disturbed if a terminal in a nonpublic area is used. but to the department involved, access to the database is a central part of their work and its loss severely limits their output. in fact, dependence on the automated circulation system by all departments in the library has been swift and universal even though we originally assumed the terminals outside the circulation department would be used sparingly. plans are being made to store personnel records in machine-readable form on diskettes. other developments are being put on a back burner until we have less frequent communications 299 need for the apples as backups. however, levels, great neck library's youth department, has several apples of its own on which budding "computerniks" practice their art. for them there are few limits to possible applications-perhaps only the outermost boundaries of imagination. reference 1. joseph covino and

paul: skp associates, new york city. in the 1970s, we entered the period of computer-to-computer communication; we now appear to have reached the second stage of development. today more than seventy publishers are equipped to receive computer tape orders and input them directly to their order fulfillment systems; twenty-six publishers can produce computer invoices and credits for their customers; six are capable of sending monthly updating information about titles, prices, publication dates, and books declared out of print. all of this, however, is based on a system through which computer tapes are sent from buyer to seller and back via the united states mail. the next stepcomputer-to-terminal or computer-tocomputer communication-is just around the corner. historical perspective how did this happen? it started in september 1974 when dewitt c. ("bud") baker, newly appointed president of the baker & taylor company, envisioned the savings his company could find if their customers provided the international standard book number (isbn) on their orders. he also believed that the volume of paper created by the computer was expensive and time-consuming for publishers to handle. 300 journal of library automation vol. 14/4 december 1981 always a visionary, he believed that computers communicating directly with each other would not only save time and money, but would prevent human errors introduced by research clerks or keypunchers. he invited publishers, booksellers, librarians, wholesalers, representatives of school systems, and others to a full-day meeting at thew. r. grace building. this diverse group of individuals discussed the isbn-what it was, what it might do. by the end of the day, the group defined two areas in which efforts might bear fruit. one was educationalpublishers needed to be told the importance of printing valid isbns on their books, in their promotional materials, in their advertising, and on any other source of ordering information, and on the invoices and packing lists they send to their customers. wholesalers, librarians, and booksellers needed to be shown the efficiency their use of isbns on orders introduces to the fulfillment process at publishing houses and wholesaler offices. these functions were assigned to an isbn publicity committee, chaired by franklyn ("lee") rodgers of scribner book company. the second function was the design of computer-tocomputer formats for orders and invoices that would be keyed to the use of isbn as title identifier and would be industry-wide in scope. this function was undertaken by an isbn data transmission committee, chaired by david wolverton, then of brodart. the isbn publicity committee produced a booklet and posters, distributed them at all major conventions, made press releases available, and prepared articles for inclusion in the newsletter of all of the major industry associations. the committee surveyed the use of isbns by publishers and published a list of in-house contacts for isbns. the committee's program was a success! format development the isbn data transmission committee had a more difficult task. the first question they faced was one of basic approach. immediately they decided to proceed with a format for orders rather than invoices. next, they reviewed the level to which the format would be directed. believing it was more appropriate to "crawl before they walked," they decided to develop a format that could be generated on computer tape, which would be mailed from buyer to seller through the united states mail. once there had been experience with that format, work would begin on direct computer-tocomputer communication formats and protocols. the final decision related to form. the majority of people volunteering their time to work on this committee came from the major book publishing houses. additional members included two major bookstore chains, b. dalton and waldenbooks; the new york public library (nypl) and three major wholesalers, brodart, baker & taylor, and the ingram book company. representatives from nypl, r. r. bowker company, and the library wholesaling organizations were familiar with american national standard z39.2bibliographic information interchange on magnetic tape. they felt that this standard, which is the basis for the marc tapes, should also become the basis for an order to be sent on magnetic tape. the majority of the committee, however, was not only unfamiliar with z39.2, but with the concept of programming for variable length records and/or fields. these dataprocessing managers argued that the format basically would consist of sending a quantity and the isbn for each title ordered, not the sending of bibliographic records as such. after review of a strong and well thought out letter from michael malinconico supporting the use of z39.2, the majority held to their decision and the subcommittee, chaired by tom brady, then of baker & taylor, was assigned responsibility for developing the first computer-tocomputer order format. it is a fixed length field and record format. debate continued throughout its development. each publisher hoped to have to do minimal programming in order to interface the new format and the input requirements of his or her specific order fulfillment system. provision was made for minimal bibliographic information if an isbn was unknown. polling of the members resulted in decisions to limit author and title to thirty characters, for instance. shortly before the format was approved by the committee, dick fontaine, then sales manager of b. dalton (now president) and dick lieberman, sales manager of random house decided that they would begin sending tapes in the mail as of january 1975. once the format had been approved, other publishers joined the group. orders were sent from baker & taylor and brodart to random house, john wiley, prentice hall, and doubleday. b. dalton continued to send random house tape orders in a slightly different version of the format. by the end of 1976, it appeared that the task of the isbn publicity committee had become publicizing the order format, rather than the isbn as such. the two committees decided to merge in march 1977, selecting the name book industry systems advisory committee (bisac), as much because it was a pronounceable acronym as for any other reason. development of an invoice format, originally considered of immediate importance by waldenbooks, had been shelved after that company lost interest and the individual chairing the subcommittee working on the format left the field. the next step became reports of experience with the order format. fields left open for individual use came under review for standardized coding; procedures were developed for the marking of information on the outside of the tapes and paperwork to accompany it; some publishers refused to accept tapes without isbns, while others pondered the procedure to separate titles without isbn from those with and then merge the two for discounting purposes. with all of its inadequacies, the format was working. publishers reported saving up to one week of time in processing tape orders. random house analyzed returns for wrong title or wrong edition one year after they began receiving tape orders from dalton, baker & taylor, and brodart. they found an extraordinary 47 percent decrease in that type of misshipment to those three customers. with a few years experience under their belt, bisac decided to revise the format to accommodate the inadequacies and problems members had found with it. in addition, the r. r. bowker company and oclc, inc., had just announced their incommunications 301 tentions of developing acquisition systems which would replace them in the role of "order forwarders." they would prepare orders for other organizations and transmit those orders, on tape or directly online, to the vendor of the organization's choice. this forced bisac to include a field for an "order placer" in addition to the traditional "bill-to" and "ship-to" customer name and address. the revision was approved in february 1977 and called "format 112." (it is this version of the format which has been programmed by publishers and wholesalers noted in the introductory paragraph). bisac members began pressuring b. dalton to convert from their original "preformat 1" format to format 112. in analyzing the cost of doing so, dalton also considered the potential saving they would have if invoices from publishers were received on tape. although they have never made those figures public, the potential was so great that jim nermyr, then their vice president of data processing, agreed to chair a subcommittee to develop an invoice format, paralleling as closely as possible, the order format. once that was approved jim made "selling trips" to new york and elsewhere, convincing over forty publishers to program for the invoice format in return for receiving orders on tape in format 112 from dalton. finally, bisac members began expressing concern about misinformation on orders and invoices. typically, when two organizations agreed to communicate using the standardized formats, they would exchange tapes of titles, descriptions, and the appropriate isbn for each. they would produce error reports and the purchasers would bring their computer records in line with the publisher's. however, once price changes occurred, books were made out of print, or publication dates changed for notyet-published titles, orders carried erroneous information. to resolve this, a subcommittee, chaired by andrew uszak of r. r. bowker company, set about developing what has come to be known as the "title update format." this format allows a publisher to send a monthly tape of all titles on file indicating those fields that have changed since the prior month, or simply sending the isbn and changed field infor302 journal of library automation vol. 14/4 december 1981 mation. six publishers are now sending information in this format to the ingram book company on a monthly basis; others will be doing so shortly. (the format is also the basis for information college textbook publishers send to update the monthly aap microfiche service.) most recent changes at its may 1981 meeting, bisac approved minor modifications to its order and invoice formats. these changes included increasing the zip code field to nine digits and specifying a seven-digit field for the standard address number. the invoice format was modified to accommodate its use for sending credits as well as invoices. these new formats were released in august 1981 and are "titled" order format #3 and invoice format #2. we guess that it will take at least a year before the bulk of those organizations now sending tapes in order format #2 and invoice format# 1 program for the revisions. during 1980, bisac members began expressing concern that the "crawl before you walk" philosophy had stopped in the crawl stage. baker & taylor and brodart, in particular, expressed concern that the generation of tapes was expensive and using the mails introduced such delays that orders were filled more promptly when phoned into publishers than when sent in the bisac format. in addition, oclc, which had programmed the order format into their new acquisition system, agreed that sending this information on tape would be far less effective than transmitting it online to the major vendors. in 1980, bisac established a subcommittee, chaired by jim long of oclc, inc., to develop an alternative version of the order format. this version, with variable length fields and records, is intended for use in a communication mode between the main frames of two computers. we expect there will be deep consideration and long debate on this proposed version at bisac meetings in the next few months, with passage expected in 1982. finally, bisac brought its formats to the attention of american national standards committee z39 (ansc z39) when format #2 was completed. at its may 1981 meeting, the committee decided to ask z39 to officially begin work on formalizing both the order format #3 and the new variablelength order-format alternative as american national standards. the z39 program committee and executive council agreed; ernest muro of baker & taylor is chairing the z39 subcommittee charged with this task. as bisac activities became more widely known, this ad hoc committee strained the resources of its volunteer officers in answering requests for information, for copies of the formats, and in preparing and disseminating the minutes of their meetings to an ever-increasing number of interested individuals and organizations. in 1980, bisac approached the book industry study group, inc. (bisg) with the suggestion that they become a permanent committee of that research organization, whose membership also included publishers, librarians, booksellers, and wholesalers, as well as book manufacturers. the bisg agreed and today supports bisac activities through its offices. at the end of this communication is the address which can be used to request any of the formats from the bisg office. the future automation is here and here to stay. individuallibraries that once considered it impossible to imagine being able to afford a computer now have several-and soon will have more-acquisition systems available to them through independent vendors and through the national bibliographic utilities. wholesalers are gaining computer sophistication, as are publishing houses. as an industry, we are lucky that those volunteer data-processing types who formed bisac and kept it alive were each willing to make the compromises necessary to provide us with a standardized industry-wide format. other industries have not been so lucky, with major vendors using their dollarvolume clout to demand that their customers accept orders in their own , unique formats. however, the need for standardization is known. in 1979 the american national standards institute approved the creation of a new committee-ansc x12-business data interchange. this committee is charged with developing anationa! standard format for transmission of orders, invoices, and other transactions related to the sale of merchandise, and the payment for that sale through electronic funds transfer. bisac and ansc z39 have been carefully reviewing the progress this new committee is making. it appears that the formats that result from their efforts will be variable length fields and sufficiently general in nature to fit the needs of librarians, booksellers, wholesalers, and publishers, along with those involved in the sale and purchase of all other types of commodities. the traditions and laws of this country preclude any organization from "forcing" a library to make use of these standardized formats. however, the cost savings, the guarantee of accuracy of the record received, and the speed with which the order reaches the fulfillment center suggest that these formats will increase in use in the future. we also anticipate that more and more use of the formats will be in an online transmission mode, rather than in the form of computer tapes in the mail. as the volume communications 303 of transmissions grows, we expect that some day messages from purchasers will be forced into queues to reach the more popular suppliers. to the extent that the major wholesalers provide terminals to their customers and/or facilities to accommodate a large number of transmissions, their queues may be minimal. however, it will be interesting to discover how individual publishers will cope with this situation. readers who are interested in receiving copies of order format #3, invoice format #2 or title update format# 1, should write to: book industry study group, inc., 160 fifth ave., new york, ny 10010. there is no charge for these formats. if all three are requested and first class mail is requested, postal costs are billed to the recipient. those interested in active participation on bisac should send a letter to the organization stating that request. finally, those interested in receiving copies of the minutes of the bimonthly meetings held between september and may should send a request, accompanied by a check for thirty-five dollars to the bisg address. hungry for answers in the life sciences? no matter how unusual your search question , the new 1981 810sis search guide can help you find the right answers. in response to a request for references on " people eating insects as food," an information scientist searched 810sis previews online: " ... i wanted a file with a broad subject coverage and wide range of search options. the first step i took in my search strategy was to use the free-text faci lity for the word 'edible' . then i used the keywords insect , insecta, and insects, which i identified from the 810sis search guide. the guide also led me to several biosystematic codes .. .

interacting with computers metaphors convey information, communicate abstractions, and help us understand new concepts. while the nascent field of information behavior (ib) has adopted common metaphors like “berry-picking” and “gap-bridging” for its models, the study of how people use metaphors is only now emerging in the subfield of human information organizing behavior (hiob). metaphors have been adopted in human–computer interaction (hci) to facilitate the dialogue between user and system. exploration of the literature on metaphors in the fields of linguistics and cognitive science as well as an examination of the history of use of metaphors in hci as a case study of metaphor usage offers insight into the role of metaphor in human information behavior. editor’s note: this article is the winner of the lita/ ex libris writing award, 2008. o ur world is growing increasingly digital; our entire lives—our interactions, our entertainment, even our personal memories—are mediated by technology. humans have had thousands of years to learn to communicate with each other, largely employing metaphors and analogies to negotiate meaning. our experience communicating with computers is both nascent yet broadening every day with increasing dependency. we must fully understand the role that metaphors play in the exchange of information to facilitate the communication between humans and computers. n metaphors: a definition originally regarded as rhetorical devices, plato abhorred the use of metaphors, arguing that they could convince a man to do the illogical. schön explains that at that time metaphors were considered a “kind of anomaly of language, one which must be dispelled in order to clear the path for a general theory of reference or meaning.”1 aristotle, on the other hand, saw that they provided insight into the items of comparison. “ordinary words convey only what we know already; it is from metaphor that we can best get hold of something new.”2 traditionally the objects in the equation have been called the tenor and the vehicle, but more recently they are referred to as the target and source domains. in the metaphor, “alex is a space cadet,” alex is the tenor or target domain (the abstract or undefined), and space cadet represents the vehicle or source domain (the known). if “the essence of metaphor is understanding and experiencing one thing in terms of another,” then the vehicle or the source domain is responsible for elucidating the tenor or target domain.3 one measures the relationship between these domains, the tenor and the vehicle, with “ground” and “tension.” ground concerns the similarities between the domains and tension represents the dissimilarities.4 metaphors have been studied from multiple perspectives: from the creative use of metaphors in literature to the comprehension or appreciation of metaphors.5 the research from other disciplines can offer insight into the effect of metaphors on human information behavior. i will first discuss the use of metaphors in language and then review some of the theories on how they work. n metaphorically speaking: the role of metaphors in language the work of lakoff and johnson has been fundamental to understanding the pervasive use of metaphors in our language. they propose that metaphors are an underlying structure forming and shaping the way we discuss and even think about the world. they argue that the “human conceptual system is metaphorically structured and defined.”6 mapping from a source domain to a target domain is central to the semantics of language and communication. “domains need structure so that one can reason about them. the major function of metaphor is thus to supply structure in terms of which reasoning can be done.”7 in metaphors we live by, lakoff and johnson catalogue examples of underlying conceptual metaphors. they identify orientation metaphors that underlie how we speak about abstract concepts such as health, happiness, and success. each of these states is associated with the direction up. one can be “up and at ‘em” or in “high spirits” or of “high standing.” counter examples include “being under the weather,” “feeling down,” and “low comedy.” metaphors shape the way we think about the concepts we are describing. for instance, the metaphor “argument is war” (“defending your point of view,” “attacking your opponent’s stance,” and “he shot me down”) may define expectations for “winning” and “losing” and detrimentally shape our ability to negotiate and compromise.8 lakoff and johnson refer also to michael reddy’s 1979 piece, “the conduit metaphor.”9 reddy hypothesizes that linguistically and conceptually we see ideas or meanings as objects, linguistic expressions as containers, and communication as sending. the “receivers” of robin sease (seaser@u.washington.edu) is an mlis candidate at the ischool, university of washington, seattle. 10 information technology and libraries | december 2008 the communication are the information users or seekers. the designers “package their ideas,” “put them down on paper,” and “convey” them to the user who “gets” them or not. reddy argues that this underlying metaphor influences the way we think about the communication process, making information and meaning an object rather than a process, which trivializes the function of the reader or listener.10 metaphors are undeniably central to our ability to communicate and use language, and perhaps more fundamentally, to convey meaning or to infer meaning—to illustrate and explain as well as to identify and to catalog. the role of metaphors in human cognition is still a matter of great debate. n thinking about metaphors: the cognitive role of metaphors information science is at its heart the study of information. if metaphors exist as a necessary component of language—a tool to convey meaning and to transfer information—then metaphors are by necessity a component of information science. understanding how metaphors work provides insight into information itself. early propositions about how metaphors were understood stemmed from poetic and rhetorical research. that is, if a sentence cannot be interpreted literally, then it must be interpreted figuratively. to illustrate, the assertion “my child is a pig” is initially illogical, so the receiver would then move on to figurative interpretation. once that determination is made, the mind sets about finding meaning from the expression. this theory argues that once the statement is deemed false, the statement is treated like a simile, or a comparison statement, by identifying traits or attributes in the source domain (the pig: sloppy, slovenly, fascinated with mud) that would be applicable to the target domain.11 one group of theorists questions this premise, pointing to sentences that can be interpreted literally and figuratively. one useful example is the statement “my dog is an animal.”12 while this expression is true literally, most would reject the literal interpretation in favor of one that depicts the dog as a ferocious or uncontrollable beast. glucksberg and keysar, among others, seek a model that focuses on the associations between the domains. they hypothesize that metaphors are not “implicit comparisons” but are class-inclusion statements or “assertions of categorization.”13 research in cognitive processing of analogies has shifted from plain association of a is to b where a traits are matched to b traits to a hypothesis that maps from a to b and leads insight into a super-ordinate category that includes both a and b. gentner’s work studying science metaphors in the 1980s is partially founded on this theory. she notes that through “analogical reasoning, learning can result in the generation of new categories and schemas.”14 she is particularly interested in creating ways for computers to interpret figurative expressions. she proposes a structuremapping theory: a system of relations (not just traits) from the source domain to the target domain with a parallelism between the structures that allows for a one-to-one mapping of the domains and relationships. weiner explores a similar tactic with human–computer interaction language processing by prototyping the shared framework. the prototype theory allows for a range of possible predicates and would accommodate greater tension (the differences in a metaphor) in the same way that we can categorize penguins and chickens under the prototype of bird.15 these theories of categorization remain popular today, but still struggle to account for certain things about the way metaphors are comprehended. specifically, take the shakespearean line, “juliet is the sun.” categorization theory does not explain why some attributes like “glowing” and “center of the solar system” are transferred from the source while others such as “nuclear” and “huge” are not.16 this theory also stumbles with novel poetic metaphors like e e cummings’ “the voice of your eyes is deeper than all roses.”17 alternative theorists argue that while the categorization-based theories accommodate the ground (commonality) in a metaphor, they fail to fully explain the effect and purpose of the tension (differences) in the equation. lakoff fervently contends that simplifying conceptual models to mere categorization ignores the unique nature of each specific mapping: each mapping defines an open-ended class of potential correspondences across inference patterns. when activated, a mapping may apply to a novel source domain knowledge structure and characterize a corresponding target domain knowledge structure.18 in other words, each pairing creates new meaning or conceptual frameworks from which other metaphors and meanings can be instantiated. a is to b creates meaning c, rather than a and b are part of c. looking at it from the perspective of lanier, a vocabulary is created upon which we can define even more vocabulary.19 lakoff maintains that the theory of conceptual domains speaks to both the uni-directional nature of metaphors as well as the “systematicity” that allows the interpreter to selectively identify the aspects that are consistent and discard the aspects that are inconsistent with the metaphor.20 more recent work approaches the question from a connectivist point of view, seeking ways to identify an overarching model consistent with and encompassing of other theories. this premise rests on the foundation of metaphor as communication and examines the use of metaphors in conversational contexts. the necessary mutual cognitive environment of the communicators, the metaphor’s role in the information behavior of humans interacting with computers | sease 11 working memory, and the common ground that they find are all of importance, but so are context and motivation as influencing factors. the context in which the statement is made, the place in which it is interpreted, and the motivation of the user to understand the statement combine to affect the meaning that is derived. for instance, the phrase, “i want you to sheepdog this project” could mean something different in the context of a chaotic group of workers than in the context of a core team threatened by competing entities.21 likewise, the relationship of the receiver to the sender could modify the motivation of the receiver to seek meaning beyond the first or easiest interpretation. n classifying metaphors: metaphors in information science these notions of context and user-motivation are not new to the field of information science. at the turn of the century the subfield of information behavior had begun to direct its attention to cognitive psychology, the nature of man–machine dialogue, and to a certain extent the role of metaphor in deciphering and creating meaning. spink investigates human information behavior (hib) from an evolutionary perspective.22 after exploring a wide variety of research in fields, spink and currier performed a qualitative analysis of the information behavior of historical figures. they postulated that modular cognitive architecture makes homo sapiens rare in their ability to think of one thing in terms of another.23 the resulting mapping allows for the creation of new cognitive structures in a similar fashion to lanier’s vocabulary development conjecture. spink and currier’s work launched a new theory of information use, which has led to recent research into metaphor use. in an attempt to model an integrative approach to human information behavior incorporating the everyday life information-seeking and sense-making approach, the information-foraging approach, and the problem-solution view of information seeking, spink and cole recognized a gap in the research covering actual information use and proffered a fourth information approach to account for it. their information-use theory “starts from an evolutionary psychology notion that humans are able to adapt to their environment and survive because of our modular cognitive architecture.”24 development of this theory has birthed a sub-area within the field of human information behavior dubbed human information organizing behavior (hiob) of which the use of metaphors or metaphor instantiation is a necessary component. cole and leide explore the notion of modular cognitive architecture in an attempt to model a cognitive framework for metaphor use in hiob. similar to the categorization theory of metaphor use, they claim that “metaphor instantiation is similar to a form of superordinate category instantiation . . . along with the metaphor comes the structure of the metaphor.”25 following in belkin’s footsteps, they address the problem of a “domain novice attempting to formulate his information need into an effective query to an information retrieval system.”26 they conducted three case studies with the purpose of developing a methodology that researchers can use to “ascertain the efficacy of metaphor instantiation as an information need structuring device.”27 they conclude that metaphor instantiation might help us create systems that more closely resemble the way that humans behave with information: interaction, organization, and retrieval. n metaphors in human–computer interaction: a case study reality bytes while theorists of various fields explored the nature of metaphors, the field of human–computer interaction (hci) found itself thrust into the thick of it. rarely does one intentionally adopt new ideas so whole-heartedly without first considering the ramifications, but the history of hci shows that that is exactly what happened. it began with enthusiastic adoption to improve communication, then reeled in recognition of the drawbacks of metaphor mismatches, and finally has lurched to a standstill while new approaches to metaphor use are explored. the first instances of metaphor and analogy in the field of computer science and hci preceded images of windows, desktops, mice, scrollbars, and icons. the initial focus was on natural language processing to improve the communication between the user and the system.28 although the field of information science was on the periphery of metaphor research at the time, it certainly was interested in improving the dialogue between users and systems. belkin proposed a model of information seeking that highlighted the user ’s anomalous state of knowledge. he argued for a better understanding of user’s conceptual models in order to improve system communications.29 although he did not propose metaphors specifically, the advent of the graphical user interface (gui) placed metaphors in a position to tackle belkin’s concerns. hci gets gui perhaps because of the difficulty of man–machine dialogue, guis emerged. by simplifying the “language” to “point and click,” even an average user could make the system do what it was supposed to do.30 with its more intuitive and memorable interface, the gui was the 12 information technology and libraries | december 2008 result of years of frustration trying to remember system functions and commands. because illustrations of the abstract are necessarily grounded in something concrete, guis and metaphors were inexorably intertwined; in a sense, metaphors were “inescapable.”31 metaphors enacted through the user interface would become the primary mechanism of communication between the user and the system. gui metaphors can be categorized several ways. a typical breakdown is to break out noun and verb metaphors into “organization metaphors” and “operations metaphors.”32 alternatively, fineman further divides the nouns and classifies various metaphors into three basic types: functionality metaphors, interface metaphors, and interaction metaphors.33 fineman describes an e-mail program. functionality metaphors outline the expectations that a user should have for an application and generally guide the overall behavior of the tool. in the e-mail program the functionality metaphor would be “e-mail is postal mail.” interface metaphors are the mechanical metaphors that allow the user to accomplish the tasks within the functionality metaphor. the interface metaphors should be guided by the functionality metaphors, but not constrained by them. examples would include the address book and printer metaphors. interaction metaphors, or the verbs, are the underlying metaphors that define the form of the action, how things are performed; these metaphors span beyond a particular tool, but greatly affect the functionality metaphor.34 the effect of the selected metaphors cannot be underestimated. for instance, many feel that the direct manipulation metaphor (data is an object that can be manipulated) and gui are synonymous.35 and within the graphical user interface, the choice of desktop has affected all aspects of the interface with the user. one need only reflect upon the famous englebart demonstration of the “mouse” most often viewed in alan kay’s video presentation.36 englebart’s mouse preceded the notion of a desktop and more closely resembled a pilot’s controls than an office worker sitting at a typewriter keyboard. imagine how different our computers would be today had the pilot metaphor ever got off the ground.37 the ground we walk on having adopted metaphors, the field of hci wanted a better understanding of why and how they worked. carroll and thomas stressed the importance of psychology research and rallied for the use of metaphor for its grounding purposes, that is, bridging abstract concepts to concrete attributes. in a manner similar to belkin, they brought forth the notion that the designer of the system creates a conceptual model of how it works. the metaphors used within the user interface serve as bridges to the user’s mental model of the system. “people employ metaphors in learning about computing systems, the designers of those systems should anticipate and support likely metaphorical constructions to increase the ease of learning and using the system.”38 they encouraged designers to consider the limitations and consequences of metaphors; ideally, the metaphor should convey its limitations to the user. their eagerness to adopt metaphors, which they considered “crucial” for motivating and facilitating understanding, was countered only by their warning that “for most computer systems there will come a point at which the metaphor or metaphors that initially helped the user understand the system will begin to hinder further learning.”39 case recognized the importance of assessing users’ needs and expectations when designing metaphors for systems. his study of historians found that metaphors and analogies are commonly used in the information behavior of historians. he endorsed their use in interface development despite potential pitfalls. concerned mostly with transitioning historians from physical to electronic format, case argued that digital documents and files should more closely resemble physical files— not necessarily physically but in the manner of retrieval and storage.40 espousing a slightly more conservative opinion, marcus indicated that an “appropriate metaphor balances delicately expectation and surprise on part of the user/viewer.”41 marcus repeated that the objective of the designer is to design a conceptual model that clearly indicates to users what their expectations of the system should be, the goal being that the conceptual model created by the designers will map as much as possible to an existing mental model that the user can bring to reference.42 metaphors are not only useful for familiarizing users with the system, but also affect the system design as part of the design rationale. maclean, bellotti, young, and moran noted the usefulness of metaphors in the creative process, but expressed concern that designers should consider the effect of even implicit metaphors.43 some metaphors are inevitable because “new concepts and processes require new terminology. we can either coin new terms, borrow them from greek, latin, or other languages, create terms by adding prefixes or suffixes—or use metaphoric terms.”44 many metaphors used by designers in their communications are simply embedded in the language of computer science. what makes computer science so unique among the sciences, especially when using metaphors, is that they not only talk about something in terms of metaphors, they implement them too. “we live with our metaphors.”45 this discourse may carry loads of inexplicable metaphors for common users, “heaps” and “stacks” and “parents” and “children,” for instance, come readily to mind for anyone with computer science experience, but do metaphor’s role in the information behavior of humans interacting with computers | sease 13 not necessarily convey meaning to users. we should stay aware of our metaphors so that we avoid seeing “platforms, engines and objects rather than ‘platforms’, ‘engines’ and ‘objects.’”46 the tension builds these caveats that metaphors must be constantly monitored and selected with care, coupled with a growing collection of mismatched and ill-fitting metaphors, began the initial protestations over the use of metaphors in hci. the field of hci started experiencing the effect of the tension in the metaphorical equation—those attributes that fail to match. gentner and nielson summarize three “classic drawbacks” of metaphors: n the target domain has features not in the source domain (magic attributes). n the source domain has features not in the target domain (misleading attributes). n some features exist in both domains but act differently (violation of expectations).47 even proponents of metaphors readily admitted the limits of metaphors, specifically that they never match perfectly and that they can “limit meaning.”48 halasz and moran cautioned that teaching new users through analogical models may be an easy way to introduce a user to a new system but that “analogical models can act as barriers preventing new users from developing an effective understanding of systems.”49 halasz and moran argued that computers are unique; we should abandon analogical models and rather seek to create a conceptual model of the system that would more accurately reflect the actual system. a system designer’s conceptual model would represent the system to improve the user’s ability to solve problems and apply reason within the system. they confess that moving away from analogical models leaves the user without the tool of “prior knowledge,” so for teaching purposes (though not long-term reasoning purposes) they offer the use of smaller, simpler metaphors—those that they liken to literary metaphors used to “make a point in passing. once the point is made, the metaphor can be discarded.”50 noting that there was room for error and rejection on behalf of the user, marcus explained that some inappropriate metaphors simply become assimilated or evolve. for example, the original apple trashcan icon more closely resembled a “kitchen garbage can” for scraps and rotting things than an office wastebasket for paper, but over the years it has evolved to its current office basket icon.51 also, as technology changes, the metaphors will change. “the paradigm shift, or change in metaphors, will be constant and swift as paradigms evolve from prototypes, become typed, evolve to archetypes, and eventually become stereotyped or obsolete.”52 without stating it explicitly, he spoke of dead metaphors: metaphors that no longer bring new meaning to light, the “arm” of a chair or the “leg” of a table, for instance. these metaphors are accepted idiomatically with no need for explanation and exploration. aware of the ease with which users employ idiomatic icons in computing, cooper adduced that idioms and meaningless symbols are preferable to new metaphors, claiming “metaphors offer a tiny boost in learnability to first time users at tremendous cost. the biggest problem is that by representing old technology, metaphors firmly nail our conceptual feet to the ground, forever limiting the power of our software.”53 he proposed that we move away from a metaphoric paradigm to an idiomatic paradigm where a word or symbol simply stands for something else and does not carry with it the weight of analogy. many of the metaphors originally created in computing have become dead metaphors or idioms already. people do not think of their memory buffer where they store copied or cut items as an actual clipboard. the macintosh trashcan is ubiquitously cited as a perfect example of a mismatched metaphor and illustrates what may happen when a metaphor becomes idiomatic. for many years to the horror and confusion of many users, the trashcan both deleted files and was used to eject a diskette. a user would drag their diskette icon to the trashcan to eject it. although this may seem like just a poor choice of metaphor, it does have a sensible origin. historically, computers had no hard drive, but rather ran applications from diskettes. when you were entirely done with the application you would remove the application icon from the desktop by placing it in the trash. you would also need to eject the diskette. for expediency, apple engineers incorporated ejection and desktop removal into one quick task. it was user tested and readily adopted.54 the metaphor was a natural extension until the functionality changed. the user is not the only potential victim of metaphors; the blinders of an adopted metaphor can curtail a system designers’ vision.55 gentner and nielson take great offense at the direct manipulation metaphor because it reduces us to “pointing” and “grunting” as if we were children barely able to communicate or patrons at a restaurant where we don’t speak the language. when they state “computer interfaces must evolve to utilize more of the power of language,”56 they are not speaking of voice control and natural language processing, but to creating a shared language understandable by both the user and the system. only “power users” of a machine have breached the walls of the interface and have attempted to learn the language of the machine itself, but even they are inevitably dragged down by the restrictions of direct manipulation.57 14 information technology and libraries | december 2008 near the end of the millennium, user interface guidelines and handbooks backed off—afraid to support or spurn metaphor use in hci. blackwell’s chronicle of the history of the desktop metaphor notes that 1990 “marked the middle of a decade (1985 to 1995) in which researchers anticipated problems with metaphor at the start and had experienced failure by the end.”58 the silence is most stunning in the handbook of human computer interaction, a 1,582 page volume in which only two of the sixty-two chapters even mention metaphors.59 hollan, bederson, and helfman caution against metaphors in their chapter on information visualization,60 while neale and carroll cautiously return to carroll’s original thesis, stressing the importance of creating a conceptual model (the designer’s model of the system’s functions) that “should incorporate an accurate understanding of the user’s task, requirements, experience, capabilities, and limitations.”61 n metaphor ever after by the year 2000, system designers found themselves stuck between a rock and hard drive. investigations into the efficacy of metaphors find that metaphors are a mixed bag, unavoidable, useful, yet problematic.62 while creating a taxonomy of hci metaphors, barr, biddle, and noble conclude that “the analysis present in the taxonomy should indicate that there are many benefits to user-interface metaphors if we choose them correctly and harness them properly.”63 yet blackwell’s dissertation research finds that metaphors afford “surprisingly little benefit for cognitive tasks” and that the benefit is “largely restricted to mnemonic assistance.”64 blackwell notes that the benefits were greatest when the user constructed his or her own metaphor rather than using the system supplied metaphor. interestingly, while studying students’ understanding of search engines, hendry identified a conceptual metaphor (not provided by the system) common to many of the students’ visions of an information retrieval system. although hendry does not suggest that metaphors should be used when creating systems, he does question how existing conceptual metaphors might be identified through sketching and then incorporated to create mappings “between problem domains and programming notations.”65 endeavoring to incorporate the benefits of metaphors while dodging the drawbacks, recent variations on the use of metaphor have been tendered. neale and carroll lobby for composite metaphors—metaphors made up of multiple metaphors—to alleviate the tension between source and target domains.66 powell found composite metaphors useful for facilitating computer game play without unduly upsetting users. she explains that gamers have readily adopted the tool or inventory bag from which the user may equip their character with a mannequin style “dress-up” panel. the bag and mannequin metaphors have no real-world association but work effectively.67 hsu, investigating composite metaphors, confirmed neale and carroll’s assertions and found that the “closer the mapping between designers’ conceptual models and users’ mental models, the greater the effect of interface metaphors.”68 as an alternative to composite metaphors, khoury and simoff propose a new class of metaphors that they call “elastic.” they explain that metaphors in language are unavoidable, and we must deal with them in information technology. rather than focusing on concrete objects, however, metaphors should focus on social structures, such as relationships in game play. they conclude that “elastic metaphors can provide an optimal mapping from source to target domains.”69 n conclusion historically, in hci the designer of the system supplies metaphors to help the user understand the system better. unfortunately, this format falls prey to reddy’s conduit metaphor: the receiver of the information is left out of the communication process. if hci is to learn from humanto-human interaction, then the user of the system should be able to communicate his or her needs to the system. if the system does not have the capacity to understand the request, then the user and the system should be empowered to select mutually agreeable simple metaphors for communicating. the user should be given the option to choose his or her own metaphors, and the metaphors, vocabulary, and “language” created should be able to evolve as the boundaries of the comparison are reached. a common complaint from users is, “the computer just isn’t listening to me.” and they are, of course, right. the field of information science, and particularly the subfield of human information behavior, are in a unique position to help resolve the long-standing debate over the use of metaphors in hci. from belkin’s early stated objectives to improve information systems to cole and leide’s pursuit of metaphor instantiation in human information organizing behavior, the study of information behavior attempts to better understand and ideally facilitate the user—assisting them in their acquisition and application of information. metaphors are clearly utilized by humans as they communicate with each other, seek and conceptualize information, and solve problems. to improve the interaction between human and computer, we must first gain better insight into the role that metaphors play in our own interaction with information. metaphor’s role in the information behavior of humans interacting with computers | sease 15

library multimedia studio space article supporting faculty’s instructional video creation needs for remote teaching a case study on implementing eglass technology in a library multimedia studio space hanwen dong information technology and libraries | june 2023 https://doi.org/10.6017/ital.v42i2.15201 hanwen dong (hanwendong@uidaho.edu) is instructional technology librarian, university of idaho. © 2023. abstract in 2021, alongside seven colleges at the university of idaho campus, the university of idaho library received an eglass system (https://eglass.io) with funding from the governor’s emergency education relief grant to expand faculty’s capacity to create instructional videos. the eglass is a transparent glass whiteboard that allows instructors to write, draw, and annotate. it comes with a built-in camera that can capture instructors’ facial expressions and gestures while facing their remote students and allow better engagement. the eglass is suitable for creating asynchronous instructional videos for flipped classrooms and integrating zoom for synchronous online classes. this article details the eglass equipment setup, studio space optimization, outreach efforts and initiatives, usage examples of early adopters, lessons learned during the first year of the eglass deployment, and future considerations. introduction in 2021, the university of idaho library (library) received a transparent glass whiteboard called the eglass for faculty to record video-based lectures. the eglass was based on a similar glass whiteboard technology, called the lightboard, that the library already owned. initially built by university of idaho engineering students and later gifted to the library, the lightboard presented challenges to library staff as properly supporting the technology required spending a significant amount of time. offering similar functionalities, the eglass had the potential to also address the issues that the lightboard presented. similar to the lightboard, the eglass allowed instructors to write and draw on the glass while facing their audience, typically students who would be watching the recorded videos later, to provide better engagement. the eglass could also be used for creating asynchronous instructional videos for flipped classrooms and integrating zoom for synchronous online classes. to implement the eglass, it was necessary to consider factors such as the functionality, the space to be occupied, and faculty interest. a year after the original deployment of this tool, the author reports on the lessons learned in this article. lessons including the eglass equipment setup, multimedia studio space optimization, outreach efforts and initiatives, usage examples of early adopters, lessons learned, and future considerations are explored later in this article. background the studio in the university of idaho library provides space and audiovisual equipment to students, faculty, and staff to pursue curricular, personal, and creative multimedia projects. mailto:hanwendong@uidaho.edu https://eglass.io/ https://eglass.io/ information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 2 dong originally converted from a 200-square-foot meeting room, the studio is equipped with a 27-inch imac, a 32-inch full-hd victek monitor, a scarlett 18i20 audio interface, a dbx 266xs 2-channel compressor/gate, two krk’s rokit 5 g3 powered studio monitors, two shure sm58 dynamic vocal microphones with microphone arm stands and pop filters, several portable lights, a green screen, and more. software installed on the imac includes audacity, camtasia, and the essential adobe creative cloud applications such as photoshop, premiere pro, indesign, etc. patrons can use the studio software and equipment to record voice-over narrations and podcasts as well as to edit multitrack audio clips and videos. in addition to using the studio equipment, patrons can also borrow other multimedia equipment, such as video camcorders, audio recorders, tripods, a usb microphone, and a dslr camera, at the circulation desk. initially managed by two library support staff, both of whom left the organization to pursue other opportunities, the studio operations were taken over by the author in 2020. due to the covid-19 pandemic and the lack of air ventilation in the space, the studio was closed in march 2020 and did not reopen until august 2021. while any university-affiliated patron is welcome to use the studio, first-time users were expected to complete an orientation with the author to become familiar with the equipment setup and the audio workflow. to use the studio, patrons had to make reservations, up to two weeks in advance, for up to two hours per day. reservations were made from the studio’s webpage and managed through springshare’s libcal product. patrons who frequented the studio pursued various personal, creative, instructional, and curriculum-related projects, including video recording with the green screen, video editing, podcast recording, voice-over narration recording, etc. the studio was used by patrons several times a week. according to the libcal space statistics, in fall semester 2021, the studio had 48 unique users, 147 total bookings, 211 hours booked, and the average reserved time block was 86 minutes. in spring semester 2022, the studio had 30 unique users, 64 total bookings, 103 hours booked, and the average reserved time block was 97 minutes. a noticeable usage drop in the spring semester was likely due to a reduced number of advertised studio orientations provided to the campus community and fewer classroom assignments that required or promoted studio use. for several years, the studio was home to a lightboard for faculty to record class lectures. designed as open-source hardware by dr. michael peshkin from the mccormick school of engineering at northwestern university, the lightboard was a transparent glass whiteboard illuminated with a built-in light, and the ink would glow in low-light environments. instructors could write and draw on the glass with neon markers while facing the viewers, and the writings and drawings along with the instructor could all be captured in the same frame using a separate camera.1 dr. peshkin provided two solutions for those who were interested in acquiring a lightboard : buying a commercially-produced one or building one from scratch. the lightboard in the studio was built by a group of students in a mechanical engineering class for a senior capstone project as part of a design challenge in partnership with the center for excellence in teaching and learning (cetl), and the students later gifted the lightboard to the library. the lightboard that the studio received came with a steel frame and wheels. the unit’s overall dimensions were 75 inches long, 45 inches wide, and 78 inches high. the glass board itself measured 71.5 by 47.5 inches (see figure 1). information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 3 dong figure 1. the lightboard that the library received. the lightboard was used by a few instructors who frequented the studio over the years. during fall 2019, one faculty member from the college of natural resources regularly used the lightboard two to three times per week for about 45 minutes to an hour per session. another engineering faculty member, whose students built the lightboard, also used the lightboard several times but did not have a regularly scheduled appointment. there had not been any regular users since then. recording videos using the lightboard required a complicated setup. first, instructors would need to gather several pieces of equipment. for instance, they would need to check out a video camera and a tripod at the circulation desk downstairs and a lavalier microphone at the room adjacent to the studio. the setup required the lightboard to be positioned between the instructor and the camera. it was necessary to change the camera setting to flip the video horizontally; otherwise, any writings or drawings in the final recording would be displayed backward. additional steps included starting and stopping the camera recordings, checking throughout the recording process to ensure the instructor’s writing on the lightboard stayed within the camera’s frame of capture, and transferring the media from the camera’s sd card to an external hard drive or to cloud storage. as a result, recording a session using the lightboard required assistance from at least one other individual, usually a library staff or faculty member, from start to finish. the many different information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 4 dong moving parts made the whole experience time-consuming and labor-intensive both for the library staff and the lightboard users. literature review lightboard technology has been implemented at various higher education institutions since 2014. thanks to dr. peshkin, who made the lightboard an open-source technology and provided the building instructions on his website, many institutions built their own versions of lightboards with variable setups. due to the nature of the lightboard requiring a controlled lighting environment and the writing being backwards from the perspective of those facing the glass (including the camera), the lightboards were used almost exclusively in dedicated studio spaces where the videos were to be recorded. for instance, similar to the university of idaho library studio setup, the complete setup at the university of western australia consists of a lightboard, a camera, lights, markers, a lapel microphone, and a black canvas.2 a budget setup that cost as little as $100 as a removable, tabletop version was also developed.3 cornell university came up with a lightboard and projector setup that can be used in a live 500-person auditorium.4 needless to say, the lightboard technology was adaptable enough to meet various needs on many campuses. several studies show that, among the various types of instructional videos for asynchronous learning, students favor lightboard videos. one unique feature of the lightboard technology, for example, is that it enables instructors to incorporate their gaze and gestures into the instruction. according to a 2015 study, combining gaze and gestures with traditional instructional materials proved to be more effective in directing students’ attention.5 in a 2019 study, several researchers analyzed various lightboard cases in the context of learning theories and theoretical frameworks, such as cognitive load theory, cognitive theory of multimedia learning, and social learning theory. the researchers concluded that while more empirical research was needed, the lightboard videos could improve student learning and engagement.6 in another study conducted by researchers at the university of illinois urbana-champaign, students watched two types of recorded lectures—picture-in-picture with the instructor appearing in a corner of the video, or an overlay of the instructor without the background. study results showed that the overlay videos where the instructor interacted with the content had more views and were preferred by the students, likely thanks to the gaze and gestures of the instructor increasing accessibility. 7 in classes in which the instructors opted to use the lightboard, students generally responded positively to the lightboard videos. for example, in two online classes at clayton state university, most students preferred the lightboard lecture over the traditional narrated powerpoint lecture, and “students described it as engaging, more personable, appealing to visual learners, easier to follow and retain the information, and more similar to a conventional live lecture.”8 at bond university, in queensland, australia, in a chemistry class where the lightboard videos were incorporated as a learning aid, researchers reported that over a four-year period, students scored higher on exams in courses in which lightboard videos were incorporated as instructional materials.9 in another example, students enrolled in a physics class at san diego state university were exposed to the learning glass, a commercial product that was based on the lightboard technology. students responded in a post-course assessment that they felt more connected to their instructor when the instructor utilized the learning glass, and thus the researchers argued that the learning glass could positively impact stem students’ retention rates.10 lastly, at georgia southern university, two researchers conducted a mixed-method study to assess different groups of students’ perceptions of lightboard videos. the findings showed that while performing equally information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 5 dong well when comparing test scores, the students in the class that incorporated lightboard videos had better understanding, engagement, and satisfaction based on the assessment measures.11 lightboards are not without their drawbacks given the requirements and the limitations of the equipment and the recording conditions. in an engineering class where students used lightboard for a problem-solving assignment to demonstrate their learning, researchers identified the various requirements including a room with sufficient size, the need for filming equipment, and long postproduction processing time.12 other disadvantages of the lightboard included immobility, limited writing surface, and a more rigorous cleaning process.13 the type of content being presented in lightboard videos also required consideration. in a study comparing different types of lecture videos, students showed a strong preference to the learning glass videos and “suggested that this style be used to supplement lecture videos (in the form of practice problems and follow-up videos).”14 this conclusion corroborated another study that a lightboard was useful for step-by-step problem-solving explanations.15 lastly, in a study that examined three different styles of lightboard videos (interview style, multipresenter, and multimedia-enriched), the researchers identified the benefits along with the drawbacks of each style.16 for example, while interview videos highlighted interactions between the presenter and the interviewer, the presenter experienced “difficulty in multitasking between writing notes on the lightboard and attending to the interviewer’s questions.” having several presenters could also limit the amount of space for them to move around and write on the glass while remaining in frame and created possible distractions of having too many people as well as too much writing on the glass. another potential issue is that not all presenters could be wearing darker-colored clothing for better contrast with the writing. eglass context in spring 2021, the manager at the collaboration & classroom technology services (ccts) department at the university of idaho informed the author that they were planning on purchasing several eglass units for the campus to support faculty’s instructional video creation. the funds came from the governor’s emergency education relief (geer) grant to address the covid-19 pandemic’s impact on higher education. initially, the grant was written by several individuals who intended to purchase commercially-made lightboards to enhance distance teaching options. while researching for the grant, the team stumbled upon the eglass, which seemed to be easier to use than the lightboard. the pricing was reasonable, so the team decided to purchase several of these devices instead of the original two lightboards that were originally recommended. if interested, the library could receive one unit alongside eight other colleges on campus. the author checked out the demo unit at ccts and reported the first impressions as a user to the dean of university of idaho libraries. the latter reasoned that due to the lightboard and eglass’s duplicating functionalities and the fact that the eglass had more perceived ease of use given its all in-one package without the lighting and camera being separate, it would be best to replace the lightboard with the eglass. the author contacted the lightboard capstone project faculty member, who chose to rehome the lightboard to the engineering outreach department at the college of engineering. removing the lightboard paved the way for welcoming the eglass to the studio by reclaiming needed room space. information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 6 dong the eglass came in two sizes—a 35-inch and a 50-inch diagonal writing surface. the library received a 50-inch unit with the writing surface measured at 45.64 inches long and 27.40 inches tall. the height of the overall unit could be adjusted to 29.37 inches, 31.33 inches, or 33.31 inches. additional accessories that the library received included a desktop computer, two heightadjustable desks, a touchscreen monitor, a webcam, a ring light, peripherals, neon pens, and white clothes for wiping down the writings. once the order of the eglass came through, a ccts team that consisted of several individuals brought the eglass along with two height-adjustable tables to assemble (see figure 2). the assembling of all the equipment took about an hour. figure 2. ccts team assembling the eglass; disclosure: the shirt logo does not represent any affiliations. description similar to the lightboard, the eglass was made of a sheet of glass and a frame, and the instructors could write on the glass using neon markers. however, the eglass had several distinct features and advantages over the lightboard. first and foremost, the eglass had a built-in camera and the recording function that enabled the instructors to start, pause, and stop the recording on their own with a touch of a button. in addition, the eglass internal system flipped the image automatically in real time so that instructors did not need to write backward. therefore, using the information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 7 dong eglass would not require additional support from library personnel since the separate camera setup was no longer needed. the eglass’s built-in lights were also an improvement over the lightboard’s lights. the lightboard came with one set of lights on the frame that illuminated the writings on the glass, but it was necessary to set up additional portable lights to ensure the instructors were illuminated as well. the eglass came with two sets of lights—the instructor light illuminated the instructor, and the blue glass lights ensured the ink on the glass would glow for better visibility. each set of lights was controlled by a separate knob to adjust the intensity. moreover, the eglass could be used as a standalone unit for simple tasks that involved writing and drawing on the glass. for example, instructors could start, pause, and stop the recording using the touch buttons located below the writing surface on the frame. instructors could also use the freeto-download eglassfusion software to access additional features, such as taking snapshots; importing powerpoint slides, word documents, pdfs, and other types of media files; removing the imported media’s background color; zooming in and out; and annotating by typing texts and drawing rectangles or arrows. figure 3. a faculty member recording a video with an application overlay. while the eglass was connected to a desktop computer via a usb cable, instructors could bring their own devices to connect to the eglass, which supports windows, macos, and chromebook operating systems. with a laptop connected to the eglass, instructors could use the down loaded and installed eglassfusion software to control what they were sharing on their screens. for instance, on their devices, instructors could use video conference software such as zoom and microsoft teams for synchronous online instruction via screen sharing and could switch from their laptops’ camera to the eglass camera as the output video. in addition, students could see the information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 8 dong writings and drawings on the glass, the instructor’s face, body, gestures, and any programs opened on the instructor’s laptop on the same screen (see example in figure 3). lastly, instructors could choose to use the eglass while sitting down or standing up as the eglass was placed on a height-adjustable desk. the desktop computer, touchscreen monitor, webcam, and ring light enabled a one-button studio setup. instructors could open any video recording software when pressing the button to start a recording and use the touchscreen monitor for zoom whiteboard and camtasia for screencast recording with annotating. outreach the new equipment setup was completed a few weeks before the start of fall semester 2021. ccts sent out an announcement to the university daily newsletter targeted to faculty and staff to advertise that the eglass had been set up at various locations on campus. the author also provided 20 in-person studio orientations sessions, scheduled at 10:00 a.m. and 2:00 p.m. monday–friday during the first two weeks of classes, to campus students, faculty, and staff. prior sign-ups were not necessary, so patrons could simply show up at the orientation time. these orientations provided an overview to patrons unfamiliar with the studio or any pieces of the existing or new equipment. among the 36 patrons who showed up to the orientations, three faculty members were introduced to the eglass and one-button studio. several additional informational and educational workshops were conducted to promote awareness of the eglass. in the fall semester, ccts hosted a workshop introducing the eglass. due to the limited physical space in the studio that could only comfortably accommodate less than five people, the workshop was hosted in a hybrid format with the in-person location in a room adjacent to the studio. participants could choose to attend either via zoom or in person. if attending in person, participants could visit the studio after the workshop to check out the eglass setup and try out the equipment. workshop attendees noticed that the writing on the eglass was difficult to differentiate from the white wall, which served as the background. after the workshop, the author ordered some black wallpaper and applied it to the wall facing the eglass to help improve the contrast. in the 2022 spring semester, the author facilitated an online library workshop to introduce the eglass, its core features, advantages over the traditional white/blackboard or zoom instructions, examples of applicable disciplines to use eglass for instruction, and best practices to five faculty and two staff attendees. another event to promote the eglass was the engineering design expo at the university of idaho college of engineering, an annual event that showcases design projects created by students. this event attracted regional k–12 students, community college students, industry partners, and community partners. the makerfaire, an event that featured makerspace technologies and a drone demonstration, took place on the same day as the expo. due to the perceived impact of eglass and its application to stem instructions, marketing eglass to the stem audience seemed to be a natural fit. thanks to the assembling ease, the author staffed a table at the makerfaire with a smaller eglass unit loaned from another campus location. the author demoed the eglass to passersby, including students, faculty, and community members. lastly, the active learning symposium is an annual event hosted by ccts and cetl at the university of idaho. in 50-minute presentations, instructors shared their teaching strategies to promote active learning in their classrooms. the author reached out to one eglass regular user, information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 9 dong the computer science department chair, to co-present at the symposium to introduce the eglass and showcase some eglass videos created for a computer science class. usage in the 2021–2022 academic year, two faculty members regularly reserved the studio to use the eglass. one faculty member was the chair of the computer science department, and the other person was in the animal, veterinary and food sciences department. after attending an orientation to the equipment, setup, and software, the faculty members reserved the space and recorded on their own a few more times without the need for support from the author or a staff member. one of the initial goals of replacing the lightboard with the eglass was to free up library staff time to support faculty recording lectures, and the author believed that having this new equipment reached this goal. about halfway through the fall semester in 2021, the author added a checkbox for patrons to indicate their intended studio usage when making a reservation on the library website. based on the statistics generated by libcal, in addition to the two faculty members, five students booked the studio to create instructional videos. however, since none of the students reached out to the author directly and the studio was not staffed, it was not possible to confirm if the students used the eglass or any other pieces of equipment in the studio for video creation. regardless, the overall usage of eglass was lower than anticipated, and the author believed that there were several contributing factors. first, the equipment was not properly set up until the end of summer. several faculty who heard of the eglass expressed interest in using it to prepare for fall instruction, but shipping delays prevented the equipment from being delivered and set up in time. moreover, since several other colleges also received the eglass, faculty members who could access a unit at their colleges chose not to check out the library studio location despite the additional equipment and the optimized space to help improve the user experience. lastly, despite the marketing efforts, the author suspected that the majority of campus was still not aware of the existence of the eglass technology, so additional outreach was probably still needed. lessons learned after overseeing the studio with the new eglass equipment for two semesters, the author underestimated the amount of work to promote the eglass—the saying that “if you build it, they will come” does not always ring true. ensuring that the eglass was adopted by more faculty members required a lot of dedicated effort. identifying several early adopters who saw the value of the technology and were willing to advocate for it by spreading the word to their colleagues was key. even then, the author noticed that the two faculty members who had been using the eglass had stopped coming to the studio regularly after several sessions. keeping faculty engaged despite their diminishing interest in using the equipment was an issue that the author did not anticipate or resolve. in the 2022–2023 academic year, the library engaged in an organization-wide reorganization that halted several existing and anticipated work priorities, one of which was conducting studio space and service assessments. in the 2023–2024 academic year, through a collaborative effort with the new department administrator, the author hopes to improve the studio and eglass usage by planning promotional initiatives and resuming assessment activities. the space to place the equipment, on the other hand, was another consideration. while it was decided to put the eglass in the studio so that the lightboard could be replaced, the physical unit of the 50-inch eglass took more space than the original lightboard. occasionally, the author received information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 10 dong requests from patrons who wanted to use the studio to record videos using a green screen. while it was still manageable to set up a green screen in the remaining space, the lack of room made patrons’ recording experience feel cramped and awkward. overall, for a 200-square-foot studio that had a computer desks, audio equipment racks, portable lights, housing the eglass was less ideal than anticipated. moreover, in order for the studio to be optimized for using the eglass, the lighting, sound, and background required permanent adjustments. for example, after the initial setup, the eglass was facing a white wall in the studio. ideally, the background needs to be dark to help contrasting the lighter neon color writings on the glass. possible solutions included installing a black backdrop, painting the wall black, or applying black wallpaper. installing a backdrop with curtains was the most expensive and time-consuming option, and painting the wall would require temporary closure of the studio. the author opted to order black wallpaper from amazon.com to minimize the disruption to studio operations during the regular semester. the wallpaper cost less than a hundred dollars and applying it to the wall only required an hour, but eventually the adhesive started to wear off. the author decided to remove the wallpaper over the summer and contacted the facilities department to paint the wall black, which took time for removing and restoring the equipment in addition to the time for the wall to dry. lighting was another challenge since the eglass required a light-controlled environment. ideally, all the lights in the room should be turned off for patrons who wanted to use the eglass so that the writings and drawings on the glass were highly visible. some fluorescent lights in the studio were emergency lights that could not be turned off by flipping the light switches. the author had to manually disable some of the lights for the eglass users. the last space-related challenge was sound. the eglass came with a built-in microphone that did not require a separate microphone setup. however, the eglass was placed close to the walls in the studio due to a lack of space which caused some reverberations, lowering the overall sound quality. the sound could be improved if patrons used a headset with microphone and connected the headset to the computer dedicated to the eglass. installing acoustic wall panels was another viable option, and the author might consider such an approach if the usage of the eglass grew to justify the equipment purchase. conclusion the eglass technology at the university of idaho library offered an improved instructional video creation experience to the campus community. thanks to the eglass’s easier setup compared to the lightboard and the studio space improvement in terms of the controlled lighting and the black wall, faculty were greatly benefitted from having access to a tool that enabled them to create engaging videos for classes delivered in online and hybrid modalities. however, additional dedicated outreach efforts are needed for a wider campus adoption. at the university of idaho, seven other colleges on campus owned eglass alongside the library, and there has not been any coordinated communications to promote the technology among all locations. while marketing emails and newsletters would work well for most new services, it is the author’s opinion that potential users would better understand the applicability of the eglass to their instruction when they are able to see the physical unit in person. more in-person outreach, such as inviting faculty to the studio or attending departmental faculty meetings to show videos made using eglass, would be of help. information technology and libraries june 2023 supporting faculty’s instructional video creation needs for remote teaching 11 dong for other institutions that might be interested in acquiring an eglass or a similar technology, the author would suggest conducting an environment scan first to determine the campus need. are there faculty on campus who could benefit from this type of technology to achieve their instructional goals? are there any existing spaces on campus that offer comparable services or resources? if the library administration was interested in acquiring the technology for the library, is there an existing space that would be suitable for placing the equipment? would the library invest in the room so that the lights could be fully controlled, sounds could be proofed or dampened, and a background could be darkened? would there be a staff member to be assigned as the dedicated person to support and maintain the technology? the author hopes that this case study presents a myriad of ideas for those considering adopting a technology similar to an eglass at their libraries. endnotes 1 michael peshkin, “lightboard.info,” https://www.lightboard.info/. 2 timothy r. corkish et al., “a

systematic analysis of university libraries, by jeffrey a. raffel and robert shishko. cambridge, mass.: m. i. t. press, 1969. 107 pp. $6.95. . systematic analysis of university libraries is an exciting book, for it is the first rep?rt describing a~plication of cost-benefit analysis to a library. raffel and shishk? ha~e apphed the methodology of cost-benefit analysis to . the m. i. t. l1branes and have produced an admirable description of this. method of research that examines policy making in a system as a cho~ce among alternatives. this work is not a cookbook providing answers denved from principles; it is an exposition of a methodology that produces data used as a basis of decision making. the book employs the case-study technique, with them. i. t. libraries furnish~g ~e raw material for the cases. findings cannot be extrapolated to all hbranes: although they may be applicable in some. for example, raffel and shishko found that 75% of the m. i. t. libraries budget is allocated to res.earch activities in the institution. such findings are inapplicable to small hberal arts colleges, where faculty members do little research. the ,purpose of systematic analysis of university libraries is to teach the ~ppl1cabo~ of cost-benefit analysis rather than to provide answers. it mstructs m the methodology for obtaining answers. case. studies pres~nted in the ?ook include selection, acquisitions and catalogm~,. ~mong hbrary operations. also examined are book storage, study facihhes and reserve book procedures. a technique for measuring benefits by surveying users is also described. the conc~uding ~hapter presents in outline form major findings, of which o~ly two will be given here as examples of results of this type of analysis. frrst, the authors found that the most effective alternate storage system, namely compact storage, saves only about one percent of annual library resources, but provokes a major loss of benefit, since compact storage limits browsing and increases retrieval time for books. a second finding of int~rest ~s . that major. cataloging expenses are for professional librarians domg ongmal catalogmg, and for proofreading and checking of catalog car~s. t?at costs of original cataloging bulk largest will not be a surprise to hb:anans, but that the ~ext largest cost should be proofreading and checkmg of catalog cards will come as a surprise to some. the book concludes with a score of research questions to be explored in the future, and it is fervently to be hoped that raffel and shishko will continue their

(p. 75.) other pronouncements are patently absurd, such as: "one common use of such real-time 'on-line' computing is the writing of a program directly at the console, instruction l;ly instruction, instead of having to write it all beforehand and read it in from cards or paper tape." ( p. 10.) it is all too easy to fault a short book for shortcomings, but other books in this same series, such as j. m. foster's list processing, have proven the excellence possible in a trim so-shilling monograph (mr. foster's work is only 54 pages.) excellence in this format appears to require focus upon a narrow subject area, and discipline in the treatment of the core elements of the area. in attempting in 84 pages to cover several subjects of encyclopedic scope (library and information systems, as well as a basic computer tutorial), the author piles pelion upon ossa and then shows us sample pebbles from the pile instead of the view from the summit. there remains much important and exciting material to be presented to librarians and computer people about each other's work. regrettably, mr. henley, in the words of his fellow dubliner james joyce, has "speared the rod and spoiled the lightning." wiuiam r. nugent a candid look at collected works: challenges of clustering aggregates in glimir and frbr gail thornburg information technology and libraries | september 2014 53 abstract creating descriptions of collected works in ways consistent with clear and precise retrieval has long challenged information professionals. this paper describes problems of creating record clusters for collected works and distinguishing them from single works: design pitfalls, successes, failures, and future research. overview and definitions the functional requirements for bibliographic records (frbr) was developed by the international federation of library associations (ifla) as a conceptual model of the bibliographic universe. frbr is intended to provide a more holistic approach to retrieval and access of information than any specific cataloging code. frbr defines a work as a distinct intellectual or artistic creation. put very simply, an expression of that work might be published as a book. in frbr terms, this book is a manifestation of that work.1 a collected work can be defined as “a group of individual works, selected by a common element such as author, subject or theme, brought together for the purposes of distribution as a new work.”2 in frbr, this type of work is termed an aggregate or “manifestation embodying multiple distinct expressions .”3 zumer describes aggregate as “a bibliographic entity formed by combing distinct bibliographic units together.”4 here the terms are used interchangeably. in frbr, the definition of aggregates applies only to group 1 entities, i.e., not to groups of persons or corporate bodies. the ifla working group on aggregates has defined three distinct types of aggregates: (1) collections of expressions, (2) aggregates resulting from augmentation or supplementing of a work with additional material, and (3) aggregates of parallel expressions of one work in multiple languages.5 while noting the relationships between the categories, this paper will focus on the first type. aggregates of the first type include selections, anthologies, series, books with independent sections by different authors, and so on. aggregates may occur in any format, from a volume containing both of the j. d. salinger works catcher in the rye and franny and zooey to a sound recording containing popular adagios from several composers to a video containing three john wayne movies. gail thornburg (thornbug@oclc.org) is consulting software engineer and researcher at oclc, dublin, ohio. mailto:thornbug@oclc.org a candid look at collected works | thornburg 54 the environment the oclc worldcat database is replete with bibliographic records describing aggregates. it has been estimated that that database may contain more than 20 percent aggregates.6 this proportion may increase as worldcat coverage of recordings and videos tends to increase. in the global library manifestation identifier (glimir) project, automatic clustering of the records into groups of instances of the same manifestation of a work was devised. glimir finds and groups similar records for a given manifestation and assigns two types of identifiers for the clusters. the first type is manifestation id, which identifies parallel records differing only in language of cataloging or metadata detail, some of which are probably true duplicates whose differences cannot be safely deduplicated by a machine process. the second type is a content id, which describes a broader clustering, for instance, physical and digital reproductions and reprints of the same title from differing publishers. this process started with the searching and matching algorithms developed for worldcat. the glimir clustering software is a specialization of the matching software developed for the batch loading of records to worldcat, deduplicating the database, and other search and comparison purposes.7 this form of glimirization compares an incoming record to database search results to determine what should match for glimir purposes. this is a looser match in some respects than what would be done for merging duplicates. the initial challenges of tailoring matching algorithms to suit the needs of glimir have been described in thornburg and oskins8 and in gatenby et al.9 the goals of glimir are (1) to cluster together different descriptions of the same resource and to get a clearer picture of the number of actual manifestations in worldcat so as to allow the selection of the most appropriate description, and (2) to cluster together different resources with the same content to improve discovery and delivery for end users. according to richard greene, “the ultimate goal of glimir is to link resources in different sites with a single identifier, to cluster hits and thereby maximize the rank of library resources in the web sphere.”10 glimir is related conceptually to the frbr model. if the goal of frbr is to improve the grouping of similar items for one work, then glimir similarly groups items within a given work. manifestation clusters specify the closest matches. content clusters contain reproductions and may be considered to represent elements of the expression level of the frbr model. the frbr and glimir algorithms this paper discusses have evolved significantly over the past three years. in addition, it should be recognized that the frbr algorithms use a map/reduce keyed approach to cluster frbr works and some glimir content while the full glimir algorithms use a more detailed and computationally expensive record comparison approach. the frbr batch process starts with worldcat enhanced with additional authority links, including the production glimir clusters. it makes several passes through worldcat, each pass constructing keys that pull similar records together for comparison and evaluation. as described by toves, “successive passes progressively build up knowledge about the groups allowing us to refine and information technology and libraries | september 2014 55 expand clusters, ending up with the work, content and manifestation clusters to feed into production.”11 each approach to clustering has its limits of feasibility, but the frbr and glimir combined teams have endeavored to synchronize changes to the algorithms and to share insights. some materials are easier to cluster using one approach, and some in the other. clustering meets aggregates in the initial implementation of glimir, the issue of handling collected works was considered out of scope for the project. with experience, the team realized there can be no effective automatic glimir clustering if collected works are not identified and handled in some way. why is this? suppose a record exists for a text volume containing work a. this matches to a record containing work a, but actually also containing work b. this matches to a work containing b and also containing works c, d, and e. the effect is a snowballing of cluster members that serves no one. how could this happen? in a bibliographic database such as worldcat, items representing collected works can be catalogued in several ways. efforts to relax matching criteria in just the right degree to cluster records for the same work are difficult to devise and apply. the glimir and frbr teams consulted several times to discuss clustering strategies for works, content, and manifestation clusters. practical experience with glimir led to rounds of enhancements and distinctions to improve the software’s decisions. while glimir clusters can and have been undone and redone on more than one occasion, it took experience from the team to realize that the clues to a collected work must be recognized. bible and beowulf as are many initial production startups, the output of glimir processing was monitored. reports for changes in any clusters of more than fifty were reviewed by quality control catalogers for suspicious combinations. and occasionally a library using a glimiror frbr-organized display would report a strange cluster. this was the case with a huge malformed cluster of records for the bible. such a work set tends to be large and unmanageable by nature; there are a huge number of records for the bible in worldcat. however, it was noticed the set had grown suddenly over the previous two months. user interface applications stalled when attempting to present a view organized by such a set. one day, a local institution reported that a record for beowulf had turned up in this same work set. this started the team on an investigation. after much searching and analysis of the members of this cluster, the index case was uncovered. in many cases bibliographic records are allowed to cluster based on a uniform title. what the team found connecting these disparate records was a totally unexpected use of the uniform title, a field a candid look at collected works | thornburg 56 240 subfield a, contents: “b.”. that’s right, “b.”. once the first case was located, it was not hard to figure out that there were numerous uniform “titles” with other single letters of the alphabet. so in this odd usage, bible and beowulf could come together, if insufficient data were present in two records to discriminate by other comparisons. or potentially, other titles which started with “b.” seeing this unanticipated use of uniform title field, the frbr and glimir algorithms were promptly modified to beware. the frbr and glimir clusters were then unclustered and redone. this was a data issue, and unanticipated uses of fields in a record will crop up, if usually with less drama. further experience showed more. in the examination of another ill-formed cluster, a reviewer realized that one record had the uniform title stated as “illiad” but the item title was homer’s “odyssey.” of course these have the same author, and may easily have the same publisher. even the same translator (e.g., richard lattimore) is not improbable for a work like this. this was a case of bad data, but it imploded two very large clusters. music and identification of collected works as music catalogers know, musical works are very frequently presented in items that are collections of works. the rules for creating bibliographic records for music, whether scores or recordings or other, are intricate. the challenges to software to distinguish minor differences in wording from critical differences seem to be endless. moreover, musical sound recordings are largely collected works due to the nature of publication. as noted by papakhian, personal author headings are repeated oftener in sound recording collections than in the general body of materials.12 there are several factors that may contribute to such an observation. there are likely to be numerous recordings by the same performer of different works and numerous records of the same work by different performers. composers are also likely to be performers. the point is, for sound recordings an author statement and title may be less effective discriminators than for printed materials. vellucci13,14 and riley15 have written extensively on the problems of music in frbr models. the problems of distinguishing and relating whole/part relationships is particularly tricky. musical compositions often consist of units or segments that can be performed separately. so they are generally susceptible to extraction. these extractive relationships are seen in cases where parts are removed from the whole to exist separately, or perhaps parts for a violin or other instrument are extracted from the full score. software must be informed with rules as to significant differences in description of varying parts and varying descriptions of instruments, and in this team’s experience that is particularly difficult. krummel has noted that the bibliographic control of sound recordings has a dimension beyond item and work, that is, performance.16 different performances of the same beethoven symphony information technology and libraries | september 2014 57 need to be distinguished. cast and performer list evaluation and dates checking are done by the software. however, the comparisons the software can make are susceptible to fullness or scarcity of data provided in the bibliographic record. there is great variation observed in the numbers of cast members stated in a record. translator and adapter information can prove useful in the same sense of roles discrimination for other types of materials. this is close scrutiny of a record. at the same time consider that an opera can include the creative contributions of an author (plot), a librettist, and a musical composer. yet these all come together to provide one work, not a collected work. tillett has categorized seven types of bibliographic relationships among bibliographic entities, including the following: 1. equivalence, as exact copies or reproduction of a work. photocopies, microforms are examples. 2. derivative relationships, or, a modification such as variations, editions, translations. 3. descriptive, as in criticism, evaluation, review of a work. 4. whole/part, such as the relation of a selection from an anthology. 5. accompanying, as in a supplement or concordance or augmentation to a work. 6. sequential, or chronological relationships. 7. shared characteristic relationships, as in items not actually related that share a common author, director, performer, or other role. 17 while it is highly desirable for a software system to notice category 1 to cluster different records for the same work, that same software could be confused by “clues,” such as in category 7. and the software needs to understand the significance of the other categories in deciding what to group and what to split. to handle these relations in bibliographic records, tillett discusses linking devices including, for instance, uniform titles. yet uniform titles are used for the categories of equivalence relationships, whole/part relationships, and derivative relationships. this becomes more and more complex for a machine to figure out. of course, uniform titles within bibliographic records are supposed to link to authority records via text string only. consideration should ideally be given to linking via identifiers, as has been suggested elsewhere.18 thematic indexes review of scores and recordings glimir clusters showed a case where haydn’s symphonies a and b were brought together. these were outside the traditional canon of the 104 haydn symphonies and were referred to as “a” and “b” by the haydn scholar h. c. robbins landon. this misclustering highlighted the need for additional checks in the software. a candid look at collected works | thornburg 58 the original glimir software was not aware of thematic indexes as a tool for discrimination. thematic indexes are numbering systems for the works of a composer. the kochel mozart catalog, as in k. 626, is a familiar example. these designations are not unique to a given composer, that is, they are intended to be unique for a given composer, but identical designators may coincidentally have been assigned to multiple composers. while “b” series numbers may be applied to works of chambonnières, couperin, dvořák, pleyel, and others, the presence of more than one b number is suggestive of collected work status. for more on the various numbering systems, see the interesting discussion by the music library association.19 however, the software cannot merely count likely identifiers in the usual place. this could lead to falsely flagging aggregates; one work by dvořák could have b.193, which is incidentally equivalent to opus 105. clearly, any detection of multiple identifiers of this sort must be restricted to identifiers of the same series. string quartet number 5, or maybe 6 cases of renumbering can cause problems in identifying collected works. an early suppressed or lost work, later discovered and added to the canon of the composer’s work, can cause renumbering of the later works. clustering software needs must be very attentive to discrete numbers in music, but can it be clever enough? paul hindemith (1895–1963) works offer an example. his first string quartet was written in 1915, but long suppressed. his publisher was generally schott. long after hindemith’s death, this first quartet was unearthed, and then was published by schott. the publisher then renumbered all the quartets. so quartets previously 1 through 6 became 2 through 7. the rediscovered work was then called “no. 1,” though sometimes called “no. 0” to keep the older numbering intact. further, the last two quartets did not even have opus numbers assigned and were both in the same key.20 this presents a challenge. anything musical another problem case emerged when reviewers noticed a cluster contained both the unrelated songs “old black joe” and “when you and i were young maggie.” on investigation, the cluster held a number of unrelated pieces. here the use of alternate titles in a 246 field had led to overclustering, and the rules for use of 246 fields were tightened in frbr and glimir. as in the other problem cases, cycles of testing were necessary to estimate sufficient yet not excessive restrictions. rules too strict split good clusters and defeat the purpose of frbr and glimir. at this point the glimir/frbr team recognized that rules changes were necessary but not sufficient. that is, a concerted effort to handle collected works was essential. information technology and libraries | september 2014 59 strategies for identifying collected works the greatest problem, and most immediate need, was to stop the snowballing of clusters. clusters containing some member records that are collected works can suddenly mushroom out of control. rule 1 was that a record for a collected work must never be grouped with a record for a single work. if all in a group are collected works, that is closer to tolerable (more on that later). with time and experimentation, a set of checks were devised to allow collected works to be flagged. these clues were categorized as types: (1) considered conclusive evidence, or (2) partial evidence. type 2 needed another piece of evidence in the record. finding the best clues was a team effort. it was acknowledged that to prevent overclustering, overidentification of aggregates was preferable to failure to identify them. several cycles of tests were conducted and reviewed, assessing whether the software guessed right. table 1 illustrates the types of checks done for a given bibliographic record. here the “$” is used as abbreviation for subfield, and “ind” equals indicator. area field rule notes uniform title 240 $a and no $m, $n, $p, or $r title in $ a on list of terms, without the other subfields listed, is collected work this is a long list of terms such as “symphonies,” “plays,” “concertos,” and so on. title 245 contains “selections,” is collected 245 245 with multiple semi colons and doc type “rec” 246 if four or more v246 fields with ind2 = 2, 3, or 4, is collected. if more than 1 246, consider partial evidence extent 300 if 300$a has “pagination multiple” or “multiple pagings,” is collected contents notes 505$a and $t 1. check $a for first and last occurrences of “movement”. if not multiple movement occurrences and does have if all / any the above produce more than one pattern instance or more a candid look at collected works | thornburg 60 multiple “ / ” pattern. 2. if the above doesn’t find multiple patterns, also look for “ ; “ patterns. 3. if the above checks don’t produce more than 1 pattern, look for multiple “ – ” patterns. 4. count 505s $t cases. 5. count $r cases. than one $t, or more than one $r, is collected. various fields for thematic index clues 505a if any v505 $a, check for differing opuses. (this also checks for thematic index cases too.) if found, is collected. for types score and recording related work 740 if 1 or more 740 and 1 has indicator 2 = 2”, is collected . if only multiple 740s, partial evidence author 700/710/711/730 check for $t and $n. and check 730 ind 2 value of “2.” if 730 with ind2 = 2 or multiple $t is found, is collected. if only 1 $t, partial evidence 100/110/111, 700/710 730 if format recording, and both records are collected work, require cast list match to cluster anything but manifestation matches. that is, do not cluster at content level without verifying by cast. table 1. checks on bibliographic records. frailties of collected works identification in well-cataloged records the above table illustrates many areas in a bibliographic record that can be mined for evidence of aggregates. the problem is that cataloging practice offers no one rule mandatory to catalog a collected work correctly. moreover, as worldcat membership grows, the use of multiple schemes of cataloging rules for different eras and geographic areas adds to the complexity, even assuming that all the bibliographic records are cataloged “correctly.” correct cataloging is not assumed by the team. information technology and libraries | september 2014 61 software confounded with all the checks outlined in the table, the team still found cases of collected works that seemed to defy machine detection. one record had the two separate works, tom sawyer and huckleberry finn, in the same title field, with no other clues to the aggregate nature of the item. the work brustbild was another case. for this electronic resource set, brustbild appeared to be the collection set title, but the specific title for each picture was given in the publisher field. a cluster for the work gedichte von eduard morike (score) showed problems with the uniform title which was for the larger work, but the cluster records each actually represented parts of the work. the bad cluster for si ku quan shu zhen ben bie ji, an electronic resource, contained records which each appeared to represent the entire collection of 400 volumes, but the link in each 856 field pointed only to one volume in the set. limitations of the present approach the current processing rules for collected works adopt a strategy of containment. the problem may be handled in the near term by avoiding the mixing of collected works with noncollected works, but the clusters containing collected works need further analysis to produce optimal results. for example, it is one thing to notice scores “arrangements” as a clue to the presence of an aggregate. the requirement also exists that an arrangement should not cluster with the original score. the rules for clustering and distinguishing different sets of arrangements present another level of complexity. checks to compare and equate the instruments involved in an arrangement are quite difficult; in this team’s experience, they fail more often than they succeed. without initial explication of the rules for separating arrangements, reviewers quickly found clusters such as haydn’s schopfung, which included records for the full score, vocal score, and an arrangement for two flutes. an implementation that expects one manifestation to have the identifier of only one work is a conceptual problem for aggregates. a simple case: if the description of a recording of bernstein’s mass has an obscurely placed note indicating the second side contains the work candide, mass is likely to be dominant in the clustering effect, with the second work effectively “hidden.” this manifestation would seem to need three work ids, one for the combination, one for mass, and one for candide. this does not easily translate to an implementation of the frbr model but could perhaps be achieved via links. several layers of links would seem necessary. a manifestation needs to link to its collected work. a collected work needs links to records for the individual works that it contains, and vice versa, individual works need to link to collective works. this can be important for translations, for example, into russian, where collective works are common even where they do not exist in the original language. a candid look at collected works | thornburg 62 lessons learned first and foremost, plan to deal with collected works. for clustering efforts this must be addressed in some way for any large body of records. secondly, formats will gain the focus. the initial implementation of the glimir algorithms used test sets mainly composed of a specific work. after all, glimir clusters should all be formed within one work. these sets were carefully selected to represent as many different types of work sets as possible, whether clear or difficult examples of work set members. plenty of attention was given to the compatibility of differing formats, given the looser content clustering. these were good tests of the software’s ability to cluster effectively and correctly within a set that contained numerous types of materials. random sets of records were also tested to cross check for unexpected side effects. what in retrospect the team would have expanded was sets that were focused on specific formats. recordings, scrutinized as a group, can show different problems than scores or books. the distinctions to be made are probably not complete. another lesson learned in glimir concerned the risks of clustering. the deliberate effort to relax the very conservative nature of the matching algorithms used in glimir was critical to success in clustering anything. singleton clusters don’t improve anyone’s view. in the efforts to decide what should and should not be clustered, it was initially hard to discern the larger scale risks of overclustering. risks from sparse records were probably handled fairly well in this initial effort, but risks from complex records needed more work. collected works is only one illustration of risks of overclustering. future research the current research suggests a number of areas for possible further exploration: • the option for human intervention to rearrange clusters not easily clustered automatically would seem to be a valuable enhancement. • there is next the general question, what sort of processing is needed, and feasible, to distinguish the members of clusters flagged as collected works? • part versus whole relationships can be difficult to distinguish from the information in bibliographic records. further investigation of these descriptions is needed. • arrangements of works in music are so complex as to suggest an entire study by themselves. work on this area is in progress, but it needs rules investigation. • other derivative relationships among works: do these need consideration in a clustering effort? can and should they be brought together while avoiding overclustering of aggregates? • how much clustering of collected works may actually be helpful to persons or processes searching the database? how can clusters express relationships to other clusters? information technology and libraries | september 2014 63 conclusion clustering bibliographic records in a database as large as worldcat takes careful design and undaunted execution. the navigational balance between underclustering and overclustering is never easy to maintain, and course corrections will continue to challenge the navigators. acknowledgments this paper would have been a lesser thing without the patient readings by rich greene, janifer gatenby, and jay weitz, as well as their professional insights and help in clarifying cataloging points. special thanks to jay weitz for explicating many complex cases in music

editorial board thoughts: building a culture of resilience in libraries editorial board thoughts building a culture of resilience in libraries paul swanson information technology and libraries | september 2021 https://doi.org/10.6017/ital.v40i3.13781 paul swanson (swans062@umn.edu) is technology manager, minitex, and a member of the ital editorial board © 2021. we find ourselves a year and a half into the global pandemic, and libraries—just like the rest of the workforce—have been navigating through a drastic amount of change in a short amount of time with no real guideposts as to what may come next. libraries were completely shut down, library staff displaced, and library services transformed in a short period of time like they hadn’t been before. we’ve also found that as we’ve reopened our libraries there are new patron and staff expectations. it is expected that the changes that we’ve enacted in the middle of a crisis will continue and will be folded into a new service delivery model. patrons have different expectations of libraries; library staff have different expectations of management and of the technology that drives library services and their day-to-day work. in order to meet these new expectations, we’ve embarked on a path of implementing more flexibility into our environments and workflows. i feel however that the concept of flexibility misses the mark. flexibility is about being open to change and reacting to it, and possibly taking different paths to solving a common problem. flexibility though is part of a broader concept that i think we need to embrace, and that is resiliency. resiliency is defined as “tending to recover from or adjust easily to misfortune or change.”1 we’ve all reacted and persevered through the last year and a half in our own way, but i would bet that those organizations that have a culture of resiliency have fared better. organizations that pride themselves on their flexibility can sometimes be more reactionary than anything. a problem arises and they may be quick to change, to flex and react. a resilient organization can make the conscious decision to absorb the problem, make a change that can be rolled back when the time is right, or even make it permanent. they have built a resilient foundation across the organization that allows them to not just be flexible when a problem arises, but instead assimilate the solutions to the challenges that come up. flexibility is what you do, resilience is what you are. to be more resilient with the technology that your library uses and depends on, is really rather easy. it means doing all those things that you have always meant to do but haven't made the time for. you are building that foundation that your organization can rely on when change or misfortune strikes. that foundation is what enables you to make positive change through a crisis. it is what can keep you from making reactionary decisions. let’s talk through a few of the different places where you can instill resilience in your organization. the stronger your change management practices are, the more resilient your technology will be. all the way from governance for changes, to documentation around decision making, and to a detailed history of the changes that have been made to your systems. it sounds like a lot because it is a lot, but you have to start now. you need to be able to think beyond today’s current state of your systems and understand where you were in the past, and how you got to where you are today. you cannot effectively make changes to your systems, especially in the midst of a crisis, if you don’t know why you’ve done the things you’ve done up to this point. you also need that disaster recovery plan that you’ve always meant to start and keep updated. think of a disaster recovery plan as a set of decisions that have already been made so you have the latitude to act in a crisis without the usual bureaucracy of change governance. in your disaster recovery plans, make mailto:swans062@umn.edu information technology and libraries september 2021 building a culture of resilience in libraries | swanson 2 sure you have defined roles for everyone who is involved. make sure that communication has just as important of a role as resolving the crisis at hand. you need to finish that disaster recovery plan and keep it updated if you are going to instill resilience into your technology and organization. when it comes down to building resilience in the decisions that you are making, you need to start integrating the concept of two-way decision making into your process.2 a two-way decision is reversible. yes, most decisions that we make feel like a one-way street. anything from starting a new service, applying for a grant, or purchasing a new technology platform. but we can temper this by applying two-way decision making to the implementation decisions for the project or activity that we are undertaking. even if you just plan on ways to mitigate the impact of a decision gone wrong, you are building resilience into your decision-making process. you should also go beyond asking “how can we roll this decision back?” by having discussions around “what are the impacts this decision might have that would cause us to roll it back?” defining those evaluation metrics before you embark on a path can help to make your decisions more resilient. if you think about decisions as a two-way door and incorporate both the how and the why into them, you will be on your way to having a much more resilient change management process. when it comes to building resilience into our day-to-day workflows, we have to paradoxically standardize how we do work. if we are going to be more flexible and absorb change, it would be reasonable to think that we should support many different ways of working. however, that type of work fragmentation doesn’t scale to a hybrid work environment. it is just too much to try to support a work environment where common tasks are performed differently by staff that are physically located almost anywhere. therefore, we need to standardize how we work in order to support a hybrid work environment. staff communications and expectations need to be the same for every single staff member. everyone uses instant messaging or no one does. everyone keeps their calendar up to date. meetings are held with the same expectations whether a one-on-one with a supervisor or a team brainstorming session. this is foundational to incorporating resilience into the organization. you need to be able to rely on consistent communication channels when a crisis is thrust upon you. workflows that have been traditionally on-premise all need to be reenvisioned into cloud-based processes. work needs to be performed from anywhere, and the only way you can do that effectively is by standardizing how that work is accomplished. the more exceptions that you allow to this, the more you will run into problems with change. this type of standardization has to be ingrained into the culture of the organization with a top -down approach. therefore, it is imperative that those at the top of the library’s org chart embody this standardization. building this type of operational resilience will go a long way towards having that strong foundation that you can rely on across your organization. through the pandemic, many libraries focused on core services, reimagining them so they can function in new ways during the crisis. pandemic-prompted services that may well be permanent include increased use of pop-up libraries and bookmobiles, low-touch self-service kiosks, and webinar-based story times, among others.3 these are the types of changes and decisions that are upon us right now and may very well take up all of the oxygen in the room. however, we still need to make sure that we dedicate resources to that next thing. we can’t overcorrect and only circle the wagons around the delivery of our core services. we have future challenges that we will have to meet. the seeds of the solutions to those challenges may be growing right now in an open source project, a new resource sharing standard, or an innovative use of blockchain. even if, in the end, you don’t take on those projects, you will help build resilience into your library by expanding awareness and understanding. just as the speed of societal change always seems to be increasing, information technology and libraries september 2021 building a culture of resilience in libraries | swanson 3 the speed of expectations for libraries will be increasing. we have to make sure that we continue to dedicate resources into understanding, researching, and building those new services that are only now on the horizon. none of the things that i’ve said are new or groundbreaking. the urgency is what is new. delivery of library services has permanently changed over the past 18 months. how work gets done has permanently changed as well. the only way that we will be able to contend with this new paradigm is to do all of those things that we know we should be doing. shore up your foundations. absorb the change that has happened and will continue to happen. don’t be reactionary or fight for your own personal work needs. be confident problem solvers and work together for the strength of your library and for the needs of your patrons. instill resilience in the work that you do and the services that your library provides and it will help you to endure through whatever may come next. endnotes 1

2008 mireia ribera turróeditorial board thoughts the june issue of ital featured a new column enti-tled editorial board thoughts. the column features commentary written by ital editorial board members on the intersection of technology and libraries. in the june issue kyle felker made a strong case for gerald zaltman’s book how customers think as a guide to doing user-centered design and assessment in the context of limited resources and uncertain user needs. in this column i introduce another factor in the library–it equation, that of rapid technological change. in the midst of some recent spring cleaning in my library i had the pleasure of finding a report documenting the current and future it needs of purdue university’s hicks undergraduate library. the report is dated winter 1995. the following summarizes the hicks undergraduate library’s it resources in 1995: [the library] has seven public workstations running eight different databases and using six different search software programs. six of the stations support a single database only; one station supports one cd-rom application and three other applications (installed on the hard drive). none of the computers runs windows, but the current programs do not require it. five stations are equipped with six-disc cd-rom drives. we do not anticipate that we will be required to upgrade to windows capability in the near future for any of the application programs. today the hicks undergraduate library’s it resources are dramatically different. as opposed to seven public workstations, we have more than seventy computers distributed throughout the library and the digital learning collaboratory, our information commons. this excludes forty-six laptops available for patron checkout and eighty-eight laptops designated for instructional use. we have moved from eight cd-rom databases to more than four hundred networked databases accessible throughout the purdue university libraries, campus, and beyond. as a result, there are hundreds of “search software programs”—doesn’t that phrase sound odd today?—including the library databases, the catalog, and any number of commercial search engines like google. today all, or nearly all, of our machines run windows, and the macs have the capability of running windows. in addition to providing access to databases, our machines are loaded with productivity and multimedia software allowing students to consume and produce a wide array of information resources. beyond computers, our library now loans out additional equipment including hard drives, digital cameras, and video cameras. the 1995 report also includes system specifications for the computers. these sound quaint today. of the seven computers six were 386 machines with processors clocking in at 25 mhz. the computers had between 640k and 2.5mb of ram with hard drives with capacities between 20 and 60mb. the seventh computer was a 286 machine probably with a 12.5 mhz processor, and correspondingly smaller memory and hard disc capacity. the report does not include monitor specifications, though, based on the time, they were likely fourteenor fifteen-inch cga or ega cathode ray tube monitors. modern computers are astonishingly powerful in comparison. according to a member of our it unit, the computers we order today have 2.8 ghz dual core processors, 3gb of ram, and 250gb hard drives. this equates to being 112 times faster, 1,200 times more ram, and hard drives that are 4,167 times larger than the 1995 computers! as a benchmark, consider moore’s law, a doubling of capacitors every two years, a sixty-four fold increase over a thirteen year period. who would have thought that library computers would outpace moore’s law?! today’s computers are also smaller than those of 1995. our standard desktop machines serve as an example, but perhaps not as dramatically as laptops, mini-laptops, and any of the mobile computing machines small enough to fit into your pocket. monitors are smaller, though also bigger. each new computer we order today comes standard with a twenty-inch flat panel lcd monitor. it is smaller in terms of weight and overall size, but the viewing area is significantly larger. these trends are certainly not unique to purdue. nearly every other academic library could boast similar it advancements. with this in mind, and if moore’s law continues as projected, imagine the computer resources that will be available on the average desktop machine— although one wonders if it will in fact be a desktop machine—in the next thirteen years. what things out on the distant horizon will eventually become commonplace? here the quote from the 1995 report about windows is particularly revealing. what things that are currently state-of-the-art will we leave behind in the next decade? what’s dos? what’s a cd-rom? will we soon say, what’s a hard drive? what’s software? what’s a desktop computer? in the last thirteen years we have also witnessed the widespread adoption and proliferation of the internet, the network that is the backbone for many technologies that have become essential components of physical and digital libraries. earlier this year, i co-authored an arl spec kit entitled social software in libraries.1 the survey reports on the usage of ten types of social software within arl libraries: (1) social networking

(95% of respondents) said they are using social software. of the three libraries not using social software, two indicated they plan to do so in the future. in combination then, 63 out of 64 respondents (98%) indicated they are either currently using or planning to use social software. as part of the survey there was a call for examples of social software used in libraries. of the 370 examples we received, we selected around 70 for publication in the spec kit. the examples are captivating and they illustrate the wide variety of applications in use today. of the ten social software applications in the spec kit, how many of them were at our disposal in 1995? by my count three: chat and instant messenger services, voip, and virtual worlds such as text-based muds and moos. of these three, how many were in use in libraries? very few, if any. in our survey we asked libraries for the year in which they first implemented social software. the earliest applications were cu-seeme, a voip chat service at cornell university in 1996, im at the university of california riverside in 1996 as well, and interoffice chat at the university of kentucky in 1998. the remaining libraries adopted social software in year 2000 and beyond, with 2005 being the most common year with 22 responses or 34% of the libraries that had adopted social software. a look at this data shows that my earlier use of a thirteen-year time period to illustrate how difficult it is to project technological innovations that may prove disruptive to our organizations is too broad a time frame. perhaps we should scale this back to looking at five-year increments of time. using the spec kit data, in year 2003, a total of 16 arl libraries had adopted social software. this represents 25% of the total number of institutions that responded when we did our survey. this seems like figure 1. responses to the question, “please enter the year in which your library first began using social software” (n=61). a more reasonable time frame to be looking to the future. so, what does the future hold for it and libraries, whether it be thirteen or five years in the future? i am not a technologist by training, nor do i consider myself a futurist, so i typically defer to my colleagues. there are three places i look to for prognostications of the future. the first is lita’s top technology trends, a recurring discussion group that is a part of ala’s annual conference sand midwinter meetings. past top technology trends discussions can be found on lita’s blog (www.ala .org/ala/lita/litaresources/toptechtrends/toptechnology.cfm) and on lita’s website (www.ala.org/ala/lita/ litaresources/toptechtrends/toptechnology.cfm). the second source is the horizon project, a five-year qualitative research effort aimed at identifying and describing emerging technologies within the realm of teaching and learning. the project is a collaboration between the new media consortium and educause. the horizon project website (http://horizon.nmc.org/wiki/main_page) contains the annual horizon reports going back to 2004. a final approach to project the future of it and libraries is to consider the work of our peers. the next library innovation may emerge from a sister institution. or perhaps it may take route at your local library first! reference 1. bejune, matthew

by “forever” w hat do we mean when we tell people that we want or intend to preserve content or an object “forever”? a couple of weeks ago, i attended the fall meeting of the preservation and archiving special interest group (pasig) in san francisco. the group, generously sponsored by sun microsystems, is the brainchild of art pasquinelli of sun and michael keller of stanford. first, a confession on my part. since the university of alberta (ua) was one of the founding members of pasig, i had occasion to attend the first several pasig meetings. in the beginning, there were just a handful of—perhaps fewer than ten—institutions represented. it seemed at the first couple of meetings, when the group was still finding its direction, that the content was slim, repetitious, and overly focused on sun’s own solutions in the digital preservation and archiving (dpa) arena. since we had other attendees ably representing ua, i stayed away from the following several meetings. well, pasig has grown up. the attendee list for this meeting boasted nearly two hundred persons representing more than thirty institutions. among the attendees were many of the leading lights in dpa and the profession generally. institutions represented included several north american and european national libraries, as well as arls, memory institutions, and a host of companies and consultants offering a range of dpa solutions. yes, pasig has arrived, and we have art, mike, and sun to thank for this. if i have one real remaining complaint about pasig, it’s that the group is still overly focused on sun’s solutions. true, other vendors such as exlibris and vtls attended, but their solutions don’t compete; rather, they build on sun’s offerings. and while microsoft also was in attendance for the first time, its presentation focused not so much on dpa solutions—it has none—as on a raft of interesting and useful plug-ins whose purpose is to facilitate preservation of content created in microsoft products such as word, excel, powerpoint, etc. other large vendors of dpa solutions—think ibm, for one—remain conspicuously absent. it’s time for sun to do the “right thing” and “open source” pasig. if sun wishes to continue to sponsor pasig by lending administrative and organizational expertise, that would be great. indeed, a leading but not controlling role in pasig would be entirely consistent with the company’s new focus on support of open-source efforts such as mysql, openoffice, and opensolaris. so, what about the title of this editorial? when we talk of digital preservation, just how long are we thinking of preserving an object? ask any twenty specialists in dpa, and chances are that you’ll get at least ten different answers. for some, the timeframe can be as short as five to twenty years. for others, it’s fifty or perhaps one hundred years. at pasig, at least one presenter described an organizational business model that envisions preserving content for five hundred years. and there are even some in our profession who glibly use what one might call “the dpa f-word,” although fortunately none of them seemed to be in attendance at this fall’s pasig what does this mean in a very practical, nuts-and-bolts it sense? chris wood of sun gave a presentation at the 2008 pasig spring meeting in which he estimated that the cost to supply power and cooling alone to maintain a petabyte (1,000 tb) of disk-based digital content for a mere ten years would easily exceed $1 million.1 refining his figures downward somewhat, wood noted a few months later at the following pasig meeting that for a 1 tb drive, the fiveyear estimated power and cooling for 2008–12 could be estimated at approximately $320, or $640,000 per petabyte over ten years, still a considerable sum.2 add to this the costs of migration—consider that a modern spinning disk is generally thought to have a useful lifespan of about five years, and tape may have two or three decades—and the need regular integrity-checking of digital content for “bit-rot,” and you have the stuff of a sustainability nightmare. these challenges don’t even include the messy question of preservating an object so that it is usable in a century or five. while we probably will be able to read word and excel files for the foreseeable future, there are already countless files created with nowdefunct pc applications of the 1980s and 1990s; many are stored on all kinds of obsolete media and today are skating on the edge of inaccessibility. already we are seeing concern expressed at institutions with significant digital library and digitization commitments that curating, migrating, and ensuring the integrity and usability of growing petabytes of content over centuries may be unsustainable in both dollars and staff.3 can we even imagine the possible maintenance burden for our descendants, say, 250 or 500 years from now? in 2006, alexander stille observed that “one of the great ironies of the information age is that, while the late twentieth century will undoubtedly have recorded more data than any other period in history, it will also almost certainly have lost more information than any previous era.”4 how are we to deal with this? can we meaningfully plan for the preservation of digital content over centuries given our poor track record over just the past few decades? perhaps we’re thinking too big when we speak of “forever.” maybe we need to begin by conceptualizing and implementing on a more manageable scale. or, to adopt a phrase that seemed to become

program for discovery mini-conference that had just been held at unlv. the presentations, originally cast as poster sessions, suggested a diverse and fascinating collection of insights deserving of wider attention. i suggested to judith that she and her colleagues had the makings of a great ital theme issue, and i’m pleased that they accepted my invitation to rework the presentations into a form suitable for publication here. i hope that you will find the results of their work interesting—i certainly do. they’ve done a superb job! bravo to judith and the presenters at the unlv discovery

on order—although a considerable chunk of that 84 is going to replace storage that’s going out of warranty/maintenance and is more cost effective to replace (apple xraids, for instance). in the end, though we’ll net out with 100tb or thereabouts by the end of next year. a great deal of this space is going to digitization projects—no surprise there. we have over 20tb now in our “digital archive,” storage i consider dim, if not dark. we need a heck of a lot of space for staging backups, givien [sic] how much we write to tape in a 24-hour period. individual staff aren’t abusing our lack of quotas—it’s really almost all legitimate, project-driven work that’s eating us up. what’s scarier is that we’re now talking seriously about moving from project-driven work to programmatic work: the latest large photographic archive we acquired is being scanned as part of the acquisition/processing workflow. we’re looking at ways to prioritize the scanning of our manuscript collections. donors increasingly expect to see their gifts online. and we’re not even yet supporting an “institutional repository.” will owen, “0 to 60 in three years: mass storage management,” online posting, dec. 8,

division. each letter’s copyright is held by its authors and is published under a creative commons cc-by-nc-4.0 license. dear editors, at the risk of coming across as a defensive cataloger afraid of losing my job, i am writing to respond to the article published in ital vol. 43, no. 3 by richard brzustowicz, “from chatgpt to catgpt: the implications of artificial intelligence on library cataloging.” to mr. brzustowicz’s credit, he does not advocate that chatgpt can or should replace human catalogers wholesale, or that chatgpt should be used for cataloging without human intervention. he also correctly identifies potential issues of bias inherent in relying on artificial intelligence (ai) for subject description. the potential promises and pitfalls of chatgpt and other ai technologies is something that catalogers should be paying attention to, and i thank mr. brzustowicz for sparking conversation. nevertheless, there was no indication given that mr. brzustowicz (self-identified as an instruction and outreach librarian) has adequate knowledge and credentials to evaluate chatgpt-generated marc records, or their possible implications for re-engineering cataloging work. he does not provide any information as to his cataloging background or training (if any), nor gives any indication as to whether he discussed or shared his experiment with catalogers at his institution or within his professional circle. if he had, many of the errors and misinterpretations of his data and outcomes may have been mitigated. brzustowicz shows his bias in the second sentence of his introduction: “unfortunately (emphasis added), this crucial process [i.e., cataloging] can be both labor-intensive and time-consuming, often requiring significant resources.” the characterization of the labor required for a crucial library task as “unfortunate” is one that catalogers have heard from library administrators for decades, and while i don’t think the slight was intentional, it adds ammunition to the argument that cataloging is too expensive and should be made more “efficient” (never mind the many efficiencies already in place in many libraries, including cooperative cataloging, shelf-ready, and heavy use of macros, batch processing, vendor-supplied records, and scripting technologies). close examination of the sample records brzustowicz provides shows that while chatgpt appears to be able to create basic descriptive metadata comparable to that found in oclc worldcat for many types of materials, it also seems to be bringing in data from other records that is inaccurate and/or inappropriate. all of the chatgpt derived records contain 040 fields identifying record creation or editing by different institutions, and two of the records include an oclc control number in marc field 035. in both cases, the oclc record number is for a completely unrelated resource, so it appears that chatgpt is pulling them in at random. there is no way to know which records chatgpt pulled the 040 data from, but in any event it should reflect brzustowicz’s institution rather than dlc (the library of congress) or other institutions. also, while brzustowicz cites the knopf 1996 edition of interview with the vampire, and its oclc record is the one used for comparison, his chatgpt-generated record indicates a different publisher and pagination. the fact that chatgpt “copy cataloged” the wrong edition seems to have escaped brzustowicz’s notice. information technology and libraries december 2023 letter to the editors 2 dezelar-tiedman the chatgpt record for the german edition of pedagogy of the oppressed, in addition to the erroneous 040 and 035 fields previously mentioned, also includes an 042 field indicating it is a pcc (program for cooperative cataloging) record. the last time i checked, chatgpt had not yet become a member of the bibco program, so incorrectly labeling an ai-generated record as such is highly problematic, as many libraries rely on the pcc coding to identify good quality records that can be imported without editing or significant review. as brzustowicz indicates, catalogers interested in using chatgpt to assist in cataloging work should do so with a critical eye. it could potentially be used as a starting point to generate a basic description but would require catalogers to closely examine the record to identify incorrect coding, check name headings against the authority file, and assess the suggested subject headings for accuracy and bias. with the examples given in brzustowicz’s article, chatgpt seems to improperly introduce coding and fields to its records that it doesn’t understand. the need to review this coding, and delete it from the record, would actually make the cataloging process less efficient. part of the catalogers’ job to train chatgpt might be to train it which fields to include and which to ignore. brzustowicz’s discussion section quickly indicates his misunderstanding of typical cataloging work. he states: “the ability to accurately create descriptive records using chatgpt could significantly reduce the time and resources required for copy cataloging: this could free up library workers to focus on other important tasks…”. first, the implication here is again that cataloging takes too much time and is less important than other library functions like collection development and user services. and brzustowicz seems unaware that significant reduction of time and staffing for copy cataloging has already been happening for decades. copy cataloging is defined as downloading an existing catalog record to a local catalog database, so why would we need chatgpt to generate another (imperfect) record if one already exists in worldcat or another source? copy cataloging is generally not the part of cataloging that is time consuming, especially since many libraries now batch load large portions of their records and use shelf-ready services, so that the majority of materials arrive at the library ready to be checked in and placed on the shelf, with no item-level cataloging needed. even for smaller institutions (such as brzustowicz’s) that may not have the budget to employ some of these innovations, other low-cost methods exist (including using z39.50) to acquire copy records accurately and efficiently. it’s the original and specialized cataloging that is time consuming. while chatgpt has some potential to be used as a starting point in generating a description where no record exists, or to assist with the assignment of subject terms, it is just one of many tools that a cataloger might employ, and it still needs to learn a lot before it can be of substantial help in making the original cataloging process more efficient. assuming that this article was submitted for peer review, i suggest that the editors take a more critical eye on articles where the author’s credentials do not seem to match his subject. had this submission been reviewed by an experienced cataloger, the inaccuracies regarding contemporary cataloging workflows, and his interpretation of his results, could have been corrected prior to publication. sincerely, christine dezelar-tiedman cataloging policies and practices librarian university of minnesota libraries dezel002@umn.edu mailto:dezel002@umn.edu service barometers: using lending kiosks to locate patrons public libraries leading the way service barometers using lending kiosks to locate patrons william yarbrough information technology and libraries | june 2021 https://doi.org/10.6017/ital.v40i2.13499 public libraries have been using lending kiosks for close to ten years now. typically, kiosks are used as a sort of satellite collection, delivering library services directly to the community. often, they target people with limited mobility or who lack reliable transportation. reaching these underserved populations helps expand a library’s service area and users, which can factor in to state aid. but when amanda jackson first took over as director for the chesapeake public library, back in 2018, one of her first ideas involved using lending kiosks in a way that’s slightly unconventional. chesapeake is the second largest city in the commonwealth of virginia, measuring at 350 square miles. while considered suburban, the city is also plenty rural, with large areas of farmland, forest, swamps, and river. one of those areas is southern chesapeake. spanning roughly 130 square miles, southern chesapeake stretches all the way down to the border with north carolina. the closest library, however, is located on the northern end of the city, all the way up in great bridge. this library, which houses over 289,000 items (not to mention a law library and history room), is the largest in the city. more than 500,000 people visit it annually. still, for many of the 19,586 res idents in southern chesapeake, it’s a bit of a hike. for this size population, breaking ground on a new library branch would be warranted. especially since that population is growing. from 2018 to 2019, southern chesapeake saw its population increase by 1.62%, good for second highest among the city’s nine boroughs. but even a small library, of, say, 12,000 square feet, would cost $3 million—and that’s being conservative. justifying that big of an expense, both to the city council and local taxpayers, requires proving a return on investment. “building a new library brings a lot of excitement and energy into the community,” jackson says. “but first, to support that decision, we need to better understand what south chesapeake needs from the library.” the first person jackson turned to was maiko medina, who heads up cpl’s it division. like jackson, medina has worked in libraries for close to 20 years, first as frontline staff before transitioning to it. while with the neighboring virginia beach public library system, he helped install a variety of new systems, including self-checkout kiosks. together, medina and jackson came up with a plan, that uses lending kiosks as a type of service barometer. cpl would install kiosks all around south chesapeake, at city parks, community william yarbrough (wyarbrou@infopeake.org) is administrative assistant, chesapeake public library. © 2021. mailto:wyarbrou@infopeake.org information technology and libraries june 2021 service barometers | yarbrough 2 centers, police and fire stations, and local businesses. each kiosk would provide a sel ection of new and popular items from the library’s catalogue, from which patrons could check out on the spot. “by studying how the kiosks are used, we’ll get a better idea for where our patrons are,” medina says. “it’ll also tell us what they’re interested in.” this plan was submitted as a capital project. at a proposed $113,000, the project would fund one initial lending kiosk, along with an accompanying holds locker. chesapeake city council approved this project for fiscal year 2020. installation of the first kiosk in southern chesapeake was then scheduled for 2021. however, when the covid-19 pandemic hit, jackson, medina and the rest of the team at cpl recognized the need to speed the plan into action. “we kept hearing about how kids were struggling with virtual learning,” jackson says, “especially those in our underserved communities.” one of those communities is south norfolk. among the neighborhood’s 22,851 residents, 59.2% identify as black. 31% are 19 or younger. of those children, 39% are enrolled at a title i school. as schools were forced to move learning online, many of these students fell behind, whether because they lacked reliable internet, access to a home computer, or both. to meet this need, the neighboring dr. clarence v. cuffee library was transformed into an outreach and innovation center. along with a business center, maker spaces, stem walls, and a rotating art gallery, the new-and-improved cuffee library came with a student learning center. through this service, students can schedule one-on-one tutoring appointments with library staff and local college students, either virtual or in-person. of course, adding these new services required moving other things around. books, dvds, and other materials were redistributed to other libraries across the system. this may seem like an odd decision (after all, what’s a library without books?). but patrons weren’t using this library for materials; in fact, the number of items checked out from the collection (17,922) was significantly lower than any of the other six branches. still, the library didn’t want to abandon those patrons who rely on cuffee for more traditional services. especially since many were likely stuck at home during the pandemic. to meet this need, last october, shortly after the newly renovated dr. clarence v. cuffee outreach and innovation center opened, rather than wait until 2021, the library secured additional funding, through the cares act, to install a lending kiosk right outside the center’s main entrance. with this kiosk—a lendit 200 (courtesy of d-tech international)—patrons can check out from a rotating list of 200 items. they can also get any other item in the library’ collection by using the holdit locker (also from d-tech). both services are free and are available 24 hours a day, 7 days a week. so far, since last december, 136 items have been checked out through the cuffee lendit kiosk. another 304 have been checked out via the holds locker. among those check-outs, most popular are adult nonfiction dvds (33%) and adult fiction books (20%). as a result, more of these items will be rotated into the kiosk’s collection. not only that, but next month, the library will break information technology and libraries june 2021 service barometers | yarbrough 3 ground on another, bigger lending kiosk. located at fire station 7, this kiosk will be the first lendit 500 installed in south chesapeake. “the lending kiosk has really helped us continue to serve our patrons during all the changes brought on over the past 18 months,” say both jackson and medina. “now that things are starting to move ahead a little, we’re excited for how this technology will help us reach more of chesapeake.” over the next couple of years, chesapeake public library will use these lending kiosks to learn more about what the growing number of people in south chesapeake need from the library. maybe that’s more kiosks, a small storefront or even a full-sized, brick-and-mortar building. either way, new and innovative technologies like the lending kiosks will lead the way, helping cpl deliver services further into the community. 108 information technology and libraries | june 2006 tutorial writing your first scholarly article: a guide for budding authors in librarianship scott nicholson this series of questions and answers is designed to help you take the first steps toward the successful production of a scholarly article in librarianship. you may find yourself in a library position that requires writing or you may have just decided that you are ready to share your findings, experiences, and knowledge with the current and future generations of librarians. while following the guidelines listed here will not guarantee that you will be successful, these steps will take you closer to discovering the thrill of seeing your name in print and making a difference in the field. what should i write about? perhaps you already have an idea based upon your experiences and expertise, or perhaps you aren’t sure which of those ideas you should write about. the best way to start writing is to read other articles! many scholarly articles end with a future research section that outlines other projects and questions that the article suggests. it is useful to contact the author of a piece that holds a future research seed to ensure that the author has not already taken on that challenge. sometimes, the original author may be interested in collaborating with you to explore that next question. how do i start? scholarship is an iterative process, in that works that you produce are bricks in an ever-rising wall. your brick will build upon the works of others and, once published, others will build upon your work. because of this, it is essential to begin with a review of related literature. search in bibliographic and citation databases as well as web search tools to see if others have done similar projects to your own. the advantage of finding related literature is that you can learn from the mistakes of others and avoid duplicating works (unless your plan is to replicate the work of others). starting with the work of others allows you to place your brick on the wall. if you do not explicitly discuss how your scholarship relates to the scholarship of others, only those having familiarity with the literature will be able to understand how your work fits in with that of previous authors. in addition, it’s easier to build upon your work if those who read it have a better idea of the scholarly landscape in which your work lives. as you go out and discover literature, it is crucial to keep citation information about each item. much of what you will cite will be book chapters or articles in journals, and you will save yourself time and trouble later if you make a printed copy of source items and record bibliographic information on that copy. recording the title of the work, the full names (including middle initials) of authors and editors, page range, volume, issue, date, publisher and place of publication, url and date accessed, and any other bibliographic information at the time of collection will save you headaches later when you have to create your references list. as different journals have different citation requirements, having all of this information allows you the flexibility of adapting to different styles. one type of scholarship produced by libraries is the “how our library did something well” article. while a case study of your library can be an appropriate area of discussion, it is critical to position these pieces within the scholarship of the field. this allows readers to better understand how applicable your findings are to their own libraries. the concept illustrates the difference between the practice of librarianship and library science. library science is the study of librarianship and includes the generalization of library practice in one setting to other settings. before starting your writing, talk about your idea with your colleagues, which will help you refine your ideas. it will also generate some excitement and publicity about your work, which can help inspire you to continue in the writing process. colleagues can help you consider different places where similar works may already exist and might even open your eyes to similar work in another discipline. you may find a colleague who wants to coauthor the piece with you, which can make the project easier to complete and richer through the collaborative process. another important early step is to consider the journals you would like to be published in. many times, it can be fruitful to publish in the journal that has published works that are in your literature review. considering the journal at this point will allow you to correctly focus the scope, length, and style of your article to the requirements of your desired journal. your article should match the length and tone of other articles in that journal. most journals provide instructions to authors in each issue or on the web; the information page for ital authors is at www.ala.org/ala/ lita/litapublications/ital/information authors.htm. how can i find funding for my research? some projects can’t be easily done in your spare time and require resources for surveys, statistical analysis, travel, or other research costs. you will find that successful requests for funding scott nicholson (srnichol@syr.edu) is an assistant professor in the school of information studies, syracuse university, new york. writing your first scholarly article | nicholson 109 start with a literature review and a research plan. developing these before requesting funding will make your request for funding much stronger, as you will be able to demonstrate how your work will sit within a larger context of scholarship. you will need to develop a budget for your funding request. this budget will come together more easily if you have planned out your research. it may be useful or even required for you to develop a set of outcomes for your project and how you will be assessing those outcomes (find more information on outcome-based evaluation through the imls web site at www.imls.gov/grants/current/ crnt_obe.htm). developing this plan will give you a more concrete idea of what resources you will need and when, as well as how you can use the results of your work. resources for research may come from the inside, such as the library or the parent organization of the library, or from an external source, such as a granting body or a corporate donor. in choosing an organization for selection, you should consider who would most benefit from the research, as the request for funding should focus on the benefit to the granting body. many libraries and schools do have small pots of money available for research that will benefit that institution and that, many times, go untapped due to a lack of interest. granting organizations put out formal calls for grant proposals. these can result in a grant that would carry some prestige but would require a detailed formal application that can take months of writing and waiting. another approach is to work with a corporate or nonprofit organization that gives grants. if your organization has a development office, this office may be able to help connect you with a potential supporter of your work. how do i actually do the research? just as the most critical part of a dissertation is the proposal, a good research plan will make your research process run smoothly. before you start the research, write the literature review and the research plan as part of an article. it can be useful to create tables and charts with dummy data that will show how you plan to present results. doing this allows you to notice gaps in your data-collection plan well before you start that process. in many research projects, you only have a single chance to collect data; therefore, it’s important to plan out the process before you begin. how do i start writing the paper? the best way to start the writing process is to just write. don’t worry about coming up with a title; the title will develop as the work develops. you can skip over the abstract and introduction; these can be much easier to write after the main body of the article is complete. if you’ve followed the advice in this paper, then you’ve already written a literature review and perhaps a research plan; these make a good starting point for your article. one way to develop the body of the article is to develop an outline of headings and subheadings. starting with this type of outline forces you to think through your entire article and can help you identify holes in your preparation. once you have the outline completed, you can then fill in the outline by adding text to the headings and subheadings. this approach will keep your thinking organized in a way typically used in scholarly writing. scholarly writing is different than creative writing. many librarians with a humanities background face some challenges in transitioning to a different writing style. scholarly writing is terse; strunk and white’s the elements of style (2000) focuses on succinct writing and can help you refresh your writing skills.1 if you are having difficulty finding the time to write, it can be useful to set a small quota of writing that you will do every day. a quota such as four paragraphs a day is a reasonable amount to fit into even a busy day, but it will result in the completion of your first draft in only a few weeks. i’m finished with my first complete draft! now what? while you will be excited with the completion of the draft, it’s not appropriate to send that off to a journal just yet. take a few days off and let your mind settle from the writing, then go back and reread your article carefully. examine each sentence for a subject and a verb, and remove unneeded words, phrases, sentences, paragraphs, or even pages. try to tighten and clean your writing by replacing figures of speech with statements that actually say what you mean in that situation and removing unneeded references to firstand second-person pronouns. working through the entire article in this way greatly improves your writing and reduces the review and editing time needed for the article. after this, have several colleagues read your work. some of these might be people with whom you shared your original ideas, and others may be new to the concepts. it can be useful to have members of different departments and with different backgrounds read the piece. ask them if they can read your work by a specific date, as this type of review work is easy to put off when work gets busy. these colleagues may be people who work in your institution or may be people you have met online. if you know nobody who would be appropriate, consider putting out a request for assistance on a library discussion list focused on your research topic. dealing with the comments from others requires you to set aside your 110 information technology and libraries | june 2006 defenses. you did spend a lot of time on this work and it can be easy to slip into a defensive mode. attempt to read their comments from an objective viewpoint. remember—these people are spending their time to help you, and a comment you disagree with at first blush may make more sense if you consider the question “why would someone say this about my work?” putting yourself into the reader’s shoes can aid you in the creation of a piece that speaks to many audiences. what goes on when i submit my work? at this point, your readers have looked at the piece, and you have made corrections on it. now you’re ready to submit your work. follow the directions of the target journal, including length, citation format, and method of submission. if submission is made by e-mail, it would be appropriate to send a follow-up e-mail a few days after submission to ensure the work was received; it can be very frustrating to realize, after a month of waiting, that the editor never got the work. once you have submitted your work, the editor will briefly review it to ensure it is an appropriate submission for the journal. if it is appropriate, then the editor will pass the article on to one or more reviewers; if not, you will receive a note fairly quickly letting you know that you should pick another journal. if the reviewing process is “blind,” then you will not know who your reviewers are, but they may know your identity. if the process is “double-blind,” neither reviewer nor author will know the identity of the other. the reviewers will read the article and then submit comments and a recommendation to the editor. the editor will collect comments from all of the reviewers and put them together, and send those comments to you. this will always take longer than you would prefer; in reality, it will usually take two to six months, depending upon the journal. after a few months, it would be appropriate for you to contact the editor and ask about the progress on the article and when you should expect comments. do not expect to have your article accepted on the first pass. the common responses are: ■ reject. at this point, you can read the comments provided, make changes, and submit it to another journal. ■ revise and resubmit. the journal is not making a commitment to you, but they are willing to take another look if you are willing to make changes. this is a common response for first submissions. ■ accept with major changes. the journal is interested in publishing the article, but it will require reworking. ■ accept with minor changes. you will be presented with a series of small changes. some of these might be required and others might be your choice. ■ accept. the article is through the reviewing process and is on to the next stage. this is an iterative process. you will most likely go through several cycles of this before your article is accepted, and staying dedicated to the process is key to its success. it can be disheartening to have made three rounds of changes only to face another round of small changes. ideally, each set of requested changes should be smaller (and take less time) until you reach the acceptance level. do not submit your work to multiple journals at the same time. if you choose to withdraw your work from one journal and submit it to another, let the editor know that you are doing this (assuming they have not rejected your work). my article has been accepted. when will it come out? once your article is accepted, it will be sent into a copyediting process. the copy editor will contact you with more questions that focus more on writing and citation flaws than on content. after making more corrections, you will receive a proof to review (usually with a very tight deadline). this proof will be what comes out in the journal, so check important things like your name, institutions, and contact information carefully. the journal will usually come out several months after you see this final proof. the process from acceptance to publication can take from six months to two years (or more), depending on how much of a publication queue the journal has. the editor should be able to give you an estimate as to when the article will come out after full acceptance. can i put a copy of my article online? it depends upon the copyright agreement that you sign. many publishers will allow you to put a copy of your article on a local or institutional web site with an appropriate citation. some allow you to put up a preprint, which would be the version after copyediting but not the final proof version. if the copyright agreement doesn’t say anything about this, then ask the editor of the journal about the policy of authors mounting their own articles on a web site. conclusion writing an article and getting it published is akin to having a child. your child will have a life of its own, and others may notice this new piece of knowledge and build upon it to improve their own library services writing your first scholarly article | nicholson 111 or even make their own works. it is a way to make a difference that goes far beyond the walls of your own library, to extend your professional network, and to engage other scholars in the continued development of the knowledge base of our field. reference 1. w. strunk jr. and e. b. white, the elements of style (boston: allyn &

outlines freely available screen capturing tools, covering their benefits and drawbacks as well as their potential applications. in discussing these tools, the author illustrates how they can be used to build pathfinding tutorials for users and how these tutorials can be shared with users. the author notes that the availability of these screen capturing tools at no cost, coupled with their ease of use, provides ample opportunity for low-stakes experimentation from library staff in building dynamic pathfinders to promote the discovery of library resources. o ne of the goals related to discovery in the university of nevada las vegas (unlv) libraries’ strategic plan is to “expand user awareness of library resources, services and staff expertise through promotion and technology.”1 screencasting videos and screenshots can be used effectively to show users how to access materials using finding tools in a systematic, step-by-step way. screencasting and screen capturing tools are becoming more intuitive to learn and use and can be downloaded for free. as such, these tools are becoming an efficient and effective method for building pathfinders for users. one such tool is jing (http://www.jingproject.com), freeware that is easy to download and use. jing allows for short screencasts of five minutes or less to be created and uploaded to a remote server on screencast.com. once a jing screencast is uploaded, screencast.com provides a url for the screencast that can be shared via e-mail or instant message or on a webpage. another function of jing is recording screenshots, which can be annotated and shared by url or pasted into documents or presentations. jing serves as an effective tool for enabling librarians working with students via chat or instant messaging to quickly create screenshots and videos that visually demonstrate to students how to get the information they need. jing stores the screenshots and videos on its server, which allows those files to be reused in subject or course guides and in course management systems, course syllabi, and library instructional handouts. moreover, jing’s files storage provides an opportunity for librarians to incorporate tutorials into a variety of spaces where patrons may need them in such a manner that does not require internal library server space or work from internal library web specialists. trailfire (http://www.trailfire.com) is another screencapturing tool that can be utilized in the same manner. trailfire allows users to create a trail of webpage screenshots that can be annotated with notes and shared with others via a url. such trails can provide users with a step-by-step slideshow outlining how to obtain specific resources. when a trail is created with trailfire, a url is provided to share. like jing, trailfire is free to download and easy to learn and use. wink (http://debugmode.com/wink) was originally created for producing software tutorials, which makes it well suited for creating tutorials about how to use databases. although wink is much less sophisticated than expensive software packages, it can capture screenshots, add explanation boxes, buttons, titles, and voice to your tutorials. screenshots are captured automatically as you use your computer on the basis of mouse and keyboard input. wink files can be converted into very compressed flash presentations and a wide range of other file types, such as pdf, but do not support avi files. as such, wink tutorials converted to flash have a fluid movie feel similar to jing screencasts, but wink tutorials also can be converted to more static formats like pdf, which provides added flexibility. slideshare (http://www.slideshare.net) allows for the conversion of uploaded powerpoint, openoffice, or pdf files into online flash movies. an option to sync audio to the slides is available, and widgets can be created to embed slideshows onto websites, blogs, subject guides, or even social networking sites. any of these tools can be utilized for just-in-time virtual reference questions in addition to the common use of just-in-case instructional tutorials. such just-in-time screen capturing and screencasting offer a viable solution for providing more equitable service and teachable moments within virtual reference applications. these tools allow library staff to answer patron questions via e-mail and chat reference in a manner that allows patrons to see processes for obtaining information sources. demonstrations that are typically provided in face-toface reference interactions and classroom instruction sessions can be provided to patrons virtually. the efficiency of this practice is that it is simpler and faster to capture and share a screencast tutorial when answering virtual reference questions than to explain complex processes in written form. additionally, the fact that these tools are freely available and easy to use provides library staff the opportunity to pursue low-stakes experimentation with screen capturing and screencasting. the primary drawback to these freely available tools is that none of them provides a screencast that allows for both voice and text annotations, unlike commercial products such as camtasia and captivate. however, tutorials rendered with these freely available tools can be repurposed into a tutorial within commercial applications like camtasia studio (http://www.techsmith.com/camtasia .asp) and adobe captivate (http://www.adobe.com/ products/captivate/). patrick griffis (patrick.griffis@unlv.edu) is business librarian, university of nevada las vegas libraries. 190 information technology and libraries | december 2009 as previously mentioned, these easy-to-use tools can allow screencast videos and screenshots to be integrated into a variety of online spaces. a particularly effective type of online space for potential integration of such screencast videos and screenshots are library “how do i find . . .” research help guides. many of these “how do i find . . .” research help guides serve as pathfinders for patrons, outlining processes for obtaining information sources. currently, many of these pathfinders are in text form, and experimentation with the tools outlined in this article can empower library staff to enhance their own pathfinders with screencast videos and screenshot tutorials. reference 1. “unlv

washington, d. c. monday, january 29, 1973 the meeting was called to order by president ralph shoffner at 8:10a.m. the following were present: board-ralph m. shoffner (chairman ) , richard s. angell, don s. culbertson (!sad executive secretary), paul j. fasana, donald p. hammer, susan k. martin, and bemiece coulter, secretary, isad. committee chairman-stephen r. salmon. guestscharles stevens and david weisbrod. report of national commission on library and information science. mr. charles stevens, executive director of the national commission on library and information science, discussed the commission's priorities and objectives for planning libmry and information services for the nation. the commission has identified six areas of activity in which to conduct investigations in relation to its charge which is to study " ... library and information services adequate to meet the needs of the people of the united states." these six: areas are: ( 1) understanding information needs of the users; ( 2) adequacies and deficiencies of current library and information services; ( 3) pattems of organization; ( 4) legal and financial restrictions on libraries; ( 5) technology in library and information systems; and ( 6) human resources. report to ala planning committee. the report to the ala planning committee on !sad's long range plans was deferred until after the !sad objectives committee report is received in june. objectives committee interim report. mr. stephen salmon, chairman, provided an interim report of the committee. the committee will recommend that the division continue to exist and will list its proposed objectives, which may differ from the original objectives. at the request of louise giles, chairman of the information technology discussion group, special attention will be given to that group's interests in formulating the statement of objectives. membership survey committee. mr. shoffner relayed ms. pope's report that the membership survey will cost $700.00, which is not available in the current budget. mr. culbertson said that the cost could be decreased by surveying a sample of 1,000 members. the decision was to highlights of minutes 57 request the full amount for the survey, to be performed in the coming fiscal year. asidic representative. mr. peter t. watson, through correspondence with mr. shoffner, reported that asidic is interested in liaison with ala, and was concerned with the possibility of accomplishing this through isad. mr. culbertson reported that asidic could become an affiliate of ala for a $40.00 fee, but that isad could recommend a formal liaison, especially if isad and asidic had similar interests. motion. it was moved by paul fasana that this matter of asidic liaison with ala be passed on to the executive director, mr. robert wedgeworth, and that the president of isad write and inform him of such. seconded by richard angell. carried. policy statement on privacy of data processing records. mr. culbertson had been approached about !sad's making a statement on broad issues of data processing, including privacy. a need has been made known by the ala washington office for having such a statement on which to base their stand in certain hearings. mr. hammer felt it very appropriate that the association (ala) take a position on it. mr. weisbrod mentioned that !sad could be involved because of the vulnerability of machine-readable files due to the large quantity of data processed. motion. it was moved by paul fasana that the isad board recommend to the ala council that it (ala) develop some policy expressing its membership's attitude toward the privacy of machine-readable data. seconded by donald hammer. carried. ]ola editor. mr. shoffner reported, concerning the appointment of an editor, that two contacts were outstanding and he would report to the board on wednesday. mr. culbertson has been serving as temporary editor. mr. fasana noted that the schedule for 1972 was for four issues, but only one had appeared. he asked what plans there were to catch up or cancel. mr. culbertson said that legally isad could not cancel any issues, and that a statement had been written for the "memo to members" section of american libraries. he also mentioned the previous board action to have ]ola te chnical communications become a part of the 1973 volume. wednesday, january 31, 1973 mr. shoffner called the meeting to order at 10:00 a.m. those present were: board-ralph m. shoffner (chairman), richards. angell, dons. culbertson (!sad executive secretary), paul j. fasana, donald p. hammer, susan k. martin, and berniece coulter, secretary, isad. committee chairmen-brigitte kenney, ronald miller, and velma veneziano. guest-peter watson. conference planning committee report. mrs. susan 58 journal of library automation vol. 6/ 1 march 1973 martin, chairman, reported that the 1972 seminar on telecommunications had been successful, and the april seminar with the national microfilm association in detroit was proceeding as scheduled. the seminar on the national libraries, originally scheduled for january, and the seminar on netm works which was to be in march had both been postponed until the next fiscal year. planning of the las vegas preconference program is continuing smoothly; the institute is to be concerned with a review of the state-of-the-art of library automation. it will update the !sad preconference institute of 1967. isad / led education committee report. a written report was submitted. (see exhibit 1.) rtsd / isad / rasd representation in machine-readable form of bibliographic information committee report. chairman vehna veneziano reported that as a result of a ]ola technical communications announcement that the committee meeting was open and that there would be discussion of the controversial international standard bibliographic description ( isbd), 2()0-300 persons attended the committee meeting. the committee felt that changes such as isbd in the marc records by the library of congress should take into account the users of the marc distribution service. committee action on the isbd was delayed until the isbd for serials proposal was further along. it was stated that the isbd for serials should be as consistent as possible with the isbd for monographs. the committee suggested that each division publish these standards in its journal. motion. it was moved by paul fasana that the !sad board suggest to the jola editorial board that discussion drafts of standards be published in the ] ournal of library automation. seconded by donald hammer. carried. mrs. veneziano pointed out that a resolution was passed concerning the formation of an ad hoc task force for a period of two years. the task force would work with emerging standards relating to character sets: greek and cyrillic alphabets; mathematical and logical symbols; and control characters relating to communications. three persons were suggested for the task force: charles payne of the university of chicago, david weisbrod of yale, and michael malinconico of the new york public library in addition to lucia rather and henriette avram of the library of congress. the task force would report back to the board through the committee. motion. it was moved by paul fasana that !sad consider the creation of a task force to work with emerging standards relating to character sets and the insertion of a fund request in the isad budget for $1,060 ( $700 for 2 trips for 3 persons and $360 per diem for 3 persons for 2 days for each of 2 trips). seconded by donald hammer. carried. highlights of minutes 59 the committee wished to go on record that since rtsd had recently formed a committee on computer filing that computer filing rules was a function of the interdivisional committee on representation in machinereadable form of bibliographic information. the subject of library codes was discussed. bowker was assigning numeric codes to libraries, book publishers, and book dealers. the committee is concerned about standards and does not wish to see the creation of systems of incompatible codes. telecommunications committee report. brigitte kenney, chairman, submitted a written 18-month report of the committee (exhibit 2). miss kenney announced that she was resigning as chairman of the committee and that no present member was available to assume the chairmanship. mr. hammer, as president-elect, was charged with appointing the next chairman. the function statement of the telecommunications committee has been grouped into four areas: ( 1) communication to members; ( 2) training; ( 3) legislative matters; and ( 4) research. she pointed out that both ]ola technical communications and american libraries had said in writing that they would accept articles on telecommunications, particularly cable tv, and had accepted none. also, she ltad attempted for a year and a half to assemble an information packet at ala headquarters, but did not know the status of the project. headquarters had requested guidelines on cable policy from the committee; she stated that they had not succeeded in completing this task. no guidelines had been provided. mter !sad and ala sources did not respond to a request to publish a cable newsletter, the american society for information science was approached. the asis council approved this the previous friday and she had obtained seed money from the markle foundation. miss kenney referred to the resolution introduced that afternoon in council that an ad hoc ala committee be established to address itself exclusively to cable matters and be representative of all units of ala, and that it take on very specific tasks with clearly delineated time limits. she further stated that she had not felt that !sad had given adequate support to the isad telecommunications committee's activities, and thought that the board would have to decide if this was an appropriate committee for !sad. if so, was the function statement too broad? should it be narrowed to just data transfer? miss kenney also suggested that the committee be expanded in size to include more people involved in telecommunications. in the discussion which followed it was indicated that it could take from two to three years to set up a committee in ala as an interdivisional committee. it was decided that a committee chairman should be found and that 60 journal of library automation vol. 6/1 march 1973 the board could then work with the chairman in the definition of the tasks to be performed. publishing of minutes. it was decided that the board of directors express to the editorial board their desire that the minutes of board meetings be published in the journal. seminar and institute topics committee report. ronald miller~ chairman, enumerated the following points of the committee's meeting: that ( 1) a long range plan for seminar programs be written to cover the period from july 1974 through june 1978; (2) part of the money from the institutes be budgeted to support a professional staff person at ala headquarters to handle the burden of the work; ( 3) policy be established concerning commercial groups using isad programs for a marketing channel, particularly products of use to libraries; ( 4) institutes or seminars be regionalized in the u.s. and canada; and ( 5) liaison efforts be utilized (a) within the network of ala, (b) through subcontractors, and (c) through continuing education programs of library schools or other institutes of higher education. in the discussion by the board it was agreed that a written document, both specific and general, be put before the isad membership concerning future seminar and institute topics in order to obtain reactions. ]ola editor appointed motion. it was moved by donald hammer that the board approve the appointment of susan k. martin as editor of the journal of library automation. seconded by paul fasana. carrjed. tribute to don culbertson. "the board commended don s. culbertson for long, energetic and useful service to isad." exhibit 1 january 23, 1973 !sad/led education committee report the isad/led education committee met sunday, january 28, at 9:30 a.m. in the garden restaurant of the shoreham hotel. present were members james liesener, robert kemper, gerald jahoda, edward heiliger, and (ex officio ) ralph shoffner. absent were ann painter and duane johnson. discussion focused on disc (developmental information science curriculum), what has been achieved by the disc contingent working under the aegis of asis, and how isad/ led could contribute to achieving the disc objective of producing transferable "modules" or packaged programs for information science teaching. it was decided that to reach this objective what would be required were: ( 1) an overall structure or frame of reference which could be used to coordinate modules developed by interested and dedicated individuals. (2) specifications for module construction. re 2lt was decided to await the completion of modules currently b eing developed by charles davis and david buttz and to examine these (at las vegas) as providing guidelines for module specifications. highughts of minutes 61 re l-it was suggested by ralph shoffner that a frame of reference might be achieved, with some dispatch, by drawing up a list of about 20 questions in the area of information science, which library schools might expect their graduating students to answer, each question being answerable in no more than an hour. the idea was that modules might be designed around these questions. also, it was seen that these questions might serve a useful purpose in organizing information science teaching in light of professional program evaluation and accreditation. the suggestion of "questions" was enthusiastically received and the following day gerald jahoda, edward heiliger and charles davis drew up a "sample" list of questions and outlined the following procedure: ( 1) the sample list of questions is sent to isad /led education committee members as well as to asis sig/eis and asis education committee members for recommendations in the way of additions, deletions and word revisions. by february 15, 1973.

(a first for librarians!) e. liaison was maintained with nonlibrary groups: publicable, of which the chairman is a member, the mitre symposium on cable, to which the chairman was invited, and, as a result of that meeting, the aspen workshop on cable in palo alto, which the chairman attended by invitation from douglass cater, together with eight other people, to decide on the direction this activity should take. at all three meetings the chairman attempted to represent the library viewpoint on cable. f. a las vegas program was to be planned, together \vith acrl and the av committee. plans did not materialize, and the committee is being approached by the soon-to-be-established srrt task force on cable to cosponsor a program on cable at las vegas. 2. training: 1. institute on cable television for librarians: held september 1720, 1972, and attended by over 100 librarians from thirty-four states, representing public and state libraries primarily, this was directed by the chairman, and funded by usoe. russell shank and frank norwood, consultants to the tc committee presented major talks. the entire institute was videotaped and the tapes are available. proceedings will be issued in march as a double issue of the drexel library quarterly. the institute was designed to provide a format and material (including videotaped presentations) to allow others to do their own institutes. 2. telecommunications seminar: conducted by russell shank, consultant to the tc committee, it presented an overview over various aspects of telecommunications. held in washington september 25-26, 1972, it, too, was attended by almost 100 ji. brarians from all types of libraries. the chairman and frank norwood, consultant, participated in the presentation of papers. 3. legislative matters: the committee expressed its concern to the ala legislation committee about the lack of sufficient personnel to keep abreast of legislative and regulatory matters affecting telecommunications. the chairman of the legi~lation committee responded by stating that the ala washington office had been trying to do their best, in the absence of funding for additional personnel, and would continue to do so. the committee attempts to follow legislative and regulatory developments in the telecommunications area, and works closely with the washington office in this activity, providing persons to testify, and supplying two of the four members of the subcommittee on copyright (shank and kenney) . the committee participated actively in the revision of the ala policy booklet, concerning itself with matters pertaining to networks and telecommunications. all recommendations were incorporated in the final draft of this document. 4. research: the telecommunications requirements study, long ago proposed, is dormant. shank and kenney are actively working on putting together a proposal to respond to a call for proposals from nsf in the area of telecommunications policy research. the committee will discuss the proposal during the midwinter meeting, 1973. respectfully submitted, brigitte kenney google us!

(at the time, we were able to get a validation token from our existing tech soup account, but koios currently recommends starting by registering a 501c3 friends organization or library foundation with tech soup whenever possible.) after creating our google for nonprofits account, we used the same account username to create a google ads account. finally, to work efficiently with koios,

we in turn review and approve). if you are taking the do-it-yourself approach, google has a step-by-step google ad grants activation guide and extensive help online. designing campaigns spending money well is hard work and that holds true with keyword search ads as well. there are some performance and ad quality requirements in the grant program that must be observed to retain your monthly allotment. understanding these guidelines and implementing campaigns that respect them, while working well enough to spend your grant allocation requires study and patience. again, we relied on koios to guide us. they helped us create campaigns and ad groups within those campaigns that were effective within the grant program. figure 1. example of minecraft title keyword landing page created by koios. information technology and libraries march 2020 google us! | knox and smiley 3 in august 2018, we started with campaigns for general branding awareness that included ads aimed at people actively searching for local libraries and our core services. these ads funnel users to our homepage and our online card signup. they are configured to display only to searchers who are geographically located in our service area. this campaign has been grown and perfected over 18 months into one of our most successful campaigns, garnering over 2,300 impressions and 650 clicks in january 2020, yet it spends just $450 of our grant funds. another consistent performer for us has been our digital media campaign with ads targeting users searching for ebooks and audiobooks. by june 2019 we had grown our grant spend to $1,500 a month using 27 different campaigns. the game changer for us has been working with koios to create campaigns based on an export of marc records from our catalog. we worked with koios to massage this data into a very simple pseudo-catalog of landing pages based on item titles. the landing page is very simple and seo friendly so that it ranks well in the split-second ad auction competition that determines whether your ad will be displayed. it has cover images, clear calls to action, loads fast, is mobile friendly and communicates the breadth of formats held by the library (see figure 1). clicking the item title or the borrow button sends users straight into our full catalog to get more information, request the item, or link to the digital version. figure 2. a

the ad and the resulting catalog page if the searcher clicks the borrow button. in google ads, koios created 14 catalog campaigns out of the roughly 250,000 titles we sent them. each campaign has keywords (single words and phrases from titles) derived from roughly 18,000 titles ranked by how frequently they are used in google search. again, these ads are limited geographically to our service area. figures 2 and 3 illustrate what a google searcher in ingham county, michigan, potentially encounters when searching for “dad jokes”. since their inception in september 2019, these catalog campaigns have been top performers for us, generating clickthrough rates of 8-15% and a couple thousand additional ad clicks monthly, the aggregation of a small number of clicks on any one ad from our “long tail” of titles. we are now spending over $5,000 of our grant funds and garnering nearly 23,000 impressions and 3,000 ad clicks monthly. results in general, we find that our google ads have succeeded in drawing additional new visitors to our web site. using our long-established google analytics implementation that measures visits to our website and catalog combined, we compared the third quarter of 2018, when we were ramping up our google ad grants campaigns, to the third quarter of 2019, after our catalog campaign was firmly established. the summary numbers are encouraging. the number of users is up 17%, and number of sessions is up 4%. within the overall rise in users, returning users are up 9%, but new users are up 25%. therefore, we are getting more of those coveted, elusive “non-library-users” to visit us online. when comparing the behavior of new and returning visitors, we also see that the overall increase in sessions was achieved despite the head wind of a 4% decline in returning visitor sessions. however, are the new visitors engaging? perhaps the most tangible measure of engagement for a public library catalog is placing holds. we have a google analytics conversion goal that measures those holds. the information technology and libraries march 2020 google us! | knox and smiley 5 rate of conversion on the hold goal among new visitors rose 7%, while dropping 13% among returning visitors. from other analysis, we know that our highly-engaged members are migrating to our mobile app and to digital formats, so the drop for returning users is explainable and the rise among new visitors is hopeful. we are working on ways to study more closely these new visitors so that we can discover and remove more barriers in the way of them becoming highly engaged members of their public library. future plans with the help of koios, new campaigns will be created to promote our blogs and podcasts. we will also link a campaign to our demco events database. finally, in partnership with koios, we will work with patron point to incorporate our automated email marketing system into google ad campaigns. we will add campaigns for pop-up ads that encourage library card signup through our online registration system. once someone signs up for a library card online, the system will trigger a welcome email that promotes some of our core services. this on-boarding set-up will also include an opportunity for the new cardholder to fill out a form to tailor content in future emails to their interests. through all these means, cadl leads the way in delivering the right service, at the right time, to the right person. getting started designing campaigns results future plans 222 information technology and libraries | december 2006 social engineering is the use of nontechnical means to gain unauthorized access to information or computer systems. while this method is recognized as a major security threat in the computer industry, little has been done to address it in the library field. this is of particular concern because libraries increasingly have access to databases of both proprietary and personal information. this tutorial is designed to increase the awareness of library staff in regard to the issue of social engineering. one morning the phone rings at the circulation desk; the assistant, joyce, answers. “seashore branch public library, how may we help you?” she asks, smiling. “my wife and i recently moved and i wanted to confirm that you had our current address,” a pleasant male voice responds. “could you give me your name please?” “the card is in my wife’s name, jennifer greene. we’ve been so busy with the move that she hasn’t had a chance to catch up with everything.” “okay, i have her information here. 123 main street, apartment 2b. is that correct?” “thank you so much, that’s it. do you have our new number or is it still 555-555-1234 in your records?” “let me see . . . no, i think we have your new number.” “could you read it back to me?” “sure . . . 555-555-6789, is that right?” “555-555-6789 . . . that’s right. thank you very much, you’ve been very helpful.’ “no problem, that’s what we’re here for.” <click> what just happened? what happened to joyce may have been exactly what it appeared to be—a conscientious spouse trying to make sure information was updated after a move. but what else could it have been—research for an identity theft, or a stalker trying to get personal information? we have no way of knowing. all reasons except for the first, innocent, reason are covered by the term social engineering. in the language of computer hackers, social engineering is a nontechnical hack. it is the use of trickery, persuasion, impersonation, emotional manipulation, and abuse of trust to gain information or computer-system access through the human interface. regardless of an institution’s commitment to computer security through technology, it is vulnerable to social engineering. recently, the institute of management and administration (ioma) reported social engineering as the number-one security threat for 2005. according to ioma, this method of security violation is on the rise due to continued improvements in technical protections against hackers.1 why and how does social engineering work? the first thing to keep in mind about social engineering is that it does work. kevin mitnick, possibly the best known hacker of recent decades, carried out most of his questionable activities through the medium of social engineering.2 he did not need to use his technical expertise because it was easier to just ask for the information he wanted. he discovered that people, when questioned appropriately, would give him the information he wanted. social engineering succeeds because most people work under the assumption that others are essentially honest. as a pure matter of probability, this is true; the vast majority of communications that we receive during the day are completely innocent in character. this fact allows the social engineer to be effective. by making seemingly innocuous requests for information, or making requests in a way that seems reasonable at the time, the social engineer can gather the information that he or she is looking for. methods of social engineering the arsenal of the social engineer is large and very well established. this is mainly because social engineering amounts to a variation on confidence trickery, an art that goes back as far as human history can recall. one might argue that homer’s iliad contains the first record of a social engineering attack in the form of the trojan horse. direct requests many social-engineering methods are complex and require significant planning. however, there is a simple and effective method that is often just as effective. the social engineer contacts his or her target and simply asks for the information. preying on trust and emotion social engineering is a method of gaining information through the persuasion of human sources, based on the abuse of trust and the manipulation of emotion. in his book, the art of deception, mitnick makes the argument that once a social engineer has established the trust of a contact, then all security is effectively voided and helping the hacker? library information, security, and social engineering samuel t. c. thompson samuel t. c. thompson (sthompson@ collier-lib.org), is a public service librarian at the collier county public library, naples, florida. helping the hacker? | thompson 223 the social engineer can gather whatever information is required. the most common method of targeting computer end-users is through the manipulation of gratitude. in these cases, a social engineer, usually impersonating a technician, contacts a user and states that there is something wrong on the victim’s end, and that the social engineer needs a few pieces of information to “help” the user. appreciative of the assistance, the victim provides the necessary information to the helpful caller or carries out the requested actions. predictably, no problem ever existed and the victim has now provided the social engineer either access to a computer system or with the information needed to gain that access. a counterpoint to the manipulation of gratitude is the manipulation of sympathy. this method is most often used on information providers such as help-desk personnel, technicians, and library staff members. in this scenario, a social engineer contacts a victim and claims to have either lost information, is out of contact with a normal source, or is simply ignorant of something that he or she should know. as anyone can empathize with this plea, the victim is often all too willing to provide the information sought by the social engineer. using these methods—taking advantage of the gratitude, sympathy, and empathy of their victims—social engineers are able to achieve their aims. impersonation because forming trust relationships with their victims is critical to a socialengineering attack, it is not surprising that social engineers often pretend to be someone or something that they are not. two of the major tools of impersonation are (1) speaking the language of the victim institution and (2) knowledge of personnel and policy. to allay suspicion, a social engineer needs to know and be able to use an institution’s terminology. being unable to do so would cause the victim to suspect, rather than trust, the social engineer. with a working knowledge of an organization’s particular vocabulary, a social engineer can phrase his or her request in terms that will not rouse alarm with the intended victim. the other major goal of a social engineer in preparing a successful impersonation is to develop a familiarity with the “lay of the land,” i.e., the specifics of and personnel within an organization. for instance, a social engineer needs to discover who has what authority within an organization so as to understand for whom he or she needs to claim to speak. research to establish trust in their victims, social engineers use research as a tool. this comes in two forms, background research and cumulative research. background research is the process by which a social engineer uses publicly available resources to learn what to ask for, how to ask for it, and whom to ask it of. while the intent and goal of this research differs from the techniques used by students, librarians, and other members of the population, the actual process is the same. cumulative research is the process by which a social engineer gathers the information that he or she needs to make more critical requests of their victims. the facts that a social engineer seeks through cumulative research may seem without value to the casual observer, but put together properly, they are anything but that. questions can include names of staff, internal phone numbers, procedures, or seemingly minor technical details about the library’s network (e.g., what operating system are you running?). late in the afternoon the phone at the reference desk rings. marcy, the librarian on duty answers, “reference desk.” “hi there, this is dave simpson calling from information services at the main branch. sorry about the echo, i’m working in the cabling closet at the moment, so i’m calling you on my cell phone.” “no problem, i can hear you fine. what can i do for you?” “thanks. a lot of the branches have been having network problems over the last few days. has everything been okay at the seashore branch reference desk?” “i think so.” “okay, that’s good. i’m running a test right now on the network and needed to find a terminal that was behaving itself. could you log off and let me know if any messages come up?” “no problem.” marcy logs off of the reference computer; nothing strange happens. “just the usual messages.” “good. now start logging back on. what user are you going in as? i mean which login name are you using?” “searef. okay, i’m logged on now.” “no strange messages?” “nothing.” “that’s great. look, our problem might be kids hacking into the system so i need you to change the password. do you know how to do that?” “i think so.” “well, let me walk you through it.” dave spends a couple of minutes walking marcy through changing the system password. the password is now changed to 5ear3f, a moderately secure password. “thanks, marcy. you’ve been a great help. we have your new password logged into the system. could you pass on the new password to the other reference personnel?” “sure.” “wonderful. just remember not to give the password out to anyone who doesn’t need it, and don’t write it down where anyone who shouldn’t have it can get at it. have a great day.” “you too.” <click> 224 information technology and libraries | december 2006 why are libraries vulnerable? libraries are vulnerable to social-engineering attacks for two major reasons: (1) ignorance and (2) institutional psychology. the first of these difficulties is the easiest to address. the ignorance of library professionals in this matter is easily explained—there is very little literature to date about the issue of social engineering directed at library personnel. what exists is usually mixed in larger articles on general security issues and receives little focus. this lack of concern about social engineering can also be seen in computer professional literature, where it is dwarfed by the volume of articles concerning technical security issues. this is a curious gap, considering the high rate of occurrence of this kind of attack. is it because many technical professionals are less comfortable with a social issue—that can only be solved through people—than with a technical security issue that can be solved through the development or implementation of proper software?3 unfortunately, not knowing about a method of security violation leaves one vulnerable to that method. it is incumbent on librarians, computer administrations, and security professionals to be aware of these issues. the second factor is harder to address but equally important. unlike almost any other profession, librarians are expected to fulfill their patrons’ informational needs without question or bias. this laudable goal makes librarians vulnerable to social-engineering attacks because the inquiries made by a social engineer about the information resources available at a library may be used for nefarious purposes. a reference interview over these issues may be very successful from the point of view of both parties involved, as the librarian fills the openended inquiries of the social engineer, and the social engineer receives much, if not all, of the information that he or she needs to violate the library’s internal information systems. why libraries can be targets at this point, it is relevant to ask why security violators would even bother with library computer networks. what do libraries have that is worth possibly committing a crime to get? personal information is probably the most tempting target in a library computer system. libraries possess databases of names, addresses, and other personal data about library cardholders. this information is valuable, and not all of it is easily available from public sources. as may be seen in the section of this article on techniques, such information could be used as an end unto itself or as a stepping stone to security violations in other systems. subscriptions to proprietary databases are quite expensive, as any acquisitions librarian will explain. given the high prices and limited licensing, a hacker may want to gain access to these information resources. this could be a casual hacker who wants to have access to a library-only resource from his or her home computer, or this may be a criminal who wishes to steal intellectual properties from a database provider. libraries often have broadband access designed for a large network (e.g., t1). as these lines are very expensive, few individuals can afford them. at the same time, it has been observed that these broadband lines have immense capabilities for downloading information from other networks. there are many reasons why a hacker would seek to illicitly use such a resource. for instance, a casual hacker may want to download a large number of bootlegged movie files, or a criminal may wish to download a corporate database. with access to a library’s high bandwith internet line, these actions can be carried out quickly and with a minimized chance of detection. libraries possess large numbers of computers due to their increasing automation. these computer resources can, if compromised, be used as anonymous remote computers by hackers. called “zombies,” compromised computers could be used to deliver illegal spam, distributed denial of service (ddos) attacks, or as servers to distribute illegal materials. if library computers are used in this way, there is a potential for a library to face legal responsibility for the actions of its computers or for the questionable materials found on them. prevention the tools needed to prevent social engineering from succeeding are awareness, policy, and training. these tools feed into one another—we become aware of the possibility of social-engineering attacks, develop policy to communicate these concerns to others, and then train others in these policies to protect them and their libraries from social engineering. libraries should have a simple set of policies to help prevent social engineering from affecting them. this policy need not be long; ideally, it should be a small page of bullet points that are easy to remember or to post near telephones. what is important is that it is easy to remember and implement when a call or e-mail comes in.4 basic guidelines for protection against social engineering ■ be suspicious of unsolicited communications asking about employees, technical information, or other internal details. ■ do not provide passwords or login names over the phone or helping the hacker? | thompson 225 via e-mail no matter who claims to be asking. ■ do not provide patron information to anyone but the patron in person and only upon presentation of the patron’s library card or other proper identification. ■ if you are not sure if a request is legitimate, contact the appropriate authorities. ■ trust your instincts. if you feel suspicious about a question or communication, there is probably a good reason. ■ document and report suspicious communications. in closing social engineering is an immensely effective method of breaching computer and network security. it is, however, entirely dependent on the ability of the social engineer to persuade staff members into providing information or access that they should not provide. with care and good information policies, we can prevent social engineering from working. after all, do we really want to be helping the hacker? the circulation desk phone rings. joyce answers, “seashore branch public library, how may we help you?” “hi there, i’m worried that i haven’t turned in all the books i have out, and i really don’t want to get stuck with a fine. could you tell me what i have out?” “no problem. what is you name?” “sean grey.” joyce brings up sean grey’s circulation records, and then remembers about the library’s information policy and decides to ask another question, “could you give me your library card number?” “i don’t have that with me. i really don’t want to get stuck with those fines.” “i’m sorry. mr. grey, to preserve patron privacy we can only give out circulation information if you give us your card number or if you are here in person with your card or id.” “but i just want to avoid a fine. can’t you help?” “don’t worry; if you are late by accident on occasion, we are willing to forgive a fine.” “so you can’t give me my records?” “i’m sorry but we have to protect patron privacy. i’m sure you understand.” “i guess so. goodbye.” “have a good day.” <click> ■ references 1. institute of management & administration, “six security threats that will

university, new york city. a review of the development of circulation systems shows two areas of change. the librarian's perception of circulation control has shifted from a broad service orientation to a narrow record-keeping approach and recently back again . the technological development of circulation systems has evolved from manual systems to the online systems of today. the trade-ojjs and deficiencies of earlier systems in relation to the comprehensive services made possible by the online computer are detailed. in her 1975 library technology reports study of automated circulation control systems, barbara markuson contrasted what she called "older" and "more recent" views of the circulation function. the "older" or traditional view was that circulation control centered on conservation of the collection and recordkeeping. the "more recent" attitude encompasses "all activities related to the use of library materials. " 1 it appears that this latter outlook is not as new as markuson had suggested. in 1927, jennie m. flexner's circulation work in public libraries described the work of circulation as the "activity of the library which through personal contact and a system of records supplies the reader with the [materials] wanted. "2 flexner went on to characterize four major functions of circulation as follows: (1) the staff must know the books in the collection, and have a working familiarity with them. (2) the staff must know the readers; their wants, interests, etc. (3) the circulation staff must fully understand the library mission and policies and work harmoniously with those in related departments. (4) the circulation department has its own particular duty to perform .... effective routines and techniques must be established by the library and mastered by the staff if the distribution of books is to be properly accomplished and the public is to have *this article is adapted from a speech delivered at rutgers university. manuscript received november 1980; revised may 1981 ; accepted july 1981. circulation systems/freedman 279 the fullest use of the resources of the institution. the library must be able to locate books, on the shelves or in circulation; to know who is using material and how the reader can be traced, if he is misusing or unduly withholding the books drawn. 3 the function of circulation has not changed since flexner's description. even within the context of online circulation systems, it is absolutely essential that the circulation system be seen in as broad a context as possible. it is not merely an electromechanical phenomenon staffed by automatonclerks. circulation services involve that function which is ultimately one of the most fundamental: the satisfactory bringing together of the library user and the materials sought by that person. it follows, then, that the mechanism and means of delivery and control of the service are only a small part, and certainly not the most important part of the circulation function. knowing your collection, your readers, and clearly knowing your library's mission are crucial prerequisites for the effective circulation of library materials. an examination of the history of circulation systems and their evolution to the present state reveals the change in outlook from a narrow view of the circulation function to a broader view. let us begin by establishing the basic elements of record keeping, upon which circulation control is based. there are three categories of records: 1. for the collection of materials, books, tapes, microforms, etc., comprising the library. 2. for the readers or users of the library service. 3. for the wedding or concatenation of the first two, i.e., the library user's use or borrowing of the library's materials. a minimal circulation model is a set of procedures or recordkeeping with respect to only the third category, i.e., records of the materials held by the library user outside of the library. a total or complete system would then be one that provides for all three categories. using these criteria to judge the level of control provided by the various circulation systems of the past, let us review. the earliest method of circulation control was the chain method. in this case, "circulation" is not an accurate term; "use" of materials is more appropriate, as the collection did not circulate. books were chained to the wall and the user did not take the material outside of the library. the minimal circulation model is not met, and records were not required. several hundred years later, the ledger system's first iteration involved a simple notation into a ledger. the identification of the book-call number and/or author and title-and the borrower's identification were recorded. upon the return of the book, the borrower or the receiving clerk initialed the ledger entry or otherwise indicated the return of the item. minimal circulation control is met. a more developed or sophisticated ledger system exceeded this minimal circulation model. the new ledger had each page headed by a different 280 journal of library automation vol. 14/4 december 1981 borrower or registration number. consequently, a given user had all of his or her charges recorded on the given page indicated by the user's number. the economy of not having to write the borrower's name for every transaction was made possible through the creation of a file of patron records linked to the ledger page by common registration numbers. in effect, this was our first "automation." the use of a master file in support of anumbered page provided information that had previously been handwritten every time someone wished to borrow books from the library. the new ledger system also allowed for a more orderly control of charges. only the borrower's number was needed to get at the page of transactions relating to that borrower, as opposed to the former methoda benchmark method, in a sensein which the transactions were chronologically entered and had no other ordering whatsoever. even with the improved ledger system, though, the only ordering was by borrower number and date of issue to the borrower. there was no arrangement that provided for sequencing or finding the books borrowed. the need to identify borrowed books led to the dummy system. every book had a concomitant dummy book (or large card) that had a ruled sheet of paper with the book identification information on it and the borrower's name and/or number. when a user wished to borrow a book, the dummy was pulled from a file and the borrower information was written on the sheet of paper. the dummy was then filed on the shelf occupying the space formerly occupied by the book itself. when the book was returned, it was reshelved, the dummy removed, and the circulation transaction was crossed out. this system is interesting in that it provides for a complete inventory control. either all items are on the shelf in proper sequence or a physical surrogate or record for circulating items is substituted and placed in proper sequence. one has instant and, in effect, "online" access to the presence or absence of materials if one has the call number and can go to the shelf. unlike most systems that can only tell whether or not the book is present, the dummy system tells who has the book and when it was charged. in terms of a minimal model, this system provided less and more than the ledger system. if a reader wanted a list of books he or she borrowed, the reader would have to view every dummy and see if the listed item was charged to him or her. in contrast, the ledger system served such a request well, though every page of the ledger might have to be examined to find out who had borrowed a book not found on the shelf. leaping past several systems, let us now discuss the newark system , the overwhelmingly prevalent system in the united states today (if we include the mechanical or electromechanical versions of dickman, gaylord (the manual, not automated), and demeo). the newark system incorporated the best features of the systems already mentioned. a separate registration file was kept which provided both alphabetic access by patron and numeric access by patron registration circulation systems/freedman 281 number. consequently, the recording of the borrower's identification during circulation transactions only involved the notation of the number. for book identification, a card and matching pocket were placed in each book with the call number and/or author-title identification information. the circulation transaction involved the removal of the card from the pocket and the entering on it, ala dummy system, the date of the transaction and the borrower number. the cards for all of the books borrowed on a given day were aggregated and filed in shelflist sequence in a tray headed by the date of the transactions. resorting to computer jargon, the major or primary sort of the book cards (read circulation cards) was by date, but the minor sort was by call number. consequently, if one wanted to know the status of a given book and one had the call number, it would not take too long to search, even with a file as large as the one in the main branch of newark public library, by looking for the item in all of the different days' charges. when a book was returned, the clerk noted from the date-of-issue card inserted in the book's pocket, the tray in which to search, and the matching call number on the pocket which was used for discharging the book, i.e., removing the charge card from the tray and replacing it in the book. the combination of the books on the shelf plus the cards in the different trays in shelflist order constituted a complete inventory. additionally, the trays of cards comprised a comprehensive record of all current charges, i.e., all transactions by date, call number, and borrower, with borrower number pointing to fuller information in the registration file. looking back at our basic model, the newark system offered not just the minimum-a record of the item and the borrower who took it-but also introduced a major step toward inventory control. there was an inventory sequence involved, or, more accurately, several inventory sequences-one for each given collection (or day) of circulation transactions. what was still missing was a record by borrower of what was charged to him or her. in the original newark system, the borrower's card had entered upon it dates of issue and return of items. this way, even if the library could not tell the user what items (s)he had, the user's card would reflect the number of items outstanding. the handling of reserves, renewals, and overdue notices occurred as follows: a colored clip or some indicator on a circulation card would be used to indicate a reserve. a renewal would be handled the same as a return except the person would wait while the charge card was pulled from the appropriately dated tray, and assuming that no reserves had been placed on the circulation card, the book would be recharged (i.e., renewed) to the borrower. overdues automatically presented themselves by default. cards left in a tray after a predetermined number of days represented charges for which overdues were to be sent. the tray was taken to the registration file and the numerically sequenced registration cards for the delinquent borrowers removed so that notices could be prepared and sent. then the 282 journal of library automation vol. 14/4 december 1981 registration slips and circulation cards had to be refiled at the completion of the process. essentially, most subsequent systems are variants on the newark system. the mcbee key-sort system involves the use of cards with prepunched holes around the edges, one of which can be notched to indicate the date an item is due. the cards are arranged by call number creating a single sequence. the insertion of a knitting needle .like device through a given hole will allow all of the books overdue for a given date to fall free of the deck. this system is like the newark system in that it has inventory and date access, but unlike newark it places a horrible burden on the borrower. each card has (written by the borrower) the borrower's name and address and the call number, author, and title of the book. thus, the library is saved the labor of creating circulation cards and maintaining registration records for every patron-all of the information needed is on the charge card. but here, as marvin scilken has pointed out, the burden of the library's tasks are merely passed on to the users. this point should be emphasized. the next system to be considered is the photo-charge system. microphotos are taken of the borrower's card, which has the name and address on it, the book card (as in the newark book identification card), and a sequentially numbered date-of-issue or date-due slip . again, as with the mcbee, since the photo record includes the borrower's name and address, one can throw away registration files. also, a list or range of transaction numbers is kept by date used. since the numbered date-of-issue slip is placed in the book at the time of charging, and one removes it when the book is returned, it is a simple step to cross off or remove the number on the slip from its corresponding duplicate on the list of numbers for that day's transactions. overdue transactions are found by searching for unchecked transaction numbers on the numerically sequenced microfilm. this system does meet the criterion of the minimal model, a record of the user's use of the item. in terms of labor intensity, one has eliminated the maintenance of charge-card files and registration files by a single microfilm record. reserves, though , are terribly time-consuming with the photo-charge system: each returned book, before it can be returned to the shelf or renewed, must be searched against a call-numbered sequence of reserve cards. academic libraries would not use this kind of system because call-number access is a necessity, especially in relation to recalls of longloaned items . the elimination of paper files is what so commended this system to public libraries over the newark-based systems. but, as was noted, one has virtually no way of determining who took a book out or when it is due back except, in principle, by searching all of the reels of microfilm. some variants on this microfilm system were developed. bro-dart marketed a system that thermographically produced eye-readable records instead of microimages . such was the state of circulation systems before computers began to be used. the following-a discussion of the involvement of computers-can circulation systems/freedman 283 be separated by the type of hardware: main frames, minicomputers, and microcomputers. the main-frame computer has been used primarily in the past as a processing unit for batches of circulation transactions collected and fed to it via punched cards, terminals, or minicomputers. call number and author and title (albeit brief) and user identification number, were captured for each transaction. in the 1960s and into the early 1970s, this information would be batch-processed by the computer and a variety of reports would be produced. what the computer does, then, is keeps track of numbers, their ranges, and the dates of the ranges. but the computer can do much more than this. it is capable, as none of the nonautomated systems were, of rearranging the data input and then comparing and tabulating them as desired and appropriate. consequently, the fact that the call number, author, and title are stored by the machine means that lists or files can be arranged by any of these elements. the same goes for date of transaction. as to borrower identification number, a master file much like the newark registration file is kept (only now in its machine-readable form), and the computer does the comparing at high speed instead of the clerk taking the charge record and going to the numeric file to find the name and address of the borrower. of course, the computer can then readily and quickly print out overdue notices with an obvious absence of clerical support and labor intensity. as we all know, the rate of increase of labor costs in increasing, and the rate of increase of computer costs is decreasing. two kinds of large computer systems have been used. the batchoriented one, which either kept track of items in circulation only (the absence system-only items absent from the collection were tracked), or one that kept track of the entire collection (the inventory system). 4 normally, identification numbers were used for patrons in either system. although relatively rare in academic and public libraries, the mainframe-based online system is also in use. ohio state university is famous for its online system. what is meant here is that all transactions are immediately recorded and all files are instantly updated. printing is still necessary for overdue notices, but printed circulation lists are not necessary because of the online answers to queries regarding books or patrons now possible through terminals distributed to appropriate locations. the minicomputers came on the scene in two stages. clsi's entrance in 1973 utilized one of the early minicomputers, quite small by today's standards. for relatively small libraries that had not begun to dream of having their own computers, it became possible to have an entire inventory (in abbreviated form) and an entire patron file online. consequently, all of the access power of the newark system, and none of its labor intensity, was available online and much more besides. few libraries could afford the main-frame system of ohio state, but many could pay for clsi's, and indeed they did. in the last few years, minicomputers have grown several magnitudes 284 journal of library automation vol. 14/4 december 1981 above the capacity and speed of main-frame computers of the 1960s. consequently, such firms as dataphase, systems control, geac, gaylord, and others offer these larger minis, which can now support online the needs of large branch systems with inventories of hundreds of thousands of books. incidentally, clsi, with a new mini line, can do this now as well. both the miniand maxi-based systems do all of the basic work originally outlined: the whole inventory can be accessed online or with printed lists arranged by author, title, or call number (and, presently, some vendors offer online subject access and cross-references); access can also be made by patron's name. further, the basic transactionitem, borrower, and date-is recorded and checked for holds or delinquency before it is accepted. without overly extolling the present state of the art, it should be said that all of the information identified as important in the earliest systems is now not only available in a far quicker and more usable fashion, it can be manipulated by the machine in a variety of ways to meet and serve management objectives not considered practicable in the past. peter simmons showed how collection development could be aided by automatically generating purchase orders when reserves exceeded a specified acceptable level. 5 all kinds of statistical data regarding collection and patron use can be generated that could not have been possible in a manual mode. while at the university of southwestern louisiana, william mcgrath was able to adjust book budget allocations in terms of collection use and undergraduate major in a most interesting fashion. 6 the net result was an empirically based expenditure of book funds. now the microcomputer or microprocessor is the newly emerging phenomenon , and in many respects it is not unlike the minicomputer of the early 1970s. it is being used to perform single data-recording functions, and is also being seen as the link to the larger computer . so we have moved from chained books to microcomputers the size of a desk top. originally, a great deal of information was captured at great expense and laboriously maintained. certainly the handwritten and typed records of the newark system, although relatively comprehensive, were obtained and preserved at great cost. and, despite it all , there were real limitations of access . the succeeding mcbee and photo-charging systems appreciably cut out-of-pocket costs to the library, but either passed labor directly on to the user, or eliminated access altogether. book or patron access are virtually impossible with the photo-charging method. simply put, that system tells what is overdue, and that's all. the entry in the 1960s of the computer radically altered the ground rules. now all sequences of encoded elements are possible, and management information can be derived. important statistical data pertaining to collection use and library users can be obtained by further manipulating the data accumulated in the circulation process. it is now possible for all but the smallest and the very largest libraries to have access to and control circulation systems/freedman 285 of their materials through the current range of minicomputers on the market. jennie flexner told us that circulation had to be more than maintenance and record keeping of loan and borrower transactions. through the advances of the computer technology and its application to circulation control, we have finally seen what seems to be an optimization of the recordkeeping process and, by extension, an improvement in circulation service. if instantaneous access to patron files, inventory files, and outstanding transaction files through a variety of modes and computer-developed management data does not constitute that optimization, it will have to dountil the real thing comes along. acknowledgment the author is deeply indebted to susan e. bourgault for her editorial assistance. references 1. barbara evans

as the technology & growth specialist for the four counties of the mohawk valley library system in schenectady, new york. prior to this position, mary dedicated over 15 years to teaching digital literacy and technology trends at the clifton park-halfmoon public library, a suburban public library that has over 40,000 registered patrons and 1,500 visitors per day. the community has a strong presence in youth and family programs and is a popular place for teens and children to learn, play, and create. in 2015, she began offering coding and stem classes to children and teens at the library and in the community as outreach programs. mary will share her expertise in technology programming for children and teens and the importance of planning, preparing, and testing curriculum for coding and robotics classes. introduction when you get unsolicited input from the community, it is worth the effort to investigate. rather than say “that will never work here,” take the time to listen. is this the voice of one or of many? at the clifton park-halfmoon public library located south of saratoga springs and north of albany, new york, our 55,000-square-foot library serves two communities with a combined population of 64,575 and hundreds of visitors from the greater capital region. as a digital services trainer my focus was geared toward teaching computer classes to older adults. my pace was slow, steady, and empathic as i translated this world of technology into digestible “bytes” for everyday use. i could easily relate to the foreign language these tools presented since i did not grow up with technology. this community of learners grew steadily between 2007 and 2014, particularly when more and more people were buying e-readers, tablets, and smartphones. i found my niche, i was making a difference, and i was comfortably coasting. i was fortunate to be in a community that used new technology and valued learning. after all, they had free access to a variety of computer classes and one-on-one assistance at their local library. the digital literacy foundation grew and was strong in the community after finding the support needed; however, over the years, i was getting antsy as i reached a plateau. my new challenge was passed on to me in a loose net, rather than on a silver platter. a cub scout leader approached me as his son was “aging out” of scouts, that transitional period between fifth and sixth grade. he recommended the library start a coding club, and he was willing to help. coding was an area i knew very little about as a technology discipline, and working with children would be a new challenge for me, but i was ready to jump right in. what started out as a few weeks of experiential learning, turned into seven years of coding and robotics classes for third mailto:mcarrier@mvls.info information technology and libraries june 2023 community-driven programming 2 carrier grade through high school students with the addition of programs for kindergarten through second graders in later years. the process to initiate a coding club started in 2015 with research and fact finding. i gathered information about computer science and coding, including the benefits of learning computer science at a young age, methods to teach these skills, and websites and resources to help with the development of the curriculum. with data in hand regarding resources, benefits, and age recommendations, my supervisor and i sat down with the parent and brainstormed the best way to approach offering a coding club that would be beneficial to the community and manageable from our perspective. we decided to offer a six-week series and called the club code crew. fifth through eighth graders were invited to register for this two-hour after-school program with a goal to create projects in scratch (https://scratch.mit.edu/), which uses block programming. each team of two to three students worked on a project to highlight the benefits of using the library. teams created interactive stories about finding a favorite book, checking out materials, and highlighting the library’s programs, such as story time. at the end of the six weeks, each team presented their project to an audience of family members and staff. the goal was to learn how to code in scratch, create a final product to promote the library, collaborate, and have fun. code crew was just the beginning. from there, our library offered a variety of series and one-time classes in scratch, scratch jr., python, css/html, and javascript. here’s what i learned along the way… planning your program set your goal to offer coding curriculum to children, teens, and/or adults. some of our main goals were to emphasize the importance of computer science, to allow children the opportunity to create versus consume computer games, and to promote collaboration and confidence. research what programs and resources are already available and where in the community. check with local schools from elementary to high school, continuing education programs, youth organizations such as the ymca, and summer camps in your local community. if there are other programs currently offered, who are the participants in the program? are there restrictions or limitations? for example, is coding offered only to accelerated students or available to all children? is it restrictive due to participation fees? this research will indicate if there is a local offering. a free program at the library is more inclusive. design based on what you investigated, would this work in your community? in your design, who is your audience, what skills will they need, and what is the recommended age based on your review? what is your capacity for a class, or class size? consider the number of computers or laptops and the number of students that is manageable based on the age of your audience. who will run the class? do you have staff that are interested and available, or do you need to outsource this program? how much do you need to budget? we were fortunate that the parent with the original idea had a programming background. he started as a volunteer and quickly became a contractor as we added more and more classes. https://scratch.mit.edu/ information technology and libraries june 2023 community-driven programming 3 carrier investigate program content reviewing coding websites, curriculum, or lesson plans can help with successful preparation. generally, these three websites are popular, well-known coding websites. more specifically, they are my top picks because they appeal to different learning styles: • scratch coding: https://scratch.mit.edu/ • code.org: https://code.org/ • cs google first: https://csfirst.withgoogle.com/s/en/home there are tutorials that include written instructions, video instruction, and exercises for different skill levels from beginner to advanced for students. these tutorials all include beginner block programming that use a drag and drop method to click blocks of code together. children are guided through colorful, themed tutorials in logical order for learning. by creating a user account, students can save all their projects and progression for another class or to continue at home. each website has different benefits. i started with scratch (https://scratch.mit.edu/) as it is the most widely used (created in 2007), has an unforgettable logo (scratch the cat), and provides helpful tutorials to use in class. after learning the basics of moving scratch, adding loops to repeat actions, and changing the backgrounds and sprites (characters), children are ready to make their first pong game. animating sprites to talk to each other and change scenes is the next fun basic element to try. participants love seeing the conversations develop and sharing their stories with each other. we used code.org (https://code.org/) to help promote the benefits of computer science by showing memorable videos in class that have celebrities, sports figures, and social media creators expressing their positive experience of learning to code. code.org promotes an hour of code challenge every year during computer science education week, which is the first week of december. kids love this website because it uses popular and current themes, such as characters from the movie frozen, star wars, and minecraft. google cs (computer science) first (https://csfirst.withgoogle.com/s/en/home) launched in 2013 and is a website used for classroom style collaboration. as an instructor, you can choose to use google classroom to encourage sharing, and collaboration among participants, and to review an individual’s progress. the exercises and videos are incredible and support learning that continues to build skills with exercises defined as beginner, intermediate, and advanced. it uses scratch block programming with easy-to-follow lessons to use with a class or for self-paced learning. design and test design the curriculum and lesson plan for the class. think project-based. plan an introductory exercise that builds to a project. do a test run. bring in a few volunteer students and run through the lesson plan or run a pilot program and adjust based on the results. consider skill level and attention span. how will you accommodate this? i learned to be prepared with additional projects to offer students who finish early. give them time to explore. ask students https://scratch.mit.edu/ https://code.org/ https://csfirst.withgoogle.com/s/en/home https://scratch.mit.edu/ https://code.org/ https://csfirst.withgoogle.com/s/en/home information technology and libraries june 2023 community-driven programming 4 carrier to help each other and stick to completing the project. the project should be fun and easy enough to get them excited about coding. assess and adjust coding is not for everyone. assess what went well and what you may want to change. don’t take it personally if students didn’t like it or don’t return. some children and teens feel overwhelmed when they feel their skill levels are below others. encourage them to watch the video tutorials and start with the basics, like google cs first step-by-step video tutorials. figure 1. google cs first lessons. figure 2. scratch for cs first. information technology and libraries june 2023 community-driven programming 5 carrier after introducing and running a coding class for a while, you will have a built-in following and enthusiasm in your community. a natural progression is to start working with robots. the coding that has been successfully run on a computer screen can now be applied to an object. children have learned the general concepts of block programming, which is directly applicable to the coding used to control robots. loops, conditionals, and various commands can be programmed to bring the robot to life. robots love to dance, do obstacle courses, race, and “dress up.” each of these robots are compatible with block programming such as scratch and object-oriented programming languages such as python. three types of robots are used for classes at the clifton park-halfmoon public library. figure 3. robots used for classes. finch robots we purchased the finch robots (https://www.birdbraintechnologies.com/) first because they were priced reasonably below $100. they came with a long cable that tethers to a laptop and each is coded through a free download scratch 2.0. newer finch models are available and use a blue tooth connection. there are video tutorials and lesson plans available on the bird brain technologies website. these can be used for grades k-12. dot & dash robots there are apps, challenge cards, and curricula available on the wonder workshop website (https://www.makewonder.com/). these robots are best for grades k-8. makeblock – mbot makeblock includes activities and lesson plans for pre-k-12 (https://education.makeblock.com/). one of the most important components of working with robots is to research what is needed to run the robot. typically, there is an app or download required. whether you use a laptop, chromebook, or tablet, planning and preparation is key. we purchased six kindle fire tablets to use with the mbots and found that the blockly app needed was not available as a download. i was able to run a hack to allow me to download the google play store app, but with a little more research, this could have been avoided. give yourself time before offering a program to test, test, test. and even then, you will adjust and learn along the way. finch robots dash & dot makeblock mbot https://www.birdbraintechnologies.com/ https://www.makewonder.com/ https://education.makeblock.com/ information technology and libraries

present their projects. • utilize students as classroom helpers as they gain confidence. • continuously assess and adjust your plan. • growth takes time, keep building the program, and move forward as long as there is interest. the library community’s strong presence and support for youth and family programs made this programming endeavor successful. as interest in the program grew, i hired two part-time librarians and a parent as contractors. the community response allowed us to develop curricula for k-2, 3-5, and 6-adult. figure 5. chart shows the breakdown of attendance by programming topic. scratch was targeted for third to fifth graders; ready-set-code for kindergarten to second graders, and python programming for fifth graders to adult. total attendance for children and teens

beyond the library walls. outreach was offered through afterschool enrichment programs and participation in our annual district-wide science and health discovery night, a showcase of science, technology, engineering, math, and health exhibits and interactive demos for all ages. volunteer exhibitors from a variety of companies and organizations participate and draw an audience of more than 3,000. we also allowed six out of sixteen of our finch robots to be borrowed by teachers and community members for at home learning and play. our success was worth the effort. there is nothing better than when you hear the squeals of delight, see the pride in the creator, and witness collaboration. abstract introduction planning your program design investigate program content design and test

libraries have long consulted with faculty and graduate students on ways to measure the impact of their published research, which now include altmetrics. podcasting is becoming a more viable method of publicizing academic research to a broad audience. because individual academic departments may lack the ability to produce podcasts, the library can serve as the most appropriate academic unit to undertake podcast production on behalf of researchers. the article identifies what library staff and equipment are required, describes the process needed to produce and market the published episodes, and offers preliminary assessments of the podcast impact. introduction the academic library has always had an essential role in the research activities of university faculty and graduate students, but until the last several years, that role has primarily focused on assisting university researchers with obtaining access to all relevant published research in their fields, making it possible for those researchers to complete a thorough literature review. more recently, that role has evolved to encompass assisting with other aspects of research and publication, including consulting on copyright-related issues, advising researchers on the most appropriate places to publish, preserving publications and data in institutional repositories, helping tenure-track faculty to evaluate their research impact as part of the tenure and promotion process, and hosting open-access journals. meanwhile, libraries of all types have experimented in the last ten to fifteen years with using social media to promote library collections, services, and events. many libraries have taken advantage of facebook, twitter, and youtube as part of these efforts. increasingly, libraries have incorporated makerspaces so that library patrons can create and edit video and audio files, meaning that this same equipment and software is now available to librarians and other library staff for their own purposes. this has resulted in libraries producing promotional videos and podcasts. the dramatic increase in mobile technology (smartphones and tablets) ownership and usage over the last decade has resulted in an increase in the consumption of podcasts wherever the listener happens to be when their ears are not otherwise fully occupied, such as commuting, exercising, and engaging in home chores. as a result, academic libraries are now finding themselves in an excellent position to use podcasting for instructional and promotional purposes in an effort to reach a broad audience. what happens when the university library combines its inherent interest in supporting the promotion of faculty and graduate student research with its ability to create podcasts to quickly and inexpensively reach an international audience? this paper documents the efforts of an academic library at a high-level research university to partner with one of the university’s mailto:dsmith@usf.edu mailto:mlcook3@usf.edu mailto:torrence@usf.edu information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 2 academic departments to use podcasting to promote the research done by that department’s faculty and doctoral candidates. we will describe which library staff were involved, how the podcast was planned, the execution of the podcasting process, the issues that were encountered throughout the process, and how the impact of the podcast was assessed. calling: earth, the podcast produced by the university of south florida (usf) libraries, can be found at http://callingearth.lib.usf.edu/. literature review podcasting as a means for promoting scholarly communication is a relatively new and uncommon idea in a library setting, therefore the extant literature is scarce on the subject. a high percentage of the contemporary articles on the aforementioned topic focus on the use of podcasts as a means to satisfy a wide array of student learning needs. while pedagogical best practices knowledge is useful, what current literature does exist is not an exact match for the concept of promoting scholarly communication, which offers subject specificity, faculty and graduate interaction, marketing of libraries, and research visibility as aggregate goals. what follows in this literature review is a summary of a slice of the literature related to podcasting, academia, and/or libraries. the researchers chose as a starting point to look at the general use of podcasting, as well as social media, in various academic and library environments. in a recent article on the use of social media and altmetrics, for example, the increased use of these tools is outlined, but with numerous caveats regarding the initial non-probabilistic methods of gathering information on the how and why of their adoption.1 to further emphasize the use of podcasts and, in a related way, social marketing, an examination of an article related to association of research libraries (arl) efforts in this vein was examined. a comprehensive study of arl member libraries published in 2011, with not much on this topic published since this date, demonstrated in figure 1 of their research that five of the 37 respondents contained recorded interviews and only one included scholarly publishing content.2 this ten-year vacuum in further research was unexpected but indicates an opportunity for a new type of podcast focusing on academic production. scholars in academic libraries have long examined student preferences for new technologies and types of information transfer, including the use of podcasts. a study from sam houston state university found that 36 percent of users in 2011 were using podcasts for recreational purposes as opposed to much lower use for academic and scholarly communication benefits. 3 in the future, academic creation and utilization of podcasts for scholarly communication is ripe for a hearty statistical and qualitative analysis. specific to this inquiry, the application of podcasts for scholarly communication in a subject discipline present in the literature appears to be lacking. furthermore, this literature review emphasizes the dearth of research that relates to promoting the research efforts of geosciences faculty and graduate students. in terms of recent literature, there are also a number of publications available that deal with the history and evolution of podcasting in education and, specifically, higher education. one such current work provides an excellent outline of this growth in use, as well as outlining several major types, or genres, of podcasting in these types of environments. following a strong and succinct overview of the technology and its use in college and university settings, the author continues to effectively define, with examples, the three main genres they have identified: the “quick burst,” the “narrative,” and the “chat show.”4 the model that most represents usf’s calling: earth program is “narrative,” as this includes a subcategory of “storytelling.” this work is truly beneficial for any group or individual developing, or improving, an educational podcast effort. http://callingearth.lib.usf.edu/ information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 3 in 2011, peoples and tilley outlined the emergence of podcasts to disseminate information in academic libraries. one of the excellent questions that arises from this work deals with the access, advancement, and archiving of the content; is this content to be archived, or cataloged, as more permanent material, or is it electronic ephemera?5 this is a question for the usf calling: earth podcast group going forward as the level and quality of content and, ideally, use is expanded. additionally, educators are studying more about the limitations of podcasts; not to rule them out as academic tools, but to inspire and enhance the best possible outcomes. one excellent warning to be heeded by any library hoping to utilize podcasts for education and dissemination of research is summed up well in this quote: “if students do not utilize or do not realize the benefits of the selfpacing multimedia characteristics of podcasting, then the resource becomes a more likely contributor to cognitive overload.”6 there have been a small number of the quantitative elements of podcast use in academic libraries. an article in vine: the journal of information & knowledge management systems outlined, via content analysis and other methods, various unique and shared characteristics of existing academic podcasts, while also furthering the concept of podcasting as a “library service.”7 this may not have been the first publication to make this assertion, but this is a view that is also held by these authors and this view shapes the development and advancement of the usf libraries podcasting efforts. librarians of all types must be wary, however, as there are numerous articles that focus on the better understanding of student learning preferences. as presented by a recent article on the success of satellite and distance learners showed, though, these tools often hit the spot on the delivery preferences for these types of students.8 switching gears to a bit more topic specificity, a number of news and academic articles were identified on the use of podcasts in areas of the geosciences. one such effort is th e geology flannelcast. the development and implementation of this combination of education and entertainment, which is also a goal of these authors, is outlined by the creators’ poster presentation at a recent geological society of america conference. with a focus on the increasing ease of podcasting technology, reduced cost of equipment, and the use of “conversational atmosphere” within a pedagogical framework, this model stood out as one worth studying.9 furthermore, the geosciences are, or can be, interesting and exciting. a recent podcast on communicating geosciences with fun and flair is just the encouragement this research group needed to go all-in on this project. and that the geosciences are far from boring!10 as is evidenced by an examination of current and historical literature on this topic, there are multiple opportunities for further exploration and library efforts, expressly as one of the main points of this work is to emphasize faculty and graduate research efforts and scholarly communication and original content creation. in addition to the focus on these publications and presentation efforts, the results will be measured by the initial assessment projects including download and utilization data and, hopefully, positive feedback from participants and library administration. further measurement is expected to demonstrate advanced citation counts and downloads of the publications of the faculty and graduate student interviewees. it will be correlation and not causation, of course, but the team hopes to have positive feedback for participants and the library. information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 4 staffing as with any successful project, a project to produce a podcast focused on academic research had to begin with individuals who had either the interest or the expertise, ideally both, to initiate the work. one was an associate librarian with more than 13 years of experiencing in producing regular podcasts, while the other was a library staff member who was a doctoral candidate serving on the usf libraries research platform team (rpt) for the usf school of geosciences. the rpt was already tasked with assisting the geosciences faculty and graduate students in maximizing the impact of their work and had been using various means in order to accomplish this, such as an institutional repository for research output, and tools to measure the impact of previously published work. during a conversation in late 2018, the librarian suggested to the rpt staff person that podcasting could be used to promote research to a variety of audiences, including usf faculty and students, faculty and students at other universities, k-12 science teachers, and members of the general public (both local and beyond). the librarian offered to initiate the podcast and train the rpt staff on how to continue the podcast after a number of episodes had been produced. the librarian brought to the project the needed expertise with launching and maintaining a podcast, while the rpt doctoral candidate was already familiar with the geosciences faculty and other doctoral candidates and could identify those who would make good candidates for being interviewed about their research. planning the initial planning for the podcast began approximately two months before the first episode release. the original project managers and podcast creators met a number of times to discuss logistics, equipment, and staffing needs, and to agree upon a podcast name (calling: earth). since the notion of podcasting for researcher promotion was an unexplored territory, the support from higher administration was cautious. however, after production of the first episodes, traction behind the podcast grew and additional support for future endeavors was received. the podcasters acquired handheld recording equipment, a tascam dr-05 linear pcm recorder, from the usf libraries digital media commons and tested it out in multiple environments (for instance, a quiet office versus a recording studio) to find the optimal location to record the interviews. we found the hand-held recording equipment worked well in a quiet office and allowed for travel to the researcher’s office if they requested. the podcast creation team discussed how to add intro and outro music to the podcast that would not violate any copyright restrictions but that would fit the mood of the podcast. th e rpt staff person knew of a local tampa-based band, the growlers, as a potential source for music because the bass guitarist was an adjunct professor and alumnus of the usf school of geosciences. the alumnus gave permission to use a portion of the band’s recorded music for the podcast. a hosting service was needed to host and publish the podcast. the librarian suggested using libsyn, because of their 13 years of previous experience with the platform, libsyn’s inexpensive hosting plan, and the ability to acquire statistics including the geographic locations (countries and states) where the podcast was being downloaded. information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 5 execution potential interviewees were contacted via email and invited to be interviewed. once the potential interviewee agreed, a time and a place to conduct the interview was agreed upon. the rpt staff person determined what the most recent research was for each interviewee, and then pro vided that content to the librarian host for review. the host then prepared interview questions based on the research content. the host went over the questions with the interviewee before the interview began to clear the content with the interviewee and to make sure everything would be covered in the interview that the interviewee wished to cover. the interviews took approximately 30 minutes to an hour. editing of the podcast was done using garageband, allowing for the addition of the music to the beginning and end, as well as the host introducing both the general podcast and the specific episode, identifying the academic units involved in the podcast, indicating how listeners might provide feedback, and thanking the music group for allowing the use of their music. in a few rare cases, small interview segments were removed, usually due to the interviewee feeling that it did not represent them well. challenges as with any new endeavor, challenges were faced at all stages in the process of getting the podcast to production and beyond. buy-in from library administration an early challenge was to gain buy-in from the library administration. this began with requesting that the library fund the hosting service, and the feeling of the administrator was that it was a worthwhile experiment, at least in the short term. once a number of episodes had been produced, the library administration had a better sense of the quality of the production and how it would serve the interests of the library in its academic support role. lack of budget with no budget for this project (beyond the administration’s monthly payment of the hosting service), the podcasters were at the mercy of the quality of the recorders available for library checkout. if the recorders did not produce a high-quality recording, the podcast would possibly lack the sophistication needed for production. also, high-quality graphics work was needed and required us to look into other library units for help with creating a logo. getting the podcast into apple podcasts once content was being produced and published, it was time to submit the podcast to apple podcasts. apple initially rejected the submission because the first logo looked very similar to an iphone. it should be noted that apple did not supply a specific explanation of what copyright was being infringed, so the podcasters were faced with making a best guess as to what the problem was. based on our assumption, we changed the logo and resubmitted the podcast. a further problem arose when apple required that the new submission use a different rss feed than the original submission. eventually the podcasters sought assistance from libsyn, who explained how to make a minor change to the url of the rss feed so that the podcast could be successfully resubmitted. information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 6 new logo creation the first logo continued to be used for the entire first season, but before the second season was released, the library’s new communications and marketing coordinator assisted with the creation of a new logo that looked more sophisticated and more in-line with other podcast logos. having an in-house graphics designer was extremely helpful in rolling out a new logo (see figures 1 and 2). figure 1. season 1 logo figure 2. current logo setting up interviews identifying potential interviewees, requesting interviews, and setting good times and locations for the interviews brought on another batch of challenges. the usf school of geosciences is composed of geologists, geographers, and environmental scientists so when planning out the schedule for the potential interviewees, an effort was made to involve a wide range of researchers. some potential interviewees denied the request altogether, while others were not available for the needed time period. given that the podcast was released every two weeks, there was a little wiggle room for scheduling hiccups, but once or twice a last-minute request to a new potential interviewee was made to ensure production stayed on schedule. where the interview was held and what time required a lot of back-and-forth emails between the rpt staff person and the interviewee. preference on time and location was given to the interviewee, but it was requested that, if they did not want to come to the library to be interviewed, their own office/lab space could be used if it was a sufficiently quiet environment for recording purposes. comfortability of the interviewee once an interview began, the challenge of engagement from the host and comfortability of the interviewee became apparent. the host had to engage the researcher at a level appropriate for a general audience, which was challenging given that the research done by the usf school of geosciences is often at a high-level of critical thinking and problem-solving. to add on to the complexity of the research being explained, the comfort level of the interviewee had the potential information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 7 to dampen the interview. one researcher was so uncomfortable speaking in an interview that they typed up in advance what they wanted to say. assessment libsyn statistics according to libsyn statistics (as of july 17, 2020) there were a total of 3,593 unique downloads from 48

preliminary survey and scholarly impact a survey was sent out to the interviewees to gauge their impressions of the podcast and to see if they had noticed any impact to their citations or document downloads. our goal for the survey was to find out if the podcast was accomplishing the intention for starting a podcast, which was to increase researcher impact by research dissemination, as well as to inform the podcast processes and procedures. the questions asked were: 1. in what ways do you view the calling: earth podcast as a way to positively affect your research impact? 2. what evidence do you have, if any, to suggest your research has been positively impacted because of being an interviewee on the calling: earth podcast? 3. what would you have liked to be different about your interview process for the calling: earth podcast? 4. what suggestions do you have for the future seasons of the calling: earth podcast? for example, should the format change, the focus be different, change the length of the interview, etc. furthermore, each interviewee was asked to contribute their scholarship to the library’s institutional repository, scholar commons, to allow for the archiving of their research publications and to use as a means of tracking scholarship impact as a result of the podcast. once an interviewee’s scholarship was placed in scholar commons, a selected works profile was created so that a direct link to the scholar’s work could be disseminated through the podcast notes. impact on faculty has also been noteworthy. the download totals for faculty interview participants (when comparing roughly the same amount of time just prior to and following their published interview) showed an average increase of 30 percent and suggest a strong correlative link between the podcast and researcher impact. furthermore, anecdotal evidence from interviewees such as “puts my name out there to a wider audience,” “enhances the visibility of my work,” and “allow others to hear about [my research] in a more passive way” indicates the potential impact a researcher can see from being a part of the podcast. a second survey was sent to the faculty, students, and staff of the entire school of geosciences to determine who was listening to the podcast and conversely, who was not, and their reasons for listening or not listening. the survey contained five questions in total, but according to how the participant selected their answers, not all were available to be answered (figure 3). the first question asked their status in the school of geosciences (faculty, staff, undergraduate, graduate, or other). the second question asked if they had heard of the podcast and if they had or had not listened to it. if a participant chose the option that they had never heard of the podcast, then the survey ended for them. if a participant chose the option that they had heard of the podcast, but had not listened to it, then the survey directed them to a question that asked them to provide reasons they had not listened to the podcast. if a participant chose the option that they had heard of the podcast, and had listened to at least one episode, the survey directed them to a question that asked how many episodes the participant had listened to and for what reasons were they listening to the podcast. this data was collected to inform the future direction of the podcast. information technology and libraries september 2020 making disciplinary research audible | smith, cook, and torrence 9 figure 3. flow chart for the entire school of geosciences survey checklist for podcast planning/execution based on our experiences in the production of the calling: earth podcast, we recommend that academic librarians and library staff use the following list to help with planning and executing the production of their own podcasts: • get general buy-in from library staff and administration, and update as the planning progresses and budgeting is needed. • decide on goals, audience, content, format, frequency of production, and methods of assessment. • work with media staff to design marketing, including podcast title (avoiding duplication with other podcasts) and logo development. • choose a podcast hosting service. • identify relevant staff for hosting, recording, editing, and publishing and train as needed. • evaluate existing hardware and software and make additional purchases as needed. • contact potential interviewees and create a schedule. • prepare customized interview questions and share as appropriate with interviewees. • record interviews. • edit and publish episodes. • submit podcast to apple podcasts, spotify, and other popular podcast directories. • monitor statistics. • continue to engage in marketing and assessment activities. what choice best describes your current status in the usf school of geosciences: which of the following describes you: i have never heard of the calling: earth podcast i have heard of the

torrence 10 conclusions and future directions enthusiasm and anecdotal positive feedback are enough fuel for current activities and levels of enthusiasm and the future of podcasting in libraries also appears open and exciting. at the usf libraries, calling: earth is currently in its third season and with each new episode, new ideas and increased archival content become a permanent part of the library’s legacy and collections. this is another area ripe for future exploration, as this type of original content is archived, cataloged, and disseminated, becoming another part of regular academic impact measure. in this vein, the usf libraries podcasting group plans to further codify cyclical assessment tools, including the receipt of irb clearance for future surveys and data collection. in addition to cleaning up and refining these assessment practices, this will also provide the opportunity to publish and present publicly on more specific data. ideally, the group will be able to correlate the show’s presence to positive citation or metrics levels with show participants. the usf libraries geosciences rpt is currently collecting baseline aggregate information, which could then be compared following further maturation and dissemination of the podcast. causality may never be within reach, but any positive impacts will be exciting and beneficial. it is also the hope of those involved with calling: earth that it might provide a model or template for other rpt or library podcasts or media efforts. one of the current benefits is the strong and effective support from the development and communication directors at the usf libraries and their partnerships in the future will certainly be key to the success of this and any other potential projects of this type. in

investigate the activity of iranian scholars in the medical sciences in researchgate and to explore the effect of each of the four researchgate metrics on the rg score. moreover, the citation metrics of the faculty members in scopus and the relationship between these metrics and the rg score were explored. methods: the study population included all sbmu faculty members who have profiles in researchgate (n=950). the data were collected through researchgate and scopus in january 2021. the spearman correlation coefficient was applied to examine the relationship between researchgate metrics and scopus indicators as well as to determine the effect of each researchgate metric on the rg score. results: the findings revealed that the publication sharing metric had the highest correlation (0.918) with the rg score and had the greatest impact on it (p-value <0.001), while the question asking metric showed the lowest correlation (0.11). moreover, there was a significant relationship between the rg score and scopus citation metrics (p-value <0.05). furthermore, all four rg metrics had a positive and significant relationship with scopus indicators (p-value <0.05), in which the number of shared publications had the highest correlation compared to other rg metrics. conclusion: researchers’ participation in the researchgate social network is effective in increasing citation indicators. therefore, more activity in the researchgate social network may have favorable results in improving universities’ ranking. introduction conducting any scientific activity first requires gaining knowledge of previous relevant research and citing those sources. there is often a content link between these activities and the sources cited.1 typically, receiving citations is essential and valuable for researchers because, on the one hand, this issue is effective in the career advancement and promotion of researchers and, on the mailto:saeideh.valizadeh@gmail.com mailto:nasibi.lib@gmail.com mailto:shekofteh_m@yahoo.com mailto:shahab.rahmatizadeh@gmail.com information technology and libraries march 2022 researchgate metrics’ behavior | valizadeh-haghi, nasibi-sis, shekofteh, and rahmatizadeh 2 other hand, researchers intend to have a greater impact on science by receiving more citations. these works should be shared with other researchers and exposed to their observation to increase scholars’ research activities’ citation rate using appropriate tools.2 in this respect, academic social network sites are appropriate tools for sharing and exposing scientific works to increase citation rates.3 academic social network sites have brought researchers together regardless of time and space constraints and have facilitated scientific communication and information exchange.4 in addition, researchers can use these networks to pursue their common interests with other users.5 various studies indicate that sharing publications and subsequently publications’ visibility through social networks increases the citation rate of these works by more than 50%. it has also been observed that journal articles which are shared through these networks have received more citations than other articles in the same journals.6 one academic social network site for the exchange of scientific information is researchgate, which authors can use to cooperate with researchers in all scientific disciplines.7 through this network, researchers‘ scientific works will have better visibility by other people.8 to use this network, users must initially create their profile and then perform scientific activities.9 the researchers’ activity level in this network is indicated by the rg score, which is determined based on four individual metrics, including the number of shared publications, the researcher’s activity in asking questions, the researcher’s activity in answering other people’s questions, and the number of followers. the individual rg metrics affect researchers’ rg score, but the extent of individual metrics impact on this score is not clear.10 shahid beheshti university of medical sciences (sbmu) is one of the top universities in iran. according to the evaluation of medical universities’ research activities in the webometrics ranking of world universities, sbmu has achieved the fourth rank among iran’s medical universities.11 in the centre for science and technology studies (cwts) leiden ranking, this university is ranked 11th among iranian universities and 646th among world universities.12 faculty members are one of the main components in universities’ educational structure and play a crucial role in generating, conducting, and disseminating knowledge. due to the importance of citations of faculty members’ scientific works in ranking systems and the situation of sbmu in world rankings, it seems that measures should be taken to improve the citations of faculty members of this university as one of the ways to improve the ranking of the university. considering that more than half of the published articles never receive citations, as well as the positive role of research sharing on social networks in increasing the number of citations, it seems that the activities of sbmu faculty members in the researchgate network may increase the citations count to their research and, consequently, improve the university’s ranking.13 however, to date, no research has been carried out on the activity of the faculty members of sbmu in researchgate. literature review various studies have addressed researchers’ activity in the researchgate academic network. the level of researchers’ activities in researchgate and the relationship between citation metrics and rg score are among the topics that have been investigated. information technology and libraries march 2022 researchgate metrics’ behavior | valizadeh-haghi, nasibi-sis, shekofteh, and rahmatizadeh 3 regarding researchers’ activity in researchgate, numerous studies have been carried out. among these, the research of nikkar, rahmani, lui, sheeja, muhammad yousuf ali, mahajan, and joshi can be mentioned.14 nikkar et al. conducted a study to investigate surgical researchers’ activities in researchgate, which revealed that the majority of these researchers (86.24%) are active members in researchgate.15 rahmani et al. identified the activity of faculty members of technical colleges in researchgate, which showed that most of these researchers (64.16%) were active members of this network.16 the study by sheeja et al. of naval architecture engineering researchers at researchgate revealed that most of them (65%) have a researchgate profile.17 the study by muhammad yousuf ali, titled “altmetrics of pakistani library and information science researchers at researchgate,” indicated that 75.73% of researchers have a researchgate profile.18 in contrast, in studies conducted by mahajan et al., joshi et al., and lui et al., findings showed that less than half of the surveyed researchers are active users of this network.19 in addition to measuring activity in researchgate, some other studies also examined the relationship between the rg score and citation indicators. in this regard, in a study by joshi et al., it was revealed that there is a significant relationship between the rg score and citation metrics.20 shrivastava et al. also conducted an analysis of researchgate profiles of panjab university lecturers.21 the results demonstrated that there is a significant relationship between rg and citation metrics. a study conducted by naderbeigi et al. showed that there is a significant relationship between activity on the researchgate network, rg score, and scopus metrics of the faculty members of sharif university of technology.22 the allied medical science scientists’ activity in researchgate was examined by valizadeh-haghi et al.23 the study revealed that there is a significant relationship between rg scores and scopus indicators. correspondingly, the findings showed that there is a significant relationship between lecturers’ academic ranking and their rg scores as well as scopus indicators. according to the literature, it seems that the effect of each of the individual metrics of researchgate on the rg score has not so far been studied. researchgate also has not officially specified the impact of any of its individual metrics on the rg score, while researchers’ awareness of this impact may affect their activity behavior in any of the individual metrics to increase their rg score. previous studies also show that limited research has been conducted in iran regarding faculty members’ activity in researchgate. accordingly, none of these studies has investigated the activity of all faculties of a university. therefore, the objectives of the present study include (1) investigating the activity of sbmu faculty members in researchgate, (2) investigating the effect of each of the four individual researchgate metrics on the rg score of the faculty members, (3) determining the citation metrics of the faculty members in scopus, and (4) the relationship between individual rg metrics and the faculty members’ scopus citation metrics. material and methods the present altmetrics study population included all sbmu faculty members who have profiles in researchgate (n=950). information technology and libraries march 2022 researchgate metrics’ behavior | valizadeh-haghi, nasibi-sis, shekofteh, and rahmatizadeh 4 to extract the number as well as the name of the faculty members, we used the iranian scientometrics information database, which is developed by the deputy of research and technology of ministry of health and medical education of iran.24 the number of faculty members in this system was 1,430, of which 950 had profiles in researchgate and were examined. the data regarding rg score were collected through direct observation of their profiles in researchgate. the rg score includes four metrics: number of shared publications, researcher’s activity in asking questions, researcher’s activity in answering other people’s questions, and followers. data related to the number of citations and the h-index of each of the lecturers were collected by viewing their profiles in the scopus database in january 2021. in this study, it was assumed that there is a significant relationship between researchgate individual metrics and scopus citation metrics. given that the data were not normally distributed, to examine this relationship, the spearman correlation coefficient was used. moreover, regarding that the impact of each of the researchgate metrics on the rg score has not been officially determined, the spearman correlation coefficient was applied to determine the effect of the individual metrics of researchgate on the rg score of the participants. the collected data were analyzed using excel and spss version 18 software. results the rg score of the faculty members is shown in table 1. all faculty members had an rg score, and most of the faculty members (79.5%) had an rg score of less than one. the average rg score of participants

compared the rg metrics of sbmu faculty members. the major findings are highlighted and discussed around the four research questions of this study. the findings of the present study revealed that even though more than half of the faculty members have profiles in researchgate and are active in this network, compared to the findings of other studies, such as those of yousuf ali, janmohammadi, rahmani and nikkar, this rate is low.25 this issue may be due to the lack of knowledge and familiarity of faculty members with the researchgate social network or the lack of the need to publish outputs on the researchgate social network, which needs further investigation. the present study results also showed that the mean rg score of sbmu faculty members is similar to the results of other studies conducted in iran and other international studies.26 the current study results indicated that the subjects’ activity in the four rg metrics was slight in some indicators, and the highest activity was related to publications metric. the lowest level of members’ activity was related to the asking-questions metric. considering that the rg score results from the scores obtained by the researcher in the four rg metrics, this study’s research results confirm that the faculty members did not pay enough attention to the activity in all the rg metrics. the present findings showed that faculty members have limited activities in sharing publications, which is aligned with the results from other studies.27 this could be due to several reasons. firstly, young faculty members who have recently joined the university as faculty members may have fewer publications in comparison with older members. another reason may be that faculty members who have recently joined the researchgate social network have not had enough time to share all of their publications. it should be noted that sharing publications on researchgate has massive ramifications for the open access movement. it might be that one of the reasons authors do not publish on rg is because they do not have the rights to do so. in this regard, it is worthy to mention that the publication-sharing metric includes both full-text sharing and/or abstract information technology and libraries march 2022 researchgate metrics’ behavior | valizadeh-haghi, nasibi-sis, shekofteh, and rahmatizadeh 9 sharing in which sharing the abstract is legal. so, researchers were free to share their abstracts but they have not done it. the findings also show that most of the sbmu faculty members have no activity in two metrics: asking questions and answering questions. compared to other studies, the activity of sbmu faculty members in these metrics is at a lower level.28 possible reasons for this could be a lack of awareness of the importance of these metrics to increase the rg score, a lack of english language proficiency to participate in asking and answering questions, and a lack of time. however, more research is needed in this area. the results showed that most of the sbmu faculty members have followers. the mean number of followers of the faculty members is similar to what was found in other studies.29 as the number of followers increases, a person’s popularity in their subject area increases. they may even be influenced by the researcher’s studies in other areas and follow the researcher’s activities in researchgate and, with the increase of followers, there is a possibility of increasing the citation rate.30 therefore, it is recommended to elaborate on the importance and role of each of the rg metrics in raising the rg score through posters, workshops, and educational brochures for faculty members. in this study, the correlation between each of the rg metrics and rg score was examined using the spearman correlation test. the present study results revealed that the shared publication and number of followers metrics have a stronger correlation with the rg score compared to the metrics of questions and answers. the results also showed a significant correlation between all rg metrics and the rg score of sbmu faculty members. the study results indicated that most of the sbmu faculty members have citations in the scopus database and have an h-index, but most of them received the least number of citations. according to the present study findings, the subjects have little activity in the researchgate social network. as one of the possible reasons for the low number of citations, we can mention the low activity in the researchgate social network. research on surgeons’ publications has also confirmed this.31 nevertheless, there is a need for further research on the low number of citations of faculty members of sbmu. the present study’s findings demonstrated a significant relationship between the rg score and scopus citation metrics (h-index and number of citations). in this regard, the highest correlation was observed between the h-index and rg score (p-value = 0.803). this finding is consistent with other studies’ findings.32 there is also a significant relationship between each of the rg score metrics and scopus citation metrics. in this regard, the highest and lowest correlations with scopus citation metrics were observed between publication, questions, and answers metrics, respectively (p-value = 0.001). considering the positive relationship between each of the rg metrics and scopus citation metrics, it is suggested that faculty members pay enough attention to all of these metrics to help increase their citation indicators. due to the researchgate social network’s role in increasing the visibility of researchers’ scientific outputs, faculty members can consider the use of this network as one of the tools to increase the number of citations and the h-index. conclusion easy access to research outputs and increasing visibility is one of the most important features of researchgate, which, according to the results of this study, has a significant impact on increasing information technology and libraries march 2022 researchgate metrics’ behavior | valizadeh-haghi, nasibi-sis, shekofteh, and rahmatizadeh 10 the use and thus increasing citations. as the results revealed, researchers’ participation in the researchgate social network is effective in increasing citation indicators, including the number of citations and h-index. therefore, more activity in the researchgate social network, followed by receiving citations, can have favorable results in improving rankings for both research institutes and universities. universities can encourage faculty members to join and work in researchgate and other academic-social networks by considering privileges to improve their academic rank. libraries and research centers can explain the importance of faculty members’ activities in these networks by holding workshops on altmetric indicators and academic social network sites, especially researchgate. they can also justify to researchers the benefits of using this network and sharing more scientific outputs. declaration of interest: none funding: this work was supported by the school of allied medical sciences,

column layout column title 44 information technology and libraries | september 2008 communications james feher and tyler sondag administering an open-source wireless network this tutorial presents enhancements to an open-source wireless network discussed in the june 2007 issue of ital that should reduce its administrative burden. in addition, it will demonstrate an opensource monitoring script written for the wireless network. as it has become increasingly important to provide wireless internet access for their patrons, libraries and colleges are almost expected to offer this service. inexpensive methods of providing wireless access—such as adding a commodity wireless access point to an existing network—can suffer from security issues, access by external entities, and bandwidth abuses. designs that address these issues often involve more costly proprietary hardware as well as expertise and effort that are often not readily available. a wireless network built with open-source software and commodity hardware that addressed the cost, security, and equal access issues mentioned above was presented in the june 2007 issue of ital.1 this tutorial highlights enhancements to the previous design that help to explain the technical hurdles in implementation, and includes a program that monitors the status of the various software and hardware components, helping to reduce the time required to administer the network. the wireless network presented requires several different pieces of software that must work together. because each of the required software programs are frequently updated, slight changes to the implementation may also be needed. a few issues that have arisen since the previous paper was written are addressed. a note is provided explaining the significance of setting the correct media access control (mac) address for the radius server and for wireless distribution system (wds) when configuring the system. in addition, in order to provide secure exchange of authentication credentials (username and password), the secure socket layer was used. a brief explanation of how to install a registered certificate on the gateway server is provided. lastly, a program that monitors the status of the network, provides a web page displaying the status of the various hardware and software components, and e-mails administrators with any changes to the network status—along with information on how this program is to be deployed within the network—is presented. configuration changes for previous design as new exploits are discovered and patched on a continual basis, any system should be regularly updated to insure that the most recent software is being used. the network design provided in the previous article used many different software components including, but not limited to: access point software openwrt—whiterussian rc3 dns cache dnsmasq v2.32 gateway chillispot v1.0 operating system fedora core 4 radius server free radius v1.0.4 web caching server squid v2.5 web server apache 2.2.3 many of these components can be kept up-to-date by using the yellow dog updater, modified (yum). 2 for example, to update a given package, with root access, at the command line enter: yum update packagename the yum command may also be used to update each package that has an available update by simply removing the package name from the yum update command and entering the following: yum update yum may also be used to upgrade the entire operating system.3 keep in mind that with any change in software, the configuration of any particular package may change as well. for example, the newest version of squid is currently 2.6. appendix d in the previous paper explained how to allow transparent relay of web requests so that client browsers did not have to be reconfigured. so, while version 2.5 required four changes to allow the transparent relay, the current version—found in appendix a—requires only one. in addition to changes in software, occasionally even entire websites move, as happened with chillispot.4 another change involved the configuration of the linksys wrt54gs access points. the newer versions of this access point/router sold by linksys have half the flash memory and half of the ram of the older versions.5 while the newer versions of the linksys wrt54gs can be flashed with custom firmware,6 the firmware that will fit on the newer unit lacks all the capability of the standard firmware. given this, those wishing to implement such a wireless network should investigate the capability of models to be deployed, as well as the version numbers for the access points chosen. the current version of the linksys wrt54gl and wrtsl54gs units retain enough flash memory and ram to be updated with the standard firmware mentioned in the previous article.7 james feher (jdfeher@mckendree.edu) is associate professor of computer science and computer information systems at mckendree university, lebanon, illinois. tyler sondag (sondag@cs.iastate.edu) is a phd candidate in computer science at iowa state university, ames. introducing zoomify image | smith 45administering an open-source wireless network | feher and sondag 45 in addition, the procedure for upgrading the firmware for the wrtsl54gs is simpler than the procedure outlined in appendix i of the previous paper. the factory-installed firmware on version 1.1 can be flashed directly using the web interface provided by linksys. so, while this tutorial and the previous paper outline the design of a network, the administrator will need to be vigilant in updating the packages used and keep in mind that the configuration specifications may also change with those updates. the administrator for the network must also investigate the capability of the standard hardware used to insure that it retains the functionality required for the system. choosing the correct mac address for the access point the access points used will have more than one interface and as such more than one mac address. when entering the mac address of a given access point into either the users file for the radius server or the access points that use the wds, use the mac address associated with the wireless interface.8 using the incorrect mac address will result in problems when communicating with the various access points. for the radius server, the access point will not get the correct ip address, which will prohibit the possibility of remotely administering the unit. incorrect mac addresses that are used for the wds settings will cause even worse problems, as the unit will not be able to relay data from users who connect to this access point. installation of a registered ssl certificate as users are required to enter their authentication credentials to gain access to the internet, the exchange of this data is encrypted using the secure socket layer.9 while administrators can self-sign the certificates used for their web servers, it is recommended that a registered certificate be obtained and installed for the system. this can help prevent common attacks and has the added benefit of eliminating warnings for the client browsers when they detect unregistered certificates being used by the ssl. a search of “ssl certificate” will yield any number of commercial vendors from which a certificate can be obtained. generally the installation of a certificate is fairly straightforward. the openssl command line utility can be used to generate a ssl key and certificate signing request (csr).10 once the csr is generated, pick a vendor/certificate authority who can sign your key. it should be noted that the design presented required the authentication gateway to be behind the main router. this required a certificate to be signed for a server within an intranet that does not have a fully qualified domain name. so, when generating the ssl key and csr, make sure to use gatewayhostname.localnet as the common name of your server. of course, gatewayhostname is whatever you choose as the name of your gateway host. the term localnet is used to refer to the server existing within an intranet. then make sure to place an entry for gatewayhostname.localnet into the hosts file of the server that is providing domain name service for your network. an example entry for the hosts file which is in the /etc directory of a standard fedora core installation is found in appendix b. monitoring script for wireless network as the wireless network has many separate hardware and software components, many possible points of failure exist for the system. the script from appendix c, which was written in perl,11 uses ping to test if each access point is still connected to the network and nmap to test whether the port associated with a given network service is still available.12 this program can be run manually or, even better, run automatically through the unix cron utility to update a webpage that displays the current state of all the network components. the webpage generated by this script for the mckendree college wireless network may be found at http://lance.mckendree.edu/cgi-bin/wireless/status.cgi. (additionally, a sample of this page is available as a figure in appendix d.) this script actually contains a script within a script. the main script must be run on the gateway machine, chilli on the diagram in appendix e, as only this machine has access to ping the access points. when the script determines that an access point or daemon is down, it will e-mail the system administrator. when an access point is down, in addition to sending the system administrator an e-mail, it can also send notification to an e-mail address associated with that device. this allows for someone other than the system administrator—who may have closer physical access to the unit—to check the access point on behalf of the administrators for simple issues, such as an access point losing power. this script then generates another cgi script that can be transmitted to an external server that can be reached from anywhere on the internet. in this case, this generated script can be run as a web-based application or by the system itself using the cron utility. if run as by the cron daemon, it will also e-mail the administrators if the script has not been updated recently. the script requires the use of several perl modules that will need to be installed. n expect n mail::mailer n net::ping the script has been released using the gnu general public license, 46 information technology and libraries | june 200846 information technology and libraries | september 2008 version 2 (gpl).13 the first portion of the script contains a reference to the gpl, followed by a brief explanation of the script as well as a set of parameters that should be changed to fit the specifications of the network designed. conclusion administrators should be vigilant in updating the entire system to assure security, keeping in mind that new versions of software or hardware may necessitate changes in the overall configuration of the system. in addition, while the monitoring script provides a useful aid in monitoring the network, it could be further expanded to include a more comprehensive review of level of use for various access points by the different users. it is felt that this would be best done through a database, which would require a higher level of administrative effort. a brief frequently asked questions list along with the script and link to the code for the script can be found at http://lance.mckendree.edu/csi/ wirelessfaq.html. references 1. sondag, tyler and james feher, “open source wifi hotspot implementation,” information technology and libraries 26, no. 2: 35–43, http://ala.org/ala/lita/ litapublications/ital/262007/2602jun/ toc.cfm (accessed july 24, 2008). 2. linux@duke, “yum: yellow dog updater, modified,” http://linux.duke .edu/projects/yum (accessed july 24, 2008) 3. upgrading fedora using yum frequently asked questions, http://fedora p r o j e c t . o r g / w i k i / yu m u p g r a d e f a q (accessed mar. 16, 2007). 4. chillispot—open source wireless lan access point controller, “spice up your hotspot with chilli,” www .chillispot.info/ (accessed may 22, 2008). 5. openwrtdocs/hardware/linksys /wrt54gs—openwrt, http://wiki.open wrt.org/openwrtdocs/hardware/link sys/wrt54gs (accessed july 24, 2008). 6. bitsum technologies wiki— wrt54g5 cfe, http://bitsum.com/ openwiking/owbase/ow.asp?wrt54g5_ cfe (accessed july 24, 2008). 7. openwrtdocs/hardware/linksys/wrtsl54gs—openwrt, http:// wiki.openwrt.org/openwrtdocs/hard ware/linksys/wrtsl54gs (accessed july 24, 2008). 8. o p e n wr t d o c s / w h i t e r u s s i a n / configuration, wireless distribution system (wds)/repeater/bridge. http:// wiki.openwrt.org/openwrtdocs/white russian/configuration (accessed july 24, 2008). 9. viega, john, matt messier, and pravir chandra, network security with openssl cryptography for secure communications.

abstract in 2020, during the covid-19 pandemic, colleges and universities around the world were forced to close or move to online instruction. many institutions host yearly student research symposiums. this article describes how two universities used their institutional repositories to adapt their student research symposiums to virtual events in a matter of weeks. both universities use the bepress digital commons platform for their institutional repositories. even though the two universities’ symposium strategies differed, some commonalities emerged, particularly with regard to learning the best practices to highlight student work and support their universities’ efforts to host research symposiums virtually. introduction many colleges and universities host student research symposiums as a way to celebrate students’ intellectual experiences and support the high-impact practice of presenting original student research. students contribute research outputs and share their projects with others in their institution’s community, beyond the classroom. typically, many of these student research symposiums are conducted in the second half of the spring semester in order to allow students to work on their research throughout the course of the year. during the 2020 school year, the world experienced the covid-19 pandemic. the many ways this pandemic has changed our society are only now being understood, but the pervasive move to virtual meetings and presentations is certainly one of the most dramatic. college campuses began delivering remote instruction in a matter of days and organizers of student research symposiums around the country were forced either to cancel or reimagine the events. longwood university and university of south florida st. petersburg campus (usf) were two institutions that transformed their in-person student symposiums into online events in a matter of weeks. in this article, the authors share their experiences of working with many people throughout their campuses to create a student research symposium experience similar to their past in-person events. both universities use bepress’ digital commons platform for their institutional repositories. overall, longwood’s and usf’s symposium strategies were different in some regards, but some commonalities emerged, particularly with regard to learning the best practices that celebrate the students’ achievements and support their universities’ efforts promoting high-impact student research. literature review student research has grown in importance. following george kuh’s 2008 report, high-impact educational practices: what they are, who has access to them, and why they matter, universities recognized and responded to the need to integrate these high-impact practices into their curricular and co-curricular efforts.1 one of the recognized high-impact practices is student mailto:asymulev@usf.edu mailto:hamiltonma@longwood.edu information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 2 research.2 students can contribute to their disciplinary scholarly conversation through their original research and by presenting on their research projects, and colleges and universities can promote this conversation by facilitating the display of student work and enabling interactive discussions between the student presenters and other members of their academic community. the number of student research conferences has increased internationally. 3 students participate in the formal aspect of these conferences, as well as informal conversations where they can continue to expound on their research, extend their professional social networks, and gain confidence as researchers.4 student research is also being captured in institutional repositories (irs) more than in the past.5 “these most junior members of the academic community are doing research and adding to the body of knowledge generated by their institutions and in their disciplines.”6 passehl-stoddart and monge point out the importance of institutional repositories supporting student work: “the ir also serves to support, enhance, and capture evidence of high-impact educational practices; acts as an equitable access point to meaningful learning opportunities; and provides a platform for students to begin to develop academic confidence and an entryway into the scholarly communication learning cycle.”7 in supporting high-impact student research, librarians do not act alone. we collaborate with other departments on campus such as offices of undergraduate and graduate studies; offices of research, honor colleges, student affairs; and more. krause, eickholt, and otto describe how the library collaborated with the music department at eastern washington university to upload student musical performances to the institutional repository.8 this type of collaboration leads to increased student support, as well as increased discoverability of student intellectual and creative scholarship. when the covid-19 pandemic hit, universities around the world were forced to change their means of conducting business. classes were moved online at many institutions. conferences were either canceled or moved online as well. many colleges and universities around the coun try host student research symposiums to highlight the high-impact work that students are doing. these symposiums needed to move to remote delivery, and many of these had to move quickly as the spring semester was well underway when institutions were being forced to close. symposiums and conferences adapted to online environments by moving away from their inperson events. this applied to both academic and professional conferences. for example, oregon state university (osu) and the new haven local section of the american chemical society hosted their respective events virtually using a variety of technologies. osu worked with its distance learning unit to create a canvas course, whereas the new haven local section of the american chemical society used a combination of open broadcaster software (obs studio), youtube, zoom, and google drive. as far as professional conferences, many used prerecorded sessions when hosting on digital platforms such as zoom.9 there were positive outcomes from these virtual symposiums. for example, osu saw benefits of “enhanced ability to devote personalized attention to presenters (e.g., by providing links to relevant publications or websites), fewer distractions, more time to craft thoughtful responses, and an ability for students to keep track of shared resources and discussants’ contact information that could be used for follow-up after the event.” their post-event surveys also showed that students who could not previously participate due to distance circumstances were able to information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 3 participate in an online forum. osu’s approach involved using canvas, their learning management system (lms), through which students submitted prerecorded lightning talks over powerpoint slides with a written narrative. the canvas course was open to the osu community. discussion boards for commenting were open for a two-day period.10 in her article, stephanie houston interviewed various conference coordinators.11 interviewees stated that a major benefit was global access to information from top researchers.12 with regard to cancer research conferences, free registration vastly expanded the number of registrants from previous years.13 conference hosts felt as though some of the differences of online events would stay for future years because of personal scheduling issues, ability to provide global access, and environmental impact.14 others think the novelty of virtual events may wear off following the pandemic.15 however, the switch to virtual events was not without challenges. osu noted that two main challenges they faced were organization of presentations and presenters responding to comments on their asynchronous presentations.16 houston’s interviewees explain that the lack of informal discussions and face-to-face interactions was a negative of hosting virtual symposiums.17 speirs also states that virtual poster sessions suffer from the lack of interaction of face-to-face exchanges, especially for young researchers.18 some saw that the large number of participants made it difficult for participants to engage in question-and-answer sessions.19 two of the interviewees attempted to fix this by using twitter to have asynchronous q&a using a specific hashtag for the event.20 technology issues such as limited bandwidth and internet connectivity problems are a concern for virtual conferences.21 conferences that are not archived can result in a loss of material beyond the original event. jonathan bull and stephanie davis-kahl discuss the problem of conference ephemera not being accessible in their poster presentation.22 they explain that conference-hosting as an institutional repository service can assist with this lack of accessibility. “by posting documents and artifacts from conferences within an institutional repository, the content is not only accessible for future use, but also preserves those materials for the future and for institutional memory.”23 virtual student research symposiums longwood university’s virtual spring showcase for research and creative inquiry longwood university is a public university in south central virginia. it has about 4,000 undergraduate and 500 graduate students. it is known for its liberal arts focus, with strong programs in the humanities, nursing, and education. since spring of 2018 there has been a spring symposium of undergraduate research (now called the spring showcase for research and creative inquiry). for the first three years of its existence, the spring showcase was planned as a single day event in april, then a fall showcase was added in november 2019. in january 2020, the university showcase committee began planning to have an in-person spring showcase for research and creative inquiry on april 22, 2020. the proposed schedule was to be as follows: students would register to be part of it by march 13, 2020; they would be notified of their acceptance by the end of march, and they would be encouraged to submit posters to the institutional repository, digital commons @ longwood, by the date of the spring showcase, april 22. planning for the in-person showcase continued throughout february and the first part of march. one of the elements on the registration form was giving permission for student content to information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 4 go into the institutional repository. this step had been added in fall 2019 for the previous showcase. as covid-19 cases in the united states began rising in the beginning of march, administrators at longwood began to discuss the possibility of altering certain events. author mark hamilton considered the possibility of offering the institutional repository as a vehicle for hosting digital content for the showcase. by march 23, the director of undergraduate research notified the author that a decision had been made to host the spring showcase as an asynchronous event from april 22–24, 2020. this decision had been made by a small group including the co-chairs of the showcase and the provost in consultation with others. the director of undergraduate research specifically asked the library if the event could be hosted virtually through digital commons @ longwood and also requested a comments feature to facilitate online conversation. students, faculty, and staff would comment on the presentations throughout the three-day showcase. presenters would check the comments within those three days and post replies. the director also asked if it would be possible to upload videos that could go along with posters and other presentations. hamilton and the library’s digital initiatives specialist began to work through the technical aspects of making the showcase virtual. after inquiring about potential software from digital commons, they looked through two suggested options, disqus (https://disqus.com/) and intense debate (https://intensedebate.com/). they decided on intense debate because the comments feature was already integrated into the platform. they also looked through the various video formats available. then they worked with the digital commons representative to develop the structure for the showcase. this involved a bit of dialogue back and forth between the showcase co-chairs, digital commons staff, and the library. because the registration form already gave permission to post student content, it was decided that the university did not need to ask for this permission a second time for a virtual conference. new workflows were developed for the research submission process which included posters, presentations, and videos. faculty would submit files on behalf of students in their classes. library staff and instructional designers developed video and printed upload instructions. they were posted on the showcase website (part of the university website) as well as advertised via the library website. faculty asked students to submit their final projects by thursday, april 16, so there was time to upload the project posters and videos to digital commons @ longwood. most students submitted their projects through the campus lms, canvas. as faculty attempted to upload content, library staff were available to help them. the author helped one faculty member via zoom, describing the process of uploading to digital commons. one process that had to be adjusted involved powerpoint presentations that contained videos—they had to be separately downloaded and then just the powerpoint of the poster re-uploaded, so visitors could both view the powerpoint and watch the video. hamilton and the other staff member worked with faculty to place all the required content for each presentation; then the library’s digital initiatives specialist made all the content live. a number of activities occurred during the showcase. initially the digital initiatives specialist individually approved the comments that were posted, because this was the default set up. later this was changed to allow for automatic posting to speed up the approval process and to remove any apparent bias on the part of the administrators. some faculty also uploaded a few new versions of presentations. some of the science students decided to post only their abstracts, https://disqus.com/ https://intensedebate.com/ information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 5 because they were going to publish their research in journals and did not want their content to be open access and because some faculty were co-authors in these publications. in the subject listing, library staff included a link to the live zoom presentations that were offered. there was also a link to a live zoom session for the showcase awards ceremony, highlighting submissions to the journal of the college of arts and sciences. longwood university has hosted two more virtual showcases: in fall 2020 and spring 2021. the showcase organizers chose to switch the hosting platform to symposium by forager one (https://symposium.foragerone.com/), a third-party platform that allows for virtual and live posting of presentations and videos. the new platform provided an easier interface for students to submit research and administrators to manage it. library staff worked with the showcase organizing committee to preserve all the abstracts from the spring showcase. they are in discussions with how future content will be preserved and whether library staff should collect some of the research into the institutional repository. university of south florida st. petersburg campus virtual student research symposium the university of south florida st. petersburg campus is a branch campus of the larger university of south florida (usf). usf is an r1 research institution with approximately 50,000 undergraduate and graduate students in tampa, florida. at the time of the 2020 virtual student research symposium, usf st. petersburg campus was a separately accredited institution with roughly 5,000 undergraduate and graduate students. the student research symposium was in its 17th iteration in 2020. the office of research at usf st. petersburg organized the event and coordinated with the nelson poynter memorial library and the honors program. undergraduate and graduate students were invited to share their work with the campus community to demonstrate the high-impact research that they were conducting. in 2019, the library had worked with the office of research to host award winners and posters nominated by faculty on the bepress digital commons institutional repository called usfsp digital archive. for the 2020 symposium, the office of research began planning in august 2019. the inperson symposium was scheduled for april 16, 2020. when the covid-19 pandemic hit, the usf st. petersburg campus moved to remote instruction and ended on-campus activities on march 20, 2020. the office of research staff contacted librarians at nelson poynter memorial library to discuss the possibility of a virtual symposium. author allison symulevich considered a variety of platforms for hosting the research symposium, such as the campus website, canvas, libguides, digital commons, and facebook. criteria for platforms included factors related to team control, security, engagement, and archiving. becaus e of these factors and the prior pilot project, the library decided to recommend that the institutional repository be used to host the virtual research symposium. the office of research wanted to capture an experience for the students similar to that of the inperson event. thus, they requested that the platform include both video and audio options, as well as a way for the poster to be viewed. the office of research also requested audience participation through a commenting feature if possible. they also extended student submission deadlines to assist with the disruption in students’ lives. the office of research used a course in canvas, the learning management system used at usf, to collect research posters and presentations from the students. the library digital team was given https://symposium.foragerone.com/' information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 6 access to the canvas course so that the team could download posters, presentations, and abstracts to then upload to the institutional repository. the library uploaded 55 student projects, 43 of which had a video or audio presentation. the digital team had hoped to batch upload the files to the institutional repository using spreadsheets containing metadata such as author names, titles, abstracts, and links to audio or video presentation files. however, due to technical concerns, everything was uploaded manually, with work divided amongst team members who had previously used the system. first, all of the content was downloaded from canvas. these files were then posted to a shared drive in a variety of folders organized to maintain a workflow. the projects with audio/video presentations were uploaded first. then the projects that had abstracts and posters were added. due to time constraints, the digital team wanted to make sure the basics were done first so students would have time to make any revisions necessary before the site was promoted to the usf st. petersburg community. after this initial implementation, the team had a meeting with the larger committee to discuss the progress of the digital collection. the committee suggested some changes and offered constructive feedback. once the abstracts, posters, and presentations (either audio or video) were posted, the team noticed issues with some submissions. some students had submitted powerpoint presentations that did not display as the team was hoping, so one of the team members changed the format to mp4 files. audio files did not include a visual component. as a way to add a visual component, the team worked with digital commons to create a digital image gallery and add thumbnail images that could then be added to a special metadata field called poster preview. this enabled the collection to have a visual of the poster displayed above the audio file, allowing virtual attendees to press play on the audio file and see the poster image on the same page. the team then turned to the office of research’s request for a feature that allowed virtual attendees to interact with student presenters. digital commons does not have a commenting feature, so the digital team had to look at third-party commenting platforms. digital commons was able to integrate the platform chosen, intense debate, so that virtual attendees could comment on presentations. students were asked to monitor their posters for a two-week period. moving forward, the library and the usf st. petersburg campus discussed using the institutional repository for the spring 2021 symposium. however, due to administrative consolidation of the usf tampa, st. petersburg, and sarasota-manatee campuses into a oneusf with a single accreditation, the new combined office of research on the tampa campus decided to host the newly expanded, one-university, undergraduate student symposium through a canvas course.24 download statistics following the research symposiums, the authors looked at metrics for the virtual events. at usf, 55 presentations were uploaded to the ir. all time downloads from april 1, 2020 to december 31, 2021, including additional supplementary files, is 2,068, from 53 countries around the world. total streams of audio or video presentations for the same timeframe are 1,168. at longwood, 200 presentations were uploaded to the ir. all time downloads from april 13, 2020 to december 31, 2021, including additional supplementary files, is 16,190 from 124 countries around the world. total streams of video presentations for the same timeframe are 2,541. see figures 1 and 2. these presentations are still getting downloads and streams—one of the benefits of preserving high-impact student research projects. information technology and libraries march 2022 using open access

libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 8 best practices after reflecting on these large undertakings to move in-person events to online student research symposiums, the authors have identified some common best practices, meant to assist other institutions making similar decisions. these decisions are based on the following core requisites. consistent university branding although both universities used bepress’ digital commons platform, institutions can use a variety of online platforms, such as campus websites, other institutional repositories, and third-party software for conference hosting, such as symposium by forager one or lumen learning. use a system that creates a cohesive look and feel to the collection of student research projects. usf had to do this with audio only presentations for consistency of viewing, adding a visual co mponent to match those of video presentations. university access or open access use a platform that allows archiving of student projects. even if the platform chosen for hosting the event does not allow for archiving, libraries should work with event hosts to provide institutional repository digital archiving of projects, similar to usf’s pilot project and longwood’s 2021 spring project of archiving abstracts. libraries can offer this as a solution to provide permanent archiving of high-impact student work.25 institutions need to consider whether they will keep their symposiums closed, meaning only accessible to the university community, or open to the world. while it is technically straightforward to restrict access using the campus lms, irs using net id sign-ins, or private websites, the authors argue for worldwide access to these presentations. archiving student work archiving these projects allows students to build their cvs for graduate school or interviews by providing hyperlinked citations to worldwide published projects. making these projects available open access allows students to contribute to the worldwide scholarly conversation on their given research topics.26 statistics from both longwood and usf show international downloads. file formats as far as file formats that work best, consider embedding video and audio files using consistent formats. mp4 video files worked best for both longwood and usf on the digital commons platform. audio files should be consistent as well for preservation. cross-unit collaborations work with other departments on campus to host these major academic events. many units on campus contribute to student success, and these efforts can be combined to distribute work amongst university faculty and staff so as not to overload one department and to provide the best possible symposium. different departments have different skill sets, such as technology and marketing. both longwood and usf st. petersburg libraries worked with departments such as undergraduate studies and communications to switch these in-person events to successful online programs. consider working with distance learning units to increase distance learning student participation in student research symposiums.27 distance learning and it departments may have additional technology experience that could lead to a better overall experience for students. in 2021, longwood worked with the office of student research, the library, marketing and communications, and academic affairs to put on the spring student showcase. this inter-unit information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 9 work led to another successful online event, with several hundred student researchers presenting their work. flexibility institutions should use flexible workflows when transitioning in-person events to online. both longwood and usf used flexible workflows for posting presentations into institutional repositories. however, the two universities differed in their submission process. longwood had faculty submit student projects directly to the ir, a more distributed approach. usf st. petersburg had students submit projects to canvas and then the digital team posted projects to the ir, a more centralized approach. institutions will need to decide which approach works best for them. usf st. petersburg does not have a history of allowing outside submissions to its ir. the digital teams needed to remain flexible as event dates were moving and online technology requests were changing, for example, event coordinators requesting online commenting features. similarly, deadlines should be set with realistic timeframes, allowing enough time for uploading projects to the online platform. longwood and usf worked with offices of research to establish flexible timelines for digital teams. submission forms consider using forms or a system to collect student submissions. google forms, microsoft forms, or a learning management system such as canvas are ways to collect the projects. make sure to test these prior to the submission process. both universities used canvas during the 2020 student research symposiums to collect student projects. however, in 2021, longwood students (both graduate and undergraduate) submitted directly to forager one’s symposium platform because it was already integrated into the campus single sign-on service, enabling ease of submissions. for the graduate student research symposium in 2021, usf used microsoft forms to create a form that was tailored to file format preference. although this form was not used after the office of graduate studies went in another direction, symulevich felt it was an improvement from the previous year’s collection process due to the output of an excel spreadsheet for metadata collection for batch uploading purposes. abstract archiving institutions should consider allowing students to submit abstracts only. longwood allowed students to not submit complete presentations if they were planning to publish their projects. this may be more of an issue when students are working with faculty members on research to be published at a later date. promoting the symposium and creating engagement promote the event to increase student participation. this can be done both through social media and through university web presences. consider working with your campus marketing and communications department to broaden marketing beyond the library. this marketing can be both to gain student projects and to promote the event to the broader campus community. likewise, seek ways to promote engagement on the institutional repository or whatever platform is chosen. this could include using a third-party commenting feature as a way to further engage students with their scholarly topic. however, make sure to monitor commenting in some capacity to avoid spam. also, turn off commenting features after a certain period of time so as not to overburden students. commenting features and increased engagement via online platforms, like video and audio presentations, help avoid the negative impact of a lack of face-to-face interactions.28 information technology and libraries march 2022 using open access institutional repositories to save the student symposium | symulevich and hamilton 10 hybrid symposiums even after the end of the covid pandemic when events resume in-person, hybrid symposium models should be considered, as evidenced by longwood’s use of synchronous presentations using zoom. these links were integrated into the ir. osu is considering using hybrid solutions in the future as well.29 conclusion moving in-person student research symposiums to online platforms during a pandemic is challenging. but this process of creating online events allows students to continue to celebrate their highimpact research and contribute to the scholarly community. open access archiving of these projects has been successful based on download counts at longwood university and usf st. petersburg campus. the authors hope to continue to use innovative digital archiving to provide support for student research projects. remaining flexible and working with other departments on campus can lead to successful online events. the authors hope in-person events will eventually return; however, these online platforms can enhance student research symposiums, providing global access to high-impact student projects. acknowledgement the authors thank the collaborative teams at longwood university and university of south florida st. petersburg campus that helped make these student research symposiums happen and succeed during a very difficult time. endnotes 1 george d. kuh,

endnotes fagan 140 information technology and libraries | september 2006 visual search interfaces have been shown by researchers to assist users with information search and retrieval. recently, several major library vendors have added visual search interfaces or functions to their products. for public service librarians, perhaps the most critical area of interest is the extent to which visual search interfaces and text-based search interfaces support research. this study presents the results of eight full-scale usability tests of both the ebscohost basic search and visual search in the context of a large liberal arts university. l ike the web, online library research database interfaces continue to evolve. even with the smaller scope of library research databases, users can still suffer from information overload and may have difficulty in processing large results sets. web search-engine research has shown that the number of searchers viewing only the first results page has increased from 29 percent in 1997 to 73 percent in 2002 for united states-based web searchengines users.1 additionally, the mean number of results viewed per query in 2001 was 2.5 documents.2 this may indicate either increasing relevance in search results or an increase in simplistic web interactions. visual alternatives to search interfaces attempt to address some of the problems of information retrieval within large document sets. while research and development of visual search interfaces began well before the advent of the web, current research into visual web interfaces has continued to expand.3 within librarianship, the most visual interface research seems to focus on those that could be applied to large-scale digital library projects.4 although library products often have more metadata and organizational structure than the web, search engine-style interfaces adapted for field searching and boolean operators are still the most frequent approach to information retrieval.5 yet research has shown that visual interfaces to digital libraries offer great benefit to the user. zaphiris emphasizes the advantage of shifting the user’s mental load “from slow reading to faster perceptual processes such as visual pattern recognition.”6 according to borner and chen, visual interfaces can help users better understand search results and the interrelation of documents within the result set, and refine their search.7 in their discussion of the function of “overviews” in visual interfaces, greene and his colleagues say that overviews can help users make better decisions about potential relevance, and “extract gist more accurately and rapidly than traditional hit lists provided by search engines.”8 several library database vendors are implementing visual interfaces to navigate and display search results. serials solutions’ new federated search product, centralsearch, uses technology from vivisimo that “organizes search results into titled folders to build a clear, concise picture for its users.”9 ulrich’s fiction connection web site has used aquabrowser to help one “discover titles similar to books you already enjoy.”10 the queens library has also implemented aquabrowser to provide a graphical interface to its entire library’s collections.11 xreferplus maps search results to topics by making visual connections between terms.12 comabstracts, from cios, uses a similar concept map, although one cannot launch a search directly from the tool. groxis chose a circular style for its concept-mapping software, grokker. partnerships between groxis and stanford university began as early as 2004, and grokker is now being implemented at stanford university libraries academic and information resources.13 ebsco and groxis announced their partnership in march 2006.14 the ebscohost interface now features a visual search tab as an option that librarians can choose to leave on (by default) or turn off in ebsco’s administrator module. figure 1 shows a screenshot of the visual search interface. within the context of library research databases, visual searching likely provides a needed alternative from traditional, text-based searching. to test this hypothesis, james madison university libraries (jmu libraries) decided to conduct eight usability sessions with ebscohost’s new visual search, in coordination with ebsco and groxis. while this is by no means the first published usability test of vendor interfaces, the literature understandably reveals a far greater number of usability tests on in-house projects such as library web sites and customized catalog interfaces than on library database interfaces.15 it is hoped that by observing users try both the ebsco basic search and visual search, more understanding will be gained about user search behavior and the potential benefits of a visual approach. ฀ method the usability sessions were conducted at jmu, a large liberal arts university whose student population is mostly drawn from virginia and the northeastern region. only 10 percent of the students are from minority groups. jmu requires that all freshmen pass the online information skills seeking test (isst) before becoming a sophomore, and the libraries developed a web tutorial, “go for the gold,” to prepare students for the isst. therefore, usabiljody condit fagan usability testing of a large, multidisciplinary library database: basic search and visual search jody condit fagan (faganjc@jmu.edu) is digital services librarian at carrier library, james madison university, harrisonburg, virginia. usability testing of a large, multidisciplinary library database | fagan 141 ity-test participants were largely white, from the northeastern united states, and had exposure to basic information literacy instruction. jmu libraries’ usability lab is a small conference room with one computer workstation equipped with morae software.16 audio and video recordings of user speech and facial expressions, along with “detailed application and computer system data,” are captured by the software and combined into a searchable recording session for the usability tester to review. a screenshot of the morae analysis tool is shown in figure 2. the usability test script was developed in collaboration with representatives of ebsco and groxis. ebsco provided access to the beta version of visual search for the test, and groxis provided financial incentives for student participants. the test sessions and the results analysis, however, were conducted solely by the researcher and librarian facilitators. the visual search development team was provided with the results and video clips after analysis. usability study participants were recruited by posting an announcement to the jmu students’ web portal. a $25 gift certificate was offered as an incentive, and more than 140 students submitted a participation interest form. these were sorted by the number of years the student(s) had been at jmu to try to get as many novice users as possible. because so much of today’s student work is conducted in groups, four groups of two, as well as four individual sessions, were scheduled, for a total of twelve students. jmu librarians who had received both human-subjects training and an introduction to facilitation served as facilitators to the usability sessions. their role was to watch the time and ask open-ended questions to keep the student participants talking about what they were doing. the major research question it was hoped would be answered by the tests was, “to what extent does ebsco’s basic search interface and visual search interface support student research?” since the tests could not evaluate the entire research process, it was decided to focus on the development of the research topic. specifically, the goal was to find out how well each interface supported the intellectual process of the students in coming up with a topic, narrowing their topic, and performing searches on their chosen subtopics. an additional goal was to determine how well users were able to find and use the interface widgets and how satisfied the students felt after using the interfaces. the overall session was structured in this order: a pretest survey about the students’ research experience; a series of four tasks performed with ebscohost’s basic search; a series of three tasks performed with ebscohost’s visual search; and a posttest interview. both basic and visual search interfaces were used with academic search premier. each of the eight sessions was recorded in entirety by the morae software, and each recording was viewed in entirety. to try to gain some quantitative data, the researcher measured the time it took to complete each task. however, due to variables such as facilitator involvement and interaction between group members, the numbers did not lend themselves to comparison. also, it would not have been clear whether greater numbers indicated a positive or negative sign. taking longer to come up with subtopics, for example, could as easily be a sign of exploration and interested inquiry as it might be of frustration or failure. as such, the data are mostly qualitative in nature. figure 1. screenshot of ebscohost’s visual search figure 2. screenshot of morae recorder analysis tool 142 information technology and libraries | september 2006 ฀ results the student participants were generally underclassmen. two of the students, group 2, were in their third year at jmu. all others were in their first or second year. while students were drawn from a wide variety of majors, it is regrettable that there was not stronger representation from the humanities. when asked, “what do you normally use to do research?” six students answered an unqualified “google.” three other students mentioned internet search engines in their response. only two students gave the brand or product names of library research databases: one said, “pubmed, wilsonomnifile, and ebsco,” while the other, a counseling major, mentioned psycinfo and cinahl. when shown a screenshot of basic search, half of the students said they had used an ebsco database before. all of the participants said they had never before used a visual search interface. the full results from the individual pretest interviews are shown in figures 3 and 4. to begin the usability test, the facilitator started internet explorer and loaded the ebscohost basic search, which was set to have a single input box. the scripts for each task are listed in figure 5. note that task 4 was only featured in the basic search portion of the test. for task 1 on the basic search—coming up with a general topic—all of the participants began by using their own topics rather than choosing from the list of ideas. also, although they were asked to “spend some time on ebsco to come up with a possible general topic,” all but group 6 fulfilled this by simply thinking of a topic (sometimes after some discussion within the groups of two) and typing it in. with the exception of group 6, the size of the result set did not inspire topic changes. figure 6 summarizes the students’ searches and relative success on task 1. in retrospect, the tests might have yielded more straightforward findings if the students had been directed to choose from the provided list of topics, or even to use the same topic. however, part of the intention was to determine whether either interface was helpful in guiding the students’ topic development. it was hoped that by defining the scenario as writing a paper for class, their topic selection would reflect the realities of student research. however, it probably would have been better to have used the same topic for each session. task 2 asked participants to identify three subtopics, and task 3 asked them to refine their search to one subtopic and limit it to the past two years. a summary of these tasks appears in figure 7. a surprising finding during task 2 was that students did go past the first page of results. four groups went past the first page of results, while two groups did not get enough results for more than one page. the other two groups did not choose to look past the first page of results. this contrasts with jansen and spink’s findings, figure 3. results from pretest interview, groups 1–4 figure 4. results from pretest interview, groups 5–8 usability testing of a large, multidisciplinary library database | fagan 143 in which 73 percent of web searchers only view the first results page.17 another pleasant surprise was that students spent some time actually reading through results when they were searching for ways to narrow their topic. five groups scanned through both titles and abstracts, which requires clicking on the article titles to display the citation view. one of these five additionally chose to open full-text articles and look at the references to determine relevance. two groups scanned through the results pages only, but looked at both article titles and the subjects in the left-hand column. group 5 seemed to only scan the titles in the results list. this user behavior is also quite different than that found with web search-engine users. in one recent study by jansen and spink, more than 90 percent of the time, search-engine users viewed five or fewer documents per query.18 the five groups that chose to view the citation/abstract view by clicking on the title (groups 1, 2, 3, 4, and 6) identified subtopics that were significantly more interesting and plausible than the general topic they had come up with. from looking at their results, these groups were clearly identifying their subtopics from reading the abstracts and titles rather than just brainstorming. although group 2 had the weakest subtopics, going from the world baseball classic to specific players’ relationships to the classic and the home-run derby, they were working with a results set of but eleven items. the three groups that relied on scanning only the results list succeeded to an extent, but as a whole, the new subtopics would be much less satisfying to the scenario’s hypothetical professor. after scanning the titles on two pages of results, group 5 (an individual) ended up brainstorming her subtopics (prevention, intervention, and what an eating disorder looks like) based on her knowledge of the topic rather than drawing from the results. group 7 (a group of two) identified their subtopic (sand dunes) from the lefthand column on the results list. group 8 (an individual) picked up his subtopics (steroids in sports, president bush’s stance on steroids, and softball) from reading keywords in the article titles on the first page of results. since the subjects in the left-hand column were a new addition to basic search, the use of this area was also noted. four groups used the subjects in the left-hand column without prompting. two groups saw the subjects (i.e., ran the mouse over them) but did not use them. the remaining two groups made no action related to the subjects. a worrisome finding of tasks 2 and 3 was that most students had trouble with the default search being set to phrase-searching rather than to a boolean and. this can easily be seen in looking at the number of results the students came up with when they tried to refine their topics (figure 7). even though most students had some limiter still in effect (full text, last two years) when they first tried their new refined search, it was the phrasesearching that really hurt them. luckily, this figure 6. task 1, coming up with a general topic using basic search figure 5. tasks posed for each portion of the usability test. 144 information technology and libraries | september 2006 is a customizable setting in ebsco’s administrator module, and it is recommended that libraries enable the “proximity” expander to be set “on” by default, which will automatically combine search terms with and. task 4, finding a “recent article in the economist about the october earthquake in kashmir,” was designed to test the usability of the ebscohost publication search and limiter. it was listed as optional in case the facilitator was worried that time was an issue. four of the student groups—1, 2, 5, and 7—were posed the task. of these four groups, three relied entirely on the publication limiter on the refine search panel. group 1 chose to use the publication search. all four groups quickly and successfully completed this task. ฀ ฀additional questions during basic search tasks at various points during the three tasks in ebsco’s basic search, the students were asked to limit their results set to only full-text results, to find one peer-reviewed article, and to limit their search to the past two years. seven out of the eight student groups had no problem finding and using the ebscohost “refine search” panel, including the full-text check box, date limiter, and peerreviewed limiter. group 7 did not find the refine search panel or use its limiters until specifically guided by the facilitator near the end. this group had found other ways to apply limits: they used the “books/monographs” tab on the results list to limit to full text, and the results-list sorting function to limit to the past two years. after having seen the refine search panel, group 7 did use the “peer reviewed” check box to find their peer-reviewed article. toward the end of the basic search portion, students were asked to “save three of their results for later.” three groups demonstrated full use of the folder. an additional three groups started to use the folder and viewed the folder but did not use print, save, or e-mail. it is unclear whether they knew how to do so and just did not follow through, or whether they thought they had safely stored the items. two students did not use the folder at all, acting individually on items. one group used the “save” function but did not save each article. ฀ visual search similar to task 1, when using the basic search, students did not discover general topics by using the interface, but simply typed in a topic of interest. only two groups, 1 and 8, chose to try the same topic again. in the interests of processing time, visual search limits the search to the first 250 results retrieved. since jmu has set the default sort results to display in chronological order, the most recent 250 results were returned during these usability tests. figure 8 shows the students’ original search terms using visual search, the actions they took while looking for subtopics, and the subtopics they identified. additionally, if the subtopics they identified matched words on the screen, the location of those words is noted. three of the groups (1, 2, and 5) identified subtopics when looking at the labels on topic and subtopic circles. group 3 identified subtopics while looking at article titles as well as the subtopic circles. the members of group 6 identified subtopics while looking at the citation view and reading the abstract and full text, as well as rolling over article titles with their mice. it was not entirely clear where the student in group 4 got his subtopics from. two of the three subtopics did not seem to figure 7. basic search, task 2 and 3, coming up with subtopics. usability testing of a large, multidisciplinary library database | fagan 145 be represented in the display of the results set. his third subtopic was one of the labels from a subtopic circle. groups 7 and 8 both struggled with finding their subtopics. group 7 simply had a narrow topic (“jackalope”), and group 8 misspelled “steroids” and got few results for that reason. lacking many clusters, both groups tried typing additional terms into the title keyword box on the filter panel, resulting in fewer or zero results. for task 3, students were asked to limit their search to the last two years and to refine their search to a chosen subtopic (figure 9). particularly because the results set is limited to 250, it would have been better to have separated these two tasks: first to have them limit the content, then perhaps the date of the search. three groups, all groups of two, used the date limit first (2, 6, and 8). three groups (1, 3, and 6) narrowed the content of their search by typing a new search or additional keywords into the main search box. groups 2 and 4 narrowed the content of their search by clicking on the subtopic circles. note that this does not change the count of the number of results displayed in the filter panel. groups 5 and 7 tried typing keywords into the title keyword filter panel and also clicking on circles. both groups fared better with the latter approach. group 8 typed an additional keyword into the filter panel box to narrow his search. while five of the groups announced the subtopic to which they wanted to narrow their search before beginning to narrow their topic, groups 2, 7, and 8 began to interact with the interface and experiment with subtopics before choosing one. while groups 2 and 8 arrived at a subtopic and identified it, group 7 tried many experiments, but since their original topic (jackalope) was already narrow, they were not ultimately successful in identifying or searching on a subtopic. as with basic search, students were asked to save three articles for later. five of the groups (2, 4, 5, 6, and 8) used the “add to folder” function which appears in the citation view on the right-hand side of the screen. of these, three groups proceeded to “folder has items.” of these groups, two chose the “save” function. two groups used either “save” or “e-mail” to preserve individual items, rather than using the folder. one group experienced system slowness and was not able to load the full-record view in time to determine whether they would be able to save items for later. a concern that students may not realize is that in folder view or individually, the “save” button really just formats the records. the user must still use a browser function to save the formatted page. no student performed this function. figure 8. visual search, task 1 and 2, coming up with a general topic figure 9. visual search, task 3, searching on subtopic (before date limit, if possible) 146 information technology and libraries | september 2006 several students had some trouble with the mechanics of the filter panel, shown in figure 10. seven of the eight groups found and used the filter panel, originally hidden from view, without assistance. however, some users were not sure how the title keyword box related to the main search box. at least two groups typed the same search string into the title keyword box that they had already entered into the main search box. also, users were not sure whether they needed to click the search button after using the date limiter. however, in no case was a student unable to quickly recover from these areas of confusion. ฀ results of posttest interview at the end of the entire usability session, participants were asked several questions while looking at screenshots of each interface. a full list of posttest interview questions can be found in figure 11. when speaking about the strengths of basic search, seven of eight groups talked about the search options, such as field searching and limiters. the individual in group 1 mentioned “the ability to search in fields, especially for publications and within publications.” one of the students in group 3 mentioned that “i thought it was easier to specify the search for the full text and the peer reviewed—it had a separate page for that.” the student in group 4 added, “they give you all the filter options as opposed to the other one.” five of the eight groups also mentioned familiarity with the type of interface as a strength of basic search. since jmu has only had access to ebsco databases for less than a year, and half of the students admitted they had not used ebsco, it seemed their comments were with the style of interface more than their experience with the interface. the student in group 1 commented, “seems like the standard search engine.” group 2 noted, “it was organized in a way that we’re used to more,” and group 3 said, “it’s more traditional so it’s more similar to other programs.” half of the groups mentioned that basic search was clear or organized. group 6 explained, “it was nice how it was really clearly set out . . . like, everything’s in a line.” not surprisingly, visual search’s strengths surrounded the grouping of subtopics: seven of eight groups made some comment about this. the student in group 4 said, “it groups the articles for you better. it kinda like gives you the subtopics when you get into it and search it and that’s pretty cool.” the student in group 8 stated, “you can look and see an outline of where you want to go . . . it’s easy to pinpoint it on screen like that’s where i want to go with my research.” some of the other strengths mentioned about visual search were: showing a lot of information on one screen without scrolling (group 7) and the colorful nature of the interface. a student in group 2 added, “i like the circles and squares—the symbols register easily.” the only three weaknesses listed for basic search in response to the first question were: “not having a spot to put in words not to search for” (group 1); that, like internet search engines, basic search should have “a clip from the article that has the keyword in it, the line before and the line after” (group 6); and that basic search might be too broad, because “unless you narrow it, [you have to] type in keywords to narrow it down yourself” (group 7). figure 10. visual search filter panel figure 11. posttest interview questions usability testing of a large, multidisciplinary library database | fagan 147 with regard to weaknesses of visual search, half of the groups had some confusion about the content, partially due to the limited number of results. a student from group 7 declared, “it may not have as many results. . . . if you typed in ‘school’ on the other one, it might have . . . 8,000 pages [but] on this you have . . . 50 results.” the student in group 5 agreed, saying that with visual search, “they only show you a certain number of articles.” the student in group 1 said, “it’s kind of confusing when it breaks it up into the topics for you. it may be helpful for some other people, but for the way my mind works i like just having all my results displayed out like on the regular one.” half of the groups also made some comment that they were just not used to it. six of the groups were asked which one they would choose if they had class in one hour. (it is not clear why the facilitator did not ask this question of groups 3 and 8.) four groups (1, 2, 5, and 7) indicated basic search. one student in group 2 said, “i think it’s easier to use, but i don’t trust it.” the other in group 2 added, “it’s new and we’re not quite sure because every other search engine is you just type in words and it’s not graphical.” both students in group 7 commented that the familiarity of basic search was the reason they would use it for class in one hour. both groups 2 and 7 would later say that they liked the visual search interface better. two groups (4 and 6) chose visual search for the “class in one hour” scenario. the student in group 4 commented, “because it does cool things for you, makes it easier to find. otherwise you’re going through by title.” both these groups would later also say that they liked the visual search interface better. the students were also asked to describe two scenarios, one in which they would use basic search and one in which they would use visual search. four of the groups (1, 3, 5, and 6) said they would use basic search when they knew what information they needed. seven of the eight groups said they would use visual search for broad topics. all the students’ responses are given in figure 12. when asked which interface they preferred, the groups split evenly. comments from the four who preferred basic search (1, 3, 5, and 8) centered on the familiarity of the interface. the student in group 5 added, “the regular one . . . i like to get things done.” all four of these students had said they had used an ebsco database before. the two students who could list library research databases by name were both in this group. of the four who preferred visual search (2, 4, 6, and 7), three groups had never used ebsco before, though one of the students in group 7 thought he’d used it in the library web tutorial. group 2 commented, “it seemed like it had a lot more information . . . cool . . . futuristic.” the student in group 4 said, “it’s kind of like a little game. . . . like you’re trying to find the hidden piece.” group 7 commented that visual search was colorful and intriguing. the students in group 6 both stated “the visual one” in unison. one student said that visual search was more “[eye-catching] . . . it keeps you focused at what you are doing, i felt, instead of . . . words . . . you get to look at colors” and added later that it was “fun.” the other students in group 6 said, “i’m a very visual learner. so to see instead of having to read the categories, and say oh this is what makes sense, i see the circles like ‘abilities test’ or ‘academic achievement’ and i automatically know that’s what it is . . . and i can see how many articles are in it . . . and you click on it and it zooms in and you have all of them there.” the second student went on to add, “i’ve been teaching my mom how to use technology and the visual search would be so much easier for her to get, because its just looks like someone drew it on there like this is a general category and then it breaks it down.” other suggestions given during the free-comment portion of the survey were to have the filters from basic search appear on visual search (especially peer-reviewed); curiosity about when visual search would become available (at the time it was in beta test); and a suggestion to have generaleducation writing students write their first paper using visual search. figure 12. examples of two situations: one in which you would be more likely to use visual search, and one in which you would be more likely to use ebsco 148 information technology and libraries | september 2006 ฀ discussion this evaluation is limited both because most students chose different topics for each search interface, and because they only had time to research one topic in each interface. therefore, there could be an infinite number of scenarios in which they would have performed differently. however, this study does show that, for some students, or for some search topics, visual search will help students in a way that basic search may not. one hypothesis of this study was that within the context of library research databases, visual searching would provide a needed alternative from traditional, text-based searching. the success of the students was observed in three areas: the quality of the subtopics they identified after interacting with their search results; the improvement of the chosen subtopic over their chosen general topic, and the quality of the results they found for their subtopic search. the researcher made a best effort to compare topics and results sets and decide which interface helped the student groups to perform better. in addition, qualities that each interface seemed to contribute to the students’ search process were noted (figure 13). these qualities were determined by reviewing the video recordings and examining the ways in which either interface seemed to support the attitudes and behaviors of the students as they conducted their research tasks. when considering all three of these areas, four groups did not, overall, require visual search as an alternative to basic search (1, 3, 4, and 7). two of these groups (4 and 7) seemed to benefit from more focus when using the basic search interface. although visual search lent them more interaction and exploration (which may be why they said they preferred visual search), it seems the focus was more important to their performance. for the other two groups (1 and 3), basic search really supported the depth of inquiry and high interest in finding results. these two groups confirmed that they preferred basic search. for two groups (6 and 8), visual search seemed an equally viable alternative to basic search. for group 6, both interfaces seemed to support the group’s desire to explore; they said they preferred visual search. for the student in group 8, basic search seemed to orient him to the goal of finding results, while visual search supported a more exploratory approach. since, in his case, this exploratory approach did not turn out well in the area of finding results, it is not surprising that he ended up preferring basic search. the remaining two groups (2 and 5) performed better with visual search, upholding the hypothesis that an alternate search is needed. group 2 seemed bored and uninterested in the search process when using basic search even though they chose a topic of personal interest: “world baseball classic.” visual search caught their attention and sparked interest in the impersonal topic “global warming.” group 2 spent more time exploring while using the visual search interface, and in the posttest survey admitted that they preferred the visual search interface. the student in group 5 said she preferred basic search, and as a selfdescribed psycinfo user, seemed comfortable with the interface. yet for this test scenario, visual search made her think of new ideas and supported more real exploration during the search process. within each of the three areas, basic search appeared to have the upper hand for both the quality of the subtopics identified by the students, and in the improvement of the chosen subtopics over the general topics. this is at least partially explained by the limitation of visual search to the most recent 250 results. that is, as the students explored the visual search results, choosing subtopics would not relaunch a search on that subtopic, which would have engendered more and perhaps better subtopics. in the third area, the quality of the results set for the chosen topic, visual search seemed to have the upper hand if only because of the phrase-searching limitation present in jmu’s administrative settings for basic search. that is, students were often finding few or no results on their chosen subtopics in basic search. this study also had findings that seem to transcend figure 13: strengths of basic search and visual search in quality of subtopics, most improved topic, and result sets usability testing of a large, multidisciplinary library database | fagan 149 these interfaces and the underlying database. first, libraries should strongly consider changing their database default searching from phrase searching to a boolean and, if possible. (this is possible in ebsco using the administrative module.) second, most students did not have trouble finding or using the interface widgets to perform limiting functions, with the one exception being some confusion about the relationship between the visual search filters and main search box. unlike some research into web search behavior, students may well travel beyond the first page of results and view more than just a few documents when determining relevance. finally, the presence of subject terms in both interfaces proved to be an aid to understanding results sets. this study also pointed out some improvements that could be made to visual search. first, it would be great if visual search returned more than 250 results in the initial set, or at least provided an overview of the size, type, and extent of objects using available metadata.19 however, even with today’s high-speed connections, result-set size will need to be balanced with performance. perhaps, as students click on subtopics, the software could rerun the search so that the results set does not stay limited to the original 250. on a minor note, for both basic and visual search, greater care should be taken to make sure users understand how the save function works and alert users to the need to use the browser function to complete the process. it should be noted that ebsco has not stopped developing visual search, and many of these improvements may well be on their way. ebsco says it will be adding more support for limiters, display preferences, and contextual text result-list viewing at some point in the future. these feature sets can currently be viewed on grokker.com. an important area for future research is user behavior in library subscription databases. while these usability tests provide a qualitative evaluation of a specific interface, it would be worthwhile to have a more reliable understanding about students’ searching behavior in library databases across similar interfaces. since public service librarians deal primarily with users who have self-identified as needing help, their experience does not always describe the behavior of all users. furthermore, studies of web search behavior may not apply directly to searching in research databases. specifically, students’ use of subject terms in both interfaces could be explored. half of the student groups in this study chose to use the basic search subject clusters in the left-hand column on the results page, despite the fact that they had never seen them before (this was a beta-test feature). is this typical? would this strategy hold up to a variety of research topics? another interesting question is the use of a single search box versus several search boxes arrayed in rows (to assist in constructing boolean and field searching). in the ebsco administrative module, librarians can choose either option. based on research rather than anecdotal evidence, which is best? another option is the default sort: historically, at jmu libraries, this has been a chronological sort. does this cause problems for relevance-thinking students? finally, the issue of collaboration in student research using library research databases would be a fascinating topic. certainly, these usability recordings could be reviewed with a mind to capturing the differences between individuals and groups of two, but there may be better designs for a more focused study of this topic. ฀ conclusion if you take away one conclusion from this study, let it be this: do not hesitate to try visual search with your users! information providers must balance investments in cutting-edge technology with the demands of their users. libraries and librarians, of course, are a key user group for information providers. a critical need in librarianship is to become familiar with the newest technology solutions, particularly with regard to searching, in order to provide vendors with informed feedback about which technologies to pursue. by using and teaching new visual search alternatives, librarians will be poised to influence the further development of alternatives to text-based searching. references and notes 1. bernard j. jansen and amanda spink, “how are we searching the world wide web?

comeaux information technology and libraries | june 2021 https://doi.org/10.6017/ital.v40i2.12629 abstract the covid-19 pandemic has greatly impacted higher education, including academic libraries. this paper compares the use of library resources (including interlibrary loan, website and discovery tool pageviews, database use, patron interactions, etc.) at three university libraries before and after the pandemic. the latter part of the 2019 and 2020 spring semesters are the time frames of focus, although two control time frames from earlier in those semesters are used to determine how the semesters differed when the coronavirus was not a factor. the institutions experienced similar patterns of use across many metrics. introduction the year 2020 will be remembered as the year of the novel coronavirus (covid-19). around the world, hundreds of thousands of people died from the disease, schools and businesses shut their doors, wearing masks in public places became commonplace, and unemployment soared.1 everyone and everything changed in ways large and small, and libraries were no exception. this study measures changes in use of library resources during time frames of covid-19 closures at three different institutions: louisiana state university, northeastern illinois university, and valparaiso university. these three universities vary in size (large to medium), control (two public, one private), basic carnegie classification (doctoral-very high research, master’s, and doctoral/ professional), and setting (two primarily non-residential and one highly residential).2 despite their differences, these institutions experienced similar patterns of use across many categories. key findings: • the pandemic affected the three institutions studied on a continuum, with the least impact at the largest school, and the biggest drop in use seen at the smallest school. • use of all three libraries’ websites as well as the discovery tools/catalogs and major databases decreased during the covid time frame. • all three libraries experienced an increase in virtual communication. background louisiana state university louisiana state university (lsu) is the flagship institution of louisiana and is one of only 22 prestigious universities nationwide holding land-grant, sea-grant, and space-grant status. the main campus is in baton rouge, has the carnegie basic classification “doctoral universities: very ruth sara connell (ruth.connell@valpo.edu) is professor of library science & director of systems, valparaiso university. lisa c. wallis (l-wallis@neiu.edu) is associate dean of libraries and eresources & systems librarian, northeastern illinois university. david comeaux (davidcomeaux@lsu.edu) is systems and discovery librarian, louisiana state

library resources | connell, wallis, and comeaux 2 high research activity,” is primarily non-residential, and has a student full-time equivalent (fte) of about 30,000.3 lsu library is the university’s main library and a center of campus life for both students and faculty, and it houses approximately three million physical items (print books, media, and serials).4 before the onset of covid-19, lsu library was open 24/5 (24 hours sunday-thursday) plus weekend hours, with a 24/7 schedule during finals. as of july 30, 2020, it had 100 employees, of which 39 were librarians. lsu library staff, like all nonessential lsu staff, last reported to work in-person on monday, march 16. the previous day, the state’s governor ordered a statewide stay-at-home order, restricting events and closing venues. that monday, library it employees hurriedly assisted other staff in preparing to work remotely. near the end of the day, the university’s president sent an email asking all employees to work from home until further notice. classes were canceled for the week to allow instructors to prepare for remote teaching. the following week, march 23, was the beginning of spring break. classes resumed online-only on march 30. the libraries remained closed through the duration of the spring semester. despite the closure, the libraries continued to serve patrons. librarians continued to assist students through email and zoom-based sessions. the catalog and discovery systems remained available, and staff continued to fill article and book chapter requests through interlibrary loan and document delivery. northeastern illinois university northeastern illinois university (neiu) is a public, comprehensive, multicultural university located on the north side of chicago. it has an enrollment of approximately 7,000 students in undergraduate and graduate programs among three colleges: arts and sciences, education, and business. while currently classified in the “master’s colleges and universities: larger programs” category, neiu is undergoing a major enrollment shift due to the state of illinois’ failure to provide a budget during the period 2015–2017 and, now, the covid crisis.5 the spring 2019 fte was 4,644 (83% undergraduate), while in spring 2020, fte was 4,404 (80% undergraduate). the campus is primarily a commuter campus. the neiu libraries offer library services at three locations in chicago. altogether, the three libraries house approximately 500,000 physical books, media, and serials.6 in spring 2020, the neiu libraries employed 12 people in positions requiring an mls—including the dean and associate dean of libraries—and 18 staff. the main library is typically open 92 hours per week. neiu’s spring break typically falls at the same point in the semester every year, with the spring 2020 break scheduled to begin on saturday, march 14. the week prior to spring break, neiu’s president announced that the break would be extended by an extra week to allow instructors to move instruction to alternatives from face-to-face teaching. the neiu libraries closed its doors on wednesday, march 18 at 6 p.m., and library faculty and staff began working from home. the libraries were able to offer continued reference and instruction by chat, email, phone, and google meet and to fill article and book chapter requests electronically. no physical materials were available, as the statewide delivery system supporting borrowing among academic libraries stopped its services on march 16. alternative instruction resumed on monday, march 30 for all students. information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 3 valparaiso university valparaiso university (valpo) is a private, not-for-profit, highly residential, four-year university in northwest indiana. its carnegie basic classification is “doctoral/professional universities,” although it serves a largely undergraduate student population (90% of fte in spring 2020). the graduate programs serve fewer than 500 students. during the time frame of this study, valpo’s fte ranged from 3,449 (spring 2019) to 3,147 (spring 2020).7 there is one library on campus. the christopher center for library and information resources has approximately 450,000 items in its print collection.8 during the fall and spring semesters (excluding breaks), the library is open 113 hours per week. as of fall 2020, the library employed 19 people: 10 librarians (including the dean) and nine staff members. this is four fewer positions than before the pandemic; due to covid-19 funding cuts, three staff members were laid off and one open librarian position was eliminated. valpo is unusual in that it has a two-week spring break which always falls on the first full two weeks in march. in 2020, spring break coincided with the burgeoning covid-19 crisis. during the second week of spring break, campus administration announced that campus would remain open, but classes would go online immediately following the break, starting monday, march 16. on march 16, the christopher center library moved to reduced hours (open 67.5 hours per week). as the fallout from the pandemic rapidly unfolded, hours were further reduced four days later. at the close of business on tuesday, march 24, in accordance with the state of indiana’s stay-at-home order, the physical building closed, although library faculty and staff continued to work from home. literature review preparing and responding to pandemics and other disasters libraries have long understood the need to prepare for disasters and have chronicled their struggles with disasters both natural and man-made. library collections have been lost due to fires and floods, and libraries have been forced to drastically alter their service models in response. the literature on this topic includes surveys of libraries regarding their emergency preparedness, advice on preparing disaster recovery plans, and recovering or replacing lost collections.9 one particularly prescient article describes the work done at the university of minnesota’s school of public health.10 two librarians joined a task force to prepare the school to function through an influenza pandemic. they focused on two scenarios. one was the onset of a pandemic mid semester, forcing schools to close for weeks or even through the duration of the semester. the other was an even longer (9to 18-month) school closure. both scenarios included implementing social distancing practices now familiar to us all. the task force provided many recommendations to enable continuity of online teaching in the event of a pandemic, but none dealt specifically with libraries. resource use during building disruptions previous studies have studied the impact on the use of library resources during building disruptions, generally due to renovations. in the studies reviewed, these libraries moved to temporary locations and still had some physical space available to students. this differs from the complete closure experienced by most libraries due to covid-19. typically, library services and resources are used less when normal building operations are disrupted, but there are exceptions. information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 4 in 1999, the library at eastern illinois university closed for 31 months. library services were relocated elsewhere. overall, the library experienced a “sharp drop in the use of library resources and services,” although one bright spot of growth was in interlibrary loan use, which went up by 16%.11 however, the authors note that this increase may be due to patrons placing requests for items owned by eiu that were difficult to access. mcneese state university in louisiana started a multiyear library renovation in 2012, during which the library’s personnel, services, and a small subset of the collection were relocated to a ballroom in the student union. a 2016 article discusses effects on library services half-way through the disruption. in reviewing the literature, the author found, “the longer students and faculty are not allowed access to the library building, the more usage statistics such as circulation, interlibrary loan (ill), and instruction decrease.”12 mcneese experienced a 22% decrease in interlibrary loan requests (borrowing and lending), a 51% decrease in the use of e-books, and a 62% decline in reference transactions. the author noted that “nearly every library service experienced a precipitous decline.”13 pepperdine university bucked the trend of sharp decreases during their 2016–2017 renovation. they experienced a dramatic increase in the number of interlibrary loan requests, both for borrowing (33%) and lending (375%), likely related to their decision to join rapid-ill at the beginning of the renovation. conversely, there was a slight decrease (10%) in borrowing from the california statewide consortium. pepperdine’s e-book usage remained fairly steady and actually increased 3% during the disruption. as expected, their in-person questions decreased while in a temporary facility, although chat and email reference questions increased by 30%.14 covid-19 impact though the coronavirus was first discovered to have reached the united states in january 2020, it was not until late february that american colleges and universities began to implement travel restrictions for students and staff and to develop plans for potential closure. 15 by early march 2020 the us department of education had developed guidelines for the coronavirus’ impact on distance learning and financial aid.16 the topic was also the subject of numerous articles on higher education websites such as the chronicle of higher education and inside higher ed. in march 2020, when the impact of covid-19 began to reverberate around the united states, virtually all libraries closed.17 the american library association (ala) conducted a survey of libraries of all types in may and reported that the majority of academic libraries had already lost funding, or anticipated losing funding within the next year, for staff, new hires, professional development, print collections, programs, and services.18 the press release for the ala survey stated that “survey respondents shared leaps in the use of digital content, online learning, and virtual programs.”19 however, a review of the survey instrument reveals that no questions were asked about use of these resources, so it is unclear where this assertion comes from.20 the survey included opportunities to leave comments, so it may be that the leaps in use mentioned in the ala press release is anecdotal. although libraries have never faced a global pandemic in modern times, previous research indicates library building disruptions generally reduce use, not cause it to increase as described in the press release. academic libraries were among the last facilities to close on many campuses, as they were viewed as essential for students.21 however, as early as the week of march 9, 7% of academic libraries reported that they had stopped circulating physical materials. in addition, building and face-toinformation technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 5 face reference desk staffing began to be scaled back, with 28% of reporting libraries doing no faceto-face reference by the end of that week.22 complete closure of academic library physical facilities became the norm by mid-march, with vocal advocacy for that measure expressed by both the american library association and the association of college and research libraries.23 apart from library instruction, the coronavirus did not so much force academic libraries to move online as to temporarily suspend physical and in-person services. by 2020, provision of online services—including book, article, and media circulation and email and chat reference—was nothing new for libraries. recent years have seen increased migration to cloud-based systems, eliminating the need for library work to be done using specific client software on library staff computers. academic libraries and vendors alike promoted the ability of their institutions and computer systems to handle the covid-19 crisis with minimal disruption.24 the international coalition of library consortia (icolc) issued a statement on march 13, 2020 , asking vendors to lift many of the usual licensing restrictions and opening access to the 391 million students affected by school and library shutdowns.25 publishers and vendors quickly began to remove paywalls between users and their online collections, either for free without library mediation or upon library request. icolc followed up by starting a comprehensive list of these materials on march 16, 2020.26 despite increased access to online collections, library resource use was disrupted. no matter how many services can be offered online, plenty of students and faculty still use traditional items such as print books. given the circumstances of covid-19, with sudden and lasting limits on access to physical materials and space, academic libraries began to promote online equivalents of th ese, such as the hathitrust emergency temporary access service (etas), which penn state reported offered “reading access to more than 48% of the libraries’ print collections.”27 upon seeing the collected mass of print books students returned prior to leaving campus due to covid -19, librarian nora dimmock of brown university’s john jay library identified the need to move “more intentionally” to e-books over print books in future purchasing decisions.28 methodology in order to determine whether the covid-19 pandemic affected use of library systems and resources, the researchers compared usage statistics from a covid-affected time frame in 2020 to the same time frame in 2019. these will be called the covid 2019 and covid 2020 time frames (or covid time frames collectively). because there could be other factors influencing use, such as differences in student fte between the two years, the researchers also pulled data from control time frames to compare earlier in the spring semesters. these control time frames were unaffected by covid in both 2019 and 2020. these will be called the control 2019 and control 2020 time frames (or control time frames collectively). by including data from the control time frames, we were able to determine whether there were trends affecting usage differences before the pandemic hit. as an example, lsu’s catalog pageviews were down 5% from the previous year during the first part of the semester unaffected by covid-19. for the latter part of the semester affected by covid-19, catalog use fell 25% as compared to the previous year. the control time frame comparison shows that catalog use was already in decline before the pandemic; therefore, some of the 25% decline is likely due to factors other than covid-19. the baseline factored difference is −20% (−5% + x = −25%; x = information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 6 −20%). figures 2, 4, and 6 illustrate the percentage of differences in covid time frames from determined baselines. each of the three researchers determined the control and covid time frames for their own institutions. because the academic calendars vary widely between the three institutions, the time frames of study also differ. the absolutes for each institution were: • the 2019 and 2020 control time frames were the same number of days • the 2019 and 2020 covid time frames were the same number of days (but the control time frames were not the same length as the covid time frames) • if a time frame from one year contained a special calendar event (e.g., spring break, mardi gras holiday, etc.), the researchers made sure the corresponding time frame from the other year also included that event. table 1. dates of institutions’ control & covid comparison time frames (excluding ebsco and proquest)

through tuesday, may 12 the primary concern was to ensure that each institution was comparing like time frames to like time frames within its own academic calendar. the variability of institutional calendars means that the data cannot be compared between institutions. for the major database platforms, the control and covid time frames differ from the other areas measured due to limitations of the statistical platforms. ebsco and proquest platforms allow reports to be run on full months only; partial month statistics cannot be pulled. for that reason, for the major database platforms alone, the control time frame is january through february, and the covid time frame is april through may. because 2020 was a leap year, february 2020 had one more day than february 2019. this means that the 2019 control time frame had 59 days while the 2020 control time frame had 60 days. the extra day could account for an increase in use of approximately 2%. when evaluating use of database platforms, there are several metrics from which to choose. the authors chose full text downloads (the counter metric known as total item requests) because it is the same across reports. there are different search metrics in platform and database reports, so the authors chose to focus on the consistency of the full text download metric. when considering information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 7 e-resource use during covid-19, another factor to consider is that many publishers removed some or all of their paywalls as the pandemic began. according to counter, the non-profit organization that regulates standards for usage data: as a result of this open content, usage may appear to go down during this period. this is because many of your users will be working from home, outside of your institution’s ip range and not authenticated. this means that the publishers are unable to attribute this usage to your institution.29 the journal platforms (wiley, sage, etc.) were more likely to be affected by this consideration than ebsco and proquest, who did not remove paywalls for databases of interest to academic audiences. the researchers determined which metrics to harvest. the following were selected: • main website usage • catalog usage • discovery tool usage • libguides usage (database a–z lists and guide views) • interlibrary loan article requests received (for both lending and borrowing) • sfx document delivery clickthroughs • ebsco and proquest total item requests (full text downloads) • patron interactions (chat questions, research consultations, ask-a-librarian) the three institutions use different products for discovery tools, chat reference, and interlibrary loan, so reporting mechanisms also vary. however, in general a combination of google analytics pageviews and vendors’ own reporting systems were used to pull the data. neiu libraries migrated from illiad to tipasa in june 2019, so it was not possible to gather comparable daily statistics for interlibrary loan request comparisons. since neiu did not have interlibrary loan data available that compared 2019 to 2020, the sfx report on document delivery clickthroughs was used as a proxy measure. when full text of an item is not available in a database, the docdel clickthroughs indicate that the user went to the sfx menu and then the tipasa interlibrary loan request page. because of various factors, not all data points are available for the three institutions. for example, neiu is part of the carli consortium. it was decided by a carli committee a few years ago that google analytics would not be used in the shared catalog in order to protect users’ privacy, s o the catalog usage data point is missing for neiu. neiu and valpo have chat service data; lsu now has chat but did not during the time frames under investigation. when data are not available, they are missing from the tables and results. results louisiana state university lsu’s data present a mixed picture. while the use of libguides rose, use of the libraries’ website, discovery system, and catalog all declined during the covid-enforced closure. while downloads through ebsco increased during the covid time frame by 30%, that is less than the increase information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 8 during the control time frame (37%), resulting in a baseline-factored decrease. interlibrary loan requests and

dropped dramatically during the covid 2020 time frame. however, use of some resources was already lower overall in 2020 than in 2019, even in the control time frame. illinois has experienced a tumultuous few years, with state universities starting new fiscal years without budgets in 2015 and 2016. this has led to a steady decrease in enrollment at public regional universities, as students sought to attend more stable institutions out of state.30 neiu was hit particularly hard, experiencing a 25% drop in enrollment between fall 2015 and fall 2019.31 so, it is likely some of the decrease in 2020 was due to lower enrollment. areas that saw growth in covid time frame 2020 were chat and reference consultations and interlibrary loan clickthroughs from sfx (see table 3). table 3. neiu: use

overall, usage of valparaiso university’s library resources dropped dramatically during the part of the 2020 spring semester affected by covid-19 (see table 4). reductions occurred in all areas except chat assistance. if you consider that usage was up in most categories during the pre-covid19 part of the semester compared to the previous year, the decline during the latter part of the semester is even more significant. the two exceptions to this pattern of covid-related net reduction were chat questions and interlibrary loan lending requests received (see figure 6). table 4. valpo: use of

louisiana state university usage of the libraries’ website, discovery system, and catalog all declined during the covidenforced closure. use of the main library site has been steadily declining since 2012. lsu library’s main website saw reduced traffic in both 2020 time frames, but this reduction was particularly dramatic during the covid-19 pandemic. catalog use has also been declining but experienced a sharp decline of 25% during the covid closure. catalog use regularly drops when the library is closed, at least partially owing to the fact that library staff are heavy catalog users. also, the catalog is largely used by patrons seeking print items and, with the closure of the library building, patrons were less likely to search for print items. therefore, a drop could be expected, but such an extreme reduction was a surprise. usage of the main discovery system (eds) followed a similar trajectory. as most discovery searches begin on the library website’s home page, a decline in discovery use would logically follow a decline in website usage. eds pageviews declined between 2019 and 2020 during the control time frame by 6% but declined much more sharply during the covid time frame. interlibrary loan requests (borrowing/document delivery and lending) rose considerably during the closure. one factor in the borrowing/document delivery increase was that document delivery was opened up to undergraduates during the covid 2020 time frame; this service was not available to that patron group during the control time frames and the covid 2019 time frame. downloads through ebsco, typically lsu’s busiest platform, increased in both the control time frame (37%) and covid time frame (30%), resulting in a baseline-factored decrease of 6% (rounded to the nearest percent). proquest use was less straightforward to interpret. while there was a dramatic decrease in downloads between 2019 and 2020, that seems to owe more to an unusually high usage in the 2019 covid time frame rather than a precipitous drop in the 2020 covid time frame. information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 15 lsu uses springshare’s popular libguides product, both for its list of databases (databases a–z) and as a platform for research guides. usage of the databases a–z page was minimally impacted in the covid time frame. however, overall guide usage rose significantly at 56%. at least some of this is due to the creation of a covid-specific research guide. this guide included descriptions and links to various electronic resources which vendors had made freely available during the crisis. that page alone had nearly 1,700 views in the covid time frame. but other pages with no clear connection to covid also had significant increases. this may reflect students feeling the need to consult electronic guides to compensate for lack of in-person access to librarians. the covid closure did have an enormous impact on usage of lsu’s patron support system. this system, labeled “ask us!”, handled 108 tickets in the 2020 covid time frame, compared to 17 in 2019. while this system’s use was trending upward in the control time frame as well, the jump in use during the covid-19 closure was notable. while many of the tickets were similar to questions asked when the libraries were open, many others were clearly related to the library’s closure. for example, several inquiries were in reference to alternate access to print items (such as scanning and delivering electronic versions of book chapters). there were also inquiries about when the building might reopen, and when patrons might be able to access print items that had been placed on hold. northeastern illinois university the library’s website is part of the university’s drupal content management system, which restricts the library’s ability to design and structure content. for that reason, much of the high impact library content is stored on third-party sites, like libguides or worldcat discovery. while the library directs users to start their research on the main website, users typically immediately follow a link that leads them to one of those third-party resources. usage of the library website and resources linked from the website both dropped. sfx document delivery clickthroughs, which pass users through to neiu’s interlibrary loan request pages, saw increases overall in 2020 compared to 2019. this is not surprising, given that neiu was forced to cancel two “big deal” packages at the end of 2019. the neiu libraries’ chat service was one of the resources that experienced increased usage during the covid 2020 time frame. an informal review of questions coming in during the early covid closure showed that most respondents were asking about building hours or returning or checking out materials. while the library website was immediately updated with covid-related closure information, the chat button is easily spotted and readily available, while the hours and materials information required clicking additional links. research consultations also increased. as the physical reference desk was no longer available, students and faculty were directed to use email or set up subject librarian google meet appointments for those questions where they may have usually visited the desk. an increase of 31% in these interactions demonstrates that users still needed librarian assistance with research and course-related questions in the time of covid. valparaiso university when evaluating valpo’s interlibrary loan demand, only article requests (for both borrowing/document delivery and lending) were considered; loans were excluded. demand from valpo patrons fell 32% during the time frame affected by covid-19. despite lack of access to the print collection once the pandemic hit, net lending demand from electronic resources rose slightly. information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 16 catalog use was in decline before covid hit. this is likely due to the increased reliance on the library’s discovery tool, which includes records for all materials held in the catalog. however, the difference in use seen during the pandemic is striking; net use fell 62%. because patrons use the catalog to access information about the library’s physical collection and the library was closed, this precipitous decline is not surprising. overall discovery tool (summon) use also fell during the 2020 covid time frame (20%). valparaiso university subscribes to approximately 60 ebsco databases and 30 proquest databases, making them valpo’s most popular database vendors. both saw declines, but in proquest more than ebsco. the library’s main website has slightly more than 100 pages, and although it serves as a starting point to reach many of the library’s other resources on different platforms (databases, libguides, etc.) it still receives considerable use: 147,125 pageviews in the 2019 calendar year. high-use pages include hours, the library directory, departments such as interlibrary loan and archives & special collections, and the listing of liaison librarians. the main website experienced a net 45% drop during the time frame affected by covid-19. valpo uses libguides for two primary purposes: to organize and share approximately 200 databases using the product’s a–z database list, and to deliver subject-specific and instruction content. the a–z lists are heavily used by students and faculty across campus. however, during the pandemic, net usage of the databases fell 17%. the net decrease in libguides views was approximately the same at −20%. seemingly, patrons had increased need for chat reference during the pandemic, although valpo receives a relatively small number of chat questions. during the first part of the spring 2020 semester unaffected by covid, valpo received six more questions over the same time frame in 2019. during the covid-affected part of the 2020 semester, usage jumped from 20 chats to 37 chats. again, these numbers are small, so caution should be used in interpretation, but considering the baseline change from the control time frame, there was a net 62% jump in usage for chat reference during the covid time frame. commonalities and trends while the study did not set out to compare usage among the three institutions, some clear patterns did emerge. use of all three libraries’ websites as well as the discovery tools/catalogs and major databases decreased during the covid time frame. a number of explanations could apply. for instance, regarding library website usage, libraries’ public computers are often set to open to the libraries home pages whenever a new browser is launched. when those computers are not in use, such as when library buildings are closed, students do not automatically start their research on those pages. even though students did continue to interact with librarians and library staff through virtual methods, in-person reference encounters were not possible during covid. many patron interactions begin with librarians demonstrating how to start research at the library home page, moving on to find databases or conduct searches in the discovery tool or catalog. without direct librarian guidance, it is not surprising that students do not start their research at library tools. whether it is because they do not realize library resources are available off campus or they have become fond of free web search tools such as google scholar, most public services librarians would expect a decrease in library resource usage when students are not on campus. information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis, and comeaux 17 with the exception of lsu’s libguides usage, the results of this study do not support the ala assertion that covid led to “leaps in the use of digital content” by library patrons. it is not surprising to see that all three libraries experienced an increase in virtual communication methods, as chat, email, and online meetings were the only means of student-librarian communication once campuses closed. no longer could students catch library staff in the stacks or at a service desk to ask quick—and often uncounted—questions. instead, interactions were more easily measured through the virtual trails they left behind. it would be difficult to determine whether overall student-librarian interaction increased or decreased during the covid time frame as compared to “normal” times. data only show that students did continue to seek help from libraries even when the buildings were closed. individual institutions noted some within–time frame usage patterns. for instance, valpo found that the drop in usage was more dramatic during the first part of the covid 2020 time frame and improved during the latter part of the covid time frame. initially, students were probably in sinkor-swim mode, with school assignments having a lower priority in their lives. after the first month or so, students and faculty may have been able to start thinking about research needs more. valparaiso university fared the worst of the three institutions, with net decreases in eight out of ten of the areas studied (80%) (see table 4). neiu had decreases in six out of nine areas (67%) and lsu, the largest institution, broke even with five out of ten (50%) areas showing decreases. valpo has a carnegie classification of highly residential, while lsu and neiu are primarily nonresidential. it could be that the residential nature of valpo’s campus more negatively impacted use when students were away from campus. lsu, a state flagship, has a higher percentage of graduate students than valpo or neiu. it seems likely that graduate students would be more determined to continue research activities during the closure than undergraduates, which may explain the smaller decrease. this could be an area of further research. conclusion as the pandemic continues and universities plan for altered learning environments into the fall, will there be a rebound in library system and resource usage, or will the dramatic dip seen during immediate covid time frame continue? nearly every day there are multiple webinars for academic libraries, their administrators, and their staff members to share their stories, compare their experiences, and help guide each other for operating in the new normal. librarians have had time to adjust typical pedagogical practices, learn new virtual technologies, and develop outreach plans to ensure continued library instruction in remote and online environments. other changes to library practice may include an even greater shift in acquisitions from print to electronic resources. services for distance students might become a greater point of emphasis. faculty, too, have had time to reevaluate their syllabi and identify support needs for themselves and their students as courses go online. as with so many areas of life these days, the outcomes of this work remain uncertain. information technology and libraries june 2021 the impact of covid-19 on the use of academic library resources | connell, wallis,

information technology and libraries | june 2021 https://doi.org/10.6017/ital.v40i2.12835 abstract discovery environments are ubiquitous in academic libraries but studying their effectiveness and use in an academic environment has mostly centered around user satisfaction, experience, and task analysis. this study aims to create a quantitative, reproducible framework to test the relevancy of results and the overall success of washington state university’s discovery environment (primo by ex libris). within this framework, the authors use bibliographic citations from student research papers submitted as part of a required university class as the proxy for relevancy. in the context of this study, the researchers created a testing model that includes: (1) a process to produce machine-generated keywords from a corpus of research papers to compare against a set of human-created keywords, (2) a machine process to query a discovery environment to produce search result lists to compare against citation lists, and (3) four metrics to measure the comparative success of different search strategies and the relevancy of the results. this framework is used to move beyond a sentiment or task-based analysis to measure if materials cited in student papers appear in the results list of a production discovery environment. while this initial test of the framework produced fewer matches between researcher-generated search results and student bibliography sources than expected, the authors note that faceted searches represent a greater success rate when compared to open-ended searches. future work will include comparative (a/b) testing of commonly deployed discovery layer configurations and limiters to measure the impact of local decisions on discovery layer efficacy as well as noting where in the results list a citation match occurs. introduction discovery environments are ubiquitous in academic libraries as all but two libraries in the association of research libraries (arl) report using a discovery environment, and they continue to gain traction in other library settings.1 the one-stop shopping model of discovery environments is one of their most alluring features as it closely resembles searching the open web. this familiarity allows users who are accustomed to searching the web to feel comfortable searching the library catalog without fear of encountering a “failed” search (zero result set). discovery environments seldom fail to return results as even the most rudimentary or naïve search strategy will return something for a user. this idea of “returning something” has been anecdotally noted as a positive as it ensures the user does not give up and allows novices to be successful with limited search sophistication or prior instruction from information professionals. one of the potential negatives to this approach however is the sheer volume of material that is returned per search query. library discovery environments often present thousands, if not millions, of search results from an initial search query. this emulation of google is essentially blake l. galbreath (blake.galbreath@wsu.edu) is core services

framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 2 making the time-honored study of relevancy (precision/recall) moot. how can one determine the number of relevant documents in a search query if the number of documents returned is becoming limitless? this study aims to create a quantitative, reproducible framework to test the relevancy of results returned from, and the overall efficacy of, a library discovery environment, in this case, ex libris primo. within this framework, the authors compare the results returned in model primo search queries against the bibliographic citations used in students’ research papers. background the university common requirements (ucore) curriculum, implemented in fall 2012, was a major redesign of the washington state university (wsu) undergraduate general education program. ucore is comprised of required categories of classes designed to build student proficiency in the seven undergraduate learning goals.2 roots of contemporary issues (rci) is the sole mandated undergraduate course under the ucore system.3 during the 2018–2019 academic year, over 4,500 students were enrolled in rci at wsu, the vast majority being first-year students. this paper utilizes data from the rci library research project, a term-length research experience with four central assignments designed to familiarize students with the fundamentals of quality research and a cumulative research paper where they utilize the skills learned. the research project components are spaced evenly throughout the term; students are guided along the research process from general topic formation, to research question generation, to thesis statement defense in the final paper. students are tasked with finding sources of particular resource types (e.g., journal articles), describing the value of these sources for their research, and citing them properly in chicago style. wsu libraries uses the discovery environment primo, an ex libris product, to provide resources to its patrons.4 specifically, wsu libraries uses the new user interface version of primo, which incorporates search results from the primo central index (pci) in its default search. primo, like all discovery environments, provides results with a wide variety of resource types so rci students can use it at all stages of the term research project. students use it in the pursuit of contemporary newspaper articles, history monographs, history journal articles, and primary sources. in this article, the authors focus on the versatility of primo, using rci student paper bibliographies as the central data source for the project. literature review the need for assessment of library resources and services in higher education has been welldocumented. libraries are increasingly asked to provide tangible evidence they aid student information literacy skill development and thus advance achievement of institutional learning outcomes. accrediting bodies acknowledge, “the importance of information literacy skills, and most accreditation standards have strengthened their emphasis on the teaching roles of libraries.”5 oakleaf and kaske also stress the importance of librarians choosing assessments that can contribute to university-wide assessment efforts, noting they are preferable to assessments that only benefit libraries.6 the washington state university libraries is committed to assessment of its resources and services, with primo as a central target resource, and with large, lowerundergraduate courses as a primary area of focus. information technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 3 there are numerous papers which document usability testing of primo. prommann and zhang (2015) analyzed the efficiency of primo through hierarchical task analysis (hta). they counted the number of physical and cognitive steps necessary to get to records or full text of known items and concluded that primo is “a flexible discovery layer as it helps achieve many goals with minimum amount [sic] of steps.”7 although many of these studies articulate avenues of success in terms of user interaction with the discovery environment, there are also reports of difficulties in a variety of categories. students have problems with source retrieval, for example, understanding availability status terminology and labels, and using link resolvers and interlibrary loan.8 dalal et al. (2015) demonstrated that retrieving the full text of an article in a discovery environment is sometimes unintuitive for students and involves navigating multiple interfaces. 9 users also have issues using facets to find particular resource types or distinguishing between them. 10 while the study addressed in this paper does not directly address user difficulties with primo functionality, issues with source retrieval point to a plausible explanation for the few matches between the model search results and student paper bibliographies. it is possible students saw many of the same sources from the model searches in their results, but ultimately did not secure those sources because of the difficulties outlined above. in other words, some source selection choices are based mostly on availability, not as much on relevance. source relevancy is an active area of research for web-based discovery services, in terms of comparative studies to disciplinary subject databases. evelhoch and zebulin analyzed two years of usage data from both primo and a selection of subject databases, concluding that users have difficulty finding relevant sources in primo or they are not available. 11 based on users’ judgments, lee and chung, determined that ebsco discovery service was less effective than a set of education and library subject databases in terms of source relevance. 12 another study illustrated that while students preferred discovery environments, the articles they selected from the subject (indexing and abstracting) databases were more authoritative.13 finally, librarians are posited to believe that subject databases are superior to discovery environments in terms of the relevancy of search results and disciplinary coverage.14 conclusions about source relevancy are complicated by the fact that students infrequently look beyond a first page of results lists.15 researchers have also explored the idea of primo user satisfaction through the presence of relevant results. in one instance, using online questionnaires and in-person focus groups, researchers found users had a high level of satisfaction with their institution’s discovery environment, largely attributed to the quality of search results over ease of use.16 hamlett and georgas (2019) conducted a mixed-methods user experience study to understand student perceptions of relevancy in primo. this study found that participants believed primo to return relevant results (with an average score of 8.3 out of 10). however, some of the qualitative responses indicated that the keywords used did not actually yield relevant results. 17 many other methods and measures have been executed in determining the value and usefulness of primo. huurdeman, aamodt, and heggo analyzed a dataset of 50 popular queries in primo. they deemed a query successful if the first 10 results included the (likely) targeted resource and found that 58% of the queries from the popular searches dataset had been successful, while 20% were unsuccessful, and 22% could not be determined. their approach assumed there is one intended document per query and that the authors can surmise what it is.18 the research presented in the remainder of this article below is unique in that the authors explore user judgment of source relevance (satisfaction) as a function of whether sources in the model primo searches for their topics existed in the students’ papers’ bibliographies. information technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 4 methods research questions the impetus for this study was to understand the factors that play a role in establishing a framework to test the relevancy of results returned from primo. the authors attempted to answer the following questions: • how effective is primo at returning relevant results? • to what extent does faceting improve search results? • which search strategies are the most effective within the given framework? • how can the researchers refine the framework for future investigations into relevancy? • what are the implications of this study for end users? data collection the authors began with a sample of 100 randomly selected and anonymized research papers that were submitted to the roots of contemporary issues (rci) courses in fall 2018 and spring 2019 semesters. the study used a two-pronged approach to generate keywords for model primo search queries. for one approach, keywords were machine-generated via a word-vector generation process. for the other, keywords were human-generated by a student research assistant to approximate natural language queries. keywords and queries, machine a rapidminer (https://rapidminer.com/) word-vector generation process with term-frequency schema converted the research papers into keywords, which the authors then used to generate search queries. within the main routine, the process documents from files operator, rapidminer transformed the texts into lower case and tokenized the final papers according to non -letters. rapidminer then filtered the data by those tokens representing nouns and adjectives, removed english stop words, and filtered tokens by length, with a minimum of one character and maximum of 50 characters. the researchers then applied a snowball stemmer for english words and generated 20 n-grams per paper, each with a maximum length of four. table 1 illustrates the product of the word-vector generation process. throughout this example research paper, "trade” occurred 40 times, "slave” occurred 34 times, “slave” and “trade” occurred together 26 times, "africa” occurred 18 times, "impact” occurred 16 times, “african” occurred 11 times, and "peopl” occurred 10 times. table 1. example n-grams and frequency as retrieved from rapidminer n-gram number of occurrences trade 40 slave 34 slave_trade 26 africa 18 impact 16 african 11 peopl 10 ... ... https://rapidminer.com/ information technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 5 number of n-grams after compiling the data in rapidminer, the authors created a process to select those n-grams to use in the model primo search queries. huurdeman, aamodt, and heggo (2018) found that users included an average of 2.6 terms per query in their popular searches dataset.19 in a report by ex libris, stohn indicates that most topic-search queries contain five or fewer words.20 in order to investigate both ends of this spectrum, this study constructed short-length queries, consisting of two n-grams, and full-length queries, consisting of four n-grams, using the following rubric to help systematize the construction. rubric to select n-grams for shortand full-length queries pick terms that satisfy the following criteria: 1. n-grams that occur more frequently in a paper are preferred to those that occur less frequently. 2. if two n-grams appear to be structural derivatives of the same word (e.g., korea and korean), select the shortest n-gram and truncate it. 3. if one or more of the top terms appear in a later 2-gram, use the 2-gram as a phrase search. 4. ignore n-grams with repeating terms (e.g., south_africa_africa). 5. truncate all terms (using asterisk or question mark), except the first term of a phrase search, unless the first term is not a complete word (e.g., “busi* meeting*”). 6. for terms or phrases that end in truncated “i”, use the truncated version of the term and its truncated “y” counterpart, and combine both with an or operator (e.g., countri* or country*). 7. ignore all 3and 4-grams as they have a propensity to create nonsensical phrase searches (e.g., racism_polic_brutal). 8. if abbreviations are encountered, expand them for searching purposes (e.g., us is “united states”), except in cases where they are more commonly known by their abbreviation (e.g., ddt). 9. ignore results of contractions (e.g., ‘t) in case of a tie in the selection of an n-gram, sequence the following rules for selection: 1. preference proper nouns over other nouns and adjectives. if there are multiple proper nouns, preference place-name proper nouns over other proper nouns. 2. preference the n-gram that occurs in the greatest number of two or more n-grams later in the list. 3. preference longer words over shorter words. 4. group all the tied n-grams with a series of or statements. note: this may result in the selection of more than four total n-grams. referring to the example n-grams from table 1, an illustration of this method is shown in the following steps: 1. arrange terms from highest to lowest frequency. 2. select slave_trade as first n-gram, since “trade” and “slave” both occur in later n-gram. truncate to “slave trade*”. 3. select africa since it has the next greatest number of occurrences. combine africa with african since they are structural derivatives of one another. truncate to africa*. information technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 6 at this point, the first two selected n-grams—slave_trade and africa—become the keywords of the short-length query “slave trade*” and africa*. 4. select impact since it has the next greatest number of occurrences. truncate to impact*. 5. select peopl since it has the next greatest number of occurrences. truncate to peopl*. finally, the first four selected n-grams—slave_trade, africa, impact, and peopl—become the keywords of the full-length query “slave trade*” and africa* and impact* and peopl*. on average, after stop words and booleans were removed, the full-length queries in this study were 5.69 keywords long, while the short-length queries were 3.11 keywords long. keywords and queries, natural language in addition to the machine-oriented keyword process, the authors employed a student research assistant to create human-generated phrases, consisting of 3–10 words, which served as synopses for each of the 100 papers. this study then used these phrases as proxies for creating natural language search queries. for the same example research paper cited in table 1 above, this student created the summary phrase history and effects of the slave trade. this phrase in its entirety became the natural language query. on average, after stop words and booleans were removed, the natural language queries used in this study were 3.95 keywords long. search results using the three keyword-generation strategies outlined above, the authors constructed search queries and ran them against the ex libris’ primo search api endpoint. table 2 summarizes example result sets from the above short-length query, full-length query, and natural language query. for each of the keyword-generation strategies, the authors constructed search queries along four parameters: queries that used no faceting (open-ended), queries that faceted to articles only (articles), queries that faceted to books and ebooks only (books), and queries that faceted to newspaper articles only (newspapers). in all, there were 12 search-query constructions (three query types by four faceting modes) for fall 2018 and 12 for spring 2019. to construct a baseline for the search comparisons, the researchers designed the initial search to be open-ended. that is, the study assumed that patrons most often use the default, basic search functionality, with no facets selected. a segment of the rci instruction specifically encourages students to incorporate materials with resource types articles, books, and newspaper articles into their research papers. the authors therefore assumed that these students would most likely utilize facets corresponding to these resource types in their more specific queries and mirrored this behavior in the comparative searches. each primo search api returned titles for the top 50 results, moving beyond users’ usual search behavior in an effort to provide more flexibility to the initial steps of the relevancy framework. information technology and libraries june 2021 framework

against 60,000 citations retrieved from the wsu primo search api endpoint on july 24, 2020, as described previously in the methods section. to better account for the differing numbers of citations among resource types in the source data and to normalize reporting across query types and semesters, most results are presented as a percentage and referred to as the matching success rate. for example, the natural language query had six matches out of a possible 360 citations in the open-ended search for citations from the fall of 2018. the matching success rate of the open-ended search in the fall of 2018 therefore is calculated at 1.67% (see table 5). table 6 below shows the percentage results for short queries, and table 7 for full queries. for information about the raw source numbers and target data, please see the open science framework project site.21 when all query types and faceting modes are considered, the matching success rate almost uniformly increased from fall 2018 to spring 2019. the largest difference in matching success rate was observed in the full-query articles only search at 8.91% as shown in table 7. the open-ended search observed the smallest difference in positive movement and the anomaly of a diminishing success rate. across the natural language and full-query types the open-ended search exhibited the least amount of positive difference in success rate, at 1.04% and 0.26% respectively, and the short-query open-ended search had a small negative change in success rate at −0.36%. information technology and libraries june 2021 framework

four iterations, the researchers also note a raw count of matches which helps to determine how an overall search strategy is performing at finding matching citations. as the reader might expect, this metric includes a matching citation once across all four iterations of a search strategy. meaning, even if a source citation appears in both the open-ended search and the books only search, that source citation is only counted once for the purpose of this metric. for example, in the natural language query in fall 2018, six citations were matched in the openended search. four of the citations were articles and two were books. some of the matches in the articles and books searches were redundant to the open-ended search. considering only unique matches in the articles, books, and newspaper searches, the authors calculated the total number of unique matches. when the target searches were compared, the researchers matched two additional citations in the books only citations list. when the authors add the two additional matches, there were a total of eight unique citation matches across all iterations of the natural language search (open-ended search, books only, articles only, newspapers only). the total unique matches number and the corresponding success rate of the total unique matches for each search strategy is shown in table 8. information technology and libraries june

the percentage of matching citations that are new to the results list when limited to a certain resource type— matches added by faceting. meaning, what matching citations were not present in the open-ended search results but are then matched when the results list is reduced to only a single resource type. in table 9, the percentage of matches that are new and only to be found in a targeted search result varies greatly. between both semesters and among all search iterations, the smallest percentage of matches added by faceting is 14.29% and the largest is 83.33%. table 9. matches added

strategies the matching success rate across search strategies (natural, short, full) and iterations is a mixed result and does not allow for very useful comparison beyond descriptions of difference which are outlined in the comparison tables (tables 5–7). to better compare the search strategies as a whole, as opposed to how a particular iterative search performed relative to another open or targeted search, the researchers used a weighted success rate of the total unique matches from both semesters as the proxy for overall performance and the point of comparison among the three search strategies. the comparison of this weighted success rate shows no difference in overall success rate between the natural language query (4.11%) and the short query (4.11%). the search strategy that was demonstrably different in weighted success rate is the full query at a lagging 2.88%. see table 10 for comparison and calculation details. table 10. weighted success rate of total unique matches

how effective is primo at returning relevant results? according to the preliminary findings, primo is relatively ineffective at providing search results that match the citations used by the student researchers. the matching success rates of the openinformation technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 12 ended searches range from 0.56% to 3.33%. the possible reasons for these low numbers are numerous and varied; everything from students perhaps intending to use sources in the researchers’ auto-generated results lists, but unfortunately were unable to locate the full text, to the prevalence of finding open internet sources outside the discovery layer, to open-ended searches being flooded with rarely cited reference materials and very contemporary newspaper articles (see more about these ideas below). future research aims to understand more clearly which potential factors are present and to what degree they impact the matching success rates. to what extent does faceting improve search results? faceting within primo leads to better results, although the matching success rates are still more ineffective than not. the faceted searches contain the only matching success rates above ten percent: 10.10% (full query, articles only), 10.42% (short query, books only), and 11.46% (natural language query, books only). the data shows that the majority of unique matches found by the 2019 full-length and natural language search strategies occurs within the faceted searches (83.33% and 54.55%, respectively). it is interesting to note that these represent the two longer query strings, on average. future testing will reveal whether there is a relationship between query length and percentage of matches added by faceting. which search strategies are the most effective within the given framework? looking at the search strategies holistically, the researchers note that the total unique matches increased from fall 2018 to spring 2019 across all three query types. this increase was expected behavior, partially due to the fact that primo relevancy ranking algorithms assume that patrons prefer newer materials.22 the weighted success rate is an attempt to understand each search strategy’s performance over the 2018–2019 academic year, as opposed to comparing one semester to the other. from this metric, the consistency of the short-length query is equally effective as the more dynamic performance of the natural language query. the researchers are looking forward to adding more data to this metric to understand in which direction the average might move. how to refine the framework for future investigations into relevancy the most popular resource types used in the source citations were books, journal articles, web documents, and newspaper articles. together, these categories comprised approximately 93% of all resource types in both fall 2018 and spring 2019. however, not all areas were equally accessible within washington state university’s discovery layer configuration. the heavy reliance on web documents in the source citations was somewhat problematic, given the fact that web documents did not constitute a faceted resource type in wsu libraries’ primo prior to this study. therefore, the authors will need to better account for web documents in future testing. the assessment of newspaper articles also proved to be problematic, given their proclivity to inundate primo search results with numerous and recent documents. the sheer number of newspaper articles published and indexed every year in primo for general and introductory topics can dilute the pool of possible target citations greatly. for example, a scan of the matching newspaper articles reveals that 67% (4/6) were published in 2018. in future studies, the researchers will limit publication dates for target citations to the appropriate time period (e.g., an upper limit of may 2019 would be placed on publication dates for papers written in spring 2019) or collect data closer to the submission of research papers. in 11 out of 12 cases, matching success rates were better in spring 2019 than fall 2018, most likely due to recency. it is common for discovery environments, and true for the environment used in this study, to present content information technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 13 sorted by relevance and then publication date. therefore, the researchers expected to and did find an increased matching success rate closer to the date of testing, with the one exception of the short-length, open-ended search query. this anomaly led researchers to dig more deeply into the target citations to see if a cause could be determined. researchers found a larger than expected number of citations for resource types that are underrepresented in source citations. for example, the reference entry resource type surfaced prominently in the open-ended search for several of the queries, diluting the pool of target citations with entries that had little chance of appearing in the source citation lists. in one standout example, there were four separate reference entries titled simply “taiping rebellion.” the discovery environment gave preference to these four separate reference entries over other, more substantive works, that are more likely to be cited in an academic paper. the researchers surmise this is partly a function of the relevancy ranking algorithm that gives greater weight to matches in the title, author, and subject fields.23 depending on the search and the configuration of the discovery environment, it is possible that reference entries would push other results from books, articles, and newspaper resource types farther down the results list, making them less and less visible in an open-ended search for a given topic. this dilution of the target citations with resource types that are not emphasized or widely used in source citations is another area the researchers aim to isolate and examine in further rounds of testing. in addition to the source recency and particular source type issues explained above, the authors did not take into account source availability, nor where sources were found by students, which remains a confounding factor on matching success rate. subsequent studies will capture whether sources are present in the local deployment of primo during the time frame the students were conducting research. this issue will be further addressed and mitigated by analyzing urls provided within student source citations. implications of this study for end users the matching success rate in the open-ended search when compared to the type-limited searches leads to a discussion of how to define and present the default search of the discovery environment to best serve an academic population. more pointedly, it opens the discussion of what resource types to include within that default search to return the most relevant and useful results and not just the most results. in this case, the argument could be made that excluding several resource types (e.g., reference entries) would surface resources that are more likely to be cited in a researcher’s scholarship. based on the number of matches that were introduced by performing a faceted search, it is evident that researchers still need to utilize a search strategy which includes using search filters and limiters (prior to or following the initial search) and other search tactics in a discovery environment to return relevant results. the notion that an open-ended “one and done search,” for even the most introductory of topics, will be successful in retrieving many usable and citable resources in the first page or two of results is not supported by the results of this study. conclusions and next steps as the common adage goes, “it’s not what you say, it’s what you do.” in this study, the saying applies as the researchers move beyond what sources students think are relevant to the sources students ultimately use in their papers. the current slate of discovery environment research projects focuses largely on users’ affective connections to discovery environments, often information technology and libraries june 2021 framework for measuring relevancy in discovery environments | galbreath, merrill, and johnson 14 compared to other kinds of academic databases, and places users in temporary, hypothetical research scenarios in order to judge source relevance.24 in juxtaposition, the rci research project is a term-length (10–14 weeks) venture; students have a significant amount of time and the aid of a scaffolded set of assignments, to bolster their source relevance assessment skills and authority. methodologies which closely mirror the authentic experiences and curriculum of the students are those which arguably will provide a more accurate picture of the value of the discovery environment in an academic setting. the authors of this study took the first steps in building a relevancy rating system for discovery environments. to standardize their preliminary results, they generated four metrics: matching success rate, total unique matches, matches added by faceted search, and weighted success rate. while the results of this study do not allow the researchers to draw statistical conclusions regarding the dominance of one search strategy over another in returning relevant results, the frequencies showed a better match (success) rate with faceted than non-faceted searching. discovery environments are commonly advertised as providing an easy to use, one-stop location for academic research needs, but the reality is more complex. students need to engage these systems with multiple search refinements to find valuable materials. this investigation was also the initial attempt to create a machine-generated framework to test the relevancy of web-based discovery environment’s results. as the authors look to build upon this preliminary study, there are several avenues to pursue that will enhance the methodology of the framework. one avenue is a refinement of the boundaries of the testing framework. this boundary refinement includes a re-examination of the criteria for inclusion in both the source citations and the search results list. in the current study, all student citations were deemed viable regardless of whether the source citation was able to be verified and accessed. this led to the inclusion of citations of lecture notes and other such materials that are not generally expected to appear in a discovery environment. the authors will also re-examine the inclusion of newspapers and reference works in open-ended searching. these two resource types are large in number, are not indexed very well, and often do not have descriptive titles. a portion of the next round of research will be dedicated to comparative testing (a/b) of generally deployed discovery environment configurations. another avenue of exploration is determining where in the results list a citation appears, not just the binary positive or negative, and measuring any impact based on behavior of the search (i.e., search construction) or behavior and configuration of the discovery environment. refining the methodology of the current framework will result in fewer potentially confounding factors and allow librarians to regain an understanding of relevancy when it comes to teaching discovery layers to student researchers. these next steps will contribute to the overall picture concerning the value and efficacy of web-based discovery environments that is steadily taking shape. information technology

michael ridley (mridley@uoguelph.ca) is librarian, university of guelph. © 2022. abstract the field of explainable artificial intelligence (xai) advances techniques, processes, and strategies that provide explanations for the predictions, recommendations, and decisions of opaque and complex machine learning systems. increasingly academic libraries are providing library users with systems, services, and collections created and delivered by machine learning. academic libraries should adopt xai as a tool set to verify and validate these resources, and advocate for public policy regarding xai that serves libraries, the academy, and the public interest. introduction explainable artificial intelligence (xai) is a subfield of artificial intelligence (ai) that provides explanations for the predictions, recommendations, and decisions of intelligent systems.1 machine learning is rapidly becoming an integral part of academic libraries. xai is a set of techniques, processes, and strategies that libraries should adopt and advocate for to ensure that machine learning appropriately serves librarianship, the academy, and the public interest. knowingly or not, libraries acquire and provide access to systems, services, and collections infused and directed by machine learning methods, and library users are engaged in information behavior (e.g., seeking, using, managing) facilitated or augmented by machine learning. machine learning in library and information science (lis), as with many other fields, has become ubiquitous. however, this technology is often opaque and complex, yet consequential. there are significant concerns about bias, unfairness, and veracity.2 there are troubling questions about user agency and power imbalances.3 while lis has a long-standing interest in ai and intelligent information systems generally, 4 it has only recently turned its attention to xai and how it affects the field and how the field might influence it.5 xai is a critical lens through which to view machine learning in libraries. it is also a set of techniques, processes, and strategies essential to influencing and shaping this stil l emerging technology: research libraries have a unique and important opportunity to shape the development, deployment, and use of intelligent systems in a manner consistent with the values of scholarship and librarianship. the area of explainable artificial intelligence is only one component of this, but in many ways, it may be the most important.6 dismissing engagement with xai because it is “highly technical and impenetrable to those outside that community” is neither acceptable nor increasingly possible.7 artificial intelligence is the essential substrate of contemporary information systems and xai is a tool set for critical assessment and accountability. the details matter and must be understood if libraries are to have a place at the table as xai, and machine learning, evolves and further deepens its effect on lis. mailto:mridley@uoguelph.ca information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 2 this paper provides an overview of xai with key definitions, a historical context, and examples of xai techniques, strategies, and processes that form the basis of the field. it considers areas where xai and academic libraries intersect. the dual emphasis is on xai as a toolset for libraries to adopt and xai as an area for public policy advocacy. what is xai? xai is plagued by definitional problems.8 some definitions are focused solely and narrowly on the technical concepts while others focus only on the broad social and political dimensions. lacking “a theory of explainable ai, with a formal and universally agreed definition of what explanations are,”9 the fundamentals of this field are still being explored, often from different disciplinary perspectives.10 critical algorithm studies position machine learning as socio-techno-informational systems.11 as such, a definition of xai must encompass not just the techniques, as important and necessary as they are, but also the context within which xai operates. the us defense advanced research projects agency (darpa) description of xai captures the breadth and scope of the field. the purpose of xai is for ai systems to have “the ability to explain their rationale, characterize their strengths and weaknesses, and convey an understanding of how they will behave in the future” 12 and to “enable human users to understand, appropriately trust, and effectively manage the emerging generation of artificially intelligent partners.”13 xai is needed to: 1. generate trust, transparency, and understanding; 2. ensure compliance with regulations and legislation; 3. mitigate risk; 4. generate accountable, reliable, and sound models for justification; 5. minimize or mitigate bias, unfairness, and misinterpretation in model performance and interpretation; and 6. validate models and validate explanations generated by xai.14 xai consists of testable and unambiguous proofs, various verification and validation methods that assess influence and veracity, and authorizations that define requirements or mandate auditing within a public policy framework. xai is not a new consideration. explainability has been a preoccupation of computer science since the early days of expert systems in the late twentieth century.15 however, the 2018 introduction of the general data protection regulation (gdpr) by the european union (eu) shifted explainability from a purely technical issue to one with an additional and urgent focus on public policy.16 while the presence of a “right to explanation” in the gdpr is highly contested, 17 industry groups and jurisdictions beyond the eu recognized its evitability spurring an explosion in xai research and development.18 types of xai taxonomies of xai types are classified based on their scope and mechanism.19 local explanations interpret the decisions of a machine learning model used in a specific instance (i.e., involving data and context relevant to the circumstance). global explanations interpret the model more generally (i.e., involving all the training data and relevant contexts). in black-box or model-agnostic explanations, only the input and the output of the machine learning model are required while information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 3 white-box or model-specific explanations require more detailed information regarding the processing or design of the model. another way to categorize xai is as proofs, validations, and authorizations. proofs are testable, traceable, and unambiguous explanations demonstrable through causal links, logic statements, or transparent processes. typically, proofs are only available for ai systems that use “inherently interpretable” techniques such as rules, decisions trees, or linear regressions.20 validations are explanations that confirm the veracity of the ai system. these verifications occur through testing procedures, reproducibility, approximations and abstractions, and justifications. authorizations are explanations because of processes in which third parties provide some form of standard, ratification, prohibition, or audit. authorizations might pertain to the ai model, its operation in specific instances, or even the process by which the ai was created. they can be provided by professional groups, nongovernmental organizations, governments and government agencies, and third parties in the public and private sector. academic libraries can adopt proofs and validations as means to interrogate information systems and resources. this includes collections which are increasingly machine learning systems themselves or developed with machine learning methods. the recognition of “collections as data” is an important shift in this direction.21 where appropriate, proofs and validations should accompany content and systems derived from machine learning. libraries must also engage with xai as authorizations to assess the public policy implications that exist, are emergent, or are necessary. library advocacy is currently lacking in this area. the requirement for policy and governance frameworks is a reminder that machine learning is “far from being purely mechanistic, it is deeply, inescapably human”22 and that while complex and opaque “the ‘black box’ is full of people.”23 prerequisites to an xai strategy three questions are important for any xai strategy: • what constitutes a good explanation? • who is the explanation for? • how will the explanation be provided? explanations are context specific. the “goodness” of an explanation is dependent on the needs and objectives of the explainee (a user) and the explainer (an xai). following research from the fields of psychology and cognitive science, keil suggests five reasons for why someone wants an explanation: (1) to predict similar events in the future, (2) to diagnose, (3) to assess blame or guilt, (4) to justify or rationalize an action, and (5) for aesthetic pleasure.24 for most people, explanations need not be complete or even fully accurate.25 as a result, who the explanation is for is critical to a good explanation. different audiences have different priorities. system developers are primarily interested in performance explanations while clients focus on effectiveness or efficacy, professionals are concerned about veracity, and regulators are interested in policy implications. nonexpert, lay users of a system want explanations that build trust and provide accountability. information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 4 a good explanation is also affected by its presentation. there are temporal and format considerations. explanations can be provided or available in real time and continuously as the process occurs (hence partial explanations) or post hoc and in summary form. interactive explanations are widely preferred but are not always appropriate or actionable. 26 studies have compared textual, visual, and multimodal formats with differing results. familiar textual responses or simple visual explanations such as venn diagrams are often most effective for nonexpert users.27 drawing from philosophy, psychology, and cognitive science, miller recommends four approach es for xai.28 explanations are contrastive. when people want to know the “why” of something, “people do not ask why event p happened, but rather why event p happened instead of some event q.” explanations are selected. “humans are adept at selecting one or two causes from a sometimes infinite number of causes to be the explanation.” explanations are social. “they are a transfer of knowledge, presented as part of a conversation or interaction, and are thus presented relative to the explainer’s beliefs about the explainee’s beliefs.” finally, miller cautions against using probabilities and statistical relationships and encourages references to causes. burrell identifies three key barriers to explainability: concealment, the limited technical understanding of the user, and an incompatibility between the user (human) and algorithmic reasoning.29 while concealment is deliberate, it may or may not be justified. protecting ip and trade secrets is acceptable while obscuring processes to purposively deceive users is not. regulations are a tool to moderate the former and minimize the latter. the technical limitations of users and the incompatibility between users and algorithms suggest two remedies. first is enhancing algorithmic literacy. algorithmic literacy is a “a set of competencies that enables individuals to critically evaluate ai technologies; communicate and collaborate effectively with ai; and use ai as a tool online, at home, and in the workplace.”30 libraries have a key role in advancing algorithmic literacy in their communities.31 just as libraries championed information literacy through the promulgation of standards and principles, the provision of diverse educational programming, and the engagement of the broad academic community, so too can libraries be central to efforts to enhance algorithmic literacy. second is a requirement that xai must be sensitive to the abilities and needs of different users. a survey of the key challenges and research direction of xai identified 39 issues, including the need to understand and enhance the user experience, match xai to user expertise, and explain the competencies of ai systems to users.32 this is the essence of human-centered explainable ai (hcxai). among hcxai principles are the importance of context (regarding user objectives, decision consequences, timing, modality, and intended audience), the value of using hybrid explanation methods that complement and extend each other, and the power of contrastive examples and approaches.33 proofs and validations xai that provide proofs or validations can be adopted by libraries to assess and evaluate machine learning utilized in systems, services, and collections. since proofs pertain to already interpretable systems, the four examples provided focus on validations: feature audit, approximation and abstraction, reproducibility, and xai by ai. these techniques may require access to, or information about, the machine learning model. this would include such characteristics as the algorithms used, settings of the parameters and hyperparameters, optimization choices, and the training data. while all these may not be normally information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 5 available, designers of machine learning systems in consequential settings should expect to provide, indeed be required to provide, such access. similarly, vendors of library content or systems utilizing machine learning should make explanatory proofs and validations available for library inspection. feature audit feature audit is an explanatory strategy that attempts to reveal the key features (e.g., characteristics of the data or settings of the hyperparameters used to the differentiate data) that have a primary role in the prediction of the algorithm. by isolating these features, it is possible to explain the key components of the decision. feature audit is a standard technique of linear regression, but it is made more difficult in machine learning because of the complexity of the information space (e.g., billions of parameters and high dimensionality). there are various feature audit techniques34 but all of them are “decompositional” in that they attempt to reduce the work of the algorithm to its component parts and then use those results as an explanation.35 feature audit can highlight bias or inaccuracy by revealing incongruence between the data and the prediction. more advanced feature audit techniques (e.g., gradient feature auditing) recognize that features can indirectly influence other features and that these features are not easily detectable as separate, influential elements.36 this interaction among features challenges the strict decompositional approach to feature audit and will likely lead to an increased focus on the relational analysis among and between elements. approximation and abstraction approximation and abstraction are techniques that create a more simplified model to explain the more complex model.37 people seek and accept explanations that “satisfice”38 and are coherent with existing beliefs.39 this recognizes that “an explanation has greater power than an alternative if it makes what is being explained less surprising.”40 approaches such as “model distillation”41 or the “model agnostic” feature reduction of the local interpretable model-agnostic explanations (lime) tool create a simplified presentation of the algorithmic model.42 this approximation or abstraction may compromise accuracy, but it provides an accessible representation that enhances understandability. a different type of approximation or abstraction is a narrative of the machine learning processes utilized that provides sufficient documentation for a reader to act as an explanation of the outcomes. an exemplary case of this is lithium-ion batteries: a machine-generated summary of current research published by springer nature and written by beta writer, an ai or more accurately a suite of algorithms.43 a collaboration of machine learning and human editors, the full production cycle of the book is documented in the introduction.44 in lieu of being able to interrogate the system directly, this detailed account provides an explanation of the system allowing readers to assess the strengths, limitations, and confidence levels of the algorithmic processes and offers a model of what might be necessary for future ai generated texts.45 libraries can utilize this documentation in acquisition or licensing decisions and subsequently make it available as user guides when resources are added to the collection. reproducibility replication is a verification strategy fundamental to science. being able to independently reproduce results in different settings provides evidence of veracity and supports user trust. however, documented problems in reproducing machine learning studies have questioned the information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 6 generalizability of these approaches and undermined their explanatory capacity. for example, an analysis of text mining studies using machine learning for citation screening in the preparation of systemic reviews revealed a lack of key elements to enable replicability (e.g., access to research datasets, software environments used, randomization control, and lack of detail on new methods proposed or employed).46 in response, a “reproducibility challenge” was created by the international conference on learning representations (iclr) to validate 2018 conference submissions and has continued in subsequent meetings.47 more rigorous replication through the availability of all necessary components and the development of standards will be important to this type of verification.48 xai by ai the inherent complexity and opacity of unsupervised learning or reinforcement learning suggests, as xai researcher trevor darrell puts it, “the solution to explainable ai is more ai.”49 in this approach to explanation, oversight ai are positioned as intermediaries between an ai and its users: workers have supervisors; businesses have accountants; schoolteachers have principals. we suggest that the time has come to develop ai oversight systems (“ai guardians”) that will seek to ensure that the various smart machines will not stray from the guidelines their programmers have provided.50 while the prospect of ai guardians may be dystopic, oversight systems performing roles that validate, interrogate, and report are common in code checking tools. generative adversarial networks (gans) have been used to create counterfactual explanations of another machine learning model to enhance explainability.51 with strategic organizational and staffing changes to enhance capabilities, libraries can design and deploy such oversight or adversarial tools with objectives appropriate to the requirements and norms of libraries and the academy. authorization xai that results from authorizations is an area where public policy engagement is needed to ensure xai, and machine learning, are appropriately serving libraries, the academy, and the public at large. three examples are provided: codes and standards, regulation, and audit. codes and standards one approach to explanation, supported by the ai industry and professional organizations, are voluntary codes or standards that encourage explanatory capabilities. these nonbinding principles are a type of self-regulation and are widely promoted as a means of assurance.52 the association for computing machinery’s statement on algorithms highlights seven principles as guides to system design and use: awareness, access and redress, accountability, explanation, data provenance, auditability, validation, and testing. however, the language used is tentative and conditional. designers are “encouraged” to provide explanations and to “encourage” a means for interrogation and auditing “where harm is suspected” (i.e., a post hoc process). despite this, the statement concludes with a strong position on accountability if not explainability: “institutions should be held responsible for decisions made by the algorithms that they use, even if it is not feasible to explain in detail how the algorithms produce their results.”53 information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 7 unfortunately, the optimism for self-regulation in explainability is undercut by the poor experience with voluntary mechanisms regarding privacy protection.54 in addition, library associations, library system vendors, and scholarly publishers have been slow to endorse any codes or standards regarding explainability. regulation the most common recommendation for ai oversight and authorization to ensure explainability is the creation of a regulatory agency. specific suggestions include a “neutral data arbiter” with investigative powers like the us federal trade commission,55 a food and drug administration “for algorithms,”56 a standing “commission on artificial intelligence,”57 quasi-governmental agencies such as the council of europe,58 and a hybrid agency model combining certification and liability.59 such agencies would have legislated or delegated powers to investigate, certify, license, and arbitrate on matters relating to ai and algorithms, including their design, use, and effects. there are few calls for an international regulatory agency despite digitally porous national boundaries and the global reach of machine learning.60 that almost no such agencies have been created reveals the strength and influence of the large corporations responsible for developing and deploying most machine learning tools and systems.61 reports comparing regulatory approaches to ai among the european union, the united kingdom, the united states, and canada indicate significantly different approaches but with most proceeding with a “light touch” to avoid competitive disadvantages in a multitrillion dollar global marketplace.62 the introduction of the draft eu artificial intelligence act marks the first major jurisdiction to propose specific ai legislation.63 while the act is fulsome about high-risk ai, it is silent on any notion of “explainable” ai, preferring to focus on the less specific idea of “trustworthy artificial intelligence.” with this the eu appears to retreat from the idea of explainability in the gdpr. an exception to this inertia or backtracking is the development and use of algorithmic impact assessments in both governments and industry. these instruments help prospective users of an algorithmic decision-making system determine levels of explanatory requirements and standards to meet those requirements.64 canada has been a leader in this area with a protocol covering use of these systems in the federal government.65 some identify due process as a possible, if limited, remedy for explainability.66 however, a landmark us case suggests otherwise. in state v. loomis, regarding the use of compas, an algorithmic sentencing system, the court ruled on the role of explanation in due process:67 the wisconsin supreme court held that a trial court’s use of an algorithmic risk assessment in sentencing did not violate the defendant’s due process rights even though the methodology used to produce the assessment was disclosed neither to the court nor to the defendant.68 the petition of the loomis case to the us supreme court was denied, so a higher court ruling on this issue is unavailable.69 advocacy for regulations regarding explainability should be a central concern for libraries. without strong regulatory oversight requiring disclosure and accountability, machine learning information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 8 systems will remain black boxes and presence of these consequential systems in the lives of users will be obscured. audit a commonly recommended approach to ai oversight and explanation is third-party auditing.70 the use of audit and principles of auditing are widely accepted in a variety of areas. 71 in a library context, auditing of ai can be thought of as a reviewing process to achieve transparency or to determine product compliance. auditing is typically done after system implementation, but it can be accomplished at any stage. it is possible to audit design specifications, completed code, cognitive models, or periodic audits of specific decisions.72 the keys to successful audit oversight are clear audit goals and objectives (e.g., what is being audited and for what purpose), acknowledged expertise of the auditors, authority of the auditors to recommend, and authorization of the auditors to investigate. any such auditing responsibility for xai would require the trust of stakeholders such as ai designers, government regulators, industry representatives as well as users themselves. critics of the audit approach have focused on lack of auditor expertise, algorithmic complexity, and the need for approaches that assess the algorithmic system prior to its release. 73 while most audit recommendations assume a public agency in this role, an innovative suggestion is a crowdsourced audit (a form of audit study that involves the recruitment of testers to anonymously assess an algorithmic system; an xai form of the “secret shopper”).74 this approach resembles techniques used by consumer advocates and might indicate the rise of public activists into the xai arena. the complexity of algorithms suggests that a precondition for an audit is “auditability.”75 this would require that ai be designed in such a way that an audit is possible (i.e., inspectable in some manner) while, presumably, not impairing its predictive performance. sandvig et al. propose regulatory changes because “rather than regulating for transparency or misbehavior, we find this situation argues for ‘regulation toward auditability’.”76 auditing is not without its difficulties. there are no industry standards for algorithmic auditing.77 a high-profile development was the recent launch of orcaa (orcaarisk.com), an algorithmic auditing company started by cathy o’neil, a data scientist who has written extensively about the perils of uncontrolled algorithms.78 however, the legitimacy of third-party auditing has been criticized as lacking public transparency and the capacity to demand change.79 while libraries may not be able to create their own auditing capacity, whether collectively or individually, they are encouraged to engage with the emerging algorithmic auditing community to shape auditing practices appropriate for scholarly communication. xai as discovery while xai is primarily a means to validate and authorize machine learning systems, another use of xai is gaining attention. since xai can find new information latent in large and complex datasets, discovery is promoted as “one of the most important achievements of the entire algorithmic explainability project.”80 alkhateeb asks “can scientific discovery really be automated” while invoking the earlier work of swanson which mined the medical literature for new knowledge by connecting seemingly unrelated articles through search.81 an emerging reason for libraries to adopt xai may be as a powerful discovery tool. https://orcaarisk.com/ information technology and libraries june 2022 explainable artificial intelligence (xai) | ridley 9 conclusion our lives have become “algorithmically mediated”82 where we are “dependent on computational spectacles to see the world.”83 academic libraries are now sites where systems, services, and collections are increasingly shaped and provided by machine learning. the predictions, recommendations, and decisions of machine learning systems are powerful as well as consequential. however, “the danger is not so much in delegating cognitive tasks, but in distancing ourselves from—or in not knowing about—the nature and precise mechanisms of that delegation.”84 taddeo notes that “delegation without supervision characterises the presence of trust.”85 xai is an essential tool to build that trust. geoffrey hinton, a central figure in the development of machine learning,86 argues that requiring an explanation from an ai system would be “a complete disaster” and that trust and acceptance should be based on the system’s performance, not its explainability.87 this is consistent with the view of many that “if algorithms that cannot be easily explained consistently make better decisions in certain areas, then policymakers should not require an explanation.”88 both these views are at odds with the tenants of critical thought and assessment, and both challenge norms of algorithmic accountability. xai is a dual opportunity for libraries. on one hand, it is a set of techniques, processes, and strategies that enable the interrogation of the algorithmically driven resources that libraries provide to their users. on the other hand, it is a public policy arena where advocacy is necessary to promote and uphold the values of librarianship, the academy, and the public interest in the face of powerful new technologies. many disciplines have engaged with xai as machine learning has impacted their fields.89 xai has been called a “disruptive force” in lis,90 warranting the growing interest in how xai affects the field and how the field might influence it. information technology and libraries june 2022 explainable

today need targeted information services to ensure that their user communities have the information they need. this study aims to design, develop, implement, and evaluate a mobile application for academic library services at tarbiat modares university (tehran, iran). a four-stage process was utilized to accomplish this aim. in the first phase, relevant literature was reviewed to obtain appropriate data requirements for the app. a questionnaire was designed and administered to survey expert librarians on the most suitable data requirements. the second phase involved the design of the user interface and user experience with the assistance of experts, followed by the evaluation of the experience. the third phase involved the development of the app in the android studio environment using the java programming language, based on the requirements identified in the first and second phases. the app was then made available to the user community. finally, the app was evaluated in the fourth phase using a questionnaire tool. the researchers found this approach to application development to be both economical and effective in the context of a developing country. introduction academic libraries are recognized as essential institutions for providing scientific resources and facilitating access to the user community.1 considering the role of university libraries in providing guidance and quality information to satisfy users’ information needs, these libraries are considered one of the most important scientific, educational, and research information bases on any campus.2 university libraries support a wide variety of academic programs as part of their mission. therefore, in every university, the proper functioning of the library is crucial, and any type of tool that facilitates this function and adds to its richness is also important.3 the way these libraries provide services is also important. library services are provided to fulfill a library’s organizational mission and obligations to patrons.4 mobile services in the library are one of the most flexible types of library services.5 these services are not limited to one physical place or specific population and can meet the needs of a fluctuating service population.6 the goals and objectives of mobile library services are an integral part of the overall mission of the library

keshavarz, elango, rabajani, and ghorbi system.7 in this study, the authors designed, developed, and evaluated a mobile app for academic library services at tarbiat modares university. the app was designed to provide a range of academic library services to users, such as access to resources and information, as well as tools for searching and navigating the library’s collections. literature review past research has shown the effectiveness of different forms and methods of improving information access and dissemination in various organizations.8 our research aims to improve student access to information at tarbiat modares university.9 the goal of this research is to design and develop a mobile app to address the lack of a comprehensive information access system in the central library at tarbiat modares university. the field of research on information access and dissemination has a long history with many notable studies. the o’neill thesis highlighted the importance of establishing a relationship between the library and researchers’ information needs through customized profiles that include keywords and selected themes.10 horne and kristensen described a campuswide table of contents service at cornell university library, which aimed to improve the performance of the service for scholars.11 hossain and islam discussed traditional and electronic methods of information dissemination, emphasizing the importance of such services.12 de giusti et al. developed an ontology-based system to identify users’ information context, which allows librarians to develop users’ profiles beyond the information the users offer themselves.13 porcel et al. suggested a fuzzy logic method for the dissemination of research resources, which improves users’ access to the information they need and recommends specialized and supplementary research resources to users.14 this study intends to develop a mobile app specifically for students of tarbiat modares university to improve their access to information. we believe that students with access to this app, when it is developed, will access information better and faster. information access has been identified as a major challenge for developing countries with limited access to personal computers, weak technological infrastructure, and barriers to accessing information due to restrictive policies.15 this is particularly prevalent in some developing asian countries.16 iran, despite having a strong communication infrastructure, also faces challenges with access to information.17 the use of the internal internet (iran’s internet is heavily censored and monitored) is widespread, while access to the global internet is limited, resulting in shortcomings in accessing global and high-quality information.18 as a result, many organizations and government centers in iran rely on the internal internet for disseminating information.19 recent literature suggests that the status of information access in public and university libraries in iran is low, with traditional methods of information dissemination (i.e., card catalogs) still in use.20 however, studies have shown that university libraries in developing countries can play a significant role in human development by providing a noncommercial mechanism for distributing information on important societal topics such as health, agriculture, nutrition, and women ’s health.21 to achieve this, it is necessary to move beyond traditional university library services and adopt new technologies, such as smartphone apps.22 in developing countries, it is particularly important to strengthen people’s ability to access reliable and accurate information.23 methodology in this study, a thorough review of scholarly literature was conducted to identify the necessary requirements for developing a mobile app. a graphical abstract, represented in figure 1, outlines the project description. expert librarians were responsible for selecting the necessary information technology and libraries september 2023 design, development, implementation, and evaluation of a mobile application 3 saeidnia, kozak, lund, mannuru, keshavarz, elango, rabajani, and ghorbi requirements from the chosen features for the application. the design of the mobile app prototype was carried out with the assistance of it experts. the usability of the app was evaluated using two standard questionnaires. the following sections provide an in-depth examination of each phase of the app’s development. figure 1. graphical abstract of the research phases. first, we conducted a review of the literature to identify the data requirements for an app. with the data obtained, we designed a researcher-made questionnaire and used that to identify the most appropriate features and requirements. expert university librarians provided support during this phase. our second phase involved designing the user interface and user experience of the mobile app with the help of it experts. we used the heuristic method as well as jakob nielsen’s 10 general principles to evaluate the prototype. in the next phase, we developed the mobile app using the data obtained from the first and second phases. we released the mobile app to students after it had been developed. using sus and quis tools, we evaluate the usability of the mobile app in the final phase. first phase: identifying the data requirements the first phase of the study involved identifying the key features of a mobile app for information access and library finding. to do this, a review approach was used, partially following the prismascr guidelines.24 a search of various databases was conducted using keywords and keyphrases such as “academic libraries,” “mobile service,” “smartlibrary,” “library services,” “library,” “application,” “app,” “smartphone,” “mobile-based application,” “mobile-based app,” “mobile library service,” “mobile technology,” “mobile devices,” “mobile library,” and “m-library app.” inclusion criteria for the publications reviewed required that articles or reviews be original, available in full text, written in english, and about the subject of mobile-based information access and finding for academic libraries. based on the results of the review, a questionnaire was designed to validate the selected application options and features (see appendix a).25 the reliability and validity of the questionnaire were calculated and confirmed by experts in the field of librarianship and information science. the questionnaire was distributed to 16 participants via email and google forms, with the options scored on a scale of 1 to 5. ibm spss statistics software, version 19.0 was used to complete all statistical analyses. information technology and libraries september 2023 design, development, implementation, and evaluation of a mobile application 4 saeidnia, kozak, lund, mannuru, keshavarz, elango, rabajani, and ghorbi second phase: designing and evaluating the user experience in the design phase, the focus was on enhancing the user experience and feature list of the mobile app through online workshops with experts in information technology, informatics, user experience design, and android mobile app development. participants were invited to participate via social networks (e.g., instagram, facebook, and linkedin) from october 20–28, 2021, with the goal of enrolling as many experts as possible. ultimately, 14 experts participated in the design phase. to better understand the user experience flow, we used the balsamiq mockups tool (https://balsamiq.com/), a low-fidelity wireframing tool that is industry standard.26 the figma web application (https://figma.com/) was also used for prototyping the mobile app, a collaborative interface design tool that emphasizes user experience and interface design .27 once an alpha version of the prototype was accepted by the experts, it was evaluated using the heuristic method to identify areas for improvement before the development phase. five experts in user experience design and mobile app development were asked to evaluate the prototype using jakob nielsen’s 10 general principles of nielsen’s severity ranking scale, based on a five-point scale (see appendix b).28 third phase: developing and implementing the results obtained from the first and second phases of planning provided the knowledge to be used in the development phase, in which we developed a database using my structured query language (mysql) and a mobile app to assist with information access and finding using android studio. during this phase, students were recruited for our study through purposive sampling, and interested candidates contacted us through online registration after seeing th e recruitment posts on tarbiat modares university’s social networks. twenty-seven participants registered and used the app from november 10 to december 25, 2021, for at least 20 minutes per day. the app contained an initial guide and an about us section with a whatsapp group created for participants to ask the app’s creators any questions related to the study and the app. the app was updatable to resolve any technical issues. fourth phase: evaluating usability after the implementation phase, which ended on december 26, 2021, the usability of the information access and library finding app was evaluated using two standard questionnaires: the system usability scale (sus) and the questionnaire for user interaction satisfaction (quis).29 the quis, which contains six sections, was used to evaluate user satisfaction with specific aspects of the human-computer interface, while the sus, which includes 10 questions rated on a five-point likert scale, was used to obtain an overall impression of users’ subjective evaluations of the app (see appendix c). the data was analyzed using spss software version 22. results general characteristics this study identified the features of a mobile-based app for library finding and information access for an academic library in iran. the objective was achieved by retrieving 1,074 documents, eliminating duplicate records (n=193), and screening 881 records. using the inclusion and exclusion criteria, 12 articles were selected for further analysis (see appendix d for the twelve articles and the features chosen from each). figure 2 depicts how articles were chosen. https://balsamiq.com/ https://figma.com/ information technology and libraries september 2023 design, development, implementation, and evaluation of a

of orders for resources from other libraries (e.g., books, articles, etc.), as well as access to library news and recommendations. it starts with a registration and login process, where users must provide an email address, username, and password to create an account. once logged in, the user is taken to a menu page with options for ordering and tracking, search, recommendations, and library news. the user can then proceed to the order completion page and fill out the necessary fields to submit the order or access the order tracking page. the tracking page includes a progress bar that displays the status of the user’s order and an online chat section where the user can communicate with a librarian. the menu page also includes a search option and a suggestions feature to help users find information quickly. there are also two action bars on the menu page, one at the top and one at the bottom of the screen, which provide access to additional features such as messages, bookmarks, help, last read, notifications, and settings (see fig. 3). information technology and libraries september 2023 design, development, implementation, and evaluation of a mobile application 8 saeidnia,

the internet so that the users can register their accounts in the app. thus, the users were registered on the server and their registration ids were stored on the app server. mysql was used to design and develop the database, and android studio was used to develop the app. eventually, after a thorough consultation with librarian specialists and experienced it, a beta version of the sdi mobile app was developed (see fig. 4 and appendix e). figure 4. examples of pages from the mobile app sdi. information technology and libraries september 2023 design, development, implementation, and evaluation

= excellent = grade a. information technology and libraries september 2023 design, development, implementation, and evaluation of a mobile application 11 saeidnia, kozak, lund, mannuru, keshavarz, elango, rabajani, and ghorbi discussion the results of the first phase of our study indicate that 55 out of 65 identified items received a mean of 2.5 or higher from the statistical population’s perspective. in the “access feature” category, items such as 24/7 access (4.71 mean) and access to books/information (4.41 mean) were highly rated. the “search feature” category saw high usage of the catalog search (4.33 mean) and metasearch (4.12 mean) features. a well-designed application allows for easy catalog searches, as evidenced by a survey of university students who had a positive understanding of using mobile-based apps to access the library catalog.31 the catalog search feature was identified as one of the most important features of library applications.32 in the “sending feature” category, the highest means were received by the ability to send files (text and image) and hyperlinks (4.65 and 4.32, respectively). these features are considered practical and important for academic use, as discussed in previous studies on the use of wechat and other social media in academic libraries .33 academic library applications often feature a recommender system, which utilizes user behavior to suggest appropriate items such as journals, books, and tutorials.34 studies on designing and evaluating academic library applications have also incorporated features such as new book, ejournal, and event recommendations.35 the “recommend feature” category saw the highest mean for e-journals (4.91). other methods, such as sms, have been used by academic libraries to send messages such as news announcements and event reminders, but in-app notification systems are considered more efficient and cost-effective.36 our study also found that participants gave the highest ratings to item due date reminders and renewal requests in the “notification feature” category (4.47 and 4.42 mean, respectively).37 finally, the “other features” category saw high ratings for the ability to use optical character recognition (ocr) to automatically detect text in document images and convert them into searchable and editable text (4.81 mean).38 this capability can assist students in discovering library resources through scanning, as shown in a study aimed at designing an ocr-capable app for students.39 based on the findings from the second phase, the experts determined that the design of the use r flow for the library mobile app should prioritize simplicity and ease of use. the online workshop discussed the technical and data requirements for the app and used the balsamiq mockups software to create a user experience flow. these findings are crucial for the prototype design and user interface of the app. additionally, the study addressed the importance of considering user experience and social justice in the design of software services, which has been recognized as a human rights issue by some scholars.40 users generally had a positive opinion of the library mobile app, finding it easy to use and well organized. the app received high scores in screen factors and display organization with a mean of six or above. the “terminology and system information” section of the app also received positive evaluations with a median higher than five in its options range of 4–9. additionally, features such as the ability to adapt to changing conditions, remember and take shortcuts, and provide helpful messages were positively evaluated, with means above six in the range of 5–9. error prevention and rectification were also considered important and positively evaluated. this study has some limitations, such as limited database access for the developers and the app being available only for android users, which excluded ios users. additionally, while the search for data elements and requirements in the first phase was broad, it was not as comprehensive as desired, which may have limited the scope of the study. furthermore, the sample size of the statistical population may not be representative of the entire population of university students information technology and libraries september 2023 design, development, implementation, and evaluation of a mobile application 12 saeidnia, kozak, lund, mannuru, keshavarz, elango, rabajani, and ghorbi and their perceptions of library mobile apps. despite these limitations, the study presents a comprehensive and realistic approach to the development of a mobile app for university libraries. this could be useful for app developers and managers of university libraries in creating a mobile app for their own libraries. conclusion this study aimed to design, develop, implement, and evaluate a mobile application for academic library services at tarbiat modares university in tehran, iran. through a methodological design, the research team reviewed relevant literature, surveyed expert librarians on data requirements, designed the user interface and user experience, developed the app using the android studio environment and java programming language, made it available to the user community, and finally evaluated it using a questionnaire tool. the results showed that the app was able to effectively provide a range of academic library services to users, such as access to resources and information, as well as tools for searching and navigating the library’s collections. furthermore, the study highlights the importance of involving experts in the design and evaluation process of a mobile app, as well as the use of software related to user interface design and user experience to ensure a more professional design. this app will be a unique offering in tarbiat modares university’s information environment, which will be beneficial for student and faculty’s academic and information needs.

(reading his or her name in romanized form is just as difficult for someone who knows arabic as reading your name when it's written in arabic. ) the new cataloging rules also specify that names and titles in notes be given in their original script, aacr2 l. 7 a.3. technological advances have made it possible to provide many, if not all , nonroman alphabets in machinereadable cataloging records. oclc and rlin are in the process of enhancing their systems so they can handle some nonroman writing systems. the library of congress has entered into a cooperative agreement with rlin for the development and use of an augmented rlin system for east asian (i.e., chinese, japanese, and korean) bibliographic data. although the library itself will not be creating and distributing marc records with nonroman characters in the near term , the goal of this proposal is to define how these data can be included now so others can do so soon. the technique known as an escape sequence announces that the codes which follow will represent letters in a specific different alphabet instead of the roman letters the codes would otherwise stand for. 2. principles the following principles will govern inclusion of other alphabets in marc records. note that these deal only with the marc communications format record, not the details of its processing-keying, sorting, display, etc.-by any bibliographic agency or utility. these principles are a slightly revised version of ones reviewed and approved in principle by the marbi character set committee in 1976. the earlier version was also distributed that year as working paper n77 of iso tc46/sc4/ wgi. (1) standard character sets should be used when available. (2) standard escape sequences should be used when available. (3) escape sequences should be used only when needed. (4) escape sequences are locking within a subfield but revert at any delimiter or field or record terminator code. example: (for demonstration purposes only, ec represents escape to cyrillic and ea escape to ascii) 245 10$aecrussian title proper :$becrussian subtitle. f not 245 10$aecrussian title proper :ea$becrussian subtitle. eaf and not 245 10$aecrussian title proper :$brussian subtitle. f (5) records which contain an escape sequence will also contain a special field which specifies what unusual character sets are present. 3. implementation the following will be done to realize these principles. • the ala character set will be redefined-see table 1. • a new character sets present field will be defined. • details of application such as distribution, filing indicator values, etc., will be defined. 3.1 discussionala character set a character set is a list of characters with the code used to represent each one. using this definition , the ala character set as given in appendixes iii.b and iii.c of marc formats for bibliographic data actually consists of eight character sets. (1) ascii and ala diacritics and special characters with their eight-bit code. (2) superscript zero to nine, plus, minus, open and close parentheses with their eight-bit code. table 1. proposed revised ala character set ~ p ~ p p p p i p p i p p p i i p i p p p i p i p i i p ~ i i i i ~ ~ ~ i p ~ i i ~ i p i p i i i i p p i i p i i i i p i i i i 4 3 2 i bits p i 2 3 4 ~ 6 7 r 9 10 ii 12 13 14 , 'i p i p i 2 nul ole sp soh dci ! fstx dc2 . etx dc3 " eot dc4 s enq nak " ack syn & bel !::to os can i ht em i lp sub vt f:sc + ff fs cr os , so ns , s l us' i ~ p l p 9 i i i i p p p i p i 3 ~ ~ . p @ p i a q 2 b r 3 c s 4 i> t ~ e u 6 p v 7 g w 8 h x !i i y j z ; k i < 1. \ m i > n ' 1 0 i ascii 6 • b c d c r • h ; j k i m n 0 reports and working papers 211 (3) subscript zero to nine, plus, minus, open and close parentheses with their eight-bit code. (4) greek lowercase alpha, beta, and gamma with their eight-bit code. (5-8) the same characters with their sixbit codes. the six-bit character sets are used to distribute marc records on seven-track tapes. there are very few subscribers. it is unlikely that a method can be devised for distribution of nonroman character sets records on such tapes. the present seven-track subscribers should be asked if they know of any way to do so. if they do not, the alternatives are to cease distribution of seven-track tapes entirely or limit them to those records containing only roman alphabet characters-those without a character sets present field. in the latter case, they should pay proportionately less for their subscription. the present four eight-bit character sets and their escape sequences do not conform to present standards. the present standards did not exist when the character sets were being defined. to avoid creating and distributing records containing both standard and nonstandard character sets and stanp p i i i i p p i i p p p i p i 7 8 9 . p q r ' l u ,. w x y , i' : i' -. del l i i /i p ~ i i i i i i p p i i p i p i ii p ~~. i i 10 ii 12 13 · u 0 l i l ' e • < 2 0 d ' j .. p ~ 4 4 . ;e • 5 s u <e .. 6 -, " 7 ' . . 8 .. < ~ ( 9 . 411 b + . ~ :!: r -0 " ( ~ lf u i ) ~ . a y . proposed change d ala extension of ascii i hb 7 i 6t ~) s 212 journal of library automation vol. 14/3 september 1981 dard and nonstandard escape sequences, the ala character set should be redefined. this change will be much less traumatic than it sounds. no new characters will be added; only the codes used to represent subscript, superscript, and greek characters will be changed. these characters were found in the title field of 8.59 out of 1.1 million records. if, as seems plausible, most or all marc subscribers translate tapes into their own character set codes as a first step and for communication translate from their own codes into the ala character set as the last step before distribution, only these two programs would need to be changed. the proposed redefined ala character set is shown in table 1. on it, columns two through seven are the american standard code for information interchange (ascii) which is a recognized standard with a registered escape sequence. columns ten through fifteen are the ala extension of ascii with special characters and the three greek letters in columns ten and eleven, superscripts in column twelve, subscripts in thirteen, and diacritics in columns fourteen and fifteen. (it should be noted that six ascii codes will not occur in marc records: codes 5/14 circumflex, 5/15 underline, 6/0 grave, and 7/ 14 tilde are redundant with the codes for these diacritics in columns fourteen and fifteen; codes 7 i 11 left brace and 7/13 right brace never occur because these characters do not occur in bibliographic data. no change in this practice is proposed. it is the fact that these last two codes are used in some nonroman alphabet standard character sets that makes nonroman six-bit codes impossible.) the ala extension of ascii is not an official standard now; it does not have an escape sequence yet. in addition to the ala extension of ascii, there is a draft international standard extended latin alphabet character set for bibliographic use-iso dis 5426 (table 2). while both sets are identical in purpose, they differ in the characters they contain and the codes used to represent them. the abacus group has agreed that iso 5426 be used for international distribution of marc records among the bibliographic agencies they represent once it is an approved international standard, cf. lc information bulletin, november 16, 1979, p. 475. the library will, however, continue to use the ala extension for u.s. distribution. some of the characters only on the iso set could be added to the ala extension without affecting existing records. an ansi z39 subcommittee has been established to consider this possibility. while some changes may be desirable to the ala character repertoire, it is important that this issue not delay the separate matter of providing for inclusion of nonroman alphabets in marc. 3.2 discussion-escape sequence for purposes of this discussion, escape sequences are defined as a combination of three characters. (see table 3.) the first is an escape character, hex 1111. the second character specifies which codes are having different characters assigned to them, those in columns 27 or those in columns 10-15. the third character defines what characters are being assigned to these codes, e.g., cyrillic, greek, etc. this is a greatly simplified explanation of the escape sequence standards, iso 2022 and ansi x3.41. (both are in the process of revision.) these standards provide for two types of escape sequences: public ones which reference registered character sets, and private ones for unregistered character sets. while the meaning of the latter is governed by an agreement between the sender and the receiver, they are in conformity with the standard. until the ala extension of ascii has a registered escape sequence, such a "private" escape sequence could be defined for it in the character set appendix and used. the second character of an escape sequence which changes the meaning of the codes in columns 2-7 contains either an open parenthesis, hex 2/8, or a less than sign, hex 2/12. the second character of an escape sequence which changes the meaning of the codes in columns 10-15 contains either a close parenthesis, hex 2/9, or an equal sign, hex 2/13. the third character of escape sequences for certain registered character sets has been defined as follows: table 2. extended latin alphabet character set ii . : 0 0 0 i ~ 0 lb71b61bs b4 b3 b2 bt 1\ow set ascii bits russian (1967 cost standard) (table 3) iso greek rso extended cyrillic (table3) 0 0 0 0 0 0 0 0 1 1 0 0 1 0 2 0 0 l 1 3 0 1 0 0 4 0 l 0 1 5 0 1 1 0 6 0 1 1 1 7 1 0 0 0 8 1 0 0 1 9 1 0 l 0 10 1 0 1 l 11 1 l 0 0 12 l 1 0 1 13 1 1 1 0 14 1 1 1 1 15 code registration applied for, code pending 5/8, uppercase x 517, uppercase w 0 0 1 the sixteen codes in column three can be used to designate sixteen different "private" character sets. in marc records, ascii and russian would be assigned to columns 2-7, while greek and the extended cyrillic (and the ala extension of ascii) would be assigned to columns 10-15. 1 reports and working papers 213 10 0 1 1 11 l 1 1 0 0 1 1 0 1 0 1 0 1 2 3 4 5 6 7 . 7 ) . ... i l ie ae " -[) ct " . .j £ a 0 1.1 s ~ 0 ¥ ~ 1 t .t u u ij 9 . .. i ii .. _t. .r . . .. ¢ = ¢ .. .. 0 <e i <e « >> . b "' b * . p p © i ii r ® ii j 1 ® l " '-../ escape sequences would be given where needed in data fields. if necessary, it is permissible to embed escape sequences within a word. for example, a latin diacritic might be needed with an extended cyrillic letter to represent a letter in one of the nonslavic languages of central asia which uses the cyrillic alphabet. in addition to escape sequences for nonroman alphabets described above in which one code stands for one letter, the escape standards also define escape sequence procedures for changing to multiple byte character sets. because the ideographic writing 214 journal of library automation vol. 14/3 september 1981 table 3. escape sequence character set p p p p p p p 1 p p 1 p ~ ~ 1 1 u i p p p i p 1 p i 1 p p 1 i 1 i p p u 1 u u 1 i ~ 1 p i ~ i i i i p u i i q i i i i p i 1 i i ·i 3 2 i jilts g 1 2 j 4 r. 6 7 8 9 ill 11 12 ij (.1 1$ fl ~ ~ u ~ p 1 p 1 ~ p q p 1 1 p i 2 3 sp p ! 1 " 2 # j ll 4 \\ $ & 6 7 i 8 i 9 : • : < > i ? l ~ i i i g g i p i ~ 4 !o g 10 n 10 a « a 15 p !j 1.1 c ll a t .n e >' e <!> "' <l> r • r " • x u .. lo( -,, 3 ~ k w " j1 . n ... u1 m k ~ ll 0 . 0 ~ i i l i i u g p u i 1 p ~ i 1 u 1 ~ 1 ~ i ~ 7 8 9 10 11 12 n r .!l ~ p r c c t ~ y s lk j b 'i b j bl "' 3 ,_ ill ii 3 " ul y 'l ,, ,, i i p 1 13 -t 9 v ..

(since aacr2 says to give the title in the original script "wherever practicable," the library could be said to be obligated to do so.) in such an event the local record could have all the authoritative library of congress access points. to keep this record current when the library of congress record is revised and redistributed, it would be necessary to carry the lc control number in the local record . most automated systems are hypersensitive to the presence of two records with the same control number. the two records can be easily distinguished: in the library of congress record, the modified record byte in field 008 will be set to "o" and it will not have any 066, character sets present field. a comparison of oclc, rlg/rlin, and wln university of oregon library the

technology use. children’s librarians have a unique role to play in guiding the technology use of children and families, yet little is known about how public library programs facilitate children’s digital literacy. this study sought to uncover librarians’ purposes for using technology in programs with young children as well as the supporting factors and barriers they encountered in attempting to do so. findings reveal 10 purposes for integrating technology into public library storytime programs and 15 factors across four dimensions that facilitate and/or inhibit its inclusion. if librarians are to embrace the media mentor role with confidence and the necessary knowledge and skills required of the task, much greater attention should be devoted to the responsibility and more support in the way of professional development and resources is necessary. introduction technology use is widespread in the lives of children and families. from a very early age, children in highly developed countries across the world regularly interact with technology and data from device trackers substantiate parental reports.1 nearly all families have access to one or more mobile devices, and nearly three-fourths of children in the united states begin some form of digital engagement, primarily television viewing, before age three.2 prior to formal schooling, children (ages two to four) in highly developed countries tend to use a device with a screen for about two and a half hours per day on average.3 differences in screen use by income level and race are significant, with children from lowerincome families and children of color spending more time on electronic devices than children from higher-income families and children who are white. though most parents do allow their children to use technology, many voice some concerns about their children’s well-being, particularly regarding privacy as well as the content of the media.4 yet, young children’s digital activity can be beneficial, particularly when the technology is designed to foster active, meaningful engagement and when it facilitates social interaction.5 in light of children’s usage and parents’ concerns, librarians in public libraries have a unique role to play in this information realm. not only can librarians provide access to technology and recommended resources but they can also provide guidance in how to use technology to contribute to children’s learning, especially in the areas of reading, information literacy, and academic concepts.6 yet, little is known about whether librarians actually facilitate children’s digital literacy through integration of technology into programs, and this dearth of empirical mailto:maria.cahill@uky.edu mailto:erin.ingram@chpl.org mailto:soohyung.joo@uky.edu information technology and libraries june 2023 technology integration in storytime programs 2 cahill, ingram, and joo evidence is highlighted in the association of library services to children (alsc) research agenda.7 storytime, as a program attended by both children and caregivers, can be used as a time for children’s librarians to integrate technology for the purposes of modeling and explaining how various electronic tools might be beneficial for young children.8 due to this potential, it is important to understand how and why children’s librarians are—or are not—integrating technology into storytime programs. previous studies of technology use in children’s programs and storytimes internationally, there have been few investigations of technology integration within library programs for young children. within the united states, two survey studies, both commissio ned by alsc, sought to capture the use of technology in youth programming.9 the initial survey launched in 2014 and the follow-up survey in 2018. respondents to these surveys reported that the types of devices used most often in libraries were proprietary institutional devices, digital tablets, tangible tech such as squishy circuits that allow children to build electrical circuits with play dough, and programmable tech such as cubetto, a wooden robot toy.10 additionally, more than half of respondents working in medium and large libraries and more than 45% of those working in small libraries indicated using digital devices during storytimes.11 conversely, a comprehensive study of programming for young children in public libraries, which included observations, concluded that, “while many libraries offer families a place to use computers and other digital resources together, few libraries actively promote the use of technology during their programming.”12 notably, neither the 2014 nor 2018 alsc survey included questions about the types of technology used in storytimes, nor were respondents asked to explain their thoughts on why or how technology was or was not included in storytime.13 a study conducted in aotearoa new zealand collected data about technology use in storytime in three phases: a survey of 25 children’s librarians, interviews with librarians in nine libraries, and a survey of 28 caregivers who attend a library storytime with a young child.14 slightly more than a quarter of the librarians responding to the survey reported incorporating digital technology such as tablets or e-books into storytime programs. the most common rationale for technology use in storytime was to educate caregivers. other reasons included for the novelty of it and to promote accessibility and the aims of library services. interviewees explained that they used technology in storytime to show caregivers the availability of high-quality digital media such as e-books and educational apps, with one likening the use and recommendation of digital media to librarians’ traditional role as recommenders of storybooks (i.e., readers’ advisory services). conversely, one interviewee expressed reservations about using technology for fear that children would be distracted from the content of the story. the majority of caregiver respondents who had attended a storytime with digital technology reported enjoying the experience. however, those who had never attended a storytime with technology were apprehensive about doing so. technology best practices: joint media engagement and media mentorship recent scholarship encourages children’s librarians to use their expertise and experience to evaluate and recommend technology and new media resources as well as to model for adults how to interact with children as they use technology.15 for example, librarians can promote joint media engagement during storytimes both by modeling the practice and by directly explaining it to the adults in attendance. using technology during storytime can be seen as modeling modern literacy practices, just as reading print books has modeled literacy practices in traditional storytimes since the 1940s .16 information technology and libraries june 2023 technology integration in storytime programs 3 cahill, ingram, and joo alsc instructs youth services librarians to act as media mentors, a role that means they will assist caregivers in choosing and using technology by researching new technology and by modeling technology use, such as joint media engagement, for caregivers in programs such as storytimes.17 media mentorship is seen as an extension of how youth services librarians have traditionally been called upon to meet the needs of caregivers and children with their knowledge of child development and ability to facilitate caregivers’ information seeking.18 while alsc encourages media mentorship, the extent to which children’s librarians have embraced this role is unclear in professional research. findings from prior surveys and interviews with storytime providers suggest that librarians are regularly integrating technology into programs while observations of library programs suggest otherwise.19 further, goulding and colleagues found that while many librarians were comfortable recommending technology such as apps, it was unclear whether or not they were modeling its use during storytimes.20 study objectives the overarching research question of this study is “how do storytime providers view the integration of technology into storytime programs?” the following three research questions guide this study. 1. what are the purposes for using technology in storytimes? 2. what are factors associated with adopting technology in storytimes? 3. what are barriers to integrating technology in storytimes? method participants as part of a larger institute of museum and library services (imls)-funded, multistate study that was approved by the university of kentucky institutional review board (irb number 42829), researchers conducted semi-structured interviews with 34 library staff who facilitate storytime programs at public libraries serving urban, suburban, and rural communities across kentucky, ohio, and indiana.21 interviewees were not asked to identify their race or ethnicity. thirty-two identified as female and two as male. all but one of the participants (97%) had earned a college degree, but only 13 (38.2%) held a master’s degree from a library and information science (lis) program, while another two were enrolled in an lis master’s degree program when the interviews occurred. the majority of participants (57.1%) had five years or more of experience in children’s library services. the participants will be referred to as “storytime providers.” procedure the interviews were conducted by one member of the research team. other members of the team created written transcripts from recordings of the interviews. for the study reported in this paper, researchers focused on participants’ answers to the interview question “what place, if any, does technology or digital media have in a quality storytime program?” an open coding method was used to organize participants’ statements within three categories: purposes underlying technology use, factors associated with technology adoption, and barriers to technology integration. three researchers conducted open coding independently and came up with the initial set of coding results. then, the researchers discussed the coding results multiple times to assess the relevance of the coded constructs, refine operational definitions, and select one representative quote for each code. interviewees were assigned a number between 1 and 34 to eliminate identifying information. information technology and libraries june 2023 technology integration in storytime programs 4 cahill, ingram, and joo results what are the purposes for using technology in storytimes? to find answers to this research question, the researchers coded statements related to how or why interviewees used or wanted to use technology in storytime programs. we identified 10 specific purposes, formed operational definitions for each, and chose one representative quote (table 1). although most purposes had statements from more than one interviewee associated with them, we collaborated to choose one example due to space constraints. researchers determined that the purposes for technology use could be divided into two categories: experiential and learning. experiential purposes are those for which technology is used to create a positive, engaging experience for child and/or adult participants. learning purposes are those for which technology use is intended to help child and/or adult participants learn. what are factors associated with adopting technology in storytimes? to answer the second research question, researchers looked for statements explaining the reasons or causes for storytime providers using or wanting to use technology in their storytime programs. these would be factors that facilitate technology adoption. researchers coded statements independently and then discussed results multiple times to verify relevance and consolidate categories into 15 factors in four dimensions: storytime provider, participant, library system, and content. though many factors had more than one corresponding statement from participants, we chose one representative quote for each. results are presented in table 2. what are barriers to integrating technology in storytimes? to answer this question, researchers independently reviewed responses, looking for statements related to why storytime providers did not or did not wish to use technology during storytime. after individual coding, we collaborated to verify relevance, refine definitions of the 15 identified barriers, and choose representative quotes. the results are presented in table 3. researchers found that three of the dimensions created for factors that lead to techno logy adoption could also be applied to barriers to technology integration: storytime provider, participant, and library system. information technology and libraries june 2023 technology integration in storytime programs 5 cahill, ingram, and joo table 1. purposes for using technology in storytimes category purpose operational definition representative quote experiential accommodating large groups technology is used to enable a large group to view books/materials 2: “i had this huge group of kids. and i took them to our red room and did a story on our big screen. you know, through tumblebooks.” children’s enjoyment provider incorporates media or technology because children enjoy it 14: “and then as far as, um, sometimes, um, we’ll have, like, at the end of a storytime, we may have a little short, um, like nonfiction or sign language or if we were doing something on the alphabet, maybe i would throw in a little dvd and give them popcorn for the end of storytime and things like that and i think that they really enjoy that. it is important to integrate that in.” facilitating adult participation provider uses technology to display the words to songs to facilitate adult participation 12: “the closest thing i would say, i use a powerpoint that has the words on it for the parents to be able to follow along, um, or for the kids if they can pick out some of the letters or start to read, even some of the older ones.” facilitating movements technology is used to facilitate movements or dancing 19: “in addition to our singing, just to give, you know, to change it up a little bit. so, they can hear the music. we clap rhythms. so, we use that a lot.” playing songs/music technology is used to play songs or music 13: “we have a sound system that i love, with surround sound. we always do our last song with, you know, that, and i’ve been fortunate that it’s worked all the time.” information technology and libraries june 2023 technology integration in storytime programs 6 cahill, ingram, and joo category purpose operational definition representative quote sound effects technology is used to create a sound or voice 17: “one of the better things that i’ve done, that i like to do, is, i like to use animal sounds. i’ll research or pull up a list of sounds on youtube or whatever and have the kids listen to them. i think that’s always been a fun way to work in a little bit of technology without taking out all of the flow.” visual aids technology is used to support children’s visual experience 24: “and, like, it gives the kids a visual. and i feel like sometimes, if we could give them a better visual, they might be more engaged.” learning support for adult-child interaction technology is used to support adult-child interaction 1: “if you’re actually sitting down with your child, looking at it together, it’s a lot more effective and the child is getting a lot more out of it versus just sitting them in front of it and expecting to teach something to the child.” teaching caregivers technology is integrated to model for caregivers 11: “i think it’s important to share with parents really good e-resources, such as, like, apps. and books and stuff. so, that, i think it’s very important…. i have, like, when i have like a screen, a projector screen, maybe when the book i picked for the storytime was an e-book that they could get through the library, and kind of, you know, advertise that resource, and then we would, we would read the e-book, you know, from the projector. so i’ve done, like, e-books and stuff.” teaching concepts technology is used to present letters, words, numbers, shapes, sign language, colors, or coding skills, to children 22: “…. all these different color songs, um, and they’re actually just on youtube…. so that is one way that we’ve been incorporating technology, um, is with those color songs because it spells it out for them. they can see the word, it’s a familiar tune, and it helps them, you know, at least be able to sing, sing the song.” information technology and libraries june 2023 technology integration in storytime programs 7 cahill, ingram, and joo table 2. factors associated with adopting technology in storytimes dimension factor operational definition representative quotes storytime provider awareness provider is aware of the tool/technology available for storytime 1: “i’m aware of all kinds of apps that are out there and of course the ebooks.” familiarity provider feels comfortable with the technology and with integrating the technology into programs 1: “i feel like it’s going to be effective if it’s what you’re comfortable with and you’re excited about. because that will come through when you actually provide the storytime.” choice of provider ultimately it is up to the provider to choose to integrate technology or not 1: “i think it all depends on the provider.” provider’s philosophy and approach how the provider views storytime and its purpose influences technology integration 1: “everyone has their own, unique storytime philosophy and the way that they approach planning storytimes…. so, really, a lot of it is just ... theory of how you want to approach it since there’s so many options out there.” reaction/success with initial attempt if the provider tried technology integration, the success or failure of that initial attempt influences subsequent attempts 2: “it went over really well.” information technology and libraries june 2023 technology integration in storytime programs 8 cahill, ingram, and joo dimension factor operational definition representative quotes research base provider is aware of research to support integration of technology 1: “... it’s kind of what the research is saying with parents and digital media at home. it all depends on how you are using it. if you’re actually sitting down with your child, looking at it together, it’s a lot more effective and the child is getting a lot more out of it versus just sitting them in front of it and expecting to teach something to the child.” participant number of participants the number of participants facilitates technology integration 2: “i think this summer was the first time i ever did that [used technology], and it was because i had this huge group of kids.” perception of caregivers’ reactions provider’s perception of how the caregivers would react to technology use 1: “i think they would probably be open to it…. i don’t know if maybe the perception some parents don’t want any technology, that would keep some people from appreciating it. but i think in general, it would be wellreceived if we tried it.” responsive to children’s interests provider uses digital resources because the children show interest or engagement 10: “kids are automatically interested in that stuff. they don’t need to be enticed. you know, you just get out an iphone or an ipad and they’re, like, gasp.” library system access to equipment and resources provider has access to technology and tools 1: “... we have technology, i think, in our system to implement it. you know, e-readers and ipads and things that we can use in storytimes. and large screen tvs.” information technology and libraries june 2023 technology integration in storytime programs 9 cahill, ingram, and joo dimension factor operational definition representative quotes colleague support provider is part of a branch or system that shares information and resources for technology integration 17: “so, you know, we have, and we’ve gotten pretty [good] at sharing with other storytime providers in our system if we have any websites or anything that we’ve been using or music that works really well for ‘movers and shakers’ or anything like that.” expectation to integrate technology in programs provider feels pressure to integrate technology and is defensive about the choice not to do so 1: “i kind of apologize for it…. so, we have the technology available, and they encourage us to use it....” training provider has used or wants to use technology during storytime because of a training 17: “we did a digital mentoring training about how to appropriately model, like, tech skills and screen time with families. so we’ve been encouraged to add in a little bit more technology into our storytimes if we can do those, you know, in an appropriate way.” content interactivity provider can use technology to facilitate interactivity 24: “... i would love to use some, like, smart tvs, smart boards, those kind of things. just for some interactive songs and you know, activities... when i go into these kindergartens and first grade and second grade rooms, like, these kids are using the smart boards for interactive activities for abcs and colors and shapes and numbers. and it may be through an activity or a song that’s being used with that smart board. and i say, ‘oh, i love that! i wish i could do that!’” theme provider uses technology that clearly connects to the theme of the storytime 17: “actually in my kinderbridge storytime now, it’s shapes month. we have the osmotangrams that i bring out. so that’s one of the ones all four weeks i’m going to use the apps and bring out both of our ipads so that kids can practice those spatial shapes.” information technology and libraries june 2023 technology integration in storytime programs 10 cahill, ingram, and joo table 3. barriers to integrating technology in storytime dimension barrier operational definition representative quote storytime provider fear of difficulties/ problems provider doesn’t plan or hesitates to plan technology use because there may be problems with using it 13: “but technology can be a problem. when you’re planning or something and it’s not working.” previous/ own child’s experiences with tech provider has negative experience using technology with children 5: “i have a four-year old. and it’s interesting to see how he responds to technology and what he responds to. and what helps him to learn the most. and it’s just, like, night and day what he learns from. you know, hearing repeated songs and rhymes and just reading tons of books versus what he learns.… i mean, i think that probably the most he ever learned from an ipad was getting to watch sesame street. just sort of the same, sort of like watching a storytime, i think. but yeah, i think just now from experience seeing like, ‘oh! that really doesn’t. it’s not a helpful tool, i don’t think, for that age.’ just from my experience.” undecided about the value of tech provider is unsure if tech integration is appropriate 5: “i have been all over the board in terms of that subject … like i said, it’s really important for me to pack in as much of what i think they need in a storytime. and i don’t know, again, i’m not sure that i’m doing exactly what is correct and maybe i should be exposing them more. but i feel like, especially for threeto five-year olds, it’s one of those things.... screen time/ overuse concerns provider is concerned about children’s screen time 2: “because i think there’s plenty of opportunity to be had in other places.” information technology and libraries june 2023 technology integration in storytime

technology in storytime because they see storytime activities as equally or more beneficial 16: “and one thing that i’ve gotten feedback on is that kids are exposed to the technology in pretty much every facet of their life, so if we can make this a space where they can learn and experience things in a way that doesn’t have technology and they can see that it’s still really fun and exciting and we can learn a lot, then that has its own place, too.” unwilling to adopt a new technology provider keeps using the prior tool and does not try a new alternative technology 18: “i’m kind of old school

kids.” difficult to use tech with young children provider experiences difficulty using technology with young children 5: “i have found, for preschoolers, that it is really hard to incorporate anything

poor broadband network here, so not a lot of people have access to the internet. and so sometimes i feel like, also, showing them something that they can’t really utilize at home is not really helpful

provider believes technology is distracting 5: “personally, i think i kind of get distracted by the media, so, then i think they would, too. library system lack of access to devices library does not

smart tvs, smart boards, those kind of things.… we just don’t really have that option here.” lack of time to integrate tech into storytime, the provider has to have time to explore tools and know the best resources/media to integrate, and that takes time 1: “and part of it’s time, too. having the time to find quality resources, and to learn how to use them. because we have the technology, i think, in our system to implement it. “ information technology and libraries june 2023 technology integration in storytime programs 13 cahill, ingram, and joo dimension barrier operational definition

that’s a thing that we have struggled with previously because of our infrastructure and set-up. it was almost a hazard to set up a projector and have some sort of digital aspect to storytime.” information technology and libraries june 2023 technology integration in storytime programs 14 cahill, ingram, and joo discussion purposes experiential many of the storytime providers’ purposes for using technology revealed a goal to create a positive, engaging experience for all children and adults who attend storytime, a theme that prior research has highlighted.22 specifically, technology facilitates the sharing of visual aids, sound effects, and songs. providers also use technology to encourage adult participation, and like their early childhood educator colleagues, storytime providers in this study reported using technology to scaffold and coordinate children’s gross motor movements with songs and action rhymes.23 learning storytime providers’ responses also show the aim to contribute to the learning of children and adults in storytime. this finding mirrors those of goulding, shuker, and dickie, which found that providers like to use technology in ways that coincide with the aims of children’s services. 24 two of the purposes show an awareness of best practices in technology integration: support for adult-child interaction and teaching caregivers.25 additionally, storytime can be an opportune time for providers to model technology best practices for caregivers as providers have been modeling literacy best practices throughout the history of storytime programming.26 importantly, when storytime providers do model and intentionally seek to support caregivers’ learning, caregivers expand their knowledge, experience heightened confidence, and tend to utilize the strategies they encountered.27 notably, storytime providers tend to feel discomfort with providing instructional or developmental information directly to caregivers via “asides”; thus, a more palatable approach for many storytime providers might include using “we” language along the lines of “when we use digital media, we want to be sure that we are developing healthy habits. some families set a timer to help them monitor the duration of their children’s screentime.”28 one way that storytime providers might model digital media use is to search for and find information related to the storytime theme or book in one of the library’s databases. for example, if a book shared in storytime included a sloth, the storytime provider might demonstrate how to search for a video of a sloth in one of the library’s digital encyclopedias (e.g., encyclopedia britannica). storytime providers should also keep in mind that digital play can be incorporated into the informal activities that typically occur before and after storytime programs as a means to support children’s social interaction with other children.29 for example, if puzzles are typically included as one of the informal activity options before or after the storytime program, the provider might offer both traditional and digital puzzles (e.g., https://kids.nationalgeographic.com/games/puzzles/) on library-owned tablets and provide a simple how-to if needed. supports and barriers through the process of open coding, researchers identified four dimensions that storytime providers’ perceived supports and barriers could fall into based on the primary influential factor: provider, library system, participants, or content. provider the providers’ perceptions about technology and experiences with technology in the library setting serve as facilitators or barriers to integration. if a provider is aware of useful technology, familiar and comfortable with its use, knowledgeable of research supporting technology use, has a https://kids.nationalgeographic.com/games/puzzles/ information technology and libraries june 2023 technology integration in storytime programs 15 cahill, ingram, and joo professional philosophy that can accommodate technology use, and/or has had a positive experience trying out technology, then these may be factors that lead to the adoption of technology in storytime. on the other hand, if the provider has concerns about the difficulties of technology use or the amount of time children spend on screens, if the provider’s professional philosophy views storytime as a deliberate alternative to time with technology, or if the provider has had a negative experience with technology, then these may be factors that prevent the adoption of technology in storytime. these same factors affect early childhood practitioners and influence their decisions to incorporate technology into classroom practices.30 the factors that lead to technology integration could be seen as related to media mentorship. a media mentor has awareness, familiarity, knowledge, and a professional philosophy that supports technology use, all of which were factors identified by interviewees. professional training in mentorship was mentioned by one interviewee (17) who stated, “we did a digital mentoring training about how to appropriately model, like, tech skills and screen time with families.” thus , some providers’ responses indicate some general awareness of the currently emphasized best practice of media mentorship. however, the ambivalence toward the role of media mentor that goulding and colleagues found amongst librarians is also found here as interviewees’ responses do not give a clear picture of how they model technology use for caregivers during storytimes .31 in addition, responses that highlight barriers to technology integration show ways in which some providers are opposed to employing the role of media mentor specifically during storytime. as such, our findings align with prior observational studies that noted “few instances of librarians willing to speak directly to parents about how to interact with their children using technology.”32 participant providers consider the perspectives of the adult and child participants in storytimes in relation to integrating technology. providers are more likely to integrate technology if they view it as an aid to facilitating sessions for large groups, they believe caregivers will be open to the technology, and they appreciate that young children show a high interest in devices such as ipads. however, children’s high interest in devices was seen by other providers as a negative aspect of technology use and a barrier to integration because they thought children were too focused on the technology itself or would be distracted by the technology. just as early childhood teachers have been encouraged to broaden their perspectives of literacy to encompass digital literacy, so too might storytime providers, as this shift in focus would enable them to view these incidences as engagement rather than distraction.33 also, the same interviewee who thought caregivers might be open to technology in storytime expressed the concern that other caregivers might not like its use. our findings related to caregiver reaction echo similar findings from goulding and colleagues: the reaction that providers anticipate from adult participants might be either a support or a barrier for technology integration.34 library system two aspects of the library system were present in both factors and barriers: access and training. when the library system in which the provider worked gave them access to technology and training in its use for programs, they were more likely to integrate technology. in contrast, when a provider did not have access to technology, the library building did not support its use, or training was not given, the provider was less likely to integrate technology. libraries pride themselves on providing the highest level of service to members of the community and “removing barriers to access presented by socioeconomic circumstances.”35 yet, if libraries are to facilitate the digital learning of young children, it is necessary for them to recognize the digital divide impacting information technology and libraries june 2023 technology integration in storytime programs 16 cahill, ingram, and joo children’s access to technology throughout the world, and parents’ reluctance to spend money on digital apps.36 content content was a dimension only found in factors that support technology integration, not in barriers. providers used or wanted to use technology because they could connect the technology to two essential elements in the content of storytime: interactivity and theme. this dimension relates to purposes for technology use in the learning category as providers want to use the interactivity of technology as well as technology directly related to the session’s theme to boost children’s learning. indeed, child learning has long been librarians’ goal in providing storytime programs as has facilitating the development of parent skills.37 conclusion technology is prevalent in the lives of children and many begin interacting with digital tools as early as the first year of life; and caregivers seek guidance regarding their children’s technology use.38 while alsc has championed children’s librarians as media mentors, findings from this study, coupled with those from prior research, highlight storytime providers’ opposition to the media mentor role and the integration of technology within storytime programs.39 some first steps storytime providers might take are to integrate the digital tools the library is already providing. for example, if the library offers e-books (e.g., via libby), the storytime provider might consider integrating one or more picturebooks from that collection into storytime. alternatively, if the library does not have the tools necessary to share the book electronically during the program (e.g., a screen large enough for the storytime group), the provider might read the print version but then follow that up with a comment along the lines of “grownups, did you know that the library also offers this as an e-book that you could read on a phone, tablet, or other device? i would be happy to show you how to access it and other e-books after the program.” providers looking for other ways to incorporate digital tools into library programs might read strategies recommended by librarians in a fully and freely accessible online book.40 as scholars have previously noted, early childhood providers, including those who support young children and families in libraries, need much more professional development.41 specifically, the field needs more opportunities for librarians and other early childhood educators to develop their knowledge and skills within the realm of digital technology for young children, but they also need training that advances the notion of media mentor and boosts their confidence and identities relative to that role.42 the institute of museum and library services recently funded a project designed to support librarians’ knowledge and skills within the realm of family media for children ages five to eleven years—and products from that project are certainly a good starting place for storytime providers; however, additional resources and research focused on library programs and services designed for children from birth through five years are needed.43 if librarians are to embrace the media mentor role with confidence and the necessary knowledge and skills required of the task, much greater attention should be devoted to the responsibility and more support in the way of professional development and resources is necessary. acknowledgement this work was supported by the institute of museum and library services [federal award

university. david comeaux (davidcomeaux@lsu.edu) is systems and discovery librarian, louisiana state university. abstract the purpose of this study was to understand the viewpoints and attitudes of researchers at louisiana state university toward the new public search interface from sirsidynix, enterprise. fifteen university constituents participated in user studies to provide feedback while completing common research tasks. particularly of interest to the librarian observers were identifying and characterizing where problems were expressed by the participants as they utilized the new interface. this study was approached within the framework of the cognitive load theory and user experience (ux). problems that were discovered are discussed along with remedies, in addition to areas for further study. introduction the library catalog serves as a gateway for researchers at louisiana state university (lsu) to access the print and electronic resources available through the library. in 2018 lsu, in collaboration with our academic library consortium (louis: the louisiana library network), upgraded to a new library catalog interface. this system, called enterprise, was developed by sirsidynix, which also provides symphony, an integrated library system (ils) long used by the lsu libraries. “sirsidynix and innovative interfaces are the two largest companies competing in the ils arena that have not been absorbed by one of the top-level industry players.”1 there were several reasons for the change. most importantly, sirsidynix made the decision to discontinue updates to the previous online public access catalog (opac), known as e-library, and focus development on enterprise. in response to this announcement, the louis consortium chose to sunset the e-library opac in the summer of 2018. this was welcome news to many, especially the systems librarian, who had felt frustrated by the antiquated interface of the old opac as well as its limited potential for customization. the newer interface has a more modern design and includes features such as faceted browsing to better suit the twenty-first-century user. enterprise also delivers better keyword searching. this is largely because it uses the solr search platform, which operates on an inverted index. solr (pronounced “solar”) is based on open source indexing technology and is customizable, more flexible, and usually provides more satisfactory results to common searches than our previous catalog. inverted indexing can be conceptualized similarly to indexes within books. “instead of scanning the entire collection, the text is preprocessed and all unique terms are identified. this list of unique terms is referred to as the index. for each term, a list of documents that contain the term is also stored.”2 unlike the old catalog, which sorted results by date (newest to oldest), enterprise ranks results by relevance, like search engines. the new search is also faster because the results are matched to the inverted index instead of whole records.3 mailto:kblessi@lsu.edu mailto:davidcomeaux@lsu.edu information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 2 the authors wanted to investigate how well this new interface would meet users’ research needs. while library database and website usage patterns can be assessed through quantitative measures using web analytics, librarians are often unaware of the elements that cause frustration for the users unless they are reported. prior to enterprise going live, the library’s head of access services solicited internal “power users” in the library to use the new interface. power users were identified as library personnel in units who used the catalog daily for their work. this group included interlibrary loan, circulation, and some participants in research and instruction services. these staff members were asked to use enterprise as their default search to help discover problems before it went live. a shared document was created in google drive for employees to leave feedback regarding their experiences and suggestions for improvements. the systems librarian had access to this folder and periodically accessed it and made warranted changes that were within his control. several changes were made based on feedback from the internal user group. these included adding the term “checked out” in addition to the due date, and the adjustment of features that were not available or working correctly in the advanced search mode, such as date, series, call number, and isbn. several employees were curious about differences between the results in the old system and enterprise due to the new algorithm. additionally, most internal users fou nd the basic search too simplistic and not useful, so the advanced search mode was made the default search. among the suggestions, there was also praise for the new interface. these statements were regarding elements of the user-enablement tools, such as “i was able to login using my patron information. i really like the way that part functions,” and from areas where additional information was now available, such as “i do enjoy that it shows the table of contents —certainly helps with checking citations for ill.” while the feedback from internal stakeholders was helpful, the authors were determined to gather feedback from patrons as well. to obtain this feedback, the authors elected to conduct usability studies. usability testing employs representative users to complete typical tasks while observers watch, facilitate, and take notes. the goal of this type of study is to collect both qualitative and quantitative data to explore problem areas and to gauge user satisfaction.4 enterprise includes an integration with ebsco discovery service (eds) to display results from the electronic databases subscribed to by the library as well as the library’s holdings. eds was implemented several years ago as a separate tool. the implementation team suspected that launching enterprise with periodical article search functionality might be confusing to those who were not accustomed to the catalog operating in this manner. therefore, for the initial roll-out, the discovery functionality was disabled in enterprise, leaving it to function strictly as a catalog to library resources. this decision will be revisited later. like many other academic libraries, eds is currently the default search for users from the lsu libraries homepage. other search interfaces, labeled “catalog,” “databases,” and “e-journals,” are also included as options in a tabbed search box. conceptual framework two schools of thought helped to frame this research inquiry: cognitive load theory and user experience (ux). cognitive load theory relates to the amount of new information a novice learner can take on at a given time due to limitations of the working memory. this theory originated in the field of instructional design in the late 1980s.5 the theory states that what separates novice learners from experts is that the latter know the background, or are familiar with the schema of a information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 3 problem, whereas novices start without this information. accordingly, experts are able to categorize and work with problems as they are presented, whereas new learners need to formulate their problem-solving strategies while encountering new knowledge. as a result, novices are quicker to max out the cognitive load in their working memories while trying to solve problems. ux emerged from the field of computer science and measures the satisfaction of users with their experience with a product. a 2010 article reviewed materials published in 65 separate studies with “cognitive load” in the title or abstract.6 early articles on cognitive load focused on learning and instructional development. these studies concentrated on limiting extraneous information (e.g. , materials and learning concepts), which affects the amount of information able to be held in the working memory.7 while the research that developed cognitive load theory centered on real-life problemsolving scenarios, later research focused on its impact in e-learning environments and learning regarding this delivery mode.8 in contrast to cognitive load theory, which was formed by academic study, the concept of ux was developed in response to user/customer satisfaction, particularly regarding electronic resources such as websites.9 user testing allows end users to provide realtime feedback to developers so they see the product working, and in particular, to note where it could be improved. ux correlates well with cognitive load theory for this study, as the concept arose with the widespread use of computers in the workplace and in homes in the mid-1990s. user studies user expectations have shifted beyond the legacy or “classic” opac, originally designed for use by experienced researchers with the primary goal of searching for known items.10 user feedback has historically been sought when libraries release new platforms and services and to gauge user satisfaction regarding research tools. “libraries seek fully web-based products without compromising the rich functionality and efficiencies embodied in legacy platforms.”11 a study by borbely used a combination of the log files of opac searches and a satisfaction questionnaire to determine which factors were most important to both professional and nonprofessional users. their findings indicated that task effectiveness, defined as the system returning relevant results, was the primary factor related to user satisfaction.12 many of the articles dealing with user studies and library holdings published in recent years have focused on next-generation catalogs (ngcs). this was defined in a 2011 study by 12 characteristics: “a single point of entry for all library resources, state of the art web interface, enriched content, faceted navigation, simple keyword search box with a link to advanced search box on every page, relevancy based on circulation statistics and number of copies, ‘did you mean . . .’ spell checking recommendations/related materials based on transaction logs, user contributions (tagging and ranking), rss feeds, integration with social networking sites, and persistent links.”13 catalogs defined as next-generation provide more options and functionality in a user-friendly, intuitive format. they are typically designed to more closely mimic web search engines, with which novice users are already familiar. tools within ngcs such as the faceted browsing of results have been reported as popular in user studies, especially among searchers without high levels of previous search experience. “faceted browsing offers the user relevant subcategories by which they can see an overview of results, then narrow their list.”14 a 2015 study interviewed 18 academic librarians and users to seek their feedback regarding new features made possible by ngcs. their findings indicate “that while the next-generation catalogue interfaces and information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 4 features are useful, they are not as ‘intuitive’ as some of the literature suggests, regardless of the users’ searching skills.”15 this study also indicated that users typically use the library catalog in combination with other tools such as google scholar or worldcat local both for ease of use and for a more complete review of the literature. while enterprise contains the twelve elements that yang and hofmann defined for a ngc, since the discovery element has been disabled, lsu libraries use of enterprise may be better described as an ils opac with faceted results navigation. while the implementation of discovery services and other web tools has shifted users to sources other than the catalog, many searchers often still prefer to use the library’s catalog. reasons for this may include familiarity with the interface, the ability to limit results to smaller numbers, or the unavailability of specific desired search options through other interfaces. problem statement the purpose of this study was to understand the viewpoints and attitudes of university stakeholders regarding a new interface to the online catalog. in particular, four areas were investigated: 1. identification of problems searching for books on general and distinct topics. 2. identification of problems searching for books with known titles and specific journal titles. 3. exploration of the usability of patron-empowerment features. 4. identification of other issues and/or frustrations (e.g., “pain points”). methodology three groups of users were identified for this study: undergraduate students, graduate students, and staff/faculty. the student participants were the easiest to recruit due to a fine forgiveness program that was initiated at lsu libraries in 2016. this program gives library users the option of completing user testing in lieu of some or all of their library fines (up to $10 per user test). all the student participants were recruited in this manner. additionally, five faculty/staff members identified as frequent library users were asked to participate. the participant pool for user testing included five undergraduate students, five graduate students, and five faculty and staff members. each of these groups had five participants, which is considered a best practice in user testing.16 the total sample studied for this study was 15 library users representing these three unique user groups. these participants are described in more detail in appendix a. for the observations, individuals were brought to the testing room in the library. this is a small neutral conference room with a table, laptop, and chairs for the librarian observers and participants. each participant was tested individually and was asked to speak aloud through their thought process as they used the new interface. the authors employed a technique known as “rapid iterative testing.” this type of testing involves updating the interface soon after problems are identified by a user or observer. thus, after each user test, confusing and extraneous information was removed applying cognitive load theory, improving the interface in alignment with the concept of ux. this approach helped to minimize the number of times participants repeatedly encountered the same issues. this framework makes this study more of a working study than a typical user study. a demonstration of this type of testing is included as figure 1. information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 5 before after figure 1. iterative testing model. this shows the logon screen before and after it was modified. this was based on the observation that users were unsure what information to enter here. the software usability studio was utilized to record audio and video of the participants’ electronic movements throughout each test. although the software can also record video of users throughout tests, the authors felt that this may make the participants uncomfortable and possibly more reluctant to openly share their opinions. at the beginning of each user study, participants were informed of the purpose of the study, the process, and the estimated time of the observation (30 to 45 minutes). the participants were then asked to sign a consent form for participation in the study. the interviews began with two open-ended pre-observation questions to gauge the users’ previous library experience. the first question asked students whether they had received library training in any of their courses, or, if the participant was a teaching staff or faculty member, if they regularly arranged library instruction for their students. the second question explored if they needed to use library resources in a previous assignment or required these in one they had assigned. then volunteers were given a written list of four multi-part task-based exercises, detailed in appendix b. these exercises were designed to evaluate the areas of concern outlined in the problem statement and to let the users explore the system, helping the observers discover unforeseen issues. the observations ended with two follow-up questions that asked the participants to describe their experience with the new interface. they were asked what they liked and what they found frustrating. they were also asked if there were areas where they felt they needed more help, and how the design could be made more user friendly. after the testing was completed, the audio files were imported into temi, a transcription tool that provided the text of what the users and the observers said throughout the test periods. the authors reviewed these transcripts and the recorded videos of the user’s keystrokes within the system for further clarity. the process and all instruments involved were reviewed by the lsu institutional review board prior to the testing. all user tests took place from march through november 2018. information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 6 findings previous library training and assignments three of the five undergraduate participants had received some previous library training fro m their professors or from a librarian who visited their classes. those that had training tended to recall specific databases they found useful, such as cq researcher or jstor. the assignments requiring library research mentioned by the undergraduate participants typically required several scholarly resources as a component of an assignment. four out of five of the graduate-student participants also indicated that they had some library training, and most also indicated they used the library frequently. two of the graduate-student participants, both studying music, mentioned that a research course was a required component of their degree program. the staff and faculty members tested mentioned that, depending on the format of the course, they either demonstrated resources to their students themselves, or would request a librarian to teach more extensive training. participant 13, a teaching staff member, mentioned that in a previous class she was “able to get our subject librarian to provide things to cater to the students, and they had research groups, so she [the subject librarian] was very helpful.” some of the teaching staff and faculty mentioned providing specific scholarly resources for their students. they acknowledged that since these were provided, their students did not gain hands-on experience finding scholarly materials themselves. participant 10, a faculty member, stated that she usually requires that students in one of her courses “do an annotated bibliography. i’ll require that they find six to ten sources in the library and usually require that at least three or four of those sources be on the shelf physically, because i want them to actually work with the books, and in addition, to avail themselves of electronic resources.” most of the staff and faculty participants indicated that, despite its weaknesses, they preferred using the online catalog over eds, mainly because eds included materials outside of our collection. when asked to explain, participant 12, a staff member said, because i feel like [with] ebsco you get a ton of results, and you know, i’m still looking for stuff that you guys have. um, [however] because of the way the original catalog is, i feel like i have to go through discovery to get a pretty accurate search on what lsu has. because, when i do use the discovery search, it’s a lot more sensitive, or should i say maybe a lot less sensitive, and it will pick up a lot of results. . . . it searches your catalog really well, just like worldcat does. . . . so, if the catalog was the thing that was able to do that, that would be cool. if the catalog search was more intuitive and inviting, i wouldn’t even bother going to some of these other places. books: general and distinct topics the observers noticed multiple participants using or commenting on known techniques learned from experience with the old catalog interface. these included boolean operators such as and to connect terms within the results. enterprise does not include boolean logic in its searches. a goal of the structure for the new algorithm is to provide a search closer to natural language. while most of the student participants typically searched by keyword when searching for books on general topics, staff and faculty participants typically preferred to search within the subject or title fields. faculty and staff participants also actively utilized the library of congress subject heading links within records and said that they also recommended that their students find materials in this manner. participant 9, a faculty member, said that he usually told his students to “find one book, then go to the catalog record . . . where you’ll get the subject headings. because . . . you’re not going information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 7 to guess the subject headings just off the top of your head, and that's how they are organized. that's the best way of getting . . . your real list.” many users were able to deduce that a book was available in print based on the call number listed. however, some undergraduate-student participants were confused by links in individual records and assumed that these were links to electronic versions of the book. these primarily linked to additional information about the book, such as the table of contents. the observers also found that many students used the publication date limiter when searching for materials, while commenting that they typically favored recent publications, unless the subject matter made a historical perspective beneficial. the date limiter, while effective for books, is less effective for periodicals, which include a range of publication dates. more advanced researchers, such as one staff participant, enjoyed the option to sort their results by date, but sorted these by “oldest first” indicating that they did this to find primary documents. known title books none of the user groups tested had trouble locating a known book title within the new interface, although two undergraduate students remarked that they preferred to search by the author, if known, to narrow the results. most undergraduates determined if the books were relevant to their needs based on the title and did not explore the tables of contents or further information available. graduate students tended to be more sophisticated in their searches for relevance and used the additional resources available in the records. participant 12, a staff member, mentioned that he liked the new display of the results when he was searching for a specific book. while the old system contained brief title information in the results display, he believed the new version showed more pertinent information, such as the call number, in the initial results. he said, “and this is also great too, because the old system . . . you would bring up information, then there’s another tab you have to click on to get to the . . . real meat of it. so . . . this is really good to see if it’s a book, to know what the number is immediately, just to not have to go through so many clicks.” specific journals specific journal results were problematic and were confusing in multiple ways. the task regarding journals directed users to find a specific journal title within enterprise, and then to determine whether 2018 issues were available and in what format (e.g., print or electronic). all the student users had trouble determining whether a journal was in print or electronic and if the year they needed was available. the task of finding a specific journal title and its available date range was also troublesome to many students. the catalog lists “publication dates” for journals prominently in the search results. however, these dates indicate the years that a journal was published, not the years that the library holds. users need to go into the full record for a journal to see the available years listed under the holding information. unfortunately, this was not intuitive to many. additionally, the presentation of years in records for journals was also unclear to some. for instance, participant 2, a freshman, did not understand that a dash next to an initial date (e.g., 2000–) indicated that the library held issues from 2000 to the present. many student users, especially those familiar with google scholar or eds, did not understand that journals are solely indexed in the catalog by the title of the journal. this is problematic for those who are accustomed to more access points for journals, such as article title and author. journals were additionally confusing because each format (e.g., print, electronic, or microfilm) has its own record in the catalog. typically, users clicked on the first record with the title that matched information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 8 the one they required, and assumed that this was all that was available, rather than scrolling through the results to view the different formats and the varying years within. this issue was problematic for all the student participants. participant 5, a phd student, summed up this frustration by saying, “i find stuff like that sometimes when i’m looking for other things. like, it shows the information [for the journal] but great, awesome. i found that [the journal] is maybe, hopefully somewhere, but sometimes you click on whatever link they have, and it goes to this one thing and there’s like one of the volumes available. so, this is not useful.” while records in the past used to be cataloged with all the holding information in one record, a better functionality for end users, this practice was changed in the midto late 2000sdue to the updating of journal holdings was a manual process completed by technical services staff. this timeframe was when the influx of electronic journal records began to steadily increase, making this workflow too cumbersome. due to all these known issues with journals, when asked to search for a specific journal in the catalog, several advanced searchers (graduate students, staff, and faculty) indicated they would not use the catalog to find journals. several stated other sources they preferred to use, whether google scholar, interlibrary loan, or subject-specific databases in their fields. after fumbling around with the catalog, participant 12, a staff member, summed this up by saying, “i guess if i was looking for a journal, i would just go back to the main page, and go from there [from the e-journals option]. i haven’t really searched for journals from the catalog. the catalog is usually my last [resort], especially for something like a journal.” usability of patron-empowerment features many participants were confused by the login required to engage with the patron-enablement tools prior to the iterative changes demonstrated in figure 1. once changes were made clarifying the required login information, patrons were able to use the patron-enablement tools well, placing holds and selecting the option to send texts regarding overdue materials. however, few undergraduate participants intuitively understood the functionality of the checkboxes next to records to retrieve items later. some participants assumed that they needed to be logged into the system to use this functionality, similar to eds. participant 1, a senior, said that she used a different method for retrieving items later, stating “normally, i'm going to be honest, if i needed the actual title, i’d put it in a word document on my computer. i wouldn’t do it on the library website.” another graduate student, participant 14, stated that while he was aware of the purpose of the checkboxes, he would not use them because the catalog would not be the only resource he would be using. he said that his preference was to “keep a reference list [in word] for every project. and then this reference list will ultimately become the reference for the work done.” participants in every category noted that they did not usually create lists in the catalog to refer to them later. there was enthusiasm regarding the new option to text records, with participant 6, a staff member, going so far as to say “boy, this is gonna make me very annoying to my friends” and staff participant 12 stating “that’s a really cool feature. i think that’s more helpful than this email to yourself.” unfortunately, there were several issues discovered regarding the text functionality. the first issue was that it was not reliably working with all carriers. once that was resolved, the systems librarian removed extraneous information regarding the functionality. this included text that “standard rates apply” and a requirement for users to choose their phone carrier before a text could be sent. these were both deemed unnecessary as it was assumed that users would information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 9 know whether they were charged for receiving text messages. additionally, one of the international graduate student participants did not understand the connection between texting information and the tool to do this, which was titled “sms notification.” while the texts were successful while the users were performing the studies, it was discovered later that the texts did not include the call numbers for items. after discussion regarding this problem arose at a louis conference, the decision was made to hide texting as an option until the system was able to properly text all the necessary information. when sirsidynix can fix this issue, the language around this will likely be made more intuitive by labeling it “text notifications” instead of sms. other issues and frustrations the researchers noticed that some options were causing confusion, such as the format limiter. under this drop-down option, several areas were displayed that did not align to known formats in the lsu collections, such as “continuing resources.” to remedy this, all the formats that could not be identified were removed as options. another confusing element was the way that records were displaying in initial user tests. some marc cataloging information was visible to users, so the systems librarian modified the full record display to hide this information. originally, the option to see this information was moved to the side under an option to “view marc record.” however, since this still seemed to confuse users, this button was changed to “librarian view.” undergraduate-student users reported confusion when they needed to navigate out of the catalog into a new, unfamiliar database interface to obtain an electronic article. participant 3, a senior, described her feelings when this happened, that she felt like she was “not in the hands of lsu anymore. i’m with these people, and i don’t know how to work this for sure.” another undergraduate user gave the suggestion that the system provide a warning when this occurs, so users knew that they would be navigating in a new system. since so many of the records link to databases and other non-catalog resources, this was not pursued. several undergraduate-student users mentioned that they didn’t understand the physical layout of the library, and that they used workarounds to get the materials they needed rather than navigate the library. for example, some were using the “hold” option in the catalog to have staff pull materials for them for reasons not initially intended by the library. rather than using this feature for convenience, they stated they were using it due to a lack of awareness of the layout of the library or the call number system. one user, participant 4, a sophomore, used the hold feature to determine whether a book was in print or electronic. when she clicked on the “hold” button in a record and it was successful, she said “okay, so i can place a hold on it, so i’m assuming there is copy here.” follow-up questions feedback to the new interface was primarily positive. several participants mentioned that the search limiters were now more clearly presented as choices from drop-down boxes. additionally, result lists are now categorized by facets such as format and location, which users had options to “include” or “exclude” at their discretion. participant 9, a faculty member, particularly liked the new library of congress subject facet from within the search results. she mentioned that these were available in the past interface, but the process to get to them was much more cumbersome. she regarded this new capability as a “game changer” and “something she hadn’t even dreamed of.” experienced searchers, such as participant 6, a staff member, noticed and appreciated the improvements in search results made possible by the new algorithm. she said, “it’s very easy to information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 10 look at, especially compared to the old database, and the keyword searching is a lot better.” after conducting a brief search, another staff member, participant 12, mentioned that he thought the results returned by an author search were much more relevant than in the past. he said, “sometimes with the older system even name searches can be sort of awful. i mean . . . this is a lot better. . . . if you type in benjamin franklin, for me at least, it’s difficult to get to the things he actually wrote. you know, you can find a lot of books about [them], and so you kind of have to filter until you can find . . . the subject.” figure 2. catalog disclaimer. the new search is also more forgiving of misspellings than the old version, which responded with “this search returned no results” when an item was misspelled. those who were very familiar with the old interface, such as staff and faculty, were particularly excited by small changes. these included being able to use a browser’s back button instead of the navigation internal to the system, or the addition of the isbn field to the primary search. prior to the new interface, the system would give an error message when a user attempted to use a browser’s back button instead of the internal navigation. additionally, users mentioned that they liked that features were similar to the previous interface with additional options. an example of a new feature is the system employing fuzzy logic to provide “did you mean” and autocomplete suggestions when users start typing in titles they are interested in, similar to what google provides. this same logic also returns results with related terms, eliminating the need for truncation tools.17 one graduate student, however, particularly mentioned missing boolean operators; they thought they were helpful because students had been taught these and were familiar with them. due to this comment, and other differences between the old and new interfaces, a disclaimer was added to information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 11 make users aware of these changes (see figure 2). two of the five undergraduate participants and two faculty participants noted if they didn’t understand something, or needed help, they would ask a person at a service desk for assistance. one of the staff members mentioned she would use the virtual chat if she had a question regarding the catalog. she also suggested that a question mark symbol providing additional information when clicked might be helpful if users got confused in the system. to allow users to provide continued feedback, the systems librarian created a web form for users to ask questions or report errors regarding the system. discussion study participants requested several updates; unfortunately, some of the recommendations suggested were in areas where the systems librarian had little control to make changes. since the initial advanced search was not easy to customize, the systems librarian created a custom new advanced search that more closely fit the needs of catalog users than the built-in search. one limitation of the default advanced search that several participants and staff users noted was the inability to limit by publication date. to work around this problem, one of the features the systems librarian implemented in the custom search was a date-range limiter. while still falling short of the patrons’ desired outcome of inputting a precise date to limit by, the date range feature was still a step forward. he was also able to make stylistic changes, such as bolding fields or making buttons appear in bright colors to make them more visible. other changes included eliminating confusing options and reordering the way full records appeared. this included moving the call number to a more visible area than where it was originally located. after a staff participant suggested it, he was also able to make the author name a hyperlinked field. now users can click on an author’s name to see what other books are available by that author within the library. the systems librarian was also able to make the functionality of the checkboxes more intuitive by adding a “select an action” option at the top of the list of results, which more clearly indicated what could be done with the checked options. these include being added to a list, printed, emailed, or placed on hold. the username and pin required to engage with the user-enablement tools was continually problematic, and not intuitive. only one of the student participants knew their login information, a graduate student close to graduation. the user name is a unique nine-digit lsu id number, which students, faculty, and staff don’t often use. the pin is system generated, so there is no way users could intuit what their pin is. once the user selects the “i forgot my pin” option however, the pin is sent to them, and then they have the option to change it to something they prefer. this setup is not ideal, especially since many other resources on campus are accessed through a more familiar text-based login and password. the addition of “i forgot my pin” to this part of the interface helps by anticipating and assisting with this problem by providing an example with the nine-digit id number, but this can also be overlooked. for this reason and for other security reasons related to paying fines, the library is exploring options to provide a single-sign-in login mechanism. the lack of knowledge regarding the physical layout of the library cannot be solely blamed on the users. in 2014, the lsu libraries made several changes to middleton library, the main campus library. the first was the closing of a once distinct collection, education resources, whose titles were merged with the regular collections. the second was weeding a large number of materials on the library’s third floor to facilitate the creation of a math lab. the resulting shifting of the collection had a direct impact on how patrons were able to locate materials within the library. due to required deadlines, access services staff needed to place books in groupings out of their typical information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 12 call number locations. the department is still working to remedy this five years later. in addition, service points previously manned to assist with wayfinding on the third and fourth floors were closed. conclusion to optimize whatever resources the library provides, user feedback is a useful tool. however, there are limitations to this study, the most obvious being that the data collection took place and was based on researchers at one institution. this could limit the applicability of the study’s results. the second is regarding the sampling method for user tests. student users self -selected by volunteering in lieu of user fines, and staff and faculty identified as frequent library users, were purposively selected. less-experienced users may have encountered different issues as they navigated the system. most of the student participants indicated they had received library training in some manner, and that they had been required to use library resources in the past to complete assignments. only a small number of participants were undergraduates without library training. the authors noted that the student participants who had received library training were more likely to attempt complicated searches and to explore advanced features. however, they also tended to try to conduct searches that were optimized for the previous catalog, such as using boolean logic. those with library training were also more likely to identify problematic areas, such as searching for journals, and to develop workarounds to get the materials they desired. the two graduate students in music, who were required to take a research course, both indicated how helpful this knowledge was to conducting research in their field. the user tests in this study demonstrated which information points the users at lsu found to be the most relevant, which allowed the system librarian to redesign a search that better fit their needs. this included hiding or separating extraneous information, such as additional information regarding texting, and making changes so all marc coding only appeared under the newly created “librarian view.” while this study demonstrated that the advanced researcher participants created workarounds regarding journal searches, undergraduate participants also created workarounds (such as placing holds) to accommodate their lack of knowledge regarding the library system and the physical library. several of the undergraduate participants reported having anxiety regarding their ability to navigate systems when the catalog linked to databases with interfaces new to them. the authors found that more advanced researchers appreciated having more data in catalog records, such as information on publishers and library of congress subject headings. students without as much exposure to library resources tended to prefer to conduct keyword searches and were more likely to judge the relevance of a record based mainly on the title or year of publication. most of the staff and faculty participants in this study indicated that they preferred to use the opac over eds. less-seasoned researchers tended to prefer ease and convenience over additional control and functionality. these kinds of generalizations could be tested by additional studies at other universities. the new user-empowerment features were received positively, especially the new “text notifications” feature. most participants indicated that they found it easy to renew items within the interface. however, the authors discovered that few patrons indicated they would u se “my lists” to capture records they would like to retrieve later. the user tests highlighted how many problems lsu library users are having signing on to the system to utilize the user-enablement tools. it is hoped that the upcoming change to a single sign on will alleviate these issues and the users’ frustrations. the systems librarian would like to incorporate other changes, such as the information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 13 request to return to the same spot on a list after going into a full record rather than returning to the top of the list. he is also planning on programming the mobile view for the catalog soon. currently the mobile site is still linking to the desktop version. he has also reintroduced the option to conduct a boolean search by linking to the old catalog due to so many users being familiar with it. the text messaging is expected to be corrected in an upcoming upgrade. overall, response from the participants in this study was positive, especially regarding the new algorithm. they also appreciated the familiarity of the design with the previous catalog interface, with additional features and functionality. regardless of the limitations in this study, some of this study’s findings reaffirm those from previous user studies. these include researchers indicating a need to consult multiple resources either in combination with or in exclusion of the catalog, and ngcs not being as intuitive as expected. the need to consult multiple resources particularly correlated with this study’s findings regarding journals. librarians were aware that searching journals in the online catalog was tricky for users due to multiple issues. many of the experienced participants in this study mentioned that they appreciated the new algorithm because it provided more accurate results. this reaffirmed results from the borbely study, which indicated that task effectiveness, or the system returning relevant results, as the primary factor related to user satisfaction. also similar to findings from the literature, users appreciated the newly available faceted-browsing features. dissimilar to a previous study however, it was the advanced searchers, rather than the novices, who mentioned these specifically as an improvement.18 the authors noted that it was common for undergraduate library participants to express confusion regarding navigating the physical library, so the library has taken several steps to remedy this. since this user testing was completed, a successful grant was written to provide new digital signage to replace outdated signage. this digital signage will be much more flexible and easier to update than the older fixed signage. additionally, this grant provided a three-year license to the stackmaps software. this software has since been integrated into the catalog and eds tool to direct users to physical locations within the libraries. additionally, the access services department updated physical bookmarks that display the call number ranges and resources available on each floor. these are now available at all the library’s public service desks. the library will also continue providing the popular “hold” services for patrons. this is a relatively new service, which was started to offset confusion and to assist patrons during the construction they may have encountered during the changes to the library. finally, since the fine forgiveness program has been so fruitful regarding recruitment for user studies, the special collections library also anticipates providing user studies in lieu of photocopying costs in the future. future research these user tests made it obvious that finding specific journal information through the catalog was difficult for most users. this is an area that needs remediation, and the systems librarian plans to conduct further user testing to explore avenues to make searching for journal holdings more efficient. another potential area for further study includes assessing enterprise’s integration of article records. as previously mentioned, enterprise can be configured to include article-level records into its display. however, this functionality would duplicate an existing feature of our main search tab, an implementation of eds that we have labeled “discovery.” while the implementation team felt that duplicating this functionality on a search tab labelled “catalog” might initially confuse users, replacing our current default search tab with enterprise warrants information technology and libraries march 2020 user experience with a new public interface | blessinger and comeaux 14 serious consideration. an additional area to explore is a rethinking of the tabbed search box design. while the tabbed design remains popular in libraries, a trend toward a single search box on the library homepage has been observed in academic libraries.19 a future study with an emphasis on determining the best presentation of a various search interfaces, including either a reshuffling of available tabs or a move to a single search box, is planned in the foreseeable future. information technology and libraries march 2020 user

(side note: yes, i know what you’re thinking and yes, we did, we opened two of the new branches during the pandemic—definitely fodder for another article.) the branch amhs have interior and exterior return windows and sit along a glass wall so patrons can watch their items ride the conveyor belts and drop into sorting bins. the staff side has an inductor for items being returned from or sent to other branches, so there is almost always something for the public to watch (see figure 1). men, women, children, young and old enjoy watching the amh and asking questions. some patrons bring their out of town guests (even a nun visiting from ireland) to see the amh in action. this spontaneous interaction bolsters our connection with visitors and subconsciously reinforces the concept of “library as safe exploration.” a frequent question is “how does this work?” our explanation of tags and coding is the perfect opportunity to suggest books, point out games, and promote upcoming classes. we follow a roving customer service model. because an amh is an efficient tool that checks in items and deposits them in pre-determined bins for easy shelving, we have freed up hours of staff time that can now be spent in the stacks, helping patrons find items and answering questions as needed. delivering an excellent amh experience for staff has been more complicated. as befitting a port county, we went full steam ahead with new technology, new locations, and increased services. this required all staff to simultaneously learn new systems and change many of our in-house procedures while continuing with daily operations. every detail, from how to sort for shelving to labeling shipments, needed to be re-examined. the biggest changes came with bringing the central sorter online. some of the changes were technical. for example, we use rfid tags as an identification number and place a matching barcode on each item. rfid is excellent technology; tagging all our items has completely changed and streamlined our process. most items come pre-processed and the amhs are set to only read the rfid. an unintended, but useful consequence is that we have become more aware of vendor processing errors where tags and barcodes don’t match. (side note: we are working on some system-wide solutions to locate discrepancies between barcode numbers and rfid tags in the ils; rfid is another topic entirely, so stay tuned.) mailto:williamscar@ccpl.org information technology and libraries september 2021 delivering| williams 2 figure 1. children returning books to the automated materials handler at a branch of the charleston public library. another benefit of the amh is that our library collections acquisitions and technical services (lcats) department realized that as they processed new orders, they could now send those items out daily instead of waiting to accumulate enough individual branch materials for a separate shipment—a win for patrons (new materials every day) and lcats (storage space.) the unexpected twist: our adult, ya, and children’s’ librarians are accustomed to receiving new materials separately from returns so they can familiarize themselves with the titles before the items are shelved. with the central sorter, new items go out daily mixed in with the rest of the daily shipment. spine tape makes it is easy for circulation staff to separate the new adult items, but we still needed a solution for children and ya. after several sort changes and many discussions, we went old school, recycling used paper into book flags. the flagging doesn’t cause a problem with the amh, is quick for technical services to place in each new book and is easy for circulation to spot and put aside at the receiving location. some of the changes were electrical. only the four new branch locations and support services facility have an amh, while the other fourteen branches check in items by hand. we added a tote check-in server (tcs) system to the central sorter. this feature creates a manifest of the items in each crate. branches can now receive the contents of each crate by entering a 4 -digit barcode instead of scanning individual items. an unintended consequence to our new internet-dependent system that we had not anticipated was electricity. the coast has frequent thunderstorms that can information technology and libraries september 2021 delivering| williams 3 cause power outages and flooding. if the power is out, there is no way to sort or receive the items in delivery. luckily this doesn’t happen often, and so far, power has been restored quickly. some of the changes were physical. our delivery drivers also process the shipment when they return each day. in their previous workflow, most of the shipment was delivered to the downstream libraries. the parts of the shipment that they did process had printed routing slips placed in each item, so staff could all be sorting the shipment at the same time. now their department has become logistics, which is a more encompassing title and better covers the wider variety of tasks the staff have added to their day. in addition to delivery and mail duties, logistics also manages and maintains the amh and tcs equipment, troubleshooting problems that arise, scanning barcodes, and processing an average of 3000 items daily with the amh. most of the shipment is now coming through the central sorter—staff handle an average of 157 crates each weekday, moving items from support services and to/from branches. we have electric forklifts that hold three crates at a time to help with the increase in physically shifting the crates. now one person inducts the shipment while others scan and stack the crates on the loading dock. this procedure is much faster than the previous paper slip method and processing is usually finished in a couple of hours. other changes were mental and emotional. new locations, renovations, technologies, and procedures can be exciting, but can also lead to change fatigue. fortunately, everyone retained their job this past year, but in order to operate a new branch built in a previously unserved community, we had to reassign staff from locations closed for renovation. ccpl’s vision is for our library to be the path to our cultural heritage, a door to resources of the present, and a bridge to opportunities in the future. we are doers, creators, servers, and teammates, not only to the community, but to our coworkers. we are all in for our shared vision, but whew. . . some days we all experience mental eye rolling and collective sighs of “another change?” our director’s mantra is “we are the calm.” and it is true. by fall we will have three of the renovated branches reopened, three more under renovation and another staffing shift. with some grace and encouragement to one another, we will handle whatever comes next. from chatgpt to catgpt: the implications of artificial intelligence on library cataloging article from chatgpt to catgpt the implications of artificial intelligence on library cataloging richard brzustowicz information technology and libraries | september 2023 https://doi.org/10.5860/ital.v42i3.16295 richard brzustowicz (rrbrzustowicz@carlow.edu) is instruction and outreach librarian, carlow university. © 2023. abstract this paper explores the potential of language models such as chatgpt to transform library cataloging. through experiments with chatgpt, the author demonstrates its ability to generate accurate marc records using rda and other standards such as the dublin core metadata element set. these results demonstrate the potential of chatgpt as a tool for streamlining the record creation process and improving efficiency in library settings. the use of ai-generated records, however, also raises important questions related to intellectual property rights and bias. the paper reviews recent studies on ai in libraries and concludes that further research and development of this innovative technology is necessary to ensure its responsible implementation in the field of library cataloging. introduction as librarianship continues to evolve in the digital age, the importance of cataloging as a tool for accessing vast amounts of information cannot be overstated. unfortunately, this crucial process can be both labor-intensive and time-consuming, often requiring significant resources. in recent years, automation and artificial intelligence (ai) technologies have emerged as potential solutions for streamlining workflows. openai’s language model chatgpt1 is one such technology, offering the potential to automate various tasks, including text generation and even creating working code.2 this paper explores the potential applications of chatgpt in library cataloging, examining the results of my own experiments using this innovative technology. literature review large language models (llms) applications have been explored in a range of contexts. taecharungroj explores reactions to chatgpt, noting wide public interest expressed via social media posts. due to chatgpt’s ability to generate accurate information in a conversational tone, it provides an accessible medium for interacting with an ai resource. these technologies will usher in substantial changes to how we do our work: “the next evolution of jobs will likely be impacted by chatgpt and other innovative ai technologies.”3 at the same time, the author cautions that while chatgpt performs admirably in generating semantically and syntactically correct information, it does not always provide accurate information. therefore, this presents an opening for targeted professional development opportunities in fields that may be affected by llms. kasneci et al. argue that ai and language models, if used effectively, are an opportunity for better, more learner-centered education. they caution, however, that llms’ potential for bias may necessitate careful training and review of records by professionals: “[i]f a model is trained on data that is biased towards certain groups of people, it may produce results that are unfair or discriminatory towards those groups (e.g., local knowledge about minorities such as small ethnic groups or cultures can fade into the background).”4 to counter the potential for bias and abuse, the authors advise that individuals using these resources should ensure that the data training the mailto:rrbrzustowicz@carlow.edu information technology and libraries september 2023 from chatgpt to catgpt 2 brzustowicz ai systems are diverse and inclusive. to that end, they recommend making the data open and available to users. likewise, the authors recommend regular reviews and continuous updates of ai models. this will ensure not only that the ai (e.g., chatgpt) generates accurate information, but it will also provide a model for continuous improvement of the machine learning algorithm.5 recent research has examined the potential of chatgpt in the library context. lund and wang discuss the implications of chatgpt for libraries and the academy. according to their findings, chatgpt can enhance library search systems’ accuracy and effectiveness by automatically generating cataloging and metadata for library resources, such as book titles and descriptions.6 however, they also note the potential ethical and legal implications of using chatgpt. as chatgpt draws on publicly available material, it may include copyrighted content, necessitating careful evaluation of ai-generated content and coordination with the copyright holder. according to atlas, the initial impact of ai in higher education is still not fully understood, but it does present an opportunity for professionals to incorporate chatgpt into their workflow to increase efficiency and streamline tasks. atlas advises that a well-thought-out plan with clear goals in mind is crucial when utilizing chatgpt.7 these findings suggest that ai resources such as chatgpt have the potential to improve library cataloging by automating labor-intensive and timeconsuming tasks. moreover, they offer opportunities for professional development resources to ensure that libraries remain up to date with current technologies. methodology to evaluate chatgpt’s potential for library cataloging, i used the chatgpt free research preview version (released february 13, 2023) to generate marc records in rda for various items. when asked about its training data, chatgpt replied: i was trained on a vast amount of data, including examples of marc and rda records, as well as the rules and guidelines for creating these records. my training data includes a wide variety of cataloging resources, such as online guides and manuals, training modules, and real-world examples of marc and rda records. this training allows me to generate accurate and standardized marc and rda records based on the information provided (chatgpt, personal communication, february 23, 2023). while this response was interesting, i wanted to test chatgpt’s claims. i asked it to generate records for six items, including one with no corresponding worldcat entry, and compared the results to records created by human catalogers. five items had existing marc records, while the sixth item was specifically chosen to test chatgpt’s ability to generate an original record. i evaluated chatgpt’s accuracy, efficiency, and ability to handle different types of materials and cataloging/metadata standards, given that chatgpt is known to produce both accurate and inaccurate or misleading information.8 to test chatgpt’s ability to create marc records, i conducted an initial experiment using readily available materials. i asked chatgpt to generate a marc record for the 1996 edition of anne rice’s interview with the vampire9 using rda (chatgpt, personal communication, february 23, 2023). the resulting record is shown in table 1, and i compared it to a record in oclc’s worldcat, which is illustrated in table 2. the results of this test indicate that chatgpt can produce an accurate and effective record for interview with the vampire. information technology and libraries september 2023 from chatgpt to catgpt 3 brzustowicz after this first success, i attempted to generate a marc record for the 2018 vinyl reissue of david bowie’s 1977 album low10 using chatgpt and the rda standard (chatgpt, personal communication, february 23, 2023). the resulting marc record is presented in table 3, which was then compared to professional catalogers’ records. table 4 shows an existing marc record for low in oclc’s worldcat. notable differences were observed between the human-generated and chatgpt-generated marc records, with the chatgpt record lacking foreign-language headings and subject headings in certain fields (6xx). this is not surprising, as such tasks require a degree of personal discernment on the part of the cataloger. these discrepancies spurred me to investigate the applications further. i refined the question to test chatgpt’s ability to generate appropriate library of congress call numbers. for this example, i requested: “generate a marc record using rda that includes library of congress call number for the 1971 german edition of pedagogy of the oppressed”11 (chatgpt, personal communication, february 24, 2023). tables 5 and 6 demonstrate that while chatgpt may not always “choose” the same subject access points or consistently format all relevant fields as effectively as a human cataloger, given proper training and oversight it can be used as an effective supplement to human cataloging. the accurate formatting of field 050 and appropriate “dummy” call number (lb875.p442) further demonstrate this technology’s potential for streamlining cataloging and resource description, given proper training. in this instance, the ai noted that multiple fields would need to be edited: “please note that the control number (001) and the date (005) in the above record are placeholders and should be replaced with actual values when creating the record” (chatgpt, personal communication, february 24, 2023). to further put chatgpt’s abilities to the test, i asked it to generate a citation for the 2018 russian print edition of cixin liu’s the three body problem12 (chatgpt, personal communication, march 2, 2023). this was a more complex request than the previous ones; it required chatgpt to extract and incorporate metadata from a non-latin character set (cyrillic) and in a foreign language. table 7 shows the marc record generated by chatgpt, while table 8 displays the existing marc record for the russian translation of this work found in worldcat. although there were differences between the two records, chatgpt’s output was comparable to the professional catalogers’ work. the discrepancies between the records, however, suggested that chatgpt was not merely reproducing existing records but creating original marc records, as it claimed. the results of this test further demonstrate chatgpt’s potential as a powerful tool for automating the generation of accurate metadata records. during my testing, i discovered that the limited vinyl pressing of alternative rock band mood rings’ 2013 single “pathos y lagrimas”13 had no worldcat entry. to see if chatgpt could generate an original marc record for this item, i asked it, “can you generate a marc record using rda for mood rings’ 2013 single ‘pathos y lagrimas’” (chatgpt, personal communication, march 8, 2023). despite the absence of an equivalent worldcat record, chatgpt was able to provide a sample marc record, which i have included in table 9. this record, complete with sample text for the leader and control fields (00x), serves as evidence of two important capabilities of chatgpt: its ability to generate original cataloging records, and its incorporation of placeholder content in fields that are collection specific. chatgpt’s ability to generate accurate marc records using both rda and ersatz “original” cataloging demonstrates its potential as a cataloging and item description resource. additionally, chatgpt’s versatility is further highlighted by its ability to produce original content in other metadata formats. when asked if it could generate records using the dublin core metadata information technology and libraries september 2023 from chatgpt to catgpt 4 brzustowicz element set, chatgpt not only confirmed its ability but also provided a sample entry for “pathos y lagrimas” as seen in table 10. while some modifications may be necessary to cater to collectionspecific demands, this showcases chatgpt’s potential as a time-saving tool for automating record generation in multiple formats. in addition to its ability to generate accurate records adhering to multiple metadata standards, the results of this study also highlight the potential versatility of chatgpt as a cataloging and item description resource. the model’s ability to generate records for different media and in different languages could prove particularly useful for librarians and other information professionals who manage diverse collections. moreover, while catalogers may need to modify the pregenerated records to suit their specific collections’ requirements, chatgpt’s user-friendly interface and accurate record generation suggest that it could be a valuable tool for improving cataloging workflows and increasing efficiency. with further development and refinement, chatgpt has the potential to significantly enhance the capabilities of information professionals and improve the discoverability of library collections. results this study provides evidence that chatgpt can generate accurate records that conform to multiple metadata standards. the model can extract essential metadata, including title, author, publisher, publication date, subject headings, and other descriptive elements, with precision. additionally, my research reveals that chatgpt’s ability to generate marc records is not limited to specific formats or languages, as it successfully created marc records for various media and materials in different languages, such as english, german, and russian. chatgpt was able to generate both accurate existing authority records and entirely original ones, and it could generate records using both rda and dublin core standards. according to chatgpt, it has been trained on data from various catalogs, including oclc’s worldcat, the library of congress, the national library of medicine, the british library, copac (uk academic and national library catalog), europeana, and the hathitrust digital library (chatgpt, personal communication, march 9, 2023). this poses a unique challenge, as these catalogs may have different policies on access and reuse of their data. for example, oclc’s catexpress is a subscription-based automated cataloging system. if chatgpt or a future “catgpt” draws on oclc’s data and makes it available for free, it may raise questions about oclc’s copyright holdings. additionally, while chatgpt may generate records for materials available on the public internet, such as “pathos y lagrimas,” questions remain regarding how to credit the intellectual labor necessary for creating these records. my comparison of chatgpt-generated marc records against manually created records by professional catalogers had positive results. while the accuracy of the chatgpt-generated records was comparable to those of the manually created records, notable differences existed in how subject access points were assigned. this suggests that chatgpt has the potential to provide new methods for growing the discipline of library cataloging by automating the more rote, laborintensive and time-consuming tasks (for example, copy cataloging). in future studies, it may be of interest to the discipline to further test the applications of ai-generated marc records on a catalog-wide scale. while chatgpt has the potential to streamline aspects of the cataloging process, it is not a complete replacement for human catalogers. the records generated by chatgpt can serve as effective starting points, but they often contain discrepancies when compared to professional information technology and libraries september 2023 from chatgpt to catgpt 5 brzustowicz catalogers’ records. for example, while the placeholder text in fields 001 and 005 can be useful, it may not match the formatting standards used by specific library collections. nonetheless, chatgpt-generated records can be accurate and effective in classifying information that is not specific to any collection, such as call numbers. bias while chatgpt shows promise as a tool for generating marc and dublin core-style records, it is also limited by its training data. at present, chatgpt searches public records (e.g., worldcat). as a result, any records it generates will draw on existing professional catalogers’ records. if a record is incomplete or contains bias—even via omission—then chatgpt will reflect those biases in its output. this will necessitate close monitoring of both original records and those which chatgpt has created through virtual copy cataloging. chatgpt’s ability to copy and generate records is rooted in its machine learning-based understanding of cataloging and metadata standards. this ai system uses training data from oclc’s worldcat to generate records, which means that the quality of the generated records is dependent on the quality and comprehensiveness of the training data.14 biases or limitations in the training data can result in biased or incomplete records. for example, if the training data is restricted to certain regions, languages, or publishers, the generated records may not reflect the full diversity of a library’s collections. similarly, biases in subject headings, descriptors, or other fields in the training data may also manifest in the generated records. while chatgpt itself has no biases, it is possible for biases to be introduced through the training data, which makes it essential for librarians and other information professionals to curate and update the data regularly. to address these potential biases, information professionals training a large language model should curate the training data carefully and periodically review and update it to ensure it is comprehensive, representative, and unbiased. they may also need to manually review and edit generated records to correct any biases or inaccuracies identified. this approach would provide new opportunities for the profession to highlight diversity, equity, and inclusion in the development and use of ai. while an ai may not have biases, biases of the people involved in training and applying the ai could affect the generated content. like other machine learning models, chatgpt acquires its biases from external sources as it can only respond to the data it has been trained on, which may reflect human errors or intentions. therefore, while chatgpt could streamline and improve the record generation process, information professionals should approach its use with awareness of its limitations and potential biases. to ensure the accuracy, comprehensiveness, and fairness of the generated records, information professionals should take proactive measures to mitigate any biases and errors . discussion the results of this study have significant implications for library cataloging. the ability to accurately create descriptive records using chatgpt could significantly reduce the time and resources required for copy cataloging; this could free up library workers to focus on other important tasks, such as collection development, user services, and metadata management. moreover, chatgpt could improve the accuracy and consistency of records in library catalogs. as chatgpt follows established cataloging rules, records created by the model are less likely to contain errors or inconsistencies; this could lead to improved search and discovery experiences for library users, as well as better interoperability between library catalogs and other systems. information technology and libraries september 2023 from chatgpt to catgpt 6 brzustowicz the intellectual property concerns surrounding chatgpt’s ability to generate content are multifaceted. one concern is the potential for copyright infringement, as chatgpt’s detailed descriptions of original works may be too like the originals, leading to legal issues for those who use the generated content without proper attribution or permission. this concern is particularly heightened for copyrighted works like books or music, where even small portions of the work can be protected. therefore, it is crucial for chatgpt’s output to be thoroughly reviewed and vetted before being used in any public-facing materials. another concern is the possibility of misattribution of authorship. chatgpt’s use of dublin core to describe original works could lead to disputes over ownership and potentially even legal action if it generates a description that attributes authorship to the wrong person or entity. to prevent such conflicts, information professionals should ensure that the metadata generated by chatgpt accurately reflects the authorship and ownership of the original work. this can be done by reviewing and editing chatgpt’s output to ensure that the metadata is correct before it is shared publicly. the ownership of the generated content is also a concern, as it is not clear who owns the content created by chatgpt. as a machine learning model, chatgpt generates content based on the data it has been trained on, raising questions about the ownership of the content it produces. establishing clear guidelines for ownership and use of the generated content can help avoid any potential disputes over ownership and ensure that appropriate attribution and permissions are obtained; this is particularly important given the potential commercial value of the content that chatgpt can produce. furthermore, it is essential to consider ethical and legal implications of the generated content, such as data privacy and protection, and to ensure that these concerns are addressed when designing guidelines for ownership and use. finally, there is the potential for unintentional disclosure of sensitive or confidential information. chatgpt’s ability to generate detailed descriptions of original works may inadvertently disclose unpublished findings or proprietary information, potentially causing harm to the author or institution. to mitigate this risk chatgpt’s output must be carefully reviewed and edited to ensure that it does not inadvertently disclose sensitive information. implementing appropriate data security measures and access controls may help prevent unauthorized access to sensitive information. conclusion the study demonstrates that chatgpt has the potential to significantly streamline the cataloging process in libraries by generating accurate and consistent records for a diverse range of materials. however, it should be used as an auxiliary tool in conjunction with human cataloging efforts to ensure the highest level of accuracy and impartiality. regular monitoring and evaluation of the model are necessary to detect any potential biases or limitations in the training data. by applying a careful and considered approach to its use, librarians and other information professionals can leverage chatgpt to enhance the efficiency and effectiveness of cataloging processes, ultimately benefiting library and information center patrons. the accurate and comprehensive marc records produced by chatgpt highlight its potential to enhance the effectiveness of library cataloging systems. by extracting metadata information such as author, publisher, subject headings, title, and other descriptive components with high precision, the technology can improve the search and discovery experience for library users. as with any machine learning model, though, there is a risk of bias that needs to be considered when utilizing information technology and libraries september 2023 from chatgpt to catgpt 7 brzustowicz chatgpt. therefore, it is crucial to monitor and evaluate the training data used to build the model, to ensure that it is extensive, impartial, and representative. the use of dublin core to describe original works is another factor that should be taken into consideration when using chatgpt for cataloging. the model’s potential to generate accurate metadata records is reliant on the quality of the input data, including the use of standardized vocabularies like dublin core. the use of any metadata standard, such as dublin core, may introduce biases and errors that could affect quality of chatgpt-generated records. therefore, information professionals should ensure that the metadata standards used by chatgpt are appropriate for the materials being cataloged and that the resulting records are regularly reviewed and evaluated for accuracy and impartiality. chatgpt’s accurate and comprehensive metadata records have the potential to enhance the effectiveness of library cataloging systems and improve the search and discovery experience for library users. however, as with any machine learning model, there is a risk of bias that needs to be considered when utilizing chatgpt. to ensure error-free results, librarians and other information professionals should approach chatgpt’s application systematically, by monitoring and evaluating the training data used to develop the model’s capabilities and by regularly curating and updating those data. additionally, periodic inspection and amendment of the generated records may be necessary to avoid inaccuracies and discrepancies arising from biases in the training data. by taking a careful and deliberate approach to chatgpt’s use, we can ensure that the resulting metadata records are as accurate, comprehensive, and unbiased as possible, while also being mindful of the intellectual property considerations inherent in using a machine learning model to generate content. information technology and libraries september 2023 from chatgpt to catgpt 8 brzustowicz tables table 1. chatgpt-generated marc record for the 1996 reprint of interview with the

what do you mean by that? m wuah ha ha ha haaa! finally it’s my turn. i hold the power of the editorial. (can you tell i’m writing this around halloween?) seriously now, i’ve been intimately and extensively involved with information technology and libraries for eleven years, yet this is the first time i’ve escaped from behind the editing scenes to address the readership directly. as managing editor for seven of the eleven volumes (18–22 and 27–28) and an editorial board member reviewing manuscripts (vols. 23–26), i am honored marc agreed to let me be guest editor for this theme issue. this issue is a compilation of presentations from the discovery mini-conference held at the university of nevada las vegas (unlv) libraries in the spring of 2009. the first article by jennifer fabbi gives the full chronology and framework of the project, but i have the pleasure of introducing this issue and topic by virtue of my role as guest editor, as well as my own participation in the miniconference before i left unlv in july 2009. n what is discovery? when the dean of libraries, patricia iannuzzi, announced that unlv would have a libraries-wide, poster-session style discovery mini-conference, jennifer fabbi and i decided we wanted to be part of it. we had already been exploring various aspects of discovery as part of an organizational focus as well as following up on a particular event that happened earlier in the year. while serving on a search committee, we posed a question to all the candidates: “what do you see the library catalog looking like in the future? what do you see as the relationship between the library catalog and other access or discovery tools?” one of the candidates had such a unique answer that it got us thinking: are we all talking about the same thing when we discuss discovery? the mini-conference gave us the opportunity to explore the idea further. an all-library summit that preceded the mini-conference announcement had focused on users finding known items. we knew that discovery was so much more and that it depended on the users’ needs. of course, first we went to multiple online dictionaries to look up the meanings of “discovery” and found the following definitions: n something learned or found; something new that has been learned or found n the process of learning something; the fact or process of finding out about something for the first time n the process of finding something; the process or act of finding something or somebody unexpectedly or after searching we also looked at famous quotes about discovery. there were some of our favorites: a discovery is said to be an accident meeting a prepared mind. —albert szent-gyorgyi education is a progressive discovery of our own ignorance. —will durant next, a colleague recommended we look at chang’s browsing theory.1 this theory covered the broad spectrum of how users seek information and showed a more serendipitous view than the former focus of known item search. obviously, browsing implies a physical interaction with a collection, so we reframed the themes to fit discovery in the “every-library” electronic information environment. chang’s five browsing themes, adapted to discovery: n looking for a specific item, to locate n looking for something with common characteristics, to find “more like this” n keeping up-to-date, to find out what’s new in a field, topic or intellectual area n learning or finding out, to define or form a research question n goal-free, to satisfy curiosity or be entertained.2 all interesting information, but a little theoretical for a visual presentation. to make these themes more concrete and visual, i suggested we apply them to personas as described in one of my favorite books, the inmates are running the asylum.3 this encourages programmers to create a user with a full backstory and then design a product for their needs. to do this in an entertaining way, we identified five types of users we’ve encountered in our libraries and described an information-seeking need for each. i then created some colorful and representational characters using a well-known, alliteratively named candy’s website. our five characters were 1. mina, stylishly dressed and always carries a cell phone, is an undergraduate who rarely uses the library. she has a sociology class library assignment to find information on the cell phone habits of generation x. 2. ms. lvite lives in the las vegas area and contributes to the

into the five themes of discovery. jennifer and i expected certain placements and were pleasantly surprised when our attendees challenged our assumptions with alternate possibilities. another section of the poster related discovery behaviors to specific electronic discovery tools. we provided a few and asked the attendees to add others (see table 1). while talking with each attendee, we provided a bookmark listing the five discovery behaviors (with colorful character personas) and suggested they keep them in mind as they visited the other conference sessions. we challenged them to identify what user behaviors the other presenters’ systems or services were targeting. the message jennifer and i hoped to convey with our poster was this: the way we think about discovery, or the users’ goals in

describes his work with free screen capture tools to build pathfinders to promote resource discovery. patrick griffis and cyrus ford each looked at enhancing catalog records, so they combined their

watson (corresponding author: apwatson@olemiss.edu) is research & instruction librarian and associate professor, university of mississippi © 2023. submitted: may 27, 2022. accepted for publication: october 12, 2023. published 18 december 2023. abstract to promote an academic library makerspace, the university of mississippi libraries hosted a “3d selfie” booth which used body scanning technology. this booth, advertised on campus and set up outside the library during the first weeks of class, was designed to attract attention and perform outreach through the use of body scans to be printed in the makerspace at a later date. although the hoped-for printing of “selfies” did not materialize, the project resulted in data about interested patrons and ideas for similar projects going forward. this paper serves as a case study for other academic library makerspaces interested in similar outreach. introduction the idealab, a makerspace in the j. d. williams library at the university of mississippi, opened in 2017. as a part of outreach efforts designed to increase awareness of and excitement for this makerspace, library staff created and ran a pop-up “3d selfie” booth in august 2018 during the first weeks of the fall semester. library staff focused on advertising 3d body scanning technology and using the term “3d selfie” to generate enthusiasm for the makerspace with the hope that students might spend time at an associated booth or even visit the makerspace in person to obtain a 3d print of their selfie, with “3d selfie” being the term they were marketed under as opposed to the more accurate, but less catchy “3d image” or “3d scan.” as such, the library collected data from participants who agreed to be scanned during the four days the booth was in operation. ultimately, library staff sought to use this unique concept and technology to generate buzz and harvest data for future maker-specific outreach efforts in addition to the makerspace’s already extant workshops. while the hoped-for result of a large number of selfies being printed in the idealab was not achieved, the outcome is still interesting and offers lessons for the university of mississippi—as well as any other academic library makerspaces interested in running “3d selfie” booths—going forward. literature review makerspaces in libraries, and academic libraries in particular, have been an important and growing area of discourse. relatively little has been written about outreach undertaken for these spaces since their inception as a trend in the early 2010s, though, and what scholarship exists tends to focus on programming and workshops rather than bespoke outreach. wallace et al. provide a variety of approaches to programming and workshopping, for instance.1 similarly, the mailto:apwatson@olemiss.edu information technology and libraries december 2023 to thine own 3d selfie be true 2 watson literature is heavily skewed toward 3d printing over 3d scanning, and many articles on scanning seem to focus on the utility of scanning and printing rare or delicate items in special collections or similar contexts. passehl-stoddart et al. provide an example of this form of makerspace outreach, in this case 3d printing of cultural objects from a local collection.2 one of the earlier scholarly treatments of 3d printing and scanning in an academic library was michael groenendyk and riel gallant’s work at dalhousie university in 2013, near the dawn of the current maker movement.3 writing about the dalhousie “hackerspace,” which predated even the term “makerspace” being in wide use, groenendyk and gallant described the technical details of their setup for a 2013 audience before writing frankly about their outreach efforts and difficulties with 3d scanned models.4 their 3d printer and 3d scanner were placed at the main desk on the library’s first floor to allow staff supervision, and with a booking system in place, the high traffic and visibility of the main desk location served to promote these services at a basic level, with the library hoping to engage in more direct outreach to specific departments later on.5 this is similar to the university of mississippi’s first library 3d printer, which was kept behind a desk and strictly mediated. the dalhousie librarians cited “trying to print 3d models that were not designed with 3d printing in mind, or by users with no knowledge of how 3d printing works” as their largest challenge, resulting in many unprintable files and the need for library staff to offer guidance and other interventions to avoid wasted resources.6 they found that, in particular, user inexperience with the 3d scanning software coupled with the relative difficulty of making a “fully formed and realized” 3d scan led to unrealistic user expectations for the timeliness and quality of their scans.7 positioning the object to be scanned, layering different scans together into a composite, and filling holes caused by missing scan data—all problems that still existed as of 2018, albeit somewhat moderated by new technology—were cited as particular difficulties with the nextengine 3d scanner used at dalhousie.8 the very first experiments in 3d scanning at the university of mississippi, when only a microsoft kinect video game scanner/controller was available, faced similar problems and prevented an early rollout of 3d scanning technology. a year later, in 2014, jason reuscher proposed 3d scanning as a library public service at penn state’s schuylkill campus with the same nextengine 3d equipment, reasoning that “academic libraries generally offer two-dimensional (2-d) or flatbed scanning to their patrons—why not 3-d scanning?”9 penn state went a step further than dalhousie in introducing mobility into the mix; their 3d scanner was able to be checked out, though initially limited to the building and requiring an attached laptop and auto-rotating platform.10 reuscher noted in particular that the device had a strong word-of-mouth outreach component; though only a few preliminary scans and workshops had been held by 2014, news of the scanner had spread far beyond schuylkill and sparked intense interest from other penn state affiliated students and faculty and created difficulties for those who wished to use it from distant campuses.11 reuscher, uniquely, advocated separating 3d printing from 3d scanning in terms of infrastructure as a library public service, similar to the way the university of mississippi sought to unencumber the scanner from the printer for outreach and promotional purposes.12 beginning in 2014, and through a 2017 revision of his book, jason griffey was beginning to realize some of the possibilities inherent in 3d scanning in library settings, dedicating a portion of a book chapter to various devices capable of doing such.13 in addition to turntable-style scanners, which mirror the rotating platform used by reuscher, griffey also addressed wireless handheld scanners and included an image of a 3d systems sense scanner being used to create a bust scan of a human information technology and libraries december 2023 to thine own 3d selfie be true 3 watson model, similar to some early experiments undertaken at the university of mississippi.14 while the issues that griffey cites, such as difficulty scanning color-contrasting areas, were less of an issue in 2018–2019 than in 2014, and prices for the scanners themselves have plummeted, he is prescient in seeing the potential of the scanners to be used for outreach by creating “really interesting and useful things from a scanner.”15 griffey’s enthusiasm for the idea is palpable as he goes on to say that portable scanners like the sense are “far more interesting ... in that [they allow] you to scan absolutely arbitrary objects rather than being limited to things that will fit onto a turntable ... you can scan freestanding objects, people, parts of rooms—nearly anything.”16 in particular, griffey was excited about the sense scanner that worked with an apple ipad, calling it a “an excellent and truly portable solution”—exactly what the university of mississippi found a similar ipad-based product to be in its 3d scanning outreach efforts.17 in 2015, ann marie lynn davis sought to do an analysis of academic library makerspace technology in a particular region—new england—through a brief survey and literature review. davis found that eight of the responding academic libraries had makerspaces, with six of them possessing some form of 3d scanner, including both handheld models and microsoft kinects.18 davis mentioned one library staff member in particular who was highly invested in 3d scanning at an institution that did not have a formal makerspace but planned to establish one in the future; this person had participated in a university museum 3d printing day, both serving as an “expert panelist” and “giving public demonstrations on library-owned 3d printers and a scanner kinect bar.”19 both in using a kinect scanner as an early-stage 3d scanner and in using 3d scanning to advertise 3d printing services, this library staffer at an unnamed institution demonstrated striking parallels to the university of mississippi. also in 2015, megan lotts described a number of “participatory events, which essentially are popup making spaces,” including a 2d selfie booth at the university of virginia, primarily as stress relief.20 these pop-up makerspaces can be “easily put up, taken down, sent from one library to another, and they use little space for storing materials.”21 emphasizing their outreach aspects, lotts noted that “making events can bring positive attention to the library and invite patrons to share their skills and talents.”22 pushing the idea of academic library outreach with 3d scanning technology even further, erich purpur at the university of nevada reno performed an internal “pop-up maker technology outreach event” with the intent of allowing staff from a large library system to lay hands on makerspace technologies, get an introduction to 3d printing, and develop adobe cs6 literacy.23 with over 150 librarians and staff available to attend, purpur attracted 40 attendees, with surveyed attendees responding favorably to the event’s effectiveness.24 the unr librarians also noted that “… faculty and staff regularly take [their] maker technology on the road engaging with both the university and greater reno communities at a variety of events … these outreach and engagement efforts have repeatedly proven to be successful, prompting the consideration of their possible use as part of internal professional development and outreach.”25 these maker technology roadshows are similar to what the university of mississippi attempted, especially the “internal pop-up maker outreach event,” albeit with a different user group as its focus—library staff at reno, patrons at mississippi. finally, jennifer grayburn and ammon shepherd spoke to the overriding need for outreach in academic library makerspaces in 2017. writing for the 2nd international symposium for academic makerspaces, the authors found that what they called a “build it and they will come” mentality did not always apply satisfactorily in academic settings.26 “while many users are information technology and libraries december 2023 to thine own 3d selfie be true 4 watson familiar with making through their academic studies or personal interests, many faculty and students have never encountered these technologies or methods, let alone thought critically about the relevance of making for their own research,” they wrote, adding that “... this unfamiliarity and even confusion about the purpose of a makerspace and how it is used might create the sense that a makerspace is not open or relevant to everyone.”27 while citing outreach efforts such as themed programs and project-based workshops as possible ways for academic libraries to attract makers, they noted that the “apparent irrelevance” of academic makerspaces was a “major barrier-to-entry for faculty and students who might otherwise benefit academically from critical making and the resources found in a makerspace.”28 continuous outreach and engagement by makerspace staff, they argued, was the only solution, taking the form of traditional outreach and other nontraditional forms of collaboration and publication such as blogging.29 the picture that emerges from this timeline of scholarship is one of academic libraries with makerspaces experimenting with outreach and 3d scanning but very rarely combining the two in a pop-up event. with this in mind, a case study of using 3d scanning from an academic library makerspace for outreach purposes seems both warranted and timely. background the university of mississippi libraries (uml) acquired its first 3d printer in late 2016 and began assembling a makerspace in mid-2017 once sufficient space had been allocated. uml populated the makerspace area—which was dubbed the idealab—with a 3d printer, a 3d scanner, a largeformat printer, arduino circuit prototyping kits, soldering irons, sewing machines, snap circuits, lego mindstorms, and a variety of other tools. the available location in the library was large and versatile but did not receive a great deal of foot traffic and was missed by many patrons due to its location and some architectural quirks in the design of the older part of the main uml building. this lack of foot traffic to the idealab, combined with the lack of a full-time staffer to run the makerspace, led to a general lack of awareness of the space and its contents among university patrons and community stakeholders. since the idealab had been conceptualized as a service the library felt would be useful and a future growth area, this represented a problem. once a full-time staffer was hired for the idealab in summer 2018, uml turned to the problem of trying to raise campus awareness of the makerspace during the first few weeks of class, when many new students would be on campus but before most major assignments and tests were scheduled. through a series of brainstorming sessions, uml staff decided to open a tent on the trent lott plaza, a major thoroughfare in the center of the university of mississippi’s campus, around lunchtime for four days across two weeks: august 22–23 and august 27–28, 2018. a variety of other campus organizations had booths, tables, or tents in the trent lott plaza, and foot traffic through the area was anticipated to be high. the setup was similar to that used by purpur at the university of nevada reno in its internal staff-only pop-up, with the addition of a public demonstration concept similar to that reported by davis in new england.30 uml could have simply advertised the idealab at this tent, but during the brainstorming sessions, the idea emerged that perhaps the advertising should focus on a single technology to build interest. the expectation was that a sufficiently new and exciting technology would have a “halo effect” for the idealab as a brand: by seeing an interesting and exciting makerspace technology, students, faculty, and staff might be more apt to visit the booth or the idealab itself, even if they never used the technology that initially intrigued them. the idea of a halo effect, that a positive impression created by one part of a makerspace—the 3d selfies—would influence positive information technology and libraries december 2023 to thine own 3d selfie be true 5 watson opinion for the other parts—the remainder of the idealab and its equipment—is borrowed from psychology, where the term has been in use for nearly a century.31 as the oldest and most mature technology in the idealab, the 3d printer seemed like an ideal candidate for this halo effect—several library staff members knew how to use it and there had been a great deal of hands-on experimentation with the system since its acquisition nearly two years prior. however, participants in the brainstorming sessions also felt that a simple “3d print petting zoo” composed of preprinted objects would not be dynamic enough to attract interest. the desired effect was, instead, akin to that reported by reuscher at penn state’s schuylkill campus: strong interest carried by word-of-mouth.32 3d body scanning was the next option that the brainstorming suggested. an early form of 3d body scanning had been devised by one of the authors in late 2016, consisting of a microsoft kinect for windows sensor and a freeware product called reconstruct.me. this 3d scanning, which could only capture the head and shoulders for the purposes of making busts, had generated considerable attention at the library’s 2016 holiday party, where a 3d selfie booth had been set up. a later demonstration to the friends of the library (fol) executive board in mid-2017 had been met with a similar positive reaction. even though the scans were limited to busts and to a single color with no surface texture mapping, the enthusiastic response among uml staff and the fol board showed a strong impression. this response was very similar to the results reported by davis in new england in a survey conducted in roughly the same time frame.33 figure 1 shows one of the early prototype busts created using this basic scanning rig. figure 1. an early 3d selfie bust made with windows kinect and reconstruct.me. at the same time, the idealab had been in the middle of a procurement process to acquire and implement an improved 3d body scanner. the prototype kinect-based unit had been large, bulky, required an external computer and power source, and could only scan a limited part of the body. by late 2017, the library had acquired an occipital structure 3d scanner, which offered a superior option. the occipital structure clipped to an ipad, was powered by the ipad’s internal batteries, and allowed scans to be immediately emailed or uploaded to a cloud drive. the new unit also allowed for full body scans to be easily created, as well as texturing, even though the library 3d printer—a lulzbot taz 5—was only capable of printing in a single color. information technology and libraries december 2023 to thine own 3d selfie be true 6 watson the brainstorming group therefore decided that the idealab makerspace tent would be advertised as a “3d selfie” booth, allowing for a short and catchy message in advertising that showcased an exciting new technology that provoked the halo effect and lead more traffic to the idealab’s physical space. the group also considered that, by giving patrons something to print on the 3d printer that was unique and personalized, those patrons would be encouraged to come to the idealab to see their selfies printed out. by collecting some basic demographic information from the patrons at the time of the selfie scans, the uml could also see which campus group or groups were most interested in the technology, allowing further targeting and customization of the outreach message. methods in the weeks before august 22, 2018, uml employees advertised the 3d selfie booth across all available library channels. this included the library’s official social media pages, physical flyers pinned to bulletin boards, emails sent to campus listservs, and a daily reminder in university of mississippi today—the university of mississippi’s daily email event calendar. an example of a 3d selfie booth release form may be seen in appendix a. beginning august 22, 2018, a working group of three uml employees—one faculty member and two staffers—assembled the materials for a tent to be pitched in the trent lott plaza of the university of mississippi. the uml-branded tent was already owned by the uml and was primarily used for a library presence at tailgating events before major home football games. due to the need for consistent lighting in order to allow the occipital structure 3d scanner to work properly, all scanning was done beneath the tent. the tent was also situated near enough to a major university building to be able to receive a wireless signal, which was essential to the 3d scanner’s functionality. the first day—august 22, 2018—the tent was erected in the middle of the trent lott plaza just outside of weir hall, near the geographical center of campus. difficulties with glare, distance from power outlets, and other issues led the tent to be moved beneath a large tree at the east entrance to the plaza for the remaining three days—august 23 and august 27–28, 2018. figure 2 shows the library tent with 3d scanning of patrons in progress. information technology and libraries december 2023 to thine own 3d selfie be true 7 watson figure 2. the library’s 3d selfie booth. with the area under the tent dedicated to taking the 3d selfies, several tables were set up directly adjacent to it. these tables were managed by a uml staff or faculty member and contained a variety of technology from the idealab on display. items included the aforementioned “petting zoo” of interesting objects created on the 3d printer during its testing and proving period—things information technology and libraries december 2023 to thine own 3d selfie be true 8 watson such as a 3d-printed printing press capable of rolling small inked images onto paper, a 3d-printed shadowbox that seemed opaque but would cast a shadow that revealed a picture, a bust from the earlier prototype 3d scanner, and several other small widgets. other technology on display included an arduino software prototyping kit, a makey-makey input device, and a large-format printer image that doubled as an advertising billboard. library promotional materials, including handheld fans and idealab flyers, were made available at the tables. in order to prevent any issues regarding usage of the 3d selfies for research, uml staff prepared a photo and video release form to collect patron consent. the back of the form served as the demographic information collection survey, asking a variety of questions useful to future uml library promotions and events. information collected included school status (undergraduate, faculty, etc.), whether or not patrons had visited the physical idealab, a question about how the patrons knew about the 3d selfie booth, two questions gauging future interest in the idealab and uml resources, and a final question asking which—if any—social media platform(s) the patrons used to follow uml. for the purposes of this survey, an older library resource was also included: studioone, a one-button recording and editing studio. this was done because studioone fell under the jurisdiction of the idealab staff despite being in a separate location. a full copy of this form can be found in appendix b. once the 3d selfie was complete, it was shown to the patron and they were given the option of receiving a copy of the scan through email. patrons were also told to come to the idealab for assistance in printing their 3d selfies, if desired. figure 3 shows a completed 3d selfie, taken of the first patron in figure 2. figure 3. a 3d selfie taken at the library’s booth. the student signed a release form for this purpose. note that there are some 3d artifacts present around the periphery where the scanner picked up miscellaneous items like the legs of the tent; these would have been removed using a 3d image editor before printing. the 3d model is also textured in full color, which works as a digital artifact but which cannot be reproduced on the library’s lulzbot taz 5, which was limited to monochrome printing at the time. information technology and libraries december 2023 to thine own 3d selfie be true 9 watson data a total of 112 patrons stopped by the library tent during the four days it was in operation. of those 112 patrons, a total of 29 (approximately 26%) had a 3d selfie made with the library scanner. this includes several patrons who had 3d selfies taken together with friends or loved ones but excludes the test scans made by library workers on-site to test their equipment. table 1 shows the breakdown in the number of patrons and selfies per day, as well as the conversion rate, or the percent of visitors who had 3d selfies taken. table 1. patrons, 3d selfies,

fewest number of visitors and selfies, while the final day had the best conversion rate, nearly double that of the next best day. aside from the very high conversion rate on the final day, the other three days had very similar rates. the number of visitors on the final three days were also broadly similar. of the 112 patrons who visited the library booth for long enough to be counted, only the 29 who had 3d selfies taken completed the full demographic survey form, as had been the original plan. tables 2–5 show highlights of this demographic data; the complete responses are available in appendix c. table 2. patrons by school status school status patrons percent undergraduate 20 68.97% graduate 6 20.69% faculty/staff 3 10.34% undergraduates were by far the largest patron group, with

interest in using either or both after the event, and those nine patrons indicated “maybe.” no patrons claimed to be uninterested in either or both spaces. table 4. how patrons found out about the 3d

mississippi’s daily email event calendar. very few cited flyers or the uml website. of those listing “other,” two cited friends, one cited facebook, one cited a departmental listserv, and three others

facebook 2 instagram and twitter 0 facebook and twitter 0 none of the above 13 do not use social media 3 of the patrons who had 3d selfies made, 13 followed uml on at least one social media platform. thirteen others did not follow uml on any of the listed platforms, while two others were not social media users of any sort. finally, of the 29 patrons who had 3d selfies made, only one later stopped by the idealab to have it printed on the uml lulzbot taz 5 machine. discussion while a relatively large number of people visited the uml 3d selfie booth during its four days of operation, nearly three-quarters of them did not have a 3d selfie made. based on the anecdotal experience of the library staff members running the booth, there appeared to be several reasons for this relatively low conversion rate. with only three staffers and one scanner, it could take 5–10 information technology and libraries december 2023 to thine own 3d selfie be true 11 watson minutes to create a single scan, meaning that there was occasionally a line or interested patrons that declined in the interest of time. many passersby who did not stop also cited lack of time— often needing to walk to classes across campus. according to anecdotal observations from uml staff, several people also showed interest in the technology, stopping to chat with uml staff and look at the idealab equipment on display, but declined to have a 3d selfie made. a variety of factors may have been behind this, from a simple reluctance to be photographed, to genuine interest in the other technologies on display, to a desire to take a free uml-branded fan on a hot summer day. it seems clear that some of the assumptions made by the uml brainstorming group were incorrect. only one of the 29 patrons was interested in having a 3d print of their selfie made, for instance—this did not seem to be a strong inducement for the patrons to visit the idealab. as far as could be determined, this student did not follow through on their interest and print their selfie. based on discussions the patrons had with uml staff, some patrons seemed to be more invested in their scans as digital objects rather than physical models—they wanted the scan but not necessarily the print. one patron spoke of using their scan to create user profile pictures for gaming sites, for instance, and another wanted to use the texture mapping from the scan— available as a separate file—to put their face on a video game avatar. the location and timing of the 3d selfie booth also seems to merit further consideration. looking at the patron data, the first day had far fewer patrons and 3d selfies while the remaining three are much more consistent. this may reflect the change in location between the first two days, from a hot and exposed location in the middle of the trent lott plaza to a much more shaded area at its east end. the choice of lunchtime for the booth may also have affected the ability of passersby to stop and engage, since students, faculty, and staff may not have been able to sacrifice their lunch hour to experimenting with library technology. nevertheless, most patrons who stopped for any length of time seemed impressed by the 3d selfie apparatus and the petting zoo of 3d objects. as such, while the hoped-for halo effect may not have led to many patrons coming to the idealab to have their 3d selfies printed, it did seem to open the door for more engagement with the space. due to the space that the 3d selfie booth occupied, it was not surprising that nearly 70% of patrons were undergraduates—the trent lott plaza is one of three primary routes from east to west on the university of mississippi campus and lies adjacent to the business and accountancy schools. choosing a similar high-traffic location would seem to be a good way to entice walk-up patrons, especially considering that almost 40% of the patrons who got 3d selfies were walk-ups. the effect of library staff verbally advertising the tent cannot be understated, as well. hardly any of the patrons had used the idealab or studioone before having a scan made. in the case of the idealab, that was unsurprising—it had only been open with a full-time staffer for a few months at that time. studioone had been open for much longer, several years, and had seen relatively steady use, but due to the fact that it was a separate location in the library, its inclusion on a survey otherwise focusing on the idealab may have confused respondents. patrons may also have been familiar with the spaces but not their names, or had thought that they needed to use both, rather than either, to answer affirmatively. in retrospect, the inclusion of studioone on the survey may have been a mistake—none of its technology was represented on the table, in the petting zoo of 3d objects, or in the promotional materials. information technology and libraries december 2023 to thine own 3d selfie be true 12 watson responses to the other survey questions were encouraging—when asked, the patrons getting 3d selfies seemed very open to the possibility of using library technology and learning about library resources based on their responses. however, this may have partly been because of a selfselecting bias; patrons who were more drawn to technology may have been more likely to take a 3d selfie and therefore answer the survey. ideally, in the future, surveys would be provided to all participants to rule out any such inaccuracies. it is also worth noting that a fair percentage of the patrons who stopped followed uml on some variety of social media—despite very few saying that they had learned about the 3d selfie booth from social media. this suggests that many of the patrons that responded to the selfie booth were already predisposed to engage positively with uml, even if they did not follow it closely enough to cite library social media as the primary thing bringing them to the 3d selfie booth. library staff were also impressed with the number of patrons who cited university of mississippi today as the source of their information about the event—anecdotally, many in the library claim that no one reads the daily emails. clearly, this is an assumption that the data has challenged. thus far, further attempts to iterate on the 3d selfie booth have failed due to circumstance. in 2019 and 2021, the lab’s head left the institution, resulting in a vacancy that precluded any major new initiatives. the uml campus was closed during most of 2020 and had restrictions for part of 2021 due to the covid-19 pandemic as well. conclusion ultimately, the 3d selfie booth did not work entirely as intended. since only one patron had their selfie printed, there was no real way to track how many patrons who were intrigued by the idealab actually made it to the makerspace in person. the way the questionnaires were organized, the format of their questions, and the fact that they were only given to people who had scans made are all factors that make the data susceptible to self-selecting bias. the small number of patrons overall also makes it dangerous to generalize much from the data set. ideally, any future iterations of the 3d selfie booth would have a questionnaire that is altered to reflect a smaller sample size, to be better organized, and to remove references to superfluous resources. the 3d selfie booth did succeed in attracting a large amount of foot traffic and interest; however, 112 individuals across four days, with nearly 30 being engaged enough to go through the lengthy scanning process, compares favorably to many other library events and activities that uml has held. the hoped-for halo effect of patrons being intrigued by the 3d scanning technology did seem to be at least partially true, even if this did not translate into actual 3d prints as expected. a microsoft kinect for windows costs $50–$75, while an occipital structure sensor costs $399 new. given the costs of the tools involved, and the fact that a 3d printer did not seem to be integral to the process, it seems like a 3d selfie booth may be a possibility for other makerspaces looking to drum up interest. the strategy of putting it in a high-traffic area seems to be sound, especially if library staff is available to manage the booth for more than four days per semester. the experience that uml has had with its 3d selfie booth serves as a case study to other makerspaces attempting a similar promotion, both in refining the general idea to be more effective, questioning assumptions about the process, and avoiding some of the pitfalls. information technology and libraries december 2023 to thine own 3d selfie be true 13 watson appendix a: release form the university of mississippi photo & video release

electronic book markup framework, epub 3—yet i have a hard time recommending it, especially if you're an epub novice like me. so much of the book assumes a familiarity with epub 2. if you aren't familiar with this version of the specification, then you will be playing a constant game of catch-up. also, it's clear that the book was written by multiple authors; the chapters are sometimes jarringly disparate with respect to pacing and style. the book as a whole needs a good edit. this is surprising since o'reilly is almost unifo rmly excellent in this regard. the first three chapters form the core of the book. the first chapter, "package document and metadata," illustrates how the top level container of any epub 3 book is the "package document." this document contains metadata about the book as well as a manifest (a list of files included in the package as a whole), a spine (a list of the reading order of the files included in the book), and an optional list of bindings (a lookup list similar to the list of helper applications contained in the configurations of most modern web browsers). the second chapter, "navigation," addresses and illustrates the creation of a proper table of contents, a list of landmarks (sort of an abbreviated table of contents), and a page list (useful for quickly navigating to a specific print-equivalent page in the book). the third chapter, "content documents," is the heart of the core of the book. this chapter addresses markup of actual chapters in a book, pointing out that epub 3 markup here is mostly a subset of html5, but also pointing out such things as the use of mathml for mathematical markup, svg (scalable vector graphics), page layout issues, use of css, and the use of document headers and footers. after reading these first three chapters, my sense is that one is ready to dive into a markup project, which is exactly what i did with my own project. that said, i think a reread of these core chapters is due, which i intend to do presently. the rest of the book is devoted to specialty subjects such as how to embed fonts, use of audio and video clips, "media overlays" (epub 3 supports a subset of smil, the synchronized multimedia integration language, for creating synchronized text/audio/video presentations), interactivity and scripting (with javascript), global language support, accessibility issues, provision for automated text-to-speech, and a nice utility chapter on validation of epub 3 xml files. of these, the chapter on global language support i found to be fascinating. for us native english speakers, it's not immediately obvious some of the problems one will inevitably encounter when trying to create an electronic publication that can work in non-western languages. just consider languages that read vertically and from right to left, for one! as an epub novice, my greatest desire would be for the book to provide, maybe in an appendix, a fairly comprehensive example of an epub 3 marked -up book. maybe this is a tall book reviews 45 order? nevertheless, i would love to see an example of marked up text including bidirectional footnotes, pagination, a table of contents, etc.; simple, foundational things, really. examples of each of these are included in the book, but not in one place. having such an example in one place would be something that could be used as a quick-start template for us epub beginners. to be fair, code examples of all of this is up on the accompanying website, and i am using these examples as i learn to code epub 3 for my own project. but having a single, relatively comprehensive example as an appendix to the book would be very useful. as i read this book, something kept bothering me. epub2 and epub 3 are so very different, with reading systems designed to render epub 3 documents being fairly rare at this point. so if different versions of the same spec are so different, with no guarantee that a future reading system will be able to read documents adhering to a previous version, then the prospect of reading epub documents into the future is pretty sketchy. are e-books, then, just convenient and cool mechanisms for currently reading longish narrative prose—convenient and cool, but transitory? mark cyzyk is the scholarly communication architect in the sheridan libraries, johns hopkins university, baltimore,

https://doi.org/10.6017/ital.v40i2.13513 i write this column from the vantage point of my current role as a member of the core technology section leadership team, and as a newly elected president-elect of core, with my term starting in july 2021. the planning for core began years ago but became a real division of ala in the most chaotic of times. visions for the first year of core were set aside as we had to face the reality of all the work needing to be done remotely, without any conferences that would allow for in-person conversations, and with all the leadership and members under personal and professional strain. yet being forced to start up slowly and deliberately provides some advantages. settling into this new situation has allowed staff, leaders, and members to acclimate to a new division an d learn how we want to do things in the future, rather than relying too much on how we did things in the past or feeling pressure to meet every demand. right now, we are all at a juncture in our personal and professional lives, and thinking about how to approach the coming months. summer offers the promise of growth and reinvention. the pause that a break implies allows time for us both as individuals to make time for what is important to us, and as members or employees of institutions to reconsider our priorities. for people working in library technology, however, the “summer break” is often anything but. public libraries become a hub for activity as schools are closed, and school and academic libraries may use slow periods when classes are not in session for necessary systems upgrades or to roll out a new service. the summer of 2020 was one of the most challenging of my life, both professionally and personally, and meeting all the demands of the moment left hardly any time for a true break. this year, just like last year, feels like a summer we might not let ourselves rest for a moment. while many libraries have been open to some degree over the past year, the upcoming summer has the potential for a return to something like normal. shutting down regular in-person services and buildings felt chaotic since it required new ways of providing those services and building up new technical infrastructure, but without us having expected this in advance like a normal summer project. the return may also feel chaotic, but rather than approaching it as a series of tasks in a plan that requires lots of energy and work, i hope we can treat the time as a period of reflective practice and give ourselves time to understand what has changed. adapting to the realities of life since spring of 2020 has changed us all in various ways, and so too our library users have new needs and expectations. in some cases, they have embraced new services, though this has not been a smooth process for everyone. i have a family member who started using an e-reader for the first time during the pandemic to access library e-books when her public library was closed or had limited services. she was grateful for the option to access books this way, but occasionally struggled to follow the complex workflow from library app to vendor site to device. without the ability to visit a physical reference desk to ask for help, she asked me to assist with device troubleshooting on several occasions. that worked well for her, but margaret heller (mheller1@luc.edu) is digital services librarian, loyola university chicago, and (as of july 1, 2021) president-elect of the core: leadership, infrastructure, futures division of ala. © 2021. mailto:mheller1@luc.edu information technology and libraries june 2021 making room for change through rest | heller 2 not everyone has a digital services librarian in their quarantine bubble. i share this to illustrate that while some people will have adapted or gotten the help they need, for many, this time has been one of doing without or maladaptation. going back to “normal” will not help those who will need even more than they did pre-pandemic. taking time to understand that fact, and to accept that it will not be a quick process of return for many people, will allow us to give each other space to find a way back to our lives as library users and library employees. while many of us feel uncomfortable when we see slow progress—i know i do—i am coming to realize the value of making space for slowness and for rest. rest comes in all forms. it could be physical rest, but it could be pursuing an artistic or athletic hobby, intentional social interactions, or spiritual practices. institutions might give extra time off or set healthy expectations for work hours and meeting-free days, while also discarding old practices and attitudes to create better future work environments. there are crises to which we must immediately react and respond, but without personal and institutional energy in reserve, we will not do as good a job when they occur. crises include political upheaval, public health emergencies, and other major events, but we can also appreciate how they unfold on a more mundane level. information technology work often requires odd hours, intense bursts of energy to complete projects in a small window of time, and unpredictable problems that require dropping everything else to address an emergency. it is natural to constantly look towards the most urgent and the newest problem. this tendency results in lengthy backlogs for requests and accumulates technical debt from deferred maintenance or refactoring. yet as we bring our libraries and other institutions out of pandemic mode over the next few years, allowing for reflective space can help us to be cautious about the choices we make. for example, during earlier stages of the pandemic, many of us probably had to set u p systems for some type of surveillance to maintain social distancing and aid in contact tracing. taking some time to review all those new procedures and systems—and purposefully dismantle those with negative privacy implications—will help us to go forward as more ethical and empathetic institutions. taking it slow is going to be the only way through the next period. summer 2021 should be about reflection on collective trauma. we responded to the events of the past year, whether it was for closing libraries, keeping libraries open as safely as possible, racial justice work, or election support, and now we must consider how to incorporate what we started into lasting change. to do that reflection will require rest. we know how important rest is but finding space for it is not usually a high priority. rest allows us to integrate our experiences, and will build us back to make sure we can keep responding to what comes next. i am challenging myself to spend time in deliberate reflection at the cost of mindless productivity over the coming months so that i can keep helping my library and core succeed. i hope you will consider doing the same. lita president's message: a framework for member success lita president’s message a framework for member success emily morton-owens information technology and libraries | march 2020 https://doi.org/10.6017/ital.v39i1.12105 emily morton-owens (egmowens.lita@gmail.com) is lita president 2019-20 and the assistant university librarian for digital library development & systems at the university of pennsylvania libraries. this column represents my final venue to reflect on our potential merger with alcts and llama before the vote. after a busy midwinter meeting with lots of intense discussions about the steering committee on organizational effectiveness (scoe)’s recommendations, the divisions, the merger, ala finances, and more, my thoughts keep turning in a particularly wonkish direction: towards our organization. so many of the challenges before us hinge on one particular dilemma. for those of us who are most involved in ala and lita, the organization (our committees, offices, processes, bylaws, etc.) may be familiar and supportive. but for new members looking for a foothold, or library workers who don’t see themselves in our association, our organization may look like a barrier. moreover, many of our financial challenges are connected to our organization. the organization must evolve, but we must achieve this without losing what makes us loyal members. while ala and lita have specific audiences of library workers and technologists, we have a lot in common with other membership organizations. one of the responsibilities for the lita vicepresident is attendance at a workshop put on by the american society of association executives, where we learn how to steward an organization. representatives from many different groups attended this workshop, where i had a chance to discuss challenges with leaders from medical and manufacturing associations, and i learned that these challenges are often orthogonal to the subject matter at hand. everyone was dealing with the need to balance membership cost and value, how to give members a voice while allowing for agile decision-making, and how to put on events that are great for attendees without becoming the only way to get value from membership. hearkening back even further, i worked as a library-school intern at a library with a long run of german and french-language serials that i retrospectively cataloged. one batch that has always stuck in my mind is the planning materials for international congresses that were held in the early 20th century by the international societies for horticulture and botany. these events were massive undertakings held at multi-year intervals, gradually planned by international mail. interested parties would receive a lavish printed prospectus, with registration and travel arrangements starting several years in advance. the most interesting documents pertained to the events planned for the mid to late 1930s in europe. these events were cancelled or fell short of intentions because of pre-world war ii political pressures. the congress schedules did not resume until 1950 or later, with some radical changes—for example, german was no longer used as the language of science, and the geographic distribution of events increased significantly in the later 20th century. when i first encountered this material, i was intrigued by how the war affected science. looking back now, i see a dual case study in organizations weathering a crisis whose magnitude we can only imagine, and then reinventing themselves on the other side. both of these organizations still exist and continue to meet, by the way—and i can’t help but feel that reinvention is the key to survival. mailto:egmowens.lita@gmail.com information technology and libraries march 2020 a framework for member success | morton-owens 2 our organizational framework is a key part of the challenge for both ala and lita. i have no doubt that members remain excited about our key issues for advocacy, our subjects for continuing education, and our opportunities for networking. but we have concerns about how we make those things happen. in lita, for example, continuing education requires a massive effort on the part of both member volunteers and staff to organize. we need to brainstorm relevant topics, recruit qualified instructors, schedule and promote the events, and finally run the sessions, collect feedback, and arrange payment for the instructors. this takes the time of the same people we’d like to have creating newsletters and booking conference speakers. meanwhile, right across the hall at ala headquarters, we have staff from alcts and llama doing the same things. these inefficiencies hit at the heart of our financial problems. at the ala level, scoe has proposed ideas like a single set of dues structures for divisions, and a single set of policies and procedures for all round tables. these changes would reduce the overhead required to operate these groups as unique entities, a financial benefit, while also making it easier for members to afford, join, and move between them, a membership benefit. that framework also offers us an opportunity to improve our associations. members have been asking how the association can act more responsively on issues of diversity, equity, and inclusion—for example, how can we have incident response that is proactive and sensitive to member needs while recognizing the complexities of navigating that space as a member-based organization. this is a chance to live up to our aspirations as a community. the actions lita has taken to extend all forms of participation to members who can only participate remotely/online are a way to make us more accessible to library workers regardless of finances or home circumstances. bylaws and policies may not be the most glamorous part of associations but they are the levers we can employ to change the character of our community. coming back to core, we can observe elements of the plan that are responding to both threats and opportunities. members of alcts, llama, and lita know that financial pressures are a major impetus for the merger effort. but, in the hope of achieving a positive reinvention, the merger planning steering committee put most of its emphasis on the opportunity side. the diagram of intersecting interests for core’s six proposed sections (https://core.ala.org/core-overlap/) is a demonstration of the new frontiers of collaboration that core will offer members. the proposed structure of core retains committees while also offering a more nimble way to instantiate interest groups. moreover, the process of creating core reflects the kind of transparent process we want to see in the future. the steering committee and the communications sub-committee crossed not just the three divisions but also different levels of experience and types of prior participation in the divisions. the communications group answered freeform questions, held twitter ama’s, and held numerous forums to collect ideas and feelings about the project. zoom meetings and twitter are not new media, but the sustained effort that went into soliciting and responding to feedback through these channels is a new mode for our divisions. the lita board recently issued a statement (https://litablog.org/2020/02/news-regarding-thefuture-of-lita-after-the-core-vote/) explaining that if the core vote does not succeed, we don’t see a viable financial path forward and will be spending the latter half of 2020 and the beginning of 2021 working toward an orderly dissolution of lita. it is tempting to approach this crossroads from a place of disappointment or fear. we cannot yet say precisely what it will be like to be a https://core.ala.org/core-overlap/ https://litablog.org/2020/02/news-regarding-the-future-of-lita-after-the-core-vote/

when i look at the organizational structure core offers us, i feel hopeful about it being a framework in which members will find their home and flourish. the new division includes what we need for a rich member experience coupled with a streamlined structure that makes it easier to be involved in the ways and extent that make sense for you. in fifty years, perhaps a future member of core will be writing a letter to their members: looking back at this moment of technological and organizational disruption and reflecting on how we reinvented our organization at the moment it needed it most. 8 information technology and libraries | june 20088 information technology and libraries | september 2008 from our readers: virtues and values in digital library architecture mark cyzyk editor’s note: “from our readers” will be an occasional feature, highlighting ital readers’ letters and commentaries on timely issues. at the fall 2007 coalition for networked information (cni) conference in washington, d.c., i pre-sented “a survey and evaluation of open-source electronic publishing systems.” toward the end of my presentation was a slide enumerating some of the things i had personally learned as a web application architect during my review of the systems under consideration: n platform independence should not be neglected. n one inherits the flaws of external libraries and frameworks. choose with care. n installation procedures must be simple and flawless. n don’t wake the sysadmin with “slap a gui on that xml!”—and push application administration out, as much as possible, to select users. n documentation must be concise, complete, and comprehensive. “i can’t guess what you’re thinking.” initially, these were just notes i thought might be useful to others, figuring it’s typically helpful to share experiences, especially at international conferences. but as i now look at those maxims, it occurs to me that when abstracted further they point in the direction of more general concepts and traits—concepts and traits that accurately describe us and the products of our labor if we are successful, and prescribe to us the concepts and traits we need to understand and adopt if we are not. in short, peering into each maxim, i can begin to make out some of the virtues and values that underlie, or should underlie, the design and architecture of our digital library systems. n freedom and equality platform independence should not be neglected. “even though this application is written in platformindependent php, the documentation says it must be run on either red hat or suse, or maybe it will run on solaris too, but we don’t have any of these here.” while i no doubt will be heartily flamed for suggesting that microsoft has done more to democratize computing than any other single company, i nevertheless feel the need to point out that, for many of us, windows server operating systems and our responsibility for administering them way back when provided the impetus for adding our swipe-card barcodes to the acl of the data center—surely a badge of membership in the club of enterprise it if ever there was one. you may not like the way windows does things. you may not like the way microsoft plays with the other boys. but to act like they don’t exist is nothing more than foolish burying one’s head in the *nix sand. windows servers have proven themselves time and again as being affordable, easily managed, dependable, and, yes, secure workhorses. windows is the ford pickup truck of the server world, and while that pickup will some day inevitably suffer a blowout of its twenty-year-old head gasket (and will therefore be respectfully relegated to that place where all dearly departed trucks go), it’s been a long and good run. we should recognize and appreciate this. windows clearly has a place in the data center, sitting quietly humming alongside its unix and linux brothers. i imagine that it actually takes some effort to produce platform-dependent applications using platform-independent languages and frameworks. such effort should be put toward other things. keep it pure. and by that i mean, keep it platform independent. freedom to choose and presumed equality among the server-side oses should reign. n responsibility and good sense one inherits the flaws of external libraries and frameworks. choose with care. so you’ve installed the os, you’ve installed and configured the specified web server, you’ve installed and configured the application platform, you’ve downloaded and compiled the source, yet there remains a long list of external libraries to install and configure. one by one you install them. suddenly, when you get to library number 16 you hit a snag. it won’t install. it requires a previous version of library number 7, and multiple versions of library number 7 can’t be installed at the same time on the same box. worse yet, as you take a break to read some more of the documentation, it sure looks like required library number 19 is dependent on the current version of library number 7 and won’t work with any previous version. and could it be that library number 21 is dependent on library number 20, which is dependent on library number 23, which is dependent on—yikes—library number 21? mark cyzyk (mcyzyk@jhu.edu) is the scholarly communication architect, library digital programs group, sheridan libraries, johns hopkins university in baltimore. from our readers: virtues and values in digital library architecture | cyzyk 9 all things come full circle. but let’s suppose you’ve worked out all of these dependencies, you’ve figured out the single, secret order in which they must install, you’ve done it, and it looks like it’s working! yet, when you go to boot up the web service, suddenly there are errors all over the place, a fearsome crashing and burning that makes you want to go home and take a nap. something in your configuration is wrong? something in the way your configuration is interacting with an external library is wrong? you search the logs. you gather the relevant messages. they don’t make a lot of sense. now what to do? you search the lists, you search the wikis to no avail, and finally, in desperation, you e-mail the developers. “but that’s a problem with library x, not with our application.” au contraire. i would like to strongly suggest a copernican revolution in how we think about such situations. while it’s obvious that the developers of the libraries themselves are responsible for developing and maintaining them, i’d like to suggest that this does not relieve you, the developer of a system that relies on their software, from responsibility for its bugs and peculiar configuration problems. i’d like to suggest that, far from pushing responsibility in the case mentioned above out to the developers of the malfunctioning external library, that you, in choosing that library in the first place, have now inherited responsibility for it. even if you don’t believe in this notion of inheritance, if you would please at least act as if it were true, we’d all be in a better place. part of accepting this kind of responsibility is you then acting as a conduit through which we poor implementers learn the true nature of the problem and any solutions or temporary workarounds we may apply so that we can get your system up and running pronto. in the end, it’s all about your system. your system as a whole is only as strong as the weakest link in its chain of dependencies. n simplicity and perfection installation procedures must be simple and flawless. it goes without saying that if we can’t install your system we a fortiori can’t adopt it for use in our organization. i remember once having such a difficult time trying to get a system up and running that i almost gave up. i tried first to get it running against apache 1.4, then against apache 2.0. i had multiple interactions with the developers. i banged my head against the wall of that system for days in frustration. the documentation was of little help. it seemed to be more part of an internal documentation project, a way for the developers to communicate among themselves, than to inform outsiders like me about their system. and related to this i remember driving to work during this time listening to a report on npr about the famous hopkins pediatric neurosurgeon, dr. ben carson. apparently, earlier in the week he had separated the brains of siamese twins and the twins were now doing fine, recuperating. the npr commentator marveled at the intricacy of the operation and at the fact that the whole thing took, i believe, five hours. “five hours? five hours?!” i exclaimed while barreling down the highway in my vintage 1988 ford ranger pickup (head gasket mostly sealed tight, no compression leakage). “i can’t get this system at work installed in five days!” our goal as system architects needs to be that we provide to our users simple and flawless installation procedures so that our systems can, on average, be installed and configured in equal or less time than it takes to perform major brain surgery.1 “all in an afternoon” should become our motto. i am happy to find that there are useful and easy to use package managers, e.g., yum and synaptic, for doing such things on various linux distributions. windows has long had solid and sophisticated installation utilities. tomcat supports drop-in-place war files. when possible and appropriate, we need to use them. n justice and e-z livin don’t wake the sysadmin with “slap a gui on that xml!”—and push application administration out, as much as possible, to select users. i remember reading plato’s republic as an undergraduate and the feeling of being let down when the climax of the whole thing was a definition in which “justice” simply is each man serving his proper place in society and not transgressing the boundaries of his role. “that’s it?” i thought. “so you have this rigidly hierarchical society and each person in it knows his role and knows in which slot his role fits—and keeping to this is ‘justice’?” this may not be such a great way to structure a society, but now that i think about it, it’s a great way to structure a computer application. sit down and carefully look at the functions your program will provide. then create a small set of user roles to which these functions will be carefully mapped. in the end you will have a hierarchical structure of roles and functions that should look perfectly simple and rational when drawn on a piece of paper. and while the superuser role should have power over 10 information technology and libraries | september 2008 all and access to all functions in the application, the list of functions that he alone has access to should be small, i.e., the actual work of the superuser should be minimized as much as possible by making sure that most functions are delegated to the members of other, appropriate, proper user roles. doing this happily results in what i call the state of e-z livin: the last thing you want is for users to constantly be calling you with data issues to fix. you therefore will model management of the data—all of it—and the configuration of the application itself—most of it— directly into the architecture of the application, provide users the guis they need to configure and manage things themselves, and push as much functionality as you can out to them where it belongs. let them click their respective ways to happiness and computing goodness. you build the tool, they use it, and you retire back to the land of e-z livin. users are assigned to their roles, and all roles are in their proper places. application architecture justice is achieved. n clarity and wholeness documentation must be concise, complete, and comprehensive. “i can’t guess what you’re thinking.” as system developers we’ve probably all had the magical experience of a mind meld with a fellow developer when working intensively on a project. i have had this experience with two other developers, separately, at different stages of my career. (one of them, in fact, used to point out to everyone that, “between the two of us, we make one good developer!”) this is a wonderful and magical and productive working relationship in which to be, and it needs to be recognized, supported, and exploited whenever it happens. you are lucky if you find yourself designing and developing a system and your counterpart is reading your mind and finishing your sentences. however, just as it’s best to leave that nice young couple cuddling in the corner booth alone, so too it really doesn’t make a lot of sense to expect the mind-melded developers to turn out anything that remotely resembles coherent and understandable documentation. those undergoing a mind meld by definition know perfectly well what they mean. to the rest of us it just feels like we missed a memo. if you have the luxury, make sure that the one writing the documentation is not currently undergoing a mind meld with anyone else on the development team. scotty typically stayed behind while he beamed the others down. beam them down. be that scotty. you do the world a great service by staying behind on the ship and dutifully reporting, clearly and comprehensively, what’s happening down on the red planet. to these five maxims, and their corresponding virtues, i would add one more set, one upon which the others rely: n empathy and graciousness you are not your audience. at least in applied computing fields like ours, we need to break with the long-held “guru in the basement” mentality. the actions of various managerial strata have now ostensibly acknowledged for us that technical expertise, especially in applied fields, is a commodity, i.e., it can be bought. a dearth of such expertise is remedied by simply applying money to the situation—admittedly difficult to do at the majority of institutions of higher education, but a common occurrence at the wealthiest. nevertheless, the dogmatic hold of the guru has been broken and the magical aura that once draped her is not now so resplendent—her relative rarity, and the clubby superiority that depended upon it, has been diluted significantly by the sheer number of counterparts who can and will gleefully fill her function. we respect, value, and admire her; it’s just that her stranglehold on things has (rightfully) been broken. and while nobody is truly indispensable, what is more difficult and rare to find is someone who has the guru’s same level of technical chops coupled with a genuine empathic ability to relate to those who are the intended users of her systems and services. unless your systems and services are geared primarily toward other developers, programmers, and architects— and presumably they are not, nor, in the library world, should they be—your users will typically be significantly unlike you. let me repeat that: your users are not like you. rephrased: you are not your audience. when looking back over the other maxims, values, and virtues mentioned in this essay then, the moralpsychological glue that binds them all is composed of empathy for our users—faculty, students, librarians, non-technical staff—and the graciousness to design and carry out a project plan in a spirit of openness, caring, flexibility, humility, respect, and collaboration. when empathy for the users of our systems is absent—and there are cases where you can actually see this in the design and documentation of the system itself—our systems will ultimately not be used. when the spirit of graciousness is broken, men become robots, mere rule followers, and users will boycott using their systems and will look elsefrom our readers: virtues and values in digital library architecture | cyzyk 11 where, naturally preferring to avoid playing the simonsays games so often demanded by tech folk in their workaday worlds; there is a reason the comic strip dilbert is so funny and rings so true. when confronted with a lack of empathy and graciousness on our part, the users who can boycott using our systems and services will boycott using our systems and services. and we’ll be left out in the rain, feeling like, as bonnie raitt once sadly sang, “i can’t make you love me if you don’t / i can’t make your heart feel something it won’t.” empathy and graciousness, while not guaranteeing enthusiastic adoption of our systems and services, are a necessary precondition for users even countenancing participation. there are undoubtedly other virtues and values that can usefully be expounded in the context of digital library architecture—consistency, coherence, and elegance immediately come to mind—and i could go on and on analyzing the various maxims surrounding these that bubble up through the stack of consciousness during the course of the day. yet doing so would conflict with another virtue i think is key to the success and enjoyment of opinionpiece essays like this and maybe even of other sorts of publications and presentations: brevity. note 1. a colleague of mine has since informed me that carson’s operation took twenty-five hours, not five. nevertheless, my admonition here still holds. when installation and configuration of our systems are taking longer, significantly longer, than it takes to perform major brain surgery, surely there is something amiss? lib-mocs-kmc364-20131012120558 314 news and announcements first use of catvlib network: american red cross satellite telecast on may 21, 1981, the american red cross celebrated their one-hundredth birthday by ending their annual conference in washington, d.c., with a special twohour nationwide satellite telecast. the pssc coordinated distribution of the telecast, which originated from constitution hall in washington, d.c. , from 10 a.m. to noon. the program was carried on satcom i, transponder 16 (appalachian community service network), and made available to all cable systems able to receive this transponder. those areas not able to schedule the live program were offered a satellite-transmitted taped feed later in the day. the american red cross had encouraged all its local chapters to initiate program reception in their communities by approaching the local cable system about carrying the event. since the american red cross was offering a free program and trying to saturate as much of the united states as possible, use of the catvlib network in conjunction with this telecast was appropriate. pssc contacted 53 libraries in 23 states that were interested in assuming local coordination for bringing this event to their communities. as the local coordinator, the ca tvlibs' minimum responsibilities included alerting the cable systems to schedule receiving this program (if the local red cross chapter had not already approached the catv) and contacting the local red cross chapter to offer the catvlibs' facilities for their group viewing and concomitant local celebration. of these fifty-three catvlibs , only seven could not participate because of technical problems. schedule conflicts; lack of catv, red cross, or community interest; and red cross alternative plans were the major factors in prohibiting twelve others from directly participating in hosting the satellite-transmitted program. the remaining thirty-four catvlibs did host community residents in their facilities. evaluation forms revealed a variety of degrees of catvlib participation in coordinating their first satellite event participation. several catvlibs (though none came to the library for viewing) were instrumental in getting the program into the community and available to all local cable subscribers. advance publicity, birthday cakes and refreshments, sing-alongs, taping for multiple showings, and joint library/ chapter preand postevent activities are but a few of the ways the individual catvlibs participated. all of the evaluation forms indicated that the ca tvlibs wanted to be contacted as a potential local site for future satellite events. the following list names the fifty-t hree ca tvlibs that were initially contacted to be local coordinators for the red cross onehundredth birthday satellite telecast. though not all were successful, catvlib made an effort to bring the program to its community. colorado boulder public library, boulder connecticut thomaston public library, thomaston florida tarpon springs public library, tarpon springs georgia tri-county

arrives the "new arrival" to the library association family this summer is the electronic library membership initiative group. elmig is an organization of individuals established to ensure that electronically delivered information remains accessible to the general public. elmig promotes participation and leadership in the remote electronic delivery of information by publicly supported libraries and nonprofit organizations. the group's efforts are coordinated by richard sweeney, director of the public library of columbus and franklin county; neal kaske, director of oclc's office of research; and kenneth dow lin, director of the pikes peak library district. the first founding goals of elmig are: • identifying services and information best suited for the remote electronic access to and delivery of information; • planning, funding, and developing working demonstrations of library electronic information services; • communicating the availability of electronic library services to the community; • informing the library profession of trends, specific events, and future directions in remote electronic delivery of information; • creating coalitions with organizations in allied fields of interest. organizers of elmig are working within ala to foster interest in , and facilitate the needs of, the electronic library. ala has established a membership initiative group to address the concerns of this group. the electronic library membership initiative group will meet during the ala midwinter meeting in denver. interested individuals are encouraged to attend the meeting scheduled for monday, january 25, 1982, at 2 p.m. in room 2e of the auditorium. interest in elmig/ela has surfaced quickly. the membership group was formed in march, and gathered the 200 signatures needed for official recognition at the ala annual conference in san francisco. some 150 people met at that conference to discuss topics of concern. they decided to continue these discussions at the 1982 midwinter meeting and plan for an elmig program to be presented at philadelphia. elmig aims to address the issues concerning the electronic library on a continuing basis through ongoing interaction of its members. to facilitate this interaction, elmig will use an electronic mail system. further information on elmig and its members is available from richard sweeney at the public library of columbus and franklin county, 28 s. hamilton rd., columbus, oh 43213. see page 317 for subscriber agreement form. heynen to head arl microform project the association of research libraries has hired jeffrey heynen to head a two-year program designed to improve bibliographic access to microform collections in american and canadian libraries. the association has received $20,000 from the council on library resources to initiate the project, and additional funds are anticipated from other sources. heynen brings an extensive background in micrographics and publishing to the project as well as a long-standing commitment to improving the treatment , use, and bibliographic control of microforms in libraries. he has served as chair of the american library association's reproduction of library materials section, and was a participant in earlier groups that laid the foundation for the current arl project. currently president of information interchange corporation, heynen has held executive positions with congressional information service, greenwood press, and redgrave information resources. these positions have all included responsibility for the creation of large microform collections. heynen hold~ memberships in numerous standards-making bodies, including the international organization for standardization (iso), the american national standards institute, and the national micrographics association, and is a lecturer at the university of maryland college of library and information services. the arl microform project is based upon a planning study conducted for the association by richard boss of information systems consultants, inc. its purpose is to stimulate and coordinate the work of libraries, microform publishers, bibliographic utilities, and regional networks in providing bibliographic access to millions of monographic titles in microform that are now inadequately or insufficiently cataloged. since the development of the plan during 1980, there has been keen interest both in the elements of the plan and in the cooperative efforts needed to achieve them. a number of libraries-both arl and nonarl members-are planning to begin or are already entering catalog records for individual titles in microform sets into bibliographic databases. for example, three arl libraries have recently been awarded grants under title 11-c of the higher education news and announcements 317 act, strengthening research library resources, to catalog major microform sets, entering the resulting records into one of the major utilities. all three librariesstanford university, university of utah, and indiana university-will be coordinating their efforts with the goals of the arl program. key to these efforts, however, is coordination to ensure that national standards are accepted and followed, to distribute the work load so that as many sets as possible are covered and duplication of effort is avoided, and to ensure that the records are available to all libraries that want to use them. the arl microform project will emphasize building on existing resources, coordinating efforts among the library and pubsubscriber agreement electronic

of the new jersey digital highway (njdh, www.njdigitalhigh way.org) and its portal structure. the njdh intends to provide an immersive and user-centered portal for new jersey history and culture. the research recruited 145 participants and used a web-based questionnaire that contained three sections: for everyone, for educators, and for curators. the feedback on the usefulness of the njdh was positive and the portal structure was favorable. the research uncovered several reasons why some collections did not want to or could not participate. the findings also suggested priorities for further development. this study is one of the few on the evaluation of cultural heritage digital library. t he new jersey digital highway (njdh, www .njdigitalhighway.org) is a digital library for new jersey history and culture, including collections of new jersey libraries, museums, archives, and historical societies. the njdh, funded in part by the 2003 national leadership grant of the institute for museum and library services, is a joint project by new jersey state library, the new jersey division of archives and records management at rutgers university libraries, the new jersey historical society, and the american labor museum. as part of the project, the njdh identifies 686 cultural heritage institutions (public libraries, archives, historical societies, and museums). as of november 2007, there are more than ten thousand objects (pictures, records, and oral histories) in the repository. more are being added daily. the njdh, at this writing, is still very much a work in process. the principal investigator of this project continues to extend opportunities to more communities to link their sites and scan their images.1 the njdh provides portals for four different groups of people: everyone, educators, students, and librarians and curators. its mission is to develop an immersive, user-centered information portal and to support the new jersey learner through a collaboration among cultural heritage institutions that supports preservation of the past, new access strategies for the future, and active engagement with resources at the local and the global level for shared access and local ownership. the njdh uses fedora (flexible extensible digital object repository architecture) as a platform to mount participating institutions’ digital objects and metadata. fedora is developed jointly by cornell university and the university of virginia and is currently supported through an andrew w. mellon foundation grant that is customizable and allows local institutions to have true control over what they digitize and post.2 fedora is built on xml with core standards that support flexibility and interoperability such as mets (metadata encoding and transmition standard, www.loc.gov/standards/ mets) and oai-pmh (open archives initiative protocol for metadata harvesting, www.openarchives.org) functions. fedora is chosen for the njdh because it can effectively accommodate and manage a broad array of information sources with the flexibility to integrate with other information repositories. the njdh uses a metadata structure based on mods (metadata open description schema, www.loc.gov/ standards/mods), mets, niso, and premis (preservation metadata, www.loc.gov/standards/premis) metadata standards to support preservation of digital objects, to ensure scalability for projects and interoperability with other systems through oai-pmh. this hybrid approach enables njdh collection managers and metadata creators to provide information through multiple presentation standards in a schema easily understood within distinctive cultural heritage organization communities. mods is used for descriptive metadata, provides and retains standard bibliographic cataloging principles, and is therefore easily mapped to marc. the njdh therefore includes a mapping utility that allows the export of records from the njdh to online catalogs for any organization that wants to make its digital objects accessible within its integrated library system. additionally, there are four other types of metadata in njdh: source metadata describes provenance, condition, and conservation of analog source materials such as photographs, books, maps, audio, and video; technical metadata describes born digital images and provides information about the digital master files that will be maintained for long-term preservation and access; rights metadata identifies the rights holder(s) for each information source, identifies the permissions for use including any restrictions, and documents the copyright status of each work; digital provenance metadata provides a digital “audit trail” of any changes to the metadata.3 the use of the njdh has steadily grown and has some three thousand unique visitors a month averaging eight to ten thousand visits per month.4 n prior cultural heritage digital library evaluations literature review indicates that few researchers have investigated the usability or the evaluation of cultural judy jeng (jjeng@njcu.edu) is head of collection services, new jersey city university, new jersey. 18 information technology and libraries | december 2008 heritage digital libraries. the minerva (ministerial network for valorising activities) project proposed a number of criteria and principles specifically for usability evaluations of cultural web applications, including visibility, affordance, natural mapping, constraints, conceptual models, feedback, safety, flexibility, the scope and aim of the site, meaningful organization of the website’s functions, quality of content (for example, consistency, completeness, conciseness, accuracy, objectivity), design of functional layout, consistent use of graphics and multimedia components, as well as provision for navigation tools and search mechanisms.5 in addition, vaki, dallas, and dalla proposed sixteen usability guidelines for cultural applications.6 garoufallou, siatri, and balatsoukas reported their research on the user interface of the veriagrid application.7 the veriagrid system (www.theveriagrid.org) is a platform based on digital cartography that supports a vector map of the city of veria organized by layers and linked to multimedia objects such as text, images, photos, and video clips. the researchers were interested in learnability, errors, and satisfaction. n usefulness as the primary evaluation criterion for the njdh the njdh aims to serve heterogeneous communities and information needs. like other digital cultural services, it is not easy to address usability issues. lynch has said that digital libraries of cultural heritage don’t really have natural communities around them and that digital materials find their own unexpected user communities.8 garoufallou, siatri, and balatsoukas said that “different types of users, such as students and scholars or tourists and travelers look at these services from different angles (for example, scholarly or recreational needs). thus, the provision of accessible and user-friendly systems is important for the wider use and acceptance of these services.”9 the aim of this evaluation was to assess usefulness of the njdh from the perspectives of general users, educators, and cultural heritage professionals. usefulness is one of the criteria of usability with a focus on “did it really help me?” and “was it worth the effort?” usefulness differs from usableness in that usableness refers to functions such as “can i turn it on?” or “can i invoke that function?” usefulness can also mean “serving an intended purpose.” in the technology acceptance model (tam) developed by davis and his colleagues, perceived usefulness refers to the extent to which an information system will enhance a user’s performance.10 in addition to usefulness and usableness, jeng has gathered a comprehensive collection of usability criteria such as effectiveness, efficiency, satisfaction, learnability, ease of use, memorability, mistake recovery, and interface effectiveness.11 usability is a multidimensional construct and has a theoretical root in human–computer interaction. although usefulness may be an important evaluation criterion, thomas and jeng report that usefulness is an often overlooked criterion of usability.12 literature review indicates that usefulness has been used as either the primary or one of the criteria in the following evaluations of digital libraries: elibraryhub, the digital work environment, grow (geotechnical, rock, and water engineering, www.grow.arizona.edu), mcmaster university library’s gateway, the miguel de cervantes virtual library, minnesota’s foundations project, and the moving image collections.13 this paper reports the evaluation of the njdh. n research method a web-based online survey was conducted in september– december 2006. the questionnaire was designed, collected, and analyzed using web-based software called surveymonkey. convenience sampling method was used in this study. subjects were recruited by posting a link on the njdh website, by posting announcements on a number of electronic discussion lists for educators and cultural heritage professionals, and by word-of-mouth invitations. the participants were asked to complete a two-part questionnaire. the first part gathered demographic data such as gender, age, ethnic background, educational background, the county they live in, and how they learned about the njdh. the second part contained three sections: one for everyone, one for educators, and one for cultural heritage professionals. the section for everyone contained twenty-six questions, including seven-point likert scales and open-ended questions with a focus on the digital library’s usefulness, navigation, design, terminology, and user lostness. in addition to this general section, educators were asked to complete another fifteen questions pertaining specifically to the educators’ portal; the cultural heritage professionals had another thirteen questions regarding the librarians and curators’ portal. a total of 145 individuals participated in the survey, of which 32 were educators (22%) and 28 (20%) were cultural heritage professionals. the participants were mostly white (127 respondents or 89%), mostly female (118 respondents or 81%), and most had a master’s or doctoral degree (114 respondents or 79%). in terms of age distribution, more than half of the participants were over 50 (79 respondents or 55%) (see table 1). nearly all (136 respondents or 94%) were residents of new jersey. evaluation of the new jersey digital highway | jeng 19 among the educators that participated in this survey who evaluated the educators’ portal, 56% (18 respondents) worked at colleges or universities, 16% (5 respondents) worked at high schools, 13% (4 respondents) worked at elementary or middle schools, and 6% (2 respondents) identified themselves as specialists in museums, libraries, or archives. roughly a third (10 respondents or 31%) were teachers, 3% (1 respondent) was a teaching assistant, 13% (4 respondents) were school administrators, and 28% (9 respondents) were school library media specialists or librarians (see table 2). in terms of what they teach, 27% (7 respondents) teach new jersey history, 23% (6 respondents) teach social studies, 12% (3 respondents) teach civics, 8% (2 respondents) teach geography, and 8% (2 respondents) teach popular culture. as to the survey participants who identified themselves as cultural heritage professionals, 61% (17 respondents) worked at libraries, 11% (3 respondents) worked at museums, 11% (3 respondents) worked at historical societies, and 4% (1 respondent) worked with archives. in terms of their roles at those organizations, 61% (17 respondents) said they were faculty or staff, 18% (5 respondents) were administrators, one was a consultant, one was a librarian, and one was a volunteer (see table 3). n findings how do users find out about the njdh and will they come back? the survey found that more than half of the respondents (58 participants or 40%) learned about the njdh from their colleagues or friends, 19 participants (13%) learned through attending conferences, 16 participants (11%) were linked from other websites (see figure 1). the njdh digital library intends to build rich and “one stop shop” digital collections of new jersey history and culture. cultural heritage digital library plays a particularly important role for students of the humanities because the digital library is the humanist’s laboratory, its resources are the scholar’s primary data.14 it is important to enhance users’ awareness of this digital library among new jerseyans and even promote this cultural heritage digital library to users at global level. table 1. demographic data (n = 145) total % gender male 27 18.6 female 118 81.4

degree 7 4.8 bachelor’s degree 19 13.1 master’s or phd degree 114 78.6 in terms of the purposes of visiting the njdh, the study found 72 respondents (76%) were just browsing and 23 respondents (24%) were looking for specific information such as a specific county information, history, and family genealogy (see figure 2). seventy-two respondents (74%) replied that they will come back to use the njdh again (see figure 3). those who said “no” gave reasons such as their doubts on whether the information in the njdh is reliable and authoritative, the depth and breadth of content in this digital library, and the inconsistency of fonts and font sizes. n navigation navigation has been reported in literature as a common problem in a digital library. users could accidentally leave the digital library, following the links to other web-based resources, and were unaware that they were no longer using the digital library. brinck, gergle, and wood report that disorientation is among the biggest frustrations for web users.15 20 information technology and libraries | december 2008 average 2.54 on a 7-point likert scale, 1 being easy to navigate and 7 being difficult to navigate). twentythree participants (25%) marked 1 on the likert scale, 28 participants (30%) marked 2, and 26 participants (28%) marked 3. these brought the total of the top three points to 83%. the overall response regarding user lostness was also not a problem (response average 2.42 on a 7-point likert scale, 1 being not lost at all and 7 being very lost). only two participants expressed they were very lost and one expressed lost. the reasons that could lead to user lostness include the lack of material in the collections so far, the need for explanation of how relevance is ranked, the home page being text heavy and cluttered, the photos not being legible, the lack of author information in documents, no indication of a trail of how one got there, lengthy urls, the need for better chosen direct links instead of layered links, and patrons’ unfamiliarity with icons and their functions. n layout the rating for the layout of the njdh was very positive (response average 2.54 on a 7-point likert scale, 1 being good and 7 being bad). however, the site may improve its appearance in the following areas: there is currently too much text per page (the font is too small and the use of typography, informational hierarchy, and white space must be improved); more important information needs to go at the top of pages; and more colors need to be used. n terminology the degree to which users interact with a digital library depends on how well users understand the terminology displayed on the system interface. literature review has indicated that the inappropriate use of jargon has been a common problem in digital library design. hartson, shivakumar, and pérez-quinones report from their usability inspection of the networked computer science technical reference library (www.ncstrol.org) that problems with wording accounted for 36% of the digital library’s usability problems.16 system designers often assume too much about the extent of user knowledge. the precise use of words in a user interface is one of the utmost important design considerations for usability. table 2. educators’ demographic data (n = 32) total % institutions university or college 18 56 high school 5 16

new jersey digital highway | jeng 21 this research found that the overall response regarding terminology and labeling in the njdh was positive (response average 2.34 on a 7-point likert scale, 1 being clear and 7 being not clear). n usefulness usefulness was the fundamental research focus of this study. this research investigated whether the njdh was useful to the general public, educators, and students. the responses were overwhelmingly positive: 73% of the respondents gave 1–3 ratings on the 7-point likert scale (1 being useful and 7 being not useful)—30% (29 respondents) marked 1, 33% (32 respondents) marked 2, and 12% (12 respondents) marked 3. the average response was 2.63. this was a very positive response. when it comes to the specific section for educators to evaluate the educator’s portal, the rating was also positive (response average 3.04). those educators felt that the most useful information was the “how to” information for teaching with digital resources, research genealogy, developing an oral history, and so on. twelve respondents (44%) indicated they would encourage their students to use the njdh site for term papers or homework assignments. thirteen respondents (50%) indicated they would make their own lesson plans using the resources and information from the njdh. regarding the student’s portal, those educators who responded to the survey indicated that, from their perspectives, the most useful information for students was the general information about new jersey, including a directory of cultural heritage organizations, places to visit, etc. as for the librarians and curators’ portal, those cultural heritage professionals identified the librarians and curators’ resource center as the most useful resource in the njdh, followed by the digital highway collections roadmap and associated guidelines, calendar, the searching capabilities of new jersey cultural heritage organizations, and new jersey information. sixteen respondents (67%) said they would recommend this digital library to their patrons, two respondents (8%) won’t, and six respondents (25%) were not sure. it is obvious that the njdh administrators need to work harder in this area to enhance usefulness for cultural heritage professionals and their patrons. figure 1. where did you hear about njdh? the survey asked all respondents to suggest what themes should be enriched in the njdh collections. the suggestions were, in this order: new jersey history, new jersey state and county documents, new jersey culture, genealogy, everyday life in new jersey, new jersey industry, more immigration resources, education in new jersey, new jersey in wartime, and transportation. regarding the librarians and curators’ portal, the respondents suggested the contents of this particular portal should be enhanced in the following priority order: (1) more links to other websites with history resources and activities, (2) access to mentors experienced in digitizing and metadata who can provide one-to-one assistance, (3) a discussion list or blog where users can ask questions or share ideas with others, (4) information about training sessions around new jersey on digitization and metadata, (5) more resources on digital preservation and metadata, (6) educational activities that users can share with their patrons, (7) a tool for users to create their own interactive activities using the njdh resources, and (8) more information about helping patrons to use the njdh more effectively. n portal structure the njdh provides four portals for different target users: everyone, educators, students, and librarians and curators. each portal provides different interface and packages different information for a different type of user. the survey found 80% of the subjects understood the purpose of the four portals (by marking 1 or 2 on the 7-point likert scale) and only 4 participants (4%) found this type of portal structure confusing. the survey further found 65% of participants felt this kind of portal structure helpful to them. 22 information technology and libraries | december 2008 n why not contributing to the njdh collections? the respondents indicated that the barriers for them to contribute collections or resources to the njdh were, in this order: (1) lack of staff or time, (2) lack of funding, (3) lack of knowledge, and (4) copyright concerns. n statistical analyses the study found demographic factors, such as age, gender, ethnic background, and educational level, do not have significant effects on a number of areas: (1) how the participants ranked usefulness of the digital library, (2) usefulness evaluation of the four-portal structure, (3) understanding of terminology, (4) ease of navigation, and (5) lostness. the study found the correlation between navigation and lostness was statistically significant: r (66) = .83, p < .001. when a user felt the system easy to navigate, the user felt less lost. the study also found usefulness of the digital library has a statistically significant effect on a user ’s return decision. a one-way analysis of variance was conducted. the analysis of variance was significant, f (2, 59) = 20.42, p < .001. the strength of relationship between usefulness ranking and the decision of whether to revisit the digital library, as assessed by n2, was strong, with the usefulness factor accounting for 41% of the variance of the return decision. because the overall f test was significant, follow-up tests were conducted to evaluate pairwise differences among the means. using the turkey test, the pairwise comparisons yes vs. no and yes vs. not sure were significant. the pairwise comparison no vs. not sure was not significant. n conclusions usability evaluation is a user-centered evaluation to learn from users’ needs, expectations, and satisfaction. this research studied usefulness, navigation, user lostness, terminology, and layout. the overall response was positive, and the finding was that the njdh was useful in providing new jersey history and culture information. designers of the njdh learned from the study the priorities of adding various new jersey themes to the collections and how to make the site easier to use. as a result of the study, lifelong learners are identified as an important target audience. this research provided insights on why people came to use this particular digital library, their pleasure of using it, how to improve ease-of-use, navigation, website appearance, and the use of terminology and labeling. the front page of the website was redesigned to address the overuse of text on each page. the study also helped to discover what components of the site were more useful and why. furthermore, it investigated why some museums or collections in new jersey have not participated in this digital library development project. as a result of the study, more emphasis has been placed on building tools figure 2. purpose of the most recent visit figure 3. will you use njdh again? evaluation of the new jersey digital highway | jeng 23 to increase independent collection contribution by museums and archives. the observations of this study may help the development of other academic digital libraries because the barriers found in the study are common obstacles. after eighteen months of the study, the njdh governance planning committee still uses the evaluation report to address more complex and fundamental changes and the reorganization of the digital library. the study confirmed that users of this digital library appreciated the idea of providing different portals for different users. the study did not find demographic factors (age, gender, ethnic background, and educational level) play statistically significant roles in the usefulness rankings of the digital library or portal structure, terminology, ease of use, or user lostness. the study found there was a strong correlation between ease of navigation and user lostness. users don’t have feelings of lostness when a system is easy to navigate. the study also found users will come back to revisit a digital library when they find the site is useful. n acknowledgments judy jeng and grace agnew were the codesigners of the questionnaire for this study. judy served as the evaluation consultant for the njdh. grace agnew, the associate

frederick g. kilgour who, with the able assistance of his assistant editor, eleanor m. kilgour, so firmly established this periodical and set its standards so high. especially in view of the fact that in these first years of journal publication, mr. kilgour was also designing and implementing the complex system which is the ohio college library center, his achievement as first editor was remarkable. to him the information science and automation division of the american library association owes a great debt. as library automation moves further into the seventies, the context of its existence changes. ever-increasing fisca l pressures have required economic justification for every alteration of traditional practice. the mere availability of equipment, of programs and tested system design, even of skilled and experienced manpower can no longer be considered enough. novelty, the magic word "innovation," seldom now cast a spell on those who control institutional budgets. increasingly, in the issues of this journal, we hope that emphasis will be placed on reviews of experience, retrospective evaluations of operation rather than optimistic projections made in the first bright mornings of system design. we must have reports if not of failures at least of alterations and accommodations enforced on operational systems by experience and the heavy hand of time. it is our further hope that the ] ournal will receive more reports from public and school libraries which indicate an increasing dedication, in automation explications, to the social and educational goals of those institutions. -ajg 295 listings of uncataloged collections fred l. bellomy: head, and lies n. jaccarino: systems analyst, library systems staff, university of california, santa barbara, california. an operational computerized system used by the ucsb libraries produces listings of bibliographic data about items in collections where full cataloging treatment is not considered justified. the system produces listings of the brief bibliographic records sorted by any of the data elements in the record including up to twenty-five subjects terrrl8. of special interest are the authority listings of descriptions and the coordinate indexes to the full records. introduction this short report was extracted from the more comprehensive document, listings of uncataloged collectionssystems documentation, santa barbara: university of california, december 1969, library systems document ls 69-11. the library staff at the university of california at santa barbara is using computerized procedures to produce a variety of listings of bibliographic information about items in uncataloged collections. although many similar systems undoubtedly have been developed to do similar jobs, this one is noteworthy in two respects, first in being well-documented and second because its versatility has been tested on three totally different collections. the machine programs, written in pl/1, were first used to list the ucsb art exhibition catalogs collection, but they were designed to be versatile so that they could he applied easily to other similar collections 296 journal of library automation vol. 3/4 december, 1970 as well. at present these programs are also being used at ucsb to list the documentation of marine pollution due to major oil spills (the oil spill information center). the programs have been successfully tested also on about one hundred items of the ucsb collection of early american trade catalogs. application to other collections (such as the phono record collection or video tape file) has been studied and is feasible. although it is usually difficult to use programs that were not specifically tailored for a particular user, these programs represent at least one instance where attention to versatility and the probable broad scope of possible applications has resulted in a system capable of producing listings for different collections at any location where there is access to an ibm system 360 computer and a staff capable of adapting about a half dozen job control language ( jcl) statements. the machine written listings of catalogs provide a limited amount of bibliographic data about each item in the collection. the advantage of such listings is the expedition with which a new, not-yet-cataloged, collection can be made accessible. description as a first step in obtaining a listing, library staff members examine ea~h item in the collection to be listed and transcribe the necessary bibliographic data to an input work sheet (figure 1). information on the work sheet is keypunched into one or more punched cards. these records, once in the computer, can be sorted in various ways to provide a variety of listings. master listings can be produced at desired intervals (e.g. monthly). multiple copies of each list can be produced, and the sheets of computer printout are a convenient form of access to the material when individual copies of the list are separated and placed in hard-board binders for distribution to the library service desks. program "packages" (i.e. jcl decks) contain many comment cards, so that each package is self explanatory after very little instruction. to keep the system simple for the librarians who use it, separate "packages" have been prepared for each different listing (or combination of listings) decided on. listings of the full records (see figure 2) have been prepared now by 1) classification letter, 2) accession number, 3) year of "exhibit", 11) mai~ and secondary subjects, 12) agency name, 13) agency city, and 17) author. obviously, others are possible. listings of subjects (figure 3) and agencies with the number of times each was used accompany full record listings by subject and agency. these are used as authority lists for future term assignments. another package, artindx, is used to produce coordinate indexes by subject, agency, author and others. an example of the subject index is shown in figure 4. such indexes are used with a master listing of the full bibliographic records in accession number order. this method reduces the amount of printout required to provide many different description approaches to the collection. listings of uncataloged collectionsfbellomy and jaccarino 297 catalog collections input worksheet column 1. classification

301 computer program the computer program for the listings consists of several separate job steps. the job step, artread, which reads the data cards into the machine, prepares a file in correct form for the sorting and printing steps. artread will also prepare the master file on disk for fmther processing. the second step, sortd, is a standard utility program in the ibm computer library. it sorts records according to specifications on one of the cards in the program package. the third job step, artprnt, prints the listing. this program is so designed that it can print either the agency field or the subject field on the left-hand side of the page; it also permits printing or omitting agency state or agency country, or both. a completely separate program, called artupdt, enables the librarian to update the master file periodically. it allows addition and deletion of records and changes in records already listed. a special feature of the artread program is worth mentioning. the input record has room for five separate subjects and each subject has room for five separate subdivisions. it is possible to specify an option in artread whereby the subjects in the subject field are rotated so that separate records are created, each with a different subject in the first field. this option would make up to five records out of one. there is also an option enabling a maximum of 25 records to be made out of one, whereby each subject subdivision is printed in the first position in the subject field. these two options are of importance when subject sorting takes place; the latter one is of particular use when subject indexes are printed. an example of the way these options operate is shown below. the original data in field 11: dadaism, french, 20th century; duchamp, marcel, 1887-1968 option 0 will file the original record as: dadaism, french, 20th century; duchamp, marcel, 1887-1968 option 1 will file the same as option 0 and in addition it will file : duchamp, marcel, 1887-1968; dadaism, french, 20th century option 2 will file the same as option 1 and in addition it will file: french, 20th century, dadaism ; duchamp, marcel, 1887-1968 20th century, dadaism, french; duchamp, marcel, 1887-1968 marcel, 1887-1968, duchamp; dadaism, french, 20th century 1887-1968, duchamp, marcel; dadaism, french, 20th century 302 journal of library automation vol. 3/4 december, 1970 option 3 may be used when producing an author listing. when this option is specified, a separate record is created for each second, third, etc. author in permuted order. for example, when field 17 contains: author: lipchitz, jacques; gris, juan; title: juan gris 1887-1927. option 3 creates the additional record: author: gris, juan; lipchitz, jacques title: juan gris 1887-1927. the length of each record is variable, with a limit of 1,223 characters per record, a number arrived at by summing the maximum field lengths observed in a sample of 100 typical records. detailed listings of the programs and program packages ( jcl) are available at the ucsb library systems office. implementation the program packages mentioned earlier were designed for user convenience. a program package is a deck of control cards (ibm jcl) that call on the stored programs, artread, sortd, artprnt, artupdt and artindx when needed, and include all the options required for a particular type of listing. the program package with a current heading card in place and punched data cards inserted is ready for submission to the computer. such a package for an update run is shown in figure 5. i nitialization & ar t read fig. 5. artupdt program package. conclusion update cards go here heading card for update transactions goes here this classical systems development effort has demonstrated that highly versatile systems capable of meeting a wide range of requirements can be listings of uncataloged collectionsjbellomy and jaccarino 303 developed when attention is given to the full scope of requirements the new system may be called upon to meet. that the new computerized procedures are in fact satisfying diverse needs is attested to by the following two statements from librarians using the machine produced lists with different uncataloged collections : virginia smith, arts library, says : "this system of listing art exhibition catalogs has several advantages. the access to each catalog is so much greater than in a standard cataloging system that the regular method seems antiquated. each catalog can be retrieved by almost any kind of information author, title, date, agency (sponsoring or exhibiting institution), city, country, or one of the possible twenty-five subject descriptors. the economy is another advantagethere is a 40% increase in production over the standard cataloging. the processing is simpler and faster, and the end product (computerized printout) is a facile tool adaptable for any level of patron, freshman to doctoral candidate." maria patermann, oil spell information center, reports: "the base of our retrospective search module consists of more than 10,000 citations to a wide range of library materials (journal articles, photographs, newspaper clippings, aerial photographs, maps, films, tapes, texts and monographs) related to major oil spills. the data base is expected to grow to 100,000 items. all material is indexed at an average level of 9.5 terms per item using a controlled vocabulary ( theasaurus) of our own design which must satisfy a wide range of user needs. the system of producing selective listings can serve well. its major advantage is providing access to a multi-discipline, multiform collection and the elimination of duplicate processing operations. the multiple subject entries make it unnecessary to obtain more than one copy of any document. the reduction of search time and the flexibility of refining the thesaums with a built-in weeding capability are the most important benefits for our growing collection. input can be prepared by non-professionals an economic advantage which offsets, to some extent, the cost of keypunching operations. this automated system is expected to become an attractive customer service in that it gives a dynamic impact of selected information from a large data bank." acknowledgments the system described in this document is the work of many hands, and without the encouragment of the university librarian, donald c. davidson, and the assistant university librarianservices, eugene e. graziano, and the enthusiasm of the head of the arts library, william r. treese, these pr<:>grams might never have been developed. presidents it is with great pleasure that i bring you greetings as your lita president. it is an honor to be the lita president and to follow the very productive term of tom wilson. as you know, this column is an opportunity for the president to increase communication with the membership. as lita president, i plan to concentrate my efforts on continuing to capitalize on the association’s many strengths. last year at lita’s 2004 town meeting at ala midwinter meeting in san diego, we built on the planning efforts of tom wilson. to assist in the development of goals to support lita’s developing vision statement, i gathered additional information for the next planning phase. i asked the town meeting’s more than eighty attendees to consider these three questions. 1. what do you like about lita, its organizational structure, and its programs? 2. what services or products does lita currently offer that you value? 3. what new services or products would increase lita’s value to you? the attendees gathered at small tables and discussed the three questions. after the discussions, each table shared their answers. here’s what they thought: 1. what do you like about lita, its organizational structure, and its programs? � easy to become involved � inviting � great networking � forward thinking � lack of bureaucracy � flexibility � enthusiasm of members � encourages discussion � openness to new members � open structure 2. what services or products does lita currently offer that you value? � lita_l � regional institutes � top tech trends � ter � national forum � ital � lita publications � interest groups � programming � networking with knowledgeable people 3. what new services or products would increase lita’s value to you? � coordination with other divisions � liaison at state levels � mentoring (partnering with nmrt) � leadership in advising libraries � best practices and competencies � more standards involvement � more access of those not attending conference � webcasts in one-to-two-hour sessions � partnerships with vendors � more diversity in the organization � conference reports � use more leading-edge technology � more content on the web site � more focus on technical issues � blogging � online newsletter � announcement service � mechanism for sharing information � another electronic discussion list for tech how to’s � tech reviews and recommendations � online community support � rss feed on the web site � stronger voice on technology and policy � semiannual e-mail messages to all lita members as you can tell from these comments, lita provides many valuable services to our members, and to the association at large. however, there are many opportunities for us to do more. to accomplish the goal of expanding our services and setting priorities, we have continued our emphasis on strategic planning activities. along with mary taylor, lita’s executive director, i attended several alaahead planning sessions last fall. our participation in these meetings reinforced our commitment to the planning processes we used to draft lita’s goals and strategies for the next five years. this draft plan is scheduled for review by the lita board during the 2005 ala midwinter meeting. additionally, lita’s strategic plan will be discussed at the 2005 lita town meeting, also during midwinter meeting. we look forward to finalizing our strategic plan by the 2005 ala annual conference. i believe this plan will help us achieve our goals and be used to gauge our successes. in addition to our strategic planning process, lita has made great strides in a number of significant areas. the lita web advisory task force, chaired by zoe stewart marshall, has been working to “establish policies governing the lita web site’s content, responsibilities for its management, and an approval process for posting content 2 information technology and libraries | march 2005 president’s column colby mariva riggs colby mariva riggs is lita president and project coordinator, library systems, university of california–irvine. (continued on page 31) online.” they have implemented several process improvements already and will complete their work by the 2005 ala annual conference. this past fall, michelle frisque, lita web manager, conducted a survey of our members about the lita web site. michelle and the web coordinating committee are already working on a new look and feel for the lita web site based on the survey comments, and the result promises to be phenomenal. on top of all of the current activities, new vision statement, strategic planning, and the lita web site redesign, mary taylor and the lita board worked with a graphic designer to develop a new lita logo. after much deliberation, the new logo debuted at the 2004 lita national forum with great enthusiasm. many members commented that the new logo expresses the “energy” of lita and felt the change was terrific. with your help, lita had a very successful conference in orlando. although there were weather and transportation difficulties, the lita programs and discussions were of the highest quality, as always. the program and preconference offerings for the upcoming annual conference in chicago promise to be as strong as ever. don’t forget, lita also offers regional institutes throughout the year. check the lita web site to see if there’s a regional institute scheduled in your area. lita held another successful national forum in fall 2004 in st. louis, “ten years of connectivity: libraries, the world wide web, and the next decade.” the threeday educational event included excellent preconferences, general sessions, and more than thirty concurrent sessions. i want to thank the wonderful 2004 lita national forum planning committee, chaired by diane bisom, the presenters, and the lita office staff who all made this event a great experience. the next lita national forum will be held at the san jose marriott, san jose, california, september 29–october 2, 2005. the theme will be “the ubiquitous web: personalization, portability, and online collaboration.” thomas dowling, chair, and the 2005 lita national forum planning committee are preparing another “must attend” event. next year marks lita’s fortieth anniversary. 2006 will be a year for lita to celebrate our history, future, and our many accomplishments. we are fortunate to have lynne lysiak leading the fortieth anniversary task force activities. i know we all will enjoy the festivities. i look forward to working with many of you as we continue to make lita a wonderful and vibrant association. i encourage you to send me your comments and suggestions to further the goals, services, and activities of lita. 32. terence cavanaugh, “e-books and accommodations: is this the future of print accommodation?” teaching exceptional children 35, no. 2 (2002): 56–61. 33.

both quantitative and qualitative research methodologies were adopted to analyze the current status of legislative principles related to digitization through the literature review and the circumstance of the latest projects related to digitization through the literature and website review. the results showed that these institutions seem quite successful where they provide a wide range of services for the users to access the digital collections. however, the main constraints on digitization within libraries, archives, and museums in russia are connected with the scale of the work, dispersal of rare books throughout the country, and low level of document usage. introduction culture is one of the most important aspects of human activity. libraries, archives, and museums (lams) in the russian federation store some of the richest cultural and historical heritage collections, some of which can be classified as world cultural treasures. as is true with other countries, lams in russia are engaging in problems with digitization of their unique cultural treasures. in this regard, these repositories are implementing digital technologies to improve their work on digitization, preservation, indexing, search, and access of cultural heritage more effectively and efficiently. information technologies can be used to preserve national knowledge and experience.1 the digitization of cultural heritage is one of the changes that occurred at the present stage of the global information society. researchers have made many attempts to define the concept of digital culture, which is considered to be a phenomenon that manifests itself through art, creativity, and self-realization, by implementing information technologies.2 the need for digitization of unique cultural heritage has caused the rapid development of digital libraries, archives, and museums, described collectively as digital lams, the multidisciplinary institutions that change the way people retrieve and access information. researchers and specialists involved in the digitization of information resources in lams work together to preserve the cultural heritage of the russian federation using modern information technologies. as pronina noted, the digitization of cultural heritage began to develop actively in many countries, including russia, around the same time.3 many researchers analyzed digitization issues in russia. for example, lopatina and neretin discussed the modernization of the system of cultural information resources and the history of preserving digital cultural heritage in russia.4 astakhova pointed out the problem of the digitization of cultural heritage and the transformation of art objects into 3d models.5 miroshnichenko et al. discussed the problem of organizing digital documents in the state archives and pointed out the issues of providing digitized archival documents for wide access through open electronic resources.6 mailto:heesop@knu.ac.kr mailto:nadyamaltceva7@gmail.com information technology and libraries december 2022 digitization of libraries, archives, and museums in russia | kim and malceva 2 despite a long history of improvements in digitization policies and programs, issues still exist in the major cultural repositories, and russia’s level and scope of digitization research are still lagging behind many european countries.7 therefore, three primary research questions guide this study: 1. what is the policy to regulate the digitization of cultural heritage in russia? 2. what is the status of the digitization of cultural heritage in russia? 3. what are the constraints related to digitization in russia? in addition, there is not enough research that fully reflects the current activities of digitization practices in lams in russia. by analyzing this matter, the authors hope to present the state of cultural heritage digitization in russia and uncover problems and limitations in this field. benefits of digitization in a cultural heritage repository before answering the key research questions, it is worth exploring the ultimate benefits of digitization in cultural heritage repositories. digitization refers to converting an analogue source into a digital version.8 a large proportion of the collections related to cultural heritage repositories comprise not only the materials that are born digital, but many resources that are not originally created in digital form that have been digitized. digitization involves three major stages.9 the first stage is related to preparing objects for digitization and the actual process of digitizing them. the second stage is concerned with the processing required to make the materials easily accessible to users. this involves a number of editorial and processing activities including cataloguing, indexing, compression, and storage, as well as applying appropriate standards for text and multimedia file formats to meet the needs of online digital lams. the third stage includes the preservation and maintenance of the digitized collections and services built upon them.10 the benefits of digitization are improved access and preservation. items, once digitized, can be used by many people from different places simultaneously at any point in time. unlike printed or analogue collections, digitized collections are not damaged by heavy and frequent usage, which helps in the preservation of information. according to ifla’s guidelines, several benefits come from having digitized materials. organizations digitize 1. to increase access to a high demand from users and the library or archive has the desire to improve access to a specific collection; 2. to improve services to an expanding user’s group by providing enhanced access to the institution’s resources with respect to education and life-long learning; 3. to reduce the handling and use of fragile or heavily used original material and create a backup copy for endangered material such as brittle books or documents; 4. to give the institution opportunities for the development of its technical infrastructure and staff skill capacity; 5. to form a desire to develop collaborative resources, sharing partnerships with other institutions to create virtual collections and increase worldwide access; 6. to seek partnerships with other institutions to capitalize on the economic advantages of a shared approach; and 7. to take advantage of financial opportunities, for example the likelihood of securing funding to implement a program, or of a particular project being able to generate significant income.11 information technology and libraries december 2022 digitization of libraries, archives, and museums in russia | kim and malceva 3 while digitization has benefits, there are also some problems. the most obvious one is related to the quality of the digitized objects. in the course of digitizing, we may lose some important aspects of the original document. another problem is related to access management. proper mechanisms need to be put in place to determine the authenticity of materials, as well as to control unauthorized access and use. the success of digitization projects depends not only on technology but also on project planning. since digitization is a relatively new process, institutions may concentrate on technology before deciding on a project’s purpose. however, technology should never drive digitization projects; instead, user needs should be determined first, and only then should a technology appropriate to those needs be selected to meet a project’s objectives. the best practices for planning a digitization project can be suggested as follows: determine the copyright status of the materials; identify the intended audience of the materials; determine whether it is technically feasible to capture the information; insist on the highest quality of technical work that the institution can afford; factor in costs and capabilities for long-term maintenance of the digitized images; cultivate a high level of staff involvement; write a project plan, budget, timeline, and other planning documents; budget time for staff training; plan a workflow based upon the results of scanning and cataloging a representative sample of material.12 policies regulating digitization of cultural heritage in russia the policy development at the time of selection should be made early for the suitability of selection and digital object management. this policy should formulate goals of the digitization project, identify materials, set selection criteria, define the means of access to digitized collections, set standards for image and metadata capture and for preservation of the original materials and state the institutional commitment to the long-term preservation of digital content.13 as stated by russian law, the cultural heritage of the peoples of the russian federation includes material and spiritual values created in the past, as well as monuments and historical and cultural territories and objects significant for the preservation and development of identity of the russian federation and all its peoples, their contribution to world civilization.14 the decree of the president of the russian federation “on approval of the fundamentals of state cultural policy” extended the term of cultural heritage by including documents, books, photos, art objects, and other cultural treasures that represent the knowledge and ideas of people throughout the centuries. the government emphasized the role of the information environment and modern technologies by analyzing it at the legislative level. in the presidential decree “on approval of the fundamentals of state cultural policy,” the concept of the information environment is separately distinguished, defined as a set of mass media, radio, and television broadcasting, and the internet; the textual and visual information materials disseminated through them; as well as the creation of digital archives, libraries, and digitized museum collections.15 another important part of the government policy is to provide open access to cultural heritage objects. the problem of access was confirmed in the state program culture of russia (2012 –2018), which stipulated the need to provide access to cultural heritage in digital forms as well as to create and support resources that provide access to cultural heritage objects on the internet and in the national electronic library, one of the main digital repositories in the country.16 access to digital cultural heritage was also considered in the state program information society (2011–2020). the subprogram information environment ensured equal access to the media environment, including information technology and libraries december 2022 digitization of libraries, archives, and museums in russia | kim and malceva 4 objects of digital cultural heritage. the program aimed to reduce the gap in access to cultural heritage objects in different regions across the russian federation.17 the digitization of cultural heritage and creation of digital archives is one of the characteristics of innovative changes in the cultural sphere of the information society. the law “on archival affairs” notes that a significant part of the information resources of the archives has a historical and cultural value and should be considered as part of the digital cultural heritage collection, the digitization of which is required.18 with regards to libraries, on january 22, 2020, the state duma of the russian federation adopted the draft law “on amendments to the federal law on librarianship” in terms of improving the procedure for state registration of rare books (rare books are defined as handwritten books or printed publications that have an outstanding spiritual or material value; have a special historical, scientific, cultural significance; and for which a special regime for accounting, storage, and use has been established) that aimed at ensuring legal protection of rare books by improving the system of protection of the items of the national library. the law reflects the criteria for classifying valuable documents as rare books and fixes the main stages of their registration. in case of museums, a federal law from 1996 aimed to establish the national catalog of the russian federation museum collections. at first this national catalog was created for inventory purposes and then it was transformed into an online database to ensure open access to russia’s cultural heritage (http://kremlin.ru/events/administration/21027). annual reports “on the state of culture in the russian federation” reflect the overall situation and changes in libraries, archives, and museums. some researchers emphasized the need to develop a unified regulatory framework for cultural heritage preservation practices. particularly, shapovalova stressed that the leader in this discussion should be the government, which plays a crucial role in the legal regulations of the cultural heritage policy and is responsible for the development of initiatives.19 however, lialkova and naumov criticized that russian policy discusses digitization of only a few cultural objects, but does not define the legal status of such objects and does not cover objects originally created in a digital form.20 kozlova considered the issues of russian digital culture within the framework of the obligatory library copies system.21 since 1994, the national library of russia has accepted electronic media according to the federal law “on the obligatory copy of documents,” which established the legal deposit system; the bibliographic records of deposited electronic media are available online in the electronic catalog “russian electronic editions.” acquisitions librarians use this catalog as a national bibliographic resource for adding electronic editions to their collections. dzhigo addressed issues of digital preservation of cultural heritage and also paid attention to the federal legal deposit law.22 yumasheva dealt with the content of the russian normative methodic of regulating the process of digital copying of historical and cultural heritage from russian libraries and museums.23 kruglikova considered theoretical and practical issues of legislation for the preservation and popularization of cultural heritage in the modern world.24 shapovalova suggested introducing the terms of digital cultural heritage objects on a legislative level, to recognize the concept of preserving cultural heritage and to provide virtual access to such objects on the bigger scale.25 a review of the literature reveals various studies that discuss cultural heritage preservation using modern technologies. the majority of researchers identified issues in this field. digitization practices are carried out mainly by the state libraries, archives, and museums which seek to http://kremlin.ru/events/administration/21027 information technology and libraries december 2022 digitization of libraries, archives, and museums in russia | kim and malceva 5 preserve cultural heritage objects in a better methodological and legislative way, and less development is seen in smaller local lams. researchers express the value of preservation of cultural materials and the need to analyze and improve legislative procedures. to this day government realizes the importance of digital preservation; however, the term “digital cultural heritage” is not mentioned and the legal status of such digitized objects is not defined. in addition, legislative documents do not cover the regulation of objects originally created in digital format. moreover, we can see a large gap between the accumulation of materials and the degree of their use despite the fact that the government seems to support open access to digital cultural heritage objects. digitization projects of cultural heritage in russia to analyze the circumstances of the latest projects related to digitization, we investigated the relevant websites from may 2021 to june 2022. in this study, we chose a few representative institutions, including some national projects, based on their reputation, authority, and the scope of the collections. the data on digitization practices and current projects were collected . the list of institutions is shown in table 1. as shown in table 1, the authors selected russian national library, national electronic library, russian state library, and presidential library as the largest and most well-known libraries in russia. among the archives chosen for the analysis, the archival fonds was selected because it unites the archives in russia in one system, and the national digital archive was selected because its main goal is to preserve and archive key russian digital resources. as for the museums, the state hermitage museum, the state russian museum, and the state museum of fine arts named after a. s. pushkin were chosen for this study because they hold the richest collections of russian cultural heritage and play a vital role in replenishment of the national catalogue of the russian federation museum collections, the main goal of which is to unite museums across the country. by analyzing the websites of these selected libraries, archives, and museums, we can gain insight into what projects have been undertaken to preserve cultural heritage and what are the main drawbacks of this field. however, it is true that some institutions do not share the latest information on digitized items. in the case of libraries and archives, the numbers are fairly public on the website, but it is difficult to prove exactly when the objects were digitized. however, not all museums share information about recently digitized objects. in this case, quantitatively analyzing digitization practices is the only way. therefore, the authors used a manual method for data collection and counted the number of digitized materials available on the website. indeed, this could be one of the limitations of this work, as some institutions have hidden the exact amount of digitized collections; some institutions have not been able to manually count digitized copies due to huge amounts of data; and some websites may not be up to date. information

biryukova et al. reviewed the interdisciplinary approach to preserving cultural heritage and creating virtual museums.29 povroznik also analyzed virtual museums that preserve the cultural heritage of the russian federation.30 the author concluded that virtual museums and its resources need to be studied, developed, and improved more. kondratyev et al. considered the issues of digital heritage preservation from the security, integrity, and accessibility perspective, and analyzed the concept of a smart museum.31 lapteva and pikov represented the experience of the students of the institute for the humanities of siberian federal university working with the state russian museum and the state hermitage museum, the leading russian museums that are playing the important role in country digitization practices.32 the authors noted that results of implementing modern information technologies in museums create a comfortable infrastructure for the audience by preserving and representing cultural heritage in interactive contexts. information technology and libraries december 2022 digitization of libraries, archives, and museums in russia | kim and malceva 10 findings digitization in russian libraries creating a digital collection has become a normal library activity in russia.33 within the framework of the main development of activities to preserve russian library collections from 2011 to 2020, one of the main programs of the national library is the digitization of rare books. rare books, according to the federal law “on amendments to the federal law on librarianship,” include handwritten books or printed publications that have outstanding material value or special historical, scientific, and/or cultural significance.34 thus, the law elevated the book to the same level of protection as other objects of cultural heritage at the national level. the website of the register of rare books (https://knpam.rusneb.ru), hosted by the russian state library, became a part of the national library collection preservation program developed in 2001. from 2001 to 2009, the subprogram rare books of the russian federation was created to provide a regulatory framework and methodological support for all areas of library activities related to the preservation of library collections. this program includes not only libraries but also other institutions such as museums, archives, and scientific and educational institutions. however, in order to implement the state registration of rare books, it is necessary to further develop regulatory documents that can control the reference procedure and registration procedure of rare books. another initiative for book preservation is the federal project digital culture, designed to provide citizens with wide access to the country’s unique cultural heritage. it was expected that ten to twenty libraries of different russian regions will take part in the digitization project, each offering at least 50 documents from their collections to the project. however, the problems of this program are related to the work scale, as well as the dispersal issue of rare books throughout the country. as the 2011–2020 library preservation report emphasizes, many of these rare books remain unknown to the wider scholarly community. approximately half of the valuable collections available in the country’s repositories are not described as integral objects of cultural and historical heritage. the russian state library noted that the main problems associated with rare books include comprehensive function to identify and record rare and valuable books; ensuring the safety and security of the books; copying valuable materials requires special equipment; and the need for proper storage as the most important condition for the preservation. another main center of digitization is the digital library of the national library of russia (nlr, https://nlr.ru). the digital library is an open and accessible information resource that includes over 650,000 digitized copies of books, magazines, newspapers, music publications, graphic materials, maps, plans, atlases, and audio recordings. the digitized materials include items from the holdings of the national library of russia, partner libraries, publishing organizations, authors, and even readers. for now, the digital collection of the library includes various collections such as landmarks of the nlr, rare books, rossica, maps, and manuscripts. hosted by russia’s national library in 2004, the national electronic library (nel, https://rusneb.ru/) was launched to create an electronic library sponsored by the russian federal ministry of culture. the nel is a service that searches the full text of scanned books and magazines that have been processed using optical character recognition and converted them into text. it is stored in a digital database available through the internet and mobile applications. one of the main tasks of the nel is the integration of the libraries of the russian federation into a single information network. as of june 15, 2022, the nel collection had a total of 5 million artifacts including electronic copies of books, educational and periodical literature, dissertations and https://knpam.rusneb.ru/ https://nlr.ru/ https://rusneb.ru/ information technology and libraries december 2022 digitization of libraries, archives, and museums in russia | kim and malceva 11 abstracts, monographs, patents, notes, and visual and cartographic publications. the russian state library became the main operator of the national electronic library project in 2014. since 2015, the national library of russia has expanded its digitization program and the site now publishes a list of publications that require digitization. readers vote for publications directly on the site by clicking the vote for digitalization button. for example, as of november 2020, a list of 1,998 publications on a variety of topics ranging from physics and mathematical literature to psychology and music was available for voting. digitization in russian archives archives have historical, scientific, social, and cultural significance, which is an essential part of the process of preserving russian cultural heritage. digitization projects in russia began as an element of the digital cataloging of the largest archives from the 1980s to the 1990s. initially, the main purpose of the digitization project was to create digital copies to ensure the preservation of original archive documents and to eliminate the distribution of rare or poor originals in the reading room. since then, digitization has become an integral part of creating digital archives in russia.35 currently, one of the main goals of digitizing archival documents is to provide open access to legal entities and individuals to archival documents from the russian federation. the main archival center is the archives fond of the russian federation (http://archives.ru/af.shtml). the archives fond has more than 609 million items from the early eleventh century to the present and performs important functions to preserve historical memory, replenish information resources, and provide access to the public. the main task of digitization is to preserve russia’s cultural and historical heritage. each year, the total volume of archives across russia increases by an average of 1.7 million items. despite the relatively small amount of equipment for digitization, we can still see progress. in 2015, 8,750 documents were digitized, while in 2019, the annual total had reached 27,518 documents. this increase in the number of digital documents shows that digital copy production is directly related to equipment acquisition. however, the researchers found that the level of use of these documents was not high and tended to decrease. for example, in 2015, there were 18,155 document views, while in in 2019, there were only 19,417 document views. therefore, it is necessary not only to promote the service of the archive agency but also to increase the demand for archive documents. a portal was created under the auspices of the archives fond of the russian federation (http://www.rusarchives.ru) to encourage archiving services for users and to organize all archives throughout russia. the portal collects information resources of russian archives on the internet and publishes archival directories and regulations. the establishment was an important breakthrough in organizing access to the documents of the archives fond of the russian federation. since 2012, the website has operated the central catalog software complex, which provides information on the composition of federal and regional digitized fonds. as reported by the federal archival agency, 32 virtual exhibition projects are posted on the official website and portals of the federal archival agency. this website provides information about online archive projects, including virtual exhibitions, digital collections, and inter-archive projects. users can search for materials on the website by three publication types: virtual exhibition, document collection, and inter-archive project. the project covers four subjects: the great patriotic war, statehood of russia, soviet era, and space exploration. the federal archival agency’s main website also provides five catalogs and databases that guide users through digitized collections. this list includes the central stock catalog

(http://cfc.rusarchives.ru/cfc-search), state register of unique documents (https://unikdoc.rusarchives.ru/), guides to russian archives (https://guides.rusarchives.ru/), electronic inventories of federal archives (https://rusarchives.ru/elektronnye-opisi-federalnyharhivov), database of declassified cases and documents of the federal archives (http://unsecret.rusarchives.ru/), and database on the places of storage of documents on personnel (http://ls.rusarchives.ru/). as of january 1, 2022, 859 documents were included in the state register of unique documents of the archival fund of the russian federation. a total of more than 98,000 documents are stored in the database. a project to digitize documents from the soviet era is still in progress, and the new collections of digitized copies of archival documents stored in federal archives across russia will be displayed on the website in the future (http://sovdoc.rusarchives.ru/#main). one of the major drawbacks of the digitization process in russia is that archival agencies and cultural heritages are scattered throughout russia. to develop digital archiving initiatives in different regions of russia the culture of russia (2012–2018) program was developed. archives of the constituent entities of the russian federation can take part in this program and get funding from the regional budget to digitize collections as a part of the regional program for the development of archival affairs.36 despite some improvements and ongoing projects, there are still no initiatives for the long -term preservation of born-digital materials and no requirements for mandatory long-term preservation of information. however, the national digital archive (https://ruarxive.org) was created to find and preserve websites and other digital materials that have a high public value and are at risk of destruction. this initiative proposes the general idea of archiving modern digital heritage and consists of many projects. the main one is preserved government, which aims to preserve official materials in the following areas: official accounts on social networks; official sites of government managers, officials, political parties; historical documents; and especially databases. future plans include developing tools that will help collect digital materials faster and more efficiently and also better systematize what has already been collected. digitization in russian museums the active introduction of information technology into museums began at the end of the twentieth century. a new area of study, museum informatics, has emerged in russian higher-education institutions. this area of study focuses on museum work and modern information technology to develop and improve museum activities.37 museums have developed many digitization projects to preserve their collections and give free and easy access to cultural heritage items. the modern russian museum system consists of about 2,773 museums, although the exact number of museums is not known. since the 1970s, the rationale for russian museum digitization practices has been quite similar to that of many other countries, finding that information and collection management are needed to ensure that museum objects are listed and properly preserved. the museums plan to create electronic collections, open valuable collections to the public, create a state catalog of the museum collection of the russian federation (https://goskatalog.ru/portal/#/) and integrate all works from all museums in russia. as of 2020, more than 23 million museum items are registered in the national catalog of the museum collection. the catalog is planned to be complete by 2026, when metadata and images of the museum’s collection are included in the register and posted online. digitization of museum collections is an important process that has recently received stable support from the government. http://cfc.rusarchives.ru/cfc-search

digitization of libraries, archives, and museums in russia | kim and malceva 13 the national information society (2011–2020) program includes a project to create a new virtual museum based on the collections of the country’s largest national museum. the term “virtual museum” is used to characterize various projects linked to digital technology in virtual and museum space.38 it can be represented by a collection of works of art on the internet and the publication of the museum’s electronic expositions. currently, there are about 300 virtual museums available in virtual form across the country (https://www.culture.ru/museums). the most-visited museums are the state hermitage museum in st. peterburg (https://www.hermitagemuseum.org/), the state tretyakov gallery (https://www.tretyakovgallery.ru), and the state russian museum (http://en.rusmuseum.ru). these museums offer users a wide range of activities, including the use of modern technology . for example, since 2003 the russian art collection at the state russian museum (the world’s largest museum) started to implement the russian museum: virtual branch project, opening virtual branches in museums, universities, cultural centers, and institutions of additional education around the country. thanks to computer technology and digitization, thousands of russian residents in near and far places have access to the value of russian culture, russia’s historical and artistic past, and the richest collection of russian art. international business machines (ibm) collaborated with the hermitage museum to make it one of the most technologically advanced museums in the world. ibm built the state hermitage museum website in 1997, later called the “world’s best online museum” by national geographic traveler.39 the hermitage has unique experience in developing digitization programs and uploading collections to websites. currently, the museum collects more than 3 million items, and the online archives presented on its website provide easy search and the possibility of creating your own collection on the website. in 2020, the hermitage released a documentary feature film in virtual reality (vr) format, “vr— hermitage: immersion in history with konstantin khabenskiy” (https://www.khabenskiy.com/ filmography-vr-hermitage-immersion-in-history-with-konstantin-khabenskiy/). visitors can tour the history of the hermitage in a vr format based on the most important events in the history of the hermitage from the eighteenth century to the present. the pushkin museum, the largest museum of european art in moscow, offers another example of using vr technology. the joy of museums offers virtual tours of more than 60,000 museums and historic sites around the world, including the pushkin museum (https://joyofmuseums.com/museums/russianfederation/moscow-museums/pushkin-museum/). virtual museums can display electronic versions of exhibits longer than actual museum exhibitions limited by region and time zone and have the means to record information about past exhibits, including electronic collections of exhibits, as well as data on opening times and concepts. for example, the website of the state tretyakov gallery contains a virtual archive of past exhibitions. therefore, the virtual museum has considerable research potential and is actively contributing to the preservation of cultural heritage. digital copies of the original culture and arts form an electronic archive of great value from two perspectives. this is the preservation of rarity for future generations, the broad access of users to the rarest and most unique artworks in historical significance, and the possibility of research. on the other hand, it is an opportunity to find commercial use of artifacts, additional sponsorship, and investment proposals for museums. conclusions and further study the two most obvious benefits of digitization are improved access and preservation, so that libraries, archives, and museums can represent russian culture and introduce rare and unique cultural heritage artifacts to future generations. in this work, we have addressed some legislative

and malceva 14 principles and outlined major digitization projects. the general problem of digitization in russia is related to the size of works, the tendency of documents to decrease without high use, and the scatter of rare books nationwide. in the case of libraries, one of the problems of digitization is also related to the uneven distribution of rare books throughout the country. the most important materials are concentrated in the largest federal library, and many rare books are housed in many central libraries in various parts of the russian federation. work using book memorials should be planned as long-term activities performed at different levels. in the case of archives and museums, one of the major drawbacks of the digitization is the dismantling of national archives and cultural heritages. based on this preliminary study, there are several further research topics that can enhance understanding of digitization of cultural heritage in russia. in particular, since digitization is a complex process that requires both management and technology, future research needs to be divided into three aspects: management, technology, and content. endnotes 1 g. a.

research department, international center for scientific information, moscow, ussr 61 a recursive presentation of a communication format is discussed and a form of pertinent notation proposed. recursive notation permits presentation of an interchange format in more general terms than heretofore published, and expands application possibilities. the development of the forms of exchange of information among documentation systems, and particularly the development of the technique of recording machine readable bibliographic data on magnetic tape, has led to the requirement for the adoption of an agreement on a standard for a format for communication. thus, the problem of a format for communication reflects the existing tendency toward ensuring compatibility among formats. at the present time the greatest impact on world information practice has been caused by the american national standard institute (ansi) standard for bibliographic information interchange on magnetic tape ( l ) and the several implementations of that standard: marc, inis, cosati and others. it should be noted that, despite numerous existing peculiarities, in principle there is no difference in structure among the formats. one of the most important requisites for a communication format is universality. the practice of processing large quantities of information has emphasized the flexibility of the above-mentioned formats; their use has permitted identification of huge numbers of documentary materials in 62 journal of library automation vol. 4/2 june, 1971 various forms, thereby creating the impression that the structure of the format has been developed to such an extent that it can be canonized for any application. it must be said that support or rejection of this impression can be based only upon future experience in the application of a communication format. nevertheless, it appears expedient to generalize about the structure of a communication format by making a few preliminary remarks and thereby contributing toward expanding the sphere of its application. the remarks deal with the following. in the existing systems for interchanging information on magnetic tape, the document is the object of identification. with the development of data banks the characteristics of the objects to be identified may prove to be so varied, even though presented in the proper documentary form, that their uniform presentation will cause difficulties. (actually, examples can be given of data banks in which data appear in the capacity of objects : information regarding firms, rivers, information about products of the electrical engineering industry, etc.). furthermore, even if it is possible to identify in principle a certain object with the aid of the format, one must distinguish between the question of possible identification in principle, and that of the optimal (or rational) form of identification in view of the limitations of a certain system. the recursive notation of a communication format is presented below. certain definitions and ideas in general are used as source material for such a notation, using the american standard for bibliographic information interchange on magnetic tape ( 1). it must be conceded that the use of one term or another for defining individual elements of a notation, as well as the general structure of the entire notation, are not the principal subject of discussion here; this means that any change, either in definition or, to a certain extent, in the structure of the notation, will not affect the proposed form of the notation. consequently, this article does not pretend to describe a certain universal structure for a communication format. it has a different purpose, viz., to point out wider perspectives that will unfold by applying the recursive presentation of notations in formats at the expense of an object with any hierarchical depth. for the following symbols explanations can be found in the ansi standard ( 1 ) : r=record l=leader dr= directory t=tag d=data, or data elements ft=field terminator, or field separator rt=record terminator, or record separator the concept tt used below, and standing for tag terminator, is analogous to ft and rt. so also is the concept sf, meaning specific fields for de· d efinition of communication formatjsumarokov 63 fining contents that did not appear in the proposed notation although utilized in actual formats. the following symbols are also used : tg=tag generalized f=field df=data field bf=bibliographic fields utilization of special notation in brackets (analogous to the form used in algorithmic languages) enables r to be defined in the form of the following consecutive structure: 1) r=[l] [dr] [sf] [bf] the symbols written in brackets after the equal sign maintain the relationship of priority. further, the recursive universal tag tg is defined as follows: 2) tg=[t;tt] such a notation indicates that the expression in brackets is t or tt. the recursiveness of the notation indicates that it is possible that tg is t1t2 ... tp :tt where p is any whole number, a larger or an equal unit. (obviously p defines the depth of the hierarchic description in accordance with the given characteristic. ) finally 3) f=:[tg] [d]; 4) df=: [f;ft] ; 5) bf=: [df;rt]. thus, the general notation of the format is expressed by 1), in which the element bf, which constitutes the basic part of the so-called alternate fields , is expressed recursively with the aid of the system 2) -5 ). as is evident, the quantity f in df, and df in bf, as well as in the case of the subscripts tg, can arbitrarily be a whole number, changing from notation to notation. reference l.

open education programs grow, it is imperative that we integrate practices in our workflows that prioritize and include end users. although there is information available on best practices for user testing and accessibility compliance, more can be done to give insight into the library publishing context. this study examines the user and accessibility testing workflow during the modification of an existing open textbook using pressbooks at texas tech university. introduction as library publishers and open education programs grow, there is an opportunity to integrate into our workflows practices that prioritize and include end users. although there is information available on best practices for user testing and accessibility compliance, more can be done to give insight into the library publishing context. there are currently no case studies that examine the user and accessibility testing workflow during the modification of an existing open textbook. this study examines user experience testing as a method to improve oer interfaces, learning experience, and accessibility during the oer production process using pressbooks at a large research university. literature review user experience (ux) is a “momentary, primarily evaluative feeling (good–bad) while interacting with a product or service” that can go beyond simple usability evaluations to consider “qualities such as meaning, affect and value.”1 ux evaluations are generally applied to library websites, spaces, and interfaces and are not currently a common element in library publishing workflows. open educational resources (oer) are defined as teaching, learning, and research resources that reside under an intellectual property license that permits their free use and repurposing by others.2 whitfield and robinson make a distinction between teaching vs. learning resources, instructional vs. interface usability, and ease of modification for creators.3 this select literature review considers usability testing of e-books, oer workflows, and accessibility evaluations and how they apply to local contexts. along with incentives for instructors to engage with oer, the ability to adapt oer is o ften highlighted as a benefit. walz shares common workflows for oer production, including broad steps for design and development during creation of original oer.4 in the case of reuse, the design stage in walz’s workflow includes review, redesign, redevelopment, and adoption. open university models for transforming oer include the integrity model, in which the new oer remains close to the original material; the essence model, in which material is transformed by mailto:cthomas5@fsu.edu mailto:kimberly.vardeman@ttu.edu mailto:jingjing.wu@ttu.edu information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 2 reducing some features and adding new activities for interactivity; and the remix model, in which content is redesigned to be optimal for web viewing.5 student participation in oer production is often seen in open pedagogy, but these cases look at student frustrations and feedback with the objective of experiential learning, not for usability or evaluation.6 now that oer production has grown in scale, librarians and advocates seek the most effective and sustainable workflows. figure 1. illustrations of two oer lifecycles. this work was adapted by camille thomas from an original by anita walz (2015) under a cc by 4.0 international license.7 in his workflow and framework analysis meinke recommends the inclusion of more discrete steps and believes each institution’s ideal workflow will be based on local context.8 usability testing is a discrete workflow step that gives us human-centered insight about how users are affected by interfaces and how they value systems.9 libraries favor collections-based assessment that measures how many end users are using digital items, without prioritizing who users are or how and why they use resources.10 demonstrating and assessing value is essential for scholar buy-in and content recruitment, for example, which are central to all types of open resources. in the case of educational materials, lack of engagement and breakdowns in learning can be attributed to barriers and marginalization of learners.11 additionally, critiques of oer include assumptions that access to information equates to meaningful access to knowledge, but withou t context there is no guarantee that there will be meaningful transference or learning.12 harley believes defining a target audience and considering reasons for use and nonuse of resources in specific educational contexts beyond measuring anecdotal demand (e.g., website page views or survey responses, which harley does not see as indicators of value but rather of popularity) may address challenges to effectively measuring outcomes for content that is freely available on the web.13 meaningful evaluation of learning resources requires deep understanding of contextualized information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 3 educator and student needs, not just content knowledge.14 to address these barriers and assumptions, openstax, a leading oer publisher, has ux experts on staff, but this model is exceptional and rare at a university or library. many universities and libraries publishing oer do not have full-time personnel dedicated to review. some library user experience departments have hired content strategists for auditing, analyzing, defining, and designing website content, contentrelated projects, and overall content strategy.15 currently, oer work is rarely included in the scope of library user experience departments. however, limited literature does show the use of ux research methods in library publishing contexts. libraries and support units with few resources can also perform user testing.16 user experience practitioners have established that a low number of test participants—three to five—are enough to identify a majority of usability issues.17 borsci et al. suggest the important aspect is not securing a high-volume sample, but rather finding behavior diversity to make reliable evaluations.18 the number of users required to find diverse behavior can depend on what is being tested. following this standard, the consistent inclusion of user evaluations in oer workflows will not necessarily require large amounts of funding, participants, resources, or time. oer, in particular, are well suited to cumulative, early, frequent, and specific user testing. with their open copyright licensing and availability, oer are an example of the mutable digital content needed for collaboration, cumulative production, and support of networked communities. 19 several studies assert that complete information behavior analysis should be carried out before or during development, not after.20 meinke concludes his workflow analysis by encouraging iterative release in oer production workflows, which aligns with lean and iterative “guerilla” approaches used in libraries to sustainably improve usability.21 iteration is a process of development that involves cyclical inquiry or repetitive testing, providing multiple opportunities for people to revisit ideas or deliverables in order to improve an evolving design until the end goal is reached.22 in the context of design, it is a method of creating high-quality deliverables at a faster rate.23 a cyclical approach also reflects walz’s as well as blakiston and mayden’s workflow visualizations.24 walz asserts that incentives for instructors and the quality of the resources are key factors in advancing adoption, adaptation, and creation of oer.25 harley uncovered disconnects between what faculty say they need in undergraduate education and what those who produce digital educational resources imagine is an ideal state. 26 influence on faculty resource use, including oer, varied by discipline, teaching style and philosophy, and digital literacy levels, with personal preferences having the most influence on decision-making. in the evaluation or tracking stage found in most oer production workflows, we can see the impact of the quality assurance stage. the study by woodward et al. on student voice in evaluating textbooks found that incorporating multiple stakeholders into the process resulted in deeper exploration of students’ expectations when learning. students ranked one oer and one conventional textbook the highest based on content, design, pedagogy, and cost. multiauthored options ranked higher, and texts with examples were seen as more beneficial for distance learners.27 meinke believes unless discrete parts of the development process are identified, it is not useful to signal others to contribute to a project.28 an example of an oer production workflow containing usability considerations is the content, openness, reuse & repurpose, and evidence (corre) framework by the university of leicester (see fig. 2).29 the openness phase of the corre 2.0 framework includes “transformation for usability,” which is assigned to the oer evaluator, editorial board, or head of department.30 versions of the corre workflow were adapted by the information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 4 university of bath and the university of derby in the united kingdom for their institutional contexts. for example, the university of derby assigned “transformation for usability” to a developer. by building usability as a discrete step in oer production workflows, publishers and collaborators can make improvements on pain points, make changes in context, and create clear guidelines for partnerships based on local needs. betz and hall’s study supports considerations for how user microinteractions, or individual actions within a process, can be improved to make them scalable and commonplace in library workflows.31 this can include publishing workflows. for example, a study of oer on mobile devices in brazil found problems related to performance, text legibility, and trigger actions in small objects.32 other guidelines for oer and usability include using high-quality multimedia source material, advanced support from educational technologists, and balancing high and low technology in order to avoid assumptions about learners’ internet connection or devices.33 although usability testing alone is an important part of evaluating a website or product, because the user experience is multifaceted, it is also important to ensure that the product is accessible, meets user needs, and has an appealing design.34 figure 2. corre framework for oer development at the university of leicester.35 accessibility studies also encourage integrating user interactions into the creation workflow. accessibility impacts usability, findability, and holistic user experience. 36 creators and supporting advocates have relied on universal design, web standards, and ada compliance when creating information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 5 accessible digital content, emphasizing that accessible content for those with disabilities means more accessible content for all users.37 areas addressed can include text style and formatting, linking, and alternative text considerations, as detailed in the bccampus open education accessibility toolkit.38 for example, kourbetis and boukouras drew from universal design to create a bilingual oer for students with hearing impairments in greece, incorporating contextual considerations for vernacular languages and other local user needs.39 early efforts toward accessible oer, such as a 2010 framework, prompted critiques from members of the accessibility community and impeded adoption.40 while guides based in universal design offer a starting place and consistent reference, oer advocates could create workflows that support adaptive changes seen in inclusive design. universal design and web standards are fixed, while inclusive design seeks to support adaptive changes as needs evolve and does not treat non normative users as a homogenous, segregated group.41 treviranus et al. go on to state that compliance is not achieved by providing a set of rules, guidelines, or regulations to be followed.42 beyond lack of awareness of accessibility best practices, librarians and creators tend to have little control over customizing proprietary digital content platforms to add local context. 43 the flexible learning for open education (floe) project, for example, aims to integrate automatic and unconscious inclusive oer design through open source tools, but many institutions may not be able to develop such tools to incorporate local contexts.44 both librarians and e-resources vendors have been interested in the features and usability of ebooks to fine-tune their collection development strategies as well as improve the user experience of their platforms. literature shows that most studies about e-books have focused on features or the interface design of e-book reading applications. the recent academic student ebook experience survey showed that three-quarters of survey attendees considered it extremely important or important for e-books to have page numbers for citation purposes.45 this survey and other studies suggest that search, navigation, zoom, annotation, mobile compatibility, as well as offline availability including downloading, printing, and saving, were the most expected features.46 other features, such as citation generation and emailing, were mentioned or tested in some research.47 while using e-books and using e-textbooks may involve the same functionality, the purpose, devices, and user types differ because knowledge transfer is needed in learning. jardina and chaparro evaluated eight e-textbook applications with four tasks: bookmarking, note-taking, note locating, and word searching.48 they found that the interfaces to these common features varied on the different applications. standardization, or at least following general web convention when designing these interfaces, may reduce distractions that keep students from learning. the etextbook user interface can be critical to the future success of e-textbook adoption. although limited research on usability of e-textbooks or open textbooks has been conducted, a considerable number of findings from studies on e-books are relevant and applicable to etextbook projects. the e-book or e-textbook applications usability evaluation methods and results can be borrowed when understanding oer user needs. libraries can apply these e-book usability evaluations to the basic infrastructure of oer, but leverage the local contexts of students, instructors, and institutional culture when adapting the material. the more normalized usability, prototyping, and collaboration are in oer production workflows, the richer the resources and community investment. this approach can address diverse and evolving oer user needs, locally and sustainably, as they arise. our study contributes to the information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 6 literature by examining the impacts of integrating usability testing in an inaugural oer adaptation project at a large research university in the united states. case study the project to adapt the open textbook college success, published by the university of minnesota libraries, for use in the raiderready first-year seminar course, was brought to the texas tech university libraries’ scholarly publishing office by the head of the outreach department in march 2018. the program was deciding between a commercial textbook and the adapted open textbook. the course was offered during each fall semester and had an average enrollment of over 1,600 since 2016. an initial meeting took place and regular weekly meetings were set up afterward to review edits and ensure communication within the original 30-day timeline. it was the first oer production project for the libraries’ publishing program, which had previously focused on open access journals and materials in the repository. originally, we sought to use open monograph press because we had a local instance already installed. however, a platform with more robust formatting capabilities was needed in order to reach the desired product within the timeline. we decided to use the pressbooks pro (a wordpress plugin) sandbox for one project through our open textbook network membership. a rough draft of edits to the original work were already completed. we used a mediated service model, in which librarians performed the formatting, quality assurance, and publishing. this was in contrast to self-service models in which creators work independently and consult with support specialists. the digital publishing librarian and scholarly communication librarian formatted the edits, with html/css customization and platform troubleshooting from the web librarian. other library staff involved in the project included communications & marketing (cover design), the user experience librarian, and the electronic resources librarian (cataloging in the catalog). campus stakeholders and partners included the libraries, the raiderready program, editors, copytech (printers affiliated with the university), the campus bookstore, and the worldwide elearning unit. program partners were enthusiastic about usability and accessibility testing for the textbook. the initial testing took place in the middle of the adaptation project timeline, once initial content was formatted and ready for testing. the bccampus’ accessibility toolkit and the pressbooks user guide were used as primary guides throughout the process. the scholarly publishing librarian and the user experience librarian met to develop the testing method and identify users who would reflect the audience using the textbook. a second round of tests was conducted a year after the initial project when the editors made updates to the text. while the resulting changes were minor, this further testing allowed us to seek more feedback on the most recent version of the textbook and apply some lessons learned from the first round of testing. we did not use personas or identify user needs beforehand. we planned to recruit first-year students and students who took the raiderready course in a previous semester. however, we decided to instead recruit from existing pools of student volunteers for library usability tests in order to get three to six students in a short amount of time. for the second round of testing, we planned to recruit on-campus students, distance students, and students with diverse abilities. we recruited from newly established pools of volunteers for distance students as well as existing volunteer pools. during the first iteration, we requested that worldwide elearning, texas tech university’s distance learning unit on campus, test the textbook pilot content in pdf and epub formats using screen reader software. information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 7 the user experience librarian conducted a first round of four usability tests in march 2018 and a second round of two usability tests in april 2019. a sample test script from steve krug provided a solid foundation for conducting our own tests.49 in each test, participants were asked to answer two pretest questions, complete four tasks, and answer four posttest questions (see appendix for script). tasks included finding the textbook, exploring the textbook itself, locating activities for a specific chapter, and searching for the student code of conduct. participants were instructed to think aloud as they worked through the tasks. the think-aloud protocol is a commonly used test method, where participants are asked to verbalize their thoughts and actions as they perform tasks on a website. the observation tasks are set beforehand, and the facilitator follows a script to ensure consistency among testers.50 the combination of observing and recording participants’ comments and reactions provides insight into a site’s usability. testers were invited to comment on their experience at the end of the session. each usability test was recorded using morae software to track on-screen activity such as mouse movements and clicks, typing, and the verbal comments of the facilitator and participant. we conducted tests using a laptop running windows 10 with a 15.6-inch display. in the first round of testing, we also showed students the book on an ipad mini, both in adobe reader and ibooks. while we asked them to briefly view the textbooks, we did not ask them to complete specific tasks while using the tablet. limitations the biggest limitation was that we did not test on users using a screen reader or other assistive technology. the user experience librarian built a pool of on-campus students who volunteered to participate in user research in 2018, and relationships with a pool of distance student users was established in 2019. however, a pool of other types of non-normative learners had not yet been established for either round of testing. another limitation of the study was that we primarily tested on campus servers, so we do not have data on rural or distance learner experiences with the textbook until the second round of testing. in addition, we used only a few devices, a windows 10 laptop for formal testing and an ipad students briefly viewed afterward. we also did not have an educational technologist as a partner throughout the process. results once testing was complete, the scholarly communications librarian and the user experience librarian analyzed the notes and identified areas of common concern and confusion among participants. all participants were familiar with online textbooks from other courses. participants cited cost as a major consideration when deciding between purchasing print or electronic texts. more than one participant said that electronic textbooks can be cheaper but can be more frustrating to use. participants had more experience viewing textbooks on laptops. the ability to download texts for reading on a phone was not always available due to publisher restrictions. content and navigation participants liked pictures and visuals to break up the blocks of text. however, one participant expressed a dislike for too many slideshows or other media. another in the first round of testing liked that there were not “too many” links that brought you out of the textbook, stating it was “annoying to split screen in order to see text plus activity/homework assignment.” in the second round of testing, one participant felt the lack of interactive content was best for the first-year students compared to videos and activities in textbooks for advanced courses. that participant also thought the simpler language of the text was more welcoming to first-year students. a information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 8 participant said an ipad would be better than a laptop for viewing this book, because scrolling was easier. several users did not find features such as bookmarked sections in the in-browser pdf viewers or adobe reader. participants who did not see or use the table of contents (toc) continually relied on scrolling through pages to locate content. only one participant, unprompted, used the ctrl+f shortcut to keyword search the text. a few other participants viewed the toc, then entered the desired page number in the top toolbar navigation field. most of them expected the code of conduct information in one of the tasks to be in the front matter. the emphasis on content reflects blakiston and mayden’s experience that without a content strategy, it becomes difficult to search and to demonstrate credibility, and it is a challenge to create a coherent, user-centered information architecture.51 all participants navigated to the toc several times to complete tasks, making it a relevant feature. in the second round of testing, one participant preferred the statements and questions at the beginning of the first chapter to learning objectives typically listed in textbooks. discovery and access participants took varied approaches to finding textbooks. one would get links from the professor via email or the syllabus. others would use the campus bookstore for purchases. one would use the student information system (raiderlink) to locate information about the textbook. potential access points to make the raiderready textbook discoverable included the institutional repository, the open textbook library, and the local library catalog. the open textbook library was ruled out mostly due to campus-specific adaptations, which were not more substantial for public use than the original college success. thinktech, the institutional repository, was the most viable option and allowed for permanent linking, which worked well with the access points student users mentioned. in the second round of testing, one participant searched for the textbook via the library catalog/discovery system, google search, and the raiderready department website. the course description on the department website listed an open textbook, but the user pointed out that it was not actually linked there. discussion user testing changed our actions during the project. interactions with students did not occur during any other stage of the adaptation process before the resource was adopted in the course. many insights from the testing were indicative of self-reported preferences such as requesting more visuals, preferring print for reading and exercises, and auditory screen reading. we also learned ways that cost impacted how students used textbooks. for example, when we followed up on a participant’s comment and asked if they liked to highlight books, the student responded that they try not to mark their books because they want to resell them. testing also helped us observe actual behaviors among similar users in a way oer toolkits and guidelines alone did not. we learned more about how oer fits into the culture of learning and resources at texas tech university and how that may differ from other institutions. for a visual representation of our workflow, we adapted billy meinke’s oer production workflow (targeted to creators) because it was an openly available, editable workflow with comprehensive discrete steps. similar to the corre framework adaptations, meinke’s workflow was adapted by others, including the southern alberta institute of technology (sait), lansing community college, and the university of houston, to fit their institutional contexts.52 our process did not include an external peer review process; instead review was done by the editors. priming and preproduction information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 9 phases in the workflow were relatively quick, occurring in the first two weeks. the bulk of time— about four weeks—was spent in the development phase. the quality assurance and publishing phases occurred for about two weeks, with most of the time spent on finalizing edits and formatting. the first round of user testing took about two hours total and redux (revisiting the prototype and implementing changes), along with the format finalization, took about two weeks. finalization for formatting and redux changes in the first iteration of the text involved pressbooks troubleshooting. the original timeline for the project was 30 days, but the actual time for the project was 60 days. the second round of user testing took about two hours total and occurred at the halfway point within a new 60-day deadline for an updated version of the textbook. we acknowledge that even though the actual time spent with users in the first round was limited to two hours, the process also required time for drafting recruitment emails, communicating with volunteers, scheduling testing, and debriefing after sessions. figure 3 shows our workflow diagram, including a new quality assurance phase (see fig. 4 for detail) based on our case study. it includes prototyping (content and format draft), user testing, and implementing user feedback on the oer prototype. figure

technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 10 figure 4. quality assurance phase with user testing. we addressed several suggestions participants made during testing to improve the textbook’s navigation functionality. we were able to address requests for a linked toc in the second round of testing. in the first round of testing, formatting was tailored to print pdf format because the editors wanted a print version to be available. we were able to create a linked toc in the digital pdf format, but not the printable pdf format. we were not aware that the toc could be changed based on available documentation in the first round of testing, but we were able to successfully troubleshoot this issue in the second round of tests. we were not able to do any customization on the search feature, which was built in. for customization, pressbooks allows styling through css files for three formats (pdf, web page, epub) separately. we customized them for look and feel. many of the requests were constrained by our working knowledge of and the technical limits of pressbooks, so we added a tips for pdf readers and printing section in the front matter of the textbook during the first round. it is important to note that although these were not major changes to the interface, they gave us insight for iterative changes. upon reflection, it would have been information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 11 preferable to involve someone with pressbooks developer experience at the outset. because we had not led a similar project before, nor worked with the software previously, we were more limited on the changes we could make as a result of testing than we expected. however, after this experience, we know what areas to test and are better prepared to effect actual changes. we made chapters available separately in the institutional repository to cut down on excessive scrolling, because scrolling through an entire textbook slowed students’ ability to study and quickly reference the text. also, the editors requested digital as well as print access to the textbook through the campus bookstore. the raiderready textbook was also added to the library’s local records in the catalog. we did not make a web version available through pressbooks. a web version was not a priority because of the institution-specific customization and because the editors did not request one. usage statistics from the repository between march 2018 and february 2019 peaked during midterms and at the end of semesters in which the class was taught. chapters 5, 6, 7, and 8 had the most downloads—the last chapters of the book, likely the chapters students were tested on for the final—with the majority of downloads (1,368) taking place during october 2018. this indicates that the option to download individual chapters appealed to students. accessibility testing the textbook with screen readers confirmed the need for an epub format of the text. hyde gives the following guidance for educators using pressbooks: “pdf accessibility is known to be somewhat limited, and in particular some files are not able to be interpreted by screen readers. the pdf conversion tool that pressbooks uses does support pdf tagging, which improves screen reader compatibility, but often the best solution is to offer web and e-book versions of a textbook as well as the pdf, so readers can find the format that best suits their needs.”53 for pdfs, issues included lack of alt tags, headings not set, and tables and images lacking tags. adding alt tags was planned early, after they were lost when uploading the wxr (wordpress extended rss) file—a wordpress export file in xml format—in pressbooks, and loss of the alt tags was confirmed during testing at the midpoint of the process. however, due to deadlines and pressbooks functionality, we were not able to address more of the tagging issues. epubs worked much better in tests with screen readers, apple devices, and e-readers. editors preferred that a pdf be used as the primary version and wanted an epub for screen readers upon request. our partners’ preference was likely based on the common use of pdfs but it did not comply with the principles of universal or inclusive design. regarding e-book accessibility, pressbooks documentation says, “ebook accessibility is somewhat dictated by the file format standards, which focus on font sizes and screen readers, and improvements are also being made with dynamic content. the international digital publishing forum has a checklist to prompt ebook creators on accessibility functions they can incorporate while creating their content.”54 we made a decision to include multiple formats to take multiple types of use into consideration. in the fir st round of changes, we included an epub alongside the pdf in the repository, so users with disabilities would not have to self-identify by making a request in order to gain access. upon learning more about inclusive design after the pilot, we realized we were treating users as a homogeneous group and segregating the more accessible version. in the second round, when we realized the epub was not available by separate chapters as was the pdf version, we then made it available by chapter as well. we recommend that evaluating oer according to the international digital publishing forum checklist be incorporated into the qa part of the workflow. information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 12 conclusion there is room for future research on iterative testing for oer and testing with more emphasis on mobile devices, testing with deeper investigation into microinteractions concerning accessibility, and testing in workflows that use other publishing platforms. as the creators of the floe project suggest, many more customizations can be made to points of user interactions if the software platform for adaptation is open source. future research may also examine regional and cultural influence on learning and interface preferences. one change that may support future adaptation projects at texas tech university would be modifying internal guidelines that take into consideration previous testing and local context. we also recommend keeping detailed documentation, particularly of steps for changes that are not included in existing guides on oer production. creating a memorandum of understanding with partners that clearly outlined responsibilities could have prevented some of the misunderstandings that occurred. for example, when stakeholders discussed producing print copies of the textbook, it wasn’t clear what the library’s role was. with a short timeline and more work involved than expected, the library was in a position of overpromising and underdelivering. it was apparent that the workflows themselves needed to be open and adaptable to support resources, communities, and processes in local contexts. it was important throughout the process to be aware of our partners’ priorities (e.g., instructional preferences, cost to students, departmental buy-in), because we had to balance these priorities with user feedback. we recommend having specific roles for content strategists, educational technologists, and developers in workflows during oer production. the work of creating workflows, assigning roles, and creating standards for oer content currently falls on librarians, instru ctional designers, and creators. as librarians seek the most sustainable workflows, it will be beneficial to emphasize investing in the quality assurance stages of oer production and evenly distributing responsibilities. this can be done through collaborative partnerships or by hiring additional positions. if other institutions were to scale the practices from our case study, ideally, librarians would take responsibility for adding roles or formalized work to the scope of either ux or oer departments so that it becomes normalized in oer workflows. we recommend working with editors to advocate for one textbook format that addresses a variety of learning needs. we plan to use these experiences, along with existing resources, to include inclusive and user -friendly recommendations in policies and guidelines for oer adaptation. conducting user testing did challenge assumptions about student use of oer by librarians and editing instructors. while we referred to toolkits, guidelines, and best practices, internal testing allowed us to make improvements to several specific microinteractions students encountered while using the text. it was very feasible to incorporate testing into the workflow. we were able to directly observe user information behavior from members of the community that the resource was intended to serve. information technology and libraries march 2021 user experience testing in the open textbook adaptation workflow | thomas, vardeman, and wu 13 appendix: usability

public libraries leading the way automating the diversity audit process rachel k. fischer information technology and libraries | september 2023 https://doi.org/10.5860/ital.v42i3.16925 rachel k. fischer (rfischer@ccslib.org) is the member services librarian at cooperative computer services, a public library consortium in illinois. © 2023. introduction i’ve frequently come across the buzzwords “mirrors and windows” at conference sessions or in articles on collection development and diversity audits. this striking metaphor refers to how books and other items in libraries are windows into other cultures and mirrors that reflect our own lives and experiences. if libraries’ collections and programs don’t properly reflect the diversity in america, and the whole world, the citizens of this country may not be able to have access to the materials that they need to gain appreciation for other cultures, genders, sexual orientations, or socio-economic statuses. minorities will continue to feel marginalized by not seeing themselves and their experiences reflected on them in the books they read and movies they watch. rudine sims bishop, the professor who first popularized the metaphor, stated, “when there are enough books available that can act as both mirrors and windows for all our children, they will see that we can celebrate both our differences and similarities, because together they are what makes us human.”1 to get to that point, the first step that libraries need to take is to analyze their collections, programs, toys, and policies by doing a diversity audit. the diversity audit can function as a steppingstone towards an improved collection development policy. what is a diversity audit? organizations have historically conducted audits of the diversity of their staff or their policies to avoid lawsuits and to promote systemic change. once a baseline has been established, the company is expected to make systemic changes to improve the policies and diversity of the staff. the concept of diversity audits is rather new to libraries. karen jensen first promoted the concept of a diversity audit of library collections in 2017 in articles published on school library journal’s blog, “teen librarian tool box.”2 since then, sarah voels, a librarian at the cedar rapids public library, published a book on the topic titled, auditing diversity in library collections.3 regarding library collections, a diversity audit is a methodology for analyzing the amount of diversity represented by the items in the library to establish a baseline as a benchmark. the audit consists of analyzing the diversity represented by subjects, fictional characters, authors, and illustrators of the items in the library collection. these statistics can be compared to population statistics to set goals for increasing the diversity of the collection. library programs and toys can also be analyzed. types of diversity that are typically analyzed include race or ethnicity, gender, sexual orientation, religion, and socio-economic status. there are two main manual methodologies that librarians can choose from. library staff and volunteers can review the titles being audited and record the data in spreadsheets. the statistics are tabulated in the spreadsheet. audits can be done of titles as they are purchased, randomly selected titles in a collection, or a whole collection. another option is called a “reverse audit.” this type of audit is accomplished by comparing award lists of diverse books, like the pura belpré award, to the collection and purchasing the titles that the library doesn’t own. mailto:rfischer@ccslib.org information technology and libraries september 2023 public libraries leading the way: automating the diversity audit process 2 fischer doing a manual audit of a full collection or a whole library can be very time-consuming. betsy bird, collection development manager at evanston public library, estimated that it took about 12 weeks to audit 18,508 titles in the adult fiction collection. if they were to attempt a manual audit of the whole library, it would take more than 6000 hours to audit 382,981 items. can you imagine the number of hours it would take to audit the 923,673 bibliographic records for physical items that could be audited in the entire shared database of the cooperative computer services (ccs) consortium, the consortium that evanston public library is a member of? to accomplish that, an automated process needed to be utilized. existing automated tools for diversity audits several vendors are already providing an automated diversity audit service. diverse bookfinder’s collection analysis tool (cat) is a free diversity audit tool for picture books. it is an award winning digital tool that’s financially supported by bates college and the institute of museum and library services. the director and founder of the website is associate dean of faculty and professor of psychology at bates college, dr. krista aronson. diverse bookfinder has collected and analyzed more than 3,000 picture books published since 2002 featuring black people, indigenous people, and people of color (bipoc). cat allows you to upload a list of isbns and titles. the file is compared to the diverse bookfinder (dbf) collection. cat produces a report that depicts the results of the analysis in graphs. the report explains how many titles match the dbf collection. the graphs describe the representation of ethnicities in the collection that matches the dbf collection and how they are represented, such as in a biography or folklore. although this service is free, its capabilities are limited to analyzing the titles that match the dbf collection. the two leading collection analysis tools, collectionhq and libraryiq, both include diversity audit reports. collectionhq is vendor neutral and owned by baker and taylor. it specializes in public libraries. libraryiq is also vendor neutral and can support all types of libraries and library consortia. both services can analyze the diversity of the collection. they each have a user -friendly interface and graphs that are easily understood. collectionhq is now offering customers of baker and taylor’s cataloging utility, btcat, the ability to add diversity, equity, and inclusion (dei) subject headings to bibliographic records as a bulk process. however, only libraryiq can suggest items to purchase to increase the diversity of the collection. in addition to baker and taylor, other major library vendors, such as ingram and midwest tape, include diversity audit services. both companies allow customers to purchase a one-time analysis of their collection(s). ingram’s report includes data for the whole collection compared to the public library average for comparison. a separate report includes suggestions of diverse titles to purchase to improve the diversity of the collection. midwest tape’s library collection diversity audit specifically audits video and audiobook collections. this service also produces a report analyzing the diversity of the collection and identifies areas to improve. however, the company utilizes a third-party to assist them in providing community demographic data to compare the library’s collection to local and national demographics. midwest tape’s service is also integrated with hoopla instant to help the customer fill in the gaps in diversity in the collection. cooperative computer services’ diversity audit tool not all libraries are able to spend money on a diversity audit service provided by vendors. however, libraries that already have a systems administrator who is well-versed in sql or other query languages that are used by their ils can create their own automated diversity audit tool. ccs has completed the creation of a diversity audit tool using tableau (see fig. 1). this tool information technology and libraries september 2023 public libraries leading the way: automating the diversity audit process 3 fischer analyzes the diversity of the physical items in the member libraries’ collections according to the subject headings of the bibliographic records and allows the libraries to benchmark against the whole consortium’s data or other libraries of similar demographics. the categories audited include women, bipoc, lgbtqia+, disabilities/neurodiversity, religious minorities, immigrants, and low income/economic welfare. like vendor provided diversity audits, the ccs diversity audit tool is limited to the data in the bibliographic record. only the subject of the titles can be audited, not the characteristics of characters or creators. the tool also includes a function to drill down into the data of narrower subcategories. in addition to the diversity audit dashboard, a collection development dashboard allows the librarians to identify popular titles on diverse topics that are owned by other libraries that they don’t own yet. this makes the selection and cataloging processes more efficient because the library already knows that these books will be checked out and the bibliographic record already exists. for an introduction to the tool, check out the video at: https://youtu.be/nonp2mgssuo. information about the sql query that is used to pull the data from the database and build the tables that tableau uses to analyze the data can be found at: https://reports.ccslib.org/divdoc. figure 1. ccs diversity audit tool conclusion auditing the diversity of a whole library collection is possible with the use of automated diversity audit tools. with a growing number of vendors offering diversity audit services that are integrated into their collection development and sales platforms, it is becoming increasingly easier for selectors to identify diverse titles to add to library collections. it, systems administrators, and even catalogers without selector duties, don’t have to sit on the sidelines. they can become active contributors by working within libraries and consortia to create their own diversity audit tools using tableau, google data studio, or even excel. although homegrown solutions have limitations, being able to analyze an entire library or consortium automatically can greatly improve the efficiency of the diversity audit process and supplement the manual methodology. https://youtu.be/nonp2mgssuo

public library melody friedenthal information technology and libraries | december 2021 https://doi.org/10.6017/ital.v40i4.14041 melody friedenthal (mfriedenthal@mywpl.org) is a public services librarian, worcester public library. © 2021. in june 2020, ital published my account of how the worcester public library (ma) came to offer a class in python programming and how that class was organized. although readers may have read the article in the middle of our covid-year, i wrote it mostly in early january 2020, before libraries across the country closed in an effort to protect staff and patrons from the disease. from spring 2020 through april 2021, i taught intro to coding: python for beginners five more times. but, of course, these classes were not face-to-face. like virtually all other library, musical, political, religious, and cultural programming across the world, our python course was taught virtually. the public services team has one professional zoom account, which my colleagues and i share. how did going remote affect this class? it depends on whether your perspective is that of a student or that of the instructor. many of us have read how difficult it’s been for teachers to effectively reach their elementarythrough-collage-age students. i’ve had many of the same challenges, but since nearly all my students are adults and they all chose to take this class, i don’t need to grapple with fidgety kids or recess. on the other hand, there were few distractions in our computer lab, while covid-time students have to grapple with pets, children squabbling, or noise from a tv. i was teaching from my home office. at the library i have one monitor but at home i have two, which makes it easier for me to spread out my assorted documents. to “protect” my students from seeing my messy house, i used a virtual background, one chosen not to distract. however, the software which determines the borders of a human presenter isn’t perfect and there is sometimes a halo behind my head of the things behind me; this may be distracting itself. prior to covid, since we had twelve seats in the computer lab, we limited registration to fourteen, allowing for some no-shows (and we have two spare laptops, in case everyone showed up). a week prior to session one i would email the registrants, asking them to confirm their continued interest. if a student didn’t confirm, i’d give their seat to someone on the waitlist. while i was not prepared to make my class a mooc (massive open online courses) because i individually review homework and give lots of feedback, we did increase maximum registration to fifteen since the number of seats in the computer lab was no longer a limiting factor. and, as before, i ask for confirmation via email, but i also include in that email two links and an attached word doc. the document is an excerpt from cory doctorow’s novel little brother on the joys of coding. information technology and libraries december 2021 how covid affected our python class | friedenthal 2 the first embedded link leads to the free version of zoom. the second link is to the thonny website (https://thonny.org). thonny is a free ide (integrated development environment) where students can write and execute python code. we used thonny when i taught face-to-face, but the lab computers all had thonny installed, and were ready for students to use. now, i have to depend on the ability of students to download the software to their own computers. i ask students to do the two downloads ahead of session one. which brings us to two problems: the class was no longer accessible to students who live in a household without a computer and internet service. and, as i found out with one prospective student, it’s not accessible to patrons who don’t have administrative rights to their computer; that is, the ability to download new software. when a patron confirms their interest, i email them the course manual. it now contains about 93 pages. i told students they might choose to print it but doing so is up to individual preference. the advantage of having a digital copy is that students can search for keywords easily. the disadvantage is that the cost of printing the manual is shifted to the student and may be prohibitive for some. in session one, i acknowledged that it’s difficult to learn technical material via zoom, and i encouraged everyone to ask questions during class and to email me if they are stymied while working on the homework. i reiterated that invitation during every session. while teaching, i bounce back-and-forth between screen-sharing my thonny window and the manual, while trying to keep an eye on the little zoom windows showing my students. some students cannot or choose not to turn on their video. this is a problem for me, since i can’t readily determine who’s asking a question. moreover, it is helpful to associate a face with a name. and since i give out a certificate of completion to each student who does the homework and attends all sessions, i want to make sure the student is actually taking part. i’ve had students who sign in, leave their camera off, and then apparently leave (i call on students by name and sometimes the no-video ones never respond). offering the class online has advantages in snowy worcester. students can tune in from the comfort of their own homes, avoid the slick roads, bypassing paying for parking at the municipal lot next to our building or for a bus to downtown, or the discomfort of walking in a dark citycenter in the evening. another plus: as program organizers and program participants have discovered, with videoconferencing we are no longer limited geographically. i had registrants who live in pennsylvania and georgia. as always, students range from total beginners to experienced programmers-of-other-languages. i’ve thought about how i can give extra time to the former while not boring the latter. one thing i’ve done is to make some assignments optional and say, “if you want an extra challenge, give this a try….” i’ve slowed the class down a bit, leaving more time for coding during each session. if a student has difficulties, i invited them to share their screen. this pedagogical technique actually works better information technology and libraries december 2021 how covid affected our python class | friedenthal 3 via zoom than in-person, because we could all see that screen equally well. in the computer lab, only the student who sat at the same (2-person) desk could easily see what the other person had coded. another thing i’ve done is to ratchet down the formality of the class: i am chattier and demo fun games i’ve written, e.g., hangman, tic-tac-toe, rock-paper-scissors, and you sunk my battleship, for inspiration. i experimented with using the built-in zoom whiteboard but that wasn’t satisfactory, so i wrote supplementary notes as comments in thonny. parents were fearful their kids were not being intellectually challenged when schools were closed due to the pandemic, so maybe i shouldn’t have been surprised that the april 2021 class contained seven children. there would have been an eighth, but when i realized one registrant was just seven years old, i told his mother that, while she was the best judge of her son’s abilities, i discouraged him from taking the class. she decided to take it herself. figure 1. a word-cloud of our fall 2020 project outcome evaluations (includes other digital learning programs). at our sixth and final session i traditionally execute a program which draws colorful graphics, rather like spirograph. students were able to see each curve being drawn in a new window launched by the ide. but this window doesn’t exist until i executed the program. while we were information technology and libraries december 2021 how covid affected our python class | friedenthal 4 using zoom, when i attempted to share my screen, the students missed the first graphics, no matter how fast i was at screen-sharing. i made the execution “sleep” for a few seconds to give me time to switch screens before the graphics were drawn. a larger percentage of students earned the certificate of completion during the virtual classes than on average in the in-person pre-covid classes, perhaps 75% vs. 40%. for the in-person classes our communications officer printed the certificates on heavy paper adorned with the wpl logo; i signed each and handed them out during the final session. for our virtual classes, the certificates were digitally signed and then emailed; students could print them if they chose. this follow-up is being written during october 2021, and with a substantial percentage of massachusetts residents vaccinated for covid, the worcester public library is now back to offering many programs in-person, including python. the city of worcester requires mask use in all municipal buildings, and while some patrons don’t cooperate, i’ve told my students that anyone not wearing a mask properly will be asked to leave the computer lab. with so many people out of work due to the economic devastation wrought by covid, we were gratified to be able to offer a class that teaches in-demand skills, especially ones that can be applied in a work-from-home environment. harnessing the power of orcam public libraries leading the way harnessing the power of orcam mary howard information technology and libraries | september 2020 https://doi.org/10.6017/ital.v39i3.12637 mary howard (mhoward@sccl.lib.mi.us) is reference librarian library for assistive media and talking books (lamtb) at the st. clair county library, port huron, michigan. © 2020. library for assistive media and talking books services (lamtb) are located at the main branch for the st. clair county’s library system. lamtb facilitates resources and technologies for residents of all ages who have visual, physical, and/or reading limitations that prevent them from using traditional print materials. operating out of port huron, michigan, we encounter many instances where we need to provide assistance above and beyond what a basic library may offer. we host talking book services which provide free players, cassettes, braille titles, and downloads to users who are vision or mobility impaired. we also have a large and stationary kurtzweil reading machine that converts print to speech, video-enhanced magnifiers, large print books. we also provide home delivery service for patrons who are unable to travel to branches. the library has been searching for a more technology-forward focus for our patrons. the state’s talking books center in lansing set up an educational meeting at the library of michigan in 2018 to see a live demonstration of the orcam my eye reader. this was the innovation we were seeking and i was thoroughly impressed with the compact and powerful design of the reader, the ease of use, and the stunningly accurate feedback provided by this ai reading assistive device. users are able to read with minimal setup and total control. orcam readers are lightweight, easily maneuverable assistive technology devices for users who are blind, visually impaired, or have a reading disability, including children, adults and the elderly. the device automatically reads any printed text: newspapers, money, books, menus, labels on consumer products, text on screens, books, or smartphones, etc. the orcam reader will repeat back any text immediately and is fit for all ages and abilities. orcam works with english, spanish, and french languages and can identify money and other business and household items. it can be placed near either the left or right ear. users can easily adjust the volume and speed of the read text. it can be to either the left or right temple on your glasses using a magnetic docking device. having a diverse group of users with different needs use the reader as they like is one of the more impressive offerings. changing most settings is normally facilitated with just a finger swipe on the orcam device. the mission of orcam is to develop a "portable, wearable visual system for blind and visually impaired persons, via the use of artificial computer intelligence and augmented reality” by offering these devices to our sight, mobility, or otherwise impaired patrons we open up the world of literacy, discovery and education. some of our users are not able to read in any other fashion and the orcam provides a much-needed boost to their learning profile. we secured a grant from the institute of museum and library services (imls) for the purchase of the readers (cfda 45.310). we also worked with orcam to get lower pricing for these units. normally they retail for $3,500 but we were able to move this to the lower price point of $3,000. we also were awarded a $22,106 improving access to information grant from the library of michigan to fund the entire purchase. without this funding stream we would not have been able to secure the orcam. however, if you have veterans in your service area please contact the company since there is availability for va health coverage for low vision or legally blind veterans who may information technology and libraries september 2020 harnessing the power of orcam | howard 2 qualify to receive an orcam device, fully paid for by the va. please visit https://orcam.com/en/veterans for more information. figure 1. close-up of the orcam device. the grant was initially set to run from september 2019 to september 2020. we purchased six orcam readers for our library users, and they were planned to be rotated among our twelve branches throughout this grant cycle. however, due to the pandemic and out of safety concerns for staff and visitors, our library was closed from march 23 to june 15 and we were only able to offer it to the public at six branches. as of july 14, 2020, we are projecting that we may open to the public in september, but covid-19 issues could halt that. we have had to make arrangements with the grantor to extend the period for the usage of the orcam from september to december. this will make up for some of the lost time and open a path for the other six libraries to have their turn offering the orcam to their patrons. the interesting aspect of this is we now have to take our technology profile even further by offering remote training to prospective orcam users. thankfully, the design and rugged housing for the reader makes it easy to clean and maintain but the social distancing can prove to be intrusive for training. to set up a user you need to be within a foot or two of them and being very close in order to get them used to how the orcam reads. there is a lot of directing involved and close contact with the user and instructor. we will use a work around of providing distance instruction including in-person and remote training. orcam also has a vast array of instructional videos that we will have cued up for users. we have had over 150 https://orcam.com/en/veterans information technology and libraries september 2020 harnessing the power of orcam | howard 3 residents attend presentations, demonstrations, and talks on the orcam. i anticipate that this number will not be achieved for the second round; however, we may be more successful in our online presence since we can add the instruction to our youtube page, offer segments on facebook and other social media and provide film clips for our webpage. the situation has been difficult, but it has opened up lamtb services to think about how we should be working to provide better and more remote service to our users. since we cover over 800 square miles in the county, becoming more adaptable to servicing our patrons has become a paramount area of work for the library. the orcam will bring about a new way of remote training to our patrons, which will bring about more awareness of the reader and how it can be beneficial to users. the st. clair county library system would like to thank the institute of museum and library services for supporting this program. the views, findings, conclusions or recommendations expressed in this article do not necessarily represent those of the institute of museum and library services. lib-s-mocs-kmc364-20141005043630 63 technical communications announcements with this issue we begin the process of shifting the emphasis and content of technical communicatiom. some of the newsletter features of technical communicatiom will be dropped due to the fact that as a quarterly publication it cannot be satisfactorily used to disseminate certain kinds of temporal information (e.g., short lead-time announcements, notification of institutes, seminars, meetings, etc.) . instead, brief articles, letters, or comments on lola articles, and pertinent information about technical developments will hopefully assume a larger percentage of the allotted pages for technical communications. the isad editorial board, in approving these changes, voiced the opinion that technical communications would be much more useful as a result. concise technical communications and information notes featuring any aspect of the application of computers, systems analysis, or other technological developments (hardware, software, or techniques) pertinent to libraries are solicited. the design is also meant to provide a forum for the more rapid dissemination of information that will sometimes serve as the basis for the longer, more detailed articles which are published in lola. thus, the salient findings in a study, or the important developments taking place in a project or ongoing operation can be made known long before they might otherwise be brought out in a formal presentation. these changes should become evident by the march 1974 issue, and to insure that this type of material does begin making its appearance, please send your letters notes and technical communications , , . to the editor of technical commumcations.

(extracted from the american city, march 1973) peacesat (pan pacific education and communication experiments by satellite) populations in the pacific basin are often small in size and divided by great distances, making it impossible for many to sustain adequate levels of educ ation, health care, and technically based services. inadequate communications constitute a principal barrier to development. 64 journal of library automation vol. 6/1 march 1973 pan pacific education and communication experiments by satellite (peacesat) is a demonstration project in which selected educational and medical institutions in the pacific basin are linked by means of communication satellite relay. voice and facsimile are sent and received by each location in the system. slow-scan television and teletype will be used at some locations. the peacesat project is not a permanent service. it is a pilot demonstration to provide experience in the use of long distance transmission on which to base the design of future telecommunication services. its objectives are to increase the quality of education in the pacific by facilitating sharing of scarce, costly resources; to improve professional services in sparsely populated areas through telecommunication support; and, generally, to assist in applying the potential of satellite technology to the solution of domestic social problems and peaceful world development. the system is unique in the world. the satellite used is the ats-1 operated by the national aeronautics and space administration. only established and tested technology is used in the system. the costs to participants are small. exchanges conducted through the peacesat facilities involve two-way communication, two or more locations interconnected at one time, and often many users at each location engaged in dialogue with users at other terminals. the format and content are determined by the users. the idea of using satellite relay to facilitate communication for educational, health, and community services in remote areas of the pacific basin was proposed in 1969 to the national aeronautics and space administration by dr. john bystrom, professor of communication at the manoa campus of the u diversity of hawaii. a start on the project was made in december 1970 when president harlan cleveland approved a grant from the u diversity's innovative program. in february 1971, nasa approval for use of the ats-1 was granted. dr. paul yuen, professor of electrical engineering, and icatashi nose, associate professor of physics, had two prototype ground terminals available when the federal communications commission approved licenses for the experiment. in phase i of the project, beginning april 1971, ground terminals constructed at the university were successfully testoperated and utilized between hawaii community college in hila and the manoa campus of the university of hawaii. the hawaii state legislature emphasized its support of the project by appropriating $75,000 in april 1971. the international network began in january 1972 with terminals at wellington polytechnic in wellington, new zealand, and the university of the south pacific in suva, fiji, joining the system. additional terminals have been established at maui community college, kahului, maui ( hawaii); papua new guinea institute of technology, lae, png; the university of south pacific centre, nuku'alofa, tonga ; and the department of education, pago pago, american samoa. operating terminals are being established at saipan and truk in the trust territory of the pacific islands. the project is administered by the university of hawaii with the assistance of the governor's committee on pan pacific educational communications, appointed by governor john burns and headed by uh president harlan cleveland. a faculty advisory committee assists development at the university of hawaii. recommendations for long range planning in medical research are provided by a medical communications study advisory committee project director is dr. john bystrom, assisted by james mcmahon, system coordinator. technical design and development is under the direction of dr. paul yuen. key to the system is a small inexpensive ground terminal designed and constructed at the university by katashi nose. each of the educational institutions which have terminals have their own autonomous staff and organization which operate the equipment and develop educational uses of the system. management of the peacesat terminal on the manoa campus is under carol misko, terminal manager. during its relatively short existence, the peacesat system has been utilized in a wide variety of educational and scientific programs. the east-west center used a receiving station on the ocean liner president wilson to conduct orientation sessions with its arriving grantees. hamilton library on the manoa campus has demonstrated exchange of materials with other locations via peacesat. doctors of the pacific research section of the national institute of health consult with doctors at the bethesda, maryland, national library of medicine. the hawaii cooperative extension service has used the system to conduct seminars with specialists from new zealand, fiji, tonga, and hawaii locations. faculty and students at the various campuses of the system have utilized the communication channels made available by peacesat. a few among the many disciplines they represent are political science, english, spanish, education, indonesian languages, physics, oceanography, computer science, journalism, urban planning, and speech-communication. it was the peacesat system which carried the world's first regularly scheduled class of instruction via satellite. within the pacific basin keen interest has been shown in the development of this project, as evidenced by discussion of peacesat at meetings of the south pacific forum and the south pacific commission. the peacesat network recently provided the means for south pacific poets to exchange their works with one another. amonv those joining in the wellreceived poetry series was the poet laureate of tonga. in april 1972 the national library of medicine awarded the university of hawaii a contract for a study of medical networking in the pacific, incorporating demonstrations of library and professional exchanges. hours of operation for the network are currently 9:00-10:00 a.m. and 4:306:00 p.m., monday through friday {honolulu time). the manoa exchange center is located in george hall (212) on the technical communications 65 campus of the university of hawaii. peacesat project, program in communication, university of hawaii, honolulu, hi 96822. phones: ( 808) 948-8848, ( 808) 948-8771, rca telex #723597. tomorrow's library: spools of tape libraries with ranks of musty tomes and files of catalog cards may be difficult to flnd in the future. books probably will be in museums; libraries will be on spools of computer tape. library users might push a button for a no-deposit, no-return paperback printout, instead of standing in line for a hardback from the stacks. movement in these directions has already begun at the university of georgia where a staff of 110 and $9 million of computer hardware provide the following type of service: a professor sits before a crt and types out the chemical names of ddt on the keyboard. almost immediately, the television screen above the keyboard displays a list of 176 scientific references to ddt. this information is the result of an electronic search of about 40,000 issues of chemical abstracts, a title compilation on computer tape of all published scientifl.c papers in chemistry. similar abstracts are available in other scientific fields, and three large foundation grants will enlarge these holdings to include literature in engineering, education, and the humanities. the information retrieval system allows a user to "browse as he would in a li· brary." but the browsing is done through one of 37 remote terminals. the number of remote terminals is expected to more than quadruple in future years, giving a total of some 200 individual outlets. (extracted from couege management) library projects and programs microfiche catalog by tulsa city-county library the tulsa city-county library computer output microfiche catalog was published in early march, according to ruth blake, director of technical services, tulsa city-county library. the catalog is in 66 journal of library automation vol. 6/1 march 1973 register-index format. the register, arranged by number, contains full bibliographic information for each title. adult and juvenile indexes contain brief bibliographic entries, location information, and a reference to the register number of each title. both indexes are in dictionary form, with authors, titles, and subjects in a single alphabet. minnesota bio-medical mini-computer project the university of minnesota bio-medical library has received a $361,729 three-year grant from the national library of medicine to provide support during the development of a low cost, stand alone, library dedicated computer system. the system will employ on-line terminals for data entry and file query functions, and will be based on an integrated system design of a processing system which would be suitable for use in other libraries of a similar size. the premise of the development is that an integrated acquisitions, accounting, in-process control system for all library materials coupled with an on-line catalog/ circulation control system can be operationally affordable by a library or system of libraries in the 200,000 volume class using its own computer system. a digital equipment corp. pdp 11/ 40 system has been selected. the cpu features 16k core, 16 bit word, power fail/ automatic restart, programmable real time clock, extended instruction set, and memory management option which permits access to 124k of memory. a dec writer data terminal will be used as console and initial terminal on the system. two 9 channel 800 bpi tape drives and one 40 million character moving head disk pack drive comprise the system's initial mass storage. a 132 column, 96 character set line printer completes the initial hardware configuration. before the system is installed, suitable crt type terminals and communications interfaces will be chosen. six of these terminals will be required when the system is fully operational. memory expansion in the cpu and additional mass storage may be acquired depending upon needs, although the design efforts will be to minimize the amount of core required for the system and most efficiently use the mass storage available. one of the problems of using a minicomputer system to service an interactive on-line library system is a lack of a suitable operating system which can require minimal residency in core, yet contain only the functions needed on a library system. current timesharing operating systems provide some parts of a system, such as device handlers, but require too great allocation of core, or programming in a compiler level language such as basic. this approach has been deemed unsatisfactory if system costs for hardware are to be kept reasonable. during the development period a pdp 11140 dos operating system will be used to assist in writing a hybrid operating system and utilities using the pdp 11/40 assembler language. also under development will be the file design, the system common modules, and system dictionary. these elements of the system will be required to then design and program the individual system applications. since the grant does not provide any support for data conversion, the circulation application will be developed and installed for the reserve materials. these only number a few thousand and involve short loan periods and other complexities which will provide an excellent test of a circulation control system for general library-wide use. other application systems, such as acquisitions and serials already are computer supported and therefore have existing machine-readable data files. the project staff includes glenn brudvig, director of the bio-medical library as principal investigator; audrey n. grosch of the university libraries systems division as project director and the following systems specialists: bob denney, carl sandberg, eugene lourey, and don norris. pertinent recent publications nationwi.de survey of library automation -phase i. the california state university and colleges has published the final report of phase i of its nationwide survey of library automation. this comprehensive survey performed for the chancellor's office-library systems project by inforonics, inc. covers over twenty-five library automation projects in the united states and canada. those interested in obtaining a copy should write, enclosing a check in the amount of $5.00 (californians remember the 6 percent tax) to chancellor's office;

submit etds into proquest: a case study of a lesser-known approach communications using the harvesting method to submit etds into proquest a case study of a lesser-known approach marielle veve information technology and libraries | september 2020 https://doi.org/10.6017/ital.v39i3.12197 marielle veve (m.veve@unf.edu) is metadata librarian, university of north florida. © 2020. abstract the following case study describes an academic library’s recent experience implementing the harvesting method to submit electronic theses and dissertations (etds) into the proquest dissertations & theses global database (pqdt). in this lesser-known approach, etds are deposited first in the institutional repository (ir), where they get processed, to be later harvested for free by proquest through the ir’s open archives initiative (oai) feed. the method provides a series of advantages over some of the alternative methods, including students’ choice to opt-in or out from proquest, better control over the embargo restrictions, and more customization power without having to rely on overly complicated workflows. institutions interested in adopting a simple, automated, post-ir method to submit etds into proquest, while keeping the local workflow, should benefit from this method. introduction the university of north florida (unf) is a midsize public institution established in 1972, with the first theses and dissertations (tds) submitted in 1974. since then, copies have been deposited in the library, where bibliographic records are created and entered in the library catalog and the online computer library center (oclc). during the period of 1999 to 2012, some tds were also deposited in proquest by the graduate school on behalf of students who decided to. this practice, however, was discontinued in the summer of 2012, when the institutional repository, digital commons, was established and submission to it became mandatory. five years later, in the summer of 2017, interest in getting unf tds hosted in proquest resurfaced. this renewed interest grew out from a desire of some faculty and graduate students to see the institution’s electronic theses and dissertations (etds) posted there, in addition to a recent library subscription to the proquest dissertations & theses global database (pqdt). a month later, conversations between the library and graduate school began on the possibility of resuming hosting unf etds in proquest. consensus was reached that the pqdt database would be a good exposure point for our etds, in addition to the institutional repository (ir), yet some concerns were raised. one of the concerns was cost of the service and who would be paying for it. neither the library nor the graduate school had allocated funds for this. the next concern was the possibility of proquest imposing restrictions that could prevent students, or the university, from posting etds in other places. it was important to make sure there were no such restrictions. another concern was expressed over students entering embargo dates in proquest that do not match the embargo dates selected for the ir. this is a common problem encountered by other libraries.1 for that reason, we wanted to keep the local workflow. the last concern expressed during the conversations was preserving students’ right to opt-in or out from distributing their theses in proquest. this is something both the graduate school and library have been adamant mailto:m.veve@unf.edu information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 2 about. in higher education, requiring students to submit to proquest is a controversial issue which has raised ethical concerns and has been highly debated over the years.2 once conversations between the library and graduate school were held and concerns were gathered, the library moved ahead to investigate the available options to submit etds into proquest. literature review currently, there are three options to submit etds into proquest: (1) submission through the proquest etd administrator tool, (2) submission via file transfer protocol (ftp), and (3) submission through harvests performed by proquest.3 proquest etd administrator submission option in this option, a proprietary submission tool called proquest etd administrator is used by students, or assigned administrators, to upload etds into proquest. inside the tool, a fixed metadata form is completed with information on the degree, subject terms are selected from a proprietary list, and keywords are provided. the whole administrative and review process gets done inside the tool. afterwards, zip packages with the etds and proquest’s extensible markup language (xml) files are sent to the institution via ftp transfers, or through direct deposits to the ir using the simple web-service offering repository deposit (sword) protocol. the etd administrator submission method presents several shortcomings. first, the proquest xml metadata that is returned to the institutions must be transformed into ir metadata for ingest in the ir, a process that can be long and labor intensive.4 second, the subject terms supplied in the returned files come from a proprietary list of categories maintained by proquest, which does not match the library of congress subject headings (lcsh) used by libraries.5 third, control over the metadata provided is lost because the metadata form cannot be altered, plus customizations to other parts of the system can be difficult to integrate. 6 fourth, there have been issues with students indicating different embargo periods in the proquest and ir publishing options, with instances of students choosing to embargo etds in the ir, while not in proquest.7 lastly, this method does not allow students’ choice, unless the etds are submitted separately in two systems in a process that can be burdensome. ultimately, for these reasons, we found the etd administrator not a suitable option for our institution. ftp submission option in this option, an administrator sends zip packages with the institution’s etd files and proquest xml metadata to proquest via ftp.8 at the time of this investigation, there was a $25 charge per etd submitted through this method.9 we did not want to pursue this option because of the charge and the tedious metadata transformations that would be needed between ir and proquest xml schemas. another way to go around this would have been to submit the etds through the vireo application. vireo is an open source, etd management system used by libraries to freely submit etds into proquest via ftp.10 this alternative, however, was not an option for us as our ir, digital commons, does not support the vireo application. harvesting submission option this is the latest method available to submit etds into proquest. in this option, etds are submitted first into an ir, or other internal system, where they get processed to be later harvested by proquest through the ir’s existing open archives initiative (oai) feed.11 at the time of this writing, we were not able to find a single study that documents the use of this method. this option information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 3 looked appealing and worth pursuing as it met most of our desired criteria. first, with this option, students’ choice would not be compromised as etds would be submitted to proquest after being posted in the ir. second, because the etd administrator would not be used, issues with conflicting embargo dates and unalterable metadata forms would be avoided. in addition, the local workflow would be retained, thus eliminating the need for tedious metadata transformations between proquest and ir schemas. from the available options, this one seemed the most feasible solution for our institution. implementation of the harvesting method at unf after research on the different submittal options was performed, the library approached proquest to express interest in depositing our future etds into their system by using a post-ir option. in the first communications, proquest suggested we use the etd administrator to submit etds because is the most commonly used method. when we expressed interest in the harvesting option, they said “we have not been harvesting from bepress sites” (the company that makes digital commons) and suggested we use the ftp option instead.12 ten months later, they clarified the harvests could be performed from bepress sites and that the option is free, with the only requirement of a non-exclusive agreement between the university and proquest. the news appeased both the library’s and the graduate school’s previous concerns, as we would be able to adopt a free method that would not compromise on students’ choice nor restrict students from posting in other places, while keeping the local workflow. after agreement on the submittal method was established, planning and testing of the harvesting method began. the library worked with proquest and bepress to customize the harvesting process while the university’s office of the general counsel worked with proquest on the negotiation process. negotiation process before proquest could harvest unf etds, two legal documents needed to be in place. the first document was the theses and dissertations distribution agreement, which specifies the conditions under which etds can be obtained, reproduced, and disseminated by proquest. the document had to be signed by the unf’s board of trustees and proquest. the agreement stipulated the following conditions: • the agreement must be non-exclusive. • the university must make the full-text uniform resource locators (urls) and abstracts of etds available to proquest. • proquest must harvest the etds from the university’s ir. • the university and students have the option to elect not to submit individual works or to withdraw them. • no fees are due from the university or students for the service. • proquest must include the etds in the pqdt database. the second document that needed to be in place was the theses and dissertations availability agreement, which grants the university the non-exclusive right to reproduce and distribute the etds. this agreement between students and unf specifies the places where etds can be hosted and the embargo restrictions, if any. unf already has been using this document as part of its etd workflow, but the document needed to be modified to include the additional option to submit information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 4 etds into proquest. beginning with the spring 2019 semester, the revised version of the agreement provided students with two hosting alternatives: posting in the ir only or in the ir and proquest. local steps performed before the harvesting the workflow begins when students upload their etds and supplemental files (certificate of approval and availability agreements) directly into the digital commons ir. in there, students complete a metadata template with information on the degree and keywords related to the thesis are provided. after this, the graduate school reviews the submitted etds and approves them inside the ir platform. next, the library digital projects’ staff downloads the native pdf files of etds, processes them, and creates public and archival versions for each etd. availability agreements are reviewed to determine which students chose to embargo their etds and which ones chose to host them in proquest, in addition to the ir. if students choose to embargo their etds, the embargo dates are entered in the metadata template. if students choose to publish their etds in proquest, a “proquest: yes” option is checked in their metadata template, while students who choose not to host in proquest would get a “proquest: no” in their template. (the proquest field is a new administrative field that was added to the etd metadata template, starting with the spring 2019 semester, to assist with the harvesting process. it was designed to alert proquest of the etds that were authorized for harvesting. more detail on its functionality will be provided in the next section.) the reason library staff enters the proquest and embargo fields on behalf of students is to avoid having students enter incorrect data on the template. following this review, the metadata librarian assigns library of congress subject headings to each etd and creates authority files for the authors. these are also entered in the metadata template. afterwards, the etds get posted in the digital commons’ public display, with the fulltext pdf files available only for the non-embargoed etds. information that appears in the public display of digital commons will also appear immediately in the oai feed for harvesting. at this point, two separate processes take place: 1. metadata librarian harvests the etds’ metadata from the oai feed and converts it into marc records that are sent to oclc, with the ir’s url attached. the workflow is described at https://journal.code4lib.org/articles/11676. 2. on the seventh of each month, proquest harvests the full-text pdf files, with some metadata, of the non-embargoed etds that were authorized for harvesting from the oai feed. harvesting process (customized for our institution) to perform the harvests, proquest creates a customized robot for each institution that crawls oaipmh compliant repositories to harvest metadata and full-text pdf files of etds.13 the robot performs a date-limited oai request to pull everything that has been published or edited in an ir’s publication set during a specific timeframe. information to formulate the date limited request is provided to proquest by the institution for the first harvest only, subsequently, the process gets done automatically by the robot. the request contains the following elements: information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 5 • base url of the oai repository • publication set • metadata prefix or type of metadata • date range of titles to be harvested in the particular case of our institution, we needed to customize the robot to limit the harvests to authorized etds only. to achieve this, we worked with bepress to add a new, hidden field at the bottom of our digital commons’ etd metadata template. the field, called proquest, consisted of a dropdown menu with 2 alternatives: “proquest yes” or “proquest no” (see figure 1). the field was mapped to an element in the oai feed that displays the value of “proquest: yes” or “proquest: no,” thus alerting the robot of the etds that were authorized for harvesting and the ones that were not. the element used to map the proquest field in the oai feed is the <dc:description.note>, which is a qualified dublin core (qdc) element (figure 2). for that reason, the robot needs to perform the harvests from the qdc oai feed in order to see this field. figure 1. display of the proquest field’s dropdown menu in the metadata template figure 2. display of the proquest field in the qdc oai feed after the etds authorized for harvesting have been identified with help from the “proquest: yes” field, the robot narrows down the ones that can be harvested at the present moment by using the <dc:date.available> element. this element, as the name implies, provides the date when the full text file of an etd becomes available. it also displays in the qdc oai feed (see figure 3). if the date is on or before the monthly harvest day, the etd is currently available for harvesting. if the date is in the future, the robot identifies that etd as embargoed and adds its title to a log of embargoed etds with some basic metadata (including the etd’s author and the last time it was checked). the log of embargoed etds is then pulled out in the future to identify the etds that come out of embargo so the robot can retrieve them. figure 3. display of the <dc:date.available> element in the qdc oai feed information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 6 after the etds that are currently available for harvesting have been identified (because they have the “proquest: yes” field and a present or past availability date), the robot performs a harvest of their full-text pdf files by using the third <dc:identifier> element, which displays at the bottom of records in the oai feed (figure 4). the third <dc:identifier> element contains a url with direct access to the complete pdf file of etds that are currently not embargoed. etds that are currently on embargo contain a url that redirects the user to a webpage with the message: “the full-text of this etd is currently under embargo. it will be available for download on [future date]” (see figure 5). figure 4. display of the third <dc:identifier> element at the bottom of records in the qdc oai feed figure 5. message that displays in the url of embargoed etds once the metadata and full-text pdf files of authorized, non-embargoed etds have been obtained by the robot, they get queued for processing by the proquest editorial team, who then assigns them international standard book numbers (isbns) and proquest’s proprietary terms. it takes an average of four to nine weeks for the etds to display in the pqdt database after been harvested. records in the pqdt come with the institutional repository’s original cover page and a copyright statement that leaves copyright to the author. afterwards, the process gets repeated once a month. this frequency can be set to quarterly or semi-annually if desired. information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 7 additional points on the harvesting method handling of etds that come out of embargo. when the embargo period of an etd expires, the full-text pdf of it becomes automatically available in the ir’s webpage, and consequently, in the third <dc:identifier> element that displays in the oai record. each month, when the robot prepares to crawl the oai feed, it will first check for the titles in the log of embargoed etds to determine if any of them have become fully available through the third <dc:identifier> element. the ones that become available are then pulled by the robot through this element. handling of metadata edits performed after the etds have been harvested and published in pqdt. edits performed to metadata of etds will trigger a change of date in the <datestamp> element that displays in the oai records. this change of date will alert the robot of an update that took place in a record, which is then manually edited or re-harvested, depending on the type of update that took place. sending marc records to oclc. as part of the harvesting process, proquest provides free marc records for the etds hosted in their pqdt database. these can be delivered to oclc on behalf of the institution on an irregular basis. records are machine-generated “k” level and come with urls that link to the pqdt database and with proquest’s proprietary subject terms. we requested to be excluded from these deliveries and continue our local practice of sending marc records to oclc with lcsh, authority file headings, and the ir’s urls. notifications of harvests performed by proquest and imports to the pqdt database. when harvests or imports to the pqdt have been performed by proquest, institutions do not get automatically notified. still, they can request to receive scheduled monthly reports of the titles that have been added to the pqdt. unf requested to receive these monthly reports. usage statistics of etds hosted in pqdt. usage statistics of an institution’s etds hosted in the pqdt can be retrieved from a tool called dissertation dashboard. this tool is available to the institution’s etd administrators and provides the number of times some aspect of an etd (e.g., citations, abstract viewings, page previews, and downloads) has been accessed through the pqdt database. royalty payments to authors. students who submit etds through this method are also eligible to receive royalties from proquest. obstacles faced during the planning phase, we encountered some obstacles that hindered progress on the implementation. these were: • amount of time it took to get the ball rolling. initially, we were misled by the assumption we would not be able to use the harvesting method to submit etds into proquest because we were bepress users, as we were originally told, but that ended up not being the case. ten months later, we were notified by the same source that the harvesting option for bepress sites would be possible and doable by proquest. these were ten months that delayed the implementation process. information technology and libraries september 2020 using the harvesting method to submit etds into proquest | veve 8 • amount of time it took to get the paperwork finalized and signed before the harvesting. from the moment first contact was initiated with proquest, to the moment the last agreement was finalized and signed by both parties, 21 months went by. there was a lot of back and forth in the negotiation process and paperwork between the university and proquest. • inconsistent lines of communication. there were multiple parties involved in the communication process and some of the emails began with one person only to be later transferred to someone else. this lack of consistency in the communication lines made it difficult to determine who was in charge of particular tasks at certain stages of the process. conclusion and recommendations although problems were encountered at the beginning, implementation of the harvesting process at unf was a complete success. once the process started, it ran smoothly without complications. harvests were performed on schedule and no issues with unauthorized content been pulled from the oai were faced. fields used to alert the robot in the oai of the etds authorized for harvesting worked as planned, and so did the embargo log used to identify and pull the out of embargo etds. it should be noted that digital commons users who want to exclude embargoed etds from displaying in the oai can do so by setting up an optional yes/no button in their submission form. this button prevents metadata of particular records from displaying in the oai feed. we did not pursue this option because we have been using the etd metadata that displays in th e oai to generate the marc records we send to oclc. in addition, we took the necessary precautions to avoid exposing full content of the embargoed etds in the oai feed. institutions planning to use this method should be very careful with the content they display in the oai as to avoid embargoed etds from been mistakenly pulled by proquest. access restrictions can be set by either suppressing the metadata of embargoed etds from displaying in the oai or by suppressing the urls with full access to the embargoed etds. the same precaution should be taken if planning to provide students with the choice to opt-in or out from proquest. altogether, the harvesting option proved to be a reliable solution to submit etds into proquest without having to compromise on students’ choice nor rely on complicated workflows with metadata transformations between ir and proquest schemas. institutions interested in adopting a simple, automated, post-ir method, while keeping the local workflow, should benefit from this method. information technology and libraries september 2020 using

respond to the covid-19 pandemic, creating a new service model jon goddard information technology and libraries | december 2020 https://doi.org/10.6017/ital.v39i4.12847 jon goddard (jgoddard@northshorepubliclibrary.org) is a librarian at the north shore public library, and a member of the ital editorial board. © 2020. during the covid-19 pandemic, public libraries have demonstrated, in many ways, their value to their communities. they have enabled their patrons to not only resume their lives, but to help them learn and grow. additionally, electronic resources offered to patrons through their library card have allowed people to be educated and entertained. the credit must go to the librarians, who initially fueled, and have maintained this level of service by re-writing the rules—creating a new service model. once libraries closed, librarians promoted ebooks and other important platforms available to patrons with their library cards. the result: the checkout of ebooks, and the use of these platforms rose, exponentially. community engagement became completely virtual with librarians, and those who provide library programs to the public, providing services on platforms that they may or may not have heard of, such as zoom and discord. as libraries re-opened, many offered real-time reference services, as well as seamless and contactless curbside service, providing a sense of control and continuity amongst the chaos. exponential increases in electronic resource usage overdrive, which is currently used by nearly 90% of public libraries in the united states to manage both ebook and audiobook collections, saw an exponential increase in its usage. since the lockdown began in mid-march, the daily average for ebook checkouts have been consistently 52% above pre-covid periods. additionally, new users to the platform have been consistently double and triple 2019 highs.1 library staff have been helping readers during this time to ensure they obtain access with their devices. in suffolk county, new york, where new patron registration to overdrive is up 72% from last year (as of august 2020), there has been no shortage of requests for help.2 with kids being home from school and learning virtually, it is no surprise that ebook readership skyrocketed amongst ya and juvenile readers with an 87% increase from last year. 3 to help them with their homework and studies, families turned to online tutoring. in suffolk county, new york, the usage of the brainfuse online live tutoring service has been consistently up by nearly 50% during the school closures.4 gale, a cengage company, which offers miss humblebee's academy, a virtual learning program for preschoolers, saw its user sessions increase by 100% from the previous year.5 mailto:jgoddard@northshorepubliclibrary.org information technology and libraries december 2020 public libraries respond to the covid-19 pandemic | goddard 2 adults, also eager to learn new skills, took to online courses as well. gale courses saw a 50% increase in enrollments from march-july from the previous year. likewise, gale presents: udemy, which offers on-demand video courses, saw just over 21,000 course enrollments from marchjune.6 to help those who did not have sufficient broadband wifi to use these necessary resources and platforms, many libraries left their wifi on even when the building was closed to allow access to those in the vicinity of the building. in addition, many libraries purchased wifi hotspots to lend to their patrons. according to pew research, approximately 25% of households do not have a broadband internet connection at home.7 while public libraries cannot provide the only local solution to this gap, here are other steps libraries have been taking during the shutdown: • strengthening wireless signals so people can access wireless from outside library buildings. • hosting drive-up wifi hotspot locations. • partnering with schools to obtain and distribute wifi hotspots to families in need. community engagement virtually community engagement has been vital since the covid-19 lockdown. both librarians and those who provide library programs to the public had to quickly adjust to the virtual world in which we were suddenly living. using a mixture of social media platforms, including facebook live and stories, discord, instagram, youtube, zoom, and gotomeeting, librarians flocked to the internet, providing a wide range of programming. even those libraries that did not previously have any virtual programs managed to very quickly provide quality programs to their patrons. virtual programming was not available at the san josé public library (sjpl) prior to the shutdown. librarians quickly started to move programs online, including story time, and created a program called spring into reading, similar to the summer reading program, to continue to encourage families to read together. they also started a weekly recorded story time, so patrons could call the library and use their phones to hear a story. to date, sjpl has hosted over 2,000 virtual events since the lockdown began on march 17th.8 some libraries, like the oceanside library in new york, were offering virtual programs before the pandemic. when the library closed on march 13, the team started planning to move completely virtual. two days later, the library was offering four programs a day, including story times, book chats, and book clubs. by the end of the week, they were offering eight programs a day.9 in april, may, and june, they found book discussions and story times were the most popular programs. they then started to open their programs to people from out of state, partnering with other libraries. the result? program attendance has increased and several zoom meeting rooms have been maxed out.10 through the lockdown, library patrons have been exercising, listening to concerts, taking virtual vacations, learning new skills, cooking, playing games, and reducing stress. this incredible information technology and libraries december 2020 public libraries respond to the covid-19 pandemic | goddard 3 adaption was only possible due to library worker’s quick thinking and a never-ending determination to help. delivering information and materials with a new service model at the san jose public library (sjpl), which has over 500,000 library members, library staff had to quickly shift to a new online reality just after the shutdown. to help patrons get the most from their electronic resources, sjpl used libanswers to post faqs and email responses to their issues and questions. when a librarian was available, patrons could use libchat to ask questions in real-time. because no one was in the library buildings to answer phones, libanswers and libchat became the only way the public could communicate with staff. chat reference conversations increased by nearly 400%—from approximately 40 chat sessions per day to 160 per day. the chat service was also made available in spanish, vietnamese, and chinese. when the library implemented its express pickup service, sjpl utilized the spaces functionality in libcal to allow patrons to create pickup appointments. when patrons arrived at the library for their appointment, the sms functionality in libanswers allowed patrons to text staff upon arrival. through the city of san josé’s sj access initiative, which aims to help bridge the digital divide in the city, sjpl worked closely with other city departments, and the santa clara county office of education, to purchase approximately 16,000 high-speed at&t hotspots for students and the public.11 working towards the new normal the american library association (ala) is committed to advocate strongly for libraries on several different fronts. thanks to thousands of advocate communications with congress, libraries secured $50 million for the institute of museum and library services (imls) in the coronavirus aid, relief, and economic security (cares) act. this enabled libraries and museums to apply for grants during this time of need.12 in addition, the ala is currently advocating for the passage of the library stabilization fund act (s.4181 / h.r.7486) to allow libraries to retain staff, maintain services, and safely keep communities connected and informed. the legislation calls for $2 billion in emergency recovery funding for america's libraries through the institute of museum and library services (imls).13 while the ala is rightly advocating for these emergency funds, public librarians and administrators should take advantage of this time to strategically review what has been put into place to react to the covid-19 pandemic, and plan for the long term. while it is true that libraries are physical spaces, they are also technology-driven services for learning and connections for all ages. additionally, they have shown that due to this new service model, access has expo nentially

introducing zoomify image | smith 55 column title editor author id box for 3 column layout returning classification to the catalog | bland and stoffan 55 communications robert n. bland and mark a. stoffan returning classification to the catalog the concept of a classified catalog, or using classification as a form of subject access, has been almost forgotten by contemporary librarians. recent developments indicate that this is changing as libraries seek to enhance the capabilities of their online catalogs. the western north carolina library network (wncln) has developed a “classified browse” feature for its shared online catalog that makes use of library of congress classification. while this feature is not expected to replace keyword searching, it offers both novice and experienced library users another way of identifying relevant materials. classification to modern librari-ans is almost exclusively a tool for organizing and arranging books (or other physical media) on shelves. the role of classification as a form of subject access to collections through the public catalog—the concept of the classified catalog—has been almost forgotten. from a review of the literature, it does not appear that any major u.s. library has supported a classified catalog since boston university libraries closed its classified catalog in 1973.1 to be sure, nearly all online catalogs nowadays have some form of what is called a “call number search” or a “shelf list browsing capability” that is based on classification, but this is a humble and little-used feature because it requires that a call number (or at least a call number stem) be known and entered by the user, when no verbal index to the classification is available online. this search methodology provides nothing in the way of a systematic and hierarchical arrangement and display of subject classes, complete with accompanying verbal descriptions, that the classified catalog seeks to accomplish. but as karen markey put it in her recent review of classification and the online catalog, “to this day, the only way in which most end users experience classification online is through their online catalog’s shelf list browsing capability.”2 there are signs that this situation is changing. the recently released endeca-based catalog at north carolina state university libraries uses library of congress classification (lcc) in a prominent way to provide for browsing of the collection without need of the user entering any search terms at all.3 the lcc outline is presented on the main search entry screen with verbal captions describing the classes, allowing users to navigate through several layers of the outline to retrieve with a click of the mouse bibliographic records for materials assigned to those classes. in a converse way, the new online catalog being developed by the florida center for library automation uses lc classification as a kind of back end to keyword searching. following a keyword search, a user can limit the results set by confining it to a designated lcc range chosen again from an online display of the lcc outline.4 both of these catalogs use three levels of the lcc outlines from the most general single letter level classes (q for sciences, for example) through the two-letter classes for more specific subjects (qc for physics, qd for chemistry) to an even finer granularity with designated numeric ranges within the two-letter classes identifying specific subdisciplines, (qd241–qd441 for organic chemistry). the western north carolina library network (wncln) has been experimenting with classification as a retrieval tool in the public catalog for some time,5 and it has just implemented the first version of what we call a classified catalog browse in our innovative millennium system.6 like the two catalogs just mentioned, the classified catalog browse is based on software that is external to the ils software and integrated with that software through linking and webpage designs. also, like the previously discussed catalogs, it is robert n. bland (bland@unca.edu) is associate university librarian for technical services, university of north carolina at asheville. mark stoffan (mstoffan@ fsu.edu) is associate director for library technology at florida state university, tallahassee. figure 1. level 1 of lc classification in wncln webpac 56 information technology and libraries | june 200856 information technology and libraries | september 2008 based on scanning and incorporating into the catalog the lcc outlines as published by the library of congress. the wncln catalog goes a step further, however, in bringing the entire lc classification online down to the individual class number level—at least that portion of the classification that is actually used in our catalog. this is done through extracting class numbers and associated subject headings from bibliographic and authority records in our catalog and building an online classification display with descriptive captions (a verbal index) from these bibliographic and authority records. the result is a hierarchical display (to continue the example from above) not only of qc241–qd441 for organic chemistry but within this, qd271 for chromatographic analysis, qd273 for organic electrochemistry, and so on. the design of our interface presents this as a fourth level to which the user can “drill” down beginning with q for sciences, qd for chemistry, qd241–qd441 for organic chemistry, and finally qd271 for chromatographic analysis (figures 1–4.) from this fourth level,the user can click an associated link to execute a search of the catalog by the class number in question using the call number search function of the ils (figure 5); a second link for that class number will present the same list of titles but sorted by “most popular” (i.e., the items that have been checked out most frequently) from a separate but linked external database (figure 6); a third link will search the catalog by the associated subject heading for the class (figure 7); and finally a fourth link will show other subject headings that have been used in the catalog with this specific class number (figure 8). what does having the lc classification online in our catalog accomplish for our users? part of the point of our project is to answer this very question. chan and others7 have theorized that incorporation of the classification system into the catalog as a retrieval tool can figure 2. level 2 of lc classification in wncln webpac figure 3. level 3 of lc classification in wncln webpac provide enhanced subject access that is not possible through standard alphabetical subject headings and keyword searching alone. early studies by markey and others at oclc seem to have confirmed this with an online version of the dewey decimal classification.8 since (as far as we know) the library of congress classification has not really been tested as an online retrieval tool in a live catalog up to now, our implementation will serve as a kind of test bed for this hypothesis. how actual users in fact exploit this feature is of course only something that experience will introducing zoomify image | smith 57returning classification to the catalog | bland and stoffan 57 tell. a cursory look, however, would seem to indicate definite advantages to this approach. first of all, many studies indicate that two of the major sources of failure with subject retrieval in online systems are misspellings and poor choice of search terms by users. no figure 4. level 4 of lc classification in wncln web:pac figure 5. call number search display in wncln matter how far we may try to go with keyword searching and relevance ranking, no online library retrieval system is likely to do much with “napolyan’s fites” when what the user is looking for are books on the military campaigns of the emperor napoleon. with the classification system and verbal index online most of these problems are eliminated, since users can navigate to a subject of choice without ever entering a search term. moreover, given the design of the verbal index based on library of congress subject headings, the user is led to actual subject headings used in the catalog, which should provide for precise retrieval beyond what is ordinarily possible with keywords even when entered correctly, and (importantly) a retrieval set that is always greater than zero. the infamous and frustrating problem of “no hits” is eliminated. secondly, the great attraction of the classified catalog approach is that it arranges subjects in a hierarchical fashion based on integral connections among the topics in a way that cannot be accommodated in an alphabetic subject approach because of the vagaries of spelling. the topics “violence,” “social conflict,” and “conflict management,” for example, obviously spread out in an alphabetical subject list, are collocated in the classified catalog under the class “hm1106–hm1171 interpersonal relations” (figure 9), allowing the user to find references to materials all in one place in the catalog just as the classification system arranges the books on these subjects all in one place on the library shelves. alphabetical subject indexes, of course, attempt to ameliorate this problem by means of cross references, but there is clearly a limit to how far one can go with this approach. finally, the classified catalog provides an efficient way for collection development staff to review specific subject areas and to make better informed purchasing decisions regarding the collections. in the wncln design, the classes at the bottom level of the hierarchy are linked to the catalog by call number and subject headings, and each class carries an indication of the number of items assigned that class number. the classes are also linked to an external database that shows the frequency 58 information technology and libraries | june 200858 information technology and libraries | september 2008 of circulation of items in the class as well as title and date of publication. a quick review of this list can inform a bibliographer of circulation rates as well as the currency of materials in the class. as mentioned, the captions that are displayed with the lcc hierarchy in the wncln catalog are extracted from subject headings and authority records present in our catalog. readers familiar with lc marc record services may wonder why we took this approach to building the verbal index rather than using the information available in the lc marc classification records. machine-readable records for lc classification are now available in marc format. these files include records for each individual class number with a corresponding verbal caption. while we did experiment with using these files, cost and complexity determined that we go another direction. the lc classification files are huge, containing hundreds of thousands of classification numbers that we do not now and probably never would use in our wncln catalog simply because we (unlike lc) have no materials on these subjects. while these records could be filtered out by matching against lc class numbers that are found in our catalog and discarding non-matches, this would add yet another level of processing to an already complex process, as would handling the lc table subdivisions that are used in the lc schedules and that are separate from the standard class numbers. secondly, the lc marc classification files require a subscription costing several thousands dollars per year, as well as a substantial payment for the retrospective file needed to begin building the database of class numbers. on the other hand, extracting the verbal index from subject headings and authority records in our own catalog adds no cost to our processing. these headings and authority records are created and maintained, of course, as a standard part of the figure 6. most used titles display figure 7. subject search display in wncln cataloging process, and accordingly only headings and authority records that match materials owned by our libraries are included. the description or caption that is finally assigned to a class number is determined by a computer program that analyzes both authority records and bibliographic records found in our catalog that are assigned the class number in question, with the subject heading that is used most frequently as a primary subject generally being the one normally selected as the caption for the class. these class numbers with associated subject headings are processed then by another program, which eventually builds html files introducing zoomify image | smith 59returning classification to the catalog | bland and stoffan 59 representing the classification with links to the catalog and the external “most used” database as alluded to above. these standard html files, along with the files representing the first three levels of the lcc outline, are then loaded onto our web server to display the classification system online. figure 9. collocation of terms in the classified catalog figure 8. related subjects display in wncln a second advantage of this approach is that using the actual subject heading as the caption or description for the class makes it possible to use that caption as a direct link to a subject search in the catalog, as shown in the illustration in figure 4. a disadvantage is that the captions from the lcc files are designed to retain the hierarchy that is represented in the printed schedules in a visual way by formatting and indenting. captions derived from subject headings do not retain this feature. we have tried to accommodate this in our display of the schedules by replicating the class number ranges from the outline in the appropriate place in the full display of the schedules, thereby building a hierarchy from these ranges as genus and the individual class numbers as species. this does not manage to retain the full hierarchy of the lc schedules as shown in the printed schedules or as represented in lc’s online classification web product, but it is, we hope, an adequate surrogate for the purpose intended. in fact, in most cases, the captions derived from the extracted subject and authority headings match quite nicely the captions included in the actual lcc schedules, as shown in a comparison from the psychology classification of the hierarchy as it appears in our classified catalog browse and as it appears online in lc’s classification web product (figures 10 and 11). what is missing in our representation of the classification is not so much the subject content of the classes but the notes and information about literary form that are included in the actual lcc schedules. thus, our lcc online is not a strict image of the lcc as it would appear in printed or electronic form based on the hierarchies and captions devised by the lc. nor for that matter—despite our terminology— is it a true classified catalog, since only one classification (that used in the call number) is assigned to each item, whereas in a true classified catalog multiple classifications may be assigned to an item. it is nevertheless an online presentation of the lcc with links to our catalog that seeks to enhance subject access by exploiting the power of the classification system to organize materials by integral subject classes and to show relationships among subjects by a 60 information technology and libraries | june 200860 information technology and libraries | september 2008 hierarchical arrangement of classes as genus, species, and subspecies. and, perhaps just as importantly, it is an implementation that requires no additional cataloging effort on the part of our staff, nor any additional costs for data or processing other than the investment we have made in development of the software and the small amount of time required weekly to update the files. we do not expect that the classified catalog browse will replace keyword or subject searching as the primary means of subject access to our collections. we do believe that it promises to be a powerful and effective complement to our standard ils searches that may improve subject searching for both the novice and the experienced user. references 1. margaret hindle hazen,

 university  of  michigan   to  gather  data  on  linkage  failure:  the  method  used,  the  limiting  factors,  the  changes  made  in  methods,   an  analysis  of  the  data  collected,  and  a  report  of  steps  taken  locally  because  of  the  studies.  it  is  hoped   that  the  experiences  at  one  institution  may  be  applicable  more  broadly  and,  perhaps,  produce  a   stronger

academic  libraries.  but  not  all  user  transactions  result  in  access  to  the  desired  full  text.   maintaining  information  that  allows  the  user  to  reach  full  text  is  a  shared  responsibility  among   assorted  vendors,  publishers,  aggregators,  local  catalogers,  and  electronic  access  specialists.  the   collection  of  information  used  in  getting  to  full  text  can  be  thought  of  as  a  supply  chain.  to   maintain  this  chain,  libraries  need  to  enhance  the  basic  information  about  the  contents  of  each   vendor  package—a  collection  of  journals  bundled  for  sale  to  libraries—with  added  details  about   local  licenses  and  holdings.  these  added  details  need  to  be  maintained  over  time.  since  links,   platforms,  contracts,  and  subscriptions  change  frequently,  this  can  be  a  time-­‐consuming  process.   when  links  are  unsuccessfully  constructed  within  each  system,  considerable  troubleshooting  of  a   very  complex  process  is  required  to  determine  where  the  problem  lies.  because  so  much  of  the   transaction  is  invisible  to  the  user,  linking  services  have  come  to  be  taken  for  granted  by  the   community,  and  performance  expectations  are  very  high.  failure  to  reach  full  text  reflects  poorly   on  the  institutions  that  offer  the  links,  so  there  is  considerable  interest  for  and  value  to  the   institution  in  improving  performance.     kenyon  stuart  (kstuart@umich.edu)  is  senior  information  resources  specialist,  ken

 acquiring  a  solid  understanding  of   the  nature  and  frequency  of  problems  that  inhibit  full-­‐text  retrieval.  while  anecdotal  data  and   handling  of  individual  complaints  can  provide  incremental  improvement,  larger  improvement   resulting  from  systematic  changes  requires  more  substantial  data,  data  that  characterizes  the   extent  of  linking  failure  and  the  categories  of  situations  that  inhibit  it.   literature  review   openurl  link  resolvers  are  “tool[s]  that  helps  library  users  connect  to  their  institutions’   electronic  resources.  the  data  that  drives  such  a  tool  is  stored  in  a  knowledge  base.”1  since  the   codification  of  the  openurl  as  an  ansi/niso  standard  in  2004,2  openurl  has  become,  in  a  sense,   the  glue  that  holds  the  infrastructure  of  traditional  library  research  together,  connecting  citations   and  full  text.  it  is  well  recognized  that  link  resolution  is  an  imperfect  science.  understanding  what   and  how  openurls  fail  is  a  time-­‐consuming  and  labor-­‐intensive  process,  typically  conducted   through  analysis  of  log  files  recording  attempts  by  users  to  access  a  full-­‐text  item  via  openurl.   research  has  been  conducted  from  the  perspective  of  openurl  providers,  showing  which   metadata  elements  encoded  in  an  openurl  were  most  common  and  most  significant  in  leading  to   an  appropriate  full-­‐text  version  of  the  article  being  cited.  in  2010,  chandler,  wiley,  and  leblanc   reported  on  a  systematic  approach  they  devised,  as  part  of  a  mellon  grant,  to  review  the  outbound   openurls  from  l’année  philologique.3  they  began  with  an  analysis  of  the  metadata  elements   included  in  each  openurl  and  compared  this  to  the  standard.  they  found  that  elements  critical  to   the  delivery  of  a  full-­‐text  item,  such  as  the  article’s  starting  page,  were  never  included  in  the   openurls  generated  by  l’année  philologique.4  their  work  led  to  the  creation  of  the  improving   openurls  through  analytics  (iota)  working  group  within  the  national  information  standards   organization  (niso).   iota,  in  turn,  was  focused  on  improving  openurl  link  quality  at  the  provider  end.  “the  quality  of   the  data  in  the  link  resolver  knowledge  base  itself  is  outside  the  scope  of  iota;  this  is  being   addressed  through  the  niso  kbart  initiative.”5,6  where  iota  provided  tools  to  content  providers   for  improving  their  outbound  openurls,  kbart  provided  tools  to  knowledge  base  and  linking   tool  providers  for  improving  their  data.  pesch,  in  a  study  to  validate  the  iota  process,  discovered   that  well-­‐formed  openurls  were  generally  successful,  however:   the  quality  of  the  openurl  links  is  just  part  of  the  equation.  setting  the  proper  expectations   for  end  users  also  need  to  be  taken  into  consideration.  librarians  can  help  by  educating  their   users  about  what  is  expected  behavior  for  a  link  resolver  and  end  user  frustrations  can  also  be   reduced  if  librarians  take  advantage  of  the  features  most  content  providers  offer  to  control   when  openurl  links  display  and  what  the  links  say.  where  possible  the  link  text  should   indicate  to  the  user  what  they  will  get  when  they  click  it.7       information  technology

 method  for  reviewing  openurl  data  and  identifying  the   root  causes  of  failures.  8  through  testing  of  actual  openurls  in  each  of  their  systems,  they  arrived   at  a  series  of  steps  that  could  be  taken  by  other  libraries  to  proactively  raise  openurl  resolution   success  rates.  several  specific  recommendations  include  “optimize  top  100  most  requested   journals”  and  “optimize  top  ten  full  text  target  providers.”9  that  is,  make  sure  that  openurls   leading  to  content  from  the  most  frequently  used  journals  and  content  sources  are  tested  and  are   functioning  correctly.  chen  describes  a  similar  analysis  of  broken  link  reports  derived  from   bradley  university  library’s  sfx  implementation  over  four  years,  with  a  summary  of  the  common   reasons  links  failed.10  similarly,  o’neill  conducted  a  small  usability  study  whose  recommendations   included  providing  “a  system  of  support  accessible  from  the  page  where  users  experience   difficulty,”11  although  her  recommendations  focused  on  inline,  context-­‐appropriate  help  rather   than  error-­‐reporting  mechanisms.   not  found  in  the  literature  are  several  systematic  approaches  that  a  library  can  take  to  proactively   collect  problem  reports  and  manage  the  knowledge  base  accordingly.   method   we  have  taken  a  two-­‐pronged  approach  to  improving  link  resolution  quality,  each  relying  on  a   different  kind  of  input.  the  first  uses  problem  reports  submitted  by  users  of  our  summontm-­‐ powered  article  discovery  tool,  articlesplus.12  the  second  focuses  on  the  most  commonly-­‐accessed   full-­‐text  titles  in  our  environment,  based  on  reports  from  360  link.  we  have  developed  this  dual   approach  in  the  expectation  that  we  will  catch  more  problems  on  lesser-­‐used  full-­‐text  sources   through  the  first  approach,  and  problems  whose  resolution  will  benefit  the  most  individuals   through  the  second.   user  reports   the  university  of  michigan  library  uses  summon  as  the  primary  article  discovery  tool.  when  a   user  completes  a  search  and  clicks  the  “mget  it”  button  (see  figure  1)—mget  it  is  our  local  brand   for  the  entire  full-­‐text  delivery  process—the  user  is  directed  to  the  actual  document  through  one   of  two  mechanisms:   1. access  to  the  full-­‐text  article  through  a  summon  index-­‐enhanced  direct  link.  (some  of   summon’s  full-­‐text  content  providers  contribute  a  url  to  summon  for  direct  access  to  the   full  text.  this  is  known  as  an  index-­‐enhanced  direct  linking  [direct  linking].)   2. access  to  the  full  text  article  through  the  university  library’s  link  resolver,  360  link.  at  this   point,  one  of  two  things  can  happen:   a. the  university  library  has  configured  a  number  of  full-­‐text  sources  as  “direct  to  full   text”  links.  when  a  citation  leads  to  one  of  these  sources,  the  user  is  directed  to  the   article  (or  as  close  to  it  as  the  content  provider’s  site  allows  (sometimes  to  an  issue       measuring  journal  linking  success  from  a  discovery  service  |  stuart,  varnum,  and   ahronheim   55   table  of  contents,  sometimes  to  a  list  of  items  in  the  appropriate  volume,  and—rarely  in   this  instance——to  the  journal’s  front  page;  the  last  outcome  is  rare  in  our  environment   because  the  university  library  prefers  full-­‐text  links  that  get  closer  to  the  article  and   has  configured  360  link  for  that  outcome).     b. for  those  full-­‐text  sources  that  do  not  have  direct-­‐to-­‐article  links,  360  link  is   configured  to  provide  a  range  of  possible  delivery  mechanisms,  including  journal-­‐,   volume-­‐  or  issue-­‐level  entry  points,  document-­‐delivery  options  (for  cases  where  the   library  does  not  license  any  full-­‐text  online  sources),  the  library  catalog  (for  identifying   print  holdings  for  a  journal),  and  so  on.   from  the  user  perspective,  mechanisms  1  and  2a  are  essentially  identical.  in  both  cases,  a  click  on   the  mget  it  icon  takes  the  user  to  the  full  text  in  a  new  browser  window.  if  the  link  does  not  lead  to   the  correct  article  for  any  reason,  there  is  no  way  in  the  new  window  for  the  library  to  collect  that   information.  users  may  consider  item  2b  results  as  a  failure  because  the  article  is  not  immediately   perceptible,  even  if  the  article  is  actually  available  in  full  text  after  two  or  more  subsequent  clicks.   because  of  this  user  perception,  we  interpreted  2b  results  as  “failures.”     figure  1.

 in  the  articlesplus  search-­‐results  interface  each  time  the  full-­‐ text  icon  appears  (see  the  right  side  of  figure  1).  when  the  user  clicks  this  problem-­‐reporting  link,   they  are  taken  to  a  qualtrics  survey  form  that  asks  for  several  basic  pieces  of  information  from  the   user  but  also  captures  the  citation  information  for  the  article  the  user  was  trying  to  reach  (see   figure  2).         information  technology  and  libraries  |  march  2015   56     figure  2.  survey  questionnaire  for  reporting  linking  problems   this  survey  instrument  asks  the  user  to  characterize  the  type  of  delivery  failure  with  one  of  four   common  problems,  along  with  an  “other”  text  field:   • there  was  no  article   • i  got  the  wrong  article   • i  ended  up  at  a  page  on  the  journal's  web  site,  but  not  the  article   • i  was  asked  to  log  in  to  the  publisher's  site   • something  else  happened  (please  explain):   the  form  also  asks  for  any  additional  comments  and  requires  that  the  user  provide  an  email   address  so  that  library  staff  can  contact  the  user  with  a  resolution  (often  including  a  functioning   full-­‐text  link)  or  to  ask  for  more  information.   in  addition  to  the  information  requested  from  the  user,  hidden  fields  on  this  form  capture  the   summon  record  id  for  the  article,  the  ip  address  of  the  user’s  computer  (to  help  us  identify  if  the   problem  could  be  a  related  to  our  ezproxy  configuration),  a  time  and  date  stamp  of  the  report’s   submission,  and  the  brand  and  version  of  web  browser  being  used.       measuring  journal  linking  success  from  a  discovery  service  |  stuart,  varnum,  and   ahronheim   57   the  results  of  the  form  are  sent  by  email  to  the  university  library’s  ask  a  librarian  service,  the   library’s  online  reference  desk.  ask  a  librarian  staff  make  sure  that  the  problem  is  not  associated   with  the  individual  user’s  account  (that  they  are  entitled  to  get  full  text,  that  they  were  accessing   the  item  from  on  campus  or  via  the  proxy  server  or  vpn,  etc.).  when  user-­‐centric  problems  are   ruled  out,  the  problem  is  passed  on  to  the  library’s  electronic  access  unit  in  technical  services  for   further  analysis  and  resolution.   random  sampling   user-­‐reported  problems  are  only  one  picture  of  issues  in  the  linking  process.  we  were  concerned   that  user  reports  might  not  be  the  complete  story.  we  wanted  to  ensure  that  our  samples   represented  the  full  range  of  patron  experiences,  not  just  that  of  the  ones  who  reported.  so,  to  get   a  different  perspective,  we  instituted  a  series  of  random  sample  testing  using  logs  of  document   requests  from  the  link  resolver,  360  link.   2011  linking  review   our  first  large-­‐scale  review  of  linking  from  articlesplus  was  conducted  in  2011.  this  first  approach   was  based  on  a  log  of  the  summon  records  that  had  appeared  in  patron  searches  and  for  which   our  link  resolver  link  had  been  clicked.  for  this  test  we  chose  a  slice  of  the  log  covering  the  period   from  january  30–february  12,  2011.  this  period  was  chosen  because  it  was  well  into  the  academic   term  and  before  spring  break,  so  it  would  provide  a  representative  sample  of  the  searches  people   had  performed.  the  resulting  slice  contained  13,161  records.  for  each  record  the  log  contained   the  summon  id  of  the  record.  we  used  this  to  remove  duplicate  records  from  the  log  to  ensure  we   were  not  testing  linking  for  the  same  record  more  than  once,  leaving  us  with  a  spreadsheet  of   10,497  records,  one  record  per  row.  from  the  remaining  records  we  chose  a  sample  of  685   records  using  a  random  number  generator  tool,  research  randomizer   (http://www.randomizer.org/form.htm),  to  produce  a  random,  nonduplicating  list  of  685   numbers  with  values  from  1  to  10,497.  each  of  the  685  numbers  produced  was  matched  to  the   corresponding  row  in  the  spreadsheet  starting  with  the  first  record  listed  in  the  spreadsheet.  for   each  record  we  collected  the  data  in  figure  3.                 information  technology  and  libraries  |  march  2015   58   1.  the  summon  id  of  the  record   2.  the  raw  openurl  provided  with  the  record.   3.  a  version  of  the  openurl  that  may  have  been  locally  edited  to  put  dates  in  a  standard   format.   4.  the  final  url  provided  to  the  user  for  linking  to  the  resource.  this  would  usually  be   the  openurl  from  #3  containing  the  metadata  used  by  the  link  resolver  to  build  its   full-­‐text  links.  currently  it  is  an  intermediary  url  provided  by  the  summon  api.  this   url  may  lead  to  an  openurl  or  to  a  direct  link  to  the  resource  in  the  summon  record.   5.  the  classification  of  the  link  in  the  summon  record.  this  was  either  “full  text  online”   or  “citation-­‐only.”   6.  the  date  the  link  resolver  link  was  clicked.   7.  the  page  in  the  summon  search  results  the  link  resolver  link  was  found.   8.  the  position  within  the  page  of  search  results  where  the  link  resolver  link  was  located.   9.  the  search  query  that  produced  the  search  results.   figure  3.  data  points  collected   the  results  from  this  review  were  somewhat  disappointing,  with  only  69.5%  of  the  citations   tested  leading  directly  to  full  text.  at  the  time  direct  linking  did  not  yet  exist,  so  “direct  to  full  text”   linking  was  only  available  through  the  1-­‐click  feature  of  360  link.  the  1-­‐click  feature  attempts  to   lead  patrons  directly  to  the  full  text  of  a  resource  without  first  going  through  the  360  link  menu.   1-­‐click  was  used  for  579  or  84.5%  of  the  citations  tested  with  15.3%  leading  to  the  360  link  menu.   of  the  citations  that  used  1-­‐click,  476  or  82.2%  led  directly  to  full  text,  so  when  1-­‐click  was  used  it   was  rather  successful.  links  for  about  30.5%  of  the  citations  led  either  to  a  failed  attempt  to  reach   full  text  through  1-­‐click  or  directly  to  the  360  link  menu.  the  2011  review  included  looking  at  the   full-­‐text  links  that  360  link  indicated  should  lead  directly  to  the  full  text  as  opposed  to  the  journal,   volume  or  issue  level.  when  we  reviewed  all  of  the  “direct  to  full  text”  links  generated  by  360  link,   not  only  the  ones  used  by  1-­‐click,  we  found  a  variety  of  reasons  why  those  links  did  not  succeed  in   leading  to  the  full  text.  the  top  five  reasons  found  for  linking  failures  are  the  following:   1. incomplete  target  collection   2. incorrect  syntax  in  the  article/chapter  link  generated  by  360  link   3. incorrect  metadata  in  the  summon  openurl   4. article  not  individually  indexed   5. target  error  in  targeturl  translation       measuring  journal  linking  success  from  a  discovery  service  |  stuart,  varnum,  and   ahronheim   59   collectively,  these  reasons  were  associated  with  the  failure  of  71.5%  of  the  “direct  to  full  text”   links.  as  we  will  show  later,  these  problems  were  also  noted  in  our  most  recent  review  of  linking   quality.   move  to  quarterly  testing   after  this  review  in  2011,  we  decided  to  perform  quarterly  testing  of  the  linking  so  we  would  have   current  data  on  the  quality  of  linking.  this  would  give  us  information  on  the  effectiveness  of  any   changes  we  and  proquest  had  made  independently  to  improve  the  linking.  we  could  see  where   linking  problems  found  in  previous  testing  had  been  resolved  and  where  new  ones  might  exist.     however,  we  needed  to  change  how  we  created  our  sample.  while  the  data  gathered  in  2011   provided  much  insight  into  the  workings  of  360  link,  testing  the  685  records  produced  2,210  full-­‐ text  links.  gathering  the  data  for  such  a  large  number  of  links  required  two  months  of  part-­‐time   effort  by  two  staff  members  as  well  as  an  additional  month  of  part-­‐time  effort  by  one  staff  member   for  analysis.  this  would  not  be  workable  for  quarterly  testing.  as  an  alternative  we  decided  to  test   two  records  from  each  of  the  100  serials  most  accessed  through  the  link  resolver.  this  gave  us  a   sample  we  could  test  and  analyze  within  a  quarter  based  on  serials  that  our  patrons  were  using.   we  felt  that  we  could  gather  data  for  such  a  sample  within  three  to  four  weeks  instead  of  two   months.  the  list  was  generated  using  the  “click-­‐through  statistics  by  title  and  issn  (journal  title)”   usage  report  generated  through  the  proquest  client  center  administration  gui.  we  searched  for   each  serial  title  within  summon  using  the  serial’s  issn  or  the  serial’s  title  when  the  issn  was  not   available.     we  ordered  the  results  by  date,  with  the  newest  records  first.  we  wanted  an  article  within  the  first   two  to  three  pages  of  results  so  we  would  have  a  recent  article,  but  not  one  so  new  it  was  not  yet   available  through  the  resources  that  provide  access  to  the  serial.  then  we  reordered  the  results  to   show  the  oldest  records  first  and  chose  an  article  from  the  first  or  second  page  of  results.  our  goal   was  to  choose  an  article  at  random  from  the  second  or  third  page  while  ignoring  the  actual  content   of  the  article  so  as  not  to  introduce  a  selection  bias  by  publisher  or  journal.  another  area  where   our  sample  was  not  truly  random  involved  supplement  issues  of  journals.  one  problem  we  found   with  the  samples  collected  was  that  they  contained  few  items  from  supplemental  issues  of   journals.  linking  to  articles  in  supplements  is  particularly  difficult  because  of  the  different  ways   supplement  information  is  represented  among  different  databases.  to  attempt  to  capture  linking   information  in  this  case  we  added  records  for  articles  in  supplemental  issues.  those  records  were   chosen  from  journals  found  in  earlier  testing  to  contain  supplemental  issues.  we  searched   summon  for  articles  within  those  supplemental  issues  and  selected  one  or  two  to  add  to  our   sample.   one  notable  thing  is  the  introduction  of  direct  linking  in  our  summon  implementation  between   the  reviews  for  the  first  and  second  quarters  of  2012.  proquest  developed  direct  linking  to       information  technology  and  libraries  |  march  2015   60   improve  linking  to  resources  (including  but  not  limited  to  full  text  of  articles)  through  summon.   instead  of  using  an  openurl  which  must  be  sent  to  a  link  resolver,  direct  linking  uses   information  received  from  the  providers  of  the  records  in  summon  to  create  links  directly  to   resources  through  those  providers.  ideally,  since  these  links  use  information  from  those  providers,   direct  linking  would  not  have  the  problems  found  with  openurl  linking  through  a  link  resolver   such  as  360  link.  not  all  links  from  summon  use  direct  linking,  and  as  a  result  we  had  to  take  into   account  the  possibility  that  any  link  we  clicked  could  use  either  openurl  linking  or  direct  linking.   current  review:  back  to  random  sampling   while  the  above  sampling  method  resulted  in  useful  data,  we  also  found  it  had  some  limitations.   when  we  performed  the  review  for  the  second  quarter  of  2012,  we  found  a  significant  increase  in   the  effectiveness  of  360  link  since  the  first  quarter  2012  review.  this  is  further  described  in  the   findings  section  of  this  article.  we  were  able  to  trace  some  of  this  improvement  to  changes   proquest  had  made  to  360  link  and  to  the  openurls  produced  from  summon.  however,  we  were   unable  to  fully  trace  the  cause  of  the  improvement  and  were  unable  to  determine  if  this  was  real   improvement  that  would  be  persistent.  to  resolve  these  problems,  we  have  returned  to  using  a   random  sample  in  our  latest  review,  but  with  a  change  in  methods.     current  review:  determining  the  sample  size   we  wanted  to  perform  a  review  that  would  be  statistically  relevant  and  could  help  us  determine  if   any  changes  in  linking  quality  were  persistent  and  not  just  a  one-­‐time  event.  instead  of  testing  a   single  sample  each  quarter  we  decided  to  test  a  sample  each  month  over  a  period  of  months.  one   concern  with  this  was  the  sample  size,  as  we  wanted  a  sample  that  would  be  statistically  valid  but   not  so  large  we  could  not  test  it  within  a  single  month.  we  determined  that  a  sample  size  of  300   would  be  sufficient  to  determine  if  any  month-­‐to-­‐month  changes  represent  a  real  change.   however,  in  previous  testing  we  had  learned  that  because  of  re-­‐indexing  of  the  summon  records,   summon  ids  that  were  valid  when  a  patron  performed  a  search  might  no  longer  be  valid  by  the   time  of  our  testing.  we  wanted  a  sample  of  300  still-­‐valid  records,  so  we  selected  a  random  sample   larger  than  that  amount.  so,  we  decided  to  test  600  records  each  month  to  determine  if  the   summon  ids  were  still  valid.   current  review:  methods   when  generating  each  month's  sample  we  used  the  same  method  as  in  2011.  we  asked  our  web   systems  group  for  the  logs  of  full-­‐text  requests  from  the  library’s  summon  interface  for  the  period   of  november  2012–february  2013.13  we  processed  each  month’s  log  file  within  two  months  of  the   user  interactions.  to  generate  the  600-­‐record  sample,  after  removing  records  with  duplicate   summon  ids,  we  used  a  random  number  generator  tool,  research  randomizer,  to  produce  a   random,  nonduplicating  list  of  600  numbers  with  values  from  1  to  the  number  of  unique  records.   each  of  the  600  numbers  produced  was  matched  to  the  corresponding  row  in  the  spreadsheet  of       measuring  journal  linking  success  from  a  discovery  service  |  stuart,  varnum,  and   ahronheim   61   records  with  unique  summon  ids.  once  the  600  records  were  tested  and  we  had  a  subset  with   valid  summon  ids,  we  generated  a  list  of  300  random,  nonduplicating  numbers  with  values  from  1   to  the  number  of  records  with  valid  summon  ids.  each  of  the  300  numbers  produced  was  matched   to  the  corresponding  row  in  a  spreadsheet  of  the  subset  of  records  with  valid  summon  ids.  this   gave  us  the  300-­‐record  sample  for  analysis.     testing  was  performed  by  two  people,  a  permanent  staff  member  and  a  student  hired  to  assist   with  the  testing.  the  staff  member  was  already  familiar  with  the  data  gathering  and  recording   procedure  and  trained  the  student  on  this  procedure.  the  student  was  introduced  to  the  library’s   summon  implementation  and  shown  how  to  recognize  and  understand  the  different  possible   linking  types:  summon  direct  linking,  360  link  using  1-­‐click,  and  360  link  leading  to  the  360   link  menu.  once  this  background  was  provided,  the  student  was  introduced  to  the  procedure  for   gathering  and  recording  data.  the  student  was  given  suggestions  on  how  to  find  the  article  on  the   target  site  if  the  link  did  not  lead  directly  to  the  article  and  how  to  perform  some  basic  analysis  to   determine  why  the  link  did  not  function  as  expected.  the  permanent  staff  member  reviewed  the   analysis  of  the  links  that  did  not  lead  to  full  text  and  applied  a  code  to  describe  the  reason  for  the   failure.     based  on  our  2011  testing,  we  expected  to  see  one  of  two  general  results  in  the  current  round.     1. 360  link  would  attempt  to  connect  directly  to  the  article  because  of  our  activating  the  1-­‐ click  feature  of  360  link  when  we  implemented  the  link  resolver.  with  1-­‐click,  360  link   attempts  to  lead  patrons  directly  to  the  full  text  of  a  resource  without  first  having  to  go   through  the  link  resolver  menu.  even  with  1-­‐click  active  we  provide  patrons  a  link  leading   to  the  full  360  link  menu,  which  may  have  other  options  for  leading  to  the  full  text  as  well   as  links  to  search  for  the  journal  or  book  in  our  catalog.     2. the  other  possible  result  was  the  link  from  summon  leading  directly  to  the  360  link  menu.     once  direct  linking  was  implemented  after  we  began  this  round,  a  third  result  became  possible  (a   direct  link  from  summon  to  the  full  text).     for  each  record  we  collected  the  data  shown  in  figure  4.                 information  technology  and  libraries  |  march  2015   62   1.      date  the  link  from  summon  record  was  tested.   2.      the  url  of  the  summon  record.   3.    *the  openurl  generated  by  clicking  the  link  from  summon.  this  was  the  url  in  the   address  bar  of  the  page  to  which  the  link  led.  this  is  not  available  when  direct  linking  is   used.   4.      the  issn  of  the  serial  or  isbn  of  the  book.   5.      the  doi  of  the  article/book  chapter  if  it  was  available.   6.      the  citation  for  the  article  as  shown  in  the  360  link  menu  or  in  the  summon  record  if   direct  linking  was  used.   7.    *each  package  (collection  of  journals  bundled  together  in  the  knowledgebase)  for  which   360  link  produced  an  electronic  link  for  that  citation.   8.    *the  order  in  the  list  of  electronic  resources  in  which  the  package  in  #7  appeared  in  the   360  link  menu.   9.    *the  linking  level  assigned  to  the  link  by  360  link.  this  level  indicates  how  close  to  the   article  the  link  should  lead  the  patron,  with  article-­‐level  or  chapter-­‐level  links  ideally   taking  the  patron  directly  to  the  article/book  chapter.  the  linking  levels  recorded  in  our   testing  starting  with  the  closest  to  full  text  were  article/book  chapter,  issue,  volume,   journal/book  and  database.   10.  *for  article-­‐level  links,  the  url  that  360  link  used  to  attempt  to  connect  to  the  article.   11.  for  all  full-­‐text  links  in  the  360  link  menu,  the  url  to  which  the  links  led.  this  was  the   link  displayed  in  the  browser  address  bar.   12.  a  code  assigned  to  that  link  describing  the  results.   13.  a  note  indicating  if  full  text  was  available  on  the  site  to  which  the  link  led.  this  was  only   an  indicator  of  whether  or  not  full  text  could  be  accessed  on  that  site  not  an  indicator  of   the  success  of  1-­‐click/direct  linking  or  the  article-­‐level  link.   14.  a  note  if  this  was  the  link  used  by  1-­‐click.   15.  a  note  if  direct  linking  was  used.   16.  a  note  if  the  link  was  for  a  citation  where  1-­‐click  was  not  used  and  clicking  the  link  in   summon  led  directly  to  the  360  link  menu.   17.  notes  providing  more  detail  for  the  results  described  by  #12.  this  included  error   messages,  search  strings  shown  on  the  target  site,  and  any  unusual  behavior.  the  notes   also  included  conclusions  reached  regarding  the  cause(s)  of  any  problems.   *  collected  only  if  the  link  resolver  was  used.   figure  4.  data  collected  from  sample       measuring  journal  linking  success  from  a  discovery  service  |  stuart,  varnum,  and   ahronheim   63   each  link  was  categorized  based  on  whether  it  led  to  the  full  text.  then  the  links  that  failed  were   further  categorized  on  the  basis  of  the  reason  for  failure  (see  figure  5  for  failure  categories).     1.        incorrect  metadata  in  the  summon  openurl.   2.        incomplete  metadata  in  the  summon  openurl.   3.        difference  in  the  metadata  between  summon  and  the  target.  in  this  case  we  were  unable  to   determine  which  site  had  the  correct  metadata.   4.        inaccurate  data  in  the  knowledgebase.  this  includes  incorrect  url  and  incorrect   issn/isbn.   5.        incorrect  coverage  in  the  knowledgebase.   6.        link  resolver  insufficiency.  the  link  resolver  has  not  been  configured  to  provide  deep   linking.  this  may  be  something  that  we  could  configure  or  something  that  would  require   changes  in  360  link.   7.        incorrect  syntax  in  the  article/chapter  link  generated  by  360  link.   8.        target  site  does  not  appear  to  support  linking  to  article/chapter  level.   9.        article  not  individually  indexed.  this  often  happens  with  conference  abstracts  and  book   reviews  which  are  combined  in  a  single  section.   10.    translation  error  of  the  “targeturl”  by  target  site.   11.    incomplete  target  collection.  site  is  missing  full  text  for  items  that  should  be  available  on   the  site.   12.    incorrect  metadata  on  the  target  site.   13.    citation-­‐only  record  in  summon.  summon  indicates  only  the  citation  is  available  so  access   to  full  text  is  not  expected.   14.    error  indicating  cookie  could  not  be  downloaded  from  target  site.  this  sometimes   happened  with  1-­‐click  but  the  same  link  would  work  from  the  360  link  menu.   15.    item  does  not  appear  to  have  a  doi.  the  360  link  menu  may  provide  an  option  to  search  for   the  doi.  sometimes  these  searches  fail  and  we  are  unable  to  find  a  doi  for  the  item.   16.    miscellaneous.  results  that  do  not  fall  into  the  other  categories.  generally  used  for  links  in   packages  for  which  360  link  only  provides  journal/book-­‐level  linking  such  as  directory  of   open

 for  each  month,  we  calculated  the  number  of  problems  reported   per  1,000  searches  and  per  1,000  full-­‐text  clicks.  graphed  over  time,  the  number  of  problem   reports  in  both  categories  shows  an  overall  decline.  see  figures  6  and  7.     figure  6.  problems  reported  per  1,000  articlesplus  searches  (june  2011–april  2014)     figure  7.  problems

  our  active  work  to  update  the  summon  and  360  link  knowledge  bases  began  in  june  2011.  the   change  to  summon  direct  linking  happened  on  february  27,  2012,  at  a  time  when  we  were   particularly  dissatisfied  with  the  volume  of  problems  reported.  we  felt  the  poor  quality  of   openurl  resolution  was  a  strong  argument  in  favor  of  activating  summon  direct  linking.  we   believe  this  change  led  to  a  noticeable  improvement  in  the  number  of  problems  reported  per   1,000  searches  (see  figure  6).  we  do  not  have  data  for  clicks  on  the  full-­‐text  links  in  our   articlesplus  interface  prior  to  march  2012,  but  do  know  that  reports  per  1,000  full-­‐text  clicks  have   been  on  the  decline  as  well  (see  figure  7).   findings   summary  of  random-­‐sample  testing  of  link  success     in  early  2013  we  tested  linking  from  articlesplus  to  gather  data  on  the  effectiveness  of  the  linking   and  to  attempt  to  determine  if  there  were  any  month-­‐to-­‐month  changes  in  the  effectiveness  that   could  indicate  persistent  changes  in  linking  quality.  in  this  section  we  will  review  the  data   collected  from  the  four  samples  used  in  this  testing.  we  will  discuss  the  different  paths  to  full  text,   direct  linking  vs.  openurl  linking  through  360  link,  and  their  relative  effectiveness.  we  will  also   discuss  the  reasons  we  found  for  links  to  not  lead  to  full  text.   paths  to  full-­‐text  access   as  shown  below  (see  table  1)  most  of  the  records  tested  in  summon  used  direct  linking  to   attempt  to  reach  the  full  text.  the  percentage  varied  with  each  sample  tested  but  they  ranged  from   61%  to  70%.  the  remaining  records  used  360  link  to  attempt  to  reach  the  full  text.  most  of  the   time  when  360  link  was  used,  1-­‐click  was  also  used  to  reach  the  full  text.  between  direct  linking   and  1-­‐click  about  93%  to  94%  of  the  time  an  attempt  was  made  to  lead  users  directly  to  the  full   text  of  the  article  without  first  going  through  the  360  link  menu.     sample  1   november  2012   sample  2   december  2012   sample  3   january  2013   sample  4   january  2013   direct  linking   205

 remaining  cases  were  situations  where  direct  linking/1-­‐click  did  not  lead   directly  to  the  full  text  or  we  reached  the  360  link  menu.       sample  1   november  2012   sample

 to  about  67%  of  the   time.   for  those  records  using  direct  linking  where  direct  linking  did  not  lead  directly  to  the  text,  the   result  was  usually  a  page  that  did  not

 testing,  not   only  the  ones  used  by  1-­‐click  (see  table  9),  we  see  more  causes  of  failure  than  with  1-­‐click.  most  of   the  failures  were  caused  by  five  general  problems:   1. incorrect  metadata  in  summon.   2. link  resolver  insufficiency.  we  mostly  used  this  classification  when  360  link  only  provided   links  to  the  main  journal  page  or  database  page  instead  of  links  to  the  article  and  we   thought  it  might  have  been  possible  to  generate  a  link  to  the  article.  sometimes  this  was   due  to  configuration  changes  that  we  could  have  made  and  sometimes  it  was  because  360   link  would  only  create  article  links  if  particular  metadata  was  available  even  if  other   sufficient  identifying  metadata  was  available.   3. incorrect  syntax  in  the  article/chapter  link  generated  by  360  link.   4. target  site  does  not  support  linking  to  the  article/chapter  level.   5. miscellaneous.  most  of  the  links  that  fell  in  this  category  were  ones  that  were  intended  to   go  the  main  journal  page  by  design.  these  were  for  journals  that  are  not  in  vendor-­‐specific   packages  in  the  knowledgebase  but  in  large  general  packages  with  many  journals  on   different  platforms.  because  there  is  no  common  linking  syntax,  article-­‐level  linking  is  not   possible.  this  includes  packages  containing  open  source  titles  such  as  directory  of  open   access  journals  (doaj)  and  packages  of

 user-­‐reported  errors  is  significantly  less  than  what  we  found  through  our   systematic  sampling  (see  table  2).  where  the  error  rate  based  on  user  reports  would  be  roughly   0.2%,  the  more  systematic  approach  showed  a  20%  error  rate.  relying  solely  on  user  reports  of   errors  to  judge  the  reliability  of  full-­‐text  links  dramatically  underreports  true  problems  by  a  factor   of  100.     conclusions  and  next  steps   comparison  of  user  reports  to  random  sample  testing  indicates  a  significant  underreporting  of   problems  on  the  part  of  users.  while  we  have  not  conducted  similar  studies  across  other  vendor   databases,  we  suspect  that  user-­‐generated  reports  likewise  significantly  lag  behind  true  errors.   future  research  in  this  area  is  recommended.     the  number  of  problems  discovered  in  full-­‐text  items  that  are  linked  via  an  openurl  is   discouraging;  however,  the  ability  of  the  summon  discovery  service  to  provide  accurate  access  to   full  text  is  an  overall  positive  because  of  its  direct  link  functionality.  more  than  95%  of  direct-­‐ linked  articles  in  our  research  led  to  the  correct  resource  (table  3).  one-­‐click  (openurl)   resolution  was  noticeably  poorer,  with  about  60%  of  requests  leading  directly  to  the  correct  full-­‐ text  item.  more  alarming,  we  found  that,  of  full-­‐text  requests  linked  through  an  openurl,  a  large       measuring  journal  linking  success  from  a  discovery  service  |  stuart,  varnum,  and   ahronheim   75   portion—20%—fail.  the  direct  links  (the  result  of  publisher-­‐discovery  service  negotiations)  are   much  more  effective.  this  discourages  us  from  feeling  any  complacency  about  the  effectiveness  of   our  openurl  link  resolution  tools.  the  effort  spent  maintaining  our  link  resolution  knowledge   base  does  not  make  a  long-­‐term  difference  in  the  link  resolution  quality.     based  on  the  data  we  have  collected,  it  would  appear  that  more  work  needs  to  be  done  if  openurl   is  to  continue  as  a  working  standard.  while  our  data  shows  that  direct  linking  offers  improved   service  for  the  user  as  an  immediate  reward,  we  do  feel  some  concern  about  the  longer-­‐term  effect   of  closed  and  proprietary  access  paths  on  the  broader  scholarly  environment.  from  the  library’s   perspective,  the  trend  to  direct  linking  creates  the  risk  of  vendor  lock-­‐in  because  the  vendor-­‐ created  direct  links  will  not  work  after  the  library’s  business  relationship  with  the  vendor  ends.   an  openurl  is  less  tightly  bound  to  the  vendor  that  provided  it.  this  lock-­‐in  increases  the  cost  of   changing  vendors.  the  emergence  of  direct  links  is  a  two-­‐edged  sword:  users  gain  reliability  but   libraries  lose  flexibility  and  the  ability  to  adapt.   the  impetus  for  improving  openurl  linking  must  come  from  libraries  because  vendors  do  not   have  a  strong  incentive  to  take  the  lead  in  this  effort,  especially  when  it  interferes  with  their   competitive  advantage.  we  recommend  that  libraries  collaborate  more  actively  on  identifying   patterns  of  failure  in  openurl  link  resolution  and  remedies  for  those  issues  so  that  openurl   continues  as  a  viable  and  open  method  for  full-­‐text  access.  with  more  data  on  the  failure  modes   for  openurl  transactions,  libraries  and  content  providers  may  be  able  to  implement  systematic   improvements  in  standardized  linking  performance.  we  hope  that  the  methods  and  data  we  have   presented  form  a  helpful  beginning  step  in  this  activity.   acknowledgement   the  authors  thank  kat  hagedorn  and  heather  shoecraft

varnum and marisha c. kelly information technology and libraries | december 2022 https://doi.org/10.6017/ital.v41i4.16005 from the articles and communications in our december issue, the library technology profession has begun thinking through and reporting on the adaptations and changes wrought by the ongoing (some may say never-ending) covid-19 pandemic. four of the 5 articles in this issue relate to the many ways the pandemic altered how libraries do their work, both behind the scenes and in public. from the tools we use internally for project management to those we provide to our public service colleagues, it seems no aspect of library technology has been untouched. in particular, the seriousness of the challenges caused by interfaces with poor accessibility has been brought to the foreground. a critical component of libraries’ diversity, equity, inclusion, and accessiblity(deia) efforts, ensuring equitable access to all must be at top of mind. when the pandemic led libraries, and education in general, to adapt to largely virtual presentation models, the interactive tools we reached for—products such as padlet, jamboard, and poll everywhere— became de rigeur for establishing two-way interactions with our communities. yet little attention was paid, until now, to the accessibility of those tools. in this issue, “tech tools in pandemictransformed information literacy instruction: pushing for digital accessibility” provides excellent qualitative data to help us understand how well, or poorly, these tools meet accessibility needs. articles • digitization of

https://doi.org/10.6017/ital.v38i1.10992 the current (march 2019) issue of information technology and libraries sees the first of what i know will be many exciting contributions to our new “public libraries leading the way” column. this feature (announced in december 2018) shines a spotlight on technology-based innovations from the public library perspective. the first column, “the democratization of artificial intelligence: one library’s approach,” by thomas finley of the frisco (texas) public library, discusses how his library has developed a teaching and technology lending program around artificial intelligence, creating kits that community members can take home and use to explore artificial intelligence through a practical, hands-on, approach. if you have a public library perspective on technology that you would like to share in a conversational, 1000-1500-word column, submit a proposal. full details and a link to the proposal submission form can be found on the lita blog. i look forward to hearing your ideas. in addition to the premiere column in this series, the current issue includes the lita president’s column from bohyun kim to update us on the 2019 ala midwinter meeting, particularly on the status of the proposed alcts/llama/lita merger, and our regular editorial board thoughts column, contributed this quarter by kevin ford, on the importance of user stories in successful technology projects. articles in this issue cover the topics: improving sitewide navigation; improving the display of hathitrust records in primo; using linked data to create a geographic discovery system; measuring information system project success; a systematic approach towards web preservation; and determining textbook cost, formats and licensing. i hope you enjoy reading the issue, whether you explore just one article, or read it “cover to cover.” as always, if you want to share the research or practical experience you have gained as an article in ital,

paul j. fasana (and others). new york: systems office, the libraries, columbia university, 1969. (final report, project no. 7-1129, u. s. office of education, bureau of research) iii, 50, (53) pp. one opens this report wondering whether circulation of reserve books to readers is included in the computer based system, and assuming that such circulation would have to be handled on-line because the short duration of reserve loans, often on the order of one hour, would not seem to fit well with batch processing. it is soon made clear that on-line circulation was set as a goal of the second phase of the system; only the first phase is described here, though somewhat tantalizingly it is stated that one of the aspects of phase two already developed or experimented with is "a fully operational off-line circulation system." what is reported here, however, in commendable fullness, is a system, called reserves processing, which greatly facilitates the processes of putting books on reserve, taking them off, and producing reference lists. emphasis has been placed on developing a generalized system that can be used in different units of the columbia university libraries, and, with necessary modifications, in other academic libraries. the preferred form of data entry is on-line with an ibm 2741 terminal. other functions (and backup systems for data entry) are off-line; the master reserve file is stored on an ibm 2311 disc pack. one section of the report describes the system for those who are not computer specialists; this includes copies of forms and form letters. other sections give technical documentation, including a flow chart, details of format, and actual listings of four programs written in f level cobol for os/360. the report will be valuable to anyone considering the problem of reserve books; its successor covering phase two will be eagerly awaited by all those interested in circulation as well. foster m. palmer involvement of computers in medical sciences, compiled by k. m. shahid, h. j. vander aa, and l. m. c. j. sicking. amsterdam: swets and zeitlinger, 1969. 227 pp. the compilers of this volume have brought together the significant abstracts of the literature that pertains to the use of the computer in present-day medicine. this volume will serve a valuable purpose for those interested in the computer and its applications in medical sciences as it will give a broad overview of computer usage in medicine and many closely allied fields. as computer uses grow in frequency and diversity, a review of this type becomes increasingly valuable to those interested in the field. 1 ohn a. prior book reviews 321 translations journals; list of periodicals translated cover-to-cover, abstracted publications and periodicals containing selected articles, compiled by mrs. a. s. de groot-de rook. delft: european translations centre, 1970. 44 pp. $2.00. this book is an updated bibliographical list and union catalog intended as a guide to scientific and technical journals in translation. entries, arranged alphabetically by original title, contain bibliographical details, publisher and price. the list includes both current and terminated periodicals (about 400 entries). there are cross references from the translated title to the original title. at the end of each entry selected locations and their holdings are listed. the holdings of national translation centres and/or libraries adhering to the european translation centre are also included. a "list of publishing houses," the agents from which to order, are included along with mailing addresses. there is also a "list of holding libraries" with addresses. only non-western language periodicals for which there are western language verisions are included. no non-western journals that contain western language articles or journals originally published in western languages are included. irene braden hoadley ' proceedings of the 1969 clinic on library applications of data processing, edited by dewey e. carroll. urbana: university of illinois graduate school of library science, 1970. 144 pp. $5.00. the volume contains eleven invited papers presented at the seventh annual clinic on library applications of data processing held april 2730, 1969, at urbana, illinois. as in the preceding volumes in this series, the purpose is to report actual experience in case history form of applications of data processing technology to areas of library operations. the book is a source of information on how particular problems were handled within a particular environment. library operations which receive particular attention are the usual ones: acquisitions, cataloging and circulation. "library networks: cataloging and bibliographic aspects," by ann curran presents actual problems encountered in the development of an operating network as well as many thought-provoking questions. stephen salmon's article on automation of the library of congress card division is very informative. also of interest are two articles dealing with pl/i as a programming language for library applications. several articles are beginning to describe on-line applications of data processing for libraries as well as batch processing and the optimal mixes of both. unlike some of the preceding volumes, this volume has a very fine overali index. there is an error in the name of one of the authors (james b. corbin should b e john b. corbin). no participant discussion is included. kenneth ]. bierman 322 journal of library automation vol. 3/4 december, 1970 techniques of information retrieval, by b. c. vickery. hamden, conn.: archon books, 1970. 262 pp. $11.00. this book is a lucidly written text dealing primarily with manual indexing, and the manual construction of document profiles. there is a wealth of information about classification systems and their use for indexing purposes, and two particularly interesting chapters that give illustrations of some of the work going on at information centers, and of some of the basic concepts arising in systems evaluation, respectively. the present reviewer finds this book difficult to deal with, since the temptation continuously arises to substitute one's own aims for those of the author. to my mind, this book does not deal with the "techniques of information retrieval," as commonly understood. the latter would surely include a thorough description of automatic indexing procedures, automatic classification, on-line search systems, modern storage allocation methods, fast search systems, and so on; and while some of these concepts are mentioned in passing, the reader surely cannot obtain an accurate picture in these areas. rather, the book deals with conventional indexing procedures, and will likely be of value for the conventional training of librarians and documentalists. the text is easy to read, and includes plenty of examples, as well as some examination questions and exercises. still, this reviewer wonders whether a more modem book might not have been published in 1970, particularly if the title includes the phrase "information retrieval." to this question, the author would likely answer (as on page 17) that the: " ... analysis and synthesis of information, though it may be aided by the machine can only be carried out effectively by skilled human labor;" or again (as on page 43) : " ... if we cannot say for certain what is the optimum human selection of index terms in a particular situation, then one cannot evaluate a machine selection." statements such as these are easy to generate, particularly if one is not obliged to furnish any proof for one's assertions. in any case, they serve to illustrate the author's viewpoint and his particular choice of subject matter. to summarize, this text appears to be an excellent introduction to conventional documentation work, with emphasis on manual document analysis and indexing. it does not, unfortunately, give a reasonable preview of the fundamental changes which will inevitably occur in the information and documentation fields over the next ten or twenty years. g. salton lib-mocs-kmc364-20140106083618 170 book reviews basic fortran iv programming, by donald h. ford. homewood, illinois: richard d. irwin, inc., 1971. 254 pp. $7.95. fortran texts are now quite plentiful, so the main question in the reviewer's mind is: what does this book have to offer that no other book has? regrettably the answer must be nothing. there are many other good fortran books available. this has very little to distinguish it. that is not to say that it is not a good book. the quality of the book is good, the text is very readable, and there has been very good attention to the examples and proofreading. the book is suit able for an introductory course, or for self study. it does not go completely into all the features of the language, as these are usually best left to the specific manuals relating to the machines available. the book does bring the student to a level where he will be able to use those manuals and the level where he will need to use those manuals. the book does come to the level necessary for the person who writes his programs with professional assistance. the author has chosen ansi basic fortran iv to be discussed in the book. in particular he relates this to the ibm/360 and 370 computers. this is a common language and is available on most machines with only minor modifications. this was a good choice for the level of book he intended to write, since he didn't want to go into the advanced features of the language. the author goes quickly to the heart of the matter in fortran programming, so that the reader can start using the computer right away. the basic material is well covered and gives a good introduction to the more advanced features which are available on most machines. the examples are well chosen so that they do not require any specialized knowledge ; therefore the emphasis can be put on the programming aspects of the examples. he also has very good end-ofchapter problems, ranging in difficulty from straight repetition of text material to programming problems which will require a considerable amount of individual work. he has a good discussion of mixed mode arithmetic, one of the more difficult topics of fortran to explain. he also has a good discussion of input/output operations, and an explanation of formatting which is very good. this again is a difficult area of the language and has been well explained. discussing each of the statement types in fortran, he begins by giving the general form of the statement in a standardized way, which is very good for introductory purposes and for review and reference. the index in the book doesn't single these out, so somebody who wanted to use the book as a reference should make a self-index of these particular areas of the book where the general forms and statements are given. this is a good feature of the book. robert f. mathis book reviews 171 films: a marc format; specifications for magnetic tapes containing catalog records for motion pictures, filmstrips, and other pictorial media intended for pro;ection. washington: marc development office, 1970. 65 pp. $0.65. this latest format issued by the marc development office is similar in organiza tion to the previously issued formats, describing in tum the leader, record directory, control fields , and variable fields. three appendices give the variable field tags , indicators, and subfield codes applicable to this format , categories of films , and a sample record in the marc format. in addition to the motion pictures and filmstrips specified in the subtitle, the coverage of this format includes slides, transparencies, video tapes, and electronic video recordings. data elements describing these last two have not been defined completely as the marc development office feels that further investigation is needed in these areas. the bibliographic level for this format is for monograph material, i.e., material complete at time of issue or to be issued in a known number of parts . since most of the material covered by this format is entered under title, main entry fields ( 100, 110, 111, 130 ) have not been described. this exclusion also covers the equivalent fields in the 400s and 800s. main entry and other fields not listed in this format but required by a user can be obtained from books: a marc format. this format describes two kinds of data: that generally found on an lc printed card and that needed to describe films in archival collections. only the first category will be distributed in machine readable form on a regular basis. one innovation introduced in this format that can only be applauded by marc users is the adoption of the bnb practice of using the second indicator of title fields (241, 245, 440, 840, but not 740 where the second indicator had previously been assigned a different function) to specify the number of characters at the beginning of the entry which are to be ignored in filing. it is to be hoped that in the future this practice will be applied to books, serials, and other types of works as well as to films. judith hopkins u.k. marc pmiect, edited by a. e. jeffreys and t. d. wilson. newcastle upon tyne: oriel press, 1970. 116 pp. 25s. this volume, which reports the proceedings of a conference on the u.k. marc project held in march 1969, may be of as much interest in the usa as in britain; although the intake of british libraries is much smaller and the money available for experiments much less, the problems of developing and using marc effectively within these constraints are for this very reason of special interest. 172 journal of library automation vol. 4/3 september, 1971 a. j. wells opened the conference with a paper introducing u.k. marc and closed it with a paper stating its relationship to the british national bibliography. points of interest are the need for standardisation among libraries (not smprisingly, this theme occurs throughout) and the differences between u.k. marc and l.c. marc (the latter being the odd one out, in its departures from aacr 67). disappointingly, no hint is given of additional national bibliographical products that might come from marc, such as cumulated and updated bibliographies on given subjects, or listings of children's books, etc. richard coward, with his usual clarity and conciseness, explains the planning and format of u.k. marc, in which he has been so centrally involved. as he says, "we have the technology to produce a marc service but we really need a higher level of technology to use it at anything like its full potential." r. bayly's paper on "user programs and package deals" is disappointing, dealing only with icl 1900 computers, and not comprehensively or clearly even with them. two papers discuss the problems of actually using marc: e. h. c . driver's "why marc?", which concludes that "the most efficient use of marc will be made by large library sys tems or groups of libraries," and f . h. ayres' "marc in a special library environment," which concludes that eventually all libraries will use the marc tape. mr. ayres discusses the proposed use of marc at a wre aldermaston, and also gives a general (and highly optimistic ) blueprint of the sort of way marc could be used in an all-through selection, acquisition and cataloging system. (the four american experimental uses of marc reviewed by c. d. batty-at toronto, yale, rice and indianaare probably well enough known in the usa and canada.) keith davidson's discussion of filing problems is first class-and his paper is just as topical as when it was written, because little progress has been made since then. peter lewis, in "marc and the future in libraries," makes the point that whereas bnb cards provided a ready-made product for libraries, marc tapes will merely offer them a set of parts to put together themselves. of special interest to american audiences may be derek austin's paper, "subject retrieval in the u.k. marc," since the precis system to which it forms an introduction may represent a major breakthrough in machine manipulable subject indexing. marc and its uses constitute one of the most rapidly developing areas of librarianship. regular conferences of this standard are needed to review progress from time to time. maurice b. line editorial board thoughts | dehmlow 103 i n the age of the internet, google, and the nearly crushing proliferation of metadata, libraries have been struggling with how to maintain their relevance and survive in the face of shrinking budgets and misinformed questions about whether libraries still provide value. in case there was ever any question, the answer is “of course we do.” still, an evolving environment and changing context has motivated us to rethink what we do and how we do it. our response to the shifting environment has been to envision how libraries can provide the best value to our patrons despite an information ecosystem that duplicates (and to some extent replaces) services that have been a core part of our profession for ages. at the same time, we still have to deal with procedures for managing resources we acquire and license, and many of the systems and processes that have served us so well for so many years are not suitable for today’s environment. many have talked about the need to invest in the distinctive services we provide and unique collections we have (e.g., preserving the world’s knowledge and digitizing our unique holdings) as a means to add value to libraries. there are many other ways libraries create value for our users, and one of the best is for us to respond to needs that are specific to our organizations and users— specialized services, focused collections, contextualized discovery, all integrated into environments in which our patrons work, such as course management systems, google, etc. the library market has responded to many of our needs with ermss and next-generation resource management and discovery solutions. all of this is a good start, but like any solution that is designed to work for the greatest common denominator, they often leave a “desired functionality gap” because no one system can do everything for everyone, no development today can address all of the needs of tomorrow, and very rarely do all of the disparate systems integrate with each other. so where does that leave libraries? well, every problem is an opportunity, and there are two important areas that libraries can invest in to ensure that they progress at the same pace as technology, their users, and the market: open systems that have application programmer interfaces (apis), and programmers. apis are a means to access the data and functionality of our vended or opensource systems using a program as opposed to the default interface. apis often take the shape of xml travelling in the same way that webpages do, accessed via a url, but they also can be as complex as writing code in the same language as the base system, for example software development kits (sdks). the key here is that apis provide a way to work with the data in our systems, be they backend inventory or front-end discovery interfaces, in ways that weren’t conceived by the software developers. this flexibility enables organizations to respond more rapidly to changing needs. no matter which side of the opensource/vended solution fence you sit on, openness needs to be a fundamental part of any decision process for any new system (or information service) to avoid being stifled by vendor or open-source developer priorities that don’t necessarily reflect your own. the second opportunity is perhaps the more difficult one given the state of library budgets and that the resources that are needed to hire programmers are higher than most other library staff. but having local programming skills easily accessible will be vital to our ability to address our users’ specific needs and change our internal processes as we need to. i think it is good to have at least one technical person who comes from an industry outside of libraries. they bring knowledge that we don’t necessarily have and fresh perspectives on how we do things. if it is not possible to hire a programmer, i would encourage technology managers to look closely at their existing staff, locate those in the organization who are able to think outside of the box, and provide some time and space for them to grow their skill set. i am not so obtuse as to suggest that anyone can be programmer—like any skill it requires a general aptitude and a fundamental interest—but i am a self-taught developer who had a technical aptitude and an strong desire to learn new things, and i suspect that there are many underutilized staff in libraries that with a little encouragement, mentoring, and some new technical knowledge, could easily work with apis and sdks, thereby opening the door for organizations to be nimble and responsive to both internal and external needs. i recognize that with heavy demands it can be difficult to give up some of these highly valued people’s time, but the payoff is overwhelmingly worth it. these days i can only chuckle at the doomsday predictions about libraries and the death of our services— google’s dominance in the search arena has never really made me worried that libraries would become irrelevant. we have too much that google does not, specifically licensed content that our users desire, and we have relationships with our users that google will be incapable of having. i have confidence that what we have to offer will be valuable to our users for some time to come. however, it will take a willingness to evolve with our environment and to invest in skill sets that come at a premium even when it is difficult to do so. mark dehmlow editorial board thoughts: adding value in the internet age— libraries, openness, and programmers mark dehmlow (mdehmlow@nd.edu) is digital initiatives librarian, university of notre dame, notre dame, indiana. editorial i think that writing editorials in my job as the new editor of information technology and libraries (ital) is going to be a real piece of cake. all i have to do, dear readers, is to quote (with proper attribution) walt crawford, the title of whose book i repeat as the title of this, my inaugural editorial.1 and then quote other sages of our profession, using only as many of their words as is fitting and proper to make my editorials relevant to the concerns of our membership and readers and as few of my own words as i can to repay the confidence that the library information and technology association (lita) has placed in me— and to avoid muddling the ideas of those to whom i shall be indebted. those of you reading this will note that i have already fallen prey to the conceit of all scholarly journal editors: that their readers, of course, after surveying the tables of contents, dive wide-eyed first into the editorials. of course. to paraphrase a technologist of an earlier era, “when in the course of human events, it becomes necessary for” a new editor to take on the responsibility for the stewardship of ital, “a decent respect to the opinions of mankind requires that” he “should declare the causes which impel” him to accept that responsibility and, further, to write editorials. i quote, of course, from the first paragraph of the declaration of independence adopted by the “thirteen united states of america” july 4, 1776. in this, my first editorial, i, too, shall put forth for the examination of the members of lita and the readers of ital my goals and hopes for the journal that i am now honored to lead. these goals and hopes are shared by the members of the ital editorial board, whose names appear in the masthead of this journal. ital is a double-blind refereed journal that currently has a manuscript acceptance rate of 50 percent. it began in 1968 as the journal of library automation (jola), the journal of the information science and automation division (isad) of ala, and its first editor was fred kilgour. in 1978 isad became lita, and in 1982, the journal title was changed to reflect the expanding role of information technology in libraries, an expansion that continues to accelerate so that ital is no longer the only professional journal within ala whose pages are now dominated by our accelerating use of information technologies as tools to manage the services we provide our users and as tools we use ourselves to accomplish our daily duties. i write part of this editorial in the skies over the middle section of the united states as i return home from the seventh national lita forum held in st. louis, october 7–10. at the forum, i heard presentations, visited poster sessions, and talked with colleagues from forty-four states and six countries who had something to say and said it well. i hope that some of them may submit manuscripts to ital so that all the members of lita and all the readers of the journal will profit as well from some of what the attendees of the forum heard and saw. i attended the forum forewarned by previous ital editors to carry plenty of business cards, and i went armed with a pocketful. i think i distributed enough that, if pieced together, their blank sides would provide sufficient writing space for at least one manuscript! in an attempt to fulfill the jeffersonian promise above, i hereby list a few of my goals for the beginning of my term as editor. i must emphasize that these goals of mine supplement but do not supplant the purposes of the journal as stated on the first page and on the ital web site (www.ala.org/lita/litapublications/ital/italinformation. htm); likewise, they do not supplant the goals of my predecessors. in no particular order: i hope to increase the number of manuscripts received from our library and information schools. their faculty and doctoral students are some of the incubators of new and exciting information technologies that may bear fruit for future library users. however, not all research turns up maps on which “x marks the spot.” exploration is interesting, even vital, for the journey, for the search itself, and our graduate faculties and students have something to say. i hope to increase the submission of manuscripts that describe relevant sponsored research. in the earlier volumes, jola had an average of at least one article per issue, maybe more, describing the results of funded research. ital can and should be a source that information-technology researchers consider as a vehicle for the publication of their results. two articles in this issue result from sponsored research. in fact, i hope to increase the number of manuscripts that describe any relevant research or cutting-edge developments. much of the exploration undertaken by librarians improving and strengthening their services involves research or problems solved on both small scales and large. neither the officers of lita, the referees, the readers, nor i are interested in very many “how i run my library good” articles. we all want to read a statement of the problem(s), the hypotheses developed to explore the issues surrounding the problem(s), the research methods, the results, the assessment of the outcomes, and, when feasible, a synthesis of how the research methods or results may be generalized. i hope to increase the number of articles with multiple authors. libraries are among society’s most cooperative institutions and librarians, members of one of the most cooperative of professions. the work we do is rarely that of solitary performers, whether it be research or the editorial | webb 3 editorial: first have

if other schools are also requiring basic it skills prior to entry, how do those required by slis compare? so i thought i’d do a little investigating to see what others in “library school land” are doing. before i continue, a word of warning: this was by no means a rigorous scientific investigation, but rather an informal survey of the landscape. i started my investigation with ala’s directory of institutions offering accredited master’s programs.2 there are fifty-seven institutions listed in the directory. i visited each institution’s website and looked for pages describing technology requirements, computer-competency requirements, and the like. if i wasn’t able to find the desired information after fifteen or twenty minutes, i would note “nothing found” and move on to the next. in the end i found some sort of list of technology or computer-competency requirements on thirty-three (approximately 58 percent) of the websites. it may be the case that such a list exists on other sites and i didn’t find it. i should also note that five of the lists i found focus more on software and hardware than on skills in using said software and hardware. even considering these conditions, however, i was somewhat surprised at the low numbers. is it simply assumed that today’s students already have these skills? or is it expected that they will be picked up along the way? i don’t claim to know the answers, and discovering them would require a much more detailed and thorough investigation, but they are interesting questions nonetheless. once i had found the requirements, i examined them in some detail to get a sense of the kinds of skills listed. while i won’t enumerate them all, i did find the most common ones to be similar to those required by slis— basic comfort with a personal computer and proficiency with word processing and presentation software, e-mail, file management, and the internet. a few (5) schools also list comfort with local systems (e-mail accounts, online courseware, etc.). several (7) schools mention familiarity with basic database design and functionality, while a few (5) list basic web design. very few (3) mention competency with security tools (firewalls, virus checkers, etc.), and just slightly more (4) mention familiarity with web 2.0 tools like blogs, wikis, etc. while many (14) specifically mention searching under basic internet skills, few (7) mention proficiency with opacs or other common information tools such as full-text databases. interestingly, one school has a computer programming requirement, with mentions of specific acceptable languages, including c++, pascal, java, and perl. but this is certainly the exception rather than the rule. i was encouraged that there seems to be a certain agreement on the basics. but i was a little surprised at the relative rarity of competency with wikis and blogs and all those web 2.0 tools that are so often used and talked about in today’s libraries. is this because there is still some uncertainty as to the utility of such tools in libraries? or is it because of a belief that the members of the millennial or “digital” generation are already expert in using them? i don’t know the reasons, but it is interesting to ponder nonetheless. i was also surprised that a level of information literacy isn’t listed more often, particularly given that we’re talking about slis programs. i do know, of course, that many of these skills will be developed or enhanced as students work their way through their programs, but it also seems to me that there is so much other material to learn that the more that can be taken care of beforehand, the better. librarians work in a highly technical and technological environment, and this is only going to become even more the case for future generations of librarians. certainly, basic familiarity with a variety of applications and tools and comfort with rapidly changing technologies are major assets for librarians. in fact, ala recognizes the importance of “technological knowledge and skills” as core competencies of librarianship. specifically mentioned are the following: ■■ information, communication, assistive, and related technologies as they affect the resources, service delivery, and uses of libraries and other information agencies. ■■ the application of information, communication, assistive, and related technology and tools consistent with professional ethics and prevailing service norms and applications. ■■ the methods of assessing and evaluating the sharon farnel editorial board thoughts: system requirements sharon farnel (sharon.farnel@ualberta.ca) is metadata & cataloguing librarian at the university of alberta in edmonton, alberta, canada. 170 information technology and libraries | december 2010 references 1. university of alberta school of library and information studies, “degree requirements: master of library & information studies,” www.slis.ualberta.ca/mlis_degree_requirements.cfm (accessed aug. 5, 2010). 2. american library association office for accreditation, “library & information studies directory of institutions offering accredited master’s programs 2008–2009,” 2008, http:// ala.org/ala/educationcareers/education/accreditedprograms/ directory/pdf/lis_dir_20082009.pdf (accessed aug. 5, 2010). 3. american library association, “ala’s core competences of librarianship,” january 2009, www.ala.org/ala/education careers/careers/corecomp/corecompetences/finalcorecomp stat09.pdf (accessed aug. 5, 2010). specifications, efficacy, and cost efficiency of technology-based products and services. ■■ the principles and techniques necessary to identify and analyze emerging technologies and innovations in order to recognize and implement relevant technological improvements.3 given what we know about the importance of technology to librarians and librarianship, my investigation has left me with two questions: (1) why aren’t more library schools requiring certain it skills prior to entry into their programs?

the cloud faces many more constraints than industrial light & magic (ilm). nevertheless, we found a way to achieve a form of virtual production in our space now, as the tools have become quite accessible compared to even a few years ago. base station nikon d5600, camera that captures our actor. vive tracker, used in conjunction with the base station to sync the location and rotation of our physical camera with our virtual camera increasingly accessible tools on the software side we rely on blender for creating virtual environments and we use unreal engine 5 for the virtual production logic and rendering. both software applications are used in professional film production and both are completely free. in fact, the virtual production stage used in the mandalorian also relies on unreal engine. thanks to the gaming and live streaming industries, the hardware required has become much more affordable. in our production we acquired the latest graphics and vr tracking equipment for a few thousand dollars. such equipment includes our workstation laptop for running unreal engine and the htc vive 3.0 tracking system for synchronizing the position and orientation of our physical camera with our virtual camera. for a full breakdown, refer to the documentation on our project’s github page. https://www.vive.com/us/accessory/base-station/ https://www.nikonusa.com/en/nikon-products/product/dslr-cameras/d5600.html https://www.vive.com/us/accessory/tracker3/ https://github.com/dp-mason/budget-virtual-production information technology and libraries march 2023 virtual production at cloud901 3 mason and ji our approach the process used by ilm begins with the render of the environment in unreal engine, which is then sent to the led-panels surrounding the stage, which light the stage and act as the backdrop that the camera captures. the actors on the stage are working with the same visual backgrounds and lighting that will ultimately be seen by the viewer at home. (other effects are added in postproduction.) this means that the real actors are illuminated by the virtual background via the led displays, making the addition of purely virtual effects easier and more seamless. example of the cylindrical computer-generated background with actors in the center, lit with the same illumination as is generated by the virtual set. image licensed under the creative commons attribution-share alike 4.0 international license. source: https://commons.wikimedia.org/wiki/file:stagecraft_the_mandalorian.jpg. in contrast, our effects process begins at our physical camera by sending the live video of our actor against a green screen to unreal engine, where the video is processed to remove the background. then, with the help of a virtual object matching the dimensions of our physical green screen, we apply the actor’s image on top of the virtual environment. instead of projecting our virtual environment to real space through led panels, we do the inverse: we project our actor into the virtual environment, achieving a similar effect at a fraction of the cost. https://en.wikipedia.org/wiki/en:creative_commons https://creativecommons.org/licenses/by-sa/4.0/deed.en https://commons.wikimedia.org/wiki/file:stagecraft_the_mandalorian.jpg information technology and libraries march 2023 virtual production at cloud901 4 mason and ji render of our virtual production set. this is what our scene looks like in unreal engine from a view outside the camera. the image of our actor appears distorted from this angle, because it is projected from the camera to a mesh matching our green screen’s dimensions. this is the view of our virtual scene from the camera. source: https://www.blendswap.com/blend/30009 https://www.blendswap.com/blend/30009 information technology and libraries march 2023 virtual production at cloud901 5 mason and ji why does this project matter? the philosophy i had been pursuing photography, music, and 3d graphics since long before i joined cloud901 professionally. this interest actually began in my own teenage years while i was a volunteer at cloud901. at the time i was producing music, learning more about cameras through event photography, and just beginning to create 3d animations in blender. when i left for college to study computer science, i still had these interests, but they sometimes took a back seat to my studies. as time went on, though, i began to see how these interests and art in general are not incompatible with computer science. there are many ways to exemplify this compatibility, but there is something special about virtual production in particular. many students new to computer science get the impression that the field is all about memorizing rigid rules so that you can arrive at a “correct” solution. it is natural to feel that way even after months of classes. while it is true that creating in this medium can feel restricting, it offers many opportunities to make creative contributions. computer programming—especially in the context of virtual production—is like lute-making. a luthier’s first lutes are likely very ordinary, much of their effort spent attaining the “correct” sound in their instruments. yet, if they continue to develop their technical ability, to learn the mechanics of producing sound, and to become more comfortable with experimentation, they can influence the future of music in an aesthetic way without necessarily conforming to rigid notions of “correctness.” such an opportunity presented itself during the rise of opera. luthiers of the late sixteenth century used their technical knowledge to create the theorbo and other adaptations of the lute that would not be drowned out by an opera singer. there is nothing “correct” or “incorrect” about the theorbo or about virtual production methods, but rather they are subjective visions of how film production and music can adapt to create new experiences. virtual production is a fascinating use of current technology; it leverages current computing power to innovate in a field not typically associated with computer science. it makes us wonder what other industries could benefit from the application of programming. using lessons i taught students about unreal engine, i encouraged them to embrace topics such as programming, linear algebra, and photography as knowledge essential to crafting their own “instruments.” this began with smaller projects such as a creating a cube that moves up and down according to a sine wave and progressed to building extensions for the system we use to calibrate our camera tracking. co-author alan ji first got into 3d graphics through a programming camp at the memphis public library over the summer. it was there that he met david, and there that he was introduced to unreal engine. it’s crazy to think that i went from not knowing anything about unreal engine to helping create a virtual production set in a few months. connecting to the outside the novelty of this project also forged connections with people outside of the library. spencer burnham, a project manager critical to some of the biggest xr experiences to date, such as bafta award-winning app “wonderscope,” visited cloud901 to discuss his career and the potential he sees in learning virtual production to the cohort of youth interested in contributing to our project. while demoing the project at the “cs for all” conference last fall, i spoke to a computer science information technology and libraries march 2023 virtual production at cloud901 6 mason and ji teacher at a local high school and later spoke to the students in his after-school program. the debut of cloud901’s virtual production studio features a performance from alfred banks, a regularly touring vocal performer from new orleans. next steps in the short term, we would like to make our system easier to use and share it via an open source license. the current version of our system is hosted and documented on github. in the long term, we plan to take a more formal approach to onboarding youth contributors during the summer and record regular performances. currently we have onboarded people to the project on an ad-hoc basis, but we plan to organize regular summer programming teaching students interested in film and programming how to use and extend this program. we plan to use this set to host a series of performances featuring established musicians from the area. this will provide our youth contributors with practical experience working on an innovative form of production and opportunities to network with established creatives. external links • github repository for our project • our proof of concept video • cloud901 home page https://github.com/dp-mason/budget-virtual-production https://youtu.be/evbbt_uzhde https://youtu.be/evbbt_uzhde https://www.memphislibrary.org/cloud901/ background cloud901 virtual production how can we do this?

( 1) libraries are not beds-but the images are revealing and useful. that there is an information explosion going on, we are told too often by the impatient. and the very grammar of the situation reassures us: unlike tristan and isolda or a bomb, the information explosion can never explode or be exploding. for all its information (or is it just the patterns and inscriptions of a nominalist?) the library is so mundane it hardly merits a peeping tom. the information needs of the dons are seldom met by the library. unmythical mortals, however, swear by the local branch. the repositories of effable library data are small-and still far from full or accurate. perhaps most surprising is that information processing machines are still essentially foreigners in the repositories of information. and that is incredible. given this background i would like to make a suggestion based on some ideas from computer processing with a very mundane practicability -a workable compromise between the catalog and the possible computer manipulation in n dimensions. i take it that the "linearity of the catalogue" cataloging geometry /hazelton 13 is an abstraction; " .. . linearity is dictated by the physical form of the book and the characteristics of library architecture. in effect, a library is one continuous shelf of books, and each particular book represents a speciflc point in that line. it must follow, therefore, that any classification that can be applied to such an assemblage of units must necessarily exhibit a linear sequence of its terms." ( 2) the crucial words are "in effect." few libraries are in fact one continuous shelf. i know of one-it is my daughter's and suffers from a long shelf and only thirty-seven volumes. both the best and the worst of this view are exhibited as it is pushed to the extreme: "the failure of our present systems of book classification in no way condemns the act of classification as a fundamental bibliographic technique. book classification, as we have used it in the past, has failed for two reasons: one, because it has been based upon the book as a physical entity without taking into consideration the inherent character of the book as a composite intellectual product; two, because of limitations arising from the properties of our hierarchical systems of classification. jevons was right, for library classiflcation as he knew it, was indeed "a logical absurdity." by this he meant, of course, that the content of books is polydimensional, which is logically incompatible with the traditional hierarchical schematization of knowledge, which is a linear progression from general to specific. the book, then, as a physical unit, and irrespective of the dimensions of its content, must be forced into a monodimensional system in which it has only linear position. this limitation alone destroys most of the utility of traditional book classifications as instruments for the effective subject organization of library materials." ( 3) the best is this i think-the current schemes are inadequate and one of the major limitations is the notion that each book must be classified only as a linear position. more generally, this idea of linearity points to the absurdity in classification schemes. and now the worst-linearity is not just an abstraction; it is a myth and a fraud. it has not adequately represented the book as a physical object and has been constrained by the error, not the book. let us look more closely at the geometry of the book. that aspect apparently most startling to the classificationist (but not the librarian who never has enough room) is its solidity-its three dimensionality. it is impossible to build a book of less than three dimensions! the same problem exists for unmythical libraries-three dimensions are essential. practice does not easily square with the theory of one-dimensional libraries. the points on the line are far more arbitrary than you imagine. why does that line start on floor one, jump to three, back to one, up to two, and die in the basement? and having traversed the line, we will usually not have found any newspapers, any fiction , any children's books, and few journals. does that line ever flash through the shelf of brightly colored new books resplendent in the lobby impressing the children and trustees? 14 ]ourrujl of library automation vol. 5/1 march, 1972 allow the line to run through every shelf now. what most characterizes the scheme? for all the complexities, for all the work of dewey, la fontaine, and ranganathan, it is simplicity! books about the same subject or in some congenial category are insofar as possible physically proximate. by congenial category i mean a grouping according to a concept which is not a subject classification. the difficulty encountered in one dimension is purely physical. logically, any finite number of dimensions can be mapped into the integers ( i.e., one dimension) as long as the members of each dimension set are denumerable. ordered pairs are easily mapped into the integers by the following formula: i(x, y)=% (x+y)~+3x+y. this yields the progression of pairs < 0, 0 > , < 0, 1>, <1, 0>, < 0, 2>, < 1, 1> , <2, 0 >, < 0, 3>, < 1, 2>, etc. ordered triples are ordered pairs of ordered pairs and the integers: t(x, y, z)=i(x, i(y,z) ). and so on. because we have a d enumerable set of books we can accomplish a linear mapping by both subject and category. in fact , the problem is trivial because there are only a finite number of books. physically, however, neither subject nor category will remain together. to suit the library the mapping must be physically simple, but can be abstractly complex. for all his protestations, the classificationist cannot eschew the physical library. if he could-or wished to-the way is open. as i understand classification, it is vacuous without reference to its ability as a finding tool. it must concern itself with the polydimensional aspect of content but cannot disregard the codex. in answer to the question form "where is the book about ... ?" an appropriate and total response type is "at location (x, y, z) ." here x, y, and z are the spatial coordinates relative to a particular library both as to origin and values. the dewey or lc numbers of the book are incomple te answers in that they presume a knowledge of the classification structure as well as knowledge of the architecture of the building. i have suggested that a classification scheme must not disregard the codex, but must insofar as possible not be subservient to physical form. the following scheme takes advantage of the codex form, is as easily automated or computerized as current one-dimensional schemes, advances beyond one dimension, and is very relevant to finding: a library is considered as a three-dimension entity. conventions are adopted for run-on from room to room and floor to floor as for the linear scheme. each book is classified in all three dimensions-the dimensions being independent. the interpretation of each dimension is left to the discretion of the individual library. thus each book has a relative position in each dimension. (this is not an alexandrian scheme relying on absolute location. ) the following example illustrates the relevant concepts: choose a subject classification (as commonly understood ) for the x dimension. for example, let dewey numbers be arranged from left to right on the x axis. choose a category scheme for the y dimension. one could assign degrees of difcataloging geometry/hazelton 15 x d i f f i c u subject ficulty from one to seven, for example. choose a category scheme for the z dimension. one could assign numbers between one and seven running from most general to most specific. this has the following effect: standing in front of the near shelf (i.e., z=l) one can choose a subject by moving laterally. the general books will appear first with difficult items at the top, easy ones at the bottom. if the items are too general, merely move one stack forward and try again. this approach presents an unusually usable instructional layout for circular libraries. a reading lounge can be put dead center with the most subject specific books ranged about the circumference. level of difficulty is easily adjusted by looking up or down. given this apparatus you may wish to change the subject classification scheme. why not put solid state physics behind general physics instead of to the right or left? the card catalog can now be used with greater meaning. there is no reason why it cannot be a map of the shelves. the axes can be translated for ease of searching (e.g., interchange x and y for the card catalog). of particular interest is the relation between this scheme and those of a. d. booth ( 4) where access time is minimized by arranging books in the inverse order of their frequency of use. further refinements consider nonstandard shelf layouts (radial, circular, spiral). one misgiving about shelving by inverse frequency expressed by librarians is that one no longer knows where to look for a particular book in the sense that one knows when using standard schemes. this objection is easily overcome by combining the three-dimensional and frequency schemes. one dimension can be used for frequency, leaving two dimensions in which to group books by subject, difficulty, generality, color, length, or whatever you please. access time is reduced while physical grouping is retained. 16 journal of library automation vol. 5/1 march, 1972 one difficulty that will be encountered is the classification of books that are not subject-oriented-poetry and fiction, for example. these areas are not adequately dealt with in linear schemes and they could easily be left as they are. that is, two dimensions could be constants. on the other hand, it seems plausible that, given three dimensions in which to work, someone could discover congenial physical groupings that would be reasonable yet impossible in one dimension. rather than being a problem, threedimensional classification offers opportunities to cope with literatures that are not subject specific. each dimension of this scheme can be criticized on the same grounds as the current linear classification. but, taken as a whole, it provides a more powerful, much needed tool for the classificationist while allowing new approaches by automaters. its simplicity is assured because it is closer to our intuitive notions of information storage. three dimensions are necessary! references 1. w. h. auden, "the cave of nakedness," about the house ( new york: random house, 1965), p.32. 2. jesse h. shera, "classification-current functions and applications to the subject analysis of library material," in libraries and the organization of knowledge (connecticut: archon books, 1965), p.97 -98. 3. jesse h. shera, "classification as the basis of bibliographic organization," in libraries and the organization of knowledge (connecticut: archon books, 1965) , p.84, 85. 4. a. d. booth, "on the geometry of libraries," journal of documentation 25:28-42 (march 1969). lib-s-mocs-kmc364-20141005044532 156 corporate author entry records retrieved by use of derived truncated search keys alan l. landgraf, kunj b. rastogi, and philip l. long, the ohio college library center. an experiment was conducted to design a corporate author index to a large bibliographic file. the nature of corporate entries necessitates a different search key construction from that of personal names or titles. derivation of a search key to select distinct corporate entry rec01'ds is discussed. introduction this paper describes the findings of an experiment conducted to design a corporate author index to entries in a large file of catalog records at the ohio college library center; a companion paper describes findings of a similar investigation into retrieval employing a personal author index. 1 the center has operated an on-line, shared cataloging system since august 1971. in addition to a library of congress card number index, the system maintains truncated name-title and title index files. the user is thus able to retrieve entries employing truncated search keys. three previous papers report results of experiments which led to the design of the name-title and title indexes.24 for monographs having personal names as main entries, a truncated 3,3 search key consisting of the first three letters of the author's name plus the first three letters of the first non-english-article word of the title was judged to be satisfactory in that this key yielded five or fewer entries per query in more than 99 percent of the cases when keys were selected at random.5 however, a recent study by guthrie and slifko reveals that a model which employs random selection of entries yields results closer to actual experience, and with a higher average number of entries per reply.6 a search key composed of the first five or four characters of the surname and the first or first and second initials makes possible efficient retrievap however, the situation is different in the case of corporate entries because many corporate names begin with the same or similar words. for example, in the records examined, the initial words of more than 1,300 publications are "u.s. congress, house committee on .. .. " obviously a corporate author entry recordsjlandgraf, et al. 157 type of search key different from that which proved efficient for retrieving personal authors is required for retrieval of corporate entries. material and methods the experiment used a file of approximately 200,000 marc ii records having a total of 68,169 corporate name entries. corporate entries were extracted from the llo, ill, 410, 411, 710, 711, 810, and 811 fi elds in the records. a program edited the file to extract keys; initial english language articles were removed from each entry, and the words "united states," "u.s .," "u. s.," "great brit.," and "great britain" appearing anywhere in the entry were replaced with "us" and "gt brit" respectively. a blank was substituted for each subfield delimiter and associated code, and unwanted characters such as punctuation, diacritics, and special symbols were removed; the program also closed up the space that the unwanted character had occupied. one blank replaced multiple blanks. the elements extracted consisted of five segments of eight characters each, representing the initial eight characters of the first five words of the corporate entry. segments containing fewer than eight characters were padded out with blanks. if a corporate name had fewer than five words, the remaining segments were blank. to study a given type of key, the file was sorted on a specified number of initial characters of each segment; these initial characters were then employed as search keys by a program which sequentially compared the characters in the key, counting distinct and identical keys. results and discussion table 1 presents the number of distinct keys and the maximum number of occurrences of identical keys for the structures studied in the experiment. the larger the number of distinct keys for a fixed number of entries in the file, the better the key will be for retrieval purposes. given two search keys which are more or less equally specific, the one which is simpler to use is preferable. the peculiarity of corporate-entry keys can be observed from table 1. even for the 8,8,8)8,8 key structure the percentage of distinct keys ( 33.7 percent) is low, and the maximum number of occurrences of an identical key ( 1304) is high. another observation revealed by table 1 is that as the key structure goes from five to three segments, there is a steady decrease in the percentage of distinct keys and consequently an increase in the maximum number of entries per key. however, a reduction in the number of characters in a segment does not cause a great deal of deterioration. for example, for 8,8,8,~,8 keys, the percentage of unique keys and the maximum number of entries per key are respectively 33.7 percent and 1304, while for 2,2,2,2,2 keys, the corresponding figures are 32.3 percent and 1307. thus, the 2,2,2,2,2 key structure seemed a good candidate for a corporate 158 journal of library automation vol. 6/ 3 september 1973 table 1. number of

number of entries per reply for this key structure was more intensely studied. on the average it is desirable that the number of replies per query be such that information by which the user can choose among the possible replies can be displayed on a single crt screen. this maximizes the utility of a computer system, since it minimizes the amount of system activity to promptly satisfy a user's request. since some query keys produce but one reply while others produce hundreds of candidate records, it is necessary to use the mathematics of probability to determine the likely long-term effect of a given choice of system parameters. using the approach indicated table 2. average number of entries per reply for key st1·ucture 2,2,2,2,2 for various multiplicity of entries. number of average

becomes the following. assume that every entry has an equal probability of being accessed. then, in attempting to retrieve each entry once, keys having i number . of entries will cause a total of i 2 entries to be accessed. if ft denotes the frequency of keys having i number of entries and m denotes the maximum allowable occurrences of any key in the file, the average number of entries per reply y, is given by: jl{ where ~ i ft is the number of entries in the file whose derived keys have • = 1 a frequency of m or less. the above formula yields the average number of entries per reply for the 2,2,2,2,2 key to be much larger than 20 for m > 100; but some 2,2,2,2,2 keys corresponded to more than 500 file entries. a typical crt display terminal can accommodate only ten or fewer entries per screen. therefore, if the average number of entries per reply is desired to be ten or fewer, it is necessary either to ignore entries with high multiplicity or to adopt a different scheme of storing and retrieving such items, in which case the mathematical result would be the same as ignoring high-frequency items. the average number of entries per reply was computed for five different values of m ( 19,29,39,49, and 59); the results of these computations are in table 2, which reveals that if keys in the file are allowed a maximum recurrence of 39 entries per key, it would be possible to have keys in the main index for about 75 percent of total records, while entries for only 142 high frequency keys would have to be shunted to a secondary index. in this case, the average number of entries per reply would be about eight. table 3 gives the probability of number of entries per reply for the index file consisting of 50,854 (out of a total of 68,169) records with the maximum frequency of any key in the file being 39. for preparing this table the assumption is made that each entry in the file has an equal probability of being accessed. thus the probability of obtaining i entries per reply is given by: p(i)= jft 'f. ifj i= 1 where f, is frequency of keys occurring exactly i number of times in the index file. an inspection of this table shows that in 87.7 percent of the 160 journal

and libraries | june 2008 mark beatty (mbeatty@wils.wisc.edu) is lita president 2007/2008 and trainer, wisconsin library services, madison. mark beattypresident’s message i’ve recently read three quite different articles that surprisingly all had something similar to say with a different twist on the theme uppermost in my brain the last year or two. here’s the briefest of quotes from the three. i would suggest your full reading of all three if you haven’t already. n lankes, silverstein and nicholson, “participatory networks: the library as conversation,” in the december 2007 information technology and libraries: “with their principles, dedication to service, and unique knowledge of infrastructure, libraries are poised not simply to respond to new technologies, but to drive them. by tying technological implementation, development and improvement to the mission of facilitating conversations across fields, libraries can gain invaluable visibility and resources.” n bill crowley, “lifecycle librarianship,” in the april 1, 2008 library journal: “public, academic, and school librarians should adopt the service philosophy of lifecycle librarianship and jointly plan at town, city, or county levels to identify and meet human learning needs from “lapsit to nursing home.”” n joe kissell, “instant messaging for introverts,” in the april 4, 2008 tidbits (http://db.tidbits.com/ article/9544): “several people i discussed this issue with (using im and twitter) expressed dismay at having had relationships deteriorate due to an unwillingness on another person’s part to adapt to changing technology. for example, people who don’t use e-mail don’t get evites, and so they end up being excluded from parties.” what all three express to me is a concern that libraries, and just plain humans, need to be part of the conversation, part of the social structure, and full participants in life. we are now, through surveys and meetings and focus groups, starting to know that new librarians and new lita members are most interested in networking with their colleagues using multiple methods to fulfill the whole range of their professional and social needs. lankes wants to make sure we participate with all our constituencies, crowley wants us to spend a lifetime with those constituencies, and kissell wants to make sure we get invited to the party. that sounds a bit facetious but i believe the point is that our association, our libraries, our social structures are now required to be active participants, physically and virtually, in the life of their communities. we have to recognize our communities and then act to participate and provide space and support to those communities. this takes work and the will to always be part of our communities. all of which leads to my president’s program, featuring keynote speaker joe janes and the blogging folks at “it’s all good” at the ala annual conference 2008 in anaheim, california. it will be part of sunday afternoon with lita, taking place on sunday, june 29, 2008. the program line up will include: n top technology trends 1:30–3:00 p.m. n lita awards and scholarships reception 3–4 p.m. n lita president’s program 4–5 p.m. n “isn’t it great to be in the library . . . wherever that is?” it’s often said that today we have to run three libraries at once: the library of yesterday, today, and tomorrow. we run both the physical, visible library, and the one that exists beyond the walls. this raises many questions of what a library is and encompasses, what it isn’t, where the boundaries lie, the impact on what we do and how we do it, what our clients want, how we serve them, and what kinds of librarians serve them. this program will attempt to examine the full social and cultural constructs of libraries that move beyond basic web 2.0 and integrate patrons, librarians, and resources in what should be a ubiquitous manner. join joe janes, associate professor in the information school of the university of washington in seattle and columnist for american libraries, keynote speaker, along with members of the “it’s all good” blogging group (http://scanblog.blogspot.com) as the reactor panel for a lively exploration of possible futures. i hope you’ll be able to attend but be assured that members of the lita community will blog and report and even record the sessions in various ways that will be made freely available to our community. editorial board thoughts: policy before technology — don’t outkick the coverage editorial board thoughts policy before technology don’t outkick the coverage brady lund information technology and libraries | march 2022 https://doi.org/10.6017/ital.v41i1.14773 brady lund (blund@g.emporia.edu) is a doctoral candidate and lecturer at emporia state university and a member of the ital editorial board. © 2022. opinions expressed in this column are the author’s and do not reflect those of the editorial board as a whole or of core, a division of ala. in the race to adopt the newest and best, practical considerations for emerging technologies are frequently overlooked. technology can set an organization apart and, in the case of libraries, be instrumental in helping demonstrate value. yet, all new technologies carry additional, potentially unpleasant consequences, whether it be threats to privacy and security, barriers to accessibility or risks to health, learning barriers, or exposure to misinformation. organizations must consider these threats before introducing new technologies, rather than the other way around. to illustrate these threats and their policy implications, i will briefly discuss two popular technologies/innovations—virtual reality and data analytics—and the threats that are often overlooked by organizations and how they may be appropriately addressed by policy. virtual reality (vr) has quickly become a popular technology in all types of libraries and learning organizations. as noted in many recent publications, vr provides an immersive and interactive medium to engage with learning and entertainment content.1 of course, libraries are always seeking new ways to engage patrons with their collections and services, so it is natural that there would be high interest in this technology. however, i have observed that this technology is frequently made available with little foresight or oversight of potential issues. the engaging interface of vr technology also presents risks to certain individuals. it has been known to invoke seizures among those who are predisposed and can cause severe dizziness and disorientation.2 these risks are severe enough that the institutional review board at my university required a safety disclaimer be included for any project that utilized vr technology for learning. however, inclusion of a disclaimer is not necessarily common practice in library research and certainly not for non-research projects. further, substantial learning barriers should be acknowledged for virtual reality technology. a learning curve is perhaps a less-serious threat, compared to the health and safety risks, but can still lead to non-use or misuse of the technology.3 libraries should want as many patrons as possible to use the technology to enrich their lives. this includes individuals who have limited technology experience. it is important to provide education and policy to ensure the technology is used properly, such that the technology will not be damaged, and the user will not quit trying to use the technology due to frustration. specific policies for the use of vr technology could be integrated into existing technology policy (if such a policy already exists) or created as a new policy. either way, it should be highly visible, and patrons should be asked to acknowledge it before use. the policy may include elements like that “the patron must follow all library employees’ guidance on how to properly use the vr headset” and “the patron is encouraged to ask any employee for assistance with the headset.” while a library may not be able to foresee or enforce perfect policy for all issues that arise from using emerging technologies like vr, these are some commonsense policy items that protect the user, the library, and the technology while it is in use. though a vastly different “technology” in many ways, the evolution of data analytics in modern libraries similarly poses significant threats to library patrons. as opposed to physical threats to well-being, the threats associated with data analytics are mostly related to social, psychological, and economic well-being mailto:blund@g.emporia.edu information technology and libraries march 2022 policy before technology | lund 2 through privacy and security risks. depending on how data is used, it can be rather innocuous or overtly malicious. it is not always clear when data goes from being innocuous to being a threat.4 collecting patron addresses can seem like necessary and acceptable data in order to issue a library card. libraries could use this data, though, in conjunction with census and other government data, to identify demographics of library users, like the ethnicity of patrons. this could be helpful in knowing, for instance, that a library has a large hispanic patron-base and thus may want to invest in spanish-language resources, but it also involves using data that patrons were forced to supply in order to profile them and make inferences about what materials they would like. understandably, many patrons would likely rather not have private data about them collected and analyzed, even if it could significantly improve services. there is certain data—like the addresses mentioned above—that libraries must collect in order to provide services. this cannot be avoided. rather, what should be done is to have a policy that clearly (without much legal jargon) outlines what data is collected and for what purposes it is used. everyone knows that no one reads lengthy legal disclaimers. while it may be seen as above-board in the eyes of the law, slipping policies that the library knows most patrons would question into a disclaimer is unethical. any questionable policies or procedures should be made clear to patrons, so that they can make an informed decision on whether to opt out of those services. it is great to have extensive data to improve services, but it should not be collected without real consent. no librarian should go home at the end of the day with any question about whether they used proper data collection procedures. additionally, there are always risks with the storage and maintenance of data. how is the data being stored? what security measures have been taken? these questions, along with the concerns in the prior paragraphs, are items that would all have to be addressed in an ethical review application for human subjects research at a university, but could be (and often are) overlooked when it comes to library service s and assessment. this may be particularly true at public libraries, which are not connected to an institution of higher education (which provide some ethical oversight). it is always better to start with a policy than to make one up as one goes along, even if it is necessary to adjust the policy over time as new risks and considerations emerge. for those who are creating a new policy from scratch, one of the best sources of information and inspiration can be the existing policies of other, similar organizations.5 for example, a large public library may look to the data policies of a similarlysituated large public library for inspiration. i encourage additional works by researchers within the field of library technology to strengthen evidence based practice within the area of technology policy formation. it is important to be careful with the design of policy and not to come at it without first doing your homework. yet, at the same time, it is important to consider the unique context of your own institution. what is a successful policy for one library may not be so for another—you must know your service population and specific space and technology infrastructure and management capacities. something like the administrative structure of a library system can significantly impact the success of policy implementation. policy, understandably, can be seen as a boring—if necessary—part of the proper functioning of a library and its technology. this can lead to policy being something that either is created in haste or after considerable procrastination, or something that becomes the subject of unnecessary, prolonged debate among library administration. in most cases, appropriate policy can, in fact, be quite straightforward, if libraries rely upon existing policy examples, understanding of the technology in question, and a thorough assessment of their library environment to guide the policy-drafting process. technology policy can be a boring subject, but its necessity cannot be overstated for reducing liability and threats to the well-being of patrons, library employees, and property. it is important to have technology policy in place before the information technology and libraries march 2022 policy before technology | lund 3 technology is made available to the public so that patrons can make informed decisions about whether to use the technology and/or agree to share data. endnotes 1 matt cook et al., “challenges and strategies for educational virtual reality,”

march_ital_dehmlow.docx editorial  board  thoughts     a&i  databases:  the  next  frontier     to  discover   mark  dehmlow       information  technology  and  libraries  |  march  2015     1   i  think  it  is  fair  to  say  that  the  discovery  technology  space  is  a  relatively  mature  market  segment,   not  complete,  but  mature.    much  of  the  easy-­‐to-­‐negotiate  content  has  been  negotiated,  and  many   of  the  systems  on  the  market  are  above  or  approaching  a  billion  records.    this  would  seem  a  lot,   but  there  is  a  whole  slice  of  tremendously  valuable  content  still  not  fully  available  across  all   platforms,  namely  the  specialized  subject  abstracting  and  indexing  database  content.    this  content   has  a  lot  of  significant  value  for  the  discovery  community—many  of  those  databases  go  further   back  than  content  pulled  from  journal  publishers  or  full-­‐text  databases.    equally  as  important  is   that  they  represent  an  important  portion  of  humanities  and  social  sciences  content  that  is  less   represented  in  discovery  systems  as  compared  to  stem  content.    for  vendors  of  a&i  content,  the   concerns  are  clear  and  realistic,  differently  from  journal  publishers  whose  metadata  is  meant  to   direct  users  to  their  main  content  (full  text),  the  metadata  for  a&i  publishers  is  the  main  content.     according  to  a  recent  nfais  report,  a  major  concern  for  them  is  that  if  they  include  their  content   in  discovery  systems,  they  “risk  loss  of  brand  awareness”  and  the  implications  are  that  institutions   will  be  more  likely  to  cancel  those  subscriptions.1    the  focus  therefore  seems  to  have  been  how  to   optimize  the  visibility  of  their  content  in  discovery  systems  before  being  willing  to  share  it.       in  addition  to  the  nfais  report,  some  of  the  conversations  i  have  seen  on  the  topic  seem  to  focus   on  wanting  discovery  system  providers  to  meet  a  more  complex  set  of  requirements  that  will   maximize  leveraging  the  rich  metadata  contained  in  those  resources,  the  idea  being  that  utilizing   that  metadata  in  specific  ways  will  increase  the  visibility  of  the  content.    in  principle  i  think  it  is  a   commendable  goal  to  maximize  the  value  of  the  comprehensive  metadata  a&i  records  contain,   and  the  complexities  of  including  a&i  data  into  discovery  systems  need  to  be  carefully  considered   -­‐  namely  blending  multiple  subject  and  authority  vocabularies,  and  ensuring  that  metadata   records  are  appropriately  balanced  with  full  text  in  the  relevancy  algorithm.  but  i  also  worry  that   setting  too  many  requirements  that  are  too  complicated  will  lead  to  delayed  access  and  biased   search  results.    it  is  important  that  this  content  is  blended  in  a  meaningful  way,  but  determining   relevancy  is  a  complex  endeavor,  and  it  is  critically  important  for  relevancy  to  be  unbiased  from   the  content  provider  perspective  and  instead  focus  on  the  user,  their  query,  and  the  context  of   their  search.       another  concern  that  i  have  heard  articulated  is  that  results  in  discovery  services  are  unlikely  to     be  as  good  as  native  a&i  systems  because  of  the  already  mentioned  blending  issues.    this  is  likely     mark  dehmlow  (mark.dehmlow@nd.edu),  a  member  of  the  ital  editorial  board,  is  program   director,  library  information  technology,  university  of  notre  dame,  south  bend,  in.       editorial  board  thoughts:  a&i  databases  |  dehmlow     2   to  be  true,  but  i  think  it  is  critical  to  focus  on  the  purpose  of  discovery  systems.    as  donald   hawkins  recently  wrote  in  a  summary  of  a  workshop  called  “information  discovery  and  the   future  of  abstracting  and  indexing  services,”  “a&i  services  provide  precision  discipline-­‐specific   searching  for  expert  researchers,  and  discovery  services  provide  quick  access  to  full  text.”2     hawkins  indicates  that  discovery  systems  are  not  meant  to  be  sophisticated  search  tools,  but   rather  a  quick  means  to  search  a  broad  range  of  scholarly  resources  and  i  think  sometimes  a  quick   starting  point  for  researchers.    because  of  the  nature  of  merging  billions  of  scholarly  records  into  a   single  system,  discovery  systems  will  never  be  able  to  provide  the  same  experience  as  a  native  a&i   system,  nor  should  they.    over  time,  they  may  become  better  tuned  to  provide  a  better  overall   experience  for  the  three  different  types  of  searchers  we  have  in  higher  education:  novice  users  like   undergraduates  looking  for  a  quick  resource,  advanced  users  like  graduate  students  and  faculty   looking  for  more  comprehensive  topical  coverage,  and  expert  users  like  librarians  who  want   sophisticated  search  features  to  hone  in  on  the  perfect  few  resources.    many  of  the  discovery   systems  are  working  on  building  these  features,  but  the  industry  will  take  time  to  solve  this   problem,  and  i  tend  to  look  at  things  from  the  lense  of  our  end  users—non-­‐inclusion  of  this   content  directly  impacts  their  overall  discovery  experience.   one  might  ask,  if  the  discovery  system  experience  isn’t  as  precise  and  complete  as  the  native  a&i   experience,  why  bother?    in  addition  to  broadening  the  subject  scope  by  including  many  of  the   more  narrow  and  deep  subject  metadata,  there  is  also  the  importance  of  serendipitous  finding.     that  content,  in  the  context  of  a  quick  user  search,  may  drive  the  user  to  just  the  right  thing  that   they  need.    in  addition,  my  belief  is  that  with  that  content,  we  can  build  search  systems  that  are   deeper  than  google  scholar,  and  by  extension  provide  our  end  users  with  a  superior  search   experience.    and  so  i  advocate  for  innovating  now  instead  of  waiting  to  work  out  all  of  the  details.     i  am  not  suggesting  moving  forward  callously,  but  swiftly.    the  work  that  niso  has  done  on  the   open  data  initiative  has  resulted  in  some  good  recommendations  about  how  to  proceed.    for   example,  they  have  suggested  two  usage  metrics  that  could  be  valuable  for  measuring  a&i  content   use  in  discovery  systems:  search  counts  (by  collection  and  customer  for  a&i  databases)  and   results  clicks  (number  of  times  an  end  user  clicks  on  a  content  provider’s  content  in  a  set  of   results).3     while  i  think  these  types  of  metrics  are  aligned  with  the  types  of  measures  that  libraries  evaluate   a&i  database  usage  by,  i  think  at  the  same  time  they  don’t  really  say  much  about  the  overall  value   of  the  resources  themselves.    sometimes  in  the  library  profession,  our  obsession  for  counting  stuff   loses  connection  with  collecting  metrics  that  actually  say  something  about  impact.    of  the  two   counts,  i  could  see  perhaps  counting  the  result  clicks  as  having  more  value.    in  this  instance,   knowing  that  a  user  found  something  of  interest  from  a  specific  resource  at  the  very  least  indicates   that  it  led  the  user  some  place.    i  think  the  measure  of  search  counts  by  collection  is  less  useful.    at   best  it  indicates  that  the  resource  was  searched,  but  it  tells  us  nothing  about  who  was  searching   for  an  item,  what  they  found,  or  what  they  subsequently  did  with  the  item  once  they  found  it.    i  do   think  we  in  libraries  need  to  consider  the  bigger  picture.    regardless  of  the  number  of  searches   information  technology  and  libraries  |  march  2015     3   (which  doesn’t  really  tell  us  anything  anyway),  we  need  to  recognize  the  value  alone  of  including   the  a&i  content,  and  instead  of  trying  to  determine  the  value  of  the  resource  by  the  number  of   times  it  was  searched,  focus  more  on  the  breadth  of  exposure  that  content  is  getting  by  inclusion   in  the  discovery  system.   i  think  a  more  useful  technical  requirement  for  discovery  providers  would  be  to  provide  pathways   to  specific  a&i  resources  within  the  context  of  a  user’s  search—not  dissimilar  to  how  google   places  sponsored  content  at  the  top  of  their  search  results,  a  kind  of  promotional  widget.    in  this   case,  using  metadata  returned  from  the  query,  the  systems  could  calculate  which  one  or  two   specific  resources  would  guide  the  user  to  more  in  depth  research.    by  virtue  of  inclusion  of  the   resource  in  the  discovery  system,  those  resources  could  become  part  of  the  promotional  widget.     this  would  guide  users  back  to  the  native  a&i  resource  which  both  libraries  and  a&i  providers   want,  and  it  would  do  that  in  a  more  intuitive  and  meaningful  way  for  the  end  user.   all  of  the  parties  involved  in  the  discovery  discussion  can  bring  something  to  the  table  if  we  want   to  solve  these  issues  in  a  timely  way.    i  hope  that  a&i  publishers  and  discovery  system  providers   make  haste  and  get  agreements  underway  for  content  sharing  and  i  would  recommend  that   instead  of  focusing  on  requiring  finished  implementations  based  in  complex  requirement  before   loading  content,  both  of  them  should  instead  focus  on  some  achievable  short  and  long  term  goals.     integrating  a&i  content  perfectly  will  take  some  time  to  complete  and  the  longer  we  wait,  the   longer  our  users  have  a  sub-­‐optimal  discovery  experience.    discovery  providers  need  to  make  long   term  commitments  to  developing  mechanisms  that  satisfy  usage  metrics  for  a&i  content,  although   i  would  recommend  defining  measures  that  have  true  value.    a&i  providers  should  be  measured  in   their  demands:  while  their  stakes  in  system  integration  is  real,  there  runs  a  risk  of  content   providers  vying  for  their  content  to  be  preferred  when  relevancy  neutrality  is  paramount  for  a   discovery  system  to  be  effective.    i  think  it  is  worth  lauding  the  efforts  of  a  few  trailblazing  a&i   publishers  such  as  thomson  reuters  and  proquest  who  have  made  agreements  with  some  of  the   discovery  providers  and  are  sharing  their  a&i  content  already,  providing  some  precedent  for   sharing  a&i  content.    lastly,  libraries  and  knowledge  workers  need  to  develop  better  means  for   calculating  overall  resource  value,  moving  beyond  strict  counts  to  thinking  of  ways  to  determine   the  overall  scholarly/pedagogical  impact  of  those  resources  and  they  need  to  make  the  fact  alone   that  an  a&i  publisher  shares  its  data  with  a  discovery  provider  indicate  significant  value  for  the   resource.                       editorial  board  thoughts:  a&i  databases  |  dehmlow     4     references     1.    nfais,  recommended  practices:  discovery  systems.  nfais,

 the  practice  of  libraries  and  librarianship  is  changing  is  an  understatement.  throughout   their  history,  libraries  have  adapted  and  evolved  to  better  meet  the  needs  of  the  communities   served.  from  content  collected  and/or  archived,  to  facilities  and  services  provided,  a   constant  throughout  has  been  the  adoption,  incorporation,  and  eventual  transition  away   from  technologies  along  the  way:  clay  tablets  and  papyrus  scrolls  giving  way  to  the  codex;  the   printing  press  and  eventual  mass  production  and  collection  of  books  yielding  to  information   communication  technology  such  as  computer  workstations  and  the  internet.  indeed,  the   rapid  and  widespread  adoption  of  the  internet  has  enabled  entire  topologies  of  information   to  change  –  morphing  from  ponderous  print  tomes  into  digital  databases,  effectively  escaping   the  walls  of  libraries  and  archives  altogether.1   in  reflection  of  end-­‐users’  growing  preference  for  easily  accessible  digital  materials,  libraries   have  responded  with  the  creation  of  new  spaces  and  services.  repositioning  physical,  digital,   human,  and  social  resources  to  better  meet  the  needs  of  the  communities  supported,  the   information  commons2  that  is  the  library  begins  to  acquire  a  more  technological  edge.  the   concept  of  a  library  service  or  area  referred  to  specifically  as  an  information  commons  can  be   traced  to  as  early  as  1992  with  the  opening  of  the  information  arcade  at  the  university  of   iowa  –  specifically  designed  to  provide  end-­‐users  technology  tools,  with  a  stated  mission  “to   facilitate  the  integration  of  new  technology  into  teaching,  learning,  and  research,  by   promoting  the  discovery  of  new  ways  to  access,  gather,  organize,  analyze,  manage,  create,   record,  and  transmit  information.”3   first  mentioned  in  the  literature  in  1994,  discussion  of  the  idea  itself  waited  another  five   years,  with  donald  beagle  writing  about  the  theoretical  underpinnings  of  “the  new  service   delivery  model”  in  1999.  defined  as  “a  cluster  of  network  access  points  and  associated  it   tools  situated  in  the  context  of  physical,  digital,  human,  and  social  resources  organized  in   support  of  learning.”  a  flurry  of  articles  followed,  with  the  idea  seeming  to  have  caught  the   collective  imagination  of  libraries  generally  by  2004.  information  commons  as  named  spaces   within  libraries  made  “…  sudden,  dramatic,  and  widespread  appearance  in  academic  and   research  libraries  across  the  country  and  around  the  world.”4  scott  bennett  went  further,  in   2008  asking  flatly:  “who  would  today  build  or  renovate  an  academic  library  without   including  an  information  commons?”5   this  proliferation  and  transition  has  not  been  limited  to  academic  libraries;  for  decades,   libraries  of  all  type,  shape,  and  size,  have  been  similarly

 end-­‐user  access  and  learning.  by  2006,  a  new  variation  of  the   information  commons  had  entered  the  vernacular:  the  learning  commons.  defined  by  beagle   as  the  result  of  information  commons  resources  “organized  in  collaboration  with  learning   initiatives  sponsored  by  other  academic  units,  or  aligned  with  learning  outcomes  defined   through  a  cooperative  process.”6  a  subset  of  the  broader  concept,  when  the  library   collaborates  with  stakeholders  external  to  the  library  to  collaboratively  achieve  academic   learning  outcomes,  it  becomes  operationally  a  learning  commons.  one  can  easily  conceive  of   the  learning  commons  more  broadly  by  considering  learning  outcomes  desirable  within  the   context  of  particular  library  types:  school  libraries  with  offerings  and  programs  in  alignment   with  broader  k-­‐12  curricula;  public  libraries  in  support  of  lifelong  learning  and  participatory   citizenship;  special  libraries  in  alignment  with  other  niche-­‐specific  learning  outcomes.   note  that  not  all  information  commons  are  learning  commons.  as  defined,  the  learning   commons  depends  on  the  actions  and  involvement  of  other  units  that  establish  the  mission,   and  associated  learning  goals,  of  the  institution.  others  must  join  with  the  library’s  effort  in   order  to  create  and  nourish  such  spaces  in  a  way  that  is  deeply  responsive  to  the  aspirations   of  the  institution:  “the  fundamental  difference  between  the  information  and  the  learning   commons  is  that  the  former  supports  the  institutional  mission  while  the  latter  enacts  it.”   (bennett  2008,  emphasis  added)  at  a  time  when  libraries  are  undergoing  such  rapid  and   significant  transformation,  it’s  hard  to  dismiss  such  collaborative  effort  as  merely  trendy  –   such  spaces,  and  the  library  by  extension,  become  of  even  more  fundamental  relevance  to  the   broader  organization.   in  short,  resources  are  provisioned  in  the  information  commons  so  that  learning  can  happen;   collaborative  effort  with  stakeholders  beyond  the  library,  but  within  the  organization,   ensures  that  learning  does  happen.   drawing  a  parallel,  what  if  the  library  were  to  go  beyond  simply  repositioning  resources  in   support  of  learning  –  indeed,  beyond  working  with  other  units  of  the  organization  to   collaboratively  align  and  provision  resources  in  support  of  achieving  organizational  learning   outcomes?  to  go  beyond  strategic  alignment  with  the  aspirations  of  the  institution,  involving   stakeholders  from  beyond  the  immediate  organization  in  the  creation  and  support  of  such   spaces?  provisioning  library  spaces  and  services  that  are  deeply  responsive  to  the   aspirations  of  the  greater  community?  arguably  this  is  where  the  relatively  recent   introduction  of  makerspaces  into  the  library  fits  in.  the  annual  environmental  scan   performed  by  the  new  media  consortium  (nmc)  has  for  a  number  of  years  identified   makerspaces  to  be  on  its  short-­‐term  adoption  horizon  –  the  2015  library  edition  goes   further,  identifying  a  core  value:     the  introduction  of  makerspaces  in  the  academic  library  is  inspiring  a  mode  of  learning  that   has  immediate  applications  in  the  real  world.  aspiring  inventors  and  entrepreneurs  are     information  technology  and  libraries  |  september  2015         4   taking  advantage  of  these  spaces  to  access  tools  that  help  them  make  their  dreams  into   concrete  products  that  have  marketable  value.7     aspects  of  the  information  commons  are  present  in  library  makerspace  –  not  only  in  the   access  to  traditional  library  resources,  but  also  in  the  shift  toward  providing  support  of  21st-­‐ century  literacies  in  the  creation,  design,  and  engineering  of  output.  with  the  acquisition  and   use  of  these  literacies  in  collaboration  with  and  in  support  of  the  goals  of  the  greater   institution,  it  is  also  a  learning  commons;  for  example,  in  the  case  of  a  school  or  public  library   where  makerspace  activities  and  engagement  collaboratively  meet  and  support  learning   outcomes  including  increased  engagement  with  science,  technology,  engineering,  the  arts,   and  math  (steam)  disciplines.  consider  the  further  example  of  university  students   leveraging  makerspace  technology  as  part  of  ste(a)m  outreach  efforts  to  local  middle   schools  in  the  hope  of  kindling  interest,  or  partnering  with  the  local  discovery  museum  in  the   production  of  a  mini  maker-­‐faire  to  carry  that  interest  forward.  alternatively,  a  team  of   students  conceiving,  then  prototyping  and  patenting  a  new  technology  with  the  active  and   direct  support  of  the  library  commons,  going  on  to  eventually  launch  as  a  business.  to  the   extent  the  library  can  springboard  off  the  combination  of  makerspace  with  information  or   learning  commons  to  engage  stakeholders  from  beyond  the  institution,  it  can  go  beyond  –   becoming  something  broader,  and  potentially  transformative;  even  as  it  enables  progress   toward  collaboratively  achieving  community  goals,  outcomes,  and  aspirations.   the  hallmark  of  community  engagement  with  such  library  facilities  is  a  spontaneous   innovation  that  seems  to  flow  naturally.  library?  information  or  learning  commons?   arguably  such  spaces  are  more  accurately  named  innovation  commons.   beyond  solidifying  the  library’s  place  as  a  hub  of  access,  creation,  and  engagement  across   disciplinary  and  organizational  boundaries,  the  direct  support  of  innovation  –  the  process  of   going  from  idea  to  an  actual  good  or  service  with  a  real  perceived  value    –  is  in  potential   alignment  with  the  aspirations  of  the  broader  community.  in  collaboration  with  stakeholders   from  across  the  community,  from  economic  development  and  government  representatives  to   businesses  and  private  individuals,  broader  outcomes  and  aspirations  of  the  greater   community  can  be  identified  and  supported.    nevertheless,  simply  adding  makerspace   technology  to  an  information  or  learning  commons  does  not  automatically  create  an   innovation  commons.  it  is  in  the  broader  conversation,  along  with  the  catalyzation,   identification  of  and  support  for  the  greater  aspirations  of  the  community,  that  the  commons   begins  to  assume  its  proper  role  in  the  greater  ecosystem.  leveraging  the  deliberate   application  of  information,  with  imagination,  and  initiative,  enabling  end-­‐users  to  go  from   idea  all  the  way  to  useful  product  or  service  is  something  that  community  stakeholders  see  as   a  tangible  value.           editorial  board  thoughts:  rise  of  the  innovation  commons  |  colegrove     doi:

(jessica.hall@fresnolibrary.org) community librarian, fresno county public library. © 2020. “where would you like to go?” is the question of the day. we have stood atop the great wall of china, swam with sea lions in the galapagos islands, and walked along the vast red sands of mars. each journey was unique and available through the library. as a community librarian in charge of outreach to seniors and veterans, i first learned about the virtual tour idea from a colleague who returned from a conference excited to tell me about a workshop she had attended. the workshop she had taken described a program which utilized google expeditions to take seniors on virtual tours. this idea stayed with me for months until fresno county public library obtained the $3000 value of libraries grant, which was funded by the california library services act. as a part of this grant, $2905 went to purchase a google expeditions kit and supplied to create a virtual reality program called journey with veterans. the kit includes 5 viewers and 1 tablet. a viewer is basically a google cardboard except the case is plastic and there is a smartphone inside of the case. during the program, i use the table to select and run each tour. the tour i select on the tablet is projected to the 5 viewers so participants can experience it. in this manner, veterans can explore places without physically having to travel anywhere. the journey with veterans program took the technology to the veterans instead of requiring them to come into the library. the two locations that were chosen were the veterans home of california fresno and the community living center at the va medical center in fresno, ca. from the time the program began in september 2019 to march 2020, when the pandemic shutdown brought a halt to the program, the library hosted 26 sessions at these two locations with 182 veterans. in sessions where more than 5 people were in attendance, the viewers were shared between the participants. the tablet and smartphones inside of the viewers have an app installed on them called google expeditions which is the software that runs the tours. one hotspot, which was already owned by the library, was used for this program. it is a requirement that all the viewers and the tablet are connected to the same wifi. having a portable wifi connection was necessary to run this program in locations where there was not access to a strong internet connection. each tour is a selection of still 360-degree views. the landscape does not move. instead, the participant turns their head around, up and down to look at the entire scene. the control tablet included additional menu items not seen by participants. these items included scripts that i can read off about the landscape we are looking at and suggested points of interest that i could highlight for participants. when i selected the point of interest on the tablet, the participant would see arrows pointing to that area of their screen. the participant would follow the arrows by turning their head in the direction that was indicated. the participants knew they were looking at the area of interest when the arrows disappeared and was replaced by a white circle surrounding the relevant portion of the screen. mailto:jessica.hall@fresnolibrary.org information technology and libraries december 2020 journey with veterans | hall 2 the viewers did not have straps attached to them and there was no way to attach straps to them. therefore, the viewer could not be strapped to the participant’s head. instead, the participant had to hold up the viewer the entire time they wished to look through it. this presented a challenge for participants who did not have the ability to hold the viewer on their own. at the locations i went to, there were staff available to help and they would hold the viewer up to a participant’s eyes. in some cases, one staff person held the viewer up for the participant while another would turn the participant’s wheelchair in a circle so they could see the entire image. each program lasted 30-45 minutes but the amount of time looking through the viewer was kept to around 15-20 minutes. the rest of the time was filled with talking about the location that we are viewing. for the veterans in memory care at the veterans home of california fresno, this program was designed with the hope that it would allow the veterans to reminisce about places they had visited and lived in and encouraged them to talk about their experiences. some of the participants had been to the countries that we visited virtually and they reminisced on their time there. at every session, the participants shared their enthusiasm and eagerness to continue the program. the program once was tried with music. on one of my first visits to the community living center at the va medical center, a participant asked if he could play music in the background. since i had thought about incorporating music into the program, i agreed, and the participant played some classical music from his own device. though it was a good idea, the execution did not work well. the music was coming from one location, which made it too loud when one stood near it but too quiet once one walked too far away. i found the music difficult to talk over while giving the tour. i believe that incorporating sounds of the location we visit, such as the sounds of the countryside or a big city would make the experience more immersive. however, i have yet to find a way to do so successfully. after the grant ended, i continued the program at both locations. the partnership i had created at the veterans home of california-fresno grew into a second program, storytime with veterans which was requested by specifically by the residents. i alternated my visits so that some weeks we did a virtual reality program and some weeks i read to them. one time, there was miscommunication and the activity coordinator thought i had come to read a story but i was under the impression that it was a virtual reality week and so i had brought the google expeditions with me. the solution was to do both. one of the google expeditions tours is a very short and much abridged virtual reality version of twenty thousand leagues under the sea by jules verne. the tour used artwork to represent scenes from the books and each scene tells a different part of the story. the veterans home’s residents were treated to both a story and a virtual reality tour at the same time. up until the library’s shutdown in mid-march due to covid-19, i was in the process of expanding the use of the google expeditions but was unable to continue. since then, the equipment has not been used. restarting the program now includes multiple challenges, not the least of which is sanitizing the devices. sanitation was a consideration even before covid-19 and sanitary virtual reality masks were acquired using grant funds as part of the initial program. these masks look like strips of cloth that line the eyes with strings to hook it around the ears to hold it in place. cleaning products were also purchased and utilized to clean the devices after each program. information technology and libraries december 2020 journey with veterans | hall 3 before covid-19, a viewer could be handled by multiple people before it was cleaned. i always handled them first to prepare them for use. then i handed each one to the participant. occasionally they were also handled by staff. i always cleaned the viewers right after the program ended but not during the program. with the current covid-19 restrictions, the sanitation practices previously used are inadequate. i do not know the future of the program in a postcovid-19 world, but i intend to begin the program again once when it becomes safe to do so and i will incorporate all required precautions and restrictions. i look forward to once more being able to take veterans on exciting virtual journeys. lib-s-mocs-kmc364-20141005043703 68 book reviews indiana seminar on information networks (isin). proceedings. compiled by donald p. hammer and gary c. lelvis. west lafayette, indiana: purdue university libraries, 1972. 91 p. (available at no charge from the extension division, indiana state library, 140 north senate avenue, indianapolis, indiana 46204 as long as the supply lasts). the indiana seminar on information networks (october 26-28, 1971) was an attempt to introduce indiana librarians to the benefits (and presumably problems) of library networking. papers included in the proceedings are introduction to networks (maryann duggan), library of congress marc & recon (lucia j. rather), nelinet (ronald f. miller), an on-line interlibrary circulation and bibliographic searching demonstration (gary c. lelvis and donald p. hammer), ohio college library center (frederick g. kilgour), user response to the facts (facsimile tran.smission system) netu1ork (lynn r. hard), indiana twx network discussion (margaret d. egan & abbie d. h eitger), and how does the n etwork serve the researcher? (irwin h. pizer) . as with any collection of written papers or oral presentations, the quality is mixed. the papers are introductory in nature, the pizer article being the exception. the majority report "case studies" of particular automated operations and/ or networks (marc & recon, nelinet, oclc, facts) . the facts article is the most interesting of these "case studies" because it moves beyond simply reporting "how we done it good" into an evaluation of why the network did not succeed (the network did not meet a real and/or consciously recognized need of the libraries it was proposing to serve) and emphasizes the importance of careful planning. any wouldbe network planner should read this article; there are many lessons to be learned. although the collected papers have all of the disadvantages usually associated with a collection of oral presentations (material is loosely organized and lacks continuity, introductory and oversimplified, repetitive, and out of date), they are a valuable addition to the growing body of literature dealing with networks both from the idealized conceptual view and, perhaps more importantly, from the practical reality view of existing networks. kenneth j. bierman systems librarian virginia polytechnic institute computers and systems; an introduction for librarians, by john eyre and peter tonks. hamden, connecticut, linnet books (shoe string press), 1971. 127 p. $5. 75. isbn: 0-208-01073-4. at last an inexpensive introductory text specifically written for librarians and library students! not since n. s. m. cox's the computer and the library have we had such a short, easy to read, yet comprehensive, description of the essentials. complementing the text are twenty-nine figures illustrating everything from batch and real-time processors, disc drives, program process, and systems flowcharts to data elements, formats, and input procedures, marc ii records on magnetic tapes, and sample pages from a computer-produced author catalog. the text reads like a well-organized glossary, treats the subjects of library use of computers and systems analysis in a way at once simple and informative. the authors had tested the material with students in courses at the school of librarianship of the polytechnic of north london. thanks to the british-american cooperation surrounding marc efforts, this book will be as useful in our library school classes as it is in theirs. the index d eserves a special note because it was compiled after the style of precis developed by the british national bibliography. it is a facet analysis of the text featuring access to "activity:thing: type:aspect" in a prescribed permuted order. although there is not much emphasis in such a text on subject access or information retrieval, this is not entirely overlooked and this index serves as an excellent example of what could be done by computer. truly an excellent introduction to computers and systems analysis for librarians! a two-page bibliography contains suggestions for further reading on the topic or for an expanded reading of various applications of computers in libraries. pauline atherton school of library science syracuse university isis: integrated scientific information system; a general description of an ap· proach to computerised bibliographical control, by william schieber. geneva: international labour office, 1971. 115p. $1.50. this document is a well-written description of the computerized library system developed at the international labour office. planning and development for the system began in 1963. it has been implemented and is now in operation within the central library and documentation bmnch of the ilo. the isis bibliographic control system is a large file system for storing, processing, and retrieving bibliographic information. the ilo data base consists of some 45,000 records of books, periodical articles, and other documents. each record consists of conventional bibliographic data (with less detailed definitions than marc data, however) plus an abstract. in form, the abstract appears to be written in natural language, but all descriptor words used in the abstract are taken from a controlled vocabulary and, in fact, provide subject indexing. on-line terminals are used for ide searches. the search system allows searches by subject descriptors, language, and date of publication. sequential formulation of the search allows control of the number of responses to a desirable size. records are also indexed on various data fields, such book reviews 69 as author and title. display of records and browsing are handled on line, but printing of lists or bibliographies is handled through subsequent batch printing jobs. regularly scheduled outputs of the system include printed catalogs, indexes, and authority lists. two other systems have been developed at the ilo using some programs and files of the bibliographic control system. one is for controlling loans of library books, the other is for serials data and includes a subsystem for routing library periodicals. these three major systems are described in some detail in this report. a fourth section deals with system monitoring and control. costs are discussed here. the isis system is an interesting and unique one even though the system is geared primarily to a special library environment. it is evident that much careful thought and attention to detail went into the system design and development. the integrated use of programs and files as described here and the details of some design elements make this a useful document. the report itself is well done. describing a complex system for a varied audience is a difficult task. the author, william d. schieber, has put together an excellent example of a systems report document. charles t. payne systems development office university of chicago library title derivative indexing techniques: a comparative study, by hilda feinberg. metuchen, n.j.: the scarecrow press, 1973. x+297p.; index and bibliography. this book is primarily a survey of key word indexes, with some discussion of issues in indexing. the survey is quite good, but already out of date. the discussion is unfortunate. the survey covers a wide range of computer-based article title key word indexes, including extreme cases such as permuterm. sample pages are included for fifty-six indexes, and thirteen lists of excluded words ("stopwords") are· given. reproduction of samples is generally ex70 journal of library automation vol. 6/ 1 march 1973 cellent, and this portion is valuable in showing the virtues and defects of various approaches to key word indexing. since this survey, at least three major libraries have begun publication of key word indexes to serial titles, a type of index with different problems which is likely to be more common in the future. the discussion suffers from a lack of focus. there are no clear standards for key word indexes or the traditional tools they complement or replace, and studies of user preference and convenience have been limited and inconclusive. it is difficult to say what makes a key word index more or less workable, and this book seems to cloud the issues even more. ms. feinberg makes some questionable and unsupported assumptions about what users think, want, and need, and a number of recommendations which are at best only applicable to indexes of article titles in scientific fields. take three major recommendations: plural and singular forms should be interfiled, synonyms and similar words should be interfiled, and foreign titles should be translated. the university of california (berkeley) library found "college," "university," "company" and "papers" to be good exclusion words, while "colleges," "universities," "companies," and "paper" are good subject words. synonym control increases homonym problems, makes for longer (and thus more difficult to use) lists, and entails difficult decisions as to what con~titute true synonyms. translation raises the qm ..., tion of whether a user should be guided to a publication he may not be able to read. in sum, these and similar decisions should depend much more on the field of study and user population than on this type of general treatment. there are other problems reflecting deficiencies in the areas of technical background, understanding of typography, and appreciation of some reasons for key word indexing. ms. feinberg comes out strongly in favor of "title enrichment"-adding artificial titles to improve indexing. this, however, adds cost and time to the key word approach, and subtracts from its clear advantages. a large section is devoted to an experimental study of different indexing programs, with the result that different programs produce different in dexes. generally, the discussion detracts from the survey. finally, the title chosen seems unfortunate. "key word indexing" may not be an ideal term, but it is fairly well known; must we introduce yet another vague, polysyllabi<, phrase, "title derivative indexing"? walt crawford university of california berkeley accountability: systems planning in education. leon lessinger & associates. creta d. sabine, editor. homewood, ill.: etc publications, 1973. 242 pages. "accountability" has become a rallying cry in many educational circles of late: for the public in its demand for visible results for educational dollars, and for educators as they attempt to define and defend new programs. this well-sequenced collection of nine papers on this subject addresses the problem of accountability at all levels of the educational 'enterprise. first is a conceptualization of systemsplanning through an explanation of the systems approach, cost effectiveness, and cost analysis. next are specific methods of systems-planning at the classroom, community college, university, and state <kpartment of education levels. a specific case study shows in some detail how to analyze the costs and effectiveness of one individualized course offering. finally, a series of appendixes provides a method of classifying expenditures, a highly detailed classification of school curricula, a method of cost-analyzing school data collection, and a useful current glossary. as a whole, the volume is a practical combination of both theory and application, with many flow charts that will be adaptable to local needs at several levels of education. all ten authors are now practicing educational administrators, and their previous classroom experience is revealed by the frequent everyday illustrations in many chapters. the brief summary sections at the end of each paper, while often too short to recapitulate the essence of the chapter, can give the reader a helpful overview before reading the chapter proper. other than the more-frequentthan-usual typographic errors, the only obvious weakness of the collection is the somewhat inconsistent use of the important ppbs concept (program-planning-budget system); the concept is a recurrent theme m the book, and the editor would have been better advised to first derivl' a single definition from which all authors would then develop their respective discussions. the up-to-date list of references at the end of each chapter will be useful to the book reviews 71 student of accountability who must delve more deeply. for librarians, a major relevance of this volume will be the varied approaches to cost-effectiveness analysis of instruction in relation to learning materials, since in this task, librarian and instructor must work hand in hand. for the librarian and educator who are uninitiated in systems analysis, this volume is well recommended for basic instruction in the rationale and basic elements of systems approaches to accountability. david s. martin mill valley school district califomia a hybrid access method for bibliographic records abraham bookstein: the university of chicago graduate library school, chicago, illinois. 97 this paper defines an access method for bibliographic reco1'ds that combines features of the sea1'ch key app1'oach and the inverted file approach. it is a refinement of the search key technique that permits its extension to la1'ge files. a method by which this approach can be efficiently implemented is suggested. introduction a major problem in the development of computerized files of bibliographic records is the creation of a convenient and economical mechanism to access the records. as the problem of organizing a file for efficient access is a general one, a number of structural devices have been suggested. hsiao and harary propose an abstract model for file structure that encompasses those that are discussed most frequently. 1 lefkovitz discusses these techniques in more detail and considers the advantages of each for implementation, while dodd and knuth describe the data structures needed in implementing such files. 2-4 these works reveal the interrelation between a file's organization and its retrieval capability, but the determination of which routes of access to provide must be the task of those responsible for creating the file. such a determination may involve consideration of both the intrinsic structure of the items represented by the file and the conditions under which the file is to be used. they will influence which file organization should be chosen. because of the complexity inherent in collections of bibliographic " items, the problem of determining suitable access routes to library files has been a challenging one. almost any datum may, on some occasion, be a useful means of entering the file. dimsdale and heaps, in their discussion of a file structure for an on-line catalog, explicitly propose words from the title, authors, and library of congress call numbers. 5 in this paper we shall consider the problem of accessing a known item by means of information contained in the author and title field. we shall concentrate on two approaches that have received much attention-the use 98 i ottrnal of library automation vol. 7/2 june 197 4 of a truncated search key, referred to simply as search key, and the use of boolean expressions of key words from the title. both of these are intended to allow a user simple entry into the file when the full field of information is long, complicated, or, perhaps, incompletely known by the user. the authors and titles of books often share these characteristics. each of the approaches, taken by itself, has its strengths and its weaknesses. we will discuss each technique in tum, and then suggest an elaboration of the search key technique that incorporates some features of the boolean search technique; this combination of techniques should enable systems that are committed to the use of search keys as a primary access route to extend this technique to large files. it introduces into the search key approach some of the flexibility of the key word approach. search keys this approach defines at least one special field, the search key, for each item represented in the file, and allows retrieval of the record for an item by inputting the value of its search key. 68 the search key should be constructed so as to allow its evaluation from data that are available at the time of access. the main advantage of this approach as it is usually implemented has been its great simplicity-for a broad variety of materials, the key can be readily evaluated and quickly entered into the system. the most heavily discussed defect of this approach is that it will sometimes retrieve a considerable number of records to a single request. consider, for example, these works: 1. ramsay, blanche margaret. relation of various climactic factors to the growth and development of sugar beets, and 2. ramsey, ian thomas. religious language. the popular ( 3, 3) search key, constructed by concatenating the first three letters of the author's name and the first three letters of the first significant word of the title, would represent each of these by the key ram, rel. this defect becomes particularly severe with certain corporate entries and works such as conference proceedings. furthermore, this difficulty can be expected to become aggravated as the file increases in size or, equivalently, as some items are given multiple search key values; the latter may be required in order to alleviate the problems inherent in having to access items with ambiguous or multiple forms of titles. attempts to remedy the difficulty of multiple retrievals have resulted in increasingly complex keys, defeating the purpose for which this technique was originally proposed. a more complex key makes greater demands on the user, encourages mistakes on entry, and also might increase the likelihood of two individuals deriving different keys for the same item. inverted files in this approach, a user attempts to retrieve a record by forming a hyb1·id access methodjbookstein 99 boolean expression of key words taken from various fields of the desired record. 9• 10 stanford university's ballots, for example, allows the user to enter the file by means of words taken from the title of a book. two advantages of this approach as compared to the search key are that: (a) the user need not know the information required to form a search key, for example the first word of the title; and (b) the user is able to enter the system by what appears to him to be the most distinctive terms in the title, thereby minimizing false drops. users of ballots have found that because of the speed at which computers operate, usually the indexes can be manipulated and a record retrieved immediately, or in a very short period of time. fayollat gives an estimate of two to five seconds as the response time. the most direct way to implement this approach would be to access each record in the file and compare it to the request. for any but the smallest files this would be unreasonably costly in computer time. an alternative, and customary, implementation involves maintenance of indexes of key words. while experience with this approach, as at the ballots project, recommends this as a workable implementation, it can be costly in terms of the computer costs involved with upkeeping the indexes. hybrid approach we offer for consideration an elaboration of the search key approach that incorporates aspects of the key word approach. it is intended as an alternative to developing increasingly complex keys for systems adopting a search key approach, but for which a simple search key retrieves too many items; possibly this approach can be selectively applied to the more troublesome parts of the file, such as to items with corporate authors. this approach associates a search key with each record, hopefully one that is simple and easily derived. a user would begin by entering into the system the search key. if the system finds that the number of items that would be retrieved exceeds a preset threshold, it would output a message requesting that the user enter a set of key words taken from various fields in the records; the title would be very useful in this regard. the system first generates a subfile of records having the desired search key. if a hashing technique is used, constructing this subfile can be accomplished quickly and at relatively little cost in space for tables. 11 once the smaller file is formed, a complete search of the full records can be made for the key words. since the system operates in two phases, it is less sensitive to the number of records the search key retrieves as far as user considerations are concerned. ease of use becomes the dominating objective in designing the search key. experience to date suggests that even a very simple search key will almost always produce less than thirty records with files having in the order of 100,000 records. however, a complete search of a reduced file of thirty records should be feasible; in fact, usually the subfile will be no larger than two or three records. from one point of view, in the hybrid system, we can 100 journal of library automation vol. 7/2 june 1974 think of the search key not as an access mechanism, as earlier, but rather as a file reduction mechanism. this system trades the cost of maintaining and storing large indexes for an increase in costs of computer processing; only relatively easily maintained hash tables for fixed length search keys need be maintained. an accurate assessment of these costs can be made only after the statistical characteristics of various search keys have been explored. observations if it should be desired to implement a hybrid system, the following observations would be in order: 1. among the current concerns of facilities with large bibliographic files is file compaction. if records will have to be searched for key words, this consideration will influence planning of compaction techniques. for example, a technique such as cop ack, which completely scrambles the bits in a record, would not be permissible. 12 use of variable length codes for characters, such as in hoffman coding, would allow searches for key words; most likely such a search would be implemented by attempting to match substrings of bits rather than matching on the full word level.13 another common compaction technique, bigram coding, would also complicate the separation of words unless the blank were prevented from combining with other characters; because of the frequency with which the blank occurs with other characters, this restriction would interfere considerably with the efficacy of the technique.u a different approach would be to recognize that each word could have only two "spellings," depending on what happened to the blank preceding the word, and both spellings could be tested. (a brief survey of the above compaction techniques has been conducted by fouty.15 ) 2. though a complete search for key words would be feasible on a small file, it is possible to expedite the search considerably by means of a technique devised by malcolm harrison, which involves adding a fixed number of bits, or signatures, to each field on which a search can take place; these additional bits are derived in a well-defined way from the original field. 16• 17 this subfield is a fixed-size representation of the full field in a form that can be used to very rapidly eliminate most records which would not pass the key word matching test. it is stored in the index to the file along with the address of the record. though this preliminary test is not foolproof, it could considerably reduce the size of the subfile that requires a more costly complete search, thereby reducing the number of disc accesses. if this procedure is adopted, a possible sequence of events would be as follows: (a) a user inputs a search key and, perhaps, a couple of key words. these may be words he is certain are in the title, although the hybrid access methodjbookstein 101 name of a series, the author, or subject headings would also represent candidates. (b) on the basis of the search key the system creates a sub file of record addresses and signatures taken from the index-if the user is unfortunate the subfile would have a large number of records. (c) a rapid preliminary search of the signatures using the harrison technique is made of the reduced file to test whether the key words could possibly be part of a record. this pass eliminates a number of records; how efficient this technique is will depend on the number of bits the system associates with each representative field. (d) finally, the full records of the remaining items are retrieved and a full search is made. at any point, if the subfile is too large, the system may request additional key words. example of technique implementation how to create a signature for a record is best explained by means of an example. many variants are possible, and we have chosen a simple one for the purposes of illustration. the signature we shall create will consist of one word of thirty-two bits. we proceed as follows: 1. list all the substantive words of the title, e.g., relation, various, climactic, ... , beets, if we consider one of the titles mentioned above. 2. truncate each word to, say, the first four characters: rela, vari, ... , beet. other truncation sizes, or no truncation at all, may be elected. 3. for each string of characters produced in this way, form the two consecutive strings of three characters. for example, "vari" contributes "var" and "ari." since the first word is already represented in the search key, we may use only the second three-letter string for that word-here "rela" is represented only by "ela." implicit in this implementation is the assumption that if a user remembers anything about a word, he will correctly remember at least its first three characters, and that the first four characters go a long way toward giving the word away. 4. finally, we turn on a bit in the signature for each three-character string, essentially creating a hash code of thirty-two bits. the code should incorporate information from all three characters. for purposes of illustration, the following method will suffice: (a) for each letter in a three-letter string, substitute the rank of that letter in the alphabet, beginning with 01 for a-thus "ela" becomes 05,12,01; (b) consider the string of digits as a single six-digit number, and multiply that number by 1111-thus "ela" becomes 51201 and then 56884311; (c) divide by 32 and use the remainder as the address of the bit which is to be turned on. the string "ela" is thus associated with bit number 23, where the leftmost bit is the oth bit. as the algorithm is 102 journal of library automation vol. 7/2 june 1974 applied to each three-character string, the signature is formed. the book by blanche margaret ramsay is accordingly represented by: 01000011100100011000010100100101 similarly the book by ian thomas ramsey is represented by: 00000000000000010000000001000010 suppose a patron, or a cataloger, wishes to see the record associated with mr. ramsey's book on religious language. he would enter the search key, ram,rel, and, say, the word "language." among the index entries reb·ieved by the search key will be the desired book, and also the book by ramsay, dealing with sugar beets. the signature for the word "language" has bits numbered 30 and 25 turned on. since the ramsay book does not have both of these turned on (in this case neither bit is turned on), it is immediately eliminated; the actual records retrieved from the file will be only those for which both bits are on. though it is quite possible that false drops can be incurred in this way, clearly many incorrect records are easily eliminated. note also that the user need input only as much of the word as he has confidence in, provided that at least three characters are produced. use of the above technique leaves a number of decisions that still must be made by the system designer. among these are: 1. should a signature be associated with each item, or only a part of them, for example, with corporate authors? 2. how much truncation is appropriate, if any? if no truncation is used, then the user can input fragments of words, including fragments taken from the middle of a word, as well as full words. on the other hand, as the signature fills up, the probability of a false drop increases. earlier research contains a formula that allows us to estimate this effect.18 consider a title with six significant words. fayollat has found that in a file of biomedical serials, about 83 percent of all items will be of this size or less.19 similarly, let us assume that the average word in the title is made up of eight characters, a modal number of characters in fayollat's data base. if the user requests a term composed also of eight characters, then table 1 estimates the probability of a false drop as a function of the b·uncation size. table l. probability of false drops as function of truncation size. truncation probability of length false drop 3 .17 4 .10 5 .08 6 .08 7 .08 8 .09 it is seen that for this typical case, the method eliminates about 90 perhybrid access methodjbookstein 103 cent of the false drops. it must be understood that longer titles, or titles made up of longer words, will be more likely to be erroneously retrieved; on the other hand, the user can increase his precision by inputting a larger number of terms. the above calculation assumes that terms in the request and in the title are independent; of course, all items having the same search key as the request and sharing the discriminant word will be retrieved; presumably the user will minimize this effect by choosing distinctive words. fayollat finds that 50 percent of the words appearing in his titles occur only once. conclusion in conclusion, we propose a technique for entering a bibliographic data base that retains the simplicity of search keys while also including some of the flexibility that boolean expressions of key words have for uniquely defining an item. in such a system, the only indexes that must be maintained are the hash tables; the other indexes, such as title words, are replaced by the search algorithms. if a signature, the supplementary field described above, is also stored in the index, this approach reduces the number of disc accesses. a major limitation of this approach is that a user must be able to provide a search key; this is shared, however, with systems depending exclusively on search keys. furthermore, since the system is capable of handling larger numbers of retums on the search key, there is greater inducement to associating more search key values for each item. thus such a hybrid system allows groups that find search keys an attractive access technique to extend this approach to file sizes which strain the capacities of the direct approach. references 1. d. hsiao

lori mestre information technology and libraries | september 2014 45 abstract this article presents a case study exploring the use of a student coding camp as a bottom-up mobile design process to generate library mobile apps. a code camp sources student programmer talent and ideas for designing software services and features. this case study reviews process, outcomes, and next steps in mobile web app coding camps. it concludes by offering implications for services design beyond the local camp presented in this study. by understanding how patrons expect to integrate library services and resources into their use of mobile devices, librarians can better design the user experience for this environment. introduction mobile applications offer an exciting opportunity for libraries to expand the reach of their services, to build new connections, and to offer unique, previously unavailable services for their users. mobile apps not only provide the ability to present library services through mobile views (e.g., the library catalog and library website), but they can tap into an ever-increasing list of mobile-specific features. by understanding how patrons expect to integrate library services and resources into their use of mobile devices, librarians can better design the user experience for this environment. by adjusting the normal app production workflow to directly involve students during the formative stages of mobile app conception and design, libraries have the potential to generate products that more accurately anticipate real-life student needs. this article details one such approach, which sources student talent to code apps in a fast-paced, collaborative setting. as part of a two-year institute of museum and library services (imls) grant, an academic library– based research team investigated three different methods for involving users in the app development process—a student competition, integrated computer science class projects, and the coding camp described in this article. the coding camp method focuses on a trend in mobile software development of having intensive two-to-three-day coding events that result in working prototypes of applications (e.g., iphonedevcamp, http://www.iphonedevcamp.org/). coders typically work in groups to simultaneously learn how new software works, and also develop a functioning app that matches an area of personal interest. camps promote collaboration, which provides additional networking and social outcomes to attendees. additionally, camps provide an david ward (dh-ward@illinois.edu) is reference services librarian, james hahn (imhahn@illinois.edu) is orientation services & environments librarian, and lori mestre (lmestre@illinois.edu) is head, undergraduate library and professor of library administration, university of illinois at urbana-champaign. http://www.iphonedevcamp.org/ mailto:dh-ward@illinois.edu mailto:imhahn@illinois.edu mailto:lmestre@illinois.edu adventure code camp: library mobile design in the backcountry | ward, hahn, and mestre 46 opportunity for software makers to promote their services and products, and they can result in new code and ideas on which to base future products. for academic libraries, a camp environment provides an educational opportunity for students, particularly those in a field with a computing or engineering focus, to learn new coding languages and techniques and to gain experience with a professional software production process that runs the full timeline from conception to finished product. coding camps offer a chance for librarians to get direct student feedback on their own software development goals. the resulting applications provide potential benefits to both groups—students have a functional prototype to enhance their classroom experiences and a codebase to build on for future projects, and the librarians gain an insight into students’ desires for the content of mobile apps, code to integrate into existing apps, and direct student input into the iterative design process. this article presents the results of a mobile application coding camp held in fall 2013. the camp method was tested as a way to explore a less timeand staff-intensive process for involving students in the creation of library mobile apps. three specific research questions framed this investigation: 1. what library and course-related needs do students believe would benefit from the development of a mobile application? 2. is the library providing access to data that is relevant to these needs, and is it available in a format (e.g., restful apis) that end users can easily adopt into their own application design process? 3. how viable is the coding camp method for generating usable mobile app prototypes? literature review in line with efforts in academic libraries to operationalize participatory design for novel service implementation,1 the library approach to code camps included sourcing student technical expertise in line with other tech companies’ approaches to quickly iterating prototypes that may advance or enhance company services. while coding camps happen in corporate settings, other types of camps try to publicize technologies, like a programming language, while others still are directed toward a specific cohort.2 the departure point for the library was in understanding other ways the library might consider organizing and pairing its resources of apis with other available campus services. a few highly visible and notable corporate “hackfests” or “hackdays” include the facebook hackdays, in which facebook timeline was developed (http://www.businessinsider.com/facebook-timeline-began-as-a-hackathon-project-2012-1). the mobile app company twitter also has monthly hackfests where employees from across the company work for a sustained period (a weekend or friday) on new ideas putting together prototypes that may transition into new services for the company. http://www.businessinsider.com/facebook-timeline-began-as-a-hackathon-project-2012-1 information technology and libraries | september 2014 47 an example of code camps from academia are the mhacks camps at the university of michigan (http://mhacks.challengepost.com/), among the largest code camps for university students in the midwest. these camps are notable for their funding from corporations and for their support of student travel from colleges around the country to participate at the university of michigan. at each event, coders are encouraged to make use of the corporate apis that student programmers may make use of once they graduate or form companies after graduation. on the professional front, digital library code meet-ups (such as that of the code4lib preconference: http://code4lib.org/) are an opportunity for library technologists to share strategies and new directions in software using hands-on group coding sessions that last a half or full day. a recent digital event for the digital public library of america (dpla) hosted hackfests to demonstrate interface and functional possibilities with the source content in the dpla. similarly, the hathi trust research center organized a developer track for api coaching at their conference so that participants would have hands-on opportunities to use the hathi trust api (http://www.hathitrust.org/htrc_uncamp2013). goals of coding camps include development of new services or creation of value-added services on already existing operations. code is not required to be complete, but functional prototypes help showcase new ways of approaching problems or novel solutions. recently, mhacks issued the call to form new businesses at their winter hackathon (http://www.mhacks.org). libraries are typically less interested in new businesses, but rather seek new service ideas and new principles for organizing content via mobile and to do so in such a way that will source student preferences for location specific services, a key focus for the research team’s student/library collaborative imls grant. method while the camp itself took only two days, there was a significant amount of lead-time needed to prepare. in addition to obtaining standard campus institutional-review-board permissions for the study, it was also necessary to consult the office of technology management to devise an assignment agreement covering the software generated by the camp. the research team chose a model that gave participating students the option to assign co-ownership of the code they developed to the library. this meant that both students and the library could independently develop applications using the code generated during the camp. marketing for the camp specifically targeted departments and courses where students with interest and skills for mobile application development were likely to be found, particularly in computer science and engineering. individual instructors were contacted, as well as registered student organizations, to help promote the camp. attendees were directed to an online application form, where they were asked to provide information on their coding skills and details on their interest in mobile application development. http://mhacks.challengepost.com/ http://code4lib.org/ http://www.hathitrust.org/htrc_uncamp2013 http://www.mhacks.org/ adventure code camp: library mobile design in the backcountry | ward, hahn, and mestre 48 ten students were ultimately selected from the pool and, of those, six attended the camp. a precamp package was sent to these students to help them prepare for the short, intense timeframe the event entailed. this package included details on library data that were available to base applications on through web apis, as well as brief tutorials on the coding languages and data formats participants needed to be familiar with (e.g., javascript, json, xml, etc.). participants were also provided with information on parking and other logistics for the event. the research team consisted of librarians and academic professionals involved in public services and mobile design, and student coders employed by the library to serve as peer mentors. the team designed the camp as a two-day experience occurring over a weekend (friday evening to saturday late afternoon). the first day was scheduled as an introduction to the camp, with details on library and related apis that could be used for apps and an opportunity for participants to brainstorm app ideas and form design teams. the day ended with some preliminary coding and consultation with camp organizers about planned directions and needs for the second day. the second day of the camp mostly for coding, with breaks scheduled for food, presentations of work-in-progress, and an opportunity to ask questions of the research team. the day ended with each team presenting their app, describing their motivation in designing it and the functionality they had been able to code into it. given the brief turnaround time, the research team put a heavy focus during the orientation session on clearly articulating the need to develop apps germane to student library needs. examples from the student mobile app design competition conducted in february 2013 were provided as starting points for discussion, as these reflected known student desires for mobile library applications.3 after the camp ended, students who elected to share their code with the library were given details on how and where to deposit the code. post-camp debriefing interviews (lasting 30 to forty-five minutes each) were scheduled individually with all participants to get their feedback on the setup of the event as well as what they felt they learned from the experience. discussion researcher observations and feedback from students, both during the camp and in individual interviews afterwards, led to several insights about what sorts of outcomes libraries might anticipate from running camps, how to best structure library coding camps, what outcomes students anticipate from participating in a sponsored camp environment, and what features and preferences students have for mobile apps designed to support their academic endeavors. a key student assumption, which emerged from comments at the event and through subsequent student interviews, was that students anticipated completing a fully functioning mobile app by the end of camp. instead, the two student teams each finished with an app that, while it included some of the features they desired, still required additional coding to be fully realized. several information technology and libraries | september 2014 49 suggestions were made for how this need might be met at future events. the most consistent feedback from the students was that they would have liked an additional day of coding (three total camp days), so that they could have gotten further on the implementation of their app ideas. during the exit interviews, one student noted that the two-day timeframe really only allowed for sketching out an idea for an app, not coding it from scratch. a pair of related suggestions from students included having templates for mobile apps available to review to get up to speed on new frameworks (particularly jquery), and secondly, a longer meetand-greet for teams prior to beginning work during which they could compare available coding skills and have some extended brainstorming of app ideas. students were somewhat mixed in their desire for assistance in developing app ideas—some appreciated the open-endedness of the camp, but others wanted a more organizer-driven approach. some students suggested having time to work with library staff after the camp to finish or polish their apps. this observation suggests the enthusiasm students had for the camp itself, and specifically for having a social, structured, and mentored opportunity to develop their coding skills. based on these requests, the research team created “office hours” on the fly after the camp ended to support this request. research team members and coding staff communicated times when team members could come into the library and get additional help with developing their apps. the students had very similar themes for app features to those that the research team observed in an earlier student mobile app competition study. notable categories included the following: • identify and build connections with peers from courses. • discover campus resources and spaces. • facilitate common activities such as studying and meeting for group work. students remarked that the camp was an opportunity to both meet people with similar coding interests as well as to learn more about specific functional areas of app development (specific coding languages, user interface design, etc.) in which they had little experience. jquery and javascript for user-facing designs were particular areas of interest. many students had some indepth background working on pieces of a finished software product but had not previously done start-to-finish software design; this was a big selling point for the camp. the collaborative nature of the camp also matched students’ preferences to work in teams and to learn from peers. while the research team had coders on hand to assist with both the library apis, as well as jquery basics, most teams did the majority of their work themselves, and preferred self-discovery. each team did eventually ask for coding advice, but this occurred toward the end of the camp, once their apps were largely coded and they needed assistance overcoming particular sticking points. the other piece of advice students asked organizers about concerned identifying apis for locations of campus maps, and other related resources to serve as data sources powering their apps. in the course of assisting with these requests, researchers discovered another key issue facing library mobile app development—the lack of campus standards for presenting information across adventure code camp: library mobile design in the backcountry | ward, hahn, and mestre 50 different colleges and departments. in particular, maps of rooms inside campus buildings were not provided in a consistent or comprehensive way. this was particularly frustrating to the team that was attempting to develop an app featuring turn-by-turn navigation and directions to meeting rooms and computer labs. in addition to sharing information on known apis and data sources, camp organizers also learned about previously unknown data sources from the student teams. one example was a json feed for the current availability of computers in labs provided by the college of engineering. while this feed was beneficial to starting work on an app for one team, it also led to frustration because feeds for other campus computer labs did not exist, and the team was limited to designing around the specific labs that did have this information available. observed student discussions about the randomness of data availability also highlighted one of the key themes of student-centered design—the conceptualization of a university as a single entity, the various parts of which combine and come in and out of focus depending on the current student task. related student feedback from one of the post-event interviews described a strong desire to create integrated, multifunction apps to meet student needs as opposed to a variety of apps that each did one thing. the siloed nature of campus infrastructures frustrates this desire to some extent but also creates opportunities for students to build a tool that meets a real need among their peers to comprehend and organize their academic environment. this observation also matches those found during the aforementioned student competition. conclusion and future directions student feedback on the camp, as a whole, was very positive, and in the individual interviews, students noted they would like to participate in another camp if it was offered. on the library side, the research team felt that the camp was useful to their ongoing mobile app development process, partially for the code generated but primarily for the direct feedback on what types of apps students wanted to see. the start-up time and costs for the project were low, as expected, and the insights into student mobile preferences seemed proportionate to this outlay. the camp method should be reproducible in a variety of library environments. the key assets other libraries will need to have in place to run a camp include staff with knowledge of client-side api use (in particular jquery, cors, or related skills), and knowledge of campus data sources that students may wish to pull from. third-party apis with bibliographic data (e.g., good reads) could also be used as placeholders for libraries that do not have access to apis for their own catalogs or discovery systems. student suggestions for extending the camp by a day, and their ideas for how to structure it for student success, were very specific and actionable and provided excellent guidance. one of their ideas was to develop tutorials and templates that could be introduced as a pre-camp meeting. this would not add too much prep time. another idea for a future camp would be to develop a specific theme for teams, which would allow for more documentation of and practice with specific apis. information technology and libraries | september 2014 51 the low attendance was a concern, so for the next camp twice the number of desired participants will be invited to ensure both a variety of coding skills and interests as well as opportunities for more teams to be formed. additionally, partnerships with student coding groups or related classes should help to drive up attendance. the biggest difficulty moving forward will be developing campus standards for data that can be made available to students about resources, spaces, and services. as noted above, students typically do not design a “library app,” rather they look to build a “student app” that pulls in a variety of data from across campus. functions of apps are therefore more oriented toward common student activities like studying, socializing, and learning. a related challenge will be to provide adequate format and delivery mechanisms for access to supporting data feeds. cognizant of the silo issue, noted above, as libraries present their own data for student consumption, these tendencies towards a unified view need to be taken into account. completion of an assignment is more than identifying three scholarly sources; it might involve identifying a space to do the research, locating peers or mentors for either the research or writing process, locating suitable technology to complete an assignment, and a variety of other needs. the features and information presented on a library’s website should be designed as modular building blocks that can fit into other campus services in a similar way to how course reserves are sometimes presented in campus learning management services alongside syllabi and assignments. separating library content (e.g., full-text articles, room information, research services) from library process can help with freeing information about what libraries have to offer and can facilitate broader discovery of services and resources at point of need. key to this process is recognizing the student desire to shape the resources they need into a comprehensible format that matches their workflow rather than forcing students to learn a specific, isolated, and inflexible path for each part of the projects they work on. this study has shown that a collaborative process in technology design can yield insights into students’ conceptual models about how spaces, resources, and services can be implemented. while the traditional model of service development often leaves these considerations until the very end in a summative assessment of service, the coding camp and collaborative methods presented here provide librarians a new tool for adding depth to service design and implementation, ultimately resulting in services and platforms that are informed by a more wellrounded and deeper understanding of the student mobile-use experience. in that regard, the initial research questions that framed this study could also be used by other libraries as they explore the library and course-related needs that students could benefit from with the development of mobile applications, as well as to determine if their library provides access to data that is relevant to those needs. the results from this study have affirmed that, for at least the library from this study, that the coding camp method is viable for generating usable mobile app prototypes. it also affirmed that by directly involving students during the formative stages of mobile app conception and design, the products of those apps more accurately reflect real-life student needs. adventure code camp: library mobile design in the

a public services librarian, worcester public library. abstract the worcester public library (wpl) offers several digital learning courses to our adult patrons, and among them is “intro to coding using python”. this 6-session class teaches basic programming concepts and the vocabulary of software development. it prepares students to take more intensive, college-level classes. the bureau of labor statistics predicts a bright future for software developers, web developers, and software engineers. wpl is committed to helping patrons increase their “hireability” and we believe our python class will help patrons break into these lucrative and gratifying professions… or just have fun. history and details of our class i came to librarianship from a long career in software development, so when i joined the worcester public library in january 2018 as a public services librarian, my manager proposed that i teach a class in programming. she asked me to research what language would be best. python got high marks for ease of use, flexibility, growing popularity, and a very active online community. once i selected a language, i had to choose an environment to teach it in – or so i thought. i had absolutely no experience in front of a classroom, and few pedagogical skills, so i sought out an online python course within which to teach. i decided to use the code academy (ca) website as our programming environment. ca has selfguided classes in a number of subjects and the free beginning python course seemed to be just what we needed. i went through the whole class myself before using it as courseware. my intent was to help students register for ca, then, each day, teach them the concepts in that day’s ca lesson. they would then be set to do the online lesson and assignments. we first offered python in june 2018. problems with ca came up right from the start: students registered for the wrong class (despite the handout explicitly naming the correct class) and ca frequently tried to upsell to a not-free python class. since ca’s classes are moocs (massive open online courses), the developers built in an automated way of correcting student code: embedded behind each web page of the course, there’s code that examines the student’s code and decides whether it is acceptable or not. good in theory, not so good in practice. ca’s “code-behind” is flawed and sometimes prevented students from advancing to the next lesson. mailto:mfriedenthal@mywpl.org information technology and libraries june 2020 intro to coding using python at the worcester public library | friedenthal 2 moreover, some of the ca tasks were inane. for example, one lesson incorporated a kind of mad libs game. this is where the instructions ask, for example, for 13 nouns and 11 adjectives, and these are combined with set sentences to generate a silly story. this assignment turned out to be too long and difficult to fulfill, preventing students from advancing. although i used ca the first few times i offered the class, i subsequently abandoned it and wrote my own classroom material. after determining that ca wasn’t appropriate, i chose an online ide where the students could code independently. this platform worked well when i tested it ahead of time, but when the whole class tried to log on at once, we received denial-of-service error messages. hurriedly moving on to plan c, i chose thonny, a free python ide which we downloaded to each pc in the lab (see https://thonny.org/). each student receives a free manual (see figure 1), which i wrote. every time i’ve offered this class i’ve edited the manual, clarifying those topics the students had a hard time with. i’ve also added new material, including commands students have shown me. it is now 90 pages long, written in microsoft word, and printed in color. we use soft binders with metal fasteners. figure 1. intro to coding using python manual developed for the course. https://thonny.org/ information technology and libraries june 2020 intro to coding using python at the worcester public library | friedenthal 3 the manual consists of the following sections: • cover: course name, dates we meet, time class starts and ends, location, instructor’s name, manual version number, and a place for the student to write their own name. • syllabus: goals for each of the six sessions. this is aspirational. • basic information about programming, including an online alternative to thonny, for students who don’t have a computer at home and wish to use our public computers for homework. • lessons 1 – 17: “hello world” and beyond. • lesson 18: object oriented design, which i consider to be advanced, optional material. skipped if time is pressing or the class isn’t ready for it. • lesson 19: wrap-up: o how to write good code. o how to debug. o list of suggested topics for further study. o online resources for python forums and community. • list of wpl‘s print resources on python and programming. • relevant comic strips and cartoons. in march 2019, my manager asked me to start assigning homework. if a student attends all six sessions and makes a decent attempt at each assignment, at the sixth session they receive a certificate of completion. the certificate has the wpl name & logo, the student’s name, and my signature. typically three or four students earn a certificate. homework is emailed to me as an attachment. this class meets on tuesday evenings and i tell students to send me their homework as soon as possible. inevitably, several students don’t email me until the following monday. while i don’t give out grades, i do spend considerable time reviewing homework, line by line, and i email back detailed feedback. when the january 2020 course started, i found that between october’s class and january, outlook implemented a security protocol which removes certain file extensions from incoming email. and – you can see where this is going – the .py python extension was one of them. i told students to rename their python code files from xxxx.py to xxxx.py.doc, where “xxxx” is their program name. this fools outlook into thinking the file is a microsoft word document and the email is delivered to me intact. when it arrives, i remove the .doc extension from the attachment and save it to a student-specific file. then i open the file in thonny and review it. physically, our computer lab contains an instructor’s computer and twelve student computers (see figure 2). it also has a projector which projects the active window from the instructor’s computer onto a screen: usually the class manual. i use dry erase markers in a variety of colors to illustrate the concepts on a whiteboard. there is also a supply of pencils on hand for student notetaking use. the class is offered once per season. although the classroom can accommodate twelve students, we set our maximum registration to fourteen, which allows us to maximize attendance even if patrons cancel or don’t show up. and if all fourteen do attend the first class, we have two lap tops i information technology and libraries june 2020 intro to coding using python at the worcester public library | friedenthal 4 can bring into the lab. we also maintain a small waitlist, usually of five spots. we’ve offered this class seven times and the registration and waitlists have been full every time. sometimes we have to turn students away. figure 2. classroom at worcester public library. however, we had a problem with registered patrons not showing up, so last spring we implemented a process where, about a week before class starts, i email each student, asking them confirm their continued interest in the class. i tell them that if they are no longer interested—or don’t respond i will give the seat we reserved for them to another interested patron (from the waitlist). in this email i also outline how the course is structured and that they can each earn a certificate of completion. i tell them class starts promptly at 5:30 and to please plan accordingly. some students don’t check their email. some patrons show up without ever registering; they are told registration is required and to try again in a few months. i keep track of attendance on an excel spreadsheet. here in worcester, ma, weather is definitely a factor for our winter sessions. information technology and libraries june 2020 intro to coding using python at the worcester public library | friedenthal 5 over time i’ve made the class more dynamic. i have a student read a paragraph in the manual aloud. i’ve switched around the order of some lessons, in response to student questions. i have them play a game to teach boolean logic: “if you live in worcester and you love pizza, stand up!”… then: “if you live in worcester or you love pizza, stand up!” students range from experienced programmers (of other languages), to people with no experience but great aptitude, to people who just never seem to “get it”. this material is technical and i try hard to communicate the concepts but i lose a few students every time. we ask our patrons for feedback on all of our programs. our python students have written: • “… the classes were formatted in an organized manner that was beginner friendly” • “the manual is a big help. i'm thankful that the program is free.” • “… coding is fun and i learned a new skill.” • “this made me think critically and helped me understand where my errors in the programs were.” wpl is proud to offer classes that make a difference in our patrons’ lives. abstract history and details of our class applying topic modeling for automated creation of descriptive metadata for digital collections article applying topic modeling for automated creation of descriptive metadata for digital collections monika glowacka-musial information technology and libraries | june 2022 https://doi.org/10.6017/ital.v41i2.13799 monika glowacka-musial (monikagm@nmsu.edu) is assistant professor/metadata librarian, new mexico state university library. © 2022. abstract creation of descriptive metadata for digital objects tends to be a laborious process. specifically, subject analysis that seeks to classify the intellectual content of digitized documents typically requires considerable time and effort to determine subject headings that best represent the substance of these documents. this project examines the use of topic modeling to streamline the workflow for assigning subject headings to the digital collection of new mexico state university news releases issued between 1958 and 2020. the optimization of the workflow enables timely scholarly access to unique primary source documentation. introduction digital scholarship relies on digital collections and data. in the influential book digital_humanities, anna burdick and her associates affirm that humanistic knowledge production depends on collection building and curation.1 access to historical documents and data resources is essential for the development of new research questions and methodologies.2 this project utilizes topic modeling to support building a digital collection of institutional news releases. it is one of the initiatives to apply digital technologies in the library workflows. new mexico state university news releases in response to a growing scholarly and public interest in original university press announcements, the digitization of past nmsu print news releases was approved in september 2013. sixty years of news releases starting from the late 1950s to the present were to be included. one of the arguments presented in justification of the project was that these institutional news briefs have a truly unique historical value. researchers view university press announcements as anchors in the history of nmsu and the region, particularly for dating events and initiatives. they also find official communications essential for studying the way the news was framed by participants and the university administration. historically, the relationships between the university and the local media had always been a major concern of college administrators: how to respect the freedom of the press, while ensuring responsible and factual journalism, and how to build an effective partnership that would benefit both sides?3 to address these questions, the administration early on established the college’s information services that have issued news releases about campus events, programs, and developments in the college’s research, teaching, and service. these formal news repor ts representing the perspective of the university have been regularly distributed to local and worldwide media for many decades. this collection has become one of the most popular primary sources documenting a history of the southwestern educational institution. mailto:monikagm@nmsu.edu information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 2 since the beginning of the digitization project, thousands of press releases had been scanned, described, and added to the digital collection. currently, the collection features press releases issued by the university between 1958 and 1974. there is still a lot to be done. the most timeconsuming element in the process is adding metadata, including library of congress subject headings, to individual news releases. with decreasing personnel, dwindling library resources, and competing work priorities, the progress on the project has slowed substantially. its revitalization requires a fresh, problem-solving approach that would allow for a significant reduction of time that catalogers spend on metadata creation. in search for a viable solution, topic modeling, a computational tool for classifying large collections of texts, was put to the test and generated promising results. the following sections describe the tools, data, and process created for this experiment in some detail. topic modeling and its applications topic modeling (tm) is one of the methodologies used in natural language processing (nlp). it was specifically designed for text mining and discovering hidden patterns in huge collections of documents, images, and networks.4 according to practitioners, topic modeling is best viewed as a statistical tool for text exploration and open-ended discovery.5 it has been used extensively in computer science, genetics, marketing, political science, journalism, and digital humanities f or the last two decades. a growing literature on topic modeling applications provides clear evidence of its viability.6 examples of tm applications in digital social sciences and humanities include finding geographic themes from gps-associated documents on social media platforms such as flickr and twitter,7 selecting news articles on opposition to euro currency from financial times data,8 identifying paragraphs on epistemological concerns in english and german novels ,9 tracking research trends in different disciplines,10 and revealing dominant themes in newspapers,11 governance literature,12 and wikipedia entries.13 topic modeling was applied in addition to text mining to enhance access to large digital collections by providing minimal description and enriching metadata, including subject headings .14 also, a possibility of using topic modeling to determine the subject headings for books on project gutenberg was explored.15 topic modeling in a nutshell topic models help to identify the contents of document collections. topic modeling is a process of discovering clusters of words that best represent a set of topics. figure 1 shows the basic idea behind topic modeling. a large collection of text documents (the scrolls on top) consists of thousands of words (shown symbolically at the bottom). the algorithm seeks for the most frequent words that tend to occur in proximity and clusters them together. each cluster, referred to as a topic, has a set of words with their probabilities of belonging to a given topic. each document in the collection displays a set of combined topics to different degrees. here, documents are seen as mixtures of topics, and topics are seen as mixtures of words.16 topics also provide context to words. documents that have similar combinations of topics tend to be related. as a result, a large collection of text documents can be represented by a limited set of topics (as presented by icons in the middle of the figure). information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 3 figure 1. basic idea behind topic modeling. topics and subject headings combined the original purpose of topic modeling, as formulated by david blei and his associates in 2003, was to make large collections of texts more approachable for scholars by organizing texts automatically based on latent topics.17 these hidden topics can be discovered, measured, and consequently used by scholars to navigate the collection. the purpose of assigning subject headings is to identify “aboutness,” or simply subject concepts, covered by the intellectual content of a given work, and then again collocate related works. 18 since both topic models and subject headings have a similar purpose, although very different methodology and scale, we decided to combine them and make topic models a prerequisite for assigning subject headings. in such a scenario, the computer deals with the scale of text collections that are beyond human reading capacity and catalogers then fine-tune the results generated by the algorithm. the following methods section shows subsequent stages involved in the process of semiautomated assignment of subject headings to documents. methods overview for topic modeling, we used the algorithm of latent dirichlet allocation (lda).19 lda takes a document-term matrix, with rows corresponding to documents, and columns corresponding to terms (words) and, based on semirandom exploration, finds optimal probabilities of topics in documents (called gammas), and probabilities of terms in topics (called betas). after lda generates a set of topics that best represent the collection of news releases, each topic is associated with several subject headings that were previously assigned to news releases by catalogers. for a new news release, lda finds a set of most representative topics. subject headings information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 4 associated with the dominant topics are combined into a list of subject candidates presented to a cataloger. the last step involves a cataloger using a short list of subject candidates for selecting subject headings for news releases. training data training data used in this project consists of over 6,000 news releases (from 1958 to 1967) annotated with metadata. only two metadata properties—titles and subject headings—were considered. created by catalogers, both properties reflect the content of news releases accurately, although mistakes may sometimes happen. the values from the titles field were converted into a document-term matrix that, in turn, became an input for the algorithm. texts produced by ocr on original news releases were not included in the analysis due to their poor quality. detailed steps of the proposed method: 1. topic modeling on training data: a. run standard preprocessing of training text data, including tokenization, stop words removal, and stemming. b. run topic modeling (lda) where each document from the training data set is assigned a set of topics (subsets of words), each one with a measurable contribution to the document. 2. assignment of subject headings to topics.20 for each topic: a. select a number of documents with the highest probability (gamma) for the topic. we used 400. b. gather a set of subject headings assigned to documents produced in 2.a. and arrange them with decreasing frequency (freq) of occurrence in the set. 3. assignment of subject headings to a new document. a. assign to the new document gammas (probabilities) of topics using the lda model trained in 1.b. b. in subsequent topics, for each subject heading calculate its weight in the document as a product of its frequency in the topic (freq) and probability of the topic (gamma) in the document; for subject headings duplicated across topics, sum up their weights across topics. c. create a list of candidate subject headings processed in 3.b. in descending order with respect to their weights in the document. implementation there is a growing number of tools used for topic modeling.21 for this project, we used the r programming language, which has many packages for data preprocessing and topic modeling (tm).22 below are listed r packages used for this project: • topicmodels with functions: lda() producing topic models, posterior() for assigning topics to test documents by pretrained models and perplexity() for perplexity calculation 23 • tidytext with tidying functions that allow for re-arrangements and exploring data as well as for interpreting the models • textstem for preprocessing data, including stemming and lemmatization information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 5 • tidyr, dplyr, and stringr for data and strings manipulation and arrangements • ggplot2 for data visualizations the code related to topic modeling was mostly reused from the datacamp class on topic modeling.24 occasionally, data.table data structure was applied instead of data.frame. in addition to standard stop-words, custom stop-words including initials, names of weekdays, and dates were removed from the corpus using function anti_join(). for finding topics in test documents by a pretrained model, function posterior() from the r package topicmodels was used.25 the extra step needed before using function posterior() was to align the new document with the document-term matrix used for training the lda model.26 results for assessing the method’s performance, we adopted the idea of recall. in this specific context, recall is defined as the fraction of original subject headings (i.e., those assigned to a document manually by a cataloger) that are present on the list of candidate subject headings produced by the method. the average recall is estimated using a leave-one-out setting.27 once a single test document is set aside, the lda model is trained on the remaining documents and recall is calculated for the tested document using the list of candidate subject headings produced by the method. then, recall is averaged over a set of testing documents. this approach produces an estimate of the method’s performance if tested on a new document. information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 6 figure 2. average recall as a function of size of list with subject headings candidates. figure 2 shows the dependence of average recall on length of list of candidate subjects produced by the method. recall is averaged over 1,500 randomly selected test documents. the dashed line represents the chance level performance, i.e., when the method would produce a random subset of all subject headings available in the data. on a list of 100 suggested subject headings, the recall is on average above 0.6 and for a list of 500 candidate subject headings, above 0.8. even though the average recall stays noticeably below 1 (recall value 1 would mean perfect performance), at the same time it is still considerably above the chance level. the results presented in figure 2 were produced by the lda model trained with 16 topics. one of the parameters affecting the method performance is the number of topics used by the lda model. for finding the number of topics corresponding to the highest recall, an overall measure of recall across different lengths of the subject candidate list was defined as the cumulative recall for first 100 subject candidates. we assumed that 100 is a likely size of candidate lists that catalogers would be willing to go through. figure 3 shows the cumulative recall for different numbers of topics, based on which 16 were chosen as the optimum. interestingly, this corresponds wel l with the perplexity dependence on number of topics (fig. 4). the perplexity, a measure of model’s surprise at the data, shows how the model fits the data—a smaller number means a better fit, i.e., a better topic model.28 information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 7 figure 3. cumulative recall as a function of number of topics in the lda model. information technology and libraries june 2022 applying topic modeling for automated creation of descriptive metadata | glowacka-musial 8 figure 4. perplexity of the lda model as a function of number of topics in the lda model. to give a better idea about the method performance, figure 5 shows the distribution of recall for individual test documents, for a list of 100 subject headings. since most documents in the training data have just a few subject headings, there is only a small set of discrete values possible for recall for individual documents. the distribution is wide, with a fraction of documents with no subject heading present on the proposed list (recall = 0) but also with a bigger fraction of documents fully covered by the list (recall = 1). information technology and libraries june 2022

following examples show the sets of subject headings selected by the algorithm that include subject headings (in bold blue) chosen originally by catalogers. example 1 title of news release: “‘romeo

consult before assigning subject headings to news releases. it is important to note that this method produces subject headings that are already present in the training data. the list of available subject headings can be expanded by periodic updates of the training data to include all entries in the catalog, assuming catalogers will add, where needed, subjects not present so far in the data set. in this project we utilized metadata from just two fields: titles and subject head ings. although documents’ titles are supposed to compactly represent the content of documents, we expect that the presented approach would give better results if the full text (ocr) was analyzed. in this project, the limiting factors were both quality of print copies and robustness of available ocr tools. in some cases, subject annotations are imperfect, depending on skills and experience of catalogers. that also affects the performance of our method that relies on quality of subject assignments. on the other hand, there are cases when the method suggests subjects that are fitting the content of news releases but were not selected by catalogers. this indicates that the method can also be used to refine the existing annotations. conclusion we propose a way to streamline the workflow of metadata creation for university news releases by applying topic modeling. first, we use this digital technology to identify topics in a large collection of text documents. then, we associate the discovered topics with sets of subject headings. finally, to a new document, we assign those subject headings that are associated with the document’s most dominant topics. the proposed method facilitates the process of document annotation. it produces short lists of candidate subject headings that account for a significant part of original labeling performed by catalogers. this approach can be applied to support annotation of any large digital collection of text documents. one of the advantages of applying topic modeling is that it produces numeric representations of text documents. these numeric representations can be used by advanced analytical methodologies, including machine learning, for numerous practical purposes in library workflows like text categorization, collocation of similar materials, enhancing metadata for digital collections, finding trends in government literature, etc. in addition, mastering digital methodologies by librarians may open new ways of collaboration among them and digital scholars across university campuses. as johnson and dehmlow argue, “... digital humanities represent a clear opportunity for libraries to offer significant value to the academy, not only in the areas of tool and consultations, but also in collaborative expertise that supports workflows for librarians and scholars alike.”29 digital technologies are best learned in hands-on practice. if librarians are to contribute to the development of digital scholarship, then

libraries | december 2020 https://doi.org/10.6017/ital.v39i4.12123 isabel vargas ochoa (ivargas2@csustan.edu) is web services librarian, california state university, stanislaus. © 2020. abstract the university library at california state university, stanislaus is not only undergoing a library building renovation, but a website redesign as well. the library conducted a user-centered usability study to collect data in order to best lead the library website “renovation.” a prototype was created to assess an audience-based navigation design, homepage content framework, and heading terminology. the usability study consisted of 38 student participants. it was determined that a topicbased navigation design will be implemented instead of an audience-based navigation, a search-all search box will be integrated, and the headings and menu links will be modified to avoid ambiguous library terminology. further research on different navigation and content designs, and usability design approaches, will be explored for future studies. introduction the university library at california state university, stanislaus is currently undergoing a much anticipated and necessary redesign of the library website. website redesigns are crucial and a part of website maintenance to acclimate with modern technology and meet accessibility standards. “if librarians are expected to be excellent communicators at the reference desk and in the classroom, then the library website should complement the work of a librarian.”1 in this case, a library website prototype was created, using a springshare llc product, libguides cms, as the testing subject for our user-centered usability study. the usability study was completed with 38 student participants belonging to different academic years and areas of study. the library website prototype tested was designed using a user-based design framework and an audience-based navigation. this study found issues reported from users based on navigation design and ambiguous library terminology. an audience-based navigation was chosen in order to best organize and group the information and services offered to best make them accessible for users. however, an audience-based navigation will directly affect users and their search behaviors.2 the prototype, like the current library website, did not have a search-all search box during the study. a catalog search box was utilized to test whether or not the catalog was enough for student participants to find information. this also forced the participants to utilize the menu navigation. literature review the design and approach of usability studies, preference for types of search boxes, navigation design, and library terminology evolve over time in parallel with technology changes. most recent usability studies use screen and audio recording tools as opposed to written observation notes. participants in recent studies are also more adapted to learning how to navigate websites, as mailto:ivargas2@csustan.edu information technology and libraries december 2020 navigation design and library terminology | ochoa 2 opposed to participants in usability studies twenty years ago. regardless, it’s crucial to compare the results from previous usability studies to analyze differences and similarities. different types of usability studies include user-centered usability studies and heuristic usability studies. this study chose a user-centered approach because of the library's desire to collect data and feedback from student users. the way in which the usability study is presented is also detrimental to the approach. website usability studies are meant to test the website, although participants may unconsciously believe they are being tested. in tidal’s library website case study (2012) researchers assured the participants that “the web site was being tested and not the participants themselves.”3 this unconscious belief may also affect the data collected from the participants and “influence user behavior, including number of times students might attempt to find a resource or complete a given task.”4 the features tested were the navigation design and homepage elements. the navigation design in the prototype was developed to test an audience-based navigation design (see figure 1). an audience-based navigation design organizes the navigation content by audience type. 5 that is to say, the user will begin their search by identifying themselves first. although this design can organize content in a more efficient manner, especially for organizations that have specific, known audiences, critics argue that this design forces users to identify themselves before searching for information, thus taking them out of their task mindset.6 for this usability study, i wanted to test this navigation design and compare the results to our current navigation design which is a topicbased navigation design. a topic-based navigation design is developed to present topics as navigation content.7 this design is our current library website navigation design (see figure 2) figure 1. screenshot of the audience-based navigation design developed for the library website prototype. figure 2. screenshot of the current content-based navigation design in the library website. information technology and libraries december 2020 navigation design and library terminology | ochoa 3 designing the navigation and homepage also means choosing accessible terms that are relevant to all users. unfortunately, over the course of many decades, library terminology has been a hindrance for student users. terms such as “catalog,” “reference,” and “research guides” are still difficult for users to understand. as conrad states (2019), “students are not predisposed to think of a ‘research guide’ as a useful tool to help them get started.”8 a research guide isn’t necessarily a self-explanatory term. in many ways, the phrase is ambiguous. augustine’s case study in 2002 had similar difficulties. students “lack of understanding and awareness of library resources impacted their ability more than the organization of the site did.”9 it’s unsettling to know that our own terminology has been deterring users from accessing library resources for decades. librarians use library terminology to such an extent that it’s part of our everyday language, but what is common knowledge to us may be completely alien to our very own audience. not only should libraries be aware of confusing library terms, but content should also not overwhelm the user with an abundance of information. most students who visit the library are looking for something specific and easy to find. it’s important for librarians to condense their information on guides or website pages to not frustrate the user or make them search elsewhere, like google. “students scan. . . rather than [read] material.” 10 this is also something that has been noted from our crazy egg statistics. heatmaps of our website’s pages prove that users are not scrolling to the bottom of the pages. this also applies to the use of large images, or unnecessary flashy or colorful content that covers most of the desktop or mobile screen. these images should be reduced in size so that users can find information swiftly. for this reason, any large design on the homepage should also be included in menu links, in case large flashy content is ignored.11 the search box is also another fundamental element i analyzed. in this case study, our search box was the catalog search box for ex libris primo. if a page, particularly the homepage, has two search boxes—search-all and catalog search—the user can be confused. search boxes are primarily placed at the center of the page. depending on how these search boxes are labeled and identified, users may not know which one to use. students approach library search boxes as if searching google.12 in our case, neither the current website nor the prototype has a general search-all box. we have a catalog search box placed on the top center of the homepage for both sites. if we were to add a general search-all box, it would be placed away from the catalog search box and preferably in the header where it is visible in all pages. methodology the usability study was conducted by the author, the web services librarian at california state university, stanislaus, who also worked with a computer science instructor in order to recruit participants. not only is the university library redesigning its website, but the university library building is also undergoing a physical renovation. due to this project, the library has relocated to the library annex, a collection of modular buildings providing library services to the campus community. the usability study was conducted in a quiet study room in one of these modular sites. i reserved this study area and borrowed eight laptops for the sessions. the usability study employed two different methods to get students to participate. the first offered an extra credit incentive, which was offered when i collaborated with the computer science instructor. this instructor was teaching a course on human-centered design for websites. she offered her students an extra credit incentive, since several of her learning objectives centered on website design and usability studies. the second approach was an informal one. this approach information technology and libraries december 2020 navigation design and library terminology | ochoa 4 was promoted by scouting students who were already at the library annex during the usability study scheduled sessions. this enabled students to participate without having to sign-up or remember to participate. the students were recruited in-person during the usability session and through flyers posted in study rooms on the days of the study. an incentive of snacks for students to take home was also included. i created questions and seven tasks to be handed out to the participants during the study. the tasks were created to test the navigation design of the main menu and content on the homepage. i also added a task to test the research skills of the student. after these tasks, students were asked to rate the ease of access, answer questions about their experience navigating the prototype and to provide feedback. all students were given the same tasks, however if the student was taking the human-centered design course, they were also given specific web design questions for feedback (see appendices a and b). the tasks were piloted before the study with three library student workers who provided feedback on how to better word the tasks for students. the following tasks are the final seven tasks used for the usability study: 1. find research help on citing legal documents—a california statute— in apa style citation. 2. find the library hours during spring break. 3. find information on the library study spaces hours and location. 4. you’re a student at the stan state campus and you need to request a book from turlock to be sent to stockton. fill out the request-a-book form. 5. you are a graduate student and you need to submit your thesis online. fill out the thesis submission form. 6. for your history class, you need to find information on the university’s history in the university archives and special collections. find information on the university archives and special collections. 7. find any article on salmon migration in portland, oregon. you need to print it, email it to yourself, and you also need the article cited. the usability study sessions took place from 11am to 2pm on february 10, 12, and 14, 2020. these days and times were chosen because the snack incentive would attract students during lunch hour and i wanted to accommodate the start and end times of the human-centered design course on mondays, wednesdays, and fridays. the total time it took for students to complete the 7 tasks averaged 15 minutes. in total, there were 38 student participants. the student’s experience was recorded anonymously. i asked students to provide their academic year and major. students ranged from freshman (5), sophomore (2), junior (12), senior (17), graduate (1), and unknown (1). areas of study included computer science (16), criminal justice (2), business (2), psychology (3), communications (1), sociology (1), english (3), nursing (1), spanish (1), biology (3), geology (1), history (2), math (1), gender studies (1), and undeclared (1). the subject tested was the library website prototype created and executed using a springshare llc product, libguides cms. the tools i used were eight laptops and a screen recording tool, snagit. snagit is a recording tool made accessible through a campus subscription. the laptops were borrowed from the library for the duration of the sessions. during the session, students navigated and completed the tasks on their own with no direct interference, including no direct observations. i planned to create a space where my presence didn’t directly influence or intimidate their experience with the website. my findings were based solely on their written responses and screen recordings. i also explained to the students that their screen recorded video information technology and libraries december 2020 navigation design and library terminology | ochoa 5 will not be linked to their identity, since they had to sign-in to the laptop using their campus student id. i did, however, occasionally walk around the tables in the room in case a student was navigating the current website or using a separate site to complete the tasks. once the students completed the tasks and answered the questions, i collected the handouts and the screen -capture videos by copying them to a flash drive. limitations during the usability study session, there were two technical issues that hindered the initial process. on the first day, there were difficulties accessing the campus wi-fi in the room as well as difficulties accessing the snagit video recording application. this limitation affected some of the students' experiences and feedback. these issues were resolved and not present on the second and third day of the study. results and observations the results and observations collected from this study mirror results from the studies conducted by azadbakht and swanson.13 i found that students searched the catalog search box for library collections, citations, and other library terms they didn’t understand, even though it was a catalog search box with the keywords “find articles, books, and other materials” labeled in the search bar. another finding was that the navigation design can detrimentally affect a user's experience with the website. mixed reviews were received from utilizing the audience-based navigation design. the study also found that students are adept at finding research materials. for example, most students knew how to search, find, print, email, and cite an article. students in general are also familiar with book requests, ill accounts, and filling out book request webforms. this indicates that, in terms of utilizing library services, students are well aware of how to find, request, and acquire resources, using the website on their own. what was most difficult for students was interpreting library terminology. this was explicitly shown in their attempts to complete tasks 1 and 6: finding how to cite a legal document in apa style and finding information on special collections and the university archives. the following results and observations are divided into three categories: written responses, video recording observations, and data collected. data was collected based on observations from the video recording and the written responses. data was then input into eight separate charts. written responses observations comments from both non-human-centered website design students and human-centered design students included mixed reviews on the navigation layout, overall positive outlook on the page layout design, suggestions to add a search-all “search bar,” and frustrations with tasks 1 and 6. video recording observations the ex libris primo search box was constantly mistaken as a search-all search box. this occurred during students’ search for tasks 1 and 6: citation help and university archives, respectively. students also used the research guides search box in libguides as a search-all search box. students found the citation style guides easily because of this feature, however on the proposed new website, it was difficult to find citation help. students were also using research guides to complete other tasks, such as task 6. a search bar for the entire website was continuously mentioned as a solution from student participants. information technology and libraries december 2020 navigation design and library terminology | ochoa 6 tasks 2 and 3, regarding library hours and study spaces, were easily completed. tasks 4 and 5 were also easily accessible. after completing task 4 (book request form) it was easier for participants to complete task 5 (thesis submission form) because both tasks required students to search the top main navigation menu. to complete task 4, several students immediately signed-in to their ill account or login to primo for csu+, which was expected as signing-in to these accounts are alternate modes to request a book. an additional other observation, regarding task 4 is that the confusion revolving the library terms, “call number,” was solved by adding an image reference pointing to the call number in the catalog. the call number image reference was opened several times for assistance. most students completed task 7 (find a research article) but not all students used the catalog search box on the homepage to complete it. several students searched the top main navigation and clicked on the “research help” link. others utilized research guides and the research guides search box on the homepage. a particular unique observation was made by some computer science students. most computer science students were quicker to give up on a task as opposed to non-computer science students. some computer science students did not scroll down when browsing pages. these students failed to complete several tasks because they didn’t scroll down the page after being on the page for less than ten seconds. data collected figure 3. ease of navigation (overall). information technology and libraries december 2020 navigation design and library terminology | ochoa 7 figure 3 illustrates the ease of navigation rating overall from all student participants. students were asked to rate the ease of access of the website (see appendices a and b). other than the keywords “ease of navigation (1 difficult; 10 easy)” students were given the freedom to define what “easy” and “difficult” meant to them individually. the mean for the ease of access rating for all student participants was 7.7. the lowest rating of ease of access was 3 and the highest rating of ease of access was 10. figure 4. ease of navigation (computer science major). figure 4 illustrates the ease of access rating by the student participants based on whether the student was a computer science major or not a computer science major. the lowest ease of access ratings were from computer science majors. overall non-computer science majors had higher ease of access ratings than computer science majors. information technology and libraries december 2020 navigation design and library terminology | ochoa 8 figure 5. ease of navigation (human-centered design). figure 5 illustrates the ease of access rating by the student participants based on whether the student was taking the human-centered design course. the human-centered design students’ learning outcomes include website user-interface design and an assignment on how to create a usability study. similar to patterns found in figure 2, human-centered design students had lower ease of access ratings. figure 6. tasks – status of completion. information technology and libraries december 2020 navigation design and library terminology | ochoa 9 figure 6 illustrates whether a task was completed or not. completion of task was determined by analyzing whether or not the student not only found the page(s) that provided the solution to the task. it was determined that a student did not complete the task if the student was unable to find the page(s) that provided the solution to the task. “not applicable” was determined if th e student did not use the website prototype (e.g., followed a link that led elsewhere or opted to use google search instead). most students completed tasks 2, 3, 4, 5, and 7. the task with most “did not complete” was task 1 , which 64 percent of student participants did not complete. task 6 had neutral completion, 63 percent. 86 percent of students completed tasks 2 and 4, and 90 percent of students completed tasks 3, 5 and 7. it is evident that task 1 was a difficult task to complete, regardless of the stu dent’s area of study. task 1 required students to find apa legal citation help. the terms “apa legal citation” confused users. likewise, for task 6 (special collections), students did not understand what “collections” referred to or where to search them. figure 7. tasks – number of clicks (complete). figure 7 illustrates how many clicks it required students to complete the task. the clicks were separated into three categories: 1-2 clicks, 3-5 clicks, and more than 6 clicks. this figure only illustrates data collected from tasks that were completed. the number of clicks began at the website prototype’s homepage or from the main menu navigation found in the website prototype’s header, when it was evident that the student was starting a new task. tasks 2 and 3 were completed in 1-2 clicks, whereas tasks 1, 4, 5, 6, and 7 required an average of 3-5 clicks. because of experience helping students find articles at the librarian's research help desk, task 7 (find research articles) was expected to require 6+ clicks. task 1 may have a pattern of needing a high number of clicks to complete because it was a generally a difficult task to complete. information technology and libraries december 2020 navigation design and library terminology | ochoa 10 figure 8. tasks – number of clicks (did not complete). figure 8 illustrates how many clicks a student participant made before they decided to skip the task or if they believed they had completed the task. this figure only illustrates data from tasks that were not completed. the clicks were separated into three categories: 1-2 clicks, 3-5 clicks, and more than 6 clicks. the number of clicks began at the website prototypes homepage or from the main menu navigation found in the website prototype’s header, when it was evident that the student was starting a new task. task 1 and 6 show the most patterns in this figure. task 1 (citation help) shows that students generally skipped the task after more than 6 clicks. task 6 (special collections) was generally skipped after 3-6+ clicks. figure 9 illustrates the duration to complete each task. the duration was separated into three categories: 0-1 minutes, 1-3 minutes, or more than 3 minutes. this figure only illustrates data for tasks that were completed. the duration began when the student started a new task. this was determined when it was observed that the students started to use the main menu navigation, or if the student directed their screen back to the website prototype’s homepage. there are parallels between the number of clicks and duration of tasks. for tasks 2, 3, and 5, the duration to complete the task was less than 1 minute. task 5 was a task similar to task 4 (both are forms, linked once on the website), but the duration for task 5 may have averaged lower than the duration of task 4, because task 5 was after task 4. having completed a form before task 5 may have influenced the student’s behavior on searching for forms. tasks 1, 6, and 7 averaged 1-3 minutes to complete. information technology and libraries december 2020 navigation design and library terminology | ochoa 11 figure 9. tasks – question duration (complete) figure 10. tasks – question duration (did not complete) information technology and libraries december 2020 navigation design and library terminology | ochoa 12 figure 10 illustrates the duration of each task that wasn’t completed. the duration was separated into three categories: 0-1 minutes, 1-3 minutes, or more than 3 minutes. this figure only illustrates data for tasks that were not completed. the duration began when the student started a new task. this was determined when it was observed that the students started to use the main menu navigation, or if the student directed their screen back to the website prototype’s homepage. similarly, to observations for figure 7, there are parallels between the number of clicks and duration of tasks. for task 1, the average time before students skipped the task varied, however most students who didn’t complete the task skipped it after more than 3 minutes of trying to complete it. for task 6, the average duration before skipping the task was 1-3 minutes. conclusion and recommendations the purpose of this study was primarily designed to test the user-centered study approach and the navigational redesign of the library website. the results, however, provided the library with a variety of outcomes. based on suggestions and comments on the website prototype navigation design, menus, and page content, there are several elements that will be integrated to help lead the redesign of the library’s website. students found that the navigation design of the website was clear and simple, but also required a “getting used to.” because of this, and due to navigation design literature, it is recommended to design a menu navigation that is a topic-based navigation as opposed to an audience-based navigation. our findings also highlighted the effects of the use of library terms. to make menu links exceptionally user-friendly, it is recommended to utilize clear and common terminology. student participants also voiced that a search-all search box for the website was necessary. this will enable users to access information efficiently. library website developers should also map more than one link to a specific page, especially if the only link to the page is on an image or slideshow. the user-centered usability approach for this case study worked well in collaboration with campus faculty and as an informal recruitment. it provided relevant and much needed data and feedback for the university library. in terms of future usability studies, a heuristic approach may be effective. a heuristic study approach will enable moderators to gather feedback and analysis from library web development experts.14 moreover, the usability study could be conducted over a semester long time and include focus groups to acquire consistent feedback. 15 overall, website usability studies are evolving and require constant improvements and research. information technology and libraries december 2020 navigation design and

at the forefront in adopting emerging technologies to manage the library’s operations and provide information services to the user community they serve. with the emergence of cloud computing (cc) technology, libraries are exploring and adopting cc service models to make their own services more efficient, reliable, secure, scalable, and cost-effective. in this article, the authors share their experience migrating some of the library’s locally hosted ict-based services onto the microsoft azure cloud platform. the migration of services to a cloud platform has helped the library significantly reduce the downtime of its services due to power or network or system outages. introduction established in 1909, the indian institute of science is a leading advanced education and research institution in the sciences and engineering. since its inception, the institute has balanced an emphasis on pursuing basic knowledge with applying its research findings for industrial and societal benefit. the institute, which started with just two departments—general and applied chemistry and electrical technology—now has over 40 departments spread across six divisions: biological sciences, chemical sciences, electrical sciences, interdisciplinary research, mechanical sciences, and physical and mathematical sciences. the institute’s jrd tata memorial library (https://library.iisc.ac.in) celebrated its centenary in 2011. established in 1911, the library was one of the earliest central facilities created by the institute to support teaching and research. the library offers both conventional and contemporary services to its users. the library’s traditional services include reference, referral, cataloguing and classification, circulation, inter library loan, document delivery, weekly display of recent periodicals and books, and photocopying. some of the library’s current information and communications technology (ict)based services include digital repository services for the institution’s research publications and theses and dissertations, a faculty profiling system, a web-based online public access catalogue (web opac), and shibboleth-based federated access to the library’s subscribed online resources. the library also facilitates information literacy services such as library orientations, workshops, seminars, demonstrations, invited talks, training sessions on subscribed resources, trial access to new products and services, and author workshops on the research publishing process. mailto:francis@iisc.ac.in mailto:anandtb@iisc.ac.in mailto:filbert@iisc.ac.in https://library.iisc.ac.in/ information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 2 until 2018, the library used its on-premises it infrastructure to provide these ict-based services. the library had dedicated computer servers for its email, institutional repository, library website, integrated library management system (lms), and online journal publishing system. the institution’s faculty profiles system is part of the indian research information system (https://irins.org/irins/), a web-based research information management service provided by the information and library network (inflibnet) centre. the library’s in-house servers were ageing, and they were even beginning to fail. also, managing the in-house servers with limited human resources was increasingly challenging. as a result, the library contemplated moving some of its services to a cloud platform. even smaller libraries had begun migrating their services to the cloud platform almost a decade ago.1 around 2016, the institution established the digits (digital campus and information technology services) office to conceive, plan, and create a best-in-class information technology and networking system and support operational excellence through agile it and networking services. to date, the digits office has, among other projects, successfully migrated more than 70 departmental email servers to a centrally managed cloud-based microsoft office 365 suite and developed and migrated the institute’s main website (https://www.iisc.ac.in) and more than 150 websites and 10 web portals of institution departments, centres, and other facilities to the microsoft azure platform. the digits office also creates and maintains virtual machines (vms) on the microsoft azure cloud platform for the institution’s departments and offices. migration of locally hosted it infrastructure to a cloud platform offers several benefits to the organization. these benefits include setting up virtual offices accessible from anywhere and at any time, avoiding capital investment in computing infrastructure, taking advantage of the cloud platform’s elastic computing resources, avoiding the necessity of having a dedicated it team, and, most importantly, minimizing downtime and loss of productivity and data. moreover, a cloud platform offers easy scalability, redundancy, and security. achieving these features in the traditional in-house hosting of computing infrastructure would be cost prohibitive. 2 the library has configured three vms on the azure platform and has moved some of its ict-based services to the cloud platform. migrating ict-based services to the cloud platform has helped the library significantly reduce the downtime of computer servers. cloud computing and its service models cloud computing (cc) refers to computer hardware and software provided as a service by another company. the only requirement to access the cloud computing service is a device with access to the internet. some leading cc service providers include amazon web services (https://aws.amazon.com/what-is-aws/), microsoft azure (https://azure.microsoft.com/en-in/), and google cloud (https://cloud.google.com). there are three service models in cloud computing: software as a service (saas), platform as a service (paas), and infrastructure as a service (iaas). service providers host software applications on their cloud platforms in the saas model. examples of the saas model include google apps (https://workspace.google.com/) and microsoft office 365 (https://www.microsoft.com/enin/microsoft-365). clients opting for the saas model need not worry about installation, setup, running, and maintaining the applications. service providers will do that for the clients. https://irins.org/irins/), https://www.iisc.ac.in/ https://aws.amazon.com/what-is-aws/ https://azure.microsoft.com/en-in/

migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 3 paas provides a computing platform comprising an operating system, database, programming environment, and application programming interface. examples of the paas model include amazon elastic beanstalk (https://aws.amazon.com/elasticbeanstalk/), windows azure (https://azure.microsoft.com/en-in/), and google compute engine (https://cloud.google.com/compute). in the iaas service model, clients can obtain computing infrastructure, virtual machines, networking, and storage components on demand and deliver them over the internet. examples for the iaas model include google compute engine, amazon ec2, and microsoft azure. in coordination with the digits office, the library initially provisioned three vms on the microsoft azure cloud platform to migrate some of its it-based services. table 1 shows the initial hardware configurations of each of the three vms. table 1. vm types and their system configurations along with the cost virtual machine (vm) vm type1 vcpus & ram (gb) cost / month (usd)2 os disk (gb) & type secondary storage disk (gb)

scalable computing resource available on cc platforms. vms give better control over the computing environment without buying any underlying physical hardware. the microsoft azure platform offers various vm options, each optimized for different workloads. for example, the d-series azure vms provide a combination of vcpus (virtual cpus), memory, and temporary storage to meet the requirements associated with most production workloads. categories in the d-series of vms include ds-series, dds-series, and das-series. the f-series vms feature a higher cpu-to-memory ratio, are equipped with 2 gb ram and 16 gb of local solid-state drives (ssds) per cpu core, and are optimized for compute-intensive workloads. f-series vms are costlier than the corresponding d-series vms (https://docs.microsoft.com/en-us/azure/virtualmachines/sizes). for the secondary storage, apart from the standard hard disk drives (hdds), vms support azure premium ssds and ultra-disk storage, depending on regional availability. the premium ssds are designed to support intensive input/output workloads. they are priced almost three times higher than the standard hdds. the standard disk capacity of an azure vm’s os disk is 30 gb, and it can be increased to the desired capacity. apart from the os disk, one can also have a required amount of secondary disk storage. the cost for the additional disk storage (both os and data) is https://aws.amazon.com/elasticbeanstalk/ https://azure.microsoft.com/en-in/ https://cloud.google.com/compute

library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 4 independent of vm pricing, and it depends on storage type and capacity. a vcpu refers to a virtual central processing unit. a vm treats each vcpu as a single physical core. migration of the library’s ict-based services to microsoft azure cloud platform libraries have always been at the forefront of adopting emerging technologies. it is true with cc technology as well. in an interview at the american library association annual meeting in anaheim, california, in june 2012, clifford lynch traced 30 years of interactions between libraries and new technologies.3 with the evolution of cc technologies, libraries have been using cc’s saas and iaas service models since 2009 to host their websites, library management system (lms), and digital repositories. libraries have been using the cc mainly for saas and iaas services.4 as a first step, during mid-2017, the digits office began migrating all the 70+ individual departmental email servers, including the library’s, to a centrally managed, cloud-based mailing solution using office 365 (now microsoft 365) exchange online. after the successful migration of all the email servers, the library shut down its email server. next, the library decided to migrate some of its locally hosted ict-based services to the cloud platform in a phased manner. planning the migration process: considering a single vm or independent vms for each application before undertaking the migration process, libraries need to consider what types of projects are good candidates for the cloud and what types are not.5 in the first phase of the cloud migration, the library decided to migrate the following services: (1) institutional repository services, (2) the library management system, and (3) the library website. before the cloud migration, the library used three independent on-premises servers to host the above services. a sun fire computer server with intel xeon processor, 4 gb of ram, and 2 tb of secondary storage hosted the institutional repository service for research publications using eprints software and the electronic theses and dissertations service using dspace software. the libsys library management system was hosted on an ibm server with intel xeon cpu e5-2620 v2 @ 2.10ghz processor, 16 gb ram, and 1 tb of secondary storage. the library website was hosted on an ibm thinkserver ts150 server with intel xeon cpu e3-1225 v5 @ 3.30ghz processor, 8 gb ram, 1 tb of secondary storage. all three computer servers had been in use for nearly 10 years and were long overdue for replacement. as the library contemplated upgrading its ict infrastructure, provisioning vms on the azure cloud platform through the digits office was a stimulus. next, the library had to decide whether to go with a single vm with robust hardware configuration to host all three applications or to provide independent vms for each service. based on the experience gained from hosting two ir services on a single server, the library decided to go again with a single vm with robust hardware configuration to host the ir services. the lms is a critical application for managing all library functions; therefore, the library decided to host it on a separate vm. a third vm is used to host the library website. as the library eventually plans to move its other ict-based applications to the azure platform, it could migrate and distribute those applications on the existing three vms based on the utilization and load on each of the three vms. initially, the library opted for two vms in the f-series and one in the d-series with premium ssds for all three vms. after observing performance and price for about three months, the library had information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 5 one of the two vms (vm3) moved from f-series to d-series and downgraded the os and data disk types of all the three vms to the standard disk drives. the data disk on vm3, hosting the library website, was dropped as the os disk capacity was more than adequate to run the service. table 2 shows the revised vm types and their configurations. in april 2020, most of our students and faculty members started working off-campus because of the onset of the covid-19 pandemic. to facilitate seamless access to licensed online resources from off-campus, the library set up federated access through shibboleth sso.6 the library provisioned a new virtual machine (vm4) with a system configuration as indicated in table 2. table 2. revised vm types and their system configurations along with the cost virtual machine (vm) vm type4 vcpus & ram (gb) cost/

onpremises computers to a cloud platform. before undertaking the migration process, the requisite software applications must be installed and configured on the vms. then, the data corresponding to each application must be backed up on the on-premises system and moved to the corresponding vms. coordination with the campus network support team is essential to ensure the vms are accessible on the internet with all the security measures in place. so, every application migrating to the cloud platform has to go through a cloud migration process. in the following sections, the authors briefly describe the library’s migration process to migrate three of its ict-based services to the azure cloud. the library completed the entire migration process in about three months. migration process for the research publications repository eprints@iisc, the institute’s institutional repository (ir), was established in 2002 and holds nearly 55,000 publications. it is one of the earliest repositories in this part of the world. 7 the ir runs on eprints (https://www.eprints.org/uk/), the world-leading open-source digital repository platform. developed at the university of southampton for over 20 years, eprints has provided stable, innovative repository services across academia and beyond. eprints is a stable, flexible, https://www.eprints.org/uk/ information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 6 reliable software and ideal for maintaining institutional repositories. before the migration, the library hosted the publications repository on an on-premises server for almost 17 years. eprints software depends on other software, including apache web server with mod_perl (https://httpd.apache.org/), mysql/mariadb (https://mariadb.org/) relational database management system, perl programming language, and several perl modules. eprints software bundles many required perl modules, but some are installed depending on the underlying operating system (os). for example, for the eprints@iisc repository installed on a vm running the cent os, the library has installed apache web server with mod_perl, mariadb relational database management system, and a few missing perl modules. after installing all the dependent software, the library followed the steps listed below to migrate the publications repository to the vm on the azure cloud platform: 1. installed the latest version of the eprints (3.4.1) software on the vm and incorporated all the local customizations done at the configuration and code levels. 2. created a new repository and retained the existing repository name. 3. created a new mariadb database and assigned appropriate grant permissions to the database. 4. as the database structure had changed in the latest version of eprints, executed the necessary scripts built into the eprints software to update the eprints database structure. 5. imported customized institute-specific subject headings to override the default ones. 6. moved the database and full-text backup files to the vm using winscp—an open-source, free ftp client (https://winscp.net/eng/docs/introduction). 7. restored the backups comprising eprints mysql database and full-text files on the vm to the corresponding locations on the file system and uncompressed database and full-text files. 8. imported the mysql database into the new mariadb database on the vm. 9. regenerated all the static pages of the repository, abstracts of all the records, and browse views for the year, author, document type, and subject categories on the vm. 10. enabled hypertext transfer protocol secure (https) for log in and account creation links. 11. configured postfix (http://www.postfix.org/). postfix is a free and open-source mail transfer agent that routes and delivers electronic mail. 12. coordinated with the institute’s network support team to make necessary changes in the dns entries to reflect the vm’s new public ips and enable the vm to send and receive emails. 13. created crontab entries on the vm to run the cron jobs. a cron job is a time-based job scheduler in a unix-like computer operating system. some of the cron jobs include updating the latest records added to the repository, displaying the latest count of records in the repository, and updating the browse views of the repository. migration process for the electronic theses and dissertations repository established in 2005, etd@iisc, the institution’s electronic theses and dissertations repository, is one of the earliest etd repositories in this part of the world. 8 the library uses dspace software (https://duraspace.org/dspace/) to maintain the etd repository. to date, the repository holds nearly 6,000 of the institute’s etds. before the migration, the library hosted the etd repository on an on-premises server for almost 13 years. https://httpd.apache.org/

ict-based services to a cloud platform | jayakanth, byrappa, and minj 7 dspace software is dependent on several third-party software applications and tools, including java jdk, apache maven (https://maven.apache.org/), apache ant (https://ant.apache.org/), postgresql (https://www.postgresql.org/) or oracle (https://www.oracle.com/in/database) relational database management system, and apache tomcat servlet engine (http://tomcat.apache.org/). the library followed the steps listed below to migrate the etd repository to the vm on the azu re cloud platform: 1. installed all the dspace-dependent software packages and the latest version of dspace software (version 6.3). 2. configured the dspace software to incorporate the native customizations. 3. created communities and collections to reflect the divisions and the corresponding departments and centres of the institute using java script. 4. set the access permission for each collection of the repository based on the users and groups belonging to the collection. 5. modified the metadata of the etds from the on-premises version using a script. the modified metadata was imported into the latest version of dspace. 6. copied and moved etd items comprising pdf files from the on-premises server to the vm. 7. enabled hypertext transfer protocol secure (https) for the etd site. 8. customized the default etd site for a better look and feel. 9. created crontab entries on the vm to run the cron jobs to take incremental backup and display the etd count on the landing page. the new version of the dspace user registration system was modified to enable only people with an institute email id to register with etd@iisc. in addition, the registration process captures the registrant’s department and the division, which helps automate the process of assigning the registrant to a specific collection of the repository. therefore, a user will submit an etd only to the designated collection. migration process for the libsys library management system the library has been using libsys (https://www.libsys.co.in/), a commercial lms, for over 25 years. libsys is dependent on several other software applications, including wildfly application server (https://www.wildfly.org/), java jdk, and mysql (mariadb) relational database management system. the steps involved in migrating libsys to the cloud (vm2) are listed below: 1. installed all the libsys-dependent software components and the latest version of the libsys software on the vm. 2. restored the mariadb database backup. 3. made required changes in the libsys configuration files. 4. installed and configured postfix email transfer agent for email communication. 5. as the libsys service and the opac run on nonstandard ports, the library coordinated with the network support team to open the required communication ports on the vm. https://maven.apache.org/ https://ant.apache.org/ https://www.postgresql.org/ https://www.oracle.com/in/database http://tomcat.apache.org/ https://www.libsys.co.in/ https://www.wildfly.org/ information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 8 migration process for the library website the library uses drupal (https://www.drupal.org/), a content management system, to host its website. the steps involved in the migration process are listed below: 1. installed all the drupal-dependent software, including apache web server, mariadb, and php (https://www.php.net/), on the vm. 2. installed one of the latest versions of drupal using its web-based installer. 3. installed the required drupal plugins and the drupal theme. 4. restored drupal database backup on the vm. 5. installed and configured postfix email transfer agent for email communication. after completing migration processes, the library coordinated with the network support team to make changes in the domain name system (dns) to enable access to all the three vms on the internet. monitoring the azure virtual machines azure monitor (am) for vms includes a set of performance charts that target several key performance indicators to determine how well a virtual machine performs. the graphs show resource utilization over a period to identify bottlenecks and anomalies or switch to a perspective listing of each vm to view resource utilization based on the metric selected. while there are numerous elements to consider when dealing with performance, azure monitor for vms monitors critical operating system performance indicators related to the processor, memory, network adapter, and disk utilization. performance complements the health monitoring feature and helps expose issues that indicate a possible system component failure, support tuning and optimization to achieve efficiency, or support capacity planning (https://docs.microsoft.com/enus/azure/azure-monitor/insights/vminsights-performance). am is accessible only to the cloud administrator. based on the am charts, the library’s inference has been that the ir server (vm1) hosting publications and etd repositories needs capacity planning. cpu utilization is reaching maximum capacity quite frequently. therefore, the library plans to move the etd repository to an independent vm. the utilization of the ilms server (vm2) is less than optimal. therefore, the library decided to migrate publication of the institution’s journal of the indian institute of science (jiisc) from onpremises hosting to the ilms server (vm2) on the azure cloud. for hosting jiisc on the azure cloud platform, the library uses the open journal system (ojs) platform (https://pkp.sfu.ca/ojs/). ojs is open-source software for the management of peerreviewed academic journals. ojs is dependent on other software and tools, including apache web server, mysql or postgresql, and php. the library used the virtual hosting concept to host multiple sites on a single vm (vm2). virtual hosting is a method of hosting multiple domain names on a single server. https://www.drupal.org/ https://www.php.net/ https://docs.microsoft.com/en-us/azure/azure-monitor/insights/vminsights-performance https://docs.microsoft.com/en-us/azure/azure-monitor/insights/vminsights-performance https://pkp.sfu.ca/ojs/ information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 9 benefits observed of migrating to the cloud moving some of the ict-based services of the library to the azure cloud platform has resulted in the following benefits: 1. service reliability has improved significantly as the reliance on the in-house ageing servers has been done away with. 2. cloud migration has made the library’s computing infrastructure more flexible. it can be scaled up or down as per the library’s requirement. 3. operational logs and usage metrics are easy to obtain. 4. set alert rules are based on vm metrics. 5. the cloud hosting company’s managed services include periodic backups, ensuring that data is secure. 6. users can now quickly move between the library and home (or any other location) and access all their research. 7. another significant benefit to cloud computing for library users is sharing information easily. libraries provide collaborative spaces within the building, but patrons also can use collaborative online spaces. onedrive provides access to online storage and allows sharing of files and folders among approved users. 9 lessons learned during and after the migration process initially, the library opted for two vms on azure’s f-series and one in the d-series with the ssd storage devices for all three vms. as stated above, the pricing of the azure vms depends on the hardware configuration of a specific type of vm series. for example, the f-series with a particular hardware configuration and ssd costs more than its counterparts on the dor b-series with the same hardware configuration with a standard hdd. libraries should, therefore, have a clear understanding of the vm types and the corresponding costing aspect. after observing vms performance and the cost aspect for a few months, the library moved one of the two vms from the f-series to the d-series and switched to standard hard disk drives for all three vms. the changeover did not result in any performance degradation, but the cost of the secondary storage came down by about one-third. the library maintains two institutional repositories, one for research publications using the eprints application and the other for theses and dissertations using the dspace application. the library decided to migrate both the repositories to a single vm. however, it turns out that this decision was not a prudent one, for the tomcat server running eprints crashes, often resulting in downtime for the etd service. the vm usage metrics reveal that the dspace application often utilizes nearly 100% of cpu capacity, which leads to the freezing of the tomcat server, resulting in etd service becoming unresponsive. the library contemplates upgrading the hardware configuration or setting up the two repository applications on two vms. the library is checking to understand if the issue is with the tomcat server configurations. the graph shown in figure 1 is the screenshot of azure’s metric monitoring of the vm1 running eprints and dspace applications. the peaks in the graph represent the cpu usage by the dspace application. it is evident from the graph that quite frequently, the cpu usage of the dspace application is reaching 100%, which eventually leads to the freezing of the tomcat web server. information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 10 figure 1. screenshot representing the cpu usage of eprints and dspace applications. the professional library staff administered and managed the on-premises ict-based services of the library. therefore, the library did not encounter any technical challenges during and after the cloud migration process. other libraries that intend to migrate their services to a cloud platform should ensure that the library staff entrusted with the migration process are comfortable working with the command prompt, especially in the linux operating system environment. conclusions it has been more than two years since some of the library’s ict-based services migrated to the microsoft azure platform. to date, the library has not experienced a single instance of its servers being down because of a power outage, network issue, or crashing of the vms. however, there have been issues with specific services like the apache tomcat servlet engine or the apache web server crashing, resulting in the corresponding application being unresponsive. such behaviour can result because, at times, the system resources, especially the cpu and ram, may be used to their capacity. restarting the specific service will ensure that the corresponding application comes up. therefore, it is essential to keep track of the ram and cpu usage of the vms and upgrade them if the situation warrants such an action. the rapid elasticity characteristic of cloud computing facilitates organizations to configure optimal computing resources based on actual requirements. based on the library’s initial experience running the ict-based services on a cloud platform, the authors suggest that deploying two different institutional repository software platforms like eprints and dspace on a single vm may not be a good idea. the tomcat instance powering the dspace site runs with higher cpu usage, swinging up to 100% and at times going beyond 100% cpu usage. the high cpu usage by the tomcat instance can eventually lead to its freezing, resulting in the corresponding service being inaccessible. working with the vms demands some degree of familiarity in working in the command prompt. library staff who are not comfortable working in the command prompt will require additional training in getting used to the vm environment. in our case, the training was not necessary as the authors had adequate experience working in the linux operating system. also, library staff managing the cloud infrastructure need to coordinate with the organization’s networking and information technology and libraries march 2022 migration of a research library’s ict-based services to a cloud platform | jayakanth, byrappa, and minj 11 email support staff to configure the vms to be accessible on the internet, email communications , and

respectively, have been distribttted through various lc publications. due to the importance of the two documents, however, and to the fact that they may not have reache.d the entire libtary community, it seemed therefore appropriate to publish the papers again in journal of library automation. sharing machine-readable bibliographic data: a progress report on a series of meetings sponsored by the council on library resources beginning in december 1972 and continuing since that date, the council on library resources has convened a series of meetings of representatives of several organizations to discuss the implications of bibliographic data bases being built around the country and the possibilities of sharing these resources. although the deliberations are not yet completed, the council, as well as all participants in the meetings, felt that it was timely to make the progress to date known to the community. since publication in the 58 i ournal of library automation vol. 7/1 march 197 4 open literature implies a long waiting period between completion of a paper and the actual publication date, it was decided that this paper should be written and distributed as expeditiously as possible. since the library of congress has vehicles for dissemination of information in its marc distribution service, i nfotmation bulletin, and cataloging setvice bulletin, lc was asked to assume the responsibility for the preparation of a paper to be distributed via the above mentioned channels as well as sending copies to relevant associations. the institutions participating in the deliberations have been included as an appendix to this paper. the bibliographic data bases under consideration at individual institutions contain both marc records from lc as well as records locally encoded and transcribed. these local records represent: ( 1) titles in languages not yet within the scope of marc; (2) titles in languages cataloged by lc prior to the onset of the marc service; ( 3) titles not cataloged by lc; and ( 4) titles cataloged by lc and recataloged when the lc record cannot be found locally. the first two categories, in many instances, are being encoded and transcribed by institutions using lc data as the source, i.e., proofsheets, nuc records, and catalog cards. these are referred to for the remainder of this paper as lc source data and the third and fourth categories as original cataloging. all participants agreed that the stmcture of the format for the interchange of bibliographic data would be marc but several participants questioned if a subset of lc marc could not be established for interchange for all transcribing libraries other than lc. 1• 2 although lc had reported its survey regarding levels of completeness of marc records and the conclusions reached by the recon working task force, namely, "to satisfy the needs of diverse installations and applications, records for general distribution should be in the full marc format," it appeared worthwhile to once more make a survey to see if agreement could be reached on a subset of data elements. 3 the survey ineluded only those institutions participating in the clr meetings. the result of the survey again demonstrated that considered collectively, institutions need the complete marc set of data elements. the decision was made that the lc marc format was to be the basis of the further deliberations of the participants. attention was then turned to any additional elements of the format or modifications to present elements that may be required in order to interchange bibliographic data among institutions. all concmned recognized that although networks of libraries, in the true sense, still do not exist today, much has been learned since the development of the marc format in 1968. certain ground rules were established and are given below: 1. the material under consideration is to be limited to monographs. 2. the medium considered for the transmission of data is magnetic tape. 3. data recorded at one institution and transmitted to another in machinereadable form is not to be retransmitted by the receiving institution as part of the receiving institution's data base to still another institution.4 4. any additions or changes required to the marc format for "networking" arrangements are not to substantially impact lc procedures. 5. any additions or changes required to the marc format for "networking" arrangements are not to substantially affect marc users. long discussions took place concerning modifications to lc source data by a transcribing library and the complexity involved in transmitting information as to which particular data elements were modified. ground mle 6 was established stating that if any change is made to the bibliographic content of a record copied from an lc source document (other than the lc call number), the transcribing library would be considered the cataloging source, i.e., the machine-readable record would no longer be considered an lc cataloging record. any errors detected in lc marc records are to be reported to lc for correction. a subcommittee was formed to study what marc format additions and modifications were required. the subcommittee met on several occasions and made the following proposals to the parent committee: 1. fixed field position 39 and variable field 040, ·cataloging source, should be expanded to include information defini.ng the cataloging library, i.e., the hbrary responsible for the cataloging of the item, and the transcribing library, i.e., the library actually doing the input keying of the cataloging data. 2. lc should include the lc card number in field 010 as well as in field 001. when the lc card number is known by an agency transcribing cataloging data, field 001 should contain that agency's control number and field 010 should contain the lc card number. 3. variable field 050 should not be used for any call number other than the lc call number. transcribing agencies should always put the lc call number in this field if known. 4. a new variable field 059, contributed classification, should be defined to allow agencies other than lc to record classification numbers such as lc classification, dewey, national agricultural library classification, etc., with indicators assigned to provide the information as to what classification system was recorded and whether the cataloging or transcribing agency provided this data. 5. variable field 090, local call number should follow the same indicator sys~ tern as defined in field 059. (090 contains the actual call number used by either the cataloging or transcribing library while 059 would contain additional classification numbers assigned by the cataloging or transcribing library.) 6. lc would assume the responsibility of distributing any agreed upon additions or modifications as either an technical communications 59 addendum to or a new edition of books: a marc format. discussions following the presentation of these proposals indicated concern regarding three principal areas: 1. the modifications of any data element in an lc source document other than the addition of a local call number dictated that the institution performing the modification of the record assume the position of the cataloging source. this resulted in the possibility that a large number of records would undergo minor changes and consequently the knowledge that the record was actually an lc record would be lost. this loss was considered a critical problem. 2. the creation of a marc record implied that each fixed field and all content designators should be present if applicable for any one record. during the lc recon project, it was recognized that certain fixed fields could not be coded explicitly because the basic premise in the recon effort was the encoding of existing cataloging records without inspecting the book. consequently, the value of certain fixed fields such as indicating the presence or absence of an index in the work, could not be known. participants felt that a "fill" character was needed to describe to the recipient of machiner~adable cataloging data that a particular fixed field, tag, indicator, or subfield code could not be properly encoded due to uncertainty. the "fill" character will be a character in the present library character set but one not used for any purpose up to this time. 3. although networking is not clearly defined at this time, participants felt that the marc format should have the capability to include location symbols to satisfy any future requirement to transmit this information in order to expedite the sharing of library resources. majority opinion indicated there was a 60 journal of library automation vol. 7/1 march 1974 need to guarantee the recognition of an lc source record, that a "fill" character could serve a useful function, and that a method of transmitting location symbols was required. three position papers were written on the topics outlined above giving the rationale for the requirement and describing a proposed methodology for implementation. these papers were reviewed at a meeting of the participants and are presently undergoing modification taking into account recommendations made. the revised papers are to be distributed prior to the next meeting in january 1974. following this meeting, another paper will be prepared for publication which will include a definitive account of the modifications and additions recommended for the marc format as well as describing the rationale for the additions and modifications. at that time the proposals will be submitted to the library community for its review and acceptance. if the additions and changes are approved by the marbi5 committee of the american library association, lc will proceed to amend or rewrite the publication books: a marc format. however, the points elaborated below deserve emphasis toward the understanding of the issues described in this paper. 1. the meetings were concerned with a national exchange of data, not international. 2. the additions and modifications recommended for the marc format, with one exception, affect organizations other than the library of congress exchanging machine-readable cataloging data. except for distributing records with the lc card number in field 010 as well as 001, the marc format at lc will remain intact. 3. lc will investigate the use of the fill character in its own records, both retrospective and current, and for records representing all types of materials. henriette d. avram marc development office library of congress references 1. the marc format has been adopted as both a national and international format by ansi and iso respectively. 2. subset in this context includes· both the data content of the record (fixed and variable fields) and content designators (tags, indicators, and subfield codes) . 3. recon working task force, "levels of machine-readable records," in its national aspects of creating and using marc/recon reco1'ds (washington, d.c.: library of congress, 1973), p.4-6. 4. this rule did not extend to a subscriber to the lc marc service duplicating an lc tape for another institution. one can readily see the chaos that would result if institution a sent its records to institutions b and c, b then selected all or part of a's records for inclusion in its data base, and then transmitted its records to a and c. the result of the multitransmission of the same records, modified or not, would create useless duplication and

stanford university libraries university of chicago libraries washington state library university of western ontario library a composite effort to build an on-line national serials data base (a paper for presentation at the arl midwinter meeting, chicago, 19 january 1974) an urgent requirement exists for a concerted effort to create a comprehensive national serials data base in machine-readable form. neither the national serials data program nor the marc serials distribution service, at their current rate of data base building, will solve the problem quickly enough. because of the absence of a sufficient effort at the national level, several concerted efforts by other groups are under way to construct serials data bases. these institutions have been holding in abeyance the development of their automated serials systems, some for several years, waiting for sufficient development at the national level to provide a base and guidance for the development of their individual and regional systems. this has not been forthcoming, and local pressures from their users, their administrators, and their own developing systems are forcing these librarians to act without waiting for the national effort. these efforts are exemplified by the work of one group of librarians, described below. what has now come to be known as the "ad hoc discussion group on serials" had its beginnings in an informal meeting during the american library association's conference in las vegas last june. you will also hear this discussion group referred to as the "toronto group." this is because its prime mover has been richard anable of york university, toronto, and because the first formal meeting occurred in that city. the expenses of the toronto and subsequent meetings have been borne by the council on library resources, and council staff have been involved in each meeting. a fuller exposition of the origins, purposes, and plans of the toronto group has been written by mr. anable for the journal of libm1'y automation. it appeared in the december 1973 issue. quoting from anable: "at the meeting [in las vegas] there was a great deal of concern expressed about: 1. the lack of communication among the generators of machine-readable serials files. 2. the incompatibility of format and/ or bibliographic data among existing files. 3. the apparent confusion about the technical communications 61 existing and proposed bibliographic description and format 'standards'." end of quote. the toronto group agreed that something could and should be done about these problems. if nothing else, better communications among those libraries and systems creating machine-readable files would allow each to enhance its own systems development by taking advantage of what others were doing. as the discussions progressed, several points of consensus emerged. among them were: 1. the marc serials distribution service of the library of congress and the national serials data program together were not building a national serials data base in machine-readable form fast enough to satisfy the requirements of developing library systems. this systems development was, in several places, at the point where it could no longer wait on serials data base development at the national level as long as progress remained at the current rate. 2. the marc serials format developed at lc offered the only hope for machine format capability. every system represented planned to use it. for the purpose of building a composite data base outside lc, the marc serials format would probably require minor modification, principally by extension. these extensions could and should be added on so as to do no violence to software already developed to handle marc serials. 3. there existed some difference between the lc marc serials format and that used by the national serials data program. these differences arose from several circumstances. for example, the marc serials format predated the international serials data system (isds), the national serials data program, and the key title concept. when these three came along, the requirement existed that the nsdp abide by the conventions of the isds. since the key title 62 journal of librm·y automation vol. 7/1 march 1974 is not yet a cataloging title, but is the title to which the international standard serial number is assigned, it is natural that the approach to serial record creation by nsdp should be different from that of a library cataloging serials by conventional methods. a working group under the auspices of the ifla cataloguing secretariat has devised an international standard bibliographic description for serials. the working group's recommendations are to be distributed for trial, discussion, and recommendation for change in february. when the isbd ( s) is accepted into cataloging practice, some of the differences in marc usage and nsdp procedure will disappear. others will still remain and they must be reconciled. we cannot continue with two serial records, both of which claim to be national in purpose but which are incompatible with each other. a good exposition of the differences in these serials records from the point of view of the marc development office is in an article by mrs. josephine pulsifer in the december 1973 issue of the journal of libmry automation. 4. major canadian libraries are active in cooperative work on serials and these two national efforts should be coordinated. several other circumstances bear on the problem. for example, the national serials data program is a national commitment of the three national libraries. in addition to the funding from the three national libraries, there are excellent chances that the nsdp will receive funds from other sources to expedite its activities. the nsdp is responsible for the issn and key title and for relationships with the international serials data system. ultimately, the issn and key title will be of great importance to serials handling in all libraries. for all of these reasons it is imperative that the activities of the nsdp be channeled into the comprehensive data base building effort described in this paper. when it was realized at the council on library resources that the toronto group was serious and that a data base building effort would result, it was obvious that this had enormous significance for the library of congress and other library systems because the result would be a de facto national serials data base. accordingly, a paper was prepared and sent to lc, urging that an effort be made in washington to coordinate the efforts of the marc serials distribution service, the national serials data program, and this external effort. in addition, it was felt that lc should take a hard look at its own several serials processing flows and attempt to reconcile them better with each other and with the external effort. to do this, lc was urged to do a brief study of lc serials systems, using lc staff and one person from clr. lc agreed and the study is now very nearly complete. the written guidance given the study group members was quite specific. they were to study all serials flow at lc and make their recommendations based on what lc should be doing, rather than being constrained by what lc is doing. the overall objectives of the study were to aim for the creation of serials records as near the source as possible and onetime conversion of each record to machine-readable form to serve multiple uses. specifically to be examined were the serials processing flows of the copyright office, the order division, the serial record division, new serials titles, and the national serials data program. while all of this was going forward, the toronto group had some more meetings. oclc was tentatively selected as the site for the data base building effort. it is understood by everyone that this is a temporary solution; eventually a national-level effort must be mounted which will provide a post-edit capability to bring the composite data base up to nationally acceptable standards. a permanent update capability is also required. this permanent activity, hopefully, will be based at the library of congress. oclc was chosen as the interim site for several reasons, but especially for its proven capability to produce network software and support which will work. within a very short time oclc will have on-line serials cataloging and input capability which will extend to some two hundred libraries. no other system is nearly so far advanced. the toronto group has assured itself that the data record oclc intends to use is adequate and is now working on the conventions required to insure consistency in input and content, to include some recommendations for minor additions to the marc serials format. during their deliberations, the toronto group realized that, to be effective, their efforts needed formal sponsorship, and discussions to this end were begun. initially, several agencies were considered to be candidates for this management role. various considerations quickly narrowed the list down to the library of congress, the association of research libraries, and the council on library resources, and representatives of these three met to discuss the matter further. during the discussions, clr was asked to assume the interim management responsibility until a permanent arrangement could be worked out. clr was selected because, as an operating foundation under the tax laws, it can act expeditiously in matters of this kind. clr can also deal with all kinds of libraries and has no vested interest in any particular course of action. meanwhile, certain institutions in the toronto group had indicated that they were ready to pledge $10,000 among themselves for the specific purpose of hiring mr. anable as a consultant to continue his coordinating activities. the group asked clr to act as agent to collect and disburse these funds. clr is ready to assume the initial responsibility for the management of this cooperative data base building effort, if that is the will of the leadership in the library community. clr is prepared to commit one staff member full time to the project who is well versed in the machine handling of marc serials records. this is mr. george parsons, and other staff members will assist as appropriate. mr. anable has agreed to act as a consultant to help coordinate these activities. clr would aim for the most complete, accutechnical c01nmunications 63 rate, and consistent serial record in the lc marc serials format which can be had under the circumstances. during the effort, clr will act as the point of contact between oclc and the participating libraries, assisting in negotiating contracts and other agreements as required. the composite data base will be made available to all other libraries at the least possible cost for copying. initially at least, the costs of this effort will have to be shared by the participating libraries, since no additional funds are presently available. the goal is to build 100,000 serial records the first year, another 100,000 the second year, and design and implement the permanent mechanism the third year, while file-building continues. as the project gets under way, it will work like this: a set of detailed written guidelines for establishing the record and creating the input will be promulgated, and agreement to abide by them will be a prerequisite to participation. selected libraries with known excellence in serial records will be asked to participate; others may request participation. those selected who already have or can arrange for terminals on the oclc system will participate on line. this is the preferred method, but it may be possible to permit record creation off line, such records to be added to the data base in a batch mode. it is very difficult to merge serial files from different sources in this way, so an attempt will be made to find a large serials data base in machine-readable form for use as a starting point. this file would be read into the oclc system. a participating library wishing to enter a record would first search to see whether it existed in the initial data base. if a record is found, it would be updated insofar as this is possible, within the standards chosen for the system. it may be further updated by other participants, still within the system standards, but at some point update on a record in the system will reach a point of diminishing returns and the record will remain static until a post-edit at the national level can be performed. these records will be for use as their recipients see fit, but their prime purpose is to support the development of automated serials sys64 journal of library automation vol. 7/1 march 1974 terns while eliminating duplication of effort. details of how to hag these records in the oclc data base as they are being created by this effort will be worked out, as will be the relationship between this effort and the rest of oclc activities. clr will, from time to time, report progress to the community. it would be the hope of clr that the toronto group will continue to assist in the technical and detailed aspects of the project. in addition, and after consultation with the appropriate people, an advisory group will be appointed to advise clr in this effort. lawrence living8ton council on library resou1'ces input to the editor: re: file convm·sion using optical scanning at berkeley and the university of minnesota discussed by stephen silber8tein, jola technical communications, december 1973. it is rewarding to find someone who has actually read in detail one's published work (grosch, a. n. "computer-based subject authority files at the university of minnesota libraries"), i generally agree with mr. silberstein's observations regarding the use of optical scanning for library file conversion. however, several points were raised by mr. silberstein on which i feel further comment is needed. perhaps in my article i should have cautioned the reader that when developing procedure and programs for the cdc 915 page reader, there is a great variance in these machines depending upon: 1. how early a serial number unit, i.e., vintage of machine, 2. what version of the software system grasp is being used, 3. what degree of machine maintenance is performed out, and 4. what kinds of other customers are using the scanner. it was our misfortune to have a cdc 915 page reader that had many peculiarities about it which could or would not be resolved by a maintenance engineer. in addition it was not heavily used and what use it did receive was mostly nonrepetitive conversion jobs dealing mostly with mailing address file creation and freight billing. in our initial testing we tried to use various stock bond paper and had various reading difficulties. in talking with others who had used this particular machine we found that the choice of paper stock was critical on this scanner. i might add that we did not actually use $400 worth of paper on this as i sold half of the stock we had ordered to another user locally who was going to use this device. it might be worth mentioning that we had a failure of a potentially large conversion project reported to us. this project tried to use this equipment but could not create a suitable input format because of a specific uncorrected peculiarity of not being able to read lines of greater than six inches without repeated rejects. we were aware of this from our experience which is why we kept our line short using the ro to terminate reading of the line at the last character position. also our input was double spaced, not single spaced as you seem to infer in your comments. with this particular device we also found that the format recognition line was easily lost, necessitating greater time spent in re-running the job. therefore, even though this was a great commission of sin on our part according to mr. silberstein, i then must plead guilty to using expedient methods to turn a bad situation into an acceptable one. i might also point out that this solution had been employed at various times by some past users we contacted. in fact, i have later found out that occasionally such a technique has been resmted to in one of our other local user installations on a much newer machine. i do not wish to imply that our conversion achieved maximum through-put but that in any case it was a cost effective way to proceed. with a small file conversion such as this one which is to be done on a one-shot basis, it seemed foolish to me to spend much time optimizing, but rather to find a way that worked as our difficulties were encountered. if this had to be a continuing job we would have had to get a better maintained scanner and invested more time and money into the project. i take the view that we wish to couple modest human costs with modest projects and reserve for greater projects of a continuing nature more optimized procedures. i agree that file cleansing is undoubtedly the most costly operation but i cannot say by just what amount since my responsibilities did not include such work. this technical communications 65 was later performed by our technical services department. our general point in writing about this project was to convey our broad experiences using this technique on a subject authority system as we had not seen such use reported in the literature previously. i would hope your comments and mine here serve to illustrate that one's systems problems must be solved in light of the conditions and not always according to what we term the best theory or practice. to this end i hope others will profit from both of om comments. audrey n. grosch university of minnesota libraries balancing community and local needs: releasing, maintaining, and rearchitecting the institutional repository article balancing community and local needs releasing, maintaining, and rearchitecting the institutional repository daniel coughlin information technology and libraries | march 2022 https://doi.org/10.6017/ital.v41i1.14073 daniel coughlin (dmc186@psu.edu) is head libraries strategic technologies, penn state university. © 2022. abstract this paper examines the decision points over the course of ten years of development of an institutional repository. specifically, the focus is on the impact and influence from the open-source community, the needs of the local institution, the role that team dynamics plays, and the chosen platform. frequently, the discussion revolves around the technology stack and its limitations and capabilities. inherently, any technology will have several features and limitations, and these are important in determining a solution that will work for your institution. however, the people running the system and developing the software, and their enthusiasm to continue work within the existing software environment in order to provide features for your campus and the larger open-source community, will play a bigger role than the technical platform. these lenses are analyzed through three points in time: the initial roll out of our institutional repository, our long-term running and maintenance, and eventual new development and why we made the decisions we made at each of those points in time. the institutional repository (ir) a university institutional repository (ir) provides long-term access to the scholarship and research outputs of an institution.1 the outputs can be in the form of scholarly publications, data sets to support publications or other research, electronic theses and dissertations, and other digital assets that have value to the university to preserve and to the research community an d beyond to disseminate. there is additional value in keeping these otherwise scattered resources collected in a single repository to showcase the scholarly accomplishments of an institution.2 there is value to the university to collect and disseminate the scholarly outputs of the university to understand the strengths of the university and promote that research to outside audiences, attract new faculty, and provide opportunities for new faculty where fields may be emergent or void of an institutional presence. furthermore, there is value to the research community to be able to find peer research without having to pay publisher access fees. reducing the burden on faculty to meet various policy demands from a federal, publisher, and institutional perspective provides another motivation for irs. federal policies can require making anonymized research data and scholarship publicly available because it is publicly funded through tax dollars; publishers can make authors provide access to the data that supports the research that is being published.3 in the united states, a growing number of academic institutions, from 2005 to 2021, have adopted an open-access policy that requires researchers to provide a copy of any published scholarly article in a publicly accessible repository. the institutional repository is a way for a university to meet this increasing demand from research organizations and funding institutions for their researchers.4 as the size of a campus grows in disciplines, it inherently grows in complexity and a diversity of digital needs and use cases from its researchers. for example, high-resolution images or mailto:dmc186@psu.edu information technology and libraries march 2022 balancing community and local needs | coughlin 2 atmospheric data are likely to create a higher demand in storage needs than a discipline that relies largely on text. performance-based research may require multimedia resources and streaming capabilities while other large files can be shared in a more asynchronous manner. the diversity of needs contributes to the complexity of finding a solution for an institutional repository that meets all, or many, of the needs on a campus from a file storage, discovery, and access perspective. this paper broadly addresses penn state university’s development of its ir at three distinct points in time: (1) choosing a platform for our ir and its initial release; (2) maintaining an ir; and finally, (3) our current solution nearly 10 years later. at each point in time, we analyze our decision process through four lenses. these lenses provided a thorough examination for us to decide on how to proceed; they are community needs and potential tension that exists with local needs, our team dynamics, and finally the platform we built our software on and the infrastructure required to maintain it. we discuss why we made the decisions we made through these four lenses, the benefits and drawbacks, and what we have learned along the way. penn state is the state of pennsylvania’s land grant university in the united states. the university has 24 campuses physically located in the commonwealth of pennsylvania, the world campus which is online, two law schools, and a medical school. in the fall of 2021, penn state had 73,476 enrolled undergraduate students and 13,873 graduate students, with research expenditures totaling over $850 million for the last four years.5 penn state is a large, public research institution with a diverse set of needs. this is significant because when the university is considering developing a large system such as an institutional repository, we need to meet the needs of a broad set of disciplines and domains. we are fortunate enough to have software developer and system administration resources that smaller institutions may not have. this provides a bit of context into our considerations for an institutional repository. selecting a repository in january 2012, penn state university libraries and penn state’s central information technology department collaborated on developing an institutional repository for the university’s growing data management needs. the university libraries was interested in becoming more involved in open-source software community development efforts. at that point, many universities that we had spoken with had an existing ir solution in place, and we had a lot of freedom to choose a platform without the burden of data migration. we considered investigating (1) off-the-shelf, turnkey solutions such as dspace, (2) a prototype we had just built called curation architecture prototype services (caps) using a microservices approach, or (3) building on top of an existing platform. ultimately, we decided to build on top of an existing platform, samvera (named hydra at the time).6 we did not want a turnkey solution, because we felt that we had distinct needs that would require a level of customization that these solutions would not be able to offer. based on discussions with others, we decided to develop something of our own. we wanted to leverage the experience of others in the repository development domain. the microservices approach at the time was more of a conceptual approach towards development than an existing software solution. the ability to build on an existing platform was a happy middle ground for us and we evaluated this decision through several lenses that led us to our selection at that time. community involvement we did not want to develop a solution in a vacuum and thought a group with a (relatively) common set of problems would be helpful to problem solve. the samvera community was a small but growing community working towards repository solutions like what we were trying to information technology and libraries march 2022 balancing community and local needs | coughlin 3 achieve. members of the community were both managerial and technical. this was valuable to us for understanding the strategic direction for the community and the ability to collaborate and problem solve on technical implementations. some of the key partners for our early work were university of hull (uk), stanford university, university of virginia, and notre dame. there was communication throughout the year over community email, chat platforms, and phone calls; however, the quarterly partner meetings were the most valuable time for collaboration. these quarterly meetings were a couple days in length, typically at a partner institution’s campus (physically) attended by managers and software/systems developers. this provided the ability to work together on specific problems, showcase our work, and get to know each other more closely at lunch and after-hours meetups. working within the community would also get our team increased exposure and help with recruiting future colleagues. working in the open-source software community has been seen to benefit both candidates and employers in future job recruitment.7 we were excited by the promise of working with and contributing toward a larger community. our team had apprehension about building this alone, and we were happy to be working with the support of a community and within their set of processes. local needs early on in our requirements for the repository we created a moscow chart that provided our “must have,” “should have,” “could have,” and “won’t have” features.8 the platform we were choosing was going to provide us with a significant set of these features for our repository with very little work on our end. these features were built in and included search, discovery, and basic file edit functionality. essentially, we were going to quickly meet the needs of our stakeholders by using this software. this was important for a couple of reasons. first, providing features to our stakeholders quickly gave them ample time to provide feedback so that we could make necessary customizations for their specific needs. a less quantitative benefit was gaining the trust of colleagues at the start of a new project and new initiative. rather than continually suggesting “that feature will be done next week,” we were able to deliver results quickly and get feedback. for example, our repository integrated with our campus authentication system, restricting access. we were able to deliver these features and get feedback on both the functionality as well as terminology to improve the usability. in particular, the way our developers described permissions was initially too confusing for our users and we were able to make necessary adjustments prior to a production release of the ir. team dynamics we believed it was a significant professional development opportunity for many people on the team to work with a larger community and learn from and with those in the open-source community. the team working on the ir consisted of three full-time, or near full-time, developers (one joining after we started the project), and a systems administrator. this project was our first large project that included a project manager invested in agile project management methodologies and with a systems administrator in place at the beginning of the project. platform and infrastructure stability there was a desire to get to a common solution to easily set up other repositories for various needs within the libraries and we hoped there would be an ability to plug and play various components or features. the three common components of this system were fedora commons to store both metadata and our digital assets; solr as an index for fast search; and blacklight as a web interface that sits on top of solr. one of the primary components, active-fedora, would sync content between the fedora and solr persistence layers. our hope was that with this model, we information technology and libraries march 2022 balancing community and local needs | coughlin 4 would be able to write code that could be used in other repositories, and we could use the code that other institutions had written for our repository needs to build other applications more quickly. the samvera community was initially called hydra because of the relationship with the mythical creature that has several heads (see figure 1). we were considering the potential of running a core storage infrastructure and discovery infrastructure, while developing several heads for our various applications. we knew this was a lofty expectation, but also thought that it was a good design principle for us to advance. additionally, the pilot that we developed on microservices (caps) seemed to have a relatively large storage service and we could not determine how to get away from that. although this was a bit of a shift in our philosophy, it was less of a shift based on our practical experience. figure 1. aspirational intentions of running many applications on one access and discovery system. initial release the initial release of our ir, scholarsphere, was for research data, scholarly articles, and presentations. we considered the repository file agnostic and left the definitions of scholarly materials up to the depositor. the self-deposit process made very few assumptions to limit the barriers to deposit—there were few mandated fields for deposit in scholarsphere. the initial rollout of scholarsphere had met the “must have” and many of the “should have” needs that we had defined initially in our development requirements. the list of “must haves” included upload files via the web, create and assign metadata to the uploaded files, set three access levels to the files, search for files, display files, etc. the list of “should haves” were faceted browse, faceted search results, share files with a group, etc. the benefit of working on a community-developed platform provided some of these features for us (search, faceted browse), and gave us the flexibility to customize where necessary. for example, we had our own data model of metadata to assign to files based on our users’ needs. we were able to update the existing metadata that was information technology and libraries march 2022 balancing community and local needs | coughlin 5 provided out of the box, to accommodate that. this was a tremendous win for us to leverage community-provided solutions and local needs. additionally, the platform provided a search index with solr. this enabled our infrastructure to have a common solution with community support on configuration questions. using the blacklight ui on top of solr created another opportunity for us to customize where desired and ease of development efforts. community: following the initial release, we worked with other members of the community to pull out some of the core functionality and place it in a separate ruby library. this library (sufia) could then be leveraged as a default set of repository features for other developers. the release of a new ir, and this library, provided us with a lot of positive exposure at various community events. local needs: locally, we used this library to develop a repository for our digital archives. it previously took two to three developers nearly nine months to develop scholarsphere; however, we used the sufia module to roll out a separate repository in six months with a single developer. this was another successful production rollout and a successful use of a product created by and for the community. team dynamics: we had a successful release and were getting support for new developers to hire. we continued to move more of our projects toward an agile approach and permanently embed systems administrators into our development projects. infrastructure: we had not released a new system for archives on the exact same system that scholarsphere was developed on, but we were happy that our projects were relatively homogeneous technology stacks and provided a familiarity to run. maintaining the ir over the next several years we released three major updates to scholarsphere: 1. migrating the data object store to a major version 2. overhauling the user interface 3. migrating our data model to the portland common data model (pcdm) simultaneously, the sufia library that we developed had also grown in usage by other institutions and contributions from other developers. we were excited to have additional contributors, and with that came an understandable sense of competing priorities within our community’s development roadmap. we were building scholarsphere features and functionality to meet the needs of our local institution and managing the tension between community direction and local needs. again, we look at these lenses as evaluating the period during maintenance, upgrades, and feature adds. community involvement two of the major releases mentioned above were largely community driven. in one case— migrating the data object store—we were one of the initial repositories within our open-source community to migrate our data storage system. we anticipated that doing this work early would prevent us from having to rewrite any code that relied on the data storage layer. ultimately, this may have been a bit early for us, because we never were able to create the momentum for others in the community to make this same migration. this created a bit of a divergence, but at this layer in our technology it did not prevent us from continuing to work closely with the community. information technology and libraries march 2022 balancing community and local needs | coughlin 6 we were able to add locally developed features for managing files and uploads, community components that allowed for controlled vocabularies, and cloud provider uploads.9 in all, from 2012 to 2019 we were an active member of the community: we provided technical contributions, we were being asked to present at community events, and our developers were frequently asked to help at several workshops. the community provided many opportunities for professional development and code from the community provided new features to our users. we felt this work was successful. we had three major releases. one was something that our local users were able to experience directly. two of our upgrades were largely on the back end and, while there is no argument on their importance, it can be a challenge to illustrate the significance of largely opaque technology upgrades to users. concurrently, we were coming up against other challenges that were proving difficult to solve in a sustainable and scalable way. large file size (larger than 1 gb) for uploads and downloads remained an issue that researchers seemed to be encountering more frequently. our mechanisms for getting around some of these obstacles led us to looking at an api for administrators and other applications to integrate. for example, if the web browser upload was not working, perhaps we could physically get the file from a user and upload it to the system ourselves. if we could do that, maybe we could use an api to do this upload, but we did not have an api. when developing new features, we would question if it should be code to contribute back to the community or only for our (penn state) needs. frequently, the devil is in the details and , while several institutions were interested in a feature based on a conversation, implementation could be much more detailed and it was difficult to find common ground. this complexity could lead to longer timelines and more difficult planning for local development features. team dynamics over this time period we advanced our team by adding several highly skilled developers (some of whom have now moved on to other positions and remain highly respected within the community), and enriched the collective skill set of the group. the team was enriched by this experience overall. the balance between community involvement and local needs became a frequent conversation point for our team. we spent a lot of effort on initiatives that had not solved some of the bigger problems our users were experiencing locally; our community disengagement was likely a combination of common reasons, for example, our lack of time to make meaningful contributions.10 in the spring of 2019, the development team that worked on scholarsphere shrunk from three developers down to one. we had a strong number of developers within the samvera community to collaborate with; however, we had difficulty bringing on new members at the time because the complexity within the scholarsphere system created a high learning curve that was not necessarily transferable to other technology stacks. at the end of the summer in 2019 we were given 25 gb of video files to upload in scholarsphere and make accessible. the parameters of the request were outside of what we could support from our web interface, and we had no api to allow a product owner to develop against and work with the researcher to meet this request. after approximately one month of working with the data and our system, we successfully ingested the files into scholarsphere. at the end of this month, we information technology and libraries march 2022 balancing community and local needs | coughlin 7 decided that we needed to more urgently evaluate our path forward because we could not have our lone developer spending this amount of time on single-user requests. platform and infrastructure stability each of the major versions released between 2012 and 2019 had several patches and feature releases to enhance the system, the interface, and/or our processes for change management within the software system. for example, we went from a typed script containing a series of commands to chef (a language used to automate software deployment) for deployment management; we upgraded infrastructure core components (fedora, solr, travis, redhat, etc.); and we added infrastructure to keep up with the system demands. in terms of adding infrastructure, we both enhanced the virtual capabilities (cpu and ram) of our systems and had tasks offloaded to other systems. we did not want the systems our users interfaced with to be responsible for all the heavy lifting. these tasks included characterization, indexing metadata for search, creating thumbnails, etc. (see figure 2). figure 2. systems and services with basic workflow process for uploading a file to scholarsphere, including the background jobs that ran on file upload. adding additional components improved the user experience but made our infrastructure d ifficult to manage. we were continually trying to push our systems to reflect the best practices of the twelve-factor app.11 however, over time, we had certain “infrastructure smells.” the infrastructure smells were essentially anti-patterns of these best practices or symptoms of a bigger problem.12 these anti-patterns included: • storage coupled closely to application • lack of flexibility to scale storage to integrate • inability to spin up a scholarsphere instance web 1 repo isilon jobs mysql services • apache • rails • passenger • clamav services • maria db services • tomcat • fedora • jetty • solr • redis services • rails • resque • fits services • nfs jobs on upload • characterization • thumbnail creation • text extraction (solr) • derivatives information technology and libraries march 2022 balancing community and local needs | coughlin 8 • taking days to set up a dev environment • lack of flexibility to decouple small tasks that may require increased resources (create derivatives) evaluating next steps although we were coming up against some struggles and continued maintenance with scholarsphere it was a successful software project that had several things we liked (and likely took for granted). it was important for us to recognize what features and characteristics of scholarsphere were a part of this list. scholarsphere‘s data model was flexible enough to support several current use cases and future needs and was developed with a significant amount of community input. there were other development teams within our organization that were also developing new applications in ruby, so the language continued to be relevant within ou r larger group as was ruby on rails, blacklight, and solr. some of the libraries developed with these frameworks were providing us with struggles and we knew that tools and infrastructure could be barriers to newcomers onboarding and orientation.13 however, the languages themselves were still flexible enough for us to continue our work. we had three permission levels to access the full text of an uploaded file: (1) public, (2) penn state only, and (3) private, and we didn’t want to develop anything more complex than that around access permissions. fedora provided us with versioning capability of our objects and we thought that this was something not only to continue but potentially enhance. we also had strong support from the samvera community for scholarsphere. many people had worked on the code that helped provide functionality and we could collaborate within that community when problems arose. at that point we largely decided to continue to develop needed features for scholarsphere while the community pushed forward. in part we were hoping that our divergent paths would converge within a year (give or take). the month following the relatively manual process of ingesting the 25 gb of video files into scholarsphere was spent making important updates to the system and fixing any low-hanging fruit. in october 2019 we decided to start from scratch and spend about two months developing a new solution and to evaluate our path forward after that. current solution we turned to the same four established lenses when evaluating our needs in 2019. however, it is worth noting that organizationally we were in a much different position than when we started in 2012. the software development and infrastructure team that managed the service was organizationally moved from central it to the libraries where the service and product owner resides. being in the same building and having the same priorities improved communications. also, people within the teams had changed, and our leadership had changed, which changed how we approached some of our decisions. we had more experience in technical skills, specifically in repository development; we were more refined in our implementation of agile methodologies; and having run a service for years, we had a better sense of our users’ needs. community involvement the community saw a tremendously successful period of growth during this time in adoption of software, exposure for funded grants, and number of partners. there was renewed excitement about multiple solutions including turnkey repository solutions, hosted solutions, the merging of two highly regarded software libraries for performance, and improvement in developer friendliness. the latter improvement stripped some of the design patterns that developers struggled with to something more familiar and made it easier to onboard new developers. information technology and libraries march 2022 balancing community and local needs | coughlin 9 local needs the pressure to meet our local needs and competing priorities for the community-based software became a sticking point for us. we needed to have a more scalable backend and we were not su re when our needs and the priorities of the community would merge. we had also been behind on several dependencies and the lift to get back up to date, before being able to add anything new, was considerable. this situation led us to create a prototype for evaluation. our initial goal was to see how difficult it would be to build a system to meet the needs of uploading the video files that scholarsphere currently could not handle. we had confidence we could develop features, but this area was a consistent challenge and we considered it a primary hurdle for us to jump. team dynamics our development team consisted of a single developer. however, we had an infrastructure developer who was able to help with systems configuration, automation, and containerization. our developer thoroughly understood scholarsphere and the underlying codebase and architecture and had the resources to hire a consultant to help with our efforts. we had considerable work performed by a local software development company on other repositories (electronic theses & dissertation system, a digital cultural heritage repository, and our researcher metadata database). we valued this partnership and wanted to continue to utilize them as our staff numbers were down. we needed to be able to more quickly onboard others than we previously had in the past. if we were able to have three relatively new members of the team contributing to this progress, then we would also potentially have chosen a technology stack that was comfortable for others outside our development team to make a more immediate impact. platform and infrastructure stability as with many systems that are actively developed for years, our current system had several dependencies that had organically grown over time to become burdensome to put together in order to set up a development environment. additionally, a local development environment was not an exact replica of the production environment because networked storage was implemented on production and our development systems had a local storage. we also took this opportunity to test out amazon s3 storage options as our production storage system. we chose this alternative to see if we had increased reliability in our storage and to see how well we could manage data in s3 and get a production service using this to provide an example of the annual operating cost by using the cloud vendor. we were able to simplify our rollout a bit, and modernize the technologies used to run our systems (i.e., docker containers, kubernetes cluster) (see figure 3). development we had three general goals: (1) to improve stability/scalability for local needs; (2) to improve our ability to get an environment up for developers more simply; and (3) to be able to onboard new developers more quickly. shortly after our prototype test proved we could meet local needs in scalability, we were able to test out our second goal, getting a scholarsphere environment set up easily. the process of setting up a development environment went from days to hours. we had reached two of our three goals with these tests and believed our development team (that was two to three new developers) contributing to our first two goals was proof that we could onboard new developers quickly (our third goal). after several months of development in early 2020 we had accomplished moving several of the obstacles that had been in our way in recent years but were nowhere near feature parody with scholarsphere. information technology and libraries march 2022 balancing community and local needs | coughlin 10 figure 3. current infrastructure for scholarsphere, released in november of 2021. we had a rich feature set to transfer from the existing scholarsphere and did not want to simultaneously run two systems until we achieved some level of feature parody. we wanted to get to a minimal viable product (mvp) for our new prototype, migrate data, release our new version, and retire our existing system. our product owner had been working directly with scholarsphere users and was able to help us determine priorities for the features we needed in order to have an mvp. the following were some of those features: • an api, at the very least an internal one for o our migration script o other home-developed applications o internal library employees • versioning and the ability to view versions • updated status (pending published) • updated user interface • urls that were harvestable • maintaining our data model for continued support of concepts such as collections • enhanced support for dois information technology and libraries march 2022 balancing community and local needs | coughlin 11 we also identified some features that had been developed over the years to either simplify or eliminate. the profiles within scholarsphere were not heavily used and over the years the university had more mature systems for this type of purpose. similarly, finding a featured researcher for the home page seemed to create more work than it was worth, and our social media integrations were not going to be a priority. we also thought a user’s dashboard—the default page after logging in—could be greatly simplified based on the most prominent actions our researchers wanted to perform. conclusion after a little over a year of development, in november 2020, we released our new version of scholarsphere. we used our own internal api, as planned, for data migration from our existing fedora commons storage system into the new one in amazon s3. over the past seven months we have done nine feature releases, including collections, and an enhanced api to support penn state’s open access initiative. we learned some lessons along the way within all of these lenses. we have also more than doubled the physical storage size of our repository since releasing in november 2020. over the summer, we were able to meet a faculty member’s request to upload 30 to 40 videos of 300 to 400 gb, a request we never would have been able to meet in our prior solution. community & local needs working with the samvera community has provided countless opportunities for our entire team. we were able to sharpen our technical skills, were given opportunities to lead workshops, organized community development sprints, and collaborated on a plan for a community roadmap (to name a few). our entire team benefitted in several ways by the involvement in the community: our software knowledge is higher, our problem-solving skills are more creative, and our outside professional opportunities expanded. ultimately, our paths diverged in a way that made it difficult to justify the time and resources required for merging back. there are several benefits to community-based software: more eyes looking at potential security issues in code, more voices to let you know when a dependency of your code has beco me vulnerable, shared software ideas for developing issues, and shared solutions for common problems. the cost of all these benefits comes with increased complexity in organizing a solution (you need to take multiple institutions into account), workflows for development (your local workflow may not be the same as the community approved workflow), competing priorities within the community, and competing priorities with the community and local roadmap. open source communities are largely online, these groups typically have a more shared, informal leadership structure and that lack of formal leadership can make it difficult to find solutions to these complexities.14 team dynamics, and platform and infrastructure stability rewriting a system can be a daunting task, and several prominent developers would argue against it.15 reasons we believe we were successful are that (1) we did not change our data model, (2) although we changed our architecture, we did not change our coding conventions or our agile development process, and (3) the benefits of our changes were multidimensional. we were meeting users’ needs with our development work and our infrastructure was enhancing our capabilities and making the work of our developers easier and less frustrating. our deployment process has improved to the point that we can perform a release easily and without downtime. information technology and libraries march 2022 balancing community and local needs | coughlin 12 our technology is no longer based on samvera, and is now, largely, a more generic ruby on rails application. we migrated from using fedora as both a metadata and object store (retrieving objects on our central isilon system through fedora) to using postgres as a metadata store and amazon’s s3 storage service for our files. we migrated our background jobs processing services from rescue to sidekiq. we continue to use blacklight discovery and search interface, with solr as our search platform. many of these technical decisions were made because of the change in dynamics of our team, and perhaps the single biggest change was around experience and the confidence that comes with that. selecting a platform and infrastructure to support that platform is daunting. it is particularly difficult when you have so many questions in front of you about how the system will be used, the demand it may be under, the need to scale, how to deploy new features and update dependencies, etc. our decisions in 2019 were made with much more experience and understanding of what was required of our system as well as what desired by our users. this gave us the confidence to branch off slightly from the joined technical path and recognize all the value (beyond technical solutions) to remain members of the community albeit in a modified capacity. acknowledgements many people put in tremendous time, effort, skill, thought, and enthusiasm

deliver their service in the digital environment. libraries are transforming from being places for reading to extensions of the classroom and learning spaces. due to the globalized digital environment and intense competition, libraries are trying to improve their service quality through various evaluations. as reference service is crucial to users, this study explores user satisfaction towards the reference service through whatsapp, a social media instant messenger, at a major university in hong kong and discusses the correlation between the satisfaction rating and three variables. suggestions and recommendations are raised for future improvements. the study also sheds light on the usage of reference services through instant messaging in other academic libraries. introduction due to the advancement of new technologies and mobile devices, library resources and services are more accessible.1 apart from independent searching strategies, the interactions between librarians and users have become an effective method to solve user problems, referred to as reference services.2 according to the reference and user services association (rusa), reference services include creating, managing, and assessing reference transactions and activities. 3 with the increasing user needs, reference services have become an essential part of library services and commonplace in academic libraries.4 further, technology development requires reference librarians to possess updated skills, willingness, and interest to deal with user inquiries.5 recently, due to the covid-19 pandemic, users have increasingly utilized virtual reference services to help them obtain information required for their academic studies instead of face-to-face modes.6 some libraries have employed different virtual tools, for example, instant messaging services, to provide reference services to their users. one of the most popular global instant messaging services is whatsapp.7 referring to the digital 2022—hong kong report, the most-used social media platform among internet users aged 16 to 64 in hong kong was whatsapp (84.3%), followed by facebook (83.7%), instagram (65.6%), wechat (55.2%), and facebook messenger (50.4%).8 the popularity of whatsapp in hong kong accordingly increases whatsapp reference service usage in academic libraries. the qualitative study by tsang and chiu has identified whatsapp as one of the most commonly-used and relatively preferred reference services of an academic library in hong kong.9 mailto:kguo@connect.hku.hk mailto:applelamwork@gmail.com mailto:dicksonchiu@ieee.org mailto:ho.kevin.ge@u.tsukuba.ac.jp information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 2 many studies have investigated reference service quality with measurements such as satisfaction rating, perceived gaps in reference services ability to meet user expectations, and other information-seeking behaviors. however, few studies focus on instant messaging reference services compared to traditional services, except for a notable recent qualitative study by tsang and chiu.10 therefore, this research aims to quantitatively evaluate user satisfaction with whatsapp’s application in reference service of a major university’s library in hong kong through three dimensions: affect of service (as), information control (ic), and library as place (lp), which are detailed in the research purpose section. the results can help librarians better understand the effectiveness of applying whatsapp and other instant messaging to improve reference service quality. by expanding technology-based services, libraries can become more competitive in the digital era and provide better user experiences in the future. thus, this study deals with the following four research questions (rqs): rq1. what is the users’ awareness level of the library’s reference services? rq2. how do users evaluate the whatsapp application in the library? rq3. what are the relationships between user satisfaction and the three service dimensions as, ic, and lp? rq4. how can academic libraries increase user satisfaction with whatsapp reference services? literature review in the late 1800s, library leaders started to pay attention to the importance of reference services. 11 since then, reference services have also caught the public’s attention and were introduced into public libraries. reference services can assist readers in solving problems through various interactions between users and staff.12 currently, the library is not merely a repository of collections, and librarians can provide more help, particularly fulfilling users’ various information needs rather than just offering directions or physical locations of books.13 nowadays, librarians strive to solve various user problems and inquiries with their professional skills and information literacy.14 at first, in-person and telephone were the most common ways for reference services. however, with the increasing number of remote users and ubiquitous internet connectivity, face-to-face reference and asynchronous emails can no longer satisfy users’ needs.15 thus, libraries increasingly explore collaborative software and mobile applications such as instant messaging, online chatting, video sessions, and other methods to serve users, referred to collectively as virtual reference.16 virtual reference occurs electronically in real time, where users may interact with librarians through smartphones, computers, or other devices without physical presence.17 as libraries began to use the internet, several case studies investigated instant messaging reference services in academic libraries.18 at the same time, librarians and researchers began to investigate reference service quality with designated measurements. various indicators can help measure user satisfaction levels, such as accuracy, communication skills, user satisfaction, instruction, and user’s willingness to return.19 although these indicators were originally developed for physical reference services, most principles and methods can still be applied to virtual reference services, as instant messaging has become one of the most frequently used information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 3 channels.20 some studies have confirmed the effectiveness of instant messaging for reference services for more traditional means, such as phone and email.21 as one of the most popular social media chatting software platforms, whatsapp has become a powerful tool for connecting librarians and users. a primary difference from traditional phonebased reference services is that whatsapp can share texts, images, documents, and videos (and their links) at a low cost.22 whatsapp can run as a mobile application on smartphones or as a web page on desktop browsers named whatsapp web. whatsapp web users are required to use their mobile phone to scan the qr (quick response) code on the computer browser (https://web.whatsapp.com/) for authentication before use. as the functionality of whatsapp web is similar to whatsapp, users can easily adapt to whatsapp web on desktop computers. as of march 2020, the number of active whatsapp users has globally increased to approximately 2 billion and is still growing steadily.23 whatsapp, by april 2021, had become the most popular messaging application based on the number of monthly active users, compared with other popular messaging applications.24 studies also indicate that students may use whatsapp for two to three hours daily.25 although the essential chat functions of whatsapp are similar to other instant messaging services such as facebook messenger and wechat, whatsapp and wechat have been more popular for hongkongers and mainland chinese, respectively.26 surprisingly, howard et al. studied students’ habits of using social media platforms at purdue university in the us and revealed that respondents rarely use whatsapp in their daily lives, indicating that residents in different regions may have different social media platform preferences.27 recently, odu and omini have demonstrated a significant relationship between using whatsapp and library service satisfaction from the student’s perspective.28 some studies also stressed that many students welcome whatsapp as an effective reference service platform.29 however, friday et al. pointed out that some librarians might not be trained and equipped with proper and up -todate skills in using social media tools to provide library services effectively and efficiently.30 further, aina, babalola, and oduwole argued that hurdles such as instructional policies, lack of time, and heavy workloads might cause difficulties in using these tools to provide library services.31 as for evaluation, mohd azmi, noorhidawati, and yanti idaya aspura applied rusa’s guidelines for the behavioral performance of reference and information service providers to evaluate the perceived importance versus actual practices of whatsapp reference service from librarians’ perspectives.32 they suggested that although librarians expressed their awareness of the importance of rusa guidelines, they would not fully comply with the guidelines because of time and other constraints. yet, few studies deal with the satisfaction with whatsapp reference services of academic libraries from user perspectives. research purpose regarding whatsapp and library services, a few studies focused on finding the relationship between whatsapp and service usage, user attitudes toward whatsapp applications, and the difficulties of using whatsapp, particularly for reference services.33 though mohd azmi, noorhidawati, and yanti idaya aspura evaluated librarians’ behavioral performance in providing whatsapp reference service, it was from librarians’ perspectives instead of users.34 https://web.whatsapp.com/ information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 4 thus, we studied user satisfaction with the whatsapp reference service offered by academic libraries by adapting tsui’s instrument to develop the survey framework.35 tsui employed three key indicators, i.e., affect of service (as), information control (ic), and library as place (lp), in libqual+, an online library assessment tool developed by the association of research libraries (arl).36 as measures “empathy, responsiveness, assurance, and reliability of library employees,”37 like librarian-user interactions concerning the librarians’ knowledge in inquiry responses and the level of reference service provided.38 ic measures “how users want to interact with the modern library and include scope, timeliness and convenience, ease of navigation, modern equipment, and self-reliance,”39 such as library resource availability and accessibility from user perspectives. 40 lp measures “the usefulness of space, the symbolic value of the library, and the library as a refuge for work or study,”41 such as the availability of adequate facilities and an appropriate physical environment from user perspectives.42 the application of these indicators will be further discussed in the methodology section. methodology this study chose a major academic library in hong kong with a long track record of technological advancement. a reference desk is situated near the library’s main entrance for traditional services. the library’s web page shows a clear ask a librarian column with diversified methods for reference services, including email, telephone, whatsapp, and other electronic devices to access the reference services. notably, the whatsapp reference service is operated the same as other channels, available monday to friday from 9 am to 5 pm (except on public holidays). the library promises an inquiry response in no more than four hours. the mission and vision of such reference services are to • help locate information resources; • assist in searching strategies and research; • deal with queries about the use of facilities and services; and • equip users with information literacy. the library has developed a whatsapp business account with a mobile phone in the whatsapp business application and uses the whatsapp web function to handle user inquiries on desktop computers. one to two library assistants support the whatsapp reference service on shift seamlessly from 9 am to 5 pm, including the lunch break, and a professional librarian reviews whatsapp inquiry records weekly. this study used a survey administered through google form, both online and offline, to collect user perceptions about the library’s whatsapp reference service. online methods for collecting survey responses included email, facebook, wechat, and whatsapp, and offline methods included site delivery at the library entrance and sticking the survey qr code on public notice boards. no incentives were provided for the voluntary data collection. the data collected comprised mainly undergraduate and postgraduate students to represent a general user view of the whatsapp reference service. microsoft excel and ibm spss statistics were used to analyze the data, including bivariate correlation for investigating the relationships between whatsapp satisfaction and the three variables based on tsui’s study, as, ic, and lp.43 among these indicators, as focuses on whether whatsapp is easy to use and supportive; ic evaluates the response speed, accuracy, and accessibility of the whatsapp reference service; and lp measures the staff attitude and whether whatsapp helps encourage librarian-user information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 5 communication. the survey also includes demographic information, reference services usage, and user satisfaction with the whatsapp reference service. participants were asked to evaluate the quality of whatsapp reference service from these three dimensions through five-point likert scales in the satisfaction rating part. finally, the survey asked for the overall satisfaction and other useful comments about the reference service. data analysis demographic information as the main analysis of this study is regression analysis, a check on the minimum number of participants needed for analysis was performed. as explained later in this paper, the regression involved six predictors of satisfaction. using medium effect size and 0.8 as the statistical power, the minimum sample size should be 97 using an online a-priori sample size calculator for multiple regression (https://www.danielsoper.com/statcalc/calculator.aspx?id=1). the data collection yielded 131 completed responses, with 66% of master’s students and the rest undergraduates. respondents had diversified academic backgrounds, including education (26.0%), science (14.5%), business and economics (13.0%), engineering (12.2%), liberal arts (10.7%), social science (9.9%), architecture (9.2%), and legal studies (4.6%). for the time spent on instant messaging such as whatsapp and wechat, 39% spent more than three to five hours every day, while one-fifth of them would spend one to two hours. 22% of respondents spend five hours or above, and only a small portion of them (19%) would spend less than an hour. in summary, most respondents would spend at least one hour on instant messaging daily. usage of reference service table 1 summarizes respondents’ usage of reference services with a five-point likert scale (1 = never; 5 = always). as shown, walk-in and email are the most common methods to use the reference service, while whatsapp is the least frequent. when it comes to the purposes of using reference services (see table 2), databases and e-resources and identifying information sources are the two most common purposes for respondents, followed by service and facility and research assistance. table 1. usage frequency of

https://www.danielsoper.com/statcalc/calculator.aspx?id=1 information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 6 when asked about their preferred way to use reference services, more than half of the respondents said they would use email (67.9%), followed by walk-in (59.5%), whatsapp (23.7%), and phone (12.2%). as the traditional method, most respondents considered walk-in, in-person reference the most effective reference method because users could receive instant help from librarians, especially for urgent and complex problems. however, results indicated that despite a gap in users seeking reference services help by instant messaging and email, this gap is smaller than that for face-to-face and telephone.44 the user ratings for reference services through different methods were compared using anova. our result shows a significant result, f(3, 520) = 30.52, p < 0.01. walk-in (m = 4.18, sd = 0.71) is the most satisfying method. post-hoc tests showed the rating of email (m = 3.78, sd = 0.60) and phone (m = 3.73, sd = 0.83) statistically indifferent and lower than walk-in, while both were considered better than whatsapp (m = 3.27, sd = 0.90). apart from these ratings, respondents were also asked to leave a few comments and suggestions for the reference service. notably, most respondents showed a positive attitude to the whatsapp reference service while suggesting some improvements. for example, one respondent requested “longer office hours for whatsapp.” at the time of this research, the whatsapp reference service hours were monday to friday from 9 am to 5 pm, while in-person reference service reference hours were monday to friday, 8:30 am to 7 pm, and saturdays from 8:30 am to 7 pm. therefore, the library should extend the whatsapp service hours to provide more flexible service time, aligning with the findings of tsang and chiu.45 further, a respondent suggested that librarians should “respond to email more efficiently.” for this issue, whatsapp could serve to expand user access to reference services instead of emails. users’ satisfaction with whatsapp reference service prior research reported that as, ic, and lp influenced user satisfaction. this study adapted the instrument developed in tsui’s prior research (see appendix) to collect data to investigate these relationships.46 as the cronbach’s alpha values for all three constructs are higher than 0.7, it is valid to use the average value of these items for our data analysis.47 table 3 shows the analysis of whether respondents’ academic level would affect as, ic, lp, and overall user satisfaction with whatsapp using anova. results indicated that academic level affected as but not the other factors and satisfaction. further, multiple regression results indicated that ic and lp affected whatsapp satisfaction. table 4 tabulates our findings. table 3. anova results overall undergraduate (n = 45)

master’s student = 1) in our regression model (i.e., interaction effect), the following effects are notable. first, as does not affect user satisfaction with using whatsapp for reference services for undergraduates but positively affects master’s respondents. second, ic positively impacts satisfaction for both undergraduate and master’s respondents, of which the difference between these two respondent groups is statistically insignificant. lastly, even though lp also positively impacts satisfaction for both groups, the effect is higher for undergraduates than for master ’s respondents. the different learning needs of the groups may explain such differences, as shown in table 5.48 table 4. regression analysis main effect interaction effect independent variables coefficient t-value

correlation with whatsapp satisfaction for master’s students, while the as part had the lowest satisfaction with undergraduate students. this reflected that respondents who are undergraduates could not receive adequate supportive help from librarians through whatsapp, aligning with the findings of tsang and chiu.49 a possible reason is that the number of whatsapp reference librarians with specialist subject knowledge was information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 8 small. yet, one general reference whatsapp number on the library website is insufficient compared to other methods, as the library website shows seven telephone numbers of branch libraries to serve different patrons. through different numbers, users could easily find the required experts accordingly. the whatsapp reference service had only a single number probably because users mostly ask basic and general questions. such a process would cost professionals too much time and energy to deal with.50 to further enhance the service, it is necessary to reform the operational policies and add a few more whatsapp accounts, for instance, creating a whatsapp business account for each branch library (a total of six branch libraries) or for each school serving users in different disciplines to connect to corresponding subject librarians via specialized whatsapp accounts.51 this approach can separate users from the general inquiry number dealing with quick and straightforward information inquiries from those requiring specific domain inquiries.52 further, the general inquiry whatsapp service should be extended to cater to various students’ needs by possibly improving to provide 24-hour service.53 to remedy human resources requirements, student helpers, interns, and volunteers can serve on shifts on saturdays, sundays, and even public holidays.54 more users may seek troubleshooting services during the holidays, especially long holidays, and recently, under the covid-19 pandemic and its associated isolation requirements.55 more staff training due to the whatsapp reference service features, the skills required for online and face-to-face conversations are different, e.g., it is difficult to convey emotions like facial expressions and body language online.56 further, due to the limited interactions between librarians and users and the lack of visual and audio cues through the whatsapp reference service, librarians can hardly identify user needs in a short time.57 therefore, librarians may need further professional training for such scenarios, particularly in answering questions quickly and precisely in real-time chat, because users tend to be more impatient during a chat engagement.58 in addition, unlike face-toface inquiry, some complex issues often cannot be adequately explained through whatsapp. therefore, librarians should make appropriate referrals if some problems cannot be solved through whatsapp. reference services through video-based platforms such as zoom can also help.59 regular training could offer librarians updated information on using the tool and refresh the skills used in responding to the whatsapp reference service among various staff members, i.e., librarians, library assistants, student helpers, volunteers, and interns. if the library staff does not acquire well-developed skills and competencies in texting, comprehension, and communication specialized in instant messaging services, they cannot efficiently and effectively understand the inquiries and search, locate, explain, and convey the appropriate information resources to users on the asynchronous whatsapp reference service in a shorter response time.60 establishment of whatsapp reference service guidelines whether the whatsapp reference service increases the capability to deal with user problems, it still relies on consistently favorable reference behaviors.61 mohd azmi, noorhidawati, and yanti idaya aspura pointed out that users need timely responses and friendly online contacts from librarians, though librarians might not completely follow the rusa guidelines due to human resources constraints.62 therefore, libraries should establish easy-to-follow, concise, and information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 9 whatsapp-tailored guidelines for appropriately conducting whatsapp reference services, especially because such skills differ from face-to-face services, as discussed above.63 the studied library has developed a simple series of internal work procedures for using whatsapp web, including how to open and close whatsapp web and how on-duty staff should handle inquiries. to enhance and standardize the whatsapp reference service, the library should develop guidelines by offering some polite, brief, and interactive text templates for answering inquiries, such as “i am (name) (job title). what may i help you with, dear user?”, as well as answers to frequently asked questions. progress reporting messages should be sent to users to acknowledge their searching status.64 the relationship between librarians and users can thus be enhanced by creating a consistent, friendly, and warm atmosphere, using informal conversation and emojis, and incorporating whatsapp’s features to engage users and establish continued service use.65 further, such guidelines can save time and energy in training new staff and provide the basis for the future development of artificial intelligence aids such as chatbots.66 promotion for the whatsapp service most respondents conveyed a positive attitude, considering whatsapp a convenient way to access the reference service, which is in line with the studies by ansari and tripathi and sudharani and nagaraju.67 however, it is still not the most frequently used and preferred method in the library. one reason is that users still need help with physical materials and ask for the answers face-toface. 68 however, this is not the only reason, as many studies showed that library promotional efforts are often weak.69 in addition to the traditional promotional materials such as leaflets and contact cards with whatsapp numbers, the library can also broaden the promotion through massive emails and social media such as facebook, instagram, linkedin, twitter, and signal.70 in the information era, social media is an effective and efficient channel for reaching the target audience and disseminating information in an accessible way. 71 the library should reform the webpage of the whatsapp reference service to further attract users. for instance, displaying some sample whatsapp chat screenshots of librarian-user interactions on the library’s website can increase the attractiveness of the service as images can graphically represent the application’s ease of use for library reference help.72 conclusion the study has investigated user satisfaction with the whatsapp reference service in a major academic library in hong kong and explored the correlations between whatsapp satisfaction with three quality dimensions as, ic, and lp. the survey revealed various opinions toward using reference services and preference methods, including inconsistencies between users’ frequently used methods and preferred methods. moreover, by analyzing the correlation between whatsapp satisfaction and the three variables, results showed that users emphasized the whatsapp reference service. the results have led to some practical suggestions for improvement: subdividing the whatsapp reference service with subject specialists, providing more staff training, establishing staff guidelines and policies, and increasing whatsapp service promotion. limitations and future research there are still some limitations to the study. firstly, the survey only collected limited complete responses, which may not represent all users’ views. additionally, the perceptions of both library information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 10 staff and users should be considered. secondly, the research evaluation design with three dimensions can be extended to measure other quality and effects. thirdly, as whatsapp is just one application among various emerging instant-messaging tools, further studies should cover other instant messaging platforms for similar and different purposes. for instance, as the studied university comprises a significant student population from mainland china, wechat could be investigated for its possibility and effectiveness as a whatsapp alternative for providing reference services and promotion to chinese students.73 information technology and libraries september 2022 perceived quality of whatsapp reference service | guo, lam, chiu, and ho 11 appendix: key survey items item mean sd. affect of

limitations and future research appendix: key survey items endnotes static vs. dynamic tutorials: applying usability principles to evaluate online point-of-need instruction benjamin turner, caroline fuchs, and anthony todman information technology and libraries | december 2015 30 abstract this study had a two-fold purpose. one is to discover through the implementation of usability testing which mode of tutorial was more effective: screencasts containing audio/video directions (dynamic) or text-and-image tutorials (static). the other is to determine if online point-of-need tutorials were effective in helping undergraduate students use library resources. to this end, the authors conducted two rounds of usability tests consisting of three groups each, in which participants were asked to complete a database-searching task after viewing a text-and-image tutorial, audio/video tutorial, or no tutorial. the authors found that web usability testing was a useful tutorial-testing tool while discovering that participants learned most effectively from text-and-image tutorials because both rounds of participants completed tasks more accurately and more quickly than those who received audio/video instruction or no instruction. introduction the provision of library instruction online has become increasingly important, given that more than one third of higher education students now take at least some of their courses online and that the number of students enrolling in online courses continues to increase more rapidly than the number of students in higher education as a whole.1 academic library websites reflect the growth of online education. by 1998, online versions of journals had become ubiquitous.2 in contrast, electronic books have been slower to be adopted in academic libraries, but there has been a steady and significant growth of their use in recent years. between 2010 and 2011, for example, the average number of electronic books available at academic libraries in the united states increased by 93 percent.3 benjamin turner (turnerb@stjohns.edu) is associate professor and instructional librarian, caroline fuchs (fuchsc@stjohns.edu) is associate professor and outreach librarian, and anthony todman (todmana@stjohns.edu) is associate professor and reference and government documents librarian, st. johns university libraries, new york, new york. mailto:turnerb@stjohns.edu mailto:fuchsc@stjohns.edu mailto:todmana@stjohns.edu static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 31 with the increasing availability of library content online, many users bypass the “brick and mortar” library and go directly to its website.4 remote access to library collections has advantages in terms of convenience, which further underscores the importance of making library websites as intuitive as possible while offering quality instruction at point-of-need. a recent survey of 264 academic library websites found that 64 percent offered some form of online tutorials.5 the relative effectiveness of different types of tutorials in providing online, point-of-need library instruction is therefore an important consideration for library professionals. this study had a two-fold purpose. one is to discover through the implementation of usability testing which mode of tutorial was more effective: screencasts containing visual and audio directions (dynamic) or text-and-image tutorials (static). the other is to determine if online point-of-need tutorials were effective in helping undergraduate students use library resources. for the purpose of this study, researchers were less interested in the long-term effects of these tutorials on student research but rather focused on point-of-need instruction for database use. st. john’s university st. john’s university is a private, coeducational roman catholic university, founded in 1870 by the vincentian community. the university has three residential campuses within new york city and an academic center in oakdale, new york, as well as international campuses in rome, italy, and paris, france. the university comprises six schools and colleges: st. john’s college of liberal arts and sciences; the school of education; the peter j. tobin college of business; college of pharmacy and health sciences; college of professional studies; and the school of law. there is a strong focus on online learning. special academic programs include accelerated three-year bachelor’s degrees, five-year bachelor’s/master’s degrees in the graduate schools, a six-year bachelor’s/jd from the school of law, and a six-year pharmd program. in fall 2013, total student enrollment was 20,729, with 15,773 registered undergraduates and 1,364 international students. during the 2012–13 academic year, 97 percent of undergraduate students received financial aid in the form of scholarships, loans, grants, and college work/study initiatives. the student body was 56 percent female and 44 percent male, representing 47 states and 116 countries. the diversity of student population is noted by the fact that 47 percent identified themselves as black, hispanic, asian, native hawaiian/pacific islander, american indian, alaska native, or multiracial. st. john’s university has a library presence at four campuses: queens, staten island, manhattan, and rome, italy. in addition to traditional or in-person interaction, both information technology and libraries | december 2015 32 online and distance learning are integral parts of the library-tutorial and instruction environment. undergraduate students receive a laptop computer at no cost, and the entire campus is wireless accessible. full-time faculty members receive laptop computers as well. the university libraries has 24/7 access to electronic resources, both on and off campus. the libraries’ portal is located at http://www.stjohns.edu/libraries. an online catalog can be found at http://stjohns.waldo.kohalibrary.com. wireless computing and printing are available at the four campus library sites as well as in other areas across campus. library reference and research assistance services are delivered in-person or electronically. library reserve services are accessible in either print or electronic formats. interlibrary loan has both domestic and international borrowing and lending via the illiad software platform. when the main queens campus library is not open for service, a 24/7 quiet study area is available for current students within the library space. library instructional services take place in formal classes that are requested by faculty, as well as library faculty-initiated workshops held in either the libraries’ computerized classrooms or at other on-campus locations. there is no mandated information literacy session. during june 2012–may 2013, 333 instruction classes were offered to 4,435 students. literature review the library literature on online library tutorials might be divided into subcategories: early development of online instructional tutorials, library website usability testing, evaluation of online information-literacy instruction tutorials, best practices for the creation of library tutorials, and the best mediums for the creation of library tutorials. early development of online instruction tutorials the need to evaluate and assess the usefulness of online instructional tutorials is not new. although not explicitly related to today’s environment, tobin and kesselman’s work contains an early history detailing the design of internet-based information pages and their use in the library information environment.6 they also included the early guidelines of the association of college and research libraries (acrl), the international federation of library associations (ifla), and the american library association (ala). a study by dewald conducted around the same time evaluated twenty library tutorials according to the current best practices in library instruction, and concluded “online tutorials cannot completely substitute for http://www.stjohns.edu/libraries http://stjohns.waldo.kohalibrary.com/ static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 33 the human connection in learning”7 and should be designed specifically to support students’ academic work. further, it was noted that tutorials should teach concepts, rather than mechanics, and incorporate active learning where possible.8 in a separate article, dewald argued that the web made possible new, creative ways of teaching library skills, through features such as linked tables of contents, and the provision of immediate feedback through cgi scripts. users also were able to open secondary windows to practice the skills they learned as they moved through tutorials. she further concluded that effective instructional content should not be text heavy, but rather include images and interactive features.9 another early study of online tutorials discussed the development of a self-paced web tutorial at seneca college in toronto, called “library research success,” which was designed to teach subject-specific and general research skills to first-year business majors. the creation of the tutorial was first requested by seneca college’s school of business management, which collaborated with seneca college library, the school’s centre for new technology, and centre for professional development in completing the project. the tutorial was a success, with overwhelmingly positive feedback from students and faculty members.10 despite such successful examples, a common concern expressed in early studies was that online tutorials would not be as effective as face-to-face instruction. one article compared and evaluated library skills instruction methods for first-year students at deakin university.11 another tracked the difference between cai (computer assisted instruction) without a personal librarian interaction and a more traditional library instruction incorporated into an english classroom setting, and which concluded that while useful, cai was not a good substitute for face-to-face instruction.12 library website usability testing as concern grew at the onset of the twenty-first century for the need to evaluate online library tutorials, articles on library website usability testing began to appear more frequently. in one study, the authors noted that they would not have identified problems with their website had they not done usability testing: “testers’ observations and the comments of the students participating in the test were invaluable in revealing where and why the site failed and helped evaluators to identify and prioritize the gross usability problems to be addressed.”13 librarians aiming to examine their patrons’ ability to independently navigate their library’s webpage to fulfill key research needs, conducted similar studies. at western michigan university (wmu), librarians investigated how researchers navigated the wmu library website in order to find three things: the title of a magazine article on affirmative action, the title of a journal article on endangered species, and a recent information technology and libraries | december 2015 34 newspaper about the senate race in new york state. they successfully used the data gathered to identify problems with their website and to establish goals and priorities in clarifying language and navigation on their site.14 more recently, researchers conducted a usability study with the aim of showing how librarians could build websites to better compete with nonlibrary search sites such as google, which would allow greater personalization by the individual user and more seamless integration into learning management systems.15 other researchers have studied the readability of content on academic library websites. in one such study, lim used a combination of readability formulas and focus groups to evaluate twenty-one academic library websites that serve significant numbers of academically underprepared students and/or students who spoke english as a second language. they concluded that the majority of information literacy content on library pages had poor readability, and that the lack of welldesigned and well-written information literacy content could undermine its effectiveness in serving users.16 kruger, ray, and knight employed a usability study to evaluate student knowledge of their library’s web resources. the study produced mixed results, with most students able to navigate to the library’s website and the opac, but large numbers unable to perform basic research tasks such as finding a journal article. the authors noted that such information would allow them to modify library instruction accordingly.17 another study focused on the use of language as it relates to awareness of relevant databases. at bowling green university library, staff members attempted to learn more about how users find and select databases through the library website’s electronic resources management system (erm). because of their study, the authors recommended that librarians should focus on promoting brand awareness of relevant databases among students in their subject disciplines by providing better database descriptions on the library webpages and by collaborating with subject faculty members.18 evaluation of online information-literacy instruction tutorials librarians at wayne state university conducted an assessment of their revamped information literacy tutorial, known as “re:search.”19 they distributed a multiplechoice knowledge questionnaire to seventy-two students participating in their 2010 wayne state federal trio student support service summer residential program, which was based on donald kirkpatrick’s evaluating training programs: the four levels.20 they concluded that their study highlighted some flaws in their tutorials, including navigational problems. as a result, they would consider partnering with wsu faculty in the future to develop better modules. one curious comment by the authors in their introduction warrants further discussion about assumptions made static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 35 by librarians regarding student research skills: “the internet has bolstered student confidence levels in their research abilities, increasing the demand for point-of-need instruction. students are accustomed to online learning, not only because of the shift in higher education to online coursework, but also because they have been leaning online through youtube, social networking, and other websites.”21 at purdue university, librarians evaluated the success of their seven-module online tutorial through the distribution of a post-test survey. these researchers found that the feedback received was essential for planning future versions of online instruction at their institution.22 a report from zayed university (united arab emirates) outlined an evaluation of infoasis, the university’s online information literacy tutorial, testing 4,000 female students with limited library proficiency and remedial english aptitudes.23 best practices for the creation of library tutorials other researchers developed guidelines and best practices for future planning and implementation. bowles-terry, hensley, and hinchliffe at the university of illinois conducted interviews to investigate the usability, findability, and instruction effectiveness of online video tutorials. although shorter than three minutes, students found the tutorials to be too lengthy, and would have preferred the option to skip ahead to pertinent sections. other participants found the tutorials too slow, while some preferred to read rather than watch and listen. on the basis of their study, the authors recommended a set of best practices for creating library video tutorials, including pace, length, content, look and feel, video versus text, findability, and interest in using video tutorials.24 at regis university library, librarians created online interactive animated tutorials and incorporated google analytics for use statistics and tutorial assessment, from which they developed a list of tips and suggestions for tutorial development. these included suggestions regarding the technical aspects such as screen resolution and accessibility. of some significance is that the data from the analytics suggest that the tutorials are being used both within and without the university. most useful here is the “best practices for creating and managing animated tutorials” found in the article’s appendix.25 best mediums for the creation of library tutorials other authors have explored the need to accommodate different learning styles in library tutorials rather than relying too heavily on text to convey information.26 at the university of leeds in the united kingdom, an information literacy tutorial was planned and created to support online distance learners in the geography postgraduate program. using an articulate presenter, the authors created a tutorial that information technology and libraries | december 2015 36 covered the same material that would be taught in a face-to-face session, and which incorporated visual, auditory, and textual elements. these researchers concluded that the online tutorial is supplemental and did not alleviate the need for face-toface instruction.27 to reach different types of learners, many librarians have begun to use adobe flash (formerly macromedia flash) to create multimodal online information literacy tutorials. authors who use flash note that learning how to use the software correctly represents a significant investment in time and effort.28 another study, conducted via a suny albany web design class, focused on the effect/outcome of teaching with web-based tutorials in addition to or instead of face-to-face interaction. the authors of this study pointed out that self-paced instruction, lab time, office, hours, and email exchange were all factors that are affecting web-based multimedia (wbmm) flash that were incorporated into instruction.29 rather than focusing purely on the content of online library instruction tutorials, some studies considered and evaluated the various tutorial-creating software tools. blevins and elton conducted a case study at the william e. laupus health sciences library at east caroline university, which set out “to determine the best practices for creating and delivering online database instruction tutorials for optimal information accessibility.”30 they produced “identical” tutorials using microsoft’s powerpoint, sonic foundry’s mediasite, and techsmith’s camtasia software. they chose to include powerpoint because “previous research has shown that online students prefer powerpoint presentations to video lectures.”31 their testing results indicated that participants found specific tutorial features to be most effective: video (33.3 percent), mouse movements (57.1 percent), instructor presence (28.6 percent), audio instruction only (28.6 percent), and interaction (28.6 percent). they concluded that camtasia tutorials provided optimal results for short sessions such as database instruction and that for instruction where video and audio of instructor + screen shots, mediasite was more appropriate. however, they also determined that powerpoint tutorials were an acceptable solution if cost were an important factor.32 in a separate study at florida atlantic university, researchers described the process of designing and creating library tutorials using the screencasting software camtasia. in addition to the creation of the tutorials themselves, the authors described how the project entailed the development of policies and guidelines for the creation of library tutorials, as well as training for of librarians in using camtasia software.33 this study provides another good example of the time investment involved in the creation of multimedia tutorials. static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 37 while the professional literature thus shows that flash-based tutorial software is popular among librarians, and the desire to accommodate students with different learning styles is a laudable goal, at least one study suggests that the time and money involved in the creation of multimedia tutorials could be better spent in other ways. a university of illinois urbana-champaign study found that students from different learning styles performed better after using tutorials made with a combination of text and screenshots than from tutorials created with camtasia software.34 method usability testing for the evaluation of tutorials in dynamic audio/video tutorials compared with text and image tutorials, the researchers employed usability testing, which is “watching people use something that you have created, with the intention of making it easier to use, or proving that it is easy to use.”35 usability testing requires relatively small numbers of participants to provide meaningful results, and it does not require the selection from a representative sample population.36 participants group number of participants control group 1 5 text-and-image group 1 5 dynamic audio/video group 1 5 group 1 total 15 control group 2 5 text-and-image group 2 5 dynamic audio video group 2 5 group 2 total 15 total participants 30 table 1. breakdown of participants thirty freshmen at st. john’s university participated in this study. while usabilitytesting experts do not place a great deal of importance on recruiting participants from a specific target audience, the researchers wanted to choose users who were less likely to have had significant experience with university library database searching, since prior knowledge could make it harder to determine the effectiveness of the tutorials. they therefore chose freshmen as the participants in the study. they did not seek any other variables such as age, gender, information technology and libraries | december 2015 38 ethnicity/culture, or any other demographic information. participants were recruited through the st. john’s central portal, which is the main channel of internal communication at st. john’s university, and through which mass emails can be sent to a targeted population of students. the email to students provided a registration link to a google form, which asked students to provide their name, year of study, time availability preference, and contact information. freshmen were selected from the response list. as an incentive for participation, the student participants became eligible for a kindle fire tablet for each of the two rounds of the study. prior to beginning the study, the authors consulted st. john’s university’s office of institutional research, which oversees all research at the university, and provides approval for the study of human subjects. since this study focused on tutorials rather than the participants themselves, the authors were granted a waiver for the study. tests usability testing typically involves having participants complete a task or tasks in front of an observer. for this study, the authors designed two tasks that required participants to find articles in academic search premier ebsco database (asp ebsco). the first task, given to all participants in the first round of tests, was relatively simple, and consisted of three components: finding an article about climate change published in the journal lancet and downloading a copy of the citation for that article in mla format from the database. participants who attempted the first task were labeled “group 1” (see appendix i). the second task was given to all participants in the second round of tests and was more complex, comprising five components. participants were asked to find an article about the deepwater horizon spill from a peer-reviewed journal published after 2011 that included color photographs. as with the first task, these participants were also required to download a copy of the citation for the article in mla format from the database. participants who attempted the second task were labeled “group 2” (see appendix ii). group 1 and group 2 were divided into three subgroups each. the first subgroup was the control group and received no instruction. the second subgroup was given access to the dynamic audio/visual tutorial (see appendix iii). the third subgroup was given access to the static text-and-image tutorial instruction (see appendixes iv and v). each subgroup consisted of five unique participants. each participant was scheduled for a specific fifteen-minute time slot. tests were conducted in a small meeting room in the library, with one participant at a time working with the facilitator. as the participants entered the meeting room, the static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 39 facilitator greeted them and confirmed their identities. participants were provided with an information sheet (see appendix vi), which told participants that the session would be recorded, that the researchers were concerned with testing the libraryinstruction tutorials, not the participants themselves, and that the tests were confidential and anonymous. participants were also told that they could end the test at any time for any reason. additionally, the facilitator read aloud the points-ofinformation sheet. participants were invited to ask questions or voice concerns. for both rounds of tests, participants had use of a laptop computer with a browser window open to the asp ebsco home page. for those who received instruction, a second browser window was open to either the dynamic or the static tutorial. for members of the control group, no tutorial was available. those who received instruction were allowed to return to the tutorial at any point they wished. using adobe connect software, the testing activities, tutorials, participants’ attempt(s) at task(s), participants’ computer screen, and any conversation between the participants and the facilitators were simultaneously recorded and broadcast to a separate room, where the two other researchers observed, listened and took notes. the participants were asked to verbally describe the steps they were taking, as per the “think aloud” protocol that is essential to usability testing. recorded sessions were then available for later review by the research team. on completing the task, participants who received either the text-and-image or dynamic audio/video tutorial were asked to complete a short questionnaire giving feedback on the instruction received (see appendix vii). participants who received no instruction were not asked to provide feedback. tutorials the researchers created four tutorials for this study. two were flash-based dynamic audio/video tutorials created using techsmith’s jing software. the static text-and-image tutorials were created using microsoft word, which was then converted into a pdf document. the dynamic and static tutorials mirrored each other in terms of content, and were designed with the specific goal of helping participants complete the tasks successfully, though in both cases there was some variation between the tutorials and the tasks. the tutorials received by group 1, for instance, showed participants how to find articles about the occupy wall street movement, limiting the search to “published in the new york times,” and how to download the citation in mla format. the tutorials for group 2 showed participants how to find articles about climate change that included color photographs, limiting the search to peer-reviewed journals that were published after 2011. discussion information technology and libraries | december 2015 40 the results of the usability study revealed two things: participants benefited from library instruction, through which they evidently acquired new skills; and participants benefited more from static text-and-image tutorials than from the dynamic audio/video tutorials. in both rounds of tests, the participants who received the text-and-image tutorials performed the tasks more effectively than did members of the control group or those who viewed the dynamic tutorials. group 1 for the first round of tests, members of the control group spent longer on the task and made more mistakes than those who received either the dynamic or the static tutorial (see table 2). for example, one participant in the control group was unable to download the mla citation, and another in the control group ventured outside the asp ebsco database platform to find the correct citation format. when members of the control group did succeed, they did so without a clear search strategy, evidenced by their use of natural language instead of boolean connectors. (asp ebsco uses boolean connectors by default, and natural language is usually ineffective.) another participant reached several dead-ends in the search before finally succeeding. while most of the control group participants were at least partially successful in completing the task, it is reasonable to suspect that they would have given up in frustration in a non-test situation, and would have benefited from point-of-need instruction. control 1 control 2 control 3 control 4 control 5 relevant article y y y y y lancet y y y y y mla citation y n y y y time on task (minutes) 8:28 2:49 6:30 2:41 1:42 average time on task: 4:26 mins. table 2. task completion success and time, control group 1 the participants who received the static text-and-image tutorial performed the best, completing the task with the highest speed and with the greatest accuracy (see table 3). all five of the participants in this group managed to find appropriate articles and to download the citation in mla format, though several had difficulty with the final task. all were able to navigate to the “cite” feature effectively, but all participants chose to click on the “mla” link rather than simply copy the citation. clearer directions in the tutorial might alleviate this problem. static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 41 t&i 1 t&i 2 t&i 3 t&i 4 t&i 5 relevant article y y y y y lancet y y y y y mla citation y n y y y time on task (minutes) 2:01 3:00 2:21 2:40 3:15 average time on task: 2:39 mins. table 3. task completion success and time, text and image tutorial, group 1 participants who received the dynamic video tutorial were more successful than those in the control group, but spent significantly longer on task than did those who received the static tutorial (see table 4). interestingly, two of the participants searched for “climate change” as the “subject term” in asp ebsco, even though the tutorial did not instruct them to do so. (su subject term is one of the options in the drop-down menu in asp ebsco, which otherwise searches citation and abstract by default.) while “climate change” is a commonly accepted scientific term, and the searches produced relevant search results, it is not generally advisable to begin a search with controlled vocabulary terms. t&i 1 t&i 2 t&i 3 t&i 4 t&i 5 relevant article y y y y y lancet y y

pronounced in the second round of tests, which involved a more complex task (see figure 3). as in the first round of tests, the participants in the control group had the lowest number of satisfactory task completions, and spent the greatest amount of time on task. although most of the participants in control group 2 had at least partial success in completing the task, most did so through trial and error, and showed a general lack of understanding of database terminology and functions. one participant, for example, attempted to use “peer-review” and “color photographs” as search terms. another attempted to search for “deepwater horizon” as a journal title. only two of the participants completed all components of the task successfully. two others partially completed the task – one found a suitable article with color photographs, but published in the nation, which is not peer-reviewed. one user failed to complete any part of the task and gave up in frustration (see table 5). control 1

success in round 2. three of the five participants who received the static tutorial completed all components of the task successfully. errors committed by the two others were related to publication

suggests that the text-and image-tutorials are suitable for quick reference and allow users to access needed information at a glance. video 1 video 2 video 3 video 4 video 5 relevant article y y y y y

was unable to locate the citation feature, while another failed to limit to peer-reviewed articles. four of the participants limited the publication date from 2011 to the present instead of 2012 to the present. all participants correctly used the publication limiter. although given the option, none chose to return to the dynamic tutorial after starting the task. this might be because of the length of the tutorial (more than three minutes) and the difficulty in navigating to specific sections. information technology and libraries | december 2015 44 as noted above, participants in all groups tended to make errors related to publication date, which may have stemmed from the wording of the task itself rather than misunderstanding the functionality of the database. the task required participants to find articles published after 2011, but many found articles published from 2011 onward. clearer wording of the task probably would have alleviated this problem. figure 3. average time

todman | doi: 10.6017/ital.v34i4.5831 45 tutorial feedback after completing the task, participants were asked to provide anonymous, written feedback on the instruction they received. (members of the control groups were not asked to provide feedback because the purpose of the study was to compare different types of library tutorials.) participants were asked ten questions, eight of which were on a likert scale and two of which were openended. although the feedback for both the static and dynamic tutorials was generally positive, the text-and-image tutorials also received higher combined scores than the audio/visual tutorials on the likert scale questions (see figures 5 and 6). participants’ written feedback on the text-and-image tutorials was generally more positive than for the video tutorials. commenting on the text and image tutorial, one participant remarked that it was a “great resource” while another said that it was “very easy to use. will become really helpful when put into full effect.” another observed that the tutorial “was pretty precise.” not all the comments on the text and image tutorials were positive, however. more than one participant noted that the images used in the tutorials were blurry. one even suggested that “more animations to the text would make it much more open to people with different learning styles.” the feedback on the video tutorials was generally positive, with comments such as “very straightforward,” “helpful,” “easy to follow,” and “i would use this for school assignments.” however, a common complaint about the dynamic tutorials was that the audio was not very clear. (this may be because the quality of the microphone used for the recordings.) other participants seemed to criticize the layout of the database itself, saying that bigger size of words would have made it easier to follow. another complained that the dynamic tutorial was too simple, and that it should cover more advanced and in-depth topics. figure 5. tutorial feedback likert score averages group 1

suggests that library users benefit from online instruction library instruction at pointof-need, and that text-and-image tutorials are more effective than dynamic audio/visual tutorials for its provision. librarians should not assume that instructional tutorials must use flash or other video technology, especially given the learning curve, time, and financial commitments involved in creating video tutorial software. although the researchers in this study used the free software jing, learning to use it effectively was still a significant investment in time. more importantly, it is evident that the participants learned more and were more satisfied with text-and-image tutorials, which were more easily navigated than dynamic audio/video tutorials and which allowed users to more easily review tutorial content than did dynamic audio/video tutorials. this study corroborates the findings of mestre, who found that text-and-image tutorials were more effective than audio/video tutorials in teaching library skills.37 it also lends credence to the work of bowles-terry, hincliffe, and hutchinson, who found that users preferred tutorials that allowed them to read quickly and navigate to pertinent sections rather than watch and listen.38 as lim suggests, it is important to create instructional material that is clearly written.39 it further suggests that regardless of the technology used, librarians should focus on creating content that is relevant and helpful to our user population. again, it is worth noting that the control group, without the aid of point-of-need instructional materials, achieved some success in completing the tasks. it is possible that the members of the control group gained important knowledge simply by being told about asp ebsco and that there was enough implied information in the tasks themselves to provide basic information about the content and functionalities of the database. this suggests that databases like asp ebsco are intuitive enough that people can learn how to use them independently. the higher number of serious errors, and the greater length of time members of the control group spent on tasks, 0 1 2 3 4 5 text tutorial group #2 video tutorial group #2 static vs. dynamic tutorials | turner, fuchs, and todman | doi: 10.6017/ital.v34i4.5831 47 however, shows that efforts to raise student awareness of databases and library resources should be coupled with point-of-need instruction. although the usability tests generally went smoothly, researchers did encounter occasional difficulties with audio between the testing room and the observation room when it became difficult to hear what the participant was saying as he or she was completing the task. fortunately, the researchers kept recordings of each test, which allowed them to review those where the audio quality was less than optimal. to save time and run the tests more efficiently, however, the researchers recommend purchasing a high-quality microphone like those used for teleconferences. furthermore, this study shows the broader value of usability testing of library instructional material. although participants who received the text-and-image tutorials performed better than either of the other two groups, the tests helped researchers identify two problems with the tutorials: users found the images blurry and often misinterpreted how to download citations in mla format. such information gleaned from the user’s perspective would be valuable in creating future library online point-of-need instructional tutorials. references 1. i. elaine allen

multiyear plan to execute its charge. this plan is structured around digitization preparation (phase one), development of procedures and workflows (phase two), and promotion and communication to the project’s targeted audiences (phase three). the plan contains step-by-step actions to conduct an environmental scan, inventory the theses and dissertations collections, purchase equipment, craft policies, establish procedures and workflows, and develop digital preservation and communication strategies, allowing the task force to achieve effective planning, workflow automation, progress tracking, and procedures documentation. the innovative and creative approaches undertaken by the theses and dissertations digitization task force demonstrated collective intelligence resulting in scaled access and dissemination of the university’s research and scholarship that helps to enhance the university’s impact and reputation. introduction to answer the call of implementing university of houston (uh) libraries strategic plan to position the libraries as a campus leader in research and transform library space to reflect evolving modes of learning and scholarship, the uh libraries

activities. a study by bennett and flanagan revealed the positive impact and benefits of online dissemination of theses and dissertations, including enhanced discoverability by google’s strong indexing capabilities, significant increase in the usage of the works, and an overall enhancement of the reputation of an institution.1 encouraged by the positive outcomes and supported by funding from the john p. mcgovern foundation to initiate this project, the theses and dissertations digitization (tdd) task force developed a phased project plan and utilized creative, automated processes and methods to execute it. this article articulates the tdd project planning and the innovative work undertaken by the task force to achieve efficiency in making our print theses and dissertations readily available to new readerships around the world. literature review over the past several decades, research libraries have been building programs around digitization and open access repository infrastructures, largely aimed at expanding their digital collections and engaging communities with newly available research materials. for some, part of their programming has included projects that digitize their institution’s legacy print collections of theses and dissertations. the review below explores literature on the mass digitization process , including institutional case studies, guidance documents, legal and policy papers, and local documentation developed as libraries have planned and implemented these projects. any library tackling a retrospective thesis and dissertation project needs a framework for determining the copyright status of these works en masse. perhaps it is no coincidence, then, that copyright concerns are the most heavily documented aspect of the process. clement and levine provide the definitive work to date on copyright and the publication status of theses and dissertations written in the united states before 1978. their study asserts that “p re-1978 american dissertations were considered published for copyright purposes by virtue of their deposit in a university library or their dissemination by a microfilm distributor.”2 they go on to write that, “for copyright purposes, these were acts of publication with the same legal effect as dissemination through presses, publishers, and societies.”3 they suggest that libraries should investigate the copyright status for theses and dissertations authored between 1909 and 1978 (typically found on the title page and verso); if there is no copyright notice, then the thesis or dissertation is likely in the public domain and eligible for digitization and public release without permission. moreover, even those works that have a printed copyright notice might have fallen out of copyright if they were not renewed after 28 years for the same length of time.4 broad guidance and best practice for copyright status and other matters of process around theses and dissertations is provided in guidance documents for lifecycle management of etds, which acknowledges that legal services may be required for some retrospective thesis and dissertation digitization projects, especially “before scanning without the permission of former students .”5 the authors assert that information professionals should investigate any “appropriate access options” with institutional legal expertise before engaging in a retrospective digitization project and articulate the two most commonly encountered copyright scenarios: “[either] former student authors may not allow the reproduction and open dissemination of their work, or unauthorized copyrighted material was used in the original theses and dissertations.”6 strategies that might be employed to determine copyright status include “consulting with legal counsel at one’s institution to see where it stands on this issue; negotiating with commercial entities that make such content information technology and libraries september 2022 navigating uncharted waters | 3 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith available at a price so that institutions can have some control over it for the purpose of broader access; and working with groups such as alumni associations, colleges, departments, and graduate schools to establish contact with thesis and dissertation authors for securing their permission to digitize, and render available online, their past scholarship.”7 on the question of public access to newly digitized works, the guidance documents detail the implications of the “transition from print to electronic,” which “has led to increased scrutiny over who will be allowed to access the electronic versions and how widely they will be disseminated.”8 when there is any legal doubt, there are many reasons for libraries to exercise caution and restrict access to electronic theses and dissertations; that said, “research available on the web immediately upon submission of the final, approved thesis can prove advantageous to the newlydegreed student, the institution, and other researchers.”9 again, consulting legal officers and the original authors, if possible, remains the consensus approach to establishing a strategy for access to digitized theses and dissertations. the guidance documents also touch on the thorny issue of digitizing theses and dissertations that contain third-party content. they summarize the history and routine application of the fair use doctrine in both the creation and dissemination of scholarly works but provide little firm guidance on the matter.10 indeed, after reviewing the entire body of literature on retrospective thesis and dissertation projects, this remains a practical challenge that any library undertaking a mass digitization project must consider and the associated risks must be accounted for. in recent years, several case studies have documented institutions’ efforts to digitize and make more widely available legacy theses and dissertations. of the institutions that the tdd task force reviewed for the environmental scan, none of their case studies attempts an exhaustive documentation of end-to-end workflows and processes developed to execute the task; most focus on particularly difficult questions inherent to the process. martyniak provides a rationale for the university of florida’s (uf) retrospective scanning project and details their process for contacting authors before works were scanned.11 the workflow outlines several points of contact with authors to obtain signed distribution agreements, as well as uf’s approach to automate this process as much as possible. notably, the distribution agreement form and correspondence templates are provided as appendices to the article.12 as part of this retrospective digitization project, uf also released a scanning policy that articulates their approach to determining the copyright status of works and their resultant practice. 13 this policy document is an excellent example of an institution’s implementation of clement and levine’s research described above. likewise, mundle describes the methods used by simon fraser university (sfu) to establish its approach to the issues of copyright status and access, ultimately resulting in a public thesis access policy and procedures for contacting authors whenever possible to offer them the ability to opt their work out of the project.14 unlike the uf, sfu began scanning before any explicit permission had been obtained from authors. sfu also shares their use of scripts to automate the ingest of metadata from original marc records into their dspace repository.15 piorun and palmer, meanwhile, focus on an analysis of the time and cost associated with digitizing 300 doctoral dissertations for a newly implemented institutional repository at the university of information technology and libraries september 2022 navigating uncharted waters | 4 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith massachusetts chan medical school.16 piorun and palmer detail the library’s process for obtaining cost comparisons from external vendors as well as estimated costs, including labor, associated with undertaking the task in house.17 issues of workflow, policy development, and permissions are also addressed with an emphasis on developing accurate and streamlined methods of processing works; however, piorun and palmer conclude, “regardless of the amount of planning and thought that goes into a project, there is always the possibility that each record or file will need to be reworked.”18 shreeves and teper discuss theses and dissertations’ complicated status as grey literature and the university of illinois urbana-champaign (uiuc) library’s digitization project, which they describe as “less of a collection management or preservation issue and more as an effort to tackle broader scholarly communication and outreach issues.”19 after consulting with university legal counsel, digitized works were ingested to the uiuc institutional repository as a restricted (campus -only access) collection. as authors provide consent, access to their work is broadened to the public. worley demonstrates that, according to an analysis of circulation numbers, works that are accessible electronically are used dramatically more than print copies, serving as rationale for undertaking digitization of student works.20 they provide significant detail around virginia polytechnic institute and state university’s process to establish file specifications for its digitization process, and image quality/resolution and file format selection are discussed in some detail, with helpful visual examples.21 these case studies are particularly valuable in that they provide evidence and cautionary tales around how local contexts have made a difference in copyright and workflow issues. this case study contributes to the existing body of literature by attempting to provide an exhau stive, end-toend description of the retrospective digitization process—from copyright evaluation, to physical handling, to digitizing with an eye to access controls and digital preservation concerns. furthermore, our approach to digitization at scale incorporates automation at several points throughout the workflow, representing a production improvement to the decade-old case studies we reviewed. project planning and execution digitizing a large corpus of print theses and dissertations is a complex process touching areas of equipment, copyright policy, workflows for different sections of the process, progress tracking, preservation, and communication. to handle such a multifaceted project, the tdd task force designed a plan that divided the project activities into three phases (see table 1). phase one is dedicated to tasks of preparation such as the environmental scan, copyright permission investigation, digitization equipment purchasing, and print theses and dissertation inventory. phase two includes activities such as digitization and metadata workflow development, documentation, project tracking, ingestion, and preservation of digitized files. phase three is mainly for promotion and communication to our researchers on the availability of our digitized theses and dissertations collection. task force members volunteered to serve in subteams for identified specific tasks in each project phase. information technology and libraries september 2022 navigating uncharted waters | 5 wu, davis-van atta, scott,

scan of similar theses and dissertations digitization approaches previously used by other institutions. the lead for the subgroup created a google sheet that all group members used to document information found in published literature, public documents, and institutional websites. the lead assigned group members to review information from institutions with publicly available data, including: the university of florida, the university of north texas, the university of illinois urbana champaign, brigham young university, william and mary university, texas a&m university, the university of arizona, the california institute of technology, the massachusetts institute of technology, iowa state university, xavier university, texas tech university, and the university of british columbia. group members noted relevant information pertaining to a variety of topics focused on theses and dissertations digitization. one of the most prominent was the institution’s response to copyright permissions. the group tried to determine if the institution required author permission before releasing a digitized thesis or dissertation (the “opt in” option), or incorporated policies and procedures that prioritized taking down digitized theses and dissertations once requested by the author (the “opt out” option). they observed software and hardware specifications used by other institutions—critical data that would inform the technology needed to complete a project of this scale. the group documented the key components of the digitization and metadata workflows, including roles and responsibilities, sequencing of actions, and the implications that policies and procedures had on the process. this data helped the group understand what gaps, common problems, and emerging best practices existed. finally, the group reviewed physical retention and preservation strategies articulated by institutions to ensure it understood the long-term stewardship hurdles and requirements for analog and digital material. information technology and libraries september 2022 navigating uncharted waters | 6 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith based on the assessment of the 19,800 uh theses and dissertations identified for inclusion in the project, the digitization subgroup members determined that several scanners would be required for agility in digitization production. the tdd digitization workflow was designed so that this project could run effectively, in parallel, with existing digitization projects regardless of the need for some theses to be scanned on existing equipment. automatic document feed (adf) scanners were a strategic choice for the rapid scanning of disbound items. two canon dr-g2110 adf scanners were purchased for the project. these scanners were chosen for their scanning speed, scanning quality, ease of use, onboard image preprocessing, and reasonable price point. the canon dr-g2110 can handle a large page stack, approximately 500 pages. theses and dissertations can be scanned on the longer or shorter dimension, which allows faster scanning times. among many innovative features, this duplex scanner simultaneously digitizes both sides of a document, rotates the pages based on text orientation, and auto-crops through preprocessing during the scanning process. this canon adf solution makes more image postprocessing automation possible since the resulting scans match our output expectations with minimal user input. other scanning options were needed for a smaller subset of theses and dissertations that could not be disbound. the digitization team leveraged an existing zeutschel os 12002 planetary scanner for items that could not be disbound. an existing plustek opticbook (po) a300 plus was used for items with foldouts containing graphs, maps, and illustrations that measure beyond 11 inches on the longest dimension. additionally, a plustek opticbook 3800l was purchased to accommodate fragile us letter–sized pages that are not suitable for adf scanning. thin or heavily waxed papers typically do not stand up well to the fast-moving rubber rollers and other internal scanning mechanisms. while the po 3800l provides a much longer scanning time than the po a300, both scanners can scan into the page gutter of bound materials, a useful feature for items with insufficient margins. figure 1. image processing workflow testing on a thesis in limb processing. the green check marks on the left indicate that a page has been processed correctly. information technology and libraries september 2022 navigating uncharted waters | 7 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith the canon adf scanner operates through two pieces of software working concurrently, canon captureontouch v4 pro and kofax vrs (an additional product supplied by the task force’s scanner vendor). some image processing settings are applied in kofax vrs, which communicates with captureontouch v4 pro. both pieces of software were bundled with purchases of the two canon adf scanners. limb processing by i2s was also purchased for the project. limb processing is a powerful mass image processing product that operates through user-built processing workflows that can be applied to multiple folders, creating standardized output suitable for automation. the limb software can transform an imperfect scan into a fully processed, clean derivative with minimal user input, which is especially useful for transforming legacy image data. abbyy finereader server 14 is used to provide quality optical character recognition (ocr) data and features efficient tools for automation, allowing for large ocr processing jobs to be queued and run recursively with minimal user intervention (see fig. 1). with these powerful tools, uh libraries has been able to leverage our existing scanners, new scanners, and advanced software to plan for the timely capture of nearly three million pages of content. the number of theses and dissertations required the implementation of a semiautomatic disbinding system. the spartan 185a paper cutter from the challenge machinery company was purchased to ensure the replication of many clean binding removals. options from several manufacturers were considered for these needs but the spartan 185a offered the cutting power needed to cut millions of pages over the life of the project (see fig. 2). the cutter features several safeguards that protect the operator, such as the lowering of a protective acrylic guard and the requirement of two hands, away from the blade, to lower the blade automatically. uh libraries chose a local cutter blade replacement company that services the equipment quarterly. in addition to the cutter, supplies for binding removal and physical volume management were needed, such as: • x-acto knife and/or utility blades • recycling bins • table brooms and dustpans • disbinding tables • cutting mats • standing mats • letter and legal-size folders • folder holders • surface cleaning materials • carts/book trucks information technology and libraries september 2022 navigating uncharted waters | 8 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith figure 2. (l) thesis scanning test on the zeutschel os 12002; (r) challenge spartan 185a cutter with red numbers indicating blade lowering and cutting safety button order. the physical retention of volumes was considered in the context of the overall preservation of the theses and dissertations collection, including the digital preservation approach to the tdd project. the uh libraries holds two copies of a student’s thesis and dissertation. after consulting with stakeholders throughout the library—such as the university archivist, the dean of libraries and associate deans, and access services’ shelving team for shelf space/storage in different areas of the library building—the task force decided to retain one bound copy of each thesis or dissertation. additional copies will be weeded from the general collection, and the best copy for digitization will be disbound for feeder scanning using the equipment described above. when only one copy of a thesis or dissertation exists in the collection, it will be scanned using a scanner that will not destroy or damage the binding. the retained theses and dissertations collection will be housed in uh libraries special collections in the secure and climate controlled closed stacks. once the tdd task force settled on this retention strategy, the digital projects coordinator, a member of the task force who represents special collections, conducted a full shelf -read of the theses and dissertations already housed in special collections. using a master tracking spreadsheet that was generated from catalog reports for project tracking and pulling, a small team of student workers reviewed over 20,000 volumes to identify missing titles, titles with multiple copies that can be weeded from special collections, and copies with label and/or cataloging errors. missing titles were transferred from the general stacks to special collections, and the items were reshelved in chronological order. a more extensive shelving shift still needs to be completed to move volumes to accommodate additions and finalize the shelf location for all items in this collection, which will no longer be growing or because all theses and dissertations at uh are submitted electronically as of 2014. as part of the shifting project, the items also need to be checked in and/or have their location codes changed in the catalog to reflect their new permanent home in special collections. information technology and libraries september 2022 navigating uncharted waters | 9 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith phase two: workflow development the theses and dissertations digitization workflow starts with pulling physical volumes from shelves. the task force generated a report of all uh theses and dissertations and sorted them by call number so that student workers can pull these volumes from the general stacks in call number order. after the pulled volumes’ records are withdrawn from the catalog system, they are shelved by call number order in the “ready for digitization” section of the tdd shelf in the library basement, close to the digitization lab. volumes are pulled from a section of the library stacks dedicated to the tdd project and loaded onto book carts for transfer to the physical volume processing room. using a custom-built processing table, covers are removed with utility knives and discarded. the text is placed in a folder with a pre-printed label indicating the oclc number and call number of the volume. the spine of each volume is removed with a spartan guillotine. the completely disbound volumes, housed in labeled folders, are then moved on book carts to the scanning room. prior to scanning, physical volumes are grouped in batches of approximately 50 and a text file is created that lists each oclc number in a batch, one per line. a simple executable file reads the text file and creates a batch directory. the batch directory is labeled with the current date in yyyymmdd format and contains a folder for each scanned volume. the scanned volume folders are labeled by oclc number and contain a metadata.txt file that records the volume’s descriptive metadata from the uh catalog system in yaml format: a data carrier that is easily readable for both humans and machines. scanning is performed with one of the two canon dr-g2110 high-speed feed scanners controlled by kofax vrs and captureontouch v4 pro software. before a volume is placed in the scanner, it is checked to ensure that the binding has been completely removed, that there are no pages that have been glued in after binding, and that there are no onion skin pages, irregular page sizes, inserts, or foldouts. if necessary, additional scans for delicate onion skin pages, inserts, or foldouts are performed on a flatbed scanner. page images are output as 300 dpi grayscale or color tiffs, and first pass quality control for completeness, page legibility, and rotation, and cropping is performed in captureontouch. after page images have been captured, a batch is loaded into limb for final processing. scanned volumes are again checked for completeness, legibility, and orientation. text pages are processed as 300 dpi bitonal tiffs. pages with grayscale or color images are processed as such. when batch processing is complete, the documents’ processed signature pages, which include names and signatures of the author, advisor, and committee members, are separated out so they are not included in the final version published online. this step protects the privacy of individuals by not sharing their signature openly over the internet. the tdd project uses abbyy finereader server 14 to generate full text pdfs and a plain text file for each scanned volume. the data in each scanned volume directory undergoes transformations both before and after the ocr processing. the transformations are accomplished with the tdd workflow utility, a ruby command line application. before running a batch through ocr, the archive digitized batch function moves the high-resolution master tiffs to an archive directory and formats the batch directory for the input that abbyy expects. after ocr processing, the archive ocr batch function moves the derivative tiffs used as ocr input to the archive directory information technology and libraries september 2022 navigating uncharted waters | 10 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith as well. in a final process before sending the batch to the metadata unit, the process ocr batch function adds descriptive metadata to the embedded exif metadata of each pdf document with exiftool for improved accessibility. the tdd task force sought to align print materials’ metadata standards with the existing metadata standards applied to electronic theses and dissertations in the university’s institutional repository, largely based on the dictionary of texas digital library descriptive metadata guidelines for electronic theses and dissertations, v.2.22 early on in the project, the metadata subteam reviewed thesis and dissertation records in the institutional repository (ir) as well as marc catalog records in uh libraries’ library services platform, with special emphasis on the metadata elements used, to identify alignments and gaps. after analysis, the team established the crosswalk from marc to the qualified dublin core profile in the ir (see table 2). in july 2019, uh libraries migrated to the alma library services platform. prior to this migration, the task force exported tdd marc records from uh libraries’ former library services platform, sierra, and crosswalked into dublin core metadata fields using the freely available software marcedit. data was further normalized using openrefine. at this early stage, openrefine proved to be a valuable tool for batch editing and formatting metadata and identifying legacy terms or missing data. once the crosswalked data was cleaned up and put into place, standard values for all records were added (see table 3). table 2. metadata crosswalk from marc to qualified dublin core metadata field marc field qualified dublin core element oclc number 001, 035 $a dc.identifier.other call number 099 [n/a, admin use only] author name 100 $a dc.creator title 245 $a $b dc.title thesis year 264 $c

part of the quality control, each volume’s metadata is evaluated against its corresponding metadata record and edited when necessary. in an effort to enrich the metadata available to users and increase visibility of the volumes, information not typically provided in the marc records, such as thesis committee chairs, other committee members, and abstracts, are added to the records using dublin core contributor (dc.contributor.committeemember) and abstract (dc.description.abstract). information technology and libraries september 2022 navigating uncharted waters | 11 wu, davis-van

“thesis” or “dissertation,” as applicable thesis.degree.grantor university of houston dc.type.dcmi text dc.format.digitalorigin reformatted digital in the interest of closely observing copyright best practices, members of the tdd task force, including the digital projects coordinator and the director of the digital research commons, created copyright review guides and applicable rights statements. under these guidelines, theses and dissertations are considered under copyright if a copyright notice appears on volumes created in 1977 and earlier, if the item was created between 1978 and february 28, 1989, and if it was registered with the us copyright office within five years of its creation, or if it was created on march 1, 1989 or later. inserts and other research material provided in the volumes are similarly considered for copyright evaluation during the copyright review process. once a volume has been evaluated for copyright status, an out-of-copyright or in-copyright statement is assigned. in alignment with the uh libraries’ mission to provide valuable research and educational materials, digitized volumes and metadata records are then ingested into the institutional repository.23 in this stage of the process, out-of-copyright volumes are made available as open access materials. due to inherent limitations, in-copyright volumes are access restricted and available solely to the university community. when content is ready for ingest, volumes are moved to the ingest folder and placed in staging directories based on rights status: open access or in copyright. the ingest process is the same for both types of content, but in-copyright content requires additional post-ingest processing, so ingest batch folders are labeled according to rights status for clarity. the tdd workflow utility’s prepare ingest package function is used to create ingest packages in an input format expected by the saf creator, a utility for preparing dspace batch imports in the simple archive format .24 pdf files are copied and renamed in the format lastname_year_oclcnumber.pdf, a csv file is created with descriptive metadata for the batch, and the original files and metadata are moved to an archive directory. the saf creator is then used to create an saf ingest package that is imported into dspace. limiting access to copyrighted content was a necessary component of the project that took some time to solve. the team investigated creating a separate collection for the in-copyright content with access limited to users logged in with uh credentials. the downside to this approach was that the content within the restricted collection was not discoverable to users who were not information technology and libraries september 2022 navigating uncharted waters | 12 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith logged into the ir. in the end, the tdd task force worked with the texas digital library, a consortial nonprofit organization that hosts uh libraries’ dspace repository, to enable restricted access using bitstream authentication with shibboleth. this allows the task force to ingest all tdd project content into a single collection and apply uh authentication to copyrighted pdf documents. in this manner, descriptive metadata for all documents is discoverable, but access to the document content is only available to members of the uh community. applying authentication to bitstreams in the dspace administrative interface is a tedious process involving numerous clicks and dropdown menu selections. selenium ide, a browser plug-in designed for automated web development testing, is used to automate that process in the firefox web browser. after an in-copyright batch has been ingested, the tdd workflow utility’s prepare selenium script function is used to create an automation script for selenium. when loaded in the firefox selenium add-on, the script automatically applies the bitstream authentication steps in the browser for each volume in the batch. the tdd workflow comprises detailed tasks carried out at different units in the library in a sequential routine as an assembly line. tdd activities flow from pulling volumes from shelves to disbinding, scanning, image quality control and ocr, metadata creation and copyright evaluation, and digitized files ingestion into the dspace system. as the tdd task force worked collaboratively to develop and confirm workflows for this complicated process, they documented each section of the workflow in the one-stop tdd workflow google document for easy access and transparency of the overall process.25 the tdd working group members notify each other at completion of tasks at each section. to better track each thesis and dissertation as it moved through the digitization, metadata, and copyright verification workflows, the task force developed an excel spreadsheet tracking system.26 this tracking system lists uh libraries’ theses and dissertation titles, their oclc numbers, dates, and call numbers. it records the tdd volumes pulled from shelves, digitization completed, digitization batch, borrower notes, metadata completed, and other notes. this tracking system provides a channel for the team members to inform each other of completed tasks at each unit and to communicate issues in the working process (see fig. 3). information technology and libraries september 2022 navigating uncharted waters | 13 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith figure 3. a screenshot of a portion of the tdd tracking system. phase three: promotion, communication, and next steps it is important to have strategies for tdd promotion and communication to raise awareness of the online availability of the university’s legacy theses and dissertations. the tdd task force brainstormed elements such as audience, channels, and timeline for tdd communication. theses and dissertation authors and campus users are the two main groups the task force plans to target in its promotion and communication plan. to attract audience attention, the tdd task force will design an online flyer/postcard for dissemination. they are currently collaborating with the uh libraries director of communication, the uh alumni office, the uh graduate office, and the uh division of research to distribute messages to targeted audiences. the task force will communicate tdd digitization progress as they reach important milestones, including the completion of pre-1978 volumes, then at the increments of 10,000 and 15,000 volumes, and once all volumes have been digitized and deposited to the repository. with the disbanding, digitization, and metadata workflows firmly in place, the tdd task force commenced the process of generating digitized versions of uh’s theses and dissertations in 2020. while this process will continue over the next several years, the task force will also fo cus on refining policies and workflows around its copyright and digital preservation activities. the tdd task force has developed a draft copyright policy development document, which outlines copyright determination decisions and access controls for content deemed in copyright. the task force is currently consulting with uh general counsel to ensure its recommended copyright approaches are in concert with university best practices. information technology and libraries september 2022 navigating uncharted waters | 14 wu, davis-van atta, scott, thompson, washington, jones, weidner, ramirez, and smith at the same time, the task force is developing digital preservation procedures to ensure the longterm access, storage, and preservation to digitized theses and dissertations. the group has made some foundational decisions to date. since one physical copy of each title will be retained, allowing for future higher-resolution rescanning if needed, the task force determined that the preservation master file for each digitized thesis or dissertation will be one pdf. this will allow the uh libraries to greatly reduce the ongoing storage costs associated with digitally preserving the tdd collection. throughout 2023, the task force will be exploring ways to sync tdd content to its current digital preservation workflow process, including submitting content to uh libraries’ archivematica instance for preservation curation services such as file fixity checks and normalization, and transferring preserved tdd content to cloud storage for distributed digital preservation. prior to ingesting any content into the institutional repository, the team reached out to the uh’s electronic and information resources accessibility (eira) coordinator for feedback on the accessibility of the pdf documents produced by abbyy. the eira coordinator recommended encoding our pdfs as pdf/a-1a, a standard designed for preservation and accessibility, and introduced the team to the accessibility tools available in adobe acrobat. the adobe acrobat accessibility checker has been useful for identifying and addressing accessibility issues with the pdfs that we are producing. uh libraries web accessibility standards strive to comply with the world wide web consortium’s (w3) web content accessibility guidelines (wcag). combined with the feedback from the uh’s eira coordinator, the current output was reviewed against these accessibility checklists, and areas needing improvement were identified. after several adjustments, the newest output for the project passes a majority of adobe acrobat’s accessibility checker accessibility parameters, with further investigation planned to address weak points moving forward. conclusion the tdd project at uh libraries provides an in-depth view of the planning and workflow processes needed to launch a retrospective thesis and dissertations digitization effort in an academic library setting. collaborating across uh libraries departments, the tdd task force designed a phased approach to identify technology and resources needed to undertake the project, to develop policies, procedures, and workflows to guide the work to its completion, and to communicate about the scope, purpose, and progress of the project to internal and external stakeholders. throughout the planning and development phases, the task force leveraged automation, bibliographic data reuse, and project management tracking to achieve workflow objectives efficiently and responsibly. with the project well underway, the task force will continue refining its processes and working across uh libraries and campus units to ensure it complies fully with copyright and digital preservation best practices. through these ongoing efforts, the tdd task force is ensuring that the original research and scholarship contained in thousands of theses and dissertations are more accessible than ever before—broadening the reach and impact of uh graduates well into the future. funding this project was funded by the

2022. abstract in this paper, we present findings from a three-year research project funded by the us institute of museum and library services that examined how advanced broadband measurement capabilities can support the infrastructure and services needed to respond to the digital demands of public library users across the us. previous studies have identified the ongoing broadband challenges of public libraries while also highlighting the increasing digital expectations of their patrons. however, few large-scale research efforts have collected automated, longitudinal measurement data on library broadband speeds and quality of service at a local, granular level inside public libraries over time, including when buildings are closed. this research seeks to address this gap in the literature through the following research question: how can public libraries utilize broadband measurement tools to develop a better understanding of the broadband speeds and quality of service that public libraries receive? in response, quantitative measurement data were gathered from an open-source broadband measurement system that was both developed for the research and deployed at 30 public libraries across the us. findings from our analysis of the data revealed that ookla measurements over time can confirm when the library’s internet connection matches expected service levels and when they do not. when measurements are not consistent with expected service levels, libraries can observe the differences and correlate this with additional local information about the causes. ongoing measurements conducted by the library enable local control and monitoring of this vital service and support critique and interrogation of the differences between internet measurement platforms. in addition, we learned that speed tests are useful for examining these trends but are only a small part of assessing an internet connection and how well it can be used for specific purposes. these findings have implications for state library agencies and federal policymakers interested in having access to data on observed versus advertised speeds and quality of service of public library broadband connections nationwide. introduction the covid-19 pandemic exposed the severity of the digital divide in the united states. during this time, lack of access to computers and the internet has been highlighted among individuals and families with limited monthly incomes in tribal, rural, and urban communities where broadband is neither available nor affordable. decades of research has shown that this digital divide is further deepened along racial and ethnic lines. wealthier, white, and more educated individuals consistently have higher rates of home computer and broadband ownership. many without th is societal privilege rely on their local public libraries and other community spaces to fill these gaps. the pandemic has also underscored just how significant public libraries have been in addressing people’s need for computers and high-speed internet. last year, for example, mainstream news mailto:critzo@afutures.xyz mailto:crhinesmith@metro.org mailto:jie.jiang@simmons.edu information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 2 organizations shared several stories about children, parents, and teachers all relying on wireless internet access while seated outside in school and public library parking lots, which happens both during and outside library hours.1 much less attention has been paid, however, to the broadband infrastructure and technical support that public schools and libraries need to meet the digital demands of their communities. in 2018, our research team, composed of researchers and practitioners at the simmons university school of library and information science, measurement lab (m-lab), and internet2, received a grant (award #71-18-0110-18) from the us institute of museum and library services (imls). the purpose was to investigate how advanced broadband measurement capabilities can inform the capacity of the nation’s public libraries to support the online software applications and social and technical infrastructure needed to promote the national digital platform.2 in this paper, we present findings from this study, which seeks to address a gap in understanding, particularly among researchers, practitioners, and policymakers, about the speeds and quality of service of public library internet connections across the united states. through our research we learned that there are significant gaps in knowledge about broadband speeds and quality of service measures that are impacting the ability of public libraries to support their communities’ digital needs. in this context, we hope the quantitative data and analysis presented in this paper contributes to the scholarship on broadband measurement in libraries, as well as to expanding awareness and understanding of broadband data. more concretely, we hope this paper helps to raise awareness of the urgent need for shared knowledge about broadband data and infrastructure that supports digital services in public libraries. we begin the paper with a brief review of key studies that have highlighted the important role of public libraries in promoting digital equity, as well as studies that have discussed the importance of measuring broadband connectivity in public libraries. we concentrate particularly on those studies that have sought to elucidate the opportunities and challenges of both connecting public libraries with high-speed internet connections and educating public librarians, other researchers, and policymakers about what is meant by broadband infrastructure and services. we then present our findings from the quantitative analysis of our broadband measurement data, which highlights the ways in which ongoing, locally collected measurements can enhance libraries’ understanding of their internet service and help inform interactions with patrons and it service providers. the paper concludes with a discussion of the contribution of our research to the scholarship, and we briefly discuss the implications for state and federal policymakers interested in better understanding the role that library broadband measurement data can play in promoting healthy digital equity ecosystems. literature review digital inclusion and broadband measurement in public libraries public libraries in the united states have been committed to bridging the digital gap by providing free public access to computers, internet, and digital literacy skills for decades.3 for example, in their study of how public libraries respond to inquiries about the digital divide through participatory forms, schenck-hamlin, han, and schenck-hamlin found that public libraries have been recognized as the “first and last” resort for internet access particularly “for those unable to afford high-speed connections at home.”4 further, bertot, real, and jaeger affirmed this idea with their digital inclusion survey data, collected over several years, by stating, “america’s public libraries are an important force for bridging this (digital) divide, with 62.1% of these outlets information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 3 reporting that they are the only free providers of internet access inclusive of computers in their communities.”5 in addition to providing public access to computers and the internet, us public libraries have placed an emphasis on promoting the general public’s awareness and skills around broadband through delivering free digital literacy training sessions, as well as hosting civic discussions around the topic of broadband connections with their patrons.6 to further illustrate how public libraries narrow the digital divide, deguzman, jain, and loureiro explained that telemedicine has become a new norm in today’s medical visits, which quickly became a reality during the covid-19 pandemic. in their article, the authors show how public libraries can play a critical role in bridging this “digital health divide” that exists in many communities.7 as a bottomup means to promote digital inclusion in the us, the role that public libraries have played to promote digital inclusion and equity cannot be overlooked. however, as jaeger et al. explained in their study on how public libraries address the digital divide and digital inclusion, “one curious constant across policy approaches to digital divides in many, though not all, nations has been the failure to involve librarians in the formulation of definitions, policies, or other aspects of the policy-making process.”8 it is within this space that public librarians and the technological staff who support them can play an important role in co-designing the tools, skills, and knowledge needed to better understand broadband in public libraries. broadband measurement in public libraries many public libraries, particularly small, rural, and tribal libraries, face ongoing challenges in gaining accurate information about their broadband speeds and quality of service. this lack of information can limit their capacity to provide a wide range of applications and services to the community. as bertot, real, and jaeger concluded, one of the big challenges that public libraries have been dealing with is that the speed of public library internet connections “can vary significantly according to local population density.”9 in reaction to this situation, public librarians have shown great interest and need to acquire knowledge about their libraries’ current broadband performance.10 digital inclusion scholars have proposed topics that future research on public libraries and broadband measurement should explore.11 these topics include how to better inform public librarians in order to assist them in planning, as well as how to deliver sufficient and quality broadband connections to the community. other topics include looking at how to help public libraries justify the need for more workstations and bandwidth using data coming from “empirical measures, especially longitudinal measures.”12 these and other questions remain largely unanswered in the academic literature. the measuring library broadband networks (mlbn) project and research design research questions and significance of study our research sought to address this gap in the scholarship on broadband measurement in public libraries through the following research question: how can public libraries utilize broadband measurement tools and training materials to develop a better understanding of the broadband speeds and quality of service that public libraries receive? in response, our research team gathered quantitative data from an open-source broadband measurement system that was both developed for this study and deployed at 30 public libraries across the us. our research is significant because answers to these questions can help strengthen public libraries as essential anchor institutions and partners in providing data to address the digital needs of their communities. the findings from our study can also assist public libraries in responding to the challenges of developing a more integrated, equitable, and dynamic set of infrastructures for delivering public computing access and digital library services. information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 4 project overview and research design the measuring library broadband networks (mlbn) project (https://slis.simmons.edu/blogs/mlbn/) was originally conceptualized to be completed in four phases during the two-year grant period. during the first phase, we organized a “participatory design” workshop with our 10 first-year public libraries who agreed to serve as part of our research panel on the project.13 findings from our analysis of the qualitative data gathered during the workshop revealed that public libraries wanted access to broadband measurement data in order to: (1) better communicate with their patrons about their library’s broadband connectivity, (2) respond to their communities’ digital needs, and (3) justify the importance of robust internet connectivity to their funders.14 our analysis revealed early on in the project that knowledge gaps existed around the performance of public library broadband networks, patron and staff experiences using the library’s internet connection, and the meaning and value of measurements such as speed tests. during the second phase of the project, we applied what we learned from insights gained during the workshop to our site visits with the 10 participating first-year public libraries. during our fieldwork at the libraries, we sought to interview four different groups of people: (1) library staff, (2) library administrators, (3) it staff, and (4) it administrators. the purpose was to gain multiple perspectives on the same sets of questions, which would provide additional qualitative data to help answer our research questions. in a few of the libraries, the library administrator was also the primary it professional on site. in other words, depending on the size of the organization, librarians often wore several hats, which is certainly not uncommon for small, rural, and tribal libraries. in addition to conducting interviews with these four groups, we also held focus groups with patrons on site at each of the libraries. during this process, we were able to learn more about the context, character, and communities of our partner libraries and gain a better sense of what it is like to work at and/or be a patron of each library, as well as why public libraries might need an open-source broadband measurement system. the other main goal during this phase was to learn more about and document the process of installing our broadband measurement devices. through this process, we gained additional insights into the nuances of the network configurations at each location and refined our device configurations and setup instructions in response. ultimately, we sought to identify potential barriers to the measurement devices working properly in the networks of our second-year libraries, when we would not have the luxury of being there in person. at the conclusion of the research program in march 2021, we asked participating library and/or it staff to complete a final evaluation survey. twenty libraries responded to a range of questions, two of which related to their understanding of the library’s internet connectivity and network management practices: “is there an overall download and/or upload cap on the connection to the entire library building?” and “is there a cap on individual devices using the internet at the library?” eight libraries responded to one or both of the above questions; their responses are in table a.2 in appendix b. training manual during phases 2 and 3, we worked with carson block, a well-known library technology expert and consultant who helped us to develop our mlbn training manual (https://dataverse.harvard.edu/dataset.xhtml?persistentid=doi:10.7910/dvn/8xxxzq). the https://slis.simmons.edu/blogs/mlbn/ https://dataverse.harvard.edu/dataset.xhtml?persistentid=doi:10.7910/dvn/8xxxzq information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 5 development of the manual was led by chris ritzo, carson block, and colin rhinesmith to assist our second-year participating public libraries in being able to install the measurement devices on their own. the manual provides a comprehensive overview of our mlbn project, including what we learned in the first year of the project about why public libraries would want to measure broadband at their libraries. section 2 focuses on the setup instructions that public libraries would need to install the devices to measure both wired and wireless internet connections. we also provided details on the hardware used, device management, and data collection, as well as the data visualization platform developed for the project, which allows public libraries to access and use the broadband data gathered from the devices installed on their network. the manual includes complete information about how the measurement platform used in this study can be set up independently for future use by any library, institution, or individual. we knew this manual would be essential for scaling to the 60 total public libraries for our project and for any additional library after the end of our grant. final cohort of participating libraries libraries participating in this research were recruited primarily through the suggestion of the project’s advisory board, many of whom represented state library agencies, regional research and education networks, or other intermediary organizations working with or supporting public libraries. though the covid-19 pandemic limited our ability to scale up to our goal of 60 libraries, ultimately 30 libraries were recruited to participate in the research. appendix a lists the final cohort of participating libraries, the specific branch where measurements were conducted, the city, state, and the library’s imls code. broadband measurement data collection quantitative measurements of the network connections at participating libraries were collected using the murakami software developed by m-lab, running from a dedicated, on-premise measurement computer/device.15 this software provides tests from two large platforms for crowdsourced speed tests: m-lab’s network diagnostic tool versions 5 and 7 (ndt) and speedtest-cli, an open source client using the ookla platform.16 ndt is a network performance test of a connection’s bulk transport, conforming to the internet engineering task force’s (ieft) rfc 3148.17 m-lab provides two ndt testing protocols (ndt5 and ndt7), each measuring different aspects of the transmission control protocol (tcp).18 all versions of ndt measure upload and download speeds and latency using a single tcp stream, between the computer running the test and the nearest m-lab server. ookla is a commercial company that created the network performance test speedtest.net.19 ookla’s test also measures upload and download speeds, as well as latency, but provides the option to measure using a single tcp stream or using multiple streams. the primary differences between these two platforms’ tests are the use of single or multiple tcp streams and the location of testing servers.20 at each location (with a few exceptions), two devices were configured using network details supplied by library or it staff and shipped to the library with setup instructions (in some cases, depending on network complexity, only one device was installed). one device was connected to the switch or router where internet service connected the location (egress). the other device was connected to an available switch port on the same virtual local area network (vlan) as wifi access points. the intention was to measure the capacity of the entire location using the egress device, and the capacity of a single wifi access point (ap) to serve multiple patrons using the wifi ap device. once connected, each device ran tests approximately six randomized times within each 24-hour period. information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 6 each murakami device ran four tests: ndt 5, ndt 7, ookla single-stream, and ookla multi-stream. each test result was exported to an archive in google cloud. this data was imported into bigquery and analyzed in datastudio.21 data from the 2019 public libraries survey (pls) from imls was also included to describe each library’s locale, service population, and number of public computers, annual computer use sessions, and annual wifi sessions reported.22 public data provided by both ookla and m-lab for the counties in which each mlbn library was located were loaded to compare each platform’s reported aggregate measurements for the surrounding area to the measurements conducted at the libraries.23 aggregate public data for the surrounding counties in our analyses excluded all measurements from the libraries themselves. along with the data itself, specific details on our data import, cleaning, and analysis are provided in our publicly available mlbn dataverse (https://dataverse.harvard.edu/dataverse/mlbn), hosted by harvard university. limitations the covid-19 pandemic created challenges for the research team in scaling up to 60 libraries, as was planned at the beginning of the project. therefore, we had to limit our outreach and engagement during 2020. when we asked the final 30 public libraries that were able to participate in the research whether they had closed their doors during the pandemic, all of them said yes. however, all the libraries reported that they continued to provide wireless internet access, even though their buildings were closed to the public during this time. although we were unable to scale up to 60 public libraries, we were still absolutely thrilled with the response we received from the libraries that were able to participate. the ndt 7 tests in our program uncovered a now-resolved bug where measurements were limited by the performance of our selected premise devices, which lack proper support for encryption.24 this is observable in some of our data as a large jump in measured speeds from ndt 7 after november 1, 2020. the jump in measured throughput from ndt 7 tests after november 1, 2020 reflected when encrypted ndt 7 tests were disabled and began running unencrypted.25 findings individual libraries’ data data collected at each library is provided in an interactive mlbn datastudio report, along with summary information about the library from the 2019 public libraries survey.26 aggregated download, upload, and latency metrics from measurements conducted at each library can be viewed on page 2, individual library data (see figure 1 for an example).27 https://dataverse.harvard.edu/dataverse/mlbn information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 7 figure 1. individual library data page for andover, massachusetts.28 a unique feature of the report is a map of server locations to which tests were conducted. this feature demonstrates the different topologies of the ookla and m-lab platforms and enables analysis of measurements to specific servers. if a library’s internet service provider (isp) hosts an ookla server, it can be selected to display only measurements of the isp’s network, as shown in figure 2. the federal communications commission (fcc) distinguishes this topology as on-net, when the server and client are both within the same network, in contrast to off-net, where the server and client are in different networks.29 figure 2. individual library data page for clarkston, michigan, merit networks’ nearest ookla server selected.30 information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 8 by selecting all servers, we can observe the wide geographic range of ookla servers used. conversely, when we select one of the ndt tests, we can see that m-lab servers are only hosted in large metropolitan areas, as seen in figure 3. this demonstrates key differences in the server locations of these two measurement platforms and how the data from each relates to the fcc’s national broadband standard.31 clarkston, michigan—all ookla servers selected32 clarkston, michigan—all m-lab servers selected33 figure 3. test server locations for clarkston, michigan—all ookla and m-lab servers selected. additional aggregate speeds are provided on the individual library data page to communicate general measurement trends over time: maximum upload and download speed by month, day, hour, and weekday (see figures 4–7). this allows a library to confirm advertised speeds, as seen in figure 4 where the connection at clarkston, michigan, was measured consistently at just under 100 mbps symmetric download and upload. we also observe where measurements are not always consistent, as seen below in figures 5 and 7. in figure 5 we observe a dip in the upload median for westchester county, new york, in late june 2020, and a drop in upload median in late october 2020. with additional information, a library could correlate these observations with network outages, service changes, or network management changes. for example, the change in october 2020 could have been a network management change or service change to 200 mbps symmetric. in figure 7 we observe a trend that many librarians will recognize: a slight dip in median speeds over the peak hours of use. information technology and libraries september 2022 measuring library broadband networks | ritzo,

additional local knowledge about network use, conditions, and events, library and it staff can use ongoing measurements to confirm and explain service changes or uncover issues that are not previously known. many mlbn libraries sought ongoing measurements of internet service to confirm service delivery levels, and some shared their expected service speeds in our final program evaluation survey. the list of libraries that shared their expected service levels are listed at the end of this paper. using these reported speeds as an example, we can observe where the overall measured speeds were consistent with the service levels and where they were not, using the ookla multi-stream measurements. bennington (vt) free library reported a 100 mbps symmetric connection as their expected service level, and the monthly maximum speeds range between 93 and 98 mbps.38 similar results were seen in live oak, georgia; monroe county, michigan; and sheridan, arkansas.39 in other cases, the reported service levels did not match the measurements. in pasco county, florida, measurements indicate a 50 mbps symmetric connection where the reported service level was 100 mbps download and 25 mbps upload.40 and in ventura county, california, our information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 11 measurements confirm an ~300 mbps symmetric connection but the reported service level was 1 gbps symmetric. finally, in several cases measurements may confirm anomalies or changes in the library’s internet service. in these examples we do not have local knowledge of changes in service or events that might explain anomalies observed in the data, but we can nonetheless observe that a change happened and make an inference about the causes. some examples include: • graham county, arizona—possible service delivery change in may 2020 from ~100/10 (download/upload mbps) to ~300/3041 • traverse city, michigan—possible service delivery change in january 2021 from ~80/5 to ~300/2042 • waltham, massachusetts—change to symmetric download and upload in november 2020 from ~50/25 to ~50/5043 • truro, massachusetts—observed changes in symmetry of upload and download measurements in june 2020 and march 2021 are perhaps indicators of testing changes in network management to adapt to changing needs44 • westchester county, new york—observed dip in some upload measurements in late june 2020 at specific times of day for unknown reason45 comparing average monthly maximum speeds the final two pages (5 and 6) of our data studio report display the maximum overall speeds and the average monthly maximum speeds measured for each library, filterable by imls code, access media, and type of isp.46 figure 8 shows a report for the average maximum speeds per test at libraries connected with fiber. figure 8. average maximum speeds per test measured at mlbn libraries connected with fiber. information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 12 comparison of measurements and related data to support increased understanding of network measurement within the public library community, we also compared measurements from the public libraries that participated in our study to the public data of crowdsourced measurements from the two large scale internet measurement platforms used in our research measurements, ookla and m-lab. we can observe the differences or similarities in measurements between the tests conducted from the libraries’ premise devices and the publicly released data in aggregate for the surrounding county. the weighted average speeds and latency are provided by quarter, since ookla’s public data limits more granularity. figure 9. comparing individual library data to public datasets—twin falls, idaho, 2020 q4.47 on page 4 of the data studio report we can observe whether the measured speeds in mlbn libraries were lower or higher than measurements from the surrounding county (see figure 9), along with the percentage difference between the two sources (see figure 10).48 while these differences are interesting to observe, and in some cases seem quite pronounced, this is not a finding that explains whether libraries are getting better or worse speeds than their communities. this is a coarse comparison that we might think of as a kind of litmus test for further inquiry, rather than findings that tell a definitive story. ookla public data aggregates all measurements from all isps together, while measurements from mlbn libraries are from one. a subscription to ookla speedtest intelligence might enable more direct comparisons on a per isp basis. information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 13 figure 10. mlbn data studio report, page 4—was public data or library data higher or lower? discussion our research builds on the digital inclusion survey that used a version of the ookla test in a supplemental speed test study in which, “libraries were asked to run the speed test when the library was closed, during regular hours of operation, and when usage was light, normal, or heavy, by the librarians’ estimation.”49 the software created by mlbn to collect ongoing, randomized measurements extends the idea of the digital inclusion survey’s supplemental speed test, making it a source of monitoring data that can be correlated with each location’s connection plans, service tiers, costs, and other metadata. this approach aligns with the methods used by the fcc by using a dedicated, on-premise device.50 the mlbn system also goes further, providing a framework for any open-source measurement to be added as an available test. since the conclusion of our research, several new tests have either been added or are being considered. 51 as new measurement tools and analyses are developed by the research community, the mlbn system can incorporate them and bridge network science researchers’ understandings to anchor institutions and the general public. while speed tests have been used in this research and its predecessors, we find there is a gap in public understanding about what these tests can tell us. one important outcome of our study is that understanding the experience of using the internet, measuring it, and regulating it all need additional measurements and approaches that go beyond speed tests alone. speed tests and the platforms that support them are very different. internet service plans may focus on upload and download speeds, as does telecommunications regulation at the fcc, but these tests offer only simple and incomplete assessments. the ookla and m-lab platforms provide two different controlled experiments designed to measure internet protocols and performance for different segments of the internet’s topology. they both use data generated specifically for the measurement itself. but these tests do not measure our experiences using the internet in general. for that we need network science researchers to develop new measurement methods and analyses. we advocate for even more nuance and additional metrics in the measurement and understanding of internet service beyond speed. this perspective aligns with the research er and network science community who are designing new measurements to account for user experience, content delivery, and latency issues, all of which are often incorrectly assumed to be measured by speed tests.52 information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 14 we took the approach of using multiple tests and platforms to provide complementary measurements of different aspects of delivered internet service. if we need to confirm advertised service levels, we can look at the ookla test data. in this analysis, we used the average monthly maximum speeds as measured by the ookla multi-stream test since it was used in the digital inclusion survey and most closely aligns with isps’ terms of service.53 m-lab’s ndt, on the other hand, provides a diagnostic measurement for how well the underlying tcp protocol is performing over the measured path. that measurement path for m-lab tests always traverses the boundaries between networks. if we want to assess our isp’s connectivity to the internet beyond the last mile network it maintains, we can examine the ndt data. however different the methodologies and measurements of ookla’s speed test and m-lab’s ndt test are, we agree with the internet measurement community that measurements of throughput or speed should not be the only focus of assessing a connection’s quality, and a broader public understanding that includes other measurements and nuances needs to be cultivated. 54 researchers’ understanding of the usefulness of both ookla and ndt measurements is not static, as recent analyses of their public datasets have shown.55 the research community is also exploring new metrics derived from various data sources that may eventually provide analyses that speak to user experience of using the internet, as well as other technical factors that can influence performance such as latency, bufferbloat, and responsiveness.56 what does this all mean for public libraries? building on the speed test used in the digital inclusion survey, the mlbn measurement system enables communities to collect ongoing measurements using a dedicated premise device, leveraging available open-source measurement tools, instead of running periodic or occasional tests. using this longitudinal data, libraries can confirm expected service levels using ookla test results, uncover where there is a mismatch in understanding of service levels or network management practice, or compare a library’s measured service to the surrounding community using public data sources. additional measurements like m-lab’s ndt can assess a library’s connectivity beyond the isp’s network. the resulting measurements are useful for interrogating the differences in platforms, their tests, and regulatory or funding benchmarks. but while speed tests can provide useful metrics for understanding general trends and anomalies, an appropriate understanding of what they do and do not measure is also needed. speed tests demonstrating advertised levels do not necessarily mean that users of that network will not experience slowness as content is delivered to their computers over the same connection. as the federal government prepares to outlay infrastructure dollars to states to improve internet access and service quality, libraries and other public institutions in their states will need specific data and understanding of its nuances and differences. conclusion in this paper, we sought to promote greater understanding about the speeds and quality of service of public library internet connections, an understudied area within library and information science, as well as among broadband policymakers. library staff and administrators need information to understand and communicate about a library’s network capacities, management practices, and diagnostic or monitoring information. the availability of measurements from different sources can help build shared understanding about a library’s internet connectivity between library staff and it or network administration personnel. and while speed tests are admittedly limited in what they can tell us about internet capacity, library staff who have access to information technology and libraries september 2022 measuring library broadband networks | ritzo, rhinesmith, and jiang 15 these types of measurements, as well as other information provided by a library’s it staff, would be better equipped to engage with patrons around questions of internet stability and capacity in support of the library’s mission. from our observations of the data collected, the mlbn measurement system can be used to enhance understanding of the library’s internet service and network management. for the subscribed service levels identified at mlbn libraries, ookla measurements confirm whether the library’s measured connection speeds matched the expected service levels and when they did not. when measurements are not consistent with expected service levels, libraries can observe the differences and correlate this with additional local information. ongoing measurements conducted by the library enable local control and monitoring of this vital service and support critique and interrogation of the differences between internet measurement platforms, their topologies, tests, and data, from the perspective of the library doing the measurement. speed tests are useful for examining these trends but may not always be indicative of a user’s experience accessing and using internet content and services. new research and leadership from the internet measurement community are needed to provide more nuanced and authentic assessments of both network performance and user experience. emerging research and analyses published openly can be added to the mlbn system to support increased public understanding of internet connection quality and user experience. we hope this paper and our research will help support public libraries interested in ongoing measurement and assessment of their internet service, as well as contribute to discussion of the implications for state and federal policymakers interested in better understanding that public libraries play a key role in their local digital equity ecosystems. acknolwedgments funding statement this work was supported by an award

useful to the requester. the improvement of the user experience with the digital library of the university of novi sad dissertations (phd uns) through the personalization of search results representation is the aim of the research presented in this paper. there are three groups of phd uns digital library users: users from the academic community, users outside the academic community, and librarians who are in charge of entering dissertation data. different types of textual and visual representations were analyzed, and representations which needed to be implemented for the groups of users of phd uns digital library were selected. after implementing these representations and putting them into operation in april 2017, the user interface was extended with functionality that allows users to select their desired style for representing search results using an additional module for storing message logs. the stored messages represent an explicit change in the results representation by individual users. using these message logs and elk technology stack, we analyzed user behavior patterns depending on the type of query, type of device, and search mode. the analysis has shown that the majority of users of the phd uns system prefer using the textual style of representation rather than the visual. some users have changed the style of results representation several times and it is assumed that different types of information require a different representation style. also, it has been established that the most frequent change to the visual results representation occurs after users perform a query which shows all the dissertations from a certain time period and which is taken from the advanced search mode; however, there is no correlation between this change and the client’s device used. introduction in order to place their current work within a framework of previous methods or identify research gaps, researchers often need to identify and study previous research. discovering information on the web is not always a trivial task. many systems allow scholars to search for research papers, dissertations, and other technical reports, providing at the same time relevant recommendations to users based on their areas of interest or previous searches. although web search engines are considered a superior solution to more specialized digital library systems, these specialized systems may provide more benefits in specific conditions, e.g., when searching for dissertations in specific languages, or by affiliated countries or institutions.1 nowadays, digital libraries are widely used by diverse communities of users for diverse purposes.2 xie and colleagues conducted an analysis in 2018 to compare similarities and differences in perceptions of the importance of mailto:ljubomir.paskali@gmail.com mailto:lidija.ivanovic@uns.ac.rs mailto:gkapi@cs.ucy.ac.cy mailto:dragan.ivanovic@uns.ac.rs mailto:bdimicsurla@raf.edu.rs mailto:surla@uns.ac.rs information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 2 different digital libraries evaluation criteria by heterogeneous stakeholders in academic settings.3 specifically, they surveyed three groups of stakeholders (scholars, librarians, and digital library users), and through their analysis of the survey’s responses, they identified differences in opinions not only between user expectations and the digital library practice but also between what is desirable and what is possible in the academic environment. regardless of whether more general (i.e., web search engines) or more specific (i.e., digital libraries) systems are used, the presentation of search results to users is important. it significantly affects how they perceive the system and may reduce or increase the chances of using the system and the frequency of use, as usability is an important aspect in any system. the visualization of search results may be adapted to user needs. presenting results either in a textual or an alternative format depends on how users respond to the alternative presentations of the system and this process is followed in different domains, such as recommender systems.4 this can form part of a personalized context-aware system that considers users’ environment, history, and interaction with the system in order to act proactively and adapt the presentation of search results to each user. based on the gaps identified above, the focus for this study is the improvement of the user experience with the phd uns digital library through the personalization of the offered service for system users. it is necessary to provide the user with a choice between textual and visual search results representation according to user preferences and needs. this study reveals a new way of presenting search results that has been analyzed, designed, and implemented by the authors. more concretely, presentations of the bibliographic metadata in a standardized citation style (harvard style) and bibliographic formats (marc 21, dublin core, etd-ms) have been analyzed and implemented. word cloud format is widely used in different systems and this representation has been implemented in the phd uns system. finally, it is necessary to determine if the initial search results representation should be stored in the history of users’ queries, device types, and search mode. users have the ability to provide their feedback on the visualization of the search results, therefore indicating if they prefer a textual or new visual results representation (by changing search results representation style). the feedback received is used to adapt the results representation based on the user preferences. this component represents the first step towards a completely personalized system, in which different contextual parameters will be used for providing a personalized context-based user experience. at this point, user feedback is used for personalization, search results representation, and subsequent system use. a preliminary version with preliminary results regarding the word cloud component is described by kapitsaki and ivanovic.5 in respect to this previous work, we are presenting the evolvement of personalization in the phd uns system and a more thorough evaluation that allows us to perform statistical analysis and draw more generic conclusions. accordingly, the motivation for this research is the personalization of the search results representation of a digital library, and the research questions to which this research should provide answers have been identified. we are discussing our results based on these questions: 1. rq1: what are the users’ profiles of the phd uns digital library? 2. rq2: how could search results best be presented to different users within phd uns’s digital library collections? 3. rq3: can the search results representation with phd uns’s digital library depend on the history of users’ queries, device types, and search mode? information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 3 related work dosird uns the dosird uns project (http://dosird.uns.ac.rs/) was launched in 2009 with the aim to develop software infrastructure for the research domain of the university of novi sad (uns). the cris uns system (www.cris.uns.ac.rs) is the first result of this project. this system represents the information system of the research domain of the uns. the development of the system started with the beginning of the project in 2009 and is still active. the digital library of theses and dissertations (phd uns), which is the topic of this paper, is integrated within cris uns. the complete cris uns system was developed in accordance with the recommendations of the eurocris (www.eurocris.org) non-profit organization. systems which contain the published scientific results were analyzed and, on the basis of these analyses, a set of metadata describing the scientific and research result in cris uns was created. 6 a paper by ivanović et al. described the cerif compatible data model based on the marc 21 format which maps part of the cerif data model to the marc 21 format data model. 7 the marc 21 format is a standardized format for storing bibliographic data. cris uns has been built on th is model. the system architecture and implementation are described in previous publications.8 the development of the digital ph.d. dissertations library (phd uns) began in 2010. in december 2012, the senate of the university of novi sad approved the commissioning of a public service for the search of a digital library of dissertations defended at the university (https://cris.uns.ac.rs/searchdissertations.jsf). phd uns has been implemented with the following characteristics: • the digital library of e-theses is integrated into the information system of the scientific research activity of the university of novi sad (cris uns). • the digital library is cerif compatible, that is, it can exchange metadata with cerifcompatible systems of scientific research activity. • e-theses are described by a set of metadata which includes all the metadata prescribed by the dublin core and the etd-ms metadata format, that is, the system can exchange the data in dublin core or etd-ms format via the oai-pmh protocol. • the digital e-thesis library has a data model and architecture that can be easily integrated with a bibliographic system based on the marc 21 bibliographic format. • the user interface allows a user to enter the thesis and dissertation data without knowing the standardized metadata formats on which the digital library is built. the integration of phd uns within cris uns involved the following four steps: 1. the cris uns data model has been extended with entities and properties for describing phd theses in accordance with cerif, dublin core, and etd-ms data models.9 2. the cris uns software architecture and user interface has been extended in order to support basic functionality of cataloguing theses.10 3. theses’ metadata have been imported from the previous source.11 4. the web page for searching among the collection of theses has been implemented.12 http://dosird.uns.ac.rs/ http://www.cris.uns.ac.rs/ http://www.eurocris.org/ https://cris.uns.ac.rs/searchdissertations.jsf information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 4 searching personalization the findings and analysis of scientific results described in papers, theses, and dissertations is an important part of research activities in the scientific community. therefore, the use and development of the tools and the bibliographic systems which enable advanced search is becoming increasingly more common. the personalization of search results can include automatic recommendations to users.13 moreover, part of search personalization refers to the personalization of results representation. similar to popular web search engines like google, the way the search results are represented is very important to users. the way the results are represented can affect user perception of the system and the frequency of its use. the results can be presented to users in formats other than textual in order to improve the user experience in search tools, as well as to improve access to finding information and in recommendation systems.14 ferran and colleagues described browsing and searching personalization systems for digital libraries.15 their approach is based on the use of ontologies for describing the relationships between elements that determine the functionalities of the desired personalization system. those elements include the user’s profile, including navigational history and the user preferences, as well as the information collected from the navigational behavior of the digital library users. such a personalization system can improve digital library users’ experience. sebrechts and colleagues presented a controlled comparison of text, 2d, and 3d approaches to a set of typical information seeking tasks on a collection of 100 top ranked documents retrieved from a much larger document set.16 the conducted experiments included 15 participants. the study revealed that although visualization can assist the reduction of the mental workload for interpreting the results, these reductions and their acceptance depend on an appropriate mapping among the interface, the task and the user. in relevance to the above, our approach lies in the area of 2d display of information (see the visual results representation section later in this article), but instead of focusing on basic text information we have adopted newer approaches found in word clouds. bowers and card analyzed visualization in the framework of database search. 17 soliman et al. presented an approach for the clustering of search engine results that relies on the semantics of the retrieved documents.18 the approach takes into consideration both lexical and semantic similarities among documents and applies activation spreading tech nique, in order to generate clusters based on semantic properties. nguyen and zhang proposed a model for web search visualization, where physical location, spatial distance, color, and movement of graphical objects are used to represent the degree of relevance between a query and relevant web pages considering this way the context of users’ subjects of interest.19 a word or tag cloud is a visual representation of word content commonly used to represent content in different environments.20 several past works have introduced various algorithms for the tag selection or new ways for the word cloud creation. 21 tag clouds have been used in pubcloud for the summarization of results from queries over the pubmed database of biomedical literature.22 pubcloud responds to queries of this database with tag clouds generated from words extracted from the abstracts returned by the query. the authors found that the descriptive information is this way provided in a better way to users. however, the discovery of relations between concepts is rendered less effective. information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 5 context awareness context awareness is a part of many systems in various domains, where the application or system functionality adapts to the context of use, such as in mobile computing or pervasive computing applications.23 the first definition of context was given by abowd and colleagues, where they defined context “as any information that is relevant to the user, to the system and to any interaction between the user and the system.”24 applications utilize context data in order to provide context-aware services to users. context information, such as user location or user preferences, are used to adapt the application functionality or presentation to a specific user. mobile computing and pervasive computing offer the necessary information from mobile device sensors and in users’ environments for context-aware application provision.25 fink and kobsa claimed that personalization may adapt various features in order to address the specific needs of each individual.26 many systems utilize users’ search history in order to offer personalized search in the framework of the web information retrieval systems. yoganarasimhan found that personalization based on short-term history or within-session behavior is less valuable than longterm or across-session personalization.27 behnert and lewandowski analyzed the application of web search engines ranking approaches on digital libraries, and they argued for a user-centric view on ranking, taking into account that ranking should be for the benefit of the user, and user preferences may vary across different contexts.28 frias-martinez and colleagues defined an approach to constructing personalized digital libraries. adaptive digital libraries automatically learn user preferences and goals and personalize their interaction using this information.29 based on previous work, frias-martinez and colleagues developed a personalized digital library to suit the needs of different cognitive styles. 30 contribution of our work we share similarities with previous work in terms of techniques used, as for instance the harvard reference style, standardized bibliographic formats (marc 21, dublin core, etd-ms) and word clouds, which have been used in other systems for representation of search results in order to improve the user experience. however, in contrast to previous work, we apply techniques in a specific context for a serbian digital library, allowing automatic adaptation for the representation of search results based on a user’s type, history, and reaction. those search results representations are implemented and integrated within a real system (phd uns) and are tested with real users’ feedback. that users’ feedback is analyzed using elk stack technologies, making our main conclusions useful for similar systems and future research on personalization in digital libraries. methodology the main requirements for implementation of the phd uns digital library were for the system to be compatible for integration with other systems of scientific research activity, support for data exchange in different standardized formats, and provision of representation of the results to users of different categories and profiles (researchers, scientists, librarians, users from outside the academic community, etc.). for these reasons, existing formats for representation of references, bibliographic metadata formats, as well as techniques for visual representation of textual publications, were analyzed. the format adopted for the representation of references was harvard-style implemented with the freemarker template. freemarker information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 6 (https://freemarker.apache.org/) is an open-source template engine for java that assists in separating the web user interface from the main system functionality, following the mvc (model view controller) pattern. the analysis established that it was necessary to implement the search results representation in three bibliographic formats: marc 21, dublin core, and etd-ms. for each of these formats, appropriate mappers/serializers were made which transform the data from a database into the xml (extensible markup language) representation of the previously mentioned bibliographic formats. for visual representation, word cloud style was adopted. a component for generating word cloud images was implemented and integrated into the phd uns digital library. when presented with search results, users are able to choose which desired representation format is stored and used as preferable for the given user in future search results representations. a logging system was implemented to assist with this; this module is invoked when the user changes the default data view mode. received messages are preprocessed for the purpose of analyzing messages and obtaining a more accurate evaluation. the aim of the analysis of the messages on the work of the phd uns system is to obtain the desired statistics: • distribution of used representation styles • top queries executed before changing into the textual style, as well as into the visual style • distribution of devices used before changing into the textual style, as well as into the visual style • distribution of search modes before changing into the textual style, as well as into the visual style these statistics are analyzed to determine the user behavior patterns depending on the type of search (basic or advanced), the search device used, the executed query, etc. based on the established patterns it is possible to determine the representation style for future searches of the new users. the results of the analysis are graphically represented using elk stack technologies and are presented below in the evaluation section. the methodological approach is shown in figure 1. the rest of this paper is organized in accordance with the methodology steps shown in figure 1. https://freemarker.apache.org/ information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 7 figure 1. the methodology of the study presented in this paper. information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 8 analysis of search results’ representation styles textual representation for the needs of the phd uns library, three types of search results’ textual representation for three types of phd uns users were analyzed: reference representation. a citation style is defined as a set of rules for citing sources in academic writing and those rules prescribe style for in-text citations, as well as style for reference representation in the references’ list. this textual approach is intended for users from the academic community—researchers, teaching staff of universities, and phd students. since the majority of phd uns users belong to this group, this is the default representation in a textual representation of the search results. this group of users is familiar with this type of representation. from this type of representation, the users can easily recognize basic data of interest and can use this representation for citing and referencing the dissertations which have been retrieved as a result of executing a query. taking into account that there are currently many different styles for representing references and citations (e.g., apa, mla, harvard, vancouver, and chicago, among others), and that they might change in the future with the emergence of new trends in science (for example, the emergence of open science and the need to cite data sets, not just publications), it is necessary to create a scalable component for representing the results in a form of a reference. based on this analysis, we decided that the architecture of this component will be based on freemarker, which makes the introduction of new templates for the output format easier, and that the first freemarker template should be created for harvard style. structured representation. this textual approach is intended for users outside the academic community who want to search the digital library. this type of representation represents only the data from the digital library database in a legible format that is represented in the web browser. bibliographic formats representation. this textual approach is intended for librarians who are in charge of entering and maintaining data in the digital library. in addition to one central library of the university of novi sad, there are libraries in every department within the university. most of these libraries use the bisis library system, which is based on marc format. therefore, it can be concluded that the majority of the librarians who enter data into the phd uns library are familiar with the marc format. librarians can use the representation of metadata about dissertations in the marc 21 format to check if all of the information about a dissertation is entered correctly. • marc 21 bibliographic format supports not only descriptions of theses and dissertations but also other published scientific results, such as a paper published in a journal, a monograph, a paper published in conference proceedings, etc. there are several examples where theses and dissertations are described using the marc 21 format in the bibliographic information systems of some universities.31 • dublin core (http://dublincore.org) is the most commonly used format for data exchange between different information systems, and data are exported in this format via the oaipmh protocol from the phd uns system into a network of digital libraries, such as darteurope, oatd, and nardus. the dublin core xml schema is available online at www.openarchives.org/oai/2.0/oai_dc.xsd. the representation in dublin core format can http://dublincore.org/ http://www.openarchives.org/oai/2.0/oai_dc.xsd information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 9 be used by librarians to check if the metadata will be correctly exported to the previously mentioned aggregation systems. • electronic theses and dissertations metadata standard (etd-ms) (www.ndltd.org/standards/ metadata) is an extension of the dublin core format with new features/properties. the standard defines a set of metadata that is used to describe a master’s thesis or a doctoral dissertation. the metadata of this standard describe the author, his/her paper, and the context in which this paper has been created in a way that will be useful not only to the researcher, but also to the librarian and/or the technical staff in charge of maintaining the paper in electronic form. this format is used within the ndltd worldwide network of digital theses and dissertations and in this format the data is exported via the oai-pmh protocol from the phd uns system to this network. the xml schema of the etd-ms format is available online at www.ndltd.org/ standards/metadata/etdms/1.0/etdms.xsd. the representation in the etd-ms format can be used by librarians to check if the metadata will be correctly exported to the ndltd network (http://union.ndltd.org/). visual representation a word cloud is a visual representation of textual content, with the importance of each word indicated with a different font size and/or color. word clouds are often used in many digital libraries to represent textual content.32 as previously written, the word cloud is used in different environments and is a popular way to represent web results by summarizing the content of documents and other sources of information. we adopted a word cloud approach for visual representation of the user search results in the phd uns library. various tools for generating word clouds are available, such as the tool offered by jin.33 based on the characteristics of available tools, we decided to implement the kumo library available in the java programming language (https://github.com/kennycason/kumo) that allows easier integration within the phd uns digital library. implementation details this section presents the implementation of the textual and visual search results representation, as well as the implementation of the search results personalization. textual results representation based on the analysis presented in the previous section, we decided to implement the following functionality in order to enhance the phd uns digital library: a structured representation for users outside the academic community, a representation in the form of references for scholars , and a representation of bibliographic and library formats for librarians in charge of data in the phd uns digital library. reference representation. figure 2 depicts the architecture of the module for generating phd dissertations’ representations in the form of references for scholars. http://www.ndltd.org/standards/%20metadata

representation. the model of the reference generator component is shown as the class diagram in figure 3. this component can be used to generate textual representation to all publications from the data model component (figure 4) in the chosen reference style (freemarker template—see listing 1). the central class is templaterunner which includes the necessary operations to generate reports. the templateholder represents the template container and has operations for adding new templates and selecting template for generating report. the template class is the model of the template for one reference style and one publication type. the component architecture described in the class diagram of figure 3 is independent of the number of templates, whereas adding a new template to the component requires creating a new instance of the template class. as similarly performed in the cris uns system, the implementation of these instances of the template class is done in freemarker that does not require the recompilation of the source code. freemarker template reference generator data model phd uns database reference representation information technology and libraries march 2021

dissertation with the help of html markup. when storing a dissertation in a database, html representation is generated and stored in lucene indexes for faster representation of search results. bibliographic formats representation. after analyzing the bibliographic and library formats (see the methodology section above) we concluded that we should implement the search results representation in marc21, dublin core, and etd-ms bibliographic formats for the needs of librarians who are in charge of entering data in the phd uns library. the representation of these formats is implemented in a

representation is realized using a word cloud to represent the content of a dissertation. word cloud generator component. the word cloud generator component forms a new part of the phd uns digital library. the aim of this new component is to present the user search results in a word cloud representation (see fig. 7). information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 15 figure 7. word cloud generator steps. the word cloud component was implemented in java. the component accepts a pdf file as input and generates an image (png file) as output. the tool uses as input the pdf file of the dissertation ; it then parses the textual content of the file and performs a preprocessing of the text. the result of the preprocessing is a list of pairs containing the original version of each word from the text and its stem. the details of the tool utilized for this preprocessing step can also be found in the existing publication.34 the tool then calculates the top frequencies of words in the text, generates the word cloud, and creates an image file. as aforementioned, for implementation purposes, the kumo library was used (https://github.com/kennycason/kumo). kumo is an open source software that carries the mit license. the source code has been extended to accommodate the needs of the phd uns digital library. https://github.com/kennycason/kumo information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 16 integration to the phd uns system. the word cloud generator component described in the previous section has been integrated into the phd uns digital library application and was put into operation in april 2017, although some necessary adaptations have been performed since then and have all been integrated as well. taking into account that the word cloud generator is lengthy and creates a computationally intensive process, it is invoked in the indexing phase and the generated image is stored as supplementary material to a phd dissertation in the server file system. figure 8 presents a unified modeling language (uml) activity diagram which describes the process of adding a new dissertation to the phd uns digital library. the activity “generate word cloud image” is highlighted in red and represents invoking the execution of the word cloud component. moreover, the activity “create lucene index” includes the same steps for text preprocessing as the steps described in the word cloud generator component (see fig. 7). figure 8. adding a new dissertation into the phd uns system. the search results representation in the form of a word cloud is enabled via the user interface page for

implementation related to personalization of the search results representation. the user can select the desired style of representation, and the representation history of the results is recorded in order to personalize the results representation and customize the user’s profile and information needs. the initial search results representation style for users who search for dissertations in the phd uns system for the very first time is the random selection of one of the two options: • result representation in a textual format • result representation as word cloud images after analyzing the logs from changing the results representation (see next section), this random selection could be replaced with a choice that depends on the context: queries, devices, types of searches, etc. the parts of the page which represent how the results are presented in the textual and word cloud representations are shown in figures 5 and 9, respectively. users can change the representation style from the page. in this way, users give feedback and indicate their preference for visualization of the results which is used in the future results representations for that user. information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 18 evaluation collecting user feedback if a digital library user changes the style of results representation, the relevant message about the change of the representation style together with the user metadata is recorded using the log4j. this process is shown in red in the activity diagram in figure 10. figure 10. the process of executing queries and giving feedback on the representation style. listing 2 is an example of a recorded message about the change of the representation style containing user metadata from the phd uns system. information, such as the time and territorial determinant of a web client, the agent used, and the representation style, are also recorded. the representation style is stored on the user browser in the form of cookies and represents the basic style for representing results in future searches of dissertations in the phd uns system. by analyzing the messages about the change of the representation style, we evaluate the results of our approach and examine how the users respond to the new style of representation. user phd uns define

is presented in this section. the results are represented using the kibana graph component of the elk stack. this component is used for visualization and data exploration, analysis of logs at specified time intervals, and realtime monitoring of applications. the word cloud generating component was put into operation in april 2017. log messages were analyzed from then until the end of 2019. in total, there were 17,474 analyzed messages about changing the style of search results representation. in these messages, the style was changed into a textual representation 16,032 times, while it was changed into a visual representation style in the form of a word cloud image 1,442 times. thus, most of the users of the phd uns system changed the representation style to textual rather than visual format. this tells us that the majority of users are more familiar with the textual style of representing search results in interaction with scientific systems. based on this analysis, it can be concluded that the random selection of the representation style of the results is not a good choice. we also analyzed the client devices used when changing representation style (textual and visual). computers were used considerably more frequently than mobile devices. devices with larger resolution screens are more suitable for presenting search results in different formats. distribution of the change in the representation style of the search results is similar for computers and mobile devices, and based on the device, we cannot conclude which representation style is more suitable for the user. the queries that were submitted by users before changing the style of representation were also analyzed; in other words, which of the queries and results representations initiated the change into the other style of representation. figure 11 and figure 12 show the most commonly executed queries before changing the style of representation into the textual and visual format, respectively. figure 11 shows the most commonly executed queries before changing into the textual style of representation. some of the queries shown on this figure represent the names of faculties of the university, such as • fakultet tehnick nauka (department of technical sciences) • filosofsk fakultet (department of philosophy) information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 21 figure 11. top queries before changing into the textual style the most commonly executed queries before changing into the visual representation style are shown in figure 12. some queries shown on this figure represent scientific fields, such as • doktor medicinskih nauka (doctor of medical science) • doktor geografskih nauka (doctor of geographical science) figure 12. top queries before changing into the visual representation style. based on figures 11 and 12, we can conclude that the queries users submitted before the change in the style of representing the results are of a general type, that is, they represent the queries in faculties or by scientific fields. these types of queries give long lists of results. for queries over longer periods of time where the representation of all dissertations defended in a certain period is required, users changed the representation style into visual. information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 22 the search mode used before the change into the textual style is shown in figure 13, while the search mode used before the change into the visual representation style is shown in figure 14. figure 13. search mode before changing into the textual style. figure 14. search mode before changing into the visual style. by analyzing figures 13 and 14, we conclude that most queries preceding the change of the representation style are set from the basic search mode (labeled basic on the figures), which is the default search mode. also, we notice that there is an increase in the percentage when changing into the visual style of the advanced search mode as compared to the basic search mode. this is in compliance with the analysis following figures 11 and 12, because in the advanced search mode we make queries for a time range that gives long lists of results. also, we notice that some users have changed the style of results representation several times , so it is assumed that different types of information require a different representation style. there has been no reduction or enlargement in the number of users since the introduction of the word cloud generating component, which indicates that the introduction of the new component has not affected the frequency of the system use significantly. conclusion this paper describes one improvement on user experience performed for the users of the phd uns digital library. this improvement was implemented through the personalization of the search results representation which was put into operation in april 2017. users of the phd uns digital library are using desktop and laptop computers considerably more than mobile devices (rq1). moreover, besides specific exploratory queries, the users are raising general queries by scientific fields, faculties, or in the time range. the phd uns digital library has three user groups: those from the academic community, those from outside the academic community, and librarians in charge of entering the dissertation data. for these three groups of users, the following textual search results representations (rq2) have been selected and implemented: harvard-style representation of the dissertation in the form of references for users from the academic community; html structured results representation for users outside the academic community; and marc 21, dublin core, etd-ms bibliographic records for the library users. for the visual representation, word cloud presentation based on the complete text from the pdf file of the information technology and libraries march 2021 personalization of search results | paskali, ivanovic, kapitsaki, ivanovic, surla, and surla 23 dissertation has been selected and implemented. it is possible to select the desired search results representation which initiates storing of the messages about the representation style of the results, client device used, time, etc. this message is joined with a preset query message to analyze the patterns of system usage and establish a correlation between the change of the representation style and the type of query, device, and search mode (rq3). based on the conducted analysis, we reached the following conclusions: • a significantly larger number of users of the phd uns system use the textual representation style rather than the visual representation. this tells us that a larger number of users is more familiar with the textual style of representing search results in interaction with scientific systems and that a random selection of the representation style of the results used since april 2017 was not a good choice for the first-time user. because of this observation, the initial selection of the representation style for the first-time user was changed to the textual search results representation (rq3). • some users changed the representation style of the results several times and it is assumed that different types of information require a different representation style. based on this, we can conclude that the possibility of personalizing the search results representation is a useful functionality that contributes to the improvement of the phd uns system and the user experience. • it has been established that the most frequent change of the visual results representation is after a query which shows all the dissertations from a certain time period taken from the advanced search mode, but there is no correlation between this change and the device being used. based on this, it can be concluded that in certain cases for queries which show long lists of results, it is more transparent to see the results in the visual mode (rq3). it is necessary to collect more data and carry out additional analysis, in order to be able to precisely establish the correlation or to precisely determine for which queries and for which types of users this applied to, so that the system could automatically change the style of representation in certain cases. directions for future research and application development include the following. it is planned to collect and analyze additional messages about the work of the digital library in order to further enhance the user experience. also, it is necessary to follow the trends of the results representation due to the change of standardized reference styles, bibliographic formats, technologies and hardware devices, and it is further necessary to coordinate the results representation with these trends. differences between the behavior of the different user groups will also be examined further. endnotes 1 j. brophy and d. bawden, “is google enough? comparison of an

 findings  demonstrate  the  importance  of  strategy  and  interactivity  via  social  media  for   generating  new  connections  with  library  users.  details  of  this  research  include  successful  guidelines   for  building  community  and  developing  engagement  online  with  social  media.  by  applying   intentional  social  media  practices,  the  researchers’  twitter  user  community  grew  100  percent  in  one   year,  with  a  corresponding  275  percent  increase  in  user  interactions.  using  a  community  analysis   approach,  this  research  demonstrates  that  the  principles  of  personality  and  interactivity  can  lead  to   community  formation  for  targeted  user  groups.  discussion  includes  the  strategies  and  research   approaches  that  were  employed  to  build,  study,  and  understand  user  community,  including  user-­‐type   analysis  and  action-­‐object  mapping.  from  this  research  a  picture  of  the  library  as  a  member  of  an   active  academic  community  comes  into  focus.     introduction   this  paper  describes  an  academic  library’s  approach  to  building  community  through  twitter.   much  of  the  literature  offers  guidance  to  libraries  on  approaches  to  using  social  media  as  a   marketing  tool.  the  research  presented  here  reframes  that  conversation  to  explore  the  role  of   social  media  as  it  relates  to  building  community.  the  researchers’  university  library  formed  a   social  media  group  and  implemented  a  social  media  guide  to  bring  an  intentional,  personality-­‐rich,   and  interaction-­‐driven  approach  to  its  social  media  activity.  quantitative  analyses  reveal  a   significant  shift  and  increase  in  twitter  follower  population  and  interactions,  and  suggest   promising  opportunities  for  social  media  to  strengthen  the  library’s  ties  with  academic   communities.     literature  review   research  in  libraries  has  long  brought  a  critical  analysis  to  the  value,  purpose,  and  practical  usage   of  social  media.  glazer  asked  of  library  facebook  usage,  “clever  outreach  or  costly  diversion?”1   three  years  later,  glazer  presented  a  more  developed  perspective  on  facebook  metrics  and  the   nature  of  online  engagement,  but  social  media  was  still  described  as  “puzzling  and  poorly   defined.”2  vucovich  et  al.  furthermore  notes  that  “the  usefulness  of  [social  networking  tools]  has   often  proven  elusive,  and  evaluating  their  impact  is  even  harder  to  grasp  in  library  settings.”3     scott  w.  h.  young  (swyoung@montana.edu)  is  digital  initiatives  librarian  and     doralyn  rossmann  (doralyn@montana.edu)  is  head  of  collection  development,                 montana  state  university  library,  bozeman.     building  library  community  through  social  media  |  young  and  rossmann   21   li  and  li  similarly  observe  that  there  “seems  to  be  some  confusion  regarding  what  exactly  social   media  is.”4  social  media  has  been  experimented  with  and  identified  variously  as  a  tool  for   enhancing  the  image  of  libraries,5  as  a  digital  listening  post,6  or  as  an  intelligence  gathering  tool.7   with  such  a  variety  of  perspectives  and  approaches,  the  discussion  around  social  media  in   libraries  has  been  somewhat  disjointed.     if  there  is  a  common  thread  through  library  social  media  research,  however,  it  ties  together  the   broadcast-­‐based  promotion  and  marketing  of  library  resources  and  services,  what  li  calls  “the   most  notable  achievement  of  many  libraries  that  have  adopted  social  media.”8  this  particularly   common  approach  has  been  thoroughly  examined.9,10,11,12,13,14,15  in  evaluating  the  use  of  facebook   at  western  michigan  university’s  waldo  library,  sachs,  eckel,  and  langan  found  that  promotion   and  marketing  was  the  only  “truly  successful”  use  for  social  media.16  a  survey  of  estonian   librarians  revealed  that  facebook  “is  being  used  mainly  for  announcements;  it  is  reduplicating   libraries’  web  site[s].  interestingly  librarians  don’t  feel  a  reason  to  change  anything  or  to  do   something  differently.”17  with  this  widespread  approach  to  social  media,  much  of  the  library   literature  is  predominated  by  exploratory  descriptions  of  current  usage  and  implementation   methods  under  the  banner  of  promoting  resources  by  meeting  users  where  they  are  on  social   media.18,19,20,21,22,23,24,25,26,27  this  research  is  effective  at  describing  how  social  media  is  used,  but  it   often  does  not  extend  the  discussion  to  address  the  more  difficult  and  valuable  question  of  why   social  media  is  used.     the  literature  of  library  science  has  not  yet  developed  a  significant  body  of  research  around  the   practice  of  social  media  beyond  the  broadcast-­‐driven,  how-­‐to  focus  on  marketing,  promotion,  and   public-­‐relations  announcements.  this  deficiency  was  recognized  by  saw,  who  studied  social   networking  preferences  of  international  and  domestic  australian  students,  concluding  “to  date,   the  majority  of  libraries  that  use  social  networking  have  used  it  as  a  marketing  and  promotional   medium  to  push  out  information  and  announcements.  our  survey  results  strongly  suggest  that   libraries  need  to  further  exploit  the  strengths  of  different  social  networking  sites.”28  from  this   strong  emphasis  on  marketing  and  best  practices  emerges  an  opportunity  to  examine  social  media   from  another  perspective—community  building—which  may  represent  an  untapped  strength  of   social  networking  sites  for  libraries.     while  research  in  library  and  information  science  has  predominantly  developed  around  social   media  as  marketing  resource,  a  small  subset  has  begun  to  investigate  the  community-­‐building   capabilities  of  social  media.29,30,31,32  by  making  users  feel  connected  to  a  community  and   increasing  their  knowledge  of  other  members,  “sites  such  as  facebook  can  foster  norms  of   reciprocity  and  trust  and,  therefore,  create  opportunities  for  collective  action.”33  lee,  yen,  and   hsiao  studied  the  value  of  interaction  and  information  sharing  on  social  media:  “a  sense  of   belonging  is  achieved  when  a  friend  replies  to  or  ‘likes’  a  post  on  facebook.”34  lee  found  that   facebook  users  perceived  real-­‐world  social  value  from  shared  trust  and  shared  vision  developed   and  expressed  through  information-­‐sharing  on  social  media.  research  from  oh,  ozkaya,  and     information  technology  and  libraries  |  march  2015      22   larose  indicated  that  users  who  engaged  in  a  certain  quality  of  social  media  interactivity   perceived  an  enhanced  sense  of  community  and  life  satisfaction.35   broader  discussion  of  social  media  as  a  tool  for  community-­‐building  has  been  advanced  within  the   context  of  political  activity,  where  social  media  is  identified  as  a  method  for  organizing  civic  action   and  revolutionary  protests.36,37,38  related  research  focuses  on  the  online  social  connections  and   “virtual  communities”  developed  around  common  interests  such  as  religion,39  health,40   education,41  social  interests  and  norms,42  politics,43  web-­‐video  sharing,44  and  reading.45  in  these   analyses,  social  media  is  framed  as  an  online  instrument  utilized  to  draw  together  offline  persons.   hofer  notes  that  communities  formed  online  through  social  media  activity  can  generate  a  sense  of   “online  bonding  social  capital.”46  further  marking  the  online/offline  boundary,  research  from   grieve  et  al.  investigates  the  value  of  social  connectedness  in  online  contexts,  suggesting  that   social  connectedness  on  facebook  “is  a  distinct  construct  from  face-­‐to-­‐face  social   connectedness.”47  grieve  et  al.  acknowledges  that  the  research  design  was  predicated  on  the   assumptive  existence  of  an  online/offline  divide,  noting  “it  is  possible  that  such  a  separation  does   not  exist.”48   around  this  online/offline  separation  has  developed  “digital  dualism,”  a  theoretical  approach  that   interrogates  the  false  boundaries  and  contrasts  between  an  online  world  as  distinct  from  an   offline  world.49,50  sociologist  zeynep  tufekci  expressed  this  concisely:  “in  fact,  the  internet  is  not  a   world;  it’s  part  of  the  world.”51  a  central  characteristic  of  community-­‐building  through  social   media  is  that  the  “online”  experience  is  so  connected  and  interwoven  with  the  “offline”  experience   as  to  create  a  single  seamless  experience.  this  concept  is  related  to  a  foundational  study  from   ellison,  steinfield,  and  lampe,  who  identified  facebook  as  a  valuable  subject  of  research  because   of  its  “heavy  usage  patterns  and  technological  capacities  that  bridge  online  and  offline   connections.”52  they  conclude,  “online  social  network  sites  may  play  a  role  different  from  that   described  in  early  literature  on  virtual  communities.  online  interactions  do  not  necessarily   remove  people  from  their  offline  world  but  may  indeed  be  used  to  support  relationships.”53   this  paper  builds  on  existing  online  community  research  while  drawing  on  the  critical  theory  of   “digital  dualism”  to  argue  that  communities  built  through  social  media  do  not  reside  in  a  separate   “online”  space,  but  rather  are  one  element  of  a  much  more  significant  and  valuable  form  of  holistic   connectedness.  our  research  represents  a  further  step  in  shifting  the  focus  of  library  social  media   research  and  practice  from  marketing  to  community  building,  recasting  library-­‐led  social  media  as   a  tool  that  enables  users  to  join  together  and  share  in  the  commonalities  of  research,  learning,  and   the  university  community.  as  library  social  media  practice  advances  within  the  framework  of   community,  it  moves  from  a  one-­‐dimensional  online  broadcast  platform  to  a  multidimensional   socially  connected  space  that  creates  value  for  both  the  library  and  library  users.   method     in  may  2012,  montana  state  university  library  convened  a  social  media  group  (smg)  to  guide  our     building  library  community  through  social  media  |  young  and  rossmann   23   social  media  activity.  the  formation  of  smg  marked  an  important  shift  in  our  social  media  activity   and  was  crucial  in  building  a  strategic  and  programmatic  focus  around  social  media.  this  internal   committee,  comprising  three  librarians  and  one  library  staff  member,  aimed  to  build  a  community   of  student  participants  around  the  twitter  platform.  smg  then  created  a  social  media  guide  to   provide  structure  for  our  social  media  program.  this  guide  outlines  eight  principal  components  of   social  media  activity  (see  table  1).     social  media  guide  component   twitter  focus   audience  focus   undergraduate  and  graduate  students   goals   connect  with  students  and  build  community   values   availability,  care,  scholarship   activity  focus   information

 featured  automated  posts  that  lacked  a  sense  of   presence  and  personality.  after  the  formation  of  smg,  our  twitter  activity  featured  hand-­‐crafted   posts  that  possessed  both  presence  and  personality.  to  measure  the  effectiveness  of  our  social   media  program,  we  divided  our  twitter  activity  into  two  categories  based  on  the  may  2012  date  of   smg’s  formation:  phase  1  (pre-­‐smg)  and  phase  2  (post-­‐smg).  phase  1  user  data  included   followers  1–514,  those  users  who  followed  the  library  between  november  2008,  when  the  library   joined  twitter,  and  april  2012,  the  last  month  before  the  library  formed  smg.  phase  2  included   followers  515–937,  those  users  who  followed  the  library  between  may  2012,  when  the  library   formed  smg,  and  august  2013,  the  end  date  of  our  research  period.  using  corresponding  dates  to   our  user  analysis,  phase  1  tweet  data  included  the  library’s  tweets  1–329,  which  were  posted   between  november  2008  and  april  2012,  and  phase  2  included  the  library’s  tweets  330–998,   which  were  posted  between  may  2012  and  august  2013  (table  2).  for  the  purposes  of  this   research,  phase  1  and  phase  2  users  and  tweets  were  evaluated  as  distinct  categories  so  that  all   corresponding  tweets,  followers,  and  interactions  could  be  compared  in  relation  to  the  formation   date  of  smg.  within  twitter,  “followers”  are  members  of  the  user  community,  “tweets”  are     information  technology  and  libraries  |  march  2015      24   messages  to  the  community,  and  “interactions”  are  the  user  behaviors  of  favoriting,  retweeting,  or   replying.  favorites  are  most  commonly  employed  when  users  like  a  tweet.  favoriting  a  tweet  can   indicate  approval,  for  instance.  a  user  may  also  share  another  user’s  tweet  with  their  own   followers  by  “retweeting.”         followers   tweets   duration   phase  1   1–514   1–329   nov.  2008–april  2012   phase  2   515–937   330–998   may  2012–august  2013   table  2.  comparison  of  phase  1  and  2  twitter  activity   we  employed  three  approaches  for  evaluating  our  twitter  activity:  user  type  analysis,  action-­‐ object  mapping,  and  interaction  analysis.  user  type  analysis  aims  to  understand  our  community   from  a  broad  perspective  by  creating  categories  of  users  following  the  library’s  twitter  account.   after  reviewing  the  accounts  of  each  member  of  our  user  community,  we  collected  them  into  one   of  the  following  nine  groups:  alumni,  business,  community  member,  faculty,  library,  librarian,   other,  spam,  and  student.  categorization  was  based  on  a  manual  review  of  information  found  from   each  user’s  biographical  profile,  tweet  content,  account  name,  and  a  comparison  against  campus   directories.     action-­‐object  mapping  is  a  quantitative  method  that  describes  the  relationship  between  the   performance  of  an  activity—the  action—in  relation  to  an  external  phenomenon—the  object.   action-­‐object  mapping  aims  to  describe  the  interaction  process  between  a  system  and  its   users.54,55,56,57  within  the  context  of  our  study,  the  system  is  twitter,  the  object  is  an  individual   tweet,  and  the  action  is  the  user  behavior  in  response  to  the  object,  i.e.,  a  user  marking  a  tweet  as  a   favorite,  retweeting  a  tweet,  or  replying  to  a  tweet.  we  collected  our  library’s  tweets  into  sixteen   object  categories:  blog  post,  book,  database,  event,  external  web  resource,  librarian,  library  space,   local  community,  other  libraries/universities,  photo  from  archive,  topics—libraries,  service,   students,  think  tank,  hortative,  and  workshop.   interaction  analysis  serves  as  an  extension  of  action-­‐object  mapping  and  aims  to  provide  further   details  about  the  level  of  interaction  between  a  system  and  its  users.  for  this  study  we  created  an   associated  metric,  “interaction  rate,”  that  measures  the  rate  by  which  each  object  category   received  an  action.  within  the  context  of  our  study,  we  have  treated  the  “action”  of  action-­‐object   mapping  and  the  “interaction”  of  twitter  as  equivalents.  to  identify  the  interaction  rate,  we  used   the  following  formula:  “total  number  of  tweets  within  an  object  category”  divided  by  “number  of   tweets  within  an  object  category  that  received  an  action.”  interaction  rate  was  calculated  for  each   object  category  and  for  all  tweets  in  phase  1  and  in  phase  2.     building  library  community  through  social  media  |  young  and  rossmann   25     results   the  changes  in  approach  to  the  library’s  twitter  presence  through  smg  and  the  social  media   guide  are  evident  in  this  study’s  results  (figure  1).  an  analysis  of  user  types  in  phase  1  reveals  a   large  portion,  48  percent,  were  business  followers.  in  comparison,  the  business  percentage   decreased  to  30  percent  in  phase  2.  the  student  percentage  increased  from  6  percent  in  phase  1  to   28  percent  in  phase  2,  representing  a  366  percent  increase  in  student  users.  as  noted  earlier,  the   social  media  guide  component,  “audience  focus”  for  twitter  is  “undergraduate  and  graduate   students”  and  includes  the  “goal”  to  “connect  with  students  and  build  community”  (table  1).  the   increase  in  the  percentage  of  students  in  the  follower  population  and  the  decrease  in  the  business   percentage  of  the  population  suggest  progress  towards  this  goal.     figure  1.  comparison  of  twitter  users  by  type     the  object  categorization  for  phase  1  shows  a  heavily  skewed  distribution  of  tweets  in  certain   areas,  while  phase  2  has  a  more  even  and  targeted  distribution  reflecting  implementation  of  the   social  media  guide  components  (figure  2).  in  phase  1,  workshops  is  the  most  tweeted  category   with  of  36  percent  of  all  posts.  library  space  represents  18  percent  of  tweets  while  library  events   is  third  with  17  percent.  the  remaining  13  categories  range  from  5  percent  to  a  fraction  of  a   percent  of  tweets.  phase  2  shows  a  more  balanced  and  intentional  distribution  of  tweets  across  all   object  categories,  with  a  strong  focus  on  the  social  media  guide  “posting  category”  of  “student     information  technology  and  libraries  |  march  2015      26   life,”  which  accounted  for  25  percent  of  tweets.  library  space  consists  of  11  percent  of  tweets,  and   external  web  resource  composes  9  percent  of  tweets.  the  remaining  categories  range  from  8   percent  to  1  percent  of  tweets.       figure  2.  comparison  of  tweets  by  content  category   interaction  rates  were  low  in  most  object  categories  in  phase  1  (see  figure  3).  given  that  the  social   media  guide  has  an  “activity  focus”  of  “social  interaction,”  a  tweet  category  with  a  high  percentage   of  posting  and  a  low  interaction  rate  suggests  a  disconnect  between  tweet  posting  and  meeting   stated  goals.  for  example,  workshops  represented  a  large  percentage  (36  percent)  of  the  tweets   but  yielded  a  0  percent  interaction  rate.  library  space  was  18  percent  of  tweets  but  had  only  a  2   percent  interaction  rate.  eleven  of  the  16  categories  in  phase  1  had  no  associated  actions  and  thus   a  0  percent  interaction  rate.  the  interaction  rate  for  phase  1  was  12.5  percent.  in  essence,  our   action-­‐object  data  and  interaction  rate  data  shows  us  that  during  phase  1  we  created  content  most   frequently  about  topics  of  low  interest  to  our  community  while  we  tweeted  less  frequently  about   topics  of  high  interest  to  our  community.         building  library  community  through  social  media  |

 every  object  category  (figure  4,  figure  5),  especially  student  life  and  local  community.     figure  4.  interaction  rates,  phase  2   information  technology  and  libraries  |  march  2015      28     figure  5.  interaction  rate  comparison   the  local  community  category  of  tweets  had  the  highest  interaction  rate  at  68  percent.  the   student  life  category  had  the  second  highest  interaction  rate  at  62  percent.  only  2  of  the  16   categories  in  phase  2  had  no  associated  actions  and  thus  a  0  percent  interaction  rate.  the   interaction  rate  for  phase  2  was  46.8  percent,  which  represented  an  increase  of  275  percent  from   phase  1.  in  essence,  our  action-­‐object  data  and  interaction  rate  data  shows  us  that  during  phase  2   we  created  content  most  frequently  about  topics  of  higher  interest  to  our  community  while  we   tweeted  less  frequently  about  topics  of  low  interest  to  our  community.   discussion   this  research  suggests  a  strong  community-­‐building  capability  of  social  media  at  our  academic   library.  the  shift  in  user  types  from  phase  1  to  phase  2,  notably  the  increase  in  student  twitter   followers,  indicates  that  the  shape  of  our  twitter  community  was  directly  affected  by  our  social   media  program.  likewise,  the  marked  increase  in  interaction  rrate  between  phase  1  and  phase  2   suggests  the  effectiveness  of  our  programmatic  community-­‐focused  approach.     the  montana  state  university  library  social  media  program  was  fundamentally  formed  around  an   approach  described  by  glazer:  “be  interesting,  be  interested.”58  our  twitter  user  community  has   thrived  since  we  adopted  this  axiom.  we  have  interpreted  “interesting”  as  sharing  original     building  library  community  through  social  media  |  young  and  rossmann   29   personality-­‐rich  content  with  our  community  and  “interested”  as  regularly  interacting  with  and   responding  to  members  of  our  community.  the  twofold  theme  of  personality-­‐rich  content  and   interactivity-­‐based  behavior  has  allowed  us  to  shape  our  phase  2  user  community.   prior  to  the  formation  of  smg,  social  media  at  the  msu  library  was  a  rather  drab  affair.  the  library   twitter  account  during  that  time  was  characterized  by  automated  content,  low  responsiveness,  no   dedicated  personnel,  and  no  strategic  vision.  our  resulting  twitter  community  was  composed  of   mostly  businesses,  at  47  percent  of  followers,  with  students  representing  just  6  percent  of  our   followers.  the  resulting  interaction  rate  of  12.5  percent  reflects  the  broadcast-­‐driven  approach,   personality-­‐devoid  content,  and  disengaged  community  that  together  characterized  phase  1.   following  the  formation  of  smg,  the  library  twitter  account  benefitted  from  original  and  unique   content,  high  responsiveness,  dedicated  personnel,  and  a  strategic,  goal-­‐driven  vision.  our  phase  2   twitter  community  underwent  a  transformation,  with  business  representation  decreasing  to  30   percent  and  student  representation  increasing  to  28  percent.  the  resulting  interaction  rate  of  46.8   percent  reflects  our  refocused  community-­‐driven  program,  personality-­‐rich  content,  and  engaged   community  of  phase  2.     figure  6.  typical  phase  1  tweet   figure  6  illustrates  a  typical  phase  1  tweet.  the  object  category  for  this  tweet  is  database  and  it   yielded  no  actions.  the  announcement  of  a  new  database  trial  was  auto-­‐generated  from  our   library  blog,  a  common  method  for  sharing  content  during  phase  1.  this  tweet  is  problematic  for   community-­‐building  for  two  primary  reasons:  the  style  and  content  lacks  a  sense  and  personality   of  a  human  author  and  does  not  offer  compelling  opportunities  for  interaction.         information  technology  and  libraries  |  march  2015      30     figure  7.  typical  phase  2  tweet   figure  7  illustrates  a  typical  phase  2  tweet.  the  object  category  for  this  tweet  is  student  life  and  it   yielded  6  actions  (2  retweets  and  4  favorites).  the  content  relates  to  a  meaningful  and  current   event  for  our  target  student  user  community,  and  is  fashioned  in  such  a  way  as  to  invite   interaction  by  providing  a  strong  sense  of  relevancy  and  personality.  figure  8  further   demonstrates  the  community  effect  of  phase  2.  in  this  example  we  have  reminded  our  twitter   community  of  the  services  available  through  the  library,  and  one  student  user  has  replied.  during   our  phase  2  twitter  activity,  we  prioritized  responsiveness,  availability,  and  scholarship  with  the   goal  of  connecting  with  students  and  building  a  sense  of  community.  in  many  ways  the  series  of   tweets  shown  in  figure  8  encapsulates  our  social  media  program.  we  were  able  to  deliver   resources  to  this  student,  who  then  associates  these  interactions  with  a  sense  of  pride  in  the   university.  this  example  illustrates  the  overall  connectedness  afforded  by  social  media.  in   contacting  the  library  twitter  account,  this  user  asked  a  real-­‐world  research  question.  neither  his   inquiry  nor  our  response  was  located  strictly  within  an  online  world.  while  we  pointed  this  user   to  an  online  resource,  his  remarks  indicated  “offline”  feelings  of  satisfaction  with  the  interaction.   lee  and  oh  found  that  social  media  interactivity  and  information  sharing  can  create  a  shared   vision  that  leads  to  a  sense  of  community  belonging.59,60  by  creating  personality-­‐rich  content  that   invites  two-­‐way  interaction,  our  strategic  social  media  program  has  helped  form  a  holistic   community  of  users  around  our  twitter  activity.         building  library  community  through  social  media  |  young  and  rossmann   31     figure  8.  phase  2  example,  community  effect   currently  our  work  addresses  the  formation  of  community  through  social  media.  a  next  step  will   introduce  a  wider  scope  by  addressing  the  value  of  community  formed  through  social  media.   there  is  a  rich  area  of  study  around  the  relationship  between  social  media  activity,  perceived   sense  of  community  and  connectedness,  and  student  success.  61,62,63,64,65  further  research  along   this  line  will  allow  us  to  explore  whether  a  library-­‐led  social  media  community  can  serve  as  an  aid   in  undergraduate  academic  performance  and  graduation  rate.  continued  and  extended  analysis     information  technology  and  libraries  |  march  2015      32   will  allow  us  to  increase  the  granularity  of  results,  for  example  by  mapping  user  types  to  action-­‐ object  pairs  and  identifying  the  interaction  rate  for  particular  users  such  as  students  and  faculty.   conclusion   in  articulating  and  realizing  an  intentional  and  strategic  social  media  program,  we  have  generated   results  that  demonstrate  the  community-­‐building  capability  of  social  media.  over  the  course  of   one  year,  we  transformed  our  social  media  activity  from  personality-­‐devoid  one-­‐way  broadcasting   to  personality-­‐rich  two-­‐way  interacting.  the  research  that  followed  this  fundamental  shift   provided  new  information  about  our  users  that  enabled  us  to  tailor  our  twitter  activity  and  shape   our  community  around  a  target  population  of  undergraduate  students.  in  so  doing,  we  have   formed  a  community  that  has  shown  new  interest  in  social  media  content  published  by  the  library.   following  the  application  of  our  social  media  program,  our  student  user  community  grew  by  366   percent  and  the  rate  of  interaction  with  our  community  grew  by  275  percent.  our  research   demonstrates  the  value  of  social  media  as  a  community-­‐building  tool,  and  our  model  can  guide   social  media  in  libraries  toward  this  purpose.

program cory lampert and jason vaughan this paper discusses a dual approach of case study and research survey to investigate the complex factors in sustaining academic library digitization programs. the case study involves the background of the university of nevada, las vegas (unlv) libraries’ digitization program and elaborates on the authors’ efforts to gain staff support for this program. a related survey was administered to all association of research libraries (arl) members, seeking to collect baseline data on their digital collections, understand their respective administrative frameworks, and to gather feedback on both negative obstacles and positive inputs affecting their success. results from the survey, combined with the authors’ local experience, point to several potential success factors including staff skill sets, funding, and strategic planning. e stablishing a successful digitization program is a dialog and process already undertaken or currently underway at many academic libraries. in 2002, according to an institute of museum and library services report, “thirty-four percent of academic libraries reported digitization activities within the past 12 months.” nineteen percent expect to be involved in digitization work in the next twelve months, and forty-four percent beyond twelve months.1 more current statistics from a subsequent study in 2004 reflected that digitization work has both continued and expanded, with half of all academic libraries performing digitization activities.2 fifty-five percent of arl libraries responded to a survey informing part of the 2006 association of research libraries (arl) study managing digitization activities; of these, 97 percent of the respondents indicated engagement in digitization.3 the 2008 ithaka study key stakeholders in the digital transformation in higher education found that nearly 80 percent of large academic libraries either already have or plan to have digital repositories.4 with digitization becoming the norm in many institutions, the time is right to consider what factors contribute to the success and rapid growth of some library digitization programs while other institutions find digitization challenging to sustain. the evolution of digitization at the unlv libraries is doubtless a journey many institutions have undertaken. over the past couple of years, those responsible for such a program at the unlv libraries have had the opportunity to revitalize the program and help collaboratively address some key philosophical questions that had not been systematically asked before, let alone answered. associated with this was a concerted focus to engage other less involved staff. one goal was to help educate them on academic digitization programs. another goal was to provide an opportunity for input on key questions related to the programs’ strategic direction. as a subsequent action, the authors conducted a survey of other academic libraries to better understand what factors have contributed to their programs’ own success as well as challenges that have proven problematic. many questions asked of our library staff in the planning and reorganization process were asked in the survey of other academic libraries. while the unlv libraries have undertaken what is felt are the proper structural steps and have begun to author policies and procedures geared toward an efficient operation, the authors wanted to better understand the experiences, key players, and underlying philosophies of other institutional libraries as theses pertain to their own digitization program. the following article provides a brief context relating the background of the unlv libraries’ digitization program and elaborates on the authors’ efforts toward educating library colleagues and gaining staff buy-in for unlv’s digitization program—a process that countless other institutions have no doubt experienced, led, or suffered. the administered survey to arl members dealt with many topics similar to those that arose during the authors’ initial planning and later conversations with library staff, and as such, survey questions and responses are integrated in the following discussion. the authors administered a 26-question survey to the 123 members of the arl. the focus of this survey was different from the previously mentioned arl study managing digitization activities, though several of the questions overlapped to some degree. in addition to demographic or concrete factual types of questions, the unlv libraries digitization survey had several questions focused on perceptions—that is, staff support, administrative support, challenges, and benefits. areas of overlap with the earlier arl survey are mentioned in the appropriate context. though unlv isn’t a member of the arl, we consider ourselves a research library, and, regardless, it was a convenient way to provide some structure to the survey. survey responses were collected for a forty-five-day period from mid-june to late july, 2008. through visiting each and every arl library’s website, the authors identified the individuals that appeared to be the “leaders” of the arl digitization programs, with instructions to forward the message to a colleague if cory lampert (cory.lampert@unlv.edu) is digitization projects librarian and jason vaughan (jason.vaughan@unlv.edu) is director, library technologies, university of nevada las vegas. success factors and strategic planning | lampert and vaughan 117 they themselves had been incorrectly identified. this was very tricky, and revealed numerous program structures in place, differences between institutions in promoting their collections, and so on. the authors didn’t necessarily start with the presumption that all arl libraries even have a digitization program, but most (but not all) either seemed to have a formal organized digitization program with staffing, or at least had digitized and made available something, even if only a single collection. we e-mailed a survey announcement and a link to the survey to the targeted individuals, with a follow-up reminder a month later. responses were anonymous, and respondents were allowed to skip questions; thus the number of responses for the twenty-six questions making up the survey ranged from a low of thirty (24.4 percent) to a high of forty-four responses (35.8 percent). the average number of responses for each of the questions was 39.8, yielding an overall response rate of 32.4 percent. questions were of three types: multiple choice (select one answer), multiple choice (mark all that apply), and open text. in addition, some of the multiple choice questions allowed additional open text comments. survey responses appear in appendix a. n context of the unlv libraries’ digitization program “digital collection,” for the purpose of the unlv library digitization survey, was defined as a collection of library or archival materials converted to machine-readable format to provide electronic access or for preservation purposes; typically, digital collections are library-created digital copies of original materials presented online and organized to be easily searched. they may offer features such as: full text search, browsing, zooming and panning, side by side comparison of objects, and export for presentation and reuse. one question the survey asked was “what year do you feel your library published its first ‘major’ digital collection?” responses ranged from 1990 to 2007; the general average of all responses was 2001. the earlier arl study found 2000 as the year most respondents began digitization activities.5 mirroring this chronology, the unlv libraries has been active in designing digital projects and digitizing materials from library collections since the late 1990s. technical web design expertise was developed in the cataloging unit (later renamed bibliographic and metadata services), and some of the initial efforts were to create online galleries and exhibits of visual materials from special collections, such as the jeanne russell janish (1998) exhibit.6 subsequently, the unlv libraries purchased the contentdm digital collection management software, providing both back-end infrastructure and front-end presentation for digital collections. later, the first digitization project with search functionality was created in partnership with special collections and was funded by a unlv planning initiative award received in 1999. the early las vegas (2003) project focused on las vegas historical material and was designed to guide users to search, retrieve, and manipulate results using contentdm software to query a database.7 unlv’s development corresponds with regional developments in utah in 2001, when “the largest academic institutions in utah were just beginning to develop digital imaging projects.”8 data from the 2004 imls study showed that, in the twelve months prior to the study release in 2004, the majority of larger academic libraries had digitized between one and five hundred images for online presentation.9 in terms of staffing, digitization efforts occur in a wide variety of configurations, from large departments to solo librarians managing volunteers. for institutions with recognized digitization staff, great variations exist between institutions in terms of where in the organizational chart digitization staff are placed. boock and vondacek’s research revealed that, of departments involved in digitization, special collections, archives, technical services, and newly created digital library units are where digitization activities most commonly take place.10 a majority of respondents to the arl study indicated that some or all activities associated with digitization are distributed across various units in the library.11 in 2003, the unlv libraries created a formal department within the knowledge access management division—web and digitization services (wds)—initially comprising five staff focused on the development of the unlv libraries’ public website, the development of web-based applications and databases to manage and efficiently present information resources, and the digitization and online presentation of library materials unique to the unlv libraries’ collections and of potential interest to a wider audience. augmenting their efforts were individuals in other departments helping with metadata standards, content selection, and associated systems technical support. the unlv library digitization survey showed that the majority (78 percent) of libraries that responded have at least one full-time staff member whose central job responsibility is to support digitization activities. this should not imply the existence of a fully staffed digitization program; the 2006 imls study found that 74.1 percent of larger academic libraries described themselves as lacking in sufficiently skilled technology staff to accomplish technology-related activities.12 central to any digitization program should be some structure in terms of how projects are proposed and subsequently prioritized. to help guide the priorities 118 information technology and libraries | september 2009 of unlv’s infant wds department, a digital projects advisory committee was formed to help solicit and prioritize project ideas, and subsequently track the development of approved projects. this committee’s work could be judged as having mixed success partly because it met too infrequently, struggled with conflicting philosophical thoughts on digitization, and was confronted with the reality that staff that were needed to help bring approved ideas to fruition simply weren’t in place because of too many other library priorities drawing attention away from digitization. an evaluation of the lessons learned from these early years can be found in brad eden’s article.13 the unlv library digitization survey had several questions related to management and prioritization for digital projects and shows that despite the challenges of a committee-based decisionmaking structure, when a formal process is in place at all, 42.1 percent of survey respondents used a committee versus a single decision maker (23.7 percent) for determining to whom projects are proposed for production. a follow-up question asked “how are approved projects ultimately prioritized?” the most popular response (54.1 percent) indicated “by a committee for review by multiple people,” followed by “no formal process” (27 percent). “by a single decision maker” was selected by 18.9 percent of the respondents. the earlier arl study asked a somewhat related question: “who makes decisions about the allocation of staff support for digitization efforts? check all that apply.” out of seven possible responses, the three most popular were “head of centralized unit,” “digitization team/committee/working group,” and “other person”; the other person was most often in an administrative capacity, such as a dean, director, or department head.14 administrative support for a program was another variable the unlv library digitization survey investigated. the survey asked respondents to rate, on a scale of one to five, “how would you characterize current support for digitization by your library’s administration?” more than 40 percent of responses indicated “consistent support,” followed by 31 percent of respondents indicating “very strong support, top priority,” 14.3 percent ranking support as neutral, and 14.2 percent claiming “minimal support” or “very little support, or some resistance.” it was also clear from some of the other questions’ responses that the dean or director’s support (or lack thereof) can have dramatic effects on the digitization program. 2005 brought change to the unlv libraries in the form of a new dean. well-suited for the digitization program, she came from california, a state very heavily engaged and at the forefront of digitization within the library and larger academic environment. one of her initiatives was a retooling of the digitization program at the unlv libraries, and her enthusiasm reflects a growing awareness of administrators regarding the benefits of digitization. n reorganization, library staff engagement, and decision making in 2006, two new individuals joined unlv libraries’ web and digitization services department, the digitization projects librarian (filling a vacancy), and the web technical support manager (a new position). a bit later, the systems department (providing technical support for the web and digitization servers, among other things), and the wds department were combined into a single unit and renamed library technologies. collectively, these changes brought new and engaged staff into the digitization program and combined under one division many of the individuals responsible for digital collection creation and support. perhaps more subtlety, this arrangement also provided formal acknowledgement of the importance and desire of publishing digital collections. with the addition of new staff and a reorganization, a piece still missing was a resuscitation of library stakeholders to help solicit, prioritize, and manage the creation of digital collections and an overall vision guiding the program. while the technical expertise, knowledge of metadata and imaging standards, and deep-rooted knowledge of digitization programs and concepts existed within the library technologies staff, other knowledge didn’t—primarily in-depth knowledge of the unlv libraries’ special collections and a track record of deep engagement with college faculty and the educational curriculum. similar to other organizations, the unlv libraries had not only created a new unit, but was also poised to introduce cross-departmental project groups that would collaborate on digitization activities. in their study of arl and greater western library association (gwla) libraries, book and vondracek found that this was the most commonly used organizational structure.15 knowledge of the concepts of a digitization program and what is involved in digitizing and sustaining a collection was not widespread among other library colleagues. acknowledged, but not guaranteed up front for the unlv libraries, was the likely eventual reformation of a group of interested and engaged library stakeholders charged to solicit, prioritize, and provide oversight of the unlv libraries’ digitization program. for various reasons, the authors wanted to garner staff buy-in to the highest degree possible. apart from wanting less informed colleagues to understand the benefits of a digitization program, it was also likely that such colleagues would help solicit projects through their liaison work with programs of study across campus. one unlv library digitization survey question asked, “how would you characterize support for digitization in your library by the majority of those providing content for digitization projects?” “consistent support” was indicated by 65.9 percent of respondents; 15.9 percent indicated “very strong support, top priority,” 13.6 percent indicated neutrality, and 4.6 success factors and strategic planning | lampert and vaughan 119 percent indicated either minimal support or even some resistance. to help garner staff buy-in and set the stage for revitalizing the unlv libraries’ digitization efforts, we began laying the groundwork to educate and engage library staff in the benefits of a digitization program. this work included language successfully woven into the unlv libraries’ strategic plan and an authored white paper posing engaging questions to the larger library audience related to the strategic direction of the program. finally, we planned and executed two digitization workshops for library staff. n the strategic plan one unlv library digitization survey question asked, “is the digitization program or digitization activities referenced in your library’s strategic plan?” a total of 63.4 percent indicated yes, with an additional 22 percent indicating no specific references, but rather implied references. only 7.3 percent indicated that the digitization program was not referenced in any manner in the strategic plan, while, surprisingly, 3 responses (7.3 percent) indicated that their library doesn’t have a strategic plan. the unlv libraries’ strategic plan is an important document authored with wide feedback from library staff, and it exemplifies the participatory decision-making process in place in the library. the current iteration of the strategic plan covers 2007–9 and includes various goals with supporting strategies and action items.16 in addition, all action items have associated assessment metrics and library staff responsible for championing the action items. departmental annual reports explicitly reference progress toward strategic plan goals. as such, if goals related to the digitization program appear in the strategic plan, that’s a clear indication, to some degree, of staff buy-in in acknowledging the significance of the digitization program. fortunately, digitization efforts figure prominently in several goals, strategies, and action items, including the following: n increasingly provide access to digital collections and services to support instruction, research, and outreach while improving access to the unlv libraries’ print and media collections. n provide greater access to digital collections while continuing to build and improve access to collections in all formats to meet the research and teaching needs of the university. identify collections to digitize that are unique to unlv and that have a regional, national, and international research interest. create digital projects utilizing and linking collections. develop and adapt metadata and scanning standards that conform to national standards for all formats. provide content and metadata for regional and national digital projects. continue to develop expertise in the creation and management of digital collections and information. collaborate with faculty, students, and others outside the library in developing and presenting digital collections. n be a comprehensive resource for the documentation, investigation, and interpretation of the complex realities of the las vegas metropolitan area and provide an international focal point for the study of las vegas as a unique urban and cultural phenomenon. facilitate real and digital access to materials and information that document the historical, cultural, social, and environmental setting of las vegas and its region by identifying, collecting, preserving, and managing information and materials in all formats. identify unique collections that strengthen current collections of national and international significance in urban development and design, gaming, entertainment, and architecture. develop new access tools and enhance the use of current bibliographic and metadata utilities to provide access to physical and digital collections. develop web-based digital projects and exhibits based upon the collections. an associated capital campaign case statement associated with the strategic plan lists several gift opportunities that would benefit various aspects of the unlv libraries; several of these include gift ideas related to the digitization of materials. n the white paper another important step in laying the groundwork for the digitization program was a comprehensive white paper authored by the recently hired digitization projects librarian. the finished paper was originally given to the dean of libraries and thereafter to the administrative cabinet, and eventually distributed to all library staff. the outline of this white paper is provided as appendix b. the purpose of the white paper was multifaceted. after a brief historical context, the white paper addressed perhaps the single most important aspect of a digitization program—program planning—developing the strategic goals of the program, selecting and prioritizing projects though a formal decision-making process, and managing initiatives from idea to reality through efficient project teams. this first topic addressing the core values of the program had a strong educational purpose for the entire library staff—the ultimate audience of the paper. as part of its educational goal, the white paper enumerated the various strengths of digitization and why an institution 120 information technology and libraries | september 2009 would want to sustain a digitization program (providing greater worldwide access to unique materials, promoting and supporting education and learning when integrated with the curriculum, etc.). it defined distinctions between an ephemeral digital exhibit and a long-term published and maintained collection. it discussed the various components of a digital collection—images, multimedia, metadata, indexing, thematic presentation (and the preference to be unbiased), integration with other digital collections and the library website, etc. it posited important questions on sustenance and assessment, and defined concepts such as refreshing of data and migration of data to help set the stage for future philosophical discussions. given the myriad reasons one might want to publish a digital collection, checked by the reality that all the reasons and advantages may not be realized or given equal importance, the white paper listed several scenarios and asked if each scenario was a strong underlying goal for our program—in short, true or false: n “the libraries are interested in digitizing select unique items held in our collection and providing access to these items in new formats.” n “the libraries are interested in digitizing whole runs of an information resource for access in new formats.” n “the libraries should actively pursue funding to support major digitization initiatives.” n “the libraries should take advantage of the unique publicity, promotion, and marketing opportunities afforded by a digital project/program.” continuing with a purpose of defining boundaries of the new program, the paper asked questions related to audience, required skill sets, and resources. the second primary topic introduced the selection and prioritization of the items and ideas suggested for digitization. it posed questions related to content criteria (why does this idea warrant consideration? would complex or unique metadata be required from a subject specialist?) and listed various potential evaluative measures of project ideas (should we do this if another library is already doing a very similar project?). technical criteria considerations were enumerated, touching on interoperability of collections in different formats, technical infrastructure considerations, and so on. multiple simultaneous ideas beg for prioritization, and the white paper proposed a formal review process and the library staff and skill sets that would help make such a process successful. the third primary topic focused on the details of carrying an approved idea to reality, and strengthened the educational purpose of the white paper. it described the general planning steps for an approved project and included a list of typical steps involved with most digital projects—scanning; creating metadata, indexes, and controlled vocabulary; coding and designing the web interface; loading records into unlv libraries’ contentdm system; publicizing the launch of the project; and assessing the project after completion. one unlv library digitization survey question was related to thirteen such skills the unlv libraries identified as critical for a successful digitization program. the question asked respondents to rate skill levels possessed by personnel at their library, based on a five-point scale (from one to five: “no expertise,” “very limited expertise,” “working knowledge/enough to get by,” “advanced knowledge,” and “tremendous expertise”). neither “no expertise” nor “very limited expertise” garnered the highest number of responses for any of the skills. the overall rating average of all thirteen skills was 3.79 out of 5. the skills with the highest rating averages were “metadata creation/cataloging” 4.4 and “digital imaging/document scanning/post image processing/photography” with 4.27. the skills with the lowest rating averages were “marketing and promotion” with 2.95 followed by “multimedia formats” with 3.33. the unlv libraries’ white paper contained several appendixes that likely provided some of the richest content of the white paper. with the educational thrust completed, the appendixes drew a roadmap of “where do we want to go from here?” this roadmap suggested the revitalization of an overarching digital projects advisory committee, potential members of the committee, and functions of the committee. the committee would be responsible for soliciting and prioritizing ideas and tracking the progress of approved ideas to publication. the appendixes also proposed project teams (which would exist for each project), likely members of the project teams, and the functions of the project team to complete day-to-day digitization activities. the liaison between the digital projects advisory committee and the project team would be the digitization projects librarian, who would always serve on both. the last page of the white paper provided an illustration highlighting the various steps proposed in the lifecycle of a digital project—from concept to reality. n digitization workshops several months after the white paper had been shared, the next step in restructuring the program and building momentum was sponsoring two forums on digitization. the first one occurred in november 2006 and included two speakers brought in for the event, roy tennant (formerly user services architect with the california digital library and now with oclc) and ann lally (head of the digital initiatives program at the university of washington libraries). this session consisted of a success factors and strategic planning | lampert and vaughan 121 two-hour presentation and q&a to which all library staff were invited, followed by two breakout sessions. all three sessions were moderated by the digitization projects librarian. questions from these sessions are provided in appendix c. the breakout sessions were each targeted to specific departments in the unlv libraries. the first focused on providing access to digital collections (definitions of digital libraries, standards, designing useful metadata, accessibility and interoperability, etc.). the second focused on components of a well-built digital library (goals of a digitization program, content selection criteria, collaboration, evaluation and assessment, etc.). colleagues from other libraries in nevada were invited, and the forum was well attended and highly praised. the sessions were recorded and later made available on dvd for library staff unable to attend. this initial forum accomplished two important goals. first, it was an allstaff meeting offering a chance to meet, explore ideas, and learn from two well-known experts in the field. second, it offered a more intimate chance to talk about the technical and philosophical aspects of a digitization program for those individuals in the unlv libraries associated with such tasks. as a momentum-building opportunity for the digitization program, the forum was successful. the second workshop occurred in april 2007. to gain initial feedback on several digitization questions and to help focus this second workshop, we sent out a survey to several dozen library staff—those that would likely play some role at some point in the digitization program. the survey contained questions focused on several thematic areas: defining digital libraries, boundaries to the digitization program, users and audience, digital project design, and potential projects and ideas. it contained thirteen questions consisting of open-ended response questions, questions where the respondent ranked items on a five-point scale, and “select all that apply”–type questions. we distributed the survey to invitees to the second workshop, approximately three dozen individuals; of those, eighteen (about 50 percent) responded to most of the questions. the survey was closely tied to the white paper and meant to gauge early opinions on some of the questions posed by that paper. whereas the first workshop included some open q&a, the second session was structured as a hands-on workshop to answer some of the digitization questions and to illustrate the complexity of prioritizing projects. the second workshop began with a status update on the retooling of the unlv libraries’ digitization program. this was followed by an educational component that focused on a diagram that detailed the workflow of a typical digitization project and who was involved and that emphasized the fact that there is a lot of planning and effort needed to bring an idea to reality. in addition, we discussed project types and how digital projects can vary widely in scope, content, and purpose. finally, we shared general results from the aforementioned survey to help set the stage for the structured hands-on exercises. the outline for this second workshop is provided in appendix d. one question of the unlv library digitization survey asked, “on a scale of 1 to 5, how important are each of the factors in weighing whether to proceed with a proposal for a new digital collection project, or enhancement of an existing project?” eight factors were listed, and the fivepoint scale was used (from one to five: “not important,” “less important,” “neutral,” “important,” and “vitally important”). the average rating for all eight factors was 3.66. the two most important factors were “collection includes unique items” (4.49 average rating) and “collection includes items for which there is a preservation concern or to make fragile items more accessible to the public” (3.95 average rating). the factors with the lowest average ratings were “collection includes integration of various media into a themed presentation” (2.54 average rating) followed by “collection involves a whole run of an information resource (i.e., such as an entire manuscript, newspaper run, etc.” (3.39 average rating). the earlier arl survey asked a somewhat related question, “what is/has been the purpose of these digitization efforts? check all that apply.” of the six possible responses (which differed somewhat from those in the unlv library digitization survey), the most frequent responses were “improved access to library collections,” “support for research,” and “preservation.”17 the earlier survey also asked the question, “what are the criteria for selecting material to be digitized? check all that apply.” the most frequent responses were “subject matter,” “material is part of a collection being digitized,” and “rarity or uniqueness of the item(s).”18 the first exercise of the second digitization workshop focused on digital collection brainstorming. the authors provided a list of ten project examples and asked each of the six tables (with four colleagues each) to prioritize the ideas. afterward, a speaker from each table presented the prioritizations and defended their rankings. this exercise successfully illustrated to peers in attendance that different groups of people have different ideas about what’s important and what constitutes prime materials for digitization. the rankings from the varying tables were quite divergent. a related question asked of the arl libraries in the unlv library digitization survey was “from where have ideas originated for existing, published digital collection at your library?” and offered six choices. respondents could mark multiple items. the most chosen answer (92.7 percent) was “special collections, archives, or library with a specialized collection or focus.” the least chosen answer (51.2 percent) was “an external donor, friend of the library, community user, etc.” for the second part of the workshop exercise, each table came up with their own digital collection ideas, defined the audience and content of the proposal, and defended and 122 information technology and libraries | september 2009 explained why they thought these were good proposals. fourteen unique and varied ideas were proposed, most of which were tightly focused on las vegas and nevada, such as “history of las vegas,” “unlv yearbooks,” “las vegas gambling and gamblers,” and “african american entertainers in las vegas.” other proposals were less tied to the area, such as a “botany collection,” “movie posters,” “children’s literature,” “architecture,” and “federal land management.” this exercise successfully showed that ideas for digital collections stretch across a broad spectrum, as broad as the individual brainchilden themselves. finally, in the last digitization workshop exercise, each table came up with specialties, roles, and skills of candidates who could potentially serve on the proposed committee, and defended their rationale—in other words, committee success factors. this exercise generated nineteen skills seen as beneficial by one or more of the group tables. at the end of the workshop, we asked if others had alternate ideas to the proposed committee. none surfaced, and the audience thought such a committee should be reestablished. this second workshop concluded with a brief discussion on next steps—drafting a charge for the committee, choosing members, and a plug for the expectation of subject liaisons working with their respective areas to help better identify opportunities for collaboration on digital projects across campus. n toward the future digital projects currently maintained by the unlv libraries include both static web exhibits in the tradition of unlv’s first digitization efforts, as well as several searchable contentdm–powered collections. the unlv libraries have also sought to continue collaborative efforts, participating as project partners for the western waters digital library (phase 1) and continuing in a regional collaboration as a hosting partner in the mountain west digital library. partnerships were shown in the unlv library digitization survey to garner increased buy-in for projects, with one respondent commenting that faculty partnerships had been “the biggest factor for success of a digital library project.” institutional priorities at unlv libraries reflect another respondent’s comment regarding “interesting archival collections” as a success factor. one recently launched unlv collection is the showgirls collection (2006), focused on a themed collection of historical material about las vegas entertainment history.19 another recently launched collection, the nevada test site oral history project (2008), recounts the memories of those affiliated with and affected by the nevada test site during the era of cold war nuclear testing and includes searchable transcripts, selected audio and video clips, and scanned photographs and images.20 with general library approval, the restructured digitization projects advisory committee was established in july 2007 with six members drawn from library technologies, special collections, the subject specialists, and at large. the advisory committee has drafted and gained approval for several key documents to help govern the committee’s future work. this includes a collection development policy for digitization projects and a project proposal form to be completed by the individual or group proposing an idea for a digital collection. at the time of writing, the committee is just now at the point of advertising the project proposal form and process, and time will tell how successful these documents prove. in the unlv library digitization survey, 65.4 percent responded that a digitization mission statement or collection development policy was in place at their institution. one goal at unlv is to “ramp up” the number of simultaneous digitization projects underway at any one time at unlv. many items in the special collections are ripe for digitization. many of these are uncataloged, and digitizing such collections would help promote these hidden treasures. related to ramping up production, one unlv library digitization survey question asked, “on average over the past three years, approximately how many new digital collections are published each year?” responses ranged from zero new collections to sixty. the average number of new collections added each year was 6.4 for the 32 respondents who gave exact numerical answers. while this is perhaps double the unlv libraries’ current rate of production, it illustrates that increasing production is an achievable goal. staffing and funding for the unlv libraries’ digitization program have both seen increases over the past several years. a new application developer was hired, and a new graphics/multimedia specialist filled an existing vacancy. together, these staff have helped with projects such as modifying contentdm templates, graphic design, and multimedia creation related to digital projects, in addition to working on other web-based projects not necessarily related to the digitization program. another position has a job focus shifted toward usability for all things webbased, including digitization projects. in terms of funding, the two most recent projects at the unlv libraries are both the result of successful grants. the recently launched nevada test site oral history project was the result of two grants from the u.s. departments of education and energy. subsequently, a $95,000 lsta grant proposal seeking to digitize key items related to the history of southern nevada from 1900 to 1925 was funded for 2008–9, with the resulting digital collection publicly launched in may 2009. this collection, southern nevada: the boomtown years, contains more than 1,500 items from several institutions, focused on the heyday of mining town life in southern success factors and strategic planning | lampert and vaughan 123 nevada during the early twentieth century.21 this grant funded four temporary positions: a metadata specialist, an archivist, a digital projects intern, and an education consultant to help tie the digitized collection into the k–12 curriculum. grants will likely play a large role in the unlv libraries’ future digitization activities. the unlv library digitization survey asked, “has your institution been the recipient of a grant or gift whose primary focus was to help efforts geared toward digitization of a particular collection or to support the overall efforts of the digitization program?” the question sought to determine if grants had played a role, and if so, whether it was primarily large grants (defined as > $100,000), small grants (< $100,000), or both. the majority of responses (46.2 percent), indicated a combination of both small and large grants had been received in support of a project or the program. an additional 25.6 percent indicated that large grants had played a role, and 23.1 percent indicated that one or more small grants had played a role. two respondents (5.1 percent) indicated that no grants had been received or that they had not applied for any grants. the earlier arl survey asked the question, “what was/is the source of the funds for digitization activities? check all that apply.” of seven possible responses, “grant” was the second most frequent response, trailing only “library.”22 with an eye toward the future, the survey administered to arl libraries asked two blunt questions summarizing the overall thrust of the survey. one of the final open-ended survey questions asked, “what are some of the factors that you feel have contributed to the success of your institution’s digitization program?” forty respondents offered answers that ranged from listing one item to multiple items. several responses along the same general theme seemed to surface, which could be organized into rough clusters. in general, support from library administration was mentioned by a dozen respondents, with such statements as “consistent interest on the part of higher level administration,” “having support for the digitization program at an administrative level from the very beginning,” “good support from the library administration,” “support of the dean,” and, mentioned multiple times in the same precise language, “support from library administration.” faculty collaboration and interest across campus was mentioned by ten respondents, evidenced by statements such as “strong collaboration with faculty partners,” “support of faculty and other partners,” “interest from faculty,” “heavily involving faculty in particular . . . ensures that we can have continued funding since the faculty can lobby the provost’s office,” and “grant writing partnerships with faculty.” passionate individuals involved with the program and/or support from other staff in the libraries were mentioned by ten respondents, with comments such as “program management is motivated to achieve success,” “a strong department head,” “individual staff member ’s dedication to a project,” “commitment of the people involved,” “team work, different departments and staff willing to work together,” and “supportive individuals within the library.” having “good” content to digitize was mentioned by seven respondents, with statements such as “good content,” “collection strength,” “good collections,” and “availability of unique source materials.” strategic plan or goals integration was mentioned in several responses, such as “strong financial commitment from the strategic plan” and “mainstreaming the work of digital collection building into the strategic goals of many library departments.” successful grants and donor cultivation were mentioned by four respondents. other responses were more unique, such as one respondent’s one-word response—“luck”—and other responses such as “nimbleness, willingness, and creativity,” and “a vision for large-scale production, and an ability to achieve it.” the final unlv library digitization survey question asked, “what are the biggest challenges for your institution’s digitization program?” thirty-nine respondents provided feedback, and again, several variations on a theme emerged. the most common response, unsurprisingly, “not enough staffing,” was mentioned by eighteen respondents, with responses such as “lack of support for staffing at all necessary levels,” “the real problem is people, we don’t have enough staff,” “limited by staff,” and “we need more full-time people.” following this was (a likely related response) “funding,” mentioned by another nine respondents, with statements such as “funding for external digitization,” “identifying enough funding to support conversion,” “we could always use more money,” and, succinctly, “money.” related to staffing, specifically, six responses focused on technical staff or support from technical staff, such as “need more it (information technology) staff,” “need support from existing it staff,” “not enough application development staff,” and “limited technical expertise.” prioritization and demand issues surfaced in six responses, with responses such as “prioritizing efforts now that many more requests for digital projects have been submitted,” “prioritization,” “can’t keep up with demand,” and “everyone wants to digitize everything.” workflow was mentioned in four responses, such as “workflow bottlenecks,” “we need to simplify the process of getting materials into the repository,” and “it takes far longer to describe an object than to digitize it, thus creating bottlenecks.” “not enough space” was mentioned by three respondents, and “maintaining general librarywide staff support for the program” was mentioned by two respondents. the unlv libraries will keep in mind the experiences of our colleagues, as few, if any, libraries are likely immune to similar issues. 124 information technology and libraries | september 2009 n conclusions the unlv library digitization survey revealed, not surprisingly, that not all libraries, even those of high stature, are created equally. many have struggled to some extent in growing and sustaining their digitization programs. many have numerous published projects, others have few or perhaps even none. administrative and fellow colleague support varies, as does funding. additional questions remain to be tackled at the unlv libraries. how precisely will we define success for the digitization program? by the number of published collections? by the number of successful grants executed? by the number of image views or metadata record accesses? by the frequency of press in publications and word-of-mouth praise from fellow colleagues? ideas abound, but no definitive answers exist as of yet. at the larger level, other questions are looming. as libraries continue to promote themselves as relevant in the digital age, and promote themselves as a (or the) central partner in student learning, to what degree will libraries’ digital collections be tied into the educational curriculum, whether at their own affiliated institutions or with k–12 in their own states as well as beyond? clearly the profession is changing, with library schools creating courses and certificate programs in digitization. discussions about the integration of various information silos, metadata crosswalking, and item exposure in other online systems used by students will continue. library digitized collections are primary resources involved in such discussions. while these questions persist, it’s hoped that at a minimum, the unlv libraries have established the foundational structure to foster what we hope will be a successful digitization program. references 1. institute for museum and library services, “status of technology and digitization in the nation’s museums and libraries 2002 report,” may 23, 2002,

(7) and by demaine and his colleagues (8,9). the compression technique the basic technique used to compact the data file specifies that the most-frequently occurring digrams be replaced by single unused specialcharacter codes. on an eight-bit character machine of the type used, there are a total of 256 possible character codes (bytes ) . of this total only a small number are allocated to graphics (that is, characters which can be reproduced by the computer's printer). in addition, not all of the graphics provided for by the computer manufacturer appear in the user's data base. thus, of the total code set, a large portion may go unused. characters that are unallocated may be used to represent longer character strings. the most elementary form of substitution is the replacement of specific digrams. if these digrams can be selected on the basis of frequency , the compression ratio will be better than if selection is done independent of frequency. 200 journal of library automation vol. 4/4 december, 1971 this requires a frequency count of all digrams appearing in the data, and a subsequent ranking in order of decreasing frequency. once the base character set is defined, and the digrams eligible for replacement are selected, the algorithm can be applied to any string of text. the algorithm consists of two elements: encoding and decoding. in encoding, the string to be encoded is examined from left to right. the initial character is examined to determine if it is the first of any encodable digram. if it is not, it is moved unchanged to the output area. if it is a possible candidate, the following character is checked against a table to verify whether or not this character pair can be replaced. if replacement can be effected, the code representing the digram is moved to the output area. if not, the algorithm then moves on to treat the second character in precisely the same way as the first. the algorithm continues, character-by-character until the entire string has been encoded. following is a step-by-step description of the element. 1) load length of string into a counter. 2) set pointer to first character in string. 3) check to determine whether character pointed can occur in combination. if character does not occur in combination, point to next character and repeat step 3. 4) if character can occur in combination, check following character in a table of valid combinations with the first character. if the digram cannot be encoded, advance pointer to next character and return to step 3. 5) if the digram is codable, move preceeding non-codable characters (if any) to output area, followed by the internal storage code for the digram. 6) decrease the string length counter by one, advance pointer two positions beyond current value and return to step 3. in the following example assume that only three digrams are defined as codable: ab, be and de. assume also that the clear text to be encoded is the six-character string abcdef. after encoding the coded string would appear as: ab c de f a horizontal line is used to represent a coded pair, a dot shows a single (non-combined) character. the encoded string above is of length four. note that although bc was defined as an encodable digram, it did not combine in the example above because the digram ab was already encoded as a pair. the characters c and f do not combine, so they remain uncoded. note also that if the digram ab had not been defined as codable, the resultant combination would have been different in this case: a bc de f compaction of alphanumeric data j schieber and thomas 201 the decoding algorithm serves to expand a compressed string so that the record can be displayed or printed. as in the encoding routines, decoding of the string goes from left to right. bytes in the source string are examined one by one. if the code represents a single character, the print code for that character is moved to the output string. if the code represents a digram, the digram is moved to the output string. decoding proceeds byte-by-byte as follows until end of string is reached: 1 ) load string length into counter. 2 ) set pointer to first byte in record. 3 ) test character. if the code represents a single character, point to next source byte and retest. 4) if the code represents a digram: move all bytes ( if any ) up to the coded digram; and move in the digram. 5) increase the length value by one, point to next source byte and continue with step 3. application of the technique the algorithm, when used on the data base of approximately 40,000 records was found to yield 43.5% compaction. the file contains bibliographic records of the type shown in figure 1. 413.5 1970 70al350 warner m stone m the data bank societyorganizations,

535 characters ( 10) . 202 journal of library automation vol. 4/4 december, 1971 the valid graphics appearing in the data are shown in table 1, along with the percentage of occurrence of each character throughout the entire file. table 1. single-character frequency freq. freq. freq. freq. freq. graphic % graphic % graphic % graphic % graphic % b 14.87 i 4.32 h 1.58 0.63 8 0.31 e 7.63 c

occurs more frequently than is normal because of its special use as a descriptor delimiter. it should also be noted that the data contains no lower-case characters. this is advantageous to the algorithm because it considerably le~sens the total number of possible digram combinations. as a result, a larger proportion of the file is codable in the limited set chosen as codable pairs, and because the absence of 26 graphics allows the inclusion of 26 additional coded pairs. in the file used for compaction there are 58 valid graphics. allowing one character for special functions leaves 197 unallocated character codes (of a total of 256 possible ). a digram frequency analysis was performed on the entire file and the digrams ranked in order of decreasing frequency. from this list the first 197 digrams were selected as those which were eligible for replacement by single-character codes. table 2 shows these "encodable" digrams arranged by lead character. the algorithm was programmed in assembler language for use on an ibm 360/40 computer. the encoding element requires approximately 8,000 bytes of main storage; the decoding element requires approximately 2,000 bytes. in order to obtain data on the amount of computer time required to encode and decode the file, the following tests were performed. to find the encoding time, the file was loaded from tape to disk. the tape copy of the file was uncoded, the disk copy compacted. loading time for 41,839 records was 52 minutes and 51 seconds. the same tape to disk operation without encoding took 28:08. the time difference ( 24:43) represents encoding time for 41,839 records, or .035 seconds per record. a decoding test was done by unloading the previously coded disk file to tape. the time taken was 41:52, versus a time of 20:20 for unloading compaction of alphanumeric dataischieber and thomas 203 an uncompacted file. the time difference (21:32) represents decoding time for 41,839 records, or .031 seconds per record. the compaction ratio, as indicated above, was 43.5 per cent. for purposes of comparison, the algorithm developed by snyderman and hunt ( 6) was tested and found to yield a compaction ratio of 32.5% when applied to the same data file. table 2. most frequently occuring digrams lead char. a b c d e f g h i l m n 0 p r s t u v w y b 1 i ) eligible digrams ab ac ad ag ai al am an ap ar as at ab bl bo

of the algorithm currently the compression technique encodes only pairs of characters. there might be good reason to extend the technique to the encoding of longer strings-provided a significantly higher compaction ratio could be 204 journal of library automation vol. 4/4 december, 1971 achieved without undue increase in processing time. one could consider encoding trigrams, quadrigrams, and up to n-grams. the english wo~d ·'the", for example, may occur often enough in the data to make it worth coding. the arguments against encoding longer strings are several. prime among these is the difficulty of deciding what is to be encoded. doing an analysis of digrams is a relatively straightforward affair, whereas an analysis of trigrams and longer strings is considerably more costly, because of the fact that there are more combinations. furthermore, if longer strings are to be en'coded, the algorithms for encoding and decoding become more complex and time-consuming to employ. one approach to this type of extension is to take a particular type of character string, namely a word, and to encode certain words which appear frequently. a test of this technique was made to encode particular words in the data: descriptors . all descriptors (about 1200 in number) appear specially marked by slashes in the abstract field of the record. each descriptor (including the slashes) was replaced by a two-character code. after replacement, the normal compaction algorithm was applied to the record. a compaction ratio of 56.4% was obtained when encoding a small sample of twenty records ( 10,777 characters). the specific difficulty anticipated in this extension is the amount of either processing time or storage space which the decoding routines would require. if the look-up table for the actual descriptor values were to be located on disk, the time to retrieve and decode each record might be rather long. on the other hand, if the look-up table were to be in main storage at the time of processing, its size might exclude the ability to do anything else, particularly when on-line retrieval is done in an extremely limited amount of main storage area. a partial solution to this problem might be to keep the look-up tables for the most frequently occurring terms in main storage and the others on disk. at present further analysis is being done to determine the value of this approach. conclusions the compaction algorithm performs relatively efficiently given the type of data used in text data base (i.e. data without lower case alphabetics, having a limited number of special characters, in primarily english text ). the times for decoding individual records ( .031 sec/ record ) indicate that on a normal print or terminal display operation, no noticeable increase in access time will be incurred. however several types of problems are encountered when treating other kinds of data. since the algorithm works on the basis of replacing the most-frequently occurring n-grams by single-byte codes, the compaction ratio is dependent on the number of codes that can be "freed up" for n-gram representation. the more codes that can be reallocated to n-grams, the better the compaction. data which would pose complications to the algorithm-as currently defined-can be separated for discussion as follows: compaction of alphanumeric datajschieber and thomas 205 1) data containing both upper and lower case characters (as well as a limited set of special characters), and 2) data which might possibly contain a wide variety of little-used special graphics. if lower-case characters are used, a possible way to encode data using this technique is to harken back to the time-honored method of representing lower-case with upper-case codes, and upper-case characters by their value, preceeded by a single shift code (e.g., #access for access). the shift code blank character digram would undoubtedly figure relatively high on the frequency list, making it eligible as an encodable digram. the second problem occurs when one attempts to compact data having a large set of graphics. a good example of this is bibliographic data containing a wide variety of little-used characters of the type now being provided for in the marc tapes ( 11) issued by the u. s. library of congress (such as the icelandic thorn). normally representation of these graphics is done by allocating as many codes as required from the possible 256-code set. since the compaction ratio is dependent on the number of unallocated internal codes, a possible solution to this dilemma might be to represent little-used graphics by multi-byte codes which would free the codes for representation of frequently occurring n-grams. further, it is noticeable that the more homogeneous the data the higher the compression ratio. this means that data all in one language will encode better than data in many languages. there is, unfortunately, no ready solution to this problem, given the constraints of this algorithm. in dealing with heterogeneous data one must be prepared to accept a lower compression factor. without doubt to be able to effect a savings of around 40% for storage space is significant. the price for this ability is computer processing time, and the more complex the encoding and decoding routines, the more time is required. there is a calculable break-even point at which it becomes economically more attractive to buy x amount of additional storage space than to spend the equivalent cost on data compaction. yet at the present cost of direct-access storage, compaction may be a possible solution for organizations with large data files. references 1. marron, b. a.; demaine, p. a. d.: "automatic data compression," communications of the acm, 10 (november 1967),

importance of best practices and shared vocabularies. we also argue that digital accessibility benefits all users. finally, we provide recommendations for teaching librarians to collaborate with

fifteen years have seen the rise of collaborative and interactive web platforms and whiteboards, game-based learning technologies, audience polls, and other tools that contribute to student engagement in higher education classrooms. these educational tech tools have supported one-time library information literacy (il) sessions by enabling student participation in real time. still, knowing that tech tools may enhance engagement is not enough; we should also be asking whether these tech tools are accessible for all students and, if not, what can be done to make them more accessible. this paper examines the digital accessibility of five tech tools specifically for students who use assistive technologies such as screen readers. the tools are kahoot!, mentimeter, padlet,

lamont-manfre, hugen, and dickerson jamboard, and poll everywhere. these tech tools were identified in a 2021 paper inquiring which tech tools librarians used in emergency remote il instruction during the covid-19 pandemic along with their perceptions of the weaknesses and strengths of these tech tools.1 although there are guidelines aiding librarians in assessing ada accessibility around library spaces, there are no disability-related recommendations for specific tech tools used in il instruction or studies examining tech tools’ digital accessibility features. 2 there is also a lack of documentation regarding librarians’ outreach to ada-related academic offices and tech companies regarding tech tools. we argue that collaboration between libraries and ada-related offices at the campus level increases awareness of digital accessibility issues and requirements and could ultimately advance digital accessibility in educational tech tools used in il instruction. we place our paper within the context of other pandemic-responsive digital pedagogy research. we acknowledge that technology needs for student engagement are evolving in new face-to-face, hybrid, and remote instruction environments; thus, we hope to impact the way tech tools are assessed for digital accessibility and to promote the use of accessibility-tested tech tools in library instruction. first, we provide an overview of ada and digital accessibility definitions, descriptions of screen reading assistive technology, and the current use of tech tools in instruction for student engagement. secondly, we examine accessibility testing reports for the five tech tools selected for this paper. then, we discuss two trends found in the reports: shared issues between the tools and the implications of unique environments. we also argue that digital accessibility benefits all users. finally, we provide recommendations for teaching librarians to collaborate with campus offices to assess and advance the use of accessible tech tools in il instruction, thereby enhancing an equitable learning environment for all students. overview ada accessibility the americans with disabilities act (ada) was made law in 1990, signaling an initiative to protect people with disabilities from discrimination in employment opportunities, when purchasing goods, and when participating in state and local government services. 3 the idea behind the ada law was to provide equal opportunity.4 however, as health sciences librarian ariel pomputius notes, ada law protects people from discrimination, but it does not guarantee a right to accessibility beyond the legal requirements granted by this act.5 as higher education advances through the covid-19 pandemic, digital accessibility has become more essential than ever in il instruction as it takes place in hybrid, remote, and in -person environments. to ensure the digital accessibility of tech tools for all students, we should first understand its meaning. what is digital accessibility? the covid-19 pandemic brought digital accessibility to the forefront as universities navigated complex remote and hybrid learning environments. fernando h. f. botelho, a scholar with expertise in technology and disability, explains digital accessibility as the interconnection of “hardware design, software development, content production, and standards definition.”6 for botelho, accessibility is “an ongoing and dynamic process” rather than an immobilized state, where standards work together as a part of a ubiquitous process.7 as information studies information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 3 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson professor jonathan lazar notes, “digital accessibility means providing an equal user experience for people with disabilities, and it never happens by accident.” 8 georgetown law also defines digital accessibility from a perspective that may resonate with instructors who seek technologies that are accessible to all students. they define digital accessibility as “the inclusive practice of removing barriers that prevent interaction with, or access to websites, digital tools, and technologies.”9 however, it is lazar who moves the topic forward when referring to digital accessibility in research libraries, arguing that although accessibility laws protect people with disabilities, digital accessibility also benefits the whole population.10 lazar made this assertion after capturing the challenges and lessons learned related to digital accessibility during covid-19.11 the most salient lesson is that research libraries should create an infrastructure that supports digital accessibility, especially now that the covid-19 pandemic has driven universities to provide instruction in multiple formats.12 we argue that this infrastructure should also include digital accessibility evaluation of tech tools used in the classroom. assistive technology for blind users congress defined assistive technology in the disabilities act of 1988 as “any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve functional capabilities of individuals with disabilities.”13 furthermore, special education professors kathleen puckett and kim w. fisher state, “technology becomes assistive when it supports an individual … to accomplish tasks that would otherwise be difficult or impossible.”14 as scholars of occupational therapy claire kearney-volpe and amy hurst note, screen readers assist people with no or low vision by presenting web information on “a non-visual interface” via braille or speech synthesis.15 screen readers’ purpose is important because all people should have the opportunity to access the same information and services in the digital environment without facing undue barriers or burdens. the digital accessibility office’s (dao) assessment and usability team at university of colorado boulder (cu boulder) primarily tests tools for accessibility by utilizing screen reader assistive technology for both computers and mobile devices. assessment and usability staff rely on screen readers for testing because this assistive technology uses and responds to the underlying code of each webpage, application, and environment. this in-depth output makes screen readers good tools for overall accessibility testing, even though they are generally for people with no vision. however, we found no studies on tech tools and classroom engagement that consider assistive technology such as screen readers. classroom engagement with tech tools academic librarians emily chan and lorrie knight state in a 2010 study that library instruction risks being anachronistic if it does not include an engaging technology-based activity.16 with this in mind, there is ample literature documenting the impact and benefits of tech tools in the classroom. for example, authors highlight tech tools’ anonymous environment, categorized as free of judgment, noting that it is student-centered and enhances student participation.17 moreover, anonymity provides a means for students to answer honestly, fostering classroom discussion that includes introverted students.18 on the other hand, some authors argue that anonymous participation does not enhance critical thinking. ann rosnida md deni and zainor izat zainal, referring to padlet as an educational tool, information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 4 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson argue that one challenge of using tech tools to advance student engagement is that they do not, on their own, enhance criticality or discussion because students may not want to oppose their peers’ opinions.19 as with other pedagogical techniques, intentional facilitation with tech tools is necessary to enhance criticality. many authors regard the use of tech tools in the classroom positively.20 examining kahoot! to test students’ performance, darren h. iwamoto et al. state that students valued receiving immediate feedback on their answers after taking a high-stakes examination.21 carolyn m. plump and julia larosa also appreciate the use of instructional games to provide immediate feedback to students, noting that this feedback warned faculty instructors against making assumptions about how much students understand in class.22 similarly, librarian maureen knapp, referring to online tools for active learning, notes that instant feedback drives classroom discussions forward.23 liya deng, a librarian with a focus on disability studies, notes in a 2019 study that using poll everywhere in library instruction provides an opportunity to build rapport with students and a strategy to keep students focused and away from non-instruction-related internet distractions.24 engineering classes have also used tech tools to enhance teaching and learning. a 2021 case study addressing online education due to covid-19 reports that students found kahoot! to be a useful online tool that helped them reflect, apply knowledge, and receive feedback. 25 similarly, engineering educator razzaqul ashahn advocates for incorporating tech tools like jamboard for active “think-pair-share” activities, noting that it enables instructors to connect with students as they do small group work.26 these studies suggest that tech tools continue to be relevant and beneficial during the pandemic, though again, they do not consider whether they are digitally accessible. for this reason, the continued use of tech tools in various modalities (in-person, hybrid, and remote) attests to their relevance, which may continue to grow as instructors transition to pandemic-transformed pedagogy. pandemic-transformed pedagogy in a 2020 publication exploring covid-19 impacts on teaching, learning, and technology use, scholars jillianne code, rachel ralph, and kieran forde coined the phrase “pandemic-transformed pedagogy.”27 as they state, educators find themselves “on the cusp of a rapid change that is compelling them to re-think their worldview in both how they teach and how their students learn, calling for their transformation as educators.”28 a review of the recent literature available through google scholar on “pandemic-transformed pedagogy” shows expanding adoption of this phrase, including academics publishing on a range of interdisciplinary subjects and in international contexts, with implications for both k–12 and post-secondary education.29 as we reflect on this transformation and call for responsiveness to rapid change, we emphasize the need for support, planning, and advocacy for digital accessibility and tech tools. before the covid-19 pandemic, scholars at the university of sydney found in 2018 that the most significant factor driving the choice to use technology was whether it was immediately available. 30 these scholars emphasized the “just in time” use, noting that ready access to the technology required “actions, expenditure, support, and commitment from policymakers and administrators.”31 at the beginning of the pandemic, teachers, librarians, and students had a matter of days to pivot to remote work, and as ibacache, rybin koob, and vance found in a 2021 study, “availability” was a consideration for librarians in selecting tech tools for engagement and content delivery.32 this “just in time” consideration is even more important in the aftermath of covid-19, which prompted emergency remote learning. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 5 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson yet, teaching librarians also ought to go beyond what is easily available and move towards what is digitally accessible. part of the transformation we envision is to extend the concept of “pandemictransformed pedagogy” to include digital accessibility and thus push for the tech tools we use in il instruction to be readily available and digitally accessible. methodology as previously mentioned, this study examines the digital accessibility of five educational tech tools used in il instruction. to initiate a formal accessibility test, we created scripts detailing how to interact with the samples we provided for the five tools.33 these scripts were then used to manually test each tech tool for its digital accessibility using a variety of screen readers on both computers and mobile devices. about the testers the testers are native users of screen reading assistive technology and are blind. they test each tech tool first, with additional staff in the dao reviewing and validating results. about the test scripts process each test script contained the following parameters: 1. basic information about the tool. 2. contact information for access issues and technical questions, such as the tools’ customer support email and librarians’ emails for follow-up questions. 3. access points to the software and websites (urls). 4. step-by-step instructions for testers to impersonate a student engaging in an il task. as a part of these test scripts, we created short sample quizzes and activities for each of the five tools considered in this paper. in addition, the test scripts provided step-by-step descriptions to help the testers interact with the tools. the testers then tried each tool, focusing on functionality and whether they could complete the tasks in the script. the reports describe three levels of problems: severe, significant, and minor. the results section of this paper reports on these problems as found with the five tools tested. the testers also assessed general user experience (usability). the testers used a holistic approach, engaging with the entire virtual environment of the tool rather than looking only at isolated functions. assistive technology the testers utilized four types of screen reader software: voiceover, talkback, nvda, and jaws. voiceover, developed by apple, is a screen reader for mobile devices and computers that “comes standard on every iphone, mac, apple watch, and apple tv. it is gesture-controlled, so by touching, dragging, or swiping[,] users can hear what’s happening on screen and navigate between elements, pages, and apps.”34 talkback is a google-based screen reader included in android mobile devices that functions similarly to voiceover.35 nvda is a microsoft windows-only free open access screen reader supporting people who are blind or have vision impairment.36 jaws, also compatible with microsoft windows, allows people with visual impairment to read the pc screens with a text-to-speech output or via braille display.37 we also tested for visual usability issues using a free web-based color contrast analyzer.38 the testers provided thorough reports detailing the results of their testing, including exact versions used. the tests were conducted between february 27 and may 1, 2022. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 6 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson tools evaluated the educational technology tools in this study are web-based and have free options, allowing students to engage in activities using their computers or their phones. we identified these tools based on a survey about tech tool use during the covid-19 pandemic and from our own experiences.39 the tools are jamboard, kahoot!, mentimeter, padlet, and poll everywhere. jamboard is a google-powered virtual whiteboard tool. kahoot! is a quiz/game platform offering multiple styles; we tested the standard quiz question format and utilized one of the vendor provided sample quizzes. mentimeter is another quiz-making platform; we created the sample quiz utilizing multiple choice and short answer question formats. padlet is a collaborative bulletin board platform with various formats (including the three we tested: padlet maps, padlet shelf, and padlet wall). padlet includes options for users to add text and multimedia in response to question prompts or to post their own questions and other content in a collaborative virtual space. finally, poll everywhere is a polling/survey platform. limitations although digital accessibility offices at different universities commonly rely on shared standards for technology evaluation, such as web content accessibility guidelines (wcag) 2.1, we acknowledge that the assessment approach will vary from office to office. overall, there is much debate on which practices and standards for evaluating tech tools yield the best results. not all higher education institutions have digital accessibility offices, let alone accessibility and usability labs and testers. some institutions may rely on automated checkers or a mix of automated and manual testing. approaches to testing differ, and there is disagreement among digital accessibility practitioners about whether a fully automated, fully manual, or hybrid approach is best. regardless, we expect that manual testing of these educational tech tools using similar assistive technologies would have similar results during the timeframe these tools were tested. the testing reports capture a moment in time, and it’s important to note that web-based tools are frequently updated. we only tested the free versions of these tools. there may be differences in accessibility between free and paid versions. we tested only the browser versions of these tools on computers and mobile devices and did not test mobile applications, which may or may not be more accessible. this decision was made due to the probability that most il librarians and other instructors would not regularly ask students to download applications to their personal devices for in-class engagement. kahoot!, mentimeter, padlet, and poll everywhere were tested on windows, ios, and android platforms. jamboard was tested only on windows, because the browser version would not open on a mobile device using assistive technology. instead, it attempted to force an app download. we also tested each tool using sample environments and functions that we hope captured some ways the tools would be used in a typical il classroom. due to the nature of the tools and the many options available for question and collaboration formats in each tool, these samples were not exhaustive of all options available. these testing results are meant to be illustrative rather than comprehensive. finally, this study evaluated tech tools only for digital accessibility using the specific assistive technology of screen readers. further research is needed regarding how students with a rang e of different disabilities may interact with the technology tools examined here. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 7 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson results this section reports the three levels of problems (severe, significant, and minor) that dao testers found in jamboard, kahoot!, mentimeter, padlet (shelf, map, and wall), and poll everywhere. the testers also assessed user experience (“usability”). issues may be present in multiple categories based on how they impact the user’s ability to complete actions. severe issues table 1 shows the severe issues found in the tools tested. severe issues create access barriers that prevent assistive technology users from completing tasks and are issues that need to be remediated. the testers consider these issues prohibitive for many individuals with disabilities and for those who use assistive technologies. the dao identified ten severe issues in padlet shelf; five severe issues each in jamboard, padlet wall, and poll everywhere; four severe issues in kahoot!, and three severe issues in padlet map. the testers did not find severe issues in mentimeter. table 1 shows that the most common severe issue corresponds to elements that are unlabeled or inappropriately labeled. in the case of padlet map and jamboard, the testers found buttons that were unlabeled or labeled with irrelevant numbers. testers felt unclear as to what the buttons were or what their functionality was. padlet shelf contained the most unlabeled buttons, including the buttons to add posts and the three vertical dots menu to edit or delete. this issue is highly relevant since users need these buttons to navigate and contribute to the padlet. the testers observed a similar problem when using the screen reader talkback to engage with padlet shelf. talkback found unknown or unlabeled buttons, which impede users’ ability to navigate or interact with videos they submit to the padlet. figure 1 illustrates the play button located at the center of a video. in the screen reader, this button is unlabeled and appears after the video, preventing the screen reader from understanding its function and leaving users unclear whether this button is connected to the video. figure 1. the play button at the center of the video is unlabeled. in the reading order, this unlabeled button appears after the video; therefore, it is unclear what it does or how it relates to the video. the second most prevalent severe issue is elements that are not accessible to screen readers. this issue affected padlet shelf and padlet wall. in the case of padlet shelf, the testers utilizing the information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 8 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson voiceover screen reader were unable to interact with or locate gifs and graphics. when the testers utilized talkback, they would hear the gif but could not find the graphics because they were marked as links. in addition, the drawing feature was also not accessible to screen readers, including the visual elements that control colors, which appear as clickable links instead of the visual elements associated with colors. these elements were unavailable for users utilizing voiceover and jaws. the testers found a similar problem with the visual elements in padlet wall, especially when they tried to edit a post (see fig. 2). figure 2. when users want to edit a post in padlet wall, there are visual elements that are available to change the color of the post. these elements are not available to screen readers. figure 3. when images are not programmed to be read as graphics, screen readers are not able to gather information related to the gif. this image was read as “jaf3mi0ja5huk/giphy.” information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 9 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson figure 4. while using nvda, the user hears links for images that do not make sense. the third most frequent severe issue relates to graphics and gifs that are not appropriately programmed. this issue affected padlet shelf and padlet wall. when the testers were using jaws in padlet shelf, the gifs read as links with the following text: “jaf3ml0ja5huk/giphy.” when the testers utilized nvda, the gifs read as “giphy,” conveying no information describing the gif and hindering navigation (fig. 3). similarly, graphics and gifs in padlet wall are programmed as links rather than graphics. when the testers used jaws to understand graphics and gifs, they heard long links such as: “eb351cc20e6bfda76d443f1e93ad7963/pumpkin_seedling_3.” long links like this are useless to people using screen readers and disrupt people’s ability to search for graphics. when the testers used nvda, they also heard links for the images, but without the other series of characters included in jaws (fig. 4). the testers also found severe issues with elements not available by keyboard or screen reader (jamboard and poll everywhere) and timer features (kahoot!). for example, the pen, eraser, laser, shapes, and text box elements in jamboard can only be utilized or placed on the screen by a mouse, making them inaccessible to blind learners. another issue is the lack of alternative text. since jamboard offers a collaborative multi-user space, some users may post images. however, there is no way to input alternative text to an image. in the case of kahoot!, when the timer is activated, the countdown plays as the screen reader tries to read the page, confusing the screen reader and the user, who will hear the timer with random numbers and not the question. the timer feature also affects the user when starting a quiz or moving between questions. it is unclear whether the screen reader is unable to read the questions due to the short timeframe or whether the questions are truly unavailable to the screen reader. the instructor may extend the timer for quizzes in kahoot!, but it is impossible to turn it off altogether when using the kahoot! quiz question format. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 10 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson

out of seventeen problems, only one was shared by four tools (“inconsistent focus handling”), and three were shared by two tools each (“graphics are inappropriately labeled,” “reading order can be confusing to users,” and “state is not indicated”). because of this lack of overlap, brief descriptions of how frequent issues affected specific tech tools are warranted, focusing on those issues that affected multiple tools, recurred most frequently, or both. the significant issue that recurred most frequently was “reading order can be confusing to users,” affecting jamboard as well as all three padlet styles. in jamboard, when creating a sticky note, the focus of the assistive technology went into the edit field but ignored the color options. this meant that users were unable to switch between colors when making a post. reading order also caused difficulties. reading order is the way elements are tagged and read by screen readers. this may not be the same order most sighted users experience when reading elements on the page from top to bottom, though it should closely reflect the visual layout of the page. it determines what a blind learner will understand about the digital environment and in what order. in padlet map, the screen reader went through irrelevant content, including the terms and conditions, before reading the “new post” button. padlet shelf had three instances of confusing reading order; for example, the “publish” and “update” options were in the reading order above the “edit” field. the user would have to know to navigate back to finalize their post (this issue is repeated in padlet wall as well). further, if a user leaves the new post dialog box, it is difficult to return due to the reading order. the “more buttons” element was also read before the heading of a new post, and those additional buttons are unlabeled. finally, in padlet wall, the tester utilizing voiceover could not discard a post (fig. 5). a dialog opened asking for discard confirmation, but this dialog was buried in the reading order and challenging to locate. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 12 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson figure 5. a dialog box appears visually in padlet wall when a user attempts to discard a post, but it is buried in the reading order of the voiceover screen reader, making it difficult to locate and complete the task. the next most frequent significant issue was “inconsistent focus handling,” which occurred six times. focus handling directs the attention of the user and facilitates various actions in a given environment. inconsistent focus handling emerged in four out of the five tools: jamboard, kahoot!, all three padlet styles, and poll everywhere. this issue often appeared when a new element on the screen was opened, but the “focus” (what the screen reader was paying attention to at any given time) remained on the previous panel or element, causing confusion and difficulty. for example, in jamboard, when selecting the “open a jamboard” button, the panel opened visually, but the screen reader’s focus remained on the button behind the open panel. to get to the new jamboard, the tester had to navigate the other page content first. focus handling was inconsistent across many activation buttons and interactions in all three padlet styles. in kahoot!, focus handling was inconsistent across screen readers, with the focus going to different places, such as after answering a question. in poll everywhere, the focus traveled to other areas of the page after answering a question, returning to previous ques tions, or refreshing the page. these inconsistencies varied among screen readers. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 13 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson table 2. number of occurrences of significant issues found during screen reader testing for jamboard, kahoot!, mentimeter, padlet (three formats tested), and poll everywhere.

in pandemic-transformed information literacy instruction 16 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson answers announced multiple times (poll everywhere), long heading text (padlet wall), lack of notification when the user adds an image (padlet wall), excessive use of headings in a page forcing users to go through the entire page to find a heading (padlet shelf), and headings not used to provide structure and facilitate navigation. the lack of heading structure complicates the ability of users who desire to add a post with a heading and text as seen in figure 6 (padlet map). usability issues the accessibility assessment reports also included usability evaluation. usability issues may impact users of any ability. the testers noticed insufficient color contrast in three tools (poll everywhere, padlet wall and map, and kahoot!). for example, figure 7 illustrates a poll everywhere sample question where the color of the text does not have enough contrast between the text and the background. the evaluators also found a lack of color contrast in instructions and captions. in some padlet formats, the instructor can change color contrast by choosing a different template. figure 7. an example of poll everywhere answer options that do not have sufficient color contrast between the text and background. conveying meaning using colors is another issue. in the case of jamboard, the sticky note (fig. 8) has a blue bar at the bottom that appears to be loading. this bar is connected to a character count that is not noted by screen readers. in addition, the testers could continue typing past the character limit when the loading bar turned red. the testers also noticed layered elements that caused usability problems. figure 9 illustrates how the preview panel in padlet map visually blocks the post and the button to close the preview panel. padlet shelf and mentimeter did not have usability issues. information technology

bar (below the yellow box) is used as a visual indication of character limit that is not available to screen readers. figure 9. when the user has the “preview panel” in padlet map open and starts a new post, the preview panel blocks the post. summary of results the reports showed that mentimeter was the most digitally accessible tool of those considered in this study. it is important to note that kahoot! and poll everywhere were judged as relatively accessible with caveats. both jamboard and all three types of padlet tested were found to be inaccessible for many individuals who use assistive technologies. in any case, all tools included either severe or significant issues, creating a great deal of difficulty for users. most issues were unique to individual tools. of twelve severe issues, only two were shared across two tools each. of sixteen significant issues, only four were shared across tools, and only one was shared across more than two tools (“inconsistent focus handling” was a problem in all tools except mentimeter). all fourteen minor issues were unique. mentimeter, with very few issues, and padlet, with the most problems in aggregate, were outliers. because padlet offers so many different format options, we tested three, which affected the findings. still, padlet shelf had the most severe issues (ten). jamboard had the most significant issues (ten) of any tool aside from padlet. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 18 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson discussion we hypothesized that the tools selected for this study shared similar digital accessibility issues. to our surprise, the reports showed that these tech tools had few shared problems. we will thus consider two trends in the reports worthy of further examination: shared issues among the tools and unique environments. we will also discuss how digital accessibility can benefit all users of tech tools, not only people with disabilities. shared issues among the tools as previously mentioned, many issues were unique to individual tech tools covered in this study, while a few problems were shared among the tools. when a particular issue was shared among different tools, the level of severity determined whether a person using assistive technology could have a successful interaction with a tool or not. tracking shared issues and their severity may help developers and digital accessibility staff create a shared vocabulary for discussing user experience. it may also help both parties recognize when issues are common and relatively easy to remediate (e.g., labeling, heading, and alt text problems). there are other shared issues, such as focus handling inconsistencies, that are more difficult to resolve even though they are at the heart of screen reading assistive technology. tracking focus handling problems may allow developers and digital accessibility advocates to share possible solutions with one another. moreover, if tech tool developers and digital accessibility staff both understand the importance of a factor like focus handling, any difficult and severe problem can be prioritized when creating and fixing tech tools. it is also important for instruction librarians to have a basic grasp of this shared vocabulary so that they can anticipate the needs and experiences of the learners in their classrooms. looking at each tech tool in isolation offers only a tiny glimpse into the possibilities of what might happen when students connect to engagement technologies. evaluating multiple tools allowed us to better understand recurring problems and the barriers they create. unique environments though tracking shared issues is important for these reasons, by the end of our testing, we found that the tools were not similar and that even when they had shared issues, these problems had unique characteristics. for this study, we selected tools that have similar functionality (for example, both kahoot! and mentimeter can function as quiz platforms) and others that are distinctive (such as padlet maps, which incorporates gps data to allow users to interact with maps). these tools offer students real-time engagement, which helps foster a collaborative learning environment. as mentioned above, most severe issues (ten out of twelve), most significant issues (twelve out of sixteen), and all minor issues were unique—in other words, they were not shared across tools. from the testers’ point of view, the presence of unique problems is understood by the fact that the elements of each tool combine to create unique environments. for example, some tech tools are more image based, while others are text based.40 our study shows that even tools that initially appear similar are revealed as unique through assistive technology testing. an interesting finding concerned padlet. when tools have problems, these issues usually exist across all of the screen readers used for testing. padlet, however, caused inconsistencies across information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 19 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson different screen readers. for example, padlet shelf had many unlabeled or inappropriately labeled elements that created different experiences between voiceover, nvda, and jaws. moreover, when irregularities appear across similar assistive technologies, this might mean that developers created unusual code in order to facilitate specific visual elements or other aspects of the technology. developers should consider testing on multiple platforms and with two or more screen readers to catch these inconsistencies and should also consider whether simple html alternatives are possible in place of more complicated code. regarding padlet, it may be possible that software developers used accessible rich internet application code (aria-code), which is known to cause inconsistencies for assistive technology. whenever possible, user experience should be consistent across screen readers. users should never be asked to switch assistive technologies in order to adapt to a tech tool. although we sampled only five tech tools, when considering the breadth of other tools in the market and those that may not yet be developed, we wonder whether our results could indicate an abundance of unique environments with unique digital accessibility problems. this inference suggests that software developers may not be creating tech tools with digital accessibility in mind or may be testing with only one type of screen reader. it also speaks to the lack of digital accessibility best practices in software development for educational tech tools. if anything, our results also illustrate the complexity of tech tool environments and the nuances of assistive technology. digital accessibility benefits users with different abilities digital accessibility is valuable for everyone, not just people with disabilities. two specific values illustrate this comprehensive benefit. first, if standards for digital accessibility are followed, digital content will be more “portable across platforms, browsers, and operating systems.”41 this interoperability could mean that learning content and properly formatted tech tools will be easy to use across assistive technologies and devices such as smartphones. secondly, accessible features benefit people who do not see themselves as having a disability. 42 for example, covid-19 amplified the benefits of using captioning for all learners, even when these learners did not have a specific disability.43 a 2004 microsoft survey also inferred that accessibility features benefit a wide variety of people.44 while a person with a disability benefits from clear organization, headings, labels, and color contrast, those aspects are also helpful for all users. recommendations and next steps planning with intention teaching librarians need to invest time learning about the environment of a tech tool they decide to use in il instruction. sometimes, tech tools that are digitally accessible are not easy or intuitive for instructors to use. we experienced this “easy to use” versus digital accessibility conflict when preparing the scripts for mentimeter and padlet. padlet is used extensively at our institution due perhaps to its instructor-friendly platform. however, padlet’s wall, shelf, and map assessments revealed many problems with digital accessibility. additionally, we had a difficult time creating a quiz in mentimeter, finding this platform unfriendly for the instructor; yet this tool had the fewest digital accessibility problems. this tension between ease of use and digital accessibility illustrates the importance of taking time to read and understand documentation and training materials before creating engagement activities for il sessions. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 20 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson we encourage teaching librarians to work with their local digital accessibility offices to evaluate the technology used most frequently in il classrooms. if a digital accessibility office does not exist on your campus, you may wish to advocate for your administration to create one. even if your institution does not yet have a digital accessibility office, there are ways for librarians to plan their il sessions with accessibility in mind. librarians may do basic assessments of tech tools without access to assistive technology by testing whether it is possible to access all features in a given tool using the tab keyboard key. if there is a function or action that you cannot access with tab or that you must use a mouse to navigate to, then that part of the tool will not be accessible to someone using a screen reader. you can also unplug or turn off the mouse and attempt using a tech tool. librarians can approach each tech tool by asking: is there anything in the tool that uses only images or colors? do sounds convey a meaning that is not otherwise communicated on the screen? if there is anything in the tool that relies on a single form of sensory feedback, it may be unperceivable to people using assistive technology. finally, we strongly suggest considering whether these tools add value to il instruction. if you like a certain tool but know it is inaccessible (or you are unsure), consider trying a different way of involving students in the same kind of engagement. think about simplifying the tech tools that you do use. extend or turn off timers where possible if you choose to use kahoot!, mentimeter, or other quiz-making tools. avoid using questions on any platform that require users to engage with images, even if alt text is provided, because they tend to be more difficult for screen readers. pursue documentation and take time to understand various options for each tool and each question, then weigh which option will be most accessible for most students. it takes time and energy to plan ahead with intention but increasing the ability of all students to engage in learning makes the planning process worthwhile. collaboration if collaboration between librarians and digital accessibility experts is possible on your campus, take the time to talk to one another about learning outcomes and reasons for using specific tech tools. consult with experts in digital accessibility who can also help you advocate for accessibility clauses in purchase contracts before agreeing to subscribe to a given tool or service. you may also foster collaboration with an inclusive community of practice if you have one at your library. further, the teaching and learning unit on your campus may offer support for integrating technology with pedagogy to promote the engagement and learning experience of all students attending il instruction. this collaboration may be impactful for the library and the campus teaching community. as librarians with teaching responsibilities, we usually do not work in isolation. instruction librarians can also serve as a resource for teaching faculty who may want to incorporate accessible tech tools into their instruction. in addition, librarians could investigate professional organizations that provide support and development in understanding digital accessibility. while a framework for assessing tech tools for accessibility does not currently exist, the development of standards and best practices would be beneficial for librarians, software developers, and accessibility professionals alike. we hope to undertake future research and consultation to develop such frameworks with colleagues, possibly through ala round tables or acrl sections focused on instruction and accessibility. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 21 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson next steps our next steps include sharing these reports with the companies who created the five tools we tested. we will ask them to prioritize both the most severe issues and those issues that are easy to fix and that impact user experience. we will also underscore those areas that surprised us, such as inconsistencies between screen readers for the same issue in a given environment. the goal of this outreach will be to build relationships with tech tool developers so that continued dialogue and testing can occur. the ultimate goal is a more accessible learning environment for everyone with technology vendors as partners in this journey. conclusion advocating for digital accessibility in research libraries requires relationship and capacity building. the challenges faced during emergency remote learning illustrate the necessity of campus units working together to ensure student inclusion and success. increased collaborations between academic libraries, tech tool developers, and digital accessibility offices mean that all parties can benefit from mutual expertise. librarians may share the kinds of tech tools being used in il sessions, while accessibility offices may test those tools and provide recommendations for improvement, which may then be leveraged when working with software companies to advocate for positive change. if more people are aware of digital accessibility vocabulary, needs, and resources across campus, that can also augment the number of people available to respond to and triage needs when future emergencies arise. acknowledgment we would like to thank scott holman and eric klinger from the cu boulder writing center for their help revising this manuscript. information technology and

available when the creator of the survey presents them in class. we were not able to figure out a way for respondents to access group responses asynchronously. notes • we noticed that when preparing questions 4 and 6, we were not prompted to enter alt-text by default. • the creator of the poll must enable alt-text for clickable image questions (such as question 4) by going to the user profile and selecting “features lab.” • alt-text did not seem to be available for question 6. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 25 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson appendix b: digital accessibility assessment report for poll everywhere information • testing tools: o windows 10 / jaws 2021/ nvda 2021.3.1 / google chrome (most recent version) o pixel 3a, android 12 / talkback / last updated 9/30/21 o iphone 12 mini / voiceover / safari ios 14.3 • testing dates: february 27, 28, and march 3, 2022 summary this document provides an overview of the issues the digital accessibility office (dao) identified on the poll everywhere platform. overall, we found the site to be relatively accessible for many individuals with disabilities or who use assistive technologies or alternative forms of access depending on the question type. the questions with images—to rank or select—were inaccessible. that said, through our testing, we found five severe issues, two significant issues, one minor issue, and one usability issue. severe issues represent items that create access barriers and need to be remediated, significant issues represent items that create a great deal of difficulty and should be remediated, and minor issues represent items that are the lowest priority but would be good to remediate. usability issues can impact users of any ability. if there are questions, concerns, or the desire to see demos of the issues presented in this report, please reach out to the assessment & usability testing team. please also consider filling out the assessment & usability testing feedback form to help us improve our testing protocols. issues severe graphics are unlabeled or inappropriately labeled • in question 6, there are four pictures of animals. the screen readers read all four images as “unlabeled images.” there is no differentiation between the four images. appropriate image descriptions are needed. o additionally, while reviewing the history of submissions, the answers are a list that read “(an image), (an image), (an image), (an image)” information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 26 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson • there were several elements that have dots in the label name. when using voiceover, these elements were read as “unpronounceable. [braille dots] ...” followed by numbers. o these elements included the marker on the emoji image, the up and down arrow buttons on question 6, and the finished icon. element presents gesture/navigation traps • on question 6, while using voiceover and talkback, the user could not swipe between the answer options. this made the buttons, links, and text before and after the options inaccessible. o a tester was able to leave the trap, but they had to use direct touch and focus landed outside the answers. o additionally, while using talkback, there was not any indication that the image was being moved up or down. element not available by keyboard or screen reader • question 5 is an emoji question where the user would need a mouse or direct touch (while not using a screen reader) to answer successfully. the alternative text says there are emojis, but the user does not know what five emotes or different colors are presented. to activate, the user selects “enter” or double taps (mobile screen reader). this makes a random selection and places the marker in the middle of the image without a way to move the marker to the appropriate emoji. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 27 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson errors do not get focus • during one instance, a user received an error that the response was not submitted. during this one instance, the focus was not pushed to the error message. the user would have to know it was there. ideally, the focus would be pushed to the error so all users would be aware that an error had occurred. significant element state not indicated • in question 6, the unlabeled image reads as “clickable” to nvda. when selecting enter, the state of the element is not announced. visually, the image gets larger. inconsistent focus handling • focus handling for all tools could be improved. focus goes to different areas of the page after responses, returning to previous questions, or refreshing the page. o focus inconsistencies depended on the screen reader. while going through the questions, focus would go to the top of the page, “close app download offer” button, “submit,” or “next.” ideally, focus would be on the heading 1 for each question. minor same information is presented to screen reader multiple times • while using voiceover, the instructions, questions, and answers were announced multiple times. this was noted on several occasions. information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 28 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson usability insufficient color contrast (4.5:1) • in the multiple-choice question, after selecting an answer, the question’s color becomes lighter. the lighter color has insufficient color contrast for both the answer selected (2:1) and the answers not selected (1.8:1). information technology and libraries december 2022 tech tools in pandemic-transformed information literacy instruction 29 rybin koob, ibacache, williamson, lamont-manfre, hugen, and dickerson endnotes 1 kathia ibacache et al., “emergency remote library instruction and tech tools: a matter of equity during a pandemic,” information technology and libraries 40, no. 2 (2021): 8, https://doi.org/10.6017/ital.v40i2.12751. 2 there are many examples of guides which include ada compliance and library spaces, including but not limited to william w. sannwald, checklist of library building design considerations, 6th ed.

county community college. john delooper (john.delooper@lehman.cuny.edu) is web services – online learning librarian, lehman college, city university of new york. abstract in 2016, hudson county (nj) community college (hccc) deployed several wireless keyboards and mice with its imac computers. shortly after deployment, library staff found that each device’s required usb receiver (a.k.a. dongle) would disappear frequently. as a result, hccc library staff developed and deployed 3d printed port covers to enclose these dongles. this, for a time, proved very successful in preventing the issue. this article will discuss the development of these port covers, their deployment, and what worked and did not work about the project. introduction 3d printing was invented in the 1980s but remained a niche product until emerging as a mainstream technology beginning in 2009. it has been speculated that the growth in popularity was due to several factors, most notably the expiration of patents on technologies such as fused deposition modeling.1 the expiration of this patent led to the emergence of several new companies such as makerbot, which developed and released lower priced 3d printers in an effort to popularize 3d printing.2 nevertheless, early 3d printers were still more expensive than most individual consumers could afford. as with laser printers in the 1980s, many libraries combined their role in the growing makerspace movement with their community purchasing power to bring this new technology to libraries across the united states.3 libraries thus became focal points in the nascent consumer 3d printing movement, frequently providing both training and access to supplies and equipment. as the popularity of 3d printing grew, new communities of 3d printing users emerged and began to design and share artwork and practical objects created with 3d printing technology, often via communities like thingiverse and shapeways. 3d printing at hudson county community college in august 2014, the hudson county (nj) community college (hccc) library moved into a larger facility, nearly doubling its square footage. at this time, many libraries were beginning to open makerspaces, which are facilities for collaboration where the “emphasis is on creating with technology,” and hccc saw an opportunity to join this movement.4 given the results of student feedback surveys, and the observed popularity of 3d printing in public libraries, hccc librarians sought to purchase a 3d printer as a signature technology for the new makerspace. to support the new makerspace, the library’s staff implemented a series of workshops to teach students how to use the 3d printer and create their own projects. in addition, when the makerspace was not in use, the library’s administration allowed staff to experiment with the 3d printer, as well as all mailto:lsanchez@hccc.edu mailto:john.delooper@lehman.cuny.edu creating and deploying usb port covers | sanchez and delooper 92

hccc factbook, hccc is an urban institution “offering courses and classes in a wide variety of disciplines and studies in one of the most densely populated and ethnically diverse areas of the united states.”5 as of fall 2017, hccc’s full-time-equivalent student population is 7,712, and includes students representing “more than 90 nationalities.” many of these students hail from outside of the united states, “nearly 58 percent of whom speak a language other than english in their homes.” hccc’s demographics also skew young, with students ages 20 through 29 comprising approximately 52 percent of enrolled students. more recently, hccc has also increased its enrollment of high school students, as “the number of students under the age of 18, who are mostly enrolled through hccc’s various high school initiative programs, has more than quadrupled over the past five years.” as with many other community colleges, hccc’s student body includes approximately a 6:4 ratio of female to male students. the mac usb dilemma as part of the move to a new facility, the library purchased several new technologies such as computers including dell pcs and apple imacs (macs). the dell pcs came with wireless keyboards and mice, and in march 2016, the macs were switched to wireless keyboards and mice as well because their original keyboards and mice began to break down and needed replacement. students reported to library staff that the wireless keyboards and mice were a good investment, as they made it easier to move keyboards for better collaboration and for ease of storing backpacks and textbooks on desks. on both the dell pcs and the macs, the wireless keyboards and mice required the use of a small usb receiver, known as a dongle, to connect to the computer. as the wireless keyboards were installed, several library staff members raised concerns that wireless keyboards and mice would be tempting targets for theft by patrons. surprisingly, theft of keyboards and mice did not come to pass. since deployment, library staff reported no incidents of theft of any keyboards or mice. however, an unexpected type of theft soon emerged. library employees noticed that on the imacs, the type-a usb dongles, which were needed for the computers to receive input from the keyboards and mice, started disappearing. staff observed that this seemed to be a problem only among the library’s 18 macs, not its 57 dell computers, which also had wireless keyboards and wireless receivers. anecdotal observation suggested that this phenomenon emerged due to the dell’s dark color scheme, which obscured each compu ter’s usb ports, and rendered the dongles inconspicuous. in contrast, the imacs had sleek aluminum finishes, on which the dongles were more visible, and seemed to be perceived by students as flash drives (see figures 1-5). information technology and libraries | september 2019 93 figure 1. hccc imac (back with dongle shown). creating and deploying usb port covers | sanchez and delooper 94 https://doi.org/10.6017/ital.v38i3.11007 figure 2. hccc dell pc (back with dongle shown). information technology and libraries | september 2019 95 figure 3. hccc imac with usb

usb ports. these perceptions were confirmed as students started visiting service points with dongles from the macs and turning them in to library staff as “lost flash drives.” as there was frequently a lag between when a dongle was turned over to staff and the device’s initial disappearance, students began to report frustration that they would try to use a mac and find that the mouse and keyboard could not communicate with the computer. this would cause them to assume that the mac was broken, and library staff would respond by taking the computer out of service until a tech could examine it, often several hours or even days later depending on staffing. during the first semester that these keyboards and mice were deployed, the library found that almost every usb receiver was lost or stolen. this resulted in over $300 of unplanned expenses. in addition, library staff spent dozens of hours inspecting the imacs after students reported non-functioning keyboards, determining what issue was occurring, ordering replacement parts, and connecting new dongles, a process also referred to as “pairing.” to address this problem, hccc’s director of library technology sought solutions from the library’s technology staff. at a staff meeting in the spring 2016 semester, most of the members of the technology unit suggested that the library address the disappearing dongle issue by purchasing new wired keyboards and mice. the director of the technology unit felt that this was a premature solution to the issue, as he and the library administration preferred a solution that allowed the library to continue to use the wireless keyboards and mice, which were both costly and requested by the institution’s student community. during this meeting, the idea of finding port covers for the dongles arose, and one of the library’s technology associates suggested using the library’s 3d printer to create a cover that inserts into one type a usb port and would cover the dongle in the adjacent slot. the library’s technology director asked her to create a prototype, and the technology associate began work on creating this port cover. information technology and libraries | september 2019 97 methodology to create the 3d-printed port cover, the technology associate began with an online search of the 3d-printing community thingiverse, looking to see if any other 3d port covers already existed. she hoped to find an existing port cover that was both functional and easy to manufacture—in other words, quick to print, since the library’s makerbot replicator often took hours to print intricate designs and frequently jammed, due to an extruder design flaw that was common to fifth generation replicator printers.6 a thingiverse search found several varieties of port covers, but each was designed solely to occupy a port in order to prevent dust or corrosion, not to cover or hide dongles or other peripherals. since none of the existing designs adequately met the library’s needs, the technology associate created her own design using tinkercad, a web-based computer aided design (cad) program (see figure 6). figure 6. picture of port cover design in tinkercad. since each of hccc’s imac computers contained four type a ports, students would often attach other peripherals such as phone charge/sync cables or flash drives. therefore, the port cover needed to be small enough to allow room for peripherals. the technology associate thus designed a cover that would not hinder students who wanted to insert their usb flash drives or other devices, as is depicted in figures 7-10. creating and deploying usb port covers | sanchez and delooper 98 https://doi.org/10.6017/ital.v38i3.11007 figure 7. closeup of port cover. figure 7. alternate angle of port cover.

creating and deploying usb port covers | sanchez and delooper 100 https://doi.org/10.6017/ital.v38i3.11007 she then exported the tinkercad design as an stl (stereolithography) file, and printed prototypes on the makerbot replicator using pla filament. finding that her initial measurements did not quite fit, she adjusted the models one millimeter at a time, and reprinted them until the fit was secure and the dongles were covered. at this point, she printed enough covers for each mac, along with a few spares in case covers broke or wore out during normal operation. results at the beginning of the fall 2016 semester, the port covers were deployed to each of the library’s macs. during that semester, the technology associate monitored the effectiveness of the port covers. by the end of the semester, four port covers had disappeared, along with one dongle. at the beginning of the spring 2017 semester, the missing dongle was replaced, and replacement port covers were printed and deployed to the machines from which the port covers disappeared. again, the success of the port cover installation project was monitored. during this period, four port covers disappeared, along with two dongles. after the spring semester, the technology associate conferred with the director of library technology, and they decided that given the relatively low cost of 3d-printer filament used to print the dongles, and the greatly reduced receiver theft rate, this was an acceptable loss. they therefore decided to continue utilizing the port covers. but, in the fall 2017 semester, five covers and each of their corresponding dongles disappeared. then, during spring 2018 semester, all of the port covers disappeared at least once, as did the associated dongles. in total, 20 dongles were lost during that semester. the director of library technology and the technology associate conferred once again, and decided that due to this increase in theft, and a concurrent change in the college’s purchasing process, the library would abandon the 3d-printed port cover experiment. analysis after two seemingly successful semesters, library staff were proud of the changes that resulted from deploying the port cover. yet given the reoccurrence of the theft pattern in subsequent semesters, they started to worry that printing new port covers was not a sustainable practice. to that end, the technology associate considered several theories as to what would cause the port covers to disappear. for instance, research by keizer, lindenberg, and steg found that acts of social disorder (such as graffiti or litter) will spread if not stopped promptly.7 under this framework, it could be suggested that the library was too slow to respond to missing covers, and thus permitted the loss of the dongles due to insufficient action or maintenance. this theory seems logical since following an enrollment decline that began in fall 2016, a hiring freeze was instituted so as staff members left the institution, few positions were replaced. indeed, as of fall 2018, hccc’s staff is 75 percent part-time and part-timers are subject to renewal or dismissal every six months. in addition, many library employees are student workers, who often leave at graduation, and other part-time staff tend to find full-time employment or leave the library for full-time work at rates that may exceed other institutions who have more permanent staff. with limited staff resources, many of the library’s employees noted anecdotally that they were not able to give as much attention toward preventative maintenance on library computers as they had in prior semesters. therefore, they did not have time to proactively monitor equipment such as port covers and dongles. it is also possible that a novelty factor was at play. perhaps when the covers were first deployed, the brightly colored filaments stood out on the aluminum computers, making students more likely information technology and libraries | september 2019 101 to notice them and alter their behaviors accordingly. if this was the case, new students who began their coursework in subsequent semesters would not have known that port covers were an additional piece that had been added to the library’s computers in response to prior issues. following this speculation, the library’s patrons who removed port covers in fall 2017 and spring 2018 might have thought they were removing damaged or nonfunctional flash drives similarly to the students who brought what they believed were lost flash drives to library staff during the spring 2016 semester. finally, the difference in semesters could also have been due to random chance, in which case, no staff action could have affected the rate at which port covers disappeared. conclusion and future research being unsure of which of these analyses was most correct, the technology associate had planned to learn from the sudden resurgence in thefts in several ways. she planned to experiment with adding signage about the importance of dongles and the usage of port covers, and to interview student mac users to find out their perceptions about the port covers, as well as possible ideas and student-generated suggestions to prevent future thefts. she also considered designing and experimenting with printing more elaborate port covers to see if increased visibility or an elaborate shape would change theft rates. however, a complication arose during the 2018 and 2019 fiscal years. during this time, the college’s finance office changed its purchasing procedures. first, they eliminated the library’s technology budget, centralizing all technology purchases in a “pool,” whose total budget was uncertain. to make purchases from this pool, departments had to create detailed needs justification and obtain approvals from four high-level executives, in addition to the preexisting procedure of obtaining quotes and getting department head and vice president approval. while the library was eventually able to obtain funds from this process, navigating the pool process typically took about six months per purchase, which meant that, in effect, replacement dongles had to come from existing supplies. in addition, the supplies budget line, which was greatly reduced due to the enrollment decline, also came under increased scrutiny, and the purchasing department began to refuse to approve the purchase of batteries. while many of the mac keyboards were solar powered, and thus did not require batteries, all of their wireless mice, along with the wireless keyboards and mice on the windows pcs, required the use of either aa or aaa batteries. as battery supplies dwindled, the purchasing department did eventually agree to allow purchase of more batteries, under the condition that the library begin going through the pools process to purchase wired keyboards and mice. in the meantime, the technology associate continues to monitor wireless dongles, reprint port covers, and swap wired keyboards from the library’s spare parts inventory for wireless ones as dongles have disappeared. the creation of 3d-printed port covers was successful at preventing equipment loss at hccc for only two semesters before failing to fulfill that purpose. library staff speculated about the cause of this change but were unable to make that determination with certainty before budgetary changes caused the end of the 3d-printed port cover experiment. nevertheless, this project proved valuable to the library to better learn about 3d-printing technology, and to experiment with its practical uses in the library environment. endnotes creating and deploying usb port covers | sanchez and delooper 102 https://doi.org/10.6017/ital.v38i3.11007 1 filemon schoffer, “how expiring

introduction 3d printing at hudson county community college about hudson county community college the mac usb dilemma methodology results analysis conclusion and future research endnotes use of language-learning apps as a tool for foreign language acquisition by academic libraries employees articles use of language-learning apps as a tool for foreign language acquisition by academic libraries employees kathia ibacache information technology and libraries | september 2019 22 kathia ibacache (kathia.ibacache@colorado.edu) is the romance languages librarian at the university of colorado boulder. abstract language-learning apps are becoming prominent tools for self-learners. this article investigates whether librarians and employees of academic libraries have used them and whether the content of these language-learning apps supports foreign language knowledge needed to fulfill library-related tasks. the research is based on a survey sent to librarians and employees of the university libraries of the university of colorado boulder (ucb), two professional library organizations, and randomly selected employees of 74 university libraries around the united states. the results reveal that librarians and employees of academic libraries have used language-learning apps. however, there is an unmet need for language-learning apps that cover broader content including reading comprehension and other foreign language skills suitable for academic library work. introduction the age of social media and the advances in mobile technologies have changed the manner in which we connect, socialize, and learn. as humans are curious and adaptive beings, the moment mobile technologies provided apps to learn a foreign language, it was natural that self-regulated learners would immerse themselves in them. language-learning apps’ practical nature, as an informal educational tool, may attract self-learners such as librarians and employees of academic libraries to utilize this technology to advance foreign language knowledge usable in the workplace. the academic library employs a wide spectrum of specialists, from employees offering research consultations, reference help, and instruction, to others specialized in cataloging , archival, acquisition, and user experience, among others. regardless of the library work, employees utilizing a foreign language possess an appealing skill, as knowing a foreign language heightens the desirability of employees and strengthens their job performance. in many instances, librarians and employees of academic libraries may be required to have reading knowledge of a foreign language. therefore, for these employees, acquiring knowledge of a foreign language might be paramount to deliver optimal job performance. this study aims to answer the following questions: 1) are librarians and employees of academic libraries using language-learning apps to support foreign language needs in their workplace? and 2) are language-learning apps addressing the needs of librarians and employees of academic libraries? for purposes of this article, mobile language apps are those accessed through a website, and apps downloaded onto portable smartphones, tablets, desktops, and laptops. mailto:kathia.ibacache@colorado.edu use of language-learning apps | ibacache 23 https://doi.org/10.6017/ital.v38i3.11077 background mobile-assisted language learning (mall) has a user-centered essence that resonates with users in the age of social media. librarians and employees of academic libraries needing a foreign language to fulfill work responsibilities are a target group that can benefit from using languagelearning apps. these apps provide a multifaceted capability that offers time and space flexibility and adaptability that facilitates the changeable environment favored by self-learners. kukulskahulme states that it is customary to have access to learning resources through mobile devices. 1 in the case of those individuals working in academic libraries, language-learning apps may present an opportunity to pursue a foreign language accommodating their self-learning style, time availability, space, and choice of device. considering the features of language-learning apps, some have a more personal quality where the device interacts with one user while other apps emulate social media characteristics connecting a wide array of users. for instance, users learning a language through the hello talk app can communicate with native speakers all around the world. through this app, language learners can send voice notes, corrections to faulty grammar, and use the built-in translator feature. therefore, language-learning apps may not only provide self-learners a vehicle to communicate remotely, but also to interact using basic conversational skills in a given language. in the case of those working in academic libraries, this human connectedness among users may not be as relevant as the interactive nature of the device, its mobility, the convenience of the virtual learning, and the flexibility of the mobile technology. kukulska-hulme notes that the ubiquity of mobile learning is affecting the manner in which one learns.2 although there is abundant literature referring to mobile language technologies and their usefulness in students’ language learning in different school levels including higher education, scholarship regarding the use of language-learning apps by professionals is scarce.3 broadbent refers to self-regulated learners as those who plan their learning through goals and activities. 4 the author concurs that to engage in organized language learning through a language-learning app, one should have some level of organizational learning or as a minimum enough motivation to engage in self-learning. in this context, some scholars believe that the level of self-management of learning will determine the level of learning success.5 moreover, learners who possess significant personal learning initiative (pli) have the foundation to accomplish learning outcomes and overcome difficulties.6 pli may be one factor affecting learners’ motivation to learn a language in a virtual environment and away from the formal classroom setting. this learning initiative may play a significant role in the learning process, as it may influence the level of engagement and positive learning outcome. in terms of learning outcomes, language software developers may also play a role by adapting and broadening content based on learning styles and considering the elements that would provide a meaningful user experience. in this sense, bachore conveys that there is a need to address language-learning styles when using mobile devices.7 bachore also notes that as interest in mobile language learning increases, so does the different manners in which mobile devices are used to implement language learning and instruction.8 similarly, louhab refers to context dimensions as the parameters in mobile learning that consider learners’ individuality in terms of where the learning takes place, individual personal qualities and information technology and libraries | september 2019 24 learning needs, and the features of their mobile device.9 bradley also suggests that learning is part of a dialogue between the learners and their devices as part of a sociocultural context where thinking and learning occur.10 in addition. bradley infers that users are considered when creating learning activities and when improving them.11 for these reasons, some researchers address the need to focus on accessibility and developing content designed for different types of users, including differently abled learner s.12 furthermore, adaptation, according to the learner’s style, may be considered as a pivotal quality of languagelearning apps as software developers try to break the gap between formal instruction and a learner-oriented mobile learning platform. undoubtedly, the technological gap, which includes the cost of the device, interactivity, screen size, and input capabilities, among others, matter when centering on implementing language learning supported by mobile technologies. however, learning style is only one aspect in the equation. a learner’s need is another. for example: the needs of a learner who seeks to acquire familiarity with a foreign language because of an upcoming vacation may be substantially distinct from the needs of professionals such as academic librarians, who may need reading, writing, or even speaking proficiency in a given language. a user-centered approach in language-learning software design may advance the adequacy of these apps connecting them with a much wider set of learning needs. when referring to mobile apps for language learning, godwin-jones asserts that while the capability of devices is relevant, software development is paramount to the educational process.13 therefore, language-learning software developers may consider creating learning activities that target basic foreign language-learning needs and more tailored ones suitable for people who require different content. kukulska-hulme refers to “design for learning” as creating structured activities for language learning.14 although language-learning apps appear to rely on learning activities built on basic foreign language learning needs, these apps should desire to rely more on learners’ evaluative insights to advance software development that meets the specific needs of learners. although mobile technologies as a general concept will continue to evolve, its mobile nature will likely continue focusing on user experience satisfying those who prefer the freedom of informal learning. methodology instrument the author used a 26-question qualtrics survey approved by the institutional review board at the university of colorado boulder (ucb). the survey was open for eight weeks and received 199 total responses. however, the number of responses to each question varied depending on the question. the data collected was both quantitative and qualitative in nature, seeking to capture respondents’ perspectives and measurable data that could be used for statistics. the survey consisted of twelve general questions for all respondents that reported working in an academic library, then branched into either nine questions for respondents who had used a languagelearning app, and five questions for those who had not. the respondents answered via text fields, standard single and multiple-choice questions, and a single answer likert matrix table. qualtrics provided a statistical report, which the author used to analyze the data and create the figures. use of language-learning apps | ibacache 25 https://doi.org/10.6017/ital.v38i3.11077 participants the survey was distributed through an email to librarians and employees of ucb’s university libraries. the author also identified 74 university libraries in the united states from a list of members of the association of research libraries, and distributed the survey via email to ten randomly selected library employees from each of these libraries.15 the recipients included catalogers, subject specialists, archivists, and others working in metadata, acquisition, reference, and circulation. in addition, the survey was also distributed to the listserv of two library organizations: the seminar on the acquisition of latin american library materials (salalm) and reforma, the national association to promote library and information services to latinos and the spanish speaking. these organizations were chosen due to their connection with foreign languages. results use of foreign language at work of the respondents, 172 identified as employees of academic libraries (66 percent). of these, a significant percentage reported using a foreign language in their library work. the respondents belonged to different generational groups. however, most of the respondents were in the age groups of 30-39 and 40-49 years old. the respondents performed a variety of duties within the categories presented. due to incomplete survey results, varying numbers of responses were collected for each question. therefore, of 110 respondents, 82 identified their gender as female. in addition, of 105 respondents, 62 percent reported being subject specialists, 56 worked in reference, 54 percent identified as instruction librarians, 30 percent worked in cataloging and metadata, 30 percent worked in acquisition, 10 percent worked in circulation,

limited scope. other respondents alluded to technical issues with keyword diacritical, non-intuitive software and repetitive exercises. while these elements relate to the language apps themselves, one respondent mentioned missing human interaction and another reported the lack of a system to prompt learners to be accountable for their own learning process. figure 5. reasons participants had not used a language-learning app (multiple responses allowed, n=53). figure 5 shows that time restriction (i.e., availability of time to use the app) was the most prevalent reason why respondents had not used a language-learning app. however, a larger percentage of respondents answered “other” to expand on the reason they had not tried this technology. the explanations provided included: missing competent content for work; already having sufficient proficiency; preferring books, dictionaries, google translate, and podcasts; lacking interest; and having different priorities. similarly, when asked whether they would use a language-learning app if given an opportunity, a large percentage of 52 respondents answered “maybe” (65.38 percent). however, when 51 respondents answered the question: “what elements facilitated your language learning?,” 66.6 percent responded they preferred having an instructor, 54.9 percent liked being part of a classroom, and 41.1 percent liked language activities with classmates. discussion library employee use of language-learning apps the data revealed that a large number of respondents used a foreign language in their library work, reporting that reading and writing were the most needed skills. however, only about half of the respondents had used a language-learning app. therefore, there appears to be interest in language-learning apps, but use is not widespread at this time. overall, respondents felt languagelearning apps did not offer a curriculum that supported foreign language enhancement for the workplace, especially the academic library one. this factor may be one reason why respondents stopped using the apps and why this technology was not utilized more extensively. 54.71% 37.73% 32.07% 1.88% other lack of time prefer traditional setting screen too small information technology and libraries | september 2019 30 interestingly, the majority of the respondents were in their thirties and forties. one may surmise that young millennials in their twenties would be more inclined to use language-learning apps. however, the data showed a slight lead by respondents in their forties. this information may corroborate the author’s inference that generational distinctions among employees of academic libraries do not limit the ability to seek and even prefer learning another language through apps. moreover, a pew research center study showed that older generations than millennials have welcomed technology and even gen xers had a 10 percent lead on the ownership of tablets over millennials.16 referring to the device used to interact with the language app, most respondents preferred a smartphone. only a smaller fraction of respondents preferred a tablet, laptop, or desktop. this data may attest to the movability feature of language-learning apps preferred by self-learners and the notion that language learning may happen outside the classroom setting. however, while smartphones provide ubiquity and a sense of independence, so can tablets. therefore, what is it about smartphones that ignites preference from a user experience perspective? is it their ability to make calls, portability, fast processors, wi-fi signal, or cellular connectivity that makes a difference? since tablets can also be considered portable, and their larger screen and web surfing capabilities are desirable assets, is it the “when and where” that determines the device? while not all respondents reported using an app to learn a language, those who did expressed satisfaction with learning in their own space and time and with translation exercises. nevertheless, it is captivating that few respondents deemed important the ability of the software to help learners with the phonetic aspect of the language. this diminished interest in pronunciation may be connected with the type of language learning needed in the academic library profession. as respondents indicated, language-learning apps tend to focus on conversational skills rather than reading and text comprehension. in addition to those respondents who used an app to learn a new language, one respondent reported reinforcing skills in a language already acquired. a compelling matter to consider is the frequency with which respondents utilize a foreign language in their work. about a third of the respondents used a foreign language at work on a daily basis, and approximately a quarter used it weekly. this finding reveals that foreign language plays a significant role in academic library work. since the respondents fulfilled different responsibilities at their library work, one may deduce that foreign language is utilized in a variety of settings other than strictly desk tasks. in fact, as stated before, respondents reported using foreign language for multiple tasks including communicating with vendors and foreign guests as well as providing a welcoming environment, among others. even though 59 respondents stated that knowing a foreign language helped them with communication, respondents appeared to be more concerned with reading comprehension and vocabulary. it is likely reading comprehension was ranked high in the level of importance since library jobs that require foreign language knowledge tend to utilize reading comprehension skills widely. nonetheless, the author wonders whether subject specialists utilize more skills related to listening and communication in a foreign language, especially those librarians who provide instruction. therefore, it is curious that they did not prioritize these skills. perhaps this topic could be the subject for future research. notwithstanding these results, language-learning apps appear to center on content that improves listening and basic communication instead of reading use of language-learning apps | ibacache 31 https://doi.org/10.6017/ital.v38i3.11077 comprehension. therefore, the question remains as to whether mobile language apps have enough capabilities to provide a relevant learning experience to librarians and staff working in academic libraries. are language-learning apps responding to the language needs of employees working in academic libraries? the survey results indicate that language-learning apps are not sufficiently meeting respondents’ foreign language needs. qualitative data showed that there may be several elements affecting the compatibility of language-learning apps with the needs of employees working in academic libraries. however, the findings were not conclusive due to the limited number of responses. when respondents were asked to identify the unsatisfactory elements in these apps, 65.9 percent of 47 respondents found an issue with language-learning apps, but 23 percent of those respondents answered “none.” according to respondents, the main problems with apps were the lack of content and scope that was suitable for employees of academic libraries, flexibility, and grammar. perhaps mobile language-app developers speculate that some learners still use a formal classroom setting for foreign language acquisition, and therefore leave more advanced curriculum for that setting. it is also possible that developers deem more dominant a market that centers on travel and basic conversation; this may explain why these apps do not address foreign language needs at the professional level. finally, these academic library employees appear to perceive that there is a need for these apps to explore and offer a curriculum and learning activities that benefit those seeking deeper knowledge of a language. conclusion mobile language learning has changed the approach to language acquisition. its mobility, portability, and ubiquity have established a manner of instruction that provides a sense of freedom and self-management that suits self-learners. moreover, as app technology has progressed, features have been added to devices that facilitate a more meaningful user experience with language-learning apps. employees of academic libraries that have used foreign languagelearning apps are cognizant of language-learning activities that support their foreign language needs for work such as reading comprehension and vocabulary. however, language-learning apps appear to market conversational needs, providing exercises that focus on travel more than less ons that center on reading comprehension and deeper areas of language knowledge. this indicates a lack of language-learning content that would be more appropriate for those working in academic libraries. finally, academic library employees who require a foreign language in their work are a target group that may benefit from mobile language learning. presently, this target group feels languagelearning apps are too basic to cover professional, broader needs. therefore, as language-learning app developers consider service to wider groups of people, it would be beneficial for these apps to expand their lesson structure and content to address the needs of academic library professionals. endnotes 1 agnes kukulska-hulme, “will mobile learning change language learning?” recall 21, no. 2 (2009): 157,

berlin international university of applied sciences © 2023. submitted: december 22, 2022. accepted for publication: september 12, 2023. published: 18 december 2023. abstract in terms of utility and technical quality, open-source software solutions have become a common option for many libraries. as barriers to adoption have been reduced and systems such as folio appear poised to change the landscape of lis technology, it is worth examining how the use of open source can support the normative core values of librarianship and to outline a strategy for critical engagement with the technology that is beneficial to patrons and libraries. such a strategy will require further codification, institutionalization, and investigation of open source at many levels. introduction open-source software has continued to gain popularity among libraries in the past decade. it has moved from the periphery to become a major competitor with some of the most established software in the library technology sector, but implementation has been uneven and is still represented in only a small percentage of libraries. among those that have adopted open-source systems, the language used to describe the switch is often related more to pragmatism than normative concerns.1 as acceptance of open source as a legitimate technical alternative to proprietary systems has gained traction, some may be interested in reevaluating the heretofore utilitarian drivers of open source adoption and ask how it can bolster the values and ideals of librarianship. the open-source movement, while sharing some of the same civic ideals as librarianship, is not as motivationally coherent. some corners of the movement are motivated by industrial or market concerns. therefore, as open source emerges as a common option for many libraries, it is in the interests of the profession to establish, early on, the terms on which it will critically engage with open source. as software has matured and third-party support has expanded, the technical barriers to adopting open source have greatly diminished and, especially when viewed through the lens of critical librarianship, the reasons to choose open source are more pertinent than ever. as noted, for many libraries, the conversation has up until now focused, and not entirely unjustly so, largely on utility and cost-effectiveness (an unfortunately myopic view of open-source software that stops at “potential utility” and highlights “ease of installation”) while ignoring how open source can support the values of librarianship and the library’s mission. while questions of support personnel and budget are still relevant, advances in the past decade mean that they no longer must represent the entirety of the discussion of open source in libraries. libraries now have the opportunity to look at what is arguably the more fundamental reason they should adopt an open-source-first praxis, an approach where closed-source proprietary systems should only be considered as a last resort. mailto:mcilwain@berlin-international.de information technology and libraries december 2023 towards an open source-first praxis in libraries 2 mcilwain libraries have a duty to their patrons. in order to serve them well, the profession has adopted a set of associated core values such as service, privacy, equity of access, stewardship, and intellectual freedom. the use of closed-source technology presents complicated ethical questions related to, among other things, information security, privacy, and transparency. fortunately, the lis and open-source communities share many of the same core values and can support each other in addressing the deficiencies and transgressions of proprietary software. because of the lowered barriers to entry and because the values of librarianship and the opensource community complement each other so well, open-source technologies present libraries with both a pragmatic solution to better serve patrons and a solution that aligns with the values of the profession. the justification arguments for libraries to use open source represent the intersection of pragmatic, utilitarian, and moral nonutilitarian stances. however, if open source is to reinforce the mission of libraries, it must be viewed through a critical lens. librarians must ask whether efforts to develop and introduce systems that are fundamental to their missions are best led by private enterprise or by libraries themselves. the motivation of this article is to review the current state of open-source technology in lis, address common concerns, especially regarding the principles of librarianship, and critically evaluate developments in the field. the use of open-source technology presents a pragmatic opportunity for libraries, but if not approached thoughtfully, it could potentially result in a compromise of professional ethics like what has already occurred more generally with the commodification of the information profession.2 theoretical note broadly speaking, this article is informed by a critical theoretical approach. “critical theories have been applied to lis under a general umbrella of ‘critical librarianship,’ which takes an explicitly political approach to information work, seeking to promote ethical practices which support the ethical creation and communication of scholarly knowledge with a focus on implications for social justice.”3 moreover, this article advocates a praxis in line with that defined by john budd: “action that carries social and ethical implications and is not reducible to technical performance of tasks.”4 more specifically, much is owed to bergquist et al.’s application of boltanski’s and thévenot’s justification framework to the development of the free and open-source software movement.5 it is further applied here to the use of open source in lis. put briefly, the framework presents a typology that describes how actors in various settings justify means and initiatives. 6 the typology is composed of six justification logics: inspirational, related to seeking an authenticity in life via artistry; domestic, related to maintenance of a traditional status quo; popular, in which personal aggrandizement is prioritized; civic, where the common good is paramount; market, where commerce is the focus; and industrial, where qualities such as efficiency, productivity, and functionality are used to justify actions (see table 1). this framework is particularly useful in a discussion of praxis since the nuances of motivation and justification can be more easily clarified. after briefly providing context for open source, its current use in libraries, and the core values associated with librarianship, i use this framework to inform my discussion of open source and librarianship. information technology and libraries december 2023 towards an open source-first praxis in libraries 3 mcilwain table 1. boltanski’s and thévenot’s justification typology justification logic defined by inspirational authenticity in life via artistry domestic maintenance of a traditional status quo popular personal aggrandizement civic prioritization of common good market prioritization of commerce industrial efficiency, productivity, and functionality open-source technology what is discussed here as open source is known as open-source software (oss), free and opensource software (foss) or free libre open-source software (floss or f/loss); each variation representing conflicting philosophies within the movement that range from communal development for the public good to profit-maximizing neoliberal business models. in the interest of simplicity and brevity, and since it is the most commonly used term within lis literature, the terms open source and open-source software are used throughout this discussion. the concepts underpinning open source were first introduced in the 1980s as private firms began restricting access to software (specifically to its source code) under the auspices of intellectual property rights. it was at this time that the gnu general public license (gpl) was written by richard stallman, the founder of the free software foundation. it stipulated that items licensed under the gpl were subject to the “four essential freedoms” to run, study, share, and modify the information therein, and that any derivative works should be subject to those freedoms as well. this latter concept, related to derivative works, is known as “copyleft.” according to ettlinger, “many open-source and free software developers have deliberately subverted the idea of intellectual-property rights and, in the process, created a rich common to which all could contribute, according to their abilities, and from which all could benefit, according to their needs; where innovations could be shared for free.”7 following this initial period of idealistically motivated development came another decisive moment for open source when linus torvalds, while working on linux in the early 1990s, discovered that by releasing the code as he went and making it easy for others to review and contribute to, the quality of the software was much higher than if one person or team were working on it in isolation. torvalds estimated that he only coded 2% of the project himself; the remainder came from contributors.8 soon industry found it difficult to ignore a development model that offered such a cost-effective approach to making high-quality software. later, other licenses, referred to as “permissive,” were introduced that did not require that the derivative works observe the same freedoms as the original. as a result, they were seen as less hostile to intellectual property and private enterprise. while a compromise of the original principles of the free software movement, this change was seen as a major turning point for open source, as it resulted in a significant growth in the amount of, and use of, open-source software. as the foundational freedoms were de-emphasized, we see the term “open source” instead of “free software” used more often from this point forward. information technology and libraries december 2023 towards an open source-first praxis in libraries 4 mcilwain today open source is a common foundation for, or component of, proprietary software, and firms like google and microsoft are major contributors to the development of open source. likewise, in the lis sector, it is not uncommon for open-source technologies to represent significant components of closed-source systems. within these developments of the open-source movement, there can be observed three major currents of importance for the present argument, or put another way, using the concepts of justification borrowed from luc boltanski and laurent thevénot, the three justification regimes employed for the use of open source could be described as civic, industrial, and market logic.9 during its early stages, use of open-source software was dominated by a civic logic based “on principles and rules defining free software as a common good” as codified in the “four essential freedoms” of the gnu gpl license, and later by an industrial logic that prioritized quality and efficiency10 as exemplified by torvalds’s work on the linux kernel. later still we see market justification employed with the introduction of permissive licenses. this will be addressed further below, but it is worth noting here that while there are additional logics at play when justifying the use of open source in general, it is the interaction of civic, industrial, and market logic that are especially relevant here, because they are mirrored in the justification for use of open source within librarianship. open-source trends in librarianship because we share so many of the values of the oss community, we should feel an obligation to promote open source in the library community.11 at this point it is worth briefly surveying the four major pieces of open-source software used in libraries (see table 2), all of which are library systems. the discussion of open source in libraries is often focused on integrated library systems (ilss), because they represent the single largest mission-critical system that most libraries work with on a daily basis and they affect almost every operation of the library. the discussion here tends to focus on ilss as well, but that should not suggest that there are not other powerful open-source technologies available to librarians. there are notable examples in discovery systems (aspen discovery, blacklight, vufind), institutional repositories (eprints, dspace, islandora, omeka, opus 4, samvera hyrax), content management systems (drupal, subjectsplus, wordpress, etc.), wikis (bookstack, mediawiki, etc.), and analytics (matomo, umami). there are even robust open-source platforms for networking and communication such as the ascendant mastodon microblogging platform. koha one of the first and, to date, most actively developed pieces of open-source lis software is the koha ils.12 it was launched in 2000 in new zealand for a group of three libraries, and it is licensed under the gnu gpl license. it has a very active global community and many private firms that offer support. traditionally popular with small to medium-sized libraries, koha has gained traction with larger academic and public libraries in recent years. opals in 2001, six new york state school library systems came together to create what would become opals (open-source automated library system). today opals is developed by a single company, media flex, and used primarily in school libraries. “opals support is provided through districts, other service centers, or directly through media flex. although an open-source software, development for opals is performed primarily by media flex.” 13 while open source and licensed information technology and libraries december 2023 towards an open source-first praxis in libraries 5 mcilwain with gnu gpl, opals does not appear to take advantage of a collaborative development model as its source code is only available by request from media flex. 14 evergreen in 2004, the georgia public library system began development of the evergreen ils for its large consortium of public libraries, and in 2006 evergreen was launched with a gnu gpl license. afterwards a nonprofit corporation, equinox, was formed to promote, develop, and support the system. because evergreen was originally developed with large consortia or library systems in mind, it offers possibilities of scale, but requires significant resources, which may have heretofore slowed it growth. folio folio was introduced in 2016 under the apache 2.0 license which, unlike the gnu gpl, does not require that derivative works carry similar licenses as the source. this means that in the future, proprietary software can be built with folio as a base, much like the web server software of the license’s namesake, apache, is used as the base for much of the internet today. despite relatively low levels of current adoption (see table 3), folio should not be underestimated. folio is being heavily promoted and has found several high-profile early adopters, especially from the now abandoned kuali ole project. notably, in mid-2022, the library of congress announced its intent to migrate to, and support, folio.15 the folio project is currently developed under the auspices of a single-member limited liability company by the same name, nested within the open library foundation (olf), and is supported by many large libraries and library consortia, but it was ebsco that, in 2015, began exploring the possibility of creating an open-source project and has since significantly funded, promoted, and steered the project.16 ebsco, as the only “enabling partner,” has stated that it “does not expect to exert direct control” beyond “its basic expectations of an open and modular system.”17 while ebsco’s outsized role in the conception, funding, and current presence in the project must not be overlooked, it is an open-source project and many (mostly academic) libraries have been present since early on. in addition, ebsco engaged index data, a well-respected lis software firm, to develop the initial technical platform.18 index data also provides services in support of folio for libraries. table 2. open-source ilss and license types open-source ils license type koha gpl – copyleft opals gpl – copyleft evergreen gpl – copyleft folio apache 2.0 – permissive awareness and use of open source in libraries while limited to reporting about integrated library systems and platforms, marshall breeding’s annual library automation perceptions reports show a significant growth in interest in open source in the past decade. the 2012 “survey reflected fairly low levels of interest in migrating to an open-source ils, even when the company rates their satisfaction with their current proprietary information technology and libraries december 2023 towards an open source-first praxis in libraries 6 mcilwain ils and its company as poor” compared to the 2022 report that noted “open source products are a routine option in all library sectors.”19 a closer look at specific sectors reveals a more complicated picture, however. in academic libraries in the us, we see in 2019 that use of open-source software is highest among those academic institutions that offer doctoral programs and lowest among those that offer associate degrees.20 awareness was not a barrier to adoption, but among current non-adopters there were surprisingly low levels of intent.21 in contrast, among public libraries, choi found in 2021 that awareness was still a barrier for adoption and, moreover, among current non-adopters there was very low intent to migrate to open source in the near future.22 breeding’s libraries.org features an extensive database of libraries worldwide and provides data based on library type with which we may draw some inferences. again, accounting only for ilss, open-source options currently account for just around 5% of the systems among academic, public, school, and special libraries (see table 3), but again here we see an uneven distribution. the popularity of the opals system among small school libraries (78%) may distort the overall picture (see table 4). folio, despite much discussion in field, still has a relatively small footprint, even among medium to large libraries (see table 5). in general, if we exclude opals from the calculation we see similar adoption rates of around 8–10% for all libraries. special libraries have higher rates of open-source adoption ranging from 26% to 30%, but the relatively low sample sizes must be taken into account (see tables 3–5). in the end, we still see modest adoption rates among libraries of all sizes, barring some outliers among small school and special libraries. despite anecdotal evidence that interest or discussion of open source in libraries is increasing relative to 10 years ago, that does not seem to have translated into significant adoption rates and, as choi and pruett have noted, interest among nonadopters is still low.23 an important question, then, is why have open-source solutions not been more widely adopted? while beyond the scope of the current paper, evidence suggests that lack of staffing for maintenance or customization is the biggest barrier blocking adoption, but as we will see later, the introduction of more and more third-party lis it support firms could lower that barrier.24 information technology and libraries december 2023 towards an open source-first praxis in libraries 7 mcilwain table 3.

monolithic profession, there are values associated with lis and many argue that they are quite robust and coherent, even internationally. it was, after all, in 1931 when ranganathan wrote the five laws of library science, asserting that: (1) books are for use, (2) every reader his/her book, (3) every book its reader, (4) save the time of the reader, and (5) the library is a growing organism.25 ranganathan’s five laws have been interpreted and reinterpreted many times over, but in them we may recognize the values still associated with librarianship. michael gorman, the notable library scholar and former president of the american library association, expounded on and made explicit the notion of core values during his career, identifying eight: stewardship, service, intellectual freedom, privacy, rationalism, commitment to literacy and learning, equity of access, and democracy.26 foster and mcmenemy went further and compared the codes of ethics of 36 national library associations and found that of gorman’s eight values, five appeared the most often: service, privacy, equity of access, stewardship, and intellectual freedom (see fig. 1).27 looking at the values identified here by ranganathan, gorman, and foster and mcmenemy, we start to see the intersection of the pragmatic, utilitarian, and moral nonutilitarian stances that define the profession. regarding open-source technology in libraries, utilitarian considerations have heretofore dominated the discussion, but thanks to the maturation of current technologies and dialog around critical librarianship, librarians may now want to evaluate open source in light of the ethics, ideals, and values associated with lis. though there are arguably valid and mutually reinforcing relationships between many of identified values and open source, this discussion will be confined to the five most cited values identified by foster and mcmenemy in the previous paragraph because, owing to their prevalence internationally, these may be considered the most universal. information technology and libraries december 2023 towards an open source-first praxis in libraries 9 mcilwain figure 1. percentage of 36 codes of ethics studied by foster and mcmenemy that adhere to gorman’s eight core values.28 open source and libraries many librarians have long identified the shared values between the profession and the opensource community,29 but perceived barriers (outlined below) have prevented widespread adoption of open-source technologies. this section addresses the use of open source in libraries considering the five core values identified above and argues that many of those perceived barriers are misguided, outdated, or otherwise not completely applicable. service librarianship is a profession defined by service. every aspect of librarianship, every action that we take as librarians can and should be measured in terms of service. 30 perhaps the most fundamental mission of the librarian is to assist patrons in locating the knowledge they seek. in its purest form one might imagine the reference interview, the one-onone interaction between patron and librarian in which the patron is guided through various resources until the answer is found. but the reference interview only represents one point of contact and its prominence in the popular image of the librarian overshadows the other complex labor that aims to connect the patron with information resources. technology plays an enormous role in the myriad complex tasks that are performed largely in the background. indeed, as noted by barron and preater, “contemporary librarianship, as practitioners have constructed it, could not exist without library systems.”31 it is, therefore, appropriate to begin a discussion of the use of open source in libraries with a discussion of how those technologies can allow librarians to better serve their communities, specifically how technology costs and functionality can affect s ervice. information technology and libraries december 2023 towards an open source-first praxis in libraries 10 mcilwain costs cost is often the first argument made for open source in libraries and given the perennial budget constraints of many libraries, it is easy to see why. the largest cost advantage of open source comes from the elimination of license fees and support flexibility. since the code is open and not owned by anyone, vendors cannot demand fees for the use of the software or per user/per installation fees. users are free to use the software as they wish, limited in most cases only by hardware availability and in some cases technical expertise. corrado goes further and notes “open-source software not only has a lower acquisition cost than proprietary software, it often has lower evaluation/implementation and support costs as well.”32 indeed, as noted by choi and pruett in their examination of open source adoption in academic libraries, the “ability to download and test the software in advance” was the fourth most cited driver for choosing open source.33 while there are often lower costs associated with open source, there are still costs, especially with support and infrastructure. some libraries will already have the technical expertise and physical hosting capacity to maintain and run open-source systems, and other “organizations will contract with specialized firms for the services needed to operate the software with the levels of reliability and performance expected for critical business functions.”34 the perceived lack of in-house technical expertise is a common barrier among libraries that are considering open-source solutions, but here again open source presents opportunities for libraries.35 instead of a single firm that produces the software and provides support, open source allows libraries to select options best suited for them based on the on-site expertise and physical capacity already available. flexibility and avoidance of vendor lock-in are closely tied to any discussion of cost and have been noted as significant drivers in choosing open source.36 the main distinction between support for proprietary and open-source systems is that with proprietary systems, support is generally limited to the firm that developed the software. if there is an issue that requires additional expertise, a library may be required to purchase an elevated support tier or may be otherwise waiting for a bug to be fixed or feature introduced at the discretion of the firm.37 in the opensource support world on the other hand, there are more options: first with regard to the companies providing support—if company a cannot or will not provide the desired level of support, company b may be a better option—and second, there are more options from the user community—if several users want a certain feature, they may work together to develop it and contribute it back to the project, making it available for everyone. or, as with projects that have formalized decision-making structures, they may decide to become active within the governance bodies to steer a project in a certain direction. moreover, support for an issue may already be openly available in the form of online documentation or user-driven support forums. so, while potentially spending less on support and infrastructure that is at the same time more bespoke, a library can support vendors and communities whose values more closely align with their own and can avoid being locked into lengthy service agreements (vendor lock-in) with the developers of the software.38 today there is a robust ecosystem around open source, providing support and hosting solutions. arguably one of the most prominent current examples in the open-source library community is bywater solutions. bywater solutions started in 2009 to provide support for the open-source koha ils, and while it was not the first firm set up to support open-source library systems, it differed notably from some predecessors such as ptfs (née liblime) because it strived to have a collaborative relationship with the global koha community. other prominent examples include catalyst, equinox, and ptfs europe (not related to ptfs cited above). information technology and libraries december 2023 towards an open source-first praxis in libraries 11 mcilwain while cost is an oft-cited reason for interest in or adoption of open source, in 2006 marshall breeding noted that “concerted interest in open source ilss began,” not primarily out of budgetary concerns but rather frustration with the functionality of proprietary ils options.39 quality/functionality/customization as the expectations of patrons change, the need for more and more sophisticated technology increases year on year, and as the needs of each institution are different, the desire to customize that technology to meet those needs increases in kind, creating a source of tension between libraries and library software vendors in the process. private firms, especially publicly traded ones, are under pressure to make the minimum viable product to maximize profits, hardly an offense for a for-profit company, but it does represent the divergent interests of firms and libraries.40 functionality and customization are at once barriers to and drivers for adopting open-source solutions, and this fact alone demonstrates the continued misconceptions around open source in libraries.41 still, for the present argument it is sufficient to say that, despite earlier doubts around the open-source development model and the quality of the software, the continuous growth in popularity of open source has proved it is a legitimate alternative to proprietary systems in terms of quality. indeed, perhaps the strongest argument for the quality of open-source technology can be made by the firms that produce proprietary software, including in the library sector, since many of them use open-source technology in their own software. for example, ex libris’s alma system, used by 36% of academic libraries in the us in mid-2022, relies on the open-source apache solr for its search index.42 another part of providing the best service to patrons is being able to evaluate how our systems function and how they serve results. the black-box nature of proprietary systems (i.e., we know what goes in and what comes out, but have little notion of what decisions are made within ) means that librarians’ ability to serve their patrons is at times significantly hindered. for example, as corrado has noted, the inclusion or exclusion of open-access journals in the indices of proprietary discovery systems such as ebsco discovery services (eds) and ex libris’s primo, while not as opaque as academic search engines such as google scholar, is not always transparent. 43 this could represent a specific problem for some libraries, but it also speaks to a more fundamental problem. because of the nature of software development and the business models of private firms, there is an associative amount of “protected” information that may be considered trade sensitive, and whenever it is not clear how a system arrived at, or delivered, a specific piece of information, that creates a power differential and disadvantages libraries and users. smith and hanson go further to note that the uneven power dynamics in library services limits patrons’ access to information and can limit librarians’ ability to work toward socially just outcomes.44 the increased transparency of open-source systems may provide librarians the means to better serve users by allowing them to better understand how library or discovery systems are serving results to users, ultimately helping them more easily find relevant information. the current dominant paradigm in lis is that libraries pay companies for access to mission-critical systems. all support and development are provided by one firm. if there are problems or bugs, librarians must dedicate resources to reporting those to the firm to be fixed (or not) at the discretion of the developer. barron and preater, referring to galvan’s “architecture of authority,” noted that “whereas community developers are actively contributing to open source projects, systems librarians contributing to supplier-hosted community areas are providing free labor to improve a system for which they have already paid: ‘we’re one of the only industries that pays for information technology and libraries december 2023 towards an open source-first praxis in libraries 12 mcilwain the privilege of improving products, just to get them to work the way we needed them to in the first place.’”45 librarians contributing to proprietary systems (that they have already paid for) provides a particularly stark illustration of an exploitative power dynamic. of course, private enterprise will continue to profit from the unpaid labor of open-source contributors as long as their systems are built on top of open-source packages (e.g., elasticsearch, apache server and solr, nginx, and mariadb, to name the most obvious), but at least libraries will not pay twice—once for the product, second for the labor to improve the product— as in the current model. in the end, proprietary firms and open source both have the capacity to produce modern, high quality systems, but all things being equal, open source has the added advantage of transparency and control, which reinforces rather than compromises the core values of the profession. privacy libraries have an obligation to ensure the privacy of those who use their services. the use of remotely hosted proprietary software suites can make that difficult, impossible, or at the very least difficult to appraise. the dominant model for ils hosting is now one in which the provider also hosts the software on their own servers, as opposed to locally installed instances. patron data—from name, birthdate, and home address to search queries and circulation records—are now often stored in remote databases that system administrators may not have complete access to. the terms of use of this data are detailed in the vendor’s privacy policy, which may change over time. due to limited capacity, libraries may not have the time or resources to review in detail each vendors’ privacy policy or each change to that policy. remotely hosting library systems provides advantages of scale for the ils providers and may reduce the it costs of the library, while also representing an outsourcing of library it labor, but it also represents another point where we see power dynamics shifting in favor of ils firms. with less control of and access to the systems used in the library, librarians are disadvantaged. moreover, warehousing the data of many libraries in one place may create a more attractive target for nefarious actors. for libraries without on-site it knowledge, having a system hosted remotely on servers maintained by dedicated professional staff offers clear advantages, and obviously using open-source software doesn’t immediately eliminate privacy concerns, but it does shift the power dynamic back to the librarian and enhances their agency in terms of proactively protecting users’ interests. as we will see below privacy also features in discussions of stewardship and intellectual freedom. equity of access the technologies used in lis are designed to either allow librarians to better serve their patrons or, in many cases, to allow patrons themselves to directly access knowledge. they are therefore, essential to any discussion of equity of access, a “basic premise that everyone has a right to have access to library resources and services, irrespective of who they are and where and under which conditions they live.”46 making high-quality, modern technology available with the lowest possible barrier is important to providing that access, and as noted previously, producing high -quality software is one area where open-source technology excels. it was also noted above, in the discussion of cost, that depending on the required third -party support and infrastructure, open source is often a less costly solution. the absence of annual licensing fees means that a larger portion of the money invested in systems will go towards development and maintenance, activities that directly serve the user. information technology and libraries december 2023 towards an open source-first praxis in libraries 13 mcilwain stewardship according to gorman, “stewardship in the library context has three components: the preservation of the human record to ensure that future generations know what we know, the care and nurture of education for librarianship so that we pass on our best professional values and practices, [and] the care and maintenance of our libraries so that we earn the respect of our communities.”47 referring to gorman’s first point, henderson notes that, “libraries play this archival role because history has shown that it is not economically viable for profit-based businesses to do so.”48 the most pressing threat posed by closed-source technology to this concept of stewardship is longterm access to the proprietary systems and formats that contain and transmit knowledge. paradoxically, this brings us to another one of the main reasons, as identified by wilson and mitchell, that libraries are reluctant to adopt open source: “the risks involved in using oss are too great.” namely, libraries are worried about investing in systems where no single company is responsible for their development.49 while true that generally no single entity is solely responsible for development, that can be an advantage. with the barriers to the transit of capital across national borders reduced or eliminated and the liberalization of financial markets in many parts of the world comes the consolidation of industries, including the publishing and library technology sectors, a topic familiar to most librarians. when one firm acquires another, priorities may change, and as trends, tastes, and the economic environments change, technologies may be rendered uneconomical, redundant, and ultimately useless. this can mean that a piece of software or file format that was in active development one day is shelved the next, its proprietary source code permanently frozen and support for it curtailed and eventually eliminated at the earliest possible moment that is contractually possible. users are left locked into an increasingly out-ofdate technology, exposed to data security vulnerabilities (creating potential privacy issues among other problems), or faced with the costly prospect of migrating to a new system. this scenario is taken for granted today, because operating at the whims of technology firms is a common occurrence, but the open-source model offers an alternative. there is nothing preventing interest in a particular piece of open-source software from waning for some of the same reasons as mentioned for closed-source software (changing trends, tastes, etc.), but what happens next is fundamentally different. instead of the source code being permanently frozen in a firm’s archives, anyone could take the open-source code and update it or adapt it for future use. if a group of libraries are all using a piece of open-source software that is no longer actively developed by the community, they could pool their resources to adapt or update the software to their needs and maintain functionality and address security issues. intellectual freedom intellectual freedom is perhaps the most obvious value shared by the open source and lis communities. if we return briefly to the formative ideas around the open-source movement, intellectual freedom is central, especially when viewed in light of the freedoms to run, study, share, and modify source code outlined in the initial gnu gpl license. applied to traditional libraries these freedoms might be reinterpreted as read, study, share, and modify, and often “intellectual freedom begins with opposition to censorship of books and other library materials.”50 but it should apply no less to computer code. supporting open source and a model of knowledge creation that eschews copyright maximalism and embraces the information commons reinforces librarianship’s own values around intellectual freedom. to return again briefly to privacy, it is also necessary to intellectual freedom, representing another, indirect, relationship between open source and libraries promotion of intellectual freedom.51 without privacy, patrons cannot fully utilize the information resources available to information technology and libraries december 2023 towards an open source-first praxis in libraries 14 mcilwain them. “protecting information privacy allows individuals to feel free to sample the marketplace of ideas without fear of interference or scrutiny, which could inhibit curiosity.”52 the prevalence of these and other core values within the lis community are a proclamation of what is important to the profession. they help guide practitioners and help us to keep our focus on the communities we serve. that doesn’t mean there isn’t any room for interpretation; indeed, as seen in figure 1, the core values we have identified here are interpreted differently and are adhered to, to varying degrees in different places. it is the responsibility of each of us to apply these values to the work we do each day. a critical appraisal of current trends it’s hard to discuss the current state of open source in libraries without talking about folio, or the future of libraries is open. the enthusiasm behind folio is notable and its early adoption among large established academic libraries is impressive, especially for an open-source project, but the prominent role that the private sector plays in its development deserves critical examination. indeed, with the introduction of the folio library services platform (lsp), it is worth looking more closely at a strategy among private companies to leverage open-source technology (and the labor behind it) to bolster profits and reputational capital. already in 1999, eric raymond identified “open development,” a term used by linus torvalds to describe what would become known as open source, and “decentralized peer review” to “lower costs and improve software quality.”53 “open innovation,” as it became known, is a business model designed to profit from open-source technology.54 with the ascension of open innovation, the dominant justification was no longer civic but rather industrial (efficiency, quality, scale) and market (competition, profit), and there are many examples. in recent years, there has been much discussion of microsoft shipping a linux kernel inside of windows because this would have been unimaginable twenty years ago when steve balmer declared that “linux is a cancer that attaches itself in an intellectual pro perty sense to everything it touches”—presumably a reference to the gnu gpl’s requirement that derivative works carry the same open license.55 as more permissive licenses were introduced, microsoft has been making more and more moves towards interoperability between its own systems and open source. setting aside the 2014 statement from its then ceo that “microsoft ♥ linux,” microsoft’s approach to open source has been largely calculated and pragmatic, a strategy to ensure that its azure cloud computing service can host systems that the vast majority of the web runs on.56 still, its 2019 purchase of code-sharing platform github for $7.5 billion was a testament to the fact that microsoft saw value in open innovation and open source.57 the same could be said of google. when suddenly confronted with a major competitor potentially cornering the market for mobile operating systems (the 2007 release of apple’s ios), google decided to put its energies into supporting the development of the android open source project (aosp) and building proprietary components on top of it. aosp is the open-source base underpinning android. aosp is, as the name suggests, open source, whereas android includes many proprietary critical components. this is made possible because aosp is licensed with a permissive open-source license (apache 2) that does not require derivative works to have a similarly open license. as time passed, google introduced more and more closed-source components that mirrored essential aosp functionality, at which point in many cases development on the aosp counterpart ceased, at least from google’s perspective. this has left the original aosp project largely unusable without additional (now) proprietary components. information technology and libraries december 2023 towards an open source-first praxis in libraries 15 mcilwain the most explicative for our discussion however is ibm. ibm became the first major firm to pivot in supporting open source when, in 2001, it announced that it would invest $1 billion in opensource development. ibm’s then ceo lou gerstner explained the company’s shift to investing in open source and the proprietary software that it planned to develop on top of it when he earnestly commented “giving one away helps increase sales of the other.”58 pamela samuelson went further: “there are at least three stories one can tell about this shift. ibm’s adoption of open source can be viewed: as an anti-microsoft strategy; as a consequence of changed business models in the software industry; and as a manifestation of an open innovation strategy for promoting faster and more robust technical advances.”59 if we take this quote and replace ibm with ebsco and microsoft with proquest, we may have a ready-made explanation of folio as well. around the same time that its competitor proquest purchased library system developer ex libris in 2015, ebsco announced the launch of a competing open-source platform, folio. after initial discussions were carried out in the first half of 2015, formal approval arrived in the autumn of the same year, and development began in earnest soon after.60 irrespective of motivations, the decision leveraged the predictable community enthusiasm for open source, while reaping the benefits of that community’s efforts to develop the platform. according to ebsco executive vice president sam brooks, “ebsco will contribute more than any previous library vendor has to an open source project, comparable or greater than what other organizations have invested in creating proprietary lsps.”61 ettlinger notes that “through a series of calculated tactics, firms can appear to be altruistically contributing technologies to the public domain, while indirectly promoting demand for their products.”62 beyond the direct profits earned as a folio service and hosting provider, the benefits for ebsco—from gaining foundational access to a library system platform that has been built to its own specifications to acquiring reputational capital, capital that, among some in the lis community, frames the firm as a benevolent and selfless patron of libraries—are clear. librarians must evaluate whether this is the best model for libraries and their patrons. the potential benefits of a robust, versatile, and scalable open-source library system for the lis community are great, but librarians must ensure that the core values that shape the profession are not compromised during its development. alternative models the communities that have emerged around projects such as koha and evergreen are sizable and have resulted in robust systems. other examples, such as the kuali ole, were less successful. it is beyond the scope of this paper to examine the specific reasons for the relative successes of some projects compared to others, but it may be valuable to briefly explore some alternative models to private enterprise-led open-source development, since as seen above, those models may not represent the best interest of libraries or the public in terms of core values. with open source, the community around a project is key to its success, but funding and leadership are also essential. first, funding to develop open-source library systems can come from anyone who is interested in the project, but with funding comes the ability to directly or indirectly steer the project. therefore, there is a strong argument for such projects to be largely publicly funded. making libraries better and more accessible is in the public interest. libraries are a legitimate recipient of public funding, and that extends to the software that makes possible many of the services that users have come to expect. to look briefly at europe and the united states, there are several potential partners. in europe, the european union and its member states have, in recent years, committed in various ways to information technology and libraries december 2023 towards an open source-first praxis in libraries 16 mcilwain promoting and using open source.63 the eu’s stated motivations, or operational principles as first laid out in the 2018 european commission digital strategy, are digital by default, security and privacy, openness and transparency, interoperability and cross-border, and user-centric/datadriven/agile.64 there is obvious overlap here with the identified values of librarianship and the eu has already shown itself to be a valuable partner to libraries through such efforts as the europeana project.65 at the national level there are many prospective supporters present including the german research foundation (deutsche forschungsgemeinschaft) with an annual budget of €3.6 billion in 2021,66 the belgian science policy office (belspo), the dutch research council (nederlandse organisatie voor wetenschappelijk onderzoek), the french national research agency (agence nationale de la recherche), and the italian national research agency (agenzia nazionale per la ricerca) among others. in the us, the institute of museum and library services, established in 1996, is a logical source of funding as its mission is “to advance, support, and empower america’s museums, libraries, and related organizations through grantmaking, research, and policy development.”67 as for leadership, again there is a strong argument to be made for stakeholders, in this case libraries themselves, to govern and steer open-source lis projects. this requires open and transparent governance that again reflects the values of the profession, e.g., equity of access. there is a long history of national libraries leading publicly funded projects, from the library of congress developing any number of technologies, including marc records, to the koninklijke bibliotheek providing administrative support to europeana. there is also room for library consortia or associations to lead these efforts. in germany, for example, regional library consortia have been developing and sharing library-related technology for years, including widely used solutions such as dbis (datenbank-infosystem), the ezb (elektronische zeitschriftenbibliothek), and opus 4. indeed, the participation of several german library consortia (among many other international library partners) in the folio project suggests that it will not likely become locked to any one private-sector actor. though, given the foundational support provided by some, ebsco and index data in particular, it may be difficult to imagine the project continuing if that support was to suddenly vanish. as profits dictate corporate acquisitions and acquisitions dictate priorities, librarianship is often placed at a disadvantage. librarians and libraries must evaluate whether a more sustainable solution may be found in a model that is publicly funded and led by libraries. conclusion open-source technology presents a valuable opportunity to libraries and librarians to better serve their users by supporting the core values of the profession. supporting these core values is both pragmatic (aligned with the core value service) and moral-idealistic (aligned with the core values privacy, equity of access, stewardship, and intellectual freedom). at the same time, it is important for librarians to critically evaluate and challenge cultural assumptions around the current state of open source and the inherent power dynamics, and information as a commodity. awareness and use of open source continue to increase among libraries of all sizes, but research suggests disparities between different types and sizes of libraries. moreover, the nuances regarding open-source technology are rarely addressed in the literature. in order to further promote its shared values and enrich the profession, librarianship as a whole should formally address and support open source through further codification, institutionalization, and investigation. this could be done by including open source in the accreditation requirements for information technology and libraries december 2023 towards an open source-first praxis in libraries 17 mcilwain lis degree programs, for instance, inclusion in the technology section of the ala’s core competences of librarianship.68 individual librarians are encouraged to explore toolkits like awesome self-hosted (https://selfhosted.libhunt.com/) and to continue to develop and promote open source in their libraries. turning to communities such as code{4}lib (https://code4lib.org/) and the eu’s open source observatory (https://joinup.ec.europa.eu/collection/open-sourceobservatory-osor/) for questions or to share experiences is also valuable. once awareness of open source and its nuances

first issue of information technology and libraries (ital) as an open-access, eonly publication. as announced to lita members in early january, this change in publishing model will help ensure the long-term viability of ital by making it more accessible, more current, more relevant, and more environmentally friendly. ital will continue to feature high-quality articles that have undergone a rigorous peer-review process, but it will also begin expanding content to include more case studies, commentary, and information about topics and trends of interest to the lita community and beyond. look for a new scope statement for ital shortly. we’re pleased to include in this issue the winning paper from the 2011 lita/ex libris student writing award contest, abigail mcdermott’s overview on copyright law. we also have two lengthier-than-usual studies on library discovery services. the first, jason vaughan’s overview of his library’s investigations into web-scale discovery options, was accepted for publication more than a year ago, but due to its length did not make it into “print” until now, since we no longer face the constraints associated with the production of a print journal. the second study, by jody condit fagan and colleagues at james madison university, focuses on discovery-tool usability. jimmy ghaphery and erin white provide a timely overview of the results of their surveys on the use and management of web-based research guides. tomasz neugebauer and bin han offer a strategy and workflow for batch importing electronic theses and dissertations (etds) into an eprints repository. with the first open-access, e-only issue launched, our attention will be turned to updating and improving the ital website and expanding the back content available. our goal is to have all of the back issues of both ital and its predecessor, journal of library automation (jola), openly available from the ital site. we’ll also be exploring ways to better integrate the italica blog and the ital preprints site with the main site. suggestions and feedback are welcome, at the e-mail address below. bob gerrity (robert.gerrity@bc.edu) is associate university librarian for information technology, boston college libraries, chestnut hill, massachusetts. letter from the editors (march 2023) letter from the editors kenneth j. varnum and marisha c. kelly information technology and libraries | march 2023 https://doi.org/10.6017/ital.v42i1.16319 welcome to the march 2023 issue. despite the date, snow still covers the ground where the editor lives, and winter still appears to be holding on tightly to both coasts. we’re pleased to share with you the first issue of the calendar year and a collection of five peer-reviewed articles, as well as some news and updates (below). we also have a column in our public libraries leading the way series, “virtual production at cloud901 in the memphis central library” by alan ji and david mason, about how that library has adapted cutting-edge production techniques used in streaming tv shows such as the mandalorian to create virtual scenery in their teen-focused makerspace. peer-reviewed articles in the current issue are listed here: • the current state and challenges in democratizing small museums’ collections online / avgoustinos avgousti and georgios papaioannou • services to mobile users: the best practice from the top visited public libraries in the us / yan quan liu and sarah lewis • decision-making in the selection, procurement, and implementation of alma/primo: the customer perspective / jin xiu guo and gordon xu • exploring final project trends utilizing nuclear knowledge taxonomy: an approach using text mining / faizhal arif santosa • japanese military “comfort women” knowledge graph: linking fragmented digital records / haram park and haklae kim call for new editorial board members coming in april the ital editorial board, a core committee, will be issuing a call for volunteers in april. for those selected, two-year terms of service will start on july 1. editorial board members have a critical role in building the foundation for the journal’s future through setting policy and content guidelines. members of the board have several key responsibilities: • shaping the direction and strategy for the journal; • participating in online editorial board meetings; • soliciting contributions to the journal (based on personal networking, conference attendance, etc.); and • optionally reviewing articles submitted to the journal, for those who want to be involved at an even deeper level (see the peer reviewer job description). if you are interested in furthering the scholarly record for library technology and have a background in information technology in libraries, archives, or museums, this is an exciting opportunity to contribute to the profession and engage with colleagues across all types of organizations in examining the role of technology in libraries. because we want the editorial board to reflect the broad diversity of core’s membership, we especially encourage individuals from underrepresented groups and identities to apply. ital will move to a new host this summer over the past year, the editors of the three core journals—ital, library leadership & management (ll&m), and library resources and technical services (lrts)—have been working with core and the core board to consolidate our journals on a single publishing platform. we’re pleased to say that ll&m and ital will move this summer to ala’s open journal systems platform, where lrts

published. we’ll have more details to share in our june issue, before the move, but want to let you know some important details: • ital’s urls will change, but dois will continue to resolve the new home of the journal. we will work with our current host, boston college, to set up redirects to the new location. • ala uses the same publishing platform as boston college, open journal systems, so for authors and reviewers, the experience will remain the same. • articles published in ital (and our two sibling journals) will continue to be open access with no fees charged to authors or readers. authors maintain copyright in their work. we are very grateful to boston college for their support of information technology and libraries over the past decade, and to the core board for supporting this project. be a part of a future issue as the u.s. academic year hurdles to a close this spring, it’s a great time to think about the work you’ve accomplished and what you might share with your library colleagues near and far. our call for submissions outlines the topics of interest to the journal—basically, if the submission discusses the intersection of libraries/archives/museums and technology, it’s potentially in scope—and the process for submitting an article. we’d love to consider your article for publication. or, if you have an idea you’d like to discuss with ital’s editors, contact either of us at the email addresses below. kenneth j. varnum, editor marisha c. kelly, assistant editor varnum@umich.edu marisha.librarian@gmail.com

kilgour: director, ohio college library center, columbus, ohio. an experiment showing that 3, 1, 1, 1 search keys derived from titles are sufficiently specific to be an efficient computerized, interactive index to a file of 135,938 marc ii records. this paper reports the findings of an experiment undertaken to design a title index to entries in the ohio college library center's on-line shared cataloging system. several large libraries participating in the center requested a title index because experience in those libraries had shown that the staff could locate entries in files more readily by title than by author and title. users of large author-title catalogs have long been aware of great difficulties in finding entries in such catalogs. since the center's computer program for producing an author-title index could be readily adapted to produce a title index, it was decided to add title access to the system. a previous paper has shown that truncated three-letter search keys derived from the first two words of a title are less specific than authortitle keys ( 1). earlier work had revealed that addition of only the first letter of another word in a title improved specificity ( 2) . therefore, the experiment was designed to test the specificity of keys consisting of the first three characters of the first non-english-article word of the title plus the first letter of a variable number of consecutive words. the experiment was also designed to produce an index that catalogers could use efficiently and that would operate efficiently in the computer system. it was assumed that the terminal user would have in hand the volume for which an entry was to be sought in the on-line catalog. the index was not to be designed for use by library users; subsequent experiments will be done to design an index for nonlibrarian users. other investigations into computerized, derived-key title indexes include 18 journal of library automation vol. 5/1 march, 1972 the previous paper in this series to which reference has already been made ( 1) and development of a title index in stanford's ballots system ( 3). although stanford has not published results observed from experiment or experience that describe the retrieval specificity of its technique, it is clear that the stanford procedure is not only more powerful than the one described in this paper but also more adaptable for user employment. the stanford index is probably less efficient. materials and methods a file of 135,938 marc ii records was used in this experiment. this file contains title-only and name-title entries, and keys were derived from titles in both types of entries. a key was extracted consisting of the first three characters of the first non-english-article word of each title plus the first character of each following word up to four. if there were fewer than four additional words, the key was left-justified, with trailing blank fill. only alphabetic and numeric characters were used in key derivation; alphabetic characters were forced to uppercase. all other characters were eliminated and the space occupied by an eliminated character was closed up before the key was derived. a total of 115,623 distinct keys was derived from the 135,938 entries. these 115,623 keys were then sorted. each key in the file was compared with the subsequent key or keys and equal comparisons were counted. a frequency distribution by identical keys was thus prepared, and a table constructed of percentages of numbers of equal comparisons based on the total number of distinct keys. this table contains the percentage of time for expected numbers of replies based on the assumption that each key had a probable use equal to all other keys. next, by eliminating the fourth single character and then the fourth and third, files of 3,1,1,1 and 3,1,1 keys were prepared from the 3,1,1,1,1 file. for example, the 3,1,1,1,1 key for raymond irwin's the heritage of the english library is her, 0, t, e , l; the 3,1,1,1 key for this title is her, 0 , t, e; and the 3,1,1 key, her, 0 , t. the same processing given to the 3,1,1,1,1 file was employed on these two files. results table 1 contains the maximum number of entries in 99 percent of replies. inspection of the table reveals that there is a large increase in specificity when the key is enlarged from 3,1,1 to 3,1,1,1; the maximum number of entries ( 99+ percent of the time) drops from twelve to five. however, when the key goes to 3,1,1,1,1, the number of entries per reply goes down only to four from five. the percentage of replies that contained a single entry was 67.8 for the 3,1,1 key, 84.0 for the 3,1,1,1 key, and 90.0 for the 3,1,1,1,1 key. a truncat ed search key / long and kilgour 19 table. 1.

3,1,1 search key is not sufficiently specific to operate efficiently as a title index in a large file. however, the 3,1,1,1 key appears to be sufficiently specific for efficient operation, while the 3,1,1,1,1 key does not appear to possess sufficient increased specificity to justify its additional complexity. the observation that there is a large increase in specificity between keys employing threeand four-title words that constitute markov strings suggests that the second and third words may be highly correlated. indeed this suggestion is substantiated b y the maximum case for 3,1,1-his, 0, t. in the more-than-eighteen group for 3,1,1,1, these characters occurred in seven keys for a total of 206 entries, and for 3,1,1,1,1 they did not occur at all in the more-than-eighteen group. conclusion this experiment has shown that a 3,1,1,1 or 3,1,1,1,1 derived search key is sufficiently specific to operate efficiently as a title index to a file of 135,938 marc ii records. since a previous paper observed that as a fil e of entries increases the number of entries per reply does not increase in a one-to-one ratio ( 1 ), it is likely that these keys will operate efficiently for files of considerably greater size. 20 journal of library automation vol. 5/1 march, 1972 references 1. frederick g. kilgour, philip l. long, eugene b. leiderman, and alan l. landgraff, "title-only

in this issue lib-s-mocs-kmc364-20141005044017 catalog records retrieved by personal author using derived search keys 103 alan l. landgraf and frederick g. kilgour: the ohio college library center this investigation shows that search keys derived from personal author names possess a sufficient degree of distinctness to be employed in an effi~ cient computerized interactive index to a file of marc ii catalog records having 167,7 45 personal author entries. previous papers in this series and experience at the ohio college library center have established that truncated derived search keys are efficient for retrieval of entries by name-title and title from large on~line computerized files of catalog records. 14 experiments reported in the earlier papers were " ... based on the assumption that each key had a probable use equal to all other keys."5 however, guthrie and slifko have shown that random selection of entries, rather than keys, yields results closer to actual experience but with a higher number of entries per reply.6 for example, they found on retrieving from a file of 857,725 records using a 4, 5 (four characters of main entry, five characters of title) key tl1at when the basis of the search was random keys there was one entry per reply 81.3 percent of the time, but when the basis was random records, there was one entry per reply 55.7 percent of the time. this paper presents the results of experimentation with search keys to be used in constructing an author index to a large file of on-line catalog records. an interactive environment is assumed, with the interrogator employing a remote terminal. a companion paper de:;etibes the findings of an investigation into retrieval efficiency of search keys derived from corporate author names.7 materials and methods the investigation employed a marc ii file containing approximately 200,000 monographic records from which a computer program extracted 167,745 personal-name keys. the program extracted these keys from main entry, series statement, added entry, and series added entry fields. the basic key structure consisted of sixteen characters-the first eight from the surname, the first seven from the forename, and the first character from the middle name ( 8,7,1). if the surname and forename contained fewer char104 journal of libmry automation vol. 6/ 2 june 1973 ~ likelihood 90.00%

this journal and with this issue we’ve decided to begin a new column. in each issue of ital, one of our board members will reflect on some question related to technology and libraries. we hope you find this new feature thought-provoking. enjoy! any librarian who has been following the profes-sional literature at all in the past ten years knows that there has been an increasing emphasis on user-centeredness in the design and creation of library services. librarians are trying to understand and even anticipate the needs of users to a degree that’s perhaps unprecedented in the history of our profession. it’s no mystery as to why. we now live in a world where global computer networks link users directly with information in such a way that often, no middleman is required. users are exploring information on their own terms, at their own convenience, sometimes even using technologies and systems that they themselves have designed or contributed to. at the same time, most libraries are feeling a financial pinch. resources are tight, and local governments, institutions of higher education, and corporations are all scrutinizing their library operations more closely, asking “what have you done for me lately?” the unspoken coda is “it better be something good, or i’m cutting your funding.” the increasing need to justify our existence, together with our desire to build more relevant services, is driving an increased interest in assessment. how do we know when we’ve built a successful service? how do we define “success?” and, perhaps most importantly, in a world filled with technologies that are “here today, gone tomorrow,” how do we decide which ones are appropriate to build into enduring and useful services? as a library technologist, it’s this last question that concerns me the most. i’m painfully aware of how quickly new technologies develop, mature, and fade silently into that good night with nary a trace. it’s like watching protozoa under a microscope. which of these can serve as the foundation for real, useful services? it’s obvious to me that if i’m going to choose well, it’s vital that i place these services in context—and not my context, the user context. in order to do that, i need to understand the users. how do they do their work? what are they most concerned with? how do they think about the library in relation to the research process? how do they use technology as part of that process? how does that process fit into the larger context of the assignment? to answer questions like these, librarians often turn to basic marketing techniques such as the survey or the focus group. whether we are aware of it or not, the emphasis on user-centered design is making librarians into marketers. this is a new role for us, and one that most of us have not had the training to cope with. since most of us haven’t been exposed to marketing as a discipline of study, we don’t think of what we do as marketing, even when we use marketing techniques. but that’s what it is. so whether we know it or not, marketing, particularly market research, is important to us. marketing as a discipline is in the process of undergoing some major changes right now. recent research in sociology, psychology, and neuroscience has uncovered some new and often startling insights into how human beings think and make decisions. marketers are struggling to incorporate these new models into their research methods, and to change their own thinking about how they discover what people want. i recently collided with this change when my own library decided to do a focus group to help us redesign our website. since we have a school of business, i asked one of our marketing professors for help. her advice? don’t do it. as she put it: “you and the users would just be trading ignorances.” she then gave me a reading list, which included how customers think by gerald zaltman, which i now refer to as “the book that made marketing sexy.”1 zaltman’s book pulls together a lot of the recent research on how people think, make choices, and remember. some of it is pretty mind-blowing: n 95% of human reasoning is unconscious. it happens at a level we are barely aware of. n we think in images much more than we do in language n social context, emotion, and reason are all involved in the decision-making process. without emotion, we literally are unable to make choices. n all human beings use metaphors to explain and understand the world around them. metaphor is the bridge between the rational and emotional parts of the decision-making process. n memory is not a collection of immutable snapshots we carry around in our heads. it’s much more like a narrative or story—one that we change just by remembering it. our experience of the past and present are inextricably linked—one is constantly influencing the other. heady stuff. if you follow many of these ideas to their logical conclusions, you end up questioning the value of many traditional marketing techniques, such as surveys and focus groups. for example, if the social context in 4 information technology and libraries | june 2008 kyle felker (felkerk@wlu.edu) is an ital editorial board member, 2007–09, and technology coordinator at washington and lee university library in lexington, virginia. editorial board thoughts kyle felker ital board member’s column | felker 5 which a decision is made is important, then surveys are often going to yield false data, since the context in which the person is deciding to tick off this or that box is very different from the context in which they actually decide to use or not use your service or product. asking users “what services would be useful” in a focus group won’t be effective because you are only interviewing the users’ rational thought process—it’s at least as important to find out how they feel about the service, your library, the task itself, and how they perceive other people’s feelings on the subject. zaltman proposes a number of very different marketing techniques to get a more complete picture of user decision making: n use lengthy, one-on-one interviews. interviewing the unconscious is tricky and takes trust, it’s something you can’t do in a traditional focus group setting. n use images. we think in images, and images are a richer field for bringing unconscious attitudes to the surface. n use metaphor. invite interviewees to describe their feelings and experiences in metaphor. explore the metaphors they come up with to more fully understand all the context. if this sounds more like therapy than marketing to you, then your initial reaction is pretty similar to mine. but the techniques follow logically from the research zaltman presents. how many of us have done user assessment and launched a new service, only to find a less than warm reception for it? how many of us have had users tell us they want something, only to see it go unused when it’s implemented? zaltman’s model offers potential explanations for why this happens, and methods for avoiding it. lest you think this has nothing to do with technology, let me offer an example: library facebook/myspace profile pages. there’s been a lot of debate on how effective and appropriate these are. it seems to me that we can’t gauge how receptive users are to this unless we understand how they feel about and think about those social spaces. this is exactly the sort of insight that new marketing techniques purport to offer us. in fact, if the research is right, and there is a social and emotional component to every choice a person makes, then that applies to every choice a user makes with regard to the library, whether it’s the choice to ask a question at the reference desk, the choice to use the library website, or the choice to vote on a library bond issue. librarians are doing a lot of things we never imagined we’d ever need or want to do. web design. archival digitization. tagging. perhaps it’s also time to acknowledge that what we do has an important marketing component, and to think of ourselves as marketers (at least part time). i’m sold enough on zaltman’s ideas that i’m willing to try them out at my own institution, and i encourage you to do the same. reference 1. zaltman, gerald. how customers think: essential insights into the mind of the market (boston, mass.: harvard business school press, 2003.) 66 journal of lihm1'y automation vol. 7/1 march 1974 book reviews computer systems in the library: a handbook for managers and designers. by stanley j. swihart and beryl f. hefley. a wiley-becker & hayes series book. los angeles: melville publishing company, 1973. 388p. once every year or two, either in england or the united states, a book appears attempting to explain computer systems to librarians. this book, compute?' systems in the library, is the most recent of the introductory texts. it starts off with a chapter entitled "why automate?" which skims ve1y lightly and uncritically over the often-repeated reasons for using computers. in this instance, money is included as a reason to automate, for we are told that "when properly planned, unit operating costs are normally reduced when a function is automated." automation's impact on the library's research and development budget is not discussed. the book then proceeds to the six chapters which occupy the bull< of the book they cover the automation of six major librmy functions: catalog publication, circulation, acquisitions, cataloging, catalog reference services, and serials. each chapter consists of a description of one or two apparently existing automated systems, with a complete discussion of how the system functions, what files are involved, the data in each file, coding and formats used in the files, and reproductions of various output products from each file. unfortunately, we are not told where each of these systems exists, and the systems often appear to use techniques that are suitable only for very small libraries. for example, in the circulation system that is described, a packet of prepunched book cards is to be carried in the book; each time the book is charged or discharged one of the cards is removed, with the last card serving as a signal to create a new deck of cards. little mention is made of the data collection terminals that are so commonly used in automated circulation systems, with the result that the description is very closely linked to a single system, with little opportunity for the reader to compare various methods or techniques of information handling. the latter part of the book addresses itself to some general problems, including the interlibrary sharing of data and programs; the planning, implementation, and control of automation projects; and brief discussions of input and output problems, the protection of records, and some considerations in choosing hardware. three appendixes offer a 2,500-word exclusion list for kwic indexes, a set of model keypunching rules for a corporate library, and a thirty-three-item bibliography in which the majority of works listed were published between 1964 and 1968. a major weakness of the book seems to be its lack of critical focus. library automation problems are treated as being not particularly difficult; in fact, "the authors can see no serious or major disadvantages to automation in libraries. the situation," we are told, "can be compared with the disadvantages of using typewriters or telephones." this reviewer finds it difficult to know what sort of audience these words, and the entire book, are addressed to. though subtitled "a handbook for managers and designers," it would be an inexperienced manager indeed who needed to be told that "in its mode of operation, a keypunch is quite similar to a typewriter. a key must be struck for each character . . . ," or that "the catalog master file may be stored on magnetic tape reels or on magnetic disks." the experienced librarian, on the other hand, will not be pleased to learn that "many libraries with computer systems have given up the library of congress [filing] system for mel mac and have placed mac in order between mab and mad, and me between mb and md." nor will anyone associated with libraries be pleased to discover that "computer centers not only can, but frequently do, lose information. from time to time complete files are erased. there is almost no way to ensure that information will not be inadvertently erased." the librarian who is already involved in automated systems will not need this book; the librarian who wishes to learn about automation and the systems analyst who needs to understand library systems will do well to read other sources in addition to this one. peter simmons university of british columbia the metropolitan library. edited by ralph w. conant and kathleen molz. cambridge, mass.: m.i.t. press, 1972. 333p. $10.00. the editors describe this book as a sequel to the important public library and the city (1965), also published by m.i.t. press. the focus again is on the concerns of metropolitan public librarians, combining the viewpoints of specialists from library and social science disciplines. of the eighteen papers included, only three, by john trebbel, john bystrom, and kathleen molz, concentrate on the implications of present and future technology on public library service. their papers offer a general, if hard-nosed, approach to the need for specific research into the economic, behavioral, professional, and technological barriers impeding the advent of the automated millenium. micrographics, reprography, computers, facsimile transmission, telecommunications hardware, and technology are considered essential components of information transbook reviews 61 fer with which libraries must become compatible-and comfortable. the ijllperative need for and conduct of long-range research in telecommunications is outlined by bystrom, including aspects of research necessary for both a national telecommunications network linking all types of libraries and the local use of community cablevision by individual library outlets. the three authors devote considerable head-shaking to the chilling reality of financing technological adaptations and innovations in libraries-the "snake in eden" according to trebbel. governments, specifically national governments, are cited as the logical sources of the enormous sums required for automated library and information services of whatever

insupportable. the public library must adapt to a multimedia world. none of the foregoing is new to 'information scientists or specialists in automation, but as concerned participants in the knowledge

roberts: the library, university of california, san francisco a quarterly keyword index to campus grant projects is provided by the health science library at the university of california, san francisco, using a data base created and maintained by the campus' contracts & grants office. the index is printed in kwoc format, using the chief investigator's name as the key to a section of project summaries. a third section is also included, listing the summaries under the name of the sponsoring department. introduction communication channels between the computer center and the library at the university of california, san francisco are open despite the "normal" and accompanying library use traumas of an all-purpose university computi.rig center. thus the library's chief administrator received an immediate, if unexpected, response to her statement of campus need for subject access to information about local research and training projects. as she summarized it, the information need is expressed as "who is doing what, where, with what amount of funds?" such queries about campus work come to the health science library regularly, but had often remained unanswered because of inadequate published sources and the lack of easily accessible local sources. neither the campus contracts and grants ( c&g) office, nor any other campus unit, had files organized to allow inquiry by subject or by department name, nor were any departments staffed to provide a general information service of this nature. previous investigation by the library had revealed the fiscal infeasibility of extracting citations of publications on campus research projects from a commercially available data base. the latest locally compiled directory of campus work was eleven years old. response by the computer center director to the library statement was a suggestion for a three-department cooperative project between the library, the computer center, and the c&g office to produce a quarterly index of the machine-readable administrative file of the latter department. this accession-ordered file is comprised of 1441-character records which provide for 42 data elements needed by the c&g office to monitor the progress and fiscal status of all extramurally funded projects and proposals (figure 1). grant project information/roberts 163 214g-1000.40 d0+15 1g404~61 .. 1fdrshan

of a 5-digit "discipline" code; this code had quickly become null when problems of maintenance and interpretation revealed themselves. however, the regular monthly entry and updating of other descriptive data was already twelve months underway at the time the cooperative project was suggested. library index the original proposal for a library index to the c&g file was production of a standard kwic (keyword-in-context) index to project titles, to be based on use of an ibm share library program developed by computer center staff. after review of available library programs and output, the product was finally specified to be a kwoc (keyword-out-of-context) index to project titles, using the chief investigator's name as key to a second 'bibliographic" section of project summaries (figures 2, 3). a third section was added to list project summaries indexed by campus department name (figure 4). the c&g file included 12 elements which the library considered to be of general campus interest. these elements, comprising the project summaries, are: ( 1) project title; ( 2) chief investigator's name; ( 3) award status (i.e., funded or proposed); ( 4) project site (i.e., campus or affiliated institution); ( 5) project type (e.g., training, basic research, applied research); ( 6) grant number; ( 7) total project duration to date; ( 8) award period; ( 9) award

man-weeks of library staff time and less than a week's time of computer center staff. total cpu time used was two hours, a significant portion of this time representing compiler rather than program testing. the c&g administrative analyst reviewed initial output and error reports for errors which could have resulted from misunderstanding of c&g format specifications or procedures. summary open communication chmmels and interdepartmental cooperation provided the source and means for producing a library information tool which could not have been produced by use of a single department's resources. the data base of local grant information is maintained by a campus administrative department and lent to the library for index extraction. project development time was considerably shortened by the donated time of computer center staff. the analysis and specification of requirements, and system implementation were provided by the library. departmental "perquisites" which had to be modified to allow a common project included the library's acceptance of unrevised "bibliographic" information (i.e., unedited names and titles), and the c&g office's release of an internal file for external use and interpretation. work has been completed to provide for inclusion of intramurally funded research projects in the index. data for these projects are provided by simplified card input records transcribed by the management services unit of the computer center from routinely generated transmission letters. the resulting index records remain completely independent of the c&g update system except for the use of campus "granting agency" codes added to the c&g table files. acknowledgments the virtual absence in this project of the usual irritat ions and energy-devouring aspects of

entries retrieved by use of trunca1'ed search keys 207 frederick g. kilgour, philip l. long, eugene b. liederman, and alan l. landgraf: the ohio college library center, columbus, ohio. an experiment testing utility of truncated search keys as inquiry terms in an on-line system was performed on a file of 16,792 title-only bibliographic entries. use of a 3,3 key yields eight or fewer entries 99.0% of the time. a previous paper ( 1) established that truncated derived search keys are efficient in retrieval of entries from a name-title catalog. this paper reports a similar investigation into the retrieval efficiency of truncated keys for extracting entries from an on-line, title-only catalog; it is assumed that entries retrieved would be displayed on an interactive terminal. earlier work by ruecking (2), nugent (3), kilgour (4), dolby (5), coe ( 6), and newman and buchinski ( 7) were investigations of search keys designed to retrieve bibliographic entries from magnetic tape files. the earlier paper in this series and the present paper investigate retrieval from on-line files in an interactive environment. similarly, the work of rothrock ( 8) inquired into the efficacy of derived truncated search keys for retrieving telephone directory entries from an on-line file. since the appearance of the previous paper, the ohio state university libraries have developed and activated a remote catalog access and circulation control system employing a truncated derived search key similar to those described in the earlier paper. however, osu adopted a 4,5 key consisting of the first four characters of the main entry and the first five characters of the title excluding initial articles and a few other nonsignificant words. whereas the osu system treats the name and title as a continuous string of characters, the experiments reported in this and the previous paper deal only with the first word in the name and title, articles always being excluded. 208 journal of library automation vol. 4/4 december, 1971 the bell system has also recently activated a large traffic experiment in the san francisco bay area. the master file in this system contains 1,300,000 directory entries. the system utilizes truncated derived keys like those investigated in the present experiments. materials and methods the file used in this experiment was described in the earlier paper ( 1), except that this experiment investigates the title-only entries. the same programs used in the name-title investigation were used in this experiment; the title-only entries were edited so that the first word of the title was placed in the name field and the .11emaining words in the title field. as was the case formerly, it was necessary to clean up the file. single word titles often carried in the second or title field such expressions as one year subscription or vol 16 1968. in addition there were spurious character strings that were not titles, and in such cases the entire entry was removed from the file. thereby, the original 17,066 title entries were reduced to 16,792. the truncated search keys derived from these title-only entries consist of the initial characters of the first word of the title and of the second word of the title. if there was no second word, blanks were employed. if either the first or second word contained fewer characters than the key to be derived, the key was left-justified and padded out with blanks. to obtain a comparison of the effectiveness of truncated research keys derived from title-only entries as related to first keys derived from nametitle entries, a name-title entry fil e of the same number of entries ( 16,792) was constructed. a series of random numbers larger than the number of entries in the original name-title file ( 132,808 ) was generated and one of the numbers was added to each of the 132,808 name-title entries in sequence. next the fil e was sorted by number so that a randomized file was obtained. then the first 16,792 name-title entries were selected. the same program analyzed keys d erived from this file. results table 1 presents the maximum number of entries to be expected in 99% of replies for the file of 16,792 title-only entries as well as for the nametitle file containing the same total of entries. for example, when a large number of random requests are put to the title-only file using a 3,3 search key, the prediction is that 99.0% of the time, eight or fewer replies will be returned. however, in the case of the name-title file , only two replies will be returned 99.3% of the time. the 3,3 key produced only thirteen replies ( .12% of the total number of 3,3 keys) containing twenty-one or more entries. the highest number of entries for a single reply for the 3,3 key was 235 ( "jou ,of" d erived from journal of ) . the next highest number of replies was 88 ("adv, in" for advances in ) . trun cated search keys j kilgour 209 table 1. maximum number of entries in 99% of replies

markov string of zero order, since the name string and title string are uncorrelated. however, the two words from which keys are derived in the title-only entry are first order markov strings, since they are consecutive words from the title string and are correlated. the consequence of these two circumstances on the effective ness of derived keys is clearly presented in table 1. the keys from name-title entries consistently produce fewer maximum entries per reply. therefore, it is desirable to derive keys from zero order markov strings wherever possible. the ohio state university libraries contain over two and a quarter million volumes, but on 9 february 1971 there were only 47,736 title-only main entries in the catalog. the file used in the present experiment is 35% of the size of the osu file. since 99% of the time the 3,3 key yields eight or fewer titles, it is clear that such a key will be adequate for retrieval for library on-line, title-only catalogs. the 3,3 key also posse sses the attractive quality of eliminating the majority of human misspe1ling as pointed out in the earlier paper ( 1). there remains, however, the unsolved problem of the efficient retrieval of such titles as those beginning with "journal of" and "advances in". it appears that it will be necessary to devise a special algorithm for those relatively few titles that produce excessively high numbers of entries in replies. in the previous investigation it was found that a 3,3 key yielded five or fewer replies 99.08% of the time from a fil e of 132,808 name-title entries. table 1 shows that for a file of only 16,792 entries the 3,3 key produces two or fewer replies 99.3% of the time . these two observations suggest that as a file of bibliographic entries increases, the maximum number of entries per reply does not increase in a one-to-one ratio, since the maximum 210 journal of library automation vol. 4/4 december, 1971 number of entries rose from two to five while the total size of the file increased from one to approximately eight. further research must be done in this area to determine the relative behavior of derived truncated keys as their associated file sizes vary. conclusion this experiment has produced evidence that a series of truncated search keys derived from a first order markov word string in a bibliographic description yields a higher number of maximum entries per reply than does a series derived from a zero order markov string. however, the results indicate that the technique is nonetheless sufficiently efficient for application to large on-line library catalogs. use of a 3,3 search key yields eight or fewer entries 99.0% of the time from a file of 16,792 title-only entries. acknowledgment this study was supported in part by national

june 2013 18 “the dilemma for the cultural heritage preservation community derives from the lag between immediate need and the long-term transformation of digital preservation expertise.” 1 introduction every day history is being made and recorded in digital form. every day, more and more digitally captured history disappears completely or becomes inaccessible due to obsolescence of hardware, software, and formats.2 although it has long been the focus of libraries and archives to retain, organize, and preserve information, these communities face a critical skills gap. 3 further, the typical library cannot support a true, trusted digital repository compliant with the open archival information system (oais) framework.4 until we have in place the infrastructure, expertise, and resources to distill critical information from the digital deluge and preserve it appropriately, what steps can those in the field take to help mitigate the loss of our cultural heritage? the very “scale of the digital landscape makes it clear that preservation is a process of triage.” 5 while educational systems across the country are scrambling to develop training programs to address the problem, it will be years, if ever, before every cultural heritage institution has at least one of these formally trained employees on staff. librarians and archivists already in place are wondering what they can do in the meantime. those on the front lines of this battlefront to save our cultural history need training. surrounded by content under digitization, digital content coming into special collections and archives, assisting content creators in their research and scholarship, these archivists and librarians need to know what they can do to prevent more critical loss. even if developing a preservation program is limited to ensuring the digital content survives long enough to be collected by some better-funded agency, capturing records in open standard interoperable technology neutral formats would help to ease later ingest of such content into a trusted digital repository.6 as molinaro has pointed out, those in the field need “the knowledge and skills to ensure that their projects and programs are well conceived, feasible, and have a solid sustainability plan.” 7 for those on the front lines, digital preservation education needs to be accessible, practical, and targeted to an audience that may have little technical expertise. since “resources for preservation are meager in small and medium-sized heritage organizations,” 8 such training needs to be free or as low-cost as possible. jody l. deridder (jlderidder@ua.edu) is head of digital services at the university of alabama libraries, tuscaloosa. mailto:jlderidder@ua.edu first aid training for those on the front lines | deridder 19 in an effort to address these needs, the library of congress established the digital preservation outreach & education (dpoe) train-the-trainer network.9 in six one-hour modules,10 this training provides a basic overview of the framework necessary to begin to develop a digital preservation program. the modules formed the basis for three well-attended aserl webinars in february 2012.11 attendee feedback after the webinars indicated a deep need for practical, detailed instruction for those in the field. this article reports on the results of a follow-up survey to identify the topics and types of materials most important to webinar attendees and their institutions for digital preservation, in the fall of 2012. approach the survey was open from october 2 until december 15, 2012. invitations to participate were sent to the following discussion lists: society of american archivists (saa) archives & archivists (a&a), saa preservation section discussion list, saa metadata and digital object round table discussion list, digital-curation (google group), digital library federation (dlf-announce), and the library of congress digital preservation and outreach (dpoe) general listserv. each invitation clarified that respondents need not be association of south eastern research libraries (aserl) members in order to attend the free webinars or to participate in the survey. the survey consisted of three questions, the first to determine the sources of digital content most important for respondents’ institutions to preserve, and the second to identify the topics of greatest concern to respondents themselves. for these two questions, respondents were asked to rate the options as: • extremely important • somewhat important • maybe of value • not important at all the first two questions are as follows: please rate the following sources of digital content in terms of importance for preservation at your institution: • born-digital institutional records • born-digital special collections materials • digitized collections • digital scholarly content (institutional repository or grey literature) • digital research data • web content • other please rate the following topics in terms of importance to you, for inclusion in future training webinars: information technology and libraries | june 2013 20 • how to inventory content to be managed for preservation • developing selection criteria, and setting the scope for what your institution commits to preserving • selecting storage options and number of copies • determining what metadata to capture and store • methods of preservation metadata extraction, creation, and storage • legal issues surrounding access, use, migration, and storage • selecting file formats for archiving • validating files and capturing checksums • monitoring status of files and media • file conversion and migration issues • business continuity planning • security and disaster planning at multiple levels of scope • self-assessment and external audits of your preservation implementation • developing your institution's preservation policy and planning team • planning for provision of access over time • other after each of these questions, respondents were provided a free text field in which to add additional entries related to the “other” entry. the last question on the survey asked respondents whether they are members of an aserl institution, since aserl is supporting this series of webinars. results of the 182 respondents, 37 (20.7 percent) self-identified as aserl members, 142 (79.3 percent) as non-aserl members, and three skipped the question. all respondents answered the first two queries. sources of digital content for the complete set of respondents, the top three types of material considered extremely important for preservation were born-digital special collections materials (65 percent, 117 respondents), born-digital institutional records (62.7 percent, 111 respondents), and digitized collections (61.2 percent, 109 respondents). digital scholarly content, digital research data, and web content trailed in importance, rated extremely important by only 37 percent (64 respondents), 33.9 percent (59 respondents), and 30.6 percent (52 respondents) respectively. in clarification, one respondent listed “born-digital correspondence (e-mail),” another listed “state government digital archival records,” a third asked for instructions for use of “kodak’s new asset protection film for preservation of moving and still images,” and one specified that by “special collections” she meant “audiovisual.” first aid training for those on the front lines | deridder 21 the concern for a/v materials was echoed by some of the 8 respondents suggesting other content as extremely important: “born-digital moving image preservation” (an aserl respondent), “best practices for preservation of different audio and video formats” (also an aserl respondent), “born digital photographs and video of college events,” and a request for an “audio digitization workshop.” additional “other” entries were copyright pitfalls, data security, and “very practical steps that very small institutions can take to preserve their digital materials (e.g. how to check digital integrity, and how often, selection of storage media, and creation of a ‘dark archive’).” one aserl respondent indicated that she did not rate “born digital” institutional and special collections materials as extremely important for preservation only because her institution does not yet have a system set up for these, nor do they yet collect many born-digital special collections. she clarified that she does think this is extremely important despite the seeming lack of interest on the part of her institution. figure 1. results for all survey respondents indicating sources of digital content of importance for preservation at their institution. information technology and libraries | june 2013 22 in comparing the responses to the first question by whether the respondents self-identified as members of an aserl institution (37 respondents as opposed to 142), those who did considered born-digital special collections materials far more important (73 percent, 27 respondents) than non-aserl respondents (62.9 percent, 88 respondents), but this still was rated most important by both groups. second for aserl respondents was digitized collections (69.4 percent, 25 respondents) whereas born-digital institutional records held second place for non-aserl respondents (62 percent, 85 respondents). third and fourth-ranked material sources for aserl respondents were born-digital institutional records (64.9 percent, 24 respondents) and digital scholarly content (63.9 percent, 23 respondents); digital research data only rated 52.8 percent (19 respondents). non-aserl respondents considered digitized collections the third most important source of digital content for preservation (59.7 percent, 83 respondents), and this group of respondents was far less concerned with digital scholarly content (29.9 percent, 40 respondents) or digital research data (29.6 percent, 40 respondents) than the aserl respondents. web content ranked lowest for both groups: 29.4 percent (10) aserl respondents and 30.6 percent (41) nonaserl respondents considered this content extremely important. figure 2. results for aserl survey respondents indicating sources of digital content of importance for preservation at their institution. first aid training for those on the front lines | deridder 23 figure 3. results for non-aserl survey respondents indicating sources of digital content of importance for preservation at their institution. perhaps most surprising was that 20 non-aserl respondents (14.8 percent) rated digital research data as “not important at all” for preservation at their institutions, but this may be reflective of their type of institution. museums and historical societies, non-research institutions, and government agencies likely are not concerned with research data; this theory seems to be supported by the 12.7 percent (17) non-aserl respondents who rated digital scholarly content as “not important at all.” in comparison, only one aserl respondent (2.8 percent) indicated that research data had no importance to his institution for preservation (0 for digital scholarly content). this may simply reflect a lack of awareness of current issues on the part of the respondent. topics of interest both groups of respondents agreed on the three most important topics for future training webinars. “methods of preservation metadata extraction, creation and storage” led the way with 77.3 percent (140 respondents: 70.3 percent or 26 aserl and 79.4 percent or 112 non-aserl) information technology and libraries | june 2013 24 listing this as extremely important. next was “determining what metadata to capture and store” (68 percent, 96 respondents: 62.2 percent or 23 aserl and 66.7 percent or 120 non-aserl). the third most important topic is “planning for provision of access over time” at 65.4 percent (117 respondents: 1.1 percent or 22 aserl and 65.7 percent or 92 non-aserl). figure 4. results for all survey respondents indicating topics of importance to them, for future training webinars. fourth in importance overall was “file conversion and migration issues” (58.8 percent, 107 respondents: 54.1 percent or 20 aserl and 60.6 percent or 86 non-aserl), though the aserl respondents thought this topic was slightly less critical than “developing selection criteria, and setting the scope for what your institution commits to preserving” (56.8 percent, 21 respondents as opposed to 49.6 percent or 70 non-aserl respondents; overall percentage 51.9 percent, 94 respondents). close in relative importance were “validating files and capturing checksums” (53.9 percent, 97 respondents), “monitoring status of files and media” (52.8 percent, 95 respondents), and “developing your institution’s preservation policy and planning team” (51.1 percent, 92 first aid training for those on the front lines | deridder 25 respondents). interestingly, however, “validating files and capturing checksums” is far more important to non-aserl respondents (53.6 percent, 75 respondents) than those from aserl institutions (only 37.8 percent, 14 respondents). “legal issues surrounding access, use, migration and storage” is a more important topic for aserl respondents (51.4 percent, 19 respondents) than non-aserl (42.8 percent, 77 respondents), and aserl respondents were more concerned (37.8 percent, 14 respondents) than non-aserl (33.1 percent, 46 respondents) with “selfassessment and external audits.” additionally, “selecting file formats for archiving” and “selecting storage options and number of copies” is more important for non-aserl (47.5 percent, 67 respondents and 47.9 percent, 67 respondents) than aserl respondents (35.1 percent, 13 respondents and 32.4 percent, 12 respondents, respectively). figure 5. results for aserl survey respondents indicating topics of importance to them, for future training webinars. “security and disaster planning” was ranked extremely important by only 32.6 percent (45) respondents overall, followed by “business continuity planning” at only 29.2 percent (40) respondents. the latter may reflect a lack of widespread awareness of just how critical the loss of information technology and libraries | june 2013 26 a single key employee can be, especially in smaller institutions. it also seems clear that there’s a level of complacency or sense of security about our ephemeral digital content that may be in error. then again, it is quite possible that the respondents are not administrators and feel they do not have the power in their organizations to address such issues. figure 6. results for non-aserl survey respondents indicating topics of importance to them, for future training webinars. additional topics considered extremely important to respondents are as follows, listed in the free text area (the last four by aserl members): • "clean" work station setup—hardware & software for ingest, virus scan, checksum, disk image, metadata, conversion, etc. • integrating tools into your workflow. there is a need to address the nuts and bolts for those of us that are further along in determining the metadata required to capture, selection criteria, and asset audit and preservation policy. first aid training for those on the front lines | deridder 27 • methods for providing researchers access to born digital content (not necessarily online, could be just in-house). • strategies for locating digital assets on physical media in large collections that have been using mplp [“more product, less process”] for decades. • format determination and successful migration or emulation. • staff diversity and training. • how to validate files, migrate files, and which born-digital institutional files our special collections needs to be preserving. • creating and maintaining effective organizational models for digital preservation (i.e. collaboration with central it and/or external vendors, etc.). • case studies of digital preservation, establishing workflow of digital preservation. • web archiving (best practices, alternatives to archive-it, methods of selection, etc.). • one (non-aserl) respondent said it was “somewhat important” to include the topic of “trends for field, future outlook.” conclusions the results from this survey are clear: free or low-cost training needs to focus immediately on preservation of born-digital special collections materials, born-digital institutional records, and digitized collections. the topics of prime importance to respondents were “methods of preservation metadata extraction, creation and storage,” “determining what metadata to capture and store,” and “planning for provision of access over time.” the variations in ratings between respondents from self-identifying as aserl members versus non-aserl members indicates that the needs of those in research libraries differs somewhat from that of cultural heritage institutions in the field dealing with “the long tail” of digital content. 12 future training may need to target these differing audiences appropriately to ensure these needs are met. additionally, administrators need to be addressed as a unique audience in order to focus on the requirements for addressing “security and disaster planning” and “business continuity planning,” as these critical areas need to be developed by those in management positions. future surveys of this nature should include a component to determine the level of technical expertise and support the respondents have, as well as a measure of their position or power in the administrative hierarchy. continued surveys would be extremely helpful in ensuring that available educational options meet the needs of librarians and archivists in the field. as molinaro has pointed out, “getting the right information in the right hands at the right time is a problem that has plagued the library community for decades.” 13 now is the time to develop free, openly available, practical digital preservation training for those on the front lines, if we are to retain critical cultural heritage materials which are only available in digital form. for them to effectively perform necessary triage on incoming digital content, they must be trained in “first aid.” our history is at stake. information technology and libraries | june 2013 28 references 1. paul conway, “preservation in the age of google: digitization, digital preservation, and

http://www.aserl.org/archive/ 104 information technology and libraries | september 2010 development of such a mediation mechanism calls for an empirical assessment of various issues surrounding metadata-creation practices. the critical issues concerning metadata practices across distributed digital collections have been relatively unexplored. while examining learning objects and e-prints communities of practice, barton, currier, and hey point out the lack of formal investigation of the metadatacreation process.2 as will be discussed in the following section, some researchers have begun to assess the current state of descriptive practices, metadata schemata, and content standards. however, the literature has not yet developed to a point where it affords a comprehensive picture. given the propagation of metadata projects, it is important to continue to track changes in metadata-creation practices while they are still in constant flux. such efforts are essential for adding new perspectives to digital library research and practices in an environment where metadata best practices are being actively sought after to aid in the creation and management of high-quality digital collections. this study examines the prevailing current state of metadata-creation practices in digital repositories, collections, and libraries, which may include both digitized and born-digital resources. using nationwide survey data, mostly drawn from the community of cataloging and metadata professionals, we seek to investigate issues in creating descriptive metadata elements, using controlled vocabularies for subject access, and propagating metadata and metadata guidelines beyond local environments. we will address the following research questions: 1. which metadata schema(ta) and content standard(s) are employed in individual digital repositories and collections? 2. which controlled vocabulary schema(ta) are used to facilitate subject access? 3. what criteria are applied in selecting metadata and controlled-vocabulary schema(ta)? 4. to what extent are mechanisms for exposing and sharing metadata integrated into current metadatacreation practices? in this article, we first review recent studies relating to current metadata-creation practices across digital collections. then we present the survey method employed to conduct this study, the general characteristics of survey participants, and the validity of the collected data, followed by the study results. we report on how metadata and controlled vocabulary schema(ta) are being used across institutions, and we present a data analysis of current metadata-creation practices. the final section summarizes the study and presents some suggestions for future studies. this study explores the current state of metadata-creation practices across digital repositories and collections by using data collected from a nationwide survey of mostly cataloging and metadata professionals. results show that marc, aacr2, and lcsh are the most widely used metadata schema, content standard, and subjectcontrolled vocabulary, respectively. dublin core (dc) is the second most widely used metadata schema, followed by ead, mods, vra, and tei. qualified dc’s wider use vis-à-vis unqualified dc (40.6 percent versus 25.4 percent) is noteworthy. the leading criteria in selecting metadata and controlled-vocabulary schemata are collection-specific considerations, such as the types of resources, nature of the collection, and needs of primary users and communities. existing technological infrastructure and staff expertise also are significant factors contributing to the current use of metadata schemata and controlled vocabularies for subject access across distributed digital repositories and collections. metadata interoperability remains a major challenge. there is a lack of exposure of locally created metadata and metadata guidelines beyond the local environments. homegrown locally added metadata elements may also hinder metadata interoperability across digital repositories and collections when there is a lack of sharable mechanisms for locally defined extensions and variants. m etadata is an essential building block in facilitating effective resource discovery, access, and sharing across ever-growing distributed digital collections. quality metadata is becoming critical in a networked world in which metadata interoperability is among the top challenges faced by digital libraries. however, there is no common data model that cataloging and metadata professionals can readily reference as a mediation mechanism during the processes of descriptive metadata creation and controlled vocabulary schemata application for subject description.1 the jung-ran park (jung-ran.park@ischool.drexel.edu) is assistant professor, college of information science and technology, drexel university, philadelphia, and yuji tosaka (tosaka@tcnj.edu) is cataloging/metadata librarian, tcnj library, the college of new jersey, ewing, new jersey. jung-ran park and yuji tosaka metadata creation practices in digital repositories and collections: schemata, selection criteria, and interoperability metadata creation practices in digital repositories and collections | park and tosaka 105 possible increase in the use of locally developed schemata as many projects added new types of nontextual digital objects that could not be adequately described by existing metadata schemata.6 there is a lack of research concerning the current use of content standards; however, it is reasonable to suspect that content-standards use exhibits patterns similar to that of metadata because of their often close association with particular metadata schemata. the oclc rlg survey reveals that anglo-american cataloguing rules, 2nd edition (aacr2)—the traditional cataloging rule that has most often been used in conjunction with marc—is the most widely used content standard (81 percent). aacr2 is followed by describing archives: a content standard (dacs) with 42 percent; descriptive cataloging of rare materials with 33 percent; archives, personal papers, manuscripts (appm) with 25 percent; and cataloging cultural objects (cco) with 21 percent.7 in the same way as metadata schemata, there appears to be a concentration of a few controlled vocabulary schemata at research institutions. ma’s arl survey, for example, shows that the library of congress subject headings (lcsh) and name authority file (naf) were used by most survey respondents (96 percent and 88 percent, respectively). these two predominantly adopted vocabularies are followed by several domain-specific vocabularies, such as art and architecture thesaurus (aat), library of congress thesaurus for graphical materials (tgm) i and ii, getty thesaurus of geographic names (tgn), and the getty union list of artists names (ulan), which were used by between 30 percent to more than 60 percent of respondents.8 the oclc rlg survey reports similar results; however, nearly half of the oclc rlg survey respondents (n = 9) indicated that they had also built and maintained one or more locally developed thesauri.9 while creating and sharing information about local metadata implementations is an important step toward increased interoperability, recent studies tend to paint a grim picture of current local documentation practices and open accessibility. in a nationwide study of institutional repositories in u.s. academic libraries, markey et al. found that only 61.3 percent of the 446 survey participants with operational institutional repositories had implemented policies for metadata schemata and authorized metadata creators.10 the oclc rlg survey also highlights limited collaboration and sharing of the metadata guidelines both within and across the institutions. it finds that even when there are multiple units creating metadata within the same institution, metadata-creation guidelines often are unlikely to be shared (28 percent do not share; 53 percent sometimes share).11 a mixed result is reported on the exposure of metadata to outside service providers. in an arl survey, the university of houston libraries institutional repository ■■ literature review as evinced by the principles and practices of bibliographic control through shared cataloging, successful resource access and sharing in the networked environment demands semantic interoperability based on accurate, complete, and consistent resource description. the recent survey by ma finds that the open archives initiative protocol for metadata harvesting (oai-pmh) and metadata crosswalks have been adopted by 83 percent and 73 percent of respondents, respectively. even though the sample comes only from sixty-eight association of research libraries (arl) member libraries, and the figures thus may be skewed higher than those of the entire population of academic libraries, there is little doubt that interoperability is a critical issue given the rapid proliferation of metadata schemata throughout digital libraries.3 while there is a variety of metadata schemata currently in use for organizing digital collections, only a few of them are widely used in digital repositories. in her arl survey, ma reports that the marc format is the most widely used metadata schema (91 percent), followed by encoded archival description (ead) (84 percent), unqualified dublin core (dc) (78 percent), and qualified dc (67 percent).4 similarly, a 2007 member survey by oclc research libraries group (rlg) programs gathered information from eighteen major research libraries and cultural heritage institutions and also found that marc is the most widely used scheme (65 percent), followed by ead (43 percent), unqualified dc (30 percent), and qualified dc (29 percent). the different levels of use reported by these studies are probably due to different sample sizes and compositions, but results nonetheless suggest that metadata use at research institutions tends to rely on a small number of major schemata.5 there may in fact be much greater diversity in metadata use patterns when the scope is expanded to include both research and nonresearch institutions. palmer, zavalina, and mustafoff, for example, tracked trends from 2003 through 2006 in metadata selection and application practices at more than 160 digital collections developed through institute of museum and library services grants. they found that despite perceived limitations, use of dc is the most widespread, with more than half of the digital collections using it alone or in combination with other schemata. marc ranks second, with nearly 30 percent using it alone or in combination. the authors found that the choice of metadata schema is largely influenced by practices at peer institutions and compatibility with a content management system. what is most striking, however, is the finding that locally developed schemata are used as often as marc. there is a decline in the percentage of digital projects using multiple metadata schemata (from 53 percent to 38 percent). yet the authors also saw a 106 information technology and libraries | september 2010 ■■ method the objective of the research reported in this paper is to examine the current state of metadata-creation practices in terms of the creation of descriptive metadata elements, the use of controlled vocabularies for subject access, and the exposure of metadata and metadata guidelines beyond local environments. we conducted a web survey using websurveyor (now vovici: http://www.vovici .com). the survey included both structured and openended questions. it was extensively reviewed by members of an advisory board—a group of three experts in the field—and it was pilot-tested prior to being officially launched. the survey included many multiple-response questions that called for respondents to check all applicable answers. we recruited participants through survey invitation messages and subsequent reminders to the electronic mailing lists of communities of metadata and cataloging professionals. table 1 shows the mailing lists employed for the study. we also sent out individual invitations and distributed flyers to selected metadata and cataloging sessions during the 2008 ala midwinter meeting, held that year in philadelphia. the survey attracted a large number of initial participants (n = 1,371), but during the sixty-two days from august 6 to october 6, 2008, we only received 303 completed responses via the survey management system. we suspect that the high incompletion rate (77.9 percent) stems from the fact that the subject matter may have been outside the scope of many participants’ job responsibilities. the length of the survey may also have been a factor in the incompletion rate. the profiles of respondents’ job titles (see table 2) task force found that exposing metadata to oai-pmh service providers is an established practice used by nearly 90 percent of the respondents.12 ma’s arl survey also reports the wide adoption of oai-pmh (83 percent). these results underscore the virtual consensus on the critical importance of exposing metadata to achieve interoperability and make locally created metadata useful across distributed digital repositories and collections.13 by contrast, the oclc rlg survey shows that only one-tenth of the respondents stated that all non-marc metadata is exposed to oai harvesters, while 30 percent indicated that only some of it was available. the prominent theme revealed by the oclc rlg survey is an “inward focus” in current metadata practices, marked by the “use of local tools to reach a generally local audience.”14 in summary, recent studies show that the current practice of metadata creation is problematic due to the lack of a mechanism for integrating various types of metadata schemata, content standards, and controlled vocabularies in ways that promote an optimal level of interoperability across digital collections and repositories. the problems are exacerbated in an environment where many institutions lack local documentation delineating the metadata-creation process. at the same time, researchers have only recently begun studying these issues, and the body of literature is at an incipient stage. the research that was done often targeted different populations, and sample sizes were different (some very small). in some cases the literature exhibits contradictory findings about issues surrounding metadata practices, increasing the difficulty in understanding the current state of metadata creation. this points out the need for further research of current metadata-creation practice. table 1. electronic mailing lists for the survey electronic mailing lists

most of the individuals who completed the survey engage professionally in activities directly relevant to the research objectives, such as descriptive and subject cataloging, metadata creation and management, authority control, nonprint and special material cataloging, electronic resource and digital project management, and integrated library system (ils) management. although the largest number of participants (135, or 44.6 percent) chose the “other” category regarding their job title (see table 2), it is reasonable to assume that the vast majority can be categorized as cataloging and metadata professionals.15 most job titles given as “other” are associated with one of the professional activities listed in table 4. thus it is reasonable to assume that the respondents are in an appropriate position to provide first-hand, accurate information about the current state of metadata creation in their institutions. concerning the institutional background of participants, of the 303 survey participants, fewer than half (121, or 39.9 percent) provided institutional information. we believe that this is mostly due to the fact that the question was optional, following a suggestion from the institutional review board at drexel university. of those that provided their institutional background, the majority (75.2 percent) are from academic libraries, followed by participants from

(please check all that apply) metadata creation practices in digital repositories and collections | park and tosaka 109 custom metadata elements derives from the imperative to accommodate the perceived needs of local collections and users, as indicated by the two most common responses: (1) “to reflect the nature of local collections/resources” (76.9 percent) and (2) “to reflect the characteristics of target audience/community of local collections” (58.3 percent). local conditions were also cited from institutional and technical standpoints. many institutions (34.3 percent) follow existing local practices for cataloging and metadata creation while other institutions (18.5 percent) are making homegrown metadata additions because of constraints imposed by their local systems. table 6 summarizes the most frequently used controlled vocabulary schematas by resource type. by far the most widely used schema across all resource types was lcsh. the preeminence of lcsh evinces the critical role that it plays as the de facto form of controlled vocabulary for subject description. library of congress classification (lcc) was the second choice for all resource types other than images, cultural objects, and archives. for digital collections of these resource types and digitized resources, aat was the second most used controlled vocabulary, a fact that reflects its purpose as a domain-specific terminology used for describing works of art, architecture, visual resources, material culture, and archival materials. while traditional metadata schemata, content standards, and controlled vocabularies such as marc, aacr2, and lcsh clearly were preeminent in the majority of the respondents’ institutions, current metadata creation in digital repositories and collections faces new challenges from the enormous volume of online and digital resources.19 approximately one-third of the respondents’ institutions (33.8 percent) were meeting this challenge with tools for semiautomatic metadata generation. yet a majority of respondents (52.5 percent) indicated that their institutions did not use any such tools for metadata creation and management. this result seems to contrast with ma’s finding that automatic metadata generation was used in some capacity in nearly by oclc rlg programs (as described in “literature review” on page 105).16 in these surveys, unqualified dc was more frequently cited than qualified dc. one possible explanation of this less frequent use of unqualified dc may lie in the limitations of unqualified dc metadata semantics. survey respondents also reported on problems using dc metadata, which were mostly caused by semantic ambiguities and semantic overlaps of certain dc metadata elements.17 limitations and issues of unqualified dc metadata semantics are discussed in depth in park’s study.18 in light of these results, examining trends of qualified dc use in a future study would be interesting. despite the wide variety of schemata reported in use, there seemed to be an inclination to use only one or two metadata schemata for resource description. as shown in table 5, the majority of the respondents’ institutions (53.6 percent) used only one schema for metadata creation, while approximately 37 percent used two or three schemata (26.2 percent and 10.3 percent, respectively). the institutions using more than three schemata during the metadata-creation processes comprised only 9.9 percent of the respondents. turning to content standards (see figure 3), we found that aacr2 was the most widely used standard, indicated by 84.5 percent of respondents. this high percentage clearly reflects the continuing preeminence of marc as the metadata schema of choice for digital collections. dc application profiles also showed a large user base, indicated by more than one-third of respondents (37.0 percent). more than one quarter of the respondents (28.4 percent) used ead application guidelines as developed by the society of american archivists and the library of congress, while 10.6 percent used rlg best practice guidelines for encoded archival description (2002). about one quarter (25.7 percent) indicated dacs as their content standard. homegrown standards and guidelines are local application profiles that clarify existing content standards and specify how values for metadata elements are selected and represented to meet the requirements of a particular context. as shown in the results on metadata schemata, it is noteworthy that homegrown content standards and guidelines constituted one of the major choices of participants, indicated by more than one-fifth of the institutions (22.1 percent). almost two-fifths of the survey participants (38 percent) also reported that they add homegrown metadata elements to a given metadata schema. slightly less than half of the participants (47.2 percent) indicated otherwise. the local practice of creating homegrown content guidelines and metadata elements during the metadatacreation process deserves a separate study; this study only briefly touches on the basis for locally added custom metadata elements. the motivation to create table 5.

(please check all that apply) 110 information technology and libraries | september 2010 criteria for selecting metadata and controlled vocabulary schemata what are the factors that have shaped the current state of metadata-creation practices reported thus far? in this section, we turn our attention to constraints that affect decision making at institutions in the selection of metadata and controlled vocabulary schemata for subject description. figure 4 presents the percentage of different metadata schemata selection criteria described by survey participants. first, collection-specific considerations clearly played a major role in the selection. the most frequently cited reason was “types of resources” (60.4 percent). this response reflects the fact that a large number of metadata schemata have been developed, often with wide variation in content and format, to better handle particular two-thirds of arl libraries.20 because semiautomatic metadata application is reported in-depth in a separate study, we only briefly sketch the topic here.21 the semiautomatic metadata application tools used in the respondents’ digital repositories and collections can be classified into five categories of common characteristics: (1) metadata format conversion, (2) templates and editors for metadata creation, (3) automatic metadata creation, (4) library system for bibliographic and authority control, and (5) metadata harvesting and importing tools. as table 7 illustrates, among those institutions that have introduced semiautomatic metadata generation tools, “metadata format conversion” (38.6 percent) and “templates and editors for metadata creation” (27 percent) are the two most frequently cited tools. figure 3. content standards used (multiple responses) survey question: what content standard(s) and/or guidelines do you and your fellow catalogers/metadata librarians use? (please check all that apply) metadata creation practices in digital repositories and collections | park and tosaka 111 job responsibility, “expertise of staff” (44.2 percent) and “integrated library system” (39.9 percent) appeared to highlight the key role that marc continues to play in the metadata-creation process for digital collections (see figure 2). “budget” also appeared to be an important factor in metadata selection (17.2 percent), showing that funding levels played a considerable role in metadata decisions. types of information resources. the primary factor in selecting metadata schemata is their suitability for describing the most common type of resources handled by the survey participants. the second and third most common criteria, “target users/ audience” (49.8 percent) and “subject matters of resources” (46.9 percent), also seem to reflect how domain-specific metadata schemata are applied. in making decisions on metadata schemata, respondents weighed materials in particular subject areas (e.g., art, education, and geography) and the needs of particular communities of practice as their primary users and audiences. however, existing technological infrastructure and resource constraints also determine options. given the prominence of general library cataloging as a primary table 6. the most frequently used controlled vocabulary schema(s) by resource type (multiple responses) lcsh lcc ddc aat tgm ulan tgn other text 79.5% (241) 35.6% (108) 16.8% (51) 10.2% (31) 6.9% (21) 3.6% (11) 5.0% (15) 14.2% (43) audiovisual materials 67.3% (204) 25.1% (76) 12.9% (39) 9.2% (28) 8.6% (26) 4.0% (12) 5.0% (15) 14.5% (44) cartographic materials 44.9% (136) 17.5% (53) 7.3% (22) 5.0% (15) 4.3% (13) 1.3% (4) 4.3% (13) 6.3% (19) images 43.2% (131) 11.9% (36) 5.6% (17) 25.7% (78) 20.1% (61) 9.9% (30) 10.6% (32) 11.2% (34) cultural objects (e.g., museum objects) 20.1% (61) 7.3% (22) 4.3% (13) 13.2% (40) 6.3% (19) 4.6% (14) 3.0% (9) 7.9% (24) archives 44.2% (134) 11.6% (35) 6.3% (19) 11.9% (36) 6.6% (20) 3.0% (9) 2.6% (8) 12.2% (37) electronic resources 60.7% (184) 23.4% (71) 8.6% (26) 5.3% (16) 3.6% (11) 1.7% (5) 3.0% (9) 14.2% (43) digitized resources 51.8% (157) 15.5% (47) 5.0% (15) 15.5% (47) 10.2% (31) 6.6% (20) 7.6% (23) 15.2% (46) born-digital resources 43.9% (133) 13.5% (41) 5.6% (17) 8.3% (25) 7.3% (22) 4.3% (13) 4.6% (14) 13.9% (42) survey question: which controlled vocabulary schema(s) do you and your fellow catalogers/metadata librarians use most?

(please check all that apply) metadata creation practices in digital repositories and collections | park and tosaka 113 for search engines and 63.2 percent for oai harvesters), a result that may be interpreted as a tendency to create metadata primarily for local audiences. why do many institutions fail to make their locally created metadata available to other institutions despite wide consensus on the importance of metadata sharing in a networked world? responses from those institutions exposing none or not all of their metadata (see table 8) reveal that financial, personnel, and technical issues are major hindrances in promoting the exposure of metadata outside the immediate local environment. some institutions are not confident that their current metadata practices are able to satisfy the technical requirements for producing standards-based interoperable metadata. another reason frequently mentioned is copyright concerns about limited-access materials. yet some respondents simply do not see any merit to exposing their item-level metadata, citing its relative uselessness for resource discovery outside their institutions. as stated earlier, the practice of adding homegrown metadata elements seems common among many institutions. while locally created metadata elements accommodate local needs and requirements, they may also hinder metadata interoperability across digital repositories and collections if mechanisms for finding information about such locally defined extensions and variants are absent. homegrown metadata guidelines document local data models and function as an essential mechanism for metadata creation and quality assurance within and across digital repositories and collections.23 in this regard, it is essential to examine locally created metadata guidelines and best practices.24 however, the results of the survey analysis evince that the vast majority of institutions (72.0 percent) provided no public access to local application profiles on their websites while only 19.6 percent of respondents’ institutions made them available online to the public. ■■ conclusion metadata plays an essential role in managing, organizing, and searching for information resources. in the networked existing system features for authority control and controlled vocabulary searching, as exhibited by 17.2 percent of responses for “digital collection/or asset management software.” exposing metadata and metadata guidelines beyond local environments metadata interoperability across distributed digital repositories and collections is fast becoming a major issue.22 the proliferation of open-source and commercial digital library platforms using a variety of metadata schemata has implications on the librarians’ ability to create shareable and interoperable metadata beyond the local environment. to what extent are mechanisms for sharing metadata integrated into the current metadata-creation practices described by the respondents? figure 6 summarizes the responses concerning the uses of three major mechanisms for metadata exposure. approximately half of respondents exposed at least some of their metadata to search engines (52.8 percent) and union catalogs such as oclc worldcat (50.6 percent). more than one-third of the respondents exposed all or some of their metadata through oai harvesters (36.8 percent). about half or more of the respondents either did not expose their metadata or were not sure about the current operations at their institutions (e.g., 47.2 percent figure 6. mechanism to expose metadata (multiple responses) survey question: do you/your organization expose your metadata to oai (open archives initiative) harvesters, union catalogs or search engines? 114 information technology and libraries | september 2010 the dc metadata schema is the second most widely employed according to this study, with qualified dc used by 40.6 percent of responding institutions and unqualified dc used by 25.4 percent. ead is another frequently cited schema (31.7 percent), followed by mods (17.8 percent), vra (14.9 percent), and tei (12.5 percent). a trend of qualified dc being used (40.6 percent) more often than unqualified dc (25.4 percent) is noteworthy. one possible explanation of this trend may be derived from the fact that semantic ambiguities and overlaps in some of the unqualified dc elements interfere with use in resource description.25 given the earlier surveys reporting the higher use of unqualified dc over qualified dc, more in-depth examination of their use trends may be an important avenue for future studies. despite active research and promising results obtained from some experimental tools, practical applications of semiautomatic metadata generation have been incorporated into the metadata-creation processes by only one-third of survey participants. the leading criteria in selecting metadata and controlled vocabulary schemata are derived from collection-specific considerations of the type of resources, the nature of the collections, and the needs of primary users and communities. existing technological infrastructure, encompassing digital collection or asset management software, archival management software, institutional repository software, integrated library systems, and union catalogs also greatly influence the selection process. the skills and knowledge of metadata professionals and the expertise of staff also are significant factors in understanding current practices in the use of metadata schemata and controlled vocabularies for subject access across distributed digital repositories and collections. the survey responses reveal that metadata interoperability remains a challenge in the current networked environment despite growing awareness of its importance. for half of the survey respondents, exposing metadata to the service providers, such as oai harvesters, union catalogs, and search engines, does not seem to be a high priority because of local financial, personnel, and technical constraints. locally created metadata elements are added in many digital repositories and collections in large part to meet local descriptive needs and serve the target user community. while locally created metadata elements accommodate local needs, they may also hinder metadata interoperability across digital repositories and collections when shareable mechanisms are not in place for such locally defined extensions and variants. locally created metadata guidelines and application profiles are essential for metadata creation and quality assurance; however, most custom content guidelines and best practices (72 percent) are not made publicly available. the lack of a mechanism to facilitate public access to local application profiles and metadata guidelines may environment, the enormous volume of online and digital resources creates an impending research need to evaluate the issues surrounding the metadata-creation process and the employment of controlled vocabulary schemata across ever-growing distributed digital repositories and collections. in this paper we explored the current status of metadata-creation practices through an examination of survey responses drawn mostly from cataloging and metadata professionals (see tables 2, 3, and 4). the results of the study indicate that current metadata practices still do not create conditions for interoperability. despite the proliferation of newer metadata schemata, the survey responses showed that marc currently remains the most widely used schema for providing resource description and access in digital repositories, collections, and libraries. the continuing predominance of marc goes hand-in-hand with the use of aacr2 as the primary content standard for selecting and representing data values for descriptive metadata elements. lcsh is used as the de facto controlled vocabulary schema for providing subject access in all types of digital repositories and collections, while domain-specific subject terminologies such as aat are applied at significantly higher rates in digital repositories handling nonprint resources such as images, cultural objects, and archival materials. table 8. sample reasons for not exposing metadata not all our metadata conforms to standards required not all our metadata is oai compliant lack of expertise and time and money to

societal issues that have also filled my news feed. i spend a lot of time thinking and worrying about what their impact will be on our work and our institutions, how it impacts me and the people i work with personally, and what role core may play for many of us in the future. i imagine all of us are thinking about health and safety. we are all balancing those parts of ourselves that want to aid, to help, to teach and guide with the parts of ourselves that are anxious and scared. many of us have responsibilities where we need to protect our loved ones and ourselves. we are seeing the health and safety of our bipoc colleagues disproportionately harmed. balancing our crucial role within our communities is complicated and there are no right answers. i imagine many of us have been spending a lot of time thinking about money, whether it be personal concerns, institutional and organizational concerns, or their intersection point. we’re thinking a lot more about where our money comes from, how it is invested, how we pay for things, how we prioritize paying for things, who decides what gets purchased, and whose voice gets centered when we make that purchase. we’re thinking carefully about the institutions and infrastructures that have existed and how they will look different and should be different in a post-covid landscape. i imagine most of us are thinking about societal connections. we are interacting with our professional colleagues differently, and many of us are, perhaps for the first time, perceiving the deep imbalances that permeate our personal, social, and professional lives. we are all trying to figure out how to do the work we need to do when we are uncomfortable and the world is uncertain and the demands for change are coming from all angles and in a variety of forms. lita remained my professional home through the years because i found it to be a place where no matter who you were or where you worked, there was a place for you. that feeling of connection is so vital to all of us, pandemic and social unrest or not. knowing there is a network i can depend on to be there when i’m working through the difficult and uncomfortable makes the work just a little bit easier and significantly more meaningful. our professional organizations and affiliations have the ability to be an anchor in uncertain times whether through a change in career, a financial crisis, an environmental catastrophe, or a global health emergency. on august 31, 2020, lita officially dissolved and on september 1, our home became core. at our last lita board meeting, margaret heller and amanda l. goodman presented a history of lita. mailto:evviva@gmail.com http://hdl.handle.net/11213/14823 information technology and libraries september 2020 in the middle of difficulty lies opportunity | weinraub lajoie 2 what became clear to me in the retelling is that this is not lita’s first reorganization. nor is it our second or our third. llama, lita, and alcts have always been dancing with each other. our merger is an acknowledgement that we “...play a central role in every library, shaping the future of the profession by striking a balance between maintenance and innovation, process and progress, collaboration and leading.” collectively, we have had a year that is beyond comprehension—it has been filled with loss, anger, frustration, grief, anxiety, depression, horror...we have all been weathering the same storm, but our ships are not all equally prepared for the task laid ahead of them. that has been, for so many of us, the hardest part of all of this. we may have always known that inequities existed, that the system was structured to make sure that some folks were never able to get access to the better goods and services, but for many, this pandemic is the first time we have had those systemic inequities held up to our noses and been asked, “what are you going to do to change this?” balancing those priorities will require us to lean on our professional networks and organizations to be more and to do more. i believe that together, we can make core stand up to that challenge. it has been an honor to serve as the last lita president. for the brief time i have served, to have the chance to hold an office so many people i truly admire have held...it is a legacy i am proud to have had a moment to uphold. i am gratified to transition lita into a partnership that will take all that we have loved about lita and make something new, something core. https://core.ala.org/our-mission-vision-and-values/ https://core.ala.org/our-mission-vision-and-values/ https://core.ala.org/our-mission-vision-and-values/ president’s message: ux thinking and the lita member experience rachel vacek information technologies and libraries | september 1014 1 my mind has been occupied lately with user experience (ux) thinking in both the web world and in the physical world around me. i manage a web services department in an academic library, and it’s my department’s responsibility to contemplate how best to present website content so students can easily search for the articles they are looking for, or so faculty can quickly navigate to their favorite database. in addition to making these tasks easy and efficient, we want to make sure that users feel good about their accomplishments. my department has to ensure that the other systems and services that are integrated throughout the site are located in meaningful places and can be used at the point of need. additionally, the site’s graphic and interaction design must not only contribute to but also enhance the overall user experience. we care about usability, graphic design, and the user interfaces of our library’s web presence, but these are just subsets of the larger ux picture. for example, a site can have a great user interface and design, but if a user can’t get to the actual information she is looking for, the overall experience is less than desirable. jesse james garrett is considered to be one of the founding fathers of user-centered design, the creator of the pivotal diagram defining the elements of user experience, and author of book, the elements of user experience. he believes that “experience design is the design of anything, independent of medium, or across media, with human experience as an explicit outcome, and human engagement as an explicit goal.”1 in other words, applying a ux approach to thinking involves paying attention to a person’s behaviors, feelings, and attitudes about a particular product, system, or service. someone who does ux design, therefore, focuses on building the relationship between people and the products, systems, and services in which they interact. garrett provides a roadmap of sorts for us by identifying and defining the elements of a web user experience, some of which are the visual, interface, and interaction design, the information architecture, and user needs.2 in time, these come together to form a cohesive, holistic approach to impacting our users’ overarching experience across our library’s web presence. paying attention to these more contextual elements informs the development and management of a web site. let’s switch gears for a moment. prior to winning the election and becoming the lita vicepresident/president-elect, i reflected on my experiences as a new lita member and before i became really engaged within the association. i endeavored to remember how i felt when i had joined lita in 2005. was i welcomed and informed, or did i feel distant and uninformed? was the path clear to getting involved in interest groups and committees, or were there barriers that rachel vacek (revacek@uh.edu) is lita president 2014-15 and head of web services, university libraries, university of houston, houston, texas. mailto:revacek@uh.edu president’s message | vacek 2 prevented me from getting engaged? what was my attitude about the overall organization? how were my feelings about lita impacted? luckily, there were multiple times when i felt embraced by lita members, such as participating in bigwig’s social media showcase, teaching pre-conferences, hanging out at the happy hours, and attending the forums. i discovered ample networking opportunities and around every corner there always seemed to be a way to get involved. i attended as many lita programs at annual and midwinter conferences as i could, and in doing so, ran into the same crowds of people over and over again. plus, the sessions i attended always had excellent content and friendly, knowledgeable speakers. over time, many of these members became some of my friends and most trusted colleagues. unfortunately, i’m confident that not every lita member or prospective member has had similar, consistent, or as engaging experiences as i’ve had, or as many opportunities to travel to conferences and network in-person. we all have different expectations and goals that color our personal experiences in interacting with lita and its members. one of my goals as lita president is to enhance the member experience. i want to apply the user experience design concepts that i’m so familiar with to effect change and improve the overall experience for current members and those who are on the fence about joining. to be clear, when i say lita member, i am including board members, committee members and chairs, interest group members and chairs, representatives, and those just observing on the sidelines. we are all lita members and deserve to have a good experience no matter the level within the organization. so what does “member experience” really mean? don norman, author of the design of everyday things and the man attributed with actually coining the phrase user experience, explains that "user experience encompasses all aspects of the end-user's interaction with the company, its services, and its products.” 3 therefore, i would say that the lita member experience encompasses all aspects of a member’s interaction with the association, including its programming, educational opportunities, publications, events, and even other members. i believe that there are several components that define a good member experience. first, we have to ensure quality, coherence, and consistency in programming, publications, educational opportunities, communications and marketing, conferences, and networking opportunities. second, we need to pay attention to our members’ needs and wants as well as their motivations for joining. this means we have to engage with our members more on a personal level, and discover their interests and strengths, and help them get involved in lita in ways that benefit the association as well assist them in reaching their professional goals. third, we need to be welcoming and recognize that first impressions are crucial to gaining new members and retaining current ones. think about how you felt and what you thought when you received a product that really impressed you, or when you started an exciting new job, or even used a clean and usable web site. if your initial impression was positive, you were more likely to connect with the product, environment, or even a website. if prospective and relatively new lita information technologies and libraries | september 1014 3 members experience a good first impression, they are more likely to join or renew their membership. they feel like they are part of a community that cares about them and their future. that experience became meaningful. finally, the fourth component to a good member experience is that we need to stop looking at the tangible benefits that we provide to users as the only things that matter. sure, it’s great to get discounts on workshops and webinars or be able to vote in an election and get appointed to a committee, but we can’t continue to focus on these offerings alone. we need to assess the way we communicate through email, social media, and our web page and determine if it adds or detracts from the member experience. what is the first impression someone might have in looking at the content and design of lita’s web page? do the presenters for our educational programs feel valued? does ital contain innovative and useful information? is the process for joining lita, or volunteering to be on a committee, simple, complex, or unbearable? what kinds of interactions do members have with the lita board or the lita staff? these less tangible interactions are highly contextual and can add to or detract from our current and prospective members’ abilities to meet their own goals, measure satisfaction, or define success. as lita president, and with the assistance of the board of directors, there are several things we have done or intend to do to help lita embrace ux thinking: • we have implemented a chair and vice-chair model for committees so that there is a smoother transition and the vice-chair can learn the responsibilities of the chair role prior to being in that role. • we have established a new communications committee that will create a communication strategy focused on communicating the lita’s mission, vision, goals, and relevant and timely news to lita membership across various communication channels. • we are encouraging our committees to create more robust documentation. • we are creating richer documentation that supports the workings of the board. • we are creating documentation and training materials for lita representatives to compliment the materials we have for committee chairs. • we have disbanded committees that no longer serve a purpose at the lita level and whose concerns are now addressed in groups higher within ala. • the assessment and research committee is preparing to do a membership survey. the last one was done in 2007. • we are going to be holding a few virtual and in-person lita “kitchen table conversations” in the fall of 2014 to assist with strategic planning and to discuss how lita’s goals align with ala’s strategic goals of information policy, professional development, and advocacy. • the membership development committee is exploring how to more easily and frequently reach out, engage, appreciate, acknowledge, and highlight current and prospective members. they will work closely with the communications committee. president’s message | vacek 4 i believe that we’ve arrived at a time where it’s crucial that we employ ux thinking at a more pragmatic and systematic level and treat at it as our strategic partner when exploring how to improve lita and help the association evolve to meet the needs of today’s library and informational professionals. garrett summarizes my argument nicely. he says, “what makes people passionate, pure and simple, is great experiences. if they have great experience with your product [and] they have great experiences with your service, they’re going to be passionate about your brand, they’re going to be committed to it. that’s how you build that kind of commitment.”4 i personally am very passionate about and committed to lita, and i truly believe that our ux efforts will positively impact your experience as a lita member. references 1. http://uxdesign.com/events/article/state-of-ux-design-garrett/203, garrett said this quote in a presentation

faculty development cinthya ippoliti information technology and libraries | june 2019 5 cinthya ippoliti (cinthya.ippoliti@ucdenver.edu) is director, auraria library, colorado. the role of libraries within faculty development is not a new concept. librarians have offered workshops and consultations for faculty for everything from designing effective research assignments, to scholarly impact, and open educational resources. in recent months however, both acrl and educause have highlighted new expectations for faculty to develop skills in supporting students within a digital environment. as part of acrl’s “keeping up with…” series, katelyn handler and lauren hays1 discuss the rise of faculty learning communities that cover topics such as universal design, instructional design, and assessment. effective teaching has also recently become the focus of many institutions’ efforts in increasing student success and retention, and faculty play a central role in students’ academic experience. in addition, the educause horizon report echoes these sentiments, positing that “the role of full-time faculty and adjuncts alike includes being key stakeholders in the adoption and scaling of digital solutions; as such, faculty need to be included in the evaluation, planning, and implementation of any teaching and learning initiative.”2 finally, maha bali and autumn caines mention that “when offering workshops and evidence-based approaches, educational development centers make decisions on behalf of educators based on what has worked in the past for the majority.”3 they call for a new model that blends digital pedagogy, identity, networks, and scholarship where the experience is focused on “participants negotiating multiple online contexts through various online tools that span open and more private spaces to create a networked learning experience and an ongoing institutionally based online community.”4 so how does the library fit into this context? what we are talking about here goes far beyond merely providing access to tools and materials for faculty. it requires a deep tripartite partnership with educators and the centers for faculty development, as each partner brings something unique to the table that cannot be covered by one area alone. the interesting element here is a dichotomy where this type of engagement can span both in-person and virtual environments as faculty utilize both to teach and connect with colleagues as part of their own development. the lines between these two worlds suddenly blur and it is experience and connectivity that are at the center of the interactions rather than the tools themselves. while librarians may not be able to provide direct support in terms of instructional technologies, they can certainly inform efforts to integrate open and critical pedagogy and scholarship into faculty development programming and into the curriculum. libraries can take the lead on providing the theoretical foundation and application for these efforts while the specifics of tools and approaches can be covered by other entities. bali and caines also observe that bringing together disparate teaching philosophies and skill sets under this broader umbrella of digital support and pedagogy can help provide professional development opportunities for faculty, especially adjuncts, who may not have the ability to participate otherwise. this opportunity can act as a powerful catalyst to influence their teaching by implementing, and therefore modeling, a best-practices approach so that they are thinking about digial faculty develoment | ippoliti 6 https://doi.org/10.6017/ital.v38i2.11091 bringing students together in a similar fashion even if they are not teaching exclusively online, but especially if they are.5 open pedagogy can accomplish this in a variety of ways. bronwyn hegarty defines eight areas that constitute open pedagogy: (1) participatory technologies; (2) people, openness, and trust; (3) sharing ideas and resources; (4) connected community; 5) learner generated; (6) reflective practice; and (7) peer review.6 these elements are applicable to both faculty development practices, as well as pedagogical ones. just as faculty might interact with one another in this manner, so can they collaborate with their students utilizing these methods. by being able to change the course materials and think about the ways in which those activities shape their learning, students can view the act of repurposing information as a way to help them define and achieve their learning goals. this highlights the fact that an environment where this is possible must exist as a starting point and it also underlines the importance of the instructor’s role in fostering this environment. having a cohort of colleagues, for both instructors and students, can “facilitate student access to existing knowledge, and empower them to critique it, dismantle it, and create new knowledge.”7 this interaction emphasizes a twoway experience where both students and instructors can learn from one another. this is very much in keeping with the theme of digital content, as by the very nature of these types of activities, the tools and methods must lend themselves to being manipulated and repurposed, and this can only occur in a digital environment. finally, in a recent posting on the open oregon blog, silvia lin hanick and amy hofer discuss how open pedagogy can also influence how librarians interact with faculty and students. specifically, they state that “open education is simultaneously content and practice”8 and that by integrating these practices into the classroom, students are learning about issues such as intellectual property and the value of information, by acting “like practitioners” 9 where they take on “a disciplinary perspective and engage with a community of practice.”10 this is a potentially pivotal element to take into consideration when analyzing the landscape of library-related instruction, because it frees the librarian from feeling as if everything rests on that one-time instructional opportunity. the development of a community of practitioners which includes the students, faculty, and the librarian has the potential to provide learning opportunities along the way. including the librarian as part of this model makes sense not only as a way to signal the critical role the librarian plays in the classroom, but also as a way to stress that thinking about, and practicing library-related activities is (or should be) as much part of the course as any other exercise. information technology and libraries | june 2019 7 references 1 katelyn handler and lauren hays, “keeping up with…faculty development,” association of college

march 2012 5 as i was trying to settle on a possible topic for this, my second “editorial board thoughts” piece, i was struggling to find something that i’d like to talk about and that ital readers would (i hope) find interesting. i had my “eureka!” moment one day as i was coming out of a meeting, thinking about a conversation that had taken place around tools. now, by tools, i’m referring not to hardware, but to those programs and applications that we can and do use to make our work easier. the meeting was of our institutional repository team, and the tools discussion specifically focused on data cleanup and normalization, citation integration, and the like. i had just recently returned from a short conference where i had heard mentioned or seen demonstrated a few neat applications that i thought had potential. a colleague also had just returned from a different conference, excited by some of things that he’d learned about. and all of the team members had, in recent days, seen various e-mail messages about new tools and applications that might be useful in our environment. we mentioned and discussed briefly some of the tools that we planned to test. one of the tools had already been test driven by a couple of us, and looked promising; another seemed like it might solve several problems, and so was bumped up the testing priority list. during the course of the conversation, it became clear that each of us had a laundry list of tools that we wanted to explore at greater depth. and it also became clear that, as is so often the case, the challenge was finding the time to do so. as we were talking, my head was full of images of an assembly line, widgets sliding by so quickly that you could hardly keep up. i started thinking how you could stand there forever, overwhelmed by the variety and number of things flying by at what seemed like warp speed. alternatively, if you ever wanted to get anywhere, do anything, or be a part of it all, you just had to roll up your sleeves and grab something. the meeting drew to a close, and we all left with a sense that we needed to find a way of tackling the tools-testing process, of sharing what we learn and what we know, all in the hope of finding a set of tools that we, as a team, could become skilled with. i personally felt a little disappointed at not having managed to get around to all of the tools i’d earmarked for further investigation. but i also felt invigorated at the thought of being able to share the load of testing and researching. if we could coordinate ourselves, we might be able to test drive even more tools, increasing the sharon farnel (sharon.farnel@ualberta.ca) is metadata and cataloguing librarian, university of alberta, edmonton, alberta, canada. mailto:sharon.farnel@ualberta.ca editorial board thoughts | farnel 6 likelihood we’d stumble on the few that would be just right! we’d taken furtive steps towards this in the past, but nothing coordinated enough to make it really stick and be effective. i started wondering how other individuals and institutions manage not only to keep up with all of the new and potentially relevant tools that appear at an ever-increasing pace, but more so how they manage to determine which they will become expert at and use going forward. (although i was excited at what we were thinking of doing, i was quite sure that others were likely far ahead of us in this regard!) it made me realize that at some point i—and we—need to stop being bystanders to the assembly line, watching the endless parade of tools pass us by. we need to simply grab on to a tool and take it for a spin. if it works for what we need, we stick with it. if it doesn’t, we put it back on the line, and grab a different one. but at some point we have to take a chance and give something a shot. we’ve decided on a few methods we’ll try for taking full advantage of the tool-rich environment in which libraries exist today. our metadata team has set up a “test bench,” a workstation that we can all use and share for trying new tools. a colleague is going to organize monthly brown-bag talks at which team members can demonstrate tools that they’ve been working with and that they think have potential uses in our work. and we’re also thinking of starting an informal, and public, blog, where we can post, among other things, about new tools we’ve tried or are trying, what we’re finding works and how, and what doesn’t and why. we hope these and other initiatives will help us all stay abreast or even slightly ahead of new developments, be flexible in incorporating new tools into our workflows when it makes the most sense, and in building skills and expertise that benefit us and that can be shared with others. so, i ask you, our ital readers, how do you manage the assembly line of tools? how do you gather information on them, and when do you decide to take one off and give it a whirl? how do you decide when something is worth keeping, or when something isn’t quite the right fit and gets placed back on the line? why not let us know by posting on the italica blog? or, even better, why not write about your experience and submit it to ital? we’re always on the lookout for interesting and instructional stories on the tools of our trade! http://ital-ica.blogspot.com/ 156 information technology and libraries | december 2011 mark dehmlow editorial board thoughts: sharing responsibility in the digital age t his topic is very resonant for me because this past year we launched a new interface to our catalog, rich with all of the features that our users have been self-trained to expect from browsing the internet. we actually launched this project in public beta for two years, t–w–o years. i should also mention that the initial implementation team was diverse, drawing from technology, public services, collections, and technical services. yet, when we launched the project into production, it was only then that we heard concerns and complaints. those concerns revolved around two things—first, there was functionality in the classic catalog that wasn’t in the new one, and second, people were used to the old way of doing things and didn’t know how the supposedly more intuitive interface worked—a kind of opacholm syndrome, and more importantly for librarians, they wanted to know how to exploit the system powerfully. we also found during the first semester, there were few instructors teaching the new system because they were afraid they couldn’t speak authoritatively about it. people are creatures of habit and even though something might be easier to learn if it were your first exposure to it (macs vs. pcs anyone?), often times changing from a more complex, but well understood, process is difficult. i remember years ago at another institution i worked for, helping the organization move from a menu driven ils interface to a graphical user interface. it required staff to actually rethink the process they were performing because although the gui is able to make the process more efficient, it also hides many of the more mundane parts of it. with all of those concerns on the table all of a sudden, what did we do? we spent the summer after our production launch providing targeted training sessions and gathering in person feedback from our internal stakeholders. it probably amounted to more than thirty meetings over the course of three months. we synthesized feedback, identified the biggest pain points, and spent a couple of months developing solutions. providing a more organized training program and targeted feedback sessions as a replacement for our more generalized call for input bought us a lot of goodwill internally. it also gave us some direction on what areas to focus on and opened more dialog with the rest of the library. in the end, it is really important for all areas to be responsible for trying out new systems, even if those responsible are doing more outreach than simple general calls for participation. in some ways, those deploying new systems have the greater onus in this relationship in that they are driving many of the effort; this is especially critical for changes that have broad impact. taking a more organized and proactive approach to training and acclimating our organizations to change can go a long way to reducing conflict and stress. everyone is extremely busy, and the tendency for people is to ignore the things that aren’t directly in front of them. making efforts toward a more proactive strategy raises awareness and by meeting in person, you show people that their input is valuable enough to make time to listen and talk to them. taking this type of approach is important even in the cases where projects are managed by committees. liaisons don’t necessarily provide organizational saturation and oftentimes the vital information about a new system is filtered through their own sense of what is critical. a good start to determine how much communication is needed is to first gauge the potential impact—if a change affects more than a certain percentage of the library and its users, it probably means it will require a good deal more outreach so people don’t feel quite as off balance when the change is implemented. those deploying projects should add a couple of months onto the end of planning cycles to help provide training and gather feedback in a hands on way—e-mail announcements are more often ignored than not given the sheer amount of e-mail everyone gets these days. another possible strategy is to devise testing scripts for anyone trying the system to follow as opposed to just having them “try it out.” a script will give people some direction and hopefully get them into system functionality that they otherwise could miss by trying it without any specific goal. i am not so naive to think we will reach an allencompassing-kumbaya moment where communication is perfect and everyone agrees on what kinds of changes to implement in our organizations. i do think though, that teams and individuals who are implementing new systems can help alleviate anxieties if we build more time into our deployment processes to ease our organizations into change instead of hoping they learned how to swim before we all jump in. mark dehmlow (mdehmlow@nd.edu) is head, library web department, interim head, library information systems department, hesburgh libraries, university of notre dame, notre

tingle, and alexander watkins information technology and libraries | march 2017 29 abstract the increasing complexity of the information ecosystem means that research consultations are increasingly important to meeting library users' needs. yet librarians struggle to balance escalating demands on their time. how can we embrace this expanded role and maintain accessibility to users while balancing competing demands on our time? one tool that allows us to better navigate this balance is google appointment calendar, part of google apps for education. it makes it easier than ever for students to book a consultation with a librarian, while at the same time allowing the librarian to better control their schedule. our experience suggests that both students and librarians felt it was a useful, efficient system. introduction the growing complexity of the information ecosystem means that research consultations are increasingly important to meeting library users' needs. although reference interactions in academic libraries have declined overall, in-depth research consultations have not followed that trend.1 these research consultations represent an increasingly large proportion of academic librarians' reference interactions, and offer important opportunities to follow up on information literacy instruction, support student academic success, and relieve library anxiety. the library literature has demonstrated a need for and appreciation of these services.2 moreover, students value face to face consultations because they provide an opportunity to talk through complex problems and questions while providing affective benefits such as relationship building and reassurance.3 it is evident that students seek out and value these services. but even as these services become increasingly important, librarians struggle to balance escalating demands on their time. how can we embrace this expanded role and maintain accessibility to users while managing competing priorities? we found little guidance in the literature to identify the most efficient technological tools to offer these services to undergraduates, so we began to explore options. one tool that allows us to better navigate this shifting landscape is google appointment calendar, part of google apps for education. it makes it easier for students to book a consultation with a librarian,

calendar appointments (which is also no longer available), such as appointments booked without identifying information, and the extra step of logging in just for an appointment. because students are often already logged in due to using google apps for word processing, group work, and more, there is no extra step to log in for a simple appointment.5 our exploration of this tool suggests that it is helpful to librarians, but that it can also be of benefit to students, too. research has proposed that students may hesitate to ask questions due to library anxiety. would scheduling an appointment using a calendaring system be less intimidating than emailing a librarian directly, for example? we set out apply this technology in an environment of changing student preferences and expectations, explore how students received it, and establish effective practices for using it in an academic setting. since we are liaisons to science, social science, and humanities subject areas, we were able to work with a wide spread of undergraduate students in our exploration to see what might be most effective for us, and also for students from a variety of backgrounds. why google calendar we selected appointment booking via google calendar because of its ease of use and because the university of colorado boulder has google apps for education. this means that every student will have a google id and the option of using google calendar as part of their normal routine. in december 2012, google discontinued appointment calendars for general users, and limited claimable appointment slots to google apps for education. for institutions which who do not subscribe, it may be worth investigating third-party google calendar apps, some of which are free or freemium, such as calendly (https://calendly.com/), or springshare’s similar subscription service, libcal (https://www.springshare.com/libcal/). setting up google calendar one of the benefits of google calendar is its ease of use. starting to set up the calendar for appointment slots is as simple as creating a new google calendar event and selecting appointment slots as the type of event. next, you can give your appointment slots a name that correspond with the language your institution uses for research consultations, and schedule them for the desired length of time. it is possible to schedule blocks of appointments that google will automatically break into shorter appointments of predetermined amounts of time. the authors created appointments lasting 30 minutes, 60 minutes, or a mix of both, depending on the expectations of our disciplines. it is also possible to create several simultaneous appointment slots, if you would like to accommodate small groups. as well as indicating time, each appointment also has a space to indicate location, particularly useful for librarians who might work in several branches or combine office hours in academic buildings with in-library office consultations. once the events are named and saved, the calendar can be shared. information technology and libraries | march 2017 31 figure 1. create a new event, selecting ‘appointment slots’. appointment calendars are given a unique shareable url to direct users to available appointments; however, these urls are necessarily long and complicated, so we recommend using a link shortener. to obtain the very long url for an appointment calendar, click on ‘edit details’ in an appointment event. from there, it is possible to copy the link and use a link shortener to make a brief, understandable link. figure 2. obtain the shareable link when a student uses the link to make an appointment, both the librarian and the student receive an email with the student’s login name, email, appointment time, and other details. the slot immediately appears as taken on the calendar, so it is no longer available for other students, reducing confusion and double booking. receiving the student’s email allows the librarian to initiate the reference interview and establish expectations. facilitating research consultations using cloud services: experiences, preferences, and best practices | kuglitsch, tingle, and watkins | https://doi.org/10.6017/ital.v36i1.8923 32 figure 3. google calendar showing a variety of available appointments. student impressions we received positive feedback about the appointment calendars from students. students commented: ● “i like the ability to see all of the possible openings,” ● “i already bookmarked that bit.ly, so you’ll probably hear from me” (which we did, shortly thereafter). ● “i like to be able to ‘schedule’ a consultation, not request one. it seems more useful and immediate.” we kept track of how many students who made calendar appointments over two semesters kept them, and sent a short, informal survey to students who made appointments. no students who made a calendar appointment failed to attend their consultation. though our survey does not permit large-scale generalizations due to a very low response rate (4) and a small sample size (15), all of the students who responded and used the calendar found the experience of booking an appointment that way to be easy, convenient, and unintimidating. everyone who used the calendar indicated that they would prefer to use it again, and about half of the respondents who set up their appointments via email told us that they would prefer to book a consultation through information technology and libraries | march 2017 33 an appointment calendar in the future. our anecdotal evidence in succeeding semesters aligns with this perception. we found that using appointment calendars can have many benefits for students: ● they can reduce student anxiety from having to compose and send an email. ● booking appointments can take less of their time. they book immediately without back and forth emailing. this also means there’s no time to rethink the appointment and either never send the email or back out later. ● the appointment is placed on their calendar, meaning they automatically have a built-in reminder and don’t need to search through their email to find the date and time of their appointment. ● since the appointment calendars eliminate back and forth scheduling and reduce email fatigue, students may be more willing to use email to discuss their topic and/or question with the librarian. librarian impressions our experience has been equally positive. we found that using the calendars radically streamlines the typical back and forth email exchanges for setting appointments. we emailed each student to confirm the appointment, but this single email is still a significant reduction of claim on the librarian’s attention from a minimum of three emails to schedule an appointment (which often realistically becomes five or more when negotiating a time) to two. additionally, librarians can put appointment slots in between meetings and other times when they might only have a spare hour, which are often too tedious to list when emailing. using appointment calendars lets librarians efficiently use their time even when it is fragmented. as well as facilitating efficient use of small amounts of time, appointment calendars also allow librarians to gently create boundaries. rather than having to deny appointments requested for late nights or weekends, students are guided to viable times. while the use of google calendar is entirely voluntary at the university of colorado boulder we presented the tool at several reference librarian meetings with success and several other librarians have happily adopted the tool. one librarian who adopted the tool said: “sending a student a calendar that they can use to request a meeting eliminates the twelve messages back and forth on when to schedule a meeting. i also like that it puts the meeting on both our calendars, reducing the number of no-shows.” best practices our experiences and verbal feedback from students and librarians provided a foundation to develop best practices to minimize both librarian and student confusion. for students, confusion often centered around accessing the calendar, identifying which time slots were available, and identifying acceptable locations for appointments. the following best practices can help solve these difficulties. use a link shortener and a consistent naming convention so the links are similar for multiple librarians. using a link shortener makes it easy for students to jot down the calendar url, either to manually enter into a browser later or to quickly get to the link and bookmark it. this makes it easy for students to file the link and return to it at point of need. using a consistent naming facilitating research consultations using cloud services: experiences, preferences, and best practices | kuglitsch, tingle, and watkins | https://doi.org/10.6017/ital.v36i1.8923 34 convention makes it intuitive for students to transfer the appointment method over to other librarians’ cases for future research needs. if your link shortener is case-sensitive, create capitalized and lowercase versions of the link. many link shorteners are case-sensitive, unlike most urls, which can confuse students and lead to frustration when they try to access a link later. while this could be solved to some extent by using only lowercase letters for the shortened link, that solution can create a cumbersome and difficult to read short url. simply creating two forms of the link efficiently solves this. develop a naming convention so available appointment slots are obvious. we found that when naming time slots simply “consultation” students sometimes assumed that all appointments were booked when, in fact, every appointment was open. using a term like “available consultation” made it clear to students that the appointments were not already booked. google calendar automatically makes booked appointments unavailable, eliminating the opposite frustration. carefully consider the location in the bookable appointment form. google calendar allows librarians to enter or leave empty the location. if the field is left empty, users can specify a location, and students often filled in a location when none was indicated. if a librarian is not mobile, or is available in certain places only at certain times, it is key to identify a location. for example, in our study, one librarian held weekly office hours in two academic buildings; it was particularly important to identify which times the librarian was available in the library versus the academic buildings. on the other hand, it may also make sense not to designate a location. another of the authors, serving a population that used the main library, one branch library, and research area of the campus with no onsite library services, chose not to enter any location in order to accommodate the extremely dispersed population. users frequently indicated in which location they would be willing to meet, an option the librarian wanted to support in order to underscore the availability of services wherever users were located on campus. schedule two weeks of availability. we found that students could almost always find a time that worked for them with two weeks of available appointments. moreover, other than recurring office hours, it was difficult for librarians to predict their schedule further into the future than a few weeks. librarian concerns centered around keeping calendars synchronized, providing enough lead time for users to book appointments, and publicizing the service. we found several best practices that eased these concerns. designate a day each week to update hours and clear conflicts on the calendar. if google calendar is not the primary calendaring software for the library, it can be challenging to synchronize calendars. google calendar sends a calendar invitation to the librarian when an appointment is claimed, which they can accept on their primary calendaring system, but conflicts that arise on the primary calendaring system are not automatically sent to google calendar. by selecting a day and habitually updating the google calendar and quickly checking for conflicts that have arisen with unclaimed slots, librarians can avoid forgetting to add slots or remove those that conflict with other late-arising obligations. advertise the link on the library web site, give out the calendar link during class sessions and give it to professors to embed in course management systems. while appointment calendars still information technology and libraries | march 2017 35 benefit librarian workflows without advertising, students need easy access to the calendar. for maximum user uptake, it is important to put the calendar link anywhere a librarian’s contact information can be found. we found it helpful to promote the link in classes, and that it was particularly effective when professors agreed to place the link in the class web site. this positions library research assistance next to assignments when they are given out and drafts when they are returned--hopefully reminding students that the library is available for assistance at moments in which they are most likely to seek it. reflections and conclusions our experiences support the idea that online appointment calendars are appreciated by students, streamline work for librarians, and are easily adopted by both parties. more use of this technology, whether via google apps for education or another service, can be mutually beneficial to librarians and students. students using the calendar indicated that it was not more intimidating than emailing a librarian, and by removing the waiting period for a response, a calendar can prevent student distraction or students persuading themselves that they actually do not need help in the interim. by providing a calendar where students can quickly and simply book an appointment with a librarian for research assistance, librarians can support students seeking assistance, and thus ultimately bolster student success and increase the library’s relevance. references 1. naomi lederer and louise mort feldmann, “interactions: a study of office reference statistics,” evidence based library and information practice 7, no. 2

libraries | march 2022 https://doi.org/10.6017/ital.v41i1.13803 joseph letriz (jletriz@dbq.edu) is the electronic systems librarian, university of dubuque. © 2022. abstract rising costs of secondary education institutions, coupled with the inflated cost of textbooks, have forced students to make decisions on whether they can afford the primary materials for their classes. publishers working to supply digital access codes, which limit the ability of students to copy, print, or share the materials, or resell the textbook after the course is over, have further pushed students into forgoing purchasing materials. in recent years, institutions have moved to support oer (open education resources) initiatives to provide students a cost-free primary text or supplement to their materials. this allows students unfettered access to quality resources that help drive engagement in courses, from homework to discussions. while larger institutions or in-state partnerships with resource sharing consortiums, such as the mnpals cooperation with the state of minnesota, provide access to platforms like pressbooks, smaller institutions and private colleges don’t always have the ability to negotiate these types of relationships. in this case study, i will cover the foundations necessary to start a low-cost, self-hosted solution to support faculty creation of oer material and the available resources that the university of dubuque utilized in their development process. this overview will briefly cover the skills and knowledge needed to support the growth of this initiative with minimal complexity and as little jargon as possible. introduction at the university of dubuque, the library installed, configured, and deployed an instance of pressbooks to support faculty development of open education resources (oer). the university of dubuque is a small, private university with a total full-time enrollment (fte) of about 2,000. two library personnel lead the deployment of the resource. as many universities find themselves grappling with an increase in textbook costs and other barriers to students’ access to quality information, libraries have emerged as a natural partner within institutions to identify, curate, and provide access to quality oer. okamoto points towards a variety of ways that libraries have managed this, including the community college consortium for open education resources (cccoer), which includes “150 member colleges … promot[ing] oer adoption to enhance teaching and learning.”1 braddlee and vanscoy state that librarians hold an important role in “supporting faculty and students in expanding the range of oer” through a number of methods, referencing prior research that okamoto performed.2 from a number of interviews from similarly sized liberal arts colleges, schleicher et al. state that librarians leading the initiatives for oer “may need technical skills … to assist faculty in developing oer projects.” 3 the benefits for students in terms of cost alone show that oer supported projects, such as the launch of pressbooks at the university of dubuque, has longstanding benefits for faculty, students, and the library.4 mailto:jletriz@dbq.edu information technology and libraries march 2022 local hosting of faculty-created open education resources | letriz 2 pressbooks is an open-source book content management system, making the software free for anyone to utilize, customize, and remix. with an open-source software as the basis for this project, the university of dubuque could view and change any of the underlying codebase to fit their exact needs to provide a platform for faculty to publish and develop oer content for their classes and students. the overlaying interface and configuration of pressbooks is built upon a fresh installation of the wordpress blog hosting system utilizing the multisite feature. these two systems are free to install, configure, and deploy on a locally hosted or cloud-based network. larger consortiums, which can consist of state level organizations, universities, and partnerships with businesses, may have the flexibility in spending to fund a hosted solution from the company itself. the cost of paying for a hosted solution can vary depending on the needs of the community served. a pressbooks edu single network plan, hosted by pressbooks, can cost $7,000 a year for the silver plan or $14,000 a year for the gold plan.5 at the university of dubuque, we opted for the low-cost solution of locally hosting our installation, which involved configuring the software locally and providing our own support for the faculty and students utilizing it. in this case study, i will detail how we successfully deployed the instance of pressbooks for the university of dubuque. this case study will cover the documentation used, the systems and services utilized to support the network, and the timeline from beginning the project to its successful launch. documentation to start the installation process, there needs to be a web server to host the pressbooks instance. at the university of dubuque, we used an already configured amazon web services (aws) account to set up the server that pressbooks would run on. aws offers a variety of tiers for its web server hosting, from the smallest available configuration that can be used for free to larger, more powerful instances for public access. at the university of dubuque, we opted for the aws t3a.large instance type, which gave us access to a faster server load for processing the installation and running the instance operations, as well as better network bandwidth.6 once we had the instance type selected, aws allowed for configuration of a variety of operating system (os) installations that come preconfigured or an à la carte option. we chose the same os platform that we utilize for our digital repository, a c-panel, centos 7 instance, as we already owned an educational software license for it. c-panel offers a reduced cost, education license available for any institutions with a .edu domain. the application to receive an educational license for the c-panel account takes little time to fill out and the only cost associated with the initial application is a $30 processing fee.7 once c-panel activated the education license on our primary platform, the license was utilized on the other instances without having to worry about multisite or platform license fees. aws launches the instance in the ec2 services page listed under the account, which details the instance’s setup, volumes attached to the instance that the software gets installed on (with additional volumes available to add onto the instance if necessary), and the ability to create snapshots of the instance for backups and restoration of the installation configuration. aws categorizes volumes as the primary storage devices for the installation, akin to a virtual hard drive, while the snapshots function as a copy of that storage device. during the configuration process, aws provides additional information about all of the options available in their ec2 service. as these are not directly relevant here, i will not go into detail about them. at the university of dubuque, we had preconfigured security groups and snapshot schedules set up that we applied to the pressbooks instance before we installed the underlying software. information technology and libraries march 2022 local hosting of faculty-created open education resources | letriz 3 the primary documentation used for the platform setup before installing the platform came from the pressbooks documentation site.8 the documentation begins by directing users to wordpress and their famous 5-minute install. wordpress documents are available on their website (https://wordpress.com/support/); installation directions include prompts that guide users through the entire setup and configuration process. once the wordpress installation process is complete, pressbooks can be set up on top of the wordpress site by following the installation directions from the pressbooks documentation. the beginning portion of configuring the wordpress site for pressbooks involves editing the configuration file for wordpress to allow for multisite setups on the single instance of wordpress. once the pressbooks site is installed, pressbooks will require additional plugins through wordpress in order for pressbooks to function correctly. again, the installation documentation for pressbooks walks through each of the necessary plugins, providing directions on how to configure the files for the installation to work correctly, how to start the configuration of users and appearance, and how to begin the creation of digital materials on the site. access to pressbooks can be set up through the installation itself, using plugins to link the installation to microsoft office accounts, google accounts, or any others that might be used. once this final step is completed (which will vary institution by institution depending on what service the institution utilizes for their primary authentication method ), the pressbooks site is ready to be utilized. there are two kinds of regular maintenance needed to keep the installation up to date. the first relates to the pressbooks and wordpress installations and updates, changes to configurations, additions, or deletions for the instance. most of these software updates, configuration changes, and plugin updates are handled through the pressbooks interface under the network manager administrator menu. since pressbooks is a layered software that’s built on the wordpress platform, all of the network configuration options use the same wordpress tools and user interface. the second kind of maintenance is done through a terminal command-line interface (cli) connection to the aws instance. this includes server maintenance tasks, which can be preconfigured through a script run on the server or handled by an administrator with sufficient knowledge of the system. the cli can also locate the error logs to pinpoint any errors that may have happened during setup and configuration. this maintenance can run on a monthly schedule, usually to ensure that web hosting software or internet access services are running correctly on the aws instance in addition to any server updates for the os and installed platform. at a smaller institution, the work on pressbooks can be handled by a librarian or professional staff member, as wordpress makes the procedure as simple as possible for anyone. the command-line interface work, if an os is installed without a user interface, can be handled by either a librarian familiar with terminal commands or a member of the institution’s help desk or information technology support personnel. any additional dependencies outside of what comes with wordpress are easily handled through the same network manager administrator menu. most installs include a number of default configuration options, such as uploading documents, printing from a pdf, or view functionalities. at the university of dubuque, any additional dependencies were all installed using wordpress and configured on pressbooks without any need to access the server directly. for a smaller institution, this makes the process of approaching a self -hosted solution sustainable over time, as it does not require specialized knowledge of servers to handle pressbooks once it is installed. https://wordpress.com/support/ information technology and libraries march 2022 local hosting of faculty-created open education resources | letriz 4 working with faculty to add materials and address concerns when we launched pressbooks at the university of dubuque (http://pressbooks.dbq.edu) and wanted to showcase how using the platform would be advantageous, we worked with a geology professor who had already created his own textbook for his entry level geology course. the pdf he created was over 170 pages long and included all of the terminology, concepts, and example questions the students would see on the quizzes.9 we worked with the professor to get the original word document of his textbook, complete with his own layout structure, font, and headings, correctly formatted to import into pressbooks. the system manages the import process by utilizing very basic formatting of the document, identifying chapters based on the heading types.10 essentially, the library staff worked with the professor to sanitize the document of all unnecessary formatting, laid out the primary chapter headings in the document using the word heading formats that are supported, and then processed the document through the pressbooks tools for importing. with the primary example uploaded and ready to showcase to the faculty members, our library director began fielding the requests of other faculty members at the university of dubuque.11 the current process for working with faculty involves sending any interested faculty the list of required reading that pressbooks has hosted on their website. this includes materials related to creating the content directly in pressbooks, importing the content from a word document if authors already have something they want to use, and setting up an account as an author on pressbooks. in addition to the geology professor mentioned above, two additional faculty members in vastly different departments, computer information science and philosophy, used our pressbooks instance to curate their materials for their students. as the instance is built on a wordpress multisite installation, library staff are able to install and configure a variety of additional material for faculty—enabling practice quizzes, the list of glossary terms to study, and other material—either through the native pressbooks interface or with the assistance of opensource plugins such as h5p, a plugin that allows community-created videos, presentations, quizzes, and interactive content to be created, shared, and reused. all of these additional configuration options, including adding the additional tools for faculty, are handled through the network manager administrator menu. faculty with questions or needs for assistance can reach out to library personnel directly through email or by setting up a teams or zoom call to walk through the problem they might have or express a need that they can assist with. looking back/reflections throughout the process, the university of dubuque’s work came to fruition through the efforts of one librarian focused on the application and server side management and a library worker who was familiar with mysql query language and data management. this partnership proved invaluable in working with the nuances of configuring the sql database to the necessary specifications. for any institution looking to have an uncustomized database, the wordpress installation configuration options work without any additional knowledge or customization necessary. the library’s access to the aws instance from the campus needed involvement by the campus information technology department’s help desk to approve the ip address on file for the dns configuration. in simpler terms, once the library set up the aws instance with an elastic ip address (the term amazon uses on aws to refer to their ranges of ip addresses) and configured the domain information on pressbooks through the installation, the library provided that information to the help desk and they updated the necessary documents and certificates. the last http://pressbooks.dbq.edu/ information technology and libraries march 2022 local hosting of faculty-created open education resources | letriz 5 piece of the process, inviting users to utilize installation, required the most patience and is an ongoing process. in setting up the accounts locally, for more restricted access, pressbooks provides only temporary account status to any created user accounts. this means if a faculty member has an account created for them by the institution in july but doesn’t attempt to sign in to the account until september, pressbooks will not hold onto that information in the sql database. after a default period of three days, which is customizable through the wordpress configuration options, the username is not retained by the system and the new account creation process has to begin again. there are options to link the installation to a single sign-on system, such as microsoft’s adfs or a program such as shibboleth or google apps. directions for setting up this configuration option are also available as part of pressbooks documentation on their website. at the university of dubuque, having a small fte allows for more time to work closely with a faculty member throughout the oer creation process, as the faculty are more flexible with their time. the current process of creating accounts as needed, on an individual basis, wor ks well when handling limited requests. larger institutions that would utilize this method of configuration might find it easier to streamline the request through a single sign-on system, an authentication method that is automated through an administrator or pressbooks or another program. additional needs after the rollout of the pressbooks site to the campus community, we encountered additional needs for our instance that weren’t configured as part of the base installation of the site. for faculty members registered for an account on the site, pressbooks would allow their account to have basic user access to the features necessary to start creating their oer. however, this did not allow for the usage of a majority of the features that pressbooks offers. part of this disconnect stemmed from the way the accounts were created on our multisite instance. accounts created need to be manually added and confirmed as an existing account on the pressbooks site as an author in order to allow access to the full suite of options available for the oer creation. the other hang-up in access for faculty came from the way pressbooks handles email for new registration, password change information, or any type of communication. prior to june 2020, developers were able to simply connect a wordpress site, or other sites, to gmail using a simple authentication of their account using their username and password. in june 2020, google required users who want to utilize gmail to send emails from a new site, or in this case a locally created instance of a wordpress multisite for pressbooks, to authenticate their account information by authorizing the site through a google developer api, paying for access to the plugin that would allow for configuration of gmail, outlook, or other email providers, or rely on the site maintainers to configure their own email services through the server itself.12 if it is built into the budget of the university to purchase and subscribe to a service provided by a plugin owner, that option works without additional server configuration. our institution, however, was limited in its payment options and was unable to utilize standard forms of payment required by the plugin providers. as such, we are manually reviewing the registration requests for the site and creating accounts on pressbooks on an as-needed basis. information technology and libraries march 2022 local hosting of faculty-created open education resources | letriz 6 concluding thoughts the university of dubuque’s initial introduction to pressbooks came from attending the library technical conference 2019, held at macalester college in minnesota. while there, representatives from the mnpals consortium walked through the work done between the university of minnesota and the state library system to integrate their instance of pressbooks throughout public library systems and university systems.13 the work done at our institution is at a significantly smaller scale, only being utilized by faculty members at the university and members of the university community, including adjunct professors and professional staff. while work on a consortium level can proceed quickly, as there are multiple parties involved in the creation of the resource, we at the university of dubuque had a small number of people immediately working on the project. the discussion between the two personnel in the library handling the system work and the director of the library took the longest amount of time, followed by a couple of months between contact with pressbooks about pricing, hosting through them, and conversations at the state level attempting to gauge interest from additional parties to partner with. initial conversations at local state conferences, with the larger public institution librarians participating in discussions, didn’t evolve into an actionable plan. from there, the planning for the setup of the aws instance to install wordpress and pressbooks took a month to set up. another two weeks were spent working with the mysql database to customize it to the university’s needs and upload the instructor book used as the pilot upload. from start to finish, seven months passed to the launch and rollout of the product. since the launch of the platform, work has started on identifying faculty who would benefit from using pressbooks, with surveys across the institution to glean insight into what faculty are currently doing, how they and their students can benefit from this, and all the steps involved. with the work done at the university of dubuque, operating as a private, smaller university allowed for more flexibility in our adoption of technology, a more focused approach to introducing new systems to the university at large, and a less bureaucratic approach to seeking approval. in the library, we recognized that we were in a unique position to begin this development and implementation rapidly for the university and took advantage of that. endnotes 1 karen okamoto, “making higher education more affordable, one course reading at a time: academic libraries as key advocates for open access textbooks

faculty to add materials and address concerns looking back/reflections additional needs concluding thoughts endnotes data center consolidation at the university at albany rebecca l. mugridge and michael sweeney information technology and libraries | december 2015 18 abstract this paper describes the experience of the university at albany (ualbany) libraries’ migration to a centralized university data center. following an introduction to the environment at ualbany, the authors discuss the advantages of data center consolidation. lessons learned from the project include the need to participate in the planning process, review migration schedules carefully, clarify costs of centralization, agree on a service level agreement, communicate plans to customers, and leverage economies of scale. introduction data centers are facilities that house servers and related equipment and systems. they are distinct from data repositories, which collect various forms of research data, although some data repositories are occasionally called data centers. many colleges and universities have data centers or server rooms distributed across one or more campuses, as does the university at albany (ualbany). this paper reports on the experiences of the libraries at ualbany as the libraries’ application and storage servers were consolidated into a new, state-of-the-art, university data center in a new building on campus. the authors discuss the advantages of consolidation, the planning process for the actual move, and lessons learned from the migration. background the university at albany is one of four university centers that are part of the state university of new york (suny) system. founded in 1844, ualbany has approximately 13,000 undergraduates, 4,500 graduate students, and more than 1,000 faculty members. it offers 118 undergraduate majors and minors, and 138 master’s, doctoral, and certificate programs. ualbany resides on three campuses: uptown (the main campus), downtown, and east.1 the uptown campus was built in the 1960s on grounds formerly owned by the albany country club. the campus was designed by noted architect edward durell stone in 1962–63 and was built in 1963–64. the campus buildings include four residential quadrangles surrounding a central “academic podium” consisting of thirteen three-story buildings connected on the surface by an overhanging canopy and below ground by a maze of tunnels and offices. many of the university’s classrooms, lecture halls, academic and operational offices, and infrastructure are housed within the podium on the basement or subbasement levels. this includes the university’s original data center, which is located in a basement room in the center of the podium. rebecca l. mugridge (rmugridge@albany.edu) is interim dean and director and associate director for technical services and library systems, and michael sweeney (msweeney2@albany.edu) is head, library systems department, university libraries, university at albany, albany, new york. mailto:rmugridge@albany.edu mailto:msweeney2@albany.edu data center consolidation at the university of albany | mugridge and sweeney | doi: 10.6017/ital.v34i4.8650 19 while visually striking and unique, the architectural design of the podium presented many challenges since its construction, one of which is regular flooding of the basement and subbasement levels. the original data center was flooded many times, to the extent that any heavy rainstorm had the potential to disrupt functionality and connectivity. when the university was first built in the 1960s it was not known to what extent computing would become part of the university’s infrastructure, and the room that the data center was housed in was not built to today’s standards for environmental control, such as the need for cooling. at the same time, server rooms sprouted all over the university, with many of the colleges and other units purchasing servers and maintaining server rooms in less than ideal conditions. these included server rooms in the college of arts and sciences, the school of business, the athletics department, the university libraries, and many other units. university libraries’ server room the university libraries maintained its own server room with two racks full of equipment that supported all of the libraries’ computing needs. these servers supported our website, mssql and mysql databases, ezproxy, illiad (interlibrary loan service), ares (electronic reserve service), and our search engine appliance (google mini). they also included our domain controller, intranet, and several servers used for backup. two servers and a storage area network housed our virtual environment, containing an additional nine virtual servers. these included servers to support library blogs, wikis, file storage, development and test servers, and additional backup servers. the only library servers not housed in the libraries’ server room were the integrated library system (ils) servers that were maintained primarily by the university’s information technology services (its) staff, our backup domain controllers, and a server holding backups of our virtual servers. the ils production server was housed in ualbany’s data center and the ils test/backup server was housed in the alternate data center in another building on campus. also, two of the libraries’ backup servers for other applications were housed in the university data center. the libraries’ server room consisted of a 340 square foot room on the third floor of the main campus library that was networked to support servers housed in two racks protected by a fire suppression system. there were two ceiling-mounted air conditioning units that cooled the room sufficiently for optimum performance. the libraries’ windows system administrator’s office was nearby and had a connecting door to the server room, giving him ready access to the servers when needed. data center consolidation data center consolidation is defined as “an organization's strategy to reduce it assets by using more efficient technologies. some of the consolidation technologies used in data centers today include server virtualization, storage virtualization, replacing mainframes with smaller blade server systems, cloud computing, better capacity planning and using tools for process automation.”2 in addition to the investigation and use of these technologies, the planning for a information technology and libraries | december 2015 20 new data center often involves the construction of a new building or the renovation of a current building. there were several drivers behind the ualbany’s decisions to build a new data center. in addition to the concerns mentioned above about the potential flooding risk of the current data center, the ability to manage optimum temperature was also a factor. the current data center was built to house 1960s-era equipment and was not able to keep up with the cooling requirements of the more extensive computing equipment in use in the twenty-first century. the current data center also occupied what is considered prime real estate at the university, at the center of campus and near the lecture center, which experiences high foot traffic during the academic year. the new data center was constructed near the edge of campus, with little foot or auto traffic, allowing the space previously occupied by equipment to be repurposed in a way that better meets the university’s needs. like many other universities, ualbany is increasingly making use of cloud computing capabilities. for example, the email and calendaring system are cloud-based. nevertheless, this movement is being made in a deliberate and thoughtful way, leaving many of our administrative computing needs reliant on the use of physical servers. ualbany and the libraries have decreased the number of physical servers necessary by relying on a virtualized environment, and part of the project to move to the new data center included a conversion from physical to virtual servers. the libraries’ ils production and test servers remain physical, as do several of the other libraries’ application servers. many of the libraries’ backup servers are now virtual. while there was no official mandate to consolidate all of the distributed server rooms across campus into the new data center, everyone involved understood that this was a direction the university administration supported. the libraries’ dean and director also supported this effort on behalf of the libraries and charged libraries’ staff to collaborate with its to make this happen. some of the drivers behind this decision include the promise of a better environment, improved security, backup generators for computing equipment, the use of its’s virtual environment, the automation of server management, a faster network, the ability to repurpose the libraries’ server room, and more. these drivers are described in more detail later in this paper. construction planning for ualbany’s new data center began in the mid-2000s and included the identification of funding and the architectural design of the new building, later to be named the information technology building (itb). the actual construction began in 2013, with an estimated completion date of february 2014 and occupancy in april 2014. unexpected challenges during construction delayed the timeline somewhat, and the construction was not completed until may 2014. the certificate of occupancy was granted in fall 2014. the data center is certified as tier iii by uptime institute,3 and the building is designated leed gold. data center consolidation at the university of albany | mugridge and sweeney | doi: 10.6017/ital.v34i4.8650 21 alternate data center simultaneously with the construction of the new data center, the university entered into an agreement with another suny institution to house our alternate data center. this center was originally housed in another building on the ualbany campus, less than a mile from both the main data center and itb, in a building leased by ualbany. this situation left some environmental issues out of our control, not an ideal situation. for example, an air conditioner failure in fall 2013 caused our backup and test ils server to be down for six days, affecting our ability to use that server for other purposes and holding up several projects. in addition, data center best practice calls for an alternate data center to be housed at a distance from the main data center. in february of 2014, the servers in the alternate data center were moved to their new location. this included the libraries’ backup ils server as well as two backup servers formerly housed in the main data center. advantages to the libraries moving to the university data center there were many advantages to the libraries moving to a centralized data center. many of these advantages also applied to the other units considering a move to the new data center, but for the purposes of this paper, we are addressing them in the context of the libraries’ experience. repurpose space the libraries’ server room occupied a large office that could be repurposed to house multiple staff offices or student spaces. the libraries have many group study rooms available for student use; however, they are in great demand, and the possibility of gaining more space for student use was seen as an advantage to making the move to a new data center. climate control the new data center is built on a raised floor that allows better air circulation. hundreds of servers and other pieces of equipment create a lot of excess heat, and raised floor construction allows for better circulation of air. new racks have chimneys that exhaust heat from high-density computing environments. air conditioners supply a constant stream of air that will maintain the optimum temperature for computing equipment. censors continually monitor humidity and keep it at an optimal level. this was an improvement over the libraries’ current server room, which had sufficient air conditioning for our relatively small number of physical servers but did not have backup generators to keep equipment running during a power outage. backup generators the new data center was built with two backup generators. if the building suddenly loses power, the backup generators will immediately start and provide a seamless source of energy. a secondary benefit to the university is that the backup generators can also provide a source of energy to other buildings on that side of campus; this area did not previously have a backup source of energy. again, the libraries’ server room did not have a redundant electrical supply. in information technology and libraries | december 2015 22 the event of a power outage, battery units would allow the servers to shut down properly if the outage lasted more than forty-five minutes. security with server rooms scattered all over the university, security issues were a concern. now that the servers are housed in one location, the university can provide a highly secure environment in a more cost effective way. the new data center has card-swipe access to the building and biometric access to the data center itself. there are also cameras installed in the building as a further security measure. virtual environment although the libraries have made strides toward moving into a virtualized environment in the past few years, we had many constraints on our ability to keep up with developments. the libraries’ virtual environment was two versions behind ualbany’s virtual environment, and the storage needs of the libraries’ virtual environment were at capacity. part of the incentive to moving into the new data center was the ability to downsize some of our physical equipment and migrate some of our physical servers to virtual equivalents. automation of server management one of the benefits of consolidating servers into one environment is that they are in a secure location, but it is still possible to manage them from a distance. the virtual environment has a web-based console that allows system administrators to connect and manage them, and the physical servers can be managed over the network as well. even though the servers are centralized, our system administrator can work from an office in the library, or from home if needed. faster network part of the project to construct a new data center included the installation of an additional fiber network across campus. the new fiber network connects all buildings on campus with each other and the new data center. all of the network equipment was upgraded, providing faster connections and response time. the additional fiber network is fault tolerant: if the primary network fails, the second fiber network can immediately take its place with no loss of service. staging and work room the new data center was designed to include a staging and work room. this can be used by any of the system administrators who are responsible for equipment housed in the data center, and it allows them to work on equipment in a room adjacent to the locked and secure data center. data center consolidation at the university of albany | mugridge and sweeney | doi: 10.6017/ital.v34i4.8650 23 equipment inventory part of the planning for the migration involved creating a detailed inventory of equipment. the libraries already had a server inventory, but the information collected for the migration went far beyond just a list of the servers. this helped us identify who was responsible for physical and virtual servers and who was responsible for the services and applications that ran on those servers. creating the equipment inventory also allowed us to consolidate and decommission equipment that was no longer needed, and additionally helped us determine a prioritization and time line for the move. applications inventory in addition to creating an equipment inventory, the libraries created an applications inventory that included information about the dependencies that applications had on each other. for example, the libraries’ electronic resources reserve application (ares) had been integrated into the university’s course management system, blackboard. that meant that when blackboard was inaccessible, ares was as well. all of these dependencies had to be taken into account when planning the schedule for the move. disadvantages to the libraries moving to the university data center the libraries have noted few disadvantages to moving to the new data center. what might seem like disadvantages are in reality just a change in the way we do our work. for example, we have been asked to inform someone in its before we go to the new data center to work on a server. this is a simple step, and has not hindered our work at any time. another change is the need to use a tool created by its to configure our virtual servers, and we found that the tool has been configured to give us fewer administrative options than what its staff have. this has reinforced our understanding that we need to be present and proactive in representing the libraries’ interests in managing all of our computing equipment and software. migration days the majority of ualbany’s servers were moved from the main data center to the new one in itb on august 9, 2014. however, we were unwilling to move all of the libraries’ servers on that day, which fell in the middle of the summer session. a compromise was reached between the libraries and its that allowed many of the libraries’ less mission-critical servers to be moved on the same day as the university’s servers. these servers were primarily ones that were used for development and backup purposes, one exception being the server that supported the libraries’ electronic reserves service. this server was dependent on the university-supported blackboard server, which was being moved on august 9, so the libraries’ agreed to move this server that day so there would not be two downtimes for the electronic reserve system. the libraries’ most critical servers were moved to itb on august 18, 2014. this was the first day of intersession and would affect students and faculty the least. there were many people involved information technology and libraries | december 2015 24 in the move, including the library systems staff, the migration consulting firm staff, the professional moving company that was hired to carry out the move, and its staff who were responsible for the network and other support. move activities included shutting down and backing up applications, powering off the servers, and packing the equipment. at itb the equipment was unpacked, placed in its assigned rack location, plugged in, and powered on. then each server had to be started, and applications tested. all of this activity began at 3:00 a.m. and continued until early afternoon. the day concluded with a conference call between all parties involved to confirm that everything was up and running as expected. lessons learned participate in the process the libraries were invited to participate in the planning for a new data center early in the process. its, ul, and other units with significant server collections met and discussed their computing needs and respective computing infrastructures. once the construction of itb began, the planning ramped up and monthly meetings of stakeholders became weekly meetings. agendas for these meetings included round robin reports about • construction project oversight; • migration consulting; • partnerships (with other units on campus, including the libraries); • status of our alternate data center (housed 10 miles away at another suny institution); • campus fiber network; • internal wiring and network design; • administrative computing planning and move; • research computing planning and move; • systems management (storage and virtual environment) planning and move; • data center advisory structure; and • campus notification and public relations. these meetings gave us an opportunity to learn about and understand all aspects of the data center migration project. participants reviewed project timelines and other documents that were housed on a shared wiki space. after the data center migration consultants were hired, they began to use the microsoft onedrive collaboration space to share and distribute documents. meeting regularly with all project participants allowed us to ask questions to clarify priorities and timelines and to advocate for the libraries’ needs. review schedules carefully as with many construction projects, unexpected delays in the construction of the data center delayed all of our plans. originally the building was to be completed in february; this was later data center consolidation at the university of albany | mugridge and sweeney | doi: 10.6017/ital.v34i4.8650 25 changed to april and then may. after the construction was complete, the building had to be commissioned, which means that every system within the building had to be tested independently by outside inspectors. coordination of this work is very time consuming, and the completion of the commissioning delayed occupancy by another few months. the university was finally given permission to move equipment into the data center in july. in the meantime, our consultants were working feverishly to develop timelines for the move, identify, and secure a contract with a professional it moving company, and create “playbooks” for each move. the playbook is a document that includes • names and contact information of everyone involved with the move; • sequence of events: an hour-by-hour description of all activities; • server overview: including the name, make, model, rack location and elevation, and contact person for each server; and • schematics of both old and new server locations including details about each server as well as rack locations and elevations. library staff became concerned when the original date scheduled to move most of the university’s application servers, including the libraries’ ils server, was in the middle of the summer session. although the projected downtime was only to be twelve hours (and probably fewer), library staff were not willing to have twelve hours’ downtime during a short four-week summer session. there were concerns that downtime, not only to the online catalog, but also to all of the libraries’ databases, the website, online reference service, electronic reserves, and other resources would present a severe hardship to faculty and students. we also recognized the risk, however small, of something going wrong during the move that would cause a lengthier downtime. at the same time the university was concerned about pushing the move too close to the start of the fall semester, as well as the increased cost of scheduling a second move date. during these negotiations it became apparent that the libraries’ needs are different from administrative computing needs. whereas the middle of a semester is a poor time for libraries’ servers to experience downtime, it can be a better time for administrative computing, which is often busier during intersession when grading reports are being run and personnel databases are being updated. ultimately, the libraries advocated for and secured an agreement for a second move date, scheduled for the first work day after the end of the summer session. similarly, its was encouraging all of its partners across the campus to move as much computing as possible into their virtual environment. this is a worthwhile goal, but again the libraries had to negotiate to make this change according to the schedule best for the libraries and its users. the its virtual environment was a more current release of the virtual machine (vm) software than the libraries were using, so the libraries were faced with not only a migration, but also an upgrade. ultimately, we postponed the vm migration until after the physical migration, and we have information technology and libraries | december 2015 26 benefited from waiting. other partners have had to work through a number of kinks in the process, and the libraries’ vm migration has benefitted from the other partners’ experience. clarify costs of centralization when ualbany began to consider and plan for a centralized data center, one of the concerns raised by the various data center managers from units other than its was the cost of centralizing their servers in another location. centralized data centers have many costs: heating, cooling, security, staffing, cleaning, backup energy sources, networking costs, and more. the question on everyone’s mind was who was going to pay for these costs. would each unit have to pay toward the maintenance of the data center? some objected to the idea of having to pay to be a tenant in a centralized data center, when they already had their own data center or server room at what seemed like no cost. the only cost they experienced was an opportunity cost of what else they could use the server room for. in the libraries’ case, the server room could be used for group study, office space, or other purposes, but it did not cost the libraries money to use it as a server room because utilities are covered centrally by the university. on the other hand, by migrating some of our computing to the its virtual environment, we may save money in the long run because we will not have to replace hardware and pay warranty fees. after much negotiation the university settled on a five-year commitment to no charges for the partnering units on campus, including the libraries. this agreement was documented in a partnership agreement drafted by a group of representatives from all of the key units involved. contribute to the development of a service level agreement library staff contributed to the development of a service level agreement (sla) for our participation in a centralized data center. having an sla in place ensures that all parties to the agreement understand their rights and responsibilities. we began by searching other universities’ websites for samples of slas, which we shared with its staff who were assigned to this project. the establishment of a centralized data center includes several major elements: data center as a service (dcaas), infrastructure as a service (iaas), as well as the network that connects it all. the sla that was developed, still in draft form, has elements that address the following: • the length of the agreement • network uptime • infrastructure as a service o server/storage environment and technical support o access to iaas o file backup and retention o maintenance of partner systems o its scheduled maintenance o data ownership, security, responsibility, and integrity data center consolidation at the university of albany | mugridge and sweeney | doi: 10.6017/ital.v34i4.8650 27 o business continuity, tiering, and disaster recovery o availability and response time of its staff • data center as a service o environment and support o building access and security o physical rack space o deliveries o scheduled maintenance o communications • glossary we recommend that institutions considering data center consolidation projects complete their sla and other agreements before moving servers into a shared environment. in our case, however, we were unable to finalize the sla prior to the actual move. this was not because of any particular demands that the libraries were making, but was primarily because of the rapid approach of the deadline for moving into the new data center. it had to be completed before the beginning of fall semester, and preferably with a few weeks to spare in case anything went wrong. while the planning for the data center construction and migration seemed to stretch over a long period of time, the final few months turned into a frenzy of activity that ranged from last-minute construction details to nailing down the exact order in which thousands of pieces of equipment would be moved. although not every detail was ironed out at the time of the move, the intentions and spirit of the sla have been documented and it will be completed during 2015. communicate developments and plans during the planning and development for the data center migration project, we recognized that it would be important to communicate any changes to the libraries’ systems availability to our users. its also recognized the need to communicate such changes. both its and the libraries took a many-pronged approach to communicating developments and plans related to the migration. within the libraries we shared updates at library faculty meetings as well as meetings of the library policy group (the dean’s administrative policy team). we sought feedback from many groups on proposed move dates, establishing intersession as the preferred time to move any libraries’ servers that would affect access to resources used by faculty or students. as the moves got closer the communication efforts were ramped up. within the libraries, we posted alerts on the libraries’ webpage that linked to charts indicating what services would be unavailable and when. we also included slides on the libraries’ main webpage with the same information. the same slide was posted on all three libraries’ flat-screen monitors, on which we post important news and dates. we sent mass emails to all libraries’ staff that reminded them when services would be down. staff members who were responsible for specific services made an effort to contact their customers directly. for example, the head of access services contacted information technology and libraries | december 2015 28 faculty members about the scheduled interruptions of ares, our electronic resources reserves system. some of the downtime affected just users, and other downtime also affected staff who could not work in the ils during the move. we planned alternate activities for staff members who could not work during the down time and had a productive division clean up day instead. its also made great efforts to communicate to the university community about the moves and any potential downtime. their efforts included mass emails to all faculty, staff, and students. its created and posted slides to the libraries’ flat screen monitors, as well as other monitors throughout the university. its also formed a team of liaisons from each school and college, using that group as yet another conduit to communicate changes. they shared draft schedules, seeking input on the effect of downtime on the university’s functions. leverage economies of scale one of the challenges of maintaining a distributed data center environment is that each system administrator or unit had to manage its own servers singlehandedly. in the case of the libraries at ualbany, we had moved in the direction of using the power of virtualization to manage many of our servers. virtualization refers to the process of creating virtual servers within one physical server, thereby multiplying the value of a single server many times. the libraries had virtualized a number of library servers, saving money by not having to purchase additional costly physical servers. however, its, with its greater purchasing power, was using more current and advanced virtualization software, hardware, and services than the libraries. its created a suite of services that allows system administrators access to the virtual environment so they can manage their virtual servers from their own offices. by moving into their virtual environment (iaas), the libraries are able to leverage the economies of scale presented by their environment. conclusion the consolidation of distributed data centers or server rooms on university campuses offers many advantages to their owners and administrators, but only minimal disadvantages. the university at albany carried out a decade-long project to design and build a state-of-the-art data center. the libraries participated in a two-year project to migrate their servers to the new data center. this included the hire of a data center migration consulting firm, the development of a migration plan and schedule for the physical move that took place late summer 2014. the authors have found that there are many advantages to consolidating data centers, including taking advantage of economies of scale, an improved physical environment, better backup services and security systems, and more. lessons learned from this experience include the value of participating in the process, reviewing migration schedules carefully, clarifying the costs of consolidation, contributing to the development of an sla, and communicating all plans and developments to the libraries’ customers, including faculty, staff, and students. as other university libraries consider the possibility of consolidating their data centers, the authors hope that this paper will provide some guidance to their efforts. data center consolidation at the university of albany | mugridge and sweeney | doi: 10.6017/ital.v34i4.8650 29

core metadata, combined with the characteristics and forms of intangible cultural heritage, this article explores the metadata for intangible cultural heritage in knowledge organizations based on relevant resource description standards. the wuhan woodcarving ship model is presented as an example of national intangible cultural heritage to control the application of metadata in intangible cultural heritage knowledge organizations. new ideas are provided for the digital development of intangible cultural heritage. introduction intangible cultural heritage includes traditions or living expressions inherited from our ancestors and passed on to our descendants. digital storage and presentation of intangible cultural heritage resources is an inevitable requirement for the protection of china’s long history and its culture in the information age. with the rapid development of artificial intelligence and big data, all kinds o f massive data in the internet age are expanding, necessitating the development of a database platform for the inheritance and protection of intangible cultural heritage. at the same time, organizations must consider how to deal with the intangible cultural heritage using complex data. searching for data and visualizing the relationship with intangible cultural heritage is a current research hotspot. however, at this stage, there are still some problems in the construction of digital resources of intangible cultural heritage in china, such as the establishment of accurate and interoperable metadata. in this process, the diversity and uniqueness of intangible cultural heritage items needs to be fully considered, including the subsequent integration of digital resources and its existing digital resource system of intangible cultural heritage in china. therefore, the construction of the intangible cultural heritage resource database is not only to simply organize and list the data, but more importantly, to reveal the relationships between the knowledge content and resources in the intangible cultural heritage field and to build a thorough and relevant knowledge system. research status at home and abroad metadata is data that describes the attributes of a certain type of resource (or object). metadata can be used to locate and manage the resource and display information about it.1 metadata can also be structured data used to describe online information resources and strengthen the collection development, organization, and utilization of online information resources.2 from the perspective of knowledge organization, general metadata is used to describe the theme, content, and characteristics of information resources. the most common metadata format is dublin core mailto:fanqmy@hotmail.com

metadata, which is structured and descriptive. the creation of metadata standards in the field of intangible cultural heritage must first combine the basic concepts and characteristics of cultural heritage to extract specific attributes and provide element definitions that describe the basic characteristics of intangible cultural heritage resources, that is, core metadata. this is not easy to achieve since intangible cultural heritage is traditional art, music, folklore, etc. only by unifying intangible heritage resources of different expressions through metadata standards can a relatively standardized intangible cultural heritage resource library be formed. the visual resources association of america (vra) created the vra core metadata standard to describe art, architecture, prehistoric artifacts, folk culture, and other artistic visual resources in the network environment.3 in terms of intangible cultural heritage material, lan xuliu et al. proposed the vra core as the foundation format and added elements from the categories for the description of works of art (cdwa) as the extended element metadata format of digital cultural resources.4 a sculpture of abraham lincoln was used as the basis for the metadata format. the example explains the specific use method of the proposed metadata format in practice. the solution does not extend the core elements and there is an overall lack of flexibility as users cannot customize the required elements. b. murtha proposed a descriptive metadata architecture in the field of art and architecture, including the core category of ontology id, and added a controlled vocabulary and classification system in the field of art and architecture to enrich the specific metadata model.5 it is mainly based on the theoretical discussion of metadata standards in this field, and there is no specific practice, but its method of formulating metadata from the perspective of user retrieval effects is worth learning. yi junkai et al. proposed the core metadata specification for digital museums as the basis for expansion, implemented the relevant methods in the metadata expansion rules, and finally formed a special metadata specification. 6 this metadata specification system can guarantee the basic and personalized description of resources. the metadata specification was developed and completed by the national museum of china. to keep this specification consistent with the metadata description of other metadata specifications at home and abroad, the description method refers to the iso-11179 standard.7 the national museum metadata specification contains seven element sets, 60 elements, and 342 restricted elements. the seven metadata element sets are: collection resource entity, data resource entity, responsible entity, business entity, transaction entity, relationship entity, and save entity. each metadata element of the museum’s digital resources defines several elements according to the concept of hierarchical structure; each element is defined and described by a group of attributes, such as name, version, logo, definition, type, and value range. there are 11 attributes of necessity, repeatability, lower-level elements, application scope, and annotations. the establishment of the metadata standard framework for museum digital resources is based on the digitization of museum collection resources. collection resources are the core of museum work, and the content of museum collection resources is the core component of digital resources.8 the digital resources of these collections are related to communication, transmission, storage, or business activities. based on the characteristics of china’s existing intangible cultural heritage information resources, li bo proposed a compatible and interoperable metadata model. the description of intangible cultural heritage information resources was created on the basis of information structure and semantic component analysis.9 the ontological characteristics of each intangible cultural heritage information and related documents, characters, objects, spaces, and other entities are included in the construction of the intangible cultural heritage metadata model, which combines china’s nonmaterial cultural heritage. the actual situation of the tangible cultural heritage database has a information technology and libraries june 2022 research on knowledge organization of intangible cultural heritage | qing, tan, sun, and chen 3 certain degree of international generality. ye peng compared the dc metadata standard system with the needs of china’s intangible cultural heritage protection, proposed a metadata standard based on intangible cultural heritage resources, and gave the scope of application. this metadata standard contains multiple core metadata, corresponding to the relevant elements in dc. 10 however, ye peng also pointed out that a major problem with this intangible cultural heritage metadata standard is that it is not compatible with china’s existing intangible cultural heritage database, such as information storage, digital mining, file retrieval, and multimedia distribution. connotation and design principles of intagible cultural heritage metadata connotation of intangible cultural heritage metadata the core metadata of this study will be designed based on the dc core metadata set, considering its versatility, scalability, easy conversion between metadata, interoperability between systems, and existing comparisons. universal dc metadata is the most influential and widely used metadata standard in the field of information resource description under the network environment. since the dc metadata standard is mainly aimed at the retrieval of network entity resources, it reveals common characteristics of digital entity resources but does not consider the cultural connotation and knowledge context of specific knowledge topics such as intangible cultural heritage.11 to reveal the originality of the object, the model proposed in this article will also combine the application and recording of china’s intangible cultural heritage items, reflecting the characteristics of specific intangible cultural heritage items, so as to facilitate compatibility and integration with existing information resources to form a unified interface standard with the existing intangible cultural heritage management system of the cultural sector, enabling the sharing of digital resources among cultural centers in different regions. design principles of intangible cultural heritage metadata the design of the metadata model of intangible cultural heritage information resources should be fully compatible with popular metadata standards. various metadata standards apply to different objects: dc is suitable for network resources, cdwa is suitable for artworks, and federal geographic data committee (fgdc) is suitable for geographic space. when it comes to digital collections, the national library of the netherlands was one of the first institutions in the world to respond, starting in 1994 with the decision to collect digital publications and working with publishers and it partners to make important contributions to digital collections research. the national library of the netherlands will develop a new global information network. the main approach of the system is to add dc data to all collected web pages. the new web page will require providers to add elements of the dc core set by themselves. once submitted, the national library of the netherlands’ search engine will use these dc elements to assist in retrieval. in recent years, the art museum community has adopted several metadata standards such as cdwa and vra core to describe their collections of art works. nam, y. j. and lee, s. m proposed a set of metadata elements customized to fit into the distinct context of smallscaled art museums in south korea.12 a small art museum in korea combines the existing cdwa, vra core, and dc standards and the proposed set of metadata elements is expected to support artistic resources. the metadata design of intangible cultural heritage resources should refer to the design cases of the netherlands and south korea. when applying the existing metadata standards, it is beneficial to fully reveal the characteristics of the described objects and decide whether to use the overall framework or the partial use, and must not be blindly used.13 information technology and libraries june 2022 research on knowledge organization of intangible cultural heritage | qing, tan, sun, and chen 4 the design of the metadata should connect with existing intangible cultural heritage information sources. at present, china should refer to the relevant standards of world intangible cultural heritage digital resources and establish a management system for intangible cultural heritage resources in line with the national, provincial, municipal and county levels. the relevant cultural management functional departments have also established relevant information systems to form a unified set of authoritative and standardized data. therefore, in terms of the elements and concepts used in the metadata model, special attention should be paid to the connection with these existing data models, so that as new resources are developed, these rich information sources can be shared through the mapping relationship between the elements. the metadata model should have good scalability and strong descriptive ability containing more elements. therefore, an element-rich metadata model has a strong influence on the organization and management of information resources and content disclosure. data inspection should be flexible. conversely, a metadata model with a lack of elements will be less flexible when technology is upgraded or user description requirements are expanded. a metadata model requires constant expansion and modification, and the practicality of the model will be greatly reduced. on the other hand, the design of the metadata model should have a mechanism that facilitates different types of users to expand elements according to different needs. the design of metadata can show the relationship between intangible cultural heritage resource entities. with the development of information resource description technology at home and abroad, a batch of metadata standards for various types of information resources have been formed. the metadata standards for china’s intangible cultural heritage should aim for compatibility and integrate existing world standards based on current results. the metadata should further be expanded and developed in accordance with preserving intangible cultural heritage works. the metadata standards for intangible cultural heritage archives should describe resources while displaying the greatest degree of versatility, compatibility, and standardization. therefore, combining the requirements of cultural heritage archiving and the characteristics of intangible cultural heritage, the dc metadata standard is used as the basic standard, and the advantages of other metadata standards are combined to determine the metadata standard of china’s intangible cultural heritage archives. intangible cultural heritage knowledge organization definition of intangible cultural heritage metadata through semantic analysis, the core attributes and concepts involved in metadata can be obtained, and the specificity of attributes and concepts can be improved through metadata standards, which can make users’ cognition, retrieval, and evaluation of information more accurate and effective. at the same time, the normative concepts and common attributes in existing metadata schemes should be quoted as much as possible. according to the attribute characteristics of the object, close and similar conceptual entities can be selected from one or more common metadata schemes, so that the element definition has versatility and standardization. for intangible cultural heritage, according to the attributes and characteristics of the object, close and similar conceptual entities are selected from one or more general metadata schemes to make the element definition universal and normative. in the “convention for the safeguarding of intangible cultural heritage," unesco pointed out that the types of intangible cultural heritage include oral traditions, performing arts, social practices, festivals, traditional handicrafts. based on the above-mentioned definitions of intangible cultural heritage types and the previous comparative research results on metadata information technology and libraries june 2022 research on knowledge organization of intangible cultural heritage | qing, tan, sun, and chen 5 standards of various countries, combined with the research results of scholars, the dc standard metadata name and standard affix library incorporates a set of intangible cultural heritage archive metadata containing 23 elements and extended elements (table 1). table 1. core metadata of intangible cultural heritage digital resources category standard

relationship of intangible cultural heritage digital achievements. on the one hand, a single standard removes barriers to sharing metadata caused by having intangible cultural heritage information resources with different hardware, different platforms, and different formats. on the other, it enables the digital resources of intangible cultural heritage to be shared online. for example, the china intangible cultural heritage digital museum (https://www.ihchina.cn/) uses unified metadata to design this section, which solves the problem of integration and sharing of different resources. the smooth conversion between new and old data is beneficial to the protection of intangible cultural heritage inventory data, avoiding duplication of work, and improving the efficiency and effectiveness of intangible cultural heritage storage. in addition, design of intangible cultural https://www.ihchina.cn/ information technology and libraries june 2022 research on knowledge organization of intangible cultural heritage | qing, tan, sun, and chen 6 heritage metadata standards must consider the versatility, compatibility, and individualization of the metadata system. description of digital resources of intangible cultural heritage through the analysis of the intangible cultural heritage project objects, we can provide content, management, resources, etc. these attributes can correspond to the elements of the metadata during the metadata design or serve as the semantic basis for the definition of the elements. the analysis and extraction of the core attributes and concepts of the object should firs t consider the full presentation of the object knowledge and resource content, and the concept should have a certain degree of specificity so that users can recognize, retrieve, and evaluate the information. secondly, it is important to refer to the normative concepts and general attributes in the existing metadata schemes as much as possible. according to the attribute characteristics of the object, select close and similar conceptual entities from one or more general metadata schemes, so that the element definition is versatile and standardized. therefore, the content description of intangible cultural heritage items should reflect unique cultural meanings and characteristics. at present, there are only general concepts such as name, category, subject, and region among several general metadata schemes. figure 1 shows the metadata framework of intangible cultural heritage. figure 1. metadata framework of intangible cultural heritage. in the content description, there are five elements which include names, types, subjects, regions, and protection levels as special attributes. in the metadata standard, the only elements that can be used in general are the name, subject, category, and region. the protection level means that the list of intangible cultural heritage is the object of national or provincial protection. the “national information technology and libraries june 2022 research on knowledge organization of intangible cultural heritage | qing, tan, sun, and chen 7 intangible cultural heritage declaration form” uses the five elements of content description, and then conducts resource description analysis based on the information organization structure of the intangible cultural heritage project object to construct intangible cultural heritage. th e framework covers the main attributes and definitions involved in intangible cultural heritage objects, as well as their connections and hierarchical relationships. in the description framework, in addition to the attributes and definitions specified by the dc metadata, a set of custom elements is also set.14 without changing the basic structure, users can customize elements according to standard needs to make the model extensible. in the description of related resources, entities related to intangible cultural heritage are divided into four categories: inheritors, object categories, resources, and organizations. among them, the inheritor-related attributes include six general attributes such as name, ethnicity, gender, region, age, and person profile. object category attributes include dance, song, art, literature, video, network, etc. for intuitive objects, you can refer to the use of artistic works to describe the category or the core category of visual materials, and the documentation and materials can use the metadata defined by dc. this model does not specify the use of attributes and concepts in metadata. in a specific metadata solution, these attributes and concepts can correspond to metadata element names, or they can be modifiers, values, or metadata element definition s, such as the inheritor of shadow puppetry is lin shimin. data association linked data is a technical specification recommended by the world wide web consortium (w3c). the relationship among linked data objects supports a greater degree of resource sharing and utilization, enabling users to efficiently and accurately locate needed resources on a larger scale. the release of linked data is to describe the metadata of cultural resources in the form of resource description framework (rdf). after forming semantic associations, intelligent retrieval and data discovery services are provided on the intelligent application platform, so as to ensure the visual presentation and data sharing of intangible cultural heritage digital resources in knowledge organizations. linked data publishing provides standardized data access specifications. the biggest advantage is that it can correlate data across platforms and establish links to different data, which is convenient for users to search for data in different repositories. as far as the content of intangible cultural heritage is concerned, linked data presents unstructured, semi-structured, and structured data on the internet in the form of rdf. rdf description refers to the transformation of metadata in resources into rdf triples through data and relationship mapping, and the formation of w3c-supported documents through semantic relationship construction. visual presentation refers to the visual presentation of relevant content by users through network search with the support of the network architecture. in essence, the release of digital resource data is to realize the rdf description and sharing of metadata for intangible cultural heritage metadata by multiplexing the relationship. its essence is the management application process of the database. the linked data publishing process of intangible cultural heritage resources consists of three steps: (1) converting the metadata of the repository into an rdf triple model and assigning a uri identifier to form an rdf document of linked data; (2) establishing a semantic relationship and building relational links to form semantic associations; and (3) mapping cultural resource data to the network through the uri access mechanism, and presenting data search results in a visual way information technology and libraries june 2022 research on knowledge organization of intangible cultural heritage | qing, tan, sun, and chen 8 through user sparq queries. although there are differences in the structure of different data publishing tools, metadata-based linked data publishing follows these basic steps. examples of metadata application of intangible cultural heritage knowledge organizations introduction to the wuhan wood carving ship model intangible cultural heritage project the wuhan woodcarving ship model is a unique art variety in chinese woodcarving craftsmanship, with a history of more than 2,000 years.15 according to the song dynasty’s the history of jin shi·zhang zhongyan: “the craftsman did not know how to build the ship. when the boat was built, the craftsmen did not know how to build it. the boat model made by zhang zhongyan. it was only a few inches long and was very delicate. the front and rear of the boat could be spliced well without glue. the other craftsmen were all amazed.” as early as the 12th century, there were people in china who could carve small boats several inches long as models for making ships. hubei woodcarving boats are a national intangible cultural heritage project but the art and craft faces challenges. like other intangible cultural heritage projects, development of the craftwork is weak. while younger generations in hubei may recognize the form of wooden carving boat, few are willing to learn this art and more young people have not even heard of it. in order to better honor this long-standing tradition, this article focuses on the characteristics of intangible cultural heritage digital resources, combined with the relevant theories of knowledge organization, an d adopts certain technical standards to organize the knowledge organization and construction of the metadata standards for hubei woodcarving ships. knowledge organization construction based on metadata to effectively use metadata in intangible cultural heritage, metadata specifications must be defined and described. rdf is metadata specification description language. it can semantically pay attention to the attributes of the ontology and the interrelationships between these attributes. by using rdf information, it can be easily exchanged between computers using different types of operating systems and application languages.16 rdf regulates the realization of semantics in a standardized and interoperable way. the web page can implement the invocation of rdf in a simple way, thereby facilitating the retrieval of network data and the discovery of related knowledge. in this paper, the metadata system needs to use rdf to define the attributes, so that it can be better transformed into a language that the computer can understand. intangible cultural heritage items have a certain relationship with inheritors, organizations, resource content, etc. in order to establish a complete intangible cultural heritage cultural resource database, these entities need to be described separately in rdf. wuhan woodcarving ship model metadata definition according to the rdf description, wuhan woodcarving ship model is used as a specific example to show the designed metadata scheme, that is, the relevant content of the example is filled into the defined resource description frame. for example, part of the rdf description of the wuhan woodcarving ship model intangible cultural heritage item can be found in the following code:

cultural heritage items and the integration of existing knowledge organizations and other types of resources for designing a set of more comprehensive and reasonable metadata standards with a certain degree of scalability and it is applied to the actual intangible cultural heritage knowledge organization. to effectively protect and use the digital resources of intangible cultural heritage, further research is needed for this study. additional discussion on updating and promoting existing metadata specifications as well as multidimensional aggregation of existing resources to achieve knowledge discovery is needed. through the integration of linked data and sharing existing digital resources, this article can encourage scholarship and conversation that leads to the preservation of china’s intangible cultural heritage. funding statement this work was supported by the hubei key laboratory of big data in science and technology. this work was also supported by the palace museum’s open project in 2021, research on the dissemination of intangible cultural heritage of the palace museum from the perspective of artificial intelligence. this subject has been funded by the mercedes-benz

internet access, but being available for free online is of little use if people cannot find open versions. a handful of tools have become available in recent years to help address this problem by searching for an open version of a document whenever a user hits a paywall. this project set out to study how effective four of these tools are when compared to each other and to google scholar, which has long been a source of finding oa versions. to do this, the project used open access button, unpaywall, lazy scholar, and kopernio to search for open versions of 1,000 articles. results show none of the tools found as many successful hits as google scholar, but two of the tools did register unique successful hits, indicating a benefit to incorporating them in searches for oa versions. some of the tools also include additional features that can further benefit users in their search for accessible scholarly knowledge. introduction the goal of open access (oa) is to ensure as many people as possible can read, use, and benefit from scholarly research without having to worry about paying to read and, in many cases, restrictions on reusing the works. however, oa scholarship helps few people if they cannot find it. this is especially problematic for green oa works, which are those that have been made open by being deposited in an open online repository even if they were published in a subscription -based journal. opendoar reports more than 3,800 such repositories.1 as users are unlikely to search each individual repository, an efficient search method is needed to find the oa items spread across so many locations. in recent years, several browser extensions have been released that allow a user to search for an open version of an article while on a webpage for that article. the tools include: • lazy scholar, a browser extension that searches google scholar, pubmed, europepmc, doai.io, and dissem.in. it has extensions for both the chrome and firefox browsers.2 • open access button, which uses both a website and a chrome extension to search for oa versions.3 • unpaywall, which also acts through a chrome extension to search for open articles via the digital object identifier.4 • kopernio, a browser extension that searches subject and institutional repositories and is owned by clarivate analytics. kopernio has extensions for chrome, firefox, and opera.5

et al. 83 https://doi.org/10.6017/ital.v38i3.11109 some of the tools offer other services, such as open access button’s ability to help the user email the author of an article if no open version is available, as well as integration with libraries’ interlibrary loan workflows. kopernio and lazy scholar offer to sync with a user’s institutional library to see if an article is available through the library’s collection.6 although other similar extensions might also exist, this article is focused on the four mentioned above based on the authors’ knowledge of available oa finding tools at the time of the project. literature review as noted above, scholars have indicated for several years a need for reliable and user-friendly methods, systems, or tools that can help researchers find oa materials. bosman et al. forwarded the idea of a scholarly commons—a set of principles, practices, and resources to enable research openness—that depends upon clear linkages between digital research objects.7 bulock notes that oa has “complicated” retrieval in that oa versions are often housed in various locations across the web, including institutional repositories (irs), preprint servers, and personal websites. 8 there is no perfect search option or tool, although some have tried creating solutions, such as the open jericho project from wayne state university, which is seeking to create an aggregator to search institutional repositories and eventually other sources as well.9 however, this lack of a central search tool can lead to confusion among researchers.10 nicholas and colleagues found that their sample of early career scholars drawn from several countries relied heavily on google and google scholar to find articles that interested them.11 many also turn to researchgate and other social media platforms and risk running afoul of copyright. the results of ithaka s+r’s 2015 survey of faculty in the united states reflect these findings to a certain extent, as variations exist between researchers in different disciplines.12 a majority of the respondents also indicated an affinity for freely accessible materials. as more researchers become aware of and gravitate toward oa options, the efficacy of various discovery tools, such as the browser extensions evaluated in this study, will become even more pertinent. previous studies on the findability of oa scholarship have focused primarily on google and google scholar.13 a few have assessed tools such as oaister, opendoar, and pubmed central.14 norris, oppenheim, and rowland sought a selection of articles using google, google scholar, oaister, and opendoar.15 while oaister and opendoar found just 14 percent of the articles’ open versions, google and google scholar combined managed to locate 86 percent. jamali and nabavi assessed google scholar’s ability to retrieve the full text of scholarly publications and documented the major sources of the full-text versions (publisher websites, institutional repositories, researchgate, etc.).16 google scholar was able to locate full-text versions of more than half (57.3 percent) of the items included in the study. most recently, martin-martin et al. likewise used google scholar to gauge the availability of oa documents across different disciplines.17 they found that roughly 54.6 percent of the scholarly content for which they searched was freely available, although only 23.1 percent of their sample were oa by virtue of the publisher. as of yet, no known studies have systematically evaluated the growing selection of open access tools’ efficiency and effectiveness at retrieving oa versions of articles. however, several scholars and journalists have reviewed these new tools, especially the more established open access button and unpaywall.18 these reviews were mostly positive, even as some acknowledged that the tools are not a wholescale solution for locating oa publications. despite pointing out these tools’ information technology and libraries | september 2019 84 limitations, reviewers voiced their hope that the oa finding tools could help disrupt the traditional scholarly publishing industry.19 at least one study has used the open access button to determine the green oa availability of journal articles. emery used the tool as the first step to identify oa article versions and then searched individual institutional repositories, followed by google scholar as the final steps.20 emery found that 22 percent of the study sample was available as green oa but did not say what portion of that was found by the open access button. emery did note that the open access button returned 17 false positives (six in which the tool took the user to the wrong article or other content, and 11 in which it took the user to a citation of the article with no full text available). she also found at least 38 cases of false-negative returns from the open access button, or articles that were openly available that the tool failed to find. the study did not count open versions found on researchgate or academia.edu. methodology oa finding tools this study compared the chrome browser extensions for google scholar and four oa finding tools: lazy scholar, unpaywall, open access button, and kopernio. each extension was used while in the chrome browser to search for open versions of the selected articles and the success of each extension in finding any free, full version was recorded. the authors did not track whether an article was licensed for reuse. for the four oa finding tools, the occurrences of false positives (e.g., the retrieval of an error page, a paywalled version, or the wrong article entirely) were also tracked. false positives were not tracked for google scholar, which does not purport to find only open versions of articles. data collection occurred over a six-week period in october and november 2018. the authors used web of science to identify the test articles (n=1,000) with the aim of selecting articles that would give the tools the best chance for finding a high number of open versions. articles selected were published in 2015 and 2016. these years were selected in order to try to avoid embargoes that might have prevented articles being made open through deposit. the articles were selected from two disciplines: applied physics and oncology, both of which have a large share in web of science and come from a broader discipline with a strong oa culture.21 each comparison began with searching the google scholar extension by article doi or title if a doi was not available. all versions retrieved by google scholar were examined until an open version was located or until the retrieved versions were exhausted. the remaining oa tools were then tested from the webpage for the article record on the journal’s website (if available). if no journal page was available, the article pdf page was tested. all data were recorded in a shared google sheet according to a data dictionary. searches for open versions of paywalled articles were performed away from the authors’ universities to ensure the institutions’ subscriptions to various journals did not impact the results. authors were limited in the number of articles they could search each day as some tools blocked continued use, presumably over concerns of illegitimate web activity, after as few as 15 searches. study limitations this methodology might have missed open versions of articles, even using these five search tools. although studies have found google scholar to be one of the most effective ways of searching for assessing the effectiveness of open access finding tools |auch schultz, azadbakht, et al. 85 https://doi.org/10.6017/ital.v38i3.11109 open versions, way has shown that it is not perfect.22 therefore, it is possible that this study undercounted the number of oa articles. the study tested the ability of oa finding tools to locate open articles from a journal’s main article page, not other possible webpages (e.g., the google scholar results page). this design may have limited the effectiveness of some tools, such as kopernio, which appear to work well with some webpages but not others. results overall, the tools found open versions for just less than half of the study sample (490), whereas they found no open versions for 510 articles. although lazy scholar, unpaywall, open access button, and kopernio all found open versions, google scholar returned the most with 462 articles (94 percent of all articles with at least one open version). open access button, lazy scholar, and unpaywall all found a majority of the open articles (62 percent, 73 percent, and 67 percent, respectively); however, kopernio found open versions for just 34 percent of the articles (see figure 1). figure 1. number of open versions found by each tool. it was most common for three or more of the tools to find an open version for an article, with just 48 found by two tools and 98 found by only one tool (see figure 2). information technology and libraries | september 2019 86 figure 2. number of articles where x number of oa finding tools found an open version. when looking at articles where only one tool returned an open version, google scholar had the highest results (84). open access button (4) and lazy scholar (10) also returned unique hits, but unpaywall and kopernio did not. open access button returned the most false positives with 46, or nearly 5 percent of all 1,000 articles. lazy scholar returned 31 false positives (3 percent), unpaywall returned 14 (1 percent), and kopernio returned 13 (1 percent). discussion the results for the oa search tools show that while all four options met with some success, none of them performed as well as google scholar. three of the tools—lazy scholar, open access button, and unpaywall—did find at least half or more of the open versions that google scholar did. it is important to note that open access button, which found the second fewest open versions, does not search researchgate and academia.edu because of legal concerns over article versions that are likely infringing copyright.23 this could have affected open access button’s performance. likewise, kopernio’s lower percentage of finding oa resources might relate to concerns over article versions as well. when creating an account on kopernio, the user is asked to affiliate themselves with an institution so that the tool can search existing library subscriptions at that institution. for this study, the authors did not affiliate with their home institutions when setting up kopernio to get a better idea of which content was open as opposed to content being accessible because of the tool connecting to a library’s subscription collection. if the authors were to identify assessing the effectiveness of open access finding tools |auch schultz, azadbakht, et al. 87 https://doi.org/10.6017/ital.v38i3.11109 with an institution, the number of accessible articles would likely increase, but this access would not be a true representation of what open content is discoverable. in addition, some tools might work better with certain publishers than others. for instance, kopernio did not appear to work with spandidos publications, a leading biomedical science publisher that publishes much of its content as gold oa, meaning the entire journal is published as oa. kopernio found just one open version of a spandidos article, compared to 153 by google scholar. this could be an unintentional malfunction either with spandidos or kopernio, which if fixed, could greatly increase the efficacy of this finding tool. however, open access button, lazy scholar, unpaywall, and google were able to find oa publications from spandidos at similar rates (135, 138, and 139, respectively) with no false positives. while none of the tools performed as well as google scholar, some of the tools were easier to use compared to google scholar. google scholar does not automatically show an open version first; instead, users often have to first select the “all x versions” option at the bottom of each record and then open each version until they find an open version. lazy scholar and unpaywall appear (for the most part) automatically, meaning users can see right away if an open version is available and then click a button once to be taken to that version. although open access button and kopernio do not show automatically if they have found an open version, users need to click a button on their toolbar once to activate each tool and see if the tool was able to find an open version. open access button also provides the extra benefit of making it easy for users to email authors to make their works open if an open version is not already available. relying on lazy scholar, unpaywall, or open access button first causes users no harm, and they can always rely on google scholar as a backup. whether all four tools are needed is questionable. for instance, a few of the authors found kopernio difficult to work with as it seemed to be incompatible with at least one publisher’s website and it introduced extra steps in downloading a pdf file. the fact that it also returned by far the fewest open versions—just 36 percent of the ones google scholar found and no unique hits—does not argue well for users to include it in their oa finding toolbox. also, while lazy scholar, unpaywall, and open access button all performed better on their own, the authors wonder what improvements could be created by combining the resources of the individual tools. conclusion the growth of oa finding tools is encouraging to see as far as helping to make oa works more discoverable. although the study showed that google scholar uncovered more articles than any of the other tools, the utility of at least two of the tools—lazy scholar and open access button—can still be seen in that both found articles not discovered by the other tools, including google scholar. indeed, using the tools in conjunction with one another appears to be the best method. and although open access button found the second fewest articles, the tool’s effort to integrate with interlibrary loan and discovery workflows, as well as its concern about legal issues are all promising for its future. likewise, kopernio might be a better tool for those interested in combining access to a library collection—which likely has a large number of final, publisher versions of scholarship—with their search for openly available scholarship. future studies can include newer oa finding tools that have entered the market, as well as evaluate the user experience of the tools. another study can also look at how well open access information technology and libraries | september 2019 88 button’s author email feature works. also, as open access button and unpaywall continue to move into new areas, such as interlibrary loan support, research could explore if these are more effective ways of connecting users to oa material as well as measure users’ understanding of oa versions they find. overall, the emergence of oa finding tools offers much potential for increasing the visibility of oa versions of scholarship, although no tool is perfect. however, if scholars wish to support oa through their research practices or find themselves unable to purchase or legally acquire the publisher's version, each of these tools can be valuable additions to their work. data statement the data used for this study has been shared publicly in the zenodo database under a cc-by 4.0

discussion conclusion data statement endnotes editorial and technological workflow tools to promote website quality | morton-owens 91 emily g. morton-owens editorial and technological workflow tools to promote website quality everard and galletta performed an experimental study with 232 university students to discover whether website flaws affected perception of site quality and trust. their three types of flaws were incompleteness, language errors (such as spelling mistakes), and poor style in terms of “ambiance and aesthetics,” including readable formatting of text. they discovered that subjects’ perception of flaws influenced their judgment of a site being highquality and trustworthy. further, they found that the first perceived error had a greater negative impact than additional problems did, and they described website users as “quite critical, negative, and unforgiving.”5 briggs et al. did two studies of users’ likelihood of accepting advice presented on a website. of the three factors they considered—credibility, personalization, and predictability—credibility was the most influential in predicting whether users would accept or reject the advice. “it is clear,” they report, “that the look and feel of a web site is paramount in first attracting the attention of a user and signaling the trustworthiness of the site. the site should be . . . free of errors and clutter.”6 though none of these studies focuses on libraries or academic websites and though they use various metrics of trustworthiness, together they point to the importance of quality. text quality and functional usability should be important to library website managers. libraries ask users to entrust them to choose resources, answer questions, and provide research advice, so projecting competence and trustworthiness is essential. it is a challenge to balance the concern for quality with the desire to update the website frequently and with librarians’ workloads. this paper describes a solution implemented in drupal that promotes participation while maintaining quality. the editorial system described draws on the author’s prior experience working in book publishing at penguin and random house, showing how a system that ensures quality in print publishing can be adjusted to fit the needs of websites. ■■ setting editing most people think of editing in terms of improving the correctness of a document: fixing spelling or punctuation errors, fact-checking, and so forth. these factors are probably the most salient ones in the sense that they are editor’s note: this paper is adapted from a presentation given at the 2010 lita forum library websites are an increasingly visible representation of the library as an institution, which makes website quality an important way to communicate competence and trustworthiness to users. a website editorial workflow is one way to enforce a process and ensure quality. in a workflow, users receive roles, like author or editor, and content travels through various stages in which grammar, spelling, tone, and format are checked. one library used a workflow system to involve librarians in the creation of content. this system, implemented in drupal, an opensource content management system, solved problems of coordination, quality, and comprehensiveness that existed on the library’s earlier, static website. t oday, libraries can treat their websites as a significant point of user contact and as a way of compensating for decreases in traditional measures of library use, like gate counts and circulation.1 websites offer more than just a gateway to journals; librarians also can consider instructional or explanatory webpages as a type of public service interaction.2 as users flock to the web to access electronic resources and services, a library’s website becomes an increasingly prominent representation of the library. at the new york university health sciences libraries (nyuhsl), for example, statistics for the 2009–10 academic year showed 580,980 in-person visits for all five locations combined. by comparison, the website received 986,922 visits. in other words, the libraries received 70 percent more website visits than in-person visits. many libraries conduct usability testing to determine whether their websites meet the functional needs of their users. a concern related to usability is quality: users form an impression of the library partly based on how it presents itself via the website. as several studies outside the library arena have shown, users’ experience of a website leads them to attribute characteristics of competence and trustworthiness to the sponsoring organization. tseng and fogg, discussing non-web computer systems, present “surface credibility” as one of the types of credibility affecting users. they suggest that “small computer errors have disproportionately large effects on perceptions of credibility.”3 in another paper by fogg et al., “amateurism” is one of seven factors in a study of website credibility. the authors recommend that “organizations that care about credibility should be ever vigilant—and perhaps obsessive—to avoid small glitches in their websites. . . . even one typographical error or a single broken link is damaging.”4 emily g. morton-owens (emily.morton-owens@med.nyu.edu) is web services librarian, new york university health sciences libraries, new york. 92 information technology and libraries | september 2011 happens when a page moves from one state to another. the very simple workflow in figure 1 shows two roles (author and editor) and three states (draft, approval, and published). there are two transitions with permissions attached to them. only the author can decide when he or she is done working and make the transition from draft to approval. only the editor can decide when the page is ready and make the transition from approval to published. (in these figures, dotted borders indicate states in which the content is not visible to the public.) a book publishing workflow involves perhaps a dozen steps in which the manuscript passes between the author, his or her agent, and various editorial staff. a year can pass between receiving the manuscript and publishing the book. the reason for that careful, conservative process is that it is very difficult to fix a book once thousands of copies have been printed in hardcover. by contrast, consider a newspaper: a new version appears every day and contains corrections from previous editions. a newspaper workflow is hardly going to take a full year. a website is even more flexible than a newspaper because it can be fixed or improved at any time. the kind of multistep process used for books and newspapers is effective, but not practical for websites. a website should have a workflow for editorial quality control, but it should be proportional to the format in terms of the number of steps, the length of the process, and the number of people involved. alternate workflow models this paper focuses on a contributor/editor model in which multiple authors create material that is vetted by a central authority: the editor. other models could be implemented with much the same tools. for example, in a peer-review system as is used for academic journals, there is a reviewer role, and an article could have states like “published,” “under review,” “conditionally accepted,” and so forth. most noticeable when neglected. editors, however, have several other important roles. for example, they select what will be published. in book publishing, that involves rejecting the vast majority of material that is submitted. in many professional contexts, however, it means soliciting contributions and encouraging authors. either way, the editor has a role in deciding what topics are relevant and what authors should be involved. additionally, editors are often involved in presenting their products to audiences. in book publishing, that can mean weighing in on jacket designs or soliciting blurbs from popular authors. on websites, it might mean choosing templates or fonts. editors want to make materials attractive and accessible to the right audience. together, correctness, choice, and presentation are the main concerns of an editor and together contribute to quality. each of these ideas can be considered in light of library websites. correctness means offering information that is current and free of errors, contradictions, and confusing omissions. it also means representing the organization well by having text that is well written and appropriate for the audience. writing for the web is a special skill; people reading from screens have a tendency to skim, so text should be edited to be concise and preferably organized into short chunks with “visible structure.”7 there is also good guidance available about using meaningful link words, action phrases, and “layering” to limit the amount of information presented at once.8 of course, correctness also means avoiding the kind of obvious spelling and grammar mistakes that users find so detrimental. choice probably will not involve rejecting submissions to the website. instead, in a library context it could mean identifying information that should appear on the website and writing or soliciting content to answer that need. presentation may or may not have a marketing aspect. a public library’s website may advertise events and emphasize community participation. as an academic medical library, nyuhsl has in some sense a captive audience, but it is still important to communicate to users that librarians understand their unique and highlevel information needs and are qualified to partner with them. workflow a workflow is a way to assign responsibility for achieving the goals of correctness, choice, and presentation. it breaks the process down into steps that ensure the appropriate people review the material. it also leaves a paper trail that allows participants to see the history and status of material. workflow can alleviate the coordination problems that prevent a website from exhibiting the quality it should. a workflow is composed of states, roles, and transitions. pages have states (like “draft” or “published”) and users have roles (like “contributor” or “editor”). a transition figure 1. very basic workflow editorial and technological workflow tools to promote website quality | morton-owens 93 effect was on the quality of the website, which contained mistakes and confusing information. ■■ methods nyuhsl workflow and solutions to resolve its web management issues, nyuhsl chose to work with the drupal content management system (cms). the ability to set up workflow and inventory content by date, subject, or author was a leading reason for that decision. other reasons included usability of the backend for librarians, theming options, the scripting language the cms uses (php), and drupal’s popularity with other libraries and other nyu departments.9 nyuhsl’s drupal environment has four main user roles: 1. anonymous: these are visitors to the nyuhsl site who are not logged in (i.e., library users). they have no permissions to edit or manage content. they have no editorial responsibilities. 2. library staff: this group includes all the staff content authors. their role is to notice what content library users need and to contribute it. staff have been encouraged to view website contributions as something casual—more akin to writing an e-mail than writing a journal article. 3. marketing team: this five-member group checks content that will appear on the homepage. their mandate is to make sure that the content is accurate about library services and resources and represents the library well. its members include both librarians and staff with relevant experience. 4. administrators: there are three site admins; they have the most permissions because they also build the site and make changes to how it works. two of the three admins have copyediting experience from prior jobs, so they are responsible for content approvals. they copyedit for spelling, grammar, and readability. admins also check for malformed html created by the wysiwyg (what you see is what you get) interface provided for authors, and they use their knowledge of other material on the site to look out for potential conflicts or add relevant links. returning to the themes of correctness, choice, and presentation, it could be said that librarian authors are responsible for choice (deciding what to post), the marketing team is responsible for choice and presentation, and the administrators are responsible for all three. an important thing to understand is that each person in a role has the same permissions, and any one of in an upvoting system like reddit (http://reddit .com), content is published by default, any user has the ability to upvote (i.e., approve) a piece of content, and the criterion for being featured on the front page is the number of approvals. in a moderation system, any user can submit content and the default behavior is for the moderator to approve anything that is not outright offensive. the moderator never edits, just chooses the state “approved” or the state “denied.” moderation is often used to manage comments. another model, not considered here, is to create separate “staging” and “production” websites. content and features are piloted on the staging site before being pushed to the live site. (nyuhsl’s workflow occurs all on the live site.) still, even in a staging/production system the workflow is implicit in choosing someone who has the permission and responsibility to push the staging site to the production site. problems at nyuhsl in 2007, the web services librarian position at nyuhsl had been open for nearly a year. librarians who needed to post material to the website approached the head of library systems or the “sysadmin.” both of them could post pages, but they did not proofread. pages that became live on the website stayed: they were never systematically checked. if a librarian or user noticed a problem with a page, it was not clear who had the correct information or was responsible for fixing it. often, pages that were found to be out-of-date would be delinked from other pages but were left on the server and thus findable via search engines or bookmarks. because only a few people had ftp access to the server, but authored little content, the usernames shown on the server were useless for determining who was responsible for a page. similarly, timestamps on the server were misleading; someone might fix one link on a page without reviewing the rest of it, so the page could have a recent timestamp but be full of outdated information. even after a new web services librarian started in 2007, problems remained. the new librarian took over sole responsibility for posting content, which made the responsibility clearer but created a bottleneck, for example, if she went on vacation. furthermore, in a library with five locations and about sixty full-time employees, it was hard for one person to do justice to all the libraries’ activities. if a page required editing, there was no way to keep track of whose turn it was to work on the document. there also was no automatic notification when a page was published. this made it possible for content to go astray and be forgotten. these problems added up to frustration for would-be content authors, a time drain for systems staff, and less time to create new content and sites. the most significant 94 information technology and libraries | september 2011 at the top of the homepage. their appearance should not be delayed, so any staff author can publish one. class sessions are specific dates, times, and locations that a class is being offered. these posts are assembled from prewritten text, so there is no way to introduce errors and no reason to route them through an approval step. figure 2 illustrates the main steps of the three cases. the names of the states are shown with arrows indicating which role can make each transition. unlabeled arrows mean that any staff member can perform that step. figure 3 shows how, at each approval step, content can be sent back to the author (with comments) for revision. although this happens rarely, it is important to have a way to communicate with the author in a way that is traceable by the workflow. figure 4 illustrates the concept of retirement. nyuhsl needed a way to hide content from library users and search engines, but it is dangerous to allow library staff to delete content. also, old content is sometimes useful to refer to or can even be republished if the need arises. any library staff user can retire content if they recognize it as no longer relevant or appropriate. additionally, library staff can resurrect retired content by resetting it to the draft state. that is, they cannot directly publish retired content (because they do not have permission to publish), but they can put it back on the path to being published by saving it as a draft, editing, and resubmitting for approval. figure 5 shows that library staff do not really need to understand the details of workflow. for any new content, they only have two options: keep the content in the draft state or move it on to whatever next step is available. all them can perform an action. the five marketing team members do not vote on the content, nor do they all have to approve it; instead, any one of them, who happens to be at his workstation when they get a notification, is sufficient to perform the marketing team duty. also, the marketing team members and administrators do not “self-approve”—no matter how good an editor someone may be, he or she is rarely good at editing her own work. nyuhsl’s workflow considers three cases: 1. most types of content are reviewed by one of the administrators before going live. 2. content types that appear on the homepage (i.e., at higher visibility) are reviewed by a member of the marketing team before being reviewed by an administrator. 3. two types of content do not go through any workflow. alerts are urgent messages that appear in red figure 2. approval steps figure 3. returning contents for edits figure 4. retirement editorial and technological workflow tools to promote website quality | morton-owens 95 this may sound like a large volume of e-mail, but it does not appear to bother library staff. the subject line of every e-mail generated by the system is prefaced with “[hsl site]” for easy filtering. also, every e-mail is signed with “love, the nyuhsl website.” this started as a joke during testing but was retained because staff liked it so much. one described it as giving the site a “warm, fuzzy feeling.” drupal modules nyuhsl developers used a number of different drupal modules to achieve the desired workflow functionality. a simple system could be achieved using fewer modules; the book using drupal offers a good walkthrough of workflow, actions, and trigger.10 of course, it also would be possible to implement these ideas in another cms or in a homegrown system. this list does not describe how to configure each module because the features are constantly evolving; more information is available on the drupal website.11 the drupal modules used include: ■■ workflow ■■ actions ■■ trigger ■■ token ■■ module grants ■■ wysiwyg, imce, imce wysiwyg api bridge ■■ node expire ■■ taxonomy role ■■ ldap integration ■■ rules ■■ results participation figure 6 shows the number of page revisions per person from july 14, 2009, to november 4, 2010. since many pages are static and were created only once, but need to be updated regularly, a page creation and a page update count equally in this accounting, which was drawn from the node_revisions table in drupal. it gives a general sense of content-related activity. a reasonable number of staff have logged in, including all of the librarians and a number of staff in key positions (such as branch managers). the black bars represent the administrators of the website. it is clear that the workflow system, while broadening participation, has hardly diffused primary responsibility of managing the website. the web services librarian and web manager have by far the most page edits, as they both write new content and edit content written by all other users. of the other options are hidden because staff do not have permission to perform them. the status of content in the workflow can be checked by clicking on the workflow tab of each page, but it also is tracked by notification e-mails. when the content enters a state requiring an approval, each person in that approving role gets an e-mail letting them know something needs their attention. the e-mail includes a link directly to the editing page. for example, if a librarian writes a blog post and changes its state from “draft” to “ready for marketing approval,” he or she gets a confirmation e-mail that the post is in the marketing approval queue. the marketing team members each get an e-mail asking them to approve the post; only one needs to do so. once someone has performed that approval, the marketing team members receive an e-mail letting them know that no further action is required. now the content is in the “ready for approval” state and the author gets another e-mail notification. the administrators get a notification with a link to edit the post. once an administrator gives the post final approval, the author gets an e-mail indicating that the post is now live. the nyuhsl website workflow system also includes reminders. each piece of content in the system has an author (authorship can be reassigned, so it is not necessarily the person who originally created the page). the author receives an e-mail every four months reminding him or her to check the content, revise it if necessary, and re-save it so that it gets a new timestamp. if the author does not do so, he or she will continue to get reminders until the task is complete. also, the site administrators can refer to a list of content that is out of date and can follow up in person if needed. note that reminders only apply to static content types like pages and faqs, not to blog posts or event announcements, which are not expected to have permanent relevance. figure 5. workflow choices for library staff users 96 information technology and libraries | september 2011 check the status by clicking on the workflow tab. this eliminates the discouraging mystery of having content get lost on the way to being published. ■■ identifying “problem” content: the node expire module has been modified to send e-mail reminders about stale content; as a result, this “problem” figure 7 shows the distribution of content updates once the web team members have been removed. it is clear that a small number of heroic contributors are responsible for the bulk of new content and updates, with other users logging on sporadically to address specific needs or problems. how editorial workflow addresses nyuhsl’s problems different aspects of the nyuhsl editorial workflow address different website problems that existed before the move to a cms. together, the workflow features create a clearly defined track that marches contributed content along a path to publication while always making the history and status of that content clear. ■■ keeping track of who wrote what when: this information is collected by the core drupal software and visible on administrative pages. (drupal also can be customized to display or sort this information in more convenient ways.) ■■ preventing mistakes and inconsistencies: this requires a human editor, but drupal can be used to formalize that role, assign it to specific people, and ensure nothing gets published without being reviewed by an editor. ■■ bottlenecks: nyuhsl eliminated bottlenecks that stranded content waiting for one person to post it by creating roles with multiple members, any one of whom can advance content to the next state. there is no step in the system that can be performed by only one person. ■■ knowledge: the issue of having too much going on in the library for one person to report on was addressed by making it easier for more people to contribute. drupal encourages this through its usability (especially a wysiwyg editor), and workflow makes it safe by controlling how the contributions are posted. ■■ “lost” content: when staff contribute content, they get e-mail notifications about its status and also can figure 6. number of revisions by user each user is indicated by their employee type rather than by name. figure 7. number of revisions by user, minus web team each user is indicated by their employee type rather than by name editorial and technological workflow tools to promote website quality | morton-owens 97 places web content in the context of other communication methods, like e-mail marketing, press releases, and social media.12 in her view, it is not enough to consider a website on its own; it has to be part of a complete strategy for communicating with an organization’s audience. libraries embarking on a website redesign would benefit from contemplating this larger array of strategic issues in addition to the nitty-gritty of creating a process to ensure quality. ■■ conclusions nyuhsl differs from other libraries in its size, status as an academic medical library, level of it staffing, and other ways. some aspects of nyuhsl’s experience implementing editorial workflow will, however, likely be applicable to other libraries. it does not necessarily make sense to assign editorial responsibility to it staff; instead, there may be someone on staff who has editorial or journalistic experience and could serve as the content approver. many universities offer short copyediting courses, and a prospective website editor could attend such a course. implementing a workflow system, especially in drupal, requires a lot of detailed configuration. developers should make sure the workflow concept is clearly mapped out in terms of states, roles, and transitions before attempting to build anything. workflow can seem complicated to users too, so developers should endeavor to hide as much as possible from nonadministrators. small mistakes in drupal settings and permissions can cause confusing failures in the workflow system. for example, a user may find him or herself unable to advance a blog post from “draft” to “ready for approval,” or a state change from “ready for approval” to “live,” and may not actually cause the content to be published. it would save time in the long run to thoroughly test all the possibilities with volunteers who play each role before the site is in active use. finally, when the workflow is in place, the website’s managers may find themselves doing less writing and fewer content updates. they have a new role, though: to curate the site and support staff who use the new tools. the concept of editing is not yet consistently applied to websites unless the site represents an organization that already relies on editors (like a newspaper)—but it is gaining recognition as a best practice. if the website is the most readily available public face of an institution, it should receive editorial attention just as a brochure or fundraising letter would. workflow is one way that libraries can promote a higher level of quality and perceived competence and reliability through their website presence. content is usually addressed by library staff without the administrators/editors doing anything at all. the administrators also can access a page that lists all the content that has been marked as “expired” so they know with whom to follow up. ■■ outdated content: some content may be outdated and undesirable to show the public or be indexed by search engines, but be useful to librarians. it also is not safe to allow staff to delete content, as they may do so by accident. these issues are addressed by the notion of “retiring” content, which hides content by unpublishing it but does not delete it from the system. ■■ future work the workflow system sets up an environment that achieves nyuhsl’s goals, structurally speaking, but social (nontechnology) considerations prevent it from living up to its full potential. not all of the librarians contribute regularly. this is partly because they are busy, and writing web content is not one of their job requirements. another reason is that some staff are more comfortable using the system than others, a phenomenon that reinforces itself as the expert users spend more time creating content and become even more expert. a third cause is that not all librarians may perceive that they have something useful to say. reluctant contributors have no external motivation to increase their involvement. it would be helpful to formalize the role of librarians as content contributors. there is presently no librarian at nyuhsl whose job description includes writing content for the website; even the web services librarian is charged only with “coordinating, designing, and maintaining” sites. ideally, every librarian job description would include working with users and would mention writing website content as an important forum for that. that said, it is not clear what metric could be used to judge the contributions fairly. it also is important to continue to emphasize the value of content contributions so that librarians are motivated and feel recognized. even librarians whose specialties are not outreach-oriented (e.g., systems librarians) have expert knowledge that could be shared in, say, a short article on how to set up rss feeds. workflow is part of a group of concerns being called “content strategy.” this concept, which has grown in popularity since 2008, includes editorial quality alongside issues like branding/messaging, search engine optimization, and information architecture. a content strategist would be concerned with why content is meaningful in addition to how it is managed. in her

higher education increasingly being online or having online components, it is important to ensure that online materials are accessible for persons with print and other disabilities. libraryrelated research has focused on the need for academic libraries to have accessible websites, in part to reach patrons who are participating in distance-education programs. a key component of a library’s website, however, is the materials it avails to patrons through vendor platforms outside the direct control of the library, making it more involved to address accessibility concerns. librarians must communicate the need for accessible digital files to vendors so they will prioritize it. in much the same way as contracted workers constructing a physical space for a federal or federally funded agency must follow ada standards for accessibility, so software vendors should be required to design virtual spaces to be accessible. a main objective of this study was to determine a method of increasing the visibility of vendor accessibility documentation for the benefit of our users. it is important that we, as service providers for the public good, act as a bridge between vendors and the patrons we serve. introduction the world wide web was developed late in 1989 but reached the public sector the following year and quickly gained prominence.1 around this same time (1990), the americans with disabilities act (ada) was also passed, so when it was written the role of the web had yet to take shape. websites and online content, while not included specifically in the ada, have been increasingly emphasized when institutions examine the accessibility of their resources for persons with disabilities. more recent legislation, as well as legal-settlement agreements (including with colleges and universities), have included—and even emphasized—the importance of accessible online content. researchers have argued that in requiring facilities to be accessible, ada must include digital accessibility.2 with higher education increasingly being online or having online components, it is important to ensure that online materials are accessible for persons with print and other disabilities, many of whom may have received more extensive support in primary and secondary schools. unless accessibility is pursued with purpose, the level of education and educational materials available for students with disabilities will be severely limited.3 literature review legislation and existing guidelines equal access to information for all patrons is a foundational goal of libraries. in higher education, accessible information and communications technology allows users of all abilities to focus on learning without undue burden.4 colleges and universities are required by law to provide enhancing visibility of vendor accessibility documentation | willis and o’reilly 13 https://doi.org/10.6017/ital.v37i3.10240 reasonable accommodations to allow an individual with a disability to participate fully in the programs and activities of the university. according to title ii of ada, discrimination on the basis of disability by any state or local government and its agencies is strictly prohibited.5 section 504 of the rehabilitation act of 1973 also prohibits discrimination on the basis of disability by any program or activity receiving federal assistance.6 the department of education stated, “public educational institutions that are subject to education’s section 504, regulations because they receive federal financial assistance from us are also subject to the title ii regulations because they are public entities (e.g., school districts, state educational agencies, public institutions of vocational education and public colleges and universities).” 7 this piece of legislation usually manifests itself in the physical learning space—wheelchair ramps, braille textbook options, interpreters, and more—but finds little application in the digital spaces of a university, especially in the library’s online research presence. this is an alarming revelation; much higher learning today takes place in an online environment, and inaccessible library resources are a contributing factor to challenges in higher education faced by users with disabilities. to be considered accessible, a digital space, such as a website, online-learning management system, or a research discovery layer, and any word documents, pdfs, and multimedia presented therein, should be formatted in such a way that it is compatible with assistive technologies, such as screen-reading software. a website should also be navigable without a mouse using visual or auditory clues. content on a website ought to be clearly and logically organized, with skip navigation links to bypass to the page’s main content. images should have alternative text descriptions, known as “alt text,” that is brief and informative, describing the content and role of the image. links should likewise have clear descriptions of the target page. these and similar considerations aim to help persons with impairments that may make reading a monitor or screen difficult.8 digital spaces like a research database are considered electronic information technology (eit). eit is defined as “information technology and any equipment or interconnected system or subsystem of equipment that is used in the creation, conversion or duplication of data or information.”9 recently this terminology has been converted to information and communications technology (ict) as per the final rule updating section 508 in early 2017, but the essence of what it means remains unchanged.10 legislation regarding digital accessibility exists, specifically section 508 of the rehabilitation act of 1973, but only federal agencies and institutions receiving federal aid are required to abide by these statutes. lawmakers considered technology as a growing part of daily life in 1998 and amended the rehabilitation act with section 508, requiring federal agencies to make their ict accessible to people with disabilities.11 in 2017, these standards were updated with a final rule that modernized guidelines for accessibility of future ict.12 any research databases or other applications used by college and university libraries to facilitate online learning would be considered ict and thereby subject to section 508 requirements. it is evident that libraries not only have legal reasons to comply with section 508, but ethical reasons as well because making library collections and services universally available is a core value of the library community.13 in addition to legislation, the world wide web accessibility initiative (wai) created the web content accessibility guidelines (wcag) in 1999 in response to the growing need for web accessibility and to promote universal design. these standards created for web-content creators and web-tool developers are continually updated as new technologies and capabilities emerge— with version 2.0 being released in 2008—and apply specifically to web content and design. many information technology and libraries | septmeber 2018 14 of these guidelines were absorbed by the 2017 refresh of section 508 of the rehabilitation act of 1973.14 with fourteen guidelines assigned priority levels 1–3, wcag 2.0, and subsequent revisions to date, offer three levels of conformance with digital-accessibility guidelines: level a, the most basic level, meaning all mandatory level 1 guidelines are met; level aa, meaning priority levels 1 and 2 are met; and level aaa, meaning priority levels 1–3 are met. these conformance levels are important because many ict vendors will make their claims to conformance with wcag standards by using provided wai icons or using statements that refer to the level of conformance.15 wcag 2.0 guidelines alone are not enough to determine fully if a website or other digital content is truly accessible. it partly depends on it having an intuitive layout for a variety of users, which can only be achieved through usability testing.16 it is crucial that librarians understand what is required for a product or service to be considered accessible, and a firm grasp of wcag 2.0 and its conformance levels will enrich a librarian’s understanding of web accessibility and section 508 regulations.17 a voluntary product accessibility template (vpat) is a self-assessment document that vendors are required to complete only if they wish to sell their products to the federal government or any institution that chooses to require them. the quality of vpats varies, but essentially they will list section 508 standards and for each specify whether they fully or partially support it, do not support it, or if the standard is not applicable. there is then a space for the vendor to provide an explanation for limitations. since these are voluntary self-assessments, these documents can sometimes be brief and incomplete, but even brief statements can be specific enough to relatively easily verify the claims of support. because libraries are portals to online content, including e-books, e-journals, databases, streaming media, and more, which are provided largely by third-party vendors, libraries face unique struggles when attempting to comply with federal regulations. notions of equality and equal access are inherent to libraries and important for the maintenance of a democratic society, which makes accessibility within libraries’ digital content a concerning ethics issue.18 having little control over how ict is designed, libraries still must figure out how to address accessibility needs within third-party ict. in 2012, the association of research libraries (arl) joint task force on services to patrons with print disabilities encouraged libraries to require publishers to implement industry best practices, comply with legal requirements for accessibility, include language in publisher and vendor contracts to address accessibility, and request documentation like vpats.19 the task force’s report was vital in the creation and direction of this study. existing literature and studies as library professionals, we may often make assumptions of the accessibility of a third-party resource when the reality is that greater importance is placed on design of a product; accessibility components are either being added as special features or are being included once the design work is completed.20 tatomir and durrance conducted a study on the compatibility of thirty-two library databases with a set of guidelines for accessibility they called the tatomir accessibility checklist.21 this list included checking the usability of these databases with a screen reader and braille renewable display. they found that 44 percent of the databases were inaccessible, with an additional 28 percent being only “marginally accessible,” based on their criteria. this suggests major problems exist within vendor database platforms.22 enhancing visibility of vendor accessibility documentation | willis and o’reilly 15 https://doi.org/10.6017/ital.v37i3.10240 building on this research, western kentucky university libraries conducted a study on vpats from vendors to determine how accessible seventeen of their databases were.23 the university libraries ran an accessibility scan on those databases and compared the results with the vendors’ vpats, finding that the templates from the vendors were accurate about 80 percent of the time. most of the vendors did not address the accessibility of portable document format (pdf) files in their vpat statements, though it was an important component of their services. pertinent to this study, western kentucky’s work looked for accessibility documentation on vendors’ websites , and when one was not found, contacted the vendors requesting this information. this study was unique for targeting vendor-supplied vpats rather than only examining the databases themselves or tutorials from vendors. as mentioned previously, this was only done for the libraries’ main database vendors. mune and agee published an article on the ebooks accessibility project (eap) funded by affordable learning solutions at the california state university system. in this project, the researchers compared academic e-book platforms to e-reader platforms used for popular trade publications. they gathered data on the top sixteen library e-book vendors at san jose state university based on patron usage and title and holdings counts. the results indicated that academic e-book platforms were less accessible than nonacademic platforms, largely because of hesitance in adopting the epub 3 format, which by default has superior navigation and document structure to pdf or html, common academic options.24 while this study focused solely on the accessibility of e-book materials, a method for contacting vendors used in the eap study was adapted for the current study, applied at a larger scale. the eap researchers attempted to locate the vendors’ vpats online, and they contacted the vendors at least twice to request a vpat or other accessibility statement when none was located. it is noteworthy that of the sixteen vendors, all but one (94 percent) provided eap with some form of accessibility documentation, though less than half (44 percent) had a vpat available.25 another study, by joanne oud, examined vendor-supplied database video tutorials. half of the twenty-four vendors examined in oud’s study had tutorials in formats that were not accessible by keyboard or screen reader. this was largely because many of these tutorials were flash-based.26 shockwave flash is neither accessible for persons with disabilities nor good for usability on modern browsers.27 oud’s findings suggest that tutorial content would be more widely accessible if they were placed in youtube or another platform that had transcripts and captions available. while the focus of the study was different from our own, it was similar in that oud examined the accessibility of vendor materials apart from the journals and collections. also, oud noted that to make use of vendor tutorials, the website on which they are housed must likewise be accessible and the videos easy to find, but this is often not the case.28 other studies suggest that vendor websites and platforms often impede access to information. vendor platforms often have inaccessible pdfs, or the links to the full-text options are not easily located. delancey’s study also found more than three-fourths of the vendors examined had images without alternative text and frames without titles, resulting in many users with visual impairments being left out of the content of these images and frames entirely. of particular note, however, was the finding that not one of the vendors in this study had all forms —buttons, search boxes, and other browser navigation tools—labeled correctly, leaving the sites difficult to navigate.29 beyond whether the information itself is accessible, the question inevitably arises, can information technology and libraries | septmeber 2018 16 the desired information even be reached? one way or another, the content on these platforms must be accessible and easy to find. part of the motivation behind the current study stems from what delancey put so well: “only one vendor (out of seventeen), project muse, had a publicly available vpat on their website, though 9 others supplied this documentation upon request in under a week.”30 the first step in improving accessibility of resources for our patrons is to discuss accessibility with them—to determine how accessible information resources are today and identify areas of need. if a vpat or, minimally, any form of an accessibility statement is not easily discoverable on a vendor’s website—even if it is available upon request—users with disabilities as well as enabled users are not able to benefit from this information. are the vendors making it a priority in this case? additionally, since 41 percent of the vendors delancey examined had no vpat at all, what can be done before and aside from reaching out to vendors and stressing the importance of accessibility and of making statements on accessibility easy to find? from legal responsibilities to the dismal reality of digital accessibility, the task of improving library service for patrons with disabilities is daunting, even with the empowering ethical drivers of the library value system. ostergaard created “strategies for acquiring accessible electronic information sources,” an incredible guide to begin creating a guide that helps librarians develop an accessibility plan informed by her own work committed to accessibility in her library. steps 3 and 4 of ostergaard’s strategies are particularly relevant to the current study. step 3, “communicating with vendors,” involves inquiring about the accessibility of electronic products in addition to asking about any future plans for accessibility of their product and requesting vpats or other vendor supplied accessibility documentation. step 3 also recommends that librarians request vendors meet wcag 2.0 best practices and to incorporate a clause in license agreements that clearly defines accessibility of their products as further demonstration of ded ication to accessibility. such communication, it is hoped, would also lead to improved product development.31 once vendors are contacted, ostergaard outlines in step 4 the importance of documenting vendor communication regarding digital accessibility and further suggests assigning a person or team to review information received. ostergaard’s library changed the name of their acquisitions budget to “access budget,” reallocating a portion of their budget to review existing subscriptions, purchase accessible replacements, or in some cases, convert materials to an accessible format. the documentation review allowed the library to make informed decisions about collections and service availability on behalf of library users, but no mention was made of involving users in this process. the article provided a letter template that encompassed the aforementioned concepts and a request for assessment documentation, such as vpats and official statements of compliance. the ostergaard template served as a foundation for the language used in vendor communication for the current study, particularly the vpat or other accessibility documentation request.32 there have been no studies that suggest a way to implement easily discoverable vendor accessibility documentation—even when said documentation is not readily available to the public on the vendors’ sites. delancey suggested creating “an open repository for both vendor supplied documentation, and the results of any usability testing,” but this was suggested for internal library use, not public dissemination.33 if this documentation is made more easily available, we can enhancing visibility of vendor accessibility documentation | willis and o’reilly 17 https://doi.org/10.6017/ital.v37i3.10240 increase patron involvement in the discussion of accessibility of vendor-supplied library resources. research methods library-related research has focused the need for academic libraries to have accessible websites, in part to reach patrons who are participating in distance-education programs.34 a key component of a library’s website is the materials it avails to patrons from vendors, like databases and database aggregators. since, however, these materials are accessed via vendor platforms, they are outside the direct control of the library, making it more difficult to address accessibility concerns. some vendors have put forward significant effort in addressing accessibility needs. some offer a built-in feature for text-to-speech for html files or provide documents in a variety of formats, including txt and mp3 files, thereby offering a format that works well with common screenreading programs, or providing a sound file directly. this is of particular benefit to patrons with print disabilities.35 other vendors, such as ebook central (formerly ebrary), have worked to eliminate their flash dependencies. this is recognized as a positive step toward making vendor content usable for all. streaming video and other nonprint-based library materials must also be accessible. a person with visual impairments may be able to hear the soundtrack of the video, but unless an accurate description is provided of what is being presented visually, he or she will miss out on such information, such as the names of those speaking. to complicate matters further, hearing impaired users of these databases will not be privy to what is verbalized unless accurate captions and transcripts, or an interpreter, is made available for the videos. captions and transcripts are sometimes made available, but can easily be incomplete or incorrect. for example, alexander street press provided closed captioning and transcripts for some collections but not others. even when the captions or transcripts existed, as with a video we tested from ethnographic videos online, it was of low quality, inscribing the word “object” as “old pics,” “house” as “mess,” and so forth. one vendor, docuseek, had subtitles to translate from spanish, but no closed captioning or transcript available. audio-impaired users could not make full use of the video because the subtitles did not include all information presented in the sound track. (transcripts can also be useful to visually impaired users using screen readers.) films on demand had better captions and transcripts, but did not include all the words on the screen in the transcript, such as the title. regardless of the medium there are multiple ways to provide accessible versions, but they are seldom automatic. librarians must communicate the need for accessible digital files to vendors so they will prioritize it. as long as libraries—one of their main customer groups—accept their offerings whether accessible or not for persons with disabilities, vendors have no reason to put great effort into making these improvements. as colker pointed out, commercial vendors are not required to comply with ada regulations under title ii or title iii.36 vendors may also face resource restrictions that hinder their ability to improve their platforms’ accessibility. 37 they are businesses, so it is natural that they would only commit a concerted effort to reformat and enhance their platforms and records if the benefits are expected to outweigh the costs; they must firstly be made aware of the issue, and know that it is important to libraries and their patrons. information technology and libraries | septmeber 2018 18 in much the same way as contracted workers constructing a physical space for a federal or federally funded agency must follow ada standards for accessibility, so software vendors should be required to design virtual spaces to be accessible. this comparison was made by the department of education more than twenty years ago, and has the added benefit of greatly reducing the need for accommodation after the fact.38 according to cardenes, “at a minimum, a public entity has a duty to solve barriers to information access that the public entity’s purchasing choices create.”39 oswal stressed the importance of integrating the blind user experience into the development of databases from the beginning, as well as finding steps useful for guiding library users after the fact. merely following the rules set out in federal regulations is not enough to provide exemplary service to library patrons. the patrons as well must be involved in the process to fully address accessibility needs.40 process and findings the first objective of this study was to gain a better understanding of the accessibility of our library’s vendor-provided digital resources through the review of vendor-provided accessibility documentation. the second objective of this study was to determine a method of increasing the visibility of accessibility documentation for the benefit of our users and to communicate to them our commitment to improving service to users with disabilities. with a digital collection consisting of 270 databases, more than 750,000 e-books and e-journals, and more than 12 million streaming media titles, it was difficult to identify an appropriate sample. we needed a collection that would best serve as an illustrative swatch of our library’s digital holdings, and more importantly, a collection that would have the largest impact on our users. we also needed to establish a strategy for obtaining accessibility documentation regarding third-party content as well as create a delivery method for the vpats and other documentation we discovered in the course of our study. similar to other institutions, our library maintains a directory of the most used and most useful databases on the library’s homepage in the form of the a–z list (http://libresources.wichita.edu/az.php). determinations of usefulness are based on input from our reference librarians, who connect with user needs directly, whereas use comes from annual usage statistics compiled as per standard library procedures. users can browse this directory by subject, search by title, and sort by database type (full-text, streaming media, etc.), and the a-z list is a convenient place for users to begin their research. the directory also served as a convenient place to begin this study as it presented us with a sample that not only reflected the needs and habits of our patrons, but an excellent and diverse list of vendors to work with. beginning with a list of all subscribed databases (270 in 2016) exported directly from the a–z list’s backend, we sorted the list by vendor and determined that 74 vendors would be investigated. university materials indexed by the directory (i.e., institutional repository and libguides) were excluded from this study. as visibility of accessibility documentation is of concern to this study, our investigation began by visiting the database or vendor’s site and conducting a web search to obtain any information about accessibility. we were looking for mentions of the following keywords: “section 508” or “section 504,” “w3” or “wcag,” “vpat,” “ada,” and simply “accessibility.” some sites were intuitive: thirty-four vendors (45 percent) had statements that were found online. examples of commonly used documentation, which for the purposes of this study will be referred to as http://libresources.wichita.edu/az.php enhancing visibility of vendor accessibility documentation | willis and o’reilly 19 https://doi.org/10.6017/ital.v37i3.10240 accessibility statements, included “accessibility policy,” “section 508 compliance,” or “accessibility statement.” of those thirty-four vendors who posted accessibility documentation online, eleven provided a vpat or a link thereto in their accessibility statements. if we could not find an accessibility statement on the site, vendors were contacted first via email requesting information and documentation regarding the accessibility of their product using a form letter inspired by the ostergaard template.41 this email address was either found online— likely the “contact us” or technical support email links—or originated in the list of vendors’ contacts maintained in the library management system if another contact could not be found. if a response was not received within thirty days, the vendors were contacted a second time, a suggestion gleaned from mune and agee’s work.42 after all vendors included in the study had been contacted, any who did not provide a vpat were contacted a final time with a specific request for a vpat. for vendors who responded they could not provide a vpat or other accessibility statement, we used a screenshot of their response as documentation. the form letter (see appendix a) used in the current study made it known to vendors that their response would be posted publicly for the benefit of our users. twelve of the remaining vendors responded to our email inquiries with vpats and seven vendors responded with other accessibility documentation. figure 1. results of vendor query for accessibility documentation. in total, eleven vpats (15 percent) were found online and vpats from twelve vendors (16 percent) were received in response to our emailed request. twenty-three vendors (31 percent) had other accessibility documentation available online, while seven vendors (9 percent) provided other accessibility documentation in response to email inquiries. eight vendors (11 percent) other accessibility documentation found online 31% other accessibility documentation received 9% no official statement 11% did not respond 18% vpats found online 15% vpats received 16% vpats 31% results of vendor query for accessibility documentation information technology and libraries | septmeber 2018 20 responded they had no official statements or documentation to offer, and thirteen vendors (18 percent) did not respond (see figure 1). with the documentation compiled, we needed to establish an appropriate delivery system that would make this accessibility information visible to library users and therefore further the accessibility efforts. our collection cross-section, the a–z list, was chosen because of its prominence in our library’s online research presence as a suitable location to not only store but to convey this documentation to users. we created a clickable icon to be embedded into the databases’ entries in our a–z list created in libguides (a springshare product). clicking the icon would take the user to the vendor’s statement page, directly to the vpat, or to a page we created in libguides to store screen captures of vendor emails and vpats we received as attachments. if a vpat was available, we linked to it above any other documentation because vpats present a more rigorous analysis of the accessibility of third-party-created ict. libguides was determined to be a suitable place to house this documentation not only because it made the information easy to find for patrons, but also because springshare built libguides in an increasingly accessible manner and has documented its efforts using vpats for each product (see appendix b). further study it is expected that some of the information provided by the vendors is incomplete or inaccurate, even despite their best efforts, so the information we provide to patrons from and about the vendors might at times lead our patrons astray. we briefly examined the vpats acquired through this project to inform our work moving forward and found errors in at least half of them. some vendors claimed that skip navigation was available when none was found, while another would have benefitted from it but said it was “not applicable.” others were too brief to be useful, as no explanations were given for their claims. building on this current research, we intend, in collaboration with patrons with disabilities, to further verify the accuracy of key statements made by vendors in their vpats and other accessibility documentation. this analysis will give concrete feedback to vendors on how their sites could be further improved. as stated earlier, giving patrons access requires more than following a set of guidelines; it requires dialog to ensure their needs are fully met.43 it requires more than making the available documents accessible, but also testing the platform used to retrieve the documents for accessibility. as one author put it so well, “a lack of technological access is a solvable problem, but only if it is made a priority.”44 as vendors are not directly subject to enforcement of section 508 and other statutes regarding accessibility of the products they provide to libraries, vpats are truly voluntary. as such, the level of effort and detail of the product assessments are inconsistent and accuracy of the documentation is questionable. we intend to continue to be involved in the digital-accessibility initiative in part through our analysis of our digital-library presence, utilizing user input and expanding their role in improving the user experience. this would enable us to further improve our libraries’ service to users with disabilities. if we, as library professionals and institutions, stand together and each say our part, vendors will realize this is an important issue to address. also, it is important that we, as service providers for the public good, act as a bridge between these vendors—who at times do not avail good service information to their customers—and the patrons we serve. it may be a small step, but providing links to the vpats and other accessibility statements from vendors right where the patrons need enhancing visibility of vendor accessibility documentation | willis and o’reilly 21 https://doi.org/10.6017/ital.v37i3.10240 them is an important step in meeting the patrons where they are and showing them help is available. we can show patrons we care and will work with them to improve the now limited accessibility of not only scholarly information itself, but even of the platforms in which they are housed. information technology and libraries | septmeber 2018 22 appendix a: accessibility documentation request email template subject line: vpat request thank you for the information

introduce a gold-standard pashto dataset and a segmentation app. the pashto dataset consists of 300 line images and corresponding pashto text from three selected books. a line image is simply an image consisting of one text line from a scanned page. to our knowledge, this is one of the first open access datasets which directly maps line images to their corresponding text in the pashto language. we also introduce the development of a segmentation app using textbox expanding algorithms, a different approach to ocr segmentation. the authors discuss the steps to build a pashto dataset and develop our unique approach to segmentation. the article starts with the nature of the pashto alphabet and its unique diacritics which require special considerations for segmentation. needs for datasets and a few available pashto datasets are reviewed. criteria of selection of data sources are discussed and three books were selected by our language specialist from the afghan digital repository. the authors review previous segmentation methods and introduce a new approach to segmentation for pashto content. the segmentation app and results are discussed to show readers how to adjust variables for different books. our unique segmentation approach uses an expanding textbox method which performs very well given the nature of the pashto scripts. the app can also be used for persian and other languages using the arabic writing system. the dataset can be used for ocr training, ocr testing, and machine learning applications related to content in pashto. background the ocr technology for printed modern latin scripts is a largely solved problem, as both character and word accuracies typically reach greater than 95%. most well-known commercial ocr systems include abbyy, omnipage, and adobe acrobat ocr engine (licensed from iris), while open source systems have tesseract, ocropus, and kraken. ocr technology for other languages and scripts, including arabic scripts and traditional chinese, is still not satisfactory despite the fact that ocr research on these languages has been ongoing since the 1980s. an east asian librarian in 2019 wrote to the author: i am just back from the annual aas (association for asian studies) and ceal (council on east asian libraries) meetings. this year, prof. peter bol of harvard hosted a 2-day digital tech expo there to promote digital humanities . . . i spent 1 day on the dh sessions, where scholars constantly mentioned chinese ocr as a conspicuous and serious block on their path to assessing “digitized” textual collections. if you and your team succeed, it will surely help the eas scholarly community a lot.1 mailto:yhan@email.arizona.edu mailto:rychlik@math.arizona.edu information technology and libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 2 sturgeon, who has directed the chinese text project since 2005, stated that ocr of premodern chinese texts presents challenges distinct from ocr of modern documents and premodern documents in other languages, because training data is typically not available and a natural approach to improving accuracy is to train using data extracted from real images of text in the same historical writing style.2 sturgeon utilized both imperfect ocr software and allowed users to manually key in corresponding text via a crowdsourcing approach to gradually improve the quality of transcriptions.3 in 2018, the authors received a grant award from the national endowment for the humanities (neh) to develop ocr and a software prototype for an open-source global language databank for pashto and traditional chinese. activities included fundamental research and software implementation of new ocr technology for the two languages. for the past two years, we have been engaged in all aspects of ocr research in pashto, persian, and chinese scripts, including assessing current technology and systems, reviewing and building datasets, and researching and implementing segmentation algorithms and machine learning models involving neural networks. languages, scripts, and writing systems people in the world read, write, and speak a handful of major languages. of those, reading and writing is accomplished through the use of several types of scripts: latin, chinese, arabic, and devanagari. languages and scripts are very complex topics in regard to origin, structure, and use. they evolve due to influencing and being influenced by each other. a script is defined as “a collection of letters and other written signs used to represent textual information in one or more writing systems,” where a writing system is a common communication method to allow people to exchange information through a medium such as paper.4 the first requirement in a writing system is letters or other written signs. a common writing system can use an alphabet, syllabary, or logography. specifically, the latin and arabic writing systems use alphabets, where an alphabet is a standardized set of letters. combination of letters makes a word. another approach is to use a logogram. chinese characters (including japanese kanji and korean hanja) are logograms. in the alphabet and syllabic systems, individual characters represent sounds only, while in the logographic system each logogram represents a word or a phrase. one script, such as latin and arabic, may be used for several different languages, while some languages use several scripts. latin script is used in western europe, most of eastern europe, and across north and south america. arabic script was adopted by the west asian, middle eastern, and near african regions. in contrast, the japanese use three scripts: the hiragana and katakana syllabaries and the kanji logogram. the next critical feature in a writing system is the order in which to read and write. a writing system has two directions: horizontal and vertical. almost all writing systems are written vertically from top to bottom (ttb). bottom-to-top (btt) writing systems do exist. the philippines traditional scripts, the tagalog (baybayin), hanunóo, buhid, and tagbanwa are in limited use today. they are written from btt.5 within the ttb method, four possibilities exist: 1. left to right (ltr) first and ttb: this method refers to writing a horizontal line starting from the top left of a page, continuing to the right, and returning to the next line all the way from top to bottom. the latin writing system uses this variation. the current chinese writing system uses this order as well. information technology and libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 3 2. right to left (rtl) first and ttb: this method refers to writing a horizontal line starting from the top right of a page, continuing to the left, returning to the next line and all the way from top to bottom. arabic writing systems, such as arabic, persian, and pashto, use this order. 3. ttb first and rtl: this method refers to writing a vertical line starting from top right of a page, continuing to the bottom, and returning to the next line all the way from right to left. this method was widely used in traditional chinese (before the 1950s) and traditional japanese materials for thousands of years. it is still used in chinese calligraphy, and occasionally can be found in materials published in chinese. 4. ttb first and ltf: rarely used by a writing system. one of the examples is the manchu script.6 the nature of the scripts and the writing systems may require different algorithms and considerations when we deal with ocr technology, including preparing datasets, segmentation, and performing ocr in computer vision. pashto pashto (پښتو ), alternatively spelled as pushto, pukhto, or pakhto, historically as afghani (افغاني ), is one of the two official languages of afghanistan (the other is dari/farsi/persian). it is also spoken as a regional language in pakistan. pashto is spoken by 40 to 60 million people in afghanistan and pakistan. 7 the arabic script writing system is used for writing arabic, persian, and pashto languages in a cursive style. arabic, persian, and pashto are totally different languages, though they use almost the same alphabets within the same writing system. the pashto alphabet is a modified form of the arabic alphabet. it consists of 45 letters and four diacritic marks and includes all 28 letters from the arabic alphabet. the pashto alphabet includes all 32 letters from the persian alphabet, of which 28 letters are from the arabic alphabet. the romanization of pashto consists of several standards including the american library association (ala) and library of congress (lc) ala-lc romanization, bgn/pcgn, din 31635, iso233, and arabtex. details of romanization of pashto letters with their initial, medial, final forms, and the ala-lc rules are available at library of congress’s website.8 the need for datasets the authors are currently engaging in ocr research, and have applied machine learning (ml) models and methods such as convolutional neural networks (cnn) and recurrent neural networks (rnn). the advance of ml models and multiple methods has achieved great improvements in many fields. for instance, the most well-known event in ml occurred when an ai program named alphago defeated the world go champion in 2015. open-source ocr systems tesseract and ocropus both released their ocr systems using the rnn models in 2014 and 2018. these models and methods rely heavily on datasets for training, improvement, and evaluation. similarly, alphago uses datasets for training and evaluations. good and comprehensive datasets are critical to the success of an ml model and/or method. the most well-known dataset is the mnist database which contains a training set of 60,000 images and a test set of 10,000 images (28 × 28 pixels) of handwritten digits (0–9). the dataset is widely used for training and testing in ml as the gold-standard dataset for ml techniques and pattern recognition. information technology and libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 4 related datasets currently, few pashto datasets are available as open access. while there are other pashto datasets mentioned in the literature, we have not found one that provides a one-to-one mapping of line images to texts. a search on github has one result showing a raw text dataset containing content in pashto scraped from the web. however, this dataset is of little use in the case of training ml models for ocr, because it has no corresponding text. the computer science department of the national university of computer and emerging sciences (nuces) peshawar campus has been working on pashto ocr since 2006, and its research has created a pashto image-to-ligature dataset titled fast-nu dataset, containing 4,000 images of 1,000 unique ligatures in a variety of font sizes.9 the creators of this dataset have kindly sent us the pashto image-to-ligature dataset. a recent paper discussed the use of deep learning architectures for ocr in pashto with the development of a bigger dataset based on the fast-nu dataset including contours, negative, and rotated images.10 ali developed a database recording pashto digits from 25 male and 25 female native pashto speakers for automatic speech recognition. unfortunately, the authors had difficulties in downloading this dataset.11 khan et. al. designed a database encompassing a total of 4,488 images (102 distin guishing samples for the 44 pashto letters). this approach is very close to that of the fast-nu dataset.12 we are not sure if they are very similar, as we have not found a way to download and evaluate the dataset. another article describes offline pashto ocr using ml which tested more than 5,000 images in the dataset.13 the article describes its “extraction of lines containing pashto content,” but these “lines containing pashto content” have no specific resource or link to check. rawan and han compiled a pashto–english dictionary, which is open accessible through its website and an android app.14 in the past decade of working with afghan materials, han and rawan found several existing pashto language dictionaries online but encountered several issues related to standardized spelling, pronunciation, romanization/transliteration, and limited content. this improved dictionary contains over 12,000 entries of pashto words; each entry has a pashto word and corresponding english meanings. the pashto–english dictionary has been created with the following objectives in mind: a) standardized spelling and vocabulary, b) standard pronunciation, and c) standardized romanization with the ala–lc romanization scheme. other published pashto dictionaries either use one of the above or a combination of a few romanization systems. this dataset is available for noncommercial use upon reasonable request. two datasets but in different languages (arabic and persian) were produced by the open islamicate texts initiative, available in github (https://github.com/openiti/ocr_gs_data).15 both arabic and persian datasets have scans of original books from the premodern and corresponding texts.16 for example, its persian datasets came from page images from three persian books. these pages were segmented into separated line images and the line images were transcribed with corresponding persian texts. https://github.com/openiti/ocr_gs_data information technology and libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 5 building a pashto dataset our dataset creation methodology consists of three phases: • the first is to select pashto publications from our largest digital afghan collections. the focus was to have a language specialist who selected publications varying in fonts, original quality, and publication years. • the second phase is to use our segmentation app to produce line images from page images of the selected titles. because of the nature of pashto alphabets, we took a different segmentation approach involving expanding textboxes. this approach produced positive outcomes. • the final phase is to generate gold-standard text from corresponding line images involving human key-in and final review. we originally hoped that ocr generated text could increase productivity. unfortunately, the text produced from the current open-source ocr system tesseract 4.x was not useful. a persian ph.d. student was hired to complete the one-to-one key-in. finally, the author and his colleague reviewed the dataset. data source rawan and han at the university of arizona libraries have been collaborating with the afghanistan centre at kabul university (acku), the de facto national library of afghanistan. the purpose of the 13-year-long collaboration is to preserve and provide open access to afghanistan’s unique materials from the acku’s physical collections. initially funded by a grant of $350,000 from the national endowment for the humanities (neh) for the period of 2008 to 2012, the project digitized 200,000 pages of materials from the modern period. the project continues to receive support from the university of arizona and the acku. the acku’s permanent collection is the most extensive in the region covering a time of war and social upheaval in the country, with most of the documents in the principal languages of pashto, dari (persian), and english with a variety of formats such as monographs, series, reports, yearbooks, videos, and newspapers. in addition, rawan and han also pursued related afghani scholars’ collections including those of ludwig w. adamec and m. mobin shorish. a repository (www.afghandata.org) has been openly accessible containing these unique materials dating from the 1950s to the present. the repository has grown from the initial 200,000 pages to 2 million, and is the biggest digital repository in the world covering afghanistan and its region with more than 200,000 active users viewing 400,000 pages per year. the wealth of the materials in terms of content, formats, and sources of information makes them undoubtedly the ultimate source of information for the studies of afghanistan and its region. from a data scientist’s point of view, the repository is a treasure trove for big data and ml purposes because it consists of a diversity of content from many sources in a variety of formats and document layouts. selection the selected books, published in 1986, 2002, and 2006 respectively, vary in fonts, printing, and digitization quality. ms. rawan, a

recognition consists of the following stages: preprocessing, document layout analysis, page segmentation, classification, and postprocessing. in our research, we refer to segmentation as the process of partitioning a digital image into one or more information blocks. the segmentation app is used during the preprocessing and segmentation stages. sturgeon’s paper discussed major methods for preprocessing and character segmentation.17 multiple papers discussed various methods to do arabic or pashto text segmentation, including • horizontal projection18 • baseline 19 • template matching 20 • contour analysis 21 • zoning, 22 and • a combination of one or more above methods such as contour analysis and template matching.23 these methods have certain issues when dealing with letters with dots on the top or the bottom, and diacritics, specific to pashto scripts, as the pashto alphabet contains more letters and diacritics than its counterparts in arabic and persian. in addition, noise from original low-quality printing and digitization creates additional barriers. ullah et. al.24 briefly mentioned text area detection and segmentation with the detection and removal of diacritics. their segmentation goes from line segmentation using the horizontal projection, to word, and then to character level progressively. the letters (e.g., څ ,ټ, ښ) are sensitive to noise randomly appearing in page images. our method has proven to be successful in getting accurate character and line segments with the benefits of simplicity and program efficiency. details of discussion of the method are beyond the scope of this paper and shall be discussed in another paper. the author and a postdoctoral researcher created the code to identify pashto/persian text lines from page images, where the page images are from our digitization master files. our method takes a different approach from the above segmentation methods. algorithms and specific properties related to the characteristics of pashto letters have been implemented. we called it the “expanding textbox” method, which calculates the overlapping ratio of one textbox with the others and merges them based on a confidence level controlled by users. the confidence level of overlapping ratio is controlled by properties such as textbox, overlaptype, overlapthreshold, maxdiacriticssize, and minlineheight. to achieve segmentation, the app is also a specific image processing program that contains common preprocessing algorithms such as binarization.

libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 7 all commercial and open-source ocr systems give users few choices in page segmentation. we believe that the availability of flexible adjustments unique to the pashto/persian/arabic alphabets allows users to achieve accurate results based on analysis of our largest collections of pashto materials. our huge collections of printed materials spanning the period from the 1950s to the 2010s were published by governments, non-profit organizations, local companies, and individuals. these materials were printed in a diverse range of fonts and printing quality. the app has unique features to allow users to adjust several variables to ensure that they have accurate segmentation. segmentation parameters such as vertical expansion and horizontal expansion (see fig. 1) can be adjusted to expand the line vertically and/or horizontally. our experiments show that typically vertical expansion is set to −0.15 and horizontal expansion is set to 5 for most of the page images from our collections. however, both variables are subject to change if lines are not segmented correctly. figures 2 and 3 show a real-life example of the different values in the vertical expansion (set to 0.20) to get all of the correct lines. users can adjust these variables to achieve desired outputs if diacritics and lines are not recognized correctly. the app was programmed using matlab, which can run on matlab or run independently if packaged with matlab. the app can be exported to other platforms and run in batch mode if needed. the app has a simple gui (see fig. 1) providing a preview of expanded ligatures, expanded diacritics, lines of text, and binarized image windows. this allows users to adjust segmentation variables and verify results before outputting. figure 4 demonstrates an example of lines of text preview. when satisfied, users can output these lines as images (one image per line from a page image). these line images are ready for ocr or manual transcription. figure 1. expanded diacritics (highlighted in red) and the app gui. information technology and libraries march

accurate dataset, we have a language specialist who keyed in, verified, and double-checked the corresponding pashto texts. a ph.d. student from the school of middle eastern and north african studies (with persian language fluency) was hired to complete this task. initially, we tried to ocr these line images by using the open-source system tesseract 4.x with the hope that its output would speed up the key-in process. unfortunately, the majority of the ocr results from these line images was not usable. to ensure that the dataset has the gold-standard one-to-one mapping of a line image to a line text, the ph.d. student keyed in pashto texts line by line by viewing every individual line image. figure 5 shows a sample line image and its text. finally, ms. rawan and the author han reviewed these line images and their corresponding texts. the dataset is organized in a hierarchical structure consisting of directories, where each directory contains line subdirectories which hold line images and its texts. the dataset is openly available at github (https://github.com/yhan818/pashto-dataset). figure 5. sample line image and corresponding text. discussion the nature of the scripts and the writing systems may require different algorithms and considerations when we deal with ocr technology, including preparing datasets, segmentation, and performing ocr in computer vision. in our research in specific languages, we have tested this app with documents in pashto, persian/dari and arabic with successful results. our textbox extension method should work for any language using the arabic writing system beyond these above scripts. during our research, we are clearly aware of the following limitations of the ocr technology, techniques and systems: 1) lack of high accuracy in segmentation: a) while it is true that ocr on the character/word accuracy of the latin scripts can exceed 95% accuracy, one shall not believe that the accuracy of a document after ocr will be at the same level. depending on the nature of a document, segmentation accuracy varies among documents. ocring documents in simple layout (e.g., a monograph without columns and tables) generally reaches high accuracy, while ocring documents with complex layouts (e.g., newspapers and scientific articles) generates poor results. b) we have tested multiple popular commercial and open-source ocr systems specifically in the area of segmentation. on several samples, every ocr system failed completely. in other words, the text output of every ocr system is nonsense. in some cases, only abbyy recognized columns correctly; the remaining systems unexpectedly transposed https://github.com/yhan818/pashto-dataset information technology and libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 11 text columns, which means potential indexing and searching errors, although the character and word accuracy reached 95% accuracy. c) we argue that segmentation accuracy shall be added as one of the most important evaluation criteria. 2) to date almost all ocr technology and systems are limited to text only: a) missing information in other formats: we agree that plain text in the writing systems is the most commonly used and a very important communication method. however, almost all materials contain information in other formats (e.g., illustrations, figures, tables, and formulas) that may be very difficult to describe in text. an individual page from a monograph, journal article, or newspaper may contain information in other formats beyond text. such information can be a table, mathematical formula, figure, picture, or drawing. one company, mathpix, recently started to provide ocr on simple tables and mathematical formulas for a fee. b) missing semantic information: in addition, current ocr simply outputs plain text, ignoring existing semantic information (e.g., bold highlighted text and section/subsection headings in different fonts and sizes). ocr refers to character recognition, which limits its own scope in theory. in current practices, semantic information is totally ignored by every ocr system. scant research has been carried out for them too. conclusion and future work so far, we have created a pashto dataset containing 300 line images and their corresponding text from three pashto monographs published in 1986, 2002, and 2006, respectively. the dataset is openly available as a gold-standard pashto dataset from real books. when future funding is received, we will add more data to this dataset. the segmentation app produces accurate line images from page images for pashto and persian content. it will work for other languages using the arabic writing system. potential users of our prototype software will find it is relatively easy to modify with little knowledge of the underlying technology in other programming languages such as java. in addition, researchers who understand linear algebra in which matlab is used can modify the code for their needs. we are also using this dataset to train and evaluate our current ocr algorithms with rnn and other ml models. an initial report of our research and results can be found at arxiv.org.25 the authors will report and update future research results and available datasets via conferences and formal publications. the authors

standardized set of letters and symbols. the most popular are the latin alphabet (a–z) and the arabic alphabet. • classification: in machine learning, classification is to assign a sample to one or more classes by supervised learning from examples. • dataset: a set of data. a dataset can be in a variety of forms or formats (e.g., text, images, audio, videos, 3d objects, gps data, machine learning data), from one table, to a collection of images of handwritten digits (e.g., mnist database), to a collection of metadata of a digital repository (e.g., arxiv dataset). • document layout analysis: in the ocr technology, document layout analysis is the process of identifying the layout and categorizing the information blocks in a digital image of a document. the goal is to segmentalize one information block from the other and arrange these information blocks in the correct reading order. • language: a structured system of communication; the system of linguistic signs or symbols considered in the abstract (as opposed to speech). • left to right (ltr) first and top to bottom (ttb) writing direction: writing a horizontal line starting from the top left of a page, continuing to the right, and returning to the next line all the way from top to bottom. the latin writing system uses this writing direction. the current chinese writing system uses this order as well. • logogram: a written character that represents a word or phrase. the most popular are chinese (simplified and traditional) characters, kanji (japanese), and hanja (korean). • optical character recognition (ocr): conversion of an image consisting of text (printed or handwritten) into digital text. • page segmentation: segmentation process for a scanned page in a digital image file format. • right to left (rtl) first and top to bottom (ttb) writing direction: writing a horizontal line starting from the top right of a page, continuing to the left, returning to the next line and all the way from top to bottom. the arabic writing systems such as arabic, persian, and pashto use this order. • script: “[a] collection of letters and other written signs used to represent textual information in one or more writing systems.”26 • segmentation: segmentation is the process of partitioning a digital image of a document into multiple segments where each segment consists of a set of pixels. it aims at separating the digital image into one or more information blocks, where each information block contains logical information separated from the other information block. these information blocks shall be arranged in the correct reading order. (see document layout analysis) • textbox: in an ocr system, a textbox is a box with (x,y) (identified in the computer source code) that contains one or more characters. • top to bottom (ttb) first and left to right (ltr) writing direction: writing a vertical line starting from the top left of a page, continuing to the bottom, and returning to the next line all the way from left to right. this method is rarely used by any writing system. • top to bottom (ttb) first and right to left (rtl) writing direction: writing a vertical line starting from the top right of a page, continuing to the bottom, and returning to the next line all the way from right to left. this method was widely used in traditional chinese (before 1950s) and traditional japanese materials for thousands of years. it is still used in chinese calligraphy, and occasionally can be found in materials published in chinese. • writing system: a common communication method to allow people to exchange information through a medium such as paper. information technology and libraries march 2021 development of a gold-standard pashto dataset and a segmentation app | han and rychlik 13 endnotes 1 lu gan, email message to author, march 25, 2019. 2 donald sturgeon, “large-scale optical character recognition of pre-modern chinese texts,” international journal of buddhist thought and culture 28, no. 2 (2018): 11–44, https://dsturgeon.net/papers/large-scale-chinese-ocr.pdf. 3 donald sturgeon, “digitizing premodern text with the chinese text project,” journal of chinese history 4, no. 2 (2020): 486–98, https://doi:10.1017/jch.2020.19. 4 “glossary of unicode terms,” the unicode consortium, last updated may 20, 2020, http://www.unicode.org/glossary/. 5 the unicode standard version 13.0—core specification: chapter 17: indonesia and oceania (the unicode consortium: mountain view, ca, 2020), https://www.unicode.org/versions/unicode13.0.0/ch17.pdf#g26723. 6 britta-maria gruber and wolfgang kirsch, “writing machu on a western computer (an interim report),” saksaha: a journal of manchu studies, 3, (1998): https://doi.org/10.3998/saksaha.13401746.0003.008. 7 herbert penzl, a grammar of pashto: a descriptive study of the dialect of kandahar, afghanistan.

initiatives michael j. dulock and holley long information technology and libraries | december 2015 5 abstract this article describes a case study in which a small team from the digital initiatives group and metadata services department at the university of colorado boulder (cu-boulder) libraries conducted a pilot of the scrum project management framework. the pilot team organized digital initiatives work into short, fixed intervals called sprints—a key component of scrum. working for more than a year in the modified framework yielded significant improvements to digital collection work, including increased production of digital objects and surrogate records, accelerated publication of digital collections, and an increase in the number of concurrent projects. adoption of sprints has improved communication and cooperation between participants, reinforced teamwork, and enhanced their ability to adapt to shifting priorities. introduction libraries in recent years have freely adapted methodologies from other disciplines in an effort to improve library services. for example, librarians have • employed usability testing techniques to enhance users’ experience with digital libraries interfaces,1 improve the utility of library websites,2 and determine the efficacy of a visual search interface for a commercial library database;3 • adopted participatory design methods to identify information visualizations that could augment digital library services4 and determine user needs in new library buildings;5 and • utilized principles of continuous process improvement to enhance workflows for book acquisition and implementation of serial title changes in a technical services unit.6 librarians often come to the profession with disciplinary knowledge from an undergraduate degree unrelated to librarianship, so it should come as no surprise that they bring some of that disciplinary knowledge to their work. the interdisciplinary nature of librarianship also creates an environment that is amenable to adoption or adaptation of techniques from a variety of sources, not only those originating in library science. in this paper, the authors describe their experiences michael j. dulock (michael.dulock@colorado.edu) is assistant professor and metadata librarian, university of colorado boulder. holley long (longh@uncw.edu), previously assistant professor and systems librarian for digital initiatives at university of colorado, boulder, is digital initiatives librarian, randall library, university of north carolina wilmington.

framework to facilitate digital collection production. they begin by elucidating the fundamentals of scrum and then describes a pilot project using aspects of the methodology. they discuss the outcomes of the pilot and posit additional features of scrum that may be adopted in the future. fundamentals of scrum project management the scrum project management framework—one of several techniques under the rubric of agile project management—originated in software development, and has been applied in a variety of library contexts including the development of digital library platforms7 and library web applications.8 scrum’s salient characteristics include self-managing teams that organize their work into “short iterations of clearly defined deliverables” and focus on “communication over documentation.”9 the scrum primer: a lightweight guide to the theory and practice of scrum describes the roles, tools, and processes involved in this project management technique.10 scrum teams are cross-functional and consist of five to nine members who are cross-trained to perform multiple tasks. in addition to the team, two individuals serve specialized roles, scrum master and product owner. the scrum master is responsible for ensuring that scrum principles are followed and for removing any obstacles that hinder the team’s productivity. hence the scrum master is not a project manager, but a facilitator. the product owner’s role is to manage the product by identifying and prioritizing its features. this individual represents the stakeholders’ interests and is ultimately responsible for the product’s value. the team divides their work into short, fixed intervals called sprints that typically last two to four weeks and are never extended. at the beginning of each sprint, the team meets to select and commit to completing a set of deliverables. once these goals are set, they remain stable for the duration; course corrections can occur in later sprints. in software development, the scrum team aims to complete a unit of work that stands on its own and is fully functional, known as a potentially shippable increment. it is selected from an itemized list of product features called the product backlog. the backlog is established at the outset of development and consists of a comprehensive list of tasks that must occur to complete the product. a well-constructed backlog has four characteristics. first, it is prioritized with the features that will yield the highest return on investment at the top of the list. second, the backlog is appropriately detailed, so that the tasks at the top of the list are well-defined whereas those at the bottom may be more vaguely demarcated. third, each task receives an estimation for the amount of effort required to complete it, which helps the team to project a timeline for the product. finally, the backlog evolves in response to new developments. individual tasks may be added, deleted, divided, or reprioritized over the life of the project. during the course of a sprint, team members meet to plan the sprint, check-in on a daily basis, and then debrief at the conclusion of the sprint. they begin with a two-part planning meeting in which the product owner reviews the highest priority tasks with the team. in the second half of the meeting, the team and the scrum master determine how many of the tasks can be accomplished in information technologies and libraries |december 2015 7 the given timeframe, thus defining the goals for the sprint. this meeting generally lasts no longer than four hours for a two-week sprint. every day, the team holds a brief meeting to get organized and stay on track. during these “daily scrums,” each team member shares three pieces of information: what has been accomplished since the previous meeting, what will be accomplished before the next meeting, and what, if any, obstacles are impeding the work. these fifteen-minute meetings provide the team with a valuable opportunity to communicate and coordinate their efforts. sprints conclude with two meetings, a review and retrospective. during the review, the team inspects the deliverables that were produced during that sprint. the retrospective provides an opportunity to discuss the process, what is working well, and what needs to be adjusted. figure 1. typical meeting schedule for a two-week sprint evidence in the literature suggests that scrum improves both outcomes and process. one metaanalysis of 274 programming case studies found that implementing scrum led to improved productivity as well as greater customer satisfaction, product quality, team motivation, and cost reduction.11 proponents of this project management technique find that it leads to a more flexible and efficient process. scrum’s brief iterative work cycles and evolving product backlog promote adaptability so the team can address the inevitable changes that occur over the life of a project. by contrast, traditional project management techniques have been criticized for requiring too much time upfront on planning and being too rigid to respond to changes in later stages of the project.12 scrum also promotes communication over documentation,13 resulting in less administrative overhead as well as increased accountability and trust between team members. scrum pilot at university of colorado boulder libraries the university of colorado boulder (cu-boulder) libraries digital initiatives team was interested in adopting scrum because of its incremental approach to completing large projects, its focus on communication, and its flexibility. these attributes meshed well with the group’s goals to publish larger collections more quickly and to more effectively multitask the production of multiple high digital collections are a sprint, not a marathon | dulock and long | doi: 10.6017/ital.v34i4.5869 8 priority collections. the group’s staffing model and approach to collection building prior to the scrum pilot is described here to provide some context for this choice of project management tool. digital collection proposals are vetted by a working group composed of ten members, the digital library management group (dlmg), to ensure that major considerations such as copyright status are fully investigated before undertaking the collection. approved proposals are prioritized by the appropriate collection manager as high, medium, or low and then placed in a queue for scanning and metadata provisioning. a core group of individuals generally works on all digital collections, including the metadata librarian, the digital initiatives librarian, and one or both of the digitization lab managers. additionally, the team frequently includes the subject specialist who nominated the collection for digitization, staff catalogers, and other library staff members whose expertise is required. at any given time, the queue may contain as many as fifteen collections, and the core team works on several of them concurrently to address the separate needs of participating departments. while this approach allows the teams to distribute resources more equitably across departments, progress on individual collections can be slower than if they are addressed one at a time. prior to implementing aspects of scrum, the team also completed the scanning and metadata records for every object in the collection before it was published. as a result, publication of larger collections trailed behind smaller collections. the details of digital collection production vary depending of the nature of the project, but the process usually follows the same broad outline. unless the entire collection will be digitized, the collection manager chooses a selection of materials on the basis of criteria such as research value, rarity, curatorial considerations, copyright status, physical condition, feasibility for scanning, and availability of metadata. photographs and paper-based materials are then evaluated by the preservation department to ensure that they are in suitable condition for scanning. likewise, the media lab manager evaluates audio and video media for condition issues such as sticky shed syndrome, which will affect digitization.14 depending on format, the material is then digitized by the digitization lab manager or the media lab manager and their student assistants according to locally established workflows that conform to nationally recognized best practices. once digitized, student assistants apply post-processing procedures as appropriate and required, such as running ocr (optical character recognition) software to convert images to text or equalizing levels on an audio file. the lab managers then check the files for quality assurance and move the files to the appropriate location on the server. the metadata librarian creates a metadata template appropriate to the material being digitized by using industry standards such as visual resources association core (vra core), metadata object description schema (mods), pbcore, and dublin core (dc). metadata creation methods depend on the existence of legacy metadata for the analog materials and in what format legacy metadata is contained. the metadata librarian, along with his staff and/or student assistants, adapts legacy metadata into a format that can be ingested by the digital library software or creates records directly in the software when there is no legacy metadata. metadata is formatted or created in accordance with existing input standards such as cataloging cultural objects (cco) and resource description and access (rda), and it is enhanced information technologies and libraries |december 2015 9 as much as possible using controlled vocabularies such as the art and architectural thesaurus (aat) and library of congress subject headings. the metadata librarian performs quality assurance on the metadata records during creation and before the collection is published. in the final stages, the collection is created in the digital library software, at which time search and display options are established: thumbnail labels, default collection sorting, faceted browsing fields, etc. then the files and metadata are uploaded and published online. the highlight of the cu-boulder digital library is the twenty-seven collections drawn from local holdings in archives, special collections department, music library, and earth sciences and map library, among others. the library also contains purchased content and “luna commons” collections created by institutions that use the same digital library platform, for a total of more than 185,000 images, texts, maps, audio recordings, and videos. the following four collections were created during the scrum pilot and illustrate the types of materials available in the cuboulder digital library: the colorado coal project consists of video and audio interviews, transcripts, and slides collected between 1974 and 1979 by the university of colorado coal project. the project was funded by the colorado humanities program and the national endowment for the humanities to create an ethnographic record of the history of coal mining in the western united states from immigration and daily life in the coal camps to labor conditions and strikes, including ludlow (1913–14) and columbine (1927). the mining maps collection provides access to scanned maps of various mines, lodes, and claims in colorado from the late 1800s to the early 1900s. these maps come from a variety of creators, including private publishers and us government agencies. digital collections are a sprint, not a marathon | dulock and long | doi: 10.6017/ital.v34i4.5869 10 the vasulka media archive showcases the work of pioneering video artists steina and woody vasulka and contains some of their cutting-edge studies in video that experiment with form, content, and presentation. steina, an icelander, educated in music at the prague conservatory of music, and woody, a graduate of prague's film academy, arrived in new york city just in time for the new media explosion. they brought with them their experience of the european media awakening, which helped them blend seamlessly into the youth media revolution of the late sixties and early seventies in the united states. the 3d natural history collection comprises one hundred archaeology and paleontology specimens from the rocky mountain and southwest regions, including baskets, moccasins, animal figurines, game pieces, jewelry, tools, and other everyday objects from the freemont, clovis, and ancestral puebloan cultures as well as a selection of vertebrate, invertebrate, and track paleontology specimens from the mesozoic through the cenozoic eras (250 ma to the present). the diffusion of effort across multiple collections and a slower publication rate for larger collections offered opportunities for improvement. after attending a conference session on scrum project management for web development projects, one of the team members recognized scrum’s potential to improve production processes since the technique divides large projects into manageable subtasks that can be accomplished in regular, short intervals.15 this approach would allow the team to switch between different high priority collections at regularly defined intervals to facilitate steady progress on competing priorities. working in sprints would also make it easier to publish smaller portions of a large collection at regular intervals. thus scrum held the potential to increase the production rate for larger collections and make the team’s progress more transparent to users and colleagues. in april 2013, a small team of cu-boulder librarians and staff initiated a pilot to assess the effect on processes and outcomes for digital collection production. rather than involving individuals from all affected units, regardless of their level of engagement in a particular project, the scrum pilot was limited to the three individuals who were involved in most, if not all, of the projects information technologies and libraries |december 2015 11 undertaken: the digital initiatives librarian, metadata librarian, and digitization lab manager.16 by including these three individuals, the major functions of metadata provision, digitization, and publication were covered in the trial with no disruption to the existing workflows or organizational structures. selecting this group also ensured that scrum would be tested in a broad range of scenarios and on collections from several different departments. to begin, the team met to review the scrum project management framework and considered how best to pilot the technique. taking a pragmatic approach, they only adopted those aspects of scrum that were deemed most likely to result in improved outcomes. if the pilot were successful, other aspects of scrum could be incrementally incorporated later. the group discussed how scrum roles, processes, and tools could be adapted to digital collection workflows and determined that sprints would likely have the highest return on investment. they also chose to adapt and hybridize certain aspects of the planning meeting and daily scrum to achieve goals that were not being met by other existing meetings. sprint planning and end meetings were combined so that all three participants knew what each had completed and what was targeted for the next sprint. select activities of sprint planning and end meetings were already a part of the monthly dlmg meetings, making additional sprint meetings redundant. daily scrum meetings were excluded as the team felt that daily meetings would not produce enough benefit to justify the costs. in addition, two of the three participants have numerous responsibilities that lie outside of projects subject to the scrum pilot, so each person does not necessarily perform scrum-related work every day. however, the short meeting time was adopted into the planning/end meeting, as were elements of the three core questions of the daily scrum meeting, with some modifications. the questions addressed in the biweekly meetings are: what have you done since the last meeting? what are you planning for the next meeting? what impediments, if any, did you encounter during the sprint? the latter question was sometimes addressed mid-sprint through emails, phone calls, or one-off meetings that include a larger or different group of stakeholders. the team adopted the two-week duration typical of scrum sprints for the pilot. this has proven to be a good medium-term timeframe. it was short enough that the team could adjust priorities quickly, but long enough to complete significant work. the team chose to combine the sprint planning and sprint review meetings into a single meeting. part of the motivation for a trial of the scrum technique was to minimize additional time away from projects while maximizing information transfer during the meetings. a single biweekly planning/review meeting was determined to be sufficient to report accomplishments and set goals yet substantial and free of irrelevant content without being overly burdensome as “yet another meeting.” at each sprint meeting, each participant reported on results from the previous sprint. work that was completed allowed the next phase of a project to proceed. based on the results of the last sprint, each team member set measurable goals that could be realistically met in the next twoweek sprint. there has been a concerted effort to keep the meetings short, limited to about twenty digital collections are a sprint, not a marathon | dulock and long | doi: 10.6017/ital.v34i4.5869 12 to twenty-five minutes. to enforce this habit, the sprint meetings were scheduled to begin twenty minutes before other regularly scheduled meetings for most or all of the participants. this helped keep participants on-topic and reinforced the transfer-of-information aspect of the meetings, with minimal leeway for extraneous topics. reflection the modified scrum methodology described above has been in place for more than a year. there have been several positive outcomes resulting from this practice. beginning with the most practical, production has become more regular than it was before scrum was implemented. the nature of digital initiatives in this environment dictates that many projects are in progress at once, in various stages of completion. the production work, such as digitizing media or creating metadata records, has become more consistent and regular. instead of production peaks and valleys, there is more of a straight line as portions of projects are finished and others come online. this in turn has resulted in faster publication of collections. in 2013, the team published six new collections, twice as many as the previous year. the ability to put all hands on deck for a project for a two-week period can increase productivity. since sprints allow for short, concentrated bursts of work on a single project, smaller projects can be completed in a few sprints and larger projects can be divided into “potentially shippable units” and thus published incrementally. another benefit of scrum is that the variability of the two-week sprint cycle allows the team to work on more collections concurrently. for example, during a given sprint, scanning is underway for one collection, a metadata template is being constructed for another, the analog material in a third is being examined for pre-scanning preservation assessment, and a fourth collection is being published. while this type of multitasking occurred before the team piloted sprints, the scrum project management framework lends more structure and coordination to the various team members’ efforts. collection building activities can be broken down into subtasks that are accomplished in nonconsecutive sprints without undercutting the team’s concerted efforts. as a result, the team can juggle competing priorities much more effectively. the team is working with multiple stakeholders at any given time, each of whom may have several projects planned or in progress. as focus shifts among stakeholders and their respective projects, the scrum team is able to adjust quickly to align with those priorities, even if only for a single sprint. this also makes it easier to respond to emerging requests or address small, focused projects on the basis of events such as exhibits or course assignments. additional benefits of the scrum methodology pertain to communication and work style among the three scrum participants. the frequent, short meetings are densely packed and highly focused. each person has only a few minutes to describe what has been accomplished, explain problems encountered, troubleshoot solutions, and share plans for the next sprint. the return on the time investment of twenty minutes every two weeks is significant—there is no time to waste on issues that do not pertain directly to the projects underway, just completed, or about to start. a further result is that the group’s sense of itself as a team is enhanced. as stated above, the three scrum information technologies and libraries |december 2015 13 participants do not all work in the same administrative unit within the library. though they shared frequent communication by email as projects progressed, regular sprint meetings have fostered a closer sense of team. the participants know from sprint to sprint what the others are doing; they can assist one another with problems face-to-face and coordinate with one another so that work segments progress toward production in a logical sequence. with more than a year of experience with scrum, the pilot team has determined that several aspects of the methodology have worked well in our environment. in general, the sprint pattern fits well with existing operating modes. the monthly dlmg meeting, which includes a large and diverse group, provides an opportunity to discuss priorities, review project proposals, establish standards, and make strategic decisions. the bi-weekly sprint meetings dovetail nicely, with one meeting taking place at a midpoint between dlmg meetings, and one just prior to dlmg meetings. this allows the three scrum participants to focus on strategic items during the dlmg meeting but keep a close eye on operational items in between. the scrum methodology has also accommodated the competing priorities that the three participants must balance on an ongoing basis. there is considerable variation between participants in terms of roles and responsibilities, but the division of work into sprints has given the team greater opportunity to fit production work in with other responsibilities, such as supervision and training; scholarly research and writing; service performed for disciplinary organizations; infrastructure building; and planning, research, and design work for future projects. the two-week sprint duration is a productive time interval during which the team can set and reach incremental goals, whether that is starting and finishing a small project on short notice, making a big push on a large-scale project, or continuing gradual progress on a large, deliberatelypaced initiative. the brief meetings ensure that participants focus on the previous sprint and the upcoming sprint. there is usually just enough time to discuss accomplishments, goals, and obstacles, with some time left to troubleshoot as necessary. the meeting schedule and structure allows each individual to set his or her own goals so that he or she can make maximum progress during the sprint. this in turn feeds into accountability. there is always an external check on one’s progress—the next meeting comes up in two weeks, creating an effective deadline (which also sometimes corresponds to a project deadline). it becomes easier to stay on task and keep goals in sight with the sprint report looming in a matter of days. at the same time, scrum helps to define each person’s role and clarifies how roles align with each other. some tasks are completely independent, while others must be done in sequence and depend on another’s work. the sprint schedule allows large, complex projects to be divided into manageable pieces so that each sprint can result in a sense of accomplishment, even if it may require many sprint cycles to actually complete a project. this is especially true for large digital initiatives. for instance, completing the entire project may take a year, but subsets of a collection may be published in phases at more frequent intervals in the meantime. digital collections are a sprint, not a marathon | dulock and long | doi: 10.6017/ital.v34i4.5869 14 summary of benefits ● enhanced ability to manage multiple concurrent projects ● published large collections incrementally, increasing responsiveness to users and other stakeholders ● improved team building ● increased communication and accountability among team members future considerations based on these outcomes, the team can safely say that it met its objectives for the test pilot. one of the reasons that it was feasible to try this when the participants were already highly committed is that the pilot used a small portion of the scrum methodology and was not too rigid in its approach. the team felt that a hybrid of the scrum planning and scrum review meeting held twice a month would provide the benefits without overburdening schedules with additional meetings. there were also plans to have a virtual email check-in every other week to loosely achieve the goals of the daily scrum meeting, that is, to improve communication and accountability. the email check-in fell by the wayside; the team found it wasn’t necessary because there were already adequate opportunities to check-in with each other over the course of a two-week sprint. the team has found the sprints and modified scrum meetings to be highly useful and relatively easy to incorporate into their workflows. the next phase of the pilot will implement product backlogs and burn down charts, diagrams showing how much work remains for the team in a single sprint, with the goal of tracking collections’ progress at the item level through each step of the planning, selection, preservation assessment, digitization, metadata provisioning, and publication workflows. figure 2. hypothetical backlog for the first sprint of a digital collection17 information technologies and libraries |december 2015 15 scrum backlogs are arranged on the basis of a task’s perceived benefit for customers. to adapt backlogs for digital collection production work, the backlog task list’s order will instead be based in part on the workflow sequence. for example, pieces from the physical collection must be selected before preservation staff can assess them. additionally, the backlog items will be sequenced according to the materials’ research value or complexity. for instance, the digitization of a folder of significant correspondence from an archival collection would be assigned a higher priority in the backlog than the digitization of newspaper clippings of minor importance from the same collection. or, materials that are easy to scan would be listed in the backlog ahead of fragile or complex items that require more time to complete. this will allow the team to publish the most valuable items from the collection more quickly. according to scrum best practices, backlogs are also appropriately detailed. in the context of digital collection production work, collections’ backlogs would begin with a standard template of high-level activities: materials’ selection, copyright analysis, preservation assessment, digitization, metadata creation, and publication. as the team progresses through backlog items, they will become increasingly detailed. backlogs also evolve. scrum’s ability to respond to change has been one of its strongest assets in this environment and therefore the backlog’s ability to evolve will make it a valuable addition to the team’s process. for example, materials that a collection manager uncovers and adds to the project late in the process can be easily incorporated into the backlog or materials in the collection that are needed to support an upcoming instruction session can be moved up in the backlog for the next sprint. in this way, the backlog will support the team’s goal to nimbly respond to shifting priorities and emerging opportunities. figure 3. hypothetical burn down chart18 digital collections are a sprint, not a marathon | dulock and long | doi: 10.6017/ital.v34i4.5869 16 the final relevant feature of a backlog, the “effort estimates,” taken in conjunction with the burn down chart will help the team develop better metrics for estimating the time and resources required to complete a collection. when items are added to the backlog, team members estimate the amount of effort needed to complete it. the burn down chart illustrates how much work remains and, in general practice, is updated on a daily basis. given that the team has truncated the scrum meeting schedule, this may occur on a weekly basis, but will nonetheless benefit the team in several ways. initially, it will keep the team on track and provide valuable and detailed information for stakeholders on the collections’ progress. as the team accrues old burn down charts from completed collections, they can use the data to hone their ability to estimate the amount of time and resources needed to complete a given project. conclusion through the pilot conducted for digital initiatives at cu-boulder libraries, application of aspects of the scrum project management framework has demonstrated significant benefits with no discernable downside. adoption of sprint planning and end meetings resulted in several positive outcomes for the participants. digital collection production has become more regular; work can be underway on more collections simultaneously; and collections are, on average, published more quickly. in addition, communication and cooperation among the sprint pilot participants have increased and strengthened the sense of teamwork among them. the sprint schedule has blended well with existing digital initiatives meetings and workflows, and has enhanced the team’s ability to handle ever-shifting priorities. additional aspects of scrum, such as product backlogs and burn down charts, will be incorporated into the participants’ workflows to allow them to better track the work done at the item level, provide more detailed information for stakeholders during the course of a project, and predict how much time and effort will be required for future projects. the positive results of this pilot demonstrate the benefits to be gained by looking outside standard library practice and adopting techniques developed in another discipline. given the range of activities performed in libraries, the possibilities to improve workflows and increase efficiency are limitless as long as those doing the work keep an open mind and a sharp eye out for methodologies that could ultimately benefit their work, and in turn, their users. references 1. sueli mara ferreira and denise nunes pithan, “usability of digital libraries,” oclc systems & services: international digital library perspectives 21, no. 4 (2005): 316, doi:

study on providing search suggestions david ward, jim hahn, and kirsten feist information technology and libraries | december 2012 6 abstract as the library website and its online searching tools become the primary “branch” many users visit for their research, methods for providing automated, context-sensitive research assistance need to be developed to guide unmediated searching toward the most relevant results. this study examines one such method, the use of autocompletion in search interfaces, by conducting usability tests on its use in typical academic research scenarios. the study reports notable findings on user preference for autocomplete features and suggests best practices for their implementation. introduction autocompletion, a searching feature that offers suggestions for search terms as a user types text in a search box (see figure 1), has become ubiquitous on both larger search engines as well as smaller, individual sites. debuting as the “google suggest” feature in 20041, autocomplete has made inroads into the library realm through inclusion in vendor search interfaces, including the most recent proquest interface and in ebsco products. as this feature expands its presence in the library realm, it is important to understand how patrons include it in their workflow and the implications for library site design as well as for reference, instruction, and other library services. an analysis of search logs from our library federated searching tool reveals both common errors in how search queries are entered, as well as patterns in the use of library search tools. for example, spelling suggestions are offered for more than 29 percent of all searches, and more than half (51 percent) of all searches appear to be for known items.2 additionally, punctuation such as commas and a variety of correct and incorrect uses of boolean operators are prevalent. these patterns suggest that providing some form of guidance in keyword selection at the point of searchterm entry could improve the accuracy of composing searches and subsequently the relevance of search results. this study investigates student use of an autocompletion implementation on the initial search entry box for a library’s primary federated searching feature. through usability studies, the authors analyzed how and when students use autocompletion as part of typical library research, asked the students to assess the value and role of autocompletion in the research process, and noted any drawbacks of implementing the feature. additionally, the study sought to analyze how

autocomplete implementation implementing autocompletion on the front end of a search affected providing search suggestions on the back end (search result pages). literature review autocomplete as a plug-in has become ubiquitous on site searches large and small. research on autocomplete includes a variety of technical terms that refer to systems using this architecture. examples include real time query expansion (rtqe), interactive query expansion, search-asyou-type (sayt), query completion, type-ahead search, auto-suggest, and suggestive searching/search suggestions. the principal research concerns for autocomplete include issues related to both back-end architecture and assessments of user satisfaction and systems for specific implementations. nandi and jagadish present a detailed system architecture model for their implementation of autocomplete, which highlights many of the concerns and desirable features of constructing an index that the autocomplete will query against.3 they note in particular that the quality of suggestions presented to the user must be high to compensate for the user interface distraction of having suggestions appear as a user types. this concern is echoed by hanmin et al. in their analysis of how the results offered by their autocomplete implementation met user expectations.4 their findings emphasize configuring systems to display only keywords that bring about successful searches, noting “precision [of suggested terms] is closely related with satisfaction.” an additional analysis of their implementation also noted that suggesting search facets (or “entity types”) is a way to enhance autocomplete implementations and aid users in selecting suitable keywords for their search.5 wu also suggests using facets to help group suggestions by type, which improves comprehension of a list of possible keyword combinations.6 in defining important design characteristics for autocomplete as a research tool | ward, hahn, and feist 8 autocomplete implementations, wu advocates building in a tolerance for misplaced keywords as a critical component. chaudhuri and kaushik examine possible algorithms to use in building this type of tolerance into search systems. misplaced keywords include typing terms in the wrong field (e.g., an author name in a title field), as well as spelling and word order errors.7 systems that are tolerant in this manner “should enumerate all the possible interpretations and then sort them according to their possibilities,” a specification wu refers to as “interpret-as-you-type.”8 additionally, both wu and nandi and jagadish specify fast response time (or synchronization speed) as a key usability feature in autocomplete interfaces, with nandi and jagadish indicating 100ms as a maximum.9,10 speed also is a concern in mobile applications, which is part of the reason paek et al. recommend autocomplete as part of mobile search interfaces, in which reducing keystrokes is a key usability feature.11 on the usability end, white and marchionini12 assess best practices for implementation of searchterm-suggestion systems and users’ perceptions of the quality of suggestions and search results retrieved. they find that offering keyword suggestions before the first set of results has been displayed generated more use of the suggestions than displaying them as part of a results page, even though the same terms were displayed in both cases. providing suggestions at this initial stage also led to better-quality initial queries, particularly in cases where users may have little knowledge of the topic for which they are searching. the researchers also warn that, while presenting “query expansion terms before searchers have seen any search results has the potential to speed up their searching . . . it can also lead them down incorrect search paths.”13 method usability study we conducted two rounds of usability testing on a version of university of illinois at urbanachampaign’s undergraduate library website that contained a search box for the library’s federated/broadcast search tool with autocomplete built in. the testing followed nielsen’s guidelines, using a minimum of five students for each round, with iterative changes to the interface made between rounds based on feedback from the first group.14 we conducted the initial round in summer 2011 with five library undergraduate student workers. the second round was conducted in september 2011 and included eight current undergraduate students with no affiliation to the library. by design, this method does not allow us to state definitive trends for all autocomplete implementations. it is not a statistically significant method by quantitative standards—rather, it gives us a rich set of qualitative data about the particular implementation (easy search) and specific interface (undergrad library homepage) being studied. the study’s questions were approved by the campus institutional review board (irb), and each participant signed an irb waiver before participating. students for the september round were recruited via advertisements on the website and flyers in the library. gift certificates to a local coffee shop provided the incentive for the study. information technology and libraries | december 2012 9 the procedure for each interview focused on two steps (see appendix). first, each participant was asked to use the search tool to perform a series of common research tasks, including three queries for known item searches (locating a specific book, journal, and movie), and two searches that asked the student to recall and describe a current or previous semester’s subject-based search, then use the search interface to find materials on that topic. participants were asked to follow a speak-aloud protocol, dictating the decision-making process they went through as they conducted their search, including noting why they made each choice that they made along the way. researchers observed and took notes, including transcribing user comments and noting mouse movements, clicks, and other choices made during the searches. because part of the hypothesis of the study was that the autocomplete feature would be used as an aid for spelling search queries correctly, titles with possibly challenging spelling were chosen for the known item searches. participants were not told about or instructed in the use of autocomplete; rather, it was left to each of them to discover it and individually decide whether to use it during each of the searches they conducted as a part of the study. in the second part of the interview, researchers asked students questions about their use (or lack thereof) of the autocomplete feature during the initial set of task-based questions. this set of questions focused on identifying when students felt the autocomplete feature was helpful as part of the search process, why they used it when they did, and why they did not use it in other cases. students also were asked more general questions about ways to improve the implementation of the feature. in the second round of testing (with students from the general campus populace), an additional set of questions was asked to gather student demographic information and to have the participants assess the quality of the choices the autocomplete feature presented them with. these questions were based in part on the work of white and marchionini, who had study participants conduct a similar quality analysis.15 autocomplete implementation the autocomplete feature was javascript and based on the jquery autocomplete plugin (http://code.google.com/p/jquery-autocomplete/). autocomplete plugins generally pull results either from a set of previous searches on a site or from a set of known products and pages within a site. for the study, the initial dataset used was a list of thousands of previous searches using the library’s easy search federated search tool. however, this data proved to be extremely messy and slow to search. in particular, a high number of problematic searches were in the data, including entire citations pasted in, misspelled words, and long natural-language strings. constructing an algorithm to clean up and make sense of these difficult queries would have required too much time and overhead, so we investigated other sources. researchers looked at autocomplete apis for both bing (http://api.bing.com/osjson.aspx?query=test) and google (the suggest toolbar api: http://google.com/complete/search?output=toolbar&q=test). both worked well and produced autocomplete as a research tool | ward, hahn, and feist 10 similar relevant results for the test searches. significantly, the search algorithms behind each of these apis were able to process the search query into far more meaningful and relevant results than what was achieved through the test implementation using local data. these algorithms also included correcting misspelled words entered by users by presenting correctly spelled results from the dropdown list. we ultimately chose the google api on the basis of its xml output. findings the study’s findings were consistent across both rounds of usability testing. notable themes include using autocomplete to correct spelling on known-item searches (specific titles, authors, etc.), to build student confidence with an unfamiliar topic, to speed up the search process, to focus broad searches, and to augment search-term vocabulary. the study also details important student perceptions about autocomplete that can guide the implementation process in both library systems and instructional scenarios. these student perceptions include themes of autocomplete’s popularity, desire for local resource suggestions, various cosmetic page changes, and user perception of the value of autocomplete to their peers. spelling “it definitely helps with spelling,” said one student, responding to a prompt of how they would explain the autocomplete feature to friends. correcting search-term spelling is a key way in which students chose to make use of the autocomplete feature. for known-item searches, all eight students in the second round of testing selected suggestions from auto-complete at least two times out of the three searches conducted. of those eight students, four (50 percent) used auto-complete every time (three out of three opportunities), and four (50 percent) used it 67 percent of the time (two out of three opportunities). we found that of this latter group who only selected auto-complete suggestions two out of the three opportunities presented, three of them did in fact refer to the dropdown selections when typing their inquiries, but did not actively select these suggestions from the dropdown all three times. in choosing to use autocomplete for spelling correction, one student noted that autocomplete was helpful “if you have an idea of a word but not how it’s spelled.” it is interesting to note, with regard to clicking on the correct spellings, that students do not always realize they are choosing a different spelling than what they had started typing. an example is the search for journal of chromatography, which some students started spelling as “journal of chormo,” then picked the correct spelling (starting “chroma”) from the list, without apparently realizing it was different. this is an important theme: if a student does not have an accurate spelling from which to begin, the search might fail, or the student will assume the library does not have any information on the chosen topic. this is particularly true in many current library catalog interfaces, which do not provide spelling suggestions on their search result pages. locating known items information technology and libraries | december 2012 11 another significant use of the autocomplete feature was in cases where students were looking for a specific item but had only a partial citation. in one case, a student used autocomplete to find a specific course text by typing in the general topic (e.g., “africa”) and then an author’s name that the course instructor had recommended. the google implementation did an excellent job of combining these pieces of information into a list of actual book titles from which to choose. this finding also echoes those of white and marchioni, who note that autocomplete “improved the quality of initial queries for both known item and exploratory tasks.”16 the study also found this to be an important finding because overall, students are looking for valid starting points in their research (see “confidence” below), and autocomplete was found to be one way to support finding instructor-approved items in the library. this echoes findings from project information literacy, which shows students typically turn to instructor-sanctioned materials first when beginning research.17 this use case typically arises when an instructor suggests an author or seminal text on a research topic to a student, often with an incomplete or inaccurate title. one participant also mentioned that they wanted the autocomplete feature to suggest primary or respected authors based on the topic they entered. confidence “[autocomplete is] an assurance that it [the research topic] is out there . . . you’re not the first person to look for it.”—student participant there were multiple themes related to the concept of user confidence discovered in the study. first, some participants noted that when they see the suggestions provided by autocomplete it verifies that what they are searching is “real”—validating their research idea and giving them the sense that others have been successful previously searching for their topic. when students were asked the source of the autocomplete suggestions, most thought that results were generated based on previous user searches. their response to this particular question highlighted the notion of “popularity ranking,” in that many were confident that the suggestions presented were a result of popular local queries. in addition, one participant thought that results generated were based on synonyms of the word they typed, while another believed that the results generated were included only if the text typed matched descriptions of materials or topics currently present in the library’s databases. some students did indicate the similarity of search results to google suggestions, but they did not make an exact connection between the two. this assumption that the terms are vetted seems to lend authority to the suggestions themselves and parallels the research of jung et al., who investigated satisfaction based on the connection between user expectations on selecting an autocomplete keyword and results.18 the benefit of autocomplete-provided suggestions in this context was noted even in cases when participants did not explicitly select items from the autocomplete list. students’ confidence in their own knowledge of a topic also factored into when they used autocomplete. participants reported that if they knew a topic well (particularly if the topic chosen was one that they had previously completed a paper on), it was faster to just type it in without autocomplete as a research tool | ward, hahn, and feist 12 choosing a suggestion from the autocomplete suggestion list. one participant also noted that common topics (e.g., “someone’s name and biography”) would also be cases in which they would not use the suggestions. after the first round of usability testing, a question was added to the post–test assessment asking students to rate their confidence as a researcher on a five-point scale. all participants in the second round rated themselves as a four or five out of five. while this confirms findings on student confidence from studies like project information literacy, this assessment question ultimately had no correlation to actual use of autocomplete suggestions during the subject-based research phase of the study. rather, confidence in the topic itself seemed to be the defining factor in use. speed the study also showed that speed is a factor in deciding when to use autocomplete functionality. specifically, autocomplete should be implemented in a way in which they are not perceived as slowing down the search process. this includes having results displayed in a way that is easily ignored if students want to type in an entire search phrase themselves, and having the presentation and selection of search suggestions done in a way that is easy to read and quick to be selected. autocomplete is perceived as a time-saver when clicking on an item will shorten the amount of typing students need to do. however, some students will ignore autocomplete altogether; they do this when they know what they want, and they feel that speed is compromised if they need to stop and look at the suggestions when they already know what they want to search. in the study, different participants would often cite speed as a reason for both selecting and not selecting an item for the same question, particularly with the known-item searches. this finding indicates that a successful implementation should include both a speedy response (as noted above in nandi and jagadish’s research on delivering suggestions within 100ms, paek et al.’s research on reducing keystrokes, and white and marchioni’s finding that providing suggested words was “a real time-saver”),19 as well as an interface which does not force users to select an item to proceed, or obscure the typing of a search query. focusing topics “it helps to complete a thought.” “[autocomplete is] extra brainstorming, but from the computer.”— participant responses the above quotes indicate the use of autocomplete as a tool for query formulation and search term identification, a function closely related to the association of college and research libraries (acrl) information literacy standard two, which includes competencies for selecting appropriate search keywords and controlled vocabulary related to a topic.20 this quote also parallels a similar finding from white and marchioni, 21 who had a user comment that autocomplete “offered words (paths) to go down that i might not have thought of on my own.” the use of autocomplete for scoping and refining a topic also parallels elements of the reference interview, specifically the open and closed questions typically asked to help a student define what information technology and libraries | december 2012 13 aspects of a topic they are interested in researching. this finding has many exciting implications for how elements and best practices from both classroom instruction and reference methodologies can be injected directly into search interfaces, to aid students who may not consult with a librarian directly during the course of their research. autocomplete was used at a lower rate, and in different ways, for subject searching compared to kown-item searching. three out of eight participants (38 percent) from the second round of testing did not use autocomplete at all for subject-based searching (zero of two opportunities). five out of eight participants (62 percent) used autocomplete on one of two search opportunities (50 percent). no participants used autocomplete on both of the search opportunities. the stage of research a student was in helped to indicate where and how autocomplete could be useful in topic formulation and search-term selection for subject searches. participants indicated that they would use autocomplete for narrowing ideas if they were at a later stage in a paper, when they knew more about what they wanted or needed specifics on their topic. however, early in a paper, some participants indicated they just wanted broad information and did not want to narrow possible results too early. this finding also supports previous research from project information literacy, which describes student desire to learn the “big-picture context” as a key function in the early part of the research process.22 at this topic-focusing stage, some participants told us that the search suggestions reminded them of topics that were discussed in class. further, the study showed that autocomplete suggests aspects of topics to student that they had not previously considered, and one participant indicated that she might change her topic if she saw something interesting from the list of suggestions, particularly something she had not thought of yet. interface implementation though students who opted to utilize the autocomplete feature were generally satisfied with the results generated, some students recommended increasing the number of autocomplete suggestions in the dropdown menu to increase the probability of finding their desired topic or known item or to potentially lead to other related topics to narrow their search. in addition, students recommended increasing the width of the autocomplete text box, as its present proportions are insufficient for displaying longer suggestions without text wrapping. some students also noted that increasing the height of the dropdown menu containing the autocomplete suggestions might help reduce the necessity to scroll through the results and may help to draw user attention to all results for those who elect not to use the scroll bar. beyond the suggested improvements for the functionality of the autocomplete feature, students also noted a few cosmetic changes they would like to see implemented. in particular, students would prefer to see larger text and a better use of fonts and font colors when using autocomplete. one student noted that if different fonts and colors were used in this feature, the results generated might stand out more and better attract users, or better draw users’ attention to the recommended search terms. autocomplete as a research tool | ward, hahn, and feist 14 perceived value to peers most students who participated in the study stated that they would recommend that their fellow classmates utilize the autocomplete feature for two primary purposes: known-item searches and locating alternative options for research topics. one student noted that she would recommend using this feature to search keywords “easily and efficiently,” while another student indicated that the feature helps to link to other related keywords. this finding also revealed that users were not intimidated by the feature and did not see it as a distraction from the search process, an initial researcher concern. conclusion and future directions implementation implications implementing autocomplete functionality that accounts for the observed research tendencies and preferences of users makes for a compelling search experience. participant selection of autocomplete suggestions varied between the types of searches studied. spelling correction was the one universally acknowledged use. for subject-based searching, confidence in the topic searched and the stage of research emerged as indicators of the likelihood of autocomplete suggestions being taken. the use and effectiveness of providing subject suggestions requires further study, however. students expect suggestions to produce usable results within a library’s collections, so the source of the suggestions should incorporate known, viable subject taxonomies to maximize benefits and not lead students down false search paths. there is an ongoing need to investigate possible search-term dictionaries outside of google, such as lists of library holdings, journal titles, article titles, and controlled vocabulary from key library databases. the “brainstorming” aspect of autocomplete for subject searching is an intriguing benefit that should be more fully explored and supported. in combination with these findings, participant’s positive responses to some of the assessment questions (including first impressions of autocomplete and willingness to recommend it to friends) indicate that autocomplete is a viable tool to incorporate site-wide into library search interfaces. instruction implications traditional academic library instruction tends to focus on thinking of all possible search terms, synonyms, and alternative phrasing before the onset of actual searching and engagement with research interfaces. this process is later refined in the classroom by examining controlled vocabulary within a set of search results. however, observations from this study (as well as researcher experience with users at the reference desk) indicate that students in real-world situations often skip this step and rely on a more trial-and-error method for choosing search terms, beginning with one concept or phrasing rather than creating a list of options that they try sequentially. the implication for classroom practice is that instruction on search-term formulation should include a review of autocomplete suggestions as well as practical methods for integrating these suggestions into the research process. this is particularly important as vendor databases information technology and libraries | december 2012 15 move toward making autocomplete a default feature. proper instruction in its use can help advance acrl information literacy goals and provide a practical, context-sensitive way to explain how a varied vocabulary is important for achieving relevant results in a research setting.23 reference implications as with classroom instruction, traditional reference practice emphasizes a prescriptive path for research that involves analyzing which aspects of a topic or alternate vocabulary will be most relevant to a search before search-term entry. open and closed questioning techniques encourage users to think about different facets of their topic, such as time period, location, and type of information (e.g., statistics) that might be relevant. an enhanced implementation of autocomplete can incorporate these best practices from the reference interview into the list of suggestions to aid unmediated searching. one way this might be incorporated is through presenting faceted results that change on the basis of user selection of the type and nature of information they are looking for, such as a time period, format, or subject. for broadcast and federated searching interfaces, this could extend into the results users are then presented with, specifically attempting to use items or databases on the basis of suggestions made during the search entry phase, rather than presenting users with a multitude of options for users to make sense of, some of which may be irrelevant to the actual information need. finally, the findings on use of autocomplete also have implications for search-results pages. many of the common uses (e.g., spelling suggestions and additional search-term suggestion) also should be standard on results pages. this, too, is a common feature of commercial interfaces. bing, for example, includes a related searches feature (on the left of a standard results page), that suggests context-specific search terms based on the query. this feature is also part of their api (http://www.bing.com/developers/s/apibasics.html). providing these reference-without-alibrarian features is essential both in establishing user confidence in library research tools and in developing research skills and an understanding of the information literacy concepts necessary to becoming better researchers. our autocomplete use findings draw attention to user needs and library support across search processes; specifically, autocomplete functionality offers support while forming search queries and can improve the results of user searching. for this reason, we recommend that autocomplete functionality be investigated for implementation across all library interfaces and websites to provide unified support for user searches. the benefits that can be realized from autocomplete can be maximized by consulting with reference and instruction personnel on the benefits noted above and collaboratively devising best practices for integrating autocomplete results into searchstrategy formulation and classroom-teaching workflows. http://www.bing.com/developers/s/apibasics.html autocomplete as a research tool | ward, hahn, and

primo new user interface: usability testing and local customizations implemented in response blake lee galbreath, corey johnson, and erin hvizdak information technology and libraries | june 2018 10 blake lee galbreath (blake.galbreath@wsu.edu) is core services librarian, corey johnson (coreyj@wsu.edu) is instruction and assessment librarian, and erin hvizdak (erin.hvizdak@wsu.edu) is reference and instruction librarian, washington state university. abstract washington state university was the first library system of its 39-member consortium to migrate to primo new user interface. following this migration, we conducted a usability study in july 2017 to better understand how our users fared when the new user interface deviated significantly from the classic interface. from this study, we learned that users had little difficulty using basic and advanced search, signing into and out of primo, and navigating their account. in other areas, where the difference between the two interfaces was more pronounced, study participants experienced more difficulty. finally, we present customizations implemented at washington state university to the design of the interface to help alleviate the observed issues. introduction a july 2017 usability study by washington state university (wsu) libraries was the final segment of a sixmonth process for migrating to the new user interface of ex libris primo called primo new ui. wsu libraries assembled a working group in december 2016 to plan for the migration from the classic interface to primo new ui and met bi-weekly through may 2017. to start, the primo new ui working group attempted to answer some baseline questions: what can and cannot be customized in the new interface? how, and according to what timeline, should we introduce the new interface to our library patrons? what methods could be used to assess the new interface? this working group customized the look and feel of the new interface to conform to wsu branding and then released a beta version of primo new ui in march, leaving the older interface (primo classic) as the primary means of access to primo but allowing users to enter and test the beta version of the new interface. in early may (at the start of the summer semester), the prominence of the old and new interfaces was reversed, making primo new ui the default interface but leaving the possibility of continued access to primo classic. the older interface was removed from public access in mid-august, just prior to the start of the fall semester. the public had the opportunity to work with the beta version from march to may and then another two months experience with the production release by the time the usability study took place in july 2017. the remainder of this paper will focus on the details of this usability study. mailto:blake.galbreath@wsu.edu mailto:coreyj@wsu.edu mailto:erin.hvizdak@wsu.edu primo new user interface | galbreath, johnson, and hvizdak 11 https://doi.org/10.6017/ital.v37i2.10191 research questions primo new ui was the name given to the new front end of the primo discovery layer, which was made available to customers in august 2016. according to ex libris, “its design is based on user studies and feedback to address the different needs of different types of users.”1 we were primarily interested in understanding the usability of the essential functionalities of primo new ui, especially where the design of the new interface deviated significantly from the classic interface (taking local customizations into account). for example, we noted that the new interface introduced the following differences to the user (this ordinal list corresponds to the number labels in figure 1): 1. basic search tabs were expressed as drop-downs. 2. the advanced search link was less prominent than it was with our customized shape and color in the classic interface. 3. main menu items were located in a separate area from the sign in and my account links. 4. my favorites and help/chat icons were located together and in a new section of the top navigation bar. 5. sign in and my account links were hidden beneath a “guest” label. 6. facet values were no longer associated with checkboxes or underlining upon hover. 7. availability statuses were expressed through colored text. figure 1. basic search screen in primo new ui. we also observed a fundamental change in the structure of the record in primo new ui: the horizontally oriented and tabbed structure of the classic record (see figure 2) was converted to a vertically oriented and non-tabbed structure in the new interface (see figure 3). additionally, the tabbed structure of the classic interface opened in a frame of the brief results area, while the same information was displayed on the full display page of the new interface. the options displayed in these areas are known as get it and view it (although we locally branded our sections availability and request options and access options, information technology and libraries | june 2018 12 respectively). therefore, we were eager to see how this change in layout might affect a participant’s ability to find get it and view it information on the full display page. taking the above observations into account, we formulated the following questions: 1. will the participant be able to find and use the basic search functionality? 2. will the participant be able to understand the availability information of the brief results? 3. will the participant be able to find and use the sign in and sign out features? 4. will the participant be able to understand the behavior of the facets? 5. will the participant be able to find and use the actions menu? (see the “send to” boxed area in figure 3.) 6. will the participant be able to navigate the get it and view it areas of the full display page? (see the “availability and request options” boxed area in figure 3.) 7. will the participant be able to navigate the my account area? 8. will the participant be able to find and use the help/chat and my favorites icons? 9. will the participant be able to find and use the advanced search functionality? 10. will the participant be able to find and use the main menu items? (see figure 1, number 3.) figure 2. horizontally oriented and tabbed layout of primo classic. literature review 2012 witnessed a flurry of studies involving primo classic. majors compared the experiences of users within the following discovery interfaces: encore synergy, summon, worldcat local, primo central, and ebsco discovery service. the study used undergraduate students enrolled at the university of colorado and focused on common undergraduate searching activities. each interface was tested by five or six participants who also completed an exit survey. observations specific to the primo interface noted that users had difficulty finding and using existing features, such as email and e-shelf, and difficulty connecting their failed searches to interlibrary loan functionality.2 primo new user interface | galbreath, johnson, and hvizdak 13 https://doi.org/10.6017/ital.v37i2.10191 figure 3. vertically oriented and non-tabbed layout of primo new ui. comeaux noted issues relating to terminology and the display of services during usability testing carried out at tulane university. twenty people, including undergraduates, graduates, and faculty members, participated in this study, which tested five typical information-seeking scenarios. the study found several problems related to terminology. for example, participants did not fully understand the meaning of the expand my results functionality.3 participants also did not understand that the display text “no full-text” could be used to order an item via interlibrary loan. 4 the study also concluded that the mixed presentation of differing resource types (e.g., books, articles, reviews) was confusing for patrons who were attempting known-item searches.5 jarrett documented a usability study conducted at flinders university library. the aims of the study were to determine user perceptions regarding the usability of the discovery layer, the relevance of the information retrieved, and the user experiences of this search interface compared to other interfaces. 6 the usability portion of the study scored the participants’ completion of tasks in the primo discovery layer as difficult, confusing, neutral, or straightforward. scores indicated that participants had difficulty determining different editions of a book, locating a local thesis, and placing an item on hold. the investigators also observed that students had issues signing into primo and distinguishing between journals and journal articles.7 information technology and libraries | june 2018 14 nichols et al. conducted a usability test on a newly implemented primo instance at the university of vermont libraries in 2012. their research questions were designed to understand primo’s design, functionality, and layout.8 the majority of the participants were undergraduate students. similar to comeaux, confusion occurred when participants had to find specific or relevant records within longer sets of results.9 nichols et al. also noticed that test subjects had difficulty navigating and finding information in the primo tabbed structure. like jarrett, nichols et al. noted that participants had difficulty distinguishing between the journals and articles.10 similar to majors, participants in nichols et al. had difficulty finding certain primo functionality, such as email, the e-shelf, and the feature to open items in a new window.11 the investigators concluded that these tools were difficult to find because they were buried too deep in the interface. the university of kansas libraries conducted two usability studies on primo. the first study took place during the 2012–13 academic year and involved 27 participants, including undergraduate, graduate, and professional students, who performed four to five main tasks in two separate sessions. similar to other studies, participants experienced great difficulty using the save to e-shelf and email citation tools.12 kliewer et al. conducted the second usability study in 2016, which focused primarily on student satisfaction with the primo discovery tool. thirty undergraduates participated in this study that collected both qualitative and quantitative data. in contrast to most usability studies of discovery services, this study allowed participants to explore primo with open-ended searches to more closely mimic natural searching strategies. results of the study indicated that the participants preferred basic search to advanced search, used facets (but not enough to maximize their searching potential), rarely moved beyond the first page of search results, and experienced difficulties using the link resolver. in response to the latter, a primo working group clarified language on the link resolver page to better differentiate between links to articles and links to journals.13 brett, lierman, and turner conducted a usability study at the university of houston libraries focusing primarily on undergraduate students. users were able to complete the assigned tasks, but the majority did not do so in the most efficient manner. that is, the participants did not take full advantage of primo functionality, such as facets, holds, and recalls. additionally, some participants exhibited difficulty deciphering among the terms journals, journal articles, and newspaper articles. another difficulty participants experienced was knowing what further steps to take once they had successfully found an item in the results list. for example, participants had trouble locating stacks guides, finding request features, and using call numbers. the researchers concluded that many of the issues witnessed in this usability study could be mitigated via library instruction.14 usability testing of primo new ui has recently begun to take a foothold in academic libraries. in addition to conducting usability testing on the primo classic in april 2015 (5 participants, 5–6 tasks), researchers at boston university carried out both preand post-launch testing of the new interface in december 2016 and april 2017, respectively. pre-launch testing with five student participants identified issues with “labelling, locating links to online services, availability statement links in full results, [and] my favorites.”15 after completing fixes, post-launch testing with four students (2 infrequent users, 2 frequent) found that they were able to easily complete tasks, use filters, save results, and find links to online resources. usage statistics for the new interface, compared to classic, also showed an increased use of facets after fixes, and an increase in the use of some features but decrease in the use of others, providing information on what features warranted further examination.16 primo new user interface | galbreath, johnson, and hvizdak 15 https://doi.org/10.6017/ital.v37i2.10191 california state university (csu) libraries conducted usability studies on primo new ui with 24 participants (undergraduate students, graduate students, and faculty) across five csu campuses. five standard tasks were required: find a specific book, find a specific film, find a peer-reviewed journal article, find an item in the csu network not owned locally, and find a newspaper article. each campus added additional questions based on local needs. participants were overwhelmingly positive about the interface look and feel, ease of use, and speed of the system. the success rate for each task varied across the campuses, with participants having greater success on simple tasks such as finding a specific or known item and mixed results on more difficult tasks including using scopes, understanding icons and elements of the frbr record, and facets. steps were taken to relabel and rearrange the scopes and facets so that they were more meaningful to users, and frbr icons were replaced. the authors concluded that primo is an ideal solution to incorporate both global changes and local preference because of its customizability.17 university of washington libraries conducted usability studies on the classic and new primo interfaces. the primo new ui study observed 12 participants. each 60-minute session included an orientation, pre and post-tests, tasks, and follow-up questions. difficulties were noted with terminology, the site logo, the inability to select multiple facets, unclear navigation, volume requesting, advanced search logic, the pin location in item details, and the date facet. a/b testing with 12 participants (from both the new and c lassic ui studies) revealed the need to fix the sign-in prompt for my favorites, enable libraries to add custom actions to the actions menu, add a sort option for favorites in the new interface, add the ability to rearrange elements on a single item page, and add zotero support. overall, participants preferred the new interface. generally, participants easily completed basic tasks, such as known-item searches, searches for course reserves, and open searches, but had more difficulty with article subject searching, audio/visual subject searching, and print-volume searching, which was consistent from the classic to the new interfaces for student participants.18 method we conducted a diagnostic usability evaluation of primo new ui using eight participants, whom we recruited from the wsu faculty, staff, and student populations. in the end, we received a skewed distribution among the categories: three members of staff and five students (two undergraduate students and three graduate students). the initial composition of the participants comprised a greater number of undergraduate students, but substitution created the final makeup. all the study participants had some exposure to primo classic in the past. we recruited participants by hanging flyers around the libraries of our pullman campus and the adjoining student commons area. we offered the participants $15 in exchange for their time, which we advertised as being a maximum of one hour. the usability test was designed by a team of three library staff, one from systems (it) and two from research services (reference/instruction). two of us were present at each session, one to read the tasks aloud and the other to document the session. we used camtasia to record each session so that we would have the ability to return to it later if we needed to verify our notes or other specifics of the session. we stored the recordings on a secured share of the internal library drive. we received an institutional review board certificate of exemption (irb #16190) to conduct this study. information technology and libraries | june 2018 16 this usability test comprised eleven tasks (see appendix a) to test the research questions described above. the tasks were drafted in consultation with the ex libris set of recommendations for conducting primo usability testing.19 each investigator drew their conclusions as to the participants’ successes and failures. we then met as a group to form a consensus regarding task success and failure (see appendix b). we met to discuss the patterns that emerged and to formulate remedies to problems we perceived as hindering student success. results for each of the ten research questions below, consult appendix b to see details regarding the associated tasks and how each participant approached and completed each task. task set(s) related to research question 1: will the participant be able to find and use the basic search functionality? this was one of the easier tasks for the participants to complete. some participants did not follow the task literally to find their favorite book or movie, but rather completed a search for an item or topic of interest to them. all the participants completed this task successfully. task set(s) related to research question 2: will the participant be able to understand the availability information of the brief results? the majority of the participants understood that the availability text and its color represented important access information. however, there were instances where the color of the availability status was in conflict with its text. this led at least one participant to evaluate the availability of a resource incorrectly. task set(s) related to research question 3: will the participant be able to find and use the sign in and sign out features? the participants all successfully completed this task. participants used multiple methods to sign in: the guest link in the top navigation bar, the sign in link from the ellipsis main menu item, and the get it sign in link on the full display page. all participants signed out via the user link in the top navigation bar. task set(s) related to research question 4: will the participant be able to understand the behavior of the facets? almost all of the participants were able to select the articles facet without issue. one person, however, misunderstood the include behavior of the facets. instead of using the include behavior, this participant used the exclude behavior to remove all facets other than the articles facet. only two participants attempted to use the print books facet to complete the task, “from the list of results, find a print book that you would need to order from another library.” instead, the other 75 percent simply scanned the list of results to find the same information. five out of the eight participants attempted to find the peer-reviewed facet when completing the task to choose any peer-reviewed article from a results list: three were successful, while one selected the newspaper articles facet, and another selected the reviews facet. task set(s) related to research question 5: will the participant be able to find and use the actions menu? the tasks related to the actions menu (copy a citation and email a record) were some of the most difficult for the participants: two were successful, three had some difficulty, and three were unsuccessful. of those primo new user interface | galbreath, johnson, and hvizdak 17 https://doi.org/10.6017/ital.v37i2.10191 who experienced difficulty, one seemed not to understand the task fully; this participant found and copied the citation, but then spent additional time looking for a “clipboard.” the other two participants were both distracted by competing areas of interest: the citations section of the full display and the section headings of the full display. of those who were unsuccessful, one suffered from a technical issue that ex libris needs to resolve (the functionality to expand the list of action items failed), one did not seem to understand what a citation was when they found it, and another could not find the email functionality. this last subject continued searching in the ellipsis area of the main menu, in the my account area, and the facets, but ultimately never found the email icon in the scrolling section of the actions menu. task set(s) related to research question 6: will the participant be able to navigate the get it and view it areas of the full display page? three participants experienced substantial difficulty in completing this set of tasks. these participants were distracted by the styled show libraries and stack chart buttons on the full display page that were competing for attention with the requesting options. task set(s) related to research question 7: will the participant be able to navigate the my account area? all of the participants completed this task successfully. four participants located the back-arrow icon to exit the my account area, while the other four participants used alternate methods: using the library logo, selecting the new search button, and signing out of primo. task set(s) related to research question 8: will the participant be able to find and use the help/chat and my favorites icons? participants encountered very little difficulty in finding a way to procure help and chat with a librarian, with one exception. participant 2 immediately navigated to and opened our help/chat icon, but then moved away from this service because it opened in a new tab. this same participant, along with three others, had a more difficult time finding and deciding to use the pin this item icon than did the three participants who completed the same task with ease. the remaining participant failed to complete this task because they could not find the my favorites area of primo. task set(s) related to research question 9: will the participant be able to find and use the advanced search functionality? one participant had more trouble finding the advanced search functionality than the other seven. another experienced a technical difficulty, in which the primo screen froze during the experiment, and we had to begin the task anew. the remaining six people easily finished the tasks. task set(s) related to research question 10: will the participant be able to find and use the main menu items? the majority of the participants completed this task with ease, navigating to the databases link in the main menu items. one participant, however, was confused by the term database but was able to succeed once we provided a brief definition of the term. the remaining two participants were further confused by the term and instead entered general search terms into the primo search bar. these two participants failed to find the list of databases. discussion information technology and libraries | june 2018 18 study participants completed four of our task sets with relative ease: using basic search (see research question 1 above), signing into and out of primo (see research question 3 above), navigating their my account area (see research question 7 above), and using advanced search (see research question 9 above). there was one exception: one participant experienced minor trouble finding the advanced search link, checking first among the drop-down options on our basic search page. subsequent and unrelated to this study, wsu elected to eliminate the first set of drop-down options from our primo landing page. further testing might tell us if this elimination in the number of drop-down options has effectively made the advanced search link more prominent for users. also, the ease with which participants were able to use items located underneath the “guest” label contradicted our expectations. we predicted that this opacity would cause users issues, but it did not seem to deter them. from this, we concluded that the placement of the sign in options in the upper right corner is sufficient to maintain continuity. participants encountered a moderate degree of difficulty completing two task sets: determining availability statuses and navigating the get it area of the full display page. concerning availability, participants were quick to understand that statuses such as “check holdings” relayed that the item was not available. the participants were also keen to notice that green availability statuses implied access while non -green availability statuses implied non-access. however, per the design of the new interface, certain non-green links became green after opening the full display page of primo. this was a significant deviation from the classic interface, where colors indicating availability status did not change. this design element misled one participant. of note, we did not observe participants experiencing issues with the converted format of the get it and view it areas (see figures 2 and 3) per se. however, we did notice that three of our participants were unnecessarily distracted by the show libraries link when trying to find resource sharing options because wsu had previously styled the show libraries links with color and shape. therefore, our local branding in this area impeded usability and led us to rethink the hierarchy of actions on the full display page. similar to comments made by demars, study participants also remarked that the layout of the full display was cluttered and difficult to read.20 we therefore took steps to make this page more readable for the viewer. study participants displayed the greatest difficulty completing the remaining four task sets: selecting a main menu item, refining a search via the facets, using the actions menu, and navigating the my favorites functionality. however, web design was not necessarily the culprit in all four areas. three participants experienced difficulty finding the databases link (a main menu item). after further discussion, it became apparent that this trouble related not to usability but to information literacy—they did not understand the term databases. therefore, like majors and comeaux,21 we recognize the recurring issue of library jargon, and like brett, lierman, and turner,22 we believe that this issue would best be mitigated via library instruction. in agreement with the literature, two participants selected the incorrect facet because they had difficulty distinguishing among the terms articles, newspaper articles, reviews and peer-reviewed.23 further, one of these participants experienced even more difficulty because of not understanding the inherent functionality of the facet values. that is, this participant did not grasp that the facet value links performed an inclusion process by default. to the contrary, this person believed that they would have had to exclude all unwanted facet values to arrive at the wanted facet value. the change in facet behavior between classic and new interfaces likely caused this confusion. in primo classic, wsu had installed a local customization that provided checkboxes and underlining upon hover for each facet value. the new interface did not primo new user interface | galbreath, johnson, and hvizdak 19 https://doi.org/10.6017/ital.v37i2.10191 provide either one of these clues to the user. additionally, we observed, similar to kliewer et al. and brett, lierman, and turner, that participants oftentimes preferred to scan the results list over refining their search via faceting.24 this finding also matches a 2014 ex libris user study indicating that users are easily confused by too many interface options and thus tend to ignore them.25 regarding the actions menu, the majority of the participants attempted to find the email icon in the correct section of the full display page (i.e., the “send to” section). however, because of a technical issue in the design of the new interface, the email icon was not always present for the participant to find. for others, it was difficult to reach the icon even when it was present as participants had to click the right arrow three to four times to navigate past all the citation manager icons. this observed difficulty in finding existing functionalities in primo echoes that cited by majors and nichols et al.26 participants also experienced significant difficulty deciphering between the similarly named functionalities of the citation icon and the citations section of the full display page. as a result of this observed difficulty, we concluded that differentiating sections of the page with distinct naming conventions would be beneficial to users. like the results reported by boston university, our study participants encountered significant issues when trying to save items into their my favorites list.27 we noticed that participants had difficulty making connections between the icons named keep this item/remove this item and the my favorites area. during testing, it was clear that many of the participants were drawn to the pin icon for the correctly anticipated functionality but then were confused that the tooltips did not include any language resembling “my favorites.” from this last observation, we surmised that providing continuity in language between these icons and the my favorites area would increase usability for our library patrons. pepitone reported problems with the placement of the my favorites pin icon,28 but we observed this being less of a problem than the actual terminology used to name the pin icon. beyond success and failure, a 2014 ex libris user study suggested that academic level and discipline play a key role in user behavior.29 however, we were unable to draw meaningful conclusions among user groups because of our small and homogenous participant pool. decisions made in response to usability results declined to change facets. although one participant did not understand the inclusion mechanism of the facet values, we declined to investigate a customization in this area. according to the primo august 2017 release notes, ex libris plans to make considerable changes to the faceting functionality.30 therefore, we decided to wait until after this release to reassess whether customization was warranted. implemented a change labels citations. we observed confusion between the citation icon of the actions menu and the section of the full display page labeled “citations.” to differentiate between the two items, we changed the actions menu icon text to “cite this item” (see figure 4) and the heading for the citations section to “references cited” (see figure 5). information technology and libraries | june 2018 20 figure 4. cite this item icon of the actions menu. figure 5. references cited section of the full display page. my favorites. there was a mismatch among the tooltip texts of the my favorites icons. we changed the tooltip language for the “keep this item” pin to read “add to my favorites” (see figure 6) and the tooltip language for the “unpin this item” pin to read “remove from my favorites” (see figure 7). figure 6. add to my favorites language for my favorites tooltip. figure 7. remove from my favorites language for my favorites tooltip. availability statuses. per the design of the new interface, certain non-green links became green after opening the full display page of primo new ui. we implemented css code to retain the non-green coloring of the availability statuses after opening the full display. in this case, “check holdings” remains orange (see figure 8). figure 8. availability status color of brief display, before and after opening the full display. primo new user interface | galbreath, johnson, and hvizdak 21 https://doi.org/10.6017/ital.v37i2.10191 link removal full display page headings. there was confusion as to the function of the headings on the full display page. these are anchor tags, but patrons clicked on them as if they were functional links. no patrons used the headings successfully. therefore, we hid the headings section via css (see figure 9). figure 9. removal of headings on full display page. links to other institutions. we observed participants attempting to use the links to other institutions to place resource sharing requests. therefore, we removed the hyperlinking functionality of the links in the list, via css (see figure 10). figure 10. neutralization of links to other institutions. prioritized the emphasis of certain functionalities request options and show libraries buttons. it is usually more important to be able to place a request than find the names of other institutions who own an item. however, the show libraries button was originally styled with crimson coloring, which drew unwarranted attention, while the requesting links were not. therefore, we added styling to the resource-sharing links and removed styling from the show libraries button via css (see figure 11). figure 11. resource sharing link with crimson color, show libraries removed of styling. information technology and libraries | june 2018 22 e-mail icon. we observed that the e-mail icon of the actions menu was difficult to find. therefore, we decreased the number of icons and moved the emailing functionality to the left side of the actions menu (see figure 12). figure 12. email icon prioritized over citation manager icons. contrast and separation full display page sections. participants noted that the information on the full display page tended to run together. to remedy, we created higher contrast between the foreground and background of the page sections via css. we also styled the section titles and dividers with color, among other edits (see figure 13). figure 13. separated sections of full display page (see figure 3 to compare to the new ui default full display page design). primo new user interface | galbreath, johnson, and hvizdak 23 https://doi.org/10.6017/ital.v37i2.10191 conclusion while providing one of the first studies on primo new ui, we acknowledge several limitations. previous studies on primo had larger study populations compared to this one (which had eight participants). however, we adhered to nielsen’s findings that usability studies uncover most design deficiencies with five or more participants.31 additionally, the scope of this study was limited to the usability of the desktop view. we recommend further studies that will concentrate on accessibility compliance and that will test the interface on mobile devices. regarding the study design, the question arose as to whether the participants’ difficulties reflected poor design functionality or a misunderstanding of library terminology (as noted by majors and comeaux).32 the researchers did not carry out pre-tests or an assessment of participants’ level of existing knowledge. this limitation is almost always unavoidable, however, as a task list will always risk not fitting the skills or knowledge of every participant. the lack of some features’ use also might have been because of study design. while not using the facets may reflect that participants are unaware of them, it could also be from the fact that they never had to scroll past the first few items to find the needed resource. users might have felt a greater need to use the facets had we asked more difficult discovery tasks. the study also contained an investigative bias in that the researchers were part of the working group that developed the customized interface, and then tested those customizations. this bias could have been reduced if the study had used researchers who were not a part of the same group that made these customizations. despite these limitations, there are still key findings of note. tasks that participants completed with the greatest ease mapped to those that we assume they do most often, which included basic searching for materials and accessing account information. tasks beyond these basics proved to be more difficult. this raises the question of whether difficulties were really a function of the interface design or if they reflected ongoing literacy issues. therefore, it is crucial that designers work with public services and instruction librarians to identify areas where users might be well-served by making certain functionalities more userfriendly and creating educational and training opportunities to increase awareness of these functionalities.33 bringing diverse perspectives into the study is also crucial so that researchers can discover and be more conscious of commonalities in design and literacy needs, particularly regarding advanced tasks. information technology and libraries | june 2018 24 appendix a: usability tasks note: search it is the local branding for primo at

question #10: associated task(s): librarians and technology skill acquisition: issues and perspectives | riley-huff and rholes 129 debra a. riley-huff and julia m. rholes librarians and technology skill acquisition: issues and perspectives qualified individuals to fill these technology-driven librarian roles in our libraries and if so why? how are qualifications acquired and what are are they, besides a moving target? there appears to be two major convergent trends influencing this uncertain phenomenon. the first is what is perceived as “lack of awareness” and consensus about what the core of lis needs to be or to become in order to offer real value in a constantly changing and competitive information landscape.5 the other trend centers on the role of lis education and the continuing questions regarding its direction, efficacy, and ability to prepare future librarians for the modern information professions of now and the future. while changes are apparent it appears many lis programs are still operating on a two-track model of “traditional librarians and information managers” and there are enough questions in this area to warrant further investigation and inquiry.6 ■■ literature review most of the literature pertaining to the readiness of librarians to work in increasingly technical environments, centers on lis education. this certainly makes sense given the assumed qualifications the degree confers. scant literature focuses solely on the core of the librarians’ professional identity, workplace culture, and institutional historical perspectives related to qualifications; however, allusions to “redefining” lis are often found in lis education literature. there is limited research on preprofessional or even professional in-service training although calls for such research have been made repeatedly. a key study on lis education is the 2000 kaliper report, issued when the impact of technology in libraries was clearly reaching saturation.7 the report is the product of an analysis project with a goal of examining new trends in lis education. the report lists six trends including three of which are pertinent to the investigation of technology inclusion in lis programs. these trends note that in 2000, lis programs were beginning to address a more broad range of information problems and environments, programs were increasing it content into the curriculum, and several programs were beginning to offer specializations within the curriculum, though not ones with a heavy technology focus. in a widely cited curriculum study in 2004, markey completed a comprehensive examination of 55 libraries are increasingly searching for and employing librarians with significant technology skill sets. this article reports on a study conducted to determine how well prepared librarians are for their positions in academic libraries, how they acquired their skillss and how difficult they are to hire and retain. the examination entails a close look at ala-accredited lis program technology course offerings and dovetails a dual survey designed to capture experiences and perspectives from practitioners, both library administrators and librarianss who have significant technology roles. a recent oclc report on research libraries, risk, and systemic change discusses what arl directors perceive as the highest risks to their libraries.1 the administrators reported on several high risks in the area of human resources including high-risk conditions in recruitment, training, and job pools. the oclc report notes that recruitment and retention is difficult due to the competitive environment and the reduction in the pool of qualified candidates. why precisely do administrators perceive that there is a scarcity of qualified candidates? changes in libraries, most of which have been brought on by the digital age, are reflected in the need for a stronger technological type of librarianship—not simply because technology is there to be taken advantage of, but because “information” by nature has found its dominion as the supreme commodity perfectly transported on bits. it follows, if information is your profession, you are no longer on paper. that lis is becoming an increasingly technology-driven profession is both recognized and documented. a noted trend particularly in academic libraries is a move away from simply redefining traditional or existing library roles altogether in favor of new and completely redesigned job profiles.2 this trend verifies actions by library administrators who are increasingly seeking librarians with a wider range of information technology (it) skills to meet the demands of users who are accessing information through technology.3 johnson states the need well as we need an integrated understanding of human needs and their relationships to information systems and social structures. we need unifying principles that illuminate the role of information in both computation and cognition, in both communication and community. we need information professionals who can apply these principles to synthesize human-centered and technological perspectives.4 the questions then become, is there a scarcity of debra a. riley-huff (rileyhuf@olemiss.edu) is web services librarian, university of mississippi libraries, university, miss. julia m. rholes (jrholes@olemiss.edu) is dean of libraries, university of mississippi libraries, university, mississippi. 130 information technology and libraries | september 2011 academic libraries had embarked on an unprecedented increase in filling librarian positions with professionals who do not have a master’s degree in library science.13 citing the association of research libraries annual salary statistics, among a variety of positions being filled by other professionals a substantial number are going to those in technology fields such as systems and instructional technology. in the mid 2000s, suggestions that library schools needed to work more closely with computer science departments began coming up more often. obstacles to these types of partnerships were noted as computer science departments failed to see the advantage offered by library science faculty as well as being wary of taking on a “softening” by the inclusion of what is perceived as a “soft science.”14 in response, most library schools have added courses in computing, but many still question the adequacy. more recently there have been increasing calls from within lis for more research into lis education and professional practice. in 2006, a study by mckinney comparing proposed “ala core competencies” to what was actually being taught in ala-accredited curricula, shed some light on what is currently offered in the core of lis education.15 the study found that the core competency required most often in ala-accredited programs were “knowledge organization” or cataloging (94.6 percent), “professional ethics” (80.4 percent), “knowledge dissemination” or reference (73.2 percent), “knowledge inquiry” or research (66.1 percent), and “technical knowledge” or technology foundations (66.1 percent).16 these courses map well to ala core competencies but the question in the digital age, is one, not even universally required, technology-related course adequate for a career in lis? the literature would seem to reflect that it is not. 2007 saw many calls for studies of lis education using methods that not only examined course curricula but that also sought evidence of outcomes by those working in the field.17 an interest in studies reporting on employers’ views, graduates’ workplace experiences, and if possible longitudinal studies have been outwardly requested.18 indications are that those in library work environments can play a vital role in shaping the future course of lis education and preprofessional training by providing targeted research, data, and evidence of where weaknesses are currently being experienced and what changes are driving new scenarios. the most current literature points out both areas of technology deficiencies and emerging opportunities in libraries. areas with an apparent need for immediate improvement are the continuing integration of third-party web 2.0 application programming interfaces (apis) and social networking platforms.19 debates about job titles and labels continue but the actuality is that the number of adequately trained digital librarians has not kept up with the demand.20 modern libraries require those in technology-related roles to have broad or ala-accredited lis programs looking for change between the years 2000 and 2002.8 markey’s study revealed that while there were improvements in the number of it-related courses offered and required throughout programs, they were still limited overall with the emphasis continuing to be on the core curriculum consisting of foundations, reference, organization, and management. one of the important points markey makes is the considerable challenge involved in retraining or acquiring knowledgeable faculty to teach relevant it courses. the focus on lis education issues came to the fore in 2004 when michael gorman released a pair of articles asserting that there was a crisis in lis education, namely an assault on lis by what gorman referred to as “information science,” “information studies” and “information technology.”9 gorman’s papers sought to establish that there is a de facto competition between information science courses, which he characterized as courses with a computational focus and lis courses, which composed core librarianship courses, those tending to be the more user focused and organizational. gorman claimed lis faculty were being marginalized in favor of information science and made further claims regarding gender roles within the profession along the alleged lis/is split. gorman also noted that there was no consensus about how “librarianship” should be defined coming from either ala or the lis graduate programs. the articles were not without controversy, spurring a flurry of discussion in the library community, which spawned several follow up articles. dillon and norris rallied against the library vs. information science argument as a premise, which has no bearing on the reality of what is happening in lis and does nothing but create yet another distracting disagreement over labels.10 others argued for the increasing inclusion of technology courses in lis education, as estabrook put it, librarianship without a strong linkage to technology (and it’s capacity to extend our work) will become a mastodon. technology without reference to the core library principles of information organization and access is deracinated.11 as the future of lis was being hotly debated, voices in the field were issuing warnings that obstacles were being encountered finding qualified librarians with the requisite technology skills necessary to take on new roles in the library. in 2007, johnson made the case for the increasing need for new areas of emphasis in lis, including specializations such as geographic information systems by pointing out that it is not so much the granular training that is expected of lis education but a higher level technology skill set that allows for the ability to move into these specializations, identify what is needed, assess problems, and make decisions.12 in 2006, neal noted that librarians and technology skill acquisition: issues and perspectives | riley-huff and rholes 131 by examination of course catalogs and surveys of both library administrators and technology librarians. the lis educational data was obtained by inspecting course catalogs. course catalogs and website curriculum pages from all ala-accredited lis programs in the united states, canada, and puerto rico were examined in december 2009 for the inclusion of technology-related courses. the catalogs examined were for the 2009–10 academic year. spanish and french catalogs were translated. each available course description was reviewed and those courses with a primary technology component were identified. in a secondary examination the selected courses were closely inspected for the exact technology focus and the primary subject content was noted for each course. courses were then separated into categories by areas of focus and tabulated. a targeted survey identified practicing technology librarians’ perspectives on their level of preparation and continuing skill level needs based on actual job demands. in this survey, librarians with significant technology roles was defined as “for the purposes of this survey a librarian with a significant technology role would be any librarian whose job would very likely be considered “it” if they were not in a library and whose job titles contain words like “systems, digital, web, electronic, network, database, automation, and whose job involves maintaining and/or building various it infrastructures.” the survey was posted on various library and library technology electronic discussion lists in december 2009 and was available for two weeks. library administrative perspectives were also gained through a targeted survey aimed at those with an administrative role of department head or higher. the survey was designed to capture the reported experience library administrators have had with librarians in significant technology roles, primarily as it relates to skill levels, availability, hiring, and retention. this survey was posted on to various library administrative and technology discussion lists in december 2009 and was also available for two weeks. both surveys included many similar questions to compare and contrast viewpoints. results were tabulated to form an overarching picture and some relevant comparisons were made. there are limitations and inherent issues with this type of research. catalog examinations when completed by qualified librarians can hold great accuracy; however, the introduction of bias or misinterpretation is always possible.26 when categorizing courses, the authors reviewed course descriptions three separate times to ensure accuracy. courses in doubt were reviewed again with knowledgeable colleagues to obtain a consensus. surveys designed to capture perspectives, views, and experiences are by nature highly subjective and provide data that is both qualitative and quantitative. tabulated data was given strictly simple numerical representation to provide a factual picture of what was reported. specialized competencies in areas such as web development, database design, and management paired with a good working knowledge of classification formats such as xml, marc, ead, rdf and dublin core. educational technology (et) has been identified as an area of expected growth opportunity for libraries and there have been suggestions that more lis programs should partner with et programs to improve lis technology offerings, skills and preprofessional training.21 lis program change, including the apparent coalescing of information technology focused education would appear to be demonstrated by the ischool or ifield caucus of ala accredited programs, however the literature is not clear on if that is actually being evidenced. the ischools organization started in as collective in 2005 with a goal of advancing information science. ischools incorporate a multidisciplinary approach and those with a library science focus are ala accredited.22 a 2009 study interestingly applied abbott’s theoretical framework used in the chaos of disciplines to the ifield.23 resulting in abstract yet relevant conclusions, abbott looks at change in a field through a sociological lens looking for patterns of fractal distinction over time. the study concluded that traditional lis education remained at the heart of the ifield movement and that the real change has been in locale, from libraries to location independent.24 hall’s 2009 study exploring the core of required courses across almost all ala accredited programs reveals that the core curriculum is still principle-centered, but it is focusing less on reference and intermediary activities with a definite shift toward research methods and information technology.25 ■■ method this research study was designed to capture a broad view of technology skill needs, skill availability, and skill acquisition in libraries, while still allowing for some areas of sharper focus on stakeholder perspectives. the four primary stakeholder groups in this study were identified as lis educators, lis students, working librarians, and library administrators. the research questions cover three main areas of technology skill acquisition and employment. one area is lis education and whether the status of all technology course offerings has changed in recent years in response to market demands. the second area is the experience of librarians with significant technology roles with regards to job availability, readiness, and technology skill acquisition. the third area is, the perception of library administrators regarding the availability and readiness of librarians with technology roles. to cover the research questions and provide a broad situational view, the research was triangulated and aimed at the three question areas. data collection was accomplished 132 information technology and libraries | september 2011 may arguably be considered description or cataloging. metadata was included because it is an integral part of many new digital services. the categories are presented in column 1, the total number of courses offered is presented in column 2. the number of advanced courses available within each category total is further broken out into parenthesis. some programs offered more than one course in a given category; hence the percentage of programs offering at least one course is given in column 3. additionally, although the librarian survey was targeted to “those with significant technology roles,” it would appear that the definition of “significant” seemed to vary in interpretation by the respondents. this is discussed in further detail in the findings. given the limitations of this type of research, the authors did not attempt to find definite correlations, however trends and patterns are clearly revealed. ■■ catalog findings course catalogs from all 57 ala-accredited programs in the united states, canada, and puerto rico were examined for the inclusion of technology-related courses. a total of 439 technology-related courses were offered across the 57 lis programs, including certificate program course offerings. the total number of technology-related courses offered by program ranged from 2 to 20. the mean number of courses offered per program was 7.7, the median was 10, and the mode was 4. table 1 shows the total number of technology courses being offered per program by matching them with the number of courses they offer. catalog course content descriptions were analyzed looking for a technology focus. the fifteen categories noted in table 2 were selected as representative of the technology-related courses offered. it is acknowledged that some course content may be overlapping, but each course was placed in only one category based on its primary content. note also the inclusion of “metadata markup” which table 1. number of technology-related courses being offered per program # of programs offering # of courses offered 1 offers 2 courses 6 offer 3 courses 8 offer 4 courses 6 offer 5

and rholes 133 ■■ perspectives on job availability, readiness and skill acquisition as previously noted in the method, two surveys were administered to collect participant viewpoint data pertinent to the study. reponses were carefully checked to determine whether they met the criteria for inclusion in the study. no attempt was made to disqualify respondents based solely on job title. it did appear that a significant number of non-target subjects did initially reply to the librarian survey, but quit the survey at the technology-related questions. final inclusion was based on either an it-related job title or if the respondent answered the technology questions regardless of job title. tables 3–5 report demographic response data. ■■ perspectives on job and candidate availability a 2009 study by matthew and pardue asked the question “what skills do librarians need in today’s world?”29 they sought to answer this question by performing a content analysis, spread over five months, of randomly selected jobs from ala’s joblist. what they found in the area of technology was a significant need for web development, an assessment of the course catalog facts reveals that there have been increases in the number of technology courses offered in lis programs, but is it enough? significant longitudinal data shows an increased emphasis in the area of metadata. a 2008 study of the total number of lis courses offering internet or electronic resources and metadata schemas, found that the number of programs offering such as being ten (17.5 percent) with only twelve metadata courses offered in total.27 current results show 43 metadata courses offered with 50 percent of lis programs offering at least one course. the lack of a solid basis in web 2.0 applications and integration as reported by aharony is confirmed by the current catalog data, with only 17 percent of programs offering a course.28 while at first glance it looks like many technology-related courses are currently being offered in lis programs, a closer inspection reveals cause for concern. many of these courses should be offered by 100 percent of lis programs and advanced courses in many areas should be offered as well. while there may be some overlap of content in some of these course descriptions, the percentages are still too low to deduce that lis graduates, without preprofessional technology experience or education, are really prepared to take on serious technology roles in academic libraries. table 3. response data responses administrative survey librarian survey total responses 185 382 total usable

information technology and libraries | september 2011 based on the difficulty rating and the classifications were then averaged by difficulty. some respondents were unsure of difficulty ratings because the searches happened before their presence at their current library and those searches were excluded. position classifications with less than five searches were excluded from averaging and are marked “na” in table 6. the difficulty rubric is as follows: 1 = easy; 2 = not too bad, pretty straightforward search; 3 = a bit tough, the search was protracted; 4 = very difficult, required more than one search; 5 = unable to fill the position. it is to be noted that almost all levels of difficulties were reported for many classifications but that the overall average hiring difficulty rating was 2.48. a comparable set of questions was posted to the librarian survey. we asked librarians to report professional level technology positions they had held in the past five years along with any current job searches. 164 responses were received by people indicating that they had held such a position or were searching for one, with the total number of positions/searches being reported at 316 with some respondents reporting multiple positions. respondents reported having between one and five different positions with the average number being 1.92 jobs per respondent (see table 7). the respondents were also asked to give the position title for each position held or positions they were applying for as well as the difficulty encountered in obtaining the position. like the administrative report, job titles were project management, systems development, and systems applications. further they suggest that some librarians are using a substantial professional it skills subset. this article’s literature review points out that there are assertions being made that some technology-related librarian positions are difficult to fill and may in fact be filled by non-mls professionals. in the associated surveys the authors sought to capture data related to actual job availability, search experiences and perspectives by both library administration and librarians. note that both mls librarians and a few professional library it staff completed the survey. the distinction is made where appropriate. the survey asked library administrators if they had hired a technology professional position in the past five years. 146 responses were received and 100 respondents indicated that they had conducted such a search, with the total number of searches being reported at 167. of these searches, 22 did not meet the criteria for inclusion due to other missing data such as job title. the total reported number of librarian/professional level technology positions that were posted for hire by these respondents was 145 with some respondents reporting multiple searches for the same or different positions. respondents conducting searches reported having between 1 and 5 searches total with the average number being 1.45 per respondent. the respondents were also asked to provide the position title for each search, the difficulty encountered in conducting the search, and the success rate. job titles were divided into categories to ascertain how many positions in each category reported having a relevant search conducted. each search was then assigned a point value

and rholes 135 employment status for “newly minted” mls graduates having just entered the profession were asked in a survey “did specific information technology or computer skills lead to you getting a job?” the answer was a “resounding yes” by 66 percent of the respondents.33 experience is divided into categories to ascertain how many positions in each classification category. each position classification was then assigned a point value base on how the respondents rated the difficulty of those particular searches and the classifications were then averaged by difficulty using the same scale that was applied in the administrative survey. again, almost all levels of difficulties were reported for many classifications but that the overall average hiring difficulty rating was 1.9. to provide as accurate a picture as possible the surveys asked both groups to indicate if any well known mitigating factors contributed to complications with the job searches. these factors are shown in table 8 which stacks both groups for comparison. this particular dataset reveals some interesting patterns. those roles that were in the most demand were the also the most difficult to hire for, while these also were the easier positions for candidates to find. librarians also listed more job categories as having a significant technology component than the administrators had. perhaps most notable is the discrepancy shown between how administrators perceive the qualifications of candidates as compared to how candidates view themselves. while both groups acknowledge lack of it skills and qualifications as the number one mitigating factor, library administrators perceive the problem as being significantly more serious. this data backs up other recent findings that important new job categories are being defined in lis.30 the data also further support that these roles, while centering on core librarianship principles, have a different skill set.31 ■■ job readiness perspectives issues of job readiness for academic librarians need to be looked at from a number of different perspectives. job readiness can be understood in one way by a candidate and can be something different to an employer. job readiness is not only of critical concern at the beginning of a librarian’s career, clearly this attribute continues to be significant throughout an individual’s length of service in one or more roles and to one or more employers. job readiness is composed of several factors, the most important being education, experience and ongoing skill acquisition. while this is certainly true for all librarians it is of even more concern to those librarians with significant technology roles because of rapid changes in technology. a concern has been established in the literature and in this study that lis education, in the areas of technology, may be inadequate and lack the intensity necessary for modern libraries. this perception has been backed up by entrants to the profession.32 that technology skills are extremely important to library employers has been evident for at least a decade. in 2001 a case study on table 8. mitigating factors in hiring and job search (n = 93) administrative survey: mitigating factors in hiring as a percentage of respondents to the question (n = 93) % of responses we had difficulty getting an applicant pool with adequate skills 54 we are unable to offer qualified candidates what we feel is a competitive salary. 38 we are located in what may reasonably be perceived as an undesirable area to live. 23 we are located in an area with a very high cost of living. 23 we have an it infrastructure or environment that we and/or a candidate may have perceived as unacceptable. 20 the current economic climate has made hiring for these types of positions easier. 18 a successful candidate did not accept an offer of employment 13 librarian survey: mitigating factors in job search as a percentage of respondents to the question (n = 198) % of responses i suspect i may not have/had adequate skills, experience or i was otherwise unqualified. 25 i have not been able to find a position for what i consider to be a fair salary. 11 many jobs are located in what may reasonably be perceived as an undesirable area to live. 10 many jobs are located in an area with a very high cost of living. 15 some jobs have an it infrastructure or environment that i have perceived as unacceptable. 10 the current economic climate has now made finding these types of positions tougher. 22 i was a successful candidate but i could or did not accept an offer of employment. 3 136 information technology and libraries | september 2011 library technology experience they preferred from a candidate. there were 97 responses; the range of preferred experience was 0–7, the mean was 3.06, and the mode was 3. librarians were also asked how much experience they had in a technology-related library role. there were 187 responses; the range of experience was 0–39 years, the mean was 8.7, the mode was 5. when participating administrators were asked if they felt it was necessary to have an mlis librarian fill a technology-related role that is heavily user-centric, 110 administrators responded. also a very important factor, with one study of academic library search committees reporting committee members mentioning that “experience trumps education.”34 this study sought to gather data on possible patterns in the job readiness area. the authors wanted to know how job candidates and employers felt about the viability of new mls graduates, how experience factored into job readiness, how much experience is out there and how long term experience impacted expectations. the survey asked administrators how many years of table 9.

librarians and the value of related technology degrees. areas of agreement are noted in the importance of preprofessional experience, three or more years of experience, and the generally positive attitude regarding librarians’ ability to successfully take on significant technology roles in libraries. ■■ ongoing skill acquisition and retention how librarians with significant technology roles acquire the skills needed to do their jobs and how they keep those skills current was of great interest in this study. the importance of preprofessional experience has been noted but we should also include the value of service learning in lis education as an important starting point. successful service learning experiences include practicum and partnerships with libraries in need of technology-related services. successful projects such as online exhibits, wireless policies, taxonomy-creation and cross-walking for contentdm are just a few of the service projects that have given lis students real-world experience.35 this responses ranged from 50 percent “yes,” 38 percent “no,” and 12 percent “unsure.” to the same question, 195 practicing technology librarians responded with 58 percent “yes,” 23 percent “no,” and 20 percent “unsure.” the administrator participants were asked if they had ever had to fill a technology-related librarian role with a non-mls hire simply because they were unable to find a qualified librarian to fill the job. of 106 responses, 22 percent reported that they hired a non-mls candidate. the librarian participants were also was asked to report on mls status; out of 194 responses, 93 percent reported holding an mls or equivalent. the survey also asked the librarian participants to report what year they graduated from their mls program as the authors felt this data was important to the inherent longitudinal perspectives reported in the study. of 162 responses, participants reported graduating between 1972–2009. the mean was 1999, the median was 2002, and the mode was 2004. table 9 shows a question set related to experience factors, which stacks both groups for comparison. there are a few notable points in this particular dataset including what appears to be an area of disagreement between administrators and librarians about the table 10. education and skill supplementation for librarians with technology roles administrative survey: in what ways have you supplemented training for your librarians or professional staff with technology-related roles? (does not include ala conferences) % we have paid for technology-related conferences and pre-conferences. 79 we have paid for or allowed time off for classes. 72 we have paid for or allowed time for off online workshops and /or tutorials 87 we have paid for books or other learning materials. 55 we have paid for some or all of a 1st or 2nd graduate degree. 12 we would like to supplement but it is not in our budget. 5 we feel that keeping up with technology is essential for librarians with technology-related roles. 73 librarian survey: in what ways have you supplemented your own education related to technology skill development in terms of your time and/or money? (not including ala conferences) % i have attended technology-related conferences and pre-conferences. 73 i have taken classes. 60 i have taken online workshops and/or tutorials 87 i have bought books or other learning materials. 77 i am getting a 1st or 2nd graduate degree. 9 we would like to supplement my own education but i can not afford it. 13 i would like to supplement my own education but i do not have time. 13 i have not had to supplement in any way. 1 i feel that keeping up with technology is essential for librarians with technology-related roles. 84 i feel that keeping up with technology is somewhat futile. 11 138 information technology and libraries | september 2011 librarians who have transitioned successfully into technology centric roles. this supports the perception that experience and on the job learning play a leading role in the development of technology skills for librarians. openended survey comments also revealed a number of staff who initially were hired in an it role and then went on to acquire an mls while continuing in their technologyfocused role. retention is sometimes problematic for librarians with it roles, primarily because many of them are also employable in many other settings apart from libraries. the survey asked administrators “do you know any librarians with technology roles that have taken it positions outside the library field?” and out of 111 respondents, 33 percent answered “yes.” in open-ended responses the most common reasons administrators felt retention may be a problem was salary, lack of challenges/opportunities, and risk averse cultures. the survey also asked the librarian group “do you think you would ever consider taking an it position outside the library field?” out of 190 respondents; 34 percent answered “yes,” 23 percent “yes, but only if it was education related,” and 42 percent “no.” additionally 38 percent of these librarian respondents knew a librarian who took an it position outside the library field. for the librarian participants an open response field in the survey, named work environment and lack of support for technology as the most often named reasons for this leaving a position. the surveys used in this research study covered several complicated issues. those who responded to the surveys were encouraged to leave open text comments research study asked administrators and librarians in what formal ways they supplement their ongoing education and skill acquisition. table 10 shows these results in a stacked format for comparison. also of interest in this data set is the higher level of importance librarians place on continuing skill development in the area of technology. in open ended text responses a number of librarians reported that the less formal methods of monitoring electronic discussion lists and articles was also a very important part of keeping up with technology in their area. the priority of staying educated, active and current for librarians with significant technology roles cannot be underestimated; what tennant defines as technology agility, the capacity to learn constantly and quickly. i cannot make this point strongly enough. it does not matter what they know now. can they assess a new technology and what it may do (or not do) for your library? can they stay up to date? can they learn a new technology without formal training? if they can’t they will find it difficult to do the job.36 not all librarians with technology roles start out in those positions and thus role transformation must be examined. in some cases librarians with more traditional roles such as reference and collection development have transformed their skill set and taken on technology centric roles. table 11 shows the results of the survey questions related to role transformation in a stacked format for comparison. to be noted in this data set is the large number of table 11. role transformation from traditional library roles to technology centric roles and the reverse. administrative survey (n = 104) % we have had one or more librarians make this transformation successfully. 53 we have had one or more librarians attempt this transformation with some success. 35 we have had one or more librarians attempt this transformation without success. 17 some have been interested in doing this but have not done so. 14 we do not seem to have had anyone interested in this 11 we have had one or more librarians who started out in a technology-related librarian role but have left it for a more traditional librarian role. 5 librarian survey (n = 184) % i

to make a technology role transformation but with only some success. 12 i have made a technology role transformation but sometimes i wish i had not. 9 i have made a technology role transformation but i wish i had not and i am interested in returning to a more traditional librarian role. 9 i am not a librarian. 4 librarians and technology skill acquisition: issues and perspectives | riley-huff and rholes 139 vary considerably from program to program and the content of individual courses appears to vary considerably as well. there appears to be a clear need for additional courses at a more advanced level. this need is evidenced by the experiences of both information technology job candidates and the administrators involved in the hiring decisions. there are clearly still difficulties in both the acquisition of needed skill sets for certain positions and in actual hiring for some information technology positions. there are also some discrepancies between how administrators perceive candidates’ qualifications as compared to how the candidates view themselves. administrators perceive the problem of a lack of it skills/qualifications as more serious than do candidates. the two groups also differ on the question of “readiness” of new professionals. the two groups do agree on the importance of preprofessional experience, and they both exhibit generally positive attitudes toward librarians’ ability to successfully take on significant technology roles in libraries. in several key areas. a large number of comments were received and many of them were of considerable length. many individuals clearly wanted to be heard, others were concerned their story would not be captured in the data, and many expressed a genuine overall interest in the topic. a few salient comments from a variety of areas covered are given in table 12. ■■ conclusion this study seeks to provide an overview of the current issues related to it staffing in academic libraries by reporting on three areas dealing with library skill acquisition and employment. with regards to the status of technology course offerings in lis programs, there has been a significant increase in the number of technologyrelated courses, but the numbers of technology courses table 12. a sample of open ended responses from the two surveys administrative survey “there is a huge need for more and adequate technology training for librarians. it is essential for libraries to remain viable in the future.” “only one library technology position (coordinator) is a professional librarian. others are professional positions without mls.” “there is a lot of competition for few jobs, especially in the current economic climate.” “we finally hired at the level of technician as none of the mls candidates had the necessary qualifications.” “if i wanted a position that would develop strategy for the library’s tools on the web or create a digitization program for special collections, i probably would want an mls with library experience simply because they understand the expectations and the environment.” “number of years of experience in technology is not as important as a willingness to learn and keep current. sometimes old dogs won’t move on to new tricks. sometimes new dogs aren’t interested in learning tricks.” librarian survey “i believe that because technology is constantly changing and evolving, librarians in technology-oriented positions must do the same.” “my problem with being a systems librarian in a small institution is that the job was 24/7/365. way too much stress with no down time.” “i have left the library field for a few years but came back. my motivation was a higher salary, but that didn’t really happen.” “i’m considering leaving my current position because the technology role (which i do love) was added to my position without much training or support. now that part of my job is growing so that i can’t keep up with all my duties.” “i don’t think that library school alone prepared me for my job. i had to do a lot of external study and work to learn what i did, and worked as a part-time systems library assistant while in school, where i learned the majority of what prepared me for my current job.” “library schools need to be more rigorous about teaching students how to innovate with technology, not just use tools others have built. you can’t convert “traditional” librarians into technology roles without rigorous study. otherwise, you will get mediocre and even dangerous results.” 140 information technology and libraries |

much can be taught in lis courses or practicum, and how much must be expected through on-the-job experience are good areas for more research. references 1. james michalko, constance malpas and arnold

director: ohio college library center, columbus, ohio a test of validity of earlier findings on 3,3 search-ke y retrieval from an in-process file for retrieval from a marc file. probability of number of entries retrieved per reply is essentially the same for both files. this study was undertaken to test the applicability of previous findings on retrieval of name-title entries from a technical processing system fil e ( 1 ) to retrieval from a marc file; the technique for retrieval employs truncated 3,3 search keys. materials and methods the study cited above employed a file of 132,808 name-title entries obtained from the yale university library's machine aided technical processing system. bibliographic control was not maintained for the generation of records in this file , with the result that the file contained errors that simulated errors in the requests library users put to catalogs. the marc file employed in the present study contains 121,588 name-title entries that are nearly error free. whereas the marc file possesses few records bearing foreign titles, the yale file has a significantly higher percentage of such titles, as would be expected for a large university library. initial articles were deleted in yale titles, but only english articles in marc titles because the language of foreign language titles is not identified in marc. 212 journal of library automation vol. 4/4 december, 1971 design of the program used to analyze the marc file was the same as that for the program employed in the previous study. however, the new program runs on a xerox data systems sigma 5 computer. the test employed the 3,3 search key to make possible comparison with previous results. results table 1 presents the percentage of time that up to five replies can be expected, assuming equal likelihood of key choice. inspection of the table reveals that there is no significant difference between the findings from the yale and the marc files. table 1. probability of number of entries per reply using 3,3, search key number of replies 1 2 3 4 5 discussion cumulative probability percentage yale file marc file 78.58 79.98 92.75 93.28 96.83 96.93 98.40 98.26 99.08 98.91 the same result was expected for the marc file that had been obtained earlier from the yale file. possible influences that might have led to different results were the existence of errors in the yale file, a significant proportion of foreign titles in the yale file as compared to the nearly all-english marc file, and the inability to mechanically delete the initial articles in the few foreign language marc titles. it is most unlikely that the effects of these differences are masking one another. conclusion the findings of a previous study on the effectiveness of retrieval of entries from a large bibliographic file ( 1) by use of a truncated 3,3 search key have been confirmed for a similarly large marc file. reference 1. kilgour, frederick g.; long, philip l. ; leiderman, eugene b.:

first place on my personal list of words i would prefer never to need to use again, let alone hear used, i find it eminently satisfying that some activities and events from before covid continue in their usual, predictable ways. for me, the quarterly rhythm of publication of information technology and libraries is one of those activities. it is helping keep me grounded. while it is certainly not much in the scope of what is happening all around me, it is at least something. one thing that is changing is that this journal, along with library resources and technical services and library leadership & management are now publications of ala’s newest division: core: leadership, infrastructure, futures. you’ll notice a new logo at the top of our site, reflecting the new organizational structure. i am excited about the possibilities of richer cross-core cooperation and collaboration as we explore our new structure. this issue includes the first—and last—lita president’s message from incoming and outgoing lita president evviva weinraub lajoie. evviva assumed the lita presidency this summer, just before the merger of lita, llama, and alcts into the new core division took place on september 1. members of those three merged divisions should watch for information about elections for the new core president in october. i am pleased that this issue includes the 2020 lita/ex libris student writing award winning article, evaluating the impact of the long-s upon 18th-century encyclopedia britannica automatic subject metadata generation results, by sam grabus of drexel university. julia bauder, the chair of this year’s selection committee (i was also a member, as ital editor) said, “this valuable work of original research helps to quantify the scope of a problem that is of interest not only in the field of library and information science, but that also, as grabus notes in her conclusion, could affect research in fields from the digital humanities to the sciences.” before closing, i would like to express my appreciation to breanne kirsch, who ably served on the editorial board from 2018-2020. sincerely, kenneth j. varnum, editor varnum@umich.edu september 2020

 language  processing  (bnlp)  tools.  researchers  attempted  to  obtain  content   directly  from  pubmed  central  (pmc).  this  attempt  failed  because  of  limits  on  use  of  content  in  pmc.   next,  researchers  and  their  library  liaison  attempted  to  obtain  content  from  contacts  in  the  technical   divisions  of  the  publishing  industry.  this  resulted  in  an  incomplete  research  data  set.  researchers,  the   library  liaison,  and  the  acquisitions  librarian  then  collaborated  with  the  sales  and  technical  staff  of  a   major  science,  technology,  engineering,  and  medical  (stem)  publisher  to  successfully  create  a   method  for  obtaining  xml  content  as  an  extension  of  the  library’s  typical  acquisition  process  for   electronic  resources.  our  experience  led  us  to  realize  that  text-­‐mining  rights  of  full-­‐text  articles  in   xml  format  should  routinely  be  included  in  the  negotiation  of  the  library’s  licenses.   introduction   the  university  of  colorado  anschutz  medical  campus  (cu  anschutz)  is  the  only  academic  health   sciences  center  in  colorado  and  the  largest  in  the  region.  annually,  cu  anschutz  educates  3,480   full-­‐time  students,  provides  care  during  1.5  million  patient  visits,  and  receives  more  than  $400   million  in  research

(also  known  as  nlp  or,  more  colloquially,  “text  mining”)  is  the  development  and  application  of   computer  programs  that  accept  human  language,  usually  in  the  form  of

  functionality,  such  as  information  retrieval  or  information  extraction.  cu  anschutz’s  health   sciences  library  (hsl)  supports  hunter’s  research  group  by  providing  a  reference  and  instruction   librarian,  lynne  fox,  to  participate  on  the  research  team.  hunter’s  group  is  working  on   computational  methods  for  knowledge-­‐based  analysis  of  genome-­‐scale  data.2  as  part  of  that  work,   his  group  is  devising  and  implementing  text-­‐mining  methods  that  extract  relevant  information   from  biomedical  journal  articles,  which  is  then  integrated  with  information  from  gene-­‐centric   databases  and  used  to  produce  a  visual  representation  of  all  of  the  published  knowledge  relevant   to  a  particular  data  set,  with  the  goal  of  identifying  new  explanatory  hypotheses.     hunter’s  research  group  demonstrated  the  potential  of  integrating  data  and  research  information   in  a  visualization  to  further  new  discoveries  with  the  “hanalyzer”   (http://hanalyzer.sourceforge.net).  their  test  case  used  expression  data  from  mice  related  to   craniofacial  development  and  connected  that  data  to  pubmed  abstracts  using  gene  or  protein   names.  “copying  of  content  that  is  subject  to  copyright  requires  the  clearing  of  rights  and   permissions  to  do  this.  for  these  reasons  the  body  of  text  that  is  most  often  used  by  researchers   for  text  mining  is  pubmed.”3  the  resulting  visualization  allowed  researchers  to  identify  four  genes   involved  in  mouse  craniofacial  development  that  had  not  previously  been  connected  to  tongue   development,  with  the  resulting  hypotheses  validated  by  subsequent  laboratory  experiment.4  the   knowledge-­‐based  analysis  tool  is  open  access.     to  continue  the  development  of  the  bnlp  tools  for  the  knowledge-­‐based  analysis  system,  three   things  were  required:  a  large  collection  of  full-­‐text  journal  articles  in  xml  format,  the  right  to  text   mine  the  collection,  and  the  right  to  store  and  use  the  collection  and  the  data  mined  from  it  for   grant-­‐funded  research.  the  larger  the  dataset,  the  more  robust  the  visual  representations  of  the   knowledge-­‐based  analysis  system,  so  hunter’s  research  group  sought  to  compile  a  large  corpus  of   relevant  literature,  beginning  with  journal  articles.  the  text  that  is  mined  can  start  in  many   formats;  however,  xml  provides  a  computer-­‐ready  format  for  text  mining  because  it  is  structured   to  indicate  parts  of  the  document.  xml  is  “called  a  ‘markup  language’  because  it  uses  tags  to  mark   and  delineate  pieces  of  data.  the  ‘extensible’  part  means  that  the  tags  are  not  pre-­‐defined;  users   can  define  them  based  on  the  type  of  content  they  are  working  with.”5,6   xml  has  been  adopted  as  a  standard  for  content  creation  by  journal  publishers  because  it   provides  a  flexible  format  for  electronic  media.7  xml  allows  the  parts  of  a  journal  article  to  be   encoded  with  tags  that  identify  the  title,  author,  abstract,  and  other  sections,  allowing  the  article  to   be  transmitted  electronically  between  editor  and  publisher  and  to  be  easily  formatted  and   reproduced  into  different  versions  (e.g.,  print,  online).  xml  can  also  indicate  significant  content  in   the  text,  such  as  biological  terms  or  concepts.  xml  allowed  hunter’s  research  group  to  write   computer  programs  that  can  make  sense  of  each  article  by  using  the  xml  tags  as  indicators  of   content  and  placement  within  the  article.  products  have  been  developed,  such  as  la-­‐pdftext,  to   extract  text  from  pdf  documents.8  however,  direct  access  to  xml  provides  more  useful  corpora     information  technology  and  libraries  |  september  2014   7   because  the  document  markup  saves  time  and  improves  the  accuracy  of  results  extracted  from   xml.     once  the  sections  and  content  of  an  article  are  identified,  text-­‐mining  techniques  are  applied  to  the   article.  “text  mining  extracts  meaning  from  text  in  the  form  of  concepts,  the  relationships  between   the  concepts  or  the  actions  performed  on  them  and  presents  them  as  facts  or  assertions.”9  text-­‐ mining  techniques  can  be  applied  to  any  type  of  information  available  in  machine-­‐readable  format   (e.g.,  journal  article,  e-­‐books).  a  dataset  is  created  when  the  text-­‐mined  data  is  aggregated.  using   bnlp  tools,  hunter’s  research  group’s  knowledge-­‐based  analysis  system  analyzed  the  dataset  and   produced  visual  representations  of  the  knowledge  that  have  the  potential  to  lead  to  new   hypotheses.  text  mining  and  bnlp  techniques  have  the  potential  to  build  relationships  between   the  knowledge  contained  in  the  scholarly  literature  that  lead  to  new  hypothesis  resulting  in  more   rapid  advances  in  science.   literature  review   hunter  and  cohen  explored  “literature  overload”  and  its  profoundly  negative  impact  on  discovery   and  innovation.10  with  an  estimated  growth  rate  of  3.1  percent  annually  for  pubmed  central,  the   us  national  library  of  medicine’s  repository,  researchers  struggle  to  master  the  new  literature  of   their  field  using  traditional  methods.  yet  much  of  the  advancement  of  biological  knowledge  relies   on  the  interplay  of  data  created  by  protein,  sequence,  and  expression  studies  and  the   communication  of  information  and  discoveries  through  nontextual  and  textual  databases  and   published  reports.11  how  do  biomedical  researchers  capitalize  on  and  integrate  the  wealth  of   information  available  in  the  scholarly  literature?  “the  common  ground  in  the  area  of  content   mining  is  in  the  shared  conviction  that  the  ever  increasing  overload  of  information  poses  an   absolute  need  for  better  and  faster  analysis  of  large  volumes  of  content  corpora,  preferably  by   machines.”12   bnlp  “encompasses  the  many  computational  tools  and  methods  that  take  human-­‐generated  texts   as  input,  generally  applied  to  tasks  such  as  information  retrieval,  document  classification,   information  extraction,  plagiarism  detection,  or  literature-­‐based  discovery.”13  bnlp  techniques   accomplish  many  tasks  usually  performed  manually  by  researchers,  including  enhancing  access   through  expanded  indexing  of  content  or  linkage  to  additional  information,  automating  reviews  of   the  literature,  discovering  new  insights,  and  extracting  meaning  from  text.14  text  mining  is  just   one  tool  in  a  larger  bnlp  toolbox  of  resources  used  to  read,  reason,  and  report  findings  in  a  way   that  connects  data  to  information  sources  to  speed  discovery  of  new  knowledge.15  according  to   pioneering  text-­‐mining  researcher  marti  hearst,  “text  mining  is  the  discovery  by  computer  of  new,   previously  unknown  information,  by  automatically  extracting  information  from  different  written   resources.  a  key  element  is  the  linking  together  of  the  extracted  information  together  to  form  new   facts  or  new  hypotheses  to  be  explored  further  by  more  conventional  means  of     negotiating  a  text  mining  license  for  faculty  researchers  |  williams  et  al   8   experimentation.”16  biomedical  text  mining  uses  “automated  methods  for  exploiting  the  enormous   amount  of  knowledge  available  in  the  biomedical  literature.”17   recent  reports,  commissioned  by  private  and  governmental  interest  groups,  discuss  the  economic   and  societal  value  of  text  mining.18,19  the  mckinsey  global  institute  estimates  the  worth  of   harnessing  big  data  insights  in  us  health  care  at  $300  billion.  the  report  concludes  that  greater   sharing  of  data  for  text  mining  enables  “experimentation  to  discover  needs,  expose  variability,  and   improve  performance”  and  enhances  “replacing/supporting  human  decision  making  with   automated  algorithms,”  among  other  benefits.  furthermore,  the  mckinsey  report  points  out  that   north  america  and  europe  have  the  greatest  potential  to  take  advantage  of  innovation  because  of   a  well-­‐developed  infrastructure  and  large  stores  of  text  and  data  to  be  mined.20  however,  these   new  and  evolving  technologies  are  challenging  the  current  intellectual-­‐property  framework  as   noted  in  an  independent  report  by  ian  hargreaves,  “digital  opportunity:  a  review  of  intellectual   property  and  growth,”  resulting  in  lost  opportunity  for  innovation  and  economic  growth.21  in  “the   value  and  benefits  of  text  mining,”  jisc  finds  copyright  restrictions  limit  access  to  content  for  text   mining  in  the  biomedical  sciences  and  chemistry  and  that  costs  for  access  and  infrastructure   prevent  entry  into  text-­‐mining  research  for  many  noncommercial  organizations.22  despite   copyright  barriers,  organizations  surveyed  pointed  out  the  risks  associated  with  failing  to  use  text-­‐ mining  techniques  to  further  research  include  financial  loss,  loss  of  prestige,  opportunity  lost,  and   the  brain  drain  of  having  talented  staff  seek  more  fulfilling  work.  jisc  explores  a  research  project’s   workflow  and  finds  a  lack  of  access  to  text  mining  delayed  the  publication  of  an  important  medical   research  study  by  many  months,  or  the  time  the  research  team  spent  analyzing  and  summarizing   relevant  research.23  both  reports  advocate  an  exception  to  intellectual  property  rights  for   noncommercial  text-­‐mining  research  to  balance  the  protection  of  intellectual  property  with  the   access  needs  of  researchers.  a  centrally  maintained  repository  for  text  mining  has  been  proposed,   although  its  creation  would  face  significant  challenges.24   scholarly  journal  content  is  the  raw  “ore”  for  text  mining  and  bnlp.  the  lack  of  access  to  this  ore   creates  a  bottleneck  for  researchers.  “new  business  models  for  supporting  text  mining  within  the   scholarly  publishing  community  are  being  explored;  however,  evidence  suggests  that  in  some   cases  lack  of  understanding  of  the  potential  is  hampering  innovation.”25  bnlp  and  machine-­‐ learning  research  products  are  more  accurate  and  complete  when  more  content  is  available  for   text  mining.  “knowledge  discovery  is  the  search  for  hidden  information.  .  .  .  hence  the  need  is  to   start  looking  as  widely  as  possible  in  the  largest  set  of  content  sources  possible.”26  however,  as   noted  in  a  nature  article,  “the  question  is  how  to  make  progress  today  when  much  research  lies   behind  subscription  firewalls  and  even  ‘open’  content  does  not  always  come  with  a  text-­‐mining   license.”27  large  scientific  publishers  are  facing  economic  challenges,  and  potentially  diminished   economic  returns,  as  the  tension  over  the  right  to  use  licensed  content  heats  up.  nature,  the   flagship  of  a  major  scientific  publisher,  predicted  “trouble  at  the  text  mine”  if  researchers  lack   access  to  the  contents  of  research  publications.28  and  a  2012  investment  report  predicted  slower     information  technology  and  libraries  |  september  2014   9   earnings  growth  for  elsevier,  the  largest  stem  publisher,  if  it  blocked  access  to  licensed  content   by  text-­‐mining  researchers.  the  review  predicted,  “if  the  academic  community  were  to  conclude   that  the  commercial  terms  imposed  by  elsevier  are  also  hindering  the  progress  of  science  or  their   ability  to  efficiently  perform  research,  the  risk  of  a  further  escalation  of  the  acrimony  [between   elsevier  and  the  academic  community]  rises  substantially.”29  with  open  access  alternatives   proliferating,  including  making  federally  funded  research  freely  accessible,  stem  publishers  are   under  increased  pressure  to  respond  to  market  forces.  “the  greatest  challenge  for  publishers  is  to   create  an  infrastructure  that  makes  their  content  more  machine-­‐accessible  and  that  also  supports   all  that  text-­‐miners  or  computational  linguists  might  want  to  do  with  the  content.”30  on  the  other   end  of  the  spectrum,  researchers  are  struggling  to  gain  legal  access  to  as  much  content  as  possible.     academic  libraries  have  long  excelled  at  serving  as  the  bridge  between  researchers  and  publishers   and  can  expand  their  roles  to  include  navigating  the  uncharted  territory  of  obtaining  text-­‐mining   rights  for  content.  increasing  the  library’s  role  in  text  mining  and  other  associated  bnlp  and   machine-­‐learning  methods  offers  tremendous  potential  for  greater  institutional  relevance  and   service  to  researchers.31  at  cu  anschutz’s  hsl,  fox  and  williams,  an  acquisitions  librarian,  found   natural  opportunities  for  collaboration  including  negotiating  rights  to  content  more  efficiently   through  expanded  licensing  arrangements  and  facilitating  the  secure  transfer  and  storage  of  data   to  protect  researchers  and  publishers.   method   hunter  and  fox  began  working  in  2011  to  obtain  a  large  corpus  of  biomedical  journal  articles  in   xml  format  to  create  a  body  of  text  as  comprehensive  as  possible  for  bnlp  experimentation  that   would  further  advance  hunter’s  research  group’s  knowledge-­‐based  analysis  system.  the  desired   result  was  an  aggregated  collection  obtained  from  multiple  publishers,  stored  locally,  and   available  on  demand  for  the  knowledge-­‐based  analysis  system  to  process.  hunter  and  fox  soon   realized  that  “the  process  of  obtaining  or  granting  permissions  for  text  mining  is  daunting  for   researchers  and  publishers  alike.  researchers  must  identify  the  publishers  and  discover  the   method  of  obtaining  permission  for  each  publisher.  most  publishers  currently  consider  mining   requests  on  a  case  by  case  basis.”32  they  pursued  a  multifaceted  strategy  to  build  a  robust   collection  and  to  determine  which  strategy  proved  most  fruitful  because,  during  a  grant  review,   national  library  of  medicine  staff  wanted  evidence  of  access  to  an  xml  collection  before  awarding   a  grant.     fox  first  approached  two  open-­‐access  publishers,  biomed  central  (bmc)  and  public  library  of   science  (plos),  to  request  access  to  xml  text  from  journals  in  the  subjects  of  life  and  biomedical   science.  fox  had  existing  contacts  within  both  organizations  and  an  agreement  was  reached  to   obtain  xml  journal  articles.  letters  of  understanding  were  quickly  obtained  as  both  publishers   were  excited  about  exploring  new  ways  for  their  research  publications  to  be  accessed  and  the   potential  to  increase  the  use  of  their  journals.  possible  journal  titles  were  identified  and     negotiating  a  text  mining  license  for  faculty  researchers  |  williams  et  al   10   arrangements  were  made  to  transfer  and  store  files  locally  from  bmc  and  plos  to  hunter’s   research  group.   hunter  approached  staff  at  pubmedcentral  (pmc)  to  request  access  to  articles  and  discovered   they  could  only  be  made  available  with  permission  from  publishers.  a  wiley  research  and  product   development  executive  granted  hunter  permission  to  access  wiley  articles  in  pmc.  the  wiley   executive  was  interested  in  learning  what  impact  text  mining  might  have  on  wiley  products.   hunter’s  research  group  planned  to  transfer  document  type  definition  (dtd)  format  files  from   pmc.  unfortunately,  when  hunter’s  research  group  staff  requested  file-­‐transfer  assistance  from   pmc,  no  pmc  staff  were  available  to  provide  the  technical  help  needed  because  of  budget   reductions.  pmc  staff  could  accurately  evaluate  their  time  commitment  because  they  had  a  clear   understanding  of  the  xml  access  and  transfer  process,  and  knew  they  could  not  allocate  resources   to  the  effort.     hunter  then  began  to  leverage  his  professional  network  connections  to  obtain  content  from  a   major  stem  vendor.  research  and  development  division  directors  within  the  company  were   familiar  with  the  work  of  hunter’s  research  group  and  were  willing  to  provide  assistance  in   acquiring  content.  however,  when  the  research  group  began  to  perform  research  using  this  data,   further  investigation  determined  that  the  contents  were  not  adequate  for  the  research.  follow-­‐up   between  fox,  the  research  group,  and  the  vendor  revealed  that  the  group’s  needs  were  not   communicated  in  the  vendor’s  vernacular,  resulting  in  the  group  not  clearly  understanding  what   content  the  vendor  was  providing.  this  disconnect  occurred  in  the  communication  flow  from  the   research  group  to  the  vendor’s  research  and  development  staff  to  the  vendor’s  sales  staff  (who   identified  the  content  to  be  shared).  it  was  a  like  a  game  of  telephone  tag.   after  the  initial  strategies  produced  mixed  results,  hunter’s  research  group  hypothesized  that  they   could  harvest  materials  through  hsl’s  journal  subscriptions.  hunter’s  research  group  attempted   to  crawl  and  download  journal  content  being  provided  by  hsl’s  subscription  to  a  major  chemistry   publisher.  since  publishers  monitor  for  web  crawling  of  their  content,  the  chemistry  publisher   became  aware  of  the  unusual  download  activity,  turned  off  campus  access,  and  notified  the  library   that  there  may  have  been  an  unauthorized  attempt  to  access  the  publisher’s  content.  researchers   are  often  unaware  of  complex  copyright  and  license  compliance  requirements.  in  fact,  librarians   sometimes  become  aware  of  text-­‐mining  projects  only  after  automated  downloads  of  licensed   content  prompt  vendors  to  shut  off  campus  access.33  libraries  can  prevent  interruption  of   campus-­‐wide  access  to  important  resources  by  suggesting  more  effective  content-­‐access  methods.     williams,  an  hsl  acquisitions  librarian,  investigated  the  interruption  in  access  and  discovered   hunter’s  research  group’s  efforts  to  obtain  journal  articles  to  text  mine  for  their  research.  she   offered  to  use  her  expertise  in  acquiring  content  to  help  hunter’s  research  group  obtain  the   dataset  needed  for  their  research.  initially,  hunter  and  fox  had  not  included  an  acquisitions     information  technology  and  libraries  |  september  2014   11   librarian  because  that  position  was  vacant.  after  williams  became  involved,  the  effort  focused  on   licensing  content  via  negotiation  and  licensing  with  individual  publishers.   results   “there  are  a  large  number  of  resources  to  help  the  researcher  who  is  interested  in  doing  text   mining”  but  “no  similar  guide  to  obtaining  the  necessary  rights  and  permissions  for  the  content   that  is  needed.”34  at  cu  anschutz,  this  vacuum  was  filled  by  williams,  who  is  knowledgeable  about   the  acquisition  of  content,  and  fox,  who  is  knowledgeable  about  hunter’s  research,  serving  as  the   bridge  between  the  research  group  and  the  stem  publisher.  by  working  together  and  capitalizing   on  each  other’s  expertise,  williams  and  fox  were  able  to  facilitate  the  collaboration  that  developed   a  framework  for  purchasing  a  large  collection  of  full-­‐text  journal  articles  in  xml  format.  as  the   collaboration  progressed,  three  major  elements  to  the  framework  surfaced,  including  a  pricing   model,  a  license  agreement,  and  the  dataset  and  delivery  mechanism.   researchers  interested  in  legally  text  mining  journal  content  often  find  themselves  having  to   execute  a  license  agreement  and  pay  a  fee.35  what  should  the  fee  be  based  on  to  create  a  fair  and   equitable  pricing  model?  publishers  establish  pricing  for  library  clients  on  the  basis  of  not  only  the   content,  but  many  valued-­‐added  services  such  as  the  breath  of  titles  aggregated  and  made   available  for  purchase  in  a  single  product,  the  creation  of  a  platform  to  access  the  journal  titles,  the   indexing  and  searching  functionality  within  the  platform,  and  the  production  of  easily  readable   pdf  versions  of  articles.  these  value-­‐added  services  are  not  required  for  text-­‐mining  endeavors.   rather,  the  product  is  the  raw  journal  content  that  has  been  peer-­‐reviewed,  edited,  and  formatted   in  xml  that  precedes  the  addition  of  value-­‐added  services.  therefore  the  pricing  should  not  be   equivalent  to  the  cost  of  a  library’s  subscription  to  a  journal  or  package  of  journals.  in  the  end,   after  lengthy  negotiations,  the  pricing  model  for  the  hunter’s  research  group  collection  of  full-­‐text   journal  articles  in  xml  format  consisted  of   • a  cost  per  article;   • a  minimum  purchase  of  400,000  articles  for  one  sum  on  the  basis  of  the  cost  per  article;   • an  annual  subscription  for  the  minimum  purchase  of  400,000;   • the  ability  to  subscribe  to  additional  articles  in  excess  of  400,000  in  quantities  determined   by  hunter’s  research  group;   • a  volume  discount  off  the  per  article  price  for  every  article  purchased  in  excess  of  400,000;   • inclusion  of  the  core  journal  titles  purchased  via  the  library’s  subscription  at  no  charge;     • inclusion  of  the  core  journal  titles  purchased  by  the  university  of  colorado  boulder  at  no   charge  because  of  hunter’s  joint  appointment  at  both  cu  boulder  and  cuanschutz   campuses;  and   • a  requirement  for  hsl  to  maintain  its  subscription  to  the  vendor’s  product  at  its  current   level.     negotiating  a  text  mining  license  for  faculty  researchers  |  williams  et  al   12   “where  institutions  already  have  existing  contracts  to  access  particular  academic  publications,  it  is   often  unclear  whether  text  mining  is  a  permissible  use.”36  from  the  beginning,  common  ground   was  easily  found  on  the  subject  of  core  titles  purchased  by  the  two  campuses’  libraries.  core  titles   are  typically  those  journals  that  libraries  pay  a  premium  for  to  obtain  perpetual  rights  to  the   content.  most  of  the  negotiation  focused  on  access  titles,  which  are  journals  that  libraries  pay  a   nominal  fee  to  have  access  to  without  any  perpetual  rights  included.   the  final  challenge  related  to  cost  was  determining  how  to  process  and  pay  for  the  product.   hunter’s  research  group  operates  on  major  grant  funding  from  federal  government  agencies.  the   university  of  colorado  requires  additional  levels  of  internal  controls  and  approvals  to  expend   grant  funds  as  well  as  to  track  expenditures  to  meet  reporting  requirements  of  the  funding   agencies.  also,  grant  funding  of  this  type  often  spans  multiple  fiscal  years  whereas  the  library’s   budget  operates  on  a  single  fiscal  year  at  a  time.  therefore  it  was  decided  that  hunter  would   handle  payment  directly  rather  than  transferring  funds  to  hsl  to  make  payment  on  their  behalf.   “libraries  as  the  licensee  of  publishers’  content  are  from  that  perspective  interested  in  the  legal   framework  around  content  mining.”37  during  price  negotiations,  williams  recommended   negotiating  a  license  agreement  similar  to  those  libraries  and  publishers  execute  for  the  purchases   of  journal  packages.  a  license  agreement  would  offer  a  level  of  protection  for  all  parties  involved   while  clearly  outlining  the  parameters  of  the  transaction.  hunter  and  the  stem  publisher  readily   agreed.     the  final  license  agreement  contained  ten  sections  including  definitions;  subscription;  obligations;   use  of  names;  financial  arrangement;  term;  proprietary  rights;  warranty,  indemnity,  disclaimer,   and  limitation  of  liability;  and  miscellaneous.  while  the  license  agreement  was  similar  to   traditional  license  agreements  between  libraries  and  publishers  for  journal  subscriptions,  there   were  some  notable  differences.  first,  in  the  definitions  section,  users  were  defined  and  limited  to   hunter  and  his  research  team.  this  limited  the  users  to  a  specific  group  of  individuals  unlike   typical  library–publisher  license  agreements  that  license  content  for  the  entire  campus.     second,  the  subscription  section  covered  how  the  data  can  be  used  in  detail  and  allowed  the   dataset  to  be  installed  locally.  this  was  important  to  make  the  dataset  available  on  demand  to   researchers;  to  allow  researchers  to  manipulate,  segment,  and  store  the  data  in  multiple  ways   instead  of  as  one  large  dataset;  and  to  allow  the  researchers  the  ability  to  access  and  use  the  large   dataset  efficiently  and  quickly.  because  the  dataset  would  be  manipulated  so  extensively,  the   license  gave  permission  to  create  a  backup  copy  and  store  it  separately.  the  subscription  section   also  required  the  dissemination  of  the  research  results  to  occur  in  such  a  way  that  the  dataset   could  not  be  extracted  and  used  by  others.  this  was  significant  because  prof.  hunter  releases  the   bnlp  software  applications  they  develop  as  open  source  software  so  that  the  applications  can  be   open  to  peer  review  and  attempts  at  reproduction.  ideally,  someone  could  download  the  open   source  software,  obtain  the  same  corpus  as  input,  and  see  the  same  output  mentioned  in  the  paper.     information  technology  and  libraries  |  september  2014   13   third,  the  obligations  section  was  radically  different  from  traditional  library–publisher  license   agreements  because  even  though  “publishers  are  still  working  out  how  to  take  advantage  of  text   mining  .  .  .  none  wants  to  miss  out  on  the  potential  commercial  value.”38  this  interest  prompted   the  crafting  of  an  atypical  obligations  section  in  the  license  agreement  that  included  an  option  for   hunter  to  collaborate  with  the  stem  publisher  to  develop  and  showcase  an  application  on  the   vendor’s  website  and  included  a  commitment  for  hunter  to  meet  quarterly  with  the  vendor’s   representatives  to  discuss  advances  in  research.  furthermore,  the  obligations  section  specified  a   request  for  hunter  and  the  university  of  colorado  to  recognize  the  vendor  where  appropriate  and   a  right  for  the  stem  publisher  to  use  any  research  software  application  released  as  open  source.   up  to  this  point,  williams  had  been  collaborating  with  the  university  of  colorado  in-­‐house  counsel   to  review  and  revise  the  license  agreement.  when  the  stem  publisher  requested  the  right  to  use   the  software  application,  williams  was  required  to  submit  the  license  agreement  to  the  university   of  colorado‘s  technology  transfer  office  for  review  and  approval.  approval  was  prompt  in  coming,   primarily  because  prof.  hunter  releases  his  software  applications  as  open  source.   fourth,  the  license  agreement  included  a  “use  of  names”  section,  which  is  not  found  in  typical   library–publisher  agreements.  this  section  authorized  the  vendor  to  use  factual  information   drawn  from  a  case  study  in  market-­‐facing  materials  and  a  requirement  that  the  vendor  request   written  consent,  as  required  from  the  university  of  colorado  system,  for  information  in  the  case   study  to  be  released  for  market  facing  materials.  the  vendor  also  agreed  not  to  use  the  university   of  colorado’s  trademark,  service  mark,  trade  name,  copyright,  or  symbol  without  prior  written   consent  and  to  use  these  items  in  accordance  with  the  university  of  colorado  system’s  usage   guidelines.     fifth,  the  vendor  agreed  not  to  represent  in  any  way  that  the  university  of  colorado  or  its   employees  endorse  the  vendor’s  products  or  services.  this  is  extremely  important  because  the   university  of  colorado’s  controller  does  not  allow  product  endorsements  because  of  the  federal   unrelated  business  income  tax.  exempt  organizations  are  required  to  pay  this  tax  if  engaged  in   activities  that  are  regularly  occurring  business  activities  that  do  not  further  the  purpose  of  the   exempt  organization.39     finally,  the  license  agreement  stated  all  items  would  be  provided  in  xml  format  with  a  unique   digital  object  identifier  (doi)  number,  essential  for  linking  xml  content  to  real-­‐world  documents   that  researchers  using  hunter’s  research  group’s  knowledge-­‐based  analysis  system  would  want  to   access.   after  a  pricing  model  and  license  agreement  were  finalized,  the  focus  turned  to  the  last  major   element  of  the  framework:  the  dataset  and  delivery  mechanism.  elements  such  as  quality  of  the   corpora  contents,  file  transfer  time,  and  storage  capacity  are  all  important.  in  other  words,  “the   need  is  to  start  looking  as  widely  as  possible  in  the  largest  set  of  content  sources  possible.  this   need  is  balanced  by  the  practicalities  of  dealing  with  large  amounts  of  information,  so  a  choice     negotiating  a  text  mining  license  for  faculty  researchers  |  williams  et  al   14   needs  to  be  made  of  which  body  of  content  will  most  likely  prove  fruitful  for  discovery.  text  mines   are  dug  where  there  is  the  best  chance  of  finding  something  valuable.”40   when  building  an  xml  corpora  for  research,  hunter’s  research  group  wanted  to  maximize  their   return  on  investment,  so  a  pilot  download  was  conducted  to  assure  that  the  most  beneficial   content  could  be  transferred  smoothly  to  a  local  server.  “permissions  and  licensing  is  only  a  part   of  what  is  needed  to  support  text  mining.  the  content  that  is  to  be  mined  must  be  made  available   in  a  way  that  is  convenient  for  the  researcher  and  the  publisher  alike.”41  this  pilot  phase  allowed   hunter’s  researchers  and  the  vendor’s  technical  personnel  to  clarify  the  requirements  of  the   dataset  and  to  efficiently  deliver  and  accurately  invoice  for  content.  one  of  the  initial  obstacles   was  that  a  filter  for  the  delivery  mechanism  didn’t  exist.  letters  to  the  editor,  errata,  and  more   were  all  counted  as  an  article.  hunter’s  researchers  quickly  determined  that  research  articles  were   most  important  at  this  point  in  the  development  of  the  knowledge-­‐based  analysis  system.  how   should  a  useful  or  minable  article  be  defined—by  its  length,  by  xml  tags  indicating  content  type,  or   by  some  other  criteria?  roeder,  a  software  engineer,  used  article  attributes  and  characteristics   embedded  in  xml  tags  to  define  an  article  as  including  all  of  the  following:     • an  abstract   • a  body   • at  least  40  lines  of  text   • none  of  the  following  tags:  corrigendum,  erratum,  book  review,  editorial,  introduction,   preface,  correspondence,  or  letter  to  the  editor   in  the  end,  hunter’s  research  group  and  the  vendor  agreed  to  transmit  everything  and  allow  the   group  a  fifteen  business  days  to  evaluate  the  content.  the  research  group  would  then  notify  the   vendor  of  how  many  “articles”  were  received.  this  process  would  continue  until  400,000  “articles”   were  received.     after  spending  more  than  a  year  working  to  develop  a  structure  to  purchase  a  large  corpus  of   journal  articles  to  text  mine.  just  as  hunter’s  research  group  was  ready  to  execute  the  license,   remit  payment,  and  receive  the  articles,  their  federal  grant  expired,  stalling  the  purchase.  in   retrospect,  this  unfortunate  development  was  the  catalyst  for  a  shift  in  philosophy  and  strategy  for   the  researchers  and  librarians  at  cu  anschutz.   discussion   xml  text-­‐mining  efforts  will  continue  to  expand,  leading  to  increased  demand  on  libraries  and   librarians  to  play  a  role  in  securing  content.  publishers,  researchers,  and  libraries  see  the  potential   commercial  and  research  value  for  text  mining  journal  content  and  are  driving  the  rapid  evolution   of  this  arena,  in  part,  because  “there  is  increasing  demand  from  public  and  charitable  funders  that   maximum  value  is  leveraged  from  their  substantial  investment  and  this  includes  making  outputs     information  technology  and  libraries  |  september  2014   15   accessible  and  usable.  .  .  .  text  mining  offers  the  potential  for  fuller  use  of  the  existing  publicly-­‐ funded  research  base.”42     however,  publishers  identified  two  main  barriers  to  text  mining  from  their  perspective—lack  of   standardization  in  content  formats  and  in  access  terms—and  concede  that  “publishers  should   develop  shared  access  terms  for  research-­‐driven  mining  requests.”43  from  the  researcher  and   librarian  perspective,  there  are  many  barriers  and  costs  involved  including  “access  rights  to  text-­‐ minable  materials,  transaction  costs  (participation  in  text  mining),  entry  (setting  up  text  mining),   staff  and  underlying  infrastructure.  currently,  the  most  significant  costs  are  transaction  costs  and   entry  costs.”44  the  significant  transaction  costs  stem  from  the  time  it  takes  to  navigate  the   complexity  of  negotiating  and  complying  with  license  agreements  for  journal  content.  the  various   types  of  “costs  are  currently  borne  by  researchers  and  institutions,  and  are  a  strong  hindrance  to   text  mining  uptake.  these  could  be  reduced  if  uncertainty  is  reduced,  more  common  and   straightforward  procedures  are  adopted  across  the  board  by  license  holders,  and  appropriate   solutions  for  orphaned  works  are  adopted.  however,  the  transaction  costs  will  still  be  significant  if   individual  rights  holders  each  adopt  different  licensing  solutions  and  barriers  inhibiting  uptake   will  remain.”45   in  a  survey  of  libraries,  findings  indicated  that  librarians  anticipate  a  new  role  as  facilitators   between  researchers  and  publishers  to  enable  text  mining.46  librarians  are  a  natural  fit  for  this   role  because  they  already  have  expertise  in  navigating  copyright,  requesting  copyright   permissions,  and  negotiating  license  agreements  for  journal  content.  “advice  and  guidance  should   be  developed  to  help  researchers  get  started  with  text  mining.  this  should  include:  when   permission  is  needed;  what  to  request;  how  best  to  explain  intended  work  and  how  to  describe   the  benefits  of  research  and  copyright  owners.”47   after  their  experience  with  developing  a  framework  to  license  and  purchase  a  large  corpora  of   journal  articles  in  xml  format  to  be  text  mined,  fox  and  williams  came  to  believe  that,  in  addition   to  providing  copyright  expertise,  librarians  should  assist  in  reducing  transaction  costs  by   developing  model  license  clauses  for  text  mining  and  routinely  negotiating  for  these  rights  when   the  library  purchases  journals  and  other  types  of  content.  adopting  this  philosophy  and  strategy   led  williams  and  fox  to  successfully  advocate  for  the  inclusion  of  a  text-­‐mining  clause  in  the   license  agreement  for  the  stem  publisher  in  this  case  study  at  the  time  of  the  library’s   subscription  renewal.  this  occurred  at  a  regional  academic  consortium  level,  making  text  mining   easier  at  fourteen  academic  institutions.  furthermore,  the  university  of  colorado  libraries,  which   includes  five  libraries  on  four  campuses,  is  now  working  on  drafting  a  model  clause  to  use  when   purchasing  journal  content  as  the  university  of  colorado  system  and  to  put  forth  for  consideration   by  the  consortiums  that  facilitate  the  purchase  of  our  major  journal  packages.  given  that   incorporating  text  mining  clauses  into  library–publisher  license  agreements  for  scholarly  journals   is  in  its  infancy,  there  are  few  resources  available  to  assist  librarians  adopting  this  new  role.  model   clauses  include  the  following:     negotiating  a  text  mining  license  for  faculty  researchers  |  williams  et  al   16   • british  columbia  electronic  library  network’s  model  license  agreement48   o clause  3.11.  “data  and  text  mining.  members  and  authorized  users  may  conduct   research  employing  data  or  text  mining  of  the  licensed  materials  and  disseminate   results  publicly  for  non-­‐commercial  purposes.”     • california  digital  library’s  standard  license  agreement49   o section  iv.  authorized  use  of  licensed  materials.  “text  mining.  authorized  users   may  use  the  licensed  material  to  perform  and  engage  in  text  mining/data  mining   activities  for  legitimate  academic  research  and  other  educational  purposes.”     • jisc’s  model  license  for  journals50   o clause  3.1.6.8.  “use  the  licensed  material  to  perform  and  engage  in  text   mining/data  mining  activities  for  academic  research  and  other  educational   purposes  and  allow  authorised  users  to  mount,  load  and  integrate  the  results  on  a   secure  network  and  use  the  results  in  accordance  with  this  license.”   o clause  9.3.  “for  the  avoidance  of  doubt,  the  publisher  hereby  acknowledges  that  any   database  rights  created  by  authorised  users  as  a  result  of  textmining/datamining  of   the  licensed  material  as  referred  to  in  clause  3.1.6.8  shall  be  the  property  of  the   institution.”   publishers  are  also  beginning  to  break  down  barriers  perhaps,  in  part,  because  of  the  sentiment   that  “privately  erected  barriers  by  copyright  holders  that  restrict  text  mining  of  the  research  base   could  be  increasingly  regarded  as  inequitable  or  unreasonable  since  the  copyright  holders  have   borne  only  a  small  proportion  of  the  costs  involved  in  the  overall  process;  furthermore,  they  do   not  have  rights  or  ownership  of  the  inherent  facts  or  ideas  within  the  research  base.”51  biomed   central  and  plos  both  offer  services  that  allow  researchers  to  access  xml  text  collections.  biomed   central  makes  content  readily  accessible  by  providing  a  website  for  bulk  download  of  xml  text.52   plos  requires  contact  with  a  staff  member  for  download  of  xml  text.53  in  december  2013,   elsevier  also  announced  that  it  would  create  a  “big  data”  center  at  the  university  college  london   to  allow  researchers  to  work  in  partnership  with  mendeley,  a  knowledge  management  and   citation  application  now  owned  by  elsevier.  while  this  is  a  positive  step,  the  partnership  does  not   appear  to  make  the  data  available  to  research  groups  beyond  the  university  college  london.54     however,  there  is  still  a  long  way  to  go  before  publishers  and  librarians  are  routinely   collaborating  on  opening  up  the  scholarly  literature  to  be  mined.  for  example,  a  2012  nature   editorial  states  “nature  publishing  group,  which  also  includes  this  journal,  says  that  it  does  not   charge  subscribers  to  mine  content,  subject  to  contract.”55  repeated  attempts  by  williams  to   obtain  more  information  from  nature  publishing  group  and  a  copy  of  the  contract  have  proved   fruitless.     in  january  2014,  elsevier  announced  that  “researchers  at  academic  institutions  can  use  elsevier’s   online  interface  (api)  to  batch-­‐download  documents  in  computer-­‐readable  xml  format”  after     information  technology  and  libraries  |  september  2014   17   signing  a  legal  agreement.  elsevier  will  limit  researchers  to  accessing  10,000  articles  per  week.56,57   for  small-­‐scale  projects  with  a  narrow  scope,  this  limit  will  suffice.  for  example,  mining  the   literature  for  a  specific  gene  that  plays  a  known  role  in  a  disease  could  require  a  text  set  under   30,000  articles.  at  elsevier’s  current  rate  of  article  transfer,  a  30,000  article  text  set  could  be   created  in  roughly  three  weeks.  however,  for  large-­‐scale  projects  such  as  hunter’s  research   group’s  knowledge-­‐based  analysis  system  that  require  a  text  set  of  400,000  articles  (or  much   more,  if  not  limited  by  budget  constraints),  nearly  a  year  of  time  would  be  required  to  build  the   corpora.  time  is  one  of  the  most  valuable  commodities  in  computational  biology.  the  elapsed  time   required  to  transfer  articles  at  the  rate  of  10,000  articles  per  week  represents  a  bottleneck  that   most  grant-­‐funded  research  cannot  afford.  speed  of  transfer  will  also  be  a  factor.  researchers   require  flexibility  to  maximize  available  central  processing  unit  (cpu)  hours  because  documents   can  take  from  a  few  seconds  to  a  full  minute  each  to  transfer  to  the  storage  destination.   monopolizing  peak  hours  in  high  performance  computing  (hpc)  settings  may  mean  that   computing  power  is  not  available  for  other  tasks,  although  many  hpc  centers  have  learned  to   allocate  cpu  use  more  efficiently  to  high  volumes.  furthermore,  the  terms  and  conditions  set  by   elsevier  for  output  limits  excerpting  from  the  original  text  to  200  characters.58  this  is  roughly   equivalent  to  two  lines  of  text  or  approximately  forty  words.  this  may  be  insufficient  to  capture   important  biological  relationships  necessary  to  evaluate  the  relevance  of  the  article  to  the   research  being  represented  by  the  hanalyzer  knowledge-­‐based  analysis  system.     conclusion   forging  a  partnership  between  a  library,  a  research  lab,  and  a  major  stem  vendor  requires   flexibility,  patience,  and  persistence.  our  experience  strengthened  the  existing  relationship   between  the  library  and  the  research  lab  and  demonstrated  the  library’s  willingness  and  ability  to   support  faculty  research  in  a  nontraditional  method.  librarians  are  encouraged  to  advocate  for   the  inclusion  of  text-­‐mining  rights  in  their  library’s  license  agreements  for  electronic  resources.   what  the  future  holds  for  publishers,  researchers,  and  libraries  involved  in  text  mining  remains  to   be  seen.  however,  what  is  certain  is  that  without  cooperation  between  publishers,  researchers,   and  libraries,  breaking  down  the  existing  barriers  and  achieving  standards  for  content  formats   and  access  terms  will  remain  elusive.   references     1.     university  of  colorado  anschutz  medical  campus,  university  of  colorado

goal are two strategies that lend themselves to the topics including playing a role with the office for information technology policy (oitp) with regard to technology related public policy and actively participating in the creation and adoption of international standards within the library community. colby riggs (university of california–irvine) represents lita on the office for information technology policy advisory committee. she also serves on the lita technology access committee, which addresses similar issues. the committee is chaired by elena m. soltau (nova southeastern university). the standards interest group is chaired by anne liebst (linda hall library of science, engineering, and technology). yan han (university of arizona) chairs the standards task force, which was charged to explore and recommend strategies and initiatives lita can implement to become more active in the creation and adoption of new technology standards that align with the library community. the task force will submit their final report before the 2011 ala midwinter meeting. for ongoing information about lita committees, interest groups, task forces, and activities being implemented on these and related topics, be sure to check out ala connect (http://connect.ala.org/) and the lita website (http://www.lita.org). the lita electronic discussion list is there to pose questions you might have. lita members have an opportunity to advocate and participate in a leadership role as the broadband initiative sets the infrastructure for the next ten to fifteen years. lita members are encouraged to pursue these opportunities to ensure a place at the table for lita, its members, and libraries. b y now, most lita members have likely heard about the broadband technology opportunities program (btop) and the national broadband plan. the federal government is allocating grants to the states to develop their broadband infrastructure, and libraries are receiving funding to implement and expand computing in their local facilities. by september 30, 2010, the national telecommunications and information administration (ntia) will have made all btop awards. information about these initiatives can be found at www2.ntia.doc.gov (btop), www.broadband.gov (national broadband plan), and www.ala.org/ala/aboutala/offices/oitp/index.cfm (ala office for information technology policy). on september 21, 2010, a public forum was held in silicon valley to discuss e-rate modernization and innovation in education. the conversation addressed the need to prepare schools and public libraries for broadband. information about the forum is archived at blog .broadband.gov. established in 1996, the e-rate program has provided funding for k–12 schools and public libraries for telecommunications and internet access. the program was successful in a dial-up world. it is time to now address broadband access which is not ubiquitous on a national basis. while the social norm suggests that technology is everywhere and everyone has the skills to use it, there is still plenty of work left to do to ensure that people can use technology and compete in an increasingly digital and global world. how does lita participate? the new strategic plan includes an advocacy and policy goal that calls for lita to advocate for and participate in the adoption of legislation, policies, technologies, and standards that promote equitable access to information and technology. karen j. starr (kstarr@nevadaculture.org) is lita president 2010–11 and assistant administrator for library and development services, nevada state library and archives, carson city. karen j. starr president’s message: btop, broadband, e-rate, and lita 3 hoist by their own petard a funny thing happened at ala midwinter. what's more, it was fascinating as well, for it was one of the loveliest examples of "communications dysfunction" i've ever seen. (dysfunction: impaired or abnormal functioning.) librarians-information scientists-have always been concerned with the transfer of information. in recent times, this concern has been explicitly identified as constituting the major component of the profession's domain. whether one interprets information to be the book, and discusses its transfer in terms of acquisitions, circulation, and interlibrary loan, or one interprets information to be datum, and discusses transfer in terms of access, retrieval, and transfer, the fact remains that information transfer is the area of concern of the information profession. yet, as is already evident from the paragraph above, the medium being used to relay the message, the unit which is basic to the process of information transfer, i.e., the word, is a fractious thing. one would think that informationalists would be among the most alert to this frailty of language; yet, though the problem has been addressed at great length by a great many, members of our profession have not been predominant among them. we, too, use words ever more loosely, violate structure ever more often, and transpose jargon ever more freely-unaware, and, apparently, uncaring that in the process we are vitiating the very foundation of our field. and thus, at the palmer house in chicago, during a very balmy january midwinter meeting of the american library association, a select group of professional practitioners who had gathered together to work together found themselves caught in their own trap. they were unable to communicate! information specialists-listening without hearing, reading without comprehending, talking without communicating. it was almost frightening. "network" concerns got defined in terms of the need for reimbursement for interlibraty loan. the phrases "data base interchange," "machine-readable record exchange," and "networking" were being used interchangeably, engendering damaging misconceptions. the distinction between "conb:act negotiation assistance" (which clr will provide the anable serials group) and "contracting" (which clr is not doing here) was not made. legislative "networks" described procedural, not substantive, activity. the jargon of internal revenue code section 4942 ( j) 4 journal of library automation vol. 7/1 march 1974 ( 3) (operating foundation) and the jargon of the technical sector ( operations) were interpreted as being synonymous. and the word standard lost its identity altogether. the irony is overwhelming. like the old adage about the shoemaker's children who don't have shoes, it would appear that it is the information specialists who cannot communicate.-ruth l. tighe, new england library information network editorial board thoughts: events in the life of ital sharon farnel information technology and libraries | june 2018 4 sharon farnel (sharon.farnel@ualberta.ca) is metadata coordinator, university of alberta libraries. at the end of june 2018, i will be ending my time on the ital editorial board. during my term i have had the opportunity to write several “from the board” pieces and have very much enjoyed the freedom to explore a library technology topic of choice. this time around i would like to examine ital as seen through crossref’s event data service. crossref launched its event data service in beta in 2017; production service was announced in late march of this year. event data is “an open data service that registers online activity (specifically, events) associated with crossref metadata. event data will collect and store a record of any activity surrounding a research work from a defined set of web sources. the data will be made available as part of our metadata search service or via our metadata api and normalised across a diverse set of sources. data will be open, audit-able and replicable.”1 using dois as a basis, event data captures information on discussions, citations, references and other actions on wikipedia, twitter, and other services. i thought it might be interesting to see what the crossref event data might say about ital. i used the event data api2 to pull event data using the prefix for all ojs journals hosted by boston college (10.6017). i then used openrefine3 to filter out all non-ital records and then began further examining the data. the data was gathered on may 9, 2018. in total, 313 events were captured. of these, 193 events were from wikipedia, 110 from twitter, and 5 each from the lens (patent citations) and wordpress blogs. the 313 events are associated with 38 ital articles, the earliest from 1973 (volume 6, number 1, from ital’s digitized archive), and the most recent from 2018 (volume 37, number 1). the greatest number of events (126) are associated with an article from volume 25, number 1 (2006) on rfid in libraries.4 the other articles are associated with a varying number of discrete events, from one to 24. looking more closely at the events associated with the 2006 article on rfid, all 126 events are references in wikipedia. these represent references to the english and japanese language wikipedia articles on radio frequency identification. other references from wikipedia are to articles on open access, fast (faceted application of subject terminology), library 2.0 , biblioteca 2.0, and others. what about that article from 1973? it was written by j. j. dimsdale and titled “file structure for an on-line catalog of one million titles.” the abstract provides a tantalizing glimpse into the content: “a description is given of the file organization and design of an on-line catalog suitable for automation of a library of one million books. a method of virtual hash addressing allows rapid search of the indexes to the catalog file. storage of textual material in a compressed f orm allows considerable reduction in storage costs.”5 mailto:sharon.farnel@ualberta.ca events in the life of ital | farnel 5 https://doi.org/10.6017/ital.v37i2.10460 there are only four events associated with this 1973 article, but interestingly all are from the lens,6 a global patent search database. these are a set of related patents, by mayers and whiting, for data compression apparatus and methods.7 there are 110 events associated with twitter, with tweets from 15 different users. the largest number of events, 21, begins with aaron tay, 8 a librarian and blogger from singapore management university, tweeting about a 2016 ital article9 on

computer, as a hobbyist’s tool, to society. the web is still more than a decade away, but the seeds are being planted. with this issue, we introduce a new look for the journal — thanks to the work of lita’s web coordinating committee, and in particular kelly sattler (also a member of the editorial board), jingjing wu, and guy cicinelli. the new design is much easier on the eyes and more legible, and sports a new graphic identity for ital. board transitions june marks the changing of the editorial board. a significant number of board members’ terms expire this june 30, and i’d like to take

automation vol. 5/1 march, 1972 circulation control: off-line, on-line, or hybrid michael k. buckland, bernard gallivan: library research unit university of lancaster, england the requirements of a computer-aided circulation system are described. the characteristics of off-line systems are reviewed in the light of these requirements. on-line systems are then reviewed and their economic viability queried. a "hybrid" system (involving a dedicated mini-computer in the library, used in conjunction with a larger machine), appears to be more cost-effective than conventional on-line working. introduction an important feature of a very small library is the close contact between the librarian, his collections, and his users. over the years as collections and library usage have both increased enormously, librarians have gradually been losing this important "contact." the trend toward increased book use is a desirable one but the sheer pressure of transactions has necessitated the adoption of manual and photographic circulation control systems which concentrate on a restricted range of information about borrowing -notably when a book is due back and who has a given book. computerbased circulation systems offer the prospect of regaining detailed knowledge of book usage-at a price. this paper reviews three approaches. the desirable features of a circulation control system are that: 1. it should "marry" borrower, bo~k, and date information together rapidly and accurately. 2. it should enable rapid, easy consultation of the issue files at any time in order to detect the location of any book. 3. it should be able to immediately detect and register the fact that an item just returned from loan has been requested by another reader. this ability should not be dependent on whether or not the person returning the book has also remembered to bring in a recall notice. hybrid circulation control/buckland and gallivan 31 4. it should prepare suitable overdue notices for books retained too long. 5. it should be possible to produce lists of items out on loan to any given borrower and also to signal "over borrowing" (i.e., having an excessive number of books out on loan at any given time). 6. it should be able to detect delinquent borrowers at the point of issue. 7. when material is returned from loan, the system should amend the circulation records promptly and permit the calculation of any fine. 8. it should facilitate the collection, analysis, .and presentation of the "management information" needed to maintain effective stock control and high standards of service. 9. it should perform these tasks reliably and economically. these requirements vary in importance from library to library, but, with some differences in emphasis they appear to apply equally to both public and university libraries. off-line the commonest approach to computer-aided circulation control is to operate in the off-line mode. well-documented examples are ibm 357's (southern illinois), (2) southampton university library, (phase ii), using friden equipment, ( 3) and the current automated library systems ( als ) ltd. equipment. ( 4) these systems can perform the basic operations of issuing and discharging books in an economical manner but because they are operating in an off-line manner they experience difficulties in mainfig. 1 cards badr.es dials · '~'"m"lli ~ ~ ~i/ alsonly g :-taapping_l,_ _______ .,. receiver i store i .... ___ _ ___ ...j ! c:j or i i l----_j i library i i i ibm 357 collectadata 30.

the future because, with present machines and techniques, on-line working is an inefficient mode of operation unless the computer system is running well below capacity. a further obstacle when sharing facilities is the amount of dedicated storage that must be made available to the library. storage is a much prized commodity and computer centers are unwilling to forfeit valuable storage for any length of time. it should also be noted that no average-sized library will be able to afford or justify possession of its own dedicated computer adequate for on-line working. a library's requirements for storage, printing facilities, and so on would make such an independent system an extravagance since its power would have to be considerable to handle the vast quantities of data input to it, but it would constitute a grossly under-utilized investment compared with the sharing of the facilities provided in a university or local government computing center. the data collection units could be teleprinters or card reading stations with some printing or display facilities. the number and type of such dcu's will depend on the local work load, but we will consider a system using two alpha-numeric card reading stations with printout facilities plus an interrogating printer. an interface into the main computer and a multiplexing device will also be required. in order to answer queries and to control the circulation in a completely on-line manner the dedicated disk must be large enough to hold the issue file, and having gone to the expense of controlling the issue online, it would seem inconsistent to be satisfied with a number-only system. if ~e plan for an expected maximum number of 50,000 records in our issue file at any one time and allow 100 characters per record (i.e., author/ title, class or call number, borrower number, date due back, code to describe the type of loan, i.e., long or short, etc.), the disk must be capable of storing 5 million characters. since it is usual to store the bulk of the circulation control programs on the same disk and to allow certain parts of the disk to be used as work areas, a total store area of 6 million characters, at least, will be required. the cost of providing adequate dedicated disk storage will depend on the local situation but could well cost anything between $30,000 and $50,000 to purchase. the remaining equipment is likely to cost $20,000 and development costs will be greater than with off-line. a "hybrid" circulation control system it is possible to meet all the requirements of a library circulation system in a cost-effective manner by exploiting and combining the main advantages of on-line and off-line working in a hybrid system. the basic structure of such a system is shown in figure 3 (see p. 36) . as can be seen, the mini-computer is sited in the library building and has the various data collection terminals attached locally to it. the mini-computer is also conhybrid circulation control/buckland and gallivan 35 nected via a line to the main computer into and from which it can send and receive data. the important differences between this system and the conventional onor off-line systems are that: 1. the mini-computer spools up the transactions as they occur, into its own storage (either tape or disk). 2. the on-line link to the main computer is only used two or three times each day. this is important, since it implies that the hybrid system does not require continuous on-line facilities. 3. supplementary or full listings show the state of the issue file at a particular time. 4. the recent transactions stored by the mini·computer can be interrogated and, in conjunction with the listings, gives the immediately current state of the issue file. 5. reserved books and delinquent readers have their identifiers stored in the core of the mini-computer to enable their immediate identifi· cation at the point of issue. 6. the necessity for dedicated equipment on the main computer (such as a dedicated disk) is avoided. a fairly heavily used library will be handling approximately 5,000 transactions each day. since these transactions will be either issue or return transactions, in the main, if we allow 100 characters worth of information to identify an issue and 20 characters to identify a return, then on the average we will be handling 300,000 characters worth of information each day. in the hybrid system the mini~computer is acting as a controller to the data collection devices and is spooling this information up onto a magnetic tape until such time as the storage space is becoming full or until a sufficient time has elapsed since the last updating of the records. at this time the mini-computer passes the information on its magnetic tape to the main computer via the on-line link. the duration of the on-line connection might be ten to fifteen minutes owing to line speed limitations. in order . to operate a hybrid system, the library would need two periods of on-line working each day of approximately ten to fifteen minutes each. alternatively the magnetic tape could be physically replaced, the fresh one continuing to record transactions while the full one is carried manually to the main computer. provided that the tapes can be read by the main computer, on-line facilities would not be required. the recent transactions, having been passed to the main computer, will be sorted and merged with the rest of the issue file which would be kept on magnetic tape. the precise nature of the listings produced by the main computer will depend on local factors, such as the duration of the loan period, etc., but could be either a fully revised complete listing or a listing of the most recent transactions to supplement an earlier complete listing. 36 journal of library automation vol. 5/ 1 march, 1972 hybrid computer costs basic computer (includes teleprinter )

which, if purchased with a "trapping store," is th e nearest equivalent to the hybrid system outlined in figure 3. the chief differences are that ( 1 ) the als system operates on numbers only, which, in our view makes it less suitable for university library applications; ( 2) the "trapping store" is inflexible in its capability when compared with a mini-computer of similar cost. in order to utilize the on-line facilities provided b y a mini-computer to the full, it would be possible to handle the "short loan" reserve collections of popular texts (commonly borrowable for a few hours only) in a completely on-line manner. in this respect there would be no reliance on the main machine. it might also be appropriate to use the mini-computer to handle other library data processing tasks.

circulation control system hybrid circulation control/buckland and gallivan 37 last year at the university of lancaster the average cost per issue was 12.72 cents. since the university of lancaster is a new university in great britain, it is in the middle of a period of growth and student numbers are expected to increase from 3,000 to 5,400 in the next five years. this university has also researched into the influence of duplication and loan period adjustment on the availability of stock to prospective users and with the present level of duplication and grades of loan period there is a per capita borrowing rate approaching 80 issues per annum. this figure is expected to increase in the next five years. with these figures as a basis, at least 2 million issues are expected in the next five years. even allowing for the cost of data conversion and the amortizement of hardware over five years, the use of a hybrid circulation control system could be expected to result in an average cost per issue of just under 12 cents. conclusion the costs already mentioned can be tabulated thus: off-line-$13,000-$22,000 on-line-$70,000 h ybrid-$35,000 this suggests that a hybrid system offers complete control over library circulation in a highly cost-effective manner compared with on-line working. whether or not a hybrid system is also to be preferred to off-line working will depend on the individual library context. the trade-off between the marginal advantages and the marginal increases in cost and complexity will depend on the detailed costs and value-judgments specific to each situation. if our diagnosis is correct then most attempts to progress from off-line to on-line working are ill-judged and would appear to have no justification in cost-effectiveness. in our view these developments are unlikely to become fully operational. if they do, their life will probably be short or restricted to limited hours unless exceptional circumstances prevail. such circumstances would include continuing subsidies for research and development or the existence of a system justified on other grounds (e.g., police records) . references 1. michael k. buckland and others, systems

that i can post a question to lita-l or ala connect and get a quick, diverse response to an inquiry. i know that i can call on my lita colleagues to serve as references and reviewers as i move through my career. i also know that i can depend upon lita to help keep me current and well informed about technology and how it is integrated into our libraries and lives. this also gives me an edge in my career. so much of the lita experience is currently gained from attending meetings in person and making connections—those of you who have attended the lita happy hour can probably attest to this. for several years lita has not had a requirement to attend meetings in person and allows for virtual participation in committees and interest groups. several ad hoc methods have developed to allow members to attend meetings virtually. to better institutionalize the process two new taskforces have been formed to look at virtual participation in formal and informal lita meetings. a broadcasting taskforce is charged with making a recommendation on the best ways to deliver business meetings and another taskforce is charged with investigating methods to deliver education and programming to members virtually. both taskforces will pay careful attention to interaction and other attributes of in person gatherings that can be applied to virtual meetings so that we retain the connection-making experience. it is hard to assign monetary value to membership in an association, but we do so every time we make a decision to join or renew membership. when i renew and pay annual dues to lita i affirm that i am receiving value, and i do so without thinking. it is a given that i will renew. in addition to my library memberships i am a member of the wildlife conservation society (the group behind the bronx zoo and several other zoos in nyc). each year as i renew my membership i do a quick cost analysis calculating how many times i visited the zoos and what it would have cost my family if we were not members. but before i can finish that exercise my mind begins to wander and i start to think about the excursions to the zoos-camel rides, newborn animals—and those experiences and the memories created derail any cost recovery exercise. it is impossible to put monetary value on the wonderful experiences my family share during our visits to the zoo (incidentally it is more economical as well). i also feel some pride in contributing to an organization that does such wonderful programming and makes a real difference for animals and our planet. i understand that my membership helps them do what they do best. i don’t do this cost analysis with lita, but perhaps i should. the current price of lita membership is sixty dollars per year, which is about sixteen cents per day. as members we need to ask ourselves if we are receiving in return what a s i write my first president’s message for ital, i am wrapping up my year as vice president and the ala annual conference is fast approaching. the past year has been a busy one—handling necessary division business, including meeting with my fellow ala vice presidents, making committee appointments, planning an orientation for new board members, strategic planning, and attending various conferences and meetings to prepare me for my role as lita president. i am lucky to follow such wonderful leaders as karen starr and michelle frisque, who have both helped ready me for the year ahead. my life outside of lita has been equally busy. i started a new position as the director of weill cornell medical college library earlier this year and have a busy home life with two small children. as usual, i have been juggling quite a bit and often dropping a few balls. my mantra is that it is impossible to keep all the balls in the air all of the time, but when they do drop be careful not to let them roll so far away from you so that you lose sight of them. eventually i pick them up and start juggling again. i know that i am not alone in this juggling exercise. lita members have real jobs and friends, family, and other social responsibilities that keep us busy. so why do we give so much to our profession, including lita? if you are like me, it is because we get so much in return. the importance of activity and leadership in national, professional associations cannot be overrated. my experience in lita and other professional library associations has given me an opportunity to hone leadership skills working with various committees and boards over the years. the achievements that i have made in my career have a direct correlation to my work with lita. as libraries flatten organizational structures, lita is one place where anyone can take on leadership roles, gaining valuable experience. many members have agreed to take on leadership roles in the coming year by volunteering for committees and taskforces and accepting various appointments and i want to thank everyone who came forward. in the coming year i will be working with several officers and committees to develop orientations, mentoring initiatives, and leadership training for our members. i do appreciate that not everyone wants to take on a leadership role in lita. the networking opportunities, both formal and informal, also have been extremely valuable in my career. the people i have met in lita have become colleagues i am comfortable

work will now go to the capable hands of the president-elects of lita, alcts, and llama, who were elected this april. during their term, this new cohort of president-elects will build on the work done by the cross-divisional working groups, in order to present the three-division merger for the membership vote in spring 2020 with more details. another piece of good news is that lita, alcts, and llama will begin experimenting with joint programming in order to kickstart our collaboration while the merger planning continues. the lita board decided to hold the next lita forum in fall 2020. alcts is also planning for its second virtual alcts exchange to take place in spring 2020. lita, alcts, and llama will work together on both program committees of the lita forum and the alcts exchange to provide a wider and more interesting range of programs at both conferences. if the membership vote result is in favor of the three-division merger, then the new division will be officially formed in fall 2020, and the planned 2020 lita forum may become the first conference of the new division. shortly after the 2019 ala midwinter meeting, the lita board decided to commit funds to create and disseminate an online allyship training to address the issues aggressive behavior, racism, and harassment reported at the midwinter meeting.1 since then, the lita staff and the lita board of directors have been closely working with the ala office and several other divisions, alcts, alsc, asgcla, pla, rusa, and united, reviewing options. it is likely that this training will follow the “train-the-trainer” model, in order to generate and expand the pool of allyship trainers who will develop and run the lita’s online allyship training for lita members. our goal is to expand our collective capacity to strengthen active and effective allyship, recognize and undo oppressive behaviors and systems, and promote the practice of cultural humility, which requires ongoing efforts, not just a one-time event. we hope to be able to announce more details soon once the final plan is determined. i would also like to highlight the lita award winners who will be celebrated at the 2019 ala annual conference in washington d.c. and to thank the members of the award committees for their hard work.2 the 2019 lita/ex libris student writing award will go to sharon han, a master of science in library and information science candidate at the university of illinois school of information sciences, for her paper, "weathering the twitter storm: early uses of social media as a disaster response tool for public libraries during hurricane sandy," which is included in this issue. charles mcclure and john price wilkin were selected as the 2019 winners of the lita/oclc information technology and libraries | june 2019 3 frederick g. kilgour award for research in library and information technology and the hugh c. atkinson memorial award sponsored by acrl, alcts, llama, and lita, respectively. charles mcclure is the francis eppes professor of information studies in the school of information and the director of the information use management and policy institute at florida state university. john price wilkin is the juanita j. and robert e. simpson dean of libraries at the university of illinois at urbana-champaign. the north carolina state university libraries will receive the 2019 lita/library hi tech award for outstanding communication in library and information technology, which recognizes outstanding individuals or institutions for their long-term contributions to the education of the library and information science technology field and is sponsored by lita and emerald publishing. other not-to-be-missed lita highlights at the 2019 ala annual conference in washington d.c. include the lita top tech trends program widely known for its insightful overview of emerging technologies, the lita president’s program with meredith broussard, a data journalist and the author of artificial unintelligence: how computers misunderstand the world3 as the speaker, and the lita happy hour, a lively social gathering of all library technologists and technologyenthusiasts. the lita avram camp is also preparing for another terrific all-day discussion and activities this year for women and non-binary library technologists to examine the shared challenges, to network, and to support one another. the lita imagineering interest group has put together another fantastic program, “agency, consent, and power in science fiction and fantasy,” featuring four sci-fi authors: sarah gailey, malka older, john scalzi, and martha wells. the lita membership committee is also preparing a virtual lita kickoff orientation for those who are newly attending the ala annual conference. in this last column that i write as the lita president, i would like to express my sincere gratitude to the dedicated lita board of directors, the always fantastic lita staff, and many lita leaders and members whose creativity, passion, and energy continue to drive lita forward. serving as the chief elected officer of one of the leading membership association in library technology has been a true honor to me, and having such a great team of people to work with has been of tremendous help to me in tackling many dauting tasks. it is often said that all lita presidents face unique challenges during their terms. i can say that this has been certainly true during my term. working together with the alcts and the llama leadership on the three-division merger was a valuable experience and a privilege. while we could not move things as quickly as we hoped, we have built a great foundation for the next phase of the planning and learned many things together along the way. last but not least, i would like to thank everyone who stood for the election and congratulate all newly-elected lita officers: evviva weinraub for the president-elect, hong ma and galen charlton for board of directors at large, and jodie gambill for the lita councilor. i am confident that led by the incoming lita president, emily morton-owens, the capable and dedicated lita leadership will continue to accomplish many great things with energetic and forward-thinking lita members in coming years. the future of lita is brighter with these new lita leaders. good luck and

of a library’s support for virtual reality (vr) and the related extended reality (xr) emerging technologies. the researchers conducted 11 interviews with 13 librarians, embedded it staff, and/or faculty members who were involved in administering, managing, or planning a virtual reality lab or classroom in a library (or similar unit) in a higher education setting. the qualitative analysis of the interviews identified clusters of challenges, which are categorized as either emergent (but solvable) such as portability and training; complicated (but possible) such as licensing and ethics: and/or wicked (but tameable). the respondents framed their role in supporting the wickedness of vr/xr in three basic ways: library as gateway, library as learning partner, and library as maker. five taming strategies were suggested from this research to help librarians wrestle with these challenges of advocating for a vision of vr/xr on their respective campuses. this research also hints at a larger role for librarians in the research of technology diffusion and what that might mean to their role in higher education in the future. introduction political scientists horst rittel and melvin webber coined the term “wicked problems” in the early 1970s to refer to problems that were sufficiently complex that they defied conventional problemsolving methods.1 initially framed as broad social problems, such as food security or climate change, wicked problems are characterized by having ambiguous parameters, shifting requirements and/or stakeholders, and, perhaps more importantly, “no determinable stopping point.”2 such problems are called wicked because they are “diabolical, in that they resist the usual attempts to resolve them.”3 without the possibility of a clear solution, the end product of wicked problems analysis is not to solve the problem but rather to find ways to “tame” them, an approach which runs counter to conventional models of not only planning but also reasoning.4 if taming is the last step in wicked problems analysis, a critical first step is to determine if a given challenge is, in fact, wicked, as that will then determine what tools, perspectives, and strategies will need to be brought to the table. simple problems can be resolved by matching them to known solutions, more complicated problems may be addressed by analyzing engineering solutions, but super complex/messy/wicked problems require an entirely different mindset.5 persistent frustration with the limitations of conventional problem-solving models has led to a proliferation of studies identifying a host of wicked problems, ranging from the global (covid-19 response) to the local (dysfunctional families).6 the present study seeks to apply the framework of wicked problem analysis to the question of the role of academic libraries in supporting emerging technologies, using the integration of vr/xr as a case study. information technology and libraries december 2021 black, white, and grey | ellern and cruz 2 literature review the wicked problem of libraries and technology has been recognized by a number of scholars, each using a different frame of reference, as perhaps fits the inherent ambiguity of a wicked problem. scholars have identified electronic data management, research data management, and ebooks as library problems that are wicked in nature, and howley notes that the question of public access touches on larger social issues that could be described as wicked. 7 a recent article by williams and willet identifies makerspace technology as boundary work, suggesting that it challenges conventional roles and relationships held by libraries and librarians, an approach which implies the existence a wicked problem.8 despite these exceptions, at least one set of library scholars has noted that “there are very few applications [of wicked problems] in librarianship.”9 the present study seeks to make the case that the application of the wicked problems framework to the question of the role of the libraries in emerging technology can illuminate new strategies, roles, and pathways forward. while research on wicked problems in libraries may be limited, the role of libraries in the curation, development, and dissemination of virtual reality (vr)—or using the more encapsulated term of extended reality (xr)—has been extensively written about by library scholars. although it could be argued that the current output reflects the nascent stages of vr/xr as a research field as scholars explore a library’s role with virtual reality (vr), mixed reality (mr), augmented reality (ar), and everything associated with them such as virtual worlds or 3d 360-degree videos, it is clear that, to date, the published works about vr/xr largely fall into two camps: the visionary and the applied. the former contains studies advocating for the integration of vr/xr (and related technologies) as part of a vision of the future for libraries; and the latter are applied studies that booth labels as “technorealistic.”10 in other words, these are descriptions of established practice or suggestions of practical strategies for how a library (or librarian) can actually implement a vr/xr lab or related program.11 what remains in shorter supply are critical and/or empirical studies that situate the development of vr/xr as an institutional capacity into larger, arguably wicked, questions of the evolving purpose and position of libraries. the case of vr/xr presents a distinctive perspective on the wicked problem of the technological orientation of academic libraries. unlike issues such as electronic records management, vr/xr is not part of the core technological infrastructure of a library, nor does it touch directly upon prior core administrative functions, such as collection development or access services. rather, it is perceived as an extension of library services, particularly those related to the evolving educational mission of the academic library and its role as a broader facilitator of information literacy across disciplines. as one library scholar remarks: as libraries are increasingly called upon to support knowledge exchange beyond traditional books and journals, the creation of novel types of research infrastructure will shape the preservation and access expectations of constituents.12 the present study looks at how librarians navigate, or tame, the myriad of challenges that arise not just from rethinking how an academic library engages with technology, but from pushing the boundaries of what library work is (or could be). as the emergence of vr/xr technology begins to cast a larger shadow over higher education, many librarians have argued that academic libraries associated with institutions with high research activity are especially well situated to take on a leadership role, an opportunity that they information technology and libraries december 2021 black, white, and grey | ellern and cruz 3 had largely missed with recent related technologies such as 3d printing. not wanting to be left behind, these libraries have embraced vr/xr technology at a relatively rapid rate. a recent (unpublished) study noted that in 2015, only 3% (n=4) out of the 125 sampled research universities had a vr/xr presence; by 2020, that percentage increased to 66% (n=77), a rate which appears to be outstripping that of technology competitors such as gis, institutional repositories, and data visualization services.13 given the relatively high resource up-front investment required to support vr/xr, it would appear that many university libraries are doubling down on the prospect that vr/xr will be an integral part of their future. the degree to which the rapid adoption of vr/xr will live up its promise remains to be seen, but the present study seeks to illuminate how current librarians are seeking to tame this potentially savage beast. methodology this irb-approved study is based on the qualitative analysis of eleven interviews with thirteen librarians (8), embedded it staff (3), or faculty members (2), all of whom were involved with the adoption of vr/xr technology at their respective libraries. the inclusion criteria for the study were described in the consent document as those people “currently involved in administering, managing, or planning a virtual reality lab or classroom in a library (or similar unit) in a higher education setting.” to identify potential participants, the researchers conducted a web search using the terms “library” and “virtual reality” or “vr” and then utilized a snowball sampling method to generate a list of potential interviewees that included multiple library types (e.g., academic research libraries [arls], public libraries) as well as institutional types (e.g., community colleges). one large library had multiple participants including one librarian and two support staff responsible for the vr room. taken collectively, these participants’ institutions included community colleges (3), public libraries (2), medical libraries (4), and academic research libraries (4), located in either the united states (10) or canada (1). the pool of the us educational institutions (10) represented five different carnegie classifications: associate’s colleges, doctoral universities, doctoral/professional universities, master’s colleges & universities, and special focus four-year institutions. these comprised a mix of small-, medium-, and large-sized institutions (by full-time enrollment, or fte). all the organizations in this study (11) were public institutions. each interviewee received a copy of the possible interview topics in advance, including a list of potential challenges faced by libraries seeking to integrate vr/xr (see appendix a). the list of challenges was crafted from a literature search, as well as the personal experience of one of the researchers, a librarian who oversees a vr lab. each hour-long, semi-structured interview was conducted via zoom, machine transcribed with kaltura, and further edited manually by the researchers. the transcripts then underwent three rounds of coding. first, the researchers independently reviewed the body of transcripts in their entirety and identified emergent themes. in the second round of coding, potential themes were merged into semi-structured coding guidelines, which were used to code each interview separately. in the third and final round, the themes were re-evaluated and adjusted based on feedback from the previous rounds, leading to the identification of a problem-based typology (emergent, complex, wicked). from our process, we gained insight into a myriad of challenges facing libraries as they work to integrate vr/xr into the work that they do. that insight has, in turn, led to the development of a conceptual framework that we believe will be useful to others seeking to wrestle with these challenges in the future. information technology and libraries december 2021 black, white, and grey | ellern and cruz 4 table 1. equipment, staffing, and funding for vr/xr spaces in

even within the relatively small sample of institutions included in our sample, we found that there was a fairly wide range of practice regarding vr/xr library labs, with considerable variance on location, number, and manufacturer of headsets, staffing, and funding as seen in table 1. challenges through our coding process, we identified clusters of those challenges, which we categorized as either emergent (but solvable), complicated (but possible), and/or wicked (but tameable). emergent challenges our respondents identified a number of challenges that are frequently associated with the adoption of emergent technology, regardless of who is choosing to adopt it or what they are choosing to adopt. in other words, any person or place adopting xr (or other types of emergent technology) at this stage of its development is likely to run into similar issues. portability and mobility portability (or lack thereof) was frequently referenced as a limitation of the current technology. the most common headsets purchased for the first generation of library vr lab spaces have physical cords and sensors that have to be plugged in (to high performing computers) during use. one intrepid librarian even described carting around her bulky alienware desktop computers and video displays between campuses, but needing to find a better way because, “it made the computer folks very angry because it’s so delicate and our sidewalks are so bumpy.” she now uses an alienware laptop and some sturdy tripods (for the base stations) on these trips. the lack of portability not only limited the ability of libraries to take vr/xr out of the library for events and in-class presentations, but it also exacerbated existing space constraints, with users having to be literally tethered to cpus, screens, and base stations. as one of our respondents put it, “the biggest issue is that it’s in one place and it’s stuck there.” in this case, manufacturers are aware of the limitations on mobility, and it appears as though wireless headsets will be the next wave of adaptation by the industry. several wireless headsets have already come and gone, as vendors continue to work to overcome both technological and human-centered challenges. the oculus go, google cardboard, and google daydream have all been brought to the market and subsequently been discontinued.14 only one of the libraries we spoke to indicated that they had purchased a wireless headset, and that headset (the oculus go) turned out to be of limited utility. while this next generation of headsets will likely solve a number of operability issues, it also has the potential to compound another challenge noted by most of our respondents, i.e., a lack of sustainable funding for equipment refresh. the majority of our respondents (6 of 8, or 75%) indicated that they purchased their equipment through one-time funding sources, whether internal or external grants (n=6), end-of-year funds, or some combination of these. vr/xr training vr/xr experience remains new to most people outside of the gaming world, so it has fallen largely on librarians to develop introductory training protocols at the level of access to the technology. there are distinctive challenges in introducing vr/xr to a broader audience. some of those challenges may be physical. in its earlier stages, a number of users experienced symptoms such as nausea or seasickness, and while these have been lessened with higher refresh rates and movable information technology and libraries december 2021 black, white, and grey | ellern and cruz 6 lenses, other virtual reality induced symptoms and effects (vrise) continue to emerge with studies of longer-term use.15 two of our librarians expressed concerns that other long-term effects may still be unknown, and both of the public libraries included in this study banned vr/xr use for patrons under 14 years of age until more is known about how it affects developing brains, a recommendation that is now supported by most vendors as well. even for those who do not suffer from physical symptoms, the technology can be disorienting and uncomfortable. this contributes to higher levels of anxiety, which, somewhat ironically, vr/xr has been shown to alleviate in some clinical trials.16 for these reasons, vr/xr labs require staffing not just to safeguard the equipment and ensure its appropriate use, but also to coach users through their new experience. as one of our respondents described her experience, “a lot of people will put on the vr headset and not move because they’re used to computer displays being two-dimensional … it is not common knowledge yet that you can move around and this environment [moves] with you. and they [new users] will just stand there.” coaching someone to move around in a virtual reality environment is not a straightforward endeavor either, as one of our librarians relates: “how do you interact with somebody who can’t see you in a way that’s respectful? because that can be kind of disconcerting if you’ve got a headset on and all of sudden somebody touches your hand?” one of our respondents drew upon her experience as a swimming coach to develop a set of “non-touching” verbal protocols for her student lab assistants to utilize in working with clients who are new to the interior mobility of virtual worlds. other challenges identified by our respondents that might fit into the emerging technologies category include the following: liability, aspects of licensing, physical space modifications, room and equipment management, training curriculum, logistics of engaging with multiple users, availability of apps/games, equipment installation, and evaluation procedures. this list could perhaps also include the need to not only educate patrons on what the emerging technology can do but to advocate for its future significance. as one of our respondents stated, “i think you can write about it and speak about as much as you want. it’s a matter of getting them in there.” complicated challenges unlike emergent issues, complicated challenges are unlikely to be resolved without concerted intervention and leadership and, even then, it is possible that a single or clear solution may not be readily identified. challenges that fall into this category may be described as grey areas, in which future directions remain scattered, unclear, or uncertain. embracing these complexities means that libraries looking to adopt vr/xr currently must be willing to venture out on their own, embracing both the opportunities and the risks inherent in forecasting future technology use. licensing an example of one of these complicated challenges that emerged from our interviews is the issue of licensing. many vr/xr titles are available for free, through services such as steam and the oculus store. all of our respondents indicated that they acquired content via these services. other popular vr/xr academic titles, such as 3d organon anatomy and google tilt brush, are licensed and potential users must pay a fee to access the full functionality of the tool. the challenge is that these licenses are most offered on an individual basis (“for home use only”), a reflection of the primary customer base for vr/xr content creators, e.g., gamers. a number of distributors do offer institutional licenses, but these are primarily for use in companies, with a relatively stable and readily identifiable list of employee users or limited number of stations. some vr/xr distributors information technology and libraries december 2021 black, white, and grey | ellern and cruz 7 offer a lesser-known (and less used) license known as an arcade license (e.g., steam pc café), but the prices are determined based on the assumption that the person renting the software for use will be receiving a fee, an assumption which does not work for libraries who do provide arcadelike services but do so free of charge. in other words, none of these available license types are well-suited for library use; the former too limited, the latter too expensive. as one of our librarians suggested, this is the “sort of the crack that libraries fall into a lot of the time anyway, with regard to [issues such as] document delivery, right, [in which the rule is stated], but it probably doesn’t apply to us in the same way because we’re a library. but it doesn’t explicitly say what i need to do about it.” what this means is that the majority of the librarians we spoke with indicated that they adopted one or more of these license types, but there was discomfort with the maladaptation to library practice and uncertainly as to what might constitute a best practice in the current market space. in the case of vr/xr, this state of affairs is likely due, at least in part, to a lack of awareness of or concern for libraries (or educational labs) as customers on the part of vendors. our respondents indicated that this oversight may be changing, however, as four of the librarians we interviewed reported that game developers reached out to them and negotiated deals in which libraries would receive equipment in exchange for beta-testing new titles with student populations. that said, awareness does not equate to priority, as one of our respondents noted, “i am concerned that we will be one of the last audiences that get some consideration in terms of the functionality that meets the library’s needs.” even if these issues are resolved in the context of vr/xr specifically, it seems unlikely that the complicated problem of “library as customer” will persist with the advent of new technologies and new technology providers. ethics the challenge of vendor relationships is compounded by other emergent ethical issues surrounding the integration of vr/xr into the library. several of the ethical concerns raised by our interviewees are connected to broader social concerns with technology use, such as issues of privacy and security, and others are related to long-standing ethical debates within libraries, such as the degree to which content should be limited by the library. our interviewees had divided opinions, for example, on whether or not the vr/xr lab should offer games. on one hand, the availability of games brought students to the library and engaged them with the new technology. on the other hand, the provision of games constitutes, for some stakeholders, a potentially significant shift away from an academic or scholarly mission for the library. as one respondent put it, “i can’t say that libraries have traditionally not been a place for people to have fun, but i think that’s something that … rubs some people a little bit the wrong way.” another stated, “my big concern at the beginning was that we would put this in and people would [say] … that’s for video games. why did the library buy video games?” the question of including popular content should be a familiar debate to librarians, but the issue is ratcheted up a notch when engagement may also include actions, such as shooting, that may be especially sensitive for college campuses. as one interviewee reflected, “we are a university in the south. and if you had a bunch of white male students that love to go play this game, is that going to make somebody from another group feel uncomfortable or unwelcome or feel like this is not a space for them?” as this example implies, unlike the often private act of reading, vr/xr experiences often take place in virtual places that are at least quasi-public, a venue for which few ethical precedents exist (yet). conversations on the legal and ethical implications of fully virtual information technology and libraries december 2021 black, white, and grey | ellern and cruz 8 crimes, such as rape or robbery, for example, constitute a lively, but so far unresolved, scholarly conversation.17 wicked problems where the challenges faced by libraries get most complicated, however, is when the integration of vr/xr touch upon the more fundamental question of the appropriate roles for libraries in the digital age. our respondents framed their vr labs and services largely within existing roles, e.g., gateway or learning partner, with some attention to emerging roles, such as maker, but they also acknowledged that this adaptation was awkward, solutions were (often) makeshift, and anomalies persist. this suggests the potential for paradigm shifts in the role(s) libraries can play in shaping the intersections of knowledge between the “real” and virtual worlds. library as gateway a number of our respondents connected the library’s adoption of vr/xr technology to its role in providing access to technology for those who may not otherwise have it. this role was especially pronounced in the case of academic libraries located in public universities and public libraries serving a defined community. as one of the respondents described their role, “we’re pleased to have them come and learn how to use these technologies because they’re new and we’re trying to make it more democratized that students can come and use it. they don’t have to pay for it. they don’t have to worry about like a lab being locked away from them. they can come in anytime there’s a staff member and use the stuff where here it will provide them tutorials and instruction if they want to use it.” similarly, another respondent stated, “libraries … offer an entry-level kind of way to engage with this technology in a free way where anyone who is even remotely curious, even if it doesn’t have anything to do with … anything academic, can engage with this stuff.” a third respondent stated that the case they made internally (to their library colleagues) was “to explain the importance of the library philosophy of having equitable access to resources … books are a resource, but technology is also a resource.” we have characterized this role as a gateway, rather than strictly as an access issue, because it also encompasses a vision of a pathway, one which starts in the library but may continue to other places, whether specialized labs in the discipline, in the workforce, or as part of their everyday lives. as one of our respondents put it, “we’re very much about these technologies. they’re here; they’re coming; they’re going to be a big thing soon. and we want our students to know what they are and be comfortable with them. so, we try to position ourselves as a place where they can start learning.” this gateway function is, however, characterized by competing stakeholders, both inside and outside of the library—a defining characteristic of wicked problems. this latter is perhaps best illustrated by looking at issues of accessibility. as the statements above attest, librarians see one of their primary service roles as providing access to technologies such as vr/xr to people who might not otherwise have it. that same sentiment, though, can be flipped on its head when taking other aspects of accessibility into consideration. most vr/xr programs are not ada compliant, whether they are being offered in the physical or virtual public spaces of the library. in its current form, vr/xr is an inherently visual technology, so those who are visually impaired cannot utilize it to the same extent as others. most vr/xr programs require physical movements that may not be possible for those with limited mobility. our librarians have created a few hacks, or workarounds, to provide short-term accommodations for individual students (e.g., a verbal narration of visual interactions), but generally speaking, the technology is not fully accessible. information technology and libraries december 2021 black, white, and grey | ellern and cruz 9 library as learning partner several of our respondents indicated that they saw the library’s adoption of vr/xr technology as an extension of their role as partners in the learning enterprise. this role could be conceived directly, in that the librarian mediates between classroom needs and available vr/xr titles and capabilities. this form of direct mediation could be responsive, i.e., identifying options in response to requests received, or proactive, i.e., identifying options than reaching out to faculty who might wish to avail themselves of them. integrating vr/xr material into the library’s ils the role is especially critical at this stage of vr/xr development, as none of the libraries we spoke to had integrated the available titles into their online, public-facing catalogs or integrated library system (ils). in other words, if a patron wants to know what titles are available, the best way to find out would be to ask the librarian directly and/or visit the vr/xr lab in person. as one librarian put it, “there’s not the infrastructure or the architecture we have around a book. if you were, say, a student in a history class and you wanted to study this thing, there’s no way to discover that as part of the more general resources of the library.” several of our respondents were developing workarounds, such as libguides and web-based directories, but none of these would be accessible through a general search of the library catalog or citation databases. determining how to catalog and/or curate vr/xr artifacts may be challenging and timeconsuming, but it is a problem that has an eventual solution. what is less clear, however, is what the long-term role of the library may be beyond this cataloging function. our respondents consistently indicated that this remains one of the lesser-developed roles for vr/xr in the library, and many identified raising faculty awareness especially as a high priority. while several identified this as essentially a “marketing problem,” it would appear that the challenge extends more deeply. many librarians do not have additional degrees in either educational development or instructional design, which encompasses the practice of matching learning outcomes to technology tools. the two most successful examples of matching learning outcomes to librarybased vr/xr that we heard of were faculty driven, one a project to scan actual human body parts for use in a vr setting; the other a criminal justice project related to empathy education using virtual encounters. these kinds of alignment activities can only occur if there is a tool available to match the proposed learning outcome. most of our respondents lamented the limited availability of titles that are appropriate for use in academic settings, so even if awareness was raised, there may not be sufficient content to meet academic needs. as one librarian suggests, “students will say, i’ve seen the anatomy tool, but right now i’m taking chemistry or i’m taking genetics. do you have anything that will help me with that? i’m a visual learner. i really liked this format. and that’s been challenging for because it’s so new. there’s not a coherence in terms of the titles and subject areas that you get.” and another characterized the issue this way, “it’s like the bargain video bin at walmart. sometimes you have to dig through to find something because it’s just, it’s so new right now.” the issue of availability may seem like an emergent technology issue (as above), but the challenge is further compounded by limitations on capacity, as most library vr labs can only hold one class at a time, and even then, the numbers may be limited, necessitating workarounds such as rotations, remote screen-casting, or extended office hours. even with multiple headsets, most of the time students cannot be in the same virtual reality space together. despite these challenges, information technology and libraries december 2021 black, white, and grey | ellern and cruz 10 many of our respondents were focused on optimizing current capacities, at least in part because of pressure to justify the continued expenditure of both personnel time and equipment costs. this precarious state of affairs is reflective both of tightening university budgets as well as the frequent present of internal sources of resistance from more traditionally-minded colleagues within the library itself (noted tactfully by three of our respondents). bearing all of these factors in mind, it would seem that the question of the long-term sustainability and scalability of vr/xr as a learning service for libraries remains unresolved. library as maker there may be another way to frame vr/xr in the context of libraries. in several cases (n=3), our respondents framed vr/xr not as an extension of classroom-focused service, but rather of support for the research enterprise. as one of our respondents described it, “if they’re still working on a project and they need a thing for this academic project. and then we’re just providing a new way to provide that service, closing some of the research cycle loop, that we’re now part of a different part of that same loop of creating things.” this is a reflection of the changing nature of outputs from scholarly research. previously confined largely to print artifacts, e.g., peer-reviewed journals, researchers are facing an increasing number of choices when it comes to ways to represent the scholarship being created, e.g., knowledge artifacts. this can include artifacts created in, through, or with vr/xr. several of the librarians (n=4) we spoke to mentioned that their vr/xr lab came packaged, in a sense, along with their 3d printing stations. in each case, the librarians noted that the utility of the 3d printers had resonated more readily with library users, and two indicated that they had aspirations to link the two processes in an effort to boost interest in the vr/xr space. for example, one respondent indicated that they wanted users to be able to create an object in a vr/xr program, such as google tilt brush, and then print their creation on an associated 3d printer. libraries have long provided non-3d printing services, largely as ancillary services to support researchers, so this example may, at first glance, appear to be simply a slightly more hightech version of a pre-existing service. these made objects, too, could potentially be stored, cataloged, and disseminated through the library system and/or via a dedicated database such as sketchfab.com. in our interviews, however, the respondents hinted that this linkage (between vr/xr and 3d printing) may actually be a first step towards a more fundamental shift in re-imagining the role of the library vis-à-vis technology. rather than functioning primarily as service providers, emerging technology librarians have the opportunity to become more active (co-)creators of content and facilitators of change. in one case, the vr/xr lab director, also a faculty member, developed partnerships with strategic programs on campus, such as the office of admissions, to generate original content that was specific to their institution. fortunately, the faculty member was able to draw on coding skills she had gained in prior professional roles. in another case, the library partnered with an external developer to generate original content with direct relevance to the community—a project that served to generate interest in the library, vr/xr, and local issues, all at the same time. there is a fundamental difference between a library hosting a maker space and becoming a maker itself. while librarians have traditionally characterized themselves as facilitators of knowledge rather than knowledge creators, there is some evidence that this shift may not be quite as profound as it might appear. this shift began with libraries and librarians scanning digitized items information technology and libraries december 2021 black, white, and grey | ellern and cruz 11 of their siloed special collections and archives. the resulting databases are often treated as published works in and of themselves with the library acting as curator and publisher. in addition, librarians currently hold faculty rank at many research universities and actively present and publish both in library-focused journals, thematic journals (e.g., information literacy), as well as in other venues, often alongside faculty partners.18 the embedded curricular model places librarians in the role of learning designers and as creators of extended, discipline-specific content. it should be noted, too, that content development is not the only “creator” role available. when you build a knowledge management system (like a library catalog), the choices you make serve not just to organize knowledge, but also, to shape that knowledge and, yes, create physical and cognitive pathways to and through it.19 it is perhaps not a coincidence that identifying pathways has been identified as a signature taming strategy for wicked problems. discussion: taming wicked problems our study frames the adoption of vr/xr technology by academic libraries as embedded in the larger wicked problem of library reinvention in a digital age. that said, one of the fundamental characteristics of a wicked problem is not that it is very difficult to solve, but that it is intrinsically unsolvable (or nearly so). this may explain why the question of libraries and technology seems to be a conversation that never goes away, as the question involves a perpetually moving target, embedded in the ever-shifting social, economic, and political dynamics that are taking place well beyond the walls of any library.20 this characterization does not mean, however, that we should not keep trying a variety of strategies to untangle these wicked knots. taming strategy 1: embracing wickedness in a recent essay about learning in higher education, randy bass characterized the wicked problem designation as potentially liberating, rather than discouraging. embracing wickedness serves to move the conversation from thinking of libraries as broken or backward (and therefore, in need of solutions), to a view of the question as a grand challenge, a continual thought experiment that requires ongoing inquiry, thoughtful consideration, and an expansive, rather than reductive, perspective.21 as a grand challenge, the question of libraries and emerging technologies such as vr/xr becomes less of a mad scramble to maintain relevance and more of a scholarly conversation that enhances the role of the library as an inclusive and pluralistic space. in this framework, the questions of whether or not a library should embrace new technology or technology-related service are not bounded by the intrinsic qualities of that technology itself, nor does it mean that libraries everywhere will need to land upon the same, or even similar, technologies, but rather they might seek convergence in the role of libraries as tamers of these wicked problems. taming strategy 2: integrating adaptability the librarians we spoke to generally described their units as falling under the category of “early majority” in roger’s well-known diffusion of technology model, in that they wanted to see evidence that vr/ xr will be useful to others before committing their resources, but they also want to serve a gateway role in introducing promising new technologies to their patrons.22 much of the research on technology diffusion, however, has focused on either end of the curve, i.e., the innovators or non-innovators, and comparatively less research has been done on the role played by those in the middle, such as these libraries.23 by positioning themselves as early majority adopters, academic libraries would potentially be able to articulate a clear and distinct role for themselves vis-à-vis other units within the university that support technology-enabled learning; information technology and libraries december 2021 black, white, and grey | ellern and cruz 12 while also giving themselves the ability to leverage more resources outside of the library itself. the model also has the advantage of providing a sustainable model of re-invention. as a given technology matures along the continuum, the library’s role recedes, enabling it to embrace the next emerging technology. as one of our respondents pointed out, their library used to give training on how to use a mouse and, one day, gateway training for vr is likely to go the same route. taming strategy 3: building networks because wicked problems are complex and ill-defined, taming them is often done by connecting to others with different perspectives.24 our respondents were largely emerging technology librarians who used a number of on-the-ground strategies to tame the wickedness of the task of advocating for a vision of vr/xr on their respective campuses. most of these strategies required creating relationships beyond the walls of the library, e.g., building organizational networks, connecting to community organizations, developing joint, shared, or embedded positions; cultivating faculty champions in academic units, and initiating shared programming. these collaborative strategies resonate with another characteristic of wicked problems, e.g., that they require the ability to think across conventional organizational and disciplinary siloes. taming strategy 4: exercising interdisciplinary imagination and what other role at a university has more experience with this kind of intellectual dexterity than a librarian? our respondents mentioned working with faculty from 14 different disciplines in the context of their responses to our interview questions, and that’s without being asked. as higher education increasingly shifts its attention towards addressing wicked problems, then librarians may be well poised to serve a gateway role in modeling, supporting, and conducting what is now being called “convergent” research.25 this has been described as transdisciplinary inquiry that integrates knowledge from multiple data sources, disciplinary perspectives, and lived experiences in order to confront the world’s most complex problems.26 taming strategy 5: modeling as learning partners in the future of higher education, librarians will have a role to play in developing our students’ abilities to tame these same wicked problems.27 this partnership is not limited to the kind of information and digital literacy needed for cross-disciplinary research. taming wicked problems requires more than a specific set of knowledge or skills, but rather a certain disposition, e.g., a willingness to engage in answering seemingly impossible questions; the flexibility to find pathways through those challenges; the ability to persevere through short-term setbacks; and, above all else, the motivation to support the ability of others to flourish.28 this same set of wicked qualities could easily be applied to all of the respondents in our study, each of whom have succeeded because of their deeply held, intrinsic passion for (and commitment to) the possibilities for what technology and libraries can do together. conclusion the library remains a model of not just individual, but also organizational resiliency. as new technologies such as vr/xr arise, the library as an institution will find ways to weather emerging challenges, resolve complicated problems, and disentangle super complex, i.e., wicked, dilemmas, each of which requires the cultivation of distinctive knowledge, skills, and dispositions. in this study, we argue that the strategies associated with wicked problem solving can serve to strengthen the ability of libraries (and librarians) to serve an active role in our collective future, whether that future is “real” or virtual (or both). information technology and libraries december 2021 black,

(of course i hope that we have gained some new members through this outreach!) clearly we are doing many things right and we should not lose sight of what is great about lita as we work on addressing areas that need improvement. one thing that is consistently great about lita is its annual sponsorship of ala emerging leaders. this year we sponsored two lita members who were part of the 2012 ala emerging leaders cohort: jodie gambill and tasha keagan. both were assigned to a team working on a lita project that asked for a recommendation and plan for the implementation of a lita experts profile system. the team was responsible for identifying the software to employ and creating an implementation plan with ontology recommendations. the team has identified vivo (an opensource, semantic-web application) as the software for the project and will present its findings and implementation plan to the lita board and the ala community at the ala annual conference. the team did an outstanding job on this project and completed the deliverable on time, with very little guidance from lita leadership—a sure sign of leadership! yet, i was often reminded that as we embrace our upcoming leaders, we should not forget that leadership occurs on all levels. one message that i heard throughout my presidency is that lita should do more for mid-career librarians—and this sentiment is shared by members of other organizations in which i am active. this is a challenge that lita leadership is poised to take on as it balances its services to membership. as i now count eighteen occurrences of the word “open” in this column i believe i have made my point and it is time to sign off. although i am finishing up my duties as lita president, i am not saying goodbye. i look forward to my new role as past-president, particularly in hosting the 2012 lita national forum in columbus, ohio (october 4-7): new world of data: discover. connect. remix. the national forum planning committee led by susan sharpless smith has done an outstanding job putting together an excellent meeting. the committee has lined up interesting speakers such as eric hellman, ben schneiderman, and sarah houghton, and thoughtfully evaluated many paper and poster submissions. i am sure we will all learn quite a bit from our colleagues as we attend sessions and network. i will be hosting a dinner and i hope to see some of you there as i enjoy what i hope will be a more relaxed role as past-president. it has been an honor to serve you and i look forward to working with lita in the years to come! microsoft word june_ital_nelson_final.docx what’s  in  a  word?  rethinking  facet   headings  in  a  discovery  service       david  nelson  and   linda  turney     information  technology  and  libraries  |  june  2015           76   abstract   the  emergence  of  discovery  systems  has  been  well  received  by  libraries  who  have  long  been   concerned  with  offering  a  smorgasbord  of  databases  that  require  either  individual  searching  of   databases  or  the  problematic  use  of  federated  searching.  the  ability  to  search  across  a  wide  array  of   subscribed  and  open-­‐access  information  resources  via  a  centralized  index  has  opened  up  access  for   users  to  a  library’s  wealth  of  information  resources.  this  capability  has  been  particularly  praised  for   its  “google-­‐like”  search  interface,  thereby  conforming  to  user  expectations  for  information  searching.   yet  all  discovery  services  also  include  facets  as  a  search  capability  and  thus  provide  faceted   navigation  that  is  a  search  feature  for  which  google  is  not  particularly  well  suited.  discovery  services   thus  provide  a  hybrid  search  interface.  an  examination  of  e-­‐commerce  sites  clearly  shows  that   faceted  navigation  is  an  integral  part  of  their  discovery  systems.  many  library  opacs  also  now  are   being  developed  with  faceted  navigation  capabilities.  however,  the  discovery  services  faceted   structures  suffer  from  a  number  of  problems  that  inhibit  their  usefulness  and  their  potential.  this   article  examines  several  of  these  issues  and  offers  suggestions  for  improving  the  discovery  search   interface.  it  also  argues  that  vendors  and  libraries  need  to  work  together  to  more  closely  analyze  the   user  experience  of  the  discovery  system.   introduction   the  emergence  of  google  as  the  premier  search  engine1  has  had  a  very  profound  effect  on  searcher   expectations  regarding  information.2  by  virtue  of  its  simplicity  and  the  remarkably  powerful   search  algorithms  that  enable  its  highly  relevant  results,  the  simple  search  box  of  google  has   clearly  triumphed  as  the  preferred  way  to  find  information.     but  is  the  google  search  model  really  the  panacea  that  libraries  need  to  resolve  their  search   interface  requirements?  the  nature  of  search  engine  and  search  interface  design  is  a  very  complex   issue.  unfortunately  for  academic  libraries,  google  has  dominated  discussions  and  thinking  about   search  engine  interfaces:  “just  google  it!”  is  a  simple  google  search  box  really  the  preferred   vehicle  with  which  libraries  should  be  delivering  their  content,  both  licensed  and  unlicensed?     the  assumption  librarians  make  to  justify  the  use  of  a  google  model  is  that  library  users  are   essentially  google  users,3  or  that  they  have  the  same  information  searching  needs.4  this  is  a     david  nelson  (david.nelson@mtsu.edu),  is  chair,  collection  development  and  management,  and   linda  turney  (linda.turney@mtsu.edu)  is  cataloging  librarian,  james  e.  walker  library,  middle   tennessee  state  university,  murfreesboro,  tennessee.     what’s  in  a  word?  rethinking  facet  headings  in  a  discovery  service  |  nelson  and  turney   doi:  10.6017/ital.v34i2.5629   77   flawed  assumption.  as  an  academic  library,  we  are  tasked  with  making  discoverable  not  simply   digital-­‐only  information,  but  information  objects  with  discrete  characteristics  that  often  constitute   the  object  of  a  search,  e.g.,  an  audio  book,  a  film,  or  even  a  book  on  a  shelf.  google  has  put  the   emphasis  on  the  keyword,  with  remarkably  gratifying  results  for  the  average  lay  user.  however,  a   recent  project  information  literacy  study  concluded  that  “google-­‐centric  search  skills  that   freshmen  bring  from  high  school  only  get  them  so  far—but  not  far  enough—with  finding  and   using  the  trusted  sources  they  need  for  fulfilling  college  research  assignments.”5  until  now,  the   library  web  development  focus  on  providing  a  “google-­‐like”  search  has,  unfortunately,  diverted   attention  from  an  appreciation  of  the  developments  in  other  areas  of  the  internet  world,  such  as  e-­‐ commerce,  where  searching  for  information  is  an  integral  component  of  the  buyer–seller   relationship.     commercial  entities  have  a  vested  interest  in  developing  their  websites  to  enable  each  user  to   have  a  successful  search  outcome.  while  the  search  interfaces  routinely  encountered  at  various  e-­‐ commerce  sites  may  seem  obvious,  it  is  important  to  remember  that  one  is  looking  at  a  series  of   deliberate  decisions  made  with  regard  to  the  interface  organization  and  structure.  for  companies,   the  search  interface  represents  millions  of  dollars  in  investment,  and  the  design  is  part  of  their   search  engine  optimization  strategy.6  in  this  way,  companies  and  other  organizations  create   robust  search  interfaces  that  enable  visitors  to  effectively  and  efficiently  find  what  they  want  in   the  company  “knowledgebase.”     it  is  clear  that  the  product  search  industry  has  arrived  at  some  very  significant  conclusions  about   user  search  behavior,  and  that  they  strive  to  optimize  their  interfaces  to  accommodate  those   conclusions.  three  features  stand  out:  (1)  the  importance  of  facets  as  a  key  component  in  the   search  design;  (2)  the  personalization  of  the  text  that  instructs  the  user;  and  (3)  intelligibility  of   facet  labels.  in  a  blog  article  on  facets  in  e-­‐commerce  websites,  scharnell  advises  that,  when   determining  what  the  facets  are,  there  are  two  rules  to  follow:  (1)  keep  it  simple;  and  (2)  create  an   intuitive  structure.7     the  primary  goal  of  a  commercial  website  is  to  bring  about  what  is  called  conversion—that  is,   getting  someone  to  the  site  (driving  traffic)  and,  ultimately,  making  a  sale  (the  conversion).   companies  have  discovered  that  facets  are  the  key  to  enabling  their  potential  customers  to  locate   discrete  pieces  of  information  (e.g.,  a  product)  almost  intuitively.  broughton  observes  that  “there   is  an  evident  faceted  approach  to  product  information  in  many  commercial  websites.”8  an   important  characteristic  of  the  faceted  structure  is  that  it  enables  the  user  to  have  the  ability  to   browse  a  collection.  thus  the  goals  of  a  commercial  site  successfully  employing  faceted  navigation   is  not  that  different  from  the  objectives  which  a  library  discovery  layer  seeks  to  accomplish.  while   the  literature  on  information  literacy  is  now  vast,  very  few  articles  deal  with  the  role  that  facets   play  in  the  discovery  process  for  student  searchers.  fagan  is  an  author  who  has  addressed  this   issue  of  facets.9  ramdeen  and  hemminger  discuss  the  role  of  facets  in  the  library  catalog.  10  to   date,  reviews  of  discovery  systems  or  catalog  interfaces  tend  to  place  emphasis  on  helping  patrons     information  technology  and  libraries  |  june  2015           78   to  search  our  demonstrably  flawed  systems  rather  than  considering  the  interfaces  as  the  actual   source  of  problems  for  users.11   while  it  can  be  argued  that  comparing  an  academic  site  and  a  commercial  site  compares  apples   and  oranges,  there  being  little  connection  between  the  complex,  open-­‐ended  subject/research   questions  and  searching  a  company’s  inventory  of  goods.  however,  there  are  elements  of   commonality  at  the  higher  level  of  an  information  need  that  drive  an  individual  to  perform  any   kind  of  information  search.  in  both  the  subject/topic  search  and  the  product  search  there  is  a  need   to  evaluate  results  as  they  appear  and  to  make  various  decisions  while  going  through  a  search   process  to  limit  and  narrow  a  search.  that  is,  for  the  information  that  libraries  seek  to  make   discoverable,  it  is  often  their  extratextual  characteristics  that  are  every  bit  as  important  as  the   content  itself.     this  leads  to  a  discussion  of  facets,  the  various  attributes  by  which  we  can  further  describe  the   “manifestation”  and  the  “expression”  (using  the  frbr  sense  here)  of  an  intellectual  creation.  we   need  to  pay  more  attention  to  the  importance  of  facets  as  a  critical  component  of  the  search   process.  that  is,  we  must  begin  to  move  away  from  the  mantra  that  our  single  search  box  will   provide  a  successful  result  without  additional  considerations,  with  the  idea  that  the  facets  are  of   secondary,  even  tertiary  importance.  badke  observes  “that  users  of  google  actually  need  a  deeper   level  of  information  literacy  because  google  offers  so  little  opportunity  to  nuance  or  facet   results.”12     yet  facets  are  a  key  part  of  our  discovery  interface  design.  however,  a  full  and  successful   exploitation  of  their  possibilities  has  been  significantly  hobbled  by  a  use  of  jargon-­‐heavy   terminology  that  assumes  users  will  immediately  and  instinctively  grasp  the  concept  of  a  faceted   term.  even  a  superficial  study  of  many  successful  commercial  websites  quickly  leads  the   thoughtful  observer  to  the  conclusion  that  their  web  developers  and  designers  have  been  making   excellent  use  of  focus  groups  and  surveys  to  make  the  search  process  as  easy  as  possible.  while   businesses  have  an  obvious  monetary  incentive  to  make  sure  their  users  do  not  leave  a  site   because  the  site  itself  presented  a  problem,  libraries  have  the  same  interest  in  making  sure  our   users  are  equally  able  to  easily  search  our  site.  a  library’s  site  should  not,  by  its  assumptions  about   the  user,  present  obstacles  to  their  search  success.13   with  the  growing  use  of  discovery  systems,14  academic  libraries  are  entering  into  a  new  phase  of   search  engine  deployment.15  by  making  use  of  a  preindexed  database  rather  than  the  more   restrictive  federated  search  process,  the  discovery  service  interface  allows  a  user  to  search  for   content  in  a  wide  variety  of  publication  and  media  types  (e.g.,  journals,  books,  dictionaries,  audio   books,  videos,  manuscripts,  newspapers,  images,  etc.).  to  assist  searchers,  discovery  systems   provide  faceted  navigation  along  with  the  search  box  interface.  several  studies  have  shown  that   the  use  of  facets  in  the  library  environment  has  proven  effective  in  assisting  searchers.16  however,   it  is  equally  clear  that  library  vendors  have  not  thought  deeply  about  the  facet  category  labels,  and   libraries,  which  can  do  a  certain  amount  of  customization,  tend  toward  unquestioning  acceptance     what’s  in  a  word?  rethinking  facet  headings  in  a  discovery  service  |  nelson  and  turney   doi:  10.6017/ital.v34i2.5629   79   of  the  vendor-­‐supplied  labels.  this  is  a  critical  area  involving  both  the  user  interface  and  the  user   experience;  libraries  and  vendors  need  to  spend  far  more  time  and  effort  on  ensuring  the   intelligibility  of  the  facet  labels  and  on  finding  effective  ways  to  encourage  their  use.   the  presence  of  facets  is  a  standard  feature  for  all  library  discovery  systems.17  however,  as  we   will  show  below,  facet  labels  are  not  easily  understandable  for  the  average  user  and  our  search   systems  tend  toward  emphasizing  our  users  as  “anonymous  service  recipient(s).”     what  are  facets?  a  review  of  various  discussions  of  facets  in  information  retrieval  literature   reveals  the  elasticity  of  the  term,  along  with  related  terms.18  will  observes  that  “what  a  facet  is  has   been  stretched  .  .  .  and  the  term  is  used  loosely  to  mean  any  system  in  which  terms  are  selected   from  pre-­‐defined  groups  at  the  time  of  searching.”19  it  is  probably  easiest  to  understand  the  use  of   the  term  facet  in  information  retrieval  systems  as  categories  derived  from  the  universe  of  objects   that  one  is  seeking  to  discover,  whether  we  are  dealing  with  manufactured  products  at  home   depot  or  greek  manuscripts  in  a  library  collection.20  what  adds  to  the  problem  of  definition  is  the   number  of  synonyms:  “the  term  facet  is  commonly  considered  as  analogous  to  category,  attribute,   class  and  concept.”21  how  objects  are  grouped  would  most  logically  determine  the  facets  that  are   necessary  for  the  classification  scheme.  it  is  the  objects  that  are  under  a  facet  that  present  a   problem  in  understanding.  niso  z39.19  defines  facets  as  “attributes  of  content  objects   encompassing  various  non-­‐semantic  aspects  of  a  document,”22  thus  including  such  things  as  author,   language,  format,  etc.  the  terms  that  are  indexed  are  not  the  facets  but  rather  concepts  that  exist   in  a  unique  relationship  to  the  facet.  “homer”  is  indexed  under  a  facet  “author,”  but  indexing  the   term  author  is  meaningless.     another  source  of  confusion  is  the  failure  to  distinguish  between  facets  and  filters,  both  of  which   are  used  to  refine  or  narrow  a  search.23  when  a  search  interface  states  that  it  is  using  “faceted   navigation,”  usually  both  facets  and  filters  are  present.     because  both  a  facet  and  a  filter  are  part  of  retrieval,  it  is  often  difficult  to  separate  the  two.  once   again,  we  encounter  a  terminological  problem.  for  example,  one  can  speak  of  how  a  facet  itself  is   used  to  filter  a  search  in  the  sense  that  it  refines  or  narrows  a  search  to  a  smaller  segment  of  the   universe  of  objects.  here  the  term  filter  refers  to  the  process  of  narrowing  a  search.  but  we  also   have  filters  that  deal  with  ranges.  thus,  the  filter  “date”  covers  a  range  of  time,  from  say  one   month  or  one  year,  to  a  range  over  a  specific  period  of  time.  the  same  can  be  seen  for  the  filter   “price,”  used  to  specify  only  one  amount,  say  $5,  or  a  range  from  $100  to  $299.  the  critical   difference  between  a  facet  and  a  range  filter  is  that  the  terms  found  in  a  facet  are  indexed  while  a   range  filter  (e.g.,  date  or  price)  is  not  an  indexed  term.  it  is  important  to  maintain  a  clear   distinction  between  a  facet  and  a  range  filter  because  the  underlying  metadata  is  different.  a  range   filter  sorts  the  content  in  a  specific  way  and  at  the  same  time  narrows  the  results.     our  examples,  along  with  the  closer  analysis  of  the  ebsco  eds  discovery  system  below,  will  amply   demonstrate  that  facets  and  filters  are  extremely  effective  in  information  retrieval  systems.  the     information  technology  and  libraries  |  june  2015           80   challenge  that  libraries  face  is  the  need  to  make  sure  that  users  are  aware  of  their  presence  on  a   search  interface  rather  than  relying  exclusively  on  keywords  alone  and  solely  on  the   algorithmically  based  result.24  the  value  of  the  faceted/filtered  search  is  the  ability  to  lead  the   searcher  quickly  and  efficiently  to  the  desired  result,  a  result  that  will  too  often  elude  the  user   even  with  a  powerful  google  search,  unless  that  user  gets  most  of  the  terms  exactly  right.   we  chose  various  e-­‐commerce  websites  because  they  have  extremely  large  numbers  of  site  visits   or  because  they  were  smaller  specialty  sites  that  reflected  a  more  highly  optimized  use  of  facets.  a   wide  range  of  product  types  was  in  the  selection.  the  frequency  of  visits  indicates  that  large   numbers  of  users  are  exposed  to  a  search  page  structure  and  terminology,  which  in  turn   establishes  a  standard  for  a  set  of  user  expectations.  best  buy,  target,  and  home  depot  are  among   the  top  on  hundred  accessed  websites,  a  fact  richly  indicative  of  the  type  of  influence  they  will   have  in  setting  user  search  expectations.  an  examination  of  these  websites  reveals  an  underlying   set  of  best  practices  for  making  use  of  faceted  navigation  with  text  searching.   linguistic  personalization   with  the  advent  of  web  2.0  there  are  several  forms  of  interaction  an  individual  can  have  with  a   website.  these  can  be  considered  forms  of  personalization  of  websites.25  usually,  personalization   is  “largely  about  filtering  content  to  satisfy  an  individual’s  particular”  information  needs.26  we  see   personalization  at  its  most  complex  in  the  algorithmically  adjusted  results  to  a  search  based  on   previous  searches.  there  we  find  the  feature  of  suggestions  that  are  offered  to  an  individual  on  the   basis  of  search  results,  a  feature  offered  by  amazon  and  netflix.  while  we  will  not  be  able  to   personalize  our  discovery  services  in  a  manner  similar  to  netflix  or  amazon,  we  can  improve  the   quality  of  the  interaction  in  other  areas  of  “personalization.”  we  should  be  seeking  ways  we  can   more  directly  speak  to  individual  searchers,  for  example,  by  selecting  words  and  phrases  that   speak  directly  to  a  person’s  needs.   our  examination  of  many  e-­‐commerce  sites  reveals  a  robust  use  of  linguistically  personalized   features  as  an  intrinsic  part  of  their  website  design  and  enhancement.  that  is,     e-­‐commerce  sites  make  use  of  their  interface  itself  to  directly  communicate  with  their  customers   in  a  way  that  makes  use  of  certain  linguistic  features  that  can  be  easily  adopted  by  library  sites.   combined  with  faceted  searching,  adding  certain  linguistic  features  should  prove  effective  in   encouraging  the  use  of  the  facets,  and  in  the  process  improve  both  the  search  results  and  the  user   experience.  this  constitutes  the  fundamental  challenge  for  the  academic  library—to  help  shape   the  mental  model  with  regard  to  the  universe  of  content  that  we  provide  through  our  search   interface.  finally,  there  is  what  we  can  consider  a  form  of  linguistic  personalization  with  which   language  is  used  to  “speak”  more  directly  to  a  searcher.  it  is  this  third  feature  of  linguistic   personalization  that  libraries  can  more  easily  control  and  customize  with  the  discovery  services,   as  well  as  at  other  places  on  the  library  website.     what’s  in  a  word?  rethinking  facet  headings  in  a  discovery  service  |  nelson  and  turney   doi:  10.6017/ital.v34i2.5629   81   there  is,  of  course,  the  personalization  that  is  intended  primarily  for  those  who  register  and  then   set  up  their  own  accounts.  however,  there  is  also  the  personalization  in  terms  of  text   communication  in  which  the  website  uses  both  pronouns  and  verb  forms  that  directly  address  the   searcher.  this  is  seen  in  the  use  of  the  second-­‐person  pronoun,  either  the  subject  or  the  possessive,   “you”  or  “your,”  and  for  verbal  forms,  the  use  of  the  second-­‐person  imperative  (usually  the  same  as   the  infinitive  in  english).  this  type  of  personalization  is  a  web  design  decision.  the  search  box   now  frequently  contains  text,  ranging  from  simple  noun  lists  to  sentences,  all  of  which  are   intended  to  encourage  the  user  to  make  use  of  the  search  capabilities.  after  a  search  has  occurred,   the  results  are  also  indicated  with  text  that  speaks  directly  to  a  person  by  means  of  the  use  of   pronouns  and  verbs.  we  find  the  following  interesting  examples  in  table  1:   pronoun   site   notes   what  are  you  looking  for  today?   kroger   search  box   what  can  we  help  you  find?   home  depot   search  box   what  are  you  looking  for?   lowe’s   search  box   your  selections   target   post-­‐search   we  found  x  results  for  [search  term]   target   post-­‐search   narrow  your  results   tigerdirect   post-­‐search   table  1.  linguistic  personalization  examples   in  examining  the  features  that  are  found  at  these  e-­‐commerce  sites,  it  is  interesting  to  note  the  use   of  either  of  two  words  for  the  facet  instructions:  refine  or  narrow,  two  words  our  users  will   routinely  encounter  in  nonlibrary  searching.     the  various  sites  all  have  the  following  elements:   1.  search  box   2.  search  results  outcome  clearly  shown   3.  facet  instruction  [“refine,”  “narrow,”  “show”]     4.  facets         information  technology  and  libraries  |  june  2015           82   major  problems  with  library  discovery  interfaces   we  can  identify  three  important  areas  that  need  to  be  considered  with  the  discovery  interface   design:   1.  the  search  box  itself   2.  the  facet  labels  and  their  intelligibility   3.  getting  the  user  to  the  facets  area     the  library  search  box   the  search  box  makes  an  excellent  point  of  departure  for  implementing  improvements  of  the   library’s  discovery  interfaces.  note  that  companies  do  not  assume  prior  search  knowledge  on  the   part  of  their  potential  market;  they  explicitly  tell  people  what  they  can  do  in  the  search  box.  as  we   see  in  table  1,  many  companies  (e.g.,  home  depot  and  lowe’s)  are  choosing  to  use  entire   sentences,  not  merely  clipped  phrases  or  strings  of  nouns.     many  libraries  are  beginning  to  populate  the  search  box  with  text.  however,  that  text  is  often   simply  a  noun  list  of  types  of  formats,  e.g.,  articles,  books,  media,  etc.  it  is  important  to  point  out   that  there  is  an  implicit  expectation  of  an  action  present  in  a  search  box.  but  too  often  when  our   library  websites  supply  a  list  of  nouns,  we  are  assuming  that  we  are  answering  the  question  in  the   mind  of  the  searcher—they  are  looking  for  a  subject  or  topic—and  we  supply  a  string  of  nouns   that  enumerate  formats.  so  right  from  the  beginning,  we  find  a  mismatch  between  the  user’s   purpose  when  coming  to  a  library’s  search  box  and  our  arbitrary  enumeration  not  of  topics,  but  of   types  of  information  sources.   once  we  recognize  this  problem,  we  have  some  very  good  options  to  choose  from  in  terms  of   personalizing  the  search  box  in  a  way  that  is  more  analogous  to  what  home  depot  and  lowe’s   offer:   1.  what  are  you  looking  for?   the  sentence  above  is  colloquial;  it  is  exactly  what  a  person  would  expect  to  hear  when   approaching  a  reference  librarian  or  from  a  service  counter  experience  in  a  variety  of  settings.   2.  what  are  you  searching  for?   this  is  a  more  complex  concept  because  it  includes  what  can  be  considered  a  technical  term   (“search”),  a  word  now  commonly  understood  within  the  context  of  searching  for  information  and   not  only  applicable  to  a  lost  dog  or  strayed  notebook.     this  simple  adjustment  matches  the  user’s  intent  with  a  clearly  stated  purpose  in  the  search  box.   there  are  additional  ways  we  can  enrich  the  search  box  that  will  assist  the  users  in  their  queries.       what’s  in  a  word?  rethinking  facet  headings  in  a  discovery  service  |  nelson  and  turney   doi:  10.6017/ital.v34i2.5629   83   both  examples  use  the  pronoun  you  so  that  the  sentence  speaks  directly  to  the  individual  searcher.   there  is,  of  course,  the  option  to  just  use  a  verb  in  the  imperative:  “search  for  .  .  .”    or  “enter   [keywords,  terms,  etc.]”.  however,  the  added  feature  of  the  pronoun  you  promotes  the   involvement  of  the  participant-­‐searcher.  see  also  the  interesting  article  by  thompson  on  the  use  of   personal  pronouns  in  social  media  communications  by  university  students.27     facets  column   all  library  discovery  services  make  use  of  facets.  since  the  facets  column  does  constitute  a  far   more  challenging  area  of  linguistic  personalization  for  the  discovery  interface,  the  incorporation  of   specific  types  of  design  features  should  be  employed  to  immediately  attract  the  attention  of  the   user  to  the  facets  column.  this  is  a  very  complicated  area  that  deals  with  user  behavior,  interface   design,  etc.  how  do  we  direct  the  user’s  attention  to  the  facets  column,  let  alone  to  be  aware  of  the   facets  on  the  lefthand  side?  we  can  add  a  note  after  a  search  that  says  something  to  the  effect  of   “too  many  results/hits?  try  narrowing  your  search  with  the  facets  below.”  although  this  involves   difficult  interface  design  issues,  it  is  very  important  that  we  begin  to  think  more  seriously  about   ways  to  draw  our  users  into  the  search  process  more  intuitively  and  effectively.  if  we  don’t,  we   will  find  the  continual  underutilization  of  an  incredibly  powerful  searching  feature.   we  also  know  that  users  routinely  ignore  advertising  banners  so  often  that  the  literature  has   christened  this  tendency  “banner  blindness”;  in  the  same  way,  if  our  facet  labels  are  meaningless,   they  will  be  overlooked.28  we  condemn  the  discovery  service  interface  to  the  same  fate  if  we  are   not  careful  to  choose  meaningful  labels  that  make  sense  when  the  “average”  student  or  faculty   user  encounters  them.  currently,  we  are  also  assuming  knowledge  on  the  part  of  our  users  that  is   clearly  misplaced  or  we  anticipate  a  much  greater  success  with  instruction  than  is  usually   warranted.  there  are  several  studies  that  show  the  disparity  between  the  searcher’s  self-­‐ assessment  and  the  reality  of  the  actual  skill  possessed.29   one  of  the  main  problems  users  experience  with  search  engines  is  their  inability  to  narrow  their   searches,  especially  because  we  are  now  dealing  with  such  a  large  array  of  information  source   types.30  this  is  where  the  use  of  facets  comes  into  its  own.  as  we  seek  to  make  the  discovery   interface  the  first  and,  eventually,  probably  the  only  primary  interface  to  our  selected  resources,   the  user  needs  to  know  how  to  easily  find  a  video  or  a  sound  recording  as  well  as  a  pertinent   article.  this  should  be  done  through  an  easily  accessible  and  understandable  search  interface.  the   success  of  the  e-­‐commerce  sites  in  making  effective  and  profitable  use  of  facets  amply   demonstrates  the  value  of  facets  even  for  complex  research  questions  and  topics.   this  brings  up  the  matter  of  naming  conventions  for  the  facets.  it  is  clear  that,  despite  the  newness   of  discovery  services,  the  facet  labels  simply  continue  the  naming  conventions  that  are  used  in   databases.  we  know  from  usability  studies  that  library  jargon  is  a  stumbling  block  for  our  users.31   when  we  do  not  pay  close  attention  to  the  appropriateness  of  each  facet  category  label,  we  simply   continue  the  utilization  of  a  terminology  that  is  foreign  to  the  understanding  of  many  of  our     information  technology  and  libraries  |  june  2015           84   users,32  undermining  the  use  of  a  powerful  searching  feature  merely  because  of  user  ignorance  of   the  terms.  an  honest  appraisal  of  the  discovery  interface  will  bring  us  immediately  face-­‐to-­‐face   with  one  of  our  primary  legacy  library  problems,  our  heavily  jargon-­‐laden  vocabulary.  in  fact,  we   are  actually  dealing  simultaneously  with  two  problems—the  facet  labels  that  are  chosen  and  the   complexity  of  the  information  universe  that  discovery  systems  expose.  at  a  presentation  on   discovery  services  at  the  2014  ala  annual  conference,  one  speaker  went  so  far  as  to  say  that   facets  are  not  used  in  discovery  searches.33  this  underscores  the  unpleasant  reality  that  we  are   dealing  with  both  a  design  problem  and  an  intelligibility  problem,  not  the  failure  of  facets  as  a   navigational  feature.  at  a  recent  loex  presentation,  one  school  had  already  thrown  in  the  towel   and  will  concentrate  on  teaching  academic  search  premier  over  the  discovery  service  primo.34   again,  this  reveals  that  users  are  having  a  problem  with  the  interface  and  its  display  content.     suggestions  for  improving  facets  and  the  facet  labels   currently,  the  facet  labels  in  library  discovery  service  interfaces  are  limited  to  a  list  of  nouns  that   designate  the  facets  that  can  be  used  for  narrowing  or  limiting  a  search.  however,  the  labels  that   we  use  may  not  be  meaningful  to  our  users  and  are  simply  a  list  of  nouns  that  are,  by  and  large,   not  really  understood.35  second,  a  facet  label  is  also  intended  to  have  the  user  do  something,  hence   a  verb  of  action  is  implied.  in  standard  classification  taxonomies,  the  facet  is  used  for  organizing   and  grouping  the  objects  that  will  be  included  in  the  facet.  for  a  discovery  system,  the  facet  is   there  to  lead  the  searcher  to  content  on  the  basis  of  the  content’s  differing  characteristics  as   expressed  through  a  facet.  one  has  to  ask  the  question,  exactly  why  would  a  student  do  something   simply  because  that  student  sees  a  noun  on  the  lefthand  side?  we  need  to  provide  more  context   during  the  search  process.   below  we  make  recommendations  that  we  think  will  enhance  the  intelligibility  and  the  usability  of   facets.36  it  will  be  important  for  libraries  and  vendors  to  do  substantial  user  experience   investigations  into  the  various  options  that  are  available  for  use  on  a  discovery  page.  our  goal  is  to   draw  attention  to  the  current  inadequacies  in  how  facets  have  been  implemented  in  discovery   services  and  to  encourage  a  more  systematic  approach  to  this  important  area  of  our  library   information  delivery  capabilities.     1. as  observed  above,  in  the  e-­‐commerce  sites,  the  facet  is  indicated  by  the  presence  of  an   icon  marker  that  allows  for  the  facet  to  expand  and  contract.  in  our  sample  of  sites,   there  was  a  parity  between  using  the  +/-­‐  sign  or  a  triangle  (a  full  triangle,  not  a  right   and  downward  chevron).  eds  made  the  decision  to  go  with  the  chevron  symbol.  this  is   a  user  interface  issue  and  one  that  needs  further  examination  and  testing.  we  think   that  the  +/-­‐  sign  is  a  more  suitable  visual  icon  indicator  for  a  user  to  take  a  specific   action.  +/-­‐  also  have  a  value  attached  to  them  that  says  to  a  user  “yes”  for  the  +  sign  and   “no”  for  the  -­‐  sign,  thereby  signaling  a  user  to  expand  (+)  or  contract  (-­‐)  a  list.  we  want   to  attract  users  to  the  facets  and  to  take  an  action.       what’s  in  a  word?  rethinking  facet  headings  in  a  discovery  service  |  nelson  and  turney   doi:  10.6017/ital.v34i2.5629   85   2. make  sure  that  only  facets  and  filters  are  collapsible  and  expendable  and  that  the   design  interface  makes  this  clear.   3. the  term  limit  is  often  found  in  discovery  systems.  this  is  a  term  that  was  not  found  in   our  sample  of  e-­‐commerce  sites.  the  two  primary  terms  are  refine  and  narrow.  the   advantage  of  using  these  terms  is  that  one  can  more  easily  personalize  this  feature,   “narrow  your  results  to”  [full  text]  [scholarly    .  .  .]  [date];  these  are  two  words  that   users  normally  see  when  searching  e-­‐commerce  sites.   4. the  facet  “source  types”  is  a  common  facet  label.  this  is  obscure  terminology  that  users,   especially  students,  tend  not  to  know.  a  suitable  option  to  personalize  this  category   could  be,  “what  type  of  information  do  you  need?”  and  then  list  the  types.  at  least  by   asking  the  question,  a  user  will  be  encouraged  to  look  at  the  possibilities  available,  e.g.,   academic  journals,  trade  publications,  magazines,  etc.     in  the  following  list  of  facets,  we  can  see  that  the  facets  themselves  are  inherently  contradictory  or   do  not  actually  represent  what  they  purport  to  be.  this  is  not  an  argument  against  facets;  rather,   we  need  to  rethink  exactly  what  we  do  want  our  metadata  to  do.  to  simply  take  up  space  on  the   facets  column  does  not  serve  any  purpose.  it  is  also  clear  that  we  need  to  systematically  monitor   the  use  of  facets,  and  for  this  we  need  analytics.  at  this  point,  it  is  difficult,  if  not  impossible,  to   know  whether  facets  have  been  used  for  searches  and,  if  so,  which  facets  have  been  used.  until  we   routinely  gather  this  sort  of  data,  we  will  not  have  the  appropriate  data  to  make  suitable  decisions   about  facets  and  their  use.   1.     language—this  facet  represents  the  language  (both  written  and  spoken  content)  of   the  work.  while  the  term  language  is  understood  by  users,  we  need  to  consider   whether  the  word  alone  triggers  a  response.  since  users  most  likely  want  only  english,   the  facet  label  can  ask  that  question,  and  then  the  selection  of  language  choices  will   appear,  making  it  clear  that  there  are  other  choices  as  well.     a  question  like  “do  you  want  english  only?”  will  then  elicit  a  response  to  narrow  the   results  by  language.  with  the  majority  of  the  materials  in  english,  this  may  be  moot,  but   it  does  encourage  the  searcher  to  think  about  the  language.   the  discovery  layer  adds  the  facet  term  “undetermined”  when  the  provided  metadata   does  not  specify  the  language  of  a  work.  in  a  sense,  the  metadata  has  holes  and  a  user   that  is  searching  for  a  particular  language  will  inadvertently  exclude  relevant  search   results  if  the  facet  is  used  too  soon  to  filter  out  undesired  languages.  we  recommend   that  filtering  by  language  should  be  used  only  as  necessary  and  only  when   overwhelmed  by  a  large  number  of  unwanted  languages.     2.     publisher—this  facet  represents  the  entity  or  the  issuer  of  a  published  work.  this   applies  across  both  serial  and  nonserial  materials.  the  user  most  likely  understands   this  term.  but  the  question  is,  what  is  the  value  of  this  facet?  while  we  do  have  the     information  technology  and  libraries  |  june  2015           86   metadata  for  this,  it  is  difficult  to  understand  the  circumstances  under  which  one  will   actually  limit  a  search  by  the  publisher.  we  suggest  not  displaying  this  facet.   3.     publication—this  facet  represents  the  source  title  of  the  published  work,  such  as  a   journal,  trade  magazine,  or  newspaper.  this  applies  primarily  to  articles,  book  reviews,   columns,  etc.,  and  not  to  publications  like  books,  sound  recordings,  and  videos.  the   user  must  be  made  aware  that  the  use  of  this  facet  should  be  used  for  serial-­‐type   materials  only.  alternatives  to  “publication”  can  be  “article  source.”  this  facet  answers   the  implicit  search  query  and  could  be  a  pop-­‐up  window:  “what  journal  or  magazine   are  you  looking  for?”   4.     content  providers—this  is  a  very  problematic  facet.  it  is  not  difficult  to  surmise  that   most  users  when  encountering  this  term  would  not  know  what  it  means  and,  more   significantly,  why  it  is  important.  in  fact,  the  term  itself  is  not  accurate—another   interesting  issue  that  must  be  dealt  with.  the  “content  providers”  may  not  be  the   actual  providers  of  content  but  rather  providers  of  the  metadata  content,  which  is   something  altogether  different.  for  example,  emerald  is  the  actual  content  provider  for   an  article,  yet  a  different  provider,  the  metadata  provider,  is  listed  as   the  content  provider.  a  suggested  replacement  for  this  term  is  “sources.”  wordings  for   a  pop-­‐up  window  could  be,  “to  narrow  your  search,  choose  from  a  source  that  most   closely  matches  your  topic.  the  sources  are  from  different  types  of  subject  databases.”     5.     subject—the  use  of  the  facet  “subject”  may  seem  to  be  obvious,  yet,  upon  closer   inspection,  the  nature  of  this  facet  is  problematic.  what  is  the  cognitive  connection   between  first  doing  a  keyword  search  and  then  seeing  on  the  lefthand  side  the  facet   label  “subject?”  why  should  a  user  assume  he  or  she  should  now  click  on  a  link  called   “subject,”  since  they  just  finished  doing  a  subject  search?  we  need  to  provide  the   context  for  an  action  that  takes  into  account  the  most  common  experience  of  the  user.   using  the  term  “topic”  rather  than  “subject”  would  allow  us  to  offer  a  term  that  is  more   congruent  with  the  familiar  vocabulary  of  a  student’s  classroom  experience  because   generally  students  are  directed  to  research  topics.     a  university  of  washington  libraries  usability  study  from  the  prediscovery  era  (2004)  found  that   users  preferred  “browse  subjects”  to  “by  subject.”  37  here  we  see  the  presence  of  a  verb  specifying   an  action.  the  significant  finding  for  our  purposes  from  this  earlier  study  is  the  fact  that  users   found  the  phrase  with  a  verb  more  meaningful  than  the  phrase  with  a  preposition.  we  suggest   making  it  clear  that  the  user  can  further  refine  the  search  by  the  suggested  subjects  that  are  listed   in  the  facets  by  using  the  phrase  “narrow  your  topic”  or  “further  narrow  your  topic.”  the  pop-­‐up   window  could  say,  “to  narrow  your  search,  choose  from  this  list  of  possible  topics  that  most   closely  match  your  search  terms.”     what’s  in  a  word?  rethinking  facet  headings  in  a  discovery  service  |  nelson  and  turney   doi:  10.6017/ital.v34i2.5629   87   the  conclusion  reached  by  the  university  of  arizona  study  is  even  more  relevant  for  the  discovery   layer  interface:  “we  learned  that  if  students  have  no  idea  why  or  when  they  should  use  an  index,   they  will  not  choose  a  link  labeled  index,  no  matter  how  well  designed  the  web  page  is.”38  this  is   the  situation  with  facet  labels.  if  they  are  not  intelligible,  or  at  least  provoke  some  response  to  a   question  posed,  they  will  be  ignored,  and  if  ignored,  their  potential  value  goes  completely  unused.     conclusion   e-­‐commerce  has  concluded,  in  the  face  of  overwhelmingly  positive  evidence,  that  facets  are  an   essential  aspect  of  the  successful  (i.e.,  profitable)  user  experience  and  that  they  have  been  almost   universally  adopted  by  companies  who  sell  products,  have  very  large  product  lines,  and  need  to   lead  their  customer  to  exactly  the  type  of  product  they  want.  in  our  discovery  layers,  we  also  need   to  develop  the  kinds  of  features  that  promote  the  effective  use  of  the  resources  we  offer  our   academic  users,  and  build  in,  where  feasible,  appropriate  features.  modifications  can  and  should   be  made  as  libraries  work  with  their  discovery-­‐services  vendor  to  rationalize  an  interface  page   that  should  include  natural  language,  easily  understandable  navigation,  logical  taxonomic  ordering   of  the  facets,  etc.  in  essence,  both  product  searches  and  academic  information  searches  present   the  same  scenario:  we  begin  with  an  information  need,  a  retrieval  system,  and  the  need  to  achieve   recall,  precision,  and  relevance.     discovery  services  allow  for  an  information  search  to  be  carried  out  essentially  as  a  google  search   while  limiting  the  scope  of  facets  to  assistance  in  refining  it.  we  can  be  confident  that  our  users,   many  (or  even  most)  of  whom  also  use  e-­‐commerce  faceted  search  sites,  are  able  to  recognize  a   similar  search  interface.  thus  we  are  dealing  with  an  important  design  issue.  but  to  what  extent   do  our  users  take  advantage  of  faceted  searches?  as  it  stands  at  this  writing,  the  link  between  the   facets  and  their  corresponding  content  “documents”  (articles  or  video)  is  simply  not  clear.  the   characteristics  of  our  discoverable  objects  must  be  tied  in  with  what  a  user  would  be  likely  to   understand.   we  need  analytics  capable  of  supplying  this  sort  of  critical  user-­‐experience  information.  it  may  be   that  we  are  perhaps  dealing  with  conflicting  mental  models  about  information  searching.  students   and  other  members  of  the  academic  community  may  simply  not  be  adequately  cognizant  of  the   implicit  faceted  nature  of  their  query,  and  this  becomes  a  new  opportunity  for  improvements  in   our  approach  to  user  instruction.     it  is  clear  that  libraries  and  vendors  need  to  work  together  to  properly  evaluate  the  facet  labels  if   facets  are  to  begin  to  achieve  their  potential  as  an  essential  search  function.  disheartening   statements  to  the  effect  that  no  one  uses  them,  or  that  the  discovery  system  itself  is  already   branded  a  failure,  demonstrates  that  the  discovery  layer,  while  clearly  a  powerful  tool  for   integrating  a  range  of  accessible  resource,  is  still  in  its  infancy.  our  purpose  in  this  paper  was  to   draw  attention  to  both  the  proven  value  of  faceted  navigation  and  the  ongoing  problem  of     information  technology  and  libraries  |  june  2015           88   confusing  or  inadequately  understood  library  terminology  that  is  presently  hindering  what  should   be  a  powerful  tool  in  our  information  discovery  warehouse.   references     1.     google  is  ranked  number  1  according  to  alexa,  a  traffic-­‐ranking  website.  “the  top  500  sites  on

editor's note: the editor and author are aware that varying approaches may be taken to the problem presented here. readers are invited to respond in the form of a paper or a technical c.'ommunication. in discussion about search keys, concern has been expressed as to how the nwnber of items tetrieved by a single value relates to collection size. this paper creates a statistical model that attempts to give some insight into this behavior. it is concluded that, in general, the observed behavior can be explained as being intrinsically statistical in nature rather than being a property of specific search keys. an attempt is made to relate this model to other tesearch, and to indicate how this model may be made to yield more accurate predictions. introduction various experiments suggest that it may be possible to develop, as an access route into a file of bibliographic records, a search key'" whose values can be easily derived from such bibliographic data as is likely to be available to its users.1 some concern, however, has been expressed regarding the nonuniqueness of these keys: if the number of items retrieved were often to exceed an amount easily handled by a user of the system, the value of this access route would be considerably diminished. accordingly, an important measure of search key performance is the frequency with which a large number of records is reh·ieved as the search key is applied to the file. this measure is · related, for example, to how many memory accesses will be required, on the average, to retrieve all records satisfying a request; it is also an important consideration in deciding which display device should be installed in a system.2 • 3 after evaluating such a measure for a search key on a particular file, it is reasonable to ask how that measure will change over time, as the file increases in size. the nature of this variation has already been of concern to researchers in the field. kilgour, on the basis of a· number of experiments carried out at oclc, notes that "there remains a major problem to be o by the. phrase "search key'~ we mean a key similar to the 3-3 or 3-1-1-1 keys used at · ohio college library center and other places, which is made up by concatenating truncations of bibliographic data elements. llo journal of library automation vol 6/ 2 june 1973 solved and a major question to be answered. the problem is constituted of those replies that contain a number of entries exceeding the optimal maximum .. .. the major question to be answered is how truncated search keys will perform on files ten and a hundred times the size of that used in this experiment."' he elsewhere observes that "as a file of bibliographic entries increases, the maximum number of entries per reply does not increase in a one-to-one ratio ... . "5 this paper presents a mathematical model that addresses itself to the problem defined by kilgour and attempts to explain his observation; it is suggested that the gross features of the behavior are statistical in nature and not properties of specific search keys. a view of collection growth the cause of the phenomenon observed by kilgour can best be understood by first considering a simple model which, while not itself valid, does cast light on the nature of the behavior. this first model neglects the effect of randomness both in the growth of the collection and in the arrival of requests. it supposes our search key has the following property: regardless of collection size, the fraction of the collection retrieved by a particular search key value, v~, is exactly given by a constant f;; thus, if the fil e holds n records, a request for v 1 will retrieve n 1 = f,n records. this model similarly assumes that among any sizeable number of requests, the fraction of the time any particular search key value will occur is fixed; thus, for any subset of search key values, it is possible to determine how often members of that subset will occur among a set of requests. in particular, for any integer n, we can form the set of all the search key values that will retrieve less than n items. we can then determine how often search key values from that set are requested. if, for example, requests for these values occur 99 percent of the time, then we can assert that 99 percent of the time less than n items will be retrieved. if the fil e contains n items, then these n items constitute the fraction f = ~ of the file. should the collection size increase to ln, then the model predicts that 99 percent of the time less than f( ln) = ln items would be retrieved. in other words, we have precisely the behavior kilgour observes does not occur. this argument shows that a simple deterministic model does not conform to experience with search keys. the model breaks down in two ways, which accounts for the discrepancy between the results derived from it and kilgour's observations: 1. in any actual library, the fraction of the time that a particular request will appear within a sequence of requests will vary; and 2. in comparing two different samples having the same size, the number of items having a given search key value will vary. the first of these factors is easily dealt with and its analysis will suggest the number of requests to use in a test of search key behavior in a given library. for a particular collection, lets denote the set of search key values statistical behavior of search keysj bookstein 111 for which, say, twenty or more items are retrieved. we would like to find the fraction of the time that a request in s occurs in the long run; suppose this value is in fact q. then among m requests, the probability that m members of s occur is given by the binomial distribution fb(m\q,mi). this distribution has a mean of qm and a variance of qm(1 q). should we desire to estimate the actual fraction of the time that twenty or more items will be retrieved, we can take a sample of m requests and compute q, the fraction of the requests with search key values in s; if we do so, we will usually get a value for q between q ,/ m v q ( 1 q) and q + v2 m v q ( 1 q) .' if for example, q = .01 and m = 10,000, we would tend to find q in the interval .01 ± .002. thus the effect of randomness in the arrival of requests can easily be controlled by increasing the number of requests considered; furthermore, the size of error can be predicted. we next introduce the second factor; its analysis will suggest how the behavior of search keys will change as the collection grows in size. for this purpose we adopt a model of collection growth which assumes that as items arrive, they are randomly distributed among the search key values in accordance with some probability distribution. if we suppose that the probability of an item being assigned a specified search key value, v11 is p11 then in a collection of n items we may conclude that the probability of n items having that value is given by the binomial distribution: ( n ) n n-n fu(n jpbn) = 7 p1(1p1 ) • if g' ( v;) is the probability that the value v1 is selected from the request population, then the probability that the "next" request retrieve n items is given by def ~~ g'(vt) fb(njp;,n) =fg(p) fb(njp,n)dp; g(p) dp= ~ g'(v;) p;! p i ~ p + dp is the probability that a request arrive with value p1 in the interval (p,p + dp), and will be treated as a continuous function.""' since the expectation of the binomial distribution is given by pn, we have de£ nfpg(p)dp = np as the expected number of items retrieved by a random request; since this is proportional ton, doubling the size of the collection will, on the average, double the amount of material ret1·ieved. similarly, the 2 2 variance, u 2, is given by n2 ( p 2 p ) + nf p( 1 p) g( p )dp. should p2 p , de£ the variance of p, be small, this reduces to nfp(l p )g(p )dp = i?n, so that approximately 95 percent of the time the amount of material retrieved would be less than np + 2\1 n a-= n ( p + , ~a) . v n . •• this result would more precisely be expressed as f fb(n lp ,n)dg(p), which has the form of a stieltjes integral. the expression used in the text is simpler and reasonably valid because of the vast number of values the search key can take. i i i j i 112 journal of library automation vol. 6/2 june 1973 it is the factor + 2cf p vn' and its dependence on n, that may account for kilgour's nonlinearity, and not any property intrinsic in the nature of any type of search key. thus, to the extent that this model reflects what is really happening, the 95 percent point increases roughly proportionately with file size; the "constant" of proportionality, however, is the sum of two tem1s: the first is a true constant, and the second is a term that approaches zero as the file gets larger. in particular, this model suggests that we will never reach a leveling off point-as the file increases in size, the number of items retrieved will also increase, and the pattern of increase will become increasingly linear. up to this point this discussion has been qualitative in nature, being based upon general statistical considerations and making use of the normal approximation to some unknown distribution; its broad conclusions are, however, consistent with the findings of earlier workers and can explain certai11 unanticipated properties of search keys. to proceed further it will be necessary to restrict the form of the function g(p); tl1is will be attemped in the following section of this paper. relationship of model to earlier research interest in access methods that are appropriate for files of bibliographic data has generated a considerable amount of empirical research on search key behavior. of necessity, this pioneering work has been of a descriptive nature, resulting in data showing search key behavior in specific environments. while these efforts have lent a good deal of insight into the nature of search keys, the basic weakness of such research lies in the difficulty of extending these findings to other situations. one purpose of a mathematical model such ·as. the one being developed here is to provide this increased generality by representing in a concise and easily manipulated form the results of previous research. it is accordingly of interest to indicate the relationship between previous work on search keys and our model. research on search key performance has been of two kinds. the fi.rst kind seeks .to answer the question: for any number, n, how many search key values retrieve n items? the answer to this question depends only on the search key and the collection; it is independent of the pattern of request arrivals. the second kind of research involves the ·actual arrival of requests; it tries to answer the question: for any number n, how frequently will requests resulting in the retrieval of n items occur? to discuss this research in terms of our model requires a closer examinadef tion of the function g( p) previously defined. we recall that g( p) dp == ~ g'(v1), with dp being a small number. thus g(p) is determined p ~ pi ~ p+dp by two factors: statistical behavior of semch keysjbookstein 113 a. the number of search key values in the interval ( p,p + dp). let us denote this value by f(p )dp, so f(p) is the density of search keys at p. we make use here of the fact that although the number of possible search key values is finite, the number is very large, so their. distribution can be thought of as continuous. b. the average probability of search keys, with values p 1 near p, being requested. we shall refer to this quantity as g"(p). by combining these factors we have g(p) = g"(p )f(p ). · in terms of this discussion, the first type of research described above. is in fact estimating f(p): if there ares search key values that retrieve n items from a collection of n items, then sis an estimate of this relation uses _!_ f (~)· n n' n + ~~ n = pn, and dp = n n~ 1 n n' the second kind of research directly estimates g ( p). guthrie, in a recent paper, provides a bridge between the two types of research by discussing his findings in terms of two models.6 one of his models, which asserts that each search key value has an equal chance of being requested, is equivalent to the assumption that g"(p) = 1, and g(p) = f(p). guthrie finds that this is not an adequate representation of his data. guthrie's second model asserts that each item has an equal chance of being requested. in our terms this becomes g' ( p )ap, and g( p )apf ( p). this model, while an improvement over the first, still disagrees with the data. furthermore , these models do not estimate f ( p); even if guthrie's model were correct, we would not know the probability that n items would be re trieved until we were told how many search key values contained n items. in the next section we will try to remedy this situation by means of a two paramete r representation of g( p). a representation of f(p) to get a more detailed account of search key behavior by experiment is difficult since the two aspects of randomness already discussed are confounded; the experimenter only sees the combined effect. we will, however, try to estimate the distribution g ( p) by a distribution of the form (a + {3 + 1)! a (1 )f3 a!f3! p p. we believe that such an attempt is reasonable on three grounds: a. it is not possible to find g(p) exactly, and moreover, it is not clear that this would be desirable. we are interested in a reasonable approximation that is satisfactory for decision-making purposes; b. the above distribution assumes a wide variety of shapes as a and f3 vary; it seems likely that values of a and f3 can be found for which 114 journal of library automation vol. 6/ 2 june 1973 this distribution is close enough to g ( p); and c. this distribution is mathematically tractable. if we proceed using the above approximation for g(p ), we find: (i) the probability, p(n), of n items being retrieved is given by 1. p(n) = (-n) ~-+ f3 + 1~l(a + n)! (nn + [3)! n a!fj! (a+fj+n+l)! ( ii) the expected number of items retrieved, e, is given by a + 1 2. e == n a + {3 + 2 ; and (iii) the variance, v, of the number of items retrieved is given by _ a+l {3 + 1 n 3· v n a + f3 + 2 a + {3 + 3 ( 1 + a. + {3 + 2 ) · if the experiment is performed on a small sample, the expectation and variance can be computed and the values of a and f1 estimated from the relations e a (1 -) + 1 4. f1== n 2, and e n v en e 1 -n 5. a. v 1 e l e 1-n usually ~ will be much smaller than one; in this case we may use the approximations: n 4'. f3 =(a+ i)e, and e 5'. e 1 a= n. once a and f1 have been evaluated, we can compute the probabilities p ( n) for files of arbitrary size, and with these values we can make assertions regarding the probability of, say, more than 30 items being retrieved. a relation that can be derived from formula 1 and may be of use when comparing this model with experiment is: p(n) i + {3 n-n = 1 + a n + 1 p(n + 1) statistical behavior of search keys/ bookstein 115 the probability of zero retrievals is likely to be an extraordinary point in the distributions g ( p) and p ( n) since it is influenced by the knowledge that a user may have of the collection; this effect is likely to be encountered in a sampling process in which the requests have to be generated artificially. in such cases it would be advisable to treat p ( 0) as an empirically derived parameter, (), and use the modified formula { (jifn=o 6. p' (n) = (1 fj) 1 ~(;~o) if n ::1= 0. the value of() can be estimated by the fraction of requests retrieving zero items; for sampling techniques using only productive requests, () will be zero. a. and f3 can be calculated as before from the mean and variance of the sample. conclusion the above discussion is intended as an attempt to provide some theoretical understanding of the puzzling behavior discovered in the use of search keys and also to provide some guide for those experimenting with samples of such files. we do, however, urge caution for the latter uses. an analysis similar to the above can be useful under several different circumstances, such as: determining the future behavior expected of a search key in a single library as the collection grows; determining the behavior for one library based upon experiments conducted on a different but similar library; and extrapolating from the performance of a search key in a sample of the collection to its pedormance in the full collection. if one wishes to compare two different libraries, one can note that as far as search key values are concerned, a particular library's collection can be thought of as a random sample of the larger population from which it selects its material, and accordingly the formula for p ( n) should be valid. in this case, if two different collections are drawn from the same population, the g ( p) refers to this population and the libraries are distinguished by the parameter n; when we are considering samples from a single library, then n is the sample size and g ( p) refers to the library itself. no theoretical basis exists at present for estimating to what extent the populations being considered depend upon the type

is possible that they can be broken down, e.g., by language, into subpopulations that are stable and for each of which the analysis is valid. acknowledgments this work was made possible by clr/ neh

resources through shibboleth article off-campus access to licensed online resources through shibboleth francis jayakanth, ananda t. byrappa, and raja visvanathan information technology and libraries | june 2021 https://doi.org/10.6017/ital.v40i2.12589 abstract institutions of advanced education and research, through their libraries, invest substantially in licensed online resources. only authorized users of an institution are entitled to access licensed online resources. seamless on-campus access to licensed resources happens mostly through internet protocol (ip) address authentication. increasingly, licensed online resources are accessed by authorized users from off-campus locations as well. libraries will, therefore, need to ensure seamless off-campus access to authorized users. libraries have been using various technologies, including proxy server or virtual private network (vpn) server or single sign-on, to facilitate seamless offcampus access to licensed resources. in this paper, authors share their experience in setting up a shibboleth-based single sign-on (sso) access management system at the jrd tata memorial library, indian institute of science, to enable authorized users of the institute to seamlessly access licensed online resources from off-campus locations. introduction the internet has both necessitated and offered options for libraries to enable remote access to an organization’s licensed online content—journals, e-books, technical standards, bibliographical and full-text databases, and more. in the absence of such an option for remote access, faculty, students, and researchers have limited and constrained access to the licensed online content from off campus locations. as scholarly resources transitioned from print to online in the mid-1990s, libraries and their vendors had to start identifying user affiliations in order to grant access to licensed online resources to the authorized users of an institution. the ip address was an obvious mechanism to do that. allowing or denying access to online resources based on a user’s ip address was simple, it worked, and, in the absence of practical alternatives, it became the universal means of authentication for gaining access to licensed library content.1 to facilitate seamless access to licensed online resources from off-campus sites, libraries have been using various technologies including proxy server or vpn server or remote desktop gateway or federated identity management or a combination of the said technologies. in our institute, the on-campus ip-based access to the licensed content is supplemented by vpn technology for off-campus access. the covid-19 pandemic has necessitated academic and scientific staff work from home, which demands smooth and seamless access to the organization’s licensed content. the sudden surge in demand for seamless off-campus access to the licensed online resources had an impact on the institute’s vpn server. also, not all

visvanathan 2 institute are entitled to get vpn access. to mitigate the situation, the library, therefore, had to explore a secure, reliable, and cost-effective solution to facilitate seamless off-campus access to all the licensed online resources to all the authorized users of the institute. after exploring the possibilities, the library decided to implement a single sign-on solution based on shibboleth. shibboleth software implements the security assertion markup language (saml) protocol, separating the functions of authentication (undertaken by the library or university, which knows its community of end users) and authorization (undertaken by the resource provider, which knows which libraries have licenses for their users to access the resource in question). 2 about the indian institute of science (iisc) the indian institute of science (iisc, or “the institute”) was established in 1909 by a visionary partnership between the industrialist jamsetji nusserwanji tata, the maharaja of mysore, and the government of india. over the 109 years since its establishment, iisc has become the premier institute for advanced scientific and technological research and education in india. since its inception, the institute has laid a balanced emphasis on the pursuit of fundamental knowledge in science and engineering, and the application of its research findings for industrial and social benefit. during 2017–18, the institute initiated the practice of undergoing international peer academic reviews over a 5-year cycle. each year, a small team of invited international experts reviews a set of departments. the experts spend 3 to 4 days at the institute. during this period, they interact closely with the faculty and students of these departments and tour the facilities, aiming to assess the academic work against international benchmarks. iisc has topped the ministry of human resource development (mhrd), government of india’s nirf (national institutional ranking framework) rankings not only in the university’s category but also overall among all ranked institutions. times higher education has placed iisc at the 8th position in its small university rankings (that is, among universities with fewer than 5 ,000 students), at the 13th position in its ranking of universities in the emerging economies, and in the range 91–100 in its world reputation rankings. in the qs world university rankings, iisc is ranked 170. in the same ranking system, on the metric of citations per faculty, iisc is placed in second position. iisc publishes about 3,000 papers per year in scopus and web of science indexed journals and conferences and, each year, the institute awards around 400 phd degrees. about the iisc library jrd tata memorial library (https://www.library.iisc.ac.in), popularly known as the indian institute of science library, is one of the best science and technology libraries in india. started in 1911, as one of the first three departments in the institute, it has become a precious national resource center in the field of science and technology. the library receives annually a grant of 1012% of the total budget of the institute. the library spends about 95% of its budget toward periodical subscriptions, which is unparalleled in this part of the globe. with a collection of nearly 500,000 volumes of books, periodicals, technical reports and standards, the jrd tata memorial library is one of the finest in the country. currently, it subscribes to over 13,000 current periodicals. the library also maintains the iisc’s research publications repository, eprints@iisc (http://eprints.iisc.ac.in), and its theses and dissertations repository, etd@iisc (https://etd.iisc.ac.in). https://www.library.iisc.ac.in/

visvanathan 3 off-campus access to licensed online resources in a typical research library, licensed scholarly resources comprise research databases, electronic journals, e-books, standards, and more. a library licenses these resources through publishers/vendors. these license agreements limit access to the resources to the authorized users of an institute. in our case, authorized users include faculty members, enrolled students, current staff, contractual staff, and walk-in users to the library. seamless access to the licensed resources from on-campus sites is predominantly ip-address authenticated, which is a simple and efficient model for users physically located on the institute campus. these users expect a similar experience while accessing licensed online resources from off-campus locations. therefore, the challenge to the libraries is to ensure that such off-campus accesses are secure, seamless, and restricted to authorized users of an institute. libraries have been using various technologies including proxy servers, vpn servers, or single sign-on to facilitate seamless off-campus access to licensed resources. our institute has been using vpn technology to enable off-campus access to licensed online resources. a virtual private network (vpn) is a service offered by many organizations to its members to enable them to remotely connect to the organization’s private network. a vpn extends a private network across a public network and allows users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. applications running across a vpn may therefore benefit from the functionality, security, and management of the private network. encryption is common, although not an inherent, part of a vpn connection.3 in our institute, faculty members and students are provided access to the vpn service when their institute email address is created. users follow four steps to use a vpn client to get connected to the campus network: • install vpn client software on their computer system. cisco anyconnect (https://www.cisco.com/c/en/us/products/collateral/security/anyconnect-securemobility-client/at-a-glance-c45-578609.html) is one such software. • start the vpn client software every time there is a need to connect to the private network. • enter the address of the institute’s vpn server, and click connect in the anyconnect window. • log in to the vpn server using their institutional email credentials. an authorized user of the institute can use any of the ip authenticated network services, including the licensed online resources, after a successful login to the vpn server. the vpn technology has been serving the purpose well, but the service is, by default, available only to the institute’s faculty and students. other categories of employees such as project assistants, project associates, research assistants, post-doctoral fellows, and others, who constitute a good percentage of iisc staff, are provided vpn access on a case-by-case basis. during the covid-19 lockdown, the library received several enquiries about accessing the online resources from off-campus sites. realizing the importance of the situation, the library quickly assessed the various possibilities for facilitating seamless off-campus access to the subscribed online resources apart from the vpnbased access. federated access through shibboleth identity provider (idp) service emerged as a possible solution to facilitate seamless off-campus access to the entire institute community.

online resources | jayakanth, byrappa, and visvanathan 4 federated access federated access is a model for access control in which authentication and authorization are separated and handled by different parties. if a user wishes to access a resource controlled by a service provider (sp), the user logs in via an identity provider (idp). more complex forms of federated access involve the use of attributes (information about the user passed from the idp to the sp, which can be used to make access decisions) and can include extra services such as trust federations and discovery services (where the user selects which idp to use to connect to the sp). 4 examples of this federated access model include shibboleth and openathens. shibboleth is opensource software that offers single sign-on infrastructure. openathens is a commercial product delivered as a cloud-based solution. it supports many of the same standards as shibboleth. so, an institution could pay and join the openathens federation, which will provide technical support to set up, integrate, and operationalize federated access using openathens. we decided to go with shibboleth for the following reasons: • to avoid the recurring cost associated with the openathens solution. • the existence of a shibboleth-based infed federation in the country. infed manages the trust between the participating institutions and publishers (http://infed.inflibnet.ac.in/). • infed is part of the edugain inter-federation, which enables our users to gain access to the resources of federations of other countries. what is shibboleth? shibboleth is a standards-based, open-source software package for web single sign-on across or within organizational boundaries. it allows sites to make informed authorization decisions for individual access of protected online resources in a privacy-preserving manner. the shibboleth software implements widely used federated identity standards, principally the oasis security assertion markup language (saml), to provide a federated single sign-on and attribute exchange framework. a user authenticates with their organizational credentials, and the organization (or identity provider) passes the minimal identity information necessary to the service provider to enable an authorization decision. shibboleth also provides extended privacy functionality allowing a user and their home site to control the attributes released to each application (https://www.shibboleth.net/index/). shibboleth has two major components: (1) an identity provider (idp), and (2) a service provider (sp). the idp supplies required authorizations and attributes about the users to the service providers (for example, publishers). the service providers make use of the information about the users sent by the idp to make decisions on whether to allow or deny access to their resources. interaction between a shibboleth identity provider and service provider. when a user attempts to access licensed content on the service provider’s platform, the service provider generates an authentication request and then directs the request and the user to the user’s idp server. the idp prompts for the login credentials. in our setup, the idp server communicates the login credentials to the institute’s active directory (ad) using the secure lightweight directory access protocol (ldap).

is a directory service provided by microsoft. in a directory service, objects (such as a user, a group, a computer, a printer, or a shared folder) are arranged in a hierarchical manner facilitating easy access to the objects. organizations primarily use ad to perform authentication and authorization. once the authenticity of a user is verified, ad helps in determining if a user is authorized to use a specific resource or service. access is granted to a user only if the user checks out on both counts. the ad authenticates a user, and the response is sent back to the idp along with the required attributes. the idp then releases only the required set of attributes to the service provider. based on the idp attributes, which is nothing but a user’s entitlement, the sp grants access to the resource. figure 1 illustrates the functioning of the two components of shibboleth. figure 1. a shibboleth workflow involving a user, identity provider, and service provider. identity federation the interaction between a service provider and identity provider happens based on mutual trust. the trust is established by providing idp metadata as encrypted keys and the idp url that the sp uses to send and request information from the idp. the exchange of metadata between idp and sp can be informal if an institution licenses online resources from only a few publishers. however, research libraries license content from hundreds of sps. therefore, the role of federations is significant. in the absence of a federation, each identity provider and service provider must individually communicate with each other about their existence and configuration, as illustrated in figure 2. information technology and libraries june 2021 off-campus access to licensed online resources | jayakanth, byrappa, and visvanathan 6 figure 2. individual communication between idps and sps. a federation is merely a list of metadata entries aggregated from their member idps and their sps. our institute is a member of infed (information and library network access management federation). infed was established as a centralized agency to coordinate with member institutions in the process of implementing user authentication and access control mechanism across all member institutions. infed manages the trust relationship between the idps and sps (publishers) in india. therefore, individual idps that intend to facilitate access to subscribed online resources through shibboleth will share their metadata with infed. infed, in turn, will share the metadata of the idps with respective service providers, as illustrated in figure 3. other regions have their federations. for example, n the us, incommon (https://www.incommon.org/) serves as the federation, and in the uk, it is the uk access management federation (http://www.ukfederation.org.uk/). https://www.incommon.org/ http://www.ukfederation.org.uk/ information technology and libraries june 2021 off-campus access to licensed online resources | jayakanth, byrappa, and visvanathan 7 figure 3. role of a federation as a trust manager between idps and sps. how does one gain access to shibboleth-enabled resources? a federation manages the trust between identity providers and service providers. the sps enable shibboleth-based access to subscribed resources to the idps based on the metadata shared by a federation. once the sps allow access, users can access such resources by using the institutional login option via the athens/shibboleth link found on the service provider’s platform. alternatively, a library can create a simple html page listing all the shibboleth-enabled licensed resources, as shown in figure 4. information technology and libraries june 2021 off-campus access to licensed online resources | jayakanth, byrappa, and visvanathan 8 figure 4. partial screenshot of shibboleth-enabled resources of our institute. each of the links in figure 4 is a wayfless url. a wayfless url is specific to an institution (idp), and it enables users of that institution to gain federated access to a service or resource in a way that bypasses where are you from (wayf), or the institutional login (discovery service) steps on the sp’s platform. since the institutional login or the discovery service step can be confusing to end users, wayfless links to the resources will facilitate an improved end-user experience in accessing licensed resources. a user needs to follow a link from the list of resources. the link will take the user to the sp. the sp will redirect the user to the idp server for authentication. after successful authentication, the user will gain access to the resource. there are two ways to get a wayfless url to a service: (1) the service provider can share the url or (2) one can make use of a wayfless url generator service like wugen (https://wugen.ukfederation.org.uk/wugen/login.xhtml). https://wugen.ukfederation.org.uk/wugen/login.xhtml information technology and libraries june 2021

of the libraries in ensuring secure and seamless on-campus and off-campus access to subscribed online resources. there are other benefits of shibboleth-based sso: 1. it is open-source software that provides single sign-on infrastructure. 2. it enables organizations to use their existing user authentication mechanism to facilitate seamless access to licensed online resources. 3. being a single sign-on system, for the end users, it eliminates the need to have individual credentials for each online resource. 4. it uses security assertion mark-up language (saml) to securely transfer information about the process of authentication and authorization. 5. it is used by most of the publishers, who facilitate shibboleth-based access through shibboleth federations. 6. it requires a formal federation as a trusted interface between the institutions as an identity provider (idp) and publishers as service providers (sp) thereby ensuring the use of uniform standards and protocols while transmitting attributes of authorised users to publishers. inflibnet’s access management federation, infed, plays this role (https://parichay.inflibnet.ac.in/objectives.php). idp server configuration we installed the shibboleth idp software version 3.3.2 on a virtual machine on the azure platform. the vm system is configured with two virtual cpus, 4 gb of ram, 300 gib of os disk (standard hdd), and ubuntu linux os version 18.04.4 lts. coordination with the organization’s network support team is essential. the network support team handles the domain name service resolution of the idp server and facilitates the idp server to communicate with the organization’s active directory and to open non-standard communication ports on the idp server. shibboleth idp usage statistics the infed team has developed a beta version of the usage analysis tool called infedstat to analyse the use of federated access to gain access to licensed resources. we have implemented the tool on the idp server. figure 5 shows the redacted screenshot of the infedstat dashboard. it shows • date-wise usage details of logged-in users along with ip address, time logged in, and the publishers’ platforms accessed, • number of times the publishers’ platforms were accessed during a specific period, • number of times users logged in for a specific period, • unique users for a specific period, and • unique publishers accessed during a specific period. https://parichay.inflibnet.ac.in/objectives.php information technology and libraries june 2021 off-campus access to licensed online resources | jayakanth, byrappa, and visvanathan 10 figure 5. idp usage dashboard. conclusions the implementation of federated access to subscribed online resources has ensured that all the authorized users of the institute can access almost all the licensed resources from wherever they are. the counter 5 usage analysis of subscribed resources for the period of january 2020 to october 2020 indicates that usage of online resources has increased by nearly 20 percent over the last year for the same period. the enhanced use could be partly because of ease of accessing online resources facilitated by federated access. to assess the reasons for enhanced usage of online resources, the library is planning to conduct a survey to understand how convenient and useful federated access to online resources has been especially while being off campus. federated access through single sign-on is useful not just for accessing licensed online resources. a typical research library offers various other services to its users, including the institutional repository service, learning management system, online catalogue, etc. the library intends to integrate such services with sso, thereby freeing the end users from service-specific credentials. endnotes 1 thomas dowling, “we have outgrown ip authentication,” journal of electronic resources librarianship 32, no. 1 (2020): 39–46,

182 technical communications reports-library projects and activities ohio state university health sciences library uses autamated bookstack system the new health sciences library at ohio state university began serving students in may 1973 with some of the most advanced features in any library in the country. it contains an automated bookstack system to locate and file books, and is the fourth library in the country to have the system ( randtriever, manufactured by remington rand corp.), says jo ann johnson, director of the health sciences library. "the bookstack system will find and deliver a book via a conveyor belt in about a minute," miss johnson said. the chief advantages of the system are that it saves space and is speedy and accurate, she pointed out. "the book stacks in the new library take up about 15 percent of the total space while in most libraries the stacks take 40 to 60 percent of the space," miss johnson said. aisles in the stacks are narrow, about 15 inches, and the shelves rise through two stories of the library-twenty-two feet in all, she said. the library has a capacity of 175,000 volumes. the accuracy of the system will reduce the problem of misfiling. also, book theft should dwindle because the stacks will be closed to users, she said. the library is connected with the computerized circulation system of the university library, made up of a main library and twenty-three branch libraries. this circulation system is the first of its type in the country and permits library users to place telephone calls to learn titles and authors and to charge out books. other features of the modern library will include a computer-assisted instruction area to be completed later, and connections to medline, the international computerized information system of medical journals. miss johnson explained that the automated books tack system works like this: a library staff member sends instructions via a terminal to an electronic device in an aisle. the device travels on vertical and horizontal columns in the aisles. it picks out a small bin of books containing the requested one, then travels to the end of the aisle and places it on a conveyor belt. at the terminal, the staff member selects the requested book from the bin, usually containing about eight volumes, and sends the bin back for refiling. a glass window permits observation of the system. university of california, berkeley serials key word index the university of california, berkeley, general library has published a serials ke y word index to titles of 45,741 serials. the computer-produced index is the largest of a fairly new variety of key word indexes, covering titles of serials rather than articles. the 360/ assembler programs written by the library systems office include a number of innovations. berkeley serial records are stored in marc format, upper-lower case, capitalized by citation rather than catalog standards. the key word extract program ignores prepositions and conjunctions, etc. (which are not capitalized); treats certain multiword terms (la paz, united nations) as single words; prepares a librarystandard sorting key (with u.s. filing as united states, & filing as and, and distinction made between two types of hyphenation); and does no stop-list searching or other searching for excluded words. key lines are sorted by key word; all other processing is based on an alphabetic file of key words attached to main entries. thus, vocabulary control (forced interfiling of abbreviations, synonyms, cognates, etc.-not heavily used in this edition) is a fast, simple runtime operation, changing certain key words (on a single alphabetic pass) and generating "see" references. exclusion of low-content words is also a fast, simple runtime operation, done in the printing program, allowing excluded-word entries to print if the word occurs first in either title or author, and generating an explanatory note under each excluded key word. listings are main-entry, alphabetic under key word groups, with brief holdings, campus location, and call number where available. the key word appears in all capital letters within each entry, and redundant entries are collapsed-that is, if a wqrd appears more than once in an entry, each occurrence is capitalized, but the entry is only listed once under the key word. the first edition limits entries to 98 characters and holdings to 13 characters; the programs have since been revised to allow up to 193 character entries and up to 45 characters of holdings. both versions t echnical communications 183 of the programs retain as much runtime flexibility as possible, while maintaining extremely low running time. the first edition, including mostly nondocument currently-received titles, is photocomposed in a 6-point slab-serif type and published in three paperbound volumes. copies are available for $60 a set from systems office, main library, university of california, berkeley, ca 94720. walt crawford, university of california, berkeley programming and computers plea, a pli 1 efficiency analyzer pl/ 1 users find that the language offers infinite ways to invoke inefficient code. partial defense is provided by careful manual reading. another, and very plea ut~~ctio'! analysis pace stat£nent t~a~ counts foil main p~oceoorf t!slimeo offset 000)68 in load noouleo 'l 141 :' 69 ·r10 1 3 11 "\j ~ u •• ~~ 2 ii ,, u 4 »' i z1 l6j ---lt 25 9 35 14 u 5 ' ' f: hi ' ..

"members could specify a recycling period of from one to thirty-six weeks ... before unfulillled requests were returned." lowest price in lots of one-half million permalife cards was $8.01 per thousand. cpa's checked the system and found that all direct costs were included in 6.57¢ cost. no mention is made of the preexisting cataloging systems-<lne must assume cataloging each title and typing each card, with no use of either lc catalogs, proof sheets, or xerox. formatting costs for each card (their assumption of six cards per set) is 2.27¢ each; printing is .33¢ each; thus each card is 2.6¢, and each is 15.6¢ per set. they were unable to devise a procedure to implement a feature written into the program-the ability to delete a line on the lc card; thus they had to erase and type manually upon receipt of a set. shortest possible response time was ten days; the minimum average was two weeks for items found on the 186 journal of library automation vol. 6j 3 september 1973 first try (70 percent). hardware costs for the off-line system were not given, but they used four different computers in the osu center for their work. conclusion: on-line allows input by member libraries. listed monthly lease of hardware is $21,421.00 monthly; (actual costs were $16,317.00 due to various discounts). each terminal was $175.00 per month. operators can work at the rate of twelve titles per hour. seventy terminals at $175.00 per month hardware rental twenty thousand sets of permalife stock $12,250.00 21,421.00 961.00 $34,632.00 $34,632.00 divided by 20,000 titles per month-$1.73 per card set. personnel layoffs through attrition did not compensate for the burden of the online system. included in the cost was the rental of all hardware, cathode ray tube terminals, and permalife stock. this was felt justified, because there is no other tangible outlet to the system; when interlibrary loan is included in the results, then costs will go down roughly 10 percent. not included in the cost of $1.73 per set were: 1. salaries and wages of center personnel 2. building rental and other costs 3. programming costs 4. keypunching cost for the card input 5. rental of phone lines for the terminals 6. cost of marc tapes. omitted cost/income factor: annual dues charge for participation in oclc. (prepared by daniel bischel, university of puget sound library) to the editor: as the article about which mr. taylor has written to you states, the principal substantive objective of the oclc systern is to increase availability of library resources to users of participating libraries. products of the present subsystem are an on-line union catalog currently containing over one and a quarter million location listings as well as the catalog of each library from initial time of participation (some libraries are retrospectively converting their shelflists and one has completed the task), and catalog cards in :final form alphabetized for filing in specific catalogs in specific libraries. cataloging done on the system produces the union catalog and catalog cards. libraries use the system for searching ( dartmouth has reduced its searching staff from three to one fulltime position and seven to five parttime), for obtaining information, for ordering, for book selection (an expensive work with little expected use is not purchased if a nearby library already possesses it), for locating works for interlibrary loan, and for cataloging (ohio university has reduced eight positions from its budget while increasing cataloging from 25,000 to 39,000 in a year) . about 70 percent of the time, cataloging data is found in the system. an ohio library pays for all types of use of the system on the basis of the number of records used for the first time for catalog production that are not records input by the cataloging library; there is no charge if the cataloging library input the record. the estimated cost for the present year for system use by an ohio library is $2.02 per record used for the first time and not input by the library; this fe e pays for the terminals, telephone lines, computer, and all other oclc expenditures except grant-supported research and development. a library in a region outside of ohio pays a slightly larger fee because of increased telephone charges. if a region elects to pay its own telephone charges and purchase its own terminals, the charge per first-time use is 87.5¢. the only other payment a library makes is 3.4¢ per catalog card. frederick g. kilgour exeetltive director ohio college library center columbus, ohio improving independent student navigation of complex educational web sites: an analysis of two navigation design changes in libguides kate a. pittsley and sara memmott information technology and libraries | se ptember 2012 52 abstract can the navigation of complex research websites be improved so that users more often find their way without intermediation or instruction? librarians at eastern michigan university discovered both anecdotally and by looking at patterns in usage statistics that some students were not recognizing navigational elements on web-based research guides, and so were not always accessing secondary pages of the guides. in this study, two types of navigation improvements were applied to separate sets of online guides. usage patterns from before and after the changes were analyzed. both sets of experimental guides showed an increase in use of secondary guide pages after the changes were applied whereas a comparison group with no navigation changes showed no significant change in usage patterns. in this case, both duplicate menu links and improvements to tab design appeared to improve independent student navigation of complex research sites. introduction anecdotal evidence led librarians at eastern michigan university (emu) to investigate possible navigation issues related to the libguides platform. anecdotal evidence included (1) incidents of emu librarians not immediately recognizing the tab navigation when looking at implementations of the libguides platform on other university sites during the initial purchase evaluation, (2) multiple encounters with students at the reference desk who did not notice the tab navigation, and (3) a specific case involving use of a guide with an online course. the case investigation started with a complaint from a professor that graduate students in her online course were suddenly using far fewer resources than students in the same course during previous semesters. the students in that semester’s section relied heavily—often solely— on one database, while most students during previous semesters had used multiple research sources. this course has always relied on a research guide prepared by the liaison librarian, the selection of resources provided had not changed significantly between the semesters, and the assignment had not changed. furthermore, the same professor taught the course and did not alter her recommendation to the students to use the resources on the research guide. what had changed between the semesters was the platform used to present research guides. the library had just migrated from a simple one-page format for research guides to the more flexible multipage format offered by the libguides platform. only a few resources were listed on the first kate a. pittsley (kpittsle@emich.edu) is an assistant professor and business information librarian and sara memmott (smemmott@emich.edu) is an instructor and emerging technologies librarian at eastern michigan university, ypsilanti, michigan. improving independent student navigation of complex educational websites | pittsley and memmott 53 libguides page of the guide used for the course. only one of these resources was a subscription database, and that database was the one that current students were using to the exclusion of many other useful sources. after speaking with the professor, the liaison librarian also worked one-on-one with a student in the course. the student confirmed that she had not noticed the tab navigation and so was unaware of the numerous resources offered on subsequent pages. the professor then sent a message to all students in the course explaining the tab navigation. subsequently the professor reported that students in the course used a much wider range of sources in assignments. statistical evidence of the problem a look at statistics on guide use for fall 2010 showed that on almost all guides the first pages of guides were the most heavily used. as the usual entry point, it wasn’t surprising that the first pages would receive the most use; however, on many multipage guides, the difference in use between the first page and all secondary pages was dramatic. that users missed the tab navigation and so did not realize additional guide pages existed seemed like a possible explanation for this usage pattern. librarians felt strongly that most users should be able to navigate guides without direct instruction in their use, and they were concerned by the evidence that indicated problems with the guide navigation. was there something that could be done to improve independent student navigation in libguides? two types of design changes to navigation were considered. to test the changes, each navigation change was applied to separate sets of guides. usage patterns were then compared for those guides before and after changes were made. the investigators also looked at usage patterns over the same period for a comparison group to which no navigation changes had been made. literature review navigation in libguides and pathfinders the authors reviewed numerous articles related to libguides or pathfinders generally, but found few that mention navigation issues. they then turned to studies of website navigation in general. in an early article on the transition to web-based library guides, cooper noted that “computer screens do not allow viewers to visualize as much information simultaneously as do print guides, and consequently the need for uncomplicated, easily understood design is even greater.”1 four university libraries’ usability studies of the libguides platform specifically address navigation issues. university of michigan librarians dubicki et al. found that “tabs are recognizable and meaningful—users understood the function of the tabs.”2 the michigan study then focused on the use of meaningful language for tab labels. however, at the latrobe university library (australia), corbin and karasmanis found a consistent pattern of students not recognizing the navigation tabs, and so recommended providing additional navigation links elsewhere on the page.3 at the university of washington, hungerford et al. found students did not immediately recognize the tab navigation: information technology and libraries | se ptember 2012 54 during testing it was observed that users frequently did not notice a guide’s tabs right away as a navigational option. users’ eyes were drawn to the top middle of the page first and would focus on content there, especially if there was actionable content, such as links to other pages or resources.4 the solution at the university of washington was to require that all guides have a main page navigation area (libguides “box”) with a menu of links to the tabbed pages. after a usability study, mit libraries also recommended use of a duplicate navigation menu on the first page, stating in mit libraries staff guidelines for creating libguides to “make sure to link to the tabs somewhere on the main page” as “users don’t always see the tabs, so providing alternate navigation helps.”5 navigation palmer mentions navigation as one of the factors most significantly associated with website success as measured by user satisfaction, likelihood to use a site again, and use frequency.6 however, effective navigation may be difficult to achieve. nielsen found in numerous studies that “users look straight at the content and ignore the navigation areas when they scan a new page.”7 in a presentation on the top ten mistakes in web design, human–computer interaction scholar tullis included “awkward or confusing navigation.”8 the following review of the literature on website navigation design is limited to studies of navigation models that use browsing via menus, tabs, and menu bars. the navigation problem seen in libguides is far from unique. usability studies for other information-rich websites demonstrate similar problems with users not recognizing navigation tabs or menu bars similar to those used in libguides. in 2001, mcgillis and toms investigated the usability of a library website with a horizontal navigation bar at the top of the page, a design similar to the single row of libguides tabs. this study found that users either did not see the navigation bar or did not realize it could be clicked.9 in multiple usability studies, u.s. census bureau researchers found similar problems with navigation bars on government websites. in 2009, olmsted-hawala et al. reported that study participants did not use the top-navigation bar on the census bureau’s business and industry website.10 the next year, chen et al. again reported problems with top-navigation bar use on the governments division public website, explaining that the “top-navigation bar blends into the header, leading participants to skip over the tabs and move directly to the main content. this is a recurring issue the usability laboratory has identified with many web sites.”11 one possible explanation for user neglect of tabs and navigation bars may be a phenomenon termed “banner blindness.” as early as 1999, benway provided in-depth analysis of this problem. in his thesis, he uses the word “banner” not just for banner ads, but also for banners that consist of horizontal graphic buttons similar to the libguides tab design. benway’s experiments show that an attempt to make important items visually prominent may have the opposite effect— that “the visual distinctiveness may actually make important items seem unimportant.” benway follows with two recommendations: (1) that “any method that is created to make something stand out should be carefully tested with users who are specifically looking for that content to ensure that it does not cause banner blindness,” and (2) that “any item visually distinguished on a page should be duplicated within a collection of links or other navigation areas of the page. that way, if searchers ignore the large salient item, they can still find what they need through basic navigation.”12 improving independent student navigation of complex educational websites | pittsley and memmott 55 in 2005, tullis cited multiple studies that showed that users found information faster or more effectively by using a simple table of contents than by using other navigation forms, including tabbased navigation.13 yet in 2011, nicolson et al. found that “participants rarely used table of contents; and often appeared not to notice them.”14 yelinek et al. pointed to a practical problem in using content menus on libguides pages: since libguides pages can be copied or mirrored on other guides, guide authors must be cognizant that such menus could cause problems with incorrect or confusing navigational links on copied or mirrored pages.15 success can also depend on the location of navigational elements, although researchers disagree on effects of location. in addition, user expectations of where to look for navigation elements may change over time along with changes in web conventions. in 2001, bernard studied user expectations as to where common web functions would be located on the screen layout. he found that “most participants expected the links to web pages within a website to be almost exclusively located in the upper-left side of a web page, which conforms to the current convention of placing links on [the] left side.”16 in 2004, pratt et al. found that users were equally effective using horizontal or vertical navigation menus, but when given a choice more users chose to use vertical navigation.17 also in 2004, mccarthy et al. performed an eye-tracking study, which showed faster search times when sites conformed to the expected left navigation menu and a user bias toward searching the middle of the screen; but it also found that the initial effect of menu position diminished with repeated use of a site.18 nonetheless, jones found that by 2006 most corporate webpages used “horizontally aligned primary navigation using buttons, tabs, or other formatted text.”19 in 2008, cooke found that users looked equally at left, top, and center menus; however, when “a visually prominent navigation menu populated the center of the web page, participants were more likely to direct their search in this location.”20 wroblewski describes how tab navigation was first popularized by amazon.21 burrell and sodan investigated user preferences for six navigation styles and found that users clearly preferred tab navigation “because it is most easily understood and learned.”22 in the often-cited web design manual don’t make me think, krug also recommends tabs: “tabs are one of the very few cases where using a physical metaphor in a user interface actually works.”23 krug recommends that tabs be carefully designed to resemble file folder tabs. they should “create the visual illusion that the active tab is in front of the other tabs . . . the active tab needs to be a different color or contrasting shade [than the other tabs] and it has to physically connect with the space below it. this is what makes the active tab ‘pop’ to the front.”24 an often-cited u.s. department of health and human services manual on research-based web design addresses principles of good tab design, stating that tabs should be located near the top of the page and should “look like clickable versions of real-world tabs. real-world tabs are those that resemble the ones found in a file drawer.”25 nielsen provides similar guidelines for tab design, which include that the selected tab should be highlighted, the current tab should be connected to the content area (just like a physical tab), and that one should use only one row of tabs.26 more recently, cronin highlighted examples of good tab design that effectively use elements such as rounded tab corners, space between tabs, and an obvious design for the active tab that visually connects the tab to the area beneath it.27 christie also provides best practices for tab design that include consistent use of only one row of tabs, use of a prominent color for the active tab and a single information technology and libraries | se ptember 2012 56 background color for unselected tabs, changing the font color on the active tab, and use of rounded corners to enhance the file-folder-tab metaphor.28 two articles mention that the complexity of a site can be a factor in navigation success. mccarthy et al. found that search times are significantly affected by site complexity and recommended finding ways to balance the provision of numerous user options with simplifying the site so that users can find their way.29 little specifically suggests reducing the amount of extraneous information on libguides pages in her article, which applies cognitive load theory to use of library research guides.30 in sum, effective navigation is difficult to achieve. however, navigation design can be improved by considering the purpose of the site, user expectations, common conventions, best practices, the possibility that intuitive ideas for design may not perform as expected (e.g., banner blindness), the site’s complexity, and more. research question and method could design changes improve independent student use of libguides tab navigation? the literature reviewed above suggested two likely design changes to test: adding additional navigation links in the body of the page and improving the tab design. testing these design changes on selected guides would allow the emu library to assess the impact before implement changes on all library research guides. for this experiment, each type of navigation change was applied to separate subsets of guides; a subset of similar guides was selected as a comparison group; and usage patterns were analyzed for similar periods before and after changes were made. navigation design changes were made to fourteen subject guides related to business. the business subject guides were divided into two experimental groups of seven guides. in group a, a table of contents box with navigation links was added to the front page of each guide, and in group b, the navigation tabs were altered in appearance. no navigation changes were made to comparison group c. class specific guides were excluded from the experiment, as in many cases the business librarian would have instructed students in the use of tabs on class guides. changes were made at the beginning of the winter 2011 semester so that an entire semester’s data could be collected and compared to the previous semester’s usage patterns. the design for group a was similar to the university of washington implementation of a “what’s in the guide” box on guide homepages that repeated the tab navigation links.31 for guides in group a, a table of contents box was placed on the guide homepages. it contained a simple list of links to the secondary pages of the guides, using the same labels as on the navigation tabs. the table of contents box used a larger font size than other body text and was given an outline color that contrasted with the outline color used on other boxes and matched the navigation tab color to create visual cues that this box had a different function from the other boxes on the page (navigation). the table of contents box was placed alongside other content on the guide homepages so users could still see the most relevant resources immediately. figure 1 shows a guide containing a table of contents box. improving independent student navigation of complex educational websites | pittsley and memmott 57 figure 1. group a guide with content menu box labeled “guide sections” the design change for group b focused on the navigation tabs. libguides tabs exhibit some of the properties of good tab design, such as allowing for rounded corners and contrasting colors for the selected tabs. other aspects are not ideal, such as the line that separates the active tab from the page body.32 in the emu library’s initial libguides implementation, the option for tabs with rounded corners was used to resemble the design of manila file folders and increase the association with the file-folder metaphor. possibilities for further design adaptation on the experimental guides were somewhat limited because these changes needed to be applied to the tabs of just a selected set of guides. the investigators theorized that increasing the height of the tabs might make them more closely resemble paper file folder tabs. increasing the height would also increase the area of the tabs, and the larger size might also make the tabs more noticeable. this option was simple to implement on the guides in group b by adding html break tags, <br />, to the tab text. taller tabs also provided more room for text on the tabs. tabs in libguides will expand in width to fit the text label used, and if the tabs on a guide require more space on the page, they will be displayed in multiple rows. multiple rows of tabs are visually confusing and break the tabs metaphor, decreasing their usefulness for navigation.33 the emu library’s best practices for research guides already encouraged limiting tabs to one row. adding height to tabs allowed for clearer text labels on some guides without expanding the tab display beyond a single row. figure 2 shows a guide containing the altered taller tabs. information technology and libraries | se ptember 2012 58 figure 2. group b guide with tabs redesigned to look more like file folder tabs while variations in content and usage of library guides did not allow for a true control group, other social science subject guides were selected as a comparison group. social science subject guides were excluded from the comparison group if they had very low guide usage during the fall 2010 semester (fewer than thirty uses), or if they had fewer than three tabs, making them structurally dissimilar to the business guides. this left a group of sixteen comparison guides. no changes were made to the navigation design of these guides during the test period. the business guides—which the authors had permission to experiment with—tend to be longer and have more pages than other guides. on average, the experimental guides had more pages per guide than the comparison guides; guides in groups a and b averaged nine pages per guide, and comparison guides averaged five pages per guide. guides with more pages will tend to have a higher percentage of hits on secondary pages because there are more pages available to users. however, the authors intended to measure the change in usage patterns with each guide measured against itself in different periods, and the number of pages in each guide did not change from semester to semester. data collection and results libguides provides monthly usage statistics that include the total hits on each guide and the number of hits on each page of a guide. use of secondary pages of the guides was measured by calculating the proportion of hits to each guide that occurred on secondary pages. data for the fall 2010 semester (september through december 2010) was used to measure usage patterns before navigation changes were made to the experimental guides. data for the winter 2011 semester (january through april 2011) was used to measure usage patterns after navigation changes were made. each would represent a full semester’s use at similar enrollment levels with many of the same courses and assignments. usage patterns for the comparison guides were also examined for these periods. improving independent student navigation of complex educational websites | pittsley and memmott 59 as shown in figures 3 and 4, in both group a and group b, the percentage of hits on secondary pages increased in five guides and decreased in two guides. figure 3. group a: change in secondary page usage with content menus added for winter 2011 figure 4. group b: change in secondary page usage with new tab design for winter 2011 both groups of experimental guides showed an increase in use of secondary guide pages after the design changes were made. the median usage score was calculated for each group. group a, with the added menu links, showed an increase of 10.3 points in the median percentage of guide hits on secondary pages. group b, with redesigned tabs, showed an increase of 10.4 points in the median percentage of guide hits on secondary pages. within the

all experimental guides and all comparison guides, the change in use of secondary pages was found to be statistically significant. the average change in use of secondary pages for all experimental guides (groups a and b) was .07871, and the average for all comparison guides (group c) was -.02550. a t test showed that this difference was significant at the p < . 05 level (p = .032). study limitations in some (possibly many) cases, the first page of the guide provides all necessary sources and advice for an assignment. we measured actual use of secondary pages, but were unable to measure recognition of navigation elements where the student did not use the secondary pages because they had no need for additional resources. because it wasn’t possible to control use of the guides during the periods studied, it is possible that factors other than the design changes contributed to the pattern of hits. though subject guides rather than class guides were used to limit the influence of instruction in the use of guides, it wasn’t possible to determine with certainty if other faculty members instructed a significant number of students in the use of particular guides during the periods examined. the comparison group was slightly dissimilar in that they had fewer pages than the experimental guides; however, the number of pages on a guide did not correlate with a change in percentage of hits on secondary pages from one semester to the next. application of findings when presented with the study results, the full library faculty at emu expressed interest in using both design changes across all library research guides. the change to tab design—which is easiest to implement—has been made to all subject guides. some librarians also chose to add content menus to selected guides. since the complexity of research guides is also a factor in successful navigation,35 a recent libguides enhancement was used to move elements from the header area to the bottom of the guides. the elements moved out of the header included the date of last update, guide url, print option, and rss updates. the investigators hypothesize that the reduced complexity of the header may help in recognizing the tab navigation. although convinced that the experimental changes made a difference to independent student navigation in research guides, the authors hope to find further ways to strengthen independent navigation. vendor design changes to enhance the tab metaphor, such as creating a more visible connection between the active tab and page, might also improve navigation.36 information technology and libraries | se ptember 2012 62 conclusion designing navigation for complex sites, such as library research guides, is likely to be an ongoing challenge. this study suggests that thoughtful design changes can improve navigation. in this case, both duplicate menu links and improvements to tab design improved independent student navigation of complex research sites. references and notes 1. eric a. cooper, “library guides on the web: traditional tenets and internal issues,” computers in libraries 17, no. 9 (1997): 52. 2. barbara dubicki beaton et al.,

from research in software engineering. wasted effort and poor interoperability can therefore ensue, raising the costs of dls and jeopardizing the fluidity of information assets in the future. in addition, there is a need for modeling services and data structures as highlighted in the “digital library reference model” proposed by the delos eu network of excellence (also called the “delos manifesto”);2 in fact, the distribution of dl services over digital networks, typically accessed through web browsers or dedicated clients, makes the whole theme of interaction between users important, for both individual usage and remote collaboration. designing and modeling such interactions call for considerations pertaining to the fields of human– computer interaction (hci) and computer-supported cooperative work (cscw). as an example, scenariobased or activity-based approaches developed in the hci area can be exploited in dl design. to meet these needs we developed cradle (cooperative-relational approach to digital library environments),3 a metamodel-based digital library management system (dlms) supporting collaboration in the design, development, and use of dls, exploiting patterns emerging from previous projects. the entities of the cradle metamodel allow the specification of collections, structures, services, and communities of users (called “societies” in cradle) and partially reflect the delos manifesto. the metamodel entities are based on existing dl taxonomies, such as those proposed by fox and marchionini,4 gonçalves et al.,5 or in the delos manifesto, so as to leverage available tools and knowledge. designers of dls can exploit the domain-specific visual language (dvsl) available in the cradle environment—where familiar entities extracted from the referred taxonomies are represented graphically—to model data structures, interfaces and services offered to the final users. the visual model is then processed and transformed, exploiting suitable templates, toward a set of specific languages for describing interfaces and services. the results are finally transformed into platformindependent (java) code for specific dl applications. cradle supports the basic functionalities of a dl through interfaces and service templates for managing, browsing, searching, and updating. these can be further specialized to deploy advanced functionalities as defined by designers through the entities of the proposed visual the design and development of a digital library involves different stakeholders, such as: information architects, librarians, and domain experts, who need to agree on a common language to describe, discuss, and negotiate the services the library has to offer. to this end, high-level, language-neutral models have to be devised. metamodeling techniques favor the definition of domainspecific visual languages through which stakeholders can share their views and directly manipulate representations of the domain entities. this paper describes cradle (cooperative-relational approach to digital library environments), a metamodel-based framework and visual language for the definition of notions and services related to the development of digital libraries. a collection of tools allows the automatic generation of several services, defined with the cradle visual language, and of the graphical user interfaces providing access to them for the final user. the effectiveness of the approach is illustrated by presenting digital libraries generated with cradle, while the cradle environment has been evaluated by using the cognitive dimensions framework. d igital libraries (dls) are rapidly becoming a preferred source for information and documentation. both at research and industry levels, dls are the most referenced sources, as testified by the popularity of google books, google video, ieee explore, and the acm portal. nevertheless, no general model is uniformly accepted for such systems. only few examples of modeling languages for developing dls are available,1 and there is a general lack of systems for designing and developing dls. this is even more unfortunate because different stakeholders are interested in the design and development of a dl, such as information architects, to librarians, to software engineers, to experts of the specific domain served by the dl. these categories may have contrasting objectives and views when deploying a dl: librarians are able to deal with faceted categories of documents, taxonomies, and document classification; software engineers usually concentrate on services and code development; information architects favor effectiveness of retrieval; and domain experts are interested in directly referring to the content of interest without going through technical jargon. designers of dls are most often library technical staff with little to no formal training in software engineering, or computer scientists with little background in the research findings of hypertext information retrieval. thus dl systems are usually built from scratch using specialized architectures that do not benefit alessio malizia

digital libraries: a model-driven approach 172 information technology and libraries | december 2010 a formal foundation for digital libraries, called 5s, based on the concepts of streams, (data) structures, (resource) spaces, scenarios, and societies. while being evidence of a good modeling endeavor, the approach does not specify formally how to derive a system implementation from the model. the new generation of dl systems will be highly distributed, providing adaptive and interoperable behaviour by adjusting their structure dynamically, in order to act in dynamic environments (e.g., interfacing with the physical world).13 to manage such large and complex systems, a systematic engineering approach is required, typically one that includes modeling as an essential design activity where the availability of such domain-specific concepts as first-class elements in dl models will make application specification easier.14 while most of the disciplines related to dls—e.g., databases,15 information retrieval,16 and hypertext and multimedia17—have underlying formal models that have properly steered them, little is available to formalize dls per se. wang described the structure of a dl system as a domain-specific database together with a user interface for querying the records stored in the database.18 castelli et al. present an approach involving multidimensional query languages for searching information in dl systems that is based on first-order logic.19 these works model metadata specifications and thus are the main examples of system formalization in dl environments. cognitive models for information retrieval, as used for example by oddy et al.,20 focus on users’ information-seeking behavior (i.e., formation, nature, and properties of a users’ information need) and on how information retrieval systems are used in operational environments. other approaches based on models and languages for describing the entities involved in a dl are the digital library definition language,21 the dspace data model22 (with the definitions of communities and workflow models), the metis workflow framework,23 and the fedora structoid approach.24 e/r approaches are frequently used for modeling database management system (dbms) applications,25 but as e/r diagrams only model the static structure of a dbms, they generally do not deal deeply with dynamic aspects. temporal extensions add dynamic aspects to the e/r approach, but most of them are not object-oriented.26 the advent of object-oriented technology calls for approaches and tools to information system design resulting in object-oriented systems. these considerations drove research toward modeling approaches as supported by uml.27 however, since the uml metamodel is not yet widespread in the dl community, we adopted the e/r formalism and complemented it with the specification of the dynamics made available through the user interface, as described by malizia et al.28 using the metamodel, we have defined a dsvl, including basic entities and language. cradle is based on the entity-relationship (e/r) formalism, which is powerful and general enough to describe dl models and is supported by many tools as a metamodeling language. moreover, we observed that users and designers involved in the dl environment, but not coming from a software engineering background, may not be familiar with advanced formalism like unified modeling language (uml), but they usually have basic notions on database management systems, where e/r is largely employed. ■■ literature review dls are complex information systems involving technologies and features from different areas, such as library and information systems, information retrieval, and hci. this interdisciplinary nature is well reflected in the various definitions of dls present in the literature. as far back as 1965, licklider envisaged collections of digital versions of scanned documents accessible via interconnected computers.6 more recently, levy and marshall described dls as sets of collections of documents, together with digital resources, accessible by users in a distributed context.7 to manage the amount of information stored in such systems, they proposed some sort of user-assisting software agent. other definitions include not only printed documents, but multimedia resources in general.8 however different the definitions may be, they all include the presence of collections of resources, their organization in structured repositories, and their availability to remote users through networks (as discussed by morgan).9 recent efforts toward standardization have been taken by public and private organizations. for example, a delphi study identified four main ingredients: an organized collection of resources, mechanisms for browsing and searching, a distributed networked environment, and a set of objectified services.10 the president’s information technology advisory committee (pitac) panel on digital libraries sees dls as the networked collections of digital text, documents, images, sounds, scientific data, and software that make up the core of today’s internet and of tomorrow’s universally accessible digital repositories of all human knowledge.11 when considering dls in the context of distributed dl environments, only few papers have been produced, contrasting with the huge bibliography on dls in general. the dl group at the universidad de las américas puebla in mexico introduced the concept of personal and group spaces, relevant to the cscw domain, in the dl system context.12 users can share information stored in their personal spaces or share agents, thus allowing other users to perform the same search on the document collections in the dl. the cited text by gonçalves et al. gives generating collaborative systems for digital libraries | malizia, bottoni, and levialdi 173 education as discussed by wattenberg or zia.33 in the nsdl program, a new generation of services has been developed that includes support for teaching and learning; this means also considering users’ activities or scenarios and not only information access. services for implementing personal content delivery and sharing, or managing digital resources and modeling collaboration, are examples of tools introduced during this program. the virtual reference desk (vrd) is emerging as an interactive service based on dls. with vrd, users can take advantage of domain experts’ knowledge and librarians’ experience to locate information. for example, the u.s. library of congress ask a librarian service acts as a vrd for users who want help in searching information categories or to interact with expert librarians to search for a specific topic.34 the interactive and collaborative aspects of activities taking place within dls facilitate the development of user communities. social networking, work practices, and content sharing are all features that influence the technology and its use. following borgmann,35 lynch sees the future of dls not in broad services but in supporting and facilitating “customization by community,” i.e., services tailored for domain-specific work practices.36 we also examined the research agenda on systemoriented issues in dls and the delos manifesto.37 the agenda abstracts the dl life cycle, identifying five main areas, and proposes key research problems. in particular we tackle activities such as formal modeling of dls and their communities and developing frameworks coherent with such models. at the architectural level, one point of interest is to support heterogeneous and distributed systems, in particular networked dls and services.38 for interoperability, one of the issues is how to support and interoperate with different metadata models and standards to allow distributed cataloguing and indexing, as in the open archive initiative (oai).39 finally, we are interested in the service level of the research agenda and more precisely in web services and workflow management as crucial features when including communities and designing dls for use over networks and for sharing content. as a result of this analysis, the cradle framework features the following: ■■ a visual language to help users and designers when visual modeling their specific dl (without knowing any technical detail apart from learning how to use a visual environment providing diagrams representations of domain specific elements) ■■ an environment integrating visual modeling and code generation instead of simply providing an integrated architecture that does not hide technical details ■■ interface generation for dealing with different users relationships for modeling dl-related scenarios and activities. the need for the integration of multiple languages has also been indicated as a key aspect of the dsvl approach.29 in fact, complex domains like dls typically consist of multiple subdomains, each of which may require its own particular language. in the current implementation, the definition of dsvls exploits the metamodeling facilities of atom3, based on graph-grammars.30 atom3 has been typically used for simulation and model transformation, but we adopt it here as a tool for system generation. ■■ requirements for modeling digital libraries we follow the delos manifesto by considering a dl as an organization (possibly virtual and distributed) for managing collections of digital documents (digital contents in general) and preserving their images on storage. a dl offers contextual services to communities of users, a certain quality of service, and the ability to apply specific policies. in cradle we leave the definition of quality of service to the service-oriented architecture standards we employ and partially model the applicable policy, but we focus here on crucial interactivity aspects needed to make dls usable by different communities of users. in particular, we model interactive activities and services based on librarians’ experiences in face-to-face communication with users, or designing exchange and integration procedures for communicating between institutions and managing shared resources. while librarians are usually interested in modeling metadata across dls, software engineers aim at providing multiple tools for implementing services,31 such as indexing, querying, semantics,32 etc. therefore we provide a visual model useful for librarians and information architects to mimic the design phases they usually perform. moreover, by supporting component services, we help software engineers to specify and add services on demand to dl environments. to this end, we use a service component model. by sharing a common language, users from different categories can communicate to design a dl system while concentrating on their own tasks (services development and design for software engineers and dl design for librarians and information architects). users are modeled according to the delos manifesto as dl end-users (subdivided into content creators, content consumers, and librarians), dl designers (librarians and information architects), dl system administrators (typically librarians), and dl application developers (software engineers). several activities have been started on modeling domain specific dls. as an example, the u.s. national science digital library (nsdl) program promotes educational dls and services for basic and advanced science 174 information technology and libraries | december 2010 ■■ how that information is structured and organized (structural model) ■■ the behavior of the dl (service model) and the different societies of actors ■■ groups of services acting together to carry out the dl behavior (societal model) figure 1 depicts the design approach supported by cradle architecture, namely, modeling the society of actors and services interacting in the domain-specific scenarios and describing the documents and metadata structure included with the library by defining a visual model for all these entities. the dl is built using a collection of stock parts and configurable components that provide the infrastructure for the new dl. this infrastructure includes the classes of objects and relationships that make up the dl, and processing tools to create and load the actual library collection from raw documents, as well as services for searching, browsing, and collection maintenance. finally, the code generation module generates tailored dl services code stubs by composing and specializing components from the component pool. initially, a dl designer is responsible for formalizing (starting from an analysis of the dl requirements and characteristics) a conceptual description of the dl using metamodel concepts. model specifications are then fed into a dl generator (written in python for atom3), to produce a dl tailored suitable for specific platforms and requirements. after these design phases, cradle generates the code for the user interface and the parts of code corresponding to services and actors interacting in the described society. a set of templates for code generation and designers ■■ flexible metadata definitions ■■ a set of interactive integrated tools for user activities with the generated dl system to sum up, cradle is a dlms aimed at supporting all the users involved in the development of a dl system and providing interfaces, data modeling, and services for user-driven generation of specific dls. although cradle does not yet satisfy all requirements for a generic dl system, it addresses issues focused on developing interactive dl systems, stressing interfaces and communication between users. nevertheless, we employed standards when possible to leave it open for further specification or enhancements from the dl user community. extensive use of xml-based languages allows us to change document information depending on implemented recognition algorithms so that expert users can easily model their dl by selecting the best recognition and indexing algorithms. cradle evolves from the jdan (java-based environment for document applications on networks) platform, which managed both document images and forms on the basis of a component architecture.40 jdan was based on xml technologies, and its modularity allowed its integration in service-based and grid-based scenarios. it supported template code generation and modeling, but it required the designer to write xml specifications and edit xml schema files in order to model the dl document types and services, thus requiring technical knowledge that should be avoided to let users concentrate on their specific domains. ■■ modeling digital library systems the cradle framework shows a unique combination of features: it is based on a formal model, exploits a set of domain-specific languages, and provides automatic code generation. moreover, fundamental roles are played by the concepts of society and collaboration.41 cradle generates code from tools built after modeling a dl (according to the rules defined by the proposed metamodel) and performs automatic transformation and mapping from model to code to generate software tools for a given dl model. the specification of a dl in cradle encompasses four complementary dimensions: ■■ multimedia information supported by the dl (collection model) figure 1. cradle architecture generating collaborative systems for digital libraries | malizia, bottoni, and levialdi 175 socioeconomic, and environment dimensions. we now show in detail the entities and relations in the derived metamodel, shown in figure 2. actor entities actors are the users of dls. actors interact with the dl through services (interfaces) that are (or can be) affected by the actors preferences and messages (raised events). in the cradle metamodel, an actor is an entity with a behavior that may concurrently generate events. communications with other actors may occur synchronously or asynchronously. actors can relate through services to shape a digital community, i.e., the basis of a dl society. in fact, communities of students, readers, or librarians interact with and through dls, generally following predefined scenarios. as an example, societies can behave as query generator services (from the point of view of the library) and as teaching, learning, and working services (from the point of view of other humans and organizations). communication between actors within the same or different societies occur through message exchange. to operate, societies need shared data structures and message protocols, enacted by sending structured sequences of queries and retrieving collections of results. the actor entity includes three attributes: 1. role identifies which role is played by the actor within the dl society. examples of specific human roles include authors, publishers, editors, maintainers, developers, and the library staff. examples of nonhuman actors include computers, printers, telecommunication devices, software agents, and digital resources in general. 2. status is an enumeration of possible statuses for the actor: i. none (default value) ii. active (present in the model and actively generating events) iii. inactive (present in the model but not generating events) iv. sleeping (present in the model and awaiting for a response to a raised event) 3. events describes a list of events that can be raised by the actor or received as a response message from a service. examples of events are borrow, reserve, return, etc. events triggered from digital resources include store, trash, and transfer. examples of response events are found, not found, updated, etc. have been built for typical services of a dl environment. to improve acceptability and interoperability, cradle adopts standard specification sublanguages for representing dl concepts. most of the cradle model primitives are defined as xml elements, possibly enclosing other sublanguages to help define dl concepts. in more detail, mime types constitute the basis for encoding elements of a collection. the xml user interface language (xul)42 is used to represent appearance and visual interfaces, and xdoclet is used in the libgen code generation module, as shown in figure 1.43 ■■ the cradle metamodel in the cradle formalism, the specification of a dl includes a collection model describing the maintained multimedia documents, a structural model of information organization, a service model for the dl behavior, and a societal model describing the societies of actors and groups of services acting together to carry out the dl behavior. a society is an instance of the cradle model defined according to a specific collaboration framework in the dl domain. a society is the highest-level component of a dl and exists to serve the information needs of its actors and to describe its context of usage. hence a dl collects, preserves, and shares information artefacts for society members. the basic entities in cradle are derived from the categorization along the actors, activities, components, figure 2. the cradle metamodel with the e/r formalism 176 information technology and libraries | december 2010 a text document, including scientific articles and books, becomes a sequence of strings. the struct entity a struct is a structural element specifying a part of a whole. in dls, structures represent hypertexts, taxonomies, relationships between elements, or containment. for example, books can be structured logically into chapters, sections, subsections, and paragraphs, or physically into cover, pages, line groups (paragraphs), and lines. structures are represented as graphs, and the struct entity (a vertex) contains four attributes: 1. document is a pointer to the document entity the structure refers to. 2. id is a unique identifier for a structure element. 3. type takes three possible values: i. metadata denotes a content descriptor, for instance title, author, etc. ii. layout denotes the associated layout, e.g., left frame, columns, etc. iii. item indicates a generic structure element used for extending the model. 4. values is a list of values describing the element content, e.g., title, author, etc. actors interact with services in an event-driven way. services are connected via messages (send and reply) and can be sequential, concurrent, or task-related (when a service acts as a subtask of a macroservice). services perform operations (e.g., get, add, and del) on collections, producing collections of documents as results. struct elements are connected to each other as nodes of a graph representing metadata structures associated with documents. the metamodel has been translated to a dsvl, associating symbols and icons with entities and relations (see “cradle language and tools” below). with respect to the six core concepts of the delos manifesto (content, user, functionality, quality, policy, and architecture), content can be modeled in cradle as collections and structs, user as actor, and functionality as service. the quality concept is not directly modeled in cradle, but for quality of service we support standard service architecture. policies can be partially modeled by services managing interaction between actors and collections, making it possible to apply standard access policies. from the architectural point of view, we follow the reference architecture of figure 1. ■■ cradle language and tools in this section we describe the selection of languages and tools of the cradle platform. to improve interoperability service entities services describe scenarios, activities, operations, and tasks that ultimately specify the functionalities of a dl, such as collecting, creating, disseminating, evaluating, organizing, personalizing, preserving, requesting, and selecting documents and providing services to humans concerned with fact-finding, learning, gathering, and exploring the content of a dl. all these activities can be described and implemented using scenarios and appear in the dl setting as a result of actors using services (thus societies). furthermore, these activities realize and shape relationships within and between societies, services, and structures. in the cradle metamodel, the service entity models what the system is required to do, in terms of actions and processes, to achieve a task. a detailed task analysis helps understand the current system and the information flow within it in order to design and allocate tasks appropriately. the service entity has four attributes: 1. name is a string representing a textual description of the service. 2. sync states whether communication is synchronous or asynchronous, modeled by values wait and nowait, respectively. 3. events is a list of messages that can trigger actions among services (tasks); for example, valid or notvalid in case of a parsing service. 4. responses contain a list of response messages that can reply to raised events; they are used as a communication mechanism by actors and services. the collection entity collections are sets of documents of arbitrary type (e.g., bits, characters, images, etc.) used to model static or dynamic content. in the static interpretation, a collection defines information content interpreted as a set of basic elements, often of the same type, such as plain text. examples of dynamic content include video delivered to a viewer, animated presentations, and so on. the attributes of collection are name and documents. name is a string, while documents is a list of pairs (documentname, documentlabel), the latter being a pointer to the document entity. the document entity documents are the basic elements in a dl and are modeled with attributes label and structure. label defines a textual string used by a collection entity to refer to the document. we can consider it as a document identifier, specifying a class or a type of document. structure defines the semantics and area of application of the document. for example, any textual representation can be seen as a string of characters, so that generating collaborative systems for digital libraries | malizia, bottoni, and levialdi 177 graphs. model manipulation can then be expressed via graph grammars also specified in atom3. the general process of automatic creation of cooperative dl environments for an application is shown in figure 3. initially, a designer formalizes a conceptual description of the dl using the cradle metamodel concepts. this phase is usually preceded by an analysis of requirements and interaction scenarios, as seen previously. model specifications are then provided to a dl code generator (written in python within atom3) to produce dls tailored to specific platforms and requirements. these are built on a collection of templates of services and configurable components providing infrastructure for the new dl. the sketched infrastructure includes classes for objects (tasks), relationships making up the dl, and processing tools to upload the actual library collection from raw documents, as well as services for searching and browsing and for document collections maintenance. the cradle generator automatically generates different kinds of output for the cradle model of the cooperative dl environment, such as service and collection managers. collection managers define the logical schemata of the dl, which in cradle correspond to a set of mime types, xul and xdoclet specifications, representing digital objects, their component parts, and linking information. collection managers also store instances of their and collaboration, cradle makes extensive use of existing standard specification languages. most cradle outputs are defined with xml-based formats, able to enclose other specific languages. the basic languages and corresponding tools used in cradle are the following: ■■ mime type. multipurpose internet mail extensions (mime) constitute the basis for encoding documents in cradle, supporting several file formats and types of character encoding. mime was chosen because of wide availability of mime types, and standardisation of the approach. this makes it a natural choice for dls where different types of documents need to be managed (pdf, html, doc, etc.). moreover, mime standards for character encoding descriptions help keeping the cradle framework open and compliant with standards. ■■ xul. the xml user interface language (xul) is an xml-based markup language used to represent appearance and visual interfaces. xul is not a public standard yet, but it uses many existing standards and technologies, including dtd and rdf,44 which makes it easily readable for people with a background in web programming and design. the main benefit of xul is that it provides a simple definition of common user interface elements (widgets). this drastically reduces the software development effort required for visual interfaces. ■■ xdoclet. xdoclet is used for generating services from tagged-code fragments. it is an open-source code generation library which enables attribute-oriented programming for java via insertion of special tags.45 it includes a library of predefined tags, which simplify coding for various technologies, e.g., web services. the motivation for using xdoclet in the cradle framework is related to its approach for template code generation. designers can describe templates for each service (browse, query, and index) and the xdoclet generated code can be automatically transformed into the java code for managing the specified service. ■■ atom3. atom3 is a metamodeling system to model graphical formalisms. starting from a metaspecification (in e/r), atom3 generates a tool to process models described in the chosen formalism. models are internally represented using abstract syntax figure 3. cooperative dl generation process with cradle framework 178 information technology and libraries | december 2010 and (3) the metadata operations box. the right column manages visualization and multimedia information obtained from documents. the basic features provided with the ui templates are document loading, visualization, metadata organization, and management. the layout template, in the collection box, manages the visualization of the documents contained in a collection, while the visualization template works according to the data (mime) type specified by the document. actually, by selecting a document included in the collection, the corresponding data file is automatically uploaded and visualized in the ui. the metadata visualization in the code template reflects the metadata structure (a tree) represented by a struct, specifying the relationship between parent and child nodes. thus the xul template includes an area (the metadata box) for managing tree structures as described in the visual model of the dl. although the tree-like visualization has potential drawbacks if there are many metadata items, there should be no real concern with medium loads. the ui template also includes a box to perform operations on metadata, such as insert, delete, and edit. users can select a value in the metadata box and manipulate the presented values. figure 4 shows an example of a ui generated from a basic template. service templates to achieve automated code generation, we use xdoclet to specify parameters and service code generation according to such parameters. cradle can automatically annotate java files with name–value pairs, and xdoclet provides a syntax for parameter specification. code generation is classes and function as search engines for the system. services classes also are generated and are represented as attribute-oriented classes involving parts and features of entities. ■■ cradle platform the cradle platform is based on a model-driven approach for the design and automatic generation of code for dls. in particular, the dsvl for cradle has four diagram types (collection, structure, service, and actor) to describe the different aspects of a dl. in this section we describe the user interface (ui) and service templates used for generating the dl tools. in particular, the ui layout is mainly generated from the structured information provided by the document, struct, and collection entities. the ui events are managed by invoking the appropriate services according to the imported xul templates. at the service and communication levels, the xdoclet code is generated by the service and actor entities, exploiting their relationships. we also show how code generation works and the advanced platform features, such as automatic service discovery. at the end of the section a running example is shown, representing all the phases involved in using the cradle framework for generating the dl tools for a typical library scenario. user interface templates the generation of the ui is driven by the visual model designed by the cradle user. specifically, the model entities involved in this process are document, struct and collection (see figure 2) for the basic components and layout of the interfaces, while linked services are described in the appropriate templates. the code generation process takes place through transformations implemented as actions in the atom3 metamodel specification, where graph-grammar rules may have a condition that must be satisfied for the rule to be applied (preconditions), as well as actions to be performed when the rule is executed (postconditions). a transformation is described during the visual modeling phase in terms of conditions and corresponding actions (inserting xul language statements for the interface in the appropriate code template placeholders). the generated user interface is built on a set of xul template files that are automatically specialized on the basis of the attributes and relationships designed in the visual modeling phase. the layout template for the user interface is divided into two columns (see figure 4). the left column is made of three boxes: (1) the collection box (2) the metadata box, figure 4. an example of an automatically generated user interface. (a) document area; (b) collection box; (c) metadata box; (d) metadata operations box. generating collaborative systems for digital libraries | malizia, bottoni, and levialdi 179 "msg arguments.argname"> { "<xdtfield : fieldname/>" , "<xdtfield : fieldtagvalue tagname= "msg arguments.argname" paramname="name"/>" "<xdtfield : fieldtagvalue tagname= "msg arguments.argname" paramname=" desc "/>" } , </xdtfield : ifhasfieldtag> </xdtfield : forallfields> }; the first two lines declare a class with a name class nameimpl that extends the class name. the xdoclet template tag xdtclass:classname denotes the name of the class in the annotated java file. all standard xdoclet template tags have a namespace starting with “xdt.” the rest of the template uses xdtfield : forallfield to iterate through the fields. for each field with a tag named msg arguments.argname (checked using xdtfield : ifhasfieldtag), it creates a subarray of strings using the values obtained from the field tag parameters. xdtfield : fieldname gives the name of the field, while xdtfield : fieldtagvalue retrieves the value of a given field tag parameter. characters that are not part of some xdoclet template tags are directly copied into the generated code. the following code segment was generated by xdoclet using the annotated fields and the above template segment: public class msgargumentsimpl extends msgarguments { public static string[ ][ ] argumentnames = new string[ ][ ]{ { "eventmsg" , " event " , " eventstring " } , { " responsemsg " , " response " , " responsestring " } , }; } similarly, we generate the getter and setter methods for each field: <xdtfield : forallfields > <xdtfield : ifhasfieldtag tagname="msg arguments.argname"> public <xdtfield : fieldtype/> get <xdtfield : fieldname />() { return <xdtfield : fieldname />; } public void set <xdtfield : fieldname /> ( string value ) { based on code templates. hence service templates are xdoclet templates for transforming xdoclet code fragments obtained from the modeled service entities. the basic xdoclet template manages messages between services, according to the event and response attributes described in “cradle language and tools” above. in fact, cradle generates a java application (a service) that needs to receive messages (event) and reply to them (response) as parameters for the service application. in xdoclet, these can be attached to the corresponding field by means of annotation tags, as in the following code segments: public class msgarguments { . . . . . . /* * @msg arguments.argname name="event " desc="event_string " */ protected string eventmsg = null; /* * @msg arguments.argname name="response" * desc="response_string " */ protected string responsemsg = null; } each msg arguments.argname related to a field is called a field tag. each field tag can have multiple parameters, listed after the field tag. in the tag name msg arguments .argname, the prefix serves as the namespace of all tags for this particular xdoclet application, thus avoiding naming conflicts with other standard or customized xdoclet tags. not only fields can be annotated, but also other entities such as class and functions can have tags too. xdoclet enables powerful code generation requiring little or no customization (depending on how much is provided by the template). the type of code to be generated using the parameters is defined by the corresponding xdoclet template. we have created template files composed of java codes and special xdoclet instructions in the form of xml tags. these xdoclet instructions allow conditionals (if) and loops (for), thus providing us with expressive power close to a programming language. in the following example, we first create an array containing labels and other information for each argument: public class <xdtclass : classof> <xdtclass : classname/>impl</xdtclass : classof> extends <xdtclass : classof><xdtclass : classname/> </xdtclass : classof> { public static string[ ][ ] argumentnames = new string[ ][ ] { <xdtfield : forallfields> <xdtfield : ifhasfieldtag tagname= 180 information technology and libraries | december 2010 because different design choices in the template can lead to vastly different code. we have included an incremental mechanism by which users can modify the visual model of a dl and regenerate (xul interface) code only for the modifications. by employing this solution, librarians and dl designers can work as they would on paper by designing the visual scheme and collaboratively updating and changing it. they can generate the code, verify the implementation, and, if something has to be changed, go back to the visual model, apply modification, and generate code in a new iteration of the process. once the visual model has been modified, the system incrementally updates the code by examining only those model parts affected by the edit and modifying the corresponding parts of the generated code. the same approach could be used for services but with a different technique. in fact, predefined templates exist for basic services, e.g., indexing, uploading, and querying. to allow service providers to add new code to the rest of the service component list, we have implemented a registry listing the available service templates. when the user runs the code generation process, a routine verifies if the service templates included in the model are available in the registry and loads it into memory for the code generation process. we are planning to support a standard mechanism based on the universal description, discovery, and integration registry.47 moreover, we have developed an advanced interface template that embeds validation code into the xul templates for the interfaces to look up the list of services made available by the interface at run-time. if there are services embedded in the interface but not available, the interface is modified to prevent access to them. for instance, suppose that an interface is specified with buttons to access to the document upload and edit services. if, at run-time, the check does not find the edit service available, the interface will present only the button for the upload service. ■■ generating a digital library environment as a first step in designing the digital library environment in the cradle framework, designers model the society involved in the specific scenario. we define a running example, called library, to show the process, starting from the basic entities of the model. we consider modeling a simple dl environment. the involved actors are students and librarians. the dl collection consists of digital paper documents with publication, author, and title metadata information (struct entities). in figure 5, the cradle environment (a society) is shown together with the defined entities. circles represent actors in the model, rectangles render services, multiple rectangles represent setvalue ( "<xdtfield : fieldname/>" , value ) ; }< /xdtfield : ifhasfieldtag> </xdtfield : forallfields > this translates into the following generated code: public java.lang.string get eventmsg ( ) { return eventmsg ; } public void set eventmsg ( string value ) { setvalue ( "eventmsg" , value ) ; } public java.lang.string getresponsemsg ( ) { return getresponsemsg ; } public void setresponsemsg ( string value ) { setvalue ( " responsemsg " , value ) ; } the same template is used for managing the name and sync attributes of service entities. code generation, service discovery, and advanced features a service or interface template only describes the solution to a particular design problem—it is not code. consequently, users will find it difficult to make the leap from the template description to a particular implementation even though the template might include sample code. others, like software engineers, might have no trouble translating the template into code, but they still may find it a chore, especially when they have to do it repeatedly. the cradle visual design environment (based on atom3) helps alleviate these problems. from just a few pieces of information (the visual model), typically application-specific names for actors and services in a dl society along with choices for the design tradeoffs, the tool can create class declarations and definitions implementing the template. the ultimate goal of the modeling effort remains, however, the production of reliable and efficiently executable code. hence a code generation transformation produces interface (xul) and service (java code from xdoclet templates) code from the dl model. we have manually coded xul templates specifying the static setup of the gui, the various widgets and their layout. this must be complemented with code generated from a dl model of the systems dynamics coded into services. while other approaches are possible,46 we employed the solution implemented within the atom3 environment according to its graph grammar modeling approach to code generation. cradle supports a flexible iterative process for visual design and code generation. in fact, a design change might require substantial reimplementation generating collaborative systems for digital libraries | malizia, bottoni, and levialdi 181 selecting one, the ui activates the metadata operations box—figure 6(d). the selected metadata node will then be presented in the lower (metadata operations) box, labeled “set metadata values,” replacing the default “none” value as shown in figure 6. after the metadata item is presented, the user can edit its value and save it by clicking on the “set value” button. the associated action saves the metadata information and causes its display in the intermediate box (tree-like structure), changing the visualization according to the new values. the code generation process for the do_search and front desk services is based on xdoclet templates. in particular, a message listener template is used to generate the java code for the front desk service. in fact, the front desk service is asynchronous and manages communications between actors. the actors classes are generated also by using the services templates since they have attributes, events, and messages, just like the services. the do_search service code is based on the producer and consumer templates, since it is synchronous by definition in the modeled scenario. a get method retrieving a collection of documents is implemented from the getter template. the routine invoked by the transformation action for struct entities performs a breadth-first exploration of the metadata tree in the visual model and attaches the corresponding xul code for displaying the struct node in the correct position within the graph structure of the ui. collections, while a single rectangle connected to a collection represents a document entity; the circles linked to the document entity are the struct (metadata) entities. metadata entities are linked to the node relationships (organized as a tree) and linked to the document entity by a metadata linktype relationship. the search service is synchronous (sync attribute set to “wait”). it queries the document collection (get operation) looking for the requested document (using metadata information provided by the borrow request), and waits for the result of get (a collection of documents). based on this result, the service returns a boolean message “is_available,” which is then propagated as a response to the librarian and eventually to the student, as shown in figure 5. when the library designer has built the model, the transformation process can be run, executing the code generation actions associated with the entities and services represented in the model. the code generation process is based on template code snippets generated from the atom3 environment graph transformation engine, following the generative rules of the metamodel. we also use pre– and postconditions on application of transformation rules to have code generation depend on verification of some property. the generated ui is presented in figure 6. on the right side, the document area is presented according to the xul template. documents are managed according to their mime type: the pdf file of the example is loaded with the appropriate adobe acrobat reader plug-in. on the left column of the ui are three boxes, according to the xul template. the collection box—figure 6(b)— presents the list of documents contained in the collection specified by the documents attribute of the library collection entity, and allows users to interact with documents. after selecting a document by clicking on the list, it is presented in the document area—figure 6(a)—where it can be managed (edit, print, save, etc.). in the metadata box—figure 6(c)—the tree structure of the metadata is depicted according to the categorization modeled by the designer. the xul template contains all the basic layout and action features for managing a tree structure. the generated box contains the parent and child nodes according to the attributes specified in the corresponding struct elements. the user can click on the root for compacting or exploding the tree nodes; by figure 5. the library model, alias the model of the library society 182 information technology and libraries | december 2010 workflow system. the release collection maintains the image files in a permanent storage, while data is written to the target database or content management software, together with xml metadata snippets (e.g., to be stored in xml native dbms). a typical configuration would have the recognition service running on a server cluster, with many dataentry services running on different clients (web browsers directly support xul interfaces). whereas current document capture environments are proprietary and closed, the definition of an xml-based interchange format allows the suitable assembly of different component-based technologies in order to define a complex framework. the realization of the jdan dl system within the cradle framework can be considered as a preliminary step in the direction of a standard multimedia document managing platform with region segmentation and classification, thus aiming at automatic recognition of image database and batch acquisition of multiple multimedia documents types and formats. personal and collaborative spaces a personal space is a virtual area (within the dl society) that is modeled as being owned and maintained by a user including resources (document collections, services, etc.), or references to resources, which are relevant to a task, or set of tasks, the user needs to carry out in the dl. personal spaces may thus contain digital documents in multiple media, personal schedules, visualization tools, and user agents (shaped as services) entitled with various tasks. resources within personal spaces can be allocated ■■ designing and generating advanced collaborative dl systems in this section we show the use of cradle as an analytical tool helpful in comprehending specific dl phenomena, to present the complex interplays that occur between cradle components and dl concepts in a real dl application, and to illustrate the possibility of using cradle as a tool to design and generate advanced tools for dl development. modeling document images collections with cradle, the designer can provide the visual model of the dl society involved in document management and the remaining phases are automatically carried out by cradle modules and templates. we have provided the user with basic code templates for the recognition and indexing services, the data-entry plug-in, and archive release. the designer can thus simply translate the particular dl society into the corresponding visual model within the cradle visual modeling editor. as a proof of concept, figure 7 models the jdan architecture, introduced in “requirements for modeling digital libraries,” exploiting the cradle visual language. the recognition service performs the automatic document recognition and stores the corresponding document images, together with the extracted metadata in the archive collection. it interacts with the scanner actor, representing a machine or a human operator that scans paper documents. designers can choose their own segmentation method or algorithm; what is required to be compliant with the framework is to produce an xdoclet template. it stores the document images into the archive collection, with its different regions layout information according to the xml metadata schema provided by the designer. if there is at least one region marked as “not interpreted,” the dataentry service is invoked on the “not interpreted” regions. the data-entry service allows operators to evaluate the automatic classification performed by the system and edit the segmentation for indexing. operators can also edit the recognized regions with the classification engine (included in the recognition service) and adjust their values and sizes. the output of this phase is an xml description that will be imported in the indexing service for indexing (and eventually querying). the archive collection stores all of the basic information kept in jdan, such as text labels, while the indexing service, based on a multitier architecture, exploiting jboss 3.0, has access to them. this service is responsible for turning the data fragments in the archive collection into useful forms to be presented to the final users, e.g., a report or a query result. the final stage in the recognition process could be to release each document to a content management or figure 6. the ui generated by cradle transforming the library model in xul and xdoclet code generating collaborative systems for digital libraries | malizia, bottoni, and levialdi 183 and metadata, but also can share information with the various committees collaborating for certain tasks. ■■ evaluation in this section we evaluate the presented approach from three different perspectives: usability of the cradle notation, its expressiveness, and usability of the generated dls. usability of cradle notation we have tested it by using the well known cognitive dimensions framework for notations and visual language design.48 the dimensions are usually employed to evaluate the usability of a visual language or notation, or as heuristics to drive the design of innovative visual languages. the significant results are as follows. abstraction gradient an abstraction is a grouping of elements to be treated as one entity. in this sense, cradle is abstraction-tolerant. it provides entities for high-level abstractions of communication processes and services. these abstractions are intuitive as they are visualized as the process they represent (services with events and responses) and easy to learn as their configuration implies few simple attributes. although cradle does not allow users to build new abstractions, the e/r formalism is powerful enough to provide basic abstraction levels. closeness of mapping cradle elements have been assigned icons to resemble their real-world counterparts (e.g., a collection is represented as a set of paper sheets). the elements that do not have a correspondence with a physical object in the real world have icons borrowed from well-known notations (e.g., structs represented as graph nodes). consistency a notation is consistent if a user knowing some of its structure can infer most of the rest. in cradle, when two elements represent the same entity but can be used either as input or as output, then their shape is equal but incorporates an incoming or an outgoing message in order to differentiate them. see, for example, the icons for services or those for graph nodes representing either a according to the user’s role. for example, a conference chair would have access to conference-specific materials, visualization tools and interfaces to upload papers for review by a committee. similarly, we denote a group space as a virtual area in which library users (the entire dl society) can meet to conduct collaborative activities synchronously or asynchronously. explicit group spaces are created dynamically by a designer or facilitator who becomes (or appoints) the owner of the space and defines who the participants will be. in addition to direct user-touser communication, users should be able to access library materials and make annotations on them for every other group to see. ideally, users should be able to act (and carry dl materials with them) between personal and group spaces or among group spaces to which they belong. it may also be the case, however, that a given resource is referenced in several personal or group spaces. basic functionality required for personal spaces includes capabilities for viewing, launching, and monitoring library services, agents, and applications. like group spaces, personal spaces should provide users with the means to easily become aware of other users and resources that are present in a given group space at any time, as well as mechanisms to communicate with other users and make annotations on library resources. we employed this personal and group space paradigm in modeling a collaborative environment in the academic conferences domain, where a conference chair can have a personal view of the document collections (resources) figure 7. the cradle model for the jdan framwork 184 information technology and libraries | december 2010 of “sapienza” university of rome (undergraduate students), shown in figure 5, and (2) an application employed with a project of records management in a collaboration between the computer science and the computer engineering department of “sapienza” university, as shown in figure 7. usability of the generated tools environments for single-view languages generated with atom3 have been extensively used, mostly in an academic setting, in different areas like software and web engineering, modeling, and simulation; urban planning; etc. however, depending on the kind of the domain, generating the results may take some time. for instance, the state reachability analysis in the dl example takes a few minutes; we are currently employing a version of atom3 that includes petri-nets formalism where we can test the services states reachability.49 in general, from application experience, we note the general agreement that automated syntactical consistency support greatly simplifies the design of complex systems. finally, some users pointed out some technical limitations of the current implementation, such as the fact that it is not possible to open several views at a time. altogether, we believe this work contributes to make more efficient and less tedious the definition and maintenance of environments for dls. our model-based approach must be contrasted with the programmingcentric approach of most case tools, where the language and the code generation tools are hard-coded so that whenever a modification has to be done (whether on the language or on the semantic domain) developers have to dive into the code. ■■ conclusions and future work dls are complex information systems that integrate findings from disciplines such as hypertext, information retrieval, multimedia, databases, and hci. dl design is often a multidisciplinary effort, including library staff and computer scientists. wasted effort and poor interoperability can therefore ensue. examining the related bibliography, we noted that there is a lack of tools or automatic systems for designing and developing cooperative dl systems. moreover, there is a need for modeling interactions between dls and users, such as scenario or activity-based approaches. the cradle framework fulfills this gap by providing a model-driven approach for generating visual interaction tools for dls, supporting design and automatic generation of code for dls. in particular, we use a metamodel made of different diagram types (collection, structures, service, and struct or an actor, with different colors. diffuseness/terseness a notation is diffuse when many elements are needed to express one concept. cradle is terse and not diffuse because each entity expresses a meaning on its own. error-proneness data flow visualization reduces the chance of errors at a first level of the specification. on the other hand, some mistakes can be introduced when specifying visual entities, since it is possible to express relations between source and target models which cannot generate semantically correct code. however, these mistakes should be considered “programming errors more than slips,” and may be detected through progressive evaluation. hidden dependencies a hidden dependency is a relation between two elements that is not visible. in cradle, relevant dependencies are represented as data flows via directed links. progressive evaluation each dl model can be tested as soon as it is defined, without having to wait until the whole model is finished. the visual interface for the dl can be generated with just one click, and services can be subsequently added to test their functionalities. viscosity cradle has a low viscosity because making small changes in a part of a specification does not imply lots of readjustments in the rest of it. one can change properties, events or responses and these changes will have only local effect. the only local changes that could imply performing further changes by hand are deleting entities or changing names; however, this would imply minimal changes (just removing or updating references to them) and would only affect a small set of subsequent elements in the same data flow. visibility a dl specification consists of a single set of diagrams fitting in one window. empirically, we have observed that this model usually involves no more than fifteen entities. different, independent cradle models can be simultaneously shown in different windows. expressiveness of cradle the paper has illustrated the expressiveness of cradle by defining different entities end relationships for different dl requisites. to this end, two different applications have been

digital user-learner profiles. thematic digital universities are similar to digital libraries, and focus on creating and indexing open educational resources, as well as improving learning in the information age. the digital user profile relates to the digital representation of a person’s identity and characteristics. in this paper we present the design of an ontology for the digital user-learner profile (ontoulp) and its application program. ontoulp is used to structure a user-learner’s digital profile. the application provides each user-learner with tailor-made analyses based on informational behaviors, needs, and preferences. we rely on an exploratory research approach and on methods of ontologies, user modeling, and semantic matching to design the ontoulp and its application program. any user-learner could use the ontoulp and its application program. introduction more online learning environments are supporting the creation and dissemination of quality open educational resources (oer) to facilitate change in the education sector, improve education, ensure longlife learning, reduce cost, and other motives.1 in 2002, the united nations educational, scientific and cultural organization (unesco) recommended the definition of oer as follows: “the open provision of educational resources, enabled by information and communication technologies, for consultation, use and adaptation by a community of users for non-commercial purposes.”2 the william and flora hewlett foundation defined oer as “freely licensed, remixable learning resources—[they] offer a promising solution to the perennial challenge of delivering high levels of student learning at lower cost.”3 in 2012, unesco noted that oer offer education stakeholders an opportunity to access textbooks and other learning contents to enhance their knowledge and professional experiences.4 education stakeholders may choose oer based on their informational needs, behaviors, and preferences.5 we hope to contribute to the field of research in information technology and digital libraries by analyzing the connections between thematic digital universities and digital user-learner profiles. we are conducting a case study using the digital university engineering and technology.6 in the following we will explain these topics and the interest in the digital university engineering and technology. in 2003, the french ministry of higher education, research, and innovation initiated the creation of thematic digital universities to facilitate the integration and use of information and mailto:marilou_kordahi@yahoo.fr information technology and libraries june 2022 ontology for the user-learner profile | kordahi 2 communication technologies for education in university teaching practices.7 in total, there are six thematic digital universities which are organized by broad disciplines: health sciences and sports, engineering sciences, environment and sustainable development, humanities, economics and management, as well as technical studies. thematic digital universities are similar to digital libraries, and focus on creating and indexing oer, as well as improving learning in the information age.8 although thematic digital libraries are mostly comprised of oer, they also develop complete training programs with some of these resources (e.g., massive open online courses, or moocs). they are partners with canal-u, the video library for higher education, as well as the french national platform for massive open online courses (fun-mooc). thematic digital universities are mostly created for learners and teachers, as they offer complementary educational resources to bachelor, masters, and doctoral programs.9 to date, learners and teachers have free access to most thematic digital universities and corresponding educational resources. registration is not required; however, without registration neither the learner nor the teacher can analyze her/his search for oer based on informational behaviors, needs, and preferences.10 we will focus on the analysis of oer metadata records in the context of thematic digital universities. each oer in the repository holds a metadata record to precisely describe its specifications to the learner or teacher (e.g., the learning level, language, and topics). specifications are written according to the institute of electrical and electronics engineers (ieee) standards for learning object metadata (lom),11 lomfr, and suplomfr. lom provides an accurate descriptive schema of a learning object suitable for educational resources12 (e.g., the classification and identification of an educational resource). lomfr and suplomfr are currently applications of lom in the french educational community.13 the digital university engineering and technology attracted our attention because of the following characteristics: clear presentation of its objectives, regular information updates, priority for free access to oer and open data, 3,000 published educational resources, extensive documentation of oer indexing, interoperability of oer and metadata records, and an advanced search engine for oer. each metadata record describes precise information on the oer, including the main title, keywords, descriptive text, educational types (or resources), learning level, copyrights, knowledge domains, topics, authors, and publishers. it is processed and structured with xml language which is human-readable and machine-readable. digital user profiles relate to the digital representation of a person’s identity and characteristics.14 digital identity is the sum of digital traces (or “footprints”) relating to an individual or a community found on the web or in digital systems. digital traces correspond to the user’s profile, browsing history, and contribution actions.15 our focus is the learner who wishes to use the thematic digital universities for tailor-made analysis of retrieved information based on her/his needs and preferences. we offer the learner an option to register on these platforms to track behavior over time while searching for oer. analyses are based on criteria the learner has previously chosen to personalize this search. subsequently, we suggest using the term “digital user-learner profile.” we will do our best to respect the general data protection regulations when collecting information on the digital userlearner profile.16 the general data protection regulations are privacy laws drafted and passed by information technology and libraries june 2022 ontology for the user-learner profile | kordahi 3 the european union that prohibit the processing, storage, or sharing of certain types of information about individuals without their knowledge and consent. the research questions are as follows: 1. in the context of thematic digital universities, how can a user-learner personalize the search for open educational resources according to her/his digital profile? 2. in this same context, what kinds of information can a user-learner analyze in a search for open educational resources according to her/his digital profile? the objectives of this article are to present the preliminary results of work in progress on the design of the ontology for the digital user-learner profile (ontoulp) and its application program, the personalized modeling system for the user-learner profile (psul). we rely on the methods of ontology,17 user modeling,18 and semantic matching.19 the method of ontology is used to describe in a formal manner a set of concepts and objects which represent the meaning of an information system in a specific area and the relationships between these concepts and objects.20 the method of user modeling describes the process of designing and changing a user’s conceptual understanding. it is applied to customize and adjust systems to meet the user’s needs and preferences. the method of semantic matching is used to identify and relate a meaning concept (or class) to its homologous concept in tree-like schemas and to consider the concept’s position in these schemas (e.g., mapping a class in an ontology to homologous concepts in metadata records). this relationship can be a one-to-one concept or one-to-many concepts. the ontoulp is a first approach, and it will be used to structure a user-learner’s digital profile in the context of thematic digital universities. we design this ontology for three main reasons: to structure collected and generated information21 (e.g., structuring a user-learner’s learning preferences will enable the identification of learning behaviors and activities), to analyze collected and generated information22 (e.g., analyzing generated information by a user-learner may predict a search for oer), as well as to facilitate relationships between a user-learner and thematic digital universities23 (e.g., analyzing user-learner informational behaviors may improve oer creation and dissemination). the psul will be designed as an application program for the ontoulp. it will be used to provide each user-learner with tailor-made analyses based on informational behaviors, needs, and preferences. psul will include a secure database and web pages, namely those for registering and editing the user-learner profile and its dashboard.24 ontoulp and its application program will offer each registered user-learner an opportunity to analyze the search for oer according to informational behaviors and needs. ontoulp and psul could be implemented in the structure of information systems for educational and research institutions, documentation and information centers, and many others. we will finetune our analysis by relying on a case example—the thematic digital universities. this article comprises six sections. first, we will explain the exploratory research carried out in the context of thematic digital universities. second, we will present the main published works related to the subject of the article. third, we will explain the approach followed to design and write the ontoulp. fourth, we will discuss the creation of the psul application program. fifth, we will demonstrate the integration of the designed ontology and its application program into a information technology and libraries june 2022 ontology for the user-learner profile | kordahi 4 mirror site to perform a technical test. finally, we will discuss the completed work before concluding the article. exploratory research approach this exploratory research is based on an analysis of the literature, a semistructured questionnaire, and an in-depth documentary research. we check the consistency of collected information and identify the need to personalize the search for oer as well as make tailor-made analysis of information. methods used during the first 18 months of the covid-19 pandemic (november 2020–may 2021), we conducted qualitative research to deepen our comprehension of the practices of thematic digital universities. we collected and interpreted primary and secondary information. primary information: we contacted the digital university association and their six thematic digital universities.25 because of their extensive expertise and robust knowledge in leading or managing thematic digital universities, directors and general secretaries were chosen to selfadminister an electronic semistructured questionnaire. we contacted seven individuals and received six responses. in this questionnaire, we asked about the following topics: the recent knowledge of thematic digital universities, conditions of access to oer, metadata records indexing as well as user-learner’s expectations. an example of the questionnaire is included in the appendix. secondary information: we analyzed a report by the french general inspectorate of the national education and research administration. we have also studied recently-published scientific articles by anne boyer (2011), deborah arnold (2018),26 and sihem zghidi and mokhtar ben henda (2020). the results and findings will be explained in the following paragraphs. results of information collection we have compared responses to the questionnaire and contents of published documents and articles. for the digital university in health sciences and sports, “resources are mostly accessible to learners from member universities, through an identification system based on the university email address.”27 only a few resources are open to the public. otherwise, according to comments gathered from the other four digital universities and digital university association, “thematic digital universities are part of global movements providing access to oer by promoting open access to knowledge.”28 they are an opportunity for learners to discover new disciplines and explore new areas.29 in fact, “the process for indexing metadata records meets standards for education, such as lom, lomfr and suplomfr.”30 at present, there is no feedback on the use of thematic digital universities platforms. in other words, “thematic digital universities have no information about learners who view oer, because there is no login and password. this is done on purpose to make them as open as possible.”31 these platforms are considered as a means of selftraining with quality assurance, as the documents have been produced and validated by higher education teachers. “thematic digital universities provide a certain flexibility allowing learners to work when and where they want.”32 information technology and libraries june 2022 ontology for the user-learner profile | kordahi 5 findings five thematic digital universities and the digital university association responded to the semistructured questionnaire. two thematic digital universities can track user-learners’ behaviors. these digital universities are related to the disciplines of health and sport in addition to technical studies. to date, four thematic digital universities cannot track user-learners’ interactions based on informational behaviors and preferences. ontoulp and its application program could be implemented in four thematic digital universities, which are related to the disciplines of engineering sciences, environment and sustainable development, humanities, economics, and management. literature review to our best knowledge, published research works addressing this research subject are limited in the context of thematic digital universities.33 we analyze the most recent ontologies and user modeling systems that are close to our research objectives. the main works we use are those of bloom et al. (1984),34 smythe et al. (2001),35 green and panzer (2009),36 and kordahi (2020),37 in addition to kelly and belkin (2002). the work methods and field studies these researchers have developed are useful to design the structure of the ontoulp and the model of its application program. in the following paragraphs, we will explain these works and the relationships with this research article. selection of recently published works in 2020 and 2021, kordahi designed an ontology and a personalized dashboard for user learners.38 the objectives of these works were to track individual searches for oer and compare them with a user-learner’s field of work. to design her ontology, kordahi relied on standardized ontologies and validated taxonomies which are used in online learning environments, namely the ims learner information profile (ims lip)39 and bloom’s taxonomy. the personalized dashboard was linked to the user-learner ontology. the designed dashboard was tested technically with its ontology in a digital library environment to examine its performance. kordahi used the methods of ontologies and semantic matching. learner model we are mostly interested in the learner model40 as it “is a model of the knowledge, difficulties and misconceptions of the individual [learner].” 41 as students learn the educational resources they find, the learner model is updated to display their current progress. the model can continue to tailor students’ interactions as they learn. there are several learner models, such as the ims lip.42 we examine the ims lip, which is based on a standardized data model describing a learner’s characteristics. it is mainly used to manage a student’s learning history to discover her/his learning opportunities. ims lip is made from 11 categories that gather learning information: “the identification, goals, qualifications and licenses, activity, interest, competency, accessibility, transcript, affiliation, security, and relationships.”43 this model has been successfully used by many renowned researchers (e.g., paquette 201044) to design a learner model and then adapt it to appropriate contexts. ims lip’s reliability, accuracy, and flexibility match well with the ontoulp motives. we will use it to begin designing the structure of the ontoulp and adapt it to the thematic digital universities context. we will also consider the ieee lom, lomfr, and suplomfr classification fields. this measure will be used to improve semantic matching between the ontoulp and oer metadata records. information technology and libraries june 2022 ontology for the user-learner profile | kordahi 6 taxonomy of educational objectives we examine the user-learner’s educational objectives to meet informational needs and expectations.45 in each oer metadata record, educational objectives are defined based on bloom’s taxonomy (e.g., “understand the context and rules of scientific publication” 46). bloom et al. have developed a taxonomy for educational objectives to classify statements teachers expected students to learn as a result of lessons and instructions. the researchers described a method for allowing students to achieve educational goals while carrying out exercises utilizing the resources of the environment. bloom et al. relied on in-depth qualitative studies to design and validate this taxonomy. bloom’s taxonomy contains the following six major categories related to the cognitive domain: knowledge, comprehension, application, analysis, synthesis, and evaluation. this taxonomy was revised in 2001 by lorin anderson et al.47 bloom’s taxonomy is still in use internationally as in the works of kordahi. integrating bloom’s taxonomy into the ontoulp will enhance the structure of a user-learner’s educational objectives. these educational objectives will be organized in six categories allowing the user-learner to refine her/his informational goals. therefore, we will create a mutual link between the user-learner’s educational objectives and oer educational objectives. knowledge domains knowledge organization systems48 are seen as a valuable component for searching for oer.49 our research includes analyses of oer metadata records to establish relationships between their knowledge topics and the user-learner’s topics of interest. in the thematic digital universities’ metadata records, a precise classification is reported respecting both knowledge topics and dewey decimal classification (e.g., geographic information systems (526.028 5)). 50 the dewey decimal classification and relative index 22nd edition,51 published in 2003 by the online computer library center,52 is being used worldwide in digital libraries and by the thematic digital universities.53 in their works published in 2009, green and panzer have developed an ontology to structure knowledge domains.54 this ontology recognizes two classes, which are dewey classes and knowledge topics. we selected the dewey decimal classification for the ontoulp because the thematic digital universities are already using it. we will rely on green and panzer’s ontology to structure the knowledge domains in the ontoulp (e.g., the use of dewey classes and knowledge topics). we will establish relationships between the knowledge domains and user-learner model, allowing the user-learner to choose the most appropriate learning topics. user modeling system the “user modeling system for personalized interaction and tailored retrieval” is useful for analyzing each user-learner’s informational needs and preferences.55 kelly and belkin’s system helps the user to track informational needs over time. it contains three classes of models and a set of interactions. the “general behavioral model” tracks information seeking and user behavior to determine informational needs. the “personal behavioral model” characterizes each user’s information search according to specific preferences and behaviors. the “topical models” are associated with concepts related to each user’s informational behaviors. this model is developed by renowned researchers specialized in information retrieval and corresponds to the objectives of the research article. we will use the structure of kelly and belkin’s model (2002) to design the psul application program, in the context of thematic digital information technology and libraries june 2022 ontology for the user-learner profile | kordahi 7 universities. relationships between both the psul and ontoulp ontology will be established to carry out personalized analyses of oer search. ontoulp ontology ontoulp’s design is based on the works discussed in the previous section. it consists of two stages. we start by writing it. we then describe the ontology and emphasize the relationships between different entities. writing the ontology we write ontoulp with protégé editor and use the hermit inference engine to check the consistency of classes and their relationships with objects. the ontology’s first approach is saved in owl format, which is compliant with the semantic web technologies. ontoulp description the ontology is comprised of five subsystems. these are: user-learner, user-learner model, educational objectives, learning design, and knowledge domains. each subsystem is composed of classes that inherit the attributes of the subsystem on which they depend. for brevity, the figures show the hierarchical representation of these subsystems. the user-learner subsystem contains all recorded private information on the digital user-learner profile. the classes personal information, identification sessions, and traces provide information about the user-learner’s behavior and search history for oer, e.g., the search duration for oer (see fig. 1). the user-learner model subsystem is responsible for structuring collected information related to learning behaviors and needs, namely the classes identification, interest, learning level (or qualifications and licenses), personal preferences (or accessibility), activities, learning objectives (or goals), affiliation, and network of contacts (or relationships). in the context of thematic digital universities, the resulting subsystem is composed of eight classes instead of eleven. the userlearner model subsystem conveys the structured information to the user-learner subsystem. figure 1 shows the structure of both subsystems, the user-learner and user-learner model. information technology and libraries june 2022 ontology for the user-learner profile | kordahi 8 figure 1. hierarchical representation of both subsystems, the user-learner and user-learner model. the educational objectives subsystem includes cognitive objectives involved in the process of acquiring knowledge. we design their structure by adapting bloom’s taxonomy. the cognitive objectives class includes six interrelated subclasses: remember (or knowledge), understand (or comprehension), apply (or application), analyze (or analysis), synthetize (or synthesis), and evaluate (or evaluation). the cognitive objectives class is enhanced with the ieee lom, lomfr, and suplomfr classification fields enabling the user-learner to choose objectives which best describe their needs and preferences, e.g., the class apply has subclasses design, choose (see fig. 2). information technology and libraries june 2022 ontology for the user-learner profile | kordahi 9 figure 2. hierarchical representation of educational objectives and learning design subsystems. the learning design subsystem is an adaptation of the ims learning design model, in the context of thematic digital universities.56 the learning design subsystem has two main classes: the userlearner’s environment and learning activities. the environment class has six thematic digital universities as subclasses. in a general manner, information about the environment class comes from thematic digital universities platforms (e.g., the viewed metadata records). the learning activities class has resources as a subclass. the resources subclass is also enriched with the ieee lom, lomfr, and suplomfr classification fields to complete its structure and meet the userlearner’s needs and expectations. further, we have connected the learning activities with cognitive objectives classes to ensure continuity between them (e.g., the subclass experimentation is associated with subclass analyze). figure 2 illustrates the main structure of both subsystems, the learning objectives and learning design. the knowledge domains subsystem contains the main class dewey decimal classification and class contacts. this main class has two subclasses: dewey classes, with the corresponding divisions as subclasses, and knowledge topics, with the corresponding subtopics as subclasses (e.g., science topic corresponds to dewey class 500, manufacturing subtopic corresponds to division 670). information technology and libraries june 2022 ontology for the user-learner profile | kordahi 10 figure 3. hierarchical representation of the subsystem knowledge domains. the subclass knowledge topics is related to the subclass user-learner’s learning topics to improve informational behavior analyses. the class contacts is linked to the subclass user-learner’s network of contacts to analyze the strength or weakness of networks between the user-learner and oer publishers/authors (see fig. 1). the subsystem knowledge domains can deal with questions which belong to different levels in the ontoulp. for example, which learning topics is the user-learner looking for? which network of contacts is the user-learner interested in? what are the activities related to the user-learner learning topics? what keywords searched relate to the user-learner’s learning topics?57 in figure 3, we show some of the subsystem’s elements. personalized modeling system for the user-learner profile the psul is based on the works discussed in the previous sections. it is written with php, javascript, and xml, computing languages for the web. this new modeling system comprises three classes of models: the general behavioral, personal behavioral, and topical (see fig. 4). the general behavioral model has two roles. it registers a user-learner’s digital profile in order to determine informational needs and preferences for oer. it also collects informational behaviors of a user-learner while viewing oer metadata records for tailor-made analyses. the general information technology and libraries june 2022 ontology for the user-learner profile | kordahi 11 behavioral model includes the ontology ontoulp as well as user-learner registration and editing pages. the registration page contains relevant information about a user-learner, an option to accept or reject data collection, and a list of choices for behavioral analyses. once registered, the user-learner can modify her/his profile from the editing page. both pages are mapped to the ontoulp to populate criteria fields. the user-learner profile information is stored in a secure database (as described in the introduction). the personal behavioral model is used to analyze information according to the registered digital user-learner profile and informational behaviors. it contains a set of queries to collect and tailor information for each user-learner. the sources of information are the general behavioral model and oer metadata records. this model is designed based on analyses of the general behavioral model. when a user-learner begins searching for oer, the general behavioral model provides the personal behavioral model with all profile information as well as the history of oer search. this information is transmitted to make an adjustment to the personalized user-learner profile. the user-learner profile changes as the personal behavioral model receives more information from the general behavioral model. informational interactions connect the personal behavioral model to topical models. the topical models bring together all analyses of oer search for each user-learner.58 they are inferred from the personal behavioral model. informational interactions connect the topical models to the general behavioral model. for now, we have designed four topical models and present their outcome in the user-learner dashboard page. this page may be used as a practical dashboard providing feedback to each user-learner, who can use these analyses to adjust or make changes in the profile or the oer search. topical model 1 is used to synthesize each user-learner’s search history and to suggest a profile adjustment. the suggested adjustment is based on analyses of user-learner behavioral trends.59 topical model 2 allows each user-learner to examine the list of knowledge topics which have caught her/his attention. it contains two separate lists describing viewed oer metadata records and matching them to the chosen topics of interest. topical model 3 shows comparative analyses between the user-learner’s preference criteria and viewed metadata records. the user-learner can interact with this model by comparing the chosen topics of interest to the viewed knowledge topics. the user-learner can also compare the chosen learning activities to the viewed teaching pedagogies. the teaching pedagogies as well as knowledge topics are extracted from oer

between searched keywords and chosen topics of interest (see fig. 5a and fig. 5b). figure 4 shows the diagram of psul as explained in the paragraph. information technology and libraries june 2022

university for now, ontoulp and its application program are implemented in the digital university engineering and technology private platform which is hosted on a private server. we conducted a technical test to mainly assess ontoulp’s precision and performance. the digital university’s team has sent us a complete archive of their oer metadata records. these oer metadata records are saved on the private server with the digital university engineering and technology platform. once a user-learner is registered to this platform, she/he can carry out actions through the psul. for example, these actions are a search by keyword, personalization of profile, tailored-made analysis of oer search, and visualization of analyses in the dashboard. information technology and libraries june 2022

5a and 5b, we show brief results of a technical test. in this example, the user-learner’s identity is fictitious, or the user-learner’s persona is a construct.61 information technology and libraries june 2022 ontology for the user-learner profile | kordahi 15 in other words, the user-learner’s identity is not real, it is fabricated to conduct and complete the technical test. when registering, this user-learner has selected the technology topic (dewey class 600) in addition to the management and public relations subtopic (dewey division 650). this userlearner has also selected all topical models. during a viewing session, this user-learner chose to search for oer while using a few keywords. the keywords were chosen according to the userlearner’s profile and in order to continue the technical test. discussion and conclusion the ontology for the digital user-learner profile is a first approach based on the semantic web. it is designed for the personalization of interactions and retrieval of tailored information. we have combined standardized and validated resources, such as the ims lip, bloom’s taxonomy, and knowledge domains ontology, to allow the user-learner’s search analyses. we have discussed the design of a new application program prototype allowing a user-learner to analyze the search for oer according to her/his digital profile. psul provides automated real-time feedback based on the user-learner’s search history and information she/he has inserted about herself/himself. we have then demonstrated the integration of the ontoulp and psul into a mirror site to perform a technical test. the ontology’s main characteristics are flexibility and adaptability. while designing ontoulp, we have reused or restructured resources to allow its use in other thematic digital universities and online learning environments, including digital libraries. another advantage of ontoulp is the application of several information processing techniques. for example, a registered user-learner can self-assess her/his search for oer by keywords. she/he can also analyze the relevance of the search for oer through the psul. we have successfully overcome three essential limitations. the first limitation concerns the literature on the subject (see literature review section). while contributing to the field of research in information technology and digital libraries, this work has also drawn on disciplines as diverse as those of education as well as cognitive, social, and human sciences. the terminological definitions of disciplines, concepts, and even methods vary over decades or centuries, and among groups of researchers. we have made every effort to define the different terms correctly and to cite the corresponding researchers. the second difficulty relates to the design of ontoulp. published works dealing with this topic are rare. we used an exploratory research approach and the published works of renowned international researchers to fine-tune our study (see the exploratory research approach and literature review sections). we then determined the classes and objects as well as relationships between them. the third constraint concerns the design of the psul by following the thematic digital universities policies and respecting the general data protection regulations. according to the regulations, we have opted for an optional registration to thematic digital universities and to collecting information on the digital user-learner profile. thus, the user-learner will always have the possibility of registering to these platforms to make a tailor-made information analysis according to the digital profile. as we conclude our work, we have a plan to focus our research and initiatives in the following areas. firstly, we will further deepen our study of ontoulp classes to further increase their precision. we will also examine the search personalization of oer based on uses and practices of algorithms in the ontoulp.62 for example, by relying on newer version of the ontology we will identify the topics of interest, which may interest a specific user-learner. we will implement this information technology and libraries june 2022 ontology for the user-learner profile | kordahi 16 newer version in some thematic digital universities to perform technical tests. secondly, we will conduct qualitative and quantitative studies to analyze participants’ behavior while using ontoulp and its application program, in the context of thematic digital universities. for example, we will examine how many participants would choose to use the ontoulp and psul as well as how many wouldn’t (e.g., the usefulness of ontologies to participants). we will analyze the behavior of individuals with digital personae and make connections between their searches for oer.63 we will study their profiles, behaviors, and interests to ultimately suggest oer (e.g., the use of recommendation systems). we will also analyze how participants’ behavior and feedback may affect future findings. participants would be previously selected to contribute to these studies. thirdly, we will study the effects of ontoulp and psul practices on the thematic digital universities. this study will concern an analysis of the thematic digital universities’ search engines and users-learners’ needs. for example, exploratory research will allow us to better understand user-learners’ informational needs and expectations when using the oer search engines. we will analyze the design of oer search engines considering these informational needs and expectations. we will then utilize and integrate these findings to suggest alternatives to the thematic digital universities to further improve these search engines. acknowledgments we thank the digital university association and thematic digital universities for their elaborate and enlightening explanations concerning the platforms. we thank the

reality? abigail j. mcdermott information technology and libraries | march 2012 7 abstract this paper provides a brief overview of the current state of copyright law in the united states, focusing on the negative impacts of these policies on libraries and patrons. the article discusses four challenges current copyright law presents to libraries and the public in general, highlighting three concrete ways intellectual property law interferes with digital library services and systems. finally, the author suggests that a greater emphasis on copyright literacy and a commitment among the library community to advocate for fairer policies is vital to correcting the imbalance between the interests of the public and those of copyright holders. introduction in july 2010, the library community applauded when librarian of congress james h. billington announced new exemptions to the digital millennium copyright act (dmca). those with visual disabilities and the librarians who serve them can now circumvent digital rights management (drm) software on e-books to activate a read-aloud function.1 in addition, higher education faculty in departments other than film and media studies can now break through drm software to include high-resolution film clips in class materials and lectures. however, their students cannot, since only those who are pursuing a degree in film can legally do the same.2 that means that english students who want to legally include high-resolution clips from the critically acclaimed film sense and sensibility in their final projects on jane austin’s novel will have to wait another three years, when the librarian of congress will again review the dmca. the fact that these new exemptions to the dmca were a cause for celebration is one indicator of the imbalanced state of the copyright regulations that control creative intellectual property in this country. as the consumer-advocacy group public knowledge asserted, “we continue to be disappointed that the copyright office under the digital millennium copyright act can grant extremely limited exemptions and only every three years. this state of affairs is an indication that the law needs to be changed.”3 this paper provides a brief overview of the current state of u.s. copyright law, especially developments during the past fifteen years, with a focus on the negative impact these policies have had and will continue to have on libraries, librarians, and the patrons they serve. this paper does not provide a comprehensive and impartial primer on copyright law, a complex abigail j. mcdermott (ajmcderm@umd.edu) is graduate research associate, the information policy and access center (ipac), and masters candidate in library science, university of maryland, college park. mailto:ajmcderm@umd.edu copyright: regulation out of line with our digital reality | mcdermott 8 and convoluted topic, instead identifying concerns about the effects an out-of-balance intellectual property system is having on the library profession, library services, and creative expression in our digital age. as with any area of public policy, the battles over intellectual property issues create an every fluctuating copyright environment, and therefore, this article is written to be current with policy developments as of october 2011. finally, this paper recommends that librarians seek to better educate themselves about copyright law, and some innovative responses to an overly restrictive system, so that we can effectively advocate on our own behalf, and better serve our patrons. the state of u.s. copyright law copyright law is a response to what is known as the “progress clause” of the constitution, which charges congress with the responsibility “to promote the progress of science and the useful arts . . . to this end, copyright assures authors the right to their original expression, but encourages others to build freely upon the ideas and information conveyed by a work.”4 fair use, a statutory exception to u.s. copyright law, is a complex subject, but a brief examination of the principle gets to the heart of copyright law itself. when determining fair use, courts consider 1. the purpose and character of the use; 2. the nature of the copyrighted work; 3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and 4. the effect of the use upon the potential market for the copyrighted work.5 while fair use is an “affirmative defense” to copyright infringement,6 invoking fair use is not the same as admitting to copyright infringement. teaching, scholarship, and research, as well as instances in which the use is not-for-profit and noncommercial, are all legitimate examples of fair use, even if fair use is determined on a case-by-case basis.7 despite the byzantine nature of copyright law, there are four key issues that present the greatest challenges and obstacles to librarians and people in general: the effect of the dmca on the principle of fair use; the dramatic extension of copyright terms codified by the sonny bono copyright term extension act; the disappearance of the registration requirement for copyright holders; and the problem of orphan works. the digital millennium copyright act (dmca) the dmca has been controversial since its passage in 1998. title i of the dmca implements two 1996 world intellectual property organization (wipo) treaties that obligate member states to enforce laws that make tampering with drm software illegal. the dmca added chapter 12 to the u.s. copyright act (17 u.s.c. §§ 1201–1205), and it criminalized the trafficking of “technologies designed to circumvent access control devices protecting copyrighted material from unauthorized information technology and libraries | march 2012 9 copying or use.”8 while film studios, e-book publishers, and record producers have the right to protect their intellectual property from illegal pirating, the dmca struck a serious blow to the principle of fair use, placing librarians and others who could likely claim fair use when copying a dvd or pdf file in a catch-22 scenario. while the act of copying the file may be legal according to fair use, breaking through any drm technology that prevents that copying is now illegal.9 the sonny bono copyright term extension act while the copyright act of 1790 only provided authors and publishers with twenty-eight years of copyright protection, the sonny bono copyright term extension act of 1998 increased the copyright terms of all copyrighted works that were eligible for renewal in 1998 to ninety-five years after the year of the creator’s death. in addition, all works copyrighted on or after january 1, 1978, now receive copyright protection for the life of the creator plus seventy years (or ninety-five years from the date of publication for works produced by multiple creators).10 jack valenti, former president of the motion picture association of american, was not successful in pushing copyright law past the bounds of the constitution, which mandates that copyright be limited, although he did try to circumvent this constitutional requirement by suggesting that copyright terms last forever less one day.11 the era of automatic copyright registration perhaps the most problematic facet of modern u.s. copyright law appears at first glance to be the most innocuous. the copyright act of 1976 did away with the registration requirement established by the copyright act of 1790.12 that means that any creative work “fixed in any tangible medium of expression” is automatically copyrighted at the moment of its creation.13 that includes family vacation photos stored on a computer hard drive; they are copyrighted and your permission is required to use them. the previous requirement of registration meant authors and creators had to actively register their works, so anything that was not registered entered the public domain, replenishing that important cultural realm.14 now that copyright attaches at the moment an idea is expressed through a cocktail napkin doodle or an outline, virtually nothing new enters the public domain until its copyright term expires—at least seventy years later. in fact, nothing new will enter the public domain through copyright expiration until 2019. until then, the public domain is essentially frozen in the year 1922.15 the problem of orphan works in addition, the incredibly long copyright terms that apply to all books, photographs, and sound recordings have created the problem of orphan works. orphan works are those works that are under copyright protection, but whose owners are difficult or impossible to locate, often due to death.16 these publications are problematic for researchers, librarians, and the public in general: orphan works are perceived to be inaccessible because of the risk of infringement liability that a user might incur if and when a copyright owner subsequently appears. consequently, many works that are, copyright: regulation out of line with our digital reality | mcdermott 10 in fact, abandoned by owners are withheld from public view and circulation because of uncertainty about the owner and the risk of liability.17 if copyright expired with the death of the author, or if there were a clause that would allow these works to pass into the public domain if the copyright holder’s heirs did not actively renew copyright for another term, then these materials would be far less likely to fall into legal limbo. currently, many are protected despite the fact that acquiring permission to use them is all but impossible. a study of orphan works in the collections of united kingdom public sector institutions found that these works are likely to have little commercial value, but high “academic and cultural significance,” and when contacted, these difficult-to-trace rights holders often grant permission for reproduction without asking for compensation.18 put another way, orphan works are essentially “locking up culture and other public sector content and preventing organizations from serving the public interest.”19 the row that arose in september 2011 between the hathitrust institutions and the authors guild over the university of michigan’s orphan works digitization project, with j. r. salamanca’s longout-of-print 1958 novel the lost country serving as the pivot point in the dispute, is an example of the orphan works problem. the fact that university of michigan associate university librarian john price wilkin was forced to assure the public that “no copyrighted books were made accessible to any students” illustrates the absurdity in arguing over whether it’s right to digitize books that are no longer even accessible in their printed form.20 libraries, digitization, and copyright law: the quiet crisis while one can debate if u.s. copyright law is still oriented toward the public good, the more relevant question in this context is the effect copyright law has on the library profession. drm technology can get in the way of serving library patrons with visual disabilities and every library needs to place a copyright disclaimer on the photocopiers, but how much more of a stumbling block is intellectual property law to librarians in general, and the advance of library systems and technology in particular? the answer is undeniably that current u.s. copyright legislation places obstacles in the way of librarians working in all types of libraries. while there are many ways that copyright law affects library services and collections in this digital area, three challenges are particularly pressing: the problem of ownership and licensing of digital content or collections; the librarian as de facto copyright expert; and copyright law as it relates to library digitization programs generally, and the google book settlement in particular. digital collections: licenses replace ownership in the past, people bought a book, and they owned that copy. there was little they could accidentally or unknowingly do to infringe on the copyright holder’s rights. likewise, when physical collections were their only concern, librarians could rely on sections 108 and 109 of the copyright law to protect them from liability when they copied a book or other work and when they loaned materials in their collections to patrons.21 today, we live partly in the physical world and https://exch.mail.umd.edu/owa/webreadyviewbody.aspx?t=att&id=rgaaaadxslsgbeewtj9q0yhnkit2bwboujgpo3tvsou0x%2bkwiyfqalrqjtslaaboujgpo3tvsou0x%2bkwiyfqapiuledyaaaj&attid0=eacjse6zzphuq6qbfqvhbhu8&attcnt=1&pn=1#footnote19#footnote19 information technology and libraries | march 2012 11 partly in the digital world, reaching out and connecting to each other across fiber optic lines in the same way we once did around the water cooler. likewise, the digital means of production are widely distributed. in a multimedia world, where sharing an informative or entertaining video clip is as easy as embedding a link onto someone’s facebook wall, the temptation to infringe on rights by distributing, reproducing, or displaying a creative work is all too common, and all too easy.22 many librarians believe that disclaimers on public-access computer terminals will protect them from lawsuit, but they do not often consider placing such disclaimers on their cd or dvd collections. yet a copyright holder would not have to prove the library is aware of piracy to accuse the library of vicarious infringement of copyright. the copyright holder may even be able to argue that the library sees some financial gain from this piracy if the existence of the material that is being pirated serves as the primary reason a patron visits the library.23 even the physical cd collection in the public library can place the institution in danger of copyright infringement; yet the copyright challenges raised by cutting-edge digital resources, like e-books, are undoubtedly more complicated. e-books are replacing traditional books in many contexts. like most digital works today, e-books are licensed, not purchased outright. the problem licensing presents to libraries is that licensed works are not sold, they are granted through contracts, and contracts can change suddenly and negate fair-use provisions of u.s. copyright law.24 while libraries are now adept at negotiating contracts with subscription database providers, e-books are in many ways even more difficult to manage, with many vendors requiring that patrons delete or destroy the licensed content on their personal e-readers at the end of the lending period.25 the entire library community was rocked by harpercollins’s february 2011 decision to limit licenses on e-books offered through library ebook vendors like overdrive to twenty-six circulations, with many librarians questioning the publisher’s assertion that this seemingly arbitrary limitation is related to the average lifespan of a single print copy.26 license holders have an easy time arguing that any use of their content without paying fees is a violation of their copyright. that is not the case when a fair use argument is justified, and while many in the library community may acquiesce to these arguments, “in recent cases, courts have found the use of a work to be fair despite the existence of a licensing market.”27 when license agreements are paired with drm technology, libraries may find themselves managing thousands of micropayments to allow their users to view, copy, move, print, or embed, for example, the pdf of a scholarly journal article.28 in the current climate of reduced staff and shrinking budgets, managing these complex licensing agreements has the potential to cripple many libraries. the librarian as accidental copyright czar during a special libraries association (sla) q&a session on copyright law in the digital age, the questions submitted to the panel came from librarians working in hospitals, public libraries, academic libraries, and even law libraries. librarians are being thrust into the position of de facto copyright expert. one of the speakers mentioned that she must constantly remind the lawyers at copyright: regulation out of line with our digital reality | mcdermott 12 the firm she works for that they should not copy and paste the full text of news or law review journal articles into their e-mails, and instead, they should send a link. the basis of her argument is the third factor of fair use mentioned earlier: the amount or substantiality of the portion of the copyrighted work being used.29 since fair use is not a “bright line” principle, the more factors you have on your side the better when you are using a copyrighted work without the owners express permission.30 librarians working in any institution must seek express permission from copyright holders for any video they wish to post, or embed, on library-managed websites. e-reserves and streaming video, mainstays of many educators and librarians seeking to capture the attention of this digital generation, have become bright red targets for litigious copyright holders who want to shrink the territory claimed under the fair-use banner even further. many in the library community are aware of the georgia state university e-reserves lawsuit, cambridge university press et al. v. patton, in which a group of academic publishers have accused the school of turning its e-reserves system into a vehicle for intentional piracy.31 university librarians are implicated for not providing sufficient oversight. it has come to light that the association of american publishers (aap) approached other schools, including cornell, hofstra, syracuse, and marquette, before filing a suit against georgia state. generally, the letters come from aaps outside counsel and are accompanied by “the draft of a federal court legal complaint that alleges copyright infringement.”32 the aap believes that e-reserves are by nature an infringement of copyright law, so they demand these universities work with their association to draft guidelines for electronic content that support aaps “cost-per-click theory of contemporary copyright: no pay equals no click.”33 it seems that georgia state was not willing to quietly concede to aap’s view on the matter, and they are now facing the association in court.34 a decision in this case was pending at the time this article went to press. the case brought by the association for information and media equipment (aime) against ucla is similar, except it focuses on the posting of videos so they can be streamed by students on password-protected university websites that do not allow the copying or retention of the videos.35 ucla argued that the video streaming services for students are protected by the technology education and copyright harmonization (teach) act of 2002, which is the same act that allows all libraries to offer patrons online access to electronic subscription databases off-site through a user-authentication system.36 in addition, ucla argues that it is simply allowing its students to “time shift” these videos, a practice deemed not to infringe on copyright law by the supreme court in its landmark sony corp. v. universal city studios, inc. decision of 1984.37 the american library association (ala), association of research libraries (arl), and the association of college and research libraries (acrl) jointly published an opinion supporting ucla in this case. many in the wider library community sympathized with ucla’s library administrators, who cite budget cuts that reduced hours at the school’s media laboratory as one reason they must now offer students a video-streaming option.38 in the end, the case was dismissed, mostly due to the lack of standing aime had to bring the suite against ucla, a state agency, in federal court. while the judge did not https://exch.mail.umd.edu/owa/webreadyviewbody.aspx?t=att&id=rgaaaadxslsgbeewtj9q0yhnkit2bwboujgpo3tvsou0x%2bkwiyfqalrqjtslaaboujgpo3tvsou0x%2bkwiyfqapiuledyaaaj&attid0=eacjse6zzphuq6qbfqvhbhu8&attcnt=1&pn=1#footnote30#footnote30 information technology and libraries | march 2012 13 expressly rule on the fair-use argument ucla made, the ruling did confirm that streaming is not a form of video distribution and that the public-performance argument ucla made regarding the videos was not invalidated by the fact that they made copies of the videos in question.39 digitization programs and the google book settlement librarians looking to digitize print collections, either for preservation or to facilitate online access, are also grappling with the copyright monopoly. librarians who do not have the time or resources to seek permission from publishers and authors before scanning a book in their collection cannot touch anything published after 1922. librarylaw.com provides a helpful chart directed at librarians considering digitization projects, but the overwhelming fine print below the chart speaks to the labyrinthine nature of copyright.40 the google book settlement continues to loom large over both the library profession and the publishing industry. at the heart of debate is google’s library project, which is part of google book search, originally named google print.41 the library project allows users to search for books using google’s algorithms to provide at its most basic a “snippet view” of the text from a relevant publication. authors and publishers could also grant their permission to allow a view of select sample pages, and of course if the book is in the public domain, then google can make the entire work visible online.42 in all cases, the user will see a “buy this book” link so that he or she could purchase the publication from online vendors on unrelated sites.43 google hoped to sidestep the copyright permission quandary for a digitization project of this scale, announcing that it would proceed with the digitization of cooperative library collections and that it would be the responsibility of publishers and authors to actively opt out or vocalize their objection to seeing their works digitized and posted online.44 google attempted to turn the copyright permissions process on its head, which was the basis of the class action lawsuit authors guild v. google inc.45 before the settlement was reached, google pointed to kelly v. arriba soft corp as proof that the indexing functions of an internet search engine constitute fair use. in that 2002 case, the ninth circuit court of appeals found that a website’s posting of thumbnail images, or “imprecise copies of low resolution, scaled down images,” constitutes fair use, and google argued its “snippet view” function is equivalent to a thumbnail image.46 however, judge denny chin rejected the google book settlement in march 2011, citing the fact that google would in essence be “exploiting books without the permission of copyright owners” and could also establish a monopoly over the digitized books market. the decision did in the end hinge on the fact that google wanted to follow an opt-out program for copyright holders rather than an affirmative opt-in system.47 the google book settlement was dismissed without prejudice, leaving the door open to further negotiations between the parties concerned. going forward, the library community should be concerned with how google will handle orphan works and how its index of digitized works will be made available to libraries and the public. the 2008 settlement granted google the nonexclusive right to digitize all books published before january 5, 2009, and in exchange, google would have https://exch.mail.umd.edu/owa/webreadyviewbody.aspx?t=att&id=rgaaaadxslsgbeewtj9q0yhnkit2bwboujgpo3tvsou0x%2bkwiyfqalrqjtslaaboujgpo3tvsou0x%2bkwiyfqapiuledyaaaj&attid0=eacjse6zzphuq6qbfqvhbhu8&attcnt=1&pn=1#footnote40#footnote40 copyright: regulation out of line with our digital reality | mcdermott 14 “paid 70% of the net revenue earned from uses of google book search in the united states to rights holders.”48 in addition, google would have established the book rights registry to negotiate with google and others seeking to “digitize, index or display” those works on behalf of the rights holders.49 approval of the settlement would have allowed google to move forward with plans to expand google book search and “to sell subscriptions to institutions and electronic versions of books to individuals.”50 the concern that judge denny chin expressed over a potential google book monopoly was widespread among the library community. while the settlement would not have given google exclusive rights to digitize and display these copyrighted works, google planned to ensure via the settlement that it would have received the same terms the book rights registry negotiated with any third-party digital library, while also inoculating itself against the risk of any copyright infringement lawsuits that could be filed against a competitor.51 that would have left libraries vulnerable to any subscription price increases for the google books service.52 libraries should carefully watch the negotiations around any future google books settlement, paying attention to a few key issues.53 there was considerable concern that under the terms of the 2008 settlement, even libraries participating in the google books library project would need to subscribe to the service to have access to digitized copies of the books in their own collections.53 many librarians also vocalized their disappointment in google’s abandonment of its fair-use argument when it agreed to the 2008 settlement, which, if it succeeded, would have been a boon to nonprofit, library-driven digitization programs.54 finally, many librarians were concerned that google’s book rights registry was likely to become the default rights holder for the orphan works in the google books library, and that claims that google books is an altruistic effort to establish a world library conceals the less admirable aim of the project—to monetize out-of-print and orphan works.55 librarians as free culture advocates: implications and recommendations our digital nation has turned copyright law into a minefield for both librarians and the public at large. intellectual property scholar lawrence lessig failed in his attempt to argue before the supreme court that the sonny bono copyright term extension act was an attempt to regulate free speech and therefore violated the first amendment.56 but many believe that our restrictive copyright laws at least violate the intent of the progress clause of the constitution, if not the first amendment: “unconstrained access to past works helps determine the richness of future works. inversely, when past works are inaccessible except to a privileged minority, future works are impoverished.”57 while technological advances have placed the digital means of production into the hands of the masses, intellectual property law is leading us down a path to self-censorship.58 as the profession “at the heart of both the knowledge economy and a healthy democracy,”59 it is in our best interest as librarians to recognize the important role we have to play in restoring the balance to copyright law. to engage in the debate over copyright law in the digital age, the library community needs to educate itself and advocate for our own self-interests, focusing on three key areas: https://exch.mail.umd.edu/owa/webreadyviewbody.aspx?t=att&id=rgaaaadxslsgbeewtj9q0yhnkit2bwboujgpo3tvsou0x%2bkwiyfqalrqjtslaaboujgpo3tvsou0x%2bkwiyfqapiuledyaaaj&attid0=eacjse6zzphuq6qbfqvhbhu8&attcnt=1&pn=1#footnote50#footnote50 information technology and libraries | march 2012 15 1. copyright law in the classroom and at the conference. we must educate new and seasoned librarians on the nature of copyright law, and the impact it has on library practice and systems. library schools must step up to the plate and include a thorough overview of copyright law in their library science curriculum. while including copyright law in a larger legal-issues class is acceptable, the complexity of current u.s. copyright law demonstrates that this is not a subject that can be glossed over in a single lecture. furthermore, there needs to be a stronger emphasis on continuing education and training on copyright law within the library profession. the sla offers a copyright certificate program, but the reach of such programs is not wide enough. copyright law, and the impacts current policy has on the library profession, must be prominently featured at library conferences. the university of maryland university college’s center for intellectual property offers an online community forum for discussing copyright issues and policies, but it is unclear how many librarians are members.60 2. librarians as standard-bearers for the free culture movement. while the library copyright alliance, to which the ala, arl, and acrl all belong, files amicus briefs in support of balanced copyright law and submits comments to wipo, the wider library community must also advocate for copyright reform, since this is an issue that affects all librarians, everywhere. as a profession, we need to throw our collective weight behind legislative measures that address the copyright monopoly. there have been a number of unfortunate failures in recent years. s. 1621, or the consumers, schools, and libraries digital management awareness act of 2003, attempted to address a number of drm issues, including a requirement that access controlled digital media and electronics include disclosures on the nature of the drm technology in use.61 h.r. 107, the digital media consumers rights act of 2003, would have amended the dmca to allow those researching the technology to circumvent drm software while also eliminating the catch-22 that makes circumventing drm software for fair-use purposes illegal. the balance act of 2003 (h.r. 1066) included provisions to expand fair use to the act of transmitting, accepting, and saving a copyrighted digital work for personal use. all of this legislation died in committee, as did h.r. 5889 (orphan works act of 2008) and s. 2913 (shawn bentley orphan works act of 2008). both bills would have addressed the orphan works dilemma, clearly spelling out the steps one must take to use an orphan work with no express permission from the copyright holder, without fear of a future lawsuit. could a show of support from the library community have saved these bills? it is impossible to know, but it is in our best interest to follow these legislative battles in the future and make sure our voice is heard. 3. libraries and the creative commons phenomenon. in addition, librarians need to take part in the creative commons (cc) movement by actively directing patrons towards this world of digital works that have clear, simple use and attribution requirements. creative commons was founded in 2001 with the support of the center for the study of the public domain at duke university school of law.62 the movement is essentially about free culture, and the idea that many people want to share their creative works and allow others to use or build off of their efforts easily and without seeking their permission. it is not intended to supplant copyright law, and lawrence copyright: regulation out of line with our digital reality | mcdermott 16 lessing, one of the founders of creative commons, has said many times that he believes intellectual property law is necessary and that piracy is inexcusable.63 instead, a cc license states in clear terms exactly what rights the creator reserves, and conversely, what rights are granted to everyone else.64 as lawrence lessig explains, you go to the creative commons website (http://creativecomms.org); you pick the opportunity to select a license: do you want to permit commercial uses or not? do you want to allow modifications or not? if you allow modifications, do you want to require a kind of copyleft idea that other people release the modifications under a similarly free license? that is the core, and that produces a license.65 there are currently six cc licenses, and they include some combination of the four license conditions defined by creative commons: attribution (by), share alike (sa), noncommercial (nc), and no derivatives (nd).66 each of the four conditions is designated by a clever symbol, and the six licenses display these symbols after the creative commons trademark itself, two small c’s inside a circle.67 there are “hundreds of millions of cc licensed works” that can be searched through google and yahoo, and some notable organizations that rely on cc licenses include flickr, the public library of science, wikipedia, and now whitehouse.gov.68 all librarians not already familiar with this approach need to educate themselves on cc licenses and how to find cc licensed works.69 while librarians must still inform their patrons about the realities of copyright law, it is just as important to direct patrons, students, and colleagues to cc licensed materials, so that they can create the mash-ups, videos, and podcasts that are the creative products of our web 2.0 world.70 the creative commons system is not perfect, and “creative commons gives the unskilled an opportunity to fail at many junctures.”71 yet that only speaks to the necessity of educating the library community about the “some rights reserved” movement, so that librarians, who are already called upon to understand traditional copyright law, are also educating our society about how individuals can protect their intellectual property while preserving and strengthening the public domain. conclusion the library community can no longer afford to consider intellectual property law as a foreign topic appropriate for law schools but not library schools. those who are behind the slow extermination of the public domain rely on the complexity of copyright law, and the misunderstanding of the principle of fair use, to make their arguments easier and to brow beat libraries and the public into handing over the rights the constitution bestows on everyone. librarians need to engage in the debate over copyright law to retain control over their collections, and to better serve their patrons. in the past, the library community has not hesitated to stand up for the freedom of speech and self-expression, whether it means taking a stand against banning books from school libraries or fighting to repeal clauses of the usa patriot act. today’s library patrons are not just information consumers—they are also information producers. therefore it is just as critical for librarians to advocate for their creative rights as it is for them to defend their freedom to read.

information technology and libraries | march 2012 17 the internet has become such a strong incubator of creative expression and innovation that the innovators are looking for a way to shirk the very laws that were designed to protect their interests. in the end, the desire to create and innovate seems to be more innate than those writing our intellectual property laws expected. perhaps financial gain is less of a motivator than the pleasure of sharing a piece of ourselves and our worldview with the rest of society. whether that’s the case or not, what is clear is that if we do not roll back legislation like the sonny bono copyright term extension act and the dmca so as to save the public domain, the pressure to create outside the bounds of the law is going to turn more inventors and artists into anarchists, threatening the interests of reasonable copyright holders. as librarians, we must curate and defend the creative property of the established, while fostering the innovative spirit of the next generation. as information, literature, and other creative works move out of the physical world, and off the shelves, into the digital realm, librarians need to do their part to ensure legislation is aligned with this new reality. if we do not, our profession may suffer first, but it will not be the last casualty of the copyright wars. references 1. beverly goldberg, “lg

chat reference and library-wide instant messaging network ian chan, pearl ly, and yvonne meulemans information technology and libraries | september 2012 4 abstract openfire is an open-source instant messaging (im) network and a single unified application that meets the needs of chat reference and internal communication. in fall 2009, the california state university san marcos (csusm) library began using openfire and other jive software im technologies to simultaneously improve our existing im-integrated chat reference software and implement an internal im network. this case study describes the chat reference and internal communications environment at the csusm library and the selection, implementation, and evaluation of openfire. in addition, the authors discuss the benefits of deploying an integrated im and chat reference network. introduction instant messaging (im) has become a prevalent contact point for library patrons to get information and reference help, commonly known as chat reference or virtual reference. however, im can also offer a unique method of communication between library staff. librarians are able to rapidly exchange information synchronously or asynchronously in an informal way. im provides another means of building relationships within the library organization and can improve teamwork. many different chat-reference software packages are widely used by libraries, including questionpoint, meebo, and libraryh3lp. less commonly used is openfire (www.igniterealtime.org/projects/openfire), an open-source im network and a single unified application that uses the extensible messaging and presence protocol (xmpp), a widely adopted open protocol for im. since 2009, the california state university san marcos (csusm) kellogg library has used openfire for chat reference and internal im communication. openfire was relatively easy to set up and administer by the web development librarian. librarians and library users have found the im interface to be intuitive. in addition to helpful chat reference features such as statistics capture, queues, transfer, linking to meebo widgets, openfire offers the unique capability to host an internal im network within the library. ian chan (ichan@csusm.edu) is web development librarian, california state university san marcos, pearl ly (pmly@pasadena.edu) is access services & emerging technologies librarian, pasadena community college, pasadena, and yvonne meulemans (ymeulema@csusm.edu) is information literacy program coordinator, california state university san marcos, california. extending im beyond the reference desk | chan, ly, and meulemans 5 in this article, the authors present a literature review on im as a workplace communication tool and its successful use in libraries for chat reference services. a case study on the selection, implementation, and evaluation of openfire for use in chat reference and as an internal network will be discussed. in addition, survey results on the library staff use of the internal im network and its implications for collaboration and increased communication are shared. literature review although there is a great deal of literature on im for library reference services, publications on the use of im in libraries for internal communications do not appear in the professional literature. a review of library and information science (lis) literature has revealed very limited work on this aspect of instant messaging. however, a wider literature review in the fields of communications, computer science, and business, indicates there is growing interest in studying the benefits of im within organizations. instant messaging in the workplace in the workplace, im can offer a cost-effective means of connecting in real-time and may increase communication effectiveness between employees. it offers a number of advantages over email, telephone, and face-to-face that we will discuss further in the following section. within the academic library, im offers the possibility of not only improving access to librarians for research help but also provides the opportunity to enhance communication and collaboration throughout the entire organization. research findings indicate that im allows coworkers to maintain a sense of connection and context that is different from email, face-to-face (ftf), and phone conversations.1 each im conversation is designed to display as a single textual thread with one window per conversation. the contributions from each person in the discussion are clearly indicated and it is easy to review what has been said. this design supports the intermittent reconnection of conversation and in contrast to email, “intermittent instant messages were thought to be more immersive and to give more of a sense of a shared space and context than such email exchanges.”2 through the use of im, coworkers gain a highly interactive channel of communication that is not available via other methods of communication.3 phone and ftf conversations are two of the most common forms of interruption within the workplace.4 however, garrett and danziger found that “instant messaging in the workplace simultaneously promotes more frequent communications and reduces interruptions.”5 participants reported they were better able to manage disruptions using im and that im did not increase their communication time. the findings of this study revealed that some communication that otherwise may have occurred over email, by telephone, or in-person were instead delivered via im. this likely contributed to the reduced interruptions because im does not require full and immediate attention unlike a phone call or face-to-face communication. in addition, im study participants reported the ability to negotiate their availability through postponing conversations, information technology and libraries | september 2012 6 and these findings support earlier studies suggesting im is less intrusive than traditional communication methods for determining availability of coworkers.6 a number of research studies show that im improves teamwork and is useful for discussing complex tasks. huang, hung, and chen compared the effectiveness of email and im and the number of new ideas; they found that groups utilizing im generated more ideas than the email groups.7 they suggested that the spontaneous and rapid interchanges typical of im facilitates brainstorming between team members. the information that is uniquely visible through im and the ease of sending messages help create opportunities for spontaneous dialog. this is supported by a study by quan-haase, cothrel, and wellman, which found im promotes team interaction by indicating the likelihood of a faster response.8 ou et al. also suggest im has “potential to empower teamwork by establishing social networks and facilitating knowledge sharing among organizational members.”9 im can enhance the social connectedness of coworkers through its focus on contact lists and instant, opportunistic interactivity. the informal and personalized nature of im allows workers to build relationships while promoting the sharing of information. cho, trier, and kim suggest that the use of im as a communication tool encourages unplanned virtual hallway discussions that may be difficult for those located in different parts of a building, campus, or in remote locations.10 im can build relationships between teams and organizations where members are in physically separated locations. however, cho, trier, and kim also note that im is more successful in building relationships between coworkers who already have an existing relationship. wu et al. argue that by helping to build the social network within the organization, instant messaging can contribute to increased productivity.11 several studies have cautioned that im, like other forms of communication, requires organizational guidelines on usage and best practices. mahatanankoon suggests that productivity or job satisfaction may decrease without policies and workplace norms that guide im use.12 other research indicates that personality, employee status, and working style may affect the usefulness of im for individual employees.13 some workers may find the multitasking nature of im to work in their favor while those who prefer sequential task completion may find im disruptive. the hierarchy of work relationships and the nature of managerial styles are likely to have an impact on the use of im as well. while there are no research findings associated with the use of im for internal communication within libraries, there are articles encouraging its use. breeding writes of the potential for im to bring about “a level of collaboration that only rarely occurs with the store-and-forward model of traditional e-mail.”14 fink provides a concise introduction to the advantages of using internal im for communication between library staff.15 in addition, he provides an overview of the implementation and success of the openfire-based im network at mcmaster university. extending im beyond the reference desk | chan, ly, and meulemans 7 success of chat reference in libraries im-based chat reference gives libraries the means to more easily offer low-cost delivery of synchronous, real-time research assistance to their users, commonly referred to as “chat reference.” although libraries have used im for the last decade and many currently subscribe to questionpoint, a collaborative virtual reference service through oclc, two newer online services helped propel the growth of im-based chat reference. first available in 2006, the web-based meebo (www.meebo.com) made it much easier to use im for localized chat reference because library patrons were no longer required to have accounts on a proprietary network, such as aol or yahoo, to communicate with librarians.16 instead, meebo provided web widgets that allowed users to chat via the web browser. libraries could easily embed these widgets throughout their website and unlike questionpoint, meebo is free and does not require a subscription. librarians could answer questions using either their account on meebo’s website or by logging-in with a locally installed instant messaging client. in comparison to im-based chat reference, a number of libraries also found questionpoint difficult to use due to its complexity and awkward interface.17 in 2008, libraryh3lp (http://libraryh3lp.com) pushed the growth of im-based chat reference even further because it offered a low-cost, library-specific service that required little technical expertise to implement and operate. libraryh3lp improved on the meebo model by adding features such as queues, multi-user accounts, and assessment tools.18 im adds a more informal means of interaction that helps librarians build relationships with their users. several recent studies have shown that users respond positively to the use of im for chat reference. the illinois state university milner library found that switching from its older chat reference software to im increased transactions by 161 percent within one year.19 with the introduction of web-based im widgets pennsylvania state university library’s im-based chat reference grew from 20 percent to 60 percent of all virtual reference (vr), which includes email reference, in one year.20 a 2010 study of vr and im service at the university of guelph library found 71 percent user satisfaction with im compared to 70 percent satisfaction with vr overall.21 im use in academic libraries has become ubiquitous, and other types of libraries also use im to communicate with library patrons. case study california state university, san marcos (csusm) is a mid-size public university with approximately 9,500 students. csusm is a commuter campus with the majority of students living in north county san diego and offers many online or distance courses at satellite campuses. the csusm kellogg library has a robust chat reference service that is used by students on and off campus. the library has about forty-five employees including librarians, library administrators, and library assistants. the following section will discuss the meebo chat reference pilot, selection of openfire to replace meebo, implementation and customization of openfire, and evaluation of openfire for chat reference by librarians and as an internal network for all library personnel. information technology and libraries | september 2012 8 meebo chat reference pilot to examine the feasibility of using im for chat reference at csusm, the reference librarians initiated a pilot program using meebo (2008–9). a meebo widget was placed on the library’s homepage, the ask a librarian page, and on library research guides. within the first year of the pilot project, chat reference grew to more than 41 percent of all reference transactions.22 based on responses to user satisfaction surveys, 85 percent indicated they would recommend chat reference to other students, and 69 percent said they preferred it to other forms of reference services. chat reference is now an integral part of the library’s research assistance program, and im has become a permanent access point for students to contact reference librarians. although the new im service was successful, the pilot program uncovered a number of key shortcomings with meebo when used for chat reference; these shortcomings are documented in a case study by meulemans et al.23 these findings matched problems reported by other libraries who used meebo in their reference services.24 meebo is most suited for individual users who communicate one-to-one via im. for example, meebo chat widgets are specific to each meebo user, and it is not possible to share a single widget between multiple librarians. in addition, features such as message queues and message transfers, invaluable for managing a heavily used chat reference service, are not available in meebo. those features are essential for working with multiple, simultaneous incoming im messages, a common occurrence in virtual reference. other missing features included the lack of built-in transcript retention and lack of automated usage statistics.25 selecting openfire based on the need for a more robust chat reference system, the csusm reference librarians and the web development librarian explored other im options, especially open-source software. the web development librarian had previous experience using openfire at the university of alaska anchorage, for an internal library im network and investigated its capabilities to replace meebo as a chat reference tool. the desire to replace meebo for chat reference at csusm also provided the opportunity to pilot an internal im network. openfire, part of the suite of open-source instant messaging tools from jive software, was the only application that could easily fulfill both roles and offered a number of features that made it highly preferable when compared to other im-based chat reference systems. of its many features, one of the most valuable was the integration between openfire user accounts and our campus email system. being able to tap into the university’s email system meant automated configuration and updating of all staff accounts and contact lists. this removed the burden of individual account maintenance associated with external services such as meebo, libraryh3lp, and questionpoint. openfire supports internal im networks at educational institutions such as the university of pennsylvania, central michigan university, and university of california, san francisco. extending im beyond the reference desk | chan, ly, and meulemans 9 openfire could meet our im chat reference needs because it includes the fastpath plugin, a complete web-based chat management system available at www.igniterealtime.org/projects/openfire/plugins.jsp. this robust system incorporates important features such as message queues, message transfer, statistics, and canned messages. james cook university library in australia also chose to use openfire with fastpath plugin as its chat reference solution based on their need for those features.26 other institutions using fastpath and openfire in the role of chat reference or support include the university of texas, the oregon/ohio multistate virtual reference consortium, mozilla.com, and the university of wisconsin. when reviewing chat reference solutions, we considered the possibility of using chat modules available through drupal (http://drupal.org), the web content management system (cms) for our library website. the primary advantage of that option was complete integration with the library website and intranet. further analysis of the drupal option revealed that the available chat modules where too basic for our needs and that reconfiguration of our intranet and website to incorporate a workable chat reference system would require extensive time. in comparison to the implementation time associated with deploying the openfire system, using drupal-based chat modules did not provide a favorable cost-benefit ratio. while the proprietary libraryh3lp offered similar functionality for chat reference, its inability to integrate with our email system was clearly a deficit when compared to openfire. in libraryh3lp, it is necessary to create accounts for all library personnel in chat reference. fastpath does not have that requirement if you integrate openfire with your organization’s lightweight directory access protocol (ldap) directory. instead, the system will automatically create accounts for all library staff. furthermore, the administrative options and interface for libraryh3lp also did not compare favorably with that of fastpath. the fastpath interface for assigning users is more intuitive and the system generates a customizable chat initiation form for each workgroup (figures 1 and 2). oregon’s l-net and ohio’s knowitnow24x7 offer information about software requirements and an online demonstration of spark/fastpath.27 information technology and libraries | september 2012 10 figure 1. fastpath chat initiation form for csusm research help desk figure 2. fastpath chat initiation form for csusm media library for our requirements, openfire was clearly superior to the available systems for chat reference. its relatively simple deployment requirements and ease of setup helped make it our first choice for building a combined im network and chat reference system. in the following section, we will discuss the installation, customization, and assessment of our openfire implementation. openfire installation and configuration the openfire application is a free download from ignite realtime, a community of jive software. the program will run on any web server that has a windows, linux, or macintosh operating system. if configured as a self-contained application, openfire only requires java to be available on your web server. installation of the software is an automated process and system configuration is through a web-based setup guide. after the initial language selection form, the next step in the server configuration process is to enter the web server url and the ports through which the server will communicate with the outside world (figure 3). the third step provides fields for selecting the type of database to use with openfire and for inputting any information relating to your selection (figure 4). extending im beyond the reference desk | chan, ly, and meulemans 11 figure 3. openfire server settings screen figure 4. openfire database configuration form openfire uses a database to store information such as im network settings, user account information, and transcripts. database options include using an embedded database or connecting to an external database server. using the embedded database is the simpler option and is helpful if you do not have access to a database server. connecting to an external database server offers more control of the data generated by openfire and provides additional backup options. openfire works with a number of the more commonly used database servers such as mysql, postgresql, and microsoft sql server. in addition, oracle and ibm’s db2 are database options with additional free plugins from these vendors. we choose to use mysql because of our experience using it with other library web applications. if using the external database option, creating and configuring the external database before installing openfire is highly recommended. after choosing a database, the openfire configuration requires the selection of an authentication method for user accounts. one option is to use openfire’s internal authentication system. while the internal system is robust, it requires additional administrative support to manage the process of creating and maintaining user accounts. the recommended option is to connect openfire with your organization’s lightweight directory access protocol (ldap) directory (figure 5). ldap is a protocol that allows external systems to interact with the user information stored in an organization’s email system. using ldap with openfire is highly preferable because it simplifies access for your librarians and staff by automatically creating user accounts based on the information in your organization’s email system. library staff simply login with their work email or network account information; they are not required to create a new username and password. information technology and libraries | september 2012 12 figure 5. openfire ldap configuration form the last step in the configuration process is to grant system administrator access to the appropriate users. if using the ldap authentication method, you are able to select one or more users in your organization by entering their email id (the portion before the ampersand). the selected users will have complete access to all aspects of the openfire server. once the setup and configuration process is complete, the server is ready to accept im connections and route messages. reviewing the settings and options within the openfire system administration area is highly recommended. most libraries will likely want to adjust the configurations within the sections for server settings and archives. connecting the im network the second phase of the implementation process connected our library personnel with the im network using im software installed on their workstations. the openfire im server works with any multiprotocol im client (“multiprotocol” refers to support for simultaneous connections to multiple im networks) that provides options for configuring an xmpp or jabber account. some of the more popular im clients that offer this functionality include spark, trillian, miranda, and pidgin. based on our chat reference requirements, we choose to use spark (www.igniterealtime.org/projects/spark), an im client program designed to work specifically with the fastpath web chat service. spark comes with a fastpath plugin that enables users to receive and send messages to anyone communicating through the web-based fastpath chat widgets (more information on fastpath configuration is in the next section of this article). this plugin provides a tab for logging into a fastpath group and for viewing the status of the group’s message queues extending im beyond the reference desk | chan, ly, and meulemans 13 (figure 6). spark also includes many of the features offered by other im clients including built-in screen capture, message transfer, and group chat. figure 6. the fastpath plugin for spark library personnel were able to install spark on their own by downloading it from the ignite software website and launching the software’s installation package. the installation process is very simple and user-specific information is only required when spark is started for the first time. the fields required for login include the username and password of the user’s organizational email and the address of the im server. as part of our implementation process, we also provided library staff with recommendations regarding the selection and configuration of optional settings that might enhance their im experience. recommendations included auto-start of spark when loggingin to computer and the activation of incoming message signals, such as sound effects and pop-ups. on our openfire server, we had also installed the kraken gateway (http://kraken.blathersource.org) plugin to enable connections to external im networks. the gateway plugin works with spark to integrate library staff accounts on chat network such as google talk, facebook, and msn (an example of integrated networks is shown in figure 6.) by integrating meebo as well, librarians were able to continue using the meebo widgets they had embedded into their research guides and faculty profile pages. this allowed them to use spark to receive im messages rather than logging on to the meebo website. information technology and libraries | september 2012 14 configuring the fastpath plugin for chat reference a primary motivation for using openfire was the feature set available in the fastpath plugin. fastpath is a complete chat messaging system that includes workgroups, queues, chat widgets, and reporting. fastpath actually consists of two plugins that work together, fastpath service for managing the chat system and fastpath webchat for web-based chat widgets. both plugins are available as free downloads from the openfire plugins section of the ignite software website— www.igniterealtime.org/projects/openfire/plugins.jsp. to install fastpath, upload the its packages using the form in the plugins section of the openfire administrative interface. the plugins will automatically install and add a fastpath tab to the administrative main menu. the first step in getting started with the system is to create a workgroup and add members (figure 7). within each new workgroup, one or more queues are required to process and route incoming requests and each queue requires at least one “agent.” in fastpath, the term agent refers to those who will receive the incoming chat requests. figure 7. workgroup setup form in fastpath as work groups are created, the system automatically generates a chat initiation form which by default includes fields for name, email and question. administrators can remove, modify, and add any combination of field types including text fields, dropdown menus, multiline text areas, radio buttons, and check boxes. you may also configure the chat initiation form to require completion of some, all, or none of the fields. at csusm, our form (figures 1 and 2) includes name, question, email, and a dropdown menu for selecting the topic area of the user’s research and a field for the user to enter their question. the information in these fields allows us to quickly route incoming extending im beyond the reference desk | chan, ly, and meulemans 15 questions to the appropriate subject librarian. fastpath includes the ability to create routing rules that use the values submitted in the form to send messages to specific queues within a workgroup. in future, we may use the dropdown menu to automatically route questions to the subject specialist based on the student’s topic. there are two methods to make the fastpath chat widget available to the public. the standard approach embeds a presence icon on your webpage and provides automatic status updates. clicking on the icon displays the chat initiation form. for our needs we choose to embed the chat initiation form in our webpages (see appendix b for sample code). when the user submits the form, openfire routes the message to the next available librarian. on the librarian’s computer, the spark program plays a notification sound and displays a pop-up dialog. the pop-up dialog remains open until the librarian accepts the message, passes it on, or the time limit for acceptance is reached, in which case the message returns to the queue for the next available librarian. evaluation of openfire for enhanced chat reference the csusm reference librarians found fastpath and openfire to be much more robust than meebo for chat reference. the ability to keep chat transcripts and to retain metadata such as time stamps, duration of chats, and topic of research for each conversation is very helpful toward analyzing the effectiveness of chat research assistance and for statistical reporting. the automated recording of transcripts and metadata saved time when compared to meebo. using meebo, transcripts were manually copied into a microsoft word document and the tracking statistics of im interactions were kept in a shared excel spreadsheet. other useful features of fastpath were the capability of transferring of patrons to other librarians and having more than one librarian monitor incoming questions. furthermore, access to the database holding the fastpath data allowed us to build an intranet page to monitor real-time incoming im messages and their responses. however, some issues were encountered with the fastpath plugin when initiating chat connections. we experienced intermittent, random instances of dropped im connections and lost messages. while many of these lost connections were likely the result of user actions (accidentally closing the chat pop-up, walking away from the computer, etc.), others appear to have been due to problematic connections between the server and the user’s browser. to address these issues, we are now asking users to provide their email when they initiate a chat session. with user emails and our real-time chat monitoring system, we are able to follow up with reference patrons that experience im connection issues and provide research assistance via email. evaluation of openfire as an internal communication tool while the adoption of im as internal communication tool was highly encouraged, its use was not mandatory for all library personnel. based on the varied technical background of our staff and librarians, we recognized that some might find im difficult to integrate within their workflow or communication style and chose a soft-launch for our network. information technology and libraries | september 2012 16 in summer 2011, we conducted a survey of csusm library personnel (44 respondents, 99 percent of total staff) to evaluate im as an internal communication tool. (see appendix a for survey questions.) we found that 59 percent of staff use the internal im network while 85 percent use some type of im for web-based chat for work. of those who use internal im, 30 percent used it daily. while the survey was anonymous, anecdotal discussions indicate adoption rates are higher among library units where the work is technically oriented or instructional in nature, such as library systems and the information literacy program/reference. among the respondents who use im, 45 percent of library staff indicated they use it because it allows quick communication between those in the library and 39 percent like its informal nature of communication. twenty percent of total respondents preferred im to email and phone communications. two respondents use the internal im network but were dissatisfied with it and indicated it did not work well while one found it too difficult to use. an additional survey question was geared for staff members who do not use the internal im network at all (“why do you not use the library im network?”). this question was designed to find areas of possible improvement within our system to encourage greater use. survey respondents were allowed to select more than one reason. the most common reasons given by those who do not use the library im network were that they don’t feel the need (34 percent of nonusers), they mainly communicate with staff members who are also not utilizing the im network (18 percent), im does not work for their communication style (14 percent), and privacy concerns (14 percent). we believe more in-depth analysis is necessary to learn more regarding the perceived usefulness of im within our organization and to further its adoption. conclusion through additional training and user education, we hope to promote greater use of the openfire internal im network among those who work in the library. while 100 percent adoption of im as a communication tool is not a stated goal of our project, we believe that some staff have not realized the full potential of im for collaboration and productivity due to a lack of experience with this technology. in hindsight, additional training sessions beyond the initial introductory workshop to set up the spark im client may have increased the usage of im by staff. for example, providing more information on the library’s policies regarding internal im tracking and the configuration of our system may have alleviated concerns regarding privacy. in addition, we need to lead more discussions on the benefits of im for collaboration, lowering disruptions, and increasing effectiveness in the workplace. openfire and fastpath for chat reference has brought many new features that were previously unavailable to chat reference at csusm. the addition of queues, message transfer, and transcripts has enhanced the effectiveness of this service and eased its management. compared to the prior chat reference implementations that used questionpoint and meebo, this new system is more user friendly and robust. extending im beyond the reference desk | chan, ly, and meulemans 17 furthermore, the internal im network and its connection to web-based chat widgets offer the opportunity for building a library that is more open to users. library users could feasibly contact any library staff member, not just reference librarians, via im for help. we are testing this concept with a pilot project involving the csusm media library. they are staffing their own chat workgroup and a chat widget is now available on their website. in the future, we also hope to employ a chat widget for circulation and ill services, another public services area that frequently works with library users. it is important to note that the success of openfire and im in the library attracted the attention of other csusm instructional and student support areas. in spring 2011, instructional and information technology services (iits), which provides campus-wide technology services for faculty, staff, and students piloted an openfire-based im helpdesk service to assist users with technology questions and problems. as of fall 2011, the “ask an it technician” service is fully implemented and available on all campus webpages. discussions on the adoption of im for other campus student services, such as financial aid and counseling, have also occurred. in addition to being a contact point for students, im has potential to improve the internal communication within the organization. references 1. hee-kyung cho, matthias trier, and eunhee

 technology  and  libraries  |  june  2015             92   abstract   librarians  have  had  innovative  ideas  for  ways  to  use  subject  and  classification  data  to  provide  an   improved  online  search  experience  for  decades,  yet  after  thirty-­‐plus  years  of  improvements  in  our   online  catalogs,  users  continue  to  struggle  with  narrowing  down  their  subject  searches  to  provide   manageable  lists  containing  only  relevant  results.  this  article  reports  on  one  attempt  to  rectify  that   situation  by  radically  reenvisioning  the  library  catalog  interface,  enabling  users  to  interact  with  and   explore  their  search  results  in  a  profoundly  different  way.  this  new  interface  gives  users  the  option  of   viewing  a  graphical  overview  of  their  results,  grouped  by  discipline  and  subject.  results  are  depicted   as  a  two-­‐level  treemap,  which  gives  users  a  visual  representation  of  the  disciplinary  perspectives  (as   represented  by  the  main  classes  of  the  library  of  congress  classification)  and  topics  (as  represented   by  elements  of  the  library  of  congress  subject  headings)  included  in  the  results.   introduction   reading  library  literature  from  the  early  days  of  the  opac  era  is  simultaneously  inspiring  and   depressing.  the  enthusiasm  that  some  librarians  felt  in  those  days  about  the  new  possibilities  that   were  being  opened  by  online  catalogs  is  infectious.  elaine  svenonius  envisioned  a  catalog  that   could  interactively  guide  users  from  a  broad  single-­‐word  search  to  the  specific  topic  in  which  they   were  really  interested.1  pauline  cochrane  conceived  of  a  catalog  that  could  group  results  on   similar  aspects  of  a  given  subject,  showing  the  user  a  “systematic  outline”  of  what  was  available  on   the  subject  and  allowing  the  user  to  narrow  their  search  easily.2  marcia  bates  even  pondered   whether  “any  indexing/access  apparatus  that  does  not  stimulate,  intrigue,  and  give  pleasure  in  the   hunt  is  defective,”  since  “people  enjoy  exploring  knowledge,  particularly  if  they  can  pursue  mental   associations  in  the  same  way  they  do  in  their  minds.  .  .  .  should  that  not  also  carry  over  into   enjoying  exploring  an  apparatus  that  reflects  knowledge,  that  suggests  paths  not  thought  of,  and   that  shows  relationships  between  topics  that  are  surprising?”3  however,  looking  back  thirty  years   later,  it  is  dispiriting  to  consider  how  many  of  these  visions  have  not  yet  been  realized.     the  following  article  reports  on  one  attempt  to  rectify  that  situation  by  radically  reenvisioning  the   library  catalog  interface,  enabling  users  to  interact  with  and  explore  their  search  results  in  a     profoundly  different  way.  the  idea  is  to  give  users  the  option  of  viewing  a  graphical  overview  of   their  results,  grouped  by  discipline  and  subject.  this  was  achieved  by

 report  on  the  results  of  usability  testing  of  the  visual  interface  with  faculty,  academic  staff,  and   undergraduate  students.     information  technology  and  libraries  |  june  2015     94   literature  review   exploratory  subject  searching  in  library  catalogs   since  charles  ammi  cutter  published  his  rules  for  a  printed  dictionary  catalogue  in  1876,  most   library  catalogs  have  been  premised  on  the  idea  that  users  have  a  very  good  idea  of  what  they  are   looking  for  before  they  begin  to  interact  with  the  catalog.4  in  this  classic  view,  users  are  either   conducting  known-­‐item  searches—they  know  the  titles  or  the  author  of  the  books  they  want  to   find—or  they  know  the  exact  subject  on  which  they  are  interested  in  finding  books.  yet  research   has  shown  that  known-­‐item  searches  are  only  about  half  of  catalog  searches,5  and  that  users  often   have  a  very  difficult  time  expressing  their  information  needs  with  enough  detail  to  construct  a   specific  subject  search.  instead,  much  of  the  time,  users  approach  the  catalog  with  only  a  vaguely   formulated  information  need  and  an  even  vaguer  sense  of  what  words  to  type  into  the  catalog  to   get  the  resources  that  would  solve  their  information  need.6   even  in  the  earliest  days  of  the  opac  era,  librarians  were  aware  of  this  problem.  some  of  them,   including  elaine  svenonius  and  pauline  cochrane,  speculated  about  better  use  of  subject  and   classification  data  to  try  to  help  users  who  enter  too-­‐short,  overly  broad  searches  focus  their   results  on  the  information  that  they  truly  want.  one  of  cochrane’s  many  ideas  on  this  topic  was  to   use  subject  and  classification  data  “to  present  a  systematic  outline  of  a  subject,”  which  would  let   users  see  all  of  the  different  aspects  of  that  subject,  as  reflected  in  the  library’s  classification   system  and  subject  headings,  and  the  various  locations  where  those  materials  could  be  found  in   the  library.7  svenonius  suggested  using  library  classifications  to  help  narrow  users’  searches  to   appropriate  areas  of  the  catalog.  for  example,  she  suggests,  if  a  user  enters  “freedom”  as  a  search   term,  the  system  might  be  programmed  to  present  to  the  user  contexts  in  which  “freedom”  is  used   in  the  dewey  decimal  classification,  such  as  “freedom  of  choice”  or  “freedom  of  the  press.”  once   the  user  selects  a  one  of  these  phrases,  svenonius  continued,  the  system  could  present  the  user   with  additional  contextual  information,  again  allow  the  user  to  specify  which  context  is  desired,   and  then  guide  the  user  to  the  exact  call  number  range  for  information  on  the  topic.  she  concluded,   “thus  by  contextualizing  vague  words,  such  as  freedom,  within  perspective  hierarchies,  the   computer  might  guide  a  user  from  an  ineptly  or  imprecisely  articulated  search  request  to  one  that   is  quite  specific.”8   ideas  such  as  these  had  little  impact  on  the  design  of  production  library  catalogs  until  the  late   1990s,  when  a  dutch  company,  medialab  solutions,  began  developing  aquabrowser,  which   features  a  word  cloud  composed  of  synonyms  and  other  words  related  to  the  search  term  and   allows  users  to  refocus  their  search  by  clicking  on  these  words.9  aquabrowser  became  available  in   the  united  states  in  the  mid-­‐2000s,  shortly  before  north  carolina  state  university  launched  its   endeca-­‐based  catalog  in  2006.10     while  aquabrowser’s  word  cloud  is  certainly  visually  striking,  the  feature  that  these  and  most  of   the  subsequent  “next-­‐generation”  library  catalogs  implement  that  has  had  the  most  impact  on   search  behavior  is  faceting.  facets,  while  not  as  sophisticated  as  the  systems  envisioned  by     exploratory  subject  searching  in  library  catalogs:  reclaiming  the  vision  |  bauder  and  lange   doi:  10.6017/ital.v34i2.5888   95   svenonius  and  cochrane,  are  partial  solutions  to  the  problems  they  lay  out.  facets  can  serve  to   give  users  a  high-­‐level  overview  of  what  is  available  on  a  topic,  based  on  classification,  format,   period,  or  other  factors.  they  can  also  help  guide  a  user  from  an  impossibly  broad  search  to  a   more  focused  one.  various  studies  have  shown  that  faceted  interfaces  are  effective  at  helping   users  narrow  their  searches,  as  well  as  helping  them  discover  more  relevant  materials  than  they   did  when  performing  similar  tasks  on  nonfaceted  interfaces.11  however,  studies  have  also  shown   that  users  can  become  overwhelmed  by  the  number  and  variety  of  facets  available  and  the  number   of  options  shown  under  each  facet.12   visual  interfaces  to  document  corpora   when  librarians  were  pondering  how  to  create  a  better  online  library  catalog,  computer  scientists   were  investigating  the  broader  problem  of  helping  users  to  navigate  and  search  large  databases   and  collections  of  documents  effectively.  visual  interfaces  have  been  one  of  the  methods  computer   scientists  have  investigated  for  providing  user-­‐friendly  navigation,  with  perhaps  the  most   prominent  early  advocate  for  visual  interfaces  being  ben  shneiderman.13  in  recent  years,   shneiderman  and  other  researchers  have  built  and  tested  various  types  of  experimental  visual   interfaces  for  different  forms  of  information-­‐seeking.14  however,  with  a  few  exceptions,  most  of   these  visual  interfaces  have  remained  in  a  laboratory  rather  than  a  production  setting.15  with  the   exception  of  the  “date  slider,”  a  common  interface  feature  that  displays  a  bar  graph  showing  dates   related  to  the  search  results  and  allows  users  to  slide  handles  to  include  or  exclude  times  from   their  search  results,  few  current  document  search  systems  present  users  with  any  kind  of  visual   interface.   method   the  grinnell  college  libraries  use  vufind,  open-­‐source  software  originally  developed  at  villanova   university  as  a  discovery  layer  to  use  over  a  traditional  ils.  vufind  in  turn  makes  use  of  apache   solr,  a  powerful  open-­‐source  indexing  and  search  platform,  and  solrmarc,  code  developed  within   the  library  community  that  facilitates  indexing  marc  records  into  solr.  using  solrmarc,  marc   fields  and  subfields  are  mapped  to  various  fields  in  the  solr  index;  for  example,  the  contents  of   marc  field  020,  subfield  a,  and  field  773,  subfield  z,  are  both  mapped  to  a  solr  index  field  called   “isbn.”  more  than  fifty  solr  fields  are  populated  in  our  index.  our  visualization  system  was  built  on   top  of  vufind’s  solr  index  and  visualizes  data  taken  directly  from  the  index.     the  visualizations  are  created  in  javascript  using  the  d3.js  visualization  library,  and  they  are   designed  to  implement  shneiderman’s  visual  information  seeking  mantra:  “overview  first,  zoom   and  filter,  then  details-­‐on-­‐demand.”16  the  goal  was  to  give  users  the  option  of  viewing  a  graphical   overview  of  their  results,  grouped  by  disciplinary  perspective  and  topic,  and  then  allow  them  to   zoom  in  on  the  results  from  specific  perspectives  or  on  specific  topics.  once  they  have  used  the   interactive  visualization  to  narrow  their  search,  they  can  choose  to  see  a  traditional  list  of  results   with  full  bibliographic  details  about  the  items.  this  would,  ideally,  provide  a  version  of  the     information  technology  and  libraries  |  june  2015     96   systematic  outline  that  cochrane  envisioned.  it  should  also  support  users  as  they  attempt  to   narrow  down  their  search  results  and  focus  on  a  specific  aspect  of  their  chosen  subject  without   overwhelming  them  with  long  lists  of  results  or  of  facets.   currently,  we  are  visualizing  values  of  two  fields,  one  containing  the  first  letter  of  the  items’   library  of  congress  classification  (lcc)  numbers  and  the  other  containing  elements  of  the  items’   library  of  congress  subject  headings  (lcsh).  this  data  is  visualized  as  a  two-­‐level  treemap.17   first,  large  boxes  are  drawn  representing  the  number  of  items  matching  the  search  within  each   letter  of  the  lcc.  within  the  largest  of  these  boxes,  smaller  boxes  are  drawn  showing  the  most   common  elements  of  the  subject  headings  for  items  matching  that  search  within  that  lcc  main   class.  less  common  subject  heading  elements  are  combined  into  an  additional  small  box,  labeled   “x  more  topics”;  clicking  on  that  box  zooms  in  so  that  users  only  see  results  from  one  lcc  main   class,  and  it  displays  all  of  the  lcsh  headings  applied  to  items  in  that  group.  similarly,  users  can   click  on  any  of  the  smaller  lcc  boxes,  which  do  not  contain  lcsh  boxes  in  the  original   visualization,  to  zoom  in  on  that  lcc  main  class  and  see  the  lcsh  subject  headings  for  it.  both  the   large  and  the  small  boxes  are  sized  to  represent  what  proportion  of  the  results  were  in  that  lcc   main  class  or  had  that  lcsh  subject  heading.     this  is  easier  to  explain  with  a  concrete  example.  let’s  say  a  student  were  to  search  for  “climate   change”  and  click  on  the  option  to  visualize  the  results.  you  can  see  what  this  looks  like  in  figure  1.   instead  of  seeing  a  list  of  nearly  two  thousand  books,  the  student  now  sees  a  visual  representation   of  the  disciplinary  perspectives  (as  represented  by  the  main  classes  of  the  lcc)  and  topics  (as   represented  by  elements  of  the  lcsh)  included  in  the  results.  users  could  click  to  zoom  in  on  any   main  class  within  the  lcc  to  see  all  of  the  topics  covered  by  books  in  that  class,  as  in  figure  2,   where  the  student  has  zoomed  in  on  “s  –  agriculture.”  or  users  could  click  on  any  topic  facet  to  see   a  traditional  results  list  of  books  with  that  topic  facet  in  that  main  class.  at  any  zoom  level,  users   could  choose  to  return  to  the  traditional  results  list  by  clicking  on  the  “list  results”  option.18   we  launched  this  feature  in  our  catalog  midway  through  the  spring  2014  semester.  formal   usability  testing  was  completed  with  five  advanced  undergraduates,  three  staff,  and  two  faculty   members  in  the  summer  of  2014.  (see  appendix  a  for  the  outline  of  the  usability  test.)  one  first-­‐ year  student  completed  usability  testing  in  the  fall  2014  semester.  the  usability  study  asked   participants  to  complete  a  set  list  of  nine  specific,  predetermined  tasks.  some  tasks  involved  the   use  of  now-­‐standard  catalog  features,  such  as  saving  results  to  a  list  and  emailing  results  to  oneself,   while  about  half  of  the  tasks  involved  navigation  of  the  visualization  tool,  which  was  entirely  new   to  the  participants.  each  participant  received  the  same  tasks  and  testing  experience  regardless  of   their  status  as  a  student,  faculty,  or  staff,  and  each  academic  division  was  represented  among  the   participants.       exploratory  subject  searching  in  library  catalogs:  reclaiming  the  vision  |  bauder  and  lange   doi:  10.6017/ital.v34i2.5888   97     figure  2.  visualization  of  the  results  for  a  search  for  “climate  change,”  filtered  to  show  only   results  with  library  of  congress  classification  numbers  starting  with  s.   results   usability  testing  revealed  no  major  obstacles  in  the  way  of  users’  ability  to  navigate  the   visualization  feature;  the  visualized  search  results  were  quickly  deciphered  by  the  participants   with  the  assistance  of  the  context  set  by  the  study’s  outlined  tasks.  familiarity  with  library   catalogs  in  general,  and  the  grinnell  college  libraries  catalog  in  particular,  showed  no  marked   impact  on  users’  performance.  no  particular  user  group  performed  as  an  outlier  in  regards  to   users’  general  ability  to  complete  tasks  or  the  time  required  to  do  so.     the  most  common  issue  to  arise  during  the  session  concerned  the  visualization’s  truncated  text,   which  appears  in  the  far  left  column  of  results  when  the  descriptor  text  contains  too  many   characters  for  the  space  allocated.  (an  example  of  this  truncated  text  can  be  seen  in  figure  1.)  the     information  technology  and  libraries  |  june  2015     98   subject  boxes  appearing  in  the  furthest  left  column  contain  the  least  results,  and  therefore  receive   the  least  space  within  the  visualization.  this  limited  space  sometimes  results  in  truncated  text.   the  full-­‐text  can  be  viewed  by  hovering  over  the  truncated  text  box,  but  few  users  discovered  this   capability.  another  common  concern  involved  a  participant’s  ability  to  switch  their  search  results   from  the  default  list  view  to  the  visualized  view.  all  participants  were  capable  of  selecting  the   “visualize  these  results”  button  required  to  produce  the  visualization,  but  a  handful  of   participants  expressed  that  they  feared  they  would  not  find  that  option  if  they  were  not  prompted   to  do  so.   participants  remarked  that  the  visualization  initially  appeared  daunting  but  then  quickly  became   comfortable  navigating  the  results.  most  participants,  including  staff,  stated  that  they  found  the   tool  useful  and  intended  to  use  it  in  the  future  during  the  course  of  their  typical  work  at  the  college.   conclusion   librarians  have  had  innovative  ideas  for  ways  to  use  subject  and  classification  data  to  provide  an   improved  online  search  experience  for  decades,  yet  after  thirty-­‐plus  years  of  improvements  in   online  catalogs,  users  continue  to  struggle  with  narrowing  down  their  searches  to  produce   manageable  lists  containing  only  relevant  results.19  computer  scientists  have  been  advocating  for   interfaces  to  support  visual  information-­‐seeking  since  the  1980s.  finally,  hardware  and  software   have  improved  to  the  point  where  many  of  these  ideas  can  be  implemented  feasibly,  even  by   relatively  small  libraries.  now  is  the  time  to  put  some  of  them  into  production  and  see  how  well   they  work  for  library  users.  the  particular  visualizations  reported  in  this  article  may  or  may  not   be  the  best  possible  visualizations  of  bibliographic  data,  but  we  will  never  know  which  of  these   ideas  might  prove  to  be  the  revolution  that  library  discovery  interfaces  need  until  we  try  them.         exploratory  subject  searching  in  library  catalogs:  reclaiming

 you  just  a  few  quick  questions.   —have  you  searched  for  materials  using  the  grinnell  college  libraries’  website  before?  if  so,  what   for  and  when?  (for  students  only:  could  you  please  estimate  how  many  research  projects  you’ve   done  at  grinnell  college  using  the  library  catalog?)   in  the  grinnell  college  libraries,  we’re  testing  out  a  new  tool  in  our  catalog  that  presents  search   results  in  a  different  way  than  you  are  used  to.  now  i’m  going  to  read  you  a  short  explanation  of   why  we  created  this  tool  and  what  we  hope  the  tool  will  do  for  you  before  we  start  the  test.   research  is  a  conversation:  a  scholar  reads  writings  by  other  scholars  in  the  field,  then  enters  into   dialogue  with  them  in  his  or  her  own  writing.  most  of  the  time,  these  conversations  happen  within   the  boundaries  of  a  single  discipline,  such  as  chemistry,  sociology,  or  art  history,  even  when  many   disciplines  are  discussing  similar  topics.  but  when  you  do  a  search  in  a  library  catalog,  writings   that  are  part  of  many  different  conversations  are  all  jumbled  together  in  the  results.  it’s  like  being   thrown  into  one  big  room  where  all  of  these  scholars,  from  all  of  these  different  disciplines,  are   talking  over  each  other  all  at  once.  our  new  visualization  tool  aims  to  help  you  sort  all  of  these   writings  into  the  separate  conversations  in  which  they  originated.     scenarios   now  i  am  going  to  ask  you  to  try  doing  some  specific  tasks  using  3search.  you  should  read  the   instructions  aloud  for  all  tasks  individually  prior  to  beginning  each.  and  again,  as  much  as  possible,   it  will  help  us  if  you  can  try  to  think  out  loud  as  you  go  along.     please  begin  by  reading  the  first  scenario  aloud  and  then  begin  the  first  scenario.  if  you  are  unsure   whether  you  finished  the  task  or  not,  please  ask  me.  i  can  confirm  if  the  task  has  been  completed.   once  you  are  done  with  scenario  1,  please  continue  onto  scenario  2  by  reading  it  aloud  and  then   beginning  the  task.  continue  this  process  until  all  scenarios  are  finished.  if  you  cannot  complete  a   task,  please  be  honest  and  try  to  explain  briefly  why  you  were  unsuccessful  and  continue  to  the   next.     1. pretend  that  you  are  writing  a  paper  about  issues  related  to  privacy  and  the  internet.  do  a   search  in  3search  with  the  words  “privacy  internet.”   2. please  select  the  first  worldcat  result  and  attempt  to  determine  whether  you  have  access   to  the  full  text  of  this  book.  if  not,  please  indicate  where  you  could  request  the  full  text   through  the  interlibrary  loan  service.   3. go  back  to  your  initial  search  results.  please  choose  “explore  these  results”  of  the  ebsco   database  results.  choose  an  article.  if  you  have  unlimited  texting,  have  the  article’s     information  technology  and  libraries  |  june  2015     100   information  texted  to  your  cell  phone.  then,  add  the  article  to  a  new  list  for  future   reference  throughout  this  project.   4. go  back  to  your  initial  search  results.  for  grinnell  college’s  collections  results,  click  on  the   “explore  these  results”  link.  then  click  on  the  “visualize  results”  link  to  visualize  the   results.  which  disciplines  appear  to  have  the  greatest  interest  in  this  topic?   5. when  privacy  and  the  internet  are  discussed  in  the  context  of  law,  what  are  some  of  the   topics  that  are  frequently  covered  in  these  discussions?   6. one  specific  topic  you  are  considering  is  the  legal  issues  around  libel  and  slander  on  the   internet.  how  many  resources  do  the  libraries  have  on  that  specific  topic?   7. click  on  “q  –  science,”  to  see  the  results  authored  by  theoretical  computer  scientists.  based   on  these  results,  what  are  some  of  the  topics  that  are  frequently  covered  in  their   discussions  when  these  computer  scientists  discuss  privacy  and  the  internet?   8. pretend  that  you  are  writing  this  paper  for  a  computer  science  class  and  you  are  supposed   to  address  your  topic  from  a  computer  science  perspective.  please  narrow  your  results  to   only  show  results  that  are  in  the  format  of  a  book.  based  on  this  new  visualization,  what   might  be  some  good  topics  to  consider?   9. add  one  of  these  books  to  the  list  you  created  in  step  3.  please  email  all  of  the  items  on  this   list  to  yourself.   debriefing   thank  you.  that  is  it  for  the  computer  tasks.  i  have  a  few  quick  questions  for  you  now  that  you   have  gotten  a  chance  to  use  the  site.   1. what  do  you  think  about  3search?  is  it  something  that  you  would  use?  why  or  why  not?   2. what  is  your  favorite  thing  about  3search?   3. what  is  your  least  favorite  thing  about  3search?   4. did  you  find  the  visualization  function  useful?  why  or  why  not?   5. do  you  have  any  recommendations  for  changes  to  the  way  this  site  looks  or  works?         exploratory  subject  searching  in  library  catalogs:  reclaiming  the  vision  |

sheringal. © 2022. abstract library and information science has been at an infant stage in pakistan, primarily in resource management, description, discovery, and access. the reasons are many, including the lack of interest and use of modern tools, techniques, and best practices by librarians in pakistan. finding a solution to these challenges requires a comprehensive study that identifies the current state of libraries in pakistan. this paper fills this gap in the literature by reviewing the relevant literature published between 2015 and 2021 and selected through a rigorous search and selection methodology. it also analyzes the websites of 82 libraries in pakistan through a theoretical framework based on various aspects. the findings of this study include: libraries in pakistan need a transition from traditional and limited solutions to more advanced information and communication technology (ict)-enabled, user-friendly, and state-of-the-art systems to produce dynamic, consumable, and sharable knowledge space. they must adopt social semantic cataloging to bring all the stakeholders on a single platform. a libraries consortium should be developed to link users to local, multilingual, and multicultural collections for improved knowledge production, recording, sharing, acquisition, and dissemination. these findings benefit pakistani libraries, librarians, information science professionals, and researchers in other developing countries. to the best of our knowledge, this is the first study of its kind providing insights into the current state of libraries in pakistan through the study of their websites using a rigorous theoretical framework and in the light of the latest relevant literature. introduction with the inception of the web, library and information science (lis) professionals and researchers have solved several major challenges and issues regarding resource description, discovery, and access. yet, many new problems arise in the practices and services delivered by libraries if they are not in line with emerging technologies and standards. these problems are promptly addressed by the libraries and their lis professionals using cutting-edge technologies, sufficient training, and the availability of the required resources. this practice keeps these libraries functional and acceptable among their users, especially in developed countries. on the other hand, in less developed and developing countries, libraries are losing their importance, which may be due to the adherence of these libraries to outdated lis approaches. pakistan is one of the developing countries where this is often observed. but, before devising a solution to regain their value, importance, and acceptance, it is essential to identify the current state of libraries in pakistan. to address this need, this paper reviews and summarizes the findings of the well-reputed published literature regarding libraries in pakistan and collects and analyzes

chang, who analyzed lis practices by reviewing relevant literature regarding libraries in korea from 1970 to 2018.2 however, to the best of our knowledge, we found no holistic, systematic literature review covering the current state of library management practices in pakistan and highlighting its key challenges, issues, and research opportunities. similarly, ganaee and rafiq studied the current state and features of the websites of the 85 academic libraries of pakistan via surveys and interviews to identify their issues and problems.3 the websites were analyzed for contrasting color schemes, readable text, minimal use of horizontal scrolling, language, staff details, opacs, navigation, and other details of the information architecture. inspired by ganaee and rafiq, this study contributes a theoretical evaluation framework to study the current state of libraries by analyzing their websites. it comprises several aspects and criteria, including the availability of general information and information about resources and collections, the use of web 2.0 tools, the design of the website, the offering of web-based services, the use of instruction tools, and the application of accessibility guidelines for supporting individuals with visual and other impairments. the paper extends the findings and implications of the aforementioned research by highlighting the current state of library management practices in the libraries of pakistan, the challenges and issues those libraries face, and the research opportunities that lie ahead of them in the realm of modern digital technologies. the paper provides a systematic literature review of the relevant literature on the libraries of pakistan and devises a theoretical framework to collect and analyze data by visiting the websites of the selected 82 libraries of pakistan that have an online presence.4 the study has implications for researchers and lis professionals in pakistan and those of developing countries coping with similar challenges and issues. the first section of this paper presents the methodology for selecting relevant literature by adopting the well-known prisma framework.5 the second section presents a summary of key findings. the third section presents a discussion and analysis. the last section concludes the paper, followed by endnotes and an appendix holding data about the selected 82 websites of the libraries of pakistan. methodology this section discusses the literature search and selection strategy and the theoretical evaluation framework used to study the websites of the selected 82 libraries of pakistan. the literature search and selection strategy this section discusses the search and selection process for collecting the relevant literature using google scholar. google scholar indexes more than 389 million records and has the highest coverage of knowledge and research areas.6 we developed rigorous search and selection criteria by adopting the prisma methodology for gathering the relevant scholarly literature. 7 the prisma methodology is a systematic literature review approach, ensuring transparent and complete reporting on selecting relevant literature in a given course of inquiry.8 it tracks a full record of how the relevant literature was selected. it visualizes the details in a prisma flow diagram,9 shown in figure 1. the first step in applying prisma and following this diagram is to develop a search framework consisting of keywords or search queries that maximize the coverage and accuracy of finding relevant studies. the search framework for this study was developed by following ullah and khusro and liberati et al.10 table 1 summarizes the search framework and provides details on the search query and the number of total records matched by reading the information technology and libraries september 2022 library management practices in the libraries of pakistan 3 ullah, khusro, and ullah search results list’s title and text snippet, which resulted in the number of relevant records reported in the third column. the duplicates that appear after entering the next search query are recorded in the fourth column. the duplicates are removed from the counting of relevant records matched against the given search query. the net results are reported in the final column to be further screened by title, abstract, and other details on the publisher’s website. the inclusion/exclusion criteria are required to narrow down the selection criteria further so that only relevant items are included, and the irrelevant ones are filtered out or excluded. using this search framework, our inclusion criteria selected the following publications: • publications that discuss computer and web-based software solutions regarding resource acquisition, description (cataloging), discovery, and access inside the library or libraries of pakistan. • publications that highlight the use and the adaptation of technologies, especially modern cataloging practices, the use of semantic web, and linked open data (lod) in the libraries of pakistan. • publications that highlight issues and challenges faced by pakistani libraries to become part of the global library community and learn from their best practices in terms of software and related technologies. • publications in the english language with pakistani context and published during 2015 – 2021. the exclusion criteria to remove items from the list included the following: • publications published before 2015 and written in languages other than english. • publications that are of low academic significance with low-quality publication venues. examples include papers having incomplete details or those published in non-peerreviewed journals and conferences. • theses, dissertations, surveys, review articles, patents, and citations. information technology and libraries september 2022 library management practices in the libraries of pakistan 4 ullah, khusro, and ullah table 1. the

and removed, leading to 2,874 records left for initial screening. after an initial screening using title and text snippets, we identified 110 records to be relevant, leaving a total of 2,764 records. these 110 records were then accessed by visiting their publisher’s websites to read their title, abstract, and other details. the full texts of these papers were obtained. after applying skimming on the full -text of these records and considering the inclusion/exclusion criteria, 26 were excluded leaving behind 84 publications for in-depth reading and analysis. an in-depth reading of these 84 articles and application of the inclusion/exclusion criteria identified a further 3 articles to be irrelevant, leaving behind 81 articles to be relevant and to be included in the analysis and

key observations the lis practices in pakistan’s libraries are gradually shifting from manual to digital. however, they are still far from meeting the latest international practices of resource management, acquisition, cataloging, classification, circulation, discovery, access, and accessibility for people with disabilities, including those with visual impairments. this section has a twofold objective. first, it reviews the latest literature regarding the current state of lis practices in the libraries of pakistan to identify challenges and issues being faced and future research opportunities. second, it information technology and libraries september 2022 library management practices in the libraries of pakistan 9 ullah, khusro, and ullah extends these findings by evaluating the websites of the selected 82 libraries for a clearer picture of the current state of these chosen libraries. lis practices in the light of published literature this section discusses lis practices in the libraries of pakistan with details from the published literature. the following subsections briefly discuss these practices. collection development and management books are given greater importance as the main holdings in the libraries of pakistan. currently, printed books are selected in the conventional manual manner. book selection tools include suppliers’ lists, publishers’ catalogs, book fairs/visits to book shops, book reviews, recommendations from the readers, selection committees, suggestion registers, and publishers/suppliers’ desk copies. the requested books are supplied to the libraries. librarians check these books physically and verify their accuracy. if a book is damaged or not present, it is reported to the vendor so that new copies could be arranged. there is a rare case of online or electronic book selection and procurement from national and international book vendors. there is also a very rare practice of purchasing softcover books in batches. these aspects have been discussed in several research publications by lis professionals and researchers of pakistan. one prominent reason is the lack of a sufficient budget and standard clear resource acquisition and management policy.19 the following are some of the notable challenges and issues that appeared in the published literature: • the development of the quality collection.20 • lack of formal policies and guidelines for collection selection, acquisition, and related activities.21 • lack of electronic resources22 and challenges in their subscription and off-campus access. 23 • inadequate collections and the resulting limited use of resources.24 • financial constraints.25 • lack of formal policies and procedures for collection development and management, including selection, acquisition, digitization, and access.26 • lack of proper library communities and the coordination among them for collection development and management.27 • failure to fulfill the user information needs.28 researchers have made some recommendations (that could also be treated as research opportunities) to address these challenges: the libraries need to meet user needs and maintain their pace for disseminating the current and updated scientific knowledge and new insights in the literature to achieve excellence in service delivery.29 the factors affecting lis practices in the academic libraries of pakistan include collection development goals, management policies , and procedures, user requirements, budget, and evaluation.30 the user information needs should be considered to the fullest, and a user-centric approach should be developed to improve content selection.31 librarians should understand the use of linked and open data (lod) for creating standard metadata records for information resources management in libraries. 32 in this regard, the librarians should consider the major challenges, including the lack of technical expertise, awareness of the latest tools and technologies, the complexity of technologies, non-availability of vocabularies, and legal issues.33 the librarians must consider the research community’s limited information technology and libraries september 2022 library management practices in the libraries of pakistan 10 ullah, khusro, and ullah demand and use of e-resources in academic activities.34 there is a significant relationship between the digital resources database and the development of academic research for generating innovative ideas and improving researchers’ cognitive abilities. 35 therefore, libraries must be well aware of maintaining sufficient and up-to-date resources. social networking sites should be considered for knowledge management practices among the employees in public and private universities.36 effective policies should be developed to increase the researchers’ satisfaction and research productivity.37 resource description, discovery, and access as it relates to resource description and access, most libraries in pakistan use online public access catalogs (opacs). the use of specialized software, including, e.g., dspace and e-prints, for developing and using institutional repositories and digital libraries is rare. libraries are still relying on the conventional manual, partially computerized, slow, and old methods of records management and are limited to opacs-based search and retrieval. they are less aware and familiar with the modern best practices of using lod for resource description, sharing, and access. it is unproven and new to the libraries of pakistan for several reasons, including the complexity in deployment and usage and the constraints on financial and human resources.38 some of the notable challenges and issues that appeared in the published literature include the following: • lack of or limited searching and access to resources39 and their sharing. 40 • lack of synchronous or digital reference services41 and the poor availability of virtual reference services.42 • lack of search and retrieval solution for multilingual resources written in pashtu, arabic, and urdu.43 • limited or no use of big data analytics to improve acquisition, preservation, curation, and data analysis.44 • insufficient information on the websites regarding their libraries and lack of communication support for end users.45 • less frequent use of web 2.0, website aid tools, and limited information about their libraries.46 • the smaller size of the library website and the lack of aids including site index, frequently asked questions, user guides about its use.47 • the lack of awareness, best practices, it staff, and the complexity in implementing lod in resource description, discovery, sharing, and access.48 these challenges can be addressed if the recommendations of the researchers are considered. some of these recommendations, which also serve as research opportunities, include: the library management practices should consider using and exploiting ontologies and lod to develop more rigorous classification systems for improved resource description, discovery, and access.49 strategic planning and policies are essential for incorporating ict in the libraries of pakistan, with emphasis on resource description, discovery, access, and sharing through web-based services.50 besides the library’s reference desk and e-mail service, the online instant messaging and search engines tools must be used for virtual reference service (vrs) in libraries. a proper set of written policies and standard operating procedures (sops) for vrs must be introduced.51 the collaboration and sharing of experiences and skills for deploying lod is also vital.52 through lod, the libraries of pakistan can be linked to other global libraries to promote our indigenous information technology and libraries september 2022 library management practices in the libraries of pakistan 11 ullah, khusro, and ullah literature on the web.53 it is challenging to migrate data from text-based and marc catalogs to linked data formats. in addition, the recognition and providence of the uris are challenging. synchronizing terminologies with linked data technology and minimizing its complexity is also challenging. the conversion of marc 21 records to resource description framework (rdf) is onerous.54 a list of the bibliographic databases should be provided on the library website with instructions for their usage and relevant content should be made accessible discipline-wise through proper authentication login.55 services like “ask a librarian,” search, searching via barcode scanners, and maintaining a rich database should be considered by each library through their online and mobile phone interfaces.56 in developing smartphone-based library applications, it is essential to consider service quality, affinity, usefulness, ease of use, satisfaction, confirmation, and continuous usage.57 the information architecture of libraries’ websites should be analyzed from the perspective of their users, and their navigation system should be improved and adapted accordingly.58 the usefulness and cost are the most influential factors that should be considered while adopting library software such as koha.59 the design and quality of the contents and services of the library website are important.60 the use of digital library resources positively impacts research productivity and should be considered. 61 adherence to new standards, practices, and technologies the lack of interest from library staff in adopting and adhering to new standards and technologies is another inevitable aspect. another reason for this non-adherence could be the lack of knowledge by upper management and failure to understand the modern-day needs of library users. however, some developments are taking momentum. for example, several libraries offer web-based services.62 in some scenarios, university students use the social web to access and share resources.63 the pakistan scientific and technological information center (pastic) is developing a searchable database of indigenous collections64 supporting smartphone-based search and access.65 pastic is also creating a consortium-level public access catalog of the scientific periodicals produced by the authors of pakistan.66 the agha khan university has developed an integrated resource management system for connecting different, geographically dispersed libraries of various campuses in pakistan.67 access to digital libraries through the higher education of pakistan (hec) digital library, a library management system, and e-document delivery are some of the notable innovations in the lis domain of pakistan. 68 there are 122 public universities, 95 private universities, and more than 600 non-degree-awarding institutions with hec-dl access.69 the lis practices in pakistani libraries mostly suffer from the lack of professional training,70 awareness of the latest library standards and technologies,71 technological and it proficiency,72 policies for library processes and ict,73 knowledge regarding lod technologies,74 engagement with digitization activities,75 resource sharing, and collaboration,76 sufficient financial resources,77 the supportive and assistive atmosphere for persons with special needs,78 as well as issues regarding archiving, cataloging, and disseminating local and indigenous literature and artifacts.79 a library must find ways of adapting new tools, standards, technologies, and necessary training to support users in resource management, discovery, and access. the hec pakistan maintains one such library to offer free access to research publications and periodicals in different universities of pakistan and their scholars for off-campus online access.80 however, most university library users are not fully satisfied with collection development, and a major part of the literature is still not information technology and libraries september 2022 library management practices in the libraries of pakistan 12 ullah, khusro, and ullah accessible.81 besides, as discussed, pastic is playing its active role in developing a library consortium and a searchable database/catalog of the indigenous collections of pakistan. several university librarians have adopted knowledge management practices to deliver and improve their library services efficiently.82 apart from these few initiatives, the research and development of lis practices in the libraries of pakistan have been at very minimum and need significant attention. some of the notable challenges and issues that appeared in the published literature include • librarians have limited or outdated knowledge regarding research data management.83 • the inappropriate infrastructure.84 • limited or no use of ict, knowledge, and expertise in the use of computers, internet connectivity issues, inadequate computer labs.85 • training and leadership.86 • lack of supporting it staff.87 • lack or limited use of human resource management88 and leadership.89 • financial constraints.90 • lack of dynamic websites for the libraries.91 • lack of tools and standard library software.92 • the very basic level of digital competencies for developing, managing, and protecting digital libraries in universities of pakistan.93 • lack of uniformity and standard features in library websites. 94 • there is less frequent use of web 2.0, website aid tools, and limited information about their libraries.95 • the smaller size of the library website and the lack of aids including site index, frequently asked questions, user guides about its use.96 • the relative infant stage of information commons (information technology infrastructure, services, and resources).97 • negligible willingness and interest in research data management. 98 • reluctance in sharing research data99 and weak and informal collaboration on research.100 some recommendations (that could also be treated as research opportunities) made by researchers include: services, including electronic services, librarian’s end services, and technical knowledge services, should be improved in the special libraries of pakistan. 101 it is essential to understand the need to deploy and use library software, including, e.g., koha, dspace, e-prints, and evergreen.102 human resource management, especially effective leadership with a broader vision, boldness, charismatic personality, and knowledge dissemination abilities, is required to lead staff and manage their social relationships.103 as an information manager of the library, a librarian must be fully aware of web 3.0, the semantic web, and artificial intelligence (ai) tools to become expert in the digital landscape.104 web 2.0 tools and social networking sites should be used in marketing and advertising the library services to the end users.105 the cataloging paradigms should incorporate social collaborative cataloging metadata. 106 artificial intelligence tools and services should be considered where lis professionals can collaborate and join hands with computer science professionals to develop libraries.107 academic libraries’ performance can be improved by using big data tools and analytics.108 quality enhancement and industrial affiliation are important for increasing the quality and quantity of research in academia. 109 the information technology and libraries september 2022 library management practices in the libraries of pakistan 13 ullah, khusro, and ullah digital library, institutional repository software, bibliographic databases, e-journals searching, and referencing tools are very important for increasing the research production of the public sector universities.110 the competencies of ict skills, education in copyright laws and intellectual property, using digital and physical learning resources, and collection development must be improved.111 hec must provide funds for information commons projects for significant benefits to library users.112 lis practices in the light of the studied websites this section attempts to highlight the current state of the libraries in pakistan through data and observations collected from their websites. reviewing a library’s website reveals several aspects of its current state. table a-1 in appendix a summarizes the collected data obtained through the evaluation framework discussed in the methodology section and summarized in table 2. for example, a library with a website that is not user-centered and accessible to people with visual impairments, a criterion outlined as the third item in table 2, may face issues with supporting it staff, lack of expertise, and budget constraints. a library that is unable to offer web-based services cannot meet the needs of a major portion of its users interested in accessing content and servi ces online. a similar impact is connected to each of the remaining criteria of the evaluation framework. the lack of certain pieces of information on the library website affects their users negatively and may restrain them from using it. it is notable that most of the libraries of pakistan have no websites at all, which makes it challenging to discuss their strengths and limitations. as shown in figure 2, only 36% (of the selected 82 websites) of the libraries listed on the hec website have websites leaving 64% that have no online presence. this also makes it challenging to draw a clearer picture of the current state of libraries of pakistan and, therefore, the statistics presented here depict only a rough estimation of the exact details. figure 2. percentage of libraries in pakistan with and without websites. information technology and libraries september

these tools are for the new visitors or the person who requires instruction in navigation, search, and access to the contents of the library’s website. most of the libraries (67 out of 82: 81.7%) do not offer instructional tools on the websites. only a few (15 out of 82: 18. 3%) provide instructional tools in one form or the other. these include information literacy programs (10 out of 82:

reveals that the majority are not technically sound and cannot assist and offer services to its users, including people with visual or physical impairments. the key observations made in the previous section emphasize the need for the libraries of pakistan to transform their libraries’ practices from manual to automatic and webbased services. this can be achieved through collaborative research and development efforts from several domains, including computer science, lis, human-computer interaction, ai, the semantic web, and lod. there are several examples of library consortia that enable collaborative efforts to make available and accessible catalogs, websites, and activities from a single platform.113 these include the online information technology and libraries september 2022 library management practices in the libraries of pakistan 22 ullah, khusro, and ullah computer library center (oclc), the international coalition of library consortia (icolc), hathitrust digital library, the arxiv e-print archive, google books, and shared print storage.114 in pakistan, pastic made the first effort to develop such a consortium115 to allow access to the holdings of the libraries of pakistan by combining their opacs. it offers a searchable database of the collections and enables resource sharing among all the member libraries.116 however, its successful implementation in pakistan requires the willingness of data sharing, professional interaction, and benefiting from the modern technologies among all the libraries of pakistan. the consortium should be supported with the best practices from information retrieval and semantic web technologies to offer better search and retrieval functionalities. users should be made part of the resource description so that the idea of social semantic cataloging117 can be realized, where users can discuss their information needs, recommend books and resources, and enrich the catalog with user-generated content. the artificial intelligence and deep learning algorithms should be exploited in book recommendations so that the available professional metadata and user-generated content could be used to the fullest in serving the users’ information needs. the resulting rich metadata should be made available and consumable on the lod to benefit other potential applications. this will enable the libraries to meet the complex information needs of the users, who describe them in natural language. the natural language is ambiguous, and resources described through user-generated content produced by users in the same language will better support the search and recommendation of books.118 this will improve the resource description, discovery, and access services of the libraries of pakistan to a greater extent. figure 3 depicts another significant limitation of the websites of the libraries of pakistan : extremely limited availability of navigational, retrieval, and visualization aids for people with visual impairments. most of the libraries’ websites have no provision for accessibility mechanisms. this is unfortunate as in 2017 it was reported that 21.78 million people were affected by blindness and vision impairment.119 although several technological aids have been defined for performing daily life activities, including navigation, orientation, localization, obstacle detection, etc.,120 the libraries of pakistan, in the majority, lack accessibility-related solutions for those who are blind or have a visual impairment. holdings should be enriched with audio and braille books and supplemented with an ict-based accessibility solution. the library building should accommodate visitors with diverse needs. information about accessibility should be shared as part of the general information on the library’s website. in this regard, all the stakeholders of the libraries, including government and non-government organizations, educational institutions, and lis professionals, should be made involved to work collaboratively on an effective accessibility solution for all library users.121 smartphones have been among the top trends in pakistan, especially for college and university students who use them most frequently. according to the infographic by grappetite, 77% of smartphone users are between 21 and 30, and 12% are aged 31 to 40 years.122 by closely looking at these statistics, people of these two age groups are the most potential users of libraries as they usually need a variety of books. according to statista, smartphone ownership in pakistan has increased from 10% in 2014 to 51% in 2020.123 according to pakistan telecommunication authority, currently there are 191 million cellular/mobile phone subscribers, and there are 110 million 3g/4g subscribers.124 these statistics suggest that libraries should also benefit from information technology and libraries september 2022 library management practices in the libraries of pakistan 23 ullah, khusro, and ullah incorporating smartphones. the most prominent opportunities are developing smartphone apps that support users in knowing about the collection of a library via the web and producing an interactive user interface that helps them find answers to several of their questions regarding library services. the library opacs can be made usable and accessible through mobile web applications. there are several prospects and opportunities regarding using library space for people with disabilities through smartphones. a smartphone application can be developed to enable readers in navigation, localization, and finding items of interest in the library. conclusions this study aims to provide a holistic view of the current state of libraries in pakistan in the light of the most relevant and recent research works from lis professionals and researchers. it also attempts to identify some of the major challenges, issues, and research opportunities regarding the current state of lis practices in libraries of pakistan with that of technologically advanced countries. the study suggests a need for increasing technology proficiency, adaptability of the latest technologies, proper legislation for lis practices that meet international standards, improvements in collection development, and efforts to meet library users’ needs. the libraries of pakistan need a transition from traditional and limited solutions to a more advanced, ict-enabled, user-friendly, and state-of-the-art system to produce a dynamic, consumable, and sharable knowledge space. the libraries must adopt a social semantic cataloging environment to bring all stakeholders to a single platform. development of a library consortium is critical to connect our local, multilingual, and multicultural collections to users for improved knowledge production, recording, sharing, acquisition, and dissemination. we hope that lis professionals of pakistan and the rest of the world, in general, find this article supportive to their current and future studies. information technology and libraries september 2022 library management practices in the libraries of pakista 24 ullah, khusro, and ullah appendix a:

endnotes investigations into library web-scale discovery services jason vaughan information technology and libraries | march 2012 32 abstract web-scale discovery services for libraries provide deep discovery to a library’s local and licensed content and represent an evolution—perhaps a revolution—for end-user information discovery as pertains to library collections. this article frames the topic of web-scale discovery and begins by illuminating web-scale discovery from an academic library’s perspective—that is, the internal perspective seeking widespread staff participation in the discovery conversation. this included the creation of the discovery task force, a group that educated library staff, conducted internal staff surveys, and gathered observations from early adopters. the article next addresses the substantial research conducted with library vendors that have developed these services. such work included drafting of multiple comprehensive question lists distributed to the vendors, onsite vendor visits, and continual tracking of service enhancements. together, feedback gained from library staff, insights arrived at by the discovery task force, and information gathered from vendors collectively informed the recommendation of a service for the unlv libraries. introduction web-scale discovery services, combining vast repositories of content with accessible, intuitive interfaces, hold the potential to greatly facilitate the research process. while the technologies underlying such services are not new, commercial vendors releasing such services, and their work and agreements with publishers and aggregators to preindex content, is very new. this article in particular frames the topic of web-scale discovery and helps illuminate some of the concerns and commendations related to web-scale discovery from one library’s staff perspective—that is, the internal perspective. the second part focuses on detailed dialog with the commercial vendors, enabling the library to gain a better understanding of these services. in this sense, the second half is focused externally. given that web-scale discovery is new for the library environment, the author was unable to find any substantive published work detailing identification, research, evaluation, and recommendation related to library web-scale discovery services. it’s hoped that this article will serve as the ideal primer for other libraries exploring or contemplating exploration of these groundbreaking services. web-scale discovery services are able to index a variety of content, whether hosted locally or remotely. such content can include library ils records, digital collections, institutional repository content, and content from locally developed and hosted databases. such capabilities existed, to varying degrees, in next-generation library catalogs that debuted in the mid 2000s. in addition, web-scale discovery services pre–index remotely hosted content, whether purchased or licensed by the library. this latter set of content—hundreds of millions of items—can include items such as e-books, publisher or aggregator content for tens of thousands of full-text journals, content from abstracting and indexing databases, and materials housed in open-access repositories. for purposes of this article, web-scale discovery services are flexible services which jason vaughan (jason.vaughan@unlv.edu) is director, library technologies, university of nevada, las vegas. investigations into library web-scale discovery services | vaughan 33 provide quick and seamless discovery, delivery, and relevancy-ranking capabilities across a huge repository of content. commercial web-scale discovery vendors have brokered agreements with content providers (publishers and aggregators), allowing them to pre–index item metadata and full-text content (unlike the traditional federated search model). this approach lends itself to extremely rapid search and return of results ranked by relevancy, which can then be sorted in various ways according to the researcher’s whim (publication date, item type, full text only, etc.). by default, an intuitive, simple, google-like search box is provided (along with advanced search capabilities for those wishing this approach). the interface includes design cues expected by today’s researchers (such as faceted browsing) and, for libraries wishing to extend and customize the service, embraces an open architecture in comparison to traditional ils systems. why web-scale discovery? as illustrated by research dating back primarily to the 1990s, library discovery systems within the networked online environment have evolved, yet continue to struggle to serve users. as a result, the library (or systems supported and maintained by the library) is often not the first stop for research—or worse, not a stop at all. users accustomed to a quick, easy, “must have it now” environment have defected, and research continues to illustrate this fact. rather than weave these research findings into a paragraph or page, below are some illustrative quotes to convey this challenge. the quotations below were chosen because they succinctly capture findings from research involving dozens, hundreds, and in some cases thousands of participants or respondents: people do not just use information that is easy to find; they even use information that they know to be of poor quality and less reliable—so long as it requires little effort to find—rather than using information they know to be of high quality and reliable, though harder to find.1 * * * today, there are numerous alternative avenues for discovery, and libraries are challenged to determine what role they should appropriately play. basic scholarly information use practices have shifted rapidly in recent years, and as a result the academic library is increasingly being disintermediated from the discovery process, risking irrelevance in one of its core functional areas [that of the library serving as a starting point or gateway for locating research information] . . . we have seen faculty members steadily shifting towards reliance on networklevel electronic resources, and a corresponding decline in interest in using locally provided tools for discovery.2 * * * a seamless, easy flow from discovery through delivery is critical to end users. this point may seem obvious, but it is important to remember that for many end users, without the delivery of something he or she wants or needs, discovery alone is a waste of time.3 * * * end users’ expectations of data quality arise largely from their experiences of how information is organized on popular web sites. . . 4 * * * [user] expectations are increasingly driven by their experiences with search engines like google and online bookstores like amazon. when end users conduct a search in a library information technology and libraries | march 2012 34 catalog, they expect their searches to find materials on exactly what they are looking for; they want relevant results.5 * * * users don’t understand the difference in scope between the catalog and a&i services (or the catalog, databases, digitized collections, and free scholarly content).6 * * * it is our responsibility to assist our users in finding what they need without demanding that they acquire specialized knowledge or select among an array of “silo” systems whose distinctions seem arbitrary . . . the continuing proliferation of formats, tools, services, and technologies has upended how we arrange, retrieve, and present our holdings. our users expect simplicity and immediate reward and amazon, google, and itunes are the standards against which we are judged. our current systems pale beside them.7 * * * q: if you could provide one piece of advice to your library, what would it be? a: just remember that students are less informed about the resources of the library than ever before because they are competing heavily with the internet.8 additional factors sell the idea of web-scale discovery. obviously, something must be discoverable for it to be used (and of value) to a researcher; ideally, content should be easily discoverable. since these new services index content that previously was housed in dozens or hundreds of individual silos, they can greatly facilitate the search process for many research purposes. libraries often spend large sums of money to license and purchase content, sums that often increase annually. any tool that holds the potential to significantly increase the discovery and use of such content should cause libraries to take notice. at time of writing, early research is beginning to indicate that these tools can increase discovery. doug way compared link-resolver-database and full-text statistics prior to and after grand valley state university’s implementation of the summon webscale discovery service.9 his research suggests that the service was both broadly adopted by the university’s community and that it has led to an increase in their library’s electronic resource discovery and use. willamette university implemented worldcat local, and bill kelm presented results that showed an increase in both ill requests as well as use of the library’s electronic resources.10 from another angle, information-literacy efforts focus on connecting users to “legitimate” content and providing researchers the skills to identify content quality and legitimacy. given that these web-scale discovery services include or even primarily focus on indexing a large amount of scholarly research, such services can serve as another tool in the library’s arsenal. results retrieved from these services—largely content licensed or purchased by libraries—is accurate, relevant, and vetted, compared to the questionable or opinionated content that may often be returned through a web search engine query. several of the services currently allow a user to refine results to just categorized as peer-reviewed or scholarly. the internal academic library perspective: genesis of the unlv libraries discovery task force the following sections of this article begin with a focus on the internal unlv library perspective—from early discussions focused on the broad topic of discovery to establishing a task investigations into library web-scale discovery services | vaughan 35 force charged to identify, research, evaluate, and recommend a potential service for purchase. throughout this process, and as detailed below, communication with and feedback from the variety of library staff was essential in ensuring success. given the increasing vitality of content in electronic format, and the fact that such content was increasingly spread across multiple access points or discovery systems, in late 2008 the university of nevada las vegas (unlv) libraries began an effort to engage library staff in information discovery and how such discovery would ideally occur in the future. related to the exponential growth of content in electronic format, traditional technical-services functions of cataloging and acquisitions were changing or would soon change, not just at unlv, but throughout the academic library community. coinciding with this, the libraries were working on drafting their 2009–11 strategic plan and wanted to have a section highlighting the importance of information discovery and delivery with action items focused on improving this critical responsibility of libraries. in spring 2009, library staff were given the opportunity to share with colleagues a product or idea, related to some aspect of discovery, which they felt was worthy of further consideration. this event, open to unlv libraries staff and other nevada colleagues, was titled the discovery mini-summit, and more than a dozen participants shared their ideas, most in a poster-session format. one of the posters focused on serial solutions summon, an early entrant into the vendor web-scale discovery service landscape. at the time, it was a few months from public release. other posters included topics such as the flickr commons (cultural heritage and academic institutions exposing their digital collections through this popular platform), and a working prototype of a homegrown, open-source federated search approach searching across various subscribed databases. in august 2009, the dean of the unlv university libraries charged a ten-person task force to investigate and evaluate web-scale discovery services with the ultimate goal of providing a final recommendation for potential purchase. representation on the task force included three directors and a broad cross section of staff from across the functional areas of the library, including back-of-the-house and public-service operations. the director of library technologies, and author of this article, was tasked with drafting a charge and chairing the committee; once charged, the discovery task force worked over the next fifteen months to research, evaluate, and ultimately provide a recommendation regarding a web-scale discovery service. to help illustrate some of the events described, a graphical timeline of activities is presented as appendix a; the original charge appears as appendix b. in retrospect, the initial target date of early 2010 to make a recommendation was naive, as three of the five products ultimately identified and evaluated by the task force weren’t publicly released until 2010. several boundaries were provided within the charge, including the fact that the task force was not investigating and evaluating traditional federated search products. the libraries had had a very poor experience with federated search a few years earlier, and the shortcomings of the traditional federated search approach—regardless of vendor—are well known. the remainder of this article discusses the various steps taken by the discovery task force in evaluating and researching web-scale discovery services. while many libraries have begun to implement the webscale discovery services evaluated by this group, many more are currently at the learning and evaluation stage, or have not yet begun. many libraries that have already implemented a commercial service likely went through an evaluation process, but perhaps not at the scale conducted by the unlv libraries, if for no other reason than the majority of commercial services are extremely new. even in early 2010, there was less competition, fewer services to evaluate, information technology and libraries | march 2012 36 fewer vendors to contact, and fewer early adopters from whom to seek references. fortunately, the initial target date of early 2010 for a recommendation was a soft target, and the discovery task force was given ample time to evaluate the products. based on presentations given by the author in 2010, it can’t be presumed that an understanding of web-scale discovery—or the awareness of the commercial services now available—is necessarily widespread. in that sense, it’s the author’s hope and intent that information contained in this article can serve as a primer, or a recipe, for those libraries wishing to learn more about web-scale discovery and perhaps begin an evaluation process of their own. while research exists on federated search technologies within the library environment, the author was unable to find any peer-reviewed published research on the evaluation model and investigations for vendor produced web-scale discovery services as described in this paper. however, some reports are available on the open web, providing some insights into web-scale discovery evaluations led by other libraries, such as two reports provided by oregon state university. the first, dated march 2009, describes a task force whose activities included “scrutinize wcl [worldcat local], investigate other vendors’ products, specifically serials solutions’ summon, the recently announced federated index discovery system; ebsco’s integrated search; and innovative interfaces’ encore product, so that a more detailed comparison can be done,” and “by march 2010, communicate . . . whether wcl or another discovery service is the optimal purchase for osu libraries.”11 note that in 2009, encore existed as a next-generation discovery layer, and it had an optional add on called “encore harvester,” which allows for the harvesting of digital local collections. the report cites the university of michigan’s evaluation of wcl, and adds their additional observations. the march 2009 report provides a features comparison matrix for worldcat local, encore, summon, and libraryfind (an open-source search tool developed at osu that provides federated searching for selected resources). feature sets include the areas of search and retrieval, content, and added features (e.g., book covers, user tagging, etc.). the report also describes some usability testing involving wcl and integration with other local library services. a second set of investigations followed “in order to provide the task force with an opportunity to more thoroughly investigate other products” and is described in a second report provided at the end of 2009.12 at the time of both phases of this evaluation (and drafted reports) three of the web-scale discovery products had yet to enter public release. the december 2009 report focused on the two released products, serials solutions summon and worldcat local, and includes a feature matrix like the earlier report, with the added feature set of “other,” which included the features of “clarity of display,” “icons/images,” and “speed.” the latter report briefly describes how they obtained subject librarian feedback and the pros and cons observed by the librarians in looking at summon. it also mentions obtaining feedback from two early adopters of the summon product, as well as obtaining feedback from librarians whose library had implemented worldcat local. apart from the oregon reports, some other reports on evaluations (or selection) of a particular service, or a set of particular services, are available, such as the university of michigan’s article discovery working group, which submitted a final report in january 2010.13 activity: understanding web-scale the first activity of the discovery task force was to educate the members, and later, other library colleagues, on web-scale discovery. terms such as “federated search,” “metasearch,” “next investigations into library web-scale discovery services | vaughan 37 generation catalogs,” and “discovery layers” had all come before, and “web-scale” was a rather new concept that wasn’t widely understood. the discovery mini summit served as a springboard that perhaps more by chance than design introduced to unlv library staff what would later become more commonly known as web-scale discovery, though even we weren’t familiar with the term back in spring 2009. in fall 2009, the discovery task force identified reports from entities such as oclc, ithaka, and reports prepared for the library of congress highlighting changing user behavior and expectations; these reports helped form a solid foundation for understanding the “whys” related to web-scale discovery. additional registration and participation in sponsored web-scale discovery webcasts and meeting with vendors at library conferences helped further the understanding of web-scale discovery. after the discovery task force had a firm understanding of web-scale discovery, the group hosted a forum for all library staff to help explain the concept of web-scale discovery and the role of the discovery task force. specifically, this first forum outlined some key components of a web-scale discovery service, discussed research the task force had completed to date, and outlined some future research and evaluation steps. a summary of these steps appears in the timeline in appendix a. time was allowed for questions and answers, and then the task force broadcast several minutes of a (then recent) webcast talking about web-scale discovery. as part of its education role, the discovery task force set up an internal wiki-based webpage in august 2009 upon formation of the group, regularly added content, and notified staff when new content was added. a goal of the task force was to keep the evaluative process transparent, and over time the wiki became quite substantial. links to “live” services were provided on the wiki. given that some services had yet to be released, some links were to demo sites or sites of the closest approximation available, i.e., some services yet to be released were built on an existing discovery layer already in general release, and thus the look, feel, and functionality of such services was basically available for staff review. the wiki also provided links to published research and webcasts on web-scale discovery. such content grew over time as additional webscale discovery products entered general release. in addition to materials on particular services, links were provided to important background documents and reports on topics related to the user discovery experience and user expectations for search, discovery, and delivery. discovery task force meeting notes and staff survey results were posted to the wiki, as were evaluative materials such as information on the content-overlap analysis conducted for each service. announcements to relevant vendor programs at the american library association’s annual conference were also posted to the wiki. activity: initial staff survey as noted above, when the task force began its work, only two products (out of five ultimately evaluated) were in general release. as more products entered public release, a next step was to invite vendors onsite to show their publicly released product, or a working, developed prototype nearing initial public release. to capture a sense of the library staff ahead of these vendor visits, the discovery task force conducted the first of two staff surveys. the 21-question survey consisted of a mix of “rank on a scale” questions, multiple-choice questions, and free-text response questions. both the initial and subsequent surveys were administered through the online surveymonkey tool. respondents were allowed to skip any question they wished. the survey was broken into three broad topical areas: “local library customization capabilities,” “end user aspect: information technology and libraries | march 2012 38 features and functionality,” and “content.” the survey had an average response rate of 47 staff, or 47% of the library’s 100-strong workforce. the survey questions appear in appendix c. in hindsight, some of the questions could have benefitted from more careful construction. that said, there was a conscious juxtaposition of differing concepts within the same question—the task force did not want to receive a set of responses in which all library staff felt it was important for a service to do everything—in short, to be all things to all people. forcing staff to rate varied concepts within a question could provide insights into what they felt was really important. a brief summary of some key questions for each section follows. as an introduction, one question in the survey asked staff to rate the relative importance of each overarching aspect related to a discovery service (customization, end user interface, and content). staff felt content was the most critical aspect of a discovery service, followed by the end-user interface, followed by the ability to heavily customize the service. a snapshot of some of the capabilities library staff thought were important (or not) is provided in table 1. web-scale capabilities sa a n d sd physical item status information 81.6% 18.4% publication date sort capability 75.5% 24.5%

investigations into library web-scale discovery services | vaughan 39 none of the results was surprising, other than perhaps the low interest or indifference in several web 2.0 community features, such as the ability for users to provide ratings, reviews, or tags for items, and even a tag cloud. the unlv libraries already had a next-generation catalog offering these features, and they have not been heavily used. even if there had been an appreciable adoption of these features by end users in the next-generation catalog for a web scale discovery service they are perhaps less applicable—it’s probably more likely that users would be less inclined to post reviews and ratings for an article, as opposed to a monograph—and article-level content vastly outnumbers book-level content with web-scale discovery services. the final survey section focused on content. one question asked about the incorporation of ten different information types (sources) and asked staff to rank how important it was that a service include such content. results are provided in table 2. a bit surprisingly, inclusion of catalog records was seen as most important. not surprisingly, full-text and a&i content from subscription resources were ranked very highly. it should also be noted that at the time of the survey, the institutional repository was in its infancy with only a few sample records, and awareness of this resource was low among library staff. another question listed a dozen existing publishers (e.g., springer, elsevier, etc.) deemed important to the libraries and asked staff to rank the importance that a discovery service index items from these publishers on a four point scale from “essential” to “not important.” results showed that all publishers were ranked as essential and important. related to content, 83.8 percent of staff felt that it was preferable for a service to de-dupe records such that the item appears once in the returned list of results; 14.6 percent preferred that the service not de-dupe results. information source rating average ils catalog records 1.69 majority of full-text articles / other research contained in vendorlicensed online resources

after the first staff survey was concluded, the discovery task force hosted another library forum to introduce and “test drive” the five vendor services in front of library staff. this session was scheduled just a few weeks ahead of the onsite vendor visits to help serve as a primer to engage library staff and get them actively thinking about questions to ask the vendors. the task force information technology and libraries | march 2012 40 distributed notecards at the forum and asked attendees to record any specific questions they had about a particular service. after the forum, specific questions related to the particular products were collected; 28 questions were collected, and they helped inform future research for those questions for which the task force did not at the time have an answer. questions ran the gamut and collectively touched on all three areas of evaluation. activity: second staff survey within a month after the five vendor onsite visits, a content analysis of the overlap between unlv licensed content and content indexed by the discovery services was conducted. after these steps, a second staff survey was administered. this second staff survey had questions focused on the same three functional areas as the first staff survey: local library customization features, end user features and functionality, and content. since the vendor visits had taken place and users could now understand the questions in the context of the products, questions were asked from the perspective of each product, e.g., “please rate on a five point likert scale whether each discovery service appears to adequately cover a majority of the critical publisher titles (worldcat local, summon, eds, encore synergy, primo central).” in addition, there were free-text questions focused on each individual product allowing colleagues to share additional, detailed thoughts. the second survey totalled 25 questions and had an average response rate of 18 respondents, or about 18 percent of library staff. several staff conducted a series of sample searches in each of the services and provided feedback of their findings. though this was a small response rate, two of the five products rose to the top, a third was a strong contender, and two were seen as less desirable. the lower response rate is perhaps indicative of several things. first, not all staff had attended the onsite vendor demonstrations or had taken the time to test drive the services via the links provided on the discovery task force wiki site. second, some questions were more appropriately answered by a subset of staff. for example, the content questions might best be matched to those with reference, collection development, or curriculum and program liaison duties. finally, intricate details emerged once a thorough analysis of the vendor services was commenced. the first survey was focused more on the philosophy of what was desirable; the second survey took this a step further and asked how well each product matched such wishes. discovery services are changing rapidly with respect to interface updates, customization options, and scope of content. as such, and also reflective of the lower response rate, the author is not providing response information nor analysis for this second survey within this article. however, results may be provided upon specific request to the author. the questions themselves for the second staff survey are significant, and they could help serve as a model for other libraries evaluating existing services on the market. as such, questions appear in appendix d. activity: early adopter references one of the latter steps in the evaluation process from the internal academic library perspective was to obtain early adopter references from other academic library customers. a preliminary shortlist was compiled through a straw vote of the discovery task force—and the results of the vote showed a consensus. this vote narrowed down the discovery task force’s list of services still in contention for a potential purchase. this shortlist was based on the growing mass of research conducted by the discovery task force and informed by the staff surveys and feedback to date. three live customers were identified for each service that had made the shortlist, and the task investigations into library web-scale discovery services | vaughan 41 force successfully obtained two references for each service. reference requests were intensive and involved a set of two dozen questions that references either responded to in writing or answered during scheduled conference calls. to help libraries conducting or interested in conducting their own evaluation and analysis of these services, this list of questions appears in appendix e. the services are so new that the live references weren’t able to comprehensively answer all the questions—they simply hadn’t had sufficient time to fully assess the service they’d chosen to implement. still, some important insights were gained about the specific products and, at the larger level, discovery services as a whole. as noted earlier, discovery services are changing rapidly in the sense of interface updates, customization options, and scope of content. as such, the author is not providing product specific response information or analysis of responses for each specific product—such investigations and interpretations are the job of each individual library seriously wishing to evaluate the services to help decide which product seems most appropriate for its particular environment. several broad insights merit notice, and they are shared below. regarding a question on implementation (though some challenges were mentioned with a few responders), nothing reached the threshold of serious concern. all respondents indicated the new discovery service is already the default or primary search box on their website. one section of the early adopter questions focused on content. the questions in this area seemed a bit challenging for the respondents to provide lots of detail. in terms of “adequately covering a majority of the important library titles,” respondents varied from “too early to tell,” “it covers many areas but there are some big names missing,” to two of the respondents answering simply, “yes.” several respondents also clearly indicated that the web-scale discovery service is not the “beginning and ending” for discovery, a fact that even some of the discovery vendors openly note. for example, one respondent indicated that web-scale discovery doesn’t replace remote federated searching. a majority (not all) of the discovery vendors also have a federated search product that can, to varying degrees, be integrated with their preharvested, centralized, index-based discovery service. this allows additional content to be searched because such databases may include content not indexed within the web-scale discovery service. however, many are familiar with the limitations of federated search technologies: slow speed, poor relevancy ranking of results, and the need to configure and maintain sources and targets. such problems remain with federated search products integrated with web-scale discovery services. another respondent indicated they were targeting their discovery service at undergraduate research needs. another responded, “as a general rule, i would say the discovery service does an excellent job covering all disciplines. if you start really in-depth research in a specific discipline, it starts to break down. general searches are great . . . dive deeper into any discipline and it falls apart. for example, for a computer science person, at some point they will want to go to acm or ieee directly for deep searches.” related to this, “the catalog is still important, if you want to do a very specific search for a book record, the catalog is better. the discovery service does not replace the catalog.” in terms of satisfaction with content type (newspapers, articles, proceedings, etc.), respondents seemed generally happy with the content mix. a range of responses were received, such as “doesn’t appear to be a leaning one way or another, it’s a mix. some of these things depend on how you set the system up, as there is quite a bit of flexibility; the library has to make a decision on what they want searched.” another example was that “the vendor has been working very hard to balance content types and i’ve seen a lot of improvement,” “no imbalance, results seem pretty well rounded.” another responded, “a common complaint is that newspapers and book reviews dominate the search results, but that is much more a function of search algorithms then the amount of content in the index.” information technology and libraries | march 2012 42 when asked about positive or critical faculty feedback to the service, several respondents indicated they hadn’t had a lot of feedback yet. one indicated they had anecdotal feedback. another indicated they’d received backlash from some users who were used to other search services (but also added that it was no greater than backlash from any other service they’d implemented in the past—and so the backlash wasn’t a surprise). one indicated “not a lot of feedback from faculty, the tendency is to go to databases directly, librarians need to instruct them in the discovery service.” for student feedback, one indicated, “we have received a few positive comments and see increased usage.” another indicated, “reviews are mixed. we have had a lot of feedback thanking us for providing a search that covers articles and books. they like the ability to do one search and get a mix of resources without the search taking a long time. other feedback usually centers around a bug or a feature not working as it should, or as they understand it should. in general, however, the feedback has been positive.” another replied, “comments we receive are generally positive, but we’ve not collected them systematically.” some respondents indicated they had done some initial usability testing on the initial interface, but not the most recent one now in use. others indicated they had not yet conducted usability testing, but it was planned for later in 2010 or 2011. in terms of their fellow library staff and their initial satisfaction, one respondent indicated, “somewhere between satisfied and very satisfied . . . it has been increasing with each interface upgrade . . . our instruction librarians are not planning to use the discovery service this fall [in instruction efforts] because they need more experience with it . . . they have been overall intrigued and impressed by it . . . i would say our organization is grappling more with the implications of a discovery tools as a phenomenon than with our particular discovery service in particular. there seems to be general agreement that it is a good search tool for the unmediated searcher.” another indicated some concerns with the initial interface provided: “if librarians couldn’t figure it out, users can’t figure it out.” another responded, it was “a big struggle with librarians getting on board with the system and promoting the service to students. they continually compare it against the catalog. at one point, they weren’t even teaching the discovery service in bib instruction. the only way to improve things it with librarian feedback; it’s getting better, it has been hard. librarians have a hard time replacing the catalog and changing things that they are used to.” in terms of local customization, responses varied; some libraries had done basically no customization to the out-of-the-box interface, others had done extensive customization. one indicated they had tweaked sort options and added widgets to the interface. another indicated they had done extensive changes to the css. one indicated they had customized the colors, added a logo, tweaked the headers and footers, and created “canned” or preconfigured search boxes searching a subset of the index. another indicated they couldn’t customize the header and footer to the degree they would have liked, but were able to customize these elements to a degree. one respondent indicated they’d done a lot of customization to an earlier version of the interface, which had been rather painstaking, and that much of this broke when they upgraded to the latest version. that said, they also indicated the latest version was much better than the previous version. one respondent indicated it would be nice if the service could have multiple sources for investigations into library web-scale discovery services | vaughan 43 enriched record content so that better coverage could be achieved. one respondent indicated they were working on a complete custom interface from scratch, which would be partially populated with results from the discovery service index (as well as other data sources). a few questions asked about relevancy as a search concept and how well the respondents felt about the quality of returned results for queries. one respondent indicated, “we have been able to tweak the ranking and are satisfied at this point.” another indicated, “overall, the relevance is good – and it has improved a lot.” another noted, “known item title searching has been a problem . . . the issues here are very predictable – one word titles are more likely to be a problem, as well as titles with stopwords,” and noted the vendor was aware of the issue and was improving this. one noted, “we would like to be able to experiment with the discovery service more – and noted, “no relevancy algorithm control.” another indicated they looked to investigate relevance more once usability studies commenced, and noted they worked with the vendor to do some code changes with the default search mechanism. one noted that they’d like to be able to specify some additional fields that would be part of the algorithm associated with relevancy. another optimistically noted “as an early adopter, it has been amazing to see how relevance has improved. it is not perfect, but it is constantly evolving and improving.” a final question asked simply, “overall, do you feel your selection of this vendor’s product was a good one? do you sense that your users – students and faculty – have positively received the product?” for the majority of responses, there was general agreement from the early adopters that they felt they’d made the right choice. one noted that it was still early and the evaluation is still a work in progress, but felt it has been positively received. the majority were more certain, “yes, i strongly feel that this was the right decision . . . as more users find it, i believe we will receive additional positive feedback,” “yes, we strongly believe in this product and feel it has been adopted and widely accepted by our users,” “i do feel it was a good selection.” the external perspective: dialog with web-scale discovery vendors the preceding sections focused on an academic library’s perspective on web-scale discovery services—the thoughts, opinions, preferences, and vetting activities involving library staff. the following sections focus on the extensive dialog and interaction with the vendors themselves, regardless of the internal library perspective, and highlight the thorough, meticulous research activities conducted on five vendor services. the discovery task force sought to learn as much about the each service as possible, a challenging proposition given the fact that at the start of investigations, only two of five services had been released, and, unsurprisingly, very little research existed. as such, it was critical to work with vendors to best understand their services, and how their service compared to others in the marketplace. broadly summarized efforts included identification of services, drafting of multiple comprehensive question lists distributed to the vendors, onsite vendor visits, and continual tracking of service enhancements. activity: vendor identification over the course of a year’s work, the discovery task force executed several steps to systematically understand the vendor marketplace—the capabilities, content considerations, development cycles, and future roadmaps associated with five vendor offerings. given that the information technology and libraries | march 2012 44 task force began their work when only two of these services were in public release, there was no manual, recipe, or substantial published research to rely on. the beginning, for the unlv libraries, lie in identification of the services—one must first know the services to be evaluated before evaluation can commence. as mentioned previously, the discovery mini-summit held at the unlv libraries highlighted one product—serial solutions summon; the only released product at the time of the mini-summit was worldcat local. while no published peer-reviewed research highlighting these new web-scale discovery services existed, press and news releases did exist for the three to-be-released services. such releases shed light on the landscape of services that the task force would review—a total of five services, from the first-to-market, worldcat local, to the most recent entrant, primo central. oclc worldcat local, released in november 2007, can be considered the first web-scale discovery service as defined in this research; the experience of an early pilot partner (the university of washington) is profiled in a 2008 issue of library technology reports.14 in the uw pilot, approximately 30 million article-level items were included with the worldcat database. another product, serials solutions summon, was released in july 2009, and together these two services were the only ones publicly released when the discovery task force began its work. the task force identified three additional vendors each working on their own version of a web-scale discovery service; each of these services would enter initial general release as the task force continued its research: ebsco eds in january 2010, innovative interfaces encore synergy around may 2010, and ex libris primo central in june 2010. while each of these three were new in terms of web-scale discovery capabilities, each was built, at least in part, on earlier systems from the vendors. eds draws heavily from the ebscohost interface (the original version of which dates back to the 1990s), while the base encore and base primo systems were next-generation catalog systems that debuted in 2007. activity: vendor investigations after identification of existing and under development discovery services, a next step in unlv’s detailed vendor investigations included the creation of a uniform, comprehensive question list sent to each of the five vendors. the discovery task force ultimately developed a list of 71 questions divided into nine functional areas, as follows, with an example question: section 1: background. “when did product development begin (month, year)?” section 2: locally hosted systems and associated metadata. “with what metadata schemas does your discovery platform work? (e.g., marc, dublin core, ead, etc.)” section 3: publisher/aggregator coverage (full text and citation content). “with approximately how many publishers/aggregators have you forged content agreements ?” section 4: records maintenance and rights management. “how is your system initialized with the correct set of rights management information when a new library customer subscribes to your product?” investigations into library web-scale discovery services | vaughan 45 section 5: seamlessness & interoperability with existing content repositories. “for ils records related to physical holdings, is status information provided directly within the discovery service results list?” section 6: usability philosophy. “describe how your product incorporates published, established best practices in terms of a customer focused, usable interface.” section 7: local “look & feel” customization options. “which of the following can the library control: color scheme; logo / branding; facet categories and placement; etc.” section 8: user experience (presentation, search functionality, and what the user can do with the results). “at what point does a user leave the context and confines of the discovery interface and enter the interface of a different system, whether remote or local?” section 9: administration module & statistics. “describe in detail the statistics reporting capabilities offered by your system. does your system provide the following sets of statistics . . .” all vendors were given 2–3 weeks to respond, and all vendors responded. it was evident from the uneven level of responses to the questions that the vendors were at different developmental states with their products. some vendors were still 6–9 months away from initial public release; some were not even firm on when their service would enter release. it was also observed that some vendors were less explicit in the level of detail provided, reflective of, or in some cases perhaps regardless of, development state. a refined subset of the original 71 questions appears as a list of 40 questions in appendix f. apart from the detailed question list, various sets of free and licensed information on these discovery services are available online, and the task force sought to identify and digest the information. the charleston advisor has conducted interviews with several of the library webscale discovery vendors on their products, including ebsco,15 serials solutions,16 and ex libris.17 these interviews, each around a dozen questions, ask the vendors to describe their product, how it differs from other products in the marketplace, and include questions on metadata and content—all important questions. an article by ronda rowe reviews summon, eds, and worldcat local, and provides some analysis of each product on the basis of content, user interface and searchability, pricing, and contract options.18 it also provides a comparison of 24 product features provided by these three services, such as “search box can be embedded in any webpage,” “local branding possible,” and “supports social networking.” a wide variety of archived webcasts, many provided by library journal, are available through free registration, and new webcasts are being offered at time of writing; these presentations to some degree touch on discussions with the discovery vendors, and are often moderated or include company representatives as part of the discussion group.19 several libraries have authored reports and presentations that, at least partially, discuss information on particular services gained through their evaluations, which include dialog with the vendors.20 vendors themselves each have a section on their corporate website devoted to their service. information provided on these websites ranges from extremely brief to, in the case of worldcat local, very detailed and informative. in addition, much can be gained by “test-driving” live implementations. as such, a listing of vendor website addresses information technology and libraries | march 2012 46 providing more information as well as a list of sample, live implementations is provided in appendix g. activities: vendor visits and content overlap analysis each of the five vendors visited the unlv libraries in spring 2010. vendor visits all occurred within a nine-day span; visits were intentionally scheduled close to each other to keep things fresh in the minds of library staff, and such proximity would help with product comparisons. vendor visits lasted approximately half a day, and each vendor visit often included the field or regional sales representative as well as a product manager or technical expert. vendor visits included a demonstration and q&a for all library staff as well as invited colleagues from other southern nevada libraries, a meeting with the discovery task force, and a meeting with technical staff at unlv responsible for website design and application development and customization. vendors were each given a uniform set of fourteen questions on topics to address during their visit; these appear in appendix h. questions were divided into the broad topical areas of content coverage, end user interface and functionality, and staff “control” over the end user interface. on average, approximately 30–40 percent of the library staff attended the open vendor demo and q & a session. shortly after the vendor visits, a content-overlap analysis comparing unlv serials holdings with indexed content in the discovery service was sought from each vendor. given that the amount of content indexed by each discovery service was growing (and continues to grow) extremely rapidly as new publisher and aggregator content agreements are signed, this content-overlap analysis was intentionally not sought at an earlier date. some vendors were able to provide detailed coverage information against our existing journal titles (unlv currently subscribes to approximately 20,000 e-journals and provides access to another 7,000+ open-access titles). for others, this was more difficult. recognizing this, the head of collection development was asked to provide a list of the “top 100” journal titles for unlv based on such factors as usage statistics and whether the title was a core title for part of the unlv curriculum. the remaining vendors were able to provide content coverage information against this critical title list. four of the five products had quite comprehensive coverage (more than 80 percent) of the unlv libraries’ titles. while outside the scope of this article, “coverage” can mean different things for different services. driven by the publisher agreements they are able to secure, some discovery services may have extensive coverage for particular titles (such as the full text, abstracts, author-supplied keywords, subject headings, etc.), whereas other services, while covering the same title, may have “thinner” metadata, such as basic citation information (article title, publication title, author, publication date, etc.). more discussion on this topic is present in the january 2011 library technology reports on library web-scale discovery services.21 activity: product development tracking one aspect of web-scale discovery services, and the next-generation discovery layers that preceded them, is a rapid enhancement cycle, especially when juxtaposed against the turnkeystyle ils system that dominated library automation for many years. as an example, minor enhancements are provided by serials solutions to summon approximately every three to four weeks; provided by ebsco to ebsco discovery service approximately every three months; and investigations into library web-scale discovery services | vaughan 47 provided by ex libris to primo/primo central approximately every three months. many vendors unveil updates coinciding with annual library conferences, and 2010 was no exception. in late summer/early fall 2010, the discovery task force had conference calls or onsite visits with several of the vendors with a focused discussion on new enhancements and changes to services as well as to obtain answers to any questions that arose since their last visit several months earlier. since the vendor visits in spring 2010, each service had changed, and two services had unveiled significantly different and improved interfaces. the discovery task force’s understanding of web-scale discovery services had expanded greatly since starting their work. coordinated with the second series of vendor visits and discussions, an additional list of more than two dozen questions, recognizing this refined understanding, was sent to the majority of vendors. a portion of these questions are provided as part of the refined list of questions presented in appendix f. this second set of questions dealt with complex discussions of metadata quality, such as what level of content publishers and aggregators were providing for indexing purposes, e.g., full text, abstracts, table of contents, author-supplied keywords or subject headings, or particular citation and record fields), and also the vendor’s stance on content neutrality, i.e., whether they are entering into exclusive agreements with publishers and aggregators, and, if the discovery service vendor is owned by a company involved with content, if that content is promoted or weighted more heavily in result sets. other questions dealt with such topics as current install base counts and technical clarifications about how their service worked. in particular, the questions related to content were tricky for many (not all) of the vendors to address. still, the discovery task force was able to get a better understanding of how things worked in the evolving discovery environment. combined with the internal library perspective and the early adopter references, information gathered from vendors provided the necessary data set to submit a recommendation with confidence. activity: recommendation by mid-fall 2010, the discovery task force had conducted and had at their disposal a tremendous amount of research. recognizing how quickly these services change and the fact that a cyclical evaluation could occur, the task force members felt they had met their charge. if all things failed during the next phase—implementation—at least no one would be able to question the thoroughness of the task force’s efforts. unlike the hasty decision, which in part led to a less than stellar experience with federated search a few years earlier, the evaluation process to recommend a new web-scale discovery service was deliberate, thorough, transparent, and vetted with library stakeholders. given the discovery task force was entering its final phase, official price quotes were sought from each vendor. each task force member was asked to develop a pro/con list for all five identified products based on the knowledge that was gained. these lists were anonymized and consolidated into a single, extensive pro/con list for each service. some of the pros and cons were subjective (such as the interface aesthetics), some were objective (such as a particular discovery service not offering a desired feature). at one of the final meetings of the task force, members reaffirmed the three top contenders, indicated the other two were no longer under consideration and, afterward, were asked to rank their first, second, and third choices for the remaining services. while complete consensus wasn’t achieved, there was a resounding first choice, second choice, and third information technology and libraries | march 2012 48 choice. the task force presented a summary of findings at a meeting open to all library staff. this meeting summarized the research and evaluation steps the task force had conducted over the past year, framed each of the three shortlisted services by discussing some strengths and weaknesses of each service as observed by the task force, and sought to answer any questions from the library at large. prior to drafting the final report and making the recommendation to the dean of libraries, several task force members led a discussion and final question and answer at a libraries’ cabinet meeting, one of the high-level administrative groups at the unlv libraries. vetting by this body represented the last step related to the discovery task force’s investigation, evaluation, and recommendation for purchase of a library web-scale discovery service. the recommendation was broadly accepted by the library cabinet, and shortly afterward the discovery task force was officially disbanded, having met its goal of investigating, evaluating, and making a recommendation for purchase of a library web-scale discovery service. next steps the dialog above describes the research, evaluation, and recommendation model used by the unlv libraries to select a web-scale discovery service. such a model and the associated appendixes could serve as a framework, with some adaptations perhaps, for other libraries considering the evaluation and purchase of a web-scale discovery service. together, the discovery task force’s internal and external research and evaluation provided a substantive base of knowledge on which to make a recommendation. after its recommendation, the project progressed from a research and recommendation phase to an implementation phase. the libraries’ cabinet brainstormed a list of more than a dozen concise implementation bullet points—steps that would need to be addressed—including the harvesting and metadata mapping of local library resources, local branding and some level of customization work, and integration of the web-scale discovery search box in the appropriate locations on the libraries’ website. project implementation co-managers were assigned (the director of technical services and the web technical support manager), as well as key library personnel who would aid in one or more implementation steps. in january 2011, the implementation commenced, with an expected public launch of the new service planned for mid-2011. the success of a web-scale discovery service at the unlv libraries is a story yet to be written, but one full of promise. acknowledgements the author wishes to thank the other members of the unlv libraries’ discovery task force in the research and

| march 2012 53 appendix b. discovery task force charge discovery task force charge informed through various efforts and research at the local and broader levels, and as expressed in the libraries 2010/12 strategic plan, the unlv libraries have the desire to enable and maximize the discovery of library resources for our patrons. specifically, the unlv libraries seek a unified solution which ideally could meet these guiding principles: • creates a unified search interface for users pulling together information from the library catalog as well as other resources (e.g. journal articles, images, archival materials). • enhances discoverability of as broad a spectrum of library resources as possible • intuitive: minimizes the skills, time, and effort needed by our users to discover resources •supports a high level of local customization (such as accommodation of branding and usability considerations) • supports a high level of interoperability (easily connecting and exchanging data with other systems that are part of our information infrastructure) •demonstrates commitment to sustainability and future enhancements •informed by preferred starting points as such, the discovery task force advises libraries administration on a solution that appears to best meet the goal of enabling and maximizing the discovery of library resources. a bulk of the work will entail a marketplace survey and evaluation of vendor offerings. charge specific deliverables for this work include: 1. identify vendor next generation discovery platforms, whether established and currently on the market, or those publicized and at an advanced stage of development, with an expectation of availability within a year’s time. identify & create a representative list of other academic libraries which have implemented or purchased currently available products. 2. create a checklist / criteria of functional requirements / desires for a next generation discovery platform. 3. create lists of questions to distribute to potential vendors and existing customers of next generation discovery platforms. questions will focus on broad categories such as the following: a. seek to understand how content hosted in our current online systems (iii catalog, contentdm, locally created databases, vendor databases, etc.) could/would (or not be able investigations into library web-scale discovery services | vaughan 54 to) be incorporated or searchable within the discovery platform. apart from our existing online systems as we know them today, the task force will explore, in general terms, how new information resources could be incorporated into the discovery platform. more explicitly, the task force will seek an understanding of what types of existing records are discoverable within the vendor’s next generation discovery platform, and seek an understanding of what basic metadata must exist for an item to be discoverable. b. seek to understand whether the solution relies on federated search, the creation of a central site index via metadata harvesting, or both, to enable discovery of items. c. additional questions, such as pricing, maintenance, install base, etc. 4. evaluate gathered information and seek feedback from library staff. 5. provide to the dean’s directs a final report which summarizes the task force findings. this report will include a recommended product(s) and a broad, as opposed to detailed, summary of workload implications related to implementation and ongoing maintenance. the final report should be provided to the dean’s directs by february 15, 2010. boundaries the work of the task force does not include: • detailing the contents of “hidden collections” within the libraries and seeking to make a concrete determination that such hidden collections, in their current form, would be discoverable via the new system. • conducting an inventory, recommending, or prioritizing collections or items which should be cataloged or otherwise enriched with metadata to make them discoverable. • coordination with other southern nevada nshe entities. • an ils marketplace survey. the underlying innovative millennium system is not being reviewed for potential replacement. • implementation of a selected product.

the local library, how often do you harvest information to account for record updates, modifications, deletions? can the local library invoke a manual harvest of locally hosted resource records on a per-resource basis (e.g. from a selected resource – for example, if the library launches a new digital collection and want the records to be available in the new discovery platform shortly after they are available in our local digital collection management system, is there a mechanism to force a harvest prior to the next regularly scheduled harvest routine? after harvesting, how long does it

indexing purposes, by the “majority” of major publishers/aggregators with which you have forged agreements. please describe to what degree the following elements play a role in your discovery service: a. “basic” bibliographic information (article title/journal title/author/publication information) b. subject descriptors c. keywords (author supplied?) d. abstracts (author supplied?) e. full text 15. topical content strength do you feel there is a particular content area that you feel the service covers especially well or leans heavily toward (e.g. humanities, social sciences, sciences). do you feel there is a particular content type that you feel the service covers very well or leans heavily toward (scholarly journal content, mainstream journal content, newspapers, conference proceedings). what subject / content areas, if any, do you feel the service may be somewhat weak? are there current efforts to mitigate these weaknesses (e.g. future publisher agreements on the horizon)? 16. major publisher content agreements. are there major publisher agreements that you feel are especially significant for your service? if so, which publishers, and why (e.g. other discovery platform vendors may not have such agreements with those particular providers; the amount of content was so great that it greatly augmented the size and scope of your service; etc.) investigations into library web-scale discovery services | vaughan 74 17. content considered key by local library (by publisher). following is a list of some major publishers whose content the library licenses which is considered “key.” has your company forged agreements with these publishers to harvest their materials. if so please describe in general the scope of the agreement. how many titles are covered for each publisher? what level of metadata are they providing to you for indexing purposes (e.g. basic citation level metadata – title, author, publication date; abstracts; full text). a. ex. elsevier b. ex. sage c. ex. taylor and francis d. ex. wiley / blackwell 18. content considered key by local library (by title). following is a list of some major journal / newspaper titles whose content the library

article) can be provided by multiple sources (e.g. the original publisher of the journal itself, an open access repository, a database / aggregator, another database / aggregator, etc.), please provide some general comments on how records are built within your discovery service. for example: a. you have an agreement with a particular publisher/aggregator and they agree to provide you with rich metadata for their content, perhaps even provide you with indexing they’ve already done for their content, and may even provide you with the full text for you to be able to “deep index” their content. b. you’ve got an agreement with a particular publisher who happens to be the only publisher/provider of that content. they may provide you rich info, or they may provide you rather weak info. in any case, you choose to incorporate this into your service, as they are the only provider/publisher of the info. or, information technology and libraries | march 2012 75 alternately, they may not be the only publisher/provider of the info, but they are the only publisher/provider you’ve currently entered into an agreement with for that content. c. for some items appearing within your service, content for those items is provided by multiple different sources whom you’ve made agreements with. in short, there will be in some/many cases of overlap for unique items, such as a particular article title. in such cases, do you create a “merged/composite/super record” -where your service utilizes particular metadata from each of the multiple sources, creating a “strong” single record built from these multiple resources. 23. deduping. related to the question immediately above, please describe your services’ approach (or not) to deduplicating items in your central index. if your service incorporates content for a same unique item from more than one content provider, does your index retrieve and display multiple instances of the same title? or do you create a merged/composite/super record, and only this single record is displayed? please describe. section 4: open access content 24. open access content sources. does your service automatically include (out of the box, no additional charge) materials from open access repositories? if so, could you please list some of the major repositories included (e.g. arxiv e-prints; hindawi publishing corporation; the directory of open access journals; hathi trust materials; etc.). 25. open access content sources: future plans. in addition to the current open access repositories that may be included in your service, are there other repositories whose content you are planning to incorporate in the future? 26. exposure to other libraries’ bibliographic / digital collection / ir content. are ils bibliographic records from other customers using your discovery platform exposed for discoverability in the searchable discovery instance of another customer? are digital collection records? institutional repository records? section 5: relevancy ranking 27. relevancy determination. please describe some of the factors which comprise the determination of relevancy within your service. what elements play a role, and how heavily are they weighted for purposes of determining relevancy? 28. currency. please comment on how heavily currency of an item plays in relevancy determination. does currency weigh more heavily for certain content types (e.g. newspapers)? 29. local library influence. does the local library have any influence or level of control over the relevancy algorithm? can they choose to “bump up” particular items for a search? please describe. 30. local collection visibility. could you please offer some comments on how local content (e.g. ils bibliographic records; digital collections) remains visible and discoverable within the larger pool of content indexed by your service? for example, local content may measures a million items, and your centralized index may cover half a billion items. investigations into library web-scale discovery services | vaughan 76 31. exposure of items with minimal metadata. some items likely have lesser metadata than other items. could you please offer some comments on how your system ensures discoverability for items with lesser or minimal metadata. 32. full text searching. does your service offer the capability for the user to search the fulltext of materials in your service (i.e. are they searching a full text keyword index?) if so, approximately what percentage of items within your service are “deep indexed?” 33. please describe how your system deals when no hits are retrieved for a search. does your system enable “best-match” retrieval – that is, something will always be returned or recommended? what elements play into this determination; how is the user prevented from having a completely “dead-end” search? section 6: authentication and rights management 34. open / closed nature of your discovery solution. does your system offer an unauthenticated view / access? please describe and offer some comments on what materials will not be discoverable/visible for an unauthenticated user. a. licensed full text b. records specifically or solely sourced from abstract and indexing databases c. full citation information (e.g. an unauthenticated user may see just a title; an authenticated user would see fuller citation information) d. enrichment information (such as book image covers, table of contents, abstracts, etc.) e. other 35. exposure of non-licensed resource metadata. if one weren’t to consider and take into account any e-journal/publisher package/database subscriptions & licenses the local library pays for, is there a base index of citation information that’s exposed and available to all subscribers of your discovery service? this may include open access materials, and/or bibliographic information for some publisher / aggregator content (which often requires a local library license to access the full

abstract increasingly sophisticated content management systems (cms) allow librarians to publish content via the web and within the private domain of institutional learning management systems. “libraries as publishers” may bring to mind roles in scholarly communication and open scholarship, but the authors argue that libraries’ self-publishing dates to the first “pathfinder” handout and continues today via commonly used, feature-rich applications such as wordpress, drupal, libguides, and canvas. although this technology can reduce costly development overhead, it also poses significant challenges. these tools can inadvertently be used to create more noise than signal, potentially alienating the very audiences we hope to reach. no cms can, by itself, address the fact that authoring, editing, and publishing quality content is both a situated expertise and a significant, ongoing demand on staff time. this article will review library use of cms applications, outline challenges inherent in their use, and discuss the advantages of embracing content strategy. introduction we tend to look at content management as a digital concept, but it’s been around for as long as content. for as long as humans have been creating content, we’ve been searching for solutions to manage it. the library of alexandria (300 bc to about ad 273) was an early attempt at managing content. it preserved content in the form of papyrus scrolls and codices, and presumably controlled access to them. librarians were the first content managers.1 (emphasis added) content is, and has always been, central to the mission of libraries. content is physical, digital, acquired, purchased, leased, subscribed, and created. “libraries as publishers” may bring to mind roles in scholarly communication and open scholarship, but the authors argue that libraries’ selfpublishing dates to the first mimeographed ‘pathfinder’ handout and continues today via commonly used, feature-rich web content management systems (cmss). libraries use these cmss to support research, teaching, and learning in a variety of day-to-day operations. the sophisticated and complex infrastructure surrounding web-based library content has evolved from the singular, independently hosted and managed “library website” into a “library web ecosystem” comprised of multiple platforms, including integrated library systems, institutional repositories, cmss, and others. multiple cms applications, whether open-source (e.g., wordpress, drupal), institutionally supported (e.g., canvas, blackboard) or library-specific (e.g., springshare’s libguides), are employed by most libraries to power the library’s website and research guides, as well as to make their collections, in any and all formats, discoverable and accessible. mailto:crmcdonald@colorado.edu mailto:heidisb@umich.edu) library-authored web content and the need for content strategy | mcdonald and burkhardt 9 https://doi.org/10.6017/ital.v38i3.11015 library staff at all levels create and publish content through these cms platforms, an activity that is critical to our users discovering what we offer and accomplishing their goals. the cms removes technical bottlenecks and enables subject matter experts to publish content without coding expertise or direct access to a server. this disintermediation has many benefits, enabling librarians to share and interact directly with their communities, and reducing costly development overhead. as with any powerful technology that’s simple to use, effectively implementing a cms is not without pitfalls. through these tools, we can inadvertently create more noise than signal, potentially alienating the very audiences we hope to reach. further, effective management of content and workflows across and among so many platforms is not trivial. distributing web content creation among many authors can quickly lead to numerous challenges requiring expert attention. governance strategies for library-authored web content are rarely addressed in the library literature. this article will review library use of cms applications, outline challenges inherent in their use, and discuss the advantages of embracing content strategy as a framework for library-authored web content governance. content management systems: a definition any conversation on this topic is complicated by the fact that there is both misunderstanding and disagreement regarding the definition of a content management system. in their survey of 149 libraries covering day-to-day website management, including staffing, infrastructure, and organizational structures, bundza et al. observed “[w]hen reviewing the diverse systems mentioned, it is obvious that people defined cmss very broadly.”2 connell surveyed over 600 libraries regarding their use of cmss, defined as “website management tools through which the appearance and formatting is managed separately from content, so that authors can easily add content regardless of web authoring skills.”3 a few respondents “indicated their cms was dreamweaver or adobe contribute” and another “self-identified as a non-cms user but then listed drupal as their web management tool.”4 while the authors find the survey definition itself slightly ambiguous (likely in the service of clarity for survey respondents), we also believe that these responses may hint at an underlying and widespread lack of clarity regarding the technology itself. an early report on potential library use of content management systems by browning and lowndes in 2001 opined that “a cms is not really a product or a technology. it is a catch-all term that covers a wide set of processes that will underpin the ‘next generation’ large-scale website.”5 while technological developments over the last twenty years reveal some limitations to this early characterization, we believe it is fundamentally sound to define the cms primarily through its functions. fulton defined a cms as “an application that enables the shared creation, editing, publish ing, and management of digital content under strict administrative parameters.”6 the authors concur with barker’s (2016) similarly task-based definition: “a content management system (cms) is a software package that provides some level of automation for the tasks required to effectively manage content . . . usually server-based, multi-user . . . [and] interact[ing] with content stored in a information technology and libraries | september 2019 10 repository.”7 browning & lowndes defined the key tasks, or functions, of the cms as encompassing four major categories: authoring, workflow, storage, and publishing.8 barker (2016) also outlined “the big four” of content management as: enterprise content management (e.g., intranets), digital asset management (dam), records management, and web content management (wcm), with wcm defined as “the management of content primarily intended for mass delivery via a website. wcm excels at separating content from presentation and publishing to multiple channels.”9 for the purpose of clarity within the scope of this article, our discussion will primarily focus on content management systems as they are used for wcm, acknowledging that some principles may apply in varying degrees to other categories. the cms and library websites the library literature reveals that, generally speaking, libraries began the transition from telnet and gopher catalog interfaces to launching websites in the 1990s.10 case studies of library websites from this period through the mid-2000s report library website pages increasing at a rapid rate, in some cases doubling or tripling on a yearly basis. 11 a comment from dallis and ryner in regard to their own case study provides a sense of what might be considered typical during this period: “the management of the site was decentralized, and it grew to an estimated 8,000 pages over a period of five years.”12 this proliferation, in turn, spurred focused interest in content management. “web content management (wcm) as a branch of content management (cm) gained importance during the web explosion in the mid-1990s.”13 as early as 2001 there were published laments regarding the state of library websites: institutions are struggling to maintain their web sites. out of date material, poor control over design and navigation, a lack of authority control and the constriction of the webmaster (or even web team) bottleneck will be familiar to many in the he/fe [higher education / further education] sector. the pre-millennial web has been characterized by highly manual approaches to maintenance; the successful and sustainable post-millennial web will have significant automation. one vehicle by which this can be achieved is the cms.14 mach wrote: the special concerns of web maintenance have only multiplied with the increased size and complexity of many library web sites. not only does the single webmaster model no longer work for most libraries, but the static html page is also in jeopardy. many overworked web librarians dream about the instant content updates possible with database-driven site or content management software. but while these technical solutions save staff time, they demand a fair amount of compromise.15 in 2010, fulton noted, “at one time, all institutions [mentioned in her literature review] could effectively manage their sites outside of a cms. however, changing standards combined with uncontrollable growth patterns persuaded them to take steps to prevent prolonged chaos.”16 library-authored web content and the need for content strategy | mcdonald and burkhardt 11 https://doi.org/10.6017/ital.v38i3.11015 changing technology, accessibility, and literacy throughout the early 2000s, advances in consumer technology and in web development (e.g., css, html 5, bootstrap) together with the need to comply with web-accessibility standards resulted in a gradual move from static, hand-coded sites to other solutions. in 2005, yu stated, “today’s content management solution is either a sophisticated software-based system or a databasedriven application.”17 after a detailed explanation of the cumbersome process of managing and updating a static site using microsoft’s frontpage, kane and hegarty noted, “the opportunity to migrate the site to a content management system provided a golden opportunity . . . to bring the code into line with best practice.”18 this transition also coincided with the growth of viable cms options, particularly open-source tools. black stated in 2011: “in the past few years, the field of open-source cmss has increased, making it more likely that a library will find a viable cms in the existing marketplace that will meet the organization’s needs.”19 in 2013, comeaux and schmetzke replicated an earlier study of library websites’ accessibility, reviewing the homepages of library websites at 56 institutions offering ala-accredited library and information science programs using bobby, an automated web-accessibility checker. they found that cms-powered library websites had a higher average of approved pages and a lower average of errors per page than those not powered by a cms.20 in a 2017 study, comeaux manually reviewed 37 academic library websites (members of the association of southeastern research libraries), and found that approximately three-quarters of cms-driven sites were responsive, as compared to only one-quarter of sites without a cms.21 accessibility also manifests itself on the web in other ways. it is important to consider what we know about literacy and how people read online. the ability to write using plain language, in addition to other essential techniques for effective web writing, is an important aspect of accessibility that must be addressed in tandem with compliance with industry standards such as the web content accessibility guidelines (wcag, https://www.w3.org/tr/wcag20/). a summary of recent results for the program for the international assessment of adult competencies (piaac, https://nces.ed.gov/surveys/piaac/) survey, administered to us adults, reported “the majority of people may struggle to read through a ‘simple’ bullet-point list of rules . . . nearly 62% of our population might not be able to read a graph or calculate the cost of shoes reliably.”22 blakiston succinctly observed: “on the web, scanning and skimming is the default.”23 these trends have led to an increasing push to adopt “plain language” by governmental agencies and others.24 skaggs stated, “adopt plain language throughout your website. plain language focuses on understanding and writing for the user’s goals, making content easily scannable for the user, and writing in easy to understand sentences.”25 library websites and the challenges of a distributed environment in 2011, black pointed out one of the chief advantages to using a cms: “cmss support a distributed content model by separating the content from the presentation and giving the content provider an easy to use interface for adding content”.26 empowerment to focus on special expertise is noted as another benefit: “chief among the efficiencies gained in using a cms is the simple act of giving content authors the tools they need to create webpages and, most importantly, to do so without requiring the technical knowledge that used to be a part of webpage development. designers can design, writers can write, editors can edit, and technology folks can manage the cms and support https://www.w3.org/tr/wcag20/ https://nces.ed.gov/surveys/piaac/ information technology and libraries | september 2019 12 its users.”27 browning and landes agreed: “the concept of ‘self-service authoring’, whereby staff do not need special skills to edit the content for which they are responsible, can be regarded as a major step towards acceptance of the web as a medium for communication by non-web specialists. providing this is the key advantage of a cms.”28 librarians quickly found, however, that while the adoption of a cms could empower more subject matter experts to participate in web content development and address technical issues such as responsive design and compliance with accessibility standards, the transition to a distributed model of content creation, oversight, and maintenance resulted in larger organizational ramifications. in 2006, approximately a decade following libraries’ general move to the web and at an early stage for cms adoption, guenther (2006) cautioned: “a cms is only a tool. purchasing the very best cms with every bell and whistle available will be a useless exercise without a solid plan to guide people and processes around its use.”29 this same article went on to observe: what makes using a cms a tremendous advantage is exactly what makes it a potential nightmare. a cms can make website development really easy; that's the good part. the bad part is, it makes webpage development really easy. one of the first issues you encounter is having to suddenly support a lot more content authors posting a lot more content. what once was an environment with limited activity can become a web development environment requiring considerably more oversight and technical support. having more hands stirring the pot, so to speak, is wrought with all kinds of challenges. 30 untenable growth this model of distributed content creation, in which authorship is undertaken by numerous parties across the organization, generally results in a rapidly increasing quantity of content without necessarily guaranteeing consistent quality. a review of the literature reveals that, more commonly, a distributed model leads to a lack of consistency and focus in library web content’s structure and execution. some papers underscore the problematic quality of the highly individualized nature of the content: “the sheer mass of [libraries’] public web presence has reached the point where maintenance is a problem. often the webpages grew out of the personal interests of staff members, who have since left for other jobs for other responsibilities or simply retired.”31 blakiston stated, “for a number of years, librarians were motivated to create more web content. it was assumed that adding more content was a service for library users, and it was also seen as a way to improve their web skills and demonstrate their fluency with technology.”32 similarly, chapman and demsky described how the university of michigan library website grew “in an organic fashion” and noted, “[a]s in many places, the library’s longstanding attitude toward the web was that more was more and that there was really no harm in letting the website develop however individual units and librarians thought best.”33 other papers described “authority and decision-making issues . . . differing opinions, turf struggles or a lack of communication . . . a shortage of time and motivation, general inertia, and resistance to change on the part of content authors.”34 iglesias noted, “some librarians will always be more comfortable creating webpages from scratch, fearing a loss of control. the library as a whole must decide if the core responsibility of librarians is to create content or to create websites.”35 library-authored web content and the need for content strategy | mcdonald and burkhardt 13 https://doi.org/10.6017/ital.v38i3.11015 newton and riggs stated, “this approach to content appears to be at odds with the role of librarians as leaders in information management practices and in supporting users to find , filter and critically evaluate information.”36 in her article “editorial and technological workflow tools to promote website quality,” morton-owens discussed several studies measuring the severe impact of even small flaws (such as typographical errors) on users’ judgements of a website’s credibility, and, by extension, of the organization’s credibility: “users’ experience of a website leads them to attribute characteristics of competence and trustworthiness to the sponsoring organization.”37 a. paula wilson, citing mcconnell and middleton, summarized the potential pitfalls inherent in a distributed model in which empowerment of content creators overshadows a unified vision, strategy, and approach to library-wide content management: a decentralized model without the use of guidelines, standards or templates will eventually fail. the website may experience inconsistency in presentation and navigation, outdated and incorrect information, and gaps in content, and its webpages maybe noncompliant in usability and accessibility design so much so that users cannot find information.38 inconsistent voice and lack of organizational unity in addition to such compounding factors and in contrast to journalistic practice, “libraries lack an editorial culture where content production and management is viewed as a collective rather than a personal effort.”39 morton-owens noted: “the concept of editing is not yet consistently applied to websites unless the site represents an organization that already relies on editors (like a newspaper)—but it is gaining recognition as a best practice. if the website is the most readily available public face of an institution, it should receive editorial attention just as a brochure or fundraising letter would.”40 in an environment with distributed authorship lacking a strong and consistent editorial culture, an organization's “voice” can quickly deteriorate. in web writing, voice is often defined as personality. blakiston stated: “the written content you provide plays an essential role in defining your library as an organization.”41 young went further, aligning voice with values, and arguing “[a]ny item of content that your library creates—an faq, a policy page, or a facebook post—should be conveyed in the voice of your library and should communicate the values of your library. a combined expression of content and values defines the voice of your organization.” 42 in their 2006 article “cms/cms: content management system/change management strategies,” goodwin et al. insightfully explore organizational challenges: the effort of developing a unified web presence reveals where the organization itself lacks unity . . . effective use of a content management system requires an organized and comprehensive consolidation of library resources, which emphasizes the need for a different organizational model and culture—one that promotes thinking about the library as a whole, sharing and collaboration.43 fulton built on this concept: “disunity in the library’s web interface could signify disunity within the institution. on the other hand, a harmonious web presence suggests an institution that works well together.”44 young drew an inherent connection between a strongly unified organizational identity and a consistent and coherent “content strategy”: information technology and libraries | september 2019 14 while libraries in general can draw on decades or centuries of cultural identity, each individual library may wish to convey a unique set of attributes that are appropriate for unique contexts. in this way, the element of “organizational values” inherent to content strategy signals a larger visioning project for determining the mission, vision, and values of your library. if these elements are already in place, then the work of content strategy can easily be adapted to fit existing values statements. otherwise, content strategy and organizational values can develop as a joint initiative. 45 library websites and content strategy content strategy is an emerging discipline that brings together concepts from user experience design, information architecture, marketing, and technical writing. content strategy encompasses activities related to creating, updating, and managing content that is intentional, useful, usable, well-structure, easily found, and easily understood, all while supporting an organization’s strategic goals.46 browning and lowndes recognized as early as 2002 that strategy would be required as the variety of communication channels for libraries increased: “as local information systems integrate and become more pervasive, self-service authoring extends to the concept of ‘write once, re-use anywhere’, in which the web is treated as just another communication channel along with email, word processor files and presentations, etc.”47 more than a decade later, in the introductory column to a 2013 themed issue of information outlook focused on content strategy, hales stated: content strategy is a field for which information professionals and librarians are ideally suited, by virtue of both their education and temperament. content, after all, is another word for information, and librarians and information professionals have been developing strategies for acquiring, managing, and sharing information for centuries. today, however, information is available to more people in more forms and through more channels than ever before, making content strategies a necessity for organizations rather than an afterthought.48 jones and farrington posited a common refrain for stating the importance of content strategy for librarianship: “library website content must be viewed in much the same way as a physical collection” and the “library website, to apply s. r. ranganathan’s fifth law, is a growing organism and must be treated as such, especially with the complexity of web content.”49 claire rasmussen drew connections between ranganathan’s laws and content strategy in a blog post, pointing out that web content represents an additional set of responsibilities to be managed: “for hundreds of years, librarians have been the primary caretakers of the content corpus. but somebody needs to care for the content that never makes it into a library’s collections, too.”50 blakiston & mayden provided a helpful overview of content strategy and its application in libraries in their article “how we hired a content strategist (and why you should too),” finding many points of connection between skill sets essential to content strategy and those commonly possessed by librarians: librarians who have worked in public services may have the needed skills to ask good questions and find out what users need . . . professionals doing this kind of work came from backgrounds including communications, english and library science . . . desirable library-authored web content and the need for content strategy | mcdonald and burkhardt 15 https://doi.org/10.6017/ital.v38i3.11015 qualifications for . . . content strategist[s] . . . [include] strategic planning, web skills and project management.51 the circumstances that motivated them to propose and eventually hire a dedicated content strategist at the university of arizona libraries hearken back to the discussion earlier in this article regarding the increasing complexity of web librarianship: “the web product manager had independently coordinated all user research and content strategy work. the idea of both managing [a major web redesign project] and leading these other important areas was not realistic.”52 datig also pointed to increasing day-to-day responsibilities when advocating for the importance of content strategy for librarians with outreach and marketing responsibilities: “lack of time, and a desire for that time to be well spent, is a huge concern for all librarians involved in library outreach and marketing . . . content strategy is an important and overlooked aspect of maintaining an effective and vital library outreach program.”53 hackett reflected on her role as web content strategist in a blog post after a recent website migration, noting: “moving forward with a content strategy . . . will ensure that university libraries’ website is useful, usable, and discoverable—now and in the future.”54 yet, while the need for strategy is hard to dispute and librarians are theoretically well suited for web content strategy work, blakiston & mayden noted that explicit organizational support for content strategy in libraries remained limited: “despite the growing popularity of content strategy as a discipline, only a handful of libraries had hired staff dedicated to this role at the time we proposed adding a content strategist to our staff.”55 conclusion this article has traced the history of library adoption of web content management systems, the evolution of those systems, and the corresponding challenges as libraries have attempted to manage increasingly prolific content creation workflows across multiple, divergent cms platforms. what is the library website, anyway? while some variation would to be expected from institution to institution, largely missing from the conversation is agreement on the purpose and aim of the library website writ large. this lack of definition, together with the technological and growth-related issues already discussed, has doubtless contributed to the confusion. after all, how would we know if we are “building it right” if we are not sure what we are meant to be building in the first place? in response to this ambiguity, the following definition was proposed: the library website is an integrated representation of the library, providing continuously updated content and tools to engage with the academic mission of the college/university. it is constructed and maintained for the benefit of the user. value is placed on consump tion of content by the user rather than production of content by staff.56 effective management of library web content requires dedicated resources and clear authority inconsistent processes, disconnects between units, varying constituent goals, and vague or ineffective wcm governance structures are recurrent themes throughout the literature. as cms applications have enabled broader access to web publishing, models of library web management information technology and libraries | september 2019 16 have moved away from workflows structured around strictly technical tasks and permissions, and have instead migrated toward consensus-based, revolving committee structures. while greater involvement of subject matter experts has been noted as a positive earlier in this article, other challenges have also been acknowledged. mcdonald, haines, and cohen stated: “in the context of web design and governance, consensus is a blocker to nimble, standards-based, user-focused action.”57 library website as an integrated representation of the organization as previously discussed, web content governance issues often signal a lack of coordination, or even of unity, across an organization. demsky stated, “we won’t be fully successful until we see it as our website” (emphasis added).58 internal documentation from the university of michigan library emphasized the value of “publicly represent[ing] ourselves as one library,” and stated: the more people are provided with clear communication that shows our offerings and unique items are part of the . . . library—rather than confuse users by making primary attribution to a sub-library, collection, or service point—the more people will recognize and understand the library's tremendous, overall value.59 content strategy and the case for library-authored content no cms can, by itself, address the fact that authoring, editing, and publishing quality content is both a situated expertise and a significant, ongoing demand on staff time. each platform, resource, or database brings its own visual style, terminology, tone and functionality. they are all parts of the library experience, which in turn is one part of the student, research or teaching experience. an understanding of content strategy is critical if staff are to see the connections between their own content and the rest of the content delivered by the organization.60 libraries must proactively embrace and employ best practices in content strategy and in writing for the web to effectively address considerations of literacy and to present a consistent voice for the organization. these practices position libraries to fully realize the promise of content management systems through embracing an ethos of library-authored content. the authors define library-authored content as collectively owned and authored content that represents the organization as a whole. library-authored content is: • collaboratively planned, written, and edited with participation of both subject matter experts and domain experts (i.e., library staff with expertise in content strategy, web librarianship); • carefully drafted to optimize for clarity within the context of the end-user; • current, reviewed on a recurrent schedule, and regularly updated; • consistent across the ecosystem of cms applications and other platforms, including print materials and social media; • compliant with industry standards (including but not limited to those related to accessibility), and with relevant internal brand standards; and • centrally managed as the primary responsibility of one or more domain experts. library-authored web content and the need for content strategy | mcdonald and burkhardt 17 https://doi.org/10.6017/ital.v38i3.11015 in order for libraries to meet the ever-increasing demands on our resources to produce timely, user-centered content that advances our missions for supporting teaching, research, and learning, a cultural shift toward a more collective, collaborative model of web content management and governance is necessary. content strategy provides a flexible, adaptable framework for libraries to more efficiently and effectively leverage the power of multiple cms platforms, to present engaging on-point content, and to provide appropriate, scaffolded support for researchers at all levels — with a team of one or a team of many. endnotes 1 deane barker, “what web content management is (and isn’t),” in web content management

devendra dilip potnis, reynard regenstreifharms, and edwin cortez information technology and libraries | september 2016 43 abstract mobile applications and mobile websites (mamw) represent information systems that are increasingly being developed by libraries to better serve their patrons. because of a lack of in-house it skills and the knowledge necessary to develop mamw, a majority of libraries are forced to rely on external it professionals who may or may not help libraries meet patron needs but instead may deplete libraries’ scarce financial resources. this paper applies a system analysis and design perspective to analyze the experience and advice shared by librarians and it professionals engaged in developing mamw. this paper identifies key steps and precautions to take while developing mamw for libraries. it also advises library and information science graduate programs to equip their students with the specific skills and knowledge needed to develop and implement mamw. introduction the unprecedented adoption and ongoing use of a variety of context-specific mobile technologies by diverse patron populations, the ubiquitous nature of mobile content, and the increasing demand for location-aware library services have forced libraries to “go mobile.” mobile applications and mobile websites (mamw), that is, web portals running on mobile devices, represent information systems that are increasingly being developed and used by libraries to better serve their patrons. however, a majority of libraries often lack the in-house human resources necessary to develop mamw. because of a lack of staff equipped with the requisite it skills and knowledge, libraries are often forced to partner with and rely on external it professionals, potentially losing control over the process of developing mamw.1 partnerships with external it professionals do not always help libraries meet the information needs of their patrons but instead can deplete their scarce financial resources. it then becomes necessary for librarians to understand the process of developing mamw to better evaluate mamw for better serving library patrons. one possibility devendra dilip potnis (dpotnis@utk.edu) is associate professor, school of information sciences; reynard regenstreif-harms (reynardrh@gmail.com) is project archives technician, great smoky mountains national park,

mailto:ecortez@utk.edu identifying key steps for developing mobile applications & mobile websites for libraries | potnis, regenstreif-harms, and cortez |doi:10.6017/ital.v35i2.8652 44 is to re-educate themselves through continuing education or other professional development activities. another solution would be to see library and information science (lis) schools strengthen their curriculum in the area of management, evaluation, and application of mamw and related emerging technologies. issues, challenges, and strategies for providing librarians with these opportunities are abundant and have been debated for more than thirty years, especially since libraries started experiencing the impact of microchip and portable technologies.2 any practical and immediate guidance could help librarians in charge of developing mamw.3 however, a majority of the practical guidance available for developing mamw for libraries is limited to specific settings or patron populations. also, the practical guidance is not theoretically validated, curtailing its generalizability for diverse library settings. for instance, a number of librarians and it professionals share their experience and stories of mamw development to serve a specific patron population in a specific library setting.4,5 their stories typically describe their success stories of developing mamw, the lessons learned during the development of mamw, or their advice for developing mamw. this paper applies a system analysis and design perspective from the information systems discipline to examine the experience and advice shared by librarians and it professionals for identifying the key steps and precautions to be taken when developing mamw for libraries. system analysis and design, a branch of the information systems discipline, is the most widely used theoretical knowledgebase available for developing information systems.6 according to the system analysis and design perspective, development, planning, analysis, design, implementation, and maintenance are the six phases of building any information system.7 the next section synthesizes our method for this secondary research. the following section discusses the key steps we identified for developing, planning, analyzing, designing, implementing, and maintaining mamw for libraries. the concluding section presents the implications of this study for libraries and lis graduate programs. method we began this study with a practitioner’s handbook guiding libraries to use mobile technologies for delivering services to diverse patron populations.8 to search the literature relevant to our research, we devised many key phrases, including but not limited to “mobile technolog*,” “mobile applications for libraries,” and “mobile websites for libraries.” as part of our active informationseeking process, we applied a snowball sampling technique to collect more than seventy-five scholarly research articles, handbooks, ala library technology reports, and books hosted on ebsco and information science source databases. our passive information-seeking was helped by article suggestions from emerald insight and elsevier science direct, two of the most widely used journal hosting sites, in response to the journal articles we accessed there. we applied the following four criteria to establish the relevancy of publications to our research: accuracy of facts; duration of publications (i.e., from 2000 to 2014); credibility of authors; and content focused on information technology and libraries | september 2016 45 problems, solutions, advice, and tips for developing mamw. several research articles published by information technology and libraries and library hi tech, two top-tier journals covering the development of mamw for libraries, built the foundation of this secondary research. we analyzed the collected literature using the qualitative data presentation and analysis method proposed by miles and huberman.9 we developed microsoft excel summary sheets to code the experience and advice shared by librarians and it professionals. the coded data was read repeatedly to identify and name patterns and themes. each relevant publication was analyzed individually and then compared across subjects to identify patterns and common categories. the inter-coder reliability between the two authors who analyzed data was 85 percent. data analysis helped us identify the key steps needed for planning, analyzing, designing, implementing, and maintaining mamw for libraries. findings and discussion key steps for planning mamw forming and managing a team building teams of people with the appropriate skills, knowledge, and experience is one of the first steps suggested by the existing literature for planning mamw. it is essential for team members to be aware of new developments and trends in the market.10 for instance, developers should be aware of print resources on relevant technologies such as apache, asp, javascript, php, ruby on rails, and python, etc.; online resources such as detectmobilebrowser.com and w3c mobileok checker to test catalogs, design functionality, and accessibility on mobile devices; and various online communities of developers who could provide peer-support when needed.11 team members are also expected to keep up with new developments in mobile devices, platforms, operating systems, digital rights management terms and conditions, and emerging standards for content formats.12 periodic delegation of various tasks could help libraries develop mamw effectively.13 libraries should also form productive, financially feasible partnerships with external stakeholders such as internet service providers and network administrators for hosting mamw on appropriate internet servers that meet desired safety and security standards.14,15 requirements gathering requirements for developing mamw can be collected through empirical research and secondary research. typically, the goal of empirical research is to help libraries [set off as bulleted list?]gather patron preferences for and expectations of mamw,16,17 stay abreast of the continual evolution of patron needs,18 periodically (e.g., quarterly, annually, biannually, etc.) gather and evaluate user needs,19 index the content of mamw,20 investigate the acceptance of the library’s use of mamw by patrons,21 understand user needs, and identify top library services requested by patrons. identifying key steps for developing mobile applications & mobile websites for libraries | potnis, regenstreif-harms, and cortez |doi:10.6017/ital.v35i2.8652 46 empirical research in the form of usability testing, functional validation, user surveys, etc., should be carried out before developing mamw to inform the development process and/or after developing mamw to study their adoption by library patrons. empirical research typically involves the identification of patrons and other stakeholders who are going to be affected by mamw. this step is followed by developing data-collection instruments, collecting data from patrons and other stakeholders, and analyzing qualitative and quantitative data using appropriate techniques and software.22 secondary research mainly focuses on scanning and assessing existing literature. for instance, using appropriate datasets on mobile use, librarians may be able to identify the factors responsible for the adoption of mobile technologies.23 typically, such factors include but are not limited to cognitive, affective, social, and economic conditions of potential users. mamw developers could also scan the environment by examining existing mamw and reviewing the literature to create sets of guidelines for replacing old information systems by developing new, well-functioning mamw.24 librarians could also scan the market for free software options to conserve financial resources.25 making strategic choices mobile applications or mobile websites? one of the most important strategic decisions libraries need to make during this phase is whether to use a mobile app or a mobile website—that is, a web portal running on mobile devices—for offering services to patrons. mobile websites are web browser-based applications that might direct mobile users to a different set of content pages, serve a single set of content to all patrons while using different style sheets or templates reformatted for desktop or mobile browsers, or use a site transcoder (a rule-based interpreter), which resides between a website and a web client and intercepts and reformats content in real time for a mobile device.26,27 mobile apps are more challenging to build than mobile websites because they require separate and specific programming for each operating system.28 mobile apps burden users and their devices. for instance, users are expected to remember the functionality of each menu item, and a significant amount of memory is required to store and support apps on mobile devices. however, potential profitability, better mobile-device functionality, and greater exposure through app stores can make mobile apps an economical option over mobile websites.29 buy or build? in the planning phase, libraries also need to decide whether to buy commercial, off-the-shelf (cots) mamw or build a customized mamw. mamw need to be evaluated in terms of customer support and service, maintenance, the ability to meet patron needs, and library needs when making this choice.30 sometimes libraries purchase cots products and end up customizing them, benefiting from both options. for example, some libraries first purchase packaged mobile frameworks to create simple, static mobile websites and subsequently develop dynamic library apps specific to library services.31 information technology and libraries | september 2016 47 managing scope many libraries have limited financial resources, which makes it necessary for their staff to manage the scope of mamw development. the ability to prioritize tasks and identify mission-critical features of mobile mamw are some of the most common activities undertaken by libraries to manage this scope.32 for instance, it is not practical to make entire library websites mobile because libraries would end up serving only those patrons who access their sites over mobile alone. instead, libraries should determine which part of the website should go mobile. a growing trend of using products like mobile first design to design a mobile version of a website first and then work up to a larger desktop version could help librarians better manage the scope of mamw development. alternatively, jeff wisniewski, a leading web services librarian in the united states, advises libraries to create a new mobile-optimized homepage alone, which is faster than trying to retrofit the library’s existing homepage for mobile.33 this advice is highly practical because no webmaster has any interest in trying to maintain two distinct versions of the library’s webpages with details such as hours of operations and contact information. selecting the appropriate software development method there are three key methods for developing mamw: structured methodologies (e.g., waterfall or parallel), rapid application prototyping (e.g., phased, prototyping, or throwaway prototyping), and agile development, an umbrella term used to refer to the collection of agile methodologies like crystal, dynamic systems development method, extreme programming, feature-driven development, and scrum. there is a bidirectional relationship between these mamw development methods and the resources available for their development. project resources such as funding, duration, and human resources influence and are affected by the type of software development method selected for developing mamw. however, studies rarely pay attention to this important dimension of the planning phase.34 key steps in the analysis phase requirements analysis after collecting data from patrons, the next natural step is to analyze the data to inform the process of conceptualizing, building, and developing mamw.35 the requirements-analysis phase helps libraries achieve user-centered design of mamw and assess the return on investment in mamw. the context and goals of the patrons using mobile devices, and the tasks they are likely and unlikely to perform on a mobile device, are the key considerations for developing user-centered mamw for library patrons.36 it is critical to gather, understand, and review user needs.37 surveys can be developed on paper or online, which can be analyzed using advanced statistical techniques or qualitative software.38,39 the analysis allows the following questions to be answered: which identifying key steps for developing mobile applications & mobile websites for libraries | potnis, regenstreif-harms, and cortez |doi:10.6017/ital.v35i2.8652 48 library services do patrons use most frequently on their mobile devices? what is their level of satisfaction for using those services? what types of library services and products would they like to access with their mobile phones in the future? survey analyses can help librarians predict which mobile services patrons will find most useful;40 they can also help librarians classify users on the basis of their perceptions, experience, and habits when using mobile technologies to access library services.41 as a result, libraries can identify and prioritize functional areas for their mamw deployment.42 mamw developers can learn from their users’ humbling and/or frustrating experience of using mobile devices for library services. in addition, libraries can keep track of their patrons’ positive and negative observations, their information-sharing practices, and howthey create group experiences on the platform provided by their libraries.43 to improve existing mamw, libraries could also use google analytics, a free web metrics tool, for identifying the popularity of mamw features and analyzing statistics on how they are used.44 to develop operating system-specific mobile apps, google analytics can be used to learn about the popularity of mobile devices used by patrons.45 ideally, libraries should calculate and document roi before investing in the development of mamw.46 for instance, libraries can run a cost-benefit analysis on the process of developing mamw and compare various library services offered over mobile devices.47 typically the following data could help libraries run the cost-benefit analysis: specific deliverables (e.g., features of mamw), resources (e.g., resources needed, available resources, etc.), risks (e.g., types of risks, level of risks, etc.), performance requirements, and security requirements for developing mamw. this analysis would help libraries make decisions on service provisions such as specific goals to be set for developing mamw, feasibility of introducing desired features of mamw, and how to manage available resources to meet the set goals.48 libraries should also examine what other libraries have already done to provide mobile services.49 communication/liaising with stakeholders the effective communication between developers and stakeholders influences almost every aspect of developing information systems. however, existing studies do not emphasize the significance of communication with stakeholders. for instance, several studies vaguely refer to the translation of user needs into technology requirements.50 but few studies point out the precise modeling technique (e.g., entity relationship diagrams, unified modeling language, etc.) for converting user needs into a language understood by software developers. developers should communicate best practices and suggestions for the future implementation of mamw in libraries,51 which involves the prediction and selection of appropriate mamw for libraries,52 the demonstration of what is possible and how services are relevant, and how new resources can help create value for libraries.53,54 communication with users is also critical for creating value-added services for patrons who use different mobile technologies to meet their needs related to work, leisure, commuting, etc.55 information technology and libraries | september 2016 49 however, the existing literature on mamw development for libraries does not mention the significance of this activity. key steps for designing mamw prototyping prototyping refers to the modeling or simulation of an actual information system. mamw can have paper-based or computer-based prototypes. prototyping allows developers to directly communicate with mamw users to seek their feedback. developers can correct or modify the original design of mamw until users and developers are in agreement about the system design. building consensus between mamw developers and potential users is another key challenge to overcome during this phase, which may put a financial burden on mamw development projects. it requires skilled personnel to manage the scope, time, human resources, and budget of such projects. wireframing is one of the most prominent prototyping techniques practiced by librarians and it professionals for developing mamw for libraries.56 this technique depicts schematic on-screen blueprints of mamw, lacking style, color, or graphics, focusing mainly on functionality, behavior, and priority of content. selecting hardware, programming languages, platforms, frameworks, and toolkits existing literature on the development of mamw for libraries covers the selection and management of software; software development kits; scripting languages like javascript; data management and representation languages such as html, xml, and their text editors; and ajax for animations and transitions. the existing literature also guides libraries for training their staff for using mamw to better serve patrons.57 few studies also provide guidance on selecting cots products such as webkit, an open source web browser engine that renders webpages on smartphones and allows users to view high-quality graphics on data networks with faster throughput.58 however, it might be a good idea to use licensed open source cots products because licensed software allows libraries to legally distribute software within their organizations as covered by the licensing agreement. libraries that use software-licensing agreements may also be able to seek expert help and advice whenever they have a concern or query. in the authors’ experience, librarians have shared few effective strategies to design mamw. one key strategy is to purchase reliable device emulators and cross-compatible web editors. these technologies allow the user to work with the design at the most basic level, save documents as text, transfer the documents between web programs, and direct designers toward simple solutions.59 sample cross-compatible web editors include, but are not limited to, notetab pro (http://www.notetab.com/), code lobster (http://www.codelobster.com/), and bluefish (http://bluefish.openoffice.nl). http://www.notetab.com/ http://www.codelobster.com/ http://bluefish.openoffice.nl/ identifying key steps for developing mobile applications & mobile websites for libraries | potnis, regenstreif-harms, and cortez |doi:10.6017/ital.v35i2.8652 50 hybrid mobile app frameworks like bootstrap, ionic, mobile angular ui, intel xdk, appcelerator titanium, sencha, kendo ui, and phonegap use a combination of web technologies like html, css, and javascript for developing mobile-first, responsive mamw. a majority of these frameworks use a drag-and-drop approach and do not require any coding for developing mobile apps. one-click api connect further simplifies the process. user-interface frameworks like jquerymobile and topcoat eliminate the need to design user interfaces manually. importantly, mamw developed using such frameworks can support many mobile platforms and devices. toolkits like github, skyronic, crudkit, and hawhaw enable developers to quickly build mobilefriendly crud (create/read/update/delete) interfaces for php, laravel, and codeigniter apps. such mobile apps also work with mysql and other databases, allowing users to receive and process data and display information to users. table 1 categorizes specific hardware and

what resources are used and who used them88 integrate a geo-location feature with mobile services89 table 1. mamw with specific hardware and software features from the above table, which is based on the analysis of the literature on developing mobile applications and mobile websites for libraries, it becomes clear that web programming and hci are the two leading technology areas that shape the development of mamw and consequently the services offered by them. designing user interfaces of mamw librarians and it professionals engaged in developing mamw for libraries make the following recommendations. use two style sheets: css play a key role in offering uniform display to user interfaces for all webpages. studies recommend designing two style sheets—namely, mobile.css and iphone.css— when developing mamw, since most of the time smartphones ignore mobile stylesheets.90 in that case, iphone.css could direct itself to browsers of a specific screen-width, helping those mobile devices that are not directed to the mobile website by the mobile.css stylesheet.91 minimize use of javascript: javascript is instrumental in detecting what mobile device is being used by patrons and then directing them to the appropriate webpage with options including full website, simple text-based, and touch-mobile-optimized. however, it is critical to minimize the use of javascript on library mobile websites because not every smartphone offers the minimum level of support required to operate it.92 handle images intelligently: to help patrons optimize their bandwidth use, image files on mobile sites should be incorporated with css rather than html code; also, to ensure consistency in the information technology and libraries | september 2016 53 appearance of user interfaces of mobile websites, images should be kept to the same absolute size.93 key steps for implementing mamw programming for mamw programming is at the heart of developing mamw. as shown in table 1 above, web programming enables developers to build mamw with a number of value-added features for patrons. for instance, a web-application server running on cold fusion can process data communicated via web browsers on mobile devices; this feature allows mamw users to access search engines on library websites via smartphones.94 also, client-side processing of classes (with a widget library) allows patrons to use their mobile devices as thin clients, thereby optimizing the use of network bandwidth.95 testing mamw past studies recommend testing the content, display/design, and functionality of mamw in a controlled environment (e.g., usability lab) or in the real world (i.e., in libraries). content: librarians are advised to set up testing databases for testing image presentation, traditional free text search, location-based search, barcode scanning for isbn search, qr encapsulation, and voice search.96 display/design: librarians can review and test mamw on multiple devices to confirm that everything displays and functions as intended.97 they can also test a beta version of their mobile website with varying devices to provide guidance regarding image sizing;98 beta versions are also useful in testing mobile websites for their display on different browsers and devices.99 functionality: librarians can set up testing practices and environments for the most heavily used device platforms (e.g., hci incubators such as eye testing software, which is a combination of virtual emulators and mobile devices not owned by libraries).100,101 they can also use the user agent switcher add-on for firefox to test a mobile website and use web-based services like device anywhere and browser cam offering mobile emulation to test the functionality of mamw.102 training patrons unless patrons realize the significance of a new information system for managing information resources they will hardly use it. however, training patrons for using a newly developed mamw is almost completely missing from the studies describing the process of developing mamw for libraries. joe murphy, a technology librarian at yale university, identifies the significance of user training in managing the change from traditional to mobile search and advises librarians to explore the mobile literacy skills of their patrons and educate them on how to use new systems.103 identifying key steps for developing mobile applications & mobile websites for libraries | potnis, regenstreif-harms, and cortez |doi:10.6017/ital.v35i2.8652 54 data management mamw cannot function properly without clean data. cleaning up data, curating data, and addressing other data-related issues are some of the least mentioned activities in the literature for developing mamw. however, it is necessary for librarians engaged in developing mamw to identify and address common challenges for managing data when used for mamw. for example, it might be a good strategy for librarians to study the best practices for managing data-related issues when offering reference services using sms .104 skills needed for maintaining mamw documentation and version control of software past studies recommend developing a mobile strategy for building a mobile-tracking device and evaluating mobile infrastructure to ensure the continued assessment and monitoring of mobile usage and trends among patrons.105 however, past studies do not report or provide many details about the maintenance of mamw, which leads us to infer that maintenance of mamw involving documentation and version control is a neglected aspect of their development. open source software development is increasingly becoming a common practice for developing mamw. implementing version-control software (e.g., subversion and github) to accommodate the needs of developers distributed across the world is a necessity for developing mamw. versioncontrol software provides a code repository with a centralized database for developers to share their code, which minimizes errors associated with overwriting or reverting code changes and maximizes software development collaboration efforts.106 conclusion there are various forces driving change in the knowledge and skills area for information professionals: technologies, changing environments, and the changing role of it in managing and providing services to patrons. these forces affect all levels of it-based professionals, those responsible for information processing and those responsible for information services. this paper has examined the key steps and precautions to be taken while developing mamw to better serve their patrons. after analyzing the existing guidance offered by librarians and it professionals from the system analysis and design perspective, we find that some of the most ignored activities in mamw development are selecting appropriate software development methodologies, prototyping, communicating with stakeholders, software version control, data management, and training patrons to use newly developed or revamped mamw. the lack of attention to these activities could hinder libraries’ ability to better serve patrons using mamw. it is necessary for librarians and it professionals to pay close attention to the above activities when developing mamw. information technology and libraries | september 2016 55 our study also shows that web programming and hci are the two most widely used technology areas for developing mamw for libraries. to save their scarce financial resources, which otherwise could be invested in partnering with external it professionals, libraries could either train their existing staff or recruit lis graduates equipped with the skills and knowledge identified in this paper to develop mamw (see table 2). #

skills and knowledge necessary to develop mamw the management of scope, time, cost, quality, human resources, and communication related to any project is known as project management.107 in addition to the skills and knowledge related to project management, librarians would also need to be proficient in software development (with an emphasis on hci and web programming), data management, and the proper methods for conducting empirical and secondary research for developing mamw. if lis programs equip their graduate students with the skills and knowledge identified in this paper, the next generation of lis graduates could develop mamw for libraries without relying on external it professionals, which would make libraries more self-reliant and better able to manage their financial resources.108 this paper assumes a very small number of scholarly publications to be reflective of the realworld scenarios of developing mamw for all types of libraries. this assumption is one of the limitations of this study. also, the sample of publications analyzed in this study is not statistically representative of the development of mamw for libraries around the world. in the future, the authors plan to interview librarians and it professionals engaged in developing and maintaining mamw for their libraries to better understand the landscape of developing mamw for libraries. references

 technology  and  libraries  |  march  2015             38   abstract   one  hundred  fifteen  academic  libraries,  all  current  members  of  the  association  of  research  libraries   (arl),  were  selected  to  participate  in  an  online  survey  in  an  effort  to  better  understand  campus   usage  of  geographic  data  and  geospatial  technologies,  and  how  libraries  support  these  uses.  the   survey  was  used  to  capture  information  regarding  geographic  needs  of  their  respective  campuses,  the   array  of  services  they  offer,  and  the  education  and  training  of  geographic  information  services   department  staff  members.  the  survey  results,  along  with  review  of  recent  literature,  were  used  to   identify  changes  in  geographic  information  services  and  support  since  1997,  when  a  similar  survey   was  conducted  by  arl.  this  new  study  has  enabled  recommendations  to  be  made  for  building  a   successful  geographic  information  service  center  within  the  campus  library  that  offers  a  robust  and   comprehensive  service  and  support  model  for  all  geographic  information  usage  on  campus.   introduction   in  june  1992,  the  arl  in  partnership  with  esri  (environmental  systems  research  institute)   launched  the  gis  (geographic  information  systems)  literacy  project.  this  project  sought  to   “introduce,  educate,  and  equip  librarians  with  the  skills  necessary”  to  become  effective  gis  users   and  to  learn  how  to  provide  patrons  with  “access  to  spatially  referenced  data  in  all  formats.”1   through  the  implementation  of  a  gis  program,  libraries  can  provide  “a  means  to  have  the   increasing  amount  of  digital  geographic  data  become  a  more  useful  product  for  the  typical   patron.”2     in  1997,  five  years  after  the  gis  literacy  project  began,  a  survey  was  conducted  to  elucidate  how   arl  libraries  support  patron  gis  needs.  the  survey  was  distributed  to  121  arl  members  for  the   purpose  of  gathering  information  about  gis  services,  staffing,  equipment,  software,  data,  and   support  these  libraries  offered  to  their  patrons.  seventy-­‐two  institutions  returned  the  survey,  a  60%   response  rate.  at  that  time,  nearly  three-­‐quarters  (74%)  of  the  respondents  affirmed  that  their   library  administered  some  level  of  gis  services.3  this  indicates  that  the  gis  literacy  project  had  an   evident  positive  impact  on  the  establishment  of  gis  services  in  arl  member  libraries.   since  then,  it  has  been  recognized  that  the  rapid  growth  of  digital  technologies  has  had  a   tremendous  effect  on  gis  services  in  libraries.4  we  acknowledge  the  importance  of  assessing     ann  l.  holstein  (ann.holstein@case.edu)  is  gis  librarian  at  kelvin  smith  library,

 research  libraries  have  further  evolved  over  the  past  17   years  in  response  to  these  advancing  technologies  as  well  as  the  increasingly  demanding   geographic  information  needs  of  their  user  communities.     method   for  this  study,  115  academic  libraries,  all  current  members  of  arl  as  of  january  2014,  were   invited  to  participate  in  an  online  survey  in  an  effort  to  better  understand  campus  usage  of   geographic  data  and  geospatial  technologies  and  how  libraries  support  these  uses.  similar  in   nature  to  the  1997  arl  survey,  the  2014  survey  was  designed  to  capture  information  regarding   geographic  needs  of  their  respective  campuses,  the  array  of  services,  software.  and  support  the   academic  libraries  offer,  and  the  education  and  training  of  geographic  information  services   department  staff  members.  our  aim  was  to  be  able  to  determine  the  range  of  support  patrons  can   anticipate  at  these  libraries  and  ascertain  changes  in  gis  library  services  since  the  1997  survey.   a  cross-­‐sectional  survey  was  designed  and  administered  using  qualtrics,  an  online  survey  tool.  it   was  distributed  in  january  2014  via  email  to  the  person  identified  as  the  subject  specialist  for   mapping  and/or  geographic  information  at  each  arl  member  academic  library.  when  the  survey   closed  after  two  weeks,  54  institutions  had  responded  to  the  survey.  this  accounts  for  47%   participation.  responding  institutions  are  listed  in  the  appendix.   results   software  and  technologies   we  were  interested  in  learning  about  what  types  of  geographic  information  software  and   technologies  are  currently  being  offered  at  academic  research  libraries.  results  show  that  100%  of   survey  respondents  offer  gis  software/mapping  technologies  at  their  libraries,  36%  offer  remote   sensing  software  (to  process  and  analyze  remotely  sensed  data  such  as  aerial  photography  and   satellite  imagery),  and  36%  offer  global  positioning  system  (gps)  equipment  and/or  software.   nearly  all  (98%)  said  that  their  libraries  provide  esri  arcgis  software,  with  83%  also  providing   access  to  google  maps  and  google  earth,  and  35%  providing  qgis  (previously  known  as  quantum   gis).  smatterings  of  other  gis,  remote-­‐sensing,  and  gps  products  are  also  offered  by  some  of  the   libraries,  although  not  in  large  numbers  (see  table  1  for  full  listing).     the  fact  that  nearly  all  survey  respondents  offer  arcgis  software  at  their  libraries  comes  as  no   surprise.  arcgis  is  the  most  commonly  provided  mapping  software  available  in  academic  libraries,   and  in  2011,  it  was  determined  that  2,500  academic  libraries  were  using  esri  products.5  esri   software  was  most  popular  in  1997  as  well,  undoubtedly  because  they  offered  free  software  and   training  to  participants  of  the  gis  literacy  project.6

 google  earth,  launched  in  2005,  have  quickly  become  very  popular  mapping   products  used  at  academic  libraries—a  close  second  only  to  esri  arcgis.  in  addition  to  being  free,   their  ease  of  use,  powerful  visualization  capabilities,  “customizable  map  features  and  dynamic   presentation  tools”  make  them  attractive  alternatives  to  commercial  gis  software  products.7     since  1997,  many  software  programs  have  fallen  out  of  favor.  mapinfo,  idrisi,  maptitude,  and   sammamish  data  finder/geosight  pro  were  gis  software  programs  listed  in  the  1997  survey   results  that  are  not  used  today  at  arl  member  academic  libraries.8  instead,  open  source  software   such  as  qgis,  grass,  and  geoda  are  growing  in  popularity.  they  are  free  to  use  and  their  source   code  may  be  modified  as  needed.   gps  equipment  lending  can  be  very  beneficial  to  students  and  campus  researchers  who  need  to   collect  their  own  field  research  locational  data.  the  2014  survey  found  that  30%  of  respondents   loan  recreational  gps  equipment  at  their  libraries  and  10%  loan  mapping-­‐grade  gps  equipment.   the  high  cost  of  mapping-­‐grade  gps  equipment  (several  thousand  dollars)  may  be  a  barrier  for   some  libraries;  however,  this  is  the  type  of  equipment  recommended  in  best-­‐practice  methods  for   gathering  highly  accurate  gps  data  for  research.  in  addition  to  expense,  complexity  of  operation  is   another  consideration.  while  it  is  “fairly  simple  to  use  a  recreational  gps  unit,”  a  certain  level  of   advanced  training  is  required  for  operating  mapping-­‐grade  gps  equipment.9  a  designated  staff   member  may  need  to  take  on  the  responsibility  of  becoming  the  in-­‐house  gps  expert  and  routinely   offer  training  sessions  to  those  interested  in  borrowing  mapping-­‐grade  gps  equipment.     location     geographic  information  and  technologies  in  academic  research  libraries  |  holstein   41   at  36%  of  responding  libraries,  the  geographic  information  services  area  is  located  where  the   paper  maps  are  (map  department/services);  19%  have  separated  this  area  and  designated  it  as  a   geospatial  data  center,  gis,  or  data  services  department;  13%  integrate  it  with  the  reference   department;  and  just  4%  of  libraries  house  the  gis  area  in  government  documents.  table  2  lists  all   reported  locations  for  this  service  area.  not  surprisingly,  in  1997,  government  documents  (39%)   was  just  as  popular  a  location  for  this  service  area  as  within  the  map  department  (43%).10   libraries  identified  government  documents  as  a  natural  fit,  keeping  gis  services  within  close   proximity  to  spatial  data  sets  recently  being  distributed  by  government  agencies,  most  notably  the   us  government  printing  office  (gpo).  these  agencies  had  made  the  decision  to  distribute  “most   data  in  machine  readable  form,”11  including  the  1990  census  data  as  topographically  integrated   geographic  encoding  and  referencing  (tiger)  files.12  gis  technologies  were  needed  to  access  and   most

 libraries,  geographic  information  software  is  available  on  computer   workstations  in  a  designated  area,  such  as  within  the  map  department.  however,  many  do  not   restrict  users  by  location  and  have  the  software  available  on  all  computer  workstations   throughout  the  library  (37%)  or  on  designated  workstations  distributed  throughout  the  library   (33%).  a  small  percentage  (7%)  loan  laptops  to  patrons  with  the  software  installed,  allowing  full   mobility  throughout  the  entire  library  space.   staffing   most  professional  staff  working  in  the  geographic  information  services  department  hold  one  or   more  postbaccalaureate  advanced  degrees.  of  113  geographic  services  staff  at  responding   libraries,  65%  had  obtained  an  ma/ms,  mls/mlis,  or  phd;  43%  have  one  advanced  degree,  while   22%  have  two  postbaccalaureate  degrees.  half  (50%)  hold  an  mls/mlis,  31%  hold  an  ma/ms,   and  6%  hold  a  phd.  nearly  one-­‐third  (31%)  have  obtained  a  ba/bs  as  their  highest  educational   degree,  3%  had  a  two-­‐year  technical  degree,  and  2%  had  only  earned  a  ged  or  high  school   diploma.  in  1997,  84%  of  gis  librarians  and  specialists  at  arl  libraries  had  an  mls  degree.13  at   that  time,  the  incumbent  was  most  often  recruited  from

 services  staff  (2014)   on  average,  this  department  is  staffed  by  two  professional  staff  members  and  three  student  staff.   student  employees  can  be  a  terrific  asset,  especially  if  they  have  been  previously  trained  in  gis.   students  are  likely  to  be  recruited  from  departments  that  are  the  heaviest  gis  users  at  the   university  (i.e.,  geography,  geology).  some  libraries  have  implemented  “co-­‐op”  programs  where   students  can  receive  credit  for  working  at  the  gis  services  area.  these  dual-­‐benefit  positions  are   quite  lucrative  to  students.14     campus  users   in  a  typical  week  during  the  course  of  a  semester,  responding  libraries  each  serve  approximately   sixteen  gis  users,  four  remote  sensing  users,  and  three  gps  users.  these  users  may  obtain   assistance  from  department  staff  either  in-­‐person  or  remotely  via  phone  or  email.     on  average,  undergraduate  and  graduate  students  compose  the  majority  (75%)  of  geographic   service  users  (32%  and  43%,  respectively).  faculty  members  compose  14%  of  the  users,  followed   by  staff  (including  postdoctoral  researchers)  at  7%.  some  institutions  also  provide  support  to   public  patrons  and  alumni  (4%  and  1%,  respectively).  in  1997,  it  was  estimated  that  on  average,   63%  of  gis  users  were  students,  22%  were  faculty,  8%  were  staff,  and  8%  were  public.15   ged/hs   2%   2yr  tech   3%   ba/bs   31%   ma/ms/mlis   58%   phd   6%

 with  the  departments  of   environmental  science/studies,  geography,  biology/ecology  and  archaeology  (see  table  3  for  full   listing).  some  departments  are  heavy  users  of  all  geographic  technologies,  while  others  have   shown  interest  in  only  one.  for  example,  the  departments  of  psychology  and  medicine/dentistry   have  used  gis  but  have  expressed  little  or  no  interest  in  using  remote-­‐sensing  or  gps  technologies.   support  and  services   the  campus  community  is  supported  by  library  staff  in  a  variety  of  ways  with  regards  to  gis,   remote-­‐sensing,  and  gps  technology  and  software  use.  nearly  all  (94%)  libraries  provide   assistance  using  the  software  for  specific  class  assignments  and  projects,  and  78%  are  able  to   provide  more  in-­‐depth  research  project  consultations.  more  than  one-­‐quarter  (27%)  of  reporting   libraries  will  make  custom  gis  maps  for  patrons,  although  there  may  be  a  charge  depending  on  the   library,  project,  and  patron  type  (10%).  most  (90%)  offer  basic  use  and  troubleshooting  support;   however,  just  39%  offer  support  for  software  installation,  and  55%  offer  technical  support  for   problems  such  as  licensing  issues  and  turning  on  extensions.  the  campus  computing  center  or   information  technology  services  (its)  at  arl  institutions  most  likely  fields  some  of  the  software   installation  and  technical  issues  rather  than  the  library,  thus  accounting  for  the  lower  percentages.     a  variety  of  software  training  may  be  offered  to  the  campus  community  through  the  library;  80%   of  responding  libraries  make  visits  to  classes  to  give  presentations  and  training  sessions,  69%  host   workshops,  47%  provide  opportunities  for  virtual  training  courses  and  tutorials,  and  4%  offer   certificate  training

 of  gis,  remote-­‐sensing,  or  gps   software  and  technologies  from  a  campus  department  (2014)     often,  the  library  is  not  the  only  place  people  can  go  to  obtain  software  support  and  training  on   campus.  most  (86%)  responding  libraries  state  that  their  university  offers  credit  courses,  and  41%   of  campuses  have  a  gis  computer  lab  located  elsewhere  on  campus  that  may  be  utilized.  its  is   available  for  assistance  at  29%  of  the  universities,  and  continuing  education  offers  some  level  of   training  and  support  at  14%  of  campuses.     data  collection  and  access   most  (85%)  of  responding  libraries  collect  geographic  data  and  allow  an  annual  budget  for  it.   “libraries  that  have  invested  money  in  proprietary  software  and  trained  staff  members  will  tend   to  also  develop  and  maintain  their  own  collection  of  data  resources.”16  of  those  collecting  data,  26%   spend  less  than  $1,000  annually,  15%  spend  between  $1,000  and  $2,499,  17%  spend  between   $2,500  and  $5,000,  while  41%  spend  more  than  $5,000.  in  1997,  79%  of  libraries  spent  less  than   $2,000  annually,  and  only  9%  spent  more  than  $5,000.17       geographic  information  and  technologies  in  academic  research  libraries  |  holstein   45     figure  3.  annual  budget  allocations  for  geographic  data  (2014)   a  dramatic  shift  has  occurred  over  the  years  with  budget  allocations  for  data  sets.  no  longer  are   academic  libraries  just  collecting  free  government  data  sets  as  was  typically  the  case  back  in  1997,   but  they  are  investing  much  more  of  their  materials  budget  into  building  up  the  geographic  data   collection  for  their  users.     data  is  made  accessible  to  campus  users  in  a  variety  of  ways.  a  majority  (84%)  offer  data  via   remote  access  or  download  from  a  networked  campus  computer,  using  a  virtual  private  network   (vpn)  or  login.  more  than  half  (62%)  of  responding  libraries  provide  access  to  data  from   workstations  within  the  library,  and  64%  lend  cd-­‐roms.   roughly  one-­‐quarter  (26%)  of  responding  libraries  provide  users  with  storage  for  their  data.  of   those,  29%  have  a  dedicated  geographic  data  server,  14%  use  the  main  library  server,  29%  point   users  to  the  university  server  or  institutional  repository,  and  36%  allow  users  to  store  their  data   directly  onto  a  library  computer  workstation  hard  drive.   internal  use  of  gis  in  libraries   geographic  information  technologies  may  be  used  internally  to  help  patrons  navigate  the  library’s   physical  collections  and  efficiently  locate  print  materials.  of  the  survey  respondents,  60%  use  gis   for  map  or  air  photo  indexing,  27%  use  the  technology  to  create  floor  maps  of  the  library  building,   and  15%  use  it  to  map  the  library’s  physical  collections.  “the  use  of  gis  in  mapping  library   collections  is  one  of  the  non-­‐traditional  but  useful  applications  of  gis.”18  gis  can  be  used  to  link   library  materials  to  simulated  views  of  floor  maps  through  location  codes.19  this  enables  patrons   to  determine  the  exact  location  of  library  material  by  providing  them  with  item  “location  details   such  as  stacks,  row,  rack,  shelf  numbers,  etc.”20  the  gis  system  can  become  a  useful  tool  for   collection  management  and  can  be  a  tremendous  time-­‐saver  for  patrons,  especially  those   unfamiliar  with  the  cataloging  system  or  collection  layout.     discussion   recommendations  for  building  a  successful  geographic  information  service  center   0   5   10   15   20   25   30   35   40   45   percent  (%)     information  technology  and  libraries  |  march  2015   46   the  geographic  information  services  area  is  often  a  blend  of  the  traditional  and  modern.  it  can   extend  to  paper  maps,  atlases,  gps  equipment,  software  manuals,  large-­‐format  scanners,  printers,   and  gis.  gis  services  may  include  a  cluster  of  computers  with  gis  software  installed,  an  accessible   collection  of  gis  data  resources,  and  assistance  available  from  the  library  staff.  the  question  for   academic  libraries  today  is  no  longer  “whether  to  offer  gis  services  but  what  level  of  service  to   offer.”21  every  university  has  different  gis  needs,  and  the  library  must  decide  how  it  can  best   support  these  needs.  there  is  no  set  formula  for  building  a  geographic  information  service  center   because  each  institution  “has  a  different  service  mission  and  user  base.”22  every  library’s  gis   service  program  will  be  designed  with  its  unique  institutional  needs  in  mind;  however,  they  each   will  incorporate  some  combination  of  hardware,  software,  data,  and  training  opportunities   provided  by  at  least  one  knowledgeable  staff  member.23     “gis  represents  a  significant  investment  in  hardware,  software,  staffing,  data  acquisition,  and   ongoing  staff  development.  either  new  money  or  significant  reallocation  is  required.”24   establishing  new  or  enhancing  gis  services  in  the  library  requires  the  “serious  assessment  of  long-­‐ term  support  and  funding  needs.”25  commitment  of  the  university  as  a  whole,  or  at  least  support   from  senior  administration,  “library  administration,  and  related  campus  departments”  is  crucial  to   its  success.26  receiving  “more  funding  will  mean  more  staff,  better  trained  staff,  a  more  in-­‐depth   collection,  better  hardware  and  software,  and  the  ability  to  offer  multiple  types  of  gis  services.”27     once  funding  for  this  endeavor  has  been  secured,  it  is  of  utmost  importance  to  recruit  a  gis   professional  to  manage  the  geographic  information  service  center.  to  be  most  effective  in  this   position,  the  incumbent  should  possess  a  graduate  degree  in  gis  or  geography;  however,   depending  on  what  additional  responsibilities  would  be  required  of  the  candidate  (i.e.,  reference,   cataloging,  etc.)  a  second  degree  in  library  science  is  strongly  recommended.  this  staff  member   should  possess  mapping  and  gis  skills,  which  include  experience  with  esri  software  and  remote   sensing  technologies.  employees  in  this  position  may  be  given  a  job  titles  such  as  “gis  specialists,   gis/data  librarians,  gis/map  librarians,  digital  cartographers,  spatial  data  specialists,  and  gis   coordinators.”28     with  the  new  staff  member  on  board,  hereafter  referred  to  as  “gis  specialist,”  decisions  such  as   what  software  to  provide,  which  data  sets  to  collect,  and  what  types  of  training  and  support  to   offer  to  the  campus  can  be  made.  consulting  with  research  centers  and  academic  departments  that   currently  use  or  are  interested  in  using  gis  and  remote  sensing  technologies  is  a  good  place  to   learn  about  software,  data,  and  training  needs  and  to  determine  the  focus  and  direction  of  the   geographic  information  services  department.29  campus  users  often  come  from  academic   departments  that  “have  neither  staff  nor  facilities  to  support  gis,”  and  “may  only  consist  of  one  or   two  faculty  and  a  few  graduate  students.  these  gis  users  need  access  to  software,  data,  and   expertise  from  a  centralized,  accessible  source  of  research  assistance,  such  as  the  library.”30     at  minimum,  esri  arcgis,  google  maps  and  google  earth  should  be  supported,  with  additional   remote  sensing  or  open  source  gis  software  depending  on  staff  expertise  and  known  campus     geographic  information  and  technologies  in  academic  research  libraries  |  holstein   47   needs.  when  purchasing  commercial  software  licenses,  such  as  for  esri  arcgis,  discounts  for   educational  institutions  are  usually  available.  additionally,  negotiating  campus-­‐wide  software   licenses  may  be  a  good  option  to  consider  as  the  costs  are  usually  far  less  than  purchasing   individual  or  floating  licenses.  costs  for  campus-­‐wide  licensing  are  typically  determined  by  full-­‐ time  equivalent  (fte)  students  enrolled  at  the  university.     facilitating  “access  to  educational  resources  such  as  software  tools  and  applications,  how-­‐to-­‐ guides  for  data  and  software,”  and  tutorials  is  crucial.31  the  gis  specialist  must  be  familiar  with   how  gis  software  can  be  used  by  many  disciplines,  the  availability  of  “training  courses  or  tutorials,   sources  or  extensible  gis  software,  and  hundreds  of  software  and  application  books.”32  tutorials   may  be  provided  direct  from  a  software  vendor  (i.e.,  esri  virtual  campus)  or  developed  in-­‐house   by  the  gis  specialist.  creating  “gis  tutorials  on  short,  task-­‐based  techniques  such  as   georeferencing  or  geocoding”  and  making  them  readily  available  online  or  as  a  handout  may  save   time  having  to  repeatedly  explain  these  techniques  to  patrons.33   geospatial  data  collection  development  is  a  core  function  of  the  geographic  information  services   department.  to  effectively  develop  the  data  collection,  the  gis  specialist  must  fully  comprehend   the  needs  of  the  user  community  as  well  as  possess  a  “fundamental  understanding  of  the  nature   and  use  of  gis  data.”34  this  is  often  referred  to  as  “spatial  literacy.”35  it  is  crucial  to  keep  abreast  of   “recent  developments,  applications,  and  data  sets.”36   the  gis  specialist  will  spend  much  more  time  searching  for  and  acquiring  geographic  data  sets   than  selecting  and  purchasing  traditional  print  items  such  as  maps,  monographs,  and  journals  for   the  collection.  a  budget  should  be  established  annually  for  the  purchase  of  all  geographic   materials,  both  print  and  digital.  a  great  challenge  for  the  specialist  is  to  acquire  data  at  the  lowest   cost  possible.  while  a  plethora  of  free  data  is  available  online  from  government  agencies  and   nonprofit  organizations,  other  data,  available  only  from  private  companies,  may  be  quite   expensive  because  of  the  high  production  costs.  a  collection  development  policy  should  be  created   that  indicates  the  types  of  materials  and  data  collected  and  specifies  geographic  regions,  formats,   and  preferred  scales.37  the  needs  of  the  user  community  must  be  carefully  considered  when   establishing  the  policy.     the  expertise  of  the  gis  specialist  is  needed  not  only  to  help  patrons  locate  the  appropriate   geographic  data,  but  also  to  use  the  software  to  process,  interpret,  and  analyze  it.  “only  the  few   library  patrons  that  have  had  gis  experience  are  likely  to  obtain  any  level  of  success  without   intervention  by  library  staff”;38  thus,  for  any  mapping  program  installed  on  a  library  computer,   “staff  must  have  working  knowledge  of  the  program”  and  must  be  able  to  provide  support  to   users.39  furthermore,  the  gis  specialist  must  be  able  to  train  patrons  to  use  the  software  to   complete  common  tasks  such  as  file  format  conversion,  data  projection,  data  manipulation,  and   geoprocessing.  these  geospatial  technologies  involve  a  steep  learning  curve,  and  unfortunately   “hands-­‐on  training  options  outside  the  university  are  often  cost-­‐prohibitive”  for  many.40  the   campus  community  requires  training  opportunities  to  be  both  convenient  and  inexpensive.     information  technology  and  libraries  |  march  2015   48   teaching  hands-­‐on  geospatial  technology  workshops,  from  basic  to  the  advanced,  is  fundamental   to  educating  the  campus  community.  workshops  will  “vary  from  institution  to  institution,  with   some  offering  students  an  introduction  to  mapping  and  others  focusing  on  specific  features  of  the   program,  such  as  georeferencing,  geocoding,  and  spatial  analysis.  some  also  offer  workshops  that   are  theme  specific,”  such  as  “working  with  census  data”  or  “digital  elevation  modeling.”41  custom   workshops  or  training  sessions  can  be  developed  to  meet  a  specific  campus  need,  tailored  for  a   specific  class  in  consult  with  an  instructor,  or  designed  especially  for  other  library  staff.     today’s  geographic  information  service  center   the  academic  map  librarian  from  the  1970s  or  1980s  would  hardly  recognize  todays’  geographic   information  service  center.  what  was  once  a  room  of  map  cases  and  shelves  of  atlases  and   gazetteers  is  now  a  bustling  geospatial  center.  computers,  powerful  gis  and  remote-­‐sensing   technologies,  gps  devices,  digital  maps,  and  data  are  now  available  to  library  patrons.  every   library  surveyed  provides  gis  software  to  campus  users,  and  85%  also  actively  collect  gis  and   remotely  sensed  data.  with  the  assistance  of  expertly  trained  library  staff,  users  with  no  or  limited   experience  using  geospatial  technologies  are  enabled  to  analyze  spatial  data  sets  and  create   custom  maps  for  coursework,  projects,  and  research.  nearly  all  surveyed  libraries  (94%)  have   staff  that  can  assist  students  specifically  with  software  use  for  class  assignments  and  projects,   while  90%  provide  assistance  with  more  generalized  use  of  the  software.  a  majority  of  libraries   also  offer  a  variety  of  software  training  sessions,  workshops,  and  give  presentations  to  the  campus   community.  all  this  is  made  possible  through  the  library’s  commitment  to  this  service  area  and  the   availability  of  highly  trained  professional  staff,  most  who  hold  a  masters  or  doctoral  degree.  the   library  has  truly  established  itself  as  the  go-­‐to  location  on  campus  for  spatial  mapping  and  analysis.   this  role  has  only  strengthened  in  the  years  since  the  launch  of  the  arl  gis  literacy  project

retrieval using a middleware approach danijela boberić krstićev information technology and libraries | march 2013 54 abstract this paper explores the use of a mediator/wrapper approach to enable the search of an existing library management system using different information retrieval protocols. it proposes an architecture for a software component that will act as an intermediary between the library system and search services. it provides an overview of different approaches to add z39.50 and search/retrieval via url (sru) functionality using a middleware approach that is implemented on the bisis library management system. that wrapper performs transformation of contextual query language (cql) into lucene query language. the primary aim of this software component is to enable search and retrieval of bibliographic records using the sru and z39.50 protocols, but the proposed architecture of the software components is also suitable for inclusion of the existing library management system into a library portal. the software component provides a single interface to server-side protocols for search and retrieval of records. additional protocols could be used. this paper provides practical demonstration of interest to developers of library management systems and those who are trying to use open-source solutions to make their local catalog accessible to other systems. introduction information technologies are changing and developing very quickly, forcing continual adjustment of business processes to leverage the new trends. these changes affect all spheres of society, including libraries. there is a need to add new functionality to existing systems in ways that are cost effective and do not require major redevelopment of systems that have achieved a reasonable level of maturity and robustness. this paper describes how to extend an existing library management system with new functionality supporting easy sharing of bibliographic information with other library management systems. one of the core services of library management systems is support for shared cataloging. this service consists of the following activities: a librarian when processing a new bibliographical unit first checks whether the bibliographic unit has already been recorded in another library in the world. if it is found, then the librarian stores that electronic records to his/her local database of bibliographic records. in order to enable those activities, it is necessary that standard way of communication between different library management systems exists. currently, the well-known standards in this area are z39.501 and sru.2 danijela boberić krstićev (dboberic@uns.ac.rs) is a member department of mathematics and informatics, faculty of sciences, university of novi sad, serbia. mailto:dboberic@uns.ac.rs information retrieval using a middleware approach | krstićev 55 in this paper, a software component that integrates services for retrieval bibliographic records using the z39.50 and sru standard is described. the main purpose of that component is to encapsulate server sides of the appropriate protocols and to provide a unique interface for communication with the existing library management system. the same interface may be used regardless of which protocols are used for communication with the library management system. in addition, the software component acts as an intermediary between two different library management systems. the main advantage of the component is that it is independent of library management system with which it communicates. also, the component could be extended with new search and retrieval protocols. by using the component, the functionality of existing library management systems would be improved and redevelopment of the existing system would not be necessary. it means that the existing library management system would just need to provide an interface for communication with that component. that interface can even be implemented as an xml web service. standards used for search and retrieval the z39.50 standard was one of the first standards that defined a set of services to search for and retrieve data. the standard is an abstract model that defines communication between the client and server and does not go into details of implementation of the client or server. the model defines abstract prefixes used for search that do not depend on the implementation of the underlying system. it also defines the format in which data can be exchanged. the z39.50 standard defines query language type-1, which is required when implementing this standard. the z39.50 standard has certain drawbacks that new generation of standards, like sru, is trying to overcome. sru tries to keep functionality defined by z39.50 standard, but to allow its implementation using current technologies. one of the main advantages of the sru protocol, as opposed to z39.50, is that it allows messages to be exchanged in a form of xml documents, which was not the case with the z39.50 protocol. the query language used in sru is called contextual query language (cql).3 the sru standard has two implementations, one in which search and retrieval is done by sending messages via the hypertext transfer protocol (http) get and post methods (sru version) and the other for sending messages using the simple object access protocol (soap) (srw version). the main difference between sru and srw is in the way of sending messages.4 the srw version of the protocol packs messages in the soap envelope element, while the sru version of the protocol sends messages based on parameter/value pairs that are included in the url. another difference between the two versions is that the sru protocol for messages transfer uses only http, while srw, in can use secure shell (ssh) and simple mail transfer protocol (smtp), in addition to http. information technology and libraries | march 2013 56 related work a common approach for adding sru support to library systems, most of which already support, the z39.50 search protocol,5 has been to use existing software architecture that supports the z39.50 protocol. simultaneously supporting both protocols is very important because individual libraries will not decide to move to the new protocol until it is widely adopted within the library community. one approach in the implementation of a system for retrieval of data using both protocols is to create two independent server-side components for z39.50 and sru, where both software components access a single database. this approach involves creating a server implementation from the scratch without the utilization of existing architectures, which could be considered a disadvantage. figure 1. software architecture of a system with separate implementations of serverside protocols this approach is good if there is an existing z39.50 or sru server-side implementation, or if there is a library management system, for example, that supports just the z39.50 protocol, but has open programming code and allows changes that would allow the development of an sru service. the system architecture that is based on this approach is shown in figure 1 as a unified modeling language (uml) component diagram. in this figure, the software components that constitute the implementation of the client and the server side for each individual protocol are clearly separated, while the database is shared. the main disadvantage of this approach is that adding support for new search and retrieval protocols requires the transformation of the query language supported by that new protocol into the query language of target system. for example, if the existing library management system uses a relational database to store bibliographic records, for every a new protocol added, its query language must be transformed into the structured query language (sql) supported by the database. z39.50 server side sru server side database z39.50 client side sru client side zservice sruservice jdbc information retrieval using a middleware approach | krstićev 57 however, in most commercial library management systems that support server-side z39.50, local development and maintenance of additional services may not be possible due to the closed nature of the systems. one of the solutions in this case would be to create a so-called “gateway” software component that implements both an sru server and a z39.50 client, used to access the existing z39.50 server. that is, if a sru client's application sends search request, the gateway will accept that request, transform it into the z39.50 request and forward the request to the z39.50 server. similarly, when the gateway receives a response from the z39.50 server, the gateway will transform this response in sru response and forward it to the client. in this way, the client will have the impression that communicates directly with the sru server, while the existing z39.50 server will think that it sends response directly to the z39.50 client. figure 2 presents a component diagram that represents the architecture of the system that is based on this approach. figure 2. software architecture of a system with a gateway the software architecture shown in the figure 2 is one of the most common approaches and is used by the library of congress (lc),6 which uses the commercial voyager7 library information system, which allows searching by the z39.50 protocol. in order to support search of the lc database using sru, indexdata8 developed the yazproxy software component,9 which is an sruz39.50 gateway. the same idea10 was used in the implementation of the "the european library”11 database sru client side jdbc gateway sru server side z39.50 client side srutoz3950converter zservice z39.50 server side sruservice information technology and libraries | march 2013 58 portal, which aims to provide integrated access to the major collections of all the european national libraries. another interesting approach in designing software architecture for systems dealing with retrieval of information can be observed in the systems involved in searching heterogeneous information sources. the architecture of these systems is shown in figure 3. the basic idea in most of these systems is to provide the user with a single interface to search different systems. this means that there is a separate component that will accept a user query and transform it into a query that is supported by the specific system component that offers search and data retrieval. this component is also known as a mediator. a separate wrapper component must be created for each system to be searched, to convert the user's query to a query that is understood by the particular target system.12 figure 3. architecture with the mediator/wrapper approach figure 3 shows a system architecture that enables communication with three different systems (system1, system2 and systemn), each of which may use a different query language and therefore need different wrapper components (wrapper1, wrapper2 and wrappern ). in this architecture, each system can be a new mediator component that will interact with other systems. that is, the wrapper component can communicate with the system or with another mediator. the role of the mediator is to accept the request defined by the user and send it to all wrapper components. the wrapper components know how to transform the query that is sent by a mediator into a query that is supported by the target system with which the wrapper communicates. in addition, the wrapper has to transform data received from the target system in a format prescribed by the mediator. communication between client applications and the mediator

information retrieval using a middleware approach | krstićev 59 may be through one of the protocols for search and retrieval of information, for example through the sru or z39.50 protocols, or it may be a standard http protocol. systems in which the architecture is based on the mediator/wrapper approach are described in several papers. coiera et al (2005)13 describe the architecture of a system that deals with the federated search of journals in the field of medicine, using the internal query language unified query language (uql). for each information source with which the system communicates, a wrapper was developed to translate queries from uql into the native query language of the source. the wrapper also has the task of returning search results to the mediator. those results are returned as an xml document, with a defined internal format called a unified response language (urel). as an alternative to using particular defined languages (uql and urel), a cql query language and the sru protocol could be used. another example of the use of mediators is described by cousins and sanders (2006),14 who address the interoperability issues in cross-database access and suggest how to incorporate a virtual union catalogue into the wider information environment through the application of middleware, using the z39.50 protocol to communicate with underlying sources. software component for services integration this paper describes a software component that would enable the integration of services for search and retrieval of bibliographic records into an existing library system. the main idea is that the component should be modular and flexible in order to allow the addition of new protocols for search and easy integration into the existing system. based on the papers analyzed in the previous section, it was concluded that a mediator/wrapper approach would work best. the architecture of system that would include the component and that would allow search and retrieval of bibliographic records from other library systems is shown in figure 4. z39.50 client sru client library information system recordmanager intermediary mediator wrapper z39.50 server sru server information technology and libraries | march 2013 60 figure 4. architecture of system for retrieval of bibliographic records in figure 4, the central place is occupied by the intermediary component, which consists of a mediator component and a wrapper component. this component is an intermediary between the search service and an existing library system. the library system provides an interface (recordmanager) which is responsible for returning records that match the received query. figure 4 also shows the components that are client applications that use specific protocols for communication (sru and z39.50), as well as the components that represent the server-side implementation of appropriate protocols. this paper will not describe the architecture of components that implement the server side of the z39.50 and sru protocols, primarily because there are already a lot of open-source solutions15 that implement those components and can easily be connected with this intermediary component. in order to test the intermediary component, we used the server side of the z39.50 protocol developed through the jafer project16 ; for the sru server side, we developed a special web service in the java programming language. in further discussion, it is assumed that the intermediary component receives queries from server-side z39.50 and sru services, and that this component does not contain any implementation of these protocols. the mediator component, which is part of the intermediary component, must accept queries sent by the server-side search and retrieval services. the mediator component uses its own internal representation of queries, so it is therefore necessary to transform received queries into the appropriate internal representation. after that, the mediator will establish communication with the wrapper component, which is in charge of executing queries in existing library system. the basic role of the wrapper component is to transform queries received from the mediator into queries supported by library system. after executing the query, the wrapper sends search results as an xml document to the mediator. before sending those results to server side of protocol, the mediator must transform those results into the format that was defined by the client. mediator software component the mediator is a software component that provides a unique interface for different client applications. in this study, as shown in figure 4, a slightly different solution was selected. instead of the mediator communicating directly with the client application, which in the case of protocols for data exchange is client side of that protocol, it actually communicates with the server components that implement the appropriate protocols, and the client application exchanges messages with the corresponding server-side protocol. the z39.50 client exchanges messages with the appropriate z39.50 server, and it communicates with the mediator component. a similar process is done when communication is done using the sru protocol. what is important to emphasize is that the z39.50 and sru servers communicate with the mediator through a unified user interface, represented in figure 5 by class mediatorservice. in this way the same method is used to submit the query and receive results, regardless of which protocol is used. that means information retrieval using a middleware approach | krstićev 61 that our system becomes more scalable and that it is possible to add some new search and retrieval protocols without refactoring the mediator component. figure 5 shows the uml class diagram that describes the software mediator component. the mediatorservice class is responsible for communication with the server-side z39.50 and sru protocols. this class accepts queries from the server side of protocols and returns bibliographic records in the format defined by the server. the mediator can accept queries defined by different query languages. its task is to transform these queries to an internal query language, which will be forwarded to the wrapper component. in this implementation, accepted queries are transformed into an object representation of cql, as defined by the sru standard. one of the reasons for choosing cql is that concepts defined in the z39.50 standard query language can be easily mapped to the corresponding concepts defined by cql. cql is semantically rich, so can be used to create various types of queries. also, because it is based on the concept of context set, it is extensible and allows usage of various types of context sets for different purposes. so, cql is not just limited to the function of searching bibliographic material. it could, for example, be used for searching geographical data. accordingly, it was assumed that cql is a general query language and that probably any query language could be transformed into it. in this implementation, the object model of cql query defined in project cqljava17 was used. in the case that there is a new query language, it would be necessary to perform mapping of the new query language into cql or to extend the object model of cql with new concepts. this implementation of the mediator component could transform two different types of queries into the cql object model. currently, it can transform type-1 queries (used by z39.50) and cql queries into cql object representation. to to add a new query language, it would just be necessary to add a new class that would implement the interface queryconverter shown in figure 5, but the architecture of component mediator remains the same. one task of the mediator component is to return records in the format that was defined by the client that sent the request. information technology and libraries | march 2013 62 figure 5. uml class diagram of mediator component as the mediator communicates with the z39.50 and sru server side, the task of the z39.50 and sru server side will be to check whether the format that the client requires is supported by the underlying system. if it is not supported, the request is not sent to mediator. otherwise, the mediator ensures the transformation of retrieved records into the chosen format. the mediator obtains bibliographic records from the wrapper in the form of an xml document that is valid according to the appropriate xml schema.18 the xml schema allows the creation of an xml document describing bibliographic records according to the unimarc19 or marc2120 format. the current implementation of the mediator component supports transformation of bibliographic records into an xml document that can be an instance of the unimarcslim xml schema,21 the marc21slim xml schema,22 or the dublin core xml schema.23 adding support for a new format would require creating a new class that would extend the class recordserializer (figure 5). because this mediator component works with xml, the transformation of bibliographic records into a new format also could be done by using exstensible stylesheet language transformations (xslt). 0..11..1 0..1 1..* 0..1 0..1 mediatorservice + getrecords (object query, string format) :

serialize (string r) : sting information retrieval using a middleware approach | krstićev 63 wrapper software component the wrapper software component is responsible for ensuring communication between the mediator and the existing library system. that is, the wrapper component is responsible for transforming the cql object representation into a concrete query that is supported by the existing library system and for obtaining results that match the query. implementation of the wrapper component directly depends on the architecture of the existing library system. figure 7 proposes a possible architecture of the wrapper component. this proposed architecture assumes that the existing library system provides some kind of service that will be used by the wrapper component to send the query and obtain results. the recordmanager interface in figure 7 is an example of such a service. recordmanager has two operations, one which executes the query and returns the number of hits and the second operation which returns bibliographic records. this proposed solution is useful for libraries that use a library management system that can be extended. it may not be appropriate for libraries using an “off the self” library management system that cannot be extended. the proposed architecture of the wrapper component is based on a strategy design pattern,24 primarily because of the need for transformation of the cql query into a query that is supported by the library system. according to the cql concept of context sets, all prefixes that can be searched are grouped in context sets, and these sets are registered with the library of congress. the concept of context sets enables specific communities and users to define their own prefixes, relations, and modifiers without fear that their name will be identical to the name of prefix defined in another set. that is, it is possible to define two prefixes with the same name, but they belong to different sets and therefore have different semantics. cql offers the possibility of combining in a single query elements that are defined in different context sets. when parsing a query, it is necessary to check which context set a particular item belongs to and then to apply appropriate mapping of the element from the context set to the corresponding element defined by the query language used in the library system. the strategy design pattern includes patterns that describe the behavior of objects (behavioral patterns), which determine the responsibility of each object and the way in which objects communicate with each other. the main task of a strategy pattern is to enable easy adjustment of the algorithm that is applied by an object at runtime. strategy pattern defines a family of algorithms, each of which is encapsulated in a single object. figure 6 is shows a class diagram from the book “design patterns: elements of reusable object-oriented software,“25 which describes basic elements of strategy patterns. information technology and libraries | march 2013 64 figure 6. strategy design pattern the basic elements of this pattern are the classes context, strategy, concretestrategya and concretestrategyb. the class context is in charge of choosing and changing algorithms in a way that creates an instance of the appropriate class, which implements the interface strategy. interface strategy contains the method algorityinterface(), which should implement all classes that implement that interface. class concretestrategya implements one concrete algorithm. this design pattern is used when transforming cql queries primarily because cql queries can consist of elements that belong to different context sets, whose elements are interpreted differently. classes context, strategy, cqlstrategy and dcstrategy, shown in figure 7, are elements of strategy pattern responsible for mapping concepts defined by cql. the class context is responsible for selection of appropriate strategies for parsing, depending on which context set the element that is going to be transformed belongs to. class cqlstrategy and dcstrategy are responsible for mapping the elements belonging respectively to the cql or dublin core context set in the appropriate elements of a particular query language used by the library system. the use of strategy pattern makes it possible, in real time, to change the algorithm that will parse the query depending on what context set is used. the described implementation of a wrapper component enables the parsing of queries that contain only elements that belong to cql and/or the dublin core context set. in order to provide support for a new context set, a new implementation of interface strategy (figure 7) would be required, including an algorithm to parse the elements defined by this new set. information retrieval using a middleware approach | krstićev 65 figure 7. uml class diagram of wrapper component integration of intermediary software components into the bisis library system the bisis library system was developed at the faculty of science and the faculty of technical sciences in novi sad, serbia, and has had several versions since its introduction in 1993. the fourth and current version of the system is based on xml technologies. among the core functional units of bisis26 are: • circulation of library material • cataloging of bibliographic records • indexing and retrieval of bibliographic records • downloading bibliographic records through z39.50 protocol • creation of a card catalog • creation of statistical reports an intermediary software component has been integrated into the bisis system. the intermediary component was written in the java programming language and implemented as a web application. communication between server applications that support the z39.50 and sru protocols and the intermediary component is done using the software package hessian.27 hessian offers a simple implementation of two protocols to communicate with web services, a binary protocol and its corresponding xml protocol, both of which rely on http. use of hessian package makes it easy to create a java servlet on the server side and proxy object on client-side, which will be used to 0..1 1..1 0..11..1 0..1 1..1 context + + + setstrategy (string strategy) mapindext ounderlayingprefix (string index) parseoperand

makequery (cqlnode cql, object underlayingquery) : string[] : object information technology and libraries | march 2013 66 communicate with the servlet. in this case, the proxy object is deployed on the server side of protocol and the intermediary component contains a servlet. communication between the intermediary and bisis is also realized using the hessian software package, which leads to the possibility of creating a distributed system because the existing library system, the intermediary component, and server applications that implement the protocols can be located on physically separate computers. the bisis library system uses the lucene software package for indexing and searching. lucene has defined its own query language,29 so the wrapper component that is integrated into bisis has to transform to the cql query object model the object representation of the query defined by lucene. therefore the wrapper first needs to determine to which context set the index belongs and then apply the appropriate strategy for mapping the index. the rules for mapping the index to lucene fields are read from the corresponding xml document that is defined for every context set. listing 1 below provides an example of an xml document that contains some rules for mapping indexes of the dublin core context set to lucene index fields. the xml element index represents the name of index which is going to be mapped, while the xml element mappingelement contains the name of lucene field. for example, the title index defined in the dublincore context set, which denotes search by title of the publication, is mapped to the field ti, which is used by the search engine of bisis system. <?xml version="1.0" encoding="utf-8"?> <contextset identifier="info:srw/cql-context-set/1/dc-v1.1" name="dc"> <indexes> <index> <name>title</name> <mappingelement>ti</mappingelement> </index> <index> <name>creator</name> <mappingelement>au</mappingelement> </index> <index> <name>subject</name> <mappingelement>sb</mappingelement> </index> </indexes> </contextset> listing 1. xml document with rules for mapping the dublincore context set after the index is mapped to corresponding fields in lucene, a similar procedure is repeated for a relationship that may belong to some other context set or may have modifiers that belong to some information retrieval using a middleware approach | krstićev 67 other context set. it is therefore necessary to change the current strategy for mapping into a new one. by doing this, all elements of the cql query are converted into a lucene query, so the new query can be sent to bisis to be executed. approximately 40 libraries in serbia currently use the bisis system, which includes a z39.50 client, allowing the libraries to search the collections of other libraries that support communication through the z39.50 protocol. by integrating the intermediary component in the bisis system, non-bisis libraries may now search the collections of libraries that use bisis. as a first step, the intermediary component was just integrated in a few libraries, without any major problems. the component is most useful to the city libraries that use system bisis, because they have many branches, which can now search and retrieve bibliographic records from their central libraries. the component could potentially be used by other library management system, assuming the presence of an appropriate wrapper component to transform cql to the target query language. conclusion this paper describes an independent, modular software component that enables the integration of a service for search and retrieval of bibliographic records into an existing library system. the software component provides a single interface to server-side protocols to search and retrieve records, and could be extended to support additional server-side protocols. the paper describes the communication of this component with z39.50 and sru servers. the software component was developed for integration with the bisis library system, but is an independent component that could be integrated in any other library system. the proposed architecture of the software component is also suitable for inclusion of the existing library system into a single portal. the architecture of the portal should involve one mediator component whose task would be to communicate with wrapper components of individual library systems. each library system would implement its own search and store functionalities and could function independently of the portal. the basic advantage of this architecture is that it is possible to include new library systems that provide search services. it is only necessary to add a new wrapper that will perform the appropriate transformation of the query obtained from the mediator component in a query that the library system can process. the task of the mediator is to send queries to the wrapper, while each wrapper can establish communication with a specific library system. after obtaining the results from underlying library system, the mediator should be able to combine results, remove duplicate, and sort results. in this way end user would have impression that he has been searched a single database. references 1. “information retrieval (z39.50): application service definition and protocol specification,”

james e. powell, daniel alcazar, matthew hopkins, robert olendorf, tamara m. mcmahon, amber wu, and linn collinsgraphs in libraries: a primer answer routine searches is compelling. how, we wonder, can we bring a bit of google to the library world? google harvests vast quantities of data from the web. this data aggregation is obviously complex. how does google make sense of it all so that it can offer searchers the most relevant results? answering this question requires understanding what google is doing, which requires a working knowledge of graph theory. we can then apply these lessons to library systems, make sense of voluminous bibliometric data, and give researchers tools that are as effective for them as google is for web surfers. just as web surfers want to know which sites are most relevant, researchers want to know which of the relevant results are the most reliable, the most influential, and of the highest quality. can quantitative metrics help answer these qualitative questions? the more deeply libraries and librarians can mine relationships between articles and authors and between subjects and institutions, the more reliable are their metrics. suppose some librarians want to compare the relative influence of two authors. they might first look at the authors’ respective number of publications. but are those papers of equally high quality? they might next count all citations to those papers. but are the citing articles of high quality? deeper still, they might assign different weights to each citing article using its own number of citations. at each step, whether realizing it or not, they are applying graph theory. with deeper knowledge of this subject, librarians can embrace complexity and harness it for research tools of powerful simplicity. ■■ pagerank and the global giant graph indexing the web is a massive challenge. the internet is a network of computer hardware resources so complex that no one really knows exactly how it is structured. in fact, researchers have resorted to conducting experiments to discern the structure and size of the internet and its potential vulnerability to attacks. representations of the data collected by these experiments are based on network whenever librarians use semantic web services and standards for representing data, they also generate graphs, whether they intend to or not. graphs are a new data model for libraries and librarians, and they present new opportunities for library services. in this paper we introduce graph theory and explore its real and potential applications in the context of digital libraries. part 1 describes basic concepts in graph theory and how graph theory has been applied by information retrieval systems such as google. part 2 discusses practical applications of graph theory in digital library environments. some of the applications have been prototyped at the los alamos national laboratory research library, others have been described in peer-reviewed journals, and still others are speculative in nature. the paper is intended to serve as a high-level tutorial to graphs in libraries. part 1. introduction to graph theory complexity surrounds us, and in the twenty-first century, our attempts at organization and structure sometimes lead to more complexity. in layman’s terms, complexity refers to problems and objects that have many distinct but interrelated issues or components. there also is an interdisciplinary field referred to as “complex systems,” which investigates emergent properties, such as collective intelligence.1 emergent properties are an embodiment of the old adage “the whole is greater than the sum of its parts.” these are behaviors or characteristics of a system “where the parts don’t give a real sense of the whole.”2 libraries reside at the nexus of these two definitions: they are creators and caretakers of complex data sets (metadata), and they are the source of explicit records of the complex and evolving intellectual and social relationships underlying the evolution of knowledge. digital libraries are complex systems. patrons visit libraries hoping to find some order in complexity or to discover a path to new knowledge. instead, they become the integration point for a complex set of systems as they juggle resource discovery by interacting with multiple systems, either overtly or via federated search, and by contending with multiple vendor sites to retrieve articles of interest. contrast this with google’s simple approach to content discovery: a user enters a few terms in a single box, and google returns a large list of results spanning the internet, placing the most relevant results at the top of this list. no one would suggest using google for all research needs, but its

makes sense to consider the fact that some relationships are more influential than others. for example, a relationship with the president of the company is more significant than a relationship with a coworker, since it is a safe assumption that a direct relationship with the company leader will increase influence. so we assign weights to the edges based on who the edge connects to. google does something similar. all the webpages they track have centrality values, but google’s weighting algorithm takes into account the relative importance of the pages that connect to a given resource. the weighting algorithm bases importance on the number of links pointing to a page, not the page’s internal content, which makes it difficult for website authors to manipulate the system and climb the results ladder. so if a given webpage science, also known as graph theory. this is not the same network that ties all the computers on the internet together, though at first glance it is a similar idea. network science is a technique for representing the relationships between components of a complex system.3 it uses graphs, which consist of nodes and edges, to represent these sets of relationships. generally speaking, a node is an actor or object of some sort, and an edge is a relationship or property. in the case of the web, universal resource locators (urls) can be thought of as nodes, and connections between pages can be thought of as links or edges. this may sound familiar because the semantic web is largely built around the idea of graphs, where each pair of nodes with a connecting edge is referred to as a triple. in fact, tim berners-lee refers to the semantic web as the global giant graph—a place where statements of facts about things are published online and distinctly addressable, just as webpages are today.4 the semantic web differs from the traditional web in its use of ontologies that place meaning on the links and in the expectation that nodes are represented by universal resource identifiers (uris) or by literal (string, integer, etc.) values, as shown in figure 1, where the links in a web graph have meaning in the semantic web. semantic web data are a form of graph, so graph analysis techniques can be applied to semantic graphs, just as they are applied to representations of other complex systems, such as social networks, cellular metabolic networks, and ecological food webs. herein lies the secret behind google’s success: google builds a graph representation of the data it collects. these graphs play a large role in determining what users see in response to any given query. google uses a graph analysis technique called eigenvector centrality.5 in essence, google calculates the relative importance of a given webpage as a function of the importance of the pages that point to it. a simpler centrality measure is called degree centrality. degree centrality is simply a count of the number of edges a given node has. in a social network, degree centrality might tell you how many friends a given person has. if a person has edges representing friendship that connect him to seventeen other nodes, representing other people in the network, then his degree value is seventeen (see figure 2). if a person with seventeen friends has more friendship edges than any other person in the network, then he has the highest degree centrality for that network. eigenvector centrality expands on degree centrality. consider a social network that represents the amount of figure 1. a traditional web graph is compared to a corresponding semantic web graph. notice that replacing traditional web links with semantic links facilitates a deeper understanding of how the resources are related. graphs in libraries: a primer | powell et al. 159 networks evidence for the evolution of metabolic processes.7 chemists have used networks to model reactions in a step-wise fashion by “editing” graphs representing models of molecules and their reactivity,8 and they also have used graphs to better comprehend phase transition states, such as the freezing of water or the emergence of superconductivity when a material is cooled.9 economists have used graphs to model market trades and the effects of globalization.10 infectious disease specialists have used networks to model the spread of disease and to evaluate prospective vaccination plans.11 sociologists have modeled the complex interactions of people in communities.12 and in libraries, computer scientists have explored citation networks and coauthorship networks,13 and they have developed maps of science that integrate scientific papers, their topics, the journals in which they appear, and comsumers’ usage patterns to provide a new view of the pursuit of science.14 network science can make complexity more comprehensible by representing a subset of actors and relationships in a complex system as a graph. these has only two edges, it may still rank higher than a more connected page if one of the pages that links to it has a large number of pages pointing to it (see figure 3). this weighted degree centrality measure is eigenvector centrality, and a higher eigenvector centrality score causes a page to show up closer to the top of a google results set. the user never sees a graph, but this graphbased approach to exploring a complex system (the web), works quite well for routine web searches. ■■ graph theory graph theory, also known as network science, has evolved tremendously in the last decade. for example, information scientists have discovered hubs in the web that connect large numbers of pages, and if removed, disconnect large portions of the network.6 biologists have begun to explore cellular processes, such as metabolism, by modeling these processes as networks and have even found in these figure 2. friendship network figure 3. node 2 ranks higher than node 1 because node 3, which connects to node 2, has more incoming links than node 1. node 3 is deemed more important than node 9, which has no incoming links. 160 information technology and libraries | december 2011 as subgraphs, e.g., in the case where a person has two friends who are also mutual friends. small world networks have numerous highly interconnected subgroups called clusters. these may be distributed throughout the network in a regular fashion, with a few random connections that connect the otherwise disconnected clusters. these random links have the effect of greatly reducing the path length between any two nodes and explain the oft-cited six degrees of separation that connect all people to one another. in social networks, agency is often described as the mechanism by which graphs can then be explored visually and mathematically. graphs can be used to represent systems as they are, to extract subsets of these systems, or to discover wholly artificial collections of relationships between components of a speculative system. data also can be represented as graphs when they consist of “measurements that are either of or from a system conceptualized as a network.”15 in short, graphs offer a continuum of techniques for comprehending complexity and are suitable either for a layman with casual interest in a topic or a serious researcher ferreting out discrete details. at the core of network science is the graph. as stated earlier, a graph is a collection of nodes and the edges that connect some of those nodes, together representing a set of actors and relationships in a type of system. relationships can be unidirectional (e.g., in a social network, when the information flows from one person to another) or bidirectional (e.g., when the information flows back and forth between two individuals). relationships also can vary in significance and can be assigned a weight—for example, a person’s relationship to his or her supervisor might be weighted more heavily than a person’s relationship to his or her peers. a graph can consist of a single type of node (for subjects) and a single type of edge connecting those nodes (for predicates). these are called unipartite graphs. from the standpoint of graph theory, these are the easiest types of graphs to work with. graphs that represent two relationships (bipartite) or more are typically reduced to unipartite graphs in the process of exploring them because the vast majority of techniques for evaluating graphs were developed for graphs that address a single relationship between a set of nodes. ■■ global properties of graphs there are other aspects of graphs to consider, sometimes referred to as “global graph properties.”16 there are two basic classes of networks: homogeneous networks and inhomogeneous networks.17 these graphs exhibit characteristics that may not be comprehensible by close examination (e.g., by examining degree centrality, node clustering, or paths within a graph)18 but may be apparent, depending on the size and the way in which the graph is rendered, merely by looking at a visualization of the graph. in homogeneous graphs, nodes have no significant difference between their number of connections. examples include random graphs, complete graphs, and small world networks. in random graphs there is an equal probability that any two nodes will be connected (see figure 4), while in complete graphs (see figure 5) all nodes are connected with one another. random graphs are often used as tools to evaluate networks that describe real systems. complete graphs might occur in social networks figure 4. a random graph. any given node has an equal probability of being linked to any other node figure 5. a complete graph. all nodes are connected to all other nodes graphs in libraries: a primer | powell et al. 161 building blocks of networks.20 a three-node feedback motif is a set of nodes where the edges between them form a triangle and the edges are directional. in other words, node a is connected to (and might convey some information to) node b; node b, in turn, has the same relationship with node c; and node c is connected to (and conveys information back to) node a. in digital libraries, for example, if similar papers exhibit the same pattern of connectivity to a group of subject or keyword categories, motifs will make it possible to readily identify the topical overlap between them. collections of nodes that have a high degree of connectivity with each other are called clusters.21 in many complex systems, clusters are formed by preferential attachment. a group of highly clustered nodes that have low connectivity to the larger graph is known as a clique. while there are other aspects of graphs that can be explored, these four—node centrality measures, paths between nodes, motifs, and clustering—are accessible to most users and are significant in graphs representing bibliographic metadata and textual content. this will become clearer in the examples that follow. ■■ quantitative evaluation of graphs returning now to centrality measures, two of particular interest in digital libraries are degree centrality and betweenness centrality (or flow centrality). an interesting aspect of graphs is that, regardless of the data being represented, centrality measures and clustering characteristics often reveal important clues about the system that the data these random links get established. agency refers to the idea that multiple, often unpredictable actions on the part of individuals in a network result in unanticipated connections between people. examples of such actions are hobbies, past work experience, meeting someone new while on a trip to another country—pretty much anything that takes a person outside his or her normal social circles. in the case of inhomogeneous graphs, not all nodes are created equal. one type, scale-free networks, is common in a variety of systems ranging from biological to technological (see figure 6. these exhibit a structure in which a few nodes play a central role in connecting many others. these hubs form as a result of preferential attachment, known colloquially as “the rich get richer.” researchers became aware of scale-free networks as a result of analysis of the web when it was in its infancy. scale-free networks have been documented in biology, social networks, and technological networks. as a result, they are quite important in the field of information science. small world and scale-free networks are typical of complex systems that occur in nature or evolve because of emergent dynamic processes, in which a system self-organizes over time. small world networks provide fast, reliable communication between nodes, while scale-free networks are more fault tolerant, making them ideal for systems such as living cells, which are frequently challenged by the external environment.19 ■■ local properties of graphs below the ten-thousand-foot system-level view of networks, graphs can be scrutinized more closely using many other techniques. we will now consider four broad categories of local characteristics that describe networks and how they are, or could be, applied in digital libraries: node centrality measures, paths between nodes, motifs, and clustering. centrality measures make it possible to determine the importance of a given node in a network. degree centrality, in its simplest form, is simply a count of the number of edges connected to any given node in a network: a node with high-degree centrality has many connections to other nodes compared to a typical node in the graph. paths make it possible to explore the connections between nodes. an author who is two degrees removed from another author—in other words, the friend of a friend of a friend—has a path length of 2. researchers are often interested specifically in the shortest path between a given pair of nodes. many other types of paths can be explored depending on the type of network, but in libraries, paths that describe the flow of ideas or communication between people are most likely to be useful. motifs are the fundamental recurring structures that make up the larger graph, and they often are called the figure 6. example of a scale-free coauthorship network. a few nodes have many links, and most nodes have few or a single link to another node 162 information technology and libraries | december 2011 path that connects a node through other nodes back to itself. within graph visualization tools, the placement of nodes can vary from one layout to another. what matters is not the pictorial representation (though this can be useful), but the underlying relationships between nodes (the topology). along with clustering, paths help differentiate motifs, which are considered to be building blocks of some types of complex networks. since bibliographic metadata represents communication in one form or another, it is often most common to apply social network theory to graphs. but it is also possible to apply various centrality measures to graphs that are not social and to use these to discover significant nodes within those graphs. in part 2 we consider various unipartite and bipartite graphs that might be especially useful for examining digital library metadata. part 2. graph theory applications in digital libraries library systems, by virtue of the content they contain, are complex systems. fielded searches, faceted searches, and full-text searches all allow users to access aspects of the complex system. fielded searches leverage the explicit structure that has been encoded into the metadata describing the resources that users are ultimately trying to find (articles, books, etc). full-text searches enable users to explore in a more free-form manner, subject of course to the availability of searchable text. often, full-text search means the user is searching titles, abstracts, and other content that summarizes a resource, rather than the actual full text of articles and books. even if the user is searching the full content, there are relationships and aspects of the content that are not readily discernible through a full-text search. furthermore, there is not one single, comprehensive digital library—many library systems live in the deep web, that is, they are databases that are not indexed by search engines like google, and so users must describes, whether it’s coauthorship relationships or protein interactions in the cell of a living organism. often the clusters or nodes that exhibit a higher score in some centrality calculation are significant in some meaningful way compared to other nodes. recall that degree centrality refers to how many edges a given node has. degree centrality can vary significantly in strength depending on the relationships that are represented in the graph. consider a graph of citations between papers. while it may be obvious to humans that the mostly highly cited papers will have the highest-degree centrality, computers have no idea what this means. it is still up to humans to lend a degree of comprehensibility to the raw calculation: in other words, to understand that a paper with high-degree centrality is an important paper, at least among the papers the graph represents. betweenness centrality exposes how integral a given node is to a network. basically, without getting into the mathematics, it measures how often a node falls on the shortest path between other nodes. thus, nodes with high betweenness centrality do not necessarily have a lot of edges, but they bridge disparate clusters. in an informational network, the nodes with high betweenness centrality are crucial to information flow, social connections, or collaborations. hubs are examples of nodes with high betweenness centrality. the removal of a hub causes large portions of a network to become detached. in figure 7, the node labeled “folkner, w.m.” exhibits high betweenness centrality, since it connects two clusters together. a cluster coefficient expresses whether a given node in a network is a member of a tightly interlinked collection of nodes, or clique. the cluster coefficient of an entire graph reveals the overall tendency for clustering in a graph, with higher cluster coefficients typical of small world graphs. in other types of graphs, clusters sometimes manifest as homophily; that is, nodes of a given type are highly interconnected with one another and have few connections with nodes of other types. in social networks, this is sometimes referred to as the “birds of a feather” effect. in a more current reference, the effect was explored as a function of the likelihood that someone would “unfriend” an acquaintance on the social networking site facebook.22 in some networks (such as the internet), clusters are connected by hubs, while in others, the hub is the primary connecting node of other nodes. paths refer to the edges that connect nodes. the simplest case of a path is an edge that connects two nodes directly. path analysis addresses the set of edges that connect two nodes that are not, themselves, directly connected. the shortest path, as its name implies, refers to the route that uses the least number of edges to connect from node a to node b and measures the number of edges, not the linear distance. walks and paths refer to a list of nodes between two nodes, with walks allowing repeat visits to nodes, and paths not allowing them. cycles refer to a figure 7. paths in a coauthorship network graphs in libraries: a primer | powell et al. 163 coauthorship (collaboration) networks coauthorship (collaboration) networks are typically small world networks in which crossand interdisciplinary work provides the random links that connect various clusters (see figure 8). these graphs can be explored to determine which researchers are having the most influence in a given field; influence is a function of frequency of authorship. a prime example is the collaboration network graph for paul erdős, a highly productive mathematician. the popularity of his influence in academia has lead to the creation of the erdős number, which is “defined as indicating the topological distance in the graph depicting the co-authorship relations.”23 liu et al. proposed a node analysis measure that they called authorrank, which establishes weighted directed edges between authors. the author ’s authorrank value is a sum of the weighted edges connected to that author.24 these networks also can be used to explore how an idea spreads and what opportunities may exist for future collaborations, as well as many other existing and potential relationships. citation graphs citation graphs more strongly resemble scale-free networks, in which early papers in a given field tend to accumulate more links. such hub papers can be cited hundreds or even thousands of times while most papers are cited far less often or not at all. many researchers have explored citation graphs, though the person often credited with first noting the network characteristics of citation patterns was dereck j. de solla price in 1965.25 more recently, mark newman introduced the concept of what he calls “first mover advantage” to describe the preferential attachment observed in citation networks.26 search each individually. but if more of these systems adopted semantic web standards, they could be explored as graphs, and relationships between different databases would be easier to discern and represent to the user. many libraries have tried to emulate google by incorporating federated search engines with a single search box as an interface. this copies the form of google’s search engine but not its underlying power. to do that, libraries must enhance full-text searches by drawing on relationships. a full-text search will (hopefully) find relevant papers on a given topic, but a researcher often wants to find the best papers on that topic. to meet that need, libraries must harness the information contained in relationships; otherwise each paper is stuck in a vacuum. cited references are one way to connect papers. for researchers and librarians alike, this is a familiar metric for assessing a paper’s relative importance. the web of science and scopus are two databases that perform this function. looked at another way, citation counts are nothing more than degree centrality applied to a simple graph in which papers are nodes and references are edges. thus, in the framework of graph theory, citation analysis is just a small sliver of a world of possible relationships, many of which are unexplored. the following examples outline use case scenarios in which graph techniques are or could be applied to library data, such as bibliographic metadata, to help users find relationships and conduct research. ■■ informational graphs intrinsic to digital library systems there are multiple relationships represented within and between metadata contained in library systems that can be represented as graphs and explored using graph techniques. some of these, such as citation networks, are among the most well-studied informational networks. citation networks are valued because the data describing them is readily accessible and because scientists studying classes of networks have used them as surrogates for exploring scale-free networks. they are often evaluated as static networks (i.e., a snapshot in time) but some also have dynamic characteristics (e.g., they change and grow over time or they allow information-flow analysis). techniques such as pagerank can be used to evaluate information when the importance of a linking resource is as important as the number of links to a resource. multirelational networks can be developed to explore dynamic processes in research fields by using library data to provide the basic topological framework for some of the explorations. figure 8. a coauthorship network 164 information technology and libraries | december 2011 network with three types of nodes: one to represent individual pieces of debris, a second to represent collections of debris that are the original object that the debris is a fragment of, and a third to represent conjunction events (near misses) between objects. another example of graphs being used as tools is the case of developing vaccination strategies to curtail the spread of an infectious disease.30 in this case, networks have been used to determine that one of the best strategies for curtailing the transmission of a disease is to identify and vaccinate hubs, rather than to conduct mass vaccination campaigns. in libraries, graphs as tools could be used to help researchers identify collaboration opportunities, to disambiguate author identities and aggregate related materials, to allow library staff to evaluate the academic contribution of a group of researchers (bibliometrics), and to explore geospatial and temporal aspects of information, including changes in research focus over time. graphs for author name disambiguation author name disambiguation is a long-standing problem in libraries. many resources have been devoted to manual and automatic name authority control, yet the problem remains unsolved. projects such as oclc viaf and efforts to establish unique author identifiers will no doubt improve the situation, but many problems remain.31 meanwhile, we have experimented with an approach to author name matching by generating multirelational graphs. authors subject–author (expertise) graphs graphs that connect authors by subject areas can vary because of the granularity of subject headings (see figure 9). high-level subject headings tend to function as hubs, but more useful relationships are revealed by specific subject headings and author-provided keywords. the map of science merges publications and citations with actual end user usage patterns captured in library systems and deals, in part, with categories of scientific research.27 it clusters publications and visualizes them “as a journal network that outlines the relationships between various scientific domains.” implicit in this a model is the relationship of authors to subject areas. institution–topic and nation–topic (expertise) graphs from a commercial or geopolitical perspective, graphs that represent institutional or national expertise can reveal valuable information for scientists, elected officials, and investors, particularly in networks that represent the change in a given organization or region’s contributions to a field over time. metadata for scientific papers typically includes enough information to generate nodes and edges describing this. the resulting graph can reveal unexpected details, such as national or institutional efforts to nurture expertise in a given field, and the results of those efforts. the visualization of this data may take the form of icons that vary in shape and size depending on various aspects of nodes in the institution-topic network. these visual representations can then be overlaid onto a map, with various visual aspects of the icons also affected by centrality measures applied to a given institution’s contributions.28 ■■ graphs as tools graph representations can be used as tools to explore a variety of complex systems. even systems that do not initially appear to manifest networks of relationships can often be better understood when some aspect of the system is represented as a graph. this approach requires thinking about what aspects of information needs, discovery, or consumption might be represented or evaluated using networks. two interesting examples from other fields will illustrate the point. a 2009 paper in acta astronautica proposed that techniques to reduce the amount of space junk in orbit around the earth could be evaluated using graph theory techniques.29 the authors propose a dynamic multirelational figure 9. a subject–author graph for stephen hawking graphs in libraries: a primer | powell et al. 165 computation over time because it is typically so important to understanding data. allen’s temporal intervals address machine reasoning over disparate means of recording the temporal aspects of events.33 another temporal computing concept that has applicability to graphs is from the memento project, which makes it possible for users to view prior versions of webpages.34 entities in the memento ontology can become predicates in triples, which in turn can become edges in graphs. using graphs, time can be represented as a relationship between objects or as a distinct object within a graph. nodes that connect through a temporal node may overlap, coincide, or co-occur. nodes that cluster around time represent something important about the objects. genomic-document and proteindocument networks many people hoped that mapping the human genome would result in countless medical advances, but the process whereby genes manifest themselves in living organisms turned out to be much more complex—there wasn’t just a simple mapping between genes and organism traits, there were other processes controlled by genes representing additional layers of complexity scientists had not anticipated. today biologists apply network science to these processes to reveal the missing pieces of this puzzle.35 just as the process itself is complex, the information needs of these researchers benefit from a more sophisticated approach. biologists often need to find papers that reference a given gene or protein sequence. and so, representing these relationships (e.g., article–gene) as graphs has the added benefit of making the digital library research data compatible with the methods that biologists already use to document what they know about these processes. although this is a specialized type of graph, a similar approach might be valuable to researchers in a number of scientific disciplines, including materials science, astrophysics, and environmental sciences. graphs of omission one of the less obvious capabilities of network science is to make predictions about complex systems by looking for missing nodes in graphs.36 this has many applications: for example, identifying a hub in the metabolic processes of bacteria can yield new targets for antibiotics, but it is vital to know that interrupting the enzyme that serves as that hub will effectively kill the organism. making predictions about the evolution of research by identifying areas for cross-disciplinary collaboration or areas where little work has been done—enabling a researcher to leverage are the primary nodes of interest, but relationships such as topic areas, titles, dates, and even soundex representations of names also are represented. as one would expect, phonetically similar names cluster around particular soundex representations. shared coauthorship patterns and shared topic areas can reveal that two different names are for the same author as, for example, when a person’s name changes after marriage (see figure 10). graphs for title or citation deduplication string edit distance involves counting the number of changes that would need to be made to one string to convert it to another, and it is one of the most common approaches to deduplicating titles, citations, and author names. multirelational graphs, in which titles are linked to authors, publication dates, and subjects, result in subgraphs that appear virtually identical when two title variants are represented. centrality measures can be applied to unipartite subgraphs of these networks to home in on areas where data duplication may exist. temporal-topic graphs for analyzing the evolution of knowledge over time a particularly active area of research in graph theory is the representation of dynamical systems as networks. a dynamical system is described as a complex system that changes over time.32 computer scientists have developed various strategies and technologies to cope with figure 10. two authors with similar names linked by subject nodes 166 information technology and libraries | december 2011 basis for an on-the-fly search expansion tool. a querysuggestion tool might look at user-entered terms and determine that some are hubs, then suggest related terms from nodes that connect to those hub nodes. remember, graphs need not be visible to be useful! global subject resolution using dbpedia although dbpedia appears to lag behind wikipedia in terms of completeness and scrutiny by domain experts, it offers one mechanism for unifying user-provided tags, author keywords, and library-assigned subject headings with a graph of known facts about a topic. links into and out of dbpedia’s graphs on a given topic would enable serendipitous knowledge discovery through browsing these semantic graphs. viaf linked author data oclc’s effort to convert tens of millions of identity records into graphs describing various attributes of authors promises to enhance exploration of digital library content on the author dimension.42 these authority records contain a wealth of information, linking name variations, basic genealogical data such as birth and death dates, associations with institutions, subject areas, and titles published by authors. although some rough edges need to be smoothed (one of the authors of this paper discovered that his own authorship data was linked with another author of the same name), iterative refinement of this data as it is actually used may enable crowd-sourced the first-mover advantage and thus advance his or her career—is a valuable service that libraries are well positioned to provide (see figure 11). machine-supplied suggestions offer another type of prediction. for example, providing the prompt “did you mean john smith and climate change?” can leverage real or predicted relationships between author and subject (see figure 12). graphs, in turn, can be used to create tools that will simplify an author–subject search. viral concept detection phase transition typically refers to a process in thermodynamics that describes the point at which a material changes from one state of matter to another (e.g., liquid to solid). phase transition also applies to the dispersal of a new idea. interestingly enough, graphs representing matter at the point of phase transition, and graphs representing the spread of a fad in a social network, exhibit the same recognizable pattern of change: suddenly there are links between many more nodes, there’s a dramatic increase in clustering, and something called a giant component emerges.37 in a giant component, all of the nodes in that portion of the graph are interlinked, resulting in a complete graph like figure 5. this is not so different from what one observes when something “goes viral” on the internet. in a library, a dynamic graph showing the usage of new keywords for emerging subject areas would likely reflect a similar pattern. ■■ linked data graph examples cross-collection graphs, or graphs that link data under your control to data published online, can be constructed by building links into the web of linked data.38 linked data refers to semantic graphs of statements that various organizations publish on the web. for example, geonames.org publishes millions of statements about geographic locations on the linked data web.39 as these graphs grow and evolve, opportunities emerge for using this data in combination with your own data in various ways. for example, it would be quite interesting to develop a network representation of library subject headings and their relationships to concepts in the encyclopedic linked data collection known as dbpedia.40 the resulting graph could be used in a variety of ways: for example, to evaluate the consistency of statements made about concepts, to establish semantic links between user-provided tags and concepts,41 or to function as the figure 11. identifying areas for collaboration: a co-author graph with many simple motifs and few clusters might indicate a field ripe for collaboration graphs in libraries: a primer | powell et al. 167 content could be represented and explored as a graph, and some research has already shown that geographic networks—especially those representing human-constructed entities such as cities and transportation networks—exhibit small world characteristics.45 another way graphs can express geographic relationships in useful ways would be in representing the concept of nearness. waldo tobler’s first law of geography states that “everything is related to everything else, but near things are more related than distant things.”46 in practice, human beings define nearness in different ways, so a graph representing a shared concept of nearness would be very valuable, particularly in exploring works associated with biological, ecological, geological, or evolutionary sciences. graph representations of nearness could be developed by librarians working with scientists and could be the geographic equivalent to subject guides and finding aids. they also might be useful across disciplines and would enable machine inferencing across data that include geographic relationships. still other kinds of graphs what might a digital library tool based on graph theory look like? what could it do? it wouldn’t necessarily depict visualizations of graphs (though in some cases visual graphs are the most efficient way to impart concepts). after all, citation databases utilize graph theory, but the user only sees a number (cite count) and lists of articles (citing or cited). in many cases, then, the tool would perform graph evaluation techniques behind the scenes, translating these metrics into simple descriptive queries for the user. for example, a user interested in the most influential papers in his field would enter his subject, and then on the backend, the tool would apply eigenvector centrality to that subject’s citation graph. if the same user finds an especially relevant article, clicking a “find similar articles” button will produce a list of papers in that graph with the shortest path length to the paper in question. researchers also could use this tool to evaluate authors and institutions in various ways: ■■ is my output diverse or specialized compared to my colleagues? the tool assigns a score for each author based on degree centrality in a subject-author graph. ■■ i want to find potential collaborators. the tool returns authors connected to researcher by the shortest path length in a coauthorship graph. ■■ i want to collaborate with colleagues from other departments at my institution. high betweenness centrality quality control that will more rapidly identify and resolve these problems. linked geographic data using geonames it is ironic that the use of networks to describe geographic aspects of the world is in its infancy, considering that many consider leonhard euler’s attempt to find a mathematical solution to the seven bridges of königsberg problem in 1735 to be the birth of the field.43 as some authors have pointed out, geometric evaluation of geographic relationships is actually a poor way to explore geographic relationships.44 graphs can be used to express arbitrary relationships between geographically separated objects, and it is perhaps no accident that our road and railway systems are in fact among the most familiar graphs that people encounter in the real word. a subway map is a graph where subway stations are nodes linked by railway. graphs can represent the relationships between topological features, the visibility of buildings in a city to one another, or the land, sea, and air transportation that links one country to another. geonames supplies a rich collection of geographic information that includes descriptions of geopolitical entities (cities, states, countries), geophysical features, and various names that have been ascribed to these objects. the geographic relationships in intellectual figure 12. find

between two institutions, the more comparable they may be. graphs also enable libraries to reach outside their own data to build connections with other data sets. heterogeneity, which makes relational database representations of arbitrary relationships difficult or impossible, becomes a trivial matter of adding additional nodes and edges to bridge collections. the linked data web defines simple requirements for establishing just such representations, and libraries are wellpositioned to build these bridges. ■■ conclusion for many centuries, libraries have served as repositories for the accumulated knowledge and creative products of civilization, and they contain mankind’s best efforts at comprehending complexity. this knowledge includes scientific works that strive to understand various aspects of the physical world, many of which are complex and require the efforts of numerous researchers over time. since the advent of the dewey decimal system, librarians have worked on many fronts to make this knowledge discoverable and to assist in its evaluation. qualitative evaluation increasingly requires understanding a resource in a larger context. we suggest that this context is itself a complex system, which would benefit from the modeling and quantitative evaluation techniques that network science has to offer. we believe librarians are well positioned to leverage network science to explore and comprehend emergent properties of complex information environments. as motivation for this pursuit, we offer in closing this prescient quote from carl woese, which though focused on the discipline of biology, is equally applicable to the myriad complexities of modern life: “a society that permits biology to become an engineering discipline, that allows that science to slip into the role of changing the living world without trying to understand it, is a danger to itself.”47 references 1. melanie mitchell, complexity: a guided tour (oxford, england; new york: oxford

create website content should have access to website usage statistics to measure their webpages’ effectiveness and refine the pages as necessary.3 with web analytics libraries can increase the effectiveness of their websites, and as marshall breeding has observed, libraries can regularly use website statistics to determine how new webpage content is actually being used and make revisions to the content based on this information.4 several recent studies used google analytics to collect and report website usage statistics to measure website effectiveness and improve their usability.5 while web analytics are useful in a website redesign process, several studies concluded that web usage statistics should not be the sole source of information used to evaluate a website. these studies recommend using click data in conjunction with other website usability testing methods.6 background a lack of research on the use of click analytics in libraries motivated the web services librarian to explore their potential by directly implementing them on the library’s website. she found that there are several click analytics products available and each has its own unique functionality. however, many are commercially produced and expensive. with limited funding, the web services librarian selected google analytics’ in-page analytics, clickheat, and crazy egg because they are either free or inexpensive. each tool was evaluated on the library’s website for over a six month period. because google analytics cannot discern between the same link repeated in multiple places on a webpage. furthermore, she wanted to use website use data to determine the areas of high and low usage on the library’s homepage, and use this information to justify her webpage reorganization decisions. although this data can be found in a google analytics report, the web services librarian found it difficult to easily identify the necessary information within the massive amount of data the reports contain. the web services librarian opted to use click analytics, also known as click density analysis or site overlay, a subset of web analytics that reveals where users click on a webpage.1 a click analytics report produces a visual representation of what and where visitors are clicking on an individual webpage by overlaying the click data on top of the webpage that is being tested. rather than wading through the data, libraries can quickly identify what content users are clicking by using a click analytics report. the web services librarian tested several click analytics products while reassessing the library’s homepage. during this process she discovered that each click analytics tool had different functionalities that impacted their usefulness to the library. this paper introduces and evaluates three click analytics tools, google analytics’ in-page analytics, clickheat, and crazy egg, in the context of redesigning the library’s homepage and discusses the benefits and drawbacks of each. literature review library literature indicates that libraries are actively engaged in interpreting website usage data for a variety of purposes. laura b. cohen’s study encourages libraries to use their website usage data to enhance their understanding of how visitors access and use library websites.2 jeanie m. welch further recommends that all click analytics: visualizing website use data editor’s note: this paper is adapted from a presentation given at the 2010 lita forum click analytics is a powerful technique that displays what and where users are clicking on a webpage helping libraries to easily identify areas of high and low usage on a page without having to decipher website use data sets. click analytics is a subset of web analytics, but there is little research that discusses its potential uses for libraries. this paper introduces three click analytics tools, google analytics’ in-page analytics, clickheat, and crazy egg, and evaluates their usefulness in the context of redesigning a library’s homepage. w eb analytics tools, such as google analytics, assist libraries in interpreting their website usage statistics by formatting that data into reports and charts. the web services librarian at the kraemer family library at the university of colorado, colorado springs wanted to use website use data to reassess the library’s homepage that was crowded with redundant links. for example, all the links in the site’s dropdown navigation were repeated at the bottom of the homepage to make the links more noticeable to the user, but it unintentionally made the page long. to determine which links the web services librarian would recommend for removal, she needed to compare the use or clicks the repetitive links received. at the time, the library relied solely on google analytics to interpret website use data. however, this practice proved insufficient tabatha a. farney (tfarney@uccs.edu) is web services librarian, kraemer family library, university of colorado, colorado springs, colorado. 142 information technology and libraries | september 2011 libraries, outbound links include library catalogs or subscription databases. additional javascript tags must be added to each outbound link for google analytics to track that data.9 once google analytics recognizes the outbound links, their click data will be available in the in-page analytics report. visitors to that page, and outbound destinations, links that navigate visitors away from that webpage. the inbound sources and outbound destinations reports can track outbound links, which are links that have a different domain or url address from the website tracked within google analytics. for in-page analytics google analytics is a popular, comprehensive web analytics tool that contains a click analytics feature called in-page analytics (formerly site overlay) that visually displays click data by overlaying that information on the current webpage (see figure 1). site overlay was used during the library’s redesign process, however, it was replaced by in-page analytics in october 2010.7 the web services librarian reassessed the library’s homepage using in-page analytics, and found that the current tool resolved some of site overlay’s shortcomings. site overlay is no longer accessible in google analytics, so this paper will discuss in-page analytics. essentially, in-page analytics is an updated version of the site overlay (see figure 2). in addition to visually representing click data on a webpage, in-page analytics contains new features including the ability to easily segment data. web analytics expert, avinash kaushik, stresses the importance of segmenting website use data because it breaks down the aggregated data into specific data sets that represents more defined groups of users.8 rather than studying the total number of clicks a link received, an in-page analytics report can segment the data into specific groups of users, such as mobile device users. in-page analytics provides several default segments, but custom segments can also be applied allowing libraries to further filter the data that is constructive to them. in-page analytics also displays a complementing overview report of statistics located in a side panel next to the typical site overlay view. this overview report extracts useful data from other reports generated in google analytics without having to leave the in-page analytics report screen. the report includes the webpage’s inbound sources, also called top referrals, which are links from other webpages leading figure 1. screenshot of google analytics’ defunct site overlay figure 2. screenshot of google analytic’s in-page analytic librarians and technology skill acquisition: issues and perspectives | farney 143click analytics: visualizing website use data | farney 143 services librarian uses a screen capture tool, such as the firefox add-on screengrab13, to collect and archive the in-page analytics reports, but the process is clunky and results in the loss of the ability to segment the data. clickheat labsmedia’s clickheat is an open source heat mapping tool that visually displays the clicks on a webpage using color to indicate the amount of clicks an area receives. similar to in-page analytics, a clickheat heat map displays the current webpage and overlays that page with click data (see figure 3). instead of listing percentages or actual numbers of clicks, the heat map represents clicks using color. the warmer the color, such as yellows, oranges, or reds, the more clicks that area receives; the absence of color implies little to no click activity. each heat map has an indicator that outlines the number of clicks a color represents. a heat map clearly displays the heavily used and underused sections on a webpage making it easy for people with little experience interpreting website usage statistics to interpret the data. however, a heat map is not about exact numbers, but rather general areas of usage. for exact numbers, a traditional, comprehensive web analytics tool is required. clickheat can stand alone or be integrated into other web analytic tools.14 to have a more comprehensive web analytics product, the web services librarian opted to use the clickheat plugin for piwik, a free, open source web analytics tool that seeks to be an alternative to google analytics.15 by itself piwik has no click analytics feature, therefore clickheat is a useful plugin. both piwik and clickheat require access to a web server for installation and knowledge of php and mysql to configure them. because the kraemer family library does not maintain its own web servers, the pages, but it is time consuming and may not be worth the effort since the data are indirectly available.11 a major drawback to in-page analytics is that it does not discern between the same links listed in multiple places on a webpage. instead it tracks redundant links as one link, making it impossible to distinguish which repeated link received more use on the library’s homepage. similarly, the library’s homepage uses icons to help draw attention to certain links. these icons are linked images next to their counterpart text link. since the icon and text link share the same url, in-page analytics cannot reveal which is receiving more clicks. in-page analytics is useless for comparing repetitive links on a webpage, but google reports that they are working on adding this capability.12 as stated earlier, in-page analytics lays the click data over the current webpage in real-time, which can be both useful and limiting. using the current webpage allows libraries to navigate through their site while staying within the in-page analytics report. libraries can follow in the tracks of website users to learn how they interact with the site’s content and navigation. the downside is that it is difficult to compare a new version of a webpage with an older version since it only displays the current webpage. for example, the web services librarian could not accurately compare the use data between the old homepage and the revised homepage within the in-page analytics report because the newly redesigned homepage replaced the old page. comparing different versions of a webpage could help determine whether the new revisions improved the page or not. an archive or export feature would remedy this problem, but in-page analytics does not have this capacity. additionally, an export function would improve the ability to share this report with other librarians without having them login to the google analytics website. currently, the web evaluation of in-page analytics in-page analytics’ advanced segmenting ability far exceeds the old site overlay functionality. segmenting click data at the link level helps web managers to see how groups of users are navigating through a website. for example, in-page analytics can monitor the links mobile users are clicking, allowing web managers to track how that group of users are navigating through a website. this data could be used in designing a mobile version of a site. in-page analytics integrates a site overlay report and an overview report that contains selected web use statistics for an individual webpage. although the overview report is not in visual context with the site overlay view, it combines the necessary data to determine how a webpage is being accessed and used. this assists in identifying possible flaws in a website’s navigation, layout, or content. it also has the potential to clarify misleading website statistics. for instance, google analytics top exit pages report indicates the library’s homepage is the top exit page for the site. exit pages are the last page a visitor views before leaving the site.10 having a high exit rate could imply visitors were leaving the library’s site from the homepage and potentially missing a majority of the library’s online resources. using in-page analytics, it was apparent the library’s homepage had a high number of exits because many visitors clicked on outbound links, such as the library catalog, that navigated visitors away from the library’s website. rather than finding a potential problem, in-page analytics indicated that the homepage’s layout successfully led visitors to a desired point of information. while the data from the outbound links is available in the data overview report, it is not displayed within the site overlay view. it is possible to work around this problem by creating internal redirect 144 information technology and libraries | september 2011 the precise number of clicks is available in traditional web analytics reports. installing and configuring clickheat is a potential drawback for some libraries that do not have access to the necessary technology or staff to maintain it. even with access to a web server and knowledgeable staff, the web services librarian still experienced glitches implementing clickheat. she could not add clickheat to any high trafficked webpage because it created a slight, but noticeable, lag in response time to any page it was added. the cause was an out-of-box configuration setting that had to be fixed by the campus’ information technology department.17 another concern for libraries is that clickheat is continuously being developed with new versions or patches released periodically.18 like any locally installed software, libraries must plan for continuing maintenance of clickheat to keep it current. just as with in-page analytics, clickheat has no export or archive function. this impedes the web main navigation on the homepage and opted to use links prominently displayed within the homepage’s content. this indicated that either the users did not notice the main navigation dropdown menus or that they chose to ignore them. further usability testing of the main navigation is necessary to better understand why users do not utilize it. clickheat is most useful when combined with a comprehensive web analytics tool, such as piwik. since clickheat only collects data where visitors are clicking, it does not track other web analytics metrics, which limits its ability to segment the click data. currently, clickheat only segments clicks by browser type or screen resolution. additional segmenting ability would enhance this tool’s usefulness. for example, the ability to segment clicks from new visitors and returning visitors may reveal how visitors learn to use the library’s homepage. furthermore, the heat map report does not provide the actual number of clicks on individual links or content areas since heat maps generalize click patterns. web services librarian worked with the campus’ information technology department to install piwik with the clickheat plugin on a campus web server. once installed, piwik and clickheat generate javascript tags that must be added to every page that website use data will be tracked. although piwik and clickheat can be integrated, the tools work separately so two javascript tags must be added to a webpage to track click data in piwik as well as in clickheat. only the pages that contain the clickheat tracking script will generate heat maps that are then stored within the local piwik interface. evaluation of clickheat in-page analytics only tracks links or items that perform some sort of action, such as playing a flash video,16 but clickheat tracks clicks on internal links, outbound links, and even nonlinked objects, such as images. hence, clickheat is able to track clicks on the entire webpage. tracking non-linked objects was unexpectedly useful in identifying potential flaws in a webpage’s design. for instance, within a week of beta testing the library’s redesigned homepage, it was evident that users clicked on the graphics that were positioned closely to text links. the images were intended to draw the user’s attention to the text link, but instead users clicked on the graphic itself expecting it to be a link. to alleviate possible user frustration, the web services librarian added links to the graphics to take visitors to the same destinations as their companion text links. clickheat treats every link or image as its own separate component, so it has the ability to compare the same link listed in multiple places on the same page. unlike in-page analytics, clickheat was particularly helpful in analyzing which redundant links received more use on the homepage. in addition, the heat map also revealed that users ignored the site’s figure 3. screenshot of clickheat’s heat map report librarians and technology skill acquisition: issues and perspectives | farney 145click analytics: visualizing website use data | farney 145 clicks that area has received with the brighter colors representing the higher percentage of clicks. the plus signs can be expanded to show the total number of clicks an item has received, and this number can be easily filtered into eleven predefined allowing crazy egg to differentiate between the same link or image listed multiple times on a webpage. crazy egg displays this data in color-coded plus signs which are located next to the link or graphic it represents. the color is based on the percentage of services librarian’s ability to share the heat maps and compare different versions of a webpage. again, the web services librarian manually archives the heat maps using a screen capture tool, but the process is not the perfect solution. crazy egg crazy egg is a commercial, hosted click analytics tool selected for this project primarily for its advanced click tracking functionality. it is a fee-based service that requires a monthly subscription. there are several subscription packages based on the number of visits and “snapshots.” snapshots are webpages that are tracked by crazy egg. the kraemer family library subscribes to the standard package that allows up to twenty snapshots at one time with a combined total of 25,000 visits a month. to help manage how those visits are distributed, each tracked page can be assigned a specific number of visits or time period so that one webpage does not use all the visits early in the month. once a snapshot reaches its target number of visits or its allocated time period, it automatically stops tracking clicks and archives that snapshot within the crazy egg website.19 the snapshots convert the click data into three different click analytic reports: heat map, site overlay, and something called “confetti view.” crazy egg’s heat map report is comparable to clickheat’s heat map; they both use intensity of colors to show high areas of clicks on a webpage (see figure 4). crazy egg’s site overlay is similar to in-page analytics in that they both display the number of clicks a link receives (see figure 5). unlike in-page analytics, crazy egg tracks all clicks including outbound links as well as nonlinked content, such as graphics, if it has received multiple clicks. every clicked link and graphic is treated as its own separate entity, figure 4. screenshot of crazy egg’s heat map report figure 5. screenshot of crazy egg’s site overlay report 146 information technology and libraries | september 2011 to decide which redundant links to remove from the homepage. the confetti view report was useful for studying clicks on the entire webpage. segmenting this data allowed the web services librarian to identify click patterns on the webpage from a specific group. for example, the report revealed that mobile device users would scroll horizontally on the homepage to click on content, but rarely vertically. she also focused on the time to click segment, which reports how long it took a visitor to click on something, in the confetti view to identify links or areas that took users over half a minute to click. both segments provided interesting information, but further usability testing is necessary to better understand why mobile users preferred not to scroll vertically or why it took users longer to click on certain links. crazy egg also has the ability to archive its snapshots within its profile. this is useful for comparing different versions of a webpage to discover if the modifications were an improvement or not. one goal for the library’s homepage redesign was to shorten the page so users did not have to scroll evaluation of crazy egg crazy egg combines the capabilities of in-page analytcis and clickheat in one tool and expands on their abilities. it is not a comprehensive web analytics tool like google analytics or piwik, but rather is designed to specifically track where users are clicking. crazy egg’s heat map report is comparable to the one freely available in clickheat, however, its site overlay and confetti view reports are more sophisticated than what is currently available for free. the web services librarian found crazy egg to be a worthwhile investment during the library’s homepage redesign because it provided additional context to show how users were interacting with the library’s website. the site overlay facilitated the ability to compare the same link listed in multiple locations on the library’s homepage. not only could the web services librarian see how many clicks the links received, but she could also segment and compare that data to learn which links users were finding faster and which links new visitors or returning visitors preferred. this data helped her segments that include day of week, browser type, and top referring websites. custom segments may be applied if they are set up within the crazy egg profile. the confetti view report displays every click the snapshot recorded and overlays those clicks as colored dots on the snapshot as shown in figure 6. the color of the dot corresponds to specific segment value. the confetti view report uses the same default segmented values used in the site overlay report but here they can be further filtered into defined values for that segment. for example, the confetti view can segment the clicks by window width and then further filter the data to display only the clicks from visitors with window widths under 1000 pixels to see if users with smaller screen resolutions are scrolling down long webpages to click on content. this information is hard to glean from crazy egg’s site overlay report because it focuses on the individual link or graphic. the confetti view report focuses on clicks at the webpage level, allowing libraries to view usage trends on a webpage. crazy egg is a hosted service like google analytics, which means all the data are stored on crazy egg’s web servers and accessed through its website. implementing crazy egg on a webpage is a two-step process requiring the web manager to first set up the snapshot within the crazy egg profile and then add the tracking javascript tags to the webpage it will track. once the javascript tags are in place, crazy egg takes a picture of the current webpage and stores that as the snapshot on which to overlay the click data reports. since it uses a “snapshot” of the webpage, the website manager needs to retake a snapshot of the webpage if there are any changes to it. retaking the snapshot requires only a click of a button to automatically stop the old snapshot and regenerate a new one based on the current webpage without having to change the javascript tags. figure 6. screenshot of crazy egg’s confetti view report librarians and technology skill acquisition: issues and perspectives | farney 147click analytics: visualizing website use data | farney 147 website. next, she will explore ways to automate the process of sharing of website use data to make this information more accessible to other interested librarians. by sharing this information, the web services librarian hopes to promote informed decision making for the library’s web content and design. references 1. avinash kaushik, web analytics 2.0: the art of online accountability and science of customer centricity (indianapolis: wiley, 2010): 81–83. 2. laura b. cohen, “a

however, all provide a distinct picture of how visitors use a webpage. by using all of them, the web services librarian was able to clearly identify and recommend the links for removal. in addition, she identified other potential usability concerns, such as visitors clicking on nonlinked graphics rather than the link itself. a major bonus of using click analytics tools is their ability to create easy to understand reports that instantly display where visitors are clicking on a webpage. no previous knowledge of web analytics is required to understand these reports. the web services librarian found it simple to present and discuss click analytics reports with other librarians with little to no background in web analytics. this helped increase the transparency of why links were targeted for removal from the homepage. as useful as click analytics tools are, they cannot determine why users click on a link, only where they have clicked. click analytics tools simply visualize website usage statistics. as elizabeth black reports, these “statistics are a trail left by the user, but they do not explain the motivations behind the behavior.”20 she concludes that additional usability studies are required to better understand users and their interactions on a website.21 libraries can use the click analytics reports to identify a problem on a webpage, but further usability testing will explain why there is a problem and help library web managers fix the issue and prevent repeating the mistake in the future. the web services librarian incorporated the use of in-page analytics, clickheat, and crazy egg in her web analytics practices since these tools continue to be useful to test the usage of new content added to a webpage. furthermore, she finds that click analytics’ straightforward reports prompted her to share website use data more often with fellow librarians to assist in other decisionmaking processes for the library’s down too much to get to needed links. by comparing the old homepage and the new homepage confetti reports in crazy egg, it was instantly apparent that the new homepage had significantly fewer clicks on its bottom half than the old version. furthermore, comparing the different versions using the time to click segment in the site overlay showed that placing the link more prominently on the webpage decreased the overall time it took users to click on it. crazy egg’s main drawback is that archived pages that are no longer tracking click data count toward the overall number of snapshots that can be tracked at one time. if libraries regularly retest a webpage, they will easily reach the maximum number of snapshots their subscription permits in a relatively short period. once a crazy egg subscription is cancelled data stored in the account is no longer accessible. this increases the importance of regularly exporting data. crazy egg is designed to export the heat map and confetti view reports. the direct export function takes a snapshot of the current report as it is displayed, and automatically converts that image into a pdf. exporting the heat map is fairly simple because the report is a single image, but exporting all the content in the confetti view report is more difficult because the report is based on segments of click data. each segment type would have to be exported in a separate pdf report to retain all of the content. in addition, there is no export option for the site overlay report so there is not an easy method to manage that information outside of crazy egg. even if libraries are actively exporting reports from crazy egg, data loss is inevitable. summary and conclusions closely examining in-page analytics, clickheat, and crazyegg reveals that each tool has different levels of click 148

information systems platform through its paces bruce godfrey and rick stoddart information technology and libraries | june 2018 34 bruce godfrey (bgodfrey@uidaho.edu) is gis librarian and rick stoddart (rstoddart@uidaho.edu) is education librarian at the university of idaho library. abstract web geographic information system (gis) platforms have matured to a point where they offer attractive capabilities for collecting, analyzing, sharing, and visualizing in-library use data for space-assessment initiatives. as these platforms continue to evolve, it is reasonable to conclude that enhancements to these platforms will not only offer librarians more opportunities to collect in-library use data to inform the use of physical space in their buildings, but also that they will potentially provide opportunities to more easily share database schemas for defining learning spaces and observations associated with those spaces. this article proposes using web gis, as opposed to traditional desktop gis, as an approach for collecting, managing, documenting, analyzing, visualizing, and sharing in-library use data and goes on to highlight the process for utilizing the esri arcgis online platform for a pilot project by an academic library for this purpose. introduction a geographic information system (gis) is a computer program for working with geographic data. a gis is an ideal tool for capturing data about library learning spaces because they can be described by a geographic area. the learning spaces might be small or large, irregularly shaped or symmetrical—either way, the shape can be described by a set of geographic coordinates. tools for storing, managing, documenting, analyzing, and visualizing geographic data can all be found in a gis. the locations and shapes of geographic features (such as library learning spaces) as well as attributes of those features (such as the type of learning space) can be captured in a gis. the roots of giss stretch back to the 1960s. goodchild characterizes giss’ advances in spatial analysis during the 1970s and the growth of gis in the 1980s, coinciding with the proliferation and affordability of desktop computers.1 the enhancement of gis software from desktop computer applications to online platforms has been underway for some time. the origins of web gis can be traced back to 1990s, but it is only since the mid2000s that products have really matured to a point where they can be viable alternatives to their desktop counterparts. web gis first appears in 1993 when xerox corporation’s palo alto research center created an online map viewer.2 their map viewer, running in a web browser, was the first demonstration of performing gis tasks without gis software installed on a local computer. even though this early web-based gis application had limited capabilities, the potential of performing gis operations from computers anywhere and anytime was recognized. the possible capabilities of web gis began to be more fully discussed in the mid-1990s.3 web gis software became available in earnest in 1996 as gis companies began releasing commercial offerings.4 the first two decades of this century have seen web gis explode in functionality and scope to become an integral part of most giss. mailto:bgodfrey@uidaho.edu mailto:rstoddart@uidaho.edu managing in-library use data | godfrey and stoddart 35 https://doi.org/10.6017/ital.v37i2.10208 in late 2012, a collaborative mapping platform hosted by esri (environmental systems research institute) named arcgis online (https://www.arcgis.com/) was released. esri is a gis software company that was founded in 1969, and its products are used by more than 7,000 colleges and universities across the globe.5 the collaborative platform enables users to create, manage, analyze, store, and share maps, applications, and data on the internet. gis software continues to evolve from desktop computer programs to specialized software applications (i.e., apps) that are part of a web-focused platform. this transformation is profoundly growing the accessibility of the technology to a broader array of users. what was once a technology reserved for geographic information professionals because of its complexity and cost has now been streamlined and put in the hands of nonprofessionals who want to take advantage of its many possibilities. it is no longer reserved for academic disciplines such as geographic information science and remote sensing science; instead, gis has seen its use grow in humanities and social science to the point where libraries are developing targeted services for these disciplines. 6 professionals are afforded the ability to share their data more easily, and nonprofessionals are able to utilize those data to create information and knowledge more easily. this transformation bodes well for libraries because it lowers technological hurdles that might have precluded the technology’s use for space-assessment and other place-based initiatives in the past. now that software-as-a-service (saas) mapping platforms such as mango, gis cloud, and arcgis online enable users to access capabilities over the internet, there is no server software for users to install or licensing to configure. additionally, the training required by personnel to gather, utilize, and manage data has been greatly reduced compared to its desktop predecessor. academic libraries, and libraries in general, stand to gain from the evolution. the use of desktop gis for space assessment the value of space planning efforts in libraries and the observational methods employed to conduct such activities have been well articulated in library research. the use of desktop gis as a tool for collecting in library use data in academic libraries has been present for more than a decade. bishop and mandel show that libraries’ use of gis falls into two broad categories, analyzing service area populations and facilities management, the latter of which encompasses “in-library use and occupancy of library study space.”7 work related to the use of gis to study library-patron spaces is discussed below. in the past twenty years, academic libraries have seen many transformations in their roles on college and university campuses. gis technologies have helped document and respond to those transformations. xia outlined the value of using gis as a tool for space management in academic libraries more than a decade ago because of its “capacity for analyzing spatial data and interactive information.” 8 in one study, xia describes using esri arcview 3.x desktop software for library space management. arcview was esri’s first gis software to have a graphical user interface; predecessors had command-line interfaces. xia mentions the use of, at that time, the emerging arcgis product, which went on to replace arcview 3.x. gis proved to be a valuable tool for xia to track the spatial distribution of books in the library environment.9 xia went on to measure and visualize the occupancy of study space using arcview.10 lastly, xia used arcview as an item-locating system within the physical space of the library.11 more recently, mandel utilized mapwindow, an open-source desktop gis originally developed at idaho state university, for creating maps of fictional in-library use data.12 mandel’s process demonstrated how a gis could be utilized to visualize the use of library spaces for marketing materials and services as well as graphically depicting a library’s value. coyle argued for the use of gis as a tool to analyze the interior space of the library, and specifically the library collection itself, while not implementing a system with any https://www.arcgis.com/ information technology and libraries | june 2018 36 specific gis package.13 given and archibald detailed their use of visual traffic sweeps as an approach to collect and visualize in-library use data.14 their workflow involved utilizing a microsoft excel spreadsheet to capture data and then importing the data into arcgis to query and visualize the data. therefore, gis wasn’t used for data capture; it was used toward the end of the process to visualize these data. while the body of work details the use of desktop gis for working with in-library use data, collaborative web gis platforms now offer opportunities to advance existing research in this arena by streamlining datacollection workflows, sharing database schemas, and enabling broader collaboration with peers, thereby potentially creating opportunities for new research. fusing the capabilities of these new platforms with traditional observational methods of gathering data on how people are using library spaces extends the body of knowledge and offers interesting new opportunities for research such as cross-institutional comparisons. it is critical for twenty-first-century academic libraries to collect such data to continue to evolve with the changing needs of digital-age campus research and culture. utilizing a cloud-based platform for learning space assessment discussed below is the approach employed for this pilot project to use web gis to collect, manage, share, and visualize information about library learning spaces. this pilot project utilized the esri arcgis online platform and client applications accessing that platform (see figure 1). collector for arcgis (http://doc.arcgis.com/en/collector), a ready-made app, was used for data collection. arcgis desktop (http://desktop.arcgis.com) was used at the outset to create the initial database schema. a custom html/javascript web application was developed to better enable library administrators to visualize the data as a map, table, or chart. prior to the implementation of this pilot project, the circulation department conducted floor sweeps for safety purposes (e.g., making sure certain doors were locked), but space assessment data had never been gathered for the library. research study location all observations were taken during fall 2016 and spring 2017 at the university of idaho library and the gary strong curriculum center. this article focuses on the implementation of the platform for use at the library. the first floor of the university of idaho library underwent a remodel during winter 2016. the remodel included new furniture and different configurations of areas better customized for learning and studying. spaces such as group study, booths, and brainstorming spaces figured prominently in the remodel. additionally, expanded food and beverage options and having proximity to open seating areas located near natural light provide a welcoming environment. library hours were also expanded to 24 hours per day, 5 days a week. with these changes arose the desire to digitally collect data to learn about the use of these new locations by patrons. utilizing these data to inform decision-making about future changes to the physical spaces in the library, as well as connecting library learning spaces to campus learning outcomes, were goals of this research. http://doc.arcgis.com/en/collector http://desktop.arcgis.com/ managing

resources to implement this pilot project was a requirement. funding was not available to purchase server software or hardware. personnel time could be carved out of existing positions for this effort, but money was not available to hire additional personnel. the university of idaho library does not have a dedicated it unit, so choices were limited. purchasing business-intelligence software such as tableau was cost prohibitive. an open-source tool such as suma, developed by north carolina state university libraries, was not a practical option in this case because the system requirements did not align with the expertise of existing personnel.15 fortunately, the arcgis online platform was available for this research at no cost to the library, and existing personnel had experience using the platform. the university of idaho participates in, and contributes financially to, a state of idaho higher education site license for esri software. the software is then available to personnel across the institution for research, teaching, and, to a lesser extent at this time, administrative purposes. since arcgis online is a cloud platform, there is no server software to install and update and no server hardware to configure. additionally, the university of idaho gis librarian was familiar with the capabilities of the platform and available to actively participate in this research. information technology and libraries | june 2018 38 in short, researchers’ access to and existing expertise with the arcgis online platform, coupled with the extensive capabilities of the platform itself, made it the best choice for this research. pilot project design a public services librarian and the gis librarian assumed leadership roles for the pilot project. the public services librarian led tasks associated with defining the learning (i.e., the data-collection) spaces, defining the data fields and domains for those spaces, and overseeing personnel responsible for collecting these data. the gis librarian led tasks associated with creating the database schema, creating the geographic features representing the learning spaces, creating a web application to visualize the data, and managing content on the arcgis online platform. library personnel were responsible for collecting the data. gathering ancillary data having building floor plans in a digital format was helpful for data collectors to orient themselves in the space when looking at a map on a mobile device. our research team was able to acquire georeferenced building floor plans for our institution from the information technology services unit on campus. each of the four floors of the library were published to arcgis online as hosted tile layers to serve as a frame of reference for data collectors. managing content and users arcgis online provides the ability to create and define groups. groups are collections of items that can be shared among named users. individual user accounts for each project participant were created, and a group containing items for this pilot project to be shared among those users was created. this approach allowed all data associated with the project to be private and only shared among personnel participating in the project. database design the primary knowledge product resulting from this research was a web application containing a twodimensional map, tables, and charts. a geodatabase, which is an assemblage of geographic datasets, needed to be designed and created to provide data to the web application.16 designing a geodatabase begins with defining the operational layers required to gather information. 17 for this pilot project, one operational layer depicting individual learning spaces was required (see table 1). table 1. description of the learning spaces layer layer learning spaces map use learning spaces define areas intended for a specific type of learning data source digitized using building floor plans as a frame of reference representation polygons the learning spaces layer was used to store the geometry of the individual learning spaces. a table to store observations for each learning space was needed, and a relationship between each individual space and the observations for each space was required (see figure 2). the relationship binds observations to their appropriate learning spaces. the relationship was defined to allow one learning space to relate to many observations for that space. managing in-library use data | godfrey and stoddart 39 https://doi.org/10.6017/ital.v37i2.10208 figure 2. data elements of the geodatabase. fields, analogous to columns in a spreadsheet, were defined for the learning spaces and observations table to store descriptive information. for example, a friendly name was assigned to each learning space. additionally, domains were defined to manage valid values for specific fields. domains were necessary for quality control and quality assurance to enforce data integrity, enabling data collectors to pick items from lists rather than having to type the item names. this feature eliminates potential data-collection errors. field names, data types, field descriptions, and domains for this pilot project can be found in the appendix. defining data-collection spaces a template was created to define the information required to create each learning space feature. these features were created by digitizing them on a computer screen for each of the four floors of the library using the building floor plans as a frame of reference. ten learning spaces were defined for the first floor of the library and one each for floors 2, 3, and 4. a map for each floor was created and published to arcgis online as a hosted feature layer.18 each map contained two layers: one for the floor plan and one for the learning spaces (figure 3). library personnel used these maps to collect data. data collection data collection was accomplished using collector for arcgis installed on mobile devices. this eliminated the need for any software-development costs for data collection. collector for arcgis is a ready-made arcgis online application that is designed to provide an easy-to-use interface for collecting location-based data. the software was installed on a variety of devices, including a samsung galaxy tablet, a surface tablet, and an apple ipad. the online collection mode was enabled during collection, resulting in data being transferred real-time to arcgis online. the software can collect data in an offline mode, but, because strong internet connections were available in both campus buildings, the online mode was utilized. the collection workflow consisted of library personnel traversing the floors of the library and recording data about the number of users in each space, what the users were doing in the space, and entering additional context comments if necessary. library staff were encouraged to use their own expertise and observational cues (e.g., textbooks present) when recording data associated with patron activities in library spaces. the date, time, and name of the data collector was recorded automatically, an option available through the arcgis online platform. the user interface for the software was friendly and intuitive and required minimal training (figure 4). a list was provided to select the type of use for the selected space. data were accessible via arcgis online immediately following collection. information technology and libraries | june 2018 40 figure 3. first floor learning spaces of the

https://doi.org/10.6017/ital.v37i2.10208 results of using web gis web gis, specifically arcgis online, offered the functionality required for collecting and managing in library use data. additionally, the platform offers librarians supplementary opportunities for collaborative space-assessment projects. while the arcgis online platform proved to be useful for this pilot project, some of the advantages and limitations encountered are discussed below. advantage: ease of use through targeted applications esri software has been used in academia for decades. while the early command-line versions and later desktop versions were the playground of those with gis training, web gis applications have a decidedly friendlier interface because of the ability to customize applications on the platform for specific purposes. for example, applications with management functionality can be separated from applications intended for data gathering. the need for excessive functionally to be included in one interface is replaced with a more modular framework, resulting in less complex user interfaces as seen in many desktop gis programs. while some personnel involved with this project had used esri software for many years and were familiar with the capabilities of the arcgis online, they had not used the platform for data collection prior to this project. managing users and content for the project proved to be straightforward. it was made even easier when enterprise logins were configured, which allowed personnel to sign in using their institutional user name and password. authoring the database schema, creating the necessary maps, and publishing those maps as hosted services was not complicated for those with basic desktop and web gis knowledge. those responsible for collecting data needed little training using collector for arcgis to begin data collection. finally, librarians with no gis background were able to export the data to a familiar format (commaseparated values) to begin analysis using software such as excel. in short, authoring the database and map services remains best handled by those with gis experience. however, targeted application interfaces enable user without gis experience to collect and work with data. advantage: participation in enterprise architecture conducting library research on a platform many faculty, students, and staff are beginning to use for research, learning, and administration places librarians within the same collaborative space as the communities they are serving. in the case of this research, our need for building floor plans presented opportunities to more broadly discuss enterprise gis at our institution by sharing this information. interaction took place between the library, facilities services, and information technology services, resulting in a cultivation of relationships around data sharing. furthermore, integration of our enterprise security with the arcgis online platform adds a level of legitimacy to geospatial data management efforts. advantage: potential for cross-institutional collaborative projects the potential for cross-institutional collaboration on library-space assessment and other projects should not be overlooked when using the arcgis online platform. such collaborations are even more manageable because esri software is being used by more than 7,000 colleges and universities across the globe. even though cross-institutional collaboration was not a goal of this research, the opportunities for projects or programs of this nature became abundantly clear. items created in arcgis online can be shared between organizations. simply sharing a library-space-assessment database schema with librarians at other institutions would allow them to quickly implement a similar project on the arcgis online platform. this opens the door to new research opportunities. the functionality exists for one institution to host a database that personnel from multiple institutions could populate. a single dataset containing learning spaces of multiple institutions with multiple contributors could be created, managed, and analyzed collaboratively. this could enable lower-resource libraries to participate in projects with larger institutions as economies information technology and libraries | june 2018 42 of scale are realized. and it offers the ability to undertake projects across multiple institutions to explore broader space assessment or other research questions. limitation: updating hosted feature service schemas the ability to author and edit schemas entirely in arcgis online has not yet matured to a point where it matches the abilities of its desktop counterpart. specifically, updating a published schema is currently difficult to accomplish in arcgis online because a user-friendly interface does not exist. however, the task can be accomplished by editing the javascript object notation (json) of the hosted feature service. while this is a current limitation for managers of the hosted feature service and not data collectors, it is anticipated that this will be addressed in future updates. limitation: user interface for standards-based metadata items created as part of the pilot project were documented using the metadata editor provided in arcgis online. arcgis online’s users can create and maintain geospatial standards-based metadata for content. however, the user interface for creating metadata based on either the iso 19115-series or federal geographic data committee (fgdc) content standard for digital geospatial metadata (csdgm) could be improved by simplifying its complexity and allowing for batch updating specific elements. item documentation for the platform focuses on creating and editing elements of arcgis-format metadata. it should be noted, and potentially added as a point of concern for librarians, that the ability to author and edit metadata based on the iso and csdgm standards was introduced three years after the initial release of arcgis online. limitation: visualizing data in related tables the ability to visualize data collected as part of this project using ready-made applications in arcgis online yielded unsatisfactory results. the primary limitation was related to working with repeated measurements for the learning spaces. ready-made applications like web appbuilder and operations dashboard have limited support for a user-friendly presentation of repeated learning-space observation. therefore, a custom web application was developed by a university of idaho student using the esri javascript application programming interface (api). the application provides the ability to select a date range, a time scope (e.g., daytime, nighttime, all hours), a building, and a floor to visualize the data. the learning spaces are colored by the total number of users in a space on the basis of the parameters selected (see figure 5). figure 5. map view of the space assessment dashboard application. managing in-library use data | godfrey and stoddart 43 https://doi.org/10.6017/ital.v37i2.10208 for each individual space, a chart and table can be displayed to gain further insight (see figures 5 and 6). figure 6. chart view of the space assessment dashboard application. figure 7. table view of the space assessment dashboard application. limitations: data-collection software issues using collector for arcgis on devices running windows 10 proved frustrating because of a documented bug with collector. a “you are not connected to the internet” error would appear randomly, even when there was a valid internet connection. a workaround was implemented to circumvent the issue, but it was a source of frustration for data-collection staff. offline data-collection mode was experimented with to see if it was a more favorable option; however, the date and time of the data collection are not captured in offline information technology and libraries | june 2018 44 mode, so that potential workflow was abandoned. there were no issues encountered for data collectors who used the samsung galaxy (running the android operating system) or an apple ipad. conclusions web-based gis platforms such as arcgis online have evolved to the point where they offer the functionality required for collecting and managing in-library use data. the arcgis online platform performed commendably for this pilot project. while arcgis desktop was used to author the original database schema in this project, it is reasonable to conclude that it is only a matter of time until the functionality required to complete the entire workflow in the web-based platform is available. using mobile and desktop devices outfitted with the collector for arcgis application proved to be a practical way for collecting real-time in-library use data. managing project users and the items those users were able to access was straightforward. while the visualization tools for repeated measurements data are currently limited in arcgis online, the data are accessible as a web service, and the sky is the limit on custom webapplication development. looking ahead, adjusting schemas to capture height above and below ground level to take advantage of 3d data models and visualization is intriguing. use of this model may be beneficial for space-assessment projects that seek to gather data more broadly across institutions. finally, a noteworthy realization from this research is the potential for inter-institutional and crossinstitution collaboration of library space–assessment projects, or other projects for that matter. librarians can begin embracing the web gis movement alongside those in the communities they participate in and serve. opportunities to create efficiencies are possible through the simple sharing of database schemas. additionally, the ability for one institution to host a database enabling personnel at multiple institutions, or at multiple libraries at larger institutions, to contribute data is available and ready for further research. managing in-library use data | godfrey and stoddart 45

information science that brings order and proper management to the holdings of a library. compared to printed media, digital collections present numerous challenges regarding their preservation, curation, organization and resource discovery & access. therefore, true native perspective is needed to be adopted for bibliographic classification in digital environments. in this research article, we have investigated and reported different approaches to bibliographic classification of digital collections. the article also contributes two evaluation frameworks that evaluate the existing classification schemes and systems. the article presents a bird’s-eye view for researchers in reaching a generalized and holistic approach towards bibliographic classification research, where new research avenues have been identified. introduction classification is the primary instinct of human beings in arranging, understanding, and relating knowledge artifacts. bibliographic classification provides a framework for arranging and organizing knowledge artifacts preserved in the form of books, magazines, newspapers and other holdings to explore new avenues of knowledge management. today several classification schemes are in use ranging from conventional classification schemes including library of congress classification (lcc), dewey decimal classification (ddc), colon classification (cc), and universal decimal classification (udc) to classification for digital environments including association for computing machinery (acm) digital library1, institute of electrical and electronics engineering (ieee) digital library2, and online computer library center (oclc) cooperative catalogue3. besides the difficulties that lie in devising a classification scheme (time-consuming and resourceconsuming), it is required that either the existing schemes should be revised and extended or a new classification scheme should be devised, which could act as a common platform for representing knowledge artifacts belonging to different contexts. such a classification scheme should also resolve the challenges in digital preservation and curation and support the precise asim

doi:10.6017/ital.v36i3.8930 49 and accurate search and retrieval of digital collections. the first step, in this connection, is to properly analyze and evaluate the existing bibliographic classification schemes and to dig out their strengths and limitations in classifying digital collections accurately and appropriately. therefore, the objectives of this research article include: • to investigate and evaluate the available approaches to bibliographic classification from the perspective of devising a classification scheme that can act as a common platform for classifying any type of digital collection. • to devise evaluation frameworks that compares the available bibliographic classification schemes and approaches. • to present issues, challenges, and research opportunities in state-of-the-art bibliographic classification research. the rest of the paper is organized as: section 2 presents the current trends in the classification of digital collections. section 3 presents two evaluation frameworks for comparing and evaluating the existing solutions. section 4 presents research challenges and opportunities in bibliographic classification research. finally, section 5 concludes our discussion. references are presented at the end of the paper. classifying digital collections – a mixed trend the bibliographic classification has been the focus of several researchers to properly classify, catalogue, and describe digital collections. in this regard, two approaches have been adopted: the former supports the use of conventional classification schemes including cc, ddc, and lcc etc., in describing and classifying digital documents, while the latter recommends devising some new ways of classification such as acm4 computing classification. however, in most of the digital environments, a mixed trend has been observed, where along with new classification schemes, categorization is also used as a complementary solution. for example, acm presents its own classification system as poly-hierarchical ontology in describing computer science literature and for using in semantic web applications. acm has replaced its 2008 acm classification system that serves as de-facto model for the classification of computer science literature by giving visual topic display along with searching services. it serves as semantic vocabulary for categorizing concepts and a foundation of computing disciplines ("the 2012 acm computing classification system,"). similarly, ieee digital library categorizes its holdings into directories per its own rules of cataloguing and categorization. it categorizes articles and standards in to several subject areas and clusters documents through year of publication, author names, content type, affiliation, publication title, publisher, country of publication, alphabets, numerals and alphanumeric values5. the document collection can be navigated through collection names, number of documents, by topic and international classification for standards (ics). 4 http://dl.acm.org 5 http://ieeexplore.ieee.org/browse/standards/ics/ieee/ information technology and libraries | september 2017 50 the dmoz6 directory is the largest human made directory of web pages. since its inception in 1998, it categorizes 3,861,137 websites available in 90 languages into 1,031,719 categories and sub-categories by 91,928 editors and volunteers. in addition, it has its dmoz rdf dumps available on linked open data (lod) cloud. according to the world wide web consortium (w3c), lod enables the data integration and reasoning at a large scale ("linked data,"). it establishes links among data enabling machines and users to explore the web of data rather than the web of documents along with finding related data (berners-lee, 2006; bizer, heath, & berners-lee, 2009). however, it lacks in semantic search (meaningful search), which affects the precision and accuracy in exploring the required resources. also, the categories, under which the websites are kept, are needed to be revised because there can be faceted and intra-hierarchical links among web pages. in addition, the content management needs to be upgraded for updating the directory with new entries and the way it reviews and categorizes websites (boykin, 2016). institutional repositories use the mixed approach towards creating, collecting and managing metadata for printed and digital collections using several sources including conventional and digital. this mixed trend introduces challenges to the metadata managers (chapman, reynolds, & shreeves, 2009). to deal with these challenges, the subject classification systems can be very beneficial in providing web-oriented services including searching of contents through search patterns, browsing, and content filtering by subject area. however, at the same time, a cognitive overload rises for the authors and depositors of the institutional repository (cliff, 2008) that needs further attention. to handle the information overload in retrieving digital collections, several controlled methods have been proposed in the literature ranging from manual techniques (e.g., web directories) to automatic techniques including clustering and classification. several classification schemes including sentiment and subject classification have been developed for classifying (and categorizing) web pages. classification is used in focused crawling, searching and ranking results, and classifying queries. clustering also classifies web resources but it is slightly different from classification, which is based on a rigid predefined taxonomy and rules for interpreting the meaning of classification order. on the other hand, clustering shows flexibility in classification (categorization) of web documents (zhu, 2011). however, a mixed trend has been observed, where classification and categorization are intermingled to facilitate organization, description, exploration, and retrieval of digital collections. semantic web brings meaningful connections between the web of data so that not only humans but machines can also understand the content of documents to retrieve the most intended and required documents. this way other related documents could also be easily connected and retrieved (berners-lee, 2006). to understand, describe, and relate concepts within documents, ontologies are used. therefore, researchers have been working on bringing semantics through semantic web and related technologies to automatically classify digital collections. for example, 6http://www.dmoz.org bibliographic classification in the digital age | ullah, khusro, and ullah | doi:10.6017/ital.v36i3.8930 51 (beghtol, 1986) argues that semantic axis makes syntactical classification structure more meaningful and provides the platform for developing relationships among knowledge artifacts through several warrants in classification systems. similarly, classification ontology is used in automatic classification (wijewickrema & gamage, 2013) to minimize the ambiguity in vocabulary. to obtain a single subject for the input document, several weight functions including the term frequency-inverse document frequency (tf-idf), and filtering methods are applied. semantic web and lod technologies have also been used in dealing with bibliographic data. for example, bibbase7, a bibliographic data publishing and management tool (xin, hassanzadeh, fritz, sohrabi, & miller, 2013) publishes bibliographic data on the user website according to lod principles. however, these are limited because of the lack of interoperability among native languages while translating classification records from source language to the target language (kwaśnik & rubin, 2003). the classification schemes are also being converted into ontologies. (giunchiglia, marchese, & zaihrayeu, 2007) have applied reasoning capabilities of owl ontologies to classification schemes. these ontologies are used as interfaces to human knowledge for machines whereas classification schemes are interfaces to knowledge for humans. however, there is limited support available for cross-disciplinary searching and accommodation for more views and interpretations of knowledge (albrechtsen, 2000). the supervised and unsupervised machine learning techniques are used for automatic text classification. supervised machine learning techniques use models including multinomial naïve bayes model, and bernoulli model (manning, raghavan, & schütze, 2008) for classification. yelton (2011) applies probabilistic classification of important words (and therefore of documents) especially by considering amazon’s statistically improbable phrases (sips)8 and google phrase search inside a book. for subject analysis, he mentions simplistic; content-based; and requirements-based methods in terms of understanding text classification and manipulation of books. the wikipedia page structural hierarchy is exploited in automatically harvesting, classification, categorization, clustering, and metadata enrichment (yelton, 2011). information extraction (ie) is also applied in classifying books automatically. for example, (betts, milosavljevic, & oberlander, 2007) use ie methods for automatic labeling of books using lcc classification. they used bag-of-words (bow) model, bag-of-named-entity recognition (ner) model, generalizing named entities (gaz) model in automatic text classification. to achieve better accuracy, they also combined the results of these models. however automatic classification may lead to limited search and retrieval because of the missing semantics associated with phrases or key words. to overcome this issue, a fundamental and practical theoretical model of classification is required (jones, 1970). 7 https://bibbase.org/ 8http://www.amazon.com/gp/search-inside/sipshelp.html information technology and libraries | september 2017 52 table 1 categorizes the bibliographic classification approaches into three broader categories namely: theoretical approaches, practical approaches and approaches used in digital environments. theoretically researchers have discussed different viewpoints for classification, whereas we get a different view when these schemes are applied for classification. practically, the syntactic structure is valued by using faceted and enumerative techniques. in digital environments like the web and digital libraries, strict boundaries of classification are often compromised by categorization. approaches to classification techniques used theoretical approaches 1. biasness (mai, 2009) (mai, 2010) 2. subjectivity and objectivity (hjørland, 2016) 3. epistemological and semiotic approaches (hjørland, 2013) (lee, 2012; mai, 2011) (tennis, 2008) 4. empiricism, rationalism, historicism and pragmatism (hjørland, 2013) 5. multidisciplinarity approach (beghtol, 1998) 6. scientific approaches (hjørland, 2008) 7. positivistic and pragmatic approaches (dousa, 2009) (mai, 2011) 8. interdisciplinary and evidence based practice classification (hjørland, 2016) 9. social and cultural context (j.-e. mai, 2004) 10. by tracking the universe of knowledge 11. universal order (smiraglia & van den heuvel, 2011) 12. integrative levels in classification (dousa, 2009) 13. literary warrant (rodriguez, 1984) 14. education warrant (hjørland, 2007) (beghtol, 1986) 15. semantic warrant (beghtol, 1986) 16. syntactic warrant (beghtol, 1986) 17. domain and users requirements (mai, 2005) 18. pluralism and human interpretations practical approaches 1. enumerative and faceted (batley, 2014). 2. general purpose approach (mai, 2003) and special purpose approach (mancuso, 1994) e.g. classification schemes for general classes of knowledge areas or for a special class of knowledge area. 3. syntactic axis (beghtol, 1986) (beghtol, 2001) 4. semantic axis (beghtol, 1986) (beghtol, 2001) bibliographic classification in the digital age | ullah, khusro, and ullah | doi:10.6017/ital.v36i3.8930 53 classification in digital environment 1. document similarity (hamming distance and euclidean geometric approaches) (losee, 1993) 2. fuzzy approach (jacob, 2004) 3. clustering (nizamani, memon, & wiil, 2011) 4. categorization (koshman, 1993) 5. tf-idf weighting (dorji et al., 2011) 6. unsupervised machine learning techniques (joorabchi & mahdi, 2011).

towards bibliographic classification evaluating classification schemes & approaches in this section, we present two evaluation frameworks to compare and evaluate the existing classification and categorization systems and well-known bibliographic classification ontologies. we have chosen cc, ddc, lcc, and universal decimal classification (udc) on the basis of their structural properties and wide usage both in conventional and digital libraries ("subject classification schemes," 2015) ("library of congress classification," 2014) ("about universal decimal classification (udc),") (press, 2002) (encyclopedia, 1 august 2014). some of these properties include: citation and filling order; notations expressiveness; flexibility in classification principles, rules and notations; coverage of the knowledge areas; classification schedules and notations structure; notations brevity and simplicity; notations mnemonics; notations hospitality; schedules with updateable and comprehensive subjects order; and knowledge coverage (batley, 2014). the udc, lcc, and ddc are universal, multidisciplinary, and widely used systems (koch & day, 1997), whereas cc has the seminal and inspirational value for the faceted structure of the bibliographic classification. therefore, the evaluation framework mainly targets these classification schemes as our natural choice for the evaluation and comparison. similarly, we evaluate acm9, ieee10 and dmoz11 using the evaluation framework as these are the well-known and widely used document classification & categorization systems for the digital

notations in classifying and describing a specific subject area. the metric will help us in selecting a classification scheme or system that is easy to use in classifying document collection by requiring short notations and simple rules. the notations and rules are complex in cc and udc (ranganathan, 1968). this complexity is because of the faceted structure in these classification schemes (sukhmaneva, 1970). the structural complexity of cc is greater than that of udc. udc comes at second position in complexity as compared to cc. because of its enumerative structure, lcc stands at third position, as it is lesser complex than cc and udc. ddc is the simplest in this list because it is based on enumerative classification structure and on the principle of dividing universe of knowledge into defined classes. ieee is more complex than acm, whereas dmoz is the least complex system. the classification system with greater structural complexity is ranked lower in the list. therefore, based on this metric, the classification systems can be ranked as dmoz, acm, ieee, ddc, lcc, udc, and cc. the notational brevity means how brief are the notations in describing and understanding the holdings with minimum number of symbols and minimal cognitive load. ddc uses well-organized short notations and their mnemonic value is also greater (comaromi & satija, 1983) (hyman, 1980). lcc has notational brevity (chan et al., 2016). udc uses lengthy notations (kaosar, 2008) as compared to ddc, whereas cc also uses lengthy and complex notations (chatterjee, 2016). acm notations are shorter than ieee, whereas dmoz do not use any notations at all. using this metric, these classification systems can be ranked as acm, ieee, ddc, lcc, udc, cc, and dmoz at the last with no usage of symbols at all. the predefined structure means that the classification scheme follows rigid pre-assumed subject categorization along with classification class marks. in this regard, udc and lcc are enumerative information technology and libraries | september 2017 56 and impose subjectivity viewpoint of classification by following a predefined structure (goh, giess, mcmahon, & liu, 2009). being faceted, cc arranges basic concepts in few predefined categories (satija & martínez-ávila, 2015). ddc also has the predefined hierarchical structure of classification (press, 2002) (jonassen, 2004). among these schemes, cc has minimal predefined structure because of using facets; udc is both enumerative and analytico-synthetic. lcc is enumerative but possesses weaker predefined rules for the structural design. because of the rigid enumerative hierarchies and predefined class structure, ddc comes at first position. dmoz has the most rigid predefined structure as compared to that of ieee and acm. the classification system with most rigid and predefined structure is ranked lower, and therefore, the ranking could be cc, acm, ieee, udc, ddc, lcc and dmoz. the complexity in rules determines the difficulty level in applying classification rules on knowledge artifacts. cc presents a complex set of rules and classification theory, which is comparatively difficult to implement and understand (tennis, 2011). lcc is also complex ("library of congress subject headings: prevs. post-coordination and related issues," march 15, 2007 ) in implementing library of congress subject headings (lcsh) in pre-coordinated subject strings. ddc’s rules and principles are comprehensive and complete (press, 2002) and easier than those of cc and lcc. udc is also easy to understand and implement (piros, 2014). acm, ieee, and dmoz are simple to use and understand, and therefore, bears no such complexity. a classification system with greater complexity is ranked lower, therefore, based on this metric, the rankings could be acm, ieee, dmoz are on top with similar rankings followed by udc, ddc, lcc, and cc. theoretical laws are considered as a metric to analyze the foundations of classification systems to understand whether they are based on certain theoretical laws and principles of classification or not. udc combines the enumerative and faceted approaches gathered from ddc and cc (kaosar, 2008). the synthetic principle of udc contributes to its widespread use but it is not enough at the intellectual level for making the relations between the subject facets (kyle & vickery, 1961). udc lacks standard rules for its application for making facets, but there are rules for its structural representation (mcilwaine, 1997). therefore, the structural and synthetic rules are good enough for its applicability but it should be refined further at the intellectual level. the theoretical laws of cc are based on the faceted approach of managing knowledge artifacts. cc has sound rules and principles, which include different postulates, laws, principles and canons (batley, 2014) (arashanapalai neelameghan & parthasarathy, 1997). on the other hand, lcc has weaker theoretical foundations. there also exists some intellectual and structural limitations due to its enumerative structure (san segundo manuel, 2008). ddc has the hierarchical and the enumerative structure which is based on the knowledge philosophy of hierarchical division (hjorland, 1999). because of the strong theoretical foundations, cc is at the top of this list, ddc is second because of its universal theory of knowledge division, udc is third for being exploiting the theories of ddc and cc, lcc is at fourth position for comparatively weak theory of classification, whereas acm, ieee, and dmoz present no or very limited theoretical laws or philosophical rules of classification. bibliographic classification in the digital age | ullah, khusro, and ullah | doi:10.6017/ital.v36i3.8930 57 the support for using mnemonics enables human classifiers to easily memorize the symbols and notations of classification scheme. the systematic and literal mnemonics are used in udc (satija, 2013) (kaosar, 2008). the mnemonics are increased through mnemonic devices, which are described through the canons of mnemonics (kaula, 1965). lcc uses literal mnemonics (satija, 2013), whereas ddc uses systematic and literal mnemonics but its systematic mnemonics are not consistent (satija, 2013). there are several seminal mnemonics in cc (rahman & ranganathan, 1962). these mnemonic devices increase mnemonics in cc, but the formation and length of the notations affects this mnemonic quality. acm has greater support for mnemonics in comparison with ieee, whereas dmoz is the collection of web pages under specific categories. based on this metric, the rankings of classification systems could be ddc, udc, lcc, acm, ieee, cc, whereas dmoz lacks in using any mnemonic devices or notations. hospitality means the ability of a classification scheme to incorporate new knowledge areas expressed in different multilingual contexts. hospitality is present in udc (kaosar, 2008). cc is also hospitable for new subjects (de grolier, 1962). lcc is hospitable for expressing the new subjects and knowledge areas (satija, 2013). ddc is hospitable for new subject areas (satija, 2013). by applying this metric, a classification scheme with faceted approach is naturally more hospitable than others. therefore, cc is more hospitable and at the top in this list followed by udc. ddc is at third position for being following enumerative approach. lcc is at fourth position because of it’s of pure enumerative structure. ieee and acm are at fifth position by covering short span of knowledge areas, faceted structure, and efficient search. dmoz is covering only web pages in already specified categories therefore it is at seventh position. search complexity measures the difficulty in searching artifacts using a classification scheme. it describes that which classification scheme is worth in searching a specific document. search complexity is minimal in udc because of its syntactic-analytico and enumerative nature (kaosar, 2008), which can contribute in search applications in both web based and in-house searching applications e.g., online public access catalog (opac). the theory and philosophy of cc is the trend setter for the knowledge management, resource discovery & access, however, according to (raghavan, 2016) searching through cc is comparatively weaker than other bibliographic classification schemes. according to (chan, 2000), lcc and lcsh have the potential to provide the ease in searching because of richer vocabulary for greater subject coverage, synonym and homograph capabilities, pre-coordinated system, browsing capability in multi-faceted structure, multilingual support and marc format support with sematic interoperability. however, it is limited in providing ease in search & retrieval process, which include syntax and application rules complexity, lack of training for the personnel, and too lengthy and complex searching strings. ddc and lcc are aggregated in classify12 project initiated by oclc. with the use of the classify application, the search experience of the catalogers and patrons becomes much easier. using this metric, ddc stands at the top with least complexity than lcc, udc, and cc. ieee is more complex than acm and dmoz. the classification scheme with less search complexity will be ranked higher. 12 http://www.oclc.org/research/themes/data-science/classify.html information technology and libraries | september 2017 58 therefore, acm and ieee, ddc, and lcc stand first with least search complexity followed by udc, and cc. dmoz stands at the last position with greater search complexity having loose boundaries of categorization. usability analyzes the difficulty in using a classification scheme for classifying and searching documents. this metric defines the ease of learning and effective usage. usability measures user satisfaction, user understanding of the system, and precision with minimal recall in lesser amount of time (singapore, 2016). oclc has included structural changes to improve usability and simplify classification tasks ("dewey services: dewey decimal classification system,"). the classify13 project aims at finding books through a web interface, which is easy to use and understand by using ddc and lcc. udc is extensively used in web-based search and retrieval applications (kaosar, 2008). this classification scheme is used in several institutions’ opac systems ("library opacs containing udc codes,"). the udc notations are supportive for the usability (slavicoverfield, 2005). however, the user interface of these opac search systems could be further improved (slavic, 2006) (pollitt, 1998) (schallier, 2005). cc is the source of inspiration and a standardized model for the usability of faceted structure of bibliographic classification in the electronic and web based environments (thelwall, 2009). in (rosenfeld & morville, 2002), the philosophy and methodology of cc is considered at the abstract and theoretical level. this assessment of cc leads us to the argument that the faceted structure is supportive in precise retrieval with a considerably high cognitive work at the user end as compared to ddc and lcc because of their simple enumerative structures. library of congress uses lcc in its catalog14 and classification web15 applications. these applications are exploiting lcshs and lcc in user friendly manner. by looking at the usability aspect of these classification schemes, the ranking through this metrics appears as ddc is at the top for its easy enumerative structure and notational simplicity along with easy to use web applications. lcc is at second position because of its enumerative structure and adoptability in web applications. being enumerative and faceted, udc stands at the third position. cc for being a pure faceted scheme with complex notations and rules, is ranked at the fourth position. similarly, ieee and acm are faceted and easy to use, and therefore, share the first position with ddc. dmoz with loose boundaries of categorization is least usable with limited browsing and search. the accuracy and precision metric measures how accurate and precise a classification system can identify the exact locations of the holdings in the given knowledge space. udc shows accuracy and precision in finding the required knowledge artifact (kaosar, 2008). the accuracy and precision of cc gets compromised as its lengthy notations introduces complexity in searching and discovering documents (satija, 2015). lcc and ddc were researched for accuracy and precision by using a prototype model (gnoli, pusterla, bendiscioli, & recinella, 2016) for automatic text classification of electronic documents using classification metadata of library holdings from lcc and ddc 13 http://classify.oclc.org/classify2/ 14 https://catalog.loc.gov/vwebv/searchbasic 15 https://www.loc.gov/cds/classweb/classwebfeatures.html bibliographic classification in the digital age | ullah, khusro, and ullah | doi:10.6017/ital.v36i3.8930 59 datasets. it was observed that for precision, there is a need for increasing ddc and lcc bibliographic data on the web, introducing searching capabilities for bibliographic data at the micro level of any document, and increasing the efficiency of user interfaces for navigation using ddc-based browsing structure (joorabchi & mahdi, 2009) (joorabchi & mahdi, 2011). therefore, cc because of the pure faceted approach has high-level precision in search and resource discovery. udc stands second because of being enumerative and enumerative and analyticosynthetic. ddc is at the third position as oclc maintains and updates its structure regularly along with state-of-the-art search applications. lcc shares the third position with ddc, being regularly updated and maintained by library of congress for precision in their search application. ieee and acm also show greater precision in their search & retrieval, and therefore, share the third position with ddc and lcc. dmoz are the manually created and updated categories of web pages, having limited keyword search with very low precision. in connection to the evaluation framework, multilinguality means to classify and describe the knowledge artifacts written and expressed in variety of natural languages and the availability of any classification scheme in different natural languages. dmoz supports 72 different languages of the world and therefore stays at the top. udc is multilingual by supporting french, portuguese, spanish and russian (slavic, 2008) (koch & day, 1997) and has been translated into languages ("universal decimal classification summary," 2017). lcc supports works in 19 language subclasses ("library of congress classification outline: class p language and literature,") including german, slavic, oriental languages and roman languages etc. the translations of ddc support to localize this scheme for different languages of the world (vizine-goetz, 2009). ddc is translated in 30 different languages but covers different languages in only seven classes i.e., from 420 to 490 class number ("dewey decimal classification summaries,"). cc shows minimal multilingual support because of its sub-continental origin (a neelameghan & lalitha, 2013; raghavan, 2016). acm and ieee are in english languages only and therefore, show no multilinguality at all. using this metric, we can conclude that dmoz is at the first position, followed by udc, ddc, lcc, and then cc. consistency measures the level of uniformity in classification system to classify subjects. according to (batty, 1967), in the earlier stages, cc shows no consistency but by the addition of consistency cannons, it has gradually become consistent. lcc seems less consistent in expressing different subjects areas (madge, 2011). ddc and lcc were found short of defining and classifying religious holdings especially jewish contents. these schemes also show biasness towards different religious and regional contents (maddaford & briefing). although ddc is a little bit inconsistent, still it can classify complex subjects (gnoli et al., 2016). udc also shows inconsistency, which can be sorted out by introducing specific udc classes to database in online system (kaosar, 2008). ddc shows comparatively greater consistency in classifying new subjects with constant uniformity; cc is ranked second because of the introduction of canons of consistency. lcc and udc are ranked at third position. for being only limited to the scientific research articles, ieee information technology and libraries | september 2017 60 and acm are at fourth position. dmoz stands at fifth position due to its loose boundaries of categorization. the interoperability determines how much a given classification scheme is interoperable in expressing its classification artifacts with other schemes. udc is interoperable (koch & day, 1997) and supports integration with other systems. cc, because of its sub-continental origin, shows limited interoperability (a neelameghan & lalitha, 2013) (raghavan, 2016). lcc shows interoperability by being capable to map with ddc (vizine-goetz, 2009). the interoperability and multilinguality of ddc enables it to map with other classification schemes (vizine-goetz, 2009). ieee, acm and dmoz datasets are interoperable with other web applications. based on this metric, ddc, lcc, udc, acm, ieee and dmoz are standing at first position because of the presence of their interoperability and data harvesting protocols and ontologies in the digital environment. dmoz stands at the second position because of limited interoperability. cc provides only philosophical and theoretical model but we found no practical web-based application so it is not included in this list. by enabling semantic search, a classification scheme can proactively respond to information seekers using its faceted structure. udc, because of its semantic structure (slavic, 2008), contains semantic search capability. the classification theory and philosophy of cc provides the basis for classification ontology development (panigrahi & prasad, 2005), which makes obvious its capability of semantic search and inference. lcc supports semantic search through lod support, semantically enabled lcsh and authority control files ("lc linked data service: authorities and vocabularies,") (harper & tillett, 2007). ddc also contains semantic features (green, 2015), which can be utilized in the semantic search applications. therefore, it can be concluded that semantic search is also supported by ddc. this metric can be better analyzed in the digital environment and especially through analyzing these bibliographic classifications for their ontologies. lcc could be ranked first because of its expressive ontology with efficient semantic search application. ddc is at second position, because of efficient search but limited usage of its ontology. acm is at third position because of its expressive ontology and efficient search but limited coverage to scientific domain. ieee is at fourth position because of its faceted semantic search. udc comes at fifth position because of its ontological presence but with limited usage. cc has no application in the digital environment, which could demonstrate its capability for semantic search, although it provides the basis for the semantic level for all bibliographic classification systems. dmoz lacks in semantic search, where it is only based on keywords. bias in subject representation means inclination for or against some subjects which results in unfair, partial negligence or fully ignoring any subject. ddc and lcc are biased in representing different knowledge and regional information, e.g., anglo-american bias (tomren, 2003), while udc is biased towards european culture (fandino, 2008). cc is biased towards different knowledge areas (satija & singh, 2010). a classification system with least biasness is ranked higher. therefore, in this connection, dmoz is ranked higher for showing no/least biasness; cc is ranked second because of the presence of acute biasness followed by ddc showing comparatively bibliographic classification in the digital age | ullah, khusro, and ullah | doi:10.6017/ital.v36i3.8930 61 less biasness towards religion and regional subjects. lcc comes at the fourth position followed by ieee and acm that show greater biasness towards certain domains. enumerative structure exhibits the rigid hierarchies. lcc is enumerative (goh et al., 2009; perles, 1995) (bryant, october 4, 1993). udc is nearly enumerative and faceted (kaosar, 2008) (bryant, october 4, 1993) and ddc is both analytico-synthetic and enumerative (hallows, 2014). cc is faceted (chatterjee, 2016; dawson, brown, & broughton, 2006). by comparing these systems, lcc fully supports enumerative structure, and then comes ddc, whereas udc is nearly enumerative and cc shows no enumerative structure at all. lcc and ddc are enumerative. the trend is towards semantic and faceted structure, and therefore, enumerative structure in classification systems is not a desirable characteristic. therefore, the system with enumerative nature will be ranked lower. based on this metric, cc and dmoz are least enumerative and therefore, ranked higher, followed by ieee and acm at the second position, then udc at the third position, while ddc and lcc at the last. the faceted structure means the semantically interlinked structure of categories, which can be merged and combined to generate an expression for existing or new concepts (svenonius, 2000). cc is faceted (chatterjee, 2016; dawson et al., 2006). udc is analytico-synthetic (kaosar, 2008) and follows the faceted method of cc using different connecting symbols in mixed notations and using subject facets including time and space (chatterjee, 2016). ieee and acm possess faceted structures. dmoz has only hierarchical structure and predefined categories. based on this metric we rank cc first, udc second, acm and ieee third while ddc and lcc are enumerative structures, and therefore, cannot be included in the list. faceted search means to navigate or browse through the faceted structure of a faceted classification scheme. faceted search is also applied by selecting different ranges and choices from different facets that are given by any faceted system to search the required contents. it is different from search complexity in the sense that it looks at the pattern and criteria of search that exist in any classification scheme either in there opacs or web applications. the theory and philosophy of cc supports faceted search & browsing economically (kong, 2016), however, to the best of our knowledge, no real-world application demonstrates its usefulness. udc is based on the faceted approach, which supports faceted search (tunkelang, 2009). lcc supports faceted search with the help of lcsh (mcgrath, 2007). lcc also provides faceted search through the faceted application of subject terminology (fast) application ("faceted application of subject terminology," 2017). ddc provides the faceted search through the oclc classify16 application. using this metric, these classification schemes can be ranked as ddc at first position because ddc is adopting the faceted approach along with its native enumerative nature and state-of-the-art web based search applications developed by oclc. lcc is at second position because of its web based search applications and its adaptation of comparatively restricted faceted approach. ieee, for providing extensive choice of searching patterns, stands at the third position. acm has poly-hierarchical and 16 http://classify.oclc.org/classify2/ information technology and libraries | september 2017 62 multi-faceted classification structure along with robust search mechanism; therefore, it is on fourth position in this list. there are very limited faceted search applications of udc and therefore it stands at fifth position. dmoz has hierarchical structure in which the required element can be accessed through a keyword search. therefore, it is not providing any faceted search. cc has no search applications that could confirm its support for the faceted search. lod datasets means the availability of datasets of a given classification system on lod cloud. among our choice of well-known classification systems udc, lcc, ddc, ieee, acm and dmoz have datasets in the lod cloud whereas cc has no such datasets. the definitions of classes and properties are gathered in linked data vocabularies (lov), which are used for describing different types of objects used in lod cloud. these definitions of different things provide vocabularies for linking the linked data (foundation, 2017). cc, udc, ddc, lcc, ieee and dmoz have no lov, whereas acm has lov vocabularies. the metric “platforms” in the evaluation framework, considers the applicability of a given classification system in real-world web applications and other digital environments. in this regard, udc is supported by udc consortium, ddc by oclc, lcc by library of congress, acm by acm digital library, ieee by ieee xplore digital library, and dmoz by open directory project. to the best of our knowledge, cc has not been used by any of the online applications. table 3. ranking and average ranking of classification schemes the warrants of classification work as authoritative acts for classificationists to perform the cognitive practice for designing the classes and concepts in the classification system, their structural properties and then putting subjects in the specified classes

literary & scientific warrants. acm and ieee use scientific research warrant, while dmoz exhibits no warrant of classification. in the above paragraphs, we compared and evaluated the selected classification system using the evaluation metrics (shown in table 2), and discussed how these systems can be ranked based on a given evaluation metric. however, to give a holistic view of this comparison and evaluation, we introduce a ranking score or levels ranging from 1 (meaning low ranking, not applicable, or not available) to 7 (meaning high ranking) in how a classification scheme is best among its counterparts in the list. it is also the case that for a given metric, multiple systems may belong to the same ranking level. by assigning these ranking levels, table 3 compares these systems based on 20 metrics by excluding platforms and warrants of classification. table 3 also reports the average ranking of these classification systems, showing ddc at top with average ranking of 3.6, followed by acm = 3.3, and udc = 3.25. it can be concluded that ddc and udc are among the best classification schemes for describing printed as well as digital collections, whereas acm is best for classifying digital collections belonging to computer science domain. however, acm classification system can be extended to include other domains as well. figure 1 illustrates graphically the comparison and evaluation of these systems. figure 1. comparison and ranking of classification systems table 4 presents the state-of-the-art bibliographic classification ontologies including bibliographic ontology, lcc ontology, ddc ontology, udc ontology, and dmoz ontology. some of these ontologies were designed specifically for certain targeted applications e.g., acm ontology for acm digital library, and lcc ontology for library of congress etc., whereas others have multiple usage scenarios and have been used by several applications. an example of such general-purpose information technology and libraries | september 2017 64 bibliographic classification ontology is the bibliographic ontology17, which is used by several bibliographic services and digital libraries e.g., digital object identifier (doi), zotero, and library of congress classification number (lccn) permalink service (giasson, 2012). this evaluation framework compares these ontologies based on their size (in terms of number of classes), usage in the state-of-the-art applications, lod support, the availability of datasets on datahub18, and lov support. by looking at table 3, acm show more comprehensiveness

doi:10.6017/ital.v36i3.8930 65 issues & challenges in classification research although bibliographic classification has been practiced since the use of books and the inception of library & information science practices, further research & development efforts are required for to meet the classification needs of the digital age. especially, with the arrival of digital holdings, researchers face several issues and challenges. for example, automatic text classification performs categorization of resources using ordinary metrics including tf-idf and classification in its true sense is yet to be achieved (yi, 2006). to handle the issue, text classification is also carried out through semantic indexing but its accuracy and precision are yet to be achieved. semantic and structural relationships among different parts of text corpus is still at infant level and has not been exploited to their fullest so that these can be used in text classification in more meaningful ways. other challenges in text classification include handling huge data resulted by applying a classification scheme, dynamism in classification, and structure dissimilarity among classification schemes although they agree upon subject as the primary characteristic. the biasness in ddc and lcc needs to be resolved. several revisions and proposals are put forward for addressing the problem of systematic knowledge organization and searching through natural language terms (miksa, 2007). there are various issues regarding the structural updates, search & retrieval criteria, and visualization (slavic-overfield, 2005). there are two main challenges for the application of the bibliographic classification principles in classifying the web. first, the principles of the bibliographic classification are formulated for the printed documents, which should also be applicable to digital collections. for addressing these challenges, there is need to apply and modify bibliographic classification principles in digital environments. second, it is required to exploit hidden hierarchies and concepts to be better classified by the principles of bibliographic classification for precise discovery, search and retrieval (j. mai, 2004). the issue of dependent process of classification of any object per predefined criteria and principles is important to address for finding a place in this age of search engines. this issue can be tailored by the principles of classification, so that the conventional principles are modified to consider the purpose of classification and domain of objects. for this issue semantic web and ontologies can play a vital role in bibliographic classification, which can provide independent classification of the bibliographic classification predefined theories (hjørland, 2012). the issue of heterogeneity conflicts, which arise because of the inconsistencies and structural divergences, are the challenges for the semantic interoperability. semantic interoperability can be brought into the bibliographic records inside the bibliographic system and across the systems through different phases of interlinking, evaluation, analysis, remodeling & conversion for analyzing, and restructuring the bibliographic data (tallerås, 2013). bibliographic data is in multi-format, multi-topical, multi-lingual and multi-targeted. for tackling these issues, the bibliographic data must be made mutually interoperable for making it information technology and libraries | september 2017 66 interlinked, searchable, and presented in a harmonized way across the boundaries of the datasets and data silos. the interoperability problem arises at the syntactic level for making consistent the character sets, notations, data formats and records in different systems. the interoperability problem is also arising at the semantic level because of the difference in data interpretations and difference in vocabularies, and precision levels in data encoding. publishing, collecting and maintenance of bibliographic data by multi organizations through own established standards and best practices in web 2.0 (hyvönen, 2012). with these problems in hand, the transition of this data from syntactical web to semantic web is a challenge for bringing the uniformity in records that are generated by diverse sources, encoded in multi-bibliographic systems, cross bibliographic systems interoperability, the visualization of bibliographic data accordingly as per need for different contexts. for addressing these problems there is a need for coordination and collaboration between bibliographic data publishers and the technical developers of the web applications (hyvönen, 2012). there is variety of metadata standards and schemas for defining, managing, resource discovery, search & retrieval, preserving, mapping, cross-walking, integrity, accuracy, and authenticity of metadata and bibliographic data. but for these tasks to be handled with great simplicity, semantic richness and accuracy, a universal all in one metadata format and schema is the need of the day (ramesh, vivekavardhan, & bharathi, 2015) to get out of this jungle of standards (gartner, 2016). this way, the metadata publishers and managers could get relieved and the job will become economic in terms of time, management, and search & retrieval. three main tasks were set in semantic publishing challenges 2015. these tasks are: (i) extracting data on workshops’ quality indicators; (ii) extracting data on affiliations, citations, funding; and (iii) interlinking. several challenges were faced while fulfilling these tasks. these tasks are being fulfilled through a proposed solution, which is composed of a text mining pipeline, lodexporter and named entity recognition (ner) for named entities extraction form text and linking them to resources on the lod cloud (sateli & witte, 2015). in (peroni, 2012) three main issues of semantic publishing are addressed which are: lack of document publishing universal metadata schemas according to publishing vocabulary, lacking of efficient user interface that are based on models and theories of semantic publishing, and there is a need for a tool that semantically link and describe document text. these issues require the urgent need for comprehensive ontologies for document publishing domain. (ferrara & salini, 2012) tossed 10 challenges for multiple dimensions of data in terms of bibliographic analysis. these challenges are: (i) analyzing bibliographic data in a multidimensional pattern; (ii) discovering and integrating data coming from diverse sources; (iii) detecting multiple references to the same item and cleaning, normalizing, and disambiguating bibliographic data records; (iv) analyzing multidimensional nature of bibliographic data through multivariate analysis for aggregating the data; (v) comparing different elements of bibliographic data and its ranking accordingly, (vi) aggregating indexes of different nature with respect to bibliographic classification in the digital age | ullah, khusro, and ullah | doi:10.6017/ital.v36i3.8930 67 different parameters, dimensions, and elements of bibliographic data; (vii) dealing with multiple indexes for the same item with different values coming from different sources; (viii) extracting and indexing textual information from text corpus in support of text mining; (ix) analyzing textual data topic-wise and describing these topics for research and learning process and tracing different trends; and (x) combining multidimensional information for finding trends in bibliographic data collection. bibliographic classification systems are being incorporated in lod. in dewey.info27, a prototype version of ddc is designed for linking its dataset in linked data cloud. the intention is to provide a platform for ddc data on the web having summaries of top 3 levels of classification order of ddc 22nd edition in 11 different language encoded in rdf/skos, having actionable uris for every class, representation for machines is in rdf, and for humans in xhtml+rdfs, and serialization available in formats of rdf/xml, turtle and json, and with sparql endpoint. (oclc 2011; mitchell and panzer 2013). however, this version of ddc on lod cloud is still at infant stage to cover different subjects and to be widely used in generating and creating documents metadata. library of congress linked data service provides access to commonly used standards and vocabularies developed by library of congress. this includes data values, controlled vocabularies, and preservation vocabularies which are part of this service. this service provides access to lcsh, lcc name authority files, lcc28, lc children's subject headings, lc genre/form terms, thesaurus for graphic materials, marc relators, marc countries, marc geographic areas, marc languages, iso639-1 languages, iso639-2 languages, iso639-5 languages, extended date/time format, preservation events, and preservation level role and cryptographic hash functions. the authorities and vocabularies currently included in this service are listed on the linked data service (library of congress 2014). however, it lacks in vocabularies for supporting premis, marc, mods, mets, and mix. as presented in section 2, several ontologies have been developed for describing and sharing knowledge about bibliographic classification. however, the available ontologies are limited in several ways e.g., these ontologies are not the complete clones of classification schemes of which they are deemed to be ontologies and they also not mature enough in terms of metadata collection. in addition, these ontologies still couldn’t break the cross-classification scheme metadata collection barriers i.e., they are not interoperable enough to harvest the metadata across bibliographic ontology system. therefore, further initiatives are required to develop matured bibliographic ontologies which fully clone bibliographic schemes that are in practical use and have strong theoretical ground. these ontologies must be interoperable and sharing metadata collection with other bibliographic ontologies. in this way in future we can have ontology-based general bibliographic classification system by fusion of the new and existing bibliographic ontologies for better management of the knowledge artifacts. 27 https://datahub.io/dataset/dewey_decimal_classification information technology and libraries | september 2017 68 conclusions with the arrival of digital collections, new challenges of preservation, curation as well as resource discovery & access (retrieval) have emerged that needs proper attention, where classification schemes and ontologies can play a significant role. by comparing and evaluating the available bibliographic classification and categorization systems it is concluded that currently ddc is the best classification system followed by udc, and acm. the bibliographic classification ontologies are limited in one way or the other e.g., some of these are comprehensive like udc and acm but lack support for lod and lov etc., while others support these later aspects but lack comprehensiveness. keeping in view the available bibliographic classification ontologies and their limitations, we recommend that a universal bibliographic classification ontology should be developed by using the classes from the available ontologies and providing support in terms of availability of datasets, support for interoperability, lod, and linked data vocabularies. for developing a more meaningful classification system, equally applicable to digital environments, it is necessary to consider the book structural semantics such as table of contents, headings, chapters, sections, subsections, figures, algorithms, mathematical equations, quotations etc., and the logical connections in contents (khusro & ullah, 2016; i. ullah & khusro, 2016) as well as about the book information i.e., the bibliographic details of the holdings. to meet, the former requirement, a comprehensive ontology like bookont (a. ullah, ullah, khusro, & ali, 2016) could be used, which can be mapped with any bibliographic ontology like e.g., bibliographic ontology29. however, as the evaluation frameworks suggest, ddc, udc, and acm classification system should be exploited in designing such a general-purpose classification system. references the 2012 acm computing classification system. retrieved march 20, 2017, from http://www.acm.org/about/class/2012 about universal decimal classification (udc). retrieved march 21, 2017, from http://www.udcc.org/index.php/site/page?view=about albrechtsen, h.

planning this column, i looked back over my other columns for the year and discovered that they have a theme: the connection that runs from our past, through our present, and into our future. in my first column, i talked about the first issues of ital: henriette avram founding marc right here in these pages. early lita hackers cobbling together the technologies of their age to make streamlined, inventive library services — just as lita members do today. in my second column, i talked about conferences where we come together today — lita forum 2017 and 2018 — and encounter the issues of today — data for black lives. i can close my eyes and i’m in denver, chatting with long-time colleagues and first-time presenters ... or i’m at the mit media lab, watching algorithmic opportunity and injustice spar with one another, while artists and poets point us toward the wakandan imaginary. and in my third column, i talked about the possibility of lita, llama, and alcts coming together to form a new division: a potential future. this possibility both knocked my world off its axis and let me see it in a new light; i didn’t imagine that i’d spend my presidency exploring the options for large-scale organizational transformation, and yet i can see how this route could not only address challenges all three divisions face, but also give us opportunities to be stronger together. i believe in this roadmap, but i also want us all to grapple with the question of identity. what’s peripheral, and what’s central, to who we are as library technologists? what’s ephemeral, and what endures? what’s the through line we can hold on to, across that past and present, and carry with us into the future? today, here in the present, i’m preparing to turn over my piece of that line to president-elect bohyun kim. she has been unfailingly brilliant and diligent in the years i’ve known her, and i know she’ll ask insightful questions, advocate for all that’s best in lita and its people, and get things done. but i’m also cognizant that it was never really my line; it was yours. i had the immense privilege of carrying it for a while, but as we hear every time we survey our members, the best part of lita is the networking — it’s you. we will have many chances to discuss our through line in the months to come and i urge you to bring your voices to the table: ask your questions, tell us what matters, and depict your imaginaries. mailto:andromeda.yelton@gmail.com a collaborative approach to newspaper preservation public libraries leading the way a collaborative approach to newspaper preservation ana krahmer and laura douglas information technology and libraries | september 2020 https://doi.org/10.6017/ital.v39i3.12596 ana krahmer (ana.krahmer@unt.edu) oversees the digital newspaper unit at unt. through this work, she manages the texas digital newspaper program collection on the portal to texas history, which is a gateway to historic research materials freely available worldwide. laura douglas (laura.douglas@cityofdenton.com) is the librarian in charge of the special collections with the denton public library which houses the genealogy, texana, and local denton history collections as well as the denton municipal archives. in her work, she regularly assists patrons with newspaper research questions specifically related to denton newspapers. © 2020. introduction when we first proposed this column in january 2020, we had no idea how much the world would change between then and the july deadline. while we have collaborated for many years on a variety of projects, the value of our collaboration has never proven itself more than in this covid 19 reality: collaboration leverages the strengths and resources of partners to form something stronger than each. in this world of covid-19, the collaboration between the denton public library (dpl) and the university of north texas libraries (unt) has allowed us to build open, online access to the first 16 years of the denton record-chronicle (drc). this newspaper is the city’s daily newspaper of record, and the collaboration between dpl and unt resulted in free, worldwide research access, via the portal to texas history. the project was funded by a $24,820.00 grant through the imls library services and technology act (lsta), awarded from september 2019 to august 2020 by the texas state libraries and archives commission (tslac) as part of their textreasures program, to digitize 24,000 newspaper pages. this project has also resulted in a follow-up collaboration to build open access to further years of this daily newspaper title, through a 2021 textreasures award to digitize an additional 24,000 newspaper pages. the real question, though, is what recipe made this a successful collaboration. background the drc has been the community newspaper in denton for over 100 years. due to the sheer amount of material, digitizing a daily newspaper with such an extensive publication run is a long term project that requires a lot of planning, time, and funding. since the dpl’s inception in 1937, the library has endeavored to collect items related to denton and texas history. with community support, the library has developed a well-rounded collection of local history, texana, and genealogical materials, all of which are housed in the special collections research area at the emily fowler central library. these materials support research, projects, and exhibits. one major research resource is the archival collection of local newspapers, mainly the drc, maintained on 752 rolls of microfilm containing issues from 1908 to 2018. before this project, access to these newspapers was only available in the special collections research area, through microfilm readers or paid subscription services. in addition, although steps had been taken to preserve the film, many of the rolls show wear from years of use, while others have developed vinegar syndrome and soon will no longer be a usable resource. in 2018, unt obtained publisher permission to make the drc run freely accessible on the portal to texas history. mailto:ana.krahmer@unt.edu mailto:laura.douglas@cityofdenton.com information technology and libraries september 2020 a collaborative approach to newspaper preservation | krahmer and douglas 2 laura had been exploring different avenues to digitize this microfilm and make them freely available to the public when ana contacted her with information about the texas state library and archives commission (tslac), which awards annual grants supported by library services & technology act funds, through the institute of museum & library services. lsta funding is annually provided to all fifty states through the institute of museum and library services, and the state library determines how this funding is expended. in texas, lsta funding is provided through a number of grant programs including textreasures, a competitive grant program for any texas library. as described by tslac, the “textreasures grant is designed to help libraries make their special collections more accessible for the people of texas and beyond. activities considered for possible funding include digitization, microfilming, and cataloging.” libraries can apply to fund the same type of project up to three years in a row, and the drc project applied for $24,820.00 in 2019 to digitize 24,000 newspaper pages, representing the earliest years of microfilm available at the denton public library. to create a viable grant application dpl partnered with the texas digital newspaper program (tdnp), available through unt’s portal to texas history, and decided to start first by digitizing as many early years of microfilm as grant funding could cover. tdnp is the largest single-state, open access, digital newspaper preservation repository in the u.s., hosting just under 8 million newspaper pages at the time of this writing. in late 2018, unt received permission from the owner of the drc to include the newspaper run in the tdnp collection, which represented a very exciting opportunity for city and county researchers, as well as for the dpl. as thanks to the publisher for granting permission, unt built access to the 2014 to 2018 pdf eprint editions, which the tdnp preserves as a service to texas press associationmember publishers. after this, unt contacted the dpl to discuss applying for grant funding. once laura learned that the dpl had received the 2019 award, she prepared the local planning steps necessary to collaborate with the university. the project becomes real the denton record-chronicle digitization project grant contract and resolution for adoption went before the denton city council on october 8, 2019. the city of denton issued a press release that day, and the drc also published an article announcing the project. over the next few days the drc article appeared across social media, including the city of denton’s social media accounts, as well as through library-associated email newsletters. after the first newspapers became available on the portal, both dpl and unt prepared blog posts about the project, which have also appeared on social media. these blog posts fulfilled publicity requirements specified by the grant, even while offering training to researchers in how to work with the online newspaper collection. one major convenience to this collaboration is that both organizations are in the same city. transfer of materials was arranged by email and accomplished by a trip across town. we completed the digitization process in batches, with the first 10 microfilm rolls going to unt on october 10, 2019, and unt uploading the first 854 issues in december 2019. the newspapers from the first microfilm set represented 1908-1916. dpl transferred the last set of microfilm in april 2020, with dates ranging from 1917 through september 1924, shortly after which unt completed and uploaded the grant-funded count of 24,000 newspaper pages. the estimated year given in the grant proposal that the scans would have gone through was 1938, but the page count on this newspaper proved to be much, much higher than originally estimated, and as a result, the funding only covered up to september 1924. dpl and unt will continue their partnership by information technology and libraries september 2020 a collaborative approach to newspaper preservation | krahmer and douglas 3 digitizing further years of the drc, through a variety of methods. as we were in the midst of preparing this column the tslac contacted laura to inform her that dpl had received a second grant award, in the amount of $24,820.00 to digitize 24,000 additional newspaper pages, which will move the newspapers through 1954. as of july 23, 2020, the denton record-chronicle collection on the portal to texas history hosts 6,168 items and has been used 16,397 times. this includes 1,743 items that are pdf eprint editions of the paper from 2014 to 2018, which unt uploaded for long-term preservation and access. unt uploads eprint editions without a charge, and digitally preserves these through an agreement with the texas press association; these pdfs were not a part of the funded grant, but they do enhance access to the collection and helped to build community interest in seeing earlier years available on the portal. the usage of the collection skyrocketed after the early editions became available. january 2020 saw the highest number with the collection uses at 3105. once this project is complete, it will include over 200,000 newspaper pages. neither dpl nor unt has the ability to tackle this project on their own, but through collaboration, it is possible. recipe for your own collaboration success these are planning recommendations as you prepare for your own collaboration, drawn from what we’ve learned as we worked on this project together. 1. communicate early and often: communicating needs enables partners to identify each other’s strengths. each partner will bring their strengths to the project, which in this case included actual archival materials from dpl and technological expertise on the unt side. in addition, be prepared to communicate with local groups who need to endorse or sign off on the project, including possibly the city council, the historical commission, or the city manager. 2. partner to write the grant: partnering in preparing the grant achieves two goals: first, it enables partners to develop a communication flow that will move forward throughout the collaboration; second, it ensures that partners know what each can realistically accomplish within the grant timeline. in this case, laura wrote most of the grant application herself, but she had very specific questions that ana had to answer, and she needed key elements from unt, including project budget, technological infrastructure, and a commitment letter. communicating early and partner on the grant application process ensured that there were no unexpected surprises that were within the control of either partner. 3. work together to explain your partnership: with a grant of this size, we always spoke in advance to ensure we weren’t over-promising when newspapers would appear online. this also gave both laura and ana lead-time for promoting the project: laura would share the years of the physical microfilm before sending them over, and ana would walk laura through the years that would get uploaded in a given month. this allowed them to plan publicity, training, and outreach efforts based on the dates of newspapers going online. in addition, laura regularly communicated with ana prior to submitting grant reports, and this was critical in preventing miscommunication going to the funding agency. 4. pad enough time for the unexpected: of course, we had no way of knowing a pandemic would occur when we began this project, and what saved us was that we’d started planning as soon as we learned about receiving the grant, rather than as soon as the grant started, which was in september 2019. planning two months in advance put us two months ahead of schedule, and we were able to start exchanging materials as soon as the grant period information technology and libraries september 2020 a collaborative approach to newspaper preservation | krahmer and douglas 4 started. this gave us a few weeks of lead time so we successfully completed the project by the end of april 2020, at which point the microfilm page count had been scanned and unt staff could remote in to complete the digitization processes. extra time is only a benefit. if the covid-19 pandemic had not occurred, we still might have had to address technological or film deterioration problems, and we could resolve these earlier rather than later because we had given ourselves a few extra weeks of lead time. 5. don’t be afraid to explain changes to your granting agency: if your project changes due to unforeseen circumstances, for example in our project the uploaded total of pages reached 24,000 before we digitized the entire planned date range. unt charges a per-page digitization fee, and these newspaper issues proved to contain more pages than expected . laura contacted the representative at tslac to explain the situation and offer an alternative approach to cover the digitization of the remaining years. the important thing is to keep the granting agency informed of any changes, delays, or hiccups in the project. we are both proud of having completed this project three months before the end of the grant period, but we know that without solid communication, planning, or flexibility, the covid-19 pandemic would have made the situation extremely difficult if not impossible. leveraging the portal’s technical infrastructure and tdnp’s newspaper expertise with the volume of material and collection expertise provided by the dpl has given us a model for success we plan to capitalize on in future projects. best of all, in the world of covid-19, our patrons can access these newspapers from the comfort of their own couches, without even taking off their pajamas! introduction background the project becomes real recipe for your own collaboration success editorial | truitt 87 l ife out of balance. those who saw it will surely recall the 1982 film that juxtaposed images of stunning natural beauty with scenes of humankind’s intrusion into the environment, all set to a score by philip glass. the title is a hopi word meaning “life out of balance,” “crazy life,” “life in turmoil,” “life disintegrating,” or “a state of life that calls for another way of living.” while the film, as i recall, relied mainly on images of urban landscapes, mines, power lines, etc., to make its point about our impact on the world around us, it did include as well images that had a technological focus, even if the pre–pc technology exemplars shown may seem somewhat quaint thirty years later.1 the sense that one is living in unbalanced, crazy, or tumultuous times is nothing new. indeed, i think it’s fair to say that most of us—our eyes and perspectives firmly and narrowly riveted to the here and now—tend to believe that our own specific time is one of uniquely rapid and disorienting change. but just as there have been, and will be, periods of rapid technological change, social upheaval, etc.—“been there, done that, got the t-shirt,” to recall the memorably pithy, if now slightly oh-so-aughts, slogan—so too have there been reactions to the conditions that characterized those times. a couple of very different but still pertinent examples come to mind. in the second half of the nineteenth century, a reaction against the social conservatism and shoddy, mass-produced goods of the victorian era began in england. inspired by writer and designer william morris, the arts and crafts movement emphasized simplicity, hand-made (as opposed to factory-made) objects, and social reform. by the turn of the century, the movement had migrated to the united states—memo to self: who were the leading lights of the movement in canada?—finding expression in the “mission-style” furniture of gustav stickley, the elegant art pottery of rookwood, marblehead, and teco, and the social activism of elbert hubbard’s roycrofters. fast-forward another half-century to the mid-1960s and the counter-culture of that time, itself a reaction to the racism, sexism, militarism, and social regimentation of the preceding decade. for a brief period, experimentation with “alternative lifestyles,” resistance to the vietnam war, and agitation for social, racial, and sexual change flourished. whatever one’s views about, say, the flower children, civil rights demonstrations, or the wisdom of u.s. involvement in vietnam, it’s well-nigh impossible to argue that the society that emerged from that time was not fundamentally different from the one that preceded it. that both of these “movements” ultimately were subsumed into the larger whole from which they sprang is only partly the issue. and my aim is not to romanticize either of these times, even as i confess to more than a passing interest in and sympathy for both. rather, my point is that their roots lay in a reaction to excesses—social, cultural, economic, political, even technological—that marked their times. they were the result of what might be termed “life out of balance.” in turn, their result, viewed through a longer lens, was a new balance, incorporating elements of the status quo ante and critical pieces from the movements themselves. thesis —> antithesis —> synthesis. we find ourselves in such unbalanced times again today. even without resort to over-hyped adjectives such as “transformational,” it is fair to say that we are in uncertain times. in libraries, budgets, staffing levels, and gate counts are in decline. the formats and means of information delivery are rapidly changing. debates rage over whether we are merely in the business of delivering “information” or of preserving, describing, and imparting learning and knowledge. perhaps worst of all, as our role in the society of which we are a part changes into something we cannot yet clearly see, we fear “irrelevance.” what will happen when everyone around us comes to believe that “everything [at least, everything that’s important] is on the web” and that libraries and librarians no longer have a raison d’être? for much of the past decade and a half—some among us might argue even longer—we’ve reacted by taking the rat-in-the-wheel approach. to remain “relevant,” we’ve adopted practically every new fad or technology that came along, endlessly spinning the wheel faster and faster, adopting the tokens of society around us in the hope that by so doing we would stanch the bleeding of money, staff, patrons, and our own morale. as i’ve observed in this space previously,2 we’ve added banks of über-connected computers, clearing away book stacks to design technology-focused creative services and collaborative spaces around them. we’ve treated books almost as smut, to be hidden away in “plain-brown-wrapper” compact storage facilities. we’ve reduced staffing, in the process outsourcing some services and automating others so that they become depersonalized, the library equivalent of a bank automated teller machine. we’ve forsaken collection building, preferring instead to rent access to resources we don’t own and to cede digitization control of those resources that we ostensibly do own. where does it end? in a former job, i used to joke that my director’s vision of the library would not be fully realized until no one but the director and the library’s system administrator were left on staff and nothing but a giant super-server remained of the library. it seemed only black humor then. today it’s just black. marc truitt

ital. editorial: koyaanisqatsi 88 information technology and libraries | september 2011 and intellectual rest. they are places of the imagination. play to these strengths. those seeking to reimagine library spaces as refuges could hardly do better than to look to jasper fforde’s magical bookworld in the thursday next series for inspiration.3 stuffy academics and special libraries take note: library magic is not something restricted to children’s rooms in public libraries. walk through the glorious spaces of yale’s sterling memorial library or visit the reading room at the university of alberta’s rutherford library—known to the present generation of students as the “harry potter room,” for its evocation of the hogwarts school’s great hall—and then tell me that magic does not abound in such places. it’s present in all of our libraries, if we but have eyes to see and hearts to feel. ■■ the library was once a place for the individual. to contemplate. to do research. to know the peace and serenity of being alone. in recent years, as we’ve moved toward service models that emphasize collaboration and groups, i think we’ve lost track of those who do not visit us to socialize or work in groups. we need to reclaim them by devoting as much attention to services and spaces aimed at those seeking aloneness as we do at those seeking togetherness. the preceding list will probably brand me in the minds of some readers as anti-technology. i am not. after spending the greater part of my career working in library it, i still can be amazed at what is possible. “golly? we can do that?” but i firmly believe that library technology is not an end in itself. it is a tool, a service, whose purpose is to facilitate the delivery of knowledge, learning, and information that our collections and staff embody. nothing more. that world view may make me seem old fashioned; if such be the case, count me proudly guilty. in the end, though, i come back to the question of balance. there was a certain balance in and about libraries that prevailed before the most recent waves of technological change began washing over libraries a couple of decades ago. those waves disrupted but did not destroy the old balance. instead, they’ve left us out of balance, in a state of koyaanisqatsi. it’s time to find a new equilibrium, one that respects and celebrates the strengths of our traditional services and collections while incorporating the best that new technologies have to offer. it’s time to synthesize the two into something better than either. it’s time for balance.

living in a state of koyaanisqatsi (life out of balance). and it’s up to us to do something new about it by creating a new balance. here are a few perhaps out-of-the-box ideas that i think could help with establishing that balance. spoiler alert: some of these may seem just a bit retro. i can’t help it: my formative library years predate the chicxulub asteroid impact. anyway, here goes: ■■ cease worrying so about “relevance.” instead, identify our niche: design services and collections that are “right” and uniquely ours, rather than pale reflections of fads that others can do better and that will eventually pass. we are not google. we are not starbucks. we know that we cannot hope to beat these sorts of outfits at their games; perhaps less obvious is that we should be extremely wary of even partnering with them. their agenda is not ours, and in any conflict between agendas, theirs is likely to prevail. we must identify something unique at which we excel. ■■ find comfort in our own skins. too many of us, i sense, are at some level uneasy with calling ourselves “librarians.” perhaps this is so because so many of us came to the profession by this or that circuitous route, that is, that we intended to be something else and wound up as librarians. get over it and wear the sensible shoes proudly. ■■ stop trying to run away from or hide books. they are, after all, perceived as our brand. is that such a bad thing? ■■ quit designing core services and tools that are based on the assumption that our patrons are all lazy imbeciles who will otherwise flee to google. the evidence suggests that those folks so inclined are already doing it anyway; why not instead aim at the segment that cares about provision of quality content and services—in collections, face-to-face instruction, and metadata? people can detect our arrogance and condescension on this point and will respond accordingly, either by being insulted and alienated or by acting as we depict them. ■■ begin thinking about how to design and deliver services that are less reliant on technology. technology has become, to borrow from marx, the opiate of libraries and librarians; we rely on it to the exclusion of nontechnological approaches, even when the latter are available to us. technology has become an end in itself, rather than a means to an end. ■■ libraries are perceived by many as safe harbors and refuges from any number of storms. they are places of rest—not only of physical rest, but of emotional editorial | truitt 89 editorial.cfm (accessed july 13, 2011). 3. begin with fforde’s

nsdp, and isbd-s josephine s. pulsifer: marc development office, library of congress, washington, d.c. 193 editor's note: the discrepancies and variations described in this docurmnt are being examined by an ad hoc serials discussion group, and are being resolved by the staffs of the library of congress and the national serials data program. readers are referred to the discussions of richard anable and audrey grosch, in this issue. briefly characterizes and compares the specifications for serial records of the marc serials distribution service, the national serials data program, and the international standard bibliographic description for serials. both data content and, where applicable, machine format are analyzed. introduction that current interest in machine-readable serial records is running high is evidenced by the recent establishment of the ad hoc serials discussion group, the questionnaire from the arl ad hoc committee on machinebased serial records, and various union lists of serials projects. there is recognition of the inability of libraries to support unilateral conversion of serial records to machine-readable form and of the undesirability of creating uncoordinated data bases which are compatible neither in bibliographic data nor machine format. new developments three recent developments, while all directed towards standardization, are nevertheless adding to the confusion of those libraries which, singly or in groups, are attempting to determine how best to acquire the required serials data base. these three developments are: ( 1) the marc serials distribution service ( marc-s); ( 2) the international standard bibliographic description for serials (isbd-s); and (3) the national serials data program ( nsdp). each of these efforts has a somewhat different goal, operates within different constraints, and is to some degree in conflict with the other two. 194 journal of library automation vol. 6/ 4 december 1973 marc serials distribution service the marc distribution service distributes machine-readable records for all library of congress ( lc) serials in roman alphabet languages given printed card cataloging since february 1, 1973. romanized records for serials in nonroman alphabets will be added in the fall of 1973. records for recataloged serials are also included. the goal of marc-s is the creation of multipurpose machine-readable serial records, with standard catalog data in the marc serials format, for lc's own data base and for dissemination to libraries and related communities.1 these records follow the anglo-american cataloging rules (aacr), with superimposition of entries established under earlier rules.2 consideration is being given to· abandonment of superimposition. approximately 3,000 serial titles in lc's main reading room and science reading room collections have been converted to marc and will be made available for distribution as soon as possible. e~'pansion of the service to a phased conversion of records for retrospective but active titles would be most desirable, beginning with some identifiable and widely useful subset. expansion would require both space and funds and a determination of priorities between automation of new serial titles and progress towards a comprehensive data base for lc current serial receipts. national serials data program the nsdp is the united states national center of unisist' s international serials data system ( isds), which has sole responsibility for controlling the assignment of the international standard serial number ( issn). to nsdp is delegated responsibility for the assignment of the issn to serials published in the united states. serials published outside the u.s. are assigned by the appropriate national center or by the international center in paris. besides its isds responsibility, nsdp has as a prime objective the provision of a data base of serial publications for the three national libraries (library of congress, national agricultural library, and national library of medicine) . the program is aimed to be of benefit to the national user community, including libraries, subscription agencies, publishers, and abstracting and indexing services. as set forth in the isds guidelines, isds centers will develop and maintain national registers of serial publications, containing all the necessary information for the identification of the serials. the international center is to distribute a printed register (in issn and title sequences) as well as a machine file of all titles, including a regular supplement. nsdp plans to publish similar registers containing a subset of the international register. 0 0 the information on isds and nsdp has been taken from the following publications: (1) isds guidelines--nsdp copy. (received april 16, 1973.) (2) national serial data program, "notes on special development in the program," no. 2 , january 1973 [p. 1}. comparison of marc serialsjpulsifer 195 nsdp must follow the isds guidelines in providing to the international center a set of data elements considered essential for identification of the serial. certain other elements are defined as optional isds elements. nsdp has defined certain additional elements as needed for the national record. international standards organization (iso) standards must be followed where applicable. international standard bibliographic description for serials the isbd-s defines the elements necessary for the identification of serials, assigns an order to these elements in the entry1 and specifies the punctuation designating these elements. 3 the isbd-s, as a descriptive catalog record only, is not concerned with access points to the record (i.e., entries) . it is not a machine format, though its standard order of elements and standard punctuation greatly assist the machine identification (i.e., format recognition) of the various elements. the work of the working group on the international bibliographic description for serials of the international federation of library associations has been completed and will soon be published. this document will be subject to revision following a period of study and/ or use by ifla member organizations. the isbd-s will be put into practice by lc when it is accepted by the american library association and incorporated into the anglo-american cataloging rules. comparison of data content: marc-s, nsdp, and isbd-s entry marc-s: lc practice in choice of entry (author/title vs. title) based on aacr 6a--6c, is followed. the form of entry is that used by the library of congress1 i.e., aacr with superimposition. when main entry is under author, the author is usually omitted from the title field. nsdp: the isds includes no name entry, main or added, in its essential or additional data elements. names are included in the key title under certain circumstances. however, nsdp has added "author entries" as an essential national data element, along with a means of indicating the aacr main entry. these author entries are established by nsdp following aacr form of entry without superimposition, and an authority file is maintained to relate variant forms of entry used by the national libraries to the nsdp form. isbd-s: isbd-s (like isbd-m) is not concerned with entry. it does not preclude main or added entries, but provides a description that does not depend on entry for identification. an author statement follows the title, unless the author is part of the distinctive title or there is no author. title and statement of authorship marc-s: the title is transcribed from the title page according to aacr. subtitles are omitted unless necessary for the identification of the publication. the author statement is omitted when the author appears in 196 journal of library automation vol. 6/4 december 1973 substantially the same form in the main entry or when there is no author. the marc format provides an additional field for "title as it appears on the piece," but this field is not included in marc-s records at the present time. nsdp: the key title is the title as it appears on the piece. it may include the issuing body when the name is grammatically, typographically, or visually linked to the rest of the title or when it is needed to make a generic title distinctive. in addition, it may be modified by place and/ or date of publication to make it unique. nsdp assigns a new issn and creates a new record when the wording of the key title changes. • • "minor" changes, including prepositions and spelling changes that may significantly change filing, do not result in a new record or issn. where the author or issuing body changes, no new record is created unless the author is part of the key title. because a new record means a new key title and new issn, the determination as to whether a ti· tie change is to result in a new record may only be made by the official isds agency. when the author statement is not grammatically linked to the title and the title is a "generic" term, the author statement is added to the title but separated from it by a dash. the interpretation of generic is limited, according to the isds guidelines, to terms denoting the kind and/ or periodicity of a publication.' a study of the differences in practice between lc and nsdp with respect to creating new records for change of title is attached. isbd-s: the isbd-s "distinctive" title is essentially the same as the nsdp key title with the important differences that it need not be unique, and that it is always followed by an author statement unless the author is part of the distinctive title or there is no author. therefore, there is no requirement for centralized determination of the distinctive title. this determination can be performed by any library or any other organization by applying the isbd-s rules. this paper does not attempt to point out all the differences among the three systems. it may be noted, however, that there are differences in the romanization schemes used by lc and nsdp, since nsdp uses iso romanization tables and lc uses ala romanization tables. 0 0 • nsdp also uses the country code being developed under iso while marc-s uses the country codes approved by the three national libraries. however, it is likely that when the iso code becomes a standard, it may be adopted for marc-s. references 1. library

scientific serial lists dana l. roth: central library, indian institute of technology, kanpur, u.p., india this article describes the need for user-oriented serial lists and the development of such a list in the california institute of technology library. the results of conversion from eam to edp equipment and subsequent utilization of com (computer-output-microfilm) is reported. introduction prior to the dedication of the millikan memorial library, which houses the divisional collections in chemistry, biology, mathematics, physics, engineering, and humanities, the libraries at the california institute of technology were largely autonomous, reflecting the immediate needs of each division, and exhibited little attempt at interdivisional coordination of library purchases. with centralization of the major science collections, it became apparent that any efforts to reduce duplication, promote more effective library usage, and provide assistance in interdisciplinary research efforts would require a published list of serials and journals ( 1). scientists vs librarians it is certainly a truism that serial publications constitute the backbone of a library's research collection. particularly in the sciences, where serial publications serve as the primary record of past accomplishments, studies have shown that over 80 percent of the references cited in basic source journals are to serials (see table 1). citation of serials rather than monographs was greater in chemistry than in other sciences and the overall order may reflect the efficiency of the respective abstracting/ indexing services. in spite of the scientist's heavy dependence on serials, it appears that in most libraries little attempt has been made to reconcile the library 52 ]oumal of library automation vol. 5/1 march, 1972 table 1. percentage of citations to serials found in basic source journals for various, scientific disciplines 0 discipline percentage of citations to serials ch em is

in the scientific literature. this is in part due to the general acceptance of the library of congress dictum that serials should be cataloged according to the general principles laid down for monographs. fortunately, monographs are generally cited in the scientific literature by entries (author / title ) which invariably appear in the library catalog. serials, however, present the special problems of so-called indistinctive titles, frequent title changes, and common reference to the abbreviated form of their title. most american libraries have followed the library of congress/union list practices and as a result have long suffered user complaints about the use of corporate entries for so-called indistinctive titles, entries under the latest form of title, and the treatment of prepositions and conjunctions as filing elements. these practices have been defended as attempts to extend the reference value of the catalog but in doing so they create a number of problems and ambiguities which are only partially resolved by the annoying use of see references. the recent surge of interest in making the library "relevant" and more intimately involved with its users needs must take into account that in the minds of scientists it is a presumptive requirement for them to remember cataloging rules when the library could just as well accommodate the scientific form. in recognition of the long-standing scientific tradition of describing serials by their titles (which considerably predates the corporate entry syndrome), the logical solution wou ld be to provide title added entries for those serials whose main entry is in corporate form ( 2). specific problems 1. even if scientists were to remember the basic rules for society publications and similar corporate entries, how are the exceptions shown in table 2 to be reconciled? 2. the practice of cataloging serials under their latest title then best serves as an obstruction to determining the library holdings, since referscientific serial lists/roth 53 table 2. an example of the difficulties encountered in translating abbreviations of scientific journal titles into lc entries abbreviation

and citations obtained from abstracting/ indexing services are obviously to the title currently in use. another important factor, that is sometimes overlooked, is the requirement of a classified shelf arrangement. otherwise, since the title of the bound volume corresponds to the title in use at the time of binding, you have the ambiguity of catalog referring to the latest title and shelf locator referring back to the earlier title. these problems are further complicated by the long d elays and backlogs in recataloging. in many large libraries this is a major function of serials catalogers and it is estimated that it takes 50 percent longer to recatalog than to catalog originally ( 3). 3. the jargon of scientists when discussing or requesting information about various periodicals is replete with acronyms and abbreviated forms. jags, pnas, berichte, comptes rendus, annalen all have well-defined meanings in scientific literature and conversation because of the well-developed title entries and abbreviations given in physics abstracts, chemical abstracts, and the world list of scientific periodicals. the use of prepositions and conjunctions as filing elements constrains these scientists to being able to translate these abbreviations only into title entries where the omitted words are obvious, e.g., journal of the american chemical society but often causes problems with titles like journal of the lesscommon metals. the cal tech serials list: objectives and procedures the publication of a serials list oriented to the needs of scientists must then provide for: scientific title entries for corporate and society publica54 journal of library automation vol. 5/1 march, 1972 tions, treatment of each title change as the cessation of the old title, and omitting prepositions and conjunctions as filing elements. these practices will increase the number of entries by about 40 percent over the number of current titles but in terms of user appreciation the extra expense is amply justified. the list can then be a logical extension of the library's reference service and offers the opportunity of facilitating the research efforts of its users by obviating the need to remember cataloging rules or visit the library to determine its holdings. input to the serials list was derived from the library's serials card catalog. the information was typed on oversize card stock and included the full main entry, holdings, and divisional library location, with additional data cards, as required, to reflect title changes. with this data base, an extensive search of the world list of scientific periodicals and list of periodicals abstracted by chemical abstracts was made to determine the additional scientific title entries to be incorporated in the list. (each departmental library provides a shelf locator which relates the various forms of entry in the serials list to that chosen for the bindery title and subsequent shelf location.) prepositions and conjunctions were replaced with ellipses in the final typing of multilith stencils required for the manual publication of the first edition of the cal tech serials list ( 4). during the spring of 1969, the decision was made to employ edp techniques in the publication of the second edition of the list. as an interim housekeeping device between editions, the author maintained an in-house supplement on punch cards using a single card format. this experience indicated an unacceptable severity of title abbreviation which was obviated by adopting a two-card format. this is consistent with the ibm 360 system wherein input records are read two cards at a time, and thus, the unit record may be thought of as a "super" card of 160 columns (of which only a maximum of 131 columns can be printed on a given line, the remaining 29 columns being used for internal records). the unit serials record consists of the title, holdings, divisional library, serial number, and spacing command (see table 3). the unit records were created directly from the existing serial list and the cumulated supplement by in-house clericals. this obviated the usual requirement of coding the data for keypunch operators. subsequent to the preparation of the unit records, having an alphabetical sequence of punched cards, it was a simple matter to program the computer to serially number each second card, using orre letter and six digits. an example of the distribution of titles one might expect is given in table 4. while the data conversion was being performed, a series of programs was written. these programs were designed to create a master tape, update the tape, and to produce a variety of listings. these listings, in addition to the required 131-column printout for the serial list, include the 160-column table 3. the unit serials record card no. columns 1 1-75 2 1-27 2 29-32 2 72-78 2 80 scientific serial lists/roth 55 field designation title holdings divisional library serial no. spacing

printouts for individual divisional libraries which can be annotated with shelf locations. the data base was then transferred from punch cards to magnetic tape and subsequent additions and changes involve punch cards and tape one onto tape two operations. as a protective device tape one and tape two are the current and previously current tapes, respectively. thus in the case of accident the preceding tape can again be updated. as a further precaution the original punch card data base and update decks are on file. the economic justification for the use of edp equipment in libraries is based upon the necessity of maintaining current records that can be published at regular intervals. in the special case of serial lists this involves the periodic merging of small numbers of new and corrected unit records with the much larger number of unit records in the existing data base. the use of serially numbered unit records allows the relatively easy machine function of merging numbered items in contrast with the difficulties involved in merging large alphabetical fields. recent advances in reprographic technology suggested that com (computer-output-microfilm) could be utilized to produce a quality catalog, free of the normal objections to "computer printout." the flexibility of currently available com units allows the acceptance, as input of a normal print tape from most computer systems (ibm, burroughs, univac) 56 journal of library automation vol. 5/1 march, 1972 table 5. data presentation and relative spacing title holdings divisional library faraday society,

processors resident in the front-end computer of the fr-80, for example, allow for upperand lowercase, gold characters, column format, pagination, and sixty-four-character sizes. variation in character size allows a maximum density of 170 characters per line and 120 lines per ( 8~ x 11 ) page. the application of com equipment requires the production of a "print tape." this is simply a coded version of the current tape which contains the additional instructions necessary for spacing the unit records, defining the page size, and inserting "continued on next page" statements. the use of spacing command instruction, as an integral part of the unit record, allows all the information on a given title to remain in one unit and easily provides for a blank line before the next title ( see table 5). the additional problem of keeping the information on one title together on a given page or providing a "continued on next page" statement was solved by analyzing the information in the eighty-ninth line of each page to determine whether to print another line, insert the "continued on next page" instruction, or begin the title on the next page. once the film is generated, it is a simple matter to produce plates for the multilith production of hard copy ( 7). the choice of a ninety-lines-per-page format was influenced, in part, by our desire to use the serials list to break down the reluctance shown by faculty and students toward microformats. this format results in a onethird reduction of the 112-column computer printout and enables our 5,000 current titles to be accommodated on two microfiches ( 152/ pages ). footnotes 1. for the purposes of this article, periodical and serial are synonymous and refer to publications which may be suspended or cease but never conclude. the term "serials list" should be restricted to publications which record only serial titles ( and supplementary information to distinguish between similar titles), holdings, and internal records. library catalogs and union lists are quite sufficient sources for relating a title scientific serial lists /roth 57 to its successor or precedent, and providing full bibliographic detail. 2.

artificial intelligence transistors and other circuit elements of the new generation of computers are so tiny and fitted so closely together that it becomes feasible to combine thinking circuits and memory units on a single chip. thus, one cell in the computer's memory bank can both remember and reason. this is a major step closer to artificial intelligence. in july 1971, the japanese government eannarked $100,000,000 for an eight year study of artificial intelligence. japanese industry accepts the conclusion that it could be increasingly dependent on "intelligent" computers. a technical report dated february 1971 reads; "the development of these tiny chips presages a time when the electronic brain will rival the human brain in complexity and memory. the identity of the fully educated computer may become blurred with that of its programmer-teacher! it may exhibit esthetic and artistic judgments of an interesting degree of subtlety. responses akin to feeling and emotion need not be excluded from its training if they may enhance its performance." along with artificial intelligence will come electronic voice recognition. voice recognition by the computer-in other words, a computer that will respond to oral command-is making significant engineering progress. rca reports that its voice command machine responds to twenty-eight of the basic sounds in the english language.-(extracted from advertising age, march 19, 1973). cbs laboratories invents way to produce microfilm pictures by laser dr. william e. glenn, jr., director of research at cbs laboratories, a division of columbia broadcasting system, inc., has been granted a u.s. patent for an improved method of recording and reproducing information from microfilm. by means of a splitbeam laser, pictorial or printed information is transferred to a metal master. this metal master disk is similar to the type used in the record industry and, from this disk, duplicates can be stamped at low cost. "the market potential," dr. glenn stated, "will not only include the cassette and film industry, but it can be an asset to libraries and government printing as well. this system," he further stated, "is designed for recording and reproducing picture infonnation. it uses diffraction gratings that are modulated in accordance with the picture information. reproduction is effected by directing light through the medium. the zero-order diffracted light is modulated in accordance with the picture information." the patent, assigned to columbia broadcasting system, inc., will offer reduced costs for recording on microfilm. it has potential for use in the motion picture film industry, libraries, and cassette r~ cording. cbs laboratories has made other outstanding advances in laser technology which include the laser color film recorder, holography, and the holographic scanner. l i i 118 journal of library automation vol. 6/ 2 june 1973 microimagery-solution to the information explosion tomorrow's busy businessman will have the information necessary to do his job right at his flngertips, due to the growing acceptance of microimagery as the solution to the information explosion. "in every area of business today, the need for information is increasing faster than any individual can keep up," says walter steel, bell & howell's vice-president of microimagery marketing. "university courses are now teaching kids to be generalists and how to flnd the information on what they need to know. they're learning that the vehicle to the access of information sometimes is more important than the knowledge," steel says. the seventies will be known as the decade of microfilm, just like the sixties for the copier and the fifties for the computer, according to steel. microfilm is halfway between the computer and the copier as a support to business, because it includes copies and peripherals to the computer. soon the copier will become peripheral to microfllm, steel states. steel calls microimagery, "the immediate communication tool." it's the new media that fits the new world of business. soon companies will be saying to their customers, "we11 send you our computer once a week." technical journals will simply send their subscribers a paper newsletter that hits the high spots, along with a deck of microfiche and a new index, plus a retrospective new index each month, steel forecasts. "microfilm won't ever totally replace paper," says steel, "but it will replace file cabinets and storage areas, plus it will simplif,y the filing system in any size office. steel says that the potential for microfilm is greatest in the business records market. the bank market was the base for the microfilm business, but it's no longer predominant, according to steel. "the basic unique value of microimagery is that it saves money. our goal at bell & howell is to be able to provide a complete microfilm system for the small office market for under $1,000. that would include a camera, microfilm processor and viewer," he stated. in light of increasing postage costs, many publishers are actively investigating microimagery. ten pounds of printed matter are reduced in microforms to an ounce or less. with the development of microfiche having a 50 to 1 ratio (i.e., 510 images on a 4 x 6 inch fiche) , 90 percent of the books published could be available on a single microfiche each. the book of the month club could become the fiche of the month club. in every profession there's new technology that the successful manager must have access to in order to continue his success. microimagery can put that knowledge at his fingertips. reports-regional projects and activities new uc library automation office established berkeley-coordination of multicampus automation projects serving the university of california's libraries has been placed in a central office under a director of the university-wide library automation program (ulap). jay l. cunningham, a project manager in uc's institute of library research, has been appointed to the director's position. library automation has been underway for several years at the university of california, which is considered one of the pioneers in this field. each of the nine campus libraries has specialists for automation on its staff, and a central staff has been also working on such problems in the university-wide institute of library research ( ilr) . with growing emphasis on automation, coordination of the various campus projects becomes increasingly important to insure that applications are compatible. uc also maintains close contact with similar efforts at the california state university and colleges. coordination of a number of horary functions by these two segments of public higher education may be greatly facilitated by automated procedures. in recent years, such coordinating tasks have fallen more and more on ilr, an organized research unit directed by a professor in berkeley's school of librarianship, charles p. bourne, who also served as acting ulap director for the past eighteen months. since the primary task of such units is research in support of the university's educational function, the responsibility for development and operation of university-wide automated procedures has been made into a full-time assignment, with cunningham taking over as ulap director from professor bourne. a close working relationship will be maintained between the two groups. among projects well under way are the following: university of california union catalog supplement. the berkeley and ucla catalogs published in book form in 1963 have been recently supplemented by a forty-seven-volume set showing all monographs cataloged by all nine campuses during the five years 1963 through 1967. preparation and printing of the more than 750,000 titles was done by semiautomatic methods. union list af serials. all serial publications, including book series and scholarly journals, to which uc libraries subscribe are entered in another list that is to be continually updated, a task greatly simplified by the computer. scholars and other library users will be able to determine immediately which uc campus subscribes to any serial and how complete its holdings are. bibliographic center. in addition to housing the above two projects, this center helps in processing newly acquired books by printing catalog cards by computer at the ulap headquarters. cards can be ordered by a uc library in full sorted sets, including multiple sets if needed for branch libraries. the new system supplements the present method of ordering cards separately from outside vendors or producing them on each campus. among projects envisaged for the future are automated circulation procedures, under which each borrower would be given a machine-readable card and the charge slip technical communications 119 in the back of the book would likewise be machine-readable, such as a punched card. this method would speed the checking out of books and facilitate statistical studies. other projects include a clearinghouse that would indicate instantaneously whether a new book recommended for purchase has been already ordered by another campus; and the streamlining of library accounting procedures. cunningham is a graduate of cornell university and holds the master of library science degree from berkeley. before joining the ilr staff, he served as a library systems specialist at the library of congress, and as a u.s. air force officer for four years. the new director will report directly to vice-president-academic affairs angus e. taylor, a university-wide official. committee undertakes implementation of program which will afford universitywide "direct access" state university of new york students will soon benefit from more direct access to the 7.5 million books and 6.2 million slides, films, recordings, and other research materials contained in libraries on the university's thirty-four state campuses. that the university is moving to provide faculty and students with walk-in privileges at any of the libraries at the twentynine state-operated campuses and the five statutory colleges at alfred and cornell universities, was announced recently by university chancellor ernest l. boyer. the proposed system, which has the endorsement of the faculty senate of the university, will greatly improve upon the university's current interlibrary loan program under which beaks at cooperating libraries can be borrowed through the mails. working in cooperation with state university librarians, chancellor boyer has announced the formation o£ a committee of librarians and administrators to develop a timetable and procedures to implement the program. the committee will be chaired by willis bridegam, director of libraries at the university center at binghamton. 120 journal of library automation vol. 6/ 2 june 1973 the other members of the panel are dr. philip sirotkin, vice-president for academic ahairs at the university center at albany; don cook of the university center at stony brook; mary cassata of the university center at buffalo; george cornell, college at brockport; and henry murphy of cornell university. in addition to developing a program timetable and procedures, the committee will also explore the future possibility of extending access privileges to the faculty and students at the thirty-eight locallysponsored community colleges. the expanded library access policy is seen as an essential step in the university's efforts to use its library resources more effectively, particularly since the cost of acquiring books and periodicals has grown at an extraordinary rate in recent years. some publications costs have increased at the rate of 15 percent p er year. state university of new york is the first major multicampus system to introduce such a reciprocal program on so wide a scale, although the library system of the state university of illinois has a similar policy, limited to faculty and graduate students. the growing use of modern computer and data processing techniques is another cost control program the university has implemented in administration of its libraries. shared cataloging techniques and the compilation of lists of university-wide locations will be developed to enable library users expeditiously to locate books and reference tools. the policy will be particularly beneficial to students of the university's empire state college, since they are not campusbased and must rely heavily on library collections near their homes or places of employment. the policy will also make it much more convenient for students and faculty to conduct research and complete reference assignments in other parts of the state during vacation and intersession periods. collectively, the libraries at the university's state campuses comprise one of the greatest collections of titles and reference materials in the world. holdings for the 197172 academic year included 7,551,333 volumes, 237,428 microfilms, another 5,115,584 units in other forms of microtext, 20,587 slides, 71,007 recordings, 86,662 maps, 90,694 periodical titles, 29,334 additional serial titles, and 541,007 printed government documents-for a grand total of 13,743,636 entries. potpourri u.s. experts study soviet science information system and services eight united states information specialists from government, universities, professional societies, and private industry participated in the first u.s.-u.s.s.r. symposium on scientific and technical information, organized under the u.s.-u.s.s.r. agreement on cooperation in the fields of science and technology, in moscow, june 18-19. the group led by dr. lee g . burchinal, head, office of science information service, national science f oundation, also spent ten days in the soviet union visiting key information organizations in moscow, novosibirsk, yerevan, and kiev. the purpose of the symposium and subsequent site visits was to give the u.s. group an opportunity to learn more about the soviet system for providing science and industry with needed scientific and technological information, and to explore feasible areas for possible future cooperation. in addition to dr. burchinal, members of the group included william t. knox, director, national technical information service, department of commerce; melvin s. day, deputy director, national library of medicine; dale b. baker, director, chemical abstracts service; scott adams, science communications division, the george washington university; dr. vladimir slamecka, director, school of information and computer science, georgia institute of technology; bart holm, manager, systems development section, information services division, e. i. dupont de nemours & co.; and jerome luntz, senior vice-president, mcgraw-hill publications co. the group was hosted by engineer n. b. arutiunov, director of the information directorate, state committee for science and technology (scst), council of ministers of the u.s.s.r. the symposium featured four presentations by soviet specialists on the following topics: 1. state scientifl.c and technical information system of the u.s.s.r. (dr. 0. v. kedrovskiy) 2. viniti's integrated information system for the u.s.s.r. (dr. a. i. chernyy) 3. specialized system of scientific and technical information services in instrument making (dr. v. a. rukhadze and dr. v. m. baikovsky) 4. psychological aspects in charting the pathways of scientific and technical information development (prof. dr. g. t. artamonov) on june 20-23, the u.s. group visited the all-union institute for scientific and technical information (viniti), the allunion scientific and technical information center (vntitsentr), the all-union research institute of medical and medicotechnical information (vniimi) and the state public library of the u.s.s.r. for science and technology (gpntb-sssr). on june 24-29, the u.s. group visited the siberian branch of the u.s.s.r. academy of sciences and the novosibirsk center of scientific and technical information, the armenian research institute of scientific and technical information and technico-economic studies ( armniinti), the ukrainian research institute of scientific and te chnical information and technico-economic studies (ukrniinti), and the institute of cybernetics of the ukrainian academy of sciences. although about .five years behind the u.s. in applications of technology, especially computer and microform systems, dr. burchinal said, the soviets have established a strong base for rapid future growth. reflecting their style of centralized, national planning, the soviets are well advanced toward development of an integrated national information system embracing both science and technology. the major components of the emerging technical communications 121 integrated national system are { 1) centralized policy, planning review, and methodological guidance provided by the state committee for science and technology ( scst) ; ( 2) concentration of national backup resources in all-union (national) institutions; ( 3) eighty-two ''branch" information networks established by the industrial ministries; ( 4) development by the fifteen republic and regional information institutes of "interbranch" or interdisciplinary dissemination services to serve local industries and planning bodies. a major feature of this national information system is emphasis on the active dissemination ("propaganda") of information about technological innovations throughout the soviet economy. the u.s. group, d. burchinal said, was particularly struck by the importance attached to information services by the highest levels of scientific and technological management in the u.s.s.r. and in the constituent republics. their commitment is reflected in the resources being assigned to development of improved information services. four new buildings are being constructed in moscow alone for all-union scientific and technological information services; staffs are being expanded; third-generation computer systems will be installed at numerous sites beginning in early 197 4; and new buildings are underway or were recently completed for n early a dozen republic and interbranch services. in short, the soviets know where they want to go, and they are devoting considerable resources to achieve their national objectives. the second half of the symposium begun in moscow was held in washington on october 1-2. at that time u.s. and u.s.s.r. representatives sought agreement on areas of continued cooperation which will be reported to the joint u.s.-u.s.s.r. commission on cooperation in science and technology when it meets in moscow. a report of the june visit by the u.s. team to the u.s.s.r. will be available through the national technical information service. 122 journal of library automation vol. 6/2 june 1973 pertinent publications isad cable tv information packet now available from the american library association's information science and

central regional medical library program, dallas, texas trips (talon reporting and information processing system) is an interactive software system for generating reports to nlm on regional medical library network activity and constitutes a vital part of a network management information system (nemis) for the south central regional medical library program. implemented on a pdp-lofsru 1108 interfaced system, trips accepts paper tape input describing network transactions and generates output statistics on disposition of requests, elapsed time for completing filled requests, time to clear unfilled requests, arrival time distribution of requests by day of month, and various other measures of activity andjor performance. emphasized in the trips design are flexibility, extensibility, and system integrity. processing costs, neglecting preparation of input which may be accomplished in several ways, are estimated at $.05 per transaction, a transaction being the transmittal of a message from one library to another. introduction the talon (texas, arkansas, louisiana, oklahoma, and new mexico) regional medical library program is one of twelve regional programs established by the medical library assistance act of 1965. the regional programs form an intermediate link in a national biomedical information network with the national library of medicine ( nlm) at the apex. unlike 214 journal of library automation vol. 4/4 december, 1971 most of the regional programs that formed around a single library, talon evolved as a consortium of eleven large medical resource libraries with administrative headquarters in dallas. a major focus of the talon program is the maintenance of a document delivery service, created in march 1970, to enable rapid access to published medical information. twx units located in ten of the resource libraries and at talon headquarters in dallas comprise the major communication channel. in july 1970 a joint program was initiated to develop a statistical reporting system for the talon document delivery network. design and development of the system was done by the computer science/operations research center at southern methodist university, while training and operational procedures were developed by talon personnel. both parties in the effort view the statistical reporting system as a vital first step in providing talon administrators with a comprehensive network management information system (nemis ). an overview of this statistical reporting system, designated as trips (talon reporting and information processing systems), and its relation to nemis is discussed in the following paragraphs. the objectives and design characteristics of nemis are stated in ( 1 ). design requirements there were two considerations for requirements for a network management information service ( nemis ) for talon: 1) in what environment would talon function? 2) what should be the objectives of a network management information service and what part does a statistical reporting system play in its development? the talon staff and the design team spent an intensive period in joint discussion of these two questions. talon environment the talon document delivery network operates in an expansive geographical area (figure 1). the decentralized structure of the network enables information transfer between any two resource libraries. in addition talon headquarters serves as a switching center, by accepting loan requests, locating documents, and relaying requests to holding libraries. a requirement placed on talon by nlm is the submission of monthly, quarterly, and annual reports giving statistical data on network activity. these statistics provide details on: 1) requests received by channel used (mail, telephone, twx, other), 2) disposition of requests (rejected, accepted and filled , accepted and unfilled), 3) response time for filled requests, 4) response time for unfilled requests, 5) most frequent user libraries, 6) requests received from each of the other regions, and 7) non-medlars reference inquiries. a medical library networkjnance 215 • fig. 1. location of the eleven resource libraries and talon headquarters. monthly reports require cumulative statistics on year-to-date performance, and each of the eleven resource libraries and talon headquarters is required to submit a report on its activity. needs and objectives while the immediate need of the talon network was to develop a system to eliminate manual preparation of nlm reports, an initial decision was made to develop software also capable of assisting talon management in policy and decision making. eventual need for a network management information system ( nemis) being recognized, the talon reporting and information processing system (trips) was designed as the first step in the creation of nemis. provision of information in a form suitable for analytical studies of policy and decision makinge.g., the message distribution problem described by nance ( 2) -placed some stringent requirements on trips. for instance, the identification of primitive data elements could not be made from report considerations only; an overall decision had to be made that no sub-item of information would ever be required for a data element. in addition the system demanded flexibility and extensibility, since it was to operate in a highly dynamic environment. these characteristics are quite apparent in the design of trips. 216 journal of library automation vol. 4/4 december, 1971 trips design trips is viewed as a system consisting of hardware and software components. the description of this system considers: 1) the input, 2) the software subsystems (set of programs), 3) hardware components, and 4) the output. emphasis is placed on providing an overview, and no effort is made to give a detailed description. the environment in which trips is to operate is defined in a single file ( for25.dat). this file assigns network parameters, e.g., number of reporting libraries, library codes, and library titles. the file is accessed by subprograms written in fortran iv and dystal ( 3), the latter being a set of fortran iv subprograms, termed dystal functions, that perform primitive list processing and dynamic storage allocation operations. because it requires only fortran iv trips can be implemented easily on most computers. input a transaction log, maintained by each regional library and talon headquarters, constitutes the basic input to trips. copies of log sheets are used to create paper tape description of the transactions. if and when compatibility is achieved between standard twx units and telephone entry to computer systems, the input could be entered directly by each regional library. (this is technically possible at present. ) currently, talon headquarters is converting the transaction descriptions to machine readable form. initial data entry under normal circumstances is pictured in figure 2, which shows the sequence of operations and file accesses in two phases: 1) data entry and 2) report generation. data entry in tum comprises 1) collecting statistics, 2) diagnosis and verification of input data and 3) backup of original verified input data. trips is designed to be extremely sensitive to input data. all data is subjected to an error analysis, and a specific file (for22.dat ) is used to collect errors detected or diagnosed in the error analysis routine. only verified data records are transmitted to the statistical accumulation file (for20.dat). software subsystems trips comprises seven subsystems or modules. within each module are several fortran iv subprograms, dystal function and/ or pdp-10 systems programs discussed under hardware components in the following section: newy: run at the beginning of each year, newy builds an in-core data structure and transfers it to disk for each resource library in the network. it further creates the original data backup disk file ( for23.dat). after disk formatting , record (the accessing and storage module) may be activated to begin accumulating statistics for the new year. a medical library

run between quarters, newq purges the past quarter statistics for each library and prepares file for23.dat for the next quarter. the report for the quarter must be generated before newq is executed. run between months, newm purges the monthly statistics for each regional library and prepares file for23.dat for the backing up of next month's data. the utility module causes a dyst al dump of the data base. the accessing and storage module record incorporates the error diagnosis on input and the entry of validated data records into file for23.dat. no data record with an indicated error is permitted, and erroneous records are flagged for exception reporting. the error report (ermes.dat) may be printed on the teletype or line printer after execution of record. the reporting module report generates all reimbursable statistics on a month-to-date, quarter-to-date, and year-todate basis. utilization of trips as a network management tool is afforded by manage, which combines statistics from reimbursable and non-reimbursable transactions to generate a report providing measures of total network activity and performance. 218 journal of library automation vol. 4/4 december, 1971 the

system integrity. in addition to the diagnosis of input data, trips concatenates sequential copies of disk file for23.dat to provide a magnetic tape backup containing all valid data records for the current year. a failsafe tape, containing all trips programs, is also maintained. hardware components conversion of transaction information to machine readable form is done off line currently. using a standard twx with ascii code, paper tapes are created and spliced together. fed through a paper tape reader to a pdp-10 (digital equipment company), the input data is submitted to trips. control of trips is interactive, with the user monitoring program execution from a teletype. all file operations are accomplished using the pdp-10 via the teletype, and the output reports are created on a high-speed line printer. with sm,u's pdp-10 and sru 1108 interface, report generation can be done on line printers at remote terminals to the sru 1108 as well. output trips output consists of a report for each library in the network and a composite for the entire network. the report may be limited to reimbursable statistics or include all statistics. information includes: 1) errors encountered in the input phase, 2) number of requests received by channel, 3 ) disposition of requests (i.e., rejected, accepted/ filled, accepted/ unfilled, etc. ) , 4) elapsed time for completing :filled requests or clearing unfilled requests, 5) geographic origin of requests, 6) titles for which no holdings were located within the region, 7 ) types of requesting institutions, 8) arrival time distribution of requests by day of month, 9) invoice for reimbursement by talon, 10 ) node/ network dependency coefficient as described by ( 4). summary trips is now entering its operational phase. training of personnel at the resource libraries is concluded, and data on transactions are being entered into the system. input errors have decreased significantly ( from fifteen or twenty percent to approximately two percent ). talon personnel are enthusiastic, and needless to say the regional library staffs are happy to see a bothersome, time-consuming manual task eliminated. in summary, the following characteristics of trips deserve repeating: 1) with its modular construction, it is flexible and extensible. 220 journal of library automation vol. 4/4 december, 1971 2) implemented in dystal and fortran iv, it should allow installation on most computers without major modifications. 3) designed to operate in an interactive environment, it can be modified easily to function in a batch processing environment. 4) trips is extremely sensitive to system integrity, providing diagnosis of input data, reporting of errors, magnetic tape backup of data files, and a system failsafe tape. 5) definition of primitive data elements and the structural design of trips enable it to serve as the nucleus of a network management information system ( nemis) as well as to generate reports required by nlm. 6) currently accepting paper tape as the input medium, trips could be modified easily to accept punched card input and with more extensive changes could derive the input information during the message transfer among libraries. finally, the processing cost of operating trips, neglecting the conversion to paper tape, is estimated to be $.05 per transaction (a message transfer from one library to another). extensive and thorough documentation of trips has been provided. availability of this documentation is under review by the funding agency. acknowledgment work described in

tomasz neugebauer and bin han information technology and libraries | march 2012 113 abstract this paper describes the batch importing strategy and workflow used for the import of theses metadata and pdf documents into the eprints digital repository software. a two-step strategy of importing metadata in marc format followed by attachment of pdf documents is described in detail, including perl source code for scripts used. the processes described were used in the ingestion of 6,000 theses metadata and pdfs into an eprints institutional repository. introduction tutorials have been published about batch ingestion of proquest metadata and electronic theses and dissertations (etds),1 as well as endnote library,2 into the digital commons platform. the procedures for bulk importing of etds using dspace have also been reported.3 however, bulk importing into the eprints digital repository software has not been exhaustively addressed in the literature.4 a recent article by walsh provides a literature review of batch importing into institutional repositories.5 the only published report on batch importing into the eprints platform describes perl scripts for metadata-only records import from thomson reuters reference manager.6 bulk importing is often one of the first tasks after launching a repository, so it is unsurprising that requests for reports and documentation on eprints-specific workflow have been a recurring question on the eprints tech list.7 a recently published review of eprints identifies “the absence of a bulk uploading feature” as its most significant weakness.8 although eprints’ graphical user interface for bulk importing is limited to the use of the installed import plugins, the software does have a versatile infrastructure for this purpose. leveraging eprints’ import functionality requires some perl scripting, structuring the data for import, and using the command line interface. in 2009, when concordia university launched spectrum,9 its research repository, the first task was a batch ingest of approximately 6,000 theses dated from 1967 to 2003. the source of the metadata for this import consisted in marc records from an integrated library system powered by innovative interfaces and proquest pdf documents. this paper is a report on the strategy and workflow adopted for batch ingestion of this content into the eprints digital repository software. import strategy eprints has a documented import command line utility located in the /bin folder.10 documents can also be imported through eprints’ graphical interface. using the command line utility for tomasz neugebauer (tomasz.neugebauer@concordia.ca) is digital projects and systems development librarian and bin han (bin.han@concordia.ca) is digital repository developer, concordia university libraries, montreal, quebec, canada. mailto:tomasz.neugebauer@concordia.ca mailto:bin.han@concordia.ca batch ingesting into eprints digital repository software| neugebauer and han 114 importing is recommended because it is easier to monitor the operation in real time by adding progress information output to the import plugin code. the task of batch importing can be split into the following subtasks: 1. import of metadata of each item 2. import of associated documents, such as full-text pdf files the strategy adopted was to first import the metadata for all of the new items into the inbox of an editor’s account. after this first step was completed, a script was used to loop through the newly imported eprints and attach the corresponding full-text documents. although documents can be imported from the local file system or via http, import of the files from the local file system was used. the batch import procedure varies depending on the format of the metadata and documents to be imported. metadata import requires a mapping of the source schema fields to the default or custom fields in eprints. the source metadata must also be converted into one of the formats supported by eprints’ import plugins, or a custom plugin must be created. import plugins are available for many popular formats, including bibtex, doi, endnote, and pubmedxml. in addition, community-contributed import plugins such as marc and arxiv are available at eprints files.11 since most repositories use custom metadata fields, some customization of the import plugins is usually necessary. marc plugin for eprints in eprints, the import and export plugins ensure interoperability of the repository with other systems. import plugins read metadata from one schema and load it into the eprints system through a mapping of the fields into the eprints schema. loading marc-encoded files into eprints requires the installation of the import/export plugin developed by romero and miguel.12 the installation of this plugin requires the following two cpan modules: marc::record and marc::file::usmarc. the marc plugin was then subclassed to create an import plugin named “concordia theses,” which is customized for thesis marc records. concordia theses marc plugin the marc plugin features a central configuration file (see appendix a) in which each marc field is paired with a corresponding mapping to an eprints field. most of the fields were configured through this configuration file (see table 1). the source marc records from the innovative interfaces integrated library system (ils) encode the physical description of each item using the anglo american cataloguing rules, as in the following example: “ix, 133 leaves : ill. ; 29 cm.” since the default eprints field for number of pages is of the type integer and does not allow multipart physical descriptions from the marc 300 field, a custom text field for these physical descriptions (pages_aacr) had to be added. the marc.pl configuration file cannot be used to map compound fields, such as author names—the fields need custom mapping implementation in perl. for instance, the marc 100 and 700 fields information technology and libraries | march 2012 115 are transferred into the eprints author compound field (in marc.pm). similarly, marc 599 is mapped into a custom thesis advisor compound field. marc field

publication table 1. mapping table from marc to eprints helge knüttel’s refinements to the marc plugin shared on the eprints tech list were employed in the implementation of a new subclass of marc import for the concordia theses marc records. in the implementation of the concordia theses plugin, concordiatheses.pm inherits from marc.pm. (see figure 1.)13 knüttel added two methods that make it easier to subclass the general marc plugin and add unique mappings: handle_marc_specialities and post_process_eprint. the post_process_eprint function was not used to attach the full-text documents to each eprint. instead, the strategy to import the full-text documents using a separate attach_documents script was used (see “theses document file attachment” below). import of all of the specialized fields, such as thesis type (mapped from marc 710t), program, department, and proquest id, was implemented in the function handle_marc_specialities of concordiatheses.pm. for instance, 502a in the marc record contains the department information, whereas an eprints system like spectrum stores department hierarchy as subject objects in a tree. therefore importing the department information based on the value of 502a required regular expression searches of this marc field to find the mapping into a corresponding subject id. this was implemented in the handle_marc_specialities function. batch ingesting into eprints digital repository software| neugebauer and han 116 figure 1. concordia theses class diagram, created with the perl module uml::class::simple execution of the theses metadata import the depositing user’s name is displayed along with the metadata for each eprint. a batchimporter user with the corporate name “concordia university libraries” was created to carry out the import. as a result, the public display of the imported items shows the following as a part of the metadata: “deposited by: concordia university libraries.” the marc plugin requires the encoding of the source marc files to be utf-8, whereas the records are exported from the ils with marc-8 encoding. therefore marcedit software developed by reese was used to convert the marc file to utf-8.14 to activate the import, the main marc import plugin and its subclass, concordiatheses.pm, have to be placed in the plugin folder /perl_lib/eprints/plugin/import/marc/. the configuration file information technology and libraries | march 2012 117 (see appendix a) must also be placed with the rest of the configurable files in /archives/repositoryid/cfg/cfg.d. the plugin can then be activated from the command line using the import script in the /bin folder. a detailed description of this script and its usage is documented on the eprints wiki. the following eprints command from the /bin folder was used to launch the import: import repositoryid --verbose --user batchimporter eprint marc::concordiatheses theses-utf8.mrc following the aforementioned steps, all the theses metadata was imported into the eprints software. the new items were imported with their statuses set to inbox. a status set to inbox means that the imported items are in the work area of batchimporter user and will need to be moved to live public access by switching their status to archive. theses document file attachment after the process of importing the metadata of each thesis is complete, the corresponding document files need to be attached. the proquest id was used to link the full-text pdf documents to the metadata records. all of the marc records contained the proquest id, while the pdf files, received from proquest, were delivered with the corresponding proquest id as the filename. the pdfs were uploaded to a folder on the repository web server using ftp. the attach_documents script (see appendix b for source code) was then used to attach the documents to each of the imported eprints in the batchimporter’s inbox and to move the imported eprints to the live archive. several variables need to be set at the beginning of the attach_documents operation (see table 2). variable comment $root_dir = 'bin/importdata/proquest' this is the root folder where all the associated documents are uploaded by ftp. $depositor = 'batchimporter' only the items deposited by a defined depositor, in this case batchimporter, will be moved from inbox to live archive. $dataset_id = 'inbox' limit the dataset to those eprints with status set to inbox $repositoryid = 'library' the internal eprints identifier of

contain a corresponding document file. a list of eprint ids of theses that did not contain a corresponding full-text pdf document are listed at the end of the log file, along with the count of the number of theses that were made live. after the import operation is complete, all the abstract pages need to be regenerated with the following command: /bin/generate_abstracts repositoryid conclusions this paper is a detailed report on batch importing into the eprints system. the authors believe that this paper and its accompanying source code is a useful contribution to the literature on batch importing into digital repository systems. in particular, it should be useful to institutions that are adopting the eprints digital repository software. batch importing of content is a basic and fundamental function of a repository system, which is why the topic has come up repeatedly on the eprints tech list and in a repository software review. the methods that we describe for carrying out batch importing in eprints make use of the command line and require perl scripting. more robust administrative graphical user interface support for batch import functions would be a useful feature to develop in the platform. acknowledgements the authors would like thank mia massicotte for exporting the metadata records from the integrated library system. we would also like to thank alexandros nitsiou, raquel horlick, adam field, and the reviewers at information technology and libraries for their useful comments and suggestions. references 1. shawn averkamp and joanna lee, “repurposing

(jeremy.myntti@utah.edu) is head of digital library services, university of utah. abstract this article discusses the burgeoning “collections as data” movement within the fields of digital libraries and digital humanities. faculty at the university of utah’s marriott library are developing a collections as data strategy by leveraging existing digital library and digital matters programs. by selecting various digital collections, smalland large-scale approaches to developing open datasets are explored. five case studies chronicling this strategy are reviewed, along with testing the datasets using various digital humanities methods, such as text mining, topic modeling, and gis (geographic information system). introduction for decades, academic research libraries have systematically digitized and managed online collections for the purpose of making cultural heritage objects available to a broader audience. making archival content discoverable and accessible online has been revolutionary for the democratization of scholarship, but the use of digitized collections has largely mimicked traditional use: researchers clicking through text, images, maps, or historical documents one at a time in search of deeper understanding. “collections as data” is a growing movement to extend the research value of digital collections beyond traditional use and to give researchers more flexible access to our collections by facilitating access to the underlying data, thereby enabling digital humanities research.1 collections as data is predicated upon the convergence of two scholarly trends happening in parallel over the past several decades.2 first, as mentioned above, librarians and archivists have digitized a significant portion of their special collections, giving access to unique material that researchers previously had to travel across the country or globe to study. at the same time, an increasing number of humanist scholars have approached their research in new ways, employing computational methods such as text mining, topic modeling, gis (geographic information system), sentiment analysis, network graphs, data visualization, and virtual/augmented reality in their quest for meaning and understanding. gaining access to high-quality data is a key challenge of digital humanities work, since the objects of study in the humanities are frequently not as amenable to computational methods as data in the sciences and social sciences.3 typically, data in the sciences and social sciences is numerical in nature and collected in spreadsheets and databases with the intention that it will be computationally parsed, ideally as part of a reproducible and objective study. conversely, data (or, more commonly, “evidence” or “research assets”) in the humanities is textor image-based and is created and collected with the intention of close reading or analysis by a researcher who brings their subjective expertise to bear on the object.4 even a relatively simple digital humanities method like identifying word frequency in a corpus of literature is predicated on access to plain mailto:rachel.wittmann@utah.edu

https://doi.org/10.6017/ital.v38i4.11101 text (.txt) files, high-quality optical character recognition (ocr), and the ability to bulk download the files without running afoul of copyright or technical barriers. as “the santa barbara statement on collections as data” articulates, “with notable exceptions like the hathitrust research center, the national library of the netherlands data services & api’s, the library of congress’ chronicling america, and the british library, cultural heritage institutions have rarely built digital collections or designed access with the aim to support computational use.”5 by and large, digital humanists have not been well-served by library platforms or protocols. current methods for accessing collections data include contacting the library for direct access to the data or “scraping” data off library websites. recently funded efforts such as the institute of museum and library services’ (imls’s) always already computational and the andrew w. mellon foundation’s collections as data: part to whole seek to address this problem by setting standards and best practices for turning digital collections into datasets amenable to computational use and novel research methods.6 the university of utah j. willard marriott library has a long-running digital library program and a burgeoning digital scholarship center creating a moment of synergy for librarians in digital collections and digital scholarship to explore collaboration in teaching, outreach, and digital collection development. a shared goal between the digital library and digital scholarship teams is to develop collections as data of regional interest that could be used by researchers for visualization and computational exploration. this article will share our local approach to developing and piloting a collections as data strategy at our institution. relying upon best practices and principles from thomas padilla’s “on a collections as data imperative,” we transformed five library collections into datasets, made select data available through a public github repository, and tested the usability of the data with our own research questions relying upon expertise and infrastructure from digital matters and the digital library at the marriott library.7 digital matters in 2015, administration at the marriott library was approached by multiple colleges at the university of utah to explore the possibility of creating a collaborative space to enable digital scholarship. while digital scholarship was happening across campus in disparate and unfocused ways, there was no concerted effort to share resources, build community, or develop a multi-college digital scholarship center with a mission and identity. after an eighteen-month planning process, the digital matters pop-up space was launched as a four-college partnership between the college of humanities, college of fine arts, college of architecture + planning, and the marriott library. an anonymous $1 million donation in 2017 allowed the partner colleges to fund staffing and activity in the space for five years, including the hire of a digital matters director tasked with planning for long-term sustainability. the development of digital matters brings new focus, infrastructure, and partners for digital humanities research to the university of utah and the marriott library. monthly workshops, speakers, and reading groups led by digital scholars from all four partner colleges have created a vibrant community with crossdisciplinary partnerships and unexpected synergies. close partnerships and ongoing dialogue have increased awareness for marriott faculty, particularly those working in and collaborating with digital matters, of the challenges facing digital humanists and the ways in which the library community is uniquely suited to meet those needs. for example, a university of utah researcher in the college of humanities developed “century of black mormons,” a community-based public history database of biographical information and primary source documents on black mormons baptized between 1830 and 1930.8 working closely with the digital initiatives librarian and various staff and faculty at the marriott library, they created an omeka s site that allows users to interact with the historical data using gis, timeline features, and basic webpage functionality. information technology and libraries | december 2019 51 institution digital library the university of utah has had a robust digital library program since 2000, including one of the first digital newspaper repositories, utah digital newspapers (udn, https://digitalnewspapers.org/). in 2016, the library developed its own digital asset management system using open-source systems such as solr, phalcon, and nginx after using contentdm for over fifteen years.9 this new system, solphal, has made it possible for us to implement a custom solution to manage and display a vast amount of digital content, not only for our library, but also for many partner institutions throughout the state of utah. our main digital library server (https://collections.lib.utah.edu/) contains over 765,000 objects in nearly 700 collections, consisting of over 2.5 million files. solphal is also used to manage the udn, containing nearly 4 million newspaper pages and over 20 million articles. digital library projects are continually evolving as we redefine our digital collection development policies, ensuring that we are providing researchers and other users the digital content that they are seeking. with such a large amount of data available in the digital library, we can no longer view our digital library as a set of unique, yet siloed, collections, but more as a wealth of information documenting the history of the university, the state of utah, and the american west. we are also engaged in remediating legacy metadata across the repository in order to achieve greater standardization, which could support computational usage of digital library metadata in the future. with this in mind, we are working to strategically make new digital content available on a large scale that can help researchers discover this historical content within a collections as data mindset. leveraging the existing digital library and digital matters programs, faculty at the marriott library are in the process of piloting a collections as data strategy. we selected digital collections with varying characteristics and used them to explore smalland large-scale approaches to developing datasets for humanities researchers. we then tested the datasets by employing various digital humanities methods such as text mining, topic modeling, and gis. the five case studies below chronicle our efforts to embrace a collections as data framework and extend the research value of our digital collections. text mining mining texts when developing the initial collections as data project, several factors were considered to identify the optimal material for this experiment. selecting already digitized and described material in the university of utah digital library was ideal to avoid waiting periods required for new digitization projects. the marriott library special collections’ relationship with the american west center, an organization based at the university of utah with the mission of documenting the history of the american west, has produced an extensive collection of oral histories held in the audio visual archive which have typewritten transcripts yielding high-quality ocr. given the availability and readiness of this material, we built a selected corpus of mining-related oral histories, drawn from collections such as the uranium oral histories and carbon county oral histories. engaging in the entire process with a digital humanities framework, we scraped our own digital library repository as though we had no special access to the back end of the system, developing a greater understanding of the process and workflows needed to build a text corpus to support a research inquiry. in this way, we extended our skills so that we would be able to scrape any digital library system if this expertise was needed in the future. the extensive amount of text produced by the corpus of 230 combined oral histories provided ideal material for topic modeling. simply put, “topic modeling is an automatic way to examine the contents of a corpus of documents.”10 the output of these models is word clouds with varying sizes of words based on the number of co-occurrences within the corpus; larger words indicate more occurrences and smaller ones indicate fewer. each topic model then points to the most relevant documents within the corpus based on the co-occurrences of the words contained in that model. in order to create these topic models from the https://digitalnewspapers.org/ https://collections.lib.utah.edu/ from digital library to open datasets | wittmann, neatrour, cummings, and myntti 52 https://doi.org/10.6017/ital.v38i4.11101 corpus of oral histories, a workflow was developed with the expertise of the digital matters cohort, implementing mallet for r script, using the lda topic model style, developed by blei et al.11 figure 1. topic model from text mining the mining-related oral histories found in the university of utah’s digital library. from the mining-related oral history corpus, twenty-six topic models were created. once generated, each topic model points to five interviews that are most related to the words in a particular model. in figure 1, the words carbon, county, country, and italian are the largest, because the interviews are about carbon county, utah. considering this geographical area of utah was the most ethnically diverse in the late 1800s due to the coal mining industry recruiting labor from abroad, including italy, these words are not surprising. as indicated by their prominence in the topic model, the set of words co-occur most often in the interview set. we approached the process of topic modeling the oral histories as an exploration, but after information technology and libraries | december 2019 53 reviewing the results, we discovered that many of the words which surfaced through this process pointed to deficiencies in the original descriptive metadata, highlighting new possibilities for access points and metadata remediation. honing in on the midsize words tended to uncover unique material that is not covered in descriptive metadata, as these words are often mentioned more than a handful of times and across multiple interviews. the largest words in the model are typically thematic to the interview and included in the descriptive metadata. for example, when investigating the inclusion of “wine” in the topic model found in figure 1, conversations about the winemaking process amongst the italian mining community in carbon county, utah were revealed. from an interview with mary nicolovo juliana conducted in 1973 from the carbon county oral history project, nicolovo discusses how her father, a miner, made wine at home.12 as the topic models are based on co-occurrences in the corpus, there was another interview with emile louise cances, from the carbon county oral history project conducted in 1973. cances, from a french immigrant mining family, discusses the vineyards her family had in france.13 with both of these oral histories, there was no reference to wine in the descriptive metadata. a researcher may miss this content because it isn’t included as an access point in metadata. thus, topic modeling allowed for the discoverability of potentially valuable topics that may be buried in hundreds of pages of content. from this collections as data project, text mining the mining oral history texts to produce topic models, we are considering employing topic modeling when creating new descriptive metadata for similar collections. setting a precedent, the text files for this project are hosted on the growing marriott library collections as data github repository. after we developed this corpus, we discovered that a graduate student in the history department had developed a similar project, demonstrating the research value of oral histories combined with computational analysis.14 harold stanley sanders matchbooks collection when assessing potential descriptive metadata for the harold stanley sanders matchbooks collection, an assortment of matchbooks that reflect many bygone establishments predominately from salt lake city that include restaurants, bars, hotels, and other businesses, non-dublin core metadata was essential for computational purposes. with the digital project workflow now extending beyond publishing the collection in the digital library, to publishing the collection data to the marriott library collections as data github repository, assessing metadata needs has evolved. as matchbooks function as small advertisements, they often incorporate a mix of graphic design, advertising slogans, and addresses of the establishment. the descriptive metadata was created first with the most relevant fields for computational analysis, including business name, type of business, transcription of text, notable graphics, colors of matchbooks, and street addresses. for collection mapping capabilities, street addresses were then geocoded using a google sheets add-on called geocode cells, which uses google’s geocoding api (see figure 2). from digital library to open datasets | wittmann,

https://chrome.google.com/webstore/detail/geocode-cells/pkocmaboheckpkcbnnlghnfccjjikmfc information technology and libraries | december 2019 55 this proved efficient for this collection, as other geocoding services required zip codes for street addresses which were not present on the matchbooks. with the latitude and longitude addition to the metadata, the collection was then mapped using arcgis online (see figure 3).15 the extensive metadata, including geographic-coordinate data, is available on the library’s github repository for public use. after the more computationally ready metadata was created, it was then massaged to fit library best practices and dublin core (dc) standards. this included deriving library of congress subject headings for dc subjects from business type and concatenating notable matchbook graphics and slogans for the dc description. while providing the extensive metadata is beneficial for computational experimentation, it adds time and labor to the lifespan of the project. kennecott copper miner records one aspect of our collections as data work at the university of utah moving forward is the need for longterm planning for resources that contain interesting information that could eventually be used for computational exploration, even if we currently don’t have the capacity to make the envisioned dataset available at the current time. the marriott library holds a variety of personnel records from the kennecott copper corporation, utah copper division. these handwritten index cards contain a variety of interesting demographic data about the workers who were employed by the company from 1900-19 such as name, employee id, date employed, address, dependents, age, weight, height, eyes, hair, gender, nationality, engaged by, last employer, education, occupation, department, pay rate, date leaving employment, and reason for leaving. not all the cards are filled out with the complete level of detail as listed in the fields above, however, usually name, date employed, ethnicity, and notes about pay rates for each employee are included. developing a scanning and digitization procedure for creating digital surrogates of almost 40,000 employment records was fairly easy due to an existing partnership and reciprocal agreement with familysearch, however developing a structure for making the digitized records available and providing full transcription is a long-term project. librarians used this project as an opportunity to think strategically about the limits of dublin core when developing a collections as data project from the start. the digital library repository at the university of utah provides the ability to export collection level metadata as .tsv files. with this in mind, the collection metadata template was created with the aim of eventually being able to provide researchers with the granular information on the records. this required introducing a number of new, non-standard field labels to our repository. since we are not able to anticipate exactly how a researcher might interact with this collection in the future, our main priority was developing a metadata template that would accommodate full transcription for every data point on the card. twenty new fields in the template reflect the demographic data on the card, and ten are existing fields that map to our standard practices with dublin core fields. because we do not currently have the staffing in place to transcribe 40,000 records, we are implementing a phased approach of transcribing four basic fields, with fuller transcription to follow if we are able to secure additional funding. from digital library to open datasets | wittmann, neatrour, cummings, and myntti 56 https://doi.org/10.6017/ital.v38i4.11101

matters is to be a digital humanities space that is unique to utah and addresses issues of local significance such as public lands, water rights, air quality, indigenous peoples, and mormon history.16 when considering what digital scholarship projects to pursue in 2019, digital matters faculty became aware of the upcoming 150th anniversary of women in utah being the first to vote in the nation. working with a local nonprofit, better days 2020, and colleagues at brigham young university (byu), digital matters faculty and staff decided to embark on a multimodal analysis of the 6,800-page run of the woman’s exponent, a utah women’s newspaper published between 1872-1914 primarily under the leadership of latter-day saint relief society president emmeline b. wells. in its time, the woman’s exponent was a passionate voice for women’s suffrage, education, and plural marriage, and chronicled the interest and daily lives of latter-day saint women. initially, we hoped to access the data through the brigham young university harold b. lee library, which digitized the exponent back in 2000. we quickly learned that ocr from nearly twenty years ago would not suffice for digital humanities research and considered different paths for rescanning the exponent. after accessing the original microfilm from byu, we leveraged existing structures for digitization. through an agreement that the marriott library has in place with a vendor for completing large-scale digitization of newspapers on microfilm for inclusion in the utah digital newspapers program, we were able to add the woman’s exponent to the existing project without securing a new contract for digitization. the vendor digitized the microfilm, created an index of each title, issue, date, and page, and extracted the full text from digital library to open datasets | wittmann, neatrour, cummings, and myntti 58 https://doi.org/10.6017/ital.v38i4.11101 through an ocr process. they then delivered 330 gb of data to us, including high-quality tiff and jp2000 images, a pdf file for each page, and mets-alto xml files containing the metadata and ocr text. acquiring data for the woman’s exponent project illuminated the challenges that digital humanists face when looking for clean data. our original assumption was that if something had already been scanned and put online, the data must exist somewhere. we soon learned, when working with legacy digital scans, that the ocr might be insufficient or the original high-quality scans might be lost over the course of multiple system migrations. as librarians with existing structures in place for digitization, we had the content rescanned and delivered within a month. our digital humanities partners from outside of the library did not know this option was available and assumed our research team would have to scan 6,800 pages of newspaper content before we were able to start analyzing the data. this incongruity highlighted cultural differences between digital humanists with their learned self-reliance and librarians who are more comfortable and conversant looking to outside resources. indeed, our digital humanities colleagues seemed to believe that “doing it yourself” was part and parcel of digital humanities work. the woman’s exponent project is still in early phases, but now that we have secured the data, we are considering what digital humanities methods we can bring to bear on the corpus. with the 2020 150th anniversary of women’s suffrage in utah, we have considered a topic modeling project looking at themes around universal voting, slavery, and polygamy and tracking how the discussion around those topics evolved over the 42-year run of the paper. another potential project is building a social network graph of the women and men chronicled throughout the run of the paper. developing curriculum around women in utah history is of particular interest to the group as women are underrepresented in the current k-12 utah history curriculum. keeping in line with our commitment to collections as data, we have released the woman’s exponent as a .tsv file with ocr full-text data, which can be analyzed by researchers studying utah, mormon studies, the american west, or various other topics. collaborators have also developed a digital exhibit on the woman’s exponent which includes essays about a variety of topics as well as sections showcasing its potential for digital scholarship.17 obituary data the utah digital newspapers (udn) program began in 2002 with the goal of making historical newspaper content from the state of utah freely available to the public for research purposes. between 2002 and 2019, there have been over 4 million newspaper pages digitized for udn. due to search limitations of the software system used for udn at the time, the data model for newspapers was made more granular, and included segmentation for articles, obituaries, advertisements, birth notices, etc. this article segmentation project ended in 2016 when it was determined that the high cost of segmentation was not sustainab le with mass digitization of newspapers and users were still able to find the content they are looking for on a full newspaper page. before the article segmentation project concluded, udn had accrued over 20 million articles, including 318,044 articles that were tagged as obituaries or death notices. in 2013, the marriott library partnered with familysearch to index the genealogical information that can be gleaned from these obituaries. the familysearch indexing (fsi) program crowdsourced the indexing of this data to thousands of volunteers worldwide. certain pieces of data, such as place names, were mapped to an existing controlled vocabulary and dates were entered in a standardized format to ensure that certain pieces of the data are machine actionable.18 after the obituaries were indexed by fsi in 2014, a copy of the data was given to the marriott library to use in udn. the indexed data included fields such as name of deceased, date of death, place of death, date of birth, birthplace, and relative names with relationships. since this massive amount of data didn't easily fit within the udn metadata schema, it was stored for several years without the marriott library doing anything with the data. information technology and libraries | december 2019 59 now that we are thinking about our digital collections as data, we are exploring ways that researchers could use this vast amount of data. the data was delivered to the library in large spreadsheets that are not easily usable in any spreadsheet software. we are exploring ingesting the data into a revised newspaper metadata schema within our digital asset management system or converting the data into a mysql database so it is possible to search and find relationships between pieces of data. working with a large dataset such as this can be challenging. the data from only two newspapers, including 1,038 obituaries, is a 25 mb file. the full database is over 10 gb of data. since this is a large amount of data, we are working through issues related to how we can distribute this data in a usable way in order for researchers to make use of the data. we are also looking at the possibility of having fsi index a dditional obituary data from udn, which will make the database continually expand. conclusion as the digital library community recognizes the need for computational-ready collections, the university of utah digital library has embraced this evolution with a strategic investment. implementing the collections as data github repository for computational users is a first step towards providing access to collections beyond the traditional digital library environment. while there may be improved ways to access this digital library data in the future, the github repository filled an immediate need. developing standardized metadata for computational use can often require more time from metadata librarians who are already busy with the regular work of describing new assets for the digital library. developing additional workflows for metadata enhancement and bulk download can delay the process in making new collections available. in most cases, collections need to be evaluated individually to determine what type of resources can be invested in making them available for computational use. for a project needing additional transcription, like the kennecott mining records, crowdsourcing might seem like potential avenue to pursue. however, the digital library collection managers have misgivings about the training and quality assurance involved in developing a new large-scale transcription project. combined with the desire to ensure that the people who are working on the project have adequate training and compensation for their labor, we are making the strategic decision to transcribe for some of the initial access points to the collection now, and attempt full transcription at a later date pending additional funding. for the udn obituary data, leveraging an existing transcription program at no cost with minimal supervision needed by librarians worked well in being able to surface additional genealogical data that can be released for researchers. the collections as data challenge mirrors a perennial digital library conundrum—how much time and effort should librarians invest for unknown future users with unknown future needs? much like digitization and metadata creation, creating collections as data requires a level of educated guesswork as to what collections digital humanists will want to access, what metadata fields they will be interested in manipulating, and in what formats they will need their data. considering the limited resources of librarians, should we convert our digital collections into data in anticipation of use or convert our collections on demand? this “just in case” vs. “just in time” question is worthy of debate and will naturally be dependent on the resources and priorities of individual institutions. with an increasing number of researchers experimenting with digital humanities methods, collections as data will be a standard consideration when working with new digitization projects at the university of utah. visualization possibilities outside of the digital-library environment will be regularly assessed. descriptive metadata practices beyond dublin core will be developed when beneficial to the computational and experimental use of the data by the public. integrating techniques like topic modeling into descriptive metadata workflows provides additional insight about the digital objects being described. while adding collections as data to existing digitization workflows will require an additional investment of time, developing these projects has also created new opportunities for collaboration both within the library and from digital library to open datasets | wittmann, neatrour, cummings, and myntti 60 https://doi.org/10.6017/ital.v38i4.11101 in developing expanded partnerships at the university of utah and other institutions in the mountain west. by leveraging our existing partnerships, we were able to create collections as data pilots organically by taking advantage of our current workflows and digitization procedures. while we have been successful in releasing smaller-scale collections as data projects, we still need to consider integration issues with our larger digital library program and experiment more with enabling access to large datasets. with librarians engaged in producing curated datasets that evolve from unique special collection materials, they can extend the research value of the digital library and the collections that are unique to each institution. as we look towards the future, we see this work continuing and expanding as librarians engage more with digital humanities teaching and support. acknowledgements the authors would like to acknowledge

163 ■■ the space in between in my opinion, ital has an identity crisis. it seems to try in many ways to be scholarly like jasist, but lita simply isn’t as formal a group as asist. on the other end of the spectrum, code4lib is very dynamic, informal and community-driven. ital kind of flops around awkwardly in the space in between. —comment by a respondent to ital’s reader survey, december 2009 last december and january, you, the readers of information technology and libraries were invited to participate in a survey aimed at helping us to learn your likes and dislikes about ital, and where you’d like to see this journal go in terms of several important questions. the responses provide rich food for reflection about ital, its readers, what we do well and what we don’t, and our future directions. indeed, we’re still digesting and discussing them, nearly a year after the survey. i’d like to use some of my editorial space in this issue to introduce, provide an overview, and highlight a few of the most interesting results. i strongly encourage you to access the full survey results, which i’ve posted to our weblog italica (http:// ital-ica.blogspot.com/); i further invite you to post your own thoughts there about the survey results and their meaning. we ran the survey from mid-december to mid-january. a few responses trickled in as late as mid-february. the survey invitation was sent to the 2,614 lita personal members; nonmembers and ital subscribers (most of whom are institutions) were excluded. we ultimately received 320 responses—including two from individuals who confessed that they were not actually lita members—for a response rate of 12.24 percent. thus the findings reported below reflect the views of those who chose to respond to the survey. the response rate, while not optimal, is not far from the 15 percent that i understand lita usually expects for its surveys. as you may guess, not all respondents answered all questions, which accounts for some small discrepancies in the numbers reported. who are we? in analyzing the survey responses, one of the first things one notices is the range and diversity of ital’s reader base, and by extension, of lita’s membership. the largest groups of subscribers identify themselves either as traditional systems librarians (58, or 18.2 percent) or web services/development librarians (31, or 9.7 percent), with a further cohort of 7.2 percent (23) composed of those working with electronic resources or digital projects. but more than 20 percent (71) come from the ranks of library directors and associate directors. nearly 15 percent (47) identify their focus as being in the areas of reference, cataloguing, acquisitions, or collection development. see figure 1. the bottom line is that more than a third of our readers are coming from areas outside of library it. a couple of other demographic items: ■■ while nearly six in ten respondents (182, or 57.6 percent) work in academic libraries, that still leaves a sizable number (134, or 42.3 percent) who don’t. more than 14 percent (45) of the total 316 respondents come from the public library sector. ■■ nearly half (152, or 48.3 percent) of our readers indicated that they have been with lita for five years or fewer. note that this does not necessarily indicate the age or number of years of service of the respondents, but it’s probably a rough indicator. still, i confess that this was something of a surprise to me, as i expected larger numbers of long-time members. and how do the numbers shake out for us old geezers? the 6–10 and greater-than-15-years cohorts each composed about 20 percent of those responding; interestingly, only 11.4 percent (36) answered that they’d been lita members for between 11 and 15 years. assuming that these numbers are an accurate reflection of lita’s membership, i can’t help but wonder about the explanation for this anomaly.” see figure 2. how are we doing? question 4 on the survey asked readers to respond to several statements: “it is important to me that articles in ital are peerreviewed.” more than 75 percent (241, or 77.2 percent) answered that they either “agreed” or “strongly agreed.” “ital is timely.” more than seven in ten respondents (228, or 73.0 percent) either “agreed” or “strongly agreed” that ital is timely. only 27 (8.7 percent) disagreed. as a technology-focused journal, where time-to-publication is always a sensitive issue, i expected more dissatisfaction on this question (and no, that doesn’t mean that i don’t worry about the nine percent who believe we’re too slow out of the gate). marc truitt editorial: the space in between, or, why ital matters marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 164 information technology and libraries | december 2010 would likely quit lita, with narrative explanations that clearly underscore the belief that ital—especially a paper ital—is viewed by many as an important benefit of membership. the following comments are typical: ■■ “lita membership would carry no benefits for me.” ■■ “dues should decrease, though.” [from a respondent who indicated he or she would retain lita “i use information from ital in my work and/ or i find it intellectually stimulating.” by a nearly identical margin to that regarding timeliness, ital readers (226, or 72.7 percent) either “agreed” or “strongly agreed” that they use ital in their work or find its contents stimulating. “ital is an important benefit of lita membership.” an overwhelming majority (248, or 79.78 percent) of respondents either “agreed” or “strongly agreed” with this statement.1 this perception clearly emerges again in responses to the questions about whether readers would drop their lita membership if we produced an electronic-only or open-access ital (see below). where should we be going? several questions sought your input about different options for ital as we move forward. question 7, for example, asked you to rank how frequently you access ital content via several channels, with the choices being “print copy received via membership,” “print copy received by your institution/library,” “electronic copy from the ital website,” or “electronic copy accessed via an aggregator service to which your institution/library subscribes (e.g., ebsco).” the choice most frequently accessed was the print copy received via membership, at 81.1 percent (228). question 8 asked about your preferences in terms of ital’s publication model. of the 307 responses, 60.6 percent (186) indicated a preference for continuance of the present arrangement, whereby we publish both paper and electronic versions simultaneously. four in ten respondents preferred that ital move to publication in electronic version only.2 of those who favored continued availability of paper, the great majority (159, or 83.2 percent) indicated in question 9 that they simply preferred reading ital in paper. those who advocate moving to electronic-only do so for more mixed reasons (question 10), the most popular being cost-effectiveness, timeliness, and the environmental friendliness of electronic publication. a final question in this section asked that you respond to the statement “if ital were to become an electronic-only publication i would continue as a dues-paying member of lita.” while a reassuring 89.8 percent (273) of you answered in the affirmative, 9.5 percent (29) indicated that

blogger who fends off bouts of insomnia by reading “wonky” ital papers in the wee hours of the morning. and that ain’t the half of it, as they say. in short—in terms of readers, interests, and preferences—“the space in between” is a pretty big niche for ital to serve. we celebrate it. and we’ll keep trying our best to serve it well. ■■ departures as i write these lines in late-september, it’s been a sad few weeks for those of us in the ital family. in mid-august, former ital editor jim kopp passed away following a battle with cancer. last week, dan marmion—jim’s successor as editor (1999–2004)—and a dear friend to many of us on the current ital editorial board—also left us, the victim of a malignant brain tumor. i never met jim, but lita president karen starr eulogized him in a posting to lita-l on august 16, 2010.3 i noted dan’s retirement due to illness in this space in march.4 i first met dan in the spring of 2000, when he arrived at notre dame as the new associate director for information systems and digital access (i think the position was differently titled then) and, incidentally, my new boss. dan arrived only six weeks after my own start there. things at notre dame were unsettled at the time: the libraries had only the year before successfully implemented exlibris’ aleph500 ils, the first north american site to do so. while exlibris moved on to implementations at mcgill and the university of iowa, we at notre dame struggled with the challenges of supporting and upgrading a system then new to the north american market. it was not always easy or smooth, but throughout, dan always maintained an unflappable and collegial manner with exlibris staff and a quiet but supportive demeanor toward those of us who worked for him. i wish i could say that i understood and appreciated this better at the time, but i can’t. i still had some growing ahead of me—i’m sure that i still do. dan was there for me again as an enthusiastic reference when i moved on, first to the university of houston in 2003 and then to the university of alberta three years later. in these jobs i’d like to think i’ve come to understand a bit better the complex challenges faced by senior managers in large research libraries; in the process, i know i’ve come to appreciate dan’s quiet, knowledgeable, and hands-off style with department managers. it is one i’ve tried (not always successfully) to cultivate. while i was still at notre dame, dan invited me to join the editorial board of information technology and libraries, a group which over the years has come to include many “friends of dan,” including judith carter (quite possibly the world’s finest managing editor), andy boze (ital’s membership] ■■ “ital is the major benefit to me as we don’t have funds for me to attend lita meetings or training sessions.” ■■ “the paper journal is really the only membership benefit i use regularly.” ■■ “actually my answer is more, ‘i don’t know.’ i really question the value of my lita membership. ital is at least some tangible benefit i receive. quite honestly, i don’t know that there really are other benefits of lita membership.” question 12 asked about whether ital should continue with its current delayed open-access model (i.e., the latest two issues embargoed for non-lita members), or go completely open-access. by a three-to-two margin, readers favored moving to an open-access model for all issues. in the following question that asked whether respondents would continue or terminate lita membership were ital to move to a completely open-access publication model, the results were remarkably similar to those for the question linking print availability to lita membership, with the narrative comments again suggesting much the same underlying reasoning. in sum, the results suggest to me more satisfaction with ital than i might have anticipated; at the same time, i’ve only scratched the surface in my comments here. the narrative answers in particular—which i have touched on in only the most cursory fashion—have many things to say about ital’s “place,” suggestions for future articles, and a host of other worthy ideas. there is as well the whole area of crosstabbing: some of the questions, when analyzed with reference to the demographic answers in the beginning of the survey, may highlight entirely new aspects of the data. who, for instance, favors continuance of a paper ital, and who prefers electronic-only? but to come back to that reader’s comment about ital and “the space in between” that i used to frame this discussion (indeed, this entire column): to me, the demographic responses—which clearly show ital has a substantial readership outside of library it—suggest that that “space in between” is precisely where ital should be. we may or may not occupy that space “awkwardly,” and there is always room for improvement, although i hope we do better than “flop around”! the results make clear that ital’s readers—who would be you!—encompass the spectrum from the tech-savvy early-career reader of code4lib journal (electronic-only, of course!) to the library administrator who satisfies her need for technology information by taking her paper copy of ital along when traveling. elsewhere on that continuum, there are reference librarians and catalogers wondering what’s new in library technology, and a traditional systems librarian pondering whether there is an open-source discovery solution out there that might breathe some new life into 166 information technology and libraries | december 2010 between membership and receiving the journal. many of them appear to infer that a portion of their lita dues, then, are earmarked for the publication and mailing of ital. sadly, this is not the case. in years past, ital’s income from advertising paid the bills and even generated additional revenue for lita coffers. today, the shoe is on the other foot because of declining advertising revenue, but ital is still expected to pay its own way, which it has failed to do in recent years. but to those who reasonably believe that some portion of their dues is dedicated to the support of ital, well, t’ain’t so. bothered by this? complain to the lita board. 2. as a point of comparison, consider the following results from the 2000 ital reader survey. respondents were asked to rank several publishing options on a scale of 1 to 3 (with 1 = most preferred option and 3 = least preferred option): ital should be published simultaneously as a print-onpaper journal and an electronic journal (n = 284): 1 = 169 (59.5%); 2 = 93 (32.7%); 3 = 22 (7.7%) ital should be published in an electronic form only (n = 293): 1 = 55 (18.8%); 2 = 61 (20.8%); 3 = 177 (60.4%) in other words, then as now, about 60% of readers preferred paper and electronic to electronic-only. 3. karen starr, “fw: [libs-or] jim kopp: celebration of life,” online posting, aug. 16, 2010, lita-l, http://lists.ala.

these extremely capable and dedicated folks. my fondest memories of dan concern our shared passion for model trains. i remember visiting a train show in south bend with him a couple of times, and our last time together (at the ala midwinter meeting in denver two years ago) was capped by a snowy trek with exlibris’ carl grant, another model train enthusiast, to the mecca of model railroading, caboose hobbies. three boys off to see their toys—oh, exquisite bliss! i don’t know whether ital or its predecessor jola have ever reprinted an editorial, but while searching the archives to find something that would honor both jim and dan, i found a piece that i hope speaks eloquently of their contributions and to ital’s reason for being. dan’s editorial, “why is ital important?” originally published in our june 2002 issue, appears again immediately following this column. i think its message and the views expressed therein by jim and dan remain as valid today as they were in 2002. they also may help to frame my comments concerning our reader survey in the previous section. farewell, jim and dan. you will both be sorely missed. notes and references 1. a number of narrative answers to the survey make it clear that ital readers who are lita members perceive a link 71 who will steer the ship? during 1973, the existence of two study groups sponsored by the council on library resources became informally known in the library automation community. by the time of the 197 4 ala midwinter meeting, the lack of formal identification of these groups, their goals, and their relation to clr provoked some spontaneous and possibly faulty responses from the ala members present. in the march 1974 issue of lola, ms. ruth tighe analyzed with perception and accuracy the behavior of information scientists attending that meeting. however, we feel that further attention should be paid to the precise situation in which we find ourselves. the council on library resources has, for eighteen months, funded a small group with the acronym of cembi. informal communication had it that this group of library automation experts originally was to devise a standardized subset of the marc monograph format; however, a full year passed without public announcement of this work. unable to come to an agreement, the group seems to have turned to specific strategies for interchange of machine-readable bibliographic data. these goals are, of course, valid and worthy of pursuit. clr also announced at midwinter the intent to administer a system plan for large-scale serials conversion to create a national serials data base. this project draws upon the considerable efforts of the ad hoc "toronto" group, which provided a status report of its efforts in the december 1973 issue of lola. in addition, an invitational conference was sponsored in april 197 4 by clr, to discuss national bibliographic control, with a small number of conference attendees and with a total absence of publicity. there are three major problems inherent in the situation described above, affecting not only the library automation community but libraries as a whole. first, there is no apparent justification for the air of secrecy which has surrounded clr' s direction of these worthy efforts. surely it must be abundantly clear to all administrators these days that in order to implement a far-reaching program it is necessary to inform if not consult with the target population. those librarians who are not associated with clr do not necessarily have axes to grind or home-grown systems to foist upon the world. they do wish to be kept informed of discussion and developments which may eventually have a direct effect upon their work. while it is perfectly reasonable to foster technical progress in a difficult area of study by forming a closed working group of skilled professionals, there seems to be little gained by avoiding recognition of such a group. 72 journal of library automation vol. 7/2 june 1974 second, the approach of these projects has sidestepped all the existing channels of operation and communication which we have been striving for over a decade to create. should clr wish a certain task perfornied, it should be able to contract with the library of congress or to fund an existing ala committee to carry out the work under the present circumstances, these established channels are likely to find their deliberations bypassed and superseded by these ad hoc groups. third, it seems important when determining issues (ad hoc standards for local input of marc-like monograph and serials records) which are of longrange concern to many libraries, that it is particularly important not to bias a development effort toward the needs of one type of library. the approach of the large research library, while important:'is not the only vantage point from which to perceive the problems of nationwide bibliographic systems. we recommend that the council on library resources find an alternate method of accomplishing its goals-a method which includes provision for adequate communication and which takes advantage of existing channels. such a method, for the cembi group, might be to declare its deliberations to be a user-group standards proposal for submission to the rtsd/isad/ rasd representation in machine-readable form of bibliographic information committee ( marbi), the appropriate ala committee. if clr wishes more intensive review of this or any other proposal from marbi, it could fund the necessary expenses for more frequent meetings of marbi. an analogous method would establish the serials project as a funded program, with the desired task goals, within the library of congress, the national serials data program, or an appropriate library union serials organization. clr has done many good deeds for the library world in its lifetime; it would indeed be unfortunate were it to inadvertently allow the growth of professional confusion and resentment that were evident at the midwinter meeting. susan k. martin modeling a library website redesign process: developing a user-centered website through usability testing danielle a. becker and lauren yannotta information technology and libraries | march 2013 6 abstract this article presents a model for creating a strong, user-centered web presence by pairing usability testing and the design process. four rounds of usability testing were conducted throughout the process of building a new academic library web site. participants were asked to perform tasks using a talk-aloud protocol. tasks were based on guiding principles of web usability that served as a framework for the new site. results from this study show that testing throughout the design process is an effective way to build a website that not only reflects user needs and preferences, but can be easily changed as new resources and technologies emerge. introduction in 2008 the hunter college libraries launched a two-year website redesign process driven by iterative usability testing. the goals of the redesign were to: • update the design to position the library as a technology leader on campus; • streamline the architecture and navigation; • simplify the language used to describe resources, tools, and services; and • develop a mechanism to quickly incorporate new and emerging tools and technologies. based on the perceived weaknesses of the old site, the libraries’ web committee developed guiding principles that provided a framework for the development of the new site. the guiding principles endorsed solid information architecture, clear navigation systems, strong visual appeal, understandable terminology, and user-centered design. this paper will review the literature on iterative usability testing, user-centered design, and thinkaloud protocol and the implications moving forward. it will also outline the methods used for this study and discuss the results. the model used, building the design based on the guiding principles and using the testing to uphold those principles, led to the development of a strong, user-centered site that can be easily changed or adapted to accommodate new resources and technologies. we believe this model is unique and can be replicated by other academic libraries undertaking a website redesign process. danielle a. becker (dbe0003@hunter.cuny.edu) is assistant professor/web librarian, lauren yannotta (lyannotta@hotmail.com) was assistant professor/instructional design librarian, hunter college libraries, new york, new york. mailto:dbe0003@hunter.cuny.edu mailto:lyannotta@hotmail.com modeling a library website redesign process | becker 7 background the goals of the research were to (1) determine the effectiveness of the hunter college libraries website, (2) discover how iterative usability testing resulting in a complete redesign impacts how the students perceive the usability of a college library website, and (3) reveal student informationseeking habits. a formal usability test was conducted both on the existing hunter college libraries website (appendix a) and the following drafts of the redesign (appendix b) with twenty users over an eighteen-month period. the testing occurred before the website redesign began, while the website was under construction, and after the site was launched. the participants were selected through convenience sampling and informed that participation was confidential. the intent of the usability test was to uncover the flaws in navigation and terminology of the current website and, as the redesign process progressed, to incorporate the users’ feedback into the new website’s design to closely match their wants and needs. the redesign of the website began with a complete inventory of the existing webpages. an analysis was done of the website that identified key information, links, units within the department, and placement of information in the information architecture of the website. we identified six core goals that we felt were the most important for all users of the library’s website: 1. user should be able to locate high-level information within three clicks. 2. eliminate library jargon from navigational system using concise language. 3. improve readability of site. 4. design a visually appealing site. 5. create a site that was easily changeable and expandable. 6. market the libraries’ services and resources through the site. literature review in 2010, oclc compiled a report, “the digital information seeker,” that found 84 percent of users begin their information searches with search engines, while only 1 percent began on a library website. search engines are preferred because of speed, ease of use, convenience, and availability.1 similar studies such as emde et al., and gross and sheridan, have shown that students are not using library websites to do their research.2 gross and sheridan assert in their article on undergraduate search behavior that “although students are provided with library skills sessions, many of them still struggle with the complex interfaces and myriad of choices the library website provides.” 3 this research shows the importance of creating streamlined websites that will information technology and libraries | march 2013 8 compete for our students’ attention. in building a new website at the hunter college libraries, we thought the best way to do this was through user-centered design. web designers both inside and outside the library have recognized the importance of usercentered design. nielsen advises that website structure should be driven by the tasks the users came to the site to perform.4 he asserts the amount of graphics on webpages should be minimized because they often affect page download times and that gratuitous graphics (including text rendered as images) should be eliminated altogether. 5 he also contends it is important to ensure that page designs are accessible to all users regardless of platform or newness of technology. 6 in their article, “how do i find an article? insights from a web usability study,” cockrell and jayne cited instances when researchers concluded that library terminology contributed to patrons’ difficulties when using library websites, thus highlighting the importance of understandable terminology. hulseberg and monson found in their investigation of student-driven taxonomy for library website design that “by developing our websites based on student-driven taxonomy for library website terminology, features, and organization, we can create sites that allow students to get down to the business of conducting research.” 7 performing usability testing is one way to confirm user-centered design. in his book don’t make me think!, krug insists that usability testing can provide designers with invaluable input. that, taken together with experience, professional judgment, and common sense, makes design choices easier.8 ipri, yunkin, and brown, in their article “usability as a method for assessing discovery,” emphasize the important role usability testing has in capturing emotional and aesthetic responses users have to websites, along with expressions of satisfaction with the layout and logic of the site. even the discovery of basic mistakes, such as incorrect or broken links and ineffective wording, can negatively affect discovery of library resources and services. 9 in battleson, booth, and weatherford’s literature review for their usability testing of an academic library website case study, they summarize dumas and redish's discussion of the five facets of formal usability testing: (1) the goal is to improve the usability of the interface, (2) testers should represent real users, (3) testers perform real tasks, (4) user behavior and commentary are observed and recorded, and (5) data are analyzed to recognize problems and suggest solutions. they conclude that when usability testing is "applied to website interfaces, this test method not only results in a more usable site, but also allows the site design team to function more efficiently, since it replaces opinion with user-centered design."10 this allows the designers to evaluate the results and identify problems with the design being tested. 11 usability experts nielsen and tahir contend that the earlier and more frequently usability tests are conducted, the more impact the results will have on the final design of the website because the results can be incorporated throughout the design process. they conclude it is better to conduct frequent, smaller studies with a maximum of five users. they assert, “you will always have discovered so many blunders in the design that it will be better to go back to the drawing board modeling a library website redesign process | becker 9 and redesign the interface than to discover the same usability problems several more times with even more users.” 12 based on the strength of the literature, we decided to use iterative testing for our usability study. krug points out that testing is an iterative process because designers need to create, test, and fix based on test results, then test again.13 according to the united states department of health and human services report “research-based web design and usability guidelines,” conducting before and after studies when revising a website will help designers determine if changes actually made a difference in the usability of the site.14 manzari and trinidad-christensen found in their evaluation of user-centered design for a library website, iterative testing is when a product is tested several times during development, allowing users’ needs to be incorporated into the design. in their study, their aim was that the final draft of their website would closely match the users’ information needs while remaining consistent, easy to learn, and efficient.15 battleson, booth, and weintrop report that there is “a consensus in the literature that usability testing be an iterative process, preferably one built into a web site’s initial design.” 16 they explain that “site developers should test for usability, redesign, and test again—these steps create a cycle for maintaining, evaluating and continually improving a site.” 17 george used iterative testing in her redesign of the carnegie mellon university libraries website and concluded that it was “necessary to provide user-centered services via the web site.” 18 cobus, dent, and ondrusek used six students to usability test the “pilot study.” then eight students participated in the first round of testing; then librarians modified the prototype and tested fourteen students in the second and final round. after the second round of testing they used the results of this test to analyze the user recordings and deliver the findings and proposed “fixes” to the prototype pages to the web editor.19 mcmullen’s redesign of the roger williams university library website was able to “complete the usability-refinement cycle” twice before finalizing the website design.20 but continued refinements were needed, leading to another round of usability tests to identify and correct problem areas.21 bauer-graham, poe, and weatherford did a comparative study of a library websites’ usability via a survey and then redesigned the website after evaluating the survey’s results. they waited a semester, distributed another survey to determine the functionality of the current site. the survey had the participants view the previous design and the current design in a side-by-side comparison to determine how useful the changes made to the site were. 22 when testing participants, in the article “how do i find an article? insights from a web usability study,” cockrell and jayne suggest using a web interface to perform specified tasks while a tester observes, noting the choices made, where mistakes occur, and using a “think aloud” protocol. they found that modifying the website through an ongoing, iterative process of testing, refining, and retesting its component parts improves functionality. 23 in conducting our usability testing we used a think-aloud protocol to capture the participants’ actions. van den haak, de jong, and schellens define think-aloud protocol as relying on a method information technology and libraries | march 2013 10 that asks users to complete a set of tasks and to constantly verbalize their thoughts while working on the tasks. the usefulness of this method of testing lies in the fact that the data collected reflect the actual use of the thing being tested and not the participants’ judgments about its usability. instead, the test follows the individual’s thoughts during the execution of the tasks. 24 nielsen states that think-aloud protocol “may be the single most valuable usability engineering method. . . . one gets a very direct understanding of what parts of the [interface/user] dialog cause the most problems, because the thinking aloud method shows how users interpret each individual interface item.” 25 turnbow ‘s article “usability testing for web redesign: a ucla case study” states that using the “think-aloud protocol” provides crucial real-time feedback on potential problems in the design and organization of a website.26 cobus, dent, and ondrusek used the think-aloud protocol in their usability study. they encouraged participants to talk out loud as they answered the questions, audio taped their comments, and captured their on-screen navigation using camtasia.27 this information was used to successfully reorganize hunter college library’s website. method an interactive draft of hunter college libraries redesigned website was created before the usability study was conducted. in spring 2009, the authors created the protocol for the usability testing. a think-aloud protocol was agreed upon for testing both the old site and the drafts of the new site, including a series of post-test questions that would allow participants to share their demographic information and give subjective feedback on the drafts of the site. draft questions were written, and we conducted mock usability tests on each other. after several drafts we revised our questions and performed pilot tests on an mlis graduate student and two undergraduate student library assistants with little experience with the current website. we ascertained from these pilot tests that we needed to slightly revise the wording of several questions to make them more understandable to all users. we made the revisions and eliminated a question that was redundant. all recruitment materials and finalized questions were submitted to the institutional review board (irb) for review and went through the certification process. after receiving approval we secured a private room to conduct the study. participants were recruited using a variety of methods. signs were posted throughout the library, an e-mail was sent out to several hunter college distribution lists, and a tent sign was erected in the lobby of the library. participants were required to be students or faculty. participants were offered a $10.00 barnes & noble gift card as incentive. applicants were accepted on a rolling basis. twenty students participated in the web usability study (appendix c). no faculty responded to our requests for participation so a decision was made to focus this usability test on students rather than faculty because students comprise our core user base. another usability test will be conducted in the future that will focus on faculty to determine how their academic tasks differ from undergraduates when using the library modeling a library website redesign process | becker 11 website. the redesigned site is malleable, which makes revisions and future changes in the design a predicted outcome of future usability tests. tests were scheduled for thirty-minute intervals. we conducted four rounds of testing using five participants per round. the two researchers switched questioner and observer roles after each round of testing. each participant was asked to think aloud while they completed the tasks and navigated the website. both researchers took notes during the tests to ensure detailed and accurate data was collected. each participant was asked to review the irb forms detailing their involvement in the study, and they were asked to consent at that time. their consent was implied if they participated in the study after reading the form. the usability test consisted of fifteen task-oriented questions. the questions were identical when testing the old and new draft site. the first round tested only the old site, while the following three rounds tested only the new draft site. we tested both sites because we believed that comparing the two sites would reveal if the new site improved performance. the questions (appendix d) were not changed after they were initially finalized and remained the same throughout the entire four rounds of the usability study. participants were reminded at the onset of the test and throughout the process that the design and usability of the site(s) were being tested, not their searching abilities. the tests were scheduled for an hour each, allowing participants to take the tests without time restrictions or without being timed. as a result, the participants were encouraged to take as much time as they needed to answer the questions, but were also allowed to skip questions if they were unable to locate answers. initially the tests were recorded using camtasia software. this allowed us to record participants’ navigation trails through their mouse movements and clicks. but, after the first round of testing, we decided that observing and taking notes was appropriate documentation, and we stopped using the software. after the participants completed the tests we asked them user preference questions to get a sense of their user habits and their candid opinions of the new draft of the website. these questions were designed to elicit ideas for useful links to include on the website and also to gauge the visual appeal of the site. information technology and libraries | march 2013 12 results table 1. percent of tasks answered correctly discussion hunter college libraries’ website was due for a redesign because the site was dated in its appearance and did not allow new content to be added quickly and easily. as a result, a decision was made to build a new site using a content management system (cms) to make the site easily expandable and simple to update. this study tested the simple tasks to determine how to structure the information architecture and to reinforce the guiding principles of the redesigned website. task successes and failures the high percentage of success of participants finding books on the redesigned website using the online library catalog and easily find library hours reinforced our guiding principle of understandable terminology and clear navigational systems. krug contends that navigation educates the user on the site’s contents through its visible hierarchy. the result is a site that guides the user through their options and instills confidence in task old site new site find a book using online library catalog 80% 86% find library hours 100% 100% get help from a librarian using questionpoint 40% 93% find a journal article 20% 66% find reference materials 0% 7% find journals by title 40% 66% find circulation policies 60% 53% find books on reserve 80% 73% find magazines by title 0% 73% find the library staff contact information 60% 100% find contact information for the branch libraries 40% 100% modeling a library website redesign process | becker 13 the website and its designers.28 we found this to be true in the way our users easily found the hours and catalog links on the prototype of our library website. the users on the old site knew where to look for this information because they were accustomed to how to navigate the old site. given that the prototype was a complete departure from the navigation and design of the old site, it was crucial that the labels and links were clear and understandable in the prototype or our design would fail. we made “hours” the first link under the “about” heading and “cuny+/books” the first link under the “find” heading and as a result both our terminology and our structure was a success with participants. on the old website, users rarely used the libraries’ online chat client. despite our efforts to remind students of its usefulness, the website didn’t sufficiently place the link in a reasonably visible location on the home page. in the old site, only 40 percent of participants located the link as it was on the bottom left of the screen and easy to overlook. instead, on the new site, the “ask a librarian” link was prominently featured on the top of the screen. these results upheld the guiding principles of solid information architecture and understandable terminology. it also supported nielsen’s assertion that “site design must be aimed at simplicity above all else, with as few distractions as possible and with a very clear information architecture and matching navigation tools.” 29 as a result the launch of the redesigned site, the use of the questionpoint chat client has more than doubled. finding a journal article on a topic was always problematic for users of the old library website. the participants we tested were familiar with the site, and 80 percent erroneously clicked on “journal title list” when the more appropriate link would have been “databases” if they didn’t have an exact journal title in mind. although we taught this in our information literacy courses, it was challenging getting the information across. in order to address this on the new site, “databases” was changed to “databases/articles” and categorized under the heading “find.” the participants using the new site had greater success with the new terminology; 66 percent correctly chose “databases/articles.” this question revealed an inconsistency with the guiding principals of understandable terminology and clear navigation systems on the old site. these issues were addressed by adding the word “articles” after “databases” on the new site to clarify what resources could be found in a database and also by placing the link under the heading “find” to further explain the action a student would be taking by clicking on the “databases/articles” link. finding reference materials was challenging for the users of the old site as none of the participants clicked on the intended link “subject guides.” in an effort to increase usage of the research guides, the library not only purchased the libguides tool, but also changed the wording of the link to “topic guides.” as we neared the end of our study we observed that only one participant knew to click on the “topic guides” link for research assistance. the participants suggested calling it “research guides” instead of “topic guides” and we changed it. unfortunately, the usability study was completed and we were unable to further test the effectiveness of the rewording of this link. anecdotally, the rewording of this link appears to be more understandable to users as the information technology and libraries | march 2013 14 research guides are getting more usage (based on hit counts) than the previous guides. the rewording of these guides adhered to both principles of understandable terminology and usercentered design. these results supported nielsen’s assertion that the most important material should be presented up front, using the inverted pyramid principal. “users should be able to tell in a glance what the page is about and what it can do for them.” 30 our results also supported the hhs report, which states that terminology “plays a large role in the user’s ability to find and understand information. many terms are familiar to designers and content writers, but not to users.” 31 we concluded that rewriting the link based on student feedback reduces the use of terminology. although librarians are “subject specialists” and “subject liaisons” and are familiar with those labels and that terminology, our students were looking for the word “research” instead of “subject” so they were not connecting with the library’s libguides. as previously discussed, students of the old site thought the link “journal title list” would give them access to the library’s database holdings. when asked to find a specific journal title the correct answer to this question on the old site was “journal title list,” with only 40 percent of the participants answering correctly. another change to terminology in the new site, both were placed under the heading “find,” and, after testing of the first prototype, “journal title list” was changed to “list of journals and magazines.” in the following tests 66 percent of the participants were able to answer correctly. the percentages of success in finding circulation policies between the old site and the prototype site were slight, only a 7 percent difference. this can be attributed to the fact that participants on the old site could click on multiple links to get to the correct page, and they were familiar enough with the site to know that. in the prototype of the site there were several paths as well, some direct, some indirect. testing the wording of this link supported the understandable terminology principle, more so than the old website’s “library policies” link, yet to be true to our user-centered design principle, we needed to reword it once more. therefore, after the test was completed and the website was launched, we reworded the link to “checkout policies,” which utilizes the same terminology that users are familiar with because they checkout books at our checkout desk. the remaining tasks consisted of locating information, such as finding books on reserve, magazines by title, library staff contact information, and finding branch information were all met with higher success rates in the prototype site because in the redesign process the links were reworded to support the understandable terminology and user-centered design principles. participant feedback: qualitative the usability testing process informed the redesign of our website in many specific ways. if the layout of the site didn’t test well with participants, we planned to create another prototype. in their evaluation of colorado state universities libraries’ digital collections and the western waters digital library websites, zimmerman and paschal describe the importance of first impressions of a website as the determining factor of whether users return to a website; if it is positive they will return and continue to explore.32 modeling a library website redesign process | becker 15 when given an opportunity to give feedback on what they thought of the design of the website the participants commented: • “there were no good library links at the bottom before and there wasn’t the ask a librarian link either which i like a lot.” • “the old site was too difficult to navigate, new site has a lot of information, i like the different color schemes for the different things.” • “it is contemporary and has everything i need in front of me.” • “cool.” • “helpful.” • “straightforward.” • “the organization is easier for when you want to find things.” • “interactivity and rollovers make it easy to use.” • “intuitive, straight-forward and i like the simplicity of the colors.” • “more professional, more aesthetically pleasing than the old site.” • “the four menu options (about, find, services, help) break the information down easily.” additional research conducted by nathan, yeow, and murguesan claims attractiveness (referring to aesthetic appeal of a website) is the most important factor in influencing customer decisionmaking and affects the usability of the website.33 not only that, but users feel better when using a more attractive product. fortunately, the feedback from our participants revealed that the website was visually appealing, and the navigation scheme was clear and easy to understand. other changes made to the libraries’ website because of usability testing participants commented that they expected to find library contact information on the bottom of the homepage, so the bottom of the screen was modified to include this information as well as a “contact us” link. participants did not realize that the “about,” “find,” “services,” and “help” headings were also links, so we modified them so they were underlined when hovered over. there were also adjustments to the gray color bars on the top of the page because participants thought they were too bright, so they were darkened to make the labels easier to read. participants also commented that they wanted links to various public libraries in new york city under the “quick links” section of the homepage. we designed buttons for brooklyn public library, queens public library, and the new york public library and reordered this list to move these links closer to the top of the “quick links” section. information technology and libraries | march 2013 16 conclusion conducting a usability study of hunter college libraries existing website and the various stages of the redesigned website prototypes was instrumental in developing a user-centered design. approaching the website redesign in stages, with guidance from iterative user testing and influenced by the participants’ comments, gave the web librarian and the web committee an opportunity to incorporate the findings of the usability study into the design of the new website. rather than basing design decisions on assumptions of users’ needs and information seeking behaviors, we were able to incorporate what we’d learned from the library literature and the users’ behavior into our evolving designs. this strategy resulted in a redesigned website that, with continued testing, user feedback, and updating, has aligned with the guiding principles we developed at the onset of the redesign project. the one unexpected outcome from this study is that we discovered that despite how well a library website is designed, users will still need to be educated in how to use the site with an emphasis on developing strong information literacy skills. references 1. “the digital

and the ital editorial board, is senior it & facilities officer, learning services, university of alberta. what a pleasure it has been to scan through a decade of articles, communications, and news from the ten volumes comprising the 1970s’ journal of library automation, predecessor to information technology and libraries. despite the open-access availability of several of these volumes, i requested the entire run from our high density storage library and delighted in the dusty covers between my hands and the musty smells wafting from the paper and ink. at the same time, i rued past practices at this university library of slicing out journal covers and front and back advertising in order to save a few cents in bindery costs. such a loss of information about a journal’s history! by the end of the 1970s, i was almost through my undergraduate degree and intended to pursue a library science degree after a gap year, not being able to imagine a more inspiring or satisfying place to build a career than an academic library. even as an avid library user at that time, i realized that technology was having an increasing impact on operations but, until reviewing these ten years of the journal, did not grasp the tipping point reached. the decade began with tentative language around technology including uncertainty about whether this phenomenon was best called mechanization or automation. that uncertainty extended to the naming of new things, resulting in words not yet joined, or if joined, then with hyphenation: data base or data-base, key word or key-word, on line or on-line, for example. in the early years, the profession began to imagine the coming together of disparate small library applications into what was referred to as a “total” system; the integrated library system or ils had neither been imagined nor articulated. early concerns in the decade focused on the rising costs of library services alongside the high price of computing. cost-benefit analysis drove many decisions related to library automation. in a 1970 article conceptualizing an online catalog, frederick kilgour claimed that the “productivity of library workers is not continuously increasing as is that of workers in the general economy”1 and concluded that “mechanization, or more specifically, computerization, is the only avenue that extends toward the goal of economic viability.”2 fortunately, the decade saw considerable advances in computer engineering coinciding with steadily decreasing costs in processing power, data storage and networking. nine year later, computer scientist g. salton imagined a much more viable future for libraries, “postulating a completely new library design where the shelf arrangement of books and journals would be replaced by a computerized store containing presumably the full text of all library items together with appropriate search methodologies.”3 while several decades would pass before the emergence of project gutenberg and other mass book scanning projects, technology was sufficiently affordable for libraries by the end of the 1970s that the focus shifted to ways of working cooperatively to harness the powerful new opportunities. jola attracted articles on library networks, cataloguing cooperatives, union serial lists, robust circulation systems, early interlibrary loan systems, and commercial and not-for-profit database services. many applications and systems grew out of projects begun at university and other libraries, but the decade also saw the early emergence of vendor solutions. by the final volume of the 1970s, caryl and stratton mcallister reported on mailto:sandra.shores@ualberta.ca the 1970s in review | shores 8 https://doi.org/10.6017/ital.v37i2.10494 dobi/libis, “an integrated library system with strong authority file control that can be used directly by the library staff and its borrowers.”4 the ils was born. a few professional themes that still resonate today stand out from this glance into the past, the first being a shift from valuing ownership of materials to valuing cooperation and resource sharing. technology combined with an increasing emphasis on standards of description and communication offered new possibilities for regional and national resource sharing, leading many in the profession to acknowledge the futility of trying to build comprehensive collections for their institutions. a number of articles highlight the impact of technology on library personnel, noting that the introduction of automation is disruptive to staff, leaving many feeling unprepared to succeed in their jobs. the roots of evidence-based decision making can be seen in a few articles, for example one describing how newly available data from first generation circulation systems can inform the acquisition of additional copies of high demand titles. 5 the library user comes more into focus as the decade progresses, in studies about user satisfaction with mediated search and retrieval services, whether run in batch mode or online, and in concept papers imagining systems that support end-user searching. other articles express concern over the costs of online searching and other computer services, especially as the costs of library materials continued to rise and journals consumed more of the collections budget. finally, members of the profession understood early that data about use of library materials stored in computer systems needs protection. at the ala midwinter meeting in 1973, the information science and automation division (precursor to lita) passed a motion urging ala to develop data privacy policy, noting the “vulnerability of machine-readable files due to the large quantity of data processed.”6 william mathews provides an excellent article to read in anticipation of library technologies in the 1980s. with considerable prescience in “advances in electronic technologies” he takes the reader through microprocessors, high performance computing, the pending home computer phenomenon and new storage and processing technologies.7 by the end of the 1970s, the library world was on the cusp of a technology revolution! in bringing this review to a close, i would be remiss not to draw attention to the illustrious professionals who assumed editorial roles in the early years of the journal. frederick kilgour, henriette avram, verner clapp, pauline atherton, and others not only had extraordinary careers but also set high standards for the journal and the association. kudos to them for their establishment of jola! 1

of it services for kansas state university libraries. jason coleman (coleman@ksu.edu) is head of library user services for kansas state university libraries. abstract as with any shared format for serializing data, primo’s pnx records have limits on the types of data which they pass along from the source records and into the primo tool. as a result of these limitations, pnx records do not currently have a provision for harvesting and transferring rights information about hathitrust holdings that the kansas state university (ksu) library system indexes through primo. this created a problem, since primo was defaulting to indicate that all hathitrust materials were available to ksu libraries (k-state libraries) patrons, when only a limited portion of them actually were. this disconnect was infuriating some library users, and creating difficulties for the public services librarians. there was a library-wide discussion about removing hathitrust holdings from primo altogether, but it was decided that such a solution was an overreaction. as a consequence, the library it department began a crash program to attempt to find a solution to the problem. the result was an application called hathigenius. introduction many information professionals will be aware of primo, the web scale discovery tool provided by ex libris. web scale discovery services are designed to provide indexing and searching user experiences, not only for the library’s holdings (as with a traditional online public access catalog), but also for many of a library’s licensed and open access holdings. primo offers a variety of useful features for search and discovery, taking in data from manifold sources and serializing them into a common format for indexing within the tool. however, such applications are still relatively young, and the technologies powering them have not fully matured. the combination of this lack of maturity and deliberately closed architecture between vendors leads to several problems for the user. one of the most frustrating is errors in identifying full-text access availability. as with any shared format for serializing data, primo’s pnx (primo normalized xml) records have limits on the types of data they pass from the source records into the primo tool. as a result of these limitations, pnx records do not currently have a provision for harvesting and transferring rights information about hathitrust holdings that the k-state libraries system indexes through primo. this created a problem in the k-state libraries’ implementation, since primo was defaulting to indicate that all hathitrust materials were available to k-state libraries patrons, when only a limited portion of them actually were. this disconnect was infuriating some library users, and creating difficulties for the public services librarians. there was a library-wide discussion about removing hathitrust holdings from primo altogether, but it was decided that such a solution was an overreaction. as a consequence, the library it services department began a crash program to attempt to find a solution to the problem. taking the long way around | bengston and coleman 28 https://doi.org/10.6017/ital.v38i1.10574 hathitrust’s digital library as a collection in primo central hathitrust was established in 2008 as a collaboration among several research libraries that were interested in preserving digital content. as of the beginning of march 2018, the collaborative’s digital library contained more than sixteen million items, approximately 37 percent of which were in the public domain.1 ex libris’ primo central index (pci), which serves as primo’s built-in index of articles from various database providers, includes metadata for the vast majority of the items in hathitrust’s digital library, providing inline frames within the original primo user interface to directly display full-text content of those items that the library has access to. libraries subscribing to primo choose whether or not to make these records available to their users. k-state libraries, like many other primo central clients, elected to activate hathitrust in its instance of primo, which it has branded with the name search it. the unmodified version of primo central identified all records from hathitrust’s digital library as available online, regardless of the actual level of access provided to users. users who discovered a record for an item from hathitrust’s digital library were presented with a conspicuous message indicating that full text was available and two links named view it and details. an example of the appearance of these search results is shown in figure 1. after clicking the “view it” tab, the center window would display the item’s homepage from hathitrust’s digital library inside an iframe. public domain items would display the title page of the item and present users with an interface containing numerous visual indicators that they were viewing an ebook (see figure 2 for an example). items with copyright restrictions would display a message indicating that the item is not available online (see figure 3 for an example). figure 1. two books from hathitrust as they appeared in search it prior to implementation of hathigenius. information technology and libraries | march 2019 29 figure 2. hathitrust result for an item in the public domain. figure 3. hathitrust’s homepage for an item that is not in the public domain. despite the intentions evident in the design of the primo interface, availability of hathitrust records was not being accurately reflected in the list of returns. the size of the indices underlying web scale discovery systems and the number of configurations and settings that must be maintained locally introduce a variety of failure points that can intercede when patrons attempt to access subscribed resources.2 one of the failure points identified by sunshine and carter is inaccurate knowledgebase information. the scope of inaccurate information about hathitrust items in primo central index constituted a particularly egregious example of this type of failure. patron reaction to misinformation about access to hathitrust between the time hathitrust’s digital library was activated in search it and the time the hathigenius application was installed at least thirty patrons contacted k-state libraries to ask why they were unable to access a book in hathitrust when search it had indicated that full text was available for the book. many of these expressed frustration at frequently encountering this error (for an example, see figure 4). taking the long way around | bengston and coleman 30 https://doi.org/10.6017/ital.v38i1.10574 1:08 26389957777759601093088133 i find it misleading that the search it function often finds a book i am interested in, but sometimes says it is available online; however, oftentimes it takes me to the hathi trust webpage for the book where i

items in hathitrust. staff reaction to misinformation about access to hathitrust reference staff at k-state libraries use a ticketing system to report electronic resource access problems to a team of librarians who troubleshoot the underlying issues. shortly after the hathitrust library was activated in search it, reference staff submitted several tickets about problems with access to items in that collection. members of the troubleshooting team responded quickly and informed the reporting librarians that the problem was one beyond their control. this message was slow to reach the entirety of the reference staff and was not always understood as being applicable to the full range of access problems our patrons were experiencing. samples and healy note that this type of decentralization and reactive orientation is common in electronic resource troubleshooting.3 like them, k-state libraries recognized a need to develop best practices to obviate confusion. we also found ourselves pining for a tool such as that described by collins and murray that could automatically verify access for a large set of links.4 the extent of displeasure with the situation was so severe that some librarians stated they were loath to promote search it to students since several million records were so conspicuously inaccurate. information technology and libraries | march 2019 31 technical challenges the k-state libraries it department wanted to fix the situation, in order to provide accurate expectations to their users, but doing so presented severe technical challenges, the most significant of which stemmed from the lack of rights information in the pnx record in primo. without more accurate information on availability, user satisfaction seemed destined to remain low. research into patron use of discovery layers predicted this unsurprising dissatisfaction. oclc’s (2009) research into what patrons want from discovery system led the researchers to conclude that “a seamless, easy flow from discovery through delivery is critical to end users. this point may seem obvious, but it is important to remember that for many end users, without the delivery of something he or she wants or needs, discovery alone is a waste of time.”5 a later usability study reported: “some participants spent considerable time looking around for features they hoped or presumed existed that would support their path toward task completion.”6 additionally, the perceived need to customize discovery layers so that they reflect the needs of a particular research library is hardly new, or exclusive to k-state libraries. the same issue was confronted by catalogers at east carolina university, as well as catalogers at unc chapel hill.7 nonetheless, the challenge posed by discovery layers comes with opportunity, as james madison university discovered when their ebsco discovery service widget netted almost twice the usage of their previous library catalog widget, and as the university of colorado discovered when they observed users attempting to use the discovery layer search box in “google-like” ways that could potentially aid discovery layer creators (as well as library it departments) in both design and in setting expectations.8 as previously noted, primo’s results display is driven by pnx records (see figure 5 for an example). the single most fundamental challenge was finding a way to get to holdings rights information despite that data not being present in the pnx records, or, consequently, the search results that showed up in the presentation layer. there was no immediate option to create a solution that leveraged “server-side” resources, where the data itself resided and was transformed, since k-state libraries subscribes to primo as a hosted service, and ex libris provided no direct server-side access to k-state libraries. some alternative way had to be found to locate the rights data for individual records and populate it into the primo interface. upon assessing the situation, the assistant director, it (ad) decided that one potential approach would be to independently query the hathitrust bibliographic application programming interface (api) for rights information. this approach solved a number of fundamental problems, but also posited its own questions and challenges: 1. some server-side component would still be needed for part of the query . . . where would that live and how could it be made to communicate with the javascript k-state libraries had injected into its primo instance? 2. how to best isolate hathitrust object identifiers from primo and then use them to launch an api query? 3. how to keep those responses appropriately “pinned” to their corresponding entries on the primo page? 4. how would the hathitrust bibliographic api perform under load from search it queries? answering these questions would require significant research into the hathitrust bibliographic api documentation, and extensive experimentation. taking the long way around | bengston and coleman 32 https://doi.org/10.6017/ital.v38i1.10574 figure 5. a portion of the pnx record for http://hdl.handle.net/2027/uc1.32106011231518 (the second item shown in figure 1). building the application of these four questions, the first was easily the most challenging: where would the server-side component live and how would it work? the k-state libraries it services department had, in the past, made a number of significant modifications to the appearance and functionality of the primo application by adding javascript to the static html tiles used in the primo interface. however, generally speaking, javascript cannot successfully request data from outside of the domain of the web document it occupies. requesting data from an api across domains requires the mediation of a server-side appliance. the ad constructed one for this purpose, using the php programming language. this script would serve as an intermediary between the javascript in primo and the hathitrust api. the appliance accepted data from the primo javascript in the form of the contents of http variables (encoded in the url of the get request to the php appliance), then used those values to query the hathitrust api. however, since this server-side appliance did not reside in the same domain as k-state libraries’ primo instance, the problem of getting the returned api data from the php appliance to the javascript still remained. this problem was solved by treating the php appliance as a javascript file for purposes of the application. while javascript cannot load data from another domain, a web document may load actual javascript files from anywhere on the web. the hathigenius appliance takes advantage of this fact by calling the php appliance programmatically as a javascript file, with a javascript object notation (json) version of the identifiers of any hathitrust entries encoded as part of the url used to call the file. the php script runs the queries against the api and returns a javascript file consisting of a single variable containing the json data encoding the availability information for the hathitrust entries as supplied from the bibliographic api . . . essentially appearing to the browser as a standard javascript file. information technology and libraries | march 2019 33 the second and third problems were intrinsically interrelated, and essentially boiled down to finding a unique identifier to use in an api query from the hathitrust entries. the most effective way to handle these queries was to use the “htid” identifier, which was largely unique to hathitrust entries, could be easily extracted from any entries that contained it, and would form the basis of the php script’s request to the hathitrust restful api to obtain rights information. in the process of harvesting the htid, hathigenius also copies the id for the object in the webpage that serves as the entry in the list of primo returns containing that htid. as the data is moved back and forth for processing, the htids, and later the resultant json data, remain paired to the object id for the entry in the list of returns. when hathigenius receives the results of the api query, it can then easily rewrite those entries to reflect the rights data it obtained. the fourth question has been fully answered with time. to this point, well over a year after hathigenius was activated in production, library it has not observed any failure of the api to deliver the requested results in testing, and no issues to that effect have been reported by users. log data indicates that, even under heavy load, the api is performing to expectations. further modifications originally, the hathigenius application supplied definitive states of available or unavailable for each entry. however, some experimentation showed this approach to be less than optimal. since the bibliographic api cannot be queried by kansas state university as a specific user, but rather was being queried for general access rights, the possibility still existed for false negatives in the future, if kansas state university’s level of access to hathitrust changed. the data returned from the api queries, when drilled down, just consisted of the usrightsstring property from the api, which corresponded to open-source availability, and did not account for any additional items available to the library by license in the future. after the application had been active for a short time, to mitigate this potential issue, the “not available” state (consisting of an application of the “exlresultstatusnotavailable” class to the hathitrust entry) was “softened” into an application of the “exlresultstatusmaybeavailable” class and verbiage asking users to check the “view it” tab for availability. a few weeks after deployment, it received a ticket indicating hathigenius was failing to work properly. the source of the problem proved to be detailed bibliographic pages for items in a search results list, which were linking out from the search entries. these pages used a different class and object structure than the search results pages in primo, requiring that an additional module be built into hathigenius to account for them. once the new module was added to the application and put into place, the problem was resolved. a second issue presented itself some weeks later, when a few false negatives were reported. at first, the assistant director assumed that licensing had changed, creating a disparity between the access information from the usrightsstring property and the library’s actual holdings. however, upon investigation it was clear that hathigenius was dropping some of the calls to the hathitrust bibliographic api. the api itself was performing as expected under load, however, and the failure proved to be coming from an unexpected source. the php script used by hathigenius to interface with the api was employing the curl module, which, in turn, was using its own, less secure certificate to establish a secure socket layer (ssl) connection to the hathitrust server. once the taking the long way around | bengston and coleman 34 https://doi.org/10.6017/ital.v38i1.10574 script was refactored to employ the simpler file_get_contents function, which relied upon the server’s main ssl certificate, the problem was fully resolved. hathigenius also had a limited vulnerability to bad actors. while the internal script’s destination hardwiring prevented hathigenius from being used as a generic tool to anonymously query apis, the library did encounter a situation in which a (probably inadvertently) malicious bot repeatedly pinged the script, causing it to use up system resources until it interrupted other services on the host machine. modifications were added to the script to provide a simple check against requests originating from primo. additionally, restrictions were placed on the script so that excessive resource use would cause it to be intermittently deactivated. while not perfect solutions, these measures have prevented a repeat of the earlier incident. k-state libraries has recently finished work on its version of the new primo user interface (primo new ui), which was moved into production this year. the new interface has a completely different client-side structure, requiring a very different approach to integrating hathigenius.9 appearance of hathitrust results in primo after hathigenius when the hathigenius api does not find a usrights property, we configured primo to display a yellow dot and the text “please check availability with the view it tab” (see figure 6 for an example). as noted earlier, we originally considered this preferable to displaying a red dot and the text “not available online,” because there might be instances in which the item is actually available in full view through hathitrust despite the absence of usrights in the record. figure 6. two books for which hathigenius found no usrights in hathitrust. when the hathigenuis api finds usrights, we configured primo to display a green dot and text “available online” (see figure 7 for an example). information technology and libraries | march 2019 35 figure 7. a book for which hathigenius found usrights. patron response since the beginning of 2017, the reference staff at k-state libraries have received no reports of patrons encountering situations in the original user interface in which primo indicates that full text is available but hathitrust is only providing a preview. however, a small number of patrons (at least four) expressed confusion at seeing a result in primo and discovering that the full-text is not available. some of those patrons noted that they saw the text “please check availability with the view it tab,” and inferred that this was meant to state that the full-text was available. others indicated that they never considered that we would include results for books that we do not own. these responses add to the body of literature documenting user expectations that everything should be available in full-text in an online library and that systems should be easy to use.10 internal response in order to gauge the feelings of k-state libraries’ staff who regularly assist patrons with reference questions, the authors crafted a brief survey (included in appendix a). respondents were asked to indicate whether they had noticed a positive change following implementation of hathigenius, a negative change, or no change at all. they were also invited to share comments. the survey was distributed to thirty individuals. twelve (40 percent) of those thirty responded to the survey. the survey response indicated a great deal of ambivalence by reference staff toward the change, with four individuals (33 percent) indicating they had not noticed a difference, and another four (33 percent) indicating that they had noticed a difference, but that it had not improved the quality of search results. only two (17 percent) of the respondents revealed that they had noticed an improvement in the quality of the search results. one (9 percent) respondent indicated that they felt that the hathitrust results had gotten noticeably worse since the introduction of hathigenius, although they did not elaborate on this in the survey question which invited further comment. the remaining respondent stated that they did not have an opinion. four comments were left by respondents, including one which indicated displeasure with the new, softer verbiage for hathitrust “negatives,” and one who claimed that the problem of false positives persisted, despite such feedback not being seen by the authors through any of the statistical modalities currently used for recording reference transactions. one user praised hathigenius, while another related broad displeasure with the decision to include hathitrust records in search it. that individual claimed that almost none of the results from hathitrust were available and stated that the hope engendered by the presence of the hathitrust results and the corresponding suggestion to check the view it tab was always dashed, to the detriment of patron satisfaction. taking the long way around | bengston and coleman 36 https://doi.org/10.6017/ital.v38i1.10574 the new ui as previously mentioned, in late 2018, k-state libraries adopted the primo new ui created by ex libris. this new user interface was built in angular, and changed many aspects about how hathigenius had to be integrated into primo. the k-state libraries’ it department completed a refactoring (reworking application code to change how an application works, but not what it does) of hathigenius to integrate it with the new ui and released it into production in september 2018. as an interesting aside, the it department did not initially prioritize the reintegration of hathigenius, due to the ambivalence of the response to the application evidenced by the survey conducted for this paper. however, shortly after search it was switched over to the new ui, complaints about the hathitrust results again displaying inaccurate availability information began to come in to the it department via both email and tickets from reference staff. as the stridence of the response increased, the project was reprioritized, and the work completed. future directions as previously mentioned, hathigenius currently uses the very rough “usrightsstring” property value from the hathitrust bibliographic api. however, the api also delivers much more granular rights data for digital objects. a future version of the app may inspect these more granular rights codes and compare them to rights data from k-state libraries in order to more definitively provide access determinations for hathitrust results in primo should the licensing of hathitrust holdings be changed. similarly, since htid technically only resolves to the volume level, a future version may additionally harvest the hathitrust record number, which appears to be extractable from the primo entries. based on feedback from the survey, the “soft negative” verbiage used in hathigenius was replaced with a firmer negative. this decision proved especially sagacious given that, once the early issues with certificates and communication with the hathitrust bibliographic api were sorted out, the accuracy of the tool seemed to be fully satisfactory. another problem with the “soft negative” was the fact that it asked users to click on the view-it tab, when many users simply chose to ignore the tabs and links in the search results, instead clicking on the article title, as found in a usability study on primo conducted by the university of houston libraries.11 it is also worth noting the one survey respondent who is apparently not seeing an improvement in hathitrust accuracy. if the continued difficulties they have indicated can be documented and replicated, the it department can examine those complaints to investigate where the tool may be failing. discussion one interesting feature of this experience is the seeming disconnect between library reference support staff and users in terms of the perception of the efficacy of the tool. this disconnect is all the more curious given the negative reaction displayed by reference support staff when hathigenius became unavailable temporarily upon introduction of the primo new ui. part of this perceived disconnect may be a result of the fact that staff were given a survey instrument, while the reactions of users have been determined largely via null results (a lack of complaints to, or information technology and libraries | march 2019 37 requests for assistance from, service point staff). however, given the dramatic drop in user complaints compared to the ambivalent reaction to the tool by most of the survey respondents, it appears that the staff had a much less enthusiastic response to the intervention than patrons. a few possibilities occur to the authors, including a general dislike for the discovery layer by reference librarians, a general disinclination toward a technological solution by some respondents, or the initial perception by at least part of the reference staff that the problem was not significant. as noted by fagan et al., the pivot toward discovery layers has not been a comfortable one for many librarians.12 until further research can be conducted on this, and reactions to similar customization interventions, these possibilities remain speculation. one particular feature of note with hathigenius is the use of what one of the authors refers to as “sidewise development” to solve problems that seem to be intractable within a proprietary, or open source, web-based tool. while not a new methodology in and of itself, the author has mainly encountered this type of design in ad-hoc creations, rather than as a systematic approach to problem-solving. instead of relying upon the capabilities of primo, this type of customization made its own query to a relevant api and blended that external data with the data available from primo seamlessly within the application’s presentation layer in order to facilitate a solution to a known problem. the solution created in this fashion was portable, and unaffected by most updates to primo itself. even the transition to the new ui required changes to the “hooks” and timing used by the javascript, rather than any substantial rewrite of the core engines of the application. this methodology has been used repeatedly by k-state libraries it services to solve problems where other interventions would have necessitated the creation of specialized modules, or the rewriting of source code; both of which would be substantially affected by updates to the product itself, and which would have been difficult to improve or version without down time to the affected product. similar solutions have seen tools independently query an application’s database in order to inject the data back into the application’s presentation layer, bypassing the core functionality of the application. conclusion reactions at this point from users, and at least some library staff, have been positive. while not a perfect tool, hathigenius has improved the user experience, removing a point of frustration and an area of disconnect between the library and its users. the application itself is fully replicable by other institutions (as is the general model of sideways development), allowing them to improve the utility of their primo instances. as with many possible customizations to discovery layers, hathigenius provides fertile ground for additional work, research, and refinement, as libraries struggle to find the most effective ways to implement discovery tools within their own environments. beyond hathigenius itself, the sideways development method provides a powerful tool for libraries to improve the tools they use by integrating additional functionality at the presentation layer level. tackling the problem of inaccurate full-text links in discovery layers is only one application of this approach, but it is an important one. as libraries continue to strive to improve the results and usability of their search offerings, the ability to add local customizations and improvements will be an essential feature for vendors to consider. taking the long way around | bengston and coleman 38 https://doi.org/10.6017/ital.v38i1.10574 appendix a. feedback survey q1 in january 2017, the library began

board. © 2020. we are now almost seven months into our new lives with the novel coronavirus and over 190,000 americans have died of covid-19. library administrators have been struggling with their commitment to provide services to their communities while keeping their staff safe. initially, libraries relied on their online offerings, so more e-books and other online resources were acquired. staff learned that they could do quite a bit of their work from home. they could still respond to email and phone messages. they could evaluate and order new material. they could deliver online programs like summer reading and story time. they could interact with people on social media. they could put together key resources for patrons and post them on the website.1 a lot of what the library was doing while the buildings were closed was not obvious. most people associate the library with the building and since the building was closed… it seemed like nothing was happening at the library. yet, library workers were busy. once it became possible for library staff to enter the building (per local health ordinances), the first thing that libraries started to do was accept returns. that was a little fraught considering how little we knew about the virus and how long contaminants might live on returned library material. eventually with the long-awaited testing results from the realm project and battelle labs (https://www.webjunction.org/explore-topics/covid-19-research-project.html), people started standardizing on a three-day quarantine of returns. then more testing of stacked material was done resulting in some people choosing to quarantine returns for four days. as of early september, we have learned that even five days isn’t enough to quarantine delivery totes and some other plastic material. curbside pick-up was born in these early days of being allowed back in the buildings. if someone had mapped who was offering curbside pick-up, it would look like popcorn popping across the country. the number of libraries offering the service slowly increased and pretty soon nearly everyone was doing it.2 many library directors will say that curbside pick-up is here to stay. people love the convenience too much to take the service away. rolling out curbside pick-up has had some challenges: how to safely make the handoff between library staff and library patrons; whether to accept returns; whether to charge fines; modifying mailto:lori.ayre@galecia.com https://www.webjunction.org/explore-topics/covid-19-research-project.html information technology and libraries september 2020 what more can we to do address broadband inequity and poverty? | ayre 2 circulation policies to fit the current needs; and selecting books for people that want them but who don’t have the skills needed to negotiate the library catalog’s requesting system. some libraries started putting together grab bags of materials selected by staff for specific patrons—kind of like homebound services on-the-fly. curbside helped get material in circulation again. importantly, also during this period, libraries started finding creative ways to get wi-fi hotspots out into communities. they began lending them if they weren’t already. those libraries already circulating hotspots increased their inventory. they took their bookmobiles into neighborhoods and created temporary hotspot connections around town. many libraries made sure wi-fi from their building was available in their own parking lots.3 but one thing everyone has learned during this pandemic is that libraries alone cannot be the solution to the digital divide. this isn’t news to librarians who have been arguing that internet access should be as readily available as electricity and water. librarians understand that information cannot be free and accessible unless everyone has internet access and knows how to use it. public access computers, wi-fi hotspots, and media literacy are all staple services in our libraries today.4 however, these services are not enough to bridge a digital divide that only seems to be getting worse. the coronavirus that closed libraries and schools has made it painfully clear that something much bigger has to happen to address the problem. as gina millsap stated in a recent facebook post: i think it’s become obvious that the covid-19 crisis is shining a spotlight on the flaws we have in our broadband infrastructure and on our failure to make the investments that should have been made for equitable access to what should be a basic utility, like water or electricity.5 according to broadbandnow, the number of people who lack broadband internet access could be as high as 42 million.6 the fcc reports that at least “18 million people lacked access to broadband internet at the end of 2018.”7 even if all the libraries were open and circulating hundreds of wi-fi hotspots, we’d still have a very serious access problem. thinking differently about addressing the digital divide in a paper published march 28, 2019, by the urban libraries council (ulc), the author suggested three specific actions that libraries can take to address race and social equity and the digital divide. they are: 1. assess and respond to the needs of your community through meaningful conversation (including considering different partners for your work) 2. optimize funding opportunities to support your efforts (e.g. e-rate), and information technology and libraries september 2020 what more can we to do address broadband inequity and poverty? | ayre 3 3. think outside the box to create effective solutions that are informed by those in need (e.g. lending wi-fi hot spots).8 while we know libraries have been heeding this advice when it comes to wi-fi hotspots, let’s look into what can be done when we consider ulc’s suggestion to consider different partners for your work. community partners an excellent example of what can be done with a coalition of community partners comes from detroit where a mesh wireless network was put in place to provide permanent broadband in a low-income neighborhood.9 the project is called the detroit community technology project. with the community-based mesh network, only one internet account is needed to provide access for multiple homes. the networks also enable people on the network to share resources on the network (calendar, files, bulletin board) and that data lives on their network, not in the cloud. one of the sponsors of the detroit community technology project is the allied media project (https://www.alliedmedia.org/) which also sponsors the casscowifi and the equitable internet initiative to get broadband and digital literacy training into several underserved areas. community networks (https://muninetworks.org/), a project of the institute for local selfreliance (https://ilsr.org/), describes several innovative projects in which communities partner with electric utilities. surry county, virginia, expects to extend broadband access to 6,700 households through a first-ever partnership between a utility (dominion energy virginia) and an electric cooperative (dominion energy). a similar project is underway with the northern neck cooperative and dominion energy.10 these initiatives are made possible due to some regulatory changes made in virginia (sb 966). according to community networks, there are 900 communities providing broadband connectivity locally (https://muninetworks.org/communitymap). but nineteen states still have barriers in place that discourage, if not outright prevent, local communities from investing in broadband. libraries in states where community networks are a viable option should be at the table, or perhaps setting the table, for discussions about how to bring broadband to the entire community not just into the library or dispatched one-at-a-time via wi-fi hotspots. this is an opportunity to convene community conversations focusing on the issue of broadband. library staff have been doing more and more of this type of outreach into the community and acting as facilitator. the ala has even produced a community conversation workbook (http://www.ala.org/tools/sites/ala.org.tools/files/content/ltc_convoguide_final_062414.pdf ) to support libraries just getting started. state partners in california, the governor recently issued executive order n-73-20 (https://www.gov.ca.gov/wp-content/uploads/2020/08/8.14.20-eo-n-73-20.pdf) directing state agencies to pursue a goal of 100 mbps download speed and

september 2020 what more can we to do address broadband inequity and poverty? | ayre 4 and departments to accelerate mapping and data collection, funding, deployment, and adoption of high-speed internet.11 this will undoubtedly create fertile ground for libraries to partner with other agencies and community organizations to advance this initiative. libraries are specifically called out to raise awareness of low-cost broadband options to their local community. every state has some kind of broadband task force or commission or advisory council (https://www.ncsl.org/research/telecommunications-and-information-technology/statebroadband-task-forces-commissions.aspx). this is another instance where libraries should be at the table. in my state, our state librarian is on the california broadband council. but many of these commissions do not have a representative from the library world which means they probably are not hearing from us. whether it is through your local library, your state library, or your state library association, it is important for librarians to build relationships with people on these commissions—if not get a seat on the commission themselves. national partners unless your community is blanketed with affordable broadband connectivity, it will be important that we continue to advocate nationally for the needs we see. in addition to helping the patron standing right in front of us checking out their hotspot, we also need to address the needs of the people who aren’t able to get to the library but are equally in need of access. our job is to make sure that any new initiatives undertaken by a new administration provide for free and equitable access to the internet for every household. extending e-rate (the federal communication commission’s program for making internet access more affordable for schools and libraries) isn’t enough. free (or at least affordable) broadband needs to be brought to every home. the electronic frontier foundation (eff) argues that fiber-to-the-home is the best option for consumers today because it will be easily upgradeable without touching the underlying cables and will support the next generation of applications (see https://www.eff.org/wp/case-fiber-hometoday-why-fiber-superior-medium-21st-century-broadband). libraries have worked with the eff on issues related to privacy and government transparency. maybe it’s time to team-up with them about broadband. global partners low earth orbit (leo) satellites could potentially bring broadband to everyone on earth.12 starlink (https://www.starlink.com/) is elon musk’s initiative and project kuiper

broadband inequity and poverty? | ayre 5 speak up, speak out, and get in the way these are just a few avenues that we, as professionals committed to free access to information, might pursue. i worry that we have not made enough noise about the problems we see in our communities that are a result of broadband inequity and digital poverty. and although virtually every library is doing something to address the problem, our efforts are no match for the magnitude of the problem. in a blog post on the brookings institution’s website, authors lara fishbane and adie tomer argue for a new agenda focused on comprehensive digital equity that includes (among other things) “building networks of local champions, ensuring community advocates, government officials, and private network providers share intelligence, debate priorities, and deploy new programming .”13 there are no better local champions and advocates for communities than the city or county librarians and their staffs. let’s treat this problem with the seriousness it deserves and at a scale that will be meaningful. to quote john lewis (as so many of us have since his death on july 17, 2020), it's time for us to “speak up, speak out, and get in the way.”14 we have to make it painfully clear to policymakers that libraries cannot bridge the digital divide with public access computers and hotspots. we need to tell our communities’ stories, convene conversations, and agitate for equitable broadband that is as readily available as water and electricity. endnotes 1 “libraries respond: covid-19 survey,” american

and libraries | march 2013 36 abstract interest in migrating to open-source integrated library systems is continually growing in libraries. along with the interest, lack of empirical research and evidence to compare the process of migration brings a lot of anxiety to the interested librarians. in this research, twenty librarians who have worked in libraries that migrated to open-source integrated library system (ils) or are in the process of migrating were interviewed. the interviews focused on their experiences and the lessons learned in the process of migration. the results from the interviews are used to create guidelines/best practices for each stage of the adoption process of an open-source ils. these guidelines will be helpful for librarians who want to research and adopt an open-source ils. introduction open-source software (oss) has become increasingly popular in libraries, and every year more libraries migrate to an open-source integrated library system.1 while there many discrete opensource applications used by libraries, this paper focuses on the integrated library system (ils), which supports core operations at most libraries. the two most popular open-source ilss in the united states are koha and evergreen, and they are being positioned as alternatives to proprietary ilss. 2 as open-source software becomes more widely used, it is not enough just to identify which software is the most appropriate for libraries, but it is also important to identify best practices, common problems, and misconceptions with the adoption of these software packages. the literature on open-source ilss is usually in the form of a case study from an individual library or a detailed account of one or two aspects of the process of selection, migration, and adoption. in our interactions with librarians from across the country, we found that there are no consolidated resources for researching different open-source ilss and for sharing the experiences of the people using them. librarians who are interested in open-source ils cannot find one resource that can give them an overview of the necessary information related to open-source ilss. in this research, we interviewed twenty librarians from different types and sizes of libraries and gathered their experiences to create generalized guidelines for the adoption of open-source ilss. these guidelines are at a broader level than one single case study and cover all the different stages of the adoption lifecycle. the experiences of librarians are useful for people who are evaluating opensource ilss as well as those who are in the process of adoption. learning from their experiences will help librarians to not have to reinvent the wheel. this type of research helps the librarians by empowering them with the information they need; also, it helps us in understanding the current status of this popular software. vandana singh (vandana@utk.edu) is assistant professor, school of information sciences, university of tennessee, knoxville, tennessee. mailto:vandana@utk.edu experiences of migrating to an open-source integrated library system | singh 37 literature review as mentioned earlier, most of the literature on open-source ils is practitioner-based and provides case studies or single steps in the process of adoption. these research studies and resources are useful but do not address the broad information needs of the librarians who are researching the topic of open-source ilss. every library is different, so no two libraries are going to take the same path in the adoption process. the usefulness of these articles depends on whether the searcher can find one in a similar environment. another issue is the amount of information given in these resources. often these papers discuss only one aspect of moving to an open-source ils, for example choosing the open-source ils. if they do cover the whole process, there is usually not enough detail to know how they did it. for example, morton-owens, hanson, and walls organize their paper into five sections: motivation and requirements analysis, software selection, configuration, training, and maintenance. 3 however, each section includes more main points than description. another relevant stream of literature includes those that compare different opensource ilss. these range from little more than links to different open-source projects to in-depth comparisons.4 for example, muller evaluated open-source communities for different ilss on forty criteria and then compared the ils on over eight hundred functions and features.5 these types of articles are very useful for those who are trying to become acquainted with the different opensource ilss that are available and are in the evaluation phase of the process. again, they are not helpful in understanding the entire process of adoption. some best practices articles such as tennant may be a little older, but his nine tips are still valid and very useful as a good foundation for anyone thinking about making the switch to open-source ils.6 what are the factors for moving to an open-source ils? another reason why an open-source ils appeals to libraries is its underlying philosophy: “open source and open access are philosophically linked to intellectual freedom, which is ultimately the mission of libraries.” 7 the other two common reasons are cost and functionality. the literature covering the decision to move to an open-source ils makes it clear that there is a wide variety of ways that libraries come to this decision. in espiau-bechetoille, bernon, bruley, and mousin, the consortium made the decision in four parts. 8 the article states that they initially determined that four open-source ilss met their needs (koha, emilda, gnuteca and evergreen), although it is somewhat vague as to how they determined that koha was the best for their situation. indeed, most of the article is about how the three libraries involved had to work together, coordinating and dividing responsibilities. bissels shares that money was the main reason that the complementary and alternative medicine library and information service (camlis) decided to migrate to koha.9 they explain the process of making that decision. camlis was being developed from nothing, which makes their situation different than most libraries, and hence the process is different as well. michigan is an area known for its number of evergreen libraries. much of that is due to michigan library consortium. dykhuis explains the long, involved process that led to a number of evergreen installations. 10 mlc provides services to michigan information technology and libraries | march 2013 38 libraries, such as training and support. when they started looking for an ils system that all libraries could use, the main concerns were cost and functionality, which are the two key aspects that are mentioned in any discussion about choosing an ils. kohn and mccloy state that they decided to migrate to a new ils due to frustration with their current ils and that they involved all six of their librarians in the decision-making process.11 dennison and lewis show another reason why people migrate to open-source ils.12 they say that the proprietary system they were using was much more complicated than they needed. in addition, because of staff turnover no one really understood the system. this lack of expertise combined with increasing annual costs led to the decision to move to an open-source ils. an important lesson to take from this article is that they included all six of their librarians in the decisionmaking process. for a smaller library where everyone is an expert in their area of the library, it is important to get everyone involved in order to make sure that important functions or needed capabilities are not overlooked. almost any library that chooses open-source ils will name cost as one of their primary reasons. functionality is usually what determines which ils they choose. riewe conducted a study where he asked why each library chose its current ils. 13 open source libraries responded most often with ability to customize, the freedom from vendor lock-in, portability, and cost. how does migration happen? there are two general ways to do a migration: all at once or in stages. kohn and mccloy discuss a three-phase migration.14 the reason for this method was to spread the cost over several years. they did the public website and federated catalog as phase one and did the backend part during phases two and three. when multiple libraries are involved, phased migration is more like what is described in dykhuis.15 in that case, first a pilot program was created where a few libraries migrated over to the new system. when that was successful, then more libraries migrated. in contrast to a phased migration, walls discusses a migration completed in three months.16 this time includes installation, testing, and configuration. one interesting decision they made was to migrate at the end of the fiscal year in order to limit the amount of acquisitions data to be migrated. dennison and lewis completed their migration in two months. in this migration, most of the work was done by the company that was hosting their system. 17 this limited the amount of expertise that the library staff needed and made the migration much smoother from their perspective. migration can also be an opportunity; for example, morton-owens, hanson, and walls mention that they used the migration to koha to synchronize circulation rules between the branches. 18 it was also used to weed out inactive patrons (anyone who had not used the library in two years). data migration can be a problem, though. in the old system, the location code had been used for where the item was within the branch library, what kind of item it was, and how it circulated, but experiences of migrating to an open-source integrated library system | singh 39 these are three separate fields in koha. however, to some extent these issues are true of any migration between different systems. the migration experience is not always of a smooth transition. one of the advantages of opensource is the ability to customize and to develop functions that are specific to your library. in the case of new york academy of medicine library (nyam) working with its consortium waldo (westchester academic library directors organization), it was the decision to have developments completed before migration that caused the problems.19 their migration schedule was delayed by a month, and even after the delay not all of the eleven key features were complete. in addition, their migration took place when liblime (a proprietary vendor) with whom they were working announced their separation from the koha open-source community, which caused additional confusion. there are a couple of lessons to take from this. first, if doing development, be sure that the time needed is built into the migration schedule. also, when choosing an ils, think about how many developments are going to be necessary to successfully run the ils in your environment. lastly, try to prioritize the developments to minimize the number needed before “going live.” what does the literature say about training? very little is available about the training process for open-source ils. in current studies, training can be done in two ways: either by buying training from a vendor, or doing it internally.20 dennison and lewis found that having staff work on the system together at first and then try it independently was the most successful. 21 they had a demonstration system to practice, which also helped. in addition to this self-training, they had onsite training done by module, which allowed staff to attend only the training that was relevant and needed for them. in all of the articles discussed in this section, only one talks about ongoing maintenance. 22 the two-paragraph section includes suggested methods and does not mention anything about the amount of time or expertise needed for ongoing maintenance. in summary, in this literature review we found that there is research about open-source ils but that there is a need for much more work in this area. it was found that research articles and practitioner pieces are available and talk about different aspects of the adoption process. the main reasons for adoption are identified. there are also a few scattered individual articles about the process of migration, training, and maintenance. there is a gap in the studies of open-source ils, and there is no comprehensive study that documents the process, explains the steps, and identifies best practices and challenges for librarians who are interested. data sources the objective for data collection was to collect data from a variety of library types and sizes in order to collect a wide range of data. e-mail invitations for interviews were sent to koha and evergreen discussion list and to several other library-related discussion list. the e-mail requested volunteers for a telephone interview to share their experiences with open-source integrated library systems. potential participants identified themselves as being willing to be interviewed for information technology and libraries | march 2013 40 the project via e-mail and were then contacted by researchers to set up times for phone interviews. the list of interview questions was e-mailed to the participants before the interviews so that they could review the questions and had enough time to reflect on their experiences. the interviews were conducted with librarians working in a variety of libraries, including nine libraries using evergreen and one in the process of migrating to evergreen. seven libraries were using koha, two were using other open-source ilss, and one was using a proprietary ils while evaluating opensource. public libraries were the most numerous with eleven respondents, while there were also four special libraries, three academic libraries, and one school library. researchers also requested information about the size of the library collection. seven libraries owned collections of less than 100,000 items, seven had collections of 100,001–999,999 items, and four libraries owned collections of over 1,000,000 items. geographically, the respondents ranged all over the united states and included one library located in afghanistan (although the ils was installed in the united states). table 1 details the description of the data. data collection method interviews were chosen as the primary means of data collection in order to gather rich information that could be analyzed using qualitative methods. researchers sought to interview professionals from a variety of library types and sizes in order to collect a variety of different experiences regarding the selection, implementation, and ongoing maintenance of open-source ils. interviewing was the chosen methodology for several reasons. first, the goal was to go past the practitioner articles to see what kinds of trends there are in the migration process. this requires getting experiences from multiple librarians. interviews provide the in-depth “case-study description” that we were looking for.23 in addition, the most useful aspect of interviewing is the ability to follow up on an answer that the participant gives.24 this ensures that the same type of information is gathered from every interview. this is unlike surveys where sometimes participants do not respond in a way that answers what the researcher really wants to know. in our case, we used telephone interviews due to the geographic dispersion of the participants. it allowed us to talk to librarians from all over the country instead of just within our area. the interview questions are listed in appendix a. data analysis methodology interviews were transcribed, and identifying information was then removed from each of the transcribed documents. the transcripts were then uploaded into dedoose (www.dedoose.com), a web-based analysis program supporting qualitative and mixed methods research. dedoose provides online excerpt selection, coding, and analysis by multiple researchers for multiple documents. the research team used an iterative process of qualitatively analyzing the resulting documents. this method used multiple reviews of the data to initially code large excerpts which were then analyzed twice more to extract common themes and ideas. researchers began by reviewing each document for quantitative information, including the library type, ils in use, experiences of migrating to an open-source integrated library system | singh 41 number of it staff, and size of the collection. this information was added as metadata descriptors to each document in dedoose. upon review of the transcriptions and in discussions about the interview process, researchers began a content analysis of the qualitative data. codes were created based on this initial analysis to aid in categorizing the data from the interviews. two coders coded the entire dataset, specifying categories and themes to the excerpts of the interview transcription. all of the excerpts from each coder were used to create two tests. each coder then took the test of the other's codes by choosing their own codes for each excerpt. researchers earned scores of .96 and .95 using cohen’s kappa statistic, indicating very high reliability. table 1. description of libraries library size (number of

| march 2013 42 results results from the interview questions were divided into eight categories identified as stages of migration, starting with evaluation of the ils, creation of a demonstration site, data preparation, identification of customization and development needs, data migration, staff training and user testing, and going live and long-term maintenance plans. best practices and challenges for each of the stages are presented below. this section begins with some general considerations gleaned from the responses. general consideration when migrating to an open-source ils • create awareness about open-source culture in your library—let them know what to expect. • develop it skills internally even if you use a vendor. • assess your staff’s abilities before committing. knowing what your staff can do will help determine whether you need to work with a vendor and to what degree or if you can do it alone. it is also a way to determine who is going to be on your migration team. • have a demonstration system; pre-migration, it can be used to test and train, and after migration it can be used to help find solutions to problems. this will also help develop skills internally. • communication is key. o if working with a vendor either as a single library or as a consortium, have a designated liaison with the vendor so all questions go through one person. in a consortium, ensure that everybody knows what is going on. • be prepared to commit a significant amount of staff time for testing, development, and migration, especially if you are not hiring a proprietary vendor for support. working with vendors • read contracts carefully. do not be afraid to ask questions and request changes. sometimes the other party has a completely different meaning for a word than you do. make sure you are on the same page. • ensure that there is an explicit timeline and procedure for the release of usable source code. • see that you are guaranteed and entitled to access the source code in case you need to switch developers, bring additional developers on board, or try to fix problems in-house. • provide specific examples when reporting problems. specific example will help the developers determine what the problem is and will help prevent any miscommunication. • designate a liaison between library staff and developers. the liaison will have to be someone who understands or can learn enough about what the developers are doing so that he or she can translate any problems or complaints from one group to the other. experiences of migrating to an open-source integrated library system | singh 43 • set up regular meetings for those involved in the migration project. regular meetings keep everyone focused and on task. they also provide an opportunity for questions, concerns, and problems to be addressed quickly. sample quote from interviews: one of the main things that came up is working with equinox, it was amazing. to start with, they were very, very helpful. and i had made an assumption, and i think the rest of us had, too, that we were working with, that this was developed by librarians, and that the terminology used would be library jargon. but that was not the case. we had some stumbling points over, we would say, okay, we want this, or this is a transaction, or that’s a bill, but that’s not what they called it. they didn’t call it a transaction, or they didn’t call it a bill. and so when we wrote the contract, we wrote it so that none of the patrons’ current checkout record would migrate, which is a big issue. and we didn’t realize that we weren’t using the right terminology in order to put that in the contract so that those current checkouts would move over with the migration and not just the record. stage 1—evaluation when making the decision of whether to migrate to open-source and which open-source ils is best for your library, the main things to start with are two questions: who makes the decision and on what basis. in practice, who makes the decision? • if a single library, one or two people make the decision, usually the library director and whoever is serving as the tech person. • if in a consortium, a committee makes the decision, often either the library directors or tech people. best practice suggestion: regardless of the size of the library system, even though these are the people making the decisions, you should always try to include as many groups as open-sourceible in the decision to move to open-source. which ils? • make a list of requirements based on your current system and a wish list of requirements for the new system. this is one area where you can involve more than just the system staff. asking the different departments (cataloging, acquisitions, and circulation) what their needs are ensures that the final decision includes everyone. • talk to other libraries that have made the move to open-source. they are a great resource for seeing how the system actually works, asking questions about the migration process, and providing information about open-source problems. if available, talk to a library that migrated from your current proprietary system. some systems are easier to migrate from than others, so this would be an opportunity to find out about any specific problems. information technology and libraries | march 2013 44 stage 2—set up a demonstration site • this is the most important guideline in the entire paper. create a demonstration site before making a final decision. o if there is still confusion in your team about which ils to use, setting up a demo site and installing koha and evergreen will be the best way to decide which one works for your situation. o doing at least one test migration will show what kind of data preparation needs to be done, usually by doing data mapping. data mapping is where you determine where the fields in your current system go when you move into the new system. another often-used term for data mapping is staging tables. o the demo site is also a good way to do staff training when needed. o the demo site also provides a way to determine what the best setup rules, policies, and settings are by testing them in advance. o it provides an opportunity to learn the processes of the different modules and how they differ from your library’s current practices. o most importantly, it serves as a test run for migration, which will make the actual migration go smoothly. sample quotes from interviews: do you think that the tests with the data and doing that really helped? oh yes, we were have had a disaster if we hadn’t done three tests and test loads. the pals office has done conversions multiple times before so they have it done, and we have good tech people. so they knew that the three tests loads would be a good thing. we did discover some of the tools that should be used, like for example one of the things that’s recommended for evergreen patron migration is to have a staging table, so you dump all your records into a database that you can then use to create the records in the evergreen tables. and you know we found out why that was important by running into a couple, a few problems with not being able to line up the data in the multiple fields. but you know that’s the sort of thing we expect. that’s pretty, i classify it as pretty typical migration learning, is finding out what works one way, what doesn’t the other. but you know that was a good thing because all the documents were saying, “you should use a staging table.” and we had to figure out ourselves why that was such a good idea. you should use a staging table for migration, i.e. move records into a database that is then used to create records in evergreen. it helps because some data doesn't line up in the same fields. it's a good idea to set up tables and rules far in advance in order to test before migration. it's very important to do data mapping very carefully because if you lose anything during migration it's difficult to get it back. check it to make sure that all the fields will be experiences of migrating to an open-source integrated library system | singh 45 transported correctly, and run tests while the old system is still up to make sure everything is there. stage 3—data preparation • clean up the data in advance. the better the data is, the easier it will transfer. this is also an opportunity to start fresh in a new system, so if there were inconsistencies or irritations in the old system this is a good time to fix it. o weeding—if you have records (either materials or patrons) that are out of date, get rid of them. the fewer the records, the easier migration will be. in addition, vendors often charge by record, so why pay for records you do not need? • consistency in data is key. if multiple people are working on the data, make sure they are working based on the same standards. • do a fine amnesty when migrating to a new system. depending on the systems (current and new), it is sometimes impossible or very difficult to transfer fine data into the new ils, so doing a fine amnesty will make the process simpler. • spot check data (testing, during, and after migration). catching problems early means there will be less work trying to fix problems later. sample quotes from interviews: i would say that if you’re considering converting to an ils software, that you’ve really got to do the data mapping very carefully with a fine-toothed comb because you don’t want to lose data. it’s too hard to get it back in. the data needs to be normalized so that the numbers of fields are uniform, names are in the correct order, and data is displayed correctly. the library has had to decide whether it is worthwhile to do things like getting rid of old abbreviations, etc. to make the data more easily understood. problems occur with old data if information such as note fields has been entered inconsistently. it's important to have procedures and to make sure everyone is following them. often things are put in different places, which causes a lot of trouble. they are doing a lot of cleanup of data, such as reducing the number of unique values in the case of some items that had a huge number of values in a drop down list. would like to spend more time on data cleanup but need to go ahead and get data migrated. stage 4—development/customization • one benefit of using an open-source ils is that any development done by any library comes back to the community, so often if you want something done, someone else might have already created that functionality and you can use it. information technology and libraries | march 2013 46 • develop partnerships. often if you want a specific development, someone else does too. if your staff does not have the expertise, then you could provide more of the funding and the partner could provide the tech skills or vice versa. partnerships mean the development will cost less than if you did it alone. • grant money is also available for open-source development and may be another funding option. sample quotes from interviews: the library does its own minor customizations and uses equinox for major jobs. they will lay out and prepare everything then hire equinox to write and implement new code. the library tries not to do things on its own but always looks for partnerships when doing any customizations. that way libraries that have similar needs can share resources. stage 5—migration process • write workflows and policies/rules beforehand. writing these when working on the demo site should provide step-by-step instructions on how to do the final migration. • having regular meetings during the migration process ensures that everyone stays on the same page and prevents miscommunications that will slow down the process. • if many libraries are involved, migration in waves will make things easier. this is generally a situation with a statewide consortium. usually there is a pilot migration of four to eight libraries, then after that, each wave gets a little bigger as the system becomes more practiced. this can also be a useful model if the libraries involved in the consortium are accepting the migration at different rates. • for a consortium that is coming from multiple ilss, having a vendor will make it easier. this is not to say that it could not be done without a vendor, but migrating from system a is going to be different than migrating from system b. this increases the complexity, which can make working with a vendor more cost effective. stage 6—staff training and user testing • who does the training? there are two main ways: by a vendor or internally. o if trained by a vendor, there are two options:  the vendor sends someone to the library to conduct training.  the library sends someone to the vendor for training and then he or she comes back and trains the rest of the staff. o if trained internally, there are a lot of training materials available. there are several libraries that have created their own materials and then made them available online. this is another time where having contacts with other libraries can help in using common resources. experiences of migrating to an open-source integrated library system | singh 47 • documentation is important for training. the best way is to find what documentation is already available and then customize it for your system. • do training fairly close to the “go live” date. • use a day or two for training. if a consortium is spread out geographically, use webinars and wikis. • when doing training, have specific tasks to do. this can be done a few ways. o do the specific tasks at the training. o demonstrate the tasks at training and then give “homework” where the staff does the specific tasks independently. to implement this option, staff has to have access to a demo system. o have staff try the tests on their own and use the training session for questions or problems they had. sample quotes from interviews: well we had, we hired equinox to come and do 2 days of training with us. so they’re here and did hands-on training with us. and then we also, they provided some packets of exercises that people could do on their own. and we had the system up and running in the background so that they could play with it about a week before we actually went live to the public so that they could get used to it, figure out how things worked, and work with it a little bit so they could answer questions before the public came and said, hey, how do i find my record, and i can’t get into this anymore. and the training was really good, but the hands-on was the best. and it’s not a difficult system to work, but you just need a little experience with it before it makes sense. evergreen runs a test server that anybody can download the staff client for that and work in their test server and just examine all of the records and how the system works, to figure out our workflows. we looked up documentation online—evergreen, indiana, pines, various places—copied the documentation they so graciously hosted online for everybody to use, went through it, found what worked for us. those couple staff members worked with other staff. we printed out kind of our little how-to guides for other people, depending on which worked, and told them they’re going to sit down, we’ve got terminals set up here, sit down and learn it. the admin person, she went through some quite detailed training. she went to atlanta and had training from equinox on a lot of aspects of evergreen. and then we also, she came back, and then she did training for all the libraries in the consortium, kind of an intensive day-long or half-day-long thing that she offered in several different central geographic locations so that all the libraries would have a chance to go and attend without having to drive too far. and we also did webinars, we got a couple webinars for the real outlying libraries. and we also have ongoing weekly webinars. and we have a wiki set up where we put all the information in the online manual and stuff like that. information technology and libraries | march 2013 48 all the training sessions were recorded, and so we had them on cd for new people coming on board. marketing for patrons • most libraries have not done anything elaborate, generally just announcements through posters, local papers, flyers, and on websites. • if the migration is greatly changing the situation for patrons, then more marketing is needed. • set up a demo computer for patrons to try or hold classes once the system is up. training for patrons • most libraries did not find this necessary. either the system is easy to use or it is set up to look like the old system. • if training patrons, create online tutorials. stage 7—“go live” and after • if possible, have your old system running for a month or two until you are sure that all the data got migrated over properly. sample quote from interviews: check it to make sure that all the fields will be transported correctly, and run tests while the old system is still up to make sure everything is there. maintenance—library staff (this assumes a migration being done in-house with little to no vendor support.) • staff has to have the technical knowledge (linux, sql, and coding). • often the money saved from moving to open-source is used to pay for additional staff. • most time is not spent on maintenance but on customization, updates, or problem-solving. maintenance—vendor • often start with higher vendor support, which lessens as the staff learns and develops expertise. discussion and conclusion interviews with twenty librarians from different settings provided insight into the process of the adoption of open-source ils and were used to develop the guidelines presented in this paper. these guidelines are not intended to serve as a complete guide to the process of adoption but are meant to give interested librarians an overview of the process. these guidelines can help libraries prepare themselves for the research and adoption far before they delve into the process. since these guidelines are all based in the real-life adoption experiences of libraries, they provide insight experiences of migrating to an open-source integrated library system | singh 49 into the challenges as well as the opportunities in the process. these guidelines can be used to develop an adoption plan and requirements for the adoption process. in future research, we are working to create adoption blueprints and total cost of ownership assessments (with and without vendors) for libraries of different sizes and types. also, as part of this research we have developed an information portal that contains resources that will help librarians in each phase of the process of open-source ils adoption. the information portal along with these guidelines will fill a very important gap in the resources available for open-source ils adoption. the url for the portal is not being provided in this paper to ensure anonymous review. references 1. marshall breeding, “automation marketplace

(unfortunately only one full catalog card is illustrated in the entire book.) it is in this section, more than in any other, where the differences between british and american cataloging become obvious. british descriptive cataloging varies in so many ways from its american counterpart that a beginning student in an american library school would be quite confused by these variations. the next section consists of twenty-five pages and is devoted to the basic rules on entries and headings. examples are used to illustrate the rules and the authors point out some differences between the british and american texts of the aacr. the remaining seventy pages contain the forty reproduced title pages which are followed by some commentary and a key corresponding to each title page. these title pages give the student a wide range of experience in transcribing the proper information onto the card and in determining main and added entries. even though this book is an excellent introduction to the rudiments of descriptive cataloging and the determination of main and added entries, book reviews 59 its use of british descriptive cataloging precludes its being widely adopted in beginning cataloging courses in american library schools. donald /. l ehnus centmlized processing for academic librm·ies. by richard m. dougherty and joan m. maier. metuchen, n.j.: scarecrow press, 1971. 254p. $10.00 this is the final report of the colorado academic libraries book processing center ( calbpc) two-part study investigating centralized processing. phase i, reported by laurence leonard, maier, and dougherty in centralized book processing, scarecrow, 1969, was basically a feasibility study, whereas this final report describes the beginning six months of operations that tested the phase i recommendations. partially funded by the national science foundation, the experiment measured anticipated time and cost savings, monitored acquisitions and cataloging operations, and tested product acceptability for six libraries participating in the 1969, six-month study. even though centralized book processing might hold little appeal for the reader, this volume nonetheless is valuable to technical service heads because of its above average sophistication in applying a systems analysis approach to technical services problems. the authors objectively report their findings, outlining in detail the mistakes, the unanticipated problem areas, and what they believed to be the successes. from the start the authors encountered problems with scheduling. by the time the experiment began most participants had a large portion of their book money encumbered, and the center was forced to accept cataloging arrearages in addition to book order requests. those who did send in orders did not conform to patterns predicted in phase i. instead, the center was used as a source of obtaining more difficult materials, including foreign language items. it was discovered that in actual practice calbpc had no impact on discounts received from vendors. the vendor performance study lacked relevancy because it was based upon the date invoices were cleared for payment rather than the date books were received in house. in evaluating the total processing time, four libraries reduced their time lag by participating in the center's centralized processing, and the cost of processing the average book was reduced from $3.10 to $2.63. the product acceptance study showed that the physical processing was only partially accepted with most of the libraries modifying a truncated title that was printed on the book card and book pocket as a by-product of the automated financial subsystem. other local modifications were made on books processed by the center but that cost or local error correction costs were not reported in the study. calbpc's automated financial subsystem was beseiged with many problems resulting from lack of programming foresight and adequate consulting 60 journal of library automation vol. 5/1 march, 1972 by those who had previously designed such systems. individuals interested in the automation of acquisitions should read this section of the report. calbpc's problems were typically those of building exceptions to exceptions in order to accommodate unanticipated program omissio.ns. simply not recognizing that books could be processed before invoices were paid caused delays and bottlenecks of such magnitude that procedures had to be devised to circumvent requirements of the automated subsystem. many recommendations were particularly relevant to cooperative ventures. in formulating processing specifications such as call number format and abbreviation standardization, calbpc had not anticipated the infinite local variations they would have to accommodate. they quickly recognized the need for both greater quality control to minimize errors within the system and better communications and educational programs for participants. a reoccurring message was that librarians emphasized the esthetics of catalog cards rather than the content, thus a recommendation was made to investigate whether a positive correlation exists between the esthetics of the product and the quality of the library service. the authors emphasized that a cooperative program depends more upon competencies and willingness of individuals than the technical aspects of the operations. some diversification of services was called for but no mention was made of the possibilities of an on-line system. it was felt that in future operations the center should accept orders for out-of-print and audiovisual materials. those libraries participating in approval programs had received no benefit by having books sent first to the center, thus it was suggested that the center forward those libraries a bibliographic packet only and that the approval books bypass the center. this well-documented study, half of which is devoted to charts and appendix materials, concluded its recommendations with a positive evaluation of the service the center had performed and suggested that public and school libraries should also be participants. ann allan accessible, dynamic web content using instagram jaci wilkinson information technology and libraries | march 2018 19 jaci wilkinson (jaci.wilkinson@umontana.edu) is web services librarian at the university of montana. abstract this is a case study in dynamic content creation using instagram’s application program interface (api). an embedded feed of the mansfield library archives and special collections’ (asc) most recent instagram posts was created for their website’s homepage. the process to harness instagram’s api highlighted competing interests: web services’ desire to most efficiently manage content, asc staff’s investment in the latest social media trends, and everyone’s institutional commitment to accessibility. introduction the mansfield library archives and special collections (asc) at the university of montana had a simple enough request. their homepage had been static for years and it was not possible to add more content creation to anyone’s workload. however, they had a robust instagram account with more than one thousand followers. was there any way to synchronize workflows with an instagram embed on the homepage? the solution was more complicated than we thought. we developed an instagram embed, but in the process grappled with some fundamental questions of technology in the library. how do we streamline the creation and sharing of ephemeral, dynamic content? how do we reconcile web accessibility standards with the innovative new platforms we want to incorporate on our websites? libraries have invested heavily in social media to improve their approachability, reduce library anxiety, and interact with their users. at the mansfield library, this investment has paid off for asc. this unit was an early adaptor of instagram, a photo and short video–sharing application with the public or approved followers. the asc instagram account launched in january 2015, and staff quickly settled on the persona of “banjo cat” to share collection items and relevant history. banjo cat was inspired by a whimsical nineteenth-century photograph in asc of a cat playing a banjo (see figure 1). asc now has about 1,200 followers including many other libraries, archives, and special collections. in fact, connecting to a wider community of similar institutions was a driving factor in creating an instagram account. the asc staff member who updates the account said, while we have lots of interactions with patrons on facebook we have basically zero interactions with other institutions. instagram is all about interacting with other institutions, sharing ideas for posts, commenting on posts. so by learning about this community and participating and interacting with it we are able to . . . learn about programs and ideas that we would probably not have access to otherwise. 1 mailto:jaci.wilkinson@umontana.edu accessible, dynamic web content using instagram | wilkinson 20 https://doi.org/10.6017/ital.v37i1.10230 figure 1. banjo cat by l. a. de ribas. mansfield library archives and special collections. 1880s. but while asc’s social media thrived, its website was bereft of dynamic content. given that the asc homepage is the ninth most visited page on the library site, it felt like a wasted opportunity to let such a highly trafficked area lack engaging, current, and appealing content. it seemed only natural to harness the energy put into the asc instagram account and embed that same light-hearted, community-oriented, and collection-focused content on the asc homepage. literature review libraries are enthusiastic adopters of social media; one study even shows that as of 2013, 94 percent of academic libraries had a social media presence.2 a 2006 library journal article observed the following about myspace, then a popular social media platform: “given the popularity and reach of this powerful social network, libraries have a chance to be leaders on their college campuses and in the larger community by realizing the possibilities of using social networking sites like myspace to bring their services to the public.” 3 this open-minded spirit and willingness to try new technology trends was shrewd. pew research reports that as of 2016, 69 percent of americans use some type of social media. 4 social media use has grown more representative of the population: the percentage of older adults on at least one social media site continues to increase.5 for academic libraries, the pull of facebook was immediately strong because of the initial requirement for users to have a .edu address. academic libraries very early on attempted to connect with students about services, resources, and spaces using facebook.6 information technology and libraries | march 2018 21 dynamic content is a gateway to building interest toward and buy-in to an institution. in user experience literature, “user delight” is “a positive emotional affect that a user may have when interacting with a device or interface.”7 in walter’s hierarchy of user needs, pleasure tops all other needs.8 figure 2. aaron walter’s hierarchy of user needs, from therese fessenden, “a theory of user delight: why usability is the foundation for delightful experiences,” nielsen norman group, march 25, 2017, https://www.nngroup.com/articles/theory-user-delight/. using social media to engage users with special collections has its own niche. special collections are typically housed in closed stacks and have no digital equivalent. often the materials housed in special collections are rare, fragile, exotic, beautiful, and unusual; a study of library blogs and social media found that those with higher aesthetic value received more visitors and more revisits.9 social media “gives users an idea of what the collection offers while it promotes and potentially gains foot traffic.”10 it has even been suggested that social media gives special collections the opportunity to stand in when digitization isn’t possible: “instead of digitizing a whole collection, librarians can highlight important parts of the collection with a snippet of its history.”11 in creating ucla’s powell library instagram account, librarian danielle salomon https://www.nngroup.com/articles/theory-user-delight/ accessible, dynamic web content using instagram | wilkinson 22 https://doi.org/10.6017/ital.v37i1.10230 writes, “special collections items and digital library images can be a treasure trove of social media content. one of our library’s goals is to increase students’ exposure to special collections items, so we draw heavily from these collections.”12 instagram is a relative newcomer to social media, but it has been consistently successful since its inception in 2010.13 as of 2016, 28 percent of americans use instagram, up from 11 percent in 2013.14 facebook bought instagram in 2012 and has since bolstered the application’s success by making the two platforms easy to navigate and share between. after vine, a short video application, was shuttered in 2017, instagram’s ability to take and post short videos has increased its value. instagram is distinct in that it is mobile-dependent: it is difficult to run the application through a web browser, and only one device can operate an instagram account. within the library community, instagram’s adoption has been strongest in academic libraries. this is tied to the high number of instagram users who are college-age.15 another reason libraries select instagram is because it has more diverse users than other social media applications, specifically african americans and latinos.16 in a 2016 study, instagram was the second-most pick among college students at western oregon university when asked what social media application the library should use (twitter came in first). the most popular use of instagram in academic libraries is familiarizing students with services, resources, and spaces. uses include first-year instruction activities to combat library anxiety and mini-contests that ask users to identify what posted photos are of.17 ucla’s powell library discovered students posting instagram photos of their spaces, so they initially joined to repost those photos and interact with those users. instagram makes a library seem approachable. librarian joanna hare reflected on this discovery: “instagram is really powerful in that respect because you can just snap a few photos [and] show what’s going on . . . so that students don’t view the library as being intimidating.” 18 approachability is augmented by delegating photography and posting tasks to library student employees. social media is less often seen as a way to help create dynamic content for a library’s website. the exceptions to this trend have come from institutions with substantial technology resources. north carolina state university created an open source software that adds photos posted by anyone on instagram to a library photo collection when a certain hashtag is used.19 the university of nebraska’s calvin t. ryan library created an rss feed that disseminates blog posts to twitter, facebook, and the library homepage. posts from followed accounts in twitter and facebook are also a part of the resulting feed. the rss feed requires use of a third-party tool called dlvr.it (https://dlvrit.com/), which supports many other social media applications, but not instagram. a notable absence in literature on social media use in libraries is any mention of accessibility concerns. the “improving the accessibility of social media for public service” toolkit developed by a group of us government offices is a useful resource that includes specific guidelines on making instagram posts more accessible.20 the toolkit explains that “more and more organizations are using social media to conduct outreach, recruit job candidates and encourage workplace productivity. . . . but not all social media content is accessible to people with certain disabilities, which limits the reach and effectiveness of these platforms. and with 20% of the population estimated to have a disability, government agencies have an obligation to ensure that their messages, services and products are as inclusive as possible.”21 given the stated importance of social media in library literature, the lack of conversation about accessibility and social media is a barrier to inclusivity. https://dlvrit.com/ information technology and libraries | march 2018 23 mansfield library archives and special collections’ instagram feed dynamic content was lacking from any part of the asc website, but staff had a dearth of time and knowledge of the content management system to create web content. there was a drive to solve this problem because a new web services librarian had recently been hired. when the web services librarian learned of asc’s thriving instagram presence, she pursued the possibility of including that content on the asc website. she felt that, in addition to being more efficient, content creation should stay in-house given the highly specialized nature of asc’s collections, spaces, and resources. the ideal solution would allow asc staff to create and manage an instagram feed unassisted; the web services librarian sought the simplest possible solution for them. our content management system and instagram’s developer website were first consulted with the hope that one provided an automated embed or plugin. our content management system, cascade, could pull in content from facebook and twitter but not instagram, and instagram did not have an automated feed creator. after more research, we learned that third-party instagram feed embeds are the only possible way to create an instagram feed without using instagram’s api. the api was considered a last-resort option because we knew that asc staff could not manage the code themselves. the idea of using any third-party service was undesirable because of a lack of control, stability, and accessibility. if the service has technical issues or goes out of business, it would be very noticeable given the visibility of asc’s homepage. in 2012, a student advocacy organization at the university of montana filed a civil rights complaint with the us department of education focusing on disabled students’ unequal access to electronic and information technologies. since then, the mansfield library has been proactive to eliminate barriers to access.22 given this history, we are wary of the accessibility of third-party applications to someone using assistive technology, most likely, a screen reader. juicer (https://www.juicer.io/), for example, is a freely available service for an instagram feed but in exchange it retains its branding prominently at the top of the feed. an example of juicer in use can be found on the home page of the baltimore aquarium (http://aqua.org/). tests of juicer showed that it was not accessible for a screen reader. finally, it didn’t fit our need: juicer curated posts from other users depending on the hashtags and reposts, but we only wanted to feature our own content. the unpredictability of other accounts’ posts ending up on the asc homepage was not desirable. instagram’s developer site did not make finding a solution easy. the page titled “embedding” is about embedding individual posts on a webpage, not a whole feed.23 this content does not even link out to an explanation of how to embed a feed. the “authentication” page is where the process begins because calling the api requires a token an authenticated instagram account user.24 a user is authenticated by creating a client id and then receiving an access token. another interesting roadblock provided by the instagram developer site is that the “authentication” page provides no further information about using the access token to call the api. it took outside research to finally figure out the steps needed to make the api requests for asc’s feed.25 php code is used to call the api and copy the three most recent asc instagram posts to a local server file. (using javascript to call the api is a poor choice because that code will make the account’s access token public. if anyone sees this token they can use it themselves to pull your feed using the instagram api.) css replicates the look and feel of instagram with white, minimalistic icons and a simple photo display https://www.juicer.io/ http://aqua.org/ accessible, dynamic web content using instagram | wilkinson 24 https://doi.org/10.6017/ital.v37i1.10230 that darkens and shows the beginning of the description when a user’s mouse hovers over it. all code from this project is freely available in github.26 there is a catch to this embedded feed process. the directions given through instagram and by the online sources we used only took us to sandbox mode (in web development, sandbox refers to a restricted or test version of a final product). in sandbox, instagram limits the number of requests to the api. unfortunately, a request was made every time someone went to the asc page. the initial feed stopped working in minutes because we did not realize this limitation of sandbox mode meant. another look at the instagram developer site taught us that the only way to leave sandbox was to have our “app,” as instagram called it, reviewed.27 in other words, instagram has only set up their api to be used for full application development (like juicer). we decided not to leave sandbox mode because of uncertainty about what instagram’s review process would entail. if our app was rejected, would they force us to discontinue our work? the timeline for the approval process was also uncertain. distrust and uncertainty, unfortunately, guided our decision-making at this stage. instead of undergoing the review process, the php code was reconfigured to call the api only once a day. this made the feed less dynamic because it was not updating in real time. f or our purposes this was not a problem; the asc instagram account is updated at most once or twice a week anyway. as a result, we are “scraping” asc’s instagram account. although “crawling, scraping, and caching” are prohibited by instagram’s terms of use, other instagram feeds in github have similar workarounds and point out that a plugin/scraper “uses (the) same endpoint that instagram is using in their own site, so it’s arguable if the toc [terms of use] can prohibit the use of openly available information.”28 while figuring out how to work with the instagram api, a major accessibility roadblock cropped up: there was no place for the alt text—descriptive information about the image that is used by assistive technologies for users with low vision. besides taking or uploading a photo, the only other actions offered to create a new post were to write a caption, tag people, or add a location. only the caption allowed for a text string. without alt text, not only is the instagram feed unintelligible to a screen reader but it disturbs a screen reader user’s interaction with all other content on that page. an asc staff member discovered a solution when she noticed a joshua tree national park instagram post with alt text at the bottom of the caption. although initially put off by the “wordiness,” we concluded this was the only logical way to move forward. the benefits to this format of alt text took focus as we moved through the project: the asc staff member was able to choose the desired alt text without any additional steps or skills, and we grew to relish the opportunity to explain to curious users what the #alttext hashtag meant and why it was important to us. php code isolates all text after #alttext and displays that as the alt text to a screen reader. since the instagram feed was implemented, it has been interesting to follow how the instagram developer site has changed and grown. although facebook has owned instagram for five years, the instagram developer site is only now starting to link out to facebook developer content. most recently, the instagram developer site has been advertising the instagram graph api for use by business accounts. this type of development is useless for us because we have a personal instagram account, not a business account. and the function of the instagram graph api is focused on the internal user and analytics, not the end user and user experience. even if the instagram graph api was available for personal accounts, it is worth asking if this type of data collection would be of use to an organization that doesn’t have the labor of a devoted marketing team. information technology and libraries | march 2018 25 dynamic content through social media and web content provides opportunities to create user delight because it focuses on visually appealing, fun, timely, and interesting information. for archives, special collections, and other cultural heritage institutions, this content is particularly useful because it provides a look into collections that are interesting and rare but also fragile and housed in closed stacks. these positives are tempered by the reality many of these institutions face: budgets are tight, staffs are small, and technical expertise might be lacking. this paper demonstrates how important and useful social media is to create dynamic website content. unfortunately, there is a gap in library literature on accessibility and social media; although social media content is ephemeral or lacks specific utility, libraries need to pay more attention to the various ways users access resources and information through social media, especially if that same content appears on the institution’s website. the asc’s embedded homepage instagram feed fits their needs, is accessible, and builds community around their unique collections. by providing all the code created in this project in github,29 including the css we used, our hope is that institutions interested in this instagram feed model could replicate it for their own purposes without extensive technical support. acknowledgments i am thankful for the expertise of carlie magill, donna mccrea, and wes samson. without them this project would not have been possible. references 1 carlie magill,

archives and special collections’ instagram feed acknowledgments references animated subject maps for book collections tim donahue information technology and libraries | june 2013 7 abstract of our two primary textual formats, articles by far have received the most fiscal and technological support in recent decades. meanwhile, our more traditional format, the book, seems in some ways to already be treated as a languishing symbol of the past. the development of opacs and the abandonment of card catalogs in the 1980s and 1990s is the seminal evolution in print monograph access, but little else has changed. to help users locate books by call number and browse the collection by subject, animated subject maps were created. while the initial aim is a practical one, helping users to locate books and subjects, the subject maps also reveal the knowledge organization of the physical library, which it displays in a way that can be meaningful to faculty, students, and other community members. we can do more with current technologies to assist and enrich the experience of users searching and browsing for books. the subject map is presented as an example of how we can do more in this regard. lc classification, books, and library stacks during the last few decades of technological evolution in libraries, we have helped facilitate a seismic shift from print-based to digital research. our library websites are jammed with electronic resources, digital collection components, database links, virtual reference assistance, online tutorials, and mobile apps. collection budgets too have shifted from a print to electronic focus. many libraries are now spending less than 20 percent of their material budgets on print monographs. and yet, our stacks are still filled with books that often take up more than fifty percent of our library spaces. knowledge organization schemas have also evolved in libraries. we have subject lists to help users to decide on which databases to select that reflect current disciplines and majors in higher education. internal database navigation continues to evolve in terms of limits, fields, and subject searching. web searching is based on the contemporary keyword approach where “everything is miscellaneous” and need not be organized, but nationwide, billions of books still sit on shelves according to dewey or library of congress classification systems that were initially developed over a century ago. some say these organizing systems are woefully antiquated and do not reflect our contemporary post-modern realities, though they still amply serve their purpose to assign call number locations for our books. we hear scant little of plans to update these classification schemes. why invest more time, energy, and resources on revamped organization schemes for libraries? the hathitrust now contains the tim donahue (tdonahue@montana.edu) is assistant professor/instruction librarian, montana state university, bozeman, mt. animated subject maps for book collections | donahue 8 scanned text of more than ten million books. google claims there are almost 130 million published titles in the world and intends to digitize all of them.1 what will happen to our physical book collections? how long will they reside on our library shelves? how long will they be located using the dewey and lc systems? is the library a shrinking organism? profession-wide, there seems to be no concrete vision in regards to the future of our book collections. there is, of course, general acknowledgement that acquisition of e-books will increase as print acquisitions decrease and that, overall, print collections will accordingly shrink to reflect the growing digital nature of knowledge consumption. but for now and into the foreseeable future these billions of monographs remain on our shelves in the same locations our call number systems assigned to them decades ago. and while online library users are now able to utilize an array of electronic access delivery systems and web technologies for their article research and consumption, book seekers still need a call number. books and articles have been our two primary textual formats for centuries. articles have moved into the digital realm more fleetly than their lengthier counterparts. their briefer length, the cyclical serial publication process, and the evolution of database containment and access have enabled, in a relatively short time, a migration from print to primarily digital access. books, however, are accessed in much the same way they were a hundred years ago. the development of opacs in the 1980s and 1990s and abandonment of card catalogs is the seminal evolution in print monograph access, but little else has changed.2 once a call number is attained, the rest of the process remains physical, usually requiring pencil, paper, feet, sometimes a librarian, and a trip through the library until the object itself is found and pulled from the shelf. so while the process of article acquisition may employ a plethora of finding aids, keyword searching, database features, full text availability, and various delivery methods through our richly developed websites, beyond the opac and possibly a static online map, book seekers are on their own or need a librarian in what may seem a meaningless labyrinth of stacks and shelves. while the primary and most practical purpose of our classification schemes is to provide an assigned call number for book finding, these organizational outlines create an order to the layout of our stacks that maps a universe of knowledge within our library walls. this structure of knowledge reveals a meaning to our collections that includes the colocation of books by topic and proximity of related subjects. these features enhance the browsing process and often lead to the act of serendipitous discovery. to locate a book by call number, a user may consult library floor plans, which are typically limited to broad ranges or lc main classes, then rely on stack-end cards to home in on the exact stack location. to browse books by subject without using the catalog, a user typically must rely on a combination of floor plans and lc outline posters if they exist at all. often, informed browsing by subject cannot take place without a visit to the reference desk for mediation by a librarian. even then, many librarians are barely familiar with their book collection’s organizational structure and are reticent to recommend broad subject browsing. information technology and libraries | june 2013 9 purpose and description of the subject map to help users locate books by call number and browse the collection by subject, animated subject maps were created at skidmore college and montana state university. displaying overhead views of library floors, users mouse over stacks to reveal the lc sub-classes located within. alternatively, they may browse and select lc subject headings to see which stacks contain them. the lc outline contains 21 main subject classes and 224 sub-classes, corresponding to the first two elements of a book call number. on stack mouse-over, three items are displayed: the call number by range, the main subject heading, and all sub-classes contained within the stack. when using the browse by subject option, users select and click an lc main class and the stacks where this class is located are highlighted. while the initial aim is a practical one, helping users to locate books and subjects, the subject map also reveals the knowledge organization of the physical library, which it displays in a way that can be meaningful to faculty, students, and other community members. the map also provides local electronic access to the lc classification outline. at both institutions the maps are linked from prominent web locations and electronic points of need that are relevant and proximate to other book searching functions and tools. figure 1. skidmore college subject map showing stack mouse-over display. animated subject maps for book collections | donahue 10 figure 2. montana state university subject map showing stack mouse-over display. design rationale and methodology the inspiration for the subject map started with a question: what if users could see on a map where individual subjects were located within the library? most library maps examined were limited to lc main classes or broad ranges denoting wide swaths of call numbers. including hundreds of lc subclasses would convolute and clutter a floor map beyond usability. but what if an online map contained each individual stack and only upon user-activation was the information revealed, saving space and avoiding clutter? such a map should be as devoid of congestion as possible and focus the user’s attention on library stack locations and lc classification. working from existing maps and architectural blueprints of the library building, a basic perimeter was rendered using adobe illustrator and indesign software. these perimeters were then imported into adobe flash and a new .fla file created. library stacks were then measured, counted, and added as a separate layer within each floor perimeter. basic location elements such as stairways, elevators, and doors were added for locational reference points. each stack was then programmed as a button with basic rollover functionality. flash actionscript was coded so that the correct call number, main class, and sub-class information appear within the interface upon rollover activation. this functionality accounts for the stack searching ability of the subject map. information technology and libraries | june 2013 11 additionally, the lc outline was made searchable within the map so that users can mouse over subjects and upon clicking, see what stacks contain those main classes. this functionality accounts for the subject searching ability of the map. left-hand navigation was built in so users can toggle between these two main search functions. maintaining visual minimalism and simplicity was a priority and inclinations to render the map more comprehensively were resisted in order to maximize attention to subject and stack information. black, white, and gray colors were chosen to enhance the contrast of the map and aid the user’s eye for quick and clear use. other relevant links and instructional context were added to the left-hand navigation including links to the catalog, official lc outline, and library homepage. finally, after uploading to the local server and creating a simple url, links to the subject map were established in prominent and meaningful points of need within the library website. user acceptance once the subject map was completed and links to it were made public, a brief demonstration was provided for reference team members who began showing it to users at the reference desk. initial reaction was enthusiastic. students thought it was “cool” and enjoyed “playing with it.” one reported, “i didn’t know the library actually made sense like that. it’s neat to see the logic about where things are.” another student said, “now i can see where all the books on buddhism are!” faculty, too, were pleased. though faculty members typically know a little about lc classification, they are not accustomed to seeing it visualized and grafted onto their institutional library’s stacks. making transparent the intellectual organization of the library for other faculty can bolster their confidence in our order and structure. professors are often pleased to see their discipline’s place within our stacks and where related subjects are located. the most positive praise for the subject map, however, comes from the sense of convenience it lends. many comments express appreciation for the ability to directly locate an individual book stack. because primary directional and finding elements like stairs and elevators are included in the maps, users are able to see the exact path that leads to the book they are seeking. for those not interested in browsing, in a hurry, or challenged in terms of mobility, the subject map is a time and energy saver. some users however have reported frustration with the sensitivity required for the mouse-over functions. others desire a more detailed level of searching beyond the sub-class level. one user pointed out that the subject map was of no help to the blind. multiple uses and internal applications the primary use and most obvious application of the subject map is as a reference tool. as a front line finding aid, librarians and other public service staff at reference, circulation, or other help desks can easily and conveniently deploy the map to point users in the right direction and orient them to the book collection. in library instruction sessions, the subject map is not only a practical local resource worth pointing out, but also serves as an example of applied knowledge organization. when accompanying a demonstration of the library catalog, the map is not only a valuable finding aid, but adds a layer of meaning as well. students who understand the map are animated subject maps for book collections | donahue 12 not only more able to browse and locate books, but learn that a call number represents a detailed subject meaning as well as locational device. used in conjunction with a tour, the map reinforces the layout of library shelves and helps to bridge the divide between electronic resources and physical retrieval. the subject map facilitates a concrete and visual introduction to the lc classification outline, a knowledge of which can be applied to most college and research libraries in the united states. the subject map can also be of assistance with collection development. perusal of the map can reveal relative strengths and weaknesses within the collection. subject liaisons and bibliographers may use the map to home in on and visualize their assigned areas. circulation staff and stacks maintenance workers find the map useful for book retrieval, shifting projects, and in the training and acclimation of new workers to the library. the subject map has proven to be a useful reference for library redesign and space planning considerations. at information fairs and promotional events where devices or projection screens are available, the map has served as a talking point and promotional piece of digital outreach. the map has been demonstrated by information science professors to lis graduate students as an example of applied knowledge organization in libraries. recently, a newly hired incoming library dean commented that the map helped him “get to know the book collection” and familiarized him with the library. figure 3.

subjects may reside on the same shelves during an entire library’s lifetime. in this case, a subject map can be designed once and never edited. but, of course, most library buildings go through changes and evolutions. in many libraries, collection shifting seems to be ongoing. book collections wax and wane. certain subjects expand with their times, while others shrink in irrelevancy. weeding does not affect all subjects and stacks equally and adjustments to shelves and end cards are necessary. in addition to the transitions of weeding and shifting, sometimes whole floors are reconfigured. in the library commons era of the last few decades, substantial redesigns have been commonplace as book collections make way for computer stations and study spaces. in all these cases, adjustments and updates will be necessary to keep a subject map accurate. this is easily done by going back into the master .fla file and editing as needed. in many cases only a stack or two need be adjusted, but in instances of major collection shifting some planning ahead may be necessary and more time allotted for redesign. shifting can be a complex spatial exercise and it is difficult to predict where subjects will realign exactly. subject map editing may have to wait until physical shifting is completed. it should be noted that each stack must be hand-coded separately. in libraries with hundreds of stacks this can seem a tedious and time-consuming design method. both subject maps rely on adobe flash animation technology. flash is proprietary software, so the benefits of open source software cannot be utilized with subject maps at this time. further, abobe flash reader software must be installed on a computer for the subject map to render. this has almost never been a problem, however, as the flash reader is ubiquitous and automatically installed on most public and private machines upon initial boot up. another concern, however, relating to flash technology is human assets. not every library has a flash designer or even someone who can implement the most fundamental flash capabilities. flash is not hard to learn and the subject maps utilize only its most basic functionalities, but still, for some it remains a niche software and many libraries will not have the resources to invest. reaction, though, to the live subject maps and the rollover interactivity they provide, has been so positive that more fully integrated flash maps have been proposed. why not have all physical elements of the library incorporated into one flash-enabled map? this is possible but may come at some expense to the functionality of the subject-rendering aspect of the maps. by limiting the application to stacks and lc classes, a user may remain more focused. avoiding clutter, overcrowding, and a preponderance of choice is a design strategy that has gained much credibility in recent years.3 the subject map enjoys the usability success of clean design, limited purpose, and simple rendering. while demonstrating the potential of user-activated animation for other proposed library applications, the subject map might be best maintained as a limited specialty map. a final concern regarding the long-term success of subject maps should be mentioned. how long will books remain in libraries? how long will they be organized by subject? when the physical animated subject maps for book collections | donahue 14 arrangement and organization of information objects no longer exists in libraries, maps of any kind will seemingly lose all efficacy. but will libraries themselves exist in this future? whither books? whither libraries? future developments the most prominent and practical attribute of the subject map is its ability to show a user the exact stack where the book they are seeking is located. but in its current state as a stand-alone application, a user must obtain a call number from a catalog search, then open the subject map by going to its independent url. investigation is underway to determine what is necessary in order to integrate the subject map with the online catalog. in this scenario, a catalog item record might also display an embedded subject map that automatically highlights the floor and stack where the call number is located. this seemingly requires .swf files and flash actionscript to be embedded in catalog coding. one potential solution is to attribute an individual url to each stack rendering so that a get url function can be applied and embedded in each catalog item record. this synthesis of subject map and catalog poses a complex challenge but promises meaningful and time-saving results for the item retrieval process. qr code technology in conjunction with subject map use is also being deployed. by fixing qr codes on stack end cards that link to relevant sections of the lc outline, a researcher may use a mobile device to browse digitally and physically within the stacks at the same time. in this way a user may conduct digital subject browsing and physical item browsing simultaneously. the urls linked to by qr coding contain detailed lc sub-levels not contained within the subject map, which is limited to the level of sub-class. the active discovery of new knowledge facilitated by exploiting preexisting lc organization inside library stacks in real time can be quite impressive when experienced firsthand. another development exploiting lc knowledge organization is in beta mode at this time. an lc search database has been created allowing users to enter words and find matching lc subject terminology. potentially, this database could be merged with the subject map, allowing users to correlate subject word search with physical locations independent of call numbers. despite its intent as a limited specialty map, possibilities are also being explored to incorporate the subject map into a more fully integrated library map. one way forward in this regard is to create map layers that could be toggled on and off by users. in this way, the subject map could exist as its own layer, maintaining its clarity and integrity when isolated but integrated when viewed with other layers. flash technology excels at allowing such layer creation. other stack maps and related technologies searching the web for “subject map” and relative terminology such as stack, shelf, book, and lc maps, does turn up various efforts and approaches to organizing and exploiting classification scheme data, but no animated, user-activated maps are found. similar searches across library and information science literature turn up some explorative research on the possibilities of mapping information technology and libraries | june 2013 15 lc data, but again no animated stack maps are found.4 there is a product licensed by bowker inc. called stackmap that can be linked to catalog search results. when a user clicks on the map link next to a call number result, a map is displayed with the destination stack highlighted, but the information provided is locational only. stackmap is not animated or user-activated. no subject information is given and the map offers no browsing features. since the release of html5, we are beginning to see more animation on the web that is not flashdriven. steve jobs and apple’s determined refusal to run flash on their mobile devices has motivated many to seek other animation options. new html5 animation tools such as adobe edge, hippo animator, and hype offer promising starts at dislodging the flash grip on web animation, but they have far to go and do not yet offer either the ease of design nor the range of creative possibilities of flash. building an animated subject map with html5 alone does not seem possible at this time. universal applicability of the subject map so far, subject maps have been created for two very different libraries. the commonality shared between the montana state university and skidmore college libraries is their possession of hundreds of thousands of books in stacks shelved by the lc classification system. this is a trait shared by nearly all college and research libraries. subject maps can be easily structured on the dewey decimal system as well so that public libraries could benefit from their functionality, making the subject map appropriate and creatable for more than 12,000 libraries.5 of our two primary textual formats, articles by far have received the most fiscal and technological support in recent decades. article searching and retrieval continues to evolve through the rich implementation of assets such as locally constructed resource management tools, independent journal title searches, complexly designed database search interfaces, and dedicated electronic resource librarians. meanwhile, our more traditional format, the book, seems in some ways to already be treated as a languishing symbol of the past. because its future is uncertain, does that justify our neglect in the present? as a profession we seem a bit complacent about the state of our book collections. why dedicate our technical resources to a format that is on the way out? but has the book disappeared yet? as we make room for more student lounges, coffee bars, computer stations, writing labs, and information commons, we should carefully ask what makes a library special. good books and the focused, sustained treatment of knowledge they contain are part of the correct answer, symbolically and as yet, practically speaking. while our books still occupy our library shelves, shouldn’t they also fully benefit from the ongoing technological explosion through which we continue to evolve? opacs haven’t evolved much in recent years. in fact they seem quite stymied to many librarians and users. we can do more with current technologies to assist and enrich the experience of users searching and browsing for books. the subject map is hopefully an example of how we can do more in this regard. while we have grown accustomed to increasingly look forward in order to position our libraries for the future, we should also remember to sometimes look back. our classification systems and animated subject maps for book collections | donahue 16 book collections are assets built from the past that represent many decades of great labor, investment, and achievement. more than 12,000 public and academic libraries together make up one of our greatest national treasures and bulwarks of living democracy. libraries are among the dearest valued assets in any of our states. many of the most beautiful buildings in our nation are libraries. based on library insurance values and estimated replacement costs, library buildings and the collections they hold amount cumulatively to hundreds of billions of dollars of worth.6 this astounding worth is figured mainly from the buildings themselves and the books they contain. a few have commented that there is some aesthetic quality to the subject maps. if this is true, the appeal comes from the synthesis of architectural form and the universe of knowledge revealed within, from the beauty of libraries both real and ideal, from physical and mental constructions unified. animated subject maps can help bring the physical and intellectual beauty of libraries into the digital realm, but the main appeal is a practical one: to point the user directly to the book or subject they are seeking. so in conclusion, perhaps we should measure the subject map’s potential in the light of ranganathan’s five laws of library science:7 1. books are for use. 2. every reader his [or her] book. 3. every book its reader. 4. save the time of the reader. 5. the library is a growing organism. the subject maps can be found at the following urls: skidmore college

virtue of the systems we select or develop and implement. people working in most facets of library operations trust and rely on our hardware and software to accomplish their daily work, for which we bear a significant burden of responsibility. are they using the best possible tools for their work? are they using them in the best way? a great deal of effort has gone into user-centered design and improving functionality for our patrons, but in this time of reduced budgets and changing staff roles, it is important to extend similar consideration to the systems that we provision for our co-workers. at its best, information technology has the ability to save time and add value to the library by creating efficiencies and empowering people to do better and new work. whether we are evaluating new integrated library systems or choosing the default text editor for our workstations, we are presented with opportunities to learn more about how our libraries accomplish work “on the ground” and reconsider the role that technology can play in helping them. the phrase “eating your own dog food” is so common in software development circles that some have begun using it as a verb. developers engage in “dogfooding” by using new software themselves, internally, to identify bugs and improve usability and functionality before releasing it to users. this is a regular practice of companies such as microsoft1 and google2. setting aside any negative connotations for the moment (why are people eating dog food? and exactly who are the “dogs” in this scenario?), there is a lot that we can learn by putting ourselves in the place of our users and experiencing our systems from their perspective. perhaps the best way to do this is to walk around the building and spend time in each unit of the library, shadowing its staff and observing how they interact with systems to do their work. try to learn their workflow and observe the tasks they perform—both online and offline. you don’t need to become an expert, but ideally you’d be able to try to perform some of the tasks yourself. in one case, we were able to identify and enable someone to design and run their own reports, which helped their unit make more timely decisions and eliminated the need for it to run monthly reports on their behalf. if these tasks support user-facing interactions, you might get some good usability information in the process too. for example, i learned more about our library’s website by working chat reference for an hour a week than i did in two years of web development team meetings! part of this process is attempting to feel our users’ pain, too. do you use the same locked-down workstation image that you deploy to your staff desktops? there is also a tendency among it staff to keep the newest and best machines for their own use and cycle older machines to other units. i understand—it staff are working with databases and doing developing software, and so we benefit the most from higher-performing machines—but keep in mind that your co-workers likely have older, slower machines and take the lowest common denominator hardware into account when selecting new software. by walking a mile in your users’ shows, you may gain a deeper appreciation and understanding of the other units of the library and how they work together. because so much work is done on computers, people working in information technology can often see a broad picture of the activities of the library. we have the ability to make connections and identify potential points of integration, not only between machines but also between people and their work. references 1. pascal g. zachary, showstopper! the breakneck race to create windows nt and the next generation at microsoft (new york: free

| september 2012 24 abstract the use of the metadata encoding and transmission standard (mets) schema as a mechanism for delivering a digital library of complex scientific multimedia is examined as an alternative to the fedora content model (fcm). using mets as an “intermediary” schema, where it functions as a template that is populated with content metadata on the fly using extensible stylesheet language transformations (xslt), it is possible to replicate the flexibility of structure and granularity of fcm while avoiding its complexity and often substantial demands on developers. mets as an intermediary schema for a digital library of complex scientific multimedia of the many possible approaches to structuring complex data for delivery via the web, two divergent philosophies appear to predominate. one, exemplified by such standards as the metadata encoding and transmission standard (mets)1 or the digital item declaration language (didl),2 relies on the structured packaging of the multiple components of a complex object within “top-down” hierarchies. the second, of which the fedora content model (fcm) is perhaps a prime example,3 takes the opposite approach of disaggregating structural units into atomistic objects, which can then be recombined according to the requirements of a given application.4 neither is absolute in its approach—mets, for instance, allows cross-hierarchy linkages, and many fcm models are designed hierarchically—but the distinction is clear. many advantages are validly claimed for the fcm approach to structuring digital data objects. individual components, not constrained to hierarchies, may be readily reused in multiple representations with great flexibility.5 complex interobject relationships may be encoded using semantic linkages,6 a potentially much richer approach to expressing these than the structural relationships of xml can allow. multiple levels of granularity, from that of the collection as a whole down to its lowest-level components, can readily be modelled, allowing interobject relationships to be encoded as easily as intercomponent ones.7 such models, particularly the rdf-based fedora content model, are very powerful and flexible, but can often lead to complexity and consequently considerable demands on system development before they can be implemented. in addition, despite the theoretical interoperability offered by rdf, in practice the exchange and reuse of content models has proved somewhat limited because considerable work is usually required to re-create and validate a content model created elsewhere.8 this article examines whether it is possible to replicate the advantages of this approach to structuring data within the constraints of the more rigid mets standard. the data used for this analysis is a set of digital objects that result from biological nanoimaging experiments, the interrelationships of which present complex problems when they are delivered online. the richard gartner (richard.gartner@kcl.ac.uk) is a lecturer in library and information science, king’s college, london. mets as an intermediary schema for a digital library of scientific multimedia | gartner 25 method used is an unconventional use of a mets template as an intermediary schema;9 this allows something of the flexibility of the fcm approach while retaining the relative simplicity of the more structured mets model. a nanoimaging digital library and its metadata requirements the collection analysed for this study derives from biological nanoimaging experiments undertaken at the randall division of cell and molecular biophysics at king’s college london. biological nanoimaging is a relatively new field of research that aims to unravel the biological processes at work when molecules interact in living cells; this is done by using optical techniques that can resolve images down to the molecular level. it has particular value in the study of how diseases progress and has great potential to help predict the effects of drugs on the physiology of human organs. as part of the biophysical repositories in the lab (bril) project at king’s college london,10 a digital library is being produced to meet the needs of practitioners of live cell protein studies. although the material being made available here is highly specialised, and the user base is restricted to a specialist cohort of biologists, the challenges of this library are similar to those of any collection of digital objects: in particular, the metadata strategy employed must be able to handle the delivery of complex, multifile objects as efficiently as, for example, a library of digitized books has to manage the multiplicity of image files that make up a single digital volume. the digital library itself is hosted on the widely used fedora repository platform; as a result, it is employing fcm as the basis of its data modelling. the purpose of this analysis is to ascertain whether mets can also be used for the complex models required by this data and to compare its potential viability as an architecture for this type of application with fcm. a particular challenge of this collection is that the raw images from which it is constituted require combining and processing before they are delivered to the user. a further challenge is that the library encompasses images from a variety of experiments, all of which combine these files in different ways and employ different software for processing them. some measure of the complexity of these requirements can be gathered from figure 1 below, which illustrates the processes involved in delivering the digital objects for two types of experiments. figure 1. architecture for two experiment types mets as an intermediary schema for a digital library of scientific multimedia | gartner 26 the images created by two experiments, bleach and actin_5, are shown here: it will be seen that the bleach experiment is divided into two subtypes (here called 2grating and apotone). each type or subtype of experiment has its own requirements for combining the images it produces before they are displayed. for the subtype 2grating, for instance, two images, each generated using a different camera grating, are processed in parallel (indicated by the brackets); these are then combined using the software package process-non-clem (shown by the hexagonal symbol) to produce a display image in tiff format. the subtype apotone requires three grating images and a further image with background information to be processed in parallel by the software process-apotone; in this case, the background image provides data to be subtracted from the combined three grating images to produce the final tiff for display. actin_5 experiments are entirely different: they produce still images that need to be processed sequentially (shown by the braces) to produce a video. encoding the bril architecture in mets this architecture, although complex, is readily handled within mets in a manner analogous to that of more conventional collections. as in any mets file, the structure of the experiments, including their subexperiments, is encoded using nested division (<div>) elements in the structural map (example 1a). <div type= “experiment-types”> <div type= “experiment-bleach” id= “experiment-type0001”> <div type= “experiment-bleach-2grating” id= “experiment-type0001-subtype001”> [subsidiary <div>s containing image information] </div> <div type= “experiment-bleach-apotone” id= “experiment-type0001-subtype002”> [subsidiary <div>s containing image information] </div> </div> <div type= “experiment-actin_5” id= “experiment-type0002”> [subsidiary <div>s containing image information] </div> </div> example 1a. sample experiment-level structural map within these containing divisions, subsidiary <div> elements are used to map the combination of images necessary to deliver the content for each type. mets allows the specification of the parallel or sequential structuring of files using its <par> and <seq> elements respectively. the parallel processing of the apotone subtype, for instance, could be encoded as shown in example 1b. information technology and libraries | september 2012 27 <div type= “experiment-bleach-apotone-images” id= “apotone-000”> <fptr> <par> <area fileid= “apotone-grating1–000”/> <area fileid= “apotone-grating2–000”/> <area fileid= “apotone-grating3–000”/> </par> </fptr> </div> example 1b. sample parallel structure for raw image files to be combined using a process specified in associated metadata (behavior section) each division of the structural map of this type may in its turn be attached to a specific software item in the mets behavior section to designate the application through which it should be processed: the tri-partite set of images in example 1b, for instance, would be linked to the processapotone software using the code in example 1c. <behavior groupid= “process-apotone” structid= “apotone-000”> <mechanism loctype= “url” ns2:href= “software/process-apotone”/> </behavior> example 1c. sample mets behavior mechanism for a specification of image processing this approach is straightforward, and mets is capable of encoding all of the requirements of this data model, although at the cost of large file sizes and a degree of inflexibility. this may be no problem when the principle rationale behind the creation of this metadata is preservation: linking all of the project metadata in a coherent, albeit monolithic, structure of this kind benefits especially its usage as an open archival information system (oais) archival information package (aip), one of the key functions for which mets was designed. problems are likely to arise, however, when this approach is scaled up in a delivery system to include the potentially millions of data objects that this project may produce. the large size of the mets files that this approach necessitates makes their on-the-fly processing for delivery much slower than a system that uses aggregations of the smaller files required by the fcm model and so processes only metadata at the granularity necessary for the delivery of each object. such flexibility is much harder to achieve within mets, although mechanisms that currently exist for aggregating diverse objects within mets may seem to offer some degree of solution to this problem. complex relationships under mets underlying the mets structural map is an assumed ontology of digital objects that encodes a longestablished view of text as an ordered hierarchy of content objects;11 this model accounts for the mets as an intermediary schema for a digital library of scientific multimedia | gartner 28 map’s use of hierarchical nesting and the ordinality of the object’s components. the rigidity of this model is alleviated to some extent by the facility within mets to encode structural links that cut across these hierarchies. these links, which join nodes at any level of the structural map, are particularly useful for encoding hyperlinks within webpages,12 and so are often used for archiving websites. various attempts have been made to extend the functionality of the structural map and structural links sections to allow more sophisticated aggregations and combinations of components beyond the boundaries of a single digital object, in a manner analogous to the flexible granularity of fcm. mets itself offers the possibility of aggregating other mets files through its <mptr> (mets pointer) element: this element, always a direct child of a <div> element in the structural map, references a mets file that contains metadata on the digital content represented by this <div>. for example, two complex digital objects could be represented at a higher collection level, as shown in example 2. <div> <div id= “bleach2grating-1”> <mptr loctype= “url” xlink:href= “twogratingbleach6-grating1–01.xml”/> </div> <div id= “bleach2grating-2”> <mptr loctype= “url” xlink:href= “twogratingbleach6-grating1–02.xml”/> </div> </div> example 2. use of mets <mptr> element this feature has found some use in such projects as the echo depository, which uses it to register digital objects at various stages of their ingest into, and dissemination from, a repository;13 it is also recommended by the paradigm project as a method for archiving born-digital content, such as emails.14 nonetheless, its usage remains fairly limited; of all the mets profiles registered on the central mets repository, for instance, echo dep at the time of writing remains the only project on the library of congress’s repository of mets profiles to employ this feature. 15 an important reason for its limited take-up is that its potential for more sophisticated uses than merely populating a division of the structural map is severely limited by its place in the mets schema. the <mptr> element can only be used as a direct child of its parent <div>: it cannot, for instance, be located in <par> or <seq> elements to indicate that the objects referenced in its subordinate mets files should be processed in parallel or in sequence (as is required by the different experiment types in figure 1), nor may the contents of these files be processed by the sophisticated partitioning features of the <area> element, which allows subsidiary parts of a <div> to be addressed directly. a more sophisticated approach to combining digital object components is to employ open archives initiative object reuse and exchange (oai-ore) aggregations,16 which express more complex relationships at greater levels of granularity than the <mptr> method allows. information technology and libraries | september 2012 29 mcdonough’s examination of the possibility of aligning the two standards concludes that it is indeed possible, although at the cost of eliminating the mets behavior section and removing much of the flexibility of mets’s structural links, both side effects of oai-ore’s requirement that resource maps must form a connected rdf graph.17 in addition, converting between mets and oai-ore may not be lossless, depending on the design of the mets document.18 neither approach therefore seems ideal for an application of this type, the former because of the limited ways in which the <mptr> element can be deployed outside the <area> element and its subsidiaries, the latter because of its removal of the functionality of the behavior section, which is essential for the delivery of material such as this. mets as an intermediary schema an alternative approach adopted here uses the technique of employing mets files as intermediary schemas to act as templates from which mets-encoded packages for delivery can be generated. intermediary xml schemas are intermediary in the sense that they are designed not to act as final metadata containers for archiving or delivery, but as mediating encoding mechanisms from which data or metadata in these final forms can be generated by xslt transformations: one example is cerif4ref, a heavily constrained xml schema used to encode research management information from which metadata in the complex common european research information format (cerif) data model can be generated.19 the cerif4ref schema attempts to emulate the architectural processing features of sgml,20 which are absent from xml; these allowed simpler document type definitions (dtds) to be compiled for specific applications, which could then be mapped to established, more complex, sgml models. instead of architectural processing, cerif4ref uses xslt to carry out this processing, so allowing the combination of a simpler scheme tailored to the requirements of an application to be combined with the benefits of a more interoperable but highly complex model that is difficult to implement in its standard form. instead of using this technique for constraining encoding to a simpler model and generating more complex data structures from this, the intermediary schema technique may be used to define templates, similar to a content model, from which the final mets files to be delivered can be constructed. as is the case with cerif4ref, xslt is used for these transformations, and the xslt files form an integral part of the application. in this way, a series of templates, beginning with highest-level abstractions, are used to generate their more concrete subsidiaries, until a final version used for dissemination is generated. the core of this application is a mets file, which acts as a template for the data delivery requirements for each type of experiment. figure 2 demonstrates the components necessary for defining these for the 2grating experiment subtype detailed previously in figure 1. mets as an intermediary schema for a digital library of scientific multimedia | gartner 30 figure 2. defining an experiment subtype in mets the data model for the delivery of these objects is defined in the <structmap> (b): as can be seen here, a series of nested <div> elements is used to define the relationship of experiment subtypes to types, and then to define, at the lowest level of this structure, the model for delivering the objects themselves. in this example, two files are to be processed in parallel; these are defined by <area> elements within the <par> (parallel) element. in a standard mets file, the fileid attribute of <area> would reference a <file> element within the mets file section (a): in this case, however, they reference empty file group (<filegrp>) elements, which are populated with <file> elements when this template undergoes its xslt transformation. the final component of this template is the mets behavior section (c), in which the applications required to process the digital objects are defined. two behavior sections are shown in this example: the first is used to invoke the xslt transformation by which this mets template file is to be processed, the second to define the software necessary to co-process the two images files for delivery. both indicate the divisions of the structural map whose components they process by their structid attributes: the first references the map as a whole because it applies to recursively to the mets file itself, the second references the experiment for which it is needed. when delivering a digital object, it is then necessary to process this template mets file to generate the final version used to encode its metadata in full. the xslt used to do this co-processes the template and a separate mets file defined for each object containing all of its relevant metadata: information technology and libraries | september 2012 31 this latter file is used to populate the empty sections of the template, in particular the file section. figure 3 provides an illustration of the xslt fragment which carries out this function. figure 3. the xslt transformation file is evoked with the sample parameter, which contains the number of the sample to be rendered: this is used to generate the filename for the document function, which selects the relevant mets file containing metadata for the image itself. the <file> element within this file, which corresponds to the required image, is then integrated into the relevant <filegrp> element in the template file, populating it with its subcomponents, including the <flocat> element, which contains the location of the file itself. in the case of the actin_5 experiment, which generates a video file from a sequence of still images, the processes involved are slightly more complicated. because the number of still images to be processed will vary for each sample, it is not possible to specify the template for the delivery mets as an intermediary schema for a digital library of scientific multimedia | gartner 32 version of the sequence explicitly within a <filegrp> element as is done for the other experiments. instead, it is necessary to define a further mets file (the “sequence file”) in which the sequence for a given sample is defined. in this case, the architecture is shown in figure 4. figure 4. populating sequentially processed file section with xslt in this case the <filegrp> element in the mets template file acts as a placeholder only and does not encode even the skeletal information for the parallel-processed tiff files in figure 3. similarly, the structural map <div> for this experiment indicates only that this section is a sequence but does not enumerate the files themselves even in template form. both of these sections are populated when the file is processed by the xslt transformation to import metadata from the mets “sequence file,” information technology and libraries | september 2012 33 in which the file inventory (a) and sequential structure (b) for a given sample are listed. the xslt file populates the file section and structural map directly from this file, replacing the skeletal sections in the template with their counterparts from the sequence file. through this relatively simple xslt transformation, the final delivery version of the mets file is readily generated for either content model. this file can itself then be delivered on the fly (for instance, as a fedora disseminator); this is done by using a further xslt file to process the complex digital object components using the mechanism associated with each experiment in the mets behavior section. given the relatively small size of all of the files involved, this processing can be done more quickly than would be possibly using a fully aggregated mets approach. in the laboratory environment in particular, where the fast rendering and delivery of these images is needed so as not to impede workflows, this has major advantages. although the project aimed to examine specifically the use of fedora for the delivery of this complex material, and so employed fcm as the basis of its metadata strategy, the technique examined in this article proved itself a viable alternative that made much fewer demands on developer time. the small number of xslt stylesheets required to render and deliver the mets files were written within a few hours: the development time to program the delivery of the rdfbased metadata that formed the fcm required several weeks. processing xml using xslt disseminators in fedora is very fast, and so using this method instead of processing rdf introduces no discernible delays in object delivery. conclusions this approach to delivering complex content appears to offer the benefits of the alternative approaches outlined above in a simpler manner than either currently allows. it offers much greater flexibility than the mets <mptr> element, which can only populate a complete structural map division. when compared to the fcm approach, this strategy, which relies solely on relatively simple xslt transformations for processing the metadata, requires less developer time but offers a similar degree of flexibility of structure and granularity. it also avoids much of the rigidity of the oai-ore approach by not requiring the use of connected rdf graphs, and so frees up the behavior section to define the processing mechanisms needed to deliver these objects. using the intermediary schema technique in this way does therefore offers a means of combining the advantages of employing well-defined interoperable metadata schemes and the practicalities of delivering digital content in an efficient manner, which makes limited demands on development. as such, it represents a viable alternative to the previous attempts to handle complex aggregations within mets discussed above. the adoption of integrated library systems (ils) became prevalent in the 1980s and 1990s as libraries began or continued to automate their processes. these systems enabled library staff to work, in many cases, more efficiently than they had been in the past. however, these systems were also restrictive—especially as the nature of the work began to change—largely in response to the growth of electronic and digital resources for which they were not intended to manage. new library systems—the second (or next) generation—are needed to effectively manage the processes of acquiring, describing, and making available all library resources. this article examines the state of library systems today and describes the features needed in a next-generation ils. the authors also examine some of the next-generation ilss currently in development that purport to fill the changing needs of libraries. mets as an intermediary schema for a digital library of scientific multimedia | gartner 34 references 1 library of congress, “metadata encoding and

technology and libraries | march 2022 https://doi.org/10.6017/ital.v41i1.13659 dominic byrd-mcdevitt (dominic@dp.la) is data fellow, digital public library of america. john dewees (john.dewees@toledolibrary.org) is supervisor, digitization services, toledo lucas county public library. © 2022. abstract the digital public library of america has created a process by which rights-free or openly licensed resources that have already been harvested can be copied over into wikimedia commons, thus creating a simple path for including those digital collections materials into wikipedia articles. by meeting internet users where they already are, rather than relying on them to navigate to individual digital libraries, the access and usage of digital assets is dramatically increased, in particular to user groups that might otherwise not have a reason to interact with such digitized resources. introduction a dpla-sponsored webinar given by dominic byrd-mcdevitt, dpla data fellow, and sandra fauconnier, glam-wiki specialist at the wikimedia foundation, on april 21, 2020, entitled “dpla intro to wikimedia: increased discoverability and use” introduced a workflow by which records harvested by the digital public library of america (dpla) could be automatically copied over into wikimedia commons with their accompanying metadata.1 the major benefit of this migration is the ease with which assets can then be added to wikipedia articles, exposing resources to a large audience of general internet users who might otherwise have no reason to interact with a given repository’s resources. the gains from making digitized resources available in wikipedia articles is substantial, providing incredibly high usage statistics while requiring very little time commitment to execute the work. this dpla project, launched in early 2020, was a result of grant funding provided by the alfred p. sloan foundation and ongoing consultation from the wikimedia foundation. dpla’s interest in designing this system stemmed from an exploration of new ways to increase usage of materials. while previous bulk uploads to wikimedia commons by cultural institutions have required technical expertise and steep learning curves in navigating the wikimedia community, this project was designed to reduce these barriers by taking advantage of dpla’s role as an aggregator (more information is available at https://commons.wikimedia.org/wiki/commons:partnerships). with the workflow developed by dpla’s technology team in mid-2020, an authorized bot account on wikimedia commons (user:dpla_bot, https://commons.wikimedia.org/wiki/user:dpla_bot) uploads assets from dpla institutions. using data provided by contributing institutions, dpla applies filters to identify eligible items from participating institutions, then for each of these generates wiki markup from descriptive metadata and downloads media files to a server. these files are uploaded by a script that interacts with wikimedia’s api using the pywikibot framework (https://www.mediawiki.org/wiki/manual:pywikibot). by centralizing all of the dpla network’s wikimedia commons uploads, dpla was able to upload over 2.25 million files (or 2.5 tb of total mailto:dominic@dp.la mailto:john.dewees@toledolibrary.org https://commons.wikimedia.org/wiki/commons:partnerships https://commons.wikimedia.org/wiki/user:dpla_bot https://www.mediawiki.org/wiki/manual:pywikibot information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 2 storage) from 780,000 items in under a year and a half, becoming the largest single contribution to wikimedia commons ever (by more than quadruple the previous record). 2,3 this approach to the problem provides a simple on-ramp to participation in wikipedia for dpla institutions—especially the many that would otherwise lack the resources or expertise to do so— by requiring of them only those tasks that need their local knowledge, such as describing their own collections prior to aggregation and then making editorial decisions on wikipedia about them once uploaded. this project required a chain of partnerships between separate organizations, as well as a variety of metadata and technical requirements that needed to be satisfied: records of digitized resources are created by an organization locally and are then harvested by dpla. the eligible records in dpla are then copied over into wikimedia commons. once images are in wikimedia commons it is a straightforward process to embed the images in wikipedia articles, thus achieving the goal of expanded use and access to digitized resources. john dewees, supervisor digitization services at the toledo lucas county public library (tlcpl), was in attendance at the april 21, 2020 webinar and subsequently met with dominic byrd mcdevitt on april 30, 2020 to discuss the feasibility of using tlcpl collections as a pilot project for this workflow. the copying of records from tlcpl’s repository into wikimedia commons was actually started in the course of that first conversation on april 30. a map from page 96 of the book geography of ohio (see figures 1 and 2), previously digitized by dewees, will be used to illustrate the process of how records move through the various tools and platforms discussed.4 tlcpl makes digitized resources available through ohio memory, a shared contentdm instance for libraries, archives, and museums in ohio maintained by the state library of ohio and the ohio history connection.

information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 5 dpla harvest dpla is a discovery portal that aggregates records of digitized resources from over 4,000 libraries, archives, and museums from around the united states. this creates a single search interface allowing millions of digital records to be searched simultaneously without having to navigate through a wide variety of different digital libraries. the aggregation of these records is accomplished by working with two different types of partners: content hubs and service hubs.5 content hubs are either organizations large enough to contribute to dpla directly, such as the library of congress or harvard library, or large digital libraries that work with partner institutions of their own, such as hathitrust or the internet archive. service hubs, on the other hand, act as mediators between the national aggregation service and individual organizations in states (such as ohio and its service hub, the ohio digital network) or regions (such as utah, idaho, and nevada, who have collectively formed a service hub in the mountain west digital library). service hubs ensure that the technical and metadata requirements for harvesting into dpla are satisfied and act as consultants and facilitators to prospective contributors. as dpla has grown over time, the metadata requirements and possibilities have also evolved and have varied depending on which service hub a contributing organization is working with. the ohio digital network (odn) is the service hub for our example page from ohio memory. odn’s metadata requirements for contributors in march 2021 included a title and a standardized rights statement in the metadata application profile for the contributing collection. more information on the dpla harvest process for the ohio digital network is available at https://ohiodigitalnetwork.org/contributors/getting-started. the nature of these requirements has also evolved since odn’s first harvest in march 2018. initially, the standardized rights statement was required to be one of the options from rightsstatements.org but through the work of dpla and odn, now creative commons licenses and the cc0 public domain dedication can be utilized as well. standardized rights statements must be formatted as machine-readable uris rather than textual descriptions. finally, the technical backend that supports the harvest of a digital collection is via an oai-pmh feed. other hubs operate in very different ways—such as some that actually host all their contributors’ collections in a single domain—but in all cases the end result is providing a data set that dpla can harvest and ingest. figures 3 and 4 illustrate this process, showing the geography of ohio represented as a record in dpla (available at https://dp.la/item/aaba7b3295ff6973b6fd1e23e33cde14) with associated metadata.

technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 7 figure 4. geography of ohio as seen in dpla, specifically focusing on the remaining metadata fields harvested. this process achieves the first level of aggregation: harvesting thumbnail images (full-sized images suitable for research are not harvested in this process) and metadata from local digital repositories and making them available for a unified search experience in dpla. dpla’s aggregation currently contains over 42 million items, with the majority of these containing standardized rights uris; 18 million items have rights compatible with upload to wikimedia commons (as can be seen at https://dp.la/search?rightscategory=%22unlimited%20reuse%22). once dpla has access to the records, it is possible for the code authored by dpla staff to be utilized to then integrate the resources into wikimedia commons. wikimedia commons harvest wikimedia commons is part of the larger network of services and tools under the umbrella of the wikimedia foundation. there are a wide variety of different tools available such as wikidata, a portal for open structured data; wikipedia, a collaboratively edited open encyclopedia; and https://dp.la/search?rightscategory=%22unlimited%20re-use%22 https://dp.la/search?rightscategory=%22unlimited%20re-use%22 information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 8 wikimedia commons. this last portal uses the same software platform that powers wikipedia to create an open file and media server that can interoperate with the other tools. wikimedia commons is capable of hosting digital still images, audio files, and video files. anyone can contribute to this open repository so long as the work is in the public domain or openly licensed. users may either release a work for which they own the rights under an open license at upload time or may upload any other works by providing evidence in the metadata that the work is out of copyright or openly licensed (more information on copyright and licensing in wikimedia commons is available at https://commons.wikimedia.org/wiki/commons:licensing). with this in mind, in order for records in dpla to be eligible for harvest into wikimedia commons, they first must have one of the five specific standardized rights statements available at the following links:6 • http://rightsstatements.org/vocab/noc-us/1.0/ • https://creativecommons.org/publicdomain/zero/1.0/ • https://creativecommons.org/publicdomain/mark/1.0/ • https://creativecommons.org/licenses/by/4.0/ • https://creativecommons.org/licenses/by-sa/4.0/ the uris above indicate the most recent version of each of the associated copyright descriptions or licenses, though being published under the most recent version is not a requirement for harvest into wikimedia commons. while standardized rights statements are not a requirement for contributing to dpla generally, they are being used as a requirement for wikimedia commons upload so that the software has a machine-readable way to determine the compatibility of rights. though it is a non-profit educational resource, wikimedia commons does not utilize media under fair use or materials only licensed for noncommercial/educational use, in order to ensure its users may reuse the media for any purpose. as a result one thing to keep in mind is that while a given organization may include in their gift or accession agreement a statement that digitized versions of physical resources are allowed to be shared through channels decided by the organization, this does not necessarily extend to wikimedia commons users outside your organization, because of the requirement to be able to reuse materials with little restriction past attribution and the need to share alike, depending on the standardized rights statement. dpla locates the asset to upload by using urls explicitly provided by the service hub; the urls can be provided in one of two ways. one is to provide the iiif manifest url (via the iiif presentation api), from which the dpla-developed software queries the manifest for the list of assets which are listed by the presentation api in the form of iiif image api urls. the other way the media location can be identified is by providing a list of direct urls to the media in the field dpla calls mediamaster during the initial harvest process. unlike the iiif manifest url, this is a multivalued field that can accommodate a list of urls. the reason for this approach is to allow any institution to contribute assets via the pipeline, regardless of whether they actually have implemented iiif in their repository or not. not all organizations have adopted the iiif suite of apis so it is important to be able to provide more than one avenue for wikimedia commons harvest. https://commons.wikimedia.org/wiki/commons:licensing

2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 9 however, providing a iiif manifest when and if it becomes available has benefits over the mediamaster field. it will always be true when queried, whereas the mediamaster values are only accurate to the last harvest, which may be a month or more out of date. figure 5. the dashboard developed by dpla displaying, for pine river library, percent of records that have open rights statements and percent of files with media access. a dashboard has been developed for dpla content hub and service hub administrators to analyze how many records in a given collection conform to the standardized rights statement and iiif api requirements (see figure 5). harvest of a collection into wikimedia commons from dpla necessitates that all eligible records in the collection be harvested into wikimedia commons; it is not possible for a participating institution to hand-curate which of the eligible items will be included. that is, all records in a given collection with the aforementioned standardized rights statements will be harvested into wikimedia commons. an additional signed agreement or memorandum of understanding has not been required between dpla and participating organizations due to the open nature of the works being transferred. since the works have been identified as in the public domain or openly licensed, users can already freely use the resources for any purpose they want, so long as it conforms to the appropriate creative commons license. resource presentation in wikimedia commons each portion of the migration process presents the resource in different ways. the original instance of geography of ohio is made available in contentdm as a complex digital object: multiple images (or more specifically in this case, pages) associated with a single metadata record. dpla presents this resource only in terms of its metadata along with a thumbnail image of the resource itself; to view the contents of the resource the user is directed back to the original repository for full access to the digital object. the migration process into wikimedia commons actually copies the image assets themselves along with the metadata. in this example, both the information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 10 image assets and the metadata are drawn from contentdm. wikimedia commons is not able to accommodate complex digital objects, and any that are imported via this process are broken out into discrete simple digital objects in wikimedia commons, for example, page 96 of geography of ohio (see figures 6, 7, and 8; view page 96 in wikimedia commons). figure 6. geography of ohio, page 96, as seen in wikimedia commons, with a focus on the

dpla and the wikimedia foundation | byrd-mcdevitt and dewees 12 the filename is programmatically generated and embeds a great deal of information; the following example illustrates the various components of the filename. example filename: file:geography of ohio dpla aaba7b3295ff6973b6fd1e23e33cde14 (page 96) (cropped).jpg 1. the prefix for all items in wikimedia commons, “file:” 2. the title of the work, in this case “geography of ohio” followed by a hyphen 3. the source of the digital object, universally “dpla” for this project, followed by a hyphen 4. the unique identifier assigned by dpla, in this case “aaba7b3295ff6973b6fd1e23e33cde14” 5. in the case of complex objects, the page number, in this case “(page 96)” 6. if the file was cropped using wikimedia common’s built-in image editing tool, “(cropped)” will be included between the page number and file extension to indicate the image is a derivative of an original 7. the file format extension, in this case “.jpg” even if the complex object being imported is not actually a book, the individual item records in wikimedia commons still uses the “(page x)” nomenclature to differentiate the individual objects. the summary section of the wikimedia commons record displays how the metadata is crosswalked into this environment. the dublin core creator, title, description and date fields are copied verbatim from the local metadata application profile (map). to identify the contributing institution, and to differentiate between similarly named institutions, dpla maintains a json file mapping all dpla institutions with their wikidata identifiers.7 this document also indicates which hubs/institutions are participating in the project at any given time through a true/false field that is toggled when an institution authorizes upload. this enables distinct category pages for each contributing institution and analytics to be tracked and provided to dpla, relevant hubs, and contributing institutions. the source/photographer field is one of the most important as it ensures that attribution for the contributing institution is clear. the field contains a narrative description of how dpla facilitated this resource to be available in wikimedia commons. it also makes available information on the original contributing institution with links to the record as it is originally displayed (in ohio memory in this case) as well as in dpla. proper attribution of items was a topic that came up continuously when discussing this project with other organizations, so it should be reassuring to know that credit and direct links back to resources is enabled in this workflow. the permission and standardized rights statement fields leverage the aforementioned uris to be able to provide information to the user on the copyright status of the work as well as concrete information on how exactly they are able to use it responsibly for their own purposes. finally, an interesting aspect of this record is the links provided to derivative images. in this case we can see the map displayed on this book page has two cropped derivative images. use in wikipedia articles all of the work described above is in service of one goal: to enable higher usage and exposure of digitized resources in wikipedia articles. while it is possible to do this work manually, inserting images into articles without being a dpla contributor or even having a digital repository to speak information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 13 of, the automated process is a clear advantage, especially when talking about large collections. for the map on page 96 in geography in ohio, we can see that the map of limestone distribution in ohio has been included in an image gallery on the limestone wikipedia article (see figures 9 and 10). figure 9. the wikipedia article on limestone displaying the introduction and one

figure 10. the image gallery in the limestone wikipedia article, with the map from geography of ohio included and seen at the bottom right. figure 11. the source view editing option for the limestone article in wikipedia, allowing direct editing of the wikitext. once images are in wikimedia commons, embedding the images in wikipedia articles is a simple process. one option for wikipedia editors is to use a what you see is what you get (wysiwyg) information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 15 html editor that should be familiar to most users. alternately, there is also a source view editing option which uses the custom markdown called wikitext to format pages in wikipedia (see figure 11). source view editing allows more precision when inserting images into wikipedia articles and makes it easier to understand how they will ultimately be displayed in the article. the way in which different page elements flow around one another in articles can be surprising when using the wysiwyg editing option as images assumed to show up where you placed the cursor can ultimately be placed in very different locations than expected. 8 usage analytics analytics tools are available that allow organizations to track the articles containing their assets, showing what image was embedded in an article and how many views the article received. tlcpl’s initial ingest added a total of 129,725 discrete image assets to wikimedia commons. from that pool, images were added to a total of 227 wikipedia articles between may 2020 and february 2021 (see figure 12). in that time period the articles had a total of 11.7 million page views (see figure 13).9 in february 2021 alone, the 227 enriched articles received 1.87 million page views. by comparison, the total number of records tlcpl had available in ohio memory was 129,395 in february 2021, and those records received 26,602 unique page views. the major strength of this project is to display locally created digitized resources where researchers would already be on the open web and take advantage of that much wider level of exposure.10 figure 12. a graph

one-to-one match, but no matter the measurement it is fairly clear this audience is an order of magnitude beyond what might conventionally be available. ultimately what might be one of the most exciting metrics for an organization looking to implement this work is the amount of time it actually took to execute this project. since tlcpl’s records already satisfied the requirements to be copied over to wikimedia commons, the actual import process was able to begin during the april 30, 2020 zoom call between tlcpl and dpla staff that was set up to discuss the project; from the perspective of the contributing organization, this process takes essentially no time or effort. once the process is started, staff at the contributor institution will be informed when the records have finished being copied. the actual work of locating images for inclusion into articles and inserting them took roughly an hour of work a week, or roughly ten minutes per article, sometimes less. approximately 38 hours of work was spent identifying images and inserting them into articles between may 2020 and february 2021. while not of central concern to the project or its usage, the editorial work is also interesting and uses enough creativity and problem solving to be an enjoyable activity. because the resources in wikimedia commons are available to be used by anyone (as in, anyone with a device and an internet connection), this makes it a wonderful opportunity for interns or volunteers to contribute. volunteers could work on the editorial portion of this project remotely with no real barriers. while all the effort of getting tlcpl digitized images into wikipedia described here has been using previously existing articles, this work could make an excellent partnership opportunity information technology and libraries march 2022 using dpla and the wikimedia foundation | byrd-mcdevitt and dewees 17 with schools to write and create whole new articles for which there is an abundance of already digitized resources to support. conclusion the work of remediating and writing metadata to participate in large consortial efforts such as dpla is always going to be a major undertaking, but projects like this that can leverage automation and partnerships show just how powerful these relationships can be. making locally digitized resources available through dpla, copying them over to wikimedia commons, and then embedding those images into wikipedia articles is an excellent opportunity to meet users where they already are—online. this work provides exceptionally high usage statistics and is fertile ground for outreach and programming opportunities to get partners, volunteers, and interns involved with making those digitized resources available in wikipedia.

 to  protect  their   own  privacy  and  that  of  their  patrons       alexandre  fortier   and     jacquelyn  burkell     information  technology  and  libraries  |  september  2015             59   abstract   librarians  have  a  professional  responsibility  to  protect  the  right  to  access  information  free  from   surveillance.  this  right  is  at  risk  from  a  new  and  increasing  threat:  the  collection  and  use  of  non-­‐ personally  identifying  information  such  as  ip  addresses  through  online  behavioral  tracking.  this   paper  provides  an  overview  of  behavioral  tracking,  identifying  the  risks  and  benefits,  describes  the   mechanisms  used  to  track  this  information,  and  offers  strategies  that  can  be  used  to  identify  and  limit   behavioral  tracking.  we  argue  that  this  knowledge  is  critical  for  librarians  in  two  interconnected   ways.  first,  librarians  should  be  evaluating  recommended  websites  with  respect  to  behavioral   tracking  practices  to  help  protect  patron  privacy;  second,  they  should  be  providing  digital  literacy   education  about  behavioral  tracking  to  empower  patrons  to  protect  their  own  privacy  online.   introduction   privacy  is  important  to  librarians.  the  american  library  association  code  of  ethics  (2008)  states   that  “we  protect  each  library  user’s  right  to  privacy  and  confidentiality  with  respect  to  information   sought  or  received  and  resources  consulted,  borrowed,  acquired  or  transmitted,”  while  the   canadian  library  association  code  of  ethics  (1976)  states  that  members  have  responsibility  to   “protect  the  privacy  and  dignity  of  library  users  and  staff.”  this  translates  to  a  core  professional   commitment:  according  to  the  american  library  association  (2014,  under  “why  libraries?”),   “librarians  feel  a  professional  responsibility  to  protect  the  right  to  search  for  information  free   from  surveillance.”   increasingly,  information  searches  are  conducted  online,  and  as  a  result  librarians  should  be   paying  specific  attention  to  online  surveillance  in  their  efforts  to  satisfy  their  privacy-­‐related   professional  responsibility.  this  is  particularly  important  given  the  current  environment  of   significant  and  increasing  threat  to  privacy  in  the  online  context.  although  many  concerns  about   online  privacy  relate  to  the  collection,  use,  and  sharing  of  personally  identifiable  information,   there  is  increasing  awareness  of  the  risks  associated  with  the  collection  and  use  of  what  has  been   termed  ‘non-­‐personally  identifiable  information’  (e.g.:  internet  protocol  addresses,  pages  visited,   geographic  location  information,  search  strings,  etc.;  office  of  the  privacy  commissioner  of  canada     alexandre  fortier  (afortie@uwo.ca)  is  a  phd  candidate  and  lecturer,  faculty  of  information  and   media  studies,  the  university  of  western  ontario,  london,  ontario.  jacquelyn  burkell   (jburkell@uwo.ca)  is  associate  professor,  faculty  of  information  and  media  studies,  the   university  of  western  ontario,  london,  ontario.     hidden  online  surveillance:  what  librarians  should  know  to  protect  their  own  privacy  and   that  of  their  patrons|  fortier  and  burkell  |  doi:  10.6017/ital.v34i3.5495   60   2011,  12).  this  practice  has  been  termed  ‘behavioral  tracking’,  and  recent  revelations  of   government  security  agency  collection  of  user  metadata  (ball  2013;  weston,  greenwald  and   gallager  2014)  have  heightened  awareness  of  this  issue.  the  problem,  however,  is  not  new,  nor  is   the  practice  restricted  to  the  actions  of  governmental  agencies.  indeed,  as  early  as  1996   commercial  and  non-­‐commercial  entities  were  practicing  online  behavioral  tracking  for  purposes   of  website  and  interaction  personalization  and  to  present  targeted  advertising  (“affinicast  unveils   personalization  tool”  1996;  “adone  classified  network  and  clickover  announce  strategic  alliance”   1997).  since  these  initial  forays  into  behavioral  tracking  and  personalization  of  online  content  the   practice  has  proliferated,  and  many  sites  now  use  a  variety  of  behavioral  tracking  tools  to  enhance   user  experience  and  deliver  targeted  advertisements  (see,  e.g.,  the  “what  they  know”  series  from   the  wall  street  journal  2010;  gomez,  pinnick  and  soltani  2009;  soltani  et  al.  2009).   there  can  be  no  question  that  behavioral  tracking  is  a  form  of  surveillance  (castelluccia  and   narayanan  2012),  and  the  ubiquity  of  this  practice  means  that  users  are  regularly  subject  to  this   type  of  surveillance  when  they  access  online  resources.  in  order  to  satisfy  a  professional   commitment  to  support  information  access  free  from  surveillance,  librarians  must  therefore   address  two  related  issues:  first,  they  must  ensure  that  the  resources  they  recommend  are   privacy-­‐respecting  in  that  those  resources  engage  in  little  if  any  online  surveillance;  second,  they   must  raise  the  digital  literacy  of  their  patrons  with  respect  to  online  privacy,  increasing   understanding  of  online  tracking  mechanisms  and  the  strategies  that  patrons  can  use  to  protect   their  privacy  in  light  of  these  activities.   addressing  the  first  issue  requires  that  librarians  attend  to  surveillance  practices  when   recommending  online  information  resources.  privacy  and  surveillance  issues,  however,  are   notably  absent  from  common  guidelines  for  evaluating  web  resources  (see,  e.g.,  kapoun  1998;   university  of  california,  berkley  2012;  john  hopkins  university  2013),  and  thus  librarians  do  not   have  the  guidance  they  need  to  ensure  that  the  resources  they  recommend  are  privacy-­‐respecting.   it  is  critical  that  librarians  and  other  information  professionals  address  this  gap  by  developing  an   understanding  of  the  surveillance  mechanisms  used  by  websites  and  the  strategies  that  can  be   deployed  to  identify  and  even  nullify  these  mechanisms.  this  same  understanding  is  necessary  to   address  the  second  goal  of  raising  the  privacy-­‐related  digital  literacy  of  patrons.  librarians  must   understand  tracking  mechanisms  and  potential  responses  in  order  to  integrate  privacy  literacy   into  library  digital  literacy  initiatives  that  are  central  to  the  mission  of  libraries  (american  library   association  2013).   this  paper  provides  an  introduction  to  behavioral  tracking  mechanisms  and  responses.  the  goals   of  this  paper  are  to  provide  an  overview  of  the  risks  and  benefits  associated  with  online   behavioral  tracking,  to  discuss  the  various  surveillance  mechanisms  that  are  used  to  track  user   behavior,  and  to  provide  strategies  for  identifying  and  limiting  online  behavioral  tracking.  we   have  elsewhere  published  analyses  of  behavioral  tracking  practices  on  websites  recommended  by   information  professionals  (burkell  and  fortier  2015),  and  on  practices  with  respect  to  the   disclosure  of  tracking  mechanisms  (burkell  and  fortier  2015).  this  paper  serves  as  an  adjunct  to     information  technologies  and  libraries  |  september  2015   61   those  empirical  results,  providing  information  professionals  with  background  that  will  assist  them   in  negotiating,  on  the  part  of  themselves  and  their  patrons,  the  complex  territory  of  online  privacy.   consumer  attitudes  toward  behavioral  tracking   survey  data  suggest  that  consumers  are,  in  general,  aware  of  behavioral  tracking  practices.  the   2013  us  consumer  data  privacy  study  (truste  2013),  for  example,  reveals  that  80  percent  of   users  are  aware  of  online  behavioral  tracking  on  their  desktop  devices,  while  slightly  under  70   percent  are  aware  of  tracking  on  mobile  devices  (see  also  office  of  the  privacy  commissioner  of   canada  2013).  awareness,  however,  does  not  directly  translate  to  understanding,  and  recent  data   indicate  that  even  relatively  sophisticated  internet  users  are  not  fully  informed  about  behavioral   tracking  practices  (mcdonald  and  cranor  2010;  smit  et  al.  2014).  moreover,  attitudes  about   tracking  are  at  best  ambivalent  (ur  et  al.  2012),  and  many  studies  indicate  a  predominantly   negative  reaction  to  these  practices  (turow  et  al.  2009;  mcdonald  and  cranor  2010;  truste   2013).  although  it  is  not  universally  required  by  regulatory  frameworks,  many  users  feel  that   companies  should  request  permission  before  collecting  behavioral  tracking  data  (office  of  the   privacy  commissioner  of  canada  2013).  finally,  although  some  users  take  steps  to  limit  or  even   eliminate  behavioral  tracking,  many  do  not.  for  example,  while  one-­‐third  to  three-­‐quarters  of   survey  respondents  indicate  that  they  manage  or  refuse  browser  cookies  (truste  2013;   comscore  2007;  2011;  rainie  et  al.  2013),  at  least  one  quarter  reported  no  attempts  to  limit   behavioral  tracking.  this  may  be  attributed  to  the  difficulty  in  using  such  mechanisms  (leon  et  al.   2011).   behavioral  tracking  and  its  mechanisms   tracking  mechanisms  transmit  non-­‐personally  identifiable  information  to  websites  for  different   purposes.  originally,  the  information  collected  by  these  mechanisms  was  used  to  enhance  user   experience  and  to  make  these  website  interactions  more  efficient.  tracking  mechanisms  can   record  user  actions  on  a  web  page  and  their  interaction  preferences.  using  these  data,  websites   can  for  example  direct  returning  visitors  to  a  specific  location  in  the  site,  allowing  those  visitors  to   resume  interaction  with  a  website  at  the  point  where  they  were  on  the  previous  visit.  using  the   internet  protocol  (ip)  address  of  a  user,  websites  can  display  information  relevant  to  the   geographic  area  where  a  user  is  located.  tracking  mechanisms  also  allow  a  website  to  remember   registration  details  and  the  items  users  have  put  in  their  shopping  basket  (harding,  reed  and  gray   2007).   tracking  mechanisms  are  also  of  great  use  to  webmasters,  supporting  the  optimization  of  website   design.  thus,  for  example,  these  mechanisms  can  inform  webmasters  of  users’  movements  on   their  websites:  what  pages  are  visited,  how  often  they  are  visited,  and  in  what  order.  they  can  also   indicate  the  common  entry  and  exit  points  for  a  specific  website.  this  information  can  be   leveraged  in  site  redesign  to  increase  user  satisfaction  and  traffic.     hidden  online  surveillance:  what  librarians  should  know  to  protect  their  own  privacy  and   that  of  their  patrons|  fortier  and  burkell  |  doi:  10.6017/ital.v34i3.5495   62   website  optimization  and  interaction  personalization  have  potential  benefit  to  users.  at  the  same   time,  however,  the  detailed  profile  of  user  activities,  potentially  aggregated  across  multiple  visits   to  different  websites,  presents  potential  privacy  risks.  the  information  gathered  through  tracking   mechanisms  can  allow  a  website  to  identify  browsing  and  information  access  habits,  to  infer  user   characteristics  including  location  and  some  demographics,  and  to  know  what  topics  or  products   are  of  particular  interest  to  a  user.   tracking  mechanisms  can  be  first-­‐party  or  third-­‐party,  and  the  difference  has  implications  for  the   detail  that  can  be  assembled  in  the  user  profile.  first-­‐party  mechanisms  are  set  by  directly  by  the   website  a  user  is  visiting,  while  third-­‐party  mechanisms  are  set  by  outside  companies  providing   services,  such  as  advertising,  analysis  of  user  patterns  and  social  media  integration,  on  the   primary  site.  first-­‐party  tracking  mechanisms  collect  information  about  a  site  visit  and  visitor  and   deliver  that  information  to  the  site  itself.  using  first-­‐party  tracking,  web  sites  can  provide   personalized  interaction,  integrating  visit  and  visitor  information  both  within  a  single  visit  and   across  multiple  visits  (randall  1997).  this  information  is  available  only  to  the  web  site  itself,  and   thus  neither  includes  information  about  visits  to  other  sites  nor  is  accessible  by  other  websites,   unless  the  information  is  sold  or  leaked  by  the  first-­‐party  site  (see  narayanan  2011).   third-­‐party  tracking  mechanisms,  by  contrast,  deliver  information  about  a  site  visit  and  visitor  to   a  third  party.  this  transaction  is  often  invisible  to  the  user,  and  the  information  is  transmitted   typically  without  explicit  user  consent.  third-­‐party  tracking  represents  a  greater  menace  to   privacy,  since  third  parties  have  a  presence  on  multiple  sites,  and  are  able  to  collect  information   about  users  and  their  activities  on  all  those  sites  and  integrate  that  information  across  sites  and   across  visits  into  a  single  detailed  user  profile  (see  mayer  and  mitchell  2012  for  a  discussion  of   privacy  problems  associated  with  third-­‐party  tracking).  research  demonstrates  that  third-­‐party   tracking  is  a  common  and  perhaps  even  ubiquitous  practice  (gomez,  pinnick  and  soltani  2009;   (burkell  and  fortier  2013).  it  is  not  uncommon  for  websites  to  have  trackers  from  more  than  one   third  party,  and  some  websites,  especially  popular  ones,  have  trackers  from  dozens  of  different   organizations:  gomez,  pinnick  and  soltani  (2009),  for  example,  found  100  unique  web  beacons  on   a  single  website.  furthermore,  the  same  tracking  companies  are  present  on  many  different   websites,  allowing  them  to  integrate  into  a  single  profile  information  about  visits  to  each  of  these   many  sites.  privacychoice1,  which  maintains  a  comprehensive  database  of  tracking  companies,   estimates  that  google  display  network  (doubleclick),  for  instance,  has  a  presence  on  57  percent  of   websites.  thus,  a  user  traveling  the  web  is  likely  to  be  tracked  by  doubleclick  on  more  than  half  of   the  sites  they  visit,  and  doubleclick  has  access  to  information  about  all  visits  to  each  of  these  many   sites.   worries  about  the  potential  privacy  breaches  that  mechanisms  for  tracking  a  user’s  activities   online  can  allow  are  not  new.  even  at  their  inception  in  the  mid-­‐1990s,  http  cookies  (also  known   as  browser  cookies)  were  generating  controversy  about  the  potential  invasion  of  privacy                                                                                                                               1 http://www.privacychoice.org/.   information  technologies  and  libraries  |  september  2015   63   (e.g.  randall  1997).  users,  however,  quickly  realized  that  they  could  manage  http  cookies  using   accessible  browser  settings  that  limit  or  even  entirely  disallow  the  practice  of  setting  cookies.  as  a   result,  websites,  advertisers  and  others  who  benefit  from  web  audience  segmentation  and   behavior  analytics  developed  newer  and  more  obscure  tracking  technologies  including   ‘supercookies’  and  web  beacons,  and  these  technologies  are  now  deployed  along  with  http   cookies  (sipior,  ward  and  mendoza  2011).  tracking  technologies  are  constantly  evolving  in   response  to  user  behavior  and  advertiser  demand,  therefore  keeping  up  to  date  is  an  ongoing   challenge  (see,  e.g.,  goodwin  2011).   http  cookies   http  cookies  were  originally  meant  to  help  web  developers  “invisibly”  gather  information  about   users  in  order  to  personalize  and  optimize  user  experience  (randall  1997).  these  cookies  are   simply  a  few  lines  of  text  shared  in  an  http  transaction,  and  a  typical  cookie  might  include  a  user   id,  the  time  of  a  visit,  and  the  ip  address  of  the  computer.  cookies  are  associated  with  a  specific   browser,  and  the  information  is  not  shared  between  different  browsers  on  the  same  machine:   thus,  the  cookies  stored  by  firefox  are  not  accessible  to  internet  explorer,  and  vice  versa.  cookies   do  not  usually  include  identifying  information  such  as  name  or  address,  and  they  are  able  to  do  so   if  and  only  if  the  user  has  explicitly  provided  this  information  to  the  website.  when  users  want  to   access  a  web  page,  their  browser  sends  a  request  to  the  server  for  the  specific  website  and  the   server  searches  the  hard  drive  for  a  cookie  file  from  this  site.  if  there  is  no  cookie,  a  unique   identifier  code  is  assigned  to  the  browser  and  a  cookie  file  is  saved  on  the  hard  drive.  if  there  is  a   cookie,  it  is  retrieved  and  the  information  is  used  to  personalize  and  structure  the  website   interaction  (for  a  detailed  description  of  the  mechanics  of  cookies,  see  kriscol  2001,  152–155).     some  http  cookies,  called  session  or  transient  cookies,  automatically  expire  when  the  browser  is   closed  (barth  2011).  they  are  mainly  used  to  keep  track  of  what  a  consumer  has  added  to  a   shopping  cart  or  to  allow  users  to  navigate  on  a  website  without  having  to  log  in  repeatedly.  other   http  cookies,  called  permanent,  persistent  or  stored  cookies,  are  configured  to  keep  track  of   users  until  the  cookie  reaches  its  expiration  date,  which  can  be  set  many  years  after  creation   (barth  2011).  permanent  http  cookies  can  be  easily  deleted  using  browser  management  tools   (sipior,  ward  and  mendoza  2011).  studies  have  shown  that  approximately  a  third  of  users  delete   cookies  once  a  month  (e.g.  comscore  2007;  2011).  such  behavior,  however,  displeases  advertisers,   as  it  leads  to  an  overestimation  of  the  number  of  true  unique  visitors  on  a  website  and  impede   user  tracking  (marshall  2005;  see  also  comscore  2007;  2011).   flash  cookies  and  other  ‘supercookies’   to  palliate  this  ‘attack’  on  http  cookies,  an  online  advertising  company,  united  virtualities,   developed  a  backup  system  for  cookies  using  the  local  shared  object  feature  of  adobe’s  flash   player  plug-­‐in:  the  persistent  identification  element  (sipior,  ward  and  mendoza  2011).  this  type   of  storage,  called  flash  player  local  shared  objects  or,  more  commonly,  flash  cookies,  shares   many  similarities  with  http  cookies  with  regard  to  their  tracking  capabilities,  storing  similar

non-­‐personally  identifying  information.  unlike  http  cookies,  however,  flash  cookies  do  not  have   an  expiration  date,  a  characteristic  that  makes  them  permanent  until  they  are  manually  deleted.   they  are  also  not  handled  by  a  browser,  but  are  stored  in  a  location  accessible  to  different   browsers  and  flash  widgets,  which  are  thus  all  able  to  access  the  same  cookie.  they  can  hold   much  more  data  (up  to  100  kb  by  default  compared  to  4  kb  for  http  cookies),  and  support  more   complex  data  types  than  http  cookies  (see  macdonald  and  cranor  2012  for  a  technical   comparison  of  http  and  flash  cookies).  moreover,  it  is  estimated  that  adobe’s  flash  player  is   installed  on  over  99  percent  of  personal  computers  (adobe  2011),  making  flash  cookies  usable  on   virtually  all  computers.   flash  cookies  represent  a  more  resilient  technology  for  tracking  than  http  cookies.  erasing   traditional  cookies  within  a  browser  does  not  affect  flash  cookies,  which  needs  to  be  erased  in  a   separate  panel  (sipior,  ward  and  mendoza  2011).  flash  cookies  also  have  the  ability  to  ‘respawn’   (or  recreate)  deleted  http  cookies.  a  website  using  flash  cookies  can  therefore  track  users  across   sessions  even  if  the  user  has  taken  reasonable  steps  to  avoid  this  type  of  online  profiling  (soltani   et  al.  2009),  and  although  it  is  declining  in  incidence,  this  practice  is  still  occurring,  sometimes  on   very  popular  websites  (ayenson  et  al.  2011;  macdonald  and  cranor  2012).     it  should  also  be  noted  that  other  internet  technologies  (e.g.  silverlight,  javascript,  and  html5),   which  have  so  far  attracted  less  attention  from  researchers,  use  local  storage  for  similar  purposes.   one  developer  even  created  the  ‘evercookie’,  a  very  persistent  cookie  incorporating  twelve  types   of  storage  mechanisms  available  in  a  browser  that  makes  data  persist  and  allows  for  respawning   (kamkar  2010),  a  method  investigated  by  the  national  security  agency  to  de-­‐anonymize  users  of   the  tor  network,  (‘tor  stinks’  presentation  2013),  a  network  which  aims  at  concealing  the   location  and  usage  of  users.   web  beacons   users’  online  behavior  can  also  be  monitored  by  web  beacons  (also  called  web  bugs,  clear  gifs  or   pixel  tags),  which  tiny  are  image  tags  embedded  within  a  document,  appearing  on  a  webpage  or   attached  to  an  email,  that  are  intended  to  be  unnoticed  (martin,  wu  and  alsaid  2003).  the  image   tag  creates  a  holding  space  for  a  referenced  image  residing  on  the  web,  and  beacons  transmit   information  to  a  remote  computer  when  the  document  (web  page  or  email)  is  viewed.  web   beacons  can  gather  information  on  their  own,  and  they  can  also  retrieve  information  from  a   previously  set  cookie  (angwin  2010;  see  martin,  wu  and  alsaid  2003  for  description  of  the   different  technological  abilities  of  web  beacons).  such  capacity  means,  according  to  the  privacy   foundation  (smith  2000;  quoted  in  martin,  wu  and  alsaid  2003),  that  beacons  could  potentially   transfer  to  a  third  party  demographic  data  and  personally  identifiable  information  (name,  address,   phone  number,  email  address,  etc.)  that  a  user  has  typed  on  a  page.  unlike  cookies,  beacons  are   not  tied  to  a  specific  server  and  can  track  users  over  multiple  web  sites  (schoen  2009).  beacons,   moreover,  cannot  be  managed  through  browser  settings.  while  blocking  third-­‐party  cookies  limit     information  technologies  and  libraries  |  september  2015   65   their  range  of  action,  it  does  not  preclude  beacons  from  gathering  information  on  their  own,  and   users  have  to  install  extensions  to  their  browser  to  efficiently  limit  the  effects  of  web  beacons.   strategies  for  identifying  behavioral  tracking   in  order  to  identify  privacy-­‐respecting  online  resources,  librarians  must  learn  to  assess  the   behavioral  tracking  activities  occurring  on  websites.  the  first  step  is  to  identify  and  review   website  privacy  policies.  privacy  guidelines  regulating  the  collection,  retention  and  use  of  personal   information  in  the  online  environment  usually  require  that  users  should  be  given  notice  of  website   practices  (e.g.,  fair  information  practice  principles2  proposed  in  1973  by  the  us  secretary’s   advisory  committee  on  automated  personal  data  systems,  the  convention  for  the  protection  of   individuals  with  regard  to  automatic  processing  of  personal  data  developed  by  the  council  of   europe  (1981),  and  the  organisation  for  economic  co-­‐operation  and  development  guidelines  on   the  protection  of  privacy  and  transborder  flows  of  personal  data3).  this  notice  is  typically  provided   in  privacy  policies  that  identify  what  information  is  collected,  how  it  is  used,  and  with  whom  it  is   shared.  regulatory  frameworks,  however,  did  not  originally  contemplate  the  collection  of  non-­‐ personally  identifiable  information.  while  such  disclosure  would  seem  to  be  consistent  with  the   fair  information  practice  principles,  the  current  mode  of  mode  of  control  is  in  many  cases  self-­‐ regulatory45,  and  full  compliance  with  notice  requirements  is  far  from  universal  (komanduri  et  al.   2011-­‐2012).  thus,  while  disclosure  of  behavioral  tracking  practices  in  websites  should  be  seen  as   diagnostic  of  the  presence  of  these  mechanisms,  lack  of  disclosure  cannot  be  interpreted  to  mean   that  the  site  does  not  engage  in  behavioral  tracking  (komanduri  et  al.  2011-­‐2012;  burkell  and   fortier  2013b).   furthermore,  privacy  policy  disclosures,  where  they  do  exist,  may  be  difficult  to  understand   (burkell  and  fortier  2013b).  website  privacy  policies  are  often  complex  (micheti,  burkell  and   steeves  2010).  they  tend  to  be  written  with  the  goal  of  protecting  a  website  owner  against   lawsuits  rather  than  informing  users  (earp  et  al.  2005;  pollach  2005).  pollach  (2005),  for  example,   details  a  variety  of  linguistic  strategies  that  serve  to  undermine  user  understanding  of  website   practices,  including  mitigation  and  enhancement,  obfuscation  of  reality,  relationship  building,  and   persuasive  appeals.  therefore,  even  if  many  websites  acknowledge  the  collection  of  non-­‐ personally  identifiable  information,  both  from  first-­‐  and  third-­‐party,  the  effectiveness  of  this   disclosure  is  limited,  making  privacy  policies  a  relatively  ineffective  tool  to  identify  behavioral   tracking  practices.                                                                                                                             2 the privacy act of 1974, 5 u.s.c. § 552a. 3 c(80)58/final, as amended on 11 july 2013 by c(2013)79. 4 for instance, the new self-regulatory guidelines for online behavioral advertising identify the need to provide notice to users when behavioral data is collected that allows the tracking of users across websites and over time (united states federal trade commission, 2009). 5 exceptions to this self-regulatory principle are increasing, including but not limited to the california online privacy protection act of 2003 (oppa), and the eu cookie directive (2009/136/ec) of the european parliament and of the council.   hidden  online  surveillance:  what  librarians  should  know  to  protect  their  own  privacy  and   that  of  their  patrons|  fortier  and  burkell  |  doi:  10.6017/ital.v34i3.5495   66   as  a  result,  librarians  need  to  develop  strategies  and  tools  that  allow  them  to  assess  directly  the   behavioral  tracking  practices  of  websites,  in  order  that  these  practices  can  be  considered  in   making  websites  recommendations.  different  protocols  can  be  followed  in  making  this   assessment,  but  they  should  be  built  around  the  following  guiding  principles  (see  burkell  and   fortier  2013a  for  a  full  discussion).  the  first  important  principle  is  that  each  website  should  be   visited  in  an  independent  session  to  eliminate  contamination.  each  website  under  consideration   should  be  visited  in  an  independent  session,  beginning  with  the  browser  at  an  about:blank  page,   with  clean  data  directories  (no  http  and  flash  cookies,  and  an  empty  cache).  the  evaluator   should  ensure  that  browser  settings  are  configured  to  allow  cookies,  tools  to  track  web  beacons   (e.g.,  the  ghostery6  browser  extension)  are  installed  in  the  browser,  and  adobe  flash,  via  the   website  storage  settings  panel  is  configured  to  accept  data.  the  website  should  then  be  accessed   directly  by  entering  the  domain  name  into  the  browser’s  navigation  bar.  evaluators  should  mimic   a  typical  user  interaction  with  the  website  on  many  pages  without  clicking  on  advertisements  or   following  links  to  outside  sites.  as  they  browse  through  the  site,  the  evaluator  should  record  the   web  beacons  and  trackers  identified  by  the  browser  extension  (e.g.,  ghostery).  at  the  end  of  the   session,  they  should  immediately  review  the  contents  of  the  browser  cookie  file  and  the  adobe   flash  panel  via  website  storage  settings,  recording  any  cookies  that  are  present.  privacychoice,  as   well  as  ghostery,  maintains  a  database  of  trackers  that  evaluators  can  use  to  identify  associated   privacy  risk.  while  all  third-­‐party  trackers  raise  some  privacy  issues,  some  of  them  put  users  at  a   greater  risk  than  others,  either  because  of  their  practices  or  their  presence  on  a  large  number  of   websites.  evaluators  should  take  that  into  account  when  making  a  decision.   strategies  for  limiting  behavioral  tracking   users  may  also  take  these  steps  to  identify  the  presence  of  behavioral  tracking,  and  digital  literacy   initiatives  should  provide  this  information  along  with  tools  and  strategies  that  users  can  employ   to  limit  tracking.  it  should  be  noted  that  elimination  of  all  behavioral  tracking  may  not  be  a   desirable  outcome  from  the  perspective  of  users  who  benefit  from  the  website  personalization   and  optimization  supported  by  these  mechanisms.  targeted  advertising  can  also  be  positive  for   many  people,  since  it  eliminates  unwanted  or  ‘useless’  advertisements.  ultimately,  a  user  must   decide  whether  he  or  she  wants  to  be  tracked.  digital  literacy  initiatives  should  raise  awareness  of   behavioral  tracking  and  provide  users  with  the  tools  they  need  to  identify  and  control  tracking   should  they  choose  to  do  so.     the  easiest  step  is  for  users  to  learn  how  to  manage  http  cookies  in  every  web  browser  that  they   use.  using  browser  settings,  users  can  decide  to  refuse  third-­‐party  cookies  or  even  all  cookies.  the   latter,  however,  will  make  the  make  the  browsing  experience  much  less  efficient  and  may  impede   users  from  accessing  some  websites.  users  should  also  learn  how  to  delete  cookies  and  they   should  be  encouraged  to  think  about  periodically  emptying  the  cookie  file  of  each  of  their   browsers.  controlling  flash  cookies  is  more  complex,  yet  crucial  considering  the  capabilities  of                                                                                                                             6 https://www.ghostery.com/.   information  technologies  and  libraries  |  september  2015   67   flash  cookies.  this  is  achieved  through  settings  on  the  adobe  website  storage  settings  panel.   browser  extensions,  such  as  ghostery  and  adblock  plus7,  can  be  added  to  most  browsers.   ghostery  allows  users  to  block  trackers,  either  on  a  tracker-­‐by-­‐tracker  basis,  a  site-­‐by-­‐site  basis  or   a  mixture  of  the  two.  also  customable,  adblock  plus  allows  users  to  block  either  all   advertisements  or  only  the  ones  they  do  not  want  to  see.  these  extensions,  however,  may  slow   down  internet  browsing.   users  can  also  change  their  internet  use  habits.  it  is  possible  for  user  to  use  search  engines  that  do   dot  store  any  non-­‐personally  identifiable  information,  such  as  ixquick8  and  duckduckgo9.  ixquick   returns  the  top  ten  results  from  multiple  search  engines.  it  only  sets  one  cookie  that  remembers  a   user’s  search  preferences  and  that  is  deleted  after  a  user  does  not  visit  ixquick  for  90  days.   duckduckgo,  which  returns  the  same  search  results  for  a  given  search  term  to  all  users,  aims  at   getting  information  from  the  best  sources  rather  than  the  most  sources.  while  these  search   engines  do  not  have  all  the  functionality  of  the  major  search  engines,  both  of  them  have  received   praise  (e.g.  mccracken  2011).  the  ultimate  solution,  one  that  allows  a  user  to  navigate  online  total   anonymity,  is  to  use  the  tor10  web  browser,  which  impedes  network  surveillance  or  traffic   analysis  and  which  the  u.s.  national  security  agency  has  characterized  as  “the  king  of  high  secure,   low  latency  internet  anonymity”  (schneier  2013).  the  anonymity  afforded  by  tor,  however,   comes  at  the  price  of  reduced  speed  and  limitations  to  available  content.   conclusion   it  is  widely  understood  that  online  privacy  is  at  risk,  threatened  by  the  actions  of  governmental   agencies  and  commercial  entities.  there  is  widespread  awareness  of  and  attention  to  the  risks   associated  with  the  collection  and  use  of  personally  identifiable  information,  but  less  attention  is   paid  to  an  equally  significant  issue:  the  collection  and  use  of  information  that  is  highly  personal   but  nonetheless  ‘non-­‐identifying’.  this  practice,  termed  ‘behavioral  tracking’,  is  the  focus  of  this   paper.  other  research  demonstrates  that  behavioral  tracking  is  widespread  (gomez,  pinnick  and   soltani  2009;  burkell  and  fortier  2013a),  but  users  demonstrate  only  a  limited  knowledge  of  the   practice  and  they  do  little  to  control  tracking  (comscore  2007;  2011;  rainie  et  al.  2013;  truste   2013).  we  argue  that  librarians  have  a  dual  professional  responsibility  with  respect  to  this  issue:   first,  librarians  should  be  aware  of  the  surveillance  practices  of  the  websites  they  recommend  to   patrons  and  take  these  practices  into  account  in  making  website  recommendations;  second,  digital   literacy  initiatives  spearheaded  by  librarians  include  a  focus  on  online  privacy,  and  provide   patrons  with  the  information  they  need  to  manage  their  own  online  privacy.     this  paper  presents  an  overview  of  online  behavioral  tracking  mechanisms,  and  provides   strategies  for  identifying  and  limiting  online  behavioral  tracking.  the  information  presented   provides  a  basic  understanding  of  tracking  mechanisms  along  with  practical  strategies  that

 10.6017/ital.v34i3.5495   68   librarians  can  use  to  evaluate  websites  with  respect  to  these  practices  and  strategies  that  can  be   used  to  limit  online  tracking.  we  recommend  that  website  evaluation  standards  be  extended  to   include  assessment  of  online  privacy  and  especially  behavioral  tracking.  we  also  recommend  that   librarians  actively  promote  digital  literacy  by  engaging  in  public  education  programs  that  take   privacy  and  other  digital  literacy  issues  into  account  (american  library  association  2013).  finally,   we

white information technology and libraries | march 2012 21 abstract this paper describes the ways in which libraries are currently implementing and managing webbased research guides (a.k.a. pathfinders, libguides, subject guides, etc.) by examining two sets of data from the spring of 2011. one set of data was compiled by visiting the websites of ninety-nine american university arl libraries and recording the characteristics of each site’s research guides. the other set of data is based on an online survey of librarians about the ways in which their libraries implement and maintain research guides. in conclusion, a discussion follows that includes implications for the library technology community. selected literature review while there has been significant research on library research guides, there has not been a recent survey either of the overall landscape or of librarian attitudes and practices. there has been recent work on the efficacy of research guides as well as strategies for their promotion. there is still work to be done on developing a strong return on investment metric for research guides, although the same could probably be said for other library technologies including websites, digital collections, and institutional repositories. subject-based research guides have a long history in libraries that predates the web as a servicedelivery mechanism. a literature-review article from 2007 found that research on the subject gained momentum around 1996 with the advent of electronic research guides, and that there was a need for more user-centric testing.1 by the mid-2000s, it was rare to find a library that did not offer research guides through its website.2 the format of guides has certainly shifted over time to database-driven efforts through local library programming and commercial offerings. a number of other articles start to answer some of the questions about usability posed in the 2007 literature review by vileno. in 2008, grays, del bosque, and costello used virtual focus groups as a test bed for guide evaluation.3 two articles from the august 2010 issue of the journal of library administration contain excellent literature reviews and look toward marketing, assessment, and best practices.4 also in 2010, vileno followed up on the 2007 literature review with usability testing that pointed toward a number of areas in which users experienced difficulties with research guides.5 jimmy ghaphery (jghapher@vcu.edu) is head, library information systems and erin white (erwhite@vcu.edu) is web systems librarian, virginia commonwealth university libraries, richmond, va. mailto:jghapher@vcu.edu library use of web-based research guides | ghaphery and white 22 in terms of cross-library studies, an interesting collaboration in 2008 between cornell and princeton universities found that students, faculty, and librarians perceived value in research guides, but that their qualitative comments and content analysis of the guides themselves indicated a need for more compelling and effective features.6 the work of morris and grimes from 1999 should also be mentioned; the authors surveyed 53 university libraries, finding that it was rare to find a library with formal management policies for their research guides.7 most recently, libguides has emerged as a leader in this arena, offering a popular software-as-aservice (saas) model and as such is not yet heavily represented in the literature. a multichapter libguides lita guide is pending publication and will cover such topics as implementing and managing libguides, setting standards for training and design, and creating and managing guides. arl guides landscape during the week of march 3rd, 2011, the authors visited the websites of 99 american university arl libraries to determine the prevalence and general characteristics of their subject-based research guides. in general, the visits reinforced the overarching theme within the literature that subject-based research guides are a core component of academic library web services. all 99 libraries offered research guides that were easy to find from the library home page. libguides was very prominent as a platform, in production at 67 of the 99 libraries. among these, it appeared that at least 5 libraries were in the process of migrating from a previous system (either a homegrown, database-driven site or static html pages) to libguides. in addition to the presence and platform, the authors recorded additional information about the scope and breadth of each site’s research guides. for each site, the presence of course-based research guides was recorded. in some cases the course guides had a separate listing, whereas in others they were intermingled with the subject-based research guides. course guides were found on 75 of the 99 libraries visited. of these, 63 were also libguides sites. it is certainly possible that course guides are being deployed at some of the other libraries but were not immediately visible in visiting the websites, or that course guides may be deployed through a course management system. nonetheless, it appears that the use of libguides encourages the presence of public-facing course guides. qualitatively, there was wide diversity of how course guides were organized and presented, varying from a simple a-to-z listing of all guides to separately curated landing pages specifically organized by discipline. the number of guides was recorded for each libguides site. it was possible to append “/browse.php?o=a” to the base url to determine how many guides and authors were published at each site. this php extension was the publicly available listing of all guides on each libguides platform. the “/browse.php?o=a” extension no longer publicly reports these statistics; however, findings could be reproduced by manually counting the number of guides and authors on each site. the authors confirmed the validity of this method in the fall of 2011 by revisiting four sites and finding that the numbers derived from manual counting were in line with the previous findings. of information technology and libraries | march 2012 23 the 63 libguides sites we observed, a total of 14,522 guides were counted from 2,101 authors for an average of 7 guides per author. on average, each site had 220 guides from 32 authors (median of 179 guides; 29 authors). at the high end of the scale, one site had 713 guides from 46 authors. based on the volume observed, libraries appear to be investing significant time toward the creation, and presumably the maintenance, of this content. in addition to creation and ongoing maintenance, such long lists of topics raise a number of usability issues that libraries will also be wise to keep in mind.8 survey the literature review and website visits call out two strong trends: 1. research guides are as commonplace as books in libraries, 2. libguides is the elephant in the room, so much so that it is hard to discuss research guides without discussing libguides. based on preliminary findings from the literature review and survey, we looked to further describe how libraries are supporting, innovating, implementing, and evaluating their research guides. a ten-question survey was designed to better understand how research guides sit within the cultural environment of libraries. it was distributed to a number of professional discussion lists the week of april 19, 2011 (see appendix). the following lists were used in an attempt to get a balance of opinion from populations of both technical and public services librarians: code4lib, web4lib, lita-l, lib-ref-l, and ili-l. the survey was made available for two weeks following the list announcements. survey response was very strong, with 198 responses (188 libraries) received without the benefit of any follow-up recruitment. ten institutions submitted more than one response. in these cases only the first response was included for analysis. we did not complete a response for our own institution. the vast majority (155, 82%) of respondents were from college or university libraries. of the remaining 33, 24 (13%) were from community college libraries, with only 9 (5%) identifying themselves as public, school, private, or governmental. among the college and university libraries, 17 (9%) identified themselves as members of the arl, which comprises 126 members.9 in terms of “what system best describes your research guides by subject?” the results were similar to the survey of arl websites. most libraries (129, 69%) reported libguides as their system, followed by “customized open source system” and “static html pages,” both at 20 responses (11% each). sixteen libraries (9%) reported using a homegrown system, with three libraries (2%) reporting “other commercial system.” in terms of initiating and maintaining a guides system, much of the work within libraries seems to be happening outside of library systems departments. when asked which statement best described who selected the guides system, 67 respondents (36%) indicated their library research library use of web-based research guides | ghaphery and white 24 guides were “initiated by public services,” followed closely by “more of a library-wide initiative” at 63 responses (34%). in the middle at 34 responses (18%) was “initiated by an informal crossdepartmental group.” only 10 respondents (5%) selected “initiated by systems,” with the top down approach of “initiated by administration” gathering 14 responses (7%). when narrowing the responses to those sites that are using libguides or campus guides, the portrait is not terribly different, with 36% library-wide, 35% public services, 18% informal cross-departmental, 7% administration, and systems trailing at 4%. likewise there was not a strong indication of library systems involvement in maintaining or supporting research guides. sixty-nine responses (37%) indicated “no ongoing involvement” and an additional 35 (19%) indicated “n/a we do not have a systems department.” there were only 21 responses (11%) stating “considerable ongoing involvement,” with the balance of 63 responses (34%) for “some ongoing involvement.” not surprisingly, there was a correlation between the type of research guide and the amount of systems involvement. for sites running a “customized open source system,” “other commercial system,” or “homegrown system,” at least 80% of responses indicated either “considerable” or “some” ongoing systems involvement. in contrast, 37% of sites running libguides or campusguides indicated “considerable” or “some” technical involvement. further, the libguides and campusguides users recorded the highest percentage (43%) of “no ongoing involvement” compared to 37% of all respondents. interestingly, 20% of libguides and campus guides users answered “n/a we do not have a systems department,” which is not significantly higher than all respondents for this question at 19%. the level of interaction between research guides and enterprise library systems was not reported as strong. when asked “which statement best describes the relationship between your web content management system and your research guides?” 112 responses (60%) indicated that “our content management system is independent of our research guides” with an additional 51 responses (27%) indicating that they did not have a content management system (cms). only 12 respondents (6%) said that their cms was integrated with their research guides with a remaining 13 (7%) saying that their cms was used for “both our website and our research guides.” a similar portrait was found in seeking out the relationship between research guides and discovery/federated search tools. when asked “which statement best describes the relationship between your discovery/federated search tool and your research guides?” roughly half of the respondents (96, 51%) did not have a discovery system (“n/a we do not have a discovery tool”). only 12 respondents (6%) selected “we prominently feature our discovery tool on our guides,” whereas more than double that number, 26 (14%), said “we typically do not include our discovery tool on our guides.” fifty four respondents (29%) took the middle path of “our discovery tool is one of many search options we feature on our guides.” in the case of both discovery systems and content management systems, it seems that research guides are typically not deeply integrated. when asked “what other type of content do you host on your research guides system?” respondents selected from a list of choices as reflected in table 1. information technology and libraries | march 2012 25 answer total percent libguides/campusguides course pages 127 68% 74% “how to” instruction 123 65% 77% alphabetical list of all databases 76 40% 42% “about the library” information (for example hours, directions, staff directory, event) 59 31% 35% digital collections 34 18% 19% everything—we use the research guide platform as our website 16 9% 9% none of the above 17 9% 2% table 1. other types of content hosted on research guides system these answers reinforce the portrait of integration within the larger library web presence. while the research guides platform is an important part of that presence, significant content is also being managed by libraries through other systems. it is also consistent with the findings from the arl website visits, where course pages were consistently found within the research guides platform. for sites reporting libguides or campusguides as their platform, inclusion of course pages and how-to instruction was even higher, at 74% and 77%, respectively. another multi-answer question sought to determine what types of policies are being used by libraries for the management of research guides: “which of the following procedures or policies do you have in place for your research guides?” responses are summarized in table 2. library use of web-based research guides | ghaphery and white 26 answer total percent percent using libguides/campusguides style guides for consistent presentation 105 56 58 maintenance and upkeep of guides 94 50 53 link checking 87 46 50 required elements such as contact information, chat, pictures, etc. 78 41 56 training for guide creators 73 39 43 transfer of guides to another author due to separation or change in duties 72 38 41 defined scope of appropriate content 43 23 22 allowing and/or moderating user tags, comments, ratings 36 19 25 none of the above 36 19 19 controlled vocabulary/tagging system for managing guides 23 12 25 table 2. management policies/procedures for research guides while nearly one in five libraries reported none of the policies in place at all, the responses indicate that there is effort being applied toward the management of these systems. the highest percentage for any given policy was 56% for “style guides for consistent presentation.” best practices in these areas could be emerging or many of these policies could be specific to individual library needs. as with the survey question on content, the research-guides platform also has a role with the libguides and campusguides users reporting much higher rates of policies for “controlled vocabulary/tagging” (25% vs. 12%) and “required elements” (56% vs. 41%). in both information technology and libraries | march 2012 27 of these cases, it is likely that the need for policies arise from the availability of these features and options that may not be present in other systems. based on this supposition, it is somewhat surprising that the libguides and campusguides sites reported the same lack of policy adoption (none of the above; 19%). the final question in the survey further explored the management posture for research guides by asking a free-text question: “how do you evaluate the success or failure of your research guides?” results were compiled into a spreadsheet. the authors used inductive coding to find themes and perform a basic data analysis on the responses, including a tally of which evaluation methods were used and how often. one in five institutions (37 respondents, 19.6%) looked only to usage stats, while seven respondents (4%) indicated that their library had performed usability testing as part of the evaluation. forty-our respondents (23.4%) said they had no evaluation method in place (“ouch! it hurts to write that.”), though many expressed an interest or plans to begin evaluation. another emerging theme included ten respondents who quantified success in terms of library adoption and ease of use. this included one respondent who had adopted libguides in light of prohibitive it regulations (“we choose libguides because it would not allow us to create class specific research webpages”). several institutions also expressed frustration with the survey instrument because they were in the process of moving from one guides system to another and were not sure how to address many questions. most responses indicated that there are more questions than answers regarding the efficacy of their research guides, though the general sentiment toward the idea of guides was positive, with words such as “positive,” “easy,” “like,” and “love” appearing in 16 responses. countering that, 5 respondents indicated that their libraries’ research-guides projects had fallen through. conclusion this study confirms previous research that web-based research guides are a common offering, especially in academic libraries. adding to this, we have recorded a quantitative adoption of libguides both through visiting arl websites and through a survey distributed to library listservs. further, this study did not find a consistent management or assessment practice for library research guides. perhaps the most interesting finding from this study is the role of library systems departments with regard to research guides. it appears that many library systems departments are not actively involved in either the initiation or ongoing support of web-based research guides. what are the implications for the library technology community and what questions arise for future research? the apparent ascendancy of libguides over local solutions is certainly worth considering and in part demonstrates some comfort within libraries for cloud computing and saas. time will tell how this might spread to other library systems. the popularity of libguides, at its heart a specialized content management system, also calls into question the vitality and adaptability of local content management system implementations in libraries. more generally, does the desire to professionally select and steward information for users on research guides indicate librarian misgivings about the usability of enterprise library systems? how do attitudes library use of web-based research guides | ghaphery and white 28 toward research guides differ between public services and technical services? hopefully these questions serve as a call for continued technical engagement with library research guides. what shape that engagement may have in the future is an open question, but based on the prevalence and descriptions of current implementations, such consideration by the library technology community is worthwhile. references 1. luigina vileno, “from paper to electronic, the evolution of pathfinders: a review of the literature,” reference services review 35, no. 3

. • a network serials management component; and, • an international/national serials system component. a regional program can address itself to these three facets of the environment, in the following manner. a regional serials programj grosch 203 the local library, whatever its size or type, must develop some system for internal control of its serials collections. this author feels that the local library should be free to adopt either nsdp or anglo-american cataloging rules for current serials but need not change its retrospective records unless it can really afford to, if such data became available in the future through the program herein proposed. ideally, such a conversion and uniformity has much to offer the library user, but costs would be too high for most libraries. also, small libraries and certain libraries, because of their physical conditions, may need to preserve differences. therefore, the local library can be urged to adopt nsdp i aacr as standard but cannot be forced to standardize because of the large retrospective conversion problem. the local library can develop its serials system independently or through partial or full support through a network-the regional serials data center under this plan. independent of whether it chooses to use the regional serials data center for such services its needs remain the same: • to identify the serial in hand; • to obtain cataloging copy for it; • to service its subscriptions, claims, binding; and • to produce some form of catalog showing its holdings and arranged to reflect its specific shelf arrangement. the networking serials management component represents the development of union catalogs, wherein members of the network can: • identify a serial; • identify who holds a specific issue; • provide interlibrary loan/photocopy service to obtain the actual document; and • provide a way to consolidate fragmentary sets, eliminate unnecessary duplication or provide more copies when needed, and broaden subject coverage among the network. union catalogs, document delivery services, and bibliographic reference assistance comprise the products that are used by the network component. the international/ national serials system component must be the vehicle to provide a uniform bibliographic description and local components. the issn and the nsdp record provide the means to this end. the machine-readable record at the regional serials data center would comprise at least the key elements of the international record, i.e. keytitle as supplied via nsdp from either national library or regional center input and the issn. beyond that, the regional center bibliographic data base should be structured to provide full bibliographic description according to aacr rules for current publications, accommodating the retrospective data as it is found in its region-at least until some national effort at conversion of superimposed records can be mounted. moreover, the regional center should be tailored to perform the functions that its local libraries deem important. this obviously will vary with the region and with time as regions will vary in size and their mix of libraries. 204 journal of library automation vol. 6/4 december 1973 figure 2 enumerates the functions and responsibilities of the respective parts of the regionally organized serials program illustrated in figure 1. this list is not meant to be all inclusive as other functions could be recognized by other libraries or regions. national se1·ials data program 1. assign issn/key-title to titles reported via national libraries and regional serials data centers. 2. create and maintain data base, indexes of key-titles, issn' s, etc. 3. create and maintain or accept surrogates from regional serials data centers. 4. maintain essential isds data elements, other isds elements. 5. maintain essential non-isds data elements or national library extensions via other data elements. 6. publish indexes to the data base at nsdp for use by regional serials data centers and national libraries. 7. transmit issn's and key-titles as assigned to the regional serials data centers and the national libraries. 8. carry out publisher relations to convince publishers of the need to use issn, etc. as well as foster some additional uniformity wherever possible. national libraries 1. provide cataloging copy-surrogate for newly cataloged titles-using new or available mechanisms such as marc, serline or nst to nsdp for key-titlesj issn assignments. 2. provide subscription ca.rdj tape cataloging copy to local libraries until a dual definition national serials data program record canbe developed and revised through the regional centers. 3. maintain national union list functions via nst, eventually coordinating with nsdp to provide key-title and issn entry points. regional centers 1. create and maintain regional center serials data base reflecting holdings of libraries in the region. 2. forward new title bibliographic/surrogate data to nsdp for issn/ key-title assignment if not processed by nsdp through national libraries or another regional center. 3. publish union catalogs or holdings in region for network library use. 4. process and provide machine/manual cataloging data for region use with m~rc, serline, nst type processing. 5. forward retrospective data to nsdp converted to their requirement$ for fig. 2. functions and responsibilities of the respective parts of a regionally organized serials program. a regional serials programjgros~h 205 retrospective issn/key-title assignment and addition to the central store atnsdp. 6. develop local library services as required. for example: a. catalog card production. b. book catalog production. c. oclc type serials check-in, claiming, binding, subscription system. d. document/ photocopy delivery system for interlibrary loan. e. coordinated acquisitions program for new serials, added copies. f. coordinate interlibrary transfers and consolidations of retrospective holdings. 7. communicate with other centers or nsdp to locate titles not supplied by local region. local library 1. notify regional center of new titles, changes, corrections to maintain regional data base. 2. use local library services as deemed necessary from regional center. 3. participate in document delivery / resource sharing/set consolidation within the region network. fig. 2.

record specifications are presently available and implemented through the nsdp data base. the nsdp i university of minnesota contract for a feasibility study will determine the costs and required bibliographic and programming support to convert locally generated data bases, i.e., the minnesota union list of serials ( muls) to nsdp requirements. the results of this feasibility study will determine the prospects for funding any proposals for actual conversion of local data bases such as muls. the current muls data base represents one model of a regional center data base, with the addition of issn and key-title as the links to the nsdp system and/ or augmentation to provide other kinds of services to local libraries participating in muls. creation of the system of regional centers would depend upon proposing and funding such a program based on the above work. establishment of a pilot regional center would be one manner in which such a plan could be tested, followed by further center establishment based on the results of the pilot program. with such a system in routine operation, the nsdp in its central role could focus its attention on the retrospective conversion-issn and key-title assignment possibly via some nationally coordinated cooperative venture among the regional centers or other contractors. conclusion obviously, any system for a serials program will have its problems. are206 journal of library automation vol. 6/ 4 december 1973 task i. development of isds record specifications for nsdp and other centers. 2. development of software/

the authors surveyed 138 urban libraries council members utilizing a combination of mobile visits, content analysis, and librarian interviews. the results show that nearly 95% of these libraries have at least one mobile website, mobile catalog, or mobile app. the libraries actively applied new approaches to meet each local community’s remote-access needs via new technologies, including app download links, mobile reference services, scan isbn, location navigation, and mobile printing. mobile services that libraries provide today are timely, convenient, and universally applicable. introduction the mobile internet has had a major impact on people’s lives and on how information is found located and accessed. today, library patrons are untethered from and free of the limitations of the desktop computer.1 the popularity of mobile devices has changed the relationship between libraries and patrons. mobile technology allows libraries to have the kind of connectivity with their patrons that did not exist previously. patrons no longer think that it is necessary for them to be physically in the library building to use library services, and they are eager to obtain 24/7 access to library resources anywhere using their mobile devices. mobile patrons need mobile libraries to provide them with services. in other words, “patrons want to have a library in their pocket.”2 as a result, libraries around the world are exploring and developing mobile services. according to the state of america’s libraries 2017 report by the american library association, the 50 us states, the district of columbia, and outlying territories have 8,895 public library administrative units (as well as 7,641 branches and bookmobiles). the vital role public libraries play in their communities has also expanded.3 as part of the main role of public libraries, us urban libraries need to embrace the developmental trend of the mobile internet to better serve their communities. the provision of mobile services in us urban libraries is worthy of study and is of great significance as a model for how other public libraries plan and implement their mobile services. mailto:yadon0619@hotmail.com

review definition and types of mobile devices and mobile services as early as 1991, mark weiser proposed “ubiquitous computing,” pointing out how people could obtain and handle information at anytime, anywhere, and in any way.4 with this expectation, the possibilities of using personal digital assistants (pdas) as mobile web browsers were researched in 1995.5 in combination with a wireless modem, library users are able to use pdas to access information services whenever they are needed. today, mobile devices are generally defined as units small enough to carry around in a pocket, falling into the categories of pdas, mobile phones, and personal media players.6 for many researchers, laptops are not included in the definition of mobile devices. although wireless laptops purportedly offer the opportunity to go “anywhere in the home,” laptops are generally used in a small set of locations, rather than moving fluidly through the home; wireless laptops are portable, but not mobile.7 in contrast, lippincott suggested that mobile devices should include laptops, netbooks, notebook computers, cell phones, audio players such as mp3 players, cameras, and other items.8 according to the “mobile strategy report” by the california digital library, mobile phones, e-readers, mp3 players, tablets, gaming devices, and pdas are common mobile devices.9 each mobile device has its own characteristics and the potential to connect to the internet from anywhere with a wi-fi network, driving widespread use and thus the provision of library mobile services. mobile services are services libraries offer to patrons via their mobile devices. these services as described herein comprise two categories: traditional library services modified to be available via mobile devices and services created for mobile devices.10 pope et al. listed several mobile services, including sms or text-messaging services, the my info quest project, digital collections, audiobooks, applications, and mobile-friendly websites.11 the california digital library pointed out that a growing number of university and public libraries are offering mobile services. libraries are creating mobile versions of library websites, using text messaging to communicate with patrons, developing mobile catalog searching, providing access to resources, and creating new tools and services, particularly for mobile devices.12 the most recognized mobile services in university libraries are mobile sites, mobile apps, mobile opacs, mobile access to databases, text messaging services, qr codes, augmented reality, and e books.13 both academic and public libraries’ use of web 2.0 applications and services include blogs, wikis, phone apps, qr codes, mash-ups, video or audio sharing, customized webpages, social media and social networking, and types of social tagging.14 this study focuses on the two most common mobile devices, mobile phones and tablets, and on the services provided to library patrons and local communities through mobile websites, mobile apps, and mobile catalogs. status of mobile services in us libraries mobile devices present a new and exciting opportunity for libraries of all types to provide information to people of all ages on the go, wherever they are.15 it is generally observed that there is an increased use of mobile technology in the library environment. information technology and libraries | june 2018 80 librarians see their users increasingly using mobile phones instead of laptops and desktop computers to search the catalog, check the library’s opening hours, and maintain contact with library staff.16 in an earlier investigation of 766 librarians, spires found that there was very little demand for services for mobile devices as of august 2007. at that time, relatively few libraries (18%) purchased content specifically for wireless handheld device use, and very few libraries (15%) reformatted content for these devices.17 however, a survey of public libraries completed by the american library association between september and november 2011 indicated interesting changes: 15% of library websites are optimized for mobile devices, and 12% of libraries use scanned codes (e.g. qr codes), and 7% of libraries have developed smartphone applications for access to library services; 36% of urban libraries have websites optimized for mobile devices, compared to 9% of rural libraries; 76% of libraries offer access to e-books; 70% of libraries use social networking tools such as facebook. 18 later studies revealed more significant changes. 99 association of research libraries member libraries were surveyed in 2012 to identify how many had optimized at least some services for the mobile web. apps were not investigated. the result showed that 83 libraries (84%) had a mobile website.19 a study in 2015 by liu and briggs showed that the top 100 university libraries in the united states offered one or more mobile services, with mobile websites, mobile access to the library catalog, mobile access to the library’s databases, e-books, and text messaging services being the most common. qr codes and augmented reality were less common.20 kim noted that “libraries are acknowledging that people expect to do just about everything on mobile devices and that more and more people are now using a mobile device as their primary access point for the web.”21 although librarians may have previously underestimated what people wanted to do using mobile devices, there is a growing understanding of the potential of these access points. research design survey samples while a growing number of users tend to access information remotely, urban libraries, as the most popular public-sector institutions and community centers, are facing great challenges in addressing the growing need for mobile services. the urban libraries council (ulc) (https://www.urbanlibraries.org), as an authoritative source founded in 1971, is the premier membership association of north america’s leading public library systems. ulc’s member libraries are in communities throughout the united states and canada, comprising a mix of institutions with varying revenue sources and governance structures, and serving communities with populations of differing sizes. ulc’s website lists 145 us and canadian urban libraries. since this study focused only on us urban libraries, 138 libraries were chosen as the study targets, and all were examined. https://www.urbanlibraries.org/ the provision of mobile services in us urban libraries | guo, liu, and bielefield 81

survey methods as mobile services are offered basically via wireless systems and mobile devices, a combination of research methods, including mobile website visits, content analysis, and librarian interviews, were applied for data collection. specifically, librarian interviews were employed as a verification and supplemental process to ensure that survey data were accurate and exhaustive. first, the authors utilized an iphone, an android mobile phone, and an ipad to access the websites of the 138 us urban libraries in the study sample to ascertain if these libraries have mobile websites or mobile catalogs and whether the platforms are operated properly. then the authors checked whether these libraries have mobile apps that can be downloaded from the apple app store or the google play store. the survey was conducted from june 18 to june 24, 2017. next, the authors went through all the mobile websites and the mobile apps the libraries provide to check the mobile services offered. the authors used a specially designed survey to collect data about each library’s mobile website and app (see table 1). the procedure of survey content analysis was conducted between june 25 and july 24, 2017, with the examination of each library’s services taking approximately 30 minutes. finally, for those libraries that had no mobile websites or mobile apps found through the website visits, the authors made interview requests to staff librarians via their online reference services such as live chat, web form and email. an additional purpose of this step was to confirm the accuracy of the survey data collected from website visits. the survey was conducted from july 22 to august 3, 2017. results and analysis results from the examination of mobile website visits, content analysis, and librarian interviews revealed what services us urban libraries provided as mobile services, how they were provided, and which were commonly provided. how many libraries provide mobile services? over 83% of us urban libraries have developed their own mobile websites (see figure 1) for communities they serve. the mobile website is currently the most popular service platform for mobile users. the provision of mobile services in us urban libraries | guo, liu, and bielefield 83 https://doi.org/10.6017/ital.v37i2.10170 figure 1. types of mobile services provided by libraries. promisingly, each test of these websites through the authors’ mobile devices, either smartphones or tablets, confirmed that all the study subjects can be accessed 100% of the time. these library websites, however, are not entirely built specially for mobile devices. while the majority of urban libraries have transformed their desktop websites into mobile sites with proper responsive design, about 17% are just smaller versions of their desktop websites (see figure 2). a responsive mobile website can react or change according to the needs of the users and the mobile device they’re viewing it on to achieve a good layout and content display. here, text and images change from a three-column to a single-column layout, and unnecessary images are hidden. the web address of a responsively designed mobile website is the same as the desktop website. responsive design is described as a long-term solution for addressing both designers’ and users’ needs.22 the survey found that 59% of libraries now have apps. our analysis of the earliest version of apps records indicate that los angeles public library was the first to use an app, in august 2010. mobile apps have advantages and disadvantages compared to mobile websites, and many libraries compared them and chose between the two. skokie (illinois) public library, as of october 2015, is no longer supporting the library’s mobile app because they claim the library’s website offers a better mobile experience. they also offer an easy access solution like that for a mobile app, with a message displayed to users: “miss having an icon on your home screen? bookmark the site to your home screen and you’ll have an icon to take you directly to this site.” 83% 59% 22% 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% mobile website

libraries providing mobile catalog services is only 22%. libraries can use multiple options to create one or more mobile service platforms. nearly half (46%) of us urban libraries have both mobile websites and mobile apps. according to the survey, 95% of libraries have at least one mobile website, mobile catalog, or mobile app. a survey the authors conducted in april 2014 found that only 81% of the urban libraries had at least one mobile website, mobile catalog, or mobile app (see figure 3). clearly, libraries are paying increasing attention to mobile services, and providing mobile services has become the unavoidable choice of libraries nowadays. figure 3. changes in the proportion of libraries that provide mobile services from 2014 to 2017. 19% 81% 2014 no mobile services at least one

what content do the mobile websites offer? through mobile website visits and content analysis, it was found that some types of information are available at all libraries, including “account login,” “events,” “locations and hours,” “contact us,” and “social media” (see figure 4). figure 4. components of mobile websites the proportion of library mobile sites that offer “support” and “downloadables” is 96% and 95%, respectively. among them, “support” generally includes donations to the library foundation, donation of books and other materials, and providing volunteer services; “downloadables” generally include e-books, e-magazines, and music. a total of 86% of the urban libraries set up “kids” and “teens” sections, providing specialized information services, such as storytime, games, events, book lists, homework help, volunteer information, and college information. a majority (62%) of libraries provide interlibrary loan information on mobile websites, but one library, palo alto (california) city library, no longer offers the costly interlibrary loan service as of july 2011. more than half (56%) of the libraries set up a “suggest a purchase” function and generally ask readers to provide title, author, publisher, year published, format, and other information in web form. some libraries display “recommendations” (26%) on their mobile websites. denver public library has a special column recommending books for children and teenagers and offers personalized reading suggestions: “tell us what you like to read and we’ll send you our recommendations in about a week.” many mobile websites will pop hints to the libraries’ mobile apps and link to the apple app store or the google play store after automatically identifying the user’s mobile phone operating system. this is helpful for promoting the use of the libraries’ apps, and it also provides great convenience for users. 100% 100% 100% 100% 100% 99% 96% 95% 86% 74% 62% 56% 32% 26% 0% 20%

websites in libraries is basically the same, but the content of their mobile apps varies widely. the reason is that the understanding of the various libraries about the functions an app should offer differs from one library to another. some of these apps were designed by software vendors, such as boopsie, sirsidynix, and bibliocommoms, but some were designed by the libraries themselves, leading to the absence of a uniform standard or template for the app design. survey results show that only “account login” and “catalog search” are available in all apps (see figure 5). “locations and hours” accounts for a high proportion of apps at 96%. the “locations” feature in many libraries apps, with the help of gps, helps users find their nearest library location. figure 5. components of mobile apps about 85% of apps provide “contact us.” click “contact us” in poudre river public library district and some other libraries’ apps, and you can directly call the library or send text messages via email. “scan isbn” is a unique feature of mobile apps, and 75% of apps provide this functionality. if a library user finds a book they need in a bookstore or elsewhere, they can scan the isbn to can see if that book is in the library’s collection. apps designed by bibliocommoms all have “bestsellers”, “recently reviewed”, “just ordered” and “my library” (see chart figure 6). in “my library,” the “checked out” section contains red alerts for “overdue,” yellow alerts for “due soon,” and “total items.” the “holds” section contains “ready for pickup,” “active holds,” and “paused holds.”. the “my shelves” section contains “completed,” “in progress,” and “for later.” in this way, users can clearly see the details of the books they have 100% 100% 96% 89% 85% 77% 75% 68% 46% 27% 24% 19% 18% 16%

6. an app designed by bibliocommoms. only 3% of apps have “kids” and “teens” sections, which differs greatly from the percentage of mobile websites that offer those sections (86%). what mobile reference services do libraries provide? according to the survey, the most common way for us urban libraries to provide mobile reference service is a web form, which is available in 86% of surveyed libraries (see figure 7). related to “call us,” a web form has the advantage of being independent from the library’s working hours. although users fill out and submit a web form, it is similar to email and, generally, librarians respond to the user’s e-mail address, but it does not require users to enter their own email system, as they only need to fill in the content required by the web form. therefore, it is more convenient to use. the authors believe that providing only an email address is not mobile reference service. the survey found that 6% of libraries do not have mobile reference services. information technology and libraries | june 2018 88 figure 7. mobile reference services provided by libraries. currently, 43% of libraries offer chat and instant messaging (im) services, which allow users to communicate with librarians instantly. for example, when gwinnett county (georgia) public library’s mobile website is visited, an “ask us” dialog box appears in the upper right corner of the site, which allows visitors to chat with librarians. outside of the library’s work hours, the box displays “sorry, chat is offline but you can still get help” (see figure 8). the county of los angeles public library provides four options for im. they are aim, google talk, yahoo! messenger, and msn messenger. figure 8. “ask us” on gwinnett county public library’s mobile website 86%

all the florida urban libraries surveyed offer reference services via the web form, chat, and text because an “ask a librarian” service administered by the tampa bay library consortium provides florida residents with those mobile reference services. the survey shows that only 8% of the libraries provide social media reference service in “ask a librarian.” the social media that provides reference service is either facebook or twitter. in fact, 100% of libraries have social media, and 100% of libraries have facebook and twitter, but most libraries do not use them to provide reference services. what social media do the libraries use? survey results showed that 100% of mobile websites display links to their social media, usually in the prominent position of the front page of the websites; 68% of apps have social media links. facebook and twitter are social media leaders, and now all libraries’ mobile websites have both (see figure 9). the survey conducted in 2014 showed that facebook and twitter had the highest occupancy rate, but only 61% of libraries offered facebook and 53% offered twitter. it is obvious that libraries have made great progress in the last three years in the application of social media. figure 9. social media being used by libraries. instagram and pinterest are both photo social media, and they are used 76% and 49%, respectively. as the leading social media in the video field, youtube is used by 67% of libraries. what mobile reservation services do libraries provide? mobile reservation services were found in 78% of all libraries’ mobile services. a majority (62%) of the libraries allow online reservation of a meeting room via web form or other forms, and 14% allow reserving a study room (see figure 10). some libraries only reserve a

session with a reference librarian or subject specialist at the library. in addition, several libraries, such as pasadena public library, allow reserving of exhibit space. how many libraries provide mobile printing? mobile printing services allow patrons to print to a library printer from outside the library or from their mobile device. patrons’ print jobs are available for pick up at the library. already, 43% of the libraries provide mobile printing service (see figure 11). it is expected that more libraries will provide this service. to print from a mobile device, patrons need to download an app that supports mobile printing. printeron is the more commonly used app, which has been used by oakland public library, and san mateo county (california) libraries, and others. however, san diego public library uses the your print cloud print system, and santa clara county (california) library uses smart alec. san mateo county libraries offers wireless printing from smartphones, tablets, and laptops at all of its locations, and its wireless printing includes mobile printing, web printing, and email printing. in addition, 14% of libraries offer wireless printing services but do not provide mobile printing services. for example, live oak public libraries in savannah, georgia, states that printing from laptops (pc and mac) is available in all branches, but they don’t have

mango languages (language learning), learningexpress and career transitions (job and career), lynda.com and tutor.com (education), morningstar (investment), world book (encyclopedias), worldcat (library resources worldwide), new york times (newspaper articles), driving-tests.org (testing preparation), and safari (technology). conclusion this study shows that mobile services have become popular in us urban libraries as of summer 2017, with 95% offering one or more types of mobile service. responsive mobile websites and mobile apps are the main platforms of current mobile services. the us urban libraries are terribly striving to meet local community’s remote access needs via new technologies. compared with desktop websites, mobile websites and apps for mobile devices offer services that are more accessible, smarter and interactive for local users. some mobile websites automatically prompt the user to install the libraries’ apps; many libraries’ apps offer the “scan isbn” function, making it convenient for the user to scan a book title at any time to see if it is in the library’s collection; “location” provides gps positioning and navigation services for users; “contact us” can directly link telephone, text, and email. libraries are actively developing and adding more mobile services, such as mobile reservation services and mobile printing services. the development of mobile technology has provided the support for libraries to offer mobile services. a future world of users accessing services provided by the libraries at anytime, anywhere, and in any way is getting closer and closer. acknowledgements this work was supported by grant no. 14ctq028 from the national social science foundation of china. references 1jason griffey, mobile technology and

(bibliothekspraxis, 1) as the first volume in a new series called bibliothekspraxis (library practice), v erlag dokumentation has published a short monograph on library automation by paul n iewalda, of the university library of regensburg. niewalda has written an introductory text, in german, condensing the standard, largely american, literature on the subject. his treatment is concise, wellwritten, and · well-organized. computer capabilities, and existing library applications in the united states and elsewhere, are carefully delineated. the text is thoroughly documented, with a large number of notes and a useful bibliography included. the book addresses itself to the german reader and, in fact, much is already familiar to american librarians. yet niewalda's frequent references to the ·european, particularly the german, library automation scene enhance the book's value. the author is clearly well informed both about library automation in general, and about local practice and problems. he brings to his task common sense and sound judgment. the work is recommended to those readers having a general interest in foreign developments in the field of library automation. s. micha namenwirth university of california, berkeley dictionanj of library science, information and documentation in six languages. compiled and artanged by w. e. clason. amsterdam: elsevier scientific publ. co., 1973. the basic table, a numbered list of entries for 5,439 english language words and phrases, alphabetically arranged, forms the body of the dictionary of library science, information and documentation. each entry consists ·of a serial number, the english term (american and/or british), equivalents in french, spanish, italian, dutch; and german, and a code identifying the book reviews 123 vocabulary with which the term is associated. hence, there are separate entries for volume as a book trade or library term and as an information processing term. many entries are augmented by brief definitions. english synonyms are also frequently given; in general these are terms from which references have been made. in such cases entry is under the synonym which files first. this practice produces some apparently eccentric choices; e.g., pseudonym, see allonym; udc, see brussels system. following the basic ' table are indexes for the five non-english languages. numerical references are given to basic table entries in which the index term is cited. german band is found not only in the first volume entry mentioned above but also in the bookbinding and information processing entries for tape. criteria employed for the selection of entries are unexplained. ibm's data pro-·' cessing glossary and the american national standard vocabulary for information processing appear to have been important sources of information processing terms. the glossary in anglo-american cataloging rules was evidently not used. it is clear that some of the source lists used were in other languages. the juxtaposition of related vocabularies which often put the same words to different uses presents difficulties which the approach taken here seems capable of handling. nevertheless the work as executed has flaws which reduce its effectiveness. the notions of synonymy and nonsynonymy among the english terms are puzzling. definitions are frequently unclear and occasionally wrong. there are cases in which the non-english equivalents for a single' term are certainly not synonymous with each other. the utility of the mdexes would be enhanced if the number of nonenglish synonyms given were greater. however, if approached with care, the volume can ·provide much useful information. in works of this type it is probably unfair to expect perfection. besides, a dictionary which manages to encompass both negative entropy (information theory) and scrivener's palstj (authors and authorship) has to be interesting, at least. charles w. husbands harvard universitv library generating collaborative systems for digital libraries | hilera et al. 195 josé r. hilera, carmen pagés, j. javier martínez, j. antonio gutiérrez, and luis de-marcos an evolutive process to convert glossaries into ontologies dictionary, the outcome will be limited by the richness of the definition of terms included in that dictionary. it would be what is normally called a “lightweight” ontology,6 which could later be converted into a “heavyweight” ontology by implementing, in the form of axioms, knowledge not contained in the dictionary. this paper describes the process of creating a lightweight ontology of the domain of software engineering, starting from the ieee standard glossary of software engineering terminology.7 ■■ ontologies, the semantic web, and libraries within the field of librarianship, ontologies are already being used as alternative tools to traditional controlled vocabularies. this may be observed particularly within the realm of digital libraries, although, as krause asserts, objections to their use have often been raised by the digital library community.8 one of the core objections is the difficulty of creating ontologies as compared to other vocabularies such as taxonomies or thesauri. nonetheless, the semantic richness of an ontology offers a wide range of possibilities concerning indexing and searching of library documents. the term ontology (used in philosophy to refer to the “theory about existence”) has been adopted by the artificial intelligence research community to define a categorization of a knowledge domain in a shared and agreed form, based on concepts and relationships, which may be formally represented in a computer readable and usable format. the term has been widely employed since 2001, when berners-lee et al. envisaged the semantic web, which aims to turn the information stored on the web into knowledge by transforming data stored in every webpage into a common scheme accepted in a specific domain.9 to accomplish that task, knowledge must be represented in an agreed-upon and reusable computer-readable format. to do this, machines will require access to structured collections of information and to formalisms which are based on mathematical logic that permits higher levels of automatic processing. technologies for the semantic web have been developed by the world wide web consortium (w3c). the most relevant technologies are rdf (resource description this paper describes a method to generate ontologies from glossaries of terms. the proposed method presupposes an evolutionary life cycle based on successive transformations of the original glossary that lead to products of intermediate knowledge representation (dictionary, taxonomy, and thesaurus). these products are characterized by an increase in semantic expressiveness in comparison to the product obtained in the previous transformation, with the ontology as the end product. although this method has been applied to produce an ontology from the “ieee standard glossary of software engineering terminology,” it could be applied to any glossary of any knowledge domain to generate an ontology that may be used to index or search for information resources and documents stored in libraries or on the semantic web. f rom the point of view of their expressiveness or semantic richness, knowledge representation tools can be classified at four levels: at the basic level (level 0), to which dictionaries belong, tools include definitions of concepts without formal semantic primitives; at the taxonomies level (level 1), tools include a vocabulary, implicit or explicit, as well as descriptions of specialized relationships between concepts; at the thesauri level (level 2), tools further include lexical (synonymy, hyperonymy, etc.) and equivalence relationships; and at the reference models level (level 3), tools combine the previous relationships with other more complex relationships between concepts to completely represent a certain knowledge domain.1 ontologies belong at this last level. according to the hierarchic classification above, knowledge representation tools of a particular level add semantic expressiveness to those in the lowest levels in such a way that a dictionary or glossary of terms might develop into a taxonomy or a thesaurus, and later into an ontology. there are a variety of comparative studies of these tools,2 as well as varying proposals for systematically generating ontologies from lower-level knowledge representation systems, especially from descriptor thesauri.3 this paper proposes a process for generating a terminological ontology from a dictionary of a specific knowledge domain.4 given the definition offered by neches et al. (“an ontology is an instrument that defines the basic terms and relations comprising the vocabulary of a topic area as well as the rules for combining terms and relations to define extensions to the vocabulary”)5 it is evident that the ontology creation process will be easier if there is a vocabulary to be extended than if it is developed from scratch. if the developed ontology is based exclusively on the josé r. hilera (jose.hilera@uah.es) is professor, carmen pagés (carmina.pages@uah.es) is assistant professor, j. javier martínez (josej.martinez@uah.es) is professor, j. antonio gutiérrez (jantonio.gutierrez@uah.es) is assistant professor, and luis de-marcos (luis.demarcos@uah.es) is professor, department of computer science, faculty of librarianship and documentation, university of alcalá, madrid, spain. 196 information technology and libraries | december 2010 configuration management; data types; errors, faults, and failures; evaluation techniques; instruction types; language types; libraries; microprogramming; operating systems; quality attributes; software documentation; software and system testing; software architecture; software development process; software development techniques; and software tools.15 in the glossary, entries are arranged alphabetically. an entry may consist of a single word, such as “software,” a phrase, such as “test case,” or an acronym, such as “cm.” if a term has more than one definition, the definitions are numbered. in most cases, noun definitions are given first, followed by verb and adjective definitions as applicable. examples, notes, and illustrations have been added to clarify selected definitions. cross-references are used to show a term’s relations with other terms in the dictionary: “contrast with” refers to a term with an opposite or substantially different meaning; “syn” refers to a synonymous term; “see also” refers to a related term; and “see” refers to a preferred term or to a term where the desired definition can be found. figure 2 shows an example of one of the definitions of the glossary terms. note that definitions can also include framework),10 which defines a common data model to specify metadata, and owl (ontology web language),11 which is a new markup language for publishing and sharing data using web ontologies. more recently, the w3c has presented a proposal for a new rdf-based markup system that will be especially useful in the context of libraries. it is called skos (simple knowledge organization system), and it provides a model for expressing the basic structure and content of concept schemes, such as thesauri, classification schemes, subject heading lists, taxonomies, folksonomies, and other similar types of controlled vocabularies.12 the emergence of the semantic web has created great interest within librarianship because of the new possibilities it offers in the areas of publication of bibliographical data and development of better indexes and better displays than those that we have now in ils opacs.13 for that reason, it is important to strive for semantic interoperability between the different vocabularies that may be used in libraries’ indexing and search systems, and to have compatible vocabularies (dictionaries, taxonomies, thesauri, ontologies, etc.) based on a shared standard like rdf. there are, at the present time, several proposals for using knowledge organization systems as alternatives to controlled vocabularies. for example, folksonomies, though originating within the web context, have been proposed by different authors for use within libraries “as a powerful, flexible tool for increasing the user-friendliness and interactivity of public library catalogs.”14 authors argue that the best approach would be to create interoperable controlled vocabularies using shared and agreed-upon glossaries and dictionaries from different domains as a departure point, and then to complete evolutive processes aimed at semantic extension to create ontologies, which could then be combined with other ontologies used in information systems running in both conventional and digital libraries for indexing as well as for supporting document searches. there are examples of glossaries that have been transformed into ontologies, such as the cambridge healthtech institute’s “pharmaceutical ontologies glossary and taxonomy” (http://www.genomicglossaries.com/content/ontolo gies.asp), which is an “evolving terminology for emerging technologies.” ■■ ieee standard glossary of software engineering terminology to demonstrate our proposed method, we will use a real glossary belonging to the computer science field, although it is possible to use any other. the glossary, available in electronic format (pdf), defines approximately 1,300 terms in the domain of software engineering (figure 1). topics include addressing assembling, compiling, linking, loading; computer performance evaluation; figure 1. cover of the glossary document generating collaborative systems for digital libraries | hilera et al. 197 4. define the classes and the class hierarchy 5. define the properties of classes (slots) 6. define the facets of the slots 7. create instances as outlined in the introduction, the ontology developed using our method is a terminological one. therefore we can ignore the first two steps in noy’s and mcguinness’ process as the concepts of the ontology coincide with the terms of the glossary used. any ontology development process must take into account the basic stages of the life cycle, but the way of organizing the stages can be different in different methods. in our case, since the ontology has a terminological character, we have established an incremental development process that supposes the natural evolution of the glossary from its original format (dictionary or vocabulary format) into an ontology. the proposed life cycle establishes a series of steps or phases that will result in intermediate knowledge representation tools, with the final product, the ontology, being the most semantically rich (figure 4). therefore this is a product-driven process, in which the aim of every step is to obtain an intermediate product useful on its own. the intermediate products and the final examples associated with the described concept. in the resulting ontology, the examples were included as instances of the corresponding class. in figure 2, it can be seen that the definition refers to another glossary on programming languages (std 610.13), which is a part of the series of dictionaries related to computer science (“ieee std 610,” figure 3). other glossaries which are mentioned in relation to some references about term definitions are 610.1, 610.5, 610.7, 610.8, and 610.9. to avoid redundant definitions and possible inconsistencies, links must be implemented between ontologies developed from those glossaries that include common concepts. the ontology generation process presented in this paper is meant to allow for integration with other ontologies that will be developed in the future from the other glossaries. in addition to the explicit references to other terms within the glossary and to terms from other glossaries, the textual definition of a concept also has implicit references to other terms. for example, from the phrase “provides features designed to facilitate expression of data structures” included in the definition of the term high order language (figure 2), it is possible to determine that there is an implicit relationship between this term and the term data structure, also included in the glossary. these relationships have been considered in establishing the properties of the concepts in the developed ontology. ■■ ontology development process many ontology development methods presuppose a life cycle and suggest technologies to apply during the process of developing an ontology.16 the method described by noy and mcguinness is helpful when beginning this process for the first time.17 they establish a seven-step process: 1. determine the domain and scope of the ontology 2. consider reusing existing ontologies 3. enumerate important terms in the ontology figure 2. example of term definition in the ieee glossary figure 3. ieee computer science glossaries 610—standard dictionary of computer terminology 610.1—standard glossary of mathematics of computing terminology 610.2—standard glossary of computer applications terminology 610.3—standard glossary of modeling and simulation terminology 610.4—standard glossary of image processing terminology 610.5—standard glossary of data management terminology 610.6—standard glossary of computer graphics terminology 610.7—standard glossary of computer networking terminology 610.8—standard glossary of artificial intelligence terminology 610.9—standard glossary of computer security and privacy terminology 610.10—standard glossary of computer hardware terminology 610.11—standard glossary of theory of computation terminology 610.12—standard glossary of software engineering terminology 610.13—standard glossary of computer languages terminology high order language (hol). a programming language that requires little knowledge of the computer on which a program will run, can be translated into several difference machine languages, allows symbolic naming of operations and addresses, provides features designed to facilitate expression of data structures and program logic, and usually results in several machine instructions for each program statement. examples include ada, cobol, fortran, algol, pascal. syn: high level language; higher order language; third generation language. contrast with: assembly language; fifth generation language; fourth generation language; machine language. note: specific languages are defined in p610.13 198 information technology and libraries | december 2010 since there are terms with different meanings (up to five in some cases) in the ieee glossary of software engineering terminology, during dictionary development we decided to create different concepts (classes) for the same term, associating a number to these concepts to differentiate them. for example, there are five different definitions for the term test, which is why there are five concepts (test1–test5), corresponding to the five meanings of the term: (1) an activity in which a system or component is executed under specified conditions, the results are observed or recorded, and an evaluation is made of some aspect of the system or component; (2) to conduct an activity as in (1); (3) a set of one or more test cases; (4) a set of one or more test procedures; (5) a set of one or more test cases and procedures. taxonomy the proposed lifecycle establishes a stage for the conversion of a dictionary into a taxonomy, understanding taxonomy as an instrument of concepts categorization, product are a dictionary, which has a formal and computer processed structure, with the terms and their definitions in xml format; a taxonomy, which reflects the hierarchic relationships between the terms; a thesaurus, which includes other relationships between the terms (for example, the synonymy relationship); and, finally, the ontology, which will include the hierarchy, the basic relationships of the thesaurus, new and more complex semantic relationships, and restrictions in form of axioms expressed using description logics.18 the following paragraphs describe the way each of these products is obtained. dictionary the first step of the proposed development process consists of the creation of a dictionary in xml format with all the terms included in the ieee standard glossary of software engineering terminology and their related definitions. this activity is particularly mechanical and does not need human intervention as it is basically a transformation of the glossary from its original format (pdf) into a format better suited to the development process. all formats considered for the dictionary are based on xml, and specifically on rdf and rdf schema. in the end, we decided to work with the standards daml+oil and owl,19 though we are not opposed to working with other languages, such as skos or xmi,20 in the future. (in the latter case, it would be possible to model the intermediate products and the ontology in uml graphic models stored in xml files.)21 in our project, the design and implementation of all products has been made using an ontology editor. we have used oiled (with oilviz plugin) as editor, both because of its simplicity and because it allows the exportation to owl and daml formats. however, with future maintenance and testing in mind, we decided to use protégé (with owl plugin) in the last step of the process, because this is a more flexible environment with extensible modules that integrate more functionality such as ontology annotation, evaluation, middleware service, query and inference, etc. figure 5 shows the dictionary entry for “high order language,” which appears in figure 2. note that the dictionary includes only owl:class (or daml:class) to mark the term; rdf:label to indicate the term name; and rdf:comment to provide the definition included in the original glossary. figure 4. ontology development process <owl:class rdf:about=”#highorderlanguage”> <rdfs:label>highorderlanguage</rdfs:label> <rdfs:comment><![cdata[a programming language that requires little knowledge of the computer on which a program will run, can be translated into several different machine languages, allows symbolic naming of operations and addresses, provides features designed to facilitate expression of data structures and program logic, and usually results in several machine instructions for each program statement.]]> </rdfs:comment> </owl:class> figure 5. example of dictionary entry generating collaborative systems for digital libraries | hilera et al. 199 example, when analyzing the definition of the term compiler: “(is) a computer program that translates programs expressed in a high order language into their machine language equivalent,” it is possible to deduce that compiler is a subconcept of computer program, which is also included in the glossary.) in addition to the lexical or syntactic analysis, it is necessary for an expert in the domain to perform a semantic analysis to complete the development of the taxonomy. the implementation of the hierarchical relationships among the concepts is made using rdfs:subclassof, regardless of whether the taxonomy is implemented in owl or daml format, since both languages specify this type of relationship in the same way. figure 6 shows an example of a hierarchical relationship included in the definition of the concept pictured in figure 5. thesaurus according to the international organization for standardization (iso), a thesaurus is “the vocabulary of a controlled indexing language, formally organized in order to make explicit the a priori relations between concepts (for example ‘broader’ and ‘narrower’).”25 this definition establishes the lexical units and the semantic relationships between these units as the elements that constitute a thesaurus. the following is a sample of the lexical units: ■■ descriptors (also called “preferred terms”): the terms used consistently when indexing to represent a concept that can be in documents or in queries to these documents. the iso standard introduces the option of adding a definition or an application note to every term to establish explicitly the chosen meaning. this note is identified by the abbreviation sn (scope note), as shown in figure 7. ■■ non-descriptors (“non-preferred terms”): the synonyms or quasi-synonyms of a preferred term. a nonpreferred term is not assigned to documents submitted to an indexing process, but is provided as an entry point in a thesaurus to point to the appropriate descriptor. usually the descriptors are written in capital letters and the nondescriptors in small letters. ■■ compound descriptors: the terms used to represent complex concepts and groups of descriptors, which allow for the structuring of large numbers of thesaurus descriptors into subsets called micro-thesauri. in addition to lexical units, other fundamental elements of a thesaurus are semantic relationships between these units. the more common relationships between lexical units are the following: ■■ equivalence: the relationship between the descriptors and the nondescriptors (synonymous and that is, as a systematical classification in a traditional way. as gilchrist states, there is no consensus on the meaning of terms like taxonomy, thesaurus, or ontology.22 in addition, much work in the field of ontologies has been done without taking advantage of similar work performed in the fields of linguistics and library science.23 this situation is changing because of the increasing publication of works that relate the development of ontologies to the development of “classic” terminological tools (vocabularies, taxonomies, and thesauri). this paper emphasizes the importance and usefulness of the intermediate products created at each stage of the evolutive process from glossary to ontology. the end product of the initial stage is a dictionary expressed as xml. the next stage in the evolutive process (figure 4) is the transformation of that dictionary into a taxonomy through the addition of hierarchical relationships between concepts. to do this, it is necessary to undertake a lexicalsemantic analysis of the original glossary. this can be done in a semiautomatic way by applying natural language processing (nlp) techniques, such as those recommended by morales-del-castillo et al.,24 for creating thesauri. the basic processing sequence in linguistic engineering comprises the following steps: (1) incorporate the original documents (in our case the dictionary obtained in the previous stage) into the information system; (2) identify the language in which they are written, distinguishing independent words; (3) “understand” the processed material at the appropriate level; (4) use this understanding to transform, search, or traduce data; (5) produce the new media required to present the produced outcomes; and finally, (6) present the final outcome to human users by means of the most appropriate peripheral device—screen, speakers, printer, etc. an important aspect of this process is natural language comprehension. for that reason, several different kinds of programs are employed, including lemmatizers (which implement stemming algorithms to extract the lexeme or root of a word), morphologic analyzers (which glean sentence information from their constituent elements: morphemes, words, and parts of speech), syntactic analyzers (which group sentence constituents to extract elements larger than words), and semantic models (which represent language semantics in terms of concepts and their relations, using abstraction, logical reasoning, organization and data structuring capabilities). from the information in the software engineering dictionary and from a lexical analysis of it, it is possible to determine a hierarchical relationship when the name of a term contains the name of another one (for example, the term language and the terms programming language and hardware design language), or when expressions such as “is a” linked to the name of another term included in the glossary appear in the text of the term definition. (for 200 information technology and libraries | december 2010 indicating that high order language relates to both assembly and machine languages. the life cycle proposed in this paper (figure 4) includes a third step or phase that transforms the taxonomy obtained in the previous phase into a thesaurus through the incorporation of relationships between the concepts that complement the hierarchical relations included in the taxonomy. basically, we have to add two types of relationships—equivalence and associative, represented in the standard thesauri with uf (and use) and rt respectively. we will continue using xml to implement this new product. there are different ways of implementing a thesaurus using a language based on xml. for example, matthews et al. proposed a standard rdf format,26 where as hall created an ontology in daml.27 in both cases, the authors modeled the general structure of quasi-synonymous). iso establishes that the abbreviation uf (used for) precedes the nondescriptors linked to a descriptor; and the abbreviation use is used in the opposite case. for example, a thesaurus developed from the ieee glossary might include a descriptor “high order language” and an equivalence relationship with a nondescriptor “high level language” (figure 7). ■■ hierarchical: a relationship between two descriptors. in the thesaurus one of these descriptors has been defined as superior to the other one. there are no hierarchical relationships between nondescriptors, nor between nondescriptors and descriptors. a descriptor can have no lower descriptors or several of them, and no higher descriptors or several of them. according to the iso standard, hierarchy is expressed by means of the abbreviations bt (broader term), to indicate the generic or higher descriptors, and nt (narrower term), to indicate the specific or lower descriptors. the term at the head of the hierarchy to which a term belongs can be included, using the abbreviation tt (top term). figure 7 presents these hierarchical relationships. ■■ associative: a reciprocal relationship that is established between terms that are neither equivalent nor hierarchical, but are semantically or conceptually associated to such an extent that the link between them should be made explicit in the controlled vocabulary on the grounds that it may suggest additional terms for use in indexing or retrieval. it is generally indicated by the abbreviation rt (related term). there are no associative relationships between nondescriptors and descriptors, or between descriptors already linked by a hierarchical relation. it is possible to establish associative relationships between descriptors belonging to the same or different category. the associative relationships can be of very different types. for example, they can represent causality, instrumentation, location, similarity, origin, action, etc. figure 7 shows two associative relations, .. high order language (descriptor) sn a programming language that... uf high level language (no-descriptor) uf third generation language (no-descriptor) tt language bt programming language nt object oriented language nt declarative language rt assembly language (contrast with) rt machine language (contrast with) .. high level language use high order language .. third generation language use high order language .. figure 7. fragment of a thesaurus entry figure 6. example of taxonomy entry <owl:class rdf:about="#highorderlanguage"> ... <rdfs:subclassof> <owl:class rdf:about="#programminglanguage"/> </rdfs:subclassof> </owl:class> generating collaborative systems for digital libraries | hilera et al. 201 terms. for example: <owl:objectproperty rdf:about="#uf"> <owl:inverseof rdf:resource="#use"/>. or using the glossary notation: <owl:objectproperty rdf:about="#syn"> <owl:inverseof rdf:resource="#see"/>. ■■ the rest of the associative relationships (rt) that were included in the thesaurus correspond to the cross-references of the type “contrast with” and “see also” that appear explicitly in the ieee glossary. ■■ neither compound descriptors nor groups of descriptors have been implemented because there is no such structure in the glossary. ontology ding and foo state that “ontology promotes standardization and reusability of information representation through identifying common and shared knowledge. ontology adds values to traditional thesauri through deeper semantics in digital objects, both conceptually, relationally and machine understandably.”29 this semantic richness may imply deeper hierarchical levels, richer relationships between concepts, the definition of axioms or inference rules, etc. the final stage of the evolutive process is the transformation of the thesaurus created in the previous stage into an ontology. this is achieved through the addition of one or more of the basic elements of semantic complexity that differentiates ontologies from other knowledge representation standards (such as dictionaries, taxonomies, and thesauri). for example: ■■ semantic relationships between the concepts (classes) of the thesaurus have been added as properties or ontology slots. ■■ axioms of classes and axioms of properties. these are restriction rules that are declared to be satisfied by elements of ontology. for example, to establish disjunctive classes (<owl:class rdf:about ="*higorderlanguage"> <owl:disjointwith> <owl:class rdf:about="* machinelanguage"/>), have been defined, and quantification restrictions (existential or universal) and cardinality restrictions in the relationships have been implemented as properties. software based on techniques of linguistic analysis has been developed to facilitate the establishment of the properties and restrictions. this software analyzes the definition text for each of the more than 1,500 glossary terms (in thesaurus format), isolating those words that a thesaurus from classes (rdf:class or daml:class) and properties (rdf:property or daml:objectproperty). in the first case they proposed five classes: thesaurusobject, concept, topconcept, term, scopenote; and several properties to implement the relations, like hasscopenote (sn), isindicatedby, preferredterm, usedfor (uf), conceptrelation, broaderconcept (bt), narrowerconcept (nt), topofhierarchy (tt) and isrelatedto (rt). recently the w3c has developed the skos specification, created to define knowledge organization schemes. in the case of thesauri, skos includes specific tags, such as skos:concept, skos:scopenote (sn), skos:broader (bt), skos:narrower (nt), skos:related (rt), etc., that are equivalent to those listed in the previous paragraph. our specification does not make any statement about the formal relationship between the class of skos concept schemes and the class of owl ontologies, which will allow different design patterns to be explored for using skos in combination with owl. although any of the above-mentioned formats could be used to implement the thesaurus, given that the endproduct of our process is to be an ontology, our proposal is that the product to be generated during this phase should have a format compatible with the final ontology and with the previous taxonomy. therefore a minimal number of changes will be carried out on the product created in the previous step, resulting in a knowledge representation tool similar to a thesaurus. that tool does not need to be modified during the following (final) phase of transformation into an ontology. nevertheless, if for some reason it is necessary to have the thesaurus in one of the other formats (such as skos), it is possible to apply a simple xslt transformation to the product. another option would be to integrate a thesaurus ontology, such as the one proposed by hall,28 with the ontology representing the ieee glossary. in the thesaurus implementation carried out in our project, the following limitations have been considered: ■■ only the hierarchical relationships implemented in the taxonomy have been considered. these include relationsips of type “is-a,” that is, generalization relationships or type–subset relationships. relationships that can be included in the thesaurus marked with tt, bt, and nt, like relations of type “part of” (that is, partative relationships) have not been considered. instead of considering them as hierarchical relationships, the final ontology includes the possibility of describing classes as a union of classes. ■■ the relationships of synonymy (uf and use) used to model the cross-references in the ieee glossary (“syn” and “see,” respectively) were implemented as equivalent terms, that is, as equivalent axioms between classes (owl:equivalentclass or daml:sameclassas), with inverse properties to reflect the preference of the 202 information technology and libraries | december 2010 match the name of other glossary terms (or a word in the definition text of other glossary terms). the isolated words will then be candidates for a relationship between both of them. (figure 8 shows the candidate properties obtained from the software engineering glossary.) the user then has the option of creating relationships with the identified candidate words. the user must indicate, for every relationship to be created, the restriction type that it represents as well as existential or universal quantification or cardinality (minimum or maximum). after confirming this information, the program updates the file containing the ontology (owl or daml), adding the property to the class that represents the processed term. figure 9 shows an example of the definition of two properties and its application to the class highorderlanguage: a property express with existential quantification over the class datastructure to indicate that a language must represent at least one data structure; and a property translateto of universal type to indicate that any high-level language is translated into machine language (machinelanguage). ■■ results, conclusions, and future work the existence of ontologies of specific knowledge domains (software engineering in this case) facilitates the process of finding resources about this discipline on the semantic web and in digital libraries, as well as the reuse of learning objects of the same domain stored in repositories available on the web.30 when a new resource is indexed in a library catalog, a new record that conforms to the ontology conceptual data model may be included. it will be necessary to assign its properties according to the concept definition included in the ontology. the user may later execute semantic queries that will be run by the search system that will traverse the ontology to identify the concept in which the user was interested to launch a wider query including the resources indexed under the concept. ontologies, like the one that has been “evolved,” may also be used in an open way to index and search for resources on the web. in that case, however, semantic search engines such as swoogle (http://swoogle.umbc .edu/), are required in place of traditional syntactic search engines, such as google. the creation of a complete ontology of a knowledge domain is a complex task. in the case of the domain presented in this paper, that of software engineering, although there have been initiatives toward ontology creation that have yielded publications by renowned authors in the field,31 a complete ontology has yet to be created and published. this paper has described a process for developing a modest but complete ontology from a glossary of terminology, both in owl format and daml+oil

libraries | hilera et al. 203 to each term.) we defined 324 properties or relationships between these classes. these are based on a semiautomated linguistic analysis of the glossary content (for example, allow, convert, execute, operatewith, produces, translate, transform, utilize, workin, etc.), which will be refined in future versions. the authors’ aim is to use this ontology, which we have called ontoglose (ontology glossary software engineering), to unify the vocabulary. ontoglose will be used in a more ambitious project, whose purpose is the development of a complete ontology in software engineering from the swebok guide.32 although this paper has focused on this ontology, the method that has been described may be used to generate an ontology from any dictionary. the flexibility that owl permits for ontology description, along with its compatibility with other rdf-based metadata languages, makes possible interoperability between ontologies and between ontologies and other controlled vocabularies and allows for the building of merged representations of multiple knowledge domains. these representations may eventually be used in libraries and repositories to index and search for any kind of resource, not only those related to the original field. ■■ acknowledgments this research is co-funded by the spanish ministry of industry, tourism and commerce profit

versions will be improved by others who might take on the work. such improvements will increase the ontology’s utility, but will make it a lessfaithful representation of the ieee glossary from which

(2) what do instruction librarians perceive as the strengths and weaknesses of these tools? (3) what digital literacy gaps are instruction librarians identifying right now that may prevent access to equitable information literacy instruction online? this study will deliver and discuss findings from the survey as well as make recommendations toward best practices for utilizing technology tools and assessing them for equity and student engagement. introduction the worldwide covid-19 pandemic has had important repercussions for university libraries. all library services, including information literacy instruction, moved online in a matter of days, creating a wave of needs that required immediate response. with the closure of university campuses all around the world, academic libraries encountered an unprecedented test of their adaptation abilities. although online education has been around for many years, widespread use of the remote classroom may have been unprecedented for many librarians until the spring of 2020. this type of online learning, as charles hodges et al. explain, is significantly different from the otherwise established domains of online and distance learning because it is unplanned, rushed, and happening in the midst of a crisis.1 as they note, “emergency remote teaching has emerged as a common alternative term” to differentiate from standard online education prior to the pandemic.2 the authors recognize the different and sometimes overlapping personal and professional impacts covid-19 has had on our communities, both inside and outside of the classroom. rather than broadly assessing emergency remote teaching, the authors are looking at what jody greene, referring to teaching during the covid-19 pandemic, calls “specific technological tools and flexible teaching practices.”3 this paper is concerned with issues of equity, student engagement, kathia salomé ibacache oliva (kathia.ibacache@colorado.edu) is romance languages librarian, assistant professor, university of colorado boulder. amanda rybin koob (amanda.rybinkoob@colorado.edu) is literature and humanities librarian, assistant professor, university of colorado boulder. eric vance (eric.vance@colorado.edu) is associate professor of applied mathematics and director of lisa (laboratory for interdisciplinary statistical analysis), university of colorado boulder. © 2021. mailto:kathia.ibacache@colorado.edu mailto:amanda.rybinkoob@colorado.edu mailto:eric.vance@colorado.edu information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 2 and technology tools that could be used to facilitate library instruction during emergency remote teaching. the authors seek to answer the following questions: (1) what technology tools are academic librarians using to deliver content and engage student participation in emergency remote library sessions during covid-19?

(3) what digital literacy gaps are instruction librarians identifying since covid-19 that may prevent equitable access to information literacy instruction online? literature review technology tools facilitated a quick transition online in march 2020, enabling librarians to interact with students despite the move to emergency remote teaching. however, this fast transition and its associated learning curve accentuated issues of student engagement including equity and accessibility. there is a dearth of existing literature on teaching and learning online during times of great societal stress, with some notable exceptions, including a recent piece about university closures and moving to online classes during student-led protests in south africa from 2015 to 2017.4 as such, this literature review considers some of the barriers that contribute to inequitable information access in online learning, as well as digital literacy definitions. here we consider both ongoing challenges to equitable online access and specific challenges for the current covid-19 pandemic. barriers to equitable student access in online learning equity in academic libraries is widely represented in the scholarship through topics including disability, race, class, and salary gaps among librarians.5 however, as our ongoing pandemic illustrates, there is a strong need for more literature regarding students’ equitable online access to information during times that call for emergency remote teaching. the issue of equity may be considered in terms of external and internal challenges, which affect students differently. external barriers include low bandwidth and lack of devices. some researchers advise letting students communicate through chat instead of a webcam, since webcam use increases bandwidth consumption.6 understandably, colleges may need to provide computers and wireless hotspots to students who lack access to computers or to the internet.7 moreover, a 2018 pew fact tank publication noted that 15 percent of homes with school-age students (6–17 years old) do not have access to high-speed connection, and this digital divide particularly affects teens and their ability to be involved with homework.8 although this data focused on school-age students, these issues probably affected some college students during the pandemic. students may also be experiencing internal barriers such as language differences, lack of self regulation, lack of previous educational experience, and stress, all of which may affect academic performance. for example, one study found that language barriers challenged international students during remote web conferences with librarians.9 another study of international students showed that their academic success relied significantly on a variety of internal characteristics, such as self-regulation.10 additionally, a survey of students taking online courses showed that previous educational experience, including with online learning or within a given discipline, supported completion of those courses.11 moreover, stress is an internal barrier for students that may have external causes and is likely affecting librarians, faculty, and students during covid -19. scholars note that stress changes peoples’ use of technology, and this stress manifests differently depending on individual identity markers, such as gender and experience.12 information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 3 technology tools, digital literacy, student engagement in addition to barriers to equitable access, the digital age that has characterized the late 20th and 21st centuries, has prompted the advent of multiple technology tools that may be used in online library sessions, including emergency remote library instruction. these tools are meant to facilitate instruction and engagement, but they require students and instructors to be comfortable with technology. in the case of higher education, this level of comfort involves digital literacy competencies that surpass what is known as traditional textual literacy. the american library association’s (ala) digital literacy task force defines digital literacy as “the ability to use information and communication technologies to find, evaluate, create, and communicate information, requiring both cognitive and technical skills.”13 during the pandemic, the technical and cognitive skills of library instructors and students may be compromised due to stress as well as individual situations and specific environments. one of the technical challenges for remote library sessions stems from the need for instructor s to use tools to achieve flexibility and hybridity. librarians steven j. bell and john shank, addressing the challenges of new technologies for librarianship, coined the term “blended librarian” in 2004 to denote a librarian who combines traditional skills with those involving knowledge of hardware and software as applied in the teaching and learning process.14 the concept of the “blended librarian” may be outdated, but it encompasses the notion that librarians are expected to be comfortable with technology. again, librarians are now facing the mandate of presenting information literacy and library resources online, navigating between and facilitating the use of multiple technology tools and formats. it is worth considering how well our tools meet this mandate. although remote learning may be more amenable to some learners than others, there is consensus on the benefits of using technology for teaching and learning even if a learning curve exists for instructors. for example, researchers examining school support for classroom technology found that teachers supported enhanced technology integration even if it surpassed their own technology skills.15 notwithstanding the benefits perceived by teachers, there are also some drawbacks in the use of technology in the classroom, especially for distance learning. digital technologies researcher jesper aagaard, reporting part of a study on “technological mediation in the classroom” refers to two processes: “outside in,” where students use educational technologies to acquire knowledge in the classroom, and “inside out,” where students use technology tools to withdraw from the classroom visiting non-related websites.16 for instruction librarians, student engagement is paramount; therefore, redirecting students who leave the digital classroom is important, though it can be difficult to know when this occurs. a number of reasons could explain why students may disengage in a distance learning setting, one of them being the lack of digital literacy. moreover, the belief that higher education students in the 21st century are technologically savvy may be misleading. citing mark prensky, who originated the terms “digital native” and “digital immigrant,” wan ng explains that the phrase “digital natives” describes those people born in 1980 and after whose lives have been shaped by technology.17 ng found that while the students in his study were very comfortable with technologies such as word processor software, youtube, and facebook, they were not as comfortable using technologies to create content.18 there may be a digital literacy divide between information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 4 knowing and using a technology for social media and using a technology to create online content such as web pages and blogs. similarly, ng found that when presented with unfamiliar technology, students spent less time learning the new technology and instead focused on preparation of content.19 this finding may be of concern to instruction librarians who use a myriad of tools during emergency remote teaching. it is important to consider that these digital literacy divides could stem from factors not related to a student’s age group. researchers ellen johanna helsper and rebecca envon question the notion that a person may be called a digital native if they were born after 1980. these authors state that there are variables other than generational differences that could define a person as a digital native, such as gender, education, experience, and interaction with technology.20 therefore, even when people grow up in technological environments, they may not be considered digital natives. to minimize a gap in equity, lecture design, even for one-time library sessions, offers an opportunity to think of technology tools that could increase students’ participation and prompt learning. david ellis, studying classroom resources to enhance student engagement, notes that padlet, a web 2.0 technology, supports interaction and learning.21 seyed abdollah shahrokni, reviewing another web 2.0 technology, playposit, as a video tool for language instruction, states that it “can support learning in language classrooms” if used in a lecture design that includes relevant questions.22 lecture design applies to all types of settings: in person, flipped, and distance learning. approaches should be applied consistently to help students become more digitally literate and bridge equity issues where possible. jurgen schulte et al., providing examples of “new” librarian roles in a science curriculum, note that digital literacy enables better learning. 23 in the case of emergency remote teaching, instruction librarians may promote digital literacies through the use of technologies that increase students’ engagement and their “outside in” participation in the teaching and learning process. considering these challenges, the authors seek to identify the strengths and weaknesses of technology tools used by librarians and the digital literacy gaps that may prevent access to equitable library instruction. methods instrument the authors used a six-question qualtrics survey approved by the institutional review board at the university of colorado boulder. the survey was open for two weeks, between may 10 and may 24, 2020. it is worth noting that the questions were specific to this timeframe, and some responses indicated that instruction librarians were still finishing up spring semester 2020. the survey received 202 responses. however, the number of responses to each question varied as answers were not required. the data collected were both quantitative and qualitative, reflecting respondents’ practices, perceptions, and personal knowledge. respondents answered two multiple-choice and four free-text questions. for the multiple-choice questions, participants could choose all the options that applied and enter their own choice as well. the multiple-choice questions gathered data on the technology tools that librarians used to deliver content or to engage with students during covid-19. these questions distinguished between content delivery platforms (like zoom) and technology tools used for student engagement (like padlet). the technology tools included in the multiple-choice questions were chosen based on the authors’ knowledge of their potential relevance to instruction librarians. the information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 5 final four qualitative questions collected information about respondents’ perceptions of strengths and weaknesses of technology tools, as well as digital literacy gaps identified during covid -19 and other challenges to equitable instruction. qualtrics provided a report, which the authors organized in a spreadsheet used to analyze the data and create the figures. the following survey questions were asked: 1. what content delivery technology have you used to create your distance learning library sessions during covid-19? 2. what technology tools have you used to enhance student engagement in your distance learning library sessions during covid-19? 3. what are the strengths of the technology tools you’re using right now? 4. what are the weaknesses of the technology tools you’re using right now? 5. what digital literacy gaps have you identified in your students since covid-19 closures? ala’s digital literacy task force defines digital literacy as “the ability to use information and communication technologies to find, evaluate, create, and communicate information, requiring both cognitive and technical skills.” 6. what other challenges exist in your ability to effectively provide equitable information literacy instruction during this time? please see appendix a for the complete survey instrument. participants the survey was distributed through email to five listservs associated with academic libraries and library organizations: the seminar on the acquisition of latin american library materials (salalm) listserv, information literacy instruction discussion listserv, the library instruction roundtable (lita) listserv, the lita instructional technologies interest group listserv, and the literature in english discussion list. these organizations were chosen due to their connection with library instruction in academic libraries and the authors’ subject specialty affiliations (romance languages and english and american literature). grounded theory approach the data for questions 3, 4, 5, and 6 were analyzed using a basic grounded theory approach, where the authors collected themes and patterns from the responses rather than approaching the data with pre-existing hypotheses.24 based on their observations, the authors categorized responses according to an agreed-upon set of keywords. in addition, after coding the data separately, the researchers examined every answer together to ensure consistency and reliability. a mixedmethods survey with a grounded theory approach to analysis allowed for a larger number of responses than qualitative interviews. the survey format also allowed for quicker solicitation and analysis of data, given the urgency of the topic and the authors’ desire to provide recommendations to colleagues in a timely manner. findings popularity of technology tools figure 1 shows respondent selections from the list of content delivery tools provided by the authors. a large number of respondents used libguides as a content delivery tool during covid 19, followed closely by the video conferencing tool zoom. however, although libguides and zoom displayed a substantial amount of concurrence among the respondents, fewer than half of the https://lists.ala.org/sympa/info/ili-l https://lists.ala.org/sympa/info/lirt-l https://lists.ala.org/sympa/info/lirt-l https://lists.ala.org/sympa/info/lita-insttechig https://lists.ala.org/sympa/info/les-l information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 6 respondents used the rest of the technology tools shown in figure 1. these data suggest that a large number of the respondents were able to deliver library instruction via synchronous learning through zoom or by providing resources asynchronously via libguides, and thus had the opportunity to have at least some engagement with students. figure 1 also shows that more respondents used snagit and screencast-o-matic to create videos than playposit. similarly, a little over one-eighth of respondents used the graphic design tool canva to create content, although this tool had better usage than adobe illustrator, which was only used by one respondent. in addition, the communication software google hangouts was largely not used by respondents. the authors listed formative and pear deck in the survey options as well, but these were not selected by any respondents (not shown in figure 1). figure 1. respondent selections to question 1: what content delivery technology have you used to create your distance learning library sessions during covid-19? figure 2 represents the tools used by the 95 respondents who selected other and entered additional tools in a free-text box in question 1. tools mentioned, such as webex, camtasia, panopto, and kaltura capture, were used for video conferencing but to a lesser extent than zoom. similarly, only six respondents reported using narrated powerpoint. interestingly these tools were still used by more people than playposit. respondents mentioned a wide array of other technology tools in the free-text box (see appendix b); however, none of these tools were used individually by more than three respondents. information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 7 figure 2. other content delivery technology used to create distance learning library sessions during covid-19. the survey also asked about technology tools used for student engagement in distance learning library sessions during covid-19. the authors distinguish these tools from content delivery tools, as they are often utilized in conjunction with some of the tools mentioned in figure 1 to facilitate student interaction. figure 3 shows that, among the tools listed by the authors, respondents preferred the application google forms, found in google drive and google classroom, as more than one-third of respondents indicated they used this application to enhance student engagement. although representing fewer than half of the respondents, 18 more people selected google forms over poll everywhere, the tool with the second-best representation. moreover, poll everywhere and padlet, two online tools that enable student participation through custom-made polls and post-it boards, were each utilized by about one-fourth of participants. the game-based learning platform kahoot was used by nearly one-fifth of respondents, and mentimeter, another interactive platform allowing students to answer multiple-choice and openended questions, was used by 11 respondents. less than five percent of the respondents used the interactive technology tools flipgrid, answergarden, jamboard, mural, slido, and socrative. no respondents indicated they used pear deck, google drawings, quizalize, gosoapbox, and yo teach! (not shown in figure 3). in addition, 42 respondents entered the names of technology tools they used to enhance student engagement in the other free-text option. similar to the responses in the free-text answer for question 1, respondents provided a broad list of technology tools. two of the tools listed displayed a higher number of concurrences: eight respondents mentioned zoom polls and four mentioned information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 8 springshare libwizard. an additional 20 tools were used by just one participant each (see appendix c). figure 3. respondent selections to question 2: what technology tools have you used to enhance student engagement in your distance learning library sessions during covid-19? strengths and weaknesses of technology tools instruction librarians also described the perceived strengths of the technology tools they used. figure 4 shows that a little less than half of the respondents agreed “easy to use” was an important consideration for technology tools, making it the most frequently mentioned strength. responses showed interest in ease of use for librarians, students, and faculty alike. for example, respondents included the phrases “our learners were comfortable with them,” “it’s easy to get started,” and “everyone already knows zoom.” in addition, nearly one-fourth of participants selected the strength “interactive/collaborative” followed at a distance by the strength “flexible,” which dropped dramatically to 15 percent. in fact, the number of respondents who noted “interactive/collaborative” was almost quadruple the number of respondents who mentioned the less popular choices “supported by it” or “captioning functionality.” fewer than 19 participants acknowledged that it was important for the technology tools to enable remote instruction, include recording functionality and screen-sharing functionality, and to be able to enhance communication. only 11 participants wrote that it was important for the tool to be readily available. respondents referred to other strengths not included in figure 4 due to their infrequency. nonetheless, some of these strengths offer unique insights. for example, four respondents noted information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 9 that they favor free tools. in addition, three respondents stated that it was beneficial to repurpose content created with technology tools. two respondents mentioned that they preferred tools that do not require download and/or account creation. another respondent mentioned that mo bilefriendly tools were most helpful for engaging students. figure 4. respondent answers to question 3: what are the strengths of the technology tools you’re using right now? respondents also shared their observations around technology tool weaknesses. figure 5 shows that several perceived weaknesses were the inverse of strengths from figure 4, including that tools were “difficult to use” or “not interactive or engaging.” figure 5 also indicates that respondents were divided as to the most significant weaknesses. in fact, not even one-fourth of respondents selected the most frequent response, “not interacting or engaging,” displaying a lack of concurrence. the second most-repeated weakness referred to bandwidth requirements, with 27 respondents worrying about the lack of requisite internet access. the authors joined together seven weaknesses mentioned by respondents as “other functional limitations.” these weaknesses included “lack of screen capture,” “connection failures,” “lack of captioning,” “lack of recording capabilities,” “limited sharing screen,” “freezing video,” and “video quality.” each of these specific limitations was only mentioned a couple of times, but together these functional limitations were mentioned by 17 respondents. again, there were some specific weaknesses mentioned by only a few respondents. some of the highlights included tech overload or too many tools to choose from (two respondents), computer storage requirements (three respondents), and that the tools are not flexible enough or easy to information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 10 integrate into other systems such as canvas or libguides (four respondents). two people observed that the tech tools they used had no weaknesses. interestingly, 18 respondents included keywords and phrases in their answers (not shown in figure 4) that were not directly related to tool weaknesses, but rather described other issues affecting teaching and learning in a remote setting. these included students lacking computer s or having only cell phones (seven respondents), students’ limited technology skills or attitudes about remote learning (six respondents), students’ home setups (three respondents), and limited familiarity with the tools among teaching faculty (two respondents). these kinds of responses illustrate the wide range of interconnected factors impacting librarians’ experiences engaging with students and technology during covid-19. finally, 26 percent of librarians answering this question mentioned some weaknesses related to zoom (not shown in figure 5). to illustrate, some comments included “active learning in zoom [sic] is difficult . . .”; “zoom recordings take up a lot of space and our college is running out of room . . .”; “zoom doesn’t work as well when using wifi [sic], as opposed to connecting through a network”; “it is easy to zone out and not pay attention to zoom [sic]”; “with zoom it is difficult to interact with students on a one-to-one basis as they breakout [sic] to conduct research”; and “students tend to not have cameras on . . . and it’s hard to tell if they are actually paying attention.” these observations may show that while respondents favor using tools like zoom, they are also aware of important limitations. figure 5. respondent answers to question 4: what are the weaknesses of the technology tools you’re using right now? information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 11 digital literacy gaps beyond describing the technology tools used, respondents were asked to identify digital literacy gaps that they noticed in students during covid-19 closures. as stated above, the authors defined digital literacy in the survey question according to the ala digital literacy task force definition. still, answers to this question provoked a wide range of responses as seen in figure 6. the most frequently recurring response was that digital literacy gaps were the same as those perceived before the pandemic, although only 25 respondents agreed on this. digital literacy gaps observed by respondents included “lack of tech skills in general,” “problems evaluating information online,” “ineffective search strategies,” “difficulty communicating online,” “problems using library resources in general,” “problems using online resources,” “problems using library databases,” and “understanding citation and plagiarism.” the second-biggest category, “lack of tech skills in general,” included varied responses such as “some of my students lack a basic understanding of . . . browsers, upload/download, url versus link, activate/enable a feature etc.”; “students have trouble navigating multiple windows”; and “students are having a hard time trying something new which involves more than a single click or two.” eleven other respondents noted that it was too early to evaluate digital literacy gaps during emergency remote teaching. one respondent offered insight about the possibility that librarians missed gaps because they were not able to meet with all students. as they stated, “students who have access and are in contact with librarians seem to have adequate skills. i don’t know how many students simply lack internet access, and i don’t know how many need the library and don’t figure out how to access it. . . .” ideas for reaching more students who may not have access to in-class library sessions are mentioned in the recommendations section below. when asked about digital literacy gaps, some respondents mentioned student experiences during covid-19 that were not directly related to digital literacy and therefore are not included in figure 6. however, the authors considered this information relevant because it provided insight into perceived challenges students faced. the authors separated such responses into two g roups: external challenges and internal challenges. external challenges mostly involved technology access rather than digital literacy per se, with 22 respondents mentioning lack of tech access as a barrier or gap. it is worth noting that respondents mentioned this lack more than any individual digital literacy gap shown in figure 6. fifteen respondents also noted that students may lack internet access at home, while five percent mentioned a home environment that was not ideal or conducive to learning. although these external challenges are not explicitly related to digital literacy, the fact that they are mentioned here may indicate that respondents perceived these challenges as interrelated during the covid-19 pandemic. internal challenges included concepts that may be seen as related to digital literacy but are not explicitly included in the ala task force definition. in fact, many of these challenges had to do with pandemic-specific difficulties such as “emotional issues” arising during covid-19 (10 respondents). five respondents worried about information overload, while two respondents each mentioned that students were less likely to ask for help and more likely to have problems following directions during emergency remote learning. information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 12 figure 6. respondent answers to question 5: what digital literacy gaps have you identified in your students since covid-19 closures? the last survey question asked respondents to reflect on any other challenges that may have impacted their ability to effectively provide equitable library instruction during emergency remote learning. figure 7 displays an array of responses, including some related to technology tools, home environments, and institutional support. nonetheless, technology access from home was perceived as the most important challenge (39 respondents) followed closely by internet issues (35 respondents). for both challenges, the authors included responses that specified lack of tech access for students, teaching faculty, or instruction librarians. many respondents d id not specify who lacked access. however, one could argue that lack of access by any of those three groups may impede connection and student engagement. other challenges such as home environment, fewer library instruction sessions, communication barriers with students, lack of student engagement, no time to plan, emotional distress, and issues with synchronous or asynchronous instruction affected 11 percent or less of respondents each. additionally, the data indicated that librarians perceived more communication barriers with students (14 respondents) than with faculty (nine respondents). in figure 7, “asynchronous/synchronous” refers to problems encountered by respondents that had to do, in general, with the unique challenges of presenting content online either asynchronously or synchronously. for example, respondents mentioned being unsure whether students were engaging with asynchronous content. they also mentioned being asked by faculty to use one format over another, despite librarian preferences. one respondent focused specifically information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 13 on the need for flexibility when addressing equity: “asynchronous instruction does not allow the real time adaptation to student needs (cognitive and technical).” even though figure 7 relates to challenges experienced in providing equitable library instruction, respondents showed that there was also an emotional factor surrounding these challenges . two revealing responses to the question about challenges included “my kids running around in the background, not having an actual office, being expected to work 40 hours a week while homeschooling and running a household” and “some students [are] more or less in shock from the pandemic; some students have illness in the family; some students have economic issues, some students just don’t learn well with online learning only.” other comments stated personal challenges, such as the “stress of living in [the] epicenter of [a] global pandemic” and “my own mental and emotional capacity.” figure 7. respondent answers to question 6: what other challenges exist in your ability to effectively provide equitable information literacy instruction during this time? because there was often little consensus among responses, the authors created word clouds for all four qualitative questions (figure 8). each of these questions showed students at the center of instruction librarians’ responses, which is not surprising given their roles and the subject of this survey. the purpose of emergency remote teaching and learning is, at its core, to continue to connect students with resources and to engage them in their learning, even and especially when it is challenging to do so. still, it is meaningful to see students at the heart of these data. information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 14 figure 8. word cloud visualization for each qualitative question answer set. challenges and limitations many of the challenges encountered while analyzing data had to do with creating meaningful keyword codes for the qualitative survey questions. this coding was challenging because respondents expressed varied experiences and opinions and there was no significant consensus regarding tools used, tool weaknesses, digital literacy gaps, or other challenges. in contrast, respondents frequently referred to students’ lack of technology and internet access, even when the question at hand did not explicitly address this. these challenges speak both to the varied experiences of and institutional responses to covid-19, as well as perceived lack of tech or internet access among students as a primary barrier to effective emergency remote teaching. further, while some questions signaled a clear answer, others required interpretation. to illustrate, respondents used the term “accessibility” inconsistently. some respondents used this term to refer to accessibility for students with disabilities, and others used it to refer to “availability.” therefore, the authors employed contextual clues to determine meaning. regardless, if the meaning remained unclear, then these answers were not considered for coding. similarly, respondents didn’t always use the same language to describe the same concepts. for example, a participant noted that “the technology we have is limited to lecturing and answering questions and providing documents and videos online. we don’t have polls enabled . . . .” the information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 15 authors interpreted this to mean that the technology tools didn’t allow for robust engagement with students, though the respondent didn’t specifically mention the word “engagement.” again, if context or meaning was unclear, those responses were not coded. another challenge occurred in analyzing responses to question 6: what digital literacy gaps have you identified in your students since covid-19 closure? some respondents appeared to be unfamiliar with the term “digital literacy,” even though a definition was provided within the question. some respondents referred to hardware access, home environment, tech access, or psychological stress rather than explicitly reflecting on digital literacy gaps as included in ala ’s task force definition. these responses could indicate either confusion around the definition of digital literacy or, as suggested above, the perception of all these factors being codependent or interrelated. limitations of the study included the design of the survey itself. for example, respondents received a list of tools for questions 1 and 2, which may have meant that they were more likely to select these than to remember other tools that they used and add them to the other category accordingly. questions 3 through 6, in contrast, did not include any multiple-choice options, which may have limited the thoroughness of responses. for example, the average number of responses to question 3 was 2.08 strengths mentioned per respondent. we think it is likely that respondents would have indicated more strengths had they been presented with a list rather than only a freetext box. the authors also did not define the difference between content delivery tools and tools for student engagement in the survey. for this reason, there was some overlap noted in the responses for questions 1 and 2. also, respondents mentioned tools for engagement that were sometimes features of content delivery tools, such as webex whiteboards and lms discussion forums. the vast landscape of tools used meant that our survey could not account for all possible manifestations of technology for content delivery and student engagement. discussion questions 1 and 2: technology tools instruction librarians are using to deliver content and engage students the instruction librarians that answered the survey have widely used technology tools such as libguides and zoom in their library seminars during covid-19. however, as data show, librarians have also used many other technology tools to create and deliver emergency remote library sessions during covid-19, due perhaps to the wide array of tools available. while libguides and zoom exhibit a high percentage of usage, this result was expected because libguides is a wellknown tool used by academic librarians and, according to the company, zoom became more prominent as a tool during covid-19.25 the relatively low usage of adobe illustrator is also somewhat predictable because this tool not only requires a subscription, but also may have a higher learning curve than other free graphic editor and design programs. data raised some further questions about the role of information technology (it) departments. are instruction librarians reaching out to their respective universities’ it departments to learn about technology tools available to them and vice versa? are it offices willing and able to provide training via video conferencing if in-person training is not available due to the pandemic? do it departments offer enough promotion to advertise these tools? these questions are not addressed in this manuscript but are important avenues for further research. only six percent of respondents information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 16 recorded “supported by it” as a strength of the technology tools they were using. this shallow percentage may appear striking but could be understood under the premise that as the pandemic set in across the united states and instruction librarians rushed to prepare and present online sessions, librarians relied on the tools that were most familiar to them instead of learning a new technology tool. the data from this survey would seem to corroborate this, as so many respondents chose “ease of use” as an important strength. one interesting detail that is worth addressing about the tools is that respondents mentioned other more than they selected the options the authors provided, which may imply that either the authors did not include the most-used tools or that the number and/or variety of tools is so wide that it is difficult to reach a consensus. one wonders if the tools mentioned in other had been included as part of the listed options, the number of respondents using these tools would be higher. questions 3 and 4: the strengths and weaknesses of tools as they affect student engagement the authors wanted to know what tools respondents had used to enhance student engagement. data show that google forms is the tool that most of the respondents have used for this purpose. however, fewer respondents used tools that are purposely designed to increase interaction in online sessions, such as kahoot and mentimeter, which do not even require a fee for using their basic features. respondents’ perceptions of the strengths and weaknesses of tools they have used provided useful information. in terms of tools strengthening student engagement, the responses were not as conclusive, as 40 of 150 respondents found these tools interactive or collaborative, and an even lower number of these respondents thought of these tools as flexible or helpful to enable remote instruction. one could argue that ada capabilities are features that may facilitate student engagement. however, when respondents were asked about the strengths of technology tools they had used, accessibility was not often mentioned as a strength. moreover, data showed that only eight respondents referred to ada problems and three of them voiced concern over captioning capabilities, which is considered a relevant ada feature. there was no mention of alt text for images, screen-readable and software-neutral file formats, or the importance of user ability to change the color and font setting in their devices to see the content. in fact, only three respondents specifically mentioned issues with videos in terms of their audio quality, lack of auto closed-captioning, and freezing images. respondents noted wide-ranging effects of tool weaknesses on both instruction librarians and students. to illustrate, the weaknesses “time intensive,” “not designed for teaching,” and “no feedback or assessment” likely affected instruction librarians at a personal level as they prepared for and assessed their teaching. in contrast, the weaknesses “ada problems,” “not interactive or engaging,” “difficult to use,” and “makes communication difficult” might primarily impact students. other concerns respondents stated that may influence student engagement included poor bandwidth, which affects internet access and causes connection issues. for example, even if librarians try to improve the video quality in zoom by disabling the higher definition option, or start a session with audio conferencing only, which will decrease the amount of bandwidth needed, students with poor bandwidth may still not be able to engage. therefore, in situations of emergency remote learning, if students lack bandwidth or an appropriate home environment, learning and engaging may become a challenge. information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 17 questions 5 and 6: digital literacy gaps and equitable instruction a number of factors affect the ability to provide equitable library instruction on the librarian side and to engage with equitable library instruction on the students’ side. one of these factors is home environment, including access to computers, good bandwidth, or an appropriate working station. our data specify that 15 respondents perceived “home environment” as a challenge when providing equitable library instruction. in addition, some respondents noticed home environment issues when asked about digital literacy gaps in relation to shared spaces and lack of computers and access. it’s possible that equity issues increased during the covid-19 shutdown, which raises the question of whether there is a correlation between the issues affecting students, librarians, and faculty. data showed that of 139 participants, a little over one-fourth of them considered “tech access from home” and “internet issues” as challenges in the ability to provide equitable library instruction. these challenges, along with “emotional issues,” were perceived to affect not only students but also librarians and faculty. although responses recorded librarians’ perceptions on equity issues, often including their own experiences, data revealed that respondents presumed faculty and students were having similar issues. data also exhibited that respondents perceived other challenges, such as “fewer library sessions” and “student lack of engagement,” that may affect students directly. fewer library sessions are a challenge that may be further addressed forthwith. however, students’ lack of engagement is a difficulty that may require thoughtful outreach, collaboration with mental health offices at the campus level, and reflective and inclusive lecture design. these challenges may have a negative impact on receiving an equitable learning experience. in fact, less commonly acknowledged gaps may, in some ways, be more important than those frequently mentioned. a well-known gap can be addressed because there is consensus that the gap exists and poses a barrier to equity in education. unnoticed or overlooked gaps, in contrast, are more difficult to address but may be no less important as barriers to equitable education. equity issues may also arise as a result of lack of digital literacy skills in students. students with higher digital literacy are deemed to perform better in an emergency remote library instruction setting, may be more prone to stay in tune and engaged with the lesson, and have less emotional stress by feeling confident. however, as wan ng explains above, those recognized as digital natives may not necessarily have digital literacy, even if they are comfortable with social media tools.26 data do not tell us the age of students; regardless, digital literacy gaps were detected by respondents. these perceived gaps in digital literacies (evaluating information, communicating online, applying search strategies, using library resources and databases, understanding plagiarism and citation, and using online resources) are important for librarians to address during emergency remote learning. last, the lack of consensus may be explained by the complexity of the concept of digital literacy. it is possible that many of these gaps existed before, but librarians recognized them as new during emergency remote learning. one response illustrates this idea: “the closure has prompted many more students to request help in every step of the digital literacy process. i’m not sure if students typically ask each other, or their professors/instructors. regardless, it’s exposed that not all students know things i’d assumed they did.” whether these gaps are new or not remains unclear, as evidenced by another respondent who stated, “nothing new to the covid era.” information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 18 recommendations these recommendations seek to address some of the issues that arose in the data, especially those regarding equity and emergency remote library instruction. to illustrate, one respondent summed up the current situation while also posing a question that appears valuable: “not all of our students have the same access to stable technology and internet, nor do they all respond to online teaching strategies in the same ways. how do we create equitable and accessible learning opportunities?” while the authors do not have all the answers, based on the analysis of the data and emerging themes, some recommendations may help instruction librarians move forward through the covid-19 crisis. technology and equity the authors realize that a budget is essential for the implementation of recommendations that may reduce both inequitable access to information and lack of digital literacy. nonetheless, the recommendations below intend to offer guidance on ways to improve equitable access, digital literacy, and student engagement during emergency remote library sessions. one external digital barrier for students engaging in emergency remote library sessions was the lack of equipment at home, possibly due to economic hardship. university libraries could provide kits containing a chromebook, webcam, microphone, wi-fi hotspot, and headphones to increase equitable access. access to this equipment may help students feel supported and understood, with a sense of dignity. these offerings should be in coordination with other campus units who may provide similar services, such as student affairs and it departments. likewise, a coordinated marketing and outreach effort at the campus level may enhance the visibility of equipment available for student use. as stated above, “ease of use” rose to the top as the most-frequently mentioned technology tool strength, which is understandable given the many stressors educators and students may be experiencing during covid-19. however, it is important to keep in mind that tools should be “easy to use” not just for librarians and teaching faculty, but especially for students. nonetheless, given the difficulty of assessing instructional technology and library information literacy sessions right now, it is challenging to know whether students find the technology tools that librarians choose truly “easy to use.” compounding the perception that tools are easy to use is the possibility that tools may not be ada accessible. though the survey did not ask about accessibility explicitly, and while the authors did not vet the tools listed in the survey for their accessibility features, the authors wonder how many tools are fully accessible to all learners. instead of choosing tools for their perceived ease of use, a further recommendation is to move beyond valuing what’s easy to critically reflect on whether tools are fully accessible to students with visual or hearing impairments or learning differences. if the answer is no or unclear, perhaps using basic content delivery tools that are vetted for accessibility features is the better option. it is recommended to follow best practices for using those tools (for example, by referring to guidance from campus it departments). if instruction librarians consider themselves “blended,” or perhaps even so well-versed in technology that a term like “blended librarian” is no longer needed, they should also prioritize flexible, responsive, and intentional use of technology in their lecture design. if a tool that they assumed would be easy to use for all students is proving challenging for some, librarians should have alternative options and extra support at the ready. they may also ask themselves whether information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 19 use of a technology tool furthers the learning process and outcomes of the course, or if technology is added for its own sake. in addition, avoiding use of extra tools and technology that does not genuinely enhance lecture goals and priorities may help students avoid stress related to technology, which could further students’ emotional well-being during this fraught time. being clear with students about which tools will be used and for what purpose may help students who would otherwise struggle with layered content delivery and engagement tools. a glossary of these tools, along with when and how they’ll be used and links to technical support, could be a helpful support document for students. communication and equity it is worth exploring librarian, student, and faculty communication not explicitly focused on technology. some respondents mentioned outreach and connection challenges that have less to do with technology and more to do with other stressors and limitations. for example, some librarians reported receiving fewer requests for information literacy sessions or library support than usual, and some speculated that this was because of the quick move to emergency remote learning, lack of time to plan, and the possibility that a library session was “extra” and faculty were trying to simplify. there are several ways to address this challenge. librarians can attempt to meet students and faculty where they are by offering multimodal learning opportunities, including both synchronous and asynchronous offerings (zoom meetings, prerecorded videos, tutorials/quizzes, canvas discussion posts, and libguides are a few options). it is also paramount to make sure librarians are reachable at the point-of-need, which may mean extended weekend and evening hours on the virtual ask-a-librarian desk. also imperative is ensuring that virtual services, as well as consultation request links and/or email addresses, are clear and visible to students and faculty on the library’s website. some survey respondents mentioned that communication with faculty was difficult, and this may have contributed to fewer instruction requests. while it is understandable that faculty may have been less responsive to librarian outreach for a variety of reasons, there are some ways to encourage faculty communications. for example, librarians could provide simple, bulleted lists with updated information on services and offerings, individual attention (focused on specific classes and topics), and options, acknowledging that some faculty will simply not want to share classroom time during emergency remote teaching. librarians can also work to bridge the disconnect between it and their departments by proactively reaching out to learn about best practices not only for technology use, but also for ada accommodations. even when information literacy sessions are requested, faculty may not always share student accommodation needs. librarians can ask for help from it or other units on campus (such as centers for teaching and learning) to make sure that their communication techniques are aligned with inclusive, user-centered approaches to teaching and learning with technology. as professionals in a unique role serving both students and faculty, librarians may also check in on a person-to-person basis with both groups. acknowledging that we are people with mental and physical health needs working together in difficult circumstances is one way of connecting with students and faculty in an authentic way. emergency remote teaching and learning is different information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 20 from typical remote or online learning and being clear about that might also help everyone adjust expectations and extend compassion. professional development and personal support while emergency remote teaching and learning may not seem like the best time for professional development, it is important to acknowledge that librarians deserve support in navigating this unprecedented time. even as we clearly want to help students who may be especially vulnerable during covid-19, there is a sense of being overwhelmed, and librarians may not always know where to start. while there are online webinars and discussions that provide advice about how to best help students during covid-19, the authors recommend a more specific approach targeting digital literacy gaps and support systems for librarians. in reviewing survey responses to perceived digital literacy gaps and other challenges, it became clear that not all librarians are well-versed in digital literacy concepts. if librarians have time to take one approach to professional development as it relates to instruction and information literacy, the authors recommend learning more about digital literacy competencies and thinking critically about how emergency remote library instruction design can address those competencies and potential gaps. of course, stresses of the pandemic are impacting librarians as well as faculty and students. it is important that we connect with colleagues and support systems during this time. one option might be to form a community with colleagues to determine best practices for use of technology in instruction among other relevant topics (examples at the authors’ library include anti-racist actions and a caregiver’s support group). librarians should also prioritize their own health (mental and physical) and stress management. the recommendations are everywhere but bear repeating: connect with family and friends, exercise, take time away from the computer, and make sure to rest. librarians should be kind to themselves and their colleagues and offer or ask for support when needed. conclusion as of spring 2021, the covid-19 pandemic is not yet over. it remains unclear whether and when academic library instruction will return to the old normal. the data collected and analyzed during this paper, as well as the discussion and recommendations, can inform how instruction librarians respond to student needs and challenges as everyone continues to cope with life during emergency remote learning. especially compelling are the data shared about the strengths and weaknesses of technology tools used to enhance student engagement in library instruction. these data provide parameters that may help other instruction librarians make decisions when choosing a technology tool and be prepared to troubleshoot when issues arise. a concerning data revealed that digital literacy, as defined by ala’s digital literacy task force, is a subject that may not be widely understood by instructors. although our pool of respondents was small, instruction librarians may need a broader understanding of what digital literacies look like in practice when dealing with emergency remote teaching and a diverse student population. while instruction librarians’ experiences and perceptions are one important piece of the puzzle, especially in acknowledging shared challenges, it is important to recognize that students may have needs, digital literacy or otherwise, that educators are missing. though assessment is difficult right now, reflection and attention to the whole student experience is necessary. working with colleagues on campus to provide technology, including laptop computers and wi-fi hotspots, as information technology and libraries june 2021 emergency remote library instruction and tech tools | ibacache, rybin koob, and vance 21 well as evaluating our content delivery and engagement tech tools for ada accessibility, are examples of ways that instruction librarians can connect students with unmet needs to resources during this difficult time. examining instruction librarians’ ongoing response to the pandemic, while challenging, will help libraries become more emergency-responsive and better able to meet the needs of diverse students in the 21st century. acknowledgement we would like to thank moria woodruff from the university of colorado boulder writing center for her help revising this manuscript. information technology

'~> the paper is based on a clr fellowship report to the council on library resources, inc., for the period january-june 1972. 6 journal of lihra1·y automation vol. 7/1 march 1974 2. effect of high level administrative changes.-in a few instances, the library automation effort was instigated by the president of the institution. he could, in effect, personally direct the allocation of resources. however, whenever a high administrative official leaves, the resulting vacuum is quickly filled by other interests, the atmosphere changes, and his personal program goals dissolve. 3. management inadequacies.-the effects of domination by a technician or special interest group are described below in more detail. although more and more organizations are putting together influential user groups to point the way toward better management, decision-making responsibility and authority continued to be misplaced in a few institutions which vested authority for technical decisions in a committee of deans who were somewhat remote from current trends in computing because of their administrative responsibilities. (in one institution, it was half jokingly stated that a dean in any hard science could be characterized as suffering from a minimum technological time lag of two years.) 4. lack of long-range planning inclusive of attention to community priorities.-few facilities visited had any written long-range plans, either for the acquisition of hardware, the conversion of older programs, or the involvement of users in systems design. ad hoc arrangements were prevalent. 5. system instability.-this was more the rule than the exception, especially in software, operating systems, hardware configuration, and pricing. wherever an academic computing facility was used for library development, the same broken record always seemed to be playing: the facility was always being taken apart and put together again. of course library development was not the only user affected; complaints arose from all users. 6. biased pricing algorithms.-in the academic facility, student and research use were competitive. hence systems were typically geared to distribute computing resources around the clock in some equitable and rational way. for instance, short student jobs were sometimes given a high priority for rapid turnaround, while long, grinding calculation work was pushed off to the evening or night shift by means of variable pricing schedules or algorithms. a pricing algorithm is basically a load leveling device to smooth out the peaks of over-demand and the valleys of under-utilization which would have occurred in the absence of such controls. devising pricing algorithms is by no means a simple task, since many factors must be taken into account: the kinds of machine resources available, their respective costs, the data rates at which they can function, market demand, hardware and software available, and system overhead, to name but a few. library jobs tended to suffer in both batch and on-line processing. in the former case, because batch jobs on large data bases took so much institutional political and fiscal factors/veaner 7 time, library work generally could not be done during the prime shift; in the latter case, an on-line library system made substantial demands upon a facility's storage equipment and telecommunications support, and competed with all other on-line users. 7. sense of competition with the library for hard dollars.-this problem, which is related to pricing bias, is detailed further on page 21. 8. scheduling problems.-many of the institutions visited had systems or charts for scheduling production, development, and maintenance. but conversations with system users often verified that schedules were either not met or had been unrealistically established. this was especially the case with development work b. personnel in the computer facility 1. selection and evaluation.-inasmuch as the library often did not have the competence to judge personnel nor the ability to generate meaningful specifications, there was generally very little protection from incompetence in this area. 2. elitism: the notion that the masters of the computer are inherently superior to and have better judgment than computer customers.-elitism is a paradox: it can be positive or negative-positive when the best brains produce software designs of true genius with respect to function, performance, economy, and reliability-but in its negative manifestation, reminiscent of the girl with the curl in the middle of her forehead: "when she was good, she was very, very good; when she was bad, she was horrid." during the boom years when computer facilities were expanding faster than the supply of competent staff, elitism seemed fairly common in the computer center. the excitement of rapid development, the seemingly unlimited intellectual challenge presented by the powerful apparatus, and high strung dispositions sometimes caused tempers to flare or immaturity to sustain itself beyond a reasonable time. strange hours, strange habits, bizarre behavior, all seemed to conspire against ordered and rational development. fortunately, as the field matures, the negative aspects of elitism are dying; managers now can concentrate on staff development work to turn top intellectual talents toward productive achievement. 3. disinterest.-this factor may be allied to elitism. in some instances, the computer center's staff gave considerable attention to the library during the period immediately following machine installation, when utilization was low. later, the staff's keen interest became "dulled" at the thought of operating a production system. "more interesting jobs" were .challenging the programmers and beginning to fill up the machine. 4. fear of the unknown big user.-it was recognized early that the library could be among the computer facility's largest potential customers, perhaps the largest. in some facilities, this recognition may have induced 8 journal of library automation vol. 7/1 march 1974 a fear of being taken over or overwhelmed by the user, who would then be in a position to dominate and dictate the direction of further development and operations. 5. fears of an unknown production environment-simply expressed, a production environment removes much of the stimulus for creative approaches to problem solving unless continuous development is maintained for new systems and new applications. many of the best programmers did not wish to lose their freedom to innovate and actively resisted participation in establishment of a production environment, with its concomitant requirement of "dull" maintenance support work. c. deficiencies within the library environment 1. failure to understand in full detail the current manual system.even where the manual system was understood, there was often an inability to describe it in the clear, unambiguous style essential to system design work. these deficiencies were further compounded by the unwillingness of some librarians to learn how to communicate adequately with computer personnel. 2. inability to communicate design specification.-many did not understand how to put together a specification document; particularly they did not know how to account exhaustively for all possible cases or alternatives. librarians were unaccustomed to defining their data processing requirements quantitatively or with precision-both absolutely indispensable to the computer environment. also, as much as the computer facility changed its software environment, many library development efforts were constantly changing their system requirements-a condition which made it all but impossible to program efficiently. 3. failure to understand the development process.-development is a new phenomenon in libraries. most librarians were not educated to comprehend development as an iterative process, characterized by experimentation, error, feedback, and corrective measures. accustomed to the relative stability of long-established procedures-some of which had stood for generations, even centuries-some librarians were baffled by the rapidly changing new technology, others showed impatience and a low tolerance for frustration. many expected development projects to resemble turnkey operations, and the failure of the process to accommodate these expectations produced disappointment and an inability to cope with the computer environment. 4. failure to recognize the computer as a finite resource.-both librarians and early facility managers seemed to look upon the computer as an inexhaustible resource, the former through lack of sophistication and the latter apparently through myopia or possibly ambition. some managers must have told their users that there was "no way" their equipment could be saturated in the foreseeable future. apparently some library users were naive enough to believe. institutional political and fiscal factorsjveaner 9 5. excessive or unrealistic performance expectations.-few library users understood the relationship between the system specifications and functional results, and fewer still understood the significance of performance specifications. the situation was not assisted by notions of "instantaneous" retrieval pushed by salesmen or the popular press. (the writer recalls vividly how one salesman told him the library could have a crt device for $1 a day! and indeed, the device itself was $1 per day if one cared to do without the keyboard, without cables, installation, control units, teleprocessing overhead, a computer, software, etc.) 6. lack of an established tradition of research and development ( r & d) and the lack of venture capital in the library community.the challenge of the computer may have been largely responsible for activating research and development as a serious and continuous effort in librarianship. inexperience in raising and managing funds for r & d, as well as a general lack of knowledge of computer cost factors inhibited progress or tended to make the development effort inefficient and full of surprises. 7. human problems.-some libraries having prior experience with small batch systems underestimated the scale of effort for contributing to the design of the large system, selling it to the users, installing it, and training the users. 8. insufficient support from top management.-in some instances, library management did not accord the automation effort the kind and degree of support essential to success. in particular, some librarians seemed to feel that automation was a temporary affair, definitely of less importance and significance than current manual operations. some did not recognize the sacrifices in regular production that would be necessary and some did not appreciate the continuing nature of development work. background two important prerequisites to progress in library automation were money and technical readiness. the government supplied the first, industry the second. the announcement by ibm in 1964 of its system 360 occurred at a fortunate time for the american library community. president johnson's administration had launched enormous programs in support of education. the library services and construction act was soon to channel millions of dollars into library plant expansion and, perhaps more significantly, the higher education act of 1965 was to sponsor research, which ui1til then had only the support of limited funds from the council on library resources, inc., and the national science foundation. (support from the national science foundation was largely, although not exclusively; directed toward discipline-oriented information services; one of the largest nsf grants went to the university of chicago library.) it was the right time to invest in library automation. important milestones were already behind the library community: the national library 10 journal of lihm1'y automation vol. 7/1 march 1974 of medicine's medlars program was well underway, the airlie conference on library automation had been held and its report published ("the white book"), and the library of congress automation feasibility study ("the red book") had appeared. 1 • 2 the first marc format was being tested in the field. in computer technology, third generation equipment represented major increases in computing power, processing speed, reliability, and capacity to store data in machine-readable form. ibm's sales force was successful beyond imagination in getting system 360's installed in large universities, as well as in business and government. ibm promised a new kind of software-time-sharing-which would virtually eliminate the tremendous mismatch of data processing speed between the human being and the machine. the new methods of spreading computer power through teleprocessing and time-sharing promised to make the computer at least competitive with and possibly an improvement over "antiquated" manual systems of providing rapid access to large and complex data files. within this relatively unknown environment, universities and libraries entered the software development process, which if successful, could enable them to catch up where they had been hopelessly falling behind. circulation, book purchasing, and technical processing loads in many libraries seemed to double and triple overnight as the country's schools and their programs grew to accommodate expanding enrollments. manual systems that had been reasonably workable and responsive in environments characterized by slow growth demonstrated significant and disturbing defects -the inability to deal with peak loads, or rapidly changing loads. the same effects were felt in administrative and academic computing: a bigger and more complex payroll, more students to register, construction contracts to monitor, more research grants which demanded bigger computers, and so on. these were truly boom years. but in the academic community there was still another force developing which was ultimately to be of even greater significance for libraries than the inconveniences of being unable to handle the housekeeping load: a dramatic rise in the expectations of patrons, especially in the academic community, where computers already abounded. libraries had come to be felt by some as strongholds of conservatism and expensive luxuries; librarians were faulted for not "putting the card catalog onto magnetic tape," for not implementing automated circulation systems, or otherwise failing to take advantage of new and powerful data processing techniques. the libraries were caught amidst a variety of sometimes conflicting, sometimes complementary factors: the visionary ignorance of the computer salesman, the senior academic officer possessed by the computer dybbuk, a lack of sympathy or understanding among some computer center managers, a lack of appreciation by students and faculty of the complexity of identifying, procuring, and cataloging unique copies of what must be the least standardized product known to man, and their own lukeinstitutional political and fiscal facto1'sjveaner 11 warm commitment to undertake the hard work required to learn how to use the computer resource. anxieties about jog displacement caused some library staff to look upon computers with trepidation, thus further placing the librarian in a defensive position. while these forces were taking shape, the library's bibliographic activities continued to be seriously hampered by inadequate international bibliographic control.~~ some essential computer hardware, especially the programmable crt terminal with an adequate character set, was either nonexistent or totally unsuitable to library applications. in this institutional context librarians entered the world of computers and data processing. t purpose it is the purpose of this report to examine in some detail how internal institutional factors affected the development of computerized bibliographic systems, and especially to consider nontechnical, negative factors: what slowed down or inhibited the applications of computers in librarianship? this report is not concerned with the merits or demerits of specific systems or their features; indeed, the investigator did not inquire about system specifications. major questions centered about the factors which fostered or hindered the development p1'ocess, regardless of the merit of a project or system. scope investigation was limited almost solely to those institutions considered likely to have large scale, in-house development projects using third generation computer equipment. the majority of places visited were large academic libraries. the time span included in the survey begins approximately in 1967 and ends in 1971. a total of twenty-four institutions was visited and some 100 persons interviewed; a list of the institutions visited is in appendix 1. methodology site visits and i nte1'views arrangements were made to visit four types of individuals: the director of libraries, the head of the library's system development department, the director of the computation center, and whatever principal institutional officer was managerially and/ or financially responsible for campus computing. considerable variation was found in the type of person assigned this last responsibility-it could be the provost, the vice-president u implementation of the library of congress' shared cataloging program under title ii6f the higher education act of 1965 was soon to alter this situation dramatically. t the painful trauma libraries and librarians experienced in getting into computers is too well documented to summarize here. perhaps the best summary has been done by stuart-stubbs. a 12 ] oumal of library automation vol. 7/1 march 197 4 for academic affairs, or the vice-president for business/ financial affairs. choice of the major institutional official to be interviewed was often determined by the pattern of computing in a particular institution, or the facility which supported the development effort. at first the investigator attempted to utilize a structured questionnaire for interviewing. this very quickly broke down, as the interviewees were generally voluble and ranged widely over many related topics or items which they would have been asked about later. accordingly, after the first few interviews, the formal questionnaire approach was dropped and a simple checklist of major questions kept on a few cards to make sure that each major issue had been addressed. every interviewee received the investigator graciously and none was unwilling to talk; indeed, if anything the opposite was the case-most persons seemed to be eagerly waiting for an opportunity to air their views. visits and interviews occurred during the period january-april1972. literature searches searching the literature on this topic has been extremely frustrating. in the literature of computer science and management, there are many articles on pricing algorithms, machine resource allocation schemes, and issues of managing the computer facility, but none specific to the topic of this report. besides scanning professional literature, the author has regularly conducted for the past year monthly computer searches via the ucla center for information service's sdi service. abstracts and citations were searched in research in education (rie) and current index to journals in education (cije). with respect to problems faced by the library in acquiring computer services, the results have been nil in both cases. the author reluctantly concludes that no major recent studies have yet been published in this sensitive area, although two papers by canadian librarians are very helpful. 3• 4 the national academy of sciences/computer science and engineering board's information systems panel appears to have come closest to identifying the issues in its report, library and information technology: a national systems challenge. still, the comments in that report are highly generalized and do not grapple with specifics. 5 structure of educational computing most of the visited institutions maintained separate facilities for administrative and academic computing, while a few ran combined facilities or were in the throes of consolidating their facilities. the differences between administrative and academic computing have historical roots deeply embedded in institutional soil. administrative computing is usually an outgrowth of punched card installations first set up for payroll and financial reporting. academic computing, on the other hand, has its origins within the institution's instructional and research programs. typically it has been supported by external grants and contracts and has been oriented toward institutional political and fiscal facto1'sjveaner 13 the "hard" sciences. until the recent dropoff in federal support of higher education, academic computing was a money maker (through the overhead on grants and contracts) while administrative computing was a money spender. administrative computing typically very little computational work is done in administrative applications; most of the computer work is associated with input, update, reading records, writing records, and printing reports. except for the pay.roll application, the consumer group has tended to be somewhat smaller and less transient than the academic group. but to university administrators the computer could do much more than write checks and pay bills. many significant administrative applications had already been installed on second generation equipment: faculty-staff directories, inventories of space, supplies, and equipment, records of grades, course consumption reports, etc. all these tended to expand the user group, increasing competition for the resource. the advent of third generation equipment made it attractive for administrators to think about applications centered around the so-called "integrated data base." this led to a demand for further new services for the registrar, fund raising and gift solicitation, student services, purchasing, etc. conventional administrative computing-particularly that part of it which generated regular reports-lent itself naturally to batch processing, and indeed many of the early computer installations actually continued established punched card operations, merely using the computer as a faster calculator and printer. the administrative computing shop is typically characterized by (or hopes to be characterized by) great systems stability and dependability, a cautious and measured rate of innovation, and in the opinion of some academic computing types, not much imagination. file integrity, backup and recovery, and timely delivery of its products are prime goals in an administrative computing system. the administrative computing facility very much resembles the library in two important aspects: ( 1) it is a production system; and ( 2) it is almost entirely an overhead function, i.e., there is little or no attempt at cost recovery from system users for its services. academic computing academic computing is a much different world. it serves a large, vociferous, .influential, and mostly technological user community, many of whom ~~e not only competent in programming, but more importantly, possess ready cash. but this is changing: as academic computing expands to service users in the humanities and social sciences rather than mainly those in the "hard" sciences, the user group is growing and it will probably not be long before it embraces the total academic community. in hard science applications, the academic facility typically performs an 14 journal of library automation vol. 7/1 march 1974 enormous amount of computing ("number crunching") with a relatively small amount of output. system backup and recovery is important to the academic computing facility, but file integrity responsibility may often be assigned to the user since such a center sometimes does not maintain the data base but merely provides a service for manipulating it. the main components of academic use are departmentor discipline-oriented research and student instruction, the latter being particularly strong if there is a well-established computer science department. software development has customarily played a major role in academic computing and the usual practice was to actively seek out imaginative systems programmers for whom change and system improvement are food and drink. consequently, instability, both in hardware and software, has been more the rule than the exception in the recent past, although as the management of computer facilities matures, this too is changing. currenttrendsandstatus it is obvious from the above that administrative and academic computing have been characterized by diametrically opposed machine and managerial requirements. where they have been combined in the same facility, tensions have prevailed and neither user was happy. in a few instances known to the writer, such combinations have been abortive and a reversion made to divided facilities. but as computing matures it is becoming evident that operational stability is needed for all types of computing, not just administrative computing. additionally, the financial crises now prevalent in institutions of higher education have brought more realistic attitudes to the fore in understanding just what kinds of facilities can be afforded, and how they should be managed. additionally, the economies of scale, the increasing flexibility of hardware and growing sophistication of software are now combining to form an environment which can better satisfy all potential users of computers. there are clear indications that a unified, well-managed shop with competent staff might now economically and efficiently serve a variety of applications, including administrative and academic-on the same facility. however, this is a developing trend and does not correspond with what the writer actually observed during his visits. in situ he saw much evidence that anthony oettinger's observations of some years ago were still valid: ... routine scheduled administrative work and unpredictable experimental work coexist only very uneasily at best, and quite often to the serious detriment of both. where the demands of administrative data processing and education require the same facilities at precisely the same time, the argument is invariably won by whoever pays the bills. finances permitting, the loser sets up an independent installation. 6 indeed, it would not be unreasonable to conclude from the interviews that in most places visited, computing during the period 1967-71 was in a institutional political and fiscal factorsjveaner 15 state of disarray. there is abundant and disagreeable evidence of technical incompetence, lack of management ability, ill spent money, communication failures, and naive and disillusioned users. but it would be a mistake to conclude that the failures in library automation are attributable primarily to computer-oriented personnel or hardware problems-librarians in their own way displayed many of these same failures. it would be another mistake to dwell excessively on the high failure rates observed. in any complex technological endeavor, the rate of failure is dramatically high at the beginning; there is ample evidence here from the aircraft and space industries. indeed, the likelihood of a first success in anything complex-library automation is complex, as we have learned the hard way-is practically nil. organization and management problems: the academic computing environment early academic computing facilities were typically run by faculty members in engineering, applied mathematics, computer science, or related fields. this arrangement was satisfactory when computers were small, relatively primitive, and the user community was confined to those few people who could program in machine language or assembly language. as equipment became bigger and more powerful, and as higher level programming languages developed, more and more people learned programming. correspondingly, the task of managing the computer facility grew rapidly in size and scope. the budget of a large computer center in a modern university can easily run to several millions of dollars annually. the manager must balance seemingly innumerable, complex forces: personnel, management, government and vendor relationships, demands from vocal users, establishing priorities, the challenge of hardware advances, marketing, pricing services, balancing the budget, etc. it soon became clear that few faculty members possessed either the multifaceted talents or the experience required for effective management. as the center's budget grew, and particularly as the shift was made from second to third generation equipment, th,e faculty member tended to be replaced by the technician as manager. unf01tunately for many of the facility users, the technician tended to promote his own technical interests in software development or hardware utilization. in some instances, the user community felt that the facility was being run more for the benefit of the staff than for the users. the technician-manager often looked at the computer as his personal machine, much as some faculty members had earlier felt the computer to be their own private preserve. the vice-president of one university expressed the view that the technician-manager doesn't really have an institutional loyalty tied to the goals and objectives of the academic programs; he is more loyal to the machine or the software. in a school with a long history of computer utilization, there had been no tech16 journal of library automation vol. 7/1 march 1974 nician in charge of the computer facility for a decade. yet in a school not too far away, an officer indicated that his institution had "made the same mistake twice in a row" by hiring a technician to manage the computer facility. the technician-manager represents a highly personalized management style, one in which goodwill, friendship, or personal interest is the key to effective service. it can hardly represent an arrangement for the successful development and implementation of computerized bibliographic systems. in the third and current organization and management phase of academic computer facilities, the professional manager is in charge. schools are now beginning to see the need to develop formal charters for their computing centers, quasi-legal instruments which will lay out their specific responsibilities as service agencies. a professionally managed service agency eliminates one of the most irritating elements in the allocation of computer resources: personal judgment by the faculty or technician-manager as to the worth of a project, which was so prevalent during earlier management stages. at the time of the interviews, very few institutions actually had such charters, but their need was being recognized. it is now universally accepted that the computer center can no longer be the plaything of the faculty nor the expensive toy of the technician. organization and management: the administrative environment because of its historical development the administrative computing facility was usually first run by someone with an accounting or financial background. (academic computing persons occasionally put disparaging labels on such people as "edp-types" or characterized them as having a "punched card mentality.") the nature of the workload virtually meant that the administrative shop would be set up mainly for batch processing and any data base services provided for other users would involve printed lists. such facilities were found satisfactory by a number of libraries even for applications such as circulation, which produced gigantic lists-probably because it represented a vast improvement over an antiquated, poorly designed, or overloaded manual system. however, there was at least one major technical consideration which had direct political and financial implications for the library which turned to the administrative computing facility for its computer support. this was the library's need to support and manipulate a data base with nearly every data element of variable length-a requirement that was practically nonexistent in administrative computing. some facilities were unable or unwilling to meet this requirement. the move from tape-oriented systems to mixed disc and tape systems on third generation equipment necessitated an upgrading of programming staff, and brought into the administrative shop the same clearcut distinction between system programmers and application programmers which had institutional political and fiscal factorsjveaner 17 emerged earlier in the academic shop. this change in turn demanded appointment of more knowledgeable facility managers, many of whom were drawn from business and industry rather than the ranks of in-house accounting staff. this transitional period was characterized by two enormously challenging parallel efforts: the conversion of existing programs to run on third generation equipment and the development of new applications. to an extent these responsibilities were competitive, and from this viewpoint it was certainly not a propitious time to embark upon anything as complex as bibliographic data processing. yet numerous workable systems emerged for circulation, book catalogs, ordering and accounting systems, and serials lists. these were not accomplished without anguish as the library did not control the machine resources and often did not control the human resources -the facility manager tended to make his pliority decisions to please his boss who was certainly not the librarian. besides, no application could really take precedence over payroll or accounting in the administrative shop. to the librarian it was more like borrowing another person's car than renting or owning a car: when the resource was urgently needed someone else had first call. organization and management: the library automation endeavor a detailed study of this subject is not within the scope of this investigation. however, it will be useful to note that the organization and management of library automation activities demonstrate development phases which closely parallel those in the computing environment: 1. a stage in which the user himself ( cf. accountant or faculty member) undertakes to perform the activity. in this stage individual librarians learned programming, did their own design work, wrote, debugged, and ran programs themselves. (this was possible in the "open shop" environment prevalent in many early computer facilities.) 2. a stage in which the technician-in this case a librarian with appropriate public service expertise (for circulation applications) or technical processing knowledge (for acquisitions, cataloging, or serials) -took charge of an organized development effort, hired his own programmers and systems analysts, and negotiated directly with the computer facility.* 3. a stage in which the professional system development manager is hired to oversee the total effort. such a person is sometimes drawn from business or industry, is a seasoned project manager, and has broad knowledge of computers, especially in the area of costs. such an ap*the technical person need not be a librarian. northwestern university represents a significant instance where a faculty member in computer sciences and electrical engineering undertook the development effort. 18 ]oumal of library automation vol. 7/1 march 1974 pointment is more common in the large library, the consortium, or network. human problems associated with rapid change in institutions some institutions, particularly in their administrative functions, became embroiled in a seemingly endless round of internal psycho-social problems which did not make the environment conducive to problem solving. the move to computerizing manually oriented functions, whether in the library or other parts of an institution, was found to be extremely threatening to established departmental structures. it was consistently reported that the political and emotional aspects of system conversion, both in the libra.ry and elsewhere, were much more aggravating than the technical aspects. the problem simply showed up first outside the library because applications of computers occurred there earlier. departments were sometimes unwilling to give up data for computer manipulation for fear that computerization would take jobs away. this phenomenon is not unknown in librarianship where some professionals take an extremely proprietary attitude toward bibliographic data. now pressures from governments, legislatures, and the academic community at large are gradually establishing the concept that some categories of data are corporate, and do not belong to a specific individual or department, or even to an institution, but should be shared through networking or other mechanisms. but the rapidity of microsocial change and its upsetting emotional consequences caught some library leaders unawares. a considerable reeducational process for both management and labor is required to smooth the transition to the new view. motivation problems it is difficult to elicit sound comment concerning motivation (or lack thereof) as a deterrent to progress in library automation. it is an emotional subject and neither the librarians nor the programmers come out "clean." the prima donna computer programmer, much in evidence in the early days of computer center development, is very much on the wane these days. like the spoiled child, the prima donna programmer could only exist where personal interests were permitted to take precedence over social goals-or perhaps where institutional goals for the computer facility had not been clearly articulated or had not yet come into focus. some prima donnas, partly out of ignorance, partly through a stereotyped image of library activities, were inclined to disdainfully dismiss library applications as "trivial," and demand "really challenging" assignments. but the librarians had their prima donnas, too. some had learned enough programming to be a little dangerous and they then felt like peers who could tell the computer center not only what to do but how to do it. at first, few members of the library staff were willing to learn how to arinstitutional political and fiscal factorsjveaner 19 ticulate their specifications and requirements to the management of a computer facility. most librarians expected some kind of miraculous magic, akin to a wave of the hand, to bring a computer system to reality. very few understood the heuristic nature of development. so there were barriers of status, depth of knowledge, and language-any one of which would have sufficed to kill the development of the good motivation essential to breaking new gro~nd. in the wrong combination they could present an overwhelming conspiracy, for their mutual interaction could only produce polarization and intransigence. the library and the computer facility the role of similarities and differences for a long time the library has been the "heart of the university." until the advent of the computer, little could challenge the supremacy of the library as the principal resource of an educational institution. even the faculty could be put into second place, since it was difficult to attract high quality faculty without good library resources, and the faculty were to a greater degree transient, for the library was considered "permanent," an investment for all time. the computer represents a new and challenging force in the arena where shrinking resources are allocated among competing academic users. both the library and the computer facility have experienced exceedingly rapid growth in the recent past, concurrent with an expanded demand for services which can easily outstrip available resources. among some of the larger academic libraries, the staff of the computer center may be half or greater than half that of the library. important differences between the two services have recently come into focus. first, most of the services and benefits of the library are intangible. because of this it has always been difficult to measure the cost benefit of the library as an institution, and it is well known that counts of the number of people entering the door or the number of circulations are far from true measures of the library's functional success. the computer, on the other hand, is a relentless accounting engine; computer facilities can produce endless statistics on the number of jobs run, lines printed, terminal hours provided to users, turnaround time, cards punched, etc. the computer's output is extremely tangible and can be more directly and easily related to academic achievement than can library use. a second major difference lies in apparently different financial roles within the institution. in most organizations, the library is run as an overhead expense, without any attempt to charge back to users or departments proportional costs of utilization. like air, the library resource is there for anyone to use as much or as little as he pleases; the library gets a "free ride," but the computer center is expected to pay its own way. this dichotomy is often explicitly designated as the "library-bookstore" duo model. furthermore, since the library does not generate much in the way of re20 journal of library automation vot 7/1 march 1974 search grants and contracts, it is looked upon as a consumer rather than a producer of financial resources. in fact, those who support computing in preference to books point to. the fact that overhead income generated by computer-related research grants and contracts is shared with the library which may have done little to contribute toward the acquisition of such income! in some institutions the situation has become critical indeed because of the recent substantial reductions in federal· support. much political in-fighting has been necessary to maintain current levels of computer activity, and not all such efforts· have been successful.· some institutions have been forced to cut back on computing power, merge facilities, or combine resources with other institutions. · · · · several years ago when the national science foundation imposed an expenditure ceiling on grants, associated overhead income was correspondingly reduced. one computer center director was reported to have suggested that the effect of this overhead cut could be nullified by a simple, internal reallocation of funds, say by taking the needed amount from the budget of another agency on campus of less significance to researchers and scientists, such as the library. this attitude is clear evidence that the library has lost its sacred cow status as a "good thing" on the campus. it too must justify itself. close examination of the library and the computer facility gives clear evidence that both deal with the same commodity: information. within the recent past several computer facilities have changed their designations to "information processing" facilities or centers. several institutions, notably the university of pittsburgh and columbia university, have coalesced the library and the computer center organizationally or have both units reporting to a vice-president for information services. the recognition and furtherance of this natural linkage may do much to reduce the potentially destructive competition which can characterize the relationship between the two units. there are remarkable growth parallels between the two facilities-the library acquiring and processing more and niore books in response to expanded publication patterns, more users, and the· growth of new ·disciplines and interdisciplinary research, while the computation facility moves rapidly from one generation of software and hardware to the next. the expansion of both organizations produces seemingly equal capital-intensive and labor-intensive pressures: library processing staff doubles and triples, while the ·newly acquired books demand ·more in the way of housing, whether of the traditional library type or warehouse space; the computer center moves toward more sophisticated hardware, especially terminals and communications, which need to be supported by greater numbers of still more highly qualified· systems programmers, communication experts, and user services staff. both services have a marketing. problem; but the computation facility, being relatively more dynamic and more interactive (because of terminal services), can be more sensitive and responsive, .financially and technically, to its clientele than can the library. only now institutional political and fiscal factors/veaner 21 with the emphasis upon computerized bibliographic networking has the library as an institution begun to approach the marketing strategies and the effective user feedback already well developed in computation facilities. service capacity, resource utilization and sharing differences both in service capacity and resource utilization represent a key political issue affecting the future of both libraries and computer facilities. in major universities, the budget for the computer facility is now not far from the library budget in size, and in a few institutions it exceeds the library budget. with the diminution of external grants and contracts, the two organizations compete for the same hard dollars. this economic competition can either drive the two facilities apart, dividing the campus, or cause them to coalesce-as has been the case at columbia and pittsburgh. despite its high operating costs, from the viewpoint of resource utilization, the well-managed computer facility can almost always point to an excellent record.§ no matter how well managed, the research library can never make this claim in the context of its current materials and processing expenditures, much of which by definition is aimed at filling future needs. the library and its patrons cannot "use" all the resources at their command; the library could not even service all the patrons should they demand the use of "all" the resources. in contrast, the computer facility (particularly large on-line systems with interactive capabilities) can be very efficiently utilized even when demand is heavy. thus, to the "objective" eye, it would appear that in the computer facility both the institution and the individual patron get more value for their dollar than they do in the library, which in comparison resembles a bottomless financial pit. one may counter that apples and oranges are being compared, but the institution which pays their bills nevertheless makes the comparison. flexibility, inflexibility, and the future besides better resource utilization, the computer facility offers the patron far greater flexibility of resource use than can the library. there is no way a large collection of books on the celtic language or the military history of the austro-hungarian empire can help a professor of structural engineering, a student of marine biology, or a researcher in modern urban problems. even the books these people actually need and use cannot easily assist others, as relevant data in them is not indexed or readily available for computer manipulation. · the point is that, unlike the library, the computer is a highly elastic universal tool, one that each user can temporarily shape to his own need, replicate .the shape later, or if he wishes change the shape at will. the traditional.lib:rary has no such flexibility; its main bibliographic retrieval de§in fact, if a computer resource is not much used and isn't "carrying its weight," it can be disposed of, by sale if purchased, or by cancellation if leased. 22 journal of library automation vol. 7/1 march 1974 vice-the card catalog-is especially noted for its high maintenance cost, its limited ability to respond to complex queries, and a general fixity of organization and structure that is ever at variance with changing patron expectations and interests. (if computers can be flexible, why can't the library?) there is much in the library that is not used because it is inaccessiblelocked up in an inflexible retrieval tool or unavailable because the stateof-the-art (both in bibliography and computer science) or staffing does not yet permit far deeper access via "librarian-negotiators" and patrons at terminals interacting with large and deeply indexed data bases. as long as major portions of the library budget and staff are devoted to housekeeping and internal technical processing, the library will look less good, less "costbeneficial" to the academic community than does the computer facility. but there is growing recognition that both institutions deal with information processing which covers a wide spectrum of time. true, the storage formats differ, but this may be a temporary phenomenon. as progress is made on improved, less expensive conversion of data from analog to digital form and vice-versa, the day may arrive when the library and the computer facility are indistinguishable. will the library become an information utility? computer utilities are an important developing trend and it is sometimes suggested that library services could be delivered within the utility model. utilities and libraries as they exist today have very different characteristics. a utility can be defined as a system providing a relatively undifferentiated but tangible service to a mass consumer group and with use charges in accordance with a pricing structure designed for load leveling (i.e., optimization of resource utilization). typically, a utility both wholesales and retails its services. within this definition, a conventional library cannot be construed as a utility; its services are generally intangible and very highly differentiated-indeed, chiefly unique, for rarely is one book "just as good as another"; its clientele is not the general public but a highly select group which itself contains highly unequal concentrations of users; and almost no libraries impose user charges in the interest of cost recovery; practically speaking, there is only one united states wholesaler (of bibliographic data) -the library of congress. this situation is changing in several respects. first, the establishment of practical, computerized bibliographic networks has introduced among participating institutions cost sharing schemes closely resembling the load leveling or rate averaging algorithms prevalent among utilities.ll these han example of rate averaging is the practice of the ohio college library center to lump total telecommunication cost and prorate it into the membership fee, in effect creab":ng a distance independent tariff. (this arrangement does not hold outside of ohio.) institutional political and fiscal factorsjveaner 23 new ideas have been readily accepted by libraries and could even become the basis for balancing more equitably the costs of interlibrary loan traffic. second, specialized "information centers" have evolved in certain fields, partially as a consequence of lack of responsiveness (or slow turnaround) by conventional library services, and "for profit" commercial services have been set up. examples of the latter include the european s'il vous plait and its american counterpart, f.i.n.d. (often such commercial services do not hire librarians as they are considered too tradition bound.) a third force which is rather inchoate at the moment may soon take on a recognizable shape: facilities management. under such a scheme, the complete management responsibility for all or part of a function is contracted to an outside vendor. for instance, it is conceivable that some libraries in the near future may have no in-house staff for technical processing. services would be purchased totally from a vendor or obtained from his resident staff, much as computer centers buy specialized expertise through the "resident s.e." (systems engineer). the gradual buildup of computerized bibliographic services offers an excellent opportunity for commercial ventures into turnkey bibliographic operations for libraries. this would bring the libraries one step closer to the utility concept, as they buy a complete package from a wholesaler who probably services many customers. the traditional library service concepts we know today may undergo drastic changes in financing and in methods of delivery. beyond the commercialized or contractual arrangement for technical processing, which is only one component of the total information flow, lie unknown territory and little explored concepts: use charges for library services (the bookstore model), the "for profit" library, the complete information delivery system integrated with computers, communication satellites, and cable tv. if the computer-based library is to become an information utility, a major accommodation will be needed in the financing arrangements, perhaps in form of user charges-for no utility can survive without regulated demand. an unlimited, uncontrolled demand for any product or service is untenable, for without regulation (i.e., pricing) demand rapidly outruns supply. in the traditional library, where theoretically every user has the "righf' to unlimited demand, this never happens for several reasons: (1) not all potential patrons elect to use the resource; ( 2) the users must usually go to the library to access the bibliographic apparatus and obtain the materials held by the library; ( 3) every item in a library collection does not have an equal probability of use; and ( 4) there is a finite rate at which human beings can "use the resource," i.e., people can read just so f~st. none of these self-limiting factors applies to say, electric power, radxo and tv broadcasting, telecommunication services, or similar utilities. the library picture could become quite different if these limitations were removed or mitigated. suppose the patron could access the bibliographic apparatus through his home computer terminal attached to his tv 24 journal of libmry automation vol. 7 ;1· march 1974 in the "wired city." further suppose that he could receive selected, short items (where time of delivery is important to him) directly at his tv set, or longer items having less time value as microforms or hard copy delivered by mail or private delivery systems. given such possibilities, the collecting policies of individual .. libraries" (if they continue to be called by that name) might well change drastically so that nationally, collections might become much more standardized or .. homogenized" -increasing the likelihood that individual holdings will have more nearly equal use probabilities. this would imply the need for one or more national and/ or regional centers for servicing the less used materials, along with appropriate delivery systems and pricing schedules. conclusion work on library automation has proceeded during a highly developmental period in the history of computing. in this sense, librarianship has suffered no worse than any other computer application, nearly all of which have gone through traumas of design, installation, redesign, reprogramming, etc. the main distinction is that in many of these other applications -government, military, industrial, or commercial-there have been . far greater resources available to the task and vastly greater experience with the development process. despite the obstacles, progress in computerized bibliographic work has been far more significant and has achieved far more than many librarians-especially those unaccustomed to the developmerit cycle..;..can appreciate. the snowballing growth of practical consortia and networks along with the successful installation and operation of several on-line bibliographic systems has already changed the face of libtarianship in ·a very short time. like the breaking of the sonic barrier, once the initial.difficulty is overcome, further progress is easier. the ·computer has successfully achieved what librarians have until recently· only paid lip service to: cooperation and wide sharing of an expensive· and large· resource. though the linear growth model in libraries has been dead for some time, the recognition of this fact has riot yet penetrated the entire profession. if libraries are to survive as viable institutions throughout this century and into the next, their leaders inust solve the financial, space, ·and human communication problems inherent in growth. local autonomy, local self-sufficiency, and the "freedom" to ·avoid, evade, and even· undermine national standards now show up as expensive and dangerous luxuries-potentially self-destructive. only through the computet will true library cooperation be possible~ only the development of regional and national bibliographic networks,· with the assistance of substantial federal funding, can really .. save" the library. the computer is actually the' library's life insurance and blood plasma .. a failure to respond to the challenge of the ·computer could be fatal, for it is increasingly apparent that patrons growing up in the computer era will not patiently interact'with··library systems geared to nineteenth-century methods. nothing institutional political and fiscal factorsjveaner 25 in the educational system exists to .force people to use a given resource;

december 2012 44 abstract this study examines the attributes that have been used to assess file formats in literature and compiles the most frequently used attributes of file formats to establish open-standard file-formatselection criteria. a comprehensive review was undertaken to identify the current knowledge regarding file-format-selection criteria. the findings indicate that the most common criteria can be categorized into five major groups: functionality, metadata, openness, interoperability, and independence. these attributes appear to be closely related. additional attributes include presentation, authenticity, adoption, protection, preservation, reference, and others. introduction file format is one of the core issues in the fields of digital content management and digital preservation. as many different types of file formats are available for texts, images, graphs, audio recordings, videos, databases, and web applications, the selection of appropriate file formats poses an ongoing challenge to libraries, archives, and other cultural heritage institutions. some file formats appear to be more widely accepted: tagged image file format (tiff), portable document format (pdf), pdf/a, office open xml (ooxml), and open document format (odf), to name a few. many institutions, including the library of congress (lc), possess guidelines on file format applications for long-term preservation strategies that specify requisite characteristics of acceptable file formats (e.g., they are independent of specific operating systems, are independent of hardware and software functions, conform to international standards, etc.).1 the format descriptions database of the global digital format registry is an effort to maintain a detailed representation of information and sustainability factors for as many file formats as possible (the pronom technical registry is another such database).2 despite these developments, file format selection remains a complex task and prompts many questions that range from a general interest (“which selection criteria are appropriate?”) to more specific (“are these international standard file formats sufficient for us to ensure long term preservation and access?” or “how should we define and implement standard file formats in harmony with our local context?”). in this study, we investigate the definitions and features of standard file formats and examine the eun g. park (eun.park@mcgill.ca) is associate professor, school of information studies, mcgill university, montreal, canada. sam oh (samoh@skku.edu) is corresponding author and professor, department of library and information science, sungkyunkwan university, seoul, korea. mailto:eun.park@mcgill.ca mailto:samoh@skku.edu information technology and libraries | december 2012 45 major attributes of assessing file formats. we discuss relevant issues from the viewpoint of openstandard file formats for long-term preservation and open access. background on standard file formats the term file format is generally defined as what “specifies the organization of information at some level of abstraction, contained in one or more byte streams that can be exchanged between systems.”3 according to interpares 2, file format is “the organization of data within files, usually designed to facilitate the storage, retrieval, processing, presentation, and/or transmission of the data by software.”4 the premis data dictionary for preservation metadata observes that, technically, file format is “a specific, pre-established structure for the organization of a digital file or bitstream.”5 in general, file format can be divided into two types: an access format and a preservation format. an access format is “suitable for viewing a document or doing something with it so that users access the on-the-fly converted access formats.”6 in comparison, a preservation format is “suitable for storing a document in an electronic archive for a long period”7; it provides “the ability to capture the material into the archive and render and disseminate the information now and in the future.”8 while the ability to ensure long-term preservation focuses on the sustainability of preservation formats, the document in its access format tends to emphasize that it should be accessible and available by users, presumably all of the time. many researchers have discussed file formats and long-term preservation in relation to various types of resources. for example, folk and barkstrom describe and adopt several attributes of file formats that may affect the long-term preservation of scientific and engineering data (e.g., the ease of archival storage, ease of archival access, usability, data scholarship enablement, support for data integrity, and maintainability and durability of file formats).9 barnes suggests converting word processing documents in digital repositories, which are unsuitable for long-term storage, into a preservation format.10 the evaluation by rauch, krottmaier, and tochtermann illustrates the practical use of file formats for 3d objects in terms of long-term reliability.11 others have developed and/or applied numerous criteria in different settings. for instance, sullivan uses a list of desirable properties of a long-term preservation format to explain the purpose of pdf)/a from an archival and records management prospective.12 sullivan cites device independence, self-containment, self-describing, transparency, accessibility, disclosure, and adoption as such properties. rauch, krottmaier, and tochtermann’s study applies criteria that consist of technical characteristics (e.g., open specification, compatibility, and standardization) and market characteristics (e.g., guarantee duration, support duration, market penetration, and the number of independent producers). rog and van wijk propose a quantifiable assessment method to calculate composite scores of file formats.13 they identify seven main categories of criteria: openness, adoption, complexity, technical protection mechanism, self-documentation, robustness, and dependencies. sahu focuses on the criteria developed by the uk’s national archives, which include open standards, ubiquity, stability, metadata support, feature set, examining attributes of open standard file formats for long-term preservation and open access | park and oh 46 interoperability, and viability.14 a more comprehensive evaluation by the lc reveals three components—technical factors, quality, and functionality—while placing a particular emphasis on the balance between the first two.15 hodge and anderson use seven criteria for sustainability, which are similar to the technical factors of the lc study: disclosure, adoption, transparency, selfdocumentation, external dependencies, impact of patents, and technical protection mechanisms.16 some institutions adopt another term, standard file formats, to differentiate accepted and recommended file formats from others. according to the david project, “standard file formats owe their status to (official) initiatives for standardizing or to their widespread use.”17 standard may be too general to specify the elements of file formats. however, there is a recognition that only those file formats accepted and recommended by national or international standard organizations (such as the international standardization organization [iso], international industry imaging association [i3a], www consortium, etc.) are genuine standard file formats. for example, iso has announced several standard file formats for images: tiff/it (iso 12639:2004), png (iso/iec 15948:2004), and jpeg 2000 (iso/iec 15444:2003, 2004, 2005, 2007, 2008). for document file formats, pdf/a-1 (iso standard 19005-1. document file format for long-term preservation) is one example. this format is proprietary to maintain archival and recordsmanagement requirements and to preserve the visual appearance and migration needs of electronic documents. office open xml file format (iso/iec 29500–1:2008. information technology—document description and processing languages) is another open standard that can be implemented from microsoft office applications on multiple platforms. odf (iso/iec 26300:2006. information technology—open document format for office applications [opendocument] v1.0) is an xml-based open file format. regardless of iso-announced standards, some errors in these file formats have been reported. for example, although pdf/a-1 is for longterm preservation of and access to documents, studies reveal that the feature-rich nature of pdf can create difficulties in preserving pdf information over time.18 to overcome the barriers of pdf and pdf/a-1, xml technology seems prevalent for digital resources in archiving systems and digital preservation.19 the digital repository community is treating xml technology as a panacea and converting most of their digital resources to xml. the netherlands institute for scientific information service (nisis) adopts another noteworthy definition of standard file formats. it observes that standard image file formats “are widely accepted, have freely available specifications, are highly interoperable, incorporate no data compression and are capable of supporting preservation metadata.”20 this definition implies specific and advanced ramifications for cost-free interoperability and metadata, which closely relates to open access. open standard is another relevant term to consider in file formats. although perspectives vary greatly between researchers, open standards can be acquired and used without any barrier or cost.21 in other words, open standard products are free from restrictions, such as patents, and are independent of proprietary hardware or software. since the 1990s, open standard has been broadly adopted in many fields and is now an almost compulsory feature in information services. information technology and libraries | december 2012 47 to follow the national archives’ definition, open standard formats are “formats for which the technical specifications have been made available in the public domain.”22 in comparison, the folk and barkstrom approach opens standards from institutional support perspectives, relying on user communities for standards that are widely available and used.23 on a more specific level, stanescu emphasizes independence as the basic selection criteria for file formats.24 others, such as todd, propose determining whether a standard should be more open than others by applying criteria: adoption, platform independence, disclosure, transparency, and metadata support.25 other factors considered by todd include reusability and interoperability; robustness, complexity, and viability; stability; and intellectual property (ip) and rights management.26 echoing the lc, hodge and anderson also suggest a list of selection criteria that have been grouped under the banner of “technical factors”: disclosure, adoption, transparency, self-documentation, external dependencies, impact of patents, and technical protection mechanisms.27 researchers agree that open standard file formats are less obsolete and more reliable than proprietary formats.28 close examination of the nisis definition mentioned above reveals that standard file formats are in reality not free, nor do they allow unrestricted access to resources. the three file formats that iso has announced (pdf/a, ooxml, and odf) are proprietary and sometimes costly. they also prohibit the purchase of access to a proprietary standard, although there is an assumption that a standard should be free from legal and financial restrictions. the iso-announced file formats, in short, are only standard file formats, not open standard file formats. for cultural heritage institutions, questions regarding appropriate selection criteria and the sufficiency of existing international standard file formats for long-term preservation and access remain unanswered. there exists neither a uniform method to compare the specifications of different file formats nor an objective approach to assess format specifications that would ensure long-term preservation and persistent access. objectives of the study in this study, we attempt to better define and establish open-standard file-format-selection criteria. to that end, we assess and compile the most frequently used attributes of file formats to establish open-standard file-format-selection criteria. method we performed a comprehensive review of published articles, institutional reports, and other literature to identify the current knowledge regarding file-format-selection criteria. we included literature that deals with the three standard file formats (pdf, pdf/a, and xml) but excluded the recently announced odf format due to the scarcity of literature on odf. among more than the thirty articles initially reviewed, only twenty-five that use their own clear attributes were included in this study. all of the attributes that we have employed are listed by frequency and grouped according to similarities in meaning (see appendix). the original definitions or descriptions that we used are listed in the second column. the file formats that we assessed by their attributes are examining attributes of open standard file formats for long-term preservation and open access | park and oh 48 listed in the third column. when we give attributes without specific definitions or descriptions, “no definite term” is inserted. findings as illustrated in the appendix, the criteria identified by the studies vary. although the requirements and context of the studies may differ, the most common criteria can be divided into five categories: functionality, metadata, openness, interoperability, and independence. first, functionality refers to the ability of a format to do exactly what it is supposed to be doing.29 it is important to distinguish between two broad uses: preservation of document structure and formatting and preservation of useable content. to preserve document formatting, a “published view” of a given piece of content is critical for distribution. other content, such as database information or device-specific documents, needs to be preserved as well. functionality criteria include various attributes related to formats and structure or physical and technical specifications of files (e.g., robustness, feature set, viability, color maintenance, clarity, compactness, modularity, compression algorithms, etc.). second, metadata indicates that a format allows rich descriptive and technical metadata to be embedded in files. metadata can be expressed as metadata support, self-documentation (selfdocumenting), documentation, content-level (as opposed to presentation-level) description, selfdescribing, self-describing files, formal description of format, etc. third, openness refers to specifications of a file format that are publicly available and accessible and formats that are not proprietary. whether seen as a single definition or as a set of criteria, the characteristic that appears to be at the core of the open standard movement is its independence from outside proprietary or commercial control. openness also may refer to the autonomy of a file format, which relies on several factors. first, the document should be self-contained in terms of the content information (e.g., the text), the structural information (i.e., for those documents that are structured), the formatting information (e.g., fonts, colours, styles, etc.), and the metadata information. self-containment does not necessarily mean that an archivist will only have one document to deal with. it does mean, however, that they will have documents that will provide them with all the information to access and process the content, structure, formatting, and metadata. openness is expressed as open availability by some researchers.30 other researchers adopt the term disclosure for expressing that specification is publicly available.31 fourth, is the independence of a document from proprietary or commercial hardware and software configurations, especially to prevent any issues resulting from different versions of software, hardware, and operating systems. this aspect is expressed in the appendix as open standards, open source software or equivalent, standard/proprietary, etc. this also closely relates to independence, one of the five categories in the appendix, expressed as device independencies, independent implementations, no external dependency, no external dependencies, portability, and monitoring obsolescence. having documents in a proprietary format controlled by a third party information technology and libraries | december 2012 49 implies that, at one time or another, this format may no longer be supported, or that a change in the user agreement may lead to restricted access, access to outdated material, or patent and copyright issues. this fact means that the document must be freely accessible, without password restrictions or protection, and without any digital rights management scheme. blocking access to a document with a password can lead to serious problems if the password gets lost. in addition, the size and compactness of the document will influence the selection of a file format. fifth, interoperability primarily refers to the ability of a file format to be compatible with other formats and to exchange documents without loss of information.32 specifically, it refers to the ability of a given software to open a document without requiring any special application, plug-in, codec, or proprietary add-on. adherence to open source standards is usually a good indication of the interoperability of a format. in general, an open standard is released after years of bargaining and agreements between major players. supervision by an international standard (such as iso or the w3c) commonly helps propagate the format. in addition to the five categories mentioned above, other attributes are often used. presentation, authenticity, adoption, protection, preservation and reference are such examples. among these attributes, authenticity, although this is the seventh in the appendix, is one of the most important attributes in archives and records management. it refers to the ability to guarantee that a file is what it originally was without any corruption or alteration.33 specific to authenticity is data integrity, which assesses the integrity of the file through an internal mechanism (e.g., png files include byte sequences to validate against errors). another method of validating the authenticity of a document is to look at its traceability,34 that is, the traces left by the original author and those who modified or opened a file. one example is the difference between the creation date, modification date, and access date of any file on a personal computer. these three dates correspond to a moment when someone (often a different person each time) opened the file. other mechanisms may require log information, which is external to the file. another good indication of authenticity is the stability of a format.35 a format that is widely used is more likely to be stable. a stable format is also more likely to cause less data loss and corruption; hence it is a better indicator of authenticity. presentation includes attributes related to presenting and rendering data, expressed as distributing a page image, normal rendering, self-containment, selfcontained, and beyond normal rendering. adoption indicates how popular and widely a file format is adopted by user communities, also represented as popularity, widely used formats, ubiquity, or continuity. protection includes the technical protection mechanism or source verification to protect with security skills. preservation means long-term preservation, institutional support, or ease of transformation and preservation. reference indicates citability, or referential extensibility. among other attributes, transparency is interesting to note because it indicates the degree to which files are open to direct analysis with basic tools and human readability. another important aspect across these criteria is that the terminologies used in the studies may be quite different yet describe the same or similar concepts from different angles. for instance, rog and van wijk use openness for standardization and specification without restrictions,36 while examining attributes of open standard file formats for long-term preservation and open access | park and oh 50 several other researchers use open availability to convey the same thing.37 they in turn adopt the term disclosure to express that specification is publicly available.38 discussion and conclusion functionality, metadata, openness, interoperability, and independence appear to be the most important factors when selecting file formats. when file formats for long-term preservation and open access are under discussion, cultural heritage institutions need to consider many issues. despite several efforts, it is still tricky for them to identify the most appropriate file format or even to discern acceptable formats from unacceptable formats. where it is difficult to prevent the creation of a new file format, format selection is not an easy task, both in theory and in practice. it is critical, however, to base the decision on a clear understanding of the purpose for which the document is preserved: access preservation or repurposing preservation. cultural heritage institutions and digital repository communities need to guarantee long-term preservation of digital resources in selected file formats. additionally, users find it necessary to have access to digital information in these file formats. additional consideration involves the level of access users may enjoy (e.g., long-term access, permanent access, open access, persistent access, etc.). when determining international standard file formats, an aspect of open access should be included because it is a well-liked topic. it is necessary to develop a scale or measurement to assess open-standard format specifications to ensure long-term preservation and open access. identifying which attributes are required to be an open-standard file format and which digital format is most apt for the use and sustainability of long-term preservation is a meaningful task. the outcome of our study provides a framework for appropriate strategies when selecting file formats for long-term preservation and access to digital content. we hope that the criteria described in this study will benefit librarians, preservers, record creators, record managers, archivists, and users. we are reminded of todd’s remark that “the most important action is to align the recognition and weighting of criteria with a clear preservation strategy and keep them under review using risk management techniques.”39 the question of how to adopt and implement these attributes can only be answered in the local context and decisions of each cultural heritage institution.40 each institution should consider implementing a file format throughout the entire life cycle of digital resources, with a holistic approach to managerial, technical, procedural, archival, and financial issues for the purpose of long-term preservation and persistent access. the criteria may change over time, as is necessary for any format to adequately serve its purpose. maintaining its quality may be an ongoing task that cultural heritage institutions should take into account at all times. even more importantly, cultural heritage institutions need to establish and implement a set of standard guidelines specific to each context for the selection of open-standard file formats. note: this research was supported by the sungkyunkwan university research fund (2010-2011). information technology and libraries | december 2012 51

libraries | december 2011 hardly a day goes by in my professional life (and it sometimes creeps into my personal life too!) when i don’t think about the issues of connecting people with data, and then how to present that data in ways that are relevant to their needs. the tides are shifting in health sciences library and likely in your library too. ongoing changes in publishing and the changing nature of research have challenged the traditional nature of the library. it is no longer solely a repository for information, physical or virtual. as librarians move from collecting and cataloging bibliographic information new roles have emerged in data discovery, in its preservation, and in helping to make data more accessible. important specialties include; knowledge management, data visualization, e-science and copyright. librarians have valuable skills sets in mining and accessing data, human–computer interaction, computer interface design, and knowledge management that can be leveraged now. it is inevitable that data discovery will quicken the pace of science and lead to collaboration and collaboration will in turn lead to data discovery and accelerate the pace of science and so on and so on. in short twentieth century data stored in individual scientists’ notebooks or computers is largely inaccessible. twenty-first-century data needs to be available 24/7 in a curated state for continuous analysis. information overload and data deluge created by intersection of science and technology are two very real problems that the librarians have the skill and ability to deal with. and, as i talk of science, bear in mind that it extends beyond the biological and physical sciences to encompass the social sciences as well. interdisciplinary studies in particular have intensive data needs. in fields such as public health and urban planning, government data alongside research data is used to predict trends, forecast, make decisions, etc. government data is a particularly important part of the equation. consider the recent nsf requirement for researchers to provide open access to their data for any nsf-sponsored grants. it is likely other government agencies will follow suit. one of taiga’s provocative statements of 2011 is “#10. the oversupply of mlss” which states that “within five years, library programs will have overproduced mlss at a rate greater even than humanities phds and glutted a permanently diminished market.”1 as the alarming scenario of an over abundance of new mlss in proportion to available library jobs presents itself, i encourage librarians to begin to envision themselves as digital information brokers or data scientists. the us department of labor in the 2010–11 occupational outlook handbook, anticipates that librarian jobs in nontraditional settings will grow the fastest over this decade. nontraditional libraries and jobs include working as information brokers for private corporations, nonprofit organizations, and consulting firms. “many companies are turning to librarians because of l ast week i attended the second annual vivo conference in washington, d.c. vivo (vivoweb .org) is a semantic web application that enables the discovery of research and scholarship across disciplines in an institution with the potential to also link scholars and research across institutions. despite an earthquake and a hurricane the conference itself was the real showstopper—excellent, informative programming, engaging speakers, great networking and exchange of ideas. my institution is one of the core vivo members so it was an opportunity to showcase our work, see what others are doing as well as learn more about trends in research, e-science and data discovery and collaboration initiatives. much of what i learned or rediscovered at vivo will make it into my fifty-minute presentation on the subject at the lita national forum in st. louis later this month. in fact the vivo conference itself reminded me of our own national forum in size, scope and content. it was a good mix of in-depth technical discussions coupled with broad coverage of issues and trends in scientific research. this attention to content balance is something that lita consistently gets right at our annual forum—there is literally something for everyone from introductory concepts to technical details—and i look forward to seeing many familiar faces and meeting some new folks at this year’s lita national forum in st. louis “rivers of data: currents of change.” i would also like to take this opportunity to personally invite each and every ital reader to the 2012 lita national forum. building on this year’s theme, the 2012 lita national forum will be “the new world of data: discover. connect. remix.” i just signed off on theme this week and i am excited and impressed by the work completed by the national forum planning committee so far. please look for the call for papers and posters to come out in late december. i love the forum because it is much more intimate than the much larger ala meetings i always come away with new ideas and new friends. i am not alone in this feeling. a recent forum attendee commented,” (the lita forum) was one of the best conferences i have attended. i met a far greater concentration of peers—colleagues at other libraries doing similar work—at lita forum than i have met at other similar conferences.” i don’t think i could say it better myself. the 2012 forum theme is one of great personal interest to me and i plan to extend the theme to the lita president’s program on june 24, 2012, in anaheim. in fact colleen cuddypresident’s message: data discovery colleen cuddy (colleen.cuddy@med.cornell.edu) is lita president 2011–12 and director of the samuel j.

consider: why does ital matter to you? post your thoughts on italica (http://ital-ica.blogspot .com/). s ome time ago i received an e-mail from a library school student, who asked me “why is [ital] important in the library profession?” i answered the question in this way: ital is important to the library profession for at least four reasons. first, while it is no longer the only publication that addresses the use of technology in the library profession, it is the oldest (dating back to 1968, when it was founded as the journal of library automation) and, we like to think, most distinguished. second, not only do we publish on a myriad of topics that are pertinent to technology in libraries, we publish at least three kinds of articles on those subjects: pure scholarly articles that give the results of empirical research done on topics of importance to the profession, communications from practitioners in the field that present real-world experiences from which other librarians can profit, and tutorials on specific subjects that teach our readers how to do useful things that will help them in their everyday jobs. the book and software reviews that are in most issues are added bonuses. third, it is the “official” publication of lita, the only professional organization devoted to the use of information technology in the library profession. fourth, it is a scholarly, peer-reviewed journal, and as such is an important avenue for many academic librarians whose career advancement depends in part on their ability to publish in this type of journal. in a sentence, then, ital is important to the library profession because it contributes to the growth of the profession and its professionals. after sending my response, i thought it would be interesting to see what some other people with close associations to the journal would add. thus i posed the same question to the editorial board and to the person who preceded me as editor. here are some of their comments: one of the many things that was not traditionally taught in library school was a systematic approach to problem solving—for somebody who needs to acquire this skill and doesn’t have a mentor handy, ital is a wonderful resource. over and over again, ital describes how a problem was identified and defined, explains the techniques used to investigate it, and details the conclusions that might fairly be drawn from the results of the investigation. few other journals so effectively model this approach. regardless of the specific subject of the article, the opportunity to see practical problem solving techniques demonstrated is always valuable. (joan frye williams) the one thing i would add to your points, and it ties into a couple of them, is that by some definitions a “profession” is one that does have a major publication. as such, it is not only the “official” publication of lita but an identity focus for those professionals in this particular area of librarianship. in fact, ideally, i would like to think that’s more of a reason why ital is important than just the fact that it’s a perk of lita membership. (jim kopp) real world experiences from which other librarians would profit—to use your own words. that is my primary reason for reading it, although i take note of tutorials as well. and the occasional book review here may catch my eye as it is likely more detailed that what might appear in lj or booklist, and [i would] be more likely to purchase it for either my office or for the general collection. (donna cranmer) ital begins as the oldest and best-established journal for refereed scholarly work in library automation and information technology, a role that by itself is important to libraries and the library profession. ital goes beyond that role to add high-quality work that does not fit in the refereed-paper mold, helping librarians to work more effectively. as the official publication of america’s largest professional association for library and information technology, ital assures a broad audience for important work—and, thanks to its costrecovery subscription pricing, ital makes that work available to nonmembers at prices far below the norm for scholarly publishing. (walt crawford) the journal serves as an historical record/documentation and joins its place with many other items that together record the history of mankind. a professional/scholarly journal has a presumed life that lasts indefinitely. (ken bierman) in a sentence, ital is important to the profession because “communication is the key to our success.” dan marmion was editor of ital, 1999–2004. this editorial was first published in the june 2002 issue of ital. 168 information technology and libraries | december 2010 to paper. ital provides one means of fostering this communication in a format that is easily usable and recognizable. it is not the only communications format, but it fills a particular niche. (eric lease morgan) so there you have the thoughts of the editor and a few other folks as to why this journal is important. * * * why does ital matter to you? post your thoughts on italica (http://ital-ica.blogspot.com/). ital is a formal, traditional, and standardized way of sharing ideas within a specific segment of the library community. librarianship is an institutional profession. as an institution it is an organic organization requiring communication between its members. an advantage of written communication, especially paper-based written communication, is its ability to transcend space and time. a written document can communicate an idea long after the author has died and half way around the world. yes, electronic communication can do the same thing, but electronic communication is much more fragile than ideas committed 60 information technology and libraries | june 2011 b ecause this is a family program and because we are all polite people, i can’t really use the term i want to here. let’s just say that i am an operating system [insert term here for someone who is highly promiscuous]. i simply love to install and play around with various operating systems, primarily free operating systems (oses), primarily linux distributions. and the more exotic, the better, even though i always dutifully return home at the end of the evening to my beautiful and beloved ubuntu. in the past year or two i can recall installing (and in some cases actually using) the following: gentoo, mint, fedora, debian, moonos, knoppix, damn small linux, easypeasy, ubuntu netbook remix, xubuntu, opensuse, netbsd, sabayon, simplymepis, centos, geexbox, and reactos. (aside from stock ubuntu and all things canonical, the one i keep a constant eye on is moonos [http://www.moonos.org/], a stunningly beautiful and eminently usable ubuntu-based remix by a young artist and programmer in cambodia, chanrithy thim.) in the old days i would have rustled up an old, sloughed-off pc to use as an experimental “server” upon which i would unleash each of these oses, one at a time. but those were the old days, and these are the new days. my boss kindly bought me a big honkin’ windows-based workstation about a year and a half ago, a box with plenty of processing power and memory (can you even buy a new workstation these days that’s not incredibly powerful, and incredibly inexpensive?), so my need for hardware above and beyond what i use in my daily life is mitigated. specifically, it’s mitigated through use of virtual machines. i have long used virtualbox (http://www.virtualbox .org/) to create virtual machines (vms), lopped-off hunks of ram and disk space to be used for the installation of a completely different os. with virtualbox, you first describe the specifications of the vm you’d like to create—how much of the host’s ram to provide, how large a virtual hard disk, boot order, access to host cd drives, usb devices, etc. you click a button to create it, then you install an os onto it, the “guest” os, in the usual way. (well, not exactly the usual way; it’s actually easier to install an os here because you can boot directly from a cd image, or iso file, negating the need to mess with anything so distasteful and old-fashioned and outre as an actual, physical cd-rom.) in my experience, you can create a new vm in mere seconds; then it’s all a matter of how difficult the os is to install, and the linux distributions are becoming easier and easier to install as the months plow on. at any rate, as far as your new os is concerned, it is being installed on bare metal. virtual? real? for most intents and purposes the guest os knows no difference. in the titillatingly dangerous and virus-ridden cyberworld in which we live, i’ll not mention the prophylactic uses of vms because, again, this is a family program and we’re all polite people. suffice it to say, the typical network connection of a vm is nated behind the nic of the host machine, so at least as far as active network– based attacks are concerned, your guest vm is at least as secure as its host, even more so because it sits in its own private network space. avoiding software-based viruses and trojans inside your vm? let’s just say that the wisdom passed down the cybergenerations still holds: when it rains, you wear a raincoat—if you see what i’m saying. aside from enabling, even promoting my shameless os promiscuity, how are vms useful in an actual work setting? for one, as a longtime windows guy, if i need to install and test something that is *nix-only, i don’t need a separate box with which to do so. (and vice versa too for all you unix-weaned ladies and gentlemen who find the need to test something on a rocker from redmond.) if there is a software dependency on a particular os, a particular version of a particular os, or even if the configuration of what i’m trying to test is so peculiar i just don’t want to attempt to mix it in with an existing, stable vm, i can easily and painlessly whip up a new instance of the required os and let it fly. and deleting all this when i’m done is easily accomplished within the virtualbox gui. using a virtual machine facilitates the easy exploration of new operating systems and new applications, and moving toward using virtual machines is similar to when i first started using a digital camera. you are free to click click click with no further expense accrued. you don’t like what you’ve done? blow it away and begin anew. all this vm business has spread, at my home institution, from workstation to data center. i now run both a development and test server on vms physically sitting on a massive production server in our data center—the kind of machine that when switched on causes a brown-out in the tri-state area. this is a very efficient way to do things though because when i needed access to my own server, our system administrator merely whipped up a vm for me to use. to me, real or virtual, it was all the same; to the system administrator, it greatly simplified operations. and i may joke about the loud clank of the host server’s power switch and subsequent dimming of the lights, but doing things this way has been shown to be more energy efficient than running a server farm in which each server editorial board thoughts: just like being there, or how i learned to stop coveting bare metal and learned to love my vm mark cyzyk (mcyzyk@jhu.edu) is the scholarly communication architect in the sheridan libraries, johns hopkins university, baltimore, maryland. mark cyzyk editorial board thoughts | cyzyk 61 virtual machines: zero-cost playgrounds for the promiscuous, and energy efficient, staff saving tools for system operations. what’s not to like? throw dual monitors into the mix (one for the host os; one for the guest), and it’s just like being there. sucks in enough juice to quench the thirst of its redundant power supplies. (they’re redundant, they repeat themselves; they’re redundant, they repeat themselves—so you don’t want too many of them around slurping up the wattage, slurping up the wattage . . . ) letter from the editor kenneth j. varnum information technology and libraries | december 2017 1 https://doi.org/10.6017/ital.v36i4.10237 i am excited to have been appointed editor of information technology and libraries as the journal enters its 50th year. originally published as the journal of library automation, ital has a long history of tracking the rapid-fire changes in technology as it relates to libraries. much as it has over the past 50 years, technology will continue to change not just the way libraries offer services to their communities, but the way we conceptualize what it is we do. if past is prologue, i have no doubt the next decades will continue to amaze, probably in ways even the most adventurous trend-forecaster won’t get quite right. in the context of the rapid change in how we do our work, what we do will remain the same: collecting, preserving, and providing access to the information and artefacts of our culture, whatever that may be. i would like ital to grow and expand, while keeping its core essence the same. that core is high-quality, relevant, and informative articles, reviewed by our peers, and made available to the world. but i think there is more we can do for lita and the library technology profession by expanding the scope and impact of the journal through seeking and soliciting articles from a wider range of librarians, adding more case studies to the research articles that are at the journal’s core, and being more rapidly responsive to the evolving technology landscape in front of us. to that end, i invite you to think broadly about researching, documenting, and describing the technology-related work you do so that others can learn about it. i welcome questions about how your project might fit into ital, and look forward to working with you. i’d like to close by extending my thanks to bob gerrity, who served as ital’s editor for the past 6 years and stewarded the journal’s transition to an open access publication. i am grateful for his service to ital, lita, and the profession. sincerely, kenneth j. varnum editor varnum@umich.edu mailto:varnum@umich.edu 2 information technology and libraries | march 2011 program

enhance their skills. in 2009, emerging leaders team t developed a project “making it personal: leadership development programs for lita,” working in consultation with the lita membership development committee. team members included amanda hornby (university of washington), angelica guerrero fortin (san diego county library), dan overfield (cuyahoga community college), and lisa carlucci thomas (yale university). the team t members recommended the creation of “an online continuing education program to develop the leadership and project management skills necessary to maintain and promote the value and ability of lita’s professional membership to the greater librarian population.” outcomes for the training would include project-management and team-building skills within a context that focuses on the development and application of technology in libraries. the team members also recommended the establishing of a lita mentorship karen j. starr (kstarr@nevadaculture.org) is lita

libraries | june 2019 37 sharon han (shrnhan@gmail.com) is candidate for master of science in library and information science, school of information sciences, university of illinois. abstract after a disaster, news reports and online platforms often document the swift response of public libraries supporting their communities. despite current scholarship focused on social media in disasters, early uses of social media as an extension of library services require further scrutiny. the federal emergency management agency (fema) recognized hurricane sandy as one of the earliest u.s. disasters in which first responders used social media. this study specifically examines early uses of twitter by selected public libraries as an information tool during sandy’s aftermath. results can inform uses of social media in library response to future disasters. introduction in the digital age of instantaneous communication, when disasters hit, they hit us all. the fall and winter of 2017-18 brought a literal and figurative deluge to our screens with the arrival of hurricanes harvey, irma, and maria to the united states. within moments of each event, websites and news feeds filled with images of destruction and cries for help. the use of social media to bring awareness to victims’ situations through hashtags and directly tagging first responders underscores the importance of this technological tool in the twenty-first century. in fact, the ubiquity of social media in documenting hurricane harvey have led some to believe that it should be considered the first “social media storm.”1 however, many of the most popular social media platforms have existed since the mid-2000s and have already been used to communicate disasterrelated information since well before harvey reached the united states’ shores. some of social media’s earliest adapters were even public libraries who had the resources and means to use this information technology as a method of connecting with their communities. why should social media matter to public libraries in times of disaster? as a physical manifestation of information access, the public library maintains a relationship with its community that varies across regions, time, and context. currently, the public library as an entity is in an interventionist period, according to jaeger’s article “libraries, policy, and politics in a democracy: four historical epochs,” where its roles and responsibilities are heavily influenced by outside factors, especially the federal government.2 from tax forms to permits to insurance claims, the government encourages people to use the public library to find and use information necessary to navigate american society. public demand for accessing government and other resources is especially apparent after natural disasters, which, due to their unpredictable nature, can heighten weathering the twitter storm | han 38 https://doi.org/10.6017/ital.v38i2.11018 community uncertainty and the need for credible and reliable information. public libraries can meet this information need by using social media as one strategy to assess and provide resources in real time. when hurricane sandy landed on new jersey’s shore on october 29, 2012, it prompted a new era for societal response to emergencies and community needs. due to the hurricane’s trajectory into densely populated areas of the american northeast and subsequent widespread flooding, hurricane sandy was the deadliest storm of 2012.3 with initial estimated recovery costs of up to $50 billion, the degree of damage to buildings, infrastructure, and endangerment of people’s safety made swift and coordinated communication paramount in response efforts. thus, the aftermath of hurricane sandy resulted in federal agencies using social media for the first time in coordinating and implementing disaster response.4 as community-based service providers, many public libraries responded to the hurricane by sharing available resources and services with patrons. however, few studies explicitly examine the use of social media as a library tool to support their community. this paper explores the role of social media and its impact on public library services in response to hurricane sandy as a measure of libraries using digital mediums to support their communities. using twitter posts from three separate public libraries impacted by the hurricane, their content is analyzed and compared to reported library services after the storm. the analysis will then be used to discuss the use of social media as a library tool and recommendations for social media implementation in future disaster response. background information library response to disasters according to the institute of museum and library services’ public library data from 2009 to 2011, over half of all public libraries are located within declared “disaster counties.”5 this value implicates disaster response as an important topic within public librarianship discourse. in addition to assessing damages to buildings and collections, libraries must also meet the needs of its community. information needs are heightened after a disaster, as the destruction results in information uncertainty and loss of important resources such as power and telecommunication services.6 consistent and increased use of public libraries is not unusual post-disaster. for example, despite 35 percent of louisiana libraries being closed after hurricane katrina in 2004, a study found that overall library visitor counts only decreased by 1 percent.7 frequent use of library resources after a disaster can be attributed to the library’s free and low-cost resources, as well as the institution’s reputation as a source for reliable and credible information.8 libraries also extend their resources and services beyond their walls. library bookmobiles and delivery programs provide services to those who are unable to physically visit the library. some libraries use their skills in information management and communication to assist local disaster preparedness groups and response teams.9 in 2011, the federal emergency management agency (fema) declared public libraries eligible for temporary relocation funds in the event of an emergency, a distinction once limited to first responders, hospitals, utilities, and schools.10 former executive director of the american library association’s (ala) washington office, emily sheketoff, stated such a distinction recognizes libraries as “essential community organizations.”11 in context with jaeger’s interventionist period, it benefits libraries and government agencies alike to have libraries open to serve communities after a disaster. information technology and libraries | june 2019 39 in the aftermath of hurricane sandy, communities suffered from varying degrees of damage, such as flooding, power outages, debris, and downed trees.12 the impact of the storm drove many community members to their local libraries to seek shelter, charge their electronics, file insurance claims and other e-government forms, drop off or pick up donations, and obtain entertainment.13 despite the many stories of libraries serving disaster victims and working with first responders, such actions have yet to be translated into widespread library policy and procedures. ala provides a “disaster preparedness and recovery” resources webpage, but it primarily focuses on addressing material and structural needs after a disaster, such as mitigating water damage to collections.14 other studies also note a majority of library disaster response literature remains focused on protecting materials.15 such a limited perspective is highlighted in a national survey in which the majority of librarian respondents believed protecting library materials and performing daily services were their primary goals in the event of an emergency.16 as a result, library communication with the community and local organizations remains a relatively unexplored subject in context with disaster response.17 while trade journals and websites publish stories of individual libraries serving their communities, formal studies and research are comparatively scarce. with the widespread use of technology and the internet, one method of communication stands out as an important tool for library outreach and study: social media. disaster response through social media as information providers and advocates of communication technology, libraries should use social media to connect with their communities. although libraries were early adopters of social media prior to hurricane sandy, their use of these tools tends to focus on one-way information sharing instead of a dialogue with their community.18 social media in context of disaster response may upend traditional library social media use, which is why this topic needs further examination. social media coupled with mobile technology has created a society in which information sharing and communication are constant and instantaneous.19 since social networking is a relatively new form of media, formal studies on its impact on social behaviors have only come about in the last decade.20 within this young body of literature, however, social media use in disaster response and recovery is a popular topic for researchers, organizations, and federal agencies.21 alexander claims that social media provides the following benefits during disaster response: • provides an outlet to listen and share thoughts, emotions, opinions; • monitors a situation; • integrates social media into emergency plans; • crowdsources information; • creates social cohesion and promoting therapeutic initiatives; • furthers causes; and • creates research data.22 such a comprehensive list is beneficial to this study because it provides a framework through which library social media use can be examined. these benefits stem from the sharing of information with people or entities, which is a large component of library disaster response, as discussed in the previous section. using alexander’s list as a reference, the three main benefits this study examines in context with library disaster response are: weathering the twitter storm | han 40 https://doi.org/10.6017/ital.v38i2.11018 1. monitors a situation. a survey of library patrons impacted by the 2015 south carolina floods revealed all respondents used social media to learn about the flooding and impacted areas.23 people now frequently use social media to get updates on situations, whether they were directly or indirectly impacted by the natural disaster itself. disaster response groups also monitor social media feeds to assess and allocate resources to those in need.24 libraries can use social media feeds to assess resources and services use, plan outreach opportunities, and even inform the public about its own status during the disaster. 2. integrates social media into emergency plans. social media is a low-cost and effective way to coordinate disaster response between organizations and people. much like bookmobiles, social media serves as outreach for librarians to improve service accessibility. librarians can use platforms like twitter and facebook to help coordinate their activities and services alongside with other responders in the community. having an established plan of action where the library’s role and responsibilities are clearly outlined will result in more effective service and efficient response to community needs.25 3. creates social cohesion and promoting therapeutic initiatives. in alignment with the library’s mission of creating and serving communities, social media can act as an extra method of fostering connections in times of need. disaster victims can take advantage of social media’s speed and ubiquity to check in with family, tell them they are safe, and participate in relief efforts.26 social cohesion through platforms such as twitter can also create participatory discourse between people and organizations. for example, then-fema administrator chris furgate’s recommendation to read to children during the hurricane prompted the hashtag #stormreads to trend on twitter, as many accounts—libraries included—shared their recommended titles.27 library use of social media can also address growing concerns about rumors and misinformation spread during disasters.28 as providers of reliable and accurate information, libraries help establish source credibility and push more accurate resources to misinformed and unaware community members. although there is a substantial amount of research focused on libraries responding to disasters and social media use during disasters separately, there is a gap in library science literature examining social media as a method of library disaster response. interestingly, formal studies that mention library disaster response note an explicit absence of social media as a form of emergency communication.29 despite the current dearth, library social media studies can develop quickly thanks to the abundant amount of data available on social media platforms. as libraries continue to respond to disasters, they will require more deliberate and planned use of social media as a communication tool. such a need demands a closer examination of how libraries have historically used social media during disasters. case studies: three public libraries and twitter this study will examine the social media feeds of three public libraries during and immediately after hurricane sandy landed on the northeastern coast as a measure of social media’s impact on communication and information-sharing amongst libraries, patrons, and first responders. due to its frequent use for sharing up-to-date information, twitter was the selected social media platform to study.30 the public library systems were selected for this analysis based on their varying characteristics and available literature describing their actions after the hurricane. new york information technology and libraries | june 2019 41 public library (nypl, @nypl), princeton public library (ppl, @princetonpl), and queens library (ql, @queenslibrary) have twitter accounts that were at least two years old by october 2012. all accounts were active during the time period of interest, although they were closed when hurricane sandy landed. nypl and ql were closed an additional two days due to damages to several branch libraries.31 these library systems serve varied communities. nypl and ql are urban libraries located in new york city, with 91 and 62 branches respectively, and ppl is a one branch library located in downtown princeton, new jersey. the larger library systems reported flooding and power outages at several branches from the hurricane, while ppl sustained no structural or internal damages.32 however, all library systems were in communities where large numbers of households lost electricity and internet access, and sustained damages from fallen trees and flooding.33 the library systems were mentioned in news reports for services to library patrons affected by the storm, including providing charging stations for electronics, helping people fill out fema insurance forms, running programs for children and adults, and having public computers and wireless connections to access the internet.34 the libraries’ coupled use of twitter and active provision of disaster response services make them ideal candidates for examining the correlation between the two activities. methodology this study used a filtered search on twitter to identify tweets from each library’s feed within the time period of interest. within searches, each tweet was recorded and categorized based on content and message format. a single tweet could have more than one category. common content subcategories were identified to improve analysis. defined categories are as follows: • hurricane information: information on the hurricane’s status and impact from news and government agencies. • library policies: information on library policies. • library policies, renewals/fines: information on renewals and fines during the studied time period. • library status: information on library branch closures. • library event/service related to hurricane: event or service specifically planned in response to hurricane. • library event/service not related to hurricane: regular library programming; included event/service cancellations as an indirect/direct result of hurricane. • non-library event/service related to hurricane: information on non-library sponsored events and services provided in response to the hurricane. • replies: a publicly posted message from the library to another twitter user. • social interactions: non-informative and informative tweets aimed at conversing with people or organizations in a social manner. selected categories were then associated with a corresponding benefit from three of alexander’s defined benefits (table 1).35 after categorizing, the collected data was organized for analysis and comparison. weathering the twitter storm | han 42 https://doi.org/10.6017/ital.v38i2.11018 table 1. categories organized by social media benefits.36 benefit twitter content categories

followers. tweet frequencies were counted and compared over the fiveday period across libraries (figure 1). while nypl and ql averaged almost 11 tweets per day, ppl had nearly double their numbers, at about 18 tweets per day. nypl and ql had a generally increasing trendline in tweets, while ppl’s twitter use fluctuated greatly. nypl and ql’s low tweet count during the studied time frame may be attributed to library-wide closures, although only ql’s tweet count increased significantly upon reopening. figure 1. number of tweets per day by library. content analysis illustrated variations in twitter use across all three libraries (figure 2). nypl tweeted the most about their library status and renewal/fine policy, with 21 and 17 tweets, information technology and libraries | june 2019 43 respectively. ppl focused more on advertising library events and services such as electrical outlets, heat, internet, and entertainment. they also used twitter heavily for social interactions, 35 percent of ppl’s 112 tweets, including asking questions, recommending books, thanking concerned patrons, and even apologizing for retweeting too many news articles about the hurricane. ql’s twitter use was more of a mix, often posting about library status and socially interacting with other twitter users. figure 2. twitter content by library. each library also differed in least common content tweeted. nypl had the fewest tweets about the hurricane, non-library services and events related to the hurricane, other library policies, and social interactions. ppl also had few tweets with information about the hurricane and rarely tweeted about fines and renewals. ql had no tweets about the hurricane, nor did they tweet about any library events or programs that were unrelated to their disaster response. discussion the data collected was analyzed to determine whether each library fulfilled the three identified benefits of social media that directly relate to the library’s mission of information access and community building: monitoring a situation, integrating social media into emergency plans, and creating social cohesion and promoting therapeutic initiatives. each library’s consistent responses to twitter users, status updates, and information about library services illustrates they all monitored their communities’ situations and responded accordingly through services and programs, as evidenced in news reports. libraries also used twitter to engage with others and weathering the twitter storm | han 44 https://doi.org/10.6017/ital.v38i2.11018 create a social network of library patrons and local institutions. based on the lack of information about the storm itself and few recommendations for non-library disaster response group resources, it is not apparent libraries integrated social media as part of their emergency policy and procedures. this also resulted in a dissonance between library action and their online communication. one notable example: many news reports described librarians aiding patrons with finding and filling out fema insurance forms, but only one of the 196 tweets analyzed in this study advertised fema assistance at the library.37 ppl tweeted several posts illustrating library use by affected patrons, but also emphasized they were at capacity due to large visitor numbers and shortages in charging stations and internet bandwidth. ppl also failed to offer alternatives on twitter to meet patron information needs. the lack of a coordinated effort perhaps can be explained in two parts. first, as no two disasters are alike, library response is often a direct reaction to the event and damages to their institution and community. a busy library would logically place social media communication and coordination as a lower priority than other immediate, tangible needs. second, librarians may not make a concerted effort to use social media if they are trained to prioritize protecting library collections and conducting regular services.38 while digital and outreach services such as bookmobiles have been common components of libraries, there is still a noticeable gap in libraries extending these same services using online tools. the libraries in this study used social media as a part of their disaster response, but the lack of planning resulted in each library’s twitter feed acting more as a “triage center,” providing basic assistance as the need arose, rather than an extension of in-house services. takeaways and further research while these libraries provided much needed services in the aftermath of hurricane sandy, their implementation of social media as a communication and information-sharing tool illustrates opportunities to develop more coordinated efforts. as library presence on and use of social media continues to grow, it should be considered as a necessary component of library disaster response and collaboration with other government agencies and first responders. while libraries are qualified for fema funding, it is uncertain that local first responder groups are aware of the services and benefits libraries provide post-disaster at all. as of 2013, the u.s. department of homeland security’s virtual social media working group did not include any library organizations, which leaves libraries out of crucial conversations in designing comprehensive disaster response plans.39 in an effort to participate in productive discourse, librarians also need to improve their social media use to better align with their practice when serving distressed communities. while the exact reasons for librarians’ lack of effective social media use in disaster response remains speculative, other research has shown that training opportunities for social media use in libraries remain scarce and not very effective.40 since hurricane sandy, social media has only grown as a powerful tool for people and communities, rendering it an essential skill for librarians today. this should motivate librarians, library associations, and other professional groups to consider developing effective training and workshops geared towards intentional use of social media. despite its power, social media should be seen as a complementary tool to enhance information services for community members. it will optimize the library’s reach, but it cannot completely replace current methods of outreach, nor should it. this is especially important when considering information technology and libraries | june 2019 45 who benefits the most from libraries, many of whom do not necessarily have consistent access to social media.41 social media use varies across age, socioeconomic status, digital access, and education levels, making it important for librarians to consider whose information needs are and are not being met online. considering such limitations, learning impactful social media skills and creating a support network amongst disaster response groups will enable libraries to effectively develop outreach strategies and improve disaster response services. the discussion and takeaways highlight the necessity for further research on social media use in library disaster response. as the history of library development and service informs the direction of libraries today, so too should historic uses of social media as a library service tool guide future work. continuing research may include case studies of public library response to recent disasters, which would provide better insight into the developing use of social media. the identified patterns and strengths can be used to guide future work in incorporating effective social media policies and protocols in library disaster plans. considering social media usage by first responders and federal agencies, future research should also include a closer examination of relationships between public libraries, first responders, and disaster information providers in improving coordinated response efforts. conclusion when disaster strikes, many communities exhibit a great need for resources and information. despite libraries providing much needed service and resources to community members after natural disasters, their use of social media platforms as a tool remains overlooked. this study examines historical use of social media as a communication and service tool between libraries, community members, and disaster response groups in the aftermath of hurricane sandy. the effectiveness of social media use was evaluated using alexander’s review of social media benefits and compared with descriptions of post-sandy library resources and services described in the literature. the study found social media use to be highly variable based on content and correlations with reported in-house library services. there was no sign of a coordinated effort with other disaster response groups, and the primary objective of their twitter accounts was connecting with patrons and other organizations through social interactions. improvements to social media use could be achieved through intentional coordination with first responders, directed training, and evaluating social media’s strengths and limitations in disaster response. if libraries wish to continue providing pertinent information, they need to adapt to communication methods used by their community. with social media’s strong presence in society, suburban and urban libraries such as the ones examined in this study should improve their use of social media as an effective information sharing and communication tool. continuing to examine and assess uses of social media as a disaster response tool can help shape policies and procedures that will enable libraries to better serve their communities. references

for authority control in libraries article beyond viaf wikidata as a complementary tool for authority control in libraries carlo bianchini, stefano bargioni, and camillo carlo pellizzari di san girolamo information technology and libraries | june 2021 https://doi.org/10.6017/ital.v40i2.12959 abstract this paper aims to investigate the reciprocal relationship between viaf® and wikidata and their possible roles in the semantic web environment. it deals with their data, their approach, their domain, and their stakeholders, with particular attention to identification as a fundamental goal of universal bibliographic control. after examining interrelationships among viaf, wikidata, libraries and other glam institutions, a double approach is used to compare viaf and wikidata: first, a quantitative analysis of viaf and wikidata data on personal entities, presented in eight tables; and second, a qualitative comparison of several general characteristics, such as purpose, scope, organizational and theoretical approach, data harvesting and management (shown in table 9). quantitative data and qualitative comparison show that viaf and wikidata are quite different in their purpose, scope, organizational and theoretical approach, data harvesting, and management. the study highlights the reciprocal role of viaf and wikidata and its helpfulness in the worldwide bibliographical context and in the semantic web environment and outlines new perspectives for research and cooperation. introduction in 2011, the library linked data incubator group, a w3c working group with the aim “to help increase global interoperability of library data on the web,” published its final report. two interrelated issues were tackled in that milestone report: what libraries can do for the semantic web and what the semantic web can do for libraries. linked data is an important asset for libraries as the “use of identifiers allows diverse descriptions to refer to the same thing. through rich linkages with complementary data from trusted sources, libraries can increase the value of their own data beyond the sum of their sources taken individually.”1 so linked data greatly contribute to library cataloguing work not just for description of resources but also for their proper identification. on the other hand, libraries have always created and curated a significant amount of valuable information assets and library authority data for names and subjects to help reduce “redundancy of bibliographic descriptions on the web by clearly identifying key entities that are shared across linked data. this will also aid in the reduction of redundancy of metadata representing library holdings.”2 the report opened a new way of thinking about universal bibliographic control (ubc), a “worldwide system for control and exchange of bibliographic information,” (https://archive.ifla.org/ubcim/ubcim-archive.htm) the purpose of which is “to make universally carlo bianchini (carlo.bianchini@unipv.it) is associate professor, department of musicology and cultural heritage, university of pavia. stefano bargioni (bargioni@pusc.it) is deputy director, library of the pontifical university santa croce (rome). camillo carlo pellizzari di san girolamo (camillo.pellizzaridisangirolamo@sns.it) is graduate student, department of classics, university of pisa and scuola normale superiore. © 2021. https://archive.ifla.org/ubcim/ubcim-archive.htm mailto:carlo.bianchini@unipv.it mailto:bargioni@pusc.it mailto:camillo.pellizzaridisangirolamo@sns.it information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 2 and promptly available, in a form which is internationally acceptable, basic bibliographic data on all publications in all countries.”3 exchanging information and data requires standards, at both the national and international level, for description, identification, and data format. nowadays, a pillar of ubc is viaf® (the virtual international authority file), a worldwide project designed by a few national libraries and run by oclc, which combines multiple name authority files with the goal “to lower the cost and increase the utility of library authority files by matching and linking widely-used authority files and making that information available on the web [https://www.viaf.org/].” it “clusters together the various forms of names for an entity” and has become “a major source for authority control and is becoming the collective reference source at the international level.”4 viaf is a fundamental tool for the identification of entities (people, locations, works, and expressions) relevant for the bibliographic universe. yet, as it is based on the harvesting of data from authoritative national libraries spread all over the world, it has a top-down approach: libraries and services that are not viaf sources can only refer to viaf, but not actively cooperate with it, and, for its nature, viaf cannot admit user cooperation. therefore, on a global scale, a very large number of local libraries are excluded, and their data, collections, and specificities are, too. furthermore, since the design and development of viaf at the beginning of the 21 st century, the semantic web environment has hugely evolved, and libraries are more and more required to act in new directions and to explore new forms of cooperation.5 illien and bourdon maintain not only that libraries “must now be careful to keep up their own interoperability,” but also that they “would be well-advised to keep up or enter into dialogue with the most influential communities in the web of data—smoothing out their own disputes in the meantime.”6 moreover, they believe that “building collaborative authority registries linked to standardized identifiers is one of the fundamental cornerstones of the new universal bibliographic control.”7 also, dunsire and willer suggest that a “smart ubc should strive to support all those who wish to think globally and act locally, with a better mix of bottom-up and top-down methodologies” as far as the “attempts to implement ubc as a worldwide system for the control and exchange of bibliographic information using top-down methodologies have only partially succeeded at global scale.”8 as a result, a better integration of libraries into the semantic web seems to require the involvement of a larger group of stakeholders—such as non-national agencies, museums, archives, and users—and the adoption of a complementary bottom-up approach. a new global actor of the semantic web has both a bottom-up and a very inclusive approach: wikidata. wikidata is a freely available hosted platform that anyone—including libraries—can use to create, publish, and use linked open data (lod). since 2012, many users have been involved in a bottom-up approach to identity management in wikidata. furthermore, interest in and experience with the use of wikidata to publish lod among glam (galleries, libraries, archives, and museums) institutions is constantly increasing.9 the wikidata role as an important tool for the identification of entities of any kind —not just those of traditional importance to glam—has likewise been increasingly recognized in recent years.10 https://www.viaf.org/ information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 3 so, two worldwide identification tools, two different backgrounds, two opposite approaches. are they mutually exclusive, or integrable? is one of them sufficient for libraries’ needs, or do libraries need both? which stakeholders are best served by viaf? which are best served by wikidata? this paper investigates the reciprocal relationship between viaf and wikidata and of their possible specific roles in the semantic web environment with respect to their approach, their domain, and their stakeholders, with particular attention to identification as a fundamental goal of ubc. relationship between viaf and libraries viaf gathers a huge quantity of authority data from more than 50 sources, listed in the home page of the project (https://viaf.org). millions of records coming from national libraries and other institutions are continuously processed using algorithms based on the matching of data and bibliographic relationships with the goal of creating clusters of names (figure 1).11 figure 1. viaf cluster for wolfgang amadeus mozart clusters are usable in many services “to identify names, locations, works, and expressions while preserving regional preferences for language, spelling, and script” (https://www.oclc.org/en/viaf.html). clusters may contain one or more ids from viaf sources. furthermore, unique identifiers of clusters (a viaf id, e.g., https://viaf.org/viaf/7524651/) are freely reusable and reused by other institutions to add useful information to their catalogues, open up new paths of information for the end user, contribute local data to the linked data cloud, and much more.12 https://viaf.org/ https://viaf.org/viaf/32197206/ https://www.oclc.org/en/viaf.html https://viaf.org/viaf/7524651/ information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 4 data sources are selected and approved by the viaf council (see https://www.oclc.org/en/viaf/contributing.html), and may belong to two categories: viaf contributors, usually national lam (libraries, archives, museums) agencies, admitted following very selective criteria; and other data providers, i.e., “other selected sources (e.g., wikipedia [sic]) that are not viaf contributor agencies.”13 other data providers include isni and wikidata (even if wikidata is often confused with wikipedia, as in the quotation above).14 while contributors are eligible to appoint a representative to the viaf council, other data providers are not. so, viaf is based on a rigid three-level hierarchical approach: viaf, viaf contributors, and other data providers. all the other national and local institutions, i.e., relevant national data producers that are no t national agencies, cannot provide data to viaf; instead, they are expected to benefit from the use of viaf ids after performing a reconciliation process of their own data with viaf ids. however, benefits could be not completely satisfactory in term of quality of data: while viaf deals with “widely-used authority files,” it can be supposed that the libraries of non-national agencies need authority data more relevant on a local or specialistic basis. lastly, while viaf guidelines state that viaf participants should periodically send updated data to viaf, it is not clear when and how viaf retrieves and collects data from other data providers (https://www.oclc.org/content/dam/oclc/viaf/viaf%20guidelines.pdf). relationships between wikidata and academic, research, and public libraries wikidata was launched in 2012 by the wikimedia foundation as the central storage of the structured data from all wikimedia foundation projects; it is “a freely available hosted platform that anyone—including libraries—can use to create, publish, and use lod.”15 wikidata stores stable and common information about entities, i.e., items and properties, and interlinks between different wikimedia projects, in a form compliant with the rdf model (see https://www.mediawiki.org/wiki/wikibase/datamodel/primer). additionally, wikidata uses triples and enriches them with qualifiers and references.16 qualifiers allow adding specifications about the validity of a statement (start/end date, precision, obsolescence, series ordinal, etc.); references are fundamental to justify the data, i.e., to document the authority data creator’s reason for choosing the name or form of name on which a controlled access point is based. 17 wikidata uses the software wikibase (https://wikiba.se/), which is “an open-source software suite for creating collaborative knowledge bases” whose “data model prioritizes language independence and knowledge diversity.” the wikibase open-source software, which is currently used by more than thirty institutions, supports federated sparql queries. 18 wikibase’s approach and characteristics are particularly interesting for the library world. gemeinsame normdatei (gnd) created a working group with wikimedia deutschland in order to “debate whether wikibase is suitable for the needs of existing authority files coming from libraries” (https://wiki.dnb.de/display/gnd/authority+control+meets+wikibase); in march 2020 it was stated that the cooperation “has proven successful” and the current aim is to “develop a wikibasebased gnd and put it into use” (https://wiki.dnb.de/pages/viewpage.action?pageid=167019461). similarly, the bibliothèque nationale de france (bnf) and the agence bibliographique de l'enseignement supérieur (abes) launched the joint french national entities file (fne), which in 2019 carried out “a proof of concept to investigate the feasibility of using the software https://www.oclc.org/en/viaf/contributing.html https://www.oclc.org/content/dam/oclc/viaf/viaf%20guidelines.pdf https://www.mediawiki.org/wiki/wikibase/datamodel/primer https://wikiba.se/

bargioni, and pellizzari di san girolamo 5 infrastructure of wikibase to support the fne.”19 a synthesis of the proof of concept, published in july 2020, mentioned, among the decisions taken, the choice to develop fne to build on wikibase (https://www.transition-bibliographique.fr/wp-content/uploads/2020/07/synthese-preuveconcept-fne.pdf). fne is scheduled to be launched in the next few years (https://f.hypotheses.org/wpcontent/blogs.dir/2167/files/2020/02/20200128_8_versunfichiernationaldentites.pdf ). even more interestingly, between 2017 and 2018, oclc explored a linked data wikibase prototype; the final report shows, among other results, that “the building blocks of wikibase can be used to create structured data with a precision that exceeds current library standards” and that “to populate knowledge graphs with library metadata, tools that facilitate the import and enhancement of data created elsewhere are recommended [. . . and . . .] the pilot underscored the need for interoperability between data sources, both for ingest and export.”20 in late 2019, the ifla wikidata working group was formed “to explore and advocate for the use of and contribution to wikidata by library and information professionals, the integration of wikidata and wikibase with library systems, and alignment of the wikidata ontology with library metadata formats such as bibframe, rda, and marc” (https://www.ifla.org/node/92837). on the wikimedia side, in 2019 the ld4-wikidata affinity group (ld4 stands for “linked data for”) was created by hilary thorsen, wikimedian in residence at stanford university, to understand “how the library can contribute to and leverage wikidata as a platform for publishing, linking, and enriching library linked data” (https://wiki.lyrasis.org/display/ld4p2/ld4wikidata+affinity+group). libraries’ interest in wikidata is usually focused on lod and semantic discovery, not on authority control: “libraries may each use different, unique, or select identifiers and authority control methods for disambiguation. increasingly, wikidata is becoming an important tool for synchronizing across identifiers like virtual international authority file (viaf) and orcid identifiers. integrating awareness of wikidata and its uses for enhancing metadata and link ed open data will help advance a more interconnected research web.”21 identification is a key issue both in bibliographic control and in the semantic web environment, as john riemer noted: “recent examination of the efforts involved in what we have historically called authority control in the pcc community has led us to the conclusion that the primary emphasis should be on identity management.”22 as a matter of fact, wikibase and wikidata’s approach to authority control and bibliographic description is quite new: not only does the traditional distinction between authority and bibliographic data disappear in a wikibase description, but wikidata is to be considered firstly as an identity management tool for any kind of entity.23 relationship between viaf and wikidata the first attempt of cooperation between viaf and wikidata goes back to 2012, when maximilian klein and alex kyrios, wikipedians in residence at oclc and the british library, respectively, developed a project to integrate authority data from the viaf with english wikipedia biographical articles. the project successfully “added authority data to hundreds of thousands of articles on the english wikipedia,” but above all showed that “linking of data represents an opportunity for libraries to present their traditionally siloed data, such as catalogue and authority records, in more openly accessible web platforms.”24 at the time, wikidata was taking its first steps, but later authority data were successfully transferred from english wikipedia to wikidata. https://www.transition-bibliographique.fr/wp-content/uploads/2020/07/synthese-preuve-concept-fne.pdf

information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 6 at present, the connection between wikidata and viaf is very strong. both viaf and wikidata are founded on a strict authority control that is built on a few cataloguing principles . in particular, both apply the principle that the authorized access point “for the name of an entity should be recorded as authority data along with identifiers for the entity and variant forms of name.”25 in addition, wikidata is a data provider in viaf, while viaf ids are constantly recorded and updated in wikidata items. at present, wikidata has 8,304,947 personal items, out of which 2,061,046 items have a viaf id. moreover, each month a wikidata bot (https://www.wikidata.org/wiki/user:krbot) updates links in wikidata items to redirected viaf clusters and removes links to abandoned viaf clusters. the relevance of viaf to the wikidata information ecosystem is evident in the visualization of external identifiers in the items: viaf ids, represented on wikidata by property p214 (https://www.wikidata.org/wiki/property:p214), are automatically sorted as the first external identifier, preceded by the group of iso standards and followed by the group of viaf sources.26 using specific gadgets, i.e., enhancements of the edit interface, wikidata registered users can add to a specific item the ids of single viaf sources extracting them from the viaf id(s) present in the item.27 unfortunately, there is no automatic reciprocity between viaf and wikidata: when a wikidata item gets a link to a viaf cluster, viaf does not have an automated way to add a reciprocal link to the wikidata item. likewise, when a viaf cluster gets a link to a wikidata item, wikidata has no automatic way to add a reciprocal link to the viaf cluster. another very important aspect of the viaf-wikidata relationship is that wikidata uploads data from viaf only by voluntary work of wikidata users; and this approach applies to national library data, and to any other data, too. when available, viaf ids are typically one of the most important elements used by users to decide the identity of a wikidata item. wikidata controls on viaf in wikidata, the use of constraints—i.e., rules that check the appropriate use of a property (https://www.wikidata.org/wiki/help:property_constraints_portal)—enables easy discovery of possible inconsistencies in statements, both in data and in external identifiers. weekly, a wikidata bot (https://www.wikidata.org/wiki/user:krbot2) updates the database reports containing the constraint violations for each property, so that users can check the issues and try to fix them. users can also check constraint violations in real time using the appropriate queries linked in the talk page of each property. as far as to viaf ids, two types of constraint-violations are particularly relevant both for the data entry and for the present paper: • “single value” violations, i.e., one item has two or more viaf ids. this means that either one or more viaf ids are not to be related to the item, so that the non-pertinent viaf ids should be removed from the wikidata item or that more viaf ids exist for the same real entity, so that all the existing viaf ids must be kept in the wikidata item until viaf merges them. an example of a merge performed by viaf, maybe on the basis of the correspondent wikidata item, can be found in iulius rufinianus (https://www.wikidata.org/wiki/q28131664), where the eight distinct viaf ids contained in the wikidata item on september 24, 2019, have now been merged (https://www.wikidata.org/w/index.php?title=q28131664&oldid=1001570078); in april 2021, the wikidata item for alaricus i (https://www.wikidata.org/wiki/q102371) contains https://www.wikidata.org/wiki/user:krbot https://www.wikidata.org/wiki/property:p214 https://www.wikidata.org/wiki/help:property_constraints_portal https://www.wikidata.org/wiki/user:krbot2 https://www.wikidata.org/wiki/q28131664

pellizzari di san girolamo 7 four viaf ids (but there were ten on june 29, 2020; https://www.wikidata.org/w/index.php?title=q102371&oldid=1220309663). • “unique value” violations, i.e., two or more wikidata items have the same viaf id. this violation means not only an error on the wikidata side, but it could imply an error in viaf too. in the former, either one or more wikidata items have a non-pertinent viaf id, to be removed; or the same entity is referred to by one or more wikidata items, to be merged. in the latter, the viaf id conflates two or more distinct entities in one cluster. an example of conflation is the cluster at https://viaf.org/viaf/57898554/, where the painter herbert e. abrams (1920–2003; https://www.wikidata.org/wiki/q4117019) and the physician herbert l. abrams (1920–2016; https://www.wikidata.org/wiki/q23665535) conflate. in that case, wikidata users can report the viaf conflation error in the proper wikidata errorreport pages.28 in most cases just a few weeks are required for viaf to merge clusters regarding the same entity when wikidata includes them in the same item, but solutions to cases of conflation are fixed more slowly. while updates to viaf clusters and ids are obviously necessary and welcome, they are somehow risky for viaf contributors, providers, and users that base the consistency of their data on viaf. so, national libraries could import incorrect data into their ids and wikidata could import wrong national libraries ids referring to different entities into the same wikidata item. there is no evidence that the error-report pages created and updated by wikidata users are being systematically taken into consideration by viaf to solve its conflations. recently, other issues in the use of viaf as a source were raised when viaf removed very important information about its cluster merging process, information that is no longer available to worldwide libraries and users. the viaf data dump page (http://viaf.org/viaf/data) is refreshed monthly and, until april 2020, it included a persist file. for example, the february 2020 dump, viaf-20200203-persist-rdf.xml.gz, contained data about redirected clusters and—potentially— abandoned clusters as well. this information is essential to the prompt and safe synchronization of local data with viaf clusters. in this dump, redirected clusters were described, for instance, as follows: <?xml version="1.0"?> <rdf:rdf xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:p="http://viaf.org/viaf/abandonedviafrecord"> <rdf:description rdf:about="http://viaf.org/viaf/100035417"> <owl:sameas rdf:resource="http://viaf.org/viaf/67529853"/> </rdf:description> </rdf:rdf> while any abandoned cluster (14,692,237 out of 24,030,176!) was erroneously described as follows: <?xml version="1.0"?> <rdf:rdf xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:p="http://viaf.org/viaf/abandonedviafrecord"/> this xml empty statement omits the specific information about the abandoned cluster. to obtain this invaluable information again, we filed a bug by email. 29 the decision taken was drastic: starting in may 2020, viaf stopped including this information in its monthly dump, as stated at the bottom of the page itself.30 as a result, the only recourse available to viaf contributors or any https://www.wikidata.org/w/index.php?title=q102371&oldid=1220309663 https://viaf.org/viaf/57898554/ https://www.wikidata.org/wiki/q4117019

that would synchronize their authority records with viaf identifiers is to rely on an external identification tool such as wikidata! materials and methods any comparison between viaf and wikidata must consider their different content. viaf contains personal name clusters, corporate name clusters, geographic name clusters, and work clusters, whereas wikidata allows items to describe any kind of entity relevant in the universe of discourse of the users’ data and irrespective of their bibliographic nature. even if all kinds of viaf clusters are relevant for bibliographic control, this study is limited to the analysis of personal name clusters in viaf and of items having “instance of: human” (p31:q5) in wikidata, because they are largely the most represented in viaf and they can be directly compared.31 some entities, such as mythological persons, legendary persons, etc., that are personal clusters in viaf, are not treated as humans in wikidata and belong to other instances (e.g., https://www.wikidata.org/wiki/q95074). a double approach was used to compare viaf and wikidata: first, data analyses of viaf and wikidata were performed, to compare viaf clusters and wikidata items and to investigate their reciprocal relationships (see the data analysis section). second, a comparison of several general characteristics, such as scope, objectives, philosophy, authority control, and identification, was made based on respective websites and available literature to find and highlight differences and similarities. full viaf dumps are available in native xml, rdf, marc-21 xml, or iso-2709 marc-21 (http://viaf.org/viaf/data/). viaf clusters were analyzed using an xml dump published on september 6, 2020 (http://viaf.org/viaf/data/viaf-20200906-clusters.xml.gz). full wikidata dumps are available in xml, json, or rdf.32 however, given the size of the entire dataset, it is much more convenient to create customized rdf dumps using the tool wdumper (https://wdumps.toolforge.org/). all the information (settings, dimension, and date of base dump) about dumps created using wdumper remains traced (https://wdumps.toolforge.org/dumps). wikidata items were analyzed using a customized rdf dump updated to september 14, 2020 (https://wdumps.toolforge.org/dump/732). the customized dump contains all statements with non-deprecated values33 present in items having both “instance of: human” (p31:q5) in best rank and at least one value of “viaf id” (p214) in best rank. both dumps were parsed using three perl scripts. dumps and scripts were uploaded on zenodo and are all available for analysis and reuse.34 perl scripts generate json data that are published on the html page http://catalogo.pusc.it/beyond_viaf/, where they are interpreted by javascript scripts in order to populate eight tables: three dedicated to viaf (tables 1–3) and five to wikidata (tables 4–8). in order to select the statements to be analyzed in wikidata items, three sets of relevant properties were found through three distinct sparql queries at the end of september 2020: viaf members (table 5), authority controls related to libraries but not being viaf members (table 6), and biographical dictionaries (table 7).35 at the beginning of october 2020, another sparql query was performed to find all the personal items containing the authority controls related to libraries but not being viaf members (table 6, column 4), without filtering the search to personal items having at least one value of “viaf id” (p214).36 https://www.wikidata.org/wiki/q95074

http://catalogo.pusc.it/beyond_viaf/, is a full, commented, and dynamic version of all the tables. within that version, links to the acronyms (such as lc, dnb, sudoc, etc.) of all the viaf contributors and other data providers are available too. static versions of these tables are included in this paper with commentary. viaf viaf has 22,099,715 personal clusters, half of which (50.90%; table 1, col. 2) are isolated clusters (i.e., they contain only one id). the presence of isolated clusters is interesting because it means that those clusters are created based on data coming from just one source. what is more, the percentage of isolated clusters is much higher (71.19%; table 1, col. 12) if just viaf contributors are taken into account (i.e., excluding isolated clusters due to data from other data providers, such as isni). it is worth noting that other data providers can form isolated clusters, with the relevant exception of wikidata (for which viaf uses the acronym wkp), which never appears in isolated clusters (table 1, cols. 7 and 8). table 1. viaf personal clusters by number of sources [adapted from http://catalogo.pusc.it/beyond_viaf/#tb1] the total number of ids present in viaf clusters is 51,327,847 (table 2), distributed in 22,099,715 clusters; the most relevant contributors include lc (7,266,628 ids), dnb (5,677,731 ids), sudoc (3,278,189 ids), and nta (2,754,036 ids), while the most relevant other data providers are isni (8,455,814 ids) and wkp (2,148,680 ids) (table 2). apart from lc and dnb, data about isolated clusters (table 2, col. 5) shows that the number of isolate clusters tends to slowly decrease over time and that clustering has improved: recently-added sources tend to have a higher share of isolated ids. another relevant figure is that sources in non-latin alphabets usually have higher shares of isolated ids.37 so, a high number of isolated clusters may reveal a source that is partially in need to be gathered to existing clusters. http://catalogo.pusc.it/beyond_viaf/ http://catalogo.pusc.it/beyond_viaf/#tb1 http://catalogo.pusc.it/beyond_viaf/#tb1 http://catalogo.pusc.it/beyond_viaf/#tb1

june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 10 table 2. viaf personal clusters by source [adapted from http://catalogo.pusc.it/beyond_viaf/#tb2] the histories of viaf clusters, as contained in xml dumps, appear weird and incoherent. for example, many viaf contributors in their first year of appearance seem to have no additions and many removals (e.g., bav row; for complete information see table 3 on the website at http://catalogo.pusc.it/beyond_viaf/#tb3). incoherence is due to the absence of redirected and abandoned clusters in the data. nevertheless, the histories allow us to reconstruct the year of first contribution of each source—an information otherwise unavailable—and to detect major changes in the data provided to viaf by each source.38 table 3. viaf history of personal clusters by source [adapted from http://catalogo.pusc.it/beyond_viaf/#tb3] wikidata wikidata has 8,304,947 personal items and 2,061,046 of them contain a viaf id. usually one or more viaf sources are extracted from the viaf id(s), so that 1,905,470 personal items containing viaf id have at least one viaf source id (table 4, col. 1). wikidata records ids from a wide range http://catalogo.pusc.it/beyond_viaf/#tb2 http://catalogo.pusc.it/beyond_viaf/#tb3 http://catalogo.pusc.it/beyond_viaf/#tb4 information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 11 of other resources, such as non-viaf bibliographic agencies and biographical dictionaries (investigated in these tables), but also encyclopedias and various online databases. considering the 2,061,046 items containing a viaf id, 684,367 items contain only one viaf source id (table 4, col. 1), but only 353,710 items contain only one among viaf sources ids and non-viaf sources ids and biographical dictionaries ids (table 4, col. 15); so, more than 300,000 items containing only one viaf source id have at least one non-viaf source id and/or one biographical dictionary id. table 4. wikidata personal items (pers. it.) by number of ids [adapted from http://catalogo.pusc.it/beyond_viaf/#tb4] viaf and wikidata: a data comparison from a quantitative perspective, wikidata personal items (8,304,947) are 37.58% of viaf personal clusters (22,099,715), while wikidata personal items having a viaf id (2,061,046) are 9.26%. ids from viaf sources present in wikidata personal items containing viaf id (6,292,778; table 5, col. 3) are 12.91% of ids present in viaf personal clusters (48,740,933; table 5, col. 4). in the authors’ opinion, quantitative confrontation between viaf and wikidata must be carefully considered. it could be argued that is a noticeable disadvantage of wikidata with respect to viaf, but it would be right only from a bibliographic control perspective and the other side of the coin must be examined too. as wikidata represents any kind of entity relevant for its users (libraries, archives, museums, and many other stakeholders), viaf contains just over a third of wikidata items (37%). furthermore, a very large part of the personal entities represented in wikidata (at present, more than 6,200,000, i.e., about 75%) cannot rely on viaf for identification purposes (for example, because wikidata personal items can also represent singers, lawyers, pilots, and so on). it can be concluded that viaf can be considered just one specialized source, in the domain of the semantic web and with respect to the objectives of wikidata. considering single viaf sources, wikidata surpasses viaf by number of ids only in two cases, perseus (135.18%) and simacob (102.17%) (table 5, col. 5). this is possible because wikidata and viaf gather different sets of data from both the sources; the former uses sets of data obtained by its users, while the latter uses only data sent by the contributor. all the other sources, because of the absence of systematic imports, are much rarer in wikidata than in viaf.

it.) by viaf source [adapted from http://catalogo.pusc.it/beyond_viaf/#tb5] table 6 and table 7 show authority control in wikidata living aside viaf. wikidata contains some non-viaf sources (usually non-national libraries or groups of libraries which couldn’t become viaf contributors); their ids in personal items having viaf id (894,161) are the 86.04% of their ids in all personal items (958,206; table 6, col. 4), meaning that wikidata provides a clusterization for more than 64,000 ids (6%) probably corresponding to non-existent viaf clusters (table 6, totals).

table 7. wikidata personal items (pers. it.) by biographical dictionary [adapted from http://catalogo.pusc.it/beyond_viaf/#tb7] in general the presence of ids of biographical dictionaries (796,609 ids in total) in 725,755 personal items having viaf id helps significantly in the definition of authoritative dates of birth and death (table 7, total of column 2 and table 4, total of column 12). http://catalogo.pusc.it/beyond_viaf/#tb7 http://catalogo.pusc.it/beyond_viaf/#tb4 information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 14 a comparison between table 1, column 7, and table 2, row wkp (the acronym for wikidata wrongly used by viaf) shows that 2,147,319 clusters contain 2,148,680 wkp ids; it means that, from a viaf point of view, wikidata duplicates are only 1,361. furthermore, a comparison between the total and row 0 in table 8, col. 1, shows that 2,061,046 items contain at least one viaf id and that 2,037,638 items contain exactly one viaf id; so, items containing one or more viaf duplicates are 23,408. as a result, it can be concluded that the percentage of duplicates in wikidata is less than 0.01% and in viaf is about 0.01%, so wikidata is as trustworthy as viaf. viaf and wikidata not only are able to discover reciprocal duplicates, but also discover duplicates in viaf sources, by a comparison between table 8, col. 3—containing the total number of the cases in which a viaf source has at least one duplicate—and table 8, col. 5—containing the total number of the cases in which viaf sources are duplicated. however, while duplicates recorded by viaf are findable only by querying the monthly dumps using in-house–made programs, duplicates discovered by wikidata are easily findable through sparql queries detecting single-value constraint violations. table 8. wikidata personal items (pers. it.) by repeated viaf sources and viaf source ids [adapted from http://catalogo.pusc.it/beyond_viaf/#tb8] discussion viaf and wikidata are quite different in their purpose, scope, organizational and theoretical approach, data harvesting and management. a major difference between viaf and wikidata is in their purpose: on the one hand, viaf aims to identify bibliographic entities and to connect authority data provided by selected contributors (national libraries, cultural agencies, and other major institutions) and extracted from other data providers (such as isni, rism or de663, wikidata, etc.) through the creation of clusters by means of software. on the other hand, like isni, wikidata focuses on both identification and description of entities and has the purpose of building collaboratively a database concerning the sum of all relevant knowledge—provided that each item complying with its notability criteria is accepted— using a crowdsourced approach (https://www.wikidata.org/wiki/wikidata:notability). http://catalogo.pusc.it/beyond_viaf/#tb1 http://catalogo.pusc.it/beyond_viaf/#tb2 http://catalogo.pusc.it/beyond_viaf/#tb8 http://catalogo.pusc.it/beyond_viaf/#tb8 http://catalogo.pusc.it/beyond_viaf/#tb8 http://catalogo.pusc.it/beyond_viaf/#tb8 https://www.wikidata.org/wiki/wikidata:notability information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 15 another relevant difference between viaf and wikidata is their scope: while viaf aims to identify a few selected types of entities already described within the bibliographic universe by national agencies, wikidata aims to identify and describe any kind of entity of interest for the wikidata community. wikidata items may exist for any kind of entity and may contain a very broad range of data and of external identifiers. so, wikidata can represent bibliographic data and entities —e.g., at present wikidata records data for the 54% of all the bibliographic sources cited in wikipedia entries—any other kind of entity provided for in viaf (i.e., agents, works, expressions, and places), and any other entity defined by the frbr-ifla lrm model (e.g., manifestations, items, timespans, nomens, res, etc.), and by other models relevant for the glam universe (such as frbroo and cidoc).39 but it is open to any data model because it can also include any kind of entity outside the bibliographic or cultural heritage universe, as it is a knowledge base capable of containing any kind of statement on any entity users want to describe. in addition, for any kind of entity there is no minimum or maximum number of statements that must or can be added; as soon as an entity is clearly identified, it can be added to wikidata. moreover, when miss ing, new identifiers—and properties for description—can be proposed by anyone through property proposals and, if well defined, they are usually approved within two weeks (https://www.wikidata.org/wiki/wikidata:property_proposal). a broader scope is supposed to be much more convenient for users who wish to discover previously unknown links and information in the semantic web. organizational model due to the viaf top-down approach, data is completely managed by oclc with no chance for common users or medium and small libraries or other institutions to directly improve viaf clusters (e.g., by adding other data coming from their collections or from encyclopedias or online databases, merging duplicates, solving conflations, etc.). as the wikidata approach is “to crowdsource data acquisition, allowing a global community to edit the data,” data is curated directly by users interested in their creation and use.40 so, in wikidata, data is produced by volunteers, by means of semiautomatic or manual data harvesting from any desired and available source. moreover, users’ statistics show that authoritative data from national bibliographic agencies and other libraries, archives, and museums are normally uploaded by common users, not by librarians (or any other kind of institutional data curator).41 identification function the theoretical approach differs too, both as to the form of the names and as to identification function. in viaf, preferred and variant forms of names for persons are based on national cataloguing codes. because national codes are different, viaf is needed and works as a neutral hub of all the national preferred forms. cataloguing rules can assure uniformity and univocity to the forms of the names of the entities within a national catalogue but are quite complicated to be understood and used by users. in ranganathan’s words, “the cataloguing conventions are on the surface quite contrary to what mr. everybody is familiar with.”42 in contrast, preferred forms in wikidata are based on the international principles of the convenience of the user and common usage.43 a clear example is the use of the direct form of name (jane doe) instead of the inverted form of name (doe, jane). a different usage in the forms of names could be an issue for the integration of library metadata in wikidata. in practice, however, it is not. first, there is no conflict between the wikidata form and any other form from a theoretical point of view, as wikidata form is already treated in viaf as the preferred form within its specific context.44 in addition to that, wikidata accepts any library https://www.wikidata.org/wiki/wikidata:property_proposal information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 16 identifier, so that any library-controlled form can be linked to a wikidata item and vice versa. furthermore, a wikidata bot could be programmed to dump authorized and variant access points from national authority files and add them to the item labels and aliases. 45 lastly, it could be argued that national cataloguing codes are compliant with the icp principles and with the convenience of the user and common usage. but a remarkable difference is that while in national codes principles are applied by cataloguers for users, in wikidata they are expressed directly by the users themselves. as the identification function is a major feature of the semantic web, the different approach of viaf and wikidata to this issue must be underlined. as noted, “viaf remains neutral towards differences in the cataloguing policy of its data contributors” and, for this reason, viaf accepts all ids provided by its sources, even when they are not clearly identifiable entities but are just labels (see for example https://viaf.org/viaf/307171748 or https://viaf.org/viaf/305052259).46 on the contrary, wikidata explicitly requires each item to refer to “a clearly identifiable conceptual or material entity” (second notability criterium; https://www.wikidata.org/wiki/wikidata:notability). as a consequence, many isolated clusters formed by viaf on the basis of single contributors’ ids related to not-clearly-identifiable entities are not acceptable in wikidata and remain unlinked. moreover, data on cluster duplication shows that identification in wikidata is performed with the same quality level as in viaf. clusters for identification purpose are created both in viaf and wikidata, but differently from viaf, in wikidata external identifiers—as all the other data—are not provided in a structured way by national libraries or other institutions (with very few exceptions); instead, identifiers are usually found and added by common users through web scrapers and after data cleaning. what is more, matches are not performed automatically, but semiautomatically (through tools such as openrefine or mix’n’match (https://mix-n-match.toolforge.org/ and https://openrefine.org/) or manually. an enhanced feature of wikidata in clusterization is the record of a wider variety of sources and relative ids: due to its openness, wikidata refers to viaf and its sources, but also to any other library or cultural institution and to a large number of reference sources like encyclopedias and biographical dictionaries too (table 7). a wider variety of identification sources and manual work assure a higher level of identification. data quantity data harvesting affects both quantity and quality of data. in viaf, data are collected from periodical contributions of viaf participants, with very large sets of data. therefore, from a quantitative point of view, viaf has a far larger number of people (22,099,715 personal clusters) in comparison with wikidata (8,304,947 personal items). even though wikidata was created in 2012, the number of personal items in wikidata is currently only over a third (37%) of all viaf personal clusters. although quantities are not directly comparable due to the different universe to be described, in the last few years initiatives to enhance organized cooperation between libraries and wikidata and to promote data production in wikidata are increasing. a very high-quality initiative is supported by cornell university, harvard university, stanford university, and the university of iowa’s school of library and information science, in collaboration with the library of congress and the program for cooperative cataloging (pcc). their linked data for production (ld4p) wikidata project is “an indepth exploration of how wikidata could serve as a platform for publishing, linking, and enriching library linked data” https://viaf.org/viaf/307171748 https://viaf.org/viaf/305052259/#jones,_a._l https://www.wikidata.org/wiki/wikidata:notability https://mix-n-match.toolforge.org/ https://openrefine.org/ http://catalogo.pusc.it/beyond_viaf/#tb7 information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 17 (https://www.wikidata.org/wiki/wikidata:wikiproject_linked_data_for_production). an additional example is the ifla wikidata working group that was formed “to explore and advocate for the use of and contribution to wikidata by library and information professionals, the integration of wikidata and wikibase with library systems, and alignment of the wikidata ontology with library metadata formats such as bibframe, rda, and marc” (https://www.ifla.org/node/92837). even so, wikidata is still very far from having a structured workflow to ingest data from national or local libraries, museums, and archives. in fact, while the projects mentioned above are mainly dedicated to explaining to the public of librarians and institutions why wikidata is important and how to contribute to it, there are still very few projects which are mainly dedicated to the concrete massive synchronisation of data between library and bibliographic data and wikidata. in fact, they also require a relevant effort in the manual cleaning of discrepancies and oddities emerging from the synchronisation. relevant exceptions are the national library of wales 47 and the biblioteca europea di informazione e cultura, where significant work has been done to synchronise respective databases of authors (and of other types of entities) with wikidata. 48 data quality data quality also needs to be analyzed in detail. even if data from national libraries are authoritative and of high quality, as a virtual file viaf neither has nor produces its own data. consequently, viaf data does not always remain authoritative because errors can be both inherited and added, and clusters can be duplicated. the issue is well known by isni, that “whenever necessary [. . .] splits and merges data coming from viaf, and even applies protection to data that has been fixed manually.”49 as shown in table 2 and table 8, viaf clusters are subject to isolation and duplication when they are created and to many changes and updates when they are maintained. so, even if viaf collects a huge amount of authoritative data and creates clusters of ids, viaf users can not always safely and continuously rely on them. data flows just in one direction (from national libraries to viaf), viaf deletes and rebuilds clusters without giving priority to the stability of one cluster over another, and, after april 2020, viaf no longer makes available to users a record of its changes.50 on the contrary, wikidata data is always under strict control of any user, as its structure is designed to trace any minimum change to its data. every single addition or deletion is documented, not just to easily recover eventual vandalism, but also to support any decision with clear evidence. any stakeholder can exactly know if, how, when, and why data changed, in any moment. what is more, from a qualitative point of view, wikidata seems to offer a better solution for the recording of authority data than viaf. first, it can store a wider variety of data about a person in a more semantic way. not only is it possible in wikidata to express preferred and variant forms of the name, related names, works, co-authors, publication statistics, and other data about the person—like in viaf—but all these data are all expressed in a semantic way. for example, whereas in viaf “bach, anna magdalena” is just a related name of johann sebastian bach, in wikidata she is recorded and qualified as the person who married the musician. thanks to that different approach, wikidata can represent and show bach’s full genealogic tree (https://magnustoolserver.toolforge.org/ts2/geneawiki/?q=q1339). as adamich noted, “building graphs from bibliographic entities is really about making the data machine readable and understandable. it is about making the data web enabled. in terms of translation, linked data opens up a whole new world over our marc entrapment.”51 https://www.wikidata.org/wiki/wikidata:wikiproject_linked_data_for_production https://www.ifla.org/node/92837 http://catalogo.pusc.it/beyond_viaf/#tb2 http://catalogo.pusc.it/beyond_viaf/#tb8 https://magnus-toolserver.toolforge.org/ts2/geneawiki/?q=q1339 https://magnus-toolserver.toolforge.org/ts2/geneawiki/?q=q1339 information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 18 quality is enhanced by matching methods too; whereas viaf matches identities by an algorithm based on explicit identifiers or string matching (such as the forms of the name, dates, and bibliographic relationships),52 wikidata matches are usually decided by a human, the user, or (in the case of semiautomatic imports) at least checked a posteriori by a human after some time. the higher precision of manual over automatic matching is recognized also in viaf guidelines. 53 furthermore, as seen above, notability requires that, when clear identification is impossible, no item must be created in wikidata. data maintenance and usability data quality relies also on maintenance. comparison between wikidata items and viaf clusters shows a very small but constant presence of errors to be fixed in both (around 0.01%), even if it is impossible to determine with certainty whether viaf uses wikidata error pages. issues on fixing viaf errors directly by viaf contributors were already noted: “while clustering anomalies can be handled by viaf itself, reporting errors found in source data of viaf partners raise problems related to the efficiency of the notification workflows. at this point, involvement of viaf partners themselves in the process is needed.”54 on the other hand, in wikidata anyone can edit items, add new data or delete mistakes, merge items, fix various issues, and so on, on the fly. due to its openness, wikidata may also suffer from vandalism, but it has its own solutions.55 along with this, data receive special attention to their accuracy and reliability because they are uploaded and maintained by users that are direct stakeholders. for this reason, in wikidata, references to bibliographical or biographical sources and to other data provider ids such as any national and international identification system are suggested, promoted, and carefully examined. moreover, there is a commitment to monitor the consistency of viaf clusters. the ability of wikidata to identify inconsistent viaf clusters and the fact that viaf isolated clusters can be reduced at least by 30%56 by referring to identifiers from wikidata and other data providers, are the best demonstration of the quality of its data and of the importance of the other data providers in viaf clusterization. as to the usability of data, the internal search of viaf lacks more than basic functions: the only available filter allows to limit results to clusters having one specific source; on the contrary, filtering searches for clusters having and/or not having a specific group of sources or to clusters having more or less sources would be very useful, especially in order to find duplicates. in contrast, wikidata has a sparql query service which returns results based on the current status of the database and its internal search can integrate some of the functions of the query service, allowing to look for items having and/or not having specific statements (https://www.wikidata.org/wiki/special:search).57 considering cases in which viaf and wikidata discover potential duplicates in their sources, viaf has no page dedicated to listing cases of (supposedly) duplicate ids from its sources, while wikidata easily allows to find cases in which single sources have (supposedly) duplicate ids through constraint violations58 and appropriate sparql queries. a comparison table a comparison table was built to compare scope, role, system, and functions between viaf and wikidata, inspired by and adapted from a viaf vs isni comparison.59

and wikidata features and personal entities data were analyzed and compared in this study to focus on analogies and differences, and to highlight their reciprocal role and helpfulness in the worldwide bibliographical context and in the semantic web environment. viaf is a major international initiative to address the challenge of reliably identifying bibliographic agents on the web, by means of authoritative data based on national cataloguing codes and coming from the national libraries involved in the ubc program. moreover, viaf is a pillar of the identification process that users enact within wikidata. still, the comparison emphasized a few relevant issues in viaf’s approach, designed more than twenty years ago: a very selective policy of inclusion of its sources—contributors and other data providers—and to their participation to the governance, that prevents a worldwide openness of the project to non national libraries and cultural institutions; an obvious neutrality toward data coming from its https://www.wikidata.org/wiki/help:about_data https://www.wikidata.org/wiki/help:about_data https://www.wikidata.org/wiki/help:about_data https://www.wikidata.org/wiki/help:about_data information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 23 contributors, even when data are not compliant with the identification requirements of the semantic web; troubles in correct clustering of ids (duplicate clusters to be merged and conflated clusters to be split), and a one-way flow of data due to its top-down approach that prevents a quick and cooperative workflow to identify and fix errors; the ability to identify only a narrow range of entities (i.e., mainly bibliographic entities, but not even all those provided by ifla lrm). on the other side, the semantic web has offered new important tools and chances to libraries, archives, museums and other cultural institutions, and their data are recognized as a relevant asset for building the backbone of the semantic web as to the control of entities of bibliographic and cultural interest. after eight years of existence, wikidata is playing a relevant role in the publication, aggregation, and control of bibliographic and non-bibliographic information in the semantic web too. it is more and more indicated as a hub for identifiers in the semantic web.83 wikidata depends on viaf for a large part of the identification work of its items on viaf and viaf’s preeminent role in wikidata is acknowledged by its primary position in the identifiers section of the data of each item. for this reason, the wikidata community constantly monitors the consistency of viaf clusters and continuously updates lists of errors present in them . on the other hand, if viaf is undoubtedly very useful to the wikidata community, wikidata can support the consistency of viaf clusters. the wikidata informational ecosystem is much larger and wider, can be built by any interested institution and person, and its identification function can count also on the authority work of national and non-national libraries excluded from the viaf environment, and on authoritative non-bibliographical reference sources too. this study opens some research perspectives. analysis was limited to data about personal entities, as this kind of entity was the only one directly comparable, while further research is wanted to possibly extend the analysis to other kinds of entities. moreover, more research should be devoted to the investigation of the treatment of special categories of persons and their names, such as mythological and legendary characters, ancient greek and latin authors, kings, queens, popes, saints, and so on, as viaf guidelines84 themselves declare among viaf’s typical problems the clusterization of such names (and they often get five or more viaf ids in wikidata). a further line of research should consider the relevance of the clusterization of encyclopedias and other reference sources in the identification process within wikidata. lastly, isolated clusters would need more consideration; as a matter of fact, in this study they were used as a clue of relatively recent uploads in viaf, but lc and dnb show a high rate of isolated clusters too (maybe due to the richness of their collections and metadata). more research on isolated clusters could help to describe with more precision the possible role of non-national libraries and institutions and of their locally rich collections in identifying lesser-known agents (not just persons) in a worldwide perspective. from analyzed data and direct comparison, it can be concluded that viaf and wikidata can be constantly improved through reciprocal comparison, which allows discovery of errors in both. viaf and wikidata are two relevant tools for the authority control in the semantic web and they each have a specific role to play and different stakeholders. unfortunately, as opposed to the relationship between viaf and isni, at present no aspect of viaf-wikidata interoperability is discussed between the managing structures of both systems, on a regular or irregular basis . while wikidata appears to be more reliable with regards to the identification process, its most significant weakness consists in its unorganized and unplanned crowdsourced data acquisition, information technology and libraries june 2021 beyond viaf | bianchini, bargioni, and pellizzari di san girolamo 24 even if based at present on about 11,500 active editors.85 furthermore, the wikidata community still lacks the constant support and cooperation of institutional data curators such as librarians, archivists, and museum curators. many current projects are mainly dedicated to explaining to the potential institutional stakeholders the importance and the usefulness of wikidata for their institutional missions, but there are still too few projects devoted to massive synchronization of data from institutional silos to wikidata. but, as soon as these initiatives reach a critical mass, wikidata will become the real global hub of the web of data. acknowledgements all the authors have cooperated in the redaction and revision of the article. nevertheless, each author has mainly authored specific sections and subsections of the article:

president’s message updates from the 2019 ala midwinter meeting bohyun kim information technology and libraries | march 2019 2 bohyun kim (bohyun.kim.ois@gmail.com) is lita president 2018-19 and chief technology officer & associate professor, university of rhode island libraries, kingston, rhode island. in this president’s message, i would like to provide some updates from the 2019 ala midwinter meeting held in seattle, washington. first, as many of you know, the potential merger of lita with alcts and llama has been temporarily put on hold, due to an initial timeline that was rather ambitious and the lack of time required to deliberate on and resolve some issues in the transition plan to meet that timeline.1 these updates were also shared at the lita town hall during the midwinter meeting, where many lita members spent time discussing topics such as the draft mission and vision statements for the new division, what makes people feel at home in a division, in which areas lita should redouble its focus, and which activities lita may be able to set aside without losing its identity. valuable feedback and thoughts were provided by town hall participants. many emphasized the importance of building and retaining a community of library technologists around lita values, programming, resources, advocacy, service activities, and networking opportunities in those feedback. the merger-related discussion is to resume this spring, and the leadership of lita, alcts, and llama will make every effort to ensure the best future for three divisions at this time of great flux and change. second, lita is looking into introducing some changes to the lita forum. in the feedback and thoughts gathered at the lita town hall, the lita forum was also mentioned as one of the valuable lita offerings to its members. the origin of the lita forum goes back to lita’s first national conference held in baltimore in 1983.2 since then, the lita forum has become a cherished venue for many library technologists, a place where they meet other like-minded people in the field, learn from one another, share ideas and experience, and look for more ways in which technology can be utilized to better serve libraries and library patrons. initially, the steering committee hoped that all three divisions would participate in putting together the lita forum with a wider range of content that encompasses the interests of not only lita members but also of those in alcts and llama, in a virtual format in order to engage more members who cannot easily travel, to be held some time in spring 2020. at the time this idea was conceived more than a year ago, it was assumed that all preparations for the member vote regarding the merger would have been nearly completed by the time of the midwinter meeting. however, the steering committee unfortunately ran out of time for that preparation. merger planning also took up almost the entirety of the time that the leadership and the staff of the three divisions had available. this resulted in an unfortunate delay in proper forum planning. with the merger conversation on hold at this point and the new timeline for the merger being likely to be set back at least by a year, the changed circumstances for the forum planning had to be reviewed. information technology and libraries | march 2019 3 after a lively and thoughtful discussion at the midwinter meeting, the lita board decided that, considering how much work remains to be done regarding merger planning, it may not be practical or feasible to have the next lita forum be the first virtual and joint one. however, there was a lot of interest in and excitement about trying a virtual format since it will allow lita to reach and serve the needs of more lita members than the traditional in-person meeting. it was also pointed out that the virtual format may provide an opportunity for lita to experiment with different and more unconventional conference program formats, which could be a welcoming change to lita members. the lita board, however, also acknowledged the value of a physical conference where people get to meet one another in person, which cannot be easily transferred to a virtual conference. if the virtual conference experiment takes place and is successful, lita may hold its forum alternating every year between two different formats – virtual and physical. planning for and running a fully virtual conference at the scale of a multi-day national forum will require additional time and careful consideration since it will be the first time the lita forum planning committee and the lita office attempt this. logistics management is likely to be quite different in a virtual conference. the attendee expectations and the user experience will also significantly differ in a virtual conference than in a physical conference. as the first step of this investigation, the lita forum planning committee will explore what the ideal lita virtual forum may look like in terms of programming formats and participant experience. the lita office and the finance advisory committee will also look into the financial side of running the lita forum in a virtual format. at this time, it is not yet determined when the next lita forum will be held and whether it will be a virtual or a physical one. once these investigations are completed, however, the lita board should be able to decide on the most appropriate path towards the next lita forum. stay tuned for what exciting changes may be coming to the lita forum. third, i would like to mention that lita issued a statement regarding the incidents of aggressive behavior, racism, and harassment reported at the 2019 ala midwinter meeting.3 along with the statement, the lita board has decided to commit funds to provide an online bystander / allyship training, which we hope will equip lita members with tools that empower active and effective allyship, recognize and undo oppressive behaviors and systems, and promote the practice of cultural humility, thereby collectively increasing our collaborative capacity. the lita statement and the board decision were received positively by many lita members. other ala divisions such as alcts, alsc, asgcla, llama, united, and yalsa have already expressed interest in working together with lita on this, and the lita board is looking into a few options to choose from. more information about the training will be soon provided. lastly, i am thrilled to announce that the lita president’s program at the upcoming ala annual conference at washington d.c in june will feature meredith broussard, a data journalist and the author of artificial unintelligence: how computers misunderstand the world, as the speaker. in her book, broussard delves into many problems surrounding techno-chauvinism, which displays blind optimism about technology and an abundant lack of caution about how new technologies will be used. she further details how this simplistic worldview that prioritizes building new things and efficient code above social conventions and human interactions often misinterprets a complex social issue as a technical problem and results in a reckless disregard for public safety and the public good. lita president’s message: updates from the 2019 ala midwinter meeting | kim 4 https://doi.org/10.6017/ital.v38i1.10980 reviewing the early history of computing and digital technology, broussard observes: “we have a small, elite group of men who tend to overestimate their mathematical abilities, who have systematically excluded women and people of color in favor of machines for centuries, who tend to want to make science fiction real, who have little regard for social convention, who don’t believe that social norms or rules apply to them, who have unused piles of government money sitting around, and who have adopted the ideological rhetoric of far-right libertarian anarcho-capitalists. what could possibly go wrong?”4 i invite all of you to come to this program for more insight and a deeper understanding about what the recent technology innovation involving artificial intelligence (ai) and big data means to our everyday life and where it may be headed. the program information is available in the ala 2019 annual conference scheduler at

massachusetts: the mit press, 2018), p. 85. in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs manolis peponakis abstract the aim of this study is to contribute to the field of machine-processable bibliographic data that is suitable for the semantic web. we examine the entity relationship (er) model, which has been selected by ifla as a “conceptual framework” in order to model the fr family (frbr, frad, and rda), and the problems er causes as we move towards the semantic web. subsequently, while maintaining the semantics of the aforementioned standards but rejecting the er as a conceptual framework for bibliographic data, this paper builds on the rdf (resource description framework) potential and documents how both the rdf and linked data’s rationale can affect the way we model bibliographic data. in this way, a new approach to bibliographic data emerges where the distinction between description and authorities is obsolete. instead, the integration of the authorities with descriptive information becomes fundamental so that a network of correlations can be established between the entities and the names by which the entities are known. naming is a vital issue for human cultures because names are not random sequences of characters or sounds that stand just as identifiers for the entities—they also have socio-cultural meanings and interpretations. thus, instead of describing indivisible resources, we could describe entities that appear in a variety of names on various resources. in this study, a method is proposed to connect the names with the entities they represent and, in this way, to document the provenance of these names by connecting specific resources with specific names. introduction the basic aim of this study is to contribute to the field of machine-processable bibliographic data. as to what constitutes “machine processable” we concur with the clarification of antoniou and van harmelen, who state, “in the literature the term machine-understandable is used quite often. we believe it is the wrong word because it gives the wrong impression. it is not necessary for intelligent agents to understand information; it is sufficient for them to process information effectively, which sometimes causes people to think the machine really understands.”1 also, in the bibliography used, the term “computationally processable” is used as a synonym to “machine­ processable.” manolis peponakis (epepo@ekt.gr) is an information scientist at the national documentation centre, national hellenic research foundation, athens, greece. information technology and libraries | june 2016 19 mailto:epepo@ekt.gr with regard to machine-processable bibliographic data, we have taken into consideration both the practice and theory of library and information science (lis) and computer science. from lis we have chosen the functional requirements for bibliographic records (frbr) and the functional requirements for authority data (frad) while making comparisons with the resource description and access (rda) standard. from the computer science domain we have chosen the resource description framework (rdf) as a basic mechanism for the semantic web. we examine the entity relationship (er) model (selected from ifla as a “conceptual framework” for the development of frbr), 2 as well as the potential problems that may arise as we move towards the semantic web. having rejected the er model as a conceptual framework for bibliographic data, we have built on the potential of rdf and document how its rationale affects the modeling process. in the context of the semantic web and uniform resource identifiers (uris), the identification process has been transformed. for this reason we have performed an analysis of appellations and names as identifiers and also explored how we could move on from an era where controlled names play the role of identifiers to one of the uri dominion: “while it is self-evident that labels and comments are important for constructing and using ontologies by humans, the owl standard does not pay much attention to them. the standard focuses on the syntax, structure and reasoning capabilities. . . . if the semantic web is to be queried by humans, there will be no other way than dealing with the ambiguousness of human language.”3 it is essential to build on the “library's signature service, its catalog,”4 and use it to provide addedvalue services. but to get there, first there has to be “a shift in perspective, from locked-up databases of records to open data shared on the web.”5 this requires a transition from descriptions aimed at human readers to descriptions that put the emphasis on computational processes to escape the rationale of records being a condensed description in textual form and move towards more flexible and fruitful representations and visualizations. background frbr and rda the fr family has been growing for more than a decade. the first member of the family was the functional requirements for bibliographic records (frbr),6 the first version of which was published towards the end of the last century. subsequently, ifla decided to extend the model in order to cover authorities. during this process, the task of modeling the names was separated from the task of modeling the subjects. thus two new members were added to the family; the “functional requirements for authority data: a conceptual model” (frad) and the “functional requirements for subject authority data (frsad).” 7,8 at the same period of time, the “resource description and access” (rda) standard was established as a set of cataloging rules to replace the aacr standard. according to its creators, the alignment with the fr family was crucial. as stated, in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 20 “a key element in the design of rda is its alignment with the conceptual models for bibliographic and authority data developed by the international federation of library associations and institutions (ifla): functional requirements for bibliographic records [and] functional requirements for authority data.”9 this paper uses the fr family and the rda as a starting point but detects some problems and inconsistencies between these models. it sustains the basic semantics from these standards but rejects their structural formalism because it finds that it is quite problematic and lacks effectiveness in expressing highly machine-processable data. the effective processability of the data will be discussed in detail in the section “the impact of the representation scheme’s selection: rdf versus er.” among the fr family, the terminology is inconsistent and, as we pass from the frbr to frad and frsad, even the perception angle of the general model undergoes change. in frbr (the first in order), there is no notion of the name as an entity. frad introduces this perception (frad also adds family as a new entity) and frsad makes a step forward and introduces the concept of nomen instead of the concept of name. hence, despite the fact that each of the members of the fr family of models has been represented in rdf,10 there is no established consolidated edition yet that combines the different angles using a common model and terminology (vocabulary).11 these representations (one for each model) are available at ifla’s website.12 on the other hand, in the context of rda there may be more consistency regarding terminology, but, as is well established in the relevant literature, there are significant differences between the two models, i.e. the fr family and rda.13,14,15 due to these differences, there are no uris, not even in the rda registry, in the examples of our study.16 given the above, the terms appearing in the figures are a selection from the three texts of the fr family. thus, nomen (from frsad) is used instead of name (from frad) as a more abstract notion, and the attribute—property in the context of rdf—“has string” (from frad) is used to assign a specific literal to a nomen. in figures 2–5 we have used the “has appellation” (reversed “is appellation of”) relationship of frad.17 notes about terminology and graphs: how to read the figures in this paper two different sorts of figures appear. this covers the need to compare two different models and pinpoint the differences between them and the problems that arise from selecting the er model to express frbr. an explanation of the two major models follows in the next subsection. information technology and libraries | june

• the diamond-shaped boxes represent relationships. the second figure type has been created according to the rdf graphical representations and is used in figures 2–5. in these cases: • the oval shapes represent nodes that are identified by a uri and they could serve as objects or subjects for further expansion of the network. in figures 3–5 all the names were derived from the fr entities. • the line connectors between nodes represent the predicates (i.e., they are properties) and should also serve as uris. • the rectangle shapes represent literals consisting of lexical form. language code could apply in these cases. with or without language codes, these are the end points and they could not be subject to new connections. we follow the common modeling of the language in rdf in which the literal itself contains a language code, for example "example"@en in standard turtle syntax, or <rdfs:label xml:lang="en"> in rdfs xml coding. we must note that this kind of modeling is quite a simplistic way of language modeling because there is no mechanism to declare more information about language, such as multiple scripts, which could apply in the context of the same language. the impact of the representation scheme’s selection: rdf versus er nowadays, all the information on library catalogs is created through and stored in computers. this technological infrastructure provides specific methods and dictates limitations for the catalog’s data management. hence, every model must take into consideration the basic rationale of the technological infrastructure that will curate and process the data. depending on the syntax capabilities of the representation model, the expression of what we want to express becomes reasonably easy and accurate since “semantics is always going to have a close relationship with the field of syntax.”18 this establishes a vital relationship between what we want to do and how computers can do it. in this section we emphasize the limitations of the entity relationship (er) implementation, which frbr proposes, and denote how syntax affects expressiveness and, accordingly, functionality. finally, we demonstrate how the selection of one implementation or another (in our case er vs. rdf) has serious implications, both for cataloging rules and for cataloging practice. in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 22 why do we compare these two specific models? the er model is the base that has been selected from ifla as a “conceptual framework” 19 for the development of frbr, while frbr is the conceptual model upon which rda has been founded. subsequently, rda is also affected by the choice of er model. on the other hand, rdf is the current conceptualization for resource description in the web of data. so, what kind of problems and conflicts arise from the implementations of each of these models? the basic rationale of er comprises three fundamental elements. there are entities; entities have attributes; and there are relationships between entities. it is also possible to declare cardinality constraints upon which the fr family builds. then again, rdf implies quite a different model. “the core structure of the abstract syntax is a set of triples, each consisting of a subject, a predicate and an object. a set of such triples is called an rdf graph. an rdf graph can be visualized as a node and directed-arc diagram, in which each triple is represented as a node-arc-node link. . . . there can be three kinds of nodes in an rdf graph: iris, literals, and blank nodes.”20 “linking the object of one statement to the subject of another, via uris, results in a chain of linked statements, or linked data. this avoids the ambiguity of using natural language strings as headings to match statements. as a result, a literal object terminates a linked data chain, and literals are generally used for human-readable display data such as labels, notes, names, and so on.”21 as a representative example of the differences between the two models, let us consider “place of publication.” peponakis counts nine attributes of place and notices that, due to the fact that the er model does not allow links between attributes, there is no way to define explicitly whether these attributes address the same place or not.22 taking into consideration this problem we demonstrate the transition from the er attributes approach to rdf implementations in figures 1– 2. let us assume that there is person (x), who was born in london, is named john smith and works at publisher (y). this publisher is located in london, where book (1), entitled history of london, has been published. for this specific book, person x was the lithographer. if we create a strict mapping to frbr entities, attributes, and relations, then we have the situation illustrated in figure 1. due to the fact that there is no way to link the four occurrences of london (inasmuch as there is no option to define relations between attributes in the er model), there is no way to be certain that london is the same in all cases. judging only by the name, it could stand for london in england, in ontario, in ohio, or elsewhere. information technology and libraries | june 2016 23 figure 1. example of “place” as attribute of several entities the ifla working group has faced the problem with place and noted the following. the model does not, however, parallel entity relationships with attributes in all cases where such parallels could be drawn. for example, “place of publication/distribution” is defined as an attribute of the manifestation to reflect the statement appearing in the manifestation itself that indicates where it was published. inasmuch as the model also defines place as an entity it would have been possible to define an additional relationship linking the entity place either directly to the manifestation or indirectly through the entities person and corporate body which in turn are linked through the production relationship to the manifestation. to produce a fully developed data model further definition of that kind would be appropriate. but for the purposes of this study it was deemed unnecessary to have the conceptual model reflect all such possibilities. 23 finally, they seem to avoid the problem and repeat their position in frad as well. in certain instances, the model treats an association between one entity and another simply as an attribute of the first entity. for example, the association between a person and the place in which the person was born could be expressed logically by defining a relationship (“born in”) between person and place. however, for the purposes of this study, it was deemed sufficient to treat place of birth simply as an attribute of person. 24 in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 24 for some reason the creators of the fr family have chosen not to “upgrade” the attributes of place into one and only one entity. furthermore, the same problem exists for many attributes, not only for place. thus, the problem has to do with the selection of er as “conceptual framework” and not with the specific entity of place. if we accept that “place of publication” must not be recorded as it appears on the resource, an rdf-based approach makes things clearer, as figure 2 shows. in this case, all attributes of place are promoted to the same rdf node and, instead of four repeats of the attribute with the value “london,” we reduce it to one and only one node with four connections to it. then, as illustrated by figure 2, we can be sure that all instances refer to the same london. figure 2. rdf-based representations of figure 1 in figure 2, it is assumed that there is no need to transcribe the literal of “place of publication” from the resource; i.e., we did not follow rule 2.8.1.4 of rda: “transcribe places of publication and publishers' names as they appear on the source of information.” for cataloging rules that demand to record the place as it appears on the resource, the readers can consult the subsection “place names” in this study. last but not least, rdf has another significant advantage compared to the er model: data coded in rdf are packed ready for use in the semantic web. on the contrary, data coded in er must undergo conversion—with all its implications—in order to be published in the semantic web. information technology and libraries | june 2016 25 names, entities, and identities in this section, the significance of names as carriers of meaning is outlined and the importance of documenting the relations of names with the entities and identities they refer to is established. additionally, the basic approaches are presented for metadata generation for managing names. these approaches resulted in the distinction (dissociation of authorities) from the bibliographic records, which in turn led (both frbr/frad and rda) to the lack of potentially linking—in an explicit way—the entity with the names it goes by. this linking, as it is presented later in this text, is fundamental for the description and interpretation of the entity. in everyday communication, the usage of a name in a sentence plays the role of the identifier for the entity that this specific name indicates. if the speakers share a common background, there is no need for qualifiers other than the name in order to disambiguate information such as whether nick is person x or person y, or if the word “london” indicates the city in ohio or in england, etc. thus, the common background leads to a very limited context in which the interpretation of the name and the assignment to the appropriate entity is sufficient and accurate. however, the context of the internet is extended into a variety of possibilities, so there is need of a more precise way to identify specific entities. in this regard, a very essential issue is the distinction between the properties of the name and the properties of the entity that is represented by the specific name. the word “john” could be recognized as an english name, but we jump to a logical flaw if we assume that john knows english. a representative example of this kind of inference (syllogism) can be found in rayside and campbell.25 statement: “man is a species of animal. socrates is a man. therefore, socrates is a species of animal. . . . ‘man' is a three-lettered word. socrates is a man. therefore, socrates is a three-lettered word.” therefore the authorities of a catalog should embody a two-level modeling of the information they represent. the first has to do with the entities and the second with the names of these entities. consequently, there is the need to find a way to pass from names to the entities they indicate; and, from entities, to the various appellations that these entities have. in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 26 in catalogs, it is kind of vague whether the change of a name signifies a new identity. niu states: “for example: the maiden name and the married name of an agent are normally not considered two separate identities, yet one pseudonym used for writing fiction and another pseudonym used for writing scientific works are often considered two different identities of an agent.”26 then there can be one individual with many identities. but there can also be one identity which incorporates many individuals: for example, a shared pseudonym for a group of authors. to deal with these problems, frad introduces the notion of persona, rejecting at the same time the idea that a person is equal to an individual. frad defines a person as an “individual or a persona or identity established or adopted by an individual or group.”27 the question that arises here is when the persona must be conceived as a new identity. yet, frad does not make a sufficient judgment; instead, they refer to cataloguing rules. “under some cataloguing rules, for example, authors are uniformly viewed as real individuals, and consequently specific instances of the bibliographic entity person always correspond to individuals. under other cataloguing rules, however, authors may be viewed in certain circumstances as establishing more than one bibliographic identity, and in that case a specific instance of the bibliographic entity person may correspond to a persona adopted by an individual rather than to the individual per se.”28 so there is no specific guidance if, for example, in the case of “religious relationship,”29 there must be one identity created with two alternative names or two different identities. rule 9.2.2.8 in rda does not elaborate further. still, even with the problem of identities solved, the matter of appellations itself could be extremely complicated, and this is widely addressed in relevant literature.30,31,32 the viaf project confirms this with an extremely huge data set .33 assigning all appellations as attributes is an easy way to model the variants of a name, but it is very simplistic because it “does not allow these appellations to have attributes of their own and neither does it allow the establishing of relationships among the appellations. . . . frad makes a big step forward: all appellations are defined as entities in their own right, thus allowing full modeling.”34 of course, frad’s approach is not a novelty in the domain of lis since library catalogs have been modeling names since the era of marc. in unimarc authorities,35 the control subfield $5 contains a coded value to indicate the relations between the names with values such as “k = name before the marriage,” “i = name in religion,” “d = acronym,” etc., and in marc 21 there is the corresponding subfield $w.36 frad puts these values on a more consistent and abstract level. frad also defines “relationships between persons, families, corporate bodies, and works” in section 5.3 and “relationships between their various names” in section 5.4.37 the distinction between authorities and descriptive information since the days of card catalogs and for as long as marc and aacr have been used, bibliographic records have set their grounds on the dichotomy between descriptive information and control access points. the various types of headings stand for control access points. the terminus of headings was the alphabetical sorting. with the advent of computers, they were used as string identifiers to cluster and retrieve relevant bibliographic records. these bibliographic records had information technology and libraries | june 2016 27 a body of descriptive information that was transcribed from the resource and remained unchanged. so the headings were the keys to the records and the records were surrogates for documents. “the elements of a bibliographic record . . . were designed to be read and comprehended by human beings, not by machines”38; established headings are not an exception. one of their basic characteristics was the precondition that they were unique in the context of a specific catalog, thereby avoiding ambiguity. in every case of synonymy, qualifiers (such as date of birth or profession) were added to disambiguate, while the names also played the role of a unique identifier. from this process, an issue emerges: the information that appears on the document has changed and the controlled name may be completely different from the name on the resource. this means that the cataloger performs a transformation of the information, and this transformation carries two dangers. first, by changing the name, there is the possibility of assigning the entity behind the name to a wrong entity. second, by disturbing the correspondence between the information on the resource and the information on the record of the resource, the record becomes a problematic surrogate of the resource. to surpass this obstacle, traditional catalogs split the information into two different areas: one with the established forms, i.e., the headings; and the second with the purely descriptive information, i.e., the information that must be transcribed from the resource. this is the reason why traditional library catalogs put much effort into transcribing information from resources and very detailed guidelines have been developed. on the other hand, current approaches on metadata creation (such as dublin core) seem to underestimate the importance of descriptive information while concentrating on the established forms of names. but how can we be sure that different literals communicate the same meaning? does this kind of simplification, perhaps, cause problems regarding the integrity of the information? the names are not just sequences of characters (i.e., strings), but they carry latent information. it is known that there are women who wrote using male names (for example mary ann evans wrote as george eliot) and men who wrote by using female names. there are also nicknames for groups (e.g., “richard henry” is a pseudonym for the collaborative works of richard butler and henry chance newton), etc. therefore, it is important not to ignore names and the forms in which they appear on the resources, but to model them in such a way that integration between authorities and descriptive information is feasible, and the names are efficiently machine-processable. integrating authorities with descriptive information as we have already stated, traditional library catalogs are built on the dichotomy between description and access points. this analysis aims to bring descriptive information and authorities closer, i.e. to connect the access point of catalogs with the description of the resource. the basic principle of the model presented in this section is to promote each verbal (lexical) representation of a name to a nomen, whether this form of the name derives from a controlled vocabulary or not. in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 28 in the cases that this form appears in a specific vocabulary, appropriate properties could be used to indicate such a relation. in this section, some representative examples are presented. it is important to note, once again, that every node and relation in the following figures could (and must, in the context of the semantic web) be identified by a uri, except for the values in rectangles, which are rdf simple literals and therefore cannot be the subjects of further expansion. thus, the concatenation is the following: every individual (instance of the relevant class) acquires a uri. every individual is connected through the “has appellation” property (acquires uri) to a nomen (also acquires uri) and these nomens end up connected to a plain rdf literal, which is in natural language wording and cannot be subjected to further analysis. place names the problem of place as an attribute in frbr and frad has also been analyzed in the background analysis of the current paper, specifically in the subsection “the impact of the representation scheme’s selection: rdf versus er.” here, a solution to this problem that is compatible with the frbr/rda solution is proposed. by promoting every nomen of a place to an rdf node, there is the option of referring to the entity of place as a whole or to a specific appellation of this entity. so, the relation (property in the context of rdf) between the subjects of a work could be indicated by connecting work x with place z. on the other hand, according to rule 2.8.1.4 of rda, the place of publication for the manifestation must be transcribed as it appears on the source of information. but following the connections presented in figure 3, it is easy to assume that this specific nomen corresponds to the same entity, i.e., to the same place. figure 3. place information technology and libraries | june 2016 29 personal names in the section “names, entities and identities,” we analyzed many of the problems associated with personal names. here, a model is presented where the work (and expression) is connected directly with the author, whereas manifestation is connected with a specific appellation, i.e., nomen, of this author. figure 4. statements of responsibility rda rule 2.4.1.4 states, “transcribe a statement of responsibility as it appears on the source of information.” but occasionally the statement of responsibility may contain phrases and not just names. in these cases, a solution similar to the metadata object description schema (mods) could be implemented where, if needed, the statement of responsibility is included in the note element using the attribute type="statement of responsibility." titles the management of titles in frbr and rda indicates a different point of view between the two standards. according to rda there is no title for the expression,39 and, as taniguchi states, this is a “significant difference between frbr and rda.”40 bibframe abides by the same principle of downgrading expression, since it entangles expression with work in an indivisible unit. in this regard, bibframe is closer to rda than to frbr. the notion of work has nothing to do with specific languages, even in the case when the work is a written text. therefore the assignment of the title of work to a specific appellation is an unnecessary limitation. on the contrary, the title of a manifestation is derived by a specific in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 30 resource. we argue that between these two poles there is the title of expression, which could stand as a uniform title per language. figure 5. titles v of bibliographic records and cataloging rules resource description in the domain of lis—from cutter’s era to the present day—emphasizes static linear textual representations. according to the rda “0.1 key features,” “in rda, there is a clear line of separation between the guidelines and instructions on recording data and those on the presentation of data. this separation has been established in order to optimize flexibility in the storage and display of the data produced using rda. guidelines and instructions on recording data are covered in chapters 1 through 37; those on the presentation of data are covered in appendices d and e.” but the tables in the relative appendices (d and e) contain guidelines that are mainly concentrated on punctuation issues, and they do not take into consideration the dynamics of current interactive user interface capabilities. as coyle and hillmann comment, “there are instructions for highly structured strings that are clearly not compatible with what we think of today as machine-manipulable data.”41 it is rather like producing high-tech cards: rda is faithful information technology and libraries | june 2016 31 to the classical text-centric approaches that produce bibliographic records as a linear enumeration of attributes; thus, rda can be likened to a new suit that is quite old fashioned. traditional catalogs (from card catalogs to opacs and repository catalogs) were built upon the principle of creating autonomous records. frbr set this principle, i.e. one record for each resource, under dispute, while linked data abolishes it. this way, a gigantic graph of statements is created, while a certain part of these statements (not always the same) responds to or describes the desired information. thus, a more sophisticated method emerges, if not makes itself imposed, for showing the results. therefore, the issue is not to present a record that describes a specific resource, since this conceptualization tends to be obsolete altogether. consequently, the visualization has to be different while in dependence with the data structure as well as the available interface of the searcher. in this context, the analysis of this study tries to keep in balance the machine-processable character of rdf that builds on identifiers (uris), while paying attention to the linguistic representation of entities. we argue that the balance between them will result in highly accurate and efficient representations for both humans and software agents. let us consider the model for titles that has been introduced in this study. according to frbr, “if the work has appeared under varying titles (differing in form, language, etc.), a bibliographic agency normally selects one of those titles as the basis of a ‘uniform title’ for purposes of consistency in naming and referencing the work.”42 rda treats the case in a very similar way: rule 5.1.3 states, “the term ‘title of the work’ refers to a word, character, or group of words and/or characters by which a work is known. the term ‘preferred title for the work’ refers to the title or form of title chosen to identify the work. the preferred title is also the basis for the authorized access point representing that work”. in this study, we consider the aforementioned statements as a projection that springs from the days when records were static textual descriptions independent of interfaces. nowadays we are moving towards a much clearer distinction between the entity and its names. this is reflected in figure 5, in which the connection between a work and its author has nothing to do with specific names (appellations) but is based on uris. the selection of the appropriate name as a title for the specific work could be based on certain criteria such as the language of the interface: in this case, the title of the work will be the title of the user interface language, and if this is not possible (i.e. there is no title label in this language), then it could be the title of the catalog’s default language. following the kind of modeling proposed in the current study, the visualizations of data become more flexible and efficient in a variety of dynamic ways. hence, we can isolate and display nodes and their connections, correlate them with the interface language or screen size (i.e., mobile phone or pc), create levels relative to the desired depth of analysis, personalize them upon the user’s request or habits, and so on. also, it becomes possible to display the data in forms other than textual. “as a result, humans, with their great visual pattern recognition skills, can comprehend data tremendously faster and more effectively through visualization than by reading the numerical or textual representation of the data.”43 in the name of the name: rdf literals, er attributes, and the potential to rethink the structures and visualizations of catalogs | peponakis |doi:10.6017/ital.v35i2.8749 32 as we have already mentioned, the syntax and the semantics are always going to have a close relationship, but it is crystal clear that, now more than ever, the current semantic web standards allow for greater flexibility. as dunsire et al. put it, the rdf approach is very different from the traditional library catalog record exemplified by marc21, where descriptions of multiple aspects of a resource are bound together by a specific syntax of tags, indicators, and subfields as a single identifiable stream of data that is manipulated as a whole. in rdf, the data must be separated out into single statements that can then be processed independently from one another; processing includes the aggregation of statements into a record-based view, but is not confined to any specific record schema or source for the data. statements or triples can be mixed and matched from many different sources to form many different kinds of user-friendly displays.44 in this framework, cataloging rules must reexamine their instructions in light of the new opportunities offered by technological advancements. discussion naming is a vital issue for human cultures. names are not random sequences of characters or sounds that stand just as identifiers for the entities, but they also have socio-cultural meanings and interpretations. recently, out of “political correctness” and fear of triggering racism, sweden changed the names of bird species that could potentially offend, such as “gypsy bird” and “negro.”45 therefore we cannot treat names just as random identifiers. in this study we examined how, instead of describing indivisible resources, we could describe entities that appear in a variety of names on various resources. we proposed a method for connecting the names to the entities they represent and, at the same time, we documented the provenance of these names by connecting specific resources with specific names. we illustrated how to establish connections between entities, connections between an entity and a specific name of another entity, as well as connections between one name and another name concerning one or two entities. in the proposed framework, we maintain the linguistic character of naming while modeling the names in a machine-processable way. this formalism allows for a high level of expressiveness and flexible descriptions that do not have a static, text-centric orientation, since the central point is not the establishment of the text values (i.e., heading) but the meaning of our statements. this study has shown that it is important to have the possibility to establish relationships both between entities and between specific appellations (nomens in the context of this study) of these entities. to achieve this we promoted every appellation to an rdf node. this is not something unheard of in the domain of rdf since this approach has also been adopted by w3c for the development of skos-xl.46 frbroo, which is another interpretation of increasing influence in the wider context of the fr family, adopts the same perspective. 47 frbroo also gives the option to connect a specific name with a resource through the property “r64 used name (was name used information technology and libraries | june 2016 33 by)” or to connect a name with someone who uses this specific name through the property “r63 named (was named by).” murray and tillett state that “cataloging is a process of making observations on resources”48; hence, the production of records is the result of the judgments during this process. but in the context of traditional descriptive cataloging, the cataloger was not required to judge information in any way other than its category, i.e. to characterize whether the x set of characters corresponded to the name of an author, publisher, or place and so on. there was no obligation of assigning a particular name to a specific author, publisher, or place. in our approach, the cataloger interprets the information and supports the catalog’s potential to deliver added-value information. moreover, the initial information remains undifferentiated; hence, there is always the option of going back in order to generate new interpretations or validate existing ones. in recent years, there has been a significant increase in the attention given to multi-entity models of resource description.49 in this new environment, “the creation of one record per resource seems a deficient simplification.”50 rdf allows the transformation of universal bibliographic control to a giant global graph.51 in this manner, current approaches on resource description “cannot be considered as simple metadata describing a specific resource but more like some kind of knowledge related to the resource.”52 indeed, this knowledge can be computationally processable and exploitable. yet, to achieve this, “catalogers can only begin to work in this way if they are not held bound by the traditional definitions and conceptualizations of bibliographic records.”53 one critical issue is the isolation of parts (sets of statements) of this “giant graph” and the linking of these parts with something else; indeed, theory on this topic is starting to emerge.54 this is very essential because it allows for the creation of ad hoc clusters (i.e. the usage of a specific identity for an entity with all the names that have been assigned to this identity, in our context), which could be used as a set to link to some other entity. as a final remark, we could say that authorities manage controlled access points. in the semantic web, every uri is a controlled access point, and hence, the discrimination between description and authorities acquires a new meaning. in the context of machine-processable bibliographic data, the aim is to connect these two, i.e. the authorities with the description, and examine how one can support the other. however, since the emphasis is not on their individual management, we are drawn away from a mentality of ‘descriptive information versus access points” and towards one of “descriptive information as an access point.” acknowledgement the author wishes to thank henry scott

libraries | march 2012 3 congratulations lita and information technology and libraries. since the early days of the internet, i’ve been continually struck by the incredible opportunities that it offers organizations concerned with the creation, organization, and dissemination of knowledge to advance their core missions in new and more effective ways. libraries and librarians were consistently early and aggressive in recognizing, seizing, and advocating for these opportunities, though they’ve faced—and continue to face—enormous obstacles ranging from copyright laws to the amazing inertia of academic traditions in scholarly communication. yet the library profession has been slow to open up access to the publications of its own professional societies, to take advantage of the greater reach and impact that such policies can offer. making these changes is not easy: there are real financial implications that suddenly seem very serious when you are a member of a board of directors, charged with a fiduciary duty to your association, and you have to push through plans to realign its finances, organizational mission, and goals in the new world of networked information. so, as a long-time lita member, i find it a great pleasure to see lita finally reach this milestone with information technology and libraries (ital) moving to fully open-access electronic distribution, and i congratulate the lita leadership for the persistence and courage to make this happen. it’s a decision that will, i believe, make the journal much more visible, and a more attractive venue for authors; it will also make it easier to use in educational settings, and to further the interactions between librarians, information scientists, computer scientists, and members of other disciplines. on a broader ala-wide level, ital now joins acrl’s college & research libraries as part of the american library association’s portfolio of open-access journals. supporting ital as an open-access journal is a very good reason indeed to be a member of lita. clifford lynch (clifford@cni.org) is executive director, coalition for networked information. mailto:clifford@cni.org eclipse editor for marc records bojana dimić surla information technology and libraries | september 2012 65 abstract editing bibliographic data is an important part of library information systems. in this paper we discuss existing approaches in developing user interfaces for editing marc records. there are two basic approaches: screen forms that support entering bibliographic data without knowledge of the marc structure, and direct editing of marc records shown on the screen. this paper presents the eclipse editor, which fully supports editing of marc records. it is written in java as an eclipse plug-in, so it is platform-independent. it can be extended for use with any data store. the paper also presents a rich client platform (rcp) application made of a marc editor plug-in, which can be used outside of eclipse. the practical application of the results is integration of the rcp application into the bisis library information system. introduction an important module of every library information system (lis) is one for editing bibliographic records (i.e., cataloguing). most library information systems store their bibliographic data in a form of marc records. some of them support cataloging by direct-editing of marc record; others have a user interface that enables entering bibliographic data by a user who knows nothing about how marc records are organized. the subject of this paper is user interfaces for editing marc records. it gives software requirements and analyzes existing approaches in this field. as the main part of the paper, we present the eclipse editor for marc records, developed at the university of novi sad, as a part of the bisis library information system. eclipse uses the marc 21 variant of the marc format. the remainder of this paper describes the motivation for the research, presents the software requirements for cataloging according to marc standards, and provides background on the marc 21 format. it also describes the development of the bisis software system, reviews the literature concerning tools for cataloging, and analyzes existing approaches in developing user interfaces for editing marc records. the results of the research are presented in the final section, which describes the functionality and technical characteristics of the eclipse marc editor. the rich client platform (rcp) version of the editor, which can be used independently of eclipse, is also presented. motivation the motivation for this paper was to provide an improved user interface for cataloging by the marc standard that will lead to more efficient and comfortable work for catalogers. bojana dimić surla (bdimic@uns.ns.ac.yu) is an associate professor, university of novi sad, serbia. eclipse editor for marc records |surla 66 there are two basic approaches in developing user interfaces for marc cataloging. the first approach includes using a classic screen form made of text fields and labels with the description of the bibliographic data, without marc standard indication. the second approach is direct editing of a record that is shown on the screen. those two approaches will be discussed in detail in “existing approaches in developing user interfaces for editing marc records” below. the current editor in the bisis system is a mixture of these two approaches—it supports direct editing, but data input is done via text field, which opens on double click.1 the idea presented in this paper is to create an editor that overcomes all drawbacks of previous solutions. the approach taken in creating the editor was direct record-editing with real-time validation and no additional dialogs. software requirements for marc cataloging the user interface for marc cataloging needs to support following functions: • creating marc records that satisfy constraints proposed by the bibliographic format • selecting codes for field tags, subfield names, and values of coded elements, such as character positions in leader and control fields, indicators, and subfield content • validating entered data • access to data about the marc format (a “user manual” for marc cataloging) • exporting and importing created records • providing various previews of the record, such as catalog cards background marc 21 as was previously mentioned, the eclipse editor uses the marc 21 variant. marc 21 consists of five formats: bibliographic data, authority data, holdings data, classification data, and community information.2 marc 21 records consist of three parts: record leader, set of control fields, and set of data fields. the record leader content, which follows the ldr label, includes the logical length of the record (first five characters) and the code for record status (sixth character). after the record leader, there are control fields. every control field is written in new line and consists of the threecharacter numeric tag and content of the control field. the content of the control field can be a single datum or a set of fixed-length bibliographic data. control fields are followed by data fields in the record. every line in the record that contains a data field consists of a three-character numeric tag, the value for the first and the second indicator—or the number sign (#) if indicators are not defined for the field—and the list of subfields that belong to the field. information technology and libraries | september 2012 67 detailed analysis of marc 21 shows that there are some constraints on the structure and content of the marc 21 record. constraints on the structure define which fields and subfields can appear more than once in the record (i.e., are the fields and subfields repeatable or not), the allowed length of the record elements, and all the elements of the record defined by marc 21. constraints on the record content are defined on the content of the leader, indicators, control fields and subfields. moreover, some constraints connect more elements in the record (when the content of one element depends on the content of the other element in the record). an example of constraint on the structure for data field 016 is that the field has the first indicator whereas the second indicator is undefined. the field 016 can have subfields a, z, 2, and 8, of which z and 8 are repeatable. bisis the results presented in this paper belong to the research on the development of the bisis library information system. this system, which has been in development since 1993, is currently in its fourth version. the editor for cataloging in the current version of bisis was the starting point for the development of eclipse, the subject of this paper. 3 apart from an editor for cataloging, the bisis system has a module for circulation and an editor for creating z39.50 queries.4 the indexing and searching of bibliographic records was implemented using the lucene text server.5 as a part of the editor for cataloging, we developed the module generating various reports and catalog cards from marc records.6 bisis also supports creating an electronic catalog of unimarc records on the web, where the input of bibliographic data can be down without knowing unimarc but the entered data are mapped to unimarc and stored in the bisis database.7 the recent research within the bisis project relates to its extension for managing research results at the university of novi sad. for that purpose, we developed the current research information system (cris) on the recommendation of the nonprofit organization eurocris.8 the paper “cerif compatible data model based on marc 21 format” gives the proposal for the common european research information format (cerif), a compatible data model based on marc 21. in this model, a part of the cerif data model that relates to research results is mapped to marc 21. furthermore, on the basis of this model, research management at the university of novi sad was developed.9 the paper “cerif data model extension for evaluation and quantitative expression of scientific research results” explains the extension of cerif for evaluation of published scientific research. the extension is based on the semantic layer of cerif, which enables classification of entities and their relationships by different classification schemas.10 the current version of the bisis system is based on a variant of the unimarc format. the development of the next version of bisis, which will be based on marc 21, is in progress. the first task was migrating existing unimarc records.11 the second task is developing the editor for marc 21 records, which is the subject of this paper. eclipse editor for marc records |surla 68 cataloging tools an editor for cataloging is a standard part of a cataloger’s workstation and the subject of numerous studies. lange describes the cataloging development process from handwritten cataloging cards, to typewriters (first manual then electronic), to the appearance of marc records and pc-based cataloger’s workstations.12 leroya and thomas debate the influence of web development on cataloging. they stress that the availability of information on the web, as well as the possibility that more applications can be opened in the same time in different windows, greatly influence the process of creating bibliographic records. their paper also indicates that there are some problems that result from using large numbers of resources from the web, such as errors that arise from copy-paste methods. consequently, there is a need for automatic check of spelling errors and the possibility of a detailed review by a cataloger during editing.13 khurshid deals with general principles of the cataloger’s workstation, its configuration, and its influence on a cataloger’s productivity. in addition to efficient access to remote and local electronic resources, khurshid includes record transfer through a network and sophisticated record editing as important functions of a cataloger’s workstation. furthermore, khurshid says it is possible to improve cataloging efficiency in the windows-based cataloger’s workstation by finding bibliographic records in other institutions and cutting and pasting lengthy parts of the record (such as summary notes) to their own catalog.14 existing approaches in developing user interfaces for editing marc records the basic source for this analysis of existing user interfaces for editing marc records was the official site for marc standards of the library of congress in addition to scientific journals and conferences. the analysis of existing systems shows that there are two basic approaches in the implementation of editing marc records: 15 • entering bibliographic data in classic screen forms made of text fields and labels, which does not require knowledge of the marc format (concourse,16 koha,17 j-marc18) • direct editing of a marc record shown on the screen (marcedit,19 isismarc,20 catalis,21 polaris,22 marcmaker and marcbraker,23 exlibris voyager24). both of these approaches have advantages and disadvantages. the drawback of the first approach is that it provides a limited set of bibliographic data to edit, and the extension of that set implies changes to the application, or in the best cases changes in configuration. another problem is that there are usually a lot of text fields, text areas, combo boxes, and labels on the screen that need to be organized into several tabs or additional windows. this situation usually makes it difficult for the users to see errors or to connect different parts of the record when checking their work. moreover, all found solutions from the first group perform little validation of data entered by the user.25 one important advantage of the first approach is that the application can be used by a user information technology and libraries | september 2012 69 who is not familiar with the standard, thus the need for access to marc data can be avoided (one of functions listed “marc 21” above). as for second approach, editing a marc record directly on the screen overcomes the problem of extending the set of bibliographic data to enter. it also enables users to scan entered data and check the whole record, which appears on the screen. users can also copy and paste parts of records from other resources into the editor. however, a majority of those applications are actually editors for editing marc files that are later uploaded in some database or transformed in some other format (marcedit, marcmaker and marcbreaker, polaris), and they usually support little or no data validation.26 they allow users to write anything (i.e., the record structure is not controlled by the program), and only validate at the end of the process when uploading or transforming the record. among those editors there are those, such as catalis and isismarc, that present the marc record as a table. they support the control of structure, but the record presented in this way is usually too big to fit on the screen, so it is separated into several tabs. an important function of editing marc records is selecting code for coded elements that can be positioned in the leader or control field, value of the indicator, or value of the subfield. there are also field tags or subfield codes that sometimes need to be selected for addition to a record. all analyzed editors provide additional dialogs for picking this code that require the user to constantly open and close dialogs, which sometimes can be annoying for the user. one important fact about editors in the second group is that they can be used only by a user who is familiar with marc, so access to the large set of marc element descriptions can make the job easier. some of the mentioned systems provide descriptions of the fields and subfields (e.g., isismarc), but most of them do not. findings the editor for marc records was developed as a plug-in for eclipse; therefore it is similar to eclipse’s java code editors. as the editor is written in java, it is platform-independent. the main part of this editor was created using oaw xtext framework for developing textual domain-specific languages.27 it was created using model-driven software development by specifying the model of marc record in a form of xtext grammar and generating the editor. all main characteristics of the editor were generated on the basis of the specification of constraints and extensions of the xtext grammar—therefore all changes to the editor can be realized by changing the specification. moreover, this editor can be easily adjusted for any database by using the concept of extension and extension point in the eclipse plug-in. we make this application independent of eclipse by using rich client platform (rcp) technology. this editor is implemented for marc 21 bibliographic and holdings formats. user interface eclipse editor for marc records |surla 70 figure 1 shows the editor opened within eclipse. the main area is marked with “1”—it shows the marc 21 file that is being edited. that file contains one marc 21 bibliographic record. the tags of the fields and subfields codes are highlighted in the editor, which contributes to presentation clarity. the area marked with “2” serves for listing the errors in the record, that is, nonvalid elements entered in the record. the area marked with “3” shows data about marc 21 in a tree form. this part of the screen has two other possible views: a marc 21 holdings format tree and a navigator, which is the standard eclipse view for browsing resources for the opened project. the actions available for creating a record are available in the cataloging menu and on the cataloging toolbar, which is marked with “4.” these are actions for previewing the catalog card, creating a new bibliographic record, loading a record from a database (importing the record), uploading a record to a database (exporting the record), and creating a holdings record for this bibliographic record. figure 1. eclipse editor for marc records in the eclipse editor for marc, selecting codes is enabled without opening additional dialogs or windows (figure 2). that is a standard eclipse mechanism for code completion: typing ctrl + space opens the dropdown list with all possible values for the cursor’s current position. information technology and libraries | september 2012 71 figure 2. selecting codes record validation is done in real time, and every violation is shown while editing (figure 3). figure 3 depicts two errors in the record: one is a wrong value in the second character position in control field 008, and another is that two 100 fields were entered, which is a field that cannot be duplicated in a record. figure 3. validation errors rcp application of the cataloging editor as shown above, the editor is available as an eclipse plug-in, which raises the question of what a cataloger will do with all the other functions of the eclipse integrated development environment (ide). as seen in figures 1 and 3, there are a lot of additional toolbars and menus that not related eclipse editor for marc records |surla 72 to cataloging. the answer lies in rcp technology. rcp technology generates independent software applications on the basis of a set of eclipse plug-ins.28 the main window of an rcp application with additional actions is shown in figure 4. beside the cataloguing menu that is shown, the window also contains the file menu, which includes save and save as actions, as well as the edit menu, which includes undo and redu actions. all of these actions are also available via the toolbar. figure 4. rcp application conclusion the goal of this paper was to review current user interfaces for editing marc records. we presented two basic approaches in this field and analyzed of advantages and disadvantages of each. we then presented the eclipse marc editor, which is part of the bisis library software system. the idea behind eclipse is inputting structured marc data in the form similar to programming language editors. the author did not find this approach in the accessible literature. the rcp application of the presented editor will find its practical application in future versions of the bisis system. it represents an upgrade of the existing editor and a starting point for forming the version of the bisis system that will be based on marc 21. the acquired results can also be information technology and libraries | september 2012 73 used for the input of other data into the bisis system, including data from the cris system used at the university of novi sad. this paper shows that eclipse plug-in technology can be used for creating end user applications. the development of applications with the plug-in technology enables the use of a big library of created components from the eclipse user interface, whereby writing source code is avoided. additionally, the plug-in technology enables the development of extendible applications by using the concept of the extension point. in this way, we can create software components that can be used by a great number of different information systems. by using the concept of “extension point,” the editor can be extended by the functions that are specific for a data store. an extension point was created for export and import of marc records, which means the marc editor plug-in can be used with any database management system by extending this extension point in eclipse plug-in technology. future work in the development of the eclipse marc editor is to implement support for additional marc formats, for authority and classification data, and for community information. these formats propose the same record structure but have different constraints on the content and different sets of fields and subfields, as well as different codes for character positions and subfields. therefore the appearance of the editor will remain the same. the only difference will be the specification of the constraints and codes for code completion. another interesting topic for discussion is considering implementation of other modules of library information systems in eclipse plug-in technology.

information workers, web/semantic web technologists, and the general public understand, explain, and manage resource description tasks by creating, counting, measuring, classifying, and otherwise arranging descriptions of cultural heritage resources within the bibliographic universe and beyond it. a significant effort is made to update the nineteenth-century mathematical and scientific ideas present in traditional cataloging theory to their twentiethand twenty-first-century counterparts. there are two key elements in this approach: (1) a technique for diagrammatically depicting and manipulating large quantities of individual and grouped bibliographic entities and the relationships between them, and (2) the creation of resource description exemplars (problem–solution sets) that are intended to play theoretical, pedagogical, and it system design roles. to the reader: this paper presents a major re-visioning of cataloging theory, introducing along the way a technique for depicting diagrammatically large quantities of bibliographic entities and the relationships between them. as many details of the diagrams cannot be reproduced in regularly sized print publications, the reader is invited to follow the links provided in the endnotes to pdf versions of the figures. c ataloging—the systematic arrangement of resources through their descriptions that is practiced by libraries, archives, and museums (i.e., cultural heritage institutions) and other parties1—can be placed in an advanced, twenty-first-century context by updating its preexisting scientific and mathematical ideas with their more contemporary versions. rather than directing our attention to implementation-oriented details such as metadata formats, database designs, and communications protocols, as do technologists pursuing bottom-up web and semantic web initiatives, in ronald j. murray and barbara b. tillett cataloging theory in search of graph theory and other ivory towers object: cultural heritage resource description networks this paper we will define a complementary, top-down approach. this top-down approach focuses on how catalogers, other cultural heritage information workers, web/ semantic web technologists, and the general public have understood, explained, and managed their resource description tasks by creating, counting, measuring, classifying, and otherwise arranging descriptions of cultural heritage resources within and beyond the bibliographic universe. we go on to prescribe what enlargements of cataloging theory and practice are required such that catalogers and other interested parties can describe pages from unique, ancient codices as readily as they might describe information elements and patterns on the web. we will be enhancing cataloging theory with concepts from communications theory, history of science, graph theory, computer science, and from the hybrid field of anthropology and mathematics called ethnomathematics. employing this strategy benefits two groups: ■■ workers in the cultural heritage realm, who will acquire a broadened perspective on their resource description activities, who will be better prepared to handle new forms of creative expressions as they appear, and who will be able to shape the development of information systems that support more sophisticated types of resource descriptions and ways of exploring those descriptions. to build a better library system (perhaps an n-dimensional, n-connected system?), one needs better theories about the library collections and the people or groups who manage and use them. ■■ the full spectrum of people who draw on cultural heritage resources: scholars, creatives (novelists, poets, visual artists, musicians, and so on), professional and technical workers, students, and other people or groups pursuing specific or general, long or short-term interests, entertainment, etc. to apply a multidisciplinary perspective to the processes by which resource description data (linked or otherwise) are created and used is not an ivory tower exercise. our approach draws lessons from the debates on why, what, and how to describe physical phenomena that were conducted by physicists, engineers, software developers (and their historian and philosopher of science observers) during the evolution of high-energy physics. during that time, intensive debates raged over theory and observational/experimental data, the roles of theorists, experimenters, and instrument builders, instrumentation, and hardware/software system design.2 accommodating the resulting scientific approaches to description, collaboration, and publishing has required the creation of information technologies that have had and continue to have world-shaking effects. ronald j. murray (rmur@loc.gov) is a digital conversion specialist in the preservation reformatting division, and barbara b. tillett (btil@loc.gov) is the chief of the policy and standards division at the library of congress. cataloging theory in search of graph theory and other ivory towers | murray and tillett 171 descriptions—accounts or representations of a person, object, or event being drawn on by a person, group, institution, and so on, in pursuit of its interests. given this definition, a person (or a computation) operating from a business rules–generated institutional or personal point of view, and executing specified procedures (or algorithms) to do so, is an integral component of a resource description process (see figure 1). this process involves identifying a resource’s textual, graphical, acoustic, or other features and then classifying, making quality and fitness for purpose judgments, etc., on the resource. knowing which institutional or individual points of view are being employed is essential when parties possessing multiple views on those resources describe cultural heritage resources. how multiple resource descriptions derived from multiple points of view are to be related to one another becomes a key theoretical issue with significant practical consequences. ■■ niels bohr’s complementarity principle and the library in 1927, the physicist niels bohr offered a radical explanation for seemingly contradictory observations of physical phenomena confounding physicists at that time.6 according to bohr, creating descriptions of nature is the primary task of the physicist: it is wrong to think that the task of physics is to find out how nature is. physics concerns what we can say about nature.7 descriptions that appear contradictory or incomparable may in fact be signaling deep limitations in language. bohr’s complementarity principle states that a complete description of atomic-level phenomena requires descriptions of both wave and particle properties. this is generally understood to mean that in the normal language these physics research facilities and their supporting academic institutions are the same ones whose scientific subcultures (theory, experiment, and instrument building) generated the data creation, management, analysis, and publication requirements that resulted in the creation of the web. in response to this development, we have come to believe that cultural heritage resource description (i.e., the process of identifying and describing phenomena in the bibliographic universe as opposed to the physical one) must now be as open to the concepts and practices of those twenty-first-century physics subcultures as it had been to the natural sciences during the nineteenth century.3 we have consequently undertaken an intensive study of the scientific subcultures that generate scientific data and have identified four principles on which to base a more general approach to cultural heritage resource description: 1. observations 2. complementarity 3. graphs 4. exemplars the cultural heritage resource description theory to follow proposes a more articulated view of the complex, collaborative process of making available—through their descriptions—socially relevant cultural heritage resources at a global scale. we will demonstrate that a broader understanding of this resource description process (along with the ability to create improved implementations of it) requires integrating ideas from other fields of study, reaching beyond it system design to embrace larger issues. ■■ cataloging as observation as stated in the oxford english dictionary, an observation is: the action or an act of observing scientifically; esp. the careful watching and noting of an object or phenomenon in regard to its cause or effect, or of objects or phenomena in regard to their mutual relations (contrasted with experiment). also: a measurement or other piece of information so obtained; an experimental result.4 following the scientific community’s lead in striving to describe the physical universe through observations, we adapted the concept of an observation into the bibliographic universe and assert that cataloging is a process of making observations on resources. human or computational observers following institutional business rules (i.e., the terms, facts, definitions, and action assertions that represent constraints on an enterprise and on the things of interest to the enterprise)5 create resource figure 1. a resource description modeled as a business ruleconstrained account of a person, object, or event 172 information technology and libraries | december 2011 purpose, its reformatting, and its long-term preservation must take into consideration that resource’s physical characteristics. having things to say about cultural heritage resources—and having many “voices” with which to say them—presents the problem of creating a well-articulated context for library-generated resource descriptions as well as those from other sources. these contextualization issues must be addressed theoretically before implementation-level thinking, and the demands of contextualization require visualization tools to complement the narratives common to catalogers, scholars, and other users. this is where mathematics and ethnomathematics make their entrance. ethnomathematics is the study of the mathematical practices of specific cultural groups over the course of their daily lives and as they deal with familiar and novel problems.10 an ethnomathematical perspective on cultural heritage resource description directs one’s attention to the existence of simple and complex resource descriptions, the patterns of descriptions that have been created, and the representation of these patterns when they are interpreted as expressions of mathematical ideas. a key advantage of operating from an ethnomathematical perspective is becoming aware that mathematical ideas can be observed within a culture (namely the people and institutions who play key roles in observing the bibliographic universe) before their having been identified and treated formally by western-style mathematicians. ■■ resource description as graph creation relationships between cultural heritage resource descriptions can be represented as conceptually engaging and flexible systems of connections mathematicians call graphs. a full appreciation of two key mathematical ideas underlying the evolution of cataloging—putting things into groups and defining relationships between things and groups of things—was only possible after the founding, naming, and expansion of graph theory, which is a field of mathematics that emerged in the 1850s, and the eventual acceptance around 1900 of set theory, a field founded amid intense controversy in 1874. between the emergence of formal mathematical treatments of those ideas by mathematicians and their actual exploitation by cataloging theorists—or by anyone capable of considering library resource description and organization problems from a mathematical perspective—lay a gulf of more than one hundred years.11 it remained for scholars in the library world to begin addressing the issue. tillett’s 1987 work on bibliographic relationships and svenonius’s 2000 definition of bibliographic entities in set-theoretic terms that physicists use to communicate experimental results, the wholeness of nature is accessible only through the embrace of complementary, contradictory, and paradoxical descriptions of it. later in his career, bohr vigorously affirmed his belief that the complementarity principle was not limited to quantum physics: in general philosophical perspective, it is significant that, as regards analysis and synthesis in other fields of knowledge, we are confronted with situations reminding us of the situation in quantum physics. thus, the integrity of living organisms, and the characteristics of conscious individuals, and most of human cultures, present features of wholeness, the account of which implies a typically complementary mode of description. . . . we are not dealing with more or less vague analogies, but with clear examples of logical relations which, in different contexts, are met with in wider fields.8 within a library, there are many things catalogers, conservators, and preservation scientists—each with their distinctive skills, points of view, and business rules—can observe and say about cultural heritage resources.9 much of what these specialists say and do strongly affects library users’ ability to discover, access, and use library resources in their original or surrogate forms. while observations made by these specialists from different perspectives may lead to descriptions that must be accepted as valid for those specialists, a fuller appreciation of these descriptions calls for the integration of those multiple perspectives into a well-articulated, accessible whole. reflecting the perspectives of the library of congress directorates in which we work, the acquisitions and bibliographic access (aba) directorate and the preservation directorate, we assert that the most fundamental complementary views on cultural heritage resources involve describing a library’s resources in terms of their availability (from an acquisitions perspective), in terms of their information content (from a cataloging perspective), and in terms of their physical properties (from a preservation perspective). for example, in the normal languages used to communicate their results, preservation directorate conservators narrate their condition assessments and record simple physical measurements of library-managed objects—while at the same time preservation scientists in another section bring instrumentation to acquire optical and chemical data from submitted materials and from reference collections of physical and digital media. even though these assessments and measurements may not be comprehended by or made accessible to most library users, the information gathered possess a critical logical relationship to bibliographic and other descriptions of those same resources. key decisions regarding a library resource’s fitness for cataloging theory in search of graph theory and other ivory towers | murray and tillett 173 by the modeling technique. what is required instead is theory-based guidance of systems development, alongside theory testing and improvement through application use. if software development is not constrained by a tacit or explicit resource description theory or practice, graph or other data structures familiar to the historically less well-informed, those favored by an institution’s system designers and developers, or those familiar to and favored by implementation-oriented communities may be invoked inappropriately.18 given graph theory’s potentially overwhelming mathematical power—as evidenced by its many applications in the physical sciences, engineering, and computer science—investigations into graph theory and its history require close attention both to the history and evolving needs of the cultural heritage community.19 the unnecessary constraint on resource description theory formation occasioned by the use of e-r or oo modeling can be removed by dispensing with it system analysis tools and expressing resource description concepts in graph-theoretical terms. with this step, the very general elements (i.e., entities and relationships) that characterize e-r models and the more implementation-oriented ones in oo models are replaced by more mathematically flexible, theory-relevant elements expressed in graph-theoretical terms. the result is a “graph-friendly” theory of cultural heritage resource description, which can borrow from other fields (e.g., ethnomathematics, history of science) to improve its descriptive and predictive power, guide it system design and use, and, in response to users’ experiences with functioning systems, results in improved theories and information systems. graph theory in a cultural heritage context ever since the nineteenth century foundation of graph theory (though scholars regularly date its origins from euler’s 1736 paper)20 and its move from the backwaters of recreational mathematics to full field status by 1936, graph theory has concerned itself with the properties of systems of connections—nowadays regularly expressed as the mathematical objects called sets.21 in addition to its set notational form, graphs also are depicted and manipulated in diagrammatic form as dots/labeled nodes linked by labeled or unlabeled, simple or arrowed lines. for example, the graph x, consisting of one set of nodes labeled a, b, c, d, e, and f and one set of edges labeled ab, bd, de, ef, and fc, can be depicted in set notation as x = {{a b c d e f}, {ab bd de ef fc}} and can be depicted diagrammatically as in figure 2. when graphs are defined to represent different types of nodes and relationships, it becomes possible to create and discuss structures that can support cultural heritage resource description theory and application building. the following diagrams depict simple resource description identified those mathematical ideas in cataloging theory and developed them formally.12 then in 2009, we were able to employ graph theory (expressed in set-theoretical terms and in its highly informative graphical representation) as part of a broader historical and cultural analysis.13 cataloging theory had by 2009 haltingly embraced a new view on how resources in libraries have been described and arranged via their descriptions—an activity that in principle stretches back to catalogs created for the library of alexandria14—and how these structured resource descriptions have evolved over time, irrespective of implementation. murray’s investigation into this issue revealed that the increasingly formalized and refined rules that guided anglo-american catalogers had, by 1876, specified sophisticated systems of cross-references (i.e., connections between bibliographic descriptions of works, authors, and subjects)—systems whose properties were not yet the subject of formal mathematical treatment by mathematicians of the time.15 murray also found that library resource description structures—when teased out of their book and card and digital catalog implementations and treated as graphs—are arguably more sophisticated than those being explored in the world wide web consortium’s (w3c) library linked data initiative.16 implementation-oriented substitutes for graph theory cataloging theory has been both helped and hindered by the use of information technology (it) techniques like entity-relationship modeling (e-r, first used extensively by tillett in 1987 to identify bibliographic relationships in cataloging records) and object-oriented (oo) modeling.17 e-r and oo modeling may be used effectively to create information systems that are based on an inventory of “things of interest” and the relationships that exist between them. unfortunately, the things of interest in cultural heritage institutions keep changing and may require redefinition, aggregation, disaggregation, and re-aggregation. e-r and oo modeling as usually practiced are not designed to manage the degree and kind of changes that take place under those circumstances. when trying to figure out what is “out there” in the bibliographic universe, we assert that focus should first be placed on identifying and describing the things of interest, what relationships exist between them, and what processes are involved in the creation, etc., of resource descriptions. having accomplished this, attention can then be safely paid to defining and managing information deemed essential to the enterprise, that is, undertaking it system analysis and design. but when an it-centric modeling technique becomes the bed on which the resource description theory itself is constructed, the resulting theory will be driven in a direction that is strongly influenced 174 information technology and libraries | december 2011 of the resources they describe. figure 4’s diagrammatic simplicity becomes problematic when large quantities of resources are to be described, when the number and kinds of relationships recorded grows large, and when more comprehensive but less-detailed views of bibliographic relationships are desired. to address these problems in a comprehensive fashion, we examined similar complex description scenarios in the sciences and borrowed another idea from the physics community—paper tool creation and use. ■■ paper tools: graph-aware diagram creation paper tools are collections of symbolic elements (diagrams, characters, etc.), whose construction and manipulation are subject to specified rules and constraints.23 berzelian chemical notation (e.g., c6h12o6) and—more prominently—feynman diagrams like those in figure 5 are familiar examples of paper tool creation and use.24 creating a paper tool resource diagram requires that the rules for creating resource descriptions be reflected in diagram elements, properties of diagram elements, and drawing rules that define how diagram/symbolic elements are connected to one another (e.g., the formula c6h12o6 specifies six molecules of carbon, twelve of hydrogen, and six of oxygen). the detailed bibliographic information in figure 4 is progressively schematized in a graphs that are based on real-world bibliographic descriptions. nodes in the graphs represent text, numbers, or dates and relationships that can be nondirectional (as a simple line), unidirectional (as single arrowed lines) or bidirectional (as a double arrowed line). the all-in-one resource description graph in figure 3 can be divided and connected according to the kinds of relationships that have been defined for cultural heritage resources. this is the point where institutional, group, and individual ways of describing resources shape the initial structure of the graph. once constructed, graph structures like this and their diagrammatic representations are then interpreted in terms of a tacit or explicit resource description theory. in the case of graphs constructed according to ifla’s functional requirements for bibliographic records (frbr) standard,22 figure 3 can be subdivided into four frbr sub-graphs, yielding figure 4. the four diagrams depict the initial graph of cataloging data as four complementary frbr wemi (w–work, e–expression, m–manifestation, and i–item) graphs. note that the item graph contains the call numbers (used here to identify the location of the copy) of three physical copies of the novel. this use of call numbers is qualitatively different from the values found in the manifestation graph in that resource descriptions in this graph apply to the entire population of physical copies printed by the publisher. the descriptions contained in figure 4’s frbr subgraphs reproduce bibliographic characteristics found useful by catalogers, scholars, other educationally oriented end users, and to varying extents the public in general. once created, resource description graphs and subgraphs (in mathematical notation or in simple diagrams like figure 4) can proliferate and link in multiple and complex ways—in parallel with or independently figure 3. library of congress catalog data for thomas pynchon’s novel gravity’s rainbow, represented as an all-inone graph labeled c figure 2. a diagrammatic representation of graph x cataloging theory in search of graph theory and other ivory towers | murray and tillett 175 6 graph is now represented explicitly by a black dot in a ring in the more schematic paper tool version. resource descriptions are then represented in fixed colors and positions relative to the resource/ring: the worklevel resource description is represented by a blue box, expression by a green box, manifestation by a yellow box, and item by a red box. depicting one aspect of the frbr way that reflects frbr definitions of bibliographic things of interest and their relevant relationships. as a first step, the four wemi descriptions in figure 4 are given a common identity by linking them to a c node, as in figure 6. the diagram is then further schematized such that frbr description types and relationships are represented by appropriate graphical elements connected to other elements. the result shows how a frbr paper tool makes it much easier to construct and examine complex large-scale properties of resource and resource description structures (like figure 7, right side) without being distracted by textual and linkage details. the resource described

scholars—especially those creations that are dense with quotations, citations, and other types of direct and derived textual and graphical reference within and beyond themselves—are excellent environments for paper tool explorations and more generally, for testing of exemplars—solutions to the potentially complex problem of describing cultural heritage resources. ■■ exemplars the fourth principle in our cultural heritage resource description theory involves exemplar identification and analysis. according to the historian of science thomas s. kühn, exemplars are sets of concrete problems and solutions encountered during one’s education, training, and work. in the sciences, exemplar-based problem finding and solving involves mastery of relevant models, builds knowledge bases, and hones problem-solving skills. every student in a field would be expected to demonstrate mastery by learning and using their field’s exemplars. change within a scientific field is manifest by the need to modify old or create new exemplars as new problems appear and must be solved.26 a cultural heritage resource description theorist would, in addition to identifying and developing exemplars from real bibliographic data and other sources, want to speculate about possible resource/description configurations that call for changes in existing information technologies. to the theorist, it would be as important to find out what can’t be done with frbr and other resource description models at library, archive, museum, and internet scales, as it is to be able to explain routine item cataloging and tagging activities. discovering system limitations is better done in advance by simulating uncommon or challenging circumstances than by having problems appear later in production systems. model graphically, the descriptions closest to the black dot resource/slot are the most concrete and those furthest away the most abstract. (readers wishing to interpret frbr paper tool diagrams without reference to color values should note the strict ordering of wemi elements: w–e–m–i–resource/ring or resource/ring–i–m–e–w.) finally, to minimize element use when pairs of wemi boxes touch, the appropriate frbr linking relationship for the relevant pair of descriptions (as explicitly shown in the expanded graph) is implied but not shown. with appropriate diagramming conventions, the process of creating and exploring resource description complexes addresses combined issues of cataloging theory and institutional policy—and results in an ability to make better-informed judgments/computations about resource descriptions and their referenced resources. as a result, resource description graphs are readily created and transformed to serve theoretical—and with greater experience in thinking and programming along graph-friendly lines, practical—ends. one example of transformability would arise when exploring the implications of removing redundant portions of related resource descriptions as more copies of the same work are brought to the bibliographic universe. the frbr paper tool elements and the more articulated resource description graphs in figure 8 both depict the consequences of a practical act: combining resource descriptions for two copies of the same edition of the novel gravity’s rainbow.25 the top-most frbr diagram and its magnified section depict how the graph would look with a single item-level description, the call number for one physical copy. the bottom-most frbr diagram and its magnified section depict the graph with two item-level descriptions, the call numbers for two physical copies. a frbr paper tool’s flexibility is useful for exploring potentially complex bibliographic relationships created or uncovered by scholars—parties whose expertise lies in identifying, interrelating, and discussing creative concepts and influences across a full range of communicative figure 7. a frbr paper tool diagram element (left) and the less schematic frbr resource description graph it depicts (right) cataloging theory in search of graph theory and other ivory towers | murray and tillett 177 drawing diagrams. use case diagrams are secondary in use case work.28 as products of and guides for theory making, resource description exemplars have different origins and audiences than those for use cases. while use cases and exemplars offer perspectives that can support information system design, exemplars were originally introduced as theoretical entities by kühn to explain how theories and theory-committed communities can crystallize around problem-solution sets, how these sets also can serve as pedagogical tools, and why and when problem-solution sets get displaced by new ones. the proposed process of cultural heritage exemplar creation and use, followed by modification or replacement in the face of changes in the bibliographic universe draws on kühn’s and historian of science david kaiser’s interest in how work gets done in the sciences, in addition to their rejection of paradigms as eerie self-directing processes.29 exemplars are not use cases use cases are a software modeling technique employed by the w3c library linked data incubator group (lld xg) in support of requirements specification.27 kühnstyle exemplars are definitely not to be confused with use cases, which are requirements-gathering documents that contribute to software engineering projects. there is a wikipedia definition of a use case that describes its properties: a use case in software engineering and systems engineering, is a description of steps or actions between a user (or “actor”) and a software system which leads the user towards something useful. the user or actor might be a person or something more abstract, such as an external software system or manual process. . . . use cases are mostly text documents, and use case modeling is primarily an act of writing text and not figure 8. frbr paper tool diagram elements and the frbr resource description graphs they depict 178 information technology and libraries | december 2011 ■■ a webpage and its underlying, globally distributed, multimedia resource network, as it changes over time. such exemplars can be presented diagrammatically through the use of paper tools. this use of diagrams in support of conceptualization and information system design is deliberately patterned after professional data modeling theory and practice.31 paper tool–supported analyses of a nineteenth-century american novel (exemplar 1) and of eighteenth-century french poems drawn from state archives (exemplar 2) will be presented to illustrate how information system design and pedagogy can be informed by exemplary scholarly research and publication, combined with narrativized diagrammatic representations of bibliographic and other relationships in traditional and digital media. exemplar 1. from moby-dick to mash-ups—a print publication history and multimedia mash-up problem document the publication history of print copies of a literary work, identifying editorially driven content transfer across print editions along with content selection and transformation in support of multimedia resource creation. solution the solution to this descriptive problem relies heavily on placing resource descriptions into groups and then defining relationships within and across those groups— i.e., on graph creation. after locating a checklist that documented the publication history of the novel and after identifying key components of a moby-dick and orson welles–themed multimedia resource appropriation and transformation network, murray used the frbr paper tool along with additional connection rules to create a resource description diagram (rdd) that represented g. thomas tanselle’s documentation of the printing history (from 1851 to 1976) of herman melville’s epic novel, moby-dick.32 the resulting diagram provides a high-level view of a large set of printed materials—depicting concepts such as a creative work, the expression of the work in a particular mode of languaging (i.e., speech, sign, image), and more concrete concepts such as publications. to reduce displayed complexity, sets of frbr diagram elements were collapsed into green shaded squares representing entire editions/printings, yielding figure 9.33 the vertical axis represents the year of publication, starting with the 1851 printings at the top. connected squares the resulting network of connections in figure 9 can be interpreted in publishing terms. one line or two or more lines descending downwards from a printing’s green in addition, resource description structures specified in an exemplar can and should represent a more abstract treatment of a resource description and not just data or data structures engaged by end users. exemplars on hand and others to come cultural heritage resource description exemplars have been created over time as solutions to problems of resource description and later made available for use, study, mastery, and improvement. while not necessarily bound to a particular information technology, such as papyrus, parchment, index cards, database records, or rdf aggregations, resource description exemplars have historically provided descriptive solutions of physical resources whose physical and intellectual structure had originally been innovative solutions to describing, for example, ■■ a manuscript (individual and related multiples, published but host to history, imaginary, etc.); ■■ a monograph in one edition (individual and related multiples); ■■ a monograph in multiple editions (individual and related multiples); and ■■ a publication in multiple media, created sequentially or simultaneously. with the advent of electronic and then digital communications media, more complex resource description problem-solution sets have been called for as a response to enduringly or recently more sophisticated creative/ editorial decision-making and to more flexible print and digital information technology production capabilities. the most challenging problem-solution sets involve the assembly and cross-referencing of several multipart—and possibly multimedia—creative or editorially constructed works, such as the following: ■■ a work published as a monograph, but which has been reprinted and reedited; translated into numerous languages; supplemented by illustrations from multiple artists; excerpted and adapted as plays, an opera, comic books, and cartoon series; multimedia mash-ups; and has been directly quoted in paintings and other graphic arts productions, and has been the subject of dissertations, monographs, journal articles, etc. ■■ a continuing publication (individual and related multiple publications, special editions, name, publisher, editorial policy changes, etc.). ■■ a monograph whose main content is composed nearly entirely of excerpts from other print publications.30 ■■ a library-hosted multimedia resource and its associated resource description network. cataloging theory in search of graph theory and other ivory towers | murray and tillett 179 by paper tool diagram creation, analysis, and subsequent action, namely, ■■ connecting the squares (i.e., assigning at least one relationship to a printing) ensures access based on the relationship assigned; and ■■ parties located around the globe can examine a given connected or disconnected resource description network and develop strategies for enhancing its usefulness. the wealth of descriptive information available in the moby-dick exemplar illustrates how previous and future collaborative efforts between cultural heritage institutions and other parties have already generated resource descriptions that possess a network structure alongside its content. with a more graph-friendly and collaborative implementation, melville scholars, scholarly organizations,34 and enthusiasts could more effectively examine, discuss, and through their actions enhance the moby dick resource description network’s documentary, scholarly, and educational value. in its original form, the moby dick resource description diagram (and the exemplar it partially documents) only depicted full-length publications of melville’s work. as a test of the frbr paper tool’s ability to accommodate both traditional and modern creative expressions in individual and aggregate form—while continuing to serve theoretical, practical, and educational ends—murray added a resource description network for orson whales,35 square are interpreted to mean that the printing gave rise to one or more additional printings, which may occur in the same or later years. two or more lines converging on a green square from above indicate that the printing was created by combining texts from multiple prior printings—an editorial/creative technique similar to that used to construct the mash-ups published on the web. connecting unconnected squares tanselle’s checklist did not specify predecessor or successor relationships for each post–1851 printing. this often unavoidable, incomplete status is depicted in figure 9 as green squares that are ■■ not linked to any squares above it, i.e., to earlier printings; and/or ■■ not linked to any squares below it, i.e., to later printings; or ■■ connected islands, without a link to the larger structure. recognizing the extent of moby-dick printing disconnectedness in tanselle’s checklist and developing a strategy for dealing with it only by analyzing tanselle’s checklist would be extremely difficult. in contrast, the disconnectedness of the moby-dick resource description network, and its implications for search-based discovery based on following the depicted relationships is readily discernable in figure 9. the ease with which the disconnected condition can be assessed also hints at benefits to be gained by collaborative resource description supported figure 9. a moby-dick resource description diagram, depicting relationships between printings made between 1851–1976 (greatly reduced scale) 180 information technology and libraries | december 2011 darnton’s book can stand on its own as an exemplar for historical method, with the diagram providing additional diagrammatic support. solution 2 darnton’s analysis treated each poem found in the archives as an individual creative work,38 enabling the use of the frbr paper tool (as a bookkeeping device this time) instead of a tool designed to aggregate and describe archival materials. the resulting diagram is a more articulated frbr paper tool depiction of darnton’s poetry communication network, a section of which appears as figure 11. the depiction of the poetry communication network shown in figure 11 is composed of: ■■ tan squares that depict individuals (clerks, professors, priests, students, etc.) who read, discussed, copied, and passed along the poems. ■■ diagram elements that depict poetry written on scraps of paper (treated as resources) that were police custody, were admitted to having existed by suspects, or assumed to have existed by the police. if one’s theory and business rules permit it, paper tool drawing conventions can depict descriptions of lost and nonexistent but nonetheless describable resources. ■■ arrowed lines that represent relationships between a poem and the individuals who owned copies, those who created or received copies of the poem, etc.39 with darnton’s monograph to provide background information regarding the historical personages involved, relationships between the works and the people, document selection from archival fonds, and the point of view of the scholar, the resulting problem-solution set can: ■■ serve as enhanced documentation for darnton-style communication network analysis and discussion. ■■ serve as an exemplar for catalogers, scholars, and alex itin’s moby-dick-themed multimedia mash-up, to the print media diagram. the four-minute long orson whales multimedia mashup contains hundreds of hand-painted page images from the novel, excerpts from the led zeppelin song “moby dick,” parts of two vocal performances by the actor orson welles, and a video clip from welles’s motion picture citizen kane. the result is shown in figure 10.36 the leftmost group of descriptions in figure 10 depicts various releases of led zeppelin’s “moby dick.” the central group depicts the sources of two orson welles audio dialogues after they had been ripped (i.e., digitized from physical media) and made available online. the grouping on the right depicts the orson whales mash-up itself and collections of digital images of painted pages created from two printed copies of the novel. exemplar 2. poetry and the police—archival content identification and critical analysis problem examine archival collections and select, describe, and document ownership and other relationships of a set of documents (poems) alleged to have circulated within a loosely defined social group. solution 1 in his 2010 work, poetry and the police: communication networks in eighteenth-century paris, historian robert darnton studied a 1749 paris police investigation into the transmission of poems highly critical of the french king, louis xv. after combing state archives for police reports, finding and identifying scraps of paper once held as evidence, and collecting other archival materials, darnton was able to construct a poetry communication network diagram,37 which, along with his narrative account, identified a number of parties who owned, copied, and transmitted six of the scandalous poems and placed their activities in a political, social, and literary context. figure 10. a resource description diagram of alex itin’s moby-dick multimedia work, depicting the resources and their frbr descriptions. cataloging theory in search of graph theory and other ivory towers | murray and tillett 181 with all of the adaptations and excerpts extant within a specified bibliographic universe (such as the cataloging records that appear in oclc’s worldcat bibliographic database). resource description diagrams, created from real-world or theoretically motivated considerations, would then provide a diagrammatic means for depicting the precise and flexible underlying mathematical ideas that, heretofore unrecognized but nonetheless systematically employed, serve resource description ends. if the structure of a well-motivated and constructed resource description diagram subsequently makes data representation and management requirements that a given information system cannot accommodate, cataloging theorists and information technologists alike will then know of that system’s limitations, will work together on mitigating them, and will embark on improving system capabilities. ■■ cataloging theory, tool-making, education, and practice this modernized resource description theory offers new and enhanced roles and benefits for cultural heritage personnel as well as for the scholars, students, and those members of the general public who require support not just for searching, but also for collecting, reading, writing, collaborating, monitoring, etc.40 information systems that others who seek similar solutions to their problems with identifying, describing, depicting, and discussing as individual works documents ordinarily bundled within hierarchically structured archival fonds at multiple locations. ■■ a paper tool into a power tool there are limits to what can be done with a hand-drawn frbr paper tool. while murray was able to depict largescale bibliographic relationships that probably had not been observed before, he was forced to stop work on the moby-dick diagram because much of the useful information available could not fit into a static, hand-drawn diagram. we think that automated assistance in creating resource description diagrams from bibliographic records is required. with that capability available, cataloging theorists and parties with scholarly and pedagogical interests could interactively and efficiently explore how scholars and sophisticated readers describe significant quantities of analog and digital resources. it would then be possible and extremely useful to be able to initiate a scholarly discussion or begin a lecture by saying, “given a moby-dick resource description network . . . ” and then proceed to argue or teach from a diagram depicting all known printings of moby-dick—along figure 11. a section of darnton’s poetry communication network 182 information technology and libraries | december 2011 the value of non-euclidean geometry lies in its ability to liberate us from preconceived ideas in preparation for the time when exploration of physical laws might demand some geometry other than the euclidean.41 taking riemann to heart, we assert that the value of describing cultural heritage resources as observations organized into graphs and of enhancing and supplementing the resource description exemplars that have evolved over time and circumstance rests in opportunities for liberating the cultural heritage community from preconceived ideas about resource description structures and from longstanding points of view on those resources. having achieved such a goal, the cultural heritage community would then be ready when the demand came for resource description structures that must be more flexible and powerful than the traditional ones. given the unprecedented development of the web and the promise of bottom-up semantic web initiatives, we think that the time for the cultural heritage community’s liberation is at hand. ■■

across multiple points of view will be able to support those requirements. the complementarity of cosmological and quantum-level views cataloging theory formation and practice—two areas of activity that did not interest many outside of cultural heritage institutions—can now be understood as a much more comprehensive multilayered activity that is approachable from at least two distinct points of view. the approach presented in this paper represents a cosmological-level view on the bibliographic universe. this treatment of existing or imaginable large-scale configurations of cultural heritage resource descriptions serves as a complement to the quantum-level view of resource description, as characterized by it-related specificities such as character sets, identifiers, rdf triples, triplestores, etc. activities at the quantum level—the domain of semantic web technologists and others—yield powerful and relatively unconstrained information management systems. in the absence of cosmological-level inspiration or guidance, these systems have not necessarily been tested against nontrivial, challenging cultural heritage resource description scenarios like those documented in the above two exemplars. applying both views to the bibliographic universe would clearly be beneficial for all institutional and individual parties involved. if ever a model for multilevel, multidisciplinary effort was required, the history of physics is illuminated by mutually influential interactions of cosmological and quantum-level theories, practices, and pedagogy. workers in cultural heritage institutions and technologists pursuing w3c initiatives would do well to reflect on the result. ■■ ready for the future—and creating the future to explore the cultural, scientific, and mathematical ideas underlying cultural heritage resource description, to identify, study, and teach with exemplars, and to exploit the theoretical reach and bookkeeping capability of paper tool

are potential candidates for duplication. the problem which we faced at sussex university was how to obtain reliable forecasts of the demand for each title and to translate this into a purchasing policy. at present sussex spends between £10,000 and £20,000 ($22,00o-$44,000) per year on duplicate copies, and as the university grows this amount is increasing steadily. because of the large number of books in a library relatively little data are available about each title. records are kept of books on loan or removed from the library, but frequently these are the only routine data collected. few large libraries even manage inventory checks. we therefore looked for a system that could be implemented with the minimum of data collection, preferably one based on existing records. forecasts of demand if the demand for a particular book is known, it is possible, though not necessarily easy, to determine how many copies of that book are needed to achieve a specified level of service, such as a copy being available on 80 percent of the occasions that a reader requires the book. unfortunately demand cannot be measured directly, even retrospectively. records of the 74 journal of librm·y automation vol. 7/2 june 1974 number of times that a book is issued from the library contain no information about how many times the book was used within the library, nor how many readers failed to find a copy and went away unsatisfied. since both these factors are extremely difficult to measure, one of the central parts of our work was to develop a method of estimating them from data readily available. to forecast demand two lines of approach seemed reasonable: subjective estimation based on faculty reading lists; and forecasts based on the number of loans in previous years. in the past, sussex library has made extensive use of reading lists provided by faculty to decide how many copies to buy of each title. as the books most in demand are those recommended for undergraduate courses this seemed a sensible approach, though the number of copies required is not obvious even if the demand is known. webster analysed the effectiveness of these lists in predicting demand for specific titles and evaluated the purchasing rule being used, one copy for every ten students taking a course. 1 restricting his attention to books known to be in demand and marked in the catalog, he drew a random sample of 673 titles, about 4 percent of the books falling into this category. he compared the number of loans of each of these titles over a term· with data from the reading lists supplied at the beginning of the term. as the library had made a special effort to obtain reading lists for all courses taught that term, he had data on the number and type of students taking each course, the importance given to each text, and the subject areas involved. yet despite a thorough analysis of these data webster was able to find very little relationship between observed demand and reading list information. his work shows that faculty at the university have remarkably little knowledge of the books that their students read. in the sample some books strongly recommended to large groups of students were hardly used and some of the most heavily used works appeared on no reading list. the results of this study are fascinating from an educational viewpoint but less satisfying as operational research. the failure of this .. approach led us to predicting demand from records of the number of past loans. this divides into two parts: using the number of loans over a period to estimate what the total demand was during that period; and using this estimate of the demand in one period to forecast the demand in another. various evidence suggests that the latter is a sensible thing to do. the main demand for heavily used books comes from undergraduate courses. most faculty are loyal in their reading habits, recommending books they know rather than new ones, and each course tends to be repeated year after year with a syllabus that changes only gradually. the use of past circulation to forecast future use is fundamental to a markov model of book usage developed by morse and elston and tested with data from the m.i.t. engineering library. 2 for our work we have used the number of loans in a given term to predict the demand in the corresponding term a year later. simulation m odelj arms and walter 75 estimating the total demand in a period from the number of loans in that period is more difficult. this requires a model of the circulation system. mathematical approach several attempts have been made to apply the methods of inventory control or queueing theory to the problem of buying duplicates. for example, grant has recently described an operational system using the simple rule that the number of copies required to satisfy 95 percent of the demand is n (p,. + 2cr.)/t where n is the number of times that the book is issued during a period of t days and p,8 and cr8 are the mean and standard deviation of the time that each book is off the shelf when on loan. 3 this type of approach has the advantage of being straightforward to use. periodically a simple computer program analyzes the circulation history of each book in the library and prints a list of books requiring duplication. however, the method suffers from difficulties both mathematical and practical. to obtain the simple mathematical expression given above, several simplifying assumptions have to be made. for example, the expression ignores use of a book within the library, and identifies demand in a period with the number of loans within that period. practical difficulties in arriving at a more exact mathematical expression are discussed in the next section. difficulties in constructing a model the following are the main difficulties that we found in constructing a model, either mathematical or using simulation: 1. the most useful measure of the effectiveness of a duplication policy is satisfaction level, the proportion of readers who on approaching the shelves find a copy of the book there, but satisfaction level is almost impossible to measure directly since, although some unsatisfied readers ask that the book be held for them, most go away without comment. more or less equivalent is the percentage time on shelf, the proportion of time that at least one copy of the book is available. this can be measured directly, though a visit to the shelves is needed, and was found useful in validating our model. if the underlying demand is random these two measures of effectiveness have the same value. 2. use of books within the library is also difficult to measure. at sussex, as in most libraries, data are available only on the number of times that a book is lent out of the library. if a reader does not find a copy on the shelves or if he uses a book within the library but does not take it away then no record is generated. since various studies, notably that of fussier and simon, suggest that the amount of use within li76 ]oumal of libmry automation vol. 7/2 june 1974 braries often exceeds the number of loans recorded by a factor of three or more, if the number of loans is used to estimate demand a reasonable knowledge of within-library use is essential.4 3. the number of copies required to achieve a specified satisfaction level does not go up linearly with demand. since a reader is satisfied if he finds a single copy on the shelves, proportionately fewer duplicates are needed of the books most in demand. at sussex more than twenty copies are provided of several books and this nonlinearity is very noticeable. 4. the demand for a title is erratic, changing from term to term, from week to week, and from day to day, even if the mean demand is constant. over a period such as a term three different effects might be expected: a background random demand independent of university courses; sudden peaks when a book is required for a course taken by several students; and feedback caused by previously unsatisfied readers returning. 5. the circulation of books is surprisingly complicated. at sussex some books are designated short term loan and can be borrowed for up to four days only; the remainder are long term loan books and can be borrowed for up to six weeks. circulation data show that the time for which a book is off the shelf is not the same as the period for which it is lent, but has a heavily skewed distribution. few books are returned until near the due date; just before the book is due back there is a peak when most books are returned but many become overdue and the tail of the distribution dies away slowly. simulation as these various factors seemed too complex to derive usable mathematical results, we decided to use computer simulation of the book circulation. simulation of book circulation is not new. in particular it has been used at lancaster university by mackenzie et al. to decide loan periods.5 their report includes a good description of the general approach. the object of our simulation was to model the circulation process so that we could study the relationship between three groups of parameters: 1. 0 bserved data number of copies available number of loans 2. total underlying demand 3. measures of effectiveness satisfaction of level percentage time on shelf. the results obtained from any simulation are only as accurate as the values given to the variables used to calibrate the model. as several of these values were not known at all accurately when the work was begun, special efforts were put into careful validation and calibration of the mod76 ]oumal of libmry automation vol. 7/2 june 1974 braries often exceeds the number of loans recorded by a factor of three or

decided to use computer simulation of the book circulation. simulation of book circulation is not new. in particular it has been used at lancaster university by mackenzie et al. to decide loan periods.5 their report includes a good description of the general approach. the object of our simulation was to model the circulation process so that we could study the relationship between three groups of parameters: 1. 0 bserved data number of copies available number of loans 2. total underlying demand 3. measures of effectiveness satisfaction of level percentage time on shelf. the results obtained from any simulation are only as accurate as the values given to the variables used to calibrate the model. as several of these values were not known at all accurately when the work was begun, special efforts were put into careful validation and calibration of the modsimulation model/ arms and walter 77 el. a separate study was made for a small sample of books, to compare the percentage time on shelf estimated by the simulation with the actual time for which a copy was available, found by looking at the shelves. the results of this study were used to check the amount of use within the library. by this means we were able to verify the simulation model and calibrate it to a highly satisfactory level of accuracy. description of program the basic layout of the simulation is shown in figure 1. .this is a time advance model with a period of one day. the program has been coded in fortran and running on the icl 1904a computer at sussex takes about one second of machine time to simulate two years. this fast speed has enabled us to try a wide range of values for most parameters and to experiment with a variety of distributions of arrival times and book return dates. 1. satisfaction level at the beginning of each day the number of demands for that day is generated. the satisfaction level is taken as the proportion of these requests which can be satisfied from the books left on the shelf from the previous day and those returned during the simulated day. 2. within-library use the proportion of use that takes place within the library was a key parameter in calibrating the model. the first version of the simulation program assumed a figure of 25 percent use within the library. this was based on a small survey of the type of books being studied, standard texts used for undergraduate courses. the weakness of this survey was that it used a count of those books that were left lying in the library at the end of the day and did not make sufficient allowance for books reshelved by readers or by library staff during the day. the validation experiment showed a consistent difference between predicted and observed percentage time on shelf which could be corrected by changing the value of the within-library use parameter to 60 percent. 3. distribution of demand two distributions of demand have been used, poisson arrivals with a specified mean, and a step demand superimposed on a poisson process. in both cases provision is made for a proportion of unsatisfied readers to return later. as the effect of this feedback is to introduce sharp peaks of demand, the two distributions have proved surprisingly similar in the results produced and most of the runs of the program have been done with random demand. a recent survey showed that 69 percent of readers who fail to find a book intend to return, but we do not know how many actually come back nor what the time interval is before they return. 6 the simulation proved to be insensitive to moderate changes of these parameters 78 journal of library automation vol. 7/2 june 1974 advance clock one day add returned books generate requests fig. 1. outline flowchart of simulation program generate :return date generate return date reader return date simulation model/ arms and walter 79 and for most runs 25 percent of unsatisfied readers were deemed to return after a delay which averaged two days. 4. period for which the book is off the shelf the simulation allows for a book to be borrowed within the library, in which case it is available again the next day, or to be lent from the library. if the book is lent, the return date is generated from one of two histograms which respectively refer to books available on short and long term loan. these histograms were derived from an analysis of all books returned during one week in autumn 1970, modified to reflect changes in the circulation system. validation experiment although the structure of the simulation is fairly straightforward several parameters used in the model have been estimated indirectly. validation of the model took two forms. firstly we ran the program with a wide range of values for the main parameters to see which most influence the results. secondly a small study was set up to measure the percentage time on shelf of a number of books. for each book, the actual availability was estimated by the simulation from the number of loans during the same period. twenty-eight books known to be in heavy demand were selected, half in physics and half in sociology. over a period of eight weeks the shelves were inspected once per day, at random times during the day, to see if a copy was available. the number of loans of each copy of each book during the period was noted and the library staff carried out a thorough check to determine whether any copies shown in the catalog had been lost, stolen, or had their loan category altered. the simulation was used to estimate the percentage time on shelf and this was plotted on a graph against the observed percentage. figure 2 shows the graph for the original values of the parameters. in this graph the x axis shows the percentage time on shelf predicted by the simulation; the y axis shows the percentage observed. if the model were perfect the points would lie near the line y = x, deviations being caused by y being a random variable. the graph in figure 2 is clearly convex downwards showing a consistent error in the model, with these values of the parameters. knowing that the simulation is sensitive to the parameter giving the proportion of use that takes place within the library and that our estimate of its value was not precise, a series of graphs were prepared varying this parameter. figure 3 shows the same observations plotted against predictions assuming 60 percent use within the library, the value which best predicts the observations. this graph is much closer to being linear than figure2. the next question is whether the nonlinearities in figure 3 are the type to be expected from y being a random variable. a very rough calculation helps to answer this question. if we make the dubious assumption that 80 i

time on shelf) fig. 2. observed percentage time on shelf against predicted ( 25 percent use within library) availability of a copy on a given day is independent of the days before and afterwards, then, for x given, y should be approximately normally distributed with mean x and variance x( 1 : ) , where n is the number of days in the study (forty). if this calculation were exact, 95 percent of the observations of y would lie within two standard deviations of x, but, since the assumption of independence is definitely false, we would expect the number of observations which fall within the range to be less than 95 percent. the curves y = x ± 2 { x(lx)/n} ¥. observed availability (percent time on shelf) 100 75 50 25 simulation model/ arms and walter 81 predicted availability (percent time on shelf) fig. 3. observed percentage time on shelf against predicted ( 60 percent use within library) with 95 percent probability curves have been added to figure 3. two points lie well off all graphs and cannot be explained except as the result of books being stolen or lost during the period of the study. of the remaining twenty-six all but three lie within the curves. this shows that the simulation model as finally calibrated gives a very reasonable description of the situation. operational experience the results of this simulation have been used by library staff since the middle of 1971 initially on an experimental basis. a two-stage process is in82 journal of library automation vol. 7/2 june 1974 volved. from the computer based circulation system cau; be found the number of times that each short term loan copy has been circulated. from these figures the library staff can estimate the demand for a title, over a given period. once the demand has been estimated the staff can use the simulation again to determine how many copies would have been required to have achieved a specified satisfaction level, perhaps 80 percent. if fewer copies are held by the library orders are placed for extra copies. at present these procedures are done manually using tables, but the possibility exists of modifying the computer system to identify those titles which need extra duplication. the actual decision to purchase needs to be done by library staff who can take account of factors not included in the simulation, such as price and changes of undergraduate courses. conclusion although this work was carried out during 1971, we shall have little operational experience of the method in action until the computer circulation system is reorganized. in the past, different copies of the same book have been processed entirely independently, meaning that the total number of loans of a given title can only be found by manually adding up the number of loans of each copy. in the revised computer system this will be done automatically. experience will probably show that the best procedure combines use of the simulation model with reading lists and the skill of a librarian. one possible feature of a computer based system is that it could automatically indicate which books appear to require duplication. the method used here would seem to apply equally well to other libraries. naturally the circulation patterns of other libraries are different, which means that a different simulation would be needed, but this work has shown that it is possible to calibrate a simulation accurately enough to examine the circulation of individual books. acknowledgments we would like to thank the many members of the university of sussex library staff who have

information technology and libraries | june 2014 1 at my home institution, johns hopkins, we have a renowned professor who made a keen insight several years ago. dr. peter pronovost, professor of anesthesiology and critical care medicine, of public health policy and management, of surgery, and of nursing, took note of the fact that many careless errors were occurring in hospital intensive care units, errors that were due not to ignorance, but to overlooking simple, mundane pr ocesses and procedures that maximize the safety of patients and increase the likelihood of positive medical outcomes. how to remedy this situation? as is often the case, the simplest solution is the most profound, the most effective, the most brilliant. pronovost implemented straightforward checklists of processes and procedures for doctors and nurses to routinely follow in the intensive care unit (icu). there was nothing on these checklists the medical staff did not already know; indeed, they were so basic that what was listed almost went without saying. but the brilliance of pronovost’s insight was that the very implementation of a “just saying” checklist resulted in an immediate and significant improvement in patient outcomes. so simple. so easily done. might we here in the library it world implement just such a checklist? in particular, i’m wondering whether we might begin to construct a fairly comprehensive checklist of what i’m calling “software genres” for use in libraries. it doesn’t take much insight to see that software packages map to services and that groups of these packages cluster around such services. such clusters, i’m thinking, are actually genres of software. so, for instance, let’s think about a standard libr ary service: a service that fulfills the need of academic institutions to store, archive, and provide access to faculty research. we see software systems emerge to fulfil this need, e.g., dspace, contentdm, fedora, eprints, and islandora. we can think of each of these systems as the fulfilment of similar sets of requirements and these requirements as being dictated by the satisfaction of a need. these systems individually represent concrete instantiations of clusters of similar requirements. but these systems also cluster among and between themselves insofar as the requirements and the needs they satisfy are similar. they form a genre of software. now, we’ve identified one genre of software useful in libraries: institutional repository software. what other genres might there be? how about the granddaddy of them all: a software mark cyzyk (mcyzyk@jhu.edu), a member of the ital editorial board, is the scholarly communication architect in the sheridan libraries, john hopkins univ ersity, baltimore, maryland. mailto:mcyzyk@jhu.edu editorial board thoughts: the checklist | cyzyk 2 system/concrete-instantiation-of-requirements fulfilling the need in libraries to enable the creation and collection of bibliographic metadata, to provide access to that metadata to library patrons, to enable the management of the circulation of physical and electronic objects mapping to that metadata and to manage acquisition of materials including serial publications? why it’s the venerable integrated library management system, of course! and here we’ll find such open-source examples as koha and evergreen alongside their commercial counterparts. continuing to compile, we’ll begin to gather a table of data similar to what’s below. but what good is this? don’t we all already know about these software “genres”? aren’t we just in some sense stating the obvious? to the extent that these software genres and the software packages classified by each are obvious, this table, this checklist, resembles the checklists that professor pronovost presented to doctors and nurses in the icu. those doctors and nurses certainly knew to wash their hands, to properly sterilize around an area of catheterization, etc. and if they were about to overlook a hand-washing or sterilization, the checklist brought this need and requirement immediately to their attention. so too we might be aware of, say, the fact that many libraries implement systems to manage visual resources, electronic images. we may work in a library that does not. yet scanning the list below we’ll see that it is a need with requirements that cluster to such an extent that a genre has developed around it. we may say to ourselves, “we too have a significant collection of electronic images that we’ve just been putting into our local repository, but maybe the repository is not the right place for this content, maybe we should look into these other systems designed specifically for storing and serving up images?” more, suppose you work in a really small and r esourceconstrained library, yet one that has an important archival collection of materials related to local history? you now scan the table below and determine that there is indeed a genre of archival information systems. “maybe we should set up an instance of archivesspace to facilitate the cataloging and provision of access to our archival treasures?” maybe you should! now some of these systems can do double duty. dspace, for instance, could be used as a serviceable image management/data management/etd management system. but cramming so many disparate kinds of content into a single system and expecting it to behave like a bona fide image management or data management or etd management system is probably a bad idea. the whole reason these genres emerge in the first place is that they satisfy the idiosyncratic needs of various types of content; their functionalities are tailored to the types of services one would want to provide surrounding such disparate types of content. using the right tool for the job is surely a best practice if ever there was one. that said, some of these software packages, by design, cut across the different genres in much the same way that, say, the music of ryan adams cuts across the genres of rock and alt country or the novels of china mieville cut across all manner of literary genres. islandora provides a good example of this. it can be used as a repository, but its various “solution packs” allow it to be information technology and libraries | june 2014 3 expanded to serve well as, for example, an image management system. islandora, interestingly, is itself built on two of the software packages listed below—drupal and fedora—combining the strengths and functionalities of both, resulting in a genre -busting (genre-extending?) software package. viewing software packages as types of genres is useful insofar as, when it comes time to assemble requirements for a new project or ser vice, thinking of existing software systems as concrete instantiations of such requirements speeds the accomplishment of this task. rather than begin to gather requirements ex nihilo, we should be thinking, “here are some prime examples of actual working systems that fulfil the satisfaction of needs similar to ours. how about we compile a list of them, install a few, and see what they do? maybe there is something here that fits our specific need?” so simple. so easily done. check! software genre software packages ilms koha evergreen aleph millennium polaris symphony horizon voyager indexing and discovery blacklight summon worldcat local

 an  indispensable  tool  for  library  users,  even  if  it  may  be  used  only   at  a  later  stage  in  the  research  process.   at  the  university  of  north  carolina  at  chapel  hill,  we  have  continued  to  invest  in  enhancing  the   utility  of  the  catalog  as  a  valued  tool  for  research.  librarians  initially  reasoned  that  researchers   still  want  to  find  out  what  is  available  to  them  in  their  own  campus  library.  gradually  they  began   to  see  completely  new  possibilities.  to  that  end,  we  have  committed  to  a  program  that  enhances   discovery  and  delivery  through  the  catalog.  while  most  libraries  have  built  a  wide  range  of   discovery  tools  into  their  home  pages—adding  links  to  databases  of  electronic  resources,  article   databases,  and  google  scholar—we  have  continued  to  enhance  both  the  content  to  be  found  in  the   primary  local  bibliographic  database  and  the  services  available  to  students  and  researchers  via  the   interface  to  the  catalog.   in  our  local  consortium,  the  triangle  research  libraries  network  (trln),  librarians  have   deployed  the  search  and  faceting  services  of  endeca  to  enrich  the  discovery  interfaces.  we  have   gone  beyond  augmenting  the  catalog  through  the  addition  of  marcive  records  for  government   documents,  by  including  encoded  archival  description  (ead)  finding  aids  and  selected  (and  ever-­‐ expanding)  digital  collections  that  are  not  easily  discoverable  through  major  search  engines.  we   have  similarly  enhanced  services  related  to  the  discovery  and  delivery  of  items  listed  in  the   bibliographic  database,  including  not  only  common  features  like  the  ability  to  export  citations  in  a   variety  of  formats  but  also  more  extensive  services  such  as  document  delivery,  an  auto-­‐suggest   feature  that  maximizes  use  of  library  of  congress  subject  headings  (lcsh),  and  the  ability  to   submit  cataloged  items  to  be  processed  for  reserve  reading.     information  technology  and  libraries  |  june  2015     7   both  students  and  faculty  have  embraced  e-­‐books,  and  in  adding  more  than  a  million  such  titles  to   the  unc-­‐chapel  hill  catalog  we  continue  to  blend  discovery  and  delivery,  but  now  on  a  very  large   scale.  coupling  catalog  records  with  a  metadata  service  that  provides  book  jackets,  tables  of   contents,  and  content  summaries,  cataloging  geographic  information  systems  (gis)  data  sets,  and   adding  live  links  to  the  finding  aids  for  digitized  archival  and  manuscript  collections  have  further   enhanced  the  blended  discovery/delivery  capacity  of  the  catalog.   we  have  also  leveraged  the  advantages  of  operating  in  a  consortial  environment  by  extending  the   discovery  and  delivery  services  among  the  members  of  trln  to  provide  increased  scope  of   discovery  and  shared  processing  of  some  classes  of  bibliographic  records.  trln  comprises  four   institutions  and  content  from  all  member  libraries  is  discoverable  in  a  combined  catalog   (http://search.trln.org).  printed  material  requested  through  this  combined  catalog  is  often   delivered  between  trln  libraries  within  twenty-­‐four  hours.   at  unc,  our  search  logs  show  that  use  of  the  catalog  increases  as  we  add  new  capacity  and  content.   these  statistics  demonstrate  the  catalog’s  continuing  relevance  as  a  research  tool  that  adds  value   above  and  beyond  conventional  search  engines  and  general  web-­‐based  information  resources.  in   this  article  we  will  describe  the  most  important  enhancements  to  our  catalog,  include  data  from   search  logs  to  demonstrate  usage  changes  resulting  from  these  enhancements,  and  comment  on   potential  future  developments.   literature  review   an  extensive  literature  discusses  the  past  and  future  of  online  catalogs,  and  many  of  these   materials  themselves  include  detailed  literature  reviews.  in  fact,  there  are  so  many  studies,   reviews,  and  editorials,  it  becomes  clear  that  although  the  online  catalog  may  be  in  decline,  it   remains  a  subject  of  lively  interest  to  librarians.  two  important  threads  in  this  literature  report  on   user-­‐query  studies  and  on  other  usability  testing.  though  there  are  many  earlier  studies,  two   relatively  recent  articles  analyze  search  behavior  and  provide  selective  but  helpful  literature   surveys.5     there  are  many  efforts  to  define  directions  for  the  catalog  that  would  make  it  more  web-­‐like,  more   google-­‐like,  and  thus  more  often  chosen  for  search,  discovery,  and  access  by  library  patrons.   these  articles  aim  to  define  the  characteristics  of  the  ideal  catalog.  charles  hildreth  provides  a   benchmark  for  these  efforts  by  dividing  the  history  of  the  online  catalog  into  three  generations.   from  his  projections  of  a  third  generation  grew  the  “next  generation  catalog”—really  the  current   ideal.  he  called  for  improvement  of  the  second-­‐generation  catalog  through  an  enhanced  user-­‐ system  dialog,  automatic  correction  of  search-­‐term  spelling  and  format  errors,  automatic  search   aids,  enriched  subject  metadata  in  the  catalog  record  to  improve  search  results,  and  the   integration  of  periodical  indexes  in  the  catalog.  as  new  technologies  have  made  it  possible  to   achieve  these  goals  in  new  ways,  much  of  what  hildreth  envisioned  has  been  accomplished.6       engine  of  innovation:  building  the  high-­‐performance  catalog  |  owen  and  michalak       doi:  10.6017/ital.v34i2.5702   8   second-­‐generation  catalogs,  anchored  firmly  in  integrated  library  systems,  operated  throughout   most  of  the  1980s  and  the  1990s  without  significant  improvement.  by  the  mid-­‐2000s  the  search   for  the  “next-­‐gen”  catalog  was  in  full  swing,  and  there  are  numerous  articles  that  articulate  the   components  of  an  improved  model.  the  catalog  crossed  a  generational  line  for  good  when  the   north  carolina  state  university  libraries  (ncsu)  launched  a  new  catalog  search  engine  and   interface  with  endeca  in  january  2006.  three  ncsu  authors  published  a  thorough  article   describing  key  catalog  improvements.  their  endeca-­‐enhanced  catalog  fulfilled  the  most  important   criteria  for  a  “next-­‐gen”  catalog:  improved  search  and  retrieval  through  “relevance-­‐ranked  results,   new  browse  capabilities,  and  improved  subject  access.”7     librarians  gradually  concluded  that  the  catalog  need  not  be  written  off  but  would  benefit  from   being  enhanced  and  aligned  with  search  engine  capabilities  and  other  web-­‐like  characteristics.   catalogs  should  contain  more  information  about  titles,  such  as  book  jackets  or  reviews,  than   conventional  bibliographic  records  offered.  catalog  search  should  be  understandable  and  easy  to   use.  additional  relevant  works  should  be  presented  to  the  user  along  with  result  sets.  the   experience  should  be  interactive  and  participatory  and  provide  access  to  a  broad  array  of   resources  such  as  data  and  other  nonbook  content.8     karen  markey,  one  of  the  most  prolific  online  catalog  authors  and  analysts,  writes,  “now  that  the   era  of  mass  digitization  has  begun,  we  have  a  second  chance  at  redesigning  the  online  library   catalog,  getting  it  right,  coaxing  back  old  users  and  attracting  new  ones.”9   marshall  breeding  predicted  characteristics  of  the  next-­‐generation  catalog.  his  list  includes   expanded  scope  of  search,  more  modern  interface  techniques,  such  as  a  single  point  of  entry,   search  result  ranking,  faceted  navigation,  and  “did  you  mean  .  .  .  ?”  capacity,  as  well  as  an  expanded   search  universe  that  includes  the  full  text  of  journal  articles  and  an  array  of  digitized  resources.10     a  concept  that  is  less  represented  in  the  literature  is  that  of  envisioning  the  catalog  as  a   framework  for  service,  although  the  idea  of  the  catalog  designed  to  ensure  customer  self-­‐service   has  been  raised.11  michael  j.  bennett  has  studied  the  effect  of  catalog  enhancements  on  circulation   and  interlibrary  loan.12  service  and  the  online  catalog  have  a  new  meaning  in  morgan’s  idea  of   “services  against  texts,”  supporting  “use  and  understand”  in  addition  to  the  traditional  “find  and   get.”13  lorcan  dempsey  commented  on  the  catalog  as  an  identifiable  service  and  predicts  new   formulations  for  library  services  based  on  the  network-­‐level  orientation  of  search  and  discovery.14   but  the  idea  that  the  catalog  has  moved  from  a  fixed,  inward-­‐focused  tool  to  an  engine  for   services—a  locus  to  be  invested  with  everything  from  unmediated  circulation  renewal  and   ordering  delivery  to  the  “did  you  mean”  search  aid—has  yet  to  be  addressed  comprehensively  in   the  literature.   enhancing  the  traditional  catalog   one  of  the  factors  that  complicates  discussions  of  the  continued  relevance  of  the  library  catalog  to   research  is  the  very  imprecision  of  the  term  in  common  parlance,  especially  when  the  chief  point     information  technology  and  libraries  |  june  2015     9   of  comparison  to  today’s  ils-­‐driven  opacs  is  google  or,  more  specifically,  google  scholar.  from   first-­‐year  writing  assignments  through  advanced  faculty  research,  many  of  the  resources  that  our   patrons  seek  are  published  in  the  periodical  literature,  and  the  library  catalog,  the  one  descended   from  the  cabinets  full  of  cards  that  occupied  prominent  real  estate  in  our  buildings,  has  never  been   an  effective  tool  for  identifying  relevant  periodical  literature.   this  situation  has  changed  in  recent  years  as  products  like  summon,  from  proquest,  and  ebsco   discovery  service  have  introduced  platforms  that  can  accommodate  electronic  article  indexing  as   well  as  marc  records  for  the  types  of  materials—books,  audio,  and  video—that  have  long  been   discovered  through  the  opac.  in  the  following  discussion  of  “catalog”  developments  and   enhancements,  we  focus  initially  not  on  these  integrated  solutions,  but  on  the  catalog  as  more   traditionally  defined.  however,  as  electronic  resources  become  an  ever-­‐greater  percentage  of   library  collections,  we  shall  see  a  convergence  of  these  two  streams  that  will  portend  significant   changes  in  the  nature  and  utility  of  the  catalog.   much  work  has  been  done  in  the  first  decade  of  the  twenty-­‐first  century  to  enhance  discovery   services  and,  as  noted  above,  north  carolina  state  university’s  introduction  of  their  endeca-­‐based   search  engine  and  interface  was  a  significant  game-­‐changer.  in  the  years  following  the   introduction  of  the  endeca  interface  at  ncsu,  the  triangle  research  libraries  network  invested  in   further  development  of  features  that  enhanced  the  utility  of  the  endeca  software  itself.   programmed  enhancements  to  the  interface  provided  additional  services  and  functionality.  in   some  cases,  these  enhancements  were  aimed  at  improving  discovery.  in  others,  they  allowed   researchers  to  make  new  and  better  use  of  the  data  that  they  found  or  made  it  easier  to  obtain  the   documents  that  they  discovered.   faceting  and  limiting  retrieval  results   perhaps  the  most  immediately  striking  innovation  in  the  endeca  interface  was  the  introduction  of   facets.  the  use  of  faceted  browsing  allowed  users  to  parse  the  bibliographic  record  in  new  ways   (and  more  ways)  than  had  preceding  catalogs.  there  were  several  fundamentally  important  ways   faceting  enhanced  search  and  discovery.   the  first  of  these  was  the  formal  recognition  that  keyword  searching  was  the  user’s  default  means   of  interacting  with  the  catalog’s  data.  ncsu’s  initial  implementation  allowed  for  searches  using   several  indexes,  including  authors,  titles,  and  subject  headings,  and  this  functionality  remains  in   place  to  the  present  day.  however,  by  default,  searches  returned  records  containing  the  search   terms  “anywhere”  in  the  record.  this  behavior  was  more  in  line  with  user  expectations  in  an   information  ecosystem  dominated  by  google’s  single  search  box.   the  second  was  the  significantly  different  manner  in  which  multiple  limits  could  be  placed  on  an   initial  result  set  from  such  a  keyword  search.  the  concept  of  limiting  was  not  a  new  one:  certain   facets  worked  in  a  manner  consistent  with  traditional  limits  in  prior  search  interfaces,  allowing   users  to  screen  results  by  language,  or  date  of  publication,  for  example.       engine  of  innovation:  building  the  high-­‐performance  catalog  |  owen  and  michalak       doi:  10.6017/ital.v34i2.5702   10   it  was  the  ease  and  transparency  with  which  multiple  limits  could  be  applied  through  faceting  that   was  revolutionary.  a  user  who  entered  the  keyword  “java”  in  the  search  box  was  quickly  able  to   discriminate  between  the  programming  language  and  the  indonesian  island.  this  could  be   achieved  in  multiple  ways:  by  choosing  between  subjects  (for  example,  “application  software”  vs.   “history”)  or  clearly  labeled  lc  classification  categories  (“q  –  science”  vs.  “d  –  history”).  these   limits,  or  facets,  could  be  toggled  on  and  off,  independently  and  iteratively.   the  third  and  highly  significant  difference  resulted  from  how  library  of  congress  subject   headings  (lcsh)  were  parsed  and  indexed  in  the  system.  by  making  lcsh  subdivisions   independent  elements  of  the  subject-­‐heading  index  in  a  keyword  search,  the  endeca   implementation  unlocked  a  trove  of  metadata  that  had  been  painstakingly  curated  by  catalogers   for  nearly  a  century.  the  user  no  longer  needed  to  be  familiar  with  the  formal  structure  of  subject   headings;  if  the  keywords  appeared  anywhere  in  the  string,  the  subdivisions  in  which  they  were   contained  could  be  surfaced  and  used  as  facets  to  sharpen  the  focus  of  the  search.  this  was   revolutionary.   utilizing  the  power  of  new  indexing  structures   the  liberation  of  bibliographic  data  from  the  structure  of  marc  record  indexes  presaged  yet   another  far-­‐reaching  alteration  in  the  content  of  library  catalogs.  to  this  day,  most  commercial   integrated  library  systems  depend  on  marc  as  the  fundamental  record  structure.  in  ncsu’s   implementation,  the  multiple  indexes  built  from  that  metadata  created  a  new  framework  for   information.     this  change  made  possible  the  integration  of  non-­‐marc  data  with  marc  data,  allowing,  for   example,  dublin  core  (dc)  records  to  be  incorporated  into  the  universe  of  metadata  to  be  indexed,   searched,  and  retrieved.  there  was  no  need  to  crosswalk  dc  to  marc:  it  sufficed  to  simply  assign   the  dc  elements  to  the  appropriate  endeca  indexes.  with  this  capacity  to  integrate  rich  collections   of  locally  described  digital  resources,  the  scope  of  the  traditional  catalog  was  enlarged.   expanding  scopes  and  banishing  silos   at  unc-­‐chapel  hill,  we  began  this  process  of  augmentation  with  selected  collections  of  digital   objects.  these  collections  were  housed  in  a  contentdm  repository  we  had  been  building  for   several  years  at  the  time  of  the  library’s  introduction  of  the  endeca  interface.  image  files,  which   had  not  been  accessible  through  traditional  catalogs,  were  among  the  first  to  be  added.  for   example,  we  had  been  given  a  large  collection  of  illustrated  postcards  featuring  scenes  of  north   carolina  cities  and  towns.  these  postcards  had  been  digitized  and  metadata  describing  the  image   and  the  town  had  been  recorded.  other  collections  of  digitized  historical  photographs  were  also   selected  for  inclusion  in  the  catalog.  these  historical  resources  proved  to  be  a  boon  to  faculty   teaching  local  history  courses  and,  interestingly,  to  students  working  on  digital  projects  for  their   classes.  as  class  assignments  came  to  include  activities  like  creating  maps  enhanced  by  the     information  technology  and  libraries  |  june  2015     11   addition  of  digital  photographs  or  digitized  newspaper  clippings,  the  easy  discovery  of  these   formerly  hidden  collections  enriched  students’  learning  experience.   other  special  collection  materials  had  been  represented  in  the  traditional  catalog  in  somewhat   limited  fashion.  the  most  common  examples  were  manuscripts  collections.  the  processing  of   these  collections  had  always  resulted  in  the  creation  of  finding  aids,  produced  since  the  1930s   using  index  cards  and  typewriters.  during  the  last  years  of  the  twentieth  century,  archivists  began   migrating  many  of  these  finding  aids  to  the  web  using  the  ead  format,  presenting  them  as  simple   html  pages.  these  finding  aids  were  accessible  through  the  catalog  by  means  of  generalized   marc  records  that  described  the  collections  at  a  superficial  level.  however,  once  we  attained  the   ability  to  integrate  the  contents  of  the  finding  aids  themselves  into  the  indexes  underlying  the  new   interface,  this  much  richer  trove  of  keyword-­‐searchable  data  vastly  increased  the  discoverability   and  use  of  these  collections.   during  this  period,  the  library  also  undertook  systematic  digitization  of  many  of  these  manuscript   collections.  whenever  staff  received  a  request  for  duplication  of  an  item  from  a  manuscript   collection  (formerly  photocopies,  but  by  then  primarily  digital  copies),  we  digitized  the  entire   folder  in  which  that  item  was  housed.  we  developed  standards  for  naming  these  digital  surrogates   that  associated  the  individual  image  with  the  finding  aid.  it  then  became  a  simple  matter,  involving   the  addition  of  a  short  javascript  string  to  the  head  of  the  online  finding  aid,  to  dynamically  link   the  digital  objects  to  the  finding  aid  itself.     other  library  collections  likewise  benefited  from  the  new  indexing  structures.  some  uncataloged   materials  traditionally  had  minimal  bibliographic  control  provided  by  inventories  that  were  built   at  the  time  of  accession  in  desktop  database  applications;  funding  constraints  meant  that  full   cataloging  of  these  materials  (often  rare  books)  remained  elusive.  the  ability  to  take  the  data  that   we  had  and  blend  it  into  the  catalog  enhanced  the  discovery  of  these  collections  as  well.   we  also  have  an  extensive  collection  of  video  resources,  including  commercial  and  educational   films.  the  conventions  for  cataloging  these  materials,  held  over  from  the  days  of  catalog  cards,   often  did  not  match  user  expectations  for  search  and  discovery.  there  were  limits  to  the  number   of  added  entries  that  catalogers  would  make  for  directors,  actors,  and  others  associated  with  a   film.  many  records  lacked  the  kind  of  genre  descriptors  that  undergraduates  were  likely  to  use   when  seeking  a  film  for  an  evening’s  entertainment.  to  compensate  for  these  limitations,  staff  who   managed  the  collection  had  again  developed  local  database  applications  that  allowed  for  the   inclusion  of  more  extensive  metadata  and  for  categories  such  as  country  of  origin  or  folksonomic   genres  that  patrons  frequently  indicated  were  desirable  access  points.  once  again,  the  new   indexing  structures  allowed  us  to  incorporate  this  rich  set  of  metadata  into  what  looked  like  the   traditional  catalog.   each  of  the  instances  described  above  represents  what  we  commonly  call  the  destruction  of  silos.   information  about  library  collections  that  had  been  scattered  in  numerous  locations—and  not  all   of  them  online—was  integrated  into  a  single  point  of  discovery.  it  was  our  hope  and  intention  that     engine  of  innovation:  building  the  high-­‐performance  catalog  |  owen  and  michalak       doi:  10.6017/ital.v34i2.5702   12   such  integration  would  drive  more  users  to  the  catalog  as  a  discovery  tool  for  the  library’s  diverse   collections  and  not  simply  for  the  traditional  monographic  and  serials  collections  that  had  been   served  by  marc  cataloging.  usage  logs  indicate  that  the  average  number  of  searches  conducted  in   the  catalog  rose  from  approximately  13,000  per  day  in  2009  to  around  19,000  per  day  in  2013.  it   is  impossible  to  tell  with  any  certainty  whether  there  was  heavier  use  of  the  catalog  simply   because  increasingly  varied  resources  came  to  be  represented  in  it,  but  we  firmly  believe  that  the   experience  of  users  who  search  for  material  in  our  catalog  has  become  much  richer  as  a  result  of   these  changes  to  its  structure  and  content.   cooperation  encouraging  creativity   another  way  we  were  able  to  harness  the  power  of  endeca’s  indexing  scheme  involved  the  shared   loading  of  bibliographic  records  for  electronic  resources  to  which  multiple  trln  libraries   provided  access.  trln’s  endeca  indexes  are  built  from  the  records  of  each  member.  each   institution  has  a  “pipeline”  that  feeds  metadata  into  the  combined  trln  index.  duplicate  records   are  rolled  up  into  a  single  display  via  oclc  control  numbers  whenever  possible,  and  the   bibliographic  record  is  annotated  with  holdings  statements  for  the  appropriate  libraries.   we  quickly  realized  that  where  any  of  the  four  institutions  shared  electronic  access  to  materials,  it   was  redundant  to  load  copies  of  each  record  into  the  local  databases  of  each  institution.15  instead,   one  institution  could  take  responsibility  for  a  set  of  records  representing  shared  resources.   examples  of  such  material  include  electronic  government  documents  with  records  provided  by   the  marcive  documents  without  shelves  program,  large  sets  like  early  english  books  online,  and   pbs  videos  streamed  by  the  statewide  services  of  nc  live.   in  practice,  one  institution  takes  responsibility  for  loading,  editing,  and  performing  authority   control  on  a  given  set  of  records.  (for  example,  unc,  as  the  regional  depository,  manages  the   documents  without  shelves  record  set.)  these  records  are  loaded  with  a  special  flag  indicating   that  they  are  part  of  the  shared  records  program.  this  flag  generates  a  holdings  statement  that   reflects  the  availability  of  the  electronic  item  at  each  institution.  the  individual  holdings   statements  contain  the  institution-­‐specific  proxy  server  information  to  enable  and  expedite  access.   in  addition  to  this  distributed  model  of  record  loading  and  maintenance,  we  were  able  to  leverage   oai-­‐pmh  feeds  to  add  selected  resources  to  the  searchtrln  database.  all  four  institutions  have   access  to  the  data  made  available  by  the  inter-­‐university  consortium  for  political  and  social   research  (icpsr).  as  we  do  not  license  these  resources  or  maintain  them  locally,  and  as  records   provided  by  icpsr  can  change  over  time,  we  developed  a  mechanism  to  harvest  the  metadata  and   push  it  through  a  pipeline  directly  into  the  searchtrln  indexes.  none  of  the  member  libraries’   local  databases  house  this  metadata,  but  the  records  are  made  available  to  all  nonetheless.   while  we  were  engaged  in  implementing  these  enhancements,  additional  sources  of  potential   enrichment  of  the  catalog  were  appearing.  in  particular,  vendors  began  providing  indexing   services  for  the  vast  quantities  of  electronic  resources  contained  in  aggregator  databases.     information  technology  and  libraries  |  june  2015     13   additionally,  they  made  it  possible  for  patrons  to  move  seamlessly  from  the  catalog  to  those   electronic  resources  via  openurl  technologies.  indeed,  services  like  proquest’s  summon  or   ebsco’s  discovery  service  might  be  taken  as  another  step  toward  challenging  the  catalog’s   primacy  as  a  discovery  tool  as  they  offered  the  prospect  of  making  local  catalog  records  just  a   fraction  of  a  much  larger  universe  of  bibliographic  information  available  in  a  single,  keyword-­‐ searchable  database.   it  remains  to  be  seen,  therefore,  whether  continuing  to  load  many  kinds  of  marc  records  into  the   local  database  is  an  effective  aid  to  discovery  even  with  the  multiple  delimiting  capabilities  that   endeca  provides.  what  is  certain,  however,  is  that  our  approach  to  indexing  resources  of  any  kind   has  undergone  a  radical  transformation  over  the  past  few  years—a  transformation  that  goes   beyond  the  introduction  of  any  of  the  particular  changes  we  have  discussed  so  far.   promoting  a  culture  of  innovation   one  important  way  endeca  has  changed  our  libraries  is  that  a  culture  of  constant  innovation  has   become  the  norm,  rather  than  the  exception,  for  our  catalog  interface  and  content.  once  we  were   no  longer  subject  to  the  customary  cycle  of  submitting  enhancement  requests  to  an  integrated   library  system  vendor,  hoping  that  fellow  customers  shared  similar  desires,  and  waiting  for  a   response  and,  if  we  were  lucky,  implementation,  we  were  able  to  take  control  of  our  aspirations.   we  had  the  future  of  the  interface  to  our  collections  in  our  own  hands,  and  within  a  few  years  of   the  introduction  of  endeca  by  ncsu,  we  were  routinely  adding  new  features  to  enhance  its   functionality.   one  of  the  first  of  these  enhancements  was  the  addition  of  a  “type-­‐ahead”  or  “auto-­‐suggest”   option.16  inspired  by  google’s  autocomplete  feature,  this  service  suggests  phrases  that  might   match  the  keywords  a  patron  is  typing  into  the  search  box.  ben  pennell,  one  of  the  chief   programmers  working  on  endeca  enhancement  at  unc-­‐chapel  hill,  built  a  solr  index  from  the  ils   author,  title,  and  subject  indexes  and  from  a  log  of  recent  searches.  as  a  patron  typed,  a  drop-­‐ down  box  appeared  below  the  search  box.  the  drop-­‐down  contained  matching  terms  extracted   from  the  solr  index  in  a  matter  of  seconds  or  less.  for  example,  typing  the  letters  “bein”  into  the   box  produced  a  list  including  “being  john  malkovich,”  “nature—effects  of  human  beings  on,”   “human  beings,”  and  “bein,  alex,  1903–1988.”  the  italicized  letters  in  these  examples  are   highlighted  in  a  different  color  in  the  drop-­‐down  display.  in  the  case  of  terms  drawn  directly  from   an  index,  the  index  name  appears,  also  highlighted,  on  the  right  side  of  the  box.  for  example,  the   second  and  third  terms  in  the  examples  above  are  tagged  with  the  term  “subject.”  the  last  example   is  an  “author.”   in  allowing  for  the  textual  mining  of  lcsh,  the  initial  implementation  of  faceting  in  the  endeca   catalog  surfaced  those  headings  for  the  patron  by  uniting  keyword  and  controlled  vocabularies  in   an  unprecedented  manner.  there  was  a  remarkable  and  almost  immediate  increase  in  the  number   of  authority  index  searches  entered  into  the  system.  at  the  end  of  the  fall  semester  prior  to  the   implementation  of  the  auto-­‐suggest  feature,  an  average  of  around  1,400  subject  searches  were     engine  of  innovation:  building  the  high-­‐performance  catalog  |  owen  and  michalak       doi:  10.6017/ital.v34i2.5702   14   done  in  a  week.  approximately  one  month  into  the  spring  semester,  that  average  had  risen  to   around  4,000  subject  searches  per  week.  use  of  the  author  and  title  indexes  also  rose,  although   not  quite  as  dramatically.  in  the  perpetual  tug-­‐of-­‐war  between  precision  and  recall,  the  balance   had  decidedly  shifted.   another  service  that  we  provide,  which  is  especially  popular  with  students,  is  the  ability  to   produce  citations  formatted  in  one  of  several  commonly  used  bibliographic  styles,  including  apa,   mla,  and  chicago  (both  author-­‐date  and  note-­‐and-­‐bibliography  formats).  this  functionality,  first   introduced  by  ncsu  and  then  jointly  developed  with  unc  over  the  years  that  followed,  works  in   two  ways.  if  a  patron  finds  a  monographic  title  in  the  catalog,  simply  clicking  on  a  link  labeled  “cite”   produces  a  properly  formatted  citation  that  can  then  be  copied  and  pasted  into  a  document.  the   underlying  technology  also  powers  a  “citation  builder”  function  by  which  a  patron  can  enter  basic   bibliographic  information  for  a  book,  a  chapter  or  essay,  a  newspaper  or  journal  article,  or  a   website  into  a  form,  click  the  “submit”  button,  and  receive  a  citation  in  the  desired  format.     an  additional  example  of  innovation  that  falls  somewhat  outside  the  scope  of  the  changes   discussed  above  was  the  development  of  a  system  that  allowed  for  the  mapping  of  simplified   chinese  characters  to  their  traditional  counterparts.  searching  in  non-­‐roman  character  sets  has   always  offered  a  host  of  challenges  to  library  catalog  users.  the  trln  libraries  have  embraced  the   potential  of  endeca  to  reduce  some  of  these  challenges,  particularly  for  chinese,  through  the   development  of  better  keyword  searching  strategies  and  the  automatic  translation  of  simplified  to   traditional  characters.   since  we  had  complete  control  over  the  endeca  interface,  it  proved  relatively  simple  to  integrate   document  delivery  services  directly  into  the  functionality  of  the  catalog.  rather  than  simply   emailing  a  bibliographic  citation  or  a  call  number  to  themselves,  patrons  could  request  the   delivery  of  library  materials  directly  to  their  campus  addresses.  once  we  had  implemented  this   feature,  we  quickly  moved  to  amplify  its  power.  many  catalogs  offer  a  “shopping  cart”  service  that   allows  patrons  to  compile  lists  of  titles.  one  variation  on  this  concept  that  we  believe  is  unique  to   our  library  is  the  ability  for  a  professor  to  compile  such  a  list  of  materials  held  by  the  libraries  on   campus  and  submit  that  list  directly  to  the  reserve  reading  department,  where  the  books  are   pulled  from  the  shelves  and  placed  on  course-­‐reserve  lists  without  the  professor  needing  to  visit   any  particular  library  branch.  these  new  features,  in  combination  with  other  service   enhancements  such  as  the  delivery  of  physical  documents  to  campus  addresses  from  our  on-­‐ campus  libraries  and  our  remote  storage  facility,  have  increased  the  usefulness  of  the  catalog  as   well  as  our  users’  satisfaction  with  the  library.  we  believe  that  these  changes  have  contributed  to   the  ongoing  vitality  of  the  catalog  and  to  its  continued  importance  to  our  community.   in  december  2012,  the  libraries  adopted  proquest’s  summon  to  provide  enhanced  access  to   article  literature  and  electronic  resources  more  generally.  at  the  start  of  the  following  fall   semester,  the  libraries  instituted  another  major  change  to  our  discovery  and  delivery  services   through  a  combined  single-­‐search  box  on  our  home  page.  this  has  fundamentally  altered  how     information  technology  and  libraries  |  june  2015     15   patrons  interact  with  our  catalog  and  its  associated  resources.  first,  because  we  are  now   searching  both  the  catalog  and  the  summon  index,  the  type-­‐ahead  feature  that  we  had  deployed  to   suggest  index  terms  from  our  local  database  to  users  as  they  entered  search  strings  no  longer   functions  as  an  authority  index  search.  we  have  returned  to  querying  both  databases  through  a   simple  keyword  search.     second,  in  our  implementation  of  the  single  search  interface  we  have  chosen  to  present  the  results   from  our  local  database  and  the  retrievals  from  summon  in  two,  side-­‐by-­‐side  columns.  this  has   the  advantage  of  bringing  article  literature  and  other  resources  indexed  by  summon  directly  to   the  patron’s  attention.  as  a  result,  more  patrons  interact  directly  with  articles,  as  well  as  with   books  in  major  digital  repositories  like  google  books  and  hathitrust.  this  change  has   undoubtedly  led  patrons  to  make  less  in-­‐depth  use  of  the  local  catalog  database,  although  it   preserves  much  of  the  added  functionality  in  terms  of  discovering  our  own  digital  collections  as   well  as  those  resources  whose  cataloging  we  share  with  our  trln  partners.  we  believe  that  the   ease  of  access  to  the  resources  indexed  by  summon  complements  the  enhancements  we  have   made  to  our  local  catalog.   conclusion  and  further  directions   one  might  argue  that  the  integration  of  electronic  resources  into  the  “catalog”  actually  shifts  the   paradigm  more  significantly  than  any  previous  enhancements.  as  the  literature  review  indicates,   much  of  the  conversation  about  enriching  library  catalogs  has  centered  on  improving  the  means   by  which  search  and  discovery  are  conducted.  the  reasonably  direct  linking  to  full  text  that  is  now   possible  has  once  again  radically  shifted  that  conversation,  for  the  catalog  has  come  to  be  seen  not   simply  as  a  discovery  platform  based  on  metadata  but  as  an  integrated  system  for  delivering  the   essential  information  resources  for  which  users  are  searching.   once  the  catalog  is  understood  to  be  a  locus  for  delivering  content  in  addition  to  discovering  it,  the   local  information  ecosystem  can  be  fundamentally  altered.  at  unc-­‐chapel  hill  we  have  engaged  in   a  process  whereby  the  catalog,  central  to  the  library’s  web  presence  (given  the  prominence  of  the   single  search  box  on  the  home  page),  has  become  a  hub  from  which  many  other  services  are   delivered.  the  most  obvious  of  these,  perhaps,  is  a  system  for  the  delivery  of  physical  documents   that  is  analogous  to  the  ability  to  retrieve  the  full  text  of  electronic  documents.  if  an  information   source  is  discovered  that  exists  in  the  library  only  in  physical  form,  enhancements  to  the  display  of   the  catalog  record  facilitate  the  receipt  by  the  user  of  the  print  book  or  a  scanned  copy  of  an  article   from  a  bound  journal  in  the  stacks.     in  2013,  ithaka  s+r  conducted  a  local  unc  faculty  survey.  the  survey  posed  three  questions   related  to  the  catalog.  in  response  to  the  question,  “typically  when  you  are  conducting  academic   research,  which  of  these  four  starting  points  do  you  use  to  begin  locating  information  for  your   research?,”  41  percent  chose  “a  specific  electronic  research  resource/computer  database.”  nearly   one-­‐third  (30  percent)  chose  “your  online  library  catalog.”17     engine  of  innovation:  building  the  high-­‐performance  catalog  |  owen  and  michalak       doi:  10.6017/ital.v34i2.5702   16   when  asked,  “when  you  try  to  locate  a  specific  piece  of  secondary  scholarly  literature  that  you   already  know  about  but  do  not  have  in  hand,  how  do  you  most  often  begin  your  process?,”  41   percent  chose  the  library’s  website  or  online  catalog,  and  40  percent  chose  “search  on  a  specific   scholarly  database  or  search  engine.”  in  response  to  the  question,  “how  important  is  it  that  the   library  .  .  .  serves  as  a  starting  point  or  ‘gateway’  for  locating  information  for  my  research?,”  78   percent  answered  extremely  important.     on  several  questions,  ithaka  provided  the  scores  for  an  aggregation  of  unc’s  peer  libraries.  for   the  first  question  (the  starting  point  for  locating  information),  18  percent  of  national  peers  chose   the  online  catalog  compared  to  30  percent  at  unc.  on  the  importance  of  the  library  as  gateway,  61   percent  of  national  peers  answered  very  important  compared  to  the  78  percent  at  unc.   in  2014,  the  unc  libraries  were  among  a  handful  of  academic  research  libraries  that  implemented   a  new  ithaka  student  survey.  though  we  don’t  have  national  benchmarks,  we  can  compare  our   own  student  and  faculty  responses.  among  graduate  students,  31  percent  chose  the  online  catalog   as  the  starting  point  for  their  research,  similar  to  the  faculty.18  of  the  undergraduate  students,  33   percent  chose  the  library’s  website,  which  provides  access  to  the  catalog  through  a  single  search   box.19   a  finding  that  approximately  a  third  of  students  began  their  search  on  the  unc  library  website   was  gratifying.  oclc’s  perceptions  of  libraries  2010  reported  survey  results  regarding  where   people  start  their  information  searches.  in  2005,  1  percent  said  they  started  on  a  library  website;   in  2010,  not  a  single  respondent  indicated  doing  so.20     the  gross  disparity  between  the  oclc  reports  and  the  ithaka  surveys  of  our  faculty  and  students   requires  some  explanation.  the  libraries  at  the  university  of  north  carolina  at  chapel  hill  are   proud  of  a  long  tradition  of  ardent  and  vocal  support  from  the  faculty,  and  we  are  not  surprised  to   learn  that  students  share  their  loyalty.  for  us,  the  recently  completed  ithaka  surveys  point  out   directions  for  further  investigation  into  our  patrons’  use  of  our  catalog  and  why  they  feel  it  is  so   critical  to  their  research.   anecdotal  reports  indicate  that  one  of  the  most  highly  valued  services  that  the  libraries  provide  is   delivery  of  physical  materials  to  campus  addresses.  some  faculty  admit  with  a  certain  degree  of   diffidence  that  our  services  have  made  it  almost  unnecessary  to  set  foot  in  our  buildings;  that  is  a   trend  that  has  also  been  echoed  in  conversations  with  our  peers.  yet  the  online  presence  of  the   library  and  its  collections  continues  to  be  of  significant  importance—perhaps  precisely  because  it   offers  an  effective  gateway  to  a  wide  range  of  materials  and  services.   we  believe  that  the  radical  redesign  of  the  online  public  access  catalog  initiated  by  north  carolina   state  university  in  2006  marked  a  sea  change  in  interface  design  and  discovery  services  for  that   venerable  library  service.  without  a  doubt,  continued  innovation  has  enhanced  discovery.   however,  we  have  come  to  realize  that  discovery  is  only  one  function  that  the  online  catalog  can   and  should  serve  today.  equally  if  not  more  important  is  the  delivery  of  information  to  the     information  technology  and  libraries  |  june  2015     17   patron’s  home  or  office.  the  integration  of  discovery  and  delivery  is  what  sets  the  “next-­‐gen”   catalog  apart  from  its  predecessors,  and  we  must  strive  to  keep  that  orientation  in  mind,  not  only   as  we  continue  to  enhance  the  catalog  and  its  services,  but  as  we  ponder  the  role  of  the  library  as   place  in  the  coming  years.  far  from  being  in  decline,  the  online  catalog  continues  to  be  an  “engine   of  innovation”  (to  borrow  a  phrase  from  holden  thorp,  former  chancellor  of  unc-­‐chapel  hill)  and   a  source  of  new  challenges  for  our  libraries  and  our  profession.   references     1.     cathy  de  rosa  et  al.,  perceptions  of  libraries  and  information  resources:  a

reviews key papers in informatwn science. edited by arthur w. elias. washington, d.c.: american society for information science, 1971. 223 p. $6.00. when i re-read the articles making up this volume for the purpose of writing this review, a strong feeling of nostalgia welled up. as a reader who has lived t?rough the years of speculation, exploration, experiment, development, and debate that they embody, i couldn't help but feel again the spirit of excitement that i and others felt at the time. these are indeed "key papers," and it's valuable to have them together. oh, of course some names are missing and are missedmooers, taube, fairthorne, perry and kent, bar-hillel, bush, shaw-but enough of them are here to give a full flavor of the times. the question is whether, as a collection, this set of papers has value beyond nostalgia. before turning to that question, however, let's see what they consist of. the volume groups nineteen papers into four categories: (1) background and philosophy, (2) information needs and systems, ( 3) organization and dissemination of information, and ( 4) other areas of interest. the first includes papers by borko, by shera, and by otten and debons that attempt to define information science, its relationship to librarianship, and its potential as an independent discipline. the second includes papers by weinberg, by murdock and liston, by taylor, by parker and paisley, and by kertesz that outline the purposes and functions of information transfer, especially for the sciences. the third includes papers by doyle, by fischer, by conner, and by rees that present some of the techniques which have been developed for handling, organizing, and presenting information-especially mechanized ones such as kwic indexes, automatic indexing and abstracting, and sdi. the final section presents a potpourri of topics: a paper by lipetz on information storage book reviews 269 and retrieval, one by de gennaro on library automation, one by garvin on natural language, one by borko on systems analysis, and one by heilprin on technology and copyright. the defined purpose of this collection is to serve students and instructors in introductory courses in information science, by making these key papers readily available as assigned readings. they indeed are useful readings, and the organization imposed on them by the editor, elias, adds greatly to their usefulness, making them far more than a simple chronological listing. despite this, however, i must confess that, as the instructor in an introductory course in which we used the key papers for the purpose for which it was intended, it fell short of meeting the needs. since then, i've tried to evaluate why. recognizing that the difficulties may have been due to the style of the instructor and the form of the course the fact is that any collection of readings: valuable though they individually may be, has many deficiencies. i suppose they can all be summed up as follows: a collection of papers has the appearance of a book without being a book. it lacks congruity; it lacks balance; it lacks inherent structure in contrast to that which is imposed; it lacks a theme or point to be made; it lacks a consistent style. as a sometime publisher, as an editor of a -series of books as a reviewer of prospective manuscrip~ i have felt that these things are as important in

academic libraries in canada jasmine hoover information technology and libraries | december 2018 15 jasmine hoover (jasmine_hoover@cbu.ca) is scholarly resources librarian, cape breton university, sydney, nova scotia, canada. abstract modern academic libraries are hubs of technology, yet the gap between the library and it is an issue at several small university libraries across canada that can inhibit innovation and lead to diminished student experience. this paper outlines results of a survey of small (<5,000 fte) universities in canada, focusing on it and the library when it comes to organizational structure, staffing, and location. it then discusses higher level as well as smaller scale solutions to this issue. introduction modern academic libraries are hubs of technology, yet existing staffing, organizational structures, physical proximity and traditional ways of doing things in higher education have maintained a gap between the library and it, which is an issue at several small university libraries across canada. libraries today are largely online, which means managing access to resources, using online tools for reference and research, designing websites and more. the physical space in libraries is now a place to interact with new technologies, visualize data, a place for research support including open access repositories and data management, and other digital research initiatives. 1 these library functions often require a staffing complement to support them with a level of specialization in information technology (it). however, though the offerings of the library have changed drastically over the years, smaller university libraries have struggled to support the growing need for it services. larger universities (over 5,000 fte) have managed this influx of demand and usage of new technologies in libraries by having their own library it services to manage software and technologies to support research, teaching and learning. many also offer student and user -facing technical support with it help desks within the library. smaller universities (below 5,000 fte) often do not have the resources to have their own it department or staff and find themselves not able to help researchers with modern digital scholarship, not able to support new systems and software, and not working as closely with it as they would like or need. also, the it department is generally not responsible for this kind of work, as it is outside of institutional-wide software support. this paper outlines the current status of it and the library when it comes to organizational structure, physical location, and collaboration in small academic libraries across canada. it then outlines strategies that can be used in smaller libraries to help bridge the gap, as well as recommendations for administrators when considering organizational changes to better serve a modern research atmosphere. current status at small canadian universities the technologies behind modern library services are often complex, as libraries need to securely manage access to online resources (both on and off campus); support faculty as they research and mailto:jasmine_hoover@cbu.ca gaps in it and library services at small academic libraries in canada | hoover 16 https://doi.org/10.6017/ital.v37i4.10596 teach using new software and technologies; and support new models for publishing that include open-access repositories, data management, open education resources, and more. library staff deal with technology issues that come up daily, with several non-it library staff members troubleshooting and solving various issues that arise. library users run into all kinds of technical issues and reach out for help. in nova scotia, our library consortium offers live help, an online library chat service distributed throughout eleven academic institutions in nova scotia. statistics kept on type of question asked on this service from january 2010 to march 2018 show that 26 percent of the over 68,000 questions asked are technical in nature, with topics including difficulty accessing online resources, login troubles, and other technical issues.2 for this study, 18 out of the 21 universities with fte >1,000 and < 5,000 in canada were surveyed. excluded were universities that were “sister” institutions of larger universities which utilized the same library system and french-only-speaking universities. twelve university libraries responded to an online survey which asked questions concerning organization and collaboration focused on it, the library, and educational technology. results (see figure 1) show that organizational reporting structures in higher education vary when it comes to it and the library. fifty percent of the survey respondents reported that their it department reports to the ceo/cfo or vp administrative, 25 percent of it departments report to a cio, 17 percent report to a provost/vp academic, and 8 percent report to a vp finance. figure 1. which of the following best describes how your it organization reports? all of the libraries in this survey, on the other hand, report to a provost or vp academic. this makes sense, as libraries are generally considered academic while it is usually associated with operations. however, there have been recent changes to some university library structures in canada that might indicate new thinking when it comes to organizational structure and the relationship between these units. in 2018, it was announced that there would be restructuring at brandon university which removed the university librarian position altogether (as well as the 50% 17% 25% 8% reports to ceo/cfo/vp admin reports to provost/ vp academic reports to cio reports to the vp finance information technology and libraries | december 2018 17 director of it services), and placed the library under a chief information officer. this would bring the library and it under one reporting structure.3 in an opposite move, mount allison university recently proposed to eliminate the top librarian position and have an academic dean split the responsibility of the library and their academic unit.4 after local outcry, this move was reversed and the job ad is out for a head librarian. it is hard to say if these are signals of upcoming change in the future of library reporting, or a temporary solution in a time of budget restrictions. however, half of the survey respondents mentioned that there has been some recent reorganization or planned reorganization related to it and the library at their institutions. only 33 percent of small university libraries surveyed have their own it department or staff. one of those libraries have an it specialist who splits time between the library and their it department. the other 67 percent have no it department or staff in the library (see figure 2). figure 2. does your library have its own it department? when asked, “is there anything you would like changed about the current organization when it comes to it and the library?,” all of the libraries without in-library it support mentioned a desire for either a position in the library responsible for it; greater collaboration between it and the library; or a specific person within the it department who they could contact regarding it. student experience, including their experience with technology is important according to a recent educause study. this 2017 educause study outlines the importance of it, and support for students when it comes to wi-fi and other technical support.5 one recommendation from this report is to have it help desks more visible and available. not only is the library a convenient location, but as we have already seen, students are increasingly using technologies in the library and often run into issues. it makes sense then to have an it help desk within the library, as the majority of larger university libraries in canada already offer. when asked about it help desks in 25% 67% 8% yes, they are library employees no gaps in it and library services at small academic libraries in canada | hoover 18 https://doi.org/10.6017/ital.v37i4.10596 the library, three of the responding university libraries (25 percent) have help desks staffed by it services, one (8 percent) had a help desk staffed by library staff, and another (8 percent) had an after-hours help desk staffed by it services. the remaining 59 percent have no it help available in the library (see figure 3). figure 3. does your library have an it help desk? the physical location of the two units is also important. in this survey, 75 percent of respondents replied that the library and the it department are in separate spaces while 25 percent share a common space. studies have shown that physical proximity in the workplace can lead to greater collaboration. an mit study showed that physical proximity drives collaboration between researchers on university campuses.6 as one of the common themes in the survey was the desire for more collaboration, a physical change of location could have a great impact. when asked about changes people would like to see with the current organization of the it and library, many mention a need for more collaboration due to interrelated responsibilities. common suggestions included library it staff, having an it help desk in the library, or a specific person in it they could contact directly for help or who had shared responsibilities between it and the library. another suggestion was a committee that would bring together members from both units to strengthen communication. what can be done? in the larger view, university administrations need to look for outdated governance and organizational structures that are in place. as universities shift their goals and focus over time, they need to adapt structures and staffing accordingly. chong and tan describe it govern ance as being of utmost importance, claiming there needs to be strategic alignment between it and organizational strategies and objectives.7 carraway describes universities with a high level of it governance maturity and effectiveness as those where “it initiatives are aligned with the 59%25% 8% 8% no yes, employed by it services yes, employed by the library yes, employed by it services, only after hours information technology and libraries | december 2018 19 institution’s strategic priorities and prioritized among the university’s portfolio projects.” 8 effective it governance, focused on collaboration and communication, is associated with greater integration of innovation into institutional process. also, it governance was found to be more effective under a delegated model that empowers it governance bodies than under a cio centric model. the majority of universities surveyed showed common governance structures of it, with most as separate units reporting to a cfo/vp admin or similar. the inclusion of faculty, students , and business units in it governance committees was associated with a stronger innovation culture.9 stakeholder inclusion is an important characteristic of it governance maturity. students, as consumers of it, and faculty should both have a seat at the table when it comes to it governance. carraway found that an increased level of student engagement in it governance correlates with a high level of innovation culture.10 university administration should take a good look at how it is governed, who has input and how it is affecting the university’s objectives. the reporting structure of libraries has generally gone unchanged, with most respondents confirming that their library reports to an academic vice president. budget constraints at two canadian universities have seen the library structure being impacted as of late, however there has been little research done on the ideal governance structure of libraries in higher education. both it and the library in smaller canadian universities could consider governance committees that include students, faculty and other stakeholders, in order to be more innovative and effective. it is an interesting unit, where the model in higher education has moved back and forth between three main structures: centralized, decentralized, and federated it structures. centralized, where there is a central hub that runs it services for the university, is the most common structure found at the surveyed universities. decentralized, where it services are spread throughout the organization, would automatically mean the library (and other units) had it staff. a federated model would also lead to local library it work being done by specific people, who work for and out of a central it office, but are assigned to specific areas. federated structures offer centralized control, with decentralized functions in faculties and units. chong and tan believe that federated structures are more appropriate for a collaborative network, such as a university.11 their study found that federated structure, combined with coordinated communication, led to higher effectiveness. nugroho maintains that decentralized organizations such as universities need to regularly review their it governance structure, as both technology and the organization itself changes.12 he maintains that effective governance does not happen by coincidence, and it governance is not a static concept. library staffing also needs to change based on needs of the users and goals of the organization. some even suggest that libraries reorganize every few years to keep staff flexible, take advantage of new opportunities and foster growth.13 in 2011, we saw bell and shank’s work on the blended librarian, which advocated for librarianship with educational technology and instructional design skills.14 according to the 2015 arl statistics, we continue to see nontraditional professional jobs increasing in the library. in 2015, the top three new hire categories included two nontraditional categories: digital specialists and functional specialists.15 arcl statistics from 2016 showed that over the previous five years, 61 percent of libraries repurposed or cross-trained staff to better support new technologies or services.16 we saw in the survey that out of over 68,000 research questions fielded by librarians across nova scotia since 2010, just over one quarter of these are technical in nature. library administration at smaller universities, looking at these numbers, gaps in it and library services at small academic libraries in canada | hoover 20 https://doi.org/10.6017/ital.v37i4.10596 should respond by ensuring that technical knowledge and skills will be written into job ads, as they are increasingly in demand or that staff are trained appropriately. physical location is also important. we’ve seen from the survey results that there is a lack of physical connectedness between the library and it in smaller canadian universities. wineman et al. studied various organizations and their physical proximity. they state: “social networks play important roles in structuring communication, collaboration, access to knowledge and knowledge transformation.”17 they suggest that innovation is a process that occurs at the crossroad between social and physical space. cramton points out that “maintaining mutual knowledge is a central problem of geographically dispersed collaboration.”18 if it is not possible to change the organizational structure or governance to ensure more communication and knowledge sharing, physical spaces such as an it desk in the library is another way for the library and it staff to be in regular contact. a 2017 mit study recommended that institutions keen to support the crossdisciplinary collaborative activity that is vital to research and practice, may need to adopt “a new approach to socio-spatial organisation that may ultimately enrich the design and operation of places for knowledge creation.”19 we could apply the same thinking to institutions interested in supporting collaborative activity between the library, it, and newer-yet-related initiatives such as educational technology and digital research centers. proximity to collaborators should be considered as one option to enhance outcomes and innovation between the library and it. organizational structures and models, physical locations, and governance are all large-scale factors that should be considered when looking at the relationship between it and the library. there are also smaller-scale practical ideas that can help. these ideas will be discussed below. an important first step is to start the conversation. the author’s institution has begun thinking about the gaps in our services and support for research, especially when it comes to support for technologies needed for modern research and publication that are often housed in the library. factors which have helped start this conversation include: funding mandates related to open access and data management; new services or initiatives that researchers or units would like to start; which require it and library specialization; and planning for a future in higher education that increasingly relies on up to date technologies to support research, publishing, and teaching. a conversation is beginning between researchers, administration, the library, and other stakeholders which will lead to a collaborative solution to some of these issues. it’s important that there is interest and initiation from administration, but also that other stakeholders are involved from the onset. many universities have developed new positions, new units, or worked these positions into it or the library to fill this gap, but the solution needs to fit each institution and their goals. often times when there is no it staff in the library, technical issues are managed by one or two technical-minded staff members. equipping frontline service providers may help alleviate some of this work by enabling many staff to solve common technical issues. here at the author’s institution, the librarian in charge of access has begun presenting common technical/access issues during a monthly reference meeting. the goal is to have all staff who field questions from users have a basic understanding of how the systems work in the library, what to do if they see issues, and whom they can contact. in libraries where there is not a strong it presence, it is important to enable staff to be comfortable with basic issues that will come up. this also ensures that there is not just one person who can answer common technical/access issues. if someone staffing the information technology and libraries | december 2018 21 reference or circulation desk encounters users with these issues, they can explain why they are happening and what the library is going to do to help them. the plan is to create a library technical manual out of these quick presentations that can act as a resource for all staff or as a training manual for new staff. at each of these presentations, a survey is administered. the survey has four questions and asks participants about their comfort level dealing with technical/access questions both before and after the presentation. one hundred percent of staff answered that after the presentation, they felt more comfortable when encountering the issues described. this is not a suitable replacement of the specialized it skills needed in libraries; however, it can alleviate some of the pressure put on select people in smaller academic libraries. library staff can, and do, actively work to learn new skills through formal training and professional development. we saw from the acrl survey that many libraries are working to cross-train staff in order to keep up with technological demands. encouraging learning new skills and educational opportunities can go a long way and should be encouraged by library administration. the benefit of having it staff dedicated to the library is obvious, and libraries should continually push for this. results of the survey showed that library staff would prefer to have a person to contact with issues specific to the library. issues can be dealt with promptly, it personnel working in or assigned to the library will have an understanding of the systems involved, communication is easier, as there is a point person to contact, and the library has control over the products and services they offer. however, if that is not possible within the organization, a good system of communication is important. a timely system of contacting it and resolving issues can go a long way. chong and tan maintain that a coordinated communication system is key for it in an organization.20 a commonly used system for technical issues is the ticket system, where issues can be submitted by users, and answered and tracked by it. this is a very useful system for it staff, however the users often cannot track their own ticket, see a timeline for completion, or know who is on the other end to contact with more information. it is a good idea to meet regularly with it, formally or informally, to be able to discuss issues, build a relationship with colleagues, and get a better sense of how each unit works. on the library end, it is important to keep statistics on technical issues sent to it and the time elapsed before the issues are resolved. these statistics can be used to demonstrate the need for library-specific it staff, encourage better communication between departments, or demonstrate a problem with the current way issues are communicated. having statistics will help libraries if and when the time comes that new positions can be created. at the author’s institution we use springshare’s libanswers software to track all technical issues, including those sent on to it. this software records the dates and times; important details and resolutions to technical issues; and exports useful statistics. in smaller canadian university libraries there is a growing need for it support. however, there has been little done by way of organizational structure, staffing, or physical proximity between these two units to allow universities to better serve their students and faculty. this paper outlined the current situation in several smaller university libraries in canada and provides some high level as well as local solutions to this problem. gaps in it and library services at small academic libraries in canada | hoover 22 https://doi.org/10.6017/ital.v37i4.10596 appendix a: it, library, and

introduction current status at small canadian universities what can be done? appendix a: it, library, and educational technology organization references editorial board thoughts: doesn’t work mark cyzyk editorial board thoughts | cyzyk 3 the proof of the pudding’s in the eating. miguel de cervantes saavedra. the ingenious hidalgo don quixote de la mancha. part i, chapter xxxvii, john rutherford, trans. about fifteen years ago i had two students from germany working for me, jens and andreas. those guys were great. they were smart and funny and interesting and always did their best. i would send them out to fix things around the library, and they would dutifully report back with success or failure. i told them that, particularly if there was a problem with a staff workstation, “if it breaks in the morning, it must be fixed by lunchtime; if it breaks in the afternoon, it must be fixed by 5:00.” they understood that if a staff workstation was down, then that probably also meant a staff member was just sitting there, waiting for it to be fixed. if we had to we could slap a sign on a broken public workstation and get back to it later—there were plenty of other working public stations after all—but staff workstations must be working at all times. insofar as we had an aged fleet of pcs whose cmos batteries were rapidly giving out, i kept jens and andreas running around the building quite a bit. on occasion, though, they would report back with the dreaded, “hey boss, doesn’t work.” this was the one thing that would raise my ire. “of course it doesn’t work, that’s why i sent you down there!” i would think. the phrase “doesn’t work” became for me a pavlovian signal that i was about to drop everything and go take a look myself. it now occurs to me, though, that this notion of “work” is precisely the point of technology, and that sometimes this gets lost for those of us employed fulltime as technologists in libraries. let me explain: in my opinion and for the most part, the proper role of the technologist in a library is that of a consultant on loan to the departments to work on projects there, embedded.1 two of the best bosses i ever had said essentially the same thing to me in our introductory first-day-on-the-job chit-chat: “you report to me, but you work for them.” such is the proper attitude in any serviceoriented profession. does this not frequently get inverted, subverted, lost? what happens is that technology starts to take on an importance undeserved. it becomes selfreferential and insular; a technology-for-technology’s-sake attitude arises. mark cyzyk (mcyzyk@jhu.edu) is scholarly communication architect in the sheridan libraries, john hopkins university. mailto:mcyzyk@jhu.edu information technology and libraries | june 2012 4 but technology-for-technology’s-sake is just wrong. technology is merely a means to an end, not an end in itself. the word itself derives from the ancient greek technê, most frequently translated into english as “craft” and frequently distinguished in the greek philosophical literature from epistêmê or (certain) knowledge.2 so it is here that the crucial distinction in the western world between practical and theoretical activities is made, and technology is clearly a practical, not theoretical activity. as such, it has by its very nature practical outcomes in the world: technology works in the world. technology is instrumental in achieving certain practical outcomes; its value is as a tool, instrumentally valuable, not inherently valuable. it is not for its own sake that we implement technology; we implement technology to get some sort of work accomplished in the world. our programming languages, application servers, web application frameworks, ajax libraries, integrated development environments, source-code repositories, build tools, testing harnesses, switches, routers, single-signon utilities, proxy servers, link resolvers, repositories, bibliographic management utilities, help-desk ticketing applications, and elaborate project-management protocols are all for naught if the final product of our labor, at the end of the day, doesn’t work. our product is not only literally useless, it is worse than useless because the library in which we labor has devoted precious resources to it only to result in a service or product that does not properly function, and those are precious resources that could have been spent elsewhere. hey there fellow technologists, why am i being so dismal? i would prefer the term “grave” to “dismal.” significant portions of the library budget are put toward technology each year, and as those whose duty it is to carry our local technology strategies into the future, we need to always be mindful of the fact that each and every dollar spent on technology is a dollar not available for building our collections—surely the direct center of the mission of anyone who calls himself a librarian, a.k.a., a cultural conservationist. (shouldn’t we be wearing badges that read, “to collect and preserve”?) making it work is job one for the technologist in the library. … a colleague and friend of mine once told me, a decade ago, that our fellow colleague made a snippy comment about an important and major web application i had written, “just because it works doesn’t mean it’s right.” now, admittedly, i was a very sloppy code formatter, and yet i certainly would never say that the applications i wrote were steaming plates of spaghetti. on the contrary, i think the code i wrote consisted of good, solid procedural programming. what my disgruntled colleague meant, i think, was that i failed to follow a framework, and by “framework” he naturally meant the same framework to which he’d recently hitched his own coding wagon. my response to his snippiness was, “ah, pretty-it-up all you want, organize it any-which-way, but functional code-code that works--is actually the number one criterion for being good code.” just ask your clients. editorial board thoughts | cyzyk 5 that app i wrote has been in production, happily working away as a key piece of the enterprise network infrastructure at a prominent, multi-campus, east coast university since 2002.3 references 1. and here i heartily agree with my fellow editorial board member, michael witt, when he notes that “[p]art of this process is attempting to feel our users’ pain…”, and i even extend this to the point of us technologists actively working with our users toward a common goal, literally sitting with them, among them, not merely being present to offer occasional support, not merely feeling their pain but being so invested in our common project that their pain is our pain. [did i really just suggest we take on more pain?! yep.] see: michael witt. “eating our own dogfood.” information technology and libraries 30, no. 3 (september 2011) 90. http://www.ala.org/lita/ital/sites/ala.org.lita.ital/files/content/30/3/pdf/witt.pdf 2. i’m no classics scholar, but this is my recollection from taking a graduate seminar many years ago on this very topic. so while i’m not pulling this entirely out of thin air, i am pulling it from the musty mists of middle-aged memory – that, and a quick scan of professor richard parry’s fine article on this topic in the stanford encyclopedia of philosophy, particularly the section on aristotle’s views. regarding my comments below on technology being instrumentally valuable, i cite parry’s words: “presumably, then, the craftsman does not choose his activity for itself but for the end; thus the value of the activity is in what is made”. see: richard parry.

https://jscholarship.library.jhu.edu/handle/1774.2/32800 2 information technology and libraries | march 2008 currently we librarians seem to be hitching our wagon to the idea of library as community because in part it’s what we ourselves want. we’ve seen that our lita members want more community from our association, so it makes sense to us that our patrons also want community. it’s what pew, oclc, and other studies seem to be telling us. the business-wired side of the world is breaking their backs to create every form of virtual community they can think of as quickly as possible. apply the appropriate amounts of marketing and then our patrons want those things and expect them from all of their historically important community resources, the library being a prime player in that group. so we strive and strive and strive to not only provide the standard issue face-to-face community we’ve always created, but to also create that new highly desired virtual community. either we create a library-specific version, or we at the very least create a way for our patrons to access those communities. hopefully, when our patrons step into those virtual communities, we work to make it possible for them to find libraries there, too. all well and good, but do we have a plan? what’s the goal? what’s the end achievement? if, as studies say, patrons with a research need turn to libraries first only one percent of the time, and instead first hit up friends and family fifty or more percent of the time, then where is our significance and place in either the physical or virtual spaces? we know we serve significant numbers in many ways. we have gate counts, circulation records, holds placed, warm bodies in the building—all manners of indicators that show a well-managed and -marketed library is in demand and appreciated. as we run into the terrible head-on crash of community and technology, willy-nilly doing absolutely everything we can to accommodate everyone and everything, because we’re librarians and library technologists and that’s what we do, do we really have a clue why we’re doing it? all fodder for deep thought and many lattes or beers and late night discussions. on the lita side, though, we’re embarking on doing something about this knot when it comes to serving our members. under the guidance of past-president bonnie postlethwaite we’ve established an assessment and research committee co-chaired by bonnie and diane bisom. to kick off the committee activities and to help them establish an agenda and direction, lita hired the research firm the wedewer group to work with the lita board and the new committee. stay tuned for reports and announcements from this committee as it works to find answers to some of those questions. and have that latte with a lita colleague as you seek to find some answers yourself. it’s all part of building community. mark beatty (mbeatty@wils.wisc.edu) is lita president 2007/2008 and trainer, wisconsin

2 andromeda yelton (andromeda.yelton@gmail.com) is lita president 2017-18 and senior software engineer, mit libraries, cambridge, united states. before i dive into my column, i’d like to recognize and thank bob gerrity for his six years of service as ital’s editor in chief. he oversaw our shift from a traditional print journal to a fully online one, recognized by micah vandegrift and chealsye bowley as having the strongest open-access policies of all lis journals (http://www.inthelibrarywiththeleadpipe.org/2014/healthyself/). i’d like to further extend a welcome to ken varnum as our new editor in chief. ken’s distinguished record of lita service includes stints on the ital editorial board and the lita board of directors, so he knows the journal very well and i am enthusiastic about its future under his lead. i’m particularly curious to see what will be discussed in ital under ken’s leadership because i’ve just come back from two outstanding conferences which drove home the significance of the issues we wrestle with in library technology, and i’m looking forward to a third. in early november, i attended lita forum in scenic denver. the schedule was packed with sessions on intriguing topics – too many, of course, for me to attend them all – but two in particular stand out to me. in one, sam kome detailed how he’s going about a privacy audit at the claremont colleges library. he walked us through an extensive – and sometimes surprising – list of places personally identifiable information can lurk on library and campus systems, and talked through what his library absolutely needs (which is less than he’d thought, and far less than the library has been logging without thinking about it). in the other, mary catherine lockmiller took a design thinking approach to serving transgender populations. she shared a fantastic, practical libguide (http://libguides.southmountaincc.edu/transgenderresources), but the part that stuck with me most is her statement that many trans people may never physically enter a library because public spaces are not safe spaces; for this population, our electronic services are our public services. as technologists, we create the point of first, and maybe only, contact. a week later, i attended the inaugural data for black lives conference (http://d4bl.org/) at the mit media lab, steps from my office. this was – and i think everyone in the room felt it – something genuinely new. from the galvanizing topic, to the sophisticated visual and auditory design, to the frisson of genius and creativity buzzing all around a room of artists, activists, professors, poets, data scientists and software engineers, it was a remarkable experience for us all. those of you who heard dr. safiya noble speak at thomas dowling’s lita president’s program in 2016 are familiar with algorithmic bias. numerous speakers discussed this at d4bl: the ways that racial disparities in underlying data sets can be replicated, magnified, and given a veneer of objective power when run through the black boxes that power predictive policing or risk assessment for bail hearings. absent and messy data was a theme as well: in a moment that would make many librarians chuckle (and then wince) knowingly, a panel of music industry executives estimated that 40% of their metadata is wrong, thus making it impossible to credit and compensate artists appropriately. mailto:andromeda.yelton@gmail.com)

http://libguides.southmountaincc.edu/transgenderresources http://d4bl.org/) president’s message | yelton 3 https://doi.org/10.6017/ital.v36i4.10238 and yet – in a memorable keynote – dr. ruha benjamin called on us not only to collect data about black death, as she showed us an image of the ambulance bill sent to tamir rice’s family, but to listen to our artists and poets as we use our data to imagine black life – this in front of an image of wakanda. with our data and our creativity, what new worlds can we map? several of my mit colleagues also attended d4bl, and as we discussed it afterward we started thinking about how these ideas can drive our own work. how does the imaginary world of wakanda connect to the archival imaginary, and what worlds can we empower our own creators to imagine with what we collect and preserve? how can we use our data literacy and access to sometimes un-googleable resources to help community groups collate data on important issues that are not tracked by our public institutions, such as police violence (https://mappingpoliceviolence.org/) or racial disparities in setting bail? with these ideas swirling in my mind, i am looking forward with tremendous excitement to lita forum 2018. building on the work of our forum assessment task force, we’ll be doing a lot of things differently; in particular, aiming for lots of hands-on, interactive sessions. this will be a conference where, whether you’re a presenter or an attendee, you’ll be able to do things. and these last two conferences have driven home for me how very much there is to do in of library technology. our work to select, collect, preserve, clean, and provide access to data can indeed have enormous impact. technology services are front-line services.

 semi-­‐automatic  metadata  generation  tools  is  particularly   important  considering  the  rapid  development  of  digital  repositories  and  the  recent  explosion  of  big   data.  utilization  of  semi-­‐automatic  metadata  generation  is  critical  in  addressing  these   environmental  changes  and  may  be  unavoidable  in  the  future  considering  the  costly  and  complex   operation  of  manual  metadata  creation.  to  address  such  needs,  this  study  examines  the  range  of   semi-­‐automatic  metadata  generation  tools  (n  =  39)  while  providing  an  analysis  of  their  techniques,   features,  and  functions.  the  study  focuses  on  open-­‐source  tools  that  can  be  readily  utilized  in  libraries   and  other  memory  institutions.  the  challenges  and  current  barriers  to  implementation  of  these  tools   were  identified.  the  greatest  area  of  difficulty  lies  in  the  fact  that  the  piecemeal  development  of  most   semi-­‐automatic  generation  tools  only  addresses  part  of  the  issue  of  semi-­‐automatic  metadata   generation,  providing  solutions  to  one  or  a  few  metadata  elements  but  not  the  full  range  of  elements.   this  indicates  that  significant  local  efforts  will  be  required  to  integrate  the  various  tools  into  a   coherent  set  of  a  working  whole.  suggestions  toward  such  efforts  are  presented  for  future   developments  that  may  assist  information  professionals  with  incorporation  of  semi-­‐automatic  tools   within  their  daily  workflows.     introduction   with  the  rapid  increase  in  all  types  of  information  resources  managed  by  libraries  over  the  last   few  decades,  the  ability  of  the  cataloging  and  metadata  community  to  describe  those  resources  has   been  severely  strained.  furthermore,  the  reality  of  stagnant  and  decreasing  library  budgets  has   prevented  the  library  community  from  addressing  this  issue  with  concomitant  staffing  increases.   nevertheless,  the  ability  of  libraries  to  make  information  resources  accessible  to  their   communities  of  users  remains  a  central  concern.  thus  there  is  a  critical  need  to  devise  efficient   and  cost  effective  ways  of  creating  bibliographic  records  so  that  users  are  able  to  find,  identify,   and  obtain  the  information  resources  they  need.     one  promising  approach  to  managing  the  ever-­‐increasing  amount  of  information  is  with  semi-­‐ automatic  metadata  generation  tools.  semi-­‐automatic  metadata  generation  tools     jung-­‐ran  park  (jung-­‐ran.park@drexel.edu)  is  editor,  journal  of  library  metadata,  and  associate   professor,

 university,  philadelphia.     evaluation  of  semi-­‐automatic  metadata  generation  tools|  park  and  brenza     doi:  10.6017/ital.v34i3.5889   23   concern  the  use  of  software  to  create  metadata  records  with  varying  degrees  of  supervision  from  a   human  specialist.1  in  its  ideal  form,  semi-­‐automatic  metadata  generation  tools  are  capable  of   extracting  information  from  structured  and  unstructured  information  resources  of  all  types  and   creating  quality  metadata  that  not  only  facilitate  bibliographic  record  creation  but  also  semantic   interoperability,  a  critical  factor  for  resource  sharing  and  discovery  in  the  networked  environment.   through  the  use  of  semi-­‐automatic  metadata  generation  tools,  the  library  community  has  the   potential  to  address  many  issues  related  to  the  increase  of  information  resources,  the  strain  on   library  budget,  the  need  to  create  high-­‐quality,  interoperable  metadata  records,  and,  ultimately,   the  effective  provision  of  information  resources  to  users.   there  are  many  potential  benefits  to  semi-­‐automatic  metadata  generation.  the  first  is  scalability.   because  of  the  quantity  of  information  resources  and  the  costly  and  time-­‐consuming  nature  of   manual  metadata  generation,2  it  is  increasingly  apparent  that  there  simply  are  not  enough   information  professionals  available  for  satisfying  the  metadata-­‐generation  needs  of  the  library   community.  semi-­‐automatic  metadata  generation,  on  the  other  hand,  offers  the  promise  of  using   high  levels  of  computing  power  to  manage  large  amounts  of  information  resources.  in  addition  to   scalability,  semi-­‐automatic  metadata  generation  also  offers  potential  cost  savings  through  a   decrease  in  the  time  required  to  create  effective  records.  furthermore,  the  time  savings  would   allow  information  professionals  to  focus  on  tasks  that  are  more  conceptually  demanding  and  thus   not  suitable  for  automatic  generation.  finally,  because  computers  can  perform  repetitive  tasks   with  relative  consistency  when  compared  to  their  human  counterparts,  automatic  metadata   generation  promises  the  ability  to  create  more  consistent  records.  a  potential  increase  in   consistency  of  quality  metadata  records  would,  in  turn,  increase  the  potential  for  interoperability   and  thereby  the  accessibility  of  information  resources  in  general.  thus  semi-­‐automatic  metadata   generation  offers  the  potential  to  not  only  ease  resource  description  demands  on  the  library   community  but  also  to  improve  resource  discovery  for  its  users.     goals  of  the  study   assessment  of  the  current  landscape  of  semi-­‐automatic  metadata  generation  tools  is  particularly   important  considering  the  fast  development  of  digital  repositories  and  the  recent  explosion  of   data  and  information.  utilization  of  semi-­‐automatic  metadata  generation  is  critical  to  address  such   environmental  changes  and  may  be  unavoidable  in  the  future  considering  the  costly  and  complex   operation  of  manual  metadata  creation.  even  though  there  are  promising  experimental  studies   that  exploit  various  methods  and  sources  for  semi-­‐automatic  metadata  generation,3  a  lack  of   studies  assessing  and  evaluating  the  range  of  tools  have  been  developed,  implemented,  or   improved.  to  address  such  needs,  this  study  aims  to  examine  the  current  landscape  of  semi-­‐ automatic  metadata  generation  tools  while  providing  an  evaluative  analysis  of  their  techniques,   features,  and  functions.  the  study  primarily  focuses  on  open-­‐source  tools  that  can  be  readily   utilized  in  libraries  and  other  memory  institutions.  the  study  also  highlights  some  of  the   challenges  still  facing  the  continued  development  of  semi-­‐automatic  tools  and  the  current  barriers     information  technology  and  libraries  |  september  2015       24   to  their  incorporation  into  the  daily  workflows  for  information  organization  and  management.   future  directions  for  the  further  development  of  tools  are  also  discussed.     toward  this  end,  a  critical  review  of  the  literature  in  relation  to  semi-­‐automatic  metadata   generation  tools  published  from  2004  to  2014  was  conducted.  databases  such  as  library  and   information  sciences  abstracts  and  library,  information  science  and  technology  abstracts  were   searched  and  germane  articles  identified  through  review  of  titles  and  abstracts.  because  the   problem  of  creating  viable  tools  for  the  reliable  automatic  generation  of  metadata  is  a  not  a   problem  limited  to  the  library  and  information  science  professions,4  database  searches  were   expanded  to  include  those  databases  pertinent  to  the  computing  science,  including  proquest   computing,  academic  search  premier,  and  applied  science  and  technology.  keywords,  such  as   “automatic  metadata  generation,”  “metadata  extraction,”  “metadata  tools,”  and  “text  mining,”   including  their  stems,  were  used  to  explore  the  databases.  in  addition  to  keyword  searching,   relevant  articles  were  also  identified  within  the  reference  sections  of  articles  already  deemed   pertinent  to  the  focus  of  the  survey  as  well  as  through  the  expansion  of  results  lists  through  the   application  of  relevant  subject  terms  applied  to  pertinent  articles.  to  ensure  that  the  latest,  most   reliable  developments  in  automatic  metadata  were  reviewed,  various  filters,  such  as  date  range   and  peer-­‐review,  were  employed.  once  tools  were  identified,  their  capabilities  were  tested  (when   possible),  their  features  were  noted,  and  overarching  developments  were  determined.     the  remainder  of  the  article  provides  an  overview  of  the  primary  techniques  developed  for  the   semi-­‐automatic  generation  of  metadata  and  a  review  of  the  open-­‐source  metadata  generation   tools  that  employ  them.  the  challenges  and  current  barriers  to  semi-­‐automatic  metadata  tool   implementation  are  described  as  well  as  suggestions  for  future  developments  that  may  assist   information  professionals  with  integration  of  semi-­‐automatic  tools  within  the  daily  workflow  of   technical  services  departments.     current  techniques  for  the  automatic  generation  of  metadata   as  opposed  to  manual  metadata  generation,  semi-­‐automatic  metadata  generation  relies  on   machine  methods  to  assist  with  or  to  complete  the  metadata-­‐creation  process.  greenberg   distinguished  between  two  methods  of  automatic  metadata  generation:  metadata  extraction  and   metadata  harvesting.5  metadata  extraction  in  general  employs  automatic  indexing  and   information  retrieval  techniques  to  generate  structured  metadata  using  the  original  content  of   resources.  on  the  other  hand,  metadata  harvesting  concerns  a  technique  to  automatically  gather   metadata  from  individual  repositories  in  which  metadata  has  been  produced  by  semi-­‐automatic  or   manual  approaches.  the  harvested  metadata  can  be  stored  in  a  central  repository  for  future   resource  retrieval.   within  this  dichotomy  of  extraction  methods,  there  are  several  other  more  specific  techniques   that  researchers  have  developed  for  the  semi-­‐automatic  generation  of  metadata.  polfreman  et  al.   identified  an  additional  six  techniques  that  have  been  developed  over  the  years:  meta-­‐tag   harvesting,  content  extraction,  automatic  indexing,  text  and  data  mining,  extrinsic  data  auto     evaluation  of  semi-­‐automatic  metadata  generation  tools|  park  and  brenza     doi:  10.6017/ital.v34i3.5889   25   generation,  and  social  tagging.6  although  the  last  technique  is  not  properly  a  semi-­‐automatic   metadata  generation  technique  because  it  is  used  to  generate  metadata  with  a  minimum  of   intervention  required  by  metadata  professionals,  it  can  be  viewed  as  a  possible  mode  to   streamline  the  metadata  creation  process.     both  greenberg  and  polfreman  provide  comprehensive,  high-­‐level  characterizations  of  the   techniques  employed  in  current  semi-­‐automatic  metadata  generation  tools.  however,  an   evaluation  of  these  techniques  within  the  context  of  a  broad  survey  of  the  tools  themselves  and  a   comprehensive  enumeration  of  currently  available  tools  are  not  addressed.  thus,  although  these   techniques  will  be  examined  for  the  remainder  of  this  section,  they  serve  simply  as  a  framework   through  which  this  study  provides  a  current  and  comprehensive  analysis  of  the  tools  available  for   use  today.  each  section  provides  an  overview  of  the  relevant  technique,  a  discussion  of  the  most   current  research  related  to  it,  and  the  tools  that  employ  that  technique.   the  tables  included  in  each  section  provide  lists  of  the  semi-­‐automatic  metadata  generation  tools   (n  =  39)  evaluated  in  the  course  of  this  survey.  the  information  presented  in  the  tables  is   designed  to  provide  a  characterization  of  each  tool:  its  name,  its  online  location,  the  technique(s)   used  to  generate  metadata,  and  a  brief  description  of  the  tool’s  functions  and  features.  only  those   tools  that  are  currently  available  for  download  or  for  use  as  web  services  at  the  time  of  this   writing  are  included.  furthermore,  the  listed  tools  have  not  been  strictly  limited  to  metadata-­‐ generation  applications  but  also  include  some  content  management  system  software  (cmss)  as   these  generally  provide  some  form  of  semi-­‐automatic  metadata  extraction.  typically,  cmss  are   capable  of  extracting  technical  metadata  as  well  as  data  that  can  found  in  the  meta-­‐tags  of   information  resources,  such  as  the  file  name,  and  using  that  information  as  the  title  of  a  record.     meta-­‐tag  extraction   meta-­‐tag  extraction  is  a  computing  process  whereby  values  for  metadata  fields  are  identified  and   populated  through  an  examination  of  metadata  tags  within  or  attached  to  a  document.  in  other   words,  it  is  a  form  of  metadata  harvesting  and,  possibly,  conversion  of  that  metadata  into  other   formats.  marcedit,  the  most  widely  used  semi-­‐automatic  tool  for  the  generation  of  metadata  in  us   libraries,7  is  an  example  of  this  technique.  marcedit  essentially  harvests  metadata  from  open   archives  initiative  protocol  for  metadata  harvesting  (oai-­‐pmh)  compliant  records  and  offers  the   user  the  opportunity  to  convert  those  records  to  a  variety  of  formats,  including  machine-­‐readable   cataloging  (marc),  machine-­‐readable  cataloguing  in  xml  (marc  xml),  metadata  object   description  schema  (mods),  and  encoded  archival  description  (ead).  it  also  offers  the   capabilities  of  converting  records  from  any  of  the  supported  formats  to  any  of  the  other  supported   formats.   other  examples  of  this  technique  are  the  web  services  editor-­‐converter  dublin  core  metadata  and   firefox  dublin  core  viewer  extension.  both  of  these  programs  search  html  files  on  the  web  and   convert  information  found  in  html  meta-­‐tags  to  dublin  core  elements.  in  the  cases  of  marcedit     information  technology  and  libraries  |  september  2015       26   and  editor-­‐converter  dublin  core,  users  are  presented  with  the  converted  information  in  an   interface  that  allows  the  user  to  edit  or  refine  the  data.     figure  1  provides  an  illustration  of  the  extracted  metadata  of  the  new  york  times  homepage  using   editor-­‐converter  dublin  core,  while  figure  2  offers  an  illustration  of  the  editor  that  this  web   service  provides.         figure  1.  screenshot  of

 this  type  of  tool  is  that  it  entirely  depends  on  the  quality  of  the   metadata  from  which  the  programs  harvest.  this  can  be  most  readily  seen  in  the  above  figure  by   the  lack  of  values  for  a  number  of  the  dublin  core  fields  for  the  the  new  york  times  website.   programs  that  solely  employ  the  technique  of  meta-­‐tag  harvesting  are  unable

 semi-­‐automatic  metadata  generation  tools|  park  and  brenza     doi:  10.6017/ital.v34i3.5889   29   content  extraction     content  extraction  is  a  form  of  metadata  extraction  whereby  various  computing  techniques  are   used  to  extract  information  from  the  information  resource  itself.  in  other  words,  these  techniques   do  not  rely  on  the  identification  of  relevant  meta-­‐tags  for  the  population  of  metadata  values.  an   example  of  this  technique  is  the  kea  application,  a  program  developed  at  the  new  zealand  digital   library  that  uses  machine  learning,  term  frequency-­‐inverse  document  frequency  (tf.idf)  and   first-­‐occurrence  techniques  to  identify  and  assign  key  phrases  from  the  full  text  of  documents.8   the  major  advantage  of  this  type  of  technique  is  that  the  extraction  of  metadata  can  be  done   independently  of  the  quality  of  metadata  associated  with  any  given  information  resource.  another   example  of  a  tool  utilizing  this  technique  is  the  open  text  summarizer,  an  open-­‐source  program   that  offers  the  capability  of  reading  a  text  and  extracting  important  sentences  to  create  a  summary   as  well  as  to  assign  keywords.  figure  3  provides  a  screenshot  of  what  a  summarized  text  might   look  like  using  the  open  text  summarizer.           figure  3.  open  text  summarizer:  sample  summary  of  text.   another  form  of  this  technique  often  relies  on  the  predictable  structure  of  certain  types  of   documents  to  identify  candidate  values  for  metadata  elements.  for  instance,  because  of  the   reliable  format  of  scholarly  research  papers—which  generally  include  a  title,  author,  abstract,   introduction,  conclusion,  and  reference  sections  in  predictable  ways—this  format  can  be  exploited   by  machines  to  extract  metadata  values  from  them.  several  projects  have  been  able  to  exploit  this   technique  in  combination  with  machine  learning  algorithms  to  extract  various  forms  of  metadata.     for  instance,  in  the  randkte  project,  optical  character  recognition  software  was  used  to  scan  a   large  quantity  of  legal  documents  from  which,  because  of  the  regularity  of  the  documents’     information  technology  and  libraries  |  september  2015       30   structure,  structural  metadata  such  as  chapter,  section,  and  page  number  could  be  extracted.9  in   contrast,

 fully  developed  for  application   within  real-­‐world  library  settings.  rather,  most  uses  of  these  techniques  have  been  developed  to   solve  the  problems  of  automatic  metadata  generation  within  the  context  of  specific  research   projects.       evaluation  of  semi-­‐automatic  metadata  generation  tools|  park  and  brenza     doi:  10.6017/ital.v34i3.5889   35   there  are  two  reasons  for  this.  one  is  that,  as  many  researchers  have  noted,  the  effectiveness  of   machine  learning  techniques  depends  on  the  quality  and  quantity  of  training  data  used  to  teach   the  system.13,  14,  15  because  of  the  number  and  diversity  of  subject  domains  as  well  as  the  shear   variety  of  document  formats,  many  applications  are  designed  to  address  the  metadata  needs  of   very  specific  subject  domains  and  very  specific  types  of  documents.  this  is  a  point  that  kovacevic   et  al.  make  in  stating  that  machine  learning  techniques  generally  work  best  for  documents  of  a   similar  type,  like  research  papers.16  another  issue,  especially  as  it  applies  to  automatic  indexing,  is   the  fact  that,  as  gardner  notes,  controlled  vocabularies  such  as  the  lcsh  are  too  complicated  and   diverse  in  structure  to  be  applied  through  semi-­‐automatic  means.17  although  some  open-­‐source   tools  such  as  data  fountains  have  made  efforts  to  overcome  this  complexity,  projects  like  it  are  the   exception  rather  than  the  rule.  these  issues  signify  the  difficulty  with  developing  sophisticated   semi-­‐automatic  metadata  generation  tools  that  have  general  applicability  across  a  wide  range  of   subject  domains  and  format  types.  nevertheless,  for  semi-­‐automatic  metadata  generation  tools  to   become  a  reality  for  the  library  community,  such  complexity  will  have  to  be  overcome.   there  are,  however,  some  tools  that  have  broader  applicability  or  can  be  customized  to  meet  local   needs.  for  instance,  the  kea  keyphrase  extractor  offers  the  option  of  building  local  or  applying   available  ontologies  that  can  be  used  to  refine  the  extraction  process.  perhaps  the  most  promising   of  all  is  the  above  mentioned  data  fountains  suite  of  tools  developed  by  the  university  of   california.  the  data  fountains  suite  incorporates  almost  every  one  of  the  semi-­‐automatic   metadata  techniques  described  in  this  study,  including  sophisticated  content  extraction  and   automatic  indexing  features.  it  also  provides  several  ways  to  customize  the  suite  in  order  to  meet   local  needs.     extrinsic  data  auto-­‐generation   extrinsic  data  auto-­‐generation  is  the  process  of  extracting  metadata  about  an  information   resource  that  is  not  contained  within  the  resource  itself.  extrinsic  data  auto-­‐generation  can   involve  the  extraction  of  technical  metadata  such  as  file  format  and  size  but  can  also  include  the   extraction  of  more  complicated  features  such  as  the  grade  level  of  an  educational  resource  or  the   intended  audience  for  a  document.  the  process  of  extracting  technical  metadata  is  perhaps  one   area  of  semi-­‐automatic  metadata  generation  that  is  in  a  high  state  of  development,  included  in   most  cmss  such  as  dspace,18  as  well  as  other  more  sophisticated  tools  such  as  harvard’s  jhove,   which  can  recognize  at  least  7twelve  different  kinds  of  textual,  audio,  and  visual  file  formats.19  on   the  other  hand,  the  problem  of  semi-­‐automatically  generating  other  types  of  extrinsic  metadata,   like  grade  level,  are  of  the  most  difficult  to  solve.     as  leibbrandt  et  al.  note  in  their

 auto-­‐generation.   social  tagging     social  tagging  is  now  a  familiar  form  of  subject  metadata  generation  although,  as  mentioned   previously,  it  is  not  properly  a  form  of  automatic  metadata  generation.  nevertheless,  because  of   the  relatively  low  cost  in  generating  and  maintaining  metadata  through  social  tagging  and  its   current  widespread  popularity,  a  few  projects  have  attempted  to  utilize  such  data  to  enhance   repositories.  for  instance,  linstaedt  et  al.  use  sophisticated  computer  programs  to  analyze  still   images  found  within  flickr  and  then  use  this  analysis  to  process  new  images  and  to  propagate   relevant  user  tags  to  those  images.21     in  a  slightly  more  complicated  example,  liu  and  qin  employ  machine-­‐learning  techniques  to   initially  process  and  assign  metadata,  including  subject  terms,  to  a  repository  of  documents   related  to  the  computer  science  profession.22  however,  this  proof  of  concept  project  also  permits   users  to  edit  the  fields  of  the  metadata  once  established.  the  user-­‐edited  tags  are  then   reprocessed  by  the  system  with  the  hope  of  improving  the  machine-­‐learning  mechanisms  of  the   database,  creating  a  kind  of  feedback  loop  for  the  system.  specifically,  the  improved  tags  are  used   by  the  system  to  suggest  and  assign  subject  terms  for  new  documents  as  well  as  to  improve   subject  description  of  existing  documents  within  the  repository.  although  these  two  examples   provide  instances  of  sophisticated  reprocessing  of  social  tag  metadata,  these  capabilities  do  not   seem  to  be  present  in  open-­‐source  tools  at  this  time.  nevertheless,  social  tagging  capabilities  are   offered  by  many  cmss  such  as  omeka.  these  social  tagging  capabilities  may  offer  a  means  to   enhance  subject  access  to  holdings.       information  technology  and  libraries  |  september  2015       38   table  5  below  lists  the  tools  that  support  social  tagging  either  as  the  sole

challenges  to  implementation   although  semi-­‐automatic  metadata  generation  tools  offer  many  benefits,  especially  in  regards  to   streamlining  the  metadata-­‐creation  process,  there  are  significant  barriers  to  the  widespread   adoption  and  implementation  of  these  tools.  one  problem  with  semi-­‐automatic  metadata   generation  tools  is  that  many  are  developed  locally  to  address  the  specific  needs  of  a  given  project   or  as  part  of  academic  research.  this  local,  highly  focused  milieu  for  development  means  that   general  applicability  of  the  tools  is  potentially  diminished.  the  local  context  may  also  hinder   widespread  adoption  of  applications  that  would  result  in  strong  communities  of  application  users   and  provide  further  support  for  the  development  of  applications  in  an  open-­‐source  context.   because  of  the  highly  specific  nature  of  many  current  tools,  their  relevance  to  real-­‐world   processes  of  metadata  creation  within  the  broader  context  of  libraries’  diverse  information   management  needs  are  not  accounted  for.   additionally,  many  tools  are  focused  on  solving  one  or,  at  most,  a  few  metadata  generation   problems.  for  instance,  the  kea  application  is  designed  to  use  machine-­‐learning  techniques  for  the   sole  purpose  of  extracting  keywords,  the  open  text  summarizer  is  limited  to  automatic   extractions  of  summary  descriptions  and  keywords,  and  editor  converter  dublin  core  is  designed   to  extract  information  in  html  meta-­‐tags  and  map  them  to  dublin  core  elements.  because  of  the   piecemeal  development  of  semi-­‐automatic  generation  tools,  any  comprehensive  package  of  tools   will  require  the  significant  efforts  of  the  implementer  to  coordinate  the  selected  applications  and   to  produce  results  in  a  single  output.  this  is,  to  say  the  least,  a  daunting  task.     furthermore,  a  high  degree  of  technical  skill  is  required  to  implement  these  complex  tools.  many   of  the  more  sophisticated  tools  used  to  semi-­‐automatically  generate  metadata,  such  as  data   fountains,  kea,  and  apache  stanbol,  require  competence  in  a  variety  of  programming  languages.     evaluation  of  semi-­‐automatic  metadata  generation  tools|  park  and  brenza     doi:  10.6017/ital.v34i3.5889   39   significant  knowledge  of  c++,  python,  and  java,  are  required  to  implement  these  systems  properly.   the  high  degree  of  technical  knowledge  needed  to  implement  these  tools  means  that  many   libraries  and  other  institutions  may  not  have  resources  to  begin  implementing  them,  let  alone   incorporating  them  into  the  daily  workflows  of  the  metadata  creation  process.  further,  this  high   degree  of  technical  expertise  may  require  libraries  to  seek  assistance  outside  of  the  library.  in   other  words,  librarians  may  need  to  build  strong  collaborative  relationships  with  those  who  have   the  technical  skills,  expertise  and  credentials  to  implement  and  maintain  these  complicated  tools.   as  vellucci  et  al.  note  in  regards  to  their  development  of  the  metadata  education  and  research   information  commons  (meric),  a  metadata-­‐driven  clearinghouse  of  education  materials  related   to  metadata,  elaborate  and  multidisciplinary  partnerships  need  to  be  firmly  established  for  the   ultimate  success  of  such  projects,  including  the  sustained  support  of  the  highest  levels  of   administration.23  these  types  of  partnerships  may  be  difficult  to  establish  and  maintain  for  the   sustained  implementation  of  complicated  tools.     additionally,  sustainable  development  of  tools,  especially  in  regards  to  the  funding  needed  for   continued  development  of  open-­‐source  applications,  appears  to  be  a  significant  barrier  to   implementation.  for  instance,  at  the  time  of  this  writing,  many  of  the  tools  that  were  touted  in  the   literature  as  being  most  promising,  such  as  dc  dot,  reggie,  and  describethis,  are  no  longer   available  for  implementation.  beyond  the  fact  that  discontinuation  hurts  the  potential  adoption   and  continued  development  of  semi-­‐automatic  tools  within  real  world  library  and  other   information  settings,  there  is  also  the  problem  that  those  settings  that  have  in  fact  adopted  tools   may  lose  the  technical  support  of  a  central  developer  and  community  of  users.  thus   discontinuation  may  result  in  higher  rates  of  tool  obsolescence  and  increase  the  potential   expenses  of  libraries  who  have  implemented  and  then  must  change  applications.   finally,  the  application  of  semi-­‐automatic  metadata  tools  remains  relatively  untested  in  real-­‐world   scenarios.  as  polfreman  et  al.  note,  most  tests  of  automatic  metadata  generation  tools  have  several   of  problems,  including  small  sample  sizes,  narrow  scope  of  project  domains,  and  experiments  that   lack  true  objectivity  because  systems  are  generally  tested  by  their  creators.24  for  these  reasons,   libraries  and  other  institutions  may  be  reluctant  to  expand  the  resources  needed  to  implement   and  fully  integrate  a  complicated,  promising,  but  ultimately  untested,  tool  within  the  already   strained  workflows  of  its  processes.     conclusion   semi-­‐automatic  metadata  generation  tools  hold  the  promise  of  assisting  information  professionals   with  the  management  of  ever-­‐increasing  quantities  and  types  of  information  resources.  using   software  that  can  create  metadata  records  consistently  and  efficiently,  semi-­‐automatic  metadata   generation  tools  potentially  offer  significant  cost  and  time  savings.  however,  the  full  integration  of   these  tools  into  the  daily  workflows  of  libraries  and  other  information  settings  remains  elusive.   for  instance,  although  many  tools  have  been  developed  that  have  addressed  many  of  the  more   complicated  aspects  of  semi-­‐automatic  metadata  generation,  including  the  extraction  of     information  technology  and  libraries  |  september  2015       40   information  related  to  conceptually  difficult  areas  of  bibliographic  description  such  as  subject   terms,  open-­‐ended  resource  descriptions,  and  keyword  assignment,  many  of  these  tools  are   relevant  only  at  the  project  level  and  are  not  applicable  to  the  broader  contexts  needed  by   libraries.  in  other  words,  the  current  array  of  tools  exists  to  solve  experimental  problems  but  has   not  been  developed  to  the  point  that  the  library  community  can  implement  it  in  a  meaningful  way.     perhaps  the  greatest  area  of  difficulty  lies  in  the  fact  that  most  tools  only  address  part  of  the   problem  of  semi-­‐automatic  metadata  generation,  providing  solutions  to  the  semi-­‐automatic   generation  of  one  or  a  few  bibliographic  elements  but  not  the  full  range  elements.  this  means  that   for  libraries  to  truly  have  a  comprehensive  tool  set  for  the  semi-­‐automatic  generation  of  metadata   records,  significant  local  efforts  will  be  required  to  integrate  the  various  tools  into  a  working   whole.  couple  this  issue  with  the  instability  of  tool  development  and  maintenance  and  it  appears   that  the  library  community  may  lack  incentive  to  invest  already  strained  and  limited  resources  in   the  adoption  of  these  tools.   thus  it  appears  that  a  number  of  steps  will  need  to  be  taken  before  the  library  community  can   seriously  consider  the  incorporation  of  semi-­‐automatic  metadata  generation  tools  within  its  daily   workflows.  first,  it  seems  that  the  integration  of  these  various  tools  into  a  coherent  set  of   applications  is  likely  the  next  step  in  the  development  of  viable  semi-­‐automatic  metadata   generation.  since  most  small  libraries  likely  do  not  have  the  resources  required  to  integrate  these   disparate  tools  together,  let  alone  incorporate  them  within  existing  library  systems,  a  single   package  of  tools  will  be  needed  simply  from  a  resource  perspective.  secondly,  considering  the  high   level  of  technical  expertise  needed  to  implement  the  current  array  of  tools,  the  integrated  set  of   tools  must  be  accomplished  in  such  a  way  as  to  foster  implementation,  utilization,  and   maintenance  with  a  minimum  of  technical  expertise.  for  instance,  if  an  integrated  set  of  tools  that   functioned  across  a  wide  range  of  subject  domains  and  format  types  could  be  developed,  the  suite   might  be  akin  to  the  cmss  currently  employed  by  many  libraries.  furthermore,  with  a  suite  of   tools  that  are  relatively  easy  to  use,  adaption  would  likely  increase.  this  might  result  in  a  stable   community  of  users  that  would  foster  the  further  development  of  the  tools  in  a  sustainable   manner.  a  comprehensive,  relatively  easy  to  implement  set  of  tools  might  foster  independent   testing  of  those  tools.  the  independent  testing  of  the  semi-­‐automatic  tools  is  needed  to  provide  an   objective  basis  for  tool  evaluation  and  further  development.   finally,  designing  automated  workflows  tailored  to  the  subject  domain  and  types  of  resources   seems  to  be  an  essential  step  for  integrating  semi-­‐automatic  metadata  generation  tools  into   metadata  creation.  such  workflows  may  delineate  data  elements  that  can  be  generated  by   automated  meta-­‐tag  extractor  from  data  elements  that  need  to  be  refined  and  manually  created  by   cataloging  and  metadata  professionals.  to  develop,  maximize,  and  sustain  semi-­‐automatic   metadata  generation  workflows,  administrative  support  for  finance,  human  resources,  and   training  is  critical.       evaluation  of  semi-­‐automatic  metadata  generation  tools|  park  and  brenza     doi:  10.6017/ital.v34i3.5889   41   thus,  although  many  of  the  technical  aspects  of  semi-­‐automatic  metadata  generation  are  well  on   their  way  to  being  solved,  many  other  barriers  exist  that  might  limit  adoption.  further,  these   barriers  may  have  a  negative  influence  on  the  continued,  sustainable  development  of  semi-­‐ automatic  metadata  generation  tools.  nevertheless,  there  is  a  critical  need  that  the  library   community  finds  ways  to  manage  the  recent  explosion  of  data  and  information  in  cost-­‐effective   and  efficient  ways.  semi-­‐automatic  metadata  generation  holds  the  promise  to  do  just  that.     acknowledgement

example from portland state university kimberly d. pendell and michael s. bowman usability study of a library’s mobile website | pendell and bowman 45 abstract to discover how a newly developed library mobile website performed across a variety of devices, the authors used a hybrid field and laboratory methodology to conduct a usability test of the website. twelve student participants were recruited and selected according to phone type. results revealed a wide array of errors attributed to site design, wireless network connections, as well as phone hardware and software. this study provides an example methodology for testing library mobile websites, identifies issues associated with mobile websites, and provides recommendations for improving the user experience. introduction mobile websites are swiftly becoming a new access point for library services and resources. these websites are significantly different from full websites, particularly in terms of the user interface and available mobile-friendly functions. in addition, users interact with a mobile website on a variety of smartphones or other internet-capable mobile devices, all with differing hardware and software. it is commonly considered a best practice to perform usability tests prior to the launch of a new website in order to assess its user friendliness, yet examples of applying this practice to new library mobile websites are rare. considering the variability of user experiences in the mobile environment, usability testing of mobile websites is an important step in the development process. this study is an example of how usability testing may be performed on a library mobile website. the results provided us with new insights on the experience of our target users. in the fall of 2010, with the rapid growth of smartphones nationwide especially among college students, portland state university (psu) library decided to develop a mobile library website for its campus community. the library’s lead programmer and a student employee developed a test version of the website. this version of the website included library hours, location information, a local catalog search, library account access for viewing and renewing checked out items, and access to reference services. it also included a “find a computer” feature displaying the availability of work stations in the library’s two computer labs. kimberly d. pendell (kpendell@pdx.edu) is social sciences librarian, assistant professor, and michael s. bowman (bowman@pdx.edu) is interim assistant university librarian for public services, associate professor, portland state university library, portland, oregon. mailto:kpendell@pdx.edu mailto:bowman@pdx.edu information technology & libraries | june 2012 46 the basic architecture and design of the site was modeled on other existing academic library mobile websites that were appealing to the development team. the top-level navigation of the mobile website largely mirrored the full library website, utilizing the same language as the website when possible. the mobile website was built to be compatible with webkit, the dominant smartphone layout engine. use of javascript on the website was minimized due to the varying levels of support for it on different smartphones, and flash was avoided entirely. figure 1. home page of library mobile website, test version we formed a mobile website team to further evaluate the test website and prepare it for launch. three out of four team members owned smartphones, either an iphone 3gs or an iphone 4. we soon began questioning how the mobile website would work on other types of phones, recognizing that hardware and software differences would likely impact user experience of the mobile website. performing a formal usability test using a variety of internet-capable phones quickly became a priority. we decided to conduct a usability test for the new mobile website in order to answer the question: how user-friendly and effective is the new library mobile website on students’ various mobile devices? literature review smartphones, mobile websites, and mobile applications have dominated the technology landscape in the last few years. smartphone ownership has steadily increased, and a large percentage of usability study of a library’s mobile website | pendell and bowman 47 smartphone owners regularly use their phone to access the internet. the pew research center reports that 52 percent of americans aged 18–29 own smartphones, and 81 percent of this population use their smartphone to access the internet or e-mail on a typical day. additionally, 42 percent of this population uses a smartphone as their primary online access point.1 the 2010 ecar study of undergraduate students and information technology found that 62.7 percent of undergraduate students own internet-capable handheld devices, an increase of 11.5 percent from 2009. the 2010 survey also showed that an additional 11.3 percent of students intended to purchase an internet-capable handheld device within the next year.2 in this environment academic libraries have been scrambling to address the proliferation of student owned mobile devices, thus the number of mobile library websites is growing. the library success wiki, which tracks libraries with mobile websites, shows an 66 percent increase in the number of academic libraries in the united states and canada with mobile websites from august 2010 to august 2011.3 we reviewed articles about mobile websites in the professional library science literature and found that mobile website usability testing is only briefly mentioned. in their summary of current mobile technologies and mobile library website development, bridges, rempel, and griggs state that “user testing should be part of any web application development plan. you can apply the same types of evaluation techniques used in non-mobile applications to ensure a usable interface.”4 in a previous article, the same authors also note that not accounting for other types of mobile users is easy to do but leaves a potentially large audience for a mobile website “out in the cold.”5 more recently, seeholzer and salem found the usability aspect of mobile website development to be in need of further research.6 usability evaluation techniques for a mobile website are similar to those for a full website, but the variety of smartphones and internet-capable feature phones immediately complicates standard usability testing practices. the mobile device landscape is fraught with variables that can have a significant impact on the user experience of a mobile website. factors like small screen size, processing power, wireless or data plan connection, and on-screen keyboards or other data entry methods contribute to user experience and impact usability testing. zhang and adipat note that, mobile devices themselves, due to their unique, heterogeneous characteristics and physical constraints, may play a much more influential role in usability testing of mobile applications than desktop computers do in usability testing of desktop applications. therefore real mobile devices should be used whenever possible.7 one strategy for usability testing on mobile devices is to identify device “families” by similar operating systems or other characteristics, then perform a test of the website. for example, griggs, bridges, and rempel found representative models of device families at a local retailer, where they tested the site on the display phones. the authors also recommend “hallway usability testing,” an impromptu test with a volunteer.8 zhang and adipat go on to outline two methodologies for formal mobile application usability testing: field studies and laboratory experiments. the benefit of a mobile usability field study is information technology & libraries | june 2012 48 the preservation of the mobile environment in which tasks are normally performed. however, data collection is challenging in field studies, requiring the participant to reliably and consistently selfreport data. in contrast, the benefit of a laboratory study is that researchers have more control over the test session and data collection method. laboratory usability tests lend themselves to screen capture or video recording, allowing researchers more comprehensive data regarding the participant’s performance on predetermined tasks.9 however, billi and others point out that there is no general agreement in the literature about the significance or usefulness of the difference between laboratory and field testing of mobile applications.10 one compromise between field studies and laboratory experiments is the use of a smartphone emulator: an emulator mimics the smartphone interface on a desktop computer and is recordable via screen capture. however, desktop emulators mask some usability problems that impact smartphones, such as an unstable wireless connection or limited bandwidth.11 in order to record test sessions of users working directly with mobile devices, jakob nielsen, the well-known usability expert, briefly mentions the use of a document camera.12 in another usability test of a mobile application, loizides and buchanan also used a document camera with recording capabilities to effectively record users working with a mobile device.13 usability attributes are metrics that help assess the user-friendliness of a website. in their review of empirical mobile usability studies, coursaris and kim present the three most commonly used measures in mobile usability testing: efficiency: degree to which the product is enabling the tasks to be performed in a quick, effective and economical manner or is hindering performance; effectiveness: accuracy and completeness with which specified users achieved specified goals in particular environment; satisfaction: the degree to which a product is giving contentment or making the user satisfied.14 the authors present these measures in an overall framework of “contextual usability” constructed with the four variables of user, task, environment, and technology. an important note is the authors’ use of technology rather than focusing solely on the product; this subtle difference acknowledges that the user interacts not only with a product, but also other factors closely associated with the product, such as wireless connectivity.15 a participant proceeding through a predetermined task scenario is helpful in assessing site efficiency and effectiveness by measuring the error rate and time spent on a task. user satisfaction may be gauged by the participant’s expression of satisfaction, confusion, or frustration while performing the tasks. measurement of user satisfaction may also be supplemented by a post-test survey. returning to general evaluation techniques, mobile website usability employs the use of task scenarios, post-test surveys, and data analysis methods, similar to full site testing. general guides such as the handbook of usability testing by rubin and chisnell and george’s user-centered library websites: usability evaluation methods provide helpful information on designing task scenarios, how to facilitate a test, post-test survey ideas, and methods of analysis.16 another usability study of a library’s mobile website | pendell and bowman 49 common data collection method in usability testing is the think aloud protocol as it allows researchers to more fully understand the user experience. participants are instructed to talk about what they are thinking as they use the site; for example, expressing uncertainty of what option to select, frustration with poorly designed data entry fields, or satisfaction with easily understood navigation. examples of the think aloud protocol can also be found in mobile website usability testing.17 method while effective usability testing normally relies on five to eight participants, we decided a larger number of participants would be needed in order to capture the behavior of the site on a variety of devices. therefore, we recruited twelve participants to accommodate a balanced variety of smartphone brands and models. based on average market share, we aimed to test the website on four iphones, four android phones, and four other types of smartphones or internet-capable mobile devices (e.g., blackberry, windows phones). all study participants were university students, the primary target audience of the mobile website. we used three methods to recruit participants: a post to the library’s facebook page, a news item on the library’s home page, and two dozen flyers posted around campus. each form of recruitment described an opportunity for students to spend less than thirty minutes helping the library test its new mobile website. also, participants would receive a $10 coffee shop gift card as an incentive. a project-specific email address served as the initial contact point for students to volunteer. we instructed volunteers to indicate their phone type in their e-mail; this information was used to select and contact the students with the desired variety of mobile devices. if a scheduled participant did not come to the test appointment, another student with the same or similar type of phone was contacted and scheduled. no other demographic data or screening was used to select participants, aside from a minimum age requirement of eighteen years old. we employed a hybrid field and laboratory test protocol, which allowed us to test the mobile website on students’ native devices while in a laboratory setting that we could efficiently manage and schedule. participants used their own phone for the test without any adjustment to their existing operating preferences, similar to field testing methodology. however, we used a controlled environment in order to facilitate the test session and create recordings for data analysis. a library conference room served as our laboratory, and a document camera with video recording capability was used to record the session. the document camera was placed on an audio/visual cart and the participants chose to either stand or sit while holding their phones under the camera. the document camera recorded the phone screen, the participant’s hands, and the audio of the session. the video feed was available through the room projector as well, which helped us monitor image quality of the recordings. information technology & libraries | june 2012 50 figure 2. video still from test session recording the test session consisted of two parts: the completion of five tasks using participants’ phones on our test website recorded under the document camera, and a post-test survey. participants were read an introduction and instructions from a script in order to decrease variation in test protocol and our influence as the facilitators. we also performed a walk-through of the testing session prior to administering it to ensure the script was clearly worded and easy to understand. we developed our test scenarios and tasks according to five functional objectives for the library mobile website: 1. participants can find library hours for a given day in the week. 2. participants can perform a known title search in catalog and check for item status. 3. participants can use my account to view checked out books.18 4. participants can use chat reference. 5. participants can effectively search for a scholarly article using the mobile version of ebscohost academic search complete. prior to beginning the test, we encouraged participants to use the “think aloud” protocol while performing tasks. we also instructed them to move between tasks however they would naturally in order to capture user behavior when navigating from one part of the site to another. the post-test survey provided us with additional data and user reactions to the site. users were asked to rate the site’s appearance, ease of use, and how frequently they might use the different website features usability study of a library’s mobile website | pendell and bowman 51 (e.g., renewing a checked out item). the survey was administered directly after the task scenario portion of the test in order to take advantage of the users’ recent experience with the website. we evaluated the test sessions utilizing the measures of efficiency, effectiveness, and satisfaction. in this study, we assessed efficiency as time spent performing the task and effectiveness as success or failure in completing the task. we observed errors and categorized them as either a user error or site error. each error was also categorized as minor, major, or fatal: minor errors were easily identified and corrected by the user; major errors caused a notable delay, but the user was able to correct and complete the task; fatal errors prevented the user from completing the task. to assess user satisfaction, we took note of user comments as they performed tasks, and we also referred to their ratings and comments on the post-test survey. before analyzing the test recordings, we normalized our scoring behavior by performing a sample test session with a library staff member unfamiliar with the mobile website. we scored the sample recording separately and then met to discuss, clarify, and agree upon each error category. each of the twelve test sessions was viewed and scored independently. once this process was completed, we discussed our scoring of each test session video, combining our data and observations. we analyzed the combined data by looking for both common and unique errors for each usability task across the variety of smartphones tested. to protect participants’ confidentiality, each video file and post-test survey was labeled only with the test number and device type. prior to beginning the study, all recruitment methods, informed consent, methodology, tasks and post-test survey were approved by portland state university human subjects research and review committee. findings our recruitment efforts were successful with even a few same-day responses from the announcement posted on the library’s facebook page. some students also indicated that they had seen the recruitment flyers on campus. a total of fifty-two students volunteered to participate; twelve students were successfully contacted, scheduled, and tested. the distribution of the twelve participants and their types of phones is shown in table 1. number of participants operating system phone model 4 android htc droid incredible 2; motorola droid; htc mytouch 3g slide; motorola cliq 2 3 ios iphone 3gs 2 blackberry blackberry 9630; blackberry curve

test participants by smartphone operating system and model usability task scenarios all test participants quickly and successfully completed the first task, finding the library hours for sunday. the second task was to find a book in the library catalog and report whether the book was available for check out. nine participants completed this task; the windows phone 7 and the two blackberry phones presented a fatal system error when working with our mobile catalog software, mobilecat. these participants were able to perform a search but were not able to view a full item record, blocking them from seeing the item’s availability and completing the task. this task also revealed one minor error for iphone users: the iphone displayed the item’s ten digit isbn as a phone number, complete with touch-to-call button. many users took more time than anticipated when asked to search for a book. the video recordings captured participants slowly scrolling through the menu before choosing “search psuonly catalog.” a few participants expressed their hesitation verbally: ● “maybe not the catalog? i don't know. yeah i guess that would be the one.” ● “i don't look for books on this site anyway...my lack of knowledge more than anything else.” ● “search psu library catalog i'm assuming?” the blackberry curve participant did not recognize the catalog option and selected “databases & articles” to search for a book. she was guided back to the catalog after her unsuccessful search in ebscohost. we observed an additional delay in searching for a book when using the catalog interface. the catalog search included a pull down menu of collections options. the collections menu was included by the site developers because it is present in the full website version of the local catalog. users tended to explore the menu looking for a selection that would be helpful in performing the task; however, they abandoned the menu, occasionally expressing additional confusion. usability study of a library’s mobile website | pendell and bowman 53 figure 3. catalog search with additional “collections” menu the next task was to log into a library account and view checked out items. all participants were successful with this task, but frequent minor user errors were observed, all misspelling or numerical entry errors. most participants self-corrected before submitting the login; however, one participant submitted a misspelled user name and promptly received an error message from the site. participants were also instructed to log out of the account. after clicking “logout” one participant made the observation; “huh, it goes to the login screen. i assume i'm logged out, though it doesn't say so.” the fourth task scenario involved using the library’s chat reference service via the mobile website. the chat reference service is provided via open source software in cooperation with l-net, the oregon statewide service. usability testing demonstrated that the chat reference service did not perform well on a variety of phones. also, a significant problem arose when participants attempted to access chat reference via the university’s unsecured wireless network. because the chat reference service is managed by a third-party host, three participants were confronted with a non-mobile friendly authentication screen (see discussion of the local wireless environment below). as this was an unexpected event in testing, participants were given the option to authenticate or abandon the task. all three participants who arrived at this point chose to move ahead with authentication during the test session. information technology & libraries | june 2012 54 once the chat interface was available to participants, other system errors were discovered. only three out of twelve participants successfully sent and received a chat message. only one participant (htc droid incredible) experienced an error-free chat transaction. various problems encountered included: · unresponsive or slow to respond buttons, · text fields unresponsive to data entry, · unusually long page loading time, · non-mobile-friendly error message upon attempting to exit, and · non-mobile-friendly “leave a message” webpage. another finding from this task is that participants expressed concern regarding communication delays during the chat reference task. if the librarians staffing the chat service are busy with other users, a new incoming user is placed in a queue. after waiting in the chat queue for forty seconds, one participant commented, “probably if i was on the bus and it took this long, i would leave a message.” being in a controlled environment, participants looked to the facilitator as a guide for how long to remain in the chat queue, distorting the indication of how long users would wait for a chat reference transaction in the field environment. figure 4. chat reference queue usability study of a library’s mobile website | pendell and bowman 55 the last task scenario asked participants to use the mobile version of ebscohost’s academic search complete. our test instance of this database generally performed well with android phones and less well with webos phones or iphones. android participants successfully accessed, searched, and viewed results in the database. iphone users experienced delays in initiating text entry, three consecutive touches being consistently necessary to activate typing in the search field. our feature phone participant with a windows kin 2 was unable to use ebscohost because the phone’s browser, internet explorer 6, is not supported by the ebscohost mobile website. the palm pixi participant also experienced difficulty with very long page loading times, two security certificate notifications (not present on other tests), and our ezproxy authentication page. with all these obstacles, the palm pixi participant abandoned the task. another participant, blackberry 9630, also abandoned the task due to slow page loading. a secondary objective of our ebscohost search task was to observe if participants explored ebscohost’s “search options” in order to limit results to scholarly articles. our task scenario asked participants to find a scholarly article on global warming. only one participant explored the ebscohost interface, successfully identified the “search options” menu, and limited the results to “scholarly (peer reviewed) articles.” another participant included the words “peer reviewed” with “global warming” in the search field in an attempt to add the limit. a third expressed the need to limit to scholarly articles but was unable to discover how to do so. of the remaining seven participants who searched academic search complete for the topic “global warming” none expressed concern or awareness of the scholarly limit in academic search complete. it is unclear whether this was a product of the interface design, users’ lack of knowledge regarding limiting their search to scholarly sources, or if our task scenario was simply too vague. though participants’ wireless configurations, or lack thereof, was not formally part of the usability test, we quickly discovered that this variable had a significant impact on the user’s experience of the mobile website. in the introductory script and informed consent we recommended to participants that they connect to the university’s wireless network to avoid data charges. however, we did not explicitly instruct users to connect to the secure network. most participants chose to connect to the unencrypted wireless network and appeared to be unaware of the encrypted network (psu and psu secure respectively). using the unencrypted network led to authentication requirements at two different points in the test: using the chat service and searching academic search complete. other users who were unfamiliar with adding a wireless network to their phone used their cellular network connection. these participants were asked to authenticate only when accessing ebscohost’s academic search complete (see table 2). participants expressed surprise at the appearance of an authentication request when performing different tasks, particularly while connected to the on-campus university wireless network. the required data entry in a non-mobile friendly authentication screen, and the added page loading time, created an obstacle for the participant to overcome in order to complete the task. notably, three participants also explained their naivete on how to find and add a wireless network to their phone.

internet connection and resource. post -test survey each participant completed a post-test survey that asked them to rate the mobile website’s appearance and ease of use. the survey also asked participants to rank how frequently they were likely to use specific features of the website such as search for books and ask for help on a rating scale of more than weekly, weekly, monthly, less than monthly, and never. participants were also invited to add general comments about the website. the mobile website’s overall appearance and ease of use was highly rated by all participants. the straightforward design of the mobile website’s homepage also garnered praise in the comment section of the post-test survey. comments regarding the site’s design included: “very simple to navigate,” and “the simple homepage is perfect! also, i love that the site rotates sideways with my phone.” for many of the features listed on the survey participants selected an almost even distribution across the frequency of use rating scale. however, two features were ranked as having potential for very high use. nine out of twelve participants said they would search for articles weekly or more than weekly. eight out of twelve participants said they would use the “find a computer” function weekly or more than weekly. two participants additionally wrote in comments that “find a computer” was “very important” and would be used “every day.” at the other end of the scale, our menu option “directions” was ranked as having a potential frequency of use of never, with the exception of one participant marking less than monthly. discussion usability testing of the library’s mobile website provided the team with valuable information, leading us to implement important changes before the site was launched. we quickly decided on a usability study of a library’s mobile website | pendell and bowman 57 few changes, while others involved longer discussion. the collections menu was removed from the catalog search; this menu distracted and confused users with options that were not useful in a general search. “directions” was moved from a top level navigation element to a clickable link in the site footer. also, the need for a mobile version of the library’s ezproxy authentication page was clearly documented and has since been created and implemented. however, the team was very pleased with the praise for the overall appearance of the website and its ease of use, especially considering the significant difficulties some participants faced when completing specific tasks. the “find a computer” feature of the mobile website was very popular with test participants. the potential popularity among users is perhaps a reflection of overcrowded computer labs across campus and the continued need students have for desktop computing. unfortunately, “find a computer” has been temporarily removed from the site due to changes in computer laboratory tracking software at the campus it level. we hope to soon again have access to the workstation data for the library’s two computer labs in order to develop a new version of this feature. the hesitation participants displayed when selecting the catalog option in order to search for a book was remarkable for its pervasiveness. it’s possible that the term “catalog” has declined in use to the point of not being recognizable to some users, and it is not used to describe the search on the homepage of the library’s full website. in fact, we had originally planned to name the catalog search option with a more active and descriptive phrase, such as “find books and more,” which is used on the library’s full website. however, the full library website employs worldcat local, allowing users to make consortial and interlibrary loan requests. in contrast, the mobile website catalog reflects only our local holdings and does not support the request functionality. the team decided not to potentially confuse users further regarding the functionality of the different catalogs by giving them the same descriptive title. in the case that worldcat local’s beta mobile catalog increases in stability and functionality, we will abandon mobilecat and provide the same request options on the mobile website as on the full website. we discussed removing the chat service option from the “ask us” page. during usability testing, it was demonstrated that users would too frequently have poor experiences using this service due to slow page loads on most phones, the unpredictable responsiveness of text entry fields and buttons, and the wait time for a librarian to begin the chat. also, it could be that waiting in a virtual queue on a mobile device is particularly unappealing because the user is blocked from completing other tasks simultaneously. the library recently implemented a new text reference service, and this service was added to the mobile website. the text reference service is an asynchronous, non-webbased service that is less likely to pose similar usability problems as those found with the chat service. this reflects the difference between applications developed for desktop computing, such as web-based instant messaging, versus a technology that is specifically related to the mobile phone environment, like text messaging. however, tablet device users complicate matters since they might use the full desktop website or the mobile website; for this reason, chat reference is still part of the mobile website. information technology & libraries | june 2012 58 participants’ interest in accessing and searching databases was notable. during the task, many participants expressed positive reactions to the availability of the ebscohost database. the posttest survey results demonstrated a strong interest in searching for articles via the mobile website, giving their potential frequency of use as weekly or more than weekly. this evidence supports the previous user focus group results of seeholzer and salem.19 students are interested in accessing research databases on their mobile devices, despite the likely limitations of performing advanced searches and downloading files. therefore, the team decided to include ebscohost’s academic search complete along with eight other mobile-friendly databases in the live version of the website launched after the usability test. figure 5. home page of the library mobile website, updated usability study of a library’s mobile website | pendell and bowman 59 the new library mobile website was launched in the first week of fall 2011 quarter classes. in the first full week there were 569 visits to the site. site analytics for the first week also showed that our distribution of smartphone models in usability testing was fairly well matched with the users of the website, though we underestimated the number of iphone users: 64 percent of visits were from apple ios users, 28 percent from android users, 0.7percent blackberry users, and the remaining a mix of users with alternative mobile browsers and desktop browsers. usability testing with participants’ native smartphones and wireless connectivity revealed issues which would have been absent in a laboratory test that employed a mobile device emulator and a stable network connection. the complications introduced by the encrypted and unencrypted campus wireless networks, and cellular network connections, revealed some of the many variables users might experience outside of a controlled setting. ultimately, the variety of options for connecting to the internet from a smartphone, in combination with the authentication requirements of licensed library resources, potentially adds obstacles for users. general recommendations for mobile library websites that emerged from our usability test include: · users appreciate simple, streamlined navigation and clearly worded labels; · error message pages and other supplemental pages linked from the mobile website pages should be identified and mobile-friendly versions created; · recognize that how users connect to the mobile website is related to their experience using the site; · anticipate problems with third-party services (which often cannot be solved locally). additionally, system responses to user actions are important; for example, provide a “you have successfully logged out” message and an indicator that a catalog search is in progress. it is possible that users are even more likely to abandon tasks in a mobile environment than in a desktop environment if they perceive the site to be unresponsive. as test facilitators, we experienced three primary difficulties in keeping the testing sessions consistent. the unexpectedly poor performance of the mobile website on some devices required us to communicate with participants about when a task could be abandoned. for example, after one participant made three unsuccessful attempts at entering text data in the chat service interface, she was directed to move ahead to the next task. such instances of multiple unsuccessful attempts were considered to be fatal system errors. however, under these circumstances, it is difficult to know whether our test facilitation led participants to spend more or less time than they normally would attempting a task. secondly, the issue of system authentication led to unexpected variation in testing. some participants proceeded through these obstacles, while others either opted out or had significant enough technical difficulties that the task was deemed a fatal error. again, it is unclear how the average user would deal with this situation in the field. some users information technology & libraries | june 2012 60 might leave an activity if an obstacle appears too cumbersome, others might proceed. finally, participants demonstrated a wide range in their willingness to “think aloud.” in retrospect, as facilitators, we should have provided an example of the method before beginning the test; perhaps doing so would have encouraged the participants to speak more freely. the relatively simple nature of most of the test tasks may have also contributed to this problem as participants seemed reluctant to say something that might be considered too obvious. another limitation of our study is that the participants were a convenience sample of volunteers selected by phone type. though our selection was based loosely on market share of different smartphone brands, a preliminary investigation into the mobile device market of our target population would have been helpful to establish what devices would be most important to test. additional usability testing on more complex library related tasks, such as advanced searching in a database, or downloading and viewing files, is recommended for further research. also of interest would be a study of user willingness to proceed past obstacles like authentication requirements and non-mobile friendly pages in the field. conclusion we began our study questioning whether or not different smartphone hardware and operating systems would impact the user experience of our library’s new mobile website. usability testing confirmed that the type of smartphone does have an impact on the user experience, occasionally significantly so. by testing the site on a range of devices, we observed a wide variation of successful and unsuccessful experiences with our mobile website. the wide variety of phones and mobile devices in use makes developing a mobile website that perfectly serves all of them difficult; there is likely to always be a segment of users who experience difficulties with any given mobile website. however, usability testing data and developer awareness of potential problems will generate positive changes to mobile websites and alleviate frustration for many users down the road. references and notes 1. aaron smith, “35% of american adults own a smartphone: one quarter of

cynthia porter information technology and libraries | september 2012 2 the future looks exciting for ital, with our new open access and online only journal. as i look forward, i have been thinking about librarians and the changes i have witnessed in library technology. i would like to thank judith carter for her work on ital for over 13 years. she encouraged me to volunteer for the editorial board. i will miss her. i believe that lessons from the past can help us. ital’s first issue appeared in 1982—the same year that i graduated from high school. i typed all my school papers with a typewriter except for my last couple of papers in college. my father bought an early macintosh computer (called lisa). he had a daisy wheel printer—if we wanted to change fonts, we changed out the daisy wheel. i am thankful for the editing capabilities and font choices i have now when i create documents. as an undergraduate student, i worked on dedicated oclc terminals in the interlibrary loan (ill) department at my college library. i was hired because i had the two hours open when ill usually used mail. i thought our ill service was a big help for our students. i could not imagine then that electronic copies of articles could be delivered to ill customers within one day. today’s ill staff doesn’t have to worry about paper cuts now, either. i graduated from library school in 1989. when i first started working as a cataloger, we were able to access oclc on pc’s (an improvement from the dumb terminals) in the libraries. our subject heading lists were in the big red books from the library of congress. i tried to use the red books as an example for today’s students and they had no idea what i was talking about. even though “subject headings” are a foreign concept to many students today, i will always value them and fight for their continuation. i worked on several retrospective conversion projects when i worked for a library contractor until 1991. the libraries still had card catalogs and we converted these physical catalogs to online catalogs. nicholson baker’s article “discards1,” published in 1994, fondly remembered card catalogs. this article was discussed fervently in library school, but it seems quaint now. i grew up with card catalogs and i liked being able to browse through the subject listings. browsing online does not provide the same satisfaction, but i would never give up the ability to keyword search an electronic document. i liked browsing the classification schemes, too. i did like easily seeing where your chosen number appeared within the scheme. it’s harder to do the same thing online. in 1991 i worked at an academic library where we were still converting catalog cards. we all had cynthia porter (cporter@atsu.edu) is distance support librarian at a.t. still university of health sciences, mesa, arizona. editorial board thoughts: appreciation for history| porter 3 computers on our desks by then and we were comfortable with regular use of e-mail. the internet was still young and gophers were the new technology. even though gophers were text-based, i thought it was amazing how easy it was to access information from a university on the other side of the country. the internet was the biggest technology development for me. i currently work with distance students who rely on their internet connections to use our online library. i could not imagine even having distance students if we weren’t connected with computers as we are now. a 2009 issue of ital was dedicated to discovery tools. in judith carter’s introduction to the issue she cites the browsing theory of shan-ju lin chang. browsing is an old practice in libraries and i am very happy to see that discovery tools use this classic library practice. bringing like items together has been a helpful organization method for ages. when i studied s.r. ranganathan and his colon classification scheme, i realized that faceted classification would work very well on the web. i found his ideas to be fascinating, but difficult to implement on book labels for classification numbers. some discovery tools even identify “facets” in searching and limiting. ranganathan’s work is a beautiful example of an old idea blossoming years after its conception. classification, facets, and browsing are old ideas that are still helping us organize information in our libraries. we can’t see the heavily used subjects by how dirty the cards are, but getting exact statistics on search terms is more useful anyway. i would also like to thank marc truitt for his time and contributions to ital. marc recently finished serving for four years as ital editor. he helped me remember library technology. i wanted to know about his collaboration with judith carter. he said that he “thought no one this side of pluto could do as well as she” as managing editor. we are lucky to have had brave librarians like ranganathan, carter, and truitt. although i enjoy remembering the past, i am very happy to utilize modern technology in my library. i don’t want to live in the past, but i definitely don’t want to forget it either. thank you library technology pioneers. references 1. nicholson baker, “discards,” the new yorker, april 4, 1994, vol. 70, no. 7, p. 64-85. student use of library computers: are desktop computers still relevant in today’s libraries? susan thompson information technology and libraries |december 2012 20 abstract academic libraries have traditionally provided computers for students to access their collections and, more recently, facilitate all aspects of studying. recent changes in technology, particularly the increased presence of mobile devices, calls into question how libraries can best provide technology support and how it might affect the use of other library services. a two-year study conducted at california state university san marcos library analyzed student use of computers in the library, both the library’s own desktop computers and laptops owned by students. the study found that, despite the increased ownership of mobile technology by students, they still clearly preferred to use desktop computers in the library. it also showed that students who used computers in the library were more likely to use other library services and physical collections. introduction for more than thirty years, it has been standard practice in libraries to provide some type of computer facility to assist students in their research. originally, the focus was on providing access to library resources, first the online catalog and then journal databases. for the past decade or so, this has expanded to general-use computers, often in an information-commons environment, capable of supporting all aspects of student research from original resource discovery to creation of the final paper or other research product. however, times are changing and the ready access to mobile technology has brought into question whether libraries need to or should continue to provide dedicated desktop computers. do students still use and value access to computers in the library? what impact does student computer use have on the library and its other services? have we reached the point where we should reevaluate how we use computers to support student research? california state university san marcos (csusm) is a public university with about nine thousand students, primarily undergraduates from the local area. csusm was established in 1991 and is one of the youngest campuses in the 23-campus california state university system. the library, originally located in space carved out of an administration building, moved into its own dedicated library building in 2004. one of the core principles in planning the new building was the vision of the library as a teaching and learning center. as a result, a great deal of thought went into the design of technology to support this vision. rather than viewing technology’s role as just supporting access to library resources, we expanded its role to providing cradle-to-grave support for the entire research process. we also felt that encouraging students to work in the library would encourage use of traditional library materials and the expertise of library staff, since these resources would be readily available.1 susan thompson (sthompsn@csusm.edu) is coordinator of library systems, california state university san marcos. student use of library computers | thompson 21 rethinking our assumptions about library technology’s role in the student research process led us to consider the entire building as a partner in the students’ learning process. rather than centralizing all computer support in one information commons, we wanted to provide technology wherever students want to use it. we used two strategies. first, we provided centralized technology using more than two hundred desktop computers, most located in four of our learning spaces: reference, classrooms, the media library, and the computer lab. three of these spaces are configured like information commons, providing full-service research computers grouped around the service desks near each library entrance. in addition, simplified “walk-up” computers are available on every floor. the simplified computers provide limited web services to encourage quick turnaround and no login requirement to ensure ready access to library collections for everyone, including community members. the other major component of our technology plan was the provision of wireless throughout the building, along with extensive power outlets to support mobile computing. more than forty quiet study rooms, along with table “islands” in the stacks, help support the use of laptops for group study. however, only two of these quiet studies, located in the media library, provide desktop computers designed specifically to support group work. in 2009 and again in 2010, we conducted computer use studies to evaluate the success of the library’s technology strategy and determine whether the library’s desktop computers were still meeting student needs as envisioned by the building plan. the goal of the study was to obtain a better understanding of how students use the library’s computers, including types of applications used, computer preferences, and computer-related study habits. the study addressed several specific research questions. first, librarians were concerned that the expanded capabilities of the desktop computers distracted students from an academic and library research focus. were students using the library’s computers appropriately? second, the original technology plan had provided extensive support for mobile technology, but the technology landscape has changed over time. how did the increase in student ownership of mobile devices—now at more than 80 percent—affect the use of the desktop computers? finally, did providing an application-rich computer environment encourage student to conduct more of their studying in the library, leading them more frequently to use traditional library collections and services? this article will focus on the study results pertaining to the second and third research questions. we found that, according to our expectations, students using library computer facilities also made extensive use of traditional library services. however, we were surprised to discover that the growing availability of mobile devices had relatively little impact on students’ continuing preference for libraryprovided desktop computers. literature review the concept of the information commons was just coming into vogue in the early 2000s, when we were designing our library building, and it strongly influenced our technology design as well as building design. information commons, defined by steiner as the “functional integration of technology and service delivery,” have become one of the primary methods by which libraries provide enhanced computing support for students studying in the library.2 one of the changes in libraries motivating the information-commons concept is the desire to support a broad range of learning styles, including the propensity to mix academic and social activities. particularly influential to our design was the concept of the information commons supporting students’ projects “from inception to completion” by providing appropriate technologies to facilitate research, collaboration, and consultation.3 information technology and libraries |december 2012 22 providing access to computers appears to contribute to the value of libraries as “place.” shill and toner, early in the era of information commons, noted “there are no systematic, empirical studies documenting the impact of enhanced library buildings on student usage of the physical library.” 4 since then, several evaluations of the information-commons approach seem to show a positive correlation between creation of a commons and higher library usage because students are now able to complete all aspects of their assignments in the library. for example, the university of tennessee and indiana university have shown significant increases in gate counts after they implemented their commons.5 while many studies discuss the value of information commons, very few look at why library computers are preferred over computers in other areas on campus. burke looked at factors influencing students’ choice of computing facilities at an australian university.6 given a choice of central computer labs, residence hall computers, and the library’s information commons, most students preferred the computers in the library over the other computer locations, with more than half using the library computers more than once a week. they rated the library most highly on its convenience and closeness to resources. perhaps the most important trend likely to affect libraries’ support for student technology needs is the increased use of mobile technology. the 2010 nationwide educause center for applied research (ecar) study, from the same year as the second csusm study, showed that 89 percent of students had laptops.7 other nationwide studies have corroborated this high level of laptop ownership.8 so, does this increased use of laptops and mobile devices have affect the use of desktop computers? the 2010 ecar study reported that desktop ownership (about 50 percent in 2010) had declined by more than 25 percent between 2006 and 2009, a significant period in the lifetime of csusm’s new library building. pew’s internet & american life project trend data showed desktop ownership as the only gadget category in which ownership is decreasing, from 68 percent in 2006 to 55 percent at the end of 2011.9 some libraries and campuses are beginning to respond to the increase in laptop ownership by changing their support for desktop computers. university of colorado boulder, in an effort to decrease costs and increase availability of flexible campus spaces, is making a major move away from providing desktop computers.10 while they found that 97 percent of their students own laptops and other mobile devices, they were concerned that many students still preferred to use desktop computers when on campus. to entice students to bring their laptops to campus, the university is enhancing their support for mobile devices by converting their central computer labs into flexible-use space with plentiful power outlets, flexible furniture, printing solutions, and access to the usual campus software. nevertheless, it may be premature for all libraries and universities to eliminate their desktop computer support. tom, voss, and scheetz found students want flexibility with a spectrum of technological options.11 certainly, they want wi-fi and power outlets to support their mobile technology. however, students also want conventional campus workstations providing a variety of functions, such as quick print and email computers, long-term workstations with privacy, and workstations at larger tables with multiple monitors that support group work. while the ubiquity of laptops is an important factor today, other forms of mobile devices may become more important in the future. a 2009 wall street journal article reported the trend for business travelers is to rely on smartphones rather than laptops.12 for the last three years, educause’s horizon reports have made support for non-laptop mobile technologies one of the top trends. the 2009 horizon report mentioned that in countries like japan, “young people equipped student use of library computers | thompson 23 with mobiles often see no reason to own personal computers.”13 in 2010, horizon reported an interesting pilot project at a community college in which one group of students was issued mobile devices and another group was not.14 members of the group with the mobile devices were found to work on the course more during their spare time. the 2011 horizon report discusses mobiles as capable devices in their own right that are increasingly users’ first choice for internet access.15 therefore, rather than trying to determine which technology is most important, libraries may need to support multiple devices. trends described in the ecar and horizon studies make it clear that students own multiple devices. so how do they use them in the study environment? head’s interviews with undergraduate students at ten us campuses found that “students use a less is more approach to manage and control all of the it devices and information systems available to them.”16 for example, in the days before final exams, students were selective in their use of technology to focus on coursework yet remain connected with the people in their lives. the question then may not be which technology libraries should support but rather how to support the right technology at the right time. method the csusm study used a mixed-method approach, combining surveys with real-time observation to improve the effectiveness of assessment and generate a more holistic understanding of how library users made their technology choices. the study protocol received exempt status by the university human subjects review board. it was carried out twice over a two-year period to determine whether time of the semester affected usage. in 2009, the study was administered at the end of the spring term, april 15 to may 3. we expected that students near the end of the term would be preparing for finals and completing assignments, including major projects. the 2010 study was conducted near the beginning of the term, february 4 to february 18. we that early term students would be less engaged in academic assignments, particularly major research projects. we carried out each study over a two-week period. an attempt was made to check consistency by duplicating each time and location. each location was surveyed monday—thursday, once in the morning and once in the afternoon during the heavy-use times of 11 a.m. and 2 p.m. the survey locations included two large computer labs (more than eighty computers each), one located near the library reference desk and one near the academic technology helpdesk. other locations included twenty computers in the media library, a handful of desktop computers in the curriculum area, and laptop users, mostly located on the fourth and fifth floor of the library. the fourth and fifth floor observations also included the library’s forty quiet study rooms. for the 2010 study, the other large computer lab on campus (108 computers), located outside the library, also was included for comparison purposes. we used two techniques: a quantitative survey of library computer users and a qualitative observation of software applications usage and selected study habits. the survey tried to determine the purpose for which the student was using the computer for that day, what their computer preference was, and what other business they might have in the library. it also asked students for their suggestions for changes in the library. the survey was usually completed within the five-minute period that we had estimated and contained no identifying personal information. the survey administrator handed-out the one-page paper survey, along with a pencil if desired, to each student using a library workstation or using a laptop during each designated observation information technology and libraries |december 2012 24 period. users who refused to take the survey were counted in the total number of students asked to do the survey. however, users who indicated they refused because they had already completed a survey on a previous observation date were marked as “dup” in the 2010 survey and were not counted again. the “dup” statistic proved useful as an independent confirmation of the popularity of the library computers. the second method involved conducting “over-the-shoulder” observations of students using the library computers. while students were filling out the paper survey, the survey administrator walked behind the users and inconspicuously looked at their computer screens. all users in the area were observed whether or not they had agreed to take the survey. the one exception was users in group-study rooms. the observer did not enter the room and could only note behaviors visible from the door window, such as laptop usage or group studying. based on brief (one minute or less) observations, administrators noted on a form the type of software application the student was using at that point in time. the observer also noted other, nondesktop computer technical devices in use (specifically laptops, headphones, and mobile devices such as smart phones), and study behaviors, such as groupwork (defined as two or more people working together). the student was not identified on the form. we felt that these observations could validate information provided by the users on the survey. results we completed 1,452 observations in 2009 and 2,501 observations in 2010. the gate counts for the primary month each study took place—70,607 for april 2009 and 59,668 for february 2010— show the library was used more heavily during the final exam period. the larger number of results the second year was due to more careful observation of laptop and study-group computer users on the fourth and fifth floor and the addition of observations in a nonlibrary computer lab rather than an increase of students available to be observed. the observations looked at application usage, study habits, and devices present, but this article will only discuss the observations pertaining to devices. in 2009, 17 percent of students were observed using laptops (see table1). this number almost doubled in 2010 to 33 percent. most laptop users were observed on the fourth and fifth floors where furniture, convenient electrical outlets, and quiet study rooms provided the best support for this technology. very few desktop computers were available, so students desiring to study on these floors have to bring their own laptops. almost 20 percent of students in 2010 were observed with other mobile technology, such as cell phones or ipods, and 16 percent were wearing headphones, which indicated there was other, often not visible, mobile technology in use. student use of library computers | thompson 25 table 1. mobile technology observed in 2009, 1,141 students completed the computer-use survey. however, we were unable to accurately determine the return rate that year. the nature of the study, which surveyed the same locations multiple times, revealed that many of the students were approached more than once to complete the survey. thus the majority of the refusals to take the survey were because the subject had already completed one previously. the 2010 study accounted for this phenomenon by counting refusals and duplications separately. in 2010, 1,123 students completed the survey out of 1,423 unique asks, resulting in a 79 percent return rate. the 619 duplicates counted represented about half of the 2010 surveys completed and could be considered another indicator of frequent use of the library’s computers. the 2010 results included an additional 290 surveys completed by students using the other large computer lab on campus outside the library. table 2. frequency of computer use 33% 16% 18% 17% 0% 5% 10% 15% 20% 25% 30% 35% laptop in use headphones in use mobile device in use

also indicated they were frequent users (see table 2). in 2009, 82 percent of students used the library computers frequently—49 percent daily and 33 percent several times a week. the frequency of use in the 2010 early term study dropped about 10 percent to 72 percent but with the same proportion of daily vs. weekly users. convenience and quiet were the top reasons given by more than half of students as to why they preferred the library computers followed closely by atmosphere. about a quarter of students preferred library computers because of their close access to other library services. table 3. preferred computer to use in the library the types of computer that students preferred to use in the library were desktop computers followed by laptops owned by the students (see table 3). it is notable that the preference for desktop computers changed significantly from 2009 and 2010: 84 percent of students preferred desktop computers in 2009 vs. 72 percent in 2010—a 12 percent decrease. not surprisingly, few students preferred the simplified walk-up computers used for quick lookups. however, we did not expect such little interest in checking out laptops, with only 2 percent preferring that option. the 2010 study added a new question to the survey to better understand the types of technology devices owned by students (see table 4). in 2010, 84 percent of students owned a laptop (combining the netbook and laptop statistics). almost 40 percent of students owned a desktop, therefore many students owned more than one type of computer. of the 85 percent of students that indicated they had a cell phone, about one-third indicated they owned smart phones. the majority of students own music players. the one technology students were not interested in was e-book readers, with less than 2 percent indicating ownership. 84% 6% 23% 2% 71% 5% 28% 2% 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% sit-down pc walk-up pc own laptop laptop checked out in library 2009 2010 student use of library computers | thompson 27 table 4. technology devices owned by students (2010) to understand how the use of technology might affect use of the library in general, the survey asked students what other library services they used on the same day they were using library computers. table 5 shows survey responses are very similar between the late term 2009 study and the early term in 2010. by far the most popular use of the library, by more than three-quarters of the students, was for study. around 25 percent of the students planned to meet with others, and 20 percent planned to use the media services. around 15 percent of students planned to checkout print books, 15 percent planned to use journals, and 10 percent planned to ask for help. the biggest difference for students early in the term was an increased interest (5 percent more) in using the library for study. the late-term students were 9 percent more likely to meet with others. by contrast, users in the nonlibrary computer lab were much less likely to make use of other library services. only 24 percent of nonlibrary users planned to study in the library, and 8 percent planned to meet with others in the library that day. use of all other library services was less than 5 percent by the nonlibrary computer users. 1% 1% 7% 31% 40% 52% 59% 77% 0% 20% 40% 60% 80% 100% kindle/book reader other handheld devices netbook smart

changes they would like in the library, and 58 percent of respondents provided suggestions. the question was not limited to technology, but by far the biggest request for change was to provide more computers (requested by 30 percent of all respondents). analysis of the other survey questions regarding computer ownership, and preferences revealed who was requesting more traditional desktops in the library. surprisingly, most were laptop users; 90 percent of laptop owners wanted more computers and 88 percent of the respondents making this request were located on the fourth and fifth floor, which were almost exclusively laptop users. the next most comments received were remarks indicating student satisfaction with the current library services: 19 percent of students said they were satisfied with current library services and 9 percent praised the library and its services. commonality of requests dropped quickly at that point, with the fourth most common request being for more

29 discussion the results show that students consistently prefer to use computers in the library, with 78 percent declaring a preference for the library over other computer locations on campus both years of the study. this preference is confirmed by the statistics reported by csusm’s campus it department, which tracks computer login data. this data consistently shows the library computer labs are used more than nonlibrary computer labs, with the computers near the library reference desk as the most popular followed closely by the library’s second large computer lab, which is located next to the technology help desk. for instance, during the 2010 study period, the reference desk lab (80 computers) had 6,247 logins compared to 3,218 logins in the largest nonlibrary lab (108 computers)—double the amount of usage. the data also shows that use of the computers near the reference desk increased by 15 percent between 2007 and 2010. supporting the popularity of using computers in the library is the fact that most students are repeat customers. table 2 shows 82 percent of the 2009 late-term respondents used the library computers several times a week with almost half using our computers daily. in contrast, 72 percent of the 2010 early term students used the library computers daily or several times a week. the 10 percent drop in frequency of visits to the library for computing applied to both laptop and desktop users and seems to be largely due to not yet receiving enough work from classes to justify more frequent use. the kind of computer that users prefered changed somewhat over the course of the study. the preference for desktop computers dropped from 84 percent of students in 2009 to 72 percent in 2010 (see table 3). one reason for this 12 percent drop may be related to how the survey was adminstered. the 2010 study did a more thorough job of surveying the fourth and fifth library floors where most laptop users are. as a result, the laptop floors represented 29 percent of the response in 2010 vs. only 13 percent in 2009. these numbers are also reflected in the proporation of laptops observed each year—33 percent in 2010 vs. 17 percent in 2009 (see table 1). the drop in desktop computer preference is interesting because it was not matched by an equally large increase in laptop preference, which only increased by 5 percent. the other reason for the decrease in desktop preference is likely due to the larger change seen nationwide in student laptop ownership. for instance, the pew study of gadget ownership showed a 13 percent drop in desktop ownership over a five-year period, 2006–2011, while at the same time laptop ownership almost doubled from 30 percent to 56 percent.17 however, it is interesting to note that, according to the pew study, in 2011 the percent of adults who owned each type of device was nearly equal— 55 percent for desktops and 56 percent for laptops. the 2010 survey tried to better understand students’ preferences by identifying all the kinds of technology they had available to them. we found that 77 percent of csusm students owned laptops and an additional 7 percent owned the netbook form of laptops (see table 4). the combined 84 percent laptop ownership is comparable with the 2010 ecar study’s finding of 89 percent student laptop ownership nationwide.18 this high level of laptop ownership may explain why the users who preferred laptop computers almost all preferred to use their own rather than laptops checked out in the library. despite the high laptop ownership and decrease in desktop preference, it is significant that the majority of csusm students still prefer to use desktop computers in the library. aside from the 72 percent of respondents who specifically stated a preference for desktop computers, the top suggestion for library improvement was to add more desktop computers, requested by 38 percent information technology and libraries |december 2012 30 of respondents. further analysis of the survey data revealed that it was the laptop owners and the fourth and fifth floor laptop users who were the primary requestors of more desktop computers. to try to better understand this seemingly contradictory behavior, we have done some further investigation. anecdotal conversations with users during the survey indicated that convenience and reliability are two factors affecting student’s decision to use desktop computers. the desktop computers’ speed and reliable internet connections were regarded as particularly important when uploading a final project to a professor, with some students stating they came to the library specifically to upload an assignment. in may 2012, the csusm library held a focus group that provided additional insight to the question of desktops vs. laptops. all of the eight-student focus group participants owned laptops, yet all eight participants indicated that they preferred to use desktop computers in the library. when asked why, participants indicated the reliability and speed of the desktop computers and the convenience of not having to remember to bring their laptop to school and “lug” it around. another factor influencing the convenience factor may be that our campus does not require that students own a laptop and bring it to class, so they may have less motivation to travel with their laptop. supporting the idea that students perceive different benefits for each type of computer, six of the eight participants owned a desktop computer in addition to a laptop. the 2010 study also showed that students see value in owning both a desktop and a laptop computer, since the 40 percent ownership of desktop computers overlaps the 84 percent ownership of laptops (see table 4). table 6. reasons students prefer using library computer areas for almost half of the students surveyed, one of the reasons for their preference for using computers in the library was either the ready access to library services or staff (see table 6). even more significant, when specifically asked what else they planned to do in the library that day besides using the computer (see table 5), more than 80 percent of the students indicated that they intended to use the library for purposes other than computing. the top two uses for the library were studying (76 percent in 2009, 81 percent in 2010) and meeting with others (35/26 percent), indicating the importance of the library as place. the most popular library service was the media 0% 5% 10% 15% 20% 25% 30% library services are close library staff are close 2009 2010 student use of library computers | thompson 31 library (20/22 percent) followed by collections with 16/13 percent planning to checkout a book and 15/13 percent planning to look for journals and newspapers. it is interesting that the level of use of these library services was similar whether early or late in the term. the biggest difference was that early term students were less likely to be working with a group but were slightly more likely to be engaged in general studying. even the less-used services, such as asking a question (10 percent) or using a reserve book (8 percent), exhibited an appropriate amount of usage if one looks at the actual numbers. for example, 8 percent of 1,123 2010 survey respondents represent 90 students who used reserve materials sometime during the 8 hours of the two-week survey period. to put the use of the library by computer users into perspective, we also asked students using the nonlibrary computer lab if they planned to use the library sometime that same day. only 24 percent of the nonlibrary computer users planned to study in the library that day vs. 81 percent of the library computer users; only 4 percent planned to use media vs. 24 percent; and 2 percent planned to check out a book vs. 13 percent. the implication is clear that students using computers in the library are much more likely to use the library’s other services. we usually think of providing desktop computers as a service for students, and so it is. however, the study results show that providing computers also benefits the library itself. it reinforces its role as place by providing a complete study environment for students and encouraging all study behaviors including communication and working with others. the popularity of the library computers provide us with a “captive audience” of repeat customers. conclusion the csusm library technology that was planned in 2004 is still meeting students’ needs. although most of our students own laptops, most still prefer to use desktop computers in the library. in fact, providing a full-service computer environment to support the entire research process benefits the entire library. students who use computers in the library appear to conduct more of their studying in the library and thus make more use of traditional library collections and services. going forward, several questions arise for future studies. csusm is a commuter school. students often treat their work space in the library as their office for the day, which increases the importance of a reliable and comfortable computer arrangement. one question that could be asked is whether the results would be different for colleges where most students live on campus or nearby. if the university requires that all students own their own laptop and expects them to bring them to class, how does that affect the relevance of desktop computers in the library? the 2010 study was completed just a few weeks before the first ipad was introduced. since students have identified convenience and weight as reasons for not carrying their laptops, are tablets and ultra-light computers, like the macbook air, more likely to be carried on campus by students and used them more frequently for their research? how important is it to have a supportive mobile infrastructure with features such as high speed wifi, ability to use campus printers, and access to campus applications? are students using smart phones and other mobile devices for study purposes? in fact, are we focusing too much on laptops, and are other mobile devices starting to take over that role? this study’s results make it clear that we can’t just look at data such as ecar’s, which show high laptop ownership, and assume that means students don’t want or won’t use library computers. as information technology and libraries |december 2012 32 the types of mobile devices continue to grow and evolve, libraries should continue to develop ways to facilitate their research role. however, the bottom line may not be that one technology will replace another but rather that students will have a mix of devices and will choose which device is best suited to a particular purpose. therefore libraries, rather than trying to pick which device to support, may need to develop a broad-based strategy to support them all. references 1. susan m. thompson and gabriella sonntag. “chapter 4:

 given  us.”  this  is  one  of  my  favorite  quotes  in  the  lord  of  the  rings  series  because  it   inspires  us  to  rise  to  the  occasion  and  perform  to  the  best  of  our  abilities.  it  also  implies  that  that   we  have  a  purpose  to  fulfill  within  a  predetermined  time  period.   although  my  term  in  office  is  three  years,  i’m  only  lita  president  for  one  year.  to  set  a  vision  and   goals,  establish  a  sense  of  urgency,  generate  buy-­‐in,  engage  and  empower  the  membership,   implement  sustainable  changes,  and  remain  positive  and  focused  –  all  within  one  year  while   holding  a  full-­‐time  job  –  is  challenging  to  say  the  least.     i’ve  been  very  fortunate  during  my  almost  eight-­‐year  tenure  at  the  university  of  houston  libraries   to  participate  in  numerous  professional  development  opportunities,  lead  change,  and  make  a   difference.  personal  and  professional  growth  has  always  been  very  important  to  me,  and  being  in   an  environment  that  encourages  me  to  become  a  better  librarian,  technologist,  manager,  and   leader  is  not  only  helpful  for  my  career,  but  also  extremely  rewarding  on  an  intellectual  level.  lita   has  benefited  that  training.   in  today’s  library  technology  landscape,  one  of  the  many  skills  leaders  need  to  possess  is  the   ability  to  effect  change.  as  lita  president,  i  have  put  many  changes  in  motion  and  am  happy  with   what  i  have  accomplished,  and  proud  of  our  board  and  the  members  who  volunteer  to  lead  and   effect  change.   as  i  reflect  over  the  past  year,  it’s  fair  to  say  that  lita,  despite  some  financial  challenges,  has  had   numerous  successes  and  remains  a  thriving  organization.  three  areas  –  membership,  education,   and  publications  –  bring  in  the  most  revenue  for  lita.  of  those,  membership  is  the  largest  money   generator.  however,  membership  has  been  on  a  decline,  a  trend  that’s  been  seen  across  ala  for   the  past  decade.  in  response,  the  board,  committees,  interest  groups,  and  many  and  individuals   have  been  focused  on  improving  the  member  experience  to  retain  current  members  and  attract   potential  ones.  with  all  the  changes

 membership.  at  ala  annual  2014,  the  financial   advisory  committee  was  established  to  respond  to  recommendations  from  the  financial   strategies  task  force,  adjusting  the  budget  to  make  a  number  of  improvements  while  planning  for   larger,  more  substantial  changes.   in  fall  2014  we  took  steps  to  improve  our  communications  by  establishing  the  communications  &   marketing  committee  and  appointing  a  social  media  manager  and  a  blog  manager.  the  blog  and   social  media  have  seen  a  steady  upward  trajectory  of  engagement  with  over  27,000  blog  views   since  september  2014  and  over  13,300  followers  on  twitter.  these  efforts  help  recruit  and  retain   members,  advertise  our  online  education  and  programming,  and  increase  attendance  at   conferences.       over  the  past  year,  nine  workshops  and  two  web  courses  were  offered,  many  of  which  sold  out   thanks  to  new  marketing  approaches.  the  forum  remains  popular  and  has  stellar  programming   and  keynote  speakers.  programs  and  workshops  at  ala  conferences  are  stronger  than  ever  and   continue  to  be  well  attended.  publications  also  remain  strong.  although  only  three  lita  guides   were  published  this  year,  partially  due  to  a  change  in  publishers,  there  are  many  more  in  the   pipeline.       finally,  the  search  for  a  new  executive  director  is  underway,  and  with  a  new  leader  comes  fresh   ideas  and  perspectives.  i  am  excited  about  lita’s  future.  the  incoming  board,  along  with  a  new   executive  director,  has  an  opportunity  to  make  national  and  lasting  impact  as  well  as  collaborate   with  outstanding  librarians  and  staff  in  this  division  and  across  ala.  lita’s  challenges  and   successes  are  shared  amongst  a  dedicated  team  of  volunteers,  and  together  we’ve  made  significant   changes.  i  believe  that  lita  members  will  continue  to  rise  to  the  occasion  and  make  incredible   things  happen  with  “the  time  that  is  given  us.”  lita  is  an  amazing  organization  because  of  its   members  and  their  passion  and  dedication.  i  couldn’t  be  prouder.  it  has  been  an  honor  and  a   privilege  to  serve  as  your  president.           j costs of library catalog cards produced by computer 121 frederick g. kilgour: ohio college library center, columbus, ohio production costs of 79,831 cards are analyzed. cards were produced by four variants of the columbia-harvard-yale procedure employing an ibm 870 document writer and an ibm 1401 computer. costs per card ranged from 8.8 to 9.8 cents for completed cards. . early in september, 1964, the yale medical library.put into routine operation the columbia-harvard-yale computerized technique for catalog card manufacture ( 1), and during the following three · years yale produced over 87,000 cards. the principal objective of the chy project was an on-line, computerized, bibliographic information retrieval system. however, the route selected for attaining the objective included manufacture of cards from machine readable data to keep up the manual catalog while machine readable records were being inexpensively accumulated for computerized subject retrieval. catalog cards were only one product of the system, but their production was designed to be as efficient as possible within constraints of the system. nevertheless, this paper will examine chy card production costs as though this segment of the system were an isolated procedure, yielding but one product, as is the case in classical library procedures. costing will disregard other benefits, such as accession lists and machine readable data produced for little, or no, additional expense. the columbia medical library and harvard medical library also installed ibm 870 document writers and tested the programs for card production, but neither library routinely produced cards. however, co122 journal of library automation vol. 1/ 2 june, 1968 lumbia produced its acquisitions lists until october, 1966, using chy techniques. harvard issued a similar list, but for a shorter period of time, and it was harvard's withdrawal early in 1966 that brought about the collapse of the project. nevertheless, other institutions adopted the chy procedure for catalog card production, among them the medical library at the university of rochester, which used the programs for two years following february, 1966. e. r. squibb & sons at east brunswick, new jersey, also uses the programs. at the university of kentucky an 870 document writer types catalog cards, but new programs were written to run on an ibm 7040 computer that recently have been recoded in cobol for an ibm 360/50. similarly, the library at philip morris, inc., richmond, virginia, rewrote the programs to run on an ibm 1620 computer which punches cards that drive an 870. the korean social science bibliography project of the human relations area files has elaborated the chy technique into its automated bibliographic system ( 2), which in turn is the base for another bibliographic system for mrican studies. the machine readable cataloging record of the chy mechanized system eventually became the great-grandfather of the marc ii format and contributed about as much to marc ii as would have been the case had their relationship been truly biological. although the columbia-harvard-yale project never did develop and activate its proposed bibliographic information retrieval system, r. k. summit working entirely independently has brought into successful operation his excellent dialog system ( 3) which is essentially the system that chy had in design stage. moreover, summit's system is definitely superior because it has several useful functions not contemplated in chy. nearly all reports on catalog card production limit study of costs to reproduction of cards and neglect other costs involved in preparing cards for the catalog. an exception is p. j. fasana's 1963 investigation wherein he found that library of congress cards, in seven copies and ready to be filed into a catalog, cost 16.6 cents per card; cards produced by a machine method consisting of a tape typewriter and a very small special purpose computer cost 9.9 cents ( 4). fasana used an hourly salary rate of $2.00. a study of early experience with chy production yielded 12.5 cents per card ( 1) whereas the present study shows that costs range between 8.8 and 9.8 cents per card, cards being ·in completed form, arranged in packs for individual catalogs, and ready for bursting before alphabetizing for filing. methods · during the course of the three years in which the chy programs were in operation, four variant techniques were used for card production. the first three with their limitations have been described · elsewhere ( 5). briefly, the initial system consisted of keypunching from worksheets, _listing the punch cards on an ibm 870 document writer, proofreading and costs of library catalog cards/ kilgour 123 correcting, processing the proofread and corrected punch cards on an ibm 1401 computer which produced punch card output that, in tum, was used to drive the 870 document writer for production of catalog cards on oneup forms. in the next arrangement, printing of cards on one-up forms was accomplished on an ibm 1401 computer driving an upperand lowercase print chain. in the third procedure, a two-up card form replaced the one-up form. finally, the medical library returned the 870 document writer to the manufacturer, and the 1401 was programmed to do the prooflisting in upper and lower case. the yale bibliographic system (6) replaced the chy routines on 25 july 1967. the keypuncher kept time records for the various activities listed in table 1 throughout the period of this study. during the first two months of operation, design for recording data was inadequate. subsequently an individual would, albeit infrequently, fail to record time elapsed, so that production of 7,630 cards was omitted from the study, leaving a total of 79,831 to be included. on several occasions during the fourth part of the study, the second proofreading was suspended, and only correction carried out. hence, time expended in this category is less than in the previous three periods. at first an ibm 1401 computer in the yale computer center was used, the center being located about a mile from the medical library. subsequently, another 1401 modified to drive an upperand lower-case print chain and located in the medical sc;hool was employed. later this machine was transferred to the administrative data systems computer center, which moved to a new location not long after it assumed operation of the 1401. still later, the 1401 was again transferred, this time to the yale computer center. as can be seen from the computer charges in table 1, these wanderings about new haven appear to have had no effect on operating efficiency. time recorded for each computer run was actual time clocked by the operator. other times were recorded by the individual performing the operation. ·. salaries used in the cost calculation were salaries being paid in june, 1967, which were, of course, appreciably higher than those in the autumn of 1964; hourly rate for the first proofreader in table 1 was $2.62 ~nd for the second $2.21. hourly rental for the 870 document writer was $.78. rate of computer charges employed in the calculation was $20 per hour, a rate that had existed during the last year or so during which data was collected. initially, computer charges had been $75 an hour, but they dropped precipitously during the first two years. costs for catalog card stock were the lowest cost charged for the two types of forms. since these forms were not standard items during the years of the study, their prices

' i li ii ii '· ,, .. '· ,, ' • ,, 126 journal of library automation vol. 1/ 2 june, 1968 even though other benefits are not reflected in comparative costs, it is clear from fasana's findings that the chy computer-produced cards cost far less than do lc cards, and have a similar cost to those produced mechanically on which fasana reported. although there appears to be no published evidence that photocopying techniques can produce finished catalog cards at less expense than 9 cents, it is possible that some photoreproduced cards may be less expensive than those described in this article. however, it must be pointed out that photo-reproduced cards are products . of single-product procedures, whereas the chy cards are one of several system products. increase in cost between procedure three and procedure four was due to increase in cost of prooflisting in upper and lower case on the 1401 computer as compared to prooflisting on the 870 document writer. this cost increase was not detected until calculations were done for this investigation, and therein lies a moral. it was the policy at the yale library for all programming to be done by library programmers, since various inefficiences, and indeed catastrophes, had occasionally been observed when non-library personnel had prepared programs for library operations. the single exception to this policy was the proof program, which this investigation reveals used an exhorbitant amount of time-one-third of that required for subsequent card production. since it had been felt that writing and coding a prooflisting program. was perfectly straightfmward, an outside programmer of recognized ability was employed to write and code the program. because the program was simple, and because the programmer had high competence, efficiency of the program was never checked as it should have been. this episode raises the question that if even the wary can be trapped, how can the tmwary avoid pitfalls? there is no satisfactory answer, but it would appear that some difficulties could be avoided by review of new programs by experienced library programmers, of which there are unfortunately far too few. comparison with data such as that in table 1 will also be helpful, but not definitive, in evaluating new programs. of course, when widely used library computer programs of recognized efficiency are generally available, magnitude of the pitfalls will have been greatly reduced. concl"qsion computer-produced catalog cards, even when they are but one of several system products, can be prepared in finished form for a local catalog less expensively and with less delay than can library of congress printed cards. computer card production at 8.8 to 9.8 cents per completed card appears to be competitive with other procedures for preparing catalog cards. however, undetected inefficiency in a minor program increased costs, thereby emphasizing need to insure efficiency in programs used routinely. costs of library catalog cards/

| kim 99 yong-mi kim factors affecting university library website design factors include usability testing and institutional forces.5 because website design studies are sparse, this study examines the success of technology utilization studies to further identify factors that are pertinent to website design in order to provide a comprehensive view of web design success factors. a review of literature related to university library website design will be offered in the next section. the research methods, which discuss the data collection strategies and the measurements used in the current study, will be followed by the literature review. the findings of the study will later be reported and discussed after the research methods section. the paper will then conclude with an overview of the implications the findings have for academia and managers. ■■ literature review this section offers an overview of the existing website design literature and relevant success factors. these factors include institutional forces, supervisors’ technical knowledge and support, input from secondary sources, and input from users. because the aforementioned elements are identified as independent variables, this study also adopts them as such. following existing studies, website success factors are identified from the utilitarian perspective.6 the dependent variables are (1) the extent to which website designers meet users’ needs, (2) the extent to which users perceive ulwr to be useful, and (3) their actual usage. in this manner, the evaluation of success is measured from different perspectives. this discussion of the independent and the dependent variables appears in the conceptual model, figure 1. institutional forces institutional forces refer to as organizations following other organizations practices to secure efficiency and legitimacy. existing studies have identified three institutional forces: coercive, mimetic, and normative.7 coercive force takes place when an organization pressures others to adopt a certain practice. it is higher when an organization is a subset of another organization. in this research context, the university could be an agent of coercive force. mimetic force refers to organizations following other organizations’ practices, and it is especially common for organizations within the same industry group.8 because organizations within existing studies have extensively explored factors that affect users’ intentions to use university library website resources (ulwr); yet little attention has been given to factors affecting university library website design. this paper investigates factors that affect university library website design and assesses the success of the university library website from both designers’ and users’ perspectives. the findings show that when planning a website, university web designers consider university guidelines, review other websites, and consult with experts and other divisions within the library; however, resources and training for the design process are lacking. while website designers assess their websites as highly successful, user evaluations are somewhat lower. accordingly, use is low, and users rely heavily on commercial websites. suggestions for enhancing the usage of ulwr are provided. f rom a utilitarian perspective, a website evaluation is based on users’ assessments of the website’s instrumental benefits.1 if a website helps users complete their tasks, they are likely to use the website. following this line of reasoning, dominant research has reported that users are most likely to use university library website resources (ulwr) when they can help with user tasks.2 although we know now that the utilitarian perspective should be applied to web design, not clear is the extent to which web designers consider users’ needs and, likewise, the extent to which users consider ulwr to be successful in terms of meeting their needs. also not clear are what factors other than user needs influence university library website design. this is not a trivial issue because university libraries have invested a massive number of resources into providing web services and need to justify their investments to stakeholders (such as the university) by demonstrating their ability to meet users’ needs.3 also important is the identification of these factors because web design and website performance are closely correlated.4 as a consequence, investigating factors that influence successful university library website design and providing managerial guidance is a timely pursuit. later, the objectives of this paper are twofold: 1. what factors influence university library website design? 2. to what extent do website designers and users consider the university library website to be successful? to explore these research questions, this study identifies factors influencing university library website design that have been reported in existing literature. these yong-mi kim (yongmi@ou.edu) is assistant professor, school of library and information studies, university of oklahoma, tulsa, oklahoma. 100 information technology and libraries | september 2011 although it is a critical factor for website success, there is little evidence that website designers receive strong support from their supervisors. research shows that supervisors’ lack of knowledge about websites inhibits user-centered website design.17 a respondent from chen et al.’s study reports, “it’s really a pain trying to connect with our administration on the topic of web design and usability, because even definitions are completely out the window” and “the dean and the associate directors know little about the need for usability and view it as a last minute check-off, so they can say that the web site is tested and usable.”18 lack of supervisor support inhibits website usability.19 input from secondary sources website designers typically aggregate information from secondary sources rather than from users. identified secondary sources are consultations with experts, other divisions within the library, webmasters, web committees, and focus groups.20 the most widely used method is consultation with experts.21 experts uncover technical flaws and any obvious usability problems with a design,22 facilitate focus groups,23 and create new information architecture.24 because they are experts, however, their ways of thinking may not be the same as users.’25 research shows that 43 percent of the problems found by expert evaluators were actually false alarms and that 21 percent of users’ problems were missed by those evaluators. if this analysis is true, expert evaluators tend to miss and incorrectly identify more problems than they correctly identify;26 consequently, expert testing should not substitute for user testing.27 another problem with secondary sources is that web committees “are ignorant about integrating design with usability and focus on their own agenda.”28 nonetheless, because of the lack of available resources to conduct more rigorous usability tests and the difficulty of collecting information directly from users, secondary sources such as expert evaluations are commonly used.29 input from users user input provides a great advantage for directly finding out users’ needs and integrating a user-centered design during the development stage.30 often, information from secondary sources makes assumptions about users’ needs.31 to discover users’ genuine needs, designers can conduct a regular user survey and/or seek out users’ input.32 by surveying users’ needs, one can overcome criticism such as, “most websites are created with assumptions of more expert knowledge than the users may actually possess,” and can address users’ needs more effectively.33 discovering users’ needs goes beyond usability testing because information obtained directly the same industry face similar problems or issues, mimetic decisions can reduce uncertainty and secure legitimacy.9 in this context, website designers may analyze and emulate other universities’ websites to claim that their websites are congruent with successful websites, thereby justifying their managerial practices. normative force is associated with professionalism.10 normative force occurs when the norms (e.g., equity, democracy, etc.) of the professional community are integrated into organizational decision-making. in a library setting, website designers may follow a set of value systems or go to conferences to discover ways to better deliver services. there is evidence that website designers follow other organizations.11 this phenomenon is known as isomorphism. the appearance and the structure of websites show isomorphic patterns when an organization follows examples of other organizations’ websites or conforms to institutional pressures.12 another study reports coercive forces in the design of university library websites; the parent institution exercises power over library website design by providing guidelines, and later, the design is not independent.13 supervisors’ technical knowledge and support literature on supervisors’ knowledge of and support for technology has long been recognized as one of the most important technology success factors.14 if supervisors are knowledgeable about technology, they are likely to support and provide resources for training.15 supervisors’ technical knowledge also serves as a signal for the importance of the utilization of technology within the organization; consequently, employees actively look for ways to utilize technology and vigorously adopt technology.16 figure 1. conceptual model for website design success factors affecting university library website design | kim 101 march and may 2009. a total of 315 responses were collected (139 males and 176 female; 148 undergraduates, 101 master ’s, and 66 doctoral/faculty; business 152, human relations 51, psychology 43, engineering 41, education 20, other 8). because detailed discussion of the user side of this sample appears elsewhere,36 it will not be repeated here to avoid redundancy. because sparse research has been done in this area, the questionnaire and its measurements were created based on literature relating to the successful deployment of technology, but they were modified to fit into the website design context. because of this modification, the finalized instrument was pretested and pilot tested before use in this study.37 the institutional forces are measured in three categories: coercive isomorphism (i.e., following the university guidelines regarding website creation), mimetic isomorphism (i.e., investigating other university websites and investigating commercial websites), and normative isomorphism (i.e., attending conferences). following existing studies, supervisors’ knowledge and support are assessed by the web designer in two areas: the extent to which a supervisor is knowledgeable about technology and aware of the importance of technology. the supervisor ’s support for the website is measured by asking web designers about the extent to which their supervisors allocated resources and offered training. input from secondary sources is measured by asking the extent to which website designers consult sources such as experts, other divisions, webmasters, and web committees. input from users is measured by the extent to which web designers collect information from website users. finally website successes are measured by two categories: assessments made by the web designers and the website users themselves. the finalized measurements and the sources appear in table 1. ■■ report of findings this section reports the empirical findings of each category discussed in the previous section. figure 2 shows institutional forces that influence university library website design. the first category is coercive force, the second category is mimetic forces, and the third category is normative force. it is clear that the majority of university library web designers (75 percent) comply with the guidelines given by the university, which is a measurement of coercive force; and also designers investigate other universities’ websites (75 percent) and commercial websites (59 percent), which is a measurement of mimetic forces; however, designers don’t appear to actively attend conferences that influence website design, which is a measurement of normative force. from users will reveal what users want and what should be done to meet their needs, thereby enhancing ulwr usage. however, research shows that this aspect is not actively integrated into web design due to the lack of support from supervisors.34 website success success can be measured according to the website’s purpose: to what extent does the website meet users’ needs? in the university library website context, following a utilitarian perspective, researchers measured the success by the degree of ulwr integrated into users’ tasks and users’ frequent visits to the website.35 these two measurements, when combined with the designers’ perceptions of success, will allow one to measure the users’ and designers’ perspectives of website success. by measuring from these two sides, if there is a discrepancy between the two success outcomes, it will prompt designers to adjust their viewpoints to align their success measures with users. ■■ research methods this section discusses the sampling strategies and the measurements for the independent and the dependent variables. because one of the contributions of this study is to compare users’ and designers’ perceptions of website success, the samples are drawn from two groups: one is from university library website designers and the other one is from university library users. for the designer side, it is directly collected from university library website designers; later, libraries without website designers within the library are excluded. the designer sample is identified from the publicly available yahoo academic library list (http://dir.yahoo.com/ reference/libraries). the list contains 448 academic libraries, including those outside the united states. the research assistant made a phone call to the libraries that reside in the united states and verified the existence of website designers within the library, which included 86 academic libraries. if a library had a website designer, the research assistant contacted the person and invited him or her to participate in the study. because of difficulties contacting website designers, the research assistant was able to collect 16 responses between may 2009 and february 2010. once the graduate assistant identified the unreachable designers, the researcher e-mailed those designers between january and april of 2010 and added 30 more responses to the dataset, which resulted in a total of 46 responses (a 54 percent response rate). for the user side, a survey questionnaire was sent to faculty, doctoral, master ’s, and undergraduate students between 102 information technology and libraries | september 2011 the second group of factors that affects website design is supervisors’ knowledge about technology and support for the utilization of technology (see figure 3). web designers have a somewhat mixed perception about their supervisors’ technical knowledge. more specifically, 37 percent of respondents responded that their supervisors do not have good knowledge about technology; 23 percent responded that their supervisors were somewhat knowledgeable about technology; and 40 percent responded that their supervisors have good knowledge about technology; thus, web designers have mixed evaluations about supervisors’ technical knowledge. web designers reported that their supervisors’ perceptions of the importance of technology and websites are higher than their technical knowledge. approximately 60 percent of designers responded that their supervisors emphasize the importance of technology and websites, and the remaining respondents answered that their supervisors are somewhat aware of the importance or do not value it at all. table 1. instrument construct

of respondents reported that they consult with web experts; over 70 percent responded that they integrate input from other divisions; and around 70 percent consult with webmasters. the utilization of secondary information sources for website creation is very high except for focus groups. the most widely used technique in this category is expert consultations followed by consultations with other divisions within the library. web designers also consider input from webmasters and web committees. figure 6 shows the extent to which website designers apply input directly derived from web users. around half of respondents reported that they obtain information from user surveys, and around 70 percent responded that they consider users’ input collected via comments, feedback, and complaints. figure 4 shows the extent to which supervisors support web designers. fifty-five percent of respondents reported that they have good web creation tools; 44 percent responded that they have enough budget for website creation, and almost a similar rate of respondents (39 percent) reported that they do not have adequate budgets for website creation. the last two questions concerning training show somewhat different results from the findings of the first two questions. the majority of web designers do not get technology-related or website creation-related training. less than one-third of respondents reported that they receive enough technology-related and web creationrelated training. the findings of the use of secondary sources show in figure 5 that web designers actively leverage such information sources for web design. by category, over 80 figure 3. supervisor’s knowledge about technology figure 4. supervisor’s support figure 5. input from secondary sources figure 6. input

discussion will first cover the most influential factors first followed by the least influential elements in designing a university library website. first, the most influential factors for website designers are expert opinions and consultations with other divisions within the library. these may be the most important factors because relying on experts allows designers to discover users’ needs while saving costs. web designers also consider input from webmasters and web committees. coercive and mimetic forces are also highly significant factors affecting web designers. the university library is a subset of the university, and thus, designers may need to align themselves with university policy. also, designers can claim legitimacy by imitating other successful university websites, thereby securing necessary resources and support for website creation; however, web designers are much less likely to imitate commercial websites. this finding is consistent with existing reports that organizations imitate other successful organizations’ managerial practices that are within the same industry category.38 the least influential website creation factors are supervisors’ knowledge, which in turn impacts low budget allocations, and web designers’ technical training. this finding is consistent with successful technology deployment literature that shows supervisors’ technical knowledge is highly correlated with budget allocations.39 the lack of training for web designers does not appear to be improved since the last study, which was conducted in 2001;40 library ■■ website success website success is evaluated from two sides: designer opinion and user opinion. overall, designers evaluated their websites to be highly successful. they believe that they meet users’ needs, provide better services via the web, satisfy users’ needs, and provide quality services. later, their evaluation of their website is extremely positive, as reported in figure 7. figure 8 shows users’ perceptions of the usefulness of ulwr. users generally agree that ulwr are useful for their academic projects. more specifically, 55 percent responded that they are able to finish their tasks quickly because of the resources; 65 percent reported that they could increase their productivity; and 67 percent responded that they enhanced project quality thanks to the resources. on the other hand, a significant portion of respondents (more than 30 percent) do not think or have no opinions that ulwr are useful for their academic tasks. figure 9 investigates how often users visit university library websites. approximately 30 percent reported that they never visited or rarely visited the university library website. thirty-two percent made a visit to the website a couple of times a month, and approximately 40 percent visited the library website a couple of times a week or daily. figure 10 examines the users’ utilization of ulwr versus commercial website resources. the responses from 315 users show that they utilize commercial websites more than ulwr. specifically, 46 percent of respondents reported that they use less than 20 percent of ulwr and only 8 percent utilize ulwr more than 80 percent. in contrast, 14 percent utilize less than 20 percent of commercial website resources, and 22 percent utilize more than 80 percent of commercial website resources. the figure 7. website success evaluated by design figure 8. users’ perceptions of website usefulness factors affecting university library website design | kim 105 from a utilitarian perspective, web designers primarily need to consider the ability of the website to meet users’ needs. usefulness again needs to be evaluated by users. according to user assessments ulwr are somewhat satisfactory but not strong enough to rely heavily on for academic projects. it is an alarming fact that users use commercial website resources at a much higher rate than ulwr. this is somewhat disturbing given that web designers strive to provide good services to users, and libraries have invested massive resources into providing online services. this study has implications for academia and practitioners. for academia, there has been sparse research on web design studies from a designer standpoint. it may be because of difficulties in collecting data directly from website designers. from this line of research, this study enhances the understanding of what factors influence university web design. although university websites may be deemed successful, information managers should discover why the majority of users turn to commercial websites for their academic projects. without addressing this problem, the existence of library websites may be compromised. although there is evidence that libraries consider user input, it may not accurately represent all user populations because only extremely satisfied or extremely dissatisfied users tend to provide feedback;43 consequently, a regular survey may facilitate the utilization of ulwr. finally, supervisors’ technical knowledge is found to be low. this problem may be alleviated as time goes on because new generations are more aware of the importance of technology. in the meantime, web designers are encouraged to actively communicate with supervisors about the value of the utilization of technology and seek more financial support. this study’s data have some limitations. although the web designers are usually self-taught rather than formally trained.41 one promising finding, though, is that despite the relatively low technical knowledge held by supervisors, the respondents tend to rank highly when it comes to their perceptions of the importance of technology. compared with other institutional forces, normative force is relatively low. this kind of institutional force is higher at the early stage of technology adoption. in other words, the majority of universities have already launched their websites and have established rules and policies, so libraries are already past this stage. also, input from user surveys is relatively low. this may be because it is very costly, and they have other sources to turn to such as other universities’ successful websites. website success evaluations by web designers and users show discrepancies. overall, web designers evaluate their websites to be highly successful, while user ratings offer a different picture. this incongruity is a red flag in terms of ulwr usage. the majority of users report that they turn to commercial websites more than ulwr, and one-third never or rarely visit the university website. the disparity of the success between web designers and users may be attributed to the sources of information that website designers rely on. more specifically, existing studies report that input from experts and website committees is incongruent with what users really want, while feedback from focus groups can assist in understanding users’ needs.42 ■■ conclusions this study

and libraries | december 2011 ■■ more from the far side of the k–t boundary in my september column, i offered some old-school suggestions for how we as a profession might cope with our confused and unbalanced times. since then, several more have crossed my mind, and i thought i’d offer them, for what they may be worth: ■■ we can outsource everything but responsibility. whether it’s “the cloud,” vendor acquisition profiles, or shelfready cataloguing, outsourcing has become a popular way of dealing with budgetary and staffing stresses during the past few years. generally speaking, i have serious reservations about outsourcing our services, but i do recognize the imperatives that have caused us to resort to them. that said, in farming out critical library services, we do not at the same time gain license to farm out responsibility for their efficient operation. oversight and quality control are still up to us, and it simply will not wash with patrons today, next year, or a century from now to be told that a collection or service is unacceptably substandard because we outsourced it. a vendor’s failure is our failure, too. it’s still “our stuff,” and so are the services. ■■ we’re here to make decisions, not avoid them. document delivery, patron-driven acquisitions, usability studies, and evidence-based methodologies should help to inform and serve as validity checks for our decisions, not be replacements for them. as with outsourcing and our over-reliance on technology-driven solutions, i fear that these services and methodologies are in real danger of becoming crutches, enabling us to avoid making decisions that may be difficult, unpopular, tedious, or simply too much work. but if decisions regarding collections and services can be reduced to simple questions of demand or the outcome of a survey, then who needs us? it’s our job to make these decisions; demandor survey-driven techniques are simply there to assist us in doing so. ■■ relevance is relative. we talk about “relevance” in much the same breathlessly reverential voice as we speak of the “user” . . . as if there were but one, uniquely “relevant” service model for that single, all-encompassing “user.” one of the perils of our infatuation with “relevance” is the illusion that by adopting this or that technology or targeted service, we are somehow remaining relevant to “the user.” which user? just as not all patrons come to us seeking potboiler romances, so too not all users demand that all services and collections be made available electronically, over mobile platforms. since we do recognize that our resources are finite, rather than pandering to some groups at the expense of others with trendy temporal come-ons, why not instead focus on long-term services and collections that reflect our values? the patrons who really should matter most to us will respect us for this demonstration of our integrity. ■■ libraries are ecosystems. as with the rest of the world around us, libraries comprise arrays of interlocking, interdependent, and often poorly understood/ documented entities, services, and systems. they’ve developed that way over centuries. and just as so often happens in the larger world, any and every change we make can cause a cascade of countless other changes, many of which we might not anticipate before making that seemingly simple initial change. we are stewards of the libraries in which we work: our obligation, as librarians, is to respect what was bequeathed to us, to care for and use it wisely, and to pass it on to those who follow in at least the condition in which we received it—preferably better. environments, including libraries, change and evolve of course, but critics of the supposedly slow pace of change in libraries fail to grasp that our role is just as much that of the conservationist as it is the advocate of development and change. our mission is not change for change’s sake; rather, it is incremental, considered change that will benefit not only today’s patrons and librarians, but respect those of the past and serve those of the future as well. perhaps librarians need an analogue to the medical profession’s hippocratic oath: primum non nocere, “first, do no harm.” ■■ innocents abroad probably few ital readers will be aware (i certainly wasn’t!) that mark twain’s bestselling book during his lifetime was not tom sawyer or huckleberry finn—or any of a host of others of his now better-remembered works— but rather his 1869 travelogue innocents abroad, or the new pilgrims’ progress. the book, which i’ve been savoring in my spare leisure reading time over the past several months, records in journal form twain’s involvement in a voyage in 1867 by a group of american tourists to various locales in mediterranean europe, northern africa, and the near east. in the book, twain gleefully skewers marc truitt marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. outgoing editor’s column: parting thoughts outgoing editor’s column | truitt 153 committee assignments go, i think it fair to say that this is probably one of the more thankless. board members must be expert in all areas of technology, and as important, willing and able to do a credible job of pretending to be so in those areas where they are not expert! they must be able to recognize and create good prose and to offer authors practical, constructive insights and guidance in the sometimes black art of turning promising manuscripts into great articles. as i think many ital authors will attest, they do a superb job at this. they also write some of the most interesting and perceptive editorial columns you’ll see in ital! ■■ judith carter. it’s really impossible to overstate the contributions made by judith to ital. other than a brief four-year interlude during which i served in the role, judith has been managing editor for much of the past decade and more. she taught me the job when she relinquished it in early 2004, and then graciously offered to take it back again when i was named editor four years later. more than any other single person, she is responsible for the ital you hold in your hands, and she does it with skill and tireless dedication. she also has been my coach, my confidante, and—as only a true friend can be—even my butt-kicker when i was late in observing a deadline, which has not infrequently been the case. thank you for everything, judith. ■■ dan and john. the late dan marmion brought me on board at ital as a board member in 2000; he later asked me to serve as his managing editor. he also encouraged me to succeed john webb as editor in 2007. from both dan and john i learned much about the role of an editor and especially about what ital could and should be. i am endlessly appreciative for their mentoring and hope that i have been reasonably successful in maintaining the high standards that they set for the journal. ■■ the authors. without interesting, well-researched, and timely content, there would be no ital. i have been blessed with a rich and nearly constant supply of superb manuscript submissions that the folks who make up the ital “publication machine” have then turned into a highly stimulating and readable journal. i hope you agree. ■■ the readers. and finally, i thank all of you, gentle readers. you are the reason that ital exists. i have been grateful for your support, your patience, and your always-constructive suggestions. beginning with the march 2012 issue, ital will be edited by bob gerrity of boston college. i’ve been acquainted with bob for a number of years, and i can’t think of a better person to guide this journal through the tour-goers, those they encounter, and of course himself; as with twain generally, it is at turns witty, outlandish, biting, and—by today’s lights—completely lacking in political correctness. in short, it’s vintage mark twain: delicious! i mention innocents abroad not simply because i’m currently enjoying it (and hoping that by saying so, i might pique some other ital reader ’s interest in giving it a test drive) but also because it—as with other books, songs, stories, etc., about journeys-taken—is a metaphor for life. we are all “innocents” in some sense as we traverse the days and years of growth in selfawareness, relationships, work, and all the other facets that make up life. it’s a comforting way of viewing the world, i think. i’ve served with ital in various capacities for more than eleven years. that’s a very long time in terms of one particular ala/lita committee. it’s now time for my journey and ital’s to part ways. this is my final column as editor of this journal. this “innocent” is debarking the ital ship and moving on. ital is the product of the dedicated labor of many people of whom i am but one. for some of them, it is a labor of love. as with the credits at the end of a film, it is customary for an editor in her or his final column to recognize and thank the people who made it all possible. i’d like to do so now. polite audience members know to remain until “the end” rolls by. i hope you’ll help me honor these people by doing so, too: ■■ mary taylor, valerie edmonds, and melissa prentice in the lita office. over the years, they’ve been unfailingly helpful to me, to say nothing of being nearly as unfailingly tolerant of my clueless and occasionally obstreperous, passive-aggressive ignorance of the byzantine ways of the ala bureaucracy. ■■ ala production services. production services folk are the professionals who, among innumerable other skills, copyedit and typeset manuscripts, perform miracles with figures and tables, and generally make ital into the quality product you receive (whether it is celluloseor electron-based). regardless of ital’s future publishing format and directions, count yourself fortunate as long as the good people in production services continue to play a role. i’d especially like to single out tim clifford, ital’s production editor, who over the past several years has brought skill, grace, stability, and a healthy dose of humor to this critical post. ■■ the members—past and present—of the ital editorial board. the editorial board is a lita committee; the members of this committee serve as the editor’s primary group of reviewer-referees of manuscripts submitted for publication consideration. as 154 information technology and libraries | december 2011 “happy trails,” and “t-t-t-t-that’s all, folks!” “the end.” changes that will be coming over the next few years. i wish him the very best and hope that he has as much fun in the job—and on the journey—as have i. from the managing editor i’d like to take this opportunity to give marc truitt my heartfelt thanks and best wishes as he leaves his longterm relationship with information technology and libraries (ital). i appreciate how he ably stepped into the role of managing editor (me) when i needed to resign to focus on my full-time job. a few years later he became the new editor and i accepted his request to be his me. i think we’ve had a good partnership. i’ve nudged marc about the production schedule while he has managed manuscripts, the peer review process, and eloquently represented the journal when needed. marc held and communicated a clear and scholarly view of the journal to the editorial board and to lita. i have fond memories of many cups of tea drunk in various ala conference venues while we discussed ital, lita, and shared news of mutual friends. we endured the loss of our friend and mentor dan marmion together a year ago september when marc wrote a letter which i read at the memorial service. this too may be my final issue of ital. it is unknown at time of printing. i support the online future of ital and have offered my services to robert gerrity until a paper version is no longer supported and we successfully transition my duties into an online environment/to a new me. i know he will take the journal into its new iteration with skill and grace. i have served lita and ital for over 13 years and am proud of the quality peer reviewed journal dan marmion, john webb, marc truitt, the editorial board members and i have shared with the members of lita. it has also been my honor to communicate with each of the authors and to facilitate their scholarly communication to our profession. without the authors, where would we be? thank you all, judith carter. editorial | truitt 3 w ithin the last few months, two provocative books have been published that take different approaches to the question of how we learn in the always-on, always-connected electronic environment of “screens.” while neither is specifically directed at librarians, i think both deserve to be read and discussed widely in our community. ■■ the shallows the first, the shallows: what the internet is doing to our brains (norton, 2010), by nicholas carr, is an expanded version of his article “is google making us stupid?” published in the july/august 2008 issue of atlantic monthly and discussed in this space soon after.1 carr’s arguments in the shallows will be familiar to those who read his earlier article, but they are more thoroughly developed in his book and worth summarizing here. carr’s thesis is that use of connective technology—the internet and the web—is leading to a remapping of cognitive reading and thinking skills, and a “shallowing” of these mental faculties: over the last few years i’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. . . . i’m not thinking the way i used to think. i feel it most strongly when i’m reading. i used to find it easy to immerse myself in a book or a lengthy article. . . . that’s rarely the case anymore. (5) the problem, as carr goes on to describe at some length, chronicling in detail the results of years of neurological investigations, is that the brain is “plastic.” “virtually all of our neural circuits—whether they’re involved in feeling, seeing, hearing, moving, thinking, learning, perceiving, or remembering—are subject to change.” and one of the things that is changing them the most drastically today is our growing reliance on digital information. the paradox is that as we repeat an activity—surfing the web and clicking on links, rather than engaging with linear texts, for example—chemically induced synapses cause us to want to continue the new activity, strengthening those links (34). this quality of plastic neural circuits that can be remapped, when combined with the “ecosystem of interruption technologies” of the internet and the web (e.g., in-text hyperlinks, e-mail and rss alerts, text messaging, twitter, multiple widgets, etc.) is resulting in what carr argues is a growing inability or unwillingness to engage with and reflect deeply upon extended text (91).2 as carr puts it, the linear, literary mind . . . [that has] been the imaginative mind of the renaissance, the rational mind of the enlightenment, the inventive mind of the industrial revolution, even the subversive mind of modernism . . . may soon be yesterday’s mind. (10) there is much more. carr offers pointed critiques of major internet players and the roles they play in facilitating and exploiting the remapping of our neural circuits. google, whose “profits are tied directly to the velocity of people’s information intake,” is to carr “in the business of distraction” (156–57). the google book initiative “shouldn’t be confused with the libraries we’ve known until now. it’s not a library of books. it’s a library of snippets. . . . the strip-mining of ‘relevant content’ replaces the slow excavation of meaning” (166). ultimately, for carr, it’s about who is controlling whom. while the internet may permit us to better perform some functions—search, for example—“it poses a threat to our integrity as human beings . . . we program our computers and thereafter they program us” (214). put another way, “the computer screen bulldozes our doubts with its bounties and conveniences. it is so much our servant that it would seem churlish to notice that it is also our master” (4). ■■ hamlet’s blackberry perhaps less familiar than carr’s work is william powers’ hamlet’s blackberry: a practical philosophy for building a good life in the digital age (harpercollins 2010). powers, a writer whose work has appeared in the washington post, the new york times, the new republic, and elsewhere, describes the influence of digital technology (or “screens,” to use his shorthand)3 and connectedness on our lives: in the last few decades, we’ve found a powerful new way to pursue more busyness: digital technology. computers and smart phones are often pitched as solutions to our stressful, overextended lives. . . . but at the same time, they link us more tightly to all the sources of our busyness. our screens are conduits for everything that keeps us hopping—mandatory and optional, worthwhile and silly. . . . marc truitteditorial: “the air is full of people” marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 4 information technology and libraries | march 2011 if not yet a general consensus, that people are coming to experience and understand these costs. finally, they also make the point that things need not continue on their present course. i can imagine that if we in libraries take carr and powers seriously, there might be significant implications for service models and collections practices. both books have been reviewed in all the usual mainstream places. remarkably though, to me—and excluding a scant few discussion list threads such as that on web4lib several years ago—i’ve seen no discussion in the usual professional venues of their implications where libraries are concerned. perhaps i’m simply not reading the “right” weblogs or discussion lists. i’m not under the illusion that libraries or librarians can by themselves alter our rush toward the “shallows.” still, given our eagerness to discuss how we extend the reach of “screens” in libraries—whether in the form of learning commons, wireless access, mobile-friendly websites, clearing stacks of “tree-books” in favor of e-books, etc.—would it not be reasonable to think that we should show as much concern about the consequences of such activities, and even some interest in providing possible remedial alternatives? one of my favorite library spaces in college was the linonia and brothers reading room in yale’s sterling memorial library (see a photo of the reading room at http://images.library.yale.edu/madid/oneitem.aspx ?id=1772930). its dark oak paneling, built-in bookshelves, overstuffed leather easy chairs, cozy alcoves, toasty, footwarming steam radiators, and stained-glass windows overlooking a quiet courtyard represented the epitome of the nineteenth-century “gentleman’s library” and encouraged the sort of deep reading and contemplation that are becoming so rare in our institutions today. i spent many hours there, reading, thinking, dreaming—and yes, catnapping too. i haven’t visited the “l&b” in years; i hope it is still the way i so fondly recall it. over the past few years, as we’ve considered the various aspects of the library-as-space question, we’ve created all manner of collaborative, group-focused, überconnected learning spaces. we’ve also created bookfree spaces (to say nothing of book-free “libraries”), food-friendly spaces, quiet and cell-phone-free spaces, and a host of others of which i’m sure i haven’t thought. so, in an attempt to get us thinking about what carr ’s and powers’ books might mean for libraries, here’s a crazy idea to start us off: how about a screen-free space for deep reading and contemplation? it should be very low-tech: no mobiles, no laptops, no desktops, no networks, no clickety-clack of keys, no chimes of incoming e-mail and tweets, no unearthly glow of monitors. no food, drink, or group-study areas, either. just a quiet, inviting, comfortable space for individual reading and the goal is no longer to be “in touch” but to erase the possibility of ever being out of touch. to merge, to live simultaneously with everyone, sharing every moment, every perception, thought, and action via our screens. even the places where we used to go to get away from the crowd and the burdens it imposes on us are now connected. the simple act of going out for a walk is completely different today from what it was fifteen years ago. whether you’re walking down a big-city street or in the woods outside a country town, if you’re carrying a mobile device with you, the global crowd comes along. . . . the air is full of people. (14–15) drawing inspiration and analogy from a list of philosophers and other historical and literary figures beginning with plato and ending with mcluhan, powers describes seven practical approaches, tools, and techniques for disconnecting from our screen-driven life: ■■ seek physical distance (plato) ■■ seek intellectual and emotional distance (seneca) ■■ hope for devices that might allow us to customize our degree of connectedness (gutenberg) ■■ consider older, low-tech tools as alternatives where possible (shakespeare via hamlet) ■■ create positive rituals (ben franklin) ■■ create a “walden zone” refuge (thoreau) ■■ be aware of and take personal control from technology by being aware of that technology (mcluhan) powers then reviews how he and his family used these techniques to regain the sense of control and depth they felt they’d lost to screens. in the past several months, i’ve tried a couple myself. i no longer carry a blackberry unless i’m traveling out of town. i avoid e-mail and the internet completely on saturdays (my “internet sabbath”). the effect of these two small and easily achieved changes has been little short of liberating, providing space to think and reflect without the distraction of always-on connectedness. walking my lab seamus has become a special pleasure! ■■ bringing libraries into the picture so, what do carr’s and powers’ theses mean for libraries, and what do they mean in particular for those of us who provide technology solutions for libraries? they remind us that there is a very real human cost to the technology of screens and always-on connectedness that have become our stock-in-trade in recent years. as well, they provide convincing evidence that there is a growing awareness, editorial | truitt 5 references and notes 1.

commitment to service that we’ve worked so hard to provide to those who wish to be collaborative and “always-on”? absolutely. no, we can’t change the world or stop the march of the screens. but perhaps, as with powers’ “walden zone,” we can start by providing a close-at-hand safe harbor for those of our patrons seeking refuge from the “always-on” world of screens. a file storage service on a cloud computing environment for digital libraries victor jesús sosa-sosa and emigdio m. hernandez-ramirez information technology and libraries | december 2012 34 abstract the growing need for digital libraries to manage large amounts of data requires storage infrastructure that libraries can deploy quickly and economically. cloud computing is a new model that allows the provision of information

open-source software. the authors evaluated performance and resource consumption using several levels of data availability and fault tolerance. this service can be taken as a reference guide for it staff wanting to build a modest cloud storage infrastructure. introduction the information technology (it) revolution has led to the digitization of every kind of information.1 digital libraries are appearing as one more step toward easy access to information spread throughout a variety of media. the digital storage of data facilitates information retrieval, allowing a new wave of services and web applications that take advantage of the huge amount of data available.2 the challenges of preserving and sharing data stored on digital media are significant compared to the print world, in which data “stored” on paper can still be read centuries or millennia later. in contrast, only ten years ago, floppy disks were a major storage medium for digital data, but now the vast majority of computers no longer support this type of device. in today’s environment, selecting a good data repository is important to ensure that data are preserved and accessible. likewise, defining the storage requirements for digital libraries has become a big challenge. in this context, it staff—those responsible for predicting what storage resources will be needed in the medium term—often face the following scenarios: • prediction of storage requirements turn out to be below real needs, resulting in resource deficits. • prediction of storage requirements turn out to be above real needs, resulting in expenditure and administration overhead for resources that end up not being used. in these situations, considering only an efficient strategy to store documents is not enough.3 the acquisition of storage services that implement an elastic concept (i.e., storage capacity that can be victor jesús sosa-sosa (vjsosa@tamps.cinvestav.mx) is professor and researcher at the information

technology and libraries | december 2012 35 increased or reduced on demand, with a cost of acquisition and management relatively low) becomes attractive. cloud computing is a current trend that considers the internet as a platform providing on-demand computing and software as a service to anyone, anywhere, and at any time. digital libraries naturally should be connected to cloud computing to obtain mutual benefits and enhance both perspectives.4 in this model, storage resources are provisioned on demand and are paid according to consumption. services deployment in a cloud-computing environment can be implemented three ways: private, public, or hybrid. in the private option, infrastructure is operated solely for a single organization; most of the time, it requires an initial strong investment because the organization must purchase a large amount of storage resources and pay for the administration costs. the public cloud is the most traditional version of cloud computing. in this model, infrastructure belongs to an external organization where costs are a function of the resources used. these costs include administration. finally, the hybrid model contains a mixture of private and public. a cloud-computing environment is mainly supported by technologies such as virtualization and service-oriented architectures. a cloud environment provides omnipresence and facilitates deployment of file-storage services. it means that users can access their files via the internet from anywhere and without requiring the installation of a special application. the user only needs a web browser. data availability, scalability, elastic service, and pay-per-use are attractive characteristics found in the cloud service model. virtualization plays an important role in cloud computing. with this technology, it is possible to have facilities such as multiple execution environments, sandboxing, server consolidation, use of multiple operating systems, and software migration, among others. besides virtualization technologies, emerging tools that allow the creation of cloud-computing environments also support this type of computing model, providing dynamic instantiation and release of virtual machines and software migration. currently, it is possible to find several examples of public cloud storage, such as amazon s3 (http://aws.amazon.com/en/s3), rackspace (http://www.rackspace.com/cloud/public/files), and google storage (https://developers.google.com/storage), each of which provide high availability, fault tolerance, and services and administration at low cost. for organizations that do not want to use a third-party environment to store their data, private cloud services may offer a better option, although the cost is higher. in this case, a hybrid cloud model could be an affordable solution. organizations or individual users, can store sensitive or frequently used information in the private infrastructure and less sensitive data in the public cloud. the development of a prototype of a file-storage service implemented on a private and hybrid cloud environment using mainly free and open-source software (foss) helped us to analyze the behavior of different replication techniques. we paid special attention to the cost of the system implementation, system efficiency, resource consumption, and different levels of data privacy and availability that can be achieved by each type of system. http://aws.amazon.com/en/s3 http://www.rackspace.com/cloud/public/files https://developers.google.com/storage a file storage service on a cloud computing environment for digital libraries | sosa-sosa 36 infrastructure description the aim of this prototyping project was to design and implement scalable and elastic distributed storage architecture in a cloud-computing environment using free, well-known, open-source tools. this architecture represents a feasible option that digital libraries can adopt to solve financial and technical challenges when building a cloud-computing environment. the architecture combines private and public clouds by creating a hybrid cloud environment. for this purpose, we evaluated tools such as kvm and xen, which are useful for creating virtual machines (vm).5 open nebula (http://opennebula.org), eucalyptus (http://www.eucalyptus.com), and openstack (http://www.openstack.org) are good, free options for managing a cloud environment. we selected open nebula for this prototype. commodity hard drives have a relatively high failure rate, hence our main motivation to evaluate different replication mechanisms, providing several levels of data availability and fault tolerance. figure 1(a) shows the core components of our storage architecture (the private cloud), and figure 1(b) shows a distributed storage web application named distributed storage on the cloud (disoc), used as a proof of concept. the private cloud also has an interface to access a public cloud, thus creating a hybrid environment. figure 1. main components of the cloud storage architecture the core components and modules of the architecture are the following: • virtual machine (vm). we evaluated different open-source were evaluated, such as kvm and xen, for the creation of virtual machines.6 some performance tests were done, and kvm showed a slightly higher performance than xen. we selected kvm as the main virtual machine manager (vmm) for the proposed architecture. vmms also are called http://opennebula.org/ http://www.eucalyptus.com/ http://www.openstack.org/ information technology and libraries | december 2012 37 hypervisors. each vm has a linux operating system that is optimized to work in virtual environments and requires a minimum consumption of disk space. the vm also includes an apache web server, a php module, and some basic tools that were used to build the disoc web application. every vm is able to transparently access a pool of disks through a special data access module, which we called dam. more details about dam follow. • virtual machine manager module (vmmm). this has the function of dynamic instantiation and de-instantiation of virtual machines depending on the current load on the infrastructure. • data access module (dam). all of the virtual disk space required by every vm was obtained through the data access module interface (dam-i). dam-i allows vms to access disk space by calling dam, which provides transparent access to the different disks that are part of the storage infrastructure. dam allocates and retrieves files stored throughout multiple file servers. • load balancer module (lbm). this distributes the load among different vms instantiated on the physical servers that make up the private cloud. • load manager (lm). this monitors the load that can occur in the private cloud. • distributed storage on the cloud (disoc). this is a web-based file-storage system that is used as a proof of concept and was implemented based on the proposed architecture. replication techniques high availability is one of the important features offered in a storage service deployed in the cloud. the use of replication techniques has been the most useful proposal to achieve this feature. dam is the component that provides different levels of data availability. it currently includes the following replication policies: no-replication, total-replication, mirroring, and ida-based replication. • no-replication. this replication policy represents the data availability method with the lowest level of fault tolerance. in this method, only the original version of a file is stored in the disk pool. it follows a round-robin allocation policy whereby load assignation is made based on a circularly linked list, taking into account disk availability. this policy prevents all files from being allocated to the same server, providing a minimal fault tolerance in case a server failure. • mirroring. this replication technique is a simple way to ensure higher availability without high resource consumption. in this replication, every time a file is stored in a disk, the dam creates a copy and places it on a different disk. • total-replication. this represents the highest data availability approach. in this technique, a copy of the file is stored on all of the file servers available. total-replication also requires the highest consumption of resources. • ida-based replication. to provide higher data availability with less impact on the consumption of resources, an alternative approach based on information-dispersal techniques can be used. the information dispersal algorithm (ida) is an example of this a file storage service on a cloud computing environment for digital libraries | sosa-sosa 38 strategy.7 when a file (of size |f|) is required to be stored using the ida, the file is partitioned into n fragments of size |f|/m, where m<n. these fragments are distributed in n different disks. the ida only needs to obtain m fragments to reconstruct the original file. in this context, even if n-m disks failed, the file would still be recovered. it is desirable that no more than n-m file servers fail. the ida provides better fault tolerance than mirroring without the need to completely replicate the original file. in this prototype, the ida was evaluated with n=5 and m=3 (which means only 60 percent of the original file was replicated). the ida is attractive for a hybrid cloud environment because it is not necessary to save the entire file on a single file server (disk). in this way, it could be possible to send k fragments of the file (where k<m) to a public cloud storage without revealing the complete content of the original file. this strategy works similar to redundant array of independent disks (raid) 5 in that it is a type of block-level striping storage technology, which distributes parity or data about the data along with the data itself.8 however, the ida uses a different strategy for data reconstruction and could be implemented in a distributed environment using from 2 to n storage servers. performance evaluation we implemented and used a prototype of this architecture as the evaluation scenario. it includes five commercial pcs (commodity), whose characteristics are shown in the first section of table 1. the features of the vms that were instantiated on these pcs are shown in the second section of table 1. physical machines pcs cores memory hard disk network 1 pc 4 4 gb 640 gb ethernet 10/100 4 pc 2 2 gb 250 gb ethernet 10/100 virtual machines 8 vm 1 1 gb 1 gb virtual ethernet 1 vm 1 128 mb 1 gb virtual ethernet table 1. characteristics of the physical pcs and vms used in the private cloud we created nine vms in a private cloud environment for this evaluation. to build and test a hybrid cloud environment, it was necessary to access a public-storage cloud (third-party infrastructure). we used two public storage providers in this experiment: dropbox and phoenix (also known as treestore).9 dam also was responsible for offering transparent access to the external storage infrastructure. both providers required valid user credentials on a per-request basis. the dropbox information technology and libraries | december 2012 39 api additionally requires a developer key. it is relevant to note that dropbox also is able to keep files in the amazon s3 storage infrastructure. we emulated different workloads, running concurrent client applications that sent many parallel file upload and download requests to our cloud-storage prototype. the private-storage cloud configuration was first tested by receiving 50, 100, and 150 parallel requests. it is worth mentioning that when testing the hybrid cloud configuration, it was not possible to send the same number of parallel requests used in the private configuration. it was necessary to decrease this number because the public cloud-storage providers (dropbox and treestore) could view parallel requests of the same number as an attack against their servers and, consequently, block the service. since we were more interested in having a hybrid cloud scenario than in comparing public vs. private cloud, we decided to send only 10, 20, and 30 parallel requests to the public storage in the hybrid cloud configuration. the private and hybrid (private + public) cloud-storage scenario was designed to evaluate the impact of having an elastic service and the behavior of the cloudstorage infrastructure when applying different replication techniques to offer several levels of data availability. the impact of having an elastic service this section presents a comparison between an elastic storage service (using virtual machines) and a fixed storage service (using only a physical machine). in the elastic service, a new vm is instantiated when a workload exceeds a defined upper threshold. in the opposite situation (when the response time is shorter than a lower threshold), a vm is released. several response-time restrictions were configured during this evaluation to determine the best time to instantiate or release a vm. the evaluation used different workloads generated by autobench.12 a physical machine with a single hard disk receiving an increasing workload was compared with the same physical machine that incrementally instantiated a set of vms running the same workload. for this test, the workload consisted of a set of requests of a dynamically generated php webpage. this webpage emulated the processing time on a server by running a sorting algorithm (bubble type). different levels of load were emulated by sending variable-size lists of elements that had to be sorted by the server process. the results are shown in figure 2. the vertical axis represents the average response time (in seconds) after sending different requests to the storage service. the horizontal axis represents the evaluation time (500 seconds), which was the period of time different clients were sending requests to the storage service. the fixed line indicates the performance when the service load balancer accessed one physical machine (i.e., the fixed storage service). the elastic line represents the performance when the service load balancer accessed one to three vm instantiations in the same physical machine (i.e., the elastic service). the instantiation and activation time (called the deployment time) of a new vm was between sixty and ninety seconds. at the beginning of the test, when the workload is low, the response time offered by the fixed service (running only on one physical machine) is better—in some cases up to four or five orders of magnitude—than that obtained in the execution of the service accessing only one virtual a file storage service on a cloud computing environment for digital libraries | sosa-sosa 40 machine. however, the elastic service improved the response time by including more vms in the same physical machine. figure 2. performance comparison between a fixed and elastic storage service response times of fifteen seconds and five seconds were defined as the upper and lower threshold, respectively. figure 2 shows how the response time in the elastic service had a considerable reduction over the course of the test. this behavior was caused by the new vms that were instantiated in the storage service and taken into account by the load balancer. at the end of this evaluation, the elastic service was able to finish the workload offering good response times, while the fixed service collapsed and could not finish all of the requests sent by the client. evaluation of different replication techniques with dam, it is possible to define the level of data availability in the cloud-storage prototype by applying different replication techniques. we defined a benchmark to evaluate the benefits when using a distributed storage system compared with a centralized version. in the centralized version, dam had access to a single disk using only one vm (emulating a centralized process) with a single file server (emulating centralized storage). the distributed version considered the use of distributed processes (eight vms) accessing a distributed storage system (five disks distributed on different storage servers encapsulated by dam). since the replication with the ida technique is attractive for a hybrid cloud service, its behavior was compared in both cases: when it is only accessing a private storage cloud and when it is accessing both a private and a public storage cloud (hybrid model). two main metrics were taken into account for these experiments. the first was response time, the time from when the user clicks on the button to upload or download a file to when the file loading or downloading has finished—in this test until the tcp connection is closed. the second information technology and libraries | december 2012 41 was service time, the time needed by dam to locate a file (or part of it) and prepare the file to be read by the system component that is requesting it. replication techniques in a private cloud this test evaluated the storage service response and service time using different levels of data availability and fault tolerance on a private cloud environment. we implemented different replication techniques in dam to carry out this task. the left side of the figure 3 shows the response and service time produced by different replication techniques during the file uploading process. in this case, even though the total replication technique had a poor service time, the storage service showed its worst performance when implementing a centralized architecture. it is interesting to see how the no-replication technique is showing the best performance during the uploading process. this behavior may exist because this technique does not require any additional work for replicating a file and does not have to send any additional data through the network. figure 3. average response and service time for file uploading (fu) and downloading (fd) using different replication techniques in a private cloud environment the right side of figure 3 shows the response and service time perceived during the file downloading process using the private cloud. in this case, even though the ida technique is producing the worst service time, the response time showed by the different replication techniques was similar. the ida shows a competitive response time and offers an acceptable level of fault tolerance. the total replication technique offers high data availability and fault tolerance, but it is not producing the best response time. this slowness could be because the way dam is managing the distributed disk pool. it is important to note that this replication technique produces the highest storage consumption. a file storage service on a cloud computing environment for digital libraries | sosa-sosa 42 replication techniques in a hybrid cloud the aim of this test was to evaluate the behavior of the ida replication technique implemented in a hybrid cloud (accessing both private and public cloud infrastructures). in this context, we generated fewer requests than we originally planned because of restrictions made by the public storage providers. it is important to note that the ida technique could be attractive in hybrid cloud storage. the ida offers data availability, fault tolerance, and a certain level of privacy because it does not require a copy of a complete file to be sent to the public cloud storage. in this context, we compared the response and service times during the file uploading and downloading processes. the performance of the version of the ida implemented in the private cloud is taken as a reference point. we compared the private version two ida versions that access each public cloud storage provider, dropbox and phoenix (treestore). the left side of figure 4 shows the response and service time during the uploading process. the figure shows that the ida suffers a high penalty when accessing external storage (up to ten orders of magnitude). even when the downloading process (right side of figure 4) showed better performance, the response time of the ida is still penalized when accessing external storage in range of six or seven orders of magnitude. this penalty on the ida version in a hybrid environment mainly is caused, we think, by a poor internet connection (it is not a dedicated link) used to send and receive file fragments from the external infrastructure (storage providers). it is worth keeping in mind that one of the benefits of storing some file fragments in the external infrastructure is having more storage space available in the private cloud. it also is important to remember that, for security reasons, the number of fragments sent to the public infrastructure will never be greater than or equal to m, where m is the number of pieces required to build the original file. figure 4. average response and service time for file uploading (fu) and downloading (fd) in the evaluation of the hybrid cloud information technology and libraries | december 2012 43 for testing the behavior of this version of the ida, dam always had to obtain a fragment of a file from the public cloud (external providers). it should be noted that this is not the typical case; in a real scenario, the hybrid version of the ida only would obtain a fragment of a file from the public cloud when the dam couldn’t obtain the m needed fragments from the private cloud, which means that more than n-m disks had failed (worst case). the two public storage providers showed similar performance. however, the behavior of dropbox was slightly better than treestore. this could be because of the maturity of the dropbox api or because of a better network connection to the dropbox sites. related work amazon s3 is considered a pioneer of cloud storage solutions. data storage rates vary according to the amount of data stored and on the availability required by users. data availability relates to the replication technique the amazon infrastructure uses.10 there also are solutions that take advantage of public cloud storage using replication techniques based on raid, for example redundant array of cloud storage (racs), a proxy located between multiple cloud storage providers and customers.11 racs distributes data in a way that provides an opportunity for clients to tolerate interruptions in a public cloud storage service or when the price for using such services gets too high. it uses replication to support such sit uations. racs offers to its users an interface similar to amazon s3, allowing operations such as put, get, delete, and list. another such service is high-availability and integrity layer (hail), a cryptographic distributed system that allows file servers to provide a secure storage environment.12 hail supports the failure of any of the servers that make up the system, adding a degree of security to stored data using an approach based on the reed solomon (rs) error correction codes.13 the rs codes describe a systematic way of building codes that could detect and correct multiple random symbol errors by adding additional check symbols to the data. public cloud-storage infrastructures such as amazon 3, rackspace, and google storage are being used by distributed file systems such as dropbox (http://www.dropbox.com), wuala (http://www.wuala.com), and adrive (http://www.adrive.com), which allow users to store and share files through web applications.14 a commonality between these infrastructures and applications is their use of public clouds. these services are helpful for users wanting to have unlimited storage space with which to back up their data. however, the use of these types of solutions can be challenging in a business environment. the fears that some organizations have about storing sensitive data in a public infrastructure or about future data availability are issues that discourage the use of such third-party infrastructure. our approach suggests a viable option is creating a hybrid cloud storage environment (private + public) based on low cost infrastructure in which only part of the stored data are in the public environment, thereby minimizing the likelihood of unauthorized access. http://www.dropbox.com/ http://www.wuala.com/ http://www.adrive.com/ a file storage service on a cloud computing environment for digital libraries | sosa-sosa 44 conclusions digital-data preservation represents a threat to digital libraries. data are an essential part of a library, and its storage is of the utmost importance. digital-data storage requires extreme durability and scalability. however, component failures, obsolescence, human-operation errors, natural disasters, attacks, or management errors are some common difficulties that must be carefully studied when implementing a digital library. these threats may be minimized using a distributed data-storage approach. in this area, cloud computing may help, as both the storage and the services are completely distributed. this paper presented a comparison of different replication techniques implemented in a private and hybrid cloud-storage infrastructure. we described the components of this infrastructure and demonstrated that it is possible to improve the time of system deployment and performance when elastic services (virtualized) are implemented on physical machines. we illustrated how to optimize the use of physical machine resources, especially when running systems (like the storage service) with an unpredictable workload. the replication techniques evaluated in this paper were implemented in a data access module called dam. dam is a simple mechanism for storage consolidation on a private and hybrid cloud environment, and it is able to offer different levels of data availability based on user requirements. it uses a lightweight algorithm for file allocation, reducing the amount of metadata needed with low resources consumption. we showed how a hybrid cloud environment, implemented with freely available software tools, can be a good solution for those institutions not confident storing sensitive data in public storage clouds and those institutions having economic and technical limitations for building their own private cloud. the prototype described in this paper showed how feasible it is to build a modest private cloud and combine it with a consolidated public cloud. in this context, this paper showed how the use of a replication technique based on an ida has the benefits of the public cloud storage without exposing the complete content of files via a thirdparty infrastructure. references 1. john f. gantz et al., “the expanding digital universe: a forecast of worldwide information growth through 2010,” an idc white

 is  ar,  really?  ronald  azuma,  a  pioneer  and  innovator  in  the  research  and  creation  of  ar   applications,  describes  ar  as  a  supplement  to  reality.9  it  combines  the  real  and  the  virtual,  aligning   the  virtual  with  the  real  environment.10  ar  is  part  of  a  mixed  reality  continuum,  and  “the   technology  depends  on  our  ability  to  make  coherent  space  from  sensory  information.”11  this   coherent  space  is  dependent  on  several  variables,  one  of  which  is  ar’s  real-­‐time  interactivity.  ar   applications  cannot  experience  any  delays  in  response  time;  if  the  real  and  virtual  are  misaligned,   it  impedes  the  sense  of  reality.  ar  needs  to  happen  at  the  same  speed  as  real  life—virtual  actions   coinciding  with  human  actions,  and  variable  across  users.   some  also  view  ar  as  a  new  media  experience,  adding  to  the  growing  list  of  digital  literacies.   “while  the  pure  technology  provides  a  set  of  features  that  can  be  exploited,  the  features  of  the  new   technology  will  develop  into  one  or  more  particular  forms  within  a  particular  historical  and   cultural  setting.”12  this  includes  “remediating”  existing  media,  such  as  film  or  stage  productions,   with  ar  components.   as  a  result,  ar  is  contextual  and  reliant  on  each  personal  experience,  but  it  also  borrows  from   earlier  forms  of  media  within  those  contexts  and  experiences.  for  this  reason,  it  is  important  to   examine  just  how  those  within  lis  are  constructing  ar  as  a  concept.  the  rapid  pace  at  which  ar  is   evolving  and  gaining  in  popularity  suggests  those  within  the  field  of  lis  will  need  to  be  aware  of   new  applications  for  the  technology  as  more  and  more  users  may  come  to  expect  access  to  and   knowledge  of  this  technology.   much  of  the  literature  also  references  ar  as  being  an  enhancement.  but  what,  exactly,  is  ar   enhancing?  the  answer  includes  our  senses  and  perceptions,13  software,14  our  emotions  and   feelings,15  and  question-­‐answering  programs.16  authors  use  the  term  enhancement  with  no   explanation  of  how  it  is  defined  in  each  piece  of  literature.  some  assume  more  is  always  better.   missing  is  the  voice  of  the  user  or  consumer,  whom  authors  refer  to  as  a  subject  or  wearer.  the   irony  is  many  of  these  users  are  the  ones  creating,  building,  and  populating  these  ar  worlds.  i   propose  the  field  of  lis  is  in  a  prime  position  to  address  the  missing  piece  of  the  research  and   discourse  of  ar.     information  technology  and  libraries  |  december  2014   25   many  of  the  technological  enhancements  authors  describe  in  the  ar  literature  connect  to  the   development  of  knowledge,  one  of  the  main  goals  of  computing.17  there  are  a  variety  of  settings  in   which  some  expect  ar  to  create  new  routes  to  knowledge.  within  a  library  setting,  ar  can   improve  library  instruction,18  provide  information  retrieval  about  shelved  books  through   recognition  applications,19  reconstruct  and  restore  artifacts,20  and  deliver  services  at  point  of  need   through  qr  codes.21  others  view  ar  as  a  technological  breakthrough  with  extreme  potential  in   medical  fields,  such  as  non-­‐invasive  surgical  visualization,  which  can  display  the  organs  through   sensors  placed  on  the  body,  helping  medical  practitioners  and  students  to  understand  internal   body  functions.22   ar  is  also  said  to  perform  some  of  its  “enhancements”  in  the  classroom.23  augmented  books  are   growing  in  number  and  are  expected  to  enhance  collaboration  and  interactivity  between  students.   some  allow  more  than  one  person  to  explore  the  same  content  at  the  same  time  or  outside  of  the   classroom  through  mobile  technology;  others  give  students  the  ability  to  rotate,  tilt,  and   manipulate  viewing  angles  of  various  objects.24       ar  technology  within  art  education  is  said  to  have  a  positive  impact  on  student  motivation.25  in  a   2010  study,  reference  librarians  at  the  university  of  manitoba  were  given  smartphones  and  asked   to  create  innovative  projects.  what  they  came  up  with  resulted  in  a  public  art  project  using  social   networks,  gps  software,  and  ar  technology  that  allowed  users  to  interact  with  the  art  pieces   through  qr  codes.26  again  and  again,  interactivity,  connectivity,  and  mobility  of  ar  applications   are  highlighted  as  efficient  and  motivating  factors  in  education  and  learning.27,28,29,30   organizations  are  also  testing  ar  applications  for  general  public  use.  museums  and  galleries   contain  ar  virtual  displays  of  artifacts  and  historic  scenes,  personalizing  interactive  experiences   and  providing  multiple  perspectives  of  events  and  artifacts.31  the  natural  history  museum  in   london,  for  example,  created  the  attenborough  studio  in  2009  for  live  events  and  the  viewing  of   ar  enhanced  films.32  ar  tours  are  also  offered  on  historic  places  and  spaces.  augmented  reality  is   already  in  use  as  a  tour  guide  application,33  to  supplement  paper  maps,34  and  even  to  reconstruct   damaged  historic  sites.35  ar  is  essentially  a  mutable  form  of  displaying  what  are  typically  static   objects  and  ideas.   the  use  of  ar  is  integrative.  it  can  saturate  real  landscapes,  places,  and  spaces  with  virtual   characteristics;  it  can  add  to  or  hide  objects  in  the  environment.36  manipulation  of  the   environment  promotes  “immersive  experiences,”37  multifaceted  for  different  people  interacting   with  ar.38  virtual  experiences  are  expected  to  enhance  the  real-­‐life  experiences  of  the  user.  spaces   can  become  layered,  or  scaffold,  not  only  through  depth  perception  or  ar  software,  but  also   through  the  user’s  contextual  life  experiences.39   with  growing  widespread  use,  it  is  imperative  for  those  in  the  field  of  lis  to  understand  this   technology  and  how  it  is  used.  how  will  these  applications  be  archived?  will  institutions  and   organizations  collaborate  with  users  in  creating  these  applications?  will  users  expect  librarians   and  other  knowledge  workers  to  help  them  understand  and  use  the  technology?  will  libraries  and     do  you  believe  in  magic?  |  zak       26   other  institutions  use  the  technology,  and  if  so,  in  what  capacity?  these  are  just  some  of  the   questions  lis  professionals  should  be  asking  to  ensure  they  are  meeting  user  needs  in  relation  to   technology  and  the  access  of  information  through  technology.  this  study  provides  a  base  for   considering  these  questions,  and  the  effects  of  ar,  by  situating  the  concept  and  expectations  of  ar   within  the  field  and  aligning  the  conceptualization  with  radical  change  theory.   the  user  within  ar  and  lis   the  use  of  ar  can  bring  with  it  an  altering  of  emotional  and  psychological  experiences.  pederson   argues  ar  applications  should  be  “human-­‐centric”.40  because  human  beings  “instrumentalize”   technology  such  as  ar,  the  technology  itself  should  accommodate  the  human  needs  for  ar  tools.41   for  ar  applications  to  be  successful,  they  must  display  the  human  characteristics  encompassing   reactions  to  one  another  and  the  environment.42  applications  blurring  the  lines  between  the  real   and  the  virtual,  and  engaging  the  person  in  ways  that  play  on  perception,  are  capable  of  changing   the  real-­‐life  perceptions  and  expectations  of  the  user.  ar  can  be  either  a  form  of  escapism  for  brief   moments  or  an  escape  from  what  we  know  of  as  real-­‐life  for  good.43   what  much  of  the  research  assumes  is  the  desire  for  ar  applications.  lacking  is  surveys  of  user   desire  for  ar,  or  examination  of  potential  negative  consequences.  a  user-­‐focus  is  central  to  lis   and  the  values  of  librarianship.  within  all  these  potential  uses,  what  is  not  being  discussed  is  how   creators  of  ar  applications  organize,  categorize  and  choose  the  information  contained  within   these  applications.  much  of  the  discussion  surrounding  the  implications  of  ar  use  is  left  to  those  in   fields  of  philosophy  and  psychology,  dealing  in  abstraction.  the  research  and  marketing  of  ar   applications  promote  passive  acceptance  of  ar  technologies.44  there  comes  a  point  when  ar   researchers  must  ask,  to  what  extent  are  potential  users  aware  of  and  desirous  of  ar  applications?   the  notion  of  people  as  users  is  quite  similar  to  the  contextualization  of  human  as  subject  in  this   scientific  literature,  different  from  the  notion  of  user  in  lis.  in  computer-­‐science  literature,  users   are  those  reacting  to  ar  and  providing  ar  researchers  with  content  for  ar  modification  as   evaluators  of  the  technology.  within  computer-­‐science  literature,  there  is  much  talk  of  the  user’s   satisfaction  with  tested  ar  applications;45  there  also  much  talk  of  the  user’s  position  within  the  ar   frame/environment.46  similar  is  the  discussion  of  the  user  and  the  physical  space  of  the  ar   application,  and  how  the  user  responds  to  the  ar  functions.47  user  and  subject  are  terms  used   interchangeably  in  the  scientific  literature.  these  terms  are  largely  undefined,  indicating  little   regard  for  the  role  of  the  human  outside  of  objectification  as  a  tool  working  in  the  ar  environment.   within  the  field  of  lis,  the  notion  of  the  user  takes  on  different  characteristics:  users  are  clearly   patrons,  human  beings,  for  which  lis  provides  a  service.  kuhlthau  focuses  on  user-­‐centric   treatment  of  information  services  with  her  information  search  process  model.48  chatman’s   theories  of  information  poverty  and  life  in  the  round  both  center  on  the  information-­‐seeking   behaviors  of  ordinary  people  with  everyday  needs.49     information  technology  and  libraries  |  december  2014   27   library  anxiety,  as  developed  by  mellon,  pivots  on  the  emotions  and  psychological  responses  of   information-­‐seekers,  or  users.50  there  are  many  more  theories  and  models  demonstrating  this   user-­‐centric  focus  in  lis.  case  points  to  dervin’s  1976  article  “strategies  for  dealing  with  human   information  needs:  information  or  communication?”  as  an  exemplar  of  the  shift  in  thinking  about   the  role  and  needs  of  the  user  in  lis.51  dervin  pointed  to  assumptions  in  research  on  information-­‐ seeking,  such  as  more  information  as  better,  and  relevant  information  existing  for  every  need.  it  is   important  to  note  whether  there  are  assumptions  now  being  made  in  lis  literature  with  regard  to   user  interaction  with  ar  and  how  best  to  understand  user-­‐centered  design  of  ar  applications.   bowler  et  al.  define  user-­‐centered  design  as  “[reflecting]  the  user,  typically  from  a  cognitive,   affective  or  behavioral  point  of  view,  as  well  as  the  social,  organizational,  and  cultural  contexts  in   which  users  function.”52  these  points  of  view—the  cognitive,  social,  behavioral,  and  the  like—all   synchronize  within  ar  applications.  bowler  et  al.  state,  “with  the  increased  use  of  digital,   networked  information  tools  in  daily  practice  and  the  emergence  of  the  digital  library  and  archive,   it  is  impossible  to  separate  the  service  from  the  system.  in  this  context,  understanding  the  user   becomes  more  critical  than  ever.”53  with  the  advent  of  ar  and  its  dependence  on  user  interaction,   it  is  imperative  to  continue  to  address  the  role  of  the  user.   o’brien  and  toms  further  the  discussion  by  trying  to  define  user  engagement  with  technology.  the   authors  define  engagement  as  a  process,  composed  of  three  states:  a  point  of  engagement,  a  period   of  engagement  and  then  finally  disengagement.54  attention  to  user  needs  and  behavior  as  an   individualized  process  is  evident  across  lis  literature.  shu  suggests  user  engagement  in  website   design  as  a  means  to  strengthening  user  relationships  with  organizations  through  a  study  of  web   2.0  [interactive  internet  applications].55  idoughi,  seffah,  and  kolski  recommend  integrating   “personae,”  or  perceived  personality  types  and  characteristics,  into  user-­‐design  to  address   challenges  in  creating  software  offering  highly  personalized  services.56  pang  and  schauder  take  a   community-­‐based  approach  to  systems  design,  particularly  in  libraries  and  museums  and   encourage  system  designers  to  draw  on  the  study  of  relationships  and  interaction  within  different   communities  as  a  means  to  gain  insight  into  more  user-­‐centric  design  methods.57   a  user-­‐centric  focus  has  extended  itself  to  catalog  design58  and  information-­‐retrieval  systems   design.59  it  has  been  applied  as  a  learning  approach  to  organizational  culture  within  libraries.60   scholarly  research  within  the  library  is  said  also  to  have  benefitted  because  a  user-­‐centric  focus   informs  how  different  types  of  users  interact  with  information  within  the  library.61  through  an   analysis  of  user  language,  user-­‐centricity  is  also  applied  as  a  means  to  identify  strategies  for   creating  language  tools  for  web  searching.62  such  studies  are  representative  of  the  ways  a  user-­‐ centric  paradigm  proliferates  within  lis.   these  models  and  studies  highlight  the  importance  of  the  user  perspective  and  how  the  user   engages  with  information  at  various  levels.  radical  change  theory  (rct),  developed  by  eliza   dresang  in  1999,  goes  one  step  further  and  adds  another  element  to  the  user-­‐information   interaction:  the  user’s  interaction  with  other  users  and  the  response  to  the  interactive  applications     do  you  believe  in  magic?  |  zak       28   and  digital  technologies  in  which  information  is  becoming  embedded.  this  element  is  mirrored  in   such  applications  as  twitter  and  foursquare,  which  allow  digital  overlays  of  information  to  see  if   there  are  individuals  “near  you”  also  logged  on  to  these  networking  applications.   the  highly  complex  ar  applications  call  for  a  highly  complex  view  of  human  interaction  with  those   applications.  radical  change  theory  helps  to  explicate  the  characteristics  of  human  expectations   and  interactions  with  information  in  digital  formats.  coupled  with  an  examination  of  ar  discourse   within  lis  literature,  rct  helps  clarify  how  people,  or  users,  are  approaching  the  changing   information  landscape.   research  approach   this  study  focuses  on  the  user-­‐centric  paradigm  prevalent  in  lis,  seeking  to  understand  the   relationship  between  the  conceptualization  of  an  emerging  technology  and  the  role  of  the  user.   the  research  questions  guiding  this  study  are  the  following:   • how  is  augmented  reality  (ar)  conceptualized  in  lis?   • what  is  the  role  of  the  user  in  relation  to  ar  as  it  is  conceptualized  in  lis?     the  aim  is  to  understand  how  a  specifically  lis  user-­‐centric  focus  can  apply  to  the   conceptualization  of  ar  and  its  use  within  libraries  and  cultural  heritage  institutions.   the  model  for  this  study  is  clement  and  levine,  which  examined  how  pre-­‐1978  dissertations  were   published  and  what  the  concept  of  copyright  was  for  those  dissertations.  the  unit  of  sampling  in   their  study  was  the  written  message,  “defined  as  a  complete  statement  or  series  of  statements   with  a  distinct  start  and  end.”  each  message  under  investigation  required  author-­‐specified   semantic  concepts.  the  researchers  then  selected  recording  units,  what  they  describe  as  “explicit   assertions”  pertaining  to  the  publication  of  dissertations.  the  authors  delineated  explicit   assertions  as  taking  several  forms,  from  a  phrase  within  a  sentence  to  a  multipage  argument.63   for  the  purpose  of  this  study,  i  investigated  written  messages  contained  in  the  journals  and  blog   posts  i  chose  as  well  as  links  to  other  webpages  or  blog  posts  contained  in  the  initial  data  set.  the   semantic  concept  is  the  term  augmented  reality.  the  recording  unit  is  any  explicit  assertions  made   regarding  augmented  reality  using  the  same  range  of  form  as  clement  and  levine.64   in  this  study,  i  allied  content  analysis  with  radical  change  theory  (rct).  rct  focuses  on  the   characteristics  of  interactivity,  connectivity,  and  access,  which  are  all  dependent  on  measures  of   human  connections  through  various  forms  of  media.  the  characteristics  of  these  principles  are  as   follows:   • interactivity  refers  to  dynamic,  user-­‐initiated,  nonlinear,  nonsequential,  complex   information  behavior,  and  representation.       • connectivity  refers  to  the  sense  of  community  or  construction  of  social  worlds  that  emerge   from  changing  perspectives  and  expanded  associations.         information  technology  and  libraries  |  december  2014   29   • access  refers  to  the  breaking  of  long-­‐standing  information  barriers,  bringing  entrée  to  a   wide  diversity  of  opinion  and  opportunity.65   content  analysis  of  lis  literature  related  to  ar  through  the  rct  framework  allowed  me  to  find   connections  between  the  conceptualization  of  a  technology  and  how  the  conceptualization   functions  within  a  given  academic  community.  during  the  data  analysis,  i  assessed  whether  the   characteristics  of  interactivity,  connectivity,  and  access  are  present  in  the  descriptors  of  ar.   understanding  how  ar  is  brought  into  the  discourse  of  lis  in  lis  literature  helps  describe  the   ways  an  emerging  technology  is  developed  as  a  concept  and  as  a  tool  through  an  examination  of   how  researchers  and  practitioners  perceive  the  need  for  and  use  of  ar.   data  collected  from  searches  of  google  blogs  and  the  library,  information  science  and  technology   abstracts  with  full  text  (lista)  database  aided  in  understanding  the  conceptualization  of  ar  and   the  role  of  the  user  in  relation  to  the  conceptualization.  all  the  searches  took  place  over  three   months,  december  2012  to  february  2013,  and  all  searches  centered  on  the  search  term   “augmented  reality”  (the  term  was  enclosed  in  quotation  marks  in  the  search  box).   through  purposeful  criterion  sampling,  all  search  results  including  the  term  “augmented  reality”   are  included  in  the  initial  list  of  data  for  analysis.  i  chose  the  google  blogs  search  engine  because   of  its  popularity,  familiarity,  ease  of  use,  and  variety  of  viewpoints.  blogs  are  an  important  source   of  data  because  they  continue  to  increase  in  popularity  across  disciplines,  including  lis,  and  serve   as  a  way  for  people  to  communicate  with  one  another  and  exchange  information.66  the  lista   database  is  easy  to  access;  provided  free  to  libraries;  familiar  to  students,  faculty,  and   professionals  in  the  field  of  lis;  and  covers  a  broad  spectrum  of  general  and  specialized  journals.   together,  search  results  comprise  both  academic  and  popular,  or  mainstream,  sources.   google  blogs   i  first  gathered  data  from  searches  of  google  blogs.  i  conducted  two  separate  searches  of  the   search  term  “augmented  reality.”  the  first  was  in  december  2012  and  the  second  was  in  february   2013.  the  first  search  yielded  373  results  and  the  second  yielded  376.  i  used  the  advanced  search   function  to  limit  the  search  to  blog  postings  between  june  2012  and  december  2012.  the  second   search  is  limited  to  june  2012  to  february  2013.  blog  postings  excluded  from  the  final  body  of   data  for  analysis  include  foreign-­‐language  entries,  duplicate  items,  video-­‐only  postings,  and   advertisements,  resulting  in  a  final  data  set  of  300  postings.   library,  information  science  and  technology  abstracts  with  full  text  (lista)   after  completing  my  search  of  google  blogs,  i  gathered  data  from  lista  database  searches.  i   searched  the  database  once  a  month  for  three  months,  from  december  2012  to  february  2013.  i   divided  each  monthly  search  into  three  search  types:  first  by  author-­‐supplied  keyword,  second  by   subject  terms,  and  third  by  all-­‐text,  resulting  in  nine  searches.  i  did  this  to  determine  whether  the   results  would  differ  across  each  search  specification.  i  then  cross-­‐referenced  these  lists  and     do  you  believe  in  magic?  |  zak       30   removed  duplicate  and  foreign-­‐language  results  to  compile  one  complete  data  set  of  160  articles.   recording  units  from  the  articles,  blog,  or  social  media  postings  i  collected  from  these  searches   include  explicit  assertions  concerning  ar  i  then  coded.  for  the  purposes  of  this  exploratory  study,   i  developed  codes  inductively  rather  than  approaching  the  data  with  a  predetermined  set  of  codes,   as  inductive  codes  arise  from  the  interpretation  of  the  coded  data.67  an  example  of  an  assertion  in   the  dataset  includes  the  following,  taken  from  an  article  in  my  pilot  study:     ar  is  a  very  efficient  technology  for  both  higher  education  such  as  universities  and  colleges.   students  in  both  schools  can  improve  their  knowledge  and  skills,  especially  on  complex   theories  or  mechanisms  of  systems  or  machinery.68   i  categorized  these  assertions  according  to  the  themes  or  codes  with  which  they  are  embedded.     for  instance,  in  the  assertion  above,  the  notion  that  ar  is  efficient  and  capable  of  improving  or   adding  to  knowledge  and  skills  could  be  categorized  within  similar  assertions  about  the  value  or   purpose  of  ar.  after  i  organized  the  codes  and  categories,  i  determined  which,  if  any,  of  these   codes  coincide  with  the  digital  age  principles  of  rct  interactivity,  connectivity,  and  access.   i  developed  132  codes.  a  further  reduction  of  codes  is  not  feasible  given  the  myriad  ways  ar  is   defined  across  sources  in  the  data  set,  which  underscores  the  lack  of  consensus  on  just  how  ar  is   truly  understood.  i  went  through  the  codes  and  grouped  them  according  to  similarities  and   overarching  themes  labeled  as  categories.  the  132  codes  make  up  14  categories,  listed  in  table  1.   how  is  ar  conceptualized  in  lis?   the  lista  database  includes  more  than  560  journals  from  lis  and  related  information-­‐science   fields  such  as  communication  and  museum  studies.  of  the  77  lista  sources  included  in  the  data   set  for  this  study,  46  sources  are  peer-­‐reviewed;  31  are  not.  of  those  journals  not  peer-­‐reviewed,   all  of  them  focus  specifically  on  issues  in  the  media,  technology,  education  or  libraries.  based  on   my  analysis,  the  categories  or  overarching  themes  most  prominent  in  the  lista  data  set  are  “ar   as  a  new  direction,”  “ar  as  informational,”  and  “ar  as  an  enhancement.”   taken  together,  these  categories  suggest  ar  can  deliver  information  and  the  user  can  interact  with   information  through  an  enhanced  experience,  which  is  a  new  direction  in  technology.  individually,   these  categories  are

 user  awareness  of  the  technology,  a  clear   definition  of  the  technology,  and  an  understanding  of  its  full  range  of  uses,  some  view  it  as  a  trend   that  raises  the  bar  of  technological  expectations.  when  viewed  as  a  growing  trend,  ar  is  creating  a   new  world  or  platform  for  information  delivery.   furthermore,  in  the  lista  sources  ar  is  also  viewed  as  informational.  this  category  comprises   eight  codes,  all  of  which  refer  to  the  capability  of  ar  to  deliver,  gather,  define,  present,  and   superimpose  information  rapidly.  in  this  context  for  lis,  ar  is  another  format  for  providing  the   user  with  information  tailored  to  specific  user  needs.  the  ways  ar  can  provide  users  with   information  are  nestled  in  the  view  of  ar  as  an  enhancement.   within  this  category,  ar  is  described  as  an  enhancement  of  reality,  communication,  experiences,   and  learning.  under  this  category  there  is  little  ar  will  not  enhance.  the  enhancement  of  the  user   experience  is  directly  tied  to  the  informational  quality  of  ar.  this  enhancement  rests  on  the   engaging  interactive  qualities  of  ar  fostering  relationships  and  collaboration  through  the  property   of  connectivity.  under  this  definition,  the  digital  information  ar  displays  or  “creates”  is  the   enhancement  of  the  experience.   sources  in  the  data  set  also  suggest  ar  enhances  the  learning  experience  through  the  digital   images  or  objects  presented  to  the  user  in  conjunction  with  the  “original  materials.”  the   connection  of  ar  to  the  internet  and  sources  therein  also  gives  users  the  ability  to  connect  and   collaborate  with  one  another.  the  enhanced  experiences  provided  by  way  of  ar  foster   connections  between  users  as  well  as  librarians  and  the  creators  of  ar  applications  themselves.   authors  within  the  data  set  expect  connecting  with  others  and  building  relationships  will  make   user  experiences  much  richer  in  terms  of  how  the  user  interacts  with  information  and  in  what  way   information  is  presented  to  the  user.   the  google  blogs  search  was  not  limited  to  lis-­‐specific  blogs,  as  the  search  function  is  limited  in   definable  search  parameters.  of  the  300  blog  posts  in  the  data  set,  only  four  actually  include  the   term  library  or  refer  to  ar  applications  within  libraries.  one  blog  post  alludes  to  archiving  but   does  not  explicitly  mention  a  library  setting.  these  blog  postings  code  for  versatility,  utility,   interactivity,  discovery  tool,  an  experience,  a  library  instruction  aid,  promoting  and  enhancing  the   library,  access,  and  providing  services  to  users.  while  not  all  of  these  codes  are  included  in  the  three   dominant  categories  coding  for  the  lista  sources,  they  do  reflect  the  utilitarian  quality  of  ar  as  a   provider  of  information  at  its  most  basic.  for  example,  ar  is  in  one  source  a  versatile  tool   enhancing  aspects  of  the  user’s  library  experience,  a  view  shared  with  the  aforementioned  lista   excerpts,  from  the  ways  services  are  provided  for  the  user  to  the  level  of  interactivity  the  patron   has  with  relevant  information  within  the  library,  such  as  finding  specific  book  locations  or   accessing  information  about  the  services  the  library  offers.     information  technology  and  libraries  |  december  2014   33   archiving  information  displayed  through  ar  applications  poses  a  challenge  and  is  a  necessary   consideration  for  those  interested  in  archiving  information.  truly,  ar  has  the  potential  to  change   archiving  platforms  and  access  to  those  platforms.  the  archiving  of  information  presented  via  ar   is  a  concern  for  those  implementing  ar  for  a  variety  of  purposes.  presenting  even  library  hours  or   wayfinding  information  for  a  user  through  ar  also  raises  the  question  of  how  information  will  be   accessed,  for  how  long,  and  in  what  form  it  will  exist  once  it  is  no  longer  needed,  updated,  or   changed.   the  coded  data  suggests  ar  is  conceptualized  as  a  new  development  in  digital  technology  worth   paying  attention  to,  at  least  for  now,  but  should  also  be  approached  with  some  caution;  users  or   those  looking  to  implement  ar  should  be  careful  to  understand  the  functionality  and  implications   of  using  ar  prior  to  adapting  the  technology.  as  reflected  in  the  sources,  books  and  physical   spaces  are  potential  areas  for  ar  application  and  in  some  cases  are  already  overlaid  with  ar  and   are  enhancing  user  experiences.  as  a  whole,  the  conceptualization  of  ar  is  a  technology  with  great   potential  to  change  the  way  users  interact  with  information  because  of  its  versatility,  mobility,  and   direct  interaction  with  the  user’s  immediate  environment.   what  is  the  role  of  the  user  in  relation  to  ar  as  it  is  conceptualized  in  lis?   the  user  is  the  foundation  of  ar,  giving  the  technology  its  functionality  or  prompting  action.   whether  conceptualized  as  a  new  direction,  an  information  source  or  provider,  or  an   enhancement,  ar  is  essentially  static  if  there  is  no  user  prompting  the  ar  application  to  “act.”   without  action  on  the  user’s  part,  the  information  stored  within  ar  applications  is  inert.  the  goal   of  ar  is  to  present  information  in  digital  form  within  the  context  of  the  user’s  surroundings,   environment,  or  reality.   codes  describing  ar  as  a  new  direction,  new  world,  or  new  normal  solidify  the  idea  that  ar  is  a  new   technological  development  poised  to  redefine  not  only  the  information  landscape  but  also  the   ways  users  interact  with  technology  and  information.  furthermore,  references  to  ar  as  a   seemingly  unstoppable  popular  trend  point  to  the  perceived  usefulness  and  importance  of  ar  in   the  life  of  the  user,  as  it  is  seen  to  raise  expectations  in  terms  of  how  users  access  information.  one   blog  source  writes,  “you  may  have  heard  about  augmented  reality  before.  if  you  haven’t,  you’ll  be   hearing  a  lot  about  it  from  now  on,  with  the  smartphone  and  tablet  revolution  now  in  full-­‐ swing.”69  the  “revolution”  surrounding  smartphones  and  tablets  alludes  to  the  increase  in  their   use  and  sales,  making  these  devices  staples  in  everyday  life.  this  idea  is  parallel  to  user   expectations  in  terms  of  online  resources,  as  many  users  rely  on  information  accessed  through  the   internet.70,71,72,73  the  implication  is  once  ar  applications  gain  more  widespread  use,  the  user  will   come  to  expect  access  to  a  wide  range  of  information  through  those  ar  applications.   because  ar  is  still  met  with  skepticism,  and  for  some  is  still  in  need  of  further  development,  the   technology  provides  opportunities  for  librarians  and  their  staff  as  those  implementing  and     do  you  believe  in  magic?  |  zak       34   providing  ar-­‐based  services  to  forge  new  paths  in  ar  application,  becoming  users  of  the   technology  “behind-­‐the-­‐scenes.”  the  following  excerpt  from  a  lista  source  highlights  this  view:   technological  advances  are  beginning  to  fundamentally  change  the  way  that  library  users   interact  with  digital  information,  and  it  is  therefore  essential  that  librarians  become  engaged   with  the  relevant  technology  and  leverage  their  role  as  teachers  in  order  to  help  ensure  their   continued  relevance  in  the  lives  of  clients  in  the  twenty-­‐first  century.74   within  this  statement,  librarians  are  learning  and  teaching  about  new  technology.  maintaining   “relevance  in  the  lives  of  clients”  suggests  as  the  technology  grows,  implementers  of  the   technology  need  to  understand  the  technology.  as  reflected  in  this  excerpt,  on  the  other  end  is  the   user  (or  client)  of  the  ar  application  after  it  is  created  and  implemented.  the  user  has  the   opportunity  not  only  to  access  and  experience  information  in  new  ways  but  also  to  help  build  and   contribute  to  the  creation  and  streamlining  of  the  ar  application  through  his  or  her  response  to   the  application’s  functionality.   the  user  of  ar  is  also  central  to  the  view  of  ar  as  informational.  in  a  simplistic  way,  ar  is  dormant   and  incapable  of  providing,  delivering,  searching  for,  superimposing,  or  really  doing  much  of   anything  with  information  without  user  actions.  in  most  cases  with  ar,  users  must  have  some  type   of  mobile  device  to  prompt  what  is  often  described  as  an  ar  experience.  information  provided  via   ar  applications  is  unlike  the  physical  format  of  a  book,  newspaper,  magazine,  or  other  object.   these  physical  objects  exist  in  libraries  and  the  like,  residing  on  shelves  and  taking  up  physical   space  regardless  of  the  location  or  presence  of  a  user.  by  contrast,  the  information  embedded   within  an  ar  application  is  only  viewable  and  unlocked  when  the  user  prompts  action  through  the   viewfinder  of  a  smartphone,  tablet,  or  other  mobile  device.  the  technology  is  described  as  a   catchall  or  endless  repository  for  interactive  information  for  the  user,  at  the  user’s  fingertips.   likewise,  the  conceptualization  of  ar  as  any  kind  of  enhancement  is  also  dependent  on  the  user,   though  this  assertion  is  implicit  in  many  of  the  coded  passages.  without  user  interaction   prompting  the  ar  application  to  overlay  information  onto  the  real  environment,  ar  is  incapable  of   enhancing  experiences,  libraries,  communication,  or  reality  itself.  enhancement,  or  improvement,   suggests  something  or  someone  is  acted  on  in  a  way  that  is  beneficial,  intensified,  or  embedded   with  a  stronger  sense  of  value.   much  like  the  informational  quality  of  ar,  without  the  use  of  a  mobile  device  handled  by  the  user,   ar  is  dormant  and  nonexistent,  unable  to  enhance  the  environment  or  other  aspect  of  physical  life.   without  a  user  within  a  specific  context,  there  is  not  much  for  ar  to  enhance  because  it  exists  as   merely  a  “marker,”  tucking  away  the  desired  information,  awaiting  a  user  to  come  along  and  point   a  mobile  device  in  its  direction.  as  blogger  david  meyer  put  it,  ar  “requires  the  active   participation  of  the  consumer—you  do  not  by  default  wander  around  with  your  phone  held  out  in   front  of  you.”75       information  technology  and  libraries  |  december  2014   35   this  implicit  role  of  the  user  is  buried  under  language  suggesting  ar  is  actually  capable  of  acting   on  the  user  and  the  user’s  reality,  giving  ar  a  sense  of  agency.  for  example,  in  terms  of   enhancement,  while  the  user  is  the  “activator”  of  the  ar  experience,  ar  is  often  described  as   making,  creating,  challenging,  improving,  producing,  delivering,  solving  problems,  and  even   bringing  some  object  to  life,  thus  prompting  this  “enhancement.”  such  verbs  give  ar  an  active   quality,  as  if  it  is  itself  alive  and  present  in  creating  or  prompting  change.  this  is  best  exemplified   by  the  categories  of  ar  as  acting  upon  reality,  ar  as  a  modifier  and  ar  as  conditioning  the   environment.   the  perceived  quality  of  ar  as  acting  on  reality  is  what  often  drives  the  idea  of  ar  is  a  catalyst  for   change,  conditioning  the  environment  by  either  controlling  the  present  environment  or  creating  a   new  one.  the  transformative  characteristic  of  ar  reshapes  and  redefines  the  user  experience   precisely  because  of  the  ways  ar  inserts  digital  objects  into  the  real-­‐world  environment.  for  this   reason,  ar  is  often  described  through  invoking  imagination  and  with  words  like  cool,  amazing,  fun,   and  exciting,  or  other  empty  descriptors;  ar  truly  enhances  user  interaction  with  the  surrounding   world  with  what  is  perceived  as  a  “wow”  factor,  so  much  so  that  codes  in  this  study  even  reflect   legal  and  economic  implications  of  the  technology.  but,  while  ar  is  a  catalyst  for  change  and  acts   on  the  environment  and  reality,  those  changes  and  actions  are  only  seen  through  the  viewfinder  of   a  mobile  device  ultimately  in  the  hands  of  the  user.   radical  change  theory   dresang  founded  rct  on  what  she  identified  as  the  three  digital-­‐age  principles  of  interactivity,   connectivity,  and  access,  which  describe  how  “the  digital  environment  has  influenced  some   nondigitized  media  to  take  on  digital  principles.”  essentially,  dresang’s  theory  is  an  attempt  to   explain  information  resources  and  behaviors.  within  the  digital-­‐age  principles,  the  user  takes  on   the  role  of  initiator.  while  flexible  in  allowing  user  initiation,  the  digital  applications  are  inert   without  the  user;  a  range  of  information  is  unavailable  without  user  action  to  put  the  digital   environment  into  motion.  the  digital  environment  within  ar,  as  described  by  sources  in  the  data   set,  is  an  overlay  of  the  digital  onto  the  real  world.  rct  suggests  the  “digital  environment  extends   far  beyond  the  digital  resources  themselves.”  the  extension  beyond  the  digital  resources  is  evident   in  ar  as  it  combines  the  real  and  physical  with  the  virtual.76   based  on  these  principles  and  the  idea  that  the  digital  extends  beyond  the  resources  themselves,   the  conceptualization  of  ar  reflects  the  characteristics  of  rct  in  explaining  information  behavior   and  representations  in  the  ar  “environment.”  interactivity,  connectivity,  and  access  are  essential   parts  of  ar.  when  each  principle  is  examined  in  conjunction  with  the  coded  data,  a  picture   appears  of  ar  as  an  exemplar  of  rct.   interactivity  and  connectivity  emerged  as  coded  assertions  within  the  data.  these  codes  fall  under   the  category  of  ar  as  an  enhancement.  as  stated,  ar  is  expected  by  many  of  the  voices  within  my     do  you  believe  in  magic?  |  zak       36   data  set  to  influence  or  enhance  almost  every  aspect  of  our  lives,  and  part  of  this  enhancement  is   due  to  the  properties  of  interactivity  and  connectivity  exhibited  by  ar.     as  defined  by  dresang,  interactivity  refers  to  dynamic,  user-­‐controlled,  nonlinear,  nonsequential   information  behavior  and  representation.77  speaking  directly  to  the  idea  of  user-­‐controlled,   nonlinear,  and  nonsequential  information  behavior  and  representation  is  the  sense  of  agency  that   ar  is  expected  to  give  users  in  terms  of  how  they  view  and  interact  with  the  digital  overlays  of   information.   the  control  the  user  has  on  the  ar  experience  and  the  information  with  which  he  or  she  comes  in   contact  stems  from  the  functionality  of  ar  often  relying  on  tracking  a  user’s  location.  presenting  a   user  with  information  based  on  location  is  not  only  user-­‐controlled  but  nonlinear  and   nonsequential,  since  the  application  has  no  predetermined  set  of  boundaries  the  way  a  physical   map  might  have.  people  do  not  typically  travel  through  the  day  in  a  linear  fashion  with  a   predetermined  sequence  of  action.  as  one  blogger  notes,  ar  is  “helping  to  erase  that  line  between   your  real  life  and  how  you  interact  with  the  web.”  78   ar  is  further  tied  to  the  principle  of  interactivity  as  defined  within  rct  precisely  because  of  its   mobility  and  formatting,  namely,  because  of  mobile  devices.  a  source  within  the  lista  data  set   includes  the  following  assertion:     the  ar  paradigm  opens  innovative  interaction  facilities  to  users:  human  natural     familiarity  with  the  physical  environment  and  physical  objects  defines  the  basic     principles  for  exchanging  data  between  the  virtual  and  the  real  world,  thus  allowing     gestures,  body  language,  movement,  gaze  and  physical  awareness  to  trigger  events  in  the     ar  space.79     gestures,  body  language,  movement,  gaze,  and  physical  awareness  are  all  unpredictable  actions.   for  these  actions  to  “trigger  events  in  the  ar  space,”  there  must  certainly  be  a  high  degree  of   nonlinear  and  nonsequential  information  behavior  and  representations  taking  place;  it  is  highly   unlikely  user  gestures  and  the  like  could  exist  on  a  linear  continuum  of  action.   further,  within  rct,  connectivity  refers  to  the  sense  of  community  or  construction  of  social   worlds  emerging  from  changing  perspectives  and  expanded  associations  in  the  world  and  in   resources.  in  terms  of  the  coded  data  in  this  study,  the  code  of  connectivity  reflects  this  idea  of   creating  community  and  social  worlds  through  the  capability  of  ar  to  connect  users  to  various   forms  of  social  media,  to  one  another,  and  to  various  resources.  users  make  connections  through   games,  location  awareness,  and  applications  allowing  for  the  sharing  of  information  from  user  to   user.  social  networking  figures  prominently  in  ar  technology.  users  can  upload  overlays  of  digital   information  captured  on  a  smartphone  to  various  social  networking  sites.  additionally,  the  ability   of  ar  to  overlay  digital  information  onto  the  real  world,  and  the  customizable  experiences  this   creates,  aids  in  connectivity.  ar  creates  a  virtual  world  wherein  users  can  engage  with  one   another  across  applications;  while  physically  in  different  places,  they  can  share  experiences  or     information  technology  and  libraries  |  december  2014   37   even  simple  conversations.  connectivity  through  ar  is  possible  in  all  aspects  of  life  as  many   sources  in  the  data  set  allude  to  working,  playing,  and  learning.   to  interact  and  connect  with  one  another,  users  must  have  access  to  the  ar  space.  the  principle  of   access  within  rct  is  defined  as  the  breaking  of  long-­‐standing  information  barriers,  allowing   exposure  and  access  to  a  wide  range  of  differing  perspectives  and  opportunities.  the  concept  of   access  (both  in  terms  of  what  is  and  is  not  accessible)  does  appear  in  the  coded  data.  note  access   and  accessibility  within  this  study  refer  to  the  opportunity  or  right  to  use  a  system  or  service,  and   is  not  referring  to  access  and  accessibility  as  it  is  used  within  discourse  pertaining  to  disabilities.   the  use  of  ar  in  conjunction  with  smartphones  is  a  basic  way  of  interpreting  access  as  it  relates  to   rct  and  ar.  the  mobility  of  smartphones  and  tablets  allows  users  to  access  ar  across  a  variety  of   locations,  and  each  user’s  smartphone  or  tablet  is  uniquely  tailored  to  the  user’s  interests  and   desires  through  differing  collections  of  applications  and  software.  smartphones  and  tablets  are   comparatively  low-­‐cost  options  for  accessing  and  sharing  access  to  the  internet  and  ar   applications.  their  use  is  on  the  rise  because  they  are  often  much  cheaper  to  obtain  than   computers.80,81,82  the  fusion  of  ar  with  mobile  devices  suggests  an  opportunity  for  accessing   information  in  real  time  in  any  place  through  these  technologies  working  in  tandem  with  one   another.  by  its  very  nature,  ar  offers  access  to  “differing  perspectives  and  opportunities”  as  it   presents  the  user  with  information  in  atypical  formats  in  places  and  spaces  once  static,  or  lacking   in  digital  overlays.   ar  is  not  bounded  by  physical  location;  rather,  it  depends  on  and  varies  with  your  physical   location.  the  idea  that  users  can  access  ar  wherever  there  is  an  internet  connection  means  the   only  real  barrier  to  accessing  ar  is  the  same  barrier  existing  regarding  a  web  connection  for  the   user,  something  at  least  one  source  within  the  lista  data  set  alludes  to  in  terms  of  the  digital   divide,  cautioning  that  ar  should  be  used  in  conjunction  with  traditional  formats  of  information   instead  of  in  lieu  of  them.  for  example,  libraries  should  not  replace  traditional  signage  with   information  only  embedded  within  ar  applications.  however,  as  more  and  more  organizations,   institutions,  and  businesses  use  ar  and  provide  users  with  access  rather  than  relying  on  the  user   to  conjure  his  or  her  own  internet  connection,  more  barriers  to  ar  will  fall.     however,  it  is  important  to  note  that  not  all  ar  applications  actually  do  require  internet  access.   mobile  device  applications  can  work  off  of  markers  and  triggers  in  the  physical  environment,  not   web-­‐based  anchors.  for  example,  a  cookbook  can  include  a  marker  next  to  a  recipe  that  when   scanned  displays  an  image  of  the  finished  dish.  access  to  ar  applications  without  a  web   connection  opens  a  wealth  of  information  to  individuals  who  do  not  have  access  to  the  web.  not  all   ar  applications  link  to  web-­‐based  information,  and  this  widens  the  pool  of  users  engaging  with   information  through  those  ar  applications.  moreover,  relative  ease  of  use  and  low  initial  cost  to   create  ar  applications  also  allow  users  to  become  content  creators,  as  exemplified  by  an  ar   application  allowing  an  artist  to  create  virtual  graffiti  in  public  spaces.  users  are  able  to  display   and  access  information  otherwise  invisible.     do  you  believe  in  magic?  |  zak       38   it  is  important  to  note  the  differing  views  suggesting  ar  does  and  does  not  require  internet  access   to  function.  such  a  discrepancy  points  further  to  ar  as  a  loosely  defined  concept.  from  a  technical   standpoint,  ar  does  not  require  an  internet  connection,  but  the  internet  does  serve  as  a   repository  for  information,  and  many  see  ar  as  providing  a  bridge  to  that  information,  be  it  a   company  wanting  to  give  consumers  access  to  product  lines  or  a  library  creating  an  ar  application   linking  to  web-­‐based  databases  and  services.  in  terms  of  rct,  the  principle  of  access  does  take   into  account  digital  information  as  able  to  both  provide  and  inhibit  access,  as  some  users  may  not   have  access  to  the  often  costly  hardware  allowing  access  to  digitally  formatted  information.  what   is  important  to  highlight  about  the  principle  of  access  is  the  focus  on  the  range  of  voices  and  the   increased  array  of  digital  information  available,  which,  in  the  case  of  this  study,  ar  provides.  any   object  associated  in  some  way  with  a  monetary  cost  or  technical  savvy  always  has  the  potential  to   leave  some  users  in  the  dark.   interactivity,  connectivity,  and  access  are  present  in  the  conceptualization  of  ar  within  the  lis   literature  as  well  as  the  popular  media  blogs.  the  user  is  central  to  both  rct  and  this   conceptualization  of  ar  as  a  new  technology  with  the  potential  to  change  the  way  users  interact   with  information  and  with  one  another.  the  goal  of  ar  is  to  present  information  in  digital  form   within  the  context  of  the  user’s  surroundings,  environment,  or  reality.  rct  is  a  theory  seeking  to   understand  changes  in  information  behavior  and  representations,  and  ar  is  an  exemplar  of  the   myriad  changes,  or  the  evolution,  of  the  digital-­‐information  environment.   implications  for  theory   this  study  has  several  implications  for  theory  within  lis.  these  include  the  extension  of  rct  or   creation  of  new  theories  born  out  of  the  digital  age,  the  understanding  that  a  user-­‐centric  focus  is   essential  to  theory  within  the  digital  age,  and  the  realization  that  ar  opens  new  areas  of  research   in  what  is  considered  an  enhancement  of  information.  while  this  study  sought  to  test  rct  in   relation  to  the  conceptualization  of  ar,  it  also  provides  a  framework  for  future  studies.  the  results   of  this  study  also  suggest  ar  opens  more  areas  to  explore  within  the  field  of  lis  to  create  new   theories  or  to  add  to  rct  as  a  theoretical  framework  to  better  understand  information  behavior   and  representations  in  the  digital-­‐information  environment.   when  dresang  initially  formulated  rct,  she  focused  on  youth  information  seeking  behaviors.83   few  scholars  have  used  the  theory,  but  those  that  have  explore  education,84  literacy,85     communication  and  writing86  as  related  to  changing  technologies.  these  previous  studies,  as  well   as  this  study,  highlight  the  importance  of  this  theory  in  examining  the  effect  of  the  digital-­‐ information  landscape  on  information-­‐seeking  and  user  understanding  of  and  reaction  to  digital   information.  rct  is  viable  beyond  a  focus  on  youth  information  seeking  and  is  highly  relevant  to   today’s  world.     rct  developed  to  understand  how  the  digital  age  influences  traditional  and  new  media.  ar  is  itself   often  described  as  an  environment,  a  digital  environment,  which  is  precisely  the  focus  of  rct.  if     information  technology  and  libraries  |  december  2014   39   ar  is  in  fact  a  “new  normal,”  as  some  describe,  our  information  landscape  is  moving  in  a  direction   where  interactivity,  connectivity,  access,  and  the  role  of  the  user  are  central  to  any  discussion  of   how  information  is  organized,  distributed,  formatted,  and  presented.   researchers  can  begin  by  adapting  traditional  lis  theories  to  the  digital  age.  for  example,  wilson   revised  his  oft-­‐cited  original  general  model  of  information-­‐seeking  behavior  in  an  attempt  to   understand  the  totality  of  information  behavior  by  linking  theory  to  action  and  understanding   what  prompts  and  hinders  the  need  to  search  for  information.87  researchers  can  begin  to   reevaluate  the  model  to  determine  whether  it  helps  to  explain  information  behavior  within  the  ar   environment,or  whether  aspects  of  the  model  can  be  further  developed  or  revised.  wilson’s   model’s  focus  on  human  behavior  parallels  the  focus  on  human  behavior  within  the  ar   environment.   other  theories  within  lis  can  also  be  adapted  to  the  ar  environment,  such  as  erdelez’s   information  encountering  (ie).  erdelez’s  theory  focuses  on  a  “memorable  experience  of   unexpected  discovery  of  useful  or  interesting  information”  situated  within  three  elements:   characteristics  of  the  information  user,  characteristics  of  the  information  environment,  and   characteristics  of  the  encountered  information.  erdelez  further  describes  categories  of   information  users:  superencounterers,  encounterers,  occasional  encounterers,  and   nonencounterers.  while  erdelez  has  since  taken  the  web  and  the  internet  into  account  as   information  environments,  this  theory  could  further  be  remodeled  to  include  the  ar   environment.88   wilson’s  model  and  erdelez’s  theory  are  just  two  examples  of  theories  within  lis  lending   themselves  to  further  exploration  of  the  user  of  ar  within  lis.  bates’  model  of  information  search   and  retrieval,  known  as  berrypicking,  which  centers  on  the  changing  nature  of  the  search  query   through  the  search  process,  can  also  be  amended  to  include  information  search  and  retrieval   within  the  ar  environment.89  bates’  model  suggests  as  users  seek  and  find  information,  the   information  search  shifts  from  source  to  source.  the  berrypicking  model  can  also  be  updated  or   expounded  in  response  to  ar  because  of  ar’s  multidimensional  display  of  information—a   relatively  new  phenomenon  for  the  average  user—to  understand  whether  the  same  shift  in   information  queries  occurs  and  what  new  paths  to  information  users  are  taking  within  the  ar   environment.   this  study  suggests  a  user-­‐centric  focus  is  essential  to  any  theories  in  lis  developed  within  or   extended  to  the  digital  age.  the  user  is  vital  to  making  ar  technology  functional,  as  demonstrated   in  the  conceptualization  of  ar  in  this  study.  the  personalization,  individualization,  and  mobility  of   digital  technology  like  ar  suggest  theories  related  to  information  behavior  within  this   environment  must  account  for  user  interaction.  information  is  no  longer  contained  within  static   formats.  geotagging  or  geospatial  awareness  and  social  networking  are  prime  examples  of  the   reliance  of  digital  technology  on  user  interaction.  without  addressing  the  role  of  the  user  in  the     do  you  believe  in  magic?  |  zak       40   functionality  of  digital  technology  in  any  context,  theoretical  frameworks  attempting  to  address   information  seeking  and  behavior  in  the  digital  age  will  be  limited.   additionally,  should  ar  prove  to  be  a  new  direction  in  accessing,  organizing,  delivering,  and   obtaining  information,  it  further  opens  new  areas  of  theoretical  research.  since  ar  is  considered   an  enhancement  of  the  information  experience,  it  is  incumbent  on  researchers  to  determine  just   how  “enhancement”  is  defined  in  the  context  of  ar  and  how  that  translates  to  the  user  experience.   researchers  can  strive  to  apply  and  understand  the  concept  of  an  enhancement  in  relation  not   only  to  the  enhancement  of  information  but  also  to  the  experience  of  accessing,  organizing,   delivering,  and  obtaining  information.  the  digital-­‐age  principles  outlined  by  dresang  in  rct  are   just  one  example  of  how  to  understand  the  impact  of  the  digital  age  on  the  user’s  interaction  with   information  and  in  what  ways  the  digital  age  creates  enhancements.   by  itself,  the  study  of  ar  technology  raises  more  questions  than  it  answers.  the  study  of  ar   technology  could  lead  to  more  diverse  theoretical  frameworks  seeking  to  answer  not  only   practical  questions  but  also  those  more  philosophical  in  nature,  working  toward  an  understanding   of  how  the  digital-­‐information  environment  influences  everyday  life  as  it  evolves  and  changes  at  a   rapid  pace.   implications  for  practice   this  study  can  inform  several  aspects  of  practice.  i  expound  on  three  possibilities:  the  clear   definition  of  technologies  like  ar  to  create  an  awareness  and  understanding  of  those  technologies,   development  of  best  practices,  and  the  need  for  a  focus  on  user  collaboration  in  the  design  and   functionality  of  ar  and  similar  technologies.  the  implications  for  practice  concern  both  the  user   and  the  provider  of  information  services.   this  study  provides  perspective,  or  a  starting  point,  from  which  the  field  of  lis  can  begin  to   analyze  the  use  and  implementation  of  ar  technology.  by  taking  a  step  back  to  understand  the   current  conceptualization  of  ar,  practitioners  within  lis  can  begin  to  seek  consensus,  identify   best  practices,  maintain  an  awareness  of  how  the  technology  is  used  and  think  realistically  about   what  factors  contribute  to  successful  implementation  of  the  technology  in  a  given  institution.  as   identified  in  the  study,  ar  is  seen  as  a  new  direction.  it  is  important  for  those  within  the  field  to   understand  this  perspective  and  to  go  on  to  identify  what  a  new  direction  in  information  gathering,   organization,  and  seeking  implies  for  the  field  as  a  whole  and  for  users.   as  a  field,  lis  can  begin  to  have  a  broader  discussion  on  what  exactly  ar  can  provide  and  how  it   can  benefit  user  services.  such  a  discussion  can  help  practitioners  make  sense  of  how  this   technology  can  work  with  traditional  sources  of  information.  ar  can  be  integrated  with  the   traditional  rather  than  act  as  a  replacement  for  the  traditional.  this  broader  discussion  can  lead  to   a  consensus  on  how  best  to  define  ar  as  a  tool  and  concept.  within  this  study,  it  is  evident  ar  is   described  in  myriad  ways,  so  it  is  important  to  reflect  on  those  descriptions,  understand  what  the   issues  are  surrounding  the  technology,  and  collaboratively  seek  and  identify  best  practices.     information  technology  and  libraries  |  december  2014   41   furthermore,  by  identifying  best  practices,  practitioners  can  begin  to  pinpoint  what  applications   of  ar  are  successful  within  an  institution  and  for  users,  and  why  those  applications  are  successful   for  specific  purposes.  in  doing  so,  practitioners  can  build  ar  applications  around  the  needs  and   mission  of  the  institution  rather  than  simply  flock  to  use  a  new  technology.  it  is  therefore  critical   for  practitioners  to  think  realistically  about  ar  implementation.  adopting  such  a  technology  will   only  be  beneficial  once  practitioners  in  the  library  understand  its  full  impact.  experience  with   technology  and  programming,  knowledge  of  ar  functionality,  versatility,  and  cost  are  important   factors  to  consider  when  contemplating  how  an  institution  can  benefit  from  ar,  if  at  all.   similarly,  publishers  are  using  ar  to  supplement  traditional  printed  books.  educators  are  using   ar  books  in  the  classroom  and  supplementing  traditional  course  instruction  with  these  books.   such  books  allow  for  3d  rendering  of  models  for  study,  such  as  planets,  molecular  structures,  and   various  other  objects.  those  within  lis  have  a  strong  connection  to  the  field  of  education,  and  ar   books  may  become  a  part  of  the  library  collection  as  they  become  more  popular  among  educators.   practitioners  in  lis  through  collaboration  with  educators  will  then  need  to  be  aware  of  these   books,  their  functionality,  and  how  to  help  users  access  the  content  lying  dormant  until  “activated”   by  a  smartphone  or  tablet.  this  raises  the  question  as  to  whether  smartphones,  tablets  or  other   devices  that  can  scan  the  environment  will  become  commonplace  in  the  library  to  provide  full   access  to  users.     user  collaboration  also  becomes  central  to  understanding  the  implications  of  ar  on  practice.  user   collaboration  in  design  is  important  because  ar  technology  is  largely  dependent  on  user  context.   as  the  data  suggests,  ar  is  considered  an  enhancement—of  the  environment,  of  information,  and   of  the  user  experience.  prior  to  implementation,  it  is  critical  to  understand  how  ar  enhances  the   user  experience  and  what  the  perception  is  among  users.  user  surveys  can  lead  to  tailored  ar   applications  for  a  given  library  or  cultural  institution  community  should  there  be  a  need  or  desire   for  ar  applications  identified  among  users.  coupled  with  the  idea  of  user  collaboration  in  design  is   also  the  need  to  reevaluate  the  physical  spaces  of  libraries  and  similar  institutions.  because  ar   creates  an  overlay  of  digital  information  on  the  physical  environment,  it  will  be  necessary  for   practitioners  to  identify  what  areas  of  the  library  or  institution  lend  themselves  to  digital  overlays,   what  types  of  information  users  are  accessing  through  ar  applications,  and  whether  the  library   space  is  configured  to  allow  for  navigating  space  via  ar.   practitioners  can  also  begin  to  survey  the  role  of  rct  in  understanding  user  information-­‐seeking   behavior.  by  acknowledging  this  theory  as  an  outline  of  our  digital-­‐information  environment,   practitioners  can  be  mindful  of  user  expectations  and  behaviors  as  they  differ  from  traditional   information  representations  and  methods  of  information  retrieval.  as  ar  creates  an  environment   or  experience  for  the  user,  it  is  important  for  practitioners  within  the  field  to  understand  how  this   technology  is  moving  forward  and  what  effect  it  has  on  the  sea  change  occurring  in  user   acquisition  of  information.  rct  is  a  framework  providing  practitioners  the  lens  through  which  to   make  sense  of  the  sea  change  and  predict  what  might  be  on  the  horizon.     do  you  believe  in  magic?  |  zak       42   limitations  and  future  application   this  study  is  just  one  step  in  the  process  of  understanding  how  new  technology  is  conceptualized   and  what  effect  that  conceptualization  has  on  implementation.  should  ar  continue  to  grow  in   popularity,  this  study  can  serve  as  a  model  for  future  research  seeking  to  understand  concepts   misinterpreted,  misunderstood,  or  undergoing  concrete  development.  utilizing  the  explicit   assertion  as  a  unit  of  analysis  coupled  with  rct  can  aid  in  investigations  of  other  digital   technologies,  both  in  terms  of  implementation  and  end  use.     the  data  set  and  the  time  period  during  which  the  searches  of  the  data  set  took  place  in  this  study   highlight  two  of  the  study’s  limitations.  further  studies  can  focus  on  a  wider  range  of  sources  not   limited  to  one  database  or  blog  search  type  and  extend  over  a  longer  period  of  time.  these   limitations  have  potentially  excluded  other  voices,  perspectives,  and  definitions  of  ar,  and  the   time  element  may  exclude  new  applications  or  uses  of  ar  currently  being  implemented.     limitations  in  data  analysis  also  exist.  content  analysis  is  one  of  many  research  methods   researchers  can  employ  to  explore  this  topic.  ethnographic  research  and  user  interviews  can  lead   to  a  deeper  understanding  of  how  users  perceive  ar  and  information-­‐seeking  or  behavior  within   the  ar  environment.  such  qualitative  studies  can  provide  insight  to  the  role  of  the  user  lacking  in   this  study.  moreover,  this  researcher’s  own  admitted  bias  against  the  steadfast  use  of  digital   technologies  prior  to  in-­‐depth  understanding  is  what  prompted  the  qualitative  inquiry  guiding  the   study.  quantitative  methods  can  also  be  used  to  track  the  popularity  or  perceptions  of  ar  through   close-­‐ended  questionnaires  or  surveys  of  both  users  and  practitioners  in  the  field  of  lis.  citation   tracking  could  further  reveal  in  what  subfields  of  lis  the  conversation  surrounding  ar  is  taking   place,  and  may  also  uncover  whether  any  one  researcher  or  group  of  researchers  is  leading  the   conversation.     future  studies  can  examine  and  expand  on  the  results  of  this  study.  rather  than  focusing  on   conceptualization  only,  researchers  can  study  which  professional  fields  dominate  the  conversation   surrounding  ar  and  what  areas  of  popular  culture  dominate  the  conversation  or  influence   understanding  of  ar.  similarly,  other  studies  can  address  the  specificity  of  each  source  making   explicit  assertions  about  this  kind  of  technology.  while  qualitative  in  nature,  the  study  is  limited   because  it  does  not  examine  quantitative  changes  in  the  number  of  articles  or  blog  posts  alluding   to  ar  over  an  extended  period  of  time.  such  studies  might  unravel  why  ar  is  progressing  as  it  is,   and  may  identify  potential  problems  or  differences  in  the  influence  of  these  perspectives  on  the   use  of  ar.   the  study  of  ar  also  widens  the  spectrum  of  user  studies.  augmented  reality  open  a  whole  new   area  of  user  interaction  with  information  extending  beyond  the  screen.  with  the  advent  of   products  like  google  glass  and  applications  overlaying  digital  information  at  the  click  of  a  button   in  an  endless  array  of  contexts  and  environments,  ar  brings  information-­‐seeking  further  into  a   world  of  instability  and  unpredictability.  the  complex  nature  of  individual  people  is  now  being   coupled  with  a  highly  individualized  complex  technology.     information  technology  and  libraries  |  december  2014   43   the  functionality  of  ar  prompts  the  need  for  archival  studies  related  to  this  technology.  the   mobile  aspect  of  ar,  the  highly  personalized  content  and  the  intangible  quality  of  the  information   stored  within  ar  applications  highlights  the  need  for  an  examination  of  how  such  information  can   actually  exist  within  an  archive  and  be  made  accessible,  or  whether  such  information  even  should   exist  within  an  archive.  such  a  question  for  those  within  lis  also  suggests  the  need  for  a  realistic   perspective  on  technology  like  ar—the  next  step,  or  reaction  to  such  technology,  is  often   unrecognizable  and  unidentifiable  until  the  concept  itself  is  dissected  and  each  part  is  interpreted   and  understood.   conclusion   in  this  study,  i  used  content  analysis  to  explore  the  conceptualization  of  ar  technology  within  the   field  of  lis.  the  model  for  this  study  is  the  work  of  clement  and  levine  and  their  use  of  the  explicit   assertion  as  a  unit  of  analysis.90  i  coded  and  examined  explicit  assertions  pertaining  to  ar  in  lis   literature  and  google  blogs  to  determine  how  the  concept  of  ar  is  understood.  analysis  shows  ar   is  most  prominently  conceptualized  as  a  new  direction  in  technology  and  media  consumption   acting  on  reality  and  as  enhancing  reality  and  interaction  with  information.   ar  is  basically  a  technology  allowing  for  digital  information  to  be  superimposed  on  the  real  world.   but  beyond  that,  it  is  a  technology  changing  the  way  users  interact  with  information,  and  it  has  the   potential  to  continue  changing  how  we  literally  see  information.  the  data  set  suggests  those   within  lis  conceptualize  ar  as  a  new  development  in  digital  technology  worth  paying  attention  to,   at  least  for  now,  but  should  also  be  approached  with  some  caution  to  be  fully  understood  prior  to   implementation  in  case  its  popularity  and  growth  is  fleeting.  as  reflected  in  the  data  set,  books  and   physical  spaces  are  potential  areas  for  ar  application,  and  in  some  cases  are  already  overlaid  with   ar  and  enhancing  user  experiences.  as  a  whole,  ar  is  conceptualized  as  a  technology  with  great   potential  to  change  the  way  users  interact  with  information  because  of  its  versatility,  mobility,  and   direct  interaction  with  the  user’s  immediate  environment.   within  this  conceptualization,  the  user  is  central  to  igniting  the  functionality  of  ar.  whether   conceptualized  as  a  new  direction,  an  information  source  or  provider,  or  an  enhancement,  ar  is   essentially  static  if  there  is  no  user  prompting  the  ar  application  to  “act.”  the  goal  of  ar  is  to   present  information  in  digital  form  within  the  context  of  the  user’s  surroundings,  environment,  or   reality.  as  a  field  dedicated  to  user  services  in  regard  to  information-­‐seeking,  it  is  imperative  to   understand  the  potential  impact  this  technology  has  had  or  will  have  on  everyday  life.   rct  is  a  theoretical  framework  aiding  in  the  exploration  of  the  potential  impact  of  ar.  born  out  of   a  desire  to  understand  the  influence  of  the  digital  age  on  the  traditional  or  “analog”  media  with   which  we  engage,  rct  is  one  of  few  theories  resting  entirely  on  the  characteristics  driving  our   digital-­‐information  environment,  outlined  specifically  as  interactivity,  connectivity,  and  access.   utilizing  this  theory  as  a  lens  for  future  research  regarding  digital  information  is  a  natural  next   step  in  theory  exploration  and  development.     do  you  believe  in  magic?  |  zak       44   together,  ar  and  rct  accentuate  the  evolution  of  how  we  consume  and  display  information.  from   storytelling  to  printed  pages  to  electronic  devices,  our  engagement  with  information  will  never  be   the  same  again.  as  we  move  forward,  it  is  important  to  continue  to  ask  new  questions,  seek  new   explanations,  and  try  to  formulate  the  most  appropriate  answers  for  the  contexts  in  which  we  all   deal  with  information,  be  it  gathering,  organizing,  seeking,  or  understanding.  this  study  is  one   piece  in  a  puzzle,  and  it  prompts  more  questions  than  it  provides  answers.  ar  can  and  should  be   studied  from  every  aspect  of  the  field  of  lis,  if  it  is  in  fact  a  new  direction  toward  our  new  normal.   references     1.     nathan  crilly,  “the  design  stance  in  user-­‐system  interaction,”  design  issues  27,  no.

wooseob jeong a prototype of a touchable online braille generator has been developed for the visually impaired or blind using force feedback technology, which has been used in video games for years. without expensive devices, this prototype allows blind people to access information on the web by touching output braille displays with a force feedback mouse. the data collected from user studies conducted with blind participants has provided valuable information about the optimal conditions for the use of the prototype. the end product of this research will enable visually impaired people to enjoy information on the web more freely. the united states has made some attempts to nationally address information access for those with disabilities. section 508 of the rehabilitation act (www.section508.gov) requires federal agencies to make their electronic information accessible to people with disabilities, mainly those who are visually impaired. the library of congress launched a webbraille service (www.loc.gov/nls/) for the blind in 1998, which continues today. with the upsurge in information stored on the internet, the importance of these issues cannot be overemphasized. many products have been developed to help the visually impaired use technology. several braille output and input devices are available, such as the braille notetaker (www. artictech.com) and voice synthesizers for screen readers like jaws (www. freedomscientific.com/fs_products/ software_jaws.asp). while these products are mainly for textual information, recent developments put more focus on graphical displays. the american national institute of standards and technology proposed a “pins” down imaging system for the blind (www.nist.gov/ public_affairs/factsheet/visualdisplay.htm). uniplan in japan and ksg america (www.kgs-america.com/ dvs.htm) have produced other products based on similar ideas. software like the duxbury braille translator (www.duxburysystems.com) can translate plain text into braille output, which can then be used for embossed printing. however, such products are fairly expensive, ranging from hundreds to several thousands of dollars in addition to the cost of computers. fortunately, there is a potentially promising solution. based on the technology used in prior research, it is possible to develop an online braille generator.1 the braille could then be read either by touching the screen with a fingertip sensor or through the use of a force feedback mouse similar to the type used in some video games.2 this application has several advantages over existing devices. first, it does not require expensive special devices—only a $20 mouse, which is readily available. also, the technology is available as long as there is access to the internet. another advantage is that this technology utilizes the existing braille skills of visually impaired people. the same technology can be used for producing image displays as well, allowing for the creation of a virtual museum for the blind where they can touch objects that are displayed alongside their braille descriptions. literature review force feedback has been studied under the name of haptic perception. haptic perception involves sensing the movement and position of joints, limbs, and fingers through kinesthesia and proprioception, and sensing information through the skin’s tactility.3 haptic output can be achieved through several techniques, including pneumatic, vibrotactile, electrotactile, and electromechanical stimulation.4 this study examines only vibrotactile haptic output methods because vibrotactile stimulation is easily created, manipulated, and delivered. it is also easily perceived by users through the use of commonly available software and devices. researchers have begun to develop various haptic input/output devices and software, such as massachusetts institute of technology’s (mit) frequently used phantom haptic interface.5 along with these developments, a number of studies have tried to apply haptic displays to real-world computing, including a force feedback braille system,6 force feedback virtual reality modeling language (vrml),7 a force feedback x window system8, and gis.9 haptic studies have only recently become more mainstream, and there are few extensive studies with real subjects. gillespie and others developed the “virtual teacher,” a device for manual skill learning, which they tested with 24 participants and found that most profited from the “force feedback teacher.” 10 langrana and others used the rutgers master ii, a dexterous, portable master for virtual reality simulations for force feedback using four fingers. in their experiment of tumor detection in virtual livers with 32 subjects, the experimental group with force feedback training performed slightly better than the control group.11 this may mean that either the training methods need improvement or that the task did not require extensive training. colwell and others confirmed that a haptic interface (impulse engine 3000) has considerable potential for blind computer users through their threedimensional objects experiment with 22 subjects.12

online braille generator | jeong 49 tasks in auditory and haptic displays with 23 subjects and found that subjects performed better with haptic-only displays than with auditory-only displays or with auditory/ haptic combination displays.13 several studies already attempted to apply force feedback technology to assist blind people’s computing. ramstein conducted a pilot study to apply haptics to braille.14 yu and brewster compared the use of force feedback in multimodal virtual reality and printed medium in visualization for the blind.15 tzovaras and others tried to implement a virtual reality interface with force feedback for blind people.16 ramloll and others studied the use of haptic line graphs with sound for blind students.17 emery and others tested a multimodal haptic interface with 29 older adults to find that all participants performed well under auditory-haptic bimodal feedback.18 jacko and others tested a multimodal interface with 29 normal vision older adults and 30 visually impaired older adults, finding that in some cases, nonvisual feedback forms—including auditory or haptic feedback—demonstrated significant performance gains over the visual feedback form.19 s. jeong and others proposed an interactive system that combines an immersive virtual environment with a humanscale haptic interface.20 when conducting user studies with the visually impaired, it is necessary to separate the completely blind from the partially sighted. in spite of the different characteristics of these two groups, the literature on visually impaired people typically does not distinguish between them. this distinction is especially important if the legally blind or those with low vision are included in the definition of visually impaired. the challenges to the partially sighted are different from those of the totally blind, demanding different assistance and considerations. in fact, the completely blind represent a small portion of the visually impaired population. according to an advisor in wisconsin’s division of vocational rehabilitation, less than 5 percent of her advisees are totally blind and require very specialized attention quite different from partially sighted people. purpose of study the purpose of this study is to explore the feasibility of using force feedback technology to facilitate blind people’s access to text information on the web. both quantitative and qualitative data were collected to identify the optimal conditions under which the prototype can best serve the blind. significance of study public libraries in the u.s., primarily through their main libraries, are providing special services for the visually impaired. currently, the core service is the provision of audiobooks. as digital libraries prevail, services for the blind should be online as well, with the the library of congress’s web-braille service as one of the leading examples. however, such services require the use of an expensive braille output device. upon refinement, this prototype would significantly improve the experience of the visually impaired using online services. this prototype can be easily expanded to support graphical displays without any additional devices, making the use of touchable picture books possible for blind users in libraries. prototype development force feedback technology has been used for many years in video games. its use has expanded to other areas such as surgical operations and dangerous mechanical processes. this technology was previously applied to gis to solve the problem of ambiguous multicolor displays for multi-variable thematic maps.21 the same technique was used for this project. the online braille generator translates text on the web into a braille display, letting the user feel the braille dots with a vibrating mouse. the prototype interface was developed using immersion studio (www.immersion.com), javascript, perl/cgi, and active server pages (asp). logitech’s ifeel mouse, inexpensive at a cost of $20, was used for force feedback output (figure 1). the interface has an input text box, which can be filled with any plain text. once it is submitted, the text is instantly translated into braille (figures 2 and 3). when the user moves the mouse over each dot on the screen, it vibrates with a given force. while users explore the screen with the vibrating mouse, force feedback dots provide a tactile effect similar to braille displays. in future projects, the manual configure 1. experimental setting 50 information technology and libraries | march 200850 information technology and libraries | march 2008 version programs will be upgraded to automatic conversion programs with which any texts on the web can be grabbed by their urls and converted into a touchable format for the blind. participants to make this prototype more usable, user studies were conducted in milwaukee, wisconsin, with 21 participants who are completely blind and read braille. the small sample size—due to the relatively small percentage of visually impaired people who are completely blind and can read braille—is comparable to or larger than those found in other research on the blind. the participants came from various age groups—teens (3), twenties (6), thirties (2), fifties (5), and sixties (5)—and included 9 females and 12 males. nineteen of the 21 were born blind. participants were recruited at several sites, including the university of wisconsin–milwaukee student accessibility center, public libraries with centers for the blind, and nonprofit organizations for the physically impaired. vision teachers in local school districts were also contacted. participants provided valuable i n f o r m a t i o n about the optimal conditions for the use of the prototype. this information will eventually lead to force feedback displays that enable visually impaired people to access the vast amount of information on the web without expensive devices. experimental procedure experiments were conducted in a number of settings, including in the organization’s offices, at the participants’ homes, and at the site of a regional annual meeting for the blind. each session lasted no more than 60 minutes. participants were asked to try different interfaces of force feedback braille outputs with various dot sizes and magnitudes of force. they used a tactile mouse on a notebook computer; after exploring every option, they were asked to select the most comfortable settings for their sense of touch, including what size the dots should be, how strong the force should be, what kind of force feedback should be used (vibration or friction), and their general opinions of the prototype (see figure 4). interviews accompanied the experiments so that both quantitative and qualitative data could be collected. interviews were transcribed for qualitative data analysis. result even though there were only 21 study participants, a number of issues were clearly identified. it is encouraging to see that all of the participants could identify braille characters using the force feedback mouse with the guidance of the researcher. all the participants agreed that this prototype would be useful with training. the participants preferred the largest dot size (30 pixels in diamfigure 2. touchable braille input screen figure 3. touchable braille output screen figure 4. inexpensive force feedback mouse article title | author 51touchable online braille generator | jeong 51 eter) and the strongest force possible for maximum perception of the force feedback effect. however, the prototype was less attractive to the participants than the currently dominant voice synthesizer software. at least two participants mentioned that their current braille pads fulfill their needs. it seems that they are not motivated to invest their time and effort in a new device. when a potential graphical display application was introduced at the end of a session, the participants became more receptive. at this time there is no practical solution for the visually impaired to feel graphics on computers. experimental devices are available, but they are either quite expensive or still in the research phase. the blind participants also suggested that this graphical prototype could be used for geometry and geography easily and effectively. discussion blind people’s navigation by mouse because blind people do not use a mouse for computing, using the force feedback mouse itself was a challenge for the study participants. a sighted person uses a mouse with both hand and eye, moving the mouse while watching the mouse cursor on the screen. for the blind it is difficult to identify the mouse’s position. the direction of movement and the distance between two points are difficult to grasp. due to the lack of guidance, the blind encounter difficulties in moving the mouse in a straight line. these issues hinder the effectiveness of force feedback displays for the blind. however, this issue does not only affect the blind. some sighted people, especially older adults, cannot move a mouse easily. one possible solution may be to develop guardrails to help blind people to differentiate relevant areas of the screen from irrelevant ones. due to their inexperience in using a mouse, the participants held the mouse too firmly to move it or to feel the force feedback. the only participant to use the mouse successfully was a college student who is music major with 15 years of piano playing experience. this implies that a significant learning session will be required to allow blind people to use the mouse freely. ignorance or suppression of graphical information need even though the participants were more excited about the potential graphical displays, blind people’s graphical information needs are limited. it is possible that their graphical information needs are ignored or suppressed based on their lifetime experiences. they tend to resort to braille and, more recently, voice synthesizers instead of graphical displays. this finding suggests the importance of studying the real information needs of the blind or visually impaired rather than the sighted researchers’ expectations of those needs. more research needed with sound because the blind already use sound, particularly voice synthesizers, more sound applications should be researched. for example, audio games have the potential to help blind children learn some skills in the same way that video games teach certain skills to sighted children. audio games also provide a broader research area for future studies. conclusion numerous devices have been developed to improve blind or visually impaired people’s access to information, including information on the internet. however, such devices are quite expensive or limited in flexibility and mainly work in text-only environments. there is no suitable graphic display for the blind, except the laboratory level’s expensive and bulky pin-based external devices. this new prototype uses established force feedback technology with a minimal cost to existing pcs. it functions for both text and graphics. the final products derived from this study can be used for many purposes nationally and internationally. information on the web can be delivered to the visually impaired without expensive devices. this touchable braille also lets deaf-blind people, who cannot use screen reader software, access information on the web, and it can help people learn braille. the application of this force feedback prototype to image displays has exciting and enormous potential because currently there is no practical, usable method for the blind to access images. for example, blind children are still using handmade 3-d picture books that are labor-intensive and time-consuming to produce. with this prototype, children’s books can be delivered easily to blind children, who will touch the books’ images via the force feedback mouse. maps of local, state, national, or international interests can be delivered to the blind as well. this prototype will help to add yet another sense—touch—to already blossoming visual and auditory digital libraries. through force feedback technology, new multimodal digital libraries will be accessible to the world. acknowledgement this research was supported by a

information technology and libraries | september 2007 w elcome to my first ital president’s column. each president only gets a year to do these col­ umns, so expectations must be low all around. my hope is to stimulate some thinking and conversation that results in lita members’ ideas being exchanged and to create real opportunities to implement those ideas. my first column i thought i would keep short and sweet, and discuss just a few of the ideas that have been rattling around in my head since the 2007 midwinter lita town meeting, which have been enhanced by a number of discussions among librarians over the last six months. with any luck, these thoughts might have some bearing on what any of those ideas could mean to our organization. first off, i don’t think i can express how weird this whole presidential appellation is to me. i am extremely proud to be associated with lita, and honored and surprised at being elected. i come from a consortia envi­ ronment and an extremely flat organization. solving problems is often a matter of throwing all the parties in a room together and hashing it out until solutions are arrived at. i’ve been a training librarian for quite a while now, and pragmatic approaches to problem solving are my central focus. i’m a consortia wrangler, a trainer, and a technology pusher, and i hope my approach is, and will be, to listen hard and then see what can be accomplished. so in my own way, i find being president kind of on the embarrassing side. it’s like not knowing what to do with your hands when you’re speaking in public. at the lita town meeting (http://litablog .org/2007/06/17/lita­town­meeting­2007­report/) it was pretty obvious that members want community in all its various forms, face­to­face in multiple venues and online in multiple venues. it’s also pretty obvious from the studies done by pew internet and american life and by oclc that our users, and in particular our younger users, really want community. the web 2.0 and the library 2.0 movements are responses to that desire. as a somewhat flippant observation, we spent a generation educating our kids to work in groups, and now we shouldn’t be sur­ prised that they want to work and play in groups. many of us work effectively in collaborative groups everyday. we find it exciting, productive, and even fun. it’s an environment that we would like to create for our patrons, in­house and virtually. it’s what we would like to see in our association. having been to every single top tech trends program and listened to the lita trendsters, one theme that often comes up is that complaining about the systems our ven­ dors deliver can at times be pointless, because they sim­ ply deliver what we ask for. there is of course a corollary to this. once a system is in the marketplace, adding func­ tionality often becomes centered around the low­hang­ ing fruit. as a fictitious example, a vendor might easily add the ability to change the colors of the display to the patron, but adding a shelf list browse might take serious coding to create. so through discussions and rfp, we ask for and get the pretty colors while the browsing function waits, a form of procrastination. so then does innovation come only when all the low­hanging fruit has finally been plucked, and there’s nothing else to procrastinate on? as social organizations, libraries, ala, lita and other groups, it appears that we have plucked all the low­hanging fruit of web 1.0. e­mail and static web pages have been done to death. as a pragmatist, what concerns me most is implementation. what delivery systems should and can we adopt and develop to fulfill the promise of services we’d like? can we ensure that barriers to participation are either eliminated or so low as to include everyone? i like to think that web 2.0 is innovation toward mirroring how we personally want to work and play and how we want our social structures to perform. so how can we make lita mirror how we want to work and play? i do know it’s not just making everything a wiki. mark beatty (mbeatty@wils.wisc.edu) is lita president 2007/2008 and trainer, wisconsin library services, madison. president’s column mark beatty 34 information technology and libraries | march 2011 camilla fulton web accessibility, libraries, and the law as a typical student, you are able to scan the resources and descriptions, familiarize yourself with the quiz’s format, and follow the link to the quiz with no inherent problems. everything on the page flows well for you and the content is broken up easily for navigation. now imagine that you are legally blind. you navigate to the webpage with your screen reader, a software device that allows you to surf the web despite your impairment. ideally, the device gives you equal access to webpages, and you can navigate them in an equivalent manner as your peers. when you visit your teacher’s webpage, however, you start experiencing some problems. for one, you cannot scan the page like your peers because the category titles were designed with font tags instead of heading tags styled with cascading style sheets (css). most screen readers use heading tags to create the equivalent of a table of contents. this table of contents function divides the page into navigable sections instead of making the screen reader relay all page content as a single mass. second, most screen readers also allow users to “scan” or navigate a page by its listed links. when you visit your teacher’s page, you get a list of approximately twenty links that all read, “search this resource.” unfortunately, you are unable to differentiate between the separate resources without having the screen reader read all content for the appropriate context. third, because the resources are separated by hard returns, you find it difficult to differentiate between each listed item. your screen reader does not indicate when it approaches a list of categorized items, nor does it pause between each item. if the resources were contained within the proper html list tags of either ordered or unordered (with subsequent list item tagging), then you could navigate through the suggested resources more efficiently (see figures 1, 2, and 3). finally, the video tutorial’s audio tract explains much of the quiz’s structure; however, the video relies on image-capture alone for page orientation and navigation. without a visual transcript, you are at a disadvantage. stylistic descriptions of the page and its buttons are generally unhelpful, but the page’s textual content, and the general movement through it, would better aid you in preparation for the quiz. to be fair, your teacher would already be cognizant of your visual disability and would have accommodated your class needs appropriately. the individuals with disabilities education act (idea) mandates educational institutions to provide an equal opportunity to education.1 your teacher would likely avoid posting any class materials online without being certain that the content was fully accessible and usable to you. unlike educational institutions, however, most libraries are not legally bound to the same law. idea does not command libraries to provide equal access to information through with an abundance of library resources being served on the web, researchers are finding that disabled people oftentimes do not have the same level of access to materials as their nondisabled peers. this paper discusses web accessibility in the context of united states’ federal laws most referenced in web accessibility lawsuits. additionally, it reveals which states have statutes that mirror federal web accessibility guidelines and to what extent. interestingly, fewer than half of the states have adopted statutes addressing web accessibility, and fewer than half of these reference section 508 of the rehabilitation act or web content accessibility guidelines (wcag) 1.0. regardless of sparse legislation surrounding web accessibility, librarians should consult the appropriate web accessibility resources to ensure that their specialized content reaches all. i magine you are a student. in one of your classes, a teacher and librarian create a webpage that will help the class complete an online quiz. this quiz constitutes 20 percent of your final grade. through the exercise, your teacher hopes to instill the importance of quality research resources found on the web. the teacher and librarian divide their hand-picked resources into five subject-based categories. each resource listing contains a link to that particular resource followed by a paragraph of pertinent background information. the list concludes with a short video tutorial that prepares students for the layout of the online quiz. neither the teacher nor the librarian has extensive web design experience, but they both have basic html skills. the library’s information technologists give the teacher and librarian web space, allowing them to freely create their content on the web. unfortunately, they do not have a web librarian at their disposal to help construct the page. they solely rely on what they recall from previous web projects and visual layouts from other websites they admire. as they begin to construct the page, they first style each category’s title with font tags to make them bolder and larger than the surrounding text. they then separate each resource and its accompanying description with the equivalent of hard returns (or line breaks). next, they place links to the resources within the description text and label them with “search this resource.” finally, they create the audiovisual tutorial with a runtime of three minutes. camilla fulton (cfulton2@illinois.edu) is web and digital content access librarian, university of illinois, urbana-champaign. web accessibility, libraries, and the law | fulton 35 providing specifics on when those standards should apply. for example, section 508 of the rehabilitation act could serve as a blueprint for information technology guidelines that state agencies should follow. section 508 states that federal employees with disabilities [must] have access to and use of information and data that is comparable to the access and use by federal employees who are not individuals with disabilities, unless an undue burden would be imposed on the agency.4 section 508 continues to outline how the declaration should be met when procuring and managing software, websites, telecommunications, multimedia, etc. section 508’s web standards comply with w3c’s web content accessibility guidelines (wcag) 1.0; stricter compliance is optional. states could stop at section 508 and only make web accessibility laws applicable to other state agencies. section 504 of the rehabilitation act, however, provides additional legislation to model. in section 504, no disabled person can be excluded from programs or activities that are funded by federal dollars.5 section 504 further their websites. neither does the federal government possess a carte blanche web accessibility law that applies to the nation. this absence of legislation may give the impression of irrelevance, but as more core components of librarianship migrate to the web, librarians should confront these issues so they can serve all patrons more effectively. this article provides background information on the federal laws most frequently referenced within web accessibility cases. additionally, this article tests three assumptions: ■■ although the federal government has no web accessibility laws in place for the general public, most states legalized web accessibility for their respective state agencies. ■■ most state statutes do not mention section 508 of the americans with disabilities act (ada) or acknowledge world wide web consortium (w3c) standards. ■■ most libraries are not included as entities that must comply with state web accessibility statutes. further discussion on why these issues are important to the library profession follows. ■■ literature review no previous study has systematically examined state web accessibility statutes as they relate to libraries. most articles that address issues related to library web accessibility view libraries as independent entities and run accessibility evaluators on preselected library and university websites.2 those same articles also evaluate the meaning and impact of federal disability laws that could drive the outcome of web accessibility in academia.3 in examining state statutes, additional complexities may be unveiled when delving into the topic of web accessibility and librarianship. ■■ background with no definitive stance on public web accessibility from the federal government, states became tasked with figure 1. these webpages look exactly the same to users, but the html structure actually differs in source code view. 36 information technology and libraries | march 2011 title ii, section 201 (1) defines “public entity” as state and local governments, including their agencies, departments, and districts.9 title iii, section 302(a) builds on title ii and states that in the case of commercial facilities, no individual shall be discriminated against on the basis of disability in the full and equal enjoyment of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation by any person who owns, leases . . . or operates a place of public accommodation.10 delineates specific entities subject to the auspice of this law. though section 504 never mentions web accessibility specifically, states could freely interpret and apply certain aspects of the law for their own use (e.g., making organizations receiving state funds create accessible websites to prevent the exclusion of disabled people). if states wanted to provide the highest level of service to all, they would also consider incorporating the most recent w3c recommendations. the w3c formed in 1994 to address the need for structural consistency across multitudinous websites and web browsers. the driving principle of the w3c is to make the benefits of the web accessible to all, “whatever their hardware, software, network infrastructure, native language, culture, geographical location, or physical or mental ability.”6 the most recent w3c guidelines, wcag 2.0, detail web accessibility guidelines that are simpler to understand and, if followed, could improve both accessibility and usability despite browser type. alternatively, states could decide to wait until the federal government mandates an all-encompassing law on web accessibility. the national federation of the blind (nfb) and american council of the blind (acb) have been trying commercial entities in courts, claiming that inaccessible commercial websites discriminate against disabled people. the famous nfb lawsuit against target provided a precedent for other courts to acknowledge; commercial entities should provide an accessible means to purchase regularly stocked items through their website (if they are already maintaining one).7 these commercial web accessibility lawsuits are often defended with title ii and title iii of the ada. title ii, section 202 states, subject to the provisions of this title, no qualified individual with a disability shall, by reason of such disability, be excluded from participation in or be denied the benefits of the services, programs, or activities of a public entity, or be discriminated by any such entity.8 figure 2. here we see distinct variances in the source code. the image at the top (inaccessible) reveals code that does not use headings or unordered lists for each resource. the image on the bottom (accessible) does use semantically correct code, maintaining the same look and feel of the headings and list items through an attached cascading stylesheet. web accessibility, libraries, and the law | fulton 37 accessibility believe that section 301(7) specifically denotes places of physical accommodation because the authors’ original intent did not include virtual ones.13 settling on a definition for “public accommodation” is so divisive that three district courts are receptive to “public accommodation” referring to nonphysical places, four district courts ruled against the notion, and four have not yet made a decision.14 despite legal battles within the commercial sector, state statute analysis shows that states felt compelled to address web accessibility on their own terms. ■■ method this study surveys the most current state statute web presences as they pertain to web accessibility and their connection to libraries. using georgia institute of technology’s state e&it accessibility initiatives database and golden’s article on accessibility within institutions of higher learning as starting points, i searched each state government’s online statutes for the most recently available code.15 examples of search terms used include “web accessibility,” “information technology,” and “accessibility -building -architecture -health.” “building,” for example, excluded statute results that pertained to building accessibility. i then reviewed each statute to determine whether its mandates applied to web accessibility. some statutes excluded mention of web accessibility but outlined specific requirements for an institution’s software procurement. when statutes on web accessibility could not be found, additional searches were conducted for the most recently available web accessibility guidelines, policies, or standards. using a popular web search engine and the search terms “[state] web accessibility” usually resulted in finding the state’s standards online. if the search engine did not offer desirable results, then i visited the appropriate state government’s website. the term “web accessibility” was used within the state government’s site search. the following results serve only as a guide. because of the ever-changing nature of the law, please consult legal advisors within your institution for changes that may have occurred post article publication. ■■ results “although the federal government has no web accessibility laws in place for the general public, most states legalized web accessibility for its respective state agencies.” false—only seventeen states have codified laws ensuring web accessibility for their state websites.16 four this title’s proclamation seems clear-cut; however, legal definitions of “public accommodation” differ. title iii, section 301(7) defines a list of acceptable entities to receive the title of “public accommodation.”11 among those listed are auditoriums, theaters, terminals, and educational facilities. courts using title iii in defense for web accessibility argue that the web is a place, and therefore cannot discriminate against those with visual, motor, or mental disabilities.12 those arguing against using title iii for web figure 3. fangs (http://www.standards-schmandards.com/ projects/fangs/) visually emulates what a standard screen reader outputs so that designers can take the first steps in creating more accessible content on the web. 38 information technology and libraries | march 2011 classified institutions with library websites found that less than half of each degree-producing division was directed by their institution to comply with the ada for web accessibility.24 some may not recognize the significance of providing accessible library websites, especially if they do not witness a large quantity of accommodation requests from their users. coincidentally, perceived societal drawbacks could keep disabled users from seeking the assistance they need.25 according to american community survey terminology, disabilities negatively affecting web accessibility tend to be sensory and self-care based.26 the 2008 american community survey public use microdata sample estimates that 10,393,100 noninstitutionalized americans of all ages live with a hearing disability and 6,826,400 live with a visual disability.27 according to the same survey, an estimated 7,195,600 noninstitutionalized americans live with a self-care disability. in other words, nearly 24.5 million people in the united states are unable to retrieve information from library websites unless web authors make accessibility and usability their goal. as gatekeepers of information and research resources, librarians should want to be the first to provide unrestricted and unhindered access to all patrons despite their ability. nonetheless, potential objections to addressing web accessibility can deter improvement: learning and applying web accessibility guidelines will be difficult. there is no way we can improve access to disabled users in a way that will be useful. actually, more than 90 percent of sensory-accessibility issues can be resolved through steps outlined in section 508, such as utilizing headings properly, giving alternative image descriptions, and providing captions for audio and video. granted, these elements may be more difficult to manage on extensive websites, but wisely applied web content management systems could alleviate information technology units’ stress in that respect.28 creating an accessible website is time consuming and resource draining. this is obviously an “undue burden” on our facility. we cannot do anything about accessibility until we are given more funding. the “undue burden” clause seen in section 508 and several state statutes is a real issue that government officials needed to address. however, individual institutions are not supposed to view accessible website creation as an isolated activity. “undue burden,” as defined by the code of federal regulations, relies upon the overall budget of the program or component being developed.29 claiming an “undue burden” means that the institution must extensively document why creating an accessible website would cause a burden.30 the institution would also have to provide disabled users an alternative means of access to information provided online. of these seventeen extended coverage to include agencies receiving state funds (with no exceptions).17 though that number seems disappointingly low, many states addressed web accessibility through other means. thirtyone states without web accessibility statutes posted some form of standard, policy, or guideline online in its place (see appendix). these standards only apply to state entities, however, and have no legal footing outside of federal law to spur enforcement. at the time of article submission, alaska and wyoming were the only two states without an accessibility standard, policy, or guideline available on the web. “most state statutes do not mention section 508 of the americans with disabilities act or acknowledge world wide web consortium (w3c) standards” true—interestingly, only seven of the seventeen states with web accessibility statutes reference section 508 or wcag 1.0 directly within their statute text (see appendix).18 minnesota is the only state that references the more current wcag 2.0 standards.19 these numbers may seem minuscule as well, but all states have supplemented their statutes with more descriptive guidelines and standards that delineate best practices for compliance (see appendix). within those guidelines and standards, section 508 and wcag 1.0 get mentioned with more frequency. “most libraries are not included as entities that must comply with state web accessibility statutes.” true—from the perspective of a librarian, the above data means that forty-eight states would require web accessibility compliance for their state libraries (see appendix). four of those states (arkansas, california, kentucky, and montana) require all libraries receiving state funds to maintain an accessible website.20 an additional four states (illinois, oklahoma, texas, and virginia) explicitly hold universities, and therefore their libraries, to the same standards as their state agencies.21 despite the commendable efforts of eight states pushing for more far-reaching web accessibility, thousands of k–12, public, and academic libraries nationwide escape these laws’ reach. ■■ discussion and conclusion without legal backing for web accessibility issues at all levels, “equitable access to information and library services” might remain a dream.22 notably, researchers have witnessed web accessibility improvements in a four-year span; however, as of 2006, even libraries at institutions with ala-accredited library and information science programs did not average an accessibility validation of 70 percent or higher.23 additionally, a survey of carnegie web accessibility, libraries, and the law | fulton 39 9. 42 u.s.c. §12131. 10. 42 u.s.c. §12182. 11. 42 u.s.c. §12181. 12. carrie l. kiedrowski,

a blind student, backed by the nfb, initiated litigation against the law school admissions council (lsac) because of the inaccessibility of its online tests.31 in 2010, they added four law schools to the defense: university of california hastings college of the law, thomas jefferson school of law, whittier law school, and chapman university school of law.32 these law schools were added because they host their application materials on the lsac website.33 assuredly, if instructors and students are encouraged or required to use library webpages for assignments and research, those unable to use them in an equivalent manner as their peers may pursue litigation for forcible change. ultimately, providing accessible websites for library users should not be perceived as a hassle. sure, it may entail a new way of thinking, but the benefits of universal access and improved usability far outweigh the frustration that users may feel when they cannot be self-sufficient in their web-based research.34 regardless of whether the disabled user is in a k–12, college, university, or public library, they are paying for a service that requires more than just a physical accommodation.35 federal agencies, state entities, and individual institutions are all responsible (and important) in the promotion of accessible website construction. lack of statutes or federal laws should not exempt libraries from providing equivalent access to all; it should drive libraries toward it. references 1. individuals with disabilities education act of 2004, 40 u.s.c. §1411–§1419. 2. see david comeaux

review and projection brett butler: butler associates, stanford, california. a review and discussion of the technique of automatic format recognition ( afr) of bibliographic data are presented. a comparison is made of the record-building facilities of the library of congress, the university of california (both afr techniques), and the ohio college library center (non-afr). a projection of a next logical generation is described. introduction the technique commonly identified as "format recognition" has more potential for radically changing the automation programs of libraries than any other technical issue today. while the development of marc has provided an international standard, and various computer developments provide increasingly lower operating costs, the investment in converting a catalog into machine-readable form has kept most libraries from integrating automated systems into their operations. the most expensive part of the conversion to machine-readable form has been the human editing required (generally by a cataloger) to identify the many variable portions of the marc-format cataloging record. a full cataloging record contains several hundred possible sections (or fields) in the marc format. research at the library of congress (lc) into this problem resulted in the concept of "format recognition" to reduce cataloging input costs. with the automatic format recognition ( afr) approach, an unedited cataloging entry is prepared (keypunched or otherwise converted to machine-readable form). then the afr computer program provides identification of the various elements of the catalog record through sophisticatedcomputer editing. a degree of human post-editing is generally assumed, but· the computer basically is assigned the responsibility of editing an un.(lae;n.1:itie~d block of text into a marc-format cataloging record. pioneering afr work at the library of congress is presently in use original cataloging input to the marc distribution service. this 28 journal of libm1·y automation vol. 7/1 march 1974 system is quite sophisticated because its output goal is a complete marc record with all fields, subfields, tags, and delimiters identified almost entirely through computer editing. the institute of library research (ilr) at the university of california, faced with the need to convert 800,000 catalog records to marc format, has developed a ·jess ambitious afr program which provides a level of identification sufficient to provide the desired book catalog bibliographic output, or to print catalog cards. . . · the aim of this paper is to examine these two afr strategies and consider their implications for input of two major classes of cataloging records: ( 1) lc or other cataloging records in standard card format; and ( 2) original cataloging not yet in card format. comparing the two afr strategies to an essentially non-afr format used at the ohio college library center for on-line ca:taloging input, we will propose a median strategy for original cataloging. format recognition ( ofr). the thesis is that differing strategies of input should be used for records already formatted into catalog card images and for those original cataloging items being input prior to card production. automatic format recognition an examination of the library of congress ( lc), university of california ( u c), ohio college library center ( oclc), and original format recognition ( ofr) strategies will show the operating differences .. a ·detailed field-by-field comparison of the nearly 500 distinct codes which can be identified in creation of a marc record is attached as appendix i. general comparisons can be made in several areas: input documents, manual coding, level of identification, input and processing costs, error correction, and flexibility in use. input documents-the lc/afr program operates from an uncoded typescript to a machine-readable record prepared through mt /st magnetic tape input. this typescript is, however, prepared from an lc cataloger's manuscript worksheet, in which thereis some inherent bibliographic order.· the lc/ afr program does not rely on this inherent order although its design takes advantage of the probable order in search strategies. lc/ afr could operate with keying of catalog cards, book catalog entries~ or any structure of bibliographic data. the uc program is designed more specifically to handle input of formatted catalog cards, and some of its afr strategy is based on· the sequence and physical indentation pattern on standard catalog cards. it would not work effectively on noncard format input without special recognition of some tagging conventions. the oclc program allows direct input to crt screen from any input docutnent; it requires complete identification of each cataloging field or subelement input. automatic fo1'mat recognition/butler 29 manual coding-lc/ afr requires minimal input coding. within the title paragraph, the title proper, the edition statement, and imprint are explicitly separated at input. series, subject, and other added entries are recognized initially from the roman and arabic numerals preceding them. aside jrom these items, virtually all marc fields are recognized by the computer editing program. uc/ afr inserts a code after the call number input, thus providing explicit identification at input. it also identifies each new indentation on the catalog card explicitly, thus implicitly identifying main entry, title, and certain other major cataloging blocks on the card. the oclc input specifications require explicit coding, some of which is prompted by the crt screen. level of identification-lc/ afr provides the highest possible level of marc record identification, deriving practically every field, subfield, and other code if it is present in an individual cataloging record.~ in evaluation of this element of lc/ afr it should be realized that the needs of the library of congress in creating original marc records for nationwide distribution (and its own use) are much more sophisticated and complex than those of any individual user library or system. the uc/ afr approach reflects a more task-oriented approach, deriving a sufficient level of identification to separate major bibliographic elements. this technique is clearly sufficient to produce computer-generated catalog cards or similar output in a standard manner. however, ucjafr lacks several identifiers, such as specific delimitation of information in the imprint field, which would make feasible the use of its records for further computer-generated processes. the oclc input format is of variable level; many elements are optional and are noted with an asterisk in appendix i. at its most complete, the oclc format specifically excludes only a very few marc fields, most notably geographic area and bibliographic price. input and p1'ocessing costs-direct cost information has not been published for production costs of any of the format recognition systems. the library of congress has reported that ..... the format recognition technique is of considerable value in speeding up input and lowering the cost per record for processing."3 while formal reports have not been published, informed opinion has placed the cost of creation of a marc record at a level of $3.00 ± $.50. format recognition is credited with an increase in productivity of about one-third on input keying and an increase of over 80 percent in human editing/proofreading, and actual computer 0 a number of standard subdivi'sions of various fields were first announced as part of the marc format in the 5th edition of books: a marc format, which was published in 1972.1 consequently they are not specified in format recognition process for marc records, published in 1970, which was used as the reference for this paper.2 they are, however, clearly subfields which could be identified by expansions of afr. these elements are marked with a lower-case "r" in appendix i. 30 journal of libtary automation vol. 7/1 march 1974 processing times approximate those achieved with earlier library of congress marc processing programs.4 lt would seem that afr may have lowered library of congress marc processing costs to the level of $2.00 ± $.50. in the final report of the recon pilot project, cost simulation projections for full editing and format recognition editing were given as $3.46 and $3.06 per record, respectively.6 while full cost information has not been derived for the uc/ afr program itself, figures have been informally reported at library automation meetings indicating that the cost of record creation was approximately $1.00 per entry. included in this figure is computer editing of name and other entries against a computerized authority file, which is done manually in the lc/ afr system. this program is undeniably the least-cost effort to date providing a marc-format bibliographic record. no cost data are provided on the oclc on-line input system. it can be observed that the coding required is quite similar to the pre-afr system in use at the library of congress itself, and that on-line crt input had been evaluated at lc as a higher-cost input technique than the magnetictape typewriters currently providing marc input. lc is considering, though, on-line crt access for subsequent human editing of the marc record created through off-line input and afr editing. error rate and correction-any afr strategy, with present state of the art, generates some error above the normal keying rate observed with edited records. the strategy aims for lowest overall cost by catching these errors in a postprocessing edit which must be performed even for records edited prior to input. the library of congress reports, "the format recognition production rate of 8.4 records per hour (proofing only) . . . is slightly less than that (about 9.2 per hour) for proofing edited records. with format recognition records, the editors must be aware of the errors made by the program ... as well as keying mistakes."6 the savings in prekeyboard editing and increased keying rates more than make up for this slight decrease in postprocessing editing. at the library of congress, where afr is used for production of marc records, a full editing process aims at 100 percent accuracy of input. while such a goal is statistically unreachable, considerable effort· is expended by the marc distribution service to provide the most accurate output possible. from a systems perspective, errors existing in marc records are perhaps less reprehensible than errors in printed bibliographic output, simply because the distributed marc record can be updated by subsequent distribution of a "correction" record. it should be noted that some marc subscribers have voiced concern about the increased percentage of "correction" records, which the library of congress indicates come primarily from cataloging changes rather than input edit errors. the uc/ afr program clearly takes a statistical approach to bibliographic element input and processing. shoffner has indicated that the scale of the 1,000,000 record input project caused a reevaluation of the feasibility of traditional procedures. 7 the result is, in the uc/ afr implementaautomatic format recognition/butler 31 tion, a marc record essentially devoid of human editing. for a smaller scale of production, the uc approach could be combined with post-editing such as that used at lc to increase overall file accuracy. in passing, however, it should be noted that rather sophisticated verification techniques are used in the uc/ afr approach which could be of value in future approaches. these include, for instance, comparison of all words against a machine-readable english-language dictionary; words not found in the dictionary are output for manual editing as suspected keypunch errors. little information is available on the error rates and corrections in the oclc system. however, most records keyed to the oclc system are for a local member's catalog card production, so feedback is provided and presumably errors are corrected through re-inputting to obtain a proper set of catalog cards. there is no central control on the quality of locally entered oclc records at present, except for the encoding standards developed by oclc. flexibility in use-a number of considerations are appropriate herehow many types of format (catalog cards, worksheets, etc. ) can be used as input, how many possible outputs can be developed from the derived marc format, how adaptable is the system to remote and multiple input locations, how many special equipment restrictions are there? the lc/ afr program is clearly the most flexible in ability to accept varying inputs and provide a flexible output. it is, however, not capable of any authority-file editing at present (this is done manually against lc's master files before input). while the input form could be used rather easily at remote locations, the marc afr programs themselves are not available for use outside the library of congress. the uc/afr program provides a rather minimal set of cataloging element subfields but does provide more sophisticated textual editing within the program. it is quite adaptable to remote input as long as the original "worksheet" is in catalog card format, a restriction which in effect requires a preinput human editing step for original cataloging input. the marc format provided would not be sufficient for some currently operating programs using the full marc format, but is quite sufficient for most bibliographic outputs. the oclc input program is dependent on visual editing at the time of crt keying. its flexibility in input is considerable, and outputs can approach a full marc record if all optional fields are identified. original format recognition a working conclusion of this review is that an afr program developed according to the strategy of the university of california will deliver a satisfactory marc-format record at a lower cost than other afr or nonafr alternatives. however, much of the efficiency of the ucjafr is based on the presence of an already existing lc-format catalog card from which to keyboard machine-readable data. for original cataloging to be keyboarded from a cataloger's worksheet, 32 journal of library automation vol. 7/1 march 1974 an original format . recognition strategy is proposed which · provides a somewhat more detailed format than the uc/ afr marc while retaining a generally flexible system and low input costs. several system considerations also guide the design of an ofr system designed for relatively general-purpose user input and multiple output functions: • no special equipment requirements for input keying; • no special knowledge of the marc format required; • minimal table-lookup or text searching in processing; • flexible options for depth of coding provided; and • sufficient depth of format derived for most applications. the ofr input strategy outlined in appendix i provides a much greater degree of explicit field coding at input than the afr programs outlined above. the basis for this decision is the judgment that this cataloging, being done originally by a professional, can readily be coded by element name prior to input. no effort is made to identify marc field elements which· occur with very low frequency, or which are of limited utility for most applications. for instance, the "meeting" type of entry occurs in all combinations, in only 1.8 percent of all records studied by the library of congress in its format recognition study. 8 marc elements requiring either extensive human editing or complex computer processing are likewise excluded from input, on a cost-utility basis. an example is the geographic area code, which must either be assigned by a knowledgeable editor or derived through extensive computer searching for the city /county of publication. however, where little penalty is attached to allowing input of coded information, the ofr format allows input for inclusion in the derived marc-format record. conclusion it is clear that the afr programs developed for specific needs by the library of congress and the university of california can be great factors for change in library automation strategies over the next decade. striking benefits in cost savings, ease of input, and subsequent processing are to be gained. the abbreviated outline of an original cataloging ( ofr) input strategy is simply a suggestion of a second generation of format recognition programs which will undoubtedly develop to serve more general needs for marc-format bibliographic input. references 1. u.s. library of congress, marc

(any resemblance between my fictional author and a real potential author is purely coincidental.) lucky me: we all know that such an incident is not unthinkable in library land. lucky lita: it is unlikely that any member will cancel his or her membership or any subscriber, his, her, or its subscription because the technical term “scro­ tum” found its way into my editorial. ital is, after all, a technology journal, and members and readers ought to be offended if our journal abjures technical terminology. likewise they should be offended if our articles discuss library technology issues misusing technical terms or concepts, or confusing technical issues with policy issues, or stating technology problems or issues in the title or abstract or introduction then omitting any mention of said problems until the final paragraph(s). ital referees are quite diligent in questioning authors when they think terminology has been used loosely. their close readings of manuscripts have caught more than one author mislabeling policies related to the uses of informa­ tion technologies as if the policies were themselves tech­ nical conundrums. most commonly, they have required authors who state major theses or technology problems at the beginnings of their manuscripts, then all but ignore these until the final paragraphs, to rewrite sections of their manuscripts to emphasize the often interesting questions raised at the outset. what, pray tell, is the editor trying to communicate to readers? two things, primarily. first, i have been following with interest the several heated discussions that have taken place on lita­l for the past number of months. sometimes, the idea of the traditional quarterly scholarly/professional journal in a field changing so rapidly may seem almost quaint. a typical ital article is five months old when it is pub­ lished. a typical discussion thread on lita­l happens in “real time” and lasts two days at most. a small number of participants raise and “solve” an issue in less than a half dozen posts. a few times, however, a question asked or a comment posted by a lita member has led to a flurry of irrelevant postings, or, possibly worse, sustained bomb­ ing runs from at least two opposing camps that have left some members begging to be removed from the list until the all clear signal has been sounded. i’ve read all of these, and i could not help but won­ der, what if ital accepted manuscripts as short as lita­l postings? what would our referees do? i suspect, for our readers’ sakes, most would be rejected. authors whose manuscripts are rejected receive the comments made by the referees and me explaining why we cannot accept their submissions. the most frequent reason is that they are out of scope, irrelevant to the purposes of lita. when someone posts a technology question to lita­l that gener­ ates responses advising the questioner that implementing the technology in question is bad policy, the responses are, from an editor’s point of view, out of scope. how many lita members have authority—real authority—to set policy for their libraries? a second “popular” reason for rejections is that the manuscripts pose “false” problems that may be technological but that are not technologies that are within the “control” of libraries. these are out of scope in a different manner. third, some manuscripts do not pass the “so what” test. some days i wish that lita­l responders would referee, honestly, their own responses for their relevance to the questions or issues or so­whatness and to the membership. second, and more importantly to me, lita members, whether or not your bodies include the part that we all have come to know and defend, do you have the “­” to send your ital editor a manuscript to be chewed upon not by rattlesnakes but by the skilled professionals who are your ital editorial board members and referees? i hope (and do i dare beg again?) so. your journal will not suffer quaintness unless you make it so. editorial: the virtues of deliberation john webb john webb (jwebb@wsu.edu) is a librarian emeritus, washington state university, and editor of information technology and libraries. editorial | webb 3 selecting a web content management system for an academic library website | black 185 others. the osu libraries needed a content management system (cms). web content management is the discipline of collecting, organizing, categorizing, and structuring information that is to be delivered on a website. cmss support a distributed content model by separating the content from the presentation and giving the content provider an easy to use interface for adding content. but not just any cms would work. it was important to select a system that would work for the organization. the focus of this article is the process followed by osu libraries in the selection of a web cms. other aspects of the project, such as the creation of the user focused information architecture, the redesign of the site, the implementation of the cms, and the management of the project are outside the scope of this article. ■■ literature review content and workflow management for library web sites: case studies, a set of case studies edited by holly yu, a special issue of library hi tech dedicated to content management, and other articles effectively outlined the need for libraries to move from static websites, dominated by html webpages, to dynamic database and cms driven websites.1 each of these works noted the messy, unmanageable situation of the static websites in which the content is inconsistently displayed and impossible to maintain. seadle summarizes the case well when he wrote “a content management system (cms) offers a way to manage large amounts of web-based information that escapes the burden of coding all of the information into each page in html by hand.”2 a cms provides an interface for content providers to add their contributions to the website without requiring knowledge of html; it separates the layout and design of the webpages from the content and provides the opportunity for reuse of both content and the code running the site. these features of a cms permit a library to professionalize its website by enforcing a consistency of design across all pages while at the same time increasing efficiency by making the maintenance of the content itself less technically challenging.3 the potential of the cms is powerful, yet it is not an easy process to select and implement a cms. one challenge is that the process of selecting and implementing a cms is not a fully technical one. the selection must be tied to the goals and strategy of the library and parent elizabeth l. black selecting a web content management system for an academic library website this article describes the selection of a web content management system (cms) at the ohio state university libraries. the author outlines the need for a cms, describes the system requirements to support a large distributed content model and shares the cms trial method used, which directly included content provider feedback side-by-side with the technical experts. the selected cms is briefly described. i magine a city that has been inhabited consistently for hundreds, perhaps thousands of years. those arriving in the city’s main port follow clear, wide paths that are easy to navigate. soon, however, the visitor notices that the signs change. they look similar but the terms are different and the spaces have an increasingly different look. continuing further, the visitor is lost. some sections look drastically different, as if they belong in an entirely different city. other sections are abandoned. the buildings at first seem occupied, but upon closer inspection all is old and neglected. the visitor tries to head back to the main, clear sections but cannot find the way. in frustration, the visitor leaves the city and moves on, often giving up the mission that led to the city in the first place. this metaphor describes the state of the ohio state university (osu) libraries’ website at the beginning of this project. the website has many content providers, more than 150 at one point. these content providers were given accounts to ftp files to the web server and a variety of web editors with which to manage their files. the site consisted of more than 100,000 files of many types: html, php, image files, microsoft office formats, pdf, etc. the files with content were primarily static html files. in 2005, the osu libraries began to implement a php-based template that included three php statements that called centrally maintained files for the header, the main navigation, and the footer. the template also called a series of centrally controlled style sheets. the goal was to have the content providers add the body of the pages and leave the rest to be managed by these central files. this didn’t work as intended. because of a combination of page editing practices learned with static html and a variety of skill with cascading style sheets (css), many pages lost the central control of the header, menu, and footer. also, the template was confusing for many because they had to wade through a lot of code they didn’t understand. one part of this content model was right—giving the person with the content knowledge the power to update the content while centrally controlling parts that should remain consistent throughout the website. unfortunately, the technical piece of the model didn’t support this goal. it required too much technical knowledge from the content providers. the real solution was a system that would allow the content providers to focus on their content and leave the technical knowledge to elizabeth l. black (black. 367@osu.edu) is head, web implementation team, ohio state university libraries, columbus, ohio. 186 information technology and libraries | december 2011 and interviews/focus groups with the current content providers. the research was similar to that described previously in the literature review section of this article. the most helpful for this project was a 2006 issue of library hi tech focused on cmss.10 the most useful of these articles was wiggins, remley, and klingler’s article about the work done at kent state university, particularly the way in which they organized their requirements.11 a working group of four served as interviewers for the focus groups with current web content providers. they worked in pairs, with one serving as a recorder and the other as the facilitator, who asked the questions. fifteen interview sessions were held over a period of three months. the focus group participants were invited to participate in like groups as much as possible, so for example the foreign language librarians were interviewed together in a different session from the instruction librarians. however, no one participated more than once in an interview. the same set of guiding questions was used for each interview. they are included in the appendix. the results of these interviews became the basis for the requirements document to which the technical team added the technical requirements. ■■ the cms requirements the requirements were gathered into five categories: content creation and ownership, content management, publishing, presentation, and administration/technical. these categories were modeled after those used for the project at kent state university.12 the full list is detailed below by category. content creation and ownership requirements ■■ separation of content and presentation: the content owners can add and edit content without impact on the presentation ■■ web-based gui content-editing environment that is intuitive and easy to learn without knowledge of html ■■ metadata created and maintained for each webpage or equivalent content level that contains: ■❏ owner ■❏ subject terms or tags describing the content ■■ multi-user authoring without overwriting ■■ can handle a large number of content providers (approximately 200) ■■ can integrate rss and other dynamic content from other sources ■■ can handle different content types, including: ■❏ text ■❏ images organization, must meet specific local requirements for functionality, and must include revision of the content management environment, meaning new roles for the people involved with the website.4 karen coombs noted that “the implementation of a content management system dramatically changes the role of the web services staff” and requires training for the librarians and staff who are now empowered to provide the content.5 another challenge was and continues to be a lack of a turn-key library cms.6 several libraries that did a systematic requirements gathering process generally found that the readily available cmss did not meet their requirements, and they ended up writing their own applications.7 building a cms is not a project to take lightly, so only a select few libraries with dedicated in-house programming staff are able to take on such an endeavor. the sharing of the requirements of these in-house library specific cmss is valuable for other libraries in identifying their own requirements. in the past few years, the field of open-source cmss has increased, making it more likely that a library will find a viable cms in the existing marketplace that will meet the organization’s needs. drupal is an open-source cms that was one of the first viable options for libraries and so is widely used in the library community. it was the subject of an edition of library technology reports in 2008.8 since drupal opened the door for open-source cmss in libraries, others have entered the market as well. in 2009 john harney noted, “there are few technologies as prolific as web content management systems. some experts number these systems in the 80-plus range, and most would concede there are at least 50.”9 the cms selection process described here builds on those described in the literature by integrating their requirements and methods to address the needs of a very large decentralized website. it builds on the increased emphasis on user involvement in technology solution building and selection by fully incorporating the cms users in the selection process. further, the process described here took place after those described in the literature, after the opensource cms field had significantly improved. the options were much greater at the time of this study and this article describes the increased possibilities of second generation cmss. while there still does not exist the perfect library ready turn-key cms, there are many excellent, robust open-source cmss available. this article describes one process for selecting among them, including an in-depth trial of three major systems: drupal, modx, and silverstripe. ■■ gathering requirements there were two parts to the requirements gathering process undertaken at osu libraries: research of the literature selecting a web content management system for an academic library website | black 187 ■■ meets established usability standards ■■ dynamic navigation generated for main and subsections of website that includes breadcrumbs and menus ■■ searching ■❏ search engine for website ■❏ can pass searches on to other library web servers ■■ mobile device friendly version (optional) ■■ delivery presentable in the browsers used most heavily by osu libraries websites visitors ■■ page load time is acceptable ■■ easy search engine optimization administration ■■ lamp (linux, apache, mysql, php) platform ■■ good documentation for technical support and end users ■■ scalable in terms of both content and traffic ■■ skills required to maintain system are available at osul the next step was to take this extensive requirements list and identify cmss that would be appropriate for a side-by-side test with both content providers and systems engineers. ■■ cms trial the web cms would become a critical part of the web infrastructure so it was important to ensure selection of the best system for both the content providers and the it team. between may 21 and august 29, 2008, two groups worked with the cmss, testing them on criteria taken from the initial requirements documents. the first team included fourteen content providers with diverse content areas and diverse technical skills; this group rated each system on a content providers set of criteria. the second team, which included the systems engineer and a technical support specialist, rated each system on a set of criteria that was more technical in nature. each participant used a microsoft excel spreadsheet containing requirements condensed from the full list. they rated each system on a scale of 1 to 3 for each criterion, where 1 was difficult, 2 was moderate, and 3 was easy. the project manager in the it web team led the trial. the criteria given to the content providers were: ■■ web gui intuitiveness ■■ media integration ■■ editor ease of use ■■ ability to add content ■■ ability to preview content ■■ ability to publish content ■■ metadata storage ■❏ videos ■❏ camtasia/captivate tutorials ■❏ flash files ■■ content owners can create tables and/or databases for display of tabular data in the web gui interface ■■ content owners can create forms in the web gui interface ■■ option for faculty and professional staff to have webpages featuring their work and their profiles ■❏ all staff must have some control over the personal information available about them on the public website content management ■■ link maintenance ■❏ does not allow internal pages to be deleted if linked to by another cms page ■❏ can regularly check the viability of external links ■❏ periodic reminders to content owners to check their content ■■ way to repurpose content elements to multiple pages for content such as: ■❏ descriptions of article and research databases ■❏ highlight or feature content elements ■■ access controls ■❏ that allows content owners to only edit their content ■❏ that allow web liaisons to provide first line support for their departments ■❏ integrates into our existing security structures (shibboleth) ■■ robust reporting features ■❏ integration with quality web analytics software ■❏ content update tracking ■❏ system usage ■❏ customized report creation publishing ■■ ability to preview before publishing ■■ cms can produce rss feeds for dynamic sections of content ■■ page templates and style sheets are used to control page layout and design centrally ■■ display non-roman scripts using unicode ■■ extensible—can incorporate non-cms content into the site ■■ ability to add personalization options for site users presentation ■■ meets ada and w3c accessibility requirements ■■ code validates to current html specifications 188 information technology and libraries | december 2011 on the technical requirement that the system be easy to extend and integrate. a simple website served as the hub for the cms trial. the site included links to each cms instance, a link to the project blog for updates from the project team, and a link to a wiki space where trial participants shared ideas and thoughts with one another. the web team’s issue tracking system was integrated into this site so participants could easily ask questions of the technical team and report problems. time was set aside each week to handle all reported issues. of the sixteen participants who started the trial, thirteen completed a criteria spreadsheet. the project manager totaled and then averaged the scores provided by each group to determine the overall content provider score and the overall technical score (see figure 1). in the end, both the content providers and the systems engineers agreed that silverstripe was the cms that best met the requirements. ■■ silverstripe silverstripe was released as an open-source cms in november 2006 by silverstripe limited. they had developed the cms as part of their business of creating websites for clients. the company was founded in 2000 and is headquartered in wellington, new zealand. the company continues to use the cms for their website business and also offers paid support for the cms. the testers agreed that silverstripe provided the best match in the areas of easy content creation by multiple authors, handling multilingual content, management of different types of content and content files, search engine optimization, and meeting web standards. a strong and growing open-source community and strong documentation were additional keys to the selection of silverstripe.14 use by high-profile clients, such as the 2008 democratic national convention, provided proof that silverstripe could handle high traffic. the content providers praised silverstripe for the intuitive user interface, the system’s ease of use, specifically the ease of previewing and publishing content. they also noted that silverstripe handled the metadata supporting the pages as well as tabular and form page content better than the other systems. the technical evaluators noted silverstripe’s modular structure, which makes it flexible enough to integrate easily with existing web applications and accommodate local customizations without modifying the core system. silverstripe includes a template language, which fully separates the content from the presentation. in practice, this means that even informed users cannot spot a silverstripe website through simple web browsing, as is common with other cmss. ■■ ability to “feature items” ■■ ability to add rss feeds ■■ ability to enter tabular data ■■ ability to create forms ■■ testing area for new features the criteria given to the systems engineers were: ■■ installation ■■ maintainability ■■ technical documentation ■■ active developer community ■■ structure management (subsites/trees) ■■ access control/permissions ■■ link management ■■ ease of extensibility ■■ interoperability (data portability and web services) the cms requirements document was used in conjunction with the cmsmatrix (http://cmsmatrix.org) website to select five cmss to participate in a trial.13 the five systems selected were drupal 6.2, modx 0.9.6, silverstripe 2.2.2, plone 3.0.6, and typo3. the systems engineer installed all five cmss on a development server and did a simple configuration to make each operational for testing. it was at this stage that plone and typo3 were dropped from the trial because they took too long to configure and set up. the goal was to do a simple installation of the base cms, without any modules, but some systems were not functional as a cms without some modules so we added modules selectively. at the point of the selection of the systems for the trial, the project leaders noted that the entire list of requirements could not be met by an existing cms. they also noted that the majority of the key needs could be met with an existing system. therefore the goal remained to select an existing open-source web cms with the emphasis figure 1. cms trial scores selecting a web content management system

give web content authors direct access to maintain their content without burdening them with the requirement of technical expertise in html. excellent sites also offer a consistent user experience facilitated by centrally managed presentation. a web cms facilitates this model. the selection of a web cms is not solely a technical decision; it is most effective when made in partnership with the web content providers. the process followed by osu libraries described here provides an example of one such selection process. ■■ acknowledgements the author thanks james muir and jason thompson for

first hints of spring on the alberta prairie are manifest. alternatively, perhaps it’s just that the longer and warmer days are causing me to “think spring.” there are no signs yet of early bulbs—at least, none that i can detect with around a foot of snow in most places—but the sun is now rising at 7:30 a.m. and not setting until 6 p.m., a dramatic change from the barely seven hours of daylight typical of december and january. and while none but the hardiest souls are yet outside in shorts and shirt-sleeves, somehow, daytime highs that hover around freezing seem downright pleasant in comparison with the minus thirties (not counting the wind chill) we were experiencing even a couple of weeks ago. yes, spring is in the air, even if the calendar says it is still nearly a month away. . . . so what, you may fairly ask, does the weather in edmonton have to do with ital? this is my first issue of ital as editor, and it may not surprise you to hear that i’ve been thinking quite a bit about what might be the right theme and tone for my first column. while i’ve been associated with the journal for quite awhile—first as a board member, and more recently as managing editor—my role has always been comfortably limited to background tasks such as refereeing papers and production issues. now, that is about to change; i am stepping a bit out of my comfort zone. it’s about beginnings. i follow with some awe in the footsteps of a long line of editors of ital (and jola, its predecessor). i’ve been honored to serve—and to learn a great deal—from the last two, dan marmion and john webb. you, the readers of ital, and i are fortunate to have as returning managing editor judith carter, who preceded me and taught me the skills required for that post; i hasten to emphasize that she is definitely not responsible for the things i did not do right in the job! regular readers of ital will recall that john webb often referred humorously and admiringly to the members of the ital editorial board as his “junkyard dogs;” he claimed that they kept him honest. with the addition of a couple of fine new members, i’m confident that they will continue to do so in my case! okay, with that as preface, enough about me . . . let’s talk about ital. ■ what’s inside this issue ital content has traditionally represented an eclectic blend of the best mainstream and leading/bleeding edge of library technology. we strive to be reflective of the broad, major issues of concern to all librarians, as well as alert to interesting applications that may be little more than a blip at the edge of our collective professional radar screen. our audience is not limited to those actively working in library technology, although they certainly form ital’s core readership; rather, we seek to identify and publish content that will be relevant to all with an interest in or need to know about how technology is affecting our profession. thus, some articles will resonate with staff seeking new ways to use web 2.0 technologies to engage our readers, while other articles will be of interest to those interested in better exploiting the four decades’ worth of bibliographic metadata that forms the backbone of our integrated library systems. the current issue of ital is no exception in this regard. we lead off with two papers that reflect the renewed interest of the past several years in the role and improvement of the library online catalog. jia mi and cathy weng review opac interfaces, searching functionality, and results displays to address the question of why the current opac is ineffective and what we can do to revitalize it. timothy dickey, in a contribution that received the 2007 lita/ exlibris student writing award,1 summarizes the challenges and benefits of a frbr approach to current and “next-gen” library catalogs. interestingly, as will become clear at the end of this column, dickey’s is not the first prize-winning frbr study to appear in the pages of ital. online learning has long been a subject of interest both to librarians and to the education sector as a whole. whereas the focus of many previous studies has been on the techniques and efficacy of online learning systems, though, connie haley’s paper takes a rather different approach, describing and exploring factors that characterize the preference of learners for online training, as compared with more traditional in-person techniques. in gary wan’s and zao liu’s investigation of contentbased information retrieval (cbir) in digital libraries, the authors describe and argue for systems that will enable identification of images and audio clips by automated comparison against digital libraries of image and audio files. finally, wooseob jeong prototypes an innovative application for enhancing web access by the visually impaired. jeong’s application makes use of force feedback, an inexpensive, proven technology drawn from the world of video gaming. ■ some ideas about where we are going a change of editorship is always one of those good opportunities for thinking about how we might improve, or of marc truitt (marc.truitt@ualberta.ca) is associate director, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 4 information technology and libraries | march 2008 different directions we might explore. with that in mind, here are a couple of things we’re either going to try, or that we’re considering: different voices. ital’s format has long included provision for two “opinion” columns, one by the editor, and another by the president of lita. from time to time, past editors have given over their columns for guest editorials. however, there are many other voices that could enrich ital’s pages, and the existing structure doesn’t really have a “place” for the regular airing of these voices. beginning with the june 2008 issue, ital will include a regular column contributed by members of the board, on a rotating basis. the column will be about any topic related to technology and libraries that is on the author’s mind. i’m thinking about how we might expand this to include a similar column contributed by ital readers. while such reader contributions may lack the currency of a weblog, i think that they would make for thoughtprovoking commentary. oh, and there’s that “currency thing.” in recent years, those of us who bring you ital have—as have those responsible for other ala publications—discussed at length the whole question of when and how to move to a sustainable model of electronic publishing that will address the needs of readers. this issue is of course especially important in the case of a technology-focused journal, where content tends to age rapidly. unfortunately, for various reasons, we’re not yet at the stage where we can go completely and solely electronic. a recent conversation with one board member, though, surfaced an idea that i think in the meantime has merit: essentially, we might create a preprint site for papers that have been accepted and edited for future publication in ital. we might call it something such as ital express, and its mission would be to get content awaiting publication out and accessible. is this a “done-deal”? no, at this stage, it’s just an intriguing idea, and i’d be interested in hearing your views about it . . . or anything else related to ital, for that matter. you can e-mail me at marc.truitt@ualberta.ca. ■ and finally, congratulations dept. last week, martha yee, of the film and television archive at the university of california, los angeles received the alcts cataloging and classification section’s margaret mann citation for 2008. martha was “recognized for her outstanding contributions to the practice of cataloging and her interest in cataloging education . . . [and her] professional contributions[, which] have included active participation in ala and alcts and numerous publications.” of particular note, the citation specifically singled out her work in the areas of “frbr, opac displays, shared cataloging and other important issues, [in which] yee is making a significant contribution to the discussions that are leading the development of our field.” surely among the most important of these is her paper “frbrization: a method for turning online public finding lists into online public catalogs,” which appeared in the june 2005 issue of ital (p. 77–95). archived at the ital site, d-list, the cdl e-scholarship repository, and elsewhere, this seminal contribution has become one of the most accessed and cited works on frbr. we at ital are proud to have provided the original venue for this paper and congratulate martha on being named recipient of the margaret mann award. editorial board thoughts: reinvesting in our traditional personnel through knowledge sharing and training mark dehmlow information technology and libraries | december 2017 4 mark dehmlow (mdehmlow@nd.edu) is a member of the ital editorial board and director of library information technology, hesburgh library, university of notre dame, south bend, indiana. lately i have been giving a lot of thought to how those of us in technology positions can extend our impact throughout our organizations. with finite budgets and time and relatively low personnel turnover, i have realized that the solution goes beyond merely finding ways that technology can optimize workflows through automation. i have been working in academic library technology for nearly 20 years and when i began my career, virtually all areas of technology required specialized staff – from supporting general computer applications to managing the technical infrastructure that underlay our core systems. these days, technology is still a specialty, but the function of technicians has become more focused on providing infrastructure and much of the general application support we used to provide has become ubiquitous and has become an expectation of almost all library positions. managing email, creating specialized formulas for data analysis, navigating operating systems, even developing basic databases, are now regular parts of library work. the trend of technological infusion will continue but instead of general technical tasks, almost all new library positions will require deeper technical skills. this is due, in part, to the function of knowledge work becoming more specialized as libraries focus on the areas where they can create the most value and those new domains require more technical expertise to be effective. perhaps the most striking example of this evolution is in the transition of catalogers to metadata specialists. the days of working with a single metadata format (marc) in a single, tabular interface (catalog) are quickly slipping away and being replaced by metadata structured in multiple complex schemes, expressed in formats like xml and json. instead of acquiring data from oclc, libraries need to work with web-based apis to harvest metadata. and the tools for manipulation require basic programming skills in languages like python or working with open source applications that look little like the integrated library systems we are used to. working with these tools can enable metadata experts to customize metadata at scale, but it requires new knowledge and even new ways of thinking about metadata and metadata manipulation. cataloging isn’t the only position undergoing change in academic libraries, either. acquisitions is pushing toward greater automation and patron driven selection. the catalog is becoming more like a bookstore and the discovery landscape includes a panoply of resources that are purchased only at the point a user clicks on a link to a resource. acquisitions is also occurring at larger scale, and requiring the ability to work with thousands of items in a batch, to select based on the qualities of what libraries want to make available, to analyze usage trends, and to load, update, and remove metadata as quickly from our discovery environment as possible. the tools to accomplish this are similar to those for metadata. beyond technical services, we’re beginning to see the role of the subject selector transition from building broad disciplinary collections toward a focus on curation editorial board thoughts | dehmlow 5 https://doi.org/10.6017/ital.v36i4.10239 of specialized collections requiring digitization and digital curation. the tools to accomplish this are digital asset management systems and web-based digital exhibition tools which are specialized content management systems. subject selectors are transforming into digital content creators and managers. technologically-driven change regularly outpaces generational personnel turnover in libraries, and given that technological change continues to grow exponentially, it is clear we need a flexible workforce and an organizational commitment to training and professional growth. while organizations are rewriting positions to include technical skills, we will always have a preponderance of staff that started their careers in libraries with depreciating skillsets. merely directing staff to webinars, conferences and self-driven development isn’t enough. multi-day workshops are great as long as there are opportunities to apply learning upon returning to work. to guarantee skill retention, sustained training needs to be directed towards the specific skills needed now and based in actual work, not just theoretical exercises. the challenge, then, becomes how to implement such a program and identifying who can provide the necessary training. how can specialization be disseminated to non-specialists? many libraries have some of the needed resources close at hand, even if staffing is thin and technical resources scarce. it requires thinking a bit pragmatically to reuse the resources libraries do have, and for technologists to evolve with demands as well, transitioning our roles from technology experts alone to a hybrid of practitioners, teachers, and enablers. teaching is, itself, a specialty and many it professionals are unlikely to have developed that skillset. most libraries, though, have staff who do have experience and expertise in training and pedagogy. evolving towards in-sourced technology development will undoubtedly require it staff to first learn effective teaching methods and basic curricula development. they will need a framework to take a set of specific skills and build ad-hoc courses with medium range learning objectives. teaching can occur in the context of actual work scenarios so that learning is put to practical use as part of that training, and skills retention improved. libraries can become labs for cross-training and knowledge sharing through leveraging our teachers and technologists in interdisciplinary partnerships and collaboration with a focus on internal growth so that library organizations can meet continuously changing demands. once staff have been trained in new technical areas, there is another opportunity for it professionals to extend their impact, by dividing technology-driven projects into the parts that require deep technical work and the parts that require transferable technical skills. if technologists start looking at ways to implement technical solutions in componentized ways instead of as end-to-end solutions, they have the opportunity to empower newly trained staff to contribute in practical ways through building solution foundations and then delegating configurable application inputs. as an example – developing a full application stack requires considerable programming skill, but learning to create and update extensible stylesheets to transform xml-based metadata is a teachable skill. it professionals could develop applications that take a configuration file and an xsl file as inputs while staff with xslt training can modify the configuration to include parameters for connecting to apis or loading xml. trained staff could then modify the xsl to transform data to their specifications without having to pass the task back to the it professional. information technology and libraries | december 2017 6 moving toward more holistic technology capability in libraries will require all personnel to be committed to evolving to meet the emerging needs of our organizations – it professionals included. for decades, technologists have been in the privileged position of having the necessary skills to advance the profession’s digital future, but it will be important for technologists in libraries to integrate the many valuable skills other personnel can offer so that they also can evolve in ways that best support our organizations – leveraging foundational library skills to enhance overall organizational capacity to accomplish tasks that are increasingly requiring technical expertise. i won’t pretend it will be easy. it will require libraries to prioritize organizationally-led training, even amidst the flurry of demands around us, but i think it is also critical to the future of the profession, and the old adage that winter pays for summer feels apropos here. technologists will need to be open to incorporating foundational library skills, to collaborating and learning from other library specialists, to thinking of their positions more broadly, and, for those who live in ivory towers (you know who you are), to eliminating the silos they’ve built and collaborate, cooperate, and engage. technologists are an important part of library ecosystems with what we contribute operationally, but i think we can have a greater impact if we propagate our knowledge in an effort to increase the profession’s overall technology capacity and become agents to support knowledge workers’ future skill development. letter to the editors information technology and libraries | december 2023 https://doi.org/10.5860/ital.v42i4.16995 about this section letters to the editor reflect the opinions of their authors and are not necessarily those of the ital editorial board or ala’s core division. each letter’s copyright is held by its authors and is published under a creative commons cc-by-nc-4.0 license. dear editorial board, i read richard brzustowicz’s recent article in information technology and libraries, “from chatgpt to catgpt,” and while it excites me to see the conversation about ai and cataloging emerging in the scholarly discourse, i have unfortunately found a number of errors in this article’s methodology which i believe to be incapable of leading in good faith to the conclusions offered. i have included below some supporting evidence, though my comments are not to be taken as a total analysis of this article. in the interest of brevity, my comments will focus primarily on the methodology and conclusions sections of the article, in particular the first comparison of a generated record and one found in worldcat. my feedback is structured in the form of responses to specific quotations from the article that present issues in the domain of cataloging, the evaluation of metadata quality, and the citation of inputs and outputs in interactions with generative ai. “when asked about its training data, chatgpt replied: …” (2) what exactly was asked of chatgpt? without documenting the input, the output lacks sufficient context to draw firm conclusions about its validity. inputs are a critical component of scholarship on ai, as the object of study consists of the input and the output together. for additional context, i have included a brief annotated bibliography of peer reviewed scholarship that cites interactions with chatgpt. choudhary, om prakash, jyoti saini, and amit challana. “chatgpt for veterinary anatomy

libraries december 2023 letter to the editors 2 floyd see section 2.1 (3), “the search prompts provided to chatgpt requested references in the vancouver style, a commonly used citation style in academic writing, along with their corresponding links. we generated the prompt “please provide the references in vancouver style and their links in recent literature on... name of the topic” to chatgpt.” “i asked chatgpt to generate a marc record for the 1996 edition of anne rice’s interview with the vampire using rda (chatgpt, personal communication, february 23, 2023).” (2) the article again does not document the actual input given to chatgpt, therefore the amount of priming chatgpt may have received, or perhaps any ambiguity in the prompt that could explain the composition of the generated record is unknown. for example, consider these three 1996 publications of anne rice’s interview with the vampire that would be recorded on separate bibliographic records. in 1996, knopf published the anniversary edition of the original 1976 ballantine edition; warner books, the uk publisher and distributor, reissued its 1976 edition; and boekerij, in amsterdam, published a translation into dutch with a parallel english title, making it a third 1996 release of anne rice’s interview with the vampire. not all are true editions in the bibliographical sense, but they all were produced in 1996, they all bear the title interview with the vampire, and they all meet the description in the above paraphrase of the prompt given to chatgpt. the prompt also specifies that the record should use rda, however, neither the generated record nor the record offered for comparison actually applies that standard, which goes unacknowledged in the article. if they did, the records would be coded as rda compliant using an 040 field with the element “$e rda.” that is not to say that the records are totally non-compliant with rda though, as there are many similarities between rda and its predecessor ruleset, the anglo american cataloging rules, 2nd edition (aacr2). there are also specifically rda compliant fields in both records, such as the 336, 337, and 338 fields. however, because the record found in worldcat is not coded rda, the most likely source of these fields is an automated process from oclc, as evidenced by the record’s edit history. modifications to records are marked by institution codes added to the 040 field, and the worldcat record selected shows 5 from oclc: “$d oclco $d oclcf $d oclcq $d oclco $d oclca” (9). “i compared it to a record in oclc’s worldcat,” (2) how was this record selected? in worldcat, as accessed through oclc connexion, there are 36 bibliographic records that match the keywords anne, rice, 1996 and the title words interview, vampire. nineteen of these records are cataloged in english. only one is coded rda (oclc record #1300814022), and that record was not the one record selected for comparison. interestingly, it has some errors in its application of rda, such as abbreviating “title page” to “tp.” which is incorrect, and the lack of a relationship indicator for the author (which should be used whenever appropriate, and the “author” relationship here is unambiguous). the record the author selected is oclc #1052676753. it is a good record, without errors, but it does not meet the author’s stated criteria for chatgpt to be compared with, invalidating it as an example. this is also true of the record in table 6. “the results of this test indicate that chatgpt can produce an accurate and effective record for interview with the vampire.” (2) this is incorrect, given the evidence presented. in just this first record, i found the following errors and inconsistencies. in the 100 field, the record uses neither the authorized access point for the information technology and libraries december 2023 letter to the editors 3 floyd author, nor the relationship designator “author” in $e. the authorized access point is “rice, anne, 1941-2021.” the record also has no 250 field (edition). this 1996 copy is a special edition of the book, whether the knopf or the ballantine one, and an edition note is required. the use of a 260 field is incorrect, because only the 264 is able to clearly disambiguate publication information from manufacture, distribution, production, and copyright, as required by rda. in the 300 field, “pages” is abbreviated to “p.,” which, while valid under aacr2, ceased with rda. lastly, and this may just be the formatting of the table, the 650 field’s indicator 0 is in the wrong position. these errors range from relatively minor, to the kind of mistake that would fail a validation check in oclc connexion. further, none of these listed fall into the area of cataloger’s judgment. “as chatgpt follows established cataloging rules, records created by the model are less likely to contain errors or inconsistencies;” (5) the errors present in chatgpt’s generated records directly contradict this claim. “one concern is the potential for copyright infringement, as chatgpt’s detailed descriptions of original works may be too like the originals, leading to legal issues for those who use the generated content without proper attribution or permission. this concern is particularly heightened for copyrighted works like books or music, where even small portions of the work can be protected.” (6) this claim is offered without any supporting citations. the article is not engaging with the discourse about fair use and the copyright status of text used to facilitate search and retrieval, or with specific rulings, such as those in authors guild, inc. v. google, inc. and authors guild, inc. v. hathitrust. “the study demonstrates that chatgpt has the potential to significantly streamline the cataloging process in libraries by generating accurate and consistent records.” (6) i have serious doubts about this conclusion, as can be seen by my above commentary. as a professional and a scholar in the area of cataloging, i find this to be both misleading and underinformative for readers who may someday be tasked with making hard decisions about the value of machine generated metadata vs. the labor of catalogers and metadata specialists. as a result, i would suggest that you seriously consider retraction or significant revisions. david floyd chief cataloging librarian binghamton university dfloyd@binghamton.edu mailto:dfloyd@binghamton.edu lib-mocs-kmc364-20140103102512 64 predicting the need for multiple copies of books robert s. grant, presently at hope college, holland, michigan. an industrial inventory technique adapted to a university library's computer based circulation system as one aid in identifying heavily used books for multiple-copy purchase. the university of windsor has approximately 5,000 students. the university library's open stacks contain more than 300,000 volumes, 100,000 of which are non-circulating (bound periodicals and reference books). there are approximately 200,000 books available for circulation, a booksto-student ratio of 40:1. nevertheless, a perennial student complaint is: "why is it that every time i need a book, someone else has already checked it out?" to help mitigate this problem, the library decided several years ago to embark upon a programme of purchasing multiple copies of much used books. the question then became one of determining which books would need duplicating, and how many more copies of each title would need to be bought. suggestions of titles to be duplicated were at £rst solicited from the faculty, but ever-increasing demands on them prevented their being more than minimally cooperative. three years ago, in an effort to increase the availability of books to undergraduates, the library changed its circulation period for undergraduates from two weeks to one week, with unlimited renewals. at the same time there was instituted a system whereby a student £lied out a reserve card requesting that he be allowed to check out a book upon its predicting need for multiple copies/grant 65 return. when there were five or more such requests, then a copy of the book was to be purchased. although this . system of ordering multiple copies was very cumbersome, it was better than nothing. an article by william l. leffler ( 1) suggested a system of adapting industrial inventory techniques to the problem of identifying books to be duplicated that would be compatible with the library's computer based circulation system and also could be expected to be simpler and more thorough than the above method of buying multiple copies. without rehearsing leffler's arguments, the basic formula used in this project can be simply stated as: n x n9s% nbooks = t where nbook• = the number of copies of a single title necessary to meet at least 95% of student demand for that title; t =number of days of observation, i.e., the number of days in the academic year in which students are permitted to check out books (a constant of 273 in this formula, being the number of days in the period from 1 september to 31 may); n = total number of times a title circulated during t; n9s% =a+ 2s, where a= the average length of time a title was on loan, i.e., the total number of days in which a title was in circulation divided by the number of times (n ) the title circulated. s =standard deviation, which is computed as: j l (a~a) 2 a1 is the length of time, in terms of days, that a single title was off the shelves each time it circulated, and is not to be confused with a which is the average length of time (over the academic year) that the same title was on loan. the sum ( l) of all the a1's was used earlier to calculate a. a1 + a2 + aa . ... etc. a= n for example, if a book circulated three times during the academic year (the first time for 18 days, the second time for 20 days, and the third time for 3 days) then a (the average length of time the book was on loan) would be calculated as 18 + 20 + 3 13 66 3 , or . at this point it should be noted that although the library continues to accept request cards for books presently on loan (and to reserve books for the requestors), these requests are not used as part of the data in determining the number of copies necessary to meet at least 95% of the demand. for one thing, there is no way of knowing how long the person making a request will want to keep a book out, and time is an important element in the formula. but more importantly, the formula, as it now stands, attempts to account for unsatisfied requests. it assumes that in at least some instances there will be more requests for a title than there 66 journal of library automation vol. 4/2 june, 1971 calculate t n '>-----~1 of loans + add 1 t o copies circulati ng n calcu late n o

number of copies of each title the library would need to have in order to more adequately accommodate unsatisfied demand. the programme for performing the calculations is written in pl/1 and is run on an ibm 360 j 50 (figure 1). the execution time for 140,000 circulation records (each time a book circulates the data on its circulation is considered a single record ) is 15 minutes. the historical

to meet present demand. these calculations do not anticipate future demand on the book. also, doubling the number of copies can never succeed in doubling circulation, a fact demonstrated by leimkuhler ( 2). this print-out, therefore, can only serve as one guide to multiple-copy purchase. precautions and pitfalls in using the results of these computations as a guide to the purchase of multiple copies, the librarian should be aware of several factors which may have distorted the results. one is that the student who checks out the only copy of a book and keeps checking it out all year, in lieu of buying his own copy, creates a false "demand" for· the book. it may be that he is the only person in the university interested in it, and when he graduates this book may sit out its life on the shelves completely unused. however, since the historical record file contains the borrower's id number, it is possible to distinguish between an original loan and a renewal. the first time the borrower's id number appears on the book's circulation record indicates the original loan. each additional and consecutive time the same borrower's id number appears on the same circulation record indicates a renewal. although the pilot project did not contain provisions for obviating this problem, it would have been simple enough to build into the programme a mechanism for suppressing the unwanted data. a faculty member who assigns parts of books for students to read, but does not place the books on reserve, forces competition for them on the open shelves. this too creates a demand which may not exist after the professor leaves the university or stops teaching a particular course. the librarian should be aware of such possible short-lived demands that may never recur. the circulation analysis programme was executed at the end of one academic year in order to provide the university of windsor librarians with guidelines for purchase of multiple copies of books to be used in the next academic year. if it were known that a particular book receiving heavy use one year would not receive equally heavy use in the next (because, for example, the particular course requiring that book would no longer be taught; or the book would be placed on a "two-hour reserve" for the coming academic year; or the book circulated frequently in one year only because it was on the "best-seller list"), then it would be folly to purchase three or four additional copies of the book just because the computer print-out indicated that a number of additional copies were 70 journal of library automation vol. 4/2 june, 1971 needed. other factors, therefore, although not included in the input data, are certainly relevant in determining the need for multiple copies. at the university of windsor library, a book that needs to be re-bound because of heavy use or mutilation is charged out to the bindery department. it then shows up on the historical record file, just as though it had been charged out. but since the "borrower's id number" for books charged to the bindery department consists of all zeroes, it would be simple enough to identify and suppress these particular records as unwanted data. by-products in addition to providing a list of books to be considered for duplication, the historical record file upon analysis revealed several other interesting facts about the university library's circulation. most noteworthy is the fact that, although there were more than 200,000 circulating books sitting on the open shelves at the time of this pilot project, only 40,205 different titles circulated for a total of 134,276 times. assuming there were only 100,000 different titles among the 200,000 books, this would mean that nearly 60% of the collection was probably not used by the students. of the 40,205 different works which did circulate, the calculations indicated that only 3,257 titles required one or more copies in order to fill 95% of the requests. of this latter number, only 570 titles were in need of duplication. (that is to say, the number of copies listed under projected need exceeded the number of copies actually owned by the library as indicated by the shelf list.) a random sample comprising one-third of these 570 titles was checked to see whether or not the books were in print. indications were that 38% of the titles in need of duplication were no longer in print. conclusions a close examination of the 570 titles apparently in need of duplication reveals that, with very few exceptions, students are apparently checking out only books that are curriculum oriented in the most narrow sense, i,e., books which they need to use in writing term papers. nevertheless, one can appreciate the fact that these books are in demand by the student, and if the library is to be responsive to users' demands on its facilities, it will need to spend part of the book budget each year purchasing multiple copies of the most heavily used books. unfortunately, even with these good intentions and the sophisticated assistance of the computer, students' demands for books will still be frustrated (at least one-out-of-three times) because books which need to be duplicated are no longer in print.

information technology and libraries | september 2012 36 abstract systems librarians at an academic medical library created a management data dashboard. charts were designed using best practices for data visualization and dashboard layout, and include metrics on gatecount, website visits, instant message reference chats, circulation, and interlibrary loan volume and turnaround time. several charts draw on ezproxy log data that has been analyzed and linked to other databases to reveal use by different academic departments and user roles (such as faculty or student). most charts are bar charts and include a linear regression trend line. the implementation uses perl scripts to retrieve data from eight different sources and add it to a mysql data warehouse, from which php/javascript webpages use google chart tools to create the dashboard charts. introduction new york university health sciences libraries (nyuhsl) had adopted a number of systems that were either open-source, home-grown, or that offered apis of one sort or another. examples include drupal, google analytics, and a home-grown interlibrary loan (ill) system. systems librarians decided to capitalize on the availability of this data by designing a system that would give library management a single, continuously self-updating point of access to monitor a variety of metrics. previously this kind of information had been assembled annually for surveys like aahsl and arl. 1 the layout and scope of the dashboard was influenced by google analytics and a beta dashboard project at brown.2 the dashboard enables closer scrutiny of trends in library use, ideally resulting in a more agile response to problems and opportunities. it allows decisions and trade-offs to be based on concrete data rather than impressions, and it documents the library’s service to its user community, which is important in a challenging budget climate. although the end product builds on a long list of technologies—especially perl, mysql, php, javascript, and google chart tools—the design of the project is lightweight and simple, and the number of lines of code required to power it is remarkably small. further, the design is modular. this means that nyuhsl could offer customized versions for staff in different roles, restricting the display to show only data that is relevant to the individual’s work. because most libraries have a unique combination of technologies in place to handle functions like circulation, reference questions, circulation, and so forth, a one-size-fits-all software package that emily morton-owens (emily.morton.owens@gmail.com) was web services librarian and karen hanson (karen.hanson@med.nyu.edu) is knowledge systems librarian, new york university health sciences libraries, new york. trends at a glance: a management dashboard of library statistics | morton-owens and hanson 37 could be used by any library may not be feasible. instead, this lightweight and modular approach could be re-created relatively easily to fit local circumstances and needs. visual design principles in designing the dashboard, we tried to use some best practices for data visualization and assembling charts into a dashboard. the best-known authority on data visualization, edward tufte, states “above all else, show the data.”3 in part, this means minimizing distractions, such as unnecessary gridlines and playful graphics. ideally, every dot of ink on the page would represent data. he also emphasizes truthful proportions, meaning the chart should be proportional to the actual measurements.4 a chart should display data from zero to the highest quantity, not arbitrarily starting the measurements at a higher number, because that distorts the proportions between the part and the whole. a chart also should not use graphics that differ in width as well as length, because that causes the area of the graphic to increase incorrectly, as opposed to simply the length increasing. pie charts are popular chart types that have serious problems in this respect despite their popularity; they require users to judge the relative area of the slices, which is difficult to do accurately.5 generally, it is better to use a bar chart with different length bars whose proportions users can judge better. color should also be used judiciously. some designers use too many colors for artistic effect, which creates a “visual puzzle”6 as the user wonders whether the colors carry meaning. some colors stand out more than others and should be used with caution. for example, red is often associated with something urgent or negative, so it should only be used in appropriate contexts. duller, less saturated colors are more appropriate for many data visualizations. a contrasting style is exemplified by nigel holmes, who designs charts and infographics with playful visual elements. a recent study compared the participants’ reactions to holmes’ work with plain charts of the same data.7 there was no significant difference in comprehension or shortterm memorability; however, the researchers found that the embellished charts were more memorable over the long term, as well as more enjoyable to look at. that said, holmes’ style is most appropriate for charts that are trying to drive home a certain interpretation. in the case of the dashboard, we did not want to make any specific point, nor did we have any way of knowing in advance what the data would reveal, so we used tufte’s principles in our design. a comparable authority on dashboard design is stephen few. a dashboard combines multiple data displays in a single point of access. as in the most familiar example, a car dashboard, it usually has to do with controlling or monitoring something without taking your focus from the main task.8 a dashboard should be simple and visual, not requiring the user to tune out extraneous information or interpret novel chart concepts. the goal is not to offer a lookup table of precise values. the user should be able to get the idea without reading too much text or having to think information technology and libraries | september 2012 38 too hard about what the graph represents. thinking again of a car, its speedometer does not offer a historical analysis of speed variation because this is too much data to process while the car is moving. similarly, the dashboard should ideally fit on one screen so that it can be taken in at a glance. if this is not possible, at least all of the individual charts should be presented intact, without scrolling or being cramped in ways that distort the data. a dashboard should present data dimensions that are dynamic. the user will refer to the dashboard frequently, so presenting data that does not change over time only takes up space. better yet, the data should be presented alongside a benchmark or goal. a benchmark may be a historical value for the same metric or perhaps a competitor’s value. a goal is an intended future value that may or may not ever have been reached. either way, including this alternate value gives context for whether the current performance is desirable. this is essential for making the dashboard into a decision-making tool. nils rasmussen et al. discuss three levels of dashboards: strategic, tactical (related to progress on a specific project), and operational (related to everyday, department-level processes). 9 so far, nyuhsl’s dashboard is primarily operational, monitoring whether ordinary work is proceeding as planned. later in this paper we will discuss ways to make the dashboard better suited to supporting strategic initiatives. system architecture the dashboard architecture consists of three main parts: importer scripts that get data from diverse sources, a data warehouse, and php/javascript scripts that display the data. the data warehouse is a simple mysql database; the term “warehouse” refers to the fact that it contains a stripped-down, simplified version of the data that is appropriate for analysis rather than operations. our approach to handling the data is an etl (extract, transform, load) routine. data are extracted from different sources, transformed in various ways, and loaded into the data warehouse. our data transformations include reducing granularity and enriching the data using details drawn from other datasets, such as the institutional list of ip ranges and their corresponding departments. data rarely change once in the warehouse because they represent historical measurements, not open transactions.10 there is an importer script customized for each data source. the data sources differ in format and location. for example, google analytics is a remote data source with a unique data export api, the ill data are in a local mysql database, and libraryh3lp has remote csv log files. the scripts run automatically via a cron job at 2a.m. and retrieves data for the previous day. that time was chosen to ensure all other nightly cron jobs that affect the databases are complete before the dashboard imports start. each uses custom code for its data source and creates a series of mysql insert queries to put the needed data fields in the mysql data warehouse. for example, a script might pull the dates when an ill request was placed and filled, but not the title of the requested item. trends at a glance: a management dashboard of library statistics | morton-owens and hanson 39 a carefully thought-out data model simplifies the creation of reports. the data structure should aim to support future expansion. in the data warehouse, information that was previously formatted and stored in very inconsistent ways is brought together uniformly. there is one table for each kind of data with consistent field names for dates, services, and so forth, and others that combine related data in useful ways. the dashboard display consists of a number of widgets, one for each chart. each chart is created with a mixture of php and javascript. google chart tools interprets lines of javascript to draw an attractive, proportional chart. we do not want to hardcode the values in this javascript, of course, because the charts should be dynamic. therefore we use php to query the data warehouse and a statement for each line of results to “write” a line of the data in javascript. figure 1. php is used to read from the database and generate rows of data as server-side javascript. each php/javascript file created through this process is embedded in a master php page. this master page controls the order and layout of the individual widgets using the php include feature to add each chart file to the page plus a css stylesheet to determine the spacing of the charts. finally, because all the queries take a relatively long time to run, the page is cached and refreshes itself the first time the page is opened each day. the dashboard can be refreshed manually if the database or code is modified and someone wants to see the results immediately. many of the dashboard’s charts include a linear regression trend line. this feature is not provided by google charts and must be inserted into the widget’s code manually. the formula can be found online.11 the sums and sums of squares are totted up as the code loops through each line of data, and these totals are used to calculate the slope and intercept. in our twenty-six-week displays, we never want to include the twenty-sixth week of data because that is the present (partial) week. the linear regression line takes the form y = mx + b. we can use that formula along with the slope and intercept values to calculate y-values for week zero and the next-to-last week (week twentyfive). those two points are plotted and the trend line is drawn between them. the color of the line depends on its slope (greater or less than zero). depending on whether we want that chart’s metric to go up or down, the line is green for the desirable direction and red for the undesirable direction. information technology and libraries | september 2012 40 details on individual systems gatecount most of nyuhsl’s five locations have electronic gates to track the number of patrons who visit. formerly these statistics were kept in a microsoft excel spreadsheet, but now there is a simple web form into which staff can enter the gate reading twice daily. the data goes directly into the data warehouse, and the a.m. and p.m. counts are automatically summed. there is some errorchecking to prevent incorrect numbers being entered, which varies depending on whether that location’s gate is the kind that provides a continuously increasing count or is reset each day. the data are presented in a stacked bar chart, summed for the week. the user can hover over the stacked bars to see numbers for each location, but the height of the stacked bar and the trend line represent the total visits for all locations together. figure 2. stacked bar chart with trendline showing visits per week to pphysical library branches over a twenty-six-week period ticketing nyuhsl manages online user requests with a simple ticketing system that integrates with drupal. there are four types of tickets, two of which involve helping users and two of which involve reporting problems. the “helpful” services are general reference questions and literature search requests. the “trouble” services are computer problems and e-resource problems. these two pairs trends at a glance: a management dashboard of library statistics | morton-owens and hanson 41 each have their own stacked bar chart because, ideally, the number of “helpful” tickets would go up while the number of “trouble” tickets would go down. each chart has a trend line, color-coded for the direction that is desirable in that case. figure 3. stacked bar chart with trendline showing trouble tickets by type the script that imports this information into the data warehouse simply does so from another local mysql database. it only fetches the date and the type of request, not the actual question or response. it also inserts a record into the user transactions table, which will be discussed in the section on user data. drupal nyuhsl’s drupal site allows librarians directly to contribute content like subject guides and blog posts.12 the dashboard tracks the number of edits contributed by users (excluding the web services librarian and the web manager, who would otherwise swamp the results). this is done with a simple count query on the node_revisions table in the drupal database. because no other processing is needed and caching ensures the query will be done at most once per day, this is the only widget that pulls data directly from the original database at the time the chart is drawn. koha koha is an open-source opac system. at nyuhsl, koha’s database is in mysql. each night the importer script copies “issues” data from koha’s statistics table. this supports the creation of a information technology and libraries | september 2012 42 stacked bar chart showing the number of item checkouts each week, with each bar divided according to the type of item borrowed (e.g., book or laptop). as with other charts, a color-coded trend line was added to show the change in the number of item checkouts. google analytics the dashboard relies on the google analytics php interface (gapi) to retrieve data using the google analytics data export api.13 nothing is stored in the data warehouse and there is no importer script. the first widget gets and displays weekly total visits for all nyuhsl websites, the main nyuhsl website, and visits from mobile devices. a trend line is calculated from the “all sites” count. the second widget retrieves a list of the top “outbound click” events for the past thirty days and returns them as urls. a regular expression is used to remove any ezproxy prefix, and the remaining url is matched against our electronic resources database to get the title. thus, for example, the widget displays “web of knowledge” instead of “http://ezproxy.med.nyu.edu/login?url=http://apps.isiknowledge.com/.” a future improvement to this display would require a new table in the data warehouse and importer script to store historic outbound click results. this data would support comparison of the current list with past results to identify click destinations that are trending up or down. figure 4. most popular links clicked on to leave the library’s website in a thirty-day period trends at a glance: a management dashboard of library statistics | morton-owens and hanson 43 libraryh3lp libraryh3lp is a jabber-based im product that allows librarians to jointly manage a queue of reference queries. it offers csv-formatted log files that a perl script can access using “curl,” a command-line tool that mimics a web browser’s login, cookies, and file requests. the csv log is downloaded via curl, processed with perl’s text::csv module, and the data are then inserted into the warehouse. the first libraryh3lp widget counts the number of chats handled by each librarian over the past ninety days. the second widget tracks the number of chats for the past twenty-six weeks and includes a trend line. figure 5. bar chart showing number of im chats per week over a twenty-six-week period document delivery services the document delivery services (dds) department fulfills ill requests. the web application that manages these requests is homegrown, with a database in mysql. each night, a script copies the latest requests to the data warehouse. the dashboard uses this data to display a chart of how many requests are made each week and which publications are requested from other libraries most frequently. this data could be used to determine whether there are resources that should be considered for purchase. information technology and libraries | september 2012 44 the dds data was also used to demonstrate how data might be used to track service performance. one chart shows the average time it takes to fulfill a document request. further evaluation is required to determine the usefulness of such a chart for motivating improvement of the service or whether this is perceived as a negative use of the data. some libraries may find this kind of information useful for streamlining services. figure 6. this stacked bar chart shows the number of document delivery requests handled per week. the chart separates patron requests from requests made by other libraries. ezproxy data ezproxy is an oclc tool for authenticating users who attempt to access the library’s electronic resources. it does not log e-resource use where the user is automatically authenticated using the institutional ip range, but the data are still valuable because it logs a significant amount of use that can support in-depth analysis. because of the gaps in the data, much of the analysis looks at patterns and relationships in the data rather than absolute values. karen coombs’ article discussing the analysis of ezproxy logs to understand e-resource at the department level provided the initial motivation to switch on the ezproxy log.14 when logging is enabled, a standard web log file is produced. here is a sample line from the log: 123.45.6.7 amyu0gh5brmuska hansok01 [09/sep/2011:18:25:23 -0500] post http://ovidsp.tx.ovid.com: 80/sp3.3.1a/ovidweb.cgi http/1.1 20020472 http://ovidsp.tx.ovid.com.ezproxy.med.nyu.edu/sp-3.3.1a/ovidweb.cgi trends at a glance: a management dashboard of library statistics | morton-owens and hanson 45 each line in the log contains a user ip address, a unique session id, the user id, the date and time of access, the url requested by the user, the http status code, the number of bytes in the requested file, and the referrer (the page the user clicked on to get to the site). the ezproxy log data undergoes some significant processing before being inserted into the ezproxy report tables. the main goal of this is to enrich the data with relevant supplemental information while eliminating redundancy. to facilitate this process, the importer script first dumps the entire log into a table and then performs multiple updates on the dataset. during the first step of processing, the ip addresses are compared to a list of departmental ip ranges maintained by medical center it. if a match is found, the “location accessed” is stored against the log line. next, the user id is compared with the institutional people database, retrieving a user type (faculty, staff, or student) and a department, if available (e.g., radiology). one item of significant interest to senior management is the level of use within hospitals. as a medical library, we are interested in the library’s value to patient care. if there is significant use in the hospitals, this could furnish positive evidence about the library’s role in the clinical setting. next, the resource url and the referring address are truncated down to domain names. the links in the log are very specific, showing detailed user activity. because the library is operating in a medical environment, privacy is a concern and so specific addresses are truncated to a top-level domain (e.g. ovid.com) to suppress any tie to a specific article, e-book, or other specific resource. finally, a query is run against the remaining raw data to condense the log down to unique session id/resource combinations, and this block of data is inserted into a new table. each user visit to a unique resource in a single session is recorded; for example, if a user visits lexis nexis, ovid medline, scopus, and lexis nexis again in a single session, three lines will be recorded in the user activity table. a single line in the final ezproxy activity table contains a unique combination of location accessed (e.g., tisch hospital), user department (e.g., radiology), user type (e.g., staff), earliest access date/time for that resource (e.g., 9/9/201118:25), resource name (e.g., scopus.com), session id, and referring domain (e.g., hsl.med.nyu.edu). there is significant repetition in the log. depending on what filters are set up, every image within a webpage could be a line in the log. the method of condensing the data described previously results in a much smaller and more manageable dataset. for example, on a single day 115,070 rows of were collected in the ezproxy log, but only 2,198 were inserted into the final warehouse table after truncating the urls and removing redundancy. in a separate query on the raw data table, a distinct list containing user id, date, and the word “eresources” is built and stored in a “user transactions” table. this very basic data are stored so that simple user analysis can be performed (see “user data” below). information technology and libraries | september 2012 46 figure 7. line chart showing total number of ezproxy sessions captured per week over a twenty-sixweek period once the ezproxy data are transferred to the appropriate tables, the raw data (and thus the most concerning data from a privacy standpoint) is purged from the database. several dashboard charts were created using the streamlined ezproxy data, a simple count of weekly e-resource users, and a table showing resources whose use changed most significantly since the previous month. it was challenging to calculate the significance of the variations in use since resources that went from one session in a month to two sessions were showing the same proportional change as those that increased from one thousand to two thousand sessions. a basic calculation was created to highlight the more significant changes in use. d = (pq) if d<0 then significance = d—8 x 10 d q +1 if d>0 then significance = d +8 x 10 d q +1 d = difference between last month and this month p = number of visits last month (8 to 1 days ago) q = number of visits previous month (15 to 9 days ago) trends at a glance: a management dashboard of library statistics | morton-owens and hanson 47 this equation serves the basic purpose of identifying unusual changes in e-resource use. for example, one e-resource was shown trending up in use after a librarian taught a course in it. figure 8. table of e-resources showing the most significant change in use over the last month compared to the previous month the ezproxy data has already proven to be a rich source of data. the work so far has only scratched the surface of what the data could show. only two charts are currently displayed on the dashboard, but the value of thisdata is more likely to come from one-off customized reports based on specific queries, like tracking use of individual resources over time or looking at variations of use within specific buildings, departments, or user types. there is also a lot that could be done with the referrer addresses. for example, the library has been submitting tips to the newsletter that is delivered by email. the referrer log allows the number of clicks from this source to be measured so that librarians can monitor the success of this marketing technique. user data each library system includes some user information. where user information is available in a system, a separate table is populated in the warehouse. as mentioned briefly above, a user id, a date, and the type of service used (e-resources, dds, literature search, etc.) is stored. details of the transaction are not kept here. the user id can be used to look up basic information about the user such as role (faculty, staff, student) and department. we should emphasize for clarity that the detailed information about the activity is completely separated from any information about the user so that the data cannot be joined back together. information technology and libraries | september 2012 48 the most sensitive data, such as the raw ezproxy log data, is purged after the import script has copied the truncated and de-identified data. even though the data stored is very basic, information at the granularity of individual users is never displayed on the dashboard. the user information is aggregated by user type for further analysis and display. the institutional people database can be used to determine how many people are in each department. a table added to the dashboard shows the number of resource uses and the percentage of each department that used library resources in a six-month period. some potential uses of this data include identifying possible training needs and measuring the success of library outreach to specific departments. for example, if one department uses the resources very little, this may indicate a training or marketing deficit. it may also be interesting to analyze how the academic success of a department aligns with library resource use. do the highest intensity users of library resources have greater professional output or higher prestige as a research department, for example? it is unsurprising to find that medical students and librarians are most likely to use library resources. the graduate medical education group is third and includes medical residents (newly qualified doctors on a learning curve). as with the ezproxy data, there are numerous insights to be gained from this data that will help the library make strategic decisions about future services. figure 9. table showing the proportion of each user group that has used at least one library service in a six-month period results trends at a glance: a management dashboard of library statistics | morton-owens and hanson 49 the dashboard has been available for almost a year. it requires a password and is only available to nyuhsl’s senior management team and librarians who have asked for access. feedback on the dashboard has been positive, and librarians have begun to make suggestions to improve its usefulness. one librarian uses the data warehouse for his own reports and will soon provide his queries so that they can be added to the dashboard. the dashboard has facilitated discoveries about the nature of our users and has identified potential training needs and areas of weakness in outreach. a static dashboard snapshot was recently created for presentation to the dean of the medical school to illustrate the extent and breadth of library use. the initial dashboard aimed to demonstrate the kinds of library statistics that it is possible to extract and display, but there is much to be done to improve its operational usefulness. a dashboard working group has been established to build on the original proof-of-concept by improving the data model and adding relevant charts. some charts will be incorporated into the public website as a snapshot of library activity. the dashboard was structured to be adaptable and expandable. the next iteration will support customization of the display for each user. new charts will be added as requested, and charts that are perceived to be less insightful will be removed. for example, one chart shows the number of reference chat requests answered by each librarian in addition to the number of chats handled per week. the usefulness of this chart was questioned when it was observed that the results were merely a reflection of which librarians had the most time at their own desks, allowing them to answer chats. this is an example of how it can be difficult to separate context from numbers. in this instance the individual statistics were only included because the data was available, not because any particular request from management, so these charts may be removed from the dashboard. nyuhsl is also investigating the ex libris tool ustat, which supports analysis of counter (counting online usage of networked electronic resources) reports from e-resources vendors. ustat covers some of the larger gaps in the ezproxy log, including journal-level rather than vendor-level analysis, and most importantly, the use statistics for non-ezproxied addresses. a future project will be to see whether there is an automated way to extract use metrics, either from ustat or directly from the vendors to be incorporated into the data warehouse. preliminary discussion are being held with it administrators about the possibilities of ezproxying library resource urls as they pass through the firewall so that the ezproxy log becomes a more complete reflection of use. an example of a strategic decision based on dashboard data involves nyuhsl’s mobile website. librarians had been considering the question of whether to invest substantial effort in identifying and presenting free apps and mobile websites to complement the library’s small collection of licensed mobile content. the chart of website visits on the dashboard surprisingly shows that the number of visits that come from mobile devices is consistently fewer 3 percent, probably because of the relatively modest selection of mobile-optimized website resources. rather than invest information technology and libraries | september 2012 50 significant effort in cataloging additional potentially lackluster free resources that would not be seen by a large number of users, the team decided to wait for more headlining subscription-based resources to become available and increase traffic to the mobile site. it would be worthwhile to add charts to the dashboard that track metrics related to new strategic initiatives requiring librarians to translate strategic ideas into measurable quantities. for example, if the library aspired to make sure users received responses more quickly, charts tracking the response time for various services could be added and grouped together to track progress on this goal. as data continues to accumulate, it will be possible to extend the timeframe of the charts, for example, making weekly charts into monthly ones. over time, the data may become more static, requiring more complicated calculations to reveal interesting trends. conclusions the medical center has a strong ethic of metric-driven decisions, and the dashboard brings the library in line with this initiative. the dashboard allows librarians and management to monitor key library operations from a single, convenient page, with an emphasis on long-term trends rather than day-to-day fluctuations in use. it was put together using freely available tools that should be within the reach of people with moderate programming experience. assembling the dashboard required background knowledge of the systems in question, was made possible by nyuhsl’s use of open-source and homegrown software, and increased the designers’ understanding of the data and tools in question. references 1 association of academic

data model in the semantic web environment. libraries and various other communities have been using the rdf data model to store valuable data after it is extracted from traditional storage systems. however, because of the large volume of the data, processing and storing it is becoming a nightmare for traditional datamanagement tools. this challenge demands a scalable and distributed system that can manage data in parallel. in this article, a distributed solution is proposed for efficiently processing and storing the large volume of library linked data stored in traditional storage systems. apache spark is used for parallel processing of large data sets and a column-oriented schema is proposed for storing rdf data. the storage system is built on top of hadoop distributed file systems (hdfs) and uses the apache parquet format to store data in a compressed form. the experimental evaluation showed that storage requirements were reduced significantly as compared to jena tdb, sesame, rdf/xml, and n-triples file formats. sparql queries are processed using spark sql to query the compressed data. the experimental evaluation showed a good query response time, which significantly reduces as the number of worker nodes increases. introduction more and more organizations, communities, and research-development centers are using semantic web technologies to represent data using rdf. libraries have been trying to replace the cataloging system using a linked-data technique such as bibframe.1 libraries have received much attention on transitioning marc cataloging data into rdf format.2 data stored in various other formats such as relational databases, csv, and html have already begun their journey toward the open-data movement.3 libraries have participated in the evolution of linked open data (lod) to make data an essential part of the web.4 various researchers have explored areas related to library data and linked data. in particular, transitioning legacy library data into linked data has dominated most of the research works. other areas include researching the impact of linked library data, investigating how privacy and security can be maintained, and exploring the potential effects of having open linked library data. obviously, a linked-data approach for publishing data on the web brings many benefits to libraries. first, once isolated library data currently stored using traditional cataloging systems (marc) becomes a part of the web, it can be shared, reused, and consumed by web users.5 this promotes the cross-domain sharing of knowledge hidden in the library data, opening the library as a rich source of information. online library users can share more information using linked library resources since every library mailto:kumar.asom@gmail.com

crawlable on the web via uniform resource identifiers (uri). most importantly, library data benefits from linked-data technology’s real advantages, such as interoperability, integration with other systems, data crosswalks, and smart federated search.6 numerous approaches have evolved for making the vision of the semantic web a success. no doubt, they have succeeded in making the library a part of the web, but there remain issues related to library big data. the term big data refers to data or information that cannot be processed using traditional software systems.7 the volume of such data is so large that it requires advanced technologies for processing and storing the information. libraries also have real concerns with large volumes of data during and after the transition to linked data. the main challenges are in processing and storage. during conversion from library data to rdf, the process can become stalled because of the large volumes of data. once the data is successfully converted into rdf formats, there are storage issues. finally, even if the data is somehow stored using common rdf triple stores, it is difficult to retrieve and filter. this is a challenging problem that every librarian must give attention to. librarians should know the real nature of library big data, which causes problems in analyzing data and decision making. librarians must also know the technologies that can resolve these issues. the rate of data generation and the complexity of the data itself are constantly increasing. traditional data-management tools are becoming incapable of managing the data. that is why the definition of big data has been characterized by five vs—volume, velocity, variety, value, and veracity.8 • volume is the amount of the data. • velocity is the data-generation rate (which is high in this case). • variety refers to the heterogeneous nature of the data. • value refers to the actual use of the data after the extraction. • veracity is the quality or trustworthiness of the data. to handle the five vs of big data, distributed technologies such as commodity hardware, parallel processing frameworks, and optimized storage systems are needed. commodity hardware reduces the cost of setting up a distributed environment and can be managed with very limited configurations. a parallel processing system can process distributed data in parallel to reduce processing time. an optimized storage system is required to store the large volume of data, supporting scalability to accommodate more data on demand. with these library requirements to tackle the challenges posed by library big data, a distributed solution is proposed. this approach is based on apache hadoop, apache spark, and a column-oriented storage system to process largesize data and to store the processed data in a compressed form. bibliographic rdf data from british national library and the national library of portugal have been used for this experiment. these bibliographic data are processed using apache spark and stored using apache parquet format. the stored data can be queried using sparql queries for which spark sql is used to execute queries. given an existing rdf dataset, we designed a schema for storing rdf data using a columnoriented database. using column-oriented design with apache parquet and spark sql as the query information technology and libraries | september 2018 31 processor, a distributed rdf storage system was implemented that can store any amount of rdf data by increasing the number of distributed nodes as needed. literature review while big data continues to rise, library data are still in traditional storage systems isolated from the web. to continue working with the web, libraries must redesign the way they format data and contribute toward the web of data. to serve library data to other communities, libraries must integrate their data with the web. attempts to do this have been made by several researchers. the task of integration cannot be achieved by only librarians; rather, it requires a team of experts in the field of library and information technology. the advanced way for integrating resources is with linked-data technology by assigning uris to every piece of library data. with this goal, there exist various projects related to the convergence of library data and linked data. one of these, bibframe, is an initiative to transition bibliographic resources into linked-data representation. bibframe aims to replace traditional cataloging standards such as marc and unimarc using the concept of publishing structured data on the web. marc formats cannot be exchanged easily with nonlibrary systems. the marc standard also suffers from inconsistencies, errors, and inability to express relationships between records and fields within the record. that is why mostly bibliographic resources stored in marc standards are targeted for conversion.9 other works include the open-data initiative from the british national library, library catalog to linked opendata conversion, exposing library data as linked data, and building a knowledge graph to reshape the library staff directory.10 linked data is fully dependent on rdf. rdf reveals graph-like structures where resources are linked with one another. thus, rdf can improve on marc standards because of its strong ability to link related resources. this system of revealing everything as a graph helps in building a network of library resources and other data on the web. this also makes for fast search functionality. in addition, searching a topic or book could bring similar graphs from other library resources, leading to the creation of linked-data service.11 such a service has been implemented by the german national library to provide bibliographic and authority data in rdf format, by the europeana linked open data with access to open metadata on millions of books and multimedia data, and by the library of congress linked data service.12 there is less discussion of library big data. though big data in general is in active research, the library domain has received much less attention than the broader concept of big data and its challenges. this could be because most of librarians working with linked data are from nontechnical backgrounds. now is the right time for libraries to give priority to adopting big data technologies to overcome challenges posed by big data. wang et al. have discussed library big data issues and challenges.13 they made some statements about whether library data belongs to the big data category. obviously, library data belongs to big data since it fulfills some of the characteristics of big data, such as volume, variety, and velocity. wang et al. also raise some of libraries’ challenges related to library big data, such as lacking teams of experts, inability to adopt big data due to budgetary issues, and technical challenges. finally, they point out that to take advantage of the web’s full potential, library data must be transformed into a format that can be accessible beyond the library using technologies like semantic web and linked data. the web has already started its work related to big-data challenges. libraries need to transition their data into an advanced format with the ability to handle big-data issues. the main problems efficiently processing and storing library linked data | sharma, marjit, and biswas 32 https://doi.org/10.6017/ital.v37i3.10177 related to library big data happen at data transformation and storage. to store and retrieve large amounts of data, we need commodity hardware that can handle trillions of rdf triples, requiring terabytes or petabytes of disk space. as of now, there are semantic web frameworks such as jena and sesame to handle rdf data, but these frameworks are not scalable for large rdf graphs.14 jena is a java-based framework for building semantic web and linked-data applications. it is basically a semantic web programming framework that provides java libraries for dealing with rdf data. jena tdb is the component of jena for storing and querying rdf data. 15 it is designed to work in a single-node environment. sesame is also a semantic web framework for processing, storing, and querying rdf data. basically, sesame is a web-based architecture for storing and querying rdf data as well as schema information. 16 background this section briefly describes the structure of rdf triples, apache spark along with its features and column-oriented database system, and apache parquet. structure of rdf triples rdf is a schema-less data model. it implies that the data is not fixed to a specific schema, so it does not need to conform to any predefined schema. unlike in relational tables, where we define columns during schema definition and those columns must contain the required type of data, in rdf we can have any number of properties and data using any kind of vocabulary. we only need vocabulary terms to embed properties. the vocabulary is created using domain ontology, which represents the schemas. to describe library resources we need a library-domain ontology. for example, to define a book and its properties one can use the bookont ontology.17 bookont is a book-structure ontology designed for an optimized book search and retrieval process. however, it is not mandatory to use existing ontology and all the properties defined under it. we can use terms from a newly created ontology or mixed ontologies with required properties. rdf represents resources in the form of subject, predicate, and object. the subject is the resource being described, identified by a uri. this subject can have any number of property-value pairs. this way representation of a resource is called knowledge representation, where everything is defined as a knowledge in the form of entity attribute value (eav). in rdf, the basic unit of information is a triple t, such that t = {subject, predicate, object}. such information when stored on disk is called a triplestore. the collection of rdf triples is called an rdf database. an rdf database is specially designed to store linked data to make the web more useful by interlinking data from different sources in a meaningful way. the real advantage of rdf is its support of the common data model. rdf is the standard way for publishing meaningful data on the web, and this is backed by linked data. linked data provides some rules about how data can be published on the web by following the rdf data model.18 with such a common data model, one can integrate data from any sources by inserting new property-value pairs without altering database schema. another important purpose of rdf is to provide resources to be processable by software agents on the web. rdf triples are of two types: literal triples and linked triples. literal triples consist of a uri referenced subject and a literal object (scalar value) joined by a predicate. in linked triples, both the subject and the object consist of uris linking by the predicate. this type of linking is called rdf link, which is the basis for interlinking the resources.19 rdf data are queried using the sparql query language.20 sparql is a graph-matching query language and is used to retrieve information technology and libraries | september 2018 33 triples from the triple store. the sparql queries are also called semantic queries. like sql queries, sparql also finds and retrieves the information stored in the triplestore. a sparql query is composed of five main components:21 • the prefix declaration part is used to abbreviate the uris; • the dataset definition is used to specify the rdf dataset from which the data is to be fetched; • the result clause is used to specify what information is needed to be fetched, which can be select, construct, describe, and ask; • the query pattern is used to specify the search conditions; and • the query modifiers are used to rearrange query results using order by, limit etc. hadoop and mapreduce hadoop is open-source software that supports distributed processing of large datasets on machine clusters.22 two core components—hadoop distributed file system (hdfs) and mapreduce— make distributed storage and computation of processing jobs possible.23 hdfs is the storage component, whereas mapreduce is a distributed data-processing framework, the computational model of hadoop based on java. the mapreduce algorithm consists of two main tasks: map and reduce. the map task takes a set of data as input and produces another set of data with individual components in the form of key/value pairs or tuples. the output of the map task goes to the reduce task, which combines common key/value pairs into a smaller set of tuples. hdfs and mapreduce are based on driver/worker architecture consisting of driver and worker nodes having different roles. an hdfs driver node is called the name-node while the worker node is called the data-node. the name-node is responsible for managing names and data blocks. data blocks are present in the data-nodes. data-nodes are distributed across each machine, responsible for actual data storage. similarly, the mapreduce driver node is called the job-tracker and the worker node is called the task-tracker. job-tracker is responsible for scheduling jobs on task-trackers. task-tracker again is distributed across each machine along with the data-nodes, responsible for processing map and reducing tasks as instructed by the job-tracker. the concept of hadoop implies that the set of data to be processed is broken into smaller forms that can be processed individually and independently. this way, tasks can be assigned to multiple processors to process the data, and eventually it becomes easy to scale data processing over multiple computing nodes. once a mapreduce program is written, the program can be scaled to run over thousands of machines in a cluster. spark and resilient distributed datasets (rdd) apache spark is an in-memory cluster computing platform, which is a faster batch-processing framework than mapreduce. more importantly, it supports in-memory processing of tasks along with data, so querying data is much faster than disk-based engines. the core of spark is the resilient distributed dataset (rdd). rdd is a fundamental data structure of spark that holds a distributed collection of data where data cannot be modified. rather, data modification yields another immutable collection of data (or rdd). this process is called rdd transformation. for example, figure 1 depicts an example of rdd transformation. the distributed processing and efficiently processing and storing library linked data | sharma, marjit, and biswas 34 https://doi.org/10.6017/ital.v37i3.10177 transformation of data is managed by rdd. rdds are fault-tolerant, meaning that the lost data is recoverable using lineage graph of rdds.24 spark constructs a direct acyclic graph (dag) of a sequence of computations that needed to be performed on data. spark has the most powerful computing engine that allows most of the computations in multistage memory. because of this multistage in-memory computation engine, it provides better performance at reading and writing data than the mapreduce paradigm.25 it aims at speed, ease of use, extensibility, and interactive analytics. spark relies on concepts such as rdd, dag, spark context, transformations, and actions. spark context is an execution environment in which rdds and broadcasting variables can be created. spark context is also called the master of a spark application and allows accessing the cluster through a resource manager. data transformation happens in the spark application when the data is loaded from a data-store into rdds and some filter or map functions are performed to produce a new set of rdds. when the set of computations is created, forming a dag, it does not perform any execution; rather, it prepares for execution in the end, like a lazy loading process. some examples of actions are data extraction or collection and getting the count of words. transformations are the sequence of events, and action is the final execution of the underlying logic. figure 1. rdd transformations. the execution model of spark is shown in figure 2. the execution model is based on the driver/worker architecture consisting of the driver and the worker processes. the driver process creates the spark context and schedules tasks based on the available worker nodes. initially, the master process must be started, then creating worker nodes follows. the driver takes the responsibility of converting a user’s application into several tasks. these tasks are distributed among the workers. the executors are the main components of every spark application. executors actually perform data processing, reading and writing data to the external sources and the storage system. the spark manager is responsible for resource allocation and deallocation to the spark job. basically, spark is only a computation model. it is not related to storage of data, which is a different concept. it only helps in computations and data analytics in a distributed manner. for distributed execution, the task is distributed among the connected nodes so that every node can perform tasks at the same time; it performs the desired operation and notifies the master upon completion of the task. information technology and libraries | september 2018 35 figure 2 execution model of spark. in mapreduce, read/write operations happen between disk and memory, making job computation slower than spark. rdds resolve this by allowing fault-tolerant, distributed, in-memory computations. in rdd, the first load of data is read from disk and then a write-to-disk operation may take place depending upon the program. the operations between first read and last write happen in memory. data on rdds are lazily evaluated, i.e., during rdd transformations, data will not take part until any action is called on the final rdd, which triggers the job execution. the chain of rdd transformations creates dependencies between rdds. each dependency has a function for calculating its data and a pointer to its parent rdd. spark divides rdd dependencies into stages and tasks, then it sends them to workers for execution. hence, an rdd does not actually hold the data; rather, it either loads data from disk or from another rdd and performs some actions on the data for producing results. one of the important features of rdd is its fault tolerance, because of which it can retain and recompute any of the unsuccessful partitions due to node failures. rdds have built-in methods for saving data into files. for example, the rdd calls on saveastextfile(), its data are written on the specified text file line by line. there are numerous options for storing data in different formats, such as json, csv, sequence files, and object files. all these file formats can be saved directly into hdfs or normal file systems. spark sql and dataframe spark sql is a query interface for processing structured data using sql style on the distributed collection of data. that means it is used for querying structured data stored in hdfs (like hive) and parquet. spark sql runs on top of spark as a library and provides higher optimization. the efficiently processing and storing library linked data | sharma, marjit, and biswas 36 https://doi.org/10.6017/ital.v37i3.10177 spark dataframe is an api (application programming interface) that can perform relational operations on rdds and external data sources such as hive and parquet. like rdds, a spark dataframe is also a collection of structured records that can be manipulated by spark sql. it evaluates operations lazily to perform relational optimizations.26 a dataframe is created using rdds along with the schema information. for example, the java code snippet below creates a dataframe using rdd and a schema called rdftriple (rdf-triple schema will be discussed in the proposed approach). javardd<string> n_triples_ = marc_records.map(new texttostring()); javardd<rdftriple> rdf_triples = n_triples.map(new linestordffunction()); dataset<row> dataframe = sparksession.createdataframe(rdf_triples, rdftriple.class); dataframe.write().parquet("/full-path/rdfdata.parquet"); the spark dataframe uses memory management wisely by saving data in off-heap memory and provides an optimized execution plan. conceptually, a dataframe is equivalent to the relational tables with richer optimization and supports sql queries over its data. so, a dataframe is used for storing data into tables. structured data from spark dataframe can be saved into the parquet file format as shown in the above code snippet. column-oriented database a database is a persistent collection of records. these records are accessed via queries. the system that stores data and processes queries to retrieve data is called a database system. such systems use indexes or iteration over the records to find the required information stored in the database. indexes are an auxiliary, dictionary-like data structure that keeps indexes of individual records. indexing is efficient in some cases, however, as it requires two lookup operations and it slows down the access time. data scanning or iteration over each record resolves the query by finding the exact location of the records. it is inefficient when the size of the data is too large. as data-generation rate is increasing constantly, more and more data is going to be stored on the disk. for a fast-growing rate of data, we need a system that can adjust to more data than traditional storage systems and, at the same time, query-processing tasks should take less time. when the data gets too large, indexing and record scanning will be costly during querying. hence, a satisfying solution is the columnar-storage system, which stores data by columns rather than by rows. 27 a column-oriented database system stores data in corresponding columns, and each column is stored in a separate file into the disk. this makes data access time much quicker. since each column is stored separately, any required data can directly be accessed instead of reading all the data. that means any column can be used as an index, making it auto-indexing. that is why the column-oriented representation is much faster than the row-oriented representation. apart from this, data is stored in the compressed form. each column is compressed using a different scheme. in the column-oriented database, the compression is always efficient as all the values belong to the same data type. hence, column-oriented databases require less disk space, as they do not need additional storage for indexes since the data is stored within the indexes themselves. consider an example where a database table named “book” consisting of columns “bookid,” “title,” and “price.” following a column-oriented approach, all the values for bookid are stored together under the “bookid” column, all the values for title are stored together under “title” column. and so on as shown in figure 3. information technology and libraries | september 2018 37 figure 3 an example of an entity and its row and column representation. apache parquet parquet is a top-level apache project that stores data in column-oriented fashion, highly compressed and densely packed in the disk.28 it is a self-describing data format that embeds schema within the data itself. it supports efficient compression and encoding schemes that allows lowering data-storage costs and maximizes the effectiveness of querying data. parquet has added advantages, such as limiting the i/o operation and storing data in compressed form using the snappy method developed by google and used in its production environment. hence it is designed especially for space and query efficiency. snappy aims at compressing petabytes of data in minimal amounts of time, and especially aims for resolving big data issues.29 the data compression rate is more than 250 mb/sec, and decompression rate is more than 500 mb/sec. these compression and decompression rates are for a single core of a system having a core i7 processor in 64-bit mode. it is even faster than the fastest mode of zlib compression algorithm.30 parquet is implemented using column-striping and assembly-language algorithms that are optimized for storing large data-blocks.31 it supports nested data structures in which each value of the same column is stored in contiguous memory locations.32 apache parquet is flexible and can work with many programming languages because it is implemented using apache thrift (https://thrift.apache.org/). a parquet file is divided into row groups and metadata at the end of the file. each row group is divided into column values (or column chunks), such as column 1, column 2, and so on as shown in figure 4. each column value is divided into pages, and each page consists of the page header, repetition levels, definition levels, and values. the footer of the file contains various metadata, such as file metadata, column metadata, and page-header metadata. the metadata information is required to locate and find the values, just like indexing. https://thrift.apache.org/ efficiently processing and storing library linked data | sharma, marjit, and biswas 38 https://doi.org/10.6017/ital.v37i3.10177 figure 4 parquet file structure. the proposed approach the proposed approach relies on spark’s core apis—rdd, spark sql, and dataframe—which can operate on large datasets. rdd is used to load the initial data from the input file, process the data and transform them into triple structure. spark dataframe is used to load the data from rdd into the triple structure and send the transformed rdf data into a parquet file. spark sql is used to fetch the data stored in the parquet file. processing rdf data processing rdf data from large rdf/xml files requires breaking the file into smaller file components. general data-processing systems cannot handle large files because they face memory issues. at this stage, the proposed approach can process the data using an n-triples file, hence individual rdf/xml files again need to be converted into the n-triples file format. the process of breaking rdf/xml file into smaller file components and then converting them into n-triples format depends upon the size of the input file. if it is not more than 500 mb then it is directly converted into n-triples file format. multiple rdf/xml files are converted into individual ntriples file formats, which are again combined into one n-triples file, as the proposed spark application reads input from a single file. information technology and libraries | september 2018 39 schema to store rdf data a simple rdf schema with three triple entities has been designed. this schema is an rdf triple view, which is the building block of the rdf storage schema proposed in this work. the rdf triple view is a simple java class consisting of three attributes—subject, predicate, and object. given an rdf dataset d, consisting of a set of rdf triples t, in either rdf/xml or n-triples format, the dataset is transformed into a format that can be processed by a spark application. further, the dataset is transformed into a line-based format where the individual triple statement is placed in a line separated by a new-line (\n) character. a line contains three components—subject, predicate, and object separated by a space. here each line is unique, using the combined information of subject, predicate, and object. given an rdf triple structure ti, ti = (si, pi, oi) and ti ∈ t, for each t an instance of rdf triple view is created to hold the triple information. the columnar schema organizes triple information into three components, storing each component separately as subject, predicate, and object columns (figure 5). figure 5. rdf triple view. rdf storage we store the rdf data based on rdf triple view, which is the main schema for storing data in the triple representation. we do not need any indexing or additional information related to subject, predicate, or object to be stored on the disk. since we can have any number of temporary dataframe tables in memory, join operations can be performed using these tables to filter the data. in the absence of expensive indexing and additional triple information, storage area can be reduced significantly. apart from this, the compression technique used in apache parquet reduces lot more space than storing in other triple stores. in figure 6, we illustrate the data-storing process. efficiently processing and storing library linked data | sharma, marjit, and biswas 40 https://doi.org/10.6017/ital.v37i3.10177 figure 6. data-storing process in hdfs. the collection of triple instances is loaded into an rdd. at the end, the collection of triple instances is loaded into spark dataframe. spark dataframes are equivalent to the rdbms tables and support both structured and unstructured data formats. using a single schema, multiple dataframes can be used and can be registered as temporary tables in the memory, where highlevel sql queries can be executed on top of them. here the concept of using multiple dataframes with a single schema is motivated to avoid joins and indexing. in the final step, the spark dataframe is saved into hdfs files in the parquet format. from the parquet file, the data can be loaded back into dataframes in memory and queried using spark sql. fetching data from storage given an rdf dataset d, a sparql query q, and a columnar-schema s, we use s to translate q to q' to perform queries on top of s. here, the answer of query q' on top of s is equal to the answer of q on top of d. query mappings m are used to transform sparql queries into spark sql queries. for querying, first the data is loaded into a spark dataframe from parquet files. to query data using sparql, queries must follow basic graph patterns (bgp). a bgp is a set of triple patterns similar to an rdf triple (s, p, o) where any of s, p, and o can be query variables or literals. bgp is used for matching a triple pattern to an rdf graph. this process is called binding between query variables and rdf terms. the statements listed under the where clause is known as bgp consisting of query patterns. for example, the query “select ?name ?mbox where {?x foaf:name ?name . ?x foaf:mbox ?mbox .}” has two query patterns. to evaluate the query containing two query patterns, one join is required. based on the total number of query patterns, information technology and libraries | september 2018 41 we need one less number of joins. that is, for n number of query patterns we need n-1 joins to resolve the values. figure 7 illustrates the process of query execution. figure 7. process of query execution. evaluation to evaluate the proposed approach we compare the storage size with file-based storage systems such as n-triples files and rdf/xml files. we also compare with standard triple stores such as jena tdb and sesame. the data-storing time is compared with jena tdb, sesame, and parquet, having one, two, and three worker nodes respectively. finally, for the purposes of the experiment, some sparql queries are selected and tested over rdf data stored in parquet format into hdfs. the query performance is tested on the distributed system having one, two, and three worker nodes respectively. in the following subsections, we show the results for each of the above comparisons. datasets for evaluation, we use two datasets. dataset 1 contains bibliographic data from the national library of portugal (nlp) (http://opendata.bnportugal.pt/eng_linked_data.htm). from nlp, we choose the nlp catalogue datasets in rdf/xml formats. the datasets are freely available to reuse and contain metadata information from nlp catalogue, the national bibliographic database, the portuguese national bibliography, and the national digital library. the datasets are available as linked data, which were produced in the context of the european library. the size of the rdf/xml file is 6.46 gb with more than 45 billion rdf triples. http://opendata.bnportugal.pt/eng_linked_data.htm efficiently processing and storing library linked data | sharma, marjit, and biswas 42 https://doi.org/10.6017/ital.v37i3.10177 dataset 2 contains bibliographic data from the british national library (https://www.bl.uk/bibliographic/download.html). from the british national bibliography collection we choose the bnb lod books dataset. the datasets are publicly available and contain bibliographic records of different categories, such as books, locations, bibliographic resources, persons, organizations, and agents. the datasets are divided into sixty-seven files in rdf format. however, we combine them into one file in n-triples format to fit the requirement of the large size of the input data. the combined file is 22.52 gb and contains more than 16 billion rdf resources in n-triples format, making it suitable for the proposed approach. from this conversion, we get more than 150 billion rdf triples. figure 8. data storage time for different file formats. figure 9. disk size for different file formats. disk storage figure 8 shows the data-storing time using sesame, jena tdb, and parquet for the above two datasets. data from raw rdf files are stored in jena tdb and sesame. individual files are processed for storing into jena tdb and sesame to avoid memory overflow as jena or sesame models cannot load data at once from the large files. to store data in parquet format we run the program separately on different worker nodes. figure 9 presents the total disk size required for each of these file formats and triple stores for the two datasets. https://www.bl.uk/bibliographic/download.html information technology and libraries | september 2018 43 query performance for testing, the sparql queries are converted manually at this stage. we run some of the selected queries over bibliographic rdf data stored in parquet file format in hdfs. we run the following type of queries on worker nodes 1, 2 and 3 respectively. the queries are listed below: q1) the first query is to fetch the count of rdf triples present in the storage. query: select (count(*) as ?count) where ?s ?p ?o . q2) the second query is to fetch the entire dataset in spo format. it fetches data in the n triples format. query: select * { ?s ?p ?o } . q3) the third query is to fetch resources that belong to books with the subject “english language composition and exercises.” query: select ?s where ?x rdf:type bibo:book . ?x dc:subject <http://bnb.data.bl.uk/id/concept/lcsh/english_language_composition_and_exercises> . q4) the fourth query is to fetch resources that belong to books with the subject “english language composition and exercises” and creator “palmer frederick.” query: select ?s where ?x rdf:type bibo:book . ?x dc:subject <http://bnb.data.bl.uk/id/concept/lcsh/english_language_composition_and_exercises> . ?x dc:creator <http://bnb.data.bl.uk/id/person/palmer_frederick>. q5) the fifth query is to fetch objects having predicate dcterms:ispartof. query: select ?name where ?s dcterms:ispartof ?name . figure 10 shows the query response time for the above queries on different worker nodes for two different datasets. the queries are executed in the distributed environment. it shows that increasing the number of worker nodes decreases the query response time. efficiently processing and storing

response time, the proposed approach is tested with the first dataset as mentioned above. though at this stage the proposed approach requires further research to be compared with other distributed triple storage systems. also, it requires more worker nodes and larger datasets compatible for parallel processing in the distributed environment. with a smaller setup, it will be hard to analyze the performance of the individual approaches, as they may produce similar results. we compare the proposed approach with the standard jena tdb solution in a single-node environment. the following sparql queries are tested against dataset 1. prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> prefix dc: <http://purl.org/dc/terms/> prefix rdau: <http://rdaregistry.info/elements/u/> prefix foaf:

time with the above queries. first, we test with jena tdb. we then test the proposed approach on a single-node environment. we execute the above set of queries multiple times to record the average performance. as mentioned above, no indexing is used in the storage. rdf triples are stored as they appeared in the n-triples file. queries are executed without indexing and are still getting better performance than jena tdb, as shown in figure 11. discussion in this article, we claim that apache spark and column-oriented databases can resolve library big data issues. especially when dealing with rdf data, spark can perform far better than other approaches because of its in-memory processing ability. concerning rdf data storage, the column-oriented database is suitable for storing the large volume of data because of its scalability, fast data loading, and highly efficient data compression and partitioning. a column-oriented database system requires less disk, reducing the storage area. as a proof, we have shown the data storage comparison and the performance of the columnar-storage for rdf data using parquet formats in hdfs. as shown in the results, apache parquet takes much less disk space as compared to other storage systems. also, the data-storing time is relatively very small as compared to others. we observed that the result of query 2 is the entire dataset stored in parquet format. the size of this resultant dataset is 22.52 gb, which is the same as the original size. the same dataset when stored with parquet format is reduced to 2.89 gb. this shows that parquet is a very optimized efficiently processing and storing library linked data | sharma, marjit, and biswas 46 https://doi.org/10.6017/ital.v37i3.10177 storage system that can reduce the storage cost. we have shown the query response time for five different sparql queries on distributed nodes for two different datasets. we believe with better schema for storing rdf triples the proposed approach can be improved, and with the used technologies a fast and reliable triple store can be designed. conclusion and future work librarians all over the globe should give priority to integrating library data with the web to enable cross-domain sharing of library data. to do this, they must pay attention to current trends in big data technologies. because the data-generation rate is increasing in every domain, traditional data processing and storage systems are becoming ineffective because of the scale and complexity of the data. in this article, we present a distributed solution for processing and storing a large volume of library linked data. from the experiment, we observe that the processing of large volume of the data takes significantly less time using the proposed approach. also, the storage area is reduced significantly as compared to other storage systems. in the future we plan to optimize the current approach using advanced technologies such as graphx, machine learning tools, and other big -data technologies for even faster data processing, searching, and analyzing. references 1 eric miller et al., “bibliographic framework as a web of data: linked data model and supporting

datasets disk storage query performance query comparison discussion conclusion and future work references automated periodicals system at a community college library vivian harp: staff analyst, illinois bell telephone company, chicago, and gertrude heard: serials technician, moraine valley community college library, palos hills, illinois. at the time of writing, ms. harp was assistant librarian at the moraine valley community college library. 83 automated systems need not be extensive to save time and improve efficiency. moraine valley's off-line operation, based on a file of 715 periodical titles, generates renewal orders, sends claims, and records subscription histories. background moraine valley community college (mvcc) is a two-year institution serving southwest cook county, illinois. it opened in september 1968 and now has an enrollment of 3,468 students. the library maintains 715 paid and free periodical subscriptions. because of the small staff size, periodicals had originally been handled by the cataloger. two subscription agencies were tried and found unsatisfactory. problems with overlapping subscriptions and lapsed subscriptions which were never picked up became quite severe, and time spent tracking down problems approached that needed to handle orders and renewals independently. periodicals were transferred to the public service librarian when the staff was expanded. as untangling of agency problems proved more and more time-consuming, a serials technician was assigned to maintain subscriptions, straighten out old problems, check in periodicals, and handle claims. for each subscription, bibliographic and order information and mvcc holdings were entered on a three-by-five-inch history card; on the verso were records for each renewal of purchase order number, subscription length, cost, and subscription dates. magazines were and are checked in on kardex files; the kardex card also holds the latest publisher's mailing label. a checklist is used to ensure that eaqh new title has a kardex card and storage box prepared and a listing in the public holdings record, plus any special instructions for routing. form letters are used for original enquiries to the publisher regarding availability and cost. when a subscription was renewed, data from the "current'' section of 84 journal of library automation vol. 7/2 june 1974 the history cards had to be transferred to the back and updated information entered on the front. a worksheet was made up to give all the necessary renewal information to the typist and the actual purchase order typed from that worksheet. once the purchase order was completed its number was marked on the worksheet and the history card. worksheets were kept on file to serve as easily accessible copies of the purchase orders for use in correspondence since the library copy of the purchase order was tied up in the accounting process. since many publishers do not provide renewal notification-and in our case these renewals amounted to over 40 percent of our orders-various methods to provide ourselves with notification of approaching expirations were attempted, including the use of colored plastic jackets in the history card file and division of the file by date. failure in this area was the chief weakness of the manual system. the cards were bulky and required much handling. creating a holdings list destroyed any semblance of the colorcoded order. if a card were removed for use in correspondence, it could be misplaced or misfiled and therefore not be considered for renewal at the proper time. duplication of paperwork and repeated erasures and transfers of information on the cards were other drawbacks of this operation. introduction to automated system it was hoped that an automated system would indicate approaching expirations and simplify the actual renewal procedure. the following specific objectives were set up: 1. to provide advance notice of subscriptions due for renewal even if a renewal notice were not received. 2. to produce a purchase order, or a replica providing on a single sheet all data needed for renewal. 3. to produce a list of periodical holdings that included the history of all renewals. 4. to claim missing issues of paid and free subscriptions. 5. to produce fiscal and subject area cost reports that would facilitate budget evaluation. two special problems had to be given consideration: ( 1) the college has a complicated check approval system requiring initiation of purchase orders two months before the check is needed; and ( 2) the automated system needed the capability to handle standing orders, government documents (depository and agency items), free materials, and titles held only on microfilm as well as ordinary renewals. these special items make up almost 30 percent of the total subscriptions, and to maintain a parallel manual system for them would be unsatisfactory. method and materials selecting

be wasted effort, but as a by-product of the master file we wanted to generate public holdings lists twice a year. necessary data were readily available from the three-by-five-inch cards, with one addition-a unique number was assigned to each title. the data necessary would require more than one input card to produce the type of reports we wanted; therefore, as data elements were being considered, card codes and item numbers were also assigned to identify information for programming purposes. space was allocated to each field, using information recorded on the history cards, and the coding of certain fixed and variable fields was decided upon. the card formats are outlined in figure 1. figures 2 and 2a list the codes and their meanings. all cards-column1-5 unique number 6 card

9. send all updates to information systems at least three days before the master list and facsimiles are due to be run. price changes do occur between the time the item is flagged and the check is mailed. with most, though, notification is received from the publisher before the purchase order is actually typed, and corrections are made at that time. since the renewal process is linked to the expiration field, updating that field also causes transfer of data for the year just expired into the history record, as explained earlier. free materials, government depository items, and standing orders for which invoicing is known to be automatic are handled by filling the expiration date field with zeros. if a purchase order history record is needed, as with standing orders, these fields are updated at the time the invoice arrives. our master list does not contain headings to explain field descriptions. we place our master list in· a binder; a legend describing placement of field descriptions is attached to the inside of the front of the binder cover and is readily available for reference. we felt headings on each record would be clumsy, confusing, and would waste valuable printing space. codes and their explanations are attached to the inside of the back of the binder cover. to date, two revisions have been installed into the system: ( 1) in 1972 we decided to classify our holdings by subject. space was "found" for three digits, and we then proceeded to code our subjects (figure 3, item 027). our subject codes and their meanings are explained in figure 2a. ( 2) correspondence was assisted by having all necessary information in one location. the cost, purchase order number, and problem explanation were available by merely flipping the printout pages to the title in question on the master list. however, the date the purchase order was typed had to be looked up in order to effect an intelligent solution. six spaces were again "found" to provide this purchase order date (figure 3, item 028). actual computer programming was performed by information systems staff in bal, and programs are run on the college ibm 370-135 computer. automated pet·iodicals system/harp and heard 95 results it has not been possible to figure actual monetary costs for the library portion and maintenance of this system, nor to compare these costs with the manual system. libraries have traditionally been weak in figuring operation costs, and we confess to not having been very innovative in this area. we do not have specific itemized costs for our manual routines, so actual comparisons are not possible. a few figures concerning library time can be given. from october through december of 1971, when the initial phase was set up, the serials technician and public services librarian each contributed about 20 percent of their time, and a student aide worked 10 to 15 hours per week on the clerical part of the data transmittal. since that time the system has been operational for over two years, and some time approximations concerning updating, adding to the file, etc., are now available. with development behind us, time contributed by the serials technician, who is now solely responsible for the maintenance of the system, has dropped from 20 percent to between 5 and 15 percent. exact costs are difficult to extract, since this varies during the year according to the number of renewals due in particularly heavy expiration months as compared with those due in light expiration months. the library as part of the college is not charged for use of computer facilities. figures for machine time and keypunching are available and are as follows: program periodical additions per 100 titles periodical updates per 100 titles purchase order printing claim disbursements miscellaneous reports machine time (hr.) .1 .1 .5 .1 3.0 keypunch time (hr.) 8.0 2.0 .5 .2 .0 information systems has given their monetary cost in developing this system as $5,970 for programming time. they also figure program maintenance at $215 per year and the cost to run programs per year at $256. we can list important benefits we have derived. renewal problems have been eliminated. the few duplicate problems can be handled now as soon as they occur. our system handles all types of live subscriptions and the "dead file" as well. there is no more fussing with cards since we have a one-stop, clear record of holdings and histories, including the entire invoice and payment record for each subscription. at renewal time all the information for purchase orders is listed on a single-sheet facsimile. claim letters are done for us and we can call for various listings as they are needed. reports we receive are: master listing once a month, purchase order facsimiles once a month, claim letters as needed, fiscal year total cost re96 journal of library automation vol. 7/2 june 1974 ports, fiscal year area cost reports, subject lists as needed, holdings lists as needed, unique number lists as needed. conclusions many librarians having access to sophisticated computer facilities content themselves with producing a more or less elaborate holdings list. subscription placements and renewals are handled manually, often through a commercial agency. common agency problems such as overlapping and lapsed subscriptions are simply tolerated. we feel from our experience that if enough effort is expended to create a successfully operating holdings list, a small library does not require much further effort to add renewal, history record, and claiming functions. this eliminates agency problems, provides the ability to manipulate files for producing various reports, ancl in our opinion, results in more efficient and convenient record-keeping. the size of our operation falls at the lower end of a range of libraries having holdings large enough to require at least one individual's time. translated into figures, we feel that any automated system would be wasted on holdings of under 150 periodicals. the crucial factor in relation to size is not really any magic number of holdings but the ratio of available staff time to the size of the holdings. this factor must be evaluated by libraries considering any type of automated system. we feel much of the success of our system has been dependent upon our initial planning, our staff availability, and our conviction that a change was necessary to/eliminate the problems we were encountering with our n:ianual system. also the availability of the computer facilities, the encouragement provided by our superiors, and adequate library staff and information systems staff all contributed to an efficient changeover. acknowledgments gratitude is due moraine valley community college for its permission and support of this innovation. particular gratitude is due anabel sproat, head librarian, for her permission, support, and constant encouragement. the excellent work and friendly attitude of linda nemeth and the entire information systems staff who made this project a reality have been ~eeply appreciated. also, the capable assistance of student aide barbara hart ( goeske) in the recording process proved to be a very valuable asset. algorithmic literacy and the role for libraries article algorithmic literacy and the role for libraries michael ridley and danica pawlick-potts information technology and libraries | june 2021 https://doi.org/10.6017/ital.v40i2.12963 abstract artificial intelligence (ai) is powerful, complex, ubiquitous, often opaque, sometimes invisible, and increasingly consequential in our everyday lives. navigating the effects of ai as well as utilizing it in a responsible way requires a level of awareness, understanding, and skill that is not provided by current digital literacy or information literacy regimes. algorithmic literacy addresses these gaps. in arguing for a role for libraries in algorithmic literacy, the authors provide a working definition, a pressing need, a pedagogical strategy, and two specific contributions that are unique to libraries. introduction algorithms, in one form or another, are as old as human problem solving and as simple as “a sequence of computational steps that transform the input into the output.”1 for centuries they have been effective, and uncontroversial, methodologies. however, the rise of artificial intelligence (the integration of big data, enhanced computation, and advanced algorithms) with its human and greater-than-human performance in many areas has positioned algorithms as transformational and a “major human rights issue in the twenty-first century.”2 algorithmic literacy is important given of the prevalence of algorithmic decision-making in many aspects of everyday life and because “the danger is not so much in delegating cognitive tasks, but in distancing ourselves from—or in not knowing about—the nature and precise mechanisms of that delegation.”3 as a result, david lankes warns of a new type of digital divide with “a class of people who can use algorithms and a class used by algorithms.”4 in a 2019 deloitte survey “only 4 percent reported they were confident explaining what ai is and how it works.”5 while a 2019 edelman survey indicated general awareness of ai, it also revealed a similar lack of knowledge about the details of ai.6 an informed, algorithmically literate public is better able to negotiate and employ the complexities of ai.7 identifying and acting upon algorithms as a literacy makes them as “fundamental as reading, writing, and arithmetic.”8 however, the uncritical use of the term literacy should make one suspicious of extending it to algorithms. increasingly “literacy” has come to mean merely a body of knowledge or a set of domain-specific skills.9 various literacies have been described, such as health, death, financial, physical, ocean, religious, visual, dancing, spatial, screen, and porn. this includes a dozen different technology-related literacies.10 the case for algorithmic literacy, and the role for libraries in advancing it, must rest on a clear definition, a recognized problem and need, a pedagogical strategy, and a unique (or at least supportive) contribution libraries can provide. michael ridley (mridley@uoguelph.ca) is librarian emeritus, mclaughlin library, university of guelph, ontario,

information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 2 algorithms and literacy while the term “algorithmic literacy” is recent, it has antecedents that cover similar if not equivalent ground. the general terms computer literacy or digital literacy have spawned more specific terms such as cyber literacy, computational thinking, and algorithmic thinking.11 most of these arise from the field of computer science, where algorithms are central, and focus on the computational nature of algorithms as a “matter of mathematical proof” where “other knowledge about algorithms—such as their applications, effects, and circulation—is strictly out of frame.”12 the implications of algorithms in everyday life suggests that a deeper and broader interpretation is required. whether a literacy, a mode of thinking, or merely a set of skills, discussions about computation and algorithms have been plagued by “ambiguity and vagueness” and “definitional confusion” resulting in ongoing challenges in establishing core pedagogy in both k–12 and higher education.13 without a clear, acknowledged, and actionable definition that differentiates it from concepts such as digital literacy, computational thinking, and algorithmic thinking, algorithmic literacy will be relegated to a buzz phrase and the urgency of its recognition and application will be lost. the relationship between algorithms and artificial intelligence might recommend the adoption of “ai thinking” or “ai literacy” as the more appropriate term.14 however, algorithmic literacy is both more foundational than the broader concept of ai and more actionable than just thinking. algorithms are not a technology like ai or, more generally, computers. algorithms provide a structure that frames—and constrains—how we express ourselves. they are a way of seeing and acting in the world and “need to be understood as relational, contingent, [and] contextual.”15 while the technical and operational aspects of algorithms are important to understand and use (as they are for the technologies and processes of reading and writing in a new language), they are complemented by a broader awareness: literacy is not a set of generic skills or something we do or do not possess, it’s a sociocultural practice, it’s something that we do, and what we do with literacy depends on the social, cultural, and historical contexts in which we do it. literacy looks different in different contexts and communities. literacy is not neutral, it’s ideological. there are dominant and marginalized literacies.16 this perspective is the essence of critical algorithm studies, where algorithms are viewed as sociotechnical systems that are “intrinsically cultural . . . constituted not only by rational procedures, but by institutions, people, intersecting contexts, and the rough-and-ready sensemaking that obtains in ordinary cultural life.”17 algorithms as part of increasingly ubiquitous ai, such as machine learning and deep learning systems, reflect and promulgate certain ideologies and have impacts and influences in the full range of human society. cautions about algorithmic decision-making have identified the far-reaching implications for bias, fairness, privacy, and democratic processes.18 at the same time, numerous national strategies to support ai development have highlighted the substantial economic impact, anticipated to be $15.7 trillion (us) by 2030.19 the idea of algorithmic literacy must encompass multiple perspectives and contexts. information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 3 “literacies of the digital” computer, internet, information, computation, and algorithmic are all “literacies of the digital.” 20 while each of these has its own domain and focus, they share common ideas and are generally symbiotic with each other. there is an especially strong and complementary connection between computational literacy and information literacy.21 computational thinking and algorithmic literacy are closely related even if most definitions of the former fail to fully acknowledge the broader social, economic, and political implications. however, the extensive literature on computational thinking is useful in helping to articulate aspects of algorithmic literacy. wing’s foundational article about computational thinking describes the key characteristics in terms that closely resemble a literacy: 1. conceptualizing, not programming 2. fundamental, not a rote skill 3. a way that humans, not computers, think 4. complements and combines mathematical and engineering thinking 5. ideas, not artifacts 6. for everyone, everywhere.22 jacob and warschauer make a strong case for computational thinking as a literacy. their threepart framework identifies computational thinking as a new literacy embedded in modern sociocultural practices (computational thinking as literacy), discusses how literacy development can be leveraged to foster computational thinking (computational thinking through literacy), and explores ways in which computational thinking can facilitate literacy development (literacy through computational thinking).23 this analysis of computational thinking informs the larger context and broader implications of algorithmic literacy. defining algorithmic literacy scribner and cole define a literacy as “socially organized practices [that] make use of a symbol system and a technology for producing and disseminating it.”24 therefore, literacy = practices + symbol system + technology. to this definition, steiner adds a more aspirational and humanistic definition: by “literacy” i mean the ability to engage with, to respond to, what is most challenging and creative in our societies. to experience and contribute to the energies of informed debate. to distinguish the “news that stays news,” as ezra pound put it, from the tidal waves of ephemeral rubbish, superstition, irrationalism, and commercial exploitation.25 literacy is about knowing and meaning making through the processes of internalizing and externalizing information. literacy enables a reflective, critical, and integrative approach to information that utilizes a broad knowledge base for both understanding and communicatin g ideas. finn calls for an algorithmic literacy “that builds from a basic understanding of computational systems, their potential and their limitations, to offer us intellectual tools for interpreting the algorithms shaping and producing knowledge” and thereby provides “a way to information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 4 contend with both the inherent complexity of computation and the ambiguity that ensues when that complexity intersects with human culture.”26 referring more broadly to “ai literacy,” long and magerko provide an operational view defining it as “a set of competencies that enables individuals to critically evaluate ai technologies; communicate and collaborate effectively with ai; and use ai as a tool online, at home, and in the workplace.” 27 following an exhaustive analysis of different, and often contradictory, definitions of literacy, information literacy, and digital literacy, bawden suggests “explaining, rather than defining, terms.”28 this provisional description of algorithmic literacy acknowledges that advice. algorithmic literacy is the skill, expertise, and awareness to • understand and reason about algorithms and their processes • recognize and interpret their use in systems (whether embedded or overt) • create and apply algorithmic techniques and tools to problems in a variety of do mains • assess the influence and effect of algorithms in social, cultural, economic, and political contexts • position the individual as a co-constituent in algorithmic decision-making. this description recognizes two overarching concepts: “creativity and critical analysis.”29 creativity involves building, creating, and using algorithms for specific purposes. critical analysis involves recognizing the application of algorithms in decision-making and the implications of their use in a variety of settings and within certain contexts. why algorithmic literacy? the need for algorithmic literacy arises from two key and equally important perspectives, both of which essentially focus on power: control and empowerment. algorithms, especially those us ing machine learning and deep learning, are complex, opaque, invisible, shielded by intellectual property protection, and most importantly, consequential in the everyday lives of people.30 control is held by those who build and deploy algorithms, not those who use them. in part because of these characteristics, people hold significant misconceptions about algorithms, their use, and their effect. in a 2019 global survey of consumers, 72% said they understood what ai was. however, despite ai being used in a wide variety of consumer-facing applications (e.g., email, search, social media), 64% said they had never used ai.31 a study of facebook users found that 62% were unaware that the news feed is algorithmically constructed and, even when told this, 12% concluded that it is, as a result, completely random.32 bias, discrimination, and unfairness in ai have been well documented.33 it is clear that poor data combined with underspecified algorithms and uncritical interpretations of the ai model outcomes can lead to abuses in a variety of ways. there is no quick fix, no automated solution to these problems. accordingly, those creating algorithms and those using them must be able to question the source of training data, the strengths and weaknesses of learning algorithms, the metrics for success, and how (and for whom) the systems are being optimized. the overarching objectives are accountability and transparency. perhaps most critically, the prevalence of algorithms in our lives has changed the way we interact with and use those systems, and the ways we behave in personal and social contexts. we conduct information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 5 ourselves to be “algorithmically recognizable” allowing us to become “increasingly legible to machines for capture and calculation.”34 the danger is that this will “lead users to internalize their [algorithm’s] norms and priorities.”35 at the same time the power of algorithmic technology is abused and misused, it remains a powerful technology to enhance human capabilities and insight. algorithms are attributable to dramatic advances in health care and science as well as more mundane (but appreciated) applications such as spam filters. anti-science sentiments, typified by anti-vaxxers, should not be allowed to undermine the opportunities for algorithms that materially improve the human condition and the natural world. those opportunities now extend beyond the well-funded, technology-rich research and corporate ai departments. increasingly more consumer-friendly tools and applications allow a broader and more diverse population to create algorithmic solutions. the rise of mlaas (machine learning as a service) brings together powerful cloud-based machine learning environments with accessible toolsets.36 algorithmic literacy is needed to acknowledge both the technology’s power (control) over people and power (empowerment) for people. recognizing the need for protection and encouragement, many governments have enacted protective legislation and training initiatives. emblematic of the former is the general data protection regulation (gdpr) of the european union with its “right to explanation” for algorithmic decisions.37 exemplary of the latter is finland’s initiative to educate a large portion of their population through “elements of ai,” a free online course.38 despite these advances there remain power imbalances that require vigilance on the part of 21 st century digital citizens. understanding the power and politics of algorithms recognizes their ontological impact in “new ways of ordering the world.”39 effects this profound suggest a deeper and more comprehensive understanding of algorithms is needed: efforts to help people understand algorithms need to continue moving away from a focus on building awareness of algorithms—people increasingly know about “those things called algorithms”—and toward explaining algorithms in such a way that people have a more consistent conceptualization of what algorithms are, what algorithms do, and—what often is overlooked—what algorithms cannot do.40 algorithmic literacy, like all literacies, is not about mastery but levels of competence appropriate to age, circumstance, and need. understood simply as recipes or visual decision trees, algorithms are accessible to even those with minimal digital literacy. public institutions, and specifically libraries, can and must take a lead role in addressing the challenges of this “new world.” the library role in algorithmic literacy libraries have traditionally played a central role in making emerging technologies accessible to their communities whether those be online systems, makerspaces, interactive media, virtual reality, or a host of others. advancing digital access, digital literacy, and digital inclusion have long been the acknowledged by governments and public agencies as a role of the public library even if not appropriately funded to do so.41 recently, libraries have begun addressing their role in relation to ai and algorithmic literacy. information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 6 the urban libraries council (ulc) conducted an informal poll about ai and public libraries.42 of the responding libraries (83 of its 150-member library systems), 45% identified ai as important to their leadership with 23% having a staff person dedicated to ai and 27% providing programming to help the public learn about ai. in response to a question of how best libraries could serve their community in this area, 79% said by framing and building awareness of ai, 68% recommended providing continuous education opportunities for the public, and 61% supported the provision of experiential programming. in 2019, the ulc formed a working group to advance the public library role in ai awareness, education, and experiences. in 2018 the canadian federation of library associations (cfla) held a national forum in part focused on artificial intelligence.43 participant discussions yielded three key priorities with respect to ai: training for library staff, educational materials of for the public, and advocacy initiatives regarding privacy, bias, and transparency. a fourth priority was the inclusion o f ai literacy and awareness in mis and mlis curricula to facilitate a leadership role for the profession in this area. algorithmic literacy programs have two general audiences: members of the community the library serves and the staff of the libraries themselves. for the community, these programs center on awareness and implications, skill development, and application and use.44 through workshops, hands-on laboratories and makerspaces, consumer checklists, and a variety of informational tools, libraries can provide, or partner in providing, resources in an ageand context-appropriate setting. for library staff, an additional focus is required on advocacy with respect to regulatory issues, system development, and the evolution of the local and national information infrastructures. library staff can lead, and participate in, advocacy programs that seek to influence government, public agencies, commercial system and service providers, and others about algorithmic literacy. it is a misconception to think of algorithms, and ai more generally, as arcane topics beyond the ability of library staff to understand and teach. while the technical details of ai are complex, this is not the level of understanding required of staff or needed by the library’s community. for example, ai programing at the frisco public library introduced ai maker kits and ran basic ai classes. the toronto public library, through its digital innovation hubs, has offered learning circles in basic ai (using the finnish elements of ai course as a foundation) and hosted presentations on various aspects of algorithms in everyday life. by abstracting algorithms to higher level concepts related directly to daily experience (using facebook is illustrative of many key ideas regarding algorithmic literacy), staff can obtain a sufficient overview from a variety of accessible, introductory texts or videos. perhaps most importantly, given the new and evolving nature of this technology, library staff should view themselves as co-learners. no matter the setting or context, an active learning approach is recommended with learners situated as makers as well as consumers.45 a review of the k–12 curricula regarding computational literacy identified active learning strategies based on projects, problem solving, cooperation, and games. the researchers recommend augmenting these with scaffolding strategies, storytelling, and aesthetic approaches.46 while intended for algorithmic literacy initiatives involving children, four design principles from dasgupta and mako are relevant for any demographic: https://friscolibrary.com/ https://www.torontopubliclibrary.ca/ https://www.elementsofai.com/ information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 7 1. make data analysis central and ensure the data is relevant to the learner, 2. manage risk by using sandboxes for experimentation, 3. respect community values about technology that may differ, and 4. support authenticity with real-world examples and scenarios.47 long and magerko document a set of 17 core competencies and 15 associated learning design considerations regarding ai literacy.48 taken together these represent the basis for an algorithmic literacy program for any demographic and any context. libraries are encouraged to seek partnerships and collaborations with schools (k–12 and higher education) as well as with non-profit advocacy and training groups.49 examples among these include the algorithmic literacy project (algorithmliteracy.org) and a.i. for anyone (https://aiforanyone.org). many technology companies also offer high quality programs and resources. however, a report from the public policy forum notes that digital literacy campaigns are “too often funded by the very companies that are contributing to the problem.”50 a key issue is the lack of assessment instruments. there are none for algorithmic literacy and few for computational thinking. the most prominent of the latter is skills based, focusing on concepts and operational practices and very little on the wider social and cultural implications.51 library experience with information literacy assessment can inform algorithmic literacy assessment by helping to balance skills and operational concerns with a wider focus on concepts and contextual awareness. information literacy and explainable ai (xai): unique library contributions while libraries can make contributions to algorithmic literacy through a variety of programs, resources, and advocacy initiatives, two specific areas suggest opportunities for unique contributions: algorithmic literacy as a part of information literacy and algorithmic literacy in support of “explainable ai” (xai). algorithmic literacy and information literacy annemaree lloyd describes the opacity and ubiquity of algorithms as “a wicked problem for librarians and archivists who have a vested interest in equitable access, informed citizenry and the maintenance of public memory” and insists that information literacy “provides resistance to the expansionist claims of algorithms, while at the same time ensuring that people harness the power of this culture to their advantage.”52 information literacy programs championed by libraries have been instrumental in raising awareness and skill building among their user communities. using information literacy programs as a scaffold, algorithmic literacy can be incorporated into these successful initiatives. however, given the current needs “machine learning and algorithms present frontstage in the information literacy constellation.”53 head et al., in their important 2020 study of algorithms and information literacy, present a view of student perspectives that is both troubling and optimistic. 54 the students expressed “a tangle of resignation and indignation” about the effects of algorithms on their lives. for them, algorithms obscure more than they reveal, privacy is compromised, “trust is dead,” and skepticism is total. the authors conclude that we face an “epistemological crisis” where algorithms are “stripping individuals of the responsibility to interpret the facticity of the information these systems give us when that interpretation has been performed by the algorithms themselves.” however, students also employed “defensive practices” against algorithms, utilized “multiple selves” to preserve their https://algorithmliteracy.org/ https://aiforanyone.org/ information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 8 privacy, and were keen to learn how to “fight back” against surveillance and algorithmic decisionmaking. this is a reminder that “while algorithms certainly do things to people, people also do things to algorithms.”55 people have “algorithmic capital” which they can use in “negotiation with algorithmic power.”56 with these findings, it seems clear that status quo information literacy programs will not address the unique challenges presented by algorithms. jason clark, scott young, and lisa janicke hinchliffe took up this challenge with a project funded by an imls grant.57 calling “algorithmic awareness” a “new competency,” these researchers identified a gap in the acrl framework for information literacy that revealed “a lack of an understanding around the rules that govern our software and shape our digital experiences.”58 those rules are the “invisible logic” of algorithms that need to be made transparent for users and library staff. deliverables from this project include an integrated curriculum, syllabus, and software prototype that respond uniquely to the pedagogical challenges of algorithmic literacy.59 in promoting ml (machine learning) literacy, ryan cordell also calls for a specific pedagogical approach that would “emphasize the situated-ness of ml training data and experiments, including the biases or oversights that influence the outcomes of academic, economic, and governmental ml processes.”60 recommendations from this report provide guidelines for developing staff expertise, running pilot projects, and creating toolsets and checklists supportive of responsible machine learning. algorithmic literacy and explainable ai (xai) perhaps a less obvious way for libraries to contribute to algorithmic literacy is through explainable ai (xai).61 difficulties in interrogating algorithms to assess bias, discrimination, and unfairness (as well as other deficiencies such as veracity and generalizability) have led to widespread interest in xai. the purpose of xai is to “enable human users to understan d, appropriately trust, and effectively manage the emerging generation of artificially intelligent partners” and to deploy ai systems that have “the ability to explain their rationale, characterize their strengths and weaknesses, and convey an understanding of how they will behave in the future.”62 there is complementarity between the objectives of xai and algorithmic literacy. both seek transparency, promote understanding, and facilitate accountability. both recognize the primacy of human agency in human-machine interaction. xai is accomplished through a variety of techniques, strategies, and processes. these can involve unambiguous proofs, technical and statistical interventions for verification and validation, and authorizations that rely on standards, audits, and policy directives.63 explanations are contextual. system designers, professionals, regulators, end users, and the general public need explanations specific to their objectives and tailored to their skills and knowledge. as algorithmic decision-making is increasingly embedded in the information tools, services, and resources provided by libraries and promoted to users, xai and algorithmic literacy can operate in close association. libraries can incorporate aspects of xai into algorithmic literacy programming and the principles of algorithmic literacy (and more generally information literacy) can inform how xai is sensitive and responsive to different explanatory needs. xai is still an emergent field but it has had, and will continue to have, a profound impact on the development of machine learning systems. the opportunity for library involvement is immediate: information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 9 librarians need to become well versed in these technologies, and participate in their development, not simply dismiss them or hamper them. we must not only demonstrate flaws where they exist but be ready to offer up solutions. solutions grounded in our values and in the communities we serve.64 a repeated message from lis researchers is that library-developed tools to interrogate ai systems are essential components in advancing algorithmic literacy. 65 these tools can address the complexity and opacity of machine learning systems and provide levels of explainability and transparency in contextually appropriate ways. one such tool, either as a stand-alone system or embedded in an existing discovery system, might provide a user with access to the nature, and potential bias, of the training data, the general efficacy of the learning algorithm(s) used, and the generalizability of the trained model to different contexts. this xai scorecard would integrate the objectives of xai, algorithmic literacy, and information literacy. by leveraging and developing library staff skills and by partnering with ai research and industry groups “libraries can become ideal sites for cultivating responsible and responsive ml.”66 padilla views this engagement as not just a technical initiative but a library-wide effort to promulgate “responsible operations” with ai, noting that library practices “that embed transparency and explainability increase the likelihood of organizational accountability.”67 conclusion algorithms are “the new power brokers in society” and “we are growing increasingly dependent on computational spectacles to see the world.”68 lash argues that this development has altered the rules by which society operates. constitutive rules (e.g., rules that define the boundaries of society) and regulative rules (e.g., the rules define how we operate in society) are now joined by “algorithmic, generative rules.” these rules are “compressed and hidden and we do not encounter them in the way that we encounter constitutive and regulative rules. yet this third type of generative rules is more and more pervasive in our social and cultural life of the post-hegemonic order.”69 algorithmic literacy is a means to understand this new set of rules and to encourage the skills and abilities so people can use algorithms and not be used by them. libraries have typically championed accessible technology and its effective use. the ubiquity of algorithmic decisionmaking and its profound impact on everyday lives makes the recognition and promotion of algorithmic literacy a critical new challenge and imperative for libraries of all types. information technology and libraries june 2021 algorithmic literacy and the role for libraries | ridley and pawlick-potts 10 endnotes 1 thomas h. cormen et al.,

endnotes bridging the gap: self-directed staff technology training | quinney, smith, and galbraith 205 kayla l. quinney, sara d. smith, and quinn galbraith bridging the gap: self-directed staff technology training of hbll patrons. as anticipated, results indicated that students frequently use text messages, social networks, blogs, etc., while fewer staff members use these technologies. for example, 42 percent of the students reported that they write a blog, while only 26 percent of staff and faculty do so. also, 74 percent of the students and only 30 percent of staff and faculty indicated that they belonged to a social network. after concluding that staff and faculty were not as connected as their student patrons are to technology, library administration developed the technology challenge to help close this gap. the technology challenge was a self-directed training program requiring participants to explore new technology on their own by spending at least fifteen minutes each day learning new technology skills. this program was successful in promoting lifelong learning by teaching technology applicable to the work and home lives of hbll employees. we will first discuss literature that shows how technology training can help academic librarians connect with student patrons, and then we will describe the technology challenge and demonstrate how it aligns with the principles of self-directed learning. the training will be evaluated by an analysis of the results of two surveys given to participants before and after the technology challenge was implemented. ■■ library 2.0 and “librarian 2.0” hbll wasn’t the first to notice the gap between librarians and students, mcdonald and thomas noted that “gaps have materialized,” and library technology does not always “provide certain services, resources, or possibilities expected by emerging user populations like the millennial generation.”1 college students, who grew up with technology, are “digital natives,” while librarians, many having learned technology later in life, are “digital immigrants.”2 the “digital natives” belong to the millennial generation, described by shish and allen as a generation of “learners raised on and confirmed experts in the latest, fastest, coolest, greatest, newest electronic technologies.”3 according to sweeny, when students use libraries, they expect the same “flexibility, geographic independence, speed of response, time shifting, interactivity, multitasking, and time savings” provided by the technology they use daily.4 students are undergraduates, as members of the millennial generation, are proficient in web 2.0 technology and expect to apply these technologies to their coursework—including scholarly research. to remain relevant, academic libraries need to provide the technology that student patrons expect, and academic librarians need to learn and use these technologies themselves. because leaders at the harold b. lee library of brigham young university (hbll) perceived a gap in technology use between students and their staff and faculty, they developed and implemented the technology challenge, a self-directed technology training program that rewarded employees for exploring technology daily. the purpose of this paper is to examine the technology challenge through an analysis of results of surveys given to participants before and after the technology challenge was implemented. the program will also be evaluated in terms of the adult learning theories of andragogy and selfdirected learning. hbll found that a self-directed approach fosters technology skills that librarians need to best serve students. in addition, it promotes lifelong learning habits to keep abreast of emerging technologies. this paper offers some insights and methods that could be applied in other libraries, the most valuable of which is the use of self-directed and andragogical training methods to help academic libraries better integrate modern technologies. l eaders at the harold b. lee library of brigham young university (hbll) began to suspect a need for technology training when employees were asked during a meeting if they owned an ipod or mp3 player. out of the twenty attendees, only two raised their hands—one of whom worked for it. perceiving a technology gap between hbll employees and student patrons, library leaders began investigating how they could help faculty and staff become more proficient with the technologies that student patrons use daily. to best serve student patrons, academic librarians need to be proficient with the technologies that student patrons expect. hbll found that a self-directed learning approach to staff technology training not only fosters technology skills, but also promotes lifelong learning habits. to further examine the technology gap between librarians and students, the hbll staff, faculty, and student employees were given a survey designed to explore generational differences in media and technology use. student employees were surveyed as representatives of the larger student body, which composes the majority kayla l. quinney (quinster27@gmail.com) is research specialist, sara d. smith (saradsmith@gmail.com) is research specialist, and quinn galbraith (quinn_galbraith@byu.edu) is library human resource training and development manager, brigham young university library, provo, utah. 206 information technology and libraries | december 2010 2.0,” a program that “focuses on self-exploration and encourages staff to learn about new technologies on their own.”24 learning 2.0 encouraged library staff to explore web 2.0 tools by completing twenty-three exercises involving new technologies. plcmc’s program has been replicated by more than 250 libraries and organizations worldwide,25 and several libraries have written about their experiences, including academic26 and public libraries.27 these programs—and the technology challenge implemented by hbll—integrate the theories of adult learning. in the 1960s and 1970s, malcolm knowles introduced the theory of andragogy to describe the way adults learn.28 knowles described adults as learners who (1) are self-directed, (2) use their experiences as a resource for learning, (3) learn more readily when they experience a need to know, (4) seek immediate application of knowledge, and (5) are best motivated by internal rather than external factors.29 the theory and practice of self-directed learning grew out of the first learning characteristic and assumes that adults prefer self-direction in determining and achieving learning goals, and therefore learners exercise independence in determining how and what they learn.30 these theories have had a considerable effect on adult education practice31 and employee development programs.32 when adults participate in trainings that align with the assumptions of andragogy, they are more likely to retain and apply what they have learned.33 ■■ the technology challenge hbll’s technology challenge is similar to learning 2.0 in that it encourages self-directed exploration of web 2.0 technologies, but it differs in that participants were even more self-directed in exploration and that they were asked to participate daily. these features encouraged more self-directed learning in areas of participant interest as well as habit formation. it is not our purpose to critique learning 2.0, but to provide some evidence and analysis to demonstrate the success of hands-on, self-directed training approaches and to suggest other ways for libraries to apply self-directed learning to technology training. the technology challenge was implemented from june 2007 to january 2008. hbll staff included 175 full-time employees, 96 of whom participated in the challenge. (the student employees were not involved.) participants were asked to spend fifteen minutes each day learning a new technology skill. hbll leaders used rewards to make the program enjoyable and to motivate participation: for each minute spent learning technology, participants earned one point, and when one thousand points were earned, the participant would receive a gift certificate to the campus bookstore. staff and faculty participated and tracked their progress through an online masters of “informal learning”; that is, they are accustomed to easily and quickly gathering information relevant to their lives from the internet and from friends. shish and allen claimed that millennials prefer “interactive, hyper-linked multimedia over the traditional static, textoriented printed items. they want a sense of control; they need experiential and collaborative approaches rather than formal, librarian-guided, library-centric services.”5 these students arrive on campus expecting “to handle the challenges of scholarly research” using similar methods and technologies.6 interactive technologies such as blogs, wikis, streaming media applications, and social networks, are referred to as “web 2.0.” abram argued that web 2.0 technology “could be useful in an enterprise, institutional research, or community environment, and could be driven or introduced by the library.”7 “library 2.0” is a concept referring to a library’s integration of these technologies; it is essentially the use of “web 2.0 opportunities in a library environment.”8 manesss described library 2.0 is user-centered, social, innovative, and provider of a multimedia experiences.9 it is a community that “blurs the line between librarian and patron, creator and consumer, authority and novice.”10 libraries have been using web 2.0 technology such as blogs,11 wikis,12 and social networks13 to better serve and connect with patrons. blogs allow libraries to “provide news, information and links to internet resources,”14 and wikis create online study groups15 and “build a shared knowledge repository.”16 social networks can be particularly useful in connecting with undergraduate students: millennials use technology to collaborate and make collective decisions,17 and libraries can capitalize on this tendency by using social networks, which for students would mean, as bates argues, “an informational equivalent of the reliance on one’s facebook friends.”18 students expect library 2.0—and as libraries integrate new technologies, the staff and faculty of academic libraries need to become “librarian 2.0.” according to abram, librarian 2.0 understands users and their needs “in terms of their goals and aspirations, workflows, social and content needs, and more. librarian 2.0 is where the user is, when the user is there.”19 the modern library user “needs the experience of the web . . . to learn and succeed,”20 and the modern librarian can help patrons transfer technology skills to information seeking. librarian 2.0 is prepared to help patrons familiar with web 2.0 to “leverage these [technologies] to make a difference in reaching their goals.”21 therefore staff and faculty “must become adept at key learning technologies themselves.”22 stephen abram asked, “are the expectations of our users increasing faster than our ability to adapt?”23 and this same concern motivated hbll and other institutions to initiate staff technology training programs. the public library of charlotte and mecklenburg county of north carolina (plcmc) developed “learning bridging the gap: self-directed staff technology training | quinney, smith, and galbraith 207 their ability to learn and use technology. to be eligible to receive the gift card, participants were required to take this exit survey. sixty-four participants, all of whom had met or exceeded the thousand-point goal, chose to complete this survey, so the results of this survey represent the experiences of 66 percent of the participants. of course, if those who had not completed the technology challenge had taken the survey the results may have been different, but the results do show how those who chose to actively participate reacted to this training program. the survey included both quantifiable and open-ended questions (see appendix b for survey results and a list of the open-ended questions). the survey results, along with an analysis of the structure of the challenge itself, demonstrates that the program aligns with knowles’s five principles of andragogy to successfully help employees develop both technology skills and learning habits. self-direction the technology challenge was self-directed because it gave participants the flexibility to select which tasks and challenges they would complete. garrison wrote that in a self-directed program, “learners should be provided with choices of how they wish to proactively carry out the learning process. material resources should be available, approaches suggested, flexible pacing accommodated, and questioning and feedback provided when needed.”34 hbll provided a variety of challenges and training sessions related to various technologies. technology challenge participants were given the independence to choose which learning methods to use, including which training sessions to attend and which challenges to complete. according to the exit survey, the most popular training methods were small, instructor-led groups, followed by self-learning through reading books and articles. group training sessions were organized by hbll leadership and addressed topics such as microsoft office, rss feeds, computer organization skills, and multimedia software. other learning methods included web tutorials, dvds, large group discussions, and one-on-one tutoring. the group training classes preferred by hbll employees may be considered more teacher-directed than self-directed, but the technology challenge was self-directed as a whole in that learners were given the opportunity to choose what they learned and how they learned it. the structure of the technology challenge allowed participants to set their own pace. staff and faculty were given several months to complete the challenge and were responsible to pace themselves. on the exit survey, one participant commented: “if i didn’t get anything done one week, there wasn’t any pressure.” another enjoyed flexibility in deciding when and where to complete the tasks: “i liked being able to do the challenge anywhere. when i had a few minutes between appointments, classes, board game called “techopoly.” participation was voluntary, and staff and faculty were free to choose which tasks and challenges they would complete. tasks fell into one of four categories: software, hardware, library technology, and the internet. participants were required to complete one hundred points in each category, but beyond that, were able to decide how to spend their time. examples of tasks included attending workshops, exploring online tutorials, and reading books or articles about a relevant topic. for each hundred points earned, participants could complete a mini-challenge, which included reading blogs or e-books, listening to podcasts, or creating a photo cd (see appendix a for a more complete list). participants who completed fifteen out of twenty possible challenges were entered into a drawing for another gift certificate. before beginning the challenge, all participants were surveyed about their current use of technology. on this survey, they indicated that they were most uncomfortable with blogs, wikis, image editors, and music players. these results provided a focus for technology challenge trainings and mini-challenges. while not all of these technologies may apply directly to their jobs, 60 percent indicated that they were interested in learning them. forty-four percent reported that time was the greatest impediment to learning new technology; therefore the daily fifteen-minute requirement was introduced with the hope that it was small enough to be a good incentive to participate but substantial enough to promote habit formation and allow employees enough time to familiarize themselves with the technology. although some productivity may have been lost due to the time requirement (especially in cases where participants may have spent more than the required time), library leaders felt that technology training was an investment in hbll employees and that, at least for a few months, it was worth any potential loss in productivity. because participants could chose how and when they learned technology, they could incorporate the challenge into their work schedules according to their own needs, interests, and time constraints. of ninety-six participants, sixty-six reached or exceeded the thousand-point goal, and eight participants earned more than two thousand points. ten participants earned between five hundred and one thousand points, and another six earned between one hundred and five hundred. although not all participants completed the challenge, most were involved to some extent in learning technology during this time. ■■ the technology challenge and adult learning after finishing the challenge, participants took an exit survey to evaluate the experience and report changes in 208 information technology and libraries | december 2010 were willing, even excited, to learn technology skills: 37 percent “agreed” and 60 percent “strongly agreed” that they were interested in learning new technology. their desire to learn was cultivated by the survey itself, which helped them recognize and focus on this interest, and the challenge provided a way for employees to channel their desire to learn technology. immediate application learners need to see an opportunity for immediate application of their knowledge: ota et al. explained that “they want to learn what will help them perform tasks or deal with problems they confront in everyday situations and those presented in the context of application to real life.”39 because of the need for immediate application, the technology challenge encouraged staff and faculty to learn technology skills directly related to their jobs—as well as technology that is applicable to their personal or home lives. hbll leaders hoped that as staff became more comfortable with technology in general, they would be motivated to incorporate more complex technologies into their work. here is one example of how the technology challenge catered to adult learners’ need to apply what they learn: before designing the challenge, hbll held a training session to teach employees the basics of photoshop. even though attendees were on the clock, the turnout was discouraging. library leaders knew they needed to try something new. in the revamped photoshop workshop that was offered as part of the technology challenge, attendees brought family photos or film and learned how to edit and experiment with their photos and burn dvd copies. this time, the class was full: the same computer program that before drew only a few people was now exciting and useful. focusing on employees’ personal interests in learning new software, instead of just on teaching the software, better motivated staff and faculty to attend the training. motivation as stated by ota et al., adults are motivated by external factors but are usually more motivated by internal factors: “adults are responsive to some external motivators (e.g., better job, higher salaries), but the most potent motivators are internal (e.g., desire for increased job satisfaction, self-esteem).”40 on the entrance survey, participants were given the opportunity to comment on their reasons for participating in the challenge. the gift card, an example of an external motivation, was frequently cited as an important motivation. but many also commented on more internal motivations: “it’s important to my job to stay proficient in new technologies and i’d like to stay current”; “i feel that i need to be up-to-date or meetings i could complete some of the challenges.” employees could also determine how much or how little of the challenge they wanted to complete: many reached well over the thousand-point goal, while others fell a little short. participants began at different skill levels, and thus could use the time and resources allotted to explore basic or more advanced topics according to their needs and interests. garrison had noted the importance of providing resources and feedback in self-directed learning.35 the techopoly website provided resources (such as specific blogs or websites to visit) and instructions on how to use and access technology within the library. hbll also hired a student to assist staff and faculty one-on-one by explaining answers to their questions about technology and teaching other skills he thought may be relevant to their initial problem. the entrance and exit surveys provided opportunities for self-reflection and self-evaluation by questioning the participants’ use of technology before the challenge and asking them to evaluate their proficiency in technology after the challenge. use of experience the use of experience as a source of learning is important to adult learners: “the richest resource for learning resides in adults themselves; therefore, tapping into their experiences through experiential techniques (discussions, simulations, problem-solving activities, or case methods) is beneficial.”36 the small-group discussions and one-onone problem solving made available to hbll employees certainly fall into these categories. small-group classes are one of the best ways to encourage adults to share and validate their experiences, and doing so increases retention and application of new information.37 the trainings and challenges encouraged participants to make use of their work and personal experiences by connecting the topic to work or home application. for example, one session discussed how blogs relate to libraries, and another helped participants learn adobe photoshop skills by editing personal photographs. need to know adult learners are more successful when they desire and recognize a need for new knowledge or skills. the role of a trainer is to help learners recognize this “need to know” by “mak[ing] a case for the value of learning.”38 hbll used the generational survey and presurvey to develop a need and desire to learn. the results of the generational survey, which demonstrated a gap in technology use between librarians and students, were presented and discussed at a meeting held before the initiation of the technology challenge to help staff and faculty understand why it was important to learn 2.0 technology. results of the presurvey showed that staff and faculty bridging the gap: self-directed staff technology training | quinney, smith, and galbraith 209 statistical reports or working with colleagues from other libraries.” ■■ “i learned how to set up a server that i now maintain on a semi-regular basis. i learned a lot about sfx and have learned some perl programming language as well that i use in my job daily as i maintain sfx.” ■■ “the new oclc client was probably the most significant. i spent a couple of days in an online class learning to customize the client, and i use what i learned there every single day.” ■■ “i use google docs frequently for one of the projects i am now working on.” participants also indicated weaknesses in the technology challenge. almost 20 percent of those who completed the challenge reported that it was too easy. this is a valid point—the challenge was designed to be easy so as not to intimidate staff or faculty who are less familiar with technology. it is important to note that these comments came from those who completed the challenge—other participants may have found the tasks and mini-challenges more difficult. the goal was to provide an introduction to web 2.0, not to train experts. however, a greater range of tasks and challenges could be provided in the future to allow staff and faculty more selfdirection in selecting goals relevant to their experience. to encourage staff and faculty to attend sponsored training sessions as part of the challenge, hbll leaders decided to double points for time spent at these classes. this certainly encouraged participation, but it lead to “point inflation”—perhaps being one reason why so many reported that the challenge was too easy to complete. the doubling of points may also have encouraged staff to spend more time in workshops and less time practicing or applying the skills learned. a possible solution would be offering 1.5 points, or offering a set number of points for attendance instead of counting per minute. it also may have been informative for purpose of analysis to have surveyed both those who did not complete the challenge as well as those who chose not to participate. because the presurvey indicated that time was the biggest deterrent to learning and incorporating new technology, we assume that many of those who did not participate or who did not complete the challenge felt that they did not have enough time to do so. there is definitely potential for further investigation into why library staff would not want to participate in a technology training program, what would motivate them to participate, and how we could redesign the technology challenge to make it more appealing to all of our staff and faculty. several library employees have requested that hbll sponsor another technology challenge program. because of the success of the first and because of continuing interest in technology training, we plan to do so in the future. we will make changes and adjustments according to the on technology in order to effectively help patrons”; “to identify and become comfortable with new technologies that will make my work more efficient, more presentable, and more accurate.” ■■ lifelong learning staff and faculty responded favorably to the training. none of the participants who took the exit survey disliked the challenge; 34 percent even reported that they strongly liked it. ninety-five percent reported that they enjoyed the process of learning new technology, and 100 percent reported that they were willing to participate in another technology challenge—thus suggesting success in the goal of encouraging lifelong technology learning. the exit survey results indicate that after completing the challenge, staff and faculty are more motivated to continue learning—which is exactly what hbll leaders hoped to accomplish. eighty-nine percent of the participants reported that their desire to learn new technology had increased, and 69 percent reported that they are now able to learn new technology faster after completing the technology challenge. ninety-seven percent claimed that they were more likely to incorporate new technology into home or work use, and 98 percent said they recognized the importance of staying on top of emerging technologies. participants commented that the training increased their desire to learn. one observed, “i often need a challenge to get motivated to do something new,” and another participant reported feeling “a little more comfortable trying new things out.” the exit survey asked participants to indicate how they now use technology. one employee keeps a blog for her daughter’s dance company, and another said, “i’m on my way to a full-blown googlereader addiction.” another participant applied these new skills at home: “i’m not so afraid of exploring the computer and other software programs. i even recently bought a computer for my own personal use at home.” the technology challenge was also successful in helping employees better serve patrons: “i can now better direct patrons to services that i would otherwise not have known about, such as streaming audio and video and e-book readers.” another participant felt better connected to student patrons: “i understand the students better and the things they use on a daily basis.” staff and faculty also found their new skills applicable to work beyond patron interaction, and many listed specific examples of how they now use technology at work: ■■ “i have

based on survey results. the purpose of a second technology challenge would be to reinforce what staff and faculty have already learned, to teach new skills, and to help participants remember the importance of lifelong learning when it comes to technology. ■■ conclusion hbll’s self-directed technology challenge was successful in teaching technology skills and in promoting lifelong learning—as well as in fostering the development of librarian 2.0. abram listed key characteristics and duties of librarian 2.0, including learning the tools of web 2.0; connecting people, technology, and information; embracing “nontextual information and the power of pictures, moving images, sight, and sound”; using the latest tools of communication; and understanding the “emerging roles and impacts of the blogosphere, web syndicasphere, and wikisphere.”41 survey results indicated that hbll employees are on their way to developing these attributes, and that they are better equipped with the skills and tools to keep learning. like plcmc’s learning 2.0, the technology challenge could be replicated in libraries of various sizes. obviously an exact replication would not be feasible or appropriate for every library—but the basic ideas, such as the principles of andragogy and self-directed learning could be incorporated, as well as the daily time requirement or the use of surveys to determine weaknesses or interests in technology skills. whatever the case, there is a great need for library staff and faculty to learn emerging technologies and to keep learning them as technology continues to change and advance. but the most important benefit of a self-directed training program focusing on lifelong learning is effective employee development. the goal of any training program is to increase work productivity—and as employees become more productive and efficient, they are happier and more excited about their jobs. on the exit survey, one participant expressed initially feeling hesitant about the technology challenge and feared that it would increase an already hefty workload. however, once the challenge began, the participant enjoyed “taking the time to learn about new things. i feel i am a better person/librarian because of it.” and that, ultimately, is the goal—not only to create better librarians, but also to create better people. notes 1. robert h. mcdonald and

an initial memorandum of understanding (mou) was drafted by the unlv libraries. this mou is still used by the libraries. the mou was discussed with all partners and ultimately signed by the director of each library. since the mou was signed nearly a decade ago, the system has continued to grow by all measures—size of the database, number of users, number of software modules comprising the complete system, and the financial and staff commitment toward support and maintenance. despite the emergence of a large number of other network-based technologies critical to library operations and services, the ils remains a critical system that supports many library operations. the research described in this paper developed in part because there is a dearth of published survey-based research of shared ils management and financial support. this article interweaves local existing practices with research findings. for brevity’s sake, the system shared by the unlv university libraries and four additional partners will be referred to as unlv’s system. to provide a relative sense of the footprint of each partner on the system, various measures can be used (see figure 1). ■■ survey method in april 2010, the authors administered a 20-question survey to the innovative user’s group (iug) via the group’s listserv. the survey focused on libraries that are part of a consortial or otherwise shared innovative ils. the innovative user’s group is the primary user’s group associated with the innovative ils and suite of products. the iug hosts a busy listserv, coordinates the annual north american conference devoted solely to the innovative system, and provides innovative customer-driven enhancement requests. to prevent multiple individuals from the same consortium responding to the survey, instructions indicated that only one individual from the main institution hosting the system should officially respond. given the anonymity of the survey and the desire to provide confidentiality, there is the possibility that some survey responses refer to the same system. the survey consisted primarily of multiple choice, “select all that apply,” and free-text response questions. the survey was divided into four broad topical areas: (1) background information; (2) funding; (3) support; and (4) training, professional development, and planning. the survey was open for a period of three weeks. because respondents could choose to skip questions, the number of responses received per question varied. on average, 43 individual responses were received for each question. innovative currently has more than 1,200 millennium ils installations.2 not all of those installations support multiple, administratively separate library entities. it is unknown the university of nevada, las vegas (unlv) university libraries has hosted and managed a shared integrated library system (ils) since 1989. the system and the number of partner libraries sharing the system has grown significantly over the past two decades. spurred by the level of involvement and support contributed by the host institution, the authors administered a comprehensive survey to current innovative interfaces libraries. research findings are combined with a description of unlv’s local practices to provide substantial insights into shared funding, support, and management activities associated with shared systems. s ince 1989, the university of nevada, las vegas university libraries has hosted and managed a shared integrated library system (ils). currently, partners include the university of nevada, las vegas university libraries (consisting of one main and three branch libraries, and hereafter referred to as unlv libraries); the administratively separate unlv law library; the college of southern nevada (a community college system consisting of three branch libraries); nevada state college; and the desert research institute. the original ils installation included just the unlv libraries and the clark county community college (now known as the college of southern nevada). the desert research institute joined in the early 1990s, the unlv law library joined with the establishment of the william j. boyd school of law in 1998, and, finally, nevada state college joined upon its creation in 2002. over time, the technological underpinnings of the ils have changed tremendously and have migrated firmly into a webbased environment unknown in 1989. the system was migrated to innovative interfaces’ current java-based platform, millennium, beginning in 1999. since the original installation, there have been three major full hardware migrations, in 1997, 2002, and 2009. over time, regular innovative software updates, as well as additional purchased software modules, have greatly extended both the staff and end user functionality of the ils. in early 2001, unlv and its partners conducted a marketplace assessment of ils vendors catering to academic customers.1 the assessment reaffirmed the consortia’s commitment to innovative interfaces. shortly thereafter, jason vaughan (jason.vaughan@unlv.edu) is director, library technologies, university of nevada las vegas. kristen costello (kristen.costello@unlv.edu) is systems librarian, university of nevada las vegas. management and support of shared integrated library systems | vaughan and costello 63 partners originally purchased the system together; 20 (38.5 percent) indicated they purchased the system with some of their current existing partners, while 9 (17.3 percent) indicated they as the main institution originally and solely purchased the system. several of the entities sharing the unlv libraries’ system did not even exist when the ils was originally purchased; only two of the current partners shared the original purchase cost of the system. another background question sought to understand how partners potentially individualize the system despite being on a shared platform. innovative, and likely other similar ils vendors, offers several products to help libraries better manage and control their holdings and acquisitions. of potential benefit to staff operations and workflow, innovative offers the option to have multiple acquisitions and/or serials control units, which provide separate fund files and ranges of order records for different institutions sharing the ils system. of 51 responses received, 44 respondents (86.3 percent) indicated they had multiple acquisitions and serials units and 7 (13.7 percent) do not. innovative offers two web-based discovery interfaces for patrons: the traditional online public access catalog, known as webpac, and their version of a next-generation discovery layer, known as encore. of potential benefit to staff as well as patrons, innovative offers “scoping” modules that help patrons using one of the web-based discovery interfaces, as well as staff using the millennium staff modules. the scoping module allows holdings segmentation by location or material type. scopes allow libraries to define their collections and offer their patrons the option to search just the collection of their applicable library. forty-six (88.5 percent) of the 52 respondents indicated they use scoping and 6 (11.5 percent) do not. unlv how many shared innovative library systems exist. while a true response rate cannot be determined, such a measure is not critical for this research. the survey questions with summarized results are provided in appendix a. ■■ survey background unlv’s system, with only five unique library entities, is a “small” system when compared with survey responses. survey respondents indicated a range from 2 to 80 unique members sharing their system. of the 48 responses received for this background question, 26 (54 percent) indicated 10 or fewer partners on the system. seven (14.6 percent) indicated 40 or more partners. the average number of partners sharing an ils implementation was 18 and the median was 8.5. there can be varying levels of partnership within a shared ils system. unlv’s instance is a rather informal partnership. some survey respondents indicated the existence of a far more structured or dedicated support group not directly associated with any particular library. one respondent noted they have a central office comprised of an executive director and two additional staff, responsible for ils administration; this central office reports to a board of directors, comprised of library directors for each member library. another indicated they have a central office responsible not only for the ils, but for other things such as wide and local area networks and workstation support. one respondent indicated that they are actually a consortium of consortia, with 9 hosts each comprised of anywhere from 4 to 11 libraries. twenty-three respondents out of 52 (44.2 percent) indicated that they and all of their current existing full-time library staff bibliographic

64 information technology and libraries | june 2011 share of funding toward annual maintenance based on their number of staff licenses, as shown in figure 1. ■■ funding support from partners mous appear to include funding and budgeting information more than any other discrete topic. direct support costs can include the maintenance support costs paid to one or more vendors, costs for additional vendor authored software modules purchased in addition to the base software, and, perhaps, licensing costs associated with a database or operating system used by the ils (e.g., an oracle license for oracle based ils systems). there are many parameters by which costs could be determined for partners, and, given the dearth of published research on the topic, a chief focus of this research sought more information on what factors were used by other consortia. the authors brainstormed 10 elements that could potentially figure into the overall cost sharing method. thirty-eight respondents provided information on factors playing a role in their cost sharing arrangements, illustrated in figure 2. respondents could mark more than one answer for this question, as more than one factor could be involved. the top two factors relate directly to vendor costs— whether annual support costs or acquisition of new vendor software. hardware placed third in overall frequency; for innovative and likely for other ils systems, ils hardware can be purchased from the vendor or an approved platform can be sourced from a reseller directly. support costs from third parties and the number of staff login ports were each identified as a factor by more than a third of all respondents. ■■ software purchases depending on the software, additional modules extending the system capabilities can benefit a single partner, or, in unlv’s experience, all partners on the system. traditionally, the unlv libraries have had the largest operating budget of the group, and a majority of new software requests have come internally from unlv libraries staff. over the past 20 years, the unlv libraries have fully funded the initial purchase costs of a majority of the software extending the system, regardless of whether it benefits just the unlv libraries or all system partners. there are numerous exceptions where the partner libraries have contributed funding, including significant start-up costs associated with the unlv law library joining the system in 1998 and the addition of nevada state college in 2002. in both instances, those bodies funded required and recommended software directly applicable has multiple serials and acquisitions units as well as multiple scopes configured to help segment the records for each entities’ particular collection. innovative offers various levels of maintenance support. unlv’s level of support includes the vendor supplying services such as application troubleshooting resolution, software updates, and some degree of operating system and hardware configuration and advice. unlv also contracts with the hardware vendor for hardware maintenance and underlying operating system support. the unlv libraries have had the opportunity to hire fully qualified and capable technical staff to provide a high level of support for the ils. unlv’s level of vendor support has evolved from an original full turnkey installation with innovative providing all support to a present level of more modest support. nearly half of all survey respondents, 25 of 52 (48.1 percent) indicated they had a turnkey arrangement with innovative; the remaining 27 respondents had a lesser level of support. maintenance and support obviously carry a cost with one or more third party providers. the majority of the respondents, 40 of 51 (78.4 percent), indicated there is a cost-sharing structure in place where maintenance support costs related to the ils are spread across partner libraries. six respondents (11.8 percent) indicated the main institution fully funds the maintenance support costs. the unlv libraries drafted the first and current mou in 2002 for all five entities sharing the ils system. thirty-five of 51 survey respondents (68.6 percent) indicated they, too, have a mou in place. unlv’s mou is a basic document, two pages in length, split into the following sections: background; acquisition of new or additional hardware; acquisition of new or additional software; annual maintenance associated with the primary vendor and third party suppliers and, importantly, the associated cost allocation method for how annual support costs are split between the partners; how new products are purchased from the vendor; and management and support responsibilities of the hosting institution. many of the survey respondents provided details on items contained in their own mous, which can be clustered into several broad categories. these include budgeting, payments, funding formulas; general governance and voting matters; support (e.g., contractual service responsibilities, responsibilities of member libraries); equipment (e.g., title and use of equipment, who maintains equipment); and miscellaneous. this latter category includes items such as expectations for record quality; network requirements/ restrictions; fine collection; and holds management. the majority of unlv’s mou addresses shared costs for annual maintenance. unlv’s cost-sharing structure is simple. the system has a particular number of associated staff (simultaneous login) licenses, which have gradually increased as the libraries have grown. logins are separated by institution, and each member is assessed their management and support of shared integrated library systems | vaughan and costello 65 annual maintenance bill and all partners help maintain new software acquisitions by contributing toward the annual maintenance. regarding new software acquisitions, cost-sharing practices varied between 44 respondents providing information in the survey. eight (18.2 percent) indicated there is consultation with other partners and there is some arrangement to share costs between the majority or all partners sharing the system. two respondents (4.5 percent) indicated the institution expressing the initial interest in the product fully funds the purchase. nineteen respondents (43.2 percent) indicated that they have had instances of both these scenarios (shared funding and sole funding). two respondents (4.5 percent) indicated they could not recall ever adding any additional software. thirteen respondents (29.5 percent) offered details to their operation such as additional serials and accounting units (for the law library), check-in and order records, and staff licenses. in addition, when the system was migrated from the aging text-based system (innopac) to the current millennium java-based gui system in 1999, the current partners contributed toward the upgrade cost based on number of staff licenses. partner institutions have continued to fund items of sole benefit to their operation, such as adding staff licenses or required network port interfaces associated with patron self-check stations installed at their facilities. during the 2000s, the unlv libraries have fully funded a majority of software of potential benefit to all partners, such as the electronic resource management module, the encore next generation discovery platform, and various opac/encore enhancements. software additions typically increase the figure 2. cost-sharing formula factors t h e a m o u n t o f th e o ve ra ll ye a rl y in

2011 applied, the number of staff users has increased significantly, and the system was migrated to an underlying oracle database in 2004. since the original system was purchased in 1989 and fully installed in 1990, the central, locally hosted server has been replaced three times, in 1997, 2002, and 2009. partners contributed toward the costs of the server upgrades in 1997 and 2002, while the unlv libraries fully funded the 2009 upgrade. software and hardware components comprising the backup system have been significantly enhanced with a modern system capable of the speed, capacity, and features needed to perform appropriately in the short backup window available each night. unlv funded the initial backup software and hardware, and the partner institutions contribute toward the annual maintenance associated with the backup equipment and software. one survey question focused on major central infrastructure supporting the ils (defined as items exceeding $1,000 and with several examples listed). the question did not focus on hardware that could be provided by ils vendors benefiting a single partner, such as self-check stations or inventory devices. fourteen (31.8 percent) of the 44 respondents indicated that if major new hardware was needed, there was consultation with other partners, and, if purchased, a cost-sharing agreement was arranged. two respondents (4.5 percent) indicated the institution expressing the initial interest fully funds the purchase and seven respondents indicated they’ve had instances in the past of both these scenarios. three respondents (6.8 percent) indicated their shared system hardware had never been replaced or upgraded to their knowledge. nineteen respondents provided information on alternate scenarios or otherwise more details as to local practice. several indicated a separate fund is maintained solely for large ils system-related improvements or ils related purchases. revenue for these funds can be built up over time through maintenance and use payments by partner libraries or by a small additional fee earmarked for future hardware replacement needs collected each year. one respondent indicated they have been able to get grant funds to cover major purchases. with few exceptions, the majority of free text responses indicated that costs for major purchases were shared by partners or otherwise funded by the central consortium or cooperative agency. as with regular annual maintenance and new software purchases, various elements can determine what portion of hardware replacement costs are borne by partner libraries. this includes number of staff licenses (21.9 percent of responses), institutional fte count (15.6 percent), number of bibliographic or item records (15.6 percent), and number of patron records (9.4 percent). twenty respondents provided additional information. several indicated that the costs are split evenly across all partners. several indicated that population served was a factor. others reiterated that costs for central hardware on other scenarios. several indicated that if a product is directly applicable to only one library, such as self-check interfaces and additional acquisition units, then the library in need fully funds the purchase, which mirrors the local practice at unlv. several respondents indicated that if a product benefits all libraries, then costs are shared equally. one respondent indicated that the partner libraries discuss the potential item, and collectively they may choose not to purchase, even if one or more partners are very interested. in such cases, those partners have the option to purchase the product and must agree to make it available to all partners. several respondents indicated that, as the largest entity using the shared system, they generally always purchased new software for their operation as needed, with the associated benefit that the other partners of the system were allowed to use the software as well. three respondents reiterated that a central office funds add-on modules, in one case from funding set aside each year for system improvements. a fourth respondent indicated that a “joiners fee” fund, built up from new members joining the system, allows for the purchase of new software. clearly there are many scenarios of how new software is funded. generally, regardless of funding source, sole or share, if a product can benefit all partners, it’s allowed to do so. thirty-six survey respondents provided details on what factors determine how much each partner contributes toward new software purchases. seven respondents (19.4 percent) indicated the number of staff licenses plays a role (as in the unlv model). three respondents (8.3 percent) indicated that institution fte played a role, while three other respondents indicated that the number of partner bibliographic/item records played a role. the majority of respondents, 25 (69.4 percent) provided alternate scenarios or otherwise more information. nine of these 25 respondents indicated costs were split evenly across all partners. several indicated that the formula used for determining maintenance costs was also applied to new software purchases. four respondents indicated that the library service population was a factor. two indicated that circulation counts were a factor. one indicated that it’s negotiated on a per purchase basis, based on varying factors. ■■ hardware purchases hardware needs related to the underlying infrastructure, such as server(s), disk space, and backup equipment increases as the ils grows. unlv’s ils installation has grown tremendously. new software modules have been purchased, application architecture changes occurred with the release of the millennium suite in the late 1990s, regular annual updates to the system software have been management and support of shared integrated library systems | vaughan and costello 67 each partner institution. each module coordinator served as the contact person charged with maintaining familiarity with the functions and features of a particular module, testing enhancements within new releases, keeping other staff informed of changes, and alerting the system vendor of any problems with the module. annually, module coordinators were to consider new software and prioritize and recommend ils software the library should consider purchasing. module coordinators were tasked to maintain a system-wide view of the ils and alert others if they discovered problems or made changes to the ils that could affect other areas of the system. in addition, module coordinators were encouraged to subscribe to the iug listserv to monitor discussions and to maintain awareness of overall system issues. all staff had access to the system’s user manual but if they had questions on system features or functions, the module coordinator served as an additional resource. in addition, any bug reports were provided to the most appropriate module coordinator, who would contact innovative. the unlv systems staff, which has grown over time and is now part of the library technologies division, was responsible for all hardware and networking problems, and for scheduling and verifying nightly data backups. the systems department coordinated any new software installations with the module coordinators group, library staff, and library partners. in 2006, the unlv libraries reorganized and hired a dedicated systems librarian focused on the ils. the systems librarian’s principal job responsibility is to serve as the central administrator and site coordinator of the unlv libraries’ shared ils. responsibilities include communicating with colleagues regarding current system capabilities, monitoring vendor software developments, monitoring how other libraries utilize their innovative systems, and recommending enhancements. the systems librarian is the site contact with innovative and coordinates and monitors support calls, software and patch upgrades, and new software module installations. the position serves as the contact person for the shared institutions whenever they have questions or issues with the ils. the systems librarian has taken over much of the work previously coordinated through the module coordinators group. while the formal module coordinators group no longer exists, module experts still provide assistance as needed, and consultation always occurs with partners on system-wide issues as they arise. unlv is not unique in how it manages their ils. in the survey results, 36 respondents (87.8 percent) indicated there is a dedicated individual at the main institution who has a primary responsibility of overseeing the ils. to help clarify the responses, “primary responsibility” is defined as individuals spending more than half their time devoted to support, research, troubleshooting, and system administration duties related to the ils. the authors replacements are determined by the same formula used for assessing the share of annual maintenance. ■■ additional purchases the last funding-related survey question asked if ongoing content enrichment services were subscribed to, and if so, to describe how the cost share amount is determined for partner libraries. content enrichment services can provide additional evaluative content such as book cover images, table of contents (toc), and book reviews. unlv subscribes to a toc service as well as an additional service providing book covers, reviews, and excerpts. partner institutions contribute to the annual service charge associated with the toc service and pay for each record enhanced at their library. unlv fully funds the book cover/review/excerpt service that benefits all partners. fourteen of the 43 survey respondents (32.6 percent) indicated they did not subscribe to enrichment services. twelve respondents (27.9 percent) indicated they had one or more enrichment services and that the costs were fully funded by the main institution. seventeen respondents (39.5 percent) subscribe to enrichment services and that the costs are shared. several indicated the existing cost-sharing formula used for other assessments (annual maintenance, hardware, or nonsubscription-based software) is also used for the ongoing enrichment services. one respondent indicated they maintain a collective fund for enrichment services and estimate the cost of all shared subscriptions; this figure is integrated into the share each institution contributes to the central fund annually. one respondent indicated that their system only uses free enrichment services. ■■ support the next section of the survey addressed staff support efforts related to management of the ils. twenty years ago when unlv installed its ils, staff support included one librarian and one additional staff; both focused on various aspects of system support, from maintaining hardware to working with the vendor, in addition to having other primary job responsibilities completely unrelated to the ils. in addition, over time, functional experts developed for particular modules of the system, such as cataloging, acquisitions, circulation, and serials control. this group of functional experts eventually became known as the unlv innovative module coordinators group, which was chaired by the head of the library systems department. this group met quarterly and included experts from unlv as well as one representative from 68 information technology and libraries | june 2011 solely by the main library. typical system administration activities include managing and executing mid-release and major release software upgrades (95.2 percent of all respondents indicated the main library is solely responsible); managing, coordinating, and scheduling new products for installation (95.2 percent); monitoring disk space (95 percent); and scheduling and monitoring backups (92.9 percent). unlv’s ils support model is very similar to the survey results. the systems librarian at unlv manages all software upgrades, as well as coordinating and scheduling new ils software product and module installs. the library technologies division monitors and schedules the nightly backups and diskspace usage. certain unlv libraries staff and selected individuals from the partner libraries are authorized to open support calls with the system vendor, although the systems librarian often handles this activity herself. other functions, such as maintaining the year-to-date and last year circulation statistics are also performed by the unlv libraries systems librarian. updating circulation parameters are tasks best performed by each of the created a list of 20 duties related to ils system administration and asked respondents to indicate whether: the main library or a central consortial or cooperative office dedicated to the ils handles this particular duty; the duty is shared between the main library and partner libraries; or the duty is handled by just a partner library. as illustrated in figure 3, the survey results overwhelmingly show that the main library in a shared system provides the majority of system administration support. only two tasks were broadly shared between the main library and partner libraries; maintenance of the institution’s records (bibliographic, item, patron, order, etc.) and maintaining network and label printers. other shared tasks included changes to the circulation parameters tables (e.g., configuring loan rules and specifying open hours and days closed tables for materials they themselves circulate) with 40.5 percent of the respondents indicating this as a shared responsibility, opening support calls with the vendor (38.1 percent), monitoring bounced export and fts mail (33.3 percent), and account management (31 percent). the more typical system administration activities are done a c c o u n t m a n a g e

groups is as varied as the libraries. some groups meet quarterly (33.3 percent) or monthly (20 percent) but the majority meet at other frequencies (40 percent), such as every other month or twice a year. some libraries use e-mail to communicate as opposed to having regular in-person meetings. in addition to a standing committee focused on the ils, and similar to unlv’s experience, libraries may have finite working groups to implement particular products. ■■ training, professional development, and planning the survey also focused on training, professional development, and planning activities related to the ils. there are many methods that library staff can use to stay current with their ils. most training methods typically include in-person workshops or online tutorials, as well as other venues for professional development, such as conference attendance. the authors were interested in how libraries sharing an ils determined training needs and who was responsible for the training. the survey results showed that libraries value a variety of training opportunities, partner institutions, with advice and assistance as necessary provided by the systems librarian. the authors were interested if an ils oversight body exists with other shared systems, and, if so, what issues are discussed. responses indicated that a variety of groups exist, and, in some instances, multiple groups may exist within one consortia (some groups have a more specific ils focus and others a more tangential involvement). as illustrated in figure 4, a minority of respondents, 11 of 41 (26.8 percent), indicated that they do not have a group providing ils oversight. if such a group exists, respondents were allowed to select various predefined duties performed by that group. twenty-three respondents indicated the group discusses purchasing decisions. respondents also indicated that such a group also discusses the impact of the vendor enhancements offered by mid-release and regular full-releases (19), and when to schedule the upgrades (12). the absence of an oversight group doesn’t imply that consultation doesn’t occur, rather, it may be the responsibility of an individual as opposed to an effort coordinated by a group. some libraries also have module-driven committees, which disseminate information, introduce new ideas, and try to promote cohesiveness throughout the consortium. other duties that such an oversight group may focus on include workflow issues, discussion of system issues, figure 4. issues discussed by ils oversight body updates on unresolved problem calls with

regarding cost sharing, support, and rights and responsibilities. in conducting this background research, a paucity of published literature was observed, and thus the authors hope the findings above may help other established consortia, who may be interested in reviewing or tweaking their current mous or more formalized agreements likely in place. it may also provide some considerations for libraries considering initiating a shared ils instance, something that, given the current recession, may be a topic to consider. given that nearly a decade has passed since the original unlv mou was drafted and agreed to, several revisions will be proposed and drafted. this includes formalization of how costs are divided for enrichment services (new since the original mou), and formalization in writing of the coordination role of the systems librarian in her capacity as chief manager of the ils. other ideas gathered from survey responses are worth consideration, such as a base additional fee contributed each year (above and beyond the fee accessed as determined by staff licenses). such a fee could help recoup real, sometimes significant costs associated with the system, such as the purchase of additional software benefitting all players (often, in practice funded solely by the main library). such a fee could also help recoup more tangential (but still real) expenses, such as replacement of backup media. however, at the time of writing, tweaking (increasing) the fee assessed to partner institutions is a delicate issue. as with many other institutions of learning and their associated libraries, the nevada system of higher education has been particularly hard hit with funding cuts, even when compared against serious cuts experienced by colleagues nationwide. by all measures (unemployment, state budget shortfall, foreclosures, etc.) nevada has been one of the hardest hit states in the current recession. while knowledge gained from this survey was useful (and current), what effect it will have in changing the cost structure is, now, on hold. in the spirit of support among the libraries in the same system of higher education, and in continuing to demonstrate serious shared efficiencies (by maintaining one joint system as opposed to five individual systems), no new fee structure will be implemented in the short term. at the appropriate time, different costing structures such as those elicited in the survey results will merit closer attention. references 1. jason vaughan, “a library’s integrated online library system: assessment and new

indicating that both the main library and one or more partner libraries participate in this activity. attendance at the national and regional iug meetings was also valued highly by libraries with 26 respondents (66.7 percent) indicating both the main libraries and their partner libraries having a staff member attend such meetings in the past 5 years. sixteen respondents (64 percent) indicated both the main library and their partner libraries regularly send staff to the american library association annual conference and midwinter meeting. iug typically has a meeting the friday before the midwinter meeting. attendance at training workshops held at the vendor headquarters, as well as online training, is an activity in which the main library participates more frequently than the partner libraries (61.1 percent). complete survey results are provided in appendix a, available at http://www.lita.org/ala/mgrps/divs/lita/ ital/302011/3002jun/pdf/vaughan_app.pdf. ■■ research summary and future directions integrated library systems shared by multiple partners hold the promise of shared efficiencies. given a rather significant number of responses, shared systems appear to be quite common, ranging from a few partners to systems with many partners. perhaps reflecting this, shared systems range from loose federations of library partners to shared systems managed by a more formalized, official consortium. a majority of libraries with shared systems have a mou or other official documents to help define the nature of the relationship, focusing on such topics as budgeting, payments, and funding formulas; general governance and voting matters; support; and equipment. most libraries sharing a system have a method or funding formula outlining how the ils is funded on an annual basis and the contributions provided by each partner. such methods can include not only annual maintenance, but also the procurement of new hardware and software extending the system capabilities. while many support functions are carried out by a central office or staff at the main library hosting the shared system, partner libraries often participate in annual user group and library association conferences where they help stay abreast of vendor ils developments. the research above describes the authors’ investigations into management of shared integrated library systems. in particular, the authors were interested in how other consortia sharing an ils managed their system, generating collaborative systems for digital libraries | visser and ball 187 marijke visser and mary alice ball the middle mile: the role of the public library in ensuring access to broadband of fundamentally altering culture and society. in some circles the changes happen in real time as new web-based applications are developed, adopted, and integrated into the user’s daily life. these users are the early adopters; the internet cognoscenti. second tier users appreciate the availability of online resources and use a mix of devices to access internet content but vary in the extent to which they try the latest application or device. the third tier users also vary in the amount they access the internet but have generally not embraced its full potential, from not seeking out readily available resources to not connecting at all.1 regardless of the degree to which they access the internet, all of these users require basic technology skills and a robust underlying infrastructure. since the introduction of web 2.0, the number and type of participatory web-based applications has continued to grow. many people are eagerly taking part in creating an increasing variety of web-based content because the basic tools to do so are widely available. the amateur, creating and sharing for primarily personal reasons, has the ability to reach an audience of unprecedented size. in turn, the internet audience, or virtual audience, can select from a vast menu of formats, including multimedia and print. with print resources disappearing, it is increasingly likely for an individual to only be able to access necessary material online. web-based resources are unique in that they enable an undetermined number of people, personally connected or complete strangers, to interact with and manipulate the content thereby creating something new with each interaction and subsequent iteration. many of these new resources and applications require much more bandwidth than traditional print resources. with the necessary technology no longer out of reach, a crosssection of society is affecting the course the twenty-first century is taking vis à vis how information is created, who can create it, and how we share it.2 in turn, who can access web-based content and who decides how it can be accessed become critical questions to answer. as people become more adept at using web-based tools and eager to try new applications, the need for greater broadband will intensify. the economic downturn is having a marked effect on people’s internet use. if there was a preexisting problem with inadequate access to broadband, current circumstances exacerbate it to where it needs immediate attention. access to broadband internet today increases this paper discusses the role of the public library in ensuring access to the broadband communication that is so critical in today’s knowledge-based society. it examines the culture of information in 2010, and then asks what it means if individuals are online or not. the paper also explores current issues surrounding telecommunications and policy, and finally seeks to understand the role of the library in this highly technological, perpetually connected world. i n the last twenty years library collections have evolved from being predominantly print-based to ones that have a significant digital component. this trend, which has a direct impact on library services, has only accelerated with the advent of web 2.0 technologies and participatory content creation. cutting-edge libraries with next generation catalogs encourage patrons to post reviews, contribute videos, and write on library blogs and wikis. even less adventuresome institutions offer a variety of electronic databases licensed from multiple publishers and vendors. the piece of these library portfolios that is at best ignored and at worst vilified is the infrastructure that enables internet connectivity. in 2010, broadband telecommunication is recognized as essential to access the full range of information resources. telecommunications experts articulate their concerns about the digital divide by focusing on firstand last-mile issues of bringing fiber and cable to end users. the library, particularly the public library, represents the metaphorical middle mile providing the public with access to rich information content. equally important, it provides technical knowledge, subject matter expertise, and general training and support to library users. this paper discusses the role of the public library in ensuring access to the broadband communication that is so critical in today’s knowledge-based society. it examines the culture of information in 2010, and then asks what it means if individuals are online or not. the paper also explores current issues surrounding telecommunications and policy, and finally seeks to understand the role of the library in this highly technological, perpetually connected world. ■■ the culture of information information today is dynamic. as the internet continues on its fast paced, evolutionary track, what we call ‘information’ fluctuates with each emerging web-based technology. theoretically a democratic platform, the internet and its user-generated content is in the process marijke visser (mvisser@alawash.org) is information technology policy analyst and mary alice ball (maryaliceball@yahoo .com) former chair, telecommunications subcommittee, office for information technology policy, american library association, washington, dc. 188 information technology and libraries | december 2010 the geographical location of a community will also influence what kind of internet service is available because of deployment costs. these costs are typically reflected in varying prices to consumers. in addition to the physical layout of an area, current federal telecommunications policies limit the degree to which incentives can be used on the local level.7 encouraging competition between isps, including municipal electric utilities, incumbent local exchange carriers, and national cable companies, for example, requires coordination between local needs and state and federal policies. such coordinated efforts are inherently difficult when taking into consideration the numerous differences between locales. ultimately, though, all of these factors influence the price end users must pay for internet access. with necessary infrastructure and telecommunications policies in place, there are individual behaviors that also affect broadband adoption. according to the pew study, “home broadband adoption 2008,” 62 percent of dial-up users are not interested in switching to broadband.8 clearly there is a segment of the population that has not yet found personal relevance to high-speed access to online resources. in part this may be because they only have experience with dial-up connections. depending on dial-up gives the user an inherently inferior experience because bandwidth requirements to download a document or view a website with multimedia features automatically prevent these users from accessing the same resources as a user with a high-speed connection. a dial-up user would not necessarily be aware of this difference. if this is the only experience a user has it might be enough to deter broadband adoption, especially if there are other contributing factors like lack of technical comfort or availability of relevant content. motivation to use the internet is influenced by the extent to which individuals find content personally relevant. whether it is searching for a job and filling out an application, looking at pictures of grandchildren, using skype to talk to a family member deployed in iraq, researching healthcare providers, updating a personal webpage, or streaming video, people who do these things have discovered personally relevant internet content and applications. understanding the potential relevance of going online makes it more likely that someone would experiment with other applications, thus increasing both the familiarity with what is available and the comfort level with accessing it. without relevant content, there is little motivation for someone not inclined to experiment with internet technology to cross what amounts to a significant hurdle to adoption. anthony wilhelm argues in a 2003 article discussing the growing digital divide that culturally relevant content is critical in increasing the likelihood that non-users will want to access web-based resources.9 the scope of the issue of providing culturally relevant content is underscored in the 2008 pew study, the amount of information and variety of formats available to the user. in turn more content is being distributed as users create and share original content.3 businesses, nonprofits, municipal agencies, and educational institutions appreciate that by putting their resources online they reach a broader segment of their constituency. this approach to reaching an audience works provided the constituents have their own access to the materials, both physically and intellectually. it is one thing to have an internet connection and another to have the skill set necessary to make productive use of it. as reported in job-seeking in u.s. public libraries in 2009, “less than 44% of the top 100 u.s. retailers accept instore paper applications.”4 municipal, state, and federal agencies are increasingly putting their resources online, including unemployment benefit applications, tax forms, and court documents.5 in addition to online documents, the report finds social service agencies may encourage clients to make appointments and apply for state jobs online.6 many of the processes that are now online require an ability to navigate the complexities of the internet at the same time as navigating difficult forms and websites. the combination of the two can deter someone from retrieving necessary resources or successfully completing a critical procedure. while early adopters and policy-makers debate the issues surrounding internet access, the other strata of society, knowingly or not and to varying degrees, are enmeshed in the outcomes of these ongoing discussions because their right to information is at stake. ■■ barriers to broadband access by condensing internet access issues to focus on the availability of adequate and sustainable broadband, it is possible to pinpoint four significant barriers to access: price, availability, perceived relevance, and technical skill level. the first two barriers are determined by existing telecommunications infrastructure as well as local, state, and federal telecommunications policies. the latter barriers are influenced by individual behaviors. both divisions deserve attention. if local infrastructure and the internet service provider (isp) options do not support broadband access to all areas within its boundaries, the result will be that some community members can have broadband services at home while others must rely on work or public access computers. it is important to determine what kind of broadband services are available (e.g., cable, dsl, fiber, satellite) and if they are robust enough to support the activities of the community. infrastructure must already be in place or there must be economic incentive for isps to invest in improving current infrastructure or in installing new infrastructure. generating collaborative systems for digital libraries | visser and ball 189 at all. success hinges on understanding that each community is unique, on leveraging its strengths, and on ameliorating its weaknesses. local government can play a significant role in the availability of broadband access. from a municipal perspective, emphasizing the role of broadband as a factor in economic development can help define how the municipality should most effectively advocate for broadband deployment and adoption. gillett offers four initiatives appropriate for stimulating broadband from a local viewpoint. municipal governments can ■■ become leaders in developing locally relevant internet content and using broadband in their own services; ■■ adopt policies that make it easier for isps to offer broadband; ■■ subsidize broadband users and/or isps; or ■■ become involved in providing the infrastructure or services themselves.12 individually or in combination these four initiatives underscore the fact that government awareness of the possibilities for community growth made possible by broadband access can lead to local government support for the initiatives of other local agencies, including nonprofit, municipal, or small businesses. agencies partnering to support community needs can provide evidence to local policy makers that broadband is essential for community success. once the municipality sees the potential for social and economic development, it is more likely to support policies that stimulate broadband buildout. building strong local partnerships will set the stage for the development of a sustainable broadband initiative as the different stakeholders share perspectives that take into account a variety of necessary components. when the time comes to implement a strategy, not only will different perspectives have been included, the plan will have champions to speak for it: the government, isps, public and private agencies, and community members. it is important to know which constituents are already engaged in supporting community broadband initiatives and which should be tapped. the ultimate purpose in establishing broadband internet access in a community is to benefit the individual community members, thereby stimulating local economic development. key players need to represent agencies that recognize the individual voice. a 2004 study led by strover provides an example of the importance of engaging local community leaders and agencies in developing a successful broadband access project.13 the study looked at thirty-six communities that received state funding to establish community technology centers (ctc). it addressed the effective use and management of ctcs and called attention to the inadequacy of supplying the hardware without community support which found that of the 27 percent of adult americans who are not internet users, 33 percent report they are not interested in going online.10 that pew can report similar information five years after the wilhelm article identifies a barrier to equitable access that has not been adequately resolved. ■■ models for sustainable broadband availability in discussing broadband, the question of what constitutes broadband inevitably arises. gillett, lehr, and osoria, in “local government broadband initiatives,” offers a functional definition: “access is ‘broadband’ if it represents a noticeable improvement over standard dial-up and, once in place, is no longer perceived as the limiting constraint on what can be done over the internet.”11 while this definition works in relationship to dial-up, it is flexible enough to apply to all situations by focusing on “a noticeable improvement” and “no longer perceived as the limiting constraint” (added emphasis). ensuring sustainable broadband access necessitates anticipating future demand. short sighted definitions, applicable at a set moment in time, limit long-term viability of alternative solutions. devising a sustainable solution calls for careful scrutiny of alternative models, because the stakes are so high in the broadband debate. there are many different players involved in constructing information policies. this does not mean, however, that their perspectives are mutually exclusive. in debates with multiple perspectives, it is important to involve stakeholders who are aligned with the ultimate goal: assuring access to quality broadband to anyone going online. what is successful for one community may be entirely inappropriate in another; designing a successful system requires examining and comparing a range of scenarios. existing circumstances may predetermine a particular starting point, but one first step is to evaluate best practices currently in place in a variety of communities to come up with a plan that meets the unique criteria of the community in question. sustainable broadband solutions need to be developed with local constituents in mind and successful solutions will incorporate the realities of current and future local technologies and infrastructure as well as local, state, and federal information policies. presupposing that the goal is to provide the community with the best possible option(s) for quality broadband access, these are key considerations to take into account when devising the plan. in addition to the technological and infrastructure issues, within a community there will be a combination of ways people access the internet. there will be those who have home access, those who need public access, and those who do not seek access 190 information technology and libraries | december 2010 the current emphasis on universal broadband depends on selecting the best of the alternative plans according to carefully vetted criteria in order to develop a flexible and forward-thinking course of action. can we let people remain without access to robust broadband and the necessary skill set to use it effectively? no. as more and more resources critical to basic life tasks are accessible only online, those individuals that face challenges to going online will likely be socially and economically disadvantaged when compared to their online counterparts. recognition of this potential for intensifying digital divide is recognized in the federal communication commission’s (fcc) national broadband plan (nbp) released in march 2010.18 the nbp states six national broadband goals, the third of which is “every american should have affordable access to robust broadband service, and the means and skills to subscribe if they so choose.”19 research conducted for the recommendations in the nbp was comprehensive in scope including voices from industry, public interest, academia, and municipal and state government. responses to more than thirty public notices issued by the fcc provide evidence of wide concern from a variety of perspectives that broadband access should become ubiquitous if the united states is to be a competitive force in the twentyfirst century. access to essential information such as government, public safety, educational, and economic resources requires a broadband connection to the internet. it is incumbent on government officials, isps, and community organizations to share ideas and resources to achieve a solution for providing their communities with robust and sustainable broadband. it is not necessary to have all users up to par with the early adopters. there is not a one-size-fits-all approach to wanting to be connected, nor is there a one-size-fits-all solution to providing access. what is important is that an individual can go online via a robust, high-speed connection that meets that individual’s needs at that moment. what this means for finding solutions is ■■ there needs to be a range of solutions to meet the needs of individual communities; ■■ they need to be flexible enough to meet the evolving needs of these communities as applications and online content continue to change; and ■■ they must be sustainable for the long term so that the community is prepared to meet future needs that are as yet unknown. solutions to providing broadband internet access will be most successful when they are designed starting at the local level. community needs vary according to local demographics, geography, existing infrastructure, types of service providers, and how state and federal systems in place. users need a support system that highlights opportunities available via the internet and that provides help when they run into problems. access is more than providing the infrastructure and hardware. the potential users must also find content that is culturally relevant in an environment that supports local needs and expectations. strover found the most successful ctcs were located in places that “actively attracted people for other social and entertaining reasons.”14 in other words, the ctcs did not operate in a vacuum devoid of social context. successful adoption of the ctcs as a resource for information was dependent on the targeted population finding culturally relevant content in a supportive environment. an additional point made in the study showed that without strong community leadership, there was not significant use of the ctc even when placed in an already established community center.15 this has significant implications for what constitutes access as libraries plan broadband initiatives. investments in technology and a national commitment to ensure universal access to these new technologies in the 1990s provide the current policy framework. as suggested by wilhelm in 2003, to continue to move forward the national agenda needs to focus on updating policies to fit new information circumstances as they arise. today’s information policy debates should emphasize a similar focus. beyond accelerating broadband deployment into underserved areas, wilhelm suggests there needs to be support for training and content development that guarantees communities will actually use and benefit from having broadband deployed in their area.16 technology training and support for local agencies that provide the public with internet access, as well as opportunities for the individuals themselves, is essential if policies are going to actually lead to useful broadband adoption. individual and agency internet access and adoption require investment beyond infrastructure; they depend on having both culturally relevant content and the information literacy skills necessary to benefit from it. ■■ finding the right solution though it may have taken an economic crisis to bring broadband discussions into the living room, the result is causing renewed interest in a long-standing issue. many states have formed broadband task forces or councils to address the lack of adequate broadband access at the state level and, on the national front, broadband was a key component of the american recovery and reinvestment act of 2009.17 the issue changes as technologies evolve but the underlying tenet of providing people access to the information and resources they need to be productive members of society is the same. what becomes of generating collaborative systems for digital libraries | visser and ball 191 difficult to measure, these kinds of social and cultural capital are important elements in ongoing debates about uses and consequences of broadband access. an ongoing challenge for those interested in the social, economic, and policy consequences of modern information networks will be to keep up with changing notions of what it means to be connected in cyberspace.”20 the social contexts in which a broadband plan will be enacted influence the appropriateness of different scenarios and should help guide which ones are implemented. engaging a variety of stakeholders will increase the likelihood of positive outcomes as community members embrace the opportunities provided by broadband internet access. it is difficult, however, to anticipate the outcomes that may occur as users become more familiar with the resources and achieve a higher level of comfort with technology. ramirez states, the “unexpected outcomes” section of many evaluation reports tends to be rich with anecdotes . . . . the unexpected, the emergent, the socially constructed innovations seem to be, to a large extent, off the radar screen, and yet they often contain relevant evidence of how people embrace technology and how they innovate once they discover its potential.21 community members have the most to gain from having broadband internet access. including them will increase the community’s return on its investment as they take advantage of the available resources. ramirez suggests that “participatory, learning, and adaptive policy approaches” will guide the community toward developing communication technology policies that lead to a vibrant future for individuals and community alike.22 as success stories increase, the aggregation of local communities’ social and economic growth will lead to a net sum gain for the nation as a whole. ■■ the role of the library public libraries play an important role in providing internet access to their community members. according to a 2008 study, the public library is the only outlet for no-fee internet access in 72.5 percent of communities nationwide; in rural communities the number goes up to 82.0 percent.23 beyond having desktop or, in some cases, wireless access, public libraries offer invaluable user support in the form of technical training and locally relevant content. libraries provide a secondary community resource for other local agencies who can point their clients to the library for no-fee internet access. in today’s economy where anecdotal reports show an increase in library use, particularly internet use, the role of the public policies mesh with local ordinances. local stakeholders best understand the complex interworking of their community and are aware of who should be included in the decision-making process. including a local perspective will also increase the likelihood that as community needs change, new issues will be brought to the attention of policy makers and agencies who advocate for the individual community members. community agencies that already are familiar with local needs, abilities, and expectations are logical groups to be part of developing a successful local broadband access strategy. the library exemplifies a community resource whose expertise in local issues can inform information policy discussions on local, state, and federal levels. as a natural extension of library service, libraries offer the added value support necessary for many users to successfully navigate the internet. the library is an established community hub for informational resources and provides dedicated staff, technology training opportunities, and no-fee public access computers with an internet connection. libraries in many communities are creating locally relevant web-based content as well as linking to other community resources on their own websites. seeking a partnership with the local library will augment a community broadband initiative. it is difficult to appreciate the impacts of current information technologies because they change so rapidly there is not enough time to realistically measure the effects of one before it is mixed in with a new innovation. with web-based technologies there is a lag time between what those in the front of the pack are doing online and what those in the rear are experiencing. while there is general consensus that broadband internet access is critical in promoting social and economic development in the twenty-first century as is evidenced by the national purposes outlined in the nbp, there is not necessarily agreement on benchmarks for measuring the impacts. three anticipated outcomes of providing community access to broadband are ■■ civic participation will increase; ■■ communities will realize economic growth; and ■■ individual quality of life will improve. when a strategy involves significant financial and energy investments there is a tendency to want palpable results. the success of providing broadband access in a community is challenging to capture. to achieve a level of acceptable success it is necessary to focus on local communities and aggregate anecdotal evidence of incremental changes in public welfare and economic gain. acceptable success is subjective at best but can be usefully defined in context of local constituencies. referring to participation in the development of a vibrant culture, horrigan notes that “while inherently 192 information technology and libraries | december 2010 isolation. an individual must possess skills to navigate the online resources. as users gain an understanding of the potential personal growth and opportunities broadband yields, they will be more likely to seek additional online resources. by stimulating broadband use, the library will contribute to the social and economic health of the community. if the library is to extend its role as the information hub in the community by providing no-fee access to broadband to anyone who walks through the door, the local community must be prepared to support that role. it requires a commitment to encourage build out of appropriate technology necessary for the library to maintain a sustainable internet connection. it necessitates that local communities advocate for national information and communication policies that are pro-library. when public policy supports the library’s efforts, the local community benefits and society at large can progress. what if the library’s own technology needs are not met? the role of the library in its community is becoming increasingly important as more people turn to it for their internet access. without sufficient revenue, the library will have a difficult time meeting this additional demand for services. in turn, in many libraries increased demand for broadband access stretches the limit of it support for both the library staff and the patrons needing help at the computers. what will be the fallout from the library not being able to provide internet services the patrons desire and require? will there be a growing skills difference between people who adopt emerging technologies and incorporate them into their daily lives and those who maintain the technological status quo? what will the social impact be of remaining off line either completely or only marginally? can the library be the bridge between those on the edge, those in the middle, and those at the end? with a strong and well articulated vision for the future, the library can be the link that provides the community with sustainable broadband. ■■ conclusion the recent national focus on universal broadband access has provided an opportunity to rectify a lapse in effective information policy. whether the goal includes facilitating meaningful access continues to be more elusive. as government, organizations, businesses, and individuals rely more heavily on the internet for sharing and receiving information, broadband internet access will continue to increase in importance. following the status quo will not necessarily lead to more people having broadband access in the long run. the early adopters will continue to stimulate technological innovation which, in turn, will trickle down the ranks of the different user types. currently, library as a stable internet provider cannot be overestimated. to maintain its vital function, however, the library must also resolve infrastructure challenges of its own. because of the increased demand for access to internet resources, public libraries are finding their current broadband services are not able to support the demand of their patrons. the issues are two-fold: increased patron use means there are often neither sufficient workstations nor broadband speeds to meet patron demand. in 2008, about 82.5 percent of libraries reported an insufficient number of public workstations, and about 57.5 percent reported insufficient broadband speeds.24 to add to these already significant issues, the report indicates libraries are having trouble supporting the necessary information technology (it) because of either staff time constraints or the lack of a dedicated it staff.25 public libraries are facing considerable infrastructure management issues at a time when library use is increasing. overcoming the challenges successfully will require support on the local, state, and federal level. here is where the librarian, as someone trained to become inherently familiar with the needs of her local constituency and ethically bound to provide access to a variety of information resources, needs to insert herself into the debate. librarians need to be ahead of the crowd as the voice that assures content will be readily accessible to those who seek it. today, the elemental policy issue regarding access to information via the internet hinges on connectivity to a sustainable broadband network. to promote equitable broadband access, the librarian needs be aware of the pertinent information policies in place or under consideration, and be able to anticipate those in the future. additionally, she will need to educate local policy makers about the need for broadband in their community. in some circumstances, the librarian will need to move beyond her local community and raise awareness of community access issues on the state and federal level. the librarian is already able to articulate numerous issues to a variety of stakeholders and can transfer this skill to advocate for sustainable broadband strategies that will succeed in her local community. there are many strata of internet users, from those in the forefront of early adoption to those not interested in being online at all. the early adopters drive the market which responds by making resources more and more likely to be primarily available only online. as we continue this trend, the social repercussions increase from merely not being able to access entertainment and news to being unable to participate in the knowledge-based society of the twenty-first century. by folding in added value online access for the community, the library helps increase the likelihood that the community will benefit from broadband being available to the library patrons and by extension to the community as a whole. to realize the internet’s full potential, access to it cannot be provided in generating collaborative systems for digital libraries | visser and ball 193 community, the entire community benefits regardless of where and how the individuals go online. the effects of the internet are now becoming broadly social enough that there is a general awareness that the internet is not decoration on contemporary society but a challenge to it.28 being connected is no longer an optional luxury; to engage in the twenty-first century it is essential. access to the internet, however, is more than simple connectivity. successful access requires: an understanding of the benefits to going on line, technological comfort, information literacy, ongoing support and training, and the availability of culturally relevant content. people are at various levels of internet use, from those eagerly anticipating the next iteration of web-based applications to those hesitant to open an e-mail account. this user spectrum is likely to continue. though the starting point may vary depending on the applications that become important to the user in the middle of the spectrum, there will be those out in front and those barely keeping up. the implications of the pervasiveness of the internet are only beginning to be appreciated and understood. because of their involvement at the cutting edge of internet evolution, librarians can help lead the conversations. libraries have always been situated in neutral territory within their communities and closely aligned with the public good. librarians understand the perspective of their patrons and are grounded in their local communities. librarians can therefore advocate effectively for their communities on issues that may not completely be understood or even recognized as mattering. connectivity is an issue supremely important to the library as today access to the full range of information necessitates a broadband connection. libraries have carved out a role for themselves as a premier internet access provider in the continually evolving online culture. as noted by bertot, mcclure, and jaeger, the “role of internet access provider for the community is ingrained in the social perceptions of public libraries, and public internet access has become a central part of community perceptions about libraries and the value of the library profession.”29 in times of both economic crisis and technological innovation, there are many unknowns. in part because of these two juxtaposed events, the role of the public library is in flux. additionally, the network of community organizations that libraries link to is becoming more and more complex. it is a time of great opportunity if the library can articulate its role and frame it in relationship to broader society. evolving internet applications require increasing amounts of bandwidth and the trend is to make these bandwidth-heavy applications more and more vital to daily life. one clear path the library community can take however, the supply of internet resources is unevenly stimulating user demand and the unequal distribution of broadband access has greater potential for significant negative social consequences. staying the course and following a haphazard evolution of broadband adoption, may, in fact, renew valid concerns about a digital divide. without an intentional and coordinated approach to developing a broadband strategy, its success is likely to fall short of expectations. the question of how to ensure that internet content is meaningful requires instituting a plan on a very local level, including stakeholders who are familiar with the unique strengths and weaknesses of their community. strover, in her 2000 article the first mile, suggests connectivity issues should be viewed from a first mile perspective where the focus is on the person accessing the internet and her qualitative experience rather than from a last mile perspective which emphasizes isp, infrastructure, and market concerns.26 both perspectives are talking about the same physical section of the connection network: the piece that connects the user to the network. according to strover, distinguishing between the first mile and last mile perspectives is more than an arbitrary argument over semantics. instead, a first mile perspective represents a shift “in the values and priorities that shape telecommunications policy.”27 by switching to a first mile perspective, connectivity issues immediately take into account the social aspects of what it means to be online. who will bring this perspective to the table? and how will we ascertain what the best approach to supporting the individual voice should be? the first mile perspective is one the library is intimately familiar with as an organization that traditionally advocates for the first mile of all information policies. the library is in a key position in the connectivity debate because of its inclination to speak for the user and to be aware of the unique attributes and needs of its local community. as part of its mission, the library takes into account the distinctive needs of its user community when it designs and implements its services. a natural outgrowth of this practice is to be keenly aware of the demographics of the community at large. the library can leverage its knowledge and understanding to create an even greater positive impact on the social, educational, and economic community development made possible by broadband adoption. to extend the first mile perspective analogy, in the connectivity debate, the library will play the role of the middle mile: the support system that successfully connects the internet to the consumer. while the target populations for stimulating demand for broadband are really those in the second tier of users, by advocating for the first mile perspective, the library will be advocating for equitable information policies whose implementation has bearing on the early adopters as well. by stimulating demand for broadband within a 194 information technology and libraries | december 2010 initiatives,” 538. 12. ibid., 537–58.

role as the middle mile connecting the increasing breadth of internet resources to the general public. the broadband debate has moved out of the background of telecommunication policy and into the center of public attention. now is the moment that calls for an information policy advocate who can represent the end user while understanding the complexity of the other stakeholder perspectives. the library undoubtedly has its own share of stakeholders, but over time it is an institution that has maintained a neutral stance within its community, thereby achieving a unique ability to speak for all parties. those who speak for the library are able to represent the needs of the public, work with a diverse group of stakeholders, and help negotiate a sustainable strategy for providing broadband internet access. references and notes 1. lee rainie, “2.0 and the internet world,” internet librarian 2007, http://www.pewinternet.org/presentations/2007/20 -and-the-internet-world.aspx (accessed mar.

dawes information technology and libraries | september 2012 76 abstract the adoption of integrated library systems (ils) became prevalent in the 1980s and 1990s as libraries began or continued to automate their processes. these systems enabled library staff to work, in many cases, more efficiently than they had in the past. however, these systems were also restrictive—especially as the nature of the work began to change—largely in response to the growth of electronic and digital resources that they were not designed to manage. new library systems—the second (or next) generation—are needed to effectively manage the processes of acquiring, describing, and making available all library resources. this article examines the state of library systems today and describes the features needed in a next-generation library system. the authors also examine some of the next-generation library systems currently in development that purport to fill the changing needs of libraries. introduction since the late 1980s and early 1990s, the library automation system has gone from inception to rapid implementation to near ubiquitous adoption. but after two decades of changes in information technology, and especially in the last decade, the library has seen itself facing tremendous changes in terms of both resources and services it provides. on the resource side, print material and physical items are no longer dominant collections; electronic resources are fast outpacing physical materials to become the dominant library resources, especially in the academic and special libraries. in addition, many other digital format resources, such as digital collections, institutional repositories, and e-books have taken root. on the service front, library users— accustomed to immediate and instant searching, finding, and accessing information in the google age—demand more and more instant and easy access to library resources and services. but the library automation system, also called the integrated library system (ils), has not changed much for the past two decades. it finds itself uneasily handling the ever-changing library environment and workflow. library staff becomes ever more frustrated with the ils, noting its inadequacy in dealing with their daily jobs. library users are confused by the many interfaces and complexity of library applications and systems. it is obvious that we are at the tipping point for a dramatic change in the area of library automation systems. the library literature has been referring to these as second-generation library automation systems or next-generation library systems.1 two pillars of the second-generation library automation system are(1) it will manage the library resources in the comprehensive and unified way regardless of resource format and location; and (2) it will break away from the traditional ils models and build on the service oriented architecture (soa) model. yongming want (wangyo@tcnj.edu) is systems librarian for the college of new jersey library, ewing township, and trevor dawes (tdawes@princeton.edu) is access services & circulation librarian, princeton university libraries, princeton, new jersey. the next generation library system: a promise fulfilled? | wang and dawes 77 we are at the beginning of a new era of library automation systems. some library system vendors have realized the need to change and have started to develop and implement the secondgeneration library automation system. we believe that the concept and implementation of the new library automation system will catch on quickly among the all types of libraries. it will change how the library conducts its business and will benefit both library staff and users. literature review there is not much research literature on the subject to date. after more than a decade of library automation development and implementation, starting in the late 1990s, libraries have been facing the challenges ushered in by rapidly evolving internet and web 2.0 technologies in addition to the growing number of savvy web users. libraries found themselves lagging behind other sources (such as internet search engines) in meeting users’ information needs, and library staff members are generally frustrated by the lack of flexibility of traditional library systems. as early as 2007, marshall breeding pointed out that “as librarians continue to operate with sparse resources, performing ever more services with ever more diverse collections—but with no increases in staff—it’s more important than ever to have automation tools that provide the most effective assistance possible.”2 in his 2009 article, he deliberately says that “dissatisfaction with the current slate of ils products runs high. the areas of concern lie in their inability to manage electronic content and with their user interfaces that do not fare well against contemporary expectations of the web.”3 so what are the trends in libraries for the last decade in terms of library resources, collections, services, and resource discoveries? according to breeding, there are three trends: “1. increased digital collections; 2. changed expectations regarding interfaces; 3. shifted attitudes toward data and software.”4 andrew pace notes that “web-based content, licensed resources, born-digital documents, and institutionally significant digital collections emerged rapidly to overtake the effort required to maintain print collections, especially in academic libraries.”5 another noticeable trend in the library technology field is occurring along with a similar trend in the general information technology field, that is, the open-source software movement. as pace states, “open source software (oss) efforts such as the open archive initiative (oai), dspace, and koha—just to name a few, as an exhaustive list would overwhelm the reader—challenged commercial proprietary systems, not only for market share but often in terms of sophistication and functionality.”6 as for the infrastructure and features of the second-generation library automation system, both breeding and pace have their respective visions. breeding writes that “the next generation of library automation systems needs to be designed to match the workflows of today’s libraries, which manage both digital and print resources.”7 “one of the fundamental assumptions of the next generation library automation would involve a design to accommodate the hybrid physical and digital existence that libraries face today.”8 pace specifically requires that the next-generation library automation system should use the web as a platform to fulfill the notion of software-as-aservice (saas), or further, platform-as-a-service (paas). the technical advantages of such systems would include the ability to “1. develop, test, deploy, host, and maintain on the same integrated environment; 2. user experience without compromise; 3. build-in scalability, reliability, and information technology and libraries | september 2012 78 security; 4. build-in integration with web services and databases; 5. support collaboration; 6. deep application instrumentation.”9 also as early as october 2007, computers in libraries invited ellen bahr to survey a number of library technology experts regarding what features and functionality they want to see built into ilss soon. the experts included roy tennant, kristin antelman, ross singer, andrew pace, john blyberg, stephen abram, and h. frank cervone. they identified the following key functionality for future ilss: • direct, read-only access to data, preferably through an open source database management system like mysql. • a standard way to communicate with the ils, preferably through an application programming interface. • standards-compliant systems including better security and more complete documentation. • the ability to run the ils on hardware that the library selects and on servers that the library administers. • greater interoperability of systems, pertaining to the systems within the library (including components from vendors, open source communities, and homegrown systems) and beyond (enterprise-level systems such as courseware and university portals, and shared library systems such as oclc). • greater distinction between the ils (which needs to efficiently manage a library’s business processes) and the opac (which needs to be a sophisticated finding tool). • better user interfaces, making use of the most current technologies available and providing a single interface to all of the library’s holdings, regardless of format.10 four aspects of next-generation ils there are four distinguishing characteristics of the next-generation ils we believe are critical. they are comprehensive library resources management; a system based on service-oriented architecture; the ability to meet the challenge of new library workflow; and a next-generation discovery layer. comprehensive library resources management comprehensive library resources management requires that next-generation ilss should be able to manage all library materials regardless of format or location. current ilss are built around the traditional library practice of print collections and services designed around these collections, but the last ten to fifteen years have seen great shifts in both library collections and services. print and physical materials are no longer the dominant resources. actually, in many libraries, especially in academic and research libraries, the building of electronic and digital collections have taken a larger role in library collection development. the traditional ils has not been able to handle ever-growing electronic and digital resources—either in terms of their acquisition or management. therefore a variety of either commercial or open-source the next generation library system: a promise fulfilled? | wang and dawes 79 electronic resources management systems (erm systems) have been developed over the years to address this management gap, but two problems exist: first, most erm systems, whether commercial or open-source, have not been able to truly integrate the acquisition process into the acquisitions workflow of the current ils systems, causing a messy and redundant workflow for the library staff. in libraries where an erm is deployed, staff generally track workflows in both the erm and the ils. if the library’s workflows have not been revised, miscommunication between the traditional acquisitions staff and the electronic resources staff can cause confusion, delay, and may even lead to disruption of services to library patrons. second, erm systems, by design, don’t take current library workflows into account. while it is true that these resources may need to be processed differently, library staff generally are used to traditional processes and want systems that function in familiar ways. many libraries, particularly academic libraries, still have relatively large serials departments responsible for the management of print journals. some have only recently begun to develop the personnel and the skills required to manage the influx of electronic and digital resources. because of these problems with existing erm systems, it is important that the next-generation ilss fully integrate the key features of erm systems, enabling the library to streamline and efficiently manage resources and staff. full integration of e-resource management would not only include acquisitions functionality but also the ability to manage licenses—a critical component of e-resource management—and the ability to manage the various packages, databases, and vendors. describing and providing access to e-resources are two aspects of the e-resources management process. these two features of the erm system should also be integrated with the description and metadata management component of the next-generation ils. centrally managing the metadata of e-resources enables easier discovery of resources by library users and has the advantage of shifting some of the management workflow to the metadata (or cataloging) staff. system based on service-oriented architecture next-generation ilss should be designed based on service-oriented architecture (soa). what is soa? a service-oriented architecture (soa) is an architecture for building business applications as a set of loosely coupled distributed components linked together to deliver a well-defined level of service. these services communicate with each other, and the communication involves data exchange or service coordination. soa is based on web services. broadly, soa can be classified into two aspects: services and connections, described below. services: a service is a function or some processing logic or business processing that is welldefined, self-contained, and does not depend on the context or state of other services. an example of a service is loan processing services, which can be a self-contained unit for processing loan applications. another example is weather services, used to get weather information. any application on the network can use the services of the weather service to get the weather information for a local area or region. in the library field, an example of a well-defined service is a check-in or check-out service. information technology and libraries | september 2012 80 connections: connections are the links connecting these self-contained distributed services with each other. they enable client-to-services communication. in case of web services, simple object access protocol (soap) is frequently used to communicate between services. there are many benefits of soa in the next-generation ils. these include the ability to be platform independent, therefore allowing libraries to use the software and hardware of their choice. there is no threat of being locked in to a single vendor, as many libraries are now with their current ilss. soa also enables incremental development, deployment, and maintenance. the vendors can use the existing software (investment) and use soa to build applications without replacing existing applications. as breeding described, the potential of web services (soa) for libraries includes • real-time interaction between library-automation systems and business systems of a library’s parent organization; • real-time interaction between library-automation systems and library suppliers or other business partners; • blending of library services into campus or municipal portal environments; • insertion of library services and content into courseware-management systems or other learning environments; • blending of content from external sources into library interfaces; and • delivery of library services and content to library users through nontraditional channels. 11 meet the challenge of the new library workflow the library systems in use today are, in general, aging—most were developed at least ten to fifteen years ago. they have been updated with software patches and new releases, but they still demand that staff work in the manner in which the systems were originally designed. although changes in our library operations have been realized in many organizations, these systems have not been able to adequately adapt to how library staff now want to—or need to—operate. the inability to keep pace with the move from largely print to increasingly electronic resources in our libraries is one of the reasons our existing systems fail. copeland et al. present a stunning visual of the typical workflow involved in acquiring and making available an electronic resource in the print-based library management system.12 their graphic depicts five possible starting points, nine decision points, and close to twenty steps involved in the process. this process may not be typical, but it is illustrative of the complex nature of our new workflows that simply cannot be accommodated by existing ilss. as early as 1997, the sirsi corporation recognized the need to modify systems; they introduced workflows, which is designed to streamline library operations.13 workflows, which introduced a graphical user interface to the sirsi unicorn system, was intended to allow staff a certain amount of flexibility and customization, depending on the tasks they typically perform. the new systems that are being developed and deployed today promise even more flexibility and propose to enable staff to work more efficiently irrespective of the format of the material being processed. but these systems will require staff to think about workflows in entirely different ways. not only will the method used to perform tasks be different (now web-based, hosted services as the next generation library system: a promise fulfilled? | wang and dawes 81 opposed to client-server-based tools) but the functionality has been enhanced to be more efficient. we cannot say how these new systems will be welcomed or resisted by staff. nor can we say how much staff savings will be realized because these systems are still too new and have not yet been implemented on a wide enough scale for a thorough assessment. but they are at least starting to address the issue. on the one hand, they will open a new window for further study and exploration of how to shape the next-generation ilss to suit the new library workflow. on the other hand, the library will benefit by changing some of their out-of-date practices and workflows around the new system. next-generation discovery layer current library opacs, like the ilss themselves, are more than ten years old and generally have shown no improvement in search capability, navigability, or discovery. meanwhile, search technology has radically improved in the past decade. frustrations with the opacs’ limitations on the part of both librarians and library users eventually motivated many libraries to seek alternatives. libraries want to take advantage of the advances in search and discovery technology by implementing “nextgen” opacs or library discovery services. given the vast range of resources available in libraries—local print holdings, specialized databases, and commercial databases to name only a few—libraries want a service that would make as many of them as discoverable as possible. the ideal system would have a unified search interface with a single search box, but with relevance ranking, faceted search, social tagging of records, persistent links to records, rss feeds for searches, and the ability to easily save searches or export selected records to standard bibliographic management software programs. the ideal system would also integrate with the library’s opac, overlaying its current interface with a more nimble and navigable interface that still allows real-time circulation status and provides as much support as possible for foreign language fonts. it would also be as customizable as possible. numerous options for discovery currently exist, and these include summon from serials solutions, primo from ex libris, worldcat local from oclc, ebsco discovery service, and encore from innovative interfaces. as these services are not the focus of this article, they will not be discussed in detail, but the next-generation ilss should have the ability to integrate seamlessly with these discovery services. analysis of two examples 1. alma development in early 2009, ex libris (owner of aleph and voyager) began discussions with several institutions (boston college, princeton university, and katholieke universiteit leuven; purdue university joined later) to develop what they then termed the unified resource management system (urm). the urm was to replace the existing ilss and the subsequent add-ons that provided functionality not inherently available, such as the electronic resources management (erm) tools. the “backend” operations would also be de-coupled from the user interface as described elsewhere in this paper. information technology and libraries | september 2012 82 through a series of in-person and online meetings with the development partners, ex libris staff developed the conceptual framework and functional requirements for the urm (later named alma) and began development of the product. alma was delivered to the partners in a series of releases, each with more functionality, and the feedback was used to enhance or further develop the product. alma uses the concept of a shared metadata repository (the metadata management system) to which libraries would contribute, through which records would be shared, and from which records would be downloaded and edited with local information. selection and acquisitions functions would be integrated not only within alma, but within the discovery layer to allow patrons, as well as staff, the ability to suggest items for addition to the library’s holdings. with “smart fulfillment,” the workflows for delivering materials to patrons will also be seamless.14 one of the major changes planned for alma is the ability to manage the types of resources that cannot be effectively managed in current ilss—specifically electronic and digital resources. these resources are currently managed with the use of add-on products that interact with varying degrees of success with the ilss. this lack of integration has been a source of frustration for library staff, particularly as library electronic and digital collections continue to steadily grow. the development partners have presented extensively at various conferences about the development process and have been mostly positive about the product. dawes and lute described princeton university’s participation in a presentation at the 2011 acrl conference in philadelphia.15 at princeton, an executive committee was created to oversee that partner’s process. other staff members were then involved in testing each of the partner releases as the functionality increased and was made available to them. the princeton university team then provided feedback to ex libris via regular telephone calls, after which they would see changes based on their feedback, or a status update from ex libris about the particular issue reported. the staff members at princeton believe that their participation in the development of alma has given them an opportunity to closely examine their workflows to see where efficiencies can be made. 2. kuali ole project in 2008 a group of nine libraries formed the open library environment (ole) project, later called kuali ole. kuali is a community of higher education institutions that came together to build enterprise-level and open-source applications for the higher education community. these systems include some core applications such as kuali financial system, kuali people management, and other campus-wide applications. the kuali ole is its most recent endeavor. the purpose of the kuali ole project is to build an enterprise-level, open-source, and next-generation ils. the goal of kuali ole, taken from its website (http://kuali.org/ole), is to “develop the first system designed by and for academic and research libraries for managing and delivering intellectual information.” there are six principal objectives of the project: • to be built, owned, governed by the academic and research library community • to supports the wide range of resources and formats of scholarly information • to interoperate and integrate with other enterprise and network-based systems the next generation library system: a promise fulfilled? | wang and dawes 83 • to support federation across projects, partners, consortia, and institutions • to provide workflow design and management capabilities • to provides information management capabilities to nonlibrary efforts the funding is provided by a contribution from the andrew w. mellon foundation and the nine partner institutions. kuali ole will be built based on the soa model, on top of the kuali middleware application, kuali rice, the core component of the kuali suite of applications. kuali rice “provides an enterprise class middleware suite of integrated products that allows for applications to be built in an agile fashion. this enables developers to react to end user business requirements in an efficient and productive manner, so that they can produce high quality business applications.”16 version 1.0 of kuali ole is scheduled to be released to the public in december 2012. a stepping and testing version (0.3) was released in november 2011, which covers some core acquisitions features such as “select” and “acquire” processes. we believe that the kuali ole software will not only provide an alternative solution of the ils for academic and research libraries, but will change the way the library conducts its business, and will also have implications for staffing. these changes will result from the comprehensive management of library materials and resources, and the system’s interoperability with other college-level enterprise applications. conclusion after about two decades of library automation system history, both libraries and vendors have begun to realize that a revolutionary change is needed in designing and developing the nextgeneration ils. the system, built on the model of soa, should enable the library to comprehensively and effectively manage all library resources and collections, should accommodate a more flexible library workflow, and should enable the library to provide better services to library users. it is encouraging to see that, in both the commercial and open-source arenas, concrete steps are being taken to develop these systems that will manage all library resources. alma and kuali ole are but two of the next-generation ilss in development. in 2011, serials solutions announced their intent to develop a system using the same principles as described. so have innovative interfaces and oclc, the latter of which has already released an early version of their product to some institutions. since these products are still in development and implementation is not yet widespread, their success in meeting the needs of the library community is still to be seen. references 1. marshall breeding, “next generation library automation: its impact

 context,  the  focus  of  usability  tests  has  remained  on  the  search  interface  rather   than  the  discovery  process  for  users.  the  informal  site-­‐  and  context  specific  usability  tests  have   offered  little  to  test  the  rigor  of  the  discovery  layers  against  the  user  goals,  motivations  and  workflow   they  have  been  designed  to  support.  this  study  proposes  hierarchical  task  analysis  (hta)  as  an   important  complementary  evaluation  method  to  usability  testing  of  discovery  layers.  relevant   literature  is  reviewed  for  the  discovery  layers  and  the  hta  method.  as  no  previous  application  of  hta   to  the  evaluation  of  discovery  layers  was  found,  this  paper  presents  the  application  of  hta  as  an   expert  based  and  workflow  centered  (e.g.,  retrieving  a  relevant  book  or  a  journal  article)  method  to   evaluating  discovery  layers.  purdue  university’s  primo  by  ex  libris  was  used  to  map  eleven  use  cases   as  hta  charts.  nielsen’s  goal  composition  theory  was  used  as  an  analytical  framework  to  evaluate   the  goal  charts  from  two  perspectives:  a)  users’  physical  interactions  (i.e.,  clicks),  and  b)  user’s   cognitive  steps  (i.e.,  decision  points  for  what  to  do  next).  a  brief  comparison  of  hta  and  usability  test   findings  is  offered  as  a  way  of  conclusion.   introduction   discovery  layers  are  relatively  new  third  party  software  components  that  offer  google-­‐like  web-­‐ scale  search  interface  for  library  users  to  find  information  held  in  the  library  catalo  and  beyond.   libraries  are  increasingly  utilizing  these  to  offer  a  better  user  experience  to  their  patrons.  while   popular  in  application,  the  discussion  about  discovery  layer  implementation  and  evaluation   remains  limited.  [1][2]     a  majority  of  reported  case  studies  discussing  discovery  layer  implementations  are  based  on   informal  usability  tests  that  involve  a  small  sample  of  users  in  a  specific  context.  the  resulting  data   sets  are  often  incomplete  and  the  scenarios  are  hard  to  generalize.[3]  discovery  layers  have  a   number  of  technical  advantages  over  the  traditional  federated  search  and  cover  a  much  wider   range  of  library  resources.  however,  they  are  not  without  limitations.  questions  have  remained   scarce  about  the  workflow  of  discovery  layers  and  how  well  they  help  users  achieve  their  goals.     merlen  prommann  (mpromann@purdue.edu)  is  user  experience  researcher  and  designer,   purdue  university  libraries.  tao  zhang  (zhan1022@purdue.edu)  is

 thomsett-­‐scott  and  patricia  e.  reese1  offered  an  extensive  overview  of  the  literature   discussing  the  disconnect  between  what  the  library  websites  offer  and  what  their  users  would   like.[1]  on  the  one  hand,  library  directors  deal  with  a  great  variety  of  faculty  perceptions,  in  terms   of  what  the  role  of  library  is  and  how  they  approach  research  differently.  the  ithaka  s+r  library   survey  of  not-­‐for  profit  four-­‐year  academic  institutions  in  the  us  suggests  a  real  diversity  of   american  academic  libraries  as  they  seek  to  develop  services  with  sustained  value.[4]  for  the   common  library  website  user,  irrelevant  search  results  and  unfamiliar  library  taxonomy  (e.g.  call   numbers,  multiple  locations,  item  formats,  etc.)  are  two  most  common  gaps.[3]  michael  khoo  and   catherine  hall  demonstrated  how  users,  primarily  college  students,  have  become  so  accustomed   to  the  search  functionalities  on  the  internet  that  they  are  reluctant  to  use  library  websites  for  their   research.[5]  no  doubt,  the  launch  of  google  scholar  in  2005  was  another  driver  for  librarians  to   move  from  the  traditional  federated  searching  to  something  faster  and  more  comprehensive.[1]   while  literature  encouraging  google-­‐like  search  experiences  is  abundant,  khoo  and  hall  have   warned  designers  to  not  take  users’  preferences  towards  google  at  face  value.  they  studied  users’   mental  models,  defining  it  as  “a  model  that  people  have  of  themselves,  others,  the  environment,   and  the  things  with  which  they  interact,  such  as  technologies,”  and  concluded  that  users  often  do   not  understand  the  complexities  of  how  search  functions  actually  work  or  what  is  useful  about   them.[5]     a  more  systematic  examination  of  the  tasks  that  discovery  layers  are  designed  to  support  is   needed.  this  paper  introduces  hierarchical  task  analysis  (henceforth  hta)  as  an  expert  method  to   evaluate  discovery  layers  from  a  task-­‐oriented  perspective.  it  aims  to  complement  usability   testing.  for  more  than  40  years,  hta  has  been  the  primary  methodology  to  study  systems’  sub-­‐ goal  hierarchies  for  it  presents  the  opportunity  to  provide  insights  into  key  workflow  issues.  with   expertise  in  applying  hta  and  being  frequent  users  of  the  purdue  university  libraries  website  for   personal  academic  needs,  we  mapped  user  tasks  into  several  flow  charts  based  on  three  task   scenarios:  (1)  finding  an  article,  (2)  finding  a  book,  and  (3)  finding  an  ebook.  jackob  nielsen’s   “goal  composition”  heuristics:  generalization,  integration  and  user  control  mechanisms[6]  were   used  as  an  analytical  framework  to  evaluate  the  user  experience  of  an  ex  libris  primo®  discovery   layer  implemented  at  purdue  university  libraries.  the  goal  composition  heuristics  focus  on   multifunctionality  and  the  idea  of  servicing  many  possible  user  goals  at  once.  for  instance,   generalization  allows  users  to  use  one  feature  on  more  objects.  integration  allows  each  feature  to   be  used  in  combination  with  other  facilities.  control  mechanisms  allow  users  to  inspect  and   amend  how  the  computer  carries  out  the  instructions.  we  discussed  the  key  issues  with  other   library  colleagues  to  meet  nielsen’s  five  expert  rule  and  avoid  loss  in  the  quality  of  insights.[7]   nielsen  studied  the  value  of  participant  volume  in  usability  tests  and  concluded  that  after  the  fifth   user  researchers  are  wasting  their  time  by  observing  the  same  findings  and  not  learning  much   new.  a  comparison  to  usability  study  findings,  as  presented  by  fagan  et  al,  is  offered  as  a  way  of   conclusion.[3]       information  technology  and  libraries  |  march  2015   79   related  work     discovery  layers   the  traditional  federated  search  technology  offers  the  overall  benefit  of  searching  many  databases   at  once.[8][1]  yet  it  has  been  known  to  frustrate  users,  as  they  often  do  not  know  which  databases   to  include  in  their  search.  emily  alling  and  rachel  naismith  aggregated  common  findings  from  a   number  of  studies  involving  the  traditional  federated  search  technology.[9]  besides  slow  response   time,  other  key  causes  of  frustrating  inefficiency  were:  limited  information  about  search  results,   information  overload  due  to  the  lack  of  filters,  and  the  fact  that  results  were  not  ranked  in  order  of   relevance  (see  also  [2][1]).   new  tools,  termed  as  “discovery,”  “discovery  tools,”[2][10]  “discovery  layers’”  or  “next  generation   catalogs,”[11]  have  become  increasingly  popular  and  have  provided  the  hope  of  eliminating  some   of  the  issues  with  traditional  federated  search.  generally,  they  are  third  party  interfaces  that  use   pre-­‐indexing  to  provide  speedy  discovery  of  relevant  materials  across  millions  of  records  of  local   library  collections,  from  books  and  articles,  to  databases  and  digital  archives.  furthermore,  some   systems  (e.g.,  ex  libris  primo  central  index)  aggregate  hundreds  of  millions  of  scholarly  e-­‐ resources,  including  journal  articles,  e-­‐books,  reviews,  legal  documents  and  more  that  are   harvested  from  primary  and  secondary  publishers  and  aggregators,  and  from  open-­‐access   repositories.  discovery  layers  are  projected  to  help  create  the  next  generation  of  federated  search   engines  that  utilize  a  single  search  index  of  metadata  to  search  the  rising  volume  of  resources   available  for  libraries.[2][11][10][1]    while  not  systematic  yet,  results  from  a  number  of  usability   studies  on  these  discovery  layers  point  to  the  benefits  they  offer.     the  most  noteworthy  benefit  of  a  discovery  layer  is  its  seemingly  easy  to  use  unified  search   interface.  jerry  caswell  and  john  d.  wynstra  studied  the  implementation  of  ex  libris  metalib   centralized  indexes  based  on  the  federated  search  technology  at  the  university  of  northern  iowa   library.[8]  they  confirmed  how  the  easily  accessible  unified  interface  helped  users  to  search   multiple  relevant  databases  simultaneously  and  more  efficiently.  lyle  ford  concluded  that  the   summon  discovery  layer  by  serials  solutions  fulfilled  students’  expectations  to  be  able  to  search   books  and  articles  together.[12]  susan  johns-­‐smith  pointed  out  another  key  benefit  to  users:   customizability.[10]  the  summon  discovery  layer  allowed  users  to  determine  how  much  of  the   machine-­‐readable  cataloging  (marc)  record  was  displayed.  the  study  also  confirmed  how  the   unified  interface,  aligning  the  look  and  feel  among  databases,  increased  the  ease  of  use  for  end-­‐ users.  michael  gorrell  described  how  one  of  the  key  providers,  ebsco,  gathered  input  from  users   and  considered  design  features  of  popular  websites,  to  implement  new  technologies  to  the   ebscohost  interface.[13]  some  of  the  features  that  ease  the  usability  of  ebscohost  are  a  dynamic   date  slider,  an  article  preview  hover,  and  expandable  features  for  various  facets,  such  as  subject   and  publication.[2]     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang       80   another  key  benefit  of  discovery  systems  is  the  speed  of  results  retrieval.  the  primo  discovery   layer  by  ex  libris  has  been  complimented  for  its  ability  to  reduce  the  time  it  takes  to  conclude  a   search  session,  while  maximizing  the  volume  of  relevant  results  per  search  session.[14]  it  was   suggested  that  in  so  doing  the  tool  helps  introduce  users  to  new  content  types.  yuji  tosaka  and   cathy  weng  reported  how  records  with  richer  metadata  tend  to  be  found  more  frequently  and   lead  to  more  circulation.[15]  similarly,  luther  and  kelly  reported  an  increase  in  overall  downloads,   while  the  use  of  individual  databases  decreased.[16]  these  studies  point  to  the  trend  of  an   enhanced  distribution  of  discovery  and  knowledge.     with  the  additional  metadata  of  item  records,  however,  there  is  also  the  increased  likelihood  of   inconsistencies  across  databases  that  are  brought  together  in  a  centralized  index.  a  study  by   graham  stone  offered  a  comprehensive  report  on  the  implementation  process  of  the  summon   discovery  layer  at  the  university  of  huddersfield,  highlighting  major  inconsistences  in  cataloging   practices  and  the  difficulties  it  caused  in  providing  consistent  journal  holdings  and  titles.[17]  this   casts  shadows  on  the  promise  of  better  findability.     jeff  wisniewski[18]  and  williams  and  foster[2]  are  among  the  many  who  espouse  discovery   layers  as  a  step  towards  a  truly  single  search  function  that  is  flexible  while  allowing  needed   customizability.  these  new  tools,  however,  are  not  without  their  limitations.  the  majority  of   usability  studies  reinforce  similar  results  and  focus  on  the  user  interface.  fagan  et  al,  for  example,   studied  the  usability  of  ebsco  discovery  service  at  james  madison  university  (jmu).  while  most   tasks  were  accomplished  successfully,  the  study  confirmed  previous  warnings  that  users  do  not   understand  the  complexities  of  search  and  identified  several  interface  issues:  (1)  users  desire   single  search,  but  willingly  use  multiple  options  for  search,  (2)  lack  of  visibility  for  the  option  to   sort  search  results,  and  (3)  the  difficulty  in  finding  journal  articles.[3]     yang  and  wagner  offer  one  case  where  the  aim  was  to  evaluate  discovery  layers  against  a  check-­‐ list  of  12  features  that  would  define  a  true  ‘next  generation  catalogue’:     (1)  single  point  of  entry  to  all  library  information,     (2)  state-­‐of-­‐the-­‐art  web  interface  (e.g.  google  and  amazon),     (3)  enriched  content  (e.g.  book  cover  images,  ratings  and  comments),     (4)  faceted  navigation  for  search  results,     (5)  simple  keyword  search  on  every  page,     (6)  more  precise  relevancy  (with  circulation  statistics  a  contributing  factor),     (7)  automatic  spell  check,     (8)  recommendations  to  related  materials  (common  in  commercial  sites,  e.g.  amazon),     (9)  allowing  users  to  add  data  to  records  (e.g.  reviews),       information  technology  and  libraries  |  march  2015   81   (10)  rss  feeds  to  allow  users  to  follow  top  circulating  books  or  topic  related  updates  in  the   library  catalogue,     (11)  links  to  social  networking  sites  to  allow  users  to  share  their  resources,     (12)  stable  url’s  that  can  be  easily  copied,  pasted  and  shared.  [11]     they  used  this  list  to  evaluate  seven  open  source  and  ten  proprietary  discovery  layers,  revealing   how  only  a  few  of  them  can  be  considered  true  ‘next  generation  catalogs’  supporting  the  users’   needs  that  are  common  on  the  web.  all  of  the  tools  included  in  their  study  missed  precision  in   retrieving  relevant  search  results,  e.g.  based  on  transaction  data.  the  authors  were  impressed   with  open  source  discovery  layers  libraryfind  and  vufind,  which  had  10  of  the  12  features,   leaving  vendors  of  proprietary  discovery  layers  ranking  lower  (see  figure  1).     figure  1.  17  discovery  layers  (x-­‐axis)  were  evaluated  against  a  checklist  of  12  features  expected  of   the  next  generation  catalogue  (y-­‐axis)   yang  and  wagner  theorized  that  the  relative  lack  of  innovation  among  commercial  discovery   layers  is  due  to  practical  reasons:  vendors  create  their  new  discovery  layers  to  run  alongside  older   ones,  rather  than  attempting  to  alter  the  proprietary  code  of  the  integrated  library  system’s  (ils)   online  public  access  catalog  (opac).  they  pointed  to  the  need  for  “libraries,  vendors  and  the  open   source  community  […]  to  cooperate  and  work  together  in  a  spirit  of  optimism  and  collegiality  to   make  the  true  next  generation  catalogs  a  reality”.[11]  at  the  same  time,  the  university  of  michigan   article  discovery  working  group  reported  on  vendors’  being  more  cooperative  and  allowing   coordination  among  products,  increasing  the  potential  of  web-­‐scale  discovery  services.[19]  how

      82   challenge.  in  this  study,  we  propose  hta  as  a  prospectively  helpful  method  to  evaluate  user   workflow  through  these  increasingly  complex  products.       hierarchical  task  analysis   with  roots  in  tylorism*,  industrial  psychology  and  system  processes,  task  analyses  continue  to   offer  valuable  insights  into  the  balance  of  efficiency  and  effectiveness  in  human-­‐computer   interaction  scenarios  [20][21].  historically,  frank  and  lillian  gilbreth  (1911)  set  forth  the   principle  of  hierarchical  task  analysis  (hta),  when  they  broke  down  and  studied  the  individual   steps  involved  in  laying  bricks.  they  reduced  the  brick  laying  process  from  about  18  movements   down  to  four  (in  [21]).  but,  it  was  john  annett  and  keith  d.  duncan  (1967)  who  introduced  hta  as   a  method  to  better  evaluate  the  personnel  training  needs  of  an  organization.  they  used  it  to  break   apart  behavioral  aspects  of  complex  tasks  such  as  planning,  diagnosis  and  decision-­‐making  (see   in[22][21]).     hta  helps  break  users  goals  into  subtasks  and  actions,  usually  in  a  visual  form  of  a  graphic  chart.   it  offers  a  practical  model  for  goal  execution,  allowing  designers  to  map  user  goals  to  the  system’s   varying  task  levels  and  evaluate  their  feasibility  [23].  in  so  doing,  hta  offers  the  structure  with   which  to  learn  about  tasks  and  highlight  any  unnecessary  steps  and  potential  errors  that  might   occur  during  a  task  performance  [24][25],  whether  cognitive  or  physical.  its  strength  lies  in  its   dual  approach  to  evaluation:  on  the  one  hand,  user  interface  elements  are  mapped  at  an  extremely   low  and  detailed  level  (to  individual  buttons),  while  on  the  other  hand,  each  of  these  interface   elements  gets  mapped  to  user’s  high-­‐level  cognitive  tasks  (the  cognitive  load).  this  informs  a   rigorous  design  approach,  where  each  detail  accounts  for  the  high-­‐level  user  task  it  needs  to   support.     the  main  limitation  of  classical  hta  is  its  system-­‐centric  focus  that  does  not  account  for  the  wider   context  the  tasks  under  examination  exists  in.  the  field  of  human-­‐computer  interaction  has  shifted   our  understanding  of  cognition  from  an  individual  information  processing  model  to  a  networked   and  contextually  defined  set  of  interactions,  where  the  task  under  analysis  is  no  longer  confined  to   a  desktop  but  “extends  into  a  complex  network  of  information  and  computer-­‐mediated  interactions”   [26].  the  task  step  focused  hta  does  not  have  the  ability  to  account  for  the  rich  social  and   physical  contexts  that  the  increasingly  mediated  and  multifaceted  activities  are  embedded  in.  hta   has  been  reiterated  with  additional  theories  and  heuristics,  so  as  to  better  account  for  the   increasingly  more  complete  understanding  of  human  activity.       advanced  task  models  and  analysis  methods  have  been  developed  based  on  the  principle  of  hta.   stuart  k.  card,  thomas  p.  moran  and  allen  newell  [27]  proposed  an  engineering  model  of  human   performance  –  goms  (goals,  operators,  methods,  and  selection)  –  to  map  how  task  environment   features  determine  what  and  when  users  know  about  the  task  [20].  goms  have  been  expanded  to   cope  with  rising  complexities  (e.g.  [28][29][30]),  but  the  models  have  become  largely  impractical                                                                                                                             *  tylorism  is  the  application  of  scientific  method  to  the  analysis  of  work,  so  as  to  make  it  more  efficient  and  cost-­‐effective.  modern  task     information  technology  and  libraries  |  march  2015   83   in  the  process  [20].  instead  of  simplistically  suggesting  cognitive  errors  are  due  to  interface  design,   cognitive  task  analysis  (cta)  attempts  to  address  the  underlying  mental  processes  that  most   often  give  rise  to  errors  [24].  given  the  lack  of  our  structural  understanding  about  cognitive   processes,  the  analysis  of  cognitive  tasks  has  remained  problematic  to  implement  [20][31].   activity  theory  models  people  as  active  decision  makers  [20].  it  explains  how  users  convert  goals   into  a  set  of  motives  and  how  they  seek  to  execute  those  motives  as  a  set  of  interactions  in  a  given   situational  condition.  these  situational  conditions  either  help  or  prevent  the  user  from  achieving   the  intended  goal.  activity  theory  is  beginning  to  offer  a  coherent  foundation  to  account  for  the   task  context  [20],  but  it  has  yet  to  offer  a  disciplined  set  of  methods  to  execute  this  theory  in  the   form  of  a  task  analysis.     even  though  task  analyses  have  seen  much  improvement,  adaptation  and  usage  in  its  near-­‐40-­‐ year-­‐long  existence  and  its  core  benefit  –  aiding  an  understanding  of  the  tasks  users  need  to   perform  to  achieve  their  desired  goals  –  have  remained  the  same.  until  activity  theory,  cla  and   other  contextual  approaches  are  developed  into  more  readily  applicable  analysis  frameworks,   classical  hta  with  the  additional  layers  of  heuristics  guiding  the  analysis  remains  the  practical   option  [21].  nielsen’s  goal  composition  [6]  offers  one  such  set  of  heuristics  applicable  for  the  web   context.  it  presents  usability  concepts  such  as  reuse,  multitasking,  automated  use,  recovering  and   retrieving,  to  name  a  few,  so  as  to  systematically  evaluate  the  hta  charts  representing  the   interplay  between  an  interface  and  the  user.     utility  of  hta  for  evaluating  discovery  layers     usability  testing  has  become  the  norm  in  validating  the  effectiveness  and  ease  of  use  of  library   websites.  yet,  thirteen  years  ago,  brenda  battleson,  austin  booth  and  jane  weintrop  [32]   emphasized  the  need  to  support  user  tasks  as  the  crucial  element  to  user-­‐centered  design.  in   comparison  to  usability  testing,  hta  offers  a  more  comprehensive  model  for  the  analysis  of  how   well  discovery  layers  support  users’  tasks  in  the  contemporary  library  context.  considering  the   strengths  of  the  hta  method  and  the  current  need  for  vendors  to  simplify  the  workflows  in  the   increasingly  complex  systems,  it  is  surprising  that  hta  has  not  yet  been  applied  to  the  evaluation   of  discovery  layers.     this  paper  introduces  hierarchical  task  analysis  (hta)  as  a  solution  to  systematically  evaluate   the  workflow  of  discovery  layers  as  a  technology  that  helps  users  accomplish  specific  tasks,  herein,   retrieving  relevant  items  from  the  library  catalog  and  other  scholarly  collections.  nielsen’s  [6]   goal  composition  heuristics,  designed  to  evaluate  usability  in  the  web  context,  is  used  to  guide  the   evaluation  of  the  user  workflow  via  the  hta  task  maps.  as  a  process  (vs.  context)  specific   approach,  hta  can  help  achieve  a  more  systematic  examination  of  the  tasks  discovery  layers   should  support,  such  as  finding  an  article,  a  book  or  an  ebook,  and  help  vendors  coordinate  to   achieve  the  full  potential  of  web-­‐scale  discovery  services.       applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang

 january  2013  (figure  2)  to  serve  the  growing  student  and  faculty  community.  its   3.6  million  indexed  records  are  visited  over  1.1  million  times  every  year.  roughly  34%  of  these   visits  are  to  electronic  books.  according  to  sharon  q.  yang  and  kurt  wagner  [11],  who  studied  17   different  discovery  layers,  primo  ranked  the  best  among  the  commercial  discovery  layer  products,   coming  fourth  after  the  open  source  tools  library  find,  vufind,  and  scriblio  in  the  overall  rankings.   we  will  evaluate  how  efficiently  and  effectively  the  primo  search  interface  supports  users’  of  the   purdue  libraries  tasks.         figure  2.  purdue  library  front  page  and  search  box   based  on  our  three  year  experience  of  user  studies  and  usability  testing  of  the  library  website,  we   identified  finding  an  article,  a  book  and  an  ebook  as  the  three  major  representative  scenarios  of   purdue  library  usage.  to  test  how  primo  helps  its  users  and  how  many  cognitive  steps  it  requires   of  them,  each  of  the  three  scenarios  were  broken  into  three  or  four  specific  case  studies.  the  case   studies  were  designed  to  account  for  the  different  availability  categories  present  in  the  current   primo  system,  e.g.  ‘full  text  available’,  ‘partial  availability’,  ‘restricted  access’  or  ‘no  access’.  this  is   because  the  different  availabilities  present  users  with  different  possible  frustrations  and  obstacles     information  technology  and  libraries  |  march  2015   85   to  task  accomplishment.  this  system-­‐design  perspective  could  offer  a  comparable  baseline  for   discovery  layer  evaluation

 book  is  not  shown  in  search  results.  possible  option  is  to  use  uborrow  or  ill.   it  is  generally  accepted  that  hta  is  not  a  complex  analysis  method,  but  since  it  offers  general   guiding  principles  rather  than  a  rigorous  step-­‐by-­‐step  guide,  it  can  be  tricky  to  implement   [24][20][21][23].  both  authors  of  this  study  have  expertise  in  applying  hta  and  are  frequent   users  of  the  purdue  library’s  website.  we  are  familiar  with  the  library’s  commonly  reported   system  errors;  however,  all  of  our  case  studies  result  from  a  randomized  topic  search,  not  from   specific  reported  items.  to  achieve  consistent  hta  charts  one  author  carried  out  the  identified   use-­‐cases  on  a  part-­‐time

method  was  preferred  (figure  2).  each  analysis  started  with  the  establishment  of  sub-­‐goals,  such   as  ‘browse  the  library  website’  and  ‘retrieve  the  article’,  and  followed  with  the  identification  of   individual  small  steps  that  make  the  sub-­‐goal  possible,  e.g.  ‘press  search’  and  ‘click  on  2,  to  go  to   page  2’  (figures  3-­‐5).  then,  additional  iterations  were  made  to  include:  (1)  cognitive  steps,  where     information  technology  and  libraries  |  march  2015   87   users  need  to  evaluate  the  screen  in  order  to  take  the  next  step  (e.g.  identifying  the  correct  url  to   open  from  the  initial  results  set),  and  (2)  capture  cognitive  decision  points  between  multiple   options  for

 decision  flow  chart,  the  original  hierarchical  number  scheme  for  hta  that   requires  every  sub-­‐goal  to  be  uniquely  numbered  with  an  integer  in  numerical  sequence  [21],  was   strictly  followed.  visual  (screen  captures)  and  verbal  notes  on  efficient  and  inefficient  design   factors  were  taken  during  the  hta  mapping  process  and  linked  directly  to  the  tasks  they  applied   to.  steps,  where  interface  design  guided  the  user  to  the  next  step,  were  marked  ‘fluent’  with  a   green  tick  (figures  3  and  4).  steps  that  were  likely  to  mislead  users  from  the  optimal  path  to  item   retrieval  and  were  a  burden  to  user’s  workflow  were  marked  with  a  red  ‘x’  (see  figures  4  and  5).   one  major  advantage  of  the  diagram  format  is  its  visual  and  structural  representation  of  sub-­‐goals   and  their  steps  in  a  spatial  manner  (see  figures  2-­‐5).  this  is  useful  for  gaining  a  quick  overview  of   the  workflow  [21].   when  exactly  to  stop  the  analysis  has  remained  undefined  for  hta  [21].  it  is  at  the  discretion  of   the  analyst  to  evaluate  if  there  is  the  need  to  re-­‐describe  every  sub-­‐goal  down  to  the  most  basic   level,  or  whether  the  failure  to  perform  that  sub-­‐goal  is,  in  fact,  consequential  to  the  study  results.   we  decided  to  stop  evaluation  at  the  point  where  the  user  located  (a  shelf  number  or  reserve  pick   up  number)  or  received  the  sought  item  via  download.  furthermore,  steps  that  were  perceived  as   possible  when  impossible  in  actuality  were  transcribed  into  the  diagrams.  article  scenario  case  1   offers  an  example:  once  the  desired  search  result  was  identified,  its  green  dot  for  ‘full  text  available’     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang       90   was  likely  to  be  perceived  as  clickable,  when  in  actuality  it  was  not.  the  user  is  required  to  click  on   the  title  or  open  the  tab  ‘find  online’  to  access  the  external  digital  library  and  download  the   desired  article  (see  figure  7).       figure  7.  article  scenario  (case1)  two  search  results,  where  green  'full  text  available'  may  be   perceived  as  clickable.   task  analysis  focuses  on  the  properties  of  the  task  rather  than  the  user.  this  requires  expert   evaluation  in  place  of  involving  users  in  the  study.  as  stated  above,  both  of  the  authors  are   working  experts  in  the  field  of  user  experience  in  the  library  context,  thoroughly  aware  of  the   tasks  under  analysis  and  how  they  are  executed  on  a  daily  basis.  a  group  of  12  (librarians,   reference  service  staff,  system  administrators  and  developers)  were  asked  to  review  the  hta   charts  on  a  monthly  basis.  feedback  and  implications  of  identified  issues  were  discussed  as  a   group.  according  to  nielsen  [7]  it  takes  five  experts  (double  specialist  in  nielsen’s  terms,  is  an   expert  in  usability  as  well  as  in  the  particular  technology  employed  by  the  software.)  to  not  have   significant  loss  of  findings  (see  figure  7).  based  on  this  enumeration,  the  final  versions  of  the  hta   charts  offer  accurate  representations  of  the  primo  workflow  in  the  three  use  scenarios  of  finding   an  article,  finding  a  book  and  finding  an

 the  hta  will  be  discussed.  the  full  results  are   published  on  purdue  university  research  repository§.  table  1  presents  how  many  parallel  routes   (a  vs.  b  route),  physical  steps  (clicks),  cognitive  evaluation  steps,  likely  errors  and  well  guided   steps  each  of  the  use  cases  had.     on  average  it  took  between  20  to  30  steps  to  find  a  relevant  item  within  primo.  even  though  no   ideal  step  count  has  been  identified  for  the  library  context,  this  is  quite  high  in  the  general  context   of  the  web,  where  fast  task  accomplishment  is  generally  expected.  paul  chojecki  [33]  tested  how   too  many  options  impact  usability  on  a  website.  he  revealed  that  the  average  step  count  to  lead  to   higher  satisfaction  levels  is  6  (vs.  18,16  average  steps  at  purdue  libraries).  in  our  study,  the   majority  of  the  steps  were  physical  pressing  of  a  button  or  filter  selection;  however,  cognitive   steps  took  up  just  under  a  half  of  the  steps  in  nearly  all  cases.  the  majority  of  cases  flow  well,  as   the  strengths  (fluent  well  guided  steps)  of  primo  outweigh  its  less  guided  steps  that  easily  lend   themselves  to  the  chance  of  error.

 least  guided  and  required  the  highest  amount  of  decisions  from  the  user  (5,  vs.  4  for  books   and  4  for  ebooks  on  average).  retrieving  an  article  (between  23-­‐30  steps  on  average)  or  a  book   (24-­‐29  steps  on  average)  took  more  steps  to  accomplish  than  finding  a  relevant  ebook  (20-­‐26   steps  on  average).  the  high  volume  of  steps  (max  30  steps  on  average)  it  required  to  retrieve  an   article,  as  well  as  its  high  error  rate  (8),  were  due  to  the  higher  amount  of  cognitive  steps  (12   steps  on  average)  required  to  identify  the  correct  article  and  to  locate  a  hard  copy  (instead  of  the   relatively  easily  retrievable  online  copy).  in  the  book  scenario,  the  challenge  was  also  two-­‐fold:  on   the  one  hand,  it  was  challenging  to  verify  the  right  book  when  there  were  many  similar  results   (this  explains  the  high  number  of  12  cognitive  steps  on  average);  on  the  other  hand,  the  flow  to   place  a  request  for  a  book  was  also  a  challenge.  the  latter  was  a  key  contributor  to  the  higher   amount  of  physical  steps  required  for  retrieving  a  book  (max  29  on  average).         information  technology  and  libraries  |  march  2015   93   common  to  all  eleven  cases,  whether  articles  or  books,  was  the  four  sub-­‐goal-­‐process:  1)  browse   the  library  website,  2)  find  results,  3)  open  the  page  of  the  desired  item,  and  4)  retrieve,  locate   or  order  the  item.  the  first  two  offered  near  identical  experiences,  no  matter  the  search  scenario   or  case.  third  and  fourth  sub-­‐goals,  however,  presented  different  workflow  issues  depending  on   the  product  searched  and  its  availability,  e.g.  ‘in  print’  or  ‘online’.  as  such,  general  results  will  be   presented  for  the  first  two  themes,  while  scenario  specific  overviews  will  be  provided  for  the   latter  two  themes.   browsing  the  library  website   browsing  the  library  website  was  easy  and  supported  different  user  tasks.  the  simple  url   (lib.purdue.edu)  was  memorable  and  appeared  first  in  the  search  results.  the  immediate   availability  of  sub-­‐menus,  such  as  databases  and  catalogs,  offered  speedy  searching  for  the   frequent  users.  the  choice  between:  a)  general  url,  or  b)  sub-­‐menu,  was  the  first  key  decision   point  users  of  primo  at  purdue  libraries  were  presented  with.     the  purdue  libraries’  home  page  (revisit  figure  1)  had  a  simple  design  with  a  clear,  central  and   visible  search  box.  just  above  it  were  search  filters  for  articles,  books  and  the  web.  this  was  the   second  key  decision  point  users  were  presented  with:  a)  they  could  either  type  into  the  search  bar   without  selecting  any  filters,  or  b)  they  could  select  a  filter  to  aid  the  focus  of  their  results  to  a   specific  item  type.  browsing  the  library  website  offers  an  efficient  and  fluent  workflow,  with   ebooks  being  the  only  exception.  it  was  hard  to  know  whether  they  were  grouped  under  articles   or  books  &  media  filters.  confusingly  (at  the  time  of  the  study)  purdue  libraries  listed  ebooks  that   had  no  physical  copies  under  articles,  while  other  ebooks  that  purdue  had  physical  version  of  (in   addition  to  the  digital  ones)  under  books  &  media.  this  was  not  explained  in  the  interface,  nor  was   there  a  readily  available  tooltip.   finding  relevant  results     figure  9.  search  results  for  article  (case2)  ‘comparison  of  simple  potential  functions  for   simulating  liquid  water’     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang       94   primo  presented  the  search  results  in  an  algorithmic  order  of  relevance  offering  additional  pages   for  every  20  items  appearing  in  the  search  results.  the  search  bar  was  then  minimized  at  the  top   of  the  page,  available  for  easy  editing.  the  page  was  divided  into  two  key  sections,  where  the  first   quarter  entailed  filters  (e.g.  year  of  publishing,  resource  type,  author,  journal,  etc.),  and  the  other   three  quarters  was  left  for  search  results  (see  figure  8).  the  majority  of  cognitive  decisions  across   scenarios  were  made  on  this  results  page.  this  was  due  to  the  need  to  pick  up  the  cues  to  identify   and  verify  the  accurate  item  being  searched.  the  value  of  these  cognitive  steps  lies  in  their  leading   of  the  user  to  the  next  physical  steps.  as  discussed  in  the  next  section,  opening  the  page  of  the   desired  item,  there  were  several  elements  that  succeeded  and  failed  at  guiding  the  user  to  their   accurate  search  result.     search  results  were  considered  relevant  when  the  search  presented  results  in  the  general  topic   area  of  the  searched  item.  most  cases  in  most  scenarios  led  to  relevant  results,  however,  book   case  8  and  ebook  case  11,  provided  only  unrelated  results.  generally,  books  and  ebooks  were   easy  to  identify  as  available.  this  was  due  to  their  typically  short  titles,  which  took  less  effort  to   read.  journal  articles,  on  the  other  hand,  have  longer  titles  and  required  more  cognitive  effort  to   be  verified.     article  case  4,  book  case  6  and  ebook  case  10  had  relevant  but  restricted  results.  the  color-­‐ coding  system  that  indicated  the  level  of  availability  for  the  presented  search  results:  green  (fully   available),  orange  (partly  available)  or  gray  (not  available)  dots  –  was  followed  by  an  explanatory   availability  tag,  e.g.  'available  online'  or  'full  text  available'  etc.  tabs  represented  additional  cues,   offering  additional  information,  e.g.  ‘find  in  print’.  these  appeared  in  a  supplementary  way  where   applicable.  for  example,  if  an  item  was  not  available,  its  dot  was  gray  and  it  neither  had  the  'find   in  print'  nor  'find  online'  tab.  instead,  it  had  a  'request'  tab,  guiding  the  user  towards  an  available   alternative  action.  restricted  availability  items,  such  as  a  book  in  a  closed  repository,  had  an   orange  indicator  for  partial  availability.  for  these,  primo  still  offered  the  'find  in  print'  or  'find   online'  tab,  whichever  was  appropriate.  while  the  overall  presentation  of  item  availability  was   clear  and  color-­‐coding  consistent,  the  mechanisms  were  not  without  their  errors,  as  discussed   below.   opening  the  page  of  the  desired  item   this  sub-­‐goal  comprised  of  two  main  steps:  1)  information  driven  cognitive  steps,  which  help  the   user  identify  the  correct  item,  and  2)  user  interface  guided  physical  steps  that  resulted  in  opening   the  page  of  the  desired  item.     frequent  strengths  that  helped  the  identification  of  relevant  items  across  the  scenarios  were  the   clearly  identifiable  labels  underneath  the  image  icons  (e.g.  'book’,  'article',  ‘conference  proceeding'),   hierarchically  structured  information  about  the  items  (title,  key  details,  availability)  and   perceivably  clickable  links  (blue  with  an  underlined  hover  effect).  the  labels  and  hierarchically   presented  details  (e.g.  year,  journal,  issue,  volume,  etc.)  helped  the  workflow  to  remain  smooth,     information  technology  and  libraries  |  march  2015   95   minimizing  the  need  to  use  side  filters.  the  immediate  details  reduced  the  need  to  open   additional  pages,  cutting  down  the  steps  needed  to  accomplish  the  task.  the  hover  effect  of  item   titles  made  the  link  look  and  feel  clickable,  guiding  the  user  closer  to  retrieving  the  item.  color-­‐ coding  all  clickable  links  in  the  same  blue  was  also  an  effective  design  feature,  even  though  bolded   availability  labels  were  equally  prominent  and  clickable.  this  was  especially  true  for  articles   where  the  ‘full  text  available’  tags  correspond  to  users  goal  to  immediately  download  the  sought   item  (figure  8).   the  most  frequent  causes  of  errors  were  duplicated  search  results.  generally,  primo  displays   multiple  versions  of  the  same  item  into  one  search  result  and  offered  a  link:  ‘see  all  results’.  in  line   with  graham  stone’s  [17]  study,  which  highlighted  the  problem  of  cataloging  inconsistences,   primo  struggled  to  consistently  grouping  all  overlapping  search  result  items.  both  book  and   article  scenarios  suffered  from  at  least  one  duplicate  search  result  case  due  to  inconsistent  details.   article  scenario  case  2  offers  an  example,  where  jorgensen  et  al  “comparison  of  simple  potential   functions  for  simulating  liquid  water”  (1983)  had  two  separate  results  for  the  same  journal   article  of  the  same  year  (first  two  results  in  figure  8).  problematically,  the  two  results  offered   different  details  for  the  journal  issue  and  page  numbers.  this  may  cause  likely  referencing   problems  for  primo  users.   duplicated  search  results  were  also  an  issue  for  book  scenarios.  the  most  frequent  causes  for  this   were  instances  where  authors’  first  and  last  names  were  presented  in  a  reverse  order  (see  also   figure  8  for  article  case  2),  the  books  had  different  print  editions,  or  the  editors’  name  was  used   in  place  of  the  authors’.  book  scenario  case  7:  machiavelli’s  “the  prince”  resulted  in  extremely   varied  results,  requiring  16  cognitive  steps  and  33  physical  steps  before  a  desired  item  could  be   verified.  this  is  where  search  filters  were  most  handy.  problematically,  in  case  7,  machiavelli  –   the  author  –  did  not  even  appear  in  the  author  filter  list,  while  ebrary  inc  was  listed.  again,  this   points  to  the  inconsistent  metadata  and  the  effects  it  can  have  on  usability,  as  discussed  by  stone.2   other  workflow  issues  were  presented  by  design  details  such  as  the  additional  information  boxes   underneath  the  item  information,  e.g.  ‘find  in  print’,  ‘details’  and  ‘find  online’.  they  opened  a  small   scrollable  box  that  maintained  the  overall  page  view,  were  difficult  to  scroll.  the  arrow  kept   slipping  outside  of  the  box,  scrolling  the  entire  site’s  page  instead  of  the  content  inside  the  box.  in   addition,  the  information  boxes  did  not  work  well  with  chrome.  this  was  especially  problematic   on  the  macbook  where  after  a  couple  of  searches  the  boxes  failed  to  list  the  details  and  left  the   user  with  an  unaccomplished  task.  comparably,  safari  on  a  mac  and  internet  explorer  on  a  pc   never  had  such  issues.       retrieving  the  items  (call  number  or  downloading  the  pdf)   the  last  sub-­‐goal  was  to  retrieve  the  item  of  interest.  this  often  comprised  of  multiple  decision   points:  whether  to  retrieve  the  pdf  version  from  online  or  identify  a  call  number  for  the  physical     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang       96   copy  or  whether  to  place  a  request,  ordering  it  via  inter  library  loan  (ill)  or  uborrow.  each   option  is  briefly  discussed  below.     ebooks  and  articles,  if  available  online,  offered  efficient  online  availability.  if  an  article  was   identified  for  retrieval,  there  were  two  options  to  access  the  link  to  the  database,  e.g.  ‘view  this   record  in  acm’:  a)  via  the  full  view  of  the  item,  or  b)  small  ‘find  online’  preview  box  discussed   above.  where  more  than  one  database  was  available,  information  about  the  publication  range  the   library  holds  helped  identify  the  right  link  to  download  the  pdf  on  the  link-­‐resolver  page.  one  of   the  key  benefits  of  having  links  from  within  primo  to  the  full  texts  was  the  fact  that  they  opened  in   new  browser  windows  or  tabs,  without  interference  to  other  ongoing  search.  while  a  few  of  the   pdf  links  to  downloadable  texts  were  difficult  to  find  through  some  external  database  sites,  once   found,  they  all  opened  in  adobe  reader  with  easy  options  to  either  'save'  or  ‘print’  the  material.     ebooks  were  available  via  ebrary  or  ebl  libraries.  while  the  latter  offers  some  novel  uses,  such  as   audio  (i.e.  read  aloud),  neither  of  the  two  platforms  was  easy  to  use.  while  reading  online  was   possible,  downloading  an  ebook  was  challenging.  the  platform  seemed  to  offer  good  options:  a)   download  by  chapter,  b)  download  by  page  numbers,  or  c)  download  the  full  book  for  14  days.  in   actuality,  however,  these  were  all  unavailable.  ebook  case  9  had  chapters  longer  than  the  60-­‐page   limit  per  day.  page  numbers  proved  difficult  to  use,  as  the  book’s  numbers  did  not  match  the  pdf’s   page  numbers.  this  made  it  hard  to  keep  track  of  what  was  downloaded  and  where  one  left  off  to   continue  later  (due  to  imposed  time-­‐limits).  the  14-­‐day  full  access  option  was  only  available  in   adobe  digital  editions  software  (an  ebook  reader  software  by  adobe  systems  built  with  adobe   flash),  which  was  neither  available  on  most  campus  computers  nor  on  personal  laptops.     the  least  demanding  and  most  fluent  of  all  retrieval  options  was  the  process  of  identifying  the   location  and  call  number  for  physical  copies.  inconsistent  metadata,  however,  posed  some   challenges.    book  case  5  offered  a  merged  search  result  of  two  books,  but  listed  them  with   different  call  numbers  in  the  ‘find  in  print’  tab.  libraries  have  many  physical  copies  of  the  same   book,  but  identifying  consistency  in  call  number  is  a  cognitive  step  that  helps  verify  the   similarities  or  differences  between  the  two  results.  the  different  call  numbers  raised  doubts  about   which  item  to  choose,  slowing  the  workflow  for  the  task  and  increasing  the  number  of  cognitive   steps  required  to  accomplish  the  task.     compared  to  books,  finding  an  article  in  print  format  was  hardly  straightforward.  the  main  cause   for  error  when  looking  up  hard  copies  of  journals  was  the  fact  that  individual  journal  issues  did   not  have  individual  call  numbers  at  purdue  libraries.  instead,  they  were  had  one  call  number  per   periodical  where  the  entire  journal  series  had  only  one  call  number.  article  case  2,  for  example,   offered  the  journal  code:  530.5  j821  in  the  ‘find  in  print’  tab.  in  general,  the  tab  suffered  from  too   much  information,  poor  layout  and  unhelpful  information  hierarchy,  all  of  which  slowed  down  the   cognitive  tasks  of  verifying  whether  an  item  was  relevant  or  not.  it  listed  ‘location’  and  ‘holdings   range’  as  the  first  pieces  of  information,  wherein  ‘holdings  range’  included  not  just  hard  copy   related  information,  but  listed  digital  items  as  well,  even  though  this  tab  was  for  physical  version     information  technology  and  libraries  |  march  2015   97   of  the  item.  to  illustrate,  article  case  2  claimed  to  have  holdings  for  1900  –  2013,  whereas  hard   copies  were  only  available  for  1900-­‐2000,  and  digital  copies  for  2001-­‐2013.     each  scenario  had  one  or  two  cases  where  there  were  neither  physical  nor  digital  options   available.  the  sub-­‐goal  commonly  comprised  of  a  decision  between  three  options:  c)  placing  a   request,  d)  ordering  an  item  via  inter  library  loan  (ill),  or  c)  ordering  an  item  via  uborrow.   while  the  ‘signing  in  to  request’  option  and  ill  were  easy  to  use  with  few  required  steps,  there   was  a  lack  of  guidance  on  how  to  choose  between  the  three  options.  frequently,  ill  and  uborrow   appeared  as  equal  options  adjacent  to  one  another,  leaving  the  next  step  unguided.  of  all  three,   placing  a  request  via  uborrow  was  the  hardest  to  accomplish.  it  often  failed  to  present  any   relevant  results  on  the  first  results  page  of  the  uborrow  system,  requiring  the  use  of  advanced   search  and  filters.  for  instance,  book  case  6  was  ‘not  requestable’  via  uborrow.  when  it  did  list   the  sought  for  item  in  the  search  results  it  looped  back  to  purdue's  own  closed  repository  (which   remained  unavailable).     discussion   the  goal  of  this  study  was  to  utilize  hta  to  examine  the  workflow  of  the  primo  discovery  layer  at   purdue  university  libraries.  nielsen’s  [6]  goal  composition  heuristics  were  used  to  extend  the   task-­‐based  analysis  and  understand  the  tasks  in  the  context  of  discovery  layers  in  libraries.  three   key  usability  domains:  generalization,  integration  and  user  control  mechanisms  were  used  as  an   analytical  framework  to  draw  usability  conclusions  about  how  primo  was  supporting,  if  at  all,   successful  completion  of  the  three  scenarios.  the  next  three  sub-­‐sections  evaluate  and  offer  design   solutions  on  the  three  usability  domains  mentioned  above.  overall,  this  study  confirmed  primo’s   ability  to  reduce  the  workload  for  users  to  find  their  materials.  primo  is  flexible  and  intuitive,   permitting  efficient  search  and  successful  retrieval  of  library  materials,  while  offering  the   possibility  of  many  search  sessions  at  once  [14].    a  comparison  to  a  usability  test  results  is  offered   as  a  way  of  conclusion.     generalization  mechanisms   primo  can  be  considered  a  flexible  discovery  layer  as  it  helps  users  achieve  many  goals  with   minimum  amount  of  steps.  it  makes  use  of  several  generalization  mechanisms  that  allow  users  to   utilize  their  tasks  towards  many  goals  at  once.  for  instance,  the  library  website  result  in  google   offers  not  only  the  main  url  but  also  seven  sub-­‐links  to  specialist  library  site  locations,  such  as   opening  hours  and  databases.  this  makes  primo  accessible  and  relevant  for  a  broader  array  of   people  who  are  likely  to  have  different  goals.  for  instance,  some  may  seek  to  enter  a  specific   database,  instead  of  having  to  open  primo’s  landing  page  and  entering  the  search  terms.  another   may  wish  to  utilize  ‘find’,  which  guides  the  user,  one  step  at  a  time,  via  a  process  of  definition   elimination,  closer  to  the  item  they  are  looking  forknow  the  opening  times.   similarly,  the  primo  search  function  saves  already  typed  information,  both  on  its  landing  page  and   its  results  page.  this  facilitates  search  by  requiring  query  entry  only  once,  while  allowing  end     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang       98   users  to  click  on  different  filters  to  narrow  the  results  in  different  ways.  as  a  part  of  the  work  done   towards  one  search  can  be  used  towards  another,  e.g.  by  content,  journal,  or  topic  type,  the  system   can  ease  the  work  effort  required  of  users.  this  is  further  supported  by  the  system  saving  already   typed  keywords  when  returning  to  the  main  search  page  from  research  results  and  allows  for  a   fluid  search  experience  where  the  user  adjusts  a  keyword  thread  with  minimal  typing,  until  they   find  what  they  are  looking  for.   a  key  problem  for  primo  is  its  inability  to  manage  inconsistent  meta-­‐data.  the  tendency  to  group   different  versions  of  the  same  search  results  together  is  helpful  as  it  clarifies  information  noise.  in   an  effort  to  enhance  the  speed  it  takes  to  evaluate  the  relevancy  of  search  results,  the  system  seeks   to  shighlight  any  differences  in  the  meta-­‐data.  if  inconsistencies  in  meta-­‐data  cause  same  search   results  to  appear  as  separate  items,  it  is  likely  to  affect  the  cognitive  steps  and  therefore  the   workload  and  efficiency  with  which  the  user  is  able  to  accomplish  identification.     it  is  clear  from  previous  studies  that  if  discovery  layers  were  to  become  the  next  generation   catalogs  [11],  and  were  to  enhance  the  speed  of  knowledge  distribution  as  has  been  hoped  by   tosaka  and  weng  [15]  and  luther  and  kelly  [16],  then  mutual  agreement  is  needed  on  how  meta-­‐ data  from  disparate  sources  [17].  understanding  that  users’  cognitive  workload  should  be   minimized  (by  offering  fewer  options  and  more  directive  guidance)  for  more  efficient  decision-­‐ making,  library  items  should  have  accurate  details  in  their  meta-­‐data,  e.g.  consistent  and  thorough   volume,  issue  and  page  numbers  for  journal  articles,  correct  print  and  reprint  years  for  books,  and   item  type  (conference  proceeding  vs.  journal  article).   integration  mechanisms   the  discovery  layer’s  ability  to  increase  the  number  of  search  sessions  [14]  at  any  one  time  is   possible  due  to  its  flexibility  to  support  multitasking.  primo  achieves  this  with  its  own  individual   features  used  in  combination  with  other  system  facilities  and  external  sources.  for  instance,   primo’s  design  allows  users  to  review  and  compare  several  search  results  at  once  via  the  ‘find  in   print’  or  ‘details’  tabs.  although  not  perfect,  since  the  small  boxes  are  hard  to  scroll  within,  the   information  can  save  the  user  the  need  and  additional  steps  of  opening  many  new  windows  and   having  to  click  between  them  just  for  reviewing  search  results.  instead,  many  ‘detail’  boxes  of   similar  results  may  be  opened  and  viewed  at  once,  allowing  for  effective  visual  comparison.  this   integration  mechanism  allows  a  fluent  transition  from  skimming  the  search  results  to  another   temporary  action  of  gaining  insight  about  the  relevance  of  an  item.  most  importantly,  this  is   accomplished  without  requiring  the  user  to  open  a  new  browser  page  or  tab,  where  they  would   have  to  break  from  their  overall  search  flow  and  remember  the  details  (instead  of  visually   comparing  them),  making  it  hard  to  resume  from  where  they  left  off.     a  contrary  integration  mechanic  that  primo  makes  use  of  is  its  smooth  automated  connectivity  to   external  sites,  such  as  databases,  ebrary,  ill,  etc.  new  browser  pages  are  used  to  allow  the   continuation  of  a  task  outside  of  primo  itself  without  forcing  the  user  out  of  the  system  to  the     information  technology  and  libraries  |  march  2015   99   library  service  or  full  text.  primo  users  can  skim  search  results,  identify  relevant  resources  and   open  them  in  new  browser  pages  for  later  reviewing.     what  is  missing,  however,  is  the  opportunity  to  easily  save  and  resume  a  search.  retrieving  the   search  result  or  saving  it  under  ones’  login  details  would  benefit  users  who  recall  items  of  interest   from  previous  searches  and  would  like  to  repeat  the  results  without  having  to  remember  the   keywords  or  search  process  they  used.  it  is  not  obvious  how  to  locate  the  save  search  session   option  in  primo’s  interface.   user  control  mechanisms   yang  and  wagner  [11]  ranked  primo  highest  among  the  vendors,  primarily  for  its  good  user   control  mechanisms,  which  allow  users  to  inspect  and  change  the  search  functions  on  an  ongoing   basis.  primo  does  a  good  job  at  presenting  search  results  in  a  quick  and  organized  manner.  it   allows  for  the  needed  ‘undo’  functionality  and  continued  attachment  and  removal  of  filters,  while   saving  the  last  keywords  when  clicking  the  back  button  from  search  results.  the  continuously   available  small  search  box  also  offers  the  flexibility  for  the  user  to  change  search  parameters   easily.  in  summary,  primo  offers  agile  searching,  while  accounting  for  a  few  different  discovery   mental  models.     however,  if  primo  wants  to  preserve  its  current  effectiveness  and  make  the  jump  towards  a  single   search  function  that  is  truly  flexible  and  allows  for  much  needed  customizability  [18][2],  it  needs   to  allow  for  several  similar  user  goals  to  be  easily  executable  without  confusion  about  the  likely   outcome.  the  most  prominent  current  system  error  for  primo,  as  it  has  been  applied  in  the  purdue   libraries,  is  its  inability  to  differentiate  ebooks  from  journal  articles  or  books.  it  would  support   users  goals  to  be  able  to  start  and  finish  an  ebook  related  tasks  at  the  home  page’s  search  box.   currently,  users  have  the  cognitive  burden  to  consider  whether  ebooks  are  more  likely  to  be   found  under  ‘books  &  media’  or  ‘journals’.  currently,  primo,  as  applied  to  its  implementation  at   purdue  libraries  at  the  time  of  this  study,  does  not  support  goals  to  search  for  content  type,  e.g.  an   ebook.  this  however,  is  increasingly  popular  among  the  student  population  who  want  ebooks  on   their  tablets  and  phones  instead  of  carrying  heavy  books  in  their  backpacks.     another  key  pain-­‐point  for  current  users  is  the  identification  of  specific  journals  in  physical  form,   say  for  archival  research.  currently,  each  journal  issue  is  listed  individually  in  the  ‘find  in  print’   section,  even  though  the  journals  only  have  one  call  number.  listing  all  volumes  and  issues  of  each   periodical  overwhelms  the  user  with  too  much  information  and  prevents  the  effective   accomplishment  of  the  task  of  locating  a  specific  journal  issue.  since  there  is  only  one  call  number   available  for  the  entire  journal  sequence,  it  may  lead  to  better  clarity  and  usability  if  the   information  was  reduced.  instead  of  listing  all  possible  journal  issues,  a  range  or  ranges  (if   incomplete  set  of  issues)  that  the  library  has  physically  present  should  be  listed.  in  article  case  2,   for  instance,  there  are  five  items  for  the  year  1983.  why  lead  the  user  to  look  at  a  range  where   there  is  no  possible  option?     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang       100   comparing  hta  to  a  usability  test   usability  tests  benefit  from  the  invaluable  direct  input  from  the  end  user.  at  the  same  time   usability  studies,  as  constructed  conditions,  offer  limited  opportunities  to  learn  about  users’  real   motivations  and  goals  and  how  the  discovery  layers  support  or  fail  to  support  their  tasks.  fagan   et  al  [3]  conducted  a  usability  test  with  eight  students  and  two  faculty  members  to  learn  about   usability  issues  and  user  satisfaction  with  discovery  layers.  they  measured  time,  accuracy  and   completion  rate  for  nine  specific  tasks,  and  obtained  insights  from  task  observations  and  post-­‐test   surveys.  they  reported  on  issues  with  users  not  following  directions  (93),  the  prevalence  of  time   outs,  users  skipping  tasks,  and  variable  task  times.    these  results  all  point  to  a  mismatch  between   the  user  goals  and  the  study  tasks  and  offer  an  incomplete  picture  about  the  system’s  ability  to   support  user  goals  that  are  accomplished  via  specific  tasks.   expert  evaluation  based  hta  method  does  not  require  users’  direct  input.  hta  offers  a  method  to   achieve  a  relatively  complete  evaluation  of  how  low-­‐level  interface  facets  support  users’  high-­‐ level  cognitive  tasks.  hta  measures  the  system  designs  quality  in  supporting  a  specific  task   needed  to  accomplish  a  user  goal.  instead  of  measuring  time,  physical  and  cognitive  tasks  are   measured  in  number  of  steps.  instead  of  accuracy  and  completion  rate,  fluent  workflow  steps  and   mistaken  steps  are  counted.  the  two  methods  offer  opposite  strengths,  making  them  a  good   complements.  given  hta’s  system-­‐centric  approach,  it  can  better  inform  which  tasks  would  be   useful  in  usability  testing.   to  compare  the  our  research  findings  with  usability  tests,  fagan  et  al  [3]  confirmed  some  of  the   previously  established  findings  that  journal  titles  are  difficult  to  locate  via  the  library  home  page   (vs.  databases),  that  filters  are  handy  when  they  are  needed  and  that  users’  mental  models  have  a   preference  for  a  google-­‐like  single  search-­‐box.  for  instance,  students  and  even  librarians,  struggle   to  understand  what  is  being  searched  in  each  system  and  how  results  are  ranked  (see  also  [5]).   the  hta  method  applied  in  this  study  was  also  able  to  confirm  that  journal  titles  are  more   difficult  to  identify  than  books  and  ebooks,  the  flexibility  benefit  offered  by  filters  and  identify  the   single  search  box  as  a  fluent  system  design.  since,  hta  does  not  rely  on  the  user  to  tell  why  these   results  are  true,  hta,  as  applied  in  this  study,  helped  expert  evaluators  understand  the  reasons   for  these  findings  via  self-­‐directed  execution  and  discussion  with  colleagues  later.  depending  on   the  task  design,  either  usability  testing  or  hta  offer  the  capabilities  to  identify  cases  such  as   confusion  about  how  to  start  an  ebook  search  in  primo.  taking  a  system  design  approach  to  task   design  offers  a  path  to  a  systematic  understanding  of  discovery  layer  usability,  which  lends  itself   to  easier  comparison  and  external  validity.     in  terms  of  specific  interface  features,  usability  tests  are  good  for  evaluating  the  visibility  of   specific  features.  for  example,  fagan  et  al  [3]  asked  their  participants  to  (1)  search  on  speech   pathology,  (2)  find  a  way  to  limit  search  results  to  audiology,  and  then  (3)  limit  their  search   results  to  peer-­‐reviewed  (task  3  in  [3],  p.  95).  by  measuring  completion  rate,  they  were  able  to   identify  the  relative  failure  of  ‘peer-­‐reviewed’  over  ‘audiology’  filters,  but  they  were  left  “unclear     information  technology  and  libraries  |  march  2015   101   [about]  why  the  remaining  participants  did  not  attempt  to  alter  the  search  results  to  ‘peer  reviewed,”   failing  to  accomplish  the  task  [3].  in  comparison,  hta  as  an  analytical  rather  than  observational   methodology,  leads  to  more  synthesized  results.  in  addition  to  insights  into  possible  gaps   between  system  design  and  mental  models,  hta  as  a  goal-­‐oriented  approach,  concerns  itself  with   issues  of  workflow  (how  well  the  system  guides  the  user  to  accomplishing  their  task)  and   efficiency  (minimizing  the  number  of  steps  required  to  finish  a  task).  these  are  less  obvious  to   identify  with  usability  tests,  where  participants  are  not  impacted  by  their  routine  goals,  time   pressures  and  consequently  their  patience  may  be  more  tolerant  as  a  result.   the  application  of  hta  helped  identify  key  workflow  issues  and  map  them  to  specific  design   elements.  for  instance,  the  lack  of  ebooks  as  a  search  filter  meant  that  the  current  system  did  not   support  content  form  based  searching  well  for  two  mains  forms:  articles  and  books.  compared  to   usability  tests  that  focus  on  specific  fabricated  search  processes,  hta  aims  to  map  all  possible   routes  the  system’s  design  offers  to  accomplish  a  goal,  allowing  for  their  parallel  existence  during   the  analysis.  this  system-­‐centered  approach  to  task  evaluation,  we  argue,  is  the  key  benefit  hta   can  offer  towards  a  more  systematic  evaluation  of  discovery  layers,  where  different  user  groups   would  have  varying  levels  of  assistance  needs.  hta  task-­‐analysis  allows  for  the  nuanced   understanding  that  results  can  differ  as  the  context  of  use  differs.  that  applies  even  to  the   contextual  difference  between  user  test  participants  and  routine  library  users.     conclusion   discovery  layers  are  advancing  the  search  experiences  libraries  can  offer.  with  increasing   efficiency,  increased  ease  of  use  and  more  relevant  results,  scholarly  search  has  become  a  far  less   frustrating  experience.  while  google  is  still  perceived  as  the  holy  grail  of  discovery  experiences,  in   reality  it  may  not  be  quite  what  scholarly  users  are  after  [5].  the  application  of  discovery  layers   has  focused  on  eliminating  the  limitations  that  plagued  the  traditional  federated  search  and   improving  the  search  index  coverage  and  performance.  usability  studies  have  been  effective  in   verifying  these  benefits  and  key  interface  issues.  moving  forward,  studies  on  discovery  layers   should  focus  more  on  the  significance  of  discovery  layers  on  user  experience.   this  study  presents  the  expert  evaluation  based  hta  methods  as  a  complementary  way  to   systematically  evaluate  popular  discovery  layers.  it  is  the  system  design  and  goal-­‐oriented   evaluation  approach  that  offers  the  prospects  of  a  more  thorough  body  of  research  on  discovery   layers  than  usability  alone.  using  hta  as  a  systematic  preliminary  study  guiding  formal  usability   testing  offers  one  way  to  achieve  more  comparable  study  results  on  applications  of  discovery   layers.  it  is  through  comparisons  that  the  discussion  of  discovery  and  user  experience  can  gain  a   more  focused  research  attention.  as  such,  hta  can  help  vendors  to  achieve  the  full  potential  of   web-­‐scale  discovery  services.     to  better  understand  and  ultimately  design  to  their  full  potential,  systematic  studies  are  needed   on  discovery  layers.  this  study  is  the  first  attempt  to  apply  hta  towards  systematically  analyzing   user  workflow  and  interaction  issues  on  discovery  layers.  the  authors  hope  to  see  more  work  in     applying  hierarchical  task  analysis  method  to  discovery  layer  evaluation  |  promann  and   zhang

editor’s comments bob gerrity information technology and libraries | september 2012 1 g’day, mates, and welcome to our third open-access issue. ital takes on an additional international dimension with this issue, as your faithful editor has taken up residence down under, in sunny queensland, australia. the recent ala annual meeting in anaheim marked some changes to the ital editorial board that i’d like to highlight. cynthia porter and judith carter are ending their tenure with ital after many years of service. cynthia is featured in this month’s editorial board thoughts column, offering her perspective on library technology past and present. judith carter ends a long run with ital as managing editor, and i thank her for her years of dedicated service. ed tallent, director of levin library at curry college, is the incoming managing editor. we also welcome two new members of the editorial board: brad eden, the dean of library services and professor of library science at valparaiso university, and jerome yavarkovsky, former university librarian at boston college, and the 2004 recipient of ala’s hugh c. atkinson award. jerome currently co-chairs the library technology working group at the mediagrid immersive education initiative. we cover a broad range of topics in this issue. ian chan, pearl ly, and yvonne meulemans describe the implementation of the open-source instant messaging (im) network openfire at california state university san marcos, in supporting of the integration of chat reference and internal library communications. richard gartner explores the use of the metadata encoding and transmission standard (mets) as an alternative to the fedora content model (fcm) for an “intermediary” digital-library schema. emily morton and karen hanson present an innovative approach to creating a management dashboard of key library statistics. kate pittsley and sara memmott describe navigational improvements made to libguides at eastern michigan university. bojana surla reports on the development of a platform-independent, java-based marc editor. yongming wang and trevor dawes delve into the need for next-generation integrated library systems and early initiatives in that space. melanie schlosser and brian stamper begin to explore the effects of reposting library digital collections on flickr. in addition to the compelling new content in this issue of ital, we have compelling old content from the print archive of ital and its predecessor, journal of library automation (jola), that will soon be available online, thanks in large to the work of andy boze and colleagues at the university of notre dame. scans of all of the back issues have now been deposited onto the server that currently hosts ital, and will be processed and published online over the coming months. bob gerrity (r.gerrity@uq.edu.au) is university librarian, university of queensland, st. lucia, queensland, australia. letter from the editors (december 2023) letter from the editors kenneth j. varnum and marisha c. kelly information technology and libraries | decmber 2023 https://doi.org/10.5860/ital.v42i4.17014 the journal’s editorial board has begun work this fall in two main areas, building on last year’s work on our diversity statement: an updated scope statement and exploration of content areas to match. if you have thoughts about how ital can better support your professional work and career development, please let us know. additionally, we are working with guest editors peter musser and joy dubose on an artificial intelligence-themed special issue that will be published in 2024. we are excited about the articles in the pipeline for this issue and look forward to sharing more details about this issue and its contents next year. in this issue in addition to those articles, we are pleased to present contributions from other voices: • there are three items in the letters to the editor section. • in our occasional editorial board thoughts series, editorial board member mary guillory contributes “drained-pool politics versus digital libraries in u.s. cyberspace,” a discussion of book banning in digital environments. • our regular public libraries leading the way column is by ross hanney, “reorienting collection analysis: cost effective item level analysis and machine learning in public libraries.” this essay highlights an analysis of how a small-town public library can save its community’s residents money. peer-reviewed articles in the current issue are listed here: • “to thine own 3d selfie be true: outreach for an academic library makerspace with a 3d selfie booth,” by alex watson • “towards an open source-first praxis in libraries,” by j. robertson mcilwain • “managing your library’s libguides: conducting a usability study to determine student preference for libguide design,” by julie burchfield and maggie possinger • “using qualtrics xm to create a point-of-use survey to assess the usability of a local implementation of primo,” by matthew black, heather ganshorn, and justine wheeler • “reference chatbots in canadian academic libraries,” by julia guy, paul r. pival, carla j. lewis, and kim groome help keep ital going if you are interested in contributing to information technology and libraries, there are several ways for you to do so. the main one, of course, is through contributing an article. our call for submissions outlines the topics of interest to the journal—basically, if the submission discusses the intersection of libraries/archives/museums and technology, it’s potentially in scope—and the process for submitting an article. for those of you who are interested in contributing in other ways, two opportunities will be available in the first part of 2024. a call for peer reviewers for ital and our sibling core journals (library leadership & management and library resources & technical services) will be distributed in january. for those interested in serving on ital’s editorial board, our annual call for volunteers will be distributed to core members in april. kenneth j. varnum, editor marisha c. kelly, assistant editor varnum@umich.edu marisha.librarian@gmail.com

this in late september, as the boston red sox attempt to back their way into the major league baseball postseason after blowing a 9-game lead over tampa bay in a major-league september meltdown of epic proportions. [red sox fans are prone to hyperbole, but in this case no hyperbole is needed: this meltdown really is epic.] it’s down to the last game of the season, and like many red sox fans, i’m hopeful but not optimistic. the fate of the 2011 red sox will be old news by the time this appears in print, though: as i’m coming to learn, the wheels of scholarly publishing continue to turn ever so slowly, unless forced to do otherwise. which brings me to why i’m taking on the role of editor of ital. on one hand, i’m fortunate to be taking on the editorship of a journal that quite clearly has been stewarded with care, dedication, and attention by my predecessors. i’ve spent quite a few hours recently in the z678.9 section of my library’s stacks, perusing three decades of back volumes of ital and its predecessor, the journal of library automation. there’s an impressive body of scholarly and informational output on library automation and related topics, from the sublime (“to boolean or not to boolean?” september 1983), to the not-so-sublime (“the effects of baud rate, performance anxiety, and experience in online bibliographic searches,” march 1990), to the sentimental (“floppies to pass the billion-dollar level in ’84.” september 1982), to the déjà-vu-all-over-again (“ls2000—the integrated library system for oclc,” june 1984). overall, i’d have to say there’s a solid foundation to build on, plus plenty of good content in the pipeline, and it would be easy to continue on in the same vein. but that’s not why i’m here. i’m fortunate to be taking on the role of editor as ital faces significant changes. in his inaugural editorial for ital in march 2005, then-incoming editor john webb articulated a number of worthy goals for ital, to both broaden and deepen the content of the journal and the demographic of the authors contributing to it. one goal in particular, though, strikes me (in hindsight of course) as problematic: “i hope to . . . facilitate the electronic publication of articles without endangering—but in fact enhancing—the absolutely essential financial contribution that the journal provides to the association.” anyone who has observed the struggles of the newspaper industry in recent years or been involved in the shift towards e-only in the world of academic/scholarly journals will not be surprised to learn that, in the intervening years since john wrote his column and ital has continued in print plus electronic form, revenues (primarily from subscriptions and advertising) have steadily declined while production and distribution costs have not, resulting in an increasing annual subsidy from ala/lita to support the publication. as a result, i’ve been tasked with exploring a new publication model for ital: open access and electronic only. plans for—and the timing of — this transition are still being developed as i write this, but should be finalized before “my” first issue is published in march 2012. there is much about ital that will not change even if the publication format does. a primary focus of the journal will continue to be to solicit and publish high-quality, peer-reviewed papers covering a broad array of topics related to the design, application, and use of technology in libraries. changes i would like to see include making ital more timely and more relevant to the day-to-day work interests of many of its readers. i’d like to add more topical, current, and informational content to ital without negatively impacting its traditional role as a publication vehicle for librarians in tenure-track positions. ital in an e-only format also needs to provide easy and transparent ways for readers to be informed when new content is published and to offer advice, criticism, and commentary to help improve ital. i look forward to your feedback as ital moves in a new direction, about which i’m both hopeful and optimistic. i would like to offer my sincere thanks to the outgoing editor of ital, marc truitt, who has been both helpful and gracious during this editorial transition. marc is passionate about ital and its legacy, and i hope he’ll see the future ital as a worthy successor to, rather than an unfortunate break from, the journal he’s stewarded for the past several years. incoming editor’s column: ch-ch-ch-ch-changes (turn and face the strain) bob gerrity (robert.gerrity@bc.edu) is associate university librarian for information technology, boston college libraries, chestnut hill, massachusetts. 6 information technology and libraries | march 2011 i n the new lita strategic plan, members have suggested an objective for open access (oa) in scholarly communications. some people describe oa as articles the author has to pay someone to publish. that can be true, but that’s not how i think of it. oa is definitely not vanity publishing. most oa journals are peer-reviewed. i like the definition provided by enablingopenscholarship: open access is the immediate (upon or before publication), online, free availability of research outputs without any of the restrictions on use commonly imposed by publisher copyright agreements.1 my focus on oa journals increased precipitously when the licensing for a popular american weekly medical journal changed. we could only access online articles from one on-campus computer unless we increased our annual subscription payment by 500 percent. we didn’t have the funds, and now the students suffer the consequences. i think it was an unfortunate decision the journal’s publishers made. i know from experience that if a student can’t access the first article they want, they will find another one that is available. interlibrary loan is simpler than ever, but i think only the patient and curious students will make the effort to contact us and request an article they cannot obtain. in 2006 scientist gary ward wrote that faculty at many institutions experience problems accessing current research. when faculty teach “what is available to them rather than what their students most need to know, the education of these students and the future of science in the u.s. will suffer.” he explains it is a false assumption that those who need access to scientific literature already have it. interlibrary loans or pay-per-view are often offered by publishers as the solution to the access problem, but this misses an essential fact of how we use the scientific literature: we browse. it is often impossible to tell from looking at an abstract whether a paper contains needed methodological detail or the perfect illustration to make a point to one’s students. apart from considerations of cost, time, and quality, interlibrary loans and pay-per-views simply do not meet the needs of those of us who often do not know what we’re looking for until we find it.2 i want our medical students and tomorrow’s doctors to have access to all of the most current medical research. we offer the service of providing jama articles to students, but i’m guessing that we hear from a small percentage of the students who can’t access the full text online. are people reading oa articles? not only are scholars reading the articles, but they are citing those articles in their publications. consider the public library of science’s plosone (http://www.plosone.org/home.action), a peerreviewed, open-access, online publication that features reports on primary research from all disciplines within science and medicine. in june 2010, plosone received its first impact factor of 4.351—an impressive number. that impact factor puts plosone in the top 25 percent of the institute for scientific information’s (isi) biology category.3 the impact factor is calculated annually by isi and represents the average number of citations received per paper published in that journal during the two preceding years.4 in other words, articles from plosone published in 2008 and 2009 were highly cited. is oa making an impact in my medical library? i believe it is, although i won’t be happy until our students can access the online journals they want from off campus and the library won’t have to pay outrageous licensing fees. we have more than one thousand online oa journal titles in our list of online journals. the more full text they can access, the less they’ll have to settle for their second or third choice because their first choice is not available online. i’m glad that lita members included oa in their strategic plan. the number of oa journals is increasing, and i believe we will continue to see that the articles are reaching readers and making a difference. i don’t think ital will be adopting the “author pays” model of oa, but the editorial board is dedicated to providing lita members with the access they want. references 1.

policy, and stan­ dards development are all arenas in which ala and lita both take an active role. lita has articulated in its strategic plan the need to pursue active involvement in providing its expertise on national issues and standards development. lita achieves these important objectives in a variety of ways. lita has several committees, interest groups, and representatives to ala standing committees that address legislation, regulation, and national policy issues that pertain to technology. the charge of the lita legislation and regulations committee reads: “the legislation and regulation committee monitors legislative and regula­ tory developments in the areas of information and communications technologies; identifies relevant issues affecting libraries and assists in developing appropri­ ate strategies for responding to these issues.” as its educational mission, the committee publicizes issues and strategies on the lita web site. the chairperson of this committee serves as the lita representative to the ala legislation assembly which advises ala on positions to take regarding legislative and regulatory action. lita also has a representative to the ala office of information technology policy advisory committee who works closely with the legislation and regulation committee on it policy issues that may cross over into the legislative realm. lita also appoints a representa­ tive to the ala intellectual freedom committee whose purpose is “to recommend such steps as may be neces­ sary to safeguard the rights of library users, libraries, and librarians, in accordance with the first amendment to the united states constitution and the library bill of rights.” much has happened on the national front in the past few years that provides plenty of work for these lita and ala committees. the patriot act, calea, net neutrality, dopa, ada compliance, and debates over copyright and intellectual property rights in an electronic world are all examples of issues that require technologi­ cal control or affect systems and network solutions. they also touch at the heart of what librarians have always stood for: protection of intellectual property, personal pri­ vacy, and intellectual freedom. library technologists exert enormous time and effort protecting the privacy of patron records through data retention policies, system controls, and strong authentication systems all while providing authorized access to intellectual property according to copyright or licensing restrictions. keeping lita mem­ bers apprised of all of these issues and the technologies required to abide by legal requirements is an enormous task of the committees and interest groups. these groups do this through programming, publications, and postings to the lita web site. lita has always been very active on the standards development front. from the start, lita was involved with the marc standards through the hard work of henriette avram. the number of standards that affect libraries has mushroomed. there are standards for all aspects of technology—data formats, hardware and firmware, and networking. ala regularly calls on lita to provide expertise on developing standards that per­ tain to library technology. lita has a standards interest group and shares membership with alcts and rusa on the marbi committee. most lita interest groups deal with standards of some sort at least occasionally. the lita board felt that lita’s work on develop­ ing standards was so important that in 2006 a new standards coordinator position was created and diane hillman, cornell university, was appointed as the first person in this role. the standards coordinator identifies lita experts to assist in calls for review of developing standards and seeks input from the membership. the standards coordinator works closely with the standards interest group to help educate the membership. because of the nature of digital information, networks, and the standards that enable the distribution of digital informa­ tion and services, it has become impossible for any one person to understand all the standards that affect the library technologist. as standards proliferate, it becomes more important for lita to provide educational oppor­ tunities alongside the involvement in the development of these standards that so impact our daily lives. the lita web site provides a wealth of information about standards. a new means of contributing to the dialogue about developing standards is to participate in the lita wiki where diane hillman will be leading the way in posting information about various library technology standards. also, a great place to learn about various stan­ dards is right here in ital. practically every issue has at least one article about one standard or another. lita’s participation in technological developments on the national front is critical to all libraries. policy, regu­ lation, and standards form the infrastructure to techno­ logical implementation and are the cornerstone to library technology. lita is the place where you can learn more about these developments and participate in the dialogue about them. bonnie postlethwaite (postlethwaiteb@umkc.edu) is lita president 2006/2007 and associate dean of libraries, university of missouri–kansas city. president’s column bonnie postlethwaite reference information extraction and processing using conditional random fields tudor groza, gunnar aastrand grimnes, and siegfried handschuh reference information extraction and processing |groza, grimnes, and handschuh 6 abstract fostering both the creation and the linking of data with the scope of supporting the growth of the linked data web requires us to improve the acquisition and extraction mechanisms of the underlying semantic metadata. this is particularly important for the scientific publishing domain, where currently most of the datasets are being created in an author-driven, manual manner. in addition, such datasets capture only fragments of the complete metadata, omitting usually, important elements such as the references, although they represent valuable information. in this paper we present an approach that aims at dealing with this aspect of extraction and processing of reference information. the experimental evaluation shows that, currently, our solution handles very well diverse types of reference format, thus making it usable for, or adaptable to, any area of scientific publishing. 1. introduction the progressive adoption of semantic web 1 techniques resulted in the creation of a series of datasets connected by the linked data 2 initiative, and via the linked data principles, into a universal web of linked data. in order to foster the continuous growth of this linked data web, we need to improve the acquisition and extraction mechanisms of the underlying semantic metadata. unfortunately, the scientific publishing domain, a domain with an enormous potential for generating large amounts of linked data, still promotes trivial mechanisms for producing semantic metadata. 3 as an illustration, the metadata acquisition process of the semantic web dog food server, 4 the main linked data publication repository available on the web, consists of two steps:  the authors manually fill-in submission forms corresponding to different publishing venues (e.g., conferences or workshops), with the resulting (usually xml) information being transformed via scripts into semantic metadata, and  the entity uris (i.e., authors and publications) present in this semantic metadata are then manually mapped to existing web uris for linking/consolidation purposes. tudor groza (tudor.groza@uq.edu.au) is postdoctoral research fellow,

mailto:tudor.groza@uq.edu.au mailto:grimnes@dfki.uni-kl.de mailto:msiegfried.handschuh@deri.org information technology and libraries | june 2012 7 moreover, independent of the creation/acquisition process, one particular component of the publication metadata, i.e., the reference information, is almost constantly neglected. the reason is mainly the amount of work required to manually create it, or the complexity of the task, in the case of automatic extraction. as a result, currently, there are no datasets in the linked data web exposing reference information, while the number of digital libraries providing search and link functionality over references is rather limited. this is quite a problematic gap if we consider the amount of information provided by references and their foundational support for other application techniques that bring value to researchers and librarians, such as citation analysis and citation metrics, tracking temporal author-topic evolution 5 or co-authorship graph analysis. 6,7 in this paper we focus on the first of the above-mentioned steps, i.e., providing the underlying mechanisms for automatic extraction of reference metadata. we devise a solution that enables extraction and chunking of references using conditional random fields (crf). 8 the resulting metadata can then be easily transformed into semantic metadata adhering to particular schemas via scripts, the added value being the exclusion of the manual author-driven creation step from the process. from the domain perspective, we focus on computer science and health sciences only because these domains have representative datasets that can be used for evaluation and hence enable comparison against similar approaches. however, we believe that our model can be applied also in domains such as digital humanities or social sciences, and we intend, in the near future, to build a corresponding corpus that would allow us to test and adapt (if necessary) our solution to these domains. figure 1. examples of chunked and labeled reference strings reference chunking represents the process of label sequencing a reference string, i.e., tagging the parts of the reference containing the authors, the title, the publication venue, etc. the main issue associated with this task is the lack of uniformity in the reference representation. figure 1 presents three examples of chunked and labeled reference strings. one cannot infer generic patterns for all types of references. for example, the year (or date) of some of the references of this paper are similar to example 2 from the figure, i.e., they are located at the very end of the reference string. unfortunately, this does not hold for some journal reference formats, such as the one presented in example 1. and at the same time, the actual date might not comprise only the year, but also the month (and even day). in addition to the placement of the particular types of tokens within the reference string, one of the major concerns when labeling these types of tokens is disambiguation. generally, there are three categories of ambiguous elements: reference information extraction and processing |groza, grimnes, and handschuh 8  names—can act as authors, editors, or even part of organization names (e.g., max planck institute); in example 1 a name is used as part of the title;  numbers—can act as pages, years, days, volume numbers, or just numbers within the title;  locations—can act as actual locations or part of organization names (e.g., univ. of wisconsin) to help the chunker in performing disambiguation, one can use a series of markers, such as, pp. for pages, tr for technical reports, univ. or institute for organization. however, there are cases where such markers help in detecting the general category of the token, e.g., publication venue, but a more detailed disambiguation is required. for example, the proc. marker generally signals the publication venue of the reference, without knowing exactly whether it represents a workshop, conference or even journal (as in the case of proc. natl. acad. sci.—proceedings of the national academy of sciences). the solution we have devised was built to properly handle such disambiguation issues and the intrinsic heterogeneous nature of references. the features of the crf chunker model were chosen to provide a representative discrimination between the different fields of the reference string. consequently, as the experimental results show, the resulting chunker has a superior efficiency, while at the same time maintaining an increased versatility. the rest of the paper is structured as follows: in section 2 we briefly describe conditional random fields and analyze the existing related work. section 3 details the crf-based reference chunker and before concluding in section 5, section 4 presents our experimental results. 2. background 2.1 conditional random fields to have a better understanding of the machine learning technique used by our solution, in the following we give a brief description of the conditional random fields paradigm. figure 2. example linear crf—showing dependencies between features x and classes y information technology and libraries | june 2012 9 conditional random fields (crf) is a probabilistic graphical model for classification. crf, in general, can represent many different types of graphical models, however in the scope of this paper, we use the so-called linear-chain crfs. a simple example of a linear dependency graph is shown in figure 2, here only the features x of the previous item influences the class of the current item y. the conditional probability is defined as: ( | ) ( ) (∑ ( ) ) where ( ) ∑ ( ) and ( ) ∑ (∑ ( ) ) . the model is usually trained by maximizing the log-likelihood of the training data by gradient methods. a dynamic algorithm is used to compute all the required probabilities p⍬(yi, yi+1) for calculating the gradient of the likelihood. this means that in contrast to traditional classification algorithms in machine learning (e.g., support vector machines 9 ), it not only considers the attributes of the current element when determining the class, but also attributes of preceding and succeeding items. this makes it ideal for tagging sequences, such as chunking of parts of speech or parts of references, which is what we require for our chunking task. 2.2 related work in recent years, extensive research has been performed in the area of automatic metadata extraction from scientific publications. most of the approaches focus on one of the two main metadata components, i.e., on the heading/bibliographic metadata or on the reference metadata, but there are also cases when the entire set is targeted. as this paper focuses only on the second component, within this section we present and discuss those applications that deal strictly with reference chunking. the parscit framework is the closest technique mapping to our goals and methodology. 10 parscit is an open-source reference-parsing package. while its first version used a maximum entropy model to perform reference chunking, 11 currently, inspired by the work of peng et al. , 12 it uses a trained crf model for label sequencing. the model was obtained based on a set of twenty-three token-oriented features tailored towards correcting the errors that peng's crf model produced. our crf chunker builds on the work of parscit. however, as we aimed at improving the chunking performance, we altered some of the existing features and introduced additional ones. moreover, we have compiled significantly larger gazetteers required for detecting different aspects, such as names, places, organizations, journals, or publishers. one of the first attempts to extract and index reference information led to the currently well known system, citeseer. 13 around the same period, seymore et al. developed one of the first reference chunking approaches that used machine learning techniques. 14 the authors trained a hidden markov model (hmm) to build a reference sequence labeler using internal states for different parts of the fields. as it represented pioneering work, it also resulted in the first gold standard set, the cora dataset. at a later stage, the same group applied crf for the first time to perform reference chunking, which later inspired parscit. 15 reference information extraction and processing |groza, grimnes, and handschuh 10 in the same learning-driven category is the work of han et al. 16 the authors proposed an effective word clustering approach with the goal of reducing feature dimensionality when compared to hmm, while at the same time improving the overall chunking performance. the resultant domain, rule-based word clustering method for cluster feature representation used clusters formed from various domain databases and word orthographic properties. consequently, they achieved an 8.5 percent improvement on the overall accuracy of reference fields classification combined with a significant dimensionality reduction. flux-cim 17 is the only unsupervised 18 approach that targets reference chunking. the system uses automatically constructed knowledge bases from an existing set of sample references for recognizing the component fields of a reference. the chunking process features two steps:  a probability estimation of a given term within a reference which is a value for a given reference field based on the information encoded in their knowledge bases, and  the use of generic structural properties of references. similarly to seymore et al., 19 the authors have also created two datasets (specifically for the computer science and health science areas) to be used for comparing the achieved accuracies. a completely different, and novel, direction was developed by poon and domingos. 20 unlike all the other approaches, they propose a solution where the segmentation (chunking) of the reference fields is performed together with the entity resolution in a single integrated inference process. they, thus, help in disambiguating the boundaries of less-clear chunked fields, using the already well-segmented ones. although the results achieved are similar to, and even better than some of, the above-mentioned approaches, this is suboptimal from the computational perspective: the chunking/resolution time reported by the authors measured around thirty minutes. in addition to the previously described works, which were specifically tailored for bibliographic metadata extraction, there are a series of other approaches that could be used for the same purpose. for example, cesario et al. propose an innovative recursive boosting strategy, with progressive classification, to reconcile textual elements to an existing attribute schema. 21 in the case of bibliographic metadata segmentation, the metadata fields would correspond to the textual elements, while an ontology describing them (e.g., dublincore 22 or swrc 23 ) would have the schema role. the authors even describe an evaluation of the method using the dblp citation dataset, however, without giving precise details on the fields considered for segmentation. some other approaches include, in general, any sequence labeling techniques, e.g., slf, 24 named entity recognition techniques, 25 or even field association (fa) terms extraction, 26 the latter working on bibliographic metadata fields in a quasi-similar manner as the recursive boosting strategy. in conclusion, it is worth mentioning that retrieving citation contexts is an interesting research area especially in the context of digital libraries. our current work does not feature this aspect, but we regard it as one of the key next steps to be tackled. consequently, we mention the research performed by schwartz et al. 27 teufel et al., 28 or wu et al. 29 that deal with using citation contexts for discerning a citation's function and analyzing how this influences or is influenced by the work it points to. information technology and libraries | june 2012 11 3. method this section presents the crf chunker model. we start by defining the preprocessing steps that deal with the extraction of the references block, dividing the block into actual reference entries and cleaning the reference strings, and then detail the crf reference chunker features. 3.1 prerequisites most of the features used by the crf chunker require some forms of vocabulary entries. therefore, we have manually compiled a comprehensive list of gazetteers (only for english, except for the names), explained as follows:  firstname—25,155 entries gazetteer of the most common first names (independent of gender);  lastname—48,378 entries list of the most common surnames;  month—month names gazetteer and associated abbreviations;  venuetype—a structured gazetteer with five categories: conference, workshop, journal, techreport, and website. each category has attached its own gazetteer, containing specific keywords and not actual titles. for example, the conference gazetteerfeatures ten unigrams signaling conferences, such as conference, conf, or symposium;  location—places, cities, and countries gazetteer comprising 17,336 entries;  organization—150 entries gazetteer listing organization prefixes and suffixes (e.g., e.v. or kgaa);  proceedings—simple list of all possible appearances of the proceedings marker;  publisher—564 entries gazetteer comprising publisher unigrams (produced from around 150 publisher names);  jtitle—12,101 entries list of journal title unigrams (produced from around 1600 journal titles);  connection—a 42 entries stop-word gazetteer (e.g., to, and, as). 3.2 preprocessing in the preprocessing stage we deal with three aspects:  cleaning the provided input,  extracting the reference block, and  the division of the reference block into reference entries. the first step aims to clean the raw textual input received by the chunker of unwanted spacing characters while at the same time ensuring proper spacing where necessary. since the source of the textual input is unknown to the chunker, we make no assumptions with regard to its structure or content. 30 thus, in order to avoid inherent errors that might appear as a result of extracting the raw text from the original document, we perform the following cleaning steps:  we compress the text by eliminating unnecessary carriage returns, such that the lines containing less than 15 characters are merged with previous ones, 31  we introduce spaces after some punctuation characters, such as “,,” “.” or “-”, and finally,  we split the camel-cased strings, such as johndoe. reference information extraction and processing |groza, grimnes, and handschuh 12 the result will be a compact and clean version of the input. also, if the raw input is already compact and clean, this preprocessing step will not affect it. the extraction of the reference block is done using regular expressions. generally, we search in the compacted and cleaned input for specific markers, like references or bibliography, located mainly at the beginning of a line. if these are not directly found, we try different variations, such as, looking for the markers at the end of a line, or looking for split markers onto two lines (e.g., ref – erences, or refer – ences). this latter case is a typical consequence of the above-described compacting step if the initial input was erroneously extracted. the text following the markers is considered for division, although it may contain unwanted parts such as appendices or tables. the division into individual reference entries is performed on a case basis. after splitting the reference block based on new lines, we look for prefix patterns at the beginning of each line. as an example, we analyze which lines start with “[”, “(”, or a number followed by “.” or space, and we record the positions of these lines in the list of all lines. to ensure that we don't consider any false positives when merging the adjacent lines into a reference entry, we compute a global average of the differences between positions. assuming that a reference does not span on more than four lines, if this average is between one and four, a reference entry is created. the same average is also used to extract the last reference in the list, thus detaching it from eventual appendices or tables. 3.3 the reference chunking model we have built the crf learning model based on a series of features used in principle also by the other crf reference chunking approaches such as parscit 32 or peng and mccallum 33 . a set of feature values is used to characterize each token present in the reference string, where the reference's token list is obtained by dividing the reference string into space-separated pieces. the complete list of features is detailed as follows. we use example 1 from figure 1 toexemplify the feature values.  token—the original reference token: bronzwaer,  clean token—the original token, stripped of any punctuation and lower cased: bronzwaer  token ending—a flag signaling the type of ending (possible values: lower cap – c / upper cap – c / digit – 0 / punctuation character: ,  token decomposition–start—five individual values corresponding to token's first five characters, taken gradually: b, br, bro, bron, bronz  token decomposition–end—five individual values corresponding to the token's last five characters, taken gradually: r, er, aer, waer, zwaer,  pos tag—the token's part of speech tag (possible values: proper noun phrase – nnp ,  noun phrase – np, adjective – jj, cardinal number – cd, etc): nnp  orthographic case—a flag signaling the token's orthographic case (possible values:  initialcap, singlecap, lowercase, mixedcaps, allcaps): singlecap  punctuation type—a flag signaling the presence and type of a trailing punctuation character (possible values: cont, stop, other): cont  number type—a flag signaling the presence and type of a number in the token (possible values: year, ordinal, 1dig, 2dig, 3dig, 4dig, 4dig+, nonumber): nonumber information technology and libraries | june 2012 13  dictionary entries—a set of ten flags signaling the presence of the token in the set of individual gazetteers listed in sect. 3.1. for our example the dictionary feature set would be: no lastname no no no no no no no no  date check—a flag checking whether the token may contain a date in form of a period of days, e.g., 12-14 (possible values: possdate, no): no  pages check—a flag checking whether the token may contain pages, e.g., 234–238 (possible values: posspages, no): no  token placement—the token placement in the reference string, based on its division into nine equal consecutive buckets. this feature indicates the bucket number: 0 for training purposes we compiled and manually tagged a set of 830 randomly chosen references. these were extracted from random publications from diverse conferences and journals from the computer science field (collected from ieee explorer, springer link or the acm portal), manually cleaned, tagged, and categorized according to their type of publication venue. 34 to achieve an increased versatility, instead of performing crossvalidation, 35 which would result in a datasettailored model with limited or no versatility, we opted for sampling the test data. hence, we included in the training corpus some samples from the testing datasets as follows: 10 percent of the cora dataset (i.e., 20 entries), 36 10 percent of the flux-cim cs dataset (i.e., 30 entries), 37 and 1% of the flux-cim hs dataset (i.e., 20 entries). consequently, the final training corpus consisted of a total of 900 reference strings. to clarify, this is, to some extent, similar to the dataset-specific cross-validation, but instead of considering, for example, a 60–40 ratio for training/testing, we used only 10 percent for training, while the testing (described in section 4) was performed as a direct application of the chunker on the entire dataset. as already mentioned, our focus on computer science and health sciences is strictly due to evaluation purposes. our proposed model is domain-agnostic, and hence, the steps described here can be easily performed on datasets emerged from other domains, if at all necessary. in reality, the chunker’s performance on references from a domain not covered above can be easily boosted simply by including a sample of references in the training set and then retraining the chunker. the list of labels used for training and then testing consists of author, title, journal, conference, workshop, website, technicalrep, date, publisher, location, volnum, pages, etal, note, editors, organization. as we will see in the evaluation, not all labels were actually used for testing (e.g., note or editors), some of them being present in the model for the sake of disambiguation. also, as opposed to the other approaches, we made a clear distinction between workshop and conference, which adds an extra degree to the complexity of the disambiguation. the crf model was trained using the mallet (a machine learning for language toolkit) implementation. 38 the output of the chunker is post-processed to expose a series of fine-grained details. as shown in figure 1 in all the examples, the chunking provides a blocked partition of the reference string, but we require for the author field an even deeper partition. consequently, following a rule-based approach we extract the individual author names from the author block making use of the punctuation marks, the orthographic case, and the alternation between initials and actual names. when no initials, subject to the existing punctuation marks, we consider as a rule-of-thumb that each name generally comprises one first name and one surname (in this order, i.e., john doe). the result of the post-processing is used in the linking process. reference information extraction and processing |groza, grimnes, and handschuh 14 4. experimental results we have performed an extensive evaluation of the proposed reference chunking approach. in general, all the previous work in reference chunking focuses on raw reference chunking, i.e., label sequencing at the macro level. more concretely, the other approaches split and tag the reference strings using blocks of complete references, without going into details such as chunking individual authors. the only exception is the parscit package that does perform complete reference chunking in a similar fashion as we do. the evaluation results presented in this section, will feature complete chunking only for our solution and for parscit, and raw chunking for the rest of the approaches. field parscit peng han et al. our approach p r f1 f1 p r f1 p r f1 author 98.7 99.3 98.99 99.4 92.6 99.1 97.6 99.08 99.6

b u t are not considered for evaluation  unlike all the other approaches, we make the distinction between conference and workshop as publication venues. however, for alignment purposes (i.e., to be able to compare our results with the other approaches), in the evaluation results these are merged into the booktitle field. the actual tests were performed on four different datasets, three of them used also for evaluating the other approaches, and a fourth one compiled by us. in the case of the three existing datasets, during the experimental evaluation we did not make use of the preprocessing step as they were already clean. as evaluation metric, we used the f1 score, 39 i.e., the harmonic mean of precision and recall, using the following formula: information technology and libraries | june 2012 15 in the following, we iterate over each dataset, by providing a short description and the experimental results. it is worth mentioning that our crf reference chunker was trained only once, as described earlier, and not specifically for each dataset. 4.1 dataset: cora the cora dataset is the first gold standard created for automatic reference chunking. 40 it comprises two hundred reference strings and focuses on the computer science area. each entry is segmented into thirteen different fields: author, editor, title, booktitle, journal, volume, publisher, date, pages, location, tech, institution and note. table 1 shows the comparative evaluation results on the cora dataset of parscit, peng et al., 41 han et al., 42 and our approach. we observe that our chunker outperforms the other chunkers on most of the fields, with some of them presenting a significant increase in performance (looking at the f1 score): journal from 91.3 percent to 95.68 percent, booktitle from 93.44 percent to 98.10 percent, publisher from 91.83 percent to 95.33 percent, and especially tech. rep. from 86.7 percent to 95.23 percent. in the case of the fields where our chunker was outperformed, the f1 score is very close to the best of the approaches and includes an increase in one of its two components (i.e., precision or recall). for example, on the organization field, we scored 93.54percent, the best being peng's 94 percent. however, we achieved a gain of almost 10 percent in precision when compared with parscit (100 percent vs. 90.9 percent precision). similarly, on the date field, our f1 was 98.99 percent, opposed to parscit's 99.19 percent, but with a better recall of 98.67 percent. field parscit flux-cim our approach p r f1 p r f1 p r f1 author 98.8 99.0 98.89 93.59 95.58 94.57

reference information extraction and processing |groza, grimnes, and handschuh 16 4.1 dataset: flux-cim flux-cim 43 is an unsupervised 44 reference extraction and chunking system. in order to evaluate its performance, the authors of flux-cim created two separate datasets:  the flux-cim cs dataset, composed on a collection of heterogeneous references from the computer science field, and  the flux-cim hs dataset is comprised of an organized and controlled collection of references from pubmed. the flux-cim cs dataset contains three hundred reference strings randomly selected from the acm digital library. each string is segmented into ten fields: author, title, conf, journal, volume, number, pub, date, pages and place. the flux-cim hs dataset contains 2000 entries, with each entry segmented into six fields: author, title, journal, volume, date and pages. table 2 presents the comparative test results achieved by parscit, flux-cim, and our approach on the cs dataset. similar to the cora dataset, our chunker outperformed the other chunkers on the majority of the fields, exceptions being the location, journal, and publisher fields. the test results on the hs dataset are presented in table 3. here we can observe a clear performance improvement on all fields, in some cases the difference being significant, e.g., the title field, from 85.01 percent to 97.39 percent, or the journal field, from 93.12 percent to 99.28 percent. this increase is even more relevant considering the size of the dataset, each 1percent representing twenty references. 4.3 dataset: cs-sw while the cora and flux-cim cs datasets do focus on the computer science field, they do not cover the slight differences in reference format that can be found nowadays in the semantic web community. consequently, to show the even broader application of our approach, we have compiled a dataset named cs-sw comprising 576 reference strings randomly selected from publications in the semantic web area, from conferences such as international semantic web conference (iswc), the european semantic web conference (eswc), the world wide web conference (www), or the european conference on knowledge acquisition (and co-located workshops). 45 each reference entry is segmented into twelve fields: author, title, conference, workshop, journal, techrep, organization, publisher, date, pages, website and location. table 4 shows the results of the tests carried out on this dataset. one can easily observe that the chunker performed in a similar manner as on the cora dataset, with emphasis on the author, date, pages and publisher fields. field our approach p r f1 author 98.61 99.27 98.93 title 94.91 93.29 94.09 date 98.89 98.34 98.61 pages 98.94 97.24 98.08 location 93.9 92.77 93.33

from scientific publications. the solution, realized using a crf trained chunker, achieved good results in the experimental evaluation, in addition to an increased versatility shown by applying the one-time trained chunker on multiple testing datasets. this enables a straightforward adoption and reuse of our solution for generating semantic metadata in any digital library or publication repository focused on scientific publishing. as next steps, we plan to create a comprehensive dataset covering multiple heterogeneous domains (e.g., social sciences or digital humanities) and evaluate the chunker’s performance on it. then we will focus on developing an accurate reference consolidation and linking technique, to address the second step mentioned in section 1, i.e., aligning the resulting metadata to the existing linked data on the web. we plan to develop a flexible consolidation mechanism by dynamically generating and executing sparql queries from chunked reference fields and filtering the results via two string approximation metrics (a combination of monge-elkan and chapman soundex algorithms). the sparql queries generation will be implemented in an extensible manner, via customizable query modules, to accommodate the heterogeneous nature of the diverse linked data sources. finally, we intend to develop an overlay interface for arbitrary online publication repositories, to enable on-the-fly creation, visualization, and linking of semantic metadata from repositories that currently do not expose their datasets in a semantic / linked manner.

library jack w. scott: kent state university library, kent, ohio (formerly lorain county community college, lorain, ohio) a functioning technical processing system in a two-year community college library utilizes a model 2201 friden flexowriter with punch card control and tab card reading units, an ibm 026 key punch, and an ibm 1440 computer, with two tape and two disc drives, to produce all acquisitions and catalog files based primarily on a single typing at the time of initiating an order. records generated by the initial order, with slight updating of information,. are used to produce, via computer, manual and mechanized order files and shelf lists, catalogs in both the traditional 3x5 card form and book form, mechanized claiming of unfilled orders, and subject bibliographies. the lorain county community college, a two-year institution designed for 4000 students, opened in september 1964, with no librarian and no library collection. when the librarian was hired in october 1964, lack of personnel, both professional and clerical, forced him to examine closely traditional ways of ordering and preparing materials, his main task being the controlled building of a collection as quickly as possible. no library having been established, there were no inflexible rules governing acquisitions or cataloging and no catalogs or other files enforcing their pattern on future plans. the librarian was free to experiment and adapt as much as he desired; and adapt and experiment he did, remembering, at least most of the time, the primary reasons for designing the 150 journal of library automation vol. 1/3 september, 1968 system. these were 1) to notify the vendor about what material was desired; 2) to have readily available information about when material had been ordered and when it might arrive; 3) to provide a record of encumbrances; 4) to make sure that material received was the material which had been ordered; 5) to initiate payment for material received; 6) to provide catalog copy for technical processes to use in producing card and book catalogs; 7) to provide inexpensive control cards for a circulation system; and 8) to provide whatever other statistics might be needed by the librarian. the librarian attended the purdue conference on library automation (october 2-3, 1964) and an ibm conference on a-utomation held in cleveland (december 1964), and visited libraries with data processing installations, such as the decatur public library. then an extensive literature search was run on the subject of mechanization of libraries and the available material thoroughly reviewed. it was the consensus of the president, the librarian, and the manager of data processing that, as white said later, "the computer will play a major part in how libraries are organized and operated because libraries are a part of the fabric of society and computers are becoming a daily accepted part of life." ( 1) moreover, it was agreed that the use of data processing equipment would be justified only if it made building a collection more efficient and more economical than manual methods could do. metro}) after careful consideration of the ibm 870 document writing system ( 2) and the system described by kraft ( 3) as input techniqu~s for the college library, ·it . was decided to use the friden flexowriter, recommended both at purdue and, in european applications, by bernstein ( 4). its most attractive feature was the use of paper tapes to generate various secondary. records without the necessity of proofreading each one. the college, by mid-1965, ·had the following equipment available for library use: one friden flexowriter (model 2201) with card punch control unit and tab card reading unit, one ibm 026 key punch with alternate programming, and guaranteed time on the college-owned ibm 1440 8k computer with two tape and lwo disc drives. to produce punched paper tape and tab cards with only one keyboarding, an electrical connection between the flexowtiter and the keypunch was especially designed and installed. . it was fortunate for the library that the college also had an excellent data processing· manager who was interested in seeing data processing machines and techniques utilized in as many ways as possible. with his enthusiastic support, aid in programming and preparation of flow charts, and patient cooperation, it was not surprising that the automation of library processes was completely successful. ·· at this time it ·was decided that since the college was likely to remain integrated computer based processing/ scott 151 a single-campus institution it would be uneconomical to rely solely on a book catalog, even though the portability of such a device was most attractive to librarian and faculty alike. therefore, it was planned to have the public catalog, as well as the official shelf list, in card form, permitting both to be kept current economically. these two files were to be supplemented with crude book catalogs which would be a by-product, among others, of the typing of the original book orders. these book catalogs were not to replace the card catalog but simply to extend and facilitate use of the collection. it was also decided to design a system which would duplicate as few as possible of the manual aspects of normal technical processing systems, but one which would, at the same time, permit the return to a manual system from a machine system with a minimum of trouble and tribulation if support for the library's automated system should be withdrawn. concern about such withdrawal of support had originally been voiced by durkin and white in 1961, when they said: "there have been a number of unfortunate examples of libraries that abandoned their home-grown catalogs for a machine retriev(tl program because there was some free computer time, only to lose their machine time to a higher priority project and to be left with information storage to which they no longer have access. many of these librarians, and others who have heard about their plight, are determined not to bum their bridges behind' them by abandoning their reliable, if old-fashioned, 3x5 card catalogs." ( 5) although the necessity of returning to an inefficient manual system has not, to date, raised its ugly head, there were times when it was most comforting to know that routes of retreat and reformation were available. under the present system there is only one manual keyboarding of descriptive catalog main entries for most titles. all other records are generated from these main entries. this integrated system was adopted on the assumption that cataloging infonnation in some form ( 6) would be available for a high percentage of books. experience showed that about 95 percent of acquisitions did have catalog copy readily available. of 4029 titles processed in a 5-month period, catalog copy was available for 3824. after verification that a requested title is neither in the library nor on order, a copy of a catalog entry is located in a source such as the national union catalog, library of congress proofsheets, or publisher's weekly, etc. the catalog information is manually typed in its entirety (including subject headings) onto five-part multiple request forms, using the friden flexowriter. output from the friden consists of the multiple order, a punched paper tape containing the full bibliographic entry but no order information, and tab cards, punched by the slave ibm key punch, which contain full order information but only abbreviated bibliographic data. (figure 1 ). the tab cards, containing full order information, are used as input to the 1440 computer to create an "on order" file arranged by order 152 /ou·rnal of library automation vol. 1/ 3 september, 1968 mail copies to vendor typed multiple book orders on order tape fig. 1 on order creation routine. start flexowriter 026 key punch on order cards cards to week integrated computer based p1'0cessing / scott 153 number and stored on magnetic tape, from which an "on order" printout is produced weekly (figure 2). at any given time this magnetic tape order file can be used to total the dollar amount of outstanding orders to any given vendor, or the total amount outstanding to all vendors (figure 3 ). the punched paper tape and two copies of the request form are stored in a standard 3x5 card file arranged by main entry. one copy of the request form is to be used as a work slip when material is received. on order cards for one week fig. 2 on order update. start cpu on order update scratc h a f ter update 154 journal of library automation vol. 1/ 3 september, 1968 the original and one copy of the request form is sent to the vendor, with instructions to return one copy with shipment. in the event the vendor does not comply, the main entry can be located readily by checking the order number or order .date on the "on order" printout and using the abbreviated bibliographic information which appears there. if the material requested has not been shipped within three months, the magnetic tape order file is used to prepare tab cards containing all original order information and the cards are sent to the library with a notice stating that shipment is overdue. these tab cards are used as input fig. 3 on order cost tally. start cpu list or tab of on order file by cost #30000 on order cost tab integrated computer based processing/ scott 155 to the flexowriter tab card reader unit which activates the flexowriter itself and prepares "overdue, ship or cancel" notices to the vendor (figfig. 4 late on order routine. ure 4). 156 journal of library automation vol. 1/ 3 september, 1968 products when material is received, the paper tape and one copy of the main entry work slip are pulled from the card order file and sent to the cataloger who notes on the work slip the call number to be used as well as any changes. the work slip, punched paper tape and book then pass to the technician who does the shelf listing. at this point the original output paper tape containing full bibliographic information is used as input for the flexowriter to create a standard 3x5 hard-copy shelf list card containing full bibliographic information, as well as inventory data such as vendor, date of receipt and cost. the last three items and the call number are added manually as "changes." simultaneously a new paper tape is produced as output which contains bibliographic information from the first tape and all revisions deemed necessary by the cataloger. the revised paper tape is used on the flexowriter to prepare 3x5 card sets for the public catalog. at the same time the slave keypunch prepares a set of tab cards containing full acquisitions fig. 5 shelf list creation routine. integrated computer based processing/scott 157 information: cost, vendor, date of receipt; and abbreviated bibliographic information: short author, short title, full call number (including copy, year, part and volume), accession number and short edition statement (figure 5). the tab cards are used first to delete the item from the magnetic tape "on order" file and second as input to create a magnetic tape shelf list of abbreviated information arranged by call number (figure 6). the magnetic tape shelf list is used to create 1) eight copies of author, title, and classified catalogs which are updated semi-annually; 2 ) printouts of weekly acquisitions; 3) subject printouts on demand; and 4) tab cards which serve as circulation cards for books, film s, drawings, tape and disc recordings, filmstrips and any other materials. the tab cards can be used with the ibm 357 circulation system or any similar system. discussion the efficiency of this system is most dramatically demonstrated by the amount of work accomplished per person per year. one technician can sort by call number cpu circ. caro prep fig. 6 weekly shelf list update. sort by control number cpu 158 journal of library automation vol. 1/ 3 september, 1968 process over one thousand orders per month. over fifteen thousand fully cataloged volumes per year (approximately eleven thousand titles) are added to the collection by a technical processing department which consists solely of one full-time cataloger and two full-time technicians. one technician spends one half of her time typing orders and the other half preparing the shelf list. at present the limiting factor in processing material is not the personnel time available but rather time on the flexowriterkeypunch combination, which runs continuously for sixty hours per week. the cataloger feels if some thirty hours more per week were available for running the machines, or if a second flexowriter were available to handle catalog card output, it would then be possible to order, receive, and fully process fifteen thousand titles per year (eighteen to twenty thousand volumes) with only the present technical processing staff. references 1. white, herbert s.: "to the barricades! the computers are coming!" special libmries 57 (november, 1966), 631. 2. general information manual: mechanized library procedures (white plains, n.y.: ibm, n.d.). 3. kraft, donald h .: libmry automation with data processing equipment (chicago: ibm, 1964). 4. bernstein, hans h.: "die verwendung von flexowritern in dokumentation und bibliothek", n achrichten fur dokumentation 12 (june, 1961), 92. 5. durkin, robert e.;

one was a baby at only four months old. when one considers the rate of change in information technologies today, one understands the need for blogs, wikis, lists, and other forms of profes­ sional discourse in our field. what role does ital play in this rapidly changing environment? for one, unlike these newer forms, it is double­blind refereed. published articles run a peer review gauntlet. this is an important distinction, not least to the many lita members who work for aca­ demic institutions. it may be crass to state it so baldly, but publication in ital can help one earn tenure, an old­fashioned fact of life. it is indexed or abstracted in nineteen published sources, not all of them in english. many of its articles appear in various digital repositories and archives, and these also are harvested or indexed or both. in addition, its articles are cataloged in worldcat local. many of lita’s most prominent members—your distinguished peers—have published articles in ital. the journal also serves as a source for the wider dis­ semination of sponsored research, a requirement of most grants. and you can read it on the bus or at the beach (heaven forbid!), in the brightest sunlight, or with a flashlight under the covers (though there are no reports of this ever having been observed). i am amazed at how quickly these three years have passed, though that may be at least as much a function of my advanced age as of the fun and pleasure i have had as editor. certainly, these past three years have hosted some notable landmarks in our history. lita and ital both celebrated their fortieth anniversaries. sadly, the death of one of lita’s founders and ital’s first editor, frederick g. kilgour, on july 31, 2006, at age ninety­two, was a landmark in the passing of an era. oclc and rlg’s merger, which fred lived to witness, was a landmark of a different sort—one of maturity, we hope. ital is now an electronic as well as a print journal. this conversion has had some rough passages, but i trust these will have been ironed out by the time you read this. when i became editor, i had a number of goals for the journal, which i stated in my first editorial in march 2005. reading that editorial today, i realize that we successfully accomplished the concrete ones that were most important to me then: increasing the number of articles from library and i­school faculty; increasing the number that result from sponsored research; increasing the number that describe any relevant research or cutting­edge advance­ ments; increasing the number of articles with multiple authors; and finding a model for electronic publication of the journal. the accomplishment of the most abstract and ambitious goal, “to make ital a destination journal of excellence for both readers and authors,” only you, the readers and authors, can judge. i thank mary taylor, lita executive director, and her staff for all of the support they provided to me during my term. i owe a debt that i can never repay to all of the staff of ala production services who worked with me these past three years. their patience with my some­ times bumbling ways was award­winning. thank all of you. the lita presidents and other officers and board members were unfailingly supportive, and i thank you all. in the lita organizational structure, the ital editor and the editorial board report to the lita publications committee, and the editor is a member of that body. i thank all of the chairs and other members of that commit­ tee for their support. once more, and sadly for the last time, i thank all of the members of the ital editorial board who served dur­ ing my term for their service and guidance. they perform more than their share of refereeing, but more importantly, as i have written before, they are the junkyard dogs who have kept me under control and prevented my acting on my worst instincts. i say again, you, the lita member­ ship and ital readership, owe them more than you can ever guess. trust me. to marc truitt, ital managing editor and the incom­ ing ital editor for the 2008–2010 volume years, i must say, “thank you, thank you, thank you!” marc and the ala production services staff were responsible for the form, fit, and finish of the journal issues you received in the mail, held in your hands, and read under the covers. finally, most of all, thank you authors whose articles, communications, and tutorials i have had the privilege to publish, and you whose articles have been accepted and await publication. john webb (jwebb@wsu.edu) is a librarian emeritus, washington state university, and editor of information technology and libraries. editorial: farewell and thank you | john webb 3 not only is this the end of my term as editor, but i also have retired. from now on, my only role in the field of library and information technology will be as a user. those of you have seen the movie the graduate probably remember the early scene when benjamin, the dustin hoffman character, receives the single word of advice regarding his future: “plastics.” (i don’t know if that scene is in the novel from which the movie was adapted.) my single word of advice to those of you too young or too ambitious to retire from our field is: “handhelds.” i am surprised that my treo is more valuable to me now in retirement than it was when i was working. (i’m not surprised that my ipod video is, nor that word thinks that treo and ipod are misspellings.) i just wish that more of the web was as easily accessible on my treo as are google maps and almost all of yahoo!. handhelds. trust me. president’s message andromeda yelton information technology and libraries | march 2018 2 andromeda yelton (andromeda.yelton@gmail.com) is lita president 2017-18 and senior software engineer, mit libraries, cambridge, massachusetts. in my last president’s message, i talked about change — ital’s transition to new leadership — and imagination — wakanda and the archival imaginary. today change and imagination are on my mind again as lita contemplates a new path forward: potential becoming a new combined division with alcts and llama. as you may have already seen on litablog (http://litablog.org/2018/02/lita-alcts-and-llamadocument-on-small-division-collaboration/), the three divisional leadership teams have been envisioning this possibility, and all three division boards discussed it at midwinter. while the id ea sprang out of our shared challenges with financial stability, in discussing it we’ve realized how much opportunity we have to be stronger together. for instance, we’ve heard for years that you, lita members, want more of a leadership training pathway, and more ways to stay involved with your lita home as you move into management; alignment with llama automatically opens up all kinds of possibilities. they have an agile divisional structure with their communities of practice and an outstanding set of lead ership competencies. and anyone involved with library technology knows that we live and die by metadata, but we aren’t all experts in it; joining forces with alcts creates a natural home for people no matter where they are (or where they’re going) on the technology/metadata continuum. alcts also runs far more online education than lita and runs a virtual conference. meanwhile, of course, lita has a lot to offer to llama and alcts. you already know how rewarding the networking is, and how great the depth of expertise on technology topics. we also bring strong publications (like this very journal), marquee conference programs (like top tech trends and the imagineering panel), and a face-to-face conference. (speaking of which, please pitch a session (http://bit.ly/2gpgxdf) for the 2018 lita forum!) i want to emphasize that no decisions have been made yet. the outcome of our three board discussions was that we all feel there is enough merit to this proposal to explore it further, but none of us are formally committed to this direction. furthermore, it is not practically or procedurally possible to make a change of this magnitude until at least 2019. in the meantime, we expect there will be numerous working groups to determine if and how this all could work, as well as open forums for the membership of all three divisions to express hopes, concerns, and ideas. personally, my highest priority is to ensure that that you, the members, continue to have a divisional home: one that gives you learning opportunities and a place for professional camaraderie, and that is on solid financial footing so it can continue to be here for you in the long term.

that furthers the library’s mission of providing access to all forms of information and supporting pedagogy and scholarship across disciplines. academic libraries are increasingly adopting vr technology for a variety of research and teaching purposes, which include providing enhanced access to digital collections, offering new research tools, and constructing new immersive learning environments for students. this trend suggests that positive technological innovation is flourishing in libraries, but there remains a lack of clear guidance in the library community on how to introduce these technologies in effective ways and make them sustainable within different types of institutions. in june 2018, the university of oklahoma hosted the second of three forums on the use of 3d and vr for visualization and analysis in academic libraries, as part of the project developing library strategy for 3d and virtual reality collection development and reuse (lib3dvr), funded by a grant from the institute of museum and library services. this qualitative study invited experts from a range of disciplines and sectors to identify common challenges in the visualization and analysis of 3d data, and the management of vr programs, for the purpose of developing a national library strategy. introduction virtual reality, 3d data, and other spatial technologies are being adopted in libraries as innovative and immersive tools for enhancing research and teaching.1 vr provides a highly realistic, interactive visualization platform for engaging with 3d data, such as models produced from cultural heritage sites or medical imaging data, presenting many potential applications for a range of academic fields.2 while these technologies are not new, they have become increasingly affordable, enabling widespread adoption beyond their traditional niches. for example, vr equipment has been studied in computer science departments for decades, but costs restricted use to large research labs.3 consumer-oriented vr headsets emerged in the late 1980s, but at a high mailto:matt_cook@harvard.edu mailto:zlkatz@ou.edu mailto:nfhall@vt.edu mailto:jlhardes@iu.edu

https://doi.org/10.6017/ital.v38i4.11075 price point and with many technical challenges, such as high latency in interactive graphics processing, they were ultimately unsuccessful in the consumer marketplace. cheaper and technically superior mass-market vr headsets became widely available in 2016 with the release of the oculus rift and htc vive systems. vr is finally within the budgetary and technical means of libraries of various sizes to adopt and deploy. at the same time, educators are developing new methods of crafting vr content. decreasing costs of equipment associated with 3d data creation techniques, such as photogrammetry, laser scanning, and medical imaging (e.g., ct scanning), have encouraged their adoption outside of specialized fields. this content is increasingly used within immersive learning environments. spatial data creation and visualization tools together can comprise a 3d/vr ecosystem that enables a range of research activities, including 3d scanning of cultural heritage artifacts, drone scanning of landscapes, interactive mapping, and data visualization, all of which can be viewed and analyzed in immersive vr.4 there is already evidence to suggest that vr has many academic benefits. while vr has not yet been proven to lead to better learning outcomes when compared with other educational media (indeed for learning certain types of facts, videos and lectures are often still mo re effective), it does offer other types of benefits. vr has been shown to lead to changes in student attitudes, such as increasing student engagement or self-efficacy.5 furthermore, research has shown the positive impact that 3d and vr visualization can have on analytic tasks for researchers, which indicates the benefit of having this type of equipment and support available through academic libraries. 6 despite decreasing costs and a growing understanding of the potential benefits of the technology, there is still concern in the library field about the cost and sustainability issues associated with bringing these types of technologies into the library. there are currently no standards or best practices in place for adopting 3d/vr, so institutions often have to develop ad hoc solutions, which wastes time by duplicating work already being done in other institutions and makes it difficult to share content due to a lack of interoperability standards. to begin to address these challenges and aid in the maturation of 3d and vr as learning and research technologies, an interdisciplinary group of librarians from virginia tech, indiana university, and the university of oklahoma convened to develop a series of three national forums on this topic, funded by the institute for museum and library services (imls), as a project titled developing library strategy for 3d and virtual reality collection development and reuse (lib3dvr).7 each forum was designed to cover a particular phase of the 3d/vr lifecycle within academic contexts. in june 2018, the second forum was held at the university of oklahoma on the topic of 3d/vr visualization and analysis and considered the following research questions: rq1: what are effective strategies for addressing common challenges faced by academic libraries as they implement 3d and vr programs? rq2: how are academic librarians using vr to support existing library services, such as curriculum development and access? rq3: how can the knowledge and resources of academic library–based 3d/vr programs be shared with other academic and information organizations, such as public libraries and regional higher-education institutions? information technology and libraries | december 2019 27 this paper presents the findings of the 3d/vr visualization and analysis forum, discusses the common challenges and strategies identified, and indicates key directions forward. the forum assembled invited experts representing academic libraries, commercial software companies, vr and visualization labs, and educational research centers for two days of closed-door discussions. the forum identified common challenges faced by a diverse range of stakeholders and institutions of various types and scales, synthesized strategies and practices discussed by forum participants as possible solutions to those challenges, and presented policies that participants are developing to support vr as a research and learning tool in their institutions. in addition to convening experts in the field, a public forum was also held that brought together diverse stakeholders from the south central united states library community to provide opportunities for engagement and knowledge sharing. participants in the public forum represented local academic libraries, public libraries, public k-12 educators, commercial vr developers, and other academic programs. this enabled the cross-pollination of ideas and sharing of best practices for implementing vr in a range of contexts not represented by the invited experts. including such a diverse group enabled the wider academic and library communities to benefit from the sharing of information that is otherwise often siloed or restricted to large institutions with substantial economic and knowledge resources. literature review a growing body of literature on vr has considered the technology’s general benefits, explored its potential applications for research, presented methods of integrating vr into the classroom, defined some of the institutional challenges of adopting vr, and considered the use of vr for expanding library services. the general benefits of vr while the science that informs the development of contemporary vr systems has its roots in nineteenth-century scientific perceptual research (and even further back we can see rene descartes’ seventeenth-century theory of vision establishing the groundwork for contemporary vr systems development) it has been primarily within the last two decades that computer science and electrical engineering departments have defined the platform characteristics that reveal vr to be uniquely beneficial for working with complex 3d data.8 under controlled conditions, researchers have identified and tested the prevalence and impact of myriad “real-world” depth cues; benefits related to preservation of the embodied first-person viewer in a virtual environment; and the importance of increased viewing angles for engaging with what would traditionally be considered cluttered data sets.9 combined, this set of features allows for more efficient analysis of visual information, especially as related to activities where the user is expected to search, identify, describe, and compare subcomponents of complex, multivariate data sets.10 research has thus shown that vr is valuable because it presents information in context, at human scale, and in a way that is responsive to a wide range of body-centered interactions and representational characteristics that reproduce real-world interactions. these general benefits can be applied across academic disciplines and institutions. uses of vr in research the general benefits of vr that have been identified are now regularly employed in research capacities across the academy. vr and related 3d data-creation tools are being applied to fields such as digital humanities,11 archaeology,12 cultural heritage preservation,13 medieval studies,14 challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 28 https://doi.org/10.6017/ital.v38i4.11075 engineering,15 biology and biodiversity research,16 medicine,17 and architecture.18 in some cases, these approaches draw on the capabilities of 3d/vr to recreate immersive, high-fidelity experiences of real-world spaces, while in other cases, researchers are exploring the capabilities of vr to provide a platform for analyzing spatially oriented research data in the form of 3d models of cultural heritage artifacts and sites or visualizations of multivariate quantitative data. 19 in all of these cases, vr extends the capabilities of the human senses to engage with digital research data and scholarly outputs in ways that open new possibilities for discovery and analysis. integrating vr into the classroom starting with work on second life, quest atlantis, and others, researchers have also studied the pedagogical potential of virtual worlds.20 these early virtual worlds consisted of computergenerated 3d environments, but user engagement was limited to viewing them on 2d computer monitors and interacting via keyboard and mouse interfaces. early virtual classrooms were designed and studied in the hope that they could effectively bring students and teachers together from across the world and enable them to engage with distant artifacts, locations, and people as part of the curriculum, and early research was concerned with how virtual worlds could emulate or expand on the benefits of traditional learning environments.21 for example, jeremy bailenson has argued that vr is particularly well-suited for providing field trips to students, i.e., learning experiences that enable students to visit new places, and chris dede has identified the benefits and challenges of vr field trips.22 one of the main challenges of this type of learning technology is the high cost of designing and building the virtual environments; however, as bailenson points out, once they are created they can be endlessly replicated and shared, “enabling us to share educational opportunities with anyone who has an internet connection and an hmd [headmounted display].”23 with the increasing adoption by schools and libraries of vr equipment due to decreasing equipment costs, the focus has shifted to studying the pedagogical benefits of immersive vr experiences. these experiences place the user in an interactive, stereoscopic world, with interface controls modeled on intuitive embodied gestures and movements. vr has been shown to aid design and learning tasks in a range of fields, including design work in architecture classes24 and anatomical instruction in medical schools.25 these vr experiences augment, but do not replace, other forms of classroom learning, just as traditional field trips provide interactive learning experiences that contribute to formal classroom learning. while these applications are impressive, the high cost of vr adoption leads to concern about evaluating the benefits of vr for learning. what types of benefits are valued and how do we evaluate those benefits in rigorous ways? bailenson points out that vr may not facilitate factual knowledge acquisition better than other educational delivery methods; instead, it may have other benefits, such as increased student engagement, enthusiasm, and self -efficacy.26 indeed, lischerkatz et al. showed how a carefully designed course integration using vr could have a positive impact on undergraduate students’ self-efficacy in regards to spatial analytic tasks and technology engagement.27 mina johnson-glenberg studied two unique attributes of vr, “the sense of presence, and embodied affordances of gesture and manipulation in the 3rd dimension,” and generated findings that supported the hypothesis that “when learners perform actions with agency and can manipulate content during learning, they are able to learn even very abstract content better than those who information technology and libraries | december 2019 29 learn in a more passive and low embodied manner.”28 schneider et al., kuliga et al., and pober and cook have all documented the impact of vr on the process of architectural design.29 in the case of schneider et al., students engaged with digital and physical versions of the same facilities via virtual and real-world tours over the course of a semester. while students were critical of the digital surrogates’ relative lack of atmospheric detail, they also communicated that “experiencing the 3d-model in real size helped to evaluate the design.”30 similarly, angulo successfully integrated vr into her undergraduate architecture coursework, resulting in a documented increase in term-project evaluation scores for those students who iterated on designs using a vr viewing tool.31 these studies reflect the potential impact of vr across the design disciplines (e.g. , architecture), where such tools are already being deployed in professional settings.32 collectively, these studies indicate the likely benefits of vr in the classroom across disciplines, especially in fields where accurate perceptions of spatial characteristics—such as depth and scale—are critical to student (and professional) success. additional work is necessary to develop and streamline pedagogical research instrumentation whereby easily applied metrics can be implemented by library and instructional staff to evaluate the effectiveness of vr on students and other users. institutional experiences of adopting vr with the release of consumer-grade vr equipment, more and more institutions are considering the feasibility of adopting vr. as a result, case studies, practical strategies, and models for institutional deployment of vr are beginning to appear in the published literature.33 for example, austin olney discusses the implementation of augmented reality (ar) systems at the white plains public library in new york, and suggests that this endeavor is more easily accomplished by building off of existing vr capabilities and policies. in particular, logistical and legal concerns that had been addressed when previously deploying “public” vr (e.g., the signing of waivers before use) were useful for rapid deployment of ar.34 bohyun kim offers practical considerations for the integration of vr systems into library makerspaces, assessing suitable vr hardware and software to support 3d-modeling activities at the university of rhode island libraries.35 patterson and coworkers define five service models for integrating vr into libraries (see table 1 below). service model intended use open lab space walk-in closed lab space demonstrations, testing, and staging of new equipment flexible lab space reservable space and equipment for class or team use equipment checkout individual use developer kits (laptops and vr equipment) for checkout to use in research, demonstrations, and presentations table 1. library service models for vr.36 one of the major challenges faced by all institutions adopting vr is the concern over user comfort while using vr systems. as steven lavalle suggests, “experiencing discomfort as a side effect of using vr systems has been the largest threat to widespread adoption of the technology over the challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 30 https://doi.org/10.6017/ital.v38i4.11075 past decades.”37 fortunately, published best practices concerning baseline performance standards for consumer headsets and software design considerations have been well established in the literature, suggesting that those looking to adopt vr in institutional settings can do so by drawing on existing technical knowledge concerning how to ensure the relative comfort of vr users.38 this combination of practical and technical considerations will undoubtedly further the adoptio n of vr across educational institutions worldwide. the remainder of this article reports on the methodology and findings of this forum, which expand upon the benefits and challenges identified in the literature. methods the conveners assembled a two-and-a-half-day forum at the university of oklahoma in norman, oklahoma, with fifteen expert participants in attendance. participants were selected in consultation with an advisory board, with the intention of recruiting a diverse group of national experts in representative fields, including academic librarians, researchers from a variety of disciplines, and commercial game designers and software engineers. the conveners used nominal group technique to generate research data for this study.39 nominal group technique is a consensus-building method for achieving general agreement on a topic through face-to-face small group discussions and it “empowers participants by providing an opportunity to have their voices heard and opinions considered by other members” in a structured format.40 this method was adopted in order to reveal key challenges related to the visualization and analysis of 3d and vr data and strategies for designing and managing library programs to support these activities. data were generated through community note taking using google drive documents designated for each forum session. at the end of each discussion session, a group note taker summarized and presented the views of each small group to the wider forum. both the raw, community notes and the summarized, facilitator notes were collected and analyzed. notes produced from the smaller groups and from the larger group form the basis of the findings. one discussion topic, “course integrations and measuring impact on student learning ,” was open to the public during the “public forum” portion of the forum on the afternoon of the second day (see the “findings from the public forum” section, below). while these additional attendees were not given the opportunity to participate in the collaborative note taking, participants in the public forum provided anonymous responses to a set of questions on index cards that they submitted to the research team. data analysis consisted of grouping data from the community note-taking documents into higherlevel categories based on the research questions and emergent themes, following an inductive analysis approach. a central part of the data analysis process involved moving from grouping specific examples of institutional practices and personal perspectives in order to link them to more general, community-wide phenomena. in this way, a set of shared challenges and strategies could be identified at the community level of analysis. while there was a range of institutional and professional perspectives presented by the forum participants and the intention was to present a diverse set of perspectives on the topics covered in this forum, one limitation of this methodology is that it is limited to small groups of experts, which information technology and libraries | december 2019 31 could potentially exclude other perspectives. the inclusion of the public forum, including more participants from a greater range of institutions, helped to mitigate this limitation. we validated these findings by disseminating drafts to participants and asking them to correct, cl arify, or elaborate on the contents. the authors incorporated all participant feedback into a subsequent draft. this project was approved by the institutional review board of the lead organizing institution, virginia tech. findings this section discusses the forum findings and aligns them with the project’s research questions. rq1: what are effective strategies for addressing common challenges faced by academic libraries as they set out to implement 3d and vr programs? findings for research question 1 (rq1) are broken down into three main areas: (1) humancentered design challenges, (2) initiating vr programs in libraries and schools, and (3) curriculum and research integration and assessment. human-centered design challenges participants agreed that, in many ways, virtual reality is still an immature technology, which is reflected in shared experiences of forum participants, such as encountering simulator sickness and interface learning curves. as simulator sickness results from, among other things, a graphical rendering performance shortfall that leads to a disconnect between what the eyes and inner ear perceive, or an unnatural locomotive user interface (ui) decision on the part of content creators, the importance of graphics card and software selection (above and beyond their educational value) was emphasized.41 adding in-app spatial reference points—such as a virtual horizon line— was mentioned as a quick solution for the disorientation some users experience when engaging with virtual environments. practical solutions were provided for some of the most common issues related to the academic use of vr, including providing ginger candy and personal mirrors, as well as defining reasonable time limits per person for in-headset time, to help with motion sickness as well as self-consciousness that follows the removal of a headset (i.e., mussed hair) that is experienced by some users, particularly students. further, while not physiologically discomforting, instances of self-consciousness have been known to interfere with the educational effectiveness of virtual reality at the k-12 level, and methods for mitigating that experience—with the deployment of small mirrors, to check one’s appearance after a headset session, for example— were discussed by forum participants.42 most vr systems are able to provide both sitting and standing experiences. standing experiences are particularly valuable insofar as full-body interface mechanisms allow users to engage their whole bodies in interacting with vr systems, which provides a close correspondence between a user’s physical movements and their navigation of the virtual space. this decreases the learning curve of vr learning experiences, since the traditional alternatives—a sometimes tricky controller schema or command line interface—often require software or discipline specific training. in the case of seated vr systems, the system is able to accommodate users with disabilities. not only are students, faculty, and staff with disabilities able to engage with vr content, but also the vr technology can provide heretofore impossible learning experiences by providing lifelike access to scenes that are physically inaccessible to them. while these possibilities are promising, participants agreed that further work needs to be performed to accommodate often overlooked barriers to accessibility. examples of early techniques used to successfully address accessibility challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 32 https://doi.org/10.6017/ital.v38i4.11075 concerns include the mirroring of controller mappings to allow for use by either hand, the integration of accessible interfaces such as the xbox adaptive controller, and the creation of opensource developer tools that can virtually adjust for a range of visual impairments.43 regarding specific vr hardware currently available on the commercial market, participants were quick to point to common factors that limit the approachability, use, and scalability of university or library-based virtual reality. one critical concern was the cost of vr equipment; at the high end, oculus rift, htc vive, and assorted windows mixed reality headsets require a tethered connection to a dedicated personal computer (pc), and designated pcs must be outfitted with graphics cards that start at ~$300 (us) and increase rapidly from there. to sustain the performance necessary for a stable and comfortable virtual experience to the end user, a $500 graphics card coupled to another $500-$1,000 worth of computing hardware (e.g., cpu, motherboard, storage, monitor, etc.) is necessary, in addition to the purchase price of the vr headset. cost-wise, high-end vr remains a prohibitively expensive endeavor outside of wellfunded research institutions. while cost was mentioned as a major cause for concern, the physical constraint to user movements due to the wiring that connects the vr headset to the pc impedes one of the primary features of the technology, positional tracking of user movement. the importance of positional tracking, the ability to track a user’s headset and hand controllers along the six axes of motion as the user moves through physical space, means that interfacing with vr is ideally an intuitive, “natural,” and immersive experience that can be easily disrupted if the user encounters cables or other restrictions to their movements. fortunately, the major headset manufacturers mentioned above are starting to release more affordable, untethered, positionally tracked vr devices with increasing quality, which suggests that institutions ranging from k-12, to community colleges, to r1 research universities and academic libraries will soon be able to adopt immersive visualization technologies without encountering significant financial or ergonomic problems. 44 forum participants also noted that the same real-world fidelity that makes virtual reality an impressive learning platform can also produce harmful and disturbing effects. indeed, many of the most popular vr titles are violent, action-oriented “first-person shooters,” or multiplayer chat rooms in which very little attention is being paid to regulating abusive language. moreover, there are some educational or training applications that, while culturally and politically sensitive, are nonetheless unsettling in a high-fidelity virtual environment. disturbing places or objects can also negatively impact users; for example, phobia training applications in virtual reality, such as fearlessvr, might require academic institutions to deploy disclaimers prior to use at the risk of disruptive or damaging reactions from users (http://www.fearlessvr.com/). finally, forum participants discussed ways in which earlier design paradigms have subtly influenced the design of 3d/vr applications. participants noted that while libraries and librarians might immediately assume that a books-on-the-shelf virtual library is a good way to invest time and development resources, the technology affords the means to interact with not just text-based materials (or the spines of books, in the case of browsing activities), but richly detailed “source material” (3d objects of study) as well. in the case of design principles, the entire body can be incorporated into wholly new search and discovery mechanisms that build on the best aspects of the library browsing experience while incorporating novel content types. http://www.fearlessvr.com/ information technology and libraries | december 2019 33 initiating vr programs in libraries and schools participants identified a variety of challenges associated with initiating vr programs in libraries and schools and a set of strategies for addressing these challenges. they discussed the challenges of developing curricula, the importance of management plans, the impact of particular institutional landscapes on the success or failure of 3d/vr initiatives, and offered some insight on the experiences of other information institutions, such as museums, that may be helpful to consider when developing broader strategies. one emergent theme emphasized the challenges of developing curricula—specifically, customized 3d/vr teaching modules. some participants noted that the expertise needed to develop these learning modules is unevenly distributed across the university, which makes it difficult to develop these critical teaching components. furthermore, finding and funding technical expertise is a significant challenge, and participants discussed the difficulties in balancing the investment in untested technologies with the potential benefits of those same technologies. untested technologies may be difficult to maintain and may require buy-in from administrators. another challenge is the difficulty in getting researchers to share their project outcomes for use in instruction. researchers who develop vr tools or content may not want to share the products of their labor because they perceive them to be integral parts of their research agendas, or they may feel that the products of their projects may be so customized that they will not be useable by other researchers. finally, participants in the forum pointed to the general bottleneck of content creation for 3d and vr, which impacts the development of teaching curricula and the production of research-quality 3d data. more specifically, they noted that better workflows need to be developed in order to make it easier to create their own 3d models and to acquire and work with 3d models created by other researchers. participants pointed out that a lack of easily accessible content will likely limit investment in vr programs and integration into curricula, which suggests that support for sharing content between and within institutions could be an important way of promoting the adoption of these new technologies. forum participants discussed how developing management plans for 3d/vr hosting spaces is essential to ensure successful initiation of vr programs. participants offered a range of models for overseeing user engagement with vr equipment, including placing the equipment in a makerspace-like environment that was always monitored by staff; keeping the space locked with the option for users to request a key; as well as implementation in a fine arts space that has its own operating hours and security staff to oversee public engagement. indeed, the question of staffing spaces emerged repeatedly throughout the proceedings, with the idea of using student staff from the host university or college as an effective and inexpensive means of o verseeing 3d/vr spaces, assisting users, and troubleshooting technical issues that are typical of these new and emerging technologies. students were also identified as potential content creators for those spaces and promoters of the 3d/vr programs to their peers. the institutional landscape of the school hosting the 3d/vr program was also identified as an important factor that can impact 3d/vr adoption, since administrators can play a big part in helping or hindering vr implementation. participants noted that they needed to explicitly justify the time and return on investment for vr in less supportive environments, which is not surprising given ever-tightening budgets across universities. faculty support also impacts vr program initiation. while a handful of faculty members may be willing to superficially explore vr technology and try it out in one of their classes, wider adoption will require the provision of challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 34 https://doi.org/10.6017/ital.v38i4.11075 measurable student outcomes. however, the biggest challenge noted for getting faculty to support vr initiatives was convincing them that it could be useful for their research. participants from museums that are implementing vr or augmented reality (ar) technologies also offered some insight into institutional challenges of these technologies. some museums are creating 3d scans of historical items, which raises a number of concerns about the accuracy of the models and how that impacts the meaning of the 3d models in the context of a museum’s wider collecting mission. museums want to create 3d content that is historically accurate, while at the same time being optimized for use in vr and ar applications. the biggest challenge identified is how to make the technology affordable while also maintaining its usefulness to communities of museum visitors. this aligns with concerns expressed by libraries, which also find balancing cost and usability to be a key concern. participants from across institutions offered strategies for addressing some of these challenges. first, participants noted that training sessions can provide an important introduction to vr for students and faculty that enables them to have a good initial experience and see the value of vr beyond its novelty. without proper orientation, users could have an unpleasant initial experience, which could unnecessarily sour them on using vr in the future. second, participants suggested several demonstration techniques for introducing a wide range of university and library community members to the new technology and exhibiting it in a positive light. “road shows,” i.e., taking the technology to other parts of campus or different communities, can be very useful for reaching users who may not otherwise come into the library to engage with emerging technologies. library-hosted events, such as hackathons, workshops, and demonstrations can also help to develop interest among current library patrons. providing mobile workstations for classroom use or individual patron checkout can also make the technology more accessible. these strategies suggest the importance of convincing potential users of the benefits of 3d/vr for their particular interests or research needs. curriculum and research integration and assessment integrating 3d/vr technologies into established research and teaching conventions and workflows has proven to be a challenge, and all participants reported continued struggles to establish ways to assign credit to the creators of 3d/vr content, and methods of rigorously assessing the impact of this content on learning outcomes. regarding tenure and promotion concerns, it is not clear how faculty outside of technologically oriented or applied science disciplines might communicate and track their use of vr as a tool in their courses or research for inclusion in their tenure and promotion portfolios. creating vr experiences represents a substantial investment of development resources and faculty time, and the experience itself—while distributable and citable—is not typically treated by the research community as a scholarly output. this is symptomatic of the relatively immature content ecosystem (i.e., a scarcity of educational vr software and scholarly 3d content), which necessitates either custom software development or forces researchers to use off-the-shelf tools that may comprise “blackboxed” data transformations or offer limited functionality. to address this current lack of fully developed educational software and the necessity of assembling 3d/vr course modules piecemeal, participants concluded that the best place to start the integration process would be by establishing “first principles,” or what is known for certain regarding the strengths and weaknesses of vr. faculty members who want to include a 3d/vr information technology and libraries | december 2019 35 component in their teaching or research agenda should familiarize themselves with the key benefits of the technology that transcend disciplines and that are supported by evidence-based assessment. faculty should select task types for their learning activities that lend themselves to vr visualization, and deploy course (or research) content that, due to fragility, distance, rarity, or scale are relatively inaccessible. forum participants discussed how the benefits of 3d/vr in terms of a particular instructional goal or research initiative should be judiciously weighed against the relative cost of purchasing, installing, and maintaining what is still an immature, fast-changing set of interrelated content creation, visualization, and output (e.g., 3d printing) technologies. moreover, once these technologies are deployed, and learning outcomes or research goals that align with the documented benefits of the technology are identified, assessment strategies should be deployed to evaluate the impact of these tools. measuring performance, engagement (e.g., measuring time-ontask), comparative economic benefit (i.e., with respect to traditional course content delivery methods), and qualitative variables, such as impact on student self-efficacy, are all useful approaches for measuring the impact of vr in a research or teaching environment, and thereby may assist in justifying the expansion of these programs and tool sets. rq2: how are academic librarians using vr to support existing library services, such as curriculum development and access? participants discussed a number of applications for vr and related technologies that could help expand library services, including new ways of browsing and engaging with library resources, circulating vr equipment, and offering entirely new types of library services. some applications that were brought up included using ar to develop virtual books and book “trailers” that display promotional materials for each book as the patrons browse the stacks with their ar-enabled device. using vr to engage with the materiality of books was also suggested. participants gave examples of using vr to look closely at medieval manuscripts, rare books, and artists books in order to observe their spatial properties, such as indentations, surface detail/topography, ink, and other material aspects.45 other participants suggested that vr could be used to compare and recontextualize library collections across geographies, placing the books in the contexts in which they were found and enabling comparative analysis of textual features. participants also suggested that vr could be used as a platform for presenting numerical data, which could have applications for researchers who analyze data through already established visualization services at academic libraries. the discussion around expanding access using vr brought up the idea of libraries hosting 3d/vr collections, which could contain 3d scans and vr environments sourced from locally produced content and would be shared by 3d-scanning partners around the world. one question that was raised was how to store the 3d content in a way that it could be easily transferred to vr systems for access. participants from the university of oklahoma discussed their work hosting multi-campus vr walkthroughs of 3d scans of historic sites (e.g., the arches of palmyra, syria), which offered an evocative example of how libraries can simultaneously provide access to technology, create and curate collections of scholarly 3d-scan data, and present expertled events.46 this shows how libraries hosting vr technologies can both be technological and intellectual partners in presenting 3d content to library patrons. participants also pointed out how vr could be used to contribute to ongoing efforts in the library community to develop tools challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 36 https://doi.org/10.6017/ital.v38i4.11075 for linked open data and bibliometrics by creating new ways of visualizing networks of relationships between texts. these examples suggest that vr could be used as a multidimensional visualization platform that would visualize relationships between texts and areas of knowledge in rich and immersive ways, yielding new insights for librarians, library researchers, and other users.47 a circulation model of vr deployment was also discussed and found to be successful at several institutions. this typically followed a traditional “checkout” model of using the circulation desk to loan equipment for patron use for a limited time period. some libraries check out all the vr pieces separately, while others are experimenting with full vr kits. circulating vr equipment brings up a number of challenges, such as hygiene concerns, theft and loss of equipment, the cost of licensing and scaling up software purchases, and managing software accounts and updates. adopting a circulation policy for vr may help to ensure the sustainability of the program by centralizing cost, risk, and point of access. however, centralization may not always be the most appropriate solution as it can turn off some faculty and discourage their interest in using it. a final challenge of circulating vr hardware is the bottleneck of content creation, such that libraries find it difficult to provide new content for vr, which may make it difficult to sustain user interest over time. some participants pointed out that without a game design curriculum or other creative programs on campus that have the capability of developing new content, users may lose interest, which would limit the success of a circulation-based model. if programs do not have access to the knowledge and tools necessary to develop vr content, it becomes difficult to expand services for development and pilot projects. it is therefore critical to form partnerships early on with content creators when developing vr programs. rq3: how can the knowledge and resources of academic, library-based 3d/vr programs be shared with other academic and information organizations, such as public libraries and regional highereducation institutions? based on participant discussions, several areas of concern were identified that need to be addressed in order for 3d/vr knowledge and resources to be shared with a broader range of institutions: methods for collaborating and coordinating across institutions; strategies for addressing development and hardware resource limitations; and addressing challenges to the widespread adoption of 3d/vr tools in higher education. methods for collaborating and coordinating across institutions collaboration and coordination across institutions was found to be important for ensuring that vr tools are made available to both large and small institutions. few small colleges, cultural heritage institutions, or public k-12 school districts have the financial or technical resources to deploy educational vr at scale. the hardware and software used for educational vr require expertise—in the form of hardware setup, maintenance, administrative capabilities, and software development experience—represents a significant investment in labor (i.e., staffing overhead) and training on the part of research institutions, such as those participating in the forum. forum participants agreed that, given the disproportionate concentration of expertise within higher education, initiatives should be undertaken to ensure that tools, workflows, training, and support are provided to organizations outside of academia. a consortium model was suggested as one formal mechanism for addressing this concern. information technology and libraries | december 2019 37 strategies for addressing development and hardware resource limitations in the case of software or content, forum participants emphasized the value of open-source and open-access standards for facilitating the widespread distribution and use of educational vr content, especially for those without the development resources to create their own content. participants suggested an open “app store” like ecosystem to assist in the distribution of this educational content across organizations. to aid in the successful integration of apps from a central database, participants discussed the prospect of supporting collaborators remotely, perhaps even from within vr, essentially training others on the software using the strengths of vr hardware. finally, participants identified several large content-hosting platforms that host a variety of 3d assets relevant to education which might readily be deployed in vr without extensive development resources. a sandbox or open-ended viewing environment for loading and analyzing arbitrary sets of user-generated 3d models could be provided by the university or academic library, such that the end user would experience 3d-learning objects that were selected and deployed by local educators without the need for software development expertise.48 in contrast to the high-end vr workstations (e.g., oculus rift, htc vive, etc.), participants were quick to point to the relative affordability of smartphone-based vr solutions. these google cardboard–type implementations are especially promising, given the widespread adoption of smartphones with sufficient computing power to render interactive educational 3d content stereoscopically. in the case of sketchfab, a commercial 3d-hosting platform, web-based 3d assets can be uploaded, collected, and accessed from any current smartphone device, and launched quickly into a stereoscopic viewing experience. in this way, more users at a wider variety o f educational institutions can make use of some of the uniquely beneficial platform characteristics of vr (e.g., depth cues) without committing to the purchase of high-end vr workstations. addressing challenges to the widespread adoption of 3d/vr tools in higher education library technologists want to introduce vr to a wide audience of potential beneficiaries, yet this approach may cause faculty to dismiss such implementations as a novelty. forum participants repeatedly discussed the importance of involving faculty in implementations of vr tools and spaces that have academic value. participants noted how the uptake of 3d/vr technologies can be thwarted when faculty are disinterested or are not well-informed about the potential uses of 3d/vr technologies. forum participants noted that university faculty who want to incorporate 3d/vr technologies are faced with many of the same challenges encountered by smaller educational organizations, including lack of guidance on setup and maintenance, administrative pushback, and high cos t. participants agreed that academic libraries should play a critical role in the hosting and administration of these systems. deployment of 3d/vr technologies in academic libraries would provide a central resource that could be used by many departments, including those fields that may lack the resources to invest in their own equipment. moreover, since librarians already act as research and instructional collaborators with faculty, those relationships can be drawn upon when adopting vr, and showcasing faculty engagement helps to demonstrate the academic value of 3d/vr technologies for library and university administrators. further strategies for collaborating across organizations interinstitutional collaboration was put forward as a means to begin addressing the challenges facing both universities and smaller educational organizations seeking to implement 3d/vr programs. participants agreed that it was incumbent upon the larger universities or institutions to challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 38 https://doi.org/10.6017/ital.v38i4.11075 provide open access to their vr software projects and provide the mentorship and training necessary to successfully deploy these applications for use by smaller institutions. forum participants suggest that, in some cases, this will require a physical visit to a collaborator’s location and live demonstrations of tools and techniques. alternatively, a showcase or summit event could be hosted by large institutions for the purpose of demonstrating 3d/vr technologies to a number of small institutions. at such events, during site visits, or within vr-based training sessions, best practices and the results of empirical research on the efficacy of 3d/vr could be communicated to smaller organizations. one such institution type, public libraries, was discussed in relation to the potential value of collaborative outreach. even with limited budgets, public libraries are trying to bring 3d/vr technology to their patrons. they would benefit from becoming strong collaborators with local universities and colleges. for example, summer programming at public libraries could be organized to effectively distribute the software, standards, best practices, and workflows being pioneered at the university level. forum participants suggested a “hand me down” program for donating earlier generation headset hardware, which is replaced quite frequently and at great expense, but is typically still functional. in this case, smaller organizations would benefit from surplus equipment funded by research grant money or donor contribution, both of which are less common at the public-library level. along with the open-access software and 3d-asset ecosystems discussed above, this sharing of hardware and knowledge would increase the impact of 3d/vr technologies across multiple organizations and institutions. findings from the public forum the public portion of the forum consisted of a half-day, afternoon session attended by local stakeholders from other academic libraries, public schools, public libraries, and other institutions in oklahoma, texas, kansas, and arkansas. they were invited to attend and engage in discussions with the invited experts on the topics of 3d/vr in relation to smaller institutions, such as public k12 schools and public libraries. the following section reports on findings from that session, drawing on a set of 38 anonymously completed notecards that participants filled out during the public forum and returned to the project team. for these notecard responses, participants were asked to answer the following three questions: 1. what challenges do smalland medium-sized, public-facing institutions face when implementing vr? 2. how can large institutions support smalland medium-sized institutions who are starting to adopt 3d/vr? 3. what options are there for public libraries or k-12 to participate in 3d/vr workflows? the following sections summarize those responses and the key themes from the public forum discussion. challenges faced by smalland medium-sized institutions public forum participants identified challenges related to cost (including equipment, maintenance, and staffing), content creation, and faculty/administrator buy-in as the top concerns facing small to medium-sized public institutions looking to deploy educational vr. regarding cost, it was clear that budgets for innovative, unproven technology that may become quickly obsolete were oftentimes nonexistent, and those local vr champions who sought to install such technology faced pushback from administrators who do not understand the technology and are focused on information technology and libraries | december 2019 39 measurable returns on investment rather than exploratory offerings. finally, staffing was a challenge identified and shared by multiple public forum participants. to hire, train, and support skilled staff members who are expected to keep abreast of ongoing developments of a still young technology such as vr requires a sustainable investment from administrators. participants noted that even having skilled staff in place and access to the necessary equipment, the success of a given vr deployment was not guaranteed. one potential bottleneck identified by public forum participants was vr content creation. due to the relative immaturity of the vr software marketplace and its associated disorganization, public-forum participants described focusing their efforts on supporting local content-creation efforts by students, faculty, and staff. beyond recognizing the need to hire and support costly development workers, public-forum participants also noted how the preservation and further distribution of locally produced vr content require skills and training beyond their level of expertise. oftentimes, these smallto medium-sized public institutions have a single staff member, who may not have all of the required technical skills, tasked with deploying and developing vr content, which limits the local impact of this potentially transformative educational technology. finally, multiple public-forum participants identified the need to garner faculty buy-in as a recurring challenge. oftentimes faculty do not know about the technology or have a limited understanding of it. to overcome this, public-forum participants noted that a demonstration of vr’s value is critical. they suggested that this demonstration might be accomplished in partnership with larger educational institutions (e.g., universities), whose own staff, content, and expertise could be leveraged to best communicate the value of vr to local administrators and faculty. ways larger institutions can support smaller ones beyond assisting smallto medium-sized public institutions in demonstrating the value of vr for local faculty and administrators, public-forum attendees suggested that the continued development and distribution of open-source vr software, providing help with setup and maintenance issues, and engaging in formal knowledge distribution activities—in the form of conferences, consortia, and grant partnership—would streamline the adoption of vr by these smaller public institutions. public-forum participants also expressed a desire to engage with the research outputs of larger institutions that focused on the efficacy of vr, which may be useful for working with local faculty and administrators. software sharing was specifically identified as a way that larger institutions could support the early efforts of smallto medium-sized institutions as they set out to deploy and integrate vr. participants were careful to note that additional support, in the form of training and troubleshooting, was equally important to the distribution of the software itself. the affordability of vr software was described as a particularly important issue by a number of participants, hence the focus on open-source solutions by the group. predicting inevitable hardware and software failures, public-forum participants communicated that onsite support by vr experts from larger institutions would be ideal. participants noted that, while knowledge sharing is important, guidance on how to set up a specific system sometimes requires onsite support. fortunately, there are novel support mechanisms supported by the technology itself, with public-forum participants suggesting that experts could be “brought in” to provide support in the virtual environment itself. in this case, a multiplayer vr experience similar challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 40 https://doi.org/10.6017/ital.v38i4.11075 to those demonstrated by the content developers in attendance could function as an interactive learning platform for the distribution of information and would even provide training on the technology. ways public libraries and k-12 schools can participate in 3d/vr the size and diversity of the public library and k-12 user communities were reflected in the feedback provided by public forum participants concerning ways in which these types of institutions can participate in vr. participants suggested that within public libraries, focus groups that represent different ages, physical ability levels, and socioeconomic backgrounds of library users can be recruited to test and refine vr offerings. in this way, the wider public can be introduced to vr technologies and made aware of their benefits. the potential for k-12 students to assist in the vr-content development process, which could have the added benefit of helping students develop valuable technical skills, was also mentioned as a way that these institutions could participate. this programming need not start out as a formal curriculum, participants suggested, but rather as an afterschool program, taking the form of a “modern day a.v. club,” as one participant suggested. public-forum participants identified the need for compensation or incentive programs for those adolescents in public libraries who are wishing to contribute to the content creation process. overall, participants in the public forum provided positive feedback about their experience at the event: “very useful indeed. i learned a lot,” wrote one participant. “it’s nice to hear perspectives of those working in academia and to share our own perspectives . . . ” wrote another public-forum participant. a third participant was enthusiastic about the future, writing: “i love the idea of libraries being partners.” these responses indicate the importance of collaboration between small and large institutions and the value of these types of public forums for sharing knowledge in this field. summary of findings & discussion the findings drawn from the discussions and presentations at the forum offer a broad view of the current concerns of this diverse community involved in implementing 3d/vr in academic institutions for the purposes of education and research. the range of stakeholder groups is expansive and demonstrates a growing interest in immersive visualization technology across many fields and institution types. by reviewing previous literature in conjunction with the group discussion findings, we can identify and summarize a set of common challenges facing libraries and other information institutions that are implementing 3d/vr technologies. in the following section, we describe these challenges or considerations identified for each topic and point towards possible strategies or directions forward for addressing them. initiating vr programs in libraries and schools the main challenges facing libraries and schools as they initiate vr programs include developing interest and awareness for the emerging technology among faculty, students, and administrators; locating necessary expertise in vr within their communities when knowledge is unevenly distributed; getting enough buy-in from administrators to support the allocation of necessary resources; encouraging researchers to share their projects and research outputs for the benefit of the larger community; and overcoming the bottleneck of vr content creation as a limiting factor information technology and libraries | december 2019 41 on institutional investment. from the findings we can identify a set of strategies to begin to address these issues, including: • utilize demonstration techniques to generate student and faculty interest in vr (e.g., “road shows” and library-hosted events, such as hackathons, workshops, and demonstrations). • develop replicable workflows that can be implemented by a variety of stakeholders. • establish management plans for 3d/vr hosting spaces that include using student labor for overseeing vr technology spaces and content creation. • develop and validate metrics for evaluating the impact of vr technologies in order to provide evidence for faculty and administrators that vr is worth their time and investment. integrating vr into research and teaching from the findings, we can also identify a number of challenges related to integrating vr into research and teaching. one of the major challenges in this area is related to the research community not valuing vr projects as scholarly or pedagogical outputs. because of this, faculty members are typically reluctant to invest their time and resources into developing vr curricula if it will not contribute to their tenure and promotion portfolios. related to that problem is the issue of assigning credit or attribution to 3d/vr learning objects when they may be developed by teams, which can discourage sharing and limit reuse of vr learning modules. finally, because of a lack of metrics for measuring the impact of 3d/vr on student learning, it has been hard for faculty to rationalize integrating what is sometimes perceived as unproven technology into their classes. determining which metrics to use has pedagogical as well as economic implications, since without metrics, it becomes difficult to rationalize the expense of 3d/vr to institutional administrators. participants did not have strategies for addressing all of these challenges, but offered the following suggestions: • design vr course integrations that take advantage of the particular access and analytic characteristics of vr technologies. • weigh instructional goals with the cost of vr equipment and development time. • develop assessment strategies and define metrics for evaluating the impact of vr learning activities on students. expanding the role of the library with vr the group agreed that libraries are ideal places for hosting 3d/vr equipment, services, and support because they are often centrally located in their communities and they can potentially help by centralizing the risk and cost of untested technologies. participants identified a number of new techniques for utilizing the benefits of 3d/vr to expand existing library services, such as offering new ways of browsing and engaging with existing library resources, enabling the development of 3d-based digital collections and curated exhibitions and events that draw from those collections, and adding vr-visualization equipment as another piece of digital technology that libraries can circulate to support the various uses of the range of patrons interested in this technology. again, although there was no lack of big ideas in regards to how 3d/vr could exp and library services, the biggest challenges for libraries adopting 3d/vr into existing services was still a lack of verified educational content, which confirms the dire need to share 3d/vr content within institutions and across the wider community. without platforms for sharing 3d/vr content and the appropriate institutional and disciplinary incentives to do so, 3d/vr is unlikely to be adopted broadly and the range of exciting new applications will not be realized beyond niche projects. challenges and strategies for educational virtual reality | cook, lischer-katz, et al. 42 https://doi.org/10.6017/ital.v38i4.11075 collaborating and coordinating across institutions based on the findings drawn from both the expert-led and the public portions of the forum, it is clear that collaboration and coordination across institutions is essential for making 3d/vr a widely successful educational and research tool, because it can enable the sharing of resources with a range of smaller institutions that would otherwise not be able to adopt the technology on their own. supporting this exchange will require providing faculty at larger institutions with the necessary tools and incentives to support that sharing, which is an area in which participants agreed that academic libraries could serve as the needed source for technical knowledge and equipment. in summary, participants identified the following approaches for supporting efforts at collaborating and supporting smaller institutions and expanding access to underserved communities: • larger institutions should provide tools, workflows, training, and support through on-site visits. • universities should partner with public libraries, since they can be hubs for providing access to communities that would otherwise not have the opportunity to engage with 3d/vr outside of academic communities. • use open-source and open-access standards and content, including an open “app store” ecosystem of 3d/vr content. • use existing databases of free 3d content. • use affordable smartphone-based vr applications when more expensive vr systems are not feasible. these findings contribute to current discussions in the field of library innovation that consider how libraries can adopt and sustain emerging technologies, such as vr and 3d technologies.49 we have identified a set of common challenges and possible strategies for integrating 3d/vr programs into libraries and educational institutions, but additional research is required in this area to produce more detailed workflows for a range of institutional types to follow. there are inherent limitations to any specification, since every context has its own specific requirements for 3d/vr implementation, but as these findings suggest, there are common challenges that can be addressed in systematic and generalizable ways. these findings offer some examples of this, but additional data collection is necessary to focus on some of the key areas that are still developing. conclusion the overriding theme across the findings from the forum is the importance of interinstitutional and interdisciplinary collaboration. confirming what we had assumed going into this project, it is clear that many of the challenges of 3d/vr can only be solved through systematic and concerted effort across multiple stakeholder groups. 3d/vr is not limited to a niche area. as we can see from the range of participants and applications, it has broad transformative potential and is becoming increasingly mainstream in many contexts. this suggests the importance of addressing these challenges through additional forums and working groups to generate standards and best practices that can be applied across the growing 3d/vr community. such guidance needs to be specific enough that they can offer practical benefit to stakeholder groups of varying capacities, but flexible enough to be useful for a range of applications and disciplinary practices. information technology and libraries | december 2019 43 while the findings from the forum suggest a variety of techniques and strategies for addressing the challenges identified, there is still much work that needs to be done to establish standards and best practices, generate institutional support, and enact change within disciplinary cultures in order to better support these communities. in particular, the following areas require further inquiry: • develop validated metrics for evaluating the impact of 3d/vr, from pedagogical, research, and institutional perspectives. • develop guidelines and tools for supporting users with disabilities. • support smaller institutions in initiating and supporting 3d/vr projects. • find ways to educate skeptical disciplines about the value of research and teaching that uses 3d/vr. • develop tools for supporting 3d/vr throughout the research or educational lifecycle, including: o project management and documentation tools; o universal 3d viewers that integrate with vr equipment and 3d repositories; o sustainable, preservation-quality file formats for 3d and vr; and o open platforms for hosting 3d/vr content. there are a number of other projects that are addressing some of these lingering challenges within the field of 3d and vr research and teaching, including community standards for 3d data preservation (cs3dp), an imls-funded project that is using a series of meetings and working groups to develop community-sanctioned standards for preserving 3d data in academic contexts (http://gis.wustl.edu/dgs/cs3dp/); building for tomorrow, another imls-funded project that is developing guidelines for preserving 3d models in the fields of architecture, design, architectural archives, and architectural history (https://projects.iq.harvard.edu/buildingtomorrow/home); the smithsonian institute’s 3d digitization program, which is developing workflows and metadata guidelines for a variety of 3d creation processes (https://3d.si.edu/); and the library of congress’s born to be 3d initiative, which has started convening experts in the field to look at the preservation challenges of “born digital” 3d data, including cad models, gis data, etc. (https://www.loc.gov/preservation/digital/meetings/b2b3d/b2b3d2018.html). the lib3dvr project team will continue to collaborate with members of these project teams to ensure that knowledge is shared and that any standards and best practices that are developed for 3d/vr visualization and analysis take into consideration the findings from this forum. the project team is confident that through these initiatives, useful standards and best practices will emerge to assist educators, researchers, librarians, technologists, and other information professionals address the complex challenges of implementing 3d/vr visualization and analysis for scholarly and pedagogical purposes in their institutions. notes 1

... zillner, tom information technology and libraries; mar 2000; 19, 1; proquest pg. 54 book reviews information ecologies: using technology with heart by bonnie a. nardi and vicki l. o'day. cambridge: mit pr., 1999. 232p. $27.50 (isbn 0-262-14066-7). the media equation: how people treat computers, television, and new media like real people and places by byron reeves and clifford nass. cambridge: cambridge univ . pr., 1996 and 1999. 305p. $28.95 (isbn 1-575-86052x); paper, $15.95 (isbn 1-575-86053-8). the books i am reviewing this month are interrelated because they both focus on information technology and our changing world, with the two volumes looking at different levels of the picture. the broader, and to me more intriguing, view is presented by nardi and o'day in their wonderful book information ecologies. although it is not clear from the capsule biographies of the dust jacket, nardi and o'day are anthropologists who study the world of technology in a number of locales, and they here report the findings from their field work. among the case studies they discuss are an examination of the activities of reference librarians at two corporations and a look at a virtual world created for and by elementary school students. but they do much more than simply present case studies, although these alone make the book a worthwhile read. in addition, they argue that the most useful way to look at information technology is through the metaphor of "information ecologies," "system[s] of people, practices, values, and technologies in ... particular local environment[s]." they adopt this biological metaphor after carefully considering the most commonly employed information technology metaphors: technology as tool, text, or system . in turn, they find each of these metaphors wanting. it is particularly important to choose carefully the metaphorical lenses through which technological developments are viewed. each particular metaphor has consequences for how sanguinely we view a technology, and it is often worthwhile to use multiple metaphors to enhance our world view. the information ecology metaphor is particularly appropriate for an anthropological view of local "habitats" and their inhabitants and artifacts . in turn, an anthropological view is particularly apt for capturing the human side of technology (thus the subtitle: using technology with heart). this is a side of things that can be overlooked in other metaphorical views, particularly since it requires that the sticky issue of values be considered. unfortunately for all of us, there is a reluctance to talk of human values when considering technology. as nardi and o'day note, there is a tendency to either enthusiastically applaud new technology without regard to its effects, or to condemn all new technology as inherently debasing to humanity, or to simply resign oneself pessimistically to the inevitable development of technology and our lack of control over it. nardi and o'day tend to be cautious optimists, claiming that we can control technology, and the way to exercise that control is through our own local encounters with information ecologies. thus, rather than bemoaning the dehumanizing effects of the internet, information ecologies explores the successful use of internet technologies to set up a virtual world for students and the elderly in phoenix, arizona. instead of thinking or acting globally, exploit the technology locally, but do so in a way that makes sense in terms of human values. on the taxonomic scale of technology views, ranging from gloom and doom (e.g., the views of clifford 54 information technology and libraries i march 2000 tom zillner, editor stoll) to perpetual optimism (e.g., nicholas negroponte), i place nardi and o'day somewhere in the middle, but as i suggested, leaning toward cautious optimism. in fact, they spend several chapters discussing the views of others and offering prescient criticism of the deficiencies of those views . of particular interest to me was their analysis of the french sociologist jacques ellul, who apparently sounded the alarm concerning the stress to mind and soul of constant technological change in 1954, well before the current crop of doomsayers. nardi and o'day find ellul's views, as articulated in the technological society to be compelling. yet, they claim, the rise of the internet can counteract the trend that ellul saw toward monotonous sameness and lack of diversity in the face of technological efficiency. perhaps so. one thing that i was looking for in information ecologies were some practical tools for engaging in the kind of exploration of information habitats that nardi, o'day, and other anthropologists engage in. there is a spate of interest lately in the role of anthropologists in the design and deployment of new technologies, and i would like to determine its applicability to my modest software development projects. unfortunately, i was mainly disappointed on this score. in fairness to the authors, they did not set out to spell out the anthropological methodology of exploring information ecologies in any detail. the purpose of the book is rather to argue that viewing the world of technology as a set of interconnected information ecologies is useful and accurate, and in many cases superior to other metaphorical views. they succeed in this goal. now i want them to go on to write a book on using anthropological methods in these ecologies without necessarily becoming a professional anthropologist. nardi and o'day do touch extremely briefly on a few conventions of interviewing subjects, with --------reproduced with permission of the copyright owner. further reproduction prohibited without permission. their most important technical discussion centering on what they call "strategic questioning," which they present in the context of evolving information ecologies . they provide useful categories of questions to be asked, and specific examples. although it may seem obvious to ask penetrating questions of members of an information habitat, this is one area in which software developers in particular fail miserably . another seemingly obvious pointer is to pay attention . again, its obviousness is deceptive , since most of us are poor observers who make many assumptions about the characteristics of a work activity without observational evidence . as evidence that people introducing new technologies to an ecology do not follow these simplest pieces of advice you can tum to the chapter "a dysfunctional ecology," to see how badly technology can fail for nontechnological reasons . this case study deals with a major teach ing hospital that introduced a monitoring system into its neurosurgical operating suites that captured instrument readings as well as complete audio and video. the system was installed to aid neurophysiologists, experts who are called in to advise neurosurgeons at key points during complex surgeries to ensure that patient neurological function is not compromised . the neurosurgeons and neurophysiologists at this hospital decided that it would be more efficient for the neurophysi ologists to be able to remotely monitor multiple surgeries simultaneously. both groups failed to consult with the other constituencies among the operating team, the nurses and anesthesiology staff. these groups believed that their privacy was being compromised, particularly since it was possible to tape any procedures at multiple workstations throughout the hospital. i can easily envision similar sorts of problems due to lack of communication in introducing new or modified technology into other milieus, e.g., libraries. although the consequences might not lead to the potentially life-threatening situations that could arise in an operating suite, there are certainly possible outcomes where service to users could be undermined. despite the book being not exactly what i (rather selfishly) want, lnformation ecologies is a first-rate read and an important starting point for those concerned with better controlling technological change in the world of information. turning from an anthropological point of view to a psychological one, the media equation offers another important basis for technological design and implementation, particularly of computer software and multimedia. the release last year of a paperback edition of this volume, first published in 1996, provides a convenient pretext for reviewing this work. reeves and nass have supervised years of study and experimentation that have consistently demonstrated the truth of what they call the "media equation": that our relations with media, including computers and multimedia, are identical in key ways to our relationships with other human beings. this is true of all of us, even those of us sophisticated enough to understand that we are dealing with devices and human artifacts rather than people . reeves and nass quite entertainingly present the technique they've used over the years to perform their research, on a step-by-step basis: 1. pick a research finding on how people respond to each other or their environment. 2. find the summary of the social or natural rule that the study has yielded. 3. replace the words "person" or "environment" in the summary with media of some sort (television, movi es, computers, etc.) 4. find the research procedure . 5. substitute media for one of the people or the environment in the procedure. 6. run the experiment. 7. draw conclusions. although this may sound facetious, it is in fact the recipe that produced the startling conclusions that we all tend to behave toward media much as we do toward other people. what's perhaps more important is that reeves and nass point toward techniques that practitioners can use to produce more effective media, including computer software . as a simple example, consider politeness. reeves and nass discovered that people treated computers with the same sort of politeness that they would other human beings, and in turn reeves and nass suggest that people respond better to "polite media." they then provide some fairly straightforward advice on producing polite computer programs, starting with grice's maxims, a set of politeness rules assembled by h. paul grice, a philosopher and psychologist. these center around truth telling, appropriate quantity of information (neither too much nor too little), relevance, and clarity. all of this is fairly unsurprising, but the authors spell out just how the maxims can be applied to the construction of computer programs . further, they go on to suggest some rules of thumb of their own. for example, some computer programs produce verbal output but expect the user to key in his or her responses. this may be perceived by the user , possibly subconsciously, as forcing an impolite response, since mixing communications modalities is a faux pas. thus, they suggest that if text input is required , perhaps only text output should be supplied . this should provide you with some of the flavor of the media equation, and in turn you may be able to see a set of potential ethical dilemmas that can arise from utilizing book reviews i 55 reproduced with permission of the copyright owner. further reproduction prohibited

messages could be inserted into new media to advertise products or to attempt to bolster employee morale. in fact, they say, " ... it might be easier to accomplish subliminal intrusions with a computer than with a television, because software can respond to the particular input of individual users and timing is more precise." they immediately temper this insight with the caution that" ... ethical and legal issues abound." indeed. although some of the techniques that can be applied to new media do lead to ethical problems, i think that most of what reeves and nass talk about are just elements of good design. subliminal suggestion seems to most of us to be out of bounds because it unfairly manipulates user response in a powerful way. the unfairness is that someone can be manipulated without his or her knowledge to do something outside of the person's normal behavior. although the other techniques tend to subtly alter behavior, they don't generally result in an anomalous action by the user. if you think this is a kind of philosophical hairsplitting, you're right. the onus is upon the programmer or multimedia designer to use these techniques with great care. in a past professional life i wrote computerized patient interviews for the psychiatry department of the university of wisconsin. researchers there and elsewhere found that people were generally more candid with the computer than they were with human clinicians. so the findings of reeves and nass were not quite as surprising to me as they might be to others. what did surprise me, however, is that the media equation is not a phenomenon solely of the nai"ve or inexperienced media and computer users. on the contrary, all of us, no matter how conversant we are with underlying technology, are susceptible to the effects described in the media equation. this vastly increases the power of computer programs and other media for both good and ill. i want to emphasize that not all of the possible effects of humanmedia interaction are pernicious. most are simply innocuous, and if techniques that benefit users can result from these effects there should be no harm in applying them in software or multimedia. in general, it's desirable to make user experiences of software and media pleasanter and more productive, and reeves and nass do an excellent job of providing pointers throughout the book. there are suggestions with regard to personality, emotion (including arousal), social roles, and form (e.g., image size, fidelity of sound, and video). none of them comes close to being as controversial as subliminal suggestion, although it continues to make me uncomfortable that people react to media as if they were dealing directly with other human beings. this is a disquieting finding, but it should not dissuade us from our jobs of designing good systems for users. all in all, information ecologies and the media equation are both firstrate books that belong in our libraries and on our professional bookshelves. both provide methodologies and techniques for making user interactions with automated systems a better experience, both in terms of accomplishing tasks efficiently and in terms of user satisfaction.-tom zillner index to advertisers info usa library technologies, inc. lita cover 4 cover 3 cover 2, 2 56 information technology and libraries i march 2000 microsoft

 impasse   between  libraries,  campus  it  departments,  and  academic  administration  over  authentication  issues   with  the  public  area  pcs  in  the  library.  this  research  takes  an  in-­‐depth  look  at  the  state  of   authentication  practices  within  a  specific  region  (i.e.,  all  the  academic  libraries  in  north  carolina)  in   an  attempt  to  create  a  profile  of  those  libraries  that  choose  to  authenticate  or  not.    the  researchers   reviewed  an  extensive  amount  of  data  to  identify  the  factors  involved  with  this  decision.   introduction   concerns  surrounding  usability,  administration,  and  privacy  with  user  authentication  on  public   computers  are  not  new  issues  for  librarians.  however,  in  recent  years  there  has  been  increasing   pressure  on  all  types  of  libraries  to  require  authentication  of  public  computers  for  a  variety  of   reasons.  since  the  9/11  tragedy,  there  has  been  increasing  legislation  such  as  the  uniting  and   strengthening  america  by  providing  appropriate  tools  required  to  intercept  and  obstruct   terrorism  act  of  2001  (usa  patriot  act)  and  communications  assistance  for  law  enforcement   act  (calea).    in  response,  administrators  and  campus  it  staff  have  become  increasingly   concerned  about  allowing  open  access  anywhere  on  their  campuses.    restrictive  licensing   agreements  for  specialized  software  and  web  resources  are  also  making  it  necessary  or  attractive   to  limit  access  to  particular  academic  subgroups  and  populations.    permitting  access  to  secured   campus  storage  from  these  computers  can  make  it  necessary  for  libraries  to  think  about  the   necessity  of  authentication.    and  finally,  the  general  state  of  the  economy  has  increased  the  user   traffic  to  libraries,  sometimes  making  it  necessary  to  control  the  use  of  limited  computer   resources.  authenticating  can  often  make  these  changes  easier  to  implement  and  can  give  the   library  more  control  over  its  it  environment.         that  being  said,  authentication  comes  at  a  price  for  librarians.  authentication  often  creates  ethical   issues  with  regards  to  patron  privacy,  freedom  of  inquiry,  increasing  the  complexity  of  using   public  area  machines,  and  restricting  the  open  access  needs  of  public  or  guest  users.    requiring  a   patron  to  log  into  a  computer  can  make  it

 consuming   and  frustrating  for  both  the  patron  and  the  library  staff.1  while  open,  anonymous  access  does  not   completely  protect  against  these  issues,  it  can  help  to  create  an  environment  of  free,  private  and   open  access  similar  to  the  longstanding  situation  with  the  book  collection  in  most  libraries.     the  hunter  library  experience   while  working  on  the  implementation  of  a  new  campus-­‐wide  pay-­‐for-­‐print  solution  in  2009,   librarians  from  the  hunter  library  at  western  carolina  university  began  to  feel  pressured  by  the   campus  it  department  to  change  its  practice  of  allowing  anonymous  logins  to  all  the  computers  in   the  public  areas  of  the  library.    concerns  about  authenticating  users  on  library  public  area   machines  had  been  building  between  these  two  units  for  several  years.    the  resulting  clash  of   principles  between  protecting  privacy  and  protecting  security  came  to  a  head  over  this  project.   the  hunter  library  employees  perceived  that  there  needed  to  be  more  time  for  research  and   debate  before  implementing  the  preceded  mandate.  initially,  there  was  great  resistance  from   campus  it  staff  to  take  the  library’s  concerns  into  account,  but  eventually  a  compromise  was   worked  out  that  allowed  the  library  to  retain  anonymous  logins  on  its  public  computers.    the   confrontation  led  library  staff  to  investigate  the  practices  of  other  libraries,  particularly  within  the   university  of  north  carolina  (unc)  system  of  which  it  is  a  member.    it  seemed  a  logical   development  to  extend  the  initial  research  into  the  authentication  practices  throughout  the  state   of  north  carolina.   the  problem   one  of  the  first  questions  asked  by  western  carolina’s  library  administration  of  the  systems   department  was  what  other  libraries  in  the  area  were  doing.    in  our  case,  the  library  director   specifically  asked  how  many  of  west  carolina’s  sister  universities  were  authenticating  and  why.   anecdotally,  during  this  process,  it  seemed  that  many  other  university  of  north  carolina  system   libraries  reported  being  pressured  to  authenticate  their  public  computers  by  organizations   outside  the  library,  most  often  the  campus  it  department.   when  the  librarians  at  the  hunter  library  began  looking  at  research  to  support  their  position,   hard  data  and  practical  arguments  that  could  be  used  to  effectively  argue  their  case  against  this   change,  helpful  literature  seemed  to  be  lacking.  some  items  were  found  such  as  carlson,  writing  in   the  chronicle  of  higher  education,  who  reported  on  the  divide  between  access  and  security.  he   confirmed  that  other  librarians  also  have  ambivalent  feelings  about  authentication  issues  but  that   there  was  also  growing  understanding  in  libraries  about  the  potential  vulnerability  of  networks  or   misuse  of  their  resources.2     it  seemed  that  the  speed  at  which  authenticating  computers  in  the  public  areas  of  libraries  was   happening  across  the  country  had  not  really  allowed  the  literature  on  the  subject  to  quite  catch  up.     information  technology  and  libraries  |  june  2015     105           those  studies  that  existed  such  as  spec  kits  seem  to  address  the  issue  from  the  perspective  of   larger  research  libraries  or  else  did  not  systematically  assess  other  specific  groups  of  libraries.3,4     there  were  questions  in  our  minds  about  whether  the  current  research  that  was  found  would   describe  the  trends  and  unique  situations  of  libraries  located  in  rural  areas  or  in  other  types  of   academic  libraries.  there  seemed  to  be  no  current  statewide  or  geographically  defined  analysis  of   authentication  practices  across  various  types  of  academic  libraries  in  a  specific  state  or  region,  nor   were  there  any  available  studies  creating  a  profile  of  libraries  more  likely  to  authenticate   computers  in  their  public  areas.  we  questioned  if  the  rural  nature  of  our  settings,  our  mission,  or   our  geographic  area  in  the  south  might  reinforce  or  hurt  our  position  with  it.    authentication   status  is  not  something  that  is  mentioned  in  the  ala  directory  nor  is  this  kind  of  information  often   given  on  a  library’s  web  site.    we  found  that  individuals  usually  need  to  call  or  visit  the  library   directly  if  they  want  to  know  about  a  library’s  authentication  practices.   during  the  initial  investigation,  the  need  for  this  kind  of  information  to  support  the  library’s   perspective  became  clear.    this  question  led  to  the  creation  of  this  survey  of  authentication   practices  in  a  larger  geographical  area  and  across  various  kinds  of  academic  libraries.    the  goals  of   this  research  were  to  determine  some  answers  to  the  following  questions:   • what  is  the  current  state  of  authentication  practices  in  the  public  area  of  academic  libraries   in  north  carolina?       • what  factors  caused  these  libraries  to  make  the  decisions  that  they  did  in  regards  to   authentication?   • could  you  predict  whether  an  academic  library  would  require  users  to  authenticate?   literature  review   a  number  of  studies  have  discussed  various  other  aspects  of  user  authentication  in  libraries,   including  privacy  and  academic  freedom  concerns,  guest  access  policies,  differing  views  of  privacy   and  access  between  library  and  campus  it  departments,  and  legislation  impacting  library   operations.  all  are  potential  factors  impacting  decisions  on  authentication  of  patron  accessible   computers  located  in  the  public  areas  of  library.   privacy  and  academic  freedom  about  the  use  of  a  library’s  collection  have  long  been  major   concerns  for  librarians  even  before  information  technology  was  introduced.  the  impact  of  9/11   and  the  patriot  act  made  the  discussion  of  computers  and  network  security,  especially  in  the   library  environment  much  more  entwined.    oblinger  discussed  online  access  concerns  in  the   context  of  academic  values,  focusing  on  unique  aspects  of  the  academic  mission.  she  discussed  the   results  of  an  educause/internet2  computer  and  network  security  task  force  invitational   workshop  that  established  a  common  set  of  principles  as  a  starting  point  for  discussion:  civility   and  community,  academic  and  intellectual  freedom,  privacy  and  confidentiality,  equity  of  access  to   resources,  fairness,  and  ethics.  all  of  these  principles,  she  argues,  are  integral  to  the  environment     user  authentication  in  the  public  library  area  of  academic  libraries  in  north  carolina  |     106   ellern,  hitch,  and  stoffan   doi:  10.6017/ital.v34i2.5770   of  a  university  and  concluded  that  security  is  a  complex  topic  and  that  written,  top-­‐imposed   policies  alone  will  not  adequately  address  all  concerns.5  while  not  directly  addressing  the  issues  of   the  library’s  public  computer  access  in  particular,  she  established  a  framework  of  values  on  how   security  issues  relate  to  the  university  culture  of  freedom  and  openness.   dixon  in  an  article  written  for  library  administrators  discussed  privacy  practices  for  libraries   within  the  context  of  the  library  profession’s  ethical  concerns.  she  highlights  such  documents  as   the  code  of  ethics  of  the  american  library  association6,  the  fair  information  practices  adopted  by   the  organization  for  economic  cooperation  and  development7,  and  the  niso  best  practices  for   designing  web  services  in  the  library  context8.    she  also  reviews  a  variety  of  ways  that  patron  data   may  be  misused  or  compromised.  she  stated  that  all  the  ways  that  patron  data  can  be  be  stored  or   tracked  by  local  networks,  it  departments,  or  internet  service  providers  may  not  be  fully   understood  by  librarians.  while  most  librarians  ardently  maintain  the  privacy  of  patron   circulation  records,  she  points  out  that  similar  usage  data  on  online  activities  may  be  collected   without  the  librarians  or  their  patrons  being  aware.  dixon  studied  the  current  literature  and   maintained  that  libraries  need  to  be  closely  involved  in  decisions  about  the  collection  and   retention  of  patron  usage  data,  especially  when  patron  authentication  and  access  is  controlled  by   external  agencies  such  as  campus  or  city  it  departments,  because  of  a  tendency  for  security  to   prevail  over  privacy  and  free  inquiry.9  this  theme  was  of  major  importance  to  us  in  preparing  the   present  study  as  it  shows  that  we  are  not  alone  in  these  concerns.   carter  focused  on  the  balance  between  security  and  privacy  and  suggested  several  possible   scenarios  for  addressing  both  areas.  he  emphasized  librarian  values  involving  privacy  and   intellectual  freedom,  contrasting  the  librarian’s  focus  on  unrestricted  access  with  the  over-­‐arching   security  concerns  of  computing  professionals.  he  discussed  several  computer  access  policies  in   use  at  various  institutions  and  possible  approaches.  these  options  include  computer   authentication  (with  associated  privacy  concerns),  open  access  stations  visually  monitored  from   staffed  desks,  or  routine  purging  of  user  logs  at  the  end  of  each  session.  he  also  suggested   librarians  lobby  state  legislatures  to  have  computer  usage  logs  included  in  laws  governing  the   confidentiality  of  library  records.10   still  and  kassabian  provided  a  good  summary  of  internet  access  issues  as  they  affected  academic   libraries  from  legal  and  ethical  perspectives.  they  suggested  that  librarians  focus  on  public   obligations,  free  speech  and  censorship,  and  potential  for  illegal  activities  occurring  on  library   workstations.  the  issues  highlighted  in  the  article  have  increased  in  the  15  years  since  the  article   was  written  but  it  remains  the  best  available  overview.11  the  arguments  put  forth  in  this  article   proved  relevant  for  us  in  understanding  the  multitude  of  viewpoints  regarding  authentication   even  before  9/11.     in  the  post-­‐9/11  era,  essex  discussed  the  usa-­‐patriot  act  and  its  implications  for  libraries  and   patron  privacy.  some  of  the  9/11  terrorists  were  reported  to  have  made  use  of  public  library   computers  in  the  days  before  the  attack.  this  has  led  to  heighted  concern  about  patron  privacy     information  technology  and  libraries  |  june  2015     107           among  librarians.  accurate  assessment  of  its  impact  is  difficult  due  to  restrictions  placed  on   libraries  in  even  disclosing  that  they  have  been  subjected  to  search.12  while  not  directly   addressing  authentication,  the  article  highlights  privacy  issues  surrounding  library  records  of  all   types.     one  of  the  arguments  in  not  requiring  authentication  in  the  public  area  is  the  use  by  unaffiliated   users  of  academic  libraries.    this  is  especially  true  in  rural  areas  where  an  academic  library  might   be  some  of  the  best-­‐funded,  comprehensive  and  accessible  resources  in  a  geographical  area.    even   in  urban  areas,  guest  access  by  unaffiliated  users  is  a  growing  issue  for  many  academic  libraries   because  of  limited  resources,  software  licensing  problems  and  public  access  to  campus   infrastructure.  while  most  institutions  have  traditionally  offered  basic  library  services  to   unaffiliated  patrons,  the  online  environment  has  raised  new  problems.  weber  and  lawrence   provided  one  of  the  best  studies  of  these  issues.    their  work  surveyed  association  of  research   libraries  (arl)  member  libraries  to  determine  the  extent  of  mandatory  logins  to  computer   workstations  and  document  how  online  access  was  provided  to  non-­‐affiliated  guest  users.  they   concentrated  their  study  questions  on  federal  and  canadian  depository  libraries  that  must   provide  some  type  of  access  to  online  government  information,  with  or  without  authentication.   less  than  half  of  respondents  reported  having  any  written  policies  governing  open  access  on   computers  or  guest  access  policies.  of  the  61  responding  libraries  to  the  survey,  32  required  that   affiliated  users  authenticate,  and  of  these  libraries  and  23  had  a  method  for  authenticating  guest   users.13  this  article,  which  was  published  just  as  this  study  was  testing  and  evaluating  the  survey   instrument,  proved  to  be  very  useful  as  we  worked  with  our  questions  in  qualtrics™      and  dealt   with  the  irb  requirements.     courtney  explored  a  half-­‐century  of  changes  in  access  policies  for  unaffiliated  library  users.   viewing  the  situation  from  somewhat  early  in  the  shift  from  print  to  electronic  resources,  she   foresaw  the  potential  for  significantly  reduced  access  to  library  resources  for  non-­‐affiliated   patrons.  these  barriers  would  be  created  by  access  policy  issues  with  computing  infrastructure   and  licensing  limitations  by  database  vendors.    this  is  especially  true  if  a  library’s  licenses  or   policies  did  not  specifically  address  use  by  unaffiliated  users.  she  concluded  that  decisions  about   guest  access  to  online  library  resources  should  be  made  by  librarians  and  not  be  handed  over  to   vendors  or  campus  computing  staff.14  our  study  began  as  a  result  of  this  very  issue,  i.e.,  an  outside   entity  (campus  it)  determining  how  access  to  library  resources  should  be  controlled,  without   input  by  librarians  or  library  staff.   courtney  also  surveyed  814  academic  libraries  to  assess  their  policies  for  access  by  unaffiliated   users.    she  focused  on  all  library  services  including  building  access,  reference  assistance,  and   borrowing  privileges  in  addition  to  online  access.  many  libraries  were  also  cancelling  print   subscriptions  in  favor  of  online  access  and  she  questioned  the  impact  this  might  have  on  use  by   unaffiliated  users.    while  suggesting  little  correlation  between  decisions  to  cancel  paper   subscriptions  and  requiring  authentication  of  computer  workstations,  she  concluded  that  reduced     user  authentication  in  the  public  library  area  of  academic  libraries  in  north  carolina  |     108   ellern,  hitch,  and  stoffan   doi:  10.6017/ital.v34i2.5770   access  by  unaffiliated  users  would  be  an  unintended  consequence  of  this  change.15  this  article   proved  valuable  to  us  in  framing  our  study,  as  it  gave  us  some  idea  of  what  we  might  expect  to  find   and  provided  some  concepts  to  use  when  we  formulated  our  survey.     best-­‐nichols  surveyed  public  use  policies  in  11  nc  tax-­‐supported  academic  libraries  and  asked   similar  questions  to  our  own.  this  study  was  dated  and  didn’t  address  computer  resources,  but   some  of  the  same  issues  were  addressed.16  public  use  and  authentication  policies  have  the   potential  to  impact  one  another  and  how  the  library  responds.       courtney  called  on  librarians  to  conduct  a  carefully  thought  out  discussion  of  user  authentication   because  of  the  implications  for  public  access  and  freedom  of  inquiry.  while  librarians  are   traditionally  passionate  at  protecting  patron  privacy  involving  print  resources,  many  are  unaware   of  related  concerns  involving  online  authentication.  she  advocated  for  more  education  and  open   debate  of  the  issues  because  of  the  potential  gravity  of  leaving  decision-­‐making  in  the  hands  of   database  vendors  or  campus  it  departments.  decisions  regarding  authentication  and  privacy   impact  library  services  and  access,  and  therefore  need  to  include  input  from  librarians.17  as  this   study  included  a  summary  of  the  reasons  for  authentication  as  provided  by  surveyed  libraries,  it   also  gave  us  another  reference  point  to  use  when  comparing  our  results  and  highlighted  the   intellectual  freedom  issues  that  were  often  missing  or  glossed  over  in  other  studies.   barsun  surveyed  the  web  sites  of  the  100  association  of  research  libraries  to  assess  services  to   unaffiliated  users  in  four  areas:  building  access,  circulation  policies,  interlibrary  loan  services,  and   access  to  online  databases.  61  member  libraries  responded  to  requests  for  data.  she  explored  the   question  of  whether  the  policies  governing  these  services  would  be  found  on  a  library’s  web  site.   she  perceived  a  possible  disparity  between  increasing  demand  for  services  generated  by  members   of  the  public  who  are  discovering  a  library’s  resources  via  online  searching  and  the  library’s  ability   or  willingness  to  serve  outside  users.  while  she  did  not  address  computer  authentication  issues   directly,  she  did  find  that  a  significant  percentage  of  academic  library  web  sites  were  ambiguous   about  stating  the  availability  of  non-­‐authenticated  access  to  databases  from  onsite  computers.18   this  ambiguity  could  possibly  be  related  to  vague  usage  agreements  with  database  vendors  that   do  not  clearly  state  whether  non-­‐affiliated  users  may  obtain  onsite  access  to  these  resources.  in   “secret  shopper”  visits  done  as  part  of  our  own  research,  we  saw  a  disparity  between  what  was   stated  on  a  library’s  web  site  and  the  reality  of  access  offered.     method   it  seemed  appropriate  to  start  this  project  with  a  regional  focus.      none  of  the  studies  available   looked  at  authentication  geographically.    because  colleges  and  universities  within  a  state  are  all   subjected  to  the  same  economic,  political  and  environmental  factors,  looking  at  the  libraries  might   help  provide  some  continuity  for  creating  a  relevant  profile  of  current  practices.    north  carolina   has  a  substantial  number  of  academic  libraries  (114)  with  a  wide  variety  of  demographics.     historically,  the  state  supports  a  strong  educational  system  with  one  of  the  first  public  university     information  technology  and  libraries  |  june  2015     109           systems.    together  with  the  17  universities  within  university  of  north  carolina  system,  the  state   has  59  public  community  colleges,  36  private  colleges  and  universities,  and  3  religious  institutions.   religious  colleges  are  identified  as  those  whose  primary  degree  is  in  divinity  or  theology.    (see   chart  1.)     chart  1.  survey  participation  by  type  of  academic  library.   work  had  been  started  to  identify  the  authentication  practices  of  other  unc  system  libraries,  so   the  researchers  expanded  the  data  to  include  the  other  academic  libraries  within  the  state.  to   create  a  list  of  the  library’s  pertinent  information  for  this  investigation,  the  researchers  used  the   american  library  directory19,  the  nc  state  library’s  online  directories  of  libraries20,  and  visited   each  library’s  web  page  to  create  a  database.  the  researchers  augmented  each  library’s  data  to   include  information  including  the  type  of  academic  library  (public,  private,  unc  system  and   religious),  current  contact  information  on  personnel  who  might  be  able  to  answer  questions  on   authentication  policies  and  practices  in  that  library,  current  number  of  books,  institutional   enrollment  figures,  and  the  name  and  population  of  the  city  or  town  in  which  the  library  was   located.  the  library’s  responses  to  the  survey  were  also  tracked  in  the  database  with  spss  and   excel  employed  in  evaluating  the  collected  data.   a  western  carolina  institution  review  board  (irb)  “request  for  review  of  human  subject   research”  was  submitted  and  approved  using  the  following  statement:  “we  want  to  know  the   authentication  situation  for  all  the  college  libraries  in  north  carolina.”    the  researchers  discovered   quickly  that  the  definition  of  “authentication”  would  have  to  be  explained  to  the  review  board  and   many  of  the  responding  librarians  that  filled  out  the  survey.  the  research  goal  was  further   simplified  with  the  explanation  of  authentication  as  “how  do  patrons  identify  themselves  to  get     user  authentication  in  the  public  library  area  of  academic  libraries  in  north  carolina  |     110   ellern,  hitch,  and  stoffan   doi:  10.6017/ital.v34i2.5770   access  to  a  computer  in  the  public  area  of  a  library”  because  many  librarians  might  not  realize  that   what  they  do  is  “authentication”.       during  the  approval  phase,  there  was  some  question  about  whether  the  researchers  needed   formal  approval  because  much  of  the  information  could  be  collected  by  just  visiting  the  libraries  in   person.    the  researchers  saw  no  risk  of  potentially  disclosing  confidential  data.  however,  it  was   decided  that  it  was  better  to  go  through  the  approval  process,  since  the  survey  asked  the  librarians   whether  they  were  being  required  to  authenticate  by  outside  entities.    there  might  also  be  a  need   to  do  some  follow-­‐up  calls  and  there  was  a  plan  to  do  site  visits  to  the  local  libraries  in  order  test   the  data  for  accuracy.     the  qualtrics™  online  survey  system  was  used  to  create  the  survey  and  collect  the  responses.     contact  information  from  the  database  was  uploaded  to  the  survey  system  with  the  irb  approved   introductory  letter  to  each  library  contact  person  along  with  a  link  to  the  survey.    the  introductory   letter  described  the  goals  of  the  project  and  included  an  invitation  to  participate  as  well  as  refusal   language  as  required  by  the  irb  request.  the  same  language  was  used  in  the  follow  up  emails  and   phone  calls.   the  initial  (16)  surveys  were  administered  to  the  unc  system  libraries  in  october  –  december   2010  as  a  test  of  the  delivery  and  collection  system  on  qualtrics™,  with  the  rest  of  the  libraries   being  sent  the  survey  mid-­‐december  2010.         in  the  spring  of  2011,  the  researchers  followed  initial  survey  with  a  second  letter  and  then  with   phone  calls  and  emails.  during  the  follow  up  calls,  some  librarians  chose  to  answer  the  survey   questions  with  the  researcher  filling  it  out  over  the  phone.    most  filled  out  the  survey  themselves.     the  final  surveys  were  completed  in  april  2011.    because  the  status  of  authentication  is  volatile,   this  survey  data  and  research  represents  a  snapshot  in  time  of  their  authentication  practices   between  october  2010  and  april  2011.  the  researchers  did  see  changes  happening  over  the   course  of  the  surveying  process  and  made  changes  to  any  data  collected  in  follow  up  contact  in   order  to  maintain  the  most  current  information  about  that  library  for  the  charts,  graphs  and   presentations  made  from  the  data.     in  fall  2011,  the  researchers  did  a  “secret  shopper”  type  expedition  to  the  nearest  academic   libraries  by  visiting  in  person  as  a  guest  user.    the  main  purpose  of  these  visits  was  to  check  the   data,  take  pictures  of  the  library  public  areas,  get  a  firsthand  experience  with  the  variety  of   authentication  practices,  and  talk  to  and  thank  the  librarians  that  participated.   the  survey   the  survey  asked  36  different  questions  using  a  variety  of  pull  down  lists,  check  boxes  and  fill  in   the  blank  questions.    qualtrics™  allows  for  the  survey  to  have  seven  branches,  or  skip  logic,  that   asked  further  questions  depending  upon  the  answer  given.    these  branches  allowed  the  survey   software  to  skip  particular  sections  or  ask  for  additional  information  depending  on  the  answers     information  technology  and  libraries  |  june  2015     111           supplied.    some  libraries,  especially  those  that  didn’t  authenticate  or  didn’t  know  specific  details,   might  be  asked  as  little  as  14  questions  while  others  received  all  36.  the  setup  of  computers  in  the   public  area  of  libraries  can  be  quite  variable,  especially  if  the  library  differentiates  between   student-­‐only  and  guest/public  use  only  workstations.  the  survey  questions  were  grouped  into   seven  basic  areas:  descriptive,  authentication,  student-­‐only  pcs,  guest/public  pcs,  wireless   access,  incident  reports,  and  computer  activity  logs.     the  full  survey  is  included  as  appendix  a.   initial  hypothesis   given  the  experience  at  the  hunter  library,  we  expected  the  following  factors  might  influence  a   decision  to  authenticate.    some  of  these  basic  assumptions  did  influence  our  selection  of  questions   in  the  seven  areas  of  the  survey.     we  expected  to  find:   • when  the  workstations  were  under  the  control  of  campus  it,  authentication  would  usually   be  required   • when  the  workstations  were  under  the  control  of  the  library,  authentication  would   probably  not  be  required   • that  factors  such  as  population,  enrollment,  and  book  volume  would  play  a  role  in   decisions  to  authenticate     • that  librarians  would  not  be  aware  of  what  user  information  was  being  logged  whether  or   not  authentication  was  required   • a  library  would  have  experienced  incidents  involving  the  computers  in  the  public  area  that   the  library  would  have  authentication     • that  authentication  increased  from  post-­‐  9/11  factors  and  its  legal  interpretations  to  force   libraries  to  authenticate   survey  questions,  responses,  and  general  findings     the  data  collected  from  this  survey,  especially  from  those  libraries  that  did  authenticate,  produced   over  200  data  points  for  each  library.  below  are  those  that  resulted  in  answers  to  questions  posed   at  the  outset  that  particularly  looked  at  overall  authentication  practices.  further  articles  are   planned  to  look  at  areas  of  inquiry  with  regards  to  other  related  practices  in  the  public  areas  of   academic  libraries  geographically.   there  are  114  academic  libraries  in  north  carolina.  as  a  result  of  the  follow  up  emails  and

 this  study,  they   were  very  cooperative  and  willing  to  fill  out  the  survey.    those  who  were  contacted  via  phone   mentioned  that  the  original  email  was  overlooked  or  lost.    only  one  library  refused  to  participate   in  the  study.     individual  library’s  demographics  were  collected  in  a  database  by  using  directory  and  online   information.    the  data  was  matched  with  the  survey  data  provided  by  the  respondents  to  produce   more  in-­‐depth  analysis  and  create  a  profile  of  each  library.           how  many  libraries  in  north  carolina  are  authenticating?  (chart  2)   the  survey  asked:  “is  any  type  of  authentication  required  or  mandated  for  using  any  of  the  pcs  in   the  library’s  public  area?”  66%  (or  75)  of  libraries  answered  yes  that  they  required  authentication   to  use  the  pcs.  (see  chart  2.)         chart  2.     are  some  types  of  libraries  more  likely  to  authenticate?  (chart  3)   while  each  type  of  library  had  a  different  overall  total  as  compared  to  the  other  types,  chart  3   shows  how  the  percentages  of  authentication  hold  for  each  type.    three  out  of  the  four  types  of   libraries  authenticate  more  often.    of  the  58  community  college  libraries,  60%  (or  35)  of  them   require  users  to  authenticate.    seventy-­‐eight  percent  (78%)  of  the  36  private  colleges  libraries   authenticate  and  11  of  the  16  (or  69%)  unc  system  libraries  authenticate.    only  the  religious   college  libraries  more  often  don’t  require  users  to  authenticate  (1  of  the  3  or  33%),  although  this   is  a  very  small  population  in  the  survey.    however,  percentagewise,  community  colleges  are  more   likely  to  not  require  users  to  authenticate  then  private  college  libraries  (40%  vs.  22%)  and  the   unc  system  libraries,  that  are  public  institutions,  fall  in  the  middle  at  31%.     information  technology  and  libraries  |  june  2015     113             chart  3.     how  many  academic  libraries  were  required  to

 authentication”,  59  (52%)  replied  “yes”.    putting  these  data  points  together  shows  that  16  (or   14%)  of  the  libraries  authenticate  even  though  they  were  not  required  to  do  so.      some  clues  about   why  this  was  were  asked  in  the  next  question  and  during  the  follow  up  phone  calls.         chart  4.       user  authentication  in  the  public  library

 know  the  reasons  why  authentication  is  being  used?”  if  they   answered  “prevent  misuse  of  resources”  or  “control  the  public’s  use  of  these  pcs”  then  an   additional  question  was  asked,  “what  led  the  library  to  control  the  use  of  pcs?”      this  option  had   two  check  boxes  (“inability  of  students  to  use  the  resources  due  to  overuse  by  the  public”  and   “computer  abuse”)  and  a  third  box  to  allow  free  text  entry.      a  library  could  check  more  than  one   box.   of  those  75  libraries  that  authenticated,  60%  (or  45)  checked  “prevent  misuse  of  resources”  and   48%  (or  36)  cited  “controlling  the  public’s  use  of  these  pcs”  as  the  reasons  for  authenticating.   in  normalizing  the  data  from  the  two  questions  and  the  free  text  field,  table  1  combines  all   answers  to  illustrate  the  number  and  percentages  of  each.     table  1.     in  the  course  of  the  follow  up  calls  with  those  libraries  that  answered  the  survey  over  the  phone,   further  insight  was  provided.  one  librarian  said  that  their  it  department  told  them   “authentication  was  the  law  and  they  had  to  do  it”.  another  answered  that  they  were  “on  the  bus   line  and  so  the  public  used  their  resources  more  than  they  expected  and  so  they  had  to”.   to  get  a  better  understanding  of  the  scope  and  variety  of  these  answers,  here  are  some  examples   of  the  reasons  cited  in  the  free  text  space:  “all  it's  idea  to  do  this”  “best  practices”,  “caution”,   “concerned  they  would  be  used  for  the  wrong  reasons”,  “control”,  “we  found  them  misusing   computer  resources  (porn,  including  child  porn)”,  “control  over  college  students  searching  of   inappropriate  websites,  such  as  porn/explicit  sites”,  “disruption”,  “ease  of  distributing     information  technology  and  libraries  |  june  2015     115           applications”,  “fear  of  abuse  on  the  part  of  legal”,  “legal  issues  regarding  internet  access”,  “making   students  accountable”,  “monitor  use”,  “policy”,  “security  of  campus  network”,  “security  of   machines  after  issues  were  raised  at  a  conference”,  and  “time”.   who  required  that  the  libraries  authenticate?  (chart  5)   the  survey  asked,  “what  organization  or  group  required  or  mandated  the  library  to  use   authentication?”    respondents  were  allowed  to  choose  more  than  one  of  the  5  boxes.    these   choices  included  “the  library  itself,”  “it  or  some  unit  within  it,”  “college  or  university   administration,”  “other”  (with  a  text  box  to  explain),  and  “not  sure”.    the  results  of  this  question   are  shown  in  chart  5.    the  survey  revealed  that  the  decision  was  solely  the  library’s  choice  25%  of   the  time,  (or  28  libraries)    22%  of  the  time  the  library  was  mandated  or  required  to  authenticate   by  it  or  some  unit  within  it  (or  25  libraries)  and  4%  of  the  time  a  library’s  college  or  university   administration  required  or  mandated  authentication  (or  4  libraries).      collaborative  decisions  in   14  libraries  involved  more  than  one  organization.    of  the  39  libraries  that  were  involved  with  the   authentication  decision  (28  that  made  the  decision  by  themselves  and  11  that  were  part  of  a   collaborative  decision),  55%  (or  16)  authenticated  even  though  they  were  not  required  to  do  it.     chart  5.   what  type  of  authentication  is  used?   authentication  in  libraries  can  take  many  forms.    the  most  common  method  for  those  libraries   that  authenticate  was  by  using  centralized  or  networked  systems.    almost  sixty  percent  of  the   libraries  used  some  form  of  this  identified  access  (tables  2  and  3)  with  one  library  using  some   other  independent  system.    twenty-­‐five  percent  (or  19)  of  libraries  that  authenticate  still  use   some  form  of  paper  sign-­‐in  sheets  and  21%  (or  16)  use  pre-­‐set  or  temporary  logins  or  guest  cards.     fifteen  percent  (or  11)  use  pc  based  sign-­‐in  or  scheduling  software  and  8%  (or  6)  use  the  library

 for  authentication.    a  few  libraries  indicated  that  they  bypass  their   authentication  systems  for  guests  by  either  having  staff  log  guests  in  or  disabling  the  system  on   selected  pcs.  we  saw  this  during  the  “secret  shopper”  visits  as  well.       table  2.   do  the  forms  of  authentication  used  in  libraries  allow  for  user  privacy?   when  asked  how  they  handle  user  privacy  in  authentication,  of  the  75  libraries  that  authenticate,   67%  (or  50)  use  a  form  of  authentication  that  can  identify  the  user.    in  other  words,  most  users  do   not  have  privacy  when  using  public  computers  in  an  academic  library  because  they  are  required  to   use  some  form  of  centralized  or  networked  authentication.  the  options  in  table  3  were  presented   to  the  respondents  as  possible  forms  of  privacy  methods.  thirty-­‐five  percent  (or  26)  libraries   indicated  that  they  provide  some  form  of  privacy  for  their  patrons.  anonymous  access  accounted   for  28%  (or  21)  of  the  libraries.       table  3.     information  technology  and  libraries  |  june  2015     117           are  librarians  aware  of  the  computer  logging  activity  going  on  in  the  public  area?  (table  4)   all  the  113  respondents  were  asked  two  questions  about  the  computer  logging  activities  of  their   libraries:  “do  you  know  what  computer  activity  logs  are  kept”  and  “do  you  know  how  long   computer  activity  logs  are  kept”.    the  second  question  was  only  asked  if  “unsure”  was  not  checked.   besides  “unsure”,  responses  on  the  survey  included  “authentication  logs  (who  logged  in)”,   “browsing  history  (kept  on  pc  after  reboot)”,  “browsing  history  (kept  in  centralized  log  files)”,   “scheduling  logs  (manual  or  software)”,  “software  use  logs”  and  “other”.  the  respondents  could   select  more  than  one  answer.  however,  over  half  (52%)  of  the  respondents  were  unsure  if  the   library  kept  any  computer  logs  at  all.  authentication  logs  of  who  logged  in  were  the  most  common,   but  those  were  kept  in  only  25%  of  the  total  libraries  surveyed.    a  high  percentage  of  libraries   kept  some  kind  of  logs  but  most  respondents  were  unsure  how  long  those  records  were  kept.    of   the  various  types  of  logs,  respondents  that  use  scheduling  software  were  the  most  familiar  with   the  length  of  time  software  logs  were  kept.  in  one  case,  a  respondent  mentioned  that  the  manual   sign-­‐in  sheets  were  never  thrown  out  and  that  they  had  retained  them  for  years.     table  4.  log

 their  public  areas?   of  the  75  libraries  that  authenticate,  only  one  implemented  this  more  than  ten  years  prior  to  the   survey.  51  (or  67%)  of  the  responding  libraries  began  authenticating  between  3  and  10  years  ago.     10  libraries  implemented  authentication  in  the  year  before  the  survey.    this  is  consistent  with  the   growth  of  security  concerns  in  the  post  9/11  decade.  (chart  7)     chart  7.     information  technology  and  libraries  |  june  2015     119           discussion   since  the  introduction  of  computer  technology  to  libraries,  library  staff  and  patrons  have  used   different  levels  of  authentication  depending  upon  the  application.    while  remote  access  to   commercial  services  such  as  oclc  cataloging  subsystems  or  vendor  databases  have  always  used   some  form  of  authorization,  usually  username  and  password,  it  has  never  been  necessary  or   desirable  for  public  access  to  the  library’s  catalog  system  to  have  any  kind  of  authorization   requirements.    most  of  the  collections  within  an  academic  library  have  traditionally  been  housed   in  open  access  stacks  where  anyone  can  freely  access  material  on  the  shelves.    printed  indexes  and   other  tools  that  provide  in-­‐depth  access  to  these  collections  have  traditionally  been  open  as  well.     today,  most  libraries  still  make  their  library  catalog  and  even  some  bibliographic  discovery  tools   open  access  and  available  over  the  web.  this  practice  naturally  extended  to  computer  technology   and  other  electronic  reference  tools  until  libraries  began  connecting  them  to  the  campus  and   public  networks.       the  principle  of  free  and  open  access  to  the  materials  and  resources  of  the  library,  within  the   library  walls,  has  been  a  fundamental  characteristic  of  most  public  and  academic  libraries.  there  is   an  ethical  commitment  of  librarians  to  a  user’s  privacy  and  confidentiality  that  has  deep  roots   based  in  the  first  and  fourth  amendment  of  the  us  constitution,  state  laws,  and  the  code  of  ethics   of  the  ala.    article  ii  of  the  ala  code  states  “we  protect  each  library  user's  right  to  privacy  and   confidentiality  with  respect  to  information  sought  or  received  and  resources  consulted,  borrowed,   acquired  or  transmitted.”  traditionally,  library  staff  do  not  identify  patrons  that  walk  through  the   door;  they  don’t  ask  for  identification  when  answering  questions  at  the  reference  desk  nor  do  they   identify  patrons  reading  a  book  or  magazine  in  the  public  areas  of  a  library.  schneider  has   empathized  that  librarians  have  always  valued  user  privacy  and  have  been  instrumental  in  the   passing  of  many  state’s  library  privacy  laws.23    usually,  it  is  only  when  materials  are  checked  out   to  a  patron  that  a  user’s  affiliation  or  authorization  even  gets  questioned  directly.  frequently   patrons  can  make  use  of  materials  within  the  library  building  with  no  record  of  what  was  accessed.   we  are  seeing  these  traditional  principles  of  open  access  to  materials  as  they  transition  to   electronic  formats.  it  is  becoming  more  common  for  patrons  to  have  to  authenticate  before  they   can  use  what  was  once  openly  available.  the  data  collected  from  this  survey  confirms  this  trend   with  66%  of  the  libraries  using  some  form  of  authentication  in  their  public  area.   the  widespread  use  of  personally  identifiable  information  is  making  it  more  difficult  for  librarians   to  protect  the  privacy  and  confidentiality  of  library  users.  although  the  writing  was  on  the  wall   that  some  choices  would  have  to  be  made  with  regards  to  privacy  before  911,  no  easy  answer  to   the  problem  had  yet  been  identified.  librarians  themselves  are  often  uncertain  about  what   information  is  collected  and  stored  as  evidenced  by  our  data  (chart  6).    as  more  information   becomes  available  only  electronically,  because  computers  in  the  public  areas  are  now  used  for   much  more  than  just  accessing  library  catalog  functions,  it  is  becoming  difficult  to  uphold  the  code   of  ethics  and  protect  the  privacy  of  users.       user  authentication  in  the  public  library  area  of  academic  libraries  in  north  carolina  |     120   ellern,  hitch,  and  stoffan   doi:  10.6017/ital.v34i2.5770   using  authentication  can  also  make  it  more  difficult  to  use  technology  in  the  library.    in  order  to   authenticate,  users  may  be  required  to  start  or  restart  a  computer  and/or,  log  into  or  out  of  the   computer.    this  can  take  time  to  do  as  well  as  require  the  user  to  remember  to  log  off  the   computer  when  finished.  users  often  have  difficulty  keeping  track  of  their  user  information  and   may  require  increased  assistance  (table  5).     table  5.   library  staff  or  scheduling  software  can  be  required  to  help  library  guests  obtain  access  to   computer  equipment.    north  carolina,  like  other  states,  does  have  laws  governing  the   confidentiality  of  library  records.  librarians  have  long  dealt  with  this  situation  by  keeping  as  little   data  as  possible.  for  example,  many  library  circulation  systems  do  not  store  data  beyond  the   current  checkout.  access  logs  that  detail  what  resources  a  particular  user  has  accessed  would   seem  to  fall  under  this  legislation,  although  the  wording  in  the  law  is  vague.   information  technology  departments,  legal  counsel,  and  administrators,  on  the  other  hand,  are   often  less  concerned  about  privacy  and  intellectual  freedom  issues.  more  often  their  focus  is  on   security,  limiting  access  to  those  users  affiliated  with  the  institution,  and  monitoring  use.  being   ready  and  able  to  provide  data  in  response  to  subpoenas  and  court  orders  is  often  a  priority.  at   western  carolina  university,  illicit  use  of  an  unauthenticated  computer  in  the  student  center  led  to   an  investigation  by  campus  and  county  law  enforcement.  this  case  is  still  used  as  justification  for   needing  to  authenticate  and  monitor  campus  computer  use  even  though  the  incident  occurred   many  years  ago.  being  able  to  track  an  individual’s  online  activity  is  believed  to  increase  security   by  ensuring  adherence  to  institutional  policies.  authentication  with  individually  assigned  login   credentials  permits  online  activity  to  be  traced  to  that  specific  account  whose  owner  can  then  be   held  accountable  for  the  activity  performed.  librarian’s  responses  to  the  survey  indicate  that  these   issues  play  a  role  in  a  library’s  decisions  to  authenticate  as  seen  in  the  free  text  responses  in  table   6.     information  technology  and  libraries  |  june  2015     121           tracking  use  through  ip  address,  individual  login,  and  transaction  logs  allows  scrutinizing  of  users   in  case  of  illegal  or  illicit  use  of  computer  resources.  in  many  cases,  this  action  is  justified  as  being   required  by  auditors  or  law  enforcement  agencies,  though  information  regarding  this  is  scarce.   the  authors  of  this  article  are  not  aware  of  any  laws  or  auditing  requirements  in  north  carolina   that  require  detailed  tracking  of  library  computer  use.     some  libraries  indicated  that  it  departments  were  concerned  about  security  of  networks  and/or   computers.  security  can  be  undermined  when  generic  accounts  are  used  or  when  no   authentication  is  required.  by  using  individual  logins,  users  can  be  restricted  to  specific  network   resources  and  can  be  monitored.  when  multiple  computers  use  the  same  account  for  logging  in  or   when  the  login  credentials  are  posted  on  each  computer,  it  can  compromise  security  because  use   cannot  be  tracked  to  a  specific  user.  in  some  libraries,  these  security  issues  have  trumped   librarian’s  concerns  about  intellectual  freedom  and  privacy.   creating  a  profile  as  a  result  of  these  findings   given  the  number  of  characteristics  collected  about  each  library,  it  was  assumed  there  were  some   factors  gathered  that  might  influence  a  decision  to  authenticate  and  allow  for  the  possibility  to   create  a  profile  for  prediction.  the  data  was  collected  from  libraries  within  a  fixed  geographic   region.  the  externally  collected  and  survey  data  was  coded,  put  into  spss™  and  a  number  of   statistical  tests  were  performed  to  find  what  factors  might  be  statistically  significant.    to  further   the  geographical  analysis  of  the  data,  the  data  was  also  put  into  arcview™  to  produce  a  map  of   north  carolina  with  the  libraries  given  different  colored  pins  for  those  academic  libraries  that   authenticated  vs.  non-­‐authenticated  to  see  if  there  were  any  pattern  to  the  choice.  (map  1)     to  more  completely  explore  the  possible  role  that  geographic  information  might  play  in  the   decision  to  authenticate,  the  population  of  the  city  or  town  the  institution  was  located  in,   enrollment,  book  volume,  number  of  pcs  and  total  number  of  library  it  staff  (scaled  variables)  as   well  as  ordinal  variables  such  as  “who  controlled  the  setup  of  the  pcs”,  “do  you  differentiate   between  student  and  public  pcs”,  and  “known  incidents  of  privacy  and  misuse”,  were  also   integrated  into  the  analysis.    the  data  collected  could  not  predict  whether  an  academic  library   would  authenticate  or  not  using  logistical  regression  techniques,  although  those  that  differentiate   between  student  and  public  pcs  did  have  a  higher  probability.    based  on  all  our  collected  data  and   mapping,  it  is  impossible  to  predict  with  any  significance  whether  or  not  an  academic  library   would  authenticate.     so  the  short  answer  statistically  is  no.    using  all  of  the  data  collected,  a  statistically  significant   profile  could  not  be  created,  however  there  are  general  tendencies  identified  that  the  data  was   able  to  suggest.       user  authentication  in  the  public  library  area  of  academic  libraries  in  north  carolina  |     122   ellern,  hitch,  and  stoffan   doi:  10.6017/ital.v34i2.5770     map  1.   for  those  libraries  that  do  authenticate,  the  average  book  volume  is  almost  400,000,  the   enrollment  around  5,600,  the  city  population  where  the  institution  is  located  is  94,000,  the  total   number  of  pcs  in  the  public  area  is  54,  and  the  average  number  of  library  it  staff  is  1.8.         for  those  libraries  that  do  not  authenticate,  the  average  book  volume  is  about  163,000,  enrollment   around  3,000,  the  population  is  53,000,  the  average  number  of  pcs  in  the  public  area  is  about  39   and  the  average  number  of  library  it  staff  is  0.8.     libraries  that  authenticate  tend  to  have  statistically  significant  differences  in  book  volume,  the   number  of  pcs  in  the  public  area,  which  has  a  t-­‐test  value  of  p<1.    student  enrollment  was  the  most   statistically  significant  factor  in  those  that  authenticated,  with  a  t-­‐test  value  of  p<0.5.  libraries  that   authenticate  had  many  more  students,  more  books  and  a  larger  number  of  pcs  in  their  public   areas  then  libraries  that  didn’t  authenticate.   those  libraries  that  didn’t  authenticate  tended  to  be  in  smaller  towns,  more  often  their  pcs  in  the   public  areas  were  setup  by  non-­‐library  it  staff,  and  had  fewer  library  it  staff.  sixty  percent  (60%)   of  the  libraries  that  don’t  authenticate  had  zero  library  it  staff.           information  technology  and  libraries  |  june  2015     123           while  it  was  assumed  at  the  outset  of  this  research  that  the  responsible  campus  department  for   the  setup  of  the  workstations  (the  library  or  it)  in  the  public  area  would  be  a  factor  in  whether   authentication  was  used  in  the  library,  the  data  does  not  support  this  assumption  statistically.   ethical  questions  about  authentication  as  a  result  of  these  findings   there  are  a  variety  of  reasons  why  a  library  might  choose  to  authenticate  despite  the  ethical  issues   associated  with  it.  the  protection  and  management  of  it  resources  or  the  mission  of  the   institution  are  two  likely  scenarios.    a  library,  especially  one  with  lots  of  use  by  unaffiliated  users   or  guests,  might  chose  to  authenticate  regardless  of  concerns  in  order  to  make  sure  its  own  users   have  preference  to  the  pcs  in  the  public  area  of  their  library.  a  private  institution  may  choose  to   authenticate  in  order  to  limit  access  by  any  members  of  the  general  public.  of  those  75  libraries   that  authenticate,  81%  cited  concerns  about  controlling  use,  overuse  and  misuse.  this  study  also   found  that  in  25%  of  the  total  academic  libraries,  the  library  itself  decided  to  authenticate  without   influence  from  external  groups.  this  was  a  higher  percentage  than  was  expected.  given  librarian’s   professional  concerns  about  intellectual  freedom  and  privacy,  we  were  very  surprised  that  so   many  libraries  choose  to  authenticate  on  their  own.   we  suspected  that  many  librarians  might  not  have  a  full  understanding  of  the  privacy  issues   created  when  requiring  individual  logins.    based  on  this  assumption,  we  expected  that  many  of  the   librarians  would  not  be  fully  aware  of  what  user  tracking  data  was  being  kept.    examples  include   network  authentication,  tracking  cookies,  web  browser  history,  and  user  sign-­‐in  sheets.  the  study   found  that  librarians  are  often  unsure  of  what  data  is  being  logged  with  51  (or  45%)  of  113   libraries  reporting  this.    only  19%  reported  knowing  with  certainly  that  no  tracking  data  was  kept.     of  those  that  did  know  that  tracking  data  was  being  kept,  most  had  no  idea  how  long  this  data  was   retained.   conclusion   this  study  found  that  66%  (or  75)  of  the  113  surveyed  north  carolina  academic  libraries  required   some  form  of  user  authentication  on  their  public  computers.  the  researchers  reviewed  an   extensive  amount  of  data  to  identify  the  factors  involved  with  this  decision.    these  factors   included  individual  demographics,  such  as  city  population,  book  volume,  type  of  academic  library,   and  enrollment.    it  was  anticipated  that  by  looking  a  large  pool  of  academic  libraries  within  a   specific  region,  a  profile  might  emerge  that  would  predict  which  libraries  would  chose  to   authenticate.    even  with  comprehensive  data  about  the  75  libraries  that  authenticated,  a  profile  of   a  “typical”  authenticated  library  could  not  be  developed.    the  data  did  show  two  factors  of  any   statistical  significance  (enrollment  and  book  volume)  in  determining  a  library’s  decision  to   authenticate.    however,  the  decision  to  authenticate  could  not  be  predicted.    each  library’s   decision  to  authenticate  seems  to  be  based  on  the  unique  situation  of  that  library.     we  expected  to  find  that  most  libraries  would  authenticate  due  to  pressure  from  external  sources,   such  as  campus  it  departments,  administrators,  or  in  response  to  incidents  involving  the     user  authentication  in  the  public  library  area  of  academic  libraries  in  north  carolina  |     124   ellern,  hitch,  and  stoffan   doi:  10.6017/ital.v34i2.5770   computers  in  the  public  area.  this  study  found  that  only  39%  (or  44)  libraries  surveyed   authenticated  due  to  these  factors  so  our  assumption  was  incorrect.      surprisingly,  we  found  that   25%  (or  28)  libraries  did  choose  to  authenticate  on  their  own.  the  need  to  control  the  use  of  their   limited  resources  seemed  to  have  precedence  over  any  other  factors  including  user  privacy.  we   did  expect  to  see  a  rise  in  the  number  of  libraries  that  authenticated  in  the  aftermath  of  9/11.  this   we  found  to  be  true.  looking  at  the  prior  research  that  define  an  actual  percentage  of   authentications  in  academic  libraries,  no  matter  how  limited  in  scope,  (for  example,  just  the  arl   libraries,  responding  libraries,  etc.),  there  does  seem  to  be  a  strong  trend  for  academic  libraries  to   authenticate.   our  results,  with  75%  of  academic  libraries  having  authentication,  support  the  conclusion  that   there  is  a  continued  trend  of  authentication  that  has  steadily  expanded  over  the  past  decade.  this   has  happened  in  spite  of  librarian’s  traditional  philosophy  on  access  and  academic  freedom.   libraries  are  seemingly  relinquishing  their  ethical  stance  or  have  other  priorities  that  make   authentication  an  attractive  solution  to  controlling  use  of  limited  or  licensed  resources.    our   survey  results  show  that  many  librarians  may  not  fully  understand  the  privacy  risks  inherent  in   authentication.    slightly  over  half  (52%)  of  the  libraries  reported  that  they  did  not  know  if  any   computer  or  network  log  files  were  being  kept  nor  for  how  long  they  are  kept.   the  issues  surrounding  academic  freedom,  access  to  information,  and  privacy  in  the  face  of   security  concerns  continue  to  effect  library  users.  academic  libraries  in  smaller  communities  are   often  the  only  nearby  source  of  scholarly  materials.  traditionally  these  resources  have  been  made   available  to  community  members,  high  school  students,  and  others  who  require  materials  beyond   the  scope  of  the  resources  of  the  public  or  school  library.  as  pointed  out,  restrictive  authentication   policies  may  hamper  the  ability  of  these  groups  to  access  the  information  they  need.  however,  the   data  showed  very  little  consistency  to  support  this  idea  with  respect  to  authentication  in  small   towns  and  communities  throughout  the  state.   some  of  the  surveyed  academic  libraries  made  a  strong  statement  that  they  are  not  authenticating   in  their  public  area  computers  and  have  every  intention  of  continuing  this  practice.  these  libraries   are  now  in  a  distinct  minority  and  we  expect  their  position  will  continually  be  challenged.    for   example,  at  western  carolina  university,  we  continue  to  employ  open  computers  in  the  public   areas  of  the  library  but  are  regularly  pressed  by  our  campus  it  department  to  implement   authentication.  we  have  so  far  been  successful  in  resisting  this  pressure  because  of  the   commitment  of  our  dean  and  librarians  to  preserving  the  privacy  of  our  patrons.   further  studies   as  a  follow-­‐up  to  this  study,  we  plan  to  contact  the  35  libraries  that  did  not  authenticate  to   determine  if  they  now  require  authentication  or  have  plans  to  do  so.  based  on  responses  to  this   survey,  we  expect  that  many  librarians  are  unaware  of  the  degree  to  which  authentication  can   undermine  patron  privacy.  we  suggest  an  in-­‐depth  study  be  conducted  to  determine  the  degree  of

 jobs.code4lib.org.      monica  maceli     information  technology  and  libraries  |  september  2015             8   abstract   technology  plays  an  indisputably  vital  role  in  library  and  information  science  (lis)  work;  this  rapidly   moving  landscape  can  create  challenges  for  practitioners  and  educators  seeking  to  keep  pace  with   such  change.  in  pursuit  of  building  our  understanding  of  currently  sought  technology  competencies   in  developer-­‐oriented  positions  within  lis,  this  paper  reports  the  results  of  a  text  analysis  of  a  large   collection  of  job  listings  culled  from  the  code4lib  jobs  website.  beginning  more  than  a  decade  ago  as   a  popular  mailing  list  covering  the  intersection  of  technology  and  library  work,  the  code4lib   organization's  current  offerings  include  a  website  that  collects  and  organizes  lis-­‐related  technology   job  listings.  the  results  of  the  text  analysis  of  this  dataset  suggest  the  currently  vital  technology  skills   and  concepts  that  existing  and  aspiring  practitioners  may  target  in  their  continuing  education  as   developers.     introduction for  those  seeking  employment  in  a  technology-­‐intensive  position  within  library  and  information   science  (lis),  the  number  and  variation  of  technology  skills  required  can  be  daunting.  the  need  to   understand  common  technology  job  requirements  is  relevant  to  current  students  positioning   themselves  to  begin  a  career  within  lis,  those  currently  in  the  field  that  wish  to  enhance  their   technology  skills,  and  lis  educators.  the  aim  of  this  short  paper  is  to  highlight  the  skills  and   combinations  of  skills  currently  sought  by  lis  employers  in  north  america  through  textual   analysis  of  job  listings.  previous  research  in  this  area  explored  job  listings  through  various   perspectives,  from  categorizing  titles  to  interviewing  employers;1,2  the  approach  taken  in  this   study  contributes  a  new  perspective  to  this  ongoing  and  highly  necessary  work.  this  research   report  seeks  a  further  understanding  of  the  following  research  questions:   • what  are  the  most  common  job  titles  and  skills  sought  in  technology-­‐focused  lis  positions?   • what  technology  skills  are  sought  in  combination?   • what  implications  do  these  findings  have  for  aspiring  and  current  lis  practitioners   interested  in  developer  positions?     as  detailed  in  the  following  research  method  section,  this  study  addresses  these  questions     monica  maceli  (mmaceli@pratt.edu)  is  assistant

through  textual  analysis  of  relevant  job  listings  from  a  novel  dataset—the  job  listings  from  the   code4lib  jobs  website  (http://jobs.code4lib.org/).  code4lib  began  more  than  a  decade  ago  as  an   electronic  discussion  list  for  topics  around  the  intersection  of  libraries  and  technology.3  over  time,   the  code4lib  organization  expanded  to  an  annual  conference  in  the  united  states,  the  code4lib   journal,  and  most  relevant  to  this  work,  an  associated  jobs  website  that  highlights  jobs  culled  from   both  the  discussion  list  and  other  job-­‐related  sources.  figure  1  illustrates  the  home  page  of  the   code4lib  jobs  website;  the  page  presents  job  listings  and  associated  tags,  with  the  tags  facilitating   navigation  and  viewing  of  other  related  positions.  users  may  also  view  positions  geographically  or   by  employer.           figure  1.  homepage  of  the  code4lib  jobs  website,  displaying  most-­‐recently  posted  jobs  and  the   associated  tags.4   in  addition  to  the  visible  user  interface  for  job  exploration,  the  website  consists  of  software  to   gather  the  job  listings  from  a  variety  of  sources.  the  website  incorporates  jobs  posted  to  the   code4lib  discussion  list,  american  library  association,  canadian  library  association,  australian   library  and  information  association,  highered  jobs,  digital  koans,  idealist,  and  archivesgig.  this   broad  incoming  set  of  jobs  provides  a  wide  look  into  new  technology-­‐related  postings.     new  job  listings  are  automatically  added  to  a  queue  to  be  assessed  and  tagged  by  human  curators   before  posting.  this  allows  manual  intervention  where  a  curator  assesses  whether  the  job  is   relevant  to  technology  in  the  library  domain  and  to  validate  the  job  listing  information  and   metadata  (see  figure  2).  curating  is  done  on  a  volunteer  basis,  and  curators  are  asked  to  assess   whether  the  position  is  relevant  to  the  code4lib  community,  if  it  is  unique,  and  to  ensure  that  it   has  an  associated  employer,  set  of  tags,  and  descriptive  text.  combining  both  software  processes     information  technology  and  libraries  |  september  2015                   10   and  human  intervention  in  the  job  assessment  results  in  the  ability  to  gather  a  large  number  of   jobs  of  high  relevance  to  the  code4lib  community.  as  mentioned  earlier,  code4lib’s  origins  are  in   the  area  of  software  development  and  design  as  applied  in  lis  contexts.  these  foci  mean  that  most   jobs  identified  as  relevant  for  inclusion  in  the  code4lib  jobs  dataset  are  oriented  toward  developer   activities.  the  code4lib  jobs  website  therefore  provides  a  useful  and  novel  dataset  within  which  to   understand  current  employment  opportunities  relating  to  the  intersection  between  technology— particularly  developer  work—and  the  lis  field.       figure  2.  code4lib  job  curators  interface  where  job  data  is  validated  and  tags  assigned.5   research  method   to  analyze  the  job  listing  data  in  greater  depth,  a  textual  analysis  was  conducted  using  the  r   statistical  package,  exploring  job  titles  and  descriptions.6  first,  the  job  listing  data  from  the  most   recent  complete  year  (2014)  were  dumped  from  the  database  backend  of  the  code4lib  jobs   website;  this  dataset  contained  1,135  positions  in  total.  the  dataset  included  the  job  titles,   descriptions,  location  and  employer  information,  as  well  as  tags  associated  with  the  various     what  technology  skills  do  developers  need?  |  maceli   doi:  10.6017/ital.v34i3.5893   11   positions.  the  text  was  then  cleaned  to  remove  any  markup  tags  or  special  characters  that   remained  from  the  scraping  of  listings.  finally,  the  tm  (text  mining)  package  in  r  was  used  to   calculate  frequency,  correlation  of  terms,  generate  plots,  and  cluster  terms  across  both  job  titles   and  descriptions.7   results   job  title  analysis   of  the  full  set  of  1,135  positions,  30  percent  were  titled

 hierarchical   method  (dendogram  in  figure  5).  agglomerative  hierarchical  clustering,  of  which  ward’s  method   is  widely  used,  begins  first  with  single-­‐item  clusters,  then  identifies  and  joins  similar  clusters  until   the  final  stage  in  which  one  larger  cluster  is  formed.  commonly  used  in  text  analysis,  this  allows   the  investigator  to  explore  datasets  in  which  the  number  of  clusters  is  not  known  before  the   analysis.  the  dendograms  generated  (e.g.,  figure  5)  allow  for  visual  identification  and   interpretation  of  closely  related  terms  representing  various  common  positions,  e.g.,  digital   librarian,  software  engineer,  collections  management,  etc.  given  that  job  titles  in  listings  may   include  extraneous  or  infrequent  words,  such  as  the  organization  name,  the  cluster  analysis  can   provide  an  additional  view  into  common  job  titles  across  the  full  dataset  in  a  more  generalized   fashion.     182 141 116 90 86 68 65 59 59 59 55 52 49 49 40 40 40 40 38 35 34 34 33 32 24 digital developer library manager specialist software web archivist services

 interest  to  the  code4lib  community.  as  detailed  in  the  title  analysis   (figures  3  and  4),  apart  from  the  generic  term  librarian,  the  two  most  common  terms  across  all  job   titles  were  digital  and  developer.  correlation  plots  were  created  to  detail  the  specific  skills  and   requirements  commonly  sought  in  positions  using  such  terms.  figure  11  illustrates  the  terms   correlated  with  the  general  term  of  developer,  while  figure  12  displays  terms  correlated  with   digital.  the  implications  of  these  findings  will  be

19   discussion   taken  as  a  whole,  the  job  listing  dataset  covered  a  quite  dramatic  range  of  positions,  from  highly   technical  (e.g.,  senior-­‐level  software  engineer  or  web  developer)  to  managerial  and  leadership   roles  (e.g.,  director  or  department  head  roles  centered  on  digital  services  or  emerging   technologies).  these  findings  support  the  suggestions  of  earlier  research,8  which  advocated  for  lis   graduate  programs  to  build  their  offerings  not  just  in  technology  skills  but  also  in  technology   management  and  decision-­‐making.  however,  the  code4lib  jobs  dataset  is  a  one-­‐dimensional  view   into  the  employment  process  and  is  focused  largely  on  the  developer  perspective.  additional   contextual  information,  including  whether  suitable  candidates  were  easily  identified  and  if  the   position  was  successfully  filled,  would  provide  a  more  complete  view  of  the  employment  process.   prior  research  has  indicated  that  many  technology-­‐related  positions  in  lis  are  in  fact  difficult  to   fill  with  lis  graduates.9  while  lis  graduate  programs  have  made  great  strides  in  increasing  the   number  of  courses  and  topics  covered  that  address  technology,  these  improvements  may  not   benefit  those  already  in  the  field  or  wishing  to  shift  towards  a  more  technology-­‐focused  position.   in  the  common  tags  and  terms  analysis,  experience  with  specific  lis  applications  was  relatively   infrequently  required,  with  the  drupal  content  management  system  a  notable  exception.  more   generalizable  programming  languages  or  concepts,  e.g.,  python,  relational  databases,  xml,  etc.,   were  favored  as  with  technology  positions  outside  of  the  lis  domain,  employers  likely  seek  those   with  the  ability  to  flexibly  apply  their  skills  across  various  tools  and  platforms.  this  may  also   relate  to  the  above  challenges  in  filling  such  positions  with  lis  graduates,  with  the  goal  of  opening   up  the  position  to  a  larger  technologist  applicant  base.   common  web  technologies  popular  in  the  open-­‐source  software  often  favored  by  lis   organizations  continued  to  dominate,  with  a  clear  preference  for  candidates  well  versed  in  html,   css,  javascript,  and  php.  relating  to  these  skills,  web  development  and  design  practices  were   often  intertwined  with  positions  requesting  both  developer-­‐oriented  skillsets  as  well  as  interface   design  (e.g.,  figure  7).  technologies  supporting  modern  web  application  development  and   workflow  management  were  evident  as  well,  e.g.,  common  requirements  for  experience  with   versioning  systems  such  as  git,  popular  javascript  libraries,  and  development  frameworks.  also   striking  was  the  richness  of  the  terms  correlated  with  metadata  (figure  10),  including  mention  of   growing  areas  of  expertise,  such  as  linked  data.     interestingly,  the  general  correlation  plots  expressing  the  common  terms  sought  around  “digital”   and  “developer”  positions  were  quite  varied.  while  the  developer  plot  (figure  11  above)  provided   a  richly  technical  view  into  common  technologies  broadly  applied  in  web  and  software   development,  the  terms  correlated  around  digital  were  notably  less  technical  (figure  12  above).   while  there  was  a  clear  focus  on  digital  preservation  activities  and  common  standards  in  this  area,   mention  of  terms  such  as  “grant”  indicated  that  these  positions  likely  have  a  broad  role.  the  term   digital  was  frequently  observed  in  librarian  job  titles,  so  these  roles  may  be  tasked  with  both   technical  and  administrative  work.       information  technology  and  libraries  |  september  2015                   20   finally,  there  are  inherent  difficulties  in  capturing  all  jobs  relating  to  technology  use  in  the  lis   domain  that  introduce  limitations  into  this  study.  while  the  incoming  job  feeds  attempt  to  broadly   capture  recent  job  posts,  it  is  possible  that  jobs  are  missed  or  overlooked  by  the  job  curators.   given  the  lack  of  one  centralized  job-­‐posting  source  regardless  of  the  field,  this  is  a  common   challenge  to  research  work  attempting  to  assess  every  job  posting.  and  as  mentioned  above,  there   is  also  a  lack  of  corresponding  data  as  to  whether  these  jobs  are  successfully  filled  and  what   candidate  backgrounds  are  ultimately  chosen  (i.e.,  from  within  or  outside  of  lis).     conclusion   this  assessment  of  the  in-­‐demand  technology  skills  provides  students,  educators,  and  information   professionals  with  useful  direction  in  pursuing  technology  education  or  strengthening  their   existing  skills.  there  are  myriad  technology  skills,  tools,  and  concepts  in  today’s  information   environments.  reorienting  the  pursuit  of  knowledge  in  this  area  around  current  employer   requirements  can  be  useful  in  professional  development,  new  course  creation,  and  course  revision.   the  constellations  of  correlated  skills  presented  above  (figures  8–12)  and  popular  job  tags  (figure   7)  describe  key  areas  of  technology  competencies  in  the  diverse  areas  of  expertise  presently   needed,  from  web  design  and  development  to  metadata  and  digital  collection  management.  in   addition  to  the  results  presented  in  this  paper,  the  code4lib  job  website  provides  a  continuously   current  view  into  recent  jobs  and  related  tags;  this  data  can  help  those  in  the  lis  field  orient   professional  and  curricular  development  toward  real  employer  needs.   acknowledgements   the  author  would  like  to  thank  ed  summers  of  the  maryland  institute  for  technology  in  the   humanities  for  generously

static and stale to dynamic and collaborative: the drupal difference editor’s note: this paper is adapted from a presentation given at the 2010 lita forum. i n 2009, the university library of the university of california, santa cruz, moved from a static, dreamweaverand html-created website to an entirely new databasedriven website using the open-source content management system (cms) drupal. this article will describe the interdisciplinary approach the project team took for this large-scale transition process, with a focus on user testing, information architecture planning, user analytics, data gathering, and change management. we examine new approaches implemented for group-authoring of resources and the challenges presented by collaboration and crowdsourcing in an academic environment. we also discuss the impact on librarians and staff changing to this new paradigm of website design and development and the training support provided. we present our process for testing, staging, and publishing new content and describe the modules used to build dynamic subjectand course-guide displays. finally, we provide a list of resources and modules for beginning and intermediate drupal users. why change was needed our old library website was created using static html and its organizational structure evolved to mirror the administrative structure of the library. the vocabulary we used was very library-centric and, though useful to library staff, could be confusing to patrons. like many larger, older websites, we had accumulated a number of redundant and defunct pages. many of these pages had not been updated for years, had inconsistent naming conventions, or outdated page design. the catalyst for updating our web presence was predicated on several things. with more than one million visits per year and more than two million page views, our old servers were no longer able to handle this load, and we were about to begin a major project to replace our server hardware. in addition, we anticipated participating in an upcoming transition to a new campuswide website template. we saw this moment of change as an opportunity to revitalize the library website’s entire structure and reorganize it with a more user-centric approach to the menus and vocabulary. to do this, we decided to move away from dreamweaver and the static html approach to web design and instead choose a cms that would provide a more flexible and innovative interface. choosing drupal we had done research on commercial and open-source solutions and were leaning toward drupal as our cms. many academic departments at our campus were going through a similar process of website redesign and had already explored the cms options and had chosen drupal. this helped move us toward choosing drupal and taking advantage of a growing developer community on campus. two of the largest units on campus both chose drupal as their cms and have since been great partners for collaboration and peer support. drupal is a free, open-source cms (or content management framework) written in php with a mysql database backing it up. it is a small application of core modules with thousands of add-on modules available to increase functionality. drupal also has a very strong developer community and has been adopted by a growing number of libraries. we have found it to be very open and fluid, which is both a blessing and curse. for any one problem there can be dozens of differing solutions and modules to resolve it. the transition team the library created a core website implementation team consisting of a librarian project manager/developer, a web designer from the it department, and two librarian developers. the core team was supported by a server administrator and an it analyst. the it staff supported the technical aspects of drupal installation, backup, and maintenance. the librarian developers planned the content migration and managed the user interface design, layout, content, scope, and architecture. they needed to know the basics of how drupal works and needed to have much more access to the inner workings of drupal (e.g., modules, user permissions, etc.) than staff. the librarians also would train library staff, so needed to be able to teach and develop documentation and tailor instruction to specific staff needs. everyone who participated in the implementation team had many other competing responsibilities. the librarian developers had other projects and traditional duties such as collection development and reference services, so learning drupal and creating this new website was a part-time project and had to be integrated into existing workloads. tutorial ann hubble, deborah a. murphy, and susan chesley perry ann hubble (ahubble@ucsc.edu) is science

perry 191 and often eccentric organizational structures that were no longer meaningful. the previous website had accumulated pages that were a bit more freewheeling in design with a lack of consistent navigation and “look and feel.” adding another layer of complexity, our website changeover took place during a period of great organizational change and a severe budget crisis. surprisingly, what seemed at first a major drawback was actually somewhat helpful. with fewer people spread thinner and doing more work, there was less need to feel in control of individual empires, leading to more cooperation during the changeover. staff learning styles vary, and no one approach to drupal training will work for everyone, so we brought many of the lessons we have learned in our bibliographic instruction sessions to our staff training. for example, we focused training on repetition, reassurance, and patience, ensuring it was an active process with hands-on participation as well as a lecture or demonstration. we provided ample time for questions and invited staff to bring their own projects to work on during training sessions. though some staff only needed to learn a few applications within drupal to perform their jobs, most needed specialized instruction to do some departmental-specific task or action that now had a very different interface. we supplemented our large group by drop-in training sessions with specialized departmental sessions, custom-made documentation, individual hands-on training, e-mail updates on system changes, and regular presentations of new system features. not everyone will become a “born again” drupalista, but everyone should at least feel that they can get their work done using drupal. drupal has also meant changes not only in the way content is added to the website, but also in how we handle revisions and updates. in the past, we had a very siloed initially from the increasing interest in drupal at the campus level. they attended a two-day intensive drupal training course from a company called lullabot, which provided an in-depth technical foundation for our initial drupal installation. this level of technical training and content was not appropriate for the other librarian developers on our team. however, a more detailed, midlevel training would have benefited the librarian developers and moved the project forward at a faster pace. these librarian developers learned using a combination of resources, including free online content that covers core drupal skills, combined with a few carefully chosen professional in-person consultations and online training packages and books. drupal is not a static environment, so after the initial training there was still a need for regular updates and refresitishers. our transition team joined the drupal4lib discussion list and consulted with library colleagues using drupal in the northern california area. drupalcon conferences as well as online users groups were excellent places not only to learn but also to make contact with vendors and other developers. several of these resources are listed in the accompanying bibliography in appendix b. staff training by far our largest group of library drupal users was the fifty-plus library staff content contributors who were faced with learning a new approach to web development. drupal’s successful implementation was ultimately dependent on ensuring library staff would be able to create, edit, and manage thousands of library webpages using this new cms. this was a change for everyone in the library, not just a few. the new website meant leaving behind the comfort of routines created over the years, elaborate designs that had been developed, and various idiosyncratic transition planning with the goal of making our new site user-centered, we wanted to make data-driven decisions about design rather than what had ultimately devolved into the practice of decisions based on politics and committee negotiations. to that end, we took several approaches to gathering user data. we inventoried our current site and gathered usage statistics based on website analytics. we met with small campus focus groups who answered questions about library site searching. we created personas for user categories based on profiles of average users (e.g. first-year students, graduate students, faculty, community users, etc.). based on this data, we drafted web interface wireframes and began user testing. drupal implementation also included developing a safe and effective means of moving from a testing environment to a final, public production site. this deployment process is a crucial component of ensuring that we could both test new features and still provide a stable environment for our users. after extensive discussions and revisions we developed a process to experiment with new modules and themes in a way that does not overwrite our existing public site. the deployment process goes from development to staging to production. it is critical to be able to determine that a new module or update will not negatively affect the database. the process we follow from our sandbox site to our production site is described in more detail in appendix a. transition team training we had three types of drupal users within the library: system administrators, developers, and staff (the primary content editors); each group had its own training needs. the library project manager, web designer, and it systems administrators benefited 192 information technology and libraries | december 2011 appropriate for this particular subject. each tab can also be customized to display whichever records pertain to this subject area. how our dynamic displays were built cck (content construction kit) module content used in both the “article databases and research tools” and “subject guides” displays is held within a special record type we created using the content construction kit (cck) module. we called this special record, or content type, online resource. we defined fields within the online resource record to hold information about individual resources we want to either display on our website or keep track of internally. the fields we defined include the resource name, url (sometimes multiple urls), description, type of information (article database, dictionary, encyclopedia, etc.), and subject discipline. figure 3 shows what a portion of the online resource record for a particular database changes, it’s updated in a central record and immediately reflected in displays throughout the site. not only is it less work to update information, but we also can provide resources in more varied combinations and make them more findable for our users. figure 1 shows how the dynamically created “article databases and research tools” list appears to a user browsing our website. the default display lists these resources in alphabetical order. the user can display the same group of records sorted by other criteria just by clicking on the appropriate tab. if the “by subject” tab is selected, the resources are displayed under subject headings. selecting the “by type” tab lists the resources by resource types, such as dictionaries and encyclopedias, citation style guides, etc. our subject guides are also created using the same components used to build the “article databases and research tools” lists. figure 2 shows a portion of one of our subject guides. like the previous example, this portion of the guide is created dynamically, displaying only records permissions environment that limited editing to only those given specific permissions. we now have role-based ownership where everyone can edit everything so that we did not have to keep up a detailed list of who does what. initial concern that someone could write over or accidently delete pages was somewhat remedied by the drupal revisions history feature, which assists with version control. there have been a few pages where ownership is an issue, and we are still in the process of developing a system to ensure that pages are updated when there is no specific individual linked to a page. dynamic displays: article databases and subject guides as part of the move to drupal, we wanted to take advantage of the new environment to redesign some of the more specialized portions of our site. in particular, we hoped that drupal’s dynamic displays would help us to keep our site more current with less effort. with this in mind, we chose to focus on two of the most heavily used resources: our list of article databases and our library subject guides. we planned to transform these static, high-maintenance html pages into dynamic, easily maintained, and easily generated resources. we used a number of drupal modules to develop the library’s website, and these are described in more detail in appendix c. to redesign our list of article databases and our library subject guides, we relied heavily on three important modules: cck (content construction kit), views, and taxonomy. the interaction of these three modules is key to building dynamically created webpages. once these modules are configured, information is input just once. drupal does the work of pulling the right information from each resource to create dynamic displays. if information, such as a url figure 1. dynamic

if we could start over, we would have invested much more time in lessons learned learning drupal takes time our implementation team was comprised predominantly of librarians and list of defined fields looks like behind the scenes to the librarian web developer. some fields within the online resource record rely on a little further customization. the “type of information” field is defined via an allowed values list. figure 4 shows a portion of the values list we have defined for this particular field. the “subject, discipline, topic” field (figure 3) incorporates a taxonomy list that we first created using the taxonomy module. this taxonomy vocabulary allows us to later sort the resources dynamically in both the “article databases and research tools” (figure 1) and “subject guides” displays (figure 2). taxonomy module figure 5 shows the list of subject terms we created using the taxonomy module. terms are easily added, edited, and organized via this taxonomy display, available only to the web developers. views module–putting it all together to define how the online resource records are displayed to the user (figure 1), we use the views module. views allow us to define, sort, and filter these records for display. figure 6 shows what the “article databases and research tools” view of figure 1 looks like to the web developer. notice that “a–z,” “subjects,” and “by type” are listed in a box on the left side of the page. each of these tabs corresponds to a tab on the page that displays to the user. in this case, “a–z” is bold and is the active tab currently being defined for this display. display settings such as the record type used, number of records to display per page, specific fields to display, type of sorting, and url path for the webpage are defined here. figure 2. dynamic display: dynamic portion of a subject guide figure 3. cck module: online resource record: manage fields 194 information technology and libraries | december 2011 learning drupal basics and getting a better grasp of how drupal works as a cms. the architecture and database-driven paradigm of our new drupal site is a significantly different environment from our previous website’s html-designed pages and directory-and-folder organization. of particular importance for our site were three core modules: cck, views, and taxonomy. becoming proficient with these modules was a challenge, and we can’t emphasize enough the importance of good, basic training on their use. start small: identify small parts to bring over initially, the thought of moving our old website to drupal seemed insurmountable. bringing over static html pages was straightforward, but portions of the website (such as converting our database of online resources) took more intensive planning. the entire process became more manageable when we divided up the site and focused on drupalizing small parts at a time. this way we could focus on learning enough drupal to make these portions of the site work without being overwhelmed. project management software: document & share what you’ve done if we were to transition an entire website again we would recommend using some type of project management software before starting. none of the implementation team worked on this site full time. this project was added to our other full-time workload providing reference services, collection planning, teaching, digital projects, etc. during our project we tried several free products but were not satisfied with any of them. we felt that finding the right project management package could have made the website transition process much figure 4. cck module: allowed values list (type of information) figure 5. taxonomy module: subjects list selecting a web content management system for an academic library website | hubble, murphy, and perry 195from static and stale to dynamic and collaborative: the drupal difference | hubble, murphy, and perry 195 and the library is now in a much better position for future website design transitions, a process that will be much easier with so much less static content to migrate. for example, the look and feel of our entire website can be transformed by reconfiguring a few options within drupal. ultimately, the transition of the library website to a drupal environment was a very good thing, and we are glad we did it. it was difficult and messy at times, but our website is now more flexible, agile, adaptable, and better poised for change. epilogue since this article was submitted, the uc santa cruz university library website has moved to an entirely new campus theme. we note that having a drupal-based cms greatly aided this transition process. personas for librarians and content contributors and done more usability testing for non-developers. we found that training and teaching library staff the architecture and databasedriven paradigm of the new drupal culture has been a challenge and we still have varying levels of buy-in. conclusion we now have a consistent look and feel to our site, though there are still many things yet to do. now that we are more comfortable using drupal, we can focus on creating more dynamic content, such as staff lists, adding sidebars to pages, and so on. increasing the number of dynamically created pages will mean a more up-to-date site in general. though group authoring within the library is still a challenge, we continue to find ways to encourage collaboration. easier. documenting and sharing how we created elements of the site helped us replicate complex components and allowed us to collaborate more easily on various projects. test, test, test testing the website as we developed it was a crucial component of our work. modules also can interact with other modules in unpredictable ways, so we ultimately found that loading new modules on our sandbox site, a mirror of the library website, was a crucial step in determining compatibility as well as functionality with our existing site (appendix a). it’s essential to practice using a live site without bringing the real production website down. focus on essential modules: cck, views, taxonomy images, wysiwyg editors drupal comes with a set of core modules plus an ever-increasing number of specialized contributed modules. finding and installing the right contributed module that fits a particular need can sometimes be difficult. there are often myriad modules that can solve a problem. it takes time to find and test each one to see if it will actually function as needed, and not all modules work well with one another. focusing on the essential drupal core modules plus cck, views, and taxonomy will help reduce unnecessary development frustrations. staff are important though we created many personas for faculty, students, and community users, we should have created figure 6. views module: article databases and research tools view 196 information technology and libraries | december 2011 appendix a.

literacy: mapping libraries elizabeth thorne-wallington information technology and libraries | december 2013 53 abstract this paper examines the issue of universal library access by conducting a geospatial analysis of library location and certain socioeconomic factors in the st. louis, missouri, metropolitan area. framed around the issue of universal access to internet, computers, and technology (ict) for digital natives, this paper demonstrates patterns of library location related to race and income. this research then raises important questions about library location, and, in turn, how this impacts access to ict for young people in the community. objectives and purpose the development and diffusion of new media and digital technologies has profoundly affected the literacy experiences of today’s youth.1 young people today develop literacy through a variety of new media and digital technologies.2 the dissemination of these resources has also allowed for youth to have literacy-rich experiences in an array of different settings. ernest morrell, literacy researcher, writes, as english educators, we have a major responsibility to help future english teachers to redefine literacy instruction in a manner that is culturally and socially relevant, empowering, and meaningful to students who must navigate a diverse and rapidly changing world.3 this paper will explore how mapping and geographic information systems (gis) can help illuminate the cultural and social factors related to how and where students access and use new media literacies and digital technology. libraries play an important role in encouraging new media literacy development;4 yet access to libraries must be understood through social and cultural contexts. the objective of this paper is to demonstrate how mapping and gis can be used to provide rigorous analysis of how library location in st. louis, missouri, is correlated with socioeconomic factors defined by the us census including median household income and race. by using gis, the role of libraries in providing universal access to new media resources can be displayed statistically, both challenging and confirming previously held beliefs about library access. this analysis raises new questions about how libraries are distributed across the st. louis area and whether they truly provide universal and equal access. elizabeth thorne-wallington (ethornew@wustl.edu) is a doctoral student in the department of education at washington university in st. louis. mailto:ethornew@wustl.edu information technology and libraries | december 2013 54 literature review advances in technologies are transforming the very meaning of literacy.5 traditionally, literacy has been defined as the ability to understand and make meaning of a given text.6 the changing global economy requires a variety of digital literacies, which schools do not provide.7 instead, young people acquire literacy through a multitude of inand out-of-school experiences with new media and digital technology.8 libraries play a vital role in supporting new media literacy by offering out-of-school access and experiences. to understand the role that libraries play in offering access to new media literacy technologies, a few key concepts must be defined. first is the concept of the digital native. those born around 1980, who have essentially grown up with technology, are known as digital natives.9 digital natives are expected to have a base knowledge of technology and to be able to pick up and learn new technology quickly because of that base knowledge. digital natives have been exposed to technology from a young age and are adept at using a variety of digital technologies. the suggestion is that young people can quickly learn to make use of the new media and technology available in a specific location. key to any discussion of digital natives is the concept of the digital divide. the digital divide has been a central issue of education policy since the mid-1990s.10 early work on the digital divide was concerned primarily with equal access.11 more recently, however, the idea of a “binary digital divide” has been replaced by studies focusing on a multidimensional view of the digital divide.12 hargattai asserts that even among digital natives, there are large variations in internet skills and uses correlated with socioeconomic status, race, and gender.13 these variations call for a nuanced study examining social and cultural factors associated with new media literacy, including out-ofschool contexts. the concept of literacy and learning in out-of-school contexts has a strong historical context. hull and schultz provide a review of the theory and research on literacy in out-of-school settings.14 a variety of studies, including self-guided literacy activities, after-school programs, and reading programs were reviewed, and the significance of out-of-school learning opportunities was supported by these studies. importantly for the research here, research has also been done on the use of digital technology in out-of-school settings. lankshear and knobel examine out-of-school practices extensively with their work on new literacies.15 lankshear and knobel also make clear the complexity of out-of-school experiences among young people. students participate in nontraditional literacy activities such as blogging and remix in a variety of out-of-school contexts, from home computers to community-based organizations to libraries. most importantly, lankshear and knobel found that the students did connect what they learned in the classroom with these out-of-school activities. the connection between out-of-school literacies and in-school learning has also been studied. education policy researcher allan luke writes, the redefined action of governments . . . is to provide access to combinatory forms of enabling capital that enhance students’ possibilities of putting the kinds of practices, texts, and discourses social contexts of new media literacies: mapping libraries| thorne-wallington 55 acquired in schools to work in consequential ways that enable active position taking in social fields.16 collins writes about this relationship between inand out-of-school literacies. collins writes in her case study that there are a variety of “imports” and “exports” in terms of practices. that is, skill transaction works in both directions, with skills learned out of school used in school, and skills learned in school used out of school.17 skerett and bomer make this connection even more explicit when looking at adolescent literacy practices.18 their article examines how a teacher in an urban classroom drew on her students’ out-of-school literacies to inform teaching and learning in a traditional literacy classroom. the authors found that the teacher in their study was able to create a curriculum that engaged students by inviting them to use literacies learned in out-of-school settings. however, the authors write that this type of literacy study was taxing and time-consuming for both the teacher and the student. still, it is clear that connections between inand out-of-school literacies can be made. the role libraries play in making this connection has not been studied as extensively. yet it is clear that young people do use libraries to access technology. becker et al., found that nearly half of the nation’s 14 to 18 year olds had used a library computer within the past year. becker et al. additionally found that for poor children and families, libraries are a “technological lifeline.” among those below the poverty line, 61 percent used public library computers and the internet for educational purposes.19 tripp writes that libraries have long played an important role in helping people gain access to digital media tools, resources, and skills.20 tripp writes that libraries should capitalize on the potential of new media to engage young people. additionally, tripp argues that librarians need to develop skills to train young people to use new media. the idea that libraries are important in meeting the need is further supported by the recent grants, totaling $1.2 million, by the john d. and catherine t. macarthur foundation to build “innovative learning labs for teens” in libraries. this grant making was a response to president obama’s “educate to innovate” campaign, a nationwide effort to bring american students to the forefront in science and math.21 this literature review demonstrates that the body of research currently available focuses on digital natives and the digital divide, but that the research lacks the nuance needed to capture the complexity of social and cultural contexts surrounding the issue. this literature review further demonstrates both the importance of new media literacy and out-of-school learning, as well as the key role that libraries play in supporting these learning opportunities. the study provided here uses gis analysis to demonstrate important socioeconomic and cultural factors that surround libraries and library access. first, i describe the role of gis in understanding context. next, i describe the methods used in this paper. finally, i analyze the results and implications for the study. geographic information systems analysis in education there is a burgeoning body of research which uses geographic information systems (gis) to better understand socioeconomic and cultural contexts of education and literacy issues.22 information technology and libraries | december 2013 56 there are several key works that link geography and social context. lefebvre defines space as socially produced, and he writes that space embodies social relationships shaped by values and meanings. he describes space as a tool for thought and action or as a means of control and domination. lefebvre writes that there is a need for spatial reappropriation in everyday urban life. the struggle for equality, then, is central to the “right of the city.”23 the unequal distributions of resources in the city help to maintain social and economic advantaged positions, which is important to the analysis here of library access. this unequal distribution of resources continues today. de souza briggs and others write that there is clear geographical segregation in american cities today.24 this is seen in housing choice, racial attitudes, and discrimination, as well as metropolitan development and policy coalitions. in the conclusion of his book, de souza briggs writes that housing choice is limited for low-ses minorities, and these limitations produce myriad social effects. again, this finding is important to the contexts of where libraries are located. jargowsky writes of similar findings.25 like de souza briggs, jargowsky focuses on the role that geography plays in terms of neighborhood and poverty. jargowsky even finds social characteristics of these neighborhoods: there is a higher prevalence of single-parent families, lower educational attainment, a higher level of dropouts, and more children living in poverty. important here, though, is that all such characteristics can be displayed geographically, which means that varying housing, economic, and social conditions can be displayed with library locations. soja goes beyond the geographic analysis offered by de souza briggs and jargowsky and writes that space should be applied to contemporary social theory.26 soja found that spatiality should be used in terms of critical human geography to advance a theory of justice on multiple levels. he writes that injustice is spatially construed and that this spatiality shapes social injustice as much as social injustice shapes a specific geography. this understanding, then, shapes how i approach the study of new media literacies as influenced by cultural and social factors. these factors are particularly prevalent in the st. louis, missouri, area. colin gordon reiterates the arguments of lefbvre jargowsky and de souza briggs in arguing that st. louis is a city in decline.27 by providing maps that project housing policies, gordon is able to provide a clear link between historical housing policies such as racial covenants and current urban decline. gordon is able to show that vast populations are moving out of st. louis city and into the county, resulting in a concentration of minority populations in the northern part of the city. gordon argues that the policies and programs offered by st. louis city have only exacerbated the problem and led to greater blight.28 in terms of literacy, morrell makes the most explicit connection between literacy and mapping with a study that used a community-asset mapping activity to make the argument that teachers need to make an explicit connection between literacy at school and the new literacies experienced in the community.29 the significance of this is that gis can be used to illuminate the social and economic contexts of new media literacy opportunities as well, which in turn could help inform social dialogue about the availability of and access to informal education opportunities for new media literacy. social contexts of new media literacies: mapping libraries| thorne-wallington 57 methods and data the gis analysis performed here concerns library locations in the st. louis metropolitan area, including st. louis city and st. louis county. the st. louis metropolitan area was chosen because of past research mapping the segregation of the city, largely because the city and county are so clearly segregated racially and economically along the north–south line. this segregation is striking when displayed geographically and illuminating when mapped with library location. maps were created using tiger files (www.census.gov/geo/maps-data/data/tiger.html) and us census data (http://factfinder2.census.gov/faces/nav/jsf/pages/index.xhtml), both freely available to the public via internet download. libraries were identified using the st. louis city library’s “libraries & hours” webpage (www.slpl.org/slpl/library/article240098545.asp), the st. louis county library “locations & hours” webpage (www.slcl.org/about/hours_and_locations), google maps (www.maps.google.com), and the yellow pages for the st. louis metropolitan area (www.yellowpages.com). the address of each library was entered into itouchmap (http://itouchmap.com ) to indentify the latitude and longitude of the library. a spreadsheet containing this information was then loaded into the gis software and displayed as x–y data. the maps were then displayed using median household income, african american population, and latino and hispanic population as obtained from the us census at census tract level. for median household income, the data was from 1999. for all other census data, the year was 2010. for district-level data, communication arts data from the missouri department of elementary and secondary education (modese) website (http://dese.mo.gov/dsm ), was entered into microsoft excel, and then displayed on the maps. the data is district level, representing all grades tested for communication arts across all district schools. the modese data was from 2008, the most recent year available at the time the analysis was performed. the communication arts data was taken from the missouri assessment program test. this test is given yearly across the state to all public school students. the state then collects the data and makes it available at the state, district, and school level. the data used here is district-level data. scores are broken into four categories: advanced, proficient, basic, and below basic. the groups for proficient and advanced were combined to indicate the district’s success on the map test. these are the two levels generally considered acceptable or passing by the state.30 before looking at patterns of library location and these socioeconomic and educational factors, density analysis was performed on the library locations using esri arcgis software, version 9.0, to analyze whether clustering was statistically significant. this analysis was used to demonstrate whether libraries were clustered in a statistically significant pattern, or if location was random. the nearest neighbor tool of arcgis was used to determine if a set of features, in this case the libraries, shows a statistically significant level of clustering. this was done by measuring the distance from each library to its single nearest neighbor and calculating the average distance of all the measurements. the tool then created a hypothetical set of data with the same number of features, but placed randomly within the study area. then an average distance was calculated for these features and compared to the real data. that is, a hypothetical random set of locations was compared to the set of actual library locations. a near-neighbor index was produced, which expresses the ratio of the observed distance divided by the distance from the hypothetical data, thus comparing the two sets.31 this score was then standardized, producing a z-score, reported below in the results section. http://www.census.gov/geo/maps-data/data/tiger.html http://factfinder2.census.gov/faces/nav/jsf/pages/index.xhtml http://www.slpl.org/slpl/library/article240098545.asp http://www.slcl.org/about/hours_and_locations http://www.maps.google.com/ http://www.yellowpages.com/ http://dese.mo.gov/dsm information technology and libraries | december 2013 58 results and conclusions using the nearest neighbor tool produced a z-score of -3.08, showing that the data is clustered beyond the 0.01 significance level. this means that there is a less than 1 percent chance that library location would be clustered to this degree based on chance. knowing, then, that library location is not random, we can now examine socioeconomic patterns of the areas where libraries are located. figure 1 shows library location and population of individuals under the age of 18 at the census tract level for st. louis city and county, using data from the 2010 us census. to clarify, the city and county are divided by the bold black line crossing the middle of the map, the only such boundary in figure 1, where the county is the larger geographic area. library location is important because previous research shows that young people use informal learning environments to access new media technologies,32 and libraries are a key informal learning environment.33 this map demonstrates, however, that libraries are not located in census tracts with the highest populations of individuals under the age of 18 in st. louis city and county. in fact, for all the tracts with the highest number of individuals under the age of 18, there are zero libraries located in these tracts. this is especially concerning given that young people may have less access to transportation, so their access of facilities in neighboring census tracts may be quite limited. figure 1. number of individuals under the age of 18 by census tract and library location in st. louis city and st. louis county. source: 2010 us census. social contexts of new media literacies: mapping libraries| thorne-wallington 59 figure 2 includes maps showing library locations in st. louis city and county in terms of poverty and race by census tract level, as well as act score by district, represented by the bold lines, where st. louis city is represented by a single district, the st. louis public school district. median household income in indicated by the gray shading, with white areas not having data available. first, census tracts with low median household income are clustered in the northern part of the city and county. there are four libraries in the northern half of the city, and eleven libraries in the central and southern parts of the city. there are fewer libraries in the census tracts with low median household income. figure 2. median household income, act score, and library location, st. louis city and county. source: 2010 us census and missouri department of elementary and secondary education, 2010, www.modese.gov. while the nearest neighbor analysis has already demonstrated the libraries are significantly clustered, the maps seem to suggest the pattern of that clustering. this is especially concerning given the report by becker that 61 percent of those living below the poverty line use libraries to access the internet.34 first, in terms of median household income, it does appear that many libraries are located in higher income areas of the city and county. while the libraries appear to be http://www.modese.gov/ information technology and libraries | december 2013 60 clustered centrally, and particularly near major freeways, there appear to be libraries in many of the higher income census tracts. adding to the concern of location is that of access to these library locations. for those living below the poverty line, transportation is often a prohibitive cost, so access from public transportation should also be a major concern for libraries. additionally, in a pattern repeated in figure 4, the location of libraries does not appear to have any effect on act scores, but there are clearly higher act scores in wealthier areas of the city and county. this is not to say that there is a statistical relationship between act score and library location, but rather to look at the spatial patterns of each in order to note similarities and differences in these patterns. figure 3 shows library location by race, including african american or black and hispanic or latino. first, it is important to note that patterns of race in st. louis have been carefully documented by gordon.35 the st. louis area is clearly a highly segregated region, which makes the social contexts of libraries in the st. louis area even more important. this map demonstrates that while there are many libraries in the northern parts of st. louis city and county, none of these libraries is located in the census tracts with the highest populations of those identifying themselves as african american or black in either the city or county. this raises questions about the inequality of access to the libraries. on the other hand, the densest populations of those identifying themselves as hispanic or latino are in the southern part of the city, but not the county. there is a library located in one of those tracts. it appears the areas with higher concentrations of african americans or blacks have fewer libraries, while areas with the higher concentrations of latinos or hispanics are located in the southern parts of the city that do have libraries. it is important to note, however, that the concentrations of latinos and hispanics is quite low, and those areas are majority white census tracts. as noted above, beyond location, access from public transportation is also an important issue. at the same time, the clustering and patterns shown on these maps raise key issues about access based on income and race. libraries are not located in areas with low median household income or in areas with high concentrations of african americans or blacks. this raises serious questions about why libraries are located where they are, and whether the individuals located in these areas have equal access to library resources, particularly new media technologies. social contexts of new media literacies: mapping libraries| thorne-wallington 61 figure 3. african american or black and hispanic, library location, st. louis city and county. source: 2010 us census. the final map raises a slightly different issue, one of test scores and student achievement. figure 4 shows library location by percent proficient or advanced on the missouri achievement program test by district. beyond the location of the libraries, one factor that stands out is that the areas with the lowest percent proficient or advanced are also the areas with the lowest median household income and the highest percentage of those identifying as african american or black. here an interesting pattern emerges. while there are many libraries in the city and northern part of the county, the percent proficient or advanced on the communication arts portion of exam is quite low (20–30 percent). on the other hand, in the western part of the county, there are few libraries, but the percent proficient or advanced is at its highest level. this suggests that there may not be a strong connection between achievement on the map exam and library location, similar to the lack of relationship seen in between act average score and library location in figure 2. at the same time, there does appear to be a correlation between race, income, and test scores. this correlation is noted throughout the literature on student achievement.36 clearly, these maps raise important questions such as how and why libraries are located in a certain area, who uses libraries in a given area, as well as what other informal learning environments and community assets exist in these areas. what is made clear by the maps, though, is that gis can be used as a tool to help understand the context of new media literacy. information technology and libraries | december 2013 62 figure 4. proficient or advanced, communication arts map by district, 2009, and library location. source: missouri department of elementary and secondary education, 2010, www.modese.gov. significance these results demonstrate that gis can be used to illuminate the social, cultural, and economic complexity that surrounds informal learning environments, particularly libraries. this can help demonstrate not only where young people have the opportunity to use new media literacy, but also the complex contextual factors surrounding those opportunities. paired with traditional qualitative and quantitative work, gis can provide an additional lens for understanding new media literacy ecologies, which can help inform dialogue about this topic. for the results of this study, there does appear to be a relationship between library location and race and income. this study illuminates the complex contextual factors affecting libraries. because of the important role that libraries can play in offering young people out of school learning opportunities, particularly in terms of access to new media resources, these contextual factors are important to ensuring equal access and opportunity for all. http://www.modese.gov/ social contexts of new media literacies: mapping libraries| thorne-wallington 63 references 1. ernest morrell,

stamper information technology and libraries | september 2012 85 abstract there is very little public data on usage of digitized library collections. new methods for promoting and sharing digitized collections are created all the time, but very little investigation has been done on the effect of those efforts on usage of the collections on library websites. this study attempts to measure the effects of reposting a collection on flickr on use of the collection in a library-run institutional repository (ir). the results are inconclusive, but the paper provides background on the topic and guidance for future efforts. introduction inspired by the need to provide relevant resources and make wise use of limited budgets, many libraries measure the use of their collections. from circulation counts and in-library use studies of print materials, to increasingly sophisticated analyses of usage of licensed digital resources, the techniques have changed even as the need for the data has grown. new technologies have simultaneously presented challenges to measuring use, and allowed those measurements to become more accurate and more relevant. in spite of the relative newness of the digital era, “librarians already know considerably more about digital library use than they did about traditional library use in the print environment.”1 arl’s libqual+,2 one of the most widelyadopted tools for measuring users’ perceptions of service quality, has recently been joined by digiqual and mines for libraries. these new statsqual tools3 extend the familiar libqual focus on users into the digital environment. there are tools and studies for seemingly every type of licensed digital content, all with an eye toward better understanding their users and making better-informed collection management decisions. those same tools and studies for measuring use of library-created digital collections are conspicuous in their absence. almost two decades into library collection digitization programs, there is not a significant body of literature on measuring use of digitized collections. a number of articles have been written about measuring usage of library websites in general; arendt and wagner4 is a recent example. in one of the few studies to specifically measure use of a digitized collection, herold5 uses google analytics to uncover the geographical location of users of a digitized archival image collection. otherwise, a literature search on usage studies uncovers very little. less formal communication channels are similarly quiet, and public usage data on digitized collections on library sites is virtually nonexistent. commercial sites for disseminating and sharing melanie schlosser (schlosser.40@osu.edu) is digital publishing librarian and brian stamper (stamper.10@osu.edu) is administrative associate, the ohio state university libraries, columbus, ohio. mailto:schlosser.40@osu.edu mailto:stamper.10@osu.edu information technology and libraries | september 2012 86 digital media frequently display simple use metrics (image views, for example, or file downloads) alongside content; such features do not appear on digitized collections on library sites. usage and digitization projects digitized library collections are created with an eye toward use from their early planning stages. an influential early clir publication on selecting collections for digitization written by a harvard task force6 included current and potential use of the analog and digitized collection as a criterion for selection. the factors to be considered include the quantitative (“how much is the collection used?”) and the qualitative (“what is the nature of the use?”). more than ten years later, ooghe and moreels7 find that use is still a criterion for selection of collections to digitize, tied closely to the value of the collection. facilitating discovery and use of the digitized collection is a major consideration during project development. payette and rieger8 is an early example of a study of the needs of users in digital library design. usability testing of the interface is frequently a component of site design; see jeng9 for a good overview of usability testing in the digital library environment. increasing usage of the digitized collection is also a major theme in metadata research and development. standards such as the open archives initiative’s protocol for metadata harvesting10 and object reuse and exchange11 are meant to allow discovery and reuse of objects in a variety of environments, and the linked data movement promises to make library data even more relevant and reusable in the world wide web environment.12 digital collection managers have also found more radical methods of increasing usage of their collections. inserting references into relevant wikipedia articles has become a popular way to drive more users to the library’s site.13 some librarians have taken the idea a step further and have begun reposting their digital content on third-party sites. the smithsonian pioneered one reposting strategy in 2008 when they partnered with flickr, the popular photo-sharing site, to launch flickr commons.14 the commons is a walled garden within flickr that contains copyrightfree images held by cultural heritage institutions such as libraries, archives, and museums. each partner institution has its own branded space “photostream” in flickr parlance organized into collections and sets. this model aggregates content from different organizations and locates it where users already are, but it still maintains the traditional institution/collection structure. flickr commons has been, by all measures, a very successful experiment in sharing collections with users. the smithsonian,15 the library of congress,16 the alcuin society,17 and the london school of economics18 have all written about their experiences with the commons. stephens19 and michel and tzoc20 give advice on how libraries can work with flickr, and garvin21 and vaughan22 take a broad view of the project and the partners. another sharing strategy is beginning to emerge, where digital collection curators contribute individual or small groups of images to thematic websites. a recent example is pets in collections,23 a whimsical tumblr photo blog created by the digital collections librarian at bryn mawr college. learning to share: measuring use of a digitized collection on flickr and in the ir| schlosser and stamper 87 the site’s description states, “come on if you work in a library, archive, or museum, you know you’ve seen at least one of these a seemingly random image of that important person and his dog or a man and a monkey wearing overalls … so now you finally have a place to share them with the world!” the site requires submissions to include only the image and a link back to the institution or repository that houses it, although submitters may include more information if they choose. although more lighthearted than most traditional library image collections, it still performs the desired function of introducing users to digital collections they may never have encountered otherwise. clearly, these creative and thoughtful strategies are not dreamed up by digital librarians unconcerned with end use of their collections, so why do stewards of digitized collections so rarely collect, or at least publicly discuss, statistics on the use of their content? the one notable exception to this may shed some light on the matter. institutional repositories (irs) have been the one area of non-licensed digital library content where usage statistics are frequently collected and publicized. dspace,24 the widely-adopted ir platform developed by mit and hewlett-packard, has increasingly sophisticated tools for tracking and sharing use of the content it hosts. digital commons,25 the hosted ir solution created by bepress, provides automated monthly download reports for scholars who use it to archive their content. the development of these features has been driven by the need to communicate value to faculty and administrators. encouraging participation by faculty has been a major focus of ir managers since the initial ‘build it and they will come’ optimism faded and the challenge of adding another task to already busy faculty schedules became clear.26 having a clear need (outreach) and a defined audience (participating scholars) has led to a thriving program of usage tracking in the ir community. the lack of an obvious constituency and the absence of pointed questions about use in the digitized collections world have, one suspects, led to the current dearth of measurement tools and initiatives. still, questions about use do arise, particularly when libraries undertake laborintensive usability studies or venture into the somewhat controversial landscape of sharing library-created digital objects on third party sites.27 anecdotally, the thought of sharing library content elsewhere on the web also raises concerns about loss of context and control, as well as a fear of ‘dilution’ of the library’s web presence. “if patrons can use the library’s collections on other sites,” a fellow librarian once exclaimed, “they won’t come to the library’s website anymore!” without usage data, we cannot adequately answer questions about the value of our projects or the way they impact other library services. justification for study and research questions there were three major motivations for this project. first, inspired by the success of the flickr commons project, we wanted to explore a method for sharing our collections more widely. an image collection and a third-party image-sharing platform were an obvious choice, since image display is not a strength of our dspace-based repository. flickr is currently a major presence in information technology and libraries | september 2012 88 the image sharing landscape, and the existence of the commons was an added incentive for choosing flickr as our platform. second, the collection we selected for the project (described more fully below) is not fully described, and we wanted to take advantage of flickr’s annotation tools to allow user-generated metadata. since further description of the images would have required an unusual depth of expertise, we were not optimistic that we would receive much useful data, and in fact we did not. still, we lost nothing by asking, and gained familiarity with flickr’s capabilities for metadata capture. the final motivation for the project, and the focus of the study, was the desire to investigate the effect of third-party platform sharing of a local collection on usage of that collection on library sites. the data gathered were meant partly to inform our local practice, but also to address a concern that may hold librarians back from exploring such means of increasing collection usage the fear that doing so will divert traffic from library sites. we suspected that sharing collections more widely would actually increase usage of the items on library-owned sites, and the study was developed to explore the issue in a rigorous way. the research question for this study was: does reposting digitized images from a library site to a third-party image sharing site have an effect on usage of the images on the library site? about the study platforms for the study, the images were submitted to two different platforms the knowledge bank (kb),28 a library-managed repository, and flickr, a commercial image sharing site. the kb is an institutional repository built on dspace software with a manakin (xml-based) user interface. established in 2005, it holds more than 45,000 items, including faculty and student research, gray literature, institutional records, and digitized library collections. image collections like the one used in this study make up a small percentage of the items in the repository. in the kb’s organizational structure, the images in the study were submitted as a collection in the library’s community, under a sub-community for the special collection that contributed them. each image was submitted as an item consisting of one image file and dublin core metadata.29 the project originally called for submitting the images to flickr commons, but the commons was not accepting new partners during the study period. instead, we created a standard flickr pro account for the libraries, while following the commons guidelines in image rights and settings. in contrast to dspace’s community/sub-community/collection structure, flickr images are organized in sets, sets belong to collections, and all images make up the account owner’s photostream. a set was created for the images, with accompanying text giving background information and inviting users to contribute to the description of the images.30 the images were accompanied by the same metadata as the items in the kb, but the files themselves were higher resolution, to take advantage of flickr’s ability to display a range of sizes for each image. all items in the set were publicly learning to share: measuring use of a digitized collection on flickr and in the ir| schlosser and stamper 89 available for viewing, commenting, and tagging, and each image was accompanied by links back to the kb at the item, collection, and repository level. the collection the choice of a collection for the study was limited by a number of factors. first, and most obviously, it needed to be an image collection. second, it needed to be in the public domain, both to allow our digitization and distribution of the images, and also to satisfy flickr commons’ “no known copyright restrictions” requirement.31 this could be accomplished either by choosing a collection whose copyright protections had expired, or by removing restrictions from a collection to which the libraries owned the rights. third, the curator of the collection needed to be willing and able to post the images on a commercial site. this required not only an open-minded curator, but also a collection without a restrictive donor agreement or items containing sensitive or private information. finally, we wanted the collection to be of broad public interest. the collection chosen for the study was a set of 163 photographs from osu’s charles h. mccaghy collection of exotic dance from burlesque to clubs, held by the jerome lawrence and robert e. lee theatre research institute.32 the photographs, mainly images of burlesque dancers, were published on cabinet and tobacco cards in the 1890s, putting them solidly in the public domain. figure 1.

share: measuring use of a digitized collection on flickr and in the ir| schlosser and stamper 87 methodology phases the study took place in 2011 and was organized in three ten-week phases. for the first phase (january 31 through april 11), the images were submitted to the kb. the purpose of this phase was to provide a baseline level of usage for the images in the repository. in phase two (april 12 through june 20), half of the images were randomly selected and submitted to flickr (group a). the purpose of this phase was to determine what effect reposting would have on usage of items in the repository both on those images that were reposted, and on other images in the same collection that had not been reposted. in phase three (june 21 through august 29), the rest of the images (group b) were submitted to flickr. in this phase, we began publicizing the collection. publicity consisted of sharing links to the collection on social media and sending emails to scholars in relevant fields via email lists. these efforts led to further downstream publicity on popular and scholarly blogs.33 data collection the unit of measurement for the study was views of individual images. to understand the notion of a “view,” we must contrast two different ways that an image may be viewed in the knowledge bank. each image in the collection has an individual web page (the item page) where it is presented along with metadata describing it. in addition, from that page a visitor may download and save the image file itself (in this collection, a jpeg). in the former case, the image is an element in a web page, while in the latter it is an image file independent of its web context. search engines and other sources commonly link directly to such files, so it is not unusual for a visitor to download a file without ever having seen it in context. in light of this, we produced two data sets, one for visits to item pages, and another for file downloads. depending on one’s interpretation, either could be construed as a “view.” ultimately there was little distinction in usage patterns between the two types of measure. the data were generated by making use of dspace’s apache solr-based statistics system, which provides a queryable database of usage events. for each item in the study, we made two queries; one for per-day counts of item page views, and another for per-day counts of image file downloads (called “bitstream” downloads in dspace parlance.) in both cases, views that came from automated sources such as search engine indexing agents were excluded from our counts. views of the images in flickr were noted and used as a benchmark, but were not the focus of the study. unlike cumulative views, which are tabulated and saved indefinitely, flickr saves daily view numbers for only thirty days. as a result, daily view numbers for most of the study period were not available for analysis, and the discussion of the trends in the flickr data is necessarily anecdotal. information technology and libraries | september 2012 88 results at the end of the study period, the data showed very little usage of the collection in the repository. this lack of usage was relatively consistent through the three phases of the study, and in rough terms translates to less than one view of each item per day. of the two ways of measuring an image "view" either by counting views of the web page where the item can be found or by counting how many times the image file was downloaded there was little distinction. knowledge bank item pages received between 5 and 38 views per item, while files were downloaded between 5 and 34 times. further, there were no significant differences in number of views received between the first group released to flickr and the second. kb item page views image file downloads min median max min median max group a (images released to flickr in phase ii) 5 10 35 5 9 25 group b (images released to flickr in phase iii) 6 10 38 4 9 34 table 1. the items in the study are divided into group a and group b, depending on when the images were placed on flickr. this table shows that both groups received similar traffic over the course of the study, with items having between 5 and 38 views in both groups, with a median of 10 for both, and between 4 and 34 downloads, with a median of 9 for both groups. the items attracted more visitors on flickr, with the images receiving between 100 and 600 views each. with a few exceptions, the items that appeared towards the beginning of the set (as viewed by a user who starts from the set home page) received more views than items towards its end. this suggests a particular usage pattern start at the beginning, browse through a certain number of images, and navigate away. a more significant trend in the flickr data is that most views of the images came after publicity for the collection began (approximately midway through the third phase of the study). again, the lack of daily usage numbers on flickr makes it impossible to demonstrate the publicity ‘bump,’ but it was dramatic. we witnessed a similar, if smaller, ‘bump’ in usage of the items in the kb after publicity started. we were also able to identify 65 unique visitors to the kb who came to the site via a link on flickr, out of 449 unique visitors overall. of those who came to the kb from flickr, 31 continued on to other parts of the kb, and the rest left after viewing a single item or image. learning to share: measuring use of a digitized collection on flickr and in the ir| schlosser and stamper 89 discussion with so little data, we cannot reliably answer the primary research question. reposting certainly does not seem to have lowered usage of the items in the kb, but the numbers of views in all phases were so small as to preclude drawing meaningful conclusions. a larger issue is the fact that much of the usage came immediately following our promotional efforts. this development complicated the research in a number of ways. first, because the promotional emails and social media messages specifically pointed users to the collection in flickr, it is impossible to know how the use may have differed if the primary link in the promotion had been to the knowledge bank. would the higher use seen on flickr simply have transferred to the kb? would the unfamiliarity and non-image-centric interface of the knowledge bank have thwarted casual users in their attempt to browse the collection? the centrality of the promotion efforts also suggests that one of the underlying assumptions of the study may have been wrong. this research project was premised on the idea that an openly available collection on a library website will attract a certain number of visitors (number dependent on the popularity and topicality of the subject of the collection) who find the content spontaneously via searching and browsing. placing that same content on a third-party site could theoretically divert a percentage of those users, who would then never visit the library’s site. the percentage of users diverted would likely depend on how many more users browse the third party site than the library site, as well as the relative position of the two in search rankings. the mccaghy collection should have been a good candidate for this type of use pattern. flickr is certainly heavily used and browsed, and burlesque, while not currently making headlines, is a subject with fairly broad popular appeal. the fact that users did not spontaneously discover the collection on either platform in significant numbers suggests that this may not be how discovery of library digitized collections works. it is not surprising that email lists and social media should drive larger numbers of users to a collection than happenstance the power of link curation by trusted friends via informal communication channels is well known. what is surprising is that it was the only significant use pattern in evidence. the primary takeaway is that promotion is key. if we do not promote our collections to the people who are likely to be interested in them, barring a stroke of luck, it is unlikely that they will be found. anecdotally, promotional efforts are often an afterthought in digital collections work a pleasant but unnecessary ‘extra.’ in our environment, the repository staff often feel that promotion is the work of the collection owner, who may not think of promoting the collection in the digital environment, nor know how to do so. as a result, users who would benefit from the collections simply do not know they exist. these results also suggest that librarians worried about the consequences of sharing their collections on third party sites may be worrying about the wrong thing. the sheer volume of information on any given topic makes it unlikely that any but the most dedicated researcher will information technology and libraries | september 2012 90 explore all available sources. most other users are likely to rely on trusted information sources (traditional media, blogs, social networking sites) to steer them towards the items that are most likely to interest them. instead of wondering if users will still come to the library’s site if the content is available elsewhere, perhaps we should be asking of our digital collections, “is anyone using them on any site?” and if the answer is no, the owners and caretakers of those collections should explore ways to bring them to the attention of relevant audiences. conclusion as a usage study of a collection hosted on a library site and a commercial site, this project was not a success. flawed assumptions and a lack of usable data resulted in an inability to address the primary research question in a meaningful way. however, it does shed light on the questions that motivated it. are our digitized collections being used? what effect do current methods of sharing and promotion have on that use? librarians working with digitized collections have fallen behind our colleagues in the print and institutional repository arenas in measuring use of collections, but we have the same needs for usage data. in the current climate of heightened accountability in higher education and publicly funded institutions, we need to demonstrate the value of what we do. we need to know when our efforts to promote our collections are working, and determine which projects have been most successful and merit continued development. and as always, we need to share our results, both formally and informally, with our colleagues. measuring use of digital resources is challenging, and obtaining accurate usage statistics requires not only familiarity with the tools involved, but also some understanding of the ways in which the numbers can be unrepresentative of actual use. the organizations that do collect usage statistics on their digitized collections should share their methods and their results with others to help foster an environment where such data are collected and used. next steps in this area could take the shape of further research projects, or simply more visible work collecting usage statistics on digital collections. of greatest utility to the field would be data demonstrating the relative effectiveness of different methods of increasing use. do labor-intensive usability studies deliver returns in the form of increased use of the finished site? which forms of reposting generate the most views? what types of publicity are most effective in bringing users to collections? how does use of a collection change over time? there are also more policy-driven questions to be answered. for example, should further investment in a collection or site be tied to increasing use of low-traffic collections, or capitalizing on success? differences in topic, format, and audience make it difficult to generalize in this area, but we can begin building a body of knowledge that helps us learn from each other’s successes and failures. learning to share: measuring use of a digitized collection on flickr and in the ir| schlosser and stamper 91 references 1 brinley franklin, martha kyrillidou, and terry plum.

content | deridder 71 in accordance with the current best practices.8 for those producers of content who are not able to meet the requirements of ingest, or who do not have access to an oais archive provider, what are the options? with the recent downturn in the economy, the availability of staff and the funding for the support of digital libraries has no doubt left many collections at risk of abandonment. is there a method for preparation of content for longterm storage that is within the reach of existing staff with few technical skills? if the content cannot get to the safe harbor of a trusted digital library, is it consigned to extinction? or are there steps we can take to mitigate the potential loss? the oais model incorporates six functional entities: ingest, data management, administration, preservation planning, archival storage, and access.9 of these six, only archival storage is primary; all the others are useless without the actual content. and if the content cannot be accessed in some form, the storage of it may also be useless. therefore the minimal components that must be met are those of archival storage and some form of access. the lowest cost and simplest option for archival storage currently available is the distribution of multiple copies dispersed across a geographical area, preferably on different platforms, as recommended by the current lockss initiative,10 which focuses on bit-level preservation.11 private lockss network models (such as the alabama digital preservation network)12 are the lowest-cost implementation, requiring only hardware, membership in lockss, and a small amount of time and technical expertise. reduction of the six functional entities to only two negates the need in contrast, other leaders of the digital preservation movement have been stating for years that benign neglect is not a workable solution for digital materials. eric van de velde, director of caltech’s library information technology group, stated that the “digital archive must be actively managed.”3 tom cramer of stanford university agrees: “benign neglect doesn’t work for digital objects. preservation requires active, managed care.”4 the digital preservation europe website argues that benign neglect of digital content “is almost a guarantee that it will be inaccessible in the future.”5 abby smith goes so far as to say that “neglect of digital data is a death sentence.”6 arguments to support this statement are primarily those of media or data carrier storage fragility and obsolescence of hardware, software, and format. however, the impact of these arguments can be reduced to a manageable nightmare. by removing as much as possible of the intermediate systems, storing open-source code for the software and operating system needed for access to the digitized content, and locating archival content directly on the file system itself, we reduce the problems to primarily that of format obsolescence. this approach will enable us to forge ahead in the face of our lack of resources and our rather desperate need for rapid, cheap, and pragmatic solutions. current long-term preservation archives operating within the open archival information system (oais) model assume that producers can meet the requirements of ingest.7 however, the amount of content that needs to be deposited into archives and the expanding variety of formats and genres that are unsupported, are overwhelming the ability of depositors to prepare content for preservation. andrea goethals of harvard proposed that we revisit assumptions of producer ability to prepare content for deposit benign neglect: developing life rafts for digital content i n his keynote speech at the archiving 2009 conference in arlington, virginia, clifford lynch called for the development of a benign neglect model for digital preservation, one in which as much content as possible is stored in whatever manner available in hopes of there someday being enough resources to more properly preserve it. this is an acknowledgment of current resource limitations relative to the burgeoning quantities of digital content that need to be preserved. we need low cost, scalable methods to store and preserve materials. over the past few years, a tremendous amount of time and energy has, sensibly, been devoted to developing standards and methods for best practices. however, a short survey of some of the leading efforts clarifies for even the casual observer that implementation of the proposed standards is beyond many of those who are creating or hosting digital content, particularly because of restrictions on acceptable formats, requirements for extensive metadata in specific xml encodings, need for programmers for implementation, costs for participation, or simply a lack of a clear set of steps for the uninitiated to follow (examples include: planets, premis, dcc, caspar, irods, sound directions, hathitrust).1 the deluge of digital content coupled with the lack of funding for digital preservation and exacerbated by the expanding variety of formats, makes the application of extensive standards and extraordinary techniques beyond the reach of the majority. given the current circumstances, lynch says, either we can seek perfection and store very little, or we can be sloppy and preserve more, discarding what is simply intractable.2 communications jody l. deridder (jlderidder@ua.edu) is head, digital services, university of alabama. jody l. deridder 72 information technology and libraries | june 2011 during digitization is that developing digital libraries usually have a highly chaotic disorganization of files, directory structures, and metadata that impede digital preservation readiness.19 if the archival digital files cannot be easily and readily associated with the metadata that provides their context, and if the files themselves are not organized in a fashion that makes their relationships transparent, reconstruction of delivery at some future point is seriously in question. underfunded cultural heritage institutions need clear specifications for file organization and preparation that they are capable of meeting without programming staff or extensive time commitments. particularly in the current economic downturn, few institutions have the technical skills to create mets wrappers to clarify file relationships.20 one potential solution is to use the organization of files in the file system itself to communicate clearly to future archivists how the files relate to one another. at the university of alabama, we have adopted a standardized file naming system that organizes content by the holding institution and type, collection, item, and then sequence of delivery (see figure 1). the file names are echoed in the file system: top level directories match the holding institution number sequence, secondary level directory names match the assigned collection number sequence, and so forth. metadata and documentation are stored at whatever level in the file system corresponds to the files to which they apply, and these text and xml files have file names that also correspond to the files to which they apply, which assists further in identification (see figure 2).21 by both naming and ordering the files according to the same system, and bypassing the need for databases, complex metadata schemes and software, we leverage the simplicity of the file system to bring order to chaos and to enable our content to be easily reconstructed by future systems. take and manage the content is still uncertain. the relay principle states that a preservation system should support its own migration. preserving any type of digital information requires preserving the information’s context so that it can be interpreted correctly. this seems to indicate that both the intellectual context and the logical context need to be provided. context may include provenance information to verify authenticity, integrity, and interpretation;17 it may include structural information about the organization of the digital files and how they relate to one another; and it should certainly include documentation about why this content is important, for whom, and how it may be used (including access restrictions). because the cost of continued migration of content is very high, a method of mitigating that cost is to allow content to become obsolete but to support sufficient metadata and contextual information to be able to resurrect full access and use at some future time—the resurrection principle. to be able to resurrect obsolete materials, it would be advisable to store the content with open-source software that can render it, an opensource operating system that can support the software, and separate plain-text instructions for how to reconstruct delivery. in addition, underlying assumptions of the storage device itself need to be made explicit if possible (type of file system partition, supported length of file names, character encodings, inode information locations, etc.). some of the need for this form of preservation may be diminished through such efforts as the planets timecapsule deposit.18 this consortium has gathered the supporting software and information necessary to access current common types of digital files (such as pdf), for long-term storage in swiss fort knox. one of the drawbacks to gathering and storing content developed for a tremendous amount of metadata collection. where the focus has been on what is the best metadata to collect, the question becomes: what is the minimal metadata and contextual information needed? the following is an attempt to begin this conversation in the hope that debate will clarify and distill the absolutely necessary and specific requirements to enable long-term access with the lowest possible barrier to implementation. if we consider the purpose of preservation to be solely that of ensuring long-term access, it is possible to selectively identify information for inclusion. the recent proposal by the researchers of the national geospatial digital archive (ngda) may help to direct our focus. they have defined three architectural design principles that are necessary to preserve content over time: the fallback principle, the relay principle, and the resurrection principle.13 in the event that the system itself is no longer functional, then a preservation system should support some form of hand-off of its content—the fallback principle. this can be met by involvement in lockss, as specified above. lacking the ability to support even this, current creators and hosts of digital content may be at the mercy of political or private support for ingest into trusted digital repositories.14 the recently developed bagit file package format includes valuable information to ensure uncorrupted transfer for incorporation into such an archive.15 each base directory containing digital files is considered a bag, and the contents can be any types of files in any organization or naming convention; the software tags the content (or payload) with checksums and manifest, and bundles it into a single archive file for transfer and storage. an easily usable tool to create these manifests has already been developed to assist underfunded cultural heritage organizations in preparing content for a hosting institution or government infrastructure willing to preserve the content.16 the gap of who would communications | deridder 73benign neglect: developing life rafts for digital content | deridder 73 clifford lynch pointed out, funding cutbacks at the sub-federal level are destroying access and preservation of government records; corporate records are winding up in the trash; news is lost daily; and personal and cultural heritage materials are disappearing as we speak.24 it is valuable and necessary to determine best practices and to seek to employ them to retain as much of the cultural and historical record as possible, and in an ideal world, these practices would be applied to all valuable digital content. but in the practical and largely resource-constrained world of most libraries and other cultural institutions, this is not feasible. the scale of content creation, the variety and geographic dispersal of materials, and the cost of preparation and support makes it impossible for this level of attention to be applied to the bulk of what must be saved. for our cultural memory from this period to survive, we need to communicate simple, clear, scalable, inexpensive options to digital holders and creators. references 1. planets consortium, planets preservation and long-term access through networked services, http:// www.planets-project.eu/ (accessed mar. 29,

hathitrust: a shared digital online delivery of cached derivatives and metadata, as well as webcrawlerenabled content to expand accessibility. this model of online delivery will enable low cost, scalable development of digital libraries by simply ordering content within the archival storage location. providing simple, clear, accessible methods of preparing content for preservation, of duplicating archival treasures in lockss, and of web accessibility without excessive cost or deep web database storage of content, will enable underfunded cultural heritage institutions to help ensure that their content will continue to survive the current preservation challenges. as david seaman pointed out, the more a digital item is used, the more it is copied and handled, the more it will be preserved.23 focusing on archival storage (via lockss) and accessibility of content fulfills the two most primary oais functional capabilities and provides a life raft option for those who are not currently able to surmount the forbidding tsunami of requirements being drafted as best practices for preservation. the importance of offering feasible options for the continued support of the long tail of digitized content cannot be overstated. while the heavily funded centers may be able to preserve much of the content under their purview, this is only a small fraction of the valuable digitized material currently facing dissolution in the black hole of our cultural memory. as while no programmers are needed to organize content into such a clear, consistent, and standardized order, we are developing scripts that will assist others who seek to follow this path. these scripts not only order the content, they also create lockss manifests at each level of the content, down to the collection level, so that the archived material is ready for lockss pickup. a standardized lockss plugin for this method is available. to assist in providing access without a storage database, we are also developing an open-source web delivery system (acumen),22 which dynamically collects content from this protected archival storage arrangement (or from webaccessible directories) and provides

professor, university of novi sad. danijela boberić krstićev (dboberic@uns.ac.rs) is associate professor, university of novi sad. abstract business intelligence (bi) refers to methodologies, analytical tools, and applications used for data analysis of business information. this article aims to illustrate an application of bi in libraries, as reporting modules in library management systems are usually inadequate for a comprehensive business analysis. the application of bi technology is presented as a case study of libraries using the bisis library management system in order to overcome shortcomings of an existing reporting module. both user requirements regarding reporting in bisis and already existing transactional databases are analysed during the development of a data warehouse model. based on that analysis, three data warehouse models have been proposed. also, examples of reports generated by an olap tool are given. by building the data warehouse and using olap tools, users of bisis can perform business analysis in a more user-friendly and interactive manner. they are not limited with predefined types of reports. librarians can easily generate customized reports tailored to the specific needs of the library. introduction organizations usually have a vast amount of data which increases on a daily basis. the success of an organization is directly related to its ability to provide relevant information in a timely manner. an organization must be able to transform raw data into valuable information that will enable better decision-making.1 for this reason, it is impossible to imagine an organization without an efficient reporting module as a part of its management information system. if we put libraries in a business context, they are very similar to any other organization. the common characteristic of each is that they have high demand for a variety of statistical reports in order to support their business. a library management system uses a transactional database to store and process relevant data. this database is designed in accordance with the main functionalities of the system. information used to make strategic decisions is usually obtained from historical and summarized data. however, the database model may have a complex structure and may not be suitable for performing analytical queries that are often very complex and involve aggregations. execution of those queries may be a time-consuming and resource-intensive process that can decrease performance as well as the availability of the system itself. also, creating such queries can require advanced it knowledge. these problems can be overcome by developing business intelligence systems. business intelligence (bi) refers to methodologies, analytical tools, and applications used for data analysis of business information. bi gives business managers and analysts the ability to conduct mailto:tesendic@uns.ac.rs mailto:dboberic@uns.ac.rs business intelligence in the service of libraries |tešendić and krstićev 99 https://doi.org/10.6017/ital.v38i4.10599 appropriate analyses. by analyzing historical and current data, decision-makers get valuable insights that enable them to make better, more-informed decisions. bi systems rely on a data warehouse as an information source. the data warehouse is a repository of data usually structured to be available in a form ready for analytical processing activities. 2 business intelligence systems do not exist as ready-made solutions for each organization, but need to be built in accordance with the characteristics of each organization using the appropriate methodology. this article proposes a data warehouse architecture and usage of olap tools in order to support bi in libraries. the application of bi technology is illustrated through a case study of libraries using the bisis library management system. the first step in implementation of bi was the creation of a data warehouse model considering data that exist in bisis and requirements regarding reporting. after the data warehouse model had been created, data were loaded into the data warehouse using olap tools. olap tools were also used for visualization of data stored in the data warehouse. reporting in bisis the bisis library management system has been in development since 1993 by the university of novi sad, serbia. currently, the bisis community comprises over forty medium-sized libraries in serbia.3 the primary modules of the bisis system include cataloguing, reporting, circulation, opac, bibliographic data interchange, and administration. bisis supports cataloguing according to unimarc and marc 21 formats using an xml editor for bibliographic material processing.4 the bisis search engine is implemented with a lucene engine.5 bisis supports z39.50 and sru protocols for the search and retrieval of bibliographic records.6 those protocols are also used for developing a bisis service for searching and downloading electronic materials by the audio library system for visually impaired people.7 in addition, bisis allows sharing of bibliographic records with the union catalogue of the university of novi sad.8 the circulation module features all standard activities for managing users: registration, charging, discharging, searching users and publications, and generating different kinds of reports, as well as user reminders.9 the reporting module of bisis is implemented using the jasperreports tool.10 however, this module has some limitations due to the fact that bisis works only with a transactional database and does not cope well with complex reports. firstly, in order to generate reports regarding library collections, it is necessary to process all bibliographic records stored in that transactional database. this activity significantly burdens the system and reduces its performance. to avoid this, reports are prepared in advance outside working hours, usually at night. consequently, those reports include only data collected before report generation. creating reports in this manner greatly reduces system load and speeds up presentation of the reports because they are already generated. however, some reports, such as those related to the financial aspects of the library (e.g., the number of new members and the balance at the end of the day), need to be created in real time. due to the execution in real time, those reports are ineffective and affect the performance of the entire system. the next limitation of this reporting module is that it has a set of predefined reports and the creation of new reports requires additional development. in the current deployment it is not possible to add new reports without engaging software developers. also, an additional obstacle is the fact that the data for generating reports are obtained from two different data sources (described in more detail in the following sections). for example, the report regarding the number information technology and libraries | december2019 100 of borrowed books by the udc (universal decimal classification) groups requires data about the udc groups from xml documents and data about book borrowing from the relational database. generating this kind of reports cannot be done in a timely and efficient manner. taking into account these shortcomings of the reporting module, it can be concluded that the application of business intelligence, primarily data warehouse and olap tools, could improve analytical data processing in the libraries using bisis. related work one of the basic components of the business intelligence system is a data warehouse. a data warehouse is a centralized database that stores historical data. those data are in principle unchangeable and they are obtained by collecting and processing data from various data sources. data warehouses are used as support for making business decisions.11 the data sources for a data warehouse can be diverse and may include transactional databases and different file formats. the process of integrating data from different data sources into a single database is called data warehousing. data warehousing includes extracting, transforming, and loading (etl) data into data warehouse.12 the goal of data warehousing is to extract useful data for further analysis from the huge amount of data that is potentially available. there are different approaches to modeling a data warehouse. these approaches can be classified in three different paradigms according to the origin of the information requirements: (1) supplydriven, (2) demand-driven, and (3) hybrids of these. a supply-driven approach is based on data that exist in the transactional database. these data are analyzed to determine which data are the most relevant for making business decisions, or which data should be part of the data warehouse. alternatively, a demand-driven approach is based on the end-user requirements which means that the data warehouse is modeled in a way that is possible to get answers to the questions asked by the users. the third approach is a hybrid approach and it combines the previous two approaches in the process of data warehouse modelling. the hybrid approach attempts to diminish the shortcomings of the previous two approaches. in the case of a supply-driven approach, the data warehouse will probably not meet the requirements of the end users, while in the demand-driven approach there may be no data to fill the created data warehouse. in an article published in 2009, romero and abelló gave an overall view of the research in the field of dimensional modeling of data warehouses.13 various examples of implementation of data-warehouse solutions in libraries can be found in the literature. in 2014, siguenza-guzman et al. described the design of a knowledge-based decision support system based on data-warehouse techniques that assists library managers making tactical decisions about the optimal use and leverage of their resources and services. when designing the data warehouse, the authors started from the requirements of the end users (demand -driven approach) and extracted data from heterogeneous sources.14 a similar approach has been used by yang and shieh, who started from the reports needed by public libraries in taiwan and through an iterative methodological approach modeled a data warehouse that meets all their reporting requirements.15 unlike the previously described articles where a demand-driven approach was used, we applied a hybrid approach to modeling data warehouse. we analyzed data sources that exist in bisis business intelligence in the service of libraries |tešendić and krstićev 101 https://doi.org/10.6017/ital.v38i4.10599 following a supply-driven approach, but we also analysed user requirements to identify the facts and dimensions for the dimensional data warehouse model. modeling the data warehouse in order to implement a data warehouse solution, the first step is to design a data model suitable for analytical data processing. a data warehouse usually stores data in a relational database and organizes them in so called dimensional models. unlike standard relational database models, those models are denormalized and provide easier data visualization. data can be presented as a cube with three, four or n-dimensions. analyzing such data is more intuitive and user-friendly. the dimensional model contains the following concepts: dimensions, facts, and measures. dimensions represent the parameters for data analysis while facts represent business entities, business transactions, or events that can be used in analyzing business processes. the most commonly used model in dimensional modeling is the star model. after identifying the facts and dimensions, a dimensional model almost always resembles a star, with one central fact and several dimensions that surround it. dimensions and facts are usually implemented as tables in the relational database. dimension tables contain primary keys and other attributes. fact tables contain numerical data as well as dimension tables keys. the measure is a numerical attribute of the fact table and can be obtained by aggregating data by certain dimensions. there are several approaches to modeling data warehouse and we followed a hybrid approach to design dimensional models presented in this article. this implies that both the existing data sources and the user requirements were considered while designing the final data-warehouse models. that modeling process involved the following activities: 1. analysis of existing data sources in bisis with identification of possible facts and dimensions, 2. analysis of user requirements regarding reporting, 3. refactoring of the facts and dimensions in accordance with the user requirements, and 4. design of dimensional models. analysis of data sources in bisis the first step in creating a data warehouse is an analysis of existing data sources. the bisis system uses two different data sources. bibliographic records are stored in xml documents, while circulation data, as well as holdings data regarding the items that are circulated, are stored in a relational database. in 2009, tešendić et al. described the bisis circulation database model.16 that model describes data about individual and corporate library members. data about members includes information about personal data, membership fees, as well as information about a member’s borrowed and returned items. bibliographic data in bisis are presented in unimarc format. dimić and surla in 2009 described the model for bibliographic records used in bisis.17 a bibliographic record is modeled as a list of fields and subfields. a field contains a name, values of the indicators and a list of subfields. a subfield contains a name and a value of that subfield. the data described by that model are stored in xml documents because the bibliographic record structure is not suitable for relational modeling. that structure is more in line with the document-oriented data storage approach. information technology and libraries | december2019 102 analysis of user requirements one of the essential functionalities of information systems, including library management systems, is to provide various statistical reports that should help the management of the library to make better business decisions. user requirements related to analytical processing in bisis can be grouped into several categories. the first category consists of requirements regarding reports on the library collections. examples of reports from this category are: • number of publications per language for a certain period of time; • number of publications by departments; • number of new publications for a certain period of time; and • number of publications by udc groups. the second category consists of requirements related to the circulation of library resources. examples of such reports are: • number of borrowed items by member category; • number of borrowed items by language of publication; • number of borrowed items by departments; • the most popular books; and • the most avid readers for a certain period. the third category consists of requirements related to the reports on financial elements of the library's business. some of the reports are: • number of new members on a daily basis with a financial balance; • number of members by membership category and gender; and • number of members per departments. analyzing user requirements, it was perceived that a new data warehouse have to be created using data from both data sources. this means that appropriate transformations of data from the relational database as well as from the bibliographic records documents need to be performed. data warehouse models taking into account the reporting requirements as well as the data that exist in bisis, appropriate dimensional models are designed. the proposed dimensional models were designed to meet all the needs for analytical processing, as well as to enable flexibility of the reporting process in bisis. for each of the observed groups of reports, a dimensional model was created as described below. model describing library collection data a dimensional model of the bisis data warehouse used for analytical processing of the library collection data is shown in figure 1. the data from this model are used to generate reports on the library collection. examples of such reports are accessions register, number of items by udc group, number of items by departments, etc. in generating all these reports, an acquisition number of an item has the main role and all reports are created either by counting the acquisition numbers or by displaying the acquisition business intelligence in the service of libraries |tešendić and krstićev 103 https://doi.org/10.6017/ital.v38i4.10599 numbers along with other data related to that item. therefore, the acquisition number represents the measure in this dimensional model. the central table in the model is the item table and it presents a fact table. this table contains the acquisition number and foreign keys from dimension tables. all other tables in the model are dimension tables. the publication table represents a dimension table containing bibliographic data from bibliographic records. only data that are needed for reports are extracted from bibliographic records and stored in this table. those data refer to the name of the author, the title of the publication, the publication’s isbn and udc number, the number of pages, keywords, and an identification number for the bibliographic record in the transactional database. the acquisition table represents a dimension that describes the publication's acquisition data such as a retail price, the name of the supplier, and the invoice number. the location table describes departments within the library where an item is stored. the status, publisher, language, and udc_group tables relate to information about the status of an item, publisher, language of the publication, and udc group to which an item belongs. the date and year tables represent the time dimensions. data in the date table are extracted from the date of an item acquisition and data in the year table are extracted from the publishing year. figure 1. dimensional model describing library collection data. information technology and libraries | december2019 104 model describing library circulation data a dimensional model of the bisis data warehouse used for the analytical processing of library circulation data is shown in figure 2. data from this model are used for generating statistical reports regarding usage of library resources. examples of such reports are the number of borrowed publications according to different criteria (such as user categories, language of publication, departmental affiliation of the user who borrowed the publication, etc.). these data can answer questions about the most popular books or the readers with the highest number of borrowed books. similar to the previous reporting group, the acquisition number of the item which was borrowed has the main role in generating those reports. all reports from this group are created by counting acquisition numbers of borrowed items and displaying data related to those checkouts. therefore, in this dimensional model, the acquisition number is a measure. the central table in the model is the lending table and is presented as a fact table. this table contains the acquisition number of the borrowed item and foreign keys from the dimension tables. all other tables in the model are dimension tables. the publication, publisher, year, acquisition, ucd_group, status, and language tables contain data from bibliographic records and the content of these tables have been already explained. the member, membershiptype, category, education, and gender tables represent the dimension tables containing information about library users. these data are only a subset of circulation data from transactional database. the location table describes departments within the library where items are borrowed. the date table represents the time dimension. the data in the date table are derived from the date of borrowing and the date of discharge of an item. business intelligence in the service of libraries |tešendić and krstićev 105 https://doi.org/10.6017/ital.v38i4.10599 figure 2. dimensional model describing library circulation data. model describing members’ data a dimensional model of the bisis data warehouse used for the analytical processing of members’ data is shown in figure 3. data from this model are used for generating statistical reports on library members, as well as for generating financial reports based on membership fees. examples of such reports are the number of members according to different criteria (such as department of registration, member category, type of membership, gender, or education level). also, this report group contains reports that include a financial balance (for example, a list of members with membership fees in a certain time period). the membership fee has the main role in generating these reports. all reports from this group are generated by counting or displaying members who have paid a membership fee or summarizing membership fees. therefore, in this dimensional model, membership fee is a measure. the main table in the model is the membership table and it presents a fact table. it contains the membership fee, which is the measure, and foreign keys from the dimension tables. information technology and libraries | december2019 106 all other tables in the model are dimension tables. tables member, membershiptype, category, education and gender represents the dimension tables that contain information about library members and the content of these tables was previously described. the table location describes departments within the library where user registration is performed. the table date represents the time dimension. data in the table date are based on the registration date and the date of the membership expiration. figure 3. dimensional model describing library members. true value of a data warehouse in the previous sections, we presented models of data warehouse, but those models are unusable if they are not implemented and populated with data needed for business analysis. extracting, transforming, and loading (etl) processes are responsible for reshaping the relevant data from the source systems into useful data to be stored in the data warehouse. etl processes load data into a data warehouse, but that data warehouse is still only storage for those data. a real-time and interactive visualisation of those data will show the true benefits of data warehouse implementation in various organisations including libraries. to load as well as to analyze and visualize large volumes of data in data warehouses, various online analytical processing (olap) tools can be used.18 the usage of olap tools does not business intelligence in the service of libraries |tešendić and krstićev 107 https://doi.org/10.6017/ital.v38i4.10599 require a lot of programming knowledge in comparison to tools used for querying transactional databases. the interface of olap tools should provide a user with a comfortable working environment to perform analytical operations and to visualize query results without knowing programming techniques or structure of transactional database. there are various olap tools available on the market.19 when choosing an olap tool to be used in an organization, there are several important criteria to consider: the duration of query execution, user-oriented interface, the possibility of interactive reports, price of tool, automation of the etl process, etc.20pentaho bi system is one of the open-source olap tools which satisfies most of those criteria. among various features, pentaho supports creation of etl processes, data analysis, and reporting.21 implementation of etl processes can be a challenging task primarily because of the nature of the source systems. we used pentaho tool to transform data from bisis to the data warehouse, as well as to visualize data and generate statistical reports. etl processes modeling after creating a data-warehouse model, it is necessary to load data into the data warehouse. the first step in that process is to extract data from the data sources. those data may not be in accordance with the newly created data-warehouse model and appropriate transformations of data may be needed before loading. regarding the structure of the data sources, transformations can be implemented from scratch, or by using dedicated olap tools. both techniques are used in the development of our data warehouse. transformations that required data from bibliographic records were implemented from scratch because of complex data structure, while transformations that processed data from relational database are implemented using pentaho data integration (pdi) tool. pdi is a graphical tool that enables designing and testing etl processes without writing programming code. figures 4 and 5 show an example of transformations created and executed by that tool. those transformations have been applied to load members’ data from bisis relational database into the data warehouse. figure 4. transformations for loading members data. information technology and libraries | december2019 108 figure 5. the membershiptransformation process. an issue that may arise after an initial loading of a data warehouse relates to updating the data warehouse. in order to achieve a better performance of transactional databases, updates of the data warehouse should not be performed in real time. in the case of library management systems, those updates can be performed outside of working hours so data in the data warehouse will be up to date on a daily basis. an update algorithm can be defined as an etl process using olap tools or it can be implemented from scratch. data visualization the basic task of olap tools is to enable visualization of data stored in a data warehouse. the olap tools use multidimensional data representation, known as a cube, which allows a user to analyze data from different perspectives. olap cubes are built on dimensional models of a data warehouse and consist of dimensions and measures. dimensions form the cube structure and each cell of the cube holds a measure. measures are derived from the records in the fact table and dimensions are derived from the dimension tables. olap tools allow a user to select a part of the olap cube by setting an appropriate query and that part can be further analyzed by different dimensions. this process is performed by applying common operations on the cube which include slice and dice, drill down, roll up, and pivot.22 data that are results of operations on the cube can be visualized in the form of tables, charts, graphs, maps, etc. the main advantage of olap tools reflects is that end users can do their own analyses and reporting very efficiently. users can extract and view data from different points of view on demand. olap tools are valuable because they provide an easy way to analyze data using various graphical wizards. by analyzing data interactively, users are provided with feedback which can define the direction of further analysis. in order to visualize data from our data warehouse, we used the pentaho olap tool. we used it to create predefined reports identified during the analysis of user requirements as well as some interactive reports using operations on the olap cube. examples of generated reports are presented below in order to illustrate some features of the pentaho olap tool. an example of a report shown in figure 6 was obtained with a dice operation on the cube. the dice operation selects two or more dimensions from a given cube and provides a new sub-cube. in this particular example, we selected three dimensions: gender, member category, and registration date. business intelligence in the service of libraries |tešendić and krstićev 109 https://doi.org/10.6017/ital.v38i4.10599 figure 6. example of dice operation performed on the olap cube. information technology and libraries | december2019 110 figure 7. example of roll-up and drill-down operations performed on the olap cube. business intelligence in the service of libraries |tešendić and krstićev 111 https://doi.org/10.6017/ital.v38i4.10599 additionally, we analyzed only those data from 2014 to 2018. the result of this operation is presented in the form of nested pie charts. however, other forms of visualisation can be applied on the same data set very easily. in figure 7, a more complex report is presented. that report is obtained by performing combination of roll-up and drill-down operations. the roll-up operation performs aggregation on a cube reducing the dimensions. in our example, we aggregated the number of newly acquired publications for certain years ignoring all other dimension except the date dimension. a user can select a particular year, quarter, and month and analyze details of purchased publications in that period, such as title and author of the publication. this is an example of using drill-down operation on the cube. the result of that operation is presented as a table, as shown in figure 7. this report is interactive, because user can investigate data in more detail by performing other operations on the cube that are placed on the toolbar of the report. conclusion this article aims to illustrate an application of business intelligence in libraries, as reporting modules in library management systems are usually inadequate for a comprehensive business analysis. development of a data warehouse, which is the base of any business intelligence system, as well as usage of olap tools are presented. both user requirements regarding reporting in bisis and already-existing transactional databases are analyzed during the development of a datawarehouse model. based on that analysis, three data-warehouse models have been proposed. also, examples of reports generated by an olap tool are given. by building the data warehouse and using olap tools, users of bisis can perform business analysis in a more user-friendly manner than with other processes. users are not limited to predefined types of reports. librarians can easily generate customized reports tailored to the specific needs of the library. in this way, librarians work in a more comfortable environments, performing analytical operations interactively and visualizing query results without additional programming knowledge. the article presents the usage of pentaho olap tool, but the proposed data-warehouse model is independent of olap tools selection and any other tool can be integrated with the proposed data warehouse. references 1 ralph stair and george reynolds, fundamentals of information systems (cengage learning, 2017). 2 ramesh sharda, dursun delen, and efraim turban, business intelligence,

dodsworth and andrew nicholson academic uses of google earth and google maps in a library setting | dodsworth and nicholson 102 abstract over the last several years, google earth and google maps have been adopted by many academic institutions as academic research and mapping tools. the authors were interested in discovering how popular the google mapping products are in the academic library setting. a survey was conducted to establish the mapping products’ popularity, and type of use in an academic library setting. results show that over 90 percent of the respondents use google earth and google maps either to help answer research questions, to create and access finding aids, for instructional purposes or for promotion and marketing. the authors recommend expanding the mapping products’ user base to include all reference and liaison librarians. introduction since their launch in 2005, google maps and google earth have had an enormous impact on the way people think, learn, and work with geographic information. with easy access to spatial and cultural information, google maps/earth has provided users with the means to understand their world and their communities of interest. moreover, the customizable map features and dynamic presentation tools found in google maps and google earth make each one an attractive option for someone wanting to teach geographic information or make customized maps. for academic researchers, google mapping applications are also appealing for their powerful ability to share and host projects, create customized kml (keyhole markup language) files, and to easily communicate their own research findings in a geographic context. recognizing their potential for revitalizing map collections and geographic education, the authors felt that many academic libraries were also going to be active in using google maps/earth for a variety of purposes, from promoting their services to developing their own google kml files for users. with google earth’s ease of use and visualization capabilities, it was even thought that academic libraries would be using google earth heavily in instruction classes bringing geographic information to subject areas traditionally outside of geography. as active users of google maps/earth in their roles as academic librarians at their universities, the authors became curious to know what other academic librarians were doing with google maps/earth, particularly those working with maps and/or geography subjects. were they using eva dodsworth (edodsworth@uwaterloo.ca) is geospatial data services librarian, university of waterloo library, waterloo, and andrew nicholson (andrew.nicholson@utoronto.ca) is gis/data librarian, hazel mccallion academic learning centre, university of toronto mississauga, ontario mailto:edodsworth@uwaterloo.ca mailto:andrew.nicholson@utoronto.ca information technology and libraries | june 2012 103 the technology as part of their librarian roles on campus? how were they using it? what impacts was it having in how they delivered library services? to help answer these questions, the authors set out on a three-stage process with the aim of providing a more complete picture of google maps/earth use in academic libraries. the first stage consisted of a literature search focusing on library and information science research databases, to see what (if any) scholarly research had been written that discussed the role of google maps/earth in academic libraries. the second stage of the research had the authors examining over a dozen academic library websites to assess how they were integrating google maps/earth either through an api plug-in on their website or advertising other google maps/earth related services and collections. the third stage had the authors compile a set of twenty survey questions which were then distributed to academic librarians across canada and the united states, probing the use of google mapping products in the academic library setting. literature review despite the ubiquity of google for information searching, there was a surprising paucity of literature that documents the impact of google maps/earth in academic libraries. nevertheless, there are some articles which indicate just how much google maps can help raise the profile of library services. terry ballard, a librarian at quinnipiac university, describes in a few articles how he and colleagues were able to use google earth placemarks to promote his library’s special collections.1 the potential for “discovering the library with google earth” is also a theme in an article by brenner and klein in which the portland state university library linked their urban planning documents collection to google earth for ease of searching.2 although the focus is on public libraries, michael vandenburg documents how his library system began “using google maps as an interface for the library catalogue.” in his article, vandenburg discusses that the inspiration for such a project came about through various google maps mashups that were popular on search oriented websites such as “housing maps,” which combined realtor listings from craigslist with a google maps api. using api coding, vandenburg was able to link latitude and longitude data of countries to individual opac records enabling a visual search for items at the country level.3 while these articles focused on use of google earth as a collection discovery tool, troy swanson notes the visualization aspects of the applications and their utility for teaching information literacy. swanson has students use google earth and second life as tools to create a virtual exhibit on malcolm x. although swanson notes that the final output by the students did not meet the initial expectations, valuable learning opportunities for teaching in a 3d space were recognized and should be pursued. 4 some of these opportunities are highlighted as case studies by lamb, noting the visualization aspects of google earth would be very useful for librarians providing instruction.5 academic uses of google earth and google maps in a library setting | dodsworth and nicholson 104 google maps/earth & academic libraries: a scan of selected library websites for the next stage, the authors performed an environmental scan of academic library websites to see how they are using and implementing google mapping technology into their services. many are doing creative and innovative project work which will, we hope, encourage and guide other libraries to consider doing something similar. mapping technology can be used in several different ways, and with internet users becoming more proficient using this technology, libraries have the opportunity to take advantage of this communication medium. any document or image that has a geographic component can be digitized and made easily accessible using online mapping technology. the following section will review some of the projects highlighted on websites. the projects can be grouped into the following categories: finding aids, collection distribution, and teaching and reference services. finding aids all collections in libraries require some sort of finding aid to locate library material—the most obvious one being the library catalog. however, there are many location-based materials that use customized finding aids such as map and air photo indexes, and geospatial data coverage maps. for several years now libraries have been trying to make access to the finding aids easier by digitizing them and offering them online. not only are online versions easily updatable, but they are quite often created using google technology, allowing for the use of modern basemaps and zoom capabilities. traditional paper indexes can be difficult to navigate, especially the historical ones, making the search process rather difficult for users and library staff. one of the most popular types of online indexes created by libraries is air photo indexes. most map libraries collect air photos, and many use similar indexes to help locate aerial photography for an area of interest. several libraries have digitized the indexes making the same information available online. users simply zoom into a geographical area and click on a point to retrieve the photo information they need in order to locate the air photo in the library collection. some libraries will even send an electronic copy of the photo to the users. the mcgill university library, for example, has made its air photo information available from their webpage in a kml format to be viewed in google earth. users can click on a point of interest to easily obtain the air photo information. mcgill library has also digitized topographic indexes, making them also available via google earth.6 the university of western ontario’s serge a. sauer’s library also provides its air photo indexes online, incorporating google maps directly into their website. placemarks representing individual photos have been inserted on a google map, along with the photo description so that when users click on the placemark, photo information is released. using google mapping technology to offer online finding aids that are searchable by location is an innovative and cost-free step towards collection accessibility. what would make these types of library collections even more accessible, however, is offering users online access to digital versions of the collection items themselves. so to bring the indexing project one step forward, not only would the photo reference information be made available, but the actual image would be too, information technology and libraries | june 2012 105 thereby allowing libraries to use google mapping technology as an avenue for collection distribution and delivery. collection delivery libraries have had digital collections for quite some time. many of course do not need to digitize resources themselves as they subscribe to products such as electronic journals and books. however there are still some less common collections that are physically housed in libraries that would be much more accessible to users if they were exposed and made available online. an internet search has shed light on numerous digitization projects that use google mapping technology to search for and deliver location-based collections. examples of these types of collections include historical maps and air photos, archived photos and postcards, audio interviews, community information, textual documents like letters and diaries, and gis data. mcmaster university library is one example of a library that has digitized a historical map collection and made it available online. an index to its world war i military maps and aerial photography was created using google maps, and was embedded into its webpage.7 users can click on an area of interest to bring up the corresponding high resolution map image. likewise, brock university library has also offered its historical air photo collection online, allowing users to search using a google map, and then download photos of interest.8 additionally, yale university library has created kml indexes of its fire insurance plans, with direct links to the digitized images.9 the university of connecticut library has digitized its local historical maps and using google maps had created a map mashup which includes historic landmarks. clicking on the landmarks provides users with links to related resources. several libraries have digitized other imagery, such as postcards and photography. this is particularly popular with archival and specialized collections. the university of vermont library has embedded a google map into its website with placemarks that when clicked lead the user to the library’s long trail collection, an assortment of over 900 images of the oldest long-distance hiking trail in the united states. the images have been digitized from hand-colored lantern slides.10 cleveland state university library has also done something similar with its cleveland memory project, in which google maps were embedded into the library webpage and placemarks of local historic landmarks added. when users click on the placemarks, they are able to access a description of the landmark along with a photograph of it. clicking on “more information” will lead the user to several related resources, including the library catalog, where original documents about the location are available (e.g., images, books).11 besides digitizing their collections, some libraries have also georeferenced them so that they could not only be accurately located using an index, but so that they could be viewed in google earth (kml format). offering collections in kml format greatly increases exposure and use of geographic resources because google earth is one of the more popular location-based applications used by library users and the public. geographic files such as georeferenced air photos and satellite images, as well as gis data used to be only viewed in specialized gis programs. but gis technology has evolved into so many online applications, offering all computer users the benefits of geographic information and a platform to distribute information. academic uses of google earth and google maps in a library setting | dodsworth and nicholson 106 the university of waterloo map library is one example of a library that had digitized its historical air photo collection and made the images available in kml format for google earth usage.12 users can access a map index of the available photos from the map library webpage and then click on the index to download the images. the university of north carolina library has georeferenced several historical maps and made them available for viewing as an image overlay in google maps. this particular mapping project consists of around 150 thematic maps, including historical soil surveys, road and highway maps, city/county maps, and more. users can take advantage of the georeferenced maps and accurately compare historical features to modern ones with google maps’ basemap. having a preview of the dataset before it is downloaded assists the user in downloading only what is needed.13 perhaps more popular than a library’s air photo collection are libraries’ collections of geospatial data. geospatial, or gis data, has traditionally been only used by users who have access to gis programs such as esri’s arcgis, or arcview. more recently, librarians have discovered that when spatial files are converted into easy-to use file formats, such as kml, the user group is broadened and the files are used more. so it is no surprise that several libraries have converted their gis shapefiles (a spatial data file format used specifically in gis programs) into kml files and made them available for download from their webpages. university of connecticut library offers its gis files online in various formats, including kml. it also provides a sample image of the gis layer in google maps.14 baruch college at the city university of new york has made neighborhood census data available in google maps. the geographic boundary files were overlaid in google maps, and clicking on the map will lead users to the files available from the american census bureau’s fact finder. clearly, many libraries have incorporated google mapping technology into their digitization projects. the technology has proven capable of attracting collections that are not strictly locationfocused such as maps and air photos, but that have a location associated with it, such as archival photos of community landmarks or books written about a specific locale. google mapping technology makes the organization and storage of collections relatively effortless for library project managers, and it makes collection searching and distribution simple and friendly for the users. other uses of google maps/earth in libraries perhaps one of the simplest uses of google mapping technology can be illustrated by visiting several library websites. many libraries have embedded google maps into their website as either a webpage header15 survey: what are academic library staff doing with google maps/earth?16 following the review of the literature and academic library websites, the authors wanted to discover how academic librarians themselves were using google maps and google earth in their work, if at all. to capture this data, the authors compiled a set of survey questions targeting those in the academic library community who work with maps, gis, or geography/geology/earth science subject matter. information technology and libraries | june 2012 107 in preparing the survey questions, the authors were aware of a “survey fatigue” among the academic library community. at the time of research, many surveys were going out to librarians requesting their time and responses, so the authors wanted to keep the survey concise both in terms of number of questions, but also in the types of questions. in the end, the survey was created with twenty questions consisting of six yes/no questions, seven multiple choice, and the remaining seven questions being short answer. for distributing the survey, the authors wanted to reach as many librarians who worked with maps, geospatial data and government document subject matter as possible. the survey was then distributed on specialized map library and government publication listservs, including maps-l, govinfo, gis4lib, and carta (canadian maps & air photo systems forum). the survey was also distributed on the members’ only lists belonging to the association of canadian map libraries & archives (acmla) and the western association of map libraries (waml) listservs. the survey was made available on survey monkey for two months from december 2010 to the end of january 2011. the responses with the survey available during a quieter period of library activities, and thanks to a couple of reminder emails being sent out on the lists, our questionnaire received a total of 83 responses. who is using google maps/earth? the first couple questions dealt with the department or area of the library in which the respondent worked in, and what their position encompassed. as expected, a large majority of respondents, 81 percent, worked in “map/gis services” while 28.8 percent also had “general reference” responsibilities. other library service areas mentioned included “data services” and “it,” as well as some that fell outside library boundaries where staff worked in geography and environment science departments. not surprisingly, 52 percent of the responses indicated that their position was “librarian,” with the majority being “gis librarian” or “map librarian.” others included “reference & instructional services librarian” and “science librarian.” also received were 17 responses from gis specialists, library technicians and map assistants. what was especially noteworthy was that 12 responses were from library administrators, directors, or department heads who were finding time to work with google earth as part of their responsibilities. this number also included gis coordinators and map curators responsible for making decisions in their departments. google mapping products : what is being used, how often and for what purpose? to gain an understanding of how library staff are using google mapping products, a series of questions was asked of the respondents to determine which products were being used, how often and for which tasks. respondents were given a list of all the google mapping products available, and were asked to indicate which ones they had worked with. not surprisingly, the top two products used by respondents were google maps, 93 percent (71) and google earth, 91 percent (69). google maps api had been used by 40 percent (30) of the respondents, followed by google earth pro at 38 percent (29). eight percent (6) had also worked with google earth api, and 7 percent (5) had used google earth plus. interestingly, one respondent indicated that they had deployed google earth enterprise in their library. academic uses of google earth and google maps in a library setting | dodsworth and nicholson 108 figure 1. respondents’ use of google mapping products since many of these users may have simply used the products occasionally, it was important to get a sense of how often the products were being used. when asked the question “how regularly do you work with google mapping products for work-related projects?” 69 percent (54) responded that they use the products at least once a month. of those responses, 45 percent (35) use them at least weekly. specifically, eighteen percent (14) use them one to two times a week, thirteen percent (10) use them three to four times a week, and fourteen percent (11) use them even more often than that. only six percent (5) responded that they don’t use the products at all. information technology and libraries | june 2012 109 figure 2. frequency of use for work-related projects as google maps/earth can be used in many different ways and for different purposes in a library environment, the survey inquired how in fact these products were being used in their libraries. the survey question listed four possible tasks that the technology could be used for with the additional option for respondents to enter their own ‘other’ usages. respondents could check off all that applied. the options given included: • instruction • promotion/marketing • answering research questions • creating/accessing a finding aid tool (air photo map indexes, etc.) • other: (fill in answer) the majority of respondents, 82 percent (58) indicated they were using the products to answer research questions; 61 percent (43) for creating or accessing a finding aid tool; 56 percent (40) for instruction purposes; 27 percent for promotion/marketing and 20 percent (14) have used them for “other” purposes including georeferencing imagery, for use in webpages or creating learning objects. academic uses of google earth and google maps in a library setting | dodsworth and nicholson 110 figure 3. level and frequency of use in instruction are google mapping products being used for library instruction? for the authors, one of the best aspects of google maps/earth applications is their visualization capabilities. the ability to easily create and display geographic information to engage students makes google mapping applications an ideal instruction tool. in many ways, google maps and google earth have helped promote map and spatial literacy as concepts that are teachable. despite the free availability and ease of use of google mapping applications, the authors were somewhat surprised from the survey to find that 72 percent of library staff surveyed noted that their institution did not have any kind of map, spatial, or geospatial literacy policy in place. when it came time to provide instruction in the classroom, the survey found that only 31 percent (26) of the respondents had even used google earth in a classroom. nevertheless, in looking at the course levels, library instruction with google earth tools is actually occurring at all levels, from first year to graduate. significantly however, the frequency of the instruction seems to peak in the fourth year, where staff are using in upwards of six to nine courses. respondents were asked to give some details of these sessions, and they included a variety of class topics from environmental awareness education for first year students, to learning digitization skills in later years. has your library taken advantage of google map/earth technology for promotion or marketing purposes? information technology and libraries | june 2012 111 from our environmental scan of library websites we saw many interesting uses of google maps and google earth that were embedded directly into websites. perhaps because of this the authors were surprised to find that 55 percent of the survey respondents did not believe their library was using these technologies for promotion or marketing purposes. for those respondents who were using google maps or google earth to boost services for users, quite a few provided interesting examples of what this technology can offer. many were using google map apis to enhance map and aerial photo indexes, creating greater awareness of these resources and enhancing access. one respondent noted they had created a campus tour that highlighted all of the buildings that made up the library system, while others were using google api technology to showcase particular digitization projects such as folklore collections or geologic atlases. when asked if such activities have helped to enhance services or provided benefits to users, many responded that they had for both the users and for other library staff. greater speed and an increased familiarity of the collections were cited by several respondents, who no longer need to consult the paper indexes. does the library provide support to the wider campus community using google mapping products (not including instructional collaborations)? although many libraries are now using google maps and google earth technology, the authors were surprised that many were not actively leveraging this expertise across their campuses. almost all the respondents either skipped the question or stated that they were not providing this kind of active support. several noted that their gis services were open to all and that they were responsible for the google earth pro licences on campus, but that this was the extent of their support. working with google map/earth (kml) files in the last few years, kml files have become one of the more popular ways to display and distribute geographic information online. with its ease of use, and access, kml files have considerably broadened the user base of geographic information. kml files can be easily created in google earth, and they can be easily converted from gis files in specialized programs. it is this ease of access and usability that has popularized geographic information, hence increasing exposure to library collections and services. this survey was therefore interested in determining how libraries are using and creating kml files. when survey respondents were asked whether they work with kml files, 64 percent (47) responded they did, with 85 percent (40) claiming that they create their own kml files. for those who create their own, 92 percent (34) said that they created kml files by converting them from another file format using an external application, such as arcgis, earthpoint, ogr20gr, or shp2kml software. 78 percent (29) also created them in google earth, and 32 percent (12) created kml files by writing their own xml code. the authors were most interested to know if kml files were actually held as part of the library holdings. thirty percent (13) of respondents noted that they provide access to their kml files as academic uses of google earth and google maps in a library setting | dodsworth and nicholson 112 part of their collections, with 89 percent, (8) claiming they could be located through the library website. other areas mentioned for access included libguides and specialized gis data catalogues available through the library’s website. in terms of quantity, one respondent claimed a collection of 500-800 kml files, while other responses mentioned amounts in the ranges from 5 to 100, with some claiming that they were not sure exactly how many made up their collection. what other online mapping tools are used in your library apart from google maps and google earth? although google maps and google earth are perhaps the most well-known online mapping tools available, the authors were also interested to learn if there were other products that libraries were using as part of their service offerings. as expected many mentioned esri’s arcgis online and esri’s arcexplorer, while other responses included bing maps, openstreetmap, and open layers. discussion google mapping applications are clearly being used for academic purposes in library settings. with such diverse capabilities made available in these programs, library professionals are using them in several different ways. google earth and google maps are popular among library staff who work with gis and/or map collections. in fact, over 90 percent of the respondents use both products, either to help answer research questions, to create and access finding aids, for instructional purposes or for promotion and marketing. google mapping products have also helped libraries revitalize their collections as well as assist in transferring spatial information literacy skills to academic students and faculty. the authors hope that readers who work in a map/gis library setting will be inspired by the many examples of online mapping projects outlined in this paper and they will too use the online tools to the benefit of their library and their library users. google mapping products offer libraries an online platform to share information, and resources in an easy, accessible and low-cost way. the survey results also indicate that map/gis professionals in academic libraries trust and rely on google maps/earth as a solution to many academic queries and needs. since google mapping products were created for the use by mainstream society, it can be suggested that all other nonmap and gis related fields may find the products to be beneficial and useful to them as well. google earth and google maps are very easy to learn and the users do not require any spatial or mapping skills. as this survey was limited to map/gis users, the authors do not know how, if at all, google mapping products are being used by other library staff. this will be a future area of study. the authors do strongly suggest however for map/gis librarians to consider offering training sessions to reference staff and liaison librarians. as a multidisciplinary tool, many subject areas can benefit from google maps/earth, as it’s certainly not a tool for use by only gis/map librarians. with a little bit of training, all library staff can use google mapping products to assist with research questions, spatial literacy, location-based projects and library instruction. in fact, library staff members responsible for nontraditional library material such as photographs, postcards, audio recordings, original hand-written documents, etc. may want to consider using online mapping products to organize their collection. too many times such original material is lost in the library’s filing system, is irretrievable or unavailable during convenient hours. google maps/earth will organize all collections based on their geographic location and can offer access to the actual information technology and libraries | june 2012 113 material. more exposure to and training on these free and easy to use products can increase collection use, promote mapping technology, and organize the library’s holdings. references 1 terry ballard, “inheriting the earth: using kml files to add placemarks relating to the library’s original content to

joiner information technology and libraries | september 2018 5 ida a. joiner (ida.joiner@gmail.com), a member of lita and the ital editorial board, is the librarian at the universal academy school in irving, texas. she is the author of “emerging library technologies: it’s not just for geeks” (elsevier, august 2018). have you ever wanted to implement new technologies in your library or resource center such as (drones, robotics, artificial intelligence, augmented/virtual reality/mixed reality, 3d printing, wearable technology, and others) and presented your suggestions to your stakeholders (board members, directors, managers, and other decision makers) only to be rejected based on “there isn’t enough money in the budget,” or “no one is going to use the technology,” or “we like things the way that they are,” then this column is for you. i am very passionate about emerging technologies, how they are and will be used in libraries/ resource centers, and how librarians will be able to assist those who will be affected by these technologies. i recently published a book introducing emerging technologies in libraries. i came up with suggestions on how doing your research — including the questions below and those on the accompanying checklist —will prepare you to meet with your stakeholders and improve the likelihood of your emerging technology proposal being approved. 1. who are your stakeholders and include them early on in the process? determine who you stakeholders are, what their areas of expertise are, and how they can support your emerging technology projects. the most critical piece to getting your stakeholders on board to support your technology initiatives is addressing the question “what’s in it for them?” this will get their attention and increase your odds to getting to say “yes” to your technology initiatives. 2. what are the costs? research what your costs will be and create a budget. find innovative ways to fund your initiatives by researching grants, strategic partnerships with others who might be interested in partnering with you, and locating other funding opportunities. 3. what are the risks? identify any potential risks so that you are prepared to discuss how you will mitigate them when you meet with your stakeholders. some potential risks that you might want to address are budget cost overruns or staffing issues such as a key person resigning or going on maternity or sick leave, or policies in place to deter patrons from trying to use the technology for criminal means. mailto:ida.joiner@gmail.com

https://doi.org/10.6017/ital.v37i3.10746 4. what is the timeline and key milestones? address the timeline for when you want or need to implement these technologies? have you planned for key milestones and possible delays such as funds not being available? you need to have a detailed timeline, from your first kickoff meeting with your initiative’s team, to your stakeholder meeting where you present your proposal, to getting signoff on the project. 5. what training will you offer? perform a needs assessment to determine who will need to be trained, what training you will offer, what your training costs will be, and who will pay for them. once you have all of this in place, you will select the trainer(s) and the training model (such as “train the trainer”) that you will use. 6. how will you market your technology initiatives? will you rely on social media to market your technology initiatives? will you collaborate with your marketing department for developing your message through press releases, websites, blogs, e-newsletters, flyers, and other media outlets? you will need to meet with your marketing and publications experts to plan how you will market your emerging technology initiatives along with your costs and who will pay them. 7. who is your audience and how can you engage them? this is the one of the most important areas to address in your proposal to present to your stakeholders. without our patrons, there is no library. you will need to determine who your audience is and how you can utilize the emerging technologies to assist them. are they k to 12 students, adults who will be displaced by these technologies, technology novices who want to learn more about these technologies, or university faculty and/or students who want to use the technology for their projects? you can address all of these potential audiences in your proposal to your stakeholders. these are just a few tips on how to get stakeholder buy-in for implementing emerging technologies in your library. feel free to share some of your own successes in getting shareholders on board to implement emerging technologies in your library or resource center. information technology and libraries | septmeber 2018 7 emerging technology stakeholder buy-in questionnaire i have included questions below that you should follow when you are considering getting your stakeholders on board to implement new emerging technologies in your library. if you address all of these, you have a very good chance of getting your stakeholders on board to support your initiatives. 1. what technologies do you want to implement in your library/resource center and why do you want them? 2. who are your stakeholders and what are their backgrounds? 3. why should your stakeholders support your technology initiatives? 4. what is your budget for your new technology initiatives? 5. what training is needed to support these initiatives, who will provide the training, what are the costs, and who will pay for the training? 6. how will you market these technology initiatives, what are the costs, and who will pay for them? 7. did you perform a cost-benefit-analysis for these technology initiatives? 8. are there legal fees? if so, what are they, and who will pay for them? 9. what are the risks? 10. what are the returns on the investment (roi)? 11. what strategic partnerships can you establish? 12. what is your timeline for implementing these technology initiatives? emerging technology stakeholder buy-in questionnaire letter from the editor kenneth j. varnum information technology and libraries | december 2018 1 https://doi.org/10.6017/ital.v37i4.10852 as 2018 draws to a close, so does our celebration of information technology and libraries’ 50th anniversary. in the final “ital at 50” column, editorial board member steven bowers takes a look at the 1990s. much as for steven, for me this decade was where my career direction and interests crystallized around the then-newfangled “world wide web.” taking a look at the topics covered in ital over those ten years, it’s clear that plus ça change, plus c'est la même chose: the more things change, the more they stay the same. we were exploring then questions of how the burgeoning internet would allow libraries to provide new services and be more efficient and helpful in improving existing ones. user experience, distributed data and the challenges that causes, who has access to technology and who does not…. all topics as vibrant and concerning then as they ar e now. with the end of our look back at the last 50 years, we are taking the opportunity start something new in 2019. there will be a new quarterly column, “public libraries leading the way,” to highlight a technology-based innovation from a public library perspective. topics we are interested in include the following, but proposals on any other technology topic are welcome. • virtual and augmented reality • artificial intelligence • big data • internet of things • 3-d printing and makerspaces • robotics • drones • geographic information systems and mapping • diversity, equity, and inclusion and technology • privacy and cyber-security • library analytics and data-driven services • anything else related to public libraries and innovations in technology columns will be in the 1,000-1,500 word range and may include illustrations. these will not be research articles, but are meant to share practical experience with technology development or uses within the library. if you are interested in contributing a column, please submit a brief summary of your idea. i’m grateful to the ital editorial board, and especially to ida joiner and laurie willis, for their guidance in shaping this concept. regardless of whether you work in a public, or any other, library, i’m always happy to talk with you about how your experience and knowledge could be published as an article in ital. get in touch with me at varnum@umich.edu. kenneth j. varnum, editor

proquest pg. 90 consortia building: a handshake and a smile, island style patricia j. cutright in the evaluation of consortia and what constitutes these entities the discussion runs the gamut. from small, loosely knit groups who are interested in cooperation for the sake of improving services to large membershipdriven organizations addressing multiple interests, all recognize the benefits of partnerships. the federated states of micronesia are located in the western pacific ocean and cover 3.2 million square miles. throughout this scattering of small islands exists an enthusiastic library community of staff and users that have changed the outlook of libraries since 1991. motivated by the collaborative eff orts of this group, a project has unfolded over the past year that will furth er enhance library services through staff training and education while utilizing innovative technology. in assessing the library needs of the region this group crafted the document "the federated states of micronesia library services plan, 1999-2003," which coalesces the concepts, goals, and priorities put forward by a broad-based contingency of librarians. the compilation of the plan and its implementation demonstrate an understanding of the issues and exhibit the ingenuity, creativity, and willingness to solve problems on a g rand scale addressing the needs of all libraries in this vast pacific region. t he basic philosophy inher ent in librarianship is the concept of sharing. the di sse mination of information through material exchang e and interlibrary communication has enriched so cieties for centuries. th ere ar e few institutions other than libraries that are better equipped or suited for such cooperation and collaborati ve e ndeavors. with servic e as the lifeblood that runs through its inky veins , the librar y has the potential to be the driving force in an y community toward partnerships that a fford mutual benefit for all. the examination of the literatur e exposes a wid e rang e of perceptions as to the d e finition of what is a consortium . the term "consortia" conjur es up impressions that span the spectrum from highly or ganized, membership-driv en groups to loosely knit cadres focusing on impro ving services to their patrons however they can make it happen. in kopp 's pap er "library consortia and patricia j. cutright (cutright@eou .edu} is library

from a study conduct ed by ruth patrick on academic library consortia. in that study she identified four general types of consortia : • large consortia concerned primarily with computerized

consortia-demonstrating collaboration , cooperation , and partnerships. it is a multi type library cooperative that not only encompasses interaction among libraries but also betwe en agencies as well as governments. the librarians on the island of pohnpei, micron esia, and all the islands throughout the federated states of micronesia have embraced this consortia) attitud e whil e achieving much

west of hawaii, east of the philippines, south of japan and north of australia, the total land mass of all these tropical islands is fewer than 1,200 square miles with a population base estimated at no more than 111,500.3 a locationunique region, but nonetheless still plagued with all the problems associated with any geographically remote, economically depressed area found anywhere in the united states or elsewhere in the world. the federated states of micronesia is a small-island, developing nation that is aligned with the united states through a compact of free association, making it eligible for many u.s. federal programs. the economic base is centered around fisheries and marine-related industries, tourism, agriculture, and small-scale manufacturing. the average per capita income in 1996 was $1,657 for the four states of the fsm: kosrae, pohnpei, yap, and chuuk. thirteen major languages exist in the country, with english as the primary second language. the 607 different islands, atolls, and islets dot an immense expanse of ocean; this geographic condition presents challenges in implementing and enhancing library services and technology. 4 despite the extreme geographic and economic conditions, the college of micronesia-fsm national campus in collaboration with the librarians throughout the states have been successful in implementing nationwide projects. these endeavors have resulted in technical infrastructure and the foundation for information technology instruction supported through awards from the u.s. department of education, the title iii program, and the national science foundation. i collaboration: building bridges that cross the oceans the libraries in micronesia have shown an ongoing commitment to librarianship and cooperation since the establishment of the pacific islands association of libraries and archives (piala) in 1991. the organization is a micronesia-based regional association committed to fostering awareness and encouraging cooperation and resource sharing among libraries, archives, museums, and related institutions. piala was formed to address the needs of pacific islands librarians and archivists, with a special focus on micronesia; it is responsible for the common-thread cohesiveness shared by the librarians over the past eight years. the organization has grown to become an effective champion of the needs of libraries and librarians in the pacific region.s when piala was established, the most pressing areas of concern within the region were development of resource-sharing tools and networks among the libraries, archives, museums, and related institutions of the pacific islands. the development of continuing education programs and the promotion of technology and telecommunications applications throughout the region were areas targeted for attention. those concerns have changed little since the group's inception. building upon that original premise, in january 1999 a group of interested parties from throughout the federated states of micronesia met to draft a document they envisioned would lay the groundwork for library planning over the next five years. this strategic plan encompasses all library activity-services, staffing, and the impact technology will have on libraries in the region. the document, "the federated states of micronesia library services plan, 1999-2003," coalesces the concepts, goals, and priorities put forward by a broad-based contingent. in this meeting, the group addressed basic issues of library and museum service, barriers and solutions to improve service delivery, and additional funding and training resources for libraries and museums.6 the compilation of the plan crafted at the gathering demonstrated a thorough understanding of the issues that face the librarians of the vast region. it exhibits the ingenuity, creativity, and willingness to problem-solve on a grand scale in a way that addresses the needs of all libraries in the pacific region. the goals set forward by the writing session group illustrate the concerns impacting library populations throughout the fsm. the fsm has now established six major goals to carry out its responsibilities and the need for overall improvement in and delivery of library services: 1. establish or enhance electronic linkages between and among libraries, archives, and museums in the fsm. 2. enhance basic services delivery and promote improvement of infrastructure and facilities. 3. develop and deliver training programs for library staff and users of the libraries. 4. promote public education and awareness of libraries as information systems and sources for lifelong learning. 5. develop local and nationwide partnerships for the establishment and enhancement of libraries, museums, and archives. 6. improve quality of information access for all segments of the fsm population and extend access to information to underserved segments of the population. priorities the following are general priorities for the fsm library services plan. the priorities represent needs for overall improvement of the libraries, museums, and archives. the priorities are based on the fact that currently libraries, museums, and archives development is in its infancy in consortia building i cutright 91 reproduced with permission of the copyright owner. further reproduction prohibited without permission. the fsm. specific priorities will change from year to year as programs are developed. 1. establishment of new libraries and enhancement of existing library facilities to increas e accessibility of all fsm citizens to library resources and services. outer islands and remote areas generally have no access to libraries or information sources. new facilities or mechanisms need to be established to provide access to information resources for the public. existing public and school library facilities often lack adequate staffing, climate control, and electrical connections needed to meet the needs of the community. existing public and school libraries also need to improve their facilities and services delivery to meet the needs of disabled individuals and other special populations. 2. provide training and professional development for library operation and use of new information technologies. a survey held during the writing session indicated that public and school library staff do not currently possess the skills needed to effectively provide assistance in the use of new information technologies. well-designed training programs with mechanisms for follow-up technical assistance and support need to be developed and implemented. 3. promote collaboration and cooperation among libraries, museums, and archives for sharing of holdings and technical ability. limited holdings, financial capacity, and human resources are major barriers to improving library services. collaboration and cooperation are needed among libraries, museums, and archives to maximize scarce resources . 4. develop recommended standards and guidelines for library services in the fsm. the ability to share resources and information could be significantly increased by development and implementation of recommended standards and guidelines for library services. standardization could assist with sharing of holdings and holdings information, increase availability of technical assistance, and provide guidance as new libraries and library services are set up. 5. increase access to electronic information sources. existing public and school libraries have limited or no access to electronic linkages including basic services such as e-mail and connections to the internet. the priority need is to establish basic electronic linkages for all libraries, followed by extending access to electronic information to all users.7 i shifting into action with the drafting of this five-year plan, the librarians stated emphatically the need and desire to move ahead 92 information technology and libraries i june 2000 with haste and determination . as the plan was conceptualized and documented, a small cadre of librarians from the college of micronesia -fsm national campus, the public library, and high school library crafted two successful grant proposals which addressed: • a cooperative library automation project which is designed to evolve into a national union catalog (goal 1; priorities 3, 5); • the installation of intern et services that would link the college of micronesia-fsm campuses, the public library, and high school library (goals 1, 2, 6; priorities 1, 2, 3, 5); • the development and delivery of training programs for library staff and users of the libraries (goals 3, 4, 6; priority 2); and • the implementation of a viable resource-sharing and document delivery service for the nation (goal 1, 2, 5, 6; priorities 3, 4, 5). over the past year the awarding of grant funds has shifted the library community into high gear with the design and implementation of project activities that will fulfill the targeted needs. the automation project and internet connectivity a collaborative request submitted by the bailey olter high school (bohs) library and the pohnpei public library provided the funding necessary to computerize the manual card catalog system at bohs and upgrade the dated automated library system at pohnpei public library. since the college of micronesia-fsm campuses are automated, it was important for the high school library and the public library to install like systems to achieve a networkable automated system, facilitating the development of a union catalog for all th e libraries' holdings. this migration to an automated system promoted cooperation and resource sharing for the island libraries-opening a wealth of information for all island residents. the project entailed purchasing a turnkey cataloging and circulation system that will facilitate the cataloging and processing of new acquisitions for each library as well as the conversion of approximately five thousand volumes of material already owned by the public and high school libraries. through internet connectivity, which was integral to the project, the system would also serve as public access to the many holdings of the libraries for students, faculty, and town patrons through a union catalog to be established in the future. the development and deliv ery of training programs for library staff and users is linked to the implementation of a viable resource-sharing and document delivery service for the nation. stated earlier, the librarians of the federated states of micronesia accepted the challenge facing them in rampreproduced with permission of the copyright owner. further reproduction prohibited without permission. ing up for the twenty-first century. their prior experience laid the groundwork necessary to implement the training programs necessary to bring the library community the knowledge and skills needed. a survey administered during the writing session indicated that few public and school librarians have significant training in or use of electronic linkages or information technologies, nor are they actively using such technologies at present. of the fourteen public and school librarians in the four states of micronesia, none hold a master's degree from an accredited library school or library media specialist certification. an exception is the library staff at the com-fsm national campus, where two-thirds of the librarians hold professional credentials. significant effort is needed on a sustained basis for effective training in the understanding and use of information systems throughout the nation. where training has occurred, it has often been of an infrequent, short variety with little support for ensuring implementation at the work site. additionally, often there are no formal systems for getting answers to questions when problems do arise. in addressing the information needs for this population it is apparent that education is the key component for continued improvement of library services. this concern is evident in a paper by daniel barron, where it is stated that only 54 percent of librarians and 19 percent of staff in libraries serving communities considered to be rural (i.e., 25,000 people or fewer) have an ala-mls. 8 and dowlin proposes even more perplexing questions, "how can a staff with such an educational deficit be expected to accomplish all that will be demanded to enable their libraries to go beyond being a warehouse of popular reading materials? how can we expect them to change from pointers and retrievers to organizers and facilitators?" 9 micronesia is no different than any other state or country in wanting its population to have access to qualified staff, current resources, and services. it recognizes the libraries are inadequately staffed and many others have staff who are seriously undereducated to meet the expanded information needs of the people in their communities. if these libraries are to seize the opportunities suggested by the developing positive view, develop services to support this view, and market such a view to a wider range of citizens in their communities they must invest in the intellectual capital of their staffs. in order to carry out this charge, the following activities were designed to address the educational and training needs of the librarians in the fsm. as outlined in a recently funded institute of museums and library services (imls) national leadership grant, preparation has begun with the following activities, which will address the staffing and technology concerns described in fsm libraries: 1. recruit and hire an outreach services librarian to survey training needs, coordinate and plan training, and deliver or arrange for needed training. 2. develop a skills profile for all library, museum, and archival staff positions. 3. identify training contact or coordinator for each state. 4. develop and provide periodic updates to operational manuals for school and public libraries, museums, and archives. 5. recruit local students and assist them in seeking out scholarships for professional training off island. 6. design and implement programs to provide continuous training and on-site support in new technological developments and information systems (provided on-site and virtually). 7. establish a summer training institute offering training based on needs as determined by the outreach services librarian in collaboration with state coordinators and recruiting onand off-island expertise as instructors. 8. design and develop programs for orientation and training of users of information systems (provided on-site and virtually). 9. develop and implement a "train the trainer" program, which will have representation from all four states, that will ensure continuity and sustainability of the project for the years to come. 10 the primary requisite to initiating this project is the recruitment and hiring of the outreach services librarian who will then begin the activities as listed. a beginning cadre of librarians gleaned from the summer institute will become the trainers of the future, perpetuating a learning environment enhanced with advanced technology. breakthroughs in distance education, aided with advances in telecommunications, will significantly impact this project. on-site training will be imperative for the initial cadre of summer institute attendees to provide sound teaching skills and a firm understanding of the material at hand. follow-up training will be presented on each island by the trainer either on location or virtually with available technology. products such as web course in a box, webct, or nicenet will be analyzed for appropriate utilization as teaching tools. these products will take advantage of newly established internet connections on each island and, more importantly, will provide the interactive element that distinguishes this learning methodology from the "talking head" or traditional correspondence course approach. a web site designed for this project will provide valuable information and connectivity for not only the pacific library community but anyone worldwide who may be interested in innovative methods of serving remote populations. using computer conferencing and virtual communities technology, a video conferencing system such as 8 x 8 consortia building i cutright 93 reproduced with permission of the

(interisland telephone rates are too expensive for regular use as a teaching tool). to enhance the learning experience and information retrieval component for these librarians and the population they serve, the project also incorporates implementation of a viable resource-sharing, document delivery system capitalizing on a shared union catalog and using a service such as research library group's ariel product. with library budgets reflecting the critical economic climate of the nation, it becomes even more crucial for collaborative collection development and resource sharing to satisfy the needs of the library user. to maintain cost-effective communication and build a sense of community among the librarians, the messaging software icq has been installed on all participant hardware and utilized for group meetings, question and answer, and general correspondence. since icq operates as part of the internet, this package allows low-cost communication with maximum benefit in connecting the group. this technology will also be used as the primary mechanism for communication with an outside advisor who will provide expertise in the area of outreach services for rural populations. the realm of outreach services in libraries has always presented unique challenges that can now benefit greatly from current and emerging technologies. the definition of "outreach" is truly a matter of perspective, with the more traditional sense relating to a specific library servicing its own user or patron. but current practice regards "outreach" as a mere extension of services to all users whether they be a registered patron or colleague or peer. micronesia is a country where the proverbial phrase "the haves and the have-nots" is amplified. the recent (and ongoing) installation of internet services in the region has made possible many basic changes, but there still exists the reality that some of the sites for services proposed have nothing more than a common analog line and rudimentary services. as an example of the realities that exist, only 38 percent of the approximately 180 public schools in the fsm have access to reliable sources of electricity. another challenge for these libraries is the climate and environment, which has a significant impact on library facilities, equipment, and holdings. the fsm lies in the tropics, with temperatures ranging daily from 85 to 95 degrees with humidity normally 85 percent or higher.11 the high salt content in the ocean air wreaks havoc upon electrical equipment, and the favorable environs inside a library often entice everything from termites in the wooden bookcases to nesting ants in keyboards. from these examples it is apparent that the problems that trouble these libraries are not going to be solved with the magic bullet of technology. this reality constitutes the 94 information technology and libraries i june 2000 need for varying strategies and different aproaches to address the training requirements of the library staff. i summary the fsm library group, in particular the pohnpeian librarians, have accomplished much in the past year. the motivating factor for the flurry of activity that enveloped the libraries on pohnpei was spurred by the collaborative writing session in january 1999. a week-long "meeting of the minds" from libraries throughout micronesia produced the blueprint that will map the future of libraries and library service for years to come. these librarians stated their primary issues in delivering library services and came to a consensus on activities needed to address the issues. the "federated states of micronesia library services plan, 1999-2003" was crafted as a working document, a strategic plan for improving library services in the pacific region, and a commitment to achievement through collaboration. while in micronesia i observed the impact that the unification of ideas can have on the citizens of a community. in my fourteen-year tenure at eastern oregon university i have been exposed to the benefits of "consortium attitude" that come from cooperation and partnerships. time and again the university demonstrates the positive effects of what is referred to as "politics of entanglement." shepard describes the overriding philosophy that has been the recipe for success: the politics are really quite simple. we maintain an intricate pattern of relationships, any one of which might seem inconsequential. yet there is strength in the whole that is largely unaffected if a single relationship wanes. rather than mindlessly guarding turf, we seek to involve larger outside entities and in the ensnaring, to turn potential competitors into helpful partners .12 just as eastern oregon university has discovered, the libraries of the federated states of micronesia are learning the merits of entanglement. references and notes 1. james j. kopp, "library consortia and information technology: the past, the present, the promise," information technology

(aside to readers: as an impatient young man, i was struck less by the “magic” of the event than by an observation that i expressed on the spot: the response time was horrible—unacceptable. i opined that no one would put up with such a wait. i narrowly escaped with my scalp intact.) the national library of medicine (nlm) was perfecting the medical literature analysis and retrieval system

next-generation online catalog vufind incorporates many of the interactive web and social media technologies that the public uses online, including features from online booksellers and commercial search engines. the vufind search page is simple, containing only a single search box and a dropdown menu that gives users the option to search all fields or to search by title, author, subject, or isbn/issn (see figure 1). to combine searches using boolean logic or to limit to a particular language or format, the user must use the advanced search feature (see figure 2). the recordresults page displays results vertically, with each result containing basic item information, such as title, author, call number, location, item availability, and a graphical icon displaying the material’s format. the results page also has a column on the right side displaying “facets,” which are links that allow a user to refine their search and browse results using catalog data contained within the result set (see figure 3). vufind also contains a variety of web 2.0 features, such as the ability to tag items, create a list of favorite items, leave comments about an item, cite an item, and links to google book previews and extensive author biographies data mined from the internet. corresponding to the beginning of the vufind trial at uiuc, the university library purchased reviews, synopses, and cover images from syndetic solutions to further enhance both vufind and the existing webvoyage catalog. an additional appealing aspect of vufind was its speed; the carli installation of webvoyage is slow to load and is prone to time out while conducting searches. the uiuc library first provided vufind (http:// www.library.illinois.edu/vufind) at the beginning of the 2008 fall semester and expected it to be trialed through the end of the spring semester 2009. use statistics show that throughout the fall semester (september through december), there were approximately six thousand unique visitors each month, producing a total of more than thirty-eight thousand visits. spring statistics show use averaging more than ten thousand visitors a month, an increase most likely from word-of-mouth. librarians at both uiuc and carli were interested in what users thought about vufind, especially in relation to the usability of the interface. with this in mind, the library launched several forms of assessment during the spring semester. the first was a quantitative survey based on yale’s vufind usability testing.3 the second was a more extensive qualitative usability test that had users conducting sample searches in the interface and telling the facilitator their opinions. this article will discuss the hands-on usability portion of this study. survey responses that support the results presented herein will be reported in a separate venue. while this article only discusses vufind at a single institution, it does offer a generalized view of next-generation catalogs and how library users use such a catalog compared to a traditional online catalog. the vufind open–source, next-generation catalog system was implemented by the consortium of academic and research libraries in illinois as an alternative to the webvoyage opac system. the university of illinois at urbana-champaign began offering vufind alongside webvoyage in 2009 as an experiment in next generation catalogs. using a faceted search discovery interface, it offered numerous improvements to the uiuc catalog and focused on limiting results after searching rather than limiting searches up front. library users have praised vufind for its web 2.0 feel and features. however, there are issues, particularly with catalog data. v ufind is an open–source, next-generation catalog overlay system developed by villanova university library that was released to the public as beta in 2007 and version 1.0 in 2008.1 as of july 2009, four institutions implemented vufind as a primary catalog interface, and many more are either beta or internally testing it.2 more information about vufind, including the technical requirements and compatible opacs, is available on the project website (http://www.vufind.org). in illinois, the state consortium of academic and research libraries in illinois (carli) released a beta installation of vufind in 2008 on top of its webvoyage catalog database. the carli installation of vufind is a base installation with minor customizations to the carli catalog environment. some libraries in illinois utilize vufind as an alternative to their online catalog, including the university of illinois at urbana-champaign (uiuc), which currently advertises vufind as a more user friendly and faster version of the library catalog. as a part of the evaluation of nextgeneration catalog systems, uiuc decided to conduct hands-on usability testing during the spring of 2009. the carli catalog environment is very complex and comprises 153 member libraries throughout illinois, ranging from tiny academic libraries to the very large uiuc library. currently, 76 libraries use a centrally managed webvoyage system referred to as i-share. i-share is composed of a union catalog containing holdings of all 76 libraries as well as individual institution catalogs. library users heavily use the union catalog because of a strong culture of sharing materials between member institutions. carli’s vufind installation uses the records of the entire union catalog, but has library-specific views. each of these views is unique to the member library, but each library uses the same interface to view records throughout i-share. jennifer emanuel (emanuelj@illinois.edu) is digital services and reference librarian, university of illinois at urbana-champaign. usability of the vufind next-generation online catalog | emanuel 45 not simply find them.6 as a result, the past five years have been filled with commercial opac providers releasing next-generation library interfaces that overlay existing library catalog information and require an up-front investment by libraries to improve search capabilities. as these systems are inherently commercial and require a significant investment of capital, several open–source, next-generation catalog projects have emerged, such as vufind, blacklight, scriblio, and the extensible catalog project.7 these interfaces are often developed at one institution with their users in mind and then modified and adapted by other institutions to meet local needs. however, because they can be locally customized, libraries with significant technical expertise can have a unique interface that commercial vendors cannot compete against. one cannot discuss next-generation catalogs without mentioning the metadata that underlie opac systems. some librarians view the interface as only part of the problem of library catalogs and point to cataloging and metadata practices as the larger underlying problem. many librarians view traditional cataloging using machine-readable cataloging (marc), which has been used since the 1960s, as outdated because it was developed with nearly fifty-year-old technology in mind.8 however, because marc is so common and allows cataloging with a fine degree of granularity, current opac systems still utilize it. librarians have developed additional cataloging standards, such as dublin core (dc), metadata object description schema (mods), and functional requirements for bibliographic records (frbr), but none of these have achieved widespread adoption for cataloging printed materials. newly developed catalog projects, such as extensible catalog, are beginning to integrate these new metadata schemas, but currently others continue to use marc.9 many librarians also advocate to integrate folksonomy, or user tagging, into library catalogs. folksonomy is used by many library websites, most notably flickr, delicious, and librarything, each of which store user-submitted content that istagged with self-selected keywords that allow for easy retrieval and discovery.10 vufind integrates tagging into individual item records ■■ literature review librarians have complained about the usability of online catalogs since they were first created.4 when amazon.com became the go-to site for books and book information in the early 2000s, librarians and their users began to harshly criticize both opac interfaces and metadata standards.5 ever since north carolina state university announced a partnership with the commercial-search corporation endeca in 2006, librarians have been interested in the next generation of library catalogs and more broadly, discovery systems designed to help users discover library materials, figure 1. vufind default search figure 2. vufind advanced search figure 3. facets in vufind 46 information technology and libraries | march 2011 searching the library’s online catalog and were eager to see changes made to it. the test used was developed from a statewide usability test of different catalog interfaces usedin illinois. the test was adapted using the same sample searches, but was customized to the features and uses of vufind (see appendix). the vufind test was similar to the original test to allow a comparison of other catalog interfaces to vufind for internal evaluation purposes. i designed the test to allow subjects to perform a progressively complicated series of sample searches using the catalog while the moderator pointed out various features of the catalog interface. subjects were also asked what they thought about the search result sets and their opinions of the interface and navigation; they also were asked to perform specific tasks using vufind. the tasks were common library-catalog tasks using topics familiar at undergraduate–level students. the tasks ranged from a keyword search for “global warming” to a more complicated search for a specific compact disc by the artist prince. the tasks also included using the features associated with creating and using an account with vufind, such as adding tags and creating a favorite items list. through completing the test, subjects got an overview of vufind and were then asked to draw conclusions about their experience and compare it to other library catalogs they have used. the tests were performed in a small meeting room with one workstation set up with an install of the morae software, a microphone, and a web camera. morae is a very powerful software program developed by techsmith that records the screen on which the user is interacting with an interface, as well as environmental audio and video. although the study did not utilize all the features of the morae software, it was invaluable to the researcher to be able to review the entire testing experience with the same detail as when the test actually occurred in person. the study was carried out with the researcher sitting next to the workstation asking subjects to perform a task from the script while morae recorded all of their actions. once all fifteen subjects completed the test, the researcher watched the resulting videos and coded the answers into various themes on the basis of both broad subject categories and individual question answers. the researcher then gathered the codes into categories and used them to further analyze and gain insight into both the useful features of and problems with the vufind interface. ■■ analysis participants generally liked vufind and preferred it to the current webvoyage system. when asked to choose which catalog they would rather use, only one person, a faculty member, stated he would still use webvoyage. this faculty but does not pull tags from other sources; rather, users must tag items individually. additionally, next-generation catalogs offer a search mechanism that focuses on discovery rather than simply searching for library materials. users, accustomed to new ways of searching both on the internet and through commercial library indexing and abstracting databases, now search in a fundamentally different style than they did when opacs first became a part of library services. the online catalog is now just one of many tools that library users use to locate information and now covers fewer resources than it did ten to fifteen years ago. library users are now accustomed to using a single search box, such as with google; they also use nonlibrary online tools to find information about books and no longer view library catalogs as the primary place to look for books.11 as users are no longer accustomed to using the controlled language and particular searching methods of library catalogs because they have moved to discovering materials online, libraries must adapt to new way of obtaining information and focus not on teaching users how to locate library materials, but give them the tools to discover on their own.12 vufind is one option among many in the genre of next-generation or discovery-catalog tools. ■■ methods the study employed fifteen subjects who participated in individual, hands-on usability test sessions lasting an average of thirty minutes. i recruited volunteers though several methods, including posting to a university faculty and staff e-mail discussion list, an e-mail discussion lists aimed toward graduate students, and flyers in the undergraduate library. all means of recruitment stated that the library sought volunteer subjects to perform a variety of sample searches in a possible new library catalog interface. i also informed subjects that there was a gift card as a thank you for their time. all subjects had to sign a human subjects statement of informed consent approved by the university of illinois institutional review board. i sought a diverse sample, and therefore accepted the first five volunteers from the following pools: faculty and staff, graduate students, and undergraduate students. i felt that these three user groups were distinct enough to warrant having separate pools. the number of five users in each group was chosen because of jakob nielsen’s statement that five users will find 85 percent of usability problems and that fifteen users will discover all usability problems.13 although i did not specifically aim to recruit a diverse sample, the sample showed a large diversity in areas including age, library experience, and academic discipline. all subjects stated they had some experience usability of the vufind next-generation online catalog | emanuel 47 though there were questions as to how results were deemed relevant to the search statement as well as how they were ranked. participants were then asked to look at the right sidebar of the results page, which contains the facets. most users did not understand the term “facets,” with faculty and staff understanding the term more than graduate and undergraduate students did. one faculty member who understood the term facet noted that “facets are like a diamond with different sides or ways of viewing something.” however, when asked what term would be better to call the limiting options other than facet, several users suggested either calling the facets “categories” or renaming the column “refine search,” “narrow search,” or “sort your search.” participants were then asked to find how to see results for other i-share libraries. only two faculty members found i-share results quickly, and just half of the remaining participants were able to find the option at all. when asked what would make that option easier to find, most said they liked the wording, but the option needed to stand out more, perhaps with a different colored link or bolder type. two users thought having the location integrated as a facet would be the most useful way of seeing it. participants, however, quickly took to using the facets, as they were asked to use the climate change search results to find an electronic book published in 2008. no user had problems with this task, and several remarked that using facets was a lot easier than limiting to format and year before searching. the next task for participants was to open and examine a single record within their original climate change results (see figures 4 and 5). participants liked the layout, including the cover image with some brief title information, and a tabbed bar below showing additional information, such as more detailed description, holdings information, a table of contents, reviews, comments, and a link to request the item. several users remarked that they liked having information contained under tabs, but vufind organized each tab as a new webpage that made going back to previous tabs or the results page cumbersome. the only problem users had with the information contained within the tabs was the “staff view,” which contained the marc record information. most users looked at the marc record with confusion, including one graduate student who said, “if the staff view is of no use to the user, why even have it there?” one other useful feature that individual records in vufind contain is a link to an overlay window containing the full citation information for the item in both apa and mla formats. users were able to find this “cite this” link and liked having that information available. however, several participants noted that citation information would be much more beneficial if it could be easily exported to refworks or other bibliographic software. the next several searches used progressively higher-level member thought most of his searches were too advanced for the vufind interface and needed options that vufind did not have, such as limiting a search to an individual library or call number searching. this user did, however, specify that vufind would be easier to use for a fast and simple search. other users all responded very favorably to vufind, liking it better than any other online catalog they have used, with most stating that they wanted it as a permanent addition to the library. the most common responses to vufind were that the layout is easier on the eyes and displayed data much better than the webvoyage catalog; there were no comments about actual search results. several users stated that it was nice to be able to do a broad search and then have all limiting options presented to them as facets, allowing users to both limit after searching and letting them browse through a large number of search results. one user, an undergraduate student, stated she liked vufind because it “was new” and she always wants to try out new things on the internet. the first section of the usability test asked users to examine both the basic and advanced search options. users easily recognized how the interface functioned and liked having a single search box as the basic interface, noting that it looked more like a web search engine. they also recognized all of the dropdown menu options and agreed that the options included what they most often searched. however, four users wanted a keyword search. even though there is not a keyword search in webvoyage and there is an “all fields” menu option, participants seemed to think of the one box search universally as a keyword search and wanted that to be the default search option. one participant, an international graduate student, remarked that keyword is more understood by international students than the “all fields” search because, internationally, a field is not a search field but a scholarly field such as education or engineering. in the advanced search, all users thought the search options were clear and liked having icons to depict the various media formats. however, two users did remark that it would be useful to be able to limit by year on the advanced search page. the advanced search also is where the user can select one of seven languages, all of which are considered western languages, including latin and russian. two users, both international graduate students, stated that more languages would be beneficial, especially asian and more slavic languages. the university of illinois has separate libraries for asian and slavic materials, and these two participants said it would be useful to have search options that include the languages served by the libraries. the first task that participants were asked to do was an “all fields” search for “climate change.” they were instructed to look at the results page and an individual record to give feedback as to how they liked the layout and what they thought of the search results. upon looking at the results, all participants thought they were relevant, 48 information technology and libraries | march 2011 to items in which james joyce is the author, no participant had any problems, though several pointed out that there were three facets using his name—joyce, james; joyce, james avery; and joyce, j. a.—because of inconsistencies in cataloging (see figure 6). participants were next asked to search for an audio recording by the artist prince using the basic (single) search box. most participants did an “all fields” search for prince and attempted to use the facets to limit by a particular format. all but one was confident that they achieved the proper result, but there was confusion about the format. some participants were confused as to what format an audio recording was because the corresponding facet was for a music recording. a couple of users thought “audio recording” could be a spoken-word recording. most participants preferred that the format facets be more concrete toward a single actual physical format, such as a record, cassette, or a compact disc (see figure 7). physical formats appeared to resonate more with users than the broad cataloging term of “music recording.” a more specific format type (i.e., compact disc) is contained in the call number and should be straightforward to pull out as a facet. it appears vufind pulls the format information from marc field 245 subfield $h for medium rather than the call number (which at illinois can specify the format) or the 300 physical description field or another field such as a notes field that some institutions may use to specify the exact format. however, when participants were asked to further use facets to find prince’s first album, 1978’s for you, limitations with vufind became more apparent. each participant used a different method to search for this album, and none actually found the item either locally or in i-share, though the item has multiple copies available in both locations. most participants tried initially limiting by date because they were given that information. however, vufind’s facets focus on eras rather than specific years, which participants stated was frustrating as many items can fall under a broad era. also, the era facets brought up many more eras than one would consider an audio research skills and showed problems with both vufind and the catalog record data. the first search asked participants to do an “all fields” search for james joyce. all were able to complete the search, but there was notable confusion as to which records were written by james joyce and which were items about him. about half of the first-page results for this search did not list an author on the results page. vufind appears to pull the author field on the results page from the 100 field in the marc record, so if the 700 field is used instead for an editor, this information is not displayed on the results page. individual records do substitute the 700 field if the 100 field is not present, but this should also be the case on the initial results screen as well. several users thought it was strange that the results page often did not list the author, but an author was listed in the individual record. additionally, when asked to use the facets to limit figure 4. results set figure 5. record display figure 6. author facet figure 7. format facet usability of the vufind next-generation online catalog | emanuel 49 about both the reviews and comments that could be seen in the various records participants were asked to examine. many of the participants wanted more information as to where the reviews came from because this information was not clear. they also wanted to know whether the reviews or comments from catalog users had any type of moderation by a librarian. for the most part, participants liked having reviews inside the catalog records, but they liked having a summary even more. several users, all graduate students, expressed concern about the objectiveness of having reviews in the catalog, especially because it was not clear who did the review and feared that reviews may interject some bias that had no place in a library catalog record. one of these participants stated, “if i wanted reviews, i would just go to amazon. i don’t expect reviews, which can be subjective, to be in a library catalog—that is too commercial.” several undergraduate participants stated that reviews helped them decide whether the book was something that would be useful to them. the final task of the usability test asked participants to create an account with vufind because it is not connected to our user database. most users had no problems finishing this task, though they found some problems with the interface. first, it was not clear that users had to create an account and could not log in with their library number as they did in the library’s opac. second, the default field asks users for their barcode, which is not a term used at uiuc (users are assigned a library number). once logged in, participants were satisfied with the menu options and how their account information was displayed. finally, participants were asked, while logged in, to search for a favorite book and add it to their favorites list. all users liked the favorites-list feature, and many already knew of ways they could use it, but several wished they could create multiple lists and have the ability to arrange lists in folders. ■■ discussion participants thought favorably of the vufind interface and would use it again. they liked the layout of information much more than the current webvoyage interface and thought it was much easier to look at. they also had many comments that the color scheme (yellow and grey) was easier than the blues of the primary library opac. vufind also had more visual elements, such as cover images and icons representing format types that participants also commented on favorably. when asked to compare vufind to both the webvoyage catalog and amazon, only one participant indicated a preference for amazon, while the rest preferred vufind. the user who specified amazon, a faculty member, stated that that was where he always started searching for books; he would then search for specific titles in the recording, such as the 15th century. granted, the 15th century probably brings up music that originated in that era, not recorded then, but participants wanted the date to correspond to when an item was initially published or released. it appears that vufind pulls the era facet information from the subject headings and ignores the copyright or issue year. to users, the era facets are not useful for most of their search needs; users would rather limit by copyright or the original date of issue. another search that further highlighted problems searching for multimedia in vufind is the title search participants did for gone with the wind. everyone thought this search brought up relevant results, but when asked to determine whether the uiuc library had a copy of the dvd, many users expressed confusion. once again, the confusion was based on the inability to limit to a specific format. participants could use the facets to limit to a film or video, but not to a specific format. several participants stated that they needed specific formats because when they are doing a comparable search, they only want to find dvds. however, because all film formats are linked together under “film/video,” they must to go into individual records and examine the call number to determine the exact format. most participants stated clearly that “dvd” needed to be it’s own format facet and that entering a record to find the format required too much effort. participants also expressed frustration that the call number was the only place to determine specific format and believed that this information should be contained in the brief item information and not buried in the tabbed areas. the frustrations with the lack of specific formats also were evident when participants were asked to do an advanced search for a dvd on public speaking. all users initially thought the advanced search limiter for film/video was sufficient when they first looked at the advanced search options. however, when presented with an actual search (“public speaking”), they found that there should be more options and specific format choices up-front within the advanced search. another search that participants conducted was an author search for jack london. they then used the facets to find the book white fang. this search was chosen because the resulting records are mostly for older materials that often do not contain a lot of the additional information that newer records contain. participants looked at a specific record and then were asked what they thought of the information that was displayed. most answered that they would like as much information as you can give them, but were accepting of missing information. several participants stated that most people already know this book and thus did not need additional information. however, when pressed as to what information they would like added to the record, several users stated a summary would be the most useful. additionally, several users asked for more information 50 information technology and libraries | march 2011 the simplicity of the favorites listing feature, the difficulty of linking to other i-share library holdings, and the difficulties in using the facet categories. ■■ implications i intend to continue to perform similar usability tests on next-generation catalogs on a trial basis to examine one aspect regarding the future of online catalogs at uiuc. uiuc is looking at various catalog interfaces, of which vufind is one option, to see which best meets the needs of our users. users stated multiple times during testing that they find the current webvoyage interface to be very frustrating and will accept nearly anything that is an improvement, even if the new interface has some usability issues. vufind is not perfect for all searches, as shown by a lack of a call number search and the limitations in searching for multimedia options, but it does provide a more intuitive interface for most patrons. the future of vufind at uiuc is still open. development is currently stalled because of a lack of developer updates and internal staffing constraints both at uiuc and carli. however, because vufind is open–source, and the only ongoing cost is that of server maintenance, both carli and the library are continuing to display it as an option for searching the catalog. both carli and uiuc are closely examining other options for catalog interfaces that would provide patrons with a better search experience, but they have taken no further action to permanently adapt either vufind or to demo other options. despite its limitations, vufind is still a viable option for libraries with substantial technology expertise that are interested in a next-generation catalog interface at a low price. although it does have limitations, it has a better out-of-the-box interface than traditional opacs and should be considered alongside commercial options for any library thinking of adapting a catalog interface overlay. this usability test focused on one institution’s installation of vufind, which may or may not apply to other installations and other institutional needs. it would be interesting to study an installation of vufind at a smaller, nonresearch institution, where users have different searching needs and expectations related to a library’s opac. references 1. john houser, “the vufind implementation at villanova university,”

stated that it was commercial and more about marketing materials, while the library catalog just provided the basic information needed to evaluate materials without attempting to sell them to you. several participants also stated they checked amazon for book information, but generally did not like it because of its commercial nature; because vufind provides much of the same information as amazon, they will use vufind first in the future. participants also thought amazon was for a popular and not scholarly audience, making it not useful for academic purposes. most users did not have much to say about the webvoyage opac, except it was overwhelming, had too many words on the result screen, and was not pleasantly visual. participants were also asked to look at vufind, amazon, and webvoyage from a visual preference. again, participants believed that vufind had the best layout. they liked that vufind had a very clean and uncluttered interface and that the colors were few and easy on the eye. they also commented about the visuals contained (cover art and icons) in the records and the vertical orientation of vufind (webvoyage has a horizontal orientation) to display records. they also liked how the facets were displayed, though two users thought they would be better situated on the left side of the results because they scan websites from the left to the right. the one thing that was mentioned several times was vufind’s lack of the star rating system that amazon uses to quickly rate an item. participants thought such a system might be better than reviews because it allows users to quickly scan through the item and not have to read through multiple reviews. when asked to rate the ease of use for vufind, with 1 being easy and 5 being difficult, participants rated it an average of 1.92. faculty rated the ease at 1.6, graduate students at 1.75, and undergraduates at 2.8. undergraduates were more likely to get frustrated at media searching and thought that some of the facets related to media items were confusing, which they used to explain their lower scores. however, when asked if they would rather use vufind over the current library catalog (webvoyage), all but one participant enthusiastically stated they would use vufind. most users stated that although vufind was not perfect, it was still much better than the other library catalog because of the better layout, visuals, and ability to limit results. the only user that specified they would still rather use the webvoyage catalog believed it had more options for advanced search, such as call number searching, which vufind lacked. there are, however, several changes that could make vufind more useful to our users that came out of usability testing. some of these are easy to implement on a local level, and others would improve the base build of vufind. a number of issues arose from usability testing, but the largest issues are the lack of refworks integration,

students lack the information and communication technology (ict) literacy skills necessary to navigate, evaluate, and use the overabundance of information available today. this paper describes the development and early administrations of ets’s iskills assessment, an internet-based assessment of information literacy skills that arise in the context of technology. from the earliest stages to the present, the library community has been directly involved in the design, development, review, field trials, and administration to ensure the assessment and scores are valid, reliable, authentic, and useful. t echnology is the portal through which we interact with information, but there is growing belief that people’s ability to handle information—to solve problems and think critically about information—tells us more about their future success than does their knowledge of specific hardware or software. these skills—known as information and communications technology (ict) literacy—comprise a twenty­first­century form of literacy in which researching and communicating information via digital environments are as important as reading and writing were in earlier centuries (partnership for 21st century skills 2003). although today’s knowledge society challenges stu­ dents with overabundant information of often dubious quality, higher education has recognized that the solution cannot be limited to improving technology instruction. instead, there is an increasingly urgent need for students to have stronger information literacy skills—to “be able to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information” (american library association 1989)—and apply those skills in the context of technology. regional accreditation agencies have integrated information lit­ eracy into their standards and requirements (for example, middle states commission on higher education 2003; western association of schools and colleges 2001), and several colleges have begun campuswide initiatives to improve the information literacy of their students (for example, the california state university 2006; university of central florida 2006). however, a key challenge to designing and implementing effective information lit­ eracy instruction is the development of reliable and valid assessments. without effective assessment, it is difficult to know if instructional programs are paying off—whether students’ information literacy skills are improving. ict literacy skills are an issue of national and inter­ national concern as well. in january 2001, educational testing service (ets) convened an international ict literacy panel to study the growing importance of exist­ ing and emerging information and communication tech­ nologies and their relationship to literacy. the results of the panel’s deliberations over fifteen months highlighted the growing importance of ict literacy in academia, the workplace, and society. the panel called for assessments that will make it possible to determine to what extent young adults have obtained the combination of techni­ cal and cognitive skills needed to be productive mem­ bers of an information­rich, technology­based society (international ict literacy panel 2002). this article describes ets’s iskills assessment (for­ merly “ict literacy assessment”), an internet­based assessment of information literacy skills that arise in the context of technology. from the earliest stages to the pres­ ent, the library community has been directly involved in the design, development, review, field trials, and admin­ istration to ensure the assessment and scores are valid, reliable, authentic, and useful. ■ motivated by the library community although the results of the international ict literacy panel provided recommendations and a framework for an assessment, the inspiration for the current iskills assessment came more directly from the higher educa­ tion and library community. for many years, faculty and administrators at the california state university (csu) had been investigating issues of information literacy on their campuses. as part of their systemwide information competence initiative that began in 1995, researchers at csu undertook a massive ethnographic study to observe students’ research skills. the results suggested a great many shortcomings in students’ infor­ mation literacy skills, which confirmed librarian and classroom faculty anecdotal reports. however, clearly such a massive data collection and analysis effort would be unfeasible for documenting the information literacy skills of students throughout the csu system (dunn 2002). gordon smith and the late ilene rockman, both of the csu chancellor ’s office, discussed with ets the idea of developing an assessment of ict literacy that could support csu’s information competence initiative as well as similar initiatives throughout the higher edu­ cation community. irvin r. katz irvin r. katz (ikatz@ets.org) is senior research scientist in the research and development division at educational testing service. testing information literacy in digital environments: ets’s iskills assessment � information technology and libraries | september 2007� information technology and libraries | september 2007 ■ national higher education ict literacy initiative in august 2003, ets established the national higher education ict literacy initiative, a consortium of seven colleges and universities that recognized the need for an ict literacy assessment targeted at higher educa­ tion. representatives of these institutions collaborated with ets staff to design and develop the iskills assessment. the consortium built upon the work of the international panel to explicate the nature of ict literacy in higher education. over the ensuing months, repre­ sentatives of consortium institutions served as subject­ matter experts for the assessment design and scoring implementation. the development of the assessment followed a process known as evidence­centered design (mislevy, steinberg, and almond 2003), a systematic approach to the design of assessments that focuses on the evidence (student performance and products) of proficiencies as the basis for constructing assessment tasks. through the evidence­ centered design process, ets staff (psychometricians, cognitive psychologists, and test developers) and sub­ ject­matter experts (librarians and faculty) designed the assessment by considering first the purpose of the assess­ ment and by defining the construct—the knowledge and skills to be assessed. these decisions drove discussions of the types of behaviors, or performance indicators, to serve as evidence of student proficiency. finally, simulation­ based tasks designed around authentic scenarios were crafted to elicit from students the critical performance indicators. katz et al. (2004) and brasley (2006) provide a detailed account of this design and development process, illustrating the critical role played by librarians and other faculty from higher education. ■ ict literacy = information literacy + digital environments consortium members agreed with the conclusions of the international ict literacy panel that ict literacy must be defined as more than technology literacy. college students who grew up with the internet (the “net generation”) might be impressively technologically literate, more accepting of new technology, and more technically facile than their parents and instructors (oblinger and oblinger 2005). however, anecdotally and in small­scale studies, there is increasing evidence that students do not use technology effectively when they conduct research or communicate (rockman 2004). many educators believe that students today are less information savvy than earlier generations despite having powerful information tools at their disposal (breivik 2005). ict literacy must bridge the ideas of information literacy and technology literacy. to do so, ict literacy draws out the technology­related components of infor­ mation literacy as specified in the often­cited standards of the association of college and research libraries (acrl) (american library association 1989), focusing on how students locate, organize, and communicate information within digital environments (katz 2005). this conflu­ ence of information and technology directly reflects the “new illiteracy” concerns of educators: students quickly adopt new technology, but do not similarly acquire skills for being critical consumers and ethical producers of information (rockman 2002). students need training and practice in ict literacy skills, whether through general education or within discipline coursework (rockman 2004). the definition of ict literacy adopted by the con­ sortium members reflects this view of ict literacy as information literacy needed to function in a technological society: ict literacy is the ability to appropriately use digital technology, communication tools, and/or networks to solve information problems in order to function in an information society. this includes having the ability to use technology as a tool to research, organize, and communicate information and having a fundamental understanding of the ethical/legal issues surrounding accessing and using information (katz et al. 2004, 7). consortium members further refined this defini­ tion, identifying seven performance areas (see figure 1). these areas mirror the acrl standards and other related standards, but focus on elements that were judged most central to being sufficiently information literate to meet the challenges posed by technology. ■ ets’s iskills assessment ets’s iskills assessment is an internet­delivered assess­ ment that measures students’ abilities to research, orga­ nize, and communicate information using technology. the assessment focuses on the cognitive problem­solving and critical­thinking skills associated with using technol­ ogy to handle information. as such, scoring algorithms target cognitive decision­making rather than technical competencies. the assessment measures ict literacy through the seven performance areas identified by con­ sortium members, which represent important problem­ solving and critical­thinking aspects of ict literacy skill (see figure 1). assessment administration takes approx­ imately seventy­five minutes, divided into two sec­ tions lasting thirty­five and forty minutes, respectively. article title | author 5testing information literacy in digital environments | katz 5 figure 1. components of ict literacy define: understand and articulate the scope of an information problem in order to facilitate the electronic search for information, such as by: ■ distinguishing a clear, concise, and topical research question from poorly framed questions, such as ones that are overly broad or do not otherwise fulfill the information need; ■ asking questions of a “professor” that help disambiguate a vague research assignment; and ■ conducting effective preliminary information searches to help frame a research statement. access: collect and/or retrieve information in digital environments. information sources might be web pages, databases, discussion groups, e-mail, or online descriptions of print media. tasks include: ■ generating and combining search terms (keywords) to satisfy the requirements of a particular research task; ■ efficiently browsing one or more resources to locate pertinent information; and ■ deciding what types of resources might yield the most useful information for a particular need. evaluate: judge whether information satisfies an information problem by determining authority, bias, timeliness, relevance, and other aspects of materials. tasks include: ■ judging the relative usefulness of provided web pages and online journal articles; ■ evaluating whether a database contains appropriately current and pertinent information; and ■ deciding the extent to which a collection of resources sufficiently covers a research area. manage: organize information to help you or others find it later, such as by: ■ categorizing e-mails into appropriate folders based on a critical view of the e-mails’ contents; ■ arranging personnel information into an organizational chart; and ■ sorting files, e-mails, or database returns to clarify clusters of related information. integrate: interpret and represent information, such as by using digital tools to synthesize, summarize, compare, and contrast information from multiple sources while: ■ comparing advertisements, e-mails, or web sites from competing vendors by summarizing information into a table; ■ summarizing and synthesizing information from a variety of types of sources according to specific criteria in order to compare information and make a decision; and ■ re-representing results from an academic or sports tournament into a spreadsheet to clarify standings and decide the need for playoffs. create: adapt, apply, design, or construct information in digital environments, such as by: ■ editing and formatting a document according to a set of editorial specifications; ■ creating a presentation slide to support a position on a controversial topic; and ■ creating a data display to clarify the relationship between academic and economic variables. communicate: disseminate information tailored to a particular audience in an effective digital format, such as by: ■ formatting a document to make it more useful to a particular group; ■ transforming an e-mail into a succinct presentation to meet an audience’s needs; ■ selecting and organizing slides for distinct presentations to different audiences; and ■ designing a flyer to advertise to a distinct group of users. © 2007 educational testing service. all rights reserved. 6 information technology and libraries | september 20076 information technology and libraries | september 2007 during this time, students respond to fifteen interactive, performance­based tasks. each interactive task presents a real­world scenario, such as a class or work assignment, that frames the infor­ mation problem. students solve information­handling tasks in the context of simulated software (for example, e­mail, web browser, library database) having the look and feel of typical applications. there are fourteen three­ to five­minute tasks and one fifteen­minute task. the three­ to five­minute tasks target a single perfor­ mance area, while the fifteen­minute tasks comprise more complex problem­solving scenarios that target multiple performance areas. the simpler tasks contribute to the overall reliability of the assessment, while the more com­ plex task focuses on the richer aspects of ict literacy performance. in the assessment, a student might encounter a sce­ nario that requires him or her to access information from a database using a search engine (see figure 2). the results are tracked and strategies scored based on how he or she searches for information, such as key words chosen, search strategies refined, and how well the information returned meets the needs of the task. the assessment tasks each contain mechanisms to keep students from pursuing unproductive actions in the simulated environment. for example, in an internet browsing task, when the student clicks on an incorrect link, he might be told that the link is not needed for the current task. this message cues the student to try an alter­ native approach while still noting for scoring purposes that the student made a misstep. in a similar way, the student who fails to find useful (or any) journal articles in her database search might receive an instant message from a “teammate” providing her with a set of journal articles to be evaluated. these mechanisms potentially keep students from becoming frustrated (for example, via a fruitless search) while providing the opportunity for the students to demonstrate other aspects of their skills (for example, evaluation skills). the scoring for the iskills assessment is completely automated. unlike a multiple­choice question, each simu­ lation­based task provides many opportunities to collect information about a student and allows for alternative paths leading to a solution. scored responses are pro­ duced for each part of a task, and a student’s overall score on the test accumulates the individual scored responses across all assessment tasks. the assessment differs from existing measures in sev­ eral ways. as a large­scale measure, it was designed to be administered and scored across units of an institution or across institutions. as a simulation­based assessment, the tasks go beyond what is possible in multiple­choice format, providing students with the look and feel of interactive digital environments along with tasks that elicit higher­order critical­thinking and problem­solving skills. as a scenario­based assessment, students become engaged in the world of the tasks, and the task scenarios describe the types of assignments students should be see­ ing in their ict literacy instruction as well as examples of workplace and personal information problems. ■ two levels of assessments the iskills assessment is offered at two levels: core and advanced. the core level was designed to assess readi­ ness for the ict literacy demands of college. it is targeted at high school seniors and first­year college students. the advanced level was designed to assess readiness for the ict literacy challenges in transitioning to higher­level college coursework, such as moving from sophomore to junior year or transferring from a two­year to a four­year institution. the advanced level targets students in their second or third year of post­secondary study. the key difference between the core and advanced levels is in the difficulty of the assessment tasks. tasks in the core level are designed to be easier; examinees are presented with fewer options, the scenarios are more straightforward, and the reasoning needed for each step in a task is simpler. an advanced task might require an individual to infer the search terms needed from a gen­ eral description of an information need; the correspond­ ing core task would state the information need more explicitly. in a task of evaluating web sites, the core level might present a web site with many clues that it is not figure 2. in the iskills assessment, students demonstrate their skills at handling information through interaction with simulated software. in this example task, students develop a search query as part of a research assignment on earthquakes. © 2007

directly describes the authors as students). the cor­ responding advanced task would present fewer cues of the web site’s origin (for example, a professional look, but careful reading reveals the web site is by students). ■ score reports for individuals and institutions both levels of the assessment feature online delivery of score reports for individuals and for institutions. the individual score report is intended to help guide students in their learning of ict literacy skills, aiding identifica­ tion of students who might need additional ict literacy instruction. the report includes an overall ict literacy score, a percentile score, and individualized feedback on the student’s performance (see figure 3). the percentile compares students to a reference group of students who took the test in early 2006 and who fall within the target population for the assessment level (core or advanced). as more data are collected from a greater number of institutions, these reference groups will be updated and, ideally, approach nationally representative norms. score reports are available online to students, usually within one week. high schools, colleges, and universities receive score reports that aggregate results from the test­takers at their institution. the purpose of the reports is to provide an overview of the students in comparison with a reference group. these reports are available to institutions online after at least fifty students have taken either the core or advanced level test—that is, when there are sufficient num­ bers to allow reporting of reliable scores. figure 4 shows a graph from one type of institutional report. users have the option to specify the reference group (for example, all students, all students at a four­year institution) and the subset of test­takers to compare to that group (for exam­ ple, freshmen, students taking the test within a particular timeframe). a second report summarizes the performance feedback of the individual reports, providing percentages of students who received the highest score on each aspect of performance (each of the fourteen short tasks are scored on two or three different elements). finally, institutions can conduct their own analyses by downloading the data of their test­takers, which include each student’s responses to the background questions, iskills score, and responses to institution­specified questions. ■ testing the test a variety of specialists contributed to the development of ets’s iskills assessment: librarians, classroom fac­ ulty, education administrators, assessment specialists, researchers, user­interface and graphic designers, and systems developers. the team’s combined goal was to produce a valid, reliable, authentic assessment of ict literacy skills. before the iskills assessment produced figure 3. first page of a sample score report for an individual. the subsequent pages contain additional performance feedback. figure 4. sample portion

specialists—both ets and ict literacy experts—subjected the assess­ ment to a variety of review procedures at many stages of development. these reviews ranged from weekly teleconferences with consortium members during the initial development of assessment tasks (january–july 2004), to small­scale usability studies in which ets staff observed individual students completing assessment tasks (or mockups of assessment tasks), to field trials that mirrored actual test delivery. the usability studies investigated students’ comprehension of the tasks and testing environment as well as the ease of use of the simulated software in the assessment tasks. the field trials provided opportunities to collect performance data and test the automated scoring algorithms. in some cases, ets staff fine­tuned the scoring algorithms (or developed alternatives) when the scores produced were not psychometrically sound, such as when one element of students’ scores was inconsistent with their overall performance. through these reviews and field trials, the iskills assessment evolved to its current form, targeting and reporting the performance of individuals who complete the seventy­five­minute assessment. in some cases, feedback from experts and field trial participants led to significant changes. for example, the iskills assess­ ment began in 2005 as a two­hour assessment (at that time called the ict literacy assessment), that reported scores only to institutions on the aggregated perfor­ mance of their participating students. some students entering higher education found the 2005 assessment excessively difficult, which led to the creation of the easier core level assessment. table 1 outlines the participation volumes for the field trials and test administrations. during each field trial, as well as during the institutional administration, feedback was collected from students on their experience with the test via a brief exit survey. table 2 summarizes some results of the exit survey. student reactions to the test were reasonably consistent: most students enjoyed taking the test and found the tasks realistic. in writ­ ten comments, students taking the institutional assess­ ment found the experience rewarding but exhausting, and thought the amount of reading excessive. student feedback directly influenced the design of the core and advanced level assessments, including the shorter test­ table 1. chronology of field trials and test administrations date administration approximate no. of students approximate no. of participating institutions july–september

set time frames. beginning in august 2006, the core and advanced level assessments switched to continuous testing: instead of a specific testing window, institutions create testing sessions to suit the convenience of their resources and students. the tests are still administered in a proctored lab environment, however, to preserve the integrity of the scores. ■ student performance almost 6,400 students at sixty­three institutions par­ ticipated during the first administrations of the core and advanced level iskills assessments between january and may 2006. (some institutions administered both the core and advanced level assessments.) test­takers consisted of 1,016 high­school students, 753 community college students, and 4,585 four­year college and university stu­ dents. institutions selected students to participate based on their assessment goals. some chose to test students enrolled in a particular course, some recruited a random sample, and some issued an open invitation and offered gift certificates or other incentives. because the sample of students is not representative of all united states institu­ tions nor all higher education students, these results do not necessarily generalize to the greater population of college­age students and should therefore be interpreted with caution. even so, the preliminary results reveal interesting trends in the ict literacy skills of participat­ ing students. overall, students performed poorly on both the core and advanced level, achieving only about half of the possible points on the tests. informally, the data suggest that students generally do not consider the needs of an audience when communicating information. for exam­ table 2. student feedback from the institutional assessment and individual assessments’ field trials statement % agreeing institutional assessment (n=4,898) advanced level field trials (n=736) core level field trials (n=648) i enjoyed taking this test. 61 59 67 this test was appropriately challenging. 90 90 86 i have never taken a test like this one before. 90 90 89 to perform well on this test requires thinking skills as well as technical skills. 95 93 94 i found the overall testing interface easy to use (even if the tasks themselves might have been difficult). 83 82 85 my performance on this test accurately reflects my ability to solve problems using computers and the internet. 63 56 67 i didn’t take this test very seriously. 25 25 23 the tasks reflect activities i have done at school, work, or home. 79 77 78 the software tools were unrealistic. n/a 21 24 10 information technology and libraries | september 200710 information technology and libraries | september 2007 ple, they do not appear to recognize the value of tailor­ ing material to an audience. regarding the ethical use of information, students tend not to check the “fair use” policies of information on the assessment’s simulated web sites. unless the usage policy (for example, copy­ right information) is very obvious, students appeared to assume that they may use information obtained online. on the positive side, test­takers appeared to recognize that .edu and .gov sites are less likely to contain biased material than .com sites. eighty percent of test­takers correctly completed an organizational chart based on e­mailed personnel information. most test­takers cor­ rectly categorized e­mails and files into folders. and when presented with an unclear assignment, 70 percent of test­takers selected the best question to help clarify the assignment. during a task in which students evaluated a set of web sites: ■ only 52 percent judged the objectivity of the sites cor­ rectly; ■ sixty­five percent judged the authority correctly; ■ seventy­two percent judged the timeliness correctly; and ■ overall, only 49 percent of test­takers uniquely identi­ fied the one web site that met all criteria. when selecting a research statement for a class assign­ ment: ■ only 44 percent identified a statement that captured the demands of the assignment; ■ forty­eight percent picked a reasonable but too broad statement; and ■ eight percent picked statements that did not address the assignment. when asked to narrow an overly broad search: ■ only 35 percent selected the correct revision; and ■ thirty­five percent selected a revision that only mar­ ginally narrowed the search results other results suggest that these students’ ict literacy needs further development: ■ in a web search task, only 40 percent entered mul­ tiple search terms to narrow the results; ■ when constructing a presentation slide designed to persuade, 12 percent used only those points directly related to the argument; ■ only a few test­takers accurately adapted existing material for a new audience; and ■ when searching a large database, only 50 percent of test­takers used a strategy that minimized irrelevant results. ■ validity evidence the goal of the iskills assessment is to measure the ict literacy skills of students—higher scores on the assess­ ment should reflect stronger skills. evidence for this validity argument has been gathered since the earliest stages of assessment design, beginning in august 2003. these documentation and research efforts, conducted at ets and at participating institutions, include: ■ the estimated reliability of iskills assessment scores is .88 (cronbach alpha), which is a measure of test score consistency across various administrations. this level of reliability is comparable to that of many other respected content­based assessments, such as the advanced placement exams. ■ as outlined earlier, the evidence­centered design approach ensures a direct connection between experts’ view of the domain (in this case, ict literacy), evi­ dence of student performance, design of the tasks, and the means for scoring the assessment (katz et al. 2004). through the continued involvement of the library community in the form of the ict literacy national advisory committee and development committees, the assessment maintains the endorsement of its con­ tent by appropriate subject­matter experts. ■ in november 2005, a panel of experts (librarians and faculty representing high schools, community colleges, and four­year institutions from across the united states) reviewed the task content and scoring for the core level iskills assessment. after investigat­ ing each of the thirty tasks and their scoring in detail, the panelists strongly endorsed twenty­six of the tasks. four tasks received less strong endorsement and were subsequently revised according to the committee’s recommendations. ■ students’ self­assessments of their ict literacy skills align with their scores on the iskills assessment (katz and macklin 2006). the self­assessment measures were gathered via a survey administered before the 2005 assessment. interestingly, although students’ confidence in their ict literacy skills aligned with their iskills scores, iskills scores did not correlate with the frequency with which students reported per­ forming ict literacy activities. this result supports librarians’ claims that mere frequency of use does not translate to good ict literacy skills, and points article title | author 11testing information literacy in digital environments | katz 11 to the need for ict literacy instruction (oblinger and hawkins 2006; rockman 2002). ■ several other validity studies are ongoing, both at ets and at collaborating institutions. these stud­ ies include using the iskills assessment in pre­post evaluations of educational interventions, detailed comparisons of student performance on the assess­ ment and on more real­world ict literacy tasks, and comparisons of iskills assessment scores and scores from writing portfolios. ■ national ict literacy standards and setting cut scores in october 2006, the national forum on information literacy, an advocacy group for information literacy policy (http://www.infolit.org/), announced the formation of the national ict literacy policy council. the policy coun­ cil—composed of representatives from key policy­making, information­literacy advocacy, education, and workforce groups—has the charter to draft ict literacy standards that outline what students should know and be able to do at different points in their academic careers. beginning in 2007, the council will first review existing standards docu­ ments to draft descriptions for different levels of perfor­ mance (for example, minimal ict literacy, proficient ict literacy), creating a framework for the national ict literacy standards. separate performance levels will be defined for the corresponding target population for the core and advanced assessments. these performance­level descrip­ tions will be reviewed by other groups representing key stakeholders, such as business leaders, healthcare educa­ tors, and the library community. the council also will recruit experts in ict literacy and information­literacy instruction to review the iskills assessment and recommend cut scores corresponding to the performance levels for the core and advanced assess­ ments. (a cut score represents the minimum assessment score needed to classify a student at a given performance level.) the standards­based cut scores are intended to help educators determine which students meet the ict literacy standards and which may need additional instruction or remediation. the council will review these recommended cut scores and modify or accept them as appropriately reflecting national ict literacy standards. ■ conclusions ets’s iskills assessment is the first nationally available measure of ict literacy that reflects the richness of that area through simulation­based assessment. owing to the 2005 and 2006 testing of more than ten thousand students, there is now evidence consistent with anec­ dotal reports of students’ difficulty with ict literacy despite their technical prowess. the results reflect poor ict literacy performance not only by students within one institution, but across the participating sixty­three high schools, community colleges, and four­year colleges and universities. the iskills assessment answers the call of the 2001 international ict literacy panel and should inform ict literacy instruction to strengthen these criti­ cal twenty­first­century skills for college students and all members of society. ■ acknowledgments i thank karen bogan, dan eignor, terry egan, and david williamson for their comments on earlier drafts of

butler. midwinter 1973 minutes approved. motion. mr. shoffner moved to approve the minutes of the midwinter 1973 board meetings. seconded by mr. fasana. carried. las vegas annual meeting minutes accepted. a correction on page one of the las vegas annual meeting minutes was noted: mr. auld's name should be added to the list of guests present. motion. mr. fasana moved that the minutes of the isad board meetings at the las vegas annual conference be accepted as corrected. seconded by mrs. martin. carried. isad history committee. the matter of appointing members to the isad history committee, whose function is to prepare a history of isad for ala's centennial celebration in 1976, was considered. mr. shoffner said that during the time he was president, he had rendered the isad history committee inactive. it was suggested by mr. kilgour that a historian would serve the purpose better than a committee. mr. shoffner remarked that he anticipated the chairman would be a historian. mrs. martin asked whether a check could be made first whether ala is planning to publish any document for the centennial celebration that would make any preparation by an isad committee or historian worth while. mr. kilgour remarked that isad definitely should be included if ala did plan to publish any document and asked the board to give an "ok" to appoint a historian. motion. mr. fasana moved that the ad hoc isad history committee 44 journal of library automation vol. 7/1 march 197 4 be abolished and recommended that the president be given the right to appoint a historian if ala planned to publish a centennial document. seconded by mr. auld. carried. ala dues structure. mr. hammer explained the information submitted to the board concerning the proposed ala. dues structure. the basic fee for ala membership under this proposed dues structure would be $35. membership in each division would be an additional $15. in es~ sence, each division would be on its own financially:· if there are not enough memberships to support a division, as could be the case, the division would cease to exist. !sad could support itself with its present membership, but there is no. way of knowing how many !sad members would still select !sad if the choice of two divisions included in the dues was removed. the divisions that publish a journal would attract membership much more easily than those that do not provide a journal. mr. hammer further remarked that the proposed dues schedule indicates that the divisions must prove themselves with membership dues as their only support, but this does not apply to ala committees, scmai, units such as the office for intellectual freedom, office for library service to the disadvantaged, and the administrative and support units of ala. these units may be of great value to ala, but if one tinit is forced to prove its value financially, then it seems that all should have to prove themselves. the divisions would be expected to depend on their own resources, e.g., if the division runs out of postage ·money, there would be no further mailings. the divisions would be expected to pay for their support services.· the idea is very closeto the federation plan which has been circulated for some time. in answer to the question of how a new division would get started, mr. hammer replied that he assumed there would have to be enough memberships to provide for it financially. mr. shoffner suggested that the discussion be divided into two parts: ( 1) the principle involved; and ( 2) the financial aspect. · the following points were brought up in the ensuing discussion by the board regarding the proposed dues structure: . starting a new division could be a problem; perhaps it could be subsidized for a stated time, after which the division: would be self-sufficient. the proposed separation of dues, however, would force a clarity in ex~ penditures of. ala in respect to how the divisions would benefit. some divisions could not be self-supporting and yet are producing important contributions for ala. ' ' a division would be at the mercy of the ala supporting units. if a sup~· port unit was not efficient, the divisions would be handicapped in the services to their members. would a division be able to know enough in advance how much money could be counted on for program planning? the answer was "yes" based highlights of meetings 45 on past membership, except in the first year. the income would be predicted on the basis of the previous year's income. an excess of income would remain in the division's funds. if the division income fell short of the anticipated amount, it would have no back-up from ala as it has presently. a person could not join one or more of the divisions without joining ala. some divisions could become part of a stronger division, e.g., a division could be broken up and absorbed into several other divisions with related interests. was there any plan to absorb or redirect these divisions which obviously could not be self-supporting? nothing has been announced so far. if a division got into financial difficulties, it could not cut down on its professional staff as a professional staff is needed to maintain ala's status with the internal revenue service. it was noted that there were more important reasons than this for maintaining a professional staff . . · this proposal was drafted by the then deputy director ruth warncke in 1970. the board was informed that a cost study of ala was recently discussed by staff members, but the reply has been that it would take five years to make such a study. the isad board disagreed with the period of five years, but stated that it could take a year. . · a division should be allowed to set up its own budget under this pro~ posal as well as have a voice in ala policy. · · the proposal appeared to be unfair in some points: ( 1) some divisions would have about twice their present income through memberships, while isad would break about even; ( 2) life members would be entitled to membership in all divisions; ( 3) apparently institutions without a group insurance plan of their own could join ala for $35 and be entitled to the gioup insurance for their staffs; at some point an examination of the privileges in each category of membership should be made; and ( 4) if the $35 ala membership fee were increased in the future, this would directly affect membership in the divisions. the isad budget for the 1973/74 year is approximately $47,000 and the journal of library automation $23,000, or a total of approximately $.70,000. if isad membership should fall back to 3,000 members and the membership fee were $25, isad could still be viable. "mr. kilgour's poll of the board revealed all were in favor of the principle of more or less independent divisions, but with reservations; the following was therefore moved: · 'motion. mr. shoffner moved that the isad board favors the prin. ciple of divided annual fees for ala and for its divisions subject to: ' · ( 1) division determination of the fee structure for division memberships and publications; ( 2) division participation in the governance of ala headquarters activities. seconded by mr. fasana. motion carried. ·selective dissemination of information system. mr. 46 journal of library automation vol. 7/1 march 1974 hammer presented a proposal for establishing on a subscription basis a selective dissemination of information system for ala members (see exhibit 1). mter discussion it was decided that mr. hammer would contact ohio state university library and obtain information on exact procedure as to how this would be run, how it would be publicized, who would develop the profiles, who would handle the subscriptions, the cost to the division, etc., and then repmt to the board. co-sponsorship of basic data processing seminars. mr. hammer presented a proposal to the board regarding co-sponsorship of basic data processing seminars with organizations outside isad, such as ibm and dataflow systems, inc. in bethesda, maryland. in the past isad seminars have generally been on library applications, but what he had in mind, mr. hammer said, was primarily on the basics of data processing, systems analysis, and other basic aspects that would be of interest to administrators. the intent would be to give administrators enough knowledge so that they could evaluate the results that they should be gaining from their data processing systems. these institutes would be a package deal in that the personnel and materials would be commercially supplied, dataflow has conducted seminars for the united states civil service commission. ibm has some seminars which are free, but there is a charge if they have to develop a special program. comment was made regarding seminars conducted several years ago where problems developed as to the commercial aspects. motion. it was moved by mrs. martin that the matter of !sad's cosponsoring basic data processing seminars with outside organizations be referred to the isad program planning committee for discussion and their evaluation. seconded by mr. fasana. carried. tuesday, january 22, 1974 the meeting was called to order by the president, mr. kilgour, at 2:25 p.m. those present were: board-frederick g. kilgour, lawrence w. s. auld, paul j. fasana, donald p. hammer (isad executive secretary), susan k. mqrtin, ralph m. shoffner, and berniece coulter, secretary, isad. guests-alex allain, brigitte kenney, ron miller, and velma veneziano. draft on ala goals and objectives. mrs. brigitte kenney sought feedback from the board on the paper previously distributed on the ala committee on planning's draft statement on ala's goals and objectives. several changes were suggested. mrs. kenney expressed her appreciation for their input. freedom to read foundation. mr. alex allain from the foundation presented the cause of the freedom to read foundation in rehighlights of meetings 47 gard to the current problem of censorship. he stressed the desire to keep channels open with the divisions of ala and with systems and networks across the nation. marbi and isad standards committee (tesla). velma veneziano, chairman of the marbi interdivisional committee, appeared before the isad board requesting clarification of the functions of marbi and the isad standards committee ( tesla). she said that her committee would like discrepancies cleared up and duplications eliminated. mrs. martin suggested that the charges to both marbi and tesla be reworded to clarify their functions. isad bylaws committee. in response to discussions concerning the establishment of several committees, mr. shoffner moved to establish an organization committee. seconded by mrs. martin. mr. fasana pointed out that the mechanism for establishing a bylaws committee was already spelled out in the isad constitution. the president can appoint the committee. motion withdrawn. mr. shoffner withdrew his motion. mr. fasana suggested that the bylaws committee also be charged with the organizational and review function. the matter of the standards committee's function was also made the charge of the bylaws committee. wednesday, january 23,1974 president kilgour called the meeting to order at 10:15 a.m. those present

vote of thanks to the nominating committee for their work. report of marc user's discussion group. mr. james rizzolo, chairman, said most of the discussion in the discussion group revolved around ala, clr, and the change in clr' s status which was moved in august from one irs classification to another. it is now an "op48 journal of library automation vol. 7/1 march 1974 erating foundation," i.e., it is active in programs rather than waiting for a reaction to a request using funds they have as a "carrot.'~ also discussed was whether clr should fund and pick the participants or clr should do the funding and ala pick the participants. , . also the group considered the question of standards and how one ardves at them. there are a number of groups in ala dealing with standards, but there is a need to work out a systematic method of developing standards. there needs to be a routine mechanism set up for going from an imtial formulation of an idea for a standard to a standard that the profession can live with. report of program planning committee.. the committee met at the asis meeting in los angeles prior to meeting at the ala midwinter meeting. . :rvir. brett butler, chairman, announced that three european librarians );lad been invited to participate in the 1974 annual program .at new york city. mr. kilgour was handling all arrangements. mr. kilgour informed the board that the travel expenses of all three librarians were ·being provided for by sources outside ala. linda crismond is the local planning person for the 1975. san francisco annual conference program which will be sponsored jointly with asis. joshua smith had suggested mark radwin of lockheed as liaison and he had agreed to serve in this capacity. . the new orleans institute on "alternatives in bibliographic networking" had enough registrants by midwinter to confirm it. there had been some difficulty concerning contact with speakers but the .details had been straightened out. copies of the program ·for the new orleans institute were distributed. mr. butler also inforrried the board that his committee was looking into the details of cooperating with other institutions and state schools which might be interested in working with isad in a seminar or institute. the committee was also considering what type of programs should ·be presented, subcontracting to outside companies, and how to control these. the members of the committee were working on a procedure manual for use in conducting institutes .. telecommunications committee report. the activities of the telecommunications committee are highly organizational at present. the committee has swung away from cable tv as its primary interest and towards telecommunications as applied to bibliographic networks. the chairman, david. waite, said there was a need to set up a simple guide to carry out their charge for the educational activities and legislation advisory responsibilities to the ala committee on legislation. more people would probably be appointed to the telecommunications committee as there was a need for more expertise to assign to the areas identified by the committee. . highlights of meetings 49 he further said that the need now is to determine what existing appara. tus may be utilized to fulfill the committee's responsibility to disseminate information regarding telecommunications as applied to the library community so that the committee could put most of .its effort into technical work. one project discussed was to gather background information on bibliographic data centers and network activities and their needs for telecommunication facilities in order to draft a requirements statement. the purpose of such a: statement is. that the committee could communicate .with new telecommunications systems. the committee was not aware of an ade· quate statement of library requirements that. is readily available ·for the commercial services that .are steadily increasing. assignments have been given to gordon randall, maryann duggan, and ron miller to gather this information. mtr. waite remarked that the committee would be interested in ~ny report on the proposed isad networks committee when available. brett. butler, chairman of the program planning co:rrnnittee; suggested that a telecommtmications institute should be in the future plans and mr. waite's or any of his committee members contribution of any ideas about· such would be appreciated. report 6f the interdivisional committee on machine-readable bibliographic information (marbi).

(see exhibit 5.) board minutes in lola. the board suggested that minutes published in ]ola be entitled "highlights of isad board meeting" rather than minutes. the meeting was adjourned at 12:30 p.m. exhibit 1 proposal for.establishing on a subscription basis a selective dissemination of information system for ala members the original proposal for an sdi system was intended for isad members only, but interest has grown at ala headqua1ters to the extent that it is being considered as a service to be provided for all ala members. the proposal therefore does not require any action on the part of the isad board. it is presented here for information and to give the board members an opportunity to comment on the idea and make suggestions toward developing the best possible procedure. it is hoped that a presently operating system can be found that would enable ala members to subscribe to a system using multisubject data banks that would automatically adjust profiles according to past output results and that would supply as requested copies of articles and documents whenever possible. such documents would of course be supplied at a fee additional to the basic subscription fee. it is also hoped that the operators of the system would be responsive to subscriber feedback and would improve the system as warranted. at present the only existing data banks in the library and information science fields are eric and marc, but hopefully as time goes on others will be developed. it, for example, would seem prudent for the h. w. wilson company to consider the sale of lihm1·y litemtme in machine-readable form. in any event, there is no reason to limit subscriptions to the service to information science data banks. if interested, members of ala could subscribe to other subject fields depending upon the data banks made available by the operating service. chemistry librarians could, if useful to them, subscribe to chemical abstmcts condensates, engineering librarians to enginee1'ing index, etc., etc. only time and the availability of sdi can determine the interest of librarians in such services. at the time of writing, only one of the two agencies contacted for information has provided descriptive data on their system. a copy of one of the papers sent by the ucla center for information services is attached. ohio state university libraries had not as yet responded. enquiries will be made with other operating systems so that a basis for comparison wiii be available for decision at ala headquarters. comments and suggestions from isad board members would be appreciated. information regarding presently operating systems would also be of great value. december 13, 1973 exhibit 2 reports of the meetings of the marbi committee (interdivisional committee on representation in machine readable form of bibliographic information) january 19 and 20, 1974 number one priority was the resolution of the relationship between the library of congress and marbi in its capacity as the marc advisory group. 52 journal of library automation vol. 7/1 march 1974 there was discussion of the position paper which was presented at the las vegas meeting (copy attached) entitled "the library of congress view on its relation to the ala marc advisory committee." lc had revised certain portions of this paper to conform with marbi's wishes. these revisions were acceptable to the committee. there was concern, however, over an addition which pertained to marbi's role with regard to formats other than books and serials (namely films, maps, music, etc.) alternate wording to lc's proposal was worked out by paul fasana and john knapp. several documents were submitted by henriette avram: (1) a proposed document numbering scheme for communications between lc and the committee and vice versa, and (2) proposed format for presenting changes to marc formats (copies attached). these documents and proposals were acceptable to the committee. (note: incidental to this discussion, the committee officially adopted "marbi" as its official acronym.) 1. the lc liaison presented two proposed marc format changes for the committee's consideration entitled: lc/marbi 2-addition of $x subfield for 4xx fields to allow for issn. lc/marbi 3-specincation of the 830 field. the committee decided that the following plan of action would be followed with regard to these two changes: they would be announced and distributed to isad marc users' discussion group at its january 21, 1974 meeting. the proposed changes would be sent to all on mudg's mailing list, asking for replies to the marbi chairman by february 16, 1974. the chairman would summarize responses and poll marbi committee members who would respond by march 16, 1974. the marbi committee chairman would respond to lc by march 16, 1974. marbi will request publication of changes in ]ola technical communications. 2. henriette avram presented to the committee a clr statement which had been presented to arl entitled "a composite effort to build an on-line national serials data base." the committee took note of the presentation with interest and voted to take no action on the matter at the january 19 meeting. 3. the character set subcommittee of marbi reported that it had issued a written report which will be used in support of the united states position concerning development of standards within the international standard organization. marbi issued thanks to the subcommittee and requested that they remain convened pending review of further developments coming from activities within iso. 4. there was a report on activities of the ad hoc committee convened by clr to discuss use of the marc format in a network environment. a paper entitled "sharing machine readable bibliographic data: a progress report on a series of meetings sponsored by the council on library resources" was discussed. the committee took note of these activities with interest and will wait for formal submission of format changes from the library of congress. 5. marbi discussed the apparent overlap of the change between marbi and the new isad committee on technical standards. marbi passed a resolution that the isad representatives should bring to the attention of the isad board its concern over the similarity of the function statements of the two committees, and asked that these apparent discrepancies be considered and any duplication be eliminated. 6. the proposed marbi serials task force was discussed. it was felt that marbi committee members needed to keep up on developments, and that the chairman should continue to collect and distribute as much documentation as possible to the committee highlights of meetings 53 members. it was decided that there was no need ~tt this time to set up a separate subcommittee to perform this function. 7. the proposed amendments to iso 2709-1973(e) were discussed. it appears that there are several proposals circulating to change this standard. marbi formed a subcommittee to study these proposals and respond, and possibly, to make counterproposals. the position of marbi will be reported to the chairman of ansi z-39, sc/2 and will be used in support of the u.s. position within iso. any committee member or interested professional may reply individually. the subcommittee appointed consists of charles payne, john knapp, mike malinconico, and charles husbands. response will be made by april 1, 197 4. at its regular scheduled meeting, on january 20, all members were present. (john byrum was unable to attend the unofficial meeting on january 19.) the distribution of the rtsd and isad manual material was discussed. the discussion of the previous day was summarized for purposes of review and for the benefit of the nonmembers attending the meeting. 1. marbi and lc the alternative wording to the lc position paper was presented by paul fasana. it was passed. henriette avram will have it published in lcib and will submit it to lola tc. lrts will also receive a copy. the paper will be submitted to each divisional board. 2. the national on-line union file of serials was discussed. larry livingston answered questions. 3. the character set subcommittee report will see that isad has a copy. interested professionals should ask for a copy from them. 4. the activities of the ad hoc clr committee were again reviewed. 5. the isad standards committee was discussed. 6. the serials task force for marbi was reported on. 7. the proposed changes to iso 2709-1973 (e) were reviewed. new business: 8. the activity of the ifla working group on content designators was discussed. it was reported that there is an attempt to standardize content designators across national boundaries, for purposes of international exchange. there are problems in the area of cataloging rules, not all libraries participating, and language. no action was needed, as this is only for informational purposes at this time. 9. location codes were discussed, but the issue was tabled pending report of ad hoc clr committee. 10. language and geographic area codes were brought up but not considered necessary to become involved. 11. the z39 standard account number (san) was reported by emery koltay. 12. progress in regard to the publication of the isbd-m and s was discussed. exhibit 3 cola report-midwinter '74 about fifty people were in attendance at portions of the four-hour meeting. the first half was taken up by a series of informal presentations about activity at: by: stanford

mike malinconico charles payne rob mcgee mary kay daniels questions were entertained at the end of each presentation. the second half was opened by a few announcements by maryann duggan about the new orleans institute and henriette avram about the serials proposals. the major portion of the second half consisted of a panel discussion by john kountz, eme1y koltay, tom brady, and john knapp on the communication of orders, claim reports, ill requests and responses in machine-readable form. john kountz addressed general system design aspects, emery koltay discussed the isbn, issn, and standard account numbers, tom brady discussed b&t's experiences with batab, and john knapp addressed the nature of the data elements and the record structure itself. considerable discussion followed the presentations, centering heavily on the isbn and its good points and failings. both parts of the meeting seemed to be well received. the major value of cola seems to be as an occasion for a wide variety of automation-oriented people to discuss a similarly wide variety of topics in an informal environment. there was some feeling that the presentations in the first half could have been more tightly controlled. the presentation in the second half was quite useful, i feel. i would like to suggest cola as a good sounding-board for proposals and place for announcements, distributions of handouts or written position papers. john kountz and i have discussed setting aside a portion of it for tesla reports. exhibit 4 respectfully submitted, brian aveney to: board of directors, information science and automation division from: john kountz, chairman, committee on technical standards for library automation subject: report of committee's activities, ala midwinter meeting, 1974 the committee on technical standards for library automation (tesla) held its inaugural meetings on tuesday, january 1974 (4:3d-6:00 p.m. and 8:30-11:00 p.m.). these were icebreaker meetings for a new group. in view of the interest that had been expressed in various quarters, several interested observers attended, as well as six of the seven committee members (for membership attendance see attached list). in addition, the following individuals were invited to meet with the committee and present their review of standards activities in other areas; establish a working perspective for the committee within the american library association; and delineate the constraints of the committee's charge: mr. fred kilgour, mr. don hammer, ms. velma veneziano, mr. emery koltay. while the specific discussion that ensued covered a variety of topics, the central objectives for these two meetings (establishing/ defining action areas, constraints, roles, and reviewing in some detail the committee's charge) were met. in addition, stress was placed throughout the discussion on differentiating between professional, service, bibliographic, and similar library standards, and the communications/ clearinghouse function to be served by the committee in its dealings with technical standards impacting library automation. highlights of meetings 55 at its next meeting, the committee can be expected to complete its deliberations on the charge, complete a proposed pilot procedure for the handling of initiative/reactive requirements for standards, and recommend a shakedown of the proposed procedure. committee

being coded now by my graduate assistant, and the university of south carolina computer centre will keypunch them for us. i am hopeful that we can start analyzing the results by the end of february, and have the report ready for you by april. the expenses to date have been: $346.95 164.32 166.60 $677.88 preliminary mailing printing of envelopes return postage the bill for printing the questionnaire hasn't been received yet but should be a very minor one. jim williams will write the program for the data, and the library school has computer time which we can use. i expect when all the expenses are in that the total will be more than the budgeted $700, but not very much more. submitted by: elspeth pope, chairman jim williams bill summers martha manheimer letter from the editor kenneth j. varnum information technology and libraries | march 2018 1 https://doi.org/10.6017/ital.v37i1.10388 this issue marks 50 years of information technology and libraries. the scope and everaccelerating pace of technological change over the five decades since journal of library automation was launched in 1968 mirrors what the world at large has experienced. from “automating” existing services and functions a half century ago, libraries are now using technology to rethink, recreate, and reinvent services — often in areas that simply were in the realm of science fiction. in an attempt to put today’s technology landscape in context, ital will publish a series of essays this year, each focusing on the highlights of a decade. in this issue, editorial board member mark cyzyk talks about selected articles from the first two volumes of the journal. in the remaining issues this year, we’ll tackle the 1970s, 1980s, 1990s, and 2000s. the journal itself, now as ever before, focuses on the present and the near future, so we will hold off recapitulating the current decade until our centennial celebration in 2068. as we look back over the journal’s history, the editorial board is also looking to the future. we want to make sure that we know for whom we are publishing these articles, and to make sure that the journal is as relevant to today’s (and tomorrow’s) readership as it has been for those who have brought us to the present. to that end, we invite anyone who is reading this issue to take this brief survey — tell us a little about how you came to ital today, how you’re connected with library technology, and what you’d like to see in the journal. it won’t take much of you r time (no more than 5 minutes) and will help us understand the context in which we are working. there’s another opportunity for you to help shape the future of the journal. due to a number of terms being up at the end of june 2018, we have at least five openings on the editorial board to fill. if you are passionate about libraries and technology, enjoy working with authors to shape their articles, and want to help set out today’s scholarly record for tomorrow’s technologists, submit a statement of interest at https://goo.gl/forms/5gbqouuseolxrfx52. we seek to have an editorial board that represents the diversity of library technology practitioners, and particularly invite individuals from non-academic libraries and underrepresented demographic groups to apply. sincerely, kenneth j. varnum editor march 2018

reflections of a first-year college library director ed tallent information technology and libraries | december 2012 3 as i reflect on my first year as director for a small college library, several themes are clear to me, but perhaps none resonates as vibrantly as the challenges in managing technology, technology planning, and the never-ending need for technology integration, both within the library and the college. it is all-encompassing, involving every library activity and initiative. while my issues will naturally have a contextual flavor unique to my place of employment, i imagine they reflect issues that all librarians face (or have already faced). what is perhaps less unique is how these issues of library technology intersect with some very high priority college initiatives and challenges. and, given myriad reports on students’ ongoing ambivalent attitudes toward libraries (after everything we have done for them!), it still behooves us to keep working at this integration of the library into the learning and teaching process and to hitch our wagon to larger strategic missions. so, what issues have i faced? the campus portal vs. library web site: this issue is neither new nor unique, but is still is a tangled web of conflicting priorities and attitudes, campus politics and technology vision, the extent and location of technology support, and the flexibility of the campus portal or content management system (cms) and the people who direct it. it is not a question of any misunderstandings, as the need to market the library via the campus web site is obvious and the goal of personalized service is laudatory. yet, marrying the external marketing needs with the internal support needs is a difficult balance to achieve. the web offers a more dramatic entrée to the library than a portal/intranet, and portal technology is not perfect, as jacob neilson highlights in a recent post. the goal obviously is further complicated by the fact that the support needed to maintain a quality web presence--one that is well graphically interesting, vibrant and intuitive--is significant when one considers library web sites are rarely used a place to begin research by students and faculty. ed tallent (edtallent@ curry.edu) is director, levin library, curry college, milton, massachusetts. http://www.useit.com/alertbox/intranet-usability.html editorial board thoughts: technology and mission | tallent 4 the portal, on the other hand, promises a personalized approach and easier maintenance, but lacks the level of operability that would be desirable. the web presence can support both user needs and offer visitors a sense of the quality services and collections the library provides. so, at this writing, what we have is a litany of questions not yet resolved. mobile, tablets, and virtual services: the questions also abound in these areas. should we build our own mobile services, or contract out the development? do we (can we) focus on creating a leadership role for the library in the area of emerging technology, or wait for a coordinated institutional vision and plan to emerge? in the area of tablets, we are about to commence circulating ipads and anyone who has gone through the labyrinthian process just to load apps will know that the process gives one pause as to the value of such an initiative, and that is before they circulate and need to be managed. still, it is a technology initiative that demands review of library work flows, security, student training, and collection access. virtual services were at a fairly nascent state upon my arrival and have grown slowly, as they are being developed in a culture that stressed individual, hands-on, and personalized services. virtual services can be all that, but that needs to be demonstrated not only to the user but to the people delivering the service. the added value here is that the work engages us in valuable reflections on the way in which we work or should work. value of the library: i began my new position at time when the college was deeply engrossed in the issue of student recruitment, retention, and success. for my employer these are significant institutional identity issues, and the library is expected to document its contributions to student outcomes and success. not nearly enough has been done, though a working relationship with a new director of institutional research is developing and critical issues such information literacy, integrated student support, learning spaces, learning analytics, and the need for a data warehouse will be incorporated into the into the college’s strategic plan. the opportunity is there for the library to link with major college initiatives, for example, and make information literacy more than a library issue. citation management: now, here is a traditional library activity, the bane of many a reference service interaction and the undergraduate’s last-minute nightmare. a combination of technical, service and fiscal challenge revolve around the campus climate on the use of technology to respond to this quandary. what to do with faculty who believe strongly that the best way to learn this skill is by hand, not with any system that aims for interoperability and a desire to save the time of the user? for others, which tool should be used? should we not just go with a free one? while discipline differences will always exist, the current environment does present opportunities for the library to take a leadership role in defining what the possibilities are and ideally connecting the approach to appropriate and measurable learning outcomes and to the larger issue of academic integrity. information technology and libraries | december 2012 5 e-books, pda, article tokens: one of the unforeseen benefits of my moving to a small college library is that there is not the attachment to a print collection that exists in many/most research libraries. there is remarkable openness to experimenting with and committing to various methods of digital delivery of content. thus, we have been able to test myriad possibilities, from patron driven book purchasing, tokens for journal articles, and streaming popular films from a link in the library management system. this blurring of content, delivery, and functionality presents numerous opportunities for librarians to have conversations with departments of the future of collections. connecting with alumni: this is always an important strategic issue for colleges and universities and it seems as though there are promising emerging options for libraries to deliver database content to alumni, as vendors are beginning to offer more reasonable alumni-oriented packages. my library will be working with the appropriate campus offices next year to develop a plan for funding targeted library content for alumni as part of the college’s broader strategic activities to engage alumni. web design skills: while i understand the value that products like libguides can bring to the community, allowing content experts (librarians) to quickly and easily create template-driven web-based subject guides, i remain troubled by the lack of design skills librarians possess, and by the lack of recognition that good design can be just as important as good content. this is not a criticism, as we are not graphic designers. we have a sense of user needs, knowledge about content, and a desire to deliver, but i believe that products like this lead librarians to believe that good design for learning is easy. i do not claim to be an expert, but i know this is not the case. this approach does not translate into user friendly guides that hold to consistent standards. i think we need to recognize that we can benefit from non-librarian expertise in the area of web design. one opportunity that i want to investigate along these lines is to create student internships that would bring design skills and the student perspective to the work. a win-win, as this also supports the college’s desire for more internships and experiential learning for students. there is neither time nor space to address an even broader library technology issue on the near horizon, which will be another campus engagement moment, the future ils for the library. yet, maybe that should have been addressed first, since what i have read and heard, the new ilss will solve all of the above problems! metadata provenance and vulnerability timothy robert hart and denise de vries information technology and libraries | december

pace of technological change makes accessing these media increasingly difficult. digital preservation is primarily accomplished by main methods, migration and emulation. migration has been proven to be a lossy method for many types of digital objects. emulation is much more complex; however, it allows preserved digital objects to be rendered in their original format, which is especially important for complex types such as those comprising multiple dynamic files. both methods rely on good metadata to maintain change history or construct an accurate representation of the required system environment. in this paper, we present our findings that show the vulnerability of metadata and how easily they can be lost and corrupted by everyday use. furthermore, this paper aspires to raise awareness and to emphasise the necessity of caution and expertise when handling digital data by highlighting the importance of provenance metadata. introduction unesco recognised digital heritage in its “charter on the preservation of digital heritage,” adopted in 2003, stating, “the digital heritage consists of unique resources of human knowledge and expression. it embraces cultural, educational, scientific and administrative resources, as well as technical, legal, medical and other kinds of information created digitally, or converted into digital form from existing analogue resources. where resources are ‘born digital’, there is no other format but the digital object.” 1 born-digital objects are at risk of degradation, corruption, loss of data, and becoming inaccessible. we combat this through digital preservation to ensure they remain accessible and useable. the two main approaches to preservation are migration and emulation. migration involves migrating digital objects to a different and currently supported file type. emulation involves replicating a digital environment in which the digital object can be accessed in its original format. both methods have advantages and disadvantages. migration is the more common method because it is simpler than emulation and the risks can often be neglected. these risks include potential data loss or change, in which the effects are permanent. emulation is complex, but it offers the better means to access preserved objects, especially complex file types comprising multiple dynamic files that must be constructed correctly. emulation also allows users to handle digital objects as closely to the “look and feel” as originally intended. 2 mailto:tim.hart@flinders.edu.au mailto:denise.devries@flinders.edu.au metadata provenance and vulnerability | hart and de vries 25 https://doi.org/10.6017/ital.v36i4.10146 accurate and complete metadata is central to both migration and emulation; thus, it is the focus of this paper. metadata are needed to record the migration history of a digital object and to record contextual information. they are also necessary to accurately render digital objects in emulated environments. emulated environments are designed around a digital object’s dependencies , which typically include, but are not limited to, drivers, software, and hardware. 3 the metadata describe the attributes of the digital object from which we can derive the type of system in which it can run (e.g., the operating system), the versions of any software dependencies, and other criteria that are crucial for accurate creation of an emulated environment. while metadata are being used to support the preservation of digital objects, there is another equally important role it should be playing. it is not enough to preserve the object so it can be accessed and used in the future. what of the history and provenance of the digital object? what about search and retrieval functionality within the archive or repository the digital object is held in? one must consider how these preserved objects will be used in the future, and by whom. preserving digital objects is difficult if adequate metadata is not present, especially if the item is outdated and no longer supported. looking to the future, we should try to ensure metadata are processed correctly for the lifecycle of the digital object. this means care must be taken at the time of creation and curation of any digital objects because although some metadata are typically generated automatically, many elements that will play a pivotal role later must be created manually. digital objects also commonly go through many changes, which is something that must be captured, as the change history will reveal what has happened to the object over of its lifecycle. the changes may include how the object has been modified, migrations to different formats, and what software created or changed the object—all of which is considered when emulating an appropriate environment. examples of these changes can be found in case studies presented in the paper. metadata types the common and more widely used metadata types include, but are not restricted to, administrative, descriptive, structural, technical, transformative, and preservation metadata. each metadata type describes a unique set of characteristics for digital objects. administrative metadata include information on permissions as well as how and when an object was created. transformative metadata includes logs of events that have led to changes to a digital object. 4 structural metadata describe the internal structure of an object and any relationships between components. technical metadata describe the digital object with attributes such as height, weight, format, and other technical details. 5 preservation metadata support digital preservation by maintaining authenticity, identity, renderability, understandability, and viability. they are not bound to any one category as they comprise multiple types of metadata, not including descriptive or contextual metadata. however, unlike the common metadata types, preservation metadata are unique from the other metadata types and are often ambiguous. 6 in 2012, the developers of version 2.2 of the premis data dictionary for preservation metadata saw descriptive metadata as less crucial for preserving digital objects; however, they did state it was important for discovery and decision making. 7 while version 2.2 allowed descriptive information technology and libraries | december 2017 26 metadata to be handled externally through existing standards such as dublin core, the latest version (2017) of the dictionary allows for “intellectual entities” to be created within premis that can capture descriptive metadata. 8 thus, while digital preservation does not require all types of metadata, the absence of contextual metadata limits the future possibilities for the preserved object. hart writes that because the multimedia objects are dynamic and interactive, and often composed of multiple image, audio, video, and software files, descriptive metadata are increasingly important because they can be used to describe, organise, and package the files. 9 it is also stressed that content description is of great importance because digital objects are not self-describing, which makes identifying semantic-level content difficult; without description metadata, context is lost. 10 for example, without description metadata to provide context, an image’s subject information and search and retrieval functionality is lost. without this information, verifying whether an object is the original, a copy, or a fabricated or fraudulent item is impossible in most cases. metadata vulnerability—case studies digital objects that are currently being created often go through several modifications, making it difficult to identify the original or authentic copy of the object. verifying and validating authenticity is important for preserving, conserving, and archiving objects. the digital preservation coalition defines authenticity as the digital material is what it purports to be. in the case of electronic records, it refers to the trustworthiness of the electronic record as a record. in the case of “born digital” and digitised materials, it refers to the fact that whatever is being cited is the same as it was when it was first created unless the accompanying metadata indicates any changes. confidence in the authenticity of digital materials over time is particularly crucial owing to the ease with which alterations can be made. 11 tests were undertaken to discover how vulnerable metadata can be in digital files that are subject to change, which can lead to loss, addition, and modification. the tests were conducted using the file types jpeg, pdf, and docx (word 2007). the tests revealed what metadata can be extracted and what metadata could be present in the selected file types. furthermore, they revealed how specific metadata can verify and validate the authenticity of a file such as an image. for each test, the metadata were extracted using exiftool (http://owl.phy.queensu.ca/~phil/exiftool/). alternative browser-based tools were tested and provided similar results; however, exiftool was selected as the primary testing tool because it produced the best results and had the best functionality. some of the files tested provided extensive sets of metadata that are too large to include, but subsets can be found in hart (2009). note that only subsets are included because some metadata was removed for privacy and relevance reasons. the process and method for each test was conducted in the following manner: http://owl.phy.queensu.ca/~phil/exiftool/ metadata provenance and vulnerability | hart and de vries 27 https://doi.org/10.6017/ital.v36i4.10146 • case study 1—jpeg o original metadata extracted for comparison o image copied, metadata extracted from copy and examined for changes o file uploaded to social media, downloaded from social media, extracted and examined against original • case study 2—jpeg (modified) o original metadata extracted for comparison o image opened and modified in photo editing software (adobe photoshop), metadata extracted from new version and examined against original • case study 3—pdf o basic metadata extraction performed to establish what metadata are typically found in pdf files and what types of metadata could be possible • case study 4—docx o original metadata extracted for comparison o file saved as pdf through microsoft word and metadata compared to original o file converted to pdf through adobe acrobat and metadata compared to original case study 1 this case study investigated the everyday use of digital files, the first being simply copying a file. it was revealed that copying a file creates an exact copy of the original file and no changes in metadata aside from the creation and modification time/date. thus, the copy could not be identified against the original unless the original creation time/date was known. the second everyday use was uploading an image to facebook. the metadata-extraction tests revealed that the original file had approximately 265 metadata elements. (the approximation is caused by the ambiguity of certain elements that may be read as singular or multiple entries.) these elements included, but were not limited to, the following: • dates • technical metadata • creator/author information • color data • image attributes • creation-tool information • camera data • change • software history many of the metadata elements had useful information for a range of situations. even so, several metadata elements were missing that would require a user input for creation. once the file had been uploaded to and then downloaded from social media, approximately 203 metadata elements were lost, included date, color, creation-tool information, camera data, change, and software history. it can be argued that removing some of this metadata would help keep user information private, but certain metadata should be retained, such as change and software history. these information technology and libraries | december 2017 28 metadata make it easier to differentiate fabricated images from authentic images and to know which modifications have been made to a file. for preservation purposes, the missing metadata is what may be needed to provide authenticity. this case study aims to make users aware of the significant risk of metadata loss when dealing with digital objects. if metadata are not identified and captured before the object is processed within a repository, the loss could be irreversible. case study 2 the second case study revealed how the change and software history metadata can be used to easily identify when a file has been modified. in the test conducted, it was evident by visually comparing the images that changes were made; however, modifications are not always obvious as some changes can be subtle, such as moving an element in the image that completely changes what the image is conveying. the following example displays the change history from the image used in case study 1, revealing how the metadata can easily identify modification: • history action—saved, saved, saved, saved, converted, derived, saved • history when—the first saved was at 2010:02:11 21:59:05, the last saved was at 2010:02:11 22:12:01 with each action having its own timestamp • history software agent—adobe photoshop cs4 windows for each action • history parameters—converted from tiff to jpeg further testing was conducted with simple photo manipulation using an original image to see firsthand the issues described in the initial test. the image contained approximately 178 metadata elements, including the typical metadata that were found in the first case study. once the image was processed and modified with adobe photoshop cs5, the metadata were no longer identical. the modified image had approximately 201 metadata elements. the new elements included photoshop-specific data, change, and software history. however, extensive camera data were lost. it can be argued that the camera data are not important for digital preservation because the lack of it will not hinder the preservation process. however, once the file is preserved and those data are lost, important technical and descriptive information can never be regained. for example, consider a spectacular digital image that captures an important moment in history. if that image is preserved for twenty years, in that time cameras and perhaps photography itself will have advanced dramatically. how digital images are captured and processed might be completely different and will most likely provide different results. should someone wish to know how that preserved image was captured, they would need to know what camera was used, lens and shutter speed data, lighting data, and other technical information. preserving those metadata can be almost as important as preserving the file itself because each metadata element has importance and meaning to someone. as most viewers of online media are aware, photos are often modified, especially on social media. this is often performed on “selfies,” pictures taken of oneself. these can be modified to make the person in the photo look better or to hide features they see as flawed. small modifications, such as covering some blemishes or improving the lighting have little effect on the image’s context, but some modifications and manipulations that can mislead people. these manipulated images often metadata provenance and vulnerability | hart and de vries 29 https://doi.org/10.6017/ital.v36i4.10146 take the form of viral hoax images circulating around the web. for example, figure 1 displays how two images can be combined into a composite image that changes the context of the image. figure 1. composite image. “photo tampering throughout history,” fourandsix technologies, 2003, http://pth.izitru.com/2003_04_00.html. the two images side by side are original photos taken in basra of a british soldier gesturing to iraqi civilians to take cover. in the right image, the iraqi man is holding a child and seeking help from the solider; as you can see, this soldier does not interpret this as a hostile act. the image above is a composite of the two that changes the story. in this image, the soldier appears to be responding with hostility toward the man approaching. with basic photo manipulation, this soldier who is protecting innocent civilians is portrayed holding them against their will. images like this circulate through media of all types, and although the exchangeable image file format (exif) metadata may not identify what has been done to the image, it would eliminate any doubt that the image has been modified. unfortunately, these data are not made available. making users aware of this vulnerability may improve detection of file manipulation at the time of ingest to better ensure only accurate and authentic material is being considered for preservation. donations received by digital repositories such as libraries must be scrutinised by trained individuals. with this awareness and knowledge of metadata, they can perform their duties to a much higher standard. case study 3 the pdf metadata extraction provided interesting results. over a range of tests on academic research papers, the main metadata identified consisted of pdf version, author, creator, creation date, modification date, and xmp (adobe extensible metadata platform) data. these metadata http://pth.izitru.com/2003_04_00.html information technology and libraries | december 2017 30 were not present in every pdf tested; in fact, the majority of pdf files seemed to be lacking important metadata. the author and creator fields were generally listed as “administrator” or “user” and bibliographic metadata was usually missing. however, pdf openly supports xmp embedding, therefore, bibliographic metadata could be embedded into the pdf. through further testing, bibliographic metadata linked to the pdfs were discovered stored in online databases. bibliographic software such as endnote and zotero allow metadata extraction, which enables users to import pdf files and automatically generate the appropriate bibliographic metadata. for example, zotero performs this extraction by first searching for a match for the pdf on google scholar. if this search does not return a match, zotero uses the embedded digital object identifier (doi) to perform the match. this method is not consistent: it often fails to retrieve any data, and in rare cases it retrieves the wrong data, which leads to incorrect references. given what we saw happen to metadata when a file is uploaded such as in case study 1 and the nature of a pdf’s journey through template selection, editing, and publishing, it is no surprise that metadata are lost or diluted along the way. case study 4 the fourth case study conducted on docx files provided an extensive set of metadata, some of which are unique to this file type. creating a new word document via the file explorer context menu and attempting to extract metadata resulted in an error as there were no readable metadata to extract until the file was accessed and saved. once the file had some user input and was saved, the metadata were created and could be extracted. microsoft office files contain external xml files that holds information about the document, such as formatting data, user information, edit history, and information about the document’s page count, word count, etc. picture a docx file as an uncompressed directory. however, using exiftool on the docx file allowed retrieval of the metadata from all the hidden files. the metadata included creation, modification, and edit information, such as number of edits and total edit time. every element within the document (e.g., text, images, tables, etc.) has its own metadata attached that are crucial for preserving the format of the document. the next step in the test involved converting the docx file into pdf using the following two methods: (1) converting the document via the “publish” save option within microsoft word; and (2) “right clicking” the document and selecting the option to convert to an adobe pdf. the results of the two methods varied slightly. method 1 stripped all the metadata from the document and generated only default pdf metadata consisting of system metadata (file size, date, time, permissions) and the pdf version, author details, and document details. method two behaved the same way except that some xmp metadata were created. both methods resulted in no informative metadata remaining as the majority of the xmp elements were empty fields or contained generic values such as the computer name as the author. all formatting and metadata unique to microsoft word was lost. this case study is an enlightening example of what can happen to metadata when a file is changed from one format to another. metadata provenance and vulnerability | hart and de vries 31 https://doi.org/10.6017/ital.v36i4.10146 human intervention the human element is a requirement in digital preservation as certain metadata, such as descriptive and administrative metadata, can only be created by humans. in fact, as hart notes, user input is needed to record the majority of the digital preservation metadata. 12 the process can be tedious, as described by wheatley. 13 one of the examples described included following the processes in a repository from ingest to access, beginning with the creation of metadata and the managerial tasks that are necessary. these tasks include using extraction tools and automation where possible. using frameworks to record changes to metadata is required, and in some cases metadata must be stored externally to their digital objects. this allows multiple objects of the same type to utilise a generic set of metadata to avoid redundant data. however, although using a generic metadata set is convenient, a large collection of digital objects could be affected if the metadata is lost or damaged. the human element increases the risk of error drastically because there are numerous steps to metadata creation. misconduct is also possible. therefore, the less digital preservation is reliant on humans (and the easier the tasks are that require human input), the better. this can only be achieved by automating most process and training people to ensure they handle their responsibilities accurately, consistently, and completely. learning the results from the case studies like those described in this paper will better prepare users working with digital objects. discussion to achieve the most authentic, consistent, and complete digital preservation, institutions must revise their preservation workflows and processes. this entails ensuring the initial processes within workflows are correct before processing digital content. the content must come from a credible source and have its authenticity approved. participation from the donor of the digital content might be beneficial if they can provide information and metadata about the content. this information could provide additional context for the content as well as identify its history (e.g., format migration or modification). this is not always possible as the donor is not always be the creator of the digital content. if the original source is no longer available, as much information as possible should be gathered from the donor about the acquisition of the content and any information regarding the original source. this should be considered and carefully monitored throughout the lifecycle of digital content. granted, if no changes are needed, devices such as write blockers can ensure this as they restrict users and any systems from making unwanted changes or “writes.” however, changes are sometimes unavoidable and (although it may not affect the content) detrimental. when changes are required, it is crucial to maintain the digital history by capturing all metadata added, removed, or modified during processing, commonly known as the “change history.” donor participation should be stipulated in a donor agreement, something that each institution offers to all donors, sometimes in the form of agreements through communication and often with a structured document. donor-agreement policies differ for each institution: some are quite detailed, allowing donors to carefully stipulate their conditions, whereas others place most of the information technology and libraries | december 2017 32 responsibility on the receiving institution. when dealing with sensitive or historic data of importance, policies should be in place to capture adequate data from the donor. when the content does not fall into this category, standard procedures, which should be present in all donor agreements and institution policies, can be followed. institutions must also consider when to apply these steps as some transactions between donor and institution can follow standard protocol; others are more complex, such as donations of content with diverse provenance issues. conclusion we have presented four case studies that illustrate how vulnerable digital-object metadata are. these examples show that common methods of handling files can cause irretrievable loss of important information. we discovered significant loss of metadata when uploading photos to social media and when converting a file to another format. the digital footprint left behind from photo manipulation was also exposed. we shed light on the bibliographic-metadata generation of pdf files, how they are obtained, and the surrounding issues. action is needed to ensure proper metadata creation and preservation for born-digital objects. librarians and archivists must place a greater emphasis on why digital objects are preserved as well as how and when users may need to access them. therefore, all types of metadata must be captured to allow users from all disciplines to take advantage of historical data in many years to come. given the rate of technological change, we must be prepared; observing first-hand the vulnerability of metadata is a step toward a safer future for our digital history. references 1 “charter on the preservation of digital heritage,” unesco, october 15, 2003, http://portal.unesco.org/en/ev.phpurl_id=17721&url_do=do_topic&url_section=201.html. 2 k.

inhaled helmer, john f information technology and libraries; jun 2000; 19, 2; proquest pg. 59 editorial: i inhaled t his editorial introduces the third special issue of information technology and libraries dedicated to library consortia, and the second primarily aimed at surveying consortial activities outside the united states. 1 the concept of a special consortial issue began in 1997 as an outgrowth of a sporadic and wide-ranging discussion with jim kopp, editor of ital 1996-98. at the time, jim and i were involved in the creation and maturation of the orbis consortium in oregon and washington. jim was a member and later chair of the governing council and i was chief volunteer staff person and finding myself increasingly absorbed by consortial work. our discussions lasted more than a year and were sustained by many e-mail messages and several enjoyable conversations over bottles of nut brown ale. in the mid-1990s it seemed obvious that we were witnessing the beginning of a renaissance in library consortia. consortia had been around for many years but now established groups were showing renewed vigor and new groups seemed to be forming every day. why was this happening? what were all these consortia doing? jim and i discussed these questions and speculated on future roles for library consortia and their impact on member libraries. library consortia seemed an ideal topic for a special issue of ital. my initial goal as guest editor of ital was to take a snapshot of a variety of consortia and begin to better understand the implications of the explosive growth we were witnessing. while assembling the march 1998 issue i soon realized that consortia were all over the map, both figuratively and literally. a small amount of study revealed a tremendous variety of consortia and a truly worldwide distribution. although american consortia were starting to receive attention in the professional literature, a great deal of important work was occurring abroad. this realization gave rise to the september 1999 issue and the present issue dedicated to consortia from around the world. in addition to six articles from the united states, these three special issues of ital include contributions from south africa, canada, israel, spain, australia, brazil, john f. helmer china, italy, micronesia, and the united kingdom. taken together these groups represent a dizzying array of organizing principles, membership models, governance structures, and funding models. although most are geographically defined, the type of library they serve also defines many. virtually all license electronic resources for their membership but many offer a wide variety of other services including shared catalogs, union catalogs, patron-initiated borrowing systems, authentication systems, cooperative collection development, digitizing, instruction, preservation, courier systems, and shared human resources. each consortium is formed by unique political and cultural circumstances, but a few themes are common to all. it is clear that the technology of the web, the increasing importance of electronic resources, and advances in resource-sharing systems have created new opportunities for consortia. beyond these technological and economic motivations, i believe that in consortia we see the librarian's instinct for collaboration being brought to bear at a time of great uncertainty and rapid change. librarians often forget that as a profession we collaborate and cooperate with an ease seldom seen in other endeavors. there is safety in numbers and in uncertain times it helps to confer with others, spread risk over a larger group, and speak with a collective voice. library consortia fulfill these functions very well and their future continues to look bright. as i conclude my duties as guest editor i would like to thank jim kopp for sparking my interest in this project and for several years of stimulating conversation. special thanks are due

the editorial introduction to the first special consortial issue, i compared a librarian's involvement in consortia to the cameroonian stink ant's inhalation of a contagious spore. the effect of this spore is featured in mr. wilson's cabinet of wonder, lawrence weschler's remarkable history of the museum of jurassic technology. 2 weschler explains that, once inhaled, the spore lodges in the brain and "immediately begins to grow, quickly fomenting bizarre behavioral changes in its ant host." although the concept of a consortial spore is somewhat extreme (or "icky" according to my nine-yearold daughter) the editorial was an accurate reflection of my own sense of being inexorably drawn into a consortium-drawn not so much against my will but as a willing crazed participant. at the time i was nominally working for the university of oregon library system and vainly trying to keep consortial work in perspective. 60 information technology and libraries i june 2000 by the time of my second editorial, epidemiology of the consortia/ spore, i was exploring consortia around the world but still laboring under the illusion that i could keep my own consortium at arm's length. i must have failed since, as of this writing, i have left my position at the uo and now serve as the executive director of the orbis library consortium. like the cameroonian stink ant, i have inhaled the spore and am now happily laboring under its influence. references and notes 1. see ital 17, no. 1 (mar. 1998) and ital 18, no. 3 (sept. 1999). 2. lawrence weschler, mr. wilson's cabinet of wonder (new york:

masses: gis lite and online mapping tools in academic libraries kathleen w. weessies and daniel s. dotson information technology and libraries | march 2013 23 abstract customized maps depicting complex social data are much more prevalent today than in the past. not only in formal published outlets, interactive mapping tools make it easy to create and publish custom maps in both formal and more casual outlets such as social media. this article defines gis lite, describes three commercial products currently licensed by institutions, and discusses issues that arise from their varied functionality and license restrictions. introduction news outlets from newspapers to television to internet these days are filled with maps that make it possible for readers to visualize complex social data. presidential election results, employment rates, and the plethora of data arising from the census of population are just a small sampling of social data mapped and consumed daily. the sharp rise in published maps in recent years has increased consumer awareness of the effectiveness of presenting data in map format and has raised expectations for finding, making and using customized maps. not just in news media, but in academia also, researchers and students have high interest in being able to make and use maps in their work. just a few years ago even the simplest maps had to be custom made by specialists. researchers and publishers had to seek out highly trained experts to make maps on their behalf. as a result, custom maps were generally only to be found in formal publications. the situation has changed partly because geographic information system (gis) software for geographic analysis and map making is more readily available than in years past. it does, however, remain specialized and wants considerable training for users to be proficient at even a basic level.1 this gap between supply and demand has been partly filled, especially in the last five years, by the growth of internet-based “gis lite” tools. while some basic tools are freely available on the internet, several tools are subscription-based and are licensed by libraries, schools and businesses for use. college and university libraries especially are quickly becoming a major resource for data visualization and mapping tools. the aim of this article is to describe several data-rich

dissertation, etc.). if their research involves data analysis, geospatial tools will draw attention to spatial patterns in the data that might not otherwise be apparent. every scholar with such needs must make a cost/benefit decision concerning gis: is his or her need greater than the cost in time and effort (sometimes money) necessary to learn or hire skills to produce map products? a full functioning gis, being a specialized system of software designed to work with geospatially referenced datasets, is designed to address all the problems above. the data may be analyzed and output into customized maps exactly to the researcher’s need. the traditional lowend solution available to non-experts, on the other hand, is colorizing a blank outline map, either with hand-held tools (markers, colored pencils, etc.) or on a computer using a graphic editing program. the profusion of web mapping options dangles tantalizingly with possibility, and occasionally (and increasingly) is able to provide an output that illustrates a useful point of users’ research in a professional enough manner to fill a need. in recent years the web has blossomed with map applications collectively called the “geoweb” or “geospatial web.” geoweb or geospatial web refers to the “emerging distributed global gis, which is a widespread distributed collaboration of knowledge and discovery.”2 some geoweb applications are well known street map resources such as google maps and mapquest. others are designed to deliver data from an organization, such as the national hazards support system (http://nhss.cr.usgs.gov), national pipeline mapping system (http://www.npms.phmsa.dot.gov/publicviewer), and the broadband map (http://www.broadbandmap.gov). a few tools focus on map creation and output such as arcgis online (http://www.arcgis.com/home/webmap/viewer.html) and scribble maps (http://www.scribblemaps.com). the newest subgenre of the geoweb consists of participatory mapping sites such as openstreet map (http://www.openstreetmap.org), did you feel it? (http://earthquake.usgs.gov/earthquake.usgs.gov/earthquakes/dyfi), and ushahidi (http://community.ushahidi.com/deployments). the geoweb literature is small but growing. 3 elwood reviewed published research on the geographic web.4 the geoweb literature tends to focus on creation of mappable data and delivery of geoweb services.5 in these the map consumer only appears as a contributor of data. very little has been written about users’ needs from the geoweb. the term gis lite has arisen among map and gis librarians to describe a subset of geoweb applications. gis lite is useful to library patrons lacking specialized gis training but who wish to conduct some gis and map-making activities on a lower learning curve. for the purpose of this article, gis lite will refer to applications, usually web-based, which allow users to manipulate geospatial data and create map outputs without programming skills or training in full gis software. http://nhss.cr.usgs.gov/ http://www.npms.phmsa.dot.gov/publicviewer http://www.broadbandmap.gov/ http://www.arcgis.com/home/webmap/viewer.html http://www.scribblemaps.com/ http://www.openstreetmap.org/ http://earthquake.usgs.gov/earthquake.usgs.gov/earthquakes/dyfi http://community.ushahidi.com/deployments information technology and libraries | march 2013 25 while many geoweb applications allow only low-level output options, gis lite will provide an output intended to be used in activities or rolled into a gis for further geospatial processing. in libraries, gis lite is closely allied with data and statistics resources. data and statistics librarianship have already been discussed as disciplines in the literature such as by hogenboom6 and gray.7 new technologies and access to deeper data resources such as the ones presented here have raised the bar for librarians’ responsibilities for curating, serving, and aiding patrons in its use. rather than be passive shepherds of information resources, librarians are now active participants and even information partners. librarians with map and gis skills similarly can directly enhance the quality of student scholarship across academic disciplines.8 the gis lite resources, however, need not remain specialized tools of map and gis librarians. librarians working in disciplines across the academic spectrum may incorporate them into their arsenal of tools to meet patron needs. data visualization tools a growing number of academic libraries have licensed access to online data providers. the following data tools contain enough gis lite functionality to aid patrons in visualizing and manipulating data (primarily social data) and creating customized map outputs. three of the more powerful commercial products described here are social explorer, simplymap, and proquest statistical datasets. social explorer licensed by oxford university press, social explorer provides selected data from the us decennial census 1790 to 2010, plus american community survey 2006 through 2010.9 the interface enables either retrieval of tabular data or visualization of data in an interactive map. as the user selects options through pull-down menus, the map automatically refreshes to reflect the chosen year and population statistics. the level of geography depicted defaults to county level data. if a user zooms in to an area smaller than a county, then data refreshes to smaller geographies such as census tracts if they are available at that level for that year. output is in the form of graphic files suitable for sharing in a computer presentation (see figure 1). one advantage of social explorer is that it utilizes historic boundaries as they existed for states, territories, counties, and census tracts for each given year. social explorer utilizes data and boundary files generated by the national historical gis (nhgis) based at the university of minnesota in collaboration with other partners. the creation of these historical boundaries was a significant undertaking and accomplishment.10 custom tables of data and the historic geographic boundaries may also be retrieved and downloaded for use from an affiliated engine through the nhgis website (http://www.nhgis.org). a disadvantage of this product is that the tool, while robust, does not completely replicate all the data available in the original paper census volumes. also, historical boundaries have not been created for city or township-level data. the final map layout is not customizable either in the location of title and legend or in the data intervals. http://www.nhgis.org/ mapping for the masses: gis lite & online mapping tools in academic libraries | weessies and dotson 26 figure 1: map depicting population having four or more years of college, 1960 (source: social explorer, 2012; image used with permission) simplymap simplymap (http://geographicresearch.com/simplymap) is a product of geographic research. this powerful interface brings together public and licensed proprietary data to offer a broad array of 75,000 data variables in the united states. us census data are available 1980–2010 normalized to the user’s choice of either year 2000 or year 2010 geographies. numerous other licensed datasets primarily focus on demographics and consumer behavior, which makes it popular as a marketing research tool. each user establishes a personal login which allows created maps and tables to persist from session to session. upon creating a map view, the user may adjust the smaller geographic unit at which the theme data is displayed and also may adjust the data intervals as desired. the user creates a layout, adjusting the location of the map legend and title before exporting as a graphic or pdf (see figure 2). data are also exportable as gis-friendly shapefiles. http://geographicresearch.com/simplymap information technology and libraries | march 2013 27 the great advantage of this product is the ability to customize the data intervals. this makes it possible to filter the data and display specific thresholds meaningful to the user. for instance if a user needs to illustrate places where an activity or characteristic is shared by “over half” of the population, then one may change the map to display two data categories: one for places where up to 50 percent of the population shares the characteristic and a second category for places where more than 50 percent of the population shares the characteristic. another potential advantage is that all local data have been allocated pro rata so that all variables, regardless of their original granularity, may be expressed by county boundaries, by zip code boundaries, or by census tract. a disadvantage of the product is the lack of historical boundaries to match historical data. figure 2. map depicting census tracts that have more than 50% black population (yellow line indicates cincinnati city boundary) (source: simplymap, 2012; image used with permission) mapping for the masses: gis lite & online mapping tools in academic libraries | weessies and dotson 28 proquest statistical datasets statistical datasets was developed by conquest systems inc. and is licensed by proquest. this product also mingles a broad array of several thousand public and licensed proprietary datasets, including some international data, in one interface. the user may retrieve data and view it in tabular or chart form. if the data have a geographic element, then the user may switch the view to a map interface. the resulting map may be exported as an image. the data may also be exported to a gis-friendly shapefile format. this product offers more robust data manipulation than the other products, in that the user may perform calculations between any of the data tables and create a chart or map of the created data element (see figure 3). statistical datasets, however, has more simplistic map layout capabilities than the other products. figure 3. map of sorghum production, by country, in 2010 (source: proquest statistical datasets, 2012; image used with permission) case studies the following three case studies are of college classroom situations in which students utilized maps or map making as part of the assigned course work. the above mapping options are assessed for how well they met the assignment needs. information technology and libraries | march 2013 29 case study 1 an upper level statistics course at the ohio state university requires students to create maps using sas (http://www.sas.com). while many may not associate the veteran statistical software package with creating maps, this course uses it along with sas/graph to combine statistical data with a map. the project requires data articulated at the county level in ohio, which the students then combine into multi-county regions. the end result is a map with regions labeled and rendered in 3d according to the data values. an example of the type of map that could be produced from such data using sas can be seen in figure 4. figure 4. map of observed rabbit density in ohio using sas, sas/graph, and mail carrier survey data,1998 (image used with permission) while the data are provided in this course, students could potentially seek help from the library in a traditional way to find numerical data expressed at a county level. the librarian would guide http://www.sas.com/ mapping for the masses: gis lite & online mapping tools in academic libraries | weessies and dotson 30 patrons through appropriate avenues to locate data such as to the three products listed above. all three options contain numerous data variables for ohio at the county level. because the students are further processing the data elsewhere (in this case sas), the output options of the three products are less important. ultimately the availability of data on a desired subject would be the primary determinant for choosing one of the three gis lite options discussed here. social explorer will export the data in tabular form which can then be ingested into sas. simplymap and proquest statistical datasets would both be a bit easier, though, because both packages allow the user to export the data as shapefiles which are directly imported into sas/graph as both boundary files and joined tabular data. case study 2 a first year writing class at michigan state university has a theme of the american ethnic and racial experience. assignments all relate to a student’s chosen ethnic group and geographic location from approximately 1880 to 1930. assignments build upon each other to culminate in a final semester paper. students with ancestors living in the united states at that time are encouraged to examine their own family’s ethnicity and how they fit in their geographic context. otherwise, students may choose any ethnic group and place of interest. maps are a required element in the assignments. maps that display historical census data help students place the subject ethnic group into the larger county, state, and national context over the time frame. the students can see, for instance, if their subject household was part of an ethnic cluster or an outlier to ethnic clusters. the parameters for finding data and maps are generous and open to each student’s interpretation. the wish is for students to find social statistics and maps that are insightful to their topic and will help them tell their story. of the three statistical resources considered above, currently the only useful one is social explorer because it covers the time period studied by the class. the students may map several social indicators at the county level across several decades and compare their local area to the region and the nation. also they may save their maps and include them in their papers (properly credited). case study 3 “the ghetto” is an elective geography class restricted to upperclassman at michigan state university. in the semester project, students analyze the spatial organization and demographic variables of “ghetto” neighborhoods in a chosen city. a ghetto is defined as neighborhoods that have a 50 percent or higher concentration of a definable ethnic group. since black and white are the only two races consistently reported at the census tract level for all the years covered by the class (1960 through 2010) the students necessarily use that data for their projects. data needs for the class are focused and deep. the students specifically need to visualize us census data from 1960 through 2010 at the census tract level within the city limits for several social indicators. indicators include median income, median housing value, median rent, educational attainment, income, and rate of unemployment. the instructor has traditionally required use of the paper census volumes and students created hand-made maps that highlight information technology and libraries | march 2013 31 tracts in the subject city that conformed to the ghetto definition and those that did not for each of the census years covered. computer-retrieved data and computer-generated maps would be acceptable, but at the time of this writing no gis lite product is able to make all the maps that meet the specific requirements of this class. social explorer covers all of the date range and provides data down to the tract level. however it does not provide an outline of the city limits and does not provide all the data variables required in the assignment. simplymap will only work for 2000 through 2010 because tract boundaries are only available for those two years even though the data go back to 1980. simplymap does provide two excellent features though: it is the only product that allows an overlay of the (modern) city boundary on top of the census tract map, ands it is the only product that allows manipulation of the data intervals. students may choose to break the data at the needed 50 percent mark, while the other products utilize fixed data intervals not useful to this class. proquest statistical datasets can compute the data into two categories to create the necessary data intervals; however census data are only available beginning with census 2000. map products for user needs these three real-life class scenarios illustrate how the rich and seemingly duplicative resources of the library can range from perfectly suitable to perfectly useless depending on each project’s exact needs. the appropriateness of any given tool can only be assessed fairly if the librarian is familiar with all the “ins and outs” of every product. the geoweb and gis lite tools mentioned throughout this article are summarized in table 1. the suitability of gis lite tools will be further affected by the following issues. historical boundaries the range and granularity of data tools are subject to factors sometimes at odds with what a researcher would wish to have. at this time, for instance, many historical resources provide data only as detailed as the county level. county level data are available largely due to the efforts of the nhgis mentioned above and the newberry library’s atlas of county boundaries project (http://publications.newberry.ort/ahcbp). far fewer resources provide historical data at smaller geographies such as city, township, or census tract levels. this is because the smaller the geographies get, the exponentially more there are to create and for map interfaces to process. from the well-known resource city and county data book,11 it is easy enough to retrieve us city data. the historical boundaries of every city in the united states, however, have not been created. this is because city boundaries are much more dynamic than county boundaries and there is no centralized authoritative source for their changes over time. two of the three case studies presented here utilized historic data. this isn’t necessarily a representative proportion of user needs; librarians should assess data resources in light of their own patrons’ needs. normalization two equally valid data needs concerning any kind of time series data concern changing geographic boundaries. census tracts, for instance, provide geographic detail roughly at the neighborhood level designed by the bureau of census to encompass approximately 2,500 to 8,000 http://publications.newberry.ort/ahcbp mapping for the masses: gis lite & online mapping tools in academic libraries | weessies and dotson 32 people.12 because people move around and the density of population changes from decade to decade, so the configuration and numbering of tracts change over time. some scholars will wish to see the data values in the tracts as they were drawn at the time of issue. in this situation, a neighborhood of interest might belong to different tracts over the years or even be split between two or more tracts. other scholars focused on a particular neighborhood may wish to see many decades of census data re-cast into stable tracts in order to be directly comparable. data providers will take one approach or the other on this issue, and librarians will do well to be aware of their choice. license restrictions a third issue affecting use of these products is the ability to use derived map images, not only in formal outlets such as professional presentations, articles, books, and dissertations, but also informal outlets such as blogs and tweets. for the most part gis lite vendors are willing—even pleased—to see their products promoted in the literature and in social media. the vendors uniformly wish any such use to be properly credited. the license that every institution signs when acquiring these products will specify allowed and disallowed activities. the license, fixated on disallowing abuse or resale or other commercialization of the data, might leave a chilling effect on users wishing to use the images in their work. if a user is in any doubt as to the suitability of an intended use of a map, he or she should be encouraged to contact the vendor to seek permission for its use. as data resources grow and become more readily usable, the possibility for scholarly inquiry grows. librarians with familiarity with gis lite tools may partner with their patrons and guide them to the best resources. information technology

214 information technology and libraries | december 2010 margaret brown-sica, jeffrey beall, and nina mchale next-generation library catalogs and the problem of slow response time and librarians will benefit from knowing what typical and acceptable response times are in online catalogs, and this information will assist in the design and evaluation of library discovery systems. this study also looks at benchmarks in response time and defines what is unacceptable and why. when advanced features and content in library catalogs increase response time to the extent that users become disaffected and use the catalog less, nextgen catalogs represent a step backward, not forward. in august 2009, the auraria library launched an instance of the worldcat local product from oclc, dubbed worldcat@auraria. the library’s traditional catalog—named skyline and running on the innovative interfaces platform—still runs concurrently with worldcat@auraria. because worldcat local currently lacks a library circulation module that the library was able to use, the legacy catalog is still required for its circulation functionality. in addition, skyline contains marc records from the serialssolution 360 marc product. since many of these records are not yet available in the oclc worldcat database, these records are being maintained in the legacy catalog to enable access to the library’s extensive collection of online journals. almost immediately upon implementation of worldcat local, many library staff began to express concern about the product’s slow response time. they bemoaned its slowness both at the reference desk and during library instruction sessions. few of the discussions of the product’s slow response time evaluated this weakness in the context of its advanced features. several of the reference and instruction librarians even stated that they refused to use it any longer and that they were not recommending it to students and faculty. indeed, many stated that they would only use the legacy skyline catalog from then on. therefore we decided to analyze the product’s response time in relation to the legacy catalog. we also decided to further our study by examining response time in library catalogs in general, including several different online catalog products from different vendors. ■■ response time the term response time can mean different things in different contexts. here we use it to mean the time it takes for all files that constitute a single webpage (in the case of testing performed, a permalink to a bibliographic record) to travel across the internet from a web server to the computer on which the page is to be displayed. we do not include the time it takes for the browser to render the page, only the time it takes for the files to arrive to the requesting computer. typically, a single webpage is made of multiple files; these are sent via the internet from a web response time as defined for this study is the time that it takes for all files that constitute a single webpage to travel across the internet from a web server to the end user’s browser. in this study, the authors tested response times on queries for identical items in five different library catalogs, one of them a next-generation (nextgen) catalog. the authors also discuss acceptable response time and how it may affect the discovery process. they suggest that librarians and vendors should develop standards for acceptable response time and use it in the product selection and development processes. n ext-generation, or nextgen, library catalogs offer advanced features and functionality that facilitate library research and enable web 2.0 features such as tagging and the ability for end users to create lists and add book reviews. in addition, individual catalog records now typically contain much more data than they did in earlier generations of online catalogs. this additional data can include the previously mentioned tags, lists, and reviews, but a bibliographic record may also contain cover images, multiple icons and graphics, tables of contents, holdings data, links to similar items, and much more. this additional data is designed to assist catalog users in the selection, evaluation, and access of library materials. however, all of the additional data and features have the disadvantage of increasing the time it takes for the information to flow across the internet and reach the end user. moreover, the code that handles all this data is much more complex than the coding used in earlier, traditional library catalogs. slow response time has the potential to discourage both library patrons from using the catalog and library staff from using or recommending it. during a reference interview or library instruction session, a slow response time creates an awkward lull in the process, a delay that decreases confidence in the mind of library users, especially novices who are accustomed to the speed of an open internet search. the two-fold purpose of this study is to define the concept of response time as it relates to both traditional and nextgen library catalogs and to measure some typical response times in a selection of library catalogs. libraries margaret brown-sica (margaret.brown-sica@ucdenver.edu) is assistant professor, associate director of technology strategy and learning spaces, jeffrey beall (jeffrey.beall@ucdenver.edu) is assistant professor, metadata librarian, and nina mchale (nina.mchale@ucdenver.edu) is assistant professor, web librarian, university of colorado denver. next-generation library catalogs | brown-sica, beall, and mchale 215 mathews posted an article called “5 next gen library catalogs and 5 students: their initial impressions.”7 here he shares student impressions of several nextgen catalogs. regarding slow response time mathews notes, “lots of comments on slowness. one student said it took more than ten seconds to provide results. some other comments were: ‘that’s unacceptable’ and ‘slow-motion search, typical library.’” nagy and garrison, on lauren’s library blog, emphasized that any “cross-silo federated search” is “as slow as the slower silos.”8 any search interface is as slow as the slowest database from which it pulls information; however, that does not make users more likely to wait for search results. in fact, many users will not even know—or care—what is happening behind the scenes in a nextgen catalog. the assertion that slow response time makes wellintentioned improvements to an interface irrelevant is supported by an article that analyzes the development of semantic web browsers. frachtenberg notes that users, however, have grown to expect web search engines to provide near-instantaneous results, and a slow search engine could be deemed unusable even if it provides highly relevant results. it is therefore imperative for any search engine to meet its users’ interactivity expectations, or risk losing them.9 this is not just a library issue. users expect a fast response to all web queries, and we can learn from studies on general web response time and how it affects the user experience. huang and fong-ling help explain different user standards when using websites. their research suggests that “hygiene factors” such as “navigation, information display, ease of learning and response time” are more important to people using “utilitarian” sites to accomplish tasks rather than “hedonistic” sites.10 in other words, response time importance increases when the user is trying to perform a task— such as research—and possibly even more for a task that may be time sensitive—such as trying to complete an assignment for class. ■■ method for testing response time in an assortment of library catalogs, we used the websitepulse service (http://www .websitepulse.com). websitepulse provides in-depth website and server diagnostic services that are intended to save e-business customers time and money by reporting errors and web server and website performance issues to clients. a thirty-day free trial is available for potential customers to review the full array of their services; however, the free web page test, available at http://www.website server and arrive sequentially at the computer where the request was initiated. while the world wide web consortium (w3c) does not set forth any particular guidelines regarding response time, go-to usability expert jakob nielsen states that “0.1 second is about the limit for having the user feel that the system is reacting instantaneously.”1 he further posits that 1.0 second is “about the limit for the user’s flow of thought to stay uninterrupted, even though the user will notice the delay.”2 finally, he asserts that: 10 seconds is about the limit for keeping the user’s attention focused on the dialogue. for longer delays, users will want to perform other tasks while waiting for the computer to finish, so they should be given feedback indicating when the computer expects to be done. feedback during the delay is especially important if the response time is likely to be highly variable, since users will then not know what to expect.3 even though this advice dates to 1994, nielsen noted even then that it had “been about the same for many years.”4 ■■ previous studies the chief benefit of studying response time is to establish it as a criterion for evaluating online products that libraries license and purchase, including nextgen online catalogs. establishing response-time benchmarks will aid in the evaluation of these products and will help libraries convey the message to product vendors that fast response time is a valuable product feature. long response times will indicate that a product is deficient and suffers from poor usability. it is important to note, however, that sometimes library technology environments can be at fault in lengthening response time as well; in “playing tag in the dark: diagnosing slowness in library response time,” brown-sica diagnosed delays in response time by testing such variables as vendor and proxy issues, hardware, bandwidth, and network traffic.5 in that case, inadequate server specifications and settings were at fault. while there are many articles on nextgen catalogs, few of them discuss the issue of response time in relation to their success. search slowness has been reported in library literature about nextgen catalogs’ metasearch cousins, federated search products. in a 2006 review of federated search tools metalib and webfeat, chen noted that “a federated search could be dozens of times slower than google.”6 more comments about the negative effects of slow response time in nextgen catalogs can be found in popular library technology blogs. on his blog, 216 information technology and libraries | december 2010 ■■ findings: skyline versus worldcat@auraria in figure 2, the bar graph shows a sample load time for the permalink to the bibliographic record for the title hard lessons: the iraq reconstruction experience in skyline, auraria’s traditional catalog load time for the page is pulse.com/corporate/alltools.php, met our needs. to use the webpage test, simply select “web page test” from the dropdown menu, input a url—in the case of the testing done for this study, the permalink for one of three books (see, for example, figure 1)—enter the validation code, and click “test it.” websitepulse returns a bar graph (figure 2) and a table (figure 3) of the file activity from the server sending the composite files to the end user ’s web browser. each line represents one of the files that make up the rendered webpage. they load sequentially, and the bar graph shows both the time it took for each file to load and the order in which the files were received. longer segments of the bar graph provide visual indication of where a slow-loading webpage might encounter sticking points—for example, waiting for a large image file or third-party content to load. accompanying the bar graph is a table describing the file transmissions in more detail, including dns, connection, file redirects (if applicable), first and last bytes, file transmission times, and file sizes. figure 1. permalink screen shot for the record for the title hard lessons in auraria library’s skyline catalog figure 2. websitepulse webpage test bar graph

mchale 217 requested at items 8, 14, 15, 17, 26, and 27. the third parties include yahoo! api services, the google api service, recaptcha, and addthis. recaptcha is used to provide security within worldcat local with optical character recognition images (“captchas”), and the addthis api is used to provide bookmarking functionality. at number 22, a connection is made to the auraria library web server to retrieve a logo image hosted on the web server. at number 28, the cover photo for hard lessons is retrieved from an oclc server. the files listed in figure 6 details the complex process of web browsers’ assembly of them. each connection to third-party content, while all relatively short, allows for additional features and functionality, but lengthens overall response. as figure 6 shows, the response time is slightly more than 10 seconds, which, according to nielsen, “is about the limit for keeping the user ’s attention focused on the dialogue.”12 while widgets, third-party content, and other web 2.0 tools add desirable content and functionality to the library’s catalog, they also do slow response time considerably. the total file size for the bibliographic record in worldcat@auraria—compared to skyline’s 84.64 kb—is 633.09 kb. as will be shown in the test results below for the catalog and nextgen catalog products, bells and whistles added to traditional 1.1429 seconds total. the record is composed of a total of fourteen items, including image files (gifs), cascading style sheet (css) files, and javascript (js) files. as the graph is read downward, the longer segments of the bars reveal the sticking points. in the case of skyline, the nine image files, two css files, and one js file loaded quickly; the only cause for concern is the red line at item four. this revealed that we were not taking advantage of the option to add a favicon to our iii catalog. the web librarian provided the ils server technician with the same favicon image used for the library’s website, correcting this issue. the skyline catalog, judging by this data, falls into nielsen’s second range of user expectations regarding response time, which is more than one second, or “about the limit for the user’s flow of thought to stay uninterrupted, even though the user will notice the delay.”11 further detail is provided in figure 3; this table lists each of the webpage’s component files, and various times associated with the delivery of each file. the column on the right lists the size in kilobytes of each file. the total size of the combined files is 84.64 kb. in contrast to skyline’s meager 14 files, worldcat local requires 31 items to assemble the webpage (figure 4) for the same bibliographic record. figures 5 and 6 show that this includes 10 css files, 10 javascript files, and 8 images files (gifs and pngs). no item in particular slows down the overall process very much; the longestloading item is number 13, which is a wait for third-party content, a connection to yahoo!’s user interface (yui) api service. additional third-party content is being figure4. permalink screen shot for the record for the title hard lessons in worldcat@auraria figure 5.

reported by the websitepulse tests; this number appears near the lower right-hand corner of the tables in figures 3, 6, 9, 12, and 15. we selected three books that were each held by all five of our test sites, verifying that we were searching the same three bibliographic records in each of the online catalogs by looking at the oclc number in the records. each of the catalogs we tested has a permalink feature; this is a stable url that always points to the same record in each catalog. using a permalink approximates conducting a known-item search for that item from a catalog search screen. we saved these links and used them in our searches. the bibliographic records we tested were for these books; the permalinks used for testing follow the books: book 1: hard lessons: the iraq

collection, we also tested three other non-auraria catalogs. we designed our study to incorporate a number of variables. we decided to link to bibliographic records for three different books in the five different online catalogs tested. these included skyline and worldcat@auraria as well three additional online public access catalog products, for a total of two instances of innovative interfaces products, one of a voyager catalog, and one of a sirsidynix catalog. we also selected online catalogs in different parts of the country: worldcatlocal in ohio; skyline in denver; the library of congress’ online catalog (lcoc) in washington, d.c.; the university of texas at austin’s (ut austin) online catalog; and the university of southern california’s (usc) online catalog, named homer, in los angeles. we also did our testing at different times of the day. one book was tested in the morning, one at midday, and one in the afternoon. websitepulse performs its webpage tests from three

university of colorado denver: skyline (innovative interfaces) as previously mentioned, the traditional catalog at auraria library runs on an innovative interfaces integrated library system (ils). testing revealed a missing favicon image file that the web server tries to send each time (item 4 in figure 3). however, this did not negatively affect the response time. the catalog’s response time was good, with an average of 1.2930 seconds, giving it the fastest average time among all the test sites in the testing period. as figure 1 shows, however, skyline is a typical legacy catalog that is designed for a traditional library environment. library of congress: online catalog (voyager) the average response time for the lcoc was 2.0076 ■■ results the data shows the response times for each of the three books in each of the five online catalogs over the thirteenday testing period. the raw data was used to calculate averages for each book in each of the five online catalogs, and then we calculated averages for each of the five online catalogs (table 4). the averages show that during the testing period, the response time varied between 1.2930 seconds for the skyline library catalog in denver to 11.5734 seconds for worldcat@auraria, which has its servers in ohio. university of colorado denver: worldcat@auraria worldcat@auraria was routinely over nielsen’s ten second limit, sometimes taking as long as twenty seconds to load all the files to generate a single webpage. as previously discussed, this is due to the high number and variety of files that make up a single bibliographic record. the files sent also include cover images, but they are small and do not add much to the total time. after our tests on worldcat@auraria were conducted, the site removed one of the features on pages for individual resources, namely the “similar items” feature. this feature was one of the most file-intensive on a typical page, and its removal should speed up page loads. however, worldcat@auraria had the highest average response time by far of the five catalogs tested. figure 7. permalink screen shot for the record for the title hard lessons in the library of congress online

record next-generation library catalogs | brown-sica, beall, and mchale 221 item 14 is a script, that while hosted on the ils server, queries amazon.com to return cover image art (figures 11–12). the average response time for ut austin’s catalog was 3.4997 seconds. this example demonstrates that response times for traditional (i.e., not nextgen) catalogs can be slowed down by additional content as well. university of southern california: homer (sirsidynix) the average response time for usc’s homer catalog was 4.1085 seconds, making it the second slowest after seconds. this was the second fastest average among the five catalogs tested. while, like skyline, the bibliographic record page is sparsely decorated (figure 7), this pays dividends in response time, as there are only two css files and three gif files to load after the html content loads (figure 9). figure 8 shows that initial connection time is the longest factor in load time; however, it is still short enough to not have a negative effect. total file size is 19.27 kb. as with skyline, the page itself (figure 7) is not particularly end-user friendly to nonlibrarians. university of texas at austin: library catalog (innovative interfaces) ut austin, like auraria library, runs an innovative interfaces ils. the library catalog also includes book cover images, one of the most attractive nextgen features (figure 10), and as shown in figure 12, third-party content is used to add features and functionality (items 16 and 17). ut austin’s catalog uses a google javascript api (item 16 in figure 12) and librarything’s catalog enhancement product, which can add book recommendations, tag browsing, and alternate editions and translations. total content size for the bibliographic record is considerably larger than skyline and the lcoc at 138.84 kb. it appears as though inclusion of cover art nearly doubles the response time; figure 10. permalink screen shot for the record for the title hard lessons

test table results for university of texas at austin’s library catalog record 222 information technology and libraries | december 2010 completed. added functionality and features in library search tools are valuable, but there is a tipping point when these features slow down a product’s response time to where users find the search tool too slow or unreliable. based on the findings of this study, we recommend that libraries adopt web response time standards, such as those set forth by nielsen, for evaluating vendor search products and creating in-house search products. commercial tools like websitepulse make this type of data collection simple and easy. testing should be conducted for an extended period of time, preferably during a peak period—i.e., during a busy time of the semester for academic libraries. we further recommend that reviews of electronic resources add response time as an worldcat@auraria, and the slowest among the traditional catalogs. this sirsidynix catalog appears to take a longer time than the other brands of catalogs to make the initial connection to the ils; this accounts for much of the slowness (see figures 14 and 15). once the initial connection is made, however, the remaining content loads very quickly, with one exception: item 13 (see figure 15), which is a connection to the third-party provider syndetic solutions, which provides cover art, a summary, an author biography, and a table of contents. while the display of this content is attractive and well-integrated to the catalog (figure 13), it adds 1.2 seconds to the total response time. also, as shown in item 14 and 15, usc’s homer uses the addthis service to add bookmarking enhancements to the catalog. total combined file size is 148.47 kb, with the bulk of the file size (80 kb) coming from the initial connection (item 1 in figure 15). ■■ conclusion an eye-catching interface and valuable content are lost on the end user if he or she moves on before a search is

 mobile  services  among  academic  libraries  of  the  country’s  top  100   universities,  and  what  are  the  best  practices  for  librarians  implementing  mobile  services  at  the   university  level?  through  in-­‐depth  website  visits  and  survey  questionnaires,  the  authors  studied  each   of  the  top  100  universities’  libraries’  experiences  with  mobile  services.  results  showed  that  all  of  these   libraries  offered  at  least  one  mobile  service,  and  the  majority  offered  multiple  services.  the  most   common  mobile  services  offered  were  mobile  sites,  text  messaging  services,  e-­‐books,  and  mobile   access  to  databases  and  the  catalog.  in  addition,  chat/im  services,  social  media  accounts  and  apps   were  very  popular.    survey  responses  also  indicated  a  trend  towards  responsive  design  for  websites  so   that  patrons  can  access  the  library’s  full  site  on  any  mobile  device.  respondents  recommend  that   libraries  considering  offering  mobile  services  begin  as  soon  as  possible  as  patron  demand  for  these   services  is  expected  to  increase.   introduction    mobile  devices,  such  as  smart  phones,  tablets,  e-­‐book  readers,  handheld  gaming  tools  and   portable  music  players  are  practically  omnipresent  in  today’s  society.  according  to  walsh  (2012),   “mobile  data  traffic  in  2011  was  eight  times  the  size  of  the  global  internet  in  2000  and,  according   to  forecasts,  mobile  devices  will  soon  outnumber  human  beings”.1  studies  have  revealed  that  use   of  mobile  devices  is  widespread  and  continues  to  increase.  as  of  2013,  56%  of  americans  owned  a   smart  phone  (smith  2013).  this  number  is  even  higher  among  people  ages  18  to  29.2  however,   peters  (2011)  points  out  that  mobile  phones  at  least  can  be  found  among  people  of  all  ages,   nationalities  and  socioeconomic  classes.  he  writes,  “we  truly  are  in  the  midst  of  a  global  mobile   revolution.”3  in  2012,  the  acrl  research  planning  and  review  committee  found  that  55%  of   undergraduates  have  smart  phones,  62%  have  ipods,  and  21%  have  some  kind  of  tablet.  over  67%   of  these  students  use  their  devices  academically.4  elmore  and  stephens  (2012)  write,  “academic   libraries  cannot  afford  to  ignore  this  growing  trend.  for  many  students  a  mobile  phone  is  no   longer  just  a  telephonic  device  but  a  handheld  information  retrieval  tool.”5       yan  quan  liu  (liuy1@southernct.edu)  is  professor  in  information  and  library  science  at   southern  connecticut  state  university,  new  haven,  ct,  and  special  hired  professor  at  tianjin   university  of  technology,  tianjin,  china.  sarah  briggs  (sjg.librarian@gmail.com)  is   library/media  specialist  at  jonathan  law  high  school,  milford,  ct.     a  library  in  the  palm  of  your  hand:  mobile  services  in  the  top  100  university  libraries  |     liu  and  briggs  |  doi:  10.6017/ital.v34i2.5650   134   it  is  clear  from  these  studies  that  academic  libraries  can  expect  their  patrons  to  be  accessing  their   services  via  mobile  devices  in  growing  numbers  and  need  to  adapt  to  this  reality.  however,  the   sheer  number  of  mobile  devices  on  the  market  and  the  myriad  ways  libraries  could  offer  mobile   services  can  be  daunting.  additionally,  offering  mobile  services  requires  investing  time,  money,   and  personnel.  in  order  to  give  libraries  a  starting  point,  this  paper  examines  the  current  status  of   mobile  services  in  the  united  states’  top  100  universities’  libraries  as  a  model,  specifically  what   services  are  being  offered,  what  are  they  being  used  for,  and  what  challenges  libraries  have   encountered  in  offering  mobile  services.  in  doing  so,  this  paper  attempts  to  answer  two  questions:   what  is  the  state  of  mobile  services  among  academic  libraries  of  the  country’s  top  ranked   universities,  and  what  can  the  experiences  of  these  libraries  teach  us  about  best  practices  for   mobile  services  at  the  university  level?     literature  review   current  status  of  mobile  services  in  academic  libraries   there  is  not  a  lot  of  data  regarding  the  prevalence  of  mobile  services  in  academic  libraries.  a  2010   study  found  that  35%  of  the  english  speaking  members  of  the  association  of  research  libraries   had  a  mobile  website  for  either  the  university,  the  library,  or  both  (canuel  and  crichton  2010).6  a   study  of  chinese  academic  libraries  revealed  that  only  12.8%  surveyed  had  a  section  of  their  web   pages  devoted  to  mobile  library  service  (li  2013).7  in  2010,  canuel  and  crichton  found  that  13.7%   of  association  of  universities  and  colleges  of  canada  members  had  some  mobile  services,   including  websites  and  apps.8  in  the  united  states,  a  2010  survey  found  that  44%  of  academic   libraries  offered  some  type  of  mobile  service.  39%  had  a  mobile  website,  and  36%  had  a  mobile   version  of  the  library’s  catalog.  half  of  libraries  which  did  not  offer  mobile  services  were  in  the   planning  process  for  creating  a  mobile  website,  catalog,  and  text  notifications.  additionally,  40%   planned  on  implementing  sms  reference  services,  and  54%  wanted  the  ability  to  access  library   databases  on  mobile  devices  (thomas  2010).9  however,  it  is  widely  assumed  that  mobile  services   will  expand  rapidly  in  the  future  (canuel  and  crichton  2010).10  more  recently,  a  2012  survey  of   academic  libraries  in  the  pacific  northwest  found  that  50%  had  a  mobile  version  of  the  library’s   website  and/or  catalog,  40%  used  qr  codes,  38%  had  a  text  messaging  service,  and  18%  replied   “other”  with  mobile  interfaces  for  databases  being  a  popular  offering.  however,  31%  of  survey   respondents  still  did  not  have  any  mobile  services  (ashford  and  zeigen  2012).11  osika  and   kaufman  (2012)  surveyed  community  and  junior  colleges  nationwide  to  determine  what  mobile   services  were  being  offered.  73%  offered  mobile  catalog  access,  62%  offered  vendor  database   apps,  two  were  creating  a  mobile  app  for  the  library,  and  14.7%  had  a  mobile  library  website.12         definition  and  types  of  mobile  services   although  there  are  dozens  of  different  mobile  devices  on  the  market,  la  counte  (2013)  aptly  and   succinctly  defines  them  as  follows:  “the  reality  is  that  mobile  devices  can  refer  to  essentially  any   device  that  someone  uses  on  the  go”  (vi).13  smart  phones,  netbooks,  tablet  computers,  e-­‐readers,     information  technologies  and  libraries  |  june  2015   135   gaming  devices  and  ipods  are  examples  of  mobile  devices  that  are  now  commonplace  on  college   campuses.  barnhart  and  pierce  (2012)  define  these  devices  as  “…networked,  portable,  and   handheld…”14  additionally,  these  devices  may  be  used  to  read,  listen  to  music,  and  watch  videos   (west,  hafner  and  faust  2006).15  according  to  lippincott  (2008),  libraries  should  consider  all   their  patron  groups  as  potential  mobile  library  users,  including  faculty,  distance  education   students,  on-­‐campus  students,  students  placed  in  internships  or  doing  other  kinds  of  fieldwork,   and  students  using  mobile  devices  to  work  on  collaborative  projects  outside  of  school.16     the  most  common  mobile  services  discussed  in  the  literature  are  mobile-­‐friendly  websites  or  apps,   mobile-­‐friendly  access  to  the  library’s  catalog  and  databases,  text  messaging  services,  qr  codes,   augmented  reality,  e-­‐books,  and  information  literacy  instruction  facilitated  by  mobile  devices.   these  services  fall  into  one  of  two  categories:  traditional  library  services  amended  to  be  available   with  mobile  devices  and  services  created  specifically  for  mobile  devices.     common  library  services  that  have  been  updated  to  be  mobile-­‐friendly  include  a  mobile  website   (either  as  a  mobile  version  of  the  library’s  regular  site,  an  app,  or  both),  mobile-­‐friendly  interfaces   for  the  library’s  catalog  and  databases,  access  to  books  in  electronic  format,  and  information   literacy  instruction  which  makes  use  of  mobile  devices.  regarding  mobile  websites  and  apps,   walsh  (2012)  writes,     “if  a  well-­‐designed  app  is  like  a  top-­‐end  sports  car,  a  mobile  website  is  more  like  a  family  run-­‐ around.  it  may  not  be  as  good  looking,  but  it  is  likely  to  be  cheaper,  easier  to  run  and   accessible  to  more  people.”17     it  is  not  feasible  to  replicate  the  entire  website  in  a  mobile  version,  so  libraries  must  know  what   patrons  find  most  important  and  address  that  information  through  the  mobile  site  (walsh  2012).18   according  to  a  2012  survey  of  academic  libraries  in  the  pacific  northwest,  the  most  popular  types   of  information  found  on  mobile  websites  are  links  to  the  catalog,  a  way  to  contact  a  librarian,  links   to  databases,  and  hours  of  operation  (ashford  and  zeigen  2012).19  many  libraries  are  also   providing  mobile  access  to  their  catalogs  and  databases.  this  is  sometimes  difficult  because  often   third-­‐party  vendors  are  responsible  for  the  catalogs  and/or  databases,  and  libraries  must  rely  on   these  vendors  to  provide  mobile  access  (iglesias  and  meesangnil  2011).20  however,  many  vendors   already  offer  mobile-­‐friendly  interfaces;  libraries  must  be  aware  when  this  is  the  case  and  provide   links  to  these  interfaces.  when  a  vendor  does  not  provide  a  mobile-­‐friendly  interface,  the  library   should  encourage  the  vendor  to  do  so  (bishoff  2013,  p.  118).21     there  is  a  growing  expectation  that  libraries  will  provide  e-­‐books  to  patrons  as  e-­‐books  become   increasingly  popular.  walsh  (2012)  states  that  the  proportion  of  adults  in  the  united  states  who   own  an  e-­‐book  reader  doubled  between  november  2010  and  may  2011.22  according  to  bischoff,   ruth,  and  rawlins  (2013),  29%  of  americans  owned  a  tablet  or  e-­‐reader  as  of  january  2012.23  this   has  presented  challenges  for  libraries,  mainly  in  two  areas:  format  and  licensing.  there  is  risk   involved  in  choosing  a  format  that  will  only  work  with  one  product,  i.e.  a  nook  or  a  kindle,     a  library  in  the  palm  of  your  hand:  mobile  services  in  the  top  100  university  libraries  |     liu  and  briggs  |  doi:  10.6017/ital.v34i2.5650   136   because  not  every  patron  will  own  the  same  device,  and  ultimately  one  device  might  become  the   most  popular,  rendering  books  purchased  for  other  devices  obsolete.  on  the  other  hand,  formats   that  work  with  multiple  devices  tend  to  have  only  basic  functionality  and  do  not  provide  an  ideal   user  experience  (walsh  2012).24  walsh  (2012)  recommends  epub,  which  works  well  with  many   different  devices,  is  free,  and  supports  the  addition  of  a  digital  rights  management  layer.25   licensing  is  also  an  issue  as  libraries  and  publishers  strive  to  find  a  method  of  loaning  e-­‐books   amenable  to  both.  no  one  model  has  emerged  which  is  mutually  satisfactory  (walsh  2012).26             libraries  are  increasingly  integrating  mobile  technologies  into  information  literacy  instruction   and  other  forms  of  instruction.  for  example,  services  such  as  skype  and  facetime,  which  walsh   (2012)  describes  as  “a  window  to  another  world”  (p.  105),  can  be  used  for  distance  learning,   including  reference  and  instruction.27  when  interactions  do  not  need  to  take  place  live,  many   mobile  devices  have  the  capability  to  take  pictures,  record  video,  and  record  audio  (walsh  2012,  p.   97).28  this  allows  class  events,  including  lectures  and  discussions,  to  be  broadcast  to  people  and   spaces  beyond  the  physical  classroom.  walsh  (2012)  notes  that,  when  constructing  podcasts  or   vodcasts,  it  is  important  to  make  mobile-­‐friendly  versions  of  these  available,  bearing  in  mind   different  platforms  and  screen  sizes  people  might  be  using  to  access  the  content.29      text  messaging,  qr  codes,  and  augmented  reality  are  examples  of  library  services  that  were   created  expressly  for  mobile  devices.  text  messaging  in  particular  has  become  a  very  popular   mobile  service  offering;  as  thomas  and  murphy  (2009)  write,  “interacting  with  patrons  through   text  messaging  now  ranks  among  core  competencies  for  librarians  because  sms  increasingly   comprises  a  central  channel  for  communicating  library  information.”30  a  common  use  of  text   messaging  is  a  ‘text  a  librarian’  service.  walsh  (2012)  recommends  launching  such  a  service  even   if  the  library  currently  offers  no  other  mobile  services,  noting,  “it  can  be  quick,  easy  and  cheap  to   introduce  such  a  service  and  it  is  an  ideal  entry  into  the  world  of  providing  services  via  mobile   devices”  (p.  45).31  peters  (2011)  points  out  that  the  shorter  the  turnaround  time  (he  recommends   less  than  ten  minutes)  the  better.  he  notes  that  many  questions  arise  as  the  result  of  a  situation   the  questioner  is  currently  in.  he  writes,  “if  you  do  not  respond  in  a  matter  of  minutes,  not  hours,   the  context  will  be  lost  and  the  need  will  be  diminished  or  satisfied  in  other  ways.”32   qr  codes  have  become  popular  in  libraries  offering  mobile  services.  qr  codes  encode  information   in  two  dimensions  (vertically  and  horizontally),  and  thus  can  provide  more  information  than  a   barcode.  the  applications  necessary  for  using  qr  codes  are  usually  free,  and  they  can  be  read  by   most  mobile  devices  with  cameras  (little  2011).33  the  most  common  uses  of  qr  codes  in   academic  libraries,  according  to  elmore  and  stephens  (2012),  are  linking  to  the  library’s  mobile   website  and  social  media  pages,  searching  the  library  catalog,  viewing  a  video  or  accessing  a  music   file,  reserving  a  study  room,  and  taking  a  virtual  tour  of  the  library  facilities.34     augmented  reality  may  not  currently  be  used  as  often  in  libraries  as  other  services  such  as  mobile   sites  and  text  messaging,  but  many  libraries  are  finding  unique  and  compelling  ways  to  use  ar.  ar   applications  link  the  physical  with  the  digital,  are  interactive  in  real  time,  and  are  registered  in  3-­‐d.     information  technologies  and  libraries  |  june  2015   137   hahn  (2012)  defines  ar  as  follows:  “in  order  to  be  considered  a  truly  augmented  reality   application,  an  app  must  interactively  attach  graphics  or  data  to  objects  in  real  time,  to  achieve  the   real  and  virtual  combination  of  graphics  into  the  physical  environment.”35  he  notes  that  such   applications  are  excellent  additions  to  libraries’  mobile  services  because  they  connect  physical  and   digital  worlds,  much  like  libraries.36  one  example  of  augmented  reality  is  north  carolina  state   university’s  wolfwalk,  which  is  advertised  as  “…a  historical  walking  tour  of  the  nc  state  campus   using  the  location-­‐aware  campus  map”  (ncsu  libraries).37  to  create  the  tour,  the  ncsu  libraries   special  collections  research  center  provided  over  one  thousand  photographs  of  the  campus  from   the  19th  century  to  the  present  (ncsu  libraries).38     research  design   to  make  sure  the  information  gathered  was  current  and  valid,  this  study  employed  two   approaches,  website  visits  and  survey  investigation,  to  determine  the  state  of  mobile  services  at   the  top  100  universities’  libraries.  the  website  visits  explored  what  mobile  services  are  being   offered  and  how  they  are  being  offered  at  these  university  libraries.  the  survey  sent  via  email   inquired  how  they  are  providing  mobile  services  in  their  libraries  and  what  their  results  have   been  regarding  challenges,  successes,  and  best  practices.  the  survey  data  was  analyzed  and   compared  to  the  data  obtained  via  website  exploration  to  form  a  more  comprehensive  picture  of   mobile  services  at  these  universities.   participants   university  libraries'  patrons  are  frequent  users  of  mobile  technology.  according  to  osika  and   kaufman  (2012),  studies  have  found  that  45%  of  18  to  29-­‐year-­‐olds  who  have  internet-­‐capable   cell  phones  do  most  of  their  browsing  on  their  devices.  39  kostruski  and  skornia  (2011)  note  that   people  of  this  age  group  are  “…leaders  in  mobile  communication…the  traditional  college-­‐age   student.”40  as  the  nation’s  leaders  in  undergraduate  and  graduate  programs  and  academic   research,  an  examination  of  the  status  of  the  top  100  university  libraries'  mobile  services  can   provide  useful  service  patterns  and  a  benchmark  for  the  service  improvements  that  would  benefit   academic  programs.  based  on  the  u.s.  news  &  world  report's  national  university  rankings,  this   study  selected  the  top  100  universities  in  the  2014  rankings.41     procedure   website  visits  as  the  first  step  were  conducted  from  march  2,  2014  to  march  16,  2014.  each   library’s  home  page  was  carefully  examined  for  the  most  common  mobile  services  named  in  the   literature  with  these  categorized  items:  1)  a  mobile  website  or  app,  2)  mobile  access  to  the   library’s  catalog  and  databases,  3)  text  messaging  services,  4)  qr  codes,  5)  augmented  reality,  and   6)  e-­‐books.  to  assess  each  site,  we  first  visited  the  site  via  a  nexus  7  to  see  if  it  had  a  mobile   version.  next,  we  viewed  each  library’s  full  site  on  a  laptop  computer.  we  browsed  through  each   page  of  the  site  looking  for  mention  or  use  of  each  said  categorization.  we  also  searched  for  these     a  library  in  the  palm  of  your  hand:  mobile  services  in  the  top  100  university  libraries  |     liu  and  briggs  |  doi:  10.6017/ital.v34i2.5650   138   items  via  the  library’s  site  map  or  site  search  functions  whenever  available.  the  results  were   tabulated  with  a  codebook  in  the  established  categorization  through  microsoft  excel.     although  the  website  visits  place  great  value  on  gathering  quantitative  data  about  what  mobile   services  are  offered  at  these  libraries,  this  method  has  its  limitations.  firstly,  it  locates  only  those   mobile  services  that  appear  on  a  library’s  website,  but  services  the  library  provides  which  are  not   mentioned  on  the  website  can  be  overlooked.  also,  the  use  of  mobile  devices  or  services  in  library   instruction,  a  very  commonly  mentioned  mobile  service  in  the  literature,  cannot  generally  be   determined  via  a  website  visit.  in  addition,  the  website  visit  provides  only  a  snapshot  of  the   current  state  of  mobile  services;  university  libraries  may  be  planning  to  implement  or  even  be  in   the  process  of  implementing  mobile  services.  lastly,  website  visits  evaluate  what  is  publicly   available,  but  it  is  not  possible  to  access  password-­‐protected  information  meant  only  for  a   university’s  students  and  faculty  to  assess  mobile  content.  to  address  these  shortcomings,  we   created  a  survey  using  surveymonkey  to  complement  the  data  supplied  from  the  website  visits.   we  sent  out  the  survey  via  email  to  each  of  the  top  100  universities’  libraries.    the  survey  was   conducted  from  april  10,  2014,  to  april  24,  2014.     results  and  analysis   study  results  presented  compelling  evidence  that  mobile  services  are  already  ubiquitous  among   the  country's  top  universities.  the  most  recognized  ones  are  mobile  sites,  mobile  apps,  mobile   opacs,  mobile  access  to  databases,  text  messaging  services,  qr  codes,  augmented  reality,  and  e-­‐ books.  these  service  forms  confirm  those  commonly  named  in  the  literature  as  library  mobile   services.   what  basic  types  of  mobile  services  do  the  libraries  provide?   the  results  showed  all  of  the  libraries  offered  one  or  more  of  the  specific  mobile  services  in  chart   1  with  multiple  entries  allowed,  presenting  modernized  new  service  patterns  the  university   libraries  provide  to  meet  the  needs  and  demands  of  university  communities  in  this  digital  era.     information  technologies  and  libraries  |  june  2015   139     chart  1.  percentage  of  libraries  offering  specific  mobile  services  (multiple  entries  allowed).   it  is  clear  from  both  the  survey  results  and  the  website  visits  that  almost  all  libraries  at  the  top   100  universities  are  offering  multiple  mobile  services,  with  mobile  websites,  mobile  access  to  the   library’s  catalog,  mobile  access  to  the  library’s  databases,  e-­‐books,  and  text  messaging  services   being  the  most  common.  qr  codes  and  especially  augmented  reality  are  not  as  common.     of  the  eight  main  mobile  services  we  looked  for  via  the  website  visits  and  survey  (mobile  site,   mobile  app  for  the  site,  mobile  opac,  mobile  access  to  databases,  text  messaging,  qr  codes,   augmented  reality,  and  e-­‐books),  all  libraries  surveyed  offer  between  one  and  seven  of  these   services.  no  universities  have  none  of  these  services,  and  no  universities  have  all  of  these  services.   only  one  university  has  one  service,  none  have  two,  seven  have  three,  thirteen  have  four,  twenty-­‐ four  have  five,  forty-­‐six  have  six,  and  eight  have  seven.  to  make  this  information  easy  to  read,  we   summarized  it  in  table  1  below.   number

 university  libraries  |     liu  and  briggs  |  doi:  10.6017/ital.v34i2.5650   140   such  a  data  pattern  demonstrates  not  only  that  mobile  services  are  very  widespread  at  these   universities’  libraries,  but  also  that  the  vast  majority  of  these  libraries  offer  multiple  mobile   services.  in  other  words,  libraries  do  not  appear  to  be  offering  mobile  services  in  isolation;  they   have  taken  several  of  their  most  popular  services  (such  as  websites,  reference,  and  search   functions)  and  mobilized  all  of  them.  in  fact,  the  average  number  of  mobile  services  offered  among   the  eight  services  we  examined  is  5.31.      although  results  collected  from  the  two  research  methods  (website  visits  and  survey)  are  almost   identical  for  mobile  websites  and  mobile  opacs  and  are  very  comparable  for  text  messaging,  qr   codes,  and  augmented  reality  there  is  a  bit  of  a  gap  between  results  from  the  website  visits  and  the   survey  regarding  mobile  databases  (92.9%  vs.  70.59%),  but  perhaps  libraries  that  responded  to   the  survey  just  happened  to  offer  mobile  access  to  databases  less  often  than  all  the  libraries  in   general.      it  is  interesting  that  we  located  e-­‐books  on  100%  of  the  websites  we  visited,  but  only  85.29%  of   respondents  mention  offering  them.  perhaps  this  discrepancy  can  be  explained  by  a  clarification  in   terms.  we  looked  for  the  presence  of  books  in  electronic  format  that  could  be  accessed  online.   perhaps  survey  respondents  only  considered  e-­‐books  specifically  formatted  for  smart  phones  or   tablets  as  a  mobile  service.  also,  later  in  the  survey  several  respondents  mention  communication   issues  as  an  ongoing  challenge  in  offering  mobile  services,  specifically,  not  always  knowing  what   other  library  departments  are  offering  in  terms  of  mobile  services.  it  is  possible  that  some  survey   respondents  are  not  responsible  for  the  e-­‐book  collection  and  thus  did  not  mention  it  as  a  mobile   service.     another  discrepancy  exists  between  the  results  for  mobile  apps  for  the  library’s  site  (20.2%  for   the  website  visits  versus  38.24%  for  the  survey).  these  results  indicate  that  mobile  apps  for   libraries’  sites  are  more  common  than  we  had  previously  thought.  perhaps  these  apps  are  being   advertised  in  places  other  than  on  the  library’s  website,  and  therefore  a  website  visit  is  not  the   best  way  to  discover  them.     the  website  visits  did  not  look  for  mobile  library  instruction,  mobile  book  renewal,  or  mobile   interlibrary  loan,  but  through  our  website  visits  we  saw  these  services  mentioned  several  times   and  thus  included  them  in  the  survey.  they  turned  out  to  be  somewhat  common  among  libraries   surveyed;  41.18%  of  respondents  offer  mobile  book  renewal,  20.59%  offer  mobile  interlibrary   loan,  and  32.35%  offer  mobile-­‐friendly  library  instruction.     table  2  below  compares  the  data  collected  from  both  the  website  visits  and  the  survey  among   these  100  universities,  ranking  from  high  to  low  percentages.  in  most  cases,  they  are  very  similar.         information  technologies  and  libraries  |  june  2015   141     mobile  services   percentage  of   libraries

 comparison  of  specific  mobile  services  between  website  visits  &  survey.   what content do the mobile sites offer? in addition to assessing whether libraries had a mobile site, the survey asked libraries that already have a mobile site what is included on the site. 100% of libraries with mobile sites include library hours on their site, making this the most common feature. the next two most common features are library contact information and a search function for the catalog, which both received 96.67%. searching within mobile-friendly databases , such as ebscohost mobile, jstor and pubmed, is the next most popular feature, although it trailed a little behind library hours, contact information, and catalog searching at 70%. book renewal received 56.67%, and access to patron accounts received 53.33%. interlibrary loan is the least common feature by far, offered by only 26.67% of respondents. this information is summarized in chart 2 below: chart  2.  components  of

 and  briggs  |  doi:  10.6017/ital.v34i2.5650   142   these  results  are  interesting  as,  overall,  they  reflect  higher  percentages  for  specific  mobile   services  than  question  1  on  the  survey,  which  asked  which  mobile  services  libraries  offer.  for   example,  in  question  1,  88.24%  of  respondents  offer  mobile  access  to  the  library’s  catalog,   whereas  for  libraries  with  mobile  sites,  96.67%  offer  access  to  the  catalog  on  the  mobile  site.  the   ability  to  search  mobile-­‐friendly  versions  of  databases  the  library  subscribes  to  was  almost  the   same  for  both  groups,  with  70.59%  of  respondents  to  question  1  offering  this  and  70%  of   respondents  having  this  as  a  component  of  their  mobile  sites.  mobile  book  renewal  is  much  more   common  among  libraries  with  mobile  sites;  56.67%  of  respondents  with  mobile  sites  compared  to   41.18%  of  total  respondents.  a  slightly  higher  percentage  of  respondents  with  mobile  sites  offer   mobile  interlibrary  loan  (26.67%)  compared  to  all  respondents  (20.59%).  this  data  suggests  that,   on  the  whole,  libraries  with  mobile  sites  are  more  likely  to  offer  other  mobile  services  as  well,   specifically  mobile  access  to  the  catalog,  mobile  book  renewal,  and  mobile  interlibrary  loan.     what  mobile  reference  services  do  libraries  provide?   the  survey  also  looked  for  information  on  virtual  and/or  mobile  reference  services.  81.25%  of   survey  respondents  offer  text/sms  messaging,  100%  offer  chat/im,  and  21.88%  offer  reference   services  via  a  social  media  account.  these  results  showing  popular  reference  services  in  these  top   universities  are  summarized  in  chart  3  below:   chart  3.  popular  mobile  reference  services.   chat/im  is  obviously  the  most  popular  method  of  providing  virtual/mobile  reference  services;  all   survey  respondents  offer  this  service.  text/sms  is  also  very  popular,  indicating  that  the  majority   of  libraries  see  value  in  providing  both  despite  their  similar  functions.  the  fact  that  social  media   does  not  compare  favorably  to  either  texting  or  chat/im  services  is  curious  because  most  social   media  platforms  have  a  mobile  version  available  that  libraries  can  take  advantage  of  for  free.   however,  this  may  not  be  the  best  medium  for  reference.  one  respondent  commented  on  this   question,  “our  ‘ask  a  librarian’  service  is  available  from  desktop  facebook,  but  not  on  mobile   facebook.”     22%   81%   100%   social  media   text/sms   chat/im   popular  virtual/mobile  reference  services     information  technologies  and  libraries  |  june  2015   143   what  apps  do  libraries  use  or  provide  for  patrons?   although  the  website  visits  and  survey  results  indicated  that  apps  for  a  library’s  site  are  not  very   common,  both  tools  revealed  that  use  of  apps  for  various  purposes  is  widespread.  the  most   commonly  mentioned  app  is  browzine,  which  is  used  for  accessing  e-­‐journals.  several   respondents  mentioned  apps  developed  in-­‐house  for  using  library  services,  such  as  an  app  for   reserving  a  study  room,  accessing  university  archives,  and  sending  catalog  records  to  a  mobile   device.  another  respondent  stated  that  the  university’s  app  has  a  library  function.  several   respondents  mentioned  vendor-­‐provided  or  third-­‐party  apps,  such  as  apps  for  accessing  pubmed,   sciencedirect,  naxos  music  library,  accessmylibrary  (for  gale  resources),  a  mobile  medical   dictionary,  and  the  american  chemical  society.  one  respondent  noted  that  the  library  loans  ipads   preloaded  with  popular  apps  to  support  student  research  such  as  endnote,  notability,   goodreader,  pages,  numbers,  and  keynote,  among  others.  finally,  these  apps  were  named  at  least   once  as  an  app  libraries  either  use  or  provide  access  to:  iresearch  (for  storing  articles  locally),   boopsie  (for  building  a  library  mobile  app),  ebrary  (for  accessing  e-­‐books),  and  safari  (for   accessing  books  and  videos  online).  these  results  indicate  that  the  use  of  apps  is  fairly  robust  and   diverse  among  these  libraries.  additionally,  from  these  results,  it  seems  more  common  for   libraries  to  use  and/or  provide  apps  created  by  third  parties  than  to  develop  an  in-­‐house  app,   perhaps  due  to  the  expertise  and  expense  involved  in  creating  and  maintaining  an  app.     what  mobile  services  will  be  added  in  the  future?   the  final  question  of  the  survey  asks  libraries  if  there  are  any  plans  to  offer  a  mobile  service  not   currently  provided.  responses  are  summarized  in  chart  4  below.     chart  4.  percentage  of  the  libraries  seeking  to  add  specific  mobile  services   the  most  common  selection  is  mobile  friendly  library  instruction,  with  61.54%.  the  next  most   common  is  a  mobile  website  (46.15%).  mobile  interlibrary  loan  was  chosen  by  38.46%  of   8%   8%   8%   15%

 |     liu  and  briggs  |  doi:  10.6017/ital.v34i2.5650   144   respondents.  less  common  services  planned  include  adding  mobile  access  to  the  library’s  opac,   mobile  access  to  the  library’s  databases,  and  mobile  book  renewal,  each  of  which  were  chosen  by   15.38%  of  respondents.  7.69%  of  respondents  are  planning  to  add  mobile  apps,  e-­‐books,  and   augmented  reality,  respectively.  no  one  indicated  plans  to  add  text  messaging  services  or  qr   codes.  these  results  indicate  that  libraries  expect  demand  for  traditional  library  services  in  a   mobile-­‐friendly  format  to  continue  to  expand;  mobile  friendly  library  instruction  was  only  offered   by  32.35%  of  respondents,  yet  61.54%  have  plans  to  offer  this  service  in  the  future.  mobile   interlibrary  loan  is  currently  offered  by  20.59%  of  respondents,  so  the  fact  that  38.46%  would  like   to  add  it  represents  a  significant  change.     not  surprisingly,  mobile  websites  are  likely  to  remain  a  very  popular  mobile  service.  the  fact  that   82.35%  of  respondents  already  have  a  mobile  website  and  46.15%  who  do  not  have  one  wish  to   add  one  in  the  near  future  means  that  mobile-­‐friendly  sites  are  well  on  their  way  to  becoming   ubiquitous,  at  least  among  libraries  at  the  top  100  universities,  and  may  reasonably  be  expected  to   take  their  place  among  websites  in  general  as  a  necessity  to  maintain  institutional  viability.   additionally,  several  respondents  mentioned  moving  towards  responsive  design,  in  which  their   websites  are  fully  functional  regardless  of  whether  they  are  accessed  on  mobile  devices  or   desktops.   what  are  challenges  and  strategies  for  offering  mobile  services?   in  addition  to  looking  for  the  presence  or  absence  of  mobile  services  being  offered  at  top  100   university  libraries,  the  survey  also  examined  libraries’  experiences  in  implementing  mobile   services,  including  challenges,  successes,  and  best  practices.  several  themes  emerged  in  response   to  these  questions.  the  most  common  challenge  among  respondents  was  having  the  time,   expertise,  staffing  and  money  to  support  mobile  services,  especially  apps  and  mobile  sites.  to   solve  this  problem,  respondents  mention  relying  on  vendors  and  third-­‐party  providers  supplying   apps  to  access  their  resources,  but  this  does  not  give  libraries  the  flexibility  and  specificity  of  an   in-­‐house  app.     another  common  challenge  mentioned  by  several  respondents  involved  technical  issues,  such  as   difficulties  with  off  campus  access  to  resources  via  a  proxy  server  and  compatibility  issues  among   different  browsers  and  especially  different  devices.  a  lack  of  communication  and/or  support  is   another  issue  for  libraries.  one  respondent  reported  a  lack  of  support  from  the  campus  computing   center  for  mobile  services.  one  respondent  discussed  the  difficulty  of  having  a  coordinated  mobile   effort  when  the  library  has  a  large  number  of  departments,  and  each  department  may  or  may  not   be  aware  of  what  the  others  are  doing  in  regards  to  mobile  services.  survey  results  revealed  that   few  libraries  have  policies  in  place  to  support  mobile  services.     coming  up  with  a  specific  plan  for  implementing  such  services  can  help  libraries  work  towards   promoting  effective  communication  and  garnering  support.  one  respondent  wrote,  “the  biggest   challenges  have  been:  (1)  developing  a  strategy  (2)  developing  a  service  model  (3)  having  a   systematic  model  for  managing  content  for  both  mobile-­‐  and  non-­‐mobile  applications.  we've  had     information  technologies  and  libraries  |  june  2015   145   success  with  the  first  two  and  are  making  great  progress  on  the  third.”  interestingly,  several   respondents  noted  that  underuse  is  an  issue  for  some  services.  one  respondent  mentioned  that   qr  codes  are  not  used  often,  and  another  mentioned  that  the  library’s  text-­‐a-­‐librarian  service  is   much  underutilized.  several  respondents  cited  the  need  to  market  mobile  services  as  an  antidote   to  this  problem.  seeking  regular  feedback  from  the  user  community  regarding  mobile  services   wants  and  needs  is  another  recommended  solution.   other  issues  include  the  fact  that  not  all  library  services  are  mobilized.  however,  libraries  are   actively  looking  for  solutions  for  this.  there  is  a  trend  among  respondents  towards  developing  a   site  that  is  responsive  to  all  devices,  including  desktops,  laptops,  tablets,  and  phones.  this  will  take   the  place  of  a  separate  mobile  site.  as  one  respondent  states,  “at  the  moment,  our  library  mobile   website  only  has  a  fraction  of  the  services  available  via  our  desktop  website.  we  are  in  the  process   of  moving  everything  to  responsive  design,  with  the  expectation  that  all  services  will  be  equally   available  in  mobile  and  desktop.”  in  reading  through  these  responses,  one  message  is  clear:  mobile   services  are  a  must.  several  respondents  noted  that  demand  for  mobile  services  is  growing,  with   one  writing,  “get  started  as  soon  as  possible.  our  analytics  show  that  mobile  use  is  continuing  to   increase.”   conclusion   this  study  confirms  that  as  of  spring  2014  mobile  services  are  already  ubiquitous  among  the   country’s  top  100  universities’  libraries  and  are  likely  to  continue  to  grow.  where  the  most   common  services  offered  are  e-­‐books,  chat/im,  mobile  access  to  databases,  mobile  access  to  the   library  catalog,  mobile  sites,  and  text  messaging  services,  there  is  a  trend  towards  responsive   design  for  websites  so  that  patrons  can  access  the  library’s  full  site  on  any  mobile  device.       the  experiences  of  these  libraries  demonstrate  the  value  of  creating  a  plan  for  providing  mobile   services,  allotting  the  appropriate  amount  of  staffing,  time,  and  funding,  communicating  among   departments  and  stakeholders  to  coordinate  mobile  efforts,  marketing  services,  and  regularly   seeking  patron  feedback.  however,  there  is  no  one  approach  to  offering  mobile  services,  and  each   library  must  do  what  works  best  for  its  patrons.   references     1.     andrew  walsh,  using  mobile  technology  to  deliver  library  services  (maryland:  scarecrow   press,  2012),  xiv.   2.     “smartphone

libraries across states from 2004 to 2006. based on library-supplied information about levels and types of internet and public computing access, the authors offer insights into the network-based content and services that public libraries provide. examining data from 2004 to 2006 reveals trends and accomplishments in certain states and geographic regions. this paper details and discusses the data, identifies and analyzes issues related to internet access, and suggests areas for future research. t his article presents findings from the 2004 and 2006 public libraries and the internet studies detail­ ing the different levels of internet access available in public libraries in different states.1 at this point, 98.9 percent of public library branches are connected to the internet and 98.4 percent of connected public library branches offer public internet access.2 however, the types of access and the quality of access available are not uniformly distributed among libraries or among the libraries in various states. while the data at the national level paint a portrait of the internet and public computing access provided by public libraries overall, studies of these differences among the states can help reveal successes and lessons that may help libraries in other states to increase their levels of access. the need to continue to increase the levels and quality of internet and public computing access in public libraries is not an abstract problem. the services and con­ tent available on the internet continue to require greater bandwidth and computing capacity, so public libraries must address ever­increasing technological demands on the internet and computing access that they provide. 3 public libraries are also facing increased external pressure on their internet and computing access. as patrons have come to rely on the availability of internet and computing access in public libraries, so too have government agencies. many federal, state, and local government agencies now rely on public libraries to facilitate citizens’ access to e­government services, such as applying for the federal prescription drug plans, filing taxes, and many other interactions with the gov­ ernment.4 further, public libraries also face increased demands to supply public access computing in times of natural disasters, such as the major hurricanes of 2004 and 2005.5 as a result, both patrons and govern­ ment agencies depend on the internet and computing access provided by public libraries, and each group has different, but interrelated, expectations of what kinds of access public libraries should provide. however, the data indicate that public libraries are at capacity in meet­ ing some of these expectations, while some libraries lack the funding, technology­support capacity, space, and infrastructure (e.g., power, cabling) to reach the expecta­ tions of each respective group. as public libraries (and the internet and public com­ puting access they provide) continue to fill more social roles and expectations, a range of new ideas and strate­ gies can be considered by public libraries to identify suc­ cessful methods for providing access that is high quality and sufficient to meet the needs of patrons and commu­ nity. the goals of the public libraries and the internet stud­ ies have been to help provide an understanding of the issues and needs of libraries associated with providing internet­based services and resources. the 2006 public libraries and the internet study employed a web­based survey approach to gather both quantitative and qualitative data from a sample of the 16,457 public library outlets in the united states.6 a sample was drawn to accurately represent metropolitan status (roughly equating to their designation of urban, suburban, or rural libraries), poverty levels (as derived through census data), state libraries, and the national picture, producing a sample of 6,979 public library out­ lets.7 the survey received a total of 4,818 responses for a response rate of 69 percent. the data in this article, unless otherwise noted, are drawn from the 2004 and 2006 public libraries and the internet studies.8 while the survey received responses from librar­ ies in all fifty states, there were not enough responses in all states from which to present state­level findings. the study was able to provide state­level analysis for thirty­five states (including washington, d.c.) in 2004 and forty­four states at the outlet level (including washington, d.c.) and forty­two states at the system level (including washington, d.c.) in 2006. in addi­ tion, there was some variance in states with adequate responses between the 2004 and 2006 studies. a full listing of the states is available in the final reports of the 2004 and 2006 studies at http://www.ii.fsu.edu/ plinternet_reports.cfm. thus, the findings below reflect 4 information technology and libraries | june 2007 public libraries and internet

states overview of 2004 to 2006 as the public library and the internet studies have been ongoing since 1994, the questions asked in the biennial studies have evolved along with the provision of internet access in libraries. the questions have varied between surveys, but there have been consistent questions that allow for longitudinal analysis at the national level. the 2004 study introduced the analysis of the data at both the national and the state levels. with both the 2004 and 2006 studies providing data at the state level, some longitudi­ nal analysis at the state level is now possible. overall, there were a number of areas of consistent data across the states from 2004 to 2006. most states had fairly similar, if not identical, percentages of library outlets offering public internet access between 2004 and 2006. for the most part, changes were increases in the percentage of library outlets offering patron access. further, the average number of hours open per week in 2004 (44.5) and in 2006 (44.8) were very similar, as were the percentages of library outlets reporting increases in hours per week, decreases in hours per week, and no changes in hours per week. while these numbers are consistent, it is not known whether this average number of hours open, or the distribution of the hours open across the week, is sufficient to meet patron needs in most communities. data across the states also indicated that physical space is the primary reason for the inability of libraries to add more workstations within the library building. there was also consistency in the findings related to upgrades and replacement schedules. changes and continuities from 2004 to 2006 while the items noted above show some areas of stability in the internet access provided by public libraries across the states, insights are possible in the areas of change for libraries overall or in the libraries that are leading in particular areas. table 1 details the states with the highest average number of hours open per public library outlet in 2004 and 2006. between 2004 and 2006, the national average for the number of hours open increased slightly from 44.5 hours per week to 44.8 hours per week. this increase is reflected in the numbers for the individual states in 2006, which are generally slightly higher than the numbers for the individual states in 2004. for example, the top state in 2006 averaged 55.7 hours per outlet each week, while the top state in 2004 averaged 54.8 hours. the top four states—ohio, new jersey, florida, and virginia—were the same in both years, though with the top two switching positions. this demonstrates a continuing commitment in these four states by state and local government to ensure wide access to public librar­ ies. these states are also ones with large populations and state budgets, presumably fueling the commitment and facilitating the ability to keep libraries open for many hours each week. while the needs of patrons in other states are no less significant, the data indicate that states with larger populations and higher budgets, not surpris­ ingly, may be best positioned to provide the highest levels of access to public libraries for state residents. the other six states in the 2006 top ten were not in the 2004 top ten. the primary reason for this is that the six states in 2006 increased their hours more than other states. note that the fifth­ranked state in 2004, south carolina, averaged 49 hours per outlet each week, which is less than the tenth­ranked state in 2006, illinois, at 49.5 hours. simply by maintaining the average number of hours open per outlet between 2004 and 2006, south carolina fell from fifth to out of the top ten. these differ­ ences are reflected in the fact that there is nearly a ten­ hour difference from first place to tenth place in 2004; yet only a six­hour discrepancy exists from first place to tenth in 2006. these numbers suggest that hours of operation may change frequently for many libraries, indicating the need for future evaluations of operational hours in rela­ tion to meeting patron demand. table 2 displays the states with the highest average number of public access workstations per public library in 2004 and 2006. the national averages between 2004 and 2006 also showed a slight increase from 10.4 workstations table 1. highest average number of

new york 46.2 10. illinois 49.5 national: 44.5 national: 44.8 in 2004 to 10.7 workstations in 2006. a key reason for this slow growth in the number of workstations appears to have a great deal to do with limitations of physical space in libraries; in spite of increasing demands, space con­ straints often limit computer capacity.9 unlike table 1, the comparisons between 2004 and 2006 in table 2 do not show across­the­board increases from 2004 to 2006. in fact, florida had the highest average of workstations per library outlet in both 2004 and 2006, but the average number decreased from 22.6 in 2004 to 21.7 in 2006. it is interesting to note that florida has a significantly higher number of workstations than the next highest state in both 2004 and 2006. in contrast, many of the states in the lower half of the top ten in 2004 had sub­ stantially lower average numbers of workstations in 2004 than in 2006. in 2004 there were an average of seven more computers in spot two than spot ten; in 2006, there were only an average of four more computers from spot two to ten. the large increases in the number of workstations in some states, like nevada, michigan, and maryland, indicate sizeable changes in budget, numbers of outlets, and/or population size. also of note is the significant drop of the average number of workstations in kentucky, declining from 18.8 in 2004 to fewer than 13 in 2006. a possible explanation is that, since kentucky libraries have been leaders in adopting wireless technologies (see table 3), the demand for workstations has decreased as libraries have added wireless access. five states appear in the top ten of both years— florida, indiana, georgia, california, and new jersey. the average number of workstations in indiana, california, and georgia increased from 2004 to 2006, while the aver­ age number of workstations in florida and new jersey decreased between 2004 and 2006. some of the decreases in workstations can be accounted for by increases in the availability of wireless access in public libraries, as librar­ ies with wireless access may feel less need to add more networked computers, relying on patrons to bring their own laptops. such a strategy, of course, will not increase access for patrons who cannot afford laptops. some libraries have sought to address this issue by having lap­ tops available for loan within the library building. the states listed in table 3 had the highest average levels of wireless connectivity in public library outlets in 2004 and 2006. the differences between the numbers in 2004 and 2006 reveal the dramatic increases in the avail­ ability of wireless internet access in public libraries. the national average in 2004 was 17.9 percent, but in 2006, the national average had more than doubled to 37.4 percent of public libraries offering wireless internet access. this sizeable increase is reflected in the changes in the states with the highest levels of wireless access. every position in the ratings in table 3 shows a dra­ matic jump from 2004 to 2006. the top position increased from 47 percent to 63.8 percent. the tenth position increased from 19.6 percent to 47.8 percent, an increase of nearly two­and­a­half times. these increases show how much more prominent wireless internet access has become in the services that public libraries offer to their communities and to their patrons. four states appear on both the 2004 and 2006 lists— virginia, kentucky, rhode island, and new jersey. these four states all showed increases, but the rises in some table 2.

states were significant enough to reduce kentucky from the top­ranked state in 2004 to the fifth ranked, in spite of the fact that the number of public libraries in kentucky offering wireless access increased from 47 per­ cent to 52 percent. in both years, a majority of the states in the top ten were located along the east coast. further, high levels of wireless access may be linked in some states to areas of high population density or the strong presence of technology­related sectors in the state, as in california and virginia. smaller states with areas of dense popula­ tions, such as connecticut, rhode island, and maryland, are also among the leaders in wireless access. tables 4 and 5 provide contrasting pictures regarding the number of public access internet workstations in public libraries by state in 2004 and 2006. table 4 shows the states with the highest percentages of libraries that consistently have fewer workstations that are needed by patrons, while table 5 shows the states with the highest percentages of libraries that consistently have sufficient workstations to meet patron needs. of note is the fact that, unlike the preceding three tables, there appears to be no significant geographical clustering of states in tables 4 and 5. nationally, the percentage of libraries that consis­ tently have insufficient workstations to meet patron needs declined from 15.7 percent in to 2004 to 13.7 percent in 2006, a change that is within the margin of error (+/­ 3.4 percent) of the question on the 2006 survey. due to the size of the change, it is not known if the national decline was a real improvement or simply a reflection of the margin of error. washington, d.c., oregon, new mexico, idaho, and california appear on the lists for both 2004 and 2006 in table 4. washington, d.c. had the highest percentage of libraries reporting insufficient workstations in both years, though there was a significant decrease from 100 percent of libraries in 2004 to 69 percent of libraries in 2006. in this case, the significant drop represents major strides forward to providing sufficient access to patrons in washington, d.c. similarly, though california features on both lists, the percentages dropped from 44.9 percent in 2004 to 22.2 percent in 2006, a decline of more than half. states like these are obviously making efforts to address the need for increased workstations. overall, eight out of ten positions in table 4 remained constant or saw a decline percentage in each position from 2004 to 2006, indicating a national decrease in libraries with insufficient workstations. in sharp contrast, fewer than 20 percent of nevada libraries in 2004 reported insufficient workstations, placing well out of the top ten. however, in 2006 nevada ranked second, with 51.5 percent of public libraries reporting insufficient workstations to meet patron demand. with nevada’s rapidly growing population, it appears that the demand for internet access in public libraries may not be keeping pace with the population growth. the percentage of public libraries reporting suffi­ cient workstations to consistently meet patron demands increased slightly at the national level from 14.1 percent in 2004 to 14.6 percent in 2006, again well within the margin of error (+/­ 3.5 percent) of the 2006 question. however, in table 5, the top ten positions in 2006 all fea­ ture lower percentages than the same positions in 2004. in 2004 the top­ranked state had 53.2 percent of libraries able to consistently meet patron needs for internet access, but the top­ranked state in 2006 had only 31 percent of libraries able to consistently meet patron access needs. table 4. public library outlet public access workstation availability by state in 2004 and

pennsylvania 17.9% west virginia 17.9% national: 14.1% national: 14.6% � information technology and libraries | june 2007 four states—new hampshire, arkansas, wyoming, and vermont—appear on both the 2004 and 2006 lists. the national increase in the sufficiency of the num­ ber of workstations to meet patron access needs and decreases in all of the top­ranked states between 2004 and 2006 seems incongruous. this situation results, however, from a decrease in range of differences among the states from 2004 to 2006, so that the range is compressed and the percentages are more similar among the states. further, in some states, the addition of wireless access may have served to increase the overall sufficiency of the access in libraries, possibly leveling the differences among states. nevertheless, the national average of only 14.6 percent of public libraries consistently having sufficient numbers of workstations to meet patron access needs is clearly a major problem that public libraries must work to address. comparing the 2006 data of tables 4 and 5 demonstrates that patron demands for internet access are being met neither evenly nor consistently across the states. nationally, the percentage of public library systems with increases in the information technology budgets from the previous year dropped dramatically from 36.1 percent in 2004 to 18.6 percent in 2006. as can be seen in table 6, various national, state, and local budget crunches have significantly reduced the percentages of public library systems with increases in information technology budgets. when inflation is taken into account, a stationary information technology budget represents a net decrease in funds available in real dollar terms, so the only public libraries that are not actually having reductions in their information technology budgets are those with increases in such budgets. since internet access and the accompa­ nying hardware necessary to provide it are clearly a key aspect of information technology budgets, decreases in these budgets will have tangible impacts on the ability of public libraries to provide sufficient internet access. virtually every position on table 6 has a decrease of 20 percent to 30 percent from 2004 to 2006, with the largest decrease being from 84.2 percent in 2004 to 48.3 percent in 2006 in the second position. five states—delaware, kentucky, florida, rhode island, and south carolina—are listed for both 2004 and 2006, though every one of these states registered a decrease from 2004 to 2006. no drop was more dramatic than south carolina’s from 84.2 percent in 2004 to 31 percent in 2006. overall, though, the declining information tech­ nology budgets and continuing increases in demands for information technology access among patrons cre­ ates a very difficult situation for libraries. public libraries and the internet in 2006 along with questions that were asked on both the 2004 and 2006 public libraries and the internet studies, the sur­ vey included new questions on the 2006 study to account for social changes, alterations of the policy environment, and the maturation of internet access in public librar­ ies. several findings from the new questions on the 2006 study were noteworthy among the state data. the states listed in table 7 had the highest percentage of public library systems with increases in total operating budget over the previous year in 2006. nationally, 45.1 percent of public library systems had some increase in their overall budget, which includes funding for staff, physical structures, collection development, and many other costs, along with technology. at the state level, three northeastern states clearly led the way, with more than 75 percent of library systems in maryland, delaware, and rhode island benefiting from an increase in the overall operating budget. also of note is the fact that two fairly table 6. highest levels of public library system overall

45.1% public libraries and internet access | jaeger, bertot, mcclure, and rodriguez � rural and sparsely populated western states—idaho and wyoming—were among the top ten. five of the states in the top ten in highest percent­ ages of increases in operating budget in 2006 were also among the top ten in highest percentages of increases in information technology budgets in 2006. comparing table 7 with table 6 reveals that delaware, kentucky, maryland, rhode island, and wyoming are on both lists. in these states, increases in information technology budgets seem to have accompanied larger increases in the overall 2006 budget. an interesting point to ponder in comparing table 6 with table 7 is the large discrepancy between average increases in information technology budgets (18.6 per­ cent) with overall budgets (45.1 percent) at the national level. as internet access is becoming more vital to pub­ lic libraries in the content and services they provide to patrons, it seems surprising that such a smaller portion of library systems would receive an increase in information technology budgets than in overall budgets. one growing issue with the provision of internet access in public libraries is the provision of access at suf­ ficient connection speeds. more and more internet con­ tent and services are complex and require large amounts of bandwidth, particularly content involving audio and video components. fortunately, as demonstrated in table 8, 53.5 percent of libraries nationally indicate that their connection speed is sufficient at all times to meet patron needs. in contrast, only 16.1 percent of public libraries nationally indicate that their connection speed is insuf­ ficient to meet patron needs at all times. georgia has the highest percentage of libraries that always have sufficient connection speed at 80.5 percent. in the case of georgia, the statewide library network is most likely a key part of ensuring the majority of libraries have sufficient access speed. many of the other states that have the highest percentages of public librar­ ies with sufficient connection speeds are located in the middle part of the country. the state with the highest percentage of libraries with insufficient connection speed to meet patron demands is virginia, with 35 per­ cent of libraries. curiously, virginia consistently ranks in the top ten of tables 1–3. though virginia libraries have some of the longest hours open, some of the high­ est numbers of workstations, and some of the highest levels of wireless access, they still have the highest per­ centage of libraries with insufficient connection speed. only five states had more than 25 percent of libraries with connection speeds insufficient to meet the needs of patrons at all times. this issue is significant now in these states, as these libraries lack the necessary connec­ tion speeds. however, it will continue to escalate as an issue as content and services on the internet continue to evolve and become more complex, thus requiring greater connection speeds. comparing table 8 with table 4 (consistently have fewer workstations than are needed) and table 5 (always have a sufficient number of workstations to meet demand) reveals some parallels. alabama and rhode island are among the top ten states both for connection speed being consistently insufficient to meet patron needs (table 8) and consistently have fewer workstations than are needed (table 4). conversely, vermont and louisiana are among the top ten states both for connection speed being sufficient to meet patron needs at all times (table 8) and always have a sufficient number of workstations to meet demand (table 5). table 9 displays the two leading types of internet connection providers for public libraries and the states with the highest percentages of libraries using each. nationally, 46.4 percent of public libraries rely on an internet service provider (isp) for internet access. in the states listed in table 9, three­quarters or more of librar­ ies use an isp, with more than 90 percent of libraries in kentucky and iowa using an isp. the next most common means of connection for public libraries is through a library cooperative or library network, with 26.2 percent of libraries nationally using these means. in such cases, member libraries rely on their established network to serve as the connector to the internet. the library net­ work approach seems to be most effective in geographi­ cally small states. the top three on the list being three of the smallest of the states—rhode island, delaware, and west virginia—with more than 75 percent of libraries in each of these states connecting through a network. nationally, the remaining approximately 25 percent of table �. highest

of public library sys­ tems receiving each kind of e­rate discount are presented in table 10. e­rate discounts are an important source of technology funding for many public libraries across the country, with more than $250,000,000 in e­rate discounts distributed to libraries between 2000 and 2003.10 nationally in 2006, 22.4 percent of public library systems received discounts for internet connectivity, 39.6 percent for telecommunications services, and 4.4 percent for internal connection costs. mississippi and louisiana appear in the top five for each of the three types of discounts. minnesota and west virginia are each in the top five for two of the three lists. many of the states benefiting the most from e­rate funding in 2006 have large rural popu­ lations spread out over a geographically dispersed area, indicating the continuing importance of e­ rate discounts in bringing internet connections to rural public libraries. maryland and west virginia are both included in the telecommunications service column of table 10 due to proportionally large areas of these smaller states that are rural. the importance of the telecommunications dis­ counts in certain states is obviated by the fact that more than 75 percent of public library systems in all five states listed received such discounts. in comparison, only one state has more than 75 percent of library systems receiv­ ing discounts for internet connectivity, while no state has 30 percent of library systems receiving discounts for internal connection costs, with the latter reflecting the manner in which e­rate funding is calculated. in spite of the penetration of the internet into virtually every public library in the united states and the general expectations that internet access will be publicly available in every library, not all public libraries offer information technology training for patrons. nationally, 21.4 percent of public library outlets do not offer technology training. table 10 lists the states with the highest percentages of public library outlets not offering information technol­ ogy training. six of the ten states listed are located in the southeastern part of the country. the lack of resources or adequate number of staff to provide training is a leading concern in these states. not offering patron training may be strongly linked to lacking economic resources to do so. for example, the two states with the highest percentage of public libraries not offering patron training—mississippi and louisiana—are also the two states in the top five recipients of each kind of e­rate funding listed in table 10. if the libraries in states like these are economically struggling just to provide internet access, it seems likely that providing accompany­ ing training might be difficult as well. a further difficulty is that there is little public or private funding available specifically for training. n discussion of issues the similarities and differences among the states indi­ cate that the evolution of public access to the internet in public libraries is not necessarily an evenly distributed phenomenon, as some states appear to be consistent lead­ ers in some areas and other states appear to consistently trail in others. while the national picture is one primarily of continued progress in the availability and quality of internet access available to library patrons, the progress is not evenly distributed among the states. 11 libraries in different states struggle with or benefit from different issues. some public libraries are limited by state and local budgetary limitations, while other libraries are seeking alternate funding sources through grant writ­ ing and building partnerships with the corporate world. some face barriers to providing access due to their geo­ graphical location or small service population. it may also be the case that the libraries in some states do not per­ ceive that patrons desire increased access. other public libraries are able to provide high­end access as a result of having strong local leadership, sufficient state and local funding, well­developed networks and cooperatives, and a proactive state library. though the discussion of the “digital divide” has become much less frequent, the state data seem to indi­ cate that there are gaps in levels of access among libraries in different states. while every state has very successful individual libraries in terms of providing quality internet table �. highest levels of types of internet connection provider for public library outlets by state

a better job, the state data indicate that library patrons in different parts of the country have variations in the levels and quality of access available to them. uniformity across all states clearly will never be feasible, though, as differ­ ent states and their patrons have different needs. for example, tables 1, 2, and 3 all display features that indicate high­level internet access in public librar­ ies—high numbers of hours open, high numbers of public access workstations, and high levels of wireless internet access. three states—maryland, new jersey, and virginia—appear in the top ten in these three lists for 2006. further, connecticut, florida, illinois, and indiana each appear in the top ten of two of these three lists. these states clearly are making successful efforts at the state and local levels to guarantee widespread access to public libraries and the internet access they provide. gaps in access are also evident among different regions of the country. the highest percentages of library systems with increases in total operating budgets were concentrated in states along the east coast, with seven of the states listed in table 7 being mid­atlantic or northeastern states. in con­ trast, the highest percentages of library systems relying on e­rate funding in table 10 were concentrated in the midwest and the southeast. further, the numbers in tables 6 and 7 showed far greater increases in the total operating budgets than in the information technology budgets in all regions of the country. as a result, public libraries in all parts of the united states may need to seek alternate sources of funding specifically for information technology costs. as can be seen in table 3, the leading states in adoption of wireless technology are concentrated in the northeast and mid­atlantic. in table 11, southern states, particu­ larly louisiana and mississippi, had many of the highest percentages of libraries not offering any internet training to patrons. it is important to note with data from the gulfstates, however, that the effects of hurricane katrina may have had a large impact on the results reported. one key difference in a number of states seems to be the presence of a state library actively working to coordi­ nate access issues. this particular study was not able to address such issues, but evidence indicates that the state library can play a significant role in ensuring sufficiency of internet access in public libraries in a state. maine, west virginia, and wisconsin all have state libraries that apply and distribute funds at the statewide level to ensure all public libraries, regardless of size or geography, have high­end connections to the internet. the state library of west virginia, for example, applied for e­rate funding for telecommunications costs on a statewide basis and received 79.1 percent funding in 2006, using such funding to cover not only connection costs for public libraries, but also to provide it and network support to libraries. another example of a successful statewide effort to provide sufficient internet access can be found in maryland. in the early 1990s, maryland public library administrators agreed to let the state library use library services and technology act (lsta) funds to build the sailor network, connecting all public libraries in the state.12 this network predates the e­rate program by a number of years, but having an established statewide network has helped the state library to coordinate table 10. highest percentages of public library systems receiving e-rate

information technology and libraries | june 2007 applications, funding, and services among the libraries of the state. the state budget in maryland also provides other types of funding to support the state library, the library systems, and the library outlets in providing internet access. in states such as georgia, maryland, maine, west virginia, and wisconsin, the provision of internet access in public libraries is shaped not only by library outlets and library systems, but by the state libraries as well. in these and other states, the efforts of the state library appear to be reflected in the data from this study. a final area for discussion is the degree to which librarians understand how much bandwidth is required to meet the needs of library users, how to measure actual bandwidth that is available in the library, and how to determine the degree to which that bandwidth is suf­ ficient. indeed, many providers advertise that their con­ nection speeds are “up to” a certain speed when in fact they deliver considerably less.13 the authors have offered an analysis of determining the quality and sufficiency of bandwidth elsewhere.14 suffice to say that there is consid­ erable confusion as to “how good is good enough” band­ width connection quality. these types of issues frame understandings of how connected libraries in different states are and whether those connections are sufficient to meet the needs of patrons. n future research while the experience of individual patrons in particular libraries will vary widely in terms of whether the access available is sufficient to meet their information needs, the fact that the state data indicate variations in the levels and quality of access among some states and regions of the country is worthy of note. an important area of sub­ sequent research will be to investigate these differences, determine the reasons for them, and develop strategies to alleviate these apparent gaps in access. investigating these differences requires consideration of local and situational factors that may affect access in one library but perhaps not in another. for example, one public library may have access to an internet provider that offers higher speed connectivity that is not available in another location. the range of the possible local and situational factors affecting access and services is extensive. a prelimi­ nary list of the factors that contribute to being a success­ fully networked public library is described in greater detail in the 2006 study.15 however, additional investigation into the degree to which these factors affect access, quality of service, and user satisfaction needs to be continued. the personal experience of the authors in working with various state library agencies suggests the need for additional research that explores relationships among those states ranked highest in areas such as connectivity and workstations with programs and services offered by the state library agencies. one state library, for example, has a specific program that works directly with individual public libraries to assist them in completing the various e­rate forms. is there a link between that state library providing such assistance and the state’s public libraries receiving more e­rate discounts per capita than other states? this is but one example where investigating the role of the state library and comparing those roles and services to the rankings may be useful. perhaps a number of “best practices” could be identified that would assist the libraries in other states in improv­ ing access and services. in terms of research methods, future research on the topics identified in this article may need to draw upon strategies other than a national survey and on­site focus groups/interviews. the 2006 study, for the first time, included site visits and interviews and produced a wealth of data that supplemented the national survey data.16 on­site analysis of actual connection speeds in a sample of public libraries is but one example. the degree to which survey respondents know the connec­ tion speeds at specific workstations is unclear. simply because a t­1 line comes in the front door, it is not nec­ essarily the speed available at a particular workstation. other methods such as log file analysis or user­based surveys of networked services (as opposed to surveys completed by librarians) may offer insights that could augment the national survey data. other approaches such as policy analysis may also prove useful in better understanding access, connectiv­ ity, and services on a state­by­state basis. there has been no systematic description and analysis of state­based laws and regulations that affect public library internet access, connectivity, and services. the authors are aware of some states that ensure a minimum bandwidth will be provided to each public library in the state and pay for such connectivity. such is not true in other states. thus, a better understanding of how state­based policies and regulations affect access, connectivity, and services may identify strategies and policies that could be used in other states to increase or improve access, connectiv­ ity, and services. the data discussed in this article also point to many other important needs in future research. libraries in certain states that seem to be frequently ranking high in the tables indicate that certain states are better able to sustain their libraries in terms of finances and usage. however, additional factors may also be key in the differ­ ences among the states. future research needs to consider the internet access in public libraries in different states in relation to other services offered by libraries and to uses of the internet connectivity in libraries, including types of online content and services available, types of training public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 13 available, community outreach, other collection issues, staffing in relation to technology, and other factors. n conclusion internet and public computing access is almost univer­ sally available in public libraries in the united states, but there are differences in the amounts of access, the kinds of access, and sufficiency of the access available to meet patron demands. now that virtually every public library has an internet connection, provides internet access to patrons, and offers a range of public computing access, the attention of public libraries must refocus on ensuring that every library can provide sufficient internet and com­ puting access to meet patron needs. the issues to address include being open to the public a sufficient number of hours, having enough internet access workstations, hav­ ing adequate wireless access, and having sufficient speed and quality of connectivity to meet the needs of patrons. if a library is not able to provide sufficient access now, the situation will only continue to grow more difficult as the content and services on the internet continue to be more demanding of technical and bandwidth capacity. public libraries must also focus on increasing provi­ sion of internet access in light of federal, state, and local governments recently adding yet another significant level of services to public libraries by “requesting” that they provide access to and training in using numerous e­gov­ ernment services. such e­government services include social services, prescription drug plans, health care, disas­ ter support, tax filing, resource management, and many other activities.17 the maintenance of traditional services, the addi­ tion and expansion of public access computing and networked services, and now the addition of a range of e­government services tacitly required by federal, state, and local governments, in combination, risk stretching public library resources beyond their ability to keep up. to avoid such a situation, public libraries, library sys­ tems, and state governments must learn from the library outlets, systems, and states that are more successfully providing sufficient internet access to their patrons and their communities. among these leaders, there are likely models for success that can be identified for the benefit of other outlets, systems, and states. beyond the lessons that can be learned from the most connected, however, there are also practical and logistical issues that remain beyond the control of an individual library and sometimes the entire state, such as geographical and economic factors. ultimately, the analysis of state data offered here sug­ gests that much can be learned from one state that might assist another state in terms of improving connectivity, access, and services. while the data suggest a number of significant discrepancies among the various states, it may be that a range of best practices can be identified from those more highly ranked states that could be employed in other states to improve access, connectivity, and ser­ vices. staff at the various state library agencies may wish to discuss these findings and develop strategies that can then improve access nationwide. providing access to the internet is now as established a role for public libraries as providing access to books. patrons and communities, and now government orga­ nizations, rely on the fact that internet access will be available to everyone who needs it. while there are other points of access to the internet in some communities, such as school media centers and community technology centers, the public library is often the only public access point available in many communities.18 public libraries across the states must continually work to make sure the access they provide meets all of these needs. n acknowledgements the 2004 and 2006 public libraries and the internet studies were funded by the american library association and the bill & melinda

information technology and libraries | september 2011 nancy m. foasberg adoption of e-book readers among college students: a survey understand whether and how students are using e-book readers to respond appropriately. as new media formats emerge, libraries must avoid both extremes: uncritical, hype-driven adoption of new formats and irrational attachment to the status quo. ■■ research context recently introduced e-reader brands have attracted so much attention that it is sometimes difficult to remember that those currently on the market are not the first generation of such devices. the first generation was introduced, to little fanfare, in the 1990s. devices such as the softbook and the rocket e-book reader are well documented in the literature, but were unsuccessful in the market.1 the most recent wave of e-readers began with the sony reader in 2006 and amazon’s kindle in 2007, and thus far is enjoying more success. barnes and noble and borders have entered the market with the nook and the kobo, respectively, and apple has introduced the ipad, a multifunction device that works well as an e-reader. amazon claims that e-book sales for the kindle have outstripped their hardcover book sales.2 these numbers may reflect price differences, enthusiasm on the part of early adopters, marketing efforts on the parts of these particular companies, or a lack of other options for e-reader users because the devices are designed to be compatible primarily with the offerings of the companies who sell them. nevertheless, they certainly indicate a rise in the consumption of e-books by the public, as the dramatic increase in wholesale e-book sales bears out.3 in the meantime, sales of the devices increased nearly 80 percent in 2010.4 with this flurry of activity have come predictions that e-readers will replace print eventually, perhaps even within the next few years.5 books have been published with such bold titles as print is dead.6 however, despite the excitement, e-readers are still a niche market. according to the 2010 pew internet and american life survey, 5 percent of americans own e-book readers. those who do skew heavily to the wealthy and well-educated, with 12 percent having an annual household income of $75,000 or more and 9 percent of college graduates owning an electronic book reader. this suggests that e-book readers are still a luxury item to many.7 to academic librarians, it is especially important to know whether e-readers are being adopted by college students and whether they can be adapted for academic use. e-readers’ virtues, including their light weight, their ability to hold many books at the same time, and the speed with which materials can be delivered, could make them very attractive to students. however, they have many limitations for academic work. most do not provide the ability to copy and paste into another document, have to learn whether e-book readers have become widely popular among college students, this study surveys students at one large, urban, four-year public college. the survey asked whether the students owned e-book readers and if so, how often they used them and for what purposes. thus far, uptake is slow; a very small proportion of students use e-readers. these students use them primarily for leisure reading and continue to rely on print for much of their reading. students reported that price is the greatest barrier to e-reader adoption and had little interest in borrowing e-reader compatible e-books from the library. p ortable e-book readers, including the amazon kindle, barnes and noble nook, and the sony reader, free e-books from the constraints of the computer screen. although such devices have existed for a long time, only recently have they achieved some degree of popularity. as these devices become more commonplace, they could signal important changes for libraries, which currently purchase and loan books according to the rights and affordances associated with print books. however, these changes will only come about if e-book readers become dominant. for academic libraries, the population of interest is college students. their use of reading formats drives collection development practices, and any need to adjust to e-readers depends on whether students adopt them. thus, it is important to research the present state of students’ interest in e-readers. do they own e-readers? do they wish to purchase one? if they do own them, do they use them often and regard them suitable for academic work? the present study surveys students at queens college, part of the city university of new york, to gather information about their attitudes toward and ownership of e-books and e-book readers. because only queens college students were surveyed, it is not possible to draw conclusions about college students in general. however, the data do provide a snapshot of a diverse student body in a large, urban, four-year public college setting. the goal of the survey was to learn whether students own and use e-book readers, and if so, how they use them. in the midst of enthusiasm for the format by publishers, librarians and early adopters, it is important to consult the students themselves, whose preferences and reading habits are at stake. it is also vital for academic libraries to nancy m. foasberg (nfoasberg@qc.cuny.edu) is humanities librarian, queens college, city university of new york, flushing, new york. adoption of e-book readers among college students: a survey | foasberg 109 foundation survey, internet and american life, found that e-readers were luxury items owned by the well educated and well off. in the survey, 5 percent of respondents reported owning an e-reader.12 in the ecar study of undergraduate students and information technology, 3.1 percent of undergraduate college students reported owning an e-book reader, suggesting that college students are adopting the devices at a slower rate than the general population.13 commercial market research companies, including harris interactive and the book industry study group, also have collected data on e-book adoption. the harris interactive poll found that 8 percent of their respondents owned e-readers, and that those who did claimed that they read more since acquiring it. however, as a weighted online poll with no available measure of sampling error, these results should be considered with caution.14 the book industry study group survey, although it was sponsored by several publishers and e-reader manufacturers, appears to use a more robust method. this survey, consumer attitudes toward e-book reading, was conducted in three parts in 2009 and 2010. kelly gallagher, who was responsible for the group that conducted the study, remarks that “we are still in very early days on e-books in all aspects—technology and adoption.” although the size of the market has increased dramatically, the survey found that almost half of all e-readers are acquired as a gift and that half of all e-books “purchased” are actually free. however, among those who used e-books, about half said they mostly or exclusively purchased e-books rather than print. the e-books purchased are mostly fiction (75 percent); textbooks comprised only 11 percent of e-book purchases.15 much of the literature on e-book readers consists of user studies, which provide useful information about how readers might interact with the devices once they have them in hand but provide no information about whether students are likely to use them of their own volition. however, these studies are of interest because they hint at reasons that students may or may not find e-readers useful, important information for predicting the future of e-books. user studies have covered small devices, such as pdas (personal data assistants);16 first-generation e-readers, such as the rocket ebook;17 and more recent e-book readers.18 the results of many recent e-reader user studies have been very similar to studies on the usability of the first generation of e-book readers: the devices offer advantages in portability and convenience but lack good note-taking features and provide little support for nonlinear navigation. amazon sponsored large-scale research on academic uses of e-book readers at universities, such as princeton, case western reserve university, and the university of virginia,19 while other universities, such as northwest missouri state university,20 carried out their own projects limited note-taking capabilities, and rely on navigation strategies that are most effective for linear reading. the format also presents many difficulties regarding library lending. many publishers rely on various forms of drm (digital rights management) software to protect copyrighted materials. this software often prevents e-books from being compatible with more than one type of e-book reader. indeed, because e-book collections in academic libraries predate the emergence of e-book readers, many libraries now own or subscribe to large e-book collections that are not compatible with the majority of these devices. furthermore, publishers and manufacturers have been hesitant to establish lending models for their books. amazon recently announced that they would allow users to lend a book once for a period of fourteen days, if the publisher gave permission.8 this very cautious and limited approach speaks volumes about publishers’ fears regarding user sharing of e-books. several libraries have developed programs for lending the devices,9 but there is no real model for lending e-books to users who already own e-readers. a service called overdrive also provides downloadable collections, primarily of popular fiction, that can be accessed in this manner. however, the collections are small and are not compatible with all devices, including the most popular, the kindle. in the united kingdom, the publisher’s association has provided guidelines under which libraries can lend e-books, which include a requirement that the user physically visit the library to download the e-book.10 clearly, we do not currently have anything resembling a true library lending model for e-reader compatible e-books, especially not one that takes advantage of the format’s strengths. despite the challenges, it is clear that if e-book readers are enthusiastically adopted by students, libraries will need to find a way to offer materials compatible with them. as buczynski puts it, “libraries need to be in play at this critical juncture lest they be left out or sidelined in the emerging e-book marketplace.”11 however, because the costs of participating are likely to be substantial, it is very important to discover whether students are indeed adopting the hardware. few studies have focused on spontaneous student adoption of the devices, although several mention that when students were introduced to e-readers, they appeared to be unfamiliar with the devices and regard them as a novelty. however, e-readers have become more prevalent since many of these studies were conducted. thus this study surveys students to find their attitudes toward e-book readers. ■■ literature review only a few studies have attempted to quantify the popularity of e-readers. as mentioned above, the 2010 pew 110 information technology and libraries | september 2011 their first encounter with an e-book reader.”34 while this is mere anecdote, it, along with the survey results noted above, raises the question of how popular the device really is on college campuses. finally, a third group of studies attempts to predict the future of e-readers and e-books. even before the introduction of e-readers, some saw e-books as the likely future of academic libraries.35 more recently, one report discusses the likelihood of and barriers to e-book adoption. this article concludes that “barriers to e-book adoption still exist, but signs point to this changing within the next two to five years. that, of course, has been said for most of the past 15 to 20 years.”36 still, nelson points out that technologies can become ubiquitous very quickly, using the ipod as an example, and warns libraries against falling behind.37 yet another report puts e-books in the two-tothree-year adoption range and claims that e-books “have reached mainstream adoption in the consumer sector” and that the “obstacles have . . . started to fall away.”38 ■■ method the e-reader survey was conducted as part of queens college’s student technology survey, which also covered several other aspects of students’ interactions with technology. the author is grateful to the center for teaching and learning (in particular, eva fernández and michelle fraboni) for graciously agreeing to include questions about e-readers in the survey and providing some assistance in managing the data. this survey, run through queens college’s center for teaching and learning, was hosted by surveymonkey and was distributed to students through their official e-mail accounts. participants were offered a chance to win an ipod touch as an incentive, but students who did not participate also were offered an opportunity to enter the ipod drawing. the survey was available between april and june 2010. all personally identifying information was removed from the responses to protect student privacy. rather than surveying the entire population about e-readers and e-books, the survey limited most of the questions to students with some experience with the format. of the students who responded to the survey, only 63 (3.7 percent) used e-readers. however, 338 more students identified themselves as users of e-books but did not use e-readers. all other students skipped past the e-book questions and were directed to the next part of the survey. the questions about e-readers fell into several categories. the students were asked about their ownership of devices and which devices they planned to purchase in the future. while they might of course change their minds about future purchases, this is a useful way of measuring whether students regard the devices as desirable. with other e-readers. other types of programs, most notably texas a&m’s kindle lending program,21 and many academic focus groups have also contributed to our knowledge of how students use e-readers. users in nearly every study have praised the portability of these devices. this can be very important to students; users in one study noted that the portability of reading devices allowed them to “reclaim an otherwise difficult to use brief period,”22 and in another, students were able to multitask, doing household chores and studying at the same time.23 adjustable text size and the ability to search for words in the text have also been popular among students, as has the novelty value of these devices. environmental concerns surrounding heavy printing have also been cited as an advantage of e-readers.24 however, the limitations of these devices, some of which are severe in an academic setting, also have been noted. the comments of students at gettysburg college are typical: they liked the e-readers for leisure reading, but found them awkward for classroom use.25 lack of note-taking support was an important drawback for many students. waycott and kukulska-hulme noted that students were much less likely to take notes while reading with a pda than they were with print.26 a study at princeton found that the same was true of students using the kindle,27 and students at northwest missouri state university said they read less with an e-textbook than with a traditional one, although they did not report changes in their study habits.28 despite the ability of many devices to search the text of a book, users in many studies also disliked the inability to skim and browse through the materials as they would with print.29 interestingly, this complaint appeared in studies of all types of e-readers, even those with larger screens. students, in a recent study with the sony reader and ipod touch, noted that these devices did a poor job of supporting pdfs, a standard format for online course materials. the documents were displayed at a very small size and the words were sometimes jumbled.30 whether these drawbacks will prevent students from adopting e-book readers remained to be seen. library and information science (lis) students in a small, week-long study reiterated the problems found in the above studies, but nevertheless found themselves using e-readers extensively and reading more books and newspapers than they had before.31 several of these user studies hint that e-readers are not currently commonplace as far as users often seemed to regard the devices with surprise and curiosity. in some studies, while users were initially attracted to the novelty value of the devices, their enthusiasm dimmed after using the devices and discovering technical problems and limitations.32 one author describes e-readers as “attention getters, but not attention keepers.”33 a study in early 2009, in which students were provided with e-readers, notes that “for the majority of the participants, this was adoption of e-book readers among college students: a survey | foasberg 111 attitudes of students in general, similar surveys should be taken across many campuses in several demographically different areas. researching e-readers is inherently difficult because the landscape is changing very quickly. since the survey began, apple’s ipad became available, prices for dedicated e-readers have dropped dramatically, publishers have become more willing to offer content electronically, and amazon has released a new version of the kindle and has begun taking out television advertisements for it. without a follow-up survey, it is impossible to know whether these events have changed student attitudes. ■■ results and discussion e-reader adoption of the 1,705 students who responded to the survey, 401 say that they read e-books (table 1). most students (338) who use e-books read them on a device other than an e-reader, but 63 say they use a dedicated reader for e-books (table 2). however, when students were asked about the technological devices that they own, only 56 selected e-book readers. perhaps the seven students who use e-book readers but don’t report owning one are sharing or borrowing them, or perhaps they are using a device other than the ones enumerated in the question. aside from table 3, which breaks down the e-reader brands that students own, the following data will be based upon the larger sample of 63 students. the students who read e-books on another device were asked whether they planned to buy an e-reader in the respondents were also asked about their use of e-books. this category includes questions about what kind of reading students use e-books for, how much of their reading uses e-books, and where they are finding their e-books. it was important to learn whether students considered e-book readers appropriate for academic work, and whether they considered the library a potential source for e-books. finally, to assess their attitudes toward e-book readers, students were asked to identify the main benefits and drawbacks of e-book readers. several possibilities were listed, and students were asked to respond to them along a likert scale. a field was also included in which students could fill in their own answers. after 643 incomplete surveys were eliminated, there were 1,705 responses from queens college students. this is about 8 percent of the queens college student body. e-mail surveys always run the risk of response bias, especially when they concern technology. however, students who responded were representative of queens college in terms of sex, age, class standing, major, and other demographic characteristics. the results were compared using a chi-squared test with the level of significance set at 0.05. in some cases, there were too few respondents to test significance properly and comparisons could not be made. please see appendix for the e-reader questions included in the survey instruments. they will be referred to in more depth throughout this article. ■■ survey limitations the survey results may not be generalizable because of the survey’s small sample size. in particular, the 63 respondents who use e-book readers may not be representative of student e-reader owners in general. the survey also relies on self-reporting; no direct observation of student behavior took place. students who do use e-readers may be more comfortable with technology and more likely to respond to e-mail surveys. however, the sample is representative for queens college students, and the percentage of students who own e-book readers is close to the national average at the time the survey was taken (5 percent).39 since only queens college students were surveyed, the results reflect the behavior and attitudes of students at a single large, four-year public college in new york city. the results do not necessarily reflect the experience of students at other types of institutions or in other parts of the united states. the other parts of the technology survey show that qc students are heavy users of technology, so they may adopt new technologies such as e-book readers more quickly than other students. to understand the table 1. e-book use among respondents e-book use number of respondents read e-books 401 (23.5%) do not read e-books 1262 (74.0%) don’t know

they planned to buy an ipad at the same rate as the other students. it is not clear whether these students plan to replace their e-reader or use multiple devices. in either case, while the arrival of the ipad and other tablet devices seems likely to increase the number of students carrying potential e-reading devices, some of its adopters will probably be students who already own e-readers. not surprisingly, students who used e-readers tended to be early adopters of technology in general (table 4).40 compared to the general pool of respondents, they were much more likely to like or love new technologies and much less likely to describe themselves as neutral or skeptical of them. in a chi-squared test, these differences were significant at a level of 0.001. although e-reading devices have existed since the 1990s, the newest, most popular generation of them is so recent that people who own one now are early adopters by definition. compared to the rest of the survey respondents, both e-reader owners and other e-book users were much more likely to identify as early adopters of technology in general. given this trend, the adoption rate of e-readers among students may slow once the early adopters are satisfied. uses of e-books students who used an e-book reader were asked how much of their reading they did with it and whether they used it for class, recreational, or work-related reading (table 5). students without e-readers were asked the same questions about their use of e-books. while it is likely that students who use e-book readers continue to access e-books in other ways, this distinction was made because this survey was designed to study their use of e-readers specifically. because e-reader users were not asked about their use of e-books in other formats, it is not clear whether their habits with more traditional e-book formats differ from those of other students. fewer than half the e-reader users in the study used the device for two-thirds of their reading or more. in the table below, students who did all their reading and those who did about two-thirds of their reading with e-books are combined, because so few claimed to read e-books exclusively. three students with e-readers and future. the majority had no immediate plans to buy one, with those who said they did not plan to acquire one and those who did not know combining for 62.43 percent. 23.67 percent planned to buy one either within the next year or before leaving college, and the remaining 13.91 percent planned to acquire an e-reader after graduating. despite ergonomic disadvantages, many more students are using e-books on some other device, such as a computer or a cell phone, than are loading them on e-readers. furthermore, a large percentage of these students do not plan to buy an e-book reader. the factors preventing these students from buying e-readers will be covered in more detail in the “attitudes toward e-readers” section below. however, it seems likely that a major factor is price, identified by both e-reader owners and non-owners as the greatest disadvantage of these devices. when asked to list the devices they owned, 56 students named some type of e-book reader. among these, the amazon kindle was the most popular (table 3). as expected, e-readers have yet to be adopted by most students at queens college. at the time of this survey, less than 4 percent of respondents owned one. while the rest of the survey shows that these students are highly wired—82 percent own a laptop less than five years old and 93 percent have high-speed internet access at home—this has not translated to a high rate of e-reader ownership. although apple’s ipad, a tablet device that functions as an e-reader among other things, was not yet released at the time of the survey, it may see wider adoption than the dedicated devices. when the survey was originally distributed, this device had been announced but not yet released. overall, 8 percent of students expressed a table 3. e-reader brands owned by students devices owned number of students (% of e-reader owners) amazon kindle 26 (46.4%) barnes & noble nook 14 (25.0%) sony reader 10 (17.9%) other 6 (10.7%) total 56 (100.0%) table 4. e-reader use and self-identification as an early adopter e-reader owners all respondents love or like new technologies 40 (63.5%) 698 (40.9%) neutral or skeptical about new

the very slow adoption of e-books before the introduction of e-readers, and the ergonomic problems with reading from vertical screens. however, students who used e-books without e-readers were much more likely to read e-books for classes. this difference may be due to the sorts of material that are available in each format. although textbook publishers have shown interest in creating e-textbooks for use on devices such as the ipad, there is little selection available for e-readers as yet. when working without e-book readers, however, there is a wide variety of academic materials available in electronic formats, and many textbooks include an online component. academic libraries, including the one at queens college, subscribe to large e-book collections of academic materials. for the most part, these collections cannot be used on an e-reader, but they are available through the library’s website to students with an internet connection and a browser. it is also possible that the e-readers are not well suited to class readings. some past studies, cited above, have found that e-readers do not accommodate functions such as note taking, skimming, and non-sequential navigation very well. since these are important functions for academic work, and both print books and “traditional” e-books are superior in these respects, such limitations may prevent students from using e-readers for classes. the user behaviors reported here do not appear to herald the end of print; in fact, very few students with e-readers use them for all their reading, and over half of the students with e-readers use them for one-third of their reading or less. it is not clear whether students intentionally choose to read some materials in print and others with nine without said they used e-books for all their reading. very few students without e-book readers used e-books for a large proportion of their reading; indeed, 54 percent said they used e-books for less than a third of their reading. differences between the groups were tested for significance using a chi-squared test. note that percentages may not add up to 100 percent, due to rounding. since many studies of e-book readers have found them more suitable for recreational reading than for academic work, users of e-readers were asked to identify the kinds of readings for which they used e-readers and asked to identify all options that they found applicable (table 6). since students were allowed to choose more than one option, the totals are greater than the number of participants. indeed, e-readers were much more likely to be used for recreational reading and other types of e-books far more likely to be used for class. for other types of reading, differences between these groups were not significant. since e-readers have been marketed largely for the popular fiction market and are designed to accommodate casual linear reading, it is not surprising that students who use them are most likely to report using them for leisure reading. in this area they seem to enjoy a strong advantage over more traditional e-book formats read on another device such as a computer or a cell phone. however, the study did not control for the amount of reading that students do. students who use e-readers may be heavier leisure readers in general. further research could clarify whether heavier use of leisure e-reading is due to the devices or the tendencies of those who own them. a large proportion of the students who read e-books without e-readers (65.7 percent) do read e-books for table 5. amount of

114 information technology and libraries | september 2011 from the manufacturer of the e-reader that supports them, this result is not surprising. it suggests that these booksellers have a high degree of power in the market, a potential effect of e-readers that deserves further attention. however, official e-book sellers of the sort mentioned above are not the only option for students seeking digital reading material, since both independent online bookstores and open access repositories such as project gutenberg were used by students. libraries, both public and academic, reached traditional e-book users much more successfully than e-reader users. although many libraries have large e-book collections, there is currently little material for e-readers. despite the existence of a service called overdrive, which provides e-books compatible with some e-readers (excluding the kindle), circulating e-books is challenging, due to a host of technical and legal problems. given this environment, it is not surprising that students without e-readers were more likely to use their public library as a source of e-books than were e-reader users. the queens college campus library, which offers many electronic collections but none that are e-reader-friendly, fared worse; only one student claimed to have used it as a source of e-reader compatible materials. in the free comment field, students mentioned other sources of e-books such as the apple itunes store, the campus bookstore and lulu.com, an online bookseller that also provides self-publishing. several also admitted, unprompted, that they download books illegally. attitudes toward e-readers in the interests of learning what caused students to adopt e-readers or not, the survey used a series of likert-style questions to ask what the students considered the benefits and drawbacks of such devices. strikingly, e-reader owners and non-owners agreed about both the advantages and disadvantages; owning an e-reader did not seem to change most of the things that students value and dislike about it. figure 1 shows the number of students in each group who their e-reader, or whether they are limited by the materials available for the e-reader. the circumstances under which students switch between electronic and print would be an excellent area for future research; is it a matter of what is practically available, or is the e-reader better suited for some texts and reading circumstances than others? sources of e-books the major producers of e-readers are either primarily booksellers, such as amazon and barnes & noble, or are hardware manufacturers who also provide a store where users can purchase e-books, such as sony (or, after the ipad launch, apple). in both models, the manufacturers hope to sell e-books to those who have purchased their devices. they provide more streamlined ways of loading these e-books on their devices, and in some cases use drm to prevent their e-books from being used on competing devices, as well as to inhibit piracy. table 7 shows the sources from which readers with and without e-readers obtain e-books. e-reader users were much more likely than non-users to get their e-books from the official store associated it—that is, the store providing the e-reader, such as amazon, barnes and noble, or sony’s readerstore. there was no significant difference between the two groups’ use of open access or independent sources, but the students who did not use e-readers were much more likely to use e-books from their public library, and while 19.8 percent of students without e-readers used the campus library as a source of e-books, only one student with an e-reader did. since respondents were allowed to choose more than one answer, the results do not sum up to 100 percent. by a wide margin, students who own e-readers are most likely to purchase their e-reading materials from the “official” store; 86 percent cited the official store as a source of e-books. students without e-readers also use these stores more than any other source of e-books, but they are nevertheless far less likely to use them than e-reader users. because it is much easier to buy

and convenience as “very valuable.” as the studies cited above suggest, being able to easily download books, carry them away from the computer, and store many books on a single device are very appealing to students. only the final two features, text-to-speech and special features such as dictionaries, attracted enough “not very valuable” or “not valuable” responses for an inter-group comparison. both groups considered text-to-speech the least valuable feature, but students who did not own e-readers were significantly more likely to consider it a valuable or very valuable feature, perhaps indicating that the users to whom this is important have avoided the devices, which currently support it in a very limited fashion. perhaps, too, students with e-readers rated this feature less useful because of its current limitations. in either case, rated each feature either valuable or very valuable. if the positive features of the devices are ranked based on the percentage of respondents who considered them very valuable, the order is almost the same for students with and without e-readers. for students with e-readers, the features rank as follows: portability, convenience, storage, special functions, and text-to-speech. for those without, convenience ranks slightly higher than portability; all other features rank in the same order. tables 8 and 9 present the results of these questions in more detail. for the sake of brevity, the chi-squared results have been omitted. any differences considered significant in the discussion below are significant at least at the 0.05 level. nearly all e-reader users and a strong majority of other e-book users rated portability, convenience, and storage either “valuable” or “very valuable,” though figure 1. features rated “valuable” or “very valuable” 116 information technology and libraries | september 2011 among respondents suggests that that many of those who do not own an e-book reader are unfamiliar with the technology. since e-readers are primarily sold over the internet, many people have not had a chance to see or handle one, perhaps partly explaining this result. if they become more widespread, this may well change. not surprisingly, respondents who did not own e-readers were significantly more likely to prefer print. however, it is worth noting that even among students who did use e-readers, over a third “agree” or “completely agree” that they prefer print, with another third neither agreeing nor disagreeing. use of e-readers does not appear to indicate hostility toward print. this is consistent with the students’ self-reports of e-reader use; as reported above, over half of the students surveyed use e-readers for one-third of their reading or less. thus, it seems unlikely that most of these students plan to totally abandon print any time soon; rather, e-readers are providing another format that they use in addition to print. as for students who do not use e-readers, over half say they prefer print, but this is far from their most widespread concern; rather, like e-reader owners, they are most likely to cite the cost of the reader or the selection of books available as a drawback of the devices. queens college students considered price the most important drawback of e-readers. for both groups (owners and non-owners), it was the factor most likely to be identified as a concern, and the difference between the it was the only variable listed in the survey for which either the “not very valuable” and “not valuable” responses from either group amounted to a combined total of greater than 10 percent of the respondents in that group. in addition to valuing the same features, e-reader owners and non-owners had similar concerns about the device. figure 2 shows the number of respondents in each group who agreed or completely agreed that the issues listed were one of the main shortcomings of e-book readers. tables 10 and 11 give the responses in more detail. the responses with which the most respondents either agreed or completely agreed were the same: cost of e-reader, selection of e-books, and cost of e-books, in that order. although groups such as the electronic frontier foundation have raised concerns about privacy issues related to e-readers,41 these issues have made little impression on students; both e-reader users and nonusers were in agreement in putting privacy at the bottom of the list. one exception to the general agreement between e-reader users and other e-book readers was concern about eyestrain. the majority (63 percent) of those who do not use e-readers either “completely agree” or “agree” that eyestrain is a drawback, while only 29 percent of e-reader owners did. this was a major concern for early e-readers, leading the current generation of these devices to use e-ink, a technology that resembles paper and is thought to eliminate the eyestrain problem. the disparity table 8. value of

brought up issues such as highlighting, battery life, and the small size of the screen. another student was more confident in the value of e-readers and used this space to proclaim paper books dead. e-book circulation programs finally, students were asked whether they would be interested in checking out e-readers with books loaded on them from the campus library (table 12). as is often the case when a survey asks for interest in a prospective new service, the response was very positive. however, it was expected that many of the students would prefer to download materials for devices that they already own to take advantage of the convenience of e-readers. on the contrary, a high percentage of both types of students expressed interest in checking out e-book readers, but very few wished to check out e-books two groups was not significant. at the time this survey was taken, amazon’s kindle cost close to $300 and barnes and noble’s nook was priced similarly. soon after the survey closed, however, the major e-reader manufacturers engaged in a “price war,” which resulted in the prices of the best-known dedicated readers, amazon’s kindle and barnes and noble’s nook, falling to under $200. given the feeling among survey respondents that the price of the readers is a serious drawback, this reduction may cause the adoption rate to rise. it would be worthwhile to repeat this survey or a similar one in the near future to learn whether the e-reader price war has had any effect upon price-sensitive students. in the pilot survey, students had written in further responses about the drawbacks of e-readers, but not about their benefits. while some of those responses were incorporated into the final survey, a free text field was also added to catch any further comments. few students figure 2. drawbacks with which students “agree” or “completely agree” 118 information technology and libraries | september 2011 ■■ future research although this survey provides some data to help libraries think about the popularity of e-readers among students, many aspects of students’ use of e-readers remain unexplored. further research on how student adoption of e-book readers varies by location and demographics, particularly considering students’ economic characteristics, for a device of their own. even students who owned e-readers were much more likely to express interest in checking out the device than checking out materials to read on it. this preference belies the common assumption that users do not wish to carry multiple devices and prefer to download everything electronically. instead, they were interested in checking out an e-reader from the library. unless the emphasis of the question altered the results, it is somewhat difficult to account for this response. table 10. drawbacks of e-readers, according to e-reader owners completely agree agree neither agree nor disagree disagree completely disagree no response cost of reader 19 (30.16%) 23

students with e-readers would also help libraries and universities to better serve their needs. in particular, while this survey found that students tend to switch between electronic and print formats, little is yet known about when and why they move from one to the other. it will also be important to research the differences between the reading habits of students who own e-readers and those who do not, as this may prove useful in interpreting the survey data about types of reading done with different kinds of e-books. furthermore, since the e-book market changes quickly, continuing to research student adoption of e-readers is also important to monitor student reactions to new developments. ■■ conclusion while many queens college students express an interest in e-readers, and even those who do not own one believe that their portability and convenience offer valuable advantages, only a small percentage of students, many of whom are early adopters of technology in general, actually use one. furthermore, even those who own e-readers do not use them exclusively, and only a third say they prefer it to print. in light of these responses, the proper response to this technology may not be a discussion about whether “paper books are dead” (as one of the survey respondents wrote in the comment field) but how each format is used. research on when, where, and for what purposes students might choose print or electronic has already begun.42 many of the factors that contribute to the niche status of e-readers are changing. competition between manufacturers has brought down the price of the reader itself, and the selection of books available for them is improving. because these were some of the most important problems standing in the way of e-reader adoption for queens college students, e-reader ownership could increase rapidly. the lack of a significant difference between the attitudes of e-reader owners and nonowners merits further emphasis and examination, as it may indicate that price is indeed the major barrier to e-reader ownership. although the prices are lower now than they were when the survey was originally taken, this would present a major concern if e-readers became the expected format in which students read, perhaps even the possibility of a new kind of digital divide. as the future is uncertain, it is important for academic libraries to pay attention to their students’ adoption of e-readers, and to consider models under which they can provide materials compatible with them. however, it is important to remember that such materials would, at present, be accessible to only a small subset of users, many of 120 information technology and libraries | september 2011 20. jon t. rickman et al., “a campus-wide e-textbook initiative,”

president’s message: open access/open data colleen cuddy information technologies and libraries | march 2012 1 i am very excited to write this column. this issue of information technology and libraries (ital) marks the beginning of a new era for the journal. ital is now an open-access, electronic-only journal. there are many people to thank for this transition. the lita publications committee led by kristen antelman did a thorough analysis of publishing options and presented a thoughtful proposal to the lita board; the lita board had the foresight to push for an open-access journal even if it might mean a temporary revenue loss for the division; bob gerrity, ital editor, has enthusiastically supported this transition and did the heavy lifting to make it happen; and the lita office staff worked tirelessly for the past year to help shepherd this project. i am proud to be leading the organization during this time. to see ital go open access in my presidential year is extremely gratifying. as cliff lynch notes in his editorial, “the library profession has been slow to open up access to the publications of its own professional societies, to take advantage of the greater reach and impact that such policies can offer.” as librarians challenge publishers to pursue open-access venues, myself included, i am relieved to no longer be a hypocrite. by supporting open access we are sending a strong message to the community that we believe in the benefits of open access and we encourage other library organizations to do the same. ital will now reach a much broader and larger audience. this will benefit our authors, the organization, and the scholarship of our profession. i understand that while our members embrace open access, not everyone is pleased with an online-only journal. the number of new journals being offered electronically only is growing and i believe we are beginning to see a decline in the dual publishing model of publishers and societies offering both print and online journals. my library has been cutting back consistently on print copies of journals and this year will get only a handful of journals in print. personally, i have embraced the electronic publishing world. in fact, i held off on subscribing to the new yorker until it had an ipad subscription model! i estimate that i read 95 percent of my books and all of my professional journals electronically. the revolution has happened for me and for many others. i know that our membership will adapt and transition their ital reading habits to our new electronic edition and i look forward to seeing this column and the entire journal in its new format. colleen cuddy (colleen.cuddy@med.cornell.edu) is lita president 2011-12 and director of the samuel j. wood library and c. v. starr biomedical information center at weill cornell medical college, new york, new york. mailto:colleen.cuddy@med.cornell.edu president’s message | cuddy 2 earlier this week saw the research works act die. librarians and researchers across the country celebrated this victory as we preserved an important open-access mandate requiring the deposition of research articles funded by the national institutes of health into pubmed central. this act threatened not just research but the availability of health information to patients and their families. as librarians, we still need to be vigilant about preserving open access and supporting open-access initiatives. i would like to draw your attention to the federal research public access act (frpaa, hr 4004). this act was recently introduced in the house, with a companion bill in the senate. as described by the association of research libraries, frppa would ensure free, timely, online access to the published results of research funded by eleven u.s. federal agencies. the bill gives individual agencies flexibility in choosing the location of the digital repository to house this content, as long as the repositories meet conditions for interoperability and public accessibility, and have provisions for long-term archiving. the legislation would extend and expand access to federally-funded research resources and, importantly, spur and accelerate scientific discovery. notably, this bill does not take anything away from publishers. no publisher will be forced to publish research under the bill’s provisions; any publisher can simply decline to publish the material if it feels the terms are too onerous. i encourage the library community to contact their representatives to support this bill. open access and open data are the keystones of e-science and its goals of accelerating scientific discovery. i hope that many of you will join me at the lita president’s program on june 24, 2012, in anaheim. tony hey, corporate vice president of microsoft research connections and former director of the u.k.'s e-science initiative, and clifford lynch, executive director of the coalition for networked information, will discuss data-intensive scientific discovery and its implications for libraries, drawing from the seminal work the fourth paradigm. librarians are beginning to explore our role in this new paradigm of providing access to and helping to manage data in addition to bibliographic resources. it is a timely topic and one in which librarians, due to our skill set, are poised to take a leadership role. reading the fourth paradigm was a real game changer for me. it is still extremely relevant. you might consider reading a chapter or two prior to the program. it is an open-access e-book available for download from microsoft research (http://research.microsoft.com/en-us/collaboration/fourthparadigm/). i keep a copy on my ipad, right there with downloaded ital article pdfs.

communication (nfc) an alternative to rfid in libraries neeraj kumar singh information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.11811 neeraj kumar singh (neerajkumar78ster@gmail.com), phd, is deputy librarian, panjab university, chandigarh, india abstract libraries are the central agencies for the dissemination of knowledge. every library aspires to provide maximum opportunities to its users and ensure optimum utilization of available resources. hence, libraries have been seeking technological aids to improve their services. near-field communication (nfc) is a type of radio-frequency technology that allows electronics devices—such as computers, mobile phones, tags, and others—to exchange information wirelessly across a small distance. the aim of this paper is to explore nfc technology and its applications in modern era. the paper will discuss potential use of nfc in the advancement of traditional library management system. introduction similar to other identification technologies such as radio-frequency identification (rfid), barcodes, and qr codes, near-field communication (nfc) is a short-range (4–10 cm) wireless communication technology. nfc is based on the existing 13.56 mhz rfid contactless card standards which have been established for several years and are used for payment, ticketing, electronic passport, and access control among many other applications. data rates range from 106 to 424 kilobits per second. a few nfc devices are already capable of supporting up to 848 kilobits per second which is now being considered for inclusion in the nfc forum specifications. 1 compared to other wireless communication technologies nfc is designed for proximity or shortrange communication which provides a dedicated read zone and some inherent security. its 13.56 mhz frequency places it within the ism band, which is available worldwide. it is a bi-directional communication meaning that you can exchange data in both directions with a typical range of 4 – 10 cm depending on the antenna geometry and the output power.2 nfc is convenient and fast: the action is automatically triggered when your phone comes within 10 cm near the nfc tag and you get instant access to the content on mobile, without a single click.3 rfid and nfc technologies are similar in that both use radio waves. both rfid and nfc technologies exchange data within electronic devices in active mode as well as in passive mode. in the active mode, outgoing signals are basically those that actually come from the power source, whereas in case of passive mode the signals use the reflected energy they have received from the active signal. in rfid technology the radio waves can send information to receivers up to hundreds of meters away depending on the frequency of the band used by th e tag. if provided with high amount of power, these signals can also be sent to extreme distances (e.g., in the case of airport radar). at large airports it typically controls traffic within a radius of 100 kilometers of the airport below an elevation of 25,000 feet. rfid is also used very often in tracking animals and vehicles. mailto:neerajkumar78ster@gmail.com information technology and libraries june 2020 near field communication (nfc) | singh 2 in contrast, items like passports and payment cards should not be capable of long-distance transmissions because of the threat of theft of personal information or funds. nfc is designed to meet this need. nfc tags are very small in size so as to fit on the inner side of devices and products such as inside luggage, purses and packs as well as from inside wallets and clothing and can be tracked. nfc technology has added security features that make it much more secure than the previously popular rfid equivalent and it is difficult to steal information stored in it. nfc has short range of work area compared to other wireless technologies, so it can be widely used for payments, ticketing and service admittance and thus has proved to be a safer technology. it is because of this security feature that this technology is used in cellular phones to turn them into a wallet.4 both rfid and nfc wireless technologies can operate in active and passive communication modes to exchange data within electronic devices. the main differences between nfc and rfid are: • though both rfid and nfc use radio frequencies for communication, nfc can be said to be an extension of the rfid technology. the rfid technology has been in use for more than a decade, but nfc has emerged on the scene recently. • rfid has a wider range whereas nfc has limited communication and operates only at close proximity. nfc typically has a range of a few centimeters. • rfid can function in many frequencies and many standards are being used, but nfc requires a fixed frequency of 13.56 mhz, and some other fixed technical specifications to function properly. • rfid technology can be used for such applications as item tracking, automated toll collecting on roads, vehicle movement, etc., that require wide area signals. nfc is appropriate for applications that carry data that needs to be kept secure like mobile payments, access controls, etc., that carry sensitive information. • rfid operates over long distances while exchanging data wirelessly so it is not secure for the applications that store personalized data. rfid using items susceptible to various fraud attacks such as data corruption. nfc’s short working range considerably reduces this risk of data theft, eavesdropping, and “man in the middle” attacks. • nfc has the capability to communicate both ways and thus is suitable to be used for advanced interactions such as card emulation and peer-to-peer sharing. • a number of rfid tags can be scanned simultaneously, while only a single nfc tag can be scanned at a time. how nfc works the extended functionality of a traditional rfid system has led to the nfc forum. the nfc forum has defined three operating modes for nfc devices: tag reader/writer mode; peer-to-peer mode, and card emulation mode (see figure 1). the nfc forum technical specifications for the different operating modes are based on the iso/iec 18092 nfc ip-1, jis x 6319-4, and iso/iec 14443. these specifications must be used to derive the full benefit from the capabilities of nfc technology. contactless smart card standards are referred to as nfc-a, nfc-b, and nfc-f in nfc forum specifications.5 information technology and libraries june 2020 near field communication (nfc) | singh 3 figure 1. nfc operation modes6 reader/writer mode in reader/writer mode (see figure 2), an nfc-enabled device is capable of reading nfc forummandated tag types, such as a tag embedded in an nfc smart poster. this mode allows nfcenabled devices to read the information that is stored on nfc tags embedded in smart posters and displays. since these tags are relatively inexpensive, they provide a great marketing tool for companies. figure 2. reader mode7 the reader/writer mode on the radio frequency interface is compliant with the nfc-a, nfc-b, and nfc-f schemes. examples of its use include reading timetables, tapping for special offers, and updating frequent flyer points, etc.8 information technology and libraries june 2020 near field communication (nfc) | singh 4 peer-to-peer mode in peer-to-peer mode (see figure 3), both devices must be nfc-enabled in order for them to communicate with each other to exchange information and to share files. the users of nfcenabled devices can thus quickly share information and other files with a touch. as an example, users can exchange data such as digital photos or virtual business cards via bluetooth or wifi. figure 3. peer-to-peer mode9 peer-to-peer mode is based on the nfc forum’s logical link control protocol specification and is standardized on the iso/iec 18092 standard. card-emulation mode in card-emulation mode (see figure 4), an nfc device behaves like a contactless smart card so that users can perform transactions such as purchases, ticketing, and transit access control with just a touch. an nfc device may have the ability to emulate more than one card. in card-emulation mode, an nfc-enabled device communicates with an external reader much like a traditional contactless smart card. this allows contact less payments and ticketing by nfc-enabled devices without changing the existing infrastructure. information technology and libraries june 2020 near field communication (nfc) | singh 5 figure 4. card-emulation mode by adding nfc to a contactless infrastructure one can enable two-way communications. in the air transport sector, this could simplify many operations such as updating seat information while boarding or adding frequent flyer points while making a payment.10 nfc standards and specifications the nfc specifications are defined by an industry organization called the nfc forum, which has nearly 200 member companies. the nfc forum was formed in 2004 with the objective of advancing the use of nfc technology. this was achieved by educating the market about nfc technology and developing specifications to ensure interoperability among devices and services. the nfc forum members are working together in task forces and working groups. as noted earlier, nfc technology is based on existing 13.56 mhz rfid standards and includes several protocols such as iso 14443 type a and type b, and jis x 6319-4 (which is also a japanese industrial standard known as sony felica). the iso 15693 standard, an additional 13.56 mhz protocol established in the market, is being integrated into the nfc specification by an nfc forum task force. smartphones in the market are already supporting the iso 15693 protocol.11 these nfc specifications and especially the specifications for the extended nfc functionalities are again standardized by the international standard organizations like iso/iec ecma and etsi.12 initially the rfid standards i.e. iso/iec 14443 a, iso/iec 14443 b and jis x6319-4 were also pronounced as nfc standards by different companies working in the field such as nxp, infineon, and sony. the first ever nfc standard was ecma 340, based on the air interface of iso/iec 14443a and jis x6319-4. ecma 340 adapted the iso/iec standard 18092. at the same time, major credit card companies like europay, mastercard, and visa introduced the emvco payment standard, which is based on iso/iec 14443 a and iso/iec 14443 b. these groups harmonised the over-the-air interfaces within the nfc forum. they are named nfc-a (iso/iec 14443 a based), nfc-b (iso/iec 14443 b based), and nfc-f (felica based).13 information technology and libraries june 2020 near field communication (nfc) | singh 6 nfc tags an nfc tag is a small microchip embedded in a sticker or wristband that can be read by the mobile devices that are within range. information regarding the item is stored in these microchips.14 an nfc tag has the capability to send the information stored on it to nfc enabled mobile phones. nfc tags can also perform various actions, such as changing the settings of handsets or even launch a website.15 tag memory capacity varies by the type of tag. for example, a tag may store a phone number or a url.16 the most common use of the nfc tag function on an object is mobile wallet payment processing, where the user swipes or flicks a mobile phone on a nfc tag to make payment. google’s version of this system is google wallet.17 figure 5. a quick overview of the tag types18 applications of nfc since it emerged as a standard technology in 2003, nfc technology has been implemented across multiple platforms in various ways. the primary driving force behind nfc is its application in the commercial sector in which the implementation of the technology focuses on such areas as sales and marketing. there are also emerging many new and interesting applications in various other fields of education and healthcare. all of these may impact libraries, librarians, and library users, either by prompting adaptations to existing collections and services or inspiring innovation in our profession.19 • mobile payment: customers with nfc-enabled smartphones can link with their bank accounts and are able to pay by simply tapping phones to an nfc-enabled point-of-sale.20 information technology and libraries june 2020 near field communication (nfc) | singh 7 • access and authentication: “keyless access” to restricted areas, cars, and other vehicles. one can imagine other potential uses of nfc in the future with the devices in the home being controlled by it.21 • transportation and ticketing: nfc-enabled phones can connect with an nfc-enabled kiosk to download a ticket, or the ticket can be sent directly to an nfc-enabled phone over the air (ota). the phone can then tap a reader to redeem that ticket and gain access. 22 • mobile marketing: nfc tags they can be embedded into the indoor and outdoor signage. upon tapping their smartphone on an nfc-enabled smart poster, the customer can read a consumer review, visit a website, or even view a movie trailer. • healthcare: nfc medical cards and bracelet tags can store relevant, up-to-date patient information like health history, allergies, infectious diseases, etc. • gaming: nfc technology is the bridge between physical and digital games. players can tap each other’s phones together and earn extra points or receive access to a new level, or get clues, by using nfc application.23 • inventory tracking, smart packaging, and shelf labels: nfc-tagged objects could provide a wide variety of information in different use environments. nfc-enabled smartphones can be used to tap the tags to access book reviews and information about the book’s author and recommend the book to other readers. users could check out a book or add it to a wish list to check out at a later date. indeed, with nfc, library records and metadata could theoretically be stored on and retrieved from library physical holdings themselves, allowing a patron to tap a book or resource borrowed from the library to recall its title, author, and due date.24 applications of nfc in libraries: introducing the smart library some libraries are beginning to use nfc technology as an alternative to rfid. yusof et al. proposed a newly developed application called the smart library, or “s-library,” that has adopted the nfc technology.25 in the s-library, library users can perform many library transactions just by using their mobile smartphones with integrated nfc technology. the users of s-library are required to download and install an app in their compatible mobile phone. this app provides the user relevant and easy to use library functionality such as searching, borrowing, returning, and viewing their transaction records. in this s-library model the app is integrated with the library management software. the s-library app needs to be installed on the mobile device, and the mobile device requires an internet connection that will connect it to the lms. the s-library provides five major functionalities to the user: scan, search, borrow, return, and transaction history. in the scanning function, users can access the information of a book by simply touching their mobile phone to the nfc tag on the book. as soon as the phone touches the book, information regarding its title, author, contents, synopsis, etc. will automatically be displayed on the screen of the mobile device. users can search for books by entering keywords such as book title, author name, year, etc. through the borrowing function the app allows users to check out books of interest. the user just needs to touch their mobile phone to the nfc-tagged book to borrow it. the transaction is automatically stored to the lms database. similar to the borrowing process is the returning process. the user is required to select the return function on the menu and touch the mobile device to the book, and the returning transaction will be automatically performed and stored in the lms database. however, it should be ensured that the book is physically returned to the library by returning the book through the nfc-enabled book drop information technology and libraries june 2020 near field communication (nfc) | singh 8 system of the library and only then transaction should be updated in the lms. the user can check the due date for the current transaction as well as his transaction history. the function of transaction history allows the user to view the list of books that have been borrowed from time to time and their status.26 data transmission for nfc technology can be up to 848 kilobits/second whereas the data transmission rate with rfid technology is 484 kilobits/second. taking advantage of this high data rate, the response time for s-library is also very fast. this is a huge improvement over rfid technology and especially over barcode technology where data transmission rate is variable and inconsistent and dependent upon the quality of the barcodes. the second key advantage of slibrary is that the time taken to read a tag (the communication time between a reader and an nfc enabled device) is very fast. the third advantage of nfc is its usability in comparison to the other two technologies. nfc technology is human-centric because it is intuitive and fast and the user is able to use it anywhere, anytime using their mobile phones. in rfid and barcode technology usability is item centric as person has to go to the specific device located in the library. 27 most of the shortcomings of rfid and barcode technology have been overcome by the s-library. with barcode technology, the quality of barcodes, printing clarity, print contrast ratio , and also the low level of security were all challenges. rfid technology had many drawbacks such as lack of common rfid standards, security vulnerability, reader and tag collision that happens when multiple tags are energized by the rfid tag reader simultaneously and they reflect their respective signals back to the reader at the same time. because nfc is touch based, it has presented a viable alternative tool for library users to overcome these weaknesses of the older technology. yosof et al. found many advantages to s-library: faster book borrowing; saved time of the user as well as the library staff; the connection can be initialised in less than a second; no configuration on the mobile device is required; and higher usability ratings and security.28 however, there are also some limitations of s-library. first, device compatibility is an issue, because s-library presently supports only the android platform. second, as the s-library application only supports up to a 10centimeter range, coverage is an issue. mobile payments nfc technology can be used for several library functions such as making payments, paying library fines, purchasing tickets to library events, or donating to library. users may also be able to use their digital wallet to pay for photocopying, printing, scanning, etc. keeping the requirements of the nfc technology in the future libraries have to enquire about the possibility of adding nfc payment capabilities into the existing hardware and also while purchasing new machines. already, bibliotheca’s smartserv 1000 self-serve kiosk, introduced in september 2013, includes nfc as a payment option. in the future other library automation companies for nfc integration would also be worth monitoring.29 library access and authentication nfc-enabled devices can be used to accessing the library and authenticate users. these capabilities suggest that nfc technology may play an important role in the next generation of identity management systems. of particular interest in this context are several applications of nfc in two-factor authentication, which generally combines a traditional password or other digital credential with a physical, nfc-enabled component as well. for example, an authentication system information technology and libraries june 2020 near field communication (nfc) | singh 9 could require the user to type in a fixed password in addition to tapping an nfc-enabled phone, identity card, or ring to the device they are logging in to. ibm has demonstrated a two -factor authentication method for mobile payment in which a user first types in a password and then taps an nfc-enabled credit card, issued by their bank, to their nfc-enabled smartphone. libraries could investigate similar access and authentication applications for nfc, both for internal use (staff badges and keys) as well as for public services. particularly if nfc mo bile payment finally gains consumer attraction, library patrons may begin to expect that they can use their nfc-enabled mobile devices to replace not just their credit cards but also their library cards. already, d-tech’s rfid air self check unit allows library patrons to log into their user accounts by tapping their nfc-enabled phone to the kiosk. the patron then uses the kiosk’s rfid reader to check out their library materials and receives a receipt via email or sms. beyond its application in circulation, nfc authentication can be applied to streamline access to other services and resources of the library.30 nfc-enabled devices could be used to make reservation of library spaces, classrooms, auditoriums or community halls, digital media labs, meeting rooms , etc. library users could use nfc authentication to be able to access digital library resources, such as databases, e-journals, e-books collections, and other digital collections. nfc might allow libraries of all kinds to provide more convenient access and authentication options to users, though privacy and security considerations would certainly need to be addressed. nfc access and authentication will certainly have an impact on academic libraries. at universities where nfc access systems are deployed, student identification cards can be replaced with nfc-enabled mobile phones for afterhours services such as library building entry, wifi access, and printing, copying, and scanning services. the inconvenience of multiple logins can be eliminated. however, the libraries will have to take the responsibility of protecting student information and library resources with added security.31 promotion of library services librarians can borrow ideas from commercial implementations of nfc-based marketing to enhance promotions for library resources, services, and events. as a first step, as kane and schneidewind suggested, nfc tags can complement several promotional uses of qr codes that have already been piloted or implemented in libraries. 32 for promotional use, libraries can easily embed nfc tags in their new book displays that can be linked to the bestseller list or current acquisitions lists in the library catalog or digital collections. similarly, if the reference book collection is tagged with nfc tags, it could be linked to the relevant digital collections of databases or e-books. nfc tags can be placed on library building doors or on library promotional material by which information such as library hours, opening days, schedule of events, membership rules , or floor plans for the building could be shared. as an example, at the renison university college library in ontario, canada, visitors can tap an nfc-enabled “library smartcard” to retrieve a digital brochure of library services in a variety of formats, including pdf, epub, and mp3.33 to promote outreach programs and events instead of merely sharing links the libraries can take advantage of nfc’s interactive capabilities. as an example, libraries could use nfc tags on their event posters so that the users that can scan them and register for an event, save the event to their personal calendar, join the friends of the library program, or even download a library app. to send a text message to a librarian the users can tap the smart poster promoting a virtual reference service. nfc-enabled promotional materials can engage users with library content even when they are outside of the library building itself. a brilliantly creative example was created by the field information technology and libraries june 2020 near field communication (nfc) | singh 10 museum of chicago. it used nfc-enabled outdoor smart posters throughout the city to promote an exhibit of the 1893 world’s fair. the event posters depicted a personage from 1893 that invited the viewer to “see what they saw.” users could tap their nfc-enabled mobile device to the smart poster (or read a qr code) to download an app from the field museum that included 360° images of the fair as well as videos highlighting items in the exhibition.34 inventory control the smart packaging use case brings forward a very important question for libraries that use rfid for inventory control. first, can existing rfid tags and infrastructure be leveraged to provide additional services to patrons with nfc-enabled mobile devices? the concept is not new; walsh envisioned using library rfid tags to store book recommendations or other digital information, which users could then access with a conveniently located rfid reader. 35 what nfc brings to walsh’s vision is that a dedicated rfid reader may no longer be necessary; a patron could use their own nfc-enabled smartphone to read a tag rather than taking it to a special location to be read. indeed, with nfc, library records and metadata could theoretically be stored on and retrieved from library physical holdings themselves, allowing a patron to tap a book or resource borrowed from the library to recall its title, author, and due date. an exciting and immediate use for nfc in libraries is for self-checkout: a patron can browse the stacks and could tap an nfctagged book with their nfc-enabled phone to check it out without visiting the circulation desk or waiting in line.36 smart packaging a sector close to librarians’ hearts is publishing and several publishers have started testing smart packaging for books, using embedded nfc tags to share additional content with readers such as book reviews, reading lists, etc. with digital extras, the concept of smart packaging has significant implications for libraries as a new opportunity to connect physical collections (i.e., from books to digital media). one can envision in the future that when a user taps an nfc-enabled library book they shall get access to relevant digital information (such as bibliographic information) in a variety of citation formats, editorial reviews, the author’s biography, a projected rating for the book, and links to other similar information. borrowing and returning books one of a library’s key functions is circulating physical books from the library’s collections. due to the low cost of barcode technology, many libraries around the world are using it for circulation management. however, barcode technology has several constraints: it requires a line-of-sight to the barcode, it does not provide security of library collection, it does not offer any benefit for collection management, and it is becoming challenging for libraries to satisfy the increasing demands of their users, for example, reservation of books issued out, checking their transaction history, etc. this leads to the need to implement a new technology to improve the library circulation management, inventory, and security of library collections. librarians are known as early adopters of technology and have started using rfid to provide circulation services in a more effective and efficient manner, for security of library collections, and to satisfy the increasing demands of the users, for example putting tags in books allows them to issue multiple books together by placing stack of books near a reader. information technology and libraries june 2020 near field communication (nfc) | singh 11 recommendations according to mchugh and yarmey, the implementation of nfc has been slow and unsteady and they do not foresee an immediate implementation in libraries.37 however, they recommend that librarians learn and prepare for nfc. they recommend, for example, that librarians: • follow the progress of research and scholarship on nfc and commercial progress of nfc technology to better anticipate its adoption in your community; • experiment with nfc technology and develop prototype applications for nfc use in the library; • offer an informational workshop on nfc for users and library colleagues; • enquire from the rfid vendor about tag compatibility with nfc and rewriting the tags; • monitor the progress of security and privacy aspects of nfc technology and educate the users about these issues; develop or update your library security policy; • allow patrons to “opt-in” to any nfc services at your library, providing other modes of communication where possible; • develop and share best practices for nfc implementations; and • support research on nfc in libraries via planning grants, research forums, and conference sessions. conclusions beyond the potential benefits of nfc, librarians should also be aware of and prepared for privacy and security concerns that accompany the technology. user privacy is of the utmost concern. nfc involves users’ mobile devices generating, collecting, storing, and sharing a significant amount of personal data. several of these functions, particularly mobile payment, necessitate the exchange of highly confidential data, including but not limited to a user’s financial accounts, purchase history, etc. spam may also be a concern; sending unwanted content (e.g., advertisements, coupons, or adware) to users’ mobile devices without their consent. librarians should also use special caution when considering the implementation of nfc for library promotions or services. security is a significant concern and an active area of research, as many nfc implementations involve the exchange of sensitive financial or otherwise personal data. an important concept in nfc security, particularly in the context of mobile payment, is the idea of a tamper-proof “secure element” as a basic protection for sensitive or confidential data such as account information and credentials for authentication.38 outside of continued standardization, the most effective measures for protecting n fc data transmissions are data encryption and the establishment of a secure channel between the sending and receiving devices (e.g., using a key agreement protocol and/or via ssl). for security concerns, as with privacy concerns, librarians have a crucial role to play in user education. there are important steps that individual users can and should take to protect their devices—e.g., setting a lock code for their device, knowing how to remotely wipe a stolen phone, and installing and regularly updating antivirus software. however, many users are unaware of the vulnerability of their mobile devices and often fail to enact even basic protections. by empowering objects and people to communicate with each other at a different level and establish a “touch to share” paradigm, nfc technology has the potential to transform the information technology and libraries june 2020 near field communication (nfc) | singh 12 information environment surrounding our libraries and fundamentally alter the ways in which the library patrons interact with information. endnotes 1 doaa abdel-gaber and abdel-aleem ali, “near-field communication technology and its impact in smart university and digital library: comprehensive study,” journal

ensured that the public had access to information-related services at their local library. the information the public asked for in 1994, as listed above, is widely available today. there are numerous examples in which librarians and libraries have served as leaders in the ongoing sustainablity of local, regional, and national information networks. it was pointed out at the time, and remains true today, that in an era of ever-shrinking resources, libraries cannot and should not compete with telecommunications, entertainment, and computer companies. they need to “join them as equals in the information arena.”3 lita has a viable role in the development of the twentyfirst-century skills that will firmly put the information infrastructure into place. a lita member is appointed as a liaison to the office for information technology policy (oitp) and serves on the lita technology and access committee, which addresses similar issues. the lita transliteracy interest group explores, develops, and promotes the role of libraries in all aspects of literacy. working with the oitp provides lita membership with the opportunity to participate in current issues, such as digital literacy. the information infrastructure has come a long way in the last twenty some years. there is still much to be done. robert bocher, technology consultant with the wisconsin state library and oitp fellow, will present “building the future: addressing library broadband connectivity issues in the 21st century” at the lita president’s program from 4 p.m. to 5:30 p.m. on sunday, june 26, at the ala annual conference in new orleans. i look forward to seeing you at the program and to hear about the successes and the work that remains to be done to address the broadband needs we all face in the country.

computer waiting queues: alternatives to the first -come-first-served strategy stuart williamson public library computer waiting queues | williamson 72 abstract this paper summarizes the results of a simulation of alternative queuing strategies for a public library computer sign-up system. using computer usage data gathered from a public library, the performance of these various queuing strategies is compared in terms of the distribution of user wait times. the consequences of partitioning a pool of public computers are illustrated as are the potential benefits of prioritizing users in the waiting queue according to the amount of computer time they desire. introduction many of us at public libraries are all too familiar with the scene: a crowd of customers huddled around the library entrance in the morning, anxiously waiting for the doors to open to begin a race for the computers. from this point on, the wait for a computer at some libraries, such as the one we will examine, can hover near thirty minutes on busy days and peak at an hour or more. such long waiting times are a common source of frustration for both customers and staff. by far the most effective solution to this problem is to install more public computers at your library. of course, when the space or money run out, this may no longer be possible. another approach is to reduce the length or number of sessions each customer is allowed. unfortunately, reducing session length can make completion of many important tasks difficult; whereas, restricting the number of sessions per day can result in customers upset over being unable to use idle computers.1 finally, faced with daunting wait times, libraries eager to make their computers accessible to more people may be tempted to partition their waiting queue by installing separate fifteen-minute “express” computers. a primary focus of this paper is to illustrate how partitioning the pool of public computers can significantly increase waiting times. additionally, several alternative queuing strategies are presented for providing express-like computer access without increasing overall waiting times. we often take for granted the notion that first-come-first-served (fcfs) is a basic principle of fairness. “i was here first,” is an intuitive claim that we understand from an early age. however, stuart williamson (swilliamson@metrolibrary.org) is researcher, metropolitan library system, oklahoma city, oklahoma. mailto:swilliamson@metrolibrary.org information technology and libraries | june 2012 73 the inefficiency present in a strictly fcfs queue is implicitly acknowledged when we courteously invite a person with only a few items to bypass our overflowing grocery cart to proceed ahead in the check-out line. most of us would agree to wait an additional few minutes rather than delay someone else for a much greater length of time. when express lanes are present, they formalize this process by essentially allowing customers needing help for only a short period of time to cut in line. these line cuts are masked by the establishment of separate dedicated lines, i.e., the queue is partitioned into express and non-express lines. one question addressed by this article is “is there a middle ground?” in other words, how might a library system set up its computer waiting queue to achieve express-lane type service without splitting the set of public internet computers into partitions that operate separately and in parallel? several such strategies are presented here along with the results of how each performed in a computer simulation using actual customer usage data from a public library. strategies queuing systems are heavily researched in a number of disciplines, particularly computer science and operations research. the complexity and sheer number of different queuing models can present a formidable barrier to library professionals. this is because, in the absence of real-world data, it is often necessary to analyze a queuing system mathematically by approximating its key features with an applicable probability distribution. unfortunately, applying these distributions entails adopting their underlying assumptions as well as any additional assumptions involved in calculating the input parameters. for instance, the poisson distribution (used to approximate customer arrival rates) requires that the expected arrival rate be uniform across all time intervals, an assumption which is clearly violated when school lets out and teenagers suddenly swarm the computers.2 even if we can account for such discrepancies, there remains the difficulty of estimating the correct arrival rate parameter for each discrete time interval being analyzed. fortunately, many libraries now use automated computer sign-up systems which provide access to vast amounts of real-world data. with realistic data, it is possible to simulate various queuing strategies, a few of which will be analyzed in this article. a computer simulation using real-world data provides a good picture of the practical implications of any queuing strategy we care to devise without the need for complex models. as is often the case, designing a waiting queue strategy involves striking a balance among competing factors. for instance, one way of reducing waiting times involves breaking with the fcfs rule and allowing users in one category to cut in front of other users. how many cuts are acceptable? does the shorter wait time for users in one category justify the longer waits in another? there are no right answers to these questions. while simulating a strategy can provide a realistic picture of its results in terms of waiting times, evaluating which strategy’s results are preferable for a particular library must be done on a case-by-case basis. in addition to the standard fcfs strategy with a single pool of computers and the same fcfs strategy implemented with one computer removed from the pool to serve as a dedicated fifteen public library computer waiting queues | williamson 74 minute express computer (referred to as fcfs-15), we will consider for comparison three other well-known alternative queuing strategies: shortest-job-first (sjf), highest-response-ratio-next (hrrn), and a variant of shortest-job-first (sjf-fb) which employs a feedback mechanism to restrict the number of times a given user may be bypassed in the queue.3 the three alternative strategies all require advance knowledge or estimation of how long each particular computer session will last. in our case, this means customers would need to indicate how long of a session they desire upon first signing up for a computer. any number of minutes is acceptable so we will limit the sign-up options to four categories in fifteen-minute intervals: fifteen minutes, thirty minutes, forty-five minutes, and sixty minutes. each session will then be initially categorized into one of four priority classes (p1, p2, p3, and p4) accordingly. as the data will show, customers selecting shorter sessions are given a higher priority in the queue and will thus have a shorter expected waiting time. it should be noted that relying on users to choose their own session length presents its own set of problems. it is often difficult to estimate how much time will be required to accomplish a given set of tasks online. however, users face a similar difficulty in deciding whether to opt for a dedicated fifteen-minute computer under the fcfs-15 system. the trade-off between use time and wait time should provide an incentive for some users to self-ration their computer use, placing an additional downward pressure on wait times. however, user adaptations in response to various queuing strategies are outside the scope of this analysis and will not be considered further. the shortest-job-first (sjf) strategy functions by simply selecting from the queue the user in the highest priority class. the amount of time spent waiting by each user is only considered as a tie breaker among users occupying the same priority class. our results demonstrate that the sjf strategy is generally best for minimizing overall average waiting time as well as for getting customers needing the least amount of computer time online the fastest. the main drawbacks of this strategy are that these gains come at the expense of more line cuts and higher average and maximum waiting times for the lowest priority users—those needing the longest sessions (sixty minutes). there is no limit to how many times a user can be passed over in the queue. in theory, this means that such a user could be continually bypassed and never be assigned a computer during the day. the sjf-fb strategy is a variant of sjf with the addition of a feedback mechanism that increases the priority of users each time they are cut in line. for instance, if a user signs up for a sixtyminute session, he/she is initially assigned a priority of 4. suppose that shortly after, another user signs up for a thirty-minute session and is assigned a priority of 2. the next available computer will be assigned to the user with the priority 2. the bypassed user’s priority will now be bumped up by a set interval. in this simulation an interval of 0.5 is used so the bypassed user’s new priority becomes 3.5. as a result, users beginning with a priority of 4 will reach the highest priority of 1 after being bypassed six times and will not be bypassed further. this effectively restricts the maximum number of times a user can be cut in front of at six. information technology and libraries | june 2012 75 the final alternative strategy, highest-response-ratio-next (hrrn), is a balance between fcfs and sjf. it considers both the arrival time and requested session length when assigning a priority to each user in the queue. each time a user is selected from the queue, the response ratio is recalculated for all users. the user with the highest response ratio is selected and assigned the open computer. the formula for response ratio is: ( ) this allows users with a shorter session request to cut in line, but only up to a point. even customers requesting the longest possible session move up in priority as they wait, just at a slower pace. this method produces the same benefits and drawbacks as the sjf strategy; but the effects of both are moderated, and the possibility of unbounded waiting is eliminated. still, although the expected number of cuts will be lower using hrrn than with sjf, there is no limit on how many times a user may be passed over in the queue. the response ratio formula can be generalized by scaling the importance of the waiting time factor. for instance in the modified response ratio below, increasing values of x > 1 will cause the strategy to more resemble fcfs, and decreasing values of 0 < x < 1 will more resemble sjf. ( ) one could experiment with different values of x to find a desired balance between the number of line cuts and the impact on average waiting times for customers in the various priority classes. this won’t be pursued here, and x will be assumed to be 1. methodology the data used in this simulation come from the metropolitan library system’s southern oaks library in oklahoma city. this library has eighteen public internet computers that customers can sign up for using proprietary software developed by jimmy welch, deputy executive director/technology for the metropolitan library system. the waiting queue employs the firstcome-first-served (fcfs) strategy. customers are allotted an initial session of up to sixty minutes but may extend their session in thirty-minute increments so long as the waiting queue is empty. repeat customers are also allowed to sign up for additional thirty-minute sessions during the day, provided that no user currently in the queue has been waiting for more than ten minutes (an indication that demand for computers is currently high). anonymous usage data gathered by the system in august 2010 was compiled to produce the information about each customer session shown in table 1. public library computer waiting queues | williamson 76 table 1. session data (units in minutes) the information about each session required for the simulation includes the time at which the user arrived to sign up for a computer, the number of minutes it took the user to log in once assigned a computer, how many minutes of computer time were used, whether or not this was the user’s first or a subsequent session for the day, and finally, whether the user gave up waiting and abandoned his/her place in the queue. users are given eight minutes to log in once a computer station is assigned to them before they are considered to have abandoned the queue. once this data has been gathered, the computer simulation runs by iterating through each second the library is open. as user sign-up times are encountered in the data, they are added to the waiting queue. when a computer becomes available, a user is selected from the queue using the strategy being simulated and assigned to the open computer. the customer occupies the computer for the length of time given by their associated log-in delay and session length. when this time expires, customers are removed from their computer and the information recorded during their time spent in the waiting queue is logged. results there were 7,403 sign-ups for the computers at the southern oaks library in august 2010. each of these requests is assigned a priority class based on the length of the session as detailed in table 2. the intended session length of users choosing to abandon the queue is unknown. abandoned sign-ups are assigned a priority class randomly in proportion to the overall distribution of priority classes in the data so as not to introduce any systematic bias into the results. even though their actual session length is zero, these users participate in the queue and cause the computer eventually assigned to them to sit idle for eight minutes until it is re-assigned. customers signing up for a subsequent session during the day are always assigned the lowest priority class (p-4) regardless of their requested session length. this is a policy decision to not give priority to users who have already received a computer session for the day. information technology and libraries | june 2012 77 table 2. assignment of priority classes figure 1 displays the average waiting time for each priority class during the simulation (bars) along with the total number of sessions initially assigned to each class (line). it is immediately obvious from the chart that each alternative strategy excels at reducing the average wait for high priority (p1) users. also observe how removing one computer from the pool to serve exclusively as a fifteen-minute computer drastically increases the fcfs-15 average wait times in the other priority classes. clearly, removing one (or more) computer from the pool to serve as a dedicated fifteen-minute station is a poor strategy here for all but the 519 users in class p-1. losing just one of the eighteen available computers nearly doubles the average wait for the remaining 6,884 users in the other priority classes. figure 1. average user wait minutes by priority class public library computer waiting queues | williamson 78 by contrast, note that the reduced average wait times for the highest priority users in class p-1 persist in classes p-2 and p-3 for the non-fcsc strategies. the sjf strategy produces the most dramatic reductions for the 2,164 users not in class p-4. however, for the 5,239 users in class p-4, the sjf strategy produced an average wait time that was 2.1 minutes longer than the purely fcfs strategy. the hrrn strategy achieves lesser wait time reductions than sjf in the higher priority classes, but hrrn increased the average wait for users in class p-4 by only 0.7 minutes relative to fcfs. the average wait using the sjf-fb strategy falls in between that of sjf and hrrn for each priority class while guaranteeing users will be cut at most six times. an examination of the maximum wait times for each priority class in figure 2 illustrates how the express lane itself can be a bottleneck. even with a dedicated fifteen-minute express computer under the fcfs-15 strategy, at least one user would have waited over half an hour to use a computer for fifteen minutes or less. in all but the highest priority class (p-2 through p-4), the fcfs-15 strategy again performs poorly with at least one user in each of these classes waiting over ninety minutes for a computer. figure 2. maximum user wait minutes by priority class capping the number of times a user may be passed over in the queue under the sfj-fb strategy makes it less likely that members of classes p-2 and p-3 will be able to take advantage of their higher priority to cut in front of users in class p-4 during periods of peak demand. as a result, the sjf-fb maximum wait times for classes p-2 and p-3 are similar to those under the fcfs strategy. this was not the case in the breakdown of sjf-fb average waiting times across priority classes in figure 1. information technology and libraries | june 2012 79 table 3 breaks down waiting times for each queuing strategy according to the overall percentage of users waiting no more than the given number of minutes. here we see the effects of each strategy on the system as a whole, instead of by priority class. notice that the overall average wait times for the non-fcfs strategies are lower than those of fcfs. this indicates that the total reduction in waiting times for high-priority users exceeds the additional time spent waiting by users in class p-4. in other words, these strategies are globally more efficient than fcfs. notice, too, in table 3 that the non-fcfs strategies achieve significant reductions in the median wait time compared with fcfs. table 3. distribution of wait times by strategy after demonstrating the impact that breaking the first-come-first-served rule can have on waiting times, it is important to examine the line cuts that are associated with each of these strategies. line cuts are recorded by each user in the simulation while waiting in the queue. each time a user is selected from the queue and assigned a computer, remaining users who arrived prior to the one just selected note having been skipped over. by the time they are assigned a computer, users have recorded the total number of times they were passed over in the queue. public library computer waiting queues | williamson 80 figure 3. cumulative distribution of line cuts by queuing strategy figure 3 displays the cumulative percentage of users experiencing no more than the listed number of cuts for each non-fcfs strategy. the majority of users are not passed over at all under these strategies. however, there is a small minority of users that will be repeatedly cut in line. for instance, in our simulation, one unfortunate individual was passed over in the queue sixteen times under the sjf strategy. this user waited ninety-one minutes using this strategy as opposed to only fifty-nine minutes under the familiar fcfs waiting queue. most customers would become upset upon seeing a string of sixteen people jump over them in the queue and get on a computer while they are enduring such a long wait. the hrrn strategy caused a maximum of nine cuts to an individual in this simulation. this user waited seventy-three minutes under hrrn versus only fifty-five minutes using fcfs. extreme examples such as those above are the exception. under the hrrn and sjf-fb strategies, 99% of users were passed over at most four times while waiting in the queue. conclusion we have examined the simulation of several queuing strategies using a single month of computer usage data from the southern oaks library. the relative performance difference between queuing strategies will depend on the supply and demand of computers at any given location. clearly, at libraries with plenty of public computers for which customers seldom have to wait, the choice of queuing strategy is inconsequential. however, for libraries struggling with waiting times on par with those examined here, the choice can have a substantial impact. information technology and libraries | june 2012 81 in general, however, these simulation results demonstrate the ability of non-fcfs queuing strategies to significantly lower waiting times for certain classes of users without partitioning the pool of computers. these reductions in waiting times come at the cost of allowing high priority users to essentially cut in line. this causes slightly longer wait times for low priority users; but, overall average and median wait times see a small reduction. of course, for some customers, being passed over in line even once is intolerable. furthermore, creating a system to implement an alternative queuing strategy may present obstacles of its own. however, if the need to provide for quick, short-term computer access is pressing enough for a library to create a separate pool of “express” computers; then, one of the non-fcfs queuing strategies discussed in this paper may be a viable alternative. at the very least, the fcfs-15 simulation results should give one pause before resorting to designated “express” and “nonexpress” computers in an attempt to remedy unacceptable customer waiting times. acknowledgments the author would like to thank the metropolitan library system, kay bauman, jimmy welch, sudarshan dhall, and bo kinney for their support

classification using wikipedia | yelton 7 andromeda yelton a simple scheme for book classification using wikipedia ■■ background hanne albrechtsen outlines three types of strategies for subject analysis: simplistic, content-oriented, and requirements-oriented.3 in the simplistic approach, “subjects [are] absolute objective entities that can be derived as direct linguistic abstractions of documents.” the content-oriented model includes an interpretive step, identifying subjects not explicitly stated in the document. requirementsoriented approaches look at documents as instruments of communication; thus they anticipate users’ potential information needs and consider the meanings that documents may derive from their context. (see, for instance, the work of hjørland and mai.4) albrechtsen posits that only the simplistic model, which has obvious weaknesses, is amenable to automated analysis. the difficulty in moving beyond a simplistic approach, then, lies in the ability to capture things not stated, or at least not stated in proportion to their importance. synonymy and polysemy complicate the task. background knowledge is needed to draw inferences from text to larger meaning. these would be insuperable barriers if computers limited to simple word counts. however, thesauri, ontologies, and related tools can help computers as well as humans in addressing these problems; indeed, a great deal of research has been done in this area. for instance, enriching metadata with princeton university’s wordnet and the national library of medicine’s medical subject headings (mesh) is a common tactic,5 and the yahoo! category structure has been used as an ontology for automated document classification.6 several projects have used library of congress classification (lcc), dewey decimal classification (ddc), and similar library tools for automated text classification, but their results have not been thoroughly reported.7 all of these tools have had problems, though, with issues such as coverage, currency, and cost. this has motivated research into the use of wikipedia in their stead. since wikipedia’s founding in 2001, it has grown prodigiously, encompassing more than 3 million articles in its english edition alone as of this writing; this gives it unparalleled coverage. wikipedia also has many thesaurus-like features. redirects function as “see” references by linking synonyms to preferred terms. disambiguation pages deal with homonyms. the polyhierarchical category structure provides broader and narrower term relationships; the vast majority of pages belong to at least one category. links between pages function as related-term indicators. editor’s note: this article is the winner of the lita/ex libris student writing award, 2010. because the rate at which documents are being generated outstrips librarians’ ability to catalog them, an accurate, automated scheme of subject classification is desirable. however, simplistic word-counting schemes miss many important concepts; librarians must enrich algorithms with background knowledge to escape basic problems such as polysemy and synonymy. i have developed a script that uses wikipedia as context for analyzing the subjects of nonfiction books. though a simple method built quickly from freely available parts, it is partially successful, suggesting the promise of such an approach for future research. a s the amount of information in the world increases at an ever-more-astonishing rate, it becomes both more important to be able to sort out desirable information and more egregiously daunting to manually catalog every document. it is impossible even to keep up with all the documents in a bounded scope, such as academic journals; there were more than twenty-thousand peer-reviewed academic journals in publication in 2003.1 therefore a scheme of reliable, automated subject classification would be of great benefit. however, there are many barriers to such a scheme. naive word-counting schemes isolate common words, but not necessarily important ones. worse, the words for the most important concepts of a text may never occur in the text. how can this problem be addressed? first, the most characteristic (not necessarily the most common) words in a text need to be identified—words that particularly distinguish it from other texts. some corpus that connects words to ideas is required—in essence, a way to automatically look up ideas likely to be associated with some particular set of words. fortunately, there is such a corpus: wikipedia. what, after all, is a wikipedia article, but an idea (its title) followed by a set of words (the article text) that characterize that title? furthermore, the other elements of my scheme were readily available. for many books, amazon lists statistically improbable phrases (sips)— that is, phrases that are found “a large number of times in a particular book relative to all search inside! books.”2 and google provides a way to find pages highly relevant to a given phrase. if i used google to query wikipedia for a book’s sips (using the query form “site:en.wikipedia .org sip”), would wikipedia’s page titles tell me something useful about the subject(s) of the book? andromeda yelton (andromeda.yelton@gmail.com) graduated from the graduate school of library and information science, simmons college, boston, in may 2010. 8 information technology and libraries | march 2011 ■■ an initial test case to explore whether my method was feasible, i needed to try it on a test case. i chose stephen hawking’s a brief history of time, a relatively accessible meditation on the origin and fate of the universe, classified under “cosmology” by the library of congress. i began by looking up its sips on amazon.com. noticing that amazon also lists capitalized phrases (caps)—“people, places, events, or important topics mentioned frequently in a book”—i included those as well (see table 1).14 i then queried wikipedia via google for each of these phrases, using queries such as “site:en.wikipedia .org ‘grand unification theory.’” i selected the top three wikipedia article hits for each phrase. this yielded a list of sixty-one distinct items with several interesting properties: ■■ four items appeared twice (arrow of time, entropy [arrow of time], inflation [cosmology], richard feynman). however, nothing appeared more than twice; that is, nothing definitively stood out. ■■ many items on the list were clearly relevant to brief history, although often at too small a level of granularity to be good subject headings (e.g., black hole, second law of thermodynamics, time in physics). ■■ some items, while not unrelated, were wrong as subject classifications (e.g., list of solar system objects by size, nobel prize in physics). ■■ some items were at best amusingly, and at worst bafflingly, unrelated (e.g., alpha centauri [doctor who], electoral district [canada], james k. polk, united states men’s national soccer team). ■■ in addition, i had to discard some of the top google hits because they were not articles but wikipedia special pages, such as “talk” pages devoted to discussion of an article. this test showed that i needed an approach that would give me candidate subject headers at a higher level of granularity. i also needed to be able to draw a brighter line between candidates and noncandidates. the presence of noncandidates was not in itself distressing—any automated approach will consider avenues a human would not—but not having a clear basis for discarding low-probability descriptors was a problem. as it happens, wikipedia itself offers candidate subject headers at a higher level of granularity via its categories system. most articles belong to one or more categories, which are groups of pages belonging to the same list or topic.15 i hoped that by harvesting categories from the sixty-one pages i had discovered, i could improve my method. this yielded a list of more than three hundred categories. unsurprisingly, this list mostly comprised irrelevant because of this thesaurus structure, all of which can be harvested and used automatically, many researchers have used wikipedia for metadata enrichment, text clustering and classification, and the like. for example, han and zhao wanted to automatically disambiguate names found online but faced many problems familiar to librarians: “the traditional methods measure the similarity using the bag of words (bow) model. the bow, however, ignores all the semantic relations such as social relatedness between named entities, associative relatedness between concepts, polysemy and synonymy between key terms. so the bow cannot reflect the actual similarity.” to counter this, they constructed a semantic model from information on wikipedia about the associative relationships of various ideas. they then used this model to find relationships between information found in the context of the target name in different pages. this enabled them to accurately group pages pertaining to particular individuals.8 carmel, roitman, and zwerdling used page categories and titles to enhance labeling of document clusters. although many algorithms exist for sorting large sets of documents into smaller, interrelated clusters, there is less work on labeling those clusters usefully. by extracting cluster keywords, using them to query wikipedia, and algorithmically analyzing the results, they created a system whose top five recommendations contained the human-generated cluster label more than 85 percent of the time.9 schönhofen looked at the same problem i examine— identifying document topics with wikipedia data—but he used a different approach. he calculated the relatedness between categories and words from titles of pages belonging to those categories. he then used that relatedness to determine how strongly words from a target document predicted various wikipedia categories. he found that although his results were skewed by how wellrepresented topics were on wikipedia, “for 86 percent of articles, the top 20 ranked categories contain at least one of the original ones, with the top ranked category correct for 48 percent of articles.”10 wikipedia has also been used as an ontology to improve clustering of documents in a corpus,11 to automatically generate domain-specific thesauri,12 and to improve wikipedia itself by suggesting appropriate categories for articles.13 in short, wikipedia has many uses for metadata enrichment. while text classification is one of these potential uses, and one with promise, it is under-explored at present. additionally, this exploration takes place almost entirely in the proceedings of computer science conferences, often without reference to library science concepts or in a place where librarians would be likely to benefit from it. this paper aims to bridge that gap. a simple scheme for book classification using wikipedia | yelton 9 computationally trivial to do so, given such a list. (the list need not be exhaustive as long as it exhaustively described category types; for instance, the same regular expression could filter out both “articles with unsourced statements from october 2009” and “articles with unsourced statements from may 2008.”) at this stage of research, however, i simply ignored these categories in analyzing my results. to find a variety of books to test, i used older new york times nonfiction bestseller lists because brand-new books are less likely to have sips available on amazon.19 these lists were heavily slanted toward autobiography, but also included history, politics, and social science topics. ■■ results of the thirty books i examined (the top fifteen each from paperback and hardback nonfiction lists), twenty-one had sips and caps available on amazon. i ran my script against each of these phrase sets and calculated three measures for each resulting category list: ■■ precision (p): of the top categories, how many were synonyms or near-synonyms of the book’s lcshs? ■■ recall (r): of the book’s lcshs, how many had synonyms or near-synonyms among the top categories? ■■ right-but-wrongs (rbw): of the top categories, how many are reminiscent of the lcshs without actually being synonymous? these included narrower terms (e.g., the category “african_american_actors” when the lcshs included “actors—united states —biography”), broader terms (e.g., “american_folk_ singers” vs. “dylan, bob, 1941–”), related terms (e.g., “the_chronicles_of_narnia_books” vs. “lion, the witch and the wardrobe (motion picture)”), and examples (“killian_documents_controversy” vs. “united states—politics and government—2001–2009”). i considered the “top categories” for each book to be the five that most commonly occurred (excluding wikipedia administrative categories), with the following exceptions: ■■ because i had no basis to distinguish between them, i included all equally popular categories, even if that would bring the total to more than five. thus, for example, for the book collapse, the most common category occurred seven times, followed by two categories with five appearances and six categories with four. rather than arbitrarily selecting two of the six four-occurrence categories to bring the total to five, i examined all nine top categories. ■■ if there were more than five lcshs, i expanded the number of categories accordingly, so as not to candidates (“wars involving the states and peoples of asia,” “video games with expansion packs,” “organizations based in sweden,” among many others). many categories played a clear role in the wikipedia ecology of knowledge but were not suitable as general-purpose subject headers (“living people,” “1849 deaths”). strikingly, though, the vast majority of candidates occurred only once. only forty-two occurred twice, fifteen occurred three times, and one occurred twelve times: “physical cosmology.” twelve occurrences, four times as many as the next candidate, looked like a bright line. and “physical cosmology” is an excellent description of brief history— arguably better than lcsh’s “cosmology.” the approach looked promising. ■■ automating further test cases the next step was to test an extensive variety of books to see if the method was more broadly applicable. however, running searches and collating queries for even one book is tedious; investigating a large number by hand was prohibitive. therefore i wrote a categorization script (see appendix) that performs the following steps:16 ■■ reads in a file of statistically improbable phrases17 ■■ runs google queries against wikipedia for all of them18 ■■ selects the top hits after filtering out some common wikipedia nonarticles, such as “category” and “user” pages ■■ harvests these articles’ categories ■■ sorts these categories by their frequency of occurrence this algorithm did not filter out wikipedia administrative categories, as creating a list of them would have been prohibitively time-consuming. however, it would be table 1. sips and caps for a brief history of time sips grand unification energy, complete unified theory, thermodynamic arrow, psychological arrow, primordial black holes, boundary proposal, hot big bang model, big bang singularity, more quarks, contracting phase, sum over histories caps alpha centauri, solar system, nobel prize, north pole, united states, edwin hubble, royal society, richard feynman, milky way, roger penrose, first world war, weak anthropic principle 10 information technology and libraries | march 2011 “continental_army_generals” vs. “united states— history—revolution, 1775–1783.” ■■ weak: some categories treated the same subject as the lcsh but not at all in the same way ■■ wrong: the categories were actively misleading the results are displayed in table 2. ■■ discussion the results of this test were decidedly more mixed than those of my initial test case. on some books the wikipedia method performed remarkably well; on misleadingly increase recall statistics. ■■ i did not consider any categories with fewer than four occurrences, even if that left me with fewer than five top categories to consider. the lists of three-, two-, and one-occurrence categories were very long and almost entirely composed of unrelated items. i also considered, subjectively, the degree of overlap between the lcshs and the top wikipedia categories. i chose four degrees of overlap: ■■ strong: the top categories were largely relevant and included synonyms or near-synonyms for the lcsh ■■ near miss: some categories suggested the lcsh but missed its key points, such as table 2. results (sorted by percentage of relevant categories). book p r rbw subjective quality chronicles, bob dylan 0.2 0.5 0.8 strong the chronicles of narnia: the lion, the witch and the wardrobe official illustrated movie companion, perry moore 0.25 1 0.625 strong 1776, david mccullough 0 0 0.8 near miss 100 people who are screwing up america, bernard goldberg 0 0 0.625 weak the bob dylan scrapbook, 1956–1966, with text by robert santelli 0.2 0.5 0.4 strong three weeks with my brother, nicholas sparks 0 0 0.57 weak mother angelica, raymond arroyo 0.07 0.33 0.43 near miss confessions of a video vixen, karrine steffans 0.25 0.33 0.25 weak the fairtax book, neal boortz and john linder 0.17 0.33 0.33 strong never have your dog stuffed, alan alda 0 0 0.43 weak the world is flat, thomas l. friedman 0.4 0.5 0 near miss the tender bar, j. r. moehringer 0 0 0.2 wrong the tipping point, malcolm gladwell 0 0 0.2 wrong collapse, jared diamond 0 0 0.11 weak blink, malcolm gladwell 0 0 0 wrong freakonomics, steven d. levitt and stephen j. dubner 0 0 0 wrong guns, germs, and steel, jared diamond 0 0 0 weak magical thinking, augusten burroughs 0 0 0 wrong a million little pieces, james frey 0 0 0 wrong worth more dead, ann rule 0 0 0 wrong tuesdays with morrie, mitch albom no category with more than 4 occurrences a simple scheme for book classification using wikipedia | yelton 11 my method’s success with a brief history of time. i tested another technical, jargon-intensive work (n. gregory mankiw’s macroeconomics textbook), and found that the method also worked very well, giving categories such as “macroeconomics” and “economics terminology” with high frequency. therefore a system of this nature, even if not usable for a broad-based collection, might be very useful for scientific or other jargon-intensive content such as a database of journal articles. ■■ future research the method outlined in this paper is intended to be a proof of concept using readily available tools. the following work might move it closer to a real-world application: ■■ a configurable system for providing statistically improbable phrases; there are many options.23 this would provide the user with more control over, and understanding of, sip generation (instead of the amazon black box), as well as providing output that could integrate directly with the script. ■■ a richer understanding of the wikipedia category system. some categories (e.g., “all articles with unsourced statements”) are clearly useful only for wikipedia administrative purposes, not as document descriptors; others (e.g., “physical cosmology”) are excellent subject candidates; others have unclear value as subjects or require some modification (e.g., “environmental non-fiction books,” “macroeconomics stubs”). many of these could be filtered out or reformatted automatically. ■■ greater use of wikipedia as an ontology. for example, a map of the category hierarchies might help locate headers at a useful level of granularity, or to find the overarching meaning suggested by several headers by finding their common broader terms. a more thorough understanding of wikipedia’s relational structure might help disambiguate terms.24 others, it performed very poorly. however, there are several patterns here: many of these books were autobiographies, and the method was ineffective on nearly all of these.20 a key feature of autobiographies, of course, is that they are typically written in the first person, and thus lack any term for the major subject—the author’s name. biography, by contrast, is rife with this term. this suggests that including titles and authors along with sips and caps may be wise. additionally, it might require making better use of wikipedia as an ontology to look for related concepts (rather in the manner that han and zhao used it for name disambiguation).21 books that treat a single, well-defined subject are easier to analyze than those with more sprawling coverage. in particular, books that treat a concept via a sequence of illustrative essays (e.g., tipping point, freakonomics) do not work well at all. sips may apply only to particular chapters rather than to the book as a whole, and the algorithm tends to pick out topics of particular chapters (e.g., for freakonomics, the fascinating chapter on sudhir venkatesh’s work on “gangs_in_chicago, _illinois”22) rather than the connecting threads of the entire book (e.g. “economics—sociological aspects”). the tactics suggested for autobiography might help here as well. my subjective impressions were usually, but not always, borne out by the statistics. this is because some of the rbws were strongly related to one another and suggested to a human observer a coherent narrative, whereas others picked out minor or dissimilar aspects of the book. there was one more interesting, and promising, pattern: my subjective impressions of the quality of the categories were strongly predicted by the frequency of the most common category. remember that in the brief history example, the most common category, “physical cosmology,” occurred twelve times, conspicuously more than any of its other categories. therefore i looked at how many times the top category for each book occurred in my results. i averaged this number for each subjective quality group; the results are in table 3. in other words, the easier it was to draw a bright line between common and uncommon categories, the more likely the results were to be good descriptions of the work. this suggests that a system such as this could be used with very little modification to streamline categorization. for example, it could automatically categorize works when it met a high confidence threshold (when, for instance, the most common category has double-digit occurrence), suggest categories for a human to accept or reject at moderate confidence, and decline to help at low confidence. it was also interesting to me that—unlike my initial test case—none of the bestsellers were scientific or technical works. it is possible that the jargon-intensive nature of science makes it easier to categorize accurately, hence table 3. category frequency and subjective quality subjective quality of categories frequencies of most common category average frequency of most common category strong 6, 12, 16, 19 13.25 near miss 5, 5, 7, 10 6.75 weak 4, 5, 6, 7, 8 6 wrong 3, 4, 4, 5, 5, 5, 7, 7 5 12 information technology and libraries | march 2011 (1993): 219. 4. birger hjørland, “the concept of subject in information science,” journal of documentation 48, no. 2 (1992): 172;

opac | mi and weng 5 the behavior of academic library users has drastically changed in recent years. internet search engines have become the preferred tool over the library online public access catalog (opac) for finding information. libraries are losing ground to online search engines. in this paper, two aspects of opac use are studied: (1) the current opac interface and searching capabilities, and (2) the opac bibliographic display. the purpose of the study is to find answers to the following questions: why is the current opac ineffective? what can libraries and librarians do to deliver an opac that is as good as search engines to better serve our users? revitalizing the library opac is one of the pressing issues that has to be accomplished. t he information-seeking behavior of today’s academic library users has drastically changed in recent years. according to a survey conducted and published by oclc in 2005, approximately 89 percent of college students across all the regions that were included in the study (including areas outside the united states) begin their electronic information searches with internet search engines.1 more than half of u.s. residents used google for their searches. internet search engines dominate the information-seeking landscape. academic libraries are the ones affected most, because many college students are satisfied with the answers they find on the internet for their assignments, and they end up not taking advantage of the many quality resources in their libraries. for many years, before the internet search engine emerged, library catalogs were the sole information-seeking gateway. just as the one-time industry giant kodak has lost ground to digital photography, academic library opacs are losing ground to online search engines. all along we academic librarians have devotedly and assiduously produced good cataloging records for the public to use. we have diligently and faithfully educated and helped our faculty and students find the proper library resources to fulfill their research needs and assignment requirements. we feel good about what we have achieved. why have our users switched to online search engines? ■ the evolution of user behavior it is technology and rising user expectations that have contributed to the changes in user behavior. as coyle and hillmann pointed out: “today’s library users have a different set of information skills from those of just a few decades ago. they live in a highly interactive, networked world and routinely turn to web search engines for their information needs.”2 a recent study conducted by the university of georgia on undergraduate research behavior in using the university’s electronic library concluded that internet sites and online instruction modules are the primary sources for their research.3 the students’ year of study did not make much of a difference in their choices. tenopir also concluded from her study of approximately 200 scholarly works published between 1995 and 2003 that no matter what type of resources were used, “convenience remains the single most important factor for information use.”4 recently, oclc identified three major trends in the needs of today’s information consumers—self-service (moving to self-sufficiency), satisfaction, and seamlessness.5 services provided by google, amazon, and similar companies are the major cause of these emerging trends. customers have wholeheartedly embraced these products because of their ease of use and quick delivery of “good enough” results. researchers do not need to take information literacy classes to learn how to use an online search engine. they do not need to worry about forgetting important but infrequently used search rules or commands. in addition, the search results delivered by online search engines are sorted using relevance ranking systems that are more user-friendly than the ones currently employed by academic library opacs. these are just some of the features that current academic library opacs fail to deliver. in 2004, campbell and fast presented their analysis of an exploratory study of university students’ perceptions of searching opacs and web search engines.6 they found that “[s]tudents express a distinct preference for search engines over library catalogues, finding the catalogue baffling and difficult to use effectively.” as a result, library opacs, because they do not fulfill user needs, have been bombarded with criticism.7 we often hear librarians complain about how library users forget what they have learned in user education classes. librarians sometimes even laugh at users’ ignorance and ineffectiveness in searching library opacs. this legacy mentality has actually prevented librarians from recognizing the changes in user behavior and expectations that have occurred in the past decade. rarely have librarians considered ineffective opac design to be at the root of unsuccessful opac use. roy tennant has mentioned frequently in his presentations that “only librarians like to search; users prefer to find”; that “users aren’t lazy, they are jia mi and cathy weng revitalizing the library opac: interface, searching, and display challenges jia mi (jmi@tcnj.edu) is electronic resources/serials librarian and cathy weng (weng@tcnj.edu) is head of cataloging, the college of new jersey library, ewing. 6 information technology and libraries | march 20086 information technology and libraries | march 2008 human.”8 it is only natural that library users turn to internet search engines first for their information needs. ■ the opac reexamined cutter, in his 1876 book, introduced the objectives of the library catalog as follows: 1. to enable a person to find a book of which either a. the author b. the title is known c. the subject 2. to show what the library has a. by a given author b. on a given subject c. in a given kind of literature 3. to assist in the choice of a book a. as to its edition (bibliographically) b. as to its character (literary or topical)9 the majority of today’s opacs have successfully fulfilled cutter’s model in finding known items. following the card-catalog convention, bibliographic elements such as title, author, and subject have been the leading search options in opac search menus for many years. it was assumed that users always came to the library with specific author, title, or subject information in mind before searching the catalog. the opac bibliographic display is in essence an electronic version of the card catalog. to accommodate the bibliographic data from card catalogs, many display labels were created, but often without regard to whether or not they were suitable in an online environment. this data-centered, card-catalog type of design was easily understood and fluently used by librarians, but not by most end users. campbell and fast found in their study that “while the participants were generally happy with their understanding of search engines, they frequently expressed a low opinion of their ability to search the catalogue.” they also found that students felt that “[t]he web is cluttered; the catalogue is organized. however, this organization was not always helpful; it was admired, but not understood.”10 the traditional catalog retrieval mechanism is significantly different from the web search engine. as yu and young noted in 2004, “web search engines and online bookstores have a number of features that are not typically incorporated into opacs. these functions include: natural-language entry, automated mapping to controlled vocabulary, spell-checking, similar pages, relevance-ranked output, popularity tracking, and browsing.”11 these features have unquestionably affected user expectations in searching library opacs. teaching users to search for structured bibliographic data is completely opposed to the ever-popular free and open internet search mechanism drawn from the google-like search experience, which does not require any special training. since academic libraries aim to provide more dynamic and versatile services, revitalizing library opacs should be considered a top priority. furthermore, librarians’ expectations of user behavior should adjust to today’s needs. educating users to become fluent in using opac search commands and rules has become less relevant as users now seldom read and follow instructions. investing effort and energy in designing a truly user-friendly opac that functions intuitively to achieve productive retrieval could not be more imperative. academic librarians have started pondering what changes should be made to library opacs so that a truly user-friendly, twenty-first-century catalog that offers a “google-like” experience can be delivered. two important aspects that affect the usability of library opacs are addressed in this article: (1) the current interface and searching capabilities and (2) the bibliographic display. the opac’s public interface and searching capabilities together function as a finding aid. it determines how successful a user is in retrieving information and is the gateway to library resources. the effectiveness of an opac’s bibliographic display affects the user’s understanding of the bibliographic description. users use bibliographic information to identify, select, and obtain library resources. ■ the study of the public interface of library opacs to find out how academic libraries designed and administered their opacs, the authors examined the interfaces of 123 association of research libraries (arl) libraries’ opacs powered by five major integrated library systems (ils): aleph, horizon, millennium, unicorn, and voyager. the study focused on searching ability, relevance ranking, layout, and linking functionalities. during the study, we expected each ils system to have its own opac design. we also anticipated that search mechanisms would be managed differently at each location. however, we were surprised by the great disparities that we discovered in opac quality, a clear indication of the time and effort (or lack thereof) devoted to their maintenance and improvement. the findings are summarized below. google-driven changes—keyword search as the default search key in his article “mental models for search are getting firmer,” usability expert jakob nielsen argued that cur> article title | author 7revitalizing the library opac | mi and weng 7 rent users have already developed a firm mental model of searching: search is such a prominent part of the web user experience that users have developed a firm mental model for how it’s supposed to work. users expect search to have three components: ■ a box where they can type words ■ a button labeled “search” that they click to run the search ■ a list of top results that’s linear, prioritized, and appears on a new page—the search engine results page (serp) in our experience, when users see a fat “search” button, they’re likely to frantically look for “the box where i type my words.” the mental model is so strong that the label “search” equals keyword searching, not other types of search.12 studies have also shown that the default search option to which an opac is set affects users’ success in retrieving information. two studies on university opac search transactions confirmed that novice users preferred searching by keyword. at nanyang technological university, singapore, a recent search transaction log study was conducted to “identify query and search failure patterns with the goal of identifying areas of improvement for the system.” results indicated that “the most commonly used search option for the ntu opac is the keyword search. the use of keyword searches contributed to 68.9 percent of all queries while other options such as title, author, and subject accounted for 16.5 percent, 8.2 percent, and 6.4 percent of all searches respectively.”13 at california state university–los angeles, a fourquarter (2002–2003) search transaction log analysis also revealed similar results. after the library implemented an “advanced keyword search” feature that provided more user-centered, behind-the-scenes search algorithms and that set keyword search as the default, the keyword search queries rose dramatically.14 many university library opacs have already begun to adopt features employed by internet search engines. among the 123 arl library opacs studied, 81 have “keyword(s) anywhere” as the default search key (see appendix a). this is a positive sign that libraries are paying attention to user search behavior. thirty-six libraries’ default search keys are still set to “title,” and six libraries, instead of providing a default search option, list field choices from which users must choose before entering their search terms. the title search used as the default option holds some potential problems. in order to retrieve good results from a title search, users are expected to type in a title in the right order, spelled correctly, and omitting the initial article (a, an, the), if any. while librarians are fluent with these seemingly simple rules, students and faculty constantly have trouble remembering them. providing online search tips and offering information literacy classes only help a little. since presenting keyword search as the default has proved effective, libraries using title search as their opac default search option might want to reconsider switching their default setting to keyword. search ability—true keyword search the basis of current opac search systems is boolean logic. the ease of using google-like search engines comes from its implicit “and” feature, which eliminates the need to enter boolean connectors (and, or, not) between search terms. this is logical because users usually look for records that contain all the terms that they enter. sixty-six percent of the arl libraries studied have opacs with keyword set as the default search option. these libraries handle boolean logic in keyword searching very differently. all five ils vendors offer “automatic and” functionality, but not all of these libraries have adopted it: in some cases, users are required to enter boolean operators during a search. emory university library’s opac automatically executes “same” for multiple search words if no boolean operators are entered which means that it will find records with the search terms in the same bibliographic fields. syracuse university’s opac automatically uses the boolean operator “or” for all keyword queries. this practice can generate too many irrelevant results. libraries that automatically supply the boolean operator “and” for multiple terms entered in the search box consequently produce more relevant results. in addition, none of the arl opacs studied handle auto-correction for typos, spell-check, auto-plurals, auto-word-truncation, punctuations, or special characters. this makes searching unnecessarily inconvenient. for many years now, teaching students how to properly use boolean operators has been one of the essential topics in information literacy classes. after taking these classes, do students use boolean operators when searching? a study of 2,374 transaction logs collected by 836 french universities revealed that french university students use boolean operators infrequently. fifty-six percent of the queries used only a single term. approximately 28 percent of the queries contained one boolean operator. to further investigate the impact of information search expertise on the use of boolean operators, the study showed that approximately one-third (32 percent) of the students (considered the “novice” group in the study) still did not use boolean operators even when they were explicitly invited to do so, compared to 83 percent of librarians (considered the “expert” group in the study), who used at least one boolean operator for their queries.15 therefore, complicated search strategies and syntax are mostly used by expert users. novice users 8 information technology and libraries | march 20088 information technology and libraries | march 2008 prefer to use natural-language queries. libraries also handle phrase searching in different ways. phrase searching usually is embedded within keyword search either explicitly or implicitly depending upon the ils system. aleph (ex libris) libraries use a radio button for “word or phrase” or “words adjacent” or “exact phrase” options for the computer to execute the command. unicorn (sirsi/dynix) libraries provide three options: “keyword,” “begins with,” and “exact.” some libraries have the “exact” command executed to search every field in a bibliographic record; other libraries search the title, subject, and author fields only. the millennium system’s (innovative) keyword search feature can do automatic phrase and “and” search. some millennium libraries (e.g., michigan state university) take advantage of this feature to search words entered as phrases first and, if unsuccessful, the system then repeats the search for the same words using the boolean operator “and.” this feature produces more relevant search results. however, several millennium libraries have not implemented this feature. they still use “boolean keyword” search as the default and instruct users to add quotation marks to define phrases. the voyager (ex libris, formerly endeavor) system offers two types of keyword searches: “keyword relevance” and “keyword boolean.” both options can handle phrase searching. but users are required to enter quotation marks for specific terms used as phrases. some libraries intentionally made only one keyword search option available. other libraries provided both options and used different languages as an opac search key (see appendix b). these search keys are not self-explanatory, and users will often find them puzzling. the default help screen provided by the ils vendor and adopted by many voyager libraries does not help much either (see appendix c). thirty-one of the 35 voyager libraries provide a boolean keyword search option. only five libraries utilize the automatic “and” feature. one library uses boolean keyword search as the only keyword option, but did not activate the automatic “and” functionality. relevance ranking in search results when users search by keyword, the best way to sort the results is by relevance. presenting the most relevant results at the top of the results page is crucial because it enhances library resource discovery and access. other sorting options, such as title or publication date, are not very useful since users usually do not have titles or publication dates in mind when browsing search results from a keyword search. three ils systems (millennium, unicorn, and voyager) have a relevance-ranking feature, yet this functionality was very much underutilized by the libraries studied. of the eighteen unicorn libraries, only five offered relevance ranking. none made it the default sorting option. thirtysix of the 38 millennium libraries provided relevance ranking as a sorting option. only twelve of those libraries made relevance ranking the default sorting system. twenty-seven out of the thirty-five voyager libraries offered the keyword (relevance) search option, under which the search results were automatically ranked by relevance. out of the twenty-nine voyager libraries that offered the keyword (boolean) search option, only four libraries used relevance as the default sorting system. the rest of the libraries used a “system sort” mechanism that sorted search results by bibliographic control number. figure 1 summarizes the sorting options used by the arl libraries studied and also shows the default sorting options for keyword search. unlike online search engines, which pull data directly from full-text documents, library opacs search for words from the structured metadata entered by catalogers. different fields are set to carry different weights for relevance considerations. the behind-the-scenes algorithm (the criteria used to decide the level of relevance) should be carefully established to warrant a good ranking scheme. for example, the new opac of north carolina state university library, powered by endeca, adopted an algorithm based on field weighting, phrase matching, facet lcsh, term frequency (tf), and inverse document frequency (idf). their search results are indeed more logically ranked by relevance. recently there have been suggestions to incorporate circulation statistics, book review data, and a library of congress call number table into the algorithm. the checkout data would provide a rough substitute for google’s pagerank (a count of links to a site, which is an indication of the site’s popularity), and book reviews would provide more text to be considered in the relevancy tests. using library of congress call numbers would either require having the call number table loaded and then running the search terms against it or including call numbers in the algorithm, giving more weight to titles having the same call number. for example, seven out of twenty-three results generated for a search for “new york history” on an opac have the call number “f128.” the call number “f128” is linked to the call number table with the subject new york and history. it can be confirmed that seven items with call number “f128” should be considered more relevant and ranked first on the results list. more research needs to be done in this area. the search results display the search results display is critical. the information, options, and bibliographic data presented on the browse page help users decide what actions to take next. in the opacs examined, the authors found the following problems: article title | author 9revitalizing the library opac | mi and weng 9 1. search terms and search boxes were not retained on the results page after a search is performed, many opacs do not effectively carry the original search information onto the results screen. this information includes the search key and the words typed in the search box. users need to consult this information to identify and select records relevant to their needs from the search results page. based on the retained information, users also decide what to do next. for example, they might change their search strategy or modify their previous search. many of the opacs studied neglected to display the original search information. even better than just displaying the text of the user’s search terms would be to maintain them in search boxes at the top and bottom of the results display page. this way, users would only have to modify their search terms rather than type new search terms each time they wished to modify their original search. only one of the twentyone aleph libraries studied kept the previous search terms in the search box on the results page. fourteen of the aleph libraries retained neither the previous search strategy nor the search terms. six libraries placed the search box at the bottom of the search results page, which could be easily missed. 2. post-search limit functions were not always readily available sometimes keyword searches produce an overwhelmopac sorting options for keyword search

keyword search (as of march 2007) 10 information technology and libraries | march 200810 information technology and libraries | march 2008 ing number of search results. since the relevance ranking functionality currently provided by ils vendors does not work very well, the best way to refine searches is to make effective search limit options available. limiting options such as format, language, date, availability, and location should be readily available on the results page. some ilss in our study hid this feature, either under a modified search link or an advanced search link. this made refining a search unnecessarily cumbersome. 3. item statuses were not available on the search results page in addition to bibliographic information, users also need to know whether an item they want is available. having the item status on the browse page is very helpful because users can skip the records that have been checked out. some libraries studied did not have this information on the results browse page. users needed to go to the individual bibliographic records to find out whether an item was available or not. a few libraries provided an added-value option to limit the results by “available items”—a very useful feature. 4. a lack of value-added information a book cover image conveys an impression of a book that words cannot. it can also help a user recognize a book he or she has seen previously. in addition to cover images, libraries can provide value-added and contextual information by linking those images to tables of contents, summaries, sample passages of text, and reviews. one way libraries provide value-added and contextual information is to link cover images to the library of congress’s table of contents page. another way is to link opacs to information obtained from syndetics.com, a company that provides cover images, tables of contents, summaries, author biographical information, and reviews. the ohio state university library not only adds the table of contents into the marc record, but also links the names of the authors of a particular resource to other works by the same authors. this is a great discovery tool for finding related resources, and it is especially helpful, since in the future opacs will be able to search not only books but also articles and other resources. 5. title links were misleading we found that several libraries’ opacs title links on the results page did not take users to the detailed bibliographic record, but instead directed users to an alphabetical title-browsing page. to get to the actual bibliographic record, users had to click a “display full record” link (which is sometimes difficult to locate) to view the individual bibliographic record. this misleading feature makes the retrieval process inefficient. 6. switching between individual records and the results list was cumbersome after viewing an individual bibliographic record, users will want to return to the results browse page, either by hitting the “back” button or by clicking on a “return to results” link. many library opacs in our study returned the user to the top of the results page rather than to the location to which the user had previously scrolled. this forced the user to scroll back down through the records that had already been examined. this feature ought to be improved. 7. the color of entry links that had already been read were not differentiated for over a decade now, web browsers have changed the color of links that have already been clicked on. however, this has not been the case with opacs. to solve this problem, visited bibliographic entry links on search results pages should likewise be given a different color from entries that have not yet been visited. this feature facilitates the browsing of the search results. if what has been viewed is clearly marked, users only need to focus on entries that have not yet been visited. some libraries in our study did not have this feature. 8. searched keywords were not highlighted when a keyword search is performed, highlighting the entered keywords in each bibliographic record that has been retrieved is helpful. based on the bibliographic elements in which the highlighted keywords appear, users can then decide how relevant the retrieved publication is to their research. all five ils vendors provide this feature, and many libraries did a good job of implementing it. however, some libraries neglected to make this feature available. 9. many libraries lack a meaningful call-number browse feature library opacs should take better advantage of call number links by allowing users to browse them much as if they were browsing shelves in the stacks. to that end, opacs should link call numbers directly to a page with more useful identifying information, such as the authors and titles. no aleph library opacs that we studied currently have this feature. instead, clicking on the hyperlinked call number field only leads users to a list of more call numbers, which is not helpful at all. 10. title link, subject link, and author link should be relabeled to be meaningful to end users (other valueadded features) millennium’s “similar records” and voyager’s “more like this” are added to pull similar titles under the same article title | author 11revitalizing the library opac | mi and weng 11 subjects. unicorn and horizon offer a panel on the left side of the detailed book record, which can add meaningful information to these links. but how the panel is used depends on the individual libraries. some libraries use the panel with only library holding information, but other libraries, such as university of virginia, make an informative presentation of those links to students. virginia has added three browse features to make the index links much more meaningful: “find more by this author” (author link), “find more on these topics” (subject link), and “nearby items on shelf” (call number link). (see figure 2.) this value-added feature can indeed facilitate retrieval process. by analyzing five major integrated library systems’ opacs among arl libraries, the authors have come to believe that librarians can make a big difference in improving opacs. no matter how good the library system is, librarians still need to invest effort, time, and technical knowledge to configure and take full advantage of the many capabilities that ilss offer. public services, technical services, and system librarians should all work together to continuously study the usability of opacs and to make them more effective. it is true that all current opacs lack spell-check and automatic stemming functionality. aleph and horizon need to add relevance ranking, and millennium, unicorn, and voyager should make our data work harder and relevance ranking algorithms more effective. besides those systems in need of improvements, the study shows that all library opacs could do a much better job if they focus on the user’s needs. ■ the opac bibliographic display study when the web opac was introduced, libraries around the world quickly abandoned the traditional card catalog display and adopted the line-by-line display with display labels on one side and bibliographic information on the other. because the line-by-line display format can be locally customized, each library’s opac bibliographic display looks very different. for decades, most academic libraries in the united states have used aacr and marc as their content and metadata standards for resource description and access. marc and aacr were originally created for card catalogs in which descriptive elements and access elements were separately defined and presented. the line between the two types of elements has become less distinct in today’s web environment. many elements in bibliographic records can serve as both description and tracing elements on opacs.16 hyperlink functionality has also streamlined the retrieval process. to see how academic libraries in the united states format their opac bibliographic displays, the authors examined the opacs of fifteen academic libraries.17 the purpose was to study the effectiveness of the display of records in different formats. in the mid-1990s, wool studied the bibliographic display practices for monographs of thirty-six online catalogs in the united states. in his study, five criteria were used to analyze each bibliographic record structure.18 the authors of this paper adopted for analysis three of the five opac bibliographic display criteria used by wool, only this time with an emphasis on the user’s perspective and needs. eight different titles were reviewed and compared: three monographs, two serials, one video recording, and two sound recordings.19 the analysis given below is based on the following three criteria: ■ the accuracy and clarity of display labels; ■ the order of bibliographic elements display; and ■ the utilization of bibliographic data. accuracy and clarity of display labels for this discussion, the authors divided the bibliographic elements into three areas: ■ the first tier: information about author/contributor, title, imprint, and subjects; ■ the second tier: other descriptive information, including the physical description, notes, related contributors, related titles, etc.; and ■ the third tier: the linking fields (marc 76x–78x fields) and the electronic location and access field (i.e., 856 field). the first-tier elements the information displayed in the first tier can be consid-figure 2. university of virginia libraries catalog 12 information technology and libraries | march 200812 information technology and libraries | march 2008 most libraries in our study used the label “author” for the principal author. the principal author could be a personal author, a corporate author, or a conference name. if it is a personal author, it could be a writer, an artist, or a composer. some opacs used “author” to represent all types of responsible bodies, be it a personal author, a corporate author, a meeting name, an artist, a music composer, etc. this use of a single label to cover a diverse set of situations is confusing. some libraries used separate labels (“author,” “corporate author,” “meeting name,” “author/ artist,” “author/composer,” or “author, etc.”) for different types of responsible bodies (see appendix d). “uniform title” was defined in aacr to collocate resources derived from the same original intellectual or artistic creation. for example, when cataloging a translation, in addition to its official translated title, an established uniform title is entered to indicate the original work. when browsing by uniform title on a properly set opac, all entries related to the original intellectual creation should be retrieved. this uniform title browsing feature helps users locate related publications in the catalog. the problem is that the term “uniform title” is only understood by catalogers, not by others. there is no label for such an entry that can be easily understood by the average user. however, suppressing the uniform title entry to avoid confusing users will cause the opac to lose its helpful collocation functionality. some libraries studied use the term “uniform title” as a display label. some libraries use “other title” as a display label. some libraries display this entry under the label “title” along with the title proper (title in the 245 field). none of the above-mentioned arrangements are ideal. the display labels for subject headings provided by each library were very similar. most academic libraries in the united states use the library of congress subject headings and the medical subject headings as the thesauri for subject entries. specifying the thesauri for headings on opacs with acronyms like “lcsh” and “mesh” is of no help to users, because these thesauri do not clarify anything that would assist users in their research. figure 3 lists the display labels used by libraries in the study. ered the key elements for identification. opac users first examine them and decide if the manifestation described is relevant to their query. most opacs studied used “title” as the display label for the title statement. this element actually consists of the title and statement of responsibility (author, etc. statement). using the label “title” alone is not inclusive enough. one library (university of arizona library) displayed only the title portion under the label “title” and provided a separate label, “author/contributor info,” for the statement of responsibility portion, which, while helpful in a limited way, could also create more confusion. let us consider, for example, the project directory (répertoire des projets) of tdc (in french, cdt). the title statement for this data would be “project directory / tdc = répertoire des projets / cdt.” here, the english title and statement of responsibility is equivalently presented with its french title and statement of responsibility. the opac display using the university of arizona library’s model is as follows: title: project directory author/contributor info: tdc = répertoire des projets / cdt. this arrangement will not work for items with titles and statements of responsibility in multiple languages presented on a single manifestation. the french title appears under the label “author/contributor info,” which makes no sense. marc fields library of congress subject (marc 650 field 2nd indicator 0) medical subject (marc

mi and weng 13 the second-tier elements the elements in the second tier include the physical description, notes, related authors, and related titles. this is an area where mapping bibliographic elements onto proper display labels is difficult. this area was also not managed well by the libraries studied. unlike first-tier elements in which one element usually corresponds to a unique display label, second-tier elements exhibit two patterns in the opacs examined: many-to-one and one-to-many. that is, multiple categories of data (of different marc fields) can be represented by one display label, e.g., incorporating physical description, numbering notes, and publication numbering into “description” (many-to-one). on the other hand, one display label can represent one single, repeatable bibliographic element (the same marc field repeated many times), e.g., multiple general notes (oneto-many). both arrangements (one-to-many and manyto-one) can result in a simpler, cleaner public display, since some descriptive elements are self-explanatory and users can get by without specific display labels supplied. the disadvantage of these arrangements is that the level of specificity of public displays is compromised. some important descriptions can be easily missed if they are clustered in a group of elements. for bibliographic elements that are not self-explanatory, this type of arrangement can fail to convey useful information, or even worse, deliver inaccurate or vague information. for example: description: v. : ill. ; 28 cm (physical description, marc 300 field) report year ends mar. 31. (numbering note, marc 515 field) ’77– (publication span, marc 362 field) published: philadelphia : robert morris associates, 1977– (imprint, marc 260 field) ’77– (publication span, marc 362 field) annual (frequency, marc 310 field) the numbering field (field 362) is defined to describe a serial publication’s chronological or numerical publication extent. carelessly placing data like “’77-” under labels such as “description” or “published” is very unclear. in fact, it is inaccurate because “’77-” is the publication span, not the publication date. without a proper label, it is difficult to convey this information to users. some libraries we studied used such labels as “publication history,” “publishing history,” “publication dates,” or “volume/date range” to describe the publication span. this practice is misleading (see appendix e). names like coauthors, editors, cast members, performers, related corporate names, or meeting names of people who contributed to or were involved in the creation of the work are considered secondary contributors. using one label to cover the various roles (author, editor, composer, etc.) is the practice most libraries have adopted. like the primary author field, this element represents a variety of roles depending upon the type of manifestation. some opacs used one display label to cover all related personal names, corporate names, and meeting names (see appendix f). most libraries failed to supply a proper label for a secondary name when it was entered with a related title. this so-called “name-title added entry” is provided to collocate materials under the same author and title in the catalog. ideally, the name-title combined element, provided with redirect functionality via hyperlink, should perform an author-title combination search for exact retrieval. most opac systems could only perform either an author or a title search. the search results were unsurprisingly irrelevant, because they did not utilize both elements of the name-title added entry to produce results that were sufficiently specific: users would get only a list of authors or a list of titles instead of an author-title combination entry list. some libraries presented this type of element only as an unhyperlinkable note, which defeats the purpose of having such data available. handling series for opac displays is also challenging. the majority of opacs studied did a poor job in this area. in general, a series title transcribed from the resource also functions as an access element if the transcribed title is the same as the established one in the authority file. when the transcribed series title is different from the established series title, ideally the transcribed series title should only be accessible via the library system’s cross-references feature, which then directs users to bibliographic records that contain the established entry. this type of descriptive element is not meant to be displayed on the opac. the opacs examined used the labels listed in figure 4 to handle transcribed and established series entries. labels listed in the same row were taken from the same opac. as can be seen, users are not expected to know the difference between a “series statement” and a “series.” in many cases, these two elements are identical due to the vendor authority control process.20 this could confuse the user, especially when both elements are displayed right next to each other. 14 information technology and libraries | march 200814 information technology and libraries | march 2008 the third-tier elements the third-tier elements consist of linking fields (marc 7xx fields) and electronic location and access fields (marc 856 field). the linking fields are used mostly in serial bibliographic records. their purpose is to link the title being described to its related publications, e.g., supplements, translations, preceding titles, or succeeding titles. elements in this category should be displayed and linked directly to the related record via control numbers provided in the bibliographic record. if the catalog does not have the related record, a clear message should indicate this to the user. unfortunately, many libraries do not display all the linking entries. none of the opacs studied offered direct link functionality. instead, what was usually offered was a redirect feature via hyperlink that prompted the system to issue a new author or title search. the direct link functionality via record control numbers was never made available. if the library did not have the related entry, the opac system simply took the user back to the original entry—a very confusing design flaw. to ease the user’s access to internet resources, the electronic location and access element (marc 856 field) was defined for catalogers to record the internet location of the resource being described and its related information. by clicking the hyperlinked element on an opac, users seamlessly get to the desired electronic document site. the url specified in the field might link to full-text documents, the table of contents, the document abstract, the publisher’s description, or the author’s biographical information. a label that fits all types of materials is crucial. the bibliographic elements displayed under the label should also be carefully managed. under the label, some libraries displayed the type of resource (e.g., table of contents). other libraries displayed the http url only. some libraries displayed both the type of resource and the http url (see figure 5). as for the location of the label in the opac record, we found that the location of the url link depended on the opac in which it appeared: in some opacs, links were located at the top of records; in others, they appeared in the middle or at the bottom. we found that the location of the link was not terribly critical, provided that the label was prominent and the display text understandable. the order of the bibliographic elements display the way bibliographic data is organized in each opac record, together with display labels, helps users to quickly identify library resources. although each library can locally choose the arrangement of bibliographic data displayed on its opac, most libraries prefer to place the citation information (author, title, publication) ahead of other elements. the sequence of the other elements exhibited enormous variation in the opacs studied. some libraries placed the electronic access element above all other data (suny buffalo); some libraries placed local holdings information, call number, and item availability in the middle of the bibliographic record. arrangements were clearer and more understandable when provided with clear labels and a distinct layout between the local holdings information and bibliographic data. problems arose when second-tier elements were mingled with firsttier elements and when they shared the same display label. see example in figure 6. in this example, two titles are displayed under the “title” label. the first title, “rma annual statement studies,” is the full title (marc field 245) of the publication. the second title, “rma annual statement studies: industry default probabilities and cash flow measures,” is the title of the resource’s related publication (marc field 730), which normally is considered a second-tier element and should be placed farther from the title proper with a clear label. since the display order of bibliographic elements is completely customizable, we found in our study that few libraries put enough effort into providing clear bibliographic displays. more importantly, records in different formats (e.g., monographs, serials, music materials, video recordings) were not given equal attention. some labels and data sequences might work for one format, but not another. utilization of bibliographic data another factor that has an effect on the usability of an opac is the utilization of bibliographic data. two issues are addressed in terms of utilization of bibliographic data: (1) the completeness and suitability of the metadata displayed on an opac, and (2) the extent of repurposing the bibliographic data and creating added value to an opac.21 a typical bibliographic record contains descriptive data, access data, and adminlabel for transcribed element label for established element series statement series series statement series indexed as other series series series note series description series figure 4. display labels for series article title | author 15revitalizing the library opac | mi and weng 15 istrative data. descriptive data is provided to describe the manifestation cataloged and is considered of interest to the public. access data is entered and indexed for retrieval. administrative data is used for setting up search limits (e.g., limit by language, format) and pulling statistics (e.g., how many titles in spanish). it is most useful for internal, administrative use. librarians must be careful when deciding whether such data elements will be displayed. in terms of the completeness and the suitability of metadata in the opac display, the authors discovered the following in the opacs studied: 1. many libraries’ opacs displayed control numbers, such as the oclc control number (the 035 field), the lc control number (010 field), and other local system control numbers. this type of information is usually of no interest to the public. see example in figure 7. in this example, the numbers listed under the label “wln #” represent different types of system control numbers, which are of no concern to users and therefore should not be displayed. 2. some opacs displayed bibliographic data from the leader fields of the cataloging record. marc leader fields are a group of fixed-length codes that represent the type of resource (monograph, serial, or musical score) and material format (print, electronic, or sound recording). the information could be helpful for patrons if they are displayed with the proper label on the opac. libraries that chose to display the leader data on their opacs did not do a good job of making the information clear to users. for example, one library listed “journals and newspapers,” “computer file,” “serial,” “book,” “e-resource,” and “gov publication” under the label “record type” (see figure 8). seeing so many record types under one label can easily confuse library users. 3. some libraries omitted certain crucial variable fields, e.g., the linking entry complexity note (field 580, containing information about title history), related title access entries (fields 730 and 740, containing related titles), and linking entries (linking the record to other bibliographically related records, e.g., 76x, 77x, and 78x fields). these fields are defined with a clear purpose and should be carefully considered for public display with clear labels. some libraries in our study displayed them but left other irrelevant information on the opac, which clutters the display with information that does not help users. see example in figure 9. in this example, under the label “related publication,” the french version and the spanish version of jama are displayed. in addition to the french title and the spanish title, the marc 21 language code and its corresponding issn are also displayed. the language code and the eight-digit issn number— since no separate label is provided for them—are confusing. 4. the linking elements not only should be displayed on the opac, but should also be hyperlinkable. they ought to be used to link to related bibliographic records. in an online environment, this sort of field can also function as a descriptive element. some opacs displayed linking entries but did not enable hyperlink functionality. some libraries displayed two instances of them, one as a descriptive element and the other as a linking element with hyperlink capability. another important aspect of making use of bibliographic data is repurposing the bibliographic data to provide added value to opacs. lorcan demsey mentions frequently in his blog that in order to sustain library value, libraries should “make data work harder.” he points out that “libraries have invested a great deal in bibliographic data—yet it has remained somewhat inert in our catalogs, failing to release the value of the investment.”22 these rich data can be better utilized for different purposes, including designing an enhanced opac. lavoie, et al. described further in their recent article about data mining: as more activities move into networked spaces, more areas of our lives are shedding data. this data is increasingly being mined for intelligence that drives services. . . . [c]ompanies like amazon repurpose data to create added value. this is a lesson librarians must learn if they want to improve their own visibility and value in increasingly crowded digital information spaces where users, as always, want good results without too much time or effort. . . . the good news is that libraries don’t come to this task empty-handed but with figure 5. online opac record from suny buffalo figure 6. online opac record from the college of new jersey 16 information technology and libraries | march 200816 information technology and libraries | march 2008 rich, structured information about the materials in our collections.23 tim o’reilly highlighted in his article the successful example of how amazon reutilizes data: amazon relentlessly enhanced the data, adding publisher-supplied data such as cover images, table of contents, index, and sample materials. even more importantly, they harnessed their users to annotate the data, such that after ten years, amazon, not bowker, is the primary source for bibliographic data on books, a reference source for scholars and librarians as well as consumers. . . . effectively, amazon “embraced and extended” their data suppliers.24 all opacs reviewed in the study operate within the traditional vendor-supplied module. this long-established approach gives libraries limited flexibility to customize the search key options, search results displays, restricted sorting options, and preand post-search limit options of their opacs. unfortunately, libraries can do very limited data mining inside the vendor’s hard-coded framework. many valuable metadata are buried in the bibliographic database. system vendors have failed to make the most of technology to better utilize data. very few libraries have thought outside the box and taken advantage of the existing rich bibliographic data. the emergence of north carolina state university’s endecapowered opac was a good example of repurposing data and creating value-added information. the data facets used on ncsu’s single search-andbrowse combined opac interface are pulled and repurposed from their sirsi/dynix database. as one might have expected, eight of the eleven facets are extracted from the library’s marc bibliographic records (“availability” and “browse: new” are from item records). out of the eight facets, four are extracted from subject headings; two are from the fixed fields; one is from the call number field and one from the variable fields of the bibliographic record.25 ■ discussion and recommendation based on the authors’ findings above, the following are the primary factors that have contributed to the ineffectiveness of the opacs offered by today’s academic libraries. 1. system limitations the inadequacy of today’s ils has been a known problem. inflexible search options make library catalogs difficult to use. despite the fact that some vendors diligently enhance their systems’ functionalities, overall performance is still disappointing. karen markey pointed out in a recent article that one of the reasons why the solutions recommended by researchers in the 1990s were not applied to online library catalogs was “the failure of ils vendors to monitor shifts in information-retrieval technology and respond accordingly with system improvements.”26 antelman et al. observed similarly that all major ils vendors are still marketing catalogs that represent second-generation functionality. despite between-record linking made possible by migrating catalogs to web interfaces, the underlying indexes and exact-match boolean search remain unchanged. it can no longer be said that more sophisticated approaches to searching are too expensive computationally; they may, however, to be too expensive to introduce into legacy systems from a business perspective.27 since ils vendors first introduced their products back in the 1980s, user behavior and expectations have changed immensely. while libraries have started to figure 7. online opac record from the university of washington. figure 9. online opac record from the university of michigan.figure 8. online record from suny buffalo article title | author 17revitalizing the library opac | mi and weng 17 recognize the changes and are working hard toward meeting the needs of multiple generations of users, little can be done if ils products still operate within the same old-fashioned information-retrieval structure. because ils vendors have failed to revamp their opac modules to meet user needs, libraries have been forced to seek other options. north carolina state university is one of the first libraries to exercise its options. its new opac system, powered by endeca (operated on the sirsi/dynix platform), has shown remarkable improvements in ease of use, which usability tests have verified. recently, two ils vendors (innovative and ex libris) have been in the process of developing new opac modules using new technology and a new approach in data mining. 2. libraries are not fully exploiting the functionality already made available by ilss unsurprisingly, the opacs examined by the authors, if powered by the same vendor, showed similarities in general layout and interface features. during the study, it soon turned out to be easy for the authors to recognize the ils system of each opac. as mentioned previously, we expected opacs to vary somewhat. what was unexpected was the huge differences in, among other things, interface layout, search options and search languages, behind-thescenes search algorithms, search results displays, display labels and the corresponding bibliographic data, and what data was chosen for display. the disparities that we found in these features suggested that there had been great differences in the amount of attention, energy, and time devoted by each library to designing its opac. some libraries took advantage of available features and made better use of them than others. (see appendix g for examples of best practices of library opacs.) many libraries did only the very minimum. while we recognize that academic library opacs are difficult to use, we also need to recognize that some libraries do not fully exploit existing resources, thereby exacerbating the difficulty of using their opacs. 3. the unsuitability of marc standards to online bibliographic display as previously mentioned, aacr and marc were initially designed for card catalogs without display labels in mind. many marc fields can be used for multiple purposes. providing labels that properly fit all the cataloging data needed to cover all types of resources is nearly impossible. from the opacs studied, some libraries used vague labels in an effort to encompass as many circumstances as possible. some libraries used labels suitable only for certain formats, but not all formats. neither approach is satisfactory. the solution has to come from cataloging and metadata standards. wool identified this issue back in the 1990s: the interchangeability of descriptive data elements and access points (since each can be made to serve both functions online) makes the separate creation of description and headings seem pointless and burdensome. labeling of data elements (made possible through the mapping of terms to marc fields) creates a need for simpler, less ambiguous bibliographic data definitions than are appropriate for the dense and context-rich narrative-style records catalogers continue to create . . . cataloging standards will need to be rewritten in order to provide the kind of data flexibility expected in online systems . . . records flexible enough to be added to, subtracted from, and rearranged without loss and garbling of meaning. what is needed is a modular record structure, in which every segment of data can stand on its own with appropriate labeling and which can support all possible display lengths and combinations of data elements.28 a decade later, not much progress has been made in improving cataloging and metadata standards for online display. while enhancing cataloging and metadata standards for better retrieval is desirable, making the standards more complicated and difficult to adopt in order to accommodate opac displays is not. as librarians are working to simplify cataloging, our essential rich metadata should not be sacrificed. one possible solution is to have the system recognize the existence of certain subfields and produce specific display labels accordingly. this certainly will not solve all the issues with regard to display labels. regardless, there is much room for improvement, and librarians’ attention is this area is critically needed. ■ conclusion the information-seeking world has entered an era of selfservice. roy tennant described well the self-service trend: “i wish i had known that the solution for needing to teach our users how to search our catalog was to create a system that didn’t need to be taught.”29 tim o’reilly also indicated in his article “what is web 2.0” that “the web 2.0 lesson [is to] leverage customer-self service and algorithmic data management to reach out to the entire web, to the edges and not just the center, to the long tail and not just the head.” he also argued that “[t]rusting users as co-developers” is one of the core competencies of web 2.0 companies.30 academic libraries should aim toward designing a user-centered, self-sufficient, twenty-first-century online catalog that fits the web 2.0 model. the ultimate goal is that users will be comfortable and confident using library opacs for their information needs wherever a computer 18 information technology and libraries | march 200818 information technology and libraries | march 2008 is available and without special training. as campbell and fast have trenchantly asked, “are we witnessing a major disruption, a large-scale redefinition of information design and delivery so radically different from the traditional library environment that it renders irrelevant all our experience in bibliographic control?”31 this remains an open question. regardless, a new generation of opacs will need to be in place soon. much needs to be done to make academic library opacs matter. academic librarians cannot afford to be considered irrelevant in the information-seeking world. the future of academic libraries relies on effective opacs. this is one of the most pressing tasks that must be accomplished. references and notes 1. cathy de rosa et al., perceptions of libraries and information resources:

et al. 75 here again, no weighting or differentiating mechanism is included in describing the multiple elements. what is addressed is the “what” problem: what is the work of or about? metadata schemas for images and art works such as vra core and cdwa focus on specificity and exhaustivity of indexing, that is, the precision and quantity of terms applied to a subject element. however, these schemas do not address the question of how much the work is of or about the item or concept represented by a particular keyword. recently, social tagging functions have been adopted in digital library and catalog systems to help support better searching and browsing. this introduces more subject terms into the system. yet again, there is typically no mechanism to differentiate between the tags used for any given item, except for only a few sites that make use of tag frequency information in the search interfaces. as collections grow and more federated searching is carried out, the absence of weights for subject terms can cause problems in search and navigation. the following examples illustrate the problems, and the rest of the paper further reviews and discusses the precedent research and practice on weighting, and further outlines the issues that are critical in applying a weighting mechanism. example, the dublin core metadata element set recommends the use of controlled vocabulary to represent subject in “keywords, key phrases, or classification codes.”1 similarly, the library of congress practice, suggested in the subject headings manual, is to assign “one or more subject headings that best summarize the overall contents of the work and provide access to its most important topics.”2 a topic is only “important enough” to be given a subject heading if it comprises at least 20 percent of a work, except for headings of named entities, which do not need to be 20 percent of the work when they are “critical to the subject of the work as a whole.”3 although catalogers are aware of it when they assign terms, this weight information is left out of the current library metadata schemas and practice. a similar practice applies in non-textual object subject indexing. because of the difficulty of selecting words to represent visual/aural symbolism, subject indexing for art and cultural objects is usually guided by panofsky’s three levels of meaning (pre-iconographical, iconographical, and post-iconographical), further refined by layne in “ofness” and “aboutness” in each level. specifically, what can be indexed includes the “ofness” (what the picture depicts) as well as some “aboutness” (what is expressed in the picture) in both pre–iconographical and iconographical levels.4 in practice, vra core 4.0 for example defines subject subelements as: terms or phrases that describe, identify, or interpret the work or image and what it depicts or expresses. these may include generic terms that describe the work and the elements that it comprises, terms that identify particular people, geographic places, narrative and iconographic themes, or terms that refer to broader concepts or interpretations.5 seeing the wood for the trees: enhancing metadata subject elements with weights subject indexing has been conducted in a dichotomous way in terms of what the information object is primarily about/of or not, corresponding to the presence or absence of a particular subject term, respectively. with more subject terms brought into information systems via social tagging, manual cataloging, or automated indexing, many more partially relevant results can be retrieved. using examples from digital image collections and online library catalog systems, we explore the problem and advocate for adding a weighting mechanism to subject indexing and tagging to make web search and navigation more effective and efficient. we argue that the weighting of subject terms is more important than ever in today’s world of growing collections, more federated searching, and expansion of social tagging. such a weighting mechanism needs to be considered and applied not only by indexers, catalogers, and taggers, but also needs to be incorporated into system functionality and metadata schemas. s ubjects as important access points have largely been indexed in a dichotomous way: what the object is primarily about/ of or not. this approach to indexing is implicitly assumed in various guidelines for subject indexing. for hong zhang, linda c. smith, michael twidale, and fang huang gaocommunications hong zhang

problems exhaustive indexing: digital library collections a search query of “tree” can return thousands of images in several digital library collections. the results include images with a tree or trees as primary components mixed with images where a tree or trees, although definitely present, are minor components of the image. figure 1 illustrates the point. these examples come from three different collections and either include the subject element of “tree” or are tagged with “tree” by users. there is no mechanism that catalogers or users have available to indicate that “tree” in these images is a minor component. note that we are not calling this out as an error in the professionally developed subject terms, nor indeed in the end user generated tags. although particular images may have an incorrectly applied keyword, we want to talk about the vast majority where the keyword quite correctly refers to a component of the image. furthermore, such keywords referring to minor components of the image are extremely useful for other queries. this kind of exhaustive indexing of images enables the effective satisfaction of search needs, such as looking for pictures of “buildings, people, and trees” or “trees beside a river.” with large image collections, such compound needs become more important to satisfy by combinations of searching and browsing. to enable them, metadata about minor subjects is essential. however, without weights to differentiate subject keywords, users will get overwhelmed with partially relevant results. for example, a user looking for images of trees (i.e., “tree” as the primary subject) would have to look through large sets of results such as a photograph of a dog with a tiny tree out of focus in the background. for some items that include rich metadata, such as title or description, when people look at a particular item’s record, with the title and sometimes the description, we may very well determine that the picture is primarily of, say, a dog instead of trees. that is, the subject elements have to be interpreted based on the context of other elements in the record to convey the “primary” and “peripheral” subjects among the listed subject terms. however, in a search and navigation system where subject elements are usually treated as context-free, search efficiency will be largely impaired because of the “noise” items and inability to refine the scope, especially when the volume of items grows. lack of weighting also limits other potential uses of keywords or tags. for example, all the tags of all the items in a collection can be used to create a tag cloud as a low cost way to contribute to a visualization of what a collection is “about” overall.6 unfortunately, a laboriously developed set of exhaustive tags, although valuable for supporting searching and browsing within a large image collection, could give a very distorted overview of what the whole collection is about. extending our example, the tag “tree” may occur so frequently and be so prominent in the tag cloud that a user infers that this is mostly a botanical collection. selective indexing: lcsh in library catalogs although more extreme in the case of images in conveying the “ofness,” the same problem with multiple subjects also applies to text in terms of “aboutness.” the following example comes from an online library catalog in a faceted navigation web interface using library of congress subject headings in subject cataloging.7 the query “psychoanalysis and religion” returned 158 results, with 126 in “psychoanalysis and religion” under the topic facet. according to the subject headings manual, the first subject is always the primary one, while the second and others could be either a primary or nonprimary subject.8 this means that among these 126 books, there is no easy way to tell which books are “primarily” about “psychoanalysis and religion” unless the user goes through all of them. with the provided metadata, we do know that all books that have “psychoanalysis and religion” as the first subject heading are primarily about this topic, but a book that has this same heading as its second subject heading may or may not be primarily about this topic. there is no way to indicate which it is in the metadata, nor in the search interface. as this example shows, the library of congress manual involves an attempt to acknowledge and make a distinction between primary and nonprimary subjects. however in practice the attempt is insufficient to be really useful since apart from the first entry, it is ambiguous whether subsequent entries are additional primary subjects or nonprimary subjects. consequently, the search system and, further on, the users are not able to take full advantage of the care of a cataloger in deciding whether an additional subject is primary or not. other information retrieval systems the negative effect of current subject indexing without weighting on search outcomes has been identified by some researchers on particular information retrieval systems. in a study examining “the contribution of metadata to effective searching,”9 hawking and zobel found that the available subject metadata are “of little value in ranking answers” to search queries.10 their explanation is that “it is difficult to indicate via metadata tagging the relative importance of a page to a particular topic,”11 in addition to the problems in data quality and system implementation. the same problem : | zhang et al. 77seeing the wood for the trees | zhang et al. 77 authors compared with the automatic indexing systems, because human indexers should be better at weighting the significance of subjects, and be more able to distinguish between important and peripheral compared with computers that base significance on term frequency.13 indeed, while various weighting algorithms have been used in automatic indexing systems to approximate the distinguishing function, there is simply no such mechanism built in human subject the particular page harder to find.12 a similar problem is reported in a recent study by lykke and eslau. in comparing searching by controlled subject metadata, searching based on automatic indexing, and searching based on automatic indexing expanded with a corporate thesaurus in an enterprise electronic document management system, the authors found that the metadata searches produced the lowest precision among the three strategies. the problem of indiscriminate metadata indexing is “remarkable” to the of multiple tags without weights is described: in the kinds of queries we have studied, there is typically one page (or at most a small number) that is particularly valuable. there are many other pages which could be said to be relevant to the query—and thus merit a metadata match—but they are not nearly so useful for a typical searcher. under the assumption that metadata is needed for search, all of these pages should have the relevant metadata tag, but this makes a. subject: women; books; dresses; flowers; trees; . . . in: victoria & albert museum (accessed aug. 30, 2010),

and libraries | june 2011 anderson in niso tr021997.20 in addition, researchers have noticed the limitations of this dichotomous indexing. in an opinion piece, markey emphasizes the urgency to “replace boolean-based catalogs with post-boolean probabilistic retrieval methods,”21 especially given the challenges library systems are faced with today. it is the time to change the boolean, i.e., dichotomous, practice of subject indexing and cataloging, no matter whether it is produced by professional librarians, by user tagging, or by an automatic mechanism. indeed, as declared by svenonius, “while the purpose of an index is to point, the pointing cannot be done indiscriminately.”22 needed refinements in subject indexing the fact that weighted indexing has become more prominently needed over the past decade may be related to the shift in the continuum from subject indexing as representation/ surrogate to subject indexing as access points, which is consistent with the shift from a small number of subject terms to more subject terms. this might explain why the weighting practice is applied in the above mentioned medline/pubmed system. with web-based systems, social tagging technology, federated searching, and the growing number of collections producing more subject terms, to distinguish between them has become a prominent problem. in reviewing information users and use from the 1920s to the present, miksa points out the trend to “more granular access to informational objects” “by viewing documents as having many diverse subjects rather than one or two ‘main’ subjects,” no matter what the social and technical environment has been.23 in recognizing this theme in the future development of information organization and retrieval systems, we argue that the subject indexing mechanism subject indexing has been discussed in the research area of subject analysis for some time. weighting gives indexing an increased granularity and can be a device to counteract the effect of indexing specificity and exhaustivity on precision and recall, as pointed out by foskett: whereas specificity is a device to increase relevance at the cost of recall, exhaustivity works in the opposite direction, by increasing recall, but at the expense of relevance. a device which we may use to counteract this effect to some extent is weighting. in this, we try to show the significance of any particular specification by giving it a weight on a pre-established scale. for example, if we had a book on pets which dealt largely with dogs, we might give pets a weight of 10/10, and dogs, a weight of 8/10 or less.16 anderson also includes weighting as a part of indexing in the guidelines for indexes and related information retrieval devices (niso tr021997): one function of an index is to discriminate between major and minor treatments of particular topics or manifestations of particular features.17 he also notes that a weighting scheme is “especially useful in high-exhaustivity indexing”18 when both peripheral and primary topics are indicated. similarly, fidel lists “weights” as one of the issues that should be addressed in an indexing policy.19 metadata indexing without weighting is related to the simplified dichotomous assumption in subject indexing—primarily about/of and not primarily about/of, which further leads to the dichotomous retrieval result—retrieved and not retrieved. weighting as a mechanism to break this dichotomy is noted by metadata indexing even though human indexers are able to do the job much better than computers. weighting: yesterday, today, and future precedent weighting practices written more than thirty years ago, the final report of the subject access project describes how the project researchers applied weights to the newly added subject terms extracted from tables of contents and backof-the-book indexes. the criterion used in that project was that terms and phrases with a “ten-page range or larger” were treated as “major” ones.14 a similar mechanism was adopted in the eric database beginning in the 1960s, with indexes distinguishing “major” and “minor” descriptors as the result of indexing. while some search systems allowed differentiation of major and minor descriptors in formulating searches, others simply included the distinction (with an asterisk) when displaying a record. unfortunately, this distinguishing mechanism is no longer included in the later eric indexing data. a system using weighted indexing and searching and still running today is the medline/pubmed interface. a qualifier [majr] can be used with a medical subject headings (mesh) term in a query to “search a mesh heading which is a major topic of an article (e.g., thromboembolism[majr]).”15 in the search result page, each major mesh topic term is denoted by an asterisk at the end. weighting concept and the purpose of indexing the weighting concept is connected with the fundamental purpose of indexing. the idea of weighting in : | zhang et al. 79seeing the wood for the trees | zhang et al. 79 user tagging and machine generated metadata, such weighting becomes more important than ever if we are to make productive use of metadata richness and still see the wood for the trees. references 1. “dublin core metadata element set, version 1.1,” http://dublincore.org/docu ments/dces/ (accessed

libraries | march 2019 14 brian rennick (brian_rennick@byu.edu) is aul for library it, brigham young university. abstract while the discoverability of traditional information resources is often the focus of library website design, there is also a need to help users find other services such as equipment, study rooms, and programs. a recent assessment of the brigham young university library website identified nearly two hundred services. many of these service descriptions were buried deep in the site, making them difficult to locate. this article will describe a web application that was developed to improve service discovery and to help ensure the accuracy and maintainability of service information on an academic library website. introduction the brigham young university library released a new version of its website in 2014. multiple usability studies were conducted to inform the design of the new site. during these studies, the web designers observed that when a user did not see what they were looking for on the homepage, they were likely to click on the “services” link as the next best option. the word services appeared to be an effective catch-all term. web designers asked themselves, “what is a library service?” they concluded that a library service could be anything public-facing that meets the needs of a user. using this broad definition, services could include: • library materials—both digital and physical (e.g. books, dvds) • material services (e.g. course reserve, interlibrary loan) • equipment and technology (e.g. computers, cameras, tripods) • help and guidance (e.g. research assistance, computer assistance) • locations (e.g. group study rooms, classrooms, help desks) • programs (e.g. friends of the library, lectures) because libraries offer so many diverse services, structuring a website to effectively promote them all brings many challenges. for instance, a common approach to presenting library services on a website is to have a menu that lists a few of the most popular or important services. the last menu item will normally be a link to a web page for “other services” that provides a more comprehensive service list. such an all-inclusive listing of library services on a single web page can easily lead to information overload for users. where do services belong in a library website’s information architecture? determining the one correct path is not easy because there are multiple valid ways to organize services into web pages. services could be arranged by department, service category, user group (undergraduates, graduates, faculty, visitors, alumni), or any number of other ways. an ideal system would allow users to follow the path that makes the most sense to them. information technology and libraries | march 2019 15 user expectations for a single (google-like) search box add to the challenges for service listings.1 a single search box, also known as a metasearch system, web-scale discovery service, or federated search, combines search results from multiple library sources. a study at the university of colorado found that users expected to locate services by entering keywords into the single search box on the library’s homepage.2 for example, the users attempted to search for “interlibrary loan” and “chat with a librarian” using the single search box. it is unrealistic to expect all users to follow a specific series of links in order to find the one correct path to information about a service when they are accustomed to google-style searching. even when a user manages to locate the correct web page where a service is described, the pertinent information can still be difficult to pinpoint when service descriptions are buried in paragraphs. users need to be able to quickly perform a visual scan of a web page to locate service information. kozak and hartley suggest that “bulleted lists are easier to read, easier to search and easier to remember than continuous prose.”3 the ongoing maintenance of service listings poses another significant challenge. for large academic libraries, up-to-date service information is difficult to maintain because it is typically scattered throughout a website. each department may have its own set of web pages and service listings. department pages created and maintained by different individuals end up with inconsistent design, organization, and voice. services that are common to multiple departments will have duplicate listings with different descriptions. maintenance of accurate information becomes an issue as services change; tracking down all of the references to a discontinued or modified service requires extensive searching of the website. literature review studies and commentaries regarding the information architecture of academic library websites have been covered extensively in the literature.4 a few articles specifically address the way that library services are organized on websites. library services are a significant component of academic library website content. clyde studied one hundred library websites from thirteen countries in order to compare common features and to determine some of the purposes for a library website.5 purposes for the sites varied. some focused on providing information about the library and its services while others functioned more like a portal, providing links to internet resources. cohen and still developed a list of core content for academic library websites by examining pages from university and two-year college sites.6 they organized the content into categories: library information, reference, research, instruction, and functionalities. liu surveyed arl libraries to get an overview of the state of web page development.7 the subsequent spec kit identifies services commonly found on academic library websites. yang and dalal studied a random sample of academic library websites to see which web–based reference services were offered and how they were presented.8 they also examined the differing terminology used to describe the services. the choice of terminology used on library websites impacts the findability of services. dewey compared academic websites from thirteen member libraries of a consortium to determine how findable service links were on the sites.9 the service links used in the evaluation covered “access, reference, information, and user education” categories. the study measured the number of clicks from the homepage that were required to find information about a service. dewey found library services navigation | rennick 16 https://doi.org/10.6017/ital.v38i1.10844 inconsistent use of terminology used to describe library services from one site to another. dewey posited that extensive use of library jargon could, in a sense, hide links from users. the overall conclusion was that the websites contained “too much information poorly placed.” a study of an academic library website by mcgillis and toms also found that participants struggled with terminology when attempting to locate services.10 the website reflected “traditional library structures” instead of using categories that were meaningful to users. the decision on where to place library services on a website is an important step in the design process. as part of their proposal to establish a benchmarking program for academic library websites, hightower, shih, and tilghman created classifications for the web pages they studied.11 library services were assigned to the “directional” category instead of representing a separate category. vaughan described a history of changes to an academic website that took place from 1996–2000.12 an interesting change was that, after multiple redesigns, the web designers combined two categories into a single “library services” category in order to simplify top level navigation on the home page. comeaux studied thirty-seven academic library websites to see how design elements evolved between 2012 and 2015.13 a portion of the study compiled terms used as navigation labels. the term “about” was the most common navigation label followed by “services” as the second most common. use of the term “services” as a main navigation label increased in popularity from 2012 to 2015. several researchers suggest organizing library services into web pages or portals that target different audiences. gullikson et al. studied usability issues related to the information architecture of an academic website and discovered that study participants followed different paths in their attempts to locate service information on the site.14 some users found items easily while others were unsuccessful. menu labels were not universally understood. the researchers identified a need for multiple access points to information in order to accommodate different mental models. they suggested employing multiple information organizational schemes, such as categorizing links by function, frequency of use, and target user group. adams and cassner analyzed the websites of arl libraries to see how services for distance education students and faculty were presented.15 they recommend strategies for helping distance students navigate the website, including maintaining a web page designed specifically for distance students that avoided jargon and clearly described services. detlor and lewis envisioned academic library websites as “sophisticated guidance systems which support users across a wide spectrum of information seeking behaviors—from goal-directed search to wayward browsing.”16 they reviewed arl library websites to see which important features were present or absent. their coding methodology was adopted by gardner, juricek, and xu in their study of how library web pages can meet the needs of campus faculty.17 liu proposed a conceptual model for an improved academic library website that would be organized into portals designed for specific user groups, such as undergraduates, faculty, or visitors.18 some of the arl websites studied by the researcher already implemented portals by user group. a more recent approach for locating library services has been to include website search results when using the single search from the homepage. for example, the north carolina state libraries website includes library-wide site search results when using the single search.19 the wayne state university libraries single search displays results from a university-wide site search.20 information technology and libraries | march 2019 17 an influential report produced by andrew pace provides practical advice for designing library websites.21 in the report, pace described the library services that should be included on a site and stressed that website design affects the discoverability and delivery of these services: “whether requiring minimal maintenance or constant upkeep, the extensibility of the design and flexibility of a site’s architecture ultimately saves the library time, money, hassle, and user frustration.”22 the web application described in this article aims to achieve these goals in terms of service discoverability and website maintainability. a services web application in an effort to tackle the challenges of services navigation and maintenance, the brigham young university library developed a web application for organizing services that allows multiple routes to service information. the application, known internally as “services,” was built using django, an open-source python web framework. the application incorporates a comprehensive list of library services and a map of service relationships. each service is assigned one or more categories, locations, and service areas within the application: • categories and subcategories—broad groupings of services (e.g., research help, for faculty, printing and copying) • locations—physical or virtual places within the library where services can be found (e.g., help desks, rooms) • service areas— library departments or other organizational units that offer services (e.g., humanities, special collections) services can have multiple categories, locations, and service areas and some service areas have multiple locations within the library (see figure 1). service information can also include links to related services. these links facilitate the serendipitous discovery of additional services (see figure 2). service information is stored in a relational database that joins connected entities together. an html template is used to format service information from the database in order to generate web pages for each of the services. maintaining the data in this manner ensures that changes made to service information in the database flow through to all of the associated web pages. adding or modifying entries automatically triggers the generation of new html for only the impacted services. generating static content by using triggers keeps the web pages up-to-date without the performance hit of real-time dynamic page generation. library services navigation | rennick 18 https://doi.org/10.6017/ital.v38i1.10844 figure 1. sample map illustrating relationships between services (on the left side) and service area locations (on the right side). information technology and libraries | march 2019 19 figure 2. sample map of how related service web pages are linked. library services navigation | rennick 20 https://doi.org/10.6017/ital.v38i1.10844 user scenarios the following examples of navigation paths typify how the web application can help users locate services. in each case there are multiple alternative paths that could be followed to find the same information. scenario 1. a student is looking for a computer that has music notation software installed. clicking the “services” link on the library homepage leads to a summary of library services. the student clicks the “public computers” link found under the “featured services” heading and is presented with detailed information about the computers. in the bullet points listed in the “overview” section there is a link to “see the list of software available on these computers.” following this link the student is able to learn that the desired software is available in the library’s music and dance media lab. scenario 2. while visiting a web page for the faculty delivery service, a professor notices a link to the category “for faculty.” following the link leads to a page that highlights some of the library services provided exclusively to campus faculty. the professor clicks the link “faculty expedited book orders” and is taken to a web page that describes the service and provides an online form for requesting a book. scenario 3. a student would like to borrow a camera for a class project. entering “digital cameras” into the main search box on the library homepage produces a link to “digital cameras (dslr)” listed under the “library services” heading at the top of the search results. following the link leads to a web page with information about the library’s digital camera offerings. the web page provides links to related services, including the library’s video production studio. the student decides to reserve the studio instead of checking out a camera. anatomy of a services web page each service web page is divided into sections to help users quickly find the type of information they seek. each section represents an information module with a specific purpose and an identifying design; the sections are color coded and displayed in a consistent order on each page. this helps users to find the same kind of information in the same place on every service page. major sections include: • title • description • keywords • hours • location • contact • overview • call to action • frequently asked questions • additional resources • related services • categories information technology and libraries | march 2019 21 a few of the sections require an explanation. the hours, location, and contact sections are links located directly below the title and description. clicking these links displays the section content. the overview section is intended to provide brief bullet points near the top of the web page so that users can quickly scan the most important information about the service. the call to action section follows these bullet points and contains one or more links to web applications that facilitate use of the service. examples of calls to action include: • place a hold • reserve a group study room • register for an advanced writing class • submit an interlibrary loan request most of the sections are optional since not all sections apply to every service. the services web pages can also include raw html that is embedded in a section in order to provide unique formatting for those services that do not neatly fit the standard layout. for example, the public computers page includes a section that displays the current availability of computers for each floor of the library. the look and feel of services web pages can be extended to other pages on the library website. library departments have web pages that provide information about personnel, mission, location, and services offered. some of these pages have been converted to a format that resembles the services layout in an effort to add cohesiveness to the library website. the department pages have sections similar to services pages such as hours, location, contact information, and an overview with bullet points. the pages can automatically display links to all of the services available in the department. because department pages are part of the services application and are connected to services with a relational database, changes to service information remains in sync across the entire website. this helps alleviate the problem of out-of-date department web pages. searching for services services can be located by submitting a query in a search box or by following links found on the main services web page. the services search engine matches words from the query with words found in a service name or associated tags. each service is tagged with keywords, phrases, or synonyms to increase the likelihood of successful searching. users may not be familiar with library jargon and will search for services using a variety of terms. it is impossible to name library services in a way that is understood by everyone, especially since academic library services target both students and faculty. a study on library services and user-centered language found that: “the choices of the graduate students did not always mirror those of the faculty. this highlights the inherent challenge of marketing services—the target audiences for the same service can have very different opinions and preferences.”23 services can have multi-word phrases assigned in addition to individual keywords. for example, the data management service has the following synonyms assigned: data curation, data management plan, and dmp. new keywords and phrases can be identified by reviewing search queries in the system log files and by conducting usability studies. library services navigation | rennick 22 https://doi.org/10.6017/ital.v38i1.10844 figure 3. the interlibrary loan service web page. information technology and libraries | march 2019 23 in addition to using a search box on the services web pages, users can search for services using the single search box on the library’s homepage. the single search box returns a link to matching services as part of search results when the search engine recognizes services keywords in a query. the services application has an api that makes keywords and other service information available to the single search box application. figure 4. search for a service from the single search box on the library’s homepage. figure 5. json results from the services api. to facilitate browsing, services are organized into three groups on the services web page: featured services, categories, and service areas. the featured services group highlights the most commonly sought-after services. categories are organized by the type of service or the target audience. the service areas group directs users to services available in library departments or units. the services web page does not list every service but instead directs users to web pages based on categories or service areas that list individual services. the services search feature can also include links to non-services. for example, library policies are not services yet users occasionally search for them on the services page (the library website posts {"status": 200, "results": [{"url": "https://lib.byu.edu/services/datamanagement/", "type": "service", "name": "data management", "slug": "datamanagement", "description": "through our institutional repository scholarsarchive, faculty can store research data. this is particularly useful for faculty who must develop data management plans for research projects funded by grants.", "keywords": ["data curation", "dmp", "data management plan", "data storage", "open access"]}], "total": 1, "query": "dmp"} library services navigation | rennick 24 https://doi.org/10.6017/ital.v38i1.10844 policy documents on the about page). in order to minimize user frustration with searching, links to non-services are included in search results so that users can be redirected to the desired pages. to help with optimization for external search engines such as google, each services page has a user-friendly url that clearly identifies the service. for example, the 3d printer service has the url https://lib.byu.edu/services/3d-printers/. each web page also includes the service name in an embedded html title tag. conclusion adopting a broad view of what represents a service has altered the library’s approach to the information architecture of the website. the services web application offers several innovations for improving library service discoverability and maintenance including: • standardized organization of service information • attaching keywords/aliases to service descriptions • an api for integration with the single search box on the homepage • links to related services • generation of web pages from a relational database usability tests were conducted throughout the development of the services application. follow-up assessments are planned for the future in order to verify that the application works as expected and to identify potential adjustments to the design. the services application shows promise as an effective tool for facilitating the discovery of services and increasing the reliability and uniformity of service information. acknowledgements the author gratefully acknowledges the contributions of grant zabriskie for the original concept and design of the services application and ben crowder for the implementation. references 1 cory lown, tito sierra, and josh boyer, “how users search the library from a single search box,” college & research libraries 74, no. 3 (may 2013): 227-41,

preservation process that leads to creating a well-organized web archive. a number of research articles are studied about web preservation projects and web archives, and designed a step-by-step systematic approach for web preservation. the proposed comprehensive web preservation process describes and combines strengths of different techniques observed during the study for preserving digital web contents into a digital web archive. for each web preservation step, different approaches and possible implementation techniques have been identified that can be adopted in digital archiving. the potential value of the proposed model is to guide the archivist, related personnel, and organizations to effectively preserved their intellectual digital contents for future use. moreover, the model can help to initiate a web preservation process and create a wellorganized web archive to efficiently manage the archived web contents. a section briefly describes the implementation of the proposed approach in a digital news stories preservation framework for archiving news published online from different sources. introduction the amount of information generated by institutions is increasing with the passage of time. one of the mediums that uses this information is the world wide web (www). the www has become a tool to share information quickly with everyone regardless of their physical location. the number of web pages is vast. google and bing each index approximately 4.8 billion.1 though the www is a rapidly growing source of information, it is fragile in nature. according to the available statistics, 80 percent of pages become unavailable after one year and 13 percent of links (mostly web references) in scholarly articles are broken after 27 months.2 moreover, 11 percent of posts and comments on websites for various purposes are lost within a year. according to another study conducted on 10 million web pages collected from the internet archive in 2001, the average survival rate of web pages is 1,132.1 days with a standard deviation of 903.5 days. 90.6 percent pages of those web pages are inaccessible today.3 the information fragility causes this valuable scholarly, cultural, and scientific information to vanish and become inaccessible to future generations. in recent years, it was realized that the lifespan of digital objects is very short, and rapid technological changes make it more difficult to access these objects. therefore, there is a need to preserve the information available on the www. digital preservation is performed using the primary methods of emulation and migration, in which emulation provides the preserved digital objects in their original format while migration provide objects in a different format.4 in the last systematic approach towards web preservation | khan and ur rahman 72 https://doi.org/10.6017/ital.v38i1.10181 two decades, a number of institutions worldwide, such as national and international libraries, universities, and companies started to preserve their web resources (resources found at a web server, i.e., web contents and web structure). the first web archive was initiated in 1996 by brewster kahle, named the internet archive, and it holds more than 30 petabytes data, which includes 279 billion web pages, 11 million books and texts, and 8 million other digital objects such as audio, video, image files, etc. more than seventy web archive initiatives were started in 33 countries since 1996, which shows the importance of web preservation projects and preservation of web contents. this information era encourages librarians, archivists, and researchers to preserve the information available online for upcoming generations. while digital resources may not replace the information available in physical form, the digital version of these information resources improves access to the available information.5 there are different aspects of the preservation process and web archiving, e.g., digital objects’ ingestion to the archive during preservation process, digital object’s format and storage, archival management, administrative issues, access and security to the archive, and preservation planning. these aspects need to be understood for effective web preservation and will help in addressing the challenges that occur during the preservation process. the reference model for open archival information system (oais) is an attempt to provide a high-level framework for the development and comparison of digital archives. in web preservation, a challenging task is to identify the starting point of the preservation process and to effectively complete the process which help to proceed further to the other activities. therefore, the complicated nature of the web and the complex structure of the web contents make the preservation of the web content even more difficult. the oais reference model helps in achieving the goals of a preservation task in a step-by-step manner. the stakeholders are identified, i.e., producer, management, and consumer, and the packages, i.e., submission information package (sip), archival information package (aip) and dissemination information package (dip), which need to be processed, are clearly defined.6 this study aims to design a step-by-step systematic approach for web preservation that helps to understand preservation or archival activities’ challenges, especially those that relate to digital information objects at various steps of the preservation process. the systematic approach may lead to an easy way to analyze, design, implement, and evaluate the archive with clarity and different options for an effective preservation process and archival development. an effective preservation process is one that leads to a well-organized, easily managed web archive and accomplishes designated community requirements. this approach may help to address the challenges and risks that confront archivists and analysts during preservation activities. step-by-step systematic approach digital preservation is “the set of processes and activities that ensure long-term, sustained storage of, access to and interpretation of digital information.”7 the growth and decline rates of www content and the importance of the information presented on the web make it a key candidate for preservation. web preservation confronts a number of challenges due to its complex structure, a variety of available formats, and the type of information (purpose) it provides. the overall layout of the web varies domain to domain based on the type of information and its presentation. the websites can be categorized based on two things. first, the type of information (i.e., the web information technology and libraries | march 2019 73 contents) and second, the way this information presented (i.e., the layout or structure of the web page. examples include educational, personal, news, e-commerce, and social networking websites, which vary a lot in their contents and structure. the variations in the overall layout make it difficult to preserve different web contents in a single web archive. the web preservation activities are summarized in figure 1. the following sections explain the web preservation activities and possible implementation in proposed systematic approach. defining the scope of the web archive the www provides an opportunity to share information using various services, such as blogs, social networking websites, e-commerce, wikis, and e-libraries. these websites provide information on a variety of topics and address different communities based on their interest and needs. there are many differences in the way the information is handled and presented on the www. in addition, the overall layout of the web changes from one domain to another domain.8 therefore, it is not practically feasible to develop a single system to preserve all types of websites for the long term. so, before starting to preserve the web, one (the archivist) should define the scope of the web to be archived. the archive will be either a site-centric, topic-centric, or domaincentric archive.9 site-centric archive a site-centric archive focuses on a particular website for preservation. these types of archives are mostly initiated by the website creator or owner. the site-centric web archives allow access to the old versions of the website. topic-centric archive topic-centric archives are created to preserve information on a particular topic published on the web for future use. for scientific verification, researchers need to refer to the available information while it is difficult to ensure access to these contents due to the ephemeral nature of the web. a number of topic-centric archive projects have been performed including the archipol archive of dutch political websites,10 the digital archive for chinese studies (dachs) archive2,11 minerva by the library of congress,12 and the french elections web archive for archiving the websites related to the french elections.13 domain-centric archive the word “domain” refers to a location, network, or web extension. a domain-centric archive covers websites published with a specific domain name dns, using either a top-level domain (tld), e.g., .com, .edu, or .org, or a second-level domain (sld), e.g., .edu.pk or .edu.fr. an advantage of domain-centric archiving is that it can be created by automatically detecting specific websites. several projects have a domain-centric scope, e.g., the portuguese web archive (pwa) national websites,14 the kulturarw, a swedish royal library web archive collection of.se and .com domain websites,15 and the uk government web archive collection of uk government websites, e.g., .gov.uk domain websites. understanding the web structure after defining the scope of the intended web archive, the archivist will have a better understanding of the interest and expected queries of the intended community based on the resources available or the information provided by the selected domain. the focus in this step is to understand the type of information (contents) provided by the selected domain and how the information has been presented. the web can be understood by two dimensions. the first systematic approach towards web preservation | khan and ur rahman 74 https://doi.org/10.6017/ital.v38i1.10181 figure 1. systematic approach for web preservation process. information technology and libraries | march 2019 75 considers the web as a medium that communicates contents using various protocols, i.e., http, and the second considers the web as a content container, which further presents the contents to the viewers and not simply contents, e.g. the underlying technology used to display the contents.16 the preservation team should understand such parameters as the technical issues, the future technologies, and the expected inclusion of other related content. identify the web resources the archivist should understand the contents and the representation of the contents of the selected domain, e.g., blogs, social networking websites, institutional websites, educational institutional websites, newspaper websites, or entertainment websites. all of these websites provide different information and address individual communities that have distinct information needs. a web page is the combination of two things, i.e., web contents and web structure.17 the resources which can be preserved are as follows. web contents web contents or web information can be categorized into the following categories: • textual contents (plain text): this category describes textual information that appears on a web page. it does not include links, behaviors, and presentation stylesheets. • visual contents (images): these contents are the visual forms of information or are a complementary material to the information provided in the textual form. • multimedia contents: as another form of information, multimedia contents mainly include audio and video. it may also include animation or even text as a part of a video or a combination of text, audio, and video. web structure web structure can be categorized in the following categories: • appearance (web layout or presentation): this category indicates the overall layout or presentation of a web page. the look and feel of a web page (representation of the contents) are important, which is maintained with different technologies, e.g., html or stylesheets, etc. • behavior (code navigations): categorized by link navigations, these can be within a website or to other websites, external document links or dynamic and animated features, such as live feed, comments, tagging, or bookmarking. identify designated community the archivist should identify the designated community of the intended web archive, their functional requirements and expected queries by analyzing them carefully. the designated community means the potential users, such as those who can access the archived web contents for different purposes, i.e., accessing old information that is not available in normal circumstances or referring to an old news article which is not bookmarked properly or retrieving relevant news articles published long ago, etc. prioritize the web resources after a comprehensive assessment of the resources of the selected domain and the identification of potential users’ requirements and expected queries, the archivist should prioritize the web systematic approach towards web preservation | khan and ur rahman 76 https://doi.org/10.6017/ital.v38i1.10181 resources. the complexity of web resources and their representation cause complications in the digital preservation process. generally, it may be undesirable or unviable to preserve all web resources; therefore, it is worthwhile to designate the web resources for preservation. the priority should be assigned on the basis of two things: first, the potential reuse of the resource and second, the frequency with which the resource will be accessed. the resources with no value, little value, or those managed elsewhere can be excluded. for prioritization of resources, the moscow method can be applied.18 the acronym moscow can be elaborated as: m must have, the resource must be preserved or resources that must be a part of the archive and preserved. for example, in the digital news story archive (dnsa), the textual news story must be preserved in the archive because the preservation emphasis is on a textual news story.19 online news contains textual news stories, and many news stories contain associated images, and a fraction of news stories contain associated audio-video contents. s should have, the resource should be preserved if at all possible. almost all the news stories have associated images; a few news stories have associated audio and video that complement it and should be preserved as a part of the news story in the web archive. c could have, the resource could be preserved if it does not affect anything else or is nice to have. the web structure in dnsa depends on the resources to be used for the preservation of news stories; the layout of the newspaper website could (c) be a part of the preservation process if it does not affect anything, e.g., storage capacity and system efficiency. w won’t have, the resource would not be included. archiving multiple versions of the layout or structure of the online newspaper are not worthwhile and hence would not (w) be preserved. the prioritization of these resources is very important in the context of web preservation planning because it does not waste time and energy, and it is the best way to handle users’ requirements and fulfill their expected queries. how to capture the resource(s) the selection of a feasible capturing technique depends on: first, the resources to be captured and second, the capturing task frequency. there are three web resources capturing techniques, i.e., by browser, web crawler, and authoring system. each capturing technique has associated advantages and disadvantages.7 web capturing using browsers the intended web content can be captured using browsers after a web page is rendered when the http transaction occurs. this technique is also referred to as a snapshot or post-rendering technique. the method captures those things which are visible to the users; the behavior and other attributes remain invisible. capturing static contents is one of the disadvantages of web capturing by the browser approach, this approach generally preserved contents in the form of images. it is best for well-organized websites, and commercial tools are available for capturing the web. the following are well-known tools to capture web using browsers. webcapture (https://web-capture.net/) is a free online web-capturing service. it is a fast web page snapshot tool, which can grab web pages in seven different formats, i.e. jpeg, tiff, png, bmp information technology and libraries | march 2019 77 image formats, pdf, svg, and postscript files of high quality. it also allows downloading the intended format in a zip file and is suitable for long vertical web pages with no distortion in layout. a.nnotate (http://a.nnotate.com/), is an online annotating web snapshot tool to keep track of information gathered from the web efficiently and easily. it allows adding tags and notes to the snapshot and building a personal index of web pages as document index. the annotation feature can be used for multiple purposes, for example, compiling an annotated library of objects for organization, sharing commented web pages, product comparison, etc. snagit (https://www.techsmith.com/screen-capture.html) is a well-known snapshot tool for capturing screens with built-in advanced image editing features and screen recording. snagit is a commercial and advanced screen capture tool that can capture web pages with images, linked files, source code, and the url of the web page. acrobat webcapture (file > create > pdf from web page...) creates a tagged pdf file from the web page that a user visits while the adobe pdf toolbar is used for the entire website.20 the capture by a browser technique has the following advantages: • by this technique, the archivist can capture only the displayed contents, and it is an advantage if you need to preserve the displayed contents only. • it is a relatively simple technique for well-organized websites. • commercial tools exist for web capturing using browsers. in addition, the disadvantages are the following: • capturing displayed contents only is a disadvantage if the focus is not on only displayed contents. • it results in frozen contents and treats contents as if they are publications. • it loses the web structure, such as appearance, behavior, and other attributes of the web page. web capturing using an authoring system/server the authoring system capturing technique is used for web harvesting directly from the website hosting server. all the contents, e.g., textual information, images, and source code, are collected from the source web server. the authoring system allows the archivist to preserve the different versions of the website. the authoring system depends on the infrastructure of the content management system and is not a good choice for external resources. the system is best for an owned web server and works well for limited internal purposes. the web curator tool (http://webcurator.sourceforge.net/), pandas (an old british library harvesting tool), and netarchivesuite (https://sbforge.org/display/nas/netarchivesuite) are known tools use for planning and scheduling web harvesting. they can be used by non-technical personnel for both selection and harvesting web content selection policies. these web archiving tools were developed in a collaboration of the national library of new zealand and the british library and are used for the uk web archive (http://www.ariadne.ac.uk/issue50/beresford/). the tools can interface with web crawlers, such as heritrix (https://sourceforge.net/projects/archivecrawler/). authoring systems are also referred to as workflow systems or curatorial tools. systematic approach towards web preservation | khan and ur rahman 78 https://doi.org/10.6017/ital.v38i1.10181 the authoring system has the following advantages: • it is best for web harvesting, which captures everything available. • it is easy to perform, if you have proper access permission or you own the server or system to access for capturing the resources. • it works in short to medium term resources and feasible for internal access within organizations. the disadvantages of web capturing using the authoring system are: • it captures all available raw information, not only presentations. • it may be too reliant on the authoring infrastructure or the content management system. • it is not feasible for large term resources, or for external access from outside organization. web capturing using web crawlers web crawlers are perhaps the mostly used technique for capturing web contents in systematic and automated manner.21 crawler development needs the expertise and experience of different tools, i.e. positive and negative of technologies, and the viability of a tool in a specific scenario. the main advantage of crawlers is that they extract embedded content. heritrix, httrack, wget, and deeparc are common examples of web crawlers. heritrix (https://github.com/internetarchive/heritrix3/wiki) is developed in java, an open source and freely available web crawler, and it was developed by internet archive. heritrix is one of the widely used extensible and web-scale web crawlers in web preservation projects. initially, the heritrix was developed for specific purpose crawling of specific websites and now a resourceful or customize web crawler for archiving the web. httrack (https://www.httrack.com/) is a freely available configurable browser utility. httrack crawls html, images, and other files from a server to a local directory and allows offline viewing of the website. the httrack crawler downloads a complete website from the web server to a local computer system and makes it available for offline for viewing with all related link-structure and seems like the user is using it online. it also updates the archived websites at the local system from the server and resumes all the interrupted previous extractions. the httrack available for both windows and linux/unix operating systems. wget (http://www.gnu.org/software/wget/) is a freely available non-interactive command line tool that can easily be configured with other technologies and different scripts. it can capture files from the web using widely used ftp, ftps, http and https protocols, and support cookies as well. it also updates the archived websites and resumes all the interrupted extractions. wget is available for both microsoft windows and unix operating systems. the advantages of web crawling: • widely used in capturing techniques. • can capture specific content or everything. • avoids some of the accessing issues, such as: link rewriting and embedded external content from an archive or live. information technology and libraries | march 2019 79 disadvantages associated with web crawling: • much work is required, as well as tools or development expertise and experience, etc. • the web crawler does not have the right scope: sometimes, it does not capture everything that it should, and sometimes the crawler captures too much content. web content selection policy in the previous steps, the web resources are identified, prioritized based on requirements and expected queries of the designated community, and feasible capturing technique is identified based on capturing frequency. now, the contents need to be prepared and filtered for selection, and a feasible selection approach needs to be selected based on the contents. a web content selection policy helps to determine and clarify, which web contents are required to be captured based on the priorities, the purpose and the scope of web contents already defined.22 the decision of the selection policy comprises the description of the context, the intended users, the access mechanisms and the expected uses of the archive. the selection policy may comprise the selection process and selection approach. the selection process can be divided into subtasks which, in combination, provide a qualitative selection of web contents to a certain extent, i.e., preparation, discovery, and filtering, as shown in figure 2. the main objective of the preparation phase is to determine the targeted information space, the capture technique, capturing tools, extension categorization, granularity level, and the frequency of archiving activity. the best personnel who can provide help in preparation are the domain experts, regardless of the scope of the web archive. the domain experts may be the archivists, researchers, librarians, or any other authentic reference, i.e. a document or a research article. the tools defined in the preparation phase will help to discover intended information in the discovery phase, which can be divided into the following four categories: 1. hubs may be the global directories or topical directories, collection of sites or even a single web page with essential links related to a particular subject or topic. 2. search engines can facilitate discovery by defining a precise query or set of alternative queries related to a topic. the use of specialized search engines can significantly improve the results of discovering related information that can be greatly improved. 3. crawlers can be used to extract web contents such as textual information, images, audio, video and links. moreover, the overall layout of a web page or a whole website can also be extracted in a well-defined systematic manner. 4. external sources may be non-web sources that may be anything, such as printed material for mailing lists, which can be monitored by the selection team. the main objective of the discovery phase is to determine the source of information to be stored the archive. this determination can be achieved by two ways. first, a manually created entry point list is used to determine the list of entry points (usually links) for crawling the collection manually and updating the list during the crawl. there are two discovery methods, i.e., exogenous and endogenous. exogenous discovery is used in manual selection and mostly relies on exploitation of an entry point list for hubs, search engines, and on non-web documents. second, there is an automatically created entry point list to determine the list of entry points by extracting links automatically and obtaining an updated list every time during the crawl. endogenous discovery is systematic approach towards web preservation | khan and ur rahman 80 https://doi.org/10.6017/ital.v38i1.10181 used in automatic selection and relies on the link extraction using crawlers by exploring the entry point list. figure 2. selection process. the main objective of the filtering phase is to optimize and make concise the discovered web contents (discovery space). filtering is important in order to collect more specific web content and remove unwanted or duplicated content. usually, for preservation, an automatic filtering method is used; manual filtering is useful if the robots or automatic tools cannot interpret the web. the discovery and filter phase can be combined practically or logically. several evaluation axes can be used for the selection policy (e.g., quality, subject, genre, and publisher). in the literature, we have three known techniques for selecting web content. the selection approach can be either automatic or manual. manual content selection is very rare because it is labor intensive: it requires automatic tools for finding the content, and then manual review of that collection to identify the subset that should be captured. automatic selection policies are used frequently in web preservation projects for web collection, especially for web archives.23 the selection of the collection approach depends on the frequency with which the web content has been preserved in the archive. there are four different selection approaches for web content collection. unselective approach the unselective approach implies collecting everything possible; by specifically using this approach, the whole website and its related domains and subdomains are downloaded to the archive. it is also referred to as automatic harvesting or selection, bulk selection, and domain selection.24 the automatic approach is used in a situation where a web crawler usually performs the collection. for example, the collection of websites from a domain, i.e., .edu means all educational institution websites (at domain level) or the collection of all possible contents/pages from a website (harvesting at website level) by extracting the embedded links. a section of the data preservation community believes that technically it is a relatively cheaper, quicker collection approach and yields a comprehensive picture of the web as a whole. in contrast, its significant drawbacks are that it generates huge unsorted, duplicated, and potentially useless data, consuming too many resources. information technology and libraries | march 2019 81 the swedish royal library’s project kulturarw3 harvests websites at domain level, i.e., collecting websites from a .se domain which is a physically located website in sweden and one of the first projects to adopt this approach.25 usually, national-based web archive initiatives adopt the unselective approach, most notably nedlib, a helsinki university library harvester, and aola, an austrian online archive.26 selective approach the selective approach was adopted by the national library of australia (nla) in the pandas project in 1997. in this approach, a website is included for archiving based on certain predefined strategies and on the access and information provided by the archive. the library of congress’ project minerva and the british library project “britain on the web” are the other known projects that have adopted the selective approach. according to nla, the selected websites are archived based on nla guidelines after negotiation with the owners.27 the inclusion decision could be taken at one of the following levels: • website level: which websites should be included from a selected domain, e.g., to archive all educational websites from high level domain “.pk”. • web page level: which web pages should be included from a selected website, e.g., to archive the homepages of all educational websites. • web content level: which type of web contents should be preserved, e.g., to archive all the images from the homepages of educational websites. a selective approach is best if the numbers of websites to be archived are very large or the archiving process is targeting the entire www and wants to narrow down the scope by identifying the resources in which the archivists are more interested. this approach performs implicit or explicit assumptions about the web contents that are not to be selected for preservation. it may be very helpful to initiate a pilot preservation project, which identifies: what is possible? what can be managed? in addition, some tangible results may be obtained easily and quickly in order to enhance the scope of the project in a broader perspective. the selective approach may be based on a predefined criterion or based on an event. selective approach based on criteria involves selecting web resources based on various predefined sets of criteria. nla’s guidance characterizes the criteria-based selective approach as the “most narrowly defined method,” and described it as “thematic selection.” a simple or a complex content-selection criteria can be defined, which depends on the overall goal of preservation. for example, all resources owned by an organization, all resources of one genre, i.e., all programming blogs, resources contributed to a common subject, resources addressing a specific community within an institution, i.e., students or staff, all publications belonging to an individual organization or group of organizations, all resources that may benefit external users or an external user’s community, e.g., historians, or alumni. selective approach based on event involves selecting web resources or websites based on various time-based events. the archivists may focus on websites that address national or international important events, e.g., disasters, elections, and the football world cup, etc. eventbased websites have two characteristics: (1) very frequent updates and (2) website content is lost after a short time, e.g., a few weeks or a few months. for example, the start and end of a term or systematic approach towards web preservation | khan and ur rahman 82 https://doi.org/10.6017/ital.v38i1.10181 academic year, the duration of an activity, e.g., research project, appointment, or departure of a new senior official. deposit approach in the deposit collection approach, the information package is submitted by the administrator or owner of the website which includes a copy of the website with related files that can be accessed through different hyperlinks. the archival information package is applicable to the small collection (of a few websites), or the owner of the website can initiate the preservation project, e.g. a company can initiate a project for preserving their website. the deposit collection approach was adopted by the national archives and records administration (nara) for the collection of us federal agency websites in 2001 and by die deutsche bibliothek (ddb, http://deposit.ddb.de/) for the collection of dissertations and some online publications. new digital initiatives are heavily dependent on administrator or owner support and provide an easy way to deposit new content to the repository, e.g., in the macewan university’s institutional repository, the librarians leading the project tried to offer an easy and effective way to deposit their archival contents.28 combined approach there are advantages and disadvantages associated with each collection approach. the ongoing debate is which approach is best in a given situation. for example, the deposit approach should be an inexpensive agreement with the depositors. the emphasis is to use the combination of automatic harvesting and selective approaches as these two approaches are cheaper as compared to other selection approaches because a few staff personnel are required and cope with technological challenges. this initiative was taken by the bibliothque nationale de france (bnf) in 2006. the bnf automatically crawls information regarding the updated web pages and stores it in an xml-based “site delta” and uses page relevancy and importance, similar to how google ranks pages, to evaluate individual pages.29 the bnf used a selective approach for the deep web (that is, web pages or websites that are behind a password or are otherwise not generally accessible to search engines), referred to as “deposit track.” metadata identification cataloging is required to discover a specific item from the digital collection. an identifier or set of identifiers is required to retrieve a digital record in digital repositories or an archive. for digital documents, this catalog or registration or identifier is referred to as metadata.30 metadata are structured information concerning resources that describe, locate (discover or place), manage, easily retrieve (access) and use digital information resources. metadata are often referred to as “data about data” or “information about information”, but it may be more helpful and informative to describe these data as “descriptive and technical documentation.”31 metadata can be divided into the following three categories: 1. descriptive metadata describes a resource for discovery and identification purposes. it may consist of elements for a document such as title, author(s), abstract, and keywords, etc. 2. structural metadata describes how compound objects are put together, for example, how sections are ordered to form chapters. information technology and libraries | march 2019 83 3. administrative metadata imparts information to facilitate resource management, such as when and how a file was created, who can access the file, its type, and other technical information. administrative metadata is classified into two types: (1) rights management metadata addresses intellectual property rights and (2) preservation metadata contains information needed to archive and preserve a resource.32 due to new information technologies, digital repositories, especially web-based repositories, have grown rapidly over the last two decades. this interest prompts the digital libraries communities to devise metadata strategies to manage the immense amount of data stored in digital libraries.33 metadata play a vital role in the long-term preservation of digital objects and important to identify the metadata which may help to retrieve a specific object from the archive after preservation. according to duff et al., “the right metadata is the key to preserving digital objects.”34 there are hundreds of metadata standards developed over the years for different user environments, disciplines, and for different purposes; many of them are in their second, third, or nth edition.35 digital preservation and archiving requires metadata standards to trace and ensure its access to the digital objects. several of the common standards are briefly discussed below. dublin core metadata initiative (dcmi, http://dublincore.org/) was initiated at the 2nd world wide web conference in 1994 and was standardized by ansi/niso z39.85 in 2001 and iso 15386 in 2003.36 the main purpose of the dcmi was to define an element set for representing web resources; initially, thirteen core elements were defined which later increased to a fifteen-element set. the elements are optional, repeatable, can be followed in any order, and expressed in xml.37 metadata encoding and transmission standard (mets, http://www.loc.gov/standards/mets/) is an xml metadata standard intended to represent information of the complex digital objects. mets elements evolved from the early project making of america ii “moa2” in 2001, supported by the library of congress and sponsored by the digital library federation “dlf” and registered with national information standards organization “niso” in 2004. a mets document contains seven major sections in which each contains different aspects of metadata.38 metadata object description schema (mods, http://www.loc.gov/standards/mods/) was initiated by the marc21 maintenance agency at the library of congress in 2002. mods elements are richer then dcmi, simpler then marc21 bibliographic format and expressed in xml.39 the mods identified the widest facets or features of an object and presented nineteen high-level optional elements.40 visual resources association core strategies (vra core, http://www.loc.gov/standards/vracore/) was developed in 1996, and the current version 4.0 was released in 2007. the vra core is a widely used standard for art, libraries, and archives for such objects as paintings, drawings, sculpture, architecture, and photographs, as well as books and decorative and performance art.41 the vra core contains nineteen elements and nine sub-elements.42 preservation metadata implementation strategies (premis, http://www.loc.gov/standards/premis/) was developed in 2005, sponsored by the online computer library center (oclc) and the research libraries group (rlg), includes a data dictionary and some information about metadata. premis defined a set of five interactive core semantic units or entities and xml schema for endorsing digital preservation activities. it is not systematic approach towards web preservation | khan and ur rahman 84 https://doi.org/10.6017/ital.v38i1.10181 concerned with discovery and access but with common metadata, and for descriptive metadata, other standards (dublin core, mets or mods) need to be used. the premis data model contains intellectual entities (contents that can be described as a unit, e.g., books, articles, databases), objects (discrete units of information in digital form, which can be files, bitstreams, or any representation), agents (people, organization, or software), events (actions that involve an object and an agent known to the system) and rights (assertion of rights and permission).43 it is indisputable that good metadata improves access to the digital object in the digital repository. therefore, the creation and selection of appropriate metadata make the web archive accessible to the archive user. structure metadata helps to manage the archival collection internally, as well as the related services, but may not always help to discover the primary source of the digital object.44 currently, there are many semi-automated metadata generation tools. the use of these semiautomatic tools for generating metadata is crucial for the future, considering the operation’s complexity and cost of manual metadata origination.45 archival format the web archive initiatives select websites for archiving based on relevance of contents and the intended audience of the archived information. the size of the web archives varies significantly depending on their scope and the type of content they are preserving, e.g., web pages, pdf documents, images, audio, or video files.46 to preserve these contents, a web archive uses different storage formats containing metadata and utilizes data compression techniques. the internet archive defined the arc format (http://archive.org/web/researcher/arcfileformat.php), later used as a defacto standard. in 2009, the internet organization for standardization (iso) established the warc format (https://goo.gl/0rbwsn) as an official standard for web archiving. approximately 54 percent of web archive initiatives applied arc and warc formats for archiving. the use of standard formats helps the archivists to facilitate the creation of collaborative tools, such as search engines and ui utilities to efficiently manipulate the archived data.47 information dissemination mechanisms a well-defined preservation process can lead to a well-organized web archive that is easy to maintain and easy to retrieve a specific digital object from the collection using information dissemination techniques. poor search results are one of the main problems in information dissemination of web archives. the users of a web archive expend excessive time to retrieve intended documents or information to satisfy the user’s query. archivists are more concerned with “ofness,” “what collections are made up of,” although archive users are concerned with aboutness, “what collections are about.”48 to use the full potential of web archives a usable interface is needed to help the user to search the archive for specific digital object. full text and keyword search are the dominant ways to search the unstructured information repository, evidently observed from the online search engines. the sophistication of search results against user queries is based on the ranking tools.49 the access tools and techniques are getting the attention of researchers, and approximately 82 percent of european web archives concentrate on such tools, which makes these web archives easily accessible.50 the lucene full-text search engine and its extension nutchwax is widely used in web archiving. moreover, for the combination of semantic descriptions that already rely on or are implicit within their descriptive metadata, reasoning-based or semantic searching of the archival information technology and libraries | march 2019 85 collection can enable the system to produce novel possibilities for the archival content retrieval and browsing.51 even in the current era of digital archives, mobile services are adopted in digital libraries, e.g., access to e-books, libraries databases, catalogs, and text messaging are common mobile services offered in university libraries.52 in a massive repository, a user query retrieves millions of documents, which makes it difficult for users to identify the most relevant information. the ranking model estimates the results relevancy based on user’s queries using specified criteria to overcome this problem and sorts the results by placing the most relevant result at the top.53 there are a number of ranking models that exist in the literature, e.g., conventional ranking models, e.g., tf-idf, bm25f, temporal ranking models, e.g., pagerank, and learning to rank models, e.g., l2r. the findings of the systematic approach for web preservation are used to automate the process of the digital news-story preservation. the steps of the proposed model are carefully adopted to develop a tool that is able to add contextual information to the stories to be preserved. digital news stories preservation framework the advancement of web technologies and maturation of the internet attracts news readers to access news online that is provided by multiple sources and to obtain the desired information comprehensively. the amount of news published online has grown rapidly, and for an individual, it is cumbersome to browse through all online sources for relevant news articles. the news generation in the digital environment is no longer a periodic process with a fixed single output, such as printed newspapers. the news is instantly generated and updated online in a continuous fashion. however, because of different reasons, such as the short lifespan of digital information and the speed of generation of information, it has become vital to preserve digital news for the long term. digital preservation includes various actions to ensure that digital information remains accessible and usable, as long as they are considered important.54 libraries and archives preserve by carefully digitizing newspapers considering as a good source of knowing the history. many approaches have been developed to preserve digital information for the long term. the lifespan of news stories published online varies from one newspaper to another, i.e., from one day to a month. however, a newspaper may be backed up and archived by the news publisher or national archives; in the future, it will be difficult to access particular information published in various newspapers regarding the same news story. the issues become even more complicated if a story is to be tracked through an archive of many newspapers, which requires different access technologies. the digital news story preservation (dnsp) framework was introduced to preserve digital news articles published online from multiple sources.55 the dnsp framework is planned based on adopting the proposed step-by-step systematic approach for web preservation to develop a wellorganized web archive. initially, the main objectives defined for the dnsp framework are: • to initiate a well-organized national level digital news archive of multiple news sources. • to normalize news articles during preservation to a common format for future use. • to extract explicit and implicit metadata, which would be helpful in ingesting stories to the archive and browsing through the archive in the future. • to introduce content-based similarity measures to link digital news articles during preservation. systematic approach towards web preservation | khan and ur rahman 86 https://doi.org/10.6017/ital.v38i1.10181 the digital news story extractor (dnse) is a tool developed to facilitate the extraction of news stories from the online newspapers and to migrate to a normalized format for preservation. the normalized format also includes a step to add metadata in the digital news stories archive (dnsa) for future use.56 to facilitate the accessibility of news articles preserved from multiple sources, some mechanisms need to be adopted for linking the archived digital news articles. an effective term-based approach “common ratio measure for stories (crms)” for linking digital news articles in dnsa is introduced that links similar news articles during the preservation process.57 the approach is empirically analyzed, and the results of the proposed approach are compared to get conclusive arguments. the initial results computed automatically using a common ratio measure for stories are encouraging and are compared with the similarity of news articles based on human judgment. the results are generalized by defining a threshold value based on multiple experimental results using the proposed approach. currently, there is ongoing work to extend the scope of dnsa to dual languages, i.e., urdu and english, as well as content-based similarity measures to link news articles published in urduenglish. moreover, research is underway to develop tools for exploiting the linkage created among stories during the preservation process for search and retrieval tasks. summary effective strategic planning is critical in creating web archives; hence, it requires a wellunderstood and a well-planned preservation process. the process should result in a wellorganized web archive that includes not only the content to be preserved but also the contextual information required to interpret the content. the study attempts to answer many questions by guiding the archivists and related personnel, such as: how to lead the web preservation process effectively? how to initiate the preservation process? how to proceed through different steps? what are the possible techniques that may help to create a well-organized web archive? how can the archived information can be used to its greatest potential? to answer these questions, the study resulted in an appropriate step-by-step process for web preservation and a well-organized web archive. the targeted goal of each step is identified by researching the existing approaches that can be adopted. the possible techniques for those approaches are discussed in detail for each step. references 1 “world wide web size,” the size of the world wide web, visited on jan 31, 2019,

information technology and libraries | september 2010 lita committees and interest groups are being asked to step up to the table and develop action plans to implement the strategies the lita membership have identified as crucial to the association’s ongoing success. members of the board are liaisons to each of the committees, and there is a board liaison to the interest groups. these individuals will work with committee chairs, interest group chairs, and the membership to implement lita’s plan for the future. the committee and interest group chairs are being asked to contribute those actions plans by the 2011 ala midwinter meeting. they will be compiled and made available to all lita and ala members for their use through the lita website (http://lita.org) and ala connect (http://connect.ala.org). what is in it for you? lita is known for its leadership opportunities, continuing education, training, publications, expertise in standards and information policy, and knowledge and understanding of current and cuttingedge technologies. lita provides you with opportunities to develop those leadership skills that you can use in your job and lifelong career. the skills working within a group of individuals to implement a program, influence standards and policy, collaborate with other ala divisions, and publish can be taken home to your library. your participation documents your value as an employee and your commitment to lifelong learning. in today’s work environment, employers look for staff with proven skills who have contributed to the good of the organization and the profession. lita needs your participation in developing and implementing continuing education programs, publishing articles and books, and illustrating by your actions why others want to join the association. how can you do that? volunteer for a committee, help develop a continuing education program, write an article, write a book, role model for others with your lita participation, and recruit. what does your association gain? a solid structure to support its members in accomplishing the mission, vision, and strategic plan they identified as core for years to come. look for opportunities to participate and develop those skills. we will be working with committee and interest group chairs to develop meeting management tool kits over the next year, create opportunities to participate virtually, identify emerging leaders of all types, collaborate with other divisions, and provide input on national information policy and standards through ala’s office for information technology policy and other similar organizations. if you want to be involved, be sure to let lita committee and interest group chairs, the board, and your elected officers know. c loud computing. web 3.0 or the semantic web. google editions. books in copyright and books out of copyright. born digital. digitized material. the reduction of stanford university’s engineering library book collection by 85 percent. the publishing paradigm most of us know, and have taken for granted, has shifted. online databases came and we managed them. then cd-roms showed up and mostly went away. and, along came the internet, which we helped implement, use, and now depend on. how we deal with the current shifts happening in information and technology during the next five to ten years will say a great deal about how the library and information community reinvents itself for its role in the twenty-first century. this shift is different, and it will create both opportunities and challenges for everyone, including those who manage information and those who use it. as a reflection of the shifts in the information arena, lita is facing its own challenges as an association. it has had a long and productive role in the american library association (ala) dating back to 1966. the talent among the association members is amazing, solid, and a tribute to the individuals who belong to and participate in lita. lita’s members are leaders to the core and recognized as standouts within ala as they push the edge of what information management means, and can mean. for the past three years, lita members, the board, and the executive committee have been working on a strategic plan for lita. that process has been described in michelle frisque’s “president’s message” (ital v. 29, no. 2) and elsewhere. the plan was approved at the 2010 ala annual conference in washington, d.c. a plan is not cast in concrete. it is a dynamic, living document that provides the fabric that drives the association. why is this process important now more than ever? we are all dealing with the current recession. libraries are retrenching. people face challenges participating in the library field on various levels. the big information players on the national and international level are changing the playing field. as membership, each of us has an opportunity to affect the future of information and technology locally, nationally, and internationally. this plan is intended to ensure lita’s role as a “go to” place for people in the library, information, and technology fields well into the twenty-first century. karen j. starr (kstarr@nevadaculture.org) is lita president 2010–11 and assistant administrator for library and development services, nevada state library and archives, carson city. karen j. starrpresident’s message: moving forward 198 information technology and libraries | december 2011 yan hantutorial articles: one was to make a case for using the cloud;4 while the other provided more details of moving a library’s it infrastructure (ils, website, and digital library systems) to a cloud along with discussing motivation, results, and evaluation in three areas (quality and stability, impact on library services, and cost).5 on the cost discussion, mitchell mentioned the difficulty of calculating technology total cost of ownership (tco) and cited two papers suggesting minimal cost savings. mitchell suggested the same but did not provide detailed cost information. in comparison, this paper has a detailed breakdown cost analysis along with different services, such as web applications and storage. mirsa and mondal proposed a suitability index and a return on investment (roi) model by taking into consideration impacts and real value.6 their suitability index and roi model is well thought but consider using the cloud for every aspect of all it operations as a whole. as a result, a company using this model will have the final conclusion of a “suitable,” or “may or may not be,” or “not suitable.” however, modular it operations and services (e.g., e-mail and storage) can be evaluated individually because these services can be easily upgraded or changed with minimal impacts to customers. i/o intensive services and storage intensive services have different resource requirements and thus the same evaluation criteria may not give an accurate picture of costs and benefits. for example, storing digital preservation files for libraries is a one-time data intensive operation. giving the above different nature of it operations and services, cloud computing may be suitable for some it operations but not for others. healy suggested that many companies did not have a complete financial analysis by missing staff retraining and system management. he listed the following areas for tco: hardware, software, recurring licensing and maintenance, bandwidth, a starting point for locating information for research; (2) buyer, the library as a purchaser of resources; and (3) archive, the library as a repository of resources. the 2009 survey indicates a gradual decline in their perception of the importance of “gateway,” no change in “archive,” growth in “buyer,” and increased importance for two new roles: “teaching support” and “research support.”1 to meet customers’ needs in these roles, libraries are innovating services, including catalogs and home websites (as “gateway” services), repository and digital library programs (as “archive,” “teaching support,” and “research support” services), and interlibrary loan (as a “buyer” and “research support” services). these services rely on stable and effective it infrastructure to operate. in the past, the growing needs of these web applications increased it expenditures and work complexity. more web applications, more storage, and more it support staff are weaved into centralized on-site it infrastructure along with huge investments in physical servers, networks, and buildings. however, decreasing budgets in libraries have had huge impact on all aspects of library operations and staffing. web applications running on local, managed servers might not be effective in technology nor efficient in cost. web applications utilizing cloud computing can be much more effective and efficient in some cases. literature review there are a growing number of articles related to cloud computing in libraries. chudnov described his personal experience of using cloud services amazon ec2 and s3 in an informal tone, costing him 50 cents.2 jordan discussed oclc’s strategies of building its next generation of services in cloud and provided a clear view of oclc’s future directions for us.3 mitchell wrote two cloud computing: case studies and total costs of ownership this paper consists of four major sections: the first section is a literature review of cloud computing and a cost model. the next section focuses on detailed overviews of cloud computing and its levels of services: saas, paas, and iaas. major cloud computing providers are introduced, including amazon web services (aws), microsoft azure, and google app engine. finally, case studies of implementing web applications on iaas and paas using aws, linode and google appengine are demonstrated. justifications of running on an iaas provider (aws) and running on a paas provider (google appengine) are described. the last section discusses costs and technology analysis comparing cloud computing with local managed storage and servers. the total costs of ownership (tco) of an aws small instance are significantly lower, but the tco of a typical 10tb space in amazon s3 are significantly higher. since amazon offers lower storage pricing for huge amounts of data, the tco might be lower. readers should do their own analysis on the tcos. a 2009 study from ithaka suggested that faculty perceive three traditional functions of a library: (1) gateway, the library as yan han

computing: case studies and total costs of ownership | han 199 fundamental computing resources so that they can deploy and run arbitrary software such as operating systems and applications.13 in this model, the providers only manage underlying physical cloud infrastructure (e.g. physical servers and network), and provides services via virtualization. the users have maximum control on the infrastructure as if they own underlying physical servers and network. leading providers of this model includes amazon, linode, rackspace, joyent, and ibm blue cloud. major cloud computing providers include amazon web services (aws), microsoft windows azure, and google appengine. aws is considered to be an iaas, paas, and saas provider, which offers a collection of multiple computing services through the internet, including a few well-known services such as amazon elastic compute cloud (ec2),14 amazon simple storage service (s3), and amazon simpledb. ec2 started as a public beta in 2006. it allows users to pay for computing resources as they use them. with scalable use of computing resources and attractive pricing models, ec2 is one of the biggest brand names in cloud computing. it offers different os options, including multiple linux distributions, opensolaris, and windows server. ec2 uses xen virtualization, each virtual machine is called an instance. an instance in ec2 has no persistent storage, and data stored will be lost if the instance is terminated. therefore it is typical to use ec2 along with amazon elastic block store (ebs) or s3, which provides persistent storage for ec2 instances. amazon claims that both ebs and s3 are highly available and reliable. a user can create, start, stop, and terminate server instances through multiple geographical locations for benefits of resource optimization and high availability. for example, a user can start an instance in northern virginia, a potential to transform the it industry and it services, shifting the way it infrastructure and hardware are designed, purchased, and managed. many experts have their own version of cloud computing, which was discussed before.9 the national institute of standards and technology defines cloud computing as “a model for enabling convenient, on-demand network access to a shared pool of configuration computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.”10 nist also gives its three service models layered based on computing infrastructure: ■■ software as a service (saas) allows users to use the cloud computing providers’ applications through a thin client interface such as a web browser.11 in the saas model, the cloud computing providers manage almost everything in the cloud infrastructure (e.g., physical servers, network, os, applications). it is directly targeted for general end users. the end users can directly run applications on the clouds and do not need install, upgrade, and backup applications and their work. typical saas products are google apps and salesforce sales crm. ■■ platform as a service (paas) allows users to deploy their own applications on the provider’s cloud infrastructure under the provider’s environment such as programming languages, libraries, and tools.12 in this model, the cloud computing providers manage everything except the application in the cloud infrastructure. paas is directly targeted for general software developers. they can develop, test, and run their codes on a paas platform. typical examples of this model includes google appengine, windows azure, and joyent. ■■ infrastructure as a service (iaas) allows users to manage processing, storage, networks, and other staffing allocation, monitoring, backup, failover, security audit and compliance, integration, training, and speed to implementation.7 the author published his first paper regarding cloud computing in 2010.8 since then, the author has implemented and has been managing multiple web applications and services using iaas and paas providers. several web applications of the university of arizona libraries (ual) have been migrated to the cloud. this paper focuses on enterprise-level applications and services, not individual-level cloud applications such as google docs. the purposes of this article are to ■■ define cloud computing and levels of services; ■■ introduce and compare major cloud computing providers; ■■ provide case studies of running two web applications (dspace and a home grown java application) utilizing cloud computing with justification; ■■ provide a comparison of tco of running web applications comparing a cloud computing provider with a local managed server; ■■ provide a comparison of tco of 10tb storage space comparing a cloud computing provider with local managed storage; and ■■ briefly discuss technology advantages of cloud computing. definition of cloud computing and levels of services cloud computing services and providers cloud computing is becoming popular in the it industry. over the past few years, the supply-and-demand of this new area has been seeing a huge increase of investment in infrastructure and has been drawing broader uses in the united states. the author believes that it has a 200 information technology and libraries | december 2011 16gb storage, 200gb transfer, and the cost is $19.95 per month.20 customers pay up front. open-source cloud computing software and private cloud cloud computing also goes to open source if any person or organization wants to set up their own clouds. eucalyptus is an open-source cloud computing system developed by the university of california at santa barbara. some of its eye-catching features include full compatibility with amazon ec2 public infrastructure and multiple hypervisors, which allows different virtual machines (e.g., xen, kvm, vsphere) to run on one platform.21 its open-source company, eucalyptus systems, provides technical supports to end users. building a cloud infrastructure on cloud(s) is also possible and might be desirable in certain situations. current linux distributions work with eucalyptus to provide private cloud services such ubuntu enterprise cloud and red hat’s deltacloud. some organizations have been setting up private clouds to utilize advantages of cloud computing. the azure allows non-windows applications to run on the platform. for example, apache web server can be run as a “worker role.”17 there also are a few small-to-medium size providers such as linode.18 table 1 lists major cloud computing providers. the cloud computing providers operate in two business models: variable (pay-for-your-usage) plans and fixed plans. variable plans allows customers to pay only for the resources actually consumed (e.g., instancehours, data transfer). aws offers a variable plan. google app engine works in a similar way. google app engine offers two interesting features: daily budgets and free quotas. a daily budget allows customers to control the amount of resources used every day. the free quota is currently set as 6.5 hours of cpu time per day, 1 gb data in and out per day, and 1gb of data storage.19 by the end of each month, customers receive a bill listing the number of running hours, the amount of storage used, the size of data transfers, and other add-on services. linode only offers a fixed plan. the charge is based on the amount of ram, data storage, and data transfer by assuming an instance is always running. for example, the smallest instance has 360mb ram, mirroring instance in ireland, and another mirroring instance in asia. amazon keeps increasing its offering by introducing new paas and saas services, such as simpledb, simple e-mail service, and e-commerce. google app engine is a paas provider offering a cloud platform for web applications in google’s data centers. it was released as a beta version in 2008 but is currently in a full service mode. appengine functions like a middle layer, which frees customers worrying about running oss, modules, and libraries. it currently supports python and java programming languages and related frameworks, and it is expected to support more languages in the future. google app engine uses bigtable with its gql (a sqllike language). bigtable15 is google’s proprietary database, used in multiple google applications such as google earth, google search, and app engine. the design of gql intentionally does not support “join” statement for multiple machine optimization.16 unlike aws, google appengine has a nice feature that allows customers a taste of the platform: it is free of charge up to a certain level of resource use. after that, fees are charged for additional cpu time, bandwidth and storage. windows azure also is a paas provider, which runs on microsoft data centers. it provides a new way to run applications and storing data in microsoft way. microsoft customers can install and run applications on microsoft cloud. customers are provided with two different instance types: web role instances and worker role instances. customers can use a “web role instance” to accept incoming http/https requests using asp.net, windows communication foundation (wcf) or another.net technology working with iis. a “worker role instance” is not associated with iis, but functions as a background job. the two instances can be combined to create desired web services. it is clear that windows table 1. list of major cloud computing providers

case study 2: japanese gif holding library finder application the author helped the north american coordinating council on japanese library resources (ncc) to develop and maintain a web service to identify japanese global ill framework (gif) libraries to facilitate interlibrary loan (ill) service. the application was developed in java using j2ee framework, and run in typical java servlet container such as tomcat. the application was initially operated in a small, locally managed server, and was migrated to linode and google appengine in may 2010. cloud computing provider selection and

on their cloud infrastructure. google appengine might be a better choice when applications run on normal os environments, because system administration tasks can be completed by paas providers, saving users’ time and resources. as a paas provider, google maintains its infrastructure environment such as os, programming languages, and tools. installing the application in google appengine can go through an eclipse plug-in or through command lines. in this case, the gif application is a simple system written in java without any database transactions. therefore google app engine’s proprietary gql database is not a barrier. however, users should be aware that google appengine has other unique features. for example, cloud computing provider selection and implementation a typical dspace instance requires java and related libraries, j2ee environment, and postgresql as database backend. three cloud computing providers have been evaluated: aws, linode, and google appengine. two instances were successfully installed and configured in aws and linode after a few days of testing. building a dspace instance on the cloud is the same process as running it on local except that it is much quicker to build, restart, rebuild, and backup. for example, an initial os installation in a traditional server will take a few hours compared to doing the same task that takes a few minutes using an iaas provider. installation on the aws ec2 and linode is almost the same except creating a login and setting up security policies. to log on to aws, command line tools using an x.509 certificate using public/private key are by default. a generated keypair is required to ssh an instance and no password ssh option is provided. in addition, appropriate “security groups” are required to set up to enable network protocols. in this case, protocols such as ssh and http along with typical port number 80 and 8080 must be enabled. activities such as manage instances, creating images, and setup security policies can be set up through aws web interface (see figure 1). steps and commands of running regular operations can be found in the appendix. in linode, using “root” to log on is allowed. users do not need to set network and security policies, as protocols and ports are already open. in system administration practice, running applications without enforcing security policies does present security risks to applications and systems. linode allows users to set up security policies. the author decided not to proceed with installation in google appengine because of its proprietary database gql. if implemented in google appengine, private cloud eases concerns in the public cloud such as security of data, control of data, and legal issues. for example, an institution can build its own cloud infrastructure using eucalyptus (or ubuntu cloud) with its own computing resources or simply using amazon aws. the private cloud computing service becomes customizable cloud computing resources which can be configured and reconfigured as needed. why is this valuable? in traditional computing approaches, servers, storage, and networking equipment are purchased, configured, and then used without significant changes for three to five years until lives end. in this case, some planning must be scheduled ahead of time thinking of computing resource needs in three to five years. it is certain that additional resources (e.g., ram, hard disks, cpu) will be reserved for future needs and are currently wasted. the private cloud reduces concerns regarding security and data control. however, one must still buy, build, and manage the private cloud, increasing tco and reducing the cost benefit. case studies: applications on the cloud case study 1: dspace implementation and analysis many libraries are running their institutional repositories at locally managed servers. ual has been running its repositories since 2004 as one of the earliest dspace adapters. one of the dspace instances was tested on the cloud in january 2010 after comparing costs and supports. later the author chose to run a production dspace in aws starting march 2010. the repository (http://www.afghan data.org/) currently holds 1,800 titles of digitized unique afghan materials. since then, several content and system updates have been applied. 202 information technology and libraries | december 2011 a good case for calculating the tco.25 in cases below, readers should be aware that there are the following assumptions: ■■ software, training, licensing, and maintenance costs are the same by assuming using on the same software environment on the local managed infrastructure and on the cloud. ■■ monitoring costs are the same based on the fact that monitoring software has to be hosted somewhere. ■■ bandwidth and network costs ignored. ■■ security audit and compliance ignored by assuming all data are open. the author runs an instance of 100gb in aws and a monthly bill of this node is around $40. in comparison, if running a local managed server, a physical server would have been purchased. in our case, a comparison of tco shows that the cloud computing model has a significant 50 percent cost saving, assuming a server life expectancy is five years. analysis and discussions cost analysis running applications on the cloud gives many technical advantages and results in significant cost savings over running them on local managed servers. in this section, the author presents detailed cost comparisons between virtual managed nodes in the cloud computing and local managed storage and servers in the traditional model. cost saving and low barriers to launch web services using the cloud is significant when considering easy start-up, scalability, and flexibility. one of the biggest advantages of the cloud computing lies in its on-demand, allowing users to start applications with minimal cost. the current cost of starting an instance on aws is 0.03 per hour if reserved. above the clouds: a berkeley view of cloud computing cites a comparison: “it costs $2.56 to rent $2 worth of cpu” and “costs are $6.00 when purchasing vs. $1.20–$1.50 per month on s3.”24 clearly healy made currently google appengine only allows users to have their codes running in python and java; it uses its own database query language gql. this creates an extra step for developers who are willing to migrate existing codes to google and existing sql queries have to be rewritten. in addition, other limitations with google app engine include allowing only a subset of the jre standard edition and users are unable to create new threads.22 the cost of running the application on google app engine is great, because google app engine offers free of charge up to its free quota. google identified 90 percent of applications were hosted free.23 this is a great paas resource for small web applications. applications on the cloud since 2009, the author has been running multiple web applications and services on multiple iaas and paas providers and has been very happy regarding services and overall costs. the running applications and services are listed in table 2.

social networking sites made possible through web 2.0 allow for unique user-generated tags called “searchable signatures.” these tags move beyond the descriptive and act as means for users to assert online individual and group identities. this paper presents a study of searchable signatures on the instagram application, demonstrating that these types of tags are valuable not only because they allow for both individuals and groups to engage in what social theorist axel honneth calls the “struggle for recognition,” but also because they provide contextual use data and sociohistorical information so important to the understanding of digital objects. methods for the gathering and display of searchable signatures in digital library environments are also explored. introduction a comparison of user-generated tags with metadata traditionally assigned to digital objects suggests that social network platforms provide an intersubjective space for what social theorist axel honneth has termed the “struggle for recognition.” 1 social network users, through the creation of identity-based tags—or what can be understood as “searchable signatures”—are able to assert and perform online selves and are thus able to demand, or struggle for, recognition within a larger social framework. baroncelli and freitas cogently argue that web 2.0, or the interactive online social arena, in fact functions as a “recognition market in which contemporary individuals . . . trade personal worth through displays and exchanges of . . . self-presentations.” 2 a comparison of a metadata schema used in yale university’s digital images database with usergenerated tags accompanying shared photographs on the social networking platform instagram demonstrates that searchable signatures are unique to social networking sites. as phenomena that allow for public presentations of disembodied selves, searchable signatures thus provide specific information about the context of the digital images with which they are associated. capturing context remains a challenge for those working with digital collections, but searchable signatures allow viewers to derive valuable use data and sociohistorical information to better understand the world in which digital images originated and exist. literature review web 2.0 identities and recognition theory while web 2.0 can be imagined as a highly collaborative space where social actors are able to gina schlesselman-tarango (gina.schlesselman@du.edu) holds a master of social sciences from the university of colorado denver and is currently an mlis candidate at university of colorado. mailto:gina.schlesselman@du.edu searchable signatures: context and the struggle for recognition | schlesselman-tarango 6 communicate to the world new identities, some warn that this communication is somehow engineered and performed. van dijck, in an analysis of social media, argues that it is indeed “publicity strategies [that] mediate the norms for sociality and connectivity,” and baroncelli and freitas note that web 2.0 allows people to make themselves visible through modes of spectacularization.3 though his focus is on the spectacle in fin de siècle france, clark provides some insight into the effects of spectacularization on the individual. 4 working within a historical materialist framework, clark points that with the growth of capitalism, the individual has become colonized. 5 clark further describes this colonization as “massive internal extension of the capitalist market—the invasion and restructuring of whole areas of free time, private life, leisure, and personal expression . . . the making-into-commodities of whole areas of social practice which had once been referred to casually as everyday life.” 6 here, web 2.0 is not a liberatory tool but instead a space where users are colonized to the extent that they create selves exchanged through social networking sites owned by capitalist enterprises. web 2.0, then, has created a situation in which personal time and identification can be successfully commodified. baroncelli and freitas conclude, “from that formula, personal life becomes a capital to be shared with other people—preferably, with a large audience.” 7 the problem, then, is that one’s existence is defined simply “by being seen by others” and can no longer be understood as authentic.8 despite the sophistication of the argument detailed above, there are some who view the online self, created through web 2.0, as a legitimate and authentic identity. in an account of the online self, hongladarom summarizes this position, noting that both offline and virtual identities are constructed in social environments. 9 for hongladarom, these identities are not different in essence because “what it is to be a person . . . is constituted by external factors.” 10 the online world as an external factor has the ability to affirm one’s existence, regardless of whether that existence is physical or virtual. in sum, it is the social other and not a material existence that is the authenticating factor in identity formation. there are others who validate the role that spectacle—or what also can be understood as performance—plays in identity formation. pearson calls on the work of goffman to argue, “identity-as-performance is seen as part of the flow of social interaction as individuals construct identity performances fitting their milieu.” 11 for pearson, the identity is always performed, be it through web 2.0 or otherwise. there is nothing particularly worrisome, then, about the effects of web 2.0 on the self, nor does web 2.0 threaten the authenticity of the self. identity is always performed and is in a sense a spectacle—this does not mean, however, that identity in itself is spurious. it is with this perspective of the online self as a performed albeit authentic identity that this paper further develops. before a thorough analysis of the searchable signature as an online self can be conducted, a deeper understanding of honneth’s theory of recognition is in order. information technology and libraries | september 2013 7 in his 1995 work the struggle for recognition: the moral grammar of social conflicts, honneth sets out to develop a social theory based on what he calls “morally motivated struggle.” 12 based on the habermasian concept of communicative action, honneth contends that it is through mutual recognition that “one can develop a practical relation-to-self [and can] view oneself from the normative perspective of one’s partners in interaction, as their social addressee.” 13 relation-toself is key for honneth, and he argues that a healthy relation-to-self, or what can be thought of as self-esteem, is developed when one is seen as valuable by others. beyond self-esteem, honneth points that the success of social life itself depends on “symmetrical esteem between individualized (and autonomous) subjects.” 14 for honneth, this “symmetrical esteem” can lead to solidarity between individuals. “relationships of this sort,” he explains, “can be said to be cases of ‘solidarity’ because they inspire not just passive tolerance but felt concern for what is individual and particular about the other person.” 15 that is to say that felt concern for another allows one to see the specific traits of the other as valuable in working towards common goals, and honneth imagines that in situations of “symmetrical esteem . . . every subject is free from being collectively denigrated, so that one is given the chance to experience oneself to be recognized, in light of one’s own accomplishments and abilities, as valuable for society.” 16 until this ideal is realized, however, individuals must find sites in which to struggle to be recognized as valuable social assets. according to baroncelli and freitas, it is in fact web 2.0 that provides the arena where “the contemporary demand for the visibility of the self” is able to flourish. 17 they position this argument within honneth’s framework, asserting that the visibility of self is “directed towards a quest for recognition,” and they thus conclude that web 2.0 can be understood as a “recognition market.” 18 context and its importance capturing and integrating markers of context into records, according to chowdhury, still present a challenge for many.19 “there is now a general consensus that the major challenge facing a digital library as well as a digital preservation program is that it must describe its content as well as the context sufficiently well to allow its correct interpretation by the current and future generations of users,” he contends.20 context in itself is difficult to define, let alone its myriad facets that might or might not facilitate better understanding of digital objects. dervin, in her exploration of the meaning of context, points that it is often conceptualized as the “container in which the phenomenon resides.” 21 she points that the list of factors that constitute the container and might be considered contextual is in fact “inexhaustible”—items on this list, for example, might include the gender, race, and ethnicity of those involved in a phenomenon. 22 in an indexing or digital collection environment, the goal is to determine which of these many factors ought be included in a record to best allow for discovery and use. searchable signatures: context and the struggle for recognition | schlesselman-tarango 8 others imagine context as a fluid, ever-changing process rather than as a static container of data. “in this framework,” dervin writes, “reality is in a continuous and always incomplete process of becoming.” 23 this understanding of context as changing is helpful for those working with objects that live in digital environments, especially web 2.0. certainly the interactive nature of the web has created room for a variety of users to create, share, appropriate, comment on, tag, reject, celebrate, and ultimately understand images in a multitude of contexts that might be different from one moment to the next. there are many reasons to include contextual information in records of digital objects. lee argues that by providing context, or what he describes as the “social and documentary” world “in which [a digital object] is embedded,” future users will be able to better understand the “details of our current lives.” 24 further, lee contends that context is helpful in that is illustrates the ways in which a digital object is related to other materials: relationships to other digital objects can dramatically affect the ways in which digital objects have been perceived and experienced. in order for a future user to make sense of a digital object, it could be useful for that user to know precisely what set of . . . representations—e.g. titles, tags, captions, annotations, image thumbnails, video keyframes—were associated with a digital object at a given point in time. 25 the user-generated tag, then, is a valuable representation that provides contextual information surrounding the perception and experience of the image with which it is directly related. discussion user-generated tags and traditional metadata user-generated tags have been hailed as an important stage in the evolution of image description and are said to have the potential to shape controlled vocabularies used in traditional metadata schemas. for example, in a comparison of flickr tags and index terms from the university of st. andrews library photographic archive, rorissa stresses the importance of exploring similarities and differences between indexers’ and users’ language, noting that “social tagging could serve as a platform on which to build future indexing systems.” 26 like others, rorissa hopes that continued research into user-generated social tags will be able to “bridge the semantic gap between indexerassigned terms and users’ search language.” 27 in fact, some are currently utilizing social tags in an effort to describe and facilitate access to collections. one such organization is steve: the museum social tagging project, “a place where you can help museums describe their collections by applying keywords, or tags, to objects.” 28 the organization allows users to not only view traditional metadata associated with cultural objects, but also tags generated by others. in an effort to better understand the similarities and differences between user-generated tags and the language used in traditional metadata schemas, one must compare the two systems. information technology and libraries | september 2013 9 yale university’s digital images database provides a glimpse at the ways in which traditional metadata schemas are typically used to describe images in digital library settings. most of the images included in the database are accompanied by descriptive, structural, and administrative metadata. for example, an item entitled “boy sitting on a stoop holding a pole” (see figure 1) from the university’s collection of 1957–90 andrews st. george papers provides a digital copy of the image, the image number, name of the creator, date of creation, type of original material, dimensions, copyright information, manuscript group name and number, box and folder numbers, and a credit line.29 the image is further described by the following: “man in the shed is making homemade bombs. the boy and man are also in image 45350.” 30 figure 1. “boy sitting on a stoop holding a pole” from yale university’s digital images database collection of 1957–90 andrews st. george papers, november 2012. certainly, such information is useful in library environments and provides users with helpful and formatted data to best guide the information discovery process. the finding aid for the andrews st. george collection is additionally helpful in that it includes information about provenance, access, processing, associated materials, and the creator; it also contains descriptive information about the collection by box and folder number. 31 however, if additional use data and sociohistorical searchable signatures: context and the struggle for recognition | schlesselman-tarango 10 information specific to this individual item were available, it would be most helpful in assisting users in determining the image’s greater context. a study of modes of participation on social networking sites suggests that it is now possible to supply such contextual information for digital objects that live in interactive online environments. a useful site for exploring user-generated tags associated with images is instagram, a social application designed for iphone and android.32 instagram users are able to upload and edit photos, and other users can then view, like, and comment on the shared photos. instagram users are able to follow other users and search for photos by the creator’s username or by accompanying tags. instagram, owned by facebook, is interoperable with other social networking sites, and users have the ability to share their photos on facebook, flickr, tumblr, and twitter. as of july 2012, it was reported that instagram had 80 million users, and in september 2012, the new york times reported that 5 billion photos were shared through the application.33 users are limited to 30 tags per photo, and instagram suggests that users be as specific as possible when describing an image with a tag so that communities of users with similar interests can form.34 many tags, like the information included in traditional metadata schemas, aim to best describe an image by explaining its content; for example, one user assigned the tags #kids, #nieces, #nephews, and #family to a photograph of a group of smiling children (see figure 2). like the information accompanying the photograph in the yale university digital images database, such tags provide users and viewers with tools to better determine the “aboutness” of the image at hand. information technology and libraries | september 2013 11 figure 2. photo shared on instagram assigning both descriptive tags and the searchable signature #proudaunt, november 2012. however, instagram users are repurposing the tagging function in a way that is unique to social networking sites. in addition to the descriptive tags assigned to the image of the children described above, the user also tagged the photo with the term #proudaunt (see figure 2). there is, however, no aunt (what can be assumed to be an adult female) in the photograph. this tag, then, functions to further identify the user who created or shared the photograph and does not describe the content of the image at hand. a search of the same tag, #proudaunt, demonstrates that this user is not alone in identifying as such: in november 2012, this search returned 40,202 images with the same tag and more than 58,000 images with tags derived from the same phrase (#proudaunty, #proudauntie, #proudaunties, #proudauntiemoment, and #proudaunti) (see figure 3). figure 3. list of results from #proudaunt hashtag search on instagram, november 2012. this type of user-generated tag—one that identifies the creator or sharer of the photograph yet is not necessarily meant to describe the content of the image—can be understood as a searchable signature. such identity-based tags are not found within yale university’s digital images database; the closest relative of the searchable signature is the creator’s name. while searchable, this name is not alternative, or secondary, and it was not created and does not exist in a social environment. searchable signatures: context and the struggle for recognition | schlesselman-tarango 12 currently, born-digital objects are often created and shared in a technological milieu that allows for the assignment of user-generated tags. consequently, the integration of the searchable signature into the presentation of digital objects has become part of accepted social practice and offers unique opportunities for digital library curators and users alike. until quite recently, most materials—be they photographs, manuscripts, or government documents—were not born in digital environments. however, digitization projects have been undertaken to ensure that such historical materials are more widely and eternally available. these reborn digital objects, then, have been and can be integrated into dynamic social environments. steve: the museum social tagging project, mentioned earlier in this paper, is one example of an organization that has capitalized on the social practice of user-generated tagging and is using descriptive tags along with traditional metadata to better describe reborn digital objects. it is important, then, to explore what (if any) implications the application of the searchable signature, a unique type of user-generated tag, has for historical objects that are later integrated into digital environments. searchable signatures associated with born digital images on social networking sites contain valuable information about their creators, users, and the images’ context. one cannot ignore that users will, if given the chance, also likely apply signatures to reborn digital objects in similar ways that they do to objects that have always existed in social environments. since the searchable signature is used to identify not only digital image creators, but also sharers, and if these signatures do in fact provide important insight into the sharers and their motivations, then these signatures are not to be ignored. rather than focusing on the creating, the lens through which to understand the searchable signature for reborn digital objects can be shifted to the social act of sharing: by whom, when, in which social environments, and for what purposes. a deeper analysis of the presentation of self through the searchable signature and the role that the signature plays in providing valuable contextual information for both bornand reborn-digital objects is developed below. searchable signatures and the struggle for recognition if web 2.0 indeed functions as a recognition market, then social media and social networking sites might appear to be tables at such a market. placing oneself behind a table—be it facebook, twitter, or instagram—the user is able to perform his or her online identity to passersby and effectively struggle to be recognized as a unique individual or as a member of a social group. these performances, which could be deemed narcissistic in nature, can alternatively be read as healthy attempts to self-actualize and connect to larger society.35 one such “table” in the recognition market is instagram. beyond instagram’s social nature that allows participants to interact with and follow one another, the specific role of the searchable signature is of interest to those who are concerned with struggles for recognition. rather than describing shared images, searchable signatures reflect performative yet authentic user identities. information technology and libraries | september 2013 13 mccune, in a case study of consumer production on instagram, acknowledges the potential of the tag to not only facilitate image exchange but to communicate users’ positions as members of social groups.36 through a simple search of tags, users who identify as, for example, “cat ladies,” are able to validate their identities when they see that there are many others who use the same or similar language in demonstrations of the self (see figure 4). other signatures such as #proudaunt, while not necessarily playful, still function to provide viewers with additional information about the instagram user that cannot be determined through the photo itself. the ability to find images based on these searchable signatures allows users to find others who identify in a like manner and to imagine themselves as part of a larger social group. in effect, searchable signatures allow users to be recognized as social addressees of like-minded others. positioning oneself within a group must be understood as a struggle for recognition, for to imagine oneself as part of the social fabric is also to see oneself as valuable. figure 4. list of results from #catlady hashtag search on instagram, november 2012. enabled by web 2.0, searchable signatures contain potential for marginalized peoples or groups to assert online selves to be seen and ultimately heard in a truly intersubjective landscape. it is not too much of a leap to imagine that searchable signatures might make possible the organization of individuals and groups for political purposes. in fact, in a discussion of social groups, honneth notes that “the more successful social movements are at drawing the public sphere’s attention to searchable signatures: context and the struggle for recognition | schlesselman-tarango 14 the neglected significance of the traits and abilities they collectively represent, the better their chances of raising the social worth, or indeed, the standing of their members.” 37 here, searchable signatures might provide such movements with a venue to capture the public’s attention and to effectively struggle for and gain recognition. searchable signatures and context as markers of individual and group identities, searchable signatures are unique in that they provide a snapshot of the multitude of social, historical, political, individual, and interpersonal relationships that ontologize the images with which they are paired. it is this very contextual information that is at times lacking in traditional indexing environments. by examining searchable signatures, experts and users are able to understand which individuals and groups create, use, and identify with certain images. thus, as markers of self, searchable signatures provide use data for scholars to better investigate which images are important to online individual or group identities. if the searchable signature is used in a political fashion, historians and sociologists might be able to study which types of images, for example, marginalized groups rally around, identify with, and use in their struggles for recognition. such use data also illuminates how and by whom certain digital images have been appropriated over time. for example, if a picture of a cat is first created or shared via instagram by an animal rights activist, the image might be accompanied by the searchable signature #humanforcats. this same image, shared by another user months later, might be accompanied by the #catlady signature. those interested will be able to examine how the same image has been historically used for different purposes and will be better able to grasp the evolving nature of its digital context. in addition to use data, the searchable signature provides insight into the sociohistorical context surrounding digital images. for those who perceive “reality . . . as accessible only (and always incompletely) in context, in specific historicized moments in time space” the searchable signature clarifies and makes more accessible that reality surrounding the digital image. 38 in a traditional library setting, a photo of a cat might be indexed with descriptive subject headings such as “cat,” “persian cat,” or “kitten—behavior.” however, the searchable signature #catladyforlife provides additional information on how the cat has become, for a certain social group in a specific moment in time, a trope of sorts for those who are proud of not only their relationships with their domestic pets, but of their shared values and lifestyles as well. if a historian were to dig deeper, he or she also might see that “cat lady” has historically been used in a derogatory manner to mark single, unattractive women thought to be crazy and unable to care for the great number of cats they own and that, by (re)claiming this title, women might be engaging in a struggle for recognition that extends beyond mere admiration for felines.39 chowdhury, in a continued discussion of challenges facing the digital world, asks whether it is “possible to capture the changing context along with the content of each information resource, because as we know the use and importance . . . changes significantly with time.” 40 additionally, he information technology and libraries | september 2013 15 asks, “will it be possible to re-interpret the stored digital content in the light of the changing context and user community, and thereby re-inventing the importance and use of the stored objects?” 41 it is here that the searchable signature offers use data and sociohistorical information to illuminate the (changing) value digital images have for individuals, communities, and society. conclusion clark argues that representation must be understood within the confines of what he calls “social practice.” 42 social practice, among other things, can be understood as “the overlap and interference of representations; it is their rearrangement in use.” 43 representation of self also must be understood within current social practice, and an important facet of today’s practice is web 2.0. as a social space, web 2.0 allows for the creation of disembodied self-representations. one type of such representation, the searchable signature, is a phenomenon unique to social networking sites. while many acknowledge the potential of descriptive, user-generated tags to inform or even to be used in conjunction with metadata schemas or controlled vocabularies, instagram users have created an additional, alternative use for the tag. rather than simply using tags to describe shared images, they have successfully created a route to online identity formation and recognition. searchable signatures demonstrate the power of the online self, as they allow users to struggle to be recognized as unique individuals or as parts of larger social groups. these signatures, too, might act as platforms on which social groups can assert their value and thus demand recognition. additionally, searchable signatures provide contextual information that reflects the social practice in which digital images live. while the capture and integration of such information remains a challenge for those engaged in traditional indexing, web 2.0 allows for this unique type of usergenerated tag and thus provides better understanding of the context surrounding digital images. as to the question of whether searchable signatures can be integrated into existing metadata schemas or be used to inform controlled vocabularies in library environments, it is not unreasonable to suggest that digital objects be accompanied by their supplemental yet valuable representations (e.g., searchable signatures and the like). many methods exist through which these signatures might be both gathered and displayed. certainly, a full exploration of such practices is the stuff of future research; however, some initial ideas are detailed below. one method of gathering identity-based tags would involve the active hunting down of searchable signatures. locating objects on social networking sites that are also in one’s digital collection, the indexer would identify and track associated user-generated searchable signatures. this method would require extreme diligence, high levels of comfort navigating and using web 2.0, a clear idea of which social networking sites yield the most valuable searchable signatures, and likely one or more full-time staff members devoted to such activities. even if feed systems were employed for individual digital objects, this method demands much of indexers and would likely not be sustainable over time. searchable signatures: context and the struggle for recognition | schlesselman-tarango 16 a more passive yet efficient way of gathering searchable signatures would simply be to build on methods that have shown to be successful. by creating interactive digital environments that encourage users to assign not only descriptive but also identity-based tags, indexers are freed of the time-consuming task of hunting for searchable signatures on the web. since searchable signatures have come to be part of online social practice, the assigning of them would likely be familiar to users—initially, libraries might need to prompt users to share signatures or provide them with examples. this gathering tactic could be used to harvest signatures for items that are already part of the library’s digital collection (telling us about signatures used by potential sharers) or as a means to incorporate new digital objects into the collection (telling us about signatures used by both creators and sharers). in both gathering scenarios, indexers might choose to display only the most occurring or what they deem to be the most relevant searchable signatures, or they might choose to display all such tags; decisions such as these will ultimately depend on each institution’s mission and resources. of course, if a library integrates a born-digital image into its collection and can identify the searchable signatures originally assigned to it via social networking sites or otherwise, this information should also be recorded. here, users will be able to get a glimpse of the image in its pre-library life. providing associated usernames, dates posted, and the name of the social networking sites too will assist in providing a more complete picture of the individuals or groups linked to the image. this information can provide valuable data about the information creators and sharers who use specific social platforms. the aim of this paper is to lay the theoretical groundwork to better understand the role of searchable signatures in today’s digital environment as well as the signature’s unique ability to provide context for digital images. surely, further research into the phenomenon of the searchable signature would demonstrate how it is currently used outside of instagram or as a political tool. others might consider examining the username as another arena in which individuals or groups construct and perform online identities and thus engage in struggles for recognition. usernames also might provide contextual use data and sociohistorical information that inevitably support greater understanding of digital objects. finally, further research is needed to identify how libraries could utilize the searchable signature in promotional activities and to build and cater to user communities. references 1. axel honneth, the struggle for recognition: the moral grammar of social conflicts

http://thames2thayer.com/portfolio/a-study-of-instagram/ author name and second author the use of ajax, or asynchronous javascript + xml, can result in web applications that demonstrate the flexibility, responsiveness, and usability traditionally found only in desktop software. to illustrate this, a repository metasearch user interface, ojax, has been developed. ojax is simple, unintimidating but powerful. it attempts to minimize upfront user investment and provide immediate dynamic feedback, thus encouraging experimentation and enabling enactive learning. this article introduces the ajax approach to the development of interactive web applications and discusses its implications. it then describes the ojax user interface and illustrates how it can transform the user experience. w ith the introduction of the ajax development paradigm, the dynamism and richness of desktop applications become feasible for web-based applications. ojax, a repository metasearch user interface, has been developed to illustrate the potential impact of ajax-empowered systems on the future of library software.1 this article describes the ajax method, highlights some uses of ajax technology, and discusses the implications for web applications. it goes on to illustrate the user experience offered by the ojax interface. ■ ajax in february 2005, the term ajax acquired an additional meaning: asynchronous javascript + xml.2 the concept behind this new meaning, however, has existed in various forms for several years. ajax is not a single technology but a general approach to the development of interactive web applications. as the name implies, it describes the use of javascript and xml to enable asynchronous communication between browser clients and server-side systems. as explained by garrett, the classic web application model involves user actions triggering a hypertext transfer protocol (http) request to a web server.3 the latter processes the request and returns an entire hypertext markup language (html) page. every time the client makes a request to the server, it must wait for a response, thus potentially delaying the user. this is particularly true for large data sets. but research demonstrates that response times of less than one second are required when moving between pages if unhindered navigation is to be facilitated through an information space.4 the aim of ajax is to avoid this wait. the user loads not only a web page, but also an ajax engine written in javascript. users interact with this engine in the same way that they would with an html page, except that instead of every action resulting in an http request for an entire new page, user actions generate javascript calls to the ajax engine. if the engine needs data from the server, it requests this asynchronously in the background. thus, rather than requiring the whole page to be refreshed, the javascript can make rapid incremental updates to any element of the user interface via brief requests to the server. this means that the traditional page-based model used by web applications can be abandoned; hence, the pacing of user interaction with the client becomes independent of the interaction between client and server. xmlhttprequest is a collection of application programming interfaces (apis) that use http and javascript to enable transfer of data between web servers and web applications.5 initially developed by microsoft, xmlhttprequest has become a de facto standard for javascript data retrieval and is implemented in most modern browsers. it is commonly used in the ajax paradigm. the data accessed from the http server is usually in extensible markup language (xml) but another format, such as javascript object notation, could be used.6 applications of ajax google is the most significant user of ajax technology to date. most of its recent innovations, including gmail, google suggest, google groups, and google maps, employ the paradigm.7 the use of ajax in google suggest improves the traditional google interface by offering real-time suggestions as the user enters a term in the search field. for example, if the user enters xm, google suggest might offer refinements such as xm radio, xml, and xmods. experimental ajax-based auto-completion features are appearing in a range of software.8 shanahan has applied the same ideas to the amazon online bookshop.9 his experimental site, zuggest, extends the concept of auto-completion: as the user enters a term, the system automatically triggers a search without the need to hit a search button. the potential of ajax to improve the responsiveness and richness of library applications has not been lost on the library community.10 several interesting experiments have been tried. at oclc, for example, a “suggest-like service,” based on controlled headings from the worldjudith wusteman and pádraig o’hiceadha using ajax to empower dynamic searching | wusteman 57 using ajax to empower dynamic searching judith wusteman (judith.wusteman@ucd.ie) is a lecturer in the ucd school of information and library studies, university college dublin, ireland. 58 information technology and libraries | june 2006 wide union catalog, worldcat, has been implemented.11 ajax has also been used in the oclc deweybrowser.12 the main page of this browser includes four iframes, or inline frames, three for the three levels of dewey decimal classification and a fourth for record display.13 the use of ajax allows information in each iframe to be updated independently without having to reload the entire page. implications of ajax there have been many attempts to enable asynchronous background transactions with a server. among alternatives to ajax are flash, java applets, and the new breed of xml user-interface language formats such as xml user interface language (xul) and extensible application markup language (xaml).14 these all have their place, particularly languages such as xul. the latter is ideal for use in mozilla extensions, for example. combinations of the above can and are being used together; xul and ajax are both used in the firefox extension version of google suggest.15 the main advantage of ajax over these alternative approaches is that it is nonproprietary and is supported by any browser that supports javascript and xmlhttprequest—hence, by any modern browser. it could be validly argued that complex client-side javascript is not ideal. in addition to the errors to which complex scripting can be prone, there are accessibility issues. best practice requires that javascript interaction adds to the basic functionality of web-based content that must remain accessible and usable without the javascript.16 an alternative non-javascript interface to gmail was recently implemented to deal with just this issue. a move away from scripting would, in theory, be a positive step for the web. in practice, however, procedural approaches continue to be more popular; attempts to supplant them, as epitomized by xhtml 2.0, simply alienate developers.17 it might be assumed that the use of ajax technology would result in a heavier network load due to an increase in the number of requests made to the server. this is a misconception in most cases. indeed, ajax can dramatically reduce the network load of web applications, as it enables them to separate data from the graphical user interface (gui) used to display it. for example, each results page presented by a traditional search engine delivers, not only the results data, but also the html required to render the gui for that page. an ajax application could deliver the gui just once and, after that, deliver data only. this would also be possible via the careful use of frames; the latter could be regarded as an ajax-style technology but without all of ajax’s advantages. ■ from client-server to soa the dominant model for building network applications is the client/server approach, in which client software is installed as a desktop application and data generally reside on a server, usually in a database.18 this can work well in a homogenous single-site computing environment. but institutions and consortia are likely to be heterogeneous and geographically distributed. pcs, macs, and cell phones will all need access to the applications, and linux may require support alongside windows. even if an organization standardizes solely on windows, different versions of the latter will have to be supported, as will multiple versions of those ubiquitous dynamic link libraries (dlls). indeed, the problems of obtaining and managing conflicting dlls have spawned the term “dll hell.”19 in web applications, a standard client, the browser, is installed on the desktop but most of the logic, as well as the data, reside on the server. of course, the browser developers still have to worry about “dll hell,” but this need not concern the rest of us. “speed must be the overriding design criterion” for web pages.20 but the interactivity and response times possible with client/server applications are still not available to traditional web applications. this is where ajax comes in: it offers, to date, the best of the web application and client/server worlds. much of the activity is moved back to the desktop via client-side code. but the advantages of web applications are not lost: the browser is still the standard client. service-oriented architecture (soa) is an increasingly popular approach to the delivery of applications to heterogeneous computing environments and geographically dispersed user populations.21 soa refers to the move away from monolithic applications toward smaller, reusable services with discrete functionality. such services can be combined and recombined to deliver different applications to users. web services is an implementation of soa principles.22 the term describes the use of technologies such as xml to enable the seamless interoperability of web-based applications. ajax enables web services and hence enables soa principles. thus, the adoption of ajax facilitates the move toward soa and all the advantages of reuse and integration that this offers. ■ arc arc is an experimental open-source metasearch package available for download from the sourceforge opensource foundry.23 it can be configured to harvest open using ajax to empower dynamic searching | wusteman 59 archives initiative-protocol for metadata harvesting (oai-pmh)-compliant data from multiple repositories.24 the harvested results are stored in a relational database and can be searched using basic web forms. arc’s advanced search form is illustrated in figure 1. ■ applying ajax to the search gui the use of ajax has the potential to narrow the gulf between the responsiveness of guis for web applications and those for desktop applications. the flexibility, usability, and richness of the latter are now possible for the former. the ojax gui, illustrated in figure 2, has been developed to demonstrate how ajax can improve the richness of arc-like guis. ojax, including full source code, is available under the open-source apache license and is hosted on sourceforge.25 ojax comprises a client-side gui, implemented in javascript and html, and server-side metasearch web services, implemented in java. the web services connect directly to a metasearch database created by arc from harvested repositories. the database connectivity leverages several libraries from the apache jakarta project, which provides open-source java solutions.26 ■ development process the ojax gui was developed iteratively using agile software development methods.27 features were added incrementally and feedback gained from a proxy user. in order to gain an in-depth understanding of the system and the implications for the remainder of the gui, features were initially built from scratch, using objectoriented javascript.they were then rebuilt using three open-source javascript libraries: prototype, script.aculo .us, and rico.28 prototype provides base ajax capability. it also includes advanced functionality for object-oriented javascript, such as multiple inheritance. the other two libraries are built on top of prototype. the script.aculo. us library specializes in dynamic effects, such as those used in auto-completion. the rico library, developed by sabre, provides other key javascript effects—for example, dynamic scrollable areas and dynamic sorting.29 ■ storyboard one of the aims of the national information standards organization (niso) metasearch initiative is to enable all library users to “enjoy the same easy searching found in web-based services like google.”30 adopting this approach, ojax incorporates the increasingly common concept of the search bar, popularized by the google toolbar.31 ojax aims to be as simple, uncluttered, and unthreatening as possible. the goal is to reflect the simple-search experience while, at the same time, providing the power of an advanced search. thus, the user interface has been kept as simple as possible while maintaining equivalent functionality with the arc advanced search interface. all arc functionality, with the exception of the grouping feature, is provided. to help the intuitive flow of the operation, the fields are set out as a sentence: find [term(s)] in [all archives] from [earliest year] until [this year] in [all subjects] tool tips are available for text-entry fields. by default, searching is on author, title, and abstract. these fields map to the creator, title, and description dublin core metadata fields harvested from the original repositories.32 the search can be restricted by deselecting unwanted fields. arc supports both mysql and oracle databases.33 mysql has been chosen for ojax as mysql is an open-source database. boolean search syntax has been figure 1. arc’s advanced search form figure 2. the ojax metasearch user interface 60 information technology and libraries | june 2006 implemented in ojax to allow for more powerful searching. the syntax is similar to that used by google in that it identifies and/or and exact phrase functionality by +/and “ ”. hence it preserves the user’s familiarity with basic google search syntax. however, it is not as powerful as the full google search syntax; for example, it does not support query modifiers such as: intitle: 34 the focus of this research is the application of ajax to the search gui and not the optimization of the power or expressive capability of the underlying search engine. however, the implementation of an alternative back end that uses a full-text search engine, such as apache lucene, would improve the expressive power of advanced queries.35 full-text search expressiveness is likely to be key to the usability of ojax, ensuring its adequacy for the advanced user without alienating the novice. ■ unifying the user interface one of the main aims of ojax is the unification of the user interface. instead of offering distinct options for simple and advanced search and for refining a completed search, the interface is sufficiently dynamic to make this unnecessary. the user need never navigate between pages because all options, both simple and advanced, are available from the same page. and all results are made available on that same page in the form of a scrollable list. the only point at which a new page is presented is when the resource identifier of a result is clicked. at this stage, a pop-up window, external to the ojax session, displays the full metadata for that resource. this page is generated by the external repository from which the record was originally harvested. simple and advanced search options are usually kept separate because most users are unwilling or unable to use the latter.36 furthermore, the design of existing search-user interfaces is based on the assumption that the retrieval of results will be sufficiently time-consuming that users will want to have selected all options beforehand. with ojax, however, users do not have to make a complete choice of all the options they might want to try before they see any results. as data are entered, answers flow to accommodate them. because the interface is so dynamic and responsive and because users are given immediate feedback, they do not have to be concerned about wasting time due to the wrong choice of search options. users iterate toward the search results they require by manipulating the results in real time. the reduced level of investment that users must make before they achieve any return from the system should encourage them to experiment, hence promoting enactive learning. ■ auto-completion in order to provide instant feedback to the user, the search-terms field and the subject field use ajax to autocomplete user entries. figure 3 illustrates the result of typing smith in the search-terms field. a list is automatically dropped down that itemizes all matches and the number of their occurrences. users select the term they want, the entire field is automatically completed, and a search is triggered. the arc system denormalizes some of the harvested data before saving them in its database. for example, it merges all the author fields into one single field, each name separated by a bar character. to enable the ojax auto-completion feature, it was necessary to renormalize the names. a new table is used to store each name in a separate row; names are referenced by the resource identifier. to enable this, arc’s indexing code was updated so that it creates this table as it indexes records extracted from the oai-pmh feed. in its initial implementation, ojax uses a simple algorithm for auto-completion. future work will involve developing a more complex heuristic that will return results more closely satisfying user requirements. ■ auto-search as already mentioned, a central theme of ojax is the attempt to reduce the commitment necessary from users before they receive feedback on their actions. one way in which dynamic feedback is provided is the triggering of an immediate search whenever an entire option has been selected. examples of entire options include choice of an archive or year and acceptance of a suggested autocompletion. in addition, the following heuristics are used to identify when a user is likely to have finished entering a search term and, thus, when a search should be triggered: 1. entering a space character in the search-terms field or subject field 2. tabbing out of a field after having modified its contents 3. five seconds of user inactivity for a modified field the third heuristic aims to catch some of the edge cases that the other heuristics may miss. it is assumed likely that a term has been completed if a user has made no edits in the last five seconds. as each term will be using ajax to empower dynamic searching | wusteman 61 separated by a space, it is only the last term in a search phrase that is likely not to trigger an auto-search via the first heuristic. users can click the search button whenever they wish, but they should never have to click it. the zuggest system abandons the search button entirely; ojax retains it, mainly in order to avoid confounding user expectations.37 while a search is in progress, the search button is greyed out and acquires a red border. this is particularly useful in alerting the user that a search has been automatically triggered. this is the only feature of ojax that may have an impact on network load in terms of slightly higher traffic. however, the increased number of requests is offset by a reduction in the size of each response because the gui is not downloaded with it. for example, initiating a search in arc results in an average response size of 57.32k. the response is in the form of a complete html page. initiating a search in ojax results in an average response size of 7.96k. the latter comprises a web service response in xml. in other words, more than seven ojax autosearches would have to be triggered before the size of the initial search result in arc was exceeded. ■ dynamic archive list the use of ajax enables a static html page to contain a small component of dynamic data without the entire page having to be dynamically generated on the server. ojax illustrates this: the contents of the drop-down box listing the searchable archives are not hard-coded in the html page. rather, when the page is loaded, an ajax request for the set of available archives is generated. this is a useful technique; static html pages can be cached by browsers and proxy servers, and only the dynamic portion of the data, perhaps those used to personalize the page, need be downloaded at the start of a new session. ■ dynamic scrolling searches commonly produce thousands of results. typical systems, such as google and arc, make these results available via a succession of separate pages, thus requiring users to navigate between them. finding information by navigating multiple pages can take longer than scrolling down a single page, and users rarely look beyond the second page of search results.38 to avoid these problems and to encourage users to look at more of the available results, those results could be made available in one scrollable list. but, in a typical non-ajax application, accessing a scrollable list of, say, two thousand items would require the entire list to be downloaded via one enormous html page. this would be a huge operation; if it did not crash the browser, it would, at least, result in a substantial wait for the user. the rico library provides a feature to enable dynamic scrollable areas. it uses ajax to fetch more records from the server when the user begins to scroll off the visible area. this is used in the display of search results in ojax, as illustrated in figure 4. to the user, it appears that the scrollable list is seamless and that all 4,678 search results are already downloaded. in fact, only 386 have been downloaded. the rest are available at the server. as the user scrolls further down, say to item 396, an ajax request is made for the next ten items. any item downloaded is cached by the ajax engine and need not be requested again if, for example, the user scrolls back up the list. a dynamic information panel is available to the right of the scroll bar. it shows the current scroll position in relation to the beginning and end of the results set. in figure 3. auto-completion in the search terms field figure 4. display of search results and dynamic information panel 62 information technology and libraries | june 2006 figure 4, the information panel indicates that there are 4,678 results for this particular search and that the current scroll position is at result number 386. this number updates instantly during scrolling, preserving the illusion that all results have been downloaded and providing users with dynamic feedback on their progress through the results set. this means that users do not have to wait for the main results window to refresh to identify their current position. ■ auto-expansion of results ojax aims to provide a compact display of key information, enabling users to see multiple results simultaneously. it also aims to provide simple access to full result details without requiring navigation to a new web page. in the initial results display, only one line each of the title, authors, and subject fields, and two lines of the abstract, are shown for each item. as the cursor is placed on the relevant field, the display expands to show any hidden detail in that field. at the same time, the background color of the field changes to blue. when the cursor is placed on the bar containing the resource identifier, all display fields for that item are expanded, as illustrated in figure 5. this expansion is enabled via simple cascading style sheet (css) features. for example, the following css declaration hides all but the first line of authors: #searchresults td div { overflow:hidden; height: 1.1em } when the cursor is placed on the author details, the overflow becomes visible and the display field changes its dimensions to fit the text inside it: #searchresults td div:hover { overflow:visible; height:auto } ■ sorting results another method used by ojax to minimize upfront user investment is to provide initial search results before requiring the user to decide on sort options. because results are available so quickly and because they can be re-sorted so rapidly, it is not necessary to offer pre-search selection of sort options. ajax facilitates rapid presentation of results; after a re-sort, only those on the first screen must be downloaded before they can be presented to the user. results may be sorted by title, author, subject, abstract, and resource identifier. these options are listed on the gray bar immediately above the results list. clicking one of these options sorts the results in ascending order; an upward-pointing arrow appears to the right of the sort option chosen, as illustrated in figure 6. clicking on the option again sorts in descending order and reverses the direction of the arrow. clicking on the arrow removes the sort; the results revert to their original order. functionality for the sort feature is provided by the rico javascript library. server-side implementation supports these features by caching search results so that it is not necessary to regenerate them via a database query each time. figure 5. auto-expansion of all fields for item number 386 figure 6. results being sorted in ascending order by title using ajax to empower dynamic searching | wusteman 63 ■ search history several experimental systems—for example, zuggest— have employed ajax to facilitate a search-history feature. a similar feature could be provided for ojax. a button could be added to the right of the results list. when chosen, it could expand a collapsible search-history sidebar. as the cursor was placed on one of the previous searches listed in the sidebar, a call out, that is, a speech bubble, could be displayed. this could provide further information such as the number of matches for that search and a summary of the search results clicked on by the user. clicking one of the previous searches would restore those search results to the main results window. this feature would take advantage of the ajax persistent javascript engine to maintain the history. its use could help counter concerns about ajax technology “breaking” the back button; the feature could be implemented so that the back button returned the user to the previous entry in the search history.39 in fact, this implementation of back-button functionality could be more useful than the implementation in google, where hitting the back button is likely to take the user to an interim results page; for example, it might simply take the user from page 3 of results to page 2 of results. ■ scrapbook users browsing through search results on ojax would require some simple method of maintaining a record of those resource details that interested them. ajax could enable the development of a useful scrapbook feature to which such resource details could be copied and stored in the persistent javascript engine. ojax could further leverage a shared bookmark web service, such as del. icio.us or furl, to save the scrapbook for use in future sessions and to share it with other members of a research or interest group.40 ■ potential developments for ojax as well as searching a database of harvested metadata, the ojax user interface could also be used to search an oai-pmh-compliant repository directly. with appropriate implementation, all of ojax’s current features could be made available, apart from auto-completion. a recent development has enabled the direct indexing of repositories by google using oai-pmh.41 the latter provides google with additional metadata that can be searched via the google web services apis. the current ojax web services could be replaced by the google apis, thus eliminating the need for ojax to host any server-side components. hence, ojax could become an alternative gui for google searching. ■ conclusion ojax demonstrates that the use of ajax can enable features in web applications that, until now, have been restricted to desktop applications. in ojax, it facilitates a simple, nonthreatening, but powerful search user interface. page navigation is eliminated; dynamic feedback and a low initial investment on the part of users encourage experimentation and enable enactive learning. the use of ajax could similarly transform other web applications aimed at library patrons. however, ajax is still maturing, and the barrier to entry for developers remains high. we are a long way from an ajax button appearing in dreamweaver. reusable, well-tested components, such as rico, and software frameworks, such as ruby on rails, sun’s j2ee framework, and microsoft’s atlas, will help to make ajax technology accessible to a wider range of developers.42 as with all new technologies, there is a temptation to use ajax simply because it exists. as ajax matures, it is important that its focus does not become the enabling of “cool” features but remains the optimization of the user experience. references and notes 1. ojax homepage,

technology mark dehmlow information technology and libraries | march 2014 4 for this issue’s editorial, i thought i would set aside the trendy topics like discovery, the clo ud, and open . . . well, everything—source, data, science—and instead focus on an area that i think has more long-term implications for technologists and libraries. for technologists in libraries, probably any industry really, i believe our most important challenges aren’t technical at all. for the average “techie,” even if an issue is complex, it is often finite and ultimately traceable to a root cause—the programmer left off a semi-colon in a line of code, the support person forgot to plug in the network cable, or the systems administrator had a server choke after a critical kernel error. debugging people issues, on the other hand, is much less reductive. people are nothing but variables who respond to conflict with emotion and can become entrenched in their perspectives (right or wrong). at a minimum, people are unpredictable. the skill set to navigate people and personalities requires patience, flexibility, seeing the importance of the relationship through the 1s and 0s, and often developing mutual trust. working with technology benefits from one’s intelligence (iq), but working with people requires a deeper connection to perception, self-awareness, body language, and emotions, all parts of emotional intelligence (eq). eq is relevant to all areas of life and work, but i think particularly relevant to technology workers. of particular importance are eq traits related to emotional regulation, self-awareness, and the ability to pick up social queues. my primary reasoning for this is that technology is (1) fairly opaque to people outside of technology areas and (2) technology is driving so much of the rapid change we are experiencing in libraries. it units in traditional organizations have a significant challenge because many root issues in technology are not well understood, and change is uncomfortable for most, so it is easy to resent technology for being such a strong catalyst for change. as a result, it is becoming more incumbent upon us in technology to not only instantiate change in our organizations but also to help manage that change through clear communication, clear expectation setting, defining reasonable timeframes that accommodate individuals’ needs to adapt to change, a commitment to shift behavior through influence, and just plain old really good listening. i would like to issue a bit of a challenge to technology managers as you are making hiring decisions. if you want the best possible working relationships with other functional areas in the library, especially traditional areas, spend time evaluating candidates for soft skills like a relaxed demeanor; patience; clear, but not condescending, communication; and a personal commitment to mark dehmlow (mdehmlow@nd.edu), a member of lita and the ital editorial board, is director, information technology program, hesburgh libraries, university of notre dame, south bend, indiana. editorial board thoughts: a considerable technology asset | dehmlow 5 serving others. these skills are very hard to teach. they can be developed if one is committed to developing them, but more often than not, they are innate. if a candidate has those traits as a base but also has an aptitude for understanding technology, that individual will likely be the kind of employee people will want to keep, certainly much more so than someone who has incredible technical skill but little social intelligence. for those who are interested in developing their eq, there are many of tools available—a million management books on team building, servant leadership, influencing coworkers, providing excellent service, etc. personally, i have found that developing a better sense of self-awareness is one of the best ways to increase one’s eq. tests such as the meyers briggs type indicator ,1 the strategic leadership type indicator ,2 and the disc,3 which categorize your personality and work-style traits, can be very effective tools for understanding how you approach your work and how your work style may affect your peers. combined with a willingness to flex your style based on the personalities of your coworkers, these can be very powerful tools for influencing outcomes. most importantly, i have found putting the importance of the relationship above the task or goal can make a remarkable difference in cultivating trust and collaboration. self-awareness and flexible approaches not only have the opportunity to improve internal relationships between technology and traditional functional areas of the library, but between techies and end users. we are using technology in many new creative ways to support end users, meaning techies are more and more likely to have direct contact with users. in many ways, our reputation as a committed service profession will be affected by out tech staffs’ ability to interact well with end users, and ultimately, i believe the proportion of our tech staff that have a high eq could be one the strongest predictor s of the long-term success for technology teams in libraries. references 1. “my mbti personality type,” the myers briggs foundation, http://www.myersbriggs.org/mymbti-personality-type/mbti-basics. 2.

at 50: the 1980s in review mark dehmlow information technology and libraries | september 2018 8 mark dehmlow (mdehmlow@nd.edu) is director, library information technology at the hesburgh libraries, university of notre dame. my view of library technology in the 1980s through the lens of journal of library automation (jola) and its successor information technology and libraries (ital) is a bit skewed by my age. i am a gen-xer and much of my professional perspective has been shaped by the last two decades in libraries. while i am cognizant of our technical past, my perspective is very much grounded in the technical present. in a way, i think that context made my experience reviewing the 1980s in jola and ital all the more fun. the most pronounced event for the journal during the 1980s was the transition from the journal of library automation to information technology and libraries between 1981 to 1982. the rationale for this change is perhaps best captured through the context set in the guest editorial “old wine in new bottles?” by kenney in the first issue of ital: “proliferating technologies, the trend toward integration of some of these technologies into new systems, and rapidly increasing adoption of technology-based systems of all types in libraries .…”1 the article grounds us in the anxieties and challenges of the decade surrounding an accelerating change in technology. libraries were evolving from implementing systems of “automation,” a term that focuses more on processes, to broadening their view to “information technology,” which is more of a discipline — an ecosystem made up of technology, process, systems, standards, policies, etc. in a way, the article acknowledges the departure of libraries from their adolescent technological pasts to their young adult present for which the 80s would be the background. perhaps no other event is more technologically significant during the decade than the standardization of the internet. while the concept of networks and a network of networks, e.g. the internet, was conceptualized in the 1960s, it was the development of the tcp/ip network protocol that is the most consequential event because it made it possible to interconnect computer systems using a common means of communication. while the internet wouldn’t become ubiquitously popularized until the early 1990s with the emergence of the world wide web, the internet was active and alive well before that and, in its early state, was critical to the emergence and evolution of library technologies. from the first issue through the last of the 1980s, ital references the term “online” frequently. the “online” of the 80s however was largely text based, where systems were interconnected using lightweight terminals to navigate browse and search systems. it was not unlike a massive “choose your own adventure book,” skipping from menu to menu to find what you were looking for. throughout my review, i was happy to see a small, but significant, percentage of international articles that focused on character sets, automation, and collection comparisons in countries like kuwait, australia, china, and israel. diversity is a cornerstone for lita and ala and the journal has continued this trend to encourage the submission of articles from outside of the u.s. the 1980s volumes of ital traversed a plethora of topics ranging from measuring system the 1980s in review | dehmlow 9 https://doi.org/10.6017/ital.v37i3.10749 performance (efficiency was important during a time when computing was relativ ely slow and expensive) to how to use library systems to provide data that can be used to make business decisions. over the decade, there was a significant focus on library organizations coming to terms with new technology, e.g. the automation of circulation, acquisitions, and the marc bibliographic record. there were several articles that discussed the complications, costs, and best practices for converting card-catalog metadata to electronic records and several other articles that detailed large barcoding projects. the largest number of articles on a single topic focused on the automation and management of authority control in automated library systems. there were articles on the emergence of research databases often delivered as applications on cd-roms which would then be installed on microcomputers. the term “microcomputer” was frequently used because the 80s saw the emergence of the personal computer in the work environment, a transformative step in enabling staff and patrons alike to access online library services and applications to support their research and work. electronic mail was in its infancy and became a novel way to share information with end users across a campus. several articles focused on the physical design of search terminals and optimizing the ergonomics of computers. there were also many articles about designing the best opac interface for users, ranging from how to present bibliographic records to users, to what information should be sent to printers, to early efforts to extend local catalogs with article-based metadata. many of these topics have parallels today. instead of only analyzing statistical usage data we can pull from our systems, libraries are striving to develop predictive analytics, leveraging big-data from across an assortment of institutions. i found the 1988 article “investigating computer anxiety in an academic library,” which examines staff resistance to technology and change to be as apropos today as it was then.2 cd-roms have gone the way of the feathered and overly hairsprayed coifs of the 80s and have largely been superseded by hard drives and solid state flash media that can hold significantly more data and can transfer data more rapidly. the current decade of the 2010s has been dedicated to providing the optimal search experience for our end users as we have broadened our efforts to the discovery of all scholarly information, not just what is held in our collections. and of course, instead of adding a few article abstracting resources to our catalogs in an innovative, but difficult to sustain manner, the commercial sector has created web-scale mega-indexes that are integrated with our catalogs and offer the promise of searching a predominant amount of the scholarly record. there was a really interesting thread of articles over the decade that traced the evolution of the ils in libraries. there were articles about how to develop automation systems for libraries, the various functions that could be automated — cataloging, circulation, acquisitions, etc. — and evaluation projects for commercial systems. if the 2000s was the era of consolidation, the early 1980s could easily represent the era of proliferation. the decade nicely traces the first two generations of library systems, starting with university-developed automation and database backed systems and the migration of many of those systems to vendors. the northwestern university-based notis system was referenced a lot and there were some mentions of oclc’s acquisition and distribution of the ls/2000 system. this part of our automation history is a palpable reminder that libraries have been innovative leaders in technology for decades, often developing systems ahead of the commercial industry in an effort to meet our evolving service portfolios. this early strategy for libraries mirrors recent developments of institutional repositories, current research information systems (criss), and faculty profiling systems like vivo that were developed before the commercial sector saw the feasibility of commercialization. information technology and libraries | september 2018 10 the cycle of selecting and implementing a new integrated library system is something that m any organizations are faced with again. the only difference is that the commercial sector has entered into the development of the 4th or 5th generation of integrated library systems, many of which are coming with data services integrated and most of them are implemented in the cloud. in addition to seeing our technically rudimentary past, there were several articles over the decade that discussed especially innovative ideas or that anticipated future technologies. a 1983 article by tamas doszkocs which was written long before the emergence of google is an early revelation that regular patrons struggle to use expert systems that require normalized and boolean searching strategies. not surprising is the conclusion that users lean organically toward natural language searching, but even then we were having the expert experience vs. intuitive experience debate in the profession: “the development of alternative interfaces, specifically designed to facilitate direct end user interaction in information retrieval systems, is a relatively new phenomenon.”3 the 1984 article, “packet radio for library automation,” is about eliminating the challenges of retrofitting buildings with cabling to connect lan networks by using radio based interfaces.4 could this be an early precursor to wifi? there is the 1985 article titled “microcomputer based faculty-profile” about using a local database management application on a pc to create an index of faculty publications and university publishing trends.5 this is nearly three decades before the popularization of the cris and faculty profile system. in 1986, there is an article “integrating subject pathfinders into a geac ils: a marc-formatted record approach,” an article that made me think about how library websites are structured, and the current trend of developing online research guides and making them discoverable in our websites as a research support tool.6 and finally, i was struck by the innovative approach in 1987’s “remote interactive online support,” wherein the authors wrote about using hardware to make simultaneous shell connections to a search interface so they could give live search guidance to researchers remotely. 7 we take remote technical support for granted now, but in the late 80s, this required several complicated steps to achieve. the 80s were an exciting time for technology development and a decade that is rife with technical evolution. i think this quote from the article “1981 and beyond: visions and decisions” by fasana in the journal of library automation best elucidates the deep connection between the past and the future, “library managers are currently confronted with a dynamic environment in which they are attempting simultaneously to plan library services and systems for the future, and to control the rate and direction of change.”8 this still holds true. library managers are still planning services in a rapidly changing environment, except, i like to think we have learned to live with change that we cannot control the rate nor direction of. 1 b. kenney, “guest editorial: old wine in new bottles?,”

proquest pg. 96 new strategies in library services organization: consortia university libraries in spain miguel duarte barrionuevo new political, economic, and technological developments, as well as the growth of information markets, in spain have created a foundation for the creation of library consortia. the author describes the process by which different regions in spain have organized university library consortia. s panish libraries are public entities that depend either on central or local governments and are funded through either the national general budget or the regional government (comunidades aut6nomas) budget. on one hand, the player at the national level is the education and culture ministry, which contributes to the fifty-two state public libraries and shares jurisdiction with the regional government. on the other hand, universities are self-governed institutions of a public nature regulated by the ley de reforma universitaria, or university reform law, which was approved by the spanish parliament in 1983 to promote scientific study and greater selfgovernment of spanish universities. universities have their own budget, and they are mainly funded by the regional government. the university library system is currently made of about fifty public libraries and twelve private libraries. since the second half of the 1980s, a new philosophy concerning public services has spread in spain, as in other european countries: a philosophy calling for higher quality and more efficiency in the management and administration of the public capital. there has also arisen a claim to the government's satisfactory use of public funds as a social right, as well as a claim to a return on that capital in social terms. this is where libraries' public services come into play. there is a clear interest in all the aspects related to the introduction of new techniques in management. quality management, effectiveness and efficiency measuring, costs control, services assessment, and users content or analysis from the stakeholders' point of view are concepts that emerge in university libraries. in order to adjust to the circumstances, universities are changing their management procedures, and university libraries have been forced into managing their "business" according to managerial criteria. the commonality of their activities, and the relaxation of geographical boundaries fostered by information technologies, have encouraged libraries to join consortia in order to remain relevant in the current library services context. such concepts as the "electronic," "digital," and miguel duarte barrionuevo is head director of the central library of the university of cadiz (andalucia), and an active contributor of the university libraries consortium of andaluc1a. 96 information technology and libraries i june 2000 "virtual" libraries lead, from my point of view, to a different configuration in the library services context; they have pushed the library managers to consider strategically where they are and what is their most adequate position within this new configuration. departments dealing with information are to be wider, more heterogeneous, and multidisciplinary. new organization strategies need to be defined in order to offer services in a different way when library managers are forced to obtain the best results out of their limited resources, the organization of consortia represents a qualitative leap forward in cooperation, efficiency, and cost-savings. library consortia aim to share resources and to promote participation on the basis of the mutual benefit of the libraries involved and, although the concepts of cooperation, coordination, and sharing resources are not new in the library world, the organization of library consortia introduces a major level of commitment and involvement among the participants. i new settings, new facts libraries are going through a crisis. a library is still an institution with a strong traditional character, but its traditional duties as depository of knowledge no longer justify its costs, and the crisis is exacerbated by an accelerated technological and informative revolution. 1 within the changing atmosphere of the spanish university in the last few years, goals and objectives are affected by a number of socioeconomic, institutional, and technological factors, as well as others with an internal character that push these institutions to move toward change as an opportunity to maintain continuous improvement. materials and services are more expensive, and technology is more sophisticated every day, which leads to a need for strong investments. the public financing funds are more and more limited while the costs are growing. the university, in general, is suffering from a lack of efficiency and organizational flexibility; staff rejects monotonous tasks and holds high expectations; the fast dynamics of the implementation of information technology in the last few years has caused a very serious imbalance in the skill levels of people and in job-position demands. all these factors generate a new setting of weaknesses and hopes to which the university libraries have to respond in order to maintain their competitive advantages. i technology technology has recently become a strategic element in the development of libraries. technology is more and more sophisticated and its life is shorter. its use implies reproduced with permission of the copyright owner. further reproduction prohibited without permission. the need of strong investments in computer and communication infrastructure. i economical pressure on information market agents materials costs have diversified and arc more and more costly, with annual growths far exceeding even inflation rate levels. an absolute change has been produced in the supply and demand of the information market, which causes the agent's utter disorientation: the publishing sector is adapting very slowly to the electronic context; the distribution sector needs a deep technological and organizational transformation (few spanish suppliers offer added value services such as cataloguing, outsourcing, or material preparation-puvill libras, or filial multinationals such as blackwell or dawson are exceptions). electronic data interchange, a european standard like sisac, is not a standard format among the sector and there is not a national supplier that offers services of the approval plans type. additionally, the agents of the information market are very conditioned by the change of the demand orientation. specialized users (teachers, researchers, thesis students, etc.) demand from libraries electronic resources, quick information, and access at all times from remote locations. this conflicts with the restrictive tendencies in the maintenance of the public services and drastic budget cuts. libraries are forced to obtain the highest possible ratio of efficiency in the use of the fewest resources. i total quality management implementation and other management techniques the result is implementation of total quality management (tqm), which guarantees quality of services. it is important to consider tqm as an instrument that develops organizational strategies. it is a continuous process developed in order to replace obsolete types of organization, to orient the corporate activity as a permanent basis to the processing optimization, and to obtain a coherent relation between the efficacy in the reaching of objectives and the efficiency in the use of resources. changes in the editorial industry, the budget cuts, the quick expansion of electronic resources, the new price politics, and the problems related to copyright and intellectual property form the new setting. in this context, the consortia organization is considered by the university and library managers as a means to face the challenges which the new settings imply, to unify their pressure capacity with regard to the different agents, and to take advantage of the system's strength in order to adjust to the new situation and improve their competitive advantage. i adequate information technologies the spanish university libraries are connected to the academic information network upheld by rediris, a scientific-technical installation that depends on the science and technology office of the prime minister. the main line that maintains the redlris services is formed by seventeen nodes in each region (comunidad aut6noma), connected by atm circuits on atm accesses of 34/155 mbps. each node is formed by a set of communication equipment that allows the coordination of the main transmission means and of the access lines from the centers of each regions. redlris participates in the ten-34 project, which aims at building up an ip paneuropean net of 34 mbps, that interconnects us with the different academic and research nets and that is planned to become a ten-135 in 1999.2 on the other hand, the region (comunidad aut6noma) incorporates added value elements to the net segments they manage, such as faster access speeds that allow centralized architecture (for instance, union catalogue consortia libraries of galicia is managed through a broad band net of 155 mbps). the region also allows access to databases in cd-rom and electronic formats orientated to the final users in a regional context. for instance, the scientific computer center of andalucia manages twenty-two databases in cd-rom and other electronic formats that can be searched by all the andalusian universities and research centers through the andalusian scientific research net. homogeneous automation level the automation process of the library services, initiated at the end of the decade of the '80s, is practically completed. dobys-libis, libertas, vrls, absys, and sabini are the most widely used library management systems. 3 since 1997 some libraries have updated their library automation system to unicom (sirsi) and innopac (innovative interfaces). the spanish university libraries have a homogeneous automation level and can establish projects from the consortia perspective, such as regional union catalogs, sharing electronic information resources, and shared purchase policies. favourable political situation traditionally, the cooperative efforts have obtained little offical support. however, in the last years, a positive attitude can be perceived from the academic authorities in new stragetiges in library services organization i barrionuevo 97 reproduced with permission of the copyright owner. further reproduction prohibited without permission. relation to cooperation activities and the cooperative projects development, both as an answer to the need to reduce costs by sharing resources and as a means to face the growing and unstoppable demand from the users. the initiatives for the consortia organization are supported by highest academic level institutional agreements among the universities: principals and vice-principals of research (such is the case of the consortia of andalucia and madrid) or they are the result of initiatives taken by the autonomous government (galicia consortium) or a confluence of interests between the autonomous government and the universities (catalufla consortium). remote access to end users' information resources following the automation projects and the network technologies and data transmission development, most university libraries have made projects for all information resources integration and maintain a wide group of services: campuswide networks, catalogs, databases in cdrom (e .g., indice espanol de ciencias sociales y humanidades, indice espanol de ciencia y tecnologia, aranzadi legislaci6n y jurisprudencia, medline, abi inform, academic search) , e-mail , and remote access via internet. access to dll resources is available through the libraries management system opac web. there is access to any of these resources from any point connected to the network, whether from terminal servers, workstations, pcs, unix stations, or macs. i cooperation in spain up to the middle of the '80s, university libraries were separate realities with scattered funds and disorganized services; they were not structured as a system and they were lacking any tradition or mentality of cooperation. in a 1994 poll, only 40 percent of university library directors declared that cooperation among libraries was important. 4 we could say that the cooperation initiatives depend on the will of the people who obtain little support from the government. therefore, two different stages could be set: one in which cooperation is the result of personal actions, taken with no institutional support, in which local projects are undertaken ; or one in which individual initiatives are taken by the people in charge of libraries and a certain concern from the central government converge. will to share resources spain did not join the movement toward library automation until the '80s . at this time, the cooperative tenden98 information technology and libraries i june 2000 cies now associated with information and communication technologies were only slightly realized in the libraries. eventually, however, a consolidation of efforts took place, helping to bring about, at the end of the '80s and beginning of the '90s, some important cooperative initiatives out of which some specialized union catalogs could be brought. some of the first cooperative initiatives arose from the association of specialized libraries. 5 among these we can point out the coordinating committee of biomedical documentation, whose mission was to promote the cooperation and rationalization of document resources in the field of biomedicine. this committee holds conferences and maintains a union catalog of the daily publications on health services accessible through internet. 6 documat, created in 1988, groups together the libraries specializing in mathematics and maintains a union catalog of journals on which basis are organized plans of shared acquisition . mecano groups together the libraries of the schools of engineering and maintains a union catalog accessible through internet? early cooperative initiatives were also promoted by the library automation systems users groups. red universitaria espanola de dobis / libis began in 1990 when twelve universities using the system decide to create an online union catalog maintained by the university of oviedo. the libertas spanish users group maintains its union catalog associated with sls database, accessible online from bristol. rueca is the union catalog of absys users .8 need to cooperate in the early '80s a forum started in universities that attempted to influence the writing of the university statutes (as a result of the ley de reforma universitaria) and establish a general criterion for regulations. as a result of this debate, two documents have been published and have proved to be essential for subsequent cooperative development. 9 some reports from conferenc es on university libraries h eld in 1989 in the university complutense of madrid had a wide influence at the national level, and the same year, fundesco produced a report about the state-of-the-art in automation in the spanish university libraries .10 the situation that is repeated in these reports about th e libraries is extremely pessimistic. their evolution from 1985 to 1995 has been perfectly described by m. taladriz and l. anglada as "the lack of recognition of the role of university libraries ... the dispersion of bibliographical funds ... the general disorganization of the library services .... " 11 in 1988, red de bibliotecas universitarias (rebiun, university libraries network) was created. although inireproduced with permission of the copyright owner. further reproduction prohibited without permission. tially only nine university libraries were involved , the number grew to seventeen during the following years. the cooperative activiti es were centralized, and th ey obtained remarkable results in training, the improvement of library interlending, and in the publishing on cd-rom of bibliographical records from participant libraries. at the same time, and thanks to the celebration of the ifla congress in barcelona in 1993, the general need to create a wider discussion forum including all the univ ersity libraries and to obtain bett er cooperation and coordination was established. this idea crystallized with the creation of the conferencia de directores de bibliotecas universitarias y cientfficas (cobiduce, th e conference of university and scientific libraries directors). the first working mee ting was held in november 1993.12 this led to th e merging of rebiun with cobiduce in order to concentrate all the cooperation efforts into a single institution. a single institution, which kept th e name of rebiun, was created in 1996. in 1998, rebiun became the local committe e of the conferencia de rectores de las universidades espanolas (crue, conference of spanish university principals). rebiun has become the organization that oversees all the cooperation and coordination efforts in spanish academic librari es . rebiun activities include a union catalog published on cd-rom, "regulation s for university and scientific librari es," agreements on int erli brary loans, and activities in different working groups .13 i university libraries' consortia in the past few years the tran sfer of powers to the autonomous regions on ed u ca tion and culture, a consequence of a constitutional order, has brought about another political and administrative context for the achievement of the libraries ' objectives. th e autonomous regions are now working on the design of regional developm en t plans or regional information systems that are related, unfailingly, to the cooperative activity of the libraries of the territor y. thi s initiati ve can be applied to university librarie s as well as any other type of library , which, through their institutions, request their autonomous governments' assistance or funding in order to achieve cooperative projects. or it could be done the other way round: a governm ent can outline an action plan for its libraries and suggest it to the potential participants. thus, the basis for consortia development was set in the second half of the '90s, and encouraged by events like the celebrated conference in ca diz , organized by the university of carlos iii de madrid and the university of cadiz libraries , and ebsco information services (spanish branch) in 1998. catalonia consortium of university libraries (consorcio de bibliotecas universitarias de catalufia) we could sum up the situation in catalonia according to the following: the existenc e of new automated libraries, few automated records, the us e of their own automation systems, and the existence of only three universitie s. we can es tablish some cooperation background developed at this time : cruc, caps , and the joint selection of an automation system realiz ed by universidad aut6noma de barcelona and universidad politecnica de cataluna. it is not until the '90s that positive factors combined to move the cooperative movement a step forward in catalonia. these positive factors were a homogeneous s ta te of automation among university libraries, a good communications network, and the use of standards for library data recording . the previous cooperative movements and an analysis of the worldwide evolution of libraries helped in the building of a united view in which coop era tion appeared as an additional instrument for the improvement of the library world. the university library directors of catalonia considered cooperation a way to accelerate the evolution of libraries, to create new services, to facilitate changes, and to save expenses. with this conviction, they wrote a proproposal for the creat io n of a library network in catalonia , which in 1993 resu lted in the interconnection of the university librarie s in catalonia, followed in 1995 with the first steps toward the cre ation of the united catalog of the univer sities of catalonia. this catalog was fully operative in early 1996. at the end of 1996 th e univ ersity library consortium of catalonia (cbuc) was created with the task of improving library services through cooperation. 14 its objectiv es are: • to create new workin g too ls • to improve services • to build a digital librar y • to take better advantages of resources • to face together the changing role in libraries the cbuc comprises the university of barcelona , universidad autonoma de barcelona, the politechnical university of catalonia , pompeu fabra university , th e univ ersity of girona, the university of lleida, rovira i virg ili university, the university oberta of catalonia , and the library of catalonia. the direction of cbuc is determined by a board of representatives from each of th e institutions, an executive committee of six members, and a technical committee of librar y dir ectors. a staff of seven new stragetiges in library services organization i barrionuevo 99 reproduced with permission of the copyright owner. further reproduction prohibited without permission. runs the cbuc office, and different working groups audit active plans and study possible issues of concern. university libraries consortium of the madrid region (comunidad autonoma de madrid) the public university libraries, based in the madrid region (universidad de alcala, universidad carlos iii, universidad complutense, universidad politecnica, universidad rey juan carlos, and uiversidad nacional de educaci6n a distancia), are developing many cooperation programs with the following objectives: • to facilitate access to information resources • to improve the existing library services • to test and promote the use of information and communication technologies • to reduce costs by sharing resources 15 two programs have already been initiated: interlibrary loan. an agreement to obtain a faster delivery system for books and journal articles has been established. using the services of a private courier company, maximum delivery time from one university to another will be set to forty-eight hours. this service started working on the first of sepember. training. different courses for the joint training of library staff are being organized on a cooperative basis. in the future, other programs will be developed, including a union catalog (with the creation of a collective data basis that will also save cataloging costs by sharing bibliographical resources); and an elecronic library, which will allow common access to electronic resources. galician libraries consortium the galician libraries consortium is the result of a regional government intiative. 16 in november 1996 the xunta de galicia signed an agreement of scientific and technological collaboration with fijitsu icl spain in which the company agreed to develop the telecommunications infrastructure of the community: the galician information highway (agi: autopista gallega de la informaci6n). inaugurated in 1997, agi serves as the basis for projects with great political and social appeal. three projects were embarked upon : • tele-teaching, • tele-medicine, and • access to libraries users have access to a loan service by which a loan may be requested from any library in the consortium. the loan works as it would work in a local climate, with the same limitations, controls, and blocking of any other local loan system . the request to the system is sent online and is fulfilled within twenty-four to forty-eight hours. the consortium originally was to encompass all types of libraries, but as the project advanced, it was decided to restrict the collaboration to university libraries. this allowed the project to move forward with greater speed, because the member libraries had more narrowly defined interests and concerns. the xunta de galicia prepared the "protocol of intentions," which has been signed by the highest representatives of the three gallician universities (universidad de santiago, universidad de la corufta, and universidad de vigo). this protocol is characterized by two essential ideas: 1. allow adequate time for planning individual incorporation into the consortium, so that each institution may participate at the rate it deems appropriate. 2. create a permanent working commission formed by representatives of the institutions involved, which will: • answer existing and future questions; • define the model of consortium that each organization desires to establish through specific objectives; and • promote adequate measurement in order to obtain the objectives that have been designed . andalucian university libraries consortium in the era of the internet, electronic documents, and the virtual library, maintaining independent libraries is out of order . in addition, the efforts needed to face the challenges of the information society and the changes that society is demanding of universities are destined to become weaknesses more than strengths in those institutions that face them individually. there are many reasons why it is advisable for libraries to approach these challenges collaboratively: • the productivity and competitiveness that society demands of the universities • the huge technological opportunities to share information • the importance of the changes that are taking place in the products and services that the information market offers • the high cost of the new products (e.g., e-joumals) • the need of very specialized knowledge in order to activate some of these services • the growing demands of library users the andalucian university libraries concluded that if they wished to stay current with information technologies, if they wished to continue implementing improved services, and if they wished to do so within their budg100

be established. in march 1998 the andalucian vice-principals of research requested the directors of the andalucian university libraries to analyze possible cooperative activities among the university libraries of the community. two goals were set in this meeting: • the analysis of library automation products currently on the market. • the analysis of the current individual management systems within the andalucian libraries (which, though automation varied within them, were each considered to be outdated) and the potential for sharing resources with the present systems, which is difficult because currently available systems may not be compatible with z39.50. the object of this analysis is to define essential requirements so the new systems to be implemented facilitate possible cooperative actions. this possible integration will not be simple: the university pablo de olavide, recently created, is planning to purchase its own system; the universities of seville, granada, and cordoba are using dobis-libis; and the universities of cadiz and malaga are using libertas and are preparing to update to innopac. the andalucian university libraries have studied some of the systems that the spanish market offers: abys (baratz, document systems), amicus (elias), innopac (sls), sabini (sabini library automation) and unicorn (sirsi). they are preparing a catalog of electronic information resources available in the andalucian university libraries to know which resources are available and preferred by different universities. the andalucian university libraries consortium is in an early stage; while its organizational structure and functions are defined, its tasks are still being elaborated. the delegate commission of the vice-principals of research of the andalucian universities is responsible for this work. the commission is presided over by the viceprincipal of the university of seville and formed by the directors of the andalucian libraries and the juridical consultant of the university of cordoba. the commision will produce a working paper that outlines the main facets of the organization, based on the following general principles: • to add value to the computer net of research • to favor the use of technologies that contribute to the improvement of the production times and the designing of efficient processes • to apply scale economies: • in the purchase of products and services • in repetitive tasks and activities • to favor the use of information resources among the members of the andalusian universities and the society in general in order for the project to succeed, the following conditions must exist: • a homogeneous situation among the libraries in terms of regulations and technical instruments used in the description of materials, data format, and information interchange format; • the andalucian universities are connected with high speed optic fiber lines (32 mb); • the administrative framework is clearly defined; and • the responsible members of the andalusian university libraries are convinced that cooperation will improve substantially the quality of the library services in each university. additionally, the following advantages must result: • decline or leveling of production expenses • economies of scale in the purchase of products such as computer systems, databases, and journal and electronic information subscriptions • shared technical support • shared training costs • shared information resources through interlibrary loan i conclusions the ultimate goal of cooperation is to join users and the documents and information they need; establishing relations among participant institutions is a means to that end. consortia represent the possibility to test alternatives to the traditional automated library. they represent the potential to offer the best library services to a wider number of users with all the resources they possess. further than simple cooperation that unites efforts and resources, consortia represent the possibility to test innovative formulas of processes management and services organization from a regional perspective. references 1. miguel duarte, "evaluaci6n del

want heather howard, sarah huber, lisa carter, and elizabeth moore information technology and libraries | march 2018 8 heather howard (howar198@purdue.edu) is assistant professor of library science; sarah huber (huber47@purdue.edu) is assistant professor of library science; lisa carter (carte241@purdue.edu) is library assistant; and elizabeth moore (moore658@purdue.edu) is library assistant and student supervisor at purdue university. librarians from purdue university wanted to determine which social media platforms students use, which platforms they would like the library to use, and what content they would like to see from the library on each of these platforms. we conducted a survey at four of the nine campus libraries to determine student social media habits and preferences. results show that students currently use facebook, youtube, and snapchat more than other social media types; however, students responded that they would like to see the library on facebook, instagram, and twitter. students wanted nearly all types of content from the libraries on facebook, twitter, and instagram, but they did not want to receive business news or content related to library resources on snapchat. youtube was seen as a resource for library service information. we intend to use this information to develop improved communication channels, a clear social media presence, and a cohesive message from all campus libraries. introduction in his book tell everyone: why we share and why it matters, alfred hermida states, “people are not hooked on youtube, twitter or facebook but on each other. tools and services come and go; what is constant is our human urge to share.”1 libraries are places of connection, where people connect with information, technologies, ideas, and each other. as such, libraries look for ways to increase this connection through communication. social media is a key component of how students communicate with classmates, families, friends, and other external entities. it is essential for libraries to communicate with students regarding services, collections, events, library logistics, and more. purdue university is a large, land-grant university located in west lafayette, indiana, with an enrollment of more than forty thousand. the purdue libraries consist of nine libraries, presented collectively on the social media platforms facebook and twitter since 2009 and youtube since 2012. going forward, the purdue libraries want to ensure it establishes a cohesive message and brand that is communicated to students on platforms they use and on which they will engage with it. the purpose of this study was to determine which social media platforms the students are currently using, which platforms they would like the library to use, and what content they would like to see from the libraries on each of these platforms. mailto:howar198@purdue.edu mailto:huber47@purdue.edu mailto:carte241@purdue.edu mailto:moore658@purdue.edu academic libraries on social media | howard, huber, carter, and moore 9 https://doi.org/10.6017/ital.v37i1.10160 literature review academic libraries and social media academic libraries have been slow to accept social media as a venue for either promoting their services or academic purposes. a 2007 study of 126 academic librarians found that only 12 percent of those surveyed “identified academic potential or possible benefits” of facebook while 54 percent saw absolutely no value in social media.2 however, the mission of academic libraries has shifted in the last decade from being a repository of knowledge to being a conduit for information literacy; new roles include being a catalyst for on-campus collaboration and a facilitator for scholarly publication within contemporary academic librarianship.3 academic librarians have responded to this change, with many now believing that “social media, which empowers libraries to connect with and engage its diverse stakeholder groups, has a vital role to play in moving academic libraries beyond their traditional borders and helping them engage new stakeholder groups.”4 student perceptions about academic libraries on social media as the use of social media has grown with college-aged students, so has an increasing acceptance of academic libraries using social media to communicate. a pew research center report from 2005 showed just 7 percent of eighteen to twenty-nine year olds using social media. by 2016, 86 percent were using social media.5 in 2007 the oclc asked 511 college students from six different countries to share their thoughts on libraries using social networking sites. this survey revealed that “most college students would be unlikely to participate in social networking services offered by a library,” with just 13 percent of students believing libraries have a place on social media.6 however, just two years later (in 2009), a shift was seen: students were open to connecting with academic libraries, as observed in a survey of 366 freshmen at valparaiso university. when asked their thoughts on the library sending announcements and communications to them via facebook or myspace (a social media powerhouse at the time), 42.6 percent answered they would be “more receptive to information received in this way than any other response.” a smaller group, 12.3 percent, responded more negatively to this approach. students showed concern for their privacy and the level of professionalism, as a quote from a student illustrates: “facebook is to stay in touch with friends or teachers from the past. email is for announcements. stick with that!!!” 7 as students report becoming more open to academic libraries on social media, the question of whether they will engage through social media emerges. a recent study from western oregon university’s hammersley library asked this question with promising results. forty percent of students said they were either “very likely “or “somewhat likely” to follow the library on instagram and twitter, as opposed to wanting communications being sent to them directly through social media (for example, a facebook message). pinterest followed, with 33 percent of students saying they were either “very likely” or “somewhat likely” to follow the library using this platform.8 throughout the literature, students have shown an interest in information about the libraries that is useful to them. in another survey given to undergraduate students from three information technology classes at florida state university, one question examined the perceived importance of different library social media postings to students. the report showed students considered postings related to operations updates, study support, and events as the most important.9 in the hammersly study noted above, 78 percent and 87 percent of respondents said information technology and libraries | march 2018 10 they were either “very interested” or “somewhat interested,” respectively, in every category relating to library resources presented in the survey, but “interesting/fun websites and memes” received the least interest from participants.10 the literature shows an increase in students being receptive to academic libraries on social media. results vary campus to campus and students are leery of libraries reaching out to them via social media, but they have an increasingly positive view about content posted that will help them with the library. research questions the aim of this project was to investigate the social media behaviors of purdue university students as they relate to the libraries, and to develop evidence-based practices for managing the library’s social media accounts. the project focused on three research questions: 1. what social media platforms are students using? 2. what social media platforms do students want the library to use? 3. what kind of content do students want from the library on each of these platforms? methods we created the survey using the web-based qualtrics survey software. it was distributed in electronic form only, and it was promoted to potential respondents via table tents in the libraries, bookmarks at the library desk, facebook posts, and in-classroom promotion. potential respondents were advised that the survey was anonymous and voluntary. the survey consisted of closed questions, though many questions contained an open-ended field for answers that did not fall into the provided choices. inspiration for some of the options in our survey questions came from the hammersly library study, as we felt they did a good job capturing information about the social media usage of their patrons.11 our survey asked what social media platforms students use, what they use them for, how often they visit the library, how likely they are to follow the library on social media, which platforms they want the library to have, and what content they would like from the library on each of those platforms. the social media platforms included were facebook, flickr, g+, instagram, linkedin, pinterest, qzone, renren, snapchat, tumblr, twitter, youtube, and yik yak.12 there were also open-ended spaces where participants could write in additional platforms. the survey originally ran for three weeks in only the business library early in the spring 2017 semester, as its intended purpose was to inform how the business library would manage social media. after that survey was completed, we decided to replicate the survey in three additional libraries (humanities, social science, and education; engineering; and the main undergraduate libraries). this was done to expand the dataset and reach additional students in a variety of disciplines. these libraries were chosen because they were the libraries in which the authors work, with the hope to expand to additional libraries in the future. the second survey also lasted for three weeks starting in mid-april of the spring 2017 semester. as a participation incentive, students who completed the initial survey and the second survey had an opportunity to enter a drawing for a $25 visa gift card. academic libraries on social media | howard, huber, carter, and moore 11 https://doi.org/10.6017/ital.v37i1.10160 the survey was advertised across four different campus libraries and promoted in several ways to reach different populations. though the results are not from a random sample of the student population, the results are broad enough that we intend to apply them to our entire student population. results survey the survey was completed by 128 students. an additional 13 students began the survey but did not complete it; we removed their results from the analysis. the breakdown of respondents was 10 percent freshmen (n = 13), 22 percent sophomore (n = 28), 27 percent junior (n = 35), 20 percent senior (n = 25), and 21 percent graduate or professional (n = 27). library usage the students were asked how frequently they visit the library to determine if the survey was reaching a population of regular or infrequent library visitors. the results showed that the students who completed the survey were primarily frequent library users, with 93 percent (n = 119) visiting once a week or more. social media platforms the students were asked to identify which social media platforms they used and how frequently they used them. the most popular social media platforms were determined by combining the number of students who said they used them daily or weekly. the top five were facebook (n = 114, 88 percent), youtube (n = 102, 79 percent), snapchat (n = 90, 70 percent), instagram (n = 85, 66 percent), and twitter (n = 41, 32 percent). full results are in table 1. table 1. usage frequency by platform social media platform daily

percent, n = 51), snapchat (34 percent, n = 44), and youtube (29 percent, n = 37). full results can be seen in figure 2. after a student selected a platform they wanted the library to be on, logic built into the survey then directed them to an additional question that asked what content they would like to see from the library on that platform. content included library logistics (hours, events, etc.), research techniques and tips, how to use library resources and services, library resource info (database instruction/tips, journal availability, etc.), business news, library news (e.g., if the library wins an award), campus-wide info/events, and interesting/fun websites and memes. for facebook, students widely selected all types of content, with the most selections made for library logistics (n = 73) and the fewest made for business news (n = 33). for instagram, students wanted all content except business news (n = 18). snapchat was similar, except along with business news (n = 8), students also were not interested in receiving content related to library resource information (n = 9). twitter was similar to facebook in that all content was widely selected. youtube had a focus on library services, with the three most-selected content options being research techniques and tips (n = 20), how to use library resources and services (n = 19), and library resource info (n = 16).

everincreasing popularity with young adults, academic libraries have actively established a presence on several platforms.14 our survey shows that our students follow this trend, using social media regularly and for a variety of activities. we were surprised that facebook turned out to be the information technology and libraries | march 2018 16 most widely used by our students, as much has been written in the last few years about teens and young adults leaving the platform.15 a november 2016 survey, however, found that 65 percent of teens said they used facebook daily, a large increase from 59 percent in november 2014. though snapchat and instagram preferred, teens continue to use facebook for its utility in scheduling events or keeping in touch regarding homework.16 students do seem receptive to following the library on different platforms and report wanting primarily library-related content from us, including more in-depth content such as research techniques and database instruction. limitations and future work findings from this study give insight into opportunities for libraries to reach university students through social media. we acknowledge that only limited generalizations can be made because of the way the survey was conducted. our internal recruitment methods led to a selection bias in our surveyed population, as advertisement of the survey took place either in the chosen libraries or on the purdue libraries’ existing facebook page. because of this, our sample consists primarily of students who visit the library or already follow the library on facebook. we hope to alter this in future surveys by expanding our recruitment to other physical spaces across campus. in addition, we plan to add questions that first establish a better understanding of students’ opinions of libraries being on social media before asking what social media they would like to see libraries use. this would potentially avoid leading students to an answer. further, we are concerned we took for granted students’ understanding of library resources; that is, we may have made distinctions librarians understand, but students may not. in future studies, we plan to rephrase, and possibly combine, questions in a way that will be clear to people less familiar with library resources and services. we believe confusion with these questions created contradictory responses. for example, “research help through social media” received a low response rate, but “information on research techniques and tips” received a much higher response rate. additionally, a limitation of using a survey to collect behavior information is that respondents do not always report how they actually behave. using methods such as focus groups, interviews, text mining, or usability studies could provide a more holistic view of student behavior. duplication of this study on a yearly or semi-yearly basis across all libraries could help us see how social media preferences change over time and across a larger sample of our population. this study aimed to provide a broad view of a large university’s student body by surveying across different subject libraries. with the changes discussed, we think a revised survey could give us the detailed information we need to build a more effective social media strategy that reaches both library users and non-users. conclusion this study improved our understanding of the social media usage and preferences of purdue students. from these results, we intend to develop better communication channels, a clear social media presence, and a more cohesive message across the purdue libraries. under the direction of our new director of strategic communication, a social media committee was formed with representatives from each of the libraries to contribute content for social media. the committee will consider expanding the purdue libraries’ social media presence to communication channels where students have said they are and would like us to be. as social media usage is ever-changing, we recommend repeated surveys such as this to better understand where on social media students want to see their libraries and what information they want to receive from them. academic libraries on social media | howard, huber, carter, and moore 17 https://doi.org/10.6017/ital.v37i1.10160 references 1 alfred hermida, tell

column layout column title editor enterprise digital asset management (dam) systems are beginning to be explored in higher education, but little information about their implementation issues is available. this article describes the university of michigan’s investigation of managing and retrieving rich media assets in an enterprise dam system. it includes the background of the pilot project and descriptions of its infrastructure and metadata schema. two case studies are summarized—one in healthcare education, and one in teacher education and research. experiences with five significant issues are summarized: privacy, intellectual ownership, digital rights management, uncataloged materials backlog, and user interface and integration with other systems. u niversities are producers and repositories of large amounts of intellectual assets. these assets are of various forms: in addition to text materials, such as journal papers, there are theses, performances from per­ forming arts departments, recordings of native speakers of indigenous languages, or videos demonstrating surgical procedures, to name a few.1 such multimedia materials have not, in general, been available outside the originat­ ing academic department or unit, let alone systematically cataloged or indexed. valuable assets are “lost” by being locked away in individual drawers or hard disks.2 managing and retrieving multimedia assets are not problems confined to academia. media companies such as broadcast news agencies and movie studios also have faced this problem, leading to their adoption of digital asset management (dam) systems. in brief, dam systems are not only repositories of digital­rich media content and the associated metadata, but also provide management functionalities similar to database manage­ ment systems, including access control.3 a dam system can “ingest digital assets, store and index assets for easy searching, retrieve assets for use in many environments, and manage the rights associated with those assets.”4 in summer 2000, the university of michigan (u­m) tv station, umtv, was searching for a video archive solution. that fall, a u­m team visited cnn and experienced a “eureka!” moment. as james hilton, then­associate provost for academic, information, and instructional technology affairs, later wrote, “building a digital asset management into the infrastructure . . . will be the digital equivalent of bringing indoor plumbing to the campus.”5 in spring 2001, an enterprise dam system was considered for inclusion in the university infrastruc­ ture. upon completion of a limited proof­of­concept project, a cross­campus team developed the request for proposals (rfp) for the dams living lab, which was issued in july 2002 and subsequently awarded to ibm and ancept. in august 2003, hardware and software installation began in the living lab.6 by 2006, the project changed its name to bluestream to appeal to the grow­ ing mainstream user base.7 six academic and two support units agreed to partner in the pilot: ■ school of education ■ school of dentistry ■ college of literature, science, and the arts ■ school of nursing ■ school of pharmacy ■ school of social work ■ information technology central services ■ university libraries the academic units were asked to provide typical and unusual digital media assets to be included in the living lab pilot. the pilot focused on rich media, so the preferred types of assets were digital video, images, and other multimedia delivered over the web. the living lab pilot was designed to address four key questions: ■ how to create a robust infrastructure to process, manage, store, and publish digital rich media assets and their associated metadata. ■ how to build an environment where assets are eas­ ily searched, shared, edited, and repurposed in the academic model. ■ how to streamline the workflow required to create new works with digital rich media assets. ■ how to provide a campuswide platform for future application of rights declaration techniques (or other ip tools) to existing assets. this article describes the challenges encountered during the research­and­development phase of the u­m enterprise dam system project known as the living lab. the project has now ended, and the implemented project is known as bluestream. enterprise digital asset

kim, ahronheim, suzuka, king, bruell, miller, and johnson 5 ■ background of the living lab: u-m enterprise dam system project an enterprise project such as the living lab at u­m can have significant impact on an institution’s teaching and learning activities by allowing all faculty and students easy yet secure access to media assets across the entire campus. such extensive impact can only be obtained by overcoming numerous and varied obstacles and by docu­ menting actual implementation experiences employed to overcome those challenges. enterprise dam system vendors such as stellent, artesia, and canto list clients from many different industry sectors, including gov­ ernment and education, but provide no detailed case studies on their web sites.8 information regarding the status of enterprise dam system projects and specific issues that arose during implementation is difficult to find. information publicly available for enterprise dam system projects in higher education is usually in the form of white papers or proposals that do not cover the actual implementations.9 given the high degree of interest and the number of pilot projects announced in recent years, this shortcoming has prompted the writing of this article, which presents the most important lessons learned dur­ ing the first phase of the living lab pilot project with the hope that these experiences will be valuable to other academic institutions considering similar projects. as part of its core mission, u­m strives to meet the teaching and learning needs of the entire campus. thus, the living lab pilot solicited participation from a diverse cross­section of the university’s departments and units with the goal of evaluating the use of varied teaching and learning assets for the system. from the beginning, it was expected that this system would handle assets in many different forms, such as digital video or digitized images, and also accommodate various organizational schemas and metadata for different collections. this sets the u­m enterprise dam system apart from projects that focus on only one type of collection or define a large monolithic metadata schema for all assets. data were gathered through interviews with asset providers, focus groups with potential users, and a review of the relevant literature. a number of barriers were identified during the pilot’s first phase. while there were some technical barriers, the most signifi­ cant barriers were cultural and organizational ones for which technical solutions were not clear. perhaps the most significant cultural divide was between the culture of academia and the culture of the commercial sector. cultural and organizational assumptions from com­ mercial business practices were embedded in the design of the products initially used in the living lab imple­ mentation. thus, an additional implementation chal­ lenge was determining which issues should be resolved through technical means, and which should be solved by changing the academic culture. this is expected to be an ongoing challenge. ■ architecture (building the infrastructure) an enterprise dam system in an academic community such as u­m needs to support a wide variety of services in order to meet the numerous and varied teaching, research, service, and administrative functions. figure 1 illustrates the services that are provided by an enterprise dam system and concurrently demonstrates its com­ plexity. the left column, process, lists a few of the media processes that various producers will use prepare their media and subsequent ingestion into the enterprise dam system; the middle column, manage, demonstrates the various functions of the enterprise dam system; while the third column, publish, lists a subset of the publishing venues for the media. because an enterprise dam system supports a variety of rich media, a number of software tools and workflows are required. figure 2 illustrates this complexity and describes the architecture and workflow used to add a video segment. the organization of figure 2 parallels that of figure 1. the left column, process, indicates that flip factory by telestream is used to convert digital video from the original codec to one that can be used for play­ back.10 in addition, videologger by virage uses media analysis algorithms to extract key frames and time codes created by louis e. king, ©2004

the video as well as to convert the speech­to­text for easy searching.11 the middle column, manage, illustrates tools from ibm that help create rich media as well as tools from stellent, such as its ancept media server (ams), that store and index the rich media assets.12 the third column, publish, illustrates two examples of how these digital video assets could be made available to the end user. one strategy is as a real video stream using real network’s helix server, and the other as a quicktime video stream using ibm’s videocharger.13 a thorough discussion of all of the software and hardware that make up u­m’s dam system is beyond the scope of this article. however, a list of the software components with links to their associated web sites is provided in figure 3. from the beginning the living lab pilot aimed for a diverse collection of assets to promote resource discovery and sharing across the university. figure 4 illustrates how the living lab is expected to fit into the varied publishing venues that comprise the campus teaching and learning infrastructure. existing storage and network infrastruc­ tures are used to deliver media assets to various software systems on campus. the living lab is used to streamline the cataloging, searching, and retrieving processes encoun­ tered during academic teaching and research activities. the following example describes how the enterprise dam system fits into the future campus cyberinfrastruc­ ture. a faculty member in the school of music is a jazz composer. one of her compositions is digitally stored in the enterprise dam system along with the associated metadata (cataloging information) that will allow the piece to be found during a search. that single audio file is then found, accessed, and used by five unique publish­ ing venues—the course web site, the university web site, a radio broadcast, the music store, and the library archive. the faculty member uses the piece in her jazz interpreta­ tion course and thus includes a link to the composition on her sakai course web site.14 when she receives an award, the u­m issues a press release on the u­m web site that includes a link to an audio sample. concurrently, michigan radio uses the enterprise dam system to find the piece for a radio interview with her that includes an audio segment.15 her performance is published by block m records, u­m’s web­based recording label, and, lastly, the library permanently stores the valuable piece in its institutional archive, deep blue.16 ■ metadata (managing assets within the academic model) the vision for enterprise dam at u­m is for digital assets to not only be stored in a secure repository, but also be findable, accessible, and usable by the appropriate persons in the university community in their academic endeavors. information about these assets, or metadata, is a crucial component of fulfilling this vision. an important created by louis e. king, ©2004 regents of the university of

htm figure 3. software used in the living lab article title | author 7enterprise dam system pilot | kim, ahronheim, suzuka, king, bruell, miller, and johnson 7 question that arises is, “what kind of metadata should be required for the assets in the living lab?” to help answer this question, potential asset provid­ ers were interviewed regarding their current approach to metadata, such as if they used a particular schema and how well it met their purposes. not surprisingly, asset providers had widely varied metadata implementations. while the assets intended for the living lab pilot all had some metadata, the scope and granularity varied greatly. metadata storage and access methods also varied, ranging from databases implemented using commercial database products and providing web front­ends, to a combination of paper and spreadsheet records that had to be consulted together to locate a particular asset. the assets to be used in the living lab pilot consisted primarily of high­ and low­resolution digital images and digitized video. these interviews also generated a number of requirements for any potential living lab metadata schema. it was deter­ mined that the schema should be able to: ■ describe heterogeneous collections at an appropriate level of granularity and detail, allowing for domain­ specific description needs and vocabularies; ■ allow metadata entry by non­specialists; ■ enable searches across multiple subject areas and col­ lections; ■ provide provenance information for the assets; and ■ provide information on authorized uses of the assets for differing classes of users. an examination of the literature showed a general consensus that no single metadata standard could meet the requirements of heterogeneous collections.17 projects as diverse as pb core and vius at penn state adopted the approach of drawing from multiple existing metadata standards.18 their approaches differ in that pb core is a combination of selected metadata elements from a num­ ber of standards plus additional elements unique to pb core, while vius opted for a merged superset of all the elements in the standards selected. in interviews with asset providers (usually faculty), cataloging backlog and the lack of personnel for gen­ erating and entering metadata emerged as consistent problems. there was concern that an overly complex or specialized schema would aggravate the cataloging back­ log by making metadata generation time­consuming and cumbersome. budgetary constraints made hiring pro­ fessional metadata creators prohibitive. another aspect of the personnel problem was that adequate descrip­ tion required subject specialists who were, ideally, the resource authors or creators. but subject specialists, while familiar with the resources and the potential audience for them, may not be knowledgeable of how to produce high­quality metadata, such as controlled vocabularies or consistent naming formats. to address these issues, the more simple and straight­ forward indexing process offered by dublin core (dc) was selected as the starting point for the metadata schema in the living lab.19 dc was originally developed to sup­ port resource discovery of a digital object, with resource authors as metadata creators. dc is a relatively small standard, but is extensible through the use of qualifiers. it has been adopted as a standard by a number of standards organizations, such as iso and ansi. a body of research exists on its use in digital libraries and its efficacy for author­generated metadata, and there are metadata crosswalks between dc and most other metadata stan­ dards. a number of other subject­specific standards were also examined for more specialized description needs and controlled vocabularies: vra core, ims learning resource meta­data specification, and snodent.20 in the end, the project leaders elected to adopt a rather novel approach to metadata by not defining one metadata schema for all assets. by taking advantage of the power of multiple approaches (for example, pb core for mix­and­ match, and vius for a merged superset) each collection can have its own schema as long as it contains the ele­ ments of a more general, lowest­common­denominator schema. this overall schema, um_core, was defined based on dc. the elements are prefixed with dc or um to specify the schema origin. um_publisher and um_alternatepublisher identify who should be contacted about problems or ques­ tions regarding that particular asset. um_secondarysubject is a cross­collection subject classification

and libraries | december 20078 information technology and libraries | december 2007 oped by the u­m libraries, and helps map the asset into the context of the university. in adopting such an approach to metadata, metadata creation is seen not as a one­shot process, but a collaborative and iterative one. for example, on initial ingestion into the living lab, the only metadata entered for an image may be dc_title, dc_date, and um_publisher. additional meta­ data may be entered as users discover and use the asset, or as input from a subject specialist becomes available. the discussion so far has focused on metadata pro­ duced with human intervention. a number of metadata elements can be obtained from the digital objects through the use of software. in an enterprise dam system, this is referred to as automatically generated metadata and is what can be directly obtained from a computer file such as file name, file size, and file format. this type of metadata is expected to play a larger role as an increasing propor­ tion of assets will be born digital and come accompanied by a rich set of embedded metadata. for example, images or video produced by current digital cameras contain exchangeable image file format (exif) metadata, which include such information as image size, date produced, and camera model used. when available, the living lab presents automatically generated metadata to the user in addition to the elements in um_core. thus, asset metadata in the living lab can be pro­ duced in two ways: automatically generated through a tool such as virage videologger in the case of video, or entered by hand through the current dam system inter­ face.21 in addition, if metadata already exist in a database format, such as filemaker, this can be imported once the appropriate mappings are defined.22 videologger, a video analysis tool for digital video files, can extract video key frames, add closed captions, determine whether the audio is speech or music, convert speech to text, and identify (through facial recognition) the speaker(s). these capabilities allow for more sophis­ ticated searching of video assets compared to the cur­ rent capabilities of search engines such as google. some degree of content­based searching can now be done, as opposed to searching that relies on the title and other textual description provided separately from the video itself. for the pilot, particular interest was expressed in the speech recognition capability of videologger. videologger generates a time­coded text of spoken key­ words with 50 to 90 percent accuracy. the result is not nearly accurate enough to generate a transcript, but does indeed provide robust data for searching the content of video. given the diversity of assets in the living lab, it is clear that the university can utilize low­cost keyword analysis to enhance search granularity as well as the more expensive, fully accurate hand­processed transcript. ■ workflow examples two instructional challenges demonstrate how an enter­ prise digital asset management system can provide a solution to instructional dilemmas and how a unique workflow needs to be created for each situation. the chal­ lenges related to each project are described. school of dentistry the educational dilemma the u­m school of dentistry uses standardized patient instructors (spis) to assess students’ abilities to interact with patients. carefully trained actors play carefully scripted patient roles. dental students interview the patients, read their records, and make decisions about the patients’ care, all in a few minutes (see figure 6). each session is video recorded. currently, spis grade each student on predeter­ mined criteria, and the video recording is only used if a student contests the spis’ grade. ideally, a dental educator should review each recording and also grade each student. however, the u­m class size of 105 dental students causes a recording­based grading process to be prohibitively expensive in terms of personnel time. in addition, the use of digital videotape makes it difficult for the recorded sessions to be made available to the students. because the tapes are part of the student’s record, they cannot be checked out. if a student wants to review a tape, she or he must make an appointment and review it in a supervised setting. living lab solution the u­m school of dentistry’s living lab pilot attempted simultaneously to improve the spi program and lower the cost of faculty grading spi sessions through three goals: dc_title dc_creator dc_subject um_secondarysubject dc_description dc_publisher dc_contributor dc_date dc_type dc_format dc_identifier dc_source dc_language dc_relation dc_coverage dc_rights um_publisher um_alternatepublisher figure 5. the u-m enterprise dam system metadata scheme um_core article title | author 9enterprise dam system pilot | kim, ahronheim, suzuka, king, bruell, miller, and johnson 9 1. use speech­to­text analysis to create an easily searched transcript; 2. streamline the recording process; and 3. make the videos available online for student review. each of these challenges and the current results are summarized. speech-to-text analysis it was hypothesized that an effective speech­to­text anal­ ysis of the spi session could enable a grader quickly to locate video segments that: (1) represented student dis­ cussion of specific dental procedures; and (2) contained student verbalizations of key clinical communication skills.23 in summer 2005, nine spi sessions were recorded and a comparison between manual transcription and the automated speech­to­text processes was conducted. the transcribed audio track was manually marked up with time­coded reference points and inserted as an annota­ tion track to the video. those same videos also were ana­ lyzed through the video logger speech­to­text service in the living lab, resulting in an automatically generated, time­coded text track. lastly, six keywords were selected that, if spoken by the student, indicated the correct use of either a dental procedure or good communication skills. keyword searches were conducted on both the manual transcription and the speech­to­text analysis. three results were calculated on the key word searches of both versions of all nine recorded sessions. they were: (1) the number of successful keyword searches; (2) the number of successful search results that did not actually contain the keywords (false positives); and (3) the time required to complete the manual transcrip­ tion and text­to­speech analysis of the recordings. the results demonstrated that the speech­to­text analysis matched the manual transcription 20 to 60 percent of the time. also, the speech­to­text process resulted in a false positive less than 10 percent of the time. lastly, the time required to complete the speech­to­text analysis of a session was two minutes, while the average time required to complete a manual transcription of the same session was 180 minutes. while not perfect, the results are encouraging that manually transcribing the audio is no longer necessary. improvements are being made to the clinical environment and microphones so that a higher­quality recording is obtained. it is anticipated that those changes combined with improved software will improve the results of the speech­to­text analysis sufficiently so that automated keyword searches can be conducted for grading purposes. streamlining the recording process scale is a significant challenge to capturing 105 spi inter­ actions in a short amount of time. two to three weeks are required for the entire class of 105 students to complete a series of spi experiences, with as a many as four concur­ rent sessions at any given time. in summer 2006, it was decided to record 50 percent of one class. logistically, one camera operator could staff two stations simultane­ ously. the stations had to be physically close enough for a one­person operation, but not so close that audio from the adjacent session was recorded. the optimal distance was about thirty to thirty­five feet of separa­ tion. staggering the start times of each session allowed the camera operator to make sure each was started with optimal settings. since the results of the speech­to­text analysis were linked to the quality of the equipment used, two prosumer minidv cameras with professional quality microphones and tripods also were purchased. student availability an important strength of living lab is the ability to make the assets both protected and accessible. the current itera­ tion does not have an interface for user­created access con­ trol lists (acl), instead they need to be created by a systems administrator. once a systems administrator has created an acl, academic technology support staff can add or subtract people. to satisfy family educational rights and protection act regulations, a separate acl is needed for each student for the spi project.24 currently, the possibility of including the spi recordings and their associated transcriptions as ele­ ments of an eportfolio is being explored.25 in the meantime, students can use url references to include these videos and transcripts in such web­based tools as eportfolios and course management systems. discussion as the challenges of improving speech­to­text analysis, recording workflow, and user­created acls are overcome, the spi program will be able to operate at a new and previ­ ously unimagined level. a more objective keyword grad­ ing process can be instituted. students will be easily able to search through and review their sessions at times and locations that are convenient for them. living lab also will allow students to view their eportfolio of spi interactions and witness how they have improved their communica­ tion skills with patients. for the first time in healthcare education, a clinician’s communication skills, such as bedside or chairside manner, will be able to be taught and assessed using objective methods. school of education the challenge of using records of practice for research and professional education classroom documentation plays a significant role in educational research and in the professional education of teachers at the u­m school of education. collections of 10 information technology and libraries | december 200710 information technology and libraries | december 2007 videos capturing classroom lessons, small­group work, and interviews with students and teachers—as well as other classroom records, such as images of student work, teacher lesson plans, and assessment documents—are basic to much of the research that takes places in the school of education. however, there also is a large and increasing demand to use these records from real class­ rooms for educational purposes at the u­m and beyond, creating rich media materials for helping preservice and practicing teachers learn to see, understand, and engage in important practices of teaching. this desire to create widely distributed educational materials from classroom documentation raises two important challenges: first, there is the important challenge of protecting the identity of children (and, in some cases, teachers); and second, there is the difficult task of ensuring that the classroom records can be easily accessed by individuals who have permission to view and use the records while being inac­ cessible to those without permission. one research and materials development project at the u­m school of education has been exploring the use of living lab to support the critical work of processing classroom records for use in research and in educational materials, and the distribution and protection of class­ room records as they are integrated into teacher educa­ tion lessons and professional development sessions at the u­m and other sites in the united states. the findings and challenges of these efforts are summarized below. processing classroom records the classroom records used in the pilot were processed in three main ways, producing three different types of products: ■ preservation copies are high­quality formats of the classroom records with minimal loss of digital infor­ mation that can be read by modern computers with standard software. these files are given standardized filenames, cleaned of artifacts and minor irregu­ larities, and de­identified (that is, digitally altered to remove any information that could reveal the identity of the students and, in some cases, of the teachers). ■ working copies are lower­quality versions of the preservation copies that are still sufficient for print­ ing or displaying and viewing. trading some degree of quality for smaller file sizes and thus data rates, the working copies are easier for people to use and share. additionally, these files are further devel­ oped to enhance usability: videos are clipped and composited to feature particular episodes; videos also are subtitled, flagged with chapter markers (or other types of coding), and embedded with links for accessing other relevant information; images of stu­ dent and teacher work are organized into multipage pdfs with bookmarks, links, and other navigational aids; and all files are embedded with metadata for aiding their discovery and revealing information about the files and their contents. ■ distribution copies are typically similar in quality to the working copies but are often integrated into other documents or with other content; they are labeled with copyright information and statements about the limitations of use. they are, in many cases, edited for use on a variety of platforms and copy protected in small ways (for example, word and powerpoint files are converted to pdfs). the living lab was found to support this processing of classroom records in two important ways. first, the system allowed for the setup and use of workflows that enabled undergraduate students hired by the project to upload processed files into the system and walk through a series of quality checks, focused on different aspects of the products. so, for example, when checking the preservation copies, one person was assigned to check the preservation copy against the actual artifact to make sure everything was captured adequately and that the resulting digital file was named properly (“quality check 1”). another individual was assigned to make sure the content was cleaned up properly and that no identifying information appeared anywhere (“quality check 2”). and finally, a third person checked the file against the meta­ data to make sure that all basic information about the file was correct (“quality check 3”). files that passed through all checks were organized into collections accessible to project members and others (“organize”). files that failed along the way were sent back to the beginning of the workflow (the “drawing board”), fixed, and checked again (see figure 7). figure 6. a dental student interviewing an spi. article title | author 11enterprise dam system pilot | kim, ahronheim, suzuka, king, bruell, miller, and johnson 11 second, living lab allowed asset and collection development to be carried out collaboratively and itera­ tively, enabling different individuals to add value in dif­ ferent ways over time. undergraduate students did much of the initial processing and checking of the assets; skilled staff members converted subtitles into speech metadata housed within living lab; and, eventually, project faculty and graduate students will add other types of analytic codes and content specific metadata to the assets. distribution and protection of classroom records in addition to supporting the production of various types of assets and collections, the living lab supported the distribution and protection of classroom records for use in education settings both at u­m and other institutions. for example, almost fifteen hours of classroom videos from a third­grade mathematics class were made acces­ sible to and were used by instructors and students in the college of education at michigan state university. in a different context, approximately ten minutes of classroom video was made available to instructors in mathematics departments at brigham young university, the university of georgia, and the city college of new york to use in courses for elementary teachers. each asset (and its derivatives) housed within living lab has a url that can be embedded within web pages and online course­management systems, allowing for a great deal of flexibility in how and where the assets are pre­ sented and used. at the same time, each call to the server is checked and, when required, users are prompted to authen­ ticate by logging in before any assets are delivered. this has great potential for easily, seamlessly, and safely integrating living lab assets into a variety of web spaces. although this feature has indeed allowed for a great deal of flexibility, there were and continue to be challenges with creating an integrated and seamless experience for school of education students and their instructors. for example, depending on a variety of factors, such as user operating systems and web browser combinations, users might be prompted for multiple logins. additionally, the login for the living lab server can be quite unforgiving, locking out users who fail to login properly in the first few tries and providing limited communication about what has occurred and what needs to be done to correct the situation. discussion during the living lab pilot a number of workflow chal­ lenges were overcome that now allow numerous and varied types of media related to classroom records to be ingested into living lab, and derivatives created. this demonstrates that living lab is ready for complex media challenges associated with instruction. however, the next challenge of delivering easily and smoothly to others still remains. once authentication and authorization is con­ ducted using single sign­on techniques that allow users to access assets securely from living lab through other systems, assets will be able to be incorporated into web­ based materials and used to enhance the instruction of teachers in ways that have yet to be conceived. ■ privacy, intellectual property, and copyright during the course of the pilot, a number of issues emerged. among these were some of the most critical issues that institutions considering embarking on a similar asset man­ agement system need to address. these issues are: ■ privacy; ■ intellectual ownership and author control of materials; ■ digital rights management and copyright; ■ uncataloged materials backlog; and ■ user interface and integration with other campus systems. up to this point, enterprise dam systems had been developed and used primarily by commercial enterprises— for example, cnn and other broadcasting companies. using a product developed by and for the commercial sec­ tor brought to the fore the cultural differences between the academy and the commercial sector (see figure 8). the first three issues in the previous list are related to the differing cultures of commercial enterprise and academia. these issues are addressed below. the fourth and fifth issues are addressed in the section “other important issues.” privacy videos of medical procedures can be of tremendous value to students. in their own words, “watching is different from reading about it in a textbook.” but subjects have the right to retract their consent regarding the use of their images or treatment information for educational purposes. this creates a dilemma: if other assets have been cre­ ated using it, do all of them have to be withdrawn? for drawing board → quality check 1 → quality check 2 → quality check 3 → organize figure 7. living lab workflow 12 information technology and libraries | december 200712 information technology and libraries | december 2007 example, if a professor included an image from the univer­ sity’s dam system in a classroom powerpoint or keynote presentation, and subsequently included the presentation in the university’s dam system, what is the status of this file if the patient withdraws consent for use of her or his treatment information?26 when must the patient’s request be fulfilled? can it be done at the end of the semester, or does it need to be completed immediately? if the request must be fulfilled immediately, the faculty member may not have sufficient time to find a comparable replacement. waiting until the end of the semester helps balance patient privacy with teaching needs. in either case, files must be withdrawn from the enterprise dam system and links to those files removed. consent status and asset relationships must be part of the metadata for an asset to handle such situations. consideration must be given to associating a digital copy of all consent forms with the corresponding asset within an enterprise dam system. intellectual ownership and author control of materials authors’ rights, as recognized by the berne convention for the protection of literary and artistic works, have two components.27 one, the economic right in the work, is what is usually recognized by copyright law in the united states, being a property right that the author of the work can transfer to others through a contract. the other component—the moral rights of the author—is not explicitly acknowledged by copyright law in the united states and thus may escape consideration regarding ownership and use of intellectual property. moral rights include the right to the integrity of the work, and thus come into play in situations where a work is distorted or misrepresented. unlike economic rights, moral rights cannot be transferred and remain with the author. in a university setting, the university may own the economic right for a researcher’s work, in the form of copyright, but the researcher retains moral rights. the following incident illustrates what can happen when only property rights are taken into account. a digital video segment of a medical procedure was being shown as part of a living lab demo at a university it showcase. because the u­m held the copyright for that particular videotape, no problems were foreseen regarding its usage. a faculty member recognized the video as one she had cre­ ated several years ago and expressed great concern that it had been used for such a purpose without her knowledge or consent. the concern arose from the fact that video showed an outdated procedure. while the faculty member continued to use this video in the classroom, she felt this was different from having it available through the living lab. in the classroom, the faculty member alerted students to the outdated practices during the viewing, and she had full control over who viewed it. the faculty member felt she lost this control and additional clarification when the video became available through living lab. that is, her work was now misrepresented and her moral rights as an author were violated. digital rights management and copyright in the academic world, digital rights management (drm) is becoming a necessary component in disseminating intellectual products of all forms.28 however, at this time there are few standards and no technical drm solution that works for all media on all platforms. therefore, u­m has elected to use social rather than technical means of managing digital rights. the living lab metadata schema provides an element for rights statements, dc_rights. these metadata, combined with education of the univer­ sity community about copyright, fair use, and the highly granular access control and privileges management of the system, provide the community with the knowledge and tools to use the assets ethically. the university can establish rights declarations to use in the dc_rights field as standards are developed and prec­ edent is established in the courts. these declarations may include copyright licenses developed by the university legal counsel as well as those from the creative commons.29 current solution—access control lists a clear difference between the cultures of commercial enterprises and academia emerged regarding access to assets, administered through acls.30 an acl specifies commercial dam system model university dam system model assets held centrally federated ownership of assets access, roles, and privileges managed centrally distributed management of access, privileges and roles metadata frameworks— monolithic federated metadata schema agnostic user interface(s) re: privileges, ownership figure 8. differences between commerical and university uses of a dam system. article title | author 13enterprise dam system pilot | kim, ahronheim, suzuka, king, bruell, miller, and johnson 13 who is allowed to access an asset and how they can use it. in commercial settings, access to assets is centrally managed, while in academia, with its complex set of intellectual and copyright issues, it is preferable to have them managed by the asset holders. university users repeatedly asked for the ability to define acls for each asset in the living lab. currently, end users and support staff cannot define acls—only system administrators can create them. the middleware for user­defined acls has been fully developed, and the user interface for user­ defined acls will be made available in the next version. this capability is important in the academic envi­ ronment because the composition of group(s) of people requiring access to a particular asset is fluid and can span many organizational boundaries, both within and outside the university. a research group owning a collection of assets may want to restrict access for various reasons, including requirements set forth by an institutional review board (irb, a university group that oversees research projects involving human subjects), or regulations such as the health insurance portability and accountability act of 1996, which addresses patient health information privacy.32 the research group will want flexible access control, as research group members may collaborate with others inside and outside the university. the original irb approval may specify that confidentiality of the subjects must be maintained, and collected data, such as video or transcripts, can only be viewed by those directly involved in the research project and cannot be browsed by other researchers not involved in the study or the public at large. in another situation, a collection of art images may only be viewed by current students of the institution, thus requiring a different acl. this situation is still open to interpretation. some say patient consent regarding the use of information for instructional purposes cannot be withdrawn for the use of existing information at the home institution. they can only withdraw it for the use of future assets. others may feel that patients can withdraw permission for the use of their patient assets. other important issues uncataloged materials backlog what emerged from interviews and focus groups with content providers was that while there was no lack of assets they would like to see online, a large proportion of these assets had never been cataloged or even sys­ tematically labeled in some form. this finding may be attributed in part to the pilot focusing on existing assets that have previously not been available for widespread sharing—such as the files stored on faculty hard disks and departmental servers—only known to a favored few. owners or creators of these materials had not consciously thought about sharing these materials or making them available to others. librarians, in contrast, have devel­ oped systems and practices to ensure the findability of materials that enter the library. asset owners were more than willing to have the assets placed online, but did not have the time or resources to provide the appropriate metadata. hiring personnel to create the metadata is problematic, as there is a limit to the metadata that can be entered by non­experts, and experts often are scarce and expensive. for example, for a collection of oral pathology images of microscopic slides, a subject expert must provide the diagnoses, stain, magnification, and other information for each image. without these details, merely putting the slides online is of little value, but these metadata cannot be provided by laypeople. collaborative metadata creation, allowing multiple metadata authors and iterations, may be one solution to this problem. a number of studies indicate that both organiza­ tional support and user­friendly metadata creation tools are necessary for resource authors to create high­ quality metadata.33 some of the backlog may be resolved through development of tools aimed at resource authors. in addition, increased use of digital file formats with embedded metadata may contribute to reducing future backlog by requiring less human involvement in meta­ data creation. faculty need to be taught that metadata raises the value and utility of assets. as they come to understand the essential role metadata plays, they, too, will invest in its creation. user interface and integration with other systems an enterprise dam system has two basic types of uses: by producers and by users. producers tend to be digital media technologists who create the digital assets and ingest them into the enterprise dam system. the users are the faculty, students, and staff who use these digital assets in their teaching, learning, or research. the research and development version of the enter­ prise dam system, living lab, works well for digital asset producers, but not for the users of these digital assets. ingestion and accessing processes are quite complex and are not currently integrated with other campus systems, such as the online library catalog or the sakai­based, campuswide course management sys­ tem, ctools.34 digital producers who are comfortable with complex systems are able to ingest and access rich media. however, users have to log onto the enterprise dam system and navigate its complex user interface. the level of complexity of accessing the media can cre­ ate a barrier to adoption and use. if the level of complex­ ity for accessing the assets is too high for users, then the system also is too complex to expect users to contribute to the ingestion of digital assets. 14 information technology and libraries | december 200714 information technology and libraries | december 2007 in both student and faculty focus groups there was concern about the technical skills needed for faculty use of an enterprise dam system in the classroom. ideally faculty should be able to incorporate assets seamlessly from the enterprise dam system to their classroom mate­ rials, such as powerpoint or keynote presentations. then, the presentations created on their computers should dis­ play without glitches on the classroom system. obviously faculty members cannot be expected to troubleshoot in the classroom when display problems occur. if the enterprise dam system is perceived as difficult to use, or as requiring a lot of troubleshooting by the user, this will discourage adoption by the faculty. this creates additional demands on the enterprise dam system, and potential additional it staffing demands for the academic units wanting to promote enterprise dam system use. when a problem is experienced in the classroom, the departmental it support, not the enterprise dam system support team, will be the first to be called. ideally, an enterprise dam system should be linked to the campus it infrastructure such that users or con­ sumers do not interact with the dam system itself, but rather through existing academic tools, such as the library gateway, course management system, or departmental web sites. having to learn a new system could be a sig­ nificant barrier to use for many potential dam system users in academia. ■ conclusions and lessons learned the vision of a dam system that would allow faculty and students easy yet secure access to myriad rich media assets is extremely appealing to members of the academy. conducting the pilot projects revealed numerous techni­ cal and cultural problems to resolve prior to achieving this vision. the authors anticipate that other institutions will need to address these same issues before undertaking their own enterprise dam system. using commercial software developed in academia during the course of the living lab pilot, the differ­ ences between academia and the commercial sector proved to be a significant issue. assumptions about the organizational culture and work methods are built into systems, often in a tacit manner. in the case of the initial iteration of the living lab, these assumptions were those of the corporate world, the primary clients of the commercial providers as well the environment of the developers. u­m project participants, meanwhile, brought their own expectations based on the reality of their work environment in academia. universities do not have a strict hierarchical structure, with each aca­ demic unit and department having a great degree of local control. academia also has a culture of sharing, where teaching or research products are often shared with no payment involved, other than acknowledgment of the source. thus, there was a process of mutual edu­ cation and negotiation regarding what was and was not acceptable in the enterprise dam system implementa­ tion. this difference of cultures first manifested itself with acls. in the initial implementation, an acl could be defined only by a system administrator. this was a showstopper for the u­m participants, who thought that asset providers themselves would be able to define and modify the acl for any particular asset. a centralized solution with a single owner of the assets (the company), which is acceptable in the corporate environment, is not acceptable in a university environment, where each user is consumer and owner. defining who has access to an asset can be a complex problem in academia, since this access is a moving target subject to both departmental and institutional constraints. libraries and librarians the traditional role of libraries is one of preserving and making accessible the intellectual property of all of humanity. with each new advance in information tech­ nology, such as dam systems, the role of libraries and librarians continues to evolve. this pilot highlighted the role and value of librarians skilled in metadata develop­ ment and assignment. without their expertise and early involvement, there would have been no standard method of indexing assets, thus preventing users from finding useful media. also, the project reinforced two reasons for encouraging asset creators to assign metadata at the asset creation point instead of at the archival point. one, this ensures that metadata are assigned when the content expertise is available. it is very difficult for producers to assign metadata retrospectively, and the indexing information may no longer be available at the point of archive. two, metadata assignment at the point of asset creation helps to ensure consistent metadata assignment that lends itself to automated solutions at the time of archiving.35 thus, while their role in digital asset man­ agement systems continues to evolve, the authors predict that the librarians’ role will evolve around metadata, and that libraries will start to become the archive for digital materials. it is anticipated that librarians will work with technical experts to develop workflows that include the automated metadata assignment to help faculty routinely add existing and new collections of assets to the system. one example of such a role is deep blue at the university of michigan. deep blue is a digital framework for pre­ serving and finding the best scholarly and artistic work produced at the university. article title | author 15enterprise dam system pilot | kim, ahronheim, suzuka, king, bruell, miller, and johnson 15 production productivity new technical complexities emerge with each new asset collection added to the u­m system. new workflows as well as richer software features continue to be developed to meet newly identified integration and user interface needs. as the living lab experience advances, techni­ cal barriers are eliminated and new workflows auto­ mated. the authors anticipate that, eventually, automated workflows will allow faculty and staff to routinely use digital assets with a minimum of technical expertise, thus decreasing the personnel costs associated with the use of rich media. for the foreseeable future, however, techni­ cally knowledgeable staff will be required to develop these workflows and even complete a significant amount of the work. academic practice the more delicate and challenging issue is educating fac­ ulty on the value and power of digital assets to improve their research and teaching. dam is a new concept to fac­ ulty, and it will only become useful when integrated into their daily teaching and research. this will happen as fac­ ulty members become more knowledgeable and increase their comfort in the use of digital assets. the dental case study demonstrates that an improved student experience can be provided with such an asset management system, while the education case study demonstrates that a com­ plex set of authentic classroom materials can be orga­ nized and ingested for use by others. these case studies are only two examples of the unanticipated outcomes that result from the use of digital assets in education. the authors predict that as more unanticipated and innova­ tive uses of digital assets are discovered, these new uses will, in turn, lead to increased academic productivity—for example, teaching more without increasing the number of faculty, students teaching each other with rich media, small­group work, and project­based learning. the list of possibilities is endless. as the living lab evolved from a research and development project into the implementation project known as bluestream, it has become an actual classroom resource. this article described myriad issues that were addressed so that other institutions can embark on their own enterprise dam systems fully informed about the road ahead. the remaining technical issues can and will be resolved over time. the greatest challenges that remain are being discovered as faculty and students use bluestream to improve teaching, learning, and research activities. the success of bluestream specifically, and enterprise dam systems in general, will be determined by their successes and failures in meeting the needs of faculty and students. ■ acknowledgements the authors recognize that the living lab pilot program was conducted with

september 2018 50 colby lewis (colbyllewis@gmail.com), a second year master of science in information student at the university of michigan school of information, is winner of the 2018 lita/ex libris student writing award. abstract the last literature review of research on the existence of an open access citation advantage (oaca) was published in 2011 by philip m. davis and william h. walters. this paper reexamines the conclusions reached by davis and walters by providing a critical review of oaca literature that has been published since 2011 and explores how increases in open access publication trends could serve as a leveraging tool for libraries against the high costs of journal subscriptions. introduction since 2001, when the term “open access” was first used in the context of scholarly literature, the debate over whether there is a citation advantage (ca) caused by making articles open access (oa) has plagued scholars and publishers alike.1 to date, there is still no conclusive answer to the question, or at least not one that the premier publishing companies have deemed worthy of acknowledging. there have been many empirical studies, but far fewer with randomized controls. the reasons for this range from data access to the numerous potential “methodological pitfalls” or confounding variables that might skew the data in favor of one argument or another. the most recent literature review of articles that explored the existence (or lack thereof) of an open access citation advantage (oaca) was published in 2011 by philip m. davis and william h. walters. in that review, davis and walters ultimately concluded that “while free access leads to greater readership, its overall impact on citations is still under investigation. the large access -citation effects found in many early studies appear to be artifacts of improper analysis and not the result of a causal relationship.”2 this paper seeks to reexamine the conclusions reached by davis and walters in 2011 by providing a critical review of oaca literature that have been published since their 2011 literature review.3 this paper will examine the methods and conclusions provoking such criticisms and whether these criticisms are addressed in the studies. i will begin by identifying some of the top confounders in oaca studies, in particular the potential for self-archiving bias. i will then examine articles from july 2011, when davis and walters published their findings, to july 2017. there will be a few exceptions to this time frame, but the studies cited in figures 4 and 5 are entirely from this period. in addition to reviewing oaca studies since davis and walters’ march 2011 study, i will explore the implications of an oaca on the future of publishing and the role of librarians in the subscription process. as antelman points out in her association of college and research libraries conference paper, “leveraging the growth of open access in library collection decision making,” it is the responsibility of libraries to use the newest data and technology available to them in the interest of best serving their patrons and advancing scholarship.4 in connecting oaca mailto:colbyllewis@gmail.com the open access citation advantage | lewis 51 https://doi.org/10.6017/ital.v37i3.10604 studies and the potential bargaining power an oaca could bring libraries, i assess the current roles that universities and university libraries play in promoting (or not) oa publications and the implications of an oaca for researchers, universities, and libraries, and i provide suggestions on how recent research could influence the present trajectory. i conclude by summarizing what my findings tell us about the existence (or lack thereof) of an oaca, and what these findings imp ly for the future of library journal subscriptions and the publish-or-perish model for tenure. lastly, i will suggest some alternative metrics to citations that could be used by libraries in determining future journal subscriptions and general collection management. self-archiving bias and why it doesn’t matter the idea of a self-archiving bias is based upon the concept that, if faced with a choice, authors will always opt to make their best work more widely available. effectively, when open access is not mandated, these articles may be specifically chosen to be made open access to increase readership and, hypothetically, citations.5 this biased selection method has the potential to confound the results of oaca studies because of the intuitive notion that an author’s best work is much more likely to be cited than any of their other work. its effect is amplified by making this work available oa, but it prevents studies in which articles were self-archived from being able to convincingly claim that the citation advantage these articles received was due to oa and not to its inherent quality and subsequent likelihood to be cited anyway. in a 2010 study, gargouri et al. determined that articles by authors whose institutions mandated self-archiving (such as in an institutional repository [ir]) saw an oaca just as great for articles that were mandated to be oa as for articles that were self-selected to be oa.6 this by no means proves a causal relationship between oa and ca, but does counter the notion that self -archived articles are an uncontrollable confounder that automatically compromises the legitimacy of oaca studies.7 ottaviani affirms this conclusion in a 2016 study in which he writes, “in the long run better articles gain more citations than expected by being made oa, adding weight to the results reported by gargouri et al.”8 in short, claiming that articles self-selected for self-archiving irreparably confound oaca studies ignores the fact that these authors have accounted for the likelihood that articles of higher quality will inherently be cited more. as gargouri et al. put it, “the oa advantage [to self-archived articles] is a quality advantage, rather than a quality bias” (italics in original).9 gold versus green and their effect on oaca analyses many critics of oaca studies have argued that such studies do not distinguish between gold oa, green oa, and hybrid (subscription journals that offer the option for authors to opt-in to gold oa) journals in their sample pool, thus skewing the results of their studies. in fact, there are many acknowledged subcategories of oa, but for the purposes of this paper, i will primarily focus on gold, green, and hybrid oa. figure 1, provided by elsevier as a guide for their clients, distinguishes between gold and green oa.10 while the chart provided applies specifically to those looking to publish with elsevier, it highlights the overarching differences between gold oa and green oa. a comprehensive list of oa journals is available through the directory of open access journals (doaj) website (https://doaj.org/). https://doaj.org/ information technology and libraries | september 2018 52 figure 1. elsevier explains to potential clients their options for publishing oa with elsevier and the differences between publishing with gold oa versus green oa. the argument that not distinguishing between gold oa and green oa in oaca studies distorts study results primarily stems from the potential for skew in green oa journals. green oa journals allow authors to self-archive their articles after publication, but the articles are often not made full oa until an embargo period has passed. this problem was addressed in a recent study conducted by science-metrix and 1science, who manually checked and coded approximatively 8,100 top-level domains (tlds).11 it is important to note that this study was made available as a white paper on the 1science website and has not been published in a peer-reviewed journal. additionally, 1science is a company built on providing oa solutions to libraries, which means they have a vested interest in proving the existence of an oaca. however, just as publishers such as elsevier have a vested interest in a substantial oaca not existing, this should not prevent us from examining their data. for their study, 1science did not distinguish hybrid journals as being in a distinct journal category. critics, such as the editorial director of journals policy for oxford university press, david crotty, were quick to fixate on this lack of distinction as a means of discrediting the study.12 employees of elsevier were similarly inclined to criticize the study, declaring that it, “like many others [studies] on this topic, does not appear to be randomized and controlled.”13 however, archambault et al., acknowledging that their study “does not examine the overlap between green and gold,” have provided an extremely comprehensive sample pool, examining 3,350,910 oa papers published between 2007 and 2009 in 12,000 journals.14 this paper examines the notion that “the advantage of oa is partly due to citations having a chance to arrive sooner . . . and concludes that the purported head start of oa papers is actually contrary to observed data.” 15 the open access citation advantage | lewis 53 https://doi.org/10.6017/ital.v37i3.10604 in a more recent study published in february 2018, piwowar et al. examine the prevalence of oa and average relative citation (arc) based on three sample groups of one hundred thousand articles each: “(1) all journal articles assigned a crossref doi, (2) recent journal articles indexed in web of science, and (3) articles viewed by users of unpaywall, an open-source browser extension that lets users find oa articles using oadoi.”16 unlike the 1science study, piwowar et al. had a twofold purpose: to examine the prevalence of oa articles available on the web and whether an oaca exists based on their sample findings. i do not include their results in my literature review because of the dual focus of their study, although i do compare their results with those of archambault et al. and analyze the implications of their findings. bronze: neither gold nor green in their article, piwowar et al. introduce a new category of oa publication: bronze. if gold oa refers to complete open access at the time of publication, and green oa refers to articles published in a paywalled journal but ultimately made oa either after an embargo period or via an ir, bronze oa refers to oa articles that somehow don’t fit into either of these categories. piwowar et al. define bronze oa articles as “free to read on the publisher page, but without any clearly identifiable license.”17 however, as crotty points out in a scholarly kitchen article reflecting on the preprint version of piwowar et al.’s article, “bronze” already exists as an oa category, but has simply been called “public access.”18 while coining “bronze” as a new term for “public access” is helpful in connecting it to oa terms such as “green” and “gold,” it is not quite the new phenomenon it is touted to be. arc as an indication of an oaca both archambault et al. and the authors of the 1science paper provide the arc as a means of establishing a paper’s impact on the larger research community. 19 within their arc analyses, archambault et al. distinguish between non-oa and oa, within which they differentiate between gold and green oa (figure 2). piwowar et al. group papers by closed (non-oa) and oa, with the following oa subcategories: bronze, hybrid, gold, and green oa (figure 3). an arc of 1.0 is the expected amount of citations an article will receive “based on documents published in the same year and [national science foundation (nsf)] specialty.” 20 based on this standard, articles with an arc above or below 1.0 represent a citation impact that percentage above or below the expected citation impact of like articles. for example, an article with an arc of 1.23 has received 23 percent more citations than expected for articles of similar content and quality. this scale can be incredibly useful in determining the presence of a citation advantage, and it can enable researchers to determine overall ca patterns. information technology and libraries | september 2018 54 figure 2. research impact of paywalled (not oa) versus open access (oa) papers “computed by science-metrix and 1science using oaindx and the web of science.” archambault et al., “research impact of paywalled versus open access papers,” white paper, science-metrix and 1science, 2016, http://www.1science.com/1numbr/. critics’ fixation on the “randomized and controlled” nature of the 1science study ignores the fact that the authors do not claim causation. rather, their findings suggest the existence of an oaca when comparing oa (in all forms) and non-oa (in any form) articles (see figure 2). the authors ultimately conclude that “in all these fields, fostering open access (without distinguishing between gold and green) is always a better research impact maximization strategy than relying on strictly paywalled papers.”21 unlike archambault et al., piwowar et al. found that gold oa articles had a significantly lower arc, and that the average arc of all oa balances out to 1.18 because of the high arcs of bronze (1.22), hybrid (1.31), and green (1.33). however, both studies fou nd that non-oa (referred to by piwowar et al. as “closed”) articles had an arc below 1.0, suggesting a definitive correlation between oa (without specifying type) and an increase in citations. http://www.1science.com/1numbr/ the open access citation advantage | lewis 55

https://doi.org/10.7717/peerj.4375. six years and what has changed in oaca research between july 2011 and the publication of piwowar et al.’s work in february 2018, nine new oaca studies have been published in peer-reviewed journals. of these, five only look at the oaca in one field, such as cytology or dentistry. the other four are multidisciplinary studies, two of which are repository-specific and only use articles from deep blue and academia.edu, respectively. this is important to note because of critics’ earlier stated objections to the use of studies that are not randomized controlled studies. however, the deep blue study can still be considered a randomized controlled sample group because the authors are not self-selecting articles to upload to the repository as they are with academia.edu. rather, articles were made accessible through deep blue “via blanket licensing agreements between the publishers and the [university of michigan] library.”22 some of the field-specific studies use sample sizes that may not reflect a general oaca, but rather one only for that field, and in certain cases, only for a single journal. field-specific studies between july 2011 and july 2017, five field-specific studies were conducted to determine whether an oaca existed in those fields. i summarize the scope and conclusions of these studies in table 1. as you can see from the table, the article sample size vastly varied between studies, but that can likely be accounted for by considering the specific fields studied since there are only five major cytopathology journals and nearly fifty major ecology journals. piwowar et al. acknowledge this in their study, noting that the nsf assigns all science journals “exactly one ‘discipline’ (a high-level categorization) and exactly one ‘specialty’ (a finer-grained categorization).”23 the more deeply nested in an nsf discipline a subject is, the more specialized the field becomes and the fewer journals there are on the subject. this alone is reason not to extrapolate from the results of these studies and project their results on the existence of oaca across all fields. https://doi.org/10.7717/peerj.4375 information technology and libraries | september 2018 56 only two of these studies, those focused on an oaca in dentistry and ecology, can be cons idered truly randomized controlled studies. both the cytopathology and marine ecology studies chose a specific set of journals from which to draw their entire sample pool. while the dentistry and ecology studies can be considered randomized controlled in nature, they still only reflect the occurrence (or lack thereof) of an oaca in those specific fields. it would be irresponsible to allow the results from studies in a single field of a single discipline to represent oaca trends across all disciplines. therefore, it is surprising that elsevier employees use the dentistry study to make such a claim. hersh and plume write, “another recent study by hua et al (2016) looking at citations of open access articles in dentistry found no evidence to suggest that open access articles receive significantly more citations than non-open access articles.”24 the key phrase missing from the end of this analysis is in dentistry. one might question whether a claim about multidisciplinary oaca can effectively be extrapolated from a single-field analysis. the authors do, two sentences later, qualify their earlier statement by saying, “in dentistry at least, the type of article you publish seems to make a difference but not oa status.”25 that is indeed what this study seems to show, and is therefore a logical claim to make. likewise, the three empirical studies in table 1 show that, for those respective fields, oa status does correlate to a citation advantage. in the case of the ecology study, the authors are confident enough in their randomized controlled methodology to claim causation. 26 the ecology study is the most recently published oaca study, and its authors were able to learn from similar past studies about the necessary controls and potential confounders in oaca studies. with this knowledge, tang et al. determined that: by comparing oa and non-oa articles within hybrid journals, our estimate of the citation advantage of oa articles sets controls for many factors that could confound other comparisons. numerous studies have compared articles published in oa journals to those in non-oa journals, but such comparison between different journals could not rule out the impacts of potentially confounding factors such as publication time (speed) and quality and impact (rank) of the journal. these factors are effectively controlled with our focus on hybrid journals, thereby providing robust and general estimates of citation advantages on which to base publication decisions. 27 the open access citation advantage | lewis 57 https://doi.org/10.6017/ital.v37i3.10604

journals to provide, it is possible that this study may serve as an ideal model for future larger oaca studies across multiple disciplines. however, more field-specific hybrid journal studies will have to be conducted before determining if this model would be the most accurate method for measuring oaca across multiple disciplines in a single study. multidisciplinary studies the multidisciplinary oaca studies conducted since 2011 include a single randomized control study and three empirical studies (table 2). all these studies found an oaca; in the case of niyazov et al., an oaca was found specifically for articles posted to academia.edu. i included this study because it is an important contribution to the premise that a relationship exists between self selection and oaca. niyazov et al. highlight this point in the section “sources of selection bias in academia.edu citations,” explaining that “even if academia.edu users were not systematically different than non-users, there might be a systematic difference between the papers they choose to post and those they do not. as [many] . . . have hypothesized, users may be more likely to post their most promising, ‘highest quality’ articles to the site, and not post articles they believe will be of more limited interest.”28 to underscore this point, i refer to gargouri et al., who stated that “the oa advantage [to self archived articles] is a quality advantage, rather than a quality bias” (italics in original).29 again, it is unsurprising that articles of higher caliber are cited more and that making such articles more readily available increases the amount of citations they would likely already receive. similar to my conclusion in the field-specific study section, we simply need more randomized controlled studies, such as ottaviani’s, to determine the nature and extent of the relationship between oa and ca across multiple disciplines. conclusions critics of some of the most recent studies, specifically archambault et al. and ottaviani, have argued that authors of oaca studies are too quick to claim causation. while a claim of causation does indeed require strict adherence to statistical methodology and control of potential confounders, few of the authors i have examined actually claim causation. they recognize that the empirical nature of their studies is not enough to prove causation, but rather to provide insight into the correlation between open access and a citation advantage. in all their conclusions, these authors acknowledge that further studies are needed to prove a causal relationship between oa and ca. the recent work published by piwowar et al. provides a potential model for replication by other researchers, and ottaviani offers a replicable method for other large research institutions with non-self-selecting institutional repositories. alternatively, field-specific studies conducted in the style of tang et al. across all fields would serve to provide a wider array of evidence for the occurrence of field-specific oaca and therefore of a more widespread oaca. recent developments in oa search engines have created alternative routes to many of the same articles offered by subscriptions, but at a fraction (if any) of the cost. antelman proposed that libraries use an oa-adjusted cost per download (oa-adj cpd), a metric that “subtracts the downloads that could be met by oa copies of articles within subscription journals,” as a tool for negotiating the price of journal subscriptions.30 by calculating an oa-adj cpd, libraries could information technology and libraries | september 2018 60 potentially leverage their ability to access journal articles through means other than traditional subscription bundles to save money and encourage oa publication. while antelman suggests using oa-adj cpd as a leveraging tool when making deals with publishers for journals subscriptions, i suggest that libraries use the data-gathering methods of piwowar et al. via unpaywall to determine whether enough articles from a specific journal can be found oa via unpaywall. by using metrics such as those collected by piwowar et al. through unpaywall, the potential confounding variable of articles found through illegitimate means (such as scihub) is alleviated. instead, piwowar et al.’s metrics focus on tracking the percentage of material searched by library patrons that can be found oa through the unpaywall browser extension. according to unpaywall’s “libraries user guide” page, libraries “can integrate unpaywall into their sfx, 360 link, or primo link resolvers, so library users can read oa copies in cases where there's no subscription access. over 1000 libraries worldwide are using this now. ”31 ideally, scholars will also be more willing to publish papers oa, and institutions will be more supportive of providing the necessary costs for making publications oa. though the publish-orperish model still reigns in academia, there is great potential in encouraging tenured professors to publish oa by supplementing the costs through institutional grants and other incentives wrapped into a tenure agreement. perhaps through this model, as gargouri et al. have suggested, the longstanding publish-or-perish doctrine will give way to an era of “self-archive to flourish.”32 bibliography antelman, kristin. “leveraging

information (pii), but the rapid, widespread adoption of information technology and the internet have given rise to new privacy and security challenges. hypertext transport protocol secure (https) is a form of hypertext transport protocol (http) that enables secure communication over the public internet and provides a deterministic way to guarantee data confidentiality so that attackers cannot

rigorous and pervasive manner. this report is intended to shed light on the state of https implementation in libraries, and to suggest ways in which libraries can evaluate and improve application security so that they can better protect the confidentiality of pii about library patrons. introduction patron privacy is fundamental to the practice of librarianship in the united states (u.s.). libraries have historically made great efforts to ensure the confidentiality of personally identifiable information (pii), but the rapid, widespread adoption of information technology and the internet have given rise to new privacy and security challenges. the usa patriot act, the rollback of the federal communications commission rules prohibiting internet service providers from selling customer browsing histories without the customer’s permission, along with electronic surveillance efforts by the national security agency (nsa) and other government agencies, have further intensified privacy concerns about sensitive information that is transmitted over the public internet when patrons interact with electronic library resources through online systems such as an online public access catalog (opac). 1 hypertext transport protocol secure (https) is a form of hypertext transport protocol (http) that enables secure communication over the public internet and provides a deterministic way to guarantee data confidentiality so that attackers cannot eavesdrop on communications. https has been used to protect sensitive information exchanges (i.e., e-commerce transactions, user authentication, etc.). in practice, however, security exploits such as man-in-the-middle attacks have demonstrated the relative ease with which an attacker can transparently eavesdrop on or hijack http traffic by targeting gaps in https implementation. there is little or no evidence in the literature that libraries are aware of the associated vulnerabilities, threats, or risks, or that researchers have evaluated the use of https in library web applications. this report is intended to shed light on the state of https implementation in libraries, and to suggest ways in which libraries can evaluate and improve application security so that they can better protect the mailto:richardt@vmware.com mailto:tonia.sannicolas-rocca@sjsu.edu application level security in a public library |thomchick and san nicolas-rocca 108 https://doi.org/10.6017/ital.v37i4.10405 confidentiality of pii about library patrons. the structure of this paper is as follows. first, we review the literature on privacy as it pertains to librarianship and cybersecurity. we then describe the testing and research methods used to evaluate https implementation. a discussion on the results of the findings is presented. finally, we explain the limitations and suggest future research directions. literature review the research begins with a survey of the literature on the topic of confidentiality as it pertains to patron privacy; the impact of information technology on libraries; and the use of https as a security control to protect the confidentiality of patron data when it is transmitted over the public internet. while there is ample literature on the topic of patron privacy, there appears to be a lack of empirical studies that measure the use of https to protect the privacy of data transmitted to and from patrons when they use library web applications.2 the primal importance of patron privacy patron privacy has long been one of the most important principles of the library profession in the u.s. as early as 1939, the code of ethics for librarians explicitly stated, “it is the librarian’s obligation to treat as confidential any private information obtained through contact with li brary patrons.”3 the concept of privacy as applied to personal and circulation data in library records began to appear in the library literature not long after the passage of the u.s. privacy act of 1974.4 today, the american library association (ala) regards privacy as “fundamental to the ethics and practice of librarianship,” and has formally adopted a policy regarding the confidentiality of personally identifiable information (pii) about library users, which asserts, “confidentiality exists when a library is in possession of personally identifiable information about users and keeps that information private on their behalf.”5 this policy affirms language from the ala code of ethics, and states that “confidentiality extends to information sought or received and resources consulted, borrowed, acquired or transmitted including database search records, reference questions and interviews, circulation records, interlibrary loan records, information about materials downloaded or placed on ‘hold’ or ‘reserve,’ and other personally identifiable information about uses of library materials, programs, facilities, or services.” 6 with the advent of new technologies used in libraries to support information discovery, more challenges arise to protect patron privacy.7 the impact of information technology on patron privacy researchers have studied the impact of information technology on patron privacy for several decades. early research by harter and machovec discussed the data privacy challenges arising from the use of automated systems in the library, and the associated ethical considerations for librarians who create, view, modify, and use patron records.8 fouty addressed issues regarding the privacy of patron data contained in library databases, arguing that online patron records provide more information about individual library users, more quickly, than traditional paperbased files.9 agnew and miller presented a hypothetical case involving the transmission of an obscene email from a library computer, and an ensuing fbi inquiry, as a method of examining privacy issues that arise from patron internet use at the library.10 in addition, merry pointed to the potential for violations of patron privacy brought about by tracking of personal information attached to electronic text supplied by publishers.11 information technology and libraries | december 2018 109 the consensus from the literature, as articulated by fifarek, is that technology has given rise to new privacy challenges, and that the adoption of technology in the library has outpaced efforts to maintain patron privacy.12 this sentiment was echoed and amplified by john berry, former ala president, who commented that there are “deeper issues that arise from the impact of converting information to digitized, online formats” and critiqued the library profession for having “not built protections for such fundamental rights as those to free expression, privacy, and freedom.”13 ala affirmed these findings and validated much of the prevailing research in a report from the library information technology association, which concluded, “user records have also expanded beyond the standard lists of library cardholders and circulation records as libraries begin to use electronic communication methods such as electronic mail for reference services, and as they provide access to computer, web and printing use.”14 in more recent years, library systems have made increasing use of network communication protocols such as http and focus of the literature has shifted towards internet technologies in response to the growth of trends such as cloud computing and web 2.0. mavodza characterizes the relevance of cloud computing as “unavoidable” and expounds on the ways in which software-as-aservice (saas), platform as a service (paas), and infrastructure as a service (iaas) and other cloud computing models “bring to the forefront considerations about . . . information security [and] privacy . . . that the librarian has to be knowledgeable about.”15 levy and bérard caution that nextgeneration library systems and web-based solutions are “a breakthrough but need careful scrutiny” of security, privacy, and related issues such as data provenance (i.e., where the information is physically stored, which can potentially affect security and privacy compliance requirements). 16 protecting patron privacy in the “library 2.0” era “library 2.0” is an approach to librarianship that emphasizes engagement and multidirectional interaction with library patrons. although this model is “broader than just online communication and collaboration” and “encompasses both physical and virtual spaces,” there can be no doubt that “library 2.0 is rooted in the global web 2.0 discussion,” and that libraries have made increasing use of web 2.0 technologies to engage patrons.17 the library 2.0 model disrupts many traditional practices for protecting privacy, such as limited tracking of user activity, short-term data retention policies, and anonymous browsing of physical materials. instead, as zimmer states, “the norms of web 2.0 promote the open sharing of information—often personal information—and the design of many library 2.0 services capitalize on access to patron information and might require additional tracking, collection, and aggregation of patron activities.”18 as ala cautioned in their study on privacy and confidentiality, “libraries that provide materials over websites controlled by the library must determine the appropriate use of any data describing user activity logged or gathered by the web server software.”19 the dilemma facing libraries in the library 2.0 era, then, is how to appropriately leverage user information while maintaining patron privacy. many library systems require users to validate their identity through the use of a username, password, pin code, or another unique identifier for access to their library circulation records and other personal information.20 however, several studies suggest the authentication process itself spawns a trail of personally identifiable information about library patrons that must be kept confidential.21 there is discussion in the literature about the value of using https and ssl certificates to protect patron privacy and build a high level of trust with users, and general awareness about importance of encrypting communications that involve sensitive information, such as “payment for fines and fees via the opac” or when “patrons are required to enter personal application level security in a public library |thomchick and san nicolas-rocca 110 https://doi.org/10.6017/ital.v37i4.10405 details such as addresses, phone numbers, usernames, and/or passwords.”22 however, as breeding observed, many opacs and other library automation software products “don't use ssl by default, even when processing these personalization features.” 23 these observations call library privacy practices into question, and are concerning since “hackers have identified library ilss as vulnerable, especially when libraries do not enforce strict system security protocols.” 24 one of the challenges facing libraries is the perception that “a library's basic website and online catalog functions don't need enhanced security.”25 as a matter-of-fact, one of the most common complaints against https implementation in libraries has been: “we don’t serve any sensitive information.”26 these beliefs may be based on the historical practice of using https selectively to secure “sensitive” information and operations such as user authentication. but in recent years, it has become clear that selective https implementation is not an adequate defense. the electronic frontier foundation (eff) cautions, “some site operators provide only the login page over https, on the theory that only the user’s password is sensitive. these sites’ users are vulnerable to passive and active attacks.”27 passive attacks do not alter systems or data. during a passive attack, a hacker will attempt to listen in on communications over a network. eavesdropping is an example of a passive attack.28 active attacks alter systems or data. during this type of attack, a hacker will attempt to break into a system to make changes to transmitted or stored data, or introduce data into the system. examples of active attacks include man-in-the-middle, impersonation, and session hijacking.29 http exploits web servers typically generate unique session token ids for authenticated users and transmit them to the browser, where they are cached in the form of cookies. session hijacking is a type of attack that “compromises the session token by stealing or predicting a valid session token to gain unauthorized access to the web server,” often by using a network sniffer to capture a valid session id that can be used to gain access to the server.30 session hijacking is not a new problem, but the release of the firesheep attack kit in 2010 increased awareness about the inherent insecurity of http and the need for persistent https.31 in the wake of firesheep’s release and several major security breaches, senator charles schumer, in a letter to yahoo!, twitter, and amazon, characterized http as a “welcome mat for would-be hackers” and urged the technology industry to implement better security as quickly as possible.32 these and other events prompted several major site operators, including google, facebook, paypal, and twitter, to switch from partial to pervasive https. today these sites transmit virtually all web application traffic over https. security researchers from these companies, as well as from several standards organizations such as electronic frontier foundation (eff), internet engineering task force (ietf), and open web application security project have shared their experiences and recommendations to help other website operators implement https effectively.33 these include encrypting the entire session, avoiding mixed content, configuring cookies correctly, using valid ssl certificates, and enabling hsts to enforce https. testing techniques used to evaluate https implementation there is little or no evidence in the literature that libraries are aware of the associated vulnerabilities, threats, or risks, or that researchers have evaluated the use of https in library web applications. however, there are many methods that libraries can use to evaluate https and information technology and libraries | december 2018 111 ssl/tls implementation, including automated software tools and heuristic evaluations. these methods can be combined for deeper analysis. automated software tools among the most widely used automated analysis software tools is ssl server test from qualys ssl labs. this online service “performs a deep analysis of the configuration of any ssl web server on the public internet” and provides a visual summary as well as detailed information about authentication (certification and certificate chains) and configuration (protocols, key strength, cipher suites, and protocol details).34 users can optionally post the results to a central “board” that acts as a clearinghouse for identifying “insecure” and “trusted” sites. another popular tool is sslscan, a command-line application that, as the name implies, quickly “queries ssl services, such as https, in order to determine the ciphers that are supported.”35 however, these tools are limited in that they only report specific types of data and do not provide a holistic view of https implementation. heuristic evaluations in addition to automated software tools, librarians can also use heuristic evaluations to manually inspect the gray areas of https implementation, either to validate the results of automated software or to examine aspects not included in the functionality of these tools. one example is httpsnow, a service that lets users report and view information about how websites use https. httpsnow enables this activity by providing heuristics that non-technical audiences can use to derive a relatively accurate assessment of https deployment on any particular website or application. the project documentation includes descriptions of, and guidance for identifying, http-related vulnerabilities such as use of http during authenticated user sessions, presence of mixed content (instances in which content on a webpage is transmitted via https while other content elements are transmitted via http), insecure cookie configurations, and use of invalid ssl certificates. research methodology a combination of heuristic and automated methods was used to evaluate https implementation in a public library web application to determine how many security vulnerabilities exist in the application and assess to the potential privacy risks to the library’s patrons. research location this research project was conducted at a public library in the western us that we will call west coast public library (wcpl). this library was established in 1908 and employs ninety staff and approximately forty volunteers. in addition, it has approximately 91,000 cardholders. as part of its operations, wcpl runs a public-facing website and an integrated library system (ils) that includes an opac with personalization for authenticated users. test to conduct the test, a valid wcpl library patron account was created and used to authenticate one of the authors for access to account information and personalized features of wcpl’s opac. next, the google chrome web browser was used to visit wcpl’s public-facing website. a valid patron name, library card number, and eight-digit pin number were then used to gain access to online account information. several tasks were performed to evaluate https usage. a sample search application level security in a public library |thomchick and san nicolas-rocca 112 https://doi.org/10.6017/ital.v37i4.10405 query for the keyword “recipes” was performed in the opac while logged in. the description pages for two of the resources listed in the search engine result page (one printed resource and one electronic resource) were clicked on and viewed. the electronic resource was added to the online account’s “book cart” and the book cart page was viewed. during these activities, httpsnow heuristics were applied to individual webpages and to the user session as a whole. the web browser’s url address window was inspected to determine whether some or all pages were transmitted via http or https. the url icon in the browser’s address bar was clicked on to view a list of the cookies that the application set in the browser. each cookie was inspected for the text, "send for: encrypted connections only," which indicates that the cookie is secure. individual webpages were checked for the presence of mixed (encrypted and unencrypted) content. information about individual ssl certificates was inspected to determine their validity and encryption key length. all domain and subdomain names encountered during these activ ities were documented. the google chrome web browser was then used to access the qualys ssl server test tool. each domain name encountered was submitted. test results were then examined to determine whether any authentication or configuration flaws exist in wcpl’s web applications. results and discussion given the recommendations suggested by several organizations (e.g., eff, ietf, owasp), we evaluated wcpl’s web application to determine how many security vulnerabilities exist in the application, and assess the potential privacy risks to the library’s patrons. the results of tests, as discussed below, suggest that wcpl’s web application processes a number of vulnerabilities that could potentially be exploited by attackers and compromise the confidentiality of pii about library patrons. this is not surprising given the lack of research on https implementation, as well as the general consensus in the literature that technology adoption has outpaced efforts to maintain patron privacy. based on the results of these tests, wcpl’s website and ils span across several domains. some of these domains appear to be operated by wcpl, while others appear to be part of a hosted environment operated by the ils vendor. based on this information, it is reasonable to conclude that wcpl’s ils utilizes a “hybrid cloud” model. in addition, random use of https is observed in the opac interface during the testing process. this is discussed in the following sections. use of http during authenticated user sessions library patrons use wcpl’s website and opac to access and search for books and other material available through the library. given the results of the tests, wcpl does not use https pervasively across its entire web application. during the test, we found that wcpl’s website is transmitted via http by default. this was after manually entering in the url with an “https” prefix, which resulted in a redirect to the unencrypted “http” page. we continued to test wcpl’s website and opac by performing a query using the search bar located on the patron account page. we found that wcpl’s opac transmits some pages over http and others over https. for example, when a search query is performed in the search bar located on the patron account page, the search engine results page is sometimes served over https, and sometimes over http (see figure 1). this behavior is not limited to specific pages; rather it appears to be random. this security flaw leaves library patrons vulnerable to passive and active attacks that exploit gaps in https implementation, which allows an attacker to eavesdrop on and hijack a user-session providing the attacker with access to private information. information technology and libraries | december 2018 113 figure 1. results of the library’s use of https. presence of mixed content when a library patron visits a webpage served over https, the connection with the web server is encrypted, and therefore, safeguarded from attack. if an https webpage includes content retrieved via http, the webpage is only partially encrypted, leaving the unencrypted content vulnerable to attackers. analysis of wcpl’s website did not reveal any explicit use of mixed content on the public-facing portion of the site. test results, however, detected unencrypted content sources on some pages of the library’s online catalog. this, unfortunately, puts patron privacy at risk as attackers can intercept the http resources when an https webpage loads content such as an image, iframe or font over http. this compromises the security of what is perceived to be a secure site by enabling an attacker to exploit an insecure css file or javascript function, leading to disclosure of sensitive data, malicious website redirect, man-in-the-middle attacks, phishing, and other active attacks.36 insecure cookie management cookies are small text files, sent from a web server and stored on user computers via web browsers. cookies can be divided into two categories: session and persistent. persistent cookies are stored on the user’s hard drive until they are erased or expire. unlike persistent cookies, session cookies are stored in memory and erased once the user closes their browser. provided that computer settings allow for it, cookies are created when a user visits a website. cookies can be set up such that communication is limited to encrypted communication, and can be used to remember login credentials, previous information entered into forms, such as name, mailing address, email address, and the like. cookies can also be used to monitor the number of times a user visits a website, the pages a user visits, and the amount of time spent on a webpage. application level security in a public library |thomchick and san nicolas-rocca 114 https://doi.org/10.6017/ital.v37i4.10405 the results of the tests suggest that wcpl’s cookie policies are inconsistent. we found two types of cookies present. within one domain, the web application uses a jsession cookie that is configured to send for “secure connections only.” this indicates that the session id cookie is encrypted during transmission. another domain uses an asp.net session id that is configured to send for any connection, which means the session id could be transmitted in an unencrypted format. cookies transmitted in an unencrypted format could be intercepted by an attacker in order to eavesdrop on or hijack user sessions. this leaves user privacy vulnerable given the type of information contained within cookies. flawed encryption protocol support transport layer security (tls) is a protocol designed to provide secure communication over the web. websites using tls, therefore, provide a secure communication path between their web servers and web browsers preventing eavesdropping, hijacking, and other active attacks. this study employed the ssl server test from qualys ssl labs to perform an analysis of wcpl’s web applications. results of the qualys test (see figure 2) indicate that the site does not support tls 1.2, which means the server may be vulnerable to passive and active attacks, thereby providing hackers with access to data passed between a web server and web browser accessing the server. in addition, the application’s server platform supports ssl 2.0, which is insecure because it is subject to a number of passive and active attacks leading to loss of confidentiality, privacy, and integrity. figure 2. qualys scanning service results. the vulnerabilities discovered during the testing process may be a result of uncoordinated security. this is concerning because it is a by-product of the cloud computing approach used to operate wcpl’s ils. while libraries may have acclimated to the challenge of coordinating security measures across a distributed application, they now face the added complexity of coordinating information technology and libraries | december 2018 115 security measures with their vendors, who themselves may also utilize additional cloud-based offerings from third parties. as cloud technology adoption increases and cloud-based infrastructures become more complex and distributed, attackers will likely attempt to find and exploit systems with inconsistent or uneven security measures, and libraries will need to work closely with information technology vendors to ensure tight coordination of security measures. unencrypted communication using http affects the privacy, security, and integrity of patron data. passive attacks such as eavesdropping, and active attacks such as hijacking, man -in-the-middle, and phishing can reveal patron login credentials, search history, identity, and other sensitive information that, according to ala, should be kept private and confidential. given the results of the testing done in this study, it is clear that wcpl needs to revisit and strengthen their web application security measures by, according to organizations within the security community, using https pervasively across the entire web application, avoiding mixed content, configuring cookies limited to encrypted communication, using valid ssl certificates, and enabling hsts to enforce https. implementing improvements to https will mitigate attacks by strengthening the integrity of wcpl’s web applications, which in turn, will help protect the privacy and confidentiality of library patrons. limitations and future research this research was performed at a public library in the western u.s. therefore, future research is needed to study the implementation of https to increase patron privacy at other public libraries, libraries in other parts of the u.s. and in other countries. it would also be valuable to conduct similar research at libraries of different types, including academic, law, medical, and other types of special libraries. ssl server test from qualys ssl labs and httpsnow were used to evaluate the use of https at wcpl. the use of other evaluation techniques may generate different results. while a major limitation of this study is the evaluation of a single public library and the implementation of https to ensure patron privacy, a next phase of research should further investigate the policies in place that are used to safeguard patron privacy. these include security education, training, and awareness programs, as well as access controls. furthermore, library 2.0 and cloud computing are fundamental to libraries, but create risks that could impact the ability to keep patron pii safeguarded. as such, future research should evaluate the impact library 2.0 and cloud computing applications have on maintaining the confidentiality of patron information. conclusion the library profession has long been a staunch defender of privacy rights, and the literature reviewed indicates strong awareness and concern about the rapid pace of information technology and its impact on the confidentiality of personally identifiable information about library patrons. much work has been done to educate librarians and patrons about the risks facing them and the measures they can take to protect themselves. however, the research and experimentation presented in this report strongly suggest that there is a need for wcpl and other libraries to reassess and strengthen their https implementations. https is not a panacea for mitigating web application risks, but it can help libraries give patrons the assurance of knowing they take security and privacy seriously, and that reasonable steps are being taken to protect them. finally, this report concludes that further research on library application security should be conducted to assess the overall state of application security in public, academic, and special libraries, with the application level security in a public library |thomchick and san nicolas-rocca 116 https://doi.org/10.6017/ital.v37i4.10405 long-term objective of enabling ala and other

abstract exam period can be a stressful time for students, and having examples of past papers to help prepare for the tests can be extremely helpful. it is possible that past exams are already shared on your campus—by professors in their specific courses, via student unions or groups, or between individual students. in this article, we will go over the workflows and infrastructure to support the systematic collection, provision of access to, and repository management of past exam papers. we will discuss platform-agnostic considerations of opt-in versus opt-out submission, access restriction, discovery, retention schedules, and more. finally, we will share the university of toronto setup, including a dedicated instance of dspace, batch metadata creation and ingest scripts, and our submission and retention workflows that take into account the varying needs of stakeholders across our three campuses. background the university of toronto (u of t) is the largest academic institution in canada. it spans across three campuses and serves more than 90,000 students through its 700 undergraduate and 200 graduate programs.1 the university of toronto structure is the product of its rich history and is thus largely decentralized. as a result, the management of undergraduate exams is carried out individually by each major faculty at the downtown (st. george) campus, and centrally at the university of toronto mississauga (utm) campus and the university of toronto scarborough (utsc) camp us. the faculty of arts and science (fas) at the st. george campus has traditionally made exams from its departments available to students. in the pre-internet era, students were able to consult print and bound exams in departmental and college libraries’ reference collections. with the rise of online technologies, the fas registrar’s office seized the opportunity to make access to past exams more equitable for students and worked with the university of toronto libraries (utl) information technology services (its) to digitize and make exams available online. they were initially shared electronically via the gopher protocol and later via docutek eres, one of the first available course e-reserves systems. after the utl became an early adopter of the dspace (https://duraspace.org/dspace/) open source platform for its institutional repository in 2003, the utl its created a separate instance of dspace to serve as a repository of old exams. the repository makes the last three years of exams from the fas, utm, and utsc available online in pdf. about 5,500 exam papers are available to students with u of t login at any given time. discussed below are some of the considerations in establishing and maintaining a repository of old exams on campus, along with practical recommendations and shared workflows from the utl. mailto:mariya.maistrovskaya@utoronto.ca mailto:rachel.wang@utoronto.ca https://duraspace.org/dspace/ information technology and libraries march 2020 creating and managing a repository of past exam papers | maistrovskaya and wang 2 considerations in establishing a repository of old exams if you are looking to establish a repository of old exams, these are some of the considerations to take into account when planning a new service or evaluating an existing one. the source of old exams depending on the level of centralization on your campus, exams may be administered by individual academic departments or submitted by instructors/admins into a single location and managed centrally. the stakeholders involved in this process may include the office of the registrar, campus it, departmental admins or libraries, etc. establishing a relationship with such stakeholders is key in getting access to the files. when arranging to receive electronic files, consider whether they could be accompanied with existing metadata. alternatively, if the university archives or records management already receive copies of campus exams, you may be able to obtain them there. print versions will need to be digitized for online access—later in this article we will share metadata creation strategies in this scenario. it is also possible that exams may be collected in less formal ways, for example, via exam drives by student unions and groups. the utl works closely with the fas registrar’s office to receive a batch of exams annually. the utl receives a copy of print fas exams that get digitized by the its staff. the utl also receives exams from two u of t campuses, utm and utsc, that arrive in electronic format via the campus libraries. the u of t engineering society and the faculty of law each maintain their individual exam repositories, and the arts and science student union maintains a bank of term tests donated by students. content hosting and management one of the key questions to answer is which campus department or unit will be responsible for hosting the exams, managing content collection, processing and uploads, and providing technical and user support. these responsibilities may be within the purview of a single unit or may be shared between stakeholders. here are some examples of the tasks to consider: 1. collecting exams from faculty or receiving them from a central location 2. managing restrictions (exams that will not be made available online) 3. digitizing exams received in print 4. creating metadata or converting metadata received with the files 5. uploading exams to the online repository 6. removing exams from the online repository 7. providing technical support and maintenance (e.g., platform upgrades, troubleshooting) 8. providing user support (e.g., assistance with locating exams) at u of t, tasks 1–2 are taken care of by registrar offices at fas and utm and by the library at utsc. tasks 3–8 are performed centrally by the utl its, with the exception of digitization services for exams received from the utm and utsc campuses. further details and considerations related to the content management system and processing pipelines are outlined in the “infrastructure and workflows” section below. information technology and libraries march 2020 creating and managing a repository of past exam papers | maistrovskaya and wang 3 collection scope depending on the sources of your exams, you may need to establish the scope rules for what gets included in the collection. for example: • will you only include final exams? will term tests also be included? • will solutions be posted with the exams? • will additional materials, such as course syllabi, also be included? at the utl, only final exams are included in the repository, and no answers are supplied. exam retention making old exams available online is always a balancing act between the interests of students who want to have access to past test questions and the interests of instructors who may have a limited pool of questions to draw from or who may teach different course content over time and want to ensure that the questions continue to be relevant. at the utl, in consultation with campus partners, the balance was achieved by only posting the three most recent years of exams in the repository. as soon as a new batch is received, the utl removes a batch of exams more than three years old. opt-in versus opt-out approach where exam collection is driven centrally by a registrar’s office, for example, that office may require that all past exams be made available to students. similarly to the retention considerations, the needs of instructors who draw questions from a limited pool can be accommodated via opt-outs, individual exam restrictions, and ad hoc take-down requests. an alternative approach to exam collection would be an opt-in model where faculty choose to submit exam questions on their own schedule. at the utl, the fas and the utm campus both operate under the opt-out model. the utl receives all exam questions in regular batches unless they have been restricted by instructors’ requests. occasional withdrawal requests from instructors require an approval from the registrar’s office. conversely, the utsc campus operates under the opt-in model where individual departments submit their exams to the library. while this model provides the most flexibility, the volume of exams received from this campus is subsequently relatively small. repository access when making old exams available online, one of the things to consider is who will have access to them. will the exams only be available to students of the respective academic department, or to all students, or to the general public? will access be possible on campus as well as off campus? if the decision is made to restrict access, is there an existing authorization infrastructure in place that the repository could take advantage of, such as an institutional single sign-on or library’s proxy access? at the utl, access to the old exams repository is provided through ezproxy in the same fashion as subscription resources made available via the library. information technology and libraries march 2020 creating and managing a repository of past exam papers | maistrovskaya and wang 4 discoverability and promotion how will students find out about the exams available in the repository? will the repository be advertised via the library’s website, promoted by course instructors, or linked with the other course materials? considering the challenge of promoting a resource like this along with a variety of other library resources, it will be preferable to make it known to students via the same channels through which they receive other course information. for many institutions this would be via their learning management system or their course information system. at u of t, the old exams repository is linked from the library website. previously, the link was embedded in the university’s learning management system course template. with a recent transition to a new learning management engine, such exposure is yet to be reestablished. infrastructure and workflows minimum cms requirements a repository of old exams does not require a specific content management system (cms) or an offthe-shelf platform. your institution may already have all the components in place to make it happen. here are the minimum requirements you will want to see in such a system: • file upload by staff (preferably in batch) • file download by end users • basic descriptive metadata • search / browse interface • access control / authentication (if you choose to restrict access) the utl uses a stand-alone instance of dspace for its old exams repository. dspace is an opensource software for digital repositories used across the globe primarily in academic institutions. the utl chose this platform since it was already running an instance of dspace for its institutional repository (ir) and had the infrastructure and expertise on site. however, this is not a solution we would recommend to an institution with no existing dspace experience. while dspace is an open source platform, maintaining it locally requires significant staff expertise that may not be warranted considering that a collection of exams would only use a fraction of its robust functionality. if you do consider using dspace, a hosted solution may be preferable in a situation when local it resources and expertise are limited. distributing past exams via an existing digital repository an institution that already maintains a digital repository may consider adding exams as a collection to the existing infrastructure. when choosing to do so it is important to consider whether the exams use case may be different from your ir use case, and whether the new collection will fit in the existing mission and policies. differences may include the following: • access level. ir missions tend to revolve around providing openly accessible materials, whereas exams may need to be restricted. will your repository allow selective access restrictions to the exams collection? • longevity. ir materials are usually intended to be kept long-term, whereas exams may be on a retention schedule. for that reason, it also does not make sense to assign permanent identifiers to exams as many repositories do for their other materials. information technology and libraries march 2020 creating and managing a repository of past exam papers | maistrovskaya and wang 5 • file types and metadata. unlike a variety of research outputs and metadata usually captured in an ir, exams would have uniform metadata and object type. this makes them suitable for batch transformations and uploads. batch metadata creation options because of the uniform object type, exams are well suited to batch processing, transformations, and uploads. at utl, metadata is created from the filenames of scanned pdf files by a python script.2 the script breaks up the filename into dublin core metadata fields based on the pattern shown in figure 1. see figure 2 for a snippet of the script populating dublin core metadata fields. figure 1. file-naming pattern for metadata creation at utl. figure 2. a screenshot of the utl script generating dublin core metadata from filenames. once metadata is generated, the second python script (figure 3) packages the pdf and metadata file into a dspace simple archive (dsa) which is the format that dspace accepts for batch ingests. information technology and libraries march 2020 creating and managing a repository of past exam papers | maistrovskaya and wang 6 figure 3. a screenshot of the utl script packaging a pdf and metadata into a dspace simple archive. the dspace simple archive (dsa) then gets batch uploaded into the respective campus and examperiod collections (figure 4) using the dspace native batch import functionality. figure 5 shows what an individual exam record looks like in the repository. after a new batch is uploaded, collections older than three years are removed from the repository. the utl’s exams processing scripts are openly available in github under an apache license 2.0 (https://github.com/utlib/dspace-exams-ingest-scripts/). figure 4. a screenshot of collections in the utl’s old

7 figure 5. a screenshot of a record in the utl’s old exams repository. conclusion having access to examples of past exam questions can be extremely helpful to students in preparing for upcoming tests. it is possible that old exams are already being shared on your campus in official or unofficial ways, in print or electronically. facilitating online sharing of electronic copies means that all students, on and off campus, will have equitable access to these valuable resources. we hope that the considerations and workflows outlined in this article will help institutions establish such services locally. acknowledgements the authors would like to acknowledge the utl librarians and staff who contributed to the setup and maintenance of the old exams repository over the years: marlene van ballegooie, metadata technologies manager, who operated the filename-to-dublin core metadata crosswalk; sean xiao zhao, former applications programmer analyst, who converted it into python; and sian meikle, associate chief librarian for digital strategies and technology, who was at the inception of the original exam-sharing service and provided valuable historical context and feedback on

2000; 19, 2; proquest pg. 61 electronic library for scientific journals: consortium project in brazil making information available for the acquisition and transmission of human knowledge is the focal point of this paper, which describes the creation of a consortium for the 1111iversity and research institute libraries in the state of sao paulo, brazil. through sharing and cooperation, the project will facilitate information access and minimize acquisition costs of international scientific periodicals, consequently increasing user satisfaction. to underscore the advantages of this procedure, the objectives, management, and implementation stages of the project are detailed, as submitted to the research support foundation of the state of sao paulo (fapesp). i production, organization, and acquisition of knowledge in 1851, predicting the imminent growth in information, which in fact exploded in volume one hundred years later, joseph henri of the smithsonian institute voiced his opinion that the progress of mankind is based on research, study, and investigation, which generate wisdom, knowledge or, simply , information. he stated that for practically every item of interest there is some record of knowl edge pertinent to it, "and unless this mass of information be properly arranged, and the means furnished by which its content may be ascertained, literature as well as science will be overwhelmed by their own unwieldy bulk. the pile will begin to totter under its own weight, and all the additions we may heap upon it will tend to add to the extension of the base, without increasing the elevation and dignity of the edifice." 1 at the threshold of the twenty-first century, these words become more self-evident by the day. there are enormous archives of knowledge from which people extract parts, allowing them to advance and progress in science, technology, and the humanities. until some decades back, recovery from these archives was essentially a manual task consisting of written work and organization. today's technologies provide auxiliary tools to transmit this knowledge . although information is a cultural and social asset, it now is purchased at high prices . making these enormous archives available in a clear and organized manner by using the proper technology is currently the greatest challenge for all those involved in knowledge management-the production , organization, and transmission of information. rosaly favero krzyzanowski rosane taruhn i the advent and implications of electronic publications among the major contributions of the industrial era, outstanding are the evolution and growth of information publi shing and printing facilities that use tools to record, store, and distribute information. in the last ten years, the first steps were taken toward the storage and reproduction of sounds and images in new multimedia formats. technological advances also have brought new possibilities in accessing and disseminating information . electronic publishing has been particularly effective in accelerating access and contributing to the generation of additional knowledge; consequently, an exponential increase in data has taken place, most notably in the second half of the twentieth century. current journals numbered about 10,000 at the beginning of the century; by the year 2000 the number had reached an estimated 1 million. 2 as a result, specialized literature has been warning about a possible crisis in the traditional system of scientific publications on paper . in addition to the difficulty of financing the publication of these works, the prices of subscriptions to scientific periodicals on paper have been rising every year. at times, this makes it impracticable to update collections in all libraries, which interferes substantially in development. on the other hand, access to electronic scientific publications via internet is proving to be an alternative for maintaining these collections at lower cost. it also provides greater agility in publishing and distributing the periodical, and in the final user's accessing of the information. due to this, it is important that institutions that wish to support and promote research developed by their scientific communities facilitate access to these publications on electronic media . to paraphrase line, we can say that although publishers are still uncertain as to all the aspects of transmitting information electronically, because authors and institutions will be increasingly able to distribute their works on the web without the direct involvements of publishers, there is an escalation in electronic publications being published by scientific publishers.3 rosaly favero krzyzanowski is technical director of the integrated library system of the university of sao paulosibi/usp, brazil. rosane taruhn is director of the development and maintenance of holdings service of the technical department of the university of sao paulo-sibi/usp, brazil. electronic library for scientific journals i krzyzanowski andtaruhn 61 ! reproduced with permission of the copyright owner. further reproduction prohibited without permission. physical figure 1. infrastructure resources for consortium formation line also savs that one of the reasons for the growth in the number o'f electronic publications is "that it is technically possible to make them [journals] accessible in this way, and in fact easy and cheap, since nearly all te_xt ~oes through a digital version on the way to pubh~ahon. secondly, journal publishers believe that electronic ve~sions provide a second market in addition to that for t~eir printed versions, or at least in an expanded market, since many users will be the same." 4 . . . . . it is important to point out that the sc1enhhc penod1cal, be it paper or electronic, must ensure market valu_e and academic community receptivity, have a staff qualified for scientific publishing, be consistent in publishing release dates, comply with international standards, and use established distribution and sales mechanisms. 5 line goes further: "electronic publication as an_ 'extra' to printed publication has few added costs of j~urnal publication other than those of printing, and pubhshe~s are not going to want to make less money fro~ elect~onic journals than they do from printed ones. while p~inted journals once acquired can be used and reused without extra cost, each access to an electronic article has to be paid for. and although the costs of storage and binding may be saved, these are offset by the costs of printing out."6 he then notes that this technology demands an active equipment and telecommunication infrastructure. another point he addresses is the need for users to master the search strategies required to efficiently recover information, thus reducing the time spent and costs. in turn, saunders points out that, depending on the contracts made with the publishers or their agents: 62 information technology and libraries i june 2000 libraries, through their development, formation, and maintenance policies, should be receptive to this transition by accommodating the different means of communication to the different user needs and striving for a new balance. these policies should certainly stress the cooperation and sharing of remote access to the information demanded. budget estimates should, therefore, foresee, in addition to the subscriptions to electronic titles with complete texts, other possible items like licensing rates for multi-user remote access and the right to copy articles on electronic media to paper, depending on the contracts made with the publishers or their agents.7 i electronic publication consortiums catering to mutual interests by setting up a library consortium to select, acquire, maintain, and preserve electronic information is one means of reducing or sharing costs as well as expanding the universe of information available to users and ensuring a successful outcome. resources-physical, human, financial, and electronic-are combined for the common good; in this case, the consortium, as shown in figure 1, which was extracted and adapted from an oclc institute. 8 the consortium presupposes invigoration of cooperative activities among member libraries by promoting the central administration of electronic publication databases as part of a shared library system visible to all and replete with access facilities. in addition to putting in place simplified, reciprocal lending progra~s and spu_rring _the cooperative development of collections and the~r st~nng, the consortium has the objective of implementing information distribution by electronic means, provided that copyright and fair use rights are complied _wi~h.9 on t~e other hand, "the research library community is committed to working with publishers and database producers to develop model agreements that deploy lice~ses that d? not contract around fair use or other copynght provisions. in this way, one seeks to insure the library practices being disseminated, especially interli?~ary lendi~g."'. 0 experience shows that acqumng ~ubhcahons through consortia has brought great benefits and has equally favored different size institutions that would not be able to afford single subscriptions, whether on paper or in electronic format. north american and european universities have been opting for this type of alliance to augment inve~tment cost-benefit. important examples of these consortia currently operative are: • washington research library consortium, washington, d.c., www.wric.org; reproduced with permission of the copyright owner. further reproduction prohibited without permission. • university system of georgia, galileo project, www.galileo.peachnet.edu; • committee on institutional cooperation, michigan, www.cedar.cic.net/ cic; and • ohio library and information network, ohio link, www.ohiolink.edu. i the electronic consortium in the state of sao paulo considering that brazilian institutions also are being affected by the high cost of maintaining periodical collections and that alternative means of distributing this information are available, the model used abroad has shown itself as appropriate for developing the international scientific publications electronic library in the state of sao paulo. the location has a favorable information infrastructure available, particularly that of the electronic network of the academic network of sao paulo (ansp), thanks to the support of the research support foundation of the state of sao paulo (fapesp). 11 growing user demand for direct, convenient access to information in the state of sao paulo also was a factor in location choice. the final decision was to compose the consortium of five sao paulo state universitiesuniversidade de sao paulo (usp), universidade estadual paulista (unesp), universidade de campinas (unicamp), universidade federal de sao carlos (ufscar), and universidade federal de sao paulo (unifesp)-as well as the latin american and caribbean center for health science information (bireme). the consortium's goal was to make available to the member institutions' entire scientific community-10,492 faculty and researchers -rapid access to the complete, updated texts of the elsevier science scientific journals. this publishing house, an umbrella for north holland, pergamon press, butterworth-einemann, and excerpta medica, presently publishes electronic versions of its journals. selection of the member institutions that would serve as a pilot group for this project was based on prior experience with the cooperative work in preparing the unibibli collective catalog cd-rom, which, using bireme/opas/oms technology, consolidates the collections of these three universities. the project was initially funded by the fapesp; since its fourth edition the cdrom has been published through funds provided by the universities themselves, by means of a signed agreement. moreover, choice of elsevier science, which would be justified solely by its premier ranking in the global publishing market, also is due to the fact that consortium member institutions maintain subscriptions to a great number (606) of this publishing house's titles on paper. already fully available on electronic media, these titles are components of a representative collection initiating the building of the international scientific publications electronic library in the state of sao paulo. furthermore, the majority of the titles are studied on the institute of scientific information's web of science site, which has been at the disposal of researchers and libraries in the state of sao paulo since 1998. consortium objectives the consortium was formed to contribute to the development of research through the acquisition of electronic publications for the state of sao paulo's scientific community. using the ansp network, in addition to augmenting and speeding up access to current scientific information in all the member institutions, will: • increase the cost-benefit per subscription; • promote the rational use of funds; • ensure continuous subscription to these periodicals; • increase the universe of publications available to users through collection sharing; • guarantee local storage of the information acquired and thus ensure the collection's maintenance and its continual use by present and future researchers; and • develop the technical capabilities of the personnel of the state of sao paulo institutions in operating and using electronic publication databases. initially, the project will not interfere in the current process of acquiring periodicals on paper and in distributing collections in member institutions. however, as electronic collection utilization becomes predominant, duplicate subscriptions to paper may be eliminated so as to allow new subscriptions to be available to the consortium at no additional cost. implementation of the electronic library for international scientific publications implementation of this project includes the following stages already achieved: • constitution of the consortium by the six member institutions; and • set up of an administrative board. the following stages are in progress: • purchase of hardware (central server) and a software manager; and • estimate for the installation of the operational system. electronic library for scientific journals i krzyzanowski and taruhn 63 reproduced with permission of the

for storage and availability of electronic scientific periodical collections on the ansp network, be located at fapesp in order to facilitate development of an electronic bank. in the future, the bank should, in addition to the collection in mind for the project, include international collections of other publishing houses: the scielo collection of brazilian scientific magazines (project fapesp /bireme) as well as the web of science and current contents connect reference databases (see figure 2). consortium management the electronic library will be administrated by the consortium's administrative board, made up of a general coordinator, an operations coordinator, and directors and coordinators of the library systems and central libraries of member institutions as well as consultants recommended by fapesp. the administrative board shall be in charge of the implementation, operation, dissemination, and assessment of electronic library utilization. it also is charged 64 information technology and libraries i june 2000 with supervising qualified personnel training in order to guarantee the success of the project. an agreement specifying the consortium objective, its constitution, the manner by which it shall be executed and consortium member obligations established was signed. shortly, a contract to use elsevier science electronic publications shall be signed by fapesp and by the provider. the agreement's documents and use license were drawn up in compliance with the principles for licensing electronic resources recommended by the american library association, published in final version at the 1997 american library association annual conference.12 i recovery system and information use evaluation research on electronic media suggests that use of a single software program that offers different strategies and forms of interacting for searching the collections requires an evaluation of the efficiency of individual research strategies. this evaluation is critical for preparation of guidelines that orient the choice of systems and proper training programs.13 for the electronic library, the challenge of measuring not only the amount of file use but also the efficacy and efficiency of its information access systems and training for its users is an imperative task. in the project reproduced with permission of the copyright owner. further reproduction prohibited without permission. described, evaluation shall be made by indicators that demonstrate use of the electronic library and of the collections on paper, per journal title, subject researched, user institution, number of accesses per day, and user satisfaction regarding service provided (interface, response time, text copies), among other factors to be studied. i final remarks the way in which electronic media are read by the users is a code far beyond the written, because sound and image are being added increasingly. in this first generation of electronic publications, fapesp supported availability of web of science and of scielo by fapesp and the creation of the international scientific publications electronic library in the state of sao paulo. the possible introduction of current contents connect will trigger an extraordinary leap in research development, facilitating the access of scientific information and the acquisition and transmission of human knowledge as well as enhancing the cooperative and sharing enterprise of member libraries. references and notes l. annual report of the board of regents of tile smit/zsonum institution ...

and flora shrode mobile technologies & academics | dresselhaus and shrode 82 abstract in this paper we report on two surveys and offer an introductory plan that librarians may use to begin implementing mobile access to selected library databases and services. results from the first survey helped us to gain insight into where students at utah state university (usu) in logan, utah, stand regarding their use of mobile devices for academic activities in general and their desire for access to library services and resources in particular. a second survey, conducted with librarians, gave us an idea of the extent to which responding libraries offer mobile access, their future plans for mobile implementation, and their opinions about whether and how mobile technologies may be useful to library patrons. in the last segment of the paper, we outline steps librarians can take as they “go mobile.” purpose of the study similar to colleagues in all types of libraries around the world, librarians at utah state university (usu) want to take advantage of opportunities to provide information resources and library services via mobile devices. observing growing popularity of mobile, internetcapable telephones and computing devices, usu librarians assume that at least some users would welcome the ability to use such devices to connect to library resources. to find out what mobile services or vendors’ applications usu students would be likely to use, we conducted a needs assessment. the lessons learned will provide important guidance to management decisions about how librarians and staff members devote time and effort toward implementing and developing mobile access. we conducted a survey of usu’s students (approximately 25,000 undergraduates and graduates) to determine the degree of handheld device usage in the student population, the purposes for which students use such devices, and students’ interests in mobile access to the library. in addition, we surveyed librarians to learn about libraries’ current and future plans to launch mobile services. this survey was administered to an opportunistic population angela dresselhaus (aldresselhaus@gmail.com) was electronic resources librarian, flora shrode (flora.shrode@usu.edu) is head, reference & instruction services, utah state university, logan, utah. mailto:aldresselhaus@gmail.com mailto:flora.shrode@usu.edu information technology and libraries | june 2012 83 comprised of subscribers to seven e-mail lists whom we invited to offer feedback. our goal was to develop an action plan that would be responsive to students’ interests. at the same time, we aim to take advantage of the growing awareness of and demand for mobile access and to balance workloads among the library information technology professionals who would implement these services. usu is utah’s land-grant university and the merrill-cazier library is its primary library facility on the home campus in logan, utah. while usu has had satellite branches for some time, a growing emphasis on expanding online and distance education courses and degree programs has resulted in a considerable growth of its distance education programs in the last five years. mobile access to university resources makes especially good sense for the distance education population and for students who may reside close to the main usu campus but who also enroll in online courses. the library has an information technology staff of 4.5 fte professionals who support the library catalog, maintain roughly 250 computer workstations in cooperation with the director of campus student computer labs, and oversee the computing needs of library staff and faculty members. literature review mobile access to library resources is not a new concept; in fact, the first project designed to deliver handheld mobile access to library patrons began eighteen years ago, in 1993, the time of mainframe computers and gopher. the “library without a roof” project partners included the university of southern alabama, at&t, bellsouth cellular, and notable technologies, inc. 1 library patrons at participating institutions could search and read electronic texts on their personal digital assistants (pdas) and search the library catalog while browsing in physical collections. as reflected in the literature, interest in pda applications for libraries started to pick up around the turn of the twenty-first century. medical librarians were among the first to widely recognize the potential impact of mobile technologies on librarianship. a 2002 article in the journal of the medical library association and a monograph by colleen cuddy are among the first publications that focus on pdas. 2 a quick perusal of the medical category on the itunes store reveals several professional applications, ranging from new england journal of medicine tools to remote patient vital-sign monitors. as an example of the depth of mobile-device penetration in the medical field, in 2010 the food and drug administration approved the marketing of the airstrip suite of mobile-device applications. these apps work in conjunction with vital-sign monitoring equipment to allow instant remote access to a patient’s vital signs. 3 these examples illustrate the increasing pervasiveness of mobile technology in everyday life. mobile learning in academic areas outside of medicine has increased recently as more universities have adopted mobile technologies. 4 a sampling of current projects at academic mobile technologies & academics | dresselhaus and shrode 84 institutions is provided in the 2010 horizon report. 5 according to the 2010 educause center for applied research (ecar) study, 49 percent of undergraduates consider themselves mainstream adopters of technology. 6 locally, utah state university students have adopted smartphones at the rate of 39.3 percent and other handheld internet devices at the rate of 31.5 percent. these statistics indicate that skills are increasing and the technological landscape is changing quickly. the ecar study reports that student computing is rapidly moving to the cloud, another indication of the rapid change in the use of technology. “usb may one day go the way of the eight-track tape as laptops, netbooks, smartphones and other portable devices enable students to access their content from anywhere. they may or may not be aware of it, but many of today’s undergraduates are already cloud-savvy information consumers, and higher education is slowly but surely following their lead.” 7 similarly, usu students show interest in adopting new technology. while usu students are less likely to own mobile devices, 70.2 percent of respondents indicated that they would be likely or very likely to use library resources on smartphones if they owned capable devices and if the library provided easy access to materials. bridges, gascho rempel, and griggs published a comprehensive article, “making the case for a fully mobile library web site: from floor maps to the catalog,” detailing their efforts to implement mobile services on the oregon state university campus. 8 their paper highlights the popularity of mobile phones and smartphones/web-enabled phones. the authors discuss mobile phone use, library mobile websites, and mobile catalogs, and they describe the process they used to develop their mobile library site. they note that mobile services will certainly be expected in the coming years, and we have learned that usu students share this expectation. survey research in recent years librarians have conducted surveys on mobile technology in libraries. in a 2007 study, cummings, merrill, and borrelli surveyed library patrons to find out if they are likely to access the library catalog via small-screen devices. 9 they discovered that 45.2 percent of respondents, regardless of whether they owned a device, would access the library catalog on a small-screen device. mobile access to the library catalog was the most requested service in the usu student survey, although it accounted for only 16percent of the responses. cummings, et al. also discovered that the most frequent users of the catalog were also the least willing to access the catalog via mobile devices, an interesting observation that merits further research. their survey was completed in june of 2007, just five months after the january 9th release of the original iphone. the release of the iphone is significant as the point where the market demographics of mobile device users began to shift to people under thirty, the primary age group of undergraduate students. 10 librarians wilson and mccarthy at ryerson university conducted two surveys to measure information technology and libraries | june 2012 85 the usage of their catalog’s feature to send a call number via text or email (initiated in 2007) and their “fledgling mobile web site” (launched in 2008). 11 the first survey indicated that 20 percent of respondents owned internet-capable cell phones, and over half said they intended to buy this type of phone when their current contracts expired. the survey respondents indicated they wanted the following services: “booking group study rooms, checking hours and schedules, checking their borrower records and checking the catalogue.” 12 the second survey was conducted a year after the library had implemented a group study room reservation system, catalog and borrower record services, and a computer/laptop availability service. results of the follow-up survey show a drastic increase in ownership of internetcapable cell phones (from 20% to 65%). respondents desired two new services: article searches and e-book access. wilson and mccarthy found that very few library patrons were accessing the mobile services, but “60% of the survey respondents were unaware that the library provided mobile services.” 13 the authors conclude that advertising should be a central part of mobile technology implementation. they also detail how the library contributed expertise and leadership to their campus-wide mobile initiatives. seeholzer and salem conducted a series of focus groups in the spring of 2009 to determine the extent of mobile device use among students at kent state university. 14 notable among their findings are that students are willing to conduct research with mobile devices, and they desire to have a feature-rich interactive experience via handheld devices. students expressed interest in customizing interactions with the library’s mobile site and completing common tasks such as placing holds or renewing library materials. nationwide survey of librarians we asked colleagues who subscribe to e-mail distribution lists to respond to a survey about their libraries’ implementation of mobile applications for access to library collections and services. invitations to take the survey were sent to seven lists (acrl science & technology section, eril, information literacy instruction, liblicense-l, nasig, ref-l, and serialist), and 289 librarians and library staff members responded to the survey. the population of subscribers to the e-mail lists we used to solicit survey responses is dynamic and includes librarians and staff who work in academic and other types of settings. while our findings cannot be generalized in a statistically reliable manner, we nonetheless believe that the survey responses merit thorough analysis. we chose to conduct two surveys to avoid some of the problems we noted in a 2007 study conducted by todd spires. 15 spires’ survey questions focused on librarians’ perceptions rather than on empirical data. we developed separate surveys for librarians and students in hopes of avoiding problems that could arise from basing assumptions on perceived behavior or from the complexity of interpreting and generalizing from perceptions. a survey of library patrons should provide more accurate insight into the ways that patrons are using the library mobile technologies & academics | dresselhaus and shrode 86 via handheld devices. in the libraries that currently provide mobile access to resources, the library catalog is most commonly offered. article databases and assistance from a librarian tie as the second most frequently provided services. figure 1 shows a snapshot of the resources and services librarians reported that they provide. we also asked how long libraries have provided mobile access, and the time periods ranged from a few weeks to more than ten years. five librarians indicated that they have provided mobile access for six to ten years, and it is possible that these respondents may work in medical or health science libraries, as our literature review indicated that access to medical information and journal articles via pdas has been a reality for several years. figure 1. librarians’ responses: does your library provide mobile access to the following library resources? librarians were also asked what services and resources they believe libraries should provide via mobile devices. of one hundred seventy-eight responses, 71 percent indicated that “everything” or a variety of library resources should be made available. a few of the more interesting suggestions include a library café webcam (similar to a popular link from north carolina state university), locker reservations, a virtual suggestion box, alerts about database trials, an app that lists new books, and using ipads or other mobile devices for roving reference. roving reference with tablet pcs was evaluated by smith and pietraszewski at the west campus branch library of texas a&m. 16 as tablet computers become increasingly popular with the release of the ipad and other tablets, 17 roving reference should be reconsidered. smith and pietraszewski note that "the tablet pc proved to be an extremely useful device as well as a novelty that drew student interest (anything to make reference librarians look cool!)" 18 using the latest technology in libraries will help raise awareness that libraries are relevant and adapting to changing user preferences. we asked librarians to indicate who had responsibility for implementing mobile access in their library. the 184 responses are summarized here:  63 percent answered that a library systems or computing professional does this work;  26.1 percent indicated that the electronic resources librarian has this role;  17.9 percent rely on an information professional from outside of the library;  22.8 percent chose “other,” and we unfortunately did not offer a space for comments where survey respondents could tell us the job title of the person in their library who implements mobile access. the results from our sample of librarians are consistent with a larger study by the library journal. 19 the lj study found that the majority of academic libraries have implemented or are information technology and libraries | june 2012 87 planning to implement mobile technologies. student survey in january of 2011 we sent out a thirteen-question survey to students (questions are available in appendix a). usu’s student headcount is 25,767, and 3,074 students responded, representing 11.9 percent of the student population. we asked students to identify with colleges so that we could evaluate the survey sample against the enrollment at usu. the rate of response by college clustered between 12–19 percent with the lowest response rate (8 percent) from the college of education. the highest response rate came from the college of humanities and social sciences. we examined survey response rates from usu undergraduate and graduate populations; 54 percent of undergraduates and 50 percent of graduate students use mobile technology for academic purposes. we believe that our sample is sufficiently representative of the overall population of usu. figure 2. student response rates by college in order to understand the context of survey questions that specifically address mobile access, we asked students how often they used library electronic resources. the majority of students used electronic books, the library catalog, and electronic journals/articles a few times each semester. only 34.4 percent of students never use electronic books, 19.6 percent never use the library catalog, and 17.6 percent never use electronic journals/articles. we made comparisons between disciplines and found no significant difference in electronic resource use between fields in the sciences and those in humanities. further data will be collected in fall 2011 about use of print and electronic materials. mobile technologies & academics | dresselhaus and shrode 88 figure 3. electronic resource use among students students were asked how often they use a variety of handheld devices. we decided to emphasize access over ownership in order to allow for a variety of situations. responses show that 39.3 percent of our students use a smartphone with internet access on a daily basis. another 31.5 percent of students use other handheld devices like an ipod touch on a daily basis. very few students use ipads or e-book readers, with 3.9 percent and 5.4 percent indicating daily use, respectively. we view the "other handheld device" category as an important segment of the mobile technology market because of the lower cost barrier, since such devices do not require a subscription to a data plan. the ecar study also noted the possibility of cost factors influencing the decision of some students not to access the internet via a handheld device. 20 information technology and libraries | june 2012 89 figure 4. mobile device usage students were asked if they use their mobile device or phone for academic purposes (e.g., blackboard, electronic course reserves, etc.). this question was intentionally worded broadly in order to gather general information. we used skip logic to direct respondents to different paths through the survey based on their response to earlier questions. in response to a question about how students use their mobile devices, 54 percent of respondents indicated that they use their mobile devices for academic purposes. we analyzed the results by discipline and noted a few variances. among students responding from the school of business, 63 percent said that they use their mobile device for academic purposes, and 59 percent of engineering students use their devices for school work. the respondents from the other colleges reported use under 50 percent, most likely because of more limited adoption of mobile technology by usu faculty in those fields or lack of personal funds (or unwillingness to spend) to acquire devices and data plans. the 2010 ecar report also noted higher exposure to technology in these fields, indicating that the situation at usu is in line with results from a national study. 21 mobile technologies & academics | dresselhaus and shrode 90 table 1. device use for academic purposes by college we asked the students, “if library resources were easily accessible on your mobile devices, and if you had such a device, how likely would you be to use any of the following for assignments or research?” responses to this question allowed us to gauge interest without concerns about cost of technology or the current state of mobile readiness in our library. among the survey respondents, 70.2 percent are likely or very likely to use resources on a smartphone; 46.9 percent are likely or very likely to use resources on an ipad; 45.9 percent are likely or very likely to use resources on an e-book reader; 63.2 percent are likely or very likely to use resources on other devices. we included an option for respondents to select “not applicable” as distinct from “not likely” to allow for those students who may welcome use of a mobile device but who may currently use a device different from the types we specified. information technology and libraries | june 2012 91 figure 5. likelihood of using library resources on mobile device if easily available we are unsure how to account for the dramatic difference in interest between smartphone and ipad usage. survey responses indicated that only a small number of students have access to an ipad, and it is possible that students have had little opportunity to see their classmates or others use ipads in an academic setting. students were asked in a free-text question to list the services the library should offer. the comments were varied and often used language different from the vocabulary that librarians typically use. in order to gain an understanding of trends and to standardize the language, we coded the survey comments. after coding, trends began to emerge. access to the library catalog was mentioned by 16 percent of respondents. mobile services in general were specified by 11 percent of survey respondents, 10 percent wanted articles, and 9 percent wanted to reserve study rooms on their mobile device. the phrase “mobile services” represents a catch-all tag designated for comments that indicated that a student desired a variety of services or all services that are possible. for example, only 9 percent of respondents indicated they had used text to contact the library and 15percent had used instant messaging. several students indicated they might have used these services but did not know they were available, indicating a need for advertising. while we learned much mobile technologies & academics | dresselhaus and shrode 92 about students’ desires for mobile services from this important subset of comments in response to the free-text question, they did not prove especially useful to guide librarians’ plans for the next stages of implementing mobile technology. figure 6. services requested by students as is common at many institutions, funding at usu is limited and any development in the area of mobile access implementation must be strategic. our survey indicated that usu students are using mobile devices for their academic work and would like to further integrate library resources into their mobile routine. the next section of this paper outlines the steps we are taking toward mobile implementation. going mobile the usu library joins many other academic libraries in the beginning stages of implementing mobile technologies. survey responses from students indicate that they use mobile devices for academic purposes, and until options to use the library with such devices are available and advertised, we will not have a clear understanding of students’ preferences. klatt's article, “going mobile: free and easy,” 22 outlines a way to get started with mobile services with small investments of time and money. articles by griggs, 23 back, 24 and west, 25 and books by green, et al. 26 and hanson 27 also provide guidance in this area. here we offer suggestions to establish an implementation team, conduct an environmental scan, outline steps to begin the process, and shed light on advertising, assessment, and policy issues. information technology and libraries | june 2012 93 implementation team for a library seeking to provide mobile access to online resources, a diverse and talented implementation team is important. public services personnel in an academic library staff are on the front lines and often field students’ questions. they may also have the opportunity to observe how students are using mobile devices in the library. if librarians track reference interactions, they may find evidence that students are attempting to use their mobile devices to access library services. the electronic resources/collections specialist will also play a key role in mobile development. these specialists are often in contact with vendors, and their advocacy is important in encouraging mobile web development in the vendor community. a web site coordinator interested in mobile services and knowledgeable in current web standards will bring essential talent to the team. arguably, a mobile-optimized web site should become a standard level of service. web sites that are optimized or adapted specifically for mobile access are device agnostic and do not require advanced knowledge of smart phone operating systems. therefore existing web development staff can apply their current skill set to expand into mobile web design. in order to launch advanced interactive access to library resources, a programmer who is interested in developing mobile apps on a number of platforms is needed. device-specific applications allow for the use of phone features such as gps and orientation sensing via an accelerometer and provide the basis for augmented reality technologies. environmental scan librarians can learn about mobile usage in their community by gathering information to guide future development. at usu we interpret the numbers of students who use mobile devices for academic purposes as justification for implementing mobile library access, but we have not set a benchmark for a degree of interest that would trigger more development. some of the mobile implementations described at the end of this paper required minimal time or were investigated because of the electronic resources librarian’s interest for their relevance to her role as music subject librarian. in the survey we administered to students, we considered it important to include a wide range of devices, including ipod touches and similar devices that have many of the same possibilities for academic use as smartphones but which do not require a monthly contract. laptops are also considered a mobile technology, and while we did not emphasize this class of devices, some student comments referred specifically to laptop computers. we will monitor use of the mobile applications that we implement and likely conduct a follow-up survey to assess students’ satisfaction and to find out if there are other services they would like for the library to provide. while librarians may gather useful information from a user study, there are other ways to determine if students are, in fact, using mobile devices in the library. one approach is to review logs of reference questions to determine if students are inquiring about access to library resources via mobile devices. recently, a few mobile-related questions have surfaced mobile technologies & academics | dresselhaus and shrode 94 at usu in the libstats program used to track reference interactions. this is also an area where training reference staff to recognize and record questions about mobile access could be helpful to detect demand in the library’s community. if vendors provide statistics about use of their products from mobile devices, this information could also contribute to assessing need. finally, in libraries that use vpn or other off-campus authentication methods, consulting with it support staff to see if they field questions on setting up remote access on smartphones or other devices may factor into decisions regarding mobile access. the usu information technology website provides a knowledgebase that includes entries on a variety of mobile device queries. this indicates to librarians that people in the university community are using their mobile devices for academic functions. before we conducted the survey of usu students, we knew little about the exact nature of their mobile use. getting started after identifying the needs on campus, the next step is to create a plan for mobile implementation. an important aspect of anticipating the needs of a library’s user population is to understand the likely use scenarios, goals, tasks, and context as outlined in “library/mobile: tips on designing and developing mobile web sites.” 28 building on services that incorporate tasks that people already perform in non-academic contexts provides a logical bridge for those who are familiar with everyday use of a mobile device to recognize how such devices can serve academic purposes. gathering information from each vendor that supplies content to the library is an important early step in planning. this information can serve as the basis of a mobile web implementation plan and, in the case of ebsco, creating a profile is necessary in order to allow access to a mobile-formatted platform. at usu our online catalog provider has developed an application for apple's ios platform. if a library’s catalog vendor does not offer a dedicated application or mobile site, samuel liston’s comparisons of three major online catalogs on three popular mobile devices is helpful in gaining an understanding of how opacs display on smartphones. his article also outlines a procedure for testing opacs and usability. 29 at usu we can also take advantage of serials solutions’ mobile-optimized search screen and a variety of applications provided by other vendors. jensen noted that librarians should not rely solely on vendor-created applications due to vendors’ tendency to develop applications that are usable by only a segment of the overall mobile device user population. 30 he adds that libraries should also avoid developing applications for limited platforms. in addition, jensen provides a simple step-by-step process for converting articles retrieved from a vendor database to a format that can be downloaded from electronic course reserves and read on a variety of handheld devices. while using vendor-developed applications is an important strategy, most libraries will find that developing a mobile-compatible library website is necessary. information technology and libraries | june 2012 95 mobile website development can be accomplished in a variety of ways. at usu we plan to offer a version of our regular website by employing cascading style sheets (css). this method is described in the paper by bridges, et al., 31 and standard guidelines can be found in the mobile web best practices 1.0. 32 this method will allow the content to be reformatted at the point of need for a variety of platforms. results from the usu student survey indicate a desire to be able to use a mobile device for access to the library catalog, to use services like reference assistance, find articles, and make study room reservations. the library plans to include hours and location information, access to existing reference chat and text features, and links to databases with mobile friendly websites or vendor-created applications in addition to the resources requested by students. we are still unsure of the best way to provide links to applications and how to explain the various authentication methods required by each vendor. while vpn and ezproxy are possible methods to authenticate via mobile devices, vendors are content at the moment to allow students to access their resources by setting up an account that is based on an authorized e-mail domain or through a user account created on the non-mobile version of the resource. in a few cases at usu, mobile applications from vendors allow access to categories of users such as alumni because they have a usu.edu e-mail address, although the library does not typically include these patrons in our authorized remote user group. advertising, assessment, and policy creating a mobile website and offering mobile services are only the beginning of the effort to provide access to library materials for mobile users. as wilson and mccarthy found, advertising is essential; 33 students won’t use a service they don’t know about. crafting a marketing plan with both online and print materials is essential. educating library staff members, especially those on the public services front line, is an essential part of promoting mobile services. assessment strategies must be developed in order to focus development strategically. periodic surveys and focus groups can inform future development of mobile services and gauge the impact of currently offered services. librarians should encourage vendors to provide usage data for their mobile portals or applications, and libraries can track use data from their own information technology departments. implementation of mobile web services creates the need to develop new policies and to educate staff. privacy concerns and the complexities of digital rights management have the potential to transform the role of the library and its policies. 34 patrons will need to be aware that the library has less control over maintaining privacy when materials are accessed via third-party mobile applications. libraries will need to consider how new developments in pricing models may affect expanding mobile access; one example is harpercollins’ announcement in early 2011 about a policy requiring libraries to repurchase individual e mobile technologies & academics | dresselhaus and shrode 96 book titles after a cap on check-outs is reached. 35 librarians’ desire to offer reference services or other assistance via mobile devices follows naturally from their long-standing efforts to enable patrons to ask questions via e-mail, chat, instant messaging, or sms text. instant messaging, chat, and text lend themselves to mobile access because they are designed for the relatively short exchange that people typically use when communicating with a handheld device. offering reference services using sms text and chat in particular are relatively easy for libraries to employ because there are many free services to support them. in some cases, a systems administrator or it expert may be helpful in navigating the set-up of chat and text services and to integrate them so that, for example, when a text message arrives during a time when no one is monitoring the service, a voicemail message automatically appears in library’s e-mail account. librarians can find an enormous amount of advice on the web and in the literature about how to begin offering mobilefriendly reference, how to expand the virtual reference services they currently provide, and how to choose among free and fee-based services for their library’s needs and budget. two efficient places to begin are cody hanson’s special issue of library technology reports, which provides a thorough overview of mobile devices and their capabilities and straightforward suggestions for planning and implementation, and m-libraries, a section of library success: a best practices wiki. 36 conclusion in light of trends toward more widespread use of mobile computing devices and smartphones, it makes sense for libraries to provide access to their collections and services in ways that work well with mobile devices. this case study presents the situation at the merrill-cazier library at utah state university, where students who responded to a survey indicate they are very interested in mobile access, even if they have not yet purchased a smartphone or find data plans to be too expensive at this point. as is only reasonable for any library, at usu we have begun by implementing mobile applications that are available from vendors of our online catalog and databases because these require minimal effort and no additional cost. we present ideas for establishing an implementation team and advice for academic libraries who wish to “go mobile.” we aim to have a concrete plan for the work that will be required to optimize the library’s website for mobile access by the fall of 2011. a significant step is hiring a digital services librarian to work closely with the webmaster, electronic resources librarian, and others interested in promoting access to resources and services via mobile devices. our vision is to be on track to offer an augmented-reality experience to our patrons as the 2010 horizon report indicates will be an important trend in the next two to three years. we aim to create an environment in which students can use their mobile device to gain entry to a new layer of digital information, enhancing their experience in the physical library.

    microinteractions  and  the  user  experience     sonya  betz    and     robyn  hall     information  technology  and  libraries  |  september  2015             43   abstract   details  matter,  especially  when  they  can  influence  whether  users  engage  with  a  new  digital  initiative   that  relies  heavily  on  their  support.  during  the  recent  development  of  macewan  university’s   institutional  repository,  the  librarians  leading  the  project  wanted  to  ensure  the  site  would  offer  users   an  easy  and  effective  way  to  deposit  their  works,  in  turn  helping  to  ensure  the  repository’s  long-­‐term   viability.  the  following  paper  discusses  their  approach  to  user-­‐testing,  applying  dan  saffer’s   framework  of  microinteractions  to  how  faculty  members  experienced  the  repository’s  self-­‐archiving   functionality.  it  outlines  the  steps  taken  to  test  and  refine  the  self-­‐archiving  process,  shedding  light  on   how  others  may  apply  the  concept  of  microinteractions  to  better  understand  a  website’s  utility  and   the  overall  user  experience  that  it  delivers.     introduction   one  of  the  greatest  challenges  in  implementing  an  institutional  repository  (ir)  at  a  university  is   acquiring  faculty  buy-­‐in.  support  from  faculty  members  is  essential  to  ensuring  that  repositories   can  make  online  sharing  of  scholarly  materials  possible,  along  with  the  long-­‐term  digital   preservation  of  these  works.  many  open  access  mandates  have  begun  to  emerge  around  the  world,   developed  by  universities,  governments,  and  research  funding  organizations,  which  serve  to   increase  participation  through  requiring  that  faculty  contribute  their  works  to  a  repository.1   however,  for  many  staff  managing  irs  at  academic  libraries  there  are  no  enforceable  mandates  in   place,  and  only  a  fraction  of  faculty  works  can  be  contributed  without  copyright  implications  when   author  agreements  transfer  copyrights  to  publishers.  persuading  faculty  members  to  take  the  time   to  sort  through  their  works  and  self-­‐archive  those  that  are  not  bound  by  rights  restrictions  is  a   challenge.   standard  installations  of  popular  ir  software,  including  dspace,  digital  commons,  and  eprints,  do   little  to  help  facilitate  easy  and  efficient  ir  deposits  by  faculty.  as  dorothea  salo  writes  in  a  widely   cited  critique  of  irs  managed  by  academic  libraries,  the  “‘build  it  and  they  will  come’  proposition   has  been  decisively  wrong.”2  a  major  issue  she  points  out  is  that  repositories  were  predicated  on   the  “assumption  that  faculty  would  deposit,  describe,  and  manage  their  own  material.”3  seven     sonya  betz  (sonya.betz@ualberta.ca)  is  digital  initiatives  project  librarian,  university  of  alberta   libraries,  university  of  alberta,  edmonton,  alberta.  robyn  hall  (hallr27@macewan.ca)  is   scholarly  communications  librarian,  macewan  university  library,  macewan  university,   edmonton,  alberta.     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   44   years  after  the  publication  of  her  article,  a  vast  majority  of  the  more  than  2,600  repositories   currently  operating  around  the  world  still  function  in  this  way  and  struggle  to  attract  widespread   faculty  support.4  to  deposit  works  into  these  systems,  faculty  are  often  required  to  fill  out  an   online  form  to  describe  and  upload  each  work  individually.  this  can  be  a  laborious  process  that   includes  deciphering  lengthy  copyright  agreements,  filling  out  an  array  of  metadata  fields,  and   ensuring  file  formats  or  file  sizes  that  are  compatible  with  the  constraints  of  the  software.   in  august  of  2014,  macewan  university  library  in  edmonton,  alberta,  launched  an  ir,  research   online  at  macewan  (ro@m;  http://roam.macewan.ca).  our  hope  was  that  ro@m’s  simple  user   interface  and  straightforward  submission  process  would  help  to  bolster  faculty  contributions.  the   site  was  built  using  islandora,  an  open-­‐source  software  framework  that  offered  the  project   developers  substantial  flexibility  in  appearance  and  functionality.  in  an  effort  to  balance  their   desire  for  independence  over  their  work  with  ease  of  use,  faculty  and  staff  have  the  option  of   submitting  to  ro@m  in  one  of  two  ways:  they  can  choose  to  complete  a  brief  process  to  create   basic  metadata  and  upload  their  work,  or  they  can  simply  upload  their  work  and  have  ro@m  staff   create  metadata  and  complete  the  deposit.     thoroughly  testing  both  of  these  processes  was  critical  to  the  success  of  the  ir.  we  wanted  to   ensure  that  there  were  no  obstacles  in  the  design  that  would  dissuade  faculty  members  from   contributing  their  works  once  they  had  made  the  decision  to  start  the  contribution  process.  as  the   primary  means  of  adding  content  to  the  ir,  and  as  a  process  that  other  institutions  have  found   problematic,  carefully  designing  each  step  of  how  a  faculty  contributor  submits  material  was  our   highest  priority.  to  help  us  focus  our  testing  on  some  of  these  important  details,  and  to  provide  a   framework  of  understanding  for  refining  our  design,  we  turned  to  dan  saffer’s  2013  book   microinteractions:  designing  with  details.  the  following  case  study  describes  our  use  of   microinteractions  as  a  user-­‐testing  approach  for  libraries  and  discusses  what  we  learned  as  a   result.  we  seek  to  shed  light  on  how  other  repository  managers  might  envision  and  structure  their   own  self-­‐archiving  processes  to  ensure  buy-­‐in  while  still  relying  on  faculty  members  to  do  some  of   the  necessary  legwork.  additionally,  we  lay  out  how  other  digital  initiatives  may  embrace  the   concept  of  microinteractions  as  a  means  of  better  understanding  the  relationship  between  the   utility  of  a  website  and  the  true  value  of  positive  user  experience.     literature  review   user  experience  and  self-­‐archiving  in  institutional  repositories   user  experience  (ux)  in  libraries  has  gained  significant  traction  in  recent  years  and  provides  a   useful  framework  for  exploring  how  our  users  are  interacting  with,  and  finding  meaning  in,  the   library  technologies  we  create  and  support.  although  there  is  still  some  disagreement  around  the   definition  and  scope  of  what  exactly  we  mean  when  we  talk  about  ux,  there  seems  to  be  general   consensus  that  paying  attention  to  ux  shifts  focus  from  the  usability  of  a  product  to  more   nonutilitarian  qualities,  such  as  meaning,  affect,  and  value.5  hassenzhal  simply  defines  ux  as  a     information  technologies  and  libraries  |  september  2015   45   “momentary,  primarily  evaluative  feeling  (good-­‐bad)  while  interacting  with  a  product  or  service.”6   hassenzhal,  diefenbach,  and  goritz  argue  that  positive  emotional  experiences  with  technology   occur  when  the  interaction  fulfills  certain  psychological  needs,  such  as  competence  or  popularity.7   the  2010  iso  standard  for  human-­‐centered  design  for  interactive  systems  defines  ux  even  more   broadly,  suggesting  that  it  “includes  all  the  users’  emotions,  beliefs,  preferences,  perceptions,   physical  and  psychological  responses,  behaviors  and  accomplishments  that  occur  before,  during   and  after  use.”8  however,  when  creating  tools  for  library  environments,  it  can  be  difficult  for   practitioners  to  translate  ambiguous  emotional  requirements,  such  as  satisfying  emotional  and   psychological  needs  or  increasing  motivation,  with  pragmatic  outcomes,  such  as  developing  a   piece  of  functionality  or  designing  a  user  interface.   it  has  been  well  documented  that  repository  managers  struggle  to  motivate  academics  to  self-­‐ archive  their  works.9  however,  the  literature  focusing  on  how  ir  websites’  self-­‐archiving   functionality  helps  or  hinders  faculty  support  and  engagement  is  sparse.  one  study  of  note  was   conducted  by  kim  and  kim  in  2006,  who  led  usability  testing  and  focus  groups  on  an  ir  in  south   korea.  10  they  provide  a  number  of  ways  to  improve  usability  on  the  basis  of  their  findings,  which   include  avoiding  jargon  terms  and  providing  comprehensive  instructions  at  points  of  need  rather   than  burying  them  in  submenus.  similarly,  veiga  e  silva,  goncalves,  and  laender  reported  results   of  usability  testing  conducted  on  the  brazilian  digital  library  of  computing,  which  confirmed  their   initial  goals  of  building  a  self-­‐archiving  service  that  was  easily  learned,  comfortable,  and   efficient.11  the  authors  of  both  of  these  studies  suggest  that  user-­‐friendly  design  could  help  to   ensure  the  active  support  and  sustainability  of  their  services,  but  long-­‐term  use  remained  to  be   seen  at  the  time  of  publication.  meanwhile,  bell  and  sarr  recommend  integrating  value-­‐added   features  into  ir  websites  as  a  way  to  attract  faculty.12  their  successful  strategy  for  reengineering  a   struggling  ir  at  the  university  of  rochester  included  adding  tools  to  allow  users  to  edit  metadata   and  add  and  remove  files,  and  providing  portfolio  pages  where  faculty  could  list  their  works  in  the   ir,  link  to  works  available  elsewhere,  detail  their  research  interests,  and  upload  a  copy  of  their  cv.   although  the  question  remains  as  to  whether  a  positive  user  experience  in  an  ir  can  be  a   significant  motivating  factor  for  increasing  faculty  participation,  there  seems  to  be  enough   evidence  to  support  its  viability  as  an  approach.   applying  microinteractions  to  user  testing   dan  saffer’s  2013  book,  microinteractions:  designing  with  details,  follows  logically  from  the  ux   movement.  although  he  uses  the  phrase  “user  experience”  sparingly,  saffer  consistently  connects   interactive  technologies  with  the  emotional  and  psychological  mindset  of  the  user.  saffer  focuses   on  “microinteractions,”  which  he  defines  as  “a  contained  product  moment  that  revolves  around  a   single  use  case.”13  saffer  argues  that  well-­‐designed  microinteractions  are  “the  difference  between   a  product  you  love  and  product  you  tolerate.”14  saffer’s  framework  is  an  effective  application  of  ux   theory  to  a  pragmatic  task.  not  only  does  he  privilege  the  emotional  state  of  the  user  as  a  priority     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   46   for  design,  he  also  provides  concrete  recommendations  for  designing  technology  that  provokes   positive  psychological  states  such  as  pleasure,  engagement,  and  fun.   defining  what  we  mean  by  a  “microinteraction”  is  important  when  translating  saffer’s  theory  to  a   library  environment.  he  describes  a  microinteraction  as  “a  tiny  piece  of  functionality  that  only   does  one  thing  .  .  .  every  time  you  change  a  setting,  sync  your  data  or  devices,  set  an  alarm,  pick  a   password,  turn  on  an  appliance,  log  in,  set  a  status  message,  or  favorite  or  like  something,  you  are   engaging  with  a  microinteraction.”15  in  libraries,  many  microinteractions  are  built  around   common  user  tasks  such  as  booking  a  group-­‐use  room,  placing  a  hold  on  an  item,  registering  for  an   event,  rating  a  book,  or  conducting  a  search  in  a  discovery  tool.  a  single  piece  of  interactive  library   technology  may  have  any  number  of  discrete  microinteractions,  and  often  are  part  of  a  larger   ecosystem  of  connected  processes.  for  example,  an  integrated  library  system  is  composed  of   hundreds  of  microinteractions  designed  both  for  end  users  and  library  staff,  while  a  self-­‐checkout   machine  is  primarily  designed  to  facilitate  a  single  microinteraction.   saffer’s  framework  provided  a  valuable  new  lens  on  how  we  could  interpret  users’  interactions   with  our  ir.  while  we  generally  conceptualize  an  ir  as  a  searchable  collection  of  institutional   content,  we  can  also  understand  it  as  a  collection  of  microinteractions.  for  example,  ro@m’s  core   is  microinteractions  that  enable  tasks  such  as  searching  content,  browsing  content,  viewing  and   downloading  content,  logging  in,  submitting  content,  and  contacting  staff.  ro@m  also  includes   microinteractions  for  staff  to  upload,  review,  and  edit  content.  as  discussed  above,  one  of  the   primary  goals  when  developing  our  ir  was  to  allow  faculty  to  deposit  scholarly  content,  such  as   articles  and  conference  papers,  directly  to  the  repository.  we  wanted  this  process  to  be  simple  and   intuitive,  and  for  faculty  to  have  some  control  over  the  assignation  of  keywords  and  other   metadata,  but  also  to  have  the  option  to  simply  submit  content  with  minimal  effort.  we  decided  to   employ  user  testing  to  carefully  examine  the  deposit  process  as  a  discrete  microinteraction  and  to   apply  saffer’s  framework  as  a  means  of  assessing  both  functionality  and  ux.  we  hoped  that   focusing  on  the  details  of  that  particular  microinteraction  would  allow  us  to  make  careful  and   thoughtful  design  choices  that  would  lead  to  a  more  consistent  and  pleasurable  ux.   method  and  case  study   we  conducted  two  rounds  of  user  testing  for  the  self-­‐archiving  process.  our  initial  user  testing   was  conducted  in  january  2014.  we  asked  seven  faculty  to  review  and  comment  on  a  mockup  of   the  deposit  form  to  test  the  workflow.  this  simple  exercise  allowed  us  to  confirm  the  steps  in  the   upload  process,  and  identified  a  few  critical  issues  that  we  could  resolve  before  building  out  the  ir   in  islandora.  after  completing  the  development  of  the  ir,  and  with  a  working  copy  of  the  site   installed  on  our  user  acceptance  testing  (uat)  server,  we  conducted  a  second  round  of  in-­‐depth   usability  testing  within  our  new  microinteraction  framework.     in  april  2014  we  recruited  six  faculty  members  through  word  of  mouth  and  through  a  call  for   participants  in  the  university’s  weekly  electronic  staff  newsletter.  the  volunteers  represented   major  disciplines  at  macewan  university,  including  health  sciences,  social  sciences,  humanities,     information  technologies  and  libraries  |  september  2015   47   and  natural  sciences.  saffer  describes  a  process  for  testing  microinteractions  and  suggests  that  the   most  relevant  way  to  test  microinteractions  is  to  include  “hundreds  (if  not  thousands)  of   participants.”16  however,  he  goes  on  to  describe  the  most  effective  methods  of  testing  to  be   qualitative,  including  conversation,  interviews,  and  observation.  testing  thousands  of  participants   with  one-­‐on-­‐one  interviews  and  observation  sessions  is  well  beyond  the  means  of  most  academic   libraries,  and  runs  counter  to  standard  usability  testing  methodology.  while  testing  only  six   participants  may  seem  like  a  small  number,  and  one  that  is  apt  to  render  inconclusive  results  and   sparse  feedback,  it  is  strongly  supported  by  usability  experts,  such  as  jakob  nielson.  during  the   course  of  our  testing,  we  quickly  reached  what  nielson  refers  to  in  his  piece  “how  many  test  users   in  a  usability  study?”  as  “the  point  of  diminishing  returns.”17  he  suggests  that  for  most  qualitative   studies  aimed  at  gathering  insights  to  inform  site  design  and  overall  ux,  five  users  is  in  fact  a   suitable  number  of  participants.  we  support  his  recommendation  on  the  basis  of  our  own   experiences;  by  the  fourth  participant,  we  were  receiving  very  repetitive  feedback  on  what   worked  well  and  what  needed  to  be  changed.   testing  took  place  in  faculty  members’  offices  on  their  own  personal  computers  so  that  they  would   have  the  opportunity  to  engage  with  the  site  as  they  would  under  normal  workday  circumstances.   each  user  testing  session  lasted  45  to  60  minutes,  and  was  facilitated  by  three  members  of  the   ro@m  team:  the  web  and  ux  librarian  guided  each  faculty  member  through  the  testing  process,   the  scholarly  communications  librarian  observed  the  interaction,  and  a  library  technician  took   detailed  notes  recording  participant  comments  and  actions.  each  faculty  member  was  given  an   article  and  asked  to  contribute  that  article  to  ro@m  using  the  uat  site.  the  ro@m  team  observed   the  entire  process  carefully,  especially  noting  any  problematic  interactions,  while  encouraging  the   faculty  member  to  think  aloud.  once  testing  was  complete,  the  scholarly  communications  librarian   analyzed  the  notes  and  identified  areas  of  common  concern  and  confusion  among  participants,  as   well  as  several  suggestions  that  the  participants  made  to  improve  the  site’s  functionality  as  they   worked  through  the  process.  she  then  went  about  making  changes  to  the  site  based  on  this   feedback.  as  we  discuss  in  the  next  section,  each  task  that  faculty  members  performed,  from  easy   to  frustrating,  represented  an  interaction  with  the  user  interface  that  affected  participants’   experiences  of  engaging  with  the  contribution  process,  and  informed  changes  we  were  able  to   make  before  launching  the  ir  service  three  months  later.     basic  elements  of  microinteractions   saffer’s  theory  describes  four  primary  components  of  a  microinteraction:  the  trigger,  rules,   feedback,  and  loops  and  modes.  viewing  the  ir  upload  tool  as  a  microinteraction  intended  to  be   efficient  and  user-­‐friendly  required  us  to  first  identify  each  of  these  different  components  as  they   applied  to  the  contribution  process  (see  figure  1),  and  then  evaluate  the  tool  as  a  whole  through   our  user  testing.     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   48     figure  1.  ir  self-­‐archiving  process  with  microinteraction  components.   trigger   the  first  component  to  examine  in  a  microinteraction  is  the  trigger,  which  is,  quite  simply,   “whatever  initiates  the  microinteraction.”18  on  an  iphone,  a  trigger  for  an  application  might  be  the   icon  that  launches  an  app;  on  a  dishwasher,  the  trigger  would  be  the  button  pressed  to  start  the   machine;  on  a  website,  a  trigger  could  be  a  login  button  or  a  menu  item.  well-­‐designed  triggers   follow  good  usability  principles:  they  appear  when  and  where  the  user  needs  them,  they  initiate   the  same  action  every  time,  and  they  act  predictably  (for  example,  buttons  are  pushable,  toggles   slide).     information  technologies  and  libraries  |  september  2015   49   examining  our  trigger  was  a  first  step  in  assessing  how  well  our  upload  microinteraction  was   designed.  uploading  and  adding  content  is  a  primary  function  of  the  ir,  and  the  trigger  needed  to   be  highly  noticeable.  we  can  assume  that  users  would  be  goal-­‐based  in  their  approach  to  the  ir;   faculty  would  be  visiting  the  site  with  the  specific  purpose  of  uploading  content  and  would  be   actively  looking  for  a  trigger  to  begin  an  interaction  that  would  allow  them  to  do  so.     the  initial  design  of  ro@m  included  a  top-­‐level  menu  item  as  the  only  trigger  for  contributing   works.  in  the  persistent  navigation  at  the  top  of  the  site,  users  could  click  on  the  menu  item   labeled  “contribute”  where  they  would  then  be  presented  with  a  login  screen  to  begin  the   contribution  process.  this  was  immediately  obvious  to  half  of  the  participants  during  user  testing.   however,  the  other  half  immediately  clicked  on  the  word  “share,”  which  appeared  on  the  lower   half  of  the  page  beside  a  small  icon  simply  as  a  way  to  add  some  aesthetic  appeal  to  the  homepage   along  with  the  words  “discover”  and  “preserve.”  not  surprisingly,  the  users  were  interpreting  the   word  and  icon  as  a  trigger.  because  of  the  user  behavior  that  we  observed,  we  decided  to  add   hyperlinks  to  all  three  of  these  words,  with  “share”  linking  to  the  contribution  login  screen  (see   figure  2),  “discover”  leading  to  a  browse  page,  and  “preserve”  linking  to  an  faq  for  authors  page   that  included  information  on  digital  preservation.  this  increased  visibility  of  the  trigger   significantly  for  the  microinteraction.     figure  2.  “share”  as  additional  trigger  for  contributing  works.     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   50   rules   the  second  component  of  microinteractions  described  by  saffer  are  the  rules.  rules  are  the   parameters  that  govern  a  microinteraction;  they  provide  a  framework  of  understanding  to  help   users  succeed  at  completing  the  goal  of  a  microinteraction  by  defining  “what  can  and  cannot  be   done,  and  in  what  order.”19  while  users  don’t  need  to  understand  the  engineering  behind  a  library   self-­‐checkout  machine,  for  example,  they  do  need  to  understand  what  they  can  and  cannot  do   when  they’re  using  the  machine.  the  hardware  and  software  of  a  self-­‐checkout  machine  is   designed  to  support  the  rules  by  encouraging  users  to  scan  their  cards  to  start  the  machine,  to   align  their  books  or  videos  so  that  they  can  be  scanned  and  desensitized,  and  to  indicate  when   they  have  completed  the  interaction.   the  goal  when  designing  a  self-­‐archiving  process  in  ro@m  was  to  ensure  that  the  rules  were  easy   for  users  to  understand,  followed  a  logical  structure,  and  were  not  overly  complex.  to  this  end,  we   drew  on  saffer’s  approach  to  designing  rules  for  microinteractions,  along  with  the  philosophy   espoused  by  steve  krug  in  his  influential  web  design  book,  don’t  make  me  think:  a  common  sense   approach  to  web  usability.20  both  krug  and  saffer  argue  for  reducing  complexity  and  removing   decision-­‐making  from  the  user  whenever  possible  to  remove  potential  for  user  error  or  mistakes.   the  rules  in  ro@m  follow  a  familiar  form-­‐based  approach:  users  log  in  to  the  system,  they  have  to   agree  to  a  licensing  agreement,  they  create  some  metadata  for  their  item,  and  they  upload  a  file   (see  figure  1).  however,  determining  the  order  for  each  of  these  elements,  and  ensuring  that  users   could  understand  how  to  fill  out  the  form  successfully,  required  careful  thinking  that  was  greatly   informed  by  the  user  testing  we  conducted.   for  example,  we  designed  ro@m  to  connect  to  the  same  authentication  system  used  for  other   university  applications,  ensuring  that  faculty  could  log  in  with  the  credentials  they  use  daily  for   institutional  email  and  network  access.  forcing  faculty  to  create,  and  remember,  a  unique   username  and  password  to  submit  content  would  have  increased  the  possibility  of  login  errors   and  resulted  in  confusion  and  frustration.  we  also  used  drop-­‐down  options  where  possible   throughout  the  microinteraction  instead  of  requiring  faculty  to  input  data  such  as  file  types,   faculty  or  department  names,  or  content  types  into  free-­‐text  boxes.   during  our  user  testing  we  found  that  those  fields  where  we  had  free-­‐text  input  for  metadata   entry  most  often  led  to  confusion  and  errors.  for  instance,  it  quickly  became  apparent  that  name   authority  would  be  an  issue.  when  filling  out  the  “author”  field,  some  people  used  initials,  some   used  middle  names,  and  some  added  “dr”  before  their  name,  which  could  negatively  affect  the  ir’s   search  results  and  the  ability  to  track  where  and  when  these  works  may  be  cited  by  others.  when   asked  to  include  a  citation  for  published  works,  most  of  our  participants  noted  frustration  with   this  requirement  because  they  could  not  do  so  quickly,  and  they  had  concerns  about  creating   correct  citations.  finally,  many  participants  also  became  confused  at  the  last,  optional  field  in  the   form  that  allowed  them  to  assign  a  creative  commons  license  to  their  works.     information  technologies  and  libraries  |  september  2015   51   our  user  testing  indicated  that  we  would  need  to  be  mindful  of  how  information  like  author  names   and  citations  were  entered  by  users  before  making  an  item  available  on  the  site.  under  ideal   circumstances,  we  would  have  modified  the  form  to  ensure  that  any  information  that  the  system   knew  about  the  user  was  brought  forward:  what  saffer  calls  “don’t  start  from  zero.”21  this  could   include  automatically  filling  in  details  like  a  user’s  name.  however,  like  many  libraries,  we  chose  to   adapt  existing  software  rather  than  develop  our  microinteraction  from  the  ground  up;   implementing  such  changes  would  have  been  too  time-­‐consuming  or  expensive.  in  response,  we   instead  added  additional  workflows  to  allow  administrators  to  edit  the  metadata  before  a   contribution  would  be  published  to  the  web  so  we  could  correct  any  errors.  we  also  changed  the   “citation”  field  to  “publication  information”  to  imply  that  users  did  not  need  to  include  a  complete   citation.  lastly,  we  made  sure  that  “all  rights  reserved”  was  the  default  selection  for  the  optional   “add  a  creative  commons  license?”  field  in  the  form  because  this  was  language  that  with  which   our  users  were  familiar  with  and  comfortable  proceeding.     policy  constraints  are  another  aspect  of  the  rules  that  provide  structure  around  microinteractions,   and  can  also  limit  design  choices  that  can  be  made.  having  faculty  complete  a  nonexclusive   licensing  agreement  that  acknowledged  they  had  the  appropriate  copyright  permissions  to  allow   them  to  contribute  the  work  was  a  required  component  in  our  rules.  without  the  agreement,  we   would  risk  liability  for  copyright  infringement  and  could  not  accept  the  content  into  the  ir.   however,  our  early  designs  for  the  repository  included  this  step  at  the  end  of  the  submission   process,  after  faculty  had  created  metadata  about  the  item.  our  initial  round  of  testing  revealed   that  several  of  our  participants  were  unsure  of  whether  they  had  the  appropriate  copyright   permissions  to  add  content  and  didn’t  want  to  complete  the  submission,  a  frustrating  experience   for  them  after  spending  time  filling  out  author  information,  keywords,  abstract,  and  the  like.  we   attempted  to  resolve  this  issue  by  moving  the  agreement  much  earlier  in  the  process,  forcing  users   to  acknowledge  the  agreement  before  creating  any  metadata.  we  also  used  simple,   straightforward  language  for  the  agreement  and  added  additional  information  about  how  to   determine  copyrights  or  contact  ro@m  staff  for  assistance.  integrating  an  api  that  could   automatically  search  a  journal’s  archiving  policies  in  sherpa  romeo  at  this  stage  in  the   contribution  process  is  something  we  plan  to  investigate  to  help  reduce  complexity  further  for   users.     feedback   understanding  the  concept  of  feedback  is  critical  to  the  design  of  microinteractions.  while  most   libraries  are  familiar  with  collecting  feedback  from  users,  the  feedback  saffer  describes  is  flowing   in  the  opposite  direction,  and  instead  refers  to  feedback  the  application  or  interface  is  providing   back  to  users.  this  feedback  gives  users  information  when  and  where  they  need  it  to  help  them   navigate  the  microinteraction.  as  saffer  comments,  “the  true  purpose  of  feedback  is  to  help  users   understand  how  the  rules  of  the  microinteraction  work.”22     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   52   feedback  can  be  provided  in  a  variety  of  ways.  an  action  as  simple  as  a  color  change  when  a  user   hovers  over  a  link  is  a  form  of  feedback,  providing  visual  information  that  indicates  that  a  segment   of  text  can  be  clicked  on.  confirmation  messages  are  an  obvious  form  of  feedback,  while  a  folder   with  numbers  indicating  how  many  items  have  been  added  to  it  is  more  subtle.  while  visual   feedback  is  most  commonly  used,  saffer  also  describes  cases  where  auditory  and  haptic  (touch)   feedback  may  be  useful  .  designing  feedback,  much  like  designing  rules,  should  aim  to  reduce   complexity  and  confusion  for  a  user,  and  should  be  explicitly  connected  both  functionally  and   visually  to  what  the  user  needs  to  know.   in  an  online  web  environment,  much  of  the  feedback  we  provide  the  user  should  be  based  on  good   usability  principles.  for  example,  formatting  web  links  consistently  and  providing  predictable   navigation  elements  are  some  ways  that  feedback  can  be  built  into  a  design.  providing  feedback  at   the  users’  point  of  need  is  also  critical,  especially  error  messages  or  instructional  content.  this   proved  to  be  especially  important  to  our  ro@m  test  subjects.  while  the  ir  featured  an  “about”   section  accessible  in  the  persistent  navigation  at  the  top  of  the  website  that  contained  detailed   instructions  and  information  about  how  to  submit  works,  and  terms  of  use  governing  these   submissions,  this  content  was  virtually  invisible  to  the  users  we  observed.  instead,  they  relied   heavily  on  the  contextual  feedback  that  was  included  throughout  the  contribution  process  when  it   was  visible  to  them.     these  observations  led  us  to  rethink  our  approach  to  providing  feedback  in  several  cases.  for   example,  an  unfortunate  constraint  of  our  software  required  users  to  select  a  faculty  or  school  and   a  department  and  then  click  an  “add”  button  before  they  could  save  and  continue.  we  included   some  instructions  above  the  drop-­‐down  menus,  stating  “select  and  click  add”  in  an  effort  to   prevent  any  errors.  however,  our  participants  failed  to  notice  the  instructions  and  inevitably   triggered  a  brief  error  message  (see  figure  3).  we  later  changed  the  word  “add”  in  the  instructions   from  black  to  bright  red  hoping  to  increase  its  visibility,  and  we  ensured  that  the  error  message   that  displayed  when  users  failed  to  select  “add”  clearly  explained  how  to  correct  the  problem  and   move  on.  we  also  observed  that  the  plus  signs  to  add  additional  authors  and  keywords  were  not   visible  to  users.  we  added  feedback  that  included  both  text  and  icons  with  more  detail  (see  figure   4).  however,  this  remains  a  problem  for  users  that  we  will  need  to  further  explore.  on  completing   a  contribution,  users  receive  a  confirmation  page  that  thanks  them  for  the  contribution,  provides  a   timeline  for  when  the  item  will  appear  on  the  site,  and  notes  that  they  will  receive  an  email  when   it  appears.  response  to  this  page  was  positive  as  it  succinctly  covered  all  of  the  information  the   users  felt  they  needed  to  know  having  completed  the  process.       information  technologies  and  libraries  |  september  2015   53     figure  3.  feedback  for  the  “add”  button.     figure  4.  feedback  for  adding  multiple  authors  and  keywords.     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   54   modes  and  loops   the  final  two  components  of  microinteractions  defined  by  saffer  are  modes  and  loops.  saffer   describes  a  mode  as  a  “fork  in  the  rules,”  or  a  point  in  a  microinteraction  where  the  user  is   exposed  to  a  new  process,  interface,  or  state.23  for  example,  google  scholar  provides  users  with  a   setting  to  show  “library  access  links”  for  participating  institutions  with  openurl  compatible  link   resolvers.24  users  who  have  set  this  option  are  presented  with  a  search  results  page  that  is   different  from  the  default  mode  and  includes  additional  links  to  their  chosen  institution’s  link   resolver.  our  microinteraction  includes  two  distinct  modes.  once  logged  in,  users  can  choose  to   contribute  works  through  the  “do  it  yourself”  submission  that  we’ve  described  here  in  some   detail,  or  they  can  choose  “let  us  do  it”  and  complete  a  simplified  version  that  requires  them  to   acknowledge  the  licensing  agreement,  upload  their  files,  and  provide  any  additional  data  they   chose  in  a  free-­‐text  box  (see  figure  5).  the  majority  of  our  testers  specified  that  they  would  opt  for   the  “do  it  yourself”  option  because  they  wanted  to  have  control  over  the  metadata  describing   their  work,  including  the  abstract  and  keywords.  however,  since  launching  the  repository,  several   submissions  have  arrived  via  the  “let  us  do  it”  form,  which  suggests  a  reasonable  amount  of   interest  in  this  mode.     figure  5.  the  “let  us  do  it”  form.   loops,  on  the  other  hand,  are  simply  a  repeating  cycle  in  the  microinteraction.  a  loop  could  be  a   process  that  runs  in  the  background,  checking  for  network  connections,  or  it  could  be  a  more   visible  process  that  adapts  itself  on  the  basis  of  the  user’s  behavior.  for  example,  in  the  ro@m   submission  process  users  can  move  backward  and  forward  in  the  contribution  forms;  both  have     information  technologies  and  libraries  |  september  2015   55   “previous”  and  “save  and  continue”  buttons  on  each  page  to  allow  users  to  navigate  easily.  the   final  step  on  the  “do  it  yourself”  form  allows  users  to  review  their  metadata  and  the  file  that  they   have  uploaded.  they  can  then  use  the  previous  button  to  make  changes  to  what  they  have  entered   before  completing  the  submission.  ideally,  users  would  be  able  to  edit  this  content  directly  from   this  review  page,  but  software  constraints  prevented  us  from  including  this  feature,  and  the   “previous”  button  did  not  pose  any  major  challenges  for  our  testing  participants.  another  example   of  a  loop  in  ro@m  is  a  “contribute  more  works”  button  embedded  in  the  confirmation  screen  that   takes  users  back  to  the  beginning  of  the  microinteraction.  this  feature  was  suggested  by  one  of   our  participants,  and  it  extends  the  life  of  the  microinteraction,  potentially  leading  to  additional   contributions.   discussion  and  conclusions   focusing  on  the  details  of  the  self-­‐archiving  process  in  our  ir  provided  extremely  rich  qualitative   data  for  improving  the  user  interface,  while  analyzing  the  structure  of  the  microinteraction,   following  saffer’s  model,  was  also  a  valuable  exercise  in  thinking  about  user  needs  and  software   design  from  a  different  perspective  from  standard  usability  studies.  the  improvements  we  made,   based  on  both  saffer’s  theory  and  the  results  we  observed  through  testing,  added  significant   functionality  and  ease  of  use  to  the  self-­‐archiving  process  for  faculty.  thinking  carefully  about   elements  like  placement  of  buttons,  small  changes  in  wording  or  flow,  and  timing  of  instructional   or  error  feedback  highlighted  the  big  effect  small  elements  can  have  on  usability.     however,  there  are  some  limitations  to  both  the  theory,  and  our  approach  to  testing  and   improving  the  ir  that  affect  how  well  we  can  understand  and  utilize  the  results.  of  particular   concern  is  how  well  this  kind  of  testing  can  capture  the  ux  of  a  faculty  member  beyond  the  utility   or  ease  of  use  of  the  interaction.  in  an  observational  study  we  can  rely  on  comments  from   participants  and  key  statements  that  may  indicate  a  participant’s  emotional  or  affective  state,  but   we  didn’t  include  targeted  questions  to  gather  this  data  and  focused  instead  on  the  details  of  the   microinteraction.  we  didn’t  ask  how  they  felt  while  using  the  ir,  or  if  successfully  uploading  an   item  to  the  ir  gave  them  a  sense  of  autonomy  or  competence,  or  if  this  experience  would   encourage  them  to  submit  content  in  the  future.  nevertheless,  improving  usability  is  a  solid   foundation  for  providing  a  positive  ux.  hassahzhal  describes  the  difference  between  “do-­‐goals”   (completing  a  task)  and  “be-­‐goals”  (human  psychological  needs  like  being  competent,  or   developing  relationships).25  while  he  argues  that  “be-­‐goals”  are  the  ultimate  drivers  of  ux,  he  also   suggests  that  creating  tools  that  make  the  completion  of  do-­‐goals  easy  can  facilitate  the  potential   fulfillment  of  be-­‐goals  by  removing  barriers  and  making  their  fulfillment  more  likely.  ultimately,   however,  a  range  of  user  testing  strategies  can  lead  to  improvements  in  a  user  interface,  whether   that  testing  relies  on  carefully  detailed  examination  of  a  microinteraction,  analysis  of  large  data   sets  from  google  analytics,  or  interviews  with  key  user  groups.  microinteraction  theory  is  a  useful   approach,  and  valuable  in  its  conceptualization,  but  it  should  be  one  of  many  tools  libraries  adopt   to  improve  their  online  ux.     self-­‐archiving  with  ease  in  an  institutional  repository  |  betz  and  hall     doi:  10.6017/ital.v34i3.5900   56   similarly,  focusing  on  the  ux  of  irs  must  be  only  one  of  many  strategies  institutions  employ  to   improve  rates  of  faculty  self-­‐archiving.  there  have  been  recent  studies  that  argue  that  regardless   of  platform  or  process,  faculty-­‐initiated  submissions  have  proven  to  be  uncommon.26  instead,  they   suggest  that  sustainability  relies  on  marketing,  direct  outreach  with  individual  faculty  members,   and  significant  staff  involvement  in  identifying  content  for  inclusion,  investigating  rights,  and   depositing  on  authors’  behalf.  it  would  be  short  sighted  to  suggest  that  relying  solely  on  designing   a  user-­‐friendly  website,  or  only  developing  savvy  promotional  and  outreach  efforts,  can  determine   the  ongoing  success  of  an  ir  initiative.  gaining  and  maintaining  support  is  an  ongoing,   multifaceted  process,  and  largely  depends  on  the  academic  culture  of  an  institution  as  well  as   available  financial  and  staffing  resources.  as  such,  user  testing  offers  qualitative  insights  into  ways   that  processes  and  functions  might  be  improved  to  enhance  the  viability  of  ir  initiatives  in

and integration: embedding library resources in canvas articles collaboration and integration embedding library resources in canvas jennifer l. murray and daniel e. feinberg information technology and libraries | june 2020 https://doi.org/10.6017/ital.v39i2.11863 jennifer l. murray (jennifer.murray@unf.edu) is associate dean, university of north florida. daniel e. feinberg (daniel.feinberg@unf.edu) is online learning librarian, university of north florida. abstract the university of north florida (unf) transitioned to canvas as its learning management system (lms) in summer 2017. this implementation brought on opportunities that allowed for a more userfriendly learning environment for students. working with students in courses which were in-person, hybrid, or online, brought about the need for the library to have a place in the canvas lms. students needed to remember how to access and locate library resources and services outside of canvas. during this time, the thomas g. carpenter library’s online presence was enhanced, yet still not visible in canvas. it became apparent that the library needed to be integrated into canvas courses. this would enable students to easily transition between their coursework and finding resources and services to support their studies. in addition, librarians who worked with students, looked for ways for students to easily find library resources and services online. after much discussion, it became clear to the online learning librarian (oll) and the director of technical services and library systems (library director) that the library needed to explore ways to integrate more with canvas. introduction online learning is not a new concept at the unf. in fact, in-person, hybrid, and online courses used online learning in some capacity since distance learning took hold in higher education. unf transitioned to canvas as their learning management system (lms) in summer 2017, which replaced blackboard. this change, which affected all the unf’s online instruction and student learning, brought on new benefits and challenges that allowed for a more secure system for students to take in-person, hybrid, and distance learning courses. while this change occurred, unf’s library went through many changes in its virtual presence. students, specifically those who had classes that utilized canvas, needed a user-friendly way to use the library website and its resources virtually. in response, the library’s resources transitioned into having a greater online presence. however, ultimately, many students needed to use resources that they did not actually realize were available electronically from the library. through instruction and research consultations (both in-person and virtually), students needed to be directed back to the library homepage to access resources; however, the reality was that unless there was a presence of library instruction or professors pointing out library resources, students instead turned to google or other easy to find online resources to which they were previously exposed. how the project originated by spring 2018, there was growth of unf courses that were converted to online or hybrid courses. as students used canvas more, librarians started receiving feedback from in-person and online sessions that students had difficulty accessing the library’s resources while in canvas. the lack of library visibility in canvas caused the librarians to truly acknowledge that this was a problem. mailto:jennifer.murray@unf.edu mailto:daniel.feinberg@unf.edu information technology and libraries june 2020 collaboration and integration | murray and feinberg 2 students had to open a new browser window to access the library and then go back to canvas to complete their assignments, which involved multiple steps. this caused frustration among students who had to remember the library url, while also getting used to navigating their new courses in canvas. librarians consistently spent large amounts of time instructing students how to navigate to the library website during library instruction sessions and research consultations. in effect, more time was spent with students to guide them to library resources such as programmatic or course specific springshare hosted libguides (also known as library guides), or the library homepage. rather than being focused on how to use library resources and become more information literate, students spent more time on just locating the library website to get to the unf library’s online resources. together, the oll and library director talked about possibilities in canvas that would benefit all students who attended unf both in-person and online. canvas is located in unf’s mywings, a portal where all students go for coursework, email, and resources that support their academic studies at unf. it became apparent that if it was possible, there needed to be a quicker way to access the unf library resources for students. literature review with the advent of online learning, it became obvious that students needed to have library access within their online learning management system. for campuses such as unf, this meant within canvas. for unf students that are distance or online students only, this was especially true. farkas noted that librarians had worked to determine the best ways to provide library materials, services, and embed librarians into the lms.1 over the last fifteen years, lms have become more important to support the growth of online learning. pomerantz noted that the lms has become critical to instruction and online learning. approximately 99 percent of institutions adopt an lms and 88 percent of faculty utilize an lms platform.2 this “puts it in the category with cars and cellphones as among the most widely adopted technologies in the united states.”3 library guides that have been integrated into an lms increased their visibility, but did not guarantee that faculty and students would utilize them. that is why it was critical to continuously collaborate and communicate with faculty, students, and librarians to bring attention to the resources that could assist students. farkas noted that librarians at the ohio state university discussed that no matter how the library was integrated into a university’s lms, the usage of the library there was decidedly dependent on if the faculty professor promoted the library to their students.4 the reality that libraries faced was that without visibility in an lms, students that were online/distance learners needed to remember or find the library’s website. while this seemed to be inconsequential, it caused students to use google or other resources instead of their university/college’s library discovery tool or library databases. farkas noted that shank and dewald’s seminal article described a university’s lms as having two levels, macro and micro. when there was one way to access the library in the lms, then it was termed macro. this single pathway allowed for less maintenance since there was a single way to access the library from the lms.5 the university of kentucky embedded the library by adding a library tab in blackboard. other institutions like portland state university, ohio state university, and oakland state university developed library widgets to make the library more accessible.6 the addition of library and research guides in library instruction was critical to increase visibility for information technology and libraries june 2020 collaboration and integration | murray and feinberg 3 students and furthermore make sure students had easier access to the library through their lms. getting librarians’ access to the lms at their institutions is an ongoing issue.7 unf librarians wanted to determine best practices to decide how the library could integrate into canvas. therefore, research was needed to see what other university libraries were doing. the librarians at unf discovered that there was no obvious preference based on examples found in research to accomplish how to get the library into canvas. davis observed that “claiming a small amount of real estate in the lms template . . . is an easy way to put the library in students’ periphery.” by simply having a library link added or a page added to each course was “the digital equivalent for students of walking past the library on the way to class.”8 however, it seemed that a lot depended on how an lms was used at an unf and the technical expertise available. thompson and davis noted that the “lms technology has added another layer of complexity to the puzzle. as technology evolves to address changes in learning design, student and facu lty attitudes, expectations, perceptions will continue to be a critical piece of the course integration puzzle.” 9 while looking at other institutions, there were a variety of ways in which canvas and the library were integrated. there were numerous examples from embedded springshare product library guides, to the creation of modules of quizzes or tutorials, and even to the creation of online minicourses, and embedded librarians in lms courses.10 penn state university looked at their method of how to add library content into canvas. they already had a specific way of putting library guides in canvas, but it was not in a highly visible location for students to easily access. when faculty put guides in their courses, with the collaboration of librarians, the guides were used. however, many of the faculty did not use these librarians or resources. a student survey and user studies were used to best learn how to fix the problem of students and faculty that did not use the guides and content more. penn state worked with their comm 190 instructors to administer a survey that was extra credit, to ensure getting responses.11 “general findings included: 53 percent of students did not know what a course guide was; 41 percent of students had used a guide for a class project; 60 percent accessed a course guide via the lms; and 37 percent of students used course guides on their own.”12 many students were interested in doing their library research within canvas itself. it should be noted that the guides needed to be in a prominent place in canvas, but not overwhelm the course content. for course-specific guides an introductory statement was needed to describe what the guide was about. when the release of springshare’s lti tool occurred, it became an optimal time in which the technical solutions allowed for penn state’s library guides to be embedded smoothly into canvas.13 the learning tools interoperability (lti tool) allows for online software to be integrated into canvas. in effect, when professors want to add a tool to their course, it allows for more seamless and controlled avenue. in the case of library guides, it creates a way in which guides can be embedded into the lms with little problems. another example of a library integration into a campus lms was at the utah state university (usu) merrill-cazier library. they looked to find a way to maximize the effectiveness of springshare’s library guides when they assessed the design and reach of library guides within their lms.14 they took a unique approach to build an lti tool that automatically pulled in the most appropriate library guide when the “research help” link in canvas was activated by a professor. they also saw this as an opportune time to redesign their subject guides and ensure there were guides for all disciplines. they provided usage data to subject librarians to help determine where there might be opportunities to interact with classes and provide more library instruction. overall, information technology and libraries june 2020 collaboration and integration | murray and feinberg 4 the study and feedback they received from students helped them to find ways to improve how librarians used and thought about library guides, and expanded their reach based on usage data. 15 this ability to add library guides to canvas provided students a way to access library materials or the library without having to leave the online classroom. many libraries have conducted focus groups and usability studies that were key to providing valuable feedback on the knowledge and understanding that faculty and students had of guides, ways to improve information shared that assisted students with their coursework and faculty in their online teaching. research indicated that exploration and implementation of integrating library guides into an lms led to a need to improve and provide more consistently designed guides.16 the literature indicated the importance of a strong relationship with the department that manages the lms. these integrations were made much easier when there was a relationship established and it sometimes led to finding out about additional opportunities to integrate more with the lms. penn state saw an increase of over 200,000 hits to its course guides believed to be because of the lti integration.17 this, however, did not guarantee that the students benefited from the course guides, similar to library statistics not proving resources were being used despite page hits. in addition, faculty were able to turn off the lti course guide tool, which reduced the chances of student usage or awareness of the course guide. based on feedback from students and faculty, it did not matter where the course guides were since they could be ignored anyway. a penn state blog was developed by the teaching and learning with technology unit to provide instructors a venue in which they could be aware of online services that librarians provide.18 “although automatic integration allows specialized library resources to be targeted at all lms courses, that does not mean that they’ll be accessed. it is important then to build ongoing relationships with stakeholders, providing not just information that such integrations exist, but also reasons why to use them.”19 however, not all universities and colleges decided to integrate the library strictly through a library guide or a link to the library integration into their lms. karplus noted that students spent more time online rather than going to the physical academic library. karplus discussed that the digital world combined with academic library resources had two benefits. one of which brought online research as a more normal occurrence. the second benefit was that students were more comfortable with accessing online resources.20 while using blackboard, st. mary’s college’s goal was to incorporate library information literacy modules into courses that existed. using the blackboard lms, students were able to access all components of their courses including assigned readings. this became their academic environment. therefore, information literacy modules, tutorials, and outside internet resources could be added to the lms.21 tutorials combined with preand post-testing, gave faculty instant feedback. librarians were also able to participate in blackboard through discussion boards and work with students.22 there was a constant need to update the modules and the information added to blackboard. librarians having access to the blackboard site, allowed for students to use the library resources more readily. “the site can be the focal point for many librarians in one location thus ensuring a consistent, collaborative instructional program.”23 overall, the integration of campus librarians into an lms was to get students to use the library in order to be more successful in their academic endeavors. information technology and libraries june 2020 collaboration and integration | murray and feinberg 5 developing a plan of action initially, the oll and library director brainstormed possible integration ideas, ranging from adding a library global navigation button to the canvas ui, to adding a link to the library in the canvas help menu. at the same time, they also researched what other libraries had done. after brainstorming, it was realized that additional conversations needed to occur within the library and with unf’s online learning support team, a part of the center for instruction and research technology (cirt), the group that manages canvas. the discussion to integrate the library and canvas was a complex matter. unf administrators asked for a proposal to be written so it could be brought to the library, online learning support team, and information technology services (its) stakeholders for discussion and approval. that proposal, along with much needed discussion, was critical in order to determine the possibilities and actions that needed to be taken. that being said it was important to recognize the importance of what was best to serve the faculty and students. when brainstorming discussions started to occur with unf’s online learning support team, it was important for the library to determine what options were available to embed the library in canvas. the library had a strong relationship with unf’s online learning support team and its administrators, which made this an easy process to pursue. what the oll and library director initially wanted was to add a simple link to the global navigation in canvas that would take all users to the library homepage. however, it became apparent that this was not possible due to the fact that this space is limited and many departments on campus would like greater visibility in canvas. the next option, which was easier to implement, was to add a link to the library homepage under the help menu in canvas. although this menu link was added, it was so hidden in canvas that the oll and library director felt that it would never be found in canvas by faculty, let alone students. cirt administrators asserted to the oll and library director of what other possibilities were available. after researching options, the library recommended creating access to library resources and services using a springshare lti tool for library guides, which cirt agreed to. library guides, or libguides, are library webpages that are built from springshare software. using the lti tool seemed like a great possibility since it would allow for more of a presence in addition to the help link to the library homepage. after approval from library administration and initial discussions with it, the project moved forward. implementation the project took about a year to complete from the time discussions began internally in the library to the time the integration went live (see figure 1). information technology and libraries june 2020 collaboration and integration | murray and feinberg 6 figure 1. project timeline the idea to have a seamless entryway to the library seemed to be a good idea based on observations and feedback from students, but the oll and library director started by completing an environmental scan to see what other institutions did to get ideas on ways the unf library could integrate into canvas. the oll and library director learned that there were a variety of ways it had been done from the integration of the library at the global navigation level, course level, and by an added link to the library under the help menu in canvas. it became clear that an integration into canvas would seem like an obvious progression to strengthen not only online learning, but also give students the ability to benefit from the resources that the library subscribed to and enhance their curricular needs. conversations then occurred with unf’s online learning support team to discuss integration options further. after much discussion, a decision was made to pursue an added link to the librar y website under the canvas help menu and a new lti tool at the course level. since canvas was used in so many courses, it was determined that university-wide campus committee agreement was needed on how to go about adding library guides to canvas courses. librarians were also approached at this time to get their input and feedback. the goal seemed obvious to the librarians. when they were approached, buy-in to support the students with canvas by way of the help button and lti tool integration seemed more than straightforward. therefore, for the librarians, the goal was to solve the problem of making sure that students could easily access library materials. overall, the library faculty’s preference for the implementation was to embed the library website under the canvas help menu while also have the student resources libguide inside all canvas courses using the springshare lti tool. after all internal approvals were obtained, the link to the library was seamlessly added under the canvas help menu. as for the springshare lti tool, it required more work and discussion before it could be implemented. after approval was granted from the unf online learning support team and campus its security team, the integration began. configuration options for the lti tool were explored and the systems and digital technologies librarian worked closely with the unf online learning support team and springshare to setup the libapp lti tool. information technology and libraries june 2020 collaboration and integration | murray and feinberg 7 the first step was to configure springhare’s automagic lti tool to automatically add libguid es to courses in canvas. this included adding an lti tool name and description, which appeared in canvas during setup and the course navigation. it was also decided to set the student resources libguide as the default guide for all courses based on feedback from across campus. instructors could request to use a different libguide for their course. to enable this, two parameters had to be set in the automagic lti tool to enable libguide matching between canvas and libguides: • lti parameter name: for unf, this was set to “context” label, to select the course code field in canvas. • libguides metadata name: this was set to the appropriate value to identify the metadata field used in libguides. if an instructor decided to change the default guide to another guide, these two parameters would need to be entered into a specific libguide’s custom metadata, so that canvas could link to the designated guide to display in a course. the change had to be made in the libguide itself, so it was handled by the systems and digital technologies librarian. there had not been many instructors who had requested this yet, but if utilized, the library would also have had to ensure this carried over each semester by updating the metadata in the guide to the new course code. after the configuration was completed on the springshare side, the next step was to set up the integration in the canvas test environment. an external application had to be installed in canvas to allow the springshare lti tool to run. after it was tested, the application was applied across all courses and set to display by default, which the majority of faculty preferred. faculty who did not want to use the integration had the ability to manually turn it off in canvas. during the implementation setup, a few minor issues were encountered. after seeing what the student resources guide looked like in canvas it became clear that the header and footer were not needed and just cluttered the guide. they were both removed in the lti setup options to ensure a cleaner looking guide. since the libguides were being embedded into another system (canvas), formatting of the guides had to be adjusted. the other issue encountered was trying to add available springshare widgets such as the library hours or room booking content to the guide using the automagic lti tool. while this was not successful, it was determined that the additional options were not needed. once the integration was set up in the canvas test environment, demonstrations were held and input was gathered from stakeholders through campus-wide meetings with faculty to obtain their input. it was critical to determine if faculty would utilize libguides in their canvas courses. an overview of the integration and the benefits were given to the campus technology committee and distance learning committee faculty. a demonstration was also given so that these faculty committees could see what the integration would look like in their courses. overall, the feedback obtained from the faculty was very positive. the preference was to have the configuration be optout, where the library guides would automatically display in canvas courses. many faculty members were excited about the integration and looked forward to having it in their courses. after demos took place and final setup was completed based on feedback, the integration was then setup in the canvas production environment and was announced via newsletters, emails , and social media. as of the fall 2019 semester, the library's student resources guide was integrated into all courses in canvas (see figure 2). information technology and libraries june 2020 collaboration and integration | murray and feinberg 8 figure 2. student resources library guide in canvas benefits of the integration students are dependent on their campus lms in order to complete their coursework, support their studies, and in the case at unf, have easier access to the online campus. the libguide integration not only streamlined their way to library resources, but also promoted library usage from students that may not have known how to get to the resources available to them. for faculty it should be noted that they were able to replace the default student libguide with a more specific subject or course guide. either way, it brought more awareness to resources and services that supported curricular needs. the springshare chat widget in the guide also gave students the ability to communicate directly with a librarian from within canvas. this integration not only increased the library visibility in the online environment but enabled all students, whether inperson, hybrid, or online, with direct access to the resources they needed for their coursework. challenges of the integration although there were many benefits to integrate the library into canvas, there were many challenges with making the integration happen. there were many more stakeholders than expected. from library administration, to the canvas administrators, to library faculty, and teaching faculty committees, their input was needed prior to the project taking place. since the project grew organically, this meant that all of the stakeholders were brought in as the project grew or unfolded. once the project received approval from the library and cirt administrators, its administrators had to give the final approval in order to proceed with the integration of library guides. the process to implement the integration took some time to figure out. in addition, getting buy-in from the teaching faculty was key as the navigation options in their canvas courses would be impacted. making sure the faculty understood how it would assist their students was important as the goal was to help their students succeed with their coursework. information technology and libraries june 2020 collaboration and integration | murray and feinberg 9 a concern was if faculty would tell their students, or conversely, would students find the link to the libguide on their own? determining how the news of the library and canvas integration would be communicated to the unf community was the final step. the library director, oll, and cirt administrators needed to determine the best communication routes to get the unf community aware of this news. in effect, emails, unf updates/newsletters, and by word of mouth by teaching faculty. it was crucial that students be aware of these tools. this meant that going forward, unf would depend on word of mouth or student's curiosity in the canvas navigation bars themselves. discussion and next steps integrating the library with the unf’s learning management system, canvas, took much planning and collaboration, which was key to creating a more user-friendly learning environment for students. in reflecting on what went well and what did not, the unf librarians learned several important lessons that will help improve upon the implementation of future projects. to begin, it is important to identify and involve stakeholders early on, so they can provide feedback along the way. getting buy-in from the teaching faculty is also key since the integration affects the navigation options in their canvas courses. for unf, initially, the oll and library director did not realize how many groups of teaching faculty and departments would need to approve this canvas change and implementation. it was important to have them understand the importance of the integration and how it can assist their students with their coursework. considering the content of the library guides was important because of the impact it would have on canvas courses. for example, at the unf library some students thought that the librarian’s picture on the default guide was in fact their professor. in turn, students began to contact her. this caused much confusion for our students and professors alike. along the way, communication is critical so that everyone is kept informed as the integration progresses. communication at the appropriate times and ensuring all information is gathered about configuration options before starting conversations with stakeholders is important too. having this transparency at the appropriate times and ensuring there was enough info rmation about the configuration options before starting conversations with stakeholders was important too. finally, investigating the ability to retrieve usage statistics from day one would be extremely beneficial and provide data to assess how often the library guides are being used in the lms and by whom. this information would help determine next steps and explore other potential integration opportunities. at unf, the librarians were not able to implement statistics as part of our integration which has made it more difficult to assess the usage of the library guides in canvas. now that the integration has been completed, ensuring the integration continues to meet the needs of faculty and students will be important. feedback will need to be gathered from stakeholders to find out if they find the integration useful, if there are any issues being encountered, and/or if they have any recommendations for ways to enhance the integration. usage statistics will also be gathered as soon as they are available. this will provide information on which instructors are using the library guides in their courses and which instructors are not using them. for those who have used it, it will be an opportunity to target those courses for instruction. for those who have not used them, it will be an opportunity to find out why and make sure they are aware of the benefits of using them in their courses. information technology and libraries june 2020 collaboration and integration | murray and feinberg 10 exploring other integration possibilities, especially as the technology continues to evolve, will be important to ensure the library continues to reach students. while the natural progression of the unf integration would be to embed librarians in the canvas platform, others have faced challenges. “according the ithaka s & r library survey 2013 by long and schonfeld, 80–90 percent of academic library directors perceive their librarians’ primary role as contributing to student learning while only 45–55 percent of faculty agree librarians contribute to student learning.”24 even though this is a challenge, faculty collaboration with librarians is crucial for the embedded librarian role. without a requirement of embedded librarianship, marketing for the librarians and what they can do for students will be essential for their role to be successful.25 at unf, conversations will have to be held to determine what other integrations would be of interest and possible at our university. the unf library will also be looking to improve the design and layout of library guides. now that their visibility has increased, it will be important to standardize them and ensure they all have a consistent look and feel, which will make it easier for students to find the information and resources they are looking for. conclusion in today’s rapidly changing technological world, it is critical to make resources available despite where students are physically located. integrating the library’s libguides into canvas not only brought more visibility to the library, its resources, and its services, but it also brought the library to where the students were engaged with the university. as noted by farkas, “positioning the library at the heart of the virtual campus seems as important as positioning the library as the heart of the physical campus.”26 providing resources to students at their point of need, enabled them to easily access the information they needed to help them succeed in their courses. it also allowed faculty to integrate library resources that were most beneficial to their courses and enhanced their teaching as well as the educational needs of their students. the unf library will continue to look at how library resources are used, and how to best serve the online community going forward. it will be important to explore ways to enhance existing services with existing technology but also look ahead and determine what may be possible down the road with new and upcoming technologies. in addition, assessing how the library connects to online learners and gathers feedback from students and faculty will be critical to contributing to the success of students. endnotes 1 meredith gorran farkas, “libraries in the

usability testing with ten student testers to establish recommendations and guide the migration process from libguides version 1 to version 2. this case study describes the results of the testing as well as raises additional questions regarding the general effectiveness of libguides, especially when students rely heavily on search to find library resources. introduction guides designed to help users with research have long been included among a suite of reference services offered by academic libraries, though terminology, formats, and mediums of delivery have evolved over the years. print “pathfinders,” developed and popularized by the model library program of project intrex at mit in the 1970s, are the precursor to today’s online research guides, now a ubiquitous resource featured on academic library websites.1 pathfinders were designed to function as a “kind of map to the resources of the library,” helping “beginners who seek instruction in gathering the fundamental literature of a field new to them in every respect” find their way in a complex library environment.2 with the advent of the internet, pathfinders evolved into online “research guides,” which tend to be organized around subjects or courses. in the late 1990s and early 2000s, creating guides online required a level of technological expertise that many librarians did not possess, such as html-coding knowledge or the ability to use web development applications like adobe dreamweaver. as a result, many librarians could not create their own online guides and relied upon webmasters to upload and update content. the online guide landscape changed again in 2007 with the introduction of springshare’s libguides, a content management solution that quickly became a wildly popular library product.3 as of december 2018, 614,811 guides had been published by 181,896 librarians, at 4,743 institutions in 56 countries.4 the popularity of libguides is due in part to its removal of technological barriers to online guide creation, making it possible for those without web-design experience to create content. libguides is also a particularly attractive product for libraries constrained by campus or library web templates, affording librarians and library staff the freedom to design pages without requiring higher level permissions to websites. despite these advantages, in the absence of oversight, libguides sites can develop into microsites within the library’s larger web presence. inexperienced content creators can inadvertently develop guides that are difficult to use, lacking consistent templates and containing overwhelming amounts of information. as a result, libraries mailto:suzanna.conrad@csus.edu mailto:crstevens@sfsu.edu am i on the library website? | conrad and stevens 50 https://doi.org/10.6017/ital.v38i3.10977 often find it useful to develop local standards and best practices in order to enhance the user experience.5 like many academic libraries, the cal poly pomona university library uses the libguides platform to provide the campus community with course and subject guides. in 2015, librarians began discussing plans to migrate from libguides version one to the version two platfo rm. these discussions led to broader conversations about libguides related issues and concerns, some of which had arisen during website focus group sessions conducted in early 2015. the focus groups were designed to provide the library with a better understanding of students’ library website preferences. students reported frustration with search options on the library website as well as confusion regarding inconsistent headers. even though focus group questions were related to the library website, two participants commented on the library’s libguides as well. the library was using a modified version of the library website header for vendor-provided services, including libguides, so it was sometimes unclear to students when they had navigated to an external s ite.6 to complicate matters, the library also occasionally used libguides for other, non-researchrelated library pages, such as a page delineating the library’s hours, because of the ease of updating that the platform affords. one student, who had landed on the libguides page detailing the library’s hours, described feeling confused about where she was on the library website. she explained that she had tried to use the search box on the libguides page to navigate away from the hours page, apparently unaware that it was only an internal libguides search. as a result, she did not receive any results for her query. the language the student used to describe the experience clearly revealed her disorientation and perplexity: “something popped up called libguides and then i put what i was looking for and that was nothing. it said no search found. i don’t even know what that was, so i just went to the main page.” another participant, who also tried to search for a research-related topic after landing on a libguides page, stated, “i tried putting my topics. i even tried refining my topic, but then it took me to the guide thing.” accustomed to using a search function to find information on a topic, this student did not interpret the research guide she had landed upon as a potentially useful tool that could help with her research. she expected that her search would produce search results in the form of a list of potentially relevant books or articles. the appearance instead of a research guide was misaligned with her intentions and expectations and therefore confusing to her.7 given both the libguides related issues that emerged during the library website focus groups and the library’s plan to migrate from libguides version one to version two in the near future, the library’s digital initiatives librarian and head of reference and instruction decided to conduct usability testing focused specifically on libguides. in addition to testing the usability of specific libguides features, such as navigational tabs and subtabs, we were also interested in determining whether some of the insights gleaned from the library website focus groups and from prior user surveys and usability testing regarding users’ web expectations, preferences, and behaviors were also relevant in the libguides environment. specifically, prior data had indicated users were unlikely to differentiate between the library’s website and vendor-provided content, such as libguides, libanswers, the library catalog, etc. findings also suggested that rather than intentionally selecting databases that were appropriate to their topics, students often resorted to searching in the first box they saw. this included searching for articles and books on their topics using search boxes that were not designed for that purpose, such as the database search box on the library’s a-z database page and the libguides site search tool for searching all guides. although many students did not always resort to searching first (many did attempt to browse to information technology and libraries | september 2019 51 specific library services), if they were not immediately successful, they would then type terms from the usability testing task into the first available search box.8 finally, we were also aware that many of our current libguides contained elements that were inconsistent with website search and design best practices as well as misaligned with typical website users’ behaviors and expectations, as described by usability experts like jakob nielsen. as such, we wanted to test the usability of some of these potentially problematic elements to determine whether they negatively impacted the user experience in the libguides environment. if they did, we would have institution-specific data that we could leverage to develop local recommendations for libguides standards and best practices that would better meet students’ needs. literature review the growth of libguides since springshare’s founding in 2007, libguides have been widely embraced by academic libraries.9 in 2011, ghaphery and white visited the websites of 99 arl university libraries in the united states and found that 68 percent used libguides as their research guides platform. they also surveyed librarians from 188 institutions, 82 percent of which were college or university libraries, and found that 69 percent of respondents reported they used libguides.10 as of december 2018, springshare’s libguides community website indicated that 1,620 academic libraries in the united states and a total of 1,823 academic libraries around the world, not counting law and medical libraries, were using the libguides platform.11 libguides’ popularity is due in part to its user-friendly format, which eliminates most technical barriers to entry for would be guide authors. for example, anderson and springs surveyed librarians at rutgers university and found they were more likely to update and use libguides than previous static subject guides that were located on the library website and maintained by the webmaster, to whom subject specialists submitted content and any needed changes.12 the majority of librarians reported that having direct access to the libguides system would increase how often they updated their guides. moreover, after implementing the new libguides system, 52 percent said they would update guides as needed, and 14 percent said they would update guides weekly; prior to implementation, only 36 percent stated they would update guides as needed, and none said they would do so weekly. libguides usability testing and user studies although much literature has been published on the usability of library websites,13 fewer studies have focused on research guides or libguides specifically. of these, several focused on navigation and layout issues. for example, in their 2012 libguides navigation study, pittsley and memmott confirmed their initial hypothesis that the standard libguides navigation tabs located in a horizontal line near the top of each page can sometimes go unnoticed, a phenomenon referred to as “banner blindness.” as a result of their findings, librarians at their institution decided to increase the tab height in all libguides, and some librarians also chose to add content menus on the homepages of each of their guides. they moved additional elements from the header to the bottom of the guide under the theory that decreased complexity would contribute to increased tab navigation recognition.14 sonsteby and dejonghe examined the efficacy of libguides’ tabbed navigational interface as well as design issues that caused usability problems. they identified user preferences, su ch as users’ am i on the library website? | conrad and stevens 52 https://doi.org/10.6017/ital.v38i3.10977 desire for a visible search box that behaved like a discovery tool, and design issues that frequently led to confusion, such as search boxes that searched for limited types of content, like journal titles. they also found that jargon confused users, and that guides containing too many tabs that were inconsistently labeled led to both confusion and the perception that guides were “cluttered” and “busy.”15 thorngate and hoden explored the effectiveness of libguides version two designs, specifically focusing on use of columns, navigation, and the integration of libguides into the library website. they found that two-column navigation is the most usable, users are more likely to notice left navigation over horizontal tabs, and students do not view libguides as a separate platform, expecting instead for it to live coherently within the library’s website. 16 almeida and tidal employed a mixed methods approach to gather user feedback about libguides, including usage of “paper prototyping, advanced scribbling, task analysis, tap, and semi-structured interviews.”17 the researchers intended to “translate user design and learning modality preferences into executable design principles,” but found that no one layout filled all students’ needs or learning modalities.18 ouellette’s 2011 study differed from many libguides-focused articles in that rather than assigning participants usability tasks, it employed in-depth interviews with 11 students to explore how they used subject guides created on the libguides platform and the features they liked and disliked about them. like some of the aforementioned studies, oullette found that students did not like horizontal tabbed navigation, preferring instead the more common left-side navigation that has become standard on the web. however, the study was also able to explore issues that many of the usability task-focused studies did not, including whether and how students use subject guides to accomplish their own research-related academic work. ouellette found that students “do not use subject guides, or at least not unless it is a last resort.”19 reasons provided for non-use included not knowing that they existed, preferring to search the open web, and not perceiving a need to use them, preferring instead to search for information rather than browsing a guide.20 such findings call into question the wisdom of expending time and resources on creating guides. however, ouellette asserted that students were more likely to use research guides when they were stuck, when they were required to find information in a new discipline, or when their instructors explicitly suggested that they use them.21 nevertheless, most students who had used libguides reported that they had done so solely “to find the best database for locating journal articles.”22 indeed, ouellette found that the majority of “participants had only ever clicked on the tab leading to the database section of a guide,” a finding that was consistent with staley’s 2007 study, which found that databases are the most commonly used subject guide section.23 while ouellette concluded that libguides creators should therefore emphasize databases on their guides, both the more recent widespread library adoption of discovery systems that search across databases, in many cases making it unnecessary for students to select a specific database, as well as the common practice of aggregating relevant databases under disciplinary subject headings on library databases pages implicitly call into question the need for duplicating such information on library subject guides. if users can easily find such information elsewhere, these conclusions also cast doubt on the effectiveness of the entire libguides enterprise. information retrieval behaviors: search and browse preferences in 1997, usability expert jakob nielsen reported that more than half of web users are “search dominant,” meaning that they go directly to a search function when they arrive at a website rather than clicking links. in contrast, only a fifth of users are “link dominant,” preferrin g to navigate sites by clicking on links rather than searching. the rest of the users employ mixed strategies, switching information technology and libraries | september 2019 53 between searching and clicking on links in accordance with what appears to be the most promising strategy within the context of a specific page.24 while some researchers have questioned the prevalence of search dominance, nielsen’s mobile usability studies have indicated an even stronger tendency toward search dominance when users access websites on their mobile devices.25 moreover, by 2011, nielsen’s research had indicated that search dominance is a user behavior that gets stronger every year, and that “many users are so reliant on search that it’s undermining their problem-solving abilities.” specifically, nielsen found that users exhibited an increasing reluctance to experiment with different strategies to find the information they needed when their initial search strategy failed.26 nielsen attributes the search dominance phenomenon to two main user preferences. the firs t is that search allows users to “assert independence from websites’ attempt to direct how they use the web.”27 the second is that search functions as an “escape hatch when they are stuck in navigation. when they can’t find a reasonable place to go next, they often turn to the site’s search function.” nielsen developed a number of best practices based on these usability testing results, including that search should be made available from every page in a website, since it is not possible to predict when users will feel lost. additionally, given that users quickly scan sites for a box where they can type in words, search should be configured as a box and not a link, it should be located at the top of the page where users can easily spot it, and it should be wide enough to accommodate a typical number of search terms.28 nielsen’s usability studies have shed light not only on where search should be located but also on how search should function. in 2005, nielsen reported that searchers “now have precise expectations for the behavior of search” and that “designs that invoke this mental model but work differently are confusing.”29 specifically, searchers’ “firm mental model” for how search should work includes “a box where they can type words, a button labeled ‘search’ that they click to run the search, [and] a list of top results that’s linear, prioritized, and appears on a new page.” moreover, nielsen found that searchers want all search boxes on all websites to function in the same way as typical search engines and that any deviation from this design causes usability issues. he specifically highlighted scoped searches as problematic, pointing out that searches that only cover a subsite are generally misleading to users, most of whom are unlikely to consider what th e search box is actually searching.30 while there is much evidence to support nielsen’s claims about the prevalence of search dominance, other studies have suggested that users themselves are not necessarily always search or link dominant. rather, some websites lend themselves better to searching or exploring links, and users often adjust their behaviors accordingly.31 although we did not find studies that specifically discussed the search and browse preferences and behaviors of libguides users, we did find studies of library website use that suggested that though users often exhibit search -dominant tendencies, they also often rely on a mixed approach to library website navigation. for example, hess and hristova’s 2016 study of users’ searching and browsing tendencies explored how students access library tutorials and online learning objects. specifically, they compared searching from a search box on the tutorials landing page, using a tag cloud under a search box, and browsing links.32 google analytics data revealed that students employed a mixed approach, equally relying upon both searching and clicking links to access the library’s tutorials.33 similarly, han and wolfram analyzed clickstream data from 1.3 million sessions in an image repository and determined that the two most common actions (86 percent of actions) were simple search and am i on the library website? | conrad and stevens 54 https://doi.org/10.6017/ital.v38i3.10977 click actions.34 however, users in this study exhibited a tendency toward search dominance, conducting simple searches in 70 percent of the actions.35 niu, zhang, and chen presented a mixed methods study analyzing search transaction logs and conducting usability testing f ocused on comparing the discovery layers vufind and primo. browsing in the context of their study included browsing search results. they found that most search sessions were very brief, and students searched using two or three keywords.36 xie and joo tested how thirty-one participants went about finding items on a website, classifying their approaches into what they described as eight “search tactics,” including explorative methods, such as browsing.37 over 88 percent of users conducted at least one search query, and 75 percent employed “iterative exploration,” browsing and evaluating both internal and external links on the site “until they were satisfied or they quit.”38 only four of thirty-one, or 6.7 percent, did “whole site exploration,” a tactic which included browsing and evaluating most of the available information on a website, looking through every page on the site to find the desired information.39 method this study addresses the following research questions: 1. when prompted to find a research guide, are students more likely to click links or type terms into a search box to find the guide? 2. are students more likely to successfully accomplish usability tasks directing them to find specific information on a libguide when using a guide with horizontal or vertical tabs? 3. how likely are students to click on subtabs? 4. how and to what extent does a one-, two-, or three-column content design layout affect students’ ability to find information on a libguide? 5. how and to what extent do students use embedded search boxes in libguides? 6. do students confuse screenshots of search boxes with functioning search tools? in 2015, the university library had access to two versions of libguides: the live version one instance and a beta version two instance. in order to answer our research questions and make data-informed design decisions that would improve the usability of our libguides, we compared the usability of existing research guides in libguides version one to test sites on libguides version two. version two guides differed from version one guides in several ways. version two guides were better aligned with nielsen’s recommendations regarding search box placement and function. every libguide page included a header identical to the library website’s header, which contained a global search box that searched both library resources and the library’s website. the inclusion of a visible discovery tool in the header was consistent with usability recommendations in the literature40 as well as our own prior library website usability tests, which indicated many users preferred searching for resources over finding a path to them by clicking through a series of links. in mid-april 2015, ten students were scheduled to test libguides. each student attempted the same seven tasks, but five students tested the current version of libguides and five students tested version two. the sessions were recorded using camtasia, and students completed usability tasks on a laptop that was hooked up to a large television monitor, allowing the two librarians who were in the room to observe how students navigated the library’s website and libguides platform. one librarian served as the moderator and the other managed the recording technology.41 although additional members of the web team were interested in viewing the test information technology and libraries | september 2019 55 sessions, in order to avoid overwhelming the students, only two librarians sat in the sessions. the moderator read tasks aloud and students were instructed to think aloud while completing each task, narrating their thought processes and navigational decisions. students were recruited via a website usage and perceptions survey sent out the prior quarter, which included a question as to whether they would be interested in participating in usability testing. the students who received this survey were selected from a randomized sample provided by the university’s institutional research office. the sample included both lower division students in the first or second year of their studies and transfer students. students were also recruited in information literacy instruction sessions for lower-level english courses as well as in a creditbearing information literacy course taught by librarians. survey respondents and students from the targeted classes who indicated that they would be interested in participating in usability testing were subsequently contacted via email. students with appropriate testing day availability were selected. students from the various colleges were represented, including engineering; business administration; letters, arts and social sciences; education and integrative studies; and hospitality management. all of the participants were undergraduates and most were lower division students. we chose to focus on recruiting lower division students because we wanted to ensure that our guides were usable by students with the least amount of library experience; many lower division students are unaware of library services and may not have taken a library instruction session or a library information literacy course. however, while the goal was to recruit lower division students, scheduling difficulties, including three no-shows, led us to recruit students on-the-fly who were in the library, regardless of their lower division or upper division status. task 1 in both rounds of usability testing, students were prompted to find a “research guide” to help them write a paper on climate change for a com 100 class. students started from the homepage of the library. two possible success routes included browsing to a featured links section on the homepage where a “research guides” link was listed (see figure 1) or searching via the top level “onesearch” discovery layer search box, displayed in figure 2, which delivered results, including articles from databases, books from the catalog, library website pages, and libguides pages, in a bento-box format. the purpose of this task was to determine if students browsed or searched to find research guides. we defined browsing as clicking on links, menus, or images to arrive at a result, whereas searching involved typing words and phrases into a search box. am i on the library website? | conrad and stevens 56 https://doi.org/10.6017/ital.v38i3.10977 figure 1. featured links section on library homepage. figure 2. onesearch search box on library homepage. task 2 task 2 was designed to compare the usability of libguides version one’s horizontal tab orientation with version two’s left navigation tab option. students were provided with a scenario in which they were asked to compare two public opinion polls on the topic of climate change for the same com 100 class. we displayed the appropriate research guide for the students and instructed them to find a list of public opinion polls. the phrase “public opinion polls” appeared in the navigation of both versions of the guide. figure 3 displays the research guide with horizontal tab navigation and figure 4 with vertical, left tab navigation. information technology and libraries | september 2019 57 figure 3. horizontal tab navigation. am i on the library website? | conrad and stevens 58 https://doi.org/10.6017/ital.v38i3.10977 figure 4. left tab navigation. task 3 in the third scenario, students were informed that their professor recommended that they u se a library “research guide” to find articles for a research paper assignment in an apparel merchandising and management class. students were instructed to find the product development articles on the research guide. the phrase “product development” appeared as a subtab in both versions of the guide. this task was intended to test whether students navigated to subtabs in libguides. as shown in figure 5, the subtab located on the horizontal navigation menu appeared when scrolled over but was otherwise not immediately visible. in contrast, figure 6 shows how the navigation was automatically popped open on the left tab navigation menu so that subtabs were always visible, a newly available option in libguides version two. figure 5. horizontal subtab options. information technology and libraries | september 2019 59 figure 6. left tab navigation with lower subtabs automatically open. task 4 on the same apparel merchandising and management libguide, students were asked where they would go to find additional books on the topic of product development. the librarian who designed this libguide had included search widgets in separate boxes on the page that searched the catalog and the discovery layer “onesearch.” we were interested in seeing whether students would use the embedded search boxes to search for books. this functionality was identical in both the version one and two instances of the guide, as shown in figure 7. figure 7. embedded catalog search and embedded discovery layer search. task 5 in the fifth scenario, students were told that they were designing an earthquake-resistant structure for a civil engineering class. as part of that process, they were required to review am i on the library website? | conrad and stevens 60 https://doi.org/10.6017/ital.v38i3.10977 seismic load provisions. we asked them to locate the asce standards on seismic loads using a research guide we opened for them. the asce standard was located on the “codes & standards” page, which could be accessed by clicking on the “codes & standards” tab. the version one instance of the guide was two-columned, and a link to the asce seismic load standard was available in the second column on the right, per figure 8. the version two instance of the guide used a single, centered column, and the user had to scroll down the page to find the standard, per figure 9. we wanted to see if students noticed content in columns on the right, as many of our libguides featured books, articles, and other resources in columns on the right side of the page, or whether guides with content in a single central column were easier for students to use. figure 8. two-column design with horizontal tabs. information technology and libraries | september 2019 61 figure 9. two-column design with left tab navigation. task 6 because librarians sometimes included screenshots of search interfaces in their guides, we were interested in testing whether students mistook these images of search tools for actual search boxes. in task six, we opened a civil engineering libguide for students and told them to find an online handbook or reference source on the topic of finite element analysis. as shown in figure 10, a screenshot of a search box was accompanied by instructional text explaining how to find specific types of handbooks. within this libguide, there were also screenshots of the onesearch discovery layer as well as a screenshot of a “findit” link resolver button. am i on the library website? | conrad and stevens 62 https://doi.org/10.6017/ital.v38i3.10977 figure 10. screenshots used for instruction. task 7 the final task was designed to test whether it was more difficult for students to find content in a twoor three-column guide. students were instructed to do background research on motivation and classroom learning for a psychology course. they were told to find an “encyclopedic source” on this topic. within each version of the psychology libguide, there was a section called “useful books for background research.” as shown in figure 11, in the version one libguide, books useful for background research were displayed in the third column on the right side of the page. the version two libguide displayed those same books in the first column under the left navigation options. information technology and libraries | september 2019 63 figure 11. books displayed in third column. am i on the library website? | conrad and stevens 64 https://doi.org/10.6017/ital.v38i3.10977 figure 12. two-column display with books in the left column. results searching vs. browsing to find libguides understanding how students navigate and use libguides is important, but if they have difficulty finding the libguides from the library homepage, usability of the actual guides is moot. of the ten students tested, six students used the onesearch discovery layer located on the library’s homepage to search for a guide designed to help them write a paper on climate change for a com 100 class. frequently used search terms included “research guide,” “communication guides,” “climate change,” “climate change research guide,” “faculty guides,” and “com 100.” of these students, two used search as their only strategy, typing search queries into whichever search box they discovered. neither of these students were successful at locating the correct guide. the remaining four students used mixed strategies; they started by searching and resorted to browsing after the search did not deliver exact results. two of these students were eventually successful in finding the specific research guide; two were not. of the six studen ts who searched using the discovery layer, only one did not find the libguides landing page at all. in general, it seems that the task and student expectations during testing were not aligned with the way the guide was constructed. only one student went to the controversial topics guide because “climate change is a controversial topic.” one student thought the guide would be titled “climate change” and another thought there might be a subject librarian dedicated to climate change. students would search for keywords corresponding with their course and topic, but generally they did not make the leap to focus more broadly on controversial topics. only one student browsed directly to the “research guides” link on the homepage and found the guide under subject guides for “communication" on the first try. another student navigated to a information technology and libraries | september 2019 65 “services and help” page from the main website navigation and found a group of libguides that were labeled “user guides,” designed specifically for new students, faculty, staff, and visitors; however, the student did not find any other libguides relevant to the task at hand. the remaining two students navigated to pages with siloed content; one student clicked the library catalog link on the library homepage and began searching using the keywords “climate change.” the other student clicked on the “databases” link. upon arriving at the databases a-z page, the student chose a subject area (science) and searched for the phrase “faculty guides” in the databases search box. the student was unable to find the research guide because our libguides were not indexed in this search box; only database names were listed. only three out of ten students found the guide; the rest gave up. two of the successful participants employed mixed strategies that began with searching and included some browsing; the third student browsed directly to the guide without searching. testers in the libguides version one environment attempted the task an average of 3.8 times before achieving success or giving up compared to an average of 3.2 attempts per tester in version two testing. we defined an attempt as browsing or searching for a result until the student tried a different strategy or started over. for instance, if a student tried to browse to a guide and then chose to search after not finding what they were looking for, that constituted two attempts. testers in both rounds began on the same library website. one major difference between the two research guides landing pages was the search boxes; one was an internal libguides search box (version one) and one was a global onesearch box (version two). it is possible that testers in round two made fewer attempts because of the inclusion of the onesearch box. for those testing with the libguides search box in version one, three searched on the libguides landing page. from both rounds, eight of the students located the libguides landing page, regardless of whether or not they found the correct guide. the two students who did not find the correct guide did land in libguides, but they arrived at specific libguides pages that served other purposes (one found a onesearch help guide and the other landed on a new users’ guide). navigation, tabs, and layout navigation, tab options (including subtab usage), and layouts were evaluated in tasks two, three, five, and seven. as mentioned in the method section, the first group of five students who tested the interface used the version one libguides with horizontal navigation and hidden subtabs. the second round of five students used the version two libguides with left navigation and popped open subtabs. students in both rounds were able to find items in the main navigation (not including subtabs) at consistent rates, with those in the second round with left navigation completing all tasks significantly faster than the first-round testers (38 seconds faster on average across all tasks). in task two, students were asked to find public opinion polls, which they could access by clicking a “public opinion polls” link on the main navigation. in both rounds, regardless of horizontal or vertical navigation, nine of the students clicked on the tab for the polls. only one student testing on version two was unable to find the tab. students in version one testing with horizontal navigation attempted this task two times on average before successfully finding the tab; students testing on version two with vertical navigation attempted 1.4 times before finding the tab with the polls or giving up. am i on the library website? | conrad and stevens 66 https://doi.org/10.6017/ital.v38i3.10977 when asked in task three to find articles on product development, which were included on a “product development” subtab under the primary “library databases amm” tab, nine out of ten students were unable to locate the subtab. in libguides version one, this subtab was only viewable after clicking the main “library databases amm” tab. in libguides version two, this subtab was popped open and immediately visible underneath the “library databases amm” tab. a version two tester was the only student who clicked on the “product development” subtab. students attempted this task 1.8 times in version one testing compared to 1.2 times for those testing version two. it is worth noting that six of the students found product development articles by searching via other means (onesearch, databases, and other library website links); they just did not find the articles on the libguide shown. while they still successfully found resources, they did not find them on the guide we were testing. in task five, we asked students to find the asce standards on seismic loads on a specific guide. the version one guide used a two-column design while the version two guide with the same content utilized a single column for all content. while six students found the standards (three in round one and three in round two), only four of ten testers overall did so by browsing to the resource. three of the students who chose to browse were in round one and the fourth student was from round two. in version one testing with the two-column design, two students found the standards after making two attempts to browse the guide. both of these students used the libguides “search this guide” function to find the correct page for the standards using keywords “asce standards” and “asce.” the third successful student in this round used a mixed methods strategy of searching and browsing. she used the search terms “asce standards on seismic loads” and then searched for “seismic loads” twice in the same search box. she landed on the correct tab of the libguide, scrolling over the correct standard multiple times, but only found the standards after the sixth attempt. during version two testing, which included the one column design and global search box, only one student browsed to the standards on the libguide. this student scrolled up and down the main libguide page, clicked on the left navigation option for “find books,” then the left navigation option for “codes & standards” and scrolled down to find the correct item. four out of five version two testers bypassed browsing altogether, instead using the onesearch box on the page header to try to find the asce standards. two of those students found the specific asce standards that were featured on the libguide; the other two found asce standards, just not the specific item we intended for them to find. the four students who did no t find the specific standards were equally distributed across both testing groups. on average, students attempted to complete the task 3.6 times in version one testing and 1.6 times in version two testing before either finding the resource or giving up. task seven asked students to find an encyclopedic source using a three-column design in version one and a two-column design in version two. the version one guide listed encyclopedias in the right-most column of a three-column layout and the version two guide included them under the left navigation in a two-column design. only three students found the encyclopedia mentioned in task seven, two of whom completed the task using version two’s two-column display. only one student was able to locate the encyclopedia in the third column in version one testing. the seven students who were unable to find the encyclopedia all attempted to search when they were unable to find the encyclopedia by browsing. six of these seven students searched for the keywords “motivation and classroom learning” and the seventh for “motivation and learning.” those who landed in onesearch (six out of seven) received many results and were unable to find encyclopedias. one student searched within libanswers for “encyclopedia” and found britannica. information technology and libraries | september 2019 67 one student attempted to refine by facets, thinking that “encyclopedia” would be a facet similar to “book” or “article.” using search, especially onesearch, to attempt to find an encyclopedia was ultimately unsuccessful for the students. search terms students chose were far too general for them to complete the task successfully. students in version one testing attempted this task 2.4 times compared to 3.2 times for version two testers. embedded search boxes & screenshots of search boxes embedded search boxes and screenshots of search boxes were tested in tasks four and six. the header used in version one libguides was limited, defaulting to searching within the guide, and the additional options on the dropdown menu next to the search box did not include a global “onesearch.” in version two guides, a onesearch box that searched most library resources (articles, books, library webpages, and libguides) was included. during task four, which asked students who were already on a specific guide how they would go about finding additional books on product development, version one testers were much more likely to use embedded search box widgets in the guide content. three of the five students in version one testing used the search widgets on the page to either search the catalog or search onesearch. the remaining two students in that round used a header search or browsed. one of these students used the libguides “search this guide” function in libguides and searched for “producte [sic] development books.” this student did not notice the typo in the search term and subsequently navigated out of libguides to the library website via the library link on the libguides header. the user then searched the catalog for “product development” and was able to locate books. a fifth student in the version one testing round did not use embedded search box widgets or the libguides search. she browsed through two guide pages and then gave up. in version two testing, three of five students used the global onesearch box to find the product development books. the remaining two students chose to search the millennium catalog linked from a “books and articles” tab on the main website header, finding books via that route. during testing of both versions, students tried an average of 1.5 times to complete the task before achieving success or acknowledging failure. nine out of ten testers found books on the topic of product development. the one tester who did not find the books attempted to complete the task one time; she found product development articles from the prior task and said she would click on the same links (for individual article titles) to find books. in task six, half of the ten students from both rounds attempted to click on screenshots of search boxes or unlinked “findit” buttons. a screenshot of the onesearch box and a knovel search box were embedded in the test engineering guide. two users in the version one testing and one tester in version two testing attempted to click on the onesearch screenshot. one student in version two testing attempted to click on the knovel search box screenshot. one student from version one testing tried to click on a “findit” button for the link resolver. comparisons between rounds we recorded how many attempts were needed to complete tasks in each round. in round one, which tested libguides version one, students took an average of 2.74 tries to complete the tasks. in round two, which focused on libguides version two, students took two tries to complete tasks. average attempts per task are displayed in figure 13. we also timed the rounds to see how many minutes it took students to complete all of the tasks. in the first round, it took 16:07 minutes on average and in the second round 15:29 minutes. this does not appear to constitute an important am i on the library website? | conrad and stevens 68 https://doi.org/10.6017/ital.v38i3.10977 difference, but there was one tester in round two who narrated his experiences very explicitly and in great detail. his session lasted 23 minutes. if his testing is excluded, then round two had a shorter average of 13:30 minutes. despite the lower total time spent testing, task success was nearly equal between the two rounds. details on individual testing times per participant are in figure 14. in round one, testers were successful at completing the task, whether they completed it in the manner we predicted or not, for 24 tasks. round two was slightly lower with 23 successfully completed tasks. success was, however, subjective. in task three, we wanted to test whether students found a list of articles on a libguide on a certain topic. nearly all of the students (nine out of ten) found articles on the topic, but only one of them found them via the method we had anticipated. other tasks produced similar results where the students found resources that technically fulfilled the task we had asked them to complete, even though they did not test the feature of the interface we were hoping. in these cases, we called this a success, as they had fulfilled the task as written. figure 13. attempts per task for libguides v1 compared to libguides v2. information technology and libraries | september 2019 69 figure 14. total time per participant for libguides v1 compared to libguides v2. discussion there were several overarching themes that we discovered during the testing of libguides versions one and two. the first relates to nielsen’s conception of search dominance and its implications for finding guides as well as resources within guides. task one, which asked students to navigate to a relevant libguide from the library homepage, revealed that students were much more likely to search for a guide than to navigate to one by using links. although the library homepage in our study included a clearly demarcated “research guides” link, only one tester clicked on it. in contrast, six of ten of the students used search as their first and only strategy, and an additional two of ten first clicked on a link and then switched to search as their next strategy. although our initial search-focused research question and related task looked specifically at how students navigate to guides, most of the other tasks provided additional insight into how students navigate within them as well. our findings are consistent with nielsen’s observation that search functions as an “escape hatch” when users get “stuck in navigation.”42 many students we tested used mixed strategies to find content, often resorting to searching for content when they were confused, lost, or impatient. while one student explicitly stated that search is a backup for when he cannot find something via browsing, search behaviors from many other students suggested that they were “search-dominant,” preferring searching over browsing both on library website pages and from within libguides. similar to nielsen’s studies on reliance on search engine results, students were unlikely to change their search strategies even if they were not receiving helpful results. students did not engage in what xie and joo referred to as “whole site exploration,” browsing and evaluating most of the available information on a website to accomplish the assigned tasks.43 while research guides are sometimes designed to function as linear pathways that lead students through the research process or as comprehensive resources that introduce am i on the library website? | conrad and stevens 70 https://doi.org/10.6017/ital.v38i3.10977 students to a series of tools and resources, all of which could be useful in the research process, the students we tested did not approach guides in this way. rather than starting on the first tab and comprehensively exploring it tab by tab and content box by content box, students ignored most of the content on the page, searching instead to find the specific information they needed. our testers’ search behaviors were also consonant with nielsen’s observation that scoped searches are inconsistent with users’ mental models about how search should function. nielsen found that search boxes that only cover a subsection of a site are generally confusing to users and negatively impact users’ ability to find what they are looking for on a site. in our study, several students used scoped search boxes both on library website pages and within libguides to find content that the search did not index. version two testers had access to a search box on every page that aligned with their global search expectations, and they frequently used it, so much so that they their preference for search disrupted some of the usability questions we were trying to answer in our tasks. for example, users’ tendency to search instead of browse interfered with our ability to clearly discern whether it was easier for students to find content on pages with one-, two-, or three-column content designs (many students did not even attempt to find content in the columns). students’ global search expectations of search boxes also have implications on their ability to find libguides that they have been told exist or to discover the existence of libguides that might help them with their research. for example, students with search-dominant tendencies who attempt to use a library search tool that does not index libguides or the content within libguides will be unlikely to find them. while students did use search boxes embedded within libguides content areas, version two testers had access to a global search box located at the top right-hand side of every libguides page, and as a result, they were more likely to use the global search than the embedded search boxes. this behavior is consistent with nielsen’s assertion that for ease of use, search should consist of a box “at the top of the page, usually in the right-hand corner,” that is “wide enough to contain the typical query.”44 version two testers were quick to find and use the search box in the header that fit this description. although students often used search boxes, and global ones in particular, to accomplish usability testing tasks, they were sometimes impeded by screenshots of search boxes and links. several students clicked on them thinking they were live, unable to immediately distinguish that they differed from the functional embedded search boxes that some of the guides also included. as nielsen observed, “users often move fast and furiously when they’re looking for search. as we’ve seen in recent studies, they typically scan the homepage looking for ‘the little box where i can type.’”45 librarians sometimes use screenshots of search boxes in an effort to provide helpful visuals to accompany instructional content (text) focusing on how to access and use a specific resource. because many students scan the page for a search box so that they can quickly find needed information rather than carefully reading material in the content boxes, it could be argued that these screenshots inadvertently confuse students and impede usability. another way to look at this issue, however, may be that guide content can be misaligned with user expectations and contexts. a user looking to search for articles on a topic who stumbles on a guide may have no reason to do anything other than look for a search box. in contrast, a user introduced to a guide in the context of a course who is asked to read through the content and explore three listed resources in preparation for a discussion to occur in the next class meeting will likely have a very different orientation to the guide and perception of its purpose and usefulness. information technology and libraries | september 2019 71 students’ search behaviors also made us question the efficacy of linking to specific books or articles within a libguide. in tasks three through seven, many of the students used onesearch or the library catalog to search for specific books or articles rather than referencing the guide where potentially useful resources were listed. for example, while trying to find the com 100 guide during task one, one student commented, “i never really look for stuff. i just go to the databases.” version two testers, who had access to a global search in the header of every libguides page, were even more likely to navigate away from the guides to find books or articles. while several studies in the literature had suggested that vertical tab navigation may be more usable than horizontal tab navigation, our study did not bear this out, as students in both rounds were able to find items on vertical and horizontal navigation menus at relatively consistent rates. similarly, one-, two-, and three-column content design did not appear to affect users’ abilities to find information and links on a page; however, users’ tendency to search rather than bro wse interfered with the relevant task’s intention of comparing the browsability of different content column designs, and therefore more targeted research on this question is needed. one student commented on the pointlessness of content in second columns, stating “nobody ever looks on the right side, i always look on the left cause everything’s usually on the left side. because you don’t read from right to left, it’s left to right.” he was, nevertheless, able to complete the task regardless of the multi-column design. subtab placement in libguides versions one and two was very different from each other; version one subtabs were invisible to users unless they hovered over the main menu item on the horizontal menu, while version two allowed us to make subtabs immediately visible on the vertical menu, without any action needed by the user to uncover their existence. given the subtabs’ visibility, we had anticipated that version two testers would be more likely to find and use subtabs, but this turned out not to be the case. only one out of ten students found the relevant subtab. although the successful tester was using libguides version two in which the subtab was visible, the fact that nine out of ten testers failed to see the subtab, regardless of whether it was immediately visible or not, suggests that subtab usage may not be an effective navigation strategy. results from all tasks also suggested that students might not understand what research guides are or how guides might help them with their research. like many libraries, the cal poly pomona university library did not refer to libguides by their product name on the library website, labeling them “research guides” instead in an effort to make their intended purpose clearer. testing revealed, however, that students are not predisposed to think of a “research guide” as a useful tool to help them get started on their research. one student said, “i’m not sure what the definition of a research guide is.” when prompted to think more about what it might be, the student guessed that it was a pamphlet with “something to help me guide the research.” the student did not offer any additional guesses about what specifically that help might look like. moreover, students’ tendency to resort to search itself can also be interpreted as evidence that they are confused about how guides are supposed to help them with research. instead of reading or skimming information on the guides, students used search as a strategy to attempt to complete the tasks an average of 70 percent of the time across both rounds. many of their searches navigated students away from the very guides that were designed to help them. the tendency to navigate away from guides was likely increased by the content included in the guides we tested, since many incorporated search boxes and links that pointed to external systems, such as the catalog, the discovery layer, libanswers, etc. however, many students’ first attempts to am i on the library website? | conrad and stevens 72 https://doi.org/10.6017/ital.v38i3.10977 accomplish the tasks given them involved immediately navigating away from libguides. others navigated away shortly after an initial attempt or two to complete the task within the guide. all but one student navigated away from libguides to complete tasks; four did so more than five times. eight of ten students used onesearch in the header or from the library homepage; the other two used embedded onesearch boxes on the libguides. results also suggested that it might be easier for students to find guides that are explicitly associated with their courses, through either the guides’ titles or other searchable metadata, than to find and understand the relevance of general research guides. even though general research guides might be relevant to the subject matter of students’ courses, guides that explicitly reference a course or courses are easily discoverable and their relevance is more immediately obvious. for instance, the first task asked students to find a “research guide” to help them write a paper on climate change for a com 100 class. we wanted to see whether students would find the “controversial topics” research guide that was designed for com 100 and that included the course number in the guide’s metadata. mentioning the course number in the task seemed to make it more actionable as an assignment they might expect from a professor. when students searched for “com 100,” they were more likely to find the controversial topics guide; two of three students who found the guide searched using the course number. if course numbers had not been included, they might not have found the guide as searching for the course number brought up the correct guide as the one result. two additional students unsuccessfully attempted to find the guide by searching for “com100,” without a space. had the libguides search been more effective, or had librarians included both versions of the course code with and without a space, more students would likely have found the guide. limitations limitations of this study include weaknesses in both our usability tasks and the content of some of the libguides, which made it difficult to answer our research questions. we may have tested too many different features at once, which can be a pitfall of usability testing in general. some tasks, such as tasks five and seven, tested both navigation placement and column layouts. in task five, for instance, there were multiple factors that could have led to success or failure; did a student overlook the asce standards because of column layout or tab placement or was the layout moot because the search box was comprehensive enough to allow them to complete the task without browsing the guide’s content? similarly, task two tested a guide with seven tabs. it is not clear if the students who did not click on a tab missed it because of the placement of the navigation on the page or because the navigation contained too many options. weaknesses in the content of many of the libguides used in the study led to additional limitations. many of the libguides were text heavy and included jargon. one student even commented, “ it’s a lot of words here, so i really don’t want to read them.” although we set out to test the usability of different navigation layouts and template designs, factors such as content overload or use of jargon could have influenced success or failure. the wording of task seven, for example, was particularly problematic and led to unclear results. students were instructed to find an “encyclopedic source” in an attempt to see if they would click on books listed in a third column in version one testing compared to a left column in version two testing. the column header was titled “useful books for background research” and the box included encyclopedias. students appeared to struggle with the idea of what constituted an “encyclopedic source.” when one student was specifically asked what she thought the term meant, she responded, “not sure.” based information technology and libraries | september 2019 73 on the results of this task, it was difficult to discern if the interface or the wording of the task resulted in task completion failures. the contrived nature of usability testing itself might also have affected our results. for example, one student exhibited a tendency to rush through tasks, a behavior that may have been due to experiencing content overload, anxiety over being observed during the testing process, time limitations of which we were unaware, etc. on the other hand, behavior that we perceived to be rushing might be consistent with the students’ normal approach to navigating websites. whatever the case, it is important to keep in mind that usability testing puts users on the spot because they are testing an interface in front of an audience. the usability testing context can therefore influence user behavior, including the number of times students might attempt to find a resource or complete a given task. some students might be impatient or uncomfortable with the process, resulting in attempts to complete the testing as quickly as possible, including giving up on tasks more quickly than they would in a more natural setting. conversely, other students might be more likely to expend more time and effort when performing in front of an audience than they would privately. conclusion usability testing was effective for revealing some of the difficulties students encounter when using our libguides and our website and for prompting reflection on the types of content they include, how that content is presented, and the contexts in which that content may or may not be useful to our students. analysis of the data from our study and a review of the literature within the context of existing political realities and constraints within our library led to our development of several data-informed recommendations for libguides creators, most of which were adopted. one of the most important recommendations was that libguides should use the same header that is on the library’s main website, which includes a global search box. use of the similar header not only would provide a consistent look and feel but it would also provide users with the global search box at the top of the page that is aligned with their mental model of how search should function. our testing confirmed many students prefer to use global search boxes to find information rather than browsing or in addition to browsing when they get stuck. while some librarians were not thrilled with what they viewed as the privileging or predominance of the discovery layer on their guides, preferring to direct students to specific databases instead of the onesearch, this recommendation was ultimately accepted due to the compelling nature of the usability data we were able to share. our recommendation that subtabs should be avoided was also accepted because of how compelling the data was: 90 percent of users failed to find links located on subtabs. we also recommended that librarians should evaluate the importance of all content on their guides to minimize student confusion when browsing. while we acknowledged that there might be contexts when screenshots of search boxes would be useful, we encouraged librarians to think carefully about their use and to avoid them when possible. additionally, librarians were encouraged to evaluate whether the content they were adding was of core importance to the libguide, reflecting on the degree to which it added value or possibly detracted from the libguide, perhaps by virtue of lack of relevance or content-overload. content boxes consisting of suggested books on a general subject guide were used as an example, given the difficulty of providing useful book suggestions to students working on wildly different topics. while results from our rounds of usability testing did not indicate that left-side vertical navigation was decidedly more usable than horizontal navigation at the top of the page, we nevertheless am i on the library website? | conrad and stevens 74 https://doi.org/10.6017/ital.v38i3.10977 recommended that all guides should use left tab navigation, for consistency’s sake across guides, because left-side navigation has become standard on the web, and because other libguide studies have suggested that left-side navigation is easier to use than horizontal navigation, due to issues such as “banner blindness.”46 the librarians agreed, and a template was set up in the administrative console requiring that all public-facing libguides use left tab navigation. based on other usability studies in the literature as well, we also recommended that guides should include no more than a maximum of seven main content tabs.47 although our study did not provide any actionable data about the relative usability of one-, two-, and three-column content designs, other articles in the literature had emphasized the importance of consistency and avoiding a busy look with too much content. in order to avoid both a busy look and having guides that looked decidedly different from each other due to inconsistent number of columns, we therefore recommended that all guides should utilize a two-column layout, with the left column reserved for navigation. all content should appear in a single main column. however, future iterations of libguides usability testing should attempt to find ways to test whether limiting content to a single column is indeed more usable than dispersing it across two or more columns. the group voted on many of our recommendations, and several were simple to implement and oversee because they could translate into design decisions that could be set up as default, unchangeable options within the libguides administration module. other recommendations were more difficult to operationalize and enforce. for example, because our findings indicated that students attempted to search for course numbers to find a guide that they were told was relevant to their research for a specific class, another one of our recommendations to the librarians’ group was to include, as appropriate, various course numbers in their guides’ metadata in order to both make them more discoverable and appear more immediately relevant to students’ coursework. this recommendation is not one that a libguides administrator could enforce due to issues revolving around subject matter and curriculum knowledge. the issue of context, and specifically the connection between courses and guides that has the potential to underscore their relevance and purpose to students, also caused us to question the effectiveness of general subject guides in assisting students with their research. if students are more likely to understand the relevance and purpose of a libguide when it is explicitly connected to their specific class or assignment and less likely to make the connection between a general research guide and their coursework, then the creation and maintenance of general subject guides might not be worth the time and effort librarians invest in them. this question is made more pressing by studies in the literature that indicate both low usage and shallow use of guides, such as using them primarily to find a database.48 while this question did not lead to a specific recommendation to the librarians’ group, we have since reflected that the return on investment issue might be effectively addressed via closer collaboration with faculty in the disciplines. if research guides are more clearly aligned with specific research assignments in specific courses , and if faculty members instruct their students to consult library research guides and integrate libguides and other library resources into learning management systems, perhaps use and return on investment would improve. researchers like hess and hristova, for example, found that online tutorials that are required in specific courses show high usage.49 the connection between course integration and usage may hold true with libguides as well. regardless, students’ frequent lack of understanding of what guides are designed to do and their tendency to navigate quickly away from them rather than exploring them suggests that information technology and libraries | september 2019 75 reconceptualizing what guides are designed to do, and what needs they are designed to meet in what specific contexts might prove to be a useful exercise. a guide designed as an ins tructional tool to teach specific concepts, topic generation processes, search strategies, citation practices, etc. within the context of a specific assignment for a specific course may well be immediately perceived as relevant to students in that course. such a guide discussed in the context of a class might also be perceived as more useful than guides consisting of lists of resources and tools, which are unlikely to be interpreted as helpful by students who stumble upon them while seeking research assistance on the library’s website. as such, thinking about how and in what context students are likely to find guides, and how material might be presented so that guides are quickly perceived as a potentially relevant resource worth exploring might also prove useful. the importance of talking to users cannot be overemphasized; without collecting user feedback, whether through usability testing or another method, it is difficult to know how students perceive and use libguides or any other library online service. getting user input on navigation flow, template design, and search functionality can provide valuable details that can help libraries improve the usability of their online resources. it is also important to note that in our rapidly changing environment, users’ needs and preferences also change. as such, collecting and analyzing user feedback to inform user-centered design should be a fluid process, not a one-time effort. admittedly, it can sometimes be challenging to make collective design decisions, particularly when librarians have strong opinions grounded on their own personal experiences working with students that conflict with usability testing data. although it is necessary to incorporate user feedback into the design process, it is also important to be open to compromise in order to achieve stakeholder buy-in for some usability-informed changes. as with many library services, usage of libguides is contingent at least in part on awareness, as students are unlikely to use services of which they are unaware or are unlikely to discover due to the limitations of a library’s search tools. given the prevalence of search dominance among our users, we should not assume that simply placing a “research guides” link on a webpage will lead to usage. increased outreach, better integration with the content of specific courses and assignments, and a thorough review of libguides content by those creating the guides with an eye toward the specific contexts in which they are likely to be used, taught, serendipitously discovered, etc. is necessary to ensure that the research guides librarians create are worth the time they invest in them. additional studies focusing on why students do or do not use specific types of research guides, the contexts in which they are most useful, how students use them, and the specific content in guides that students find most helpful are needed to determine whether and to what extent they are aligned with students’ information-seeking preferences, behaviors, and needs, as well as how they might be improved to increase their use and usefulness. am i on the library website? | conrad and stevens 76 https://doi.org/10.6017/ital.v38i3.10977 appendix 1: libguides usability testing

imagination and structure in times of change bohyun kim information technology and libraries | december 2018 2 bohyun kim (bohyun.kim.ois@gmail.com) is lita president 2018-19 and chief technology officer & associate professor, university of rhode island libraries, kingston, ri. in my last column, i talked about the discussion that lita had begun regarding forming a new division to achieve financial sustainability and more transparency, responsiveness, and agility. this proposed new division would merge lita with alcts (association for library collections and technical services) and llama (library leadership and management association). when this topic was brought up and discussed at an open meeting at the 2018 ala annual conference in new orleans, many members of these three divisions expressed interests and excitement. at the same time, there were many requests for more concrete details. you may recall that as a response to those requests, the steering committee, which consists of the presidents, presidents-elect, and executive directors of the three divisions decided to form four working groups with the aim of providing more complete information about what the new division would look like. today, i am happy to report that the work of the steering committee and the four working groups is well underway. the operations working group that i have been chairing for the last two months submitted its recommendations on november 23. the activities working group finished its report on december 5. the budget and finance working group also submitted its second report. the communications working group continues to engage members of all three divisions by sharing new updates and soliciting opinions and suggestions. most recently, it started gathering input and feedback on potential names for the new division.1 you can see the charges, member rosters, and current statuses of these four working groups in the ‘current information’ page at the ‘alcts/ llama/ lita alignment discussion’ community in the ala connect website (https://connect.ala.org/communities/allcommunities/all/all-current-information).2 to give you a glimpse of our work preparing for the proposed new division, i would like to share some of my experience leading the operations working group. the operations working group consisted of nine members, three from each division, in addition to myself as the chair and one staff liaison. we quickly became familiar with the organizational and membership structures of three divisions. the three divisions are similar to one another in size, but they have slightly different structures. lita has 18 interest groups (ig), 25 committees, and 4 (current) task forces; llama has 7 communities of practice (cop) and 46 discussion groups / committees / task forces; alcts has 5 sections, 42 igs, and 61 committees (20 at the division level and 41 at the section level). all committees and task forces in lita are division-level, while alcts and llama have committees that are either division-level or section/cop-level. alcts is unique in that it elects section chairs, who serve on the division board alongside with alcts directors-at-large. alcts also has a separate executive committee in addition to the board. llama has self-governed cops, which are formed by the board’s approval. among all three, lita has the most flat and simplest structure due to its intentional efforts in the past. for example, there are neither sections nor mailto:bohyun.kim.ois@gmail.com https://connect.ala.org/communities/allcommunities/all/all-current-information information technology and libraries | december 2018 3 communities of practice in lita, and the lita board eliminated the executive committee a few years ago. the steering committee of the three divisions agreed upon several guiding principles for the potential merger. these include (i) open, flexible, and straightforward member engagement, (ii) simplified and streamlined processes, and (iii) a governance and coordinating structure that engages members and staff in meaningful and productive work. the challenge is how to translate those guiding principles into a specific organizational structure, membership structure, and bylaws. clearly, some shuffling of existing sections, cops, and igs in three divisions will be necessary to make the new division as effective, agile, and responsive as promised. however, when and how such consolidation should take place? furthermore, what kind of guidance should the new division provide for members to re-organize themselves into a new and better structure? these are not easy questions to answer. nor are they something that can be immediately answered. some changes may require going through multiple stages for them to be completed. this may concern some members. they may prefer all these questions to have definitive answers before they decide on whether they will support the proposed new division or not. people often assume that a change takes place after a big vision is formed, and then the change is executed by a clear plan that directly translates that vision into reality in an orderly fashion. however, that is rarely how a change takes place in reality. more often than not, a possible change builds up its own pressure, showing up in a variety of forms on multiple fronts by many different people while getting stronger, until the idea of this change gains enough urgency. finally, some vision of the change is crafted to give a form to that idea. the vision for a change also does not materialize in one fell swoop. it often begins with incomplete details and ideas that may even conflict with one another in its first iteration. it is up to all of us to sort them out and make them consistent, so that they would become operational in the real world. recently, the steering committee reached an agreement regarding the final version of the mission, vision, and values of the proposed new division. i hope these resonate with our members and guide us well in navigating challenges ahead if the membership votes in favor of the proposal. the new division’s mission: we connect library and information practitioners in all career stages and from all organization types with expertise, colleagues, and professional development to empower transformation in technology, collections, and leadership, and to advocate for access to information for all. the new division’s vision: we shape the future of libraries and catalyze innovation across boundaries. the new division [name to be determined] amplifies diverse voices and advocates for equal and equitable access to information for all. the new division’s values: shared and celebrated expertise; strategically chosen work that makes a difference; transparent, equitable, flexible, and inclusive structures; empowering framework for experimental and proven approaches; intentional amplification of diverse perspectives; expansive collaboration to become better together. imagination and structure in times of change | kim 4 https://doi.org/10.6017/ital.v37i4.10850 in deciding on all operational and logistical details for the new division, the most important criteria will be whether a proposed change will advance the vision and mission of the new division and how well it aligns with the agreed-upon values and guiding principles. the steering committee and the working groups are busy finalizing the details about the new division. those details will be first reviewed by the board of each division and then shared with the membership at the midwinter for feedback. i did not anticipate that during my service as the lita president-elect and president, i would be leading a change as great as dissolving lita and forming a new division with two other divisions, alcts and llama. it has been an adventure filled with many surprises, difficulties, and challenges, to say the least. this adventure taught me a great deal about leading a change for an organization at a high level. when we move from the high-level vision of a change to the matter of details deep in the weeds, it is easy to lose sight of the original aspiration and goal that led us to the change in the first place. trying to determine as many logistical details becomes tempting to those in a leadership role because we all want to assure people in our organizations at a time of uncertainty and to make the transition smooth. however, creating a new division itself is a huge change at the highest level. it would be wrong to backtrack on the original goal to make the transition smooth. for it is the original goal that requires a transition, not vice versa. i believe those in a leadership role should accept that their most important work during the time of change is not to try to wrangle logistics at all levels but to keep things on track and moving in the direction of the original aspiration and goal. lita and two other divisions have many talented and capable members who will be happy to lend a hand in developing new logistics. the responsibility of leaders is to create space where those people can achieve that freely and swiftly and to provide the right amount of framework and guidance. i hope that all lita members and those associated and involved with lita see themselves in the vision, mission, and values of the new division, embrace changes from the lowest to the highest level, and work towards making the new vision into reality together. 1 you can

singularity—are we there, yet? | truitt 55 i n my last column, i wrote about two books—nicholas carr ’s the shallows and william powers’ hamlet’s blackberry—relating to learning in the always-on, always connected environment of “screens.”1 since then, two additional works have come to my attention. while i won’t be able to do them justice in the space i have here, they deserve careful consideration and open discussion by those of us in the library community. if carr’s and power’s books are about how we learn in an always-connected world of screens, sherry turkle’s alone together and elias aboujaoude’s virtually you are about who we are in the process of becoming in that world.2 turkle is a psychologist at mit who studies human– computer interactions. among her previous works are the second self (1984) and life on the screen (1995). aboujaoude is a psychiatrist at the stanford university school of medicine, where he serves as director of the obsessive compulsive disorder clinic and the impulse control disorders clinic. based on extensive coverage of specialist and popular literature, as well as numerous anonymized accounts of patients and subjects encountered by the authors, both works are characterized by thorough research and thoughtful analysis. while their approaches to the topic of “what we are becoming” as a result of screens may differ— aboujaoude’s, for example, focuses on “templates” and the terminology of traditional psychiatry, while turkle’s examines the relationship between loneliness and solitude (they are different), and how these in turn relate to the world of screens—their observations of the everyday manifestations of what might be called the pathology of screens bear many common threads. i’m acutely aware of the potential for injustice (at best) and misrepresentation or misunderstanding (rather worse) that i risk in seeking to distill two very complex studies into such a small space. and, frankly, i’m still trying to wrap my head around both the books and the larger issues they raise. with that caveat, i still think we should be reading about and widely discussing the phenomena reported, which many of us observe on a daily basis. in the sections that follow, i’d like to touch on a very few themes that emerge from these books. ■■ “why do people no longer suffice?”3 a pair of anecdotes that turkle recounts to explain her reasons for writing the current book seems worth sharing at the outset. in the first, she describes taking her then-fourteen-year-old daughter, rebecca, to the charles darwin exhibition at new york’s american museum of natural history in 2005. among the many artifacts on display was a pair of live giant galapagos tortoises: “one tortoise was hidden from view; the other rested in its cage, utterly still. rebecca inspected the visible tortoise thoughtfully for a while and then said matter-of-factly, ‘they could have used a robot.’” when turkle queried other bystanders, many of the children agreed, with one saying, ‘for what the turtles do, you didn’t have to have live ones.’” in this case, “alive enough” was sufficient for the purpose at hand.4 sometime later, turkle read and publicly expressed her reservations about british computer scientist david levy’s book, love and sex with robots, in which levy predicted that by the middle of this century, love with robots will be as normal as love with other humans, while the number of sexual acts and lovemaking positions commonly practiced between humans will be extended, as robots will teach more than is in all of the world’s published sex manuals combined.5 contacted by a reporter from scientific american about her comments regarding levy’s book, turkle was stunned when the reporter, equating the possibility of relationships between humans and robots with gay and lesbian relationships, accused her of likewise opposing these human-to-human relationships. if we now have reached a point where gay and lesbian relationships can strike us as comparable to human-to-machine relationships, something very important has changed; for turkle, it suggested that we are on the threshold of what she terms the “robotic moment”: this does not mean that companionate robots are common among us; it refers to our state of emotional—and i would say philosophical—readiness. i find people willing to seriously consider robots not only as pets but as potential friends, confidants and romantic partners. we don’t seem to care what these artificial intelligences “know” or “understand” of the human moments we might “share” with them. at the robotic moment, the performance of connection seems connection enough. we are poised to attach to the inanimate without prejudice.6 marc truitteditorial: singularity—are we there, yet? marc truitt (marc.truitt@ualberta.ca) is associate university librarian, bibliographic and information technology services, university of alberta libraries, edmonton, alberta, canada, and editor of ital. 56 information technology and libraries | june 2011 while these examples are admittedly extreme, both authors agree that something very basic has changed in the way we conduct ourselves. turkle characterizes it as mobile technology having made each of us “pausable,” i.e., that a face-to-face interaction being interrupted by an incoming call, text message, or e-mail is no longer extraordinary; rather, in the “new etiquette,” it is “close to the norm.”10 and the rudeness, as well we know, isn’t limited to mobile communications. referring to “flame wars,” which regularly erupt in online communities, aboujaoude observes: the internet makes it easier to suspend ethical codes governing conduct and behavior. gentleness, common courtesy, and the little niceties that announce us as well-mannered, civilized, and sociable members of the species are quickly stripped away to reveal a completely naked, often unpleasant human being.11 even our routine e-mail messages—lacking as they often do salutations and closing sign-offs—are characterized by a form of curtness heretofore unacceptable in paper communications. remarkably, to those old enough to recall the traditional norms, the brusqueness is not only unintended, it is as well unconscious; “[we] just don’t think warmth and manners are necessary or even advisable in cyberspace.”12 ■■ castles in the air: avatars, profiles, and remaking ourselves as we wish we were finally, a place to love your body, love your friends, and love your life. —second life, “what is second life?”13 one of the interesting and worrisome themes in both turkle’s and aboujaoude’s studies is that of the reinvention and transformation of the self, in the form of online personas and avatars. this is the stock-in-trade of online communities and gaming sites such as facebook and second life. these sites cater to our nearly universal desire to be someone other than who we are: online, you’re slim, rich, and buffed up, and you feel you have more opportunities than in the real world. . . . we can reinvent ourselves as comely avatars. we can write the facebook profile that pleases us. we can edit our messages until they project the self we want to be.14 the problem is that for many there is an increasing fuzziness at the interface between real and virtual ■■ changing mores, or the triumph of rudeness i can’t think of any successful online community where the nice, quiet, reasonable voices defeat the loud, angry ones. . . . the computer somehow nullifies the social contract. —heather champ, yahoo!’s flickr community manager7 sadly, we’ve all experienced it. we get stuck on a bus, train, or in an elevator with someone engaged in a loud conversation on her or his mobile phone. all too often, the person is loudly carrying on about matters we wish we weren’t there to hear. perhaps it’s a fight with a partner. or a discussion of some delicate health matter. whatever it is, we really don’t want to know, but because of the limitations imposed by physical spaces, we can’t avoid being a party to at least half of the conversation. what’s wrong with these individuals? do they really have no consideration or sense of propriety? it turns out that in matters of tact and good taste, the ground has shifted, and where once we understood and abided by commonly accepted rules of conduct and respect for others, we do so no longer. indeed, the everyday obnoxious intrusions by those using public spaces for their private conversations are among the least of offenders. consider the following situations shared by turkle: sal, 62 years old, holds a small dinner party at his home as part of his “reentry into society” after several years of having cared for his recently deceased wife: i invited a woman, about fifty, who works in washington. in the middle of a conversation about the middle east, she takes out her blackberry. she wasn’t speaking on it. i wondered if she was checking her e-mail. i thought she was being rude, so i asked her what she was doing. she said that she was blogging the conversation. she was blogging the conversation.8 turkle later tells of attending a memorial service for a friend. several [attendees] around me used the [printed] program’s stiff, protective wings to hide their cell phones as they sent text messages during the service. one of the texting mourners, a woman in her late sixties, came over to chat with me after the service. matter-of-factly, she offered, “i couldn’t stand to sit that long without getting on my phone.” the point of the service was to take a moment. this woman had been schooled by a technology she’d had for less than a decade to find this close to impossible.9 editorial: singularity—are we there, yet? | truitt 57 enough” became yet more blurred. turkle’s anecdotes of children explaining the “aliveness” of these robots are both touching and disturbing. speaking of a tamagotchi, one child wrote a poem: “my baby died in his sleep. i will forever weep. then his batteries went dead. now he lives in my head.”19 the concept of “alive enough” is not unique to the very young, either. by 2009, sociable robots had moved beyond children’s toys with the introduction of paro, a baby seal-like “creature” aimed at providing companionship to the elderly and touted as “the most therapeutic robot in the world. . . . the children were onto something: the elderly are taken with the robots. most are accepting and there are times when some seem to prefer a robot with simple demands to a person with more complicated ones.”20 where does it end? turkle goes on to describe nursebot, a device aimed at hospitals and long-term care facilities, which colleagues characterized as “a robot even sherry can love.” but when turkle injured herself in a fall a few months later, [i was] wheeled from one test to another on a hospital stretcher. my companions in this journey were a changing collection of male orderlies. they knew how much it hurt when they had to lift me off the gurney and onto the radiology table. they were solicitous and funny. . . . the orderly who took me to the discharge station . . . gave me a high five. the nursebot might have been capable of the logistics, but i was glad that i was there with people. . . . between human beings, simple things reach you. when it comes to care, there may be no pedestrian jobs.21 but need we librarians care about something as farfetched as nursebot? absolutely. now that ibm has proven that it can design a machine—okay, an array of machines, but something much more compact is surely coming soon—that can win at jeopardy!, is the robotic reference librarian really that much of a hurdle? take a bit of watson technology, stick it in nursebot, give it sensible shoes, and hey, i can easily imagine bibliobot, factory-standard in several guises, including perhaps donna reed (as mary, who becomes the town librarian in the alter-life of capra’s it’s a wonderful life) or shirley jones (as marian, the librarian, in the music man). i like donna reed as much as anyone, but do i really want reference assistance from her android doppelgänger? but then, for years after the introduction of the atm, i confess that i continued taking lunch hours off just so that i could deal with a “real person” at the bank, so perhaps it’s just me. the future is in the helping/service professions, indeed! and when we’re all replaced by robots (sociable and otherwise), what will we do to fill the time? personas: “not surprisingly, people report feeling let down when they move from the virtual to the real world. it is not uncommon to see people fidget with their smartphones, looking for virtual places where they might once again be more.”15 turkle speaks of the development of what she terms a “vexed relationship” between the real and the virtual: in games where we expect to play an avatar, we end up being ourselves in the most revealing ways; on social-networking sites such as facebook, we think we will be presenting ourselves, but our profile ends up as somebody else—often the fantasy of who we want to be. distinctions blur.16 and indeed, some completely lose sight of what is real and what is not. aboujaoude relates the story of alex, whose involvement in an online community became so consuming that he not only created for himself an online persona—“’i then meticulously painted in his hair, streak by streak, and picked “azure blue” for his eye color and “snow white” for his teeth.’”—but also left his “real” girlfriend after similarly remaking the avatar of his online girlfriend, nadia—“from her waist size to the number of freckles on her cheeks.” speaking of his former “real” girlfriend, alex said, “real had become overrated.”17 ■■ “don’t we have people for these jobs?”18 ageist disclaimer: when i grew up, robots—those that weren’t in science fiction stories or films—were things that were touted as making auto assembly lines more efficient, or putting auto workers out of jobs, depending on your perspective. while not technically a robot, the other machine that characterized “that time” was the automated teller machine (atm), which freed us from having to do our banking during traditional weekday hours, and not coincidentally resulted, again, in the loss of many entry-level jobs in financial institutions. as i recall, we were all reassured that the future lay in “helping/ service” professions, where the danger of replacement by machines was thought to be minimal. now, fast forward 30 years. the first half of turkle’s book is the history of “sociable robots” and our interactions with them. moving from the reactions of mit students to joseph weizenbaum’s eliza in the mid-1970s, she recounts her studies of children’s interactions, first with electronic toys—e.g., tamagotchi—and later, with increasingly sophisticated and “alive” robots, such as furby, aibo, and my real baby. with each generation, these devices made yet more “demands” on their owners—for care, “feeding”, etc. and with each generation, the line between “alive” and “alive 58 information technology and libraries | june 2011 to admit that we’ve seen many examples of how connectedness between people we’d otherwise consider “normal” has and is changing our manners and mores.24 many libraries and other public spaces, reacting to patron complaints about the lack of consideration shown by some users, have had to declare certain areas “cell phone free.” in the interest of getting your attention, i’ve admittedly selected some fairly extreme examples from the two books at hand. however, i think the point is that, now that the glitter of always-on, always-connected, has begun to fade a bit, there is a continuum of dysfunctional behaviors that we are beginning to notice, and it’s time to talk about how we as librarians fit into all of this. are there things we in libraries are doing that encourage some of these less desirable and even unhealthy behaviors? which takes us to a second concern raised by some of my gentle draft-readers: we’ve heard this tale before. television, and radio before it, were technologies that, when they were new, were criticized as corrupting and leading us to all sorts of negative, self-destructive, and socially undesirable behaviors. how are screens and the technology of always-connected any different? a part of me—the one that winces every time someone glibly refers to the “transformational” changes taking place around us—agrees. i was trained as a historian, to take a long view about change. and we’re talking about technologies that—in the case of the web— have been in common use for just over fifteen years. that said, my interest here is in seeing our profession begin a conversation about how connective technologies have influenced behavioral changes in people, and especially about how we in libraries may be unwittingly abetting those behavioral changes. television and radio were fundamentally different technologies in that they were one-way broadcast tools. and to the best of my recollection, neither has ever been widely adopted by or in libraries. yes, we’ve circulated videos and sound recordings, and even provided limited facilities for the playback of such media. but neither has ever really had an impact on the traditional core business of libraries, which is the encouragement and facilitation of the largely solitary, contemplative act of reading. connective technologies, in the form of intelligent machines and network-based communities, can be said to be antithetical to this core activity. we need to think about that, and to consider carefully the behaviors we may be encouraging. notwithstanding those critics of change in our profession who feel we move far too glacially, i would maintain that we have often been, if not at the forefront of the technology pack, then certainly among its most enthusiastic ■■ where from here? i titled this column “singularity.” for those not familiar with the literature of science fiction, turkle provides a useful explanation: this notion has migrated from science fiction to engineering. the singularity is the moment—it is mythic; you have to believe in it—when machine intelligence crosses a tipping point. past this point, say those who believe, artificial intelligence will go beyond anything we can currently conceive. . . . at the singularity, everything will become technically possible, including robots that love. indeed, at the singularity, we may merge with the robotic and achieve immortality. the singularity is technological rapture.22 i think it’s pretty clear that we’re still a fair distance from anything that one might reasonably term a singularity. but the concept is surely present, albeit in a somewhat less hubristic degree, when we speak in uncritical awe of “game-changing” or “transformational” technologies. turkle puts it this way: the triumphalist narrative of the web is the reassuring story that people want to hear and that technologists want to tell. but the heroic story is not the whole story. in virtual worlds and computer games, people are flattened into personae. on social networks, people are reduced to their profiles. on our mobile devices, we often talk to each other on the move and with little disposable time—so little, in fact, that we communicate in a new language of abbreviation in which letters stand for words and emoticons for feelings. . . . we are increasingly connected to each other but oddly more alone: in intimacy, new solitudes.23 some of my endlessly patient friends—the ones who provide both you and me with some measure of buffering from the worst of my rants in prepublication drafts of these columns—have asked questions about how all this relates to libraries, for example: how much it is legitimate to generalize to the broader population research findings from cases of obsessive compulsive disorder? the individuals studied are, of course, obsessive and compulsive, in relation to the internet and new technologies. do their behaviors not represent an extreme end of the population? a fair question. and yes, the examples i’ve provided in this column are admittedly somewhat extreme. but turkle and aboujaoud both point to many examples that are far more common. i think all of us would have editorial: singularity—are we there, yet? | truitt 59 references and notes 1. marc truitt, “editorial: the air is full of people,” information technology and

little reservation just about every technology trend that’s come along in the past few decades. at the same time, we’ve been remarkably uncritical and unreflective about our role in, and the larger implications of, what we might be doing by adopting these technologies. aboujaoude, in a surprising, but i think largely correct summary comment, observes: extremely little is available, however, for the individual interested in learning more about how virtual technology has reshaped our inner universe and may be remapping our brains. as centers of learning, public libraries, schools, and universities may be disproportionately responsible for this deficiency. they outdo one another in digitalizing their holdings and speeding up their internet connections, and rightfully see those upgrades as essential to compete for students, scholars, and patrons. in exchange, however, and with few exceptions, they teach little about the unintended, less obvious, and more personal consequences of the world wide web. the irony is, at least in some libraries’ case, that their very survival seems threatened by a shift that they do not seem fully engaged in trying to understand, much less educate their audiences about.25 i could hardly agree more. so, how do we answer aboujaoude’s critique? 4 information technology and libraries | march 2007 this study examines how social scientists arrive at and utilize information in the course of their research. results are drawn about the use of information resources and channels to address information inquiry, the strategies for information seeking, and the difficulties encountered in information seeking for academic research in today’s information environment. these findings refine the understanding of the dynamic relationship between information systems and services and their users within social-scientific research practice and provide implications for scholarly information-system development. t he information needs and information­seeking behavior of social scientists have been the focus of inquiry within library and information science (lis) research for decades. folster reviewed the major studies that have been conducted in this area over the past three decades.1 she found that research methods had developed through several stages. research prior to the 1960s usually consisted of questionnaire­based user studies that gathered basic demographic data and quan­ titative data on the type of information used. following that were citation studies in the mid­1960s, and then the combination of questionnaire and interview techniques to develop profiles of users and their needs in the 1970s. the information environment of the 1980s witnessed a major transition in research design. the former practice of studying large groups via questionnaires or struc­ tured interviews gave way to the use of unstructured interviews or observation of smaller groups, resulting in a more holistic picture of social scientists’ research practices. more fully developed techniques for behavioral models emerged in the 1990s. folster summarized these studies done over decades and concluded that (1) social scientists place a high importance on journals; (2) most of their citation identification comes from journals; (3) infor­ mal channels, such as consulting colleagues and attend­ ing conferences, are an important source of information; (4) library resources, such as catalogs, indexes, and librar­ ians, are not very heavily utilized; and (5) computerized services are ranked very low in their importance to the research process. there are many examples of studies about the infor­ mation­seeking behavior of social scientists. for example, the infross project (investigation into information requirements of the social scientist) studied the informa­ tion needs of british social scientists in the late 1960s and early 1970s and found that they preferred to use journal citations instead of traditional bibliographic tools, and that they tended to consult with colleagues and subject experts, rather than library catalogs or librarians in order to locate information.2 other social­scientist studies reinforced the findings of the infross project.3 several studies indicated that computerized literature searching was ranked low as a source of information among social scientists and suggested the promotion of electronic information services by librarians to enhance their roles as information providers.4 in an influential study on social scientists’ informa­ tion­seeking patterns, ellis developed a behavioral model with six features based on the stages they went through in gathering information: ■ starting—includes activities characteristic of the ini­ tial search for information, such as asking colleagues or consulting literature reviews, online catalogs, and indexes and abstracts; ■ chaining—following chains of citations and other forms of referential connection between materials; ■ browsing—semi­directed searching in an area of potential interest, such as scanning published jour­ nals, tables of contents, references, and abstracts; ■ differentiating—using differences (authors or jour­ nal hierarchies) between sources as a filter on the nature and quality of the material examined; ■ monitoring—maintaining awareness of develop­ ments in an area through the monitoring of particular sources such as core journals, newspapers, confer­ ences, magazines, books, and catalogs; and ■ extracting—systematically working through a par­ ticular source to locate material of interest, for exam­ ple, sets of journals, collections of indexes, abstracts, or bibliographies.5 meho and tibbo revised ellis’s information­seeking model by studying the information­seeking behavior of social­science faculty who study stateless nations.6 they confirmed ellis’s model and derived four additional fea­ tures—accessing, networking, verifying, and information managing. accessing is getting hold of the materials or sources of information once they have been identified and located. networking includes communicating and maintaining a close relationship with a broad range of people such as friends, colleagues, and intellectu­ als. verifying is checking the accuracy of the informa­ tion found, and information managing includes filing, archiving, and organizing the collected information to facilitate research. yi shen yi shen (yishen@wisc.edu) is a ph.d. candidate in the school of library and information studies, university of

wisconsin-madison article title | author 5information seeking in academic research | shen 5 with the exception of ellis’s work in 1987–1990 and the follow­up study by meho and tibbo, studies inves­ tigating academic social scientists have been in steady decline since the mid­1970s.7 according to line, in an information world radically changed by the internet, it is essential to carry out new studies of information uses and needs.8 most of the studies discussed in this paper were conducted before the development of the internet. the present study focuses on the information­seeking behav­ ior of social scientists in a new information environment featuring the internet and other dramatic technological advances. kling and mckim pointed out the growing importance of information technology and the resulting major shifts in scientific practice.9 costa and meadows studied the impact of computer usage on scholarly com­ munication among social scientists and found that major changes in their communication habits were occurring.10 the most significant impacts of information technology were greater interactivity, widened community boundar­ ies, extended access to information, and an increasing democratization of the international research community. they suggested that the developments were influenced by new pressures (social, economic, political) from the research community and the institutional environment, and by newly available resources (infrastructure, ser­ vices, sources) being introduced into the academic envi­ ronment by information technology. it could be expected that social scientists’ information­seeking behavior would change within a new social­technical environment. the purpose of this study is to extend the findings of the pre­ vious studies by examining social scientists’ information needs and their activities and perceptions in relation to today’s information systems and services. this paper provides a theoretical framework for the study, discusses the methods for data collection and data analysis, and summarizes findings. finally, it discusses results, reflects on the theoretical and practical implica­ tions that ensue, and notes the limitations imposed by the study design. ■ theoretical framework the theoretical frame for this study is the idea of “com­ munities of practice.” wenger, mcdermott, and snyder define a community of practice as “a group of people who share a common concern, a set of problems, or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis.”11 within communities of practice, people share common values, observe and interact with each other, exchange views and ideas, and contribute to the knowl­ edge­creation process.12 according to wenger, communities of practice are combinations of three elements: a domain of knowledge, which defines the key issues in the community; a com­ munity of people who care about the domain; and the shared practice that they create.13 communities of prac­ tice are loosely connected, informal, and self­managed. they are about knowledge sharing, and the best way to share knowledge is through social interaction and infor­ mal relationship networks. effective communication and mutual understanding are important factors in fostering communities of practice. this form of social construction is highly situated and highly improvised.14 it essentially suggests that researching some thing is inseparable from its own historical and social locations of practice and should be carried out in the process of actually doing that thing.15 a process organizes knowledge in a way that is especially useful to practitioners whose shared learning brings value to a community.16 pragmatically, the exami­ nation of context­based research processes draws “atten­ tion away from abstract knowledge and cranial processes and situates it in the practice and communities in which knowledge takes on significance.”17 what is learned is highly dependent in the context on which the learning takes place, as it is central to the transfer and consump­ tion of information. this requires “looking at the actual practice of work, which consists of a myriad of fine­ grained improvisations that are unnoticed in any formal mapping of work tasks.”18 such beliefs are utilized in this present study to approach and explain information­seek­ ing behavior among social scientists. researchers used communities of practice in orga­ nization and business studies to investigate knowledge sharing and knowledge­creation processes within orga­ nizational settings to cultivate the building of knowl­ edge­management systems. researchers also used this approach in the field of computer­supported cooperative work (cscw) to study the social interactions of group­ ware systems and community computing and support systems. this study selected communities of practice as the theoretical frame because it has been widely applied in the study of knowledge sharing and has been tested and verified through empirical research. this study rep­ resents an exploration of the usefulness of communities of practice for research on information­seeking behavior within a knowledge­intensive scholarly community. the primary purpose of the present study is to pro­ vide empirical evidence on social scientists’ information seeking in scientific research. the main research ques­ tions are: (1) how do social scientists make use of different information sources and channels to satisfy their infor­ mation needs? (2) what strategies do they apply when seeking information for academic research? and, (3) what difficulties are encountered in searching for supporting 6 information technology and libraries | march 20076 information technology and libraries | march 2007 information? information service providers should find the results of this study interesting because identifying users’ perceptions of the information environment pro­ vides guidance for information­system development that will closely reflect or accommodate the information­seek­ ing activities of social scientists. ■ methods the research questions described in the preceding section were tested in the context of information use in scientific inquiry by faculty in the department of sociology at the university of wisconsin­madison during march and april 2003. the participants were selected from the faculty list on the department web page and then contacted by e­mail to arrange face­to­face interviews. four people were interviewed based on their willingness to par­ ticipate. three of them are full­time professors and have teaching experience of more than twenty years (one of them has been teaching for more than thirty years). the fourth is an assistant professor with four years of teaching experience. all of the participants are female. each inter­ view lasted from forty­five minutes to an hour. all participants were interviewed in their campus offices to allow for easy access to supporting materials as examples of how they go about their work. after explain­ ing her identity, the purpose of the research, and assuring the confidentiality of the interview, the researcher asked initial questions in a relatively structured way to glean background­related information and research context. the second part of the interview dealt with informa­ tion­related behavior, such as information sources and channels used to address research inquiry, and the major strategies for selecting needed information. the third part focused on problems the participants encountered in information seeking. the researcher took field notes and tape­recorded all interviews. as a consistency check, the participants were sometimes asked to comment on disciplinary work prac­ tices gleaned from other interviews. the selection of four participants reflected the practicalities of collecting data with limited time and resources. ■ findings based on the idea of communities of practice that what is learned is highly dependent on the context in which the learning takes place because it is central to the trans­ fer and consumption of information, the present study provides a holistic picture of information use situated in actual research practice and academic context among these social scientists.19 these findings can be summarized into several interrelated stages as shown in figure 1. the figure shows that the social scientists’ information seeking moves from academic information needs, choice of information sources, searching for information, to use of the information. the researchers move back and forth between stages until the information inquiry is satisfied. searching for information involves the implementation of strategies, confrontation of difficulties, and continuous decision making. choice of information channels goes through the whole information­seeking process based on researchers’ momentary or changing information activi­ ties and information needs. this figure is intended to provide a general view of the information seeking behav­ ior in this specific case, but is not intended to generate a model or pattern of information seeking. the findings are organized into the use of information resources and channels to address information inquiry, the strategies for information seeking, and the difficulties encountered in searching for information, which together constitute the major information­seeking practice of the participants. figure 1. stages of the social scientists’ information seeking article title | author 7information seeking in academic research | shen 7 ■ use of information resources and channels to address information needs information needs the respondents reported their research­oriented infor­ mation needs in the context of their research activities. those information needs can be grouped into seven cat­ egories. examples of responses follow. 1. general academic issues and current research dis­ courses in the field. “i find conferences are more useful for seeing what kinds of general things are going on. i guess some of these are research, some are academic politics kinds of things, and what’s happening in the disci­ pline as a whole.” “in conferences, you find out what other people are doing research on. the most current research is not published yet, so you know what’s happening now.” 2. feedback from colleagues on personal research. “the best thing about conferences is that when i present my own research, i get comments about it.” “you show your paper to people and ask them for comments, and they show you their papers and ask you for comments. this is kind of the normal part of academic life.” “i usually send a copy of a paper or something and get actual comments through e­mail.” 3. current research topics and activities of specific authors. “i’ll look for key people, and see what they’ve done. . . .” “knowing who is doing what where. . . .” “you sort of inevitably talk about your research with other people doing comparable research and find out what they are doing to keep current to what the different research projects are.” 4. existing datasets (existing survey research data­ bases) and statistics for secondary data analysis. “there are online statistical sources that i get to put in the papers.” “i use the internet to download all the . . . data that we analyze. . . .” “i do a lot of data research, so i use government sites on the internet, like the science’s bureau, or the national center for health statistics. we also have a little center for demography and ecology library. i use our in­house databases too.” “in social science, there are many existing sets of data. we have something called data and program library service here. they have all kinds of data­ bases that will tell you where there are data sources that have certain variables in them. . . . so you can go and do your own statistical analysis on those data.” 5. information needed for management purposes, such as the cooperation and coordination of research activities. “in this department, we conduct community busi­ ness by e­mail. we pass messages around. . . . a decision is usually made through this dialogue.” “i am constantly in interaction with people by e­ mail to cooperate on research projects.” 6. community recognition and inspirational support from colleagues. for example, one respondent commented, “in conferences, i feel invigorated when sitting and talking to field colleagues who are interested in my research. the whole conversa­ tion makes me feel excited and inspired.” another respondent indicated, “to see people face­to­face that you respect and they think your work is good, that’s good.” it is echoed by a third respondent: “you just talk about your work, and people act like what you are doing is very interesting, then it makes you more inspired.” those needs for information constitute a major research practice of the participants and thus determine how they go about seeking information. ■ information resources supporting information resources could be divided into internally built university resources and external resources. moreover, these internal and external resources could be further subdivided into human resources and nonhuman resources based on their physical forms. internal, nonhuman resources the participants identified two major categories of internal nonhuman information resources for academic research based on their intended use. the first of these categories is books and journals that are available in the university libraries for literature reviews and to provide awareness of current research. however, because of phys­ ical inconvenience, campus libraries are not often used. one participant indicated, “the library is down the hill, so even before there were lots of good internet resources, i wasn’t going down to the library a lot.” on the other hand, the participants reported that they frequently used the library online public access catalog (opac) to order 8 information technology and libraries | march 20078 information technology and libraries | march 2007 document delivery from the libraries. “i find madcat (the library online catalog system) very useful for a whole variety of specific searches for journals, books, and differ­ ent online information.” another participant remarked, “i can request a book online through the document deliv­ ery services.” another internal nonhuman resource consists of exist­ ing survey datasets that are collected by the center for demography and ecology library for secondary data analysis and research. it was indicated that in social sci­ ence, as more and more survey research databases were available, there was an increasing amount of research conducted on secondary data. the data and program library service provides all kinds of databases informing researchers of the location of data sources and the vari­ ables contained in certain datasets. external, nonhuman resources the participants identified three types of external non­ human resources based on their medium. some of these resources are purchased and managed internally by the campus libraries but developed and maintained exter­ nally by outside library and information professionals. one type is electronic resources, such as electronic news­ papers, external opacs, electronic full­text databases, online statistical reports, survey databases, and govern­ ment or personal web sites. some named examples include sociological abstracts, lexis­nexis, science bureau’s web site, the national center for health statistics web site, web of science, and online british newspapers. the second type is printed resources, such as books, newspapers and magazines, archives, and newspaper indexes that are available from outside of the campus. named examples include the paper indexes for the new york times and los angeles times back in the 1960s. the third type is audio­ video resources, such as radio broadcasts, tapes, video­ tapes, and television. one major finding was that the participants depended primarily on electronic information resources. all looked for information on both literature and research data via the internet. literally, each participant had her own fre­ quent visit to search engines or opacs for information on specific research topics and general research subjects. examples of responses include: “i start with internet explorer and go to google.” “i work a lot online. . . . i just do internet searches. “both these journal and newspaper databases, i use a lot for various purposes.” “i want to find out if there is work on this specific topic or concept. i would almost always start with sociological abstracts.” “the citation index is terrific for finding contempo­ rary work building on something important.” moreover, the respondents also conducted research on the internet to study web behavior or social networks on the internet. “there are more and more people actually doing research on the internet, studying web sites or connec­ tions between web sites. . . . they collect data online. . . .” “in social­movement research, more and more researchers study how people coordinate transactional movements, protest movements, various ethnic move­ ments, and political movements through the internet.” “online is a big way of doing cooperation as well as doing research. it is one of the reasons that we are inter­ ested in studying what kind of connections there are on the electronic network.” “a current research project that i am doing is looking at network of . . . web sites. so we are gathering primary data from the web sites.” thus, the electronic mechanism for information sys­ tems and services dominates the manner in which the participants carry out their research. internal, human resources the faculty participants were not only electronic­informa­ tion consumers, but also electronic­information producers. for example, one described, “i maintain my own web page, on which i post my research and add links to outside resources that i collected for years. i have my own gateway to organize the link pages, which can be used for my future reference and by my students. the library links to my web page as well.” moreover, this participant advocated the creation and collection of electronic materials by her col­ leagues as well. “it’s an evolving process. the more people put their information on the internet, the more useful it is to be on the internet. we are right in that transition.” the department can easily take a step further to build a shared pool of information and information resources in its internal system. a second type of internal human resources comes from the technical staff who provided announcements of technical developments and product information, as well as technical assistance for social­science research. working as the social science computing cooperative (sscc), the technical staff provides the faculty with detailed instruc­ tions and useful tips for creating electronic materials as well as with directions for publishing them. librarians, as a third type of human resource, provided reference services and collected necessary information resources for their academic research. external, human resources the external human resources that the respondents gathered and contacted are of two types: people shar­ article title | author �information seeking in academic research | shen � ing similar research interests and concerns, and people having different fields of interest. the former types were valued for supporting suggestive and creative commu­ nication and interaction as well as potential cooperation. for example, “when it comes to really think[ing] about things, sit down in one place and talk, and then stuff comes out. you don’t even know what you are thinking until you sit down and talk to people. it’s idea generating.” “knowing who is doing what where in the field is important. . . . i am working on a . . . research topic, which requires the awareness of other people with similar inter­ est around the world. . . . i cooperate with the scholars from different countries and with different knowledge background.” the latter types are used for current awareness of research works in other fields and general disciplinary activities and academic trends. for example, “i need to know people who know what’s going on in other fields, and they tell me what’s going on.” “i get a lot in terms of contemporary research at con­ ferences, which are useful for things that haven’t been published in journals.” “[a conference] will generate a lot of interesting inter­ change.” “[at conferences], i think about how what other people are doing is related to what i would want to do, or how they can do it differently. a lot of times, i think about whether the methods they are using would be useful for my work at all.” ■ channels the major information channels through which the par­ ticipants delivered and exchanged information included e­mail, telephone, face­to­face communication, and proj­ ect reports or other documents. e­mail was a domi­ nant communication and information­acquisition tool in research. face­to­face or oral communication channels in this case were often used as a supplementary means. “mostly, e­mail is how i communicate with people, occasionally telephone, but not very often. even with people here and we can walk right next door, mostly we just e­mail each other. it’s nice, because you have a record.” “i get hundreds of e­mails a week. . . . i live on e­mail. my colleagues know i am easier to reach by e­mail than in person.” “[face­to face] it’s just the more personal and emo­ tional mode [of communication] . . . you can see the person’s expression, and figure out what they are really thinking.” e­mail communication helped accomplish several scientists’ tasks, including quick exchange of timely infor­ mation, teamwork coordination, non­work­oriented mes­ sage exchange, field discussion, field information seeking and finding communities of interest. for example, one participant indicated the coordination of community activities through e­mail. in this department, we conduct community business by e­mail. community members rarely meet face to face. the chairperson finds out what the research task is, and sends out messages. people exchange opinions through e­mail messages. and a decision is usually made through this dialogue, instead of talking face to face. when scholars are going to have a face­to­face meet­ ing, they deliver the data, records, and reports before­ hand, and share their initial viewpoints with supporting information through e­mail. the following factors affected a scholar’s choice of channels for information delivery and exchange: the char­ acteristics of the information receiver, the characteristics of the information, the task or purpose of delivering or sharing information, and the immediacy of response. for example, one respondent mentioned that she usu­ ally delivered data, records, and research documents via e­mail for formal announcement and record keeping by the receivers. when there was no stress of immediate response, she preferred e­mail communication for the thoughtful input and feedback allowed by the asynchro­ nous­exchange feature of e­mail. “intellectual questions are more easily handled by e­mail because i have the time to think about it and formulate my responses.” she con­ tinued, “i usually e­mail a copy of my paper to colleagues for detailed feedback.” in another case, a participant indicated, “some of us are well aware that e­mail is archived, it’s not anonymous and not private. if you are concerned about something and want to say something that you don’t want to have an e­mail record of, you may want to go to talk to some­ body about it, instead of writing it in an e­mail.” another participant explained that because of her research topics, she usually adopted the face­to­face method of communication and attended all kinds of international academic conferences. in other circum­ stances, when collecting opinions for resolving certain questions, she chose to use e­mail. ■ strategies for information seeking the participants indicated certain strategies applied to gathering information and tracking resources to address 10 information technology and libraries | march 200710 information technology and libraries | march 2007 their information needs. those strategies with response examples are: 1. extracting abstracts: “i use abstracts to get the parameters of what’s happening and then know more narrowly where to focus.” 2. tracking citations: “the citation index is terrific for finding contemporary work” that builds on previ­ ous major work in a subject area. 3. restricting the search to a limited set of sources or types of sources to achieve satisfactory results within an acceptable timeline. 4. constantly filtering and interpreting the search results by referring to the summary description of web sites: “in most searches that i do, the first ten hits are book dealers. i don’t bother with them. i go to the next page and try. . . . i look at the summary of what the site is and try to figure out what the worthy things are.” 5. avoiding search terms prone to commercial infor­ mation: “when searching for something without a lot of commercial stuff, you are more likely to get what you want on the top.” 6. setting the default for the number of search results with consideration of information completeness, information usefulness, importance of research, and timeliness: for example, one participant stated, “i usually set my least default to a hundred cita­ tions. five hundred is too many, but it depends on what you’re looking for, how much you care about your findings, how much faith you have for the existence of useful information. if you think it’s not worth a minute of your time, you just forget it. but if you are sure it’s there, you just have to keep looking for and work[ing] harder at it.” as shown in the findings, the participants employed certain criteria for evaluation of the information they gathered. those judgment criteria were: importance of research, usefulness, accuracy, completeness, and timeli­ ness. the results imply that to accomplish the research tasks on hand in a fast­paced and distributed digital­ information environment, the practicalities of time and human effort have come into play in the ways in which the participants sought information. ■ difficulties in seeking supporting information the problems encountered by the participants when col­ lecting information through various resources were iden­ tified and are grouped into categories, including: ■ information is scattered in different places and with different qualities; it is difficult to have a complete and valuable picture of a research phenomenon. the participants described this difficulty as “how tricky computerized search is.” ■ there is too much information on the internet to filter, and the current search techniques and ranking tools are not intelligent enough to capture the most relevant information of interest. the participants described trying alternative search strategies as a “game­playing” and “brainstorming” process. ■ no sources of information or mechanisms assist in the identification of people with similar research interests and their activities in the broad virtual space. for example, one participant described: i am trying to find what’s in public debate on con­ troversial topics. and it’s very common to have trouble finding both sides of the debate. i started with diffuse searches on the internet trying to see if i can find the potential academic community and tag into their debate. i basically searched on [the search term] on the whole internet because i had no idea where it would be, who got involved, and how it was formed. when doing [the research] issue, it’s easy to find the people in favor of [a topic], but difficult to find anybody who was an opponent. eventually, i got hundreds of hits [search results], and i had to wade through a lot of proponents to find the opponents. sometimes, it’s an issue to find [an] ethnic minority perspective of a topic. ■ technology upgrades and system integration arouse another concern. as one participant expressed it, “technology is changing [so] fast that lots of com­ puter files from the 1970s are no longer readable. the danger of an information system lies in the tradeoff between the accessibility provided by digitization and the long­term survival of intellectual proper­ ties.” ■ there are no digital sources of information for some historical documents and no retrievable data­ bases for book chapters. one participant noted, “the online strategy is very good for really current stuff, but not for older stuff. the people who started the . . . research were actually writing before the online revolution, so they are not turning up so much in keyword searches online.” another participant also mentioned the inconvenience of using hard­copy indexes for newspapers from the 1960s and archival data that go back to the 1970s and 1980s. ■ discussion this study shows how the ‘communities of practice’ perspective situates the process of using information in the actual practice of scientific research. it provides an information context in which knowledge takes on sig­ article title | author 11information seeking in academic research | shen 11 nificance. the results provide empirical evidence of the participants’ activities as well as insights into the ways they seek information. in his discussion of user­oriented evaluation and qualitative analysis of information use, ellis emphasized a small­scale qualitative analysis of users’ perceptions of system performance to construct insights into the complex reality of the information environment.20 he argued that a detailed understanding of the complexity and interaction of information systems and services and their users can be used to explain problems and provide guidance on the development of information systems. the present study is in accord with ellis’s idea by focus­ ing on a specific sample of academic social scientists working in a university setting. the choice of university of wisconsin­madison is based on the grounds of conve­ nience and ease of access. the restriction to one specific sample also avoids the added complexity and compound problems of information use situated in different practice and contexts. ellis also considered the feasibility of interviews to “provide enough information for a detailed and accurate account of the perceptions of the social scientists of their information­seeking activities to be made, and to enable an authentic picture to be constructed of those activi­ ties.”21 he thought the information­seeking activities of social scientists were too diffuse to carry out triangulation of methods. by applying the interview method, this cur­ rent study complies with ellis’s suggestion. on the other hand, ellis’s information­seeking behav­ ior­model of social scientists presented six generic fea­ tures. these conclusions are far too general for specific application. from the perspective of communities of practice, the current study examines the way social sci­ entists use information in their research practices and specific circumstances; it also presents specific informa­ tion­related behavior, strategies, and difficulties. this study also extends the understanding of the way infor­ mation is used by social scientists in a new information environment with dramatic technical advances. the findings of this study support the conclusions of kling and mckim and costa and meadows by showing the growing importance of information technology and the resulting major shifts in information­seeking practice among social scientists.22 unlike research findings prior to the 1990s, the social scientists in this study make exten­ sive use of a variety of information sources and channels, primarily electronic­information systems and services, in seeking information. in the new information environ­ ment, these new information mechanisms also presented limitations and difficulties. moreover, many lis researchers have examined users’ relevance criteria in information seeking.23 great emphasis is given to the “situational dynamism of user­ centered relevance estimation.”24 situated in their research practices, the present study also identified the social sci­ entists’ applications of certain criteria for evaluation of information. although the small­scale study has limitations for research generalization, the rich description of social sci­ entists’ perspective on the information environment has some practical implications for information­system­and­ service design for academic social scientists. ■ plan for system-to-system integration this study identified technology upgrades and sys­ tem­integration problems existing in current academic information systems. technology was developed and applied without the capability of intergenerational com­ munications and transactions at the cost of intellectual properties. kling and star addressed the same issue that “computerized systems appear like the layers of an archaeological dig, with newer systems built upon older systems with various workplace surveillance capa­ bilities.”25 they stated that such “legacy systems” are fragile and inflexible for information use and knowledge management. therefore, planning for system integration should be underway. ■ enhance the web resource-retrieval system the study identified the difficulties encountered by fac­ ulty in locating relevant, complete, and valuable informa­ tion effectively and efficiently on the large and dynamic web. an advanced web resource system thus is required that allows web content to be indexed and retrieved more intelligently. moreover, the findings of information­seek­ ing strategies in this case study suggest a one­way user­ system interaction process. there is no interactive query refinement between the user and the system. thus, the users have to brainstorm and play with alternative search strategies in the hope of significant results. to enhance system effectiveness, a relevance­feedback mechanism that takes into account the users’ relevance judgment is thus needed. this mechanism should have a two­way user­system interaction component. ■ construct an internal information system the findings of the study point to a need for a shared pool of information resources in the university of wisconsin– madison department of sociology. through the leverage and reuse of existing internal knowledge assets in the 12 information technology and libraries | march 200712 information technology and libraries | march 2007 department, this system could help collectively create or gather information resources for cross­reference by colleagues. ■ construct a collaborative information mechanism for the social-scientific community according to the findings, there are no sources of infor­ mation or mechanisms that assist the identification of people with similar research interests and their activi­ ties on the broad virtual space. however, awareness of shared interests and experiences constitutes an important external human resource that is valued for suggestive and creative interaction and for potential cooperation. thus, a collaborative information mechanism for identification with personal academic interests will be helpful. ■ limitations certain limitations inherent in the study need to be acknowledged. due to the time and resource constraints, the study sample includes only four scholars. given this small sample, results cannot be generalized. although ellis mentioned the feasibility of interviews in a user­ oriented study of information use, dependence on a single method has the disadvantages of the restriction of views. for example, interviewer characteristics, expecta­ tions, and verbal idiosyncrasies, and participants’ socially desirable responses are recognized in many studies as potential sources of method biases (podsakoff et al.).26 if time and resources permit, triangulation of methods—for example, combining interviews with observations and diaries—would increase the level of specificity and justify the validity and reliability of the research results. ■ conclusion drawing upon the idea of communities of practice that what is learned: (1) is dependant on the context in which the learning takes place, and (2) is central to the transfer and consumption of information, this study examined the information­seeking behavior of four social scien­ tists. results were drawn about their use of information resources and information channels to meet their infor­ mation inquiries, their strategies for information seeking, and the difficulties encountered in searching for relevant information, situated in the course of their actual scien­ tific research. this work has two primary contributions. first, it provides a rich description of social scientists’ per­ spectives on their research­oriented information­seeking behavior in the context of today’s information environ­ ment. second, it situates information seeking behavior in a socially constructed practice and presents specific features of information seeking. these results will help refine the understanding of the dynamic relationship between information systems and services and their users within scientific research. several areas remain for future research. researchers could make a comparative study of academics in differ­ ent institutional settings. future research could also study the dynamic interaction of information systems and ser­ vices and their users within each stage of ellis’s model of information­seeking patterns among social scientists to get insights into the specific features of their information seeking behaviors and to enrich their general patterns of information inquiry with specific details. research on information­seeking behaviors of social scientists could also focus on specific research tasks or certain research stages to decide differences or similarities of informa­ tion­seeking behaviors across academic practice. similar research could also be done on faculty in other disci­ plines. references 1. m. b. folster, “information­seeking patterns: social scien­ tists,” the reference

tags collected over a thirty-day period from the daily tag logs of del.icio.us, furl, and technorati. the tags were evaluated against the national information standards organization (niso) guidelines for the construction of controlled vocabularies. the results indicate that the tags correspond closely to the niso guidelines pertaining to types of concepts expressed, the predominance of single terms and nouns, and the use of recognized spelling. problem areas pertain to the inconsistent use of count nouns and the incidence of ambiguous tags in the form of homographs, abbreviations, and acronyms. with the addition of guidelines to the construction of unambiguous tags and links to useful external reference sources, folksonomies could serve as a powerful, flexible tool for increasing the user-friendliness and interactivity of public library catalogs, and also may be useful for encouraging other activities, such as informal online communities of readers and user-driven readers’ advisory services. o ne of the most daunting challenges of information management in the digital world is the ability to keep, or refind, relevant information; book­ marking is one of the most popular methods for storing relevant web information for reaccess and reuse (bruce, jones, and dumais 2004). the rising popularity of social bookmark managers, such as del.icio.us, addresses these concerns by allowing users to organize their bookmarks by assigning tags that reflect directly their own vocabu­ lary and needs. the collection of user­assigned tags is referred to commonly as a folksonomy. in recent years, significant developments have occurred in the creation of customizable user features in public library catalogs. these features offer clients the opportunity to customize their own library web pages and to store items of interest to them, such as book lists. client participation in these interfaces, however, is largely reactive; clients can select items from the catalog, but they have little ability to orga­ nize and categorize these items in a way that reflects their own needs and language. digital document repositories, such as library cata­ logs, normally index the subject of their contents via key­ words or subject headings. traditionally, such indexing is performed either by an authority, such as a librarian or a professional indexer, or is derived from the authors of the documents; in contrast, collaborative tagging, or folkson­ omy, allows anyone to freely attach keywords or tags to content. demspey (2003) and ketchell (2000) recommend that clients be allowed to annotate resources of interest and to share these annotations with other clients with similar interests. folksonomies can thus make significant contributions to public library catalogs by enabling cli­ ents to organize personal information spaces; namely, to create and organize their own personal information space in the catalog. clients find items of interest (items in the library catalog, citations from external databases, external web pages, and so on) and store, maintain, and organize them in the catalog using their own tags. in order to more fully understand these applications, it is important to examine how folksonomies are struc­ tured and used, and the extent to which they reflect user needs not found in existing lists of subject headings. the purpose of this proposed research is thus to examine the structure and scope of folksonomies. how are the tags that constitute the folksonomies structured? to what extent does this structure reflect and differ from the norms used in the construction of controlled vocabular­ ies ,such as library of congress subject headings? what are the strengths and weaknesses of folksonomies (for example, reflect user need, ambiguous headings, redun­ dant headings, and so forth)? this article will examine a selection of tags obtained from three folksonomy sites, del.icio.us (referred to henceforth as delicious), furl, and technorati, over a thirty­day period. the structure of these tags will be examined and evaluated against section 6 of the niso guidelines for the construction of controlled vocabularies (niso 2005), which looks specifically at the choice and form of terms. ■ definitions of folksonomies folksonomies have been described as “user­created meta­ data . . . grassroots community classification of digital assets” (mathes 2004). wikipedia (2006) describes a folksonomy as “an internet­based information retrieval methodology consisting of collaboratively generated, open­ended labels that categorize content such as web pages, online photographs, and web links.” the concept of collaboration is attributed commonly to folksonomies (bateman, brooks, and mccalla 2006; cattuto, loreto, and pietronero 2006; fichter 2006; golder and huberman the structure and form of folksonomy tags: the road to the public library catalog louise f. spiteri louise f. spiteri (louise.spiteri@dal.ca) is associate professor at the school of information management, dalhousie university, halifax, nova scotia, canada. this research was funded by the oclc/alise library and information science research grant program. the structure and form of folksonomy tags | spiteri 13 1� information technology and libraries | september 20071� information technology and libraries | september 2007 2006; mathes 2004; quintarelli 2005; udell 2004). thomas vander wal, who coined the term folksonomy, argues, however, that: the definition of folksonomy has become completely unglued from anything i recognize. . . . it is not col­ laborative . . . it is the result of personal free tagging of information and objects (anything with a url) for one’s own retrieval. the tagging is done in a social environment (shared and open to others). the act of tagging is done by the person consuming the informa­ tion” (vanderwal.net 2005). it may be more accurate, therefore, to say that folk­ sonomies are created in an environment where, although people may not actively collaborate in their creation and assignation of tags, they may certainly access and use tags assigned by others. folksonomies thus enable the use of shared tags. folksonomies are used primarily in social bookmark­ ing sites, such as delicious (http://del.icio.us/) and furl (http://www.furl.net/), which allow users to add sites they like to their personal collections of links, to organize and categorize these sites by adding their own terms, or tags, and to share this collection with other people with the same interests. the tags are used to collocate bookmarks within a user’s collection and bookmarks across the entire system, so, for example, the page http://del.icio.us/tag/blogging will show all bookmarks that are tagged with blogging by any member of the delicious site. ■ benefits of folksonomies quintarelli (2005) and fichter (2006) suggest that folk­ sonomies reflect the movement of people away from authoritative, hierarchical taxonomic schemes that reflect an external viewpoint and order that may not necessarily reflect users’ ways of thinking. “in a social distributed environment, sharing one’s own tags makes for innova­ tive ways to map meaning and let relationships naturally emerge” (quintarelli 2005). vander wal (2006) adds that “the value in this external tagging is derived from people using their own vocabulary and adding explicit mean­ ing, which may come from inferred understanding of the information/object.” an attractive feature of folksonomies is their inclusive­ ness; they reflect the vocabulary of the users, regardless of viewpoint, background, bias, and so forth. folksonomies may thus be perceived to be a democratic system where everyone has the opportunity to contribute and share tags (kroski 2006). the development of folksonomies may reflect also the difficulty and expense of applying con­ trolled taxonomies to the web: building, maintaining, and enforcing a sound, controlled vocabulary is often simply too expensive in terms of development time and of the steep learning curve needed by the user of the system to learn the classification scheme (fichter 2006; kroski 2006; quintarelli 2005; shirky 2004). a further limitation of taxonomies is that they may become outdated easily. new concepts or products may emerge that are not yet included in the taxonomy; in comparison, folksonomies easily accommodate such new concepts (fichter 2006; mitchell 2005; wu, zubair, and maly, 2006). shirky (2004) points out that the advantage of folksonomies is not that they are better than controlled vocabularies, but that they are better than nothing. folksonomies follow desire lines, which are expres­ sions of the direct information needs of the user (kroski 2006; mathes 2004; merholz 2004). these desire lines also may reflect the needs of communities of interest: tag­ gers who use same set of tags have formed a group and can seek each other out using simple search techniques. “tagging provides users an easy, yet powerful method to express themselves within a community” (szekely and torres 2005). ■ weaknesses of folksonomies folksonomies share the problems inherent to all uncon­ trolled vocabularies, such as ambiguity, polysemy, syn­ onymy, and basic level variation (fichter 2006; golder and huberman 2006; guy and tomkin 2006; mathes 2004). the terms in a folksonomy may have inherent ambiguity as different users apply terms to documents in different ways. the polysemous tag port could refer to a sweet fortified wine, a porthole, a place for loading and unloading ships, the left­hand side of a ship or air­ craft, or a channel endpoint in a communications system. folksonomies do not include guidelines for use or scope notes. folksonomies provide for no synonym control; the terms mac, macintosh, and apple, for example, are all used to describe apple macintosh computers. similarly, both singular and plural forms of terms appear (for example, flower and flowers), thus creating a number of redun­ dant headings. the problem with basic level variation is that related terms that describe an item vary along a continuum of specificity ranging from very general to very specific, so, for example, documents tagged perl and javascript may be too specific for some users, while a document tagged programming may be too general for others. folksonomies provide no formal guidelines for the choice and form of tags, such as the use of com­ pound headings, punctuation, word order, and so forth; for example, should one use the tag vegan cooking or cooking, vegan? guy and tomkin (2006) provide some general suggestions for tag selection best practices, such as the use of plural rather than singular forms, the use article title | author 15the structure and form of folksonomy tags | spiteri 15 of underscore to join terms in a multiterm concept (for example, open_source), following conventions estab­ lished by others, and adding synonyms. these sugges­ tions are rather too vague to be of much use, however; for example, under what circumstances should singular forms be used (such as noncount nouns), and how should synonyms be linked? ■ applications of folksonomies other than social bookmarking sites, folksonomies are used in commercial shopping sites, such as amazon (http://www.amazon.com/), where clients tag items of interest; these tags can be accessed by people with similar interests. platial (http://www.platial.com/ splash) is used to tag personal collections of maps. examples of the use of folksonomies for intranets include ibm’s social bookmarking application dogear, which allows people to bookmark pages within their intranet (http://domino.watson.ibm.com/cambridge/ research.nsf/99751d8eb5a20c1f852568db004efc90/ 1c181ee5fbcf59fb852570fc0052ad75?opendocument), and scuttle (http://sourceforge.net/projects/scuttle/), an open­source bookmarking project that can be hosted on web servers for free. penntags (http://tags.library. upenn.edu/) is a social bookmarking service offered by the university of pennsylvania library to its community members. steve museum is a project that is investigating the incorporation of folksonomies into museum catalogs (trant and wyman 2006). another potential application of folksonomies is to public library catalogs, where users can organize and tag items of interest in user­specific folders; users could then decide whether or not to post the tags publicly (spiteri 2006). ■ analyses of folksonomies analysis of the structure, or composition, of tags has thus far been limited; there has been more emphasis placed upon the co­occurrence of tags and their frequency of use. cattuto, loreto, and pietronero (2006) applied a stochas­ tic model of user behavior to investigate the statistical properties of tag co­occurrence; their results suggest that users of collaborative tagging systems share universal behaviors. michlmayr (2005) compared tags assigned to a set of delicious bookmarks to the dmoz (http://www. dmoz.org/) taxonomy, which is designed by a commu­ nity of volunteers. the study concluded that there were few instances of overlap between the two sets of terms. mathes (2004) provides an interesting analysis of the strengths and limitations of the structure of delicious and flickr, but does not provide an explanation of the meth­ odology used to derive his observations; it is not clear, for example, for how long he studied these two sites, how many tags he examined, what elements he was looking for, or what evaluative criteria he applied. golder and huberman (2006) conducted an analysis of the structure of collaborative tagging systems, look­ ing at user activity and kinds and frequencies of tags. specifically, golder and huberman looked at what tags delicious members assigned and how many bookmarks they assigned to each tag. this study identified a number of functions tags perform for bookmarks, including iden­ tifying the: ■ subject of the item; ■ format of the item (for example, blog); ■ ownership of the item; and ■ characteristics of the item (for example, funny). while the golder and huberman study provides an important look at tag use, their study is limited in that they examined only one site for a period of four days; their results are an excellent first step in the analysis of tag use, but the narrow focus of their population and sample size means that their observations are not easily generalized. furthermore, this study focuses more on how bookmarks are associated with tags (for example, how many bookmarks are assigned per tag and by whom) rather than at the structural composition of the tags themselves. guy and tonkin (2006) collected a random sampling of tags from delicious and flickr to see whether “popular objections to folksonomic tagging are based on fact.” the authors do not explain, however, over what period the tags were acquired (for example, over a one­day period, over a month), nor to they provide any evaluative criteria. the tags were entered into aspell, an open source spell checker, from which the authors concluded that 40 percent of flickr and 28 percent of delicious tags were either mis­ spelled, encoded in a manner not understood by aspell, or consisted of compound words of two or more words. tags did not follow convention in such areas as the use of case or singular versus plural forms. while this study certainly focuses upon the structure of the tags, the bases for the authors’ conclusions are problematic. it is not clear that the use of a spell checker is a sufficient measure of quality. does the spell checker allow for cultural variations in spell­ ing (for example, labor or labour)? how well­recognized and comprehensive is the source vocabulary for this spell checker? furthermore, if a tag does not exist in the spell checker, does this necessarily mean that the tag is incor­ rect? tags may include several neologisms, such as podcasting, that may not yet exist in conventional dictionaries but are well­recognized in a particular domain. the authors do not mention whether they took into account the cor­ 16 information technology and libraries | september 200716 information technology and libraries | september 2007 rect use of the singular form of such tags as noncountable nouns (for example, air) or tags that describe disciplines or emotions (for example, history and love). if a named entity (person or organization) was not recognized by aspell, does this mean that the tag was classified as incorrect? lastly, the authors seem to imply that compound words of two or more words are necessarily incorrect, which may not be the case (for example, open source software). the pitfalls of folksonomies have been well­docu­ mented; what is missing is an in­depth analysis of the linguistic structure of tags against an established bench­ mark. while popular opinion suggests that folksonomies suffer from ambiguous and inconsistent structure, the actual extent of these problems is not yet clear; further­ more, analyses conducted so far have not established clear benchmarks of quality pertaining to good tag structure. although there are no guidelines for the construction of tags, recognized guidelines do exist for the construction of terms that are used in taxonomies. although these guidelines discuss the elucidation of inter­term relation­ ships (hierarchical, associative, and equivalent), which does not apply to the flat space of folksonomies, they contain sections pertaining to the choice and formation of concept terms that may, in fact, have relevance for the construction of tags. ■ methodology selection of folksonomy sites tags were chosen from three popular folksonomy sites: delicious, furl, and technorati (http://www.technorati. com/). delicious and furl function as bookmarking sites, while technorati enables people to search for and organize blogs. these sites were chosen because they provide daily logs of the most popular tags that have been assigned by their members on a given day. the daily tag logs from each of the sites were acquired over a thirty­day period (february 1–march 2, 2006). the daily tags for each site were entered into an excel spreadsheet. a list of unique tags for each site was compiled after the thirty­day period; unique refers to the single instance of a tag. some of the tags were used only once during the thirty­day period, while others, such as travel, occurred several times, so travel appears only once in the list of unique tags. variations of the same tag—for example, car or cars, cheney or dick cheney—were considered to constitute two unique tags. only english­language tags were accumulated. the analysis of the tag structure in the three lists was conducted by applying the niso guidelines for thesaurus construction, which are the most current set of recognized guidelines for the: contents, display, construction . . . of controlled vocabu­ laries. this standard focuses on controlled vocabularies that are used for the representation of content objects in knowledge organization systems including lists, syn­ onym rings, taxonomies, and thesauri (niso 2005, 1). while folksonomies are not controlled vocabularies, they are lists of terms used to describe content, which means that the niso guidelines could work well as a benchmark against which to examine how folksonomy tags are structured as well as the extent to which this structure reflects the widely accepted norm for controlled vocabu­ laries. section 6 of the guidelines (term choice, scope, and form) was applied to the tags, specifically the following elements (see appendix a for the expanded list): 6.3 term choice 6.4 grammatical form of terms 6.5 nouns 6.6 selecting the preferred form only those elements in section 6 that were found to apply to the lists of unique tags are included in appendix a. for each site, the section 6 elements were applied to each unique tag; for example, it was noted whether a tag consists of one or more terms, whether the tag is a noun, adjective, or adverb, and so on. the frequency of occur­ rence of the section 6 elements was noted for each site and then compared across the three sites in order to determine the existence of any patterns in tag structure and the extent to which these patterns reflect current practice in the design of controlled vocabularies. definition and disambiguation of tags the meanings of the tags were determined based upon (1) the context of their use; and (2) their definition in three external sources, namely merriam webster online dic­ tionary (http://www.m­w.com/); google (http://www. google.com/); and wikipedia (http://www.wikipedia. org/). merriam­webster was used specifically to define all tags other than those that constitute unique entities (for example, named people, places, organizations, or products) and to determine the various meanings of tags that are homographs (for example, art or web). the actual concept represented by homographs was determined by examin­ ing the sites or blogs to which the tag was assigned. merriam­webster also was used to determine the grammatical form of a tag; for example, noun, verbal noun, adjective, or adverb. determining verbal nouns proved to be complicated, especially given that niso relies only on examples to illustrate such nouns. some tags could serve as both verbal and simple nouns; for example, the tag clipping could describe the activity to clip or an item that has been clipped, such as a newspaper article title | author 17the structure and form of folksonomy tags | spiteri 17 clipping. similarly, does skiing refer to an activity, or the sport? if the dictionary defined a tag as an activity, the tag was classified as a verbal noun. in the case of tags that were defined as both verbal nouns and simple nouns, the context in which the tag was used determined the final classification. the dictionary also was used to determine the type of concept represented by a tag. the niso guidelines do not define any of these seven types of concepts outlined in section 6.3.2; they provide only a short list of examples for each type. if the term represented by the tag was defined as an activity, property, material, event, discipline or field of study, or unit of measurement, it was classified as such unless the context of the tag suggested otherwise. if none of these six types was defined in the dictionary, the default value of thing was assigned to the tag. these definitions were then compared to the context in which the tag was used. in the case of the tag art, for example, an examination of the sites associated with this tag indicated that it refers to art objects, rather than the discipline, so it was classified as a thing. merriam­webster was used to determine whether a tag constitutes a recognized term in standard english (both united states and united kingdom variants); for example, the tag blogs is a recognized term in the dictionary, while podcasting is not. niso does not provide a clear definition of slang, neologism, or jargon, other than to say that they are nonstandard terms not generally found in dictionaries. is the term podcasting, for example, an instance of slang, jargon, or neologism? at what point does jargon become a neologism? because of the difficulty of distinguishing among these three categories, it was decided to use the broader category nonstandard terms to cover tags that (1) could not be found in the dictionary; or (2) are designated as vulgar or slang in the dictionary. google and wikipedia were used to define the mean­ ings of tags that constitute unique entities. wikipedia also was used to distinguish the various meanings of tags that constitute abbreviations or acronyms via its disambigua­ tion pages; for example, the tag nfl is given eight pos­ sible meanings. in this case, the tag nfl is used to refer specifically to the national football league, so the tag is a homograph, noun, and unique entry. ■ tagging conventions and guidelines of the folksonomy sites delicious delicious defines tags as: one­word descriptors that you can assign to your bookmarks. . . . they’re a little bit like keywords but non­hierarchical. you can assign as many tags to a bookmark as you like and easily rename or delete them later. tagging can be a lot easier and more flexible than fitting your information into preconceived categories or folders” (del.icio.us 2006a). the delicious help page for tags encourages people to “enter as many tags as you would like, each separated by a space” in the tag field. this paragraph explains briefly that two lists of tags may appear under the entry form used to enter a bookmark. the first list consists of popular tags assigned by other people to the bookmark in question, while the second consists of recommended tags, which contains a combination of tags that have been assigned by the client in question as well as other users (del.icio.us 2006b). it is not clear how the two lists differ in that they both contain tags assigned by other people to the bookmark at hand. the only tangible guideline provided about how tags should be structured is the sentence “your only limitation on tags is that they must not include spaces.” delicious thus addresses only indirectly the fact that it does not allow multiterm tags; the examples provided suggest ways in which compound terms can be expressed; for example, san­francisco, sanfranciso, san.franciso (del. ico.us 2006b). punctuation thus appears to be allowed in the construction of tags, which is confirmed by the sug­ gestion that asterisks may be used to rate bookmarks: “a tag of * might mean an ok link, *** is pretty good, and a bookmark tagged ***** is awesome” (del.icio.us 2006b). it is thus possible that tags may not consist of recognizable terms, even though asterisks are neither searchable nor indicative of content. furl the furl web site uses the term topics rather than tags, but provides no guidelines or instructions for how to con­ struct these topics. furl mentions only that when entering a bookmark, “a small window will pop up. it should have the title and url of the page you are looking at. enter any additional details (i.e., topic, rating, comments) and click save” (furl 2006). furl provides all users with a list of default topics to which one can add at will. furl provides no guidelines as to whether single or multiword topics may be used; it is only by trial and error that the user discovers that the latter are, in fact, allowed. technorati in its tags help page, technorati encourages users to “think of a tag as a simple category name. people can categorize their posts, photos, and links with any tag that makes sense” (technorati 2006). a tag may be “anything, but it should be descriptive. please only use tags that are rel­ evant to the post” (technorati 2006). technorati tags are 1� information technology and libraries | september 20071� information technology and libraries | september 2007 embedded into individual blogs via the link rel=”tag”; for example: <a href=”http://technorati.com/tag/ global+warming” rel=”tag”>global warming</a>. the tag will appear as simply global warming. no other guidelines are provided about how tags should be constructed. as can be seen, the three folksonomy sites provide very few guidelines or conventions for how tags should be constructed. users are not pointed to the common problems that exist in uncontrolled vocabulary, such as ambiguous headings, homographs, synonyms, spelling variations, and so forth, nor are suggestions made as to the preferred form of tags, such as nouns, plural forms, or the distinction between count nouns (for example, dogs) and mass nouns (for example, air). given this lack of guidance, it is not unreasonable to assume that the tags acquired from these sites will vary considerably in form and structure. ■ findings unless stated otherwise, the number of tags per folk­ sonomy site is 76 for delicious, 208 for furl, and 229 for technorati. homographs the niso guidelines recommend that homographs— terms with identical spellings but different meanings— should be avoided as far as possible in the selection of terms. homographs constitute 22 percent of delicious tags, 12 percent of furl tags, and 20 percent of technorati tags. unique entities constitute a significant proportion of the homographs in all three sites, with 71 percent in delicious, 43 percent in furl, and 55 percent in technorati. the most frequently occurring homographs across the three sites consist predominantly of computer­related terms, such as ajax and css. single-word versus multiword terms the niso guidelines recommend that terms should represent a single concept expressed by a single or mul­ tiword term, as needed. single­term tags constitute 93 percent of delicious tags, 76 percent of furl tags, and 80 percent of technorati tags. the preponderance of single tags in delicious may reflect the fact that it does not allow for the use of spaces between the different elements of the same tag; for example, open source. types of concepts niso provides a list of seven types of concepts that may be represented by terms; while this list is not exhaustive, it represents the most frequently occurring types of con­ cept. table 1 shows the percentage of tags that correspond to each of the seven types of concepts. tags that represent things are clearly predominant in the three sites, with activities and properties forming a distant second and third in importance. none of the tags represent events or measures, and only a fraction of the technorati tags represent materials. the niso guidelines provide no indication of the expected distribution of the types of concepts, so it is difficult to determine to what extent the three folksonomy sites are consistent with other lists of descriptors. none of the tags fell outside the scope of the seven types of concepts. unique entities unique entities may represent the names of people, places, organizations, products, and specific events (niso 2005). unique entities constitute 22 percent of delicious tags, 14 percent of furl tags, and 49 percent of technorati tags. there is no consistency in the percentage of unique enti­ ties: technorati has nearly twice the percentage of tags than delicious has, and nearly triple the percentage of tags than furl has. computer­related products constitute 100 percent of the unique entities in delicious, 63 percent in furl, and 38 percent in technorati. the remainder of the unique entities in furl and technorati represent places, people, and corporate bodies. the unique entities in technorati are closely related to developments in current news events, an occurrence that is likely due to the site’s focus on blogs rather than web sites. as will be discussed in a subsequent section, the unique entries constitute a significant proportion of the tags that represent ambiguous acronyms or abbreviated terms, such as ajax or psp. table 1. concepts represented by the tags delicious (%) furl (%) technorati (%) things 76 82 90.0 materials 0 0 0.4 activities 12 10 4.0 events 0 0 0.0 properties 8 6 4.0

grammatical forms of terms: ■ nouns and noun phrases ■ verbal nouns ■ noun phrases ■ premodified noun phrases ■ postmodified noun phrases ■ adjectives ■ adverbs table 2 shows the distribution of the grammatical forms of tags. if all the types of nouns are combined, then 95 percent of delicious tags, 94 percent of furl tags, and 97 percent of technorati tags constitute types of nouns. the gram­ matical structure of the tags in the three folksonomy sites thus reflects very closely the niso recommendations that tags consist of mainly nouns, with the added proviso that adjectives and adverbs be kept to a minimum. none of the folksonomy sites used adverbs as tags, and the num­ ber of adjectives was very small, forming an average total of 5 percent of the tags. nouns (plural and singular forms) niso divides nouns into two categories: count nouns (how many?), and noncount, or mass nouns (how much?). niso recommends that count nouns appear in the plural form and mass nouns in the singular form. niso specifies other types of nouns that appear typi­ cally in the singular form: ■ abstract concepts ■ beliefs; for example, judaism, taoism ■ activities; for example, digestion, distribution ■ emotions; for example, anger, envy, love, pity ■ properties; for example, conductivity, silence ■ disciplines; for example, chemistry, astronomy ■ unique entities table 3 shows the distribution of the singular and plu­ ral forms of noun tags. the term singular nouns was used to collocate all the types of non­plural nouns. table 3 represents the number of tags that constitute count nouns; this does not mean, however, that the tags appeared correctly in the plural form. of the count nouns, 36 percent of delicious tags, 62 percent of furl tags, and 34 percent of technorati tags appeared correctly in the plural form. it should be noted that although table 3 indicates that properties constitute 8 percent of delicious, 6 percent of furl, and 4 percent of technorati tags, most of these tags are adjectives, and thus are not counted in the table. the niso guidelines do not suggest the typical distribution of count versus singular nouns, but table 3 indicates that at least among the three folksonomy sites, singular nouns form the bulk of the tags. table 2. grammatical form of tags delicious (%) furl (%) technorati (%) nouns 88 71 86 verbal nouns 5 6 4 noun

technology and libraries | september 2007 spelling the niso guidelines divide the spelling of terms into two sections: warrant and authority. with respect to warrant, niso recommends that “the most widely accepted spell­ ing of words, based on warrant, should be adopted,” with cross­references made between variant spellings of terms. as far as authority is concerned, spelling should follow the practice of well­established dictionaries or glossaries. while spelling refers normally to whole words, i included in this analysis acronyms and abbreviations used to denote unique entities, such as countries or product names, as there are recognized spellings of such acronyms and abbreviations. table 4 shows the tags from the three sites that do not conform to recognized spelling; the terms in italics show the accepted spelling. the number of tags that do not conform to spelling warrant is clearly very few, constituting a total of 4 per­ cent of the delicious tags, 3 percent of the furl tags, and 2 percent of the technorati tags. two of the nonrecognized spellings in delicious are likely due to the difficulty of creating compound tags in this site, as was discussed earlier. the remainder of the tags conformed to recog­ nized spellings as found in the three reference sources consulted. the findings suggest that tags are spelled con­ sistently and in keeping with recognized warrant across the three folksonomy sites. because of the international nature of the three folksonomy sites, no default english spelling was assumed. table 5 shows those tags whose spellings reflect regional variations. none of the three folksonomy sites featured lexical variants of any one tag. as the three sites are united states–based, the preponderance of american spelling is not surprising. what is surprising, however, is that technorati features only the british variants in the total of tags examined in this study. it should be pointed out that the two lexical variants of these terms do appear in the three folksonomy sites; the two variants simply did not appear in the daily logs examined. no system to enable cross­referencing (for example, humour use or see humor) exists in any of the three folksonomy sites, nor is cross­referencing discussed in the help logs of the sites. abbreviations, initialisms, and acronyms niso recommends that the full form of terms should be used. abbreviations or acronyms should be used only when they are so well­established that the full form of the term is rarely used. cross­references should be made between the full and abbreviated forms of the terms. abbreviations and acronyms constitute 22 percent of delicious tags, 16 percent of furl tags, and 19 percent of technorati tags. the majority of these abbreviations and acronyms pertain to unique entities, such as product names (for example, flash, mac, and nfl). in the case of delicious and furl, none of the abbreviated tags is referred to also by its full form. four of the abbreviated technorati tags have full­form equivalents: ■ cheney/dick cheney ■ ie/internet explorer ■ sheehan/cindy sheehan ■ uae/united arab emirates abbreviations and acronyms play a significant role in the ambiguity of the tags from the three sites; they represent 71 percent of the abbreviated delicious tags, 45 percent of the abbreviated furl tags, and 73 percent of the abbreviated technorati tags. furl and technorati are very similar in the proportion of abbreviated tags used, but delicious is significantly higher. the delicious tags are focused more heavily upon computer­related products, which may explain why there are so many more abbrevi­ ated tags, as many of these products are often referred to by these shorter terms; for example, css, flash, apple, and so on. table 4. tags that

spiteri 21 neologisms, slang, and jargon the niso guidelines explain that neologisms, slang, and jargon terms are generally not included in standard dic­ tionaries and should be used only when there is no other widely accepted alternative. nonstandard tags do not constitute a particularly relevant proportion of the total number of tags per site; they account for 3 percent of the delicious tags, 10 percent of the furl tags, and 6 percent of the technorati tags. the nonstandard tags refer almost exclusively to either computer­ or sex­related concepts, such as podcast, wiki, and camsex. nonalphabetic characters this section of the niso guidelines deals with the use of capital letters and nonalphabetic characters. capitalization was not examined in the three folksonomy sites, as none of them are case sensitive; delicious and furl, for exam­ ple, post tags in lower case, regardless of whether the user has assigned upper or lower case, while technorati shows capital letters only if they are assigned by the users themselves. the niso guidelines state that nonalphabetic characters, such as hyphens, apostrophes (unless used for the possessive case), symbols, and punctuation marks, should not be used because they cause filing and search­ ing problems. table 6 shows the occurrence of nonalpha­ betic characters in the three folksonomy sites. a very small proportion of the tags in the three folk­ sonomy sites contains non­alphabetic characters, namely 1 percent of the delicious tags, and 3 percent of the furl and technorati tags. as was discussed previously, the delicious help screens may encourage people to use nonalphabetic characters to construct compound tags; in spite of this, however, such characters are not, in fact, used very frequently. it should be noted that the terms above were all searched, with punctuation intact, in their respective sites; in all three cases, the search engines retrieved the tags and their associated blogs or web sites, which suggests that nonalphabetic characters may not negatively impact searching. ■ discussion and recommendations the tags examined from the three folksonomy sites cor­ respond closely to a number of the niso guidelines pertaining to the structure of terms, namely in the types of concepts expressed by the tags, the predominance of single tags, the predominance of nouns, the use of recognized spelling, and the use of primarily alphabetic characters. potential problem areas in the structure of the tags pertain to the inconsistent use of the singular and plural form of count nouns, the difficulty with creating multi­ term tags in delicious, and the incidence of ambiguous tags in the form of homographs and unqualified abbre­ viations or acronyms. as has been seen, a significant proportion of tags that represent count nouns appears incorrectly in the singular form. because many search engines do not deploy default truncation, the use of the singular or plural form could affect retrieval; a search for the tag computer in delicious, for example, retrieved 208,409 hits, while one for computers retrieved 91,205 hits. some of the results from the two searches overlapped, but only if both the singular and plural forms of the tags coexist. it would thus be useful for the help features of the folksonomy sites to explain the difference between count and noncount nouns and to discuss the impact of the form of the noun upon retrieval. while all three sites conform to the niso recommendation that single terms be used whenever possible, some concepts cannot be expressed in this fashion, and thus folksonomy sites should accom­ modate the use of multiterm tags. table 6. nonalphabetic characters delicious (n=76) furl (n=208) technorati (n=229) hyphens — hollywood b-day; urlproject

use, but make no mention of this feature in their help screens, which means that such tags may be constructed inconsistently—for example, by the insertion of punctuation—where a sim­ ple space between the tags will suffice. as has been seen, delicious does not allow directly for the construction of multiterm tags, and in its instructions it actually promotes inconsistency in how various punctuation devices may be used to conflate two or three separate tags, once again at the detriment of retrieval, as is shown below: opensource: 103,476 hits open_source: 91, 205 hits open.source: 26,494 hits delicious should consider allowing for the insertion of spaces between the composite words of a compound tag; without this facility, users may be unaware of how to create compound tags. alternatively, delicious should recommend the use of only one punctuation symbol to conflate terms, such as the underscore. furl and technorati should explain clearly that compound tags may be formed by the simple convention of placing a space between the terms. ambiguous headings constitute the most problematic area in the construction of the tags; these headings take the form of homographs and abbreviations or acronyms. in the case of computer­related product names, it may be safe to assume that in the context of an online environ­ ment it is likely that the meaning of these product names is relatively self­evident. in the case of the tag yahoo, for example, none of the sites or blogs associated with this tag pertained to “a member of a race of brutes in swift’s gulliver’s travels who have the form and all the vices of humans, or a boorish, crass, or stupid person” (merriam­ webster 2007), but referred consistently to the internet service provider and search engine. on the other hand, the tag ajax was used to refer to asynchronous javascript and xml technology as well as to a number of mainly european soccer teams. given the international audience of these folksonomy sites, it may be unwise to assume that the meanings of these homographs are self­evident. library of congress subject headings often uses parenthetical qualifiers to clarify the meaning of terms— for example, python (computer program language)—even though this goes against niso recommendations. it is unlikely, however, that such use of parentheses will be effective in the folksonomy sites. a search for opera (browser), for example, will likely imply an underlying and boolean operator, which detracts from the pur­ pose and value of the parenthetical qualifier; this was confirmed in a furl search, where the terms opera and browser appeared either immediately adjacent to each other or within the same document. the application of the section of the niso guidelines pertaining to abbreviations and acronyms is particularly difficult, as it is important to balance between using abbre­ viated forms of concepts that are so well­known that the full version is hardly used versus creating ambiguous tags. the fact that abbreviated forms appear so prominently in the daily logs of the three folksonomy sites suggests that the full forms of these tags are, in fact, very well­established. at face value, therefore, many of the abbreviated tags are ambiguous because they can refer to different concepts, but it is questionable whether such tags as css, flash, apple, and rss, for example are, in fact, ambiguous to the users of the sites. the use of the full forms for these tags seems cumbersome, as these concepts are hardly ever referred to in their full form. it could possibly be argued, in fact, that in some cases, the full forms may not be familiar; i may know to what concept rss refers, for example, without knowing the specific words represented by the letters r, s, s. the possible ambiguity of abbreviated forms is com­ pounded by the fact that none of the three folkson­ omy sites allows for cross­references between equivalent terms, which is a standard feature of most controlled vocabularies, for example: nfl/national football league use national football league/used for nfl the help screens of the three sites do not address the notion of ambiguity in the construction of tags: they do not draw people’s attention to the inherent ambigu­ ity of abbreviated forms that may represent more than one concept. the sites also fail to address the fact that abbreviated forms (or any tag, for that matter) may be culturally based, so that while the meaning of nfl may be obvious to north american users, this may not be the case for people who live in other geographic areas. it may be useful for the folksonomy sites to add direct links to an online dictionary and to wikipedia, and to encourage people to use these sites to determine whether their cho­ sen tags may have more than one application or meaning; i had not realized, for example, that rss could represent twenty­three different concepts until i used wikipedia and was led to a disambiguation page. access to these external sources may help users decide which full version of the abbreviation to use in the case of ambiguity. the examination of the structure of the tags pointed to some deficiencies in section 6 of the niso guidelines, specifically its occasional lack of sufficient definition or explanation of some of its recommendations. the guidelines list seven types of concepts that are typically represented by controlled vocabulary terms, but rely only upon a few examples to define the meaning and scope of these concepts. the guidelines thus provide no consistent mechanism by which the creators of terms can assess consistently the types of concepts represented. how, for example, is a discipline to be determined? does the term business represent a discipline if it is a subject area that is taught formally in a post­secondary institute, for article title | author 23the structure and form of folksonomy tags | spiteri 23 example? is it necessary for a discipline to be recognized as such among a majority of educational institutions? in its examples for events, niso lists holidays and revolutions. it is unclear, however, what level of specificity applies to this concept; would christmas, for example, be considered an event or a unique entity/proper noun (which is listed separately from types of concepts)? it is only later in the guidelines, under the examples provided for unique enti­ ties (for example, fourth of july), that one may assume that a named event should be considered a unique entity. verbal nouns also are difficult to determine based only upon the niso examples, and once again no guidelines are provided to determine whether a noun represents an activity or a thing, or possibly both; for example, skiing or clipping. the lack of clear definitions in niso also appeared in the section pertaining to slang, neologisms, and jargon, which are considered to be nonstandard terms that do not generally appear in dictionaries. as was discussed previ­ ously, it is not clear at what point a jargon term or a slang term becomes a neologism. all of the slang tags found in the three sites (for example, babe) appeared in merriam­ webster, which may serve to make this niso section even more ambiguous. ■ conclusion the most notable suggested weaknesses of folksonomies are their potential for ambiguity, polysemy, synonymy, and basic level variation as well as the lack of consistent guidelines for the choice and form of tags. the examina­ tion of the tags of the three folksonomy sites in light of the niso guidelines suggests that ambiguity and polysemy (such as homographs) are indeed problems in the struc­ ture of the folksonomy tags, although the actual propor­ tion of homographs and ambiguous tags each constitutes fewer than one­quarter of the tags in each of the three folksonony sites. in other words, although ambiguity and polysemy are certainly problematic areas, most of the tags in each of the three sites are unambiguous in their meaning and thus conform to niso recommendations. the help sites of the three folksonomy provide few tangible guidelines for (1) the construction of tags, which affects the construction of multiterm tags; and (2) the clear distinction between the singular and plural forms of count versus noncount nouns. as has been shown, the use of the singular or plural forms of terms, as well as the use of punctuation to form multiterm tags, affects search results. a large proportion of the tags in all three sites consists of single terms, which mitigates the impact on retrieval, but the inconsistent use of the singular and plural forms of nouns is indeed significant and thus may have marked effect upon retrieval. synonymy and basic level variation were not examined in this study, but are certainly worthy of further exploration. in other areas, the tags conform closely to the niso guidelines for the choice and form of controlled vocabu­ laries. the tags represent mostly nouns, with very few unqualified adjectives or adverbs. the tags represent the types of concepts recommended by niso and conform well to recognized standards of spelling. most of the tags conform to standard usage; there are few instances of nonstandard usage, such as slang or jargon. in short, the structure of the tags in all three sites is well within the standards established and recognized for the construction of controlled vocabularies. should library catalogs decide to incorporate folkson­ omies, they should consider creating clearly written rec­ ommendations for the choice and form of tags that could include the following areas: ■ the difference between count and noncount nouns, as well as an explanation of how the use of the sin­ gular and plural forms affects retrieval. ■ one standard way in which to construct multiterm tags; for example, the insertion of a space between the component terms, or the use of an underscore between the terms. ■ a link to a recognized online dictionary and to wikipedia to enable users to determine the meanings of terms, to disambiguate amongst homographs, and to determine if the full form would be preferable to the abbreviated form. an explanation of the impact of ambiguous tags and homographs upon retrieval would be useful. ■ an acceptable use policy that would cover areas of potential concern, such as the use of potentially offensive tags, overly graphic tags, and so forth. although such terms were not the focus of this study, their presence was certainly evident in some cases, and would need to be considered in an environment that includes clients of all ages. with the use of such expanded guidelines and links to useful external reference sources, folksonomies could serve as a very powerful and flexible tool for increasing the user­friendliness and interactivity of public library catalogs, and also may be useful for encouraging other activities, such as informal online communities of readers and user­driven readers’ advisory services. works cited bateman, s., c. brooks, and g. mccalla. 2006. collaborative tagging approaches for ontological metadata in adaptive e-learning systems.

recommended by many digitization best practices in texas. for software, we had all the important basics such as ocr and image editing software for the project to start. for the following several months, i did extensive research on what digital asset management platform would be the best solution for the law library. we had options to continue displaying the digital collections through webpages or use a digital asset management platform that would provide long-term preservation as well as retrieval functions. we made the decision to go with the latter. generally speaking, there are two types of digital asset management platforms: proprietary and open source. in some rare occasions, a library chooses to develop its own system and not to use either type of the platforms if the library has designated programmers. there are pros and cons to both proprietary and open source platforms. although setting up the repository is fairly quick and easy on a proprietary platform, it can be very expensive to pay annual fees for hosting and using the service. for the open source software, it may appear to be “free” up front; however, installing and customizing the repository can be very time consuming and these solutions often lack technical and development support. there is no uniform rule for choosing a platform. it depends on what the organization wants to achieve and its own unique circumstances. i explored several popular proprietary platforms such as contentdm and digital commons. contentdm is an oclc product, which has a lot of capability and is especially good for displaying image collections. digital commons is owned of the repository is ongoing; it is valuable to share the experience with other institutions who wish to set up an institutional repository of their own and also add to the knowledgebase of ir development. institutional repository from the ground up unlike most large university libraries, law school libraries are usually behind on digital initiative activities because of smaller budgets, lack of staff, and fewer resources. although institutional repositories have already become a trend for large university libraries, it still appears to be a new concept for many law school libraries. at the beginning of 2009, i was hired as the digital information management librarian to develop a digital repository for the law school library. when i arrived at texas tech university law library, there was no institutional repository implemented. there were very few digital projects done at the law library. one digital collection was of faculty scholarship. this collection was displayed on a webpage with links to pdf files. another digital project, to digitize and provide access to the texas governor executive orders found in the texas register, was planned then disbanded because of the previous employee leaving the position. i started by looking at the digitization equipment in the library. the equipment was very limited: a very old and rarely used book scanner and a sheet-fed scanner. the good thing was that the library did have extra pcs to serve as workstations. i did research on the book scanner we had and also consulted colleagues i met at various digital library conferences about it. because the model is very outdated and has been discontinued by the vendor and thus had little value to our digitization project, i decided to get rid of the scanner. i then proposed to purchase an epson perfection building an open source institutional repository at a small law school library: is it realistic or unattainable? digital preservation activities among law libraries have largely been limited by a lack of funding, staffing and expertise. most law school libraries that have already implemented an institutional repository (ir) chose proprietary platforms because they are easy to set up, customize, and maintain with the technical and development support they provide. the texas tech university school of law digital repository is one of the few law school repositories in the nation that is built on the dspace open source platform.1 the repository is the law school’s first institutional repository in history. it was designed to collect, preserve, share and promote the law school’s digital materials, including research and scholarship of the law faculty and students, institutional history, and law-related resources. in addition, the repository also serves as a dark archive to house internal records. i n this article, the author describes the process of building the digital repository from scratch including hardware and software, customization, collection development, marketing and outreach, and future projects. although the development fang wang (fang.wang@ttu.edu) is digital information management librarian, texas tech university school of law library, lubbock, texas. 82 information technology and libraries | june 2011 two months later, we discovered that a preconfigured application called jumpbox for dspace was released and approved to be a much easier solution for the installation. the price was reasonable too, $149 a year (the price has jumped quite a bit since then). however, using jumpbox would leave our newly purchased red hat linux server of no use because jumpbox runs on ubuntu, therefore after some discussion we decided not to pursue it. we were a little stuck in the installation process. outsourcing the installation seemed to be a feasible solution for us at this point. we identified a reputable dspace service provider after doing extensive research including comparing vendors, obtaining references, and pursuing other avenues. after obtaining a quote, we were quite satisfied with the price and decided to contract with the vendor. while waiting for the contract to be approved by the university contracting office, i began designing the look and feel that is unique to the ttu school of law with some help from another library staff member. the installation finally took place at the beginning of january 2010. i worked very closely with the service provider during the installation to ensure the desired configuration for our dspace instance. our repository site with the ttu law branding became accessible to the public three days later. and with several weeks of warranty, we were able to adjust several configurations including display thumbnails for images. overall, we are very pleased with the results. after the installation, our it department maintains the dspace site and we host all the content on our own server. collection development of the ir content is the most critical element to an institutional repository. while we were waiting for our it department 66, the majority of the repositories worldwide were created using the dspace platform.2 for the installation, we looked at the opportunity to use services provided by the state digital library consortium texas digital library (tdl) and tried to pursue a partnership with the main university library, which had already implemented a digital repository. however, because of financial reasons and separate budgets, those approaches did not work out. so we decided to have our own it department install dspace. installation and customization of our dspace unlike large university libraries, smaller special libraries face many challenges while trying to establish an open source repository. after making the decision to use dspace, the first challenge we faced was the installation. dspace runs on postgresql or oracle and requires a server installation. customizing the web interface requires either the jspui (javaserver pages user interface) or xmlui (extensible markup language user interface). the staff in our it department knew little about dspace. however, another special library on campus offered their installation notes to our system administrator because they just installed dspace. although dspace runs on a variety of operating systems, we purchased red hat enterprise linux after some testing because it is the recommended os for dspace. then our system administrator spent several months trying to figure out how to install the software in addition to his existing projects. because we did not have dedicated it personnel working on the installation, the work was often interrupted and very difficult to complete. our it staff also found it very difficult to continue with the installation because the software requires a lot of expertise. by berkley press and is often used in the law library community. as a smaller law library, our budget did not allow us to purchase those platforms, which require annual fees of more than $10,000. so we had to look at the open source options. for the open source platforms, i investigated dspace, fedora, eprints and green stone. dspace is a javabased system developed by mit and hp labs. it offers a communitiescollections model and has built-in submission workflows and long-term preservation function. it can be installed “out of the box” and is easy to use. it has been widely adopted as institutional repository software in the united states and worldwide. fedora was also developed in the united states. it is more of a backend software with no web-based administration tools and requires a lot of programming effort. similar to dspace, eprints is another easy to set up and use ir software developed in the u.k. it is written in perl and is more widespread in europe. greenstone is a tool developed in new zealand for building and distributing digital library collections. it provides interfaces in 35 languages so it has many international users. when choosing an ir platform, it is not a question of which software is superior to others but rather which is more appropriate for the purpose and the content of the repository. our goal was to find a platform that had low costs and did not involve much programming. we also wanted a system that was capable of archiving digital items in various formats for the long term, flexible for data migration, had a widely accepted metadata scheme, decent search capability, and was easy to use. another factor we had to consider was the user base. because open source software relies on the user themselves for technical support for the most part, we wanted a software that had an active user community in the united states. dspace seemed to satisfy all of our needs. also, according to repository : | wang 83building an open source institutional repository at a small law school library | wang 83 hosted by the lubbock county bar association at the ttu law school. we made the initial announcement to the law faculty and staff and later to the lubbock county bar about the new digital initiative service we have established. we received very positive feedback from the law community. professor edgar’s family was delighted to see his collection made available to the public. following the success of the initial launch, i developed an outreach plan to promote the digital repository. to make the repository site more visible, several efforts were made: the repository site url was submitted to the dspace user registry, the directory of open access repositories (opendoar), and registry of open access repositories (roar); the site was registered with google webmaster tools for better indexing; and the repository was linked to several websites of the law school and library. the “faculty scholarship” collection and the “texas governor executive orders” collection became available shortly after. i then developed a poster of the newly established digital repository and presented it at the texas conference on digital libraries held at university of texas austin in may 2010. currently, our digital repository has more than eight hundred digital items as of august 2010. with more and more content becoming available in the repository, we plan on making an official announcement to the law community. we will also make entering first-year law students aware of the ir by including an article about the new repository in the library newsletter that is distributed to them during their orientation. our future marketing plan includes sending out announcements of new collections to the law school using our online announcement system techlawannounce and promoting the digital repository through the law library social networking pages on facebook and twitter. we also plan reviewed each year. based on the collection development policy, we made a decision to migrate the content of the old “faculty scholarship” collection from webpages into the digital repository. it was intended to include all publications of the texas tech law school faculty in the collection. we then hired a second-year law student as the digital project assistant and trained him on scanning, editing, and ocr-ing pdf files; uploading files to dspace; and creating basic metadata. we also brought another two student assistants on board to help with the migration of the faculty scholarship collection. the faculty services librarian checked the copyright with faculty members and publishers while i (the digital information management librarian) served as the repository manager handling more complicated metadata creation, performing quality control over student submissions, and overseeing the whole project. later development and promoting the ir during the faculty scholarship migration process, we discovered a need to customize dspace to allow active urls for publications. we wanted all the articles linked to three widely used legal databases: westlaw, lexisnexis, and hein online. because the default dspace system does not support active urls, it requires some programming effort to make the system detect a particular metadata field then render it as a clickable link. we outsourced the development to the same service provider who installed dspace for us. the results were very satisfying. the vendor customized the system to allow active urls and displayed the links as clickable icons for each legal database. in april 2010, “professor j. hadley edgar ’s personal papers” collection was made available in conjunction with his memorial service, to install dspace, we prepared and scanned two collections: the “texas governor executive orders” collection and the “professor j. hadley edgar’s personal papers” collection. the latter was a collection donated by professor edgar’s wife after he passed away in 2009. professor edgar taught at the law school from 1971 to 1991. he was named the robert h. bean professor of law and was twice voted by the student body as the outstanding law professor. the collection contains personal correspondence, photos, newspaper clippings, certificates, and other materials. many of the items have a high historic value to the law school. for the scanning standards, we used 200 dpi for text-based materials and 400 dpi for pictures. we chose pdf as our production file format as it is a common document format and smaller in size to download. after the installation was completed at the beginning of january, i drafted and implemented a digital repository collection development policy shortly after to ensure proper procedures and guidance of the repository development. the policy includes elements such as the purpose of the repository, scope of the collections, selection criteria and responsibilities, editorial rights, and how to handle challenges and withdrawals. i also developed a repository release form to obtain permissions from donors and authors to ensure open access for the materials in the repository. twelve collections were initially planned for the repository: “faculty scholarship,” “personal manuscripts,” “texas governor executive orders,” “law school history,” “law library history,” “regional legal history,” “law student works,” “audio/ video collection,” “dark archive,” “electronic journals,” “conference, colloquium and symposium,” and “lectures and presentations.” there will be changes to the collections in the future as the digital repository collection development policy will be 84 information technology and libraries | june 2011 all roads lead to rome. no matter what platform you choose, whether open source or not, the goal is to pick a system that best suits your organization’s needs. to build a successful institutional repository is not simply “scanning” and “putting stuff online.” various factors need to be considered, such as digitization, ir platform, collection development, metadata, copyright issues, and marketing and outreach. our experience has proven that it is possible for a smaller special library with limited resources and funding to establish an open source ir such as dspace and continue to maintain the site and build the collections with success. open source software is certainly not “free” because it requires a lot of effort. however, in the end it still costs a lot less than what we would pay to the proprietary software vendors. references 1. “the texas tech university school of law digital repository,” http://reposi

some development on the dspace authentication to integrate with the ttu “eraider” system to enable single log-in. in the future, we want to explore the possibilities of setting up a collection for the works of our law students and engage in electronic journal publishing using our digital repository. conclusion it is not an easy task to develop an institutional repository from scratch, especially for a smaller organization. installation and development are certainly a big challenge for a smaller library with limited number of it staff. outsourcing these needs to a service provider seems to be a feasible solution. another challenge is training. we overcame this challenge by taking advantage of the state consortium’s dspace training sessions. subscribing to the dspace mailing list is necessary as it is a communication channel for dspace users to ask questions, seek help, and keep up to date about the software. on hosting information sessions for our law faculty and students to learn more about the digital repository. future projects there is no doubt that our digital repository will grow significantly because we have exciting collections planned for future projects. one of our law faculty, professor daniel benson, donated some of his personal files from an eight-year litigation representing the minority plaintiffs in the civil rights case of jones v. city of lubbock, 727 f. 2d 364 (5th cir. 1984) in which the minority plaintiffs won the case. the lawsuit changed the city of lubbock’s election system for city council members from the “at large” method to the “single member district system,” which allowed the minority candidates consistently being elected. this collection contains materials, notes, memoranda, letters, and other documents prepared and utilized by the plaintiffs’ attorneys. it has significant historical value because a texas tech law professor and five texas tech law graduates participated in that case successfully as pro bono attorneys for the minority plaintiffs. in addition, we plan on adding social science research network automated storage & retrieval system: from storage to service articles automated storage & retrieval system: from storage to service justin kovalcik and mike villalobos information technology and libraries | december 2019 114 justin kovalcik (jdkovalcik@gmail.com) is director of library information technology, csun oviatt library. mike villalobos (mike.villalobos@csun.edu) is guest services supervisor, csun oviatt library. abstract the california state university, northridge (csun) oviatt library was the first library in the world to integrate an automated storage and retrieval system (as/rs) into its operations. the as/rs continues to provide efficient space management for the library. however, added value has been identified in materials security and inventory as well as customer service. the concept of library as space, paired with improved services and efficiencies, has resulted in the as/rs becoming a critical component of library operations and future strategy. staffing, service, and security opportunities paired with support and maintenance challenges, enable the library to provide a unique critique and assessment of an as/rs. introduction “space is a premium” is a phrase not unique to libraries; however, due to the inclusive and open environment promoted by libraries, their floor space is especially attractive to those within and outside of the building’s traditional walls. in many libraries, the majority of floor space is used to house a library’s collection. in the past, as collections grew, floor space became increasingly limited. faced with expanding expectations and demands, libraries struggled to identify a balance between transforming space for new services while adding materials to a growing collection. in addition to management activities like weeding, other solutions such as offsite storage and compact shelving rose in popularity as a method to create library space in the absence o f new building construction. years later as collections move away from print and physical materials, libraries are beginning to reexamine their building’s space and envision new features and services. “now that so many library holdings are accessible digitally, academic libraries have the opportunity to make use of their physical space in new and innovative ways.”1 the csun oviatt library took a novel approach and launched the world’s first automated storage and retrieval system (as/rs) in 1991 as a storage solution to resolve its building space limitations. the project was a california state university (csu) system chancellor’s office initiative that cost more than $2 million to implement and began in 1989. the original concept “came from the warehousing industry, where it had been used by business enterprises for years.”2 by leveraging and storing physical materials in the as/rs, the csun oviatt library is able to create space within the library for new activities and services. “instead of simply storing information materials, the library space can and should evolve to meet current academic needs by transforming into an environment that encourages collaborative work.”3 mailto:jdkovalcik@gmail.com mailto:mike.villalobos@csun.edu automated storage & retrieval system | kovalcik and villalobos 115 https://doi.org/10.6017/ital.v38i4.11273 unfortunately, as the first stewards of an as/rs, csun made decisions that led to mismanagement and neglect resulting in the as/rs facing many challenges in becoming a stable and reliable component of the library. however, recent efforts have sought to resolve these issues and resulted in system updates, management, and functionality. whereas in the past low-use materials were placed in as/rs to create space for new materials, now materials are moved into the as/rs to create space for patrons, secure collections, and improve customer service. as part of this critical review, the functionality and maintenance along with the historical and current management of the as/rs will be examined. background csun is the second-largest member of the twenty-three-campus csu system. the diverse university community includes over 38,000 students and more than 4,000 employees.4 consisting of nine colleges offering 60 baccalaureate degrees, 41 master’s degrees, 28 credentials in education, and various extended learning and special programs, csun provides a diverse community with numerous opportunities for scholarly success.5 the csun oviatt library’s as/rs is an imposing and impressive area of the library that routinely attracts onlookers and has become part of the campus tour. the as/rs is housed in the library’s east wing and occupies an area that is 8,000 square feet and 40 feet high arranged into six aisles. the 13,260 steel bins, each 2 feet x 4 feet, in heights of 6, 10, 12, 15, and 18 inches, are stored on both sides of the aisles enabling the as/rs to store an estimated 1.2 million items.6 each aisle has a storage retrieval machine (srm) that performs automatic, semiautomatic, and manual “picks” and “deposits” of the bins.7 the as/rs was assessed in 2014 as responsibilities, support, and expectations of the system shifted and previous configurations were no longer viable. discontinued and failing equipment, unsupported server software, inconsistent training and use, and decreased local support and management were identified as impediments for greater involvement in library projects and operations. campus provided funding in 2015 to update the server software as well as major hardware components on three of the six aisles. divided into two phases, the server software upgrade was completed in may 2017 followed by the hardware upgrade in january 2019.8 literature review the continued growth of student, faculty, and academic programs along with evolving expectations and needs since the late 1980s has required the library to analyze library services and examine the building’s physical space and storage capacity. in the late 1980s, identifying space for increasing printed materials was the main contributing factor in implementing the as/rs. in the mid-2010s, creating space within the library for new services was dependent on a stable and reliable as/rs. “the conventional way of solving the space problem by adding new buildings and off-site storage facilities was untenable.”9 a benefit of an as/rs, as creaghe and davis predicted in 1986 was, “the probable slow transition from books to electronic media, an aaf [automated access facility] may postpone the need for future library construction indefinitely.”10 the as/rs has enabled the library to create space by removing physical materials while enhancing customer service, material security, and inventory control. “the role of the library as service has been evolving in lockstep with user needs. the current transformative process that takes place in academia has a powerful impact on at least two functional areas of the library: information technology and libraries | december 2019 116 library as space and library as collection.”11 in addition, the “increased security the aaf … offers will save patrons time that would be spent looking for books on the open shelves that may be in use in the library, on the waiting shelves, misplaced, or missing.”12 in subsequent years, library services have evolved to include computer labs with multiple high-use printers/scanners/copiers, instructional spaces, individual and group study spaces, makerspaces, etc., in addition to campus entities that have required large amounts of physical space within the library. “it is well-known that academic libraries have storage problems. traditional remedies for this situation—used in libraries across the nation—include off-site storage for less used volumes, as well as, more recently, innovative compact shelving. these solutions help, but each has its disadvantages, and both are far from ideal. . . . when the eastern michigan university library had the opportunity to move into a new building, we saw that an as/rs system would enable us to gain open space for activities such as computer labs, training rooms, a cafe, meeting rooms, and seating for students studying.”13 the as/rs provides all the space advantages provided by off-site storage and compact shelving while adding much more value while mitigating negatives of off-site time delays and the confusion of accessing and using compact shelving. staffing & usage 1991–1994 following the 80/20 principle, low-use items were initially selected for storage in the as/rs. “when the storage policy was being developed in [the] 1990s, the 80/20 principle was firmly espoused by librarians. . . . thus, by moving lower-use materials to as/rs, the library could still ensure that more than 80% of the use of the materials occurs on volumes available in the open stacks.”14 low-use items were identified if one of the following three conditions was met: (1) the item’s last circulation date was more than five years ago; (2) the item was a non-circulating periodical; or (3) items that were not designed to leave an area and received little patron usage such as the reference collection. in 1991, the as/rs was loaded with 800,000 low-use items and went live for the first time later that year. staffing for the initial as/rs department consisted of one full-time as/rs supervisor (40 hours/week), one part-time as/rs repair technician (20 hours/week), and 40 hours a week of dedicated student employees, for a total of 100 hours a week of dedicated as/rs management. the as/rs was largely utilized as a specialized service for internal library operations with limited patron-initiated requests. as/rs operations were uniquely created and customized for each as/rs operator as well as the desired task needing to be performed. skills were developed internally with knowledge and training shared by word of mouth or accompanied with limited documentation. 2000 mid-2000s the as/rs department functioned in this manner until the 1994 northridge earthquake struck the campus directly and required partial building reconstruction to the library. although there was no damage to the as/rs itself or its surrounding structure, extensive damage occurred in the wings of the library. the damage resulted in the library building being closed and inaccessible. when the library reopened in 2000, it was determined that due to previous as/rs low usage that a dedicated department was no longer warranted. the as/rs supervisor position was dissolved, the student employee budget was eliminated, and the as/rs technician position was not replaced after the employee retired in 2008. as/rs operational responsibilities were consolidated into the circulation department and as/rs administration into the systems department. both circulation automated storage & retrieval system | kovalcik and villalobos 117 https://doi.org/10.6017/ital.v38i4.11273 and systems departments redefined their roles and responsibilities to include the as/rs without additional budgetary funding, staffing, or training. in order for as/rs operations to be absorbed by these departments, changes had to occur in the administration, operating procedures, staffing assignments, and access to the as/rs. all five circulation staff members and twenty student employees received informal training by members of the former as/rs department in the daily operations of the as/rs. the circulation members also received additional training for first-tier troubleshooting of as/rs operations such as bin alignments, emergency stops, and inventory audits. the as/rs repair technician remained in the systems department; however, as/rs troubleshooting responsibility was shared among the systems support specialists and dedicated as/rs support was lost. the administrative tasks of scheduling preventive maintenance services (pms), resolving as/rs hardware/equipment issues with the vendor, and maintaining the server software remained with the head of the systems department. without a dedicated department providing oversight for the as/rs, issues and problems began to occur frequently. circulation had neither the training nor resources available to master procedures or enforce quality control measures. similarly, the systems department became increasingly removed from daily operations. many issues were not reported at all and became viewed as system quirks that required workarounds or were viewed as limitations of the system. for issues that were reported, troubleshooting had to start all over again and systems relied on circulation staff being able to replicate the issue in order to demonstrate the problem. system’s personnel retained little knowledge on performing daily operations, and troubleshooting became more complex and problematic as different operators had different levels of knowledge and skill that accompanied their unique procedures. mid-2000s–2015 these issues became further exasperated when areas outside of circulation were given full access to the as/rs in the mid-2000s. employees from different departments of the library began entering and accessing the as/rs area and operated the as/rs based on knowledge and skills they learned informally. student assistants from these other departments also began accessing the area and performing tasks on behalf of their informally trained supervisors. further, without access control, employees as well as students ventured into the “pit” area of the as/rs where the srms move and end-of-aisle operations occur. this area contains many hazards and is unsafe without proper training. during this period, the special collections and archives (sc/a) department loaded thousands of un-cataloged, high-use items into the as/rs that required specialized service from circulation. these items were categorized as “non-library of congress” and inventory records were entered into the as/rs software manually by various library employees. in addition, paper copies were created and maintained as an independent inventory by sc/a. over the years, the sc/a paper inventory copies were found to be insufficiently labeled, misidentified, or missing. therefore, the as/rs software inventory database and the sc/a paper copy inventory contained conflicts that could not be reconciled. to resolve this situation, an audit of sc/a materials was completed in spring 2019 to locate inventory that was thought to be missing. information technology and libraries | december 2019 118 all bound journals and current periodicals were eventually loaded into the as/rs as well, causing other departments and areas to rely on the as/rs more heavily. departments such as interlibrary loan and reserves, as well as patrons, began requesting materials stored in the as/rs more routinely and frequently. the as/rs transformed from a storage space with limited usage to an active area with simultaneous usage requests of different types throughout the day. without a dedicated staff to organize, troubleshoot, and provide quality control, there was an abundance of errors that led to long waits for materials, interdepartmental conflicts, and unresolved errors. high-use materials from sc/a, as well as currently received periodicals from the main collection, were the catalysts that drove and eventually warranted change in the as/rs usage model from storage to service. the inclusion of these materials created new primary customers identified as internal library departments: sc/a and interlibrary loan (ill). with over 4,000 materials contained in the as/rs, sc/a requires prompt service for processing archival material into the as/rs and filling specialized patron requests for these materials. in addition, ill processes over 500 periodical requests per month that utilize and depended on as/rs services. the additional storage and requests created an uptick in overall as/rs utilization that carried over into circulation desk operations as well. 2015–present the move from storage to service was not only inevitable due to an evolving as/rs inventory, but was necessary in order to regain quality control and manage the library-wide projects that involved the as/rs. the increased usage and reliance on the as/rs required the system be well maintained and managed. administration of the as/rs remains within systems and circulation student employees continue to provide supervised assistance to the as/rs. the crucial change was identified and emerged within circulation for a dedicated operations and project manager. an as/rs lead position was created with responsibilities for the daily operations and management of the system and service. however, this was not a complete return to the original staffing concept of the early 1990s. the concept for this new position focuses on project management and system operations rather than the original sole attention to system operations. the as/rs lead is the point of contact for all library projects that utilize the as/rs, relaying any as/rs issues or concerns to systems, and daily as/rs usage. this shift is necessary due to the increased demand and reliance on the system that has changed its charge from storage to service. customer service the library noted over time that the as/rs could be used as a tool in weeding and other collection shift projects to create space and aid in reorganizing materials. as more high-use materials were loaded into the as/rs the indirect advantages of the as/rs became more apparent. patrons request materials stored within the as/rs through the library’s website and pick up the materials at the circulation desk. there is no need for patrons to navigate the library, successfully use the classification system, and search shelves to locate an item that may or may not be there. as kirsch notes, “the ability to request items electronically and pick them up within minutes eliminates the user’s frustration at searching the aisles and floors of an unfamiliar library.”15 the vast majority of library patrons are csun students that commute and must make the best use of their time while on campus. housing items in the as/rs creates the opportunity to have hundreds of thousands of items all picked up and returned to one central location. this makes it far easier for library patrons, especially users with mobility challenges, to engage with a plethora of library automated storage & retrieval system | kovalcik and villalobos 119 https://doi.org/10.6017/ital.v38i4.11273 materials. the time allotted for library research and/or enjoyment becomes more productive as their desired materials are delivered within minutes of arriving in the building. as heinrich and willis state, “the provision of the nimble, just-in-time collection becomes paramount, and the demand for as/rs increases exponentially.”16 as/rs items are more readily available than shelved items on the floor, as it takes minutes to have as/rs items returned and made available once again. “they may be lost, stolen, misshelved, or simply still on their way back to the shelves from circulation—we actually have no way of knowing where they are without a lengthy manual search process, which may take days. . . . unlike books on the open shelves, returned storage books are immediately and easily ‘reshelved’ and quickly available again.”17 another advantage is there is no need to keep materials in call-number order with the unpleasant reality of missing and misshelved items. items in the as/rs are assigned bin locations that can only be accessed by an operatoror user-initiated request. the workflow required to remove a material from the as/rs involves multiple scans and procedures that increase accountability that does not exist for items stored on floor shelves. further, users are assured of an item’s availability within the system. storing materials in the as/rs ensures that items are always checked out when they leave the library and not sitting unaccounted for in library offices and processing areas. it also avoids patron frustration of misshelved, recently checked-out, or missing items. security the decision to follow the 80/20 principle and place low-use items in the as/rs meant high-use items remained freely available to library patrons on the open shelves of each floor. this resulted in high-use items being available for patron browsing and checkout, as well as patron misuse and theft. the sole means of securing these high-use items involved tattle-tape and installing security gates at the main entrance. therefore, the development of policies and procedures for the enforcement of these gates was also required. beyond the inherent cost, maintenance, and issue of ensuring items are sensitized and desensitized correctly, gate enforcement became another issue that rested upon the circulation department. assuming theft would occur by exiting the building through passing through the gates at the main entrance of the library, enforcement is limited in actions that may be performed by library employees. touching, impeding the path, following, detaining, searching, etc. of library patrons are restricted actions reserved for campus authorities such as the police and not library employees. rather than attempting to enforce a security mechanism in which we have no authority, the as/rs provides an alternative for the security of high-use and valuable materials. storing items in the as/rs eliminates the possibility of theft or damage by visitors and places control and accountability over the internal use of materials. “there would be far fewer instances of mutilation and fewer missing items.”18 further, access to the as/rs area was restricted from all library personnel to only circulation and systems employees with limited exceptions. individual log ins also provided a method of control and accountability as each operator is required to use a personal account rather than a departmental account to perform actions on the as/rs. materials stored in the as/rs are, “more significantly . . . safer from theft and vandalism.”19 information technology and libraries | december 2019 120 inventory conducting a full inventory of a library collection is time consuming, expensive, and often inaccurate by the time of completion. missing or lost items, shelf reading projects, in-process items, etc. create overhead for library employees and generate frustration for patrons searching for an item. massive, library-wide projects such as collection shifts and weeding are common endeavors undertaken to create space, remove outdated materials, and improve collection efficiency. however, actions taken on an open shelves collection is time consuming, costly, inefficient, and affect patron activities. these projects typically involve months of work that involve multiple departments to complete. items stored within the as/rs do not experience these challenges because the system is managed by a full-time employee throughout the year and not on a project basis. the system is capable of performing inventory audits, and does not affect public services. therefore, while the cost of an item on an open shelf is $0.079, the cost of storing the same item in the as/rs is $0.0220 routine and spot audits ensure an accurate inventory, confirm capacity level of the system, and establish best management of the bins. as/rs inventory audits are highly accurate and much more efficient than shelf reading with little impact to patron services. “while this takes some staff time, it is far less time-consuming than shelf reading or searching for misshelved books.”21 storing materials in the as/rs is more efficient than on open shelves; however, bin management is essential in ensuring bins are configured in the best arrangement to achieve optimal efficiency. the size and configuration of bins directly affects storage capacity. type of storage, random or dedicated, also influences capacity, efficiency, and accessibility of items. the 13,260 steel bins in the as/rs range in height from 6 to 18 inches. the most commonly used bins are the 10and 12-inch bins; however, there is a finite number of these bin heights. unfortunately, the smallest and largest bins are rarely used due to material sizes and weight capacity; therefore, as/rs optimal capacity is unattainable and the number of materials eligible for loading limited by number of bins available. the library also determined that dedicated, rather than random, bin storage type aided in locating specialized materials, reduced loading and retrieval errors, and enhanced accessibility by arranging highly used bins to reachable locations. in the event an srm breaks down and an aisle becomes nonfunctional for retrieving bins, strategically placing the highest used and specialized locations in bins that can be manually pulled is a proactive strategy. however, this requires dedicated bins with an accurate and known inventory that has been arranged in accessible locations. lessons learned disasters & security in 1994, the as/rs proved to provide a much more stable and secure environment than the open stacks when it successfully endured a 6.9 earthquake. the reshelving of more than 300,000 items required a crew of more than thirty personnel over a year to complete. many items were destroyed from the impact of falling to the floor and being buried underneath hundreds of other automated storage & retrieval system | kovalcik and villalobos 121 https://doi.org/10.6017/ital.v38i4.11273 items. the as/rs in contrast consisted of over 800,000 items and successfully sustained the brunt of the earthquake’s impact with no damage to any of the stored items. unfortunately. the materials that had been loaded into the as/rs in 1991 were low-use items that were viewed as one step from weeding. therefore, high-use items stored in open shelves were damaged and required the long process of recovery and reconstruction: identifying and cataloging damaged and undamaged materials, disposal of those damaged, renovation of the area, and purchase of new items. the low-use items stored in the as/rs by contrast required a few bins that had slightly shifted be pushed back fully into their slots. as/rs items have proven to be more secure from misplacement, theft, and physical damage from earthquakes as compared to items in open shelves. maintenance, support, and modernization the csun oviatt library has received two major updates to the as/rs since it was installed in 1991. in 2011, the as/rs received updates for communication and positioning components. the second major update occurred in two phases between 2016 and 2018 and focused on software and equipment. in phase one, server and client-side software was updated from the original software created in 1989. in phase two, half the srms received new motors, drives, and controllers. due to the many years of reliance on preventive maintenance (pm) visits and avoidance of modernization, our vendors were unable to provide support for the as/rs software and had difficulty locating equipment that had become obsolete. preventive maintenance visits were used to maintain the status quo and are not a long-term strategy for maintaining a large investment and critical component of business operations. creaghe and davis note that, “current industrial facility managers report that with a proper aaf [automated access facility] maintenance program, it is realistic to expect the system to be up 9598 percent of the time.”22 pm service is essential for long-term as/rs success; however, preventive maintenance alone is incapable of modernization and ensuring equipment and software do not become obsolete. maintenance is not the same as support, rather maintenance is an aspect of support. support includes points of contacts who are available for troubleshooting, spare supplies on hand for quick repairs, a life-cycle strategy for major components, and longterm planning and budgeting. kirsch attested the following describing eastern michigan university’s strategy: “although the dean is proud and excited about this technology, he acknowledges that just like any computerized technology, when it’s down, it’s down. ” to avoid system problems, emu bought a twenty-year supply of major spare parts and employs the equivalent of one-and-a-half full-time workers to care for its automated storage and retrieval system.”23 a system that relies solely on preventive maintenance will quickly become obsolete and require large and expensive projects in the future if the system is to continue functioning. further, modernization provides an avenue for new features and functions to be realized that increase functionality and efficiency. networking the csun oviatt library on average receives between three to four visits a year along with multiple emails and phone conversations requesting information from different libraries regarding the as/rs. these conversations aid the library by viewing the as/rs in different perspectives and forces the library to review current practices. information technology and libraries | december 2019 122 the library has learned through speaking with many different libraries that needs, design, and configuration of an as/rs can be as unique as the libraries inquiring. the csun oviatt library, for example. is much different than the three other csu system libraries that have an as/rs. due to our system being outdated, it has been difficult to form or establish meaningful groups or share information because the systems are all different from each other. as more conversations occur and systems become more modern and standard, there is potential for knowledge sharing as well as group lobbying efforts for features and pricing. buy in user confidence in any system is required in order for that system to be successful. convincing a user base that moving materials from readily available open shelves and transferring them into steel bins housed within 40-feet-high aisles that are inaccessible will be difficult if the system is consistently down. therefore, the better the as/rs is managed and supported, the more reliable and dependable that system will be and the likelihood user confidence will grow. informing stakeholders of long-term planning and welcoming feedback demonstrates that the system is being supported and managed with an ongoing strategy that is part of future library operations. similarly, administrators need confirmation that large investments and mission-critical services are stable, reliable, and efficient. creating a new line item in the budget for as/rs support and equipment life-cycle requires justification along with a firm understanding of the system. in addition, staffing and organizational responsibilities must also be reviewed in order to establish an environment that is successful and efficient. continuous assessments of the as/rs regarding downtime, projects involved, services and efficiencies provided, etc. aid in providing an illustration of the importance and impact of the system on library operations as a whole. recording usage and statistics unfortunately, usage statistics were not recorded for the as/rs prior to june 2017. therefore, data is unavailable to analyze previous system usage, maintenance, downtime, or project involvement. data-driven decisions require the collection of statistics for system analysis and assessment. following the server software and hardware updates, efforts have been taken to record project statistics, inventory audits, and srm faults, as well as public and internal paging requests. conclusion the as/rs remains, as heinrich & willis described it, “a time-tested innovation.”24 through lessons learned and objective assessment, the library is positioning the as/rs to be a critical component for future development and strategy. by expanding the role of the as/rs to include functions beyond low-use storage, the library discovered efficiencies in material security, customer service, inventory accountability, and strategic planning. the csun oviatt library has learned, experienced, and adjusted its perception, treatment, and usage of the as/rs over the past thirty years. factors often forgotten such as access to the area, staffing and inventory auditing are easily overlooked, while other potential functions such as material security and customer services may not be identified without ongoing analysis and

50 years of ital/jla: a bibliometric study of its major influences, themes, and interdisplinarity brady lund information technology and libraries | june 2019 18 brady lund (blund2@g.emporia.edu) is a phd student at emporia state university’s school of library and information management. abstract over five decades, information technology and libraries (and its predecessor, the journal of library automation) has influenced research and practice in the library and information science technology. from its inception on, the journal has been consistently ranked as one of the superior publications in the profession and a trendsetter for all types of librarians and researchers. this research examines ital using a citation analysis of all 878 peer-reviewed feature articles published over the journal’s 51 volumes. impactful authors, articles, publications, and themes from the journal’s history are identified. the findings of this study provide insight into the history of ital and potential topics of interest to ital authors and readership. introduction fifty-one years have passed since the first publication of the journal of library automation (jla), the precursor to information technology and libraries (ital), in 1968: 51 volumes, 204 issues, and 878 feature articles. information technology and its use within libraries has evolved dramatically in the time since the first volume, as has the content of the journal itself. given the interdisciplinary nature of library and information science (lis) and ital, and the celebration of this momentous achievement, an examination of the journal’s evolution, based on the authors, publishers, and works that have influenced its content, seems apropos. the following article presents a comprehensive study of all 7,575 references listed for the 878 articles (~8.6 refs/article average) published over ital’s fifty years, identifying those authors and publishers whose work has been cited the most in the journal and major themes in the cited publications, and an evaluation of the interdisciplinarity of references in ital publications. this study not only frames the history of the ital journal, but demonstrates an evolution of the journal that suggests new paths for future inquiry. conceptual framework a major influence for the organization and methodology of this paper is imad al-sabbagh’s 1987 dissertation from florida state university’s school of library and information studies, the evolution of the interdisciplinarity of information science: a bibliometric study.1 in this study, alsabbagh sought to examine the interdisciplinary influences on the burgeoning field of information science by examining the references of the journal of the american society of information science (jasis), today known as the journal of the association for information science and technology (jasist). in al-sabbagh’s study, a sample of ten percent of jasis references was selected for examination.2 the references were sorted into disciplines based on the definitions supplied by information technology and libraries | june 2019 19 dewey decimal classification categories, with the percentages compared to the total number of the sampled references to derive percentages (e.g., if 150 references of 1,000 total jasis references examined belonged to the category of library science, then 15 percent of references belonged to library science, and so on for all disciplines). the present study deviates slightly from al-sabbagh’s in that it does not use a sampling method. instead, all 878 articles published in jla/ital and their 7,575 references will be examined. the categories for disciplines, instead of being based of dewey decimal, will be based on definitions derived from encyclopedia brittanica, and will include new disciplines that were not used in al-sabbagh’s original analysis, such as information systems and instructional design. 3 additionally, the major authors, publishers, and articles cited throughout jla/ital’s history will be identified; this was not done in al-sabbagh’s study, but will likely provide additional beneficial information for researchers and potential contributors to ital. ital is an ideal publication to study using al-sabbagh’s methodology, in that it is affiliated with librarianship and library science but, due to its content, is also closely associated with the disciplines of information science, computer science, information systems, instructional design, psychology, and many others. ital is likely one of the more interdisciplinary journals to still fall within the category of “library science.” in fact, as part of al-sabbagh’s 1987 study, he distributed a survey to several prominent information science researchers, asking them to name journals relevant to information science (this method was used to determine that jasis was the most representative journal for the discipline of information science). on the list of 31 journals compiled from the respondents’ rankings, ital ranked as the seventh most representative journal for information science, above datamation, scientometrics, jelis, and library hi-tech.4 this shows that, for a long time, ital has been considered as an important journal not just in library science, but in information science and likely beyond. key terminology while the findings of this study are pertinent to the ital reader, some of the terminology used throughout the study may be unfamiliar. to acclimate the reader to the terminology used in this study, brief definitions for key concepts are provided below. bibliometrics. “bibliometrics” is the statistical study of properties of documents.5 the present study constitutes a “citation analysis,” a type of bibliometric analysis that examines the citations in a document and what they can reveal about said document. cited publications. “cited publications” are the references (“publications”) listed at the end of a journal article.6 the purpose of al-sabbagh’s study (and the present study) is to analyze these cited publications to determine what disciplines influenced the research published in a specific journal. this bibliometric analysis methodology is distinct from those that examine the influence of a specific journal on a discipline (i.e., the present study looks at what disciplines influenced ital, not what disciplines are influenced by ital). discipline. in this study, the term “discipline” is used liberally to refer to any area of study that is presently or was historically offered at an institution of higher education (sociology, anthropology, education, etc.). in this study, library science and information science are considered as distinct disciplines (as was the case with al-sabbagh’s study).7 as discussed in the methodology section, the names and definitions of disciplines are all derived from the encyclopedia britanica. 50 years of ital/jla | lund 20 https://doi.org/10.6017/ital.v38i2.10875 literature review the type of citation analysis used by al-sabbagh and as the basis of the current study are used frequently to examine the interdisciplinarity of library and information science and specific lis journals, as noted by huang and chang.8 tsay used a similar methodology to al-sabbagh to examine cited publications in the 1980, 1985, 1990, 1995, 2000, and 2004 volumes of jasist. in this study, the researcher found that about one-half of the citations in jasist came from the field of lis.9 butler examined lis dissertations using a similar approach, finding that about 50 percent of the cited publications in the dissertations originated in lis, with education, computer science, and health science following in the second, third, and fourth positions.10 chikate and paul and chen and liang conducted similar studies of dissertations in the india and taiwan.11 each study found different degrees of interdisciplinarity, possibly indicating a fluctuation within the discipline of lis based on publication type, country of origin, etc. for the publications used in the study. several researchers have used these methods recently to examine library and information science journals, such as chinese librarianship,12 pakistan journal of library and information science,13 library philosophy and practice,14 and the journal of library and information technology.15 these studies are more common for journals published outside of the united states, but there is no reason why the methodology would not hold true for a u.s.-based journal like ital. recently, publications in a wide array of fields have used similar methodologies as al-sabbagh to evaluate interdisciplinarity in a discipline. ramos-rodriguez and ruiz-navarro (2004) examined reference trends in the journal of strategic management.16 fernandez-alles and ramos-rodriguez (2009) conducted a bibliometric analysis to identifying those publications most frequently cited in the journal human resource management.17 crawley-low (2006) used a similar methodology to identify the core (most frequently cited) journals in veterinary medicine from the american journal of veterinary research.18 these studies show a growing interest in the use of citation analysis to present new information about a publication to potential authors, editors, and readers. jarvelin and vakkari (1993) noted trends in lis from 1965 to 1985 based on an examination of cited publications in lis journals. the authors noted a trend in interest in the topic of information storage and retrieval, with a de-emphasis on classification and indexing and a strengthened emphasis on information systems and retrieval.19 this study deviated from al-sabbagh and related studies of interdisciplinarity—though it employed a similar methodology—in that it examined trends or subtopics within the discipline of lis. though it is not a primary focus of the present study, the use of subtopics to further divide the discipline of library science and examine what aspects (management, technology, cataloging, reference) of the discipline are the focus of cited publications is incorporated in several tables in the results section. methods all references from the 878 articles published in the jla/ital journals (n=7,575) were transcribed to an excel spreadsheet for analysis (this spreadsheet can be found as a supplemental file [https://ejournals.bc.edu/index.php/ital/article/view/10875/9469]). the spreadsheet includes separate columns for primary author, title, publisher, and discipline of each reference. the list of

aspects ranging from the biology and evolutionary history of homo sapiens to the features of society and culture that decisively distinguish humans from other animal species. to determine the discipline in which a cited publication would be classified, the researcher used the cited publication’s title, abstract, and journal to select the most appropriate discipline from the table. in those cases where a source could not be easily identified as falling within one specific discipline, the researcher conferred with additional reviewers (professional librarians) to determine the best fit. information technology and libraries | june 2019 23 several analyses of this data were conducted to explore various aspects of jla/ital’s publication history. for the complete data of the publication’s 51 volumes, the top ten most referenced authors, articles, publishers (journals/publishing houses/organizations/websites), and disciplines were identified with the aid of excel’s functions. the same was done separately for both the jla’s 14 volumes and ital’s 37 volumes. this will allow for the comparison of the journal before and after the 1982 rebranding. the 51 volumes of jla/ital were also divided into the five decades of its history: 1968-77, 1978-87, 1988-97, 1998-2007, 2008-18 (eleven volumes instead of ten). for each of these decades, the top ten authors, publishers, and disciplines were identified. for each of the three categories, a table was created to show the top ten of each decade side-by-side. lastly, the titles of the 7,575 cited publications in jla/ital articles were examined using a content analysis, to identify major concepts and themes that appear to have influenced jla/ital articles. nvivo content analysis software was utilized for this analysis. titles were fed from the excel spreadsheet into the nvivo software, and the word frequency tools were used to identify the most frequently used terms and “generalizations,” or types or themes of statements in the titles.20 results table 2 displays the top ten most-cited authors, articles, publishers/publications, and disciplines throughout ital’s fifty-year history. among the authors, four of the top six are associated with two institutions: library of congress and oclc. there are four corporate or nonprofit organizations, three academics (associated with institutions of higher education), two women and four men. of the top ten articles, eight were published before 1973; three were published in jla/ital and five were published in journals versus five in other (non-journal) publications. of the top ten publishers, seven are journals; five of the publishers are directly associated with library science. within the disciplines, lis represents 60 percent of the total. there are 31 total disciplines represented throughout the 51 volumes, a greater number of disciplines than identified in al-sabbaugh’s study of jasist. table 3 displays the results for jla. jla emerged at the same time as the machine-readable catalog (marc) and oclc, and this is evident in the authors, articles, and publishers cited in the journal. during this phase of the journal’s history, the top three authors—fred kilgour, the library of congress, and henriette avram—dominated the citations. these three authors were cited more than the next seven combined (143 to 101). the cited publications during this period reflected a focus on systems, corporate, and government publications. results for the 37 volumes of ital are displayed in table 4. during this period, marshall breeding emerged as one of the biggest influences on information technology and libraries. all but two of the top articles (larson and bizer) were written before 1985. while six publishers were the same as with jla, three of these six (library of congress, association for computing machinery, and college and research libraries) changed position in the top ten. the disciplines of systems, psychology, educational and instructional design rose, while government, corporate, management, linguistics, and electrical engineering dropped; library science, information science, and computer science remained at the top. 50 years of ital/jla | lund 24 https://doi.org/10.6017/ital.v38i2.10875 table 2. overall most cited. top ten authors (affiliation) top ten articles top ten publishers top ten disciplines

decade are shown in table 5. for the first two decades, fred kilgour was a dominate influence, receiving 15 more citations than the next closest author (the library of congress). in the third decade, kilgour dropped entirely from the top ten and was supplanted at the top spot by karen markey, professor at the university of michigan. during the fourth decade, in the wake of cipa and the u.s. patriot act, the library of congress rose to the top spot and john information technology and libraries | june 2019 27 bertot and paul jaeger, who wrote extensively on these topics and their legal, social, and administrative implications, rose up the list. web resources, such as google, also began to emerge in the fourth decade. in the final decade, breeding, who writes on library systems as

were replaced by instructional design and education in the final two decades. sociology appears in four of five decades, while psychology appears in three of five. in the first two decades, electrical

fifth decade saw greater diversification of subtopics under library science, which led to “information science” supplanting “library science—technology” in the top spot. instructional design and archival science emerged from disciplines not discussed in the first decade to become some of the most important disciplines of the fifth decade. the library science subtopics of accessibility and teaching grew significantly as the roles of the librarian evolved. 50 years of ital/jla | lund 30 https://doi.org/10.6017/ital.v38i2.10875 table 8. first ten years vs. last eleven years disciplines

biggest themes and most frequently used terms throughout jla/ital’s 51 volumes. library is the most common theme and term. the library catalog, and the associated concept of the integrated library system (ils), influence the second and third themes. “online” is an interesting theme/term for the different ways in which it was used throughout the history of the journal. in the early years, “online” was used to refer to the retrieval of computerized bibliographic information; in later years, “online” came to refer almost exclusively to the use of the world wide web. rounding out the top ten terms are several that associated with the study of information science: data, bibliography, and retrieval. finally, table 10 depicts the top ten themes for each of ital’s five decades. libraries remained at the top for all decades; the second spot, however, shifted dramatically. in the first decade, with marc being a major topic of discussion, “system” and “catalog” rose to the top. in decades two and three, with the melding of the disciplines of library science and information science, “information” rose to the top. in the final two decades, the world wide web was influential on the ital discourse. users, usability, and accessibility remain an important theme throughout the history of the journal. 50 years of ital/jla | lund 32 https://doi.org/10.6017/ital.v38i2.10875 table

disciplines, seminal sources, influences, and influencers that may benefit potential authors in determining whether their manuscript is suitable for publication in a specific discipline or journal.21 the results of this study demonstrate that ital is undoubtedly a library science journal, but that it invites a high-level of interdisciplinarity and has experienced a growing impact from the disciplines of information science, computer science, and information systems (which combined presently comprise about 30 percent of total ital references). throughout the journal’s history, there has been an emphasis on library systems, particularly systems for library cataloging. recently, however, there has also been an emphasis on technology, law, and the library as well as instructional technology, teaching, and the library. ital authors take the majority of their citations/ideas from other ital articles, jasist, acm, and other library technology (library hitech, d-lib) and academic librarianship (college and research libraries, journal of academic librarianship) journals. some of the major authors to read to familiarize oneself with the history and themes of the ital publication include fred kilgour, henriette avram, karen markey, and marshall breeding. these are some findings that potential ital authors may find practical use while preparing crafting their research and writing. with ital having a sustained role as a leading publication in library and information science, this study may have some generalizable findings for the discipline. in 2015, richard van noorden produced an interactive chart of the interdisciplinarity of a variety of disciplines, based on data from web of science and the national science foundation.22 if ital is considered representative of a sub-discipline called “library and information science—technology,” it can be compared to the interdisciplinarity of the disciplines listed in van noorden’s study. in the last decade of ital, 45.4 percent of citations came from outside of lis. compared to van noorden’s findings, only 42 of 144 (29 percent) “fields” (or “disciplines,” as they have been referred to as in this study) have a higher proportion of references to outside disciplines. this lis-tech sub-discipline would have a level of interdisciplinarity comparable to the fields of oceanography, botany, philosophy, history, and psychology, and on-par with the average for all social sciences.23 this shows that the discipline certainly has its own proprietary knowledge-base to build upon, but also values the contributions of knowledge from other disciplines. though it is not necessarily the purpose of this study to examine the influence of ital on other journals and within the discipline of lis, some of this information can be gathered rather easily from google scholar (by searching for the journal and comparing the number of citations for each article, as displayed by scholar) and is worth sharing. table 11 shows the top ten most-cited articles published over the history of jla/ital, with mcclure’s 1994 article “network literacy: a role for libraries,” receiving the most references of any article published in the journal. three ital articles have been cited by articles which themselves have over 1,000 citations, including one article (2007’s “checking out facebook.com”) that has been cited by an article which itself has been cited over 10,000 times. fifty-seven ital articles have at least 57 citations, giving the journal an h-index24 of 57. 50 years of ital/jla | lund 34

limitations to this study. this bibliometric analysis was conducted in the “old-fashioned” way, using excel and hand-typing out all 7,575 cited publications. this was deemed the most effective way to collect the data, based on the availability of ital journal, but did take a great deal of time. to save time in recording data, only the first author for each cited publication was listed and no publication dates were collected, nor were abstracts retained and analyzed (which may provide additional compelling details about the content of these cited publications). greater validity for the assignment of disciplines to cited publications may be achieved by having a large team of researchers for analysis, or using multiple researchers for all citations, not just those that the first researcher deems questionable.25 as with a content analysis, independent review of data and comparison and compromising of coding is likely to provide the most consistent and accurate results. information technology and libraries | june 2019 35 conclusion fifty-one volumes of the journal of library automation/information technology and libraries have been published, over which time library technology has evolved from early-marc, a time in which the exceptional library would have perhaps a single computer for “online retrieval,” to the internet age, characterized by personal computing, library management systems, and technology-aided instruction. as time has passed, many of the major influences on the journal have changed, yet the journal has remained one of the most influential for library and information science technology. increased interdisciplinarity in cited publications and new directions in information law and education offer new directions as the journal enters its sixth decade. endnotes 1 imad al-sabbagh, “evolution of the interdisciplinarity of information science: a bibliometric study” (phd diss., florida state university, 1987). 2 ibid. 3 encyclopedia britannica,

(ipl): an exploratory case study on user perceptions environment. digital and physical holdings, academic and public libraries, free and subscription resources, internet encyclopedias, and a multitude of other offerings form a complex (and often overwhelming) informationseeking environment. to move forward effectively and to best serve its existing and potential users, the ipl must pursue a path that is adapted to the present state of the internet and that is user-informed and user-driven. recent large-scale studies, such as the 2005 oclc reports on perceptions of libraries and information resources, have begun to explore user perceptions of libraries in the complex internet environment.3 these studies emphasize the importance of user perceptions of library use, questioning whether libraries still matter in the rapidly growing infosphere and what future use trends might be. in the internet environment, user perceptions play a key role in use (or nonuse) of library resource and services as information-seekers are faced with myriad easily accessible electronic information sources. the ipl’s name, for example, may or may not be perceived as initially helpful to users’ information-seeking needs. repeat use relates to such perceptions as well, in the amount of value users perceive in the library resources over the many other sources available. in beginning to explore such issues, there is a need for current research addressing user perceptions of an internet public library: what the name implies to both existing and potential users as well as the associated functions and resources that should be offered. in this study, we present an exploratory case study on public perceptions of the ipl. using qualitative analysis of interviews with ten college students, some of whom are current users of the ipl and others with no exposure to the ipl, begins to yield an understanding of the public perception of what an internet public library should be. this study seeks to expand our understanding of such issues and explore the present-day requirements for the ipl in addressing the following research questions: ■■ what is the public perception of an internet public library? ■■ what services and materials should an internet public library offer? ■■ background the ipl: origins and research in 1995, joe janes, a professor at the university of michigan’s school of information and library studies, ran a graduate seminar in which a group of students created a web-based library intended to be a hybrid of both physical library services and internet resources and offerings. the resulting ipl would take the best from both the physical and digital the internet public library (ipl), now known as ipl2, was created in 1995 with the mission of serving the public by providing librarian-recommended internet resources and reference help. we present an exploratory case study on public perceptions of an “internet public library,” based on qualitative analysis of interviews with ten college student participants: some current users and others unfamiliar with the ipl. the exploratory interviews revealed some confusion around the ipl’s name and the types of resources and services that would be offered. participants made many positive comments about the ipl’s resource quality, credibility, and personal help. t he internet public library (ipl), now known as ipl2, is an online-based public service organization and a learning and teaching environment originally developed by the university of michigan’s school of information and currently hosted by drexel university’s ischool. the ipl was created in 1995 as a project in a graduate seminar; a diverse group of students worked to create an online space that would be both a library and an internet institution, helping librarians and the public identify useful internet resources and content collections. with a strong mission to serve and educate a varied community of users, the ipl sought to help the public navigate the increasingly complex internet environment as well as advocate for the continuing relevance of librarians in a digital world. the resulting ipl provided online reference, content collections (such as ready reference and a full-text reading room), youth-oriented resources, and services for other librarians, all through its free, web-based presence.1 currently, the ipl consists of a publicly accessible website with several large content collections (such as “potus: presidents of the united states”), sections targeted toward teens and children (“teenspace” and “kidspace”), and a question and answer service where users can e-mail questions to be answered by volunteer librarians.2 there has been an enormous amount of change in the internet and digital libraries since the ipl’s inception in 1995. while web use statistics, user feedback, and incoming patron questions indicate that the ipl remains well-used and valued, there are many questions about its place in an increasingly information-rich online monica maceli (mgm36@drexel.edu) is a doctoral student, susan wiedenbeck (susan.wiedenbeck@drexel.edu) is a professor, and

public library (ipl) | maceli, wiedenbeck, and abels 17 there has also been a continuous evaluation of the role of the library in an increasingly digital world, a question janes sought to address in his first imaginings of the ipl. a study conducted in 2005 claimed that “electronic information-seeking by the public, both adults and children, is now an everyday reality and large numbers of people have the expectation that they should be able to seek information solely in a virtual mode if they so choose.”12 this trend in electronic information-seeking has driven both public and academic libraries to create and support vast networks of licensed and free online information, directories, and guides. these electronic offerings, which (at least in theory) are desired and appreciated by users, are often overshadowed by the wealth of quickly accessible information from tools such as search engines.13 in competition with quickly accessible (though not necessarily credible or accurate) information sources, librarians have struggled to find their place and relevance in an evolving environment. google and other web search engines often shape users’ experiences and expectations with information-seeking, more so than any formal librarian-driven instruction such as in boolean searching. several recent comprehensive studies have explored user perceptions of libraries, both physical and digital, in relationship to the larger internet. abels explored the perspective of libraries and librarians across a broad population consisting of both library users and non-users.14 her findings included the fact that web search engines were the starting point for the majority of information-seeking, and that there is a high preference among users for virtual reference desk services. she proposed an information-seeking model in which the library serves as one of many internet resources, including free websites and interpersonal sources, and is likely not the user’s first stop. in respect to this model of information-seeking, abels suggests that “librarians need to accept the broader framework of the information seeker and develop services that integrate the library and the librarian into this framework.”15 in 2005, oclc released what is possibly the most comprehensive study to date of the public’s perceptions of library and information resources as explored on a number of levels, including both the physical and digital environments.16 findings relevant to libraries on the internet (and this study) included the following: ■■ 84 percent of participants reported beginning an information search from a search engine; only 1 percent started from a library website ■■ there was a preference for self-service and a tendency to not seek assistance from library staff ■■ users were not aware of most libraries’ electronic resources ■■ college students have the highest rate of library use ■■ users typically cross-reference other sites to validate their results worlds while developing its own unique offerings and features.4 janes had conceived the idea in 1994, when the internet’s continued growth began to make it clear that the role of libraries and librarians would be forever changed as a result. janes’ motivating question was “what does librarianship have to say to the network environment and vice versa?”5 the ipl tackled a broad mission of enhancing the value of the internet by providing resources to its varied users, educating and strengthening that community, and (perhaps most unique at the time) communicating “its’ creators vision of the unique roles of library culture and traditions on the internet.”6 initial student brainstorming sessions yielded the priorities that the ipl would address and included such services as reference, community outreach, and youth services. the first version of the ipl contained electronic versions of classic library offerings, such as magazines, texts, serials, newspapers, and an e-mail reference service. the ipl was well received and continued its development, adding and expanding resources to support specific communities such as teens and children. the ipl was awarded several grants over the next few years, allowing for expansion and continuation.7 a wealth of librarian volunteers, composed of students and staff, contributed to the ipl, in particular toward the e-mail reference services. with a stated goal of responding to patrons’ questions within one week, the reference services provide help and direct contact with the ipl’s user base, many of whom are students working on school assignments.8 the ipl’s collections are discoverable through search engines (popular offerings such as the “potus: presidents of the united states” resources rank highly in search results lists) and through its presence on social networking sites such as myspace, facebook, and twitter. additionally, ipl distributes brochures to teachers and librarians at relevant conferences. the ipl has been the focus of many research studies covering a broad range of themes, such as its history and funding, digital reference and the ipl’s question-andanswer service, and its resources and collections.9 also, in line with the original mission of the ipl, janes developed the internet public library handbook to share best practices with other librarians.10 the majority of publications, however, have focused on ipl’s reference service, which is uniquely placed as a librarian-staffed volunteer digital reference service. as the ipl has collected and retained all reference interactions since its inception in 1995, there is a wealth of data readily available to such studies and exploratory work into how best to analyze it.11 user perceptions of digital libraries the internet is a vastly different world than it was in the early days of the ipl’s creation. the expectations of library patrons, both in digital and in physical environments, have changed as well. and as the internet evolves 18 information technology and libraries | march 2011 of the public, which is the intention of this study. ■■ method this exploratory study consisted of a qualitative analysis of data gathered from interviews and observations of ten college student participants who were academic library users and nonusers of the ipl. a pilot study preceded the final research effort and allowed us to iteratively tailor the study design to best pursue our research questions. our initial study design incorporated a usability test portion, in which users were presented with a series of information-seeking needs and instructed to use the ipl’s website to answer the questions. however, we later dropped this portion of the study because pilot results found that it contributed little to answering our research questions about public perceptions; it largely explored implementation details, which was not the focus of this study. following the pilot study, we recruited ten drexel university students from the university’s w. w. hagerty library. this ensured recruiting participants who were at least minimally familiar with physical libraries and who were from a variety of academic focuses. the participant group included eight females and two males—two were graduate students, eight were undergraduates—from a variety of majors, including biology, biomedical engineering, business, library science, accounting, international studies, and information systems. participants took an average of twenty-six minutes to complete the study. the study consisted of a short interview to assess the user’s experience with public libraries (both physical and online) and their expectations of an internet public library. these open-ended questions (included in the appendix) sought to determine what features, services, or content were desired or expected by users, whether the term of “internet public library” was meaningful, if there were similarities to web-based systems that the participants were already familiar with, or if they had previously used a website they would consider an internet public library. all interviews were audio recorded and transcribed. an initial coding scheme was established and iteratively developed (table 1). once we observed significant overlap between participant responses, the study then proceeded to the final analysis and presentation, using inductive qualitative analysis to code text and identify themes from the data.22 ■■ findings all participants were current or former public library patrons; six participants (p1, p4, p5, p6, p8, and p9) were a portion of the study focused on library identity or brand in the mind of the public; participants found the library brand to be “books,” with no other terms or concepts coming close. as a companion report to this study, oclc released a report focused on the library perceptions of college students.17 as our study uses a college student participant base, oclc’s findings are highly relevant. the vast majority of college students reported using search engines as a starting point for informationseeking and expressed a strong desire for self-service library resources. as compared to the general population, however, college students have the highest rate and broadest use of both physical and digital library resources and a corresponding high awareness of these services. the relationship between public libraries and the internet was explored in depth in a 2002 study by d’elia et al.18 the study sought to systematically investigate patrons’ use of the internet and of public libraries. findings included the fact that the internet and public libraries are often complementary; that more than half of internet users were library users and vice versa; and that libraries are valued more than the internet for providing accurate information, privacy, and child-oriented spaces and services. participants made a distinction between the service characteristics of the public library versus those of the internet. many of the most-valued characteristics of the internet (such as information that is always available when needed) were not supported by physical libraries because of limited offerings and hours. in addition to large, comprehensive surveys, there have been several case-study approaches, exploring user perceptions of a particular digital library or library feature. tammaro researched user perceptions of an italian digital library, finding the catalog, online databases, and electronic journals to be most valued; she found speed of access, remote access, a larger number of resources, and personalization to be key digital library services.19 this study also reported a consistent theme in digital library literature: a patron base primarily consisting of novice users who do not know how to use the library and are unaware of the various services offered. crowley et al. evaluated an existing academic library’s webpages for issues and user needs.20 they identified issues with navigational structures and overly technical terminology and a general need for robust help and extensive research portals. in respect to our study, we found no literature that studied perceptions of internet public libraries. as mentioned earlier, research that addressed the ipl from the perspective of its patrons largely focused on ipl’s reference services. in 2008, ipl staff reported 13,857 reference questions received and 9,794,292 website visitors.21 although reference is clearly a vital and well-used service, there is also a great deal of website collection use that must be researched. recent literature does not address the current state of the ipl from the perspective the internet public library (ipl) | maceli, wiedenbeck, and abels 19 of such a library. a few remained confused about how such a concept would relate to physical public libraries and the internet in general. one participant assumed that such a term must mean the web presence of a particular physical public library. another’s immediate reaction was to question the value of such a venture in light of existing internet resources: “i mean, the internet is already useful, so i don’t know [how useful it would be]” (p2). two other participants found meaning in the term by associating it with a known library website, such as that of their academic library or local physical public library. when asked what websites seem similar in function or appearance to what they would consider an internet public library, responses varied. while most participants could not name any similar website or service, one mentioned several academic library websites that he was familiar with, another described several bookseller websites (amazon.com, half.com, and abebooks.com), and a third mentioned wikipedia (but then immediately retracted the statement, after deciding that wikipedia was not a library). theme 2: quick and easy, but still credible participants were highly enthusiastic about the perceived benefits in access to and credibility of information from an internet public library. ease of use and faster information access, often from home, were key motivators for use of internet-based libraries, both public and academic. as described earlier, there is a wealth of competing information options freely available on the internet. given this, participants felt that an internet public library would offer the most value because of its credible information: i like the ready reference [almanacs, encyclopedias]. . . . i’m not used to using any of these, wikipedia is just so ready and user friendly. it’s so easy to go to wikipedia but it’s not necessarily credible. . . . whereas i feel like this is definitely credible. it’s something i could use if i needed to in some sort of academic setting. (p10) theme 3: lack of differentiation between public and academic; physical and digital libraries for many participants, there was confusion about what was or was not a public library, and they initially considered their academic library in that category. overall, participants did not think of public and academic libraries (physical or on the internet) as distinctly different; rather they were more likely to be associated with phase of life. participants that were not current public library users reported using public libraries frequently during their years of elementary education. for participants that were current public library users, physical public libraries (and other local academic libraries) were used to fill in the gaps current public library users, and four (p2, p3, p7, and p10) had used public libraries in the past but were no longer using their services. two participants were graduate students (p3 and p9) with the remainder undergraduates, and two of the ten students had used the ipl website before (p3 and p6). the participants could be characterized as relatively infrequent public library users with a strong interest in the physical book holdings of the public library, primarily for leisure but frequently for research as well. several participants mentioned scholarly databases that were provided by their public library (typically from within the library or online with access using a public library card). there was also interest in leisure audiovisual offerings and in using the library as a destination for leisure. the following themes illustrate our main findings with respect to our research questions. as described above, we conceptualized our raw data into broad themes through an iterative process of inductive coding and analysis. although multiple themes emerged as associated with each of our research questions, we present only the most important and relevant themes (see table 2). all themes were supported by responses from multiple participants. we will further elaborate the themes discovered later in this section; a selected relevant and meaningful participant quote illustrates each theme. theme 1: confusion about name “internet public library” was not an immediately clear term to four of the participants; the six other participants were able to immediately begin describing their concept table 1. inductive coding

technology and libraries | march 2011 would contain both electronic online items and locally available items in physical formats. in particular, connections to local physical libraries to share item holdings and availability status were desired: “general book information and maybe a list of where books can be found. like online, the local place you can find the books.” (p7) given that information-seeking, for this group, was conducted indiscriminately across physical and digital libraries, this integrated view into local physical resources seems to be a natural request. theme 6: personal and personalized help although no participants claimed that reference was a service that they typically use during their physical public library experiences, it was a strong expectation for an internet public library and mentioned by nearly every participant. when questioned as to how this reference interaction should take place, there was a clear preference for communicating via instant message: “reference information. . . . you know, where you have real people. a place where you can ask questions. . . . if you think you can get an answer at a library, then online you would hope to get the same things.” (p1) in addition to being able to interact with a “real” librarian, participants desired other personalized elements, such as resources and services dedicated to information needy populations (like children) as well as resources supporting the community and personal lifestyle issues and topics (like health and money). ■■ discussion in summary, we characterized the participants in this case study as low-frequency physical public library users with a high association between life phase (high school or grade school) and public library use. participants looked to public libraries to provide physical books—primarily for leisure but often for research use as well—leisure dvds and cds, scholarly databases, and a space to “hang for items that could not be located at their school’s academic library, either through physical or digital offerings. consistent with this finding, a few participants reported conducting searches across both local academic and public libraries in pursuit of a particular item. there was a general disregard for where the item came from, as long as it could be acquired with relatively little effort from physically close local or online resources. however, participants reported typically starting with their academic libraries for school resources and the public libraries for leisure materials “i go to the philadelphia public library probably once a month or so usually for dvds but sometimes for books that i can’t find here [academic library]. . . . i usually check here first because it’s closer.” (p5) theme 4: electronic resources, catalog, and searching tools are key there were many participant comments, and some confusion, around what type of resources an internet public library would provide, as well as whether they would be free or not (one participant assumed there would be a fee to read online). the desired resources (in order of importance) included leisure and research e-books, scholarly databases, online magazines and newspapers, and dvds and cds (pointers to where those physical items could be found in local libraries). a few comments were negative, assuming the resources provided would only be electronic, but participants were mostly enthusiastic about the types and breadth of resources that such a website would offer. for example, one participant commented, “i think you could get more resources. . . . the library i usually visit is kind of small so it’s very limited in the range of information you can find.” (p4) many participants emphasized the importance of providing robust, yet easy-to-use, search tools in managing complex information spaces and conveying item availability. theme 5: connections to physical libraries several participants assumed that the resource collection

connections to physical libraries personal and personalized help the internet public library (ipl) | maceli, wiedenbeck, and abels 21 infosphere—their services and collections both physical and virtual.25 this is, like many issues in library systems design, a complex challenge. as previous research has shown, extending the metaphor of the physical library into the digital environment does not always assist users, especially when they may be more likely to draw on previous experiences with other internet resources.26 the original prospectus for the internet public library, as developed by joe janes, acknowledges the different capabilities of physical libraries and libraries on the internet, claiming that the ipl would “be a true hybrid, taking the best from both worlds but also evolving its own features.”27 if users anticipate an experience similar to the internet resources they typically use (such as search engines), then the ipl may best serve its users by moving closer to “internet” than “library.” however, such a choice may entail unforeseen tradeoffs. several participants in this study mused over what physical public library characteristics would carry over to a digital public library and the potential tradeoffs: “you wouldn’t have to leave your home but at the same time i think it’s easier to wander the library and just see things that catch your eye. and i like the quiet setting of the library too.” (p8) another participant mentioned the distinctly positive public library experience, and how such an experience should be reflected in an internet-based public library: “i think that public libraries have a very positive reputation within communities. and i don’t think it would be bad for an internet public library to move toward that expectation that people have.” (p3) the question remains, then, whether the ipl can compete with a multitude of other internet resources without losing the familiar and positive essence of a traditional physical public library. or rather, how can the ipl find a way to translate that essence to a digital environment without sacrificing performance and user expectations of internet services? ■■ conclusion during this study, participants described an internet public library that, in many ways, takes the best features of several currently existing and popular websites. an internet public library should contain all the information of wikipedia, yet be as credible as information received directly from your local librarian. it should search across both websites and physical holdings, like abebooks.com or a search aggregator. it should search as powerfully and as easily as google, yet return fewer, more targeted results. and it should provide real-time help immediately and conveniently, all from the comfort of your home. out” or occupy leisure time. for the participants, an internet public library (an occasionally confusing term) described a service you could access from home, which included electronic books, information about locally available physical books, scholarly databases, reference or help services, and robust search tools. it must be easy to use and tailored to needy community populations such as children and teens. for several participants it would be similar to existing bookseller websites (such as amazon. com or abebooks.com) or academic library websites. in exploring how these findings can inform the future design and direction of the ipl, it is again necessary to reflect on the values and concepts that inspired the original creation of the ipl. the initial choice of the ipl’s name was intended to reflect a novel system at the time, as joe janes detailed in the ipl prospectus: “i would view each of those three words as equally important in conveying the intent of this project: internet, public, and library. i think the combination of the three of them produces something quite different than any pair or individual might suggest.”23 all three of these concepts—internet, public, and library—have evolved with the changing nature of the internet. and, as the research explored would indicate, there may not be a distinct boundary between these concepts from the perspective of users. our finding that participants seek information by indiscriminately crossing public and academic libraries, as well as digital and physical resource formats verifies earlier research efforts.24 as the amount of information accessible on the internet has expanded, the boundary of the library can be seen as either expanding (providing credible indexing, pointers, and information about useful resources from all over the internet), contracting (primarily providing access to select resources that must be accessed through subscription), or existing somewhere in between, depending on the perspective. in any of these cases, it is vital that the ipl present its resources, services, and offerings such that its value and contribution to information-seeking is highlighted and clear to users. amorphously placed in a complex world of digital and physical information, the ipl must work toward creating a strong image of its offering and mission; an image that is transparent to its users, starting with its name. this challenge is not the ipl’s alone, but rather that of all internet library portals, resources, and services. the 2005 oclc report on perceptions of libraries expressed the importance of a strengthened image for internet libraries: libraries will continue to share an expanding infosphere with an increasing number of content producers, providers and consumers. information consumers will continue to self-serve from a growing information smorgasbord. the challenge for libraries is to clearly define and market their relevant

complex, far-reaching, and labor-intensive requirements. and many of these requirements are currently difficult and unresolved challenges to digital libraries in general, not simply the ipl. this preliminary study is limited in its college student participant base and small sample size, which may not reflect perspectives of the greater community of ipl users. these results therefore may not be generalizable to other populations who are current or potential users of the ipl, including other targeted groups such as children and teens. additionally, our chosen participant group, college students who are physical library users, had relatively high levels of library and technology experience, as well as complex expectations. our results would likely differ with a participant group of novice internet users. as detailed above, this study explores public perceptions of an internet public library—an important aspect of the ipl that is not well studied and that has implications on ipl use and repeat use. while the ipl was carefully and thoughtfully constructed by a dedicated group of librarians, students, and educators, there has not been a recent study devoted to understanding what an internet public library should be today. more recently, in january 2010, the ipl merged with the librarians’ internet index to form ipl2. the two collections were merged and the website was redesigned. although this merger was because of circumstances unrelated to our research, our findings were leveraged during the redesign (for example, in naming the collections). in the future, our findings can be used in further ipl2 design iterations or explored in subsequent research studies in the specific context of ipl2 or of digital libraries in general. as discussed above, this study may be extended to different participant populations and to existing but remote ipl2 users. this study may also be continued in a more design-oriented direction to explore the usability and user acceptance of ipl2’s website. references 1. joseph janes, “the internet public library: an intellectual history,” library hi tech 16, no. 2 (1998): 55–68. 2. “about the internet public library,”

two records describing the same intellectual creation or work (e.g., shakespeare’s othello) can vary by physical form and other attributes. two records describing both the same work and exactly the same form can differ from each other if the records were created under different rules of record description (catalog­ ing). two records intended to describe the same object can vary unintentionally if typographical or other entry errors are present in one or both. thus sorting out significant from insignificant differences is critical. an example of the challenges of developing matching software in the metadata capture project is described elsewhere.3 the scope of misinformation is limited to information storage and retrieval, and specifically to comparison of incoming records to candidate matches in the database. the authors define misinformation as follows: 1. anything that can cause two database records, i.e., representations of different items to be mistaken as representations of the same item. these can lead to inappropriate merging or updates. 2. the effect of techniques or processes of search that can obscure distinctions in differing items. 3. any case where matching misses an appropriate match due to nonsignificant differences in two records that really represent the same item. note that disinformation (the intentional effort to mis­ represent) is not considered in scope for this discussion. the assumption is that cooperation is in the interests of all parties contributing to a shared database. we do not assume that all institutions sharing the database have the same goals. misinformation and bias in metadata processing | thornburg and oskins 15 misinformation and bias in metadata processing: matching in large databases gail thornburg and w. michael oskins gail thornburg (thornbug@oclc.org) has taught at the university of maryland and the university of illinois, and served as an adjunct professor at kent state university, and as a senior-level software engineer at oclc. w. michael oskins (oskins@oclc.org) has worked as a developer and researcher at oclc for twenty years. 16 information technology and libraries | june 200716 information technology and libraries | june 2007 what is bias? bias can be defined as factors in the creation or processing of database records that feed on misinformation or missing information, and skew charac­ terizations of the database records in question. context—matching and bias how are matching and bias related to each other? the growth of a database is in part a function of the matching process. if matching is not tuned correctly, the database can grow or change in nonoptimal ways. another way to look at the problem is to consider the goal of success in searching, and the need to know when to stop. human beings recognize that failure to find the best information for a given problem may be costly. finding the best information when less would suffice may also be costly. systems need to know this. for a large shared data­ base, hundreds of thousands of records may be processed in a day; the system must be as efficient as possible. what are some costs? fail to match when one should, and duplicates may proliferate in the database. match badly, and there is risk of merging multiple records that do not represent the same item. a system of matching can fail in more than one way. balance is needed. 1. searches, which are based on data in the incom­ ing record, may be too precise to find legitimate matches. loosen the criteria too much, and the search may return too many records to compare. 2. once retrieved, candidate matches are evaluated. compare candidates too narrowly, and records with insignificant differences will be rejected. fail to take note of salient differences between incom­ ing record and database record, and the match will be wrong, undetected, and potentially hard to detect in the future. the goals vary in different matching projects. for some projects, setting “holdings,” the indication that a member library owns a copy of something, is the main goal of the processing. this does not involve adding, replacing, or merging database records. for other projects, the goal is to update the database, either by replacing matched records, merging multiple duplicate records into one, or by adding new records if no match is found in the database. for the latter, bad matching could compromise database contents. n background hickey and rypka provide a good review of the problems of identifying duplicates and the implications for match­ ing software.4 their study notes concerns from a variety of library networks including that of the university of toronto (utlas), washington library network (wln), and research libraries group (rlin). they also refer­ ence studies on duplicate detection in the illinois state­ wide bibliographic database and at oak ridge national laboratories. background discussion of broader misinfor­ mation issues in shared library catalogs can be found in bade’s paper.5 a good, though dated, review of duplicate record problems can be found in the o’neill, rogers, and oskins article.6 the authors discuss their analysis of differences in records that are similar but not identical, and which elements caused failure to match two records for the same item. for example, when there was only one differing element in a pair, they found that element was most often publication date. their study shows the difficulties for experts to determine with certainty that a bibliographic record is for the same item. problems of typographical errors in shared biblio­ graphic records come under discussion by beall and kafadar.7 their study of copy cataloging errors found only 35.8 percent were corrected later by libraries, though the ordinary assumption is that copy cataloging will be updated when more information is available for an item. pollock and zamora report on a spelling error detection project at chemical abstracts service (cas) and charac­ terize the types of errors they found.8 chemical abstracts databases are among the most searched databases in the world. cas is usually characterized as a set of sources with considerable depth and breadth. of the four most common typographical errors they describe, errors of omission are most common, with insertion second, substitution third, and transposition fourth. over 90 percent of the errors they found were single letter errors. this is in agreement with the findings of o’neill and aluri, though the databases were substantially different.9 another study on moving­ image materials focuses on problems of near­equivalents in cataloging.10 yee suggests that cataloging practice tends to lead to making too many separate records for near equivalents. owen gingerich provides insight in the use of holdings information in oclc and other bibliographic utilities such as rlin for scholarly research in locating early editions of copernicus’ de revolutionibus.11 among other sources, he used holdings information in multiple bibliographic utilities to help in collecting a census of copies of de revolutionibus, and plotting its movements through europe in the sixteenth century. his article high­ lights the importance of distinguishing very similar items for scholarly research. shedenhelm and burk discuss the introduction of vendor records into oclc’s worldcat database.12 their results indicate that these minimal­level records increase the duplication rate within the database and can be costly to upgrade. (see further discussion in the section change in contributor characteristics below.) one problem in analysis of sources of mismatch in previous studies is that there is no good way to detect and

jasco reviews studies characterizing types and sources of errors.13 sheila intner compares the quality issues in the databases of oclc and the research libraries group (rlg) and finds the issues similar.14 intner used matched samples of records from both worldcat and rlin to list and compare types of errors in the records. she noted that while the perception at that time was that rlin had higher­quality cataloging, the differences found were not statistically significant. jeffrey beall, while focusing in his study on the full­ text online database jstor, notes the commonality of problems in metadata quality.15 in addition, he discusses the special quality problems in a database of scanned images. the scanning software itself may introduce typo­ graphical errors. like xwc, the database changes rapidly. o’neill and visine­goetz present a survey of quality con­ trol issues in online databases.16 their sections on dupli­ cate detection and on matching algorithms illustrate the commonalities of these problems in a variety of shared cataloging databases. they cite variation in title as the most common reason for failure to identify a duplicate record that should match. variations in publisher, names, and pagination were noted as common. lei zeng pres­ ents a study of chinese language records in the oclc and rlin databases.17 zeng discusses quality problems including (1) format errors such as field and subfield tagging and incorrect punctuation; (2) content errors such as missing fields and internal record inconsisten­ cies; and (3) editing and inputting errors such as spacing and misspelling. part 2 of her study presents the results of the prototype rule­based system developed to catch such errors.18 while the author refrains from comparing the quality of oclc and rlin chinese language catalog records, the discussion makes clear that the quality issues are common to a number of online databases. more work is needed on quality and accuracy of shared records in non­roman scripts, or in other lan­ guages transliterated to roman script. n types of bias to be considered specific factors that may tend to bias an attempt to match one record to another include: 1. violated expectations—system software expects data it does not receive, or data received is not well formed. 2. temporal bias—changes in rules and philosophies of record creation over time. 3. design bias—choices in layout of the records, which favor one type of record representation at the expense of another. 4. judgment calls—distinctions introduced in record representations due to differing but legitimate variation in expert judgment. oclc is a multina­ tional cooperative and there is no universal set of standards and rules for creating database records. rules of cataloging most widely used are not abso­ lutely prescriptive and are designed to allow local deviation to meet local needs.19 5. structural bias—process and systems bias. this category reflects internal influences, inherent in the automatic processing, storage, and retrieval of large numbers of records. 6. growth of the database environment—whether in raw numbers of records, numbers of specific formats, numbers of foreign languages, or other characteristics that may affect efficient location and comparison of records. 7. changes in contributor characteristics––in the goals or focus of institutions that contribute to the database. violated expectations data may not conform to expectations. expectations about the nature of records in the data­ bases are frequently violated. what seem to be good rules for matching may not work well if the incoming data is not well formed, or simply not constructed as expected. biasing sources in the incoming data include the fol­ lowing: 1. typographical errors occur in titles and other parts of the record. anywhere the software has to parse text, an entry error—or even correction of an entry error by a later update—could con­ found matching. this could confound both (a) query execution and (b) candidate comparisons. basically the system expects textual data such as the name of a title or publisher to be correct, and machine­based efforts to detect errors in data are expensive to run. spelling detection techniques can compensate in some ways for data problems, but will not identify cases of real­word errors. see kukich for a survey of spelling error, real­word, and context­dependent techniques.20 2. there is also the issue of real word differences in similar text strings. an automated system with programmed fault tolerance may wrongly equate the publisher name “mila” with “mela” when they are distinct publishers. equivalence tables can cross­reference known variations on well­known publisher names, but cannot predict merges and other organizational changes. or consider author names: are “john smith” and “jon smith” the 1� information technology and libraries | june 20071� information technology and libraries | june 2007 same? this is a major problem with automated authority control where context clues may not be trustworthy. 3. errors of formatting of variable fields in the meta­ data contribute to false mismatch. the rules for data entry in the marc record are complex and have changed over time. erroneous placement or coding of subfields poses challenges for iden­ tification of relevant data. the software must be fault tolerant wherever possible. changes in the format of the data itself in these fields/sub­ fields may further complicate record comparisons. isbns (international standard book numbers) and lccns (library of congress control numbers) have both changed format in the recent past. 4. errors occur in the fields that indicate format of the information. in bibliographic records, format information is used to derive the overall type of material being described: book, url, dvd, and so on. errors in the data in combination can generate an incorrect material type for the record. 5. language of cataloging: this comparison has in the past caused inappropriate mismatches. the require­ ments in the new matching aimed to address this. 6. language in formation of queries: marc records frequently are a mixture of languages. as has been seen in other projects with intensive comparison of text, overlap in languages has the potential to confuse comparisons of short strings of text.21 the assumption made here is that the use of all pos­ sible syllables contained in the title should tend to mitigate language problems. nothing short of semantic analysis by the software is likely to solve such a problem, and contextual approaches to detection have had most success (in the produc­ tion environment) in carefully controlled cases. matching overall must be generic in its problem solving techniques. temporal bias large databases developed over time have their contents influenced by changes in standards for record creation, changes in contributor perception of the role of the data­ base, and changes in technology to be described. changes may include the following: 1. description level: e.g. changes such as book or elec­ tronic book. these have evolved from format­ to content­based descriptions that transcend format. over time, the cataloging rules for describing formats have changed. thus a format description created earlier might inadvertently “mismatch” the newer description of exactly the same item. for example, the rules for describing a book on a cd originally emphasized the cd format, whereas now, the emphasis might be shifted to focus on the intellectual content, the fact that it is a book. 2. the role of the database once perceived as chiefly repository or even backup source for a given library has become a shared resource with responsibilities to a community larger than any one library. 3. over time, the use of the database may change. (this is further discussed in the section on growth of the environment later.) searching has to satisfy the reference function of the database, but match­ ing as a process also relies on searching, and its goals are different. 4. varied standards worldwide challenge coopera­ tion. while u.s. libraries usually follow aacr2 and use the marc21 communications format, other parts of the world may use unimarc and country­specific cataloging rules. for instance, the pica bibliotekssystem, which hosts the dutch union catalog, used the prussian cataloging rules, which tended to focus on title entries.22 the switch to the rak was made by the early nineties.23 5. some libraries may not use any form of marc but submit a spreadsheet that is then converted to marc. there is some potential for ambiguities in those conversions due to lack of 1:1 correspon­ dence of parts. 6. even within a country, standards change over time, so that “correct” cataloging in one decade may not match that in a later period. neither is wrong, in its own temporal context, but each results in different metadata being created to describe the same item. intner points out that oclc’s database was initi­ ated a full decade before rlg implemented rlin, and rlin started almost the same time as the aacr2 publication.24 thus rlin had many fewer pre­aacr2 records in its database, while worldcat had many more preexisting records to try to match with the newer aacr2 forms. 7. objects referenced in the database may change over time. for instance, a record describing an elec­ tronic resource may point to a location no longer valid for that resource. 8. vendor records are created as advance advertis­ ing, but there is no guarantee the records will be updated later. estimating the time before updates occur is impossible. 9. records themselves change over time as they are copied, derived, and migrated into other systems. they may be enhanced or corrected in any system where they reside. so when they return to the origi­ nating database, they may have been transformed so far as to be unrecognizable as representations of the same item. this problem is not unique to xwc; public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 1�misinformation and bias in metadata processing | thornburg and oskins 1� it is a challenge for any shared database where export of records and reentry is likely. design bias the title, author, publisher, place of publication, and other elements of a record, designed in a time when most of the contents of a library were books, may not appear as clear or usable for other forms of informa­ tion, such as web sites or software. there is a risk to any design of a representation for an object, that it may favor distinctions in one format over another. or representations imported from other schemes may lose distinctions in the crosswalk from one scheme to another. a crosswalk is a mechanism for the mapping of data elements/content from one metadata scheme to another. dublin core and marc are just two examples of schemes used by library professionals. software exists to convert dublin core metadata to marc for­ mat, but the process of converting less complex data to a scheme of more structured data has inevitable limita­ tions. for instance, dublin core has “subject” while marc has dozens of ways to indicate subject, each with a different kind of designation for subject aspects of an item.25 see discussion in beall.26 libraries commonly exchange or purchase records from external sources to reduce the volume or costs of in­house cataloging. if an institution harvests metadata from multiple sources, there can be varying structures, content standards, and overall quality, all of which can make record compari­ sons error prone. while library and information science professionals have been creating metadata in the form of catalog records for a long time, the wider community of digital repositories may be outside the lis commu­ nity, and have varied understanding of the need for consistent representations of data. robertson discusses the challenges of metadata creation outside the library community.27 museums and archives may take a dif­ ferent view of what quality standards in metadata are. for example, for a museum, extensive detail about the provenance of an object is necessary. archives often record information at the collection level rather than the object level; for example, a box of miscellaneous papers, as opposed to a record for each of the papers within the box. educators need to describe resources such as learning objects. a learning object is any entity, digital or nondigital, which can be used, reused, or referenced during technology­supported learning 28 for these objects a metadata record using the ieee lom standard may be used.29 while this is as complex as a marc record, it has less bibliographic description and more focus on description of the nature and use of the learning object. in short, for one type of institution the notion of appropriate granularity of description may be too detailed or too vague for the needs of another type of institution. judgment calls two persons creating independent records for the same item exercise judgment in describing what is most impor­ tant about the object. one may say it is a book with an accompanying cd, another may say it is software on a cd, accompanied by a book of documentation. another example of legitimate variation is the choice of use of ellipses […] to leave out parts of long titles in a metadata description. one record creator may list the whole title, another may list only the first part followed by the mark of ellipsis to indicate abbreviation of the lengthy title. either is correct, but may not match each other without special techniques. see appendix b for the perils of ellipsis handling. the form of name of a publisher, given other occur­ rences of a publisher name in a record, may be abbrevi­ ated. for instance, in one place the corporate author who is also the publisher might be listed in the author field as “department of health and human services” and then abbreviated—or not—in the publisher area as “the department.” note that there are limitations inherent to the valida­ tion of any system of matching, in that human reviewers may not be able to determine whether two representa­ tions in fact describe the same item. structural bias 1. process bias refers to any features of the software which at run­time may change the way matching is carried out, whether by shortening or lengthen­ ing the analysis, or otherwise branching the logical flow. this can arise from many sources, including but not limited to the following factors. a. there is need for efficient processing of large num­ bers of incoming records. this can force an empha­ sis on speedy matching. that is, matching not required to replace records tends to be optimized to stop searching/matching as early as is reason­ able. in the case where unique key searching finds a single match to an incoming record, it is fairly easy for the software to “justify” stopping. if there are multiple matches found, more analysis may be needed before the decision to stop matching can be made. over time the numbers of records processed has increased enormously. b. matching needs to exploit “unique” keys to speed searching, yet these may not prove to be unique. though agreements are in place for use of numeric keys such as isbns, creation of these keys is not under the control of any one organization. 20 information technology and libraries | june 200720 information technology and libraries | june 2007 c. problems arise when brief records are com­ pared with fuller records. comparisons may be biased inadvertently towards false matches. such sparseness of data has been identified as a problem in rlin matching as well as in xwc. d. at the same time there is bias toward less generic titles in matching. requirements of sys­ tem throughput mandate an upper limit on the size of result set that the matching software will even attempt to analyze. this upper limit could tend to discriminate against effective retrieval of generic titles. matching will reject very large results sets of searches. so the query that has fewer title terms may tend to retrieve too much. titles such as “proceedings” or “bulletin” may be difficult to match if insufficient other informa­ tion is present in the record for the query to use. ironically this can mean addition of more generic titles to the database, since what is there is in effect less findable. e. transparency can contribute to bias in that, for each layer of transparency a layer of opacity may be added, when information is filtered out from a user’s view. that user may be a human or an application. openurl access to “appropriate copy” is an example from the standards world. the complexity of choosing among multiple online copies has become known as the “appro­ priate copy” problem. there are a number of instances where more than one legitimate copy of an electronic article may exist, such as mir­ roring or aggregator databases. it is essentially a problem of where and how to introduce localiza­ tion into the linking process.30 appropriateness reflects the user’s context, e.g., location, license agreements in place, cost, and other factors. 2. systems bias. what is this, really? the database can be seen as “agent.” the weight of its own mass may affect efforts to use its contents. a. for maintainers of large database systems, the goals of database repository and search engine may be somewhat at odds. yet librarians do make use of the database as reference source. b. search strategies for the software that acts as a user of the database is necessarily developed and optimized at a certain point in time. yet a river of new information flows into this data­ base. 1. if the numbers of types of entries in various database indexes grows nonproportion­ ally, search strategies that worked well in the past could potentially fall “out of tune” with the database contents. see growth of the environment section below. 2. change in proportions of languages in the database may render an application’s use of stopword lists less effective. 3. if changes in technology or practice result in new forms of material being described in the database, the software searches using material type as a limiter may not work properly. the software is using abstractions provided by the database, and they need to be kept synchronized. c. automated query construction presents its own problems. the use of boolean searching [term a and term b and term c] is quite restrictive in the sense that there is no “halfway” or flex for a record being included in a set of candidates. matching starts with the most specific search to avoid too­high numbers of records retrieved, and all it can do is drop or rearrange terms from a query in the effort to broaden the results. d. disconnects in metadata object creation/revision are another problem. links can point to broken uris (uniform resource identifiers). controlled vocabularies can drift or expand. even more confusing, a uri that is not broken may point to content which has changed to the point where the metadata no longer describes the item it once did. at one extreme, bruce and hillmann describe the curious case of citation of judicial opinions, for which a record of the opinion may be created as much as eighteen months before the volume with the official citation is printed, and thus the official citation cannot be created.31 e. expectations for creation of metadata play a role as well. traditional cataloging has generally had an expectation that most metadata is being cre­ ated once and reused. yet current practice may be more iterative, and must be, if such problems as records with broken internet uris are to be avoided. f. loss of synchronization can subvert process­ ing. note that other elements of metadata may become divorced or out of synch with the origi­ nal target /purpose. the prefix to an isbn was originally intended to describe the publisher, but is now an unreliable discriminator. numeric keys intended to identify items uniquely can retrieve multiple items, if the scheme for assign­ ing them is not applied consistently. in the worst case, meaningful data elements may become so corrupted as to be useless for record retrieval or even comparison of two records. g. ownership issues can detract from optimal data­ base management. member institutions’ percep­ tions of ownership of individual records can conflict with the goals of efficient search and retrieval. members may resist the idea of a “bet­ public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 21misinformation and bias in metadata processing | thornburg and oskins 21 ter” record being merged with a “lesser” one. so systems have ways of ranking records by source or contents with the general goal of trying to avoid losing information, but with the specific effect of refraining from actions that might be enriching in a given case. growth of the database environment a shared database can grow in unpredictable ways. a change in the relative proportions of different types of materials or topical coverage can render once­effective searches ineffective due to large result sets. an example of this is the number of internet­related entries in xwc. a search such as “dog” restricted to “internet­related” entries in 1995 retrieved thirty­four hits. this might be a manageable number. but in 2005, 225 entries were in the result set. similarly with subject headings, one search on “computer animation” retrieved fourteen hits in 1980, and 342 in 2005. in both cases the result sets grew from manageable to “too large” over time. the increase in the number of foreign language entries in a database can cause problems. just determining what language an entry is in can be difficult, and records may contain multiple languages. also, such languages as chinese, japanese, and korean can overlap. chinese syllables such as: “a, an, to, no, jan, ka, jun, lung, sung, i, lo, la, le, so, sun, juan,” seen out of context might be chinese or any one of several other languages. determining appropriate handling of stopwords and other rules for effective title matching becomes more complex as more languages populate the database. changes in contributor characteristics copy cataloging practices in an institution can affect xwc indirectly. an institution previously oriented to fixing downloaded records may adopt a policy of refrain­ ing from changing downloaded records. historical inde­ pendence of libraries is one illustration. prior to the 1970s, most libraries did not share their cataloging with other libraries. many institutions, especially smaller ones, were outside the loop and did things their own way. they used what rules they felt were useful, if they used any rules at all. later they converted sparse and poorly formed data into marc records and sent them to oclc for matching, perhaps in an effort to get back a more complete and useful record. yet the matching process is not always able to distinguish or interpret these local dialects. changes in specialization of cata­ loging staff at an institution, or cutbacks in staff can lead to reduced facility in providing original cataloging. outsourcing of cataloging work can affect handling of specialized materials as well. the introduction of vendor records and their characteristics has been noted by shedenhelm and burk.32 as they note, these records are very brief bibliographic records originally designed to advertise an item for sale by the vendor. these mini­ mal level records have a relatively high degree of dupli­ cation with existing records (37.5 percent in their study) and because of their sparseness can increase the cost of cataloging. changes in the proportion of contribu­ tors who create records in non­marc formats such as dublin core can affect the completeness of bibliographic entries. the use of such formats, meant to facilitate the entry of bibliographic materials, does come with a cost. group cataloging is a process whereby smaller libraries can join a larger set of institutions in order to reduce costs and facilitate cataloging. this larger group then contributes to oclc’s database as an entity. the growth of group cataloging has resulted in the addition of more records from smaller libraries, which may in the future have an effect on searching/matching in xwc worldcat overall. internationalization may be a factor as well. the marc format is an anglo­based format with english­language­based documentation. rapid inter­ national growth thrusts a broader range of traditions into a marc/oclc world. the role of character sets is heightened as the database grows. a cyrillic record may not be confidently matched to a transliterated record for the same item. although worldcat has a long his­ tory with cjk records, marc and worldcat are not yet accustomed to a wide repertoire of character sets. now, however, xwc is an environment in which expanding character coverage is possible, and likely. future research n we need more systematic study of the types of errors/omissions encountered in marc record cre­ ation. n how can the process of matching accomodate objects that change over time? n how does the conversion from new metadata schemes affect matching to marc records? does it help to know in what format a record arrived, or under what rules it was created? n how can we address sparseness in vendor records or legal citations? how can we deal with other advance publication issues? n how do changes in philosophy of the database affect the integrity of the matching process? n conclusions in this review we have seen that characterizing metadata at a high level is difficult. challenges for adding to a large, complex database include some of the following: 22 information technology and libraries | june 200722 information technology and libraries | june 2007 n rules for expert creation of metadata inevitably change over time. n the object of the metadata itself may change, more often than may be convenient. n comparisons of briefer records to records that are more elaborate descriptions can have pitfalls. search and comparison strategies for such record pairs are challenged by the need to have matching algorithms that work for every scenario. n changes within the database may themselves con­ tribute to exacerbation of matching problems if duplicates are added too often, or records are merged that actually represent different contents. because of the risk, policies for merging and replacing records tend to be conservative, but this does not always favor the greatest efficiency in database processing. n changes in the membership sharing a database are likely to affect its shape and searchability. n newer schemes of metadata representation are likely to challenge existing algorithms for determining matches.

21 abstract like many libraries, the university of minnesota libraries-twin cities now offers a next-generation catalog alongside a traditional online public access catalog (opac). one year after the launch of its new platform as the default catalog, usage data for the opac remained relatively high, and anecdotal comments raised questions. in response, the libraries conducted surveys that covered topics such as perceptions of success, known-item searching, preferred search environments, and desirable resource types. results show distinct differences in the behavior of faculty, graduate student, and undergraduate survey respondents, and between library staff and non-library staff respondents. both quantitative and qualitative data inform the analysis and conclusions. introduction the growing level of searching expertise at large research institutions and the increasingly complex array of available discovery tools present unique challenges to librarians as they try to provide authoritative and clear searching options to their communities. many libraries have introduced next-generation catalogs to satisfy the needs and expectations of a new generation of library searchers. these catalogs incorporate some of the features that make the current web environment appealing: relevancy ranking, recommendations, tagging, and intuitive user interfaces. traditional opacs are generally viewed as more complex systems, catering to advanced users and requiring explicit training in order to extract useful data. some librarians and users also see them as more effective tools for conducting research than next-generation catalogs. academic libraries are frequently caught in the middle of conflicting requirements and expectations for discovery from diverse sets of searchers. in 2002, the university of minnesota-twin cities libraries migrated from the notis library system to the aleph500™ system and launched a new web interface based on the aleph online catalog, originally branded as mncat. in 2006, the libraries contracted with the ex libris group as one of three development partners in the creation of a new next-generation search environment called primo. during the development process, the libraries conducted multiple usability studies that provided data to inform the direction of the product. participants in the usability studies generally characterized the primo interface as “clear” and “efficient.”1 a year later the university heather hessel (heatherhessel@yahoo.com) was interim director of enterprise technology and systems, janet fransen (fransen@umn.edu) is the librarian for aerospace engineering, electrical engineering, computer science, and history of science & technology, university of minnesota, minneapolis, mn. mailto:heatherhessel@yahoo.com mailto:fransen@umn.edu information technology and libraries | june 2012 22 libraries branded primo as mncat plus, rebranded the aleph opac as mncat classic, and introduced mncat plus to the twin cities user community as a beta service. in august 2008, mncat plus was configured as the default search for the twin cities catalog on the libraries’ main website, with the libraries continuing to keep a separate link active to the aleph opac. a new organizational body called the primo management group was created in december 2008 to coordinate support, feedback, and enhancements of the local primo installation. this committee’s charge includes evaluating user input and satisfaction, coordinating communication to users and staff, and prioritizing enhancements to the software and the normalization process. when the primo management group began planning its first user satisfaction survey, the group noted that a significant number of library users seemed to prefer mncat classic. therefore, two surveys were developed in response to the group’s charge. these two surveys were identical in scope and questions, except that one survey referenced mncat classic and was targeted to mncat classic searchers (appendix a), while the other survey referenced mncat plus and was targeted to mncat plus searchers (appendix b). these surveys were designed to produce statistics that could be used as internal benchmarks to gauge library progress in areas of user experience, as well as to assist with ongoing and future planning with regard to discovery tools and features. research questions in addition to evaluating user satisfaction and requesting user input, the primo management group also chose to question users about searching behaviors in order to set the direction of future interface work. questions directed toward searching behaviors were informed by the findings from a 2009 university of minnesota libraries report on making resources discoverable.2 the group surveyed respondents about types of items they expect to find in their searches, their interest in online resources, and the entry point for their discovery experience. the primo management group crafted the surveys to get answers to the following research questions:  how often do users view their searching activity as successful?  how often do users know the title of the item that they are looking for, as opposed to finding any resource relevant to their topic?  what search environments do users choose when looking for a book? a journal? anything relevant to a topic?  how interested are users in finding items that are not physically located at the university of minnesota?  are there other types of resources that users would find helpful to discover in a catalog search? resource discovery: comparative survey results | hessel and fransen 23 although it can be tempting to think of the people using the catalog interfaces as a homogeneous group of “users,” large academic libraries serve many types of users. as wakimoto states in “scope of the library catalog in times of transition,” on the one hand, we have ‘net-generation users who are accustomed to the simplicity of the google interface, are content to enter a string of keywords, and want only the results that are available online. on the other hand, we have sophisticated, experienced catalog users who understand the purpose of uniform titles and library of congress classifications and take full advantage of advanced search functions. we need to accommodate both of these user groups effectively.3 the primo management group planned to use the demographic information to look for differences among user communities; therefore the surveys requested demographic information such as role (e.g., student) and college of affiliation (e.g., school of dentistry). in designing the surveys, the group took into account the limitations of this type of survey as well as the availability of other sources of information. for example, the primo management group chose not to include questions about specific interface features because such questions could be answered by analyzing data from system logs. the group was also interested in finding out about users’ strategies for discovering information, but members felt that this information was better obtained through focus groups or usability studies rather than through a survey instrument. research method the primo management group positioned links to the user surveys in several online locations, with the libraries’ home page providing one primary entry point. clicking on the link from the home page presented users with an intermediate page, where they were given a choice of which survey to complete: one based on mncat plus, and the other on mncat classic. if desired, users could choose to complete a separate survey for each of the two systems. links were also provided from within the mncat plus and mncat classic environments, and these links directed users to the relevant version of the survey without the intermediary page. in addition to the survey links in the online environment, announcements were made to staff about the surveys, and librarians were encouraged to publicize the surveys to their constituents around campus. the survey period lasted from october 1 through november 25, 2009. at the time of the surveys, the university of minnesota libraries was running primo version 2 and aleph version 19. because participants were self-selected, the survey results represent a biased sample, are more extreme than the norm, and are not generalizable to the whole university population. participants were not likely to click the survey link or respond to e-mailed requests unless they had sufficient incentive, such as strong feelings about one interface or the other. thirty percent of respondents provided an e-mail address to indicate that they would be willing to be contacted for focus groups or further surveys, indicating a high level of interest in the public-facing interfaces the libraries employ. in considering a process for repeating this project, more attention would be paid to methodology to address validity concerns. findings and analysis information technology and libraries | june 2012 24 findings relevant to each research question are discussed here. six hundred twenty-nine surveys contained at least one response—476 for mncat plus and 153 for mncat classic. responses by demographics as shown in table 1, graduate students were the primary respondents for both mncat plus and mncat classic, followed by undergraduates and faculty members. library staff made up 13 percent of mncat classic respondents and 4 percent of mncat plus respondents, although the actual number of library staff responding was nearly identical (twenty-one for mncat plus, twenty for mncat classic). library staff members were disproportionately represented in these survey responses and the group analyzed the results to identify categories in which library staff members differed from overall trends in the responses. questions about affiliation appeared at the end of the surveys, which may account for the high number of respondents in the “unspecified” category. mncat classic respondents frequency mncat plus respondents frequency

comparison of the student survey responses shows that graduate students were overrepresented, while undergraduates were underrepresented, at close to a reverse ratio. of the total number of graduate and undergraduate students, 62 percent of the respondents were graduate students, even though they accounted for only 32 percent in the larger population. conversely, undergraduates represented only 38 percent of the student respondents, even though they accounted for 68 percent of the graduate and undergraduate total. regrettably, the surveys did not include options for identifying oneself as a non-degree-seeking or professional student, so the analysis of students compared with overall population in this section includes only graduate students and undergraduates. differences were also apparent in the representation of all four categories of students within a particular college unit. at least two college units were underrepresented in the survey responses: resource discovery: comparative survey results | hessel and fransen 25 carlson school of management and the college of continuing education. one college unit was overrepresented in the survey results; 59 percent of the overall student respondents to the mncat classic survey, and 47 percent of the mncat plus students indicated that they were housed in the college of liberal arts (cla), and yet cla students only represent 32 percent of the total number of students on campus. table 2 shows the breakdown of percentages by college or unit and the corresponding breakdown by survey respondent, highlighting where significant discrepancies are evident. twin cities overall percentage of students mncat classic student survey respondents +/mncat plus student survey respondents +/ carlson school of management 9% 0%

technology and libraries | june 2012 26 faculty and staff together totaled only eighty-nine respondents on the mncat plus survey and fifty-one respondents on the mncat classic survey. in keeping with graduate and undergraduate student trends, the college of liberal arts (cla) was clearly over-represented in terms of faculty responses. the cla faculty group represents about 17 percent of the faculty at the university of minnesota. yet over half the faculty respondents on the mncat plus survey were from cla; over 80 percent of the mncat classic faculty respondents identified themselves as affiliated with cla. faculty groups that were underrepresented include the medical school and the institute of technology. perceptions of success a critical area of inquiry for the surveys was user satisfaction and perceptions of success: “do users perceive their searching activity as successful?” asked in both surveys, the question’s responses allowed the primo management group to compare respondents’ perceived success between the two interfaces. results show a marked difference: while 86 percent of the mncat classic respondents reported that they are “usually” or “very often” successful at finding what they are looking for, only 62 percent of the mncat plus respondents reported the same perception of success. respondents reported very similar rates of success regardless of school, type of affiliation, or student status. figure 1. perceptions of success: mncat plus and mncat classic these results should be interpreted cautiously. because mncat plus is the libraries’ default catalog interface, mncat classic users are a self-selecting group whose members make a conscious decision to bookmark or click the extra link to use the mncat classic interface. one cannot assume that mncat users in general also would have an 86 percent perception of success were they to use mncat classic; familiarity with the tool could play a part in mncat classic users’ success. 14% 24% 44% 18% 4% 11% 32% 54% 0% 10% 20% 30% 40% 50% 60% rarely sometimes usually very often mncat classic mncat plus resource discovery: comparative survey results | hessel and fransen 27 another possible factor in the reported difference in user success is the higher proportion of known-item searching—finding a book by title—occurring in mncat classic. a user’s criteria for success differ when searching for a known item versus conducting a general topical search. it is easier for a searcher to determine that they have been successful in a situation where they are looking for a specific item. some features of mncat classic, such as the start-of-title and other browse indexes, are well suited to known-item searching and had no direct equivalent in mncat plus, which defaults to relevance-ranked results. (primo version 3 has implemented new features to enhance known-item searching.) comments received from users suggest that several factors played a role. one mncat classic respondent praised the “precision of the search...not just lots of random hits” and noted that mncat classic supports a “[m]ore focused search since i usually already know the title or author.” in contrast, a mncat plus respondent commented that the next-generation interface was “great for browsing topics when you do not have a specific title in mind.” this comment is consonant with the results from other usability testing done on next-generation catalogs. in "next generation catalogs: what do they do and why should we care?", emanuel describes observed differences between topical and known-item searching: “during the testing, users were generally happy with the results when they searched for a broad term, but they were not happy with results for more specific searches because often they had to further limit to find what they wanted in the first screen of results.”4 a common characteristic of next-generation catalogs is that they return a large result set that can then be limited using facets. training and experience may also explain some of the differences in success. mncat plus also enables functionality associated with the functional requirements for bibliographic records (frbr), which is intended to group items with the same core intellectual content in a way that is more intuitive to searchers. however, this feature is unfamiliar to traditional catalog searchers and requires an extra step to discover very specific known-items in primo. one mncat plus user expressed dissatisfaction and added, “i'm not sure if it's my lack of training/practice or that the system is not user-friendly.” in focus group analyses conducted in 2008, oclc found that “when participants conducted general searches on a topic (i.e., searches for unknown items) that they expressed dissatisfaction when items unrelated to what they were looking for were returned in the results list. end users may not understand how to best craft an appropriate search strategy for topic searches.”5 how often do users know the title of the item that they are looking for? users come to the library with different goals in mind. in “chang's browsing,” available in theories of information behavior, chang identified five general browsing themes,6 adapted to discovery by carter.7 for the purposes of the survey, the primo management group grouped those themes into two goals: finding an item when the title is known, and finding anything on a given topic. the primo management group had heard concerns from faculty and staff that they have more difficulty finding an item when they know the title when using mncat plus than they did with mncat classic. the group was interested in knowing how often users search for known items. to explore this topic and its impact on perceptions of success, the surveys included two questions on known-item and topical searching. the survey results shown in table 3 indicate that a significantly higher proportion of mncat classic respondents (30 percent plus 43 percent = 73 percent) than mncat plus respondents (24 information technology and libraries | june 2012 28 percent plus 29 percent = 53 percent) were “very often” or “usually” searching for known items. it may be that users in search of known items have learned to go to mncat classic rather than mncat plus. rarely sometimes usually very often total i already know the title of the item i am looking for mncat classic 7% (11) 19% (29) 30% (46) 43% (66) 152 mncat plus 15% (69) 33% (151) 24% (111) 29% (132) 463 i am looking for any resource relevant to my topic mncat classic 14%

considered how often researchers in different user roles searched for known items versus anything on a topic, clear patterns emerged as shown in figure 2. in the mncat plus survey, only 34 percent of undergraduate mncat plus searchers “usually” or “very often” search for a particular item, versus 74 percent of faculty. conversely, 75 percent of undergraduate respondents “usually” or “very often” search for any resource relevant to a topic, versus 37 percent of faculty. graduate student respondents showed interest in both kinds of use. if successful browsing by topic is best achieved using post-search filtering, it may help to explain differences between undergraduate students and faculty. the analysis of usability testing done on other next generation catalogs described in “next generation catalogs: what do they do and why should we care?” states that “users that did not have extensive searching skills were more likely to appreciate the search first, limit later approach, while faculty members were faster to get frustrated with this technique.”8 results for all mncat classic respondents showed a preference for known item searching, but undergraduate students still indicated that they search more for anything on the topic and less for known items than faculty respondents. no significant differences were identified by discipline. resource discovery: comparative survey results | hessel and fransen 29 figure 2. searching for a known item vs. any relevant resource some qualitative comments from survey takers suggest that respondents view the library interface as a place to go to find something already known to exist, e.g., “i never want to search by topic. library catalogs are for looking up specific items.” however, with respect to discovering resources for a subject in general, both mncat classic and mncat plus respondents showed that they would also like to find items relevant to their topic (figure 2). there was no significant difference between mncat classic and mncat plus respondents on this question; in both environments, only 14 percent of the users said that they would “rarely” be interested in general results relevant to their topic. perceptions of success by specific characteristics for mncat plus, the majority of respondents “somewhat agree” or “strongly agree” that items available online or in a particular collection are easy to find. one-third of the mncat plus respondents had never tried to find an item in a particular format. over 40 percent had never tried to find an item with a particular isbn/issn. interface features may be a factor here: isbn/issn searching is not a choice in the mncat plus drop down menu, so users may not know that they can do such a search. a higher percentage of mncat classic respondents “strongly agree” that it is easy to find items by collection, available online, or in a particular format, than mncat plus respondents. figure 3 shows results based on particular characteristics. information technology and libraries | june 2012 30 figure 3. perception of success by characteristic although the surveys were primarily intended to gather reactions from end users, some interesting data emerged about usage by library staff. as demonstrated in figure 4, library staff respondents were much more likely to have performed the specific types of searches listed in this section than users generally, and reported a much higher rate of perceived success with mncat classic. figure 4. perception of success by characteristic: library staff resource discovery: comparative survey results | hessel and fransen 31 searching by location: local collections and other resources in a large research institution with several physical library locations and many distinct collections, users need the ability to quickly narrow a search to a particular collection. but even the largest institution cannot collect everything a researcher might need. the primo management group wondered not only whether users felt successful when they looked for an item in a particular collection but also wanted to explore whether users want to see items not owned by the institution as part of their search results. finding items among the many library locations was not a problem for either mncat plus or mncat classic respondents: 72 percent either somewhat or strongly agreed that it is easy to find items in a particular collection using mncat. furthermore, survey respondents of both interfaces agreed that they are interested in items no matter where the items are, which underlines the value of a service such as worldcat; 73 percent of mncat plus respondents and 78 percent of mncat classic respondents expressed a preference for seeing items held by other libraries, knowing they could request items using an interlibrary loan service if necessary. preferred search environments three of the survey questions asked users about their preferred search environments for different searching needs:  when looking for a particular book  when looking for a particular journal article  when searching without a particular title in mind each survey presented respondents with a list of choices and space to specify other sources not listed. respondents were encouraged to mark as many sources as they regularly use. when searching for a specific book, users of the two catalog environments identified a number of other sources. the top five sources in each survey are listed in table 4. when i am looking for a specific book, i usually search (check all that apply): mncat classic respondents (frequency) mncat plus respondents (frequency) 1. mncat classic (116) 1. mncat plus (217) 2. worldcat (50) 2. google (165) 3. amazon (50) 3. mncat classic (163) 4. google (49) 4. amazon (160) 5. google books (31) 5. google books (108) table 4. search environment for books information technology and libraries | june 2012 32 qualitative comments indicated that users like being able to connect to amazon and google books in order to look at tables of contents and reviews. they also specifically mentioned barnes and noble, as well as other local libraries. these results show that mncat plus respondents were more likely to also use mncat classic than vice-versa. the data do not suggest why this would be the case, but familiarity with the older interface may play a role. mncat classic respondents were more likely than mncat plus users to return to their search environment when searching for a particular book (82 percent versus 53 percent). one mncat plus respondent commented “i didn't know i could still get to mncat classic.” when searching for a specific journal article, users of both systems chose “other databases (jstor, pubmed, etc.)” above all the other choices. even more respondents would likely have marked this choice if not for confusion over the term “other databases.” most of the comments mentioned specific databases, even when the respondent had not selected the “other databases” choice. one user commented, “most of these choices would be illogical. you don't list article indexes, that's where i go first.” table 5 lists the five responses marked most often for each survey. when i am looking for a specific journal article, i usually search (check all that apply): mncat classic respondents (frequency) mncat plus respondents (frequency) 1. other databases (jstor, pubmed, etc.) (92) 1. other databases (jstor, pubmed, etc.) (232) 2. mncat classic (53) 2. google scholar (131) 3. google scholar (40) 3. e-journals list (130) 4. e-journals list (34) 4. mncat plus (110) 5. google (29) 5. mncat plus article search (101) table 5. search environment for articles. qualitative comments from respondents indicated that interfaces would be more useful if they helped users find online journal articles. this raised some questions with regard to mncat plus, which includes a tab labeled “articles” for conducting federated article searches. however, mncat plus respondents noted that they used the plus “articles” search almost as much as they did mncat plus. other plus comments included: i tried to use this for journal articles but it only has some in the database i guess and when i did my search it only found books and no articles. i don't understand it. i tried this new one and it came up with wierd [sic] stuff in terms of articles. my professor said to give up and use the regular indexes because i wasn't getting what i needed to do the paper. it wasted my time. this desire for federated search coupled with the expressions of dissatisfaction with the existing federated search platform is consistent with the mixed opinions expressed in other studies, such as sam houston state university’s assessment of use of and satisfaction with the webfeat resource discovery: comparative survey results | hessel and fransen 33 federated search tool. that study found “[f]ederated search use was highest among lower-level undergraduates, and both use and satisfaction declined as student classification rose.”9 the new search tools that contain preindexed articles, such as primo central, summon, worldcat local, and ebsco discovery service, may address the frustrations that more experienced searchers express regarding federated search technology. when researching a topic without a specific title in mind, “google” and “other databases” were nearly equal and ranked first for mncat plus respondents, while “other databases” ranked first for mncat classic respondents. table 6 lists the five responses marked most option for each survey. when i am researching a topic without a specific title in mind, i usually search (check all that apply): mncat classic respondents (frequency) mncat plus respondents (frequency) 1. other databases (jstor, pubmed, etc.) (84) 1. google (197) 2. mncat classic (76) 2. other databases (jstor, pubmed, etc.) (192) 3. google (63) 3. google scholar (155) 4. google scholar (47) 4. mncat plus (145) 5. worldcat (32) 5. mncat classic (101) table 6. search environment for topics significant differences based on school affiliation were evident in the area of preferred search environments for topical research. for example, institute of technology respondents reported using google much more often when researching without a specific title in mind than respondents in other areas. evidence from the health sciences is limited in that only seven percent of respondents in total identified themselves as being from this area. however, these limited results show that health sciences respondents relied more on library databases than on google. respondents in the liberal arts relied more on mncat, in either version, than did respondents in the other fields. desired resource types one feature of the primo discovery interface is its ability to aggregate records from more than one source. university libraries maintains several internal data sources that are not included in the catalog, and the possibility of including some of these in the mncat plus catalog has been considered many times since primo’s release. the primo management group was interested to hear from users whether they would find three types of internal sources useful: research reports and preprints, online media, and archival finding aids. the group also asked users to mark “online journal articles” if they would find article results helpful. the question did not specify whether journal articles would appear integrated with other search results in a mncat “books” search or information technology and libraries | june 2012 34 in a separate search such as that already provided through a metasearch on the mncat plus articles tab. the surveys asked users what kinds of resources would make mncat more useful. the results for both mncat plus and mncat classic were similar and response counts for both surveys were ordered as shown in table 7. respondents could mark more than one of the choices. i would find mncat more useful if it helped me find: mncat classic frequency mncat plus frequency online journal articles 65 255 u of m research materials (e.g., research reports, preprints) 34 149 online media (e.g., digital images, streaming audio/visual) 27 134 archival finding aids 27 90 table 7. desired resource types the primo management group noted that more mncat plus respondents chose “online journal articles” more frequently than the other categories even though the mncat plus interface includes an “articles” tab for federated searching. it is unclear whether the respondents were not seeing the “articles” tab in mncat plus because they would like to see search results integrated, or if they were using the “articles” tab and were not satisfied with the results. comments from respondents generally supported the inclusion of a wider range of resources in mncat. however, several respondents also expressed concerns about the trade-offs that might be involved in providing wider coverage. one user liked the idea of having the databases “all … in one place,” but added that “it would have to just give you the stuff that you need.” several users cited the varying quality of the material discovered through library sources. one user supported the inclusion of articles “if it included good articles and not the ones i got.” a mncat classic respondent gave the variable quality of the material he or she had found through a database search as a reason for leaving the coverage of mncat as it is: “i use the best sources depending on my needs.” another mncat classic user expressed doubt that coverage of all disciplines was feasible. in commenting on the content of mncat, respondents also mentioned specific types of material that they wanted to see (e.g. archives of various countries), as well as difficulties with particular classes of material (“the confusing world of government documents”). one mncat plus user related his or her interest in public domain items to a specific item of functionality that would enhance their discovery, namely a date sort. in general, the interest in university of minnesota research material was fairly high. however, faculty members ranked university of minnesota research materials last in terms of preference: only twelve faculty respondents chose the option, out of sixty-one total faculty respondents. resource discovery: comparative survey results | hessel and fransen 35 conclusions the data from two surveys, conducted concurrently in 2009 on a traditional opac (mncat classic) and next-generation catalog (mncat plus), point to differences in the use and perceptions of both systems. there appeared to be fairly strong “brand loyalty” with mncat classic, given that this interface is no longer the default search for the libraries. surveys for both systems suggest a perception of success that is lower than desirable and that there is room to improve the quality of the discovery experience. it is unclear from the data if the reported perceptions of success were the result of the systems not finding what the user wants, or if the systems did not contain what the user wanted to find. mncat classic respondents were more likely to use worldcat to find a specific book than mncat plus respondents. mncat plus respondents indicated a use of mncat classic, but not vice versa. both sets of surveys described use of amazon and google for discovery. mncat plus respondents reported lower rates of success at finding known items than mncat classic respondents. mncat classic respondents were far more likely to have a specific title in mind that they wanted to obtain; half of the mncat plus respondents reported having a specific title in mind. the team that examined the survey responses found that the data suggested several key attributes that should be present in the libraries discovery environment. further discussion of the results and suggested attributes was conducted with library staff members in open sessions. results also informed local work on improving discovery interfaces. the results suggested:  the environment should support multiple discovery tasks, including known-item searching and topical research.  support for discovery activity should be provided to all primary constituent groups, noting the significant survey response by graduate student searchers.  users want to discover materials that are not owned by the libraries, in addition to local holdings.  a discovery environment should make it easy for users to find and access resources in vendor-provided resources, such as jstor and pubmed. while the results of the 2009 surveys provided a valuable description of usage, the survey team recognized that methodological choices limit the usefulness in applying results to a larger population. the team also recognized that there were a number of questions yet unanswered. some of these outstanding questions present opportunities for future research and suggest that a variety of formats might be useful, including surveys, focus groups, and targeted interviews.  to what extent do users expect to find integrated search results among different kinds of content, such as articles, databases, indexes, and even large scale data sets?  what general search strategies do users use to navigate the complex discovery environment that is available to them, and where are the failure points?  how much of the current environment requires training and how much is truly intuitive to users? information technology and libraries | june 2012 36  how can the university libraries identify and serve users who did not complete the surveys?  how useful would users find targeted results based on a particular characteristic such as role, student status, or discipline? since the surveys were conducted, the university libraries upgraded to primo version 3, which included features to address some of the concerns respondents identified in the surveys, such as known-item searching. primo version 3 allows users to conduct a left-justified title search (“title begins with…”), as well as sort by fields such as title and author. once the new version has been in place long enough for users to develop some comfort with the interface, the primo management group intends to resolve methodological issues and repeat its surveys, measuring users’ reactions against the baseline data set in the 2009 surveys. acknowledgements we would like to thank the other members of the primo management group, who helped to design and implement the surveys, as well as analyze and communicate the results: chew chiat naun (chair), susan gangl, connie hendrick, lois hendrickson, kristen mastel, r. arvid nelsen, and jeff peterson. we also want to acknowledge the helpful feedback and guidance of the group’s sponsor, john butler. references 1 tamar sadeh, “user experience in the library: a case study.” new library world 109, no. 1/2 (2008): 7–24. 2 cody hanson et al.,

academic library jody condit fagan meris mandernach carl s. nelson jonathan r. paulo grover saunders information technology and libraries | march 2012 83 abstract discovery tools are emerging in libraries. these tools offer library patrons the ability to concurrently search the library catalog and journal articles. while vendors rush to provide feature-rich interfaces and access to as much content as possible, librarians wonder about the usefulness of these tools to library patrons. to learn about both the utility and usability of ebsco discovery service, james madison university (jmu) conducted a usability test with eight students and two faculty members. the test consisted of nine tasks focused on common patron requests or related to the utility of specific discovery tool features. software recorded participants’ actions and time on task, human observers judged the success of each task, and a post–survey questionnaire gathered qualitative feedback and comments from the participants. participants were successful at most tasks, but specific usability problems suggested some interface changes for both ebsco discovery service and jmu’s customizations of the tool. the study also raised several questions for libraries above and beyond any specific discovery-tool interface, including the scope and purpose of a discovery tool versus other library systems, working with the large result sets made possible by discovery tools, and navigation between the tool and other library services and resources. this article will be of interest to those who are investigating discovery tools, selecting products, integrating discovery tools into a library web presence, or performing evaluations of similar systems. introduction discovery tools appeared on the library scene shortly after the arrival of next-generation catalogs. the authors of this paper define discovery tools as web software that searches journal-article and library-catalog metadata in a unified index and presents search results in a single interface. this differs from federated search software, which searches multiple databases and aggregates the results. examples of discovery tools include serials solutions summon, ebsco discovery service, jody condit fagan (faganjc@jmu.edu) is director, scholarly content systems, meris mandernach (manderma@jmu.edu) is collection management librarian, carl s. nelson (nelsoncs@jmu.edu) is digital user experience specialist, jonathan r. paulo (paulojr@jmu.edu) is education librarian, and grover saunders (saundebn@jmu.edu) is web media developer, carrier library, james madison university, harrisonburg, va. mailto:faganjc@jmu.edu mailto:manderma@jmu.edu mailto:nelsoncs@jmu.edu mailto:paulojr@jmu.edu mailto:saundebn@jmu.edu usability test results for a discovery tool in an academic library | fagan et al 84 ex libris primo, and oclc worldcat local; examples of federated search software include serials solutions webfeat and ebsco integrated search. with federated search software, results rely on the search algorithm and relevance ranking as well as each tool’s algorithms and relevance rankings. discovery tools, which import metadata into one index, apply one set of search algorithms to retrieve and rank results. this difference is important because it contributes to a fundamentally different user experience in terms of speed, relevance, and ability to interact consistently with results. combining the library catalog, article indexes, and other source types in a unified interface is a big change for users because they no longer need to choose a specific search tool to begin their search. research has shown that such a choice has long been in conflict with users’ expectati ons.1 federated search software was unable to completely fulfill users’ expectations because of its limited technology.2 now that discovery tools provide a truly integrated search experience, with greatly improved relevance rankings, response times, and increased consistency, libraries can finally begin to meet this area of user expectation. however, discovery tools present new challenges for users: will they be able to differentiate between source types in the integrated results sets? will they be able to limit large results sets effectively? do they understand the scope of the tool and that other online resources exist outside the tool’s boundaries? the sea change brought by discovery tools also raises challenges for librarians, who have grown comfortable with the separation between the library catalog and other online databases. discovery tools may mask important differences between disciplinary searching, and they do not currently offer discipline-specific strategies or limits. they also lack authority control, which makes topical precision a challenge. their usual prominence on library websites may direct traffic away from carefully cultivated and organized collections of online resources. discovery tools offer both opportunities and challenges for library instruction, depending on the academic discipline, users’ knowledge, and information-seeking need. james madison university (jmu) is a predominantly undergraduate institution of approximately 18,000 students in virginia. jmu has a strong information literacy program integrated into the curriculum through the university’s information seeking skills test (isst). the isst is completed before students are able to register for third-semester courses. additionally, the library provides an information literacy tutorial, “go for the gold,” that supports the skills needed for the isst. jmu launched ebsco discovery service (eds) in august 2010 after participating as a beta development partner in spring and summer 2010. as with other discovery tools, the predominant feature of eds is integration of the library catalog with article databases and other types of sources. at the time of this study, eds had a few differentiating features. first, because of ebsco’s business as a database and journal provider, article metadata was drawn from a combination of journal-publisher information and abstracts and index records. the latter included robust subject indexing (e.g., the medical subject headings in cinahl). the content searched by eds varies by information technology and libraries | march 2012 85 institution according to the institution’s subscription. jmu had a large number of ebsco databases and third-party database subscriptions through ebsco, so the quantity of information searched by eds at jmu is quite large. eds also allowed for extensive customization of the tool, including header navigation links, results-screen layout, and the inclusion of widgets in the right-hand column of the results screen. jmu libraries developed a custom “quick search” widget based on eds for the library home page (see figure 1), which allows users to add limits to the discovery-tool search and assists with local authentication requirements. based on experience with a pilot test of the open-source vufind next-generation catalog, jmu libraries believed users would find the ability to limit up-front useful, so quick search’s first drop-down menu contained keyword, title, and author field limits; the second drop-down contained limits for books, articles, scholarly articles, “just leo library catalog,” and the library website (which did not use eds). the “just leo library catalog” option limited the user’s search to the library catalog database records but used the eds interface to perform the search. to access the native catalog interface, a link to leo library catalog was included immediately above the search box as well as in the library website header. figure 1. quick search widget on jmu library homepage usability test results for a discovery tool in an academic library | fagan et al 86 evaluation was included as part of the implementation process for the discovery t ool, and therefore a usability test was conducted in october 2010. the purpose of the study was to explore how patrons used the discovery tool, to uncover any usability issues with the chosen system and to investigate user satisfaction. specific tasks addressed the use of facets within the discovery tool, patrons’ use of date limiters, and the usability of the quick search widget. the usability test also had tasks in which users were asked to locate books and articles using only the discovery tool, then repeat the task using anything but the discovery tool. this article interprets the usability study’s results in the context of other local usability tests and web-usage data from the first semester of use. some findings were used to implement changes to quick search and the library website, and to recommend changes to ebsco; however, other findings suggested general questions related to discovery tool software that libraries will need to investigate further. literature review literature reviewed for this article included some background reading on users and library catalogs, library responses to users’ expectations, usability studies in libraries, and usability studies of discovery tools specifically. the first group of articles comprised a discussion about the limitations of traditional library catalogs. the strengths and weaknesses of library catalogs were reported in several academic libraries’ usability studies.3 calhoun recognized that library users’ preference for google caused a decline in the use and value of library catalogs, and encouraged library leaders to “establish the catalog within the framework of online information discovery systems.” 4 this awareness of changes in user expectations during a time when google set the benchmark for search simplicity was echoed by numerous authors who recognized the limits of library catalogs and expressed a need for the catalog to be greatly modernized to keep pace with the evolution of the web. 5 libraries have responded in several ways to the call for modernization, most notably through investigations related to federated searching and next-generation catalogs. several articles have presented usability studies results for various federated searching products.6 fagan provided a thorough literature review of faceted browsing and next-generation catalogs.7 western michigan university presented usability study results for the next-generation catalog vufind, revealing that participants took advantage of the simple search box but did not use the next-generation catalog features of tagging, comments, favorites, and sms texting. 8 the university of minnesota conducted two usability studies of primo and reported that participants were satisfied with using primo to find known print items, limit by author and date, and find a journal title.9 tod olson conducted a study with graduate students and faculty using the aquabrowser interface, and his participants located sources for their research they had not previously been able to find.10 information technology and libraries | march 2012 87 the literature also revealed both opportunities and limitations of federated searching and nextgeneration catalogs. allison presented statistics from google analytics for an implementation of encore at the university of nebraska-lincoln. 11 the usage statistics revealed an increased use of article databases as well as an increased use of narrowing facets such as format and media type, and library location. allison concluded that encore increased users’ exposure to the entire collection. breeding concluded that federated searching had various limitations, especially search speed and interface design, and was thus unable to compete with google scholar. 12 usability studies of next-generation catalogs revealed a lack of features necessary to fully incorporate an entire library’s collection. breeding also recognized the limitations of next-generation library catalogs and saw discovery tools as their next step in evolution: “it’s all about helping users discover library content in all formats, regardless of whether it resides within the physical library or among its collections of electronic content, spanning both locally owned materials and those accessed remotely through subscriptions.” 13 the dominant literature related to discovery tools discussed features,14 reviewed them from a library selector perspective,15 summarized academic libraries’ decisions following selection, 16 presented questions related to evaluation after selection,17 and offered a thorough evaluation of common features.18 allison concluded that “usability testing will help clarify what aspects need improvement, what additions will make [the interface] more useful, and how the interface can be made so intuitive that user training is not needed.”19 breeding noted “it will only be through the experience of library users that these products will either prove themselves or not.”20 libraries have been adapting techniques from the field of usability testing for over a decade to learn more about user behavior, usability, and user satisfaction, with library web sites and systems. 21 rubin and chisnell and dumas and redish provided an authoritative overview of the benefits and best practices of usability testing. 22 in addition, campbell and norlin and winters offered specific usability methodologies for libraries.23 worldcat local has dominated usability studies of discovery tools published to date. ward, shadle, and mofield conducted a usability study at the university of washington. 24 although the second round of testing was not published, the first round involved seven undergraduate and three graduate students; its purpose “was to determine how successful uw students would be in using worldcat local to discover and obtain books and journal articles (in both print and electronic form) from the uw collection, from the summit consortium, and from other worldcat libraries.” 25 although participants were successful at completing these tasks, a few issues arose out of the usability study. users had difficulty with the brief item display because reviews were listed higher than the actual items. the detailed item display also hindered users’ ability to decipher between various editions and formats. the second round of usability testing, not yet published, included tasks related to finding materials on specific subject areas. usability test results for a discovery tool in an academic library | fagan et al 88 boock, chadwell, and reese conducted a usability study of worldcat local at oregon state university.26 the study included four tasks and five evaluative questions. forty undergraduate students, sixteen graduate students, twenty-four library employees, four instructors, and eighteen faculty members took part in the study. they summarized that users found known-title searching to be easier in the library catalog but found topical searches to be more effective in worldcat local.the participants preferred worldcat local for the ability to find articles and search for materials in other institutions. western washington university also conducted a usability study of worldcat local. they selected twenty-four participants with a wide range of academic experience to conduct twenty tasks in both worldcat local and the traditional library catalog.27 the comparison revealed several problems in using worldcat local, including users’ inability to determine the scope of the content, confusion over the intermixing of formats, problems with the display of facet option, and difficulty with known-item searches. western washington university decided not to implement worldcat local. oclc published a thorough summary of several usability studies conducted mostly with academic libraries piloting the tool, including the university of washington; the university of california (berkeley, davis, and irvine campuses); ohio state university; the peninsula library system in san mateo, california; and the free library of urbana and the des plaines public library, both in illinois.28 the report conveyed favorable user interest in searching local, group, and global collections together. users also appreciated the ability to search articles and books together. the authors commented, “however, most academic participants in one test (nine of fourteen) wrongly assumed that journal article coverage includes all the licensed content available at their campuses.”29 oclc used the testing results to improve the order of search results, provide clarity about various editions, improve facets for narrowing a search, provide links to electronic resources, and increase visibility of search terms. at grand valley state university, doug way conducted an analysis of usage statistics after implementing the discovery tool summon in 2009; the usage statistics revealed an increased use of full-text downloads and link resolver software but a decrease in the use of core subject databases.30 the usage statistics showed promising results, but way recommended further studies of usage statistics over a longer period of time to better understand how discovery tools affect entire library collections. north carolina state university libraries released a final report about their usability study of summon.31 the results of these usability studies were similar to other studies of discovery tools: users were satisfied with the ability to search the library catalog and article databases with a single search, but users had mixed results with known-item searching and confusion about narrowing facets and results ranking. although several additional academic libraries have conducted usability studies of encore, summon, and ebsco discovery service, the results have not yet been published.32 information technology and libraries | march 2012 89 only one usability study of ebsco discovery service was found. in a study with six participants, williams and foster found users were satisfied and able to adapt to the new system quickly but did not take full advantage of the rich feature set.33 combined with the rapid changes in these tools, the literature illustrates a current need for more usability studies related to discovery tools. the necessary focus on specific software implementations and different study designs make it difficult to identify common themes. additional usability studies will offer greater breadth and depth to the current dialogue about discovery tools. this article will help fill the gap by presenting results from a usability study of ebsco discovery service. publishing such usability results of discovery tools will inform institutional decisions, improve user experiences, and advance the tools’ content, features, and interface design. in addition, libraries will be able to more thoroughly modernize library catalogs to meet users’ changing needs and expectations as well as keep pace with the evolution of the web. method james madison university libraries’ usability lab features one workstation with two pieces of usability software: techsmith’s morae (version 3) (http://www.techsmith.com/morae.asp), which records screen captures of participant actions during the usability studies, and the usability testing environment (ute) (version 3), which presents participants with tasks in a web-browser environment. the ute also presents end-of-task questions to measure time on task and task success. the study of eds, conducted in october 2010, was covered by an institutional review board – approved protocol. participants were recruited for the study through a bulk email sent to all students and faculty. interested respondents were randomly selected to include a variety of grade levels and majors for students and years of service and disciplines taught for faculty members. the study included ten participants with ranging levels of experience: two freshman, two sophomores, two juniors, one senior, one graduate student, and two faculty members. three of the participants were from the school of business, one from education, two from the arts and humanities, and two from the sciences. the remaining two participants had dual majors in the humanities and the sciences. a usability rule of thumb is that at least five users will reveal more than 75 percent of usability issues.34 because the goal was to observe a wide range of user behaviors and usability issues, and to gather data about satisfaction from a variety of perspectives, this study used two users of each grade level plus two faculty participants (for a total of ten) to provide as much heterogeneity as possible. student participants were presented with ten pre–study questions, and faculty participants were asked nine pre–study questions (see appendix a). the pre–study questions were intended to http://www.techsmith.com/morae.asp usability test results for a discovery tool in an academic library | fagan et al 90 gather information about participants’ background, including their time at jmu, their academic discipline, and their experience with the library website, the ebscohost interface, the library catalog, and library instruction. since participants were anonymous, we hoped their answers would help us interpret unusual comments or findings. pre–test results were not used to form comparison groups (e.g., freshmen versus senior) because these groups would not be representative of their larger populations. these questions were followed by a practice task to help familiarize participants with the testing software. the study consisted of nine tasks designed to showcase usability issues, show the researchers how users behaved in the system, and measure user satisfaction. appendix b lists the tasks and what they were intended to measure. in designing the test, determining success on some tasks seemed very objective (find a video about a given topic) while others appeared to be more subjective (those involving relevance judgments). for this reason, we asked participants to provide satisfaction information on some tasks and not others. in retrospect, for consistency of interpretation, we probably should have asked participants to rate or comment on every task. all of the tasks were presented in the same order. tasks were completed either by clicking “answer” and answering a question (multiple choice or typed response), or by clicking “finished” after navigating to a particular webpage. participants also had the option to skip the task they were working on and move to the next task. allowing participants to skip a task helps differentiate between genuinely incorrect answers and incorrect answers due to participant frustration or guessing. a time limit of 5 minutes was set for tasks 1–7, while tasks 8 and 9 were given time limits of 8 minutes, after which the participant was timed out. time limits were used to ensure participants were able to complete all tasks within the agreed-upon session. average time on task across all tasks was 1 minute, 35 seconds. after the study was completed, participants were presented with the system usability scale (sus), a ten-item scale using statements of subjective assessment and covering a variety of aspects of system usability.35 sus scores, which provide a numerical score out of 100, are affected by the complexity of both the system and the tasks users may have performed before taking the sus. the sus was followed by a post–test consisting of six open-ended questions, plus one additional question for faculty participants, intended to gather more qualitative feedback about user satisfaction with the system (see appendix a). a technical glitch with the ute software affected the study in two ways. first, on seven of the ninety tasks, the ute failed to enforce the five-minute maximum time limit, and participants exceeding a task’s time limit were allowed to continue the task until they completed or skipped the task. one participant exceeded the time limit on task 1 while three of these errors occurred during both tasks 8 and 9. this problem potentially limits the ability to compare the average time on task across tasks; however, since this study used time on task in a descriptive rather than comparative way, the impact on interpreting results is minimal. the seven instances in which the glitch occurred were included in the average time on task data found in figure 3 because the times information technology and libraries | march 2012 91 were not extreme and the time limit had been imposed mostly to be sure participants had time to complete all the tasks. a second problem with the ute was that it randomly and prematurely aborted some users’ tasks; when this happened, participants were informed that their time had run out and were then moved on to the next task. this problem is more serious because it is unknown how much more time or effort the participant would have spent on the task or whether they would have been more successful. because of this, the results below specify how many participants were affected for each task. although this was unfortunate, the results of the participants who did not experience this problem still provide useful cases of user behavior, especially because this study does not attempt to generalize observed behavior or usability issues to the larger population. although a participant mentioned a few technical glitches during testing to the facilitator, the extent of software errors was not discovered until after the tests were complete (and the semester was over) because the facilitator did not directly observe participants during sessions. results the participants were asked several pre–test questions to learn about their research habits. all but one participant indicated they used the library website no more than six times per month (see figure 2). common tasks this study’s student participants said they performed on the website were searching for books and articles, searching for music scores, “research using databases,” and checking library hours. the two faculty participants mentioned book and database searches, electronic journal access, and interlibrary loan. participants were shown the quick search widget and were asked “how much of the library’s resources do you think the quick search will search?” seven participants said “most”; only one person, a faculty member, said it would search “all” the library’s resources. figure 2. monthly visits to library website < 1 visit (2) 1 3 visits (4) 4 6 visits (3) > 7 visits (1) usability test results for a discovery tool in an academic library | fagan et al 92 when shown screenshots of the library catalog and an ebscohost database, seven participants were sure they had used leo library catalog, and three were not sure. three indicated that they had used an ebsco database before, five had not, and two were not su re. participants were also asked how often they had used library resources for assignments in their major field of study; four said “often,” two said “sometimes,” one “rarely/never,” and one “very often.” students were also asked “has a librarian spoken to a class you’ve attended about library research?” and two said yes, five said no, and one was not sure. a “practice task” was administered to ensure participants were comfortable with the workstation and software: “use quick search to search a topic relating to your major/discipline or another topic of interest to you. if you were writing a paper on this topic how satisfied would you be with these results?” no one selected “no opinion” or very unsatisfied”; sixty percent were “very satisfied” or “satisfied” with their results; forty percent were “somewhat unsatisfied.” figure 3 shows the time spent on each task, while figure 4 describes participants’ success

minutes; however one faculty participant took more than 12 minutes on this task; if his or her time was removed, the time on task average was 1 minute, 23 seconds. figure 5 shows the participants’

figure 5. participants’ search terms and comments information technology and libraries | march 2012 95 the second task started on the library homepage and asked participants to find a video related to early childhood cognitive development. this task was chosen because jmu libraries have significant video collections and because the research team hypothesized users might have trouble because there was no explicit way to limit to videos at the time. the average time on this task was two minutes, with one person experiencing an arbitrary time out by the software. participants were judged to be successful on this task by the researchers if they found any video related to the topic. all participants were successful on this task, but four entered, then left the discovery tool interface to complete the task. five participants looked for a video search option in the drop-down menu, and of these, three immediately used something other than quick search when they saw that there was no video search option. of those who tried quick search, six opened the source type facet in eds search results and four selected a source type limit, but only two selected a source type that led directly to success (“non-print resources”). task 3 started participants in eds (see figure 6) and asked them to search on speech pathology, find a way to limit search results to audiology, and limit their search results to peer-reviewed sources. participants spent an average of 1 minute, 40 seconds on this task, with five participants being artificially timed out by the software. participants’ success on this task was determined by the researchers’ examination of the number of subtasks they completed. the three subtasks consisted of successfully searching for the given topic (speech language pathology) limiting the search results to audiology, and further limiting the results to peer reviewed sources. four participants were able to complete all three subtasks, including two who were timed out. (the times for those who were timed out were not included in time on task averages, but they were given credit for success.) five completed just two of the subtasks, failing to limit to peerreviewed; one of these because of a timeout. it was unclear why the remaining participants did not attempt to alter the search results to “peer reviewed.” looking at the performed actions, six of the ten typed “and audiology” into search keywords to narrow the search results, while one found and used “audiology” in the subject facet on the search results page. six participants found and used the “scholarly (peer reviewed) journals” checkbox limiter. usability test results for a discovery tool in an academic library | fagan et al 96 figure 6. ebsco discovery service interface beginning with the results they had from task 3, task 4 asked participants to find more recent sources and to select the most recent source available. task success was measured by correct completion of two subtasks: limiting the search results to the last five years and finding the most recent source. the average time on task was 1 minute, 14 seconds, with three artificial timeouts. of those who did not time out, all seven were able to limit their sources to be more recent in some way, but only three were able to select the most recent source. in addition to this being a common research task, the team was interested to see how users accomplished this task. three typed in the limiter in the left-hand column, two typed in the limiter on the advanced search screen, and two used the date slider. two participants used the “sort” drop-down menu to change the sort order to “date descending,” which helped them complete this task. other participants changed the dates, and then selected the first result, which was not the most recent. task 5, which started within eds, asked participants to find a way to ask a jmu librarian for help. the success of this task was measured by whether they reached the correct url for the ask-a information technology and libraries | march 2012 97 librarian page; eight of the ten participants were successful. this task took an average of only 31 seconds to complete, and eight of the ten used the ask-a-librarian link at the top of the page. of the two unsuccessful participants, one was timed out, while another clicked “search modes” for no apparent reason, then clicked back and decided to finish the task. task 6 started in the eds interface and asked participants to locate the journal yachting and boating world and select the correct coverage dates and online status from a list of four options; participants were deemed successful at two subtasks if they selected the correct option and successful at one subtask if they chose an option that was partially correct. participants took an average of two minutes on this task; only five answered correctly. during this task, three participants used the ebsco search option “so journal title/source,” four used quotation marks, and four searched or re-searched with the “title” drop-down menu option. three chose the correct dates of coverage, but were unable to correctly identify the online availability. it is important to note that only searching and locating the journal title were accomplished with the discovery tool; to see dates of coverage and online availability, users clicked jmu’s link resolver button, and the resulting screen was served from serials solutions’ article linker product. although some users spent more time than perhaps was necessary using the eds search options to locate the journal, the real barriers to this task were encountered when trying to interpret the serials solutions screen. task 7, where participants started in eds, was designed to determine whether users could navigate to a research database outside of eds. users were asked to look up the sculpture genius of mirth and were told the library database camio would be the best place to search. they were instructed to “locate this database and find the sculpture.” the researcher observed the recordings to determine success on this task, which was defined as using camio to find the sculpture. participants took an average of 1 minute, 32 seconds on this task; seven were observed to complete the task successfully, while three chose to skip the task. to accomplish this task, seven participants used the jmu research databases link in the header navigation at some point, but only four began the task by doing this. six participants began by searching within eds. the final two tasks started on the library homepage and were a pair: participants were asked to find two books and two recent, peer-reviewed articles (from the last five years) on rheumatoid arthritis. task 8 asked them to use the library’s eds widget, quick search, to accomplish this, and task 9 asked them to accomplish the same task without using quick search. when they found sources, they were asked to enter the four relevant titles in a text-entry box. the average time spent on these tasks was similar: about four minutes per task. comparing these tasks was somewhat confusing because some participants did not follow instructions. user s uccess was determined by the researchers’ observation of how many of the four subtasks the user was able to complete successfully: find two books, find two articles, limit to peer reviewed, and select articles from last five years (with or without using a limiter); figure 4 shows their success. usability test results for a discovery tool in an academic library | fagan et al 98 looking at the seven users who used quick search on the quick search tasks, six limited to “scholarly (peer reviewed) journals”; six limited to the last five years; and seven narrowed results using the source type facet. the average number of subtasks completed on task eight was 3.14 out of 4. looking at the seven users who followed instructions and did not use quick search on task 9, all began with the library catalog and tried to locate articles within the library catalog. the average number of subtasks completed on task 9 was 2.29 out of 4. some users tried to locate articles by setting the catalog’s material type drop-down menu to “periodicals” and others used the catalog’s “periodical” tab, which performed a title keyword search of the e-journal portal. for task 9, only two users eventually chose a research database to find articles. user behavior can only be compared for the six users (all students) who followed instructions on both tasks; a summary is provided in figure 4. after completing all nine tasks, participants were presented with the system usability scale. eds scored 56 out of 100. following the sus, participants were asked a series of post–test questions. only one of the faculty members chose to answer the post–test questions. when asked how they would use quick search, all eight students explicitly mentioned class assignments, and the participating faculty member replied “to search for books.” two students mentioned books specifically, while the rest used the more generic term “sources” to describe items for which they would search. when asked “when would you not use this search tool?” the faculty member said “i would just have to get used to using it. i mainly go to [the library catalog] and then research databases.” responses from the six students who answered this question were vague and hard to categorize: • “not really sure for more general question/learning” • “when just browsing” • “for quick answers” • “if i could look up the information on the internet” • “when the material i need is broad” • “basic searching when you do not need to say where you got the info from” when asked for the advantages of quick search, four specifically mentioned the ability to narrow results, three respondents mentioned “speed,” three mentioned ease of use, and three mentioned relevance in some way (e.g., “it does a pretty good job associating keywords with sources”). two mentioned the broad coverage and one compared it to google, “which is what students are looking for.” when asked to list disadvantages, the faculty member mentioned he/she was not sure what part of the library home page was actually “quick search,” and was not sure how to get to his/her library account. three students talked about quick search being “overwhelming” or “confusing” because of the many features, although one of these also stated, “like anything you need to learn in order to use it efficiently.” one student mentioned the lack of an audio recording limit and another said “when the search results come up it is hard to tell if they are usable results.” information technology and libraries | march 2012 99 knowing that quick search may not always provide the best results, the research team also asked users what they would do if they were unable to find an item using quick search. a faculty participant said he or she would log into the library catalog and start from there. five students mentioned consulting a library staff member in some fashion. three mentioned moving on from library resources, although not necessarily as their first step. one said “find out more information on it to help narrow down my search.” only one student mentioned the library catalog or any other specific library resource. when participants were asked if “quick search” was an appropriate name, seven agreed that it was. of those who did not agree, one participant’s comment was “not really, though i don’t think it matters.” and another’s was “i think it represents the idea of the search, but not the action. it could be quicker.” the only alternative name suggestion was “search tool.” web traffic analysis web traffic through quick search and in eds provides additional context for this study’s results. during august–december 2010, quick search was searched 81,841 times from the library homepage. this is an increase from traffic into the previous widget in this location that searched the catalog, which received 41,740 searches during the same period in 2009. even adjusting for an approximately 22 percent increase in website traffic from 2009 to 2010, this is an increase of 75 percent. interestingly, the traffic to the most popular link on the library homepage, research databases, went from 55,891 in 2009 to 30,616 in 2010, a decrease of 55 percent when adjusting for the change in website traffic. during fall 2010, 28 percent of quick search searches from the homepage were executed using at least one drop-down menu. twelve percent changed quick search’s first drop-down menu to something other than the keyword default, with “title” being the most popular option (7 percent of searches) followed by author (4 percent of searches). twenty percent of users changed the second drop-down option; “just articles” and “just books” were the most popular options, garnering 7 percent and 6 percent of searches, respectively, followed by “just scholarly articles,” which accounted for 4 percent of searches. looking at ebsco’s statistical reports for jmu’s implementation of eds, there were 85,835 sessions and approximately 195,400 searches during august–december 2010. this means about 95 percent of eds sessions were launched using quick search from the homepage. there were an average of 2.3 searches per session, which is comparable to past behavior in jmu’s other ebscohost databases. discussion usability test results for a discovery tool in an academic library | fagan et al 100 the goal of this study was to gather initial data about user behavior, usability issues, and user satisfaction with discovery tools. the task design and technical limitations of the study mean that comparing time on task between participants or tasks would not be particularly illuminating; and, while the success rates on tasks are interesting, they are not generalizable to the larger jmu population. instead, this study provided observations of user behavior that librarians can use to improve services, it suggested some “quick fixes” to usability issues, and it pointed to several research questions. when possible, these observations are supplemented by comparisons between this study and the only other published usability study of eds.36 this study confirmed a previous finding of user studies of federated search software and discovery tools: students have trouble determining what is searched by various systems.37 on the tasks in which they were asked to not use quick search to find articles, participants tried to search for articles in the library catalog. although all but one of this study’s participants correctly answered that quick search did not search “all” library resources, seven thought it searched “most.” both “most” or “some” would be considered correct; however, it is interesting that answering this question more specifically is challenging even for librarians. many journals in subject article indexes and abstracts are included in the eds foundation index; furthermore, jmu’s implementation of eds includes all of jmu’s ebsco subscription resources as well, making it impractical to assemble a master list of indexed titles. of course, there are numerous online resources with contents which may never be included in a discovery tool, such as political voting records, ethnographic files, and financial data. users often have access to these resources through their library. however, if they do not know the library has a database of financial data, they will certainly not consider this content in their response to a question of how many of the library resources are included in the discovery tool. as discovery tools begin to fulfill users’ expectations for a “single search,” libraries will need to share best practices for showcasing valuable, useful collections that fall outside the discovery tool’s scope or abilities. this is especially critical when reviewing the 72 percent increase in homepage traffic to the homepage search widget compared with the 55 percent decrease in homepage traffic to the research databases page. it is important to note these trends do not mean the library’s other research databases have fallen in usage by 55 percent. though there was not a comprehensive examination of usage statistics, spot-checking suggested ebsco and non-ebsco subject databases had both increases and decreases in usage from previous years. another issue libraries should consider, especially when preparing for instruction classes, is that users do not seem to understand which information needs are suited to a discovery tool versus the catalog or subject-specific databases. several tasks provided additional information about users’ mental models of the tool, which may help libraries make better decisions about navigation customizations in discovery tool interfaces and on library websites. task 7 was designed to discover whether users could find their way to a database outside of eds if they knew they needed to use a specific database. six participants, including one of the faculty members, began by searching eds for the name of the sculpture and/or the database name. on task 1, a graduate information technology and libraries | march 2012 101 student who searched on “death of a salesman” and was asked to comment on how quick search results compared to his or her previous experience, said, “i would still have liked to see more critical sources on the play but i could probably have found more results of that nature with a better search term, such as ‘death of a salesman criticism.’” while true, most librarians would suggest using a literary criticism database, which would target this information need. librarians may have differing opinions regarding the best research starting point, but their rationale would be much different than that of the students in this study. this study’s participants said they would use quick search/eds when they were doing class work or research, but would not use it for general inquiries. if librarians were to list which user information needs are best met by a discovery tool versus a subject-specific database, the types of information needs listed would be much more numerous and diverse, regardless of differences over how to classify them. in addition to helping users choose between a discovery tool or a subject-specific database, libraries will need to conceptualize how users will move in and out of the discovery tool to other library resources, services, and user accounts. while users had no trouble finding the ask-alibrarian link in the header, it might have been more informative if users started from a searchresults page to see if they would find the right-hand column’s ask-a-librarian link or links to library subject guides and database lists. discovery tools vary in their abilities to connect users with their online library accounts and are changing quickly in this area. this study also provided some interesting observations about discovery tool interfaces. the default setting for ebsco discovery service is a single search box. however, this study suggests that while users desire a single search, they are willing to use multiple interface options. this was supported by log analysis of the library’s locally developed entry widget, quick search, in which 28 percent of searches included the use of a drop-down menu. on the first usability task, users left quick search’s options set to the default. on other tasks, participants frequently used the dropdown menus and limiters in both quick search and eds. for example, on task 2, which asked them to look for videos, five users looked in the quick search format drop-down menu. on the same task within eds, six users attempted to use the source type facet. use of limiters was similarly observed by williams and foster in their eds usability study.38 one eds interface option that was not obvious to participants was the link to change the sort order. when asked to find the most recent article, only two participants changed the sort option. most others used the date input boxes to limit their search, then selected the first result even thought it was not the most recent one. it is unclear whether the participant assumed the first result was the most recent or whether they could not figure out how to display the most recent sources. finding a journal title from library homepages has long been a difficult task,39 and this study provided no exception, even with the addition of a discovery tool. it is important to note that the standard eds implementation would include a “publications” or “journals a–z” link in the header; usability test results for a discovery tool in an academic library | fagan et al 102 in eds, libraries can customize the text of this link. jmu did not have this type of link enabled in our test, since the hope was that users could find journal titles within the eds results. however, neither eds nor the quick search widget’s search interfaces offered a way to limit the search to a journal title at the time of this study. during the usability test, four participants changed the field search drop-down menu to “title” in eds, and three participants changed the eds field search drop-down menu to “so journal title/source,” which limits the search to articles within that journal title. while both of these ideas were good, neither one resulted in a precise results set in eds for this task unless the user also limited to “jmu catalog only,” a nonintuitive option. since the test, jmu has added a “journal titles” option to quick search that launches the user’s search into the journal a–z list (provided by serials solutions). in two months after the change (february and march 2011), only 391 searches were performed with this option. this was less than 1 percent of all searches, indicating that while it may be an important task, it is not a popular one. like many libraries with discovery tools, jmu added federated search capabilities to eds using ebscohost integrated search software in an attempt to draw some traffic to databases not included in eds (or not subscribed to through ebsco by jmu), such as mla international bibliography, scopus, and credo reference. links to these databases appeared in the upper-righthand column of eds during the usability study (see figure 6.) usage data from ebsco showed that less than 1 percent of all jmu’s eds sessions for fall 2010 included any interaction with this area. likewise, williams and foster observed their participants did not use their federated search until explicitly asked to do so.40 perhaps users faced with discovery tool results simply have no motivation to click on additional database results. since the usability test, jmu has replaced the right-hand column with static links to ask-a-librarian, subject guides, and research database lists. readers may wonder why one of the most common tasks, finding a specific book title, was not included in this usability study; this was because jmu libraries posed this task in a concurrent homepage usability study. on that study, twenty of the twenty-five participants used quick search to find the title “pigs in heaven” and choose the correct call number. eleven of the twenty used the quick search drop-down menu to choose a title search option, further confirming users’ willingness to limit up-front. the average time on this task was just under a minute, and all participants completed this task successfully, so this task was not repeated in the eds usability test. other studies have reported trouble with this type of task;41 much could depend on the item chosen as well as the tool’s relevance ranking. user satisfaction with eds can be summarized from the open-ended post–study questions, from the responses to task 1 (figure 5), and the sus scale. answers to the post–study questions indicated participants liked the ability to narrow results, the speed and ease of use, and relevance of the system. a few participants did describe the system as being “overwhelming” or “confusing” because of the many features, which was also supported by the sus scores. jmu has been using the sus to understand the relative usability of library systems. the sus offers a benchmark for system improvement; for example, ebsco discovery service received an sus of only 37 in spring 2010 (n information technology and libraries | march 2012 103 = 7) but a 56 on this study in fall 2010 (n = 10). this suggests the interface has become more usable. in 2009, jmu libraries also used the sus to test the library catalog’s classic interface as well as a vufind interface to the library catalog, which received scores of 68 (n = 15) and 80 (n = 14), respectively. the differences between the catalog scores and eds indicate an important distinction between usability and usefulness, with the latter concept encompassing a system’s content and capabilities. the library catalog is, perhaps, a more straightforward tool than a discovery tool and attempts to provide access to a smaller set of information. it has none of the complexity involved in finding article-level or book chapter information. all else being equal, simpler tools will be more usable. in an experimental study, tsakonas and paptheodorou found that while users did not distinguish between the concepts of usability and usefulness, they prefer attributes composing a useful system in contrast to those supporting usability.42 discovery tools, which support more tasks, must make compromises in usability that simpler systems can avoid. in their study of eds, williams and foster also found overall user satisfaction with eds. their participants made positive comments about the interface as well as the usefulness and relevance of the results.43 jmu passed on several suggestions to ebsco related to eds based on the test results. ebsco subsequently added “audio” and “video” to the source types, which enabled jmu to add a “just videos at jmu” option to quick search. while it is confusing that “audio” and “video” source types currently behave differently than the others in eds, in that they limit to jmu’s catalog as well as to the source type, this behavior produces what most local users expect. a previous usability study of worldcat local showed users have trouble discriminating between source types in results lists, so the source types facet is important.44 another piece of feedback provided to ebsco was that on the task where users needed to choose the most recent result, only two of our participants sorted by date descending. perhaps the textual appearance of the sort option (instead of a drop-down menu) was not obvious to participants (see figure 6); however, williams and foster did not observe this to be an issue in their study.45 future research the findings of this study suggest many avenues for future research. libraries will need to revisit the scope of their catalogs and other systems to keep up with users’ mental models and information needs. catalogs and subject-specific databases still perform some tasks much better than discovery tools, but libraries will need to investigate how to situate the discovery tool and specialized tools within their web presence in a way that will make sense to users. when should a user be directed to the catalog versus a discovery tool? what items should libraries continue to include in their catalogs? what role do institutional repositories play in the suite of library tools, and how does the discovery tool connect to them (or include them?) how do library websites begin to make sense of the current state of library search systems? above all, are users able to find the best resources for their research needs? although research on searchers’ mental models has been extensive,46 librarians’ mental models have not been studied as such. yet placing the usability test results for a discovery tool in an academic library | fagan et al 104 discovery tool among the library’s suite of services will involve compromises between these two models. another area needing research is how to instruct users to work with the large numbers of results returned by discovery tools. in subject-specific databases, librarians often help users measure the success of their strategy—or even their topic—by the number of results returned: in criminal justice abstracts, 5,000 results means a topic is too broad or the search strategy needs refinement. in a discovery tool, a result set this large will likely have some good results on the first couple of pages if sorted by relevance; however, users will still need to know how to grow or reduce their results sets. participants in this study showed a willingness to use limiters and other interface features, but not always the most helpful ones. when asked to narrow a broad subject on task 3 of this study, only one participant chose to use the “subject” facet even when the subtopic, audiology, was clearly available. most added search terms. it will be important for future studies to investigate the best way for users to narrow large results set in a discovery tool. this study also suggested possible areas of investigation for future user studies. one interesting finding related to this study’s users’ information contexts was that when users were asked to search on their last research topic, it did not always match up with their major: a voice performance student searched on “current issues in russia,” and the hospitality major searched on “aphasia.” to what extent does a discovery tool help or hinder students who are searching outside their major area of study? one of jmu’s reference librarians noted that while he would usually teach a student majoring in a subject how to use that subject’s specific indexes, as opposed to a discovery tool, a student outside the major might not need to learn the subject-specific indexes for that subject and could be well served by the discovery tool. future studies could also investigate the usage and usability of discovery tool features in order to continue informing library customizations and advice to vendors. for example, this study did not have a task related to logging into a patron account or requesting items, but that would be good to investigate in a follow-up study. another area ripe for further investigation is discovery tool limiters. this study’s participants frequently attempted to use limiters, but didn’t always choose the correct ones for the task. what are the ideal design choices for making limiters intuitive? this study found almost no use of the embedded federated search add-on: is this true at other institutions? finally, this study and others reveal difficulty in distinguishing source types. development and testing of interface enhancements to support this ability would be helpful to many libraries’ systems. conclusion this usability test of a discovery tool at james madison university did not reveal as many interface-specific findings as it did questions about the role of discovery tools in libraries. users were generally able to navigate through the quick search and eds interfaces and complete tasks successfully. tasks that are challenging in other interfaces, such as locating journal articles and discriminating between source types, continued to be challenging in a discovery tool interface. information technology and libraries | march 2012 105 this usability test suggested that while some interface features were heavily used, such as drop down limits and facets, other features were not used, such as federated search results. as discovery tools continue to grow and evolve, libraries should continue to conduct usability tests, both to find usability issues and to understand user behavior and satisfaction. although discovery tools challenge libraries to think not only about access but also about the best research pathways for users, they provide users with a search that more closely matches their expectations. acknowledgement the authors would like to thank patrick ragland for his editorial assistance in preparing this manuscript. correction april 12, 2018: at the request

“halfway home: user centered design and library websites” in the march 2018 issue of information technology and libraries (ital), i thought there were some interesting points. i think that your assertion, however, that user centered design automatically eliminates anything from a website that your main user group did not expressly ask for is faulty. when someone brings up the fact that user centered design is not statistically significant, i interpret that as a misunderstanding of what user centered design is. our academic library websites are not research projects so why would we gather statistically significant information about them? our academic library websites are (or should be) helpful to students and faculty and constantly changing to meet their needs. if librarians perpetuate a misunderstanding of user centered design, my fear is that misunderstanding could perpetuate stagnation and a refusal to change our technology/user interfaces in a rapidly changing environment and do our patrons and ourselves a disservice. user centered design is a set of tools to help us gather information about users and their needs. the information gathered informs the design but does not dictate the design and needs to be part of an iterative process. the web design team at your institution demonstrated user centered design when they added floor maps back into the web site when a group of users pointed out that it was causing problems for the main users at your institution. while valuable experience from librarians and other staff is critical to take into account, it is sometimes difficult to determine which pieces of the puzzle provide comfort to those who work at the library vs. which pieces assist students in their studies. i applaud your willingness to “clear the slate” and reduce the amount of information you were maintaining on your website. i’m guessing you may have removed dozens of links from your website. you only mentioned adding one category of information back into the design. i would say your user centered design process is working quite well. ann kucera systems librarian central michigan university https://doi.org/10.6017/ital.v37i1.10338 virtual reality: the next big thing for libraries to consider editorial board thoughts virtual reality: the next big thing for libraries to consider breanne kirsch information technology and libraries | december 2019 4 breanne kirsch (breanne.kirsch@briarcliff.edu) is university librarian, briar cliff university. i had the pleasure of attending educause annual conference from october 14-17, 2019. this was my first time at educause, but i was impressed with the variety of programs, vendors, and options for learning about technology and higher education. after recently completing my coursework for a second master’s in educational technology, i was curious to see what new technologies would be highlighted at educause. i found out about some new trends, such as the growth of esports in high schools and higher education. esports are when players or teams compete through computers in video game competitions.1 there were over 20 programs and sessions about virtual reality at educause. since there were so many programs about virtual reality at educause, i wanted to share a little of what i learned including how some higher education institutions are creating vr content, using pre-created content, and vr in libraries. since virtual reality is still new to many higher education institutions, i wasn’t sure how many would be creating content, but i did attend a couple of sessions about how 360 -degree content is being created. virtual reality content creation seems to happen most frequently in the medical field so students can practice different procedures that may not happen very frequently in their jobs, allowing them to experience a wider variety of procedures that they will eventually encounter in the workplace. health sciences libraries are generally ahead of the curve in providing vr services to patrons.2 additionally, stem areas are finding more uses for vr, such as vr laboratories so expensive lab equipment does not need to be purchased, but students can still participate in vr lab experiences. creating vr content using tools such as unity can be difficult and time-consuming. some educators are using 360-degree cameras to create virtual settings that can be used by students but are easier to create. tim fuller and rich kappel spoke about how they used a 360-degree camera and matterport scans to create 360-degree virtual environments for students to explore and engage with robotics technology. tags can then be added to include pictures, videos, or link to websites with more information. this creates a shareable link that can be used to share with students. i was able to use my iphone and the google street view app to create a 360-degree tour of my library. it is not high quality enough to view in virtual reality with an oculus go or other vr headset, but it is a great starting point for creating a 360-degree virtual tour of a library on a budget. this was free (since i already had an iphone). there is a wide variety of freely available, 360-degree content that can be used by educators in the classroom and more is being created. what does this mean for libraries? while quick virtual tours can be created with smartphones, higher quality vr experiences can also be created by librarians using a 360-degree video camera. these experiences could be used to teach students information literacy skills or search strategies in a vr environment. while this would be harder to do right now with the technologies available, mailto:breanne.kirsch@briarcliff.edu virtual reality: the next big thing for libraries to consider | kirsch 5 https://doi.org/10.6017/ital.v38i4.11847 it could become easier down the road. meanwhile, librarians can create 360-degree virtual tours. libraries can offer vr services, such as a vr lab or checking out standalone vr headsets, such as oculus go or oculus quest. just like with the makerspaces trend, libraries are well situated to support virtual reality in education. our library circulates an oculus go and when we were considering adding a virtual reality headset, there were some risks we considered prior to purchasing it. there are health risks for some people when using virtual reality headsets, such as motion sickness, dizziness, and, in some cases, epileptic seizures. it is important to explain this to students before they check out the device, so they know to immediately quit using the oculus go if they have an adverse reaction. additionally, we keep cleaning wipes with the oculus go to help keep it sanitary when multiple people are using it. a tablet or smart phone needs to be associated with the oculus go in order to update apps or download new apps. therefore, a passcode needs to be added so students can’t purchase paid apps on the oculus go with the associated credit card. privacy can also be a concern, especially when using the social apps, which is why i decided not to download the social apps on the oculus go at this time. some of the scary apps, such as the face your fear app can cause students to scream, so it is important that students realize how realistic the experiences are before using them. one final consideration when offering vr services is staffing. there needs to be someone trained in the library that can help teach students how to use the vr headset and experiences. i’ve trained each of our student workers in how to use the headset so they can show other students. while these are some important considerations when deciding whether to offer vr services or not, i believe the benefits outweigh the risks. virtual reality is expected to continue to grow, especially with wireless headsets, such as the oculus go and oculus quest available. it is important for libraries to be ready to offer support with virtual reality, just as we’ve offered support for prior technologies including tablets, laptops, computers, 3d printers, etc. libraries can start small, by circulating an oculus go or creating a 360-degree library tour. libraries with more resources could create a vr lab or provide support for creating vr content, such as 360 -degree video cameras or tools like unity. it will be exciting to see how libraries can support vr in the future. further readings van arnhem, jolanda-pieta, christine elliott, and marie rose. augmented and virtual reality in libraries. lanham: rowman & littlefield, 2018. varnum, kenneth j. beyond

attractive. sadly, these enhancements often overlook users who rely on assistive technology, leaving electronic content difficult for this user base despite the potential of electronic materials to be easier for them to access and read than print materials. even when providers are somewhat aware of this user group's needs there are questions about the effect of their efforts to date and whether accessibility documentation from them can be relied upon. this study examines selected vendors’ vpat reports (voluntary product accessibility template) through a manual assessment of their database platforms to determine their overall accessibility. introduction libraries are now providing more access to online databases than ever before. in fact, as blechner notes, most of the “information patrons seek is located in indexes and databases that are only available digitally. students and faculty rely heavily on these resources in completing course assignments and conducting research.”1 vendors frequently revamp simpler interfaces of their database platforms with script-enriched interfaces to make it more attractive to students.2 sadly, these enhancements often overlook users who rely on assistive technology, leaving electronic content difficult for this user base despite the potential of electronic materials to be easier for them to access and read than print materials. online databases not only bridge the gap for distance users but can also improve service to users with print disabilities.3 resources produced digitally or properly digitized for online dissemination more readily allow all users, including patrons with physical or mental impairments, to make use of them than do print materials. these resources allow all patrons to have access to updates and new publications at the same time, and can be presented in multiple formats.4 key features of electronic access that are helpful to users are zooming in on text and automatic reflow to reduce the need to scroll, improving color contrast or changing colors to make looking at the screen easier on the eyes, and the capability of the text to be read aloud by either a built-in feature or user-provided assistive technology such as a screen reader or refreshable braille display.5 all of this, however, presupposes that the content can be accessed using the platform provided by the vendor to navigate the database, and that the documents be made at least minimally accessible. the question is then, how well do these platforms interact with the assistive technologies employed by the largest minority group in the united states (persons with disabilities), relying on libraries to facilitate “their full participation in society,” and to achieve academic success?6 many vendors provide accessibility documentation pertaining to their database platforms. some note considerable limitations in accessibility while others claim to be highly accessible when in mailto:samuel.willis@wichita.edu mailto:faye.oreilly@wichita.edu information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 2 fact they may be no better that the former. accessibility guidelines like section 508 of the rehabilitation act sets forth are a good starting point, but related literature has emphasized that even conformance to these standards does not guarantee they will be usable for all.7 literature review accessibility in libraries has been examined from a variety of vantage points. some studies were an inspiration to our work and complementary to it, though our manual and holistic review of library databases from third parties was a unique approach. dermody and majekodunmi conducted a usability study of electronic databases, focusing on students unable to fully make use of analog materials.8 they asserted that technology, online databases in particular, can either be a help or a hindrance to users with print disabilities.9 after having visually impaired students use screen readers to test three proprietary databases, the authors concluded that their use of the platforms was disrupted by advanced features designed to engage users. study participants were frustrated to have to abandon a research article applicable to their topic because it was presented in an unreadable format.10 the authors found that as website design evolves to enhance the user experience, screen reader users and others who relied on assistive technology were often overlooked and unable to make use of the sites due to the construction of the platforms and due to inaccessible pdfs.11 regarding accessibility assessment, the authors asserted that database providers were unlikely to catch all issues or evaluate their products accurately.12 the legal responsibility for these shortfalls, however, belongs to the subscribing institutions.13 the results of dermondy and majekodunmi’s survey demonstrated that the usability of electronic databases was stunted by the limitations of screen readers, the platforms or materials themselves, and by insufficient information literacy training for assistive technology users. in 2015, blechner wrote about the challenges law students with disabilities face in their education, similar to any undergraduate or graduate program. this study was conducted by a librarian with screen-reading software and an accessibility checklist. blechner highlighted that using research databases with assistive technology to locate material and complete assignments was a barrier to completing legal education programs or passing the bar.14 in academic institutions, student success is related to library access. as much of a library’s resources are online, inaccessible electronic resources present a massive issue.15 database design is especially important to users who use assistive technologies to access online resources. blechner pointed out that an additional barrier to online resource access was an average delay of three years before an accessible version of a requested platform or service was prepared.16 if an undergraduate degree took four years to complete, a freshman living with a disability would be a senior before they have equitable access. blechner stressed a need for librarians to go beyond addressing the accessibility of their native web platforms and to inspect vendor platforms prior to subscribing to them. libraries "rarely raise the issue when selecting electronic indexes and databases for procurement from outside vendors.”17 libraries cannot adequately serve patrons and comply with legal requirements if they are unable to provide meaningful access to information for all library patrons. a significant point from blechner’s article was that compliance with federal standards does not guarantee a service is easy to use or usable at all. “a product can receive a rubber stamp even when it is not functional or usable despite a company’s good faith efforts to provide an accessible product.”18 other authors have supported this claim, which, along with our own observations, was an impetus for this research. information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 3 in chapter 8 of ensuring digital accessibility through process and policy, lazar, goldstein, and taylor used different web accessibility evaluation methods to verify vendor accessibility information on their platforms. the three methods they examined were (1) having users with disabilities test the platform or content using assistive technology; (2) conducting an expert review to ensure compliance with usability standards; and (3) performing an automated scan of the content using scanning software. regardless of method chosen for evaluation, the authors stressed the importance of continuous evaluation, as content can easily become inaccessible through changes to the user interface. the authors identified strengths and weaknesses to each of the approaches but recommended that whenever possible method one be used from early on in the development with a goal of ongoing improvement, and that method two be used in conjunction with it. when specifically examining the accessibility review of vendor-supplied database content, the authors noted that a voluntary product accessibility template (vpat) is one form of method two; however, its findings are only reliable insofar as the template is completed by an accessibility expert, and even then there is room for disagreement. 19 this supported the approach we undertook in this study to examine vendor databases and compare our findings with vendors’ vpats when available. in our professional experience, some vpat creators are experts in accessibility, while others are not, and even among experts opinions vary, which led us to the same conclusion as lazar et al.: “multiple experts, working independently, can increase the validity of the accessibility inspection.”20 jennifer tatomir created a checklist, the tatomir accessibility check-list (tac), to apply the accessibility guidelines to a usability study.21 at the time the article was written in 2010, the thencurrent web accessibility standards would have been the wcag 2.0 (released in 2008) and section 508 standards, last revised in 1998 to include equitable access to information and data under the protection of the law. wcag is now in version 2.1, with version 2.2 already in development, and section 508 requirements were updated in 2017 to include many wcag principles. the tac examined (1) documents and webpages; (2) bypass links; (3) page element labels; (4) captions for images and figures; (5) scripts and code that would interfere with assistive technology; (6) duplicate links; (7) transcripts for audiovisual material; (8) site organization; (9) timed responses; and (10) the accessibility of web forms.22 while the testing criteria used in this study differed from ours on several points, tatomir and durrance’s work supported our creation of the accessibility remediation guide (arg), a checklist of which section 508 standards would be the most important to our libraries (see appendix a). the arg will be discussed in more detail later in this article. finally, delancey conducted an assessment of the accuracy of 17 vendors’ vpats which was similar to one aspect of our research. her work used automated assessment tools as the primary measure for comparison against vpats, while this study is a direct comparison of two expert reviews.23 the goal of our research project was to determine the accuracy of vendor-supplied accessibility documentation—vpats in particular—to inform future communications with those vendors as well as collection development decisions moving forward. the studies used in this paper used sighted librarians, students using screen readers , and native users of screen readers to conduct accessibility testing. ideal candidates for accessibility testing would of course be users with disabilities. however, this approach can be complemented by a review for basic usability and compliance with section 508 standards. librarians are also ideal candidates for accessibility testing since they have access to and expertise in using research databases and are committed to providing access to all.24 librarians can also provide information information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 4 in advance, in anticipation of need. the findings of such accessibility testing could be beneficial in drafting licensing agreements that would ensure a higher level of service for patrons with disabilities. as blechner said, it is “critical that libraries independently exercise their power as buying agents to improve the state of electronic resource accessibility.”25 librarians can be instrumental in the development of database platforms moving forward by continually checking the accessibility of these platforms and sharing opportunities for enhancement with vendors.26 methodology this study made use of the arg (appendix a) for both vpat accuracy analysis, and overall testing of database accessibility. the arg was based on the standards set forth in section 508 of the rehabilitation act and related vpat creation guidelines. the arg has 11 criteria and was originally intended for accessibility evaluation of new databases, but two criteria were merged with others to make nine in order for it to be easier for a graduate student to evaluate. due to the breadth of technologies covered in a vpat, the authors determined that many of the sections in a vpat were not relevant to our examination. an example of this is section 1194.25 which refers to physical accessibility of kiosks and the like and therefore has no bearing on electronic content. the functionalities we chose to test were a restricted subset of the functionalities assessed in a vpat, but this set was selected for several reasons. some of the guidelines were selected due to their wide impact on a variety of assistive technologies related to the needs of persons with disabilities including blindness, deafness, limited vision, hearing, or mobility. following these guidelines would improve the performance of the platforms for use with screen readers and keyboards, eye tracking software, refreshable braille displays, and other assistive technology.27 other tests were chosen as a result of our preliminary investigation and use of the databases, and resulting evidence that they were areas on concern. finally, some of these items to be examined were selected because a lack of accessibility in these areas would result in drastic limitations to the usability and therefore utility of the databases overall, even if they rarely applied. the reasons behind this study were threefold. firstly, 62 percent (48) of our vendors had provided no vpat. this test would fulfill a similar purpose, allowing us to know how accessible these databases without vpats were as well as identify particular areas requiring remediation in anticipation of patron needs. secondly, our library had anecdotal evidence that some of the vpats that were provided contained inaccuracies but without a thorough examination it was impossible to know the particulars or extent of the issues. finally, the goal of the project was to identify trends in database accessibility and usability for persons with disabilities, comparing major database providers with smaller vendors. these findings will give insight into what most needs to be addressed based on the size and type of content provider and will likely have some bearing on similar institutions’ collections. these are the criteria we used in testing. other institutions, if following our example, would likely want to adapt the list to meet their needs and institutional priorities: 1) keyboard navigation and intuitive forms 2) presence of keyboard traps 3) platform optical character recognition (ocr) 4) document ocr 5) alternative text 6) table data information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 5 7) skip navigation 8) transcripts 9) closed captions note: criteria 3, 8, and 9 included testing support materials, including video tutorials for criteria 8 and 9. once we had determined which sections to include, we hired and trained a graduate student to use the arg to examine each database to which we subscribed on the nine criteria. we were awarded a grant to fund the student’s work. the student tested each database platform and a minimum of three items in each database, manually checking them using a keyboard and screen reader (nvda). this testing fulfilled the majority of our priorities but was supplemented by her checking for transcripts and captions for video content. while the findings cannot be comprehensive in a manual test this work is complementary with existing vpats in enabling us to identify areas in need of development in vendor platform usability. it is noteworthy that by testing the databases manually with a screen reader, certain limitations in the usability of the databases were discovered that would not have been revealed by doing automatic checks as have been done in similar studies. an excellent example of this is poorly designed skip navigation (which was found for nearly half of our databases). using the data we collected with the assistance of our graduate student, we compiled and compared our findings on the various vendors. our scoring (based on representative random sampling) gave one point for a database passing a single criterion, half a point for a minor issue, and no points for any criteria that failed our tests. the scores were then added together, ignoring any criteria which did not apply to particular databases, to form a composite score. when analyzing vendors with multiple databases, their overall score was based on the average of the individual database scores. this enabled us to codify a percentage of accessibility for every vendor and compare them. for the purposes of this study, we will refer to any vendor that provided the university libraries with 15 or more database subscriptions as large vendors (lvs), and the rest as small vendors (svs). given that we only subscribe to 15 or more databases from a few vendors, some of the vendors we classified as svs would likely be considered lvs at other institutions. research findings vpat accuracy assessment as previously stated, one goal of this research was to measure the accuracy of vendor-supplied vpats. 227 databases assessed had an associated vpat from the vendor, but the rest did not ( see appendix b for list of all databases by vendor). we used the arg (appendix a), and compared the vendors’ claims on the vpat to our manual testing of the database functionality. of the 227 databases, only 10 databases were found to fully match the claims the vendor made on the vpat for the 11 criteria assessed from the arg. databases where the vpat claims did not match the findings of the testing on one criteria were given a score of “partial match.” of the 227 databases, 138 were considered partial matches (see figure 1 for details). the main incongruity between vpats and our results were due to the databases not having sufficient skip navigation, meaning they did not have appropriate or functional bypasses. these issues are likely due to outdated vpats that do not reflect the latest changes to the databases but could also be the result of vendors’ lack of understanding of what it means to be truly usable by persons with disabilities. information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 6 for databases that failed two or more of the criteria tested, a score of “not a match” was given, with 79 databases of 227 failing (see figure 1 for details). for these databases, skip navigation and alternative text were the main issues. the databases, when presenting essential content in an image, like a photo or chart, did not provide an alternative presentation of that content, which means only sighted users could access the data from that image. the findings of this study are similar to the data from the overall usability study, finding that vendors struggled with skip navigation and alt-text, as we will discuss below. some of these databases were also found to have keyboard traps that prevented screen reader users from navigating to the entire site and at times may even trap the user’s navigation in a single content area. this number of inconsistencies was even higher than the authors anticipated but reinforced all the more the importance of not taking information in vpats for granted, especially when the vpat is several years old and the platform has undergone any changes. figure 1. vpat accuracy assessment accessibility analysis overall related to the vpat accuracy assessment, we conducted manual tests of our databases and database platforms, both those with and without a vpat provided by the vendor. of our 351 databases, 124 (35 percent) had no related vpat, and on a whole, examining all criteria, we found them notably less accessible. that said, there were exceptions where databases with no associated vpat still had accessibility information giving reasonable detail, and others where the vpat provided was inaccurate or where it highlighted significant accessibility issues (see tables 1 and 61% 4% 35% partial match match not a match information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 7 2). the average composite score of vpat-linked databases was 74 percent, compared to 67 percent for those with none (see table 3 for comparison). each criterion was compared and any instance where one category of databases was more than five percent higher than the other was highlighted. table 1. summary of issues for databases with vpats (227 total) good partial poor applicable n/a download ocr 50

average 73.57% 67.04% the biggest barriers to accessibility found in this study pertained to downloadable files’ ocr, skip navigation, transcripts, and alternative text (see figure 2 and table 4). the accessibility of downloadable files through ocr or alternative formats (txt, html, etc.) was found to be the most major concern, though it did not apply to all databases. its overall score for applicable databases was 51 percent, based on the frequency and severity of the issues. many database platforms had full text available for download only through pdfs that were images of text or that had other issues failing to work with assistive technologies. it was more than twice as frequent for a database to have inaccessible downloadable files as inaccessible full text online. often html or txt formats were not available for download, but in instances where it was available through the vendor’s platform, another means of accessing the information mitigated this issue. other times, however, the full text on the platform itself was not accessible. information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 9 figure 2.

greatest number of issues by vendor. this criterion’s final score was 55 percent. when skip navigation existed, the most common problem was for it to not redirect to the main content. often times, for example, on the search results page, the link would take the user to the filters in the margin with no easy way to bypass them and get to the actual results. eighty-three databases were found to have no skip navigation whatsoever, but the majority of issues found were from existing bypass links not working as intended. d o w n l o a d o c r s k i p n a v i g a t i o n t r a n s c r i p t s a l t t

technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 10 databases with audiovisual materials made up a relatively small portion of our databases, but when these types of items existed, problems were not infrequent. additionally, we examined support videos made available by database providers to test all multimedia content for transcripts and captions. twenty-seven out of 72 (38 percent) were determined to have inaccurate transcripts or be in need of them. captions are irrelevant to non-visual materials, so were only applicable to 54 databases. of these, 13 (24 percent) were found lacking. therefore, transcripts were the bigger issue. nearly half of the databases with images had at least minor issues with alternative text, whether in documents or the platforms themselves. in many cases, this issue was not identified by the vendor in any accessibility documentation because alternative text was present, but not properly descriptive. thirty-eight databases (16 percent of applicable) had major issues where images were important to the performance of the platform or database and no alternative text was provided. in database materials, charts and graphs were often lacking any alternative text, though on occasion we found the information conveyed in the chart was covered in the main text. in these instances, that was not counted as an issue. the results for tables were similar. both in the platforms and the documents, tables often lacked identifying header and cell information for screen readers to make sense out of the data. a few were entirely unreadable. fifty-two of 99 databases with tabular data (53 percent) had problems, but most of them were not major, and for this reason, tables were of less concern than alternative text. finally, keyboard navigation was a rarer issue, but still was found to be a concern in 75 databases (21 percent). this was often related to images or forms not having descriptive text for screen readers, so non-visual users would be unable to know the purpose of the form, etc. on a few occasions database platforms would have keyboard traps that prevented screen reader users from navigating to the entire site, or more often at least buttons or links that could be used only with a mouse. while our testing only included keyboard navigation, it is important to remember that if it is not usable by keyboard, neither is it likely to work with other assistive technology used for navigation. while this area was of least frequent concern of all criteria we tested, it is nevertheless a vital part of making any website or platform truly usable. all these findings were important to our study as they helped us to identify areas of need, especially for databases that had no corresponding vpat. whether the databases had a vpat or not, this research provided us with the details needed to reach out to database providers and request specific improvements. vendor comparison by size the final goal of our research was to compare the relative accessibility of database providers based on the number of databases we subscribed to from each. while at times we may have subscribed to only a small number of databases from a larger content provider, there was a general correlation between what we considered svs in this study and those vendors that only offer a more limited number of collections. in assessing the percent accessible a provider was for each criterion, we added all good scores, one point for each related database, to the partial scores, one half a point for each, then divided it by the total number of databases in this area. in this way, minor issues were not recorded as negatively as major issues. overall accessibility of the lv databases was found to be significantly higher than accessibility of individual databases and svs (see tables 5 and 6 for findings for lvs and svs respectively). our information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 11 findings showed our lvs to have an average score of 74 percent accessibility, compared to 69 percent for svs, both averages being based on the number of applicable databases. there were two tested criteria, however, that lvs scored lower on than svs: downloadable files’ ocr, and tables. the details of each criterion will be discussed below. most lv content is on a consistent platform and we found, similar to an earlier study, that this consistency helped those materials to be more accessible.28 the issues lv databases most often had were related to individual items, rather than to the platform as a whole. for example, lvs were found to have frequent problems with pdf files. given that our lvs account for 61 percent of our databases (214 of 351) and they are typically larger than the databases of svs, this has significant impact on ongoing vendor communication and accessibility remediation efforts. skip navigation issues was the largest problem found for svs. interestingly, while no lvs were entirely missing skip navigation, a lack of proper functionality was a major concern for half of them, accounting for 121 databases. thirteen databases were found where lvs had no skip navigation. in contrast, 70 sv databases (52 percent of sv content for which this criterion applied) had no skip navigation or it failed to function at all. an additional 30 sv databases and 121 lv databases had improperly functioning bypass links. overall, svs were more likely to have none at all, and lvs were more likely to have it not properly set up. full text ocr results varied greatly depending on the type. platform ocr showed little difference between lvs and svs, both being found to be 82 percent accessible. as mentioned previously, downloadable files ocr had more accessibility problems than platform ocr, but there was a large difference between lvs and svs. for this criterion lv content was found to be only accessible about 40 percent of the time, and sv content 70 percent of the time. this may be due to svs generally having smaller databases so it is less difficult to address accessibility needs for individual items. whatever the cause, the disparity between lvs and svs in this area was very significant. transcripts and captions were far more common for lvs than svs. fifty-five databases (26 percent of lv databases) included audiovisual material, including support tutorials, while only 17 (12 percent) of sv content did. lv content was found to be accessible 73 percent of the time for transcripts, and 82 percent for captions. applicable svs on the other hand were only 41 percent accessible for transcripts, and 66 percent accessible for captions. this demonstrates the need for development in both these areas, but especially for transcripts, which when synchronized with the videos have the capability to full more user needs than captions can. closely following transcripts was alternative text for non-textual content like charts, diagrams and other images. it is worth mentioning that some databases have images neither in their platforms nor in their collection materials. if the platform is simple and the database only provides abstracts, for example, there may be no images, in which case this criterion does not apply. nearly one-third (113) of the databases were found to have no images. of the 238 databases with images, we found at least some issues with 115 (48 percent of applicable, 33 percent overall), there being no significant difference between svs and lvs as a whole. individually, the platforms varied greatly, and regarding major limitations in alternative text there were found to be 21 sv databases, but only 17 lv databases. information technology and libraries december 2020 filling the gap in database usability | willis and o’reilly 12 while table accessibility applied to only 99 databases, there were significant issues found particularly with one lv. given the disparity between lvs it is impossible to draw meaningful conclusions comparing lvs and svs for this criterion. further study is needed in this area. finally, the areas of least frequent concern were keyboard navigation and keyboard traps. seventy-five databases (21 percent) were found to have suboptimal navigation. in this case, lvs did not have as many issues as svs. optimization is needed for them, but only one lv had major issues in this area. forty percent of sv databases (55 of 137) had at least some navigation issues identified, whereas only nine percent of lv databases (20 of 214) had any issues in this area. as for major issues, only four databases were identified in our study as having keyboard traps, two svs and two lvs. these only seemed to appear for separate platforms and never for large ones, suggesting that our vendors are likely aware of this issue and avoiding it in newly created platforms. the authors hope the remaining databases with this issue will not be neglected in making these improvements. to sum up, lv content was found to be more accessible overall. their largely consistent platforms more often had skip navigation (29 percent more), transcripts (32 percent more) and captions (16 percent more) for multimedia content, and superior keyboard navigation (18 percent more). sv platforms, however, had a higher score on downloadable files ocr (31 percent more) and on tables (24 percent more). see table 7 for detailed comparison. table 5. issues by lv database (214 total) good

intended to complement existing studies related to library database accessibility. it was unique in that it manually analyzed content from every database subscription in the university libraries, rather than only major or representative databases or automated tests. building a comparison between vendor vpats and our manual assessment was a key value of this research that we hope will be further developed in future inquiry. the comparison of different types of vendors was also important. while the consistency of lv platforms was found to improve the sites overall, the authors expected that lv content would be more compliant with accessibility regulations than they were found to be. from a usability and accessibility perspective, the increased cost of these databases was deemed to be associated with too little improvement of service. it matters little how clean a platform looks to visual users, for example, if it is impossible or very difficult to use by non-visual users. as anticipated, there were few instances of keyboard traps (when a keyboard and screen reader user is caught in a loop or on a single link when attempting to navigate through the website). when these occur, however, it is a major concern, as it renders the site virtually useless for non-mouse users. there was no significant difference between lvs and svs on three of nine criteria—including keyboard traps— and on two criteria, svs were superior. therefore, despite that lvs were found to be 14 percent more accessible on average, the authors urge lvs to work diligently to address the areas where they were found to be deficient. both aspects of this study concluded that vendors generally misunderstood the execution of sk ip navigation and alternative text, as a usability study of databases proved many databases failed in fulfilling these criteria, while a separate study of their vpats’ accuracy proved vendors claimed they did comply with the criteria, while the platform was found to not comply fully. this study is limited in that few samples were able to be examined for each content type in every database platform. the authors anticipate that a deeper investigation would bring to light additional accessibility concerns. another limitation of this research was related to the time involved in testing. database platforms changed during the course of this work, but the results of this study pertain to only a short period of time, making them in cases outdated even at the time of this writing. therefore, the manual testing we have performed would work best when used in conjunction with automated tools for testing database content as other studies have done. the authors hope that further study in this area could involve persons with varied impairments to test the platforms directly and assert that there is potential for collaboration between vendors and libraries in this area. information technology and libraries december 2020 filling the gap in database

bibliographic records (frbr)’s hierarchical system defines families of bibliographic relationship between records and collocates them better than most extant bibliographic systems. certain library materials (especially audio-visual formats) pose notable challenges to search and retrieval; the first benefits of a frbrized system would be felt in music libraries, but research already has proven its advantages for fine arts, theology, and literature—the bulk of the non-science, technology, and mathematics collections. this report will summarize the benefits of frbr to nextgeneration library catalogs and opacs, and will review the handful of ils and catalog systems currently operating with its theoretical structure. editor’s note: this article is the winner of the lita/ ex libris writing award, 2007. t he following review addresses the challenges and benefits of a next-generation online public access catalog (opac) according to the functional requirements for bibliographic records (frbr).1 after a brief recapitulation of the challenges posed by certain library materials—specifically, but not limited to, audiovisual materials—this report will present frbr’s benefits as a means of organizing the database and public search results from an opac.2 frbr’s hierarchical system of records defines families of bibliographic relationship between records and collocates them better than most extant bibliographic systems; it thus affords both library users and staff a more streamlined navigation between related items in different materials formats and among editions and adaptations of a work. in the eight years since the frbr report’s publication, a handful of working systems have been developed. the first benefits of such a system to an average academic library system would be felt in a branch music library, but research already has proven its advantages for fine arts, theology, and literature—the bulk of the non-science, technology, and mathematics collections. ■ current search and retrieval challenges the difficulties faced first, but not exclusively, by music users of most integrated library systems fall into two related categories: issues of materials formats, and issues of cataloging, indexing, and marc record structure. music libraries must collect, catalog, and support materials in more formats than anyone else; this makes their experience of the most common ils modules—circulation, reserves, and acquisitions—by definition more complicated. the study of music continues to rely on the interrelated use of three distinct information formats—scores (the notated manifestation of a composer’s or improviser’s thought), recordings (realizations in sound, and sometimes video, of such compositions and improvisations), and books and journals (intellectual thought regarding such compositions and improvisations)—music libraries continue to require . . . collections that integrate [emphasis mine] these three information formats appropriately.3 put a different way, “relatedness is a pervasive characteristic of music materials.”4 this is why frbr’s model of bibliographic relationships offers benefits that will first impact the music collection.5 at present, however, musical formats pose search and retrieval challenges for most ils users, and the problem is certainly replicated with microforms and video recordings. the marc codes distinguish between material formats, but they support only one category for sound recordings, lumping together cd, dvd audio, cassette tape, reel-toreel tape, and all other types.6 this single “sound recording” definition is easily reflected in opacs (such as those powered by innovative interfaces’ millennium and ex libris’ aleph 500) and union catalogs (such as worldcat. org).7 however, the distinction between sound recording formats is embedded in subfields of the 007 field, which presently cannot be indexed by many library automation systems because the subfields are not adjacent. an even more central challenge derives from the fact that music sound recordings—such as journals and essay collections—contain within each item more than one work. thus, for one of the central material formats collected by a music library (as well as by a public library or other academic branches), users routinely find themselves searching for a distinct subset of the item record. perversely, though music catalogers do tend to include analytic added-entries for the subparts of a cd recording or printed score, and major ils vendors are learning to index them, aacr2 guidelines set arbitrary cutoff points of about fifteen tracks on a sound recording, and three performable units within a score.8 subsets of essay collections and journal runs are routinely exposed to users’ searches by indexing and abstracting services and major databases, but subsets of libraries’ music collections depend upon catalogers to exploit the marc records for user access.9 timothy j. dickey (dickeyt@oclc.org) is a post-doctoral researcher, oclc office of programs and research, dublin, ohio. frbrization of a library catalog: better collocation of records, leading to enhanced search, retrieval, and display timothy j. dickey 24 information technology and libraries | march 200824 information technology and libraries | march 2008 in light of these pervasive bibliographic relationships, catalogers of music (again, with parallels in other subjects) have developed a distinctive approach to the marc metadata schema. in particular, they—with their colleagues in literature, fine arts, and theology—rely upon the 700t field for uniform work titles, and upon careful authority control.10 however, once again, many major ils portals have spotty records in affording access to library collections via these data. innovative interfaces’ millennium, though it clearly leads other major library products in this market, frequently frustrates music librarians (it is, of course, not alone in doing so).11 its automatic authority control feature works poorly with (necessary) music authority records.12 and even though innovative has been one of the first vendors to add a database index to the 700t field, partly in response to concerns expressed to the company by the music librarians’ user group, millennium apparently does not allow for an appropriate level of follow-through on searching.13 an initial search by name of a major composer, for instance, yields a huge and cluttered result set containing all indexed 700t fields.14 the results do helpfully include the appropriate see also references, but those references disappear in a subsidiary (limited) search. in addition, the subsidiary display inexplicably changes to an unhelpful arrangement of generic 245 fields (“mozart, symphonies”; “mozart, operas, excerpts”). similar challenges will be faced by other parts of an academic or large public library collection, including the literature collections (for works such as shakespeare’s plays), fine arts (for images and artists’ works), and theology (for works whose uniform title is in latin). the opac interfaces of other major ils vendors fare little better. the same search (for “mozart”) on the emory university library catalog (with an ils by sirsidynix), similarly yields a rich results set of more than one thousand records, and poses similar problems in refining the search.15 in the case of this opac, an index of 700t fields also exists, but it only may be searched from the inside of a single record; as with millennium, sirsidynix’s interface will then group the next set of results confusingly by 245 fields. the library corporation’s carl-x apparently does not contain a 700t index; the simple “mozart” search returns a muchsimplified set of only 97 results organized by 245a fields, and thus offers a more concise set of results but avoids the most incisive index for audio-visual materials.16 ex libris offers a somewhat more helpful display of its more restricted results; unfortunately for the present comparison, though the detailed results set does list the “format” of all mozart-authored items, the same term— “music”—is used for sound recordings, musical scores, and score excerpts, with no attempt logically to group the results around individual works.17 no 700t index appears present. ■ the frbr paradigm: review of literature and theory from the earliest library catalogs in the modern age, the tools of bibliographic organization have sought to afford users both access to the collection and collocation of related materials. anglo-american cataloging practice has traditionally served the first function by main entries and alternate access points and the second function by classification systems. however, as knowledge increases in scope and complexity, the systems of bibliographic control have needed to evolve. as early as the 1950s, theories were developing that sought to distinguish between the intellectual content of a work, and its often manifold physical embodiments.18 the 1961 paris international conference on cataloging principles first reified within the cataloging community a work-item distinction, though even the 1988 publication of the anglo-american cataloging rules, 2nd ed., “continued to demonstrate confusion about the nature . . . of works.”19 meanwhile, extensive research into the nature of bibliographic relationships groped toward a consensus definition of the entity-types that could encompass such relationships.20 ed o’neill and diane vizine-goetz examined some one hundred editions of smollett’s the expedition of humphrey clinker over a two-hundred-year span of publication history to propose a hierarchical set of definitions to define entity levels.21 the theoretical entities include the intellectual content of a work—which in the case of audio-visual works, may not even exist in any printed formats—the various versions, editions, and printings in which that intellectual content manifests itself, and the specific copies of each manifestation which a library may hold.22 research has discovered such clusters of bibliographically related entities for as much as 50 percent or more of all the intellectual works in any given library catalog, and as many as 85 percent of the works in a music catalog.23 this work laid the foundation for frbr (and, once again, incidentally underscored the breadth of its applicability to, and beyond, music catalogs). the theoretical framework of frbr is most concisely set forth in the final report of the ifla study group. the long-awaited publication traces its genesis to the 1990 stockholm seminar, and the resultant 1992 founding of the ilfa study group on functional requirements for bibliographic records. the study group set out to develop: a framework that identifies and clearly defines the entities of interest to users of bibliographic records, the attributes of each entity, and the types of relationships that operate between entities . . . a conceptual model that would serve as the basis for relating specific attributes and relationships . . . to the various tasks that users perform when consulting bibliographic records. article title | author 25frbrization of a library catalog | dickey 25 the study makes no a priori assumptions about the bibliographic record itself, either in terms of content or structure.24 in other words, the intention of the group’s deliberations and the final report is to present a model for understanding bibliographic entities and the relationships between them to support information organization tools. it specifically adopts an approach that defines classes of entities based upon how users, rather than catalogers, approach bibliographic records—or, by natural extension, any system of metadata. the frbr hierarchical entities comprise a fourfold set of definitions: ■ work: “a distinct intellectual or artistic creation”; ■ expression: “the intellectual or artistic realization of a work” in any combination of forms (including editions, arrangements, adaptations, translations, performances, etc.); ■ manifestation: “the physical embodiment of an expression of a work”; and ■ item: “a single exemplar of a manifestation.”25 examples of these hierarchical levels abound in the bibliographic universe, but frequently music offers the quickest examples: ■ work: mozart’s die zauberflöte (the magic flute) ■ work: puccini’s la bohéme ■ expression: the composer’s complete musical score (1896) ■ manifestation: edition of the score printed by ricordi in 1897 ■ expression: an english language edition for piano and voices ■ expression: a performance by mirella freni, luciano pavarotti, and the berlin philharmonic orchestra (october 1972) ■ manifestation: a recording of this perfor mance released on 33¹/³ rpm sound discs in 1972 by london records ■ manifestation: a re-release of the same per formance on compact disc in 1987 by london records ■ item: the copy of the compact disc held by the columbus metropolitan library ■ item: the copy of the compact disc held by the university of cincinnati in fact, lis research has tended to demonstrate what music librarians have always understood—that relatedness among items and complexity of families is most prevalent in audio-visual collections. even before the ifla report had been penned, sherry vellucci had set out the task: “to create new catalog structures that better serve the needs of the music user community, it is important first to understand the exact nature and complexity of the materials to be described in the catalog.”26 even limiting herself to musical scores alone (that is, no recordings or monographs), vellucci found that more than 94.8 percent of her sample exhibited at least one bibliographic relationship with another entity in the collection; she further related this finding to the very “inherent nature of music, which requires performance for its aural realization,” as opposed to, for example, monographic book printing.27 vellucci and others have frequently commented on how the relatedness of manifestations—in different formats, arrangements, and abridgements—of musical works continues to be a problem for information retrieval in the world of music bibliography.28 musical works have been variously and industriously described by musicologists and music bibliographers. yet, in the information retrieval domain [and, i might add, under both aacr and aacr2] . . . systems for bibliographic information retrieval . . . have been designed with the document as the key entity, and works have been dismissed as too abstract . . .29 the work is the access point many users will bring—in their minds, and thus in their queries—to a system. they intend, however, to discover, identify, and obtain specific manifestations of that work. very recently, research has begun to demonstrate that the frbr model can offer specific advantages to music retrieval in cases such as these: “the description of bibliographic data in a frbr-based database leads to less redundancy and a clearer presentation of the relationships which are implicit in the traditional databases found in libraries today.”30 explorations of the theory in view of the benefits to other disciplines, such as audio-visual and other graphic materials, maps, oral literature, and rare books, have appeared in the literature as well.31 the admitted weakness of the frbr theory, of course, is that it remains a theory at its inception, with still preciously few working applications. ■ frbr applications working implementations of frbr to catalogs, opacs, and ilss are still relatively few but promise much for the future. the frbr theoretical framework has remained an area of intense research at oclc, which has even led to some prototype applications and, very recently, deployment in the worldcat local interface.32 a scattered few other researchers have crafted frbr catalogs and catalog displays for their own ends; the library of congress has a prototype as well. innovative, the leading academic ils vendor, announced a frbr feature for 2005 release, 26 information technology and libraries | march 200826 information technology and libraries | march 2008 yet shelved the project for lack of a beta-testing partner library.33 ex libris’ primo discovery tool, one other complete ils (by visionary technologies for library systems, or vtls), and the national library of australia, have each deployed operational frbr applications.34 the number of projects testifies to the high level of interest among the cataloging and information science communities, while the relatively small number of successful applications testifies to the difficulties faced. oclc has engaged in a number of research projects and prototypes in order to explore ways that frbrization of bibliographic records could enhance information access. oclc research frequently notes the potential streamlining of library cataloging by frbrization; in addition they have experienced “superior presentation” and “more intuitive clustering” of search results when the model is incorporated into systems.35 work-level definitions stand behind such oclc research prototypes as audience level, dewey browser, fictionfinder, xisbn, and live search. in every case, researchers determined that, though it was very difficult to automate any identification of expressions, application of work-level categories both simplifies and improves search result sets.36 an algorithm common to several of these applications is freely available as an open source application, and now as a public interface option in oclc’s worldcat local.37 the algorithm creates an author/title key to cluster worksets (often at a higher level than the frbr work, as in the case of the two distinct works that are the book and screenplay for gone with the wind). in the public search interface, the results sets may be grouped at the work level; users may then execute a more granular search for “all editions,” an option that then displays the group of expressions linked to the work record. unfortunately, as the software does not use 700t fields (its intention is to travel up the entity hierarchy, and it uses the 1xx, 24x, and 130 fields), its usefulness in solving the above challenges may not be immediate. a somewhat similar application (though merrilee proffitt declares it not to be a frbr product) was redlightgreen, a user interface for the exrlg union catalog based upon quasi-frbr clustering.38 the reports from designers of other automated systems offer interesting commentaries on the process. the team building an automatically frbrized database and user interface for austlit—a new union collection of australian literature among eight academic libraries and the national library of australia—acknowledged some difficulty with non-monographic works such as poems, though the majority of their database consisted of simpler work-manifestation pairs.39 based on strongly positive user feedback (“the presentation of information about related works [is] both useful and comprehensible”), a similar application was attempted on the australian national music gateway musicaustralia; it is unclear whether the project was shelved due to difficulties in automating the frbrization process.40 one recent application created for the perseus digital library adopts a somewhat different approach.41 rather than altering previously created marc records to allow hierarchical relationships to surface, this team created new records using crosswalks between marc and, for instance, mods, for work-level records. they claim some moderate level of success; though once again, their discussion of the process is more illuminating than their product. mimno and crane successfully allowed a single manifestation-level record to link upwards to many expressions, a necessary analytic feature especially for dealing with sound recordings. they did practically demonstrate the difficulty of searching elements from different levels of the hierarchy at the same time (such as work title and translator), a complication predicted by yee.42 three ils vendors have released products that use the frbr model: portia (visualcat), ex libris (primo), and vtls (virtua).43 the first product, a cataloging utility from a smaller player in the vendor market, claims to incorporate frbr into its metadata capture, yet the information available does not explain how, nor do they offer an opac to exploit it. the 2007 release of ex libris’ primo offers what the company calls “frbr groupings” of results.44 this discovery tool is not itself an ils, but promises to interoperate with major existing ils products to consolidate search results. it remains unclear at this time how ex libris’ “standard frbr algorithms” actually group records; the single deployment in the danish royal library allows searching for more records with the same title, for instance, but does not distinguish between translations of the same work.45 vtls, on the other hand, has since 2004 offered a complete product that has the potential to modify existing marc records—via local linking tags in the 001 and 004 fields—to create frbr relationships.46 their own studies agreed with oclc that a subset, roughly 18 percent, of existing catalog records (most heavily concentrated in music collections) would benefit from the process, and they thus allow for “mixed” catalogs, with only subsets (or even individually selected records) to be frbrized. the company’s own information suggests relatively simple implementation by library catalogers, coupled with robust functionality for users, and may be the leading edge of the next generation of catalog products. ■ frbr solutions the ilfa study group, following its user-centered approach, set out a list of specific tasks that users of a computer-aided catalog should be able to accomplish: article title | author 27frbrization of a library catalog | dickey 27 ■ to find all manifestations embodying certain criteria, or to find a specific manifestation given identifying information about it; ■ to identify a work, and to identify expressions and manifestations of that work; ■ to select among works, among expressions, and among manifestations; and ■ to obtain a particular manifestation once selected. it seems clear that the frbr model offers a framework of relationships that can aid each task. unfortunately, none of the currently available commercial solutions may be in themselves completely applicable for a single library. the oclc work-set algorithm is open source, as well as easily available through worldcat local, but it only works to create super-work records; it also ignores the 700t field so crucial to many of the issues noted above. none of the other home-grown applications may have code available to an institution. the virtua module from vtls offers a very tempting solution, but may require a change of vendor.47 either adapting one of these solutions or designing a local application, then, raises the question: what would the ideal system entail? catalog frbrization will transpire in two segments: enhancing the existing catalog to add bibliographic relationships to surface in the retrieval phase, and designing or adaptating a new interface and display to reflect the relationships.48 the first task may prove the more formidable, due to the size of even a modest catalog database and the difficulties often observed in automating such a task; while the librarians constructing the austlit system found a relatively high percentage of records could be transferred en masse, the oclc research team had difficulty automatically pinpointing expressions from current marc records.49 despite current technology trends toward users’ application of tags, reviews, and other metadata, a task as specialized as adding bibliographic relationships to the catalog demands specialized cataloging professionals.50 the best approach within a current library structure may be to create a single new position to head the project and to act as liaison with cataloging staff in the various branches and with vendor staff, if applicable. each library branch may judge on its own the proportions of records to frbrize, beginning with high-traffic works and authors, those for whom search results tend to be the most overwhelming and confusing to users. each branch can be responsible for allocation of cataloging staff effort to the process, and will thus have specialist oversight of subsets of the database. three technical solutions to actually changing the database structure have been attempted in the literature to date: incrementally improving the existing marc records to better reflect bibliographic relationships, adding local linking tags, and simply creating new metadata schemas. the vtls solution of adding local linking tags seems most appropriate; relationships between records are created and maintained via unique identifiers and linking statements in the 001 and 004 fields.51 oclc’s open source software could expedite the creation of work-level records, and the creation of expression-level records will be made easier by the large amount of bibliographic information already present in the current catalog. wherever possible, cataloging staff also should take the opportunity to verify or create links to authority files so as to enhance retrieval.52 creating a new catalog display option could be accomplished via additions to current opac coding, either by adopting worldcat local or by designing parts of a new local interface. it need not even require a complete revision; the single site (ucl) currently deploying vtls’ frbrized interface maintains a mixed catalog and offers, once again, a highly intuitive model.53 when a searcher comes across a bibliographic record for which frbr linking is available, they may click a link to open a new display screen. we should strive, however, to use simple interface statements such as “view all different kinds of holdings,” “this work has x editions, in y languages” or “this version of the work has been published z times” (both the oclc prototype and the austlit gateway offer such helpful and user-friendly statements). though the foundational work of both tillett and smiraglia focused upon taxonomies of relationships, the hierarchical structure of the ifla proposal should remain at the forefront of the display, with a secondary organization by type of relationship or type of entity. rather than adopting a design which automatically refreshes at each click, a tree organization of the display should be more user-friendly, allowing users to maintain a visual sense of the organization that they are encountering (see appendix for screenshots of this type of tree display).54 format information should be included in the display, as an indication of a users’ primary category, as well as a distinction among expressions of a work. with these changes, the library catalog will begin to afford its users better access to many of its core collections. frbrization of even part of the catalog—concentrating on high-incidence authors, as identified by subject specialists—will allow it better to reflect, and collocate, items within the families of bibliographic relationships that have been acknowledged a part of library collections for decades. this increased collocation will begin to counteract the pitfalls of mere keyword searching on the part of users, especially in conjunction with renewed authority work. finally, frbr offers a display option in a revamped opac that is at the same time simpler than current result lists, and more elegant in its reflection of relatedness among items. each feature should better 28 information technology and libraries | march 200828 information

hambrick, nancy lensenmayer, and joan lippincott, for their helpful comments on earlier drafts. the curricular assignment asked for a library automation proposal in a specific library setting; the original review contained a set of recommendations concerning frbr through the lens of a (fictional) medium-sized academic library system, that of st. hildegard of bingen catholic university. as will be noted below, the branch music library typically serves a small population of music majors (graduate and undergraduate) within such an institution, but also a large portion of the student body that use the library’s collection to support their music coursework and arts distribution requirements. any music library’s proportion of the overall system’s holdings may be relatively small, but will include materials in a diverse set of formats: monographs, serials, musical scores, sound recordings in several formats (cassette tapes, lps, cds, and streaming audio files), and a growing collection of video recordings, likewise in several formats (vhs, laser discs, and dvd). it thus offers an early test case for difficulties with an automated library system. 3. dan zager, “collection development

ippoliti (cinthya.ippoliti@ucdenver.edu) is university librarian and director, auraria library, university of colorado. critical librarianship has brought many changes in how libraries have examined their programs and services, created new positions dedicated to equity, inclusion, and diversity, and paved the way to challenge existing assumptions about our work and environment. technology also exists in a space that is not neutral, as library systems and services reflect specific perspectives in their content and focus as well as how they are made accessible (or not). i would like to briefly examine how we can begin to think about these issues within academic libraries, and offer some additional readings for further reflection for four technology-related areas: spaces, services/programming, systems, and engaging with our users. technology spaces we might assume that because we are seeing students using our classrooms, makerspaces, and study areas, that we have been successful in meeting the needs of a wide variety of users. to a large extent that may be true, but we should also be asking ourselves who does not feel welcome in such a space and, more importantly, why not? there are two facets to this question. the first involves the degree to which libraries strive to create a welcoming environment. staff interactions, signage, hours, and institutional values are all part of a complex and broader environment that signals to users how these spaces function and how they are perceived by the organization. these same elements can also serve as deterrents through choices in layout, policy, or other intangible aspects so that they may in fact prevent individuals from entering these spaces in the first place. the second revolves around the notion that each technology-rich space conveys its level of friendliness and intended purpose through its physical presence. ensuring that furniture, paint, and layout are compliant with ada standards, and integrating these features with each other as opposed to setting them apart so that they are not considered “special” or “different,” is one small and vital step in this direction. maggie beers and teggin summers cover these issues an educause review article and discuss asking questions regarding how power structures are reinforced by having a “front” of the room or other configurations can enrich planning and assessment efforts. similarly, developing a plan so that new technology in areas such as makerspaces rotates as much as possible will help to provide access for those who may not be able to utilize these resources outside of the library context in order to accommodate differing skill levels, interests, and learning styles. in addition, students may not always be present on campus due to family, job, or other life circumstances and planning with the assumption that everyone who could benefit from using a particular space is in fact taking advantage of that benefit, is problematic. one way around that is to ensure that each space is as flexible as possible and (ideally) can be reconfigured for quiet reflection, collaborative work, or transformed into a sensory space or other type of specialized environment. the reservation process should be available both online and manually (as not critical technology | ippoliti 6 https://doi.org/10.6017/ital.v37i4.10810 everyone may have access to a computer and/or the internet), hour limitations should have several counter options, and the space should be available as much of the time as possible when it is not in use for more a more formalized purpose. any space usage assessments should also purposefully include non-users or perceived non-users and integrate questions about barriers to or about the space in their methodologies. finally, ensuring that the right level of staffing to support both the intended, as well as perhaps the unintended, uses of the space and the activities that occur within it will help create a sense that not only the space itself is valued, but that the experiences occurring within it are even more important. this is not easy to accomplish, as it is difficult to predict exactly how a space will be used unless there are very strict confines placed around its configuration and accessibility. but assuming that most spaces in libraries are designed to be malleable and keeping in constant communication with users via some of the methods described above should help. technology services and programming similarly, services and programs cannot be built around a one-size-fits-all model. this can prove to be quite challenging given the limited resources libraries face. engagement and learning lie not only in access to tools, but in the very process of sharing knowledge and experiences — whether for academic growth, social action, or simply personal enjoyment. matt ratto, who coined the term “critical making,” defines it as the process “intended to highlight the interwoven material and conceptual work that making involves.” he argues that “critical making is dependent on open design technologies and processes that allow the distribution and sharing of technical work and its results.” ratto makes the further point that this process also has the capacity of “unpacking the social and technical dimensions of information technologies.” this in turn allows for technology to become more than simply a cool resource, but rather a mechanism for democratizing this creative work of making and designing while dealing with its messy, political, and uncomfortable aspects which do not exist in vacuum outside of the tools themselves. an approach in this instance might involve taking technology outside of library spaces such as on campus or within the community, offering as much for free as possible, and capitalizing on programs such as girls who code (https://girlswhocode.com/) and grow with google (https://grow.google/). capturing how these resources are used in all of their possible permutations enables stories of individuals to shine through. the impact of these programs takes on a personal element through showcases, speaker events, and hackathons that are designed to bring the community together and engage in sharing of knowledge, perspectives, and conversations. in addition, this will hopefully shrink the barriers for those who don’t see themselves as having a role in these activities. integrated library systems i do not have a background in systems, but simon barron and andrew preater have written a great chapter unpacking the inherent power structures which manifest themselves in library systems such as the integrated library system (ils), discovery interfaces, and the third-party resources we provide access to. they suggest taking action by thinking about user privacy and ensuring that the information libraries are able to view, gather, and store is used ethically and that decisions for derivative services or actions are not made based on assumptions about gender identity, economic status, or other identifiers via access to these types of data. openness is another area the authors explore, as they discuss how libraries can use open source software whenever possible in order to balance the field against profit-based licensing models. barron and preater also raise a concern however that while crowdsourcing is in theory a good way to include the community in https://girlswhocode.com/ https://grow.google/ information technology and libraries | december 2018 7 developing ways to help itself, it still does not recognize the limited resources marginalized populations can dedicate to these efforts. finally, they discuss how it is crucial for libraries to recognize and support the expertise needed in this arena in order to avoid overreliance on vendor systems that can prove alluring with out-of-the-box solutions, but which compromise things like privacy, autonomy, and customization that might otherwise benefit from equity, diversity, and inclusion-centered practices. equity-driven design engaging with users in developing shared solutions to challenges is an important aspect of the user experience, and can help pave the way for deeper conversations. taking a step back and making sure the assessment and design process itself is transparent for everyone is one of the first things that needs to be in place. i would like to harken to the work of gretchen rossman and sharon rallis who make a crucial distinction between user-centered design, in which the user seldom has a voice in what the final process or product looks like, and what they term as “emancipatory design,” in which participants are “collaboratively producing knowledge to improve their work and their lives.” in addition, emancipatory design is one where “users are in charge; their power, their indigenous knowledge are more powerful and respected than those of the expert designer.” this approach can therefore be a means to promoting equity, diversity, and inclusion into technology work in libraries by focusing on the users’ voice as opposed to our own and working collaboratively to develop shared solutions to address their challenges. a specific example of how this framework might be applied comes from the stanford school of design which is famous for its course in design thinking. stanford has recently taken that concep t even further, and integrated an equity focus into the first steps of the progression, where the designer is not only identifying existing built-in biases but also raises questions such as who the users are, what are the equity challenges that need to be addressed, who has institutional power, and how is it manifested in the decisions that drive the organization. the stanford model also provides specific methods focusing on human values and developing relational trust as a way to bookend the design thinking process by reflecting on the blind spots that were uncovered as a way to help inform action items and next steps and ensure that the users are actively collaborating to develop these services and programs which in turn affect them. this version of the program is available at https://dschool.stanford.edu/resources/equity-centered-design-framework. as a final thought, one idea to keep at the forefront in all of these areas is that of universal design, which is defined by the center for universal design at ncsu as “the design of products and environments to be useable by all people, to the greatest extent possible, without the need for adaptation or specialized design.” the first principle is that of equitable use and can be applied to many technology-related aspects whether they are physical or virtual: • provide the same means of use for all users: identical whenever possible; equivalent when not • avoid segregating or stigmatizing any users • provisions for privacy, security, and safety should be equally available to all users • make the design appealing to all users https://dschool.stanford.edu/resources/equity-centered-design-framework critical technology | ippoliti 8 https://doi.org/10.6017/ital.v37i4.10810

information technology and libraries | december 2012 1 past and present converge with the december 2012 issue of information technology and libraries (ital), as we also publish online the first volume of ital’s predecessor, the journal of library automation (jola), originally published in print in 1968. the first volume of jola offers a fascinating glimpse into early days of library automation, when many things were different, such as the size (big) and capacity (small) of computer hardware, and many things were the same (e.g., richard johnson’s description of the book catalog project at stanford, where “the major achievement of the preliminary systems design was to establish a meaningful dialogue between the librarian and systems and computer personnel.” plus ça change, plus c'est la meme. there are articles by luminaries in the field: richard de gennaro describes approaches to developing an automation program in a large research library, frederick kilgour, from the ohio bob

open-access publication. while we don’t have readership statistics for the previous print journal to compare with, download statistics for the e-version appear healthy, with more than 30,000 full-text article downloads for 2012 content so far this year, plus more than 10,000 downloads for content from previous years. based on the download statistics, the topics of most interest to today’s ital readers are discovery systems, web-based research guides, digital preservation, and digital copyright. this month’s issue takes some of these themes further, with articles that examine the usability of autocompletion features in library search interfaces (ward, hahn, and feist), reveal patterns of student use of library computers (thompson), propose a cloud-based digital library storage solution (sosa-sosa), and summarize attributes of open standard file formats (park, oh). happy reading. 20190318 10979 gallley editorial board thoughts who will use this and why? user stories and use cases kevin m. ford information technology and libraries | march 2019 5 kevin m. ford (kefo@loc.gov) is librarian, linked data specialist, library of congress. perhaps i’m that guy. the one always asking for either a “user story” or a “use case,” and sometimes both. they are tools employed in software or system engineering to capture how, and importantly why, actors (often human users, but not necessarily) interact with a system. both have protagonists, but one is more a creative narrative, the other like a strict, unvarnished retelling. user stories relate what an actor wants to do and why. use cases detail to varying degrees how that actor might go about realizing his desire. the concepts, though distinct, are often confused and conflated. and, because they classify as jargon, the concepts have sometimes been employed outside of technology to capture what an actor needs, the path the actor takes to his or her objective, including any decisions that might be made along the way, and all of this effort is undertaken in order to identify the best solution. by giving the actors a starring role, user stories and use cases ensure focus is on the actors, their inputs, and the expected outcome. they protect against incorporating unnecessary elements, which could clutter and, even worse, weaken the end product, and they create a baseline understanding by which the result can be measured. and so i find myself frequently asking in meetings, and mumbling in hallways: “what’s the use case for that?” or “is there a user story? if not, then why are we doing it?” you get the idea. it’s a little ironic that i would become this person. not because i didn’t believe in user stories and use cases – quite the contrary, i’ve always believed in the importance and utility of them – but because of a book i was assigned during graduate coursework for my lis degree and my initial reaction. it’s not just an unassuming book, it has a downright boring appearance, as one might expect of a book entitled “use case modeling.”1 it’s a shocking 347 pages. it was a joint endeavor by two authors: kurt bittner and ian spence. i think i read it, but i can’t honestly recall. i assume i did because i was that type of student and i had a long chicago el commute at the time. in any case, i know beyond doubt that i was assigned this book, dutifully obtained it, and then picked it up, thumbed through it, rolled my eyes, and probably said, “ugh, really?” and that’s just it. the joke’s on me. the concepts, and as such the book, which i’ve moved across the country a couple of times, remain near-daily constants in my life. as a developer, i basically don’t do anything without a user story and a use case, especially one whose steps (including preconditions, alternatives, variables, triggers, and final outcome) haven’t been reasonably sketched out. “sketched out” is an interesting phrase because one would think that if entire books were being authored on the topic of use cases, for example, then use cases would be complicated and involved affairs. they can be, but they need not be. the same holds for user stories. imagine you were designing a cataloging system, here’s an example of the latter: as a librarian i want my student catalogers to be guided through selection of vocabulary terms to improve both their accuracy and speed.2 editorial board thoughts: who will use this and why? | ford 6 https://doi.org/10.6017/ital.v38i1.10979 that single-sentence user story identifies the actors (student catalogers), what they need (a “guided … selection of vocabulary terms”), and why (“to improve their accuracy and speed”). the use case would explore how the student catalogers (the actors) would interact with the system to realize that user story. the use case might be narrowly defined (“adding controlled terms to records”) or might be part of a broader use case (“cataloging records”), but in either instance the use case might go to some length to describe the interaction between the student catalogers and the system in order to generate a clear understanding of the various interactions. by doing this, the use case helps to identify functional requirements and it clearly articulates user/system expectations, which can be reviewed by stakeholders before work begins and used to verify delivery of the final product. as i have presented this, using these tools might strike you as overly formal and time-consuming. in many circumstances they might be, if the developer has sufficient user and domain knowledge (rare, very, very rare) and especially if the “solution” is not an entirely new system but just an enhancement or augmentation to an existing system. yet, whether it is a completely new system being developed by someone who has long and profound experience with the domain or a simple enhancement, it may be worth entertaining the questions/process if even informally. i find it is often sufficient to ask “who will use this and why?” essentially i’m asking for the “user story” but dispensing with the jargon. doing so may lead to additional questions, the answers to which would likely check the boxes of a “use case” even if the effort is not identified as such, and it certainly ensures the user-driven nature and need of the request. this might all sound obvious, but i like to think of it as defensive programming, which is like defensive driving. yes, the driver coming up to the stop sign on my right is going to stop, but i take my foot off the gas and position it over the brake just in case. likewise, i’m confident the functional requirements i’m being handed have been fully considered and address a user need, but i’m going to ask for the user story anyway. i’m also leery of scope creep which, if i were to continue the driving analogy, would be equivalent to driving to one store because you need to, but then also driving to two additional stores for items you think might be good to have but for which you have no present need. it’s time-consuming, you’ve complicated your project, you’ve added expense to your budget, and the extra items might be of little or no use in the end. the number of times i’ve been in meetings in which new, additional features are discussed because the designers think it is a good idea (that is, there has been no actual user request or input sought) is alarmingly high. that’s when i pipe up, “is there a user story? if not, then why are we doing it?” user stories and use cases help focus any development project on those who stand to benefit, i.e. the project’s stakeholders, and can guard simultaneously against insufficient planning and software bloat. and the concepts, though most often thought of with respect to large-scale projects, apply in all circumstances, from the smallest feature request to an existing system to the redesign of a complex system. if you are not in the habit of asking, try it next time: who will use this and why? endnotes 1 kurt bittner and ian

proquest pg. 66 china academic library and information system: an academic library consortium in china longji dai, ling chen, and hongyang zhang since its inception in 1998, china academic library and information system (calis) has become the most important academic library consortium in china. calis is centrally funded and organized in a tiered structure. it currently consists of thirteen management or information centers and seventy member libraries' 700,000 students. after more than a year of development in information infrastructure, a calis resource-sharing network is gradually taking shape. l ike their counterparts in other countries, academic libraries in china are facing such thorny problems as shrinking budgets, growing patron demands, and rising costs for purchasing books and subscribing to periodicals. it has thus become increasingly difficult for a single library to serve its patrons to their satisfaction. under these circumstances, the idea of resource sharing among academic libraries was born. library consortia provide an organizational form for libraries to share their resources. the georgia library learning online (galileo), the virtual library of virginia (viva), and ohiolink are among the wellknown library consortia in the united states.i traditionally, the primary purpose of establishing a library consortium is to share physical resources such as books and periodicals among members. more recently, however, advances in computer, information, and telecommunication technologies have dramatically revolutionized the way in which information is acquired, stored, accessed, and transferred. sharing electronic resources has rapidly become another important goal for library consortia. i what is calis? in may 1998, as one of the two public service systems in "project 211," the china academic library and information system (ca lis) project was approved by the state development and planning commission of china after a two-year feasibility study by experts from academic libraries across the country. calis is a nationwide academic library consortium. funded primarily by the chinese government, it is longji dai is director, peking university library, and deputy director, calis administrative center; ling chen is deputy director, calis administrative center; and hongyang zhang is deputy director, reference department, peking university library. 66 information technology and libraries i june 2000 intended to serve multiple resource-sharing functions among the participating libraries-including online searching, interlibrary loan, document delivery, and coordinated purchasing and cataloguing-by digitizing resources and developing an information service network. i structure and management of calis a library consortium is an alliance formed by member libraries on a voluntary basis to facilitate resource sharing in pursuit of common interests. whether a consortium can operate successfully depends in large part on how it is managed. calis differs from library consortia in the united states in that it is a national network. it resembles multistate consortia in the united states with respect to geographic distribution of member libraries, but it is like tightly knit or even centrally funded statewide ones in terms of management.2 the calis members are distributed in twenty-seven provinces, cities, and autonomous regions in china, making an entirely centralized management difficult. after surveying some of the major library consortia in the united states, europe, and russia, calis adopted an organizational mode characterized by a combination of both centralized and localized management-that is, a three-tiered structure (figure 1). in order to improve the management efficiency and maximize the sharing of various resources including funds, calis has established a coordination and management network comprising one national administrative center (which also serves as the north regional center), five national information centers (see table 1) and seven regional information centers (see table 2). the thirteen centers are maintained by full-time staff members provided by the libraries in which these centers are located. the national administrative center (located in peking university)-overseen by officials from the concerned office at the ministry of education and the presidents of peking and tsinghua universities and advised by an advisory committee consisting of experts from major member libraries-is responsible for the construction and management of calis, makes policies and regulations, and prepares resource-sharing agreements. the center has an office handling routine management needs and several specialized work groups overseeing calis' national projects, such as those for the development of databases for union catalogues, current chinese periodicals, and calis' service software. under the guidance of the national administrative center, five national information centers are each responsible for building and maintaining an information system reproduced with permission of the copyright owner. further reproduction prohibited without permission. in one of five general areas-humanities, social science, and science; engineering and technology; agriculture and forestry; medicine; and national defense-in coordination with regional centers and member libraries. the host libraries where these centers are located possess relatively abundant collections in their respective areas. these centers, which are intended to be information bases that cover all major disciplines of science, are responsible for importing databases for sharing and constructing resource-sharing networks among member libraries and for providing searching and document delivery services to member libraries. 5 national information centers 8 regional information centers 70 member libraries depending on their location, academic libraries in china are divided into eight groups, with each forming a regional library consortium. each regional consortium is overseen by a regional management center, except for the consortium in the north, which is directly managed by the national management center. the regional centers not only participate in nationwide projects in coordination with the national centers and other figure 1. the three-tiered structure of calis regional centers, but they also are responsible for promoting cooperation among libraries in their particular regions. all the centers are located in member universities and staffed by the host universities. the concerned vice president or library director of a host university is in charge of the associated center. the regional centers also are assisted by regional coordination committees and advisory committees of provincial and municipal officials in charge of education; university presidents; library directors; and senior librarians in the concerned table 2. table 1. five national information

funding for calis at the present time are as follows: • government grants. much of the funds for the calis project during the first phase of construction came from the government. because of the demonstrated benefits of the ongoing project, it is expected that the government will provide funds for the second phase of calis construction. these government funds have been used in the purchase of software and hardware for the calis centers and commercial databases, development of service software and databases, training of staff members, etc. • local matching funds. according to prior agreements, a province or city that desires to have a regional center is required to provide funds in supplementation to the government funds for the construction of its local center. • member library funds. these funds, primarily derived from the university budgets, have been used to purchase electronic resources and cover the expenses incurred from the use of the calis service software platforms. although calis is currently funded by the government, the future expansion and operation of the system is expected to rely in large part on other sources of fun_ds. the funding needs for calis may be met by operating the system in a commercial mode. i principles for cooperation among members the successful operation of a library consortium clearly depends on good working relationships among members and between members and the consortium. at calis, all members are required to adhere to a set of principles (see below) in dealing with these relationships. it is based on these principles, known as the calis princ~ples for cooperation among members, that calis pohc1es and rules are made. • the common interests of calis are above those of individual member libraries. 68 information technology and libraries i june 2000 • • • • member libraries should not cooperate at the expense of the interests of others. calis provides services to member libraries for no profit. member libraries are all equal and enjoy the same privileges. larger member libraries are obliged to make more contributions. i what has been achieved? when it was first established, calis had sixty-one member libraries from major universities participating in "project 211." later, as many other major universities were interested in joining the alliance, the number of calis members has climbed to seventy. at the present, calis serves about 700,000 students. construction of calis is a long-term, strategic undertaking. the system provides service functions as they become available and is constantly being improved in the process. in the first phase (1998 to 2000) of the project, calis successfully started the following information-sharing functions in its member libraries: • primary and secondary data searching; • interlibrary borrowing and lending; • document delivery; • coordinated purchasing; and • online cataloguing. the following tasks have been completed: • purchase of computer hardware (e.g., sun e~s00); • construction of a cern etor internet-based information-sharing network connecting academic libraries across the country; and • group purchase of databases, such as umi, ebsco, ei village, inspec, elsevier, and web of science, that are shared among member libraries either directly online or indirectly through requested service/ document delivery. calis also has completed development of a number of databases, including: • • union catalogues. these databases currently contain 500,000 bibliographic records of the chinese and western language books and periodicals in all member libraries. dissertation abstracts and conference proceedings . these databases now contain abstracts of doctoral dissertations (12,000 bibliographic records) and proceedings

may access an ill server through web/ill, tracking the status of submitted interlibrary loan requests, inquiring about fees, and so on. the databases that are centrally located and those that are distributed at various locations as well as service platforms in member libraries form a calis information service network. i future considerations in a period of just over a year, considerable progress has been made in forming a nationwide resource-sharing library consortium in china. however, because member libraries vary in size, available funds, staff quality, and automation level, calis has yet to realize its potential. there are a number of problems that remain to be solved. for example, the calis union catalogue databases do not work well on some of the old automation systems in member libraries and the calis service platforms are incompatible with a dozen automation systems currently in use; as a result, the union catalogues cannot tell the real-time circulation status in all member libraries, affecting interlibrary loan service. in addition, primary 70 information technology and libraries i june 2000 resources are not sufficiently abundant. therefore, the extent to which resources are shared among member libraries remains quite limited. in the next phase of development, calis will improve service systems (including hardware and software platforms) and the distribution of shared databases. at the same time, calis will develop more electronic resource databases and be actively involved in the research and development of digital libraries, expanding the scale and extent of resource sharing. references 1. barbara a. winters, "access and ownership in the 21st century: development of virtual collection in consortia! settings," in electronic resources

99 yaqi shen (yqshen@sjtu.edu.cn) is a librarian at shanghai jiao tong university. abstract in this paper, a library-space information model (lsim) based on a geographical information system (gis) was built to visually show the bookshelf location of each book through the display interface of various terminals. taking shanghai jiao tong university library as an example, both spatial information and attribute information were integrated into the model. in the spatial information, the reading room layout, bookshelves, reference desks, and so on were constructed with different attributes. the bookshelf layer was the key attribute of the bookshelves, and each book was linked to one bookshelf layer. through the field of bookshelf layer, the book in the query system can be connected with the bookshelf-layer information of the lsim. with the help of this model, readers can search books visually in the query system and find the books’ positions accurately. it can also be used in the inquiry of special-collection resources. additionally, librarians can use this model to analyze books’ circulation status, and books with similar subjects that are frequently circulated can be recommended to readers. the library’s permanent assets (chairs, tables, etc.) could be managed visually in the model. this paper used gis as a tool to solve the problem of accurate positioning, simultaneously providing better services for readers and realizing visual management of books for librarians. introduction geographical information systems (gis) are powerful tools that can edit, store, analyze, display, and manage geographical data. early in 1992, several association of research libraries (arl) institutions, including the university of georgia, harvard university, north carolina state university, and southern illinois university, launched the gis literacy project and carried out an extensive survey about the possible applications of gis in libraries.1 since then, studies about the application of gis in library research have attracted more and more attention.2 gis is effective for library-planning efforts, such as investigating library-service areas, modeling the implications of the opening and closing of library services, informing initial location decisions, and so on.3 the university of idaho library adopted gis to link variables such as age, race, income, and education from the 2000 us census with the service-area maps of two proposed branch libraries. based on the thematic maps created, the demographic information about potential library users can be displayed. most importantly, the maps were also helpful for improving the library-service planning. koontz et al. from florida state university investigated the reasons for public-library closure by using gis. the authors presented a methodology using gis to describe libraries’ geographic market to illustrate the effects of facility location, relocation, and permanent closure on potential users. sin used gis with inequality measures and multiple regressions to analyze statistics from the public-libraries survey and the census-tract data. then the nationwide library space information model based on gis | shen 100 https://doi.org/10.6017/ital.v37i3.10308 multivariate study of the neighborhood-level variations was investigated, and the public libraries’ funding and service landscapes were mapped. gis can also provide strong support for the library accessibility.4 in south wales, united kingdom, a case study about a preliminary analysis of spatial variations in accessibility of library services was carried out based on a gis model. park further measured the public-library accessibility accurately and provided realistic analysis by using gis, including descriptive and statistical analyses and a road network–based distance measure. in another paper, park went a step further to measure readers’ travel time and distance while they are using the library. in addition to using gis for library planning and accessibility, it can be also applied to managing the collections, including the physical documents and digital databases of an academic library.5 solar and radovan from the national and university library of slovenia explored the possibility of creating a virtual collection of diverse materials like maps and pictorial documents using gis. they connected spatial data with other pictorial elements, including views and portrait images with hyperlinks.6 coyle from rochester public library studied the implementation of gis in the library collection. he believed that libraries that implemented gis early on would have an intellectual advantage over those coming on board later.7 sedighi conducted research about gis as a decisionsupport system in analyzing geospatial data in the databases of an academic library. by using the analysis functions of the system, a range of features could be indicated; for example, the spatial relationships of data based on the educational course can be analyzed.8 boda used a 3d virtuallibrary model to represent the most prominent and celebrated collection of classical antiquity in the alexandria library.9 beyond the applications mentioned above, some libraries have used gis techniques to analyze reader behaviors.10 xia developed gis into an analytical tool for examining the relationships between the height of the shelf and the frequency of book use, revealing that readers tended to pull books off shelves that are easily reachable by human eyes and hands. mandel used gis to map the most popular routes that readers took when entering the library. based on the seating sweeps method, mandel adopted maps to depict use of tables and computers. the research results of both xia and mandel can provide the information of readers’ behavior whereby the books’ positions, and accordingly the entry routes and facilities’ evaluation can be adjusted strategically. though lots of work has been done about the application of gis to the library, there are few reports about visually showing the exact position of each book through the library-catalog display interface, which is of great importance both for the readers and the librarians. xia located library items with gis and pointed out that updating the starting and ending call numbers for each shelf could be the most tedious work.11 specifically, gis cannot tell if the book is not in its correct location or is being used by somebody else. xia advised combining gis with radio frequency identification (rfid), both of which have the capability of tracing the location of each book. stackmap, a library-mapping tool providing a collection-mapping product for librarians, was being used at the hampton library.12 the shanghai jiao tong university library built an interface that would use gis to identify the specific location of each book in the catalog. a gis model that includes spatial and attribute information was constructed. the connection of gis, rfid, and opac was discussed in detail. additionally, the relationship between the bookshelves and patrons’ behavior was studied deeply. information technology and libraries | septmber 2018 101 it is hoped that this gis model will bring convenient services for readers and efficient management for librarians. methodology background in 1984, shanghai jiao tong university circulation system was built based on barcode-reader technology. the first automated library-management system (lms), minisis and image library integrated system, was implemented in 1988. in 1993, the second lms, the unify online multiuser system, was implemented. in 1994, an open public access catalogue (opac) system was built based on the unils, allowing readers to query the library bibliographic record through the computer. in 1998, the third automated lms, a client/server–based tool, was built based on the horizon lms. in 2008, we launched the aleph integrated library system (ils). in the same year, primo, a resource discovery and access system, was introduced. in 2009, the our explore interface was built based on the primo system, providing the services of resource retrieval and access.13 rfid technology was introduced in 2014, and now readers can borrow or return books through self-service machines. users can find a book via the opac or our explore system in the shanghai jiao tong university library homepage (http://www.lib.sjtu.edu.cn/index.php?m=content&c=index&lang=en), a screen shot of which is shown in figure 1. book information can be found through the systems, but the exact position of the books cannot be exhibited in the system. at the library reference desk, the question readers ask most frequently is where they can find a certain book. the chinese library classification (clc) system is used to organize the collections in the shanghai jiao tong university. the librarians are very familiar with the classification. however, it is hard for the inexperienced users to understand, even if they have been trained. although static maps can guide patrons to find the books, patrons sometimes still have difficulties finding the books. if the readers can get the exact bookshelf location for a book through the opac or our explore system, the users’ experience could be improved significantly, and much of readers’ time for finding the books could be saved. therefore, it is necessary to introduce gis to the library with the aim of visually showing the position of each book. furthermore, library managers need to plan the budget at the end of every year. the arrangement of different subjects should be considered in the planning. although the usage of the collections by the ils provides reference for the planning, a library-space information model (lsim) would bring a new insight. software there are many kinds of gis software in this research field, including commercial products such as arcgis, mapinfo, and mapgis as well as free and open-source software (foss) solutions. taking foss and arcgis for example, foss can provide a broader context of the open-source software movement and developments in gis.14 no single foss package can match all the functionality that arcgis has for creating thematic maps; therefore, the function of spatial analysis and data processing of arcgis is more powerful. the software used in this study is arcgis 10.3 trial version.

shanghai jiao tong university library homepage. methods there are two modules in the lsim, including spatial information and attributes information, as shown in figure 2. spatial information, including the building position, the reading-room layout, bookshelf information, and so on, is transferred to shapefile style. remote-sensing information is used to set the geographic location of the library. these elements are constructed with different attributes, and 2d-attribute and 3d-multipatch data are stored in the geodatabase. arcmap and arcscene are used to generate the 2d and 3d maps and analyze the readers’ behavior. we connect the spatial information with data from the opac, our explore, and rfid. the query fields (which we call “general information”) in the opac are title, author, keyword, call number, issn, isbn, system number, barcode, collection location, and publisher. in the our explore system, readers can not only search the general information, but also refine the search results by specific fields, such as topic, author, collection location, published date, and clc. the functions of book reserving and renewing are also supported by these two systems. rfid is introduced to the shanghai jiao tong library to allow self-service, and the fields include collection location, subject, issn, isbn, barcode, and so on. barcode is the common field in all three systems and is used to connect them. in the rfid system, the bookshelf is the unique identification of each shelf in the bookshelves. in the shanghai jiao tong university library, the first-book location method is used to manage books in the rfid system. the first book on each bookshelf is recorded as a different bookshelf location, and the books on one bookshelf are assigned to the same bookshelf location. the books are ordered and arranged according to the call number. a book’s current status can be obtained in the information technology and libraries | septmber 2018 103 rfid system by shelf inventory. the books that are borrowed by patrons or not on the right shelf would be recorded in the rfid system. the key attribute information in the lsim is the bookshelf layer, which is used to describe the book’s position. the field of the bookshelf layer is connected with the rfid data. taking the bookshelf layer of rfid as the attribute field, the position of a book can be located by the bookshelf layer in the lsim. compared to xia’s research, it is easier to get the bookshelf-layer information based on the rfid in the lsim.17 figure 2. research flowchart. the connection of the opac, rfid, and lsim is shown in figure 3. when the reader locates a book in the opac or our explore, the barcode will be shown in the system. the bookshelf layer in the rfid system can be retrieved through the barcode immediately. the map of the reading room has been embedded in the opac. furthermore, the coordinates of the book (x, y, height) can be shown through the bookshelf layer. the index of each bookshelf coordination is created in the opac, rfid system, and lsim. the field of the map presentation is built in the opac, and the search interface is supported by the arcmap and arcscene. the url link is the content of the field, and its content is varied with the different bookshelves. in short, when the reader searches one book, the related bookshelf coordination is highlighted in the map. through the bookshelf layer field, the book information in the query system can be connected with that of lsim. faculty and students can search books in the query system visually. as shown in figure 2, spatial information and attribute information are connected in the lsim. furthermore, a lsim based on gis is built to provide better services for readers and enhance librarians’ visual management. library space information model based on gis | shen 104 https://doi.org/10.6017/ital.v37i3.10308 figure 3. the connection of the opac, rfid system, and lsim. figure 4. finding a book in

query in the reading room when a book about biological medicine is required, it can be searched by using the keyword “biological medicine” in our explore. then, as shown in figure 4, a book titled amalgamation within evolution can be found with the clc call number r318-53/3. readers can find the book with the call number in the corresponding reading room. however, if the lsim is applied, the search results include not only the text information about the book’s location, but also a visual map. firstly, the barcode of the book (32832872) is identified and passed to the bookshelf layer. the bookshelf layer (a4r042c04) will be found in the lsim. then the book’s spatial position can be shown on a visual map. figures 5a and 5b show the 2d and 3d visual position of the book with the call number r318-53/3, and these two results can be switched in the system. the red arrow is the book’s position. based on the visual position, readers can find the book more conveniently. the reading rooms in shanghai jiao tong university library are organized by subject. in each reading room, the books with related categories are distributed together. figures 5a and 5b show the layout of one reading room. the books with the large clc classes, i.e., o, p, q, r, and s, were studied as an example in the reading room in this paper. the red triangles represent chairs and the light green rectangles represents desks. shelves are alphabetically labeled. the reference desk, office area, group study room, storehouse, inquiry machines, printers, and stairs are also shown. special collections in different reading rooms in the shanghai jiao tong university library, there are many special collections, such as contract documents, tsung-dao lee’s manuscripts, alumni theses, important findings of research teams, and so on. because of their rarity, these special collections do not circulate and can only be read in the reading rooms. furthermore, these collections are located in different branch libraries. the geographical information of these resources can be input into the model. scholars can use lsim to achieve the exact positions of these resources, go directly to the related area, and quickly find these special items. library analysis and management book-borrowing situation analysis using gis, it is also possible to show how often books circulate based on their physical location. as shown in figure 6, each rectangle represents a shelf in the reading room. the books with the same topic are placed on the same shelf. the number labeled on the shelf represents the average borrowing frequency of the books on this shelf. different colors mean different frequency, with scale of five to one hundred. the clc classes o, p, and q appearing on the right of the shelves represent mathematical sciences and chemistry, astronomy and geosciences, and bioscience, respectively. information technology and libraries | septmber 2018 107 figure 6. average borrowing frequency of the books on each shelf in one reading room. based on analysis of the relationship between borrowing frequency and subject category, the hot spots of the professional fields can be found and shown. in turn, books related to the hot spots can be recommended to readers. taking class o as an example, the shelf position of the highest borrowing frequency (100) is in row 9, column 2. according to the query system, the theme of the books on this shelf is high polymer chemistry. the books with high borrowing frequency can be highlighted both on the bookshelf and in the query system. if the higher-borrowing-frequency books on the remote shelves meet school discipline development policy, the purchases of these books will be increased. books related to the subjects with the higher borrowing frequency on the taller or lower shelves will also be considered, and vice versa. permanent-assets management permanent assets such as chairs, desks, shelves, inquiry machines, printers, etc., can be managed in this model. information about permanent assets (such as their status, spatial position, etc.) was input in the model, as is shown in figures 5a and 5b. librarians can find the visual positions of permanent assets at any time, and readers can conveniently find the inquiry machines or printers to search books and print documents. library space information model based on gis | shen 108 https://doi.org/10.6017/ital.v37i3.10308 future directions the lsim is only tested in one reading room and is still experimental. this model will be expanded to the whole library, providing visual information of library books and materials. in the process of using this model, gis potentiality in the library will be exploited to provide better services for readers and managers. conclusion based on readers’ need of the book position in the library, the lsim is built to visually show the exact bookshelf layer of the book. spatial and attribute information is combined into the model. based on the model, readers can search for books and find books’ positions. meanwhile, many special collections located in the different branches can be easily found in the model. the gis model not only brings convenience to readers, but also supports the library’s analysis and management. librarians can analyze books’ circulation history based on the relationship between the books’ borrowing frequency and subject categories. books with higher borrowing frequency and ones related them can be recommended to the readers. then the number of the purchased books with the higher borrowing frequency in the remote, taller, or lower places will be increased based on the above analysis. permanent assets can also be managed, and librarians can conveniently find the status and spatial position of the inquiry machines, printers, and so on. in short, the application of gis in the library will bring a visual insight into the library, providing a better reader experience and better library management. acknowledgements i thank guo jing, chen jiayi and huang qinling, shanghai jiao tong university library, for their advice on the structure of this article and the grammar of

internet…today! the elibrary team at the palo alto city library held a vr hackfest weaving together multiple emerging technologies into a single workshop. during the event, participants had hands -on experience building vr scenes, which were loaded to a raspberry pi and published online using the distributed web. throughout the day, participants discussed how these technologies might change our lives, for good and for ill. and afterward, an exhibit showcasing the participants’ vr scenes was placed at our mitchell park branch to stir further conversation. multiple emerging technologies explored the workshop was largely focused around the a-frame code, a framework for publishing 3d scenes to the web (https://aframe.io/). however, we also integrated a number of other technologies, including a raspberry pi, qr codes, a twitter-bot, and the inter-planetary file system (ipfs), which is a distributed web technology. virtual reality built with a-frame code in the vr hackfest, participants first learned how to use a-frame code to render 3d scenes that can be experienced through a web browser or vr headset. a-frame is a new framework that web publishers and 3d designers can use to design web sites, games and 3d art. a-frame is an extension of html, the code used to build web pages. anyone who is familiar with html will pick up a-frame very quickly, but it is simple enough even for beginners. for example, here is some raw a-frame code: <!doctype html> <html> <head> <script src="https://aframe.io/releases/0.9.1/aframe.min.js"></script> </head> <body style='margin: 0px; overflow: hidden;'> <a-scene> <a-box position="0 1 -2" rotation="0 45 45" scale="1 1 1" color="blue"> </a-box> </a-scene> </body> </html> mailto:chris.markman@cityofpaloalto.org

https://doi.org/10.6017/ital.v38i4.11877 figure 1. try this code example! https://tinyurl.com/ipfsvr02. save the above code as an html file and open it with a webvr compatible browser like chrome and you will then see a blue cube in the center of your screen. by just changing the values of a few parameters, novice coders can easily change the shape, size, color and location of primitive 3d objects, add 3d backgrounds and more. advanced users can also insert javascript code to make the 3d scenes more interesting. for example, in the workshop, we provided javascript that animated a 3d robot head (see figure 1) pre-loaded into the codepen (https://codepen.io) interface for quicker editing and iteration. the inter-planetary file system (ipfs) the collection of 3d scenes created in the vr hackfest was published to the internet using the inter-planetary file system (ipfs), an open source distributed web technology originally created in palo alto by protocol labs in 2014 and now actively improved by a global network of software developers. ipfs allows anyone to publish to the internet without a server, through a peer-to-peer network that can also work seamlessly with the regular internet through http “gateways”. in november 2019, brave browser (https://brave.com) became the first to offer seamless ipfs integration, capable of spawning its own background process or daemon that can upload and download to ipfs content on the fly without the need for an http gateway or separate browser extension installation. unlike p2p technologies such as bittorrent, ipfs is best suited for distributing small files available for long periods of time rather than the quick distribution of large files over a short period of time. this is an oversimplification of what is really happening behind the scenes (part of the magic involves content-addressable storage and asynchronous communication methods based on pub/sub messaging, to name a few) but the ability to share and publish 3d environments and 3d objects in a way that can instantly scale to meet demand could have far reaching consequences for future technologies like augmented reality. https://tinyurl.com/ipfsvr02 https://codepen.io/ https://ipfs.io/ https://brave.com/ information technology and libraries | december 2019 8 figure 2. workshop attendees. ipfs can load content much faster, more securely (through features like automated cryptographic hash checking), and allows people to publish directly to the internet without the need of a thirdparty host. google, facebook, and amazon web services need not apply. the same technology has already been used to overcome censorship efforts by governments, but like any technology it has its downsides. content on ipfs is essentially permanent, allowing free speech to flourish but it could also make undesirable content, like hate speech or child pornography, all but impossible to control. toward 21st century literacy like our other technology programs, the vr hackfest was designed to engage customers around new forms of literacy, particularly around understanding code and thinking critically about emerging communication technologies. in 2019, we are already seeing how technologies like machine learning and social media are impacting social relations, politics and the economy. it is no longer enough to know how to read and write code that underlies the web. true literacy must also understand how these technologies interface with each other and how they impact people and society. vr hackfest | markman, hess, lou, and nguyen 9 https://doi.org/10.6017/ital.v38i4.11877 figure 3. the free-standing exhibit. information technology and libraries | december 2019 10 to this end, the vr hackfest sought to take participants on a journey, both technological but also sociological. once the initial practice with the code was completed, we moved on to a discussion of the consequences for using these technologies. with the distributed web, for example, we explored questions like: • what are the implications for permanent content on the web which no one can take down? • what power do gatekeepers like the government and private companies have over our online speech? • what does a 3d web look like and how will that change how we communicate, tell stories and learn? after the workshop ended, we continued the conversation with the public through an exhibit placed at our mitchell park branch (see figure 3). in this exhibit, we showcased the vr scenes participants had created and introduced the technologies underlying them. but we also asked people to reflect on the future of the internet and to share their thoughts by posting on the exhibit itself. public comments reflected the current discourse around the internet. responses (see figure 5) were generally positive—most of our customers mentioned better download speeds or other efficiency increases but a few also highlighted online privacy and safety improvements. we recorded an equal number of pessimistic and technical responses to the same question, these often demonstrated either knowledge of similar technology (e.g. “how is this different than napster?”) or displeasure with the current state of the world wide web (e.g. “less human connections” or “more spyware and less freedom”). outcomes one surprise outcome was that our project reached the attention of the developers of ipfs, who happen to live a few blocks away from the library. after reading about the exhibit online, their whole team visited our team at the library. in fact, one of their team turned out to be a former child customer of our library! the workshop itself, which was featured as a summer reading program activity, also brought in record numbers. originally open to 20 participants and later expanded to 30, the workshop grew a waitlist that more than quadrupled our initial room capacity. clearly, people were interested in learning about these two emerging technologies. we also want to take a moment to highlight the number of design iterations this project went through before making its way into the public eye. the free-standing vr hackfest exhibit was originally conceived as a wall mounted computer kiosk that encouraged users to publish a short message directly to the web with ipfs, but this raised too many privacy concerns and ultimately our building design does not make mounting a computer on the wall an easy task. our workshop also initially focused much more on command line skills working directly with ipfs, but user testing with library staff showed learning a-frame was more than enough. vr hackfest | markman, hess, lou, and nguyen 11 https://doi.org/10.6017/ital.v38i4.11877 figure 4.

because it combined so many different skills into a single project. we were not only working with open source tools and highlighting new technologies, but also building an experience for workshop attendees and showcasing their work to thousands of people. future work our immediate plans include re-use of the exhibit frame for future public technology showcases and offering another round of vr hackfest workshops, perhaps in a smaller group so participants have the chance to view their work while wearing a vr headset. figure 7. 3d mock-up. beyond this, we also think libraries have the opportunity to harness the distributed web for digital collections, potentially undercutting the cost of alternative content delivery networks or file hosting services. through this project we have already tested things like embedded ipfs links in marc records and building a 3d object library. essentially, all the pieces of the “future web” are already here and it is just a matter of time before all modern web browsers offer native support for these new technologies. in general, our project demonstrated the popularity of 21st-century literacy programs. but it also demonstrated the significant technical difficulties of conducting cutting edge technology workshops in public libraries. clearly, the demand is there, and our library will continue to strive to re-imagine library services.

libraries | june 2008 an assessment of student satisfaction with a circulating laptop service louise feldmann, lindsey wess, and tom moothart since may of 2000, colorado state university’s (csu) morgan library has provided a laptop computer lending service. in five years the service had expanded from 20 to 172 laptops. although the service was deemed a success, users complained about slow laptop startups, lost data, and lost wireless connections. in the fall of 2005, the program was formally assessed using a customer satisfaction survey. this paper discusses the results of the survey and changes made to the service based on user feedback. colorado state university (csu) is a land-grant insti-tution located in fort collins, colorado. the csu libraries consist of the morgan library, the main library on the central campus; the veterinary teaching branch hospital library at the veterinary hospital campus; and the atmospheric branch library at the foothills campus. in 1997, morgan library completed a major renovation and expansion which provided a designated space for public desktop computers in an information commons environment. the library called this space the electronic information center (eic). due to the popularity of the eic ,and with the intent of expanding computer access without expanding the computer lab, library staff began to explore the implementation of a laptop checkout service in 2000. library staff used heather lyle’s (1999) article “circulating laptop computers at west virginia university” as a guide in planning the service. development funds were used to purchase twenty laptop computers, and the 3com corporation donated fifteen wireless network access points. the laptops were to be used in morgan library on a wireless network maintained by the library technology services department. these computers were to be circulated from the loan desk, the same desk used to check out books. although the building is open to the public, use of the laptops was limited to university students and staff and for library in-house use only. all the public desktop computers and laptops use microsoft windows and microsoft office. maintaining the security of the libraries’ network and students’ personal data in a wireless environment was paramount. to maintain a secure computing environment and present a standardized computing experience in the library, an application of windows xp group policies was used. currently, the laptop software is updated at least every semester using symantec ghost. ghost copies a standardized image to every laptop even when the library owns a variety of computer models from the same manufacturer. additionally, due to concerns over wireless computer security, morgan library implemented cisco’s virtual private network (vpn) in 2004. the laptop service was launched in may 2000. more than 22,000 laptop transactions occurred in the initial year. since its inception, the use of the morgan library laptop service and the number of laptops available for checkout has steadily grown. using student technology funds, the service had grown to 172 laptops and ten presentation kits consisting of a laptop, projector, and a portable screen. circulation during the fall 2005 semester totaled 30,626 laptops and 102 presentation kits. in fiscal year 2005, 66,552 laptops and presentation kits were checked out. based on the high circulation statistics and anecdotal evidence, the service appeared to be successful. although morgan library replaced laptops every three years and upgraded the wireless network, laptop support staff noted that users complained of slow laptop startups, lost data, and lost wireless connections. the researchers also noted that large numbers of users queued at the circulation desk at 5:00 p.m. even though large numbers of desktop computers were available in the eic. a customer service satisfaction survey was developed to assess the service and test library staff’s assumptions about the service. csu had a student population of 25,616 students at the time of the survey. n literature review much of the published literature discussing laptop services focuses on the implementation of laptop lending programs and was published from 2001 to 2003, when many libraries were beginning this service (allmang 2003; block 2001; dugan 2001; myers 2001; oddy 2002; vaughan and burnes 2002; williams 2003). these articles deal primarily with topics such as how to deal with start-up technological, staffing, and maintenance issues. they have minimal discussion of the service post-implementation. researchers who have surveyed users of university laptop lending services include direnzo (2002), lyle (1999), jordy (1998), block (2001), oddy (2002), and monash university’s caulfield library (2004). direnzo from the university of akron only briefly discusses a survey they conducted with some information about additional software added as a result of their user comments. lyle from west virginia university discusses the percentage of respondents to particular questions such louise feldmann (louise.feldmann@colostate.edu) is the business and economics librarian at colorado state university libraries. she serves as the college liaison librarian to the college of business. lindsey wess (lindsey.wess@colostate. edu) coordinates assistive technology services and manages the information desk and the electronic information center at colorado state university libraries. tom moothart (tmoothar@ library.colostate.edu) is the coordinator of on-site services at colorado state university libraries. student satisfaction with circulating laptop service | feldmann, wess, and moothart 21 as what applications were used, problems encountered, and overall satisfaction with the service. jordy’s report provides in-depth analysis of the survey results from the university of north carolina at chapel hill, but the focus of his survey is on the laptop service’s impact on library employee work flow. monash university’s caulfield library survey focuses on wireless access and awareness of the program by patrons. other survey results found on university library web sites include southern new hampshire university library (west 2005) and murray state university library (2002). additionally, the monmouth university library web site (2003) provides discussion and written analysis of a survey they conducted prior to implementation of their service, a survey which was used to gather information and assess patron needs in order to aid in the construction and planning of their service. from the survey results discussed in the literature and posted on web sites, overall comments from users are very consistent with one another. most users indicate that they use a loaned laptop computer rather than desktop computer for privacy and portability (lyle 1999; oddy 2002; west 2005). in addition, the responses from patrons are overwhelmingly positive and users appreciated having the service made available (lyle 1999; jordy1998; west 2005). both west virginia university and the university of north carolina at chapel hill surveys found that 98 percent of respondents would check out a laptop again (lyle 1999; jordy 1998). southern university of new hampshire’s survey indicated that 88 percent of those responding would check one out again (west 2005). many respondents stated that a primary drawback of using the laptops was the slowness of connectivity (lyle 1999; monash 2004; murray state 2002). the primary use of the laptops, reported in the surveys, was microsoft word (lyle 1999; jordy 1998; oddy 2002). there is a lack of published literature regarding laptop lending customer satisfaction surveys and analysis. this could be due to the relative newness of many programs, the lack of university libraries that provide laptops, or the reliance on circulation statistics solely to assess the program. articles that discuss circulation and usage statistics as an assessment indicator to judge the popularity of their programs include direnzo (2002), dugan (2001), and vaughan and burnes (2002). based on high circulation statistics and positive anecdotal evidence, it may appear that library users are pleased with laptop programs, and perhaps there has been a hesitation to survey users on a program that is perceived by those in the library as successful. n results with the strong emphasis on assessment at colorado state university, it was decided to formally survey laptop users on their satisfaction with the program. the survey was distributed by the access services staff when the laptops were checked out from october 28, 2005, to november 28, 2005. this was a voluntary survey and the respondents were asked to complete one survey. users returned 173 completed surveys. undergraduates are the predominant audience for the laptop service; of the 173 returned surveys, 160 identified themselves as undergraduates. as shown in table 1, the responses indicated that the library has a core of regular laptop users, with 33 percent using the laptops at least daily and 82 percent using the laptops at least weekly. only 3 percent indicated that they were using a laptop for the first time. many laptop users also utilized the eic with 67 percent responding that they use the information commons at least weekly (see table 2). the laptops were initially purchased with the intent that they would be used to support student team projects. presentation kits with a laptop, projector, and portable screen were an extension of this idea and were also made available for checkout. surprisingly, only 15 percent of table 1. how often do you use a library laptop? frequency percentage more than once a day 3% daily 30% weekly 49% monthly 15% my first time 3% n=172 table 2. how often do you use a library pc? frequency percentage more than once a day 3% daily 20% weekly 44% monthly 20%

regularly queuing and waiting for a laptop even though pcs were available in the library computer lab. figure 1 shows an hourly use statistics for the desktop and laptop public computers. the usage of the desktop computer drops in the late afternoon, just as the use of the laptop computer increases. students were asked why they chose a laptop rather than a library pc and were allowed to choose from multiple answers. as can be seen in table 3, most students noted the advantages of portability and privacy. five respondents wrote in the “other” category that they were able to work better in quieter areas, and ten mention that the computer lab workspace is limited. the dense use of space in the library computer lab has been noted by morgan library staff and students. the desktop surrounding each library pc only provides about three feet of workspace. one respondent explained the choice of laptop over pc was because “i can take it to a table and spread out my notes vs. on a library pc.” for many users, the desktops are too crowded to spread research material, and the eic is too noisy for contemplative thought. as can be noted from the use statistics, the public laptop program has been a very popular library service. prior to the survey, the perception of the morgan library staff was that students were waiting in the evening for extended periods of time for a laptop. when the library expanded the laptop pool from 20 in 2000 to 172 in 2005, it had seemingly no effect on reducing the number of students waiting to use them. as can be seen in table 4, when asked how long they had waited for a laptop, 74 percent of the students said they had access to a laptop immediately, and 15 percent waited less than a minute. the survey was administered during the second busiest time of the year for the library, the month before thanksgiving break. in the open comments, one respondent stated that it was possible to wait fortyfive minutes to an hour for a laptop and another noted that “during finals weeks it is almost impossible to get one.” even with the limited waiting time recorded by the page 1 of 1 feldmann figures.doc 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 7:30 am 8:30

circulating laptop service | feldmann, wess, and moothart 23 respondents, when asked how the library could improve the laptop service many respondents requested that more laptops be purchased to decrease the wait. the library is struggling to determine the appropriate number of laptops to have available during peak use periods to reduce or eliminate wait times. the library laptops are more problematic than the library desktop computers to support. the laptops are more fragile than the desktop computers and have the added complication of connecting to the wireless network. every morning the morgan library’s technology staff retrieves non-functioning laptops; library technicians regularly retrieve lost data due to malfunctioning laptops and unsophisticated computer users. the addition of the virtual private network (vpn) connection to the laptop startup script files has slowed the boot-up to the wireless network. an effort has been made to ameliorate wireless “dead zones,” but users still complain of being dropped from the wireless network. with these problems in mind, users were asked about the technical complications they have experienced with the library laptops. the survey responses in tables 5 and 6 indicate a much lower percentage of users reporting technical problems than was anticipated. the technical staff’s large volume of technical calls may reflect the volume of users rather than systematic problems with the laptop service. surprisingly, 79 percent of the users reported rarely or never returning a non-functioning laptop. in addition, the library technicians have reported that no problems have been found on some of the laptops returned for repair. some of the returned computers may be due to frustration with the slow connection to the wireless network. forty-five percent of respondents reported at least occasionally having problems connecting to the wireless network. from the inception of the laptop program, the library has experienced problems with the wireless technology. from its original fifteen wireless access points to its current twenty-nine, the library has struggled to meet the demand of additional library laptops and users’ personal laptops. many written comments on the surveys complained about the slow connection speed of the wireless network such as, “find a way to make the boot-up process faster. i need to wait about five minutes for it to be totally booted and ready to use.” even with the slow connection to the wireless network, 41 percent of students responding to the survey rated their satisfaction with the library’s laptop service as excellent and 49 percent rated their satisfaction as good (see table 7). n discussion even with 90 percent of our users rating the laptop service as good or excellent, the survey noted some problems that needed attention. the morgan library laptops seamlessly connect to a wireless network through a login script when the computer is turned on. a new script was written to table 4. how long did you wait before you were able to check out your laptop? response percentage i did not wait 74% less than one minute 15% one to four minutes 11% five to ten minutes 2%

virtual private network (vpn) client. during testing it was found that some laptops took as long as ten minutes to connect to the wireless network, which resulted in numerous survey respondents commenting on our slow wireless network. to help correct this problem, the library’s network staff changed each laptop’s user profile from a mandatory roaming profile to a local profile and simplified the login script. the laptops connected faster to the wireless network with the new script, but they still did not meet the students’ expectations. in the fall of 2006, the library network staff moved the laptops from vpn to wi-fi protected access (wpa) wireless security, and laptop login time to the wireless network dropped to under two minutes. the number of customer complaints dropped dramatically after implementing wpa. additional access points were purchased to improve connectivity in morgan library’s wireless “dead zones.” in january 2006, the university’s central computing services audited the wireless network after continued wireless connectivity complaints. the audit recommended reconfiguring the access points channel assignments. in many cases it was found that the same channel had been assigned to access points adjacent to each other, ultimately compromising laptop connectivity. the audit also discovered noise interference on the wireless network from a 2.4-ghz cordless phone used by the loan desk staff. the phone was replaced with a 5.8-ghz one, which has resulted in fewer dropped connections near the loan desk. supporting almost 200 laptops has introduced several problems in the library. the morgan library building was not designed to support the use of large numbers of laptops. because it is impractical for the loan desk to charge nearly 200 laptop batteries throughout the day, laptops available for checkout must be connected to electrical outlets. these are seldom near study tables, and students are forced to crawl underneath tables to locate power or stretch adapter cords across aisles. a space plan for the morgan library is being developed that will increase the number of outlets near study tables. in the meantime, 100 power strips were added to tables used heavily by laptop users. the loan desk staff is very efficient at circulating, but has less success at troubleshooting technical problems. when the laptop service was first implemented, large numbers of laptops were not available due to servicing reasons. the public laptop downtime was lowered by hiring additional library technology students. a one-day onsite repair service agreement was purchased from the manufacturer which resulted in many equipment repairs being completed within 48 hours. in order to reduce the downtime further, a plan to replace some loan desk student workers with library technology students is being evaluated. the technology students will be able to troubleshoot connectivity and hardware problems with the users when they return the defective computers to the loan desk. if a computer needs additional service, it can be handled immediately, which will allow more laptops for checkout since fewer will be removed for repair. when the laptop service was first envisioned, it was seen as a great service for those working in groups. as can be seen in table 3, very few students are using the laptops in a group setting. in survey written comments, students emphasize that they enjoy the portability and privacy enabled by using a laptop. the morgan library eic is cramped and noisy, with the configuration allowing very little room for students to spread out research materials and notes for writing. the morgan library space plan takes these issues into consideration and recommends reconfiguring the eic to lessen the noise and provide writing space near computers. this is intended to improve the student library experience and encourage students to use the desktop computers during the evenings when lines form for the laptops. in order to decrease the current laptop queue at the loan desk, more laptops will be added. as a result of survey comments requesting apple computers, five mac powerbooks were added to the library’s laptop fleet. in addition, as morgan library adds more checkout laptops and the number of students arriving on campus with wireless laptops increases, the wireless infrastructure will need to be upgraded. upgrading the wireless access points to standard 802.11g has been implemented. updating each laptop with a new hardrive image has become problematic as the number of laptops has increased. the wireless network capacity is not large enough for the ghost software to transmit the image to multiple laptops, and so each laptop must be physically attached to the library network. initially, when library technology services attempted imaging many laptops at once, it took six to eight hours and required up to eight staff members. this method of large-scale laptop imaging was so network intensive that it had to be performed when the library was closed to avoid disrupting table 7. please rate your satisfaction with the laptop service. response percentage excellent 41% good 49%

twenty to thirty laptops at a time, in order to minimize complications with the ghost process and multicasting through the network switches. due to the staff time required, laptop software is not updated as often as the users would like. technological solutions continue to be investigated that will decrease the labor and network intensity of imaging. n conclusion the morgan library laptop service was established in 2000 and has been a very popular addition to the library’s services. as an example of its popularity, in fiscal year 2005 the laptops circulated 66,552 times. student government continues to support the use of student technology fees to support and expand the fleet of laptops. this survey was an attempt to assess users’ perceptions of the service and identify areas that need improvement. the survey found that students rarely wait more than a few minutes for a laptop, and in open-ended survey questions, students noted that they waited for computers only during peak use periods. while relatively few survey respondents experienced technical difficulties with the laptops and wireless network, slow wireless connection time was a concern that students noted in the open comments section of the survey. overall, the students gave the laptop service a very high rating. when asked to suggest improvements to the service, many respondents recommended purchasing more laptops. the libraries made several changes to improve the laptop service based on survey responses. changes have been made to the login script files, wireless network, and security protocol to speed and stabilize the wireless connection process. additional wireless access points will be added to the building and all access points will be upgraded to the 802.11g standard. in addition, five mac powerbooks have been added to the fleet of windowsbased laptops. the library continues to investigate new service models to circulate and maintain the laptops. works cited allmang, nancy. 2003.

publishing large, high-resolution images on the web. end users view these images with existing webbrowser software as quickly as they do normal, downsampled images. a flash-based zoomifyer client asynchronously streams image data to the web browser as needed, resulting in response times approaching those of desktop applications using minimal bandwidth. the author, a librarian at cornell university and the principal architect of a small, open-source company, worked closely with zoomify to produce a cross-platform, opensource implementation of that company’s image-processing software and discusses how to easily deploy the product into a widely used webpublishing environment. limitations are also discussed as are areas of improvement and alternatives. z oomifyer from zoomify (www .zoomify.com) enables users to view large, high­resolu­ tion images within existing web­ browser software while providing a rich, interactive user experience. a small zoomifyer client, authored in macromedia flash, is embedded in an html page and makes asyn­ chronous requests to the server to stream image data back to the client as needed. by streaming the image data in this way, the image renders as quickly as a normal, downsampled image, even for images that are giga­ bytes in size. as the user pans and zooms, the response time approaches that of desktop applications while using the smallest possible band­ width necessary to render the image. and because flash has 98.3 per­ cent browser saturation, viewing “zoomified” images is seamless for most users and allows them to view images interactively in much greater detail than would otherwise be prac­ tical or even possible.1 zoomify image (sourceforge.net/ projects/zoomifyimage) was created at cornell university in collabora­ tion with zoomify to create an open­ source, cross­platform, and scriptable version of the processing software that creates the image data displayed in a zoomifyer client. this work was immediately integrated into an inno­ vative content­management system that was being developed within the zope application server, a premier web application and publishing plat­ form. authors in this system can add high­resolution images just as they normally add downsampled images, and the image is automat­ ically processed on the server by zoomify image and displayed within a zoomifyer client. zoomify image is now in its second major release on source forge and contains user con­ tributed software to easily deploy it in other environments such as php. zoomifyer has been used in a number of applications in many fields, and can greatly enhance many research and instructional activities. applying zoomifyer to digital­image collections is obvious, allowing libraries to deliver an unprecedented level of detail in images published to the web. new applications also suggest themselves, such as serving high­resolution images taken from tissue samples in a medical lab or using zoomifyer in advanced geo­ spatial image applications, particu­ larly when advanced client features such as annotations are used. the zoomifyer approach also has positive implications for preservation and copyright protection. zoomify image generates cached derivatives of master image files so the image masters are never directly accessed in the application or sent over the internet. image data are stored and transmitted to the client in small chunks so that end users do not have access to the full data of the original image. deploying zoomify image dependencies and winstallation zoomify image was designed ini­ tially to be a faithful, cross­platform port of zoomify’s image­processing software. it was developed in close cooperation with zoomify to pro­ vide a scriptable method for invok­ ing the image­preparation process for zoomifyer clients so this technol­ ogy could be used in more environ­ ments. zoomify image is written in the python programming language and uses the third­party python imaging library (pil) with jpeg support, both of which are also open source and cross­platform. it has been tested in the following environments: ■ python 2.1.3 ■ pil 1.1.3 and ■ python 2.4.3 ■ pil 1.1.4 installers for python and pil exist for all major platforms and can be obtained at python.org and www .pythonware.com/products/pil. the installation documentation that comes with pil will help you locate the appropriate jpeg libraries if they are missing from your system. for macosx, you can find pre­built binary installers for python, pil and zope at sourceforge.net/projects/ mosxzope. introducing zoomify image adam smith adam smith (ajs17@cornell.edu) is a systems librarian at cornell university library, ithaca, new york. introducing zoomify image | smith 4�introducing zoomify image | smith 4� the “ez” version of the zoomifyer client, a flash­based applet with basic pan and zoom functionality, is pack­ aged with zoomify image for conve­ nience so the software can be used immediately once installed. the ez client is covered by a separate license and can be easily replaced with more advanced clients from zoomify at www.zoomify.com. (a description of how to upgrade the zoomifyer client is included in this paper.) after python and pil with jpeg support are installed, download the zoomify image software from sourceforge.net/projects/zoomify­ image and decompress it. using zoomify image from the command line begin exploring zoomify image by invoking it on the command line: python <your_path>/zoomifyfilepr ocessor.py <your_image_file> or, to process more than one file at a time: python <your_path>/zoomifyfile processor.py <image_1> <image_2> <image_3> the file format of the images input to zoomify image are typically either tiff or jpeg, but can be any of the many formats that pil can read.2 an image called “test.jpg” is included in the zoomify image distribution and is of sufficient size and complexity to provide an interesting example. during processing, zoomify image creates a new directory to hold the converted image data in the same location as the image file being processed. the name of this direc­ tory is based on the file name of the image being processed, so that, for example, an image called “test.jpg” would have a corresponding folder called “test” containing the converted image data used by the zoomifyer client. if the image file has no file extension, the directory is named by appending “_data” to the image name, so that an image file named “test” would have a corresponding directory called “test_data.” if the process is re­run on the same images, any previously generated data are automatically deleted before being regenerated. zoomify provides substantial documentation and sample code on its web site that demonstrates how to use the data generated by zoomify image in several environments. user­ contributed code is bundled with zoomify image itself, further dem­ onstrating how to dynamically incor­ porate this conversion process into several environments. an example of the use of zoomify image within the zope application server is given. incorporating zoomify image into the zope application server the popular zope application server contains a number of built­in services including a web server, ftp and webdav servers, plug­ins for access­ ing relational databases, and a hier­ archical object­oriented database that uses a file­system metaphor for stor­ age. this object database provides a unique opportunity to incorporate zoomifyer into zope seamlessly. to use zoomify image with zope, the distribution must be decom­ pressed into your zope products directory. for versions 2.7.x and up, this is at: <zope_instance_home>/products/ in zope versions prior to the 2.7.x series, the products directory is at: <zope_home>/lib/python/ products/ restart zope and now within the web­based zope management interface (zmi), the ability to add zoomify image objects appears. after selecting this option, a form is presented that is identical to the form used for adding ordinary image objects within zope. when an image is uploaded using this form, zope automatically invokes the zoomify image conversion process on the server and links the generated data to the default zoomifyer client that comes with the distribution. if the image is subsequently edited within zmi to upload a new version, any existing conversion data for that image are automatically deleted, and the new conversion data are gener­ ated to replace them, just as when invoked on the command line. again, the uploaded image can be in any format that zope recognizes as having a content­type of “image/...” and that pil can read. the only potential “gotcha” in this process is that in the versions of the zoomifyer client the author has tested, zoomify image objects that have file names (in zope terminology, the file name is the object’s “id” property) with extensions other than “.jpg” are not displayed properly by the zoomifyer client. so, when uploading a tiff image, for example, the id given to the zoomify image object should either not contain an extension, or it should be changed from image.tif to something like image_tif. this bug has been reported to zoomify and may be fixed in newer versions of the flash­based viewing software at the time of publication. to view the image within the zoomifyer client, simply call the “view” method of the object from within a browser. so, for a zoomify image object uploaded to: http://<your_domain>/test/test.jpg go to this url: http://<your_domain>/test/test. jpg/view or, to include this view of the image within a zope page template 50 information technology and libraries | march 200750 information technology and libraries | march 2007 (zpt), simply call the tag method of the zoomify image just as you would a normal image object in zope. so, in a zpt, use this: <tal:block replace=”here/test.jpg/ tag” /> it is possible that the zoomify image conversion process will not have had time to complete when someone tries to view the image. the zoomify image object will attempt to degrade gracefully in this situation by trying to display a downsampled version of the image that is gener­ ated part way through the conver­ sion process, or, if that is also not available, finally informing the user that the image is not yet ready to be viewed. this logic is built into the tag method. to add larger images more effi­ ciently, or to add images in bulk, the zoomify image distribution contains detailed documentation to quickly configure zope to accept images via ftp or webdav and automatically process them through zoomify image when they are uploaded. finally, the default zoomifyer cli­ ent can be overridden by uploading a custom zoomifyer client into a loca­ tion where the zoomify image object can “acquire” it, and giving it a zope id of “zoomifyclient.swf”. how it works to be viewed by a zoomifyer cli­ ent, an image must be processed to produce tiles of the image at differ­ ent scales, or tiers. an xml file that describes these tiles is also necessary. zoomify image provides a cross­ platform method of producing these tiled images and the xml file that describes them. beginning at 100­percent scale, the image is successively scaled in half to produce each tier, until both the width and height of the final tier are, at most, 256 pixels each. each tier is further divided into tiles that are, at most, 256 pixels wide by 256 pixels tall, as seen in figure 1. these tiles are created left to right, top to bottom. tiles are saved as images with the naming conven­ tion indicated in figure 2. the numbering is zero­based, so that the smallest tier is represented by one tile that is at most 256 x 256 pixels wide with the name “0­0­ 0.jpg.” tiles are saved in directories in groups of 256, and those directories also follow a zero­based naming con­ vention starting with “tilegroup0.” lower­numbered tile groups contain lower­numbered tiles, so 0­0­0.jpg is always in tilegroup0. zoomifyer clients understand this tile­naming scheme and only request tiles from the server that are necessary to stitch together the por­ tion of the image being viewed at a particular scale. limitations zoomify image was developed to meet two goals: 1. to provide a cross­platform port of the zoomifyer con­ figure 1. tiers and tiles for a 2048 x 2048 pixel image figure 2. tile image naming scheme introducing zoomify image | smith 51introducing zoomify image | smith 51 verter for use in unix/linux systems, and 2. to make the converter script­ able, and ultimately integrate it into open­source content­man­ agement software, particularly zope. this zoomifyer port was writ­ ten in python, a mature, high­level programming language with an execution model similar to java. although zoomify image continues to be optimized, compared to the official zoomify conversion software, it is slower and more limited in the sizes of images it can reasonably process. anecdotally, zoomify image has been used effectively on images hundreds of megabytes large, but significant performance degradation has been reported in the multi­giga­ byte range. because of these limitations in zoomify image, the official zoomify image­processing software is recom­ mended for converting very large images manually in a windows or macintosh environment. the zoomify image product is recommended in the following circumstances: ■ the conversion must be per­ formed on a unix/linux machine. ■ the conversion process must be scriptable, such as for batch pro­ cessing or being run dynamically. ■ images sizes are not in the multi­ gigabyte range. if a scriptable, cross­platform version of the zoomifyer converter is needed, but performance is an issue, several things can be done to extend the current limits of the soft­ ware. obviously, upgrading hard­ ware, particularly ram, is effective and relatively inexpensive. running the latest versions of python and pil will also help. each new version of python makes significant perfor­ mance improvements, and this was a primary goal of version 2.5, which was released in september 2006. the author believes that the cur­ rent weak link in the performance chain is related to how zoomify image is loading image data into memory with pil during processing. in the current distribution, a python script contributed by gawain avers, which is based partially on the zoomify image approach, uses imagemagick instead of pil for image manipula­ tion and is better able to process multi­gigabyte images. the author would like to add the ability to des­ ignate the image library at runtime in future versions of zoomify image. future development beyond improving the performance of the core­processing algorithm, the author would also like to explore opportunities for more efficiently processing images within zope, such as spawning a background thread for processing images so the zope web server can immediately respond to the client’s image­submission request. the author would also like to improve the tag method to display data more flexibly in the zoomifyer client and ensure consistent behav­ ior with zope’s default image tag method. finally, zoomify image could also benefit from the addi­ tion of a simple configuration file to control such runtime properties as image quality and which third­party image­processing library to use, for example. conclusion zoomify image is mature, open­ source software that makes it pos­ sible to publish large, high­resolution images to the web. it is designed to be convenient to use in a variety of architectures and can be viewed within existing browser software. download it for free, begin using it in minutes, and explore its unique possibilities. references 1. adobe systems, macromedia flash player statistics,

digital preservation | kastellec 63 abstract this paper examines factors that limit the ability of institutions to digitally preserve the cultural heritage of the modern era. the author takes a wide-ranging approach to shed light on limitations to the scope of digital preservation. the author finds that technological limitations to digital preservation have been addressed but still exist, and that non-technical aspects—access, selection, law, and finances—move into the foreground as technological limitations recede. the author proposes a nested model of constraints to the scope of digital preservation and concludes that costs are digital preservation’s most pervasive limitation. introduction imagine for a moment what perfect digital preservation would entail: a perfect archive would capture all the content generated by humanity instantly and continuously. it would catalog that information and make it available to users, yet it would not stifle creativity by undermining creators’ right to control their creations. most of all, it would perfectly safeguard all the information it ingested eternally, at a cost society is willing and able to sustain. now return to reality: digital preservation is decidedly imperfect. today’s archives fall far short of the possibilities outlined above. much previous scholarship debates the quality of different digital preservation strategies; this paper looks past these arguments to shed light on limitations to the scope of digital preservation. what are the factors that limit the ability of libraries, archives, and museums (henceforth collectively referred to as archival institutions) to digitally preserve the cultural heritage of the modern era? 1 i first examine the degree to which technological limitations to digital preservation have been addressed. next, i identify the non-technical factors that limit the archival of digital objects. finally, i propose a conceptual model of limitations to digital preservation. technology any discussion of digital preservation naturally begins with consideration of the limits of digital preservation technology. while all aspects of digital preservation are by definition related to technology, there are two purely technical issues at the core of digital preservation: data loss and technological obsolescence. 2 many things can cause data loss. the constant risk is physical deterioration. a digital file consists at its most basic level as binary code written to some form of mike kastellec (makastel@ncsu.edu) is libraries fellow, north carolina state university libraries, raleigh, nc. mailto:makastel@ncsu.edu information technology and libraries | june 2012 64 physical media. just like analog media (paper, vinyl recordings), digital media (optical discs, hard drives) are subject to degradation at a rate determined by the inherent properties of the medium and environment in which it is stored. 3 when the physical medium of a digital file decays to the point where one or more bits lose their definition, the file becomes partially or wholly unreadable. other causes of data loss include software bugs, human action (e.g., accidental deletion or purposeful alteration), and environmental dangers (e.g., fire, flood, war). assuming a digital archive can overcome the problem of physical deterioration, it then faces the issue of technological obsolescence. binary code is simply a string of zeroes and ones (sometimes called a bitstream)—like any encoded information, this code is only useful if it can be decoded into an intelligible format. this process depends on hardware, used to access a bitstream from a piece of physical media, and software, which decodes the bitstream into an intelligible object, such as a document or video displayed on a screen, a printout, or an audio output. technological obsolescence occurs when either the hardware or software needed to render a bitstream usable is no longer available. given the rapid pace of change in computer hardware and software, technological obsolescence is a constant concern. 4 most digital preservation strategies involve staying ahead of deterioration and obsolescence by copying data from older to current generations of file formats and storage media (migration) or by keeping many copies that are tested against one another to find and correct errors (data redundancy). 5 other strategies to overcome obsolescence include pre-emptively converting data to standardized formats (normalization) or avoiding conversion and instead using virtualized hardware and software to simulate the original digital environment needed to access obsolete formats (emulation). as may be expected of a young field, 6 there is a great deal of debate over the merits of each of these strategies. to date, the arguments mostly concern the quality of preservation, which is beyond the scope of this work. what should not be contentious is that each strategy also imposes limitations on the potential scale of digital preservation. migration and normalization are intensive processes, in the sense that they normally require some level of human interaction. any human-mediated process limits the scale of an archival institution’s preservation activities, as trained staffs are a limited and expensive resource. emulation postpones the processing of data until it is later accessed, potentially allowing greater ingest of information. as a strategy, however, it remains at least partly theoretical and untested, increasing the possibility that future access will be limited. data redundancy deserves closer examination, as it has emerged as the gold standard in recent years. the limitations data redundancy imposes on digital preservation are two-fold. the first is that simple maintenance of multiple copies necessarily increases expenses, therefore—given equal levels of funding—less information can be preserved redundantly than can be preserved without such measures. (cost considerations are inextricably linked to every other limitation on digital preservation and are examined in greater detail in “finances,” below.) there are practical, technical limitations on the bandwidth, disk access, and processing speeds needed to perform practical limits to the scope of digital preservation | kastellec 65 parity checks (tests of each bit’s validity) of large datasets to guard against data loss. pushing against these limitations incurs dramatic costs, limiting the scale of digital preservation. current technology and funding are many orders of magnitude short of what is required to archive the amount of information desired by society over the long term. 7 the second way technology limits digital preservation is more complex—it concerns error rates of archived data. non-redundant storage strategies are also subject to errors, of course. only redundant systems have been proposed as a theoretical solution to the technological problem of digital preservation, 8 though, so it is necessary to examine their error rate in particular. on a theoretical level, given sufficient copies, redundant backup is all but infallible. in practice, technological limitations emerge. 9 the number of copies required to ensure perfect bit preservation is a function of the reliability of the hardware storing each copy. multiple studies have found that hardware failure rates greatly exceed manufacturers’ claims. 10 rosenthal argues that, given the extreme time spans under consideration, storage reliability is not just unknown but untestable. 11 he therefore concludes that it cannot be known with certainty how many copies are needed to sustain acceptably low error rates. even today’s best digital preservation technologies are subject to some degree of loss and error. analog materials are also inevitably subject to deterioration, of course, but the promise of digital media leads many to unrealistic expectations of perfection. nevertheless, modern digital preservation technology addresses the fundamental needs of archival institutions to a workable degree. technological limitations to digital preservation still exist but the aspects of digital preservation beyond purely technical considerations—access, selection, law, and finances— should gain greater relative importance than they have in the past. access with regard to digital preservation, there are two different dimensions of access that are important. at one end of a digital preservation operation, authorized users must be able to access an archival institution’s holdings and unauthorized users restricted from doing so. this is largely a question of technology and rights management—users must be able to access preserved information and permitted to do so. this dimension of access is addressed in the technology and law sections of this paper. the other dimension of access occurs at the other end of a digital preservation operation: an archival institution must be able to access a digital object to preserve it. this simple fact leads to serious restrictions on the scope of digital preservation because much of the world’s digital information is inaccessible for the purposes of archiving by libraries and archives. there are a number of reasons why a given digital object may be inaccessible. large-scale harvesting of webpages requires automated programs that “crawl” the web, discovering and capturing pages as they go. web crawlers cannot access password-protected sites (e.g., facebook) and database-backed sites (all manner of sites, including many blogs, news sites, e-commerce sites, information technology and libraries | june 2012 66 and countless collections of data). this inaccessible portion of the web is estimated to dwarf the readily accessible portion by orders of magnitude. there is also an enormous amount of inaccessible digital information that is not part of the web at all, such as emails, company intranets, and digital objects created and stored by individuals. 12 additionally, there is a temporal limit to access. some digital objects only are accessible (or even exist) for a short window of time, and all require some measure of active preservation to avoid permanent loss. 13 the lifespans of many webpages are vanishingly short. other pages, like some news items, are publicly accessible for a short window before they are hidden behind paywalls. even long-lasting digital objects are often dynamic: the ads accompanying a webpage may change with each visit; news articles and other documents are revised; blog posts and comments are deleted. if an archival institution cannot access a digital object quickly or frequently enough, the object cannot be archived, at least not completely. large-scale digital preservation, which in practice necessarily relies on periodic automated harvesting of content, is therefore limited to capturing snapshots of the changes digital objects undergo over their lifespans. law existing copyright law does not translate well to the digital realm. leaving aside the complexities of international copyright law, in the united states it is not clear, for example, whether an archival institution like the library of congress is bound by licensing restrictions and if it can require deposit of digital objects, nor whether content on the web or in databases should be treated as published or unpublished. 14 “many of the uncertainties come from applying laws to technologies and methods of distribution they were not designed to address.” 15 a lack of revised laws or even relevant court decisions significantly impacts the potential scale of digital preservation, as few archival institutions will venture to preserve digital objects without legal protection for doing so. given this unclear legal environment, efforts at large-scale digital preservation are hampered by the need to secure permission to archive from the rights holder of each piece of content. 16 this obviously has enormous impact on preserving the web, but even scholarly databases and periodical archives may not hold full rights to all of their published content. additionally, a single digital object can include content owned by any number of authors, each of whose permission is needed for legal archival. without stronger legal protection for archival institutions, the scope of digital preservation is severely limited by copyright restrictions. digital preservation is further limited by licensing agreements, which can be even more restrictive than general copyright law. frequently, purchase of a digital object does not transfer ownership to the end-user, but rather grants limited licensed access to the object. in this case, libraries do not enjoy the customary right of first sale that, among other things, allows for actions related to preservation that would otherwise breach copyright. 17 preservation of licensed works requires that libraries either cede archival responsibility to rights practical limits to the scope of digital preservation | kastellec 67 holders, negotiate the right to archive licensed copies, or create dark archives that preserve objects in an inaccessible state until their copyright expires. selection the limitation selection imposes on digital preservation hinges on the act of intellectual appraisal. the total digital content created each year already outstrips the total current storage capacity of the world by a wide margin. 18 it is clear libraries and archives cannot preserve everything so, more than ever, deciding what to preserve is critical. 19 models of selection for digital objects can be plotted on a scale according to the degree of human mediation they entail. at one end, the selective model is closest to selection in the analog world, with librarians individually identifying digital objects worthy of digital preservation. at the other end of the scale, the whole domain model involves minimal human-mediation, with automated harvesting of digital objects. the collaborative model, in which archival institutions negotiate agreements with publishers to deposit content, falls somewhere between these two extremes, as does the thematic model, which can apply either selectiveor whole-domain-type approaches to relatively narrow sets of digital objects defined by event, topic, or community. each of these approaches results in limits to the scope of digital preservation. the human mediation of the selective model limits the scale of what can be preserved, as objects can only be acquired as quickly as staff can appraise them. the collaborative and thematic models offer the potential for thorough coverage of their target but by definition are limited in scope. the whole domain model avoids the bottleneck of human appraisal but, more than any other model, is subject to the access limitations discussed above. whole domain harvesting is also essentially wasteful, as it is an anti-selection approach—everything found is kept, irrespective of potential value. this wastefulness makes the whole domain model extremely expensive because of the technological resources required to manage information at such a scale. finances the ultimate limiting factor is financial reality. considerations of funding and cost have both broad and narrow effects. the narrow effects are on each of the other limitations previously identified— financial constraints are intertwined with the constraints imposed by technology, access, law, and selection. the technological model of digital preservation that offers the highest quality and lowest risk, redundant offsite copies, also carries hard-to-sustain costs. while the cost of storage continues to drop, hardware costs actually make up only a small percentage of the total cost of digital preservation. power, cooling, and—for offsite copy strategies—bandwidth costs are significant and do not decrease as scale increases to the same degree that storage costs do. cost considerations similarly fuel non-technical limitations: increased funding can increase the rate at which digital objects are accessed for preservation and can enable development of systems to mine deep web resources. selection is limited by the number of staff who can evaluate objects or information technology and libraries | june 2012 68 the need to develop systems to automate appraisal. negotiating perpetual access to objects or arranging to purchase archival copies creates additional costs. the broad financial effect is that any digital preservation requires dedicated funding over an indefinite timespan. lavoie outlines the problem: much of the discussion in the digital preservation community focuses on the problem of ensuring that digital materials survive for future generations. in comparison, however, there has been relatively little discussion of how we can ensure that digital preservation activities survive beyond the current availability of soft-money funding; or the transition from a project's first-generation management to the second; or even how they might be supplied with sufficient resources to get underway at all. 20 there are many possible funding models for digital preservation, 21 each with their own limitations. creators and rights holders can preserve their own content but normally have little incentive to do so over the long-term, as demand for access slackens. publicly funded agencies can preserve content, but they may lack a clear mandate for doing so, and they are chronically underfunded. preservation may be voluntarily funded, as is the case for wikipedia, although it is not clear if there is enough potential volunteer funding for more than a few preservation efforts. fees may support preservation, either through charging users for access or by third-party organizations charging content owners for archival services; in such cases, however, fees may also discourage access or provision of content, respectively. a nested model of limitations these aspects can be seen as a series of nested constraints (see figure 1). practical limits to the scope of digital preservation | kastellec 69 figure 1. nested model of limitations at the highest level, there are technical limitations on how much digital information can be preserved at an acceptable quality. within that constraint, only a limited portion of what could possibly be preserved can be accessed by archival institutions for digital preservation. next, within that which is accessible, there are legal limitations on what may be archived. the subset defined by technological, access, and legal limitations still holds far more information than archival institutions are capable of archiving, therefore selection is required, entailing either the limited quality of automated gathering or the limited quantity of human-mediated appraisal. finally, each of these constraints is in turn limited by financial considerations, so finances exert pressure at each level. conclusion it is possible to envision alternative ways to model these series of constraints—the order could be different, or they could all be centered on a single point but not nested within each other. thus, undue attention should not be given to the specific sequence outlined above. one important conclusion that may be drawn, however, is that the identified limitations are related but distinct. the preponderance of digital preservation research to date has understandably focused on overcoming technological limitations. with the establishment of the redundant backup model, which addresses technological limitations to a workable degree, the field would be well served by greater efforts to push back the non-technical limitations of access, law, and selection. the other conclusion is that costs are digital preservation’s most pervasive limitation. as rosenthal plainly states it, “society’s ever-increasing demands for vast amounts of data to be kept for the future are information technology and libraries | june 2012 70 not matched by suitably lavish funds.” 22 if funding cannot be increased, expectations must be tempered. perhaps it has always been the case, but the scale of the digital landscape makes it clear that preservation is a process of triage. for the foreseeable future, the amount of digital information that could possibly be preserved far outstrips the amount that feasibly can be preserved. it is useful to put the advances in digital preservation technology in perspective and to recognize that non-technical factors also play a large role in determining how much of our cultural heritage may be preserved for the benefit of future generations. references and notes 1. issues specific to digitized objects (i.e., digital versions of analog originals) are not specifically addressed herein. technological limitations apply equally to digitized and born-digital objects, however, and the remaining limitations overlap greatly in either case. 2. francine berman et al., sustainable economics for a digital planet: ensuring long-term access to digital information (blue

http://www.dlib.org/dlib/march08/lavoie/03lavoie.html digitization has bestowed upon librarians and archivists of the late 20th and early 21st centuries the opportunity to reexamine how they access their collections. it draws these two traditional groups together with it specialists in order to collaborate on this new great challenge. in this paper, the authors offer a strategy for adapting a library system to traditional archival practice. t he librarian and the archivist . . . both collect, preserve, and make accessible materials for research; but significant differences exist in the way these materials are arranged, described, and used.”1 among the items usually collected by libraries are: published books and serials, and in more recent times, commercially available sound recordings, films, videos, and electronic resources of various types. archives, on the other hand, tend to collect original records of an organization, unique personal papers, as well as other effects of individuals and families. each type of institution, given its particular emphasis, has its own traditions and its own methods of dealing with its collections. most midto large-sized automated libraries in the united states and abroad use machine readable cataloging (marc) records to form the basis of their online catalogs. bibliographic records, including those in the marc format, generally represent an individually published item, or “information product,”2 and describe the physical characteristics of the item itself. the basic unit of archival description, however, is a much more complex entity than the basic unit of bibliographic description and often involves multiple hierarchical levels that may or may not extend down to the level of individual items. at portland state university (psu) the authors examined whether the capabilities of their present integrated library system could be expanded to capture the hierarchical structure of traditional archival finding aids. ■ background as early as 1841, the cataloging rules established by panizzi were geared toward locating individual published items. panizzi based his rules on the idea that any person looking for any particular book should be able to find it through the catalog.3 this tradition has continued over time up through current standards such as the anglo-american cataloguing rules and reaffirmed in marc, the standard for the representation and exchange of bibliographic information that has been widely used by libraries for over thirty years.4 archival description, on the other hand, is generally based on the fonds, that is, the entire collection of materials in any medium that were created, accumulated, and used by a particular person, family, or organization in the course of that creator’s activities and functions.5 thus, the basic unit of archival description, usually a finding aid, is a much more complex entity than the basic unit of bibliographic description, often involving multiple hierarchical levels of description that may or may not extend down to the level of individual items. before archival description begins, the archivist identifies related groups of materials and determines their proper arrangement. once the arrangement is determined, then the description of the materials reflects both their provenance and their original order.6 the first explicit statement of the levels of arrangement in an archival collection was by holmes and has since been elevated to the level of dogma in the archival community.7 a more recent statement in describing archives: a content standard (dacs) indicates that the actual levels of arrangement may differ for each collection. by custom, archivists have assigned names to some, but not all, levels of arrangement. the most commonly identified are collection, record group, series, file (or filing unit), and item. a large or complex body of material may have many more levels. the archivist must determine for practical reasons which groupings will be treated as a unit for purposes of description.8 rephrasing holmes, the five levels of arrangement can be defined as: 1. the collection level which holmes called the depository level—the breakdown of the depository’s complete holdings into a few major divisions based on the broadest common denominator 2. the record group level—the fonds or complete collection of the papers of a particular administrative division or branch of an organization or of a particular individual or family 3. the series level—the breakdown of the record group into natural series and the arrangement of each series with respect to the others 4. the filing unit level—the breakdown of each series into unit components, which are usually fairly obvious if the documents are kept in file folders 5. the document level—the level of individual items digital collection management through the library catalog michaela brenner, tom larsen, and claudia weston digital collection management

usually a finding aid that ideally presents an accurate representation of the items in an archival collection so that users can, as independently as possible, locate them.9 building on the print finding aid, the archival community has explored a number of mechanisms for disseminating information on the availability of items in their collections. in 1983, the usmarc format for archival and manuscript control (marc-amc) was released and subsequently sanctioned for use as one possible standard data structure and communication protocol in the saa descriptive standard archives, personal papers, and manuscripts (appm) and its successor, dacs.10 its adoption, however, has been somewhat controversial among archivists.11 the difficulty in capturing the hierarchical nature of collections through the marc format is one factor that has limited the use of marc by the archival community. while it is possible to encode this hierarchical description in marc using notes and linking fields, few archivists in practice have actually made use of these linking fields.12 thus, in archival cataloging, marc records have been used primarily for collection-level description, allowing users to search and discover only general information about archival collections in online catalogs while the finding aid has remained the primary tool for detailed data at all levels of description. in 1995, the encoded archival description (ead) emerged as a new standard for encoding descriptions of archival collections. the ead standard, like the marc standard, allows for the electronic storage and exchange of archival information; but unlike marc, it is based on the finding aid. ead is well suited for encoding the hierarchical relationships between the different parts of the collection and displaying them to the user, and it has become more widely adopted by the archival community. as outlined, the standards and systems chosen by an institution are dictated by the needs and traditions of that institution. the archival community relies heavily on finding aids and, with increasing frequency, on ead, their electronic extension; whereas the library community heavily relies on the online public access catalog (opac) and marc records. new trends capitalizing on the strengths of both traditions are evolving as libraries and archives seek ways to improve access to their archival and digital collections. ■ access to digital archival collections in libraries when searching the web for collections of information, one frequently encounters separate interfaces for traditional library, archival, and digital collections even though these collections may be owned, sponsored, hosted, or licensed by a single institution. descriptive records for traditional library materials reside in the opac and are constructed according to standard library practice, while finding aids for the archival and digital collections increasingly appear on specially designed web sites. this, of course, means that users searching the opac may miss relevant materials that are described only in the archival and digital documents database or web site. similarly, users searching the archival and digital documents database or web site may miss relevant materials that are described only in the opac. in other instances, libraries, such as the library of congress, selectively add records to their opacs for individual items in their archival and digital document collections. this incorporation allows users more complete access to items within the library’s collections. authority control and the assignment of descriptors further enhance access to the item-level records. to minimize processing costs, however, libraries frequently create brief descriptive records for items, thereby limiting their value to patrons.13 by creating descriptive records for the items only, libraries also obscure the hierarchical relationships among the items and the collections in which they reside. these relationships can provide the user with a useful context for the individual items and are an essential part of archival description. still other libraries, such as the university of washington, include collection-level marc records in the opac for their archival and digital document collections. these are searchable in the opac in the same way as bibliographic records for other materials. these collection-level records can then in turn be linked to finding aids that describe the collections more fully.14 collection-level records often are used in libraries where library resources may be insufficient for cataloging large collections of materials at the item level.15 the guidelines for collection-level records in appm and dacs, however, allow for additional fields that are not ordinarily used in library bibliographic records. these include such things as descriptions of the organization and arrangement of the collection, citations for published descriptions of the collection and links to the finding aid, and acknowledgment of the donors, as well as ample subject access to the collection. despite their potential for detail, collectionlevel records cannot provide the same degree of access to individual items as full item-level records. ■ an approach taken at portland state university library in many ways, archival and digital-document collections are continuing resources. a continuing resource is defined as “. . . a bibliographic resource that is issued over time digital collection management through the library catalog | brenner, larsen, and weston 67 with no predetermined conclusion. continuing resources include serials and ongoing integrating resources.”16 like published continuing resources, archival and digital collections generally are created over time with no predetermined conclusion. in fact, some archival collections continue to grow even after part of the collection has been accessioned by a library or archive. thus, even though many of the individual items in the collection might be properly treated as monographic (not unlike serial analytics), it would not be unreasonable to treat the entire collection as a continuing resource. with this in mind, the authors examined whether their electronic-resource management system could be adapted to accommodate evolving collections of digitized and born-digital material. more specifically, the present system was examined to determine whether its capabilities could be expanded to capture the hierarchical structure found in traditional archival finding aides. the electronic resource management system in use by psu library is innovative interfaces’ electronic resource management (erm) product. according to innovative interfaces inc.’s (iii) marketing literature, “[erm] effectively controls subscription and licensing information for licensed resources such as e-journals, abstracting and indexing (a&i) databases, and full-text databases.”17 to control and provide improved access to these resources, erm stores details about purchase orders, aggregators and publishers, subscription terms, licensing conditions, breadth of holdings, internal and external contact information, and other aspects of these resources that individual libraries consider relevant. for increased security and data integrity, multilevel permissions restrict viewing and editing of data to the appropriate level of staff or patron. the ability of erm to replicate the two-level hierarchical relationships between aggregators or publishers and the electronic and print resources they provide was of particular interest to the authors. through erm and iii’s batch record load capabilities, bibliographic and resource records can be loaded into the iii system using delimited source files such as those provided by serials solutions. resource records are the mechanisms used by iii to describe digital resources at a collection, subcollection, or title level, thereby enabling the capture of descriptive information not permitted by standard bibliographic records. iii uses holdings records to document serial holdings statements. according to the marc 21 formats for holdings data, a holdings statement is the “record of the location(s) and bibliographic units of a specific bibliographic item held at one or more locations.”18 iii holdings records may also contain a url for connecting to an electronic resource. in figure 1, for example, the resource record shows that psu library provides limited access to a number of journal titles through its springer journals online resource. as seen in figure 2, the display of a holdings record embedded in a bibliographic record provides more specific information on the availability of a title through the library’s collection. in this particular example, the information display reveals that print volumes are available for this title but that psu only has this title available as a part of the springer-verlag electronic collection accessible by clicking on the hotlink. more information on the springer collection can be discovered by clicking on the about resource button to retrieve the springer journals online resource record. this example, then, represents a two-level hierarchy where the resource springer journals online is analogous to an archival collection and abdominal imaging is analogous to an archival series. adaptation of erm for library-created digital collections was explored through work being done to fulfill the requirements of a grant received in 2005 by psu library. the goal of this grant was “to develop a digital library under the sponsorship of the portland state university library to serve as a central repository for the collection, accession, and dissemination of key planning documents and reports, maps, and other ephemeral materials that have high value for oregon citizens and for scholars around the world.”19 the overall collection is called the oregon sustainable community digital library (oscdl). in addition to having its own web site, it was decided to make this collection accessible through the psu library catalog so that patrons could find digitized original documents about the city of portland together with other library materials. bibliographic records would be added to the database with hyperlinks to the digitized original documents using existing staff and tools. these bibliographic marc records would be as complete as possible. initially, attention was focused on documents originating from four different sources: ernest bonner, a former portland city planner; the city of portland archives; metro (the regional government for the portland, oregon, metropolitan area); and trimet (the portland metropolitan public transportation system). along with the documents, metadata was received from various databases. these descriptions ranged from almost nothing to detailed archival descriptions. unlike the challenge of shifting titles and holdings with typical serials collections, the challenge of this project was to reflect the four hierarchical levels of psu library’s collection (figure 3). innovative’s system structure was manipulated in order to accomplish this. at the core of iii’s erm module are resource records (rr) created to reflect the peculiarities of a particular collection. linked to these resource records are holdings records (hr) containing hyperlinks to the actual digitized documents (doc h1 – doc h3) as well as to their respective bibliographic records (bib doc h1 – bib doc h3) containing additional information on the individual items within the collection (figure 4). 68 information technology and libraries | june 2006 first, resource records were manually created for three of the subcollections within the bonner collection. these subcollections contained documents reflecting the development of harbor drive, front street, and the park blocks. the fields defined for the resource records include the resource title; type (digitized documents) and format (pdf) of the resource; a hyperlink to the new oscdl web site; content and systems contact names; a brief description of the resource; and, most importantly, the resource id used to connect holding records for individual documents to the corresponding resource record. next, the batch-loading function in erm was used to create bibliographic and holding records and associate them with the resource records. taking advantage of tracking data produced during the digitization process (figure 5), spreadsheets were created for each collection reflecting the data assigned to each individual digitized document. the document title, the date the document was created, number of pages, and summaries were included. coordinates for the streets mentioned in the documents were also included. because erm uses issn numbers and titles as match points for record loads, ”issn” numbers were also manufactured for each document and included in the spreadsheet. these homemade numbers were distinguished by using pdx as a prefix followed by collection and document numbers or letters, for example, pdx0022090 or pdxhdcoll. fortunately, erm accepted these dummy issns (figure 6). from this data spreadsheet, the system-required comma delimited coverage load file (*.csv) was also created. for this file, the system only allows a limited number of fields, and is very particular about the right terms, including correct capitalization, for the header row. individual document titles, the made-up issn numbers, individual urls to the documents, and a collection-specific resource id (provider) that connects all the documents from a collection to their respective resource record were included. the resource id is the same for all documents in one collection (figure 7). in the first attempt, the system was set up to produce holdings and bibliographic records automatically, using the data from the spreadsheets. for the bibliographic records, a system-provided template was created that included some general subject headings, genre headings, an author field, and selected fixed fields, such as language, bibliographic level, and material type (figure 8). records for the harbor drive collection were loaded, and the system created brief bibliographic and holdings records and linked them to the harbor drive resource record. the records were globally updated to add the general material designator (gmd) “electronic resource” to the title as well as the phrase “digitized document” as a local “call number” to make these documents more visible in the browse screen of the online catalog (opac) (figure 9). the digitized documents now could be found in the library catalog by author, subject, or keyword. the brief bibliographic records (figure 10) allow the user to go either to the digitized document via url or to the resource record with more information on the resource itself and links to other items in the same collection. the resource record then provides links either to the new oscdl web site (via the <street name> oregon sustainable community digital library link at the bottom of the resource record), to the bibliographic description of the individual document, or to the digitized document (figure 11). however, the quality of the brief bibliographic records that had been batch generated through the system-provided template was not satisfactory (figure 8). it was decided that more document-specific data like summaries, number of pages, the dates the documents were created, geographical information, and documentlevel local subject headings should be included. these data were already available from the original spreadsheets. with limited time and staff resources, full bibliographic marc records were batch created using the spreadsheets, detailed templates adjusted slightly to each collection, microsoft mail merge, and finally, the marcedit program created by terry reese of oregon state university (http://oregonstate.edu/~reeset/marcedit/html/index.html). this gave maximum control over the data to be included and the way they would be included. it also eliminated the need to clean up the data following the record load (figure 12). subsequently, full bibliographic records were created for the subcollections harbor drive, front street, and park blocks, to connect them to the next higher level, the bonner collection (figure 3). these records were also contributed to worldcat. mimicking the process used at the document level, a resource record was created for the bonner collection and the holdings records for the three subcollections were connected with their corresponding bibliographic records (figure 13). resource records with their corresponding item-level records for trimet, the city archives, and metro followed. the final step was then to add the resource record and the bibliographic record for the whole oscdl collection (figure 14). since this last bibliographic record is not connected to a collection above it, there is only a hyperlink to the oscdl resource record (figure 15). more subcollections and their corresponding digital documents are continually being added to oscdl. structures in psu library’s opac are adjusted as these collections change. digital collection management through the library catalog | brenner, larsen, and weston 69 ■ conclusion according to salter, “digitizing, the current challenge that straddles the 20th and 21st centuries, has given archivists and librarians pause to reconsider access to their collections. the world of digitization is the catalyst for it people, librarians, and archivists to unify the way they do things.”20 in this paper, a strategy has been offered for adapting a library system to traditional archival practice. by making use of some of the capabilities of the module in psu library’s integrated library system that was originally designed for managing electronic resources, a method was developed for managing digital archival collections in a way that incorporates some of the features of a traditional finding aid. the contents of the various hierarchical levels of the collection are fully represented through the manipulation of the record structures available through psu’s system. this technique provides for enhanced access to the individual items of a collection by giving the context of the item within the collection. links between the hierarchical levels facilitate navigation between the levels. although the records created for traditional library systems are not as rich as those found in traditional finding aids, or in ead, their electronic equivalent; and the visual arrangements are not as intriguing as a wellplanned web site, the ability to show how items fit within the greater context of their respective collection(s) is a step toward reconciling traditional library and archival practices. enabling the library user to virtually browse through the overall resources offered by the library and then, if desired, through the various levels of a collection for relevant resources enhances the opportunities presented to the user for finding relevant information. references and notes 1. society of american archivists, “so you want to be an archivist: an overview of the archival profession,” 2004,

book reviews in the beginning ... was the command line by neal stephenson. new york: avon books, inc., 1999. 151p. $10 (isbn 0-38081593-1) neal stephenson is best known for his cyberfiction, including snow crash and most recently cryptonomicon. in the beginning . . . was tlze command line is a quite different kettle of fish. command line is a short book with a succinct message: the command line is a good thing, because the full power of the computer is only available to those who can access the command line and type in the magic commands that make things happen. stephenson learned this lesson the hard way, after first spending much time as a macintosh-devoted guihead. the revelation came when he lost a document he was editing on his powerbook, completely and without a trace, forever irretrievable. actually, i say the book has a succinct message, but it has many messages and many metaphors, all artfully constructed by a master of prose. stephenson constructs his arguments along multiple lines, providing a discursive tour through windows, macintosh, and unix history, offering personal history as well as his own take on the economics of the software industry. for example, he believes that microsoft would be better off as an applications company rather than carrying the millstone of a family of operating systems. as for apple, he suggests that they have been doing their best to destroy themselves for years, so far unsuccessfully (but give them time). the real meat of the book is whether, in fact, it is better to offer to people the flash of metaphor with the recognition that power and certain levels of choice are lost, as with graphical user interfaces exemplified by windows and the macintosh, or whether it is better to have at least some access to the command line interface, which ms/dos offered and members of the unix family (e.g., linux) afford. this is, in fact, both a silly and important question at the same time. silly because many people would wonder why anyone would want command line access to any software. silly because others might wonder why you couldn't have both. important, or at least apparently important, because we seem to have become, without much warning, a world wrapped in guis of one sort or another. important in the library automation world, because end-user tools are moving increasingly toward gui-based or web-based interfaces without textbased alternatives (except, perhaps, lynx or similar web browsers, which have their own problems). for much of the book, stephenson dances around the question, among others, of why not both gui and text-based interfaces, and finally finds the answer in the be operating system. my question is, why not as many interfaces as it takes, of whatever sort? to repeat the trite saw, there are two kinds of people in the world, those who divide the world into two kinds of people and those who don't. stephenson has a lot of fun trying to make the division in this case, then ultimately comes out from behind the posturing and admits that he believes in the availability of both worlds. there are many people who do, indeed, want hard things hidden from them, at least some of the time. when i am dealing with an automated teller machine, i don't want to have to use mechanical levers or pedals as i might have needed were atms invented in an earlier age, nor do i want to type in commands, although i am comfortable using a command line environment in my workplace. i just want to be prompted through a minimal number of steps to walk away with some cash from my checking account. the world is a complicated and challenging place to navigate. some people tom zillner, editor would like to be helped by other people in this navigation, although many have found that they would far rather deal with the dumbeddown interface of an atm machine than to interact with not-so-friendly, underpaid bank tellers. similarly, many people want to accomplish a particular task requiring the use of a computer and don't mind having the details hidden from them, no matter how much power knowing the details would provide. or, they want to do that at least some of the time. as an example in the library world, let's consider a nai:ve patron who enters the library desiring to perform a known-item search. such a user might be quite comfortable with an interface with a single type-in box and a set of clickable buttons labeled title, author and subject. or maybe just a single button "click to start search." although nai:ve users may consult library staff, who are most often more friendly than bank tellers, many people want to find their own materials. at the same time, more sophisticated users want more sophisticated capabilities and interfaces from the same catalogs. although vendors have gotten better at providing a couple of levels of complexity and corresponding user interfaces, why not go further? there aren't just two kinds of people. there are lots of kinds of people, with lots of kinds of information needs, representing lots of experience levels. why the restrictions at the user interface? in the history of microcomputing, stephenson points to the evolution of two major players, microsoft and apple, with linux coming on strong and be representing an interesting offshoot. i think the important insight implicit in what stephenson discusses is that much of the appearance and behavior of windows and the macintosh desktop are historically based artifacts. in order to maintain backward compatibility with existing applications, the windows and macintosh book reviews 103 reproduced with permission of the copyright owner. further reproduction prohibited without permission. operating systems have picked up a great deal of "cruft," computer code that allows multitasking and other improvements cobbled on to the fragile inner shell of ancient code required for compatibility with older applications. at the same time, stephenson invokes the familiar refrain that the user interfaces of both platforms are tied to a tired set of metaphors that attempt to mimic the real-world office (e.g., desktop, folder) but do not do so with any kind of useful fidelity. in the library world, i think a similar kind of lineage might be traced from command line interfaces to the current windowsand web-based front-ends. although many libraries and librarians have faced painful conversion processes over the years in moving through generations of automated systems, it might be interesting to see if there are still traces of underlying code that owe their existence to backward compatibility. where does stephenson turn in the face of the inelegance of the windows and macintosh worlds? he finds solace in the power and integrity of linux. it may take a long time to successfully install the operating system and get it to function with all of the hardware components of a particular computer configuration, but it has all that power, and all of those cool applications carefully constructed by people who care. bugs are fixed quickly. it's a community effort. that's all very appealing, particularly when compared to the appalling response (or lack of it) to windows or macintosh bugs. the problem is that so far most of us aren't equipped to deal with the steep curve required to install linux on personal computers, and the corporate or library environment usually isn't politically prepared for linux to be adopted as an institutionwide standard. so, while linux boxes are frequent choices for servers, they are not widespread personal pc choices. nor r.hould they be until easy installation tools are available. again, stephenson is ambivalent. on the one hand, he recognizes that there are many people who don't want the kind of power offered by being so close to the machine if it means becoming experts in arcane commands and codes. even though he wants the power and simplicity, and decries the limitations imposed by the gui, he recognizes that linux is not for everyone. he's right. most people use computers to get some work done (or to play). to the extent that the software gets in the way, it isn't operating properly. by that criterion, none of the three environments described are particularly useful in a desktop world. in spite of the fact that the old metaphors have been rightly criticized for years for their tiredness, there doesn't seem to be much movement beyond them, except in limited research operating environments and applications. similarly, it seems, in the library and information world, at least in most people's routine interactions with opacs and databases. yes, i am waffling, because i'm sure that someone could point out the "snarfle n 1 virtual reality interface to the lc catalog that affords a walkthrough browsing experience," but of course only six computer science researchers have actually experienced the snarfletm interface, and it requires a $25,000 workstation and $10,000 in virtual reality gear to work, plus it is s-1-o-w. pardon the sarcastic riff, but there is a lot of wonderful user interface work that is certainly not finding its way onto mainstream computer users' desktops, or to the library or information center. so what's the answer? criticism is fun, because critics don't necessarily have to provide a positive account to match their nay-saying function. if things are bleak in the world of the user interface, both on the average user desktop and on the library desk104 information technology and libraries i june 2000 top as well, what is to be done? for a taste of what is to come in the library world, take a look at mylibrary (http:/ /my.lib.ncsu.edu/), which allows profiling of user preferences and customization based on academic discipline. similarly, there are a number of web portals and other sites that allow customization for users (e.g., my yahoo, my excite, etc.). suppose that these first steps in customization are carried further, so that each user's unique profile generates a unique user interface experience across all databases he or she deals with in a session. the interface unification could be accomplished across heterogeneous databases in a couple of different ways. a simple initial step that many libraries already employ is to obtain databases from a single aggregator, so that a uniform interface is presented to the user. for example, oclc' s first search offers a single interface to a number of commercial databases. this type of solution is not possible for libraries that need access to a diverse array of databases not available through a single aggregator or vendor. of course, this situation can present patrons and staff with a bewildering array of interfaces and search methods. a more elaborate solution is to employ z39.50 to access the databases and build a single interface at the front end. there may be aggregators that already use this strategy with the databases they provide, but in the future perhaps there would be an incentive to offer unified interfaces with fine-grain customization possible by users. getting back to stephenson's more generalized view of the user interface, i think there are also opportunities here for more finegrained customization. stephenson points to the beos, which apparently allows both command-line and guibased interactions, as an example of what can be done when an operating system is constructed anew, from the bottom up, with no pre-existing reproduced with permission of the copyright owner. further reproduction prohibited without permission. audience to satisfy. at the same time, and in contrast, stephenson extols the power of open software development, which he believes is most apparent in operating systems, the production of which he describes as money-losing propositions. yet, linux is tremendously successful without, for the most part, commercial gain for developers. can this same model be applied to interface and other development in the library world? in this example, might not some group of librarian coders (or coder librarians) work together to put mylibrary together with z39.50 capabilities and customization of interfaces to produce a little slice of paradise for library patrons? promising moves are being made within the library community to get open source efforts off the ground. this could be one of many especially useful and fruitful projects to come out of open software development for libraries. although his book is ostensibly about a few issues that elicit yawns from most of the world, stephenson is really using in the beginning . . . was the command line to look at a much bigger picture than simply the command line versus the gui at its microscopic level. stephenson looks at the cloaking, obfuscation or replacement of underlying text by images and multimedia as contributing to the decline of civilization. that seems like a radical claim, but at heart it is the one that stephenson makes in his discussion of the disney-ification of the world-that visual metaphors and explanations oversimplify and obscure the truth. in fact, stephenson goes further, discussing this trend toward anti-word as our attempt at an antidote for the kind of intellectualism that resulted in a lot of death, pain, and suffering for people in the twentieth century. he, as a person who lives by words and loves the intellectual life, thinks we've gone too far, reaching a state of cultural relativism where there is neither good nor bad remammg. this discussion includes my favorite quote of the book: the problem is that once you have done away with the ability to make judgments as to right and wrong, true and false, etc., there's no real culture left. all that remains is clog dancing and macrame. the ability to make judgments, to believe things, is the entire point of having a culture. i think this is why guys with machine guns sometimes pop up in places like luxor and begin pumping bullets into westerners .... when their sons come home wearing chicago bulls caps with the bills turned sidewavs, the dads go out of their minds. (p. 56) it's a pretty startling move to try to connect up the decline in use of the command line to an anti-intellectualism following world war ii that resulted in cultural relativism. i think it actually has some merit, although in the case of visual interfaces versus the command line the ethical import is minimal, i.e., i don't believe my decision to accomplish certain tasks using visual metaphors contributes to the decline of civilization, and i think the fact that i like to work on other tasks utilizing a command line won't serve to save our written culture. it's too much of a stretch. i think that something stephenson misses in his discussion of the replacement of the written word by visual images is that there is still a creative force and judgment involved in the creation of the images. there is still script writing. isn't this, after all, what a writer does in any case, creating images, metaphorically, through his or her work? certainly, we are moving through a perilous time, when the world really is changing from a reliance on the written word to more dependence on the visual. there will be many things lost in this transition. plato had some major, wellfounded doubts about the transition from greece's oral cultural tradition to a written one. the change happened anyway. civilization has been declining for a long time. my fearless prediction is that it will continue to decline for a long time. i think stephenson has done a masterful job of writing a brief glimpse of the overall picture that represents the state of culture and intellectual life in the world today, and has also made some important points about the economics and character of the world of software and operating environments. his writing skills make this fairly short book a pleasurable read and a worthwhile one. as i did, i think you might find this long essay a useful starting point for thoughts about issues large and small.-tom zillner, wils the cathedral & the • bazaar: musings on linux and open source by an accidental revolutionary by eric s. raymond, sebastopol, calif.: o'reilly, 1999. 288p. $19.95 (isbn 156592-724-9) this short essay examines, in the guise of a book review, the concept of a "gift culture" and how it may or may not be related to librarianship. as a result of this examination, and with a few qualifications, i believe my judgements about open source software and librarianship are true: open source software development and librarianship have a number of similarities-both are examples of gift cultures. i have recently read a book about open source software development by eric raymond. the cathedral & the bazaar describes the environment of free software and tries to explain why some programmers are willing to give away the products of their labors. it describes the "hacker milieu" as a "gift culture": book reviews 105 reproduced with permission of the copyright owner. further reproduction prohibited without permission. gift cultures are adaptations not to scarcity but to abundance. they arise in populations that do not have significant material scarcity problems with survival goods. we can observe gift cultures in action among aboriginal cultures living in ecozones with mild climates and abundant food. we can also observe them in certain strata of our own society, especially in show business and among the very wealthy. 1 raymond alludes to the definition of "gift cultures," but not enough to satisfy my curiosity. being the good librarian, i was off to the reference department for more specific answers. more often than not, i found information about "gift exchange" and "gift economies" as opposed to "gift cultures." (yes, i did look on the internet but found little.) probably one of the earliest and more comprehensive studies of gift exchange was written by marcell mauss. 2 in his analysis he says gifts, with their three obligations of giving, receiving, and repaying, are in aspects of almost all societies. the process of gift giving strengthens cooperation, competitiveness, and antagonism. it reveals itself in religious, legal, moral, economic, aesthetic, morphological, and mythological aspects of life.3 as gregory states, for the industrial capitalist economies, gifts are nothing but presents or things given, and "that is all that needs to be said on the matter." ironically for economists, gifts have value and consequently have implications for commodity exchange. 4 he goes on to review studies about gift giving from an anthropological view, studies focusing on tribal communities of various american indians, cultures from new guinea and melanesia, and even ancient roman, hindu, and germanic societies: the key to understanding gift giving is apprehension of the fact that things in tribal economics are produced by nonalienated labor. this creates a special bond between a producer and his/her product, a bond that is broken in a capitalistic societv based on alienated wage-labor. 5 ingold, in "introduction to social life," echoes many of the things summarized by gregory when he states that industrialization is concerned exclusively with the dynamics of commodity production. clearly in non-industrial societies, where these conditions do not obtain, the significance of work will be very different. for one thing, people retain control over their own capacity to work and over other productive means, and their activities are carried on in the context of their relationships with kin and community. indeed their work may have the strengthening or regeneration of these relationships as its principle objective. 6 in short, the exchange of gifts forges relationships between partners and emphasizes qualitative as opposed to quantitative terms. the producer of the product (or service) takes a personal interest in production, and when the product is given away as a gift it is difficult to quantify the value of the item. therefore, along with the product or service, less tangible elements-such as obligations, promises, respect, and interpersonal relationships-are exchanged. as i read raymond and others i continually saw similarities between librarianship and gift cultures, and therefore similarities between librarianship and open source software development. while the summaries outlined above do not necessarily mention the "abundance" alluded to by raymond, the existence of abundance is more than mere speculation. potlatch, "a ceremonial feast of the american indians of the northwest coast marked by the host's lavish distribution of gifts or sometimes destruction of property to demonstrate wealth and generosity with the 106 information technology and libraries i june 2000 expectation of eventual reciprocation," is an excellent example.? libraries have an abundance of data and information. (i won't go into whether or not they have an abundance of knowledge or wisdom of the ages. that is another essay.) libraries do not exchange this data and information for money; you don't have to have your credit card ready as you leave the door. libraries don't accept checks. instead the exchange is much less tangible. first of all, based on my experience, most librarians simply take pride in their ability to collect, organize, and disseminate data and information in an effective manner. they are curious. they enjoy learning things for learning's sake. it is a sort of platonic end in itself. librarians, generally speaking, just like what they do and they certainly aren't in it for the money. you won't get rich by becoming a librarian. information is not free. it requires time and energy to create, collect, and share, but when an information exchange does take place, it is usually intangible, not monetary, in nature. information is intangible. it is difficult to assign it a monetary value, especially in a digital environment where it can be duplicated effortlessly: an exchange process is a process whereby two or more individuals (or groups) exchange goods or services for items of value. in library land, one of these individuals is almost always a librarian. the other individuals include tax payers, students, faculty, or in the case of special libraries, fellow employees. the items of value are information and information services exchanged for a perception of worth-a rating valuing the services rendered. this perception of worth, a highly intangible and difficult thing to measure, is something the user of library services "pays," not to libraries and librarians, but to administrators and decision-makers. ultimately, these payments reproduced with permission of the copyright owner. further reproduction prohibited without permission. manifest themselves as tax dollars or other administrative support. as the perception of worth decreases so do tax dollars and support. 8 therefore, when information exchanges take place in libraries, librarians hope their clientele will support the goals of the library to administrators when issues of funding arise. librarians believe that "free" information ("think free speech, not free beer") will improve society. it will allow people to grow spiritually and intellectually. it will improve humankind's situation in the world. libraries are only perceived as beneficial when they give away this data and information. that is their purpose, and they, generally speaking, do this without regard to fees or tangible exchanges. in many ways i believe open source software development, as articulated by raymond, is very similar to the principles of librarianship. first and foremost they are similar in the idea of sharing information. both camps put a premium on open access. both camps are gift cultures and gain reputation by the amount of "stuff" they give away. what people do with the information, whether it be source code or journal articles, is up to them. both camps hope the shared information will be used to improve our place in the world. just as jefferson's informed public is necessary for democracy, open source software is necessary for the improvement of computer applications. second, human interactions are a necessary part of the mixture in both librarianship and open source development. open source development requires people skills by source code maintainers. it requires an understanding of the problem the computer application is intended to solve, since the maintainer must be able to "patch" the software, both to add functionality and to repair bugs. this, in turn, requires interactions both with other developers and with users who request repairs or enhancements. similarly, librarians understand that information-seeking behavior is a human process. while databases and many "digital libraries" house information, these collections are really "data stores" and are only manifested as information after the assignment of value is given to the data and interrelations between data are created. third, it has been stated that open source development will remove the necessity for programmers. yet raymond posits that no such thing will happen. if anything, there will be an increased need for programmers. similarly, many librarians feared the advent of the web because they believed their jobs would be in jeopardy. ironically, librarianship is flowering under new rubrics such as information architects and knowledge managers. it has also been brought to my attention by kevin clarke (kevin_clarke@unc.edu) that both institutions use peer-review: your cultural take (gift culture) on "open source" is interesting. i've been mostly thinking in material terms but you are right, i think, in your assessment. one thing you didn't mention is that, like academic librarians, open source folks participate in a peer-review type process. index to advertisers all of this is happening because of an information economy. it sure is an exciting time to be a librarian, especially a librarian who can build relational databases and program on a unix computer.

box for 2 column layout based on data collected as part of the 2006 public libraries and the internet study, the authors assess the degree to which public libraries provide sufficient and quality bandwidth to support the library’s networked services and resources. the topic is complex due to the arbitrary assignment of a number of kilobytes per second (kbps) used to define bandwidth. such arbitrary definitions to describe bandwidth sufficiency and quality are not useful. public libraries are indeed connected to the internet and do provide public-access services and resources. it is, however, time to move beyond connectivity type and speed questions and consider issues of bandwidth sufficiency, quality, and the range of networked services that should be available to the public from public libraries. a secondary, but important issue is the extent to which libraries, particularly in rural areas, have access to broadband telecommunications services. t he biennial public libraries and the internet studies, conducted since 1994, describe public library involve­ ment with and use of the internet.1 over the years, the studies showed the growth of public­access comput­ ing (pac) and internet access provided by public libraries to the communities they serve. internet connectivity rose from 20.9 percent to essentially 100 percent in less than ten years; the average number of public access computers per library increased from an average of two to nearly eleven; and bandwidth rose to the point where 63 percent of public libraries have connection speeds of greater than 769kbps (kilobytes per second) in 2006. this dramatic growth, replete with related information technology challenges, occurred in an environment of challenges—among them budgetary and staffing—that public libraries face in main­ taining traditional services as well as networked services. one challenge is the question of bandwidth suf­ ficiency and quality. the question is complex because typically an arbitrary number describes the number of kbps used to define “broadband.” as will be seen in this paper, such arbitrary definitions to describe band­ width sufficiency are generally not useful. the federal communications commission (fcc), for example, uses the term “high speed” for connections of 200kbps in at least one direction.2 there are three problematic issues with this definition: 1. it specifies unidirectional bandwidth, meaning that a 200kbps download, but a much slower upload (e.g., 56kbps) would fit this definition; 2. regardless of direction, bandwidth of 200kbps is neither high speed nor does it allow for a range of internet­based applications and services. this inad­ equacy will increase significantly as internet­based applications continue to demand more bandwidth to operate properly. 3. the definition is in the context of broadband to the single user or household, and does not take into consideration the demands of a high­use multiple­ workstation public­access context. in addition to connectivity speed, there are many ques­ tions related to public library pac and internet access that can affect bandwidth sufficiency—from budget and sus­ tainability, staffing and support, to services public librar­ ies offer through their technology infrastructure, and the impacts of connectivity and pac on the communities that libraries serve. one key question, however, is what is quality pac and internet bandwidth for public libraries? and, in attempting to answer that question, what are measures and benchmarks of quality internet access? this paper provides data from the 2006 public libraries and the internet study to foster discussion and debate around determining quality pac and internet access.3 bandwidth and connectivity data at the library outlet or branch level are presented in this article. the band­ width measures are not systemwide but rather at the point of service delivery in the branch. ■ the bandwidth issue there are a number of factors that affect the sufficiency and quality of bandwidth in a pac and internet service context. examples of factors that influence actual speed include: ■ number of workstations (public­access and staff) that simultaneously access the internet; ■ provision of wireless access that shares the same con­ nection; ■ ultimate connectivity path—that is, a direct connec­ tion to the internet that is truly direct, or one that goes through regional or other local hops (that may have aggregated traffic from other libraries or orga­ nizations) out to the

(databases, videoconfer­ encing, interactive/real­time services) to which the library is linked; ■ if networked, the speed of the network on which the public­access workstations reside; and ■ general application resource needs, protocol priority, and other general factors. thus, it is difficult to precisely answer “how much bandwidth is enough” within an evolving and dynamic context of public access, use, and infrastructure. putting public­access internet use into a more typi­ cal application­and­use scenario, however, may provide some indication of adequate bandwidth. for example: ■ a typical three­minute digital song is 3mb; ■ a typical digital photo is about 2mb; and ■ a typical powerpoint presentation is about 10mb. if one person in a public library were to e­mail a powerpoint presentation at the same time that another person downloaded multiple songs, and another was exchanging multiple pictures, even a library with a t1 line (1.5mbps—megabytes per second) would experience a temporary network slowdown during these operations. this does not take into account many other new high­ bandwidth­consuming applications such as cnn stream­ ing­video channel; uploading and accessing content to a wiki, blog, or youtube.com; or streaming content such as cbs’s webcasting the 2006 ncaa basketball tournament. an increasingly used technology in various settings is two­way internet­based video conferencing. with an installed t1 line, a library could support two 512kbps or three 384kbps videoconferences, depending on the amount of simultaneous traffic on the network—which, in a public access context, would be heavy. indeed, the 2006 public libraries and the internet study indicated a near continuous use of public­access workstations by patrons (only 14.6 percent of public libraries indicated that they always had a sufficient number of workstations available for patron use). public libraries increasingly serve as access points to e­government services and resources, e.g., social services, disaster relief, health care.4 these services can require the simple completion of a web­based form (low­bandwidth consumption) to more interactive services (high­band­ width consumption). and, as access points to continuing education and online degree programs, public libraries need to offer adequate broadband to enable users to access services and resources that increasingly can depend on streaming technologies that consume greater bandwidth. ■ bandwidth and pac in public libraries today as table 1 demonstrates, public libraries continue to increase their bandwidth, with 63.3 percent of public libraries reporting connection speeds of 769kbps or greater. this compares to 47.7 percent of public libraries reporting connection speeds of greater than 769kbps in 2004. there are disparities between rural and urban pub­ lic libraries, with rural libraries reporting substantially fewer instances of connection speeds of greater than 1.5mbps in 2006. on the one hand, the increase in con­ nectivity speeds between 2004 and 2006 is a positive step. on the other, 16.1 percent of public libraries report that their connection speeds are insufficient to meet patron demands all of the time, and 29.4 percent indicate that their connection speeds are insufficient to meet patron demands some of the time. thus, nearly half of public libraries indicate that their connection speeds are insuf­ ficient to meet patron demands some or all of the time. in terms of public access computers, the average number of workstations that public libraries provide is 10.7 (table 2). urban libraries have an average of 17.1 workstations, as compared to rural libraries, which report an average of 7.1 workstations. a closer look at bandwidth and pac for the next sections, the data offer two key views for analysis purposes: (1) workstations—divided into libraries with ten or fewer public­access workstations and libraries with more than ten public­access worksta­ tions (given that the average number of public­access workstations in libraries is roughly ten); and (2) band­ width—divided into libraries with 769kbps or less and libraries with greater than 769kbps (an arbitrary indicator of broadband for a public library context). in looking across bandwidth and public­access work­ stations (table 3), overall 31.8 percent of public libraries have connection speeds of less than 769kbps while 63.3 percent have connection speeds of greater than 769kbps. a majority of public libraries—68.5 percent—have ten or fewer workstations, while 30.9 percent have more than ten workstations. in general, rural libraries have fewer workstations and lower bandwidth as compared to sub­ urban and urban libraries. indeed, 75.2 percent of urban 16 information technology and libraries | march 200716 information technology and libraries | march 2007 libraries with fewer than ten workstations have connec­ tion speeds of greater than 769kbps, as compared to 45.2 percent of rural libraries. when examining pac capacity, it is clear that public libraries have capacity issues at least some of the time in a typical day (tables 4 through 6). only 14.6 percent of public libraries report that they have sufficient numbers of workstations to meet patron demands at all times (table 6), while nearly as many, 13.7 percent, report that they consistently are unable to meet patron demands for public­access workstations (table 4). a full 71.7 percent indicate that they are unable to meet patron demands during certain times in a typical day (see table 5). in other words, 85.4 percent of public libraries report that they are unable to meet patron demand for public­access workstations some or all of the time during a typical day—regardless of number of workstations available and type of library. the disparities between rural and urban libraries are notable. in general, urban libraries report more difficulty in meeting patron demands for public­access workstations. of urban public libraries, 27.8 percent report that they consistently have difficulty in meeting patron demand for workstations, as compared to 11.0 percent of suburban and 10.6 percent of rural public libraries (table 4). by contrast, 6.6 percent of urban libraries report sufficient workstations to meet patron demand all the time as compared to 18.9 percent of rural libraries (table 6). when reviewing the adequacy of speed of connectiv­ ity data by the number of workstations, bandwidth, and metropolitan status, a more robust and descriptive pic­ table 1. public

ies indicate that their connection speeds are adequate to meet demand, some parsing of this figure reveals more variation (tables 7 through 10): ■ libraries with connection speeds of 769kpbs or less are more likely to report that their connection speeds are insufficient to meet patron demand at all times, with 24.0 percent of rural libraries, 25.8 percent of suburban libraries, and 25.4 percent of urban libraries so reporting (table 7). ■ libraries with connection speeds of 769kpbs or less are more likely to report that their connection speeds are insufficient to meet patron demand at some times, with 35.0 percent of rural libraries, 38.1 per­ cent of suburban libraries, and 53.4 percent of urban libraries so reporting (table 8). ■ libraries with connection speeds of greater than 769kbps also report bandwidth­sufficiency issues, with 12.0 percent of rural libraries, 10.5 percent of suburban libraries so reporting; and 14.0 percent of urban librar­ ies indicating that their connection speeds are insuf­ ficient all of the time (table 7); 20.3 percent of rural libraries, 29.5 percent of suburban libraries, and 30.0 percent of urban libraries indicating that their connec­ tion speeds are insufficient some of the time (table 8). ■ libraries that have ten or fewer workstations tend to rate their bandwidth as more sufficient at either 769kbps or less or greater than 769kbps (tables 7, 8, and 10). thus, in looking at the data, it is clear that libraries with fewer workstations indicate that their connection speeds are more sufficient to meet patron demand. table

discussion and selected issues the data presented point to a number of issues related to the current state of public library pac and internet­access adequacy in terms of available public access computers and bandwidth. the data also provide a foundation upon which to discuss the nature of quality and sufficient pac and internet access in a public library environment. while public libraries indicate increased ability to meet patron bandwidth demand when providing fewer publicly avail­ able workstations, public libraries indicate that they have difficulty in meeting patron demand for public access computers. growth of wireless connections in 2004, 17.9 percent of public library outlets offered wire­ less access, and a further 21.0 percent planned to make it available. outlets in urban and high­poverty areas were most likely to have wireless access. the majority of librar­ ies (61.2 percent), however, neither had wireless access nor had plans to implement it in 2004. as table 11 demon­ strates, the number of public library outlets offering wire­ less access has roughly doubled from 17.9 percent to 36.7 percent in two years. furthermore, 23.1 percent of outlets that do not currently have it plan to add wireless access in the next year. thus, if libraries follow through with their plans to add wireless access, 61.0 percent of public library outlets in the united states will have it by 2007. the implications of the rapid growth of the public library’s provision of wireless connectivity (as shown in table 11) on bandwidth requirements are significant. either libraries added wireless capabilities through their current overall bandwidth, or they obtained additional bandwidth to support the increased demand created by the service. if the former, then wireless access created an even greater burden on an already problematic band­ width capacity and may have actually reduced the overall quality of connectivity in the library. if the latter, libraries then had to shoulder the burden of increased expendi­ tures for bandwidth. either scenario required additional technology infrastructure, support, and expenditures. sufficient and quality connections the notion of sufficient and quality public library con­ nection to the internet is a moving target and depends on a range of factors and local conditions. for purposes of discussion in this paper, the authors used 769kbps to differentiate “slower” from “faster” connectivity. if, how­ ever, 1.5mbps or greater had been used to define faster connectivity speeds, then only 28.9 percent of public libraries would meet the criterion of “faster” connectiv­ ity (see table 1). and in fact, simply because 28.9 percent of public libraries report connection speeds of 1.5mbps or faster does not also mean that they have sufficient or quality bandwidth to meet the computing needs of their users, their staff, their vendors, and their service provid­ ers. some public libraries may need 10mbps to meet the pac needs of their users as well as the internal staff and management computing needs. the library community needs to become more edu­ cated and knowledgeable about what constitutes sufficient and quality connectivity in their library for the communi­ ties that they serve. a first step is to understand clearly the nature and type of the connectivity of the library. the next step is to conduct an internal audit that minimally: ■ identifies the range of networked services the library provides both to users as well as for the operation of the library; ■ identifies the typical bandwidth consumption of these services; ■ determines the demands of users on the bandwidth in terms of services they use; ■ determines peak bandwidth­usage times; ■ identifies the impact of high­consumption networked services used at these peak­usage times; ■ anticipates bandwidth demands of newer services and resources that users will want to access through the library’s infrastructure—myspace.com, youtube. com—regardless of whether or not the library is the direct provider of such services; and ■ determines what broadband services are available to the library, the costs of these services, and the “fit” of these services to the needs of the library. based on this and related information from such an audit, library administration can better determine the degree to which the bandwidth is sufficient in speed and quality. ■ planning for sufficient and quality bandwidth knowing the current condition of existing bandwidth in the library is not the same as successful technology plan­ ning and management to ensure that the library has, in fact, bandwidth that is sufficient in speed and quality. once an audit such as has been suggested is completed, careful planning for bandwidth deployment in the library is essential. it appears, however, that currently much of the management and planning for networked services is based first on what bandwidth is available as opposed to the bandwidth that is needed to provide the necessary services and resources in a networked environment. this stance puts public libraries in a reactive condition rather than a proactive condition regarding provision of net­ worked services. 20 information technology and libraries | march 200720 information technology and libraries | march 2007 most public library planning approaches stress the importance of conducting some type of needs assessment as a precursor to any type of planning.5 further, technology plans should include such things as goals, objectives, ser­ vices provision, and evaluation as they relate to bandwidth and the appropriate bandwidth needed. recent library technology planning guides, however, give little attention to the management, planning, and evaluation of band­ width as it relates to provision of networked services. it must be noted that some public libraries may be prevented from accessing higher bandwidth due to high cost, lack of availability of bandwidth alternatives, or other local factors that determine access to advanced telecommunications in their areas. in such circumstances, the audit may serve to inform the public service/utilities commissions, fcc, and others of the need for deploy­ ment of advanced telecommunications services in these areas. ■ bandwidth planning in a community context the audit and planning processes that have been described are critical activities for libraries. it is essential, however, for these processes to occur in the larger community con­ text. investments in technology infrastructure are increas­ ingly a community­wide resource that services multiple functions—emergency services, community access, local government agencies, to name a few. it is in this larger context that library pac and internet access occurs. moreover, there is a convergence of technology and service needs. for example, public libraries increasingly serve as agents of e­government and disaster­relief providers.6 first responders rely on the library’s infrastructure when theirs is destroyed, as hurricane katrina and other storms demonstrated. local, state, and federal government agen­ cies rely on broadband and pac and internet access (wired or wireless) to deliver e­government services. thus, at their core, libraries, emergency services, gov­ ernment agencies, and others have similar needs. pooling resources, planning jointly, and looking across needs may yield economies of scale, better service, and a more robust community technology infrastructure. emergency providers need access to reliable broadband and commu­ nications technologies in general, and in emergency situ­ ations in particular. libraries need access to high­quality broadband and pac technologies. both need access to wireless technologies. as broadcast networks relinquish ownership of the 700 mhz frequency used for analog television in february 2009, and this frequency is distributed to municipali­ ties for emergency services, now is an excellent time for libraries to engage in community technology planning for e­government, disaster planning and relief efforts, and pac and internet services. by working with the larger community to build a technology infrastructure, the library and the entire community benefit. ■ availability to high-speed connectivity one key consideration not known at this time is the extent to which public libraries—particularly those in rural areas—even have access to high­speed connec­ tions. many rural communities are served not by the large telecommunications carriers, but rather by small, privately owned­and­run local exchange carriers. iowa and wisconsin, for example, are each served by more than eighty exchange carriers. as such, public libraries are limited in capacity and services to what these exchange table 11. public-access wireless internet connectivity availability in public library outlets by metropolitan status and poverty metropolitan status

21assessing sufficiency and quality of bandwidth for public libraries | bertot and mcclure 21 carriers offer and make available. thus, in some areas, dsl service may be the only form of high­speed connec­ tivity available to libraries. and, as suggested earlier, dsl may or may not be considered high speed given the needs of the library and the demands of its users. communities that lack high­quality broadband ser­ vices by telecommunications carriers may want to con­ sider building a municipal wireless network that meets the community’s broadband needs for emergency, disas­ ter, and public­access settings. as a community engages in community­wide technology planning, it may become evident that local telecommunications carriers do not meet the broadband needs of the community. such com­ munities may need to build their own networks, based on identified technology­plan needs. ■ knowledge of networked services connectivity needs patrons may not attempt to use high­bandwidth services at the public library because they know from previous visits that the library cannot provide acceptable connec­ tivity speeds to access that service—thus, they quit trying to access that service, limiting the usefulness of the pub­ lic library. in addition, librarians may have inadequate knowledge or information to determine when bandwidth is or is not sufficient to meet the demands of their users. indeed, the survey and site visits revealed that some librarians did not know the connection speeds that linked their library to the internet. consequently, libraries are in a dilemma: increase both the number of workstations and the bandwidth to meet demand; or provide less service in order to operate within the constraints of current connectivity infrastruc­ ture. and yet, roughly 45 percent of public libraries indi­ cate that they have no plans to add workstations within the next two years; the average number of workstations has been around ten for the last three surveys (2002, 2004, and 2006); and 80 percent of public libraries indicate that space limitations affect their ability to add workstations.7 hence, for many libraries, adding workstations is not an option. ■ missing the mark? the networked environment is such that there are multi­ ple uses of bandwidth within the same library—for exam­ ple, public internet access, staff access, wireless access, integrated library system access. we are now in the web 2.0 environment, which is an interactive web that allows for content uploading by users (e.g., blogs, mytube.com, myspace.com, gaming). streaming content, not text, is increasingly the norm. there are portable devices that allow for text, video, and voice messaging. increasingly, users desire and prefer wireless services. this is a new environment in which libraries provide public access to networked services and resources. it is an enabling environment that puts users fully in the content seat—from creation to design to organization to access to consumption. and users have choices, of which the public library is only one, regarding the information they choose to access. it is an environment of competition, advanced applications, bandwidth intensity, and high­quality com­ puters necessary to access the graphically intense content. the impacts of this new and substantially more com­ plex environment on libraries are potentially significant. as user expectations rise, combined with the provision of high­quality services by other providers, libraries are in a competitive and service­ and resource­rich informa­ tion environment. providing “bare minimum” pac and internet access can have two detrimental effects in that they: (1) relegate libraries to places of last resort, and (2) further digitally divide those who only have public­access computers and internet access through their public librar­ ies. it is critical, therefore, for libraries to chart a high­end course regarding pac and internet access, and not access that is merely perceived to be acceptable by the librarians. ■ additional research the context in which issues regarding quality pac and sufficient connectivity speeds to internet access reside is complex and rapidly changing. research questions to explore include: ■ is it possible to define quality pac and internet access in a public library context? ■ if so, what are the attributes included in the defini­ tion? ■ can these attributes be operationalized and mea­ sured? ■ assuming measurable results, what strategies can the library, policy, research, and other interested communities employ to impact public library move­ ment toward quality pac and internet access? ■ should there be standards for sufficient connectivity and quality pac in public libraries? ■ how can public librarians be better informed regard­ ing the planning and deployment of sufficient and quality bandwidth? ■ what is the role of federal and state governments in supporting adequate bandwidth deployment for public libraries?8 ■ to what extent is broadband deployment and avail­ ability truly universal as per the universal service 22 information technology and libraries | march 200722 information technology and libraries | march 2007 (section 254) of the telecommunications act of 1996 (p.l. 104­104)? these questions are a beginning point to a larger set of activities that need to occur in the research, practitioner, and policy­making communities. ■ obtaining sufficient and quality public-library bandwidth arbitrary connectivity speed targets, e.g., 200kbps or 769kbps, do not in and of themselves ensure quality pac and sufficient connectivity speeds. public libraries are indeed connected to the internet and do provide public­ access services and resources. it is time to move beyond connectivity­type and ­speed questions and consider issues of bandwidth sufficiency, quality, and the range of networked services that should be available to the public from public libraries. given the widespread connectivity now provided from most public libraries, there continue to be increased demands for more and better networked services. these demands come from governments that expect public libraries to support a range of e­government services, from residents who want to use free wireless connectivity from the public library, to patrons who need to download music or view streaming videos (to name but a few). simply providing more or better connectivity will not, in and of itself, address all of these diverse service needs. increasingly, pac support will require additional public librarian knowledge, resources, and services. sufficient and quality bandwidth is a key component of those services. the degree to which public libraries can provide such enhanced networked services (requiring exceptionally high bandwidth that is both sufficient and of high quality) is unclear. mounting a significant effort now to better understand existing bandwidth use and plan for future needs and requirements in individual public libraries is essential. in today’s networked envi­ ronment, libraries must stay competitive in the provision of networked services. such will require sufficient and high­quality connectivity and bandwidth. ■ acknowledgements the authors gratefully acknowledge the support of the bill & melinda gates foundation and the american library

user experience, demographics, academic interests in vr, and methods of discovery. currently our institution offers one htc vive vr system that can be reserved and used by patrons within the library, but we would like to expand the service to meet the interests and needs of our patrons. we found use among all measured demographics and sufficient patron interest for us to justify expansion of our current services. the data resulting from this survey and the subsequent focus groups can be used to inform other academic libraries exploring or developing similar vr services. introduction virtual reality (vr) is commonly defined as an experience in which a user remains physically within their real world while entering a virtual world (comprising three-dimensional objects) using a headset with a computer or a mobile device.1 vr is part of a spectrum of related technologies ranging from mostly real experiences to completely virtual experiences, such as augmented reality, augmented virtuality, and mixed reality. 2 extended reality (xr) is a term often used when describing these technologies as a whole. many different xr devices and services are available in academic libraries. the most popular xr devices used in libraries are the htc vive, the oculus rift by facebook, and google cardboard.3 other common xr devices include gearvr by samsung and playstation virtual reality by sony.4 the htc vive and oculus rift are technologies that provide an immersive virtual-reality experience. google cardboard provides both non-immersive virtual reality and augmented reality experiences, while mixed reality is provided through various technologies such as microsoft’s hololens and mixed-reality headsets from hp, acer, and magic leap. in addition, many academic libraries are using augmented reality apps that can be downloaded on patrons’ personal mobile devices.5 academic libraries are starting to offer various xr services to increase engagement with patrons and teach information literacy.6 despite the increase in xr service offerings, there is little consistency in the devices used or in how these services are developed at academic libraries , and there is substantial variation in the types of services offered. for example, some libraries make vr headsets available for in-house activities, such as storytelling, virtual travel, virtual gaming, and the development of new skills.7 other libraries, notably ryerson university library and archives in toronto, let students and faculty borrow their oculus rift headsets for two or three days at a time.8 some university libraries lend out headsets or 360-degree cameras or provide a virtualmailto:megan@byu.edu mailto:michael_goates@byu.edu mailto:jed_johnston@byu.edu information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 2 reality space for students to develop content.9 the university of utah library offers an open-door, drop-in vr workshop once a week.10 claude moore health sciences library at the university of virginia implemented a project that educated its students and staff on the uses of vr in the health field through a combination of large-group demonstrations, one-on-one consultations, and workshops.11 the xr field is developing quickly, and xr services have the potential to benefit students academically. some universities are already offering classes on vr platforms.12 this is particularly true in fields that are high risk or potentially discomforting. for example, students in medical fields benefit by practicing virtually before attempting surgery on a human body.13 in addition to potential surgical benefits, the university of new england has been utilizing xr technology to teach empathy to its medical and other health profession students by putting the learner in the place of their patients.14 other examples of xr usage in the health fields include a recent attempt to introduce vr in anatomic pathology education and the use of virtual operating rooms to train nurses and educate the public. 15 one recent study measured the effectiveness of using vr platforms in engineering education and found a drastic improvement in student performance.16 many educational institutions outside of the university setting have also started exploring how xr could be used to enhance students’ educational experience. this technology has already progressed from being considered a novelty to being an established tool to engage learners.17 one of the perceived benefits of xr use in public libraries by both library patrons and staff is the ability of xr technology to inspire curiosity and a desire to learn.18 in some school programs, students are able to advance their learning through xr apps that allow them not only to absorb information but also to experience what they are learning through hands-on activities and full immersion without danger (e.g., hazardous science experiments) or high cost (e.g., traveling to another country).19 xr has the potential to increase the overall engagement of students, which, according to carnini, kuh, and klein’s 2006 study, is correlated to how well students learn.20 xr has the ability to capture the attention of students and eliminate distractions. this is particularly true for students with attention deficit disorder, anxiety disorders, or impuls e-control disorder.21 the application of xr goes beyond traditional classroom settings. a case study assessing the benefits of vr in american football training found that players showed an overall improvement of 30 percent after experiencing game plays created by their coaches in a virtual environment.22 although these studies were not conducted in an academic library or university setting, their results are transferable. it is beneficial to academic libraries to provide technologies to their patrons that enhance and advance their learning. currently, xr apps available for purchase on the google app store are still limited. most app development comes from private companies; however, some universities are giving their students the opportunity to develop xr content.23 objectives at brigham young university, we want our vr services to foster the link between academic achievement and virtual reality. in order to do this effectively, our first objective is to determine which vr services will be of most benefit to our patrons. to inform the expansion of future vr services, we conducted a survey of patrons using current vr services in the library. this survey is also intended to help other libraries that are developing vr services and potentially developers information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 3 interested in creating academic content for students. we were primarily interested in user experience, demographics, academic interests in vr, and methods of discovery. methods during one semester, january through april 2018, we asked individuals to complete a questionnaire following their use of the library’s htc vive system. this questionnaire was administered through an online qualtrics survey that was distributed via email to patrons after using the library’s vr equipment. it consisted of thirteen questions that gathered basic demographic information as well as information on patron interests and experiences with the library’s vr services. the complete survey used in this study can be found in appendix a. currently the harold b. lee library at brigham young university offers one htc vive vr system that can be used on site in the science and engineering area of the library. it is primarily operated by student employees who work at the science and engineering reference desk. time slots are reserved through an online registration system on the library’s website. in order to gather more in-depth, qualitative data on patron experience with the library’s vr services, we also conducted a focus group with vr users. we recruited participants by adding a question at the end of the qualtrics survey asking whether the responder would be interested in participating in a focus group. all focus group participants received a complimentary lunch. during the focus group, we asked a series of five questions to gain a deeper understanding of users’ vr experience at the library. in particular, we asked participants to explain what went well during their vr experience in the library, what difficulties they experienced, how they envisioned using vr for both academic and extracurricular purposes, and what type of vr content (e.g., software or equipment) they would like the library to acquire. the focus group facilitator asked follow-up questions for clarification as needed. the session was audio recorded, and participant responses were transcribed and coded for themes. results and discussion demographics the most frequent users of the vr equipment in the library were male students in the science. technology. engineering, or mathematics (stem) disciplines. the percentage of male students at brigham young university is roughly 50 percent but over 70 percent of our survey respondents were male. that stated, there was considerable use among all measured demographics, as shown in figure 1. over one third of responders were not students. university faculty made up 11 percent of responders during the survey period. the proportion of faculty who responded was higher than the university’s faculty-to-student ratio and likely the result of directly advertising the service to non-student university employees. because some users informed librarians that they had brought spouses and children to use the equipment, we estimate that the 7 percent of responders who were neither students nor university employees mostly consisted of family or friends accompanying students or employees. over one third of student responders were majoring in disciplines outside of science, technology, engineering, and mathematics. this number is small when compared to the number of students in these majors across campus (approximately 63 percent of students on campus are not majoring in stem disciplines.); however, it demonstrates that there is an interest in vr technology throughout the university. as the vr services are located in the science and engineering area of the library, it is not surprising that more students majoring information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 4 in these disciplines used these services when compared to students majoring in other disciplines. in fact, 15 percent of responders learned about the services at the reference desk, where they could see other patrons using the vr equipment. the most common discovery method, however, was the various forms of advertisements targeted to both students and employees of the brigham young university, as shown in figure 2. figure 1. demographics. information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 5 figure 2. most effective discovery methods: advertisement and word-of-mouth. only 7 percent of responders identified research or class assignments as their primary reason for using the services. the large majority of use, as shown in figure 3, was simply for entertainment or fun. this was not unexpected, especially as most of the users were trying the technology for the first time (see figure 4). however, because we purchased the equipment with the intent to support academic pursuits on campus, we hoped to see a higher percentage of academic use. figure 3. most responders came because it sounded fun. information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 6 figure 4. most responders were first-time users. faculty use was higher than expected (see figure 5). eleven percent of users during our survey period were faculty. the majority of these responders indicated an interest in potentially using vr technology with their students (see figure 6). while this interest was positive, faculty member suggestions for classroom use remained hypothetical, without any concrete intentions for implementation. this suggests that although faculty interest exists, faculty may need to be informed of specific application ideas in order to be more likely to incorporate this technology into their courses. information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 7 figure 5. faculty were interested in trying the vr equipment. information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 8 figure 6. faculty were interested in using vr academically. a clear majority (72 percent) indicated an intention of returning to the library to use the service again (see figure 7). information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 9 figure 7. most responders intend to return. because our vr services were a small pilot program at the time of the survey, we did not offer a large number of paid apps to users. table 1 displays the most common apps used by survey responders. most users tried google earth during their session, and employees at the reference desk often recommended this app to new users. another common app for new users was the lab, which includes a few small games showcasing the current capabilities of vr. google tiltbrush is an app for creating 3d art. virtual jerusalem is an app that was created by faculty at brigham young university and allows users to walk around and explore the jerusalem temple mount during the time of christ. the fifth-most-used app we offered was 3d organon vr anatomy, which teaches human anatomy. 1. google earth 2. the lab 3. tiltbrush by google 4. virtual jerusalem 5. 3d organon vr anatomy table 1. top five apps used. focus group data we conducted a total of three focus group sessions. each session included between five and eight participants, for a total of twenty-one focus group participants. because we were primarily information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 10 interested in student responses, we limited focus group participants to students enrolled at brigham young university. the participants were asked to describe what did or did not go well during their vr session. when describing what went well during their vr session, many participants responded with positive comments about the quality of service the library employees provided during their session. most participants expressed satisfaction with the number and quality of the apps provided by the library. during all three focus groups, participants mentioned that they liked how easy it was to sign up for the vr services. the most common problems reported by participants related to health or safety concerns, such as feeling dizzy, bumping into objects in the room because of the lack of space, and tripping over the headset wire. other s reported problems related to the level of personal or social comfort with the vr services, such as feeling self-conscious using vr in a semi-open space not exclusively devoted to vr services or being told to be quieter. when asked about ways the library could improve its vr services, the students suggested solutions to many of these problems. a frequent recommendation was that the library dedicate a space to vr. the reasons for this suggestion included minimizing the risk of accidentally bumping into objects, reducing the embarrassment of using the vr equipment in front of spectators, and allowing participants to become more fully immersed in the vr experience without worrying about being too loud. other common suggestions included providing more than one headset for multiple patrons to use for gaming purposes or team projects, acquiring wireless headsets to eliminate wire tripping hazards, and providing more online training videos to reduce reliance on library workers for common troubleshooting problems. participants did not provide actionable suggestions on ways to decrease dizziness while operating vr equipment. when asked about how the students could see themselves using vr academically, many responded with some of the more well-known uses of vr technology, such as potential uses in science, medicine, engineering, and the military. however, some students had a very hard time determining how vr could be applied to humanities fields such as english. after some discussion, most students were able to see the relevance of vr in their field, but some said that they most likely would not pursue those functions of vr, using vr exclusively for extracurricular activities. in contrast to the lack of academic uses envisioned by focus group participants, participants had substantially more ideas about how they would use vr for extracurricular purposes, including playing games for stress relief, exercising, exploring the world, and watching movies. many expressed interest in using vr for extracurricular learning outside their majors, such as virtually being part of significant historic events, exploring ecosystems, and visiting museums or other significant landmarks. students expressed interest in exploring the many possibilities provided by vr technology but were not especially aware of or interested in how vr might apply to their specific field of study unless they were in an engineering, medical, or other science-related discipline. conclusions vr is a rapidly growing field, and academic libraries are already providing students access to this technology. in our study, we found considerable interest across campus in using vr in the library, however the academic interest and use were not as high as we hoped. future marketing to faculty might benefit from specifically suggesting ideas for academic uses or collaboration. even though our current vr services are located at the science and engineering help desk, nearly 40 percent of information technology and libraries march 2020 virtual reality | frost, goates, cheng, and johnston 11 users were not in stem disciplines. this is encouraging and suggests value in marketing future vr services to all library patrons. we also found sufficient patron interest to justify exploring related vr services, such as offering classes on creating content and acquiring less expensive headsets that can be borrowed outside of the library. although this survey was limited to one university, we believe the results can be used to inform other academic libraries as they develop similar vr services. endnotes 1 susan lessick and michelle

conclusions endnotes the “black box”: how students use a single search box to search for music materials kirstin dougan information technology and libraries | december 2018 81 kristin dougan (dougan@illinois.edu) is head, music and performing arts library, university of illinois. abstract given the inherent challenges music materials present to systems and searchers (formats, title forms and languages, and the presence of additional metadata such as work numbers and keys), it is reasonable that those searching for music develop distinctive search habits compared to patrons in other subject areas. this study uses transaction log analysis of the music and performing arts module of a library’s federated discovery tool to determine how patrons search for music materials. it also makes a top-level comparison of searches done using other broadly defined subject disciplines’ modules in the same discovery tool. it seeks to determine, to the extent possible, whether users in each group have different search behaviors in this search environment. the study also looks more closely at searches in the music module to identify other search characteristics such as type of search conducted, use of advanced search techniques, and any other patterns of search behavior. introduction music materials have inherent qualities that present difficulties to the library systems that describe them and to the searchers who wish to find them. this can be exemplified in three main areas: formats, titles, and relationships. first, printed music comes in multiple formats such as full scores, vocal scores, study scores, and parts; and in multiple editions such as facsimiles, scholarly editions, performing editions (of various caliber); each format and edition serving a different purpose or need. related to this, but less problematic, is the variety of sound recording formats available. second, issues resulting from titling practices abound in music, ranging from frequent use of foreign terms, not just in descriptive titles (l'oiseau de feu = zhar-ptitsa = the firebird = feuervogel), but in generic titles as translated by various publishers from different countries (symphony=sinfonie). additionally, musical works often have only generic genre titles enhanced by key and work number metadata, for example symphony no. 1 in c minor. third, music materials present a relationship issue best defined as “one-to-many.” musical works often have multiple sections or songs in them (an aria in an opera or a movement in a symphony), and a cd or a score anthology may contain multiple pieces of music. given these three main challenges presented by music materials, it is possible that those searching for music develop distinctive search habits compared to patrons in other subject areas. this study uses transaction log analysis of the music and performing arts module of a library’s federated discovery tool to determine how patrons search for music materials. it also makes a top-level comparison of searches done using other broadly defined subject disciplines’ modules in the same discovery tool. it seeks to determine, to the extent possible, whether users in each group have different search behaviors in this search environment. the study also looks more closely at mailto:dougan@illinois.edu the “black box” | dougan 82 https://doi.org/10.6017/ital.v37i4.10702 searches in the music module to identify other search characteristics such as type of search conducted, use of advanced search techniques, and any other patterns of search behavior. background since fall 2007 the university of illinois library has had easy search (es), a locally developed search tool designed to aid users in finding results from multiple catalog, a&i, and reference targets quickly and simultaneously. there is a “main” es on the library’s main gateway page that searches a variety of cross-disciplinary tools (see figure 1). figure 1. gateway easy search. on the gateway, users have the option of selecting one of the format tabs to narrow their search to books, articles, journals, or media. when the data for this study was gathered, the journals tab was not present. starting in 2010 many of the subject and branch libraries in the university library created their own es modules with target resources specific to the disciplinary areas they serve. search boxes for these es subject modules are often displayed right on the branch library’s home page, but users can also select these subject module options from the dropdown in the main es (see figure 2). information technology and libraries | december 2018 83 figure 2. gateway dropdown subject choices. the mpal es interface as it appears on the mpal homepage can be seen in figure 3—it was created in 2011. figure 3. mpal easy search interface. the “black box” | dougan 84 https://doi.org/10.6017/ital.v37i4.10702 es is a federated search tool and does not have a central index like most current discovery layer tools. rather, it utilizes broadcast search technologies to target different tools and search them directly. while the gateway es now uses a “bento box” layout to display selected citations from each target, in the first iterations of the tool and still today in the subject modules, users are simply presented with a list of hit counts in each of the target tools (see figures 4 and 5). figure 4. mpal easy search display screen part 1. figure 5. mpal easy search results screen part 2. information technology and libraries | december 2018 85 not shown in the screen captures are the results from various newspaper indexes and reference sources such as oxford music online and the international encyclopedia of dance. literature review many studies have examined patron search behavior using transaction log analysis and other methods over the past few decades. since the appearance of google in 1998, and its vast impact on individuals’ expectations and search behavior, recent studies have looked at user search behavior in tools that initially present a single search box. additional studies have looked at disciplinespecific searching behaviors. general search studies and single search boxes many advantages and disadvantages have been ascribed to tools with single search boxes (whether federated search tools or discovery layers), namely ease and convenience on the one hand, and the lack of precision possible in searching and overwhelming number of results on the other. two companion articles, boyd et al. and dyas-correira, written ten years apart, attempted to visit and revisit these issues.1 results and patron satisfaction can vary based on size of library and number of resources accessed by these tools. these types of tools will never be able to search and display everything and that problem is magnified by the number of resources a library has. holman, porter, and zimerman discovered in independent studies that undergraduates do not search very efficiently or effectively and find library tools difficult to use.2 avery and tracy also found this true for the es tool under discussion in this study: the generation of keywords by many students indicates they often struggled to identify alternative terminology that may have resulted in a more successful search . . . . many students exhibited persistence in their searching, but the selection of search terms, sometimes compounded by spelling problems or problems in search string structure, likely did not yield the most relevant results.3 asher, duke, and wilson state in their study comparing student search strategies and success across a variety of library search tools and google that there were “strong patterns in the way students approached searches no matter which tool they used. . . . students treated almost every search box like a google search box, using simple keyword searches in 81.5 percent (679/829) of the searches observed.”4 dempsey and valenti note students’ infrequent use of limiters such as “peer-review” and “date” in eds, the high non-use and misuse rates of quotation marks, relatively low instances of repeated uncorrected spelling errors, and variance patterns in keyword usage.5 students like federated search tools and discovery layers because of their convenience and ease, as found in studies by armstrong, belliston, and williams et al.6 this is reiterated in asher et al., “despite the fact that they did not necessarily perform better on the research tasks in this study, students did prefer google and google-like discovery tools because they felt that they could get to full-text resources more quickly.”7 this one-box approach could hinder students, as described by swanson and green: the search box became an obstacle in other questions where it should not have been used. in some cases, the search box was viewed as an all-encompassing search of the entire site. the “black box” | dougan 86 https://doi.org/10.6017/ital.v37i4.10702 several students searched for administrative information, research guides, and podcasts in this box.8 lown et al. also found that users hope to access a vast range of information via a single search box. “one lesson is that library search is about more than articles and the catalog. about 23 percent of use of quicksearch took place outside either the catalog or articles modules, indicating that ncsu library users attempt to access a wide range of information from the single search box.”9 search and library use in different disciplines in their study comparing a discovery layer and subject-specific tools, dahlen and hanson found “subject-specific indexing and abstracting databases still play an important role for libraries that have adopted discovery layers. discovery layers and subject-specific indexing and abstracting databases have different strengths and can complement each other within the suite of library resources.”10 they also observed things iterated by previous authors, chiefly that “not all students prefer discovery tools” and “the tools that students prefer may not be those that give them the best results.”11 in addition, they found that default configuration matters in terms of students’ success in and preference for a given tool. fu and thomes found that creating smaller disciplinespecific subsets in discovery tools was beneficial to searchers by reducing results and in creasing the results’ relevance.12 few studies investigate how music students search for music materials. dougan found in her observational study of music students’ search behaviors that they have difficulty forming good searches; misuse quotation marks and other search elements; and at times struggle with finding music materials.13 mayer noted upper-class music students’ frustration with using library tools to find specific works of music, going so far as to state, “the music students agreed that both the discovery layer and the catalog are not effective for music-related searching, for any format.”14 clark and yeager found that students had an easier time searching for media items than music scores, and frequently struggled with search strategy revisions.15 there is more research on the larger information needs of disciplines and creating models for research behavior, and not necessarily specific search processes or constructions.16 whitmire, in her 2002 pre-google article, found that students majoring in the social sciences were engaged in information-seeking behaviors at a higher rate than students majoring in engineering.17 chrzastowski and joseph surveyed graduate students at the university of illinois at urbana– champaign and found that those in the life sciences, physical sciences, and engineering visited the libraries less often than students in other academic disciplines.18 students in the arts and humanities used the library more often than students in other disciplines. collins and stone report that in prior studies of users across different disciplines, arts and humanities users do not account for the biggest users of library materials, their survey found the opposite to be true. 19 when looking at the various student populations in their study, musicians had the highest library usage in terms of items borrowed and almost the highest number of library visits. music users in the study also showed high numbers of hours logged into the library e-resources and highest number of e-resources accessed compared to others in their discipline group (but not as much as other disciplines). however, they show a low number of pdf downloads and low number of e-resources accessed frequently. information technology and libraries | december 2018 87 methodology this study conducted quantitative analysis of easy search (es) data as a whole and from a selection of the subject modules, including the music and performing arts library (mpal) module, using data from the period june 20, 2014 through june 16, 2015. additional quantitative and qualitative analysis was conducted only on the mpal es transaction log data. data from the following subject modules were included in comparative analyses: • funk agricultural, consumer and environmental sciences library (aces) (http://www.library.illinois.edu/funkaces/) • grainger engineering library (http://search.grainger.illinois.edu/top/) • history, philosophy, and newspaper library (hpnl) (http://www.library.illinois.edu/hpnl/) • music and performing arts library (mpal) (http://www.library.illinois.edu/mpal/) • social science, health, and education library (sshel) (http://www.library.illinois.edu/sshel/) • undergraduate library (ugl) (http://www.library.illinois.edu/ugl/) each of these libraries has a search box for es on its home page that is customized to the search targets identified as best for those subject areas by the subject librarians in that library. transaction log data on searches done in es is continuously compiled in a sql database and queries were written to determine certain quantitative measures. searches done in these various subject modules were isolated by a variable in the sql data that indicates whether the search was done in the main gateway es, in the main gateway es but using one of the subject dropdown choices, or from the subject es box directly from that library’s homepage. searches in the six subject modules listed above and in the main es were assessed for the average number of searches per session and the average words per search. further analysis of searches done in the mpal es module used 25,503 sessions conducted on mpal public computers from march 21, 2014 to june 21, 2015, which is a slightly longer timespan than used for the comparative analysis between subject es modules described above. to make this more manageable, only every tenth session was considered, meaning 2,550 sessions were analyzed out of the full set of mpal data. searches were sorted by session id number, which is assigned to each session when a new session is begun. this method kept all strings from one session together, whereas simply sorting by date and string id did not, since multiple sessions can occur simultaneously. a session is a series of user actions (searches and click-throughs) from the same workstation in which there is less than a twenty-minute pause between actions. if there are user actions from the same workstation after a twenty-minute pause, a new session is established, therefore, there is the possibility that some of the sequential sessions were from the same user, but there is no easy way to determine that. the mpal data set was assessed using the following quantitative measures: 1) average number of searches per session and whether session contained a) a single search b) multiple searches for the same thing (either repeated exactly or varied)

3) type of search by index (title/author/keyword) or other advanced search 4) use of boolean, quotation marks, parentheses, etc. 5) use of work or opus numbers or key indications 6) search indicating format (score, cd, etc.) findings comparing the data for searches done in the main es to some of the subject modules (see table 1) shows that the ugl es and the hpnl es have the fewest average searches per session, and the mpal es has the third highest average number of searches per session. the sciences tend to have higher average words per search string values, while mpal has the second lowest average number of words per search. this is not surprising given that the sciences tend to use a lot of journal literature and it is common for researchers to copy and paste such citations into es. whereas in music, as we will see later, keyword searches tend to focus on combinations of the composer’s name and words from the work title, occasionally with other terms added. source sessions

the gateway dropdown from march 21, 2014 through june 21, 2015, there were 25,503 sessions conducted in the mpal es that contained a total of 49,702 searches, resulting in an average of 1.949 searches per session. of the 2,550 mpal search sessions in the study sample, the majority (63.2 percent) consisted of one search.22 this means the patron conducted one search and then left es, presumably clicking into the library catalog or another tool that is a target in es to complete their research. sessions consisting of two to four searches account for 31 percent of sessions, while sessions involving five to nine searches only account for 5 percent of total sessions, and only 32 sessions, or fewer than 1 percent, consist of ten or more searches (see table 2). searches per session number

per session. sessions with multiple searches (n= 946) were evaluated to see whether patrons were searching multiple times for the same thing (either with the same term[s] or with different terms), or whether they were searching for different things. five sessions that were clearly not music-related were removed from the sample. each session was categorized as “same/exact,” “same/different,” or “different.” at times, sessions might include several searches for the same thing using altered strings, in addition to searches for other things. those sessions were coded as “different.” for example: crumb zodiac crumb georgy crumb georgy cromb korean music there were 478 multi-search sessions (50.6 percent) in which patrons searched for different things within their session, 391 sessions (41.3 percent) in which patrons looked for the same thing with differing search strings, and 71 (7.5 percent) in which patrons reiterated the exact same search in each attempt. in the 71 sessions in which patrons used the same exact search the “black box” | dougan 90 https://doi.org/10.6017/ital.v37i4.10702 multiple times, they averaged 2.25 searches. those sessions tagged as “same/exacts” provide an opportunity to try to determine why patrons repeat the same search. common themes include: using too broad a search, searching in wrong place (non-performing-arts–related search), or repeatedly typing in the wrong info (e.g., typos or other errors) and not realizing their mistake. in the 391 sessions in which patrons spent their session searching for the same thing with different search strings, they did so with an average of 2.96 searches. often the variation in the search string was a change in spelling or a minor change in the terms, but sometimes it involved the addition or subtraction of terms, such as starting with morley fitzewilliam virginalists and going to morley fitzewilliam. in another example, we see how music metadata can prove challenging for searchers to format, such as when a patron started with schumann op.68 (without the necessary space between op. and 68), then progressed to album for the young, and finally schumann album for the young. in the 478 sessions in which patrons searched for completely different things within their session, they did so with an average of 4.08 searches per session. in many cases, although the searches were for different items, they were related in some way, either by genre, instrument, or some other element, such as in this example: microjazz color me jazz jamey aebersold play-along vandall jazz jazz piano pieces but sometimes the searches were for very different things: debussy voiles composition as problem mart humal composition as problem debussy ursatz average number (and range) of terms per search in looking at the approximately 4,900 searches included in the sample of 2,550 mpal sessions, without removing the small percentage of duplicate searches, two-term searches are the most common, followed by three-term searches—together accounting for more than half of the searches (55.3 percent). oneand four-term searches are the next most common, together accounting for 25.5 percent of searches (see table 3). in 2012, regular es single-term searches were at almost 60 percent.23 information technology and libraries | december 2018 91 number of terms in search string instances

74 to ten examples each, respectively, while searches with 16 to 20 terms ranged from 8 to 2 examples each, respectively. the following term counts each had only one example in the logs (25, 26, 31, 32, 36, 57). single-term searches types of single-term searches can be broken down into several categories (see table 4). over half (58.4 percent) were searches for personal names or part/all of a work title. some names and work titles are in fact so unique that a one-word search might in fact be successful (e.g., beyoncé, schwanengesang, newsies, or landowska). over a fifth (22.2 percent) were classified as “other or undetermined,” including publisher names, cities, or subject terms. type of one-word search number personal name 260 title 93 instrument/genre 51 tool/location/format 51 call number/barcode/label number 15 other/undetermined 135 table 4. one-term search types. in the tool/location/format category patrons searched for things such as: albums, images, dissertation, rilm, worldcat, jstor, and imslp. while rilm (abstracts of music literature) and worldcat can be found by a search in this tool because they will match on journal or database titles to which we subscribe, a search for imslp [international music score library project] only brings back mentions of imslp in rilm, etc. mpal links to imslp on its webpage, but neither imslp nor the library’s website are targets in es. when patrons only searched for a format, as in a session where a patron first searched for performances, then albums, and then audio cd [sic], it is difficult to know whether the patron expected to be led to a tool that only searched or listed recordings, whether they wanted a list of all of our recordings, or if some other logic was occurring. searchers also used this technique in multi-word searches, such as in the example george gershwin articles. the “black box” | dougan 92 https://doi.org/10.6017/ital.v37i4.10702 single-term searches in the “other/undetermined” category were a mix of subject terms like solfege, tuning, and spectralism. the patron could be trying to find materials related to these topics, examples of them (in the case of solfege), or definitions for them. they also included publisher or label terms such as rubank and puntamayo [sic], and even, on more than one occasion, urls and dois. two-term searches and names the largest segment of the mpal data (31.8 percent) is comprised of two-term searches. the examples show that often a musical work can be easily sought based on the composer’s name and a word from the title, especially in cases where it is a common title but adding the composer’s name makes it unique (e.g., ligeti requiem). sometimes the patron only knows the work’s characteristics and not its proper name (e.g., lakme duet). patrons do attempt to search for topical material using only two words, and that is not likely enough for a good topic search in most cases, such as in the example mahler dying. sometimes phonetic spellings are employed such as woozy wick followed by woyzeck (which is both a play and a film with this spelling but could also potentially be a misspelling of berg’s opera wozzeck). another example is image cartier followed by images quartier. personal names are frequently seen in two-term search strings. occasional use of foreign versions of names is observed, e.g., georgy crumb. it is difficult to know if these are typos or an artifact of our high international student population. as with any search that contains only a name, it is impossible to know whether the searcher was looking for materials by that individual or information about them. additionally, when current faculty names are searched, it is difficult to know whether patrons are looking for contact information for them, or scores or recordings by them. also observed in name searches is the phenomena of patrons repeating their search with a change in order of names, such as bryan gilliam and then gilliam bryan. this occurs with other two-word searches as well, such as a change from introitus gubaidulina to gubaidulina introitus. switching the order of the words in a search no longer makes a difference in most search tools (although in some catalogs, of course, it was once required to formulate an author search as last name, first name). there is still the occasional use of comma in ln, fn searches here. echoing the results of an earlier study that asked students what data points they used in searching, only occasionally did searches in this data set incorporate specific performers combined with a particular piece or composer: franck mutter, or for a particular edition: idomeneo barenreiter.24 sometimes names/titles were combined with format, such as a session in which a patron searched for hedwig images and then hedwig photo. here it is hard to tell if they are looking for pictures of a fictional owl or images from productions of hedwig and the angry inch, or something else. names are also frequently combined with work numbers instead of title words, such as mozart k.395 and moscheles op.73. search strings in the “other/undertermined” category sometimes included what appears to be an author/date search, perhaps for an article, such as mccord 2006. long search strings on the other end of the spectrum, the vast majority of the ten-plus word string searches are for performing arts items, but some were in other subject areas. these long searches are often citations that have been copied and pasted, which can be discerned from the use of punctuation and capitalization, like “welded in a single mass”: memory and community in london’s concert halls information technology and libraries | december 2018 93 during the first world war.25 it is very common in general gateway es searches to see an entire citation pasted in,26 but less common in the mpal module. searches such as this are often truncated through iteration to make the search more generic (see table 5). given easy search’s doi search recognition function, the longest version of this search would have worked had the doi been correct, but the correct doi number lacks the “.2” at the end (see table 6, query 1). the middle three searches (#s 2-4) failed because none of the a&i services that include this citation use hess, j. for the author’s name, but instead use her full first name (juliet). other examples showed that even when patrons use the exact citation, their search might not be successful if the citation formatting did not match that of the database(s) in which the article was indexed. query # query string 1 hess, j. (2014). radical musicking: towards a pedagogy of social change. music education research, 16(3), 229-250. doi: 10.1080/14613808.2014.909397.2). 2 hess, j.

searches were long because the patron included additional information such as in this example: bernstein, leonard. arranger: jack mason. title: west side story-selections (for symphonic "full" orchestra piano-conductor score). edition/publisher: hal leonard corporation. it is hard to tell if this was a copy and paste from another source such as a publisher catalog, or if the patron was trying to be very precise. in any case, this search was not successful, but would have been had the searcher omitted extraneous information such as the terms “arranger” and “edition/publisher.” type of index search—title/author/keyword and adding subsets or tools easy search does have an advanced search function with indexes for title and author, although it is rarely used by patrons. including repeated searches, searches done selecting the “title” index only numbered 207, or fewer than 10 percent of the sample. searches done selecting “author” were even scarcer, at 141(5.5 percent). the remaining ~2,300 searches in the sample were conducted using the default keyword search. occasionally there was a misuse of index searching, such as: ti: js bach english suite ti: scarlatti sonatas ti: haydn cello concerto d in these examples, composer name is included in a title index search. it is unclear whether searchers do not realize that they have selected something other than a keyword search, or whether people inherently think of the composer’s name as part of the title. later in this paper the phenomenon of searches using possessive name forms is discussed, which may be associated. the “black box” | dougan 94 https://doi.org/10.6017/ital.v37i4.10702 patrons have the option to start from the main library gateway and perform a search in es, and in the advanced search screen can choose other subject modules such as arts and humanities, l ife sciences, and so forth, and/or types of tools to cross-search (see figure 6). patrons chose the music and performing arts tool subset in 161 sessions. figure 6. easy search advanced search screen. the vast majority of the time (4,557 searches or 93 percent), patrons chose to start from the mpal es on the mpal homepage and do a basic search there, but 179 times patrons started from the mpal es and chose other subsets through the advanced search.27 given our large music education program, logically, some patrons made tool choices that included the music subset and the education and/or social science subsets. but sometimes patrons chose every or almost every option available across multiple unrelated subject areas, which likely made for a very unwieldy result set. information technology and libraries | december 2018 95 use of boolean operators, quotation marks, parentheses, truncation, etc. as in most search tools, there are several ways in es to conduct more sophisticated searches. however, patrons do not employ these techniques often, in part because they don’t always have to. in most older catalogs (including our classic voyager opac), searchers had to use boolean terms in capital letters, whereas in vufind and worldcat boolean and is now implied between terms. in the 159 examples of boolean logic in the searches, and is most common term used. interestingly, some researchers used plus signs instead of and (as they might in google), not just between individual words, but in between multi-word segments of the string (without employing quotation marks). however, the + sign, like and, is ignored/implied by es. berg + warm die lufte progressive studies for trumpet progressive studies for trumpet + john miller progressive studies for trumpet (john miller) new orleans + bossa nova johnny alf + brazil dick farney + brazil dick farney + booker pittman in some cases, the use of boolean did not seem intentional, that is, the term “and” appears as part of a common phrase (especially for instrument combinations), such as in webern violin and piano. only a handful of the boolean searches included examples of or and not, which seemed to stem from a class assignment designed by a professor, as the search strings are all very similar. one set is below: machaut not mass machaut or mass machaut and mass machaut mass notre dame machaut mass machaut and mass the “black box” | dougan 96 https://doi.org/10.6017/ital.v37i4.10702 commas were sometimes seen to stand in for boolean operators in a sense, or at least to separate search concepts, like the plus signs above, but were not counted in the total uses of boolean terms cited above. they are ignored by es. rachmaninoff, moment music planet, holst city noir, john adams piazzolla, flute and marimba mussorgsky, pictures at an exhibition, manfred schandert searchers used quotation marks on occasion (n=162) to keep phrases together, and parentheses were also used in this manner eight times (although they are ignored by es), such as in these examples: preludes and fugues (well-tempered clavier) cohen chaconne (from partita in d minor, bwv 1004) in some cases, searchers did not seem to grasp the function of quotation marks, as in this example: “snowforms" raymond murrey schafer, which was also observed by avery and tracy.28 truncation symbols can be another powerful tool in a searcher’s arsenal, but examples of their use in the transaction logs show that most searchers who attempt to use them do not understand them, such as in the examples doctor atomic?, boethius music,* and: orchestra* history history of the orchestra orchest* history orchestr* history orchestra history orchestral history in fact, the current library catalog assists users by automatically applying truncation logic so that “symphony” returns results for “symphonies” and vice versa. it is doubtful that this is generally known among users and likely functions in a manner transparent to most of them. work numbers and key indications searching by music metadata elements such as work or opus numbers and key designations has always proved challenging in online search environments given that numbers and single letters can appear in other parts of the catalog record with different meanings (e.g., 1 part instead of symphony no. 1). added to this is the difficulty of describing items that contain multiple works— the item’s title might be “mozart’s complete symphonies” or “beethoven symphonies 1-6” without information technology and libraries | december 2018 97 complete work details provided. nevertheless, 134 searches had some form of work number included, and 36 searches included a key indication. fantasie in f# minor presto georg philipp telemann and concerto en ut mineur j.c. bach are further examples of why a work’s key is hard to search by, one because of the use of the french solfege syllable “ut” and one because it includes a sharp symbol (#).29 the difficulties this can cause often led searchers to try various permutations of their search. mozart concerto g major sam franko; mozart concerto k 283 sam franko; scores; mozart violin concerto g major; mozart violin concerto g major sam franko; mozart violin concerto; sonata g major flute cpe bach sonata g major flute bach hamburger sonata flute cpe bach hamburger sonata hamburger sonata it is counterintuitive to searchers that including specific details in their search string might not help, but that is in fact the case in many online catalogs. searchers often run into the question of how or if to include the work indicator (op., k., bwv, etc.), which can lead to a “misuse” of this extra data such as in mozart k501 and mahler symphony no.9 (no spaces). another observation includes the use of what the author calls musicians’ shorthand. that is, those familiar with classical repertoire will know that examples such as sibelius 1 and mahler 5 are searches for symphonies even though they do not say so, but it will be harder, if not impossible, for the catalog to interpret that, leaving the searcher to sort through many extra results. in addition is the long-standing issue of whether to enter the number as “1”, “1st”, or “first” and whether the system can interpret these against the form of the number present in the catalog record. search by format or edition type in forty-seven examples searchers used format terms in their searches, including score, vocal score, full score, dvd, performance recordings, albums, and audio cd as well as the following: prokofiev romeo and juliet orchestra parts orchestra excerpts prokofiev romeo and juliet viola the “black box” | dougan 98 https://doi.org/10.6017/ital.v37i4.10702 tosca harp part assassins cd saxophone article in fifteen examples searchers searched for edition types including urtext, facsimile, critical edition, and complete works. in the latter case they occasionally used the word “complete” and the composer’s name, such as complete schumann or complete webern. unfortunately, this approach will often not be successful, because even though the term “complete works” is used colloquially by musicians, the titles of such editions are often something else (and often in a foreign language, such as “opera omnia”). other observations on formulation of searches searching by call numbers and recording label numbers while some catalogs allow call number searches, our current instance of vufind does not have a call number index, and keyword searching for them only works in some instances.30 but while call number searching does not work well in vufind (e.g., it has to be done as a keyword search and not a call number index search like in voyager), it still works in es because it is searching by keywords. there were thirty-two examples of searches in mpal’s es where patrons used entire call numbers or the first part of a classification number to find related materials: count basie biography count basie ml 410 duke ellington ml 410 duke ellington bibiliography it is also not unrealistic to think that patrons might want to search by a recording’s label number, since most catalogs provide search options for isbns and issns for print materials. searchers attempted this in a handful of searches like lpo-0014,31 7.24356e+11,32 and 777337-2.33 unfortunately this information is not usually reflected in mpal’s catalog records. common descriptions, natural language queries, genre queries, and context words as mentioned already with the examples mahler 1 and complete works, patrons regularly search with terms and phrases that make sense to them or that are used colloquially when discussing music and sources, which may or may not be in the bibliographic record. additional examples in the data set include: handel messiah critical edition rodelinda in italian mamma mia! book [for the text of a musical] grove encyclopedia [the title of this is in fact “dictionary” not “encyclopedia”] mgg sachteil [the abbreviation for musik in geschichte und gegenwart and the name for a section of it] information technology and libraries | december 2018 99 dance collection the last example in the list is particularly intriguing—somewhat like the earlier search examples of performances and albums, one wonders if the patron hoped to find everything in that category and then be able to browse, however it is hard to know what the searcher anticipated getting in return. sometimes natural language queries appear, often in an attempt to find a smaller part of a larger work, such as the slow movement of brahms's first symphony, anonymous chant from vespers for christmas day, and chaconne (from partita in d minor, bwv 1004); or for things other than musical works, such as in reviews of stravinsky article by robert craft. another variation on natural language or colloquial searches is the use of the possessive form of composer names. although not common (23 examples), patrons do this when searching for composer and title of a work, e.g., verdi's requiem. it seems unlikely that people do this when searching for books or other works, but musicians make works possessive to the composer, such as in the examples mendelssohn's violin concerto, to differentiate between pieces with the same form/generic title. in rare cases searchers used the term “by,” such as jeptha by carrissimi. genre searches such as south indian vocal music and hindustani classical music show that people may want to search the way they might in pandora or itunes, although it is possible this person was looking for secondary materials and not recordings or scores: pop female pop women pop contemporary pop searchers also exhibit a desire to find things by genre and instrument or voice type, such as soprano arias [which is ‘high voice’ in the lc subject heading], mozart satb sanctus, and baroque arias for medium voice. other examples include marimba literature, organ literature, and organ techniques. catalogs do not necessarily aid in these types of searches, even though they are natural constructions for users. sometimes searchers add context words to their search like they would in google in a way that will not necessarily help them in the catalog, such as daniel read composer. discussion even given the difficulties of searching for music materials, mpal patrons have embraced es—its module has almost as many searches as the undergraduate library’s, which serves a much larger population. it also has twice as many searches as the social science, health, and education library module, which also serves a much larger population than mpal. one of the possible reasons for this is the fact that mpal was an early adopter of developing an es subject module that could be searched from our homepage, which means our patrons have had longer to grow accustomed to using it. mpal has lower average words-per-search ratio (3.375 or 3.349 depending on data set) than most other es modules, likely because there are more composer plus title keyword searches for musical works and not as many pasted article citation searches, which tend to be longer. this is supported by the comparison of the average number of words in searches done in the gateway books tab the “black box” | dougan 100 https://doi.org/10.6017/ital.v37i4.10702 (4.048) vs. the gateway articles tab (6.35). in addition, although twoand three-word searches are most common, mpal has a significant number of single-word searches (12.4 percent). such searches can work in music, when there are unique titles like turandot and treemonisha that are unlikely to appear for more than one composer or as terms in other disciplines. for this same reason, singleor even two-word searches are unlikely to be effective in most other disciplines. at around seven words per search a transition in search patterns occurs. eight word and longer search strings are almost always some version of a title of a book, article, chapter or dissertation, etc. and strings with six words and fewer tend to be topical searches or combination composer/piece searches. other transaction log studies of es have shown that “title searching and results display—of journal titles, article titles, and book titles—is being heavily employed by users.”34 however, in music, where title alone may not be sufficient to identify and retrieve a musical work, searches with a combination of composer name and elements of the title and/or additional information will always be most prevalent. search location appropriateness and context even though discovery layers and federated search tools help with minimizing the number of silos and places in which scholars need to search, there are still issues with patrons attempting to use the es box to find things it is not designed to find.35 searchers see a box and search, without always understanding the context. this can happen on multiple levels. the mpal page clearly states that the mpal es box searches for arts-related things, but obviously patrons do not always see or comprehend this, even after they type in many queries that do not provide (good) results. this is likely related to the number of visitors to mpal from other disciplines who do not realize that there are various differently scoped versions of es. the following example could be a theatre set construction related search, which would work only moderately well in our tool. or, it may have been conducted by an architecture or structural engineering student, who would have better luck using a different es module. light weigh [sic] structures in architecture building research the evolving design vocabulary of fabric structure the engineering discipline of tent structures building research jan/feb 1972:22 it would be ideal if the system was smart enough to make suggestions: “you appear to need architecture resources—if you are not finding what you need, might we suggest tool x, y, or z?” while es does this to an extent when it can in the generic es, it does not do so in the subject modules, and in reality, can only go so far. it raises the question of whether we are we doing patrons a disservice by offering pre-defined subject modules. while this approach has some benefits for most users, it also creates different challenges for some. mpal’s es does not target all available relevant online tools and neither does the general es, so interdisciplinary researchers still need to be cautious of silos, even well-intentioned ones created by librarians or traditional information technology and libraries | december 2018 101 ones created by vendors. it is difficult to inform patrons of this in one-box search settings—they see the box and are eager to get started without first having to read a lengthy set of instructions. search location context is also important when patrons use es to try to find things that are described or linked on our website and not in es, such as for any of our named special collections. patrons also use es to find tools such as naxos, jstor, worldcat, and librarysource, some of which are targeted by es and some of which are not. es will at least provide a link to a tool, however (see figure 7). figure 7. easy search post-search suggestion. these particular tools are all also linked from the mpal website (in fact, naxos is linked further down the home page from the es box) and we also have a separate tool that enables one to search for databases and online journals by name. on some occasions, searchers used es to look for help using library tools, such as in the following example: rilm retrieval rilm using rilm the library website, not the discovery layer, is a better tool for finding instructions, since help information is currently delivered via various libguides. however, this is not intuitive to patrons. on a related note, it is interesting to consider whether patrons searching for specific tools such as imslp expect to find results from non-library resources in our search layers, or if they simply do not differentiate in their minds what is an open tool and what is a library subscription tool. patron knowledge level many of the observations of this study are related to known-item searching, since a large percentage of people looking for music materials are looking for specific pieces of music. earlier studies show that it is difficult to search for something if you do not know what it is.36 this can be seen in examples like ombramaifu handel (should be ombra mai fu) or the interworkings of tennis (which was followed by the correct inner game of tennis). topical searches can be especially difficult in any subject when the patron does not quite know how to put what they want into words (or literally does not know the right words, especially in the case of our many patrons for whom english is not their first language). the “black box” | dougan 102 https://doi.org/10.6017/ital.v37i4.10702 qualtize musical tension spell change click: kw:qualitize musical

tension measuring musical tension this echoes head and eisenberg’s 2009 findings and dempsey and valenti’s 2016 findings.37 shortcomings of the easy search tool this study helped illuminate some shortcomings in es. sometimes the search formulation changes from es to the target, for example cramer preludes in es becomes all(cramer preludes) [a bound phrase] in one target, resulting in many fewer results than if the search had been done in the native interface. patrons may not realize this as they are searching. in another case there were no results for danças folclóricas brasileiras e suas aplicações educativas but removing the diacritics retrieves this title in our catalog, so it appears that diacritics do not function in es (at least when vufind is the target)—something that may not be apparent to searchers and hopefully can be addressed in the code. further research additional analysis could be done on this data set, including assessing whether searches were for known items or topics, and more specifically whether for articles, books, scores, or recordings. however, in many cases it is difficult to tell if a patron is looking for a score, recording, or information about a piece or composer. other research on es shows over half of searches (just over 58 percent in 2015) in the main es are for known items.38 this percentage is likely to be much higher in mpal’s es. with an enhanced data set it would also be possible to identify which target tools searchers are choosing most often. conclusion while many patrons (and librarians) are eager for a tool that can truly search everything, we are not there yet. some have tried to make music-specific interfaces for library catalogs, but this work is not widespread.39 perhaps because music students are often searching for things other than articles it would be better to have one tool that searches the catalog and streaming media tools information technology and libraries | december 2018 103 and one that only searches article indexes. some schools have taken this approach—configuring their discovery layer indexes to include article content but not the local catalog. there were several observations in this data of patron search behavior are not fully supported by library systems in all cases, but perhaps should be (e.g., use of + signs, searching by record label numbers or genre names/types of music/formats). in some cases, this is an issue with the metadata standards in use and in others it is about needing more flexible search options based on the metadata that we already have. newcomer et al. discuss this in their article outlining music discovery requirements.40 tools like easy search and discovery layers solve some problems for users but can create others. dedicated library catalogs are still generally the best tools for finding scores and recordings in our physical (and some online) collections, but not all libraries offer that tool anymore, instead offering a discovery layer as the primary search tool. in those cases, serious consideration needs to be given to facets, the ability to limit by format, and especially the frbrization of items, which is particularly problematic for music. additionally, there is a continued need for targeted instruction for music library users, because not only are the tools used in libraries less than perfect, the inherent challenges in searching for music because of its formats and titles are aggravated by musicians’ use of shorthand and colloquialisms to describe music materials. endnotes 1 john boyd et al., “the

research conclusion endnotes 24 information technology and libraries | march 2011 ruben tous, manel guerrero, and jaime delgado semantic web for reliable citation analysis in scholarly publishing nevertheless, current practices in citation analysis entail serious problems, including security flaws related to the publishing process (e.g., repudiation, impersonation, and privacy of paper contents) and defects related to citation analysis, such as the following: ■■ nonidentical paper instances confusion ■■ author naming conflicts ■■ lack of machine-readable citation metadata ■■ fake citing papers ■■ impossibility for authors to control their related citation data ■■ impossibility for citation-analysis systems to verify the provenance and trust of citation data, both in the short and long term besides the fact that they do not provide any security feature, the main shortcoming of current citation-analysis systems such as isi citation index, citeseer (http:// citeseer.ist.psu.edu/), and google scholar is the fact that they count multiple copies or versions of the same paper as many papers. in addition, they distribute citations of a paper between a number of copies or versions, thus decreasing the visibility of the specific work. moreover, their use of different analysis databases leads to very different results because of differences in their indexing policies and in their collected papers.3 to remedy all these imperfections, this paper proposes a reference architecture for reliable citation analysis based on applying semantic trust mechanisms. it is important to note that a complete or partial adoption of the ideas defended in this paper will imply the effort to introduce changes within the publishing lifecycle. we believe that these changes are justified considering the serious flaws of the established solutions, and the relevance that citation-analysis systems are acquiring in our society. ■■ reference architecture we have designed a reference architecture that aims to provide reliability to the citation and citation-tracking lifecycle. this architecture is based in the use of digitally signed semantic metadata in the different stages of the scholarly publishing workflow. as a trust scheme, we have chosen a public key infrastructure (pki), in which certificates are signed by certification authorities belonging to one or more hierarchical certification chains.4 trust scheme the goal of the architecture is to allow citation-analysis systems to verify the provenance and trust of machinereadable metadata about citations before incorporating analysis of the impact of scholarly artifacts is constrained by current unreliable practices in cross-referencing, citation discovering, and citation indexing and analysis, which have not kept pace with the technological advances that are occurring in several areas like knowledge management and security. because citation analysis has become the primary component in scholarly impact factor calculation, and considering the relevance of this metric within both the scholarly publishing value chain and (especially important) the professional curriculum evaluation of scholarly professionals, we defend that current practices need to be revised. this paper describes a reference architecture that aims to provide openness and reliability to the citation-tracking lifecycle. the solution relies on the use of digitally signed semantic metadata in the different stages of the scholarly publishing workflow in such a manner that authors, publishers, repositories, and citation-analysis systems will have access to independent reliable evidences that are resistant to forgery, impersonation, and repudiation. as far as we know, this is the first paper to combine semantic web technologies and public-key cryptography to achieve reliable citation analysis in scholarly publishing. i n recent years, the amount of scholarly communication brought into the digital realm has exponentially increased.1 this no-way-back process is fostering the exploitation of large-scale digitized scholarly repositories for analysis tasks, especially those related to impact factor calculation. the potential automation of the contribution– relevance calculation of scholarly artifacts and scholarly professionals has attracted the interest of several parties within the scholarly environment, and even outside of it. for example, one can find within articles of the spanish law related to the scholarly personnel certification the requirement that the papers appearing in the curricula of candidates should appear in the subject category listing of the journal citation reports of the science citation index.2 this example shows the growing relevance of these systems today. ruben tous (rtous@ac.upc.edu) is associate professor, manuel guerrero (guerrero@ac.upc.edu) is associate professor, and jaime delgado (jaime.delgado@ac.upc.edu) is professor, all in the departament d’arquitectura de computadors, universitat politècnica de catalunya, barcelona, spain. semantic web for reliable citation analysis in scholarly publishing | tous, guerrero, and delgado 25 might send a signed notification of rejection. we feel that the notification of acceptance is necessary because in a certain kind of curriculum, evaluations for university professors conditionally accepted papers can be counted, and in other curriculums not. the camera-ready version will be signed by all the authors of the paper, not only the corresponding author like in the paper submission. after the camera-ready version of the paper has been accepted, the journal will send a signed notification of future publication. this notification will include the date of acceptance and an estimate date of publication. finally, once the paper has been published, the journal will send a signed notification of publication to the author. the reason for having both notification of future publication and notification of publication is that, again, some curriculum evaluations might be flexible enough to count papers that have been accepted for future publication, while stricter ones state explicitly that they only accept published papers. once this process has been completed, a citationanalysis system will only need to import the authors’ ca certificates (that is, the certificates of the universities, research centers, and companies) and the publishers’ ca certificates (like acm, ieee, springer, lita, etc.) to be able to verify all the signed information. a chain of cas will be possible both with authors (for example, university, department, and research line) and with publications (for example, publisher and journal). ■■ universal resource identifiers to ensure that authors’ uris are unique, they will have a tree structure similar to what urls have. the first level element of the uri will be the authors’s organization (be it a university or a research center) id. this organization id will be composed by the country code top-level domain (cctld) and the organization name, separated by an underscore.5 the citation-analysis system will be responsible for assigning these identifiers and ensuring that all organizations have different identifiers. then, in the same manner, each organization will assign second-level elements (similar to departments) and so forth. author’s ca_id: <cctld>_<a_ca_name> example: es_upc author ’s uri: author://<a_ca_id1>/<a_ca_ id2> . . . <a_ca_idn>/<author_firstname>.<author_ familyname> example: author://es_upc.dac/ruben.tous (in this example “es” is the cctdl for spain, upc (universitat politècnica de catalunya) is the university, and dac (departament d’arquitectura de computadors) is the department. them into their repositories. as a collateral effect, authors and publishers also will be able to store evidences (in the form of digitally signed metadata graphs) that demonstrate different facts related to the creating–editing–publishing process (e.g., paper submission, paper acceptance, and paper publication). to achieve these goals, our reference architecture requires each metadata graph carrying information about events to be digitally signed by the proper subject. because our approach is based in a pki trust scheme, each signing subject (author or publisher) will need a public key certificate (or identity certificate), which is an electronic document that incorporates a digital signature to bind a public key with an identity. all the certificates used in the architecture will include the public key information of the subject, a validity period, the url of a revocation center, and the digital signature of the certificate produced by the certificate issuer’s private key. each author will have a certificate that will include as a subject-unique identifier the author ’s universal resource identifier (uri), which we explain in the next section, along with the author ’s current information (such as name, e-mail, affiliation, and address) and previous information (list of former names, e-mails, and addresses), and a timestamp indicating when the certificate was generated. the certification authority (ca) of the author’s certificate will be the university, research center, or company with which the author is affiliated. the ca will manage changes in name, e-mail, and address by generating a new certificate in which the former certificate will move to the list of former information. changes in affiliation will be managed by the new ca, which will generate a new certificate with the current information. since the new certificate will have a new uri, the ca also will generate a signed link to the previous uri. therefore the citation-analysis system will be able to recognize the contributions signed with both certificates as contributions made by the same author. it will be the responsibility of the new ca to verify that the author was indeed affiliated to the former organization (which we consider a very feasible requirement). every time an author (or group of authors) submits a paper to a conference, workshop, or journal, the corresponding author will digitally sign a metadata graph describing the paper submission event. although the paper submission will only be signed by the corresponding author, it will include the uris of all the authors. journals (and also conferences and workshops) will have a certificate that contains their related information. their ca will be the organization or editorial board behind them (for instance, acm, ieee, springer, lita, etc.). if a paper is accepted, the journal will send a signed notification of acceptance, which will include the reviews, the comments from the editor, and the conditions for the paper to be accepted. if the paper is rejected, the journal 26 information technology and libraries | march 2011 ■■ microsoft’s conference management toolkit (cmt; http://cmt.research.microsoft.com) is a conference management service sponsored by microsoft research. it uses https to provide confidentiality, but it is a service for which you have to pay. although some of the web-based systems provide confidentiality through https, none of them provides nonrepudiation, which we feel is even more important. this is so because nonrepudiation allows authors to certify their publications to their curriculum evaluators. our proposed scheme always provides nonrepudiation because of its use of signatures. curriculum evaluators don’t need to search for the publisher’s website to find the evaluated author’s paper. in addition, our proposed scheme allows curriculum evaluations to be performed by computer programs. and confidentiality can easily be achieved by encrypting the messages with the public key of the destination of the message. it should not be difficult for authors to obtain the public key for the conference or journal (which could be included in its “call for papers” or included on its webpage). and, because the paper-submission message includes the author’s public key, notifications of acceptance, rejection, and publication can be encrypted with that key. ■■ modeling the scholarly communication process citation analysis systems operate over metadata about the scholarly communication process. currently, these metadata are usually automatically generated by the citation-analysis systems themselves, generally through a programmatic analysis of the scholarly artifacts unstructured textual contents. these techniques have several drawbacks, as enumerated already, but especially regarding the fact that there is metadata that cannot be inferred from the contents of a paper, like all the aspects of the publishing process. to allow citation-analysis systems accessing metadata about the entire scholarly artifacts lifecycle, we suggest a metadata model that captures a great part of the scholarly domain static and dynamic semantics. this model is based on knowledge representation techniques in semantic web, such as resource description framework (rdf) graphs and web ontology language (owl) ontologies. metadata and rdf the term “metadata” typically refers to a certain data representation that describes the characteristics of an information-bearing entity (generally another data representation such as a physical book or a digital video file). metadata plays a privileged role in the scholarly creations’ uris are built in a similar manner to authors’ uris. but it this case, the use of the country code as part of the publisher’s id is optional. because a creation and its metadata evolve through different stages (submission and camera-ready), we will use different uris for each phase. we propose the use of this kind of uri instead of other possible schemes such as the digital object identifier (doi), because the ones proposed in this paper has the advantage of being human readable and contain the cas chain.6 of course, that doesn’t mean that once published a paper cannot obtain a doi or another kind of identifier. publisher’s ca_id: <p_ca_id> or <country_ code>_<p_ca_id> examples: lita and it_italianjournalofzoology creation’s uri: creation://<p_ca_id1> . . . <p_ ca_idn>/<creation_id> example: creation://lita.ital/vol27_num1_ paper124 confidentiality and nonrepudiation nowadays, some conferences manage their paper submissions and notifications of acceptance (with their corresponding reviews) through e-mail, while others use a web-based application, such as edas (http://edas.info/). the e-mail-based system has no means of providing any kind of confidentiality. each router through which the e-mail travel can see their contents (paper submissions and paper reviews). the web-based system can provide confidentiality through http secure (https), although some of the most popular applications (such as edas and myreview) do not provide it; their developers may not have thought that it was an important feature. the following is a short list of some of the existing web-based systems: ■■ edas (http://edas.info/) is probably the most popular sytem. it can manage a large number of conferences and special issues of journals. it does not provide confidentiality. ■■ myreview (http://myreview.intellagence.eu/index .php) is an open-source web application distributed under the gpl license for managing the paper submissions and paper reviews of a conference or journal. myreview is implemented with php and mysql. it does not provide confidentiality. ■■ conftool (http://www.conftool.net) is another web-based management system for conferences and workshops. a free license of the standard version is available for noncommercial conferences and events with fewer than 150 participants. it uses https to provide confidentiality. semantic web for reliable citation analysis in scholarly publishing | tous, guerrero, and delgado 27 the purpose of the reference architecture described in this paper, we do not instruct which of the two described approaches for signing rdf graphs is to be used. the decision will depend on the implementation (i.e., on how the graphs will be interchanged and processed). owl and an ontology for the scholarly context to allow modeling the scholarly communication process with rdf graphs, we have designed an owl description logic (dl) ontology. owl is a vocabulary for describing properties and classes of rdf resources, complementing rdfs’s capabilities for providing semantics for generalization hierarchies of such properties and classes. owl enriches the rdfs vocabulary by adding, among others, relations between classes (e.g., disjointness), cardinality (e.g., “exactly one”), equality, richer typing of properties, characteristics of properties (e.g., symmetry), and enumerated classes. owl has the influence of more than ten years of dl research. this knowledge allowed the set of constructors and axioms supported by owl to be carefully chosen so as to balance the expressive requirements of typical applications with a requirement for reliable and efficient reasoning support. a suitable balance between these computational requirements and the expressive requirements was achieved by basing the design of owl on the sh family of description logics.10 the language has three increasingly expressive sublanguages designed for different uses: owl lite, owl dl, and owl full. we have chosen owl dl to define the ontology for capturing the static and dynamic semantics of the scholarly communication process. with respect to the other versions of owl, owl dl offers the most expressiveness while retaining computational completeness (all conclusions are guaranteed to be computable) and decidability (all computations will finish in finite time). owl dl is so named because of its correspondence with description logics. figure 3 shows a simplified graphical view of the owl ontology we have defined for capturing static and dynamic semantics of the scholarly communication process. figure 4, figure 5, and figure 6 offer a (partial) tabular representation of the main classes and properties of the ontology. in owl, properties are independent from classes, but we have chosen to depict them in an object-oriented manner to improve understanding. for the same reason we have represented some properties as arrows between classes, despite this information being already present in the tables. uris do not appear as properties in the diagrams because each instance of a class will be an rdf resource, and any resource has a uri according to the rdf model. these uris will follow the rules described in the above section, “reference architecture.” it’s worth mentioning that the selection of the included properties has been based in the study of several metadata formats and standards, such as dublin communication process by helping identify, discover, assess, and manage scholarly artifacts. because metadata are data, they can be represented through any the existing data representation models, such as the relational model or the xml infoset. though the represented information should be the same regardless of the formalism used, each model offers different capabilities of data manipulation and querying. recently, a not-so-recent formalism has proliferated as a metadata representation model: rdf from the world wide web consortium (w3c).7 we have chosen rdf for modeling the citation lifecycle because of its advantages with respect to other formalisms. rdf is modular; a subset of rdf triples from an rdf graph can be used separately, keeping a consistent rdf model. it therefore can be used with partial information, an essential feature in a distributed environment. the union of knowledge is mapped into the union of the corresponding rdf graphs (information can be gathered incrementally from multiple sources). rdf is the main building block of the semantic web initiative, together with a set of technologies for defining rdf vocabularies like rdf schema (rdfs) and the owl.8 rdf comprises several related elements, including a formal model and an xml serialization syntax. the basic building block of the rdf model is the triple subjectpredicate-object. in a graph-theory sense, an rdf instance is a labeled directed graph consisting of vertices, which represent subjects or objects, and labeled edges, which represent predicates (semantic relations between subjects and objects). coming back to the scholarly domain, our proposal is to model static knowledge (e.g., authors and papers metadata) and dynamic knowledge (e.g., “the action of accepting a paper for publication,” or “the action of submitting a paper for publication”) using rdf predicates. the example in figure 1 shows how the action of submitting a paper for publication could be modeled with an rdf graph. figure 2 shows how the example in figure 1 would be serialized using the rdf xml syntax (the abbreviated mode). so, in our approach, we model assertions as rdf graphs and subgraphs. to allow anybody (authors, publishers, citation-analysis systems, or others) to verify a chain of assertions, each involved rdf graph must be digitally signed by the proper principal. there are two approaches to signing rdf graphs (as also happens with xml instances). the first approach applies when the rdf graph is obtained from a digitally signed file. in this situation, one can simply verify the signature on the file. however, in certain situations the rdf graphs or subgraphs come from a more complex processing chain, and one could not have access to the original signed file. a second approach deals with this situation, and faces the problem of digitally signing the graphs themselves, that is, signing the information contained in them.9 for 28 information technology and libraries | march 2011 note that instances of submitted and accepted event classes will point to the same creation instance because no modification of the creation is performed between these events. on the other hand, instances of tobepublished and published event classes will point to different creation instances (pointed by the cameraready and publishedcreation properties) because of the final editorial-side modifications to which a work can be subject. ■■ advantages of the proposed trust scheme the following is a short list of security features provided by our proposed scheme and attacks against which our proposed scheme is resilient: core (dc), dc’s scholarly works application profile, vcard, and bibtex.11 figure 4 shows the class publication and its subclasses, which represent the different kinds of publication. in the figure, we only show classes for journals, proceedings, and books. but it could obviously be extended to contain any kind of publication. figure 5 contains the classes for the agents of the ontology (i.e., the human beings that author papers and book chapters and the organizations to which human beings are affiliated or that edit publications). the figure also includes the creation class (e.g., a paper or a book chapter). finally, figure 6 has the part of the ontology that describes the different events that occur in the process of publishing a paper (i.e., paper submission, paper acceptance, notification of future publication, and publication). figure 1. example rdf graph semantic web for reliable citation analysis in scholarly publishing | tous, guerrero, and delgado 29 cryptography. the necessary changes do not apply only to the citation-management software, but also to all the involved parties in the publishing lifecycle (e.g., conference and journal management systems). authors and publishers would be the originators of the digitally signed evidences, thus user-friendly tools for generating and signing the rdf metadata would be required. plenty of rdf editors and digital signature toolkits exist, but we predict that conference and journal management systems such as edas could easily be extended to provide integrated functionalities for generating and processing digitally signed metadata graphs. this could be transparent to the users because the rdf documents would be automatically generated (and also signed in the case of the publishers) during the creating–editing– publishing process. because our approach is based on a pki trust scheme, we rely on a special setup assumption: the existence of cas, which certify that the identity information and the public key contained within the public key certificates of authors and publishers belong together. to get a publication recognized by a reliable citation-analysis system, an author or a publisher would need a public-key certificate issued by a ca trusted by this citation-analysis system. the selection of trusted ■■ an author can certify to any evaluation entity that will evaluate his or her curriculum the publications that he or she has done. ■■ an evaluator entity can query the citation-analysis system and get all the publications that a certain author has done. ■■ an author cannot forge notifications of publication. ■■ a publisher cannot repudiate the fact that it has published an article once it has sent the certificate. ■■ two or more authors cannot team up and make the system think that they are the same person to have more

changes but also in terms of behavioral changes at some of the stages of the scholarly publishing workflow. regarding the technological impact, the approach relies on the use of semantic web technologies and public-key <rdf:rdf xmlns:rdf= “http://www.w3.org/1999/02/22-rdf-syntax-ns#” xmlns:ex= “http://example.org/vocab#”> <ex:submitted rdf:id=

citation-analysis system obtains the information or whether the information is duplicated. the proposed approach guarantees that the citation-analysis subsystem can always verify the provenance and trust of the metadata, and the use of unique identifiers ensures the detection of duplicates. our approach also implies minor behavioral changes for authors, mainly related to the management of publickey certificates, which is often required for many other tasks nowadays. a collateral benefit of the approach would be the automation of the copyright transfer procedure, which in most cases still relies on handwritten signatures. authors would only be required to have their public-key certificate at hand (probably installed in the web browser), and the conference and journal management software would do all the work. cas by citation-analysis systems would require the deployment of the necessary mechanisms to allow an author or a publisher to ask for the inclusion of his or her institution in the list. however, this process would be eased if some institutional cas belonged to trust hierarchies (e.g., national or regional), so including some higher-level cas makes the inclusion of cas of some small institutions easier. another technological implication is related to the interchange and storage of the metadata. users and publishers should save the signed metadata coming from a publishing process digitally, and citation-analysis systems should harvest the digitally signed metadata. the metadata-harvesting process could be done in several different ways; but here raises an important benefit of the presented approach: the fact that it does not matter where figure 5. part of the ontology describing agents and creations 32 information technology and libraries | march 2011 domain, but which we have taken in consideration. in our approach, static and dynamic metadata cross many trust boundaries, so it is necessary to apply trust management techniques designed to protect open and decentralized systems. we have chosen a public-key infrastructure (pki) design to cover such a requirement. however, other approaches exist, such as the one by khare and rifkin, which combines rdf with digital signatures in a manner related to what is known as the “web of trust.”13 one aspect of any approach dealing with rdf and cryptography is how to digitally sign rdf graphs. as described above, in the section “modeling the scholarly communication process with semantic web knowledge representation techniques,” there are two different approaches for such a task, signing the file from which the graph will be obtained (which is the one we have chosen) or digitally signing the graphs themselves (the information represented in them), as described by carroll.14 ■■ conclusions the work presented in this paper describes a reference architecture that aims to provide reliability to the citation and citation-tracking lifecycle. the paper defends that current practices in the analysis of impact of scholarly artifacts entail serious design and security flaws, including nonidentical instances confusion, author-naming conflicts, fake citing, repudiation, impersonation, etc. ■■ related work as far as we know, this is the first paper to combine semantic web technologies and public-key cryptography to achieve reliable citation analysis in scholarly publishing. regarding the use of ontologies and semantic web technologies for modeling the scholarly domain, we highlight the research by rodriguez, bollen, and van de sompel.12 they define a semantic model for the scholarly communication process, which is used within an associated large-scale semantic store containing bibliographic, citation, and use data. this work is related to the mesur (metrics from scholarly usage of resources) project (http://www.mesur.org) from los alamos national laboratory. the project’s main goal is providing novel mechanisms for assessing the impact of scholarly communication items, and hence of scholars, with metrics derived from use data. as in our case, the approach by rodriguez, bollen, and van de sompel models static and dynamic aspects of the scholarly communication process using rdf and owl. however, contrary to what happens in that approach, our work focuses on modeling the dynamic aspects of the creation–editing–publishing workflow, while the approach by rodriguez, bollen, and van de sompel focuses on modeling the use of alreadypublished bibliographic resources. regarding the combination of semantic web technologies with security aspects and cryptography, there exist several works that do not specifically focus in the scholarly figure 6. part of the ontology describing events semantic web for reliable citation analysis in

scholarly communication process with rdf graphs, we have designed an owl dl ontology. rdf graphs carrying instances of classes and properties from the ontology will be digitally signed and interchanged between parties at the different stages of the creation–editing–publishing process. citation-management systems will have access to these signed metadata graphs and will be able to verify their provenance and trust before incorporating them to their repositories. because citation analysis has become a critical component in scholarly impact factor calculation, and considering the relevance of this metric within the scholarly publishing value chain, we defend that the relevance of providing a reliable solution justifies the effort of introducing technological changes within the publishing lifecycle. we believe that these changes, which could be easily automated and incorporated to the modern conference and journal editorial systems, are justified considering the serious flaws of the established solutions and the relevance that citation-analysis systems are acquiring in our society ■■ acknowledgment this work has been partly supported by the spanish administration

in july 1966, the library and information technology association (lita) was officially born at the american library association (ala) annual conference in new york as the information science and automation division (isad). it was bastille day, and i’m sure for those who had worked so hard to create this new organization that it probably seemed like a revolution, a new day. the organizational meeting held that day attracted “several hundred people.” imagine! i’ve mentioned it before, i know, but the history of the first twenty-five years of lita is intriguing reading and well worth an investment of your time. stephen r. salmon’s article “lita’s first twenty-five years: a brief history” (www.lita.org/ala/lita/aboutlita/org/1st 25years.htm) offers an interesting look back in time. any technology organization that has been in existence for forty or more years has seen a lot of changes and adapted over time to a new environment and new technologies. there is no other choice. someone (who, i don’t remember; i’d gladly attribute the quote if i did) once told me that library automation began with the electric eraser. i’m sure that many of you have neither seen an electric eraser, nor can you probably imagine its purpose. ask around. i’m sure there are staff in your organization who do remember using it. there may even be one hidden somewhere in your library. a quick search of the web even finds cordless, rechargeable electric erasers today in drafting and art supply stores. the 1960s, as lita was born, was still the era of the big mainframe systems and not-so-common programming languages. machine readable cataloging (marc) was born and oclc conceived. the 1970s saw the introduction of minicomputer systems. digital equipment corporation introduced the vax, a 32-bit platform, in 1976. the roots of many of our current integrated library systems reach back to this decade. the 1980s saw the introduction of the ibm personal computer and the apple macintosh. the graphical interface became the norm or at least the one to imitate. the 1990s saw a shift away from hardware to communication and access as the web was unveiled and began to give life to the internet bubble. the new millennium began with y2k. the web predominates, and increasingly, the digital form dominates almost everything we touch (text, audio, video). automation and systems evolved and changed over the years, and so did libraries. automation, which had been confined to large air-conditioned and monitored rooms, moved out into the library. it increasingly appeared at circulation desks, on staff desks, and then throughout the library. information technology (it) spread into offices everywhere and into homes. libraries had products and services to deliver to users. users demanded more convenience. of course, others knew this trend as well and provided products and services that users wanted. users often liked what they saw in stores better than what the library was able to provide. each of us attempts to keep up, compete, and beat those whom we see as our competitors. it’s a moving target and one that seems to be gaining speed. all the while, during these four decades, our association and its members continually adapted to the new environment, faced new challenges, and adopted new technologies. we would not exist if we did not. i feel that we, as an association, are again facing the need to change, to transform ourselves. it, digital technology, automation (whatever term you want to use) affects the work of virtually every library staff member. everyone’s work in the library uses or contributes to the digital presence of our employer. it is not the domain of a few. lita has a wonderful history and it has great potential to better serve the profession. what do we want our association to be? what programs and services can we provide that others do not? who can we involve to broaden our reach? how can we better communicate with members and nonmembers? if we had a clean sheet of paper, what would we write? what would we dream? we need to share that dream and bring it to life. i can’t do it. the lita board can’t do it. we need your help. we need your ideas. we need your energy. we need to break out of our comfort zone. none of us wants the strategic plan (www.lita.org/ala/lita/aboutlita/org/plan.htm) we adopted last year to ring hollow. we want to accelerate change and move into a reenergized future. i welcome your aspirations, ideas, and comments. i know that the lita board does as well. please feel free to contact me or any member of the board (www.lita .org/ala/lita/aboutlita/org/litagov/board.htm). lita is your association. where should we be going? help us navigate the future. patrick mullin patrick mullin

president's message: sustaining lita lita president’s message sustaining lita emily morton-owens information technology and libraries | september 2019 2 emily morton-owens (egmowens.lita@gmail.com) is lita president 2019-20 and the assistant university librarian for digital library development & systems at the university of pennsylvania libraries. recently, at the 2019 midwinter meeting in seattle, ala decided to adopt sustainability as one of the core values of librarianship. the resolution includes the idea of a triple bottom line: “to be truly sustainable, an organization or community must embody practices that are environmentally sound and economically feasible and socially equitable.” if you had thought of sustainability mainly in terms of the environment, you have plenty of company. i originally pictured it as an umbrella term for a variety of environmental efforts: clean air, waste reduction, energy efficiency. but in fact the idea encompasses human development in a broader sense. one definition of sustainability involves making decisions in the present that take into account the needs of the future. of course our current environmental threats demand our attention, and libraries have found creative ways to promote environmental consciousness (myriad examples include books on bikes, seeking leed or passive house certification for library buildings, providing resources on xeriscaping, and many more). even if you’re not presently working in a position that allows you to engage directly on the environment, though, the concept of sustainability turns out to permeate our work and values. the ideas of solving problems in a way that doesn’t create new challenges for future people, developing society in a way that allows all people to flourish, and fostering strong institutions: these concepts all resonate with the work we do daily, not only in what we offer our users but also in how we work with each other. as a profession, we have a history of designing future-proof systems (or at least attempting to). whenever i’ve been involved in planning a digital library project, one of the first questions on the table is “how do we get our data back out of this, when the time comes?” no matter how enamored we are of the current exciting new solution, we remember that things will look different in the future. library metadata schemas are all about designing for interoperability and reusability, including in new ways that we can’t picture yet. someone who is unaccustomed to this kind of planning may see a high project overhead for these concerns, but we have consistently incorporated long-term thinking into our professional values due to the importance we place on free access, data preservation, and interoperability. the triple-bottom line approach, considering economic, social, and environmental factors, also influences the lita leadership. i recently announced the lita board’s decision to reduce our in person participation at ala midwinter for 2020, which is partly in response to ala’s deliberations about reinventing the event starting in 2021. with all the useful collaboration technologies now at our fingertips, it is harder to justify requiring our members to meet in person more than once per year. it is possible for us to do great work, on a continuous and rolling basis, throughout the year. more importantly, we want to offer committee and leadership positions to members who may not mailto:egmowens.lita@gmail.com

(especially when many do not receive financial support from their employers. and, to come back around to environmental concerns for a moment, think of all the flights our in-person meetings require.) by being more flexible about what participation looks like, we sustain the effort that our members put into lita through a world of work that is changing. financial sustainability is also a factor in our pursuit of a merger with alcts and llama. we are three smaller divisions based on professional role, not library type, who share interests and members. we also have similar needs and processes for running our respective associations. unfortunately, lita has been on an unsustainable course with our budget for some time—we spend more than we take in annually, due to overhead costs and working within ala’s processes and infrastructure. the lita board has engaged for many years on the question of how to balance our financial future with the fact that our programs require full-time staff, instructors, technology, printing, meeting rooms, etc. core, as the new merged division will be known, will allow us to correct that balance by combining our operations, streamlining workflows, and containing our costs. the staff will also be freed up to invest more effort in member engagement. we can’t predict all the services that associations will offer in the future, but we know that, for example, online professional development is always needed, so we’re ensuring that the plan allows it to continue. it is inspiring to talk about the new collaborations and subject-matter synergies that the merger will bring with it, but core will also achieve something important for sustaining a level of service to our membership. at the ala level, the steering committee on organizational effectiveness (scoe) is also looking at ways to streamline the association’s structure and make it more approachable and welcoming to new members. i would add that a simplified structure should make ala more accountable to members as well, which is crucial for positioning it as an organization worth devoting yourself to. these shifts are essential because member volunteers are what make ala happen, and we need a structure that invites participation from future generations of library workers. taken together, these may look like a confusing flurry of changes. but librarians have evolved to be excellent at long-term thinking about our goals and values and how to pursue an exciting future vision based on what we know now and what tools (technology, people, ideas) we have at hand. we care about helping our users thrive and are able to take a broad view of what that encompasses. in particular, with the new resolution about sustainability, we’re including the health of our communities and the security of our environment as a part of that mission. due to their innovative spirit and principled sense of commitment, our members are well-placed to lead transformations in their home institutions and to participate in the development of lita. as we weigh all these changes, we value the achievements of our association and its past leaders and members, and seek to honor them by making sure those successes carry on for our future colleagues. september_ital_yelton_final president’s message: 50 years andromeda yelton information technologies and libraries | september 2017 1 fifty years. lita was voted into existence (as isad, the information science and automation division) in detroit at midwinter 1966. therefore we have just completed our first fifty years, a fact celebrated (thanks to our 50th anniversary task force) with a slide show and cake at annual in chicago. it’s truly humbling to take office upon this milestone. looking back, some of the true giants of library technology have held this office. in 1971-72, jesse shera, who in his wide-ranging career challenged librarians to think deeply about the epistemological and sociological dimensions of librarianship; ala makes several awards in his name today. in 1973-74 and again in 1974-75, frederick kilgour, the founding director of oclc, who also has an eponymous award. in 1975-76, henriette avram, the mother of marc, herself. moreover, thanks to the work of countless lita volunteers, much of this history is available openaccess. i strongly recommend reading http://www.ala.org/lita/about/history/ for an overview of the remarkable people and key issues across our history. you can also read papers by avram and kilgour, among many others, in the archives of this very publication. in fact, reading the ital archives is deeply engaging. it turns out library technology has changed a bit in 50 years! (i trust that isn’t a shock to you.) the first articles (in what was then the journal of library automation) are all about instituting first-time computer systems to automate traditional library functions such as acquisitions, cataloging, and finance. the following passage caught my eye: “a functioning technical processing system in a two-year community college library utilizes a model 2201 friden flexowriter with punch card control and tab card reading units, an ibm 026 key punch, and an ibm 1440 computer, with two tape and two disc drives, to produce all acquisitions and catalog files based primarily on a single typing at the time of initiating an order” (“an integrated computer based technical processing system in a small college library”, jack w. scott; https://doi.org/10.6017/ital.v1i3.2931.) how many of us are still using punch cards today? and, indeed, how many of us are automating libraries for the first time? the topics discussed among lita members today are far more wideranging: user experience, privacy, accessibility. they’re more likely to be about assessing and improving existing systems than creating new ones, and more likely to center on patron-facing technologies. andromeda yelton (andromeda.yelton@gmail.com) is lita president 2017-18 and owner/consultant of small beautiful useful llc. president’s message | yelton https://doi.org/10.6017/ital.v36i3.10086 2 and yet, with a few substitutions — say, “raspberry pi” for “friden flexowriter” — the blockquote above would not be out of place today. then as now, lita members were doing something exciting, yet deeply practical, that cleverly repurposes new technology to make library experiences better for both patrons and staff. our job descriptions have changed enormously in fifty years; in fact, the lita board charged a task force to develop lita member personas, so that we can better understand whom we serve, and work to align our publications, online education, conference programming, and committee work toward your needs. (you can see an overview of the task force’s stellar work on litablog: http://litablog.org/2017/03/who-are-lita-members-lita-personas/.) at the same time, the spirit of pragmatic creativity that runs throughout the first issues of the journal of library automation continues to animate lita members today. i’m looking forward to seeing where we go in our next fifty years. 26 information technology and libraries | september 2007 author id box for 2 column layout wikis in libraries matthew m. bejune wikis have recently been adopted to support a variety of collaborative activities within libraries. this article and its companion wiki, librarywikis (http://librarywikis. pbwiki.com/), seek to document the phenomenon of wikis in libraries. this subject is considered within the framework of computer-supported cooperative work (cscw). the author identified thirty-three library wikis and developed a classification schema with four categories: (1) collaboration among libraries (45.7 percent); (2) collaboration among library staff (31.4 percent); (3) collaboration among library staff and patrons (14.3 percent); and (4) collaboration among patrons (8.6 percent). examples of library wikis are presented within the article, as is a discussion for why wikis are primarily utilized within categories i and ii and not within categories iii and iv. it is clear that wikis have great utility within libraries, and the author urges further application of wikis in libraries. i n recent years, the popularity of wikis has skyrocketed. wikis were invented in the mid­1990s to help facilitate the exchange of ideas between computer programmers. the use of wikis has gone far beyond the domain of com­ puter programming, and now it seems as if every google search contains a wikipedia entry. wikis have entered into the public consciousness. so, too, have wikis entered into the domain of professional library practice. the purpose of this research is to document how wikis are used in librar­ ies. in conjunction with this article, the author has created librarywikis (http://librarywikis.pbwiki.com/), a wiki to which readers can submit additional examples of wikis used in libraries. the article will proceed in three sections. the first section is a literature review that defines wikis and introduces computer­supported cooperative work (cscw) as a context for understanding wikis. the second section documents the author’s research and presents a schema for classifying wikis used in libraries. the third section considers the implications of the research results. ■ literature review what’s a wiki? wikipedia (2007a) defines a wiki as: a type of web site that allows the visitors to add, remove, edit, and change some content, typically with­ out the need for registration. it also allows for linking among any number of pages. this ease of interaction and operation makes a wiki an effective tool for mass collaborative authoring. wikis have been around since the mid­1990s, though it is only recently that they have become ubiquitous. in 1995, ward cunningham launched the first wiki, wikiwikiweb (http://c2.com/cgi/wiki), which is still active today, to facilitate the exchange of ideas among computer program­ mers (wikipedia 2007b). the launch of wikiwikiweb was a departure from the existing model of web communica­ tion ,where there was a clear divide between authors and readers. wikiwikiweb elevated the status of readers, if they so chose, to that of content writers and editors. this model proved popular, and the wiki technology used on wikiwikiweb was soon ported to other online communi­ ties, the most famous example being wikipedia. on january 15, 2001, wikipedia was launched by larry sanger and jimmy wales as a complementary project for the now­defunct nupedia encyclopedia. nupedia was a free, online encyclopedia with articles written by experts and reviewed by editors. wikipedia was designed as a feeder project to solicit new articles for nupedia that were not submitted by experts. the two services coexisted for some time, but in 2003 the nupedia servers were shut down. since its launch, wikipedia has undergone rapid growth. at the close of 2001, wikipedia’s first year of operation, there were 20,000 articles in eighteen language editions. as of this writing, there are approximately seven million articles in 251 languages, fourteen of which have more than 100,000 articles each. as a sign of wikipedia’s growth, when this manuscript was first submitted four months earlier, there were more than five million articles in 250 languages. author’s note: sources in the previous two para­ graphs come from wikipedia. the author acknowledges the concerns within the academy regarding the practice of citing wikipedia within scholarly works; however, it was decided that wikipedia is arguably an authoritative source on wikis and itself. nevertheless, the author notes that there were changes—insubstantial ones—to the cited wikipedia entries between when the manuscript was first submitted and when it was revised four months later. wikis and cscw wikis facilitate collaborative authoring and can be con­ sidered one of the technologies studied under the domain of cscw. in this section, cscw is explained and it is shown how wikis fit within this framework. cscw is an area of computer science research that considers the application of computer technology to sup­ port cooperative, also referred to as collaborative work. the term was first coined in 1984 by irene greif (1988) and matthew m. bejune (mbejune@purdue.edu) is an assistant professor of library science at purdue university libraries. he also is a doctoral student at the graduate school of library and information science, university of illinois at urbana-champaign. article title | author 27wikis in libraries | bejune 27 paul cashman to describe a workshop they were planning on the support of people in work environments with com­ puters. over the years there have been a number of review articles that describe cscw in greater detail, including bannon and schmidt (1991), rodden (1991), schmidt and bannon (1992), sachs (1995), dourish (2001), ackerman (2002), olson and olson (2002), dix, finlay, abowd, and beale (2004), and shneiderman and plaisant (2005). publication in the field of cscw primarily occurs through conferences. the first conference on cscw was held in 1986 in austin, texas. since then, the conference has been held biennially in the united states. proceedings are published by the association for computing machinery (acm, http://www.acm.org/). in 1991, the first european conference on computer supported cooperative work (ecscw) was held in amsterdam. ecscw also is held biennially, in odd­numbered years. ecscw proceedings are published by springer (http://www.ecscw.uni­sie­ gen.de/). the primary journal for cscw is computer supported cooperative work: the journal of collaborative computing. publications also appear within publications of the acm and chi, the conference on human factors in computing. cscw and libraries as libraries are, by nature, collaborative work envi­ ronments—library staff working together and with patrons—and as digital libraries and computer technolo­ gies become increasingly prevalent, there is a natural fit between cscw and libraries. the following researchers have applied cscw to libraries. twidale et al. (1997) pub­ lished a report sponsored by the british library research and innovation centre that examined the role of col­ laboration in the information­searching process to inform how information systems design could better address and support collaborative activity. twidale and nichols (1998) offered ethnographic research of physical collaborative environments—in a university library and an office—to aid the design of digital libraries. they wrote two reviews of cscw as applied to libraries—the first was more com­ prehensive (twidale and nichols 1998) than the second (twidale and nichols 1999). sánchez (2001) discussed collaborative environments designed and prototyped for digital library environments. classification of collaboration technologies that facilitate collaborative work are typically classified within cscw across two continua: synchronous versus asynchronous, and co­located versus remote. if put together in a two­by­two matrix, there are four possibilities: (1) synchronous and co­located (same time, same place); (2) synchronous and remote (same time, different place); (3) asynchronous and remote (different time, different place); and (4) asynchronous and co­located (different time, same place). this classification schema was first proposed by johansen et al. (1988). nichols and twidale (1999) mapped work applications within the realm of cscw in figure 1. wikis are not present in the figure, but their absence is not an indication that they are not cooperative work technologies. rather, wikis were not yet widely in use at the time cscw was considered by nichols and twidale. the author has added wikis to nichols and twidale’s graphical representation in figure 2. interestingly, wikis are border­crossers fitting within two quadrants: the upper right—asynchronous and co­located; and the lower right—asynchronous and remote. wikis are asynchronous in that they do not require people to be working together at the same time. they are both co­located and remote in that people working collaboratively may not need to be working in the same place. it is also interesting to note that library technologies also can be mapped using johansen’s schema. nichols and twidale (1999) also mapped this, and figure 3 illus­ trates the variety of collaborative work that goes on within libraries. ■ method in order to to discover the widest variety of wikis used in libraries, the author searched for examples of wikis used in libraries within three areas—the lis literature, the library success wiki, and within messages posted on three professional electronic discussion lists. when examples were found, they were logged and classified according to a schema created by the author. results are presented in the next section. the first area searched was within the lis literature. the author utilized the wilson library literature and

information science database. there were two main types of articles: ones that argued for the use of wikis in libraries, and ones that were case studies of wikis that had been implemented. the second area searched was within library success: a best practices wiki (http://www.libsuccess.org/) (see figure 4), created by meredith farkas, distance learning librarian at norwich university. as the name implies, it is a place for people within the library community to share their success stories. posting to the wiki is open to the public, though registration is encouraged. there are many subject areas on the wiki, including management and leadership, readers’ advisory, reference services, infor­ mation literacy, and so on. there also is a section about collaborative tools in libraries (http://www.libsuccess .org/index.php?title=collaborative_tools_in_libraries), in which examples of wikis in libraries are presented. within this section there is a presentation about wikis made by farkas (2006) titled wiki world (http://www. libsuccess.org/indexphp?title=wiki_world), from which examples were culled. the third area that was searched was professional electronic discussion list messages from web4lib, dig_ ref, and libref­l. the web4lib electronic discussion list (tennant 2005) is “for the discussion of issues relating to the creation, management, and support of library­ based world wide web servers, services, and applica­ tions.” the list is moderated by roy tennant and the web4lib advisory board and was started in 1994. the dig_ref electronic discussion list is a forum for “people and organizations answering the questions of users via the internet” (webjunction n.d.). the list is hosted by the information institute of syracuse, school of information studies, syracuse university, and was created in 1998. the libref­l electronic discussion list is “a moderated discussion of issues related to reference librarianship (balraj 2005). established in 1990, it’s operated out of kent state university and moderated by a group of list own­ ers. these three electronic discussion lists were selected for two reasons. first, the author is a subscriber to each electronic discussion list, and prior to the research noted there were messages about wikis in libraries. second, based on the descriptions of each electronic discussion list stated above, the selected electronic discussion lists reasonably covered the discussion of wikis in libraries within the professional library electronic discussion lists. one year of messages, november 15, 2005, through november 14, 2006, was analyzed for each list. messages about wikis in libraries were identified through key­ word searches against the author’s personal archive of electronic discussion list messages collected over the figure 2. classification of cscw applications including wikis co-located remote synchronous asynchronous meeting rooms distributed meetings muds and moos shared drawing

libsuccess.org/) article title | author 29wikis in libraries | bejune 29 years. an alternative method would have been to search the web archive of each list, but the author found it easier to search within his mail client, microsoft outlook. messages with the word “wiki” were found in 513 mes­ sages: 354 in web4lib, 91 in dig_ref, and 68 in libref­ l. this approach had high recall, as discourse about wikis frequently included the use of the word “wiki,” though low precision, as there were many results that were not about wikis used in libraries. common false hits included messages about the nature study (giles 2005) that com­ pared wikipedia to encyclopedia britannica, and messages that included the word “wiki” but were simply refer­ ring to wikis, though not examples of wikis used within libraries. from the list of 513 messages, the author read each message and came up with a much shorter list of thirty­nine messages about wikis in libraries: thirty­two in web4lib, three in dig_ref, and four in libref­l. ■ results classification of the results after all wiki examples had been collected, it became clear that there was a way to classify the results. in farkas’s (2006) presentation about wikis, she organized wikis in two categories: (1) how libraries can use wikis with their patrons; and (2) how libraries can use wikis for knowledge sharing and collaboration. this schema, while it accounts for two types of collaboration, is not granular enough to represent the types of collaboration found within the wiki examples identified. as such, it became clear that another schema was needed. twidale and nichols (1998) identified three types of collaboration within libraries: (1) collaboration among library staff; (2) collaboration between a patron and a member of staff; and (3) collaboration among library users. their classification schema mapped well to the examples of wikis that were identified; however, it too was not granular enough, as it did not distinguish among col­ laboration between library staff intraorganizationally and extraorganizationally, the two most common types of wiki usage found in the research (see appendix). to account for these types of collaboration, which are common not only to wiki use in libraries but to all professional library prac­ tice, the author modified twidale and nichols schema (see figure 6). the improved schema also uniformly represents entities across the categories—library staff and member of staff are referred to as “library staff,” and patrons and library users are referred to as “patrons.” examples of wikis used in libraries for each category are provided to better illustrate the proposed classifica­ tion schema. ■ collaboration among libraries the library instruction wiki (http://instructionwiki .org/main_page) is an example of a wiki that is used for collaboration among libraries (figure 7). it appears as though the wiki was originally set up to support library instruction within oregon—it is unclear if this was asso­ ciated with a particular type of library, say academic or public—but now the wiki supports library instruction in general. the wiki is self­described as: a collaboratively developed resource for librarians involved with or interested in instruction. all librarians and others interested in library instruction are welcome and encouraged to contribute. the tagline for the wiki is “stop reinventing the wheel”(library instruction wiki 2006). from this wiki there figure 6. four types of collaboration within libraries 1. collaboration among libraries (extra-organizational) 2. collaboration among library staff (intra-organizational) 3. collaboration among library staff and patrons 4. collaboration among patrons figure 5. wiki world (http://www.libsuccess.org/index.php?title=wiki _world) 30 information technology and libraries | september 200730 information technology and libraries | september 2007 is a list of library instruction resources that include the fol­ lowing: handouts, tutorials, and other resources to share; teaching techniques, tips, and tricks; class­specific web sites and handouts; glossary and encyclopedia; bibliography and suggested reading; and instruction­related projects, brainstorms, and documents. within the handouts, tutori­ als, and other resources to share section, the author found a wide variety of resources from libraries across the country. similarly, there were a number of suggestions to be found under the teaching techniques, tips, and tricks section. another example of a wiki used for collaboration among libraries is the library success wiki (http://www .libsuccess.org/), one of the sources of examples of wikis used in this research. adding to earlier descriptions of this wiki as presented in this paper, library success seems to be one of the most frequently updated library wikis and perhaps the most comprehensive in its cover­ age of library topics. ■ collaboration among library staff the university of connecticut libraries’ staff wiki (http:// wiki.lib.uconn.edu/) is an example of a wiki used for col­ laboration among library staff (figure 8). this wiki is a knowledge base containing more than one thousand infor­ mation technology services (its) documents. its docu­ ments support the information technology needs of the library organization. examples include answers to com­ monly asked questions, user manuals, and instructions for a variety of computer operations. in addition to being a repository of its documents, the wiki also serves as a portal to other wikis within the university of connecticut libraries. there are many other wikis connected to library units; teams; software applications, such as the libraries ils; libraries within the university of connecticut libraries; and other university of connecticut campuses. the health science library knowledge base, stony brook university (http://appdev.hsclib.sunysb.edu/ twiki/bin/view/main/webhome) is another example of a wiki that is used for collaboration among library staff (figure 9). the wiki is described as “a space for the dynamic collaboration of the library staff, and a platform of shared resources” (health sciences library 2007). on the wiki there are the following content areas: news and announcements; hsl departments; projects; trouble­ shooting; staff training resources, working papers and support materials; and community activities, scholarship, conferences, and publications. ■ collaboration among library staff and patrons there are only a few examples of wikis used for collabora­ tion among library staff and patrons to cite as exemplars. one example is the st. joseph county public library (sjpl) subject guides (http://www.libraryforlife.org/ subjectguides/index.php/main_page), seen in figure 10. this wiki is a collection of resources and services in print and electronic formats to assist library patrons with subject area searching. as the wiki is published by library staff for public consumption, it has more of a professional feel than wikis from the first two categories. pages have images, and the content is structured to look like a standard web page. though the wiki looks like a web page, there still remain a number of edit links that follow each section of text on the wiki. while these tags bear importance for those editing figure 7. library instruction wiki (http://instructionwiki.org/) figure �. the university of connecticut libraries’ staff wiki (http:// wiki.lib.uconn.edu/) article title | author 31wikis in libraries | bejune 31 the wiki—library staff only in this case—they undoubtedly puzzle library patrons who think that they have the ability to edit the wiki when, in fact, they do not. another example of collaboration between library staff and patrons that takes a similar approach is the usc aiken gregg­graniteville library web site (http://library. usca.edu/) in figure 11. as with the sjpl subject guides, this wiki looks more like a web site than a wiki. in fact, the usc aiken wiki conceals its true identity as a wiki even more so than the sjpl subject guides. the only evidence that the web site is a wiki is a link at the bottom of each page that says “powered by pmwiki.” pmwiki (http:// pmwiki.org/) is a content management system that uti­ lizes the wiki technology on the back end to manage a web site while retaining the look and feel of a standard web site. it seems that the benefits of using a wiki in such a way are shared content creation and management. ■ collaboration among patrons as there are only three examples of wikis used for col­ laboration among patrons, all examples will be high­ lighted in this section. the first example is wiki worldcat (http://www.oclc.org/productworks/wcwiki.htm), sponsored by oclc. wiki worldcat launched as a pilot project in september 2005. the service allows users of open worldcat, oclc’s web version of worldcat, to add book reviews to item records. though this wiki does not have many book reviews in it, even for contemporary bestsellers, it gives a taste for how a wiki could be used to facilitate collaboration among patrons. a second example is the biz wiki from ohio university libraries (http://www.library.ohiou.edu/subjects/ bizwiki/index.php/main_page) (see figure 12). the biz wiki is a collection of business information resources avail­ able through ohio university. the wiki was created by chad boeninger, reference and instruction librarian, as an alternate form of a subject guide or pathfinder. what separates this wiki from those in the third category, collaboration among library staff and patrons, is that the wiki is editable by patrons as well as librarians. similarly, butler wikiref (http://www .seedwiki.com/wiki/butler_wikiref) is a wiki that has reviews of reference resources created by butler librarians, faculty, staff, and students (see figure 13).figure 9. health sciences library knowledge base (http://appdev .hsclib.sunysb.edu/twiki/bin/view/main/webhome) figure 11. usc aiken gregg-graniteville library (http://library.usca .edu/) figure 10. sjcpl subject guides (http://libraryforlife.org/subject guides/index.php/main_page/) 32 information technology and libraries | september 200732 information technology and libraries | september 2007 full results thirty­three wikis were identified. two wikis were classi­ fied in two categories each. the full results are available in the appendix. table 1 illustrates how wikis were not uniformly distributed across the four categories: category i had 45.7 percent, category ii had 31.4 percent, category iii had 14.3 percent, and category iv had 8.6 percent. nearly 80 percent of all examples were found within categories i and ii. as seen in some of the examples in the previous section, wikis were utilized for a variety of purposes. here is a short list of purposes for which wikis were utilized: for sharing information, supporting association work, collecting soft­ ware documentation, supporting conferences, facilitating librarian­to­faculty collaboration, creating digital reposito­ ries, managing web content, creating intranets, providing reference desk support, creating knowledge bases, creating subject guides, and collecting reader reviews. wiki software utilization is summarized in tables 2 and 3. mediawiki is the most popular software utilized by libraries (33.3 percent), followed by unknown (30.3 percent), pbwiki (12.1 percent), pmwiki (12.1 percent), seedwiki (6.1 percent), twiki (3 percent), and xwiki (3 percent). if the values for unknown are removed from the totals (table 3 ), mediawiki is utilized in almost half (47.8 percent) of all library wiki applications. ■ discussion with a wealth of examples of wikis in categories i and ii and a dearth of examples of wikis in categories iii and iv, the library community seems to be more comfortable using wikis to collaborate within the community, but less comfortable using wikis to collaborate with library patrons or to enable collaboration among patrons. the research results pose the questions: why are wikis pre­ dominantly used for collaboration within the library community? and why are wikis minimally used for col­ laborating with patrons and helping patrons to collabo­ rate with one another? why are wikis predominantly used for collaboration within the library community? this is perhaps the easier of the two questions to explain. there is a long legacy of cooperation and collaboration intraorganizationally and extraorganizationally within libraries. one explanation for this is the shared bud­ getary climate within libraries. all too often there are insufficient money, staff, and resources to offer desired levels of service. librarians work together to overcome these barriers. prominent examples include coopera­ tive cataloging, interlibrary lending, and the formation of consortia to negotiate pricing. another explanation can be found in the personal characteristics of library professionals. librarianship is a service profession that consequently attracts service­minded individuals who are interested in helping others, whether they are library patrons or fellow colleagues. a third reason is the role of library associations, such as the international federation of library associations and institutions, the american library association, the special libraries association, and the medical library association, as well as many others at the international, national, state, and local lev­ figure 12. ohio university libraries biz wiki (http://www.library. ohiou.edu/subjects/bizwiki) figure 13. butler wikiref (http://www.seedwiki.com/wiki/butler_ wikiref) article title | author 33wikis in libraries | bejune 33 els, and the work that is done through these associations at annual conferences and throughout the year. libraries use wikis to collaborate intraorganizationally and extra­ organizationally because collaboration is what they do most naturally. why are wikis minimally used for collaborating with patrons and helping patrons to collaborate with one another? the reasons for why libraries are only minimally using wikis to collaborate with patrons and for patron collabora­ tion are more difficult to ascertain. however, due to the untapped potential of using wikis, the proposed answers to this question are more important and may lead to future implementations of wikis in libraries. here are four pos­ sible explanations, some more speculative than others. first, perhaps one of the reasons is the result of the way in which libraries are conceived by library patrons and librarians alike. a strong case can be made for libraries as places of collaborative work, and the author takes this posi­ tion. however, historically libraries have been repositories of information, and this remains a pervasive and difficult concept to change—libraries are frequently seen simply as places to get books. in this scenario, the librarian is a gate­ keeper that a patron interacts with to get a book—that is, if the patron interacts with a librarian at all. it also is worthy to note that the relationship is one­way—the patron needs the assistance of librarian, but not the other way around. viewed in these terms, this is not a collaborative situation. for libraries to use wikis for the purpose of collaborating with library patrons, it might demand the reconceptualiza­ tion of libraries by library patrons and librarians. similarly, this extreme conceptualization of libraries does not con­ sider patrons working with one another, even though it is an activity that occurs formally and informally within libraries, not to mention with the emergence of interdisci­ plinary and multidisciplinary work. if wikis are to be used to facilitate collaboration between patrons, the conceptual­ ization of the library by library patrons and librarians must be expanded. second, there may be fears within the library commu­ nity about authority, responsibility, and liability. libraries have long held the responsibility of ensuring the authority of the bibliographic catalog. if patrons are allowed to edit the library wiki, there is potential for negatively affecting the authority of the wiki and even the perceived author­ ity of the library. likewise, there is potential liability in allowing patrons to post to the library wiki. similar con­ table 2. software totals

september 20073� information technology and libraries | september 2007 cerns have been raised in the past about other collabora­ tive technologies, such as blogs, bulletin boards, mailing lists, and so on, all aspects of the library 2.0 movement. if libraries are fully to realize library 2.0 as described by casey and savastinuk (2006), miller (2006), and courtney (2007), these issues must be considered. third, perhaps it is due to a matter of fit. it might be the case that wikis are utilized in categories i and ii and not within categories iii and iv because the tools are better suited to support the types of activities within categories i and ii. consider some of the activities listed earlier: sup­ porting association work, collecting software documenta­ tion, supporting conferences, creating digital repositories, creating intranets, and creating knowledge bases. each of these illustrates a wiki that is utilized for the creation of a resource with multiple authors and readers, tasks that are well­suited to wikis. wikipedia is a great example of a wiki with clear, shared tasks for multiple authors and multiple readers and a sense of persistence over time. in contrast, relationships between library staff and patrons do not typically lead to the shared creation of resources. while it is true that the relationship between patron and librarian in the context of a patron’s research assignment can be collab­ orative depending on the circumstances, authorship is not shared but is possessed by the patron. in addition, research assignments in the context of undergraduate coursework are short­lived and seldom go beyond the confines of a particular course. in terms of patrons working together with other patrons, there is the precedent of group work; however, groups often produce projects or papers that share the characteristics of nongroup research assignments listed above. this, of course, does not mean that wikis are not suitable for collaboration within categories iii and iv, but perhaps the opportunities for collaboration are fewer or that they stretch the imagination of the types and ways of doing collaborative work. fourth, perhaps it is a matter of “not yet.” while the research has shown that libraries are not utilizing wikis in categories iii and iv, this may be because it is too soon. it should be noted that wikis are still new technologies. it might be the case that librarians are experimenting in safer contexts so they will gain experience prior to trying more public projects where their expertise will be needed. if this explanation is true, it is expected that more exam­ ples of wikis in libraries will soon emerge. as they do, the author hopes that all examples of wikis in libraries, new and old, will be added to the companion wiki to this article, librarywikis (http://librarywikis.pbwiki.com/). ■ conclusion it appears that wikis are here to stay, and that their utili­ zation within libraries is only just beginning. this article documented the current practice of wikis used in libraries using cscw as a framework for discussion. the author located examples of wikis in three places: within the lis lit­ erature, on the library success wiki, and within messages from three professional electronic discussion lists. thirty­ three examples of wikis were identified and classified using a classification schema created by the author. the schema has four categories: (1) collaboration among librar­ ies; (2) collaboration among library staff; (3) collaboration among library staff and patrons; and (4) collaboration among patrons. wikis were used for a variety of purposes, including for sharing information, supporting associa­ tion work, collecting software documentation, supporting conferences, facilitating librarian­to­faculty collaboration, creating digital repositories, managing web content, creat­ ing intranets, providing reference desk support, creating knowledge bases, creating subject guides, and collecting reader reviews. by and large, wikis were primarily used to support collaboration among library staff intraorganiza­ tionally and extraorganizationally, with nearly 80 percent (45.7 percent and 31.4 percent respectively) of the examples so identified, and less so in the support of collaboration among library staff and patrons (14.3 percent) and col­ laboration among patrons (8.6 percent). a majority of the examples of wikis utilized the mediawiki software (47.8 percent). it is clear that there are plenty of examples of wikis utilized in libraries, and more to be found each day. it is at this time that the profession is faced with extending the use of this technology, and it is to the future to see how wikis will continue to be used within libraries. works cited ackerman, mark s. 2002. the intellectual challenge of cscw: the gap between social requirements and technical feasibil­ ity. in human-computer interaction in the new

design and library websites mark cyzyk information technology and libraries | march 2018 4 mark cyzyk (mcyzyk@jhu.edu), a member of lita and the ital editorial board, is the scholarly communication architect in the sheridan libraries, the johns hopkins university, baltimore, maryland. our library website has now gone through two major redesigns in the past five or so years. in both cases, a user centered design approach was used to plan the site. in contrast to the single person vision and design by committee approaches, user centered design focuses on the empirical study and eliciting of the needs of users. great attention is paid to studying them, listening to them, and to exposing their needs as expressed. in both of our cases, the overall design, functionality, and content of the new site was then focused exclusively on the results of such study. if a proposed design element, a bit of functionality, or a chunk of content did not appear as an expressly desired feat ure for our users, it was considered clutter and did not make it onto the site. both iterations of our website redesign were strictly governed by this principle. but user centered design has blind spots. first, it may well be that what you take to be your comprehensive user base is not as comprehensive as you think. in my library, our primary users are our faculty and student researchers, so great attention was paid to them. this makes sense insofar as we are an academic library within a major research univ ersity. faculty and student researchers will always be our primary user group. but they are not our comprehensive user group. we have staff, administrators, visitors, members of our board of trustees, members of our friends, outside members of the profession, etc. — and they are all important constituencies in their own ways. second, unless your sample size of users is large enough to be statistically valid, you are merely playing a game of three blind men and the elephant. each user individually will be ex pressing his or her own experience and perceived needs based on that experience, and yet none of them, even taken as a group, will be reporting on the whole beast. while personal testimony definitely counts as evidence, it also frequently and insidiously results in blind spots that would otherwise be exposed through having a statistically valid sample of study participants. third, and perhaps most importantly, user centered design discounts the expertise of librarians. nobody knows a library’s users and patrons as well as librarians. knowing their users, eliciting their needs, is part of what librarians as one of the “helping professions” do; it is a central tenet of librarianship. there is no substitute for experience and the expertise that follows from it. in the art world, this is connoisseurship. somehow, the art historian just knows that what is before him is not a genuine rembrandt. the empirical evidence may ineluctably lead to a different conclusion — yet there remains something missing, something the connoisseur cannot fully elucidate. similarly, in the medical world the radiologist somehow just knows that the subtle gradations on his screen indicate one type of malady and not another. interestingly, in the poultry industry there is something called a “chicken sexer.” this is a person who quickly and accurately sorts baby chicks by sex. training for this vocation mailto:mcyzyk@jhu.edu editorial board thoughts: halfway home | cyzyk 5 https://doi.org/10.6017/ital.v37i1.103813 largely employs what the philosophers call “ostensive definition:” “this one is male; that one is female.” the differences are so small as to be imperceptible. and yet, experienced chicken sexers can accurately sort chicks at an astonishing rate. they just know through experience. such is the nature of tacit knowledge. in the case of our most recent website redesign, none of our users expressed any interest whatsoever, for example, in including floor maps as part of the new site. we were assured a demand for floor maps on the site was “not a thing.” so floor maps were initially excluded from the site. this was met with a slow crescendo of grumbling from the librarians, and rightly so. librarians, and the graduate students at our information desk, know through long experience that researchers of varying types find floor maps of the building to be useful. that’s why we’ve handed out paper copies for years. the fact that this need was missed through our focus on user centered design points to a blind spot in that process. valuable experience and the expertise that follows from it should not be dismissed or otherwise diminished through dogmatic adherence to the core principle of user centered design. ... and yet, don’t get me wrong: insofar as it’s the empirical study of select user groups and their expressed concerns and needs, user centered design as a design technique and foundational principle is crucially important and useful. it gets us halfway home. ital_24n4p3 ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀ ฀

technology brief is to familiarize library decision-makers with the opportunities and challenges of participatory networks. in order to accomplish this goal the brief is divided into four sections (excluding an overview and a detailed statement of goal): ■ a conceptual framework for understanding and evaluating participatory networks; ■ a discussion of key concepts and technologies in participatory networks drawn primarily from web 2.0 and library 2.0; ■ a merging of the conceptual framework with the technological discussion to present a roadmap for library systems development; and ■ a set of recommendations to foster greater discussion and action on the topic of participatory networks and, more broadly, participatory librarianship. this summary will highlight the discussions in each of these four topics. for consistency, the section numbers and titles from the full brief are used. k nowledge is created through conversation. libraries are in the knowledge business. therefore, libraries are in the conversation business. some of those conversations span millennia, while others only span a few seconds. some of these conversations happen in real time. in some conversations, there is a broadcast of ideas from one author to multiple audiences. some conversa­ tions are sparked by a book, a video, or a web page. some of these conversations are as trivial as directing someone to the bathroom. other conversations center on the foun­ dations of ourselves and our humanity. it may be odd to start a technology brief with such seemingly abstract comments. yet, without this firm, if theoretical, footing, the advent of web 2.0, social net­ working, library 2.0, and participatory networks seems a clutter of new terminology, tools, and acronyms. in fact, as will be discussed, without this conceptual footing, many library functions can seem disconnected, and the field that serves lawyers, doctors, single mothers, and eight­year olds (among others) fragmented. the scale of this technology brief is limited; it is to present library decision­makers with the opportunities and challenges of participatory networks. it is only a single piece of a much larger puzzle that seeks to pres­ ent a cohesive framework for libraries. this framework not only will fit tools such as blogs and wikis into their offerings (where appropriate), but also will show how a more participatory, conversational approach to libraries in general can help libraries better integrate current and future functions. think of this document as an overview or introduction to participatory librarianship. readers will find plenty of examples and definitions of web 2.0 and social networking later in this article. however, to jump right into the technology without a larger frame­ work invites the rightful skepticism of a library organiza­ tion that feels constantly buffeted by new technological advances. in any environment with no larger conceptual founding, to measure the importance of an advance in technology or practice selection of any one technology or practice is nearly arbitrary. without a framework, the field becomes open to the influence of personalities and trendy technology. therefore, it is vital to ground any technological, social, or policy conversation into a larger, rooted concept. as susser said, “to practice without theory is to sail an uncharted sea; theory without practice is not to set sail at all.”1 for this paper, the chart will be conversation theory. the core of this article is in four sections: ■ a conceptual framework for understanding and eval­ uating participatory networks; ■ a discussion of key concepts and technologies in par­ ticipatory networks drawn primarily from web 2.0 and library 2.0; ■ a merging of the conceptual framework with the technological discussion to present a sort of roadmap for library systems development; and ■ a set of recommendations to foster greater discussion and action on the topic of participatory networks and, more broadly, participatory librarianship. it is recommended that the reader follow this order to get the big picture; however, the second section should be a useful primer on the language and concepts of partici­ patory networks. ■ library as a facilitator of conversation let us return to the concept that knowledge is created through conversation. this notion stretches back to socrates and the socratic method. however, the specific foundation for this statement comes from conversation theory, a means of explaining cognition and how people learn.2 it is not the purpose of this article to provide a r. david lankes (jdlankes@iis.syr.edu) is director and associate professor, joanne silverstein (jlsilver@iis.syr.edu) is research professor, and scott nicholson (scott@scottnicholson.com) is

silverstein, and scott nicholson 18 information technology and libraries | december 200718 information technology and libraries | december 2007 detailed description of conversation theory, a task already admirably accomplished by pask. rather, let us use the theory as a structure upon which to hang an exploration of participatory networking and, more broadly, participa­ tory librarianship. the core of conversation theory is simple: people learn through conversation. different communities have different standards for conversations, from the scientific community’s rigorous formalisms, to the religious com­ munity’s embedded meaning in scripture, to the some­ times impenetrable dialect of teens. the point remains, however, that different actors establish meaning through determining common definitions and building upon shared concepts. the library has been a place where we facilitate con­ versations, though often implicitly. the concept of learn­ ing through conversation is evidenced in libraries in such large initiatives as information literacy and teaching criti­ cal thinking skills (using such meta­cognitive approaches as self­questioning), and in the smaller events of book groups, reference interviews, and speaker series. library activities such as building collections of artifacts (the tan­ gible products of conversation) inform scholars’ research through a formal conversation process where ideas are supported with evidence and methods. similarly, pres­ ervation efforts, perhaps of wax cylinders with spoken word content or of ancient maps that embody an ongo­ ing dialogue about the shape and nature of the physical world, seek to save, or at least document, important conversations. common use of the word “conversation” is com­ pletely in accordance with the use of the term in conver­ sation theory. the term is, however, more specifically defined as an act of communication and agreement between a set of agents. so, a conversation can be between two people, two organizations, two countries, or even within an individual. how can a conversation take place within an individual? educators and school librarians may be familiar with the term “metacogni­ tion,” or the act of reflecting on one’s learning.3 yet, even the most casual reader will be familiar with the concept of debating oneself (“if i go right, i’ll get there faster, but if i go left i can stop by jim’s . . .”). the point is that a conversation is with at least two agents trying to come to an understanding. also note that those two agents can change over time. so, while socrates and plato are dead, the conversation they started about the nature of knowl­ edge and the world is carried forward by new genera­ tions of thinkers—same conversation, different agents. people converse, organizations converse, states con­ verse, societies converse. the requirements, in the terms of conversation theory, are two cognitive systems seek­ ing agreement. the results of these conversations, what pask would call “cognitive entanglements,” are books, videos, and artifacts that either document, expand, or result from conversations.4 so, while one cannot con­ verse with a book, that book certainly can be a starting point for many conversations within the reader and within a larger community. if the theory is that conversation creates knowledge, the library community has added a corollary: the best knowl­ edge comes from an optimal information environment, one in which the most diverse and complete information is available to the conversant(s). library ethics show an implicit understanding of this corollary in the advocacy of intellectual freedom and unfettered access. libraries seek to create rich environments for knowledge and have taken the stance that they are not in the job of arbitrating the conversations that occur or the appropriateness of the information used to inform those conversations. as will be discussed later, this belief in openness of conversations will have some far­reaching implications for the library collec­ tion and is an ideal that can never truly be met. for now, the reader may take away that conversation theory is very much in line with current and past library practice, and it also shows a clear trajectory for the future. this viewpoint’s value is not just theoretical; it has real consequences and uses. for example, much of library evaluation has been based on numeric counts of tangible outputs: books circulated, collection size, reference transactions, and so on. yet this quantitative approach has been frustrating to many who feel they are count­ ing outcomes but not getting at true impact of library service. librarians may ask themselves, “which num­ bers are important . . . and why?” if libraries focused on conversations, there might be some clarity and cohesion between statistics and other outcomes. suddenly, the number of reference questions can be linked to items cat­ aloged or to circulation numbers . . . they are all markers of the scope and scale of conversations within the library context. this approach might enable the library com­ munity to better identify important conversations and demonstrate direct contributions to these conversations across functions. for example, a school district identifies early literacy as important. there is a discussion about public policy options, new programs, and school goals to achieve greater literacy in k–5. the library should be able to track two streams in this conversation. the first is the one libraries are accustomed to counting; that is, the library’s contribution to k–5 literacy (participation in book talks, children’s events, circulation of children’s books, reference questions, and so on). but the library also can document and demonstrate how it furthered the conversation about children’s literacy in general. it could show the resources provided to community offi­ cials. it could show the literacy pathfinders that were created. the point of this example is that the library is both participant in the conversation (what we do to pro­ mote early literacy) and facilitator of conversation (what we do to promote public discourse). article title | author 19participatory networks | lankes, silverstein, and nicholson 19 the theoretical discussion leads us to a discussion about the second topic of this technology brief: pragmatic aspects of the knowledge as conversation approach, or a participatory approach, as it will be called. as new technologies are developed and deployed in the current environment of limited resources, there must be some means of evaluating their utility. a technology’s util­ ity is appropriately measured against a given library’s mission, which is, in turn, developed to respond to the needs of the community that library serves. first, how­ ever, let us identify some of the new technologies and describe them briefly. ■ participatory networking, social networks, and web 2.0 let us now move from the theoretical to the opera­ tional. the impetus behind this article is the relatively recent emergence of a new group of internet services and capabilities. suddenly, terms such as wiki, blog, mashup, web 2.0, and biblioblogosphere have become commonplace. as with any new wave of technological creation, these terms can seem ambiguous. they also come wrapped in varying amounts of hype. they may all, however, be grouped under the phenomenon of par­ ticipatory networking. while we now have a conceptual framework to evaluate these technologies that support participatory networking (for example, do they further conversa­ tions), we still need to know the basics of the terminol­ ogy and technologies. this section outlines key concepts in the pragmatics of participatory networking. the section after this one will join the theoretical and operational to outline key chal­ lenges and opportunities for the library world. we begin with web 2.0. web 2.0 much of what we call participatory networking, at least the technological foundation of it, stems from developments in web 2.0.5 as with many buzzwords, the exact definition of web 2.0 is not clear. it is more an aggregation of concepts that range from software development (loosely coupled application programming interfaces [apis] and the ease of incorporating features across platforms) to abstrac­ tions (the user is the content). what pervades the web 2.0 approach is the notion that internet services are increas­ ingly facilitators of conversations. the following sections describe some of the characteristics of web 2.0. web 2.0 characteristic: social networks a core concept of web 2.0 is that people are the content of sites; that is, a site is not populated with information for users to consume. instead, services are provided to individual users for them to build networks of friends and other groups (professional, recreational, and so on). the content of a site, then, comprises user­provided infor­ mation that attracts new members of an ever­expanding network. examples include: ■ flickr. flickr (www.flickr.com) provides users with free web space to upload images and create photo albums. users then can share these photos with friends or with the public at large. flickr facilitates the creation of shared photo galleries around themes and places. ■ the cheshire public library. the teen book blog (http://cpltbb.wordpress.com) at the cheshire public library offers book reviews created only by the stu­ dents who use the library. ■ memorial hall library. the memorial hall library in andover, massachusetts, offers podcasts of poetry contests in which the content is created by students (www.mhl.org/teens/audio/index.htm). ■ libraries in myspace. myspace searches show that there are myspace sites for hundreds of individual libraries and scores of library groups. alexandrian public library (apl), for example, has established a site at myspace (www.myspace.com/teensatapl). this practice is growing among public libraries and is an attempt to reach out to users in their preferred online environments. in this venue, the more friends a library’s myspace site has, the more successful it may be considered. as of this writing, apl had sev­ enty­five friends and fifteen comments. the brooklyn college library had 2,195 friends and 270 comments. web 2.0 characteristic: wisdom of crowds there has been some research into the quality of mass decision­making.6 that research shows how remarkably accurate groups are in their judgments. web 2.0 pools large groups of users to comment on decisions. this aggregation of input is facilitated by the ready availabil­ ity of social networking sites. certainly, this approach of community organization and verification of knowledge also has its detractors. many, for example, question the wisdom seen in some entries of wikipedia. yet, recent articles have compared this mass editing process favor­ ably to traditional sources of information, such as the encyclopedia britannica.7 examples include: ■ ebay. ebay has perhaps the most studied and copied community policing and reputation systems. all buyers and sellers can be rated. the aggregation of many users’ experiences create a feedback score that is equivalent to a group credibility rating (see figure 1). these kinds of group feedback systems can now be seen in most major internet retailers. ■ librarything. librarything.com makes book recom­ 20 information technology and libraries | december 200720 information technology and libraries | december 2007 mendations based on the collective intelligence of all users of the site. the greater the pool of collective intelligence, the more information available to the user for decision­making. ■ the diary project. the diary project library (www. diaryproject.com) is a non­profit organization that encourages teens to write about their day­to­day experiences growing up. the goal of this site is to encourage communication among teens of all cul­ tures and backgrounds, provide peer­to­peer support, stimulate discussion, and generate feedback that can help ease some of the concerns teens encounter along the way and let them know that they are not alone. to that end, the site comprises thousands of entries in twenty­four categories. because of the great number of entries, most youth can find helpful materials. web 2.0 characteristic: loosely coupled apis an api provides a set of instructions (messages) that a programmer can use to communicate between applica­ tions. apis allow programmers to incorporate one piece of software they may not be able to directly manipulate (code) into another. for example, google maps has made a public api that allows web page designers to include satellite images into their web pages with little more than a latitude and longitude.8 apis vary in their ease of integration. loosely coupled apis allow for very easy integration using high­level scripting languages such as javascript9. examples include: ■ google maps. google maps displays street or sat­ ellite maps showing markers on specific locations provided by an external source with simple sets of longitudes and latitudes. it becomes extremely easy to create geographic information systems with little knowledge of gis principles. ■ flickr. flickr provides easy means to integrate hosted images into other web pages or applications (as with a google map that shows images taken at a specific location). ■ youtube. youtube (www.youtube.com) provides users with the capability to upload and comment upon video on the internet. it also allows for easy integration of the videos into other web pages and blogs. with a simple line of html code, anyone can access streaming video for their content. web 2.0 characteristic: mashups mashups are combinations of apis and data that result in new information resources and services.10 this ease of incorporation has led to an assumption of a “right to remix.” in the world of open source software and the creative commons, the right to remix refers to a grow­ ing expectation among internet users that they are not limited by the interfaces and uses presented to them by a single organization. examples include: ■ chicagocrime.org. an often­cited example of a mashup is chicagocrime.org, which uses google maps to plot crime data for the city of chicago. users can now see exactly which street corner had the most murders. figure 2 shows a marker at the location of every homicide in chicago from november 2, 2005, to august 2, 2006. ■ book burro. book burro (http://bookburro.org/ about.html) “is a web 2.0 extension for firefox and flock. when it senses you are looking at a page that contains a book, it will overlay a small panel which when opened lists prices at online bookstores such as amazon, buy, half (and many more) and whether the book is available at your library.” ■ library lookup. the mit library lookup greasemonkey script for firefox (http://libraries. mit.edu/help/lookup.html) searches mit’s barton catalog from an amazon book screen. web 2.0 characteristic: permanent betas the concept of a permanent beta is, in part, a realization that no software is ever truly complete so long as the user community is still commenting upon it. for example, google does not release services from beta until it has achieved a sufficient user base, no matter how fixed the underlying source code is.11 permanent beta also is a design strategy. large applications are broken into smaller constituent parts that can be manipulated sepa­ rately. this allows large applications to be continually figure 1. a seller’s profile shows a potential buyer the ebay community’s current estimation of a seller’s credibility. article title | author 21participatory networks | lankes, silverstein, and nicholson 21 developed by a more diverse and distributed community (as in open source). examples include: ■ google labs. google has a site named “google labs” (http://labs.google.com) that puts out company­ generated tools and services. in fact, part of a google employee’s work time is dedicated to creating the resources and tools through personal projects and exploration. these tools and services remain a part of the “lab” until they are finished and have sufficient user bases. projects (see figure 3) range from the simple (google suggest, which provides a dropdown box of possible search queries as you being to type your search terms) to the extensive (google maps, which started as a google lab project). ■ mit libraries. the mit libraries are experimenting with new technologies to help make access to informa­ tion easier. the tools below are offered to the public with an appeal for feedback and additional tools, and the there is a permanent address designed just to collect feedback from the beta­phase tools, which include: ■ the new humanities virtual browsery, which highlights new books and incorporates an rss feed, the ability to comment on books, links to book reviews, availability information, and links to other books by the same author. ■ the libx—mit edition (http://libraries.mit. edu/help/libx.html), which is a firefox toolbar that allows users to search the barton catalog, vera, google scholar, the sfx fulltext finder, and other search tools; it embeds links to mit­ only resources in amazon, barnes & noble, google scholar, and nyt book reviews. ■ the dewey research advisor business and economics q&a (http://libraries.mit.edu/help/ dra.html), which provides starting points for specific research questions in the fields of busi­ ness, management, and economics. web 2.0 characteristic: software gets better the more people use it an increasing number of web 2.0 sites emphasize social networks, where these services gain value only as they gain users. malcolm gladwell recounts this principle and the work of kevin kelly with an earlier telecommunica­ tions network, the network of fax machines connected to the phone system: the first fax machine ever made . . . cost about $2,000 at retail. but it was worth nothing because there was no other fax machine for it to communicate with. the second fax machine made the first fax machine more valuable, and the third fax made the first two more valuable, and so on. . . . when you buy a fax machine, then, what you are really buying is access to the entire fax network—which is infinitely more valuable than the machine itself.12 with social networking sites, and all sites that seek to capitalize on user input (reviews, annotations, profiles, etc.), the true value of each site is defined by the number of people it can bring together. a classic example of this characteristic is amazon. amazon sells books and other merchandise, but, in reality, amazon is very much about the marketing of information. amazon gains tremendous value by allowing its users to review and rate items. the more people use amazon and the more they comment, the more visibility these active users gain and the more credibility markers they take on. web 2.0 characteristic: folksonomies a folksonomy is a classification system created in a bottom­up fashion with no central coordination. this differs from the deductive approach of such classifica­ tions systems as the dewey decimal system, where the world of ideas is broken into ten nominal classes.13 it also differs from other means of developing classifications where some central authority determines if a term should be included. in a folksonomy, the members of a group simply attach terms (or tags) to items (such as photos or blog postings), and the aggregate of these terms is seen as the classification. what emerges is a classification scheme that prioritizes common usage (the most­used tags) over semantic clarity (if most people use “car,” but some use “cars,” they are seen as different terms, and the tag “auto­ mobile” has no real relationship within the aggregate classification). examples include: figure 2: screenshot of chicagocrime.org 22 information technology and libraries | december 200722 information technology and libraries | december 2007 ■ penntags. penntags (http://tags.library.upenn.edu/ help) is a social bookmarking tool for locating, orga­ nizing, and sharing one’s favorite online resources. members of the penn community can collect and maintain urls, links to journal articles, and records in franklin, the online catalog, and vcat, the online video catalog. once resources are compiled, users can organize them by assigning tags (free­text key­ words) or by grouping them into projects according to specific preferences. penntags also can be used collaboratively, as it acts as a repository of the varied interests and academic pursuits of the penn com­ munity, and a user can find topics and other users related to his or her own favorite online resources. ■ hillsdale teen library. the hillsdale teen library (www.flickr.com/photos/hillsdalelibraryteens) uses flickr to post pictures of events at the hillsdale teen library (figure 4). the resulting tag view is repre­ sented in figure 5. these tags allow users to easily retrieve the images in which they are interested. there are more characteristics of web 2.0, but these give some overall concepts. core new technologies: ajax and web services as we have just discussed, web 2.0 is little more than set of related concepts, albeit with a lot of value being currently attached to these concepts. these concepts are supported by two underlying technologies that have facilitated web 2.0 development and brought a substantially new (and improved) user experience to the web. the first is ajax, which allows a more desktop­like experience for users. the second is the advent of web services. these technolo­ gies are not necessary for web 2.0 concepts, but they have made web 2.0 sites much more compelling. ajax ajax stands for asynchronous javascript and xml.14 it is a set of existing web technologies brought together. at the most basic, ajax allows a browser (the part the user interacts with) and a server (where the data resides) to send data back and forth without needing to refresh the entire web page being worked on. think about the web sites you work with. you click on a link, the browser freezes and waits for the data, then draws it on the screen. early versions of such sites as mapquest would show a map. if you wanted to zoom into the map, you would press a zoom icon and wait while the new map, and the rest of the web page was redrawn. compare this to google maps, where you click in the middle of a map and drag left or right and the map moves dynamically. we are used to this kind of interaction in desktop applications. click and drag has become second nature on the desktop, and ajax is making it second nature on the web, too. another ajax advantage is that it is open and requires only light programming skills. javascript on the client and almost any server­side scripting language (such as active server pages or php) are easily accessible languages. this fact allows for both fast development and easier integration with existing systems. as an example, it should now be easier to bring more interactive web interfaces to existing online catalogs. web services web services allow for software­to­software interactions on the web.15 using web protocols and xml, applications exchange queries and information in order to facilitate the larger functioning of a system. one example would be a system that uses an isbn number to query multiple online catalogs and commercial vendors for availability (and price) of a book. this simple process might be part of a much larger library catalog that shows users a book and its availability. the point is, that unlike federated search systems such as z39.50, web services are small. they also tend to be lightweight (that is, limited in what they do), and are aggregated for greater functionality. this is the technological basis for the loosely coupled apis dis­ cussed previously. library 2.0 library 2.0 is a somewhat diffuse concept. walt crawford, in his extended essay “library 2.0 and ‘library 2.0,’” found sixty­two different (and often contradictory) views and seven distinct definitions of library 2.0.16 it is no wonder that people are confused. however, it is natural for emerging ideas and groups to function in an environ­ figure 3: screenshot of current google lab projects article title | author 23participatory networks | lankes, silverstein, and nicholson 23 ment of high ambiguity. for use in this technology brief, the authors see library 2.0 as an attempt to apply web 2.0 concepts (and some longstanding beliefs for greater com­ munity involvement) to the purpose of the library. in the words of ormsby, “the purpose of a library is not to . . . showcase new gadgetry . . . ; rather, it is to make possible that instant of insight when all the facts come together in the shape of new knowledge.”17 in the case of library 2.0, the new gadgetry discussed in the previous section comprises a group of software applications. how the applications are used will determine whether they support ormsby’s “instant of insight.” many libraries and librarians already are pursuing this goal. some, for instance, are using blogs to reach other librarians, their own users (on their own web sites), and potential users (using myspace and other online communities). they are using wikis to deliver reports, teach information literacy, and serve as repositories. one has developed an api that allows wordpress posts to be directly integrated into a library catalog. clearly, the internet and newer tools that empower users seem to be aligned with the library mission. after all, librarians blogging and allowing the catalog to be mashed up can be seen as an extension of current information services. but this abundance of new applications poses a challenge. given the speed with which new tools are invented, librarians may find it difficult to create strate­ gies that include all the desired services that they make possible. for every new application that becomes avail­ able, library administrators must decide whether it can serve the library, how to use it, and how to find additional resources to manage it (for example, “now we can do this. but why should we?”). this problem stems from focusing excessively on the technology. librarians should instead focus on the phenomena made possible by the technology. most important of these phenomena, the library invites participation. as chad and miller state: library 2.0 facilitates and encourages a culture of participation, drawing upon the perspectives and con­ tributions of library staff, technology partners and the wider community. library 2.0 means harnessing this type of participation so that libraries can benefit from increasingly rich collaborative cataloguing efforts, such as including contributions from partner libraries as well as adding rich enhancements, such as book jackets or movie files, to records from publishers and others. library 2.0 is about encouraging and enabling a library’s community of users to participate, contribut­ ing their own views on resources they have used and new ones to which they might wish access. with library 2.0, a library will continue to develop and deploy the rich descriptive standards of the domain, whilst embracing more participative approaches that encourage interaction with and the formation of com­ munities of interest.18 the carte blanche statement that users participating in the library is “good,” however, is insufficient. library administers must ask, “what is the ultimate goal?” in summary, current initiatives in the library world to bring the tools of web 2.0 to the service of library 2.0 are exciting and innovative, and, more to the point, they are supportive of the library’s purpose. they may, however, incur costs, such as monitoring blogs and wikis, and cre­ figure 4: hillsdale teen library figure 5: hillsdale teen library flickr site 24 information technology and libraries | december 200724 information technology and libraries | december 2007 ating content and corresponding with users that stretch already inadequate resources even further. ultimately, the value of library 2.0 concepts requires us to answer some important questions: will they be used to further knowledge, or will they simply create more work for librarians? what does the next version of library 2.0 look like? is its mission the same, and only the tools dif­ ferent? what makes the library different from myspace— simply a legacy? should we incorporate new services into the current library offerings? how do we, as facilitators of conversations, point the way to the next generation of library? it is hoped that some of the concepts in participa­ tory librarianship may answer these questions and help further the innovations of the library 2.0 community. participatory networks the authors use the phrase “participatory networking” to encompass the concept of using web 2.0 principles and technologies to implement a conversational model within a community (a library, a peer group, the general public, and so on). why not simply adopt social networking, web 2.0, or library 2.0 for that matter? let us examine each term’s limitations: ■ social networking: social network sites such as myspace and facebook have certainly captured public attention. they also have proven very popular. in their short life spans, these sites have garnered an immense audience (myspace has been ranked one of the top destination sites on the web) and drawn much atten­ tion from the press.19 some of that attention, however, has been very negative. myspace, for example, has been typified as a refuge for pedophiles and online predators. even the television show saturday night live has parodied the site for the ease with which users can create false personas and engage in risky online behaviors.20 to say you are starting a social networking site in your library may draw either enthusiastic support, vehement opposition (“social networking experiment in my library?!”), or simply confused looks. add to the potential negative con­ notations the ambiguity of the term. is a blog a social networking site? is flickr? to compound this confu­ sion, the academic domain of social network theory predates myspace by about a decade. ■ web 2.0: ambiguity also dogs the web 2.0 world. for some, it is technology (blogs, ajax, web ser­ vices, and so on). for others, it is simply a buzzword for the current crop of internet sites that survived the burst of the dot­com bubble. in any case, web 2.0 certainly implies more than just the inclusion of users in systems. ■ library 2.0: as stated before, the term library 2.0 is a vague term used by some as a goad to the library community. further, this term limits the discussion of user­inclusive web services to the library world. while this brief focuses on the library community, it also sees the library community as a potential leader in a much broader field. so, ultimately, the authors propose “participatory net­ working” as a positive term and concept that libraries can use and promote without the confusion and limitations of previous language. the phrase “participatory network” also has a history of prior use that can be built upon. it represents systems of exchange and integration and has long been used in discussions of policy, art, and government.21 the phrase also has been used to describe online communities that exchange and integrate information. ■ libraries as participatory conversations so where are we? we started with the abstract statement that knowledge is created through conversation. we then looked at the current landscape of technologies that can facilitate these conversations and showed examples of how libraries, other industries, and individuals are using these technologies. in this section we combine the larger framework with the technologies to see how libraries can incorporate participatory networks to further their knowledge mission. participatory librarianship in action let us look specifically at how participatory networks can be used in the library’s role as facilitator of knowledge through conversation. an obvious example is libraries hosting blogs and wikis for their communities, creat­ ing virtual meeting spaces for individuals and groups. indeed, these are increasingly useful functions for librar­ ies. they meet a perceived need in the community and can generate excitement both within the library and in the community. the idea of creating online sites for individu­ als and organizations makes sense for a library, although it is not without difficulties (see the section on challenges and opportunities). libraries also could use freely avail­ able (and increasingly easy to implement) open source software to create library versions of wikipedia (with or without enhanced editorial processes). another way for libraries to offer these services would be through a cooperative or other third­party vendor. such a service easily can be seen as a knowledge management activity capturing and providing local expertise while linking this expertise to that produced at other libraries. another reason for libraries to engage in participatory networking is that one library can more easily collaborate article title | author 25participatory networks | lankes, silverstein, and nicholson 25 with other libraries in richer dialogues. we currently have systems that connect our online catalogs and share resources through interlibrary loan. these conduits exist and can be used for the transferal of richer data, as has been proved through collaborative virtual reference sys­ tems. in our current systems, as in traditional library practice, when users are referred to other libraries, they are sent out and not brought back. in a participatory library setting, libraries would facilitate a conversation between the user, the community of the local library, and then through the developed conduits, other libraries and their communities. the end result would be a seamless web of libraries where the user can ignore the intrica­ cies of the library’s organization structure and boundar­ ies, and in which the libraries are using the best local resources to meet local needs. bringing libraries seamlessly together to participate in conversations with a single user has another sig­ nificant advantage: the library would make it easy for users to join the conversation regardless of where they are, through the presentation of a single façade. there is, for example, only one google, one amazon, and one wikipedia. why should users have to search from among thousands of libraries to find the conversations they want? participatory networking will be most effective when libraries work together, when the whole is greater than its parts. we currently see elements of the participatory library in the oclc open worldcat project. for example, users searching google may come across a listing provided by oclc. after selecting the entry for the book, the user can then jump to his or her own local library’s information about the book. users do not have to know which library to visit to find a book near them. extending this concept to conversations, one goal of these participatory networks is to make it easier for the user to enter a conversation with the library without having to work to discover their own specific entry points. however, ensuring this effective seamless access to the library will require more than simply adding ele­ ments of participatory networking around the library’s edges. adding services such as blogs and wikis may be seen merely as adjunct to current library offerings. as with any technological advance, scarce resources must be weighed against a desire to incorporate new services. do we expand the collection, improve the web site, or offer blogs to students? a better approach for making these kinds of decisions is to look at the needs of the community served in context with the commonly accepted, core tasks of a library, and see how they can be recast (and enhanced) as conversational, or participatory, tools. in point of fact, every service, patron, and access point is a starting point for a conversation. let’s start with the catalog. if the catalog is a conversation, it is decidedly formal and, more importantly, one way. think of today’s catalog as the educational equivalent of a college lecture. a for­ mal system is used to serve up a series of presentations on a given topic (selected by the user). the presentations are rigid in their construction (marc, aacr2, and so on). they follow an abstract model (relevance scores, some­ times alphabetical listings), and provide minimal oppor­ tunities to the receiver of the information to provide feedback or input. they provide no constructive means for the user to improve or shape the conversation. even recent advances in catalog functions (dynamic, graphical visualizations; faceted searching; simple search boxes’ links to non­collection resources) do little more than make the presentation of information more varied. they are still not truly interactive because they do not allow user participation; they do not allow for conversation. to highlight the one­way nature of the catalog, ask a simple question: what happens when the user doesn’t find something? do we assume that the information is there, but that the user is simply incapable of finding it (in which case the catalog presents search tips, refers the patron to an expert librarian who is capable, or offers more information literacy instruction)? do we assume that the information does not exist (refer the patron to interlibrary loan, pass him or her on to a broader search engine)? do we assume that the catalog itself is limited (refer the user to online databases, or other finding aids)? what if we assume that the catalog is just the current place a user is involving in an ongoing conversation —what would that look like? how can such a traditionally rigid system (in concept, more than in any one feature set) be made more participa­ tory? what if the user, finding no relevant information in the catalog, adds either the information or a place­ holder for someone else to fill in the missing information? possibly the user adds information from his or her exper­ tise. however, assuming that most people go to a catalog because they don’t have the information, perhaps the user instead begins a process for adding the information. the user might ask a question using a virtual reference service; at the end of the transaction, the user then has the option to add the question, along with the answer and associ­ ated materials, to the catalog. or perhaps, the user simply leaves the query in the catalog for other patrons to answer, requesting to be notified when a response is posted. in that case, when a new user does a catalog search and runs across the question, he or she can provide an answer. that answer might be a textual entry (or an image, sound, or video), or simply a new query that directs the original questioner or new patrons to existing information in the catalog (user­created see also entries in the catalog). the catalog also can associate conversations with any data point. for example, a user pulls up the record for a book she or he feels might be relevant to an information need she or he is having. this process starts a conver­ sation between that user and the library, its users, and 26 information technology and libraries | december 200726 information technology and libraries | december 2007 authors of associated works. the user can see comments and ratings associated with this book from not only users of this library, but users of other libraries. also associated is a list of related works and the full audio of a lecture by the author. the user also might be directed to an in­ person or online book group that is reading that book. the point is that the catalog facilitates a conversation as opposed to simply presenting what it “knows” about a topic and then stepping out of the process. the catalog, then, does not simply present information, but instead helps users construct knowledge by allowing the user to participate in a conversation. there are other means of improving (and linking) systems in a conversational library. take the implicit link between the catalog and circulation. of course, these systems have always been linked in that items found in the catalog can be checked out, and checked out items have their status reflected in the catalog. but this kind of state information is a pretty meager offering. imagine using circulation data to improve the actual functionality of the catalog. take the example of a user who is search­ ing the catalog for fictional books on magic. currently, a relevance score between an item’s metadata and the query is computed and then all the items are ranked in a retrieval set. this relevance score can be computed in many ways, but is usually based on the number of times a keyword appears in the record and the placement of that keyword in the metadata record (giving preference to terms appearing in certain marc fields, such as titles). what is missing is the actual, real­world circulation of an item. wouldn’t it make sense, given such an abstract query, to present the user with harry potter first (but not exclusively)? what if we added circulation data to our relevance rankings: how many times this item has been checked out? it turns out that using a simple statistic is amazingly powerful. it is akin to google’s page rank algorithm that presents sites most linked to higher in the results. also, for those worried that users would be flooded with only popular materials, studies show that while these algorithms do change the very top ranked material, the effect quickly fades so that the user can still easily find other materials. another consideration for adjusting a search is to allow the user to tweak the algorithms used to retrieve works. in the example above, a user could turn off the popularity feature. the user also could toggle switches for currency, authority, and other facets of relevancy rankings. the conversational model requires us to rethink the catalog as a dynamic system with data of varying levels of currency and, frankly, quality, coming into and out of the system. in a conversational catalog, there is no reason that some data can’t exist in the catalog for limited dura­ tions (from years to seconds). records of well­groomed physical collections may be a core and durable collection in the catalog, but that is only one of many types of infor­ mation that could exist in the catalog space. furthermore, even this core data can be annotated and linked to (and from) more transient media. so, the user might see a review from a blog as part of a catalog record on one day, but when she or he pulls the record up again in a few days, that review might be absent, the blog writer hav­ ing withdrawn the comment. this is akin to weeding the collection; however, it would happen in a more dynamic fashion than occurs with the content on library shelves. the conversational model also can be used in other areas of the library. what do we digitize? what do we select? what programs do we offer? what do we pre­ serve? the empowered user can participate in answer­ ing all of these questions but does not replace the expert librarian; rather, the user contributes additional and diverse information and commentary. in fact, the catalog scenario just proposed already assumes that the library catalog does more than store metadata. in order for the scenario to work, the catalog must store questions, answers, video, audio—in essence the catalog must be expanded and integrated with other library systems so that a final participatory library system can present a coherent view of the library to patrons. the next section lays out a sort of roadmap for these enhance­ ments and mergers. framework for integration of participatory librarianship as has been noted, participatory networks and libraries as conversations are not brand new concepts sprung from the head of zeus. instead, they are means to integrate past and current innovations and create a viable plan forward. figure 6 provides a sort of road map of how the library might make the transition from current systems to a truly participatory system. it includes current systems, systems under development (such as federated searching), and new concepts (such as the participatory library). it seeks to capture current momentum and push the field forward to a larger view instead of getting bogged down in the intricacies of any one development activity. along the left side of the graph are current library systems. while the terminology may differ from library to library, nearly every system can be found on today’s library web sites. by showing the systems together, the problems of user confusion and library management burden become obvious. users must often navigate these systems based on their needs, and often with little help. should they search the catalogs first, or the databases? isn’t the catalog really just another database? which data­ base do they choose? in our attempts to serve the users better by creating a rich set of resources and services, we have instead complicated their information­seeking lives. as one librarian puts it, “don’t give me one more system i, or my patrons, have to deal with.” article title | author 27participatory networks | lankes, silverstein, and nicholson 27 from the array of systems on the left side, we can see that libraries have not been doing themselves any favors either. we are maintaining many systems, therefore mak­ ing the calls for yet more systems not only impractical but unwise. the answer is to integrate systems, combining the best of each while discarding the complexity of the whole. the library world is in the midst of doing just that. this section seeks to highlight promising developments in integrating library systems well beyond the library catalog and to highlight not only an ideal endpoint, but also how this ideal system is truly participatory. merging reference and community involvement the functional area furthest along in the integration of participatory librarianship is reference; as reference is most readily recognizable as a conversation, this comes as no surprise. over the last decade, reference services have gone online and have led to shared reference ser­ vices. more importantly, reference done online creates artifacts of reference conversations: electronic files than can be cleaned of personal information and placed in a knowledge base and used as a resource for other users. a new development in reference is the reference blog, in which multiple librarians and other users can be part of a question­answering community with conversations that can live on beyond a single transaction. another functional area of libraries that is already involved with participatory librarianship is community involvement. for decades, public libraries have supported local community groups through meeting spaces. some libraries now are hosting web spaces for local groups. as libraries incorporate participatory technologies into their offerings, they can create virtual places such as discussion forums, wikis, and blogs for these community groups to use. if there are standards for these discussion areas, then groups from different communities also could easily participate in shared boards; this makes sense for groups such as weight watchers or alcoholics anonymous that have local branches and national involvement. in an academic setting, these groups can be student, faculty, or staff organizations or courses. in addition to reference and hosted community con­ versations, the library has been actively creating digi­ tal collections of materials (either through digitization, leasing service from content providers, or capturing the library’s born digital items). parallel to the digital collec­ tion building of library materials is an active attempt to create institutional repositories of faculty papers, teacher lesson plans, organizational documentation, and the like. these services are participatory systems in which col­ lections come from users’ contributions, and they may evolve into digital repositories that include both user­ and librarian­created artifacts. these different conversations can be archived into a single repository, and, if properly planned, the refer­ ence conversations can live alongside, and eventually be intermingled with, the community conversations, and the digital repository (which, after all, though formal, is a community conversation) into a community repository. community repositories allow librarians to be more eas­ ily involved in the conversations of the community and capture important artifacts of these conversations for later use. merging library metadata into an enhanced catalog participatory librarianship can be supported by another functional area of the library: collections. traditionally, the collection comprises books, magazines, and other information resources paid for by the library. electronic resources, such as databases that are leased instead of purchased, make up a large portion of library expen­ ditures. more recently, web­based resources (external feeds and sites) have been selected and added to the virtual collection. several kinds of finding aids are used to locate these information resources. the catalog and databases both contain descriptions of resources and searching interfaces. in order to improve access, libraries include records for databases within the catalog. conversely, federated search­ ing tools combine the records from different databases and could allow the retrieval of both books and articles by com­ bining records from the traditional catalog and databases into one tool. if community­created resources are part of the catalog, then these resources also would be findable alongside other traditional library resources. the tools for describing information resources also can be participatory. in traditional librarianship, the librarians provide metadata that patrons then use to make selections. figure 6: road map of how the library might make the transition from current systems to a truly participatory system. 28 information technology and libraries | december 200728 information technology and libraries | december 2007 by examining this use data, recommender systems can be created to help users locate new materials. in participatory networking, patrons will be encouraged to add comments about items. if standards are used for these comments, then they can be shared among libraries to create larger pools of recommendations. as these comments are analyzed, they can be combined with usage databases to create stronger recommender systems to present patrons with additional choices based upon what is being explored. the end result is an enhanced catalog that allows users and libraries to find information regardless of which sys­ tem the information resides in. however, the enhanced catalog is still just that, a catalog. it contains surrogates of digital information and is managed separately from the artifacts themselves. in the case of physical items, this may be all the library systems can manage, but in the case of digital content, there is one more step that needs to be taken. namely, the artificial barrier between catalog (defined as inventory control system) and content (housed in the community repository) must come down. building the participatory library at this point in the evolution of distributed systems into a truly integrated library system, the participatory library, we have two large collections: one of resources, and one of information about the resources. the first collection of digital content, the community repository, is built by the library and its users collaboratively. the second collection, the enhanced catalog, includes metadata, both formal and user­created (such as ratings, commentary, use data, and the like). both the community repository and the enriched catalog are participatory. yet to realize the dream of a seamless system of functionality (seamless to the user and the library), these two systems must be merged, allow­ ing users to find resources and, much more importantly, conversations. furthermore, the users must be able to add to metadata (such as tags to catalog records) and content (such as articles, postings to a wiki, or personal images). the result may be conceived of as a single integrated infor­ mation resource, which, for the purposes of this conversa­ tion, is called the participatory library. users may access the participatory library directly through the library or as a series of services in google, myspace, or their own home pages. the point is that the access to the library takes place at the point of conversa­ tion, not at the point the user realizes he or she needs information from the library. conversations and preservation the conversation model highlights the need for preserva­ tion. aside from simply providing systems that facilitate conversation, libraries serve as the vital community memory. conversations construct knowledge, but some­ one must remember what has already been said and know how to access that dialog. scientific conversations, for example, are built on previous conversations (theories, studies, methods, results, and hypotheses). capturing conversations and playing them back at the right time is essential. this might mean the preservation of artifacts (maps, transcripts, blueprints, photographs), but also it means the increasingly important tasks of capturing the digital dialogs. this highlights the need for institutional repositories (that will later be integrated seamlessly with other library systems, as previously discussed). specifically, web sites, lectures, courseware, and articles must be kept. further, they must be kept in true conversa­ tional repositories that capture the artifacts (the papers), the methods (data, instruments, policy documents), and the process (meeting notes, conversations, presentations, web sites, electronic discussions). they must be kept in information structures that make them readily available as conversations; in other words, users must be able to search for materials and reconstruct a conversation in its entirety from one fragment. being where the conversation is imagine the conversations that are going on in your local library as you read this. imagine the physicist chatting with the gardener, and the trustee talking with the volunteer who is reading the latest best­seller. what knowledge can be gleaned from these novel interac­ tions? can you measure it? can you enhance it? can you capture it? can you recall it when it would be precisely what a user needs? note also that these conversations do not belong solely to the library. the library is only part of the con­ versation. faced with the daunting variety of resources available on the web, many organizations try to become the single point of entry into it. remember that conversa­ tions are varied in their mode, places, and players, and, more importantly, that they are intensely personal. this means that participants need to have ownership in them, and often in their locations as well. this also means that the library, as facilitator, needs to be varied in its modes and access points. in many cases, it is better to either create a personal space in which users may converse, or, increasingly, to be part of someone else’s space. what we can learn from web 2.0’s mashups is that smaller sets of limited (but easy to access) functionalities lead to greater incorporation of tools into people’s lives. in the chicagocrime–google maps mashup, combining maps from google and chicago crime statistics, it was important for the host of the site to brand the space and shape the interface for his conversation on crime. can your library functions be as easily incorporated into these types of conversations? can a user search your catalog and present the results on his or her web site? the point is that libraries need to be proactive in a new way. instead of article title | author 29participatory networks | lankes, silverstein, and nicholson 29 the mantra, “be where the user is,” we need to, “be where the conversation is.” it is not enough to be at the users’ desktops; you need to be in their e­mail program, in their myspace pages, in their instant messaging lists, and in their rss feed readers. all of these examples point to a significant mental shift that librarians will need to make in moving from delivering information from a centralized location to delivering information in a decentralized manner where the conversations of users are taking place. the catalog example presented earlier is an example of a centralized place for conversations. what if, instead of only being in a catalog, the same data were split into smaller components and embedded in the user’s browser and e­mail pro­ grams? just as google’s mail system embeds advertising based upon the content of a message, the library could provide links to its resources based upon what a user is working on. by disaggregating the information within its system, the library can deliver just what is needed to a user, provide connections into mashups, and live in the space of the user instead of forcing the user to come to the space of the library. challenges and opportunities there is clearly a host of challenges in incorporating par­ ticipatory networks and a participatory model into the library. this is to be expected when we are dealing with something as fundamental as knowledge and as personal as conversations. we consider four major challenges that must be met by libraries before they can truly get into the business of participatory librarianship. technical there is a rich suite of participatory networking software that libraries can incorporate into their daily operations. implementing a blog, a wiki, or rss feeds these days is not a hard task, and they can easily be used to deliver information about library services and conversations to the user’s space. furthermore, these systems are often tested in very large­scale environments and are, in some cases, the same tools used in large participatory network­ ing sites such as wikipedia and blogger. some of these packages are commercial, but others are open source software. open source software is cheaper, easier to adapt, and, in some cases, more advanced. the downside to open source is that it requires a considerable amount of technical knowledge by the library (but not as much as one might think) and does not come with a technical support hotline. the largest technological impediment, however, may be the currently installed base of software within librar­ ies. integrated library systems have a long history and include a broad range of library functions. legacy code and near monolithic systems have restricted the easy exchange of a diverse set of information. were these sys­ tems written today, they would use modular code and loosely coupled apis and allow customers much more interface customizability. these changes may come to integrated library systems (as customers are demanding it), but it may take years. several libraries are currently attempting to pick apart these integrated systems themselves. often, libraries go to the underlying databases that hold the library metadata or create their own data structures, such as the university of pennsylvania data farm project.22 once components of this system are exposed, the catalog simply becomes another database that can be federated into new and uni­ fied interfaces. however, such integration requires a great deal of technological expertise. there is an opportunity for integrated library system vendors or large consortial groups such as oclc to move quickly into this space. in the meantime, there is an opportunity for the larger library community. this technology brief was created in response to a perceived need. whether evi­ denced in the library 2.0 community or in conversations at lita, libraries are now interested in incorporating new web technologies into their offerings and opera­ tions. the technologies under consideration here pres­ ent platforms for experimentation. rather than setting up thousands of separated experiments, however, the library community should create a participatory net­ work of its own. the technology certainly exists to create a test bed for libraries to set up various combinations of communication technologies (blogs, tagging, wikis), to test new web services against pooled data (catalog data, metadata repositories, and large scale data sets), and even to incorporate new services into the current library offerings (rss feeds, for example). by combining resources (money, time, expertise) in a single, large­scale test bed, libraries not only can get greater impact for the their investments, but can directly experience life as a connected conversation. these connections, if built at the ground level, will then make it easier for the library to come into existence. terminology can be clarified, claims tested, and best practices collaboratively developed, greatly accelerating innovation and dissemination. operational in addition to being in the conversation business, librar­ ies are in the infrastructure business. one of the most powerful aspects of a library is its ability not only to develop a collection of some type of information, but to maintain it over time. sometimes infrastructure can be problematic (as in the case of legacy systems), but more often than not it provides a stable foundation from which to operate. there are many conversations going on that need infrastructure but have none (or little). think of the opportunities in your community for using the web to 30 information technology and libraries | december 200730 information technology and libraries | december 2007 facilitate a conversation. it might be a researcher want­ ing to disseminate the results of his or her latest study. it might be a community organization seeking funding. it might be a business trying to manage its basic opera­ tional knowledge. the point is that such individuals and community organizations are not in the infrastructure business and could use a partner who is. imagine a local organization coming to the library and, within a few min­ utes, setting up a web site with an rss feed, a blog, and bulletin boards. the library facilitates, but does not own, that individual’s or organization’s conversation. it does form a strong partnership, however, that can be leveraged into resources and support. the true power of participa­ tory networking in libraries is not to give every librarian a blog; it is in giving every community member a blog (and making the librarian a part of the community). in addition, the library can play the role of connecting these conversations to other users when appropriate. participatory libraries allow the concept of com­ munity center (intellectual center, service center, media center, information center, meeting center) to be extended to the web. many public libraries have no problem providing meeting space to local non­profits. why not provide web meeting space in the form of a web site or web conferencing? many academic libraries attempt to capture the scholarly output of their faculties, why not help generate the output with research data stores? the answers to these questions inevitably come back to time and money. however, there is nothing in this brief that says such services have to be free. in fact, the best part­ nerships are formed when all partners are invested in the process. the true problem is that libraries have no idea of how to charge for such services. faculty would be glad to write library support into grants (in the form of web site creation and hosting), but need a dollar figure to include and how long each task will take. many libraries aren’t used to positioning their services on a per item basis, and this makes it difficult to build partnerships. sometimes it is not a lack of money, but a lack of structure to take in money that is the problem. policy as always, it is policy that presents the greatest challenges. the idea of opening the library functions to a greater set of inputs is rife with potential pitfalls. how can libraries use the technologies and concepts of facebook and myspace without being plagued by their problems? how can users truly be made part of the collection without the library being liable for all of their actions? the answers may lie in a seemingly obscure concept: identity management. conversations can range in their mode, topic, and duration. they also can vary in the conversants. the library needs to know a conversant’s status to determine policy (for example, we can only disclose this information to this person), and requires a unique identifier, such as a library card, to uphold it. in traditional libraries, that is the extent of identity management. in a participatory model, distinctions among identi­ ties become complex and graduated, and require us to consider a new approach. this new model, of patrons adding information directly to library systems, is not as radical as it may first appear. we have become very used to the idea of roles and tiered levels of authority in many other settings. most modern computer systems allow for some gradation in user abilities (and responsibilities). online communities have even introduced merit systems, by which continual high­quality contributions to a site equals greater power in the site. think about amazon, wikipedia, even ebay; as users contribute more to the community, they gain status and recognition. from par­ ticipants to editors, from readers to writers, these organi­ zations have seen membership as a sliding scale of trust, and libraries need to adopt this approach in all of their basic systems. we currently do, to a degree, in the form of librarians, paraprofessionals, and other staff. yet even these distinctions tend to be rigid and often class­based, with high walls (such as a master’s degree) between the strata. some of this is imposed by outside organizations (civil service requirements, tenure track, and so on), but a great deal is there by inertia of the field. skillful use of identity management will help librar­ ies avoid the baggage of myspace and facebook. as users grain greater access, greater responsibility, and greater autonomy, libraries need to be more certain of their identities. that is, for a user to do more requires the library to know more. knowing about a user may involve traditional identity verification or tracking an activity trail, whereby intentions can be judged in rela­ tion to actions. these concepts may be expressed as, “the more we know you, the more control you can have in valuable services such as blogging, or the catalog.” the concepts are illustrated in blogger and livejournal, both of which require some level of identity information. in another example, to join livejournal you must be invited, thus the community confers identity. the common theme is that verifying (and building) identity is community­ based. the difference between the library and myspace is that the library works in an established community with traditional norms of identity, whereas myspace is seeking to create a community (where identity is more defined by social connections than actions). both the library and the services mentioned above, however, base their functions and services on identity. ethical as knowledge is developed through conversation, and libraries facilitate this process, libraries have a powerful impact on the knowledge generated. can librarians inter­ fere with and shape conversations? absolutely. should we? we can’t help it. our collections, our reference work, article title | author 31participatory networks | lankes, silverstein, and nicholson 31 our mere presence will influence conversations. the ques­ tion is, in what ways? by dedicating a library mission to directly align with the needs of a finite community, we are accepting the biases, norms, and priorities of the com­ munity. while a library may seek to expand or change the community, it does so from within. when internet filtering became a requirement for fed­ eral internet funding, public and school libraries could not simply quit, or ignore the fact, because they are agents of their communities. school libraries had to accept filtering with federal funding because their parent organizations, the schools, accepted filtering.23 we see, from this example, that libraries may shift from facilitating conversations to becoming active conversants, but they are always doing both. thus, the question is not whether the library shapes conversations, but which ones, and how actively? these questions are hardly new to the underlying principles of librarianship. and nothing in the participa­ tory model seeks to change those underlying principles. the participatory model does, however, highlight the fact that those principles shape conversations and have an impact on the community. ■ recommendations the overall recommendation of this article is that librar­ ies must be active participants in the ongoing conversa­ tions about participatory networking. they must do so through action, by modeling appropriate and innovative use of technologies. this must be done at the core of the library, not on the periphery. rather than just adding blogs and photosharing, libraries should adopt the princi­ ples of participation in existing core library technologies, such as the catalog. anything less simply adds stress and stretches scarce resources even further. to complement this broad recommendation, the authors make two specific proposals: expand and deepen the discussion and understanding of participatory net­ works and participatory librarianship, and create a par­ ticipatory library test bed to give librarians needed participatory skills and sustain a standing research agenda in participatory librarianship. as stated in the outset of this document, what you are reading is limited. while it certainly contains the kernel and essence of participatory networks (systems to allow users to be truly part of services) and participatory librar­ ianship (the role of librarianship as facilitators and actors in conversations in general), the focus was on technology and technology changes. already, the ideas contained in this document have been part of an active conversation. the first draft of this document was made available for public comment via a wiki, e­mail, and bulletin boards, and concepts herein presented at conferences and lec­ tures. however, there is now a need to broaden the scope and scale of the conversation. the theoretical founda­ tions of participatory librarianship need to be rigorously presented. the nontechnical components of the ideas (and the marriage of nontechnical to technical) need to be explored. there are curricular implications: how do we prepare participatory librarians? the nature and form of the library and participatory systems need to be dis­ cussed and examined in theoretical, experimental, and operational contexts. in order to do this, the authors propose a series of con­ versations to engage the ideas. these conversations, both in person and virtual, need to be within the profession and across disciplines and industries. the deeper conversa­ tions need to be documented in a series of publications that expand this document for academics and practitioners. the authors feel, however, that the first proposal must be grounded in action. to complement the more abstract exploration of participatory networks and participatory librarianship, there must be an active playground where conversants can experience firsthand the technologies discussed, and then actively shape the tools of partici­ pation. this is the test bed. this test bed would imple­ ment a participatory network of libraries, and provide a common technology platform to host blogs, wikis, discussion boards, rss aggregators, and the like. these shared technologies would be used to experiment with new technologies and to provide real services to librar­ ies. thus, libraries could not only read about blogging applications, they could try them and even roll them out to their community members. as libraries start new com­ munity initiatives, they could rapidly add wikis and rss feeds hosted at the shared test bed. the test bed would also make all software available to the libraries so they could locally implement technologies that have proven themselves. the test bed would provide the open source software and consulting support to implement features locally. the test bed also would develop new metrics and means of evaluating participatory library services for the use of planners and policy makers. a major deliverable of the test bed, however, would be to model innovations in integrated library systems (ils). the test bed would work with libraries and ils vendors to pilot new technologies and specify new stan­ dards to accelerate ils modernization. the point of the test bed is not to create new ilss, but to make it easy to incorporate innovative technologies into vendor and open source ilss. the location and support model of the test bed are open for the library community to determine. certainly, it could be placed in existing library associations or orga­ nizations. however, it would require the host to be seen as neutral in ils issues, and to be capable of supporting a diverse infrastructure over time. the host organiza­ tion also would need to be a nimble organization, able 32 information technology and libraries | december 200732 information technology and libraries | december 2007 to identify new technical opportunities and implement them quickly. one model that might work is establishing a pooled fund from interested libraries. this pooled fund would support an open source technology infrastructure and a small team of researchers and developers. the team’s activities would be overseen by an advisory panel drawn from contributing members. such a model spreads this investment out into experimentation across a broad col­ laboration and should, ultimately, save libraries time and money. as a result, the time and money that indi­ vidual libraries might spend on isolated or disconnected experiments can be invested in a common effort with greater return. libraries have a chance not only to improve service to their local communities, but to advance the field of par­ ticipatory networks. with their principles, dedication to service, and unique knowledge of infrastructure, libraries are poised not simply to respond to new technologies, but to drive them. by tying technological implementa­ tion, development, and improvement to the mission of facilitating conversations across fields, libraries can gain invaluable visibility and resources. impact and leadership, however, come from a firm and conceptual understanding of libraries’ roles in their communities. the assertion that libraries are an indis­ pensable part of knowledge generation in all sectors pro­ vides a powerful argument to an expanded function of libraries. eventually, blogs, wikis, rss, and ajax all will fade in the continuously dynamic internet environment. however, the concept of participatory networks and con­ versations is durable. ■ acknowledgements the authors would like to thank the following people and groups: ken lavender, for his editing prowess. the

and libraries | december 2018 9 steven k. bowers (sbowers@wayne.edu) is executive director, detroit area library network (dalnet). i played some computers games — stored on data cassette tapes — in the 1980s. that was entertaining, but i never imagined the greater hold that computers would have on the world by the mid-1990s. i can remember getting my first email account in 1993, and looking at information on rudimentary web pages in 1996. i remember my work shifting from an electric typewriter to a bulky personal computer with dial-up internet access. eventually, this new computing technology became a prevalent part of my everyday life. this shift to a computer-driven reality had a major effect on libraries too. i was amazed by the end of the 1990s to be doing research on a university library catalog system connected with other institutions of higher education throughout the region, wondering at the expanded access to, and reach of, information. in my mind, due to computers and the internet, libraries were really connected at that time more than they had ever been. as i prepared this review of what we were writing about in ital in the 1990s, i had some fond memories of the advent of personal computers in my daily life and in the libraries i had access to. as we take a look back, i think it is interesting to see what we were doing then and how it is connected to what we are still working on today. along with the eventual disruption that the internet was to libraries, computers and online access also had the effect of greatly changing how libraries constructed our core research tools, especially the catalog. prior to the 1990s libraries had begun automation projects to move their catalogs to computer-based terminals, creating connections and access that were not previously possible with a card catalog. if we are still complaining about the design and function of the online public access catalog (opac) today, in the early 1990s we were discussing what their design and function should be, in a positive and optimistic way. in some ways it seems hard to recall the discussions of how to format data and display it to users. in other ways it seems like we are still having the same discussions, but our work has become more complex as we continue to restructure library data to become more open and accessible. while we were contemplating the design of online library catalogs, libraries were also discussing the implementation of networking and other information technology infrastructures. nevins and learn examined the changes in hardware, software, and telecommunications at the time and predicted a more affordable cost model with distributed personal computers connected through networks, and enhancing library automation cooperation. 1 they expanded the discussion to include consideration of copyright and intellectual property, security, authorization, and a need for information literacy in the form of user navigation, all key to what we are doing today. beyond catalogs, there was the real adoption of the internet itself. by the early 1990s there was growing enthusiasm for accessing and exploring the internet. 2 this created a need for libraries to learn about the internet and instruct others on how to use it. as late as 1997, however, even search engines were still being introduced and defined, and using the internet or searching the world wide web was still a new concept that was not fully understood by many people. at their the 1990s in review| bowers 10 https://doi.org/10.6017/ital.v37i4.10821 basis, search engines were simply defined as indexing and abstracting databases for the web. 3 it is interesting that library catalogs were developed separately from the development of search engines and we are still trying to get our metadata out of our closed systems and open to the rest of the web. in 1991, kibirige examined the potential impact of this new connectivity on library automation. he posited that “one of the most significant change agents that will pervade all other trends is the establishment and regular use of high-speed, fiber optic communication highways.”4 his article in ital provides a prescient overview of much of what has played out in technology, not just in libraries. he noted the need for disconnected devices to become tools to access full-text information remotely.5 perhaps most important, he noted the need for librarians to become experts in non-library technology, to keep pace with developments outside of the profession. this admonition is still important to keep in mind today. at the time, however, libraries were working on the basics of converting records from online bibliographic utility systems running on mainframes to a more useful format for access on a personal computer, let alone thinking about transforming library metadata into linked data that can be accessed by rest of the internet. so we keep moving forward. later in the decade, libraries began to think about the library catalog as a “one stop shop” for information. in 1997, caswell wrote about new work to integrate local content, digital materials, and electronic resources, all into one search interface. initially the discussion was more technical in nature, but caswell provided an early concept for providing a single access point to all of the content that the library has, print and electronic, which was a step forward from just listing the books in the catalog.6 at the time we were still far away from our current concept of a full discovery system with access to millions of electronic resources that may well surpass the print collections of a library. eventually more discussion developed around the importance of user experience and usability for the design of catalogs and websites. catalogs were examined in parallel with the structure of library metadata, and both were seen as important to the retrievability of library materials. human-machine interaction was starting to be examined on the staff side of systems, and this would eventually become part of examining the public interface usability as well. outlining an agenda for redesigning online catalogs, buckland summarized this new technological development work for libraries by noting that “sooner or later we need to rethink and redesign what is done so that it is not a mechanization of paper but fully exploits the capabilities of the new technology.”7 more exciting, by the end of the 1990s we were seeing usability studies for specific populations and those with accessibility difficulties. systems were in wide enough use that libraries began to examine their usefulness to more audiences. beyond our systems, the technology of our actual collections was changing. new network connectivity combined with new hardware led to new formats for library resources, specifically digital and electronic resources. in 1992, geraci and langschied summarized these changes, stating that “what is new for the 1990s is the complication of a greater variety of electronic format, software, hardware, and network decisions to consider.”8 they also expanded the conversation to include data in all forms, and data sets of various kinds, well beyond traditional library materials. this is an important evolution as libraries worked to shift their operations, identities, and curatorial practices. geraci and langschied defined data by type, including social data, scientific information technology and libraries | month year 11 data, and humanities data. they called most importantly for libraries to include access to this varied data to continue the role of libraries providing access to information, as they cautioned that information seekers were already beginning to bypass libraries and look for such information from other sources. libraries were beginning to lose ground as the gatekeepers of information and needed to shift to providing online access and open data themselves. the early 1990s were an exciting time for preservation, as discussion was moving from converting materials to microforms to digitization. in 1990, lesk compared the two formats and had hope for a promising digital future.9 thank goodness he was on target for sharing resources and creating economical digital copies, even if he did not completely predict the eventual shift to reliance on electronic resources that many research libraries have now made. lesk also noted the importance of text recognition, optical character recognition (ocr), and text formatting in ascii. others focused on digital file formats and the planning and execution of creating digital collections. digitization practices were developing and the need to formalize practice was becom ing evident. the same year, lynn outlined the relationship between digital resources and their original media, highlighting preservation, capture, storage, access, distribution.10 by the late 1990s there were more targeted discussions about the benefits of digitizing resources to provide not only remote access, but access to archival materials specifically. in 1996, alden provided a good primer on everything to consider when doing digitization projects, within budget constraints. 11 by the mid-1990s, karen hunter was excited to extol the promises of the dissemination of information electronically, calling the high performance computing and high speed networking applications act of 1993 “[a] formidable vision and goal. real-time access to everything and a laser printer in every house. the 1990s equivalent to a chicken in every pot.”12 hunter’s article is a good overview of where libraries were at working with electronic publications and online access in the early 1990s. halcyon enssle’s piece on moving reserves to online access opened with a great summary of where much of library access was headed: “the virtual library, libraries without walls, the invisible user . . . these are some of the terms getting used to describe the library of the future . . . .”13 eventually, by the end of the decade we even learned to start tracking how our new online libraries were being used, applying our knowledge of print resource usage to our new online collections. in 1995, laverna saunders had already developed a new definition of what a library was, and how the transformation of libraries from physical warehouses to providing access to online content would affect workflows in libraries. as defined by saunders, “the virtual library is a metaphor for the networked library, consisting of electronic and digital resources, both local and remote.”14 not a bad definition more than 20 years later. saunders asked pertinent questions such as which resources would be best in print vs. online, what print materials should be retained, and which resources and collections libraries should digitize themselves. the broader view provided was that these changes would affect not just collections but the entire operation of libraries. there would still be work to do in libraries, but changes in the work were necessary to address shifting technology and the composition of collections. by the end of the decade there was new work to assess use of electronic resources, extended virtual reference services, and information literacy extending to technology instruction. in 1998, kopp wrote about the promising future of library collaborations. consortia were well established in prior decades and they were seeing a resurgence. kopp noted that just as consortia the 1990s in review| bowers 12 https://doi.org/10.6017/ital.v37i4.10821 had been built around support for new shared utilities in the 1970s and 1980s, in the 1990s they were finding a new purpose in the new networking of the internet and possibilities of greater connectivity and collaborations in the online environment.15 beyond cataloging and automation technology, it is interesting to note that even in the new online environment that was forming in the 1990s, many consortia formed at the time to share print resources. this may have been conversely related to libraries shifting from complete print collections to online holdings that many may have felt were more ephemeral, or maybe money was spent on new technological infrastructures and less on library materials. resource sharing of print materials is still an important part of libraries working together to provide access to information, and since the time that kopp wrote about consortia and growing networked collaborations, there has also been a growing development of sharing electronic resources. a large part of the work of many consortia today revolves around purchasing of electronic resources, but in the late 1990s libraries were just beginning to get into purchasing commercial electronic resources.16 there were lots of ital articles in the 1990s looking at the future of libraries and technology, and some specific articles dedicated to prognostication. in 1991, looking into the future, kenneth e. dowlin shared a vision for public libraries in 2001. he predicted that libraries would still exist but it is noteworthy that at the time the future existence of libraries was questioned by many. dowlin did predict change for libraries, including the confluence of new media formats, computing, and yes, still books. he stated what time has now confirmed: “the public wants them all.”17 he had lots of other interesting ideas as well; his article is worth a second look. another fun take on the future was a special section on science fiction from 1994 considering future possibilities in information technology and access. in one piece, david brin noted, “nobody predicted that the home computer would displace the mega-machine and go on to replace the rifle over the fireplace as freedom’s great emancipator, liberating common citizens as no other technology has since the invention of the plow.”18 an interesting observation, even if the computer has now been replaced by phones in our pockets or other fantastic wearable technologies. by the end of the 1990s, libraries had been greatly transformed by technology. many libraries had automated, workflows continued to adjust in all areas of library work, and most libraries had at least partially incorporated elements of using the internet along with providing computer access to library users. some libraries were already moving through the change from print to electronic library resources. specific web applications and websites were also being developed and used for and by libraries. these eventually have matured into smarter systems that can provide better access to our collections and smarter assessment of our resource usage, for both print and electronic materials. as a whole, the 1990s are an exciting time to review when looking at the intersection of information technology and libraries. as information dissemination moved to an online environment, within and outside of the profession, the future existence of libraries began to be questioned. as we now know, libraries still play an important role in providing access to information. notes 1 kate nevins and larry l. learn, “linked systems: issues and opportunities (or confronting a brave new world),” information technology

20180926 10703 editor president’s message: rebuilding our identity, together bohyun kim information technology and libraries | september 2018 2 bohyun kim (bohyun.kim.ois@gmail.com) is lita president 2018-19 and chief technology officer & associate professor, university of rhode island libraries, kingston, ri. ital is the official journal of lita (library and information technology association), and if you are a reader of the ital journal, it is highly likely that you are a member of lita and/or one who is deeply interested in library technology. it is my pleasure to write this column to update all of you about the exciting discussion that is currently underway in lita and two other ala divisions, alcts (association for library collections and technical services), and llama (library leadership and management association). as many of you know, lita began discussing the potential merger with two other ala divisions, alcts and llama, last year.1 what initially prompted the discussion was the prospect of continuing budget deficits in all three divisions. but the resulting conversation has proved that financial viability is not the entire story of the change that we want to bring about. at the 2018 ala annual conference in new orleans, the three boards of lita, alcts, and llama held a joint meeting open to members and non-members alike to solicit and share our collective thoughts, suggestions, concerns, and hopes about the potential three-division realignment. at this meeting attended by approximately 75 people, participants expressed their support for creating a new division with the following key elements. • retain and build upon the best elements of each division. • embrace the breakdown of silos and positive risk-taking to better collaborate and move our profession forward. • build a strong culture of innovation, energy, and inspiration. • be more transparent, responsive, agile, and less bureaucratic • excel in diversity, equity, and inclusion. • support members in all stages of their careers, those with the least means to travel for in-person participation, in particular. • provide member-driven interactions and good value for the membership fee. these ideas have made it clear that members of all three divisions see the goal of realignment as something much more fundamental than financial sustainability. they have validated the shared belief among the lita, alcts, and llama boards that the ultimate goal of realignment is to create a division that better serves and benefits members, not to simply recover the division’s financial health. while the criteria for the success of a new combined division received almost unanimous endorsement at the meeting, opinions about how to realize such success varied. there were understandable concerns associated with combining three small-sized associations into one large one. for example, how will we reconcile three distinctly different cultures in lita, alcts, and llama? how will the new association ensure itself to be more transparent, responsive, and rebuilding our identity, together | kim 3 https://doi.org/10.6017/ital.v37i3.10703 nimble than the individual divisions prior to the merger? could the larger size of the new division make it more difficult for small groups with special interests to get needed support for their programs? many requested that the leadership of the three divisions provide more specific vision and details. as a group, the leaders of lita, alcts, and llama are committed to hashing out those details. with the aim of providing fuller information about what the new division would look like at the 2019 midwinter conference, we have already formed working groups, one for finances and the other for communication and are currently working to create two more on operations and activities. these four teams will work closely together with the current leadership of lita, alcts, and llama, to prepare the most important information about the proposed new division, so that the boards and the members of three divisions can review and provide feedback for needed adjustments. our goal is to present essential information that will allow the members to vote with confidence on the proposal to form one new division on the ala ballot in the spring of 2019. if the membership vote passes, then we will be taking the proposal to the ala committee on organization for finalization. on this occasion, i would also like to bring to everyone’s attention to an inherent tension between the two ideas that many of us hold as association members regarding alignment. one is that more member involvement in determining alignment-related details at an early stage is essential to the success of the new division. the other is that we can decide whether we will support the new division or not, only after the leadership first presents us with a clear, specific, and detailed picture of what the new division will look like. the problem is that we cannot have both at the same time. as members, if we want to be involved at an early stage of reorganization, we will have to accept that there will be no ready-made set of clear and specific details about the division waiting for us to simply say yes or no. we will be required to work through our collective ideas to decide on those details ourselves. it will be a messy, iterative, and somewhat confusing process for all of us. there is no doubt that this will be hard work for both the lita leadership and lita members. but it is also an amazing opportunity. imagine a new division, where (a) innovative ideas and projects are shared and tested through open conversation and collaboration among library professionals in a variety of functional areas such as systems and technology, metadata and cataloging, and management and administration, (b) frank and inspiring dialogues take place between front-line librarians and administrators about vexing issues and exciting challenges, and (c) new librarians learn the ropes, are supported throughout their careers going through changes in their responsibilities as well as areas of specialization, are mentored to be future leaders, and get to develop the next generation of leaders as they themselves achieve their goals. furthermore, i believe that the process of building this kind of new association from the ground up will be a truly rewarding experience. we had an opportunity to discuss and share our collective hope and vision for the new division at the joint meeting, and that vision is an inspiring one: a division that is member-driven, nimble and responsive, transparent and inclusive, and not afraid to take risks. can we create a new association that breaks down our own silos and builds bridges for better communication and collaboration to move our profession forward? information technology and libraries | september 2018 4 my hope is that we can model and embody the change we want to see, starting in the reorganization process itself. if we want to build a new association that is inclusive, transparent, and nimble, we should be able to build such an association in precisely that manner: inclusively, transparently, and nimbly. if we are successful, our identity as members of this new division will be rebuilt as the very spirit and energy of continuing innovation, experimentation, and collaboration across different functional silos of librarianship, rather than as what we have in our job titles. many lita members and ital readers are leaders in their field and care deeply about the continued success and innovation of lita and ital. i would like to invite all of you to participate in this effort of three-division alignment and to inform and lead our way together. while the boards of three divisions are working on the proposal, there will be multiple calls for member participation. keep your eye out for new updates that will be posted in the ala connect community, “alcts/llama/lita alignment discussion” at https://connect.ala.org/communities/community-home?communitykey=047c1c0e-17b9-45b6a8f6-3c18dc0023f5. all information in this group site is viewable to the public. lita, alcts, and llama members can also join the group, post suggestions and feedback, and subscribe to updates. where would you like lita to be next year, and the year after? let us take lita there, together. endnote 1 andromeda yelton, “president’s message,” information technology and libraries 37, no. 1 (march 19, 2018): 2–3, https://doi.org/10.6017/ital.v37i1.10386. 26 information technology and libraries | june 2008 preparing locally encoded electronic finding aid inventories for union environments: a publishing model for encoded archival description author id (to come) plato l. smith ii this paper will briefly discuss encoded archival description (ead) finding aids, the workflow and process involved in encoding finding aids using ead metadata standard, our institution’s current publishing model for ead finding aids, current ead metadata enhancement, and new developments in our publishing model for ead finding aids at florida state university libraries. for brevity and within the scope of this paper, fsu libraries will be referred to as fsu, electronic ead finding and/ or archival finding aid will be referred as ead or eads, and locally encoded electronic ead finding aids inventories will be referred to as eads @ fsu. n what is an ead finding aid? many scholars, researchers, and learning and scholarly communities are unaware of the existence of rare, historic, and scholarly primary source materials such as inventories, registers, indexes, archival documents, papers, and manuscripts located within institutions’ collections/holdings, particularly special collections and archives. a finding aid—a document providing information on the scope, contents, and locations of collections/ holdings—serves as both an information provider and guide for scholars, researchers, and learning and scholarly communities, directing them to the exact locations of rare, historic, and scholarly primary source materials within institutions’ collections/holdings, particularly noncirculating and rare materials. the development of the finding aid led to the institution of an encoding and markup language that was software/hardware independent, flexible, extensible, and allowed online presentation on the world wide web. in order to provide logical structure, content presentation, and hierarchical navigation, as well as to facilitate internet access of finding aids, the university of california–berkeley library in 1993 initiated a cooperative project that would later give rise to development of the nonproprietary sgml-based, xml-compliant, machine-readable markup language encoding finding aid standard, encoded archival description (ead) document type definition (dtd) (loc, 2006a). thus, an ead finding aid is a finding aid that has been encoded using encoded archival description and which should be validated against an ead dtd. the ead xml that produces the ead finding aid via an extensible style sheet language (xsl) should be checked for well-formed-ness via an xml validator (i.e. xml spy, oxygen, etc.) to ensure proper nesting of ead metadata elements “the ead document type definition (dtd) is a standard for encoding archival finding aids using extensible markup language (xml)” (loc, 2006c). an ead finding aid includes descriptive and generic elements along with attribute tags to provide descriptive information about the finding aid itself, such as title, compiler, compilation date, and the archival material such as collection, record group, series, or container list. florida state university libraries has been creating locally encoded electronic encoded archival description (ead) finding aids using a note tab light text editor template and locally developed xsl style sheets to generate multiple ead manifestations in html, pdf, and xml formats online for over two years. the formal ead encoding descriptions and guidelines are developed with strict adherence to the best practice guidelines for the implementation of ead version 2002 in florida institutions (fcla, 2006), manuscript processing reference manual (altman & nemmers, 2006), and ead version 2002. an ead note tab light template is used to encode findings down to the collection level and create ead xml files. the ead xml files are tranformed through xsl stylesheets to create ead finding aids for select special collections. n ead workflow, processes, and publishing model the certified archivist and staff in special collections and a graduate assistant in the digital library center encode finding aids in ead metadata standard using an ead clip and ead template library in note tab light text editor via data entry input for the various descriptive, administrative, generic elements, and attribute metadata element tags to generate ead xml files. the ead xml files are then checked for validity and well-formed-ness using xml spy 2006. currently, ead finding aids are encoded down to the folder level, but recent florida heritage project 2005–2006 grant funding has allowed selected special collections finding aids to be encoded down to the item level. currently, we use two xsl style sheets, ead2html.xsl and ead2pdf.xsl, to generate html and pdf formats, and simply display the raw xml as part of rendering ead finding aids as html, pdf, and xml and presenting these manifestations to researchers and end users. the ead2html.xsl style sheet used to generate the html versions was developed with specifications such as use of fsu seal, color, and display with input from the special collections department head. the ead2pdf.xsl style sheet used to generate pdf versions uses xsl-fo (formatting plato l. smith ii (psmithii@fsu.edu) is digital initiatives librarian at florida state university libraries, tallahassee. preparing locally encoded electronic finding aid inventories for union environments | smith 27 object), and was also developed with specifications for layout and design input from the special collections department head. the html versions are generated using xml spy home edition with built-in xslt, and the pdf versions are generated using apache formatting object processor (fop) software from the command line. ead finding aids, eads @ fsu, are available in html, pdf, and xml formats (see figure 1). the style sheets used, ead authoring software, and eads @ fsu original site are available via www.lib.fsu.edu/dlmc/dlc/ findingaids. n enriching ead metadata as ead standards and developments in the archival community advance, we had to begin a way of enriching our ead metadata to prepare our locally encoded ead finding aids for future union catalog searching and opac access. the first step toward enriching the metadata of our ead finding aids was to use rlg ead report card (oclc, 2008) on one of our ead finding aids. the test resulted in the display of missing required (req), mandatory (m), mandatory if applicable (ma), recommended (rec), optional (opt), and encoding analogs (relatedencoding and encodinganalog attributes) metadata elements (see figure 2). the second test involved reference online archive of california best practices guidelines (oac bpg), specifically appendix b (cdl, 2005, ¶ 2), to create a formal public identifier (fpi) for our ead finding aids and make the ead fpis describing archives content standards (dacs)–compliant. this second test resulted in the creation of our very first dacs– compliant ead formal public identifier. example: <eadid countrycode=“us” identifier=“mss2003004” mainagencycode=“ftasu” publicid=“-//florida state university::strozier library::special collections//text (us::ftasu::ftasu2003004:: bernard f. sliger collection)//en”>ftasu2003004. xml</eadid> the rlg ead report card and appendix b of oac bpg together helped us modify our ead finding aid encoding template and workflow to enrich the ead document identifier <did> metadata tag element, include missing mandatory ead metadata elements, and develop fpis for all of our ead finding aids. prior to recent new developments in the publishing model of ead finding aids at fsu libraries, the ead finding aids in our eads @ fsu inventories could not be easily found using traditional web search engines, were part of the so-called “deep web,” (prom & habing, 2002) and were “unidimensional in that they [were] based upon the assumption that there [was] an object in a library and there [was] a descriptive surrogate for that object, the cataloging record” (hensen, 1999). ead finding aids in our eads @ fsu inventories did not have a descriptive surrogate catalog record and lacked the relevant related encoding and analog metadata elements within the ead metadata with which to facilitate “metadata crosswalks”—mapping one metadata standard with another metadata standard to facilitate crosssearching. “to make the metadata in ead instance as robust as possible, and to allow for crosswalks to other encoding schemes, we mandate the inclusion of the relatedencoding and encodinganalog attributes in both the <eadheader> and <archdesc> segments” (meissner, et al., 2002). incorporating an ead quality checking tool such as rlg bpg and ead compliance such as dacs when figure 1. ead finding aids in html, pdf, and xml format figure 2. rlg ead report card of xml ead file 28 information technology and libraries | june 2008 authoring eads, will assist in improving ead encoding and ead finding aids publishing model. n some key issues with creating and managing ead finding aids one of the major issues with creating and managing ead finding aids is the set of rules used for describing papers, manuscripts, and archival documents. the former set of rules used for providing consistent descriptions and anglo-american cataloging rules (aacr) bibliographic catalog compliance for papers, manuscripts, and archival documents down to collection level was archives, personal papers, and manuscripts (appm), which was complied by steven l. hensen and published by the library of congress in 1983. however, the need for more description granularity down to the item level, enhanced bibliographic catalog specificity, marc and ead metadata standards implementations and metadata standards crosswalks, and inclusion of descriptors of archival material types beyond personal papers and manuscripts prompted the development of describing archives: a content standard (dacs), published in 2004 with the second edition published in 2007. “dacs [u.s. implementation of international standard for the description of archival materials and their creators] is an output-neutral set of rules for describing archives, personal papers, and manuscripts collections, and can be applied to all material types ”(pearce-moses, 2005). some international standards for describing archival materials are general international standard archival description isad(g) and international standard archival authority record for corporate bodies, persons, and families [isaar(cpf)]. other issues with creating and managing ead finding aids include (list not exhaustive): 1. online presentation of finding aids 2. exposing finding aids electronically for searching 3. provision of a search interface to search finding aids 4. online public access catalog record (marc) and link to finding aids 5. finding aids linked to digitized content of collections eads @ fsu exist in html for online presentation, pdf for printing, and xml for exporting, which allow researchers greater flexibility and options in the information-gathering and research processes and have improved the way archivists communicated guides to archival collections with researchers as opposed to paper finding aids physically housed within institutions. eads @ fsu have existed online in html, pdf, and xml formats for two years in a static html document and then moved to drupal (mysql database with php) for about one year, which improved online maintenance but not researcher functionality. however, the purchase and upgrade of a digital content management system marked a huge advancement in the development of our ead finding aids implementation and thus resolutions to issues numbers 1–3. researchers now have a single-point search interface to search eads @ fsu across all our digital collections/ institutional repository (see figure 3); the ability to search within the finding aids via full-text indexing of pdfs; the option of brief (thumbnails with ead, htm, pdf, and xml manifestation icons), table (title, creator, and identifier), and full (complete ead finding aid dc record with manifestations) views of search results, which provides different levels of exposures of ead finding aids; and the ability to save/e-mail search results. future initiatives are underway to enhance eads @ fsu implementation via the creation of ead marc records through dublin core to marc metadata crosswalk, to deep link to ead finding aids via 856 field in marc records, and to begin digitizing and linking to ead finding aids archival content via digital archival object <dao> ead element. <dao> is “linking element that uses the attributes entityref or href to connect the finding aid information to electronic representations of the described materials. the <dao> and <daogrp> elements allow the content of an archival collection or record figure 3. online search gui for ead finding aids and digital collections within ir preparing locally encoded electronic finding aid inventories for union environments | smith 29 group to be incorporated in the finding aid” (loc, 2006b). we have opted to create basic dublin core records of ead finding aids based on the information in the ead finding aids descriptive summary (front matter) first and then crosswalk to marc, but are cognizant that this current workflow is subject to change in the pursuit of advancement. however, we are seeking ways to improve the ead workflow and ead marc record creation through more communication and future collaboration with the fsu libraries cataloging department. n number of finding aids and percent of eads @ fsu as of february 16, 2006, we had 700 collections with finding aids in which 220 finding aids are electronic and encoded in html (31 percent of total finding aids). from the 220 electronic finding aids, 60 are available as html, pdf, and xml finding aids (20 percent of electronic finding aids are eads @ fsu). however, we currently have 63 ead finding aids available online in html, pdf, and xml formats. n new developments in publishing eads @ fsu current eads @ fsu include the recommendations from test 1 and test 2 (rlg bpg and dacs compliance) which were discussed earlier and the digital content management system (i.e. digitool) creates a descriptive digital surrogate of the ead objects in the form of brief and basic dublin core metadata records for each ead finding aid along with multiple ead manifestations (see figure 4). we have successfully built and launched our first new digital collection, fsu special collections ead inventories, in digitool 3.0 as part of fsu libraries dlc digital repository (http://digitool3.lib.fsu.edu/r/), a relational database digital content management system (dcms). digitool has an oracle 9i relational database management system backend, searchable web-based gui, a default ead style sheet that allows full-text searching of eads, supports marc, dc, mets metadata standards, jpeg2000 (built in tools for images and thumbnails) as well as z39.50 and oai protocols which will enable resource discovery and exposing of eads @ fsu. you can visit fsu special collections ead finding aids inventories at http://digitool3.lib.fsu.edu/r/? func=collections-result&collection_id=1076. n national, international, and regional aggregation of finding aids initiatives rlg’s archivegrid (http://archivegrid.org/web/index. jsp) is an international, cross-institutional search constituting the aggregation of primary source archival materials of more than 2,500 research libraries,

(the ital editor and editorial board report to the publications committee.) after six months, the electronic issues will be open to all, not restricted to members and subscribers. put simply, if you are a member or subscriber reading this issue in print, you may also read it and volume 25, number 1 (the march 2006 issue) on the web. when volume 25, number 3 is published in september 2006, the march issue on the web will be open for anyone to read. when the december issue is published, this june e-issue will be open to all. the web versions are to be published in both pdf and html versions. most ital articles now include urls. readers will be able to link to them. most figures and graphs submitted by authors are in color. from now on, these will be available to the readers of the e-copies. ala publishing allows authors to submit their articles to institutional repositories, and many authors now do so. authors will retain this option. some articles have been posted on other

versions and to allow open access after six months were not made lightly. the lita board members carried on extensive electronic discussions among themselves and with nancy colyar, chair of the publications committee, and me. lita president pat mullin’s summary of those discussions was more than ten single-spaced pages. nancy and i also attended a meeting of the board in san antonio. publications and memberships are two chief sources of revenue for almost all professional associations. in two surveys in the past ten years, lita members have indicated they considered ital to be their most important membership benefit. lita membership fell this year, probably because of the recent dues increases by other divisions of ala. this decline was anticipated by lita’s leadership. i think both the ital editorial board and the lita leadership would love to take the additional pioneering step of making our journal a full open-access publication. however, legitimate concern was expressed that opening access after six months might lead to both a decrease in members and subscribers. a significant number of lita leaders said that their membership was based on lita programs, participation, and interaction with colleagues, not just ital. i hope that all lita members feel the same. i further hope that lita members will do everything they can to discourage their libraries from canceling their subscriptions. our financial health would be enhanced if all lita members took two other steps: participating in writing and encouraging the writing of significant articles, and encouraging your many library technology vendors to advertise in ital. fred kilgour and the other founders of our division were library information technology (it) pioneers. fred’s leadership helped make jola and now ital vital reading for library it professionals. i believe that by celebrating the lita/ital anniversaries with a reconfirmation of our practice of publishing articles of the highest quality and by making ital more accessible through electronic publication, we are reaffirming the scholarly and professional commitments first made by fred kilgour and his isad colleagues such a short

mailto:varnum@umich.edu editorial board changes in this issue call for pllw contributions index blending is the process of database development whereby various components are merged and refined to create a single encompassing source of information. once a research need is determined for a given area of study, existing resources are examined for value and possible contribution to the end product. index blending focuses on the quality of bibliographic records as the primary factor with the addition of full text to enhance the end user’s research experience as an added convenience. key examples of the process of index blending involve the fields of communication and mass media, hospitality and tourism, as well as computers and applied sciences. when academia, vendors, subject experts, lexicographers, and other contributors are brought together through the various factors associated with index blending, relevant discipline-specific research may be greatly enhanced. a s consumers, when we set out to make a purchase, we want the utmost in quality, and when applica­ ble, quantity, and of course all of the other ”appeal” factors that might be associated with a given product or service. these factors may include any number of catego­ ries, not the least of which is price. in other words, let it suffice to say that, as buyers, we want to have our cake and eat it, too. but how often is this a realistic approach to evaluating a given item for purchase? we first must decide what is important to us, decipher the order of this importance as we see it, and evaluate our options. wouldn’t it be much easier if one product in every situ­ ation had all of the factors that we deem important, and the appropriate price to go along with it? according to veliyath and fitzgerald in an article published in competitiveness review, firms can either posi­ tion themselves at the high end, offering higher quality at higher prices, or at the lower end, offering lower quality at a lower price (or anywhere in­between on the continuum of constant value for customers). customers, however, want more of what they value, such as convenience, speed, state­of­the­art design, quality, etc. competitors then try to differentiate themselves from their rivals along the same line of constant value, either by offering a higher quality at the same price or the same quality at a lower price (thereby increasing value for the customer).1 as such, and using a common example, is it possible to have the handling of a bmw sports car, the luxurious ride of a cadillac, the passenger space of a winnebago, the cargo space of an oversized pick­up truck, all for the price of an economy car? it’s doubtful. but through recent developments in the electronic research database market­ place, and a process known as “index blending,” we may be closer than ever to this ideal formula when it comes to web­based reference resources for academic libraries. the phrase “index blending” is used here to describe an original concept/methodology initiated by ebsco publishing (ebsco). this is not to say that ebsco is the first vendor ever to have combined resources to create a new product, but to the authors’ best knowledge, no other vendor has pursued the “blending” of resources to the same extent and with such a strong guiding directive as ebsco has. index blending is the combining of niche indexes and other important components to create a single defini­ tive index for a particular discipline. as vendors seek to offer the most powerful research database for a given area of study, the pieces may come together through a combination of existing resources and proprietary development. in other words, in order to refine the tools used for research in a discipline, existing resources may be combined, fleshed out, further expanded upon, and enhanced to culminate in the archetypical index for the particular discipline. perhaps this represents the solution to the dilemma that “database choices become increas­ ingly complex when multiple sources exist that cover the same discipline.”2 the idea may seem elementary, but the process, however, can be arduous. processes involved with index blending expand upon the basic development stages asso­ ciated with creating a research database from “scratch,” coupled with an increase in applicable factors, which become evident when several existing and emerging resources are involved and subsequently interwoven. as is always the case, the first step to building a solution is to identify the problem and/or the need. in database devel­ opment, this is, in a nutshell, pinpointing a subject area of research that is lacking a corresponding definitive index, and where study patterns and research interest dictate a need for such a resource. this involves not only conduct­ ing surveys and engaging in discussion with advisory boards, librarians, subject experts, users, etc., but also taking a close look at the research resources that are cur­ rently available to determine value. because the process begins with the fact that there is a problem (no definitive index for the particular area in question), the idea is to understand the strengths of available resources, as well as to identify weaknesses. through this research process, vendors can further identify independent elements of each resource that may index blending | brooks and herrick 27 index blending: enabling the development of definitive, discipline-specific resources sam brooks and mark herrick sam brooks

publishing. 2� information technology and libraries | june 20072� information technology and libraries | june 2007 provide significant benefit or value, as well as pinpoint the additional important pieces that are not represented in any of the available resources. in both cases (available and not available), these elements may represent various aspects associated with a research index such as content coverage (both current and backfile), quality of indexing and abstracts, software/search functionality, thesauri, etc. once the identification and research has taken place, vendors should have the necessary knowledge to proceed to the production phase. figure 1 helps to illustrate how the index blending process can help to develop a new database that fuses together the strengths of existing resources while simul­ taneously compensating for any individual weaknesses that they may have. if value is attributed to currently available databases, then, if appropriate, database acquisition may come into play. this is often a critical phase of the process, and may involve the acquisition of more than a single index. however, the desire by a vendor to acquire a given resource is based on several motivating factors, including the qual­ ity of the database as a whole, the depth and breadth of its coverage, and at times, the extreme quality of an intricate aspect of a database, which will eventually be said data­ base’s contribution to the process of index blending, thus representing its “mark” on the final product. because there is no authoritative resource available for a given subject area does not mean necessarily that certain aspects of existing resources are not of utmost quality. hence, utilizing strengths of existing resources makes sense so as to not “reinvent the wheel” when applicable. in a journal of academic librarianship article discussing the research environment in libraries and the simultaneous utilization of existing library resources, similar principles to those used in index blending are apparent. “properly combining library resources to func­ tion collectively as a cohesive, efficient unit is the basis of information integration.”3 similar themes to those asso­ ciated with information integration run through index blending. this is attributed largely to the fact that the basic goal of each is to enable the extraction and utiliza­ tion of essential material pertinent to specific research so as to enhance the overall research process. n the process of index blending an example an interesting example of index blending utilized for a major area of study is in the case of communication and mass media. an article in searcher outlined the develop­ ment process and release of the database, communication & mass media complete, which may be the quintessential instance of the power brought about through index blending. in the article, the author first identifies the problem/need as such: when a communication studies student approaches my reference desk, it can take a few moments before i choose a database to search. why the delay? well, to be perfectly blunt, the communication studies literature is all over the place. if the question relates to an aspect of the communications industry, i will often begin with a business database. if the question concerns the effects of media violence on children, i may choose to search one or more of the following: comabstracts, psychinfo [sic], sociological abstracts, eric, and even a few large aggregators, such as wilsonweb’s omnifile and ebsco’s academic search premier. in addition, there is the question of finding a single database that covers the communication science and disorders field and the more mass media­focused communication studies field. the result has been a searching strategy that relies on consulting multiple databases—a strategy that may not please impatient or inexperienced patrons. the need for such an assortment of databases is symptomatic of the discipline. the field of com­ munication studies is extremely interdisciplinary. the discipline’s roots began in the study of rhetoric and journalism and now encompass subjects ranging from political communication to film studies to advertising to journalism to communication disorders to digital convergence and to every manner of media. the dis­ cipline has strong roots in the social sciences, but also draws heavily on the humanities and the sciences. as some have put it, there is an aspect of communication studies in every discipline. this leaves librarians with the difficult task of finding a single database that cov­ ers this wide­ranging discipline. enter ebsco’s new communication & mass media complete database.4figure 1. the index blending process public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 2�index blending | brooks and herrick 2� this overview of the need for a comprehensive resource in areas related to communication and mass media is indicative of the type of information that vendors must extract when deciding their course of action for creat­ ing (or not creating) a database to meet such needs. in this instance, the need became apparent to ebsco upon conducting investigative research in this direction. there were certainly important, quality resources available cov­ ering some of the subject areas and subdisciplines, but not a single, all­encompassing resource. hence, the table was set to move forward and begin the process of data­ base development using the process of index blending. once the need for a comprehensive communication and mass media database was established, ebsco began the phases of looking closely at available resources and gathering specific important details about what was required to develop such a database. in order to under­ stand the finer details and make appropriate forward progress in formulating an index for a given research area, a dedicated group of subject experts (advisory board, indexers, lexicographers, etc.) must be estab­ lished. in addition, aggregators must develop appro­ priate relationships and key partnerships. in the case of the database communication & mass media complete, ebsco worked diligently to assemble a panel of experts to provide direction. often, suggestions made by advi­ sory board members ultimately led to larger organiza­ tional partnerships. the first of ebsco’s major partnerships for the benefit of the development of communication & mass media complete was with the national communication association (nca). nca is the oldest and largest national organization to promote communication schol­ arship and education. founded in 1914, the nca is a nonprofit organization of approximately 7,100 educa­ tors, practitioners, and students who work and reside in every u.s. state and more than twenty countries. the purpose of the association is to promote study, criti­ cism, research, teaching, and application of the artistic, humanistic, and scientific principles of communica­ tion. nca is a scholarly society and, as such, works to enhance the research, teaching, and service produced by its members on topics of both intellectual and social significance. staff at the nca national office follows trends in national research, teaching, and service pri­ orities. it relays those opportunities to its members and represents the academic discipline of communication in those national efforts.5 in addition to providing insight and advice into the areas associated with communication and mass media, nca found in ebsco an ideal partner to further the tremendous efforts the organization had put into its database, commsearch. commsearch, in its original form, was a scholarly communication database with deep, archival coverage of the journals of the nca and other major journals in the field of communication studies. the database provided bibliographic and keyword references to twenty­six journals in communication studies with coverage extending to the inaugural issue of each—some from as far back as the early decades of the twentieth century. the database also included cover­to­cover indexing of the nca’s first six journals (from their first editions to the present) and author­sup­ plied abstracts from their earliest appearance in nca journals. as ebsco’s goals were in line with the nca in terms of improving scholarly research in areas sur­ rounding communication as well as enhancing the dis­ semination of applicable materials, a partnership was formed, and ebsco acquired commsearch. the com­ pany acquired this database with the intent to enhance the collection through content additions such that it would take residence immediately as a core component of communication & mass media complete. the second major database acquisition came about similarly to the commsearch arrangement; only this time, ebsco worked closely with penn state university, the developers of a database called mass media articles index. created by jack pontius and maintained by the penn state libraries since 1984, mass media articles index provided citation coverage for over forty thousand articles on mass media published in over sixty research journals, as well as major journalism reviews, recent encyclopedias, and handbooks in the area of communications studies. this database, which was once a stand­alone research tool, is a good example of how a good­quality resource can arise out of the passion and unique vision of an individual, yet never fully develop into its full potential due to a lack of funding, dedicated staff, and experience in database publishing. seeing the incredible potential of mass media articles index, ebsco earmarked this database as the sec­ ond major component in its larger communication and mass media product. as mentioned, the basic idea with index blending is to pinpoint the best and most important aspects of each database to carry forward into the final product. it is at this point that difficulty typically arises in the normalization of data. once core database components are determined, a vendor ’s expertise in building data­ bases, standardizing entries, etc., comes to the forefront. furthermore, because another basic ingredient to the process of index blending revolves around additional material included by the database developer, that aggre­ gator has the burden of taking the core building blocks of the database and elevating these raw materials to the point where their combination and refinement become the desired end result—a definitive, cohesive index to research in the subject area. with this in mind, ebsco carefully selected the indexing components of each resource that were essen­ tial to carry forward and substantially expanded the 30 information technology and libraries | june 200730 information technology and libraries | june 2007 abstracting and indexing coverage of appropriate journals in commsearch and mass media articles index. the company also added indexing and abstracts for many more of the important titles in the communication and mass media fields that were not covered by these databases. through its initial research, ebsco gained a thorough knowledge of which journals and other content sources were not covered by the two acquired databases, and worked to provide coverage for those missing sources. as such, the idea with this database was to cover all appropriate, qual­ ity titles indexed in all other currently avail­ able communication and mass media­specific databases combined, as well as other important journals not previously covered by any such database. further still, the company took the database to new levels through the creation and deployment of features such as searchable cited references and index browsing. figure 2 provides a visual interpretation of the elements associated with this particular example of index blending. often academic librarians consider aggre­ gated full­text databases as a means for access­ ing full­text information quickly, but with a negative outlook toward the quality of the indexing included in these databases. however, it is ebsco’s intention to create first and fore­ most a powerful index, such that any full text included is that much easier to locate and utilize. according to cleveland and cleveland in the book introduction to indexing and abstracting, 3rd ed., “in any retrieval system, success or failure depends on the adequacy of the indexing and the related search­ ing procedures.”6 ebsco wholeheartedly agrees with this statement. and though the company is the leader in providing full­text databases, it continues to raise the bar for these databases through not only constantly increasing the quality and quantity of full text, but also by enhancing indexing, abstracts, and associated search functionality. a database may provide the greatest collection of full text, yet it is still only as good as its underlying indexing framework that guides users to the appropriate content. index blending allows for this ideal because the development of the indexing takes place at the onset as the primary objective, and full text may be included at a later stage. this is precisely the case with ebsco’s communication/communications database where the first iteration of the collection (communication & mass media index) did not include full text, and the complete (full­text version) was soon to follow. thus, in the case of communication & mass media complete, once the core elements for the index were in place, refined, and normalized, ebsco moved forward in the area of full­text content. in addition to the inclu­ sion of full text for all of the nca journals, which david oldenkamp refers to as “heavyweights in communication studies,” ebsco included full­text coverage for nearly 230 titles. according to oldenkamp, as of april 2004, the competing database with the next largest number of publications covered in full text included only sixteen full­text titles.7 though index blending is not the traditional way in which to build a database, and may actually be the most labor­intensive way in which to proceed, the end results can be remarkable when done properly. using this process, “ebsco has managed to create the largest and most comprehensive database serving the needs of communication studies scholars, faculty, students, and librarians.”8 in addition, a review published in the charleston advisor determined that “ebsco has brought together two reliable but atrophied resources and refreshed them with new search capabilities and added content, such as abstracts. these have been combined with a healthy dose of ‘not indexed anywhere’ new titles and interdisciplinary sources to create a comprehensive figure 2. indexing components of communication & mass media complete public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 31index blending | brooks and herrick 31 resource that will satisfy the needs of students, faculty, and researchers.”9 n another example of index blending hospitality & tourism index index blending is a concept as much as it is a process and a means to an end. much like applying a particular theory to a number of different instances, index blending is inter­disciplinary in application. thus, the area of com­ munication/communications as described previously, is simply an example of practical implementation of this concept, and a particular way in which the process was approached given the specific elements involved. another discipline to which index blending has been applied is the niche areas related to hospitality and tourism. according to professor vivienne sario, director of travel and tourism at community college of southern nevada, “on a global basis the hospitality and tourism industry employs more than 10 percent of the worldwide workforce. it contributes over $4 trillion in gross global output. this means travel and tourism is the world’s largest industry.”10 though still considered (perhaps incorrectly) a “niche” area of study, the number of hospitality and tourism programs supported in colleges and universities around the globe has also increased to the point where dozens and dozens of twoand four-year academic institutions provide related courses of study. from a business perspective, in order to justify the amount of resources that would inevitably be expended to develop a high-end, comprehensive database, the basic criteria needed for database development must first be in place. considering the economic vastness of the hospitality and tourism industry, the interest and research need is quite apparent. if there is at least one clearly definitive academic resource covering the subject area, in all likelihood, the decision would be made to cease exploration and development in that area. contrarily, when ebsco conducted exhaustive research to determine the need for a new index to literature in the areas of hospitality and tourism, the unanimous conclusion was to move forward in the development of a product that would go above and beyond the level of the existing resources. this is not to say that quality was not inherent in some of the existing resources. in actuality, the fact that there were already quality (albeit perhaps incomplete) resources available, paved the way for utilizing principles of index blending in the development of a more comprehensive resource. the first element of what was to become ebsco’s hospitality & tourism index was purdue university’s lodging, restaurant, & tourism index (lrti). as an indi­ cator of the level of emphasis attributed to this subject area by the university, purdue’s hospitality and tourism management undergraduate program was ranked num­ ber one nationally by a survey published in the journal of hospitality & tourism education.11 a previous survey conducted by the same journal used a different method­ ology and sample, but still ranked purdue’s hospitality and tourism management (htm) program number one in the nation.12 to provide insight into the purdue htm program, the origins and history of lrti, the need for a compre­ hensive database, and the university’s decision to work with ebsco, questions were asked of two prominent purdue faculty members: raphael kavanaugh, head, hospitality and tourism management department, and priscilla geahigan, head, consumer and family sciences library. the following is taken from e­mail cor­ respondence among one of the authors (sam brooks), kavanaugh, and geahigan: brooks: how long has purdue offered a hospitality & tourism management program? kavanaugh: the program began in 1928 as the department of institutional management. brooks: when and why did purdue decide to create the lodging restaurant & tourism index (lrti)? kavanaugh: to fill a serious void of access to relevant research conducted related to the industry. geahigan: before 1990 coverage of the hospitality industry within business indexes and databases was limited. to meet the needs of researchers and students, purdue’s restaurant, hotel, institutional, and tourism management department, an in­house indexing project, started in the purdue consumer and family sciences library in 1977. citations of articles from scholarly and trade journals were entered on index cards, filed by subject headings. in 1985 the project became more for­ malized and migrated into partnership with a few other academic institutions. a printed index titled lodging and restaurant index started. in 1987, purdue became the sole producer of the index. in 1995, the index was renamed the lodging, restaurant, and tourism index (lrti), with expanded scope and coverage. over the years, data diskettes and cd­rom formats were added to the printed version. brooks: how important are “niche” or subject­specific databases to support research in a given area such as h&t? geahigan: in contrast to earlier years, students can now get their information from a multitude of databases and 32 information technology and libraries | june 200732 information technology and libraries | june 2007 venues. at purdue, we have databases that cover all aspects of business and management. undergraduate students often get confused and impatient at the large number of databases offered. a subject specific database like hti gives them a place to start without feeling lost. brooks: why did purdue decide to partner with ebsco, and subsequently merge lrti in the larger hospitality & tourism index (hti)? geahigan: we realized that we do not have the resources to support a database that measures up to industry technology standards and have long decided to look for a company to take over lrti. ebsco’s offer was attrac­ tive to purdue because of their willingness to assume future indexing of the lrti journals. in addition, many purdue students are already familiar with the ebsco interface because we have numerous other ebsco hosted databases. we are pleased that lrti became the foundation of ebsco’s building of hti.13 the second foundational component of the database also came about through acquisition from an academic institution. articles in hospitality and tourism was copro­ duced by oxford brookes university and the university of surrey. bournemouth university was also a source of data for this database between the years of 1988 and 1998. this database provided details of more than forty­six thousand english­language articles selected from more than 330 relevant academic and trade journals published worldwide from 1984 to 2003.14 rounding out the list of three existing resources that were acquired by ebsco, the hospitality database (acquired from the original developers at cornell university) was also assimilated into the new hospitality and tourism database. the hospitality database evolved from the print publication bibliography of hotel management and related subjects that was originally established in the 1950s by blanche fickle, the first director of the library at cornell university’s school of hotel administration.15 this database, founded on the vision of ms. fickle, would serve as a core resource for ebsco’s new hospitality & tourism index by providing it with a foundation of quality indexing for journals related to the study of hotel adminis­ tration and management. ebsco completed the initial development of its hospitality and tourism database by reviewing applicable subscription statistics maintained by its sister company, ebsco subscription services, in order to locate other publications relevant to the various subdisciplines of hospitality and tour­ ism. any such publications that were not already indexed by the other three existing resources were targeted for inclusion in the new hospitality & tourism index. figure 3 provides a visual interpretation of the ele­ ments associated with this particular example of index blending. following the initial release of hospitality & tourism index, in order to provide an even more inclusive research experience, ebsco proceeded to develop and release a full­text version of this resource entitled hospitality & tourism complete. this new variant of the database offers users the same indexing infrastructure as hospitality & tourism index, as well as provides the additional benefit of immediate access to relevant full­text content. while the availability of full text is certainly of immense value, it is still the quality of underlying indexing that allows this database to be regarded as truly innovative. in fact, this same perspective was echoed in a recent review in choice where the author states that “hospitality & tourism complete indexes its specialized subject area bet­ ter than any other product currently available.”16 n the whole is greater than the sum of its parts the process of index blending not only brings together content from a variety of resources, it also has the power to increase the research value of that same content. by combining such content under the umbrella of a single comprehensive database, pertinent information can now be more efficiently accessed and cross­referenced with other relevant content. previously, the same body of information could only be explored via a highly ineffec­ tive, piecemeal research process. one last example that demonstrates this potential increase in research value is found in the computers & figure 3. indexing components of hospitality & tourism complete public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 33index blending | brooks and herrick 33 applied sciences complete database. this resource was shaped through the acquisition and merger of three distinct indexes—computer science index (csi), internet & personal computing abstracts (ipca), and information science & technology abstracts (ista)—and rounded out with addi­ tional indexed content relevant to the larger discipline. this resulted in a total of 1,100 active journals indexed back as far as 1965. then, after two years of dedicated licensing work with pub­ lishers, full text for more than 570 of those titles was added to provide more direct access to such content for researchers. figure 4 illustrates how the various subject areas (unique and shared) covered by the three original databases were merged together in the blending process. from this diagram, it is apparent that the original three databases were already quality resources in their own right and adequately rep­ resented their respective subject areas. however, it should also be apparent that, through the pro­ cess of index blending, the value of the original databases has been enhanced via the fusion of their unique, yet complementary content into a single comprehensive resource. n conclusion though the above examples of communication & mass media complete, hospitality & tourism index, and computers & applied sciences complete represent only three of sev­ eral subject­specific databases culminating from the process of index blending, most database producers (including ebsco) would likely agree that this is not a common procedure for database development. however, the knowledge that a company derives from the pro­ cess often has a significant impact on the company’s other, “nonblended” databases. index blending typically requires a high degree of refinement in order to be fully successful, so when a company engages in this rigorous developmental process, the newfound experience and expertise gained from it may spill over into the com­ pany’s other database initiatives. end users may notice improved indexing, abstracts, and other valuable com­ ponents that are now included in other more established full­text resources from the same vendor. databases that were once viewed simply as “aggregated full­text data­ bases” may be looked upon in a different light after the company adopts the process of index blending for other, unrelated database projects. though these databases may still provide easy access to an abundance of full­text content, they may also now be considered the definitive index for their respective subject area(s). therefore, when a company implements the practice of index blending for some of its products, the resulting effects are two­ fold. the databases created directly as a result of the index blending process are the first to benefit, and the company’s other databases (including those with full text) may also benefit from index blending in an indirect manner. in the end, however, the success of any index blending initiative is measured by the level of benefit that it provides to applicable researchers and other users of the resulting databases. references 1. rajaram veliyath and elizabeth fitzgerald, “firm capabil­ ities, business

(theovanveen@gmail.com) is researcher (retired), koninklijke bibliotheek. abstract library catalogues may be connected to the linked data cloud through various types of thesauri. for name authority thesauri in particular i would like to suggest a fundamental break with the current distributed linked data paradigm: to make a transition from a multitude of different identifiers to using a single, universal identifier for all relevant named entities, in the form of the wikidata identifier. wikidata (https://wikidata.org) seems to be evolving into a major authority hub that is lowering barriers to access the web of data for everyone. using the wikidata identifier of notable entities as a common identifier for connecting resources has significant benefits compared to traversing the ever-growing linked data cloud. when the use of wikidata reaches a critical mass, for some institutions, wikidata could even serve as an authority control mechanism. introduction library catalogs, at national as well as institutional levels, make use of thesauri for authority control of named entities, such as persons, locations, and events. authority records in thesauri contain information to distinguish between entities with the same name, combine pseudonyms and name variants for a single entity, and offer additional contextual information. links to a thesaurus from within a catalog often take the form of an authority control number, and serve as identifiers for an entity within the scope of the catalog. authority records in a catalog can be part of the linked data cloud when including links to thesauri such as viaf (https://viaf.org/), isni (http://www.isni.org/), or orcid (https://orcid.org/). however, using different identifier systems can lead to having many identifiers for a single entity. a single identifier system, not restricted to the library world and bibliographic metadata, could facilitate globally unique identifiers for each authority and therefore improve discovery of resources within a catalog. the need for reconciliation of identifiers has been pointed out before.1 what is now being suggested is to use the wikidata identifier as “the” identifier. wikidata is not domain specific, has a large user community, and offers appropriate apis for linking to its data. it provides access to a wealth of entity properties, it links to more than 2,000 other knowledge bases, it is used by google, and the number of organisations that link to wikidata is quantifiably growing with tremendous speed.2 the idea of using wikidata as an authority linking hub was recently proposed by joachim neubert.3 but why not go one step further and bring the wikidata identifier to the surface directly as “the” resource identifier, or official authority record? this has been argued before and the implications of this argument will be considered in more detail in the remainder of this article. 4 information technology and libraries | june 2019 73 figure 1. from linking everything to everything to linking directly to wikidata. figure 1 illustrates the differences between a few possible situations that should be distinguished. on the left, the “everything links to everything” situation shows wikidata as one of the many hubs in the linked data cloud. in the middle, the “wikidata as authority hub” situation is shown, where name authorities are linked to wikidata. on the right is the arrangement proposed in this article, where library systems and other systems for which this may apply share wikidata as a common identifier mechanism. of course, there is a need for systems that feed wikidata with trusted information and provide wikidata with a backlink to a rich resource description for entities. in practice, however, many backlinks do not provide rich additional information and in such cases a direct link to wikidata would be sufficient for the identification of entities. figure 2 shows these two situations and other possible variations by means of dashed lines, i.e. systems that feed wikidata, but use the wikidata identifier as resource identifier for the outside world vs. systems that link directly to wikidata, but keep a local thesaurus for administrative purposes. it is certainly not the intention to encourage institutions to give up their own resource descriptions or resource identifiers locally, especially not when they are an original or rich source of information about an entity. a distinction can be made between the url of the description of an entity and the url of the entity itself. when following the url of a real-world entity in a browser, it is good practice to redirect to the corresponding description of the entity. this is known as the “httprange-14” issue.5 this article will not go into any detail about this distinction other than to note that it makes sense to have a single global identifier for an entity while accepting different descriptions of that entity linked from various sources. wikidata | van veen 74 https://doi.org/10.6017/ital.v38i2.10886 figure 2. feeding properties connecting collections to wikidata (left) and direct linking to wikidata using resource identifier (right). the dashed lines show additional connecting possibilities. the motivating use case the idea of using the wikidata identifier as a universal identifier was born at the research department of the national library of the netherlands (kb) while working on a project aimed at automatically enriching newspaper articles with links to knowledge bases for named entities occurring in the text.6 these links include the wikidata identifier and, where available, the dutch and english dbpedia (http://dbpedia.org) identifiers, the viaf number, the geonames number (http://geonames.org), the kb thesaurus record number, and the identifier used by the parliamentary documentation centre (https://www.parlementairdocumentatiecentrum.nl/). the identifying parts of these links are indexed along with the article text in order to enable semantic search, including search based on wikidata properties. for demonstration purposes the enriched “newspapers+” collection was made available through the kb research portal, which gives access to most of the regular kb collections (figure 3). 7 in the newspaper project, linked named entities in search results are clickable to obtain more information. as most users are not expected to know sparql, the query language for the semantic web, the system offers a user-friendly method for semantic search: a query string entered between square brackets, for example “[roman emperor]”, is expanded by a “best guess” sparql query in wikidata, in this case resulting in entities having the property “position held=roman emperor.”. these in turn are used to do a search for articles containing one or more mentions of a roman emperor, even if the text “roman emperor” is not present in the article. in another example, when a user searches for the term “[beatles]” the “best guess” search yields articles mentioning entities with the property “member of=the beatles”. for ambiguous items, as in the case of “guernica,”, which can be the place in spain or picasso’s painting, the one with the highest number of occurrences in the newspapers is selected by default, but the user may select another one. for information technology and libraries | june 2019 75 the default or selected item, the user can select a specific property from a list of wikidata properties available for that specific item. the possibilities of this semantic search functionality may inspire others to use the wikidata identifier for globally known entities in other systems as well. figure 3. screenshot of the kb research portal with a newspaper article as result of searching “[architect=willem dudok]”. the results are articles about buildings of which willem dudok is the architect. the name of the building meeting the query [architect=willem dudok] is highlighted. usage scenarios two usage scenarios can be considered in more detail: (1) manually following links between wikidata descriptions and other resource descriptions, and (2) a federated sparql query can be performed by the system to automatically bring up linked entities. in the first scenario, in which resource identifiers link to wikidata, the user can follow the link to all resource descriptions having a backlink in wikidata. but why would a user follow such a link? reasons may include wanting more or context-specific information about the entity, or a desire to search in another system for objects mentioning a specific entity. in the latter case, the information behind the backlink should provide a url to search for the entity, or the backlink should be the search url itself. wikidata provides the possibility to specify various uri templates. these can be used to specify a link for searching objects mentioning the entity, rather than just showing a thesaurus entry. when the backlink does not provide extra information or a way to search the entity, the backlink is almost useless. thus, when systems provide resource links to wikidata they give users access to a wealth of information about an entity in the web of data and, potentially, to objects mentioning a specific entity. some systems only provide backlinks from wikidata | van veen 76 https://doi.org/10.6017/ital.v38i2.10886 wikidata to their resource descriptions but not the other way around. users from such systems cannot easily benefit from these links. the second scenario of a federated sparql query applies when searching objects in one system based on properties coming from other systems. formulating such a sparql query is not easy because doing so requires a lot of knowledge about the linked data cloud. the alternative is to put the complete linked data cloud in a unified (triple store) database. the technology of linked data fragments might solve the performance and scaling issues but not the complexity. 8 using a central knowledge base like wikidata could reduce complexity for the most common situation of searching objects in other systems using properties from wikidata. this use case requires these systems to take the users query and automatically formulate a sparql search. there are many systems that are linked to wikidata that do not support sparql at all or only support it in a way that is not intended for the average user. those systems can still let users benefit from wikidata by offering a simple add-on to search in wikidata for entities that meet some criteria and use the identifiers for a conventional search in the local system as shown for the case of the historical newspapers. these two use cases illustrate how the use of a wikidata identifier can lower the barrier to access information about an entity and to finding objects related to an entity by minimizing the number of hubs, minimizing the required knowledge and minimizing the required technology. this is achieved by linking resources to wikidata and, even more so, by making objects searchable by means of the wikidata identifier. advantages of using the wikidata identifier as universal identifier summarizing the above, a number of significant advantages of using the wikidata identifier as universal identifier can be seen. these include: • using the wikidata identifier as resource identifier makes wikidata the first hub. applications therefore have in the first instance to deal with only one description model. from there, it is easy to navigate further: most information is only “one hub away,” so less prior knowledge is required to link from one source to another. • wikidata identifiers can be used for federated search based on properties in wikidata, so there is less need to know how to access properties in other resource descriptions. • wikidata identifiers facilitate generating “just in case” links to systems having the wikidata identifier indexed. • complicated sparql queries using wikidata as primary source for properties can be shared and reused more easily compared to a situation with many diverse sources for properties. • wikidata offers many tools and apis for accessing and processing data. • some libraries and similar institutions may even decide to use wikidata directly for authority control when it reaches a critical mass, relieving them from maintaining a local thesaurus. implementation institutions can gradually adopt the use of wikidata identifiers without needing to make radical changes in their local infrastructure. a simple first step is automatically generating links to information technology and libraries | june 2019 77 wikidata in the presentation of an object or to the object description to provide contextual information and navigation options. as a next step, the wikidata q-number of an entity could be indexed along with the descriptions containing it, so these objects become findable via a wikidata identifier search, e.g. of the form: https://whatever.local/wdsearch?id=q937 the wikidata identifier could then be used in conventional as well as federated searches for a resource, regardless of the exact spelling of a resource name. a search may be refined using wikidata properties without further requirements with respect to local infrastructures. institutions having a sparql endpoint can allow for a federated sparql query for combining local data with data from wikidata. as sparql is not easy for the end user this requires a user interface that can formulate a sparql query to protect the user from knowing sparql. those institutions willing to start using the wikidata identifier as resource identifier can unify references in their bibliographic records. currently, for example, a reference to albert einstein, in a simplified, rdf-like (https://www.w3.org/rdf/) xml fragment in a bibliographic record, could look quite different for different institutions, e.g.: <creator rdf:resource=”http://data.kb.nl/thesaurus/068350767”>albert einstein</creator> <creator rdf:resource=” http://bnb.data.bl.uk/id/concept/person/lcsh/einsteinalbert18791955”>albert einstein</creator> <creator rdf:resource=” http://data.bnf.fr/11901607/albert_einstein/”>albert einstein</creator> <creator rdf:resource=” http://id.loc.gov/authorities/names/n79022889”>albert einstein</creator> if the wikidata identifier is used as resource identifier, this could for all institutions become the same: <creator rdf:resource=”https://www.wikidata.org/wiki/q937”>albert einstein</creator> in this case it becomes easy to navigate the web, to create common bookmarklets, and provide additional functionality using the wikidata identifier. cataloguing process and criteria for new wikidata entries for institutions that decide to link their entities directly to wikidata, their catalog software would have to be configured to support wikidata lookups. catalogers would not have to know about linked data or rdf to create links to wikidata; they would simply have to query wikidata and select the appropriate entry to link. the cataloging software would then add the selected identifier to the record being edited. if a query in wikidata does not yield any results the item would first then have to be created by the cataloger. creating a new item using the wikidata user interface (figure 4) is straightforward: create an account, add a new item, and add statements (fields) and values. wikidata | van veen 78 https://doi.org/10.6017/ital.v38i2.10886 figure 4. data entry screen for entering a new item in wikidata. catalogers must be aware of some rules when creating items. wikidata editors may delete items that fall under one of wikidata’s exclusion criteria, such as vandalism, empty descriptions, broken links, etc. in addition, the item must refer to an instance of a clearly identifiable conceptual or material “notable” entity. notable means that the item must be mentioned by at least one reliable, third-party published source. here, common sense is required: being mentioned in a telephone book or a newspaper is in itself not considered as notability. entities that are not notable enough to be entered into wikidata would then remain identified by a link to a local or other thesaurus. possible objections to wikidata as authority control mechanism although it is, at least at the present moment, not the intention of this article to propose the use of wikidata as the primary local authority control mechanism, some institutions may nonetheless consider the opportunity to do so. there are numerous objections to this idea to note, including: 1) institutions may consider themselves authoritative sources of information, and may therefore want to keep control over “their” thesaurus. the idea that the greater community can make changes to “their” thesaurus may not be tenable to them. quality control and error detection certainly are important issues, but experts from outside the library can sometimes provide more and better information about a resource than cataloguing professionals. for misuse and erroneous input, the community can be relied on and trusted to correct and add to wikidata entries. information that is critical for local usage, such as access control, may still be managed locally. despite possible objections to using wikidata for universal authority control, national libraries and other institutions can information technology and libraries | june 2019 79 work together with wikidata to share responsibility of maintaining the resource, to optimize and harmonize the shared use of wikidata, and maintain validity and authority. this might imply a more rigorous quality control. 2) existing systems like viaf and isni already, at present, still contain more persons than wikidata, so why use wikidata? viaf and isni are domain specific and are more restrictive with respect to updates of their content and the availability of tools and apis. in wikidata both viaf and isni are just one hub away and for internal use the viaf and isni identifiers remain available. the question here is whether there will be a moment that wikidata reaches a critical mass and supersedes viaf and isni. 3) there may be disagreement about a certain entity, especially when it concerns political events or persons whose role is perceived differently by different political parties. wikidata contains neutral properties. the properties that may contain subjective qualifications or might suffer bias are mostly behind the backlinks, like the abstract in wikipedia. a fundamental difference between wikipedia and wikidata is that wikipedia doesn’t have to be consistent across languages. wikidata is much more structured and therefore more useful for semantic applications. it doesn’t allow for the different nuances in descriptions like wikipedia articles do and therefore wikidata doesn’t reflect different opinions in descriptions and is less subject to bias.9 furthermore, the cataloguing practices in libraries are subject to bias and subjectivity too. perception and political view may, for example, be reflected in some subject headings and may also change over time.10 it is debatable whether a cataloger is more neutral and less biased than a larger user community. although the use and acceptance of wikipedia as a true source of information may be arguable, in the light of the current “fake news” discussion it is extremely important to guard the correctness of information in wikipedia. in this context it is interesting to note that “according to a study in nature, the correctness of wikipedia articles is comparable to the encyclopaedia britannica, and a study by ibm researchers found that vandalism is repaired extremely quickly.”11 4) some objections have to do with the discussion of “centralization versus decentralization.” some institutions may not want a central system perceptively having control over their local data. the idea of using wikidata as a common authority control mechanism is not that different from the use of any other thesaurus or identifier framework like isbn, issn, etc., except for its use of a central resource description. 5) what if wikidata disappears? there are solutions in terms of mirrors and a local copy of wikidata. moreover, national libraries and other, similar institutions that are already responsible for long-term preservation of digital content can take responsibility for keeping wikidata alive to maximize its viability wikidata | van veen 80 https://doi.org/10.6017/ital.v38i2.10886 conclusion reconciliation of linked data identifiers in general, and using the wikidata identifier as universal identifier in particular, has been shown to have many advantages. libraries and similar institutions can gradually start using the wikidata identifier without needing to make radical changes in their local database infrastructure. when wikidata reaches a critical mass, libraries and similar institutions may want to switch to using wikidata identifiers as the default resource identifiers or authority records. however, given the enormous growth of the number of collections that link entities to wikidata that is already taking place, we might end up in a situation where the perception is that “if an item is not in wikidata, it doesn’t exist” stimulating putting more items in wikidata and making local descriptions less relevant. from a strategic point of view for adopting wikidata decision makers may pose the question: “why do we have a local thesaurus when we already have wikidata?” the next question, then, will probably not be “should we go this way?” but rather “when should we go this way and start using the wikidata identifier as the identifier?” references 1 robert sanderson, “the linked data snowball and why we need reconciliation,” slideshare, apr. 4, 2016,

(mcyzyk@jhu.edu), a member of lita and the ital editorial board, is the scholarly communication architect in the sheridan libraries, the johns hopkins university, baltimore, maryland. in the quarter century since graduating from library school, i have now and then run into someone who had what i consider to be a highly inaccurate and unintuitive view of librarians and information technology. seemingly, in their view, librarians are at worst luddites and at best technological neophytes. not so! in my view, librarians have always been at worst technological power users and at best true it innovators. one has only to scan the first issues of ital, or the journal of library automation as it was then called, to put such debate to rest. march 1968 saw the first issue of the first volume of the journal of library automation published. the first article of that inaugural issue sets the scene: “computer based acquisitions system at texas a&i university” by ned c. morris. here we find librarians not only employing computing technology to streamline library operations (using an ibm 1620 with 40k ram), but as the article points out, this new system for computerizing acquisitions was an adjunct to the systems they already had in place at texas a&i for circulation and serials management. this first article in the first issue of the first volume indicates that we’ve dipped a toe into a stream that was already swiftly flowing. the other bookend of that first issue, “the development and administration of automated systems in academic libraries” by harvard’s richard de gennaro, goes meta and takes a comprehensive look at how automated library systems were already being created and the various system development and implementation rubrics under which such development occurred. much in this article should resonate with current readers of ital. i knew immediately that this article was going to be a good read when i encountered, in the very first paragraph: development, administration, and operations are all bound up together and are in most cases carried on by the same staff. this situation will change in time, but it seems safe to assume that automated library systems will continue to be characterized by instability and change for the next several years. i’d say that was a safe assumption. the second and final volume of the 1960’s contains gems as well. the entirety of volume 2 issue 2 that year was devoted to “usa standard for a format for bibliographic information interchange on magnetic tape” a.k.a. marc ii. is it possible for something to be dry, yet fascinating? some titles of this second volume point to the wide range of technological projects underway in the library world in 1969: mailto:mcyzyk@jhu.edu the 1960s in review | cyzyk 7

volume of ital proceeds, we’ll be surveying the morphing information technology and libraries landscape through ital articles of the seventies, eighties, and nineties. i think you will see what i mean

library management articles integrated technologies of blockchain and biometrics based on wireless sensor network for library management meng-hsuan fu information technology and libraries | september 2020 https://doi.org/10.6017/ital.v39i3.11883 meng-hsuan fu (msfu@mail.shu.edu.tw) is assistant professor, shih hsin university (taiwan). © 2020. abstract the internet of things (iot) is built on a strong internet infrastructure and many wireless sensor devices. presently, radio frequency identification embedded (rfid-embedded) smart cards are ubiquitous, used for many things including student id cards, transportation cards, bank cards, prepaid cards, and citizenship cards. one example of places that require smart cards is libraries. each library, such as a university library, city library, local library, or community library, has its own card and the user must bring the appropriate card to enter a library and borrow material. however, it is inconvenient to bring various cards to access different libraries. wireless infrastructure has been well developed and iot devices are connected through this infrastructure. moreover, the development of biometric identification technologies has continued to advance. blockchain methodologies have been successfully adopted in various fields. this paper proposes the blockmetrics library based on integrated technologies using blockchain and finger-vein biometrics, which are adopted into a library collection management and access control system. the library collection is managed by image recognition, rfid, and wireless sensor technologies. in addition, a biometric system is connected to a library collection control system, enabling the borrowing procedure to consist of only two steps. first, the user adopts a biometric recognition device for user authentication and then performs a collection scan with the rfid devices. all the records are recorded in a personal borrowing blockchain, which is a peer-to-peer transfer system and permanent data storage. in addition, the user can check the status of his collection across various libraries in his personal borrowing blockchain. the blockmetrics library is based on an integration of technologies that include blockchain, biometrics, and wireless sensor technologies to improve the smart library. introduction the internet of things (iot) connects individual objects together through their uniqu e address or tag, which are based on the sensor devices and wireless network infrastructure. presently, “smart living” (a term that includes concepts such as the smart home, smart city, smart university, smart government, and smart transportation) is based on the iot, which plays a key role to achieve a convenient and secure living environment. gartner, a data analytics company that presents the top ten strategic technology trends for the next year at the end of each year, listed blockchain as one of the top ten in 2017, 2018, 2019, and 2020.1 the fact that blockchain has been proposed as one of the top strategic technology trends for four consecutive years represents its sustained interest among technology experts and developers. in a blockchain, a block is the basic storage unit where data is saved and protected with cryptography and complex algorithms. the technology of peer-to-peer transfer is adopted mailto:msfu@mail.shu.edu.tw information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 2 when data or information is exchanged without the need for a third party. in other words, data is transferred directly from node to node or user to user thanks to the decentralized nature of the blockchain. in addition, blockchain is authorized and maintained by all nodes in the same blockchain network. each node has equal right (also known as equal weight) to access the blockchain and authorize new transactions. thus, all transactions are published and broadcast to all nodes and content cannot be altered by single or minority users or nodes. additionally, transaction content is secured by cryptography and complex secure algorithms. therefore, transactions occur and are preserved under a fully secure and private network. in practice, the blockchain has been applied to various fields including finance, medicine, academia, and logistics. the blockchain has also been adopted for personal transaction records for its privacy and security properties and because it offers immutable and permanent data storage. in this research, blockchain technologies are adopted to store the records of collections borrowed from various libraries in a personal borrowing blockchain. table 1. definition of key terms of blockchain key term definition blockchain a blockchain comprises many blocks. it has the characteristics of security, decentralized, immutability, distributed ledgers, transparent log, and irreversible data storage. block a block is the basic unit in blockchain. each block consists of a block header with nonce, previous block hash, timestamp, merkle root, and many transactions in a block body. nonce the counter of the algorithm, hash value will be changed once the nonce modified. merkle root a secure hash algorithm (sha) is used in merkle root to transform data into a meaningless hash value. transaction each transaction is composed of address, hash, index, and timestamp. all transactions will be stored in blocks permanently. hash secure hash algorithm (sha) transforms input data into meaningless output data, called a hash, which consists of english letters and digital numbers, in order to protect data content during transmission. biometrics using human physical characteristics including finger vein, iris, voice, and facial features for recognition. sensor network a sensor is a small and portable node with a data record function and power source. a sensor network is composed of many sensors based on a communication infrastructure. iot internet of things (iot) is a system to connect sensors and devices together under an internet environment. presently, many iot applications were adopted such as smart home, health care, and smart transportation. information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 3 although the iot and wireless networks have been well developed, people still own many different rfid-embedded cards, such as public transportation cards, credit cards, student cards, medical cards, identification cards, membership cards, or library cards. an rfid-embedded card is issued for each place or purpose, requiring the user to bring the appropriate cards to access the corresponding functions. in this study, the library is used as the objective to which blockchain technologies are applied because currently each library has its own library card for entering the library and borrowing material. this implies that users may have to carry several library cards to access each of a university library, community library, and district library on the same day. here, biometrics can be adopted to solve the problem of having to carry many access control cards and managing various borrowing policies. in this study, the blockmetrics library is designed based on the technologies of blockchain and biometrics within the environment of a wireless sensor network with iot devices. here, borrowing records are transferred and stored through blockchain technologies, automatic library access control is managed by biometric identification and the borrowing and returning of library materials are achieved under a wireless sensor network with iot devices to create a convenient, efficient, and secure library environment. the key terms of blockchain and its related terms, biometrics, sensor network and iot applied in this research are defined in table 1. related works blockchain technology nakamoto has presented bitcoin as a peer-to-peer electronic system that uses blockchain technologies, which include smart contracts, cryptography, decentralization, and consensus in proof of work. because this electronic system is based on cryptography, a trusted third party is not required in the payment mechanism. additionally, peer-to-peer technology and a timestamp server are adopted and a block is given a hash in serial order. this procedure solves the problem of double-spending during payment.2 in addition, proof of work is used in a decentralized system for authentication by most nodes in the blockchain network. each node has equal rights to compete to receive a block and each node can vote to authenticate a new block. 3 košt’ál et al. define proof-of-work (pow) as an asymmetric method with complex calculations where its difficulty is adjusted by the problem-solving duration.4 however, pow has drawbacks, such as high power consumption and the fact that some users can control the blockchain if their shares of users in the same blockchain network reach 51 percent.5 despite the possible presence of malicious parties, the information in a blockchain is difficult to modify because of the distributed ledger methodology in which each node has the same copy of ledger, making it difficult for a single or minority node to change or destroy the stored data. 6 a block is a basic unit in a blockchain. in other words, a blockchain is composed of blocks that are connected. one of the blockchain technologies is the distributed ledger, in which a ledger can be distributed to each node all over the world.7 each block is composed of a block body and header, and a block size is 4 bytes. the block header is a combination of the version, previous block hash, merkle root, timestamp, difficulty target, and nonce. a blockchain is 80 bytes in total and transactions are between 1 to 9 bytes (see table 2). information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 4 table 2. block element. block size 4 bytes size block header (80 bytes) 4 bytes version 32 bytes previous block hash 32 bytes merkle root 4 bytes timestamp 4 bytes difficulty target 4 bytes nonce block body 1-9 bytes transactions blockchain technologies have been applied to various fields including finance, art, hygiene, healthcare, and academic certificates. for example, in healthcare, user medical records are stored in a blockchain so users can check their health conditions and share them with their family members in advance. in business, blockchain is adopted into the supply chain management for monitoring activities during goods production. in the academic field, the certificates are permanently saved in a blockchain where users can retrieve them from their mobile devices and show them upon request.8 because blockchain is protected by cryptography and offers privacy, reliability, and decentralization, an increasing number of applications are beginning to adopt it. as an application for a library system, a blockchain, in combination with biometrics within a wireless infrastructure, can be adopted for personal borrowing records. library borrowing management each library has its own regulations. for example, the national central library (ncl) in taiwan has created reader service directions in which the general principles and rules for library card application, reader access to library materials, reference services, request for library materials, violations, and supplementary provisions are clearly stated. according to the ncl reader service directions, citizens are required to present their national id card and foreigners are asked to present their passport to apply for a library card. users are allowed to access the library when they have a valid library card. those who have library cards but have forgotten to bring them can apply for a temporary library card to enter the library, but this is limited to three times.9 this rule is only specific to the ncl. other libraries in the same country have their own regulations. another example is the taipei public library. citizens can apply for a library card using their citizen’s id card, passport, educational certificate, or residence permit. a taipei citizen can apply for a family library card using their family certificate. users can borrow material and return the material to all the libraries in taipei city. however, these policies are only applicable to users who hold library cards issued by libraries in taipei city.10 as for university libraries, each library also has its own regulations. for instance, shih hsin university (shu) issues its own library card to access its library. alumni are requested to present their id cards and photo to apply for a library card in person. the number of items and their loan periods are clearly stated in the rules set by the shu library.11 again, the regulations are individually set by each university library. information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 5 biometrics rfid-embedded smart cards such as student cards, transportation cards, and bank cards are widely used, however, they can be stolen, lost, or forgotten at home. biometrics is becoming more widely used in access-control systems for homes, offices, buildings, government facilities, and libraries. for these systems, the fingerprint is one of the most commonly used biometrics. users place their finger on a read device, usually a touch panel. this method ensures a unique identity, is easy to use and widely accepted, boasts a high scan speed, and is difficult to falsify. however, its effectiveness is influenced by the age of the user and the presence of moisture, wounds, dust, or particles on the finger, in addition to the concern for hygiene because of the use of touch devices. face recognition has been used in various applications such as unlocking smart devices, performing security checks and community surveillance, and maintaining home security. this method of biometric identification is convenient, widely accepted, difficult to falsify, and can be applied without the awareness of the person. however, limitations to face recognition include errors that can occur due to lighting, facial expression, and cosmetics. also, privacy is an issue in face recognition because it may take place at a distance without the user’s consent. another form of biometric identification uses the iris as an inner biometric indicator because th e iris is unique for each person. nevertheless, this method is also prone to errors that can be caused by bad lighting and the possible presence of diseases such as diabetes or glaucoma. devices used for iris recognition are expensive, and thus rarely adopted in biometrics.12 speech recognition is used for equipment control such as a smart device switch, however, it can be affected by noise, physical conditions of the user, or weather. vein recognition using finger or palm veins is becoming more prevalent as a form of biometric identification for banks or access control but can be limited by the possible presence of bruises or a lower temperature. however, vein recognition ensures a unique identity, is easy to use, convenient, accurate, and widely accepted, thus, many businesses are adopting vein recognition for various usages. to summarize, biometric identification is convenient, reduces the error rate in recognition, and is difficult to falsify. therefore, biometric identification is suitable for access control. blockmetrics library the blockmetrics library is based on the integration of blockchain and biometric technologies in a wireless sensor network with iot devices. figure 1 shows the blockmetrics library architecture with its bottom-up structure consisting of five layers: hardware, software, internet, transfer and security, and application. all components are sequentially described in detail from the bottom to the top layers. in the hardware layer, sensor nodes are physically located on library collection shelves, entrance gates, and relevant equipment to be further connected with the upper layers. rfid tags are attached to each item in the library, including books, audio resources, and videos. tag information is read and transferred by rfid readers. the biometric devices used in this study include fingerprint readers, palm and finger-vein identifiers, and face or iris recognition devices for biometric authentication when users enter libraries or borrow collections. all images including action images, collection images, and surveillance images are recorded with cameras. the ground surveillance, library collection recognition, image processing, and user identification are manipulated by graphics processing units. touch panels are used for typing or searching for information and there is a particular process for user registration. for general input and output of information, i/o devices include speakers, microphones, keyboards, and monitors. the entrance gate is connected to biometric devices and recognition systems for automatic access control. microprocessors and servers, which make up the core of the hardware, handle all the functions that run in the operating system. data and programs are run and securely saved on a large information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 6 memory drive. data transmission occurs through the wireless data collector, and data collection and transfer in the library are based on a wireless environment. in the blockmetrics library, a library collection database is used to store and maintain all the library material information in a local library for backup usage, and a blockchain is used to record personal borrowing and returning history. figure 1. blockmetrics library architecture in the software layer, an open-source word processor (such as writer, impress, or calc provided by libreoffice) is used to record library collections and handle library affairs. biometric recognition identifies a user’s biological features collected from biometric devices such as a fingervein recognition device, which is adopted in this research. all images and videos include ground information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 7 and entrance surveillance and library material borrowing and returning are recorded by cameras. all images and videos are operated by and processed with video-processing software. the data of the images, videos, personal information, and library collections is managed and saved through an image and file management system as well as a database management system. the software programs associated with creating, modifying, and maintaining library processes are written with open-source programming codes, in particular, python and r, which were scored as two of the top ten programming languages by ieee spectrum in 2019.13 there are various functions saved as packages that are free to download and can be modified and reproduced into a customized program for specific purposes. the hardware houses the cpu, which runs the general library operations, and software programs are maintained by the operating system and management information system. library stock management, collection search, personal registration, and other library-related functions can be designed and developed through app inventor. each borrow and return record is connected with the personal identification recognized from the finger-vein reader and recognition system and is saved as a transaction. the transactions that take place in a specific period are saved in a block that can be connected to another block to form a personal borrowing blockchain. the internet technology layer is built upon the hardware and software structure. the main purpose of internet technologies is to connect the equipment and devices with the internet, in which the internet plays the role of an intermediary for all devices communicating and cooperating together in the library. in the internet technology layer, bluetooth connects devices such as earphones, speakers, and audio guidance within short distances. files are exchanged between smart devices, including smartphones, tablets, or ipads, through near-field communication, which is a contact-less sensor device. rfid is adopted for collection borrowing and returning services in the library. because fiber-optic cables have been ubiquitously planted within infrastructure with the development of smart cities, most libraries have also been built with them. users or vehicles are more easily and more accurately located by the global positioning system (gps), which also assists with image recognition when a material is taken from the shelves. sensors transfer the sensing data to the relative devices for recording or processing under the infrastructure of the wireless sensor network. the library is currently built with a wi-fi environment, but li-fi is one of the future trends that involve creating a wireless environment just with light. mobile devices operate under wireless communications and most countries provide 4g and 4g+ with some supporting even 5g. the internet technology layer is the tools provider for intercommunication among devices. data security and transmission reliability are extremely important issues when various equipment is linked together and connected to the internet. the user interface is the bridge between the user and the devices. in other words, the user gives commands to the devices or software through a user interface or app. biometric recognition devices, rfid readers, and entrance control equipment are connected via the internet in this study. the devices send the information to the corresponding devices for specific purposes in a specified order. collected data such as private user identification are secured by cryptography utilized in blockchain technology. the finger-vein identification used as personal identification is combined with the borrow and return records, stored as transactions, and secured under a secure hash algorithm before being saved into a blockchain. all data and personal identification are transferred under the corresponding secure methodologies. information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 8 in the blockmetrics library, self-check-in and self-checkout rely mostly on rfid technology and finger-vein biometrics. the borrow and return records are stored in a personal borrowing blockchain, where records are saved in the blockchains of user and library, biometrics system, and library servers. entrance control is automatically managed by finger-vein recognition. library stock management is particularly based on image assistance and rfid technology. new user registration is performed only through a few identification questions and finger-vein characteristics extraction. the blockmetrics library is without a circulation desk environment and has an automated borrow and return mechanism through a single sign at the entrance and exit. the five layers in the blockmetrics library architecture communicate with each other such that operations are inseparably related. the blockmetrics library scenario is described in the next section. scenario in this section, the scenarios for registration, entry, and material borrowing and returning in the blockmetrics library will be described in detail. in figures 2 and 3, the user side indicates the actual user actions and is represented as solid lines and the background shows mostly background operations and is indicated as dotted lines. in figure 2, when a new user comes into the blockmetrics library, the registration procedure starts with a biometric pattern extraction and recognition of the user. finger-vein authentication is selected as the personal biometrics for entrance and material borrowing. on the user side, registration is completed with only two steps. the first is finger-vein extraction and the second is to simply provide personal information. the biometric recognition data is processed and stored in the appropriate database, which is linked to the personal identification management system. personal information is secured through the cryptography used in blockchain technology, thus, all information is securely stored. the registration procedure is performed only once at the first entry, and afterward all registered users can enter the blockmetrics library using finger-vein authentication. biometric recognition proceeds with a biometrics database that verifies user identity followed by verification results sent to the entrance control management for entrance guarding. the entrance is automatically controlled because the results from the biometric recognition step are sent as the rules for entrance control. users will be permitted to enter the library when they pass the biometrics recognition step. users do not have to bring their library cards to enter or borrow material, increasing convenience and decreasing identity infringement when library cards get lost. figure 3 shows the scenario of library material borrowing and returning. on the user side, library material borrowing consists of four simple steps performed by the user: 1) retrieving items, 2) authenticating with the finger-vein recognition device, 3) placing items on the rfid reader, and 4) exiting the library. when the user removes a book from the shelf, an infrared detector is triggered, recognizing that a book was removed from the shelf. then, image recognition identifies the specific book and the book’s status is marked as charged to the user in the stock database. if the user wants to leave the library without borrowing anything, the user just scans their finger with the finger-vein device to open the entrance gate. if the user wants to borrow library materials such as books or videos, the borrowing procedure is quickly completed after finger-vein scanning and placing all material including books and videos under the rfid read area. in the background, the user’s recognition results from the finger-vein scan are saved in the biometrics database, which is connected to the blockchain. when the library materials are placed together in the rfid read area, all the tags are read at once while the materials’ statuses in the information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 9 database are updated. user information and material borrowing information are linked and saved as transactions that are stored in the personal borrowing blockchain. figure 2. blockmetrics library scenario—registration and entry information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 10 figure 3. blockmetrics library scenario – borrowing and returning to return library material, the user only needs to put the library materials in the specific area with the rfid reader and the return procedure is completed. the rfid tags of returned materials are read and recorded and their status in the stock database is updated. personal borrow and return records are saved as transactions and stored in the personal borrowing blockchain as well. limitations partial biometric technologies such as facial recognition or fingerprint recognition systems have been adopted by some libraries. these tools have increased the efficiency of accessing and borrowing procedures. however, all the records include some personal information (e.g., fingerprint, historical borrowing records, log of library access, etc.) that is still stored in the individual libraries’ database. the blockchain model may not suitable for all current libraries system due to the unknown database design of each library. at present, library classification systems are by each library individually. therefore, integrating library information among national or international libraries will be a huge task. thus, how to establish the general regulations for all libraries to develop and manage the library information will need additional information technology and libraries september 2020 integrated technologies of blockchain and biometrics | meng-hsuan fu 11 research. after that, the information management system should be designed and built by collecting diverse comments from all library managers. the works should be completed by interdisciplinary experts including library management, information engineering, biometrics system design, and data management. the cost may include manager committees, collection coding design, system development, hardware layout, and related training plans. also, th ere may exist unpredictable privacy issues which could be known until practical system operation. lastly, some users need an adaptation period while new technologies are implemented, the duration of which can depend on how smooth the interface design is, if the system manipulation is easy and clear to use, and what benefits the technologies bring to users’ life. the limitations are concluded as: 1) integrating library information such as stock data and serial numbers, 2) establishing general regulations, 3) creating a consistent library management system, 4) the cost for this system, 5) potential for privacy breaches, and 6) library patron resistance or reluctance to use the technology. conclusion in this research, the blockmetrics library is designed under a wireless sensor network infrastructure combined with blockchain, biometric, iot, and rfid technologies. the library access control system is based on finger-vein biometric recognition, in which users can register with their finger-vein information through biometric devices and input personal information via various i/o devices. thus, automatic and secure library access control is achieved through biometric recognition. additionally, image recognition, gps, and rfid are adopted in the library collection management, providing a simplified way to borrow and return library material. blockchain technologies are utilized to record personal borrowing history of collections from various libraries into a personal borrowing blockchain where records are permanently stored. users can clearly understand their borrowing status through their own blockchain and manage their borrowing information through an application. to summarize, users can enter the library with finger-vein recognition instead of a specific library card. then, if they would like to check out library material, the user can retrieve the items, pass them through the rfid reader, scan their finger vein, and go. the blockmetrics library is designed for convenience and security, which are achieved by combining a wireless sensor network with the integration of blockchain and biometric technologies. this method eliminates the inconvenience of having to bring many library cards, increases the efficiency of collection borrowing procedures, and simplifies the management of collection borrowing from different libraries. adoption of these biometric technologies is still in its early stages. some libraries have begun using different tools, but few libraries have adopted all of them. it simplifies both accessing and borrowing procedures, and all the records are still stored in a particular library’s database for private access only. the development of the blockmetrics library will help to integrate biometric technologies and blockchain under the infrastructure of wireless sensor network to maintain library-accessing recognition, library collections, library users, borrowing records crossing libraries to raise the user convenience and satisfactions, library management efficiency, and library security. in the near future, the library transaction formula in a blockchain will be developed for collection borrowing storage. the library collection serial numbers will be considered in information management system as well. information technology and libraries september

https://spectrum.ieee.org/computing/software/the-top-programming-languages-2019 abstract introduction related works blockchain technology library borrowing management biometrics blockmetrics library scenario limitations conclusion endnotes article title | author 33online workplace training in libraries | haley 33 this study was designed to explore and describe the relationships between preference for online training and traditional face-to-face training. included were variables of race, gender, age, education, experience of library employees, training providers, training locations, and institutional professional development policies, etc. in the library context. the author used a bivariate test, kruskalwallis test and mann-whitney u test to examine the relationship between preference for online training and related variables. i n the era of information explosion, the nature of library and information services makes library staff update their work knowledge and skills regularly. workplace training has played an important role in the acquisition of knowledge and skills required to keep up with this information explosion. as richard a. swanson states, human resource development (hrd) is personnel training and development and organization development to improve processes and enhance the learning and performance of individuals, organizations, communities, and society (swanson 2001). training is the largest component of hrd. it helps library employees acquire more skills through continuous learning. online workplace training is a relatively new medium of delivery. this new form of training has been explored in the literature of human resources development in corporation settings (macpherson, elliot, harris, and homan 2004), but it has not been adequately explored in university and library settings. universities are unique settings in which to study hrd, and libraries are unique settings in which to examine hrd theory and practice. in human resource development literature there are studies on participation (wang and wang 2004) from the perspective of individual motivation, attitudes, etc.; however, more research needs to be conducted to explore library employees’ demographics related to online training in the unique library contexts, such as various staff training and development, as well as training policies. hrd literature includes studies of online learning in formal educational settings (hiltz and goldman 2004; shank and sitze 2001; waterhouse 2005), and there are studies on relationships between national culture and the utility of online training (downey, wentling, wentling, and wadsworth 2005). but there has been very little research conducted in terms of online workplace training for library staff. it is not clear what relationships exist among preferences for online training and demographic variables such as ethnicity, gender, age, educational level, and years of library experience. due to lack of research in these areas, workplace training in libraries will be less effective if certain ethnic groups, or certain age groups, prefer traditional face-to-face training as libraries move toward online training. the author believes that research should govern library practice. therefore, it is necessary to research this topic and disseminate the findings. because of the growth in online training, there is a need to gain a better understanding of these relationships. ■ purpose of the study the study aims to reveal the relationships between preferences for online or traditional face-to-face training and variables such as ethnicity, gender, age, educational level, and years of experience. it also studies the relationships among preference for online training and other variables of training locations, training providers, training budgets, and professional development policies. the constructs are: the preference for online training was related to demographics, library’s training budget, professional development policies, training providers, and the training locations. these factors were included in the research questionnaire. we begin with the research questions, review the current literature, and then discuss the method, results, and need for further research. correlational research questions 1. what is the relationship between ethnicity and online workplace training preferences? 2. what is the relationship of employees’ educational levels, age, and years of library experience to online workplace training preferences? 3. how does preference for online workplace training in libraries relate to employee gender? 4. how does preference for online workplace training in libraries relate to training locations, training providers, training budgets, and professional development policies? 5. do library staff prefer traditional face-to-face training over online training? ■ review of the literature as stated above, training is the largest component of hrd. the discipline of hrd relies on three core theories: psychological theory, economic theory, and system theory. swanson (2001) stated: online workplace training in libraries connie k. haley connie k. haley (chaley@csu.edu) is systems librarian, chicago state university library, illinois 34 information technology and libraries | march 200834 information technology and libraries | march 2008 economic theory is recognized as a primary driver and survival metric of organizations; system theory recognizes purpose, pieces, and relationships that can maximize or strangle systems and subsystems; and psychological theory acknowledges human beings as brokers of productivity and renewal along with the cultural and behavioral nuances. each of these three theories is unique, complementary, and robust. together they make up the core theory underlying the discipline of hrd (p. 92–93). three specific economic theory perspectives are believed to be most appropriate to the discipline of hrd: (1) scarce resource theory, (2) sustainable resource theory, and (3) human capital theory (swanson 2001). training is an investment to human capital with valuable returns, but no costs. wenger and snyder’s study (as cited in mahmood, ahmad, samah, and idris 2004) states that today’s economy runs on knowledge and skills. thurow’s study (as cited in swanson 2001) states that new industries of the future depend on brain power. man-made competitive advantages replace the comparative advantage of natural-resources endowments or capital endowments. in a rapidly changing society, maintaining organizational and individual competence has become a greater challenge than ever before (hake 1999). competences include knowledge, skills, and attitudes. much of the literature focuses on job-related functional competences (deist and winterton 2005). library workplace training is one of the primary methods of investing in human capital and increasing competence for library employees. training is the process through which skills are developed, information is provided, and attributes are nurtured (davis and davis 1998). to increase training participation and efficacy, libraries need to determine employees’ preferences for online training or traditional face-to-face training; a resulting high training participation rate would increase the competence of all employees. library trainers and administrators can encourage nonparticipants to attend training by offering different training sessions (online or face-to-face), and/or by changing training policies and budget allocations. unlike personality and intelligence, skill competence may be learned; hence it may be improved through training and development (mcclelland 1998). nadler and tushman (1999) emphasized core competence as a key organizational resource that could be exploited to gain competitive advantage. core competence was defined as collective learning in the organization, especially how to coordinate diverse production skills and integrate multiple streams of technologies (prahalad and hamel 1990). mezirow (2000) asserted that there are asymmetrical power relationships that influence the learning process (as cited in baumgartner 2000). learning more about the relationships may benefit training and learning. in other words, training may be more effective if it is provided in the form preferred by the majority of staff. as stated above, there is very little research about online workplace training for library staff. past studies have focused on how to conduct online training for working catalogers (ferris 2002) or on online teaching for students (crichton and labonte 2003; hitch and hirsch 2001). from the design and implementation perspectives, kovacs (2000) discussed web-based training in libraries, and unruh (2000) emphasized problems in delivery of web-based training. markless (2002) addressed learning theory and other relevant theories that could be used to teach in libraries. yet there is a lack of research on the demographics of library staff participation in workplace training and a lack of research on the training preferences of library staff. ■ methodology the study took place in an online environment. the research activities covered a twenty-day period from april 10 to april 30, 2006. survey questionnaires and consent forms were posted on the web. select participants the survey url (http://freeonlinesurveys.com/rendersurvey.asp?id=106221) was sent to library staff via library discussion lists along with a consent form including contact information and a brief explanation of the survey’s purpose. the surveys were anonymous and confidential. names, e-mail addresses, and personally identifiable information were not tracked. all participants filled out the survey online. the sample was limited to employees who were at least nineteen years old. directors and department heads were also welcome to participate. instrument data collected for this study included categorical data (i.e., gender and ethnicity) and numeric data (age, years of education, and years of experience). this was an attitudinal survey; hence, the rensis likert scale was used for data feedback. most of the data was quantitative likert scale, such as the preference for online training, the professional development policy, and the budget allocation for training. data collection “entailed measuring the attitudes of employees, providing feedback to participants, and stimulating joint planning for improvement” (swanson 2001). likert-type scales provide more variation of responses and lend themselves to stronger statistical analysis (creswell 2005). it is important to select a well-tested instrument that article title | author 35online workplace training in libraries | haley 35 reports reliable and valid data. however, measuring attitudes has been one of the most challenging forms of psychometric measurement (thorkildsen 2005). due to a lack of similar studies of libraries’ online training, no instruments could be found for this study except the education participation scale (eps), the deterrents to participation scale (dps), and the style analysis survey (sas) instruments. boshier’s forty-item eps (1974) is reliable in differentiating among diverse groups with varying reasons for participating in continuing education (as cited in merriam and caffarella 1999). the eps is used to find the motivations as to why people participate in continuing education; consequently, the eps cannot answer all questions of this study. similarly, the dps reveals factors of nonparticipation; hence, the dps cannot be used in this study. and while the sas is designed to identify how individuals prefer to learn, concentrate, and perform in both educational and work environments (sloan, daane, and giesen 2002), after careful examination, it was found that the sas was not well-suited to this study. because surveys are used to collect data and to assess opinions and attitudes (creswell 2005), the researcher chose to develop a survey that contained about 20 items to assess library staff’s opinions and attitudes toward online training. the survey consisted of three parts: demographic variables, likert-scale assessment of online workplace training preference, and open-ended questions that were worded to reflect reasons for training preference (see appendix). to capture demographic data, participants were asked to indicate their age, years of library experience, years of education (high school/ged = 12; two years college = 14; bachelor’s degree = 16; one master’s degree = 18; two master’s degrees = 20; ph.d/ed.d = 22+), gender (1 = male or 2 = female), ethnicity (1 = asian/pacific islander, 2 = american indian, 3 = african american, 4 = hispanic, 5 = white, non-hispanic, and 6 = other). the likert scale items are designed using a forced-choice likert scale (smith 2006), that is, an even number of response options (1 = strongly agree; 2 = agree; 3 = mildly agree; 4 = mildly disagree; 5 = disagree; 6 = strongly disagree), rather than an odd number (strongly agree; agree; neither agree nor disagree; disagree; strongly disagree). a scoring decision is consistently applied in order to have a meaningful interpretation of the scores. thus, for the likert scale items, the scaling method is to use high scores to represent stronger resistance to a measured attitude of online training. to insure reliability and validity of scores, the questionnaire was reviewed by an expert in the library field to validate if questions were representative of the library field. data collection the way a researcher plans to draw a sample is related to the best way to collect data (fowler 2002). the above sampling approach made it easier for data collection. the author collected data via the web survey company by paying for survey services on a monthly basis. the data was collected by the end of april 2006. the total number of participants was 292 (n=292), of which 260 were valid. thirty-two participants did not complete the survey; those surveys with missing data were excluded from analysis. survey results were saved in a text file and then downloaded into spss for analysis. ■ results and analysis beside general frequency analysis, the kruskal-wallis test was used for six ethnic groups. since some ethnic groups had small sample sizes, all minorities (48) were merged in one ethnic group. thus, the mann-whitney test was used for the two ethnic groups—minority and majority. the author also assessed bivariate relationships with preference of online training and other variables. frequencies analysis frequencies analysis includes demographics, preference of online training versus face-to-face training, budget, and professional development policies. demographics. eighty-five percent of participants were female, 81 percent were white, 49 percent had one master ’s degree, and 23 percent had two or more master ’s degrees. nearly 70 percent were forty years old or older; 45 percent were fifty years old or older. thirty-six percent had less than 10 years of library experience (see table 1). preference of online training versus face-to-face training. most participants (87.3 percent) reported that online training was less effective than traditional face-to-face training. generally speaking, fewer participants (33.9 percent) preferred online training: strongly agree (3.1 percent), agree (13.5 percent), and mildly agree (17.3 percent). more participants (66.1 percent) did not prefer online training: mildly disagree (28.8 percent), disagree (28.1 percent), and strongly disagree (9.2 percent). budget. fifty-five percent of participants somewhat agree their library allocates sufficient budget for training: strongly agree (8.8 percent), agree (25.8 percent), and mildly agree (20 percent). professional development policies. sixty-eight percent of participants somewhat agree their libraries had good professional development policies: strongly agree (13.5 percent), agree (30 percent), mildly agree (24.6 percent). table 2 shows the frequencies of preference of online training, budget, and policy. 36 information technology and libraries | march 200836 information technology and libraries | march 2008 kruskal-wallis test of ethnicity (α = .05) in the kruskal-wallis test for ethnicity, to match the total number of 48 minorities, 48 white people were randomly selected from 212. the test was not significantly different. in the kruskal-wallis test, chi-square is 2.222 (df = 4) and asymptotic significance was 0.715, which was greater than the criterion α = .05. there was no difference in preference for online training between ethnic groups. mann-whitney u test statistics of ethnicity (α = .05) the mann-whitney test of ethnicity was not significant. asymptotic significance is 0.81 (z = -.241), which was greater than the criterion α = .05. there was no difference in preference for online training between the minorities group and the group of white/not hispanic. mann-whitney u test statistics of gender (α = .05) the mann-whitney test of gender was not significant. asymptotic significance was 0.675 (z = -.419), which was greater than the chosen α value (α = .05). there was no significant difference in preference for online training between males and females. bivariate analysis (α = .05) bivariate correlations were computed (see table 3). preference for online training was not associated with age, years of education, years of library experience, sufficient training budget, or professional development policy. it makes sense to believe that traditional face-to-face training has better quality than online training. before the survey analysis, the author expected that younger employees would prefer online training and older ones would prefer traditional face-to-face training due to the older employees’ reluctance to change. it was also expected that highly educated employees would prefer online training while less educated ones, with fewer online skills, would prefer traditional face-to-face training. another assumption was that employees with more library experience would prefer online training while less experienced ones would prefer traditional face-to-face training. the survey showed these assumptions were wrong. it was also assumed that an insufficient training budget might result in a preference for online training, since online training is more cost effective; and that good professional development policies might result in preference for traditional face-to-face training because it is of better quality than online training. the survey found these assumptions to be false. training budget and professional development policies were irrelevant to the preference for online training. however, it was not surprising to find that preference for online training was associated with training providers and training locations, as seen in table 3. ■ discussion the exploration of the relationships among these variables revealed that the preference for online training was not related to demographics, budgets, or professional development policies. however, the preference for online training did show a correlation to training providers and locations. it was surprising to discover table 1. demographic

article title | author 37online workplace training in libraries | haley 37 the preference for online training was not associated with ethnicity, gender, age, education, or library experience. it was interesting to note that training budgets and professional development policies were not related to the preference for online training. several study hypotheses were confirmed. library staff preferred traditional face-to-face training as opposed to online training. although one-third (33.8 percent) of participants preferred (including mildly agree, agree, and strongly agree) online training, only 12.7 percent of participants thought that online training was more effective than traditional face-to-face training. on the other hand, the majority (80 percent) preferred online training when the training was held out of state; 56.2 percent preferred online training when it was held in state. the study concluded that online training was preferred if the training locations required participants to travel great distances from the library. of the participants, 63.1 percent preferred online training when the training was provided by a vendor. some participants did not think face-to-face contact was important for vendor training. this finding suggests that online training is a better choice for vendor training. fifty-five percent preferred online training when it was provided by an association/organization. association/ organization trainers should consider a combination of online and traditional face-to-face training to meet the needs of the majority. online training can be provided for some specific tasks, and supplemented by face-to-face training for others. the following are survey summaries of key reasons to use online and traditional training, along with suggestions from the survey participants. the main reasons to use online training ■ flexible (allows more people from one worksite to participate) ■ saves time ■ eliminates travel cost ■ generally lower training costs ■ ease of access (able to have handson practice with a technology and software program, able to refer back to supplemental materials, able to obtain wider range of training, appropriate to give general overviews in preparation for more indepth face-to-face training) ■ convenient (have some control over one’s time, attend training from the comfort of home or office rather than having to drive somewhere and sit through a presentation, fits easily into a busy schedule, and self-paced in asynchronous online training) the main reasons to use face-to-face training ■ questions and answers: able to ask questions and discuss answers, see immediate feedback, questions others are asking may include some that you didn’t think of, and problems solved directly ■ networking with peers: face-to-face training allows for serendipitous networking opportunities, you have the option of personal conversations with trainers as well as social opportunities to meet other professionals, it is hard to meet people and make friends through an online training, get out of the library once in awhile, find out what experiences staff from other departments or libraries are having ■ better communication and interaction: have personal interaction with instructors and participants, share ideas and experiences with others, enjoy discussions and diversity of personal opinions that come from face-to-face training ■ learn efficiently and effectively: learn from others— not just the instructor, get more out of real training, easy to get disinterested if no face-to-face contact, learn better from an instructor ■ technology barrier: sometimes technology can get in the way of training, some online training was poorly designed, online classes took forever to load and two seconds to read the whole page. suggestions to improve library workplace training administrative support. the most important factor is having library administrators who support training and encourage staff at all levels to attend training. provide workshops for professional librarians and civil service workers that relate to their work, and give them release time for training. library administrators must understand the importance of training and develop training policies with a commitment toward staff development. table 2. frequencies of preference of online training, budget, and policy descriptor frequency mean*

competence and cumulative learning, instead of spontaneous one-shot training for new products or systems. more training. many participants expressed their desire for more training. training not only increases their knowledge and skills needed for their job, but also provides opportunities to network with colleagues. more face-to-face and technical hands-on training are needed since many librarians felt left out of the technology loop. they think that maintaining a current view of developments in technology is difficult. more online training is needed, both asynchronous and synchronous. asynchronous training is good for self-paced training, which is preferred by many survey participants, while some enjoy online webcasts of seminars and workshops for better interaction. it is hoped that state libraries will provide online streaming videos about various topics for academic, private, and public library staff. more funding. make more funding available for library workplace training. the training budget should not be the first thing cut when budgets get tight. a combination of online and traditional face-to-face training. walton (1999) notes that we must ensure we learn and grow. we may learn and grow by participating workplace training. training programs should be built into strategic hrd plans that will best fit employees’ learning preference. this study shows that online training works well with basic informational topics and most technology topics (databases, searching, or web-related technologies). certain simple topics were more appropriate for online training, such as a vendor ’s product and procedural training. some topics do not translate well into online training, however, such as how to conduct storytimes— topics that require a lot of interaction between participants. difficult topics need traditional training for direct answers from the instructor. topics that need in-depth discussion should be provided with traditional training. in other words, provide basic trainings online and save face-to-face training for more difficult topics. ■ future research future research should focus on new learning needs, how people interact with technology, and how people learn in an online environment. more research is needed for a variety of online training. in this study, the generic term “online training” was used. future study needs to expand the term “online training” to static asynchronous online training and interactive synchronous online training. static online training includes text-only static, and textgraphic static with or without voice. interactive online training includes voice-only interactive, and voice-video interactive with ability to ask and answer questions in real time. as time goes by, more people will have taken online training and will be more comfortable with it. as more people have online training experience, their attitudes toward online training may change. further research should examine and measure library staff’s preference for a variety of online training. in addition, participants should be surveyed by grouping experienced online trainees and non-experienced online trainees. finally, studies may be conducted to survey library staff in other countries to compare their preferences with those of their u.s. peers. the goal of this study is to provide helpful information for department heads, supervisors, and library human resources staff to assist them in determining the types of training that will be most effective to meet traintable 3. bivariate correlations with preference of

made available to the world via the web using an inexpensive but highly functional search engine created in-house. the technology consists of a microcomputer running unix to serve relational databases. cgi forms created using the programming language perl offer flexible interface designs for database users and database maintainers. many libraries maintain indexes to local collections or resources and create databases or bibliographies con46 information technology and libraries i march 2000 cerning subjects of local or regional interest. these local resource indexes are of great value to researchers. the web provides an inexpensive means for broadly disseminating these indexes. for example, kilcullen has described a nonsearchable, webbased newspaper index that uses microsoft access 97.1 jacso has written about the use of java applets to publish small directories and bibliographies.2 sturr has discussed the use of wais software to provide searchable online indexes.3 many of the web-based local databases and search interfaces currently used by libraries may: • have problems with functionality; • lack provisions for efficient searching; • be based on unreliable software; • be based on software and hardware that is expensive to purchase or implement; • be difficult for patrons to use; and • be difficult for staff to maintain. after trying several alternatives, staff members at the north dakota state university libraries have implemented an inexpensive but highly functional and reliable solution. we are now providing searchable indexes on the web using a microcomputer running unix to serve relational databases. cgi forms created at the north dakota state university libraries using the programming language perl offer flexible interface designs for database users and database maintainers. this article describes how we have implemark england (england@badlands . nodak.edu) is assistant director, lura joseph (ljoseph@badlands.nodak.edu) is physical sciences

facilitate other such projects . i creating the databases the two databases that we selected to use as demonstrations of this technology are a community newspaper index and a bibliography of publications related to north dakota geology. the forum index the farg o forum is a daily newspaper published in fargo, north dakota. it began publication in 1879 and is the paper of record for north dakota . for many years, the north dakota state university libraries have maintained an index to the forum. beginning with the selective indexing of notable events and editions, we started offering full-text indexing of the entire paper in 1996. until early in the 1980s, all indexing was done manually and preserved on cards or paper. then for several years , indexing was done on one of the university's mainframe computers . starting in 1987, microcomputers were used to compile the index, first using dbase and then using procite as the database management software . printed copies of the database were sold annually to subscribing libraries and businesses . starting in the summer of 1996, th e library made arrangements with the publisher of the paper to acquire digital copy of the text of each newspaper. in early 1997, the ndsu libraries began a project to place all of our forum indexes on the web. dbase, pro-cite, wordperfect, or microsoft access computer files existed for the newspaper index from 1879 to 1975, 1988, and from 1990 to 1996. all other data was unavailable or unreadable. printed indexes from 1976 to 1987 and 1989 were scanned using a hewlett packard 4c scanner fitted with a page feeder . optical character recognition was accomplished using the software omnipage pro. once experience was gained with scanner and software settings, the scanning went very quickly with very few errors appearing in the data. various members of the library staff volunteered to check and edit the data, and the digitizing of approximately 1,500 pages was completed in about three weeks. all data were checked and normalized using microsoft's excel spreadsheet software and then saved as tab-delimited text. programmer's file editor was used to do the final text editing. because of variations in the completeness of the indexing, three separate relational database tables were created: one each for the years 1879-1975, 1976-1996, and 1996-the present. the collective bibliography of north dakota geology in 1996 a project was initiated to combine three bibliographies of north dakota geology and to make the final product searchable and browsable on the web. all three of the original print bibliographies were published by the north dakota geological survey. scott published the first bibliography as a thesis . it is a bibliography of all then-known north dakota geological literature published between 1805 and 1960, and most entries are annotated. 4 the second print bibliography, also by scott, focuses on north dakota geological literature published in the years 1960 through 1979, and also includes some material omitted in the first bibliography .5 most entries in the second bibliography include annotations in the form of keywords or keyword phrases. the third bibliography covers the years 1980 through 1993, and is not annotated.6 all three bibliographies are indexed . the third bibliography was available in digital format, whereas the first two were in print format only. library staff members began rekeying the two print bibliographies using microsoft word. the remaining pages were digitally scanned using a new hewlett packard 4c scanner and the optical character recognition software omnipage pro . there were many errors in the resulting text. different font sizes in the original documents may have contributed to optical recognition errors . editing of the scanned pages was nearly as time consuming and tedious as rekeying the documents . the microsoft word documents were saved as text files and combined as a single text file. programmer's file editor was used as a final editor to remove any line breaks or other undesirable formatting. each record was edited to occupy one line, and each field was delimited by two asterisks . asterisks were used because there were many occurrences of commas, semicolons, and other symbols that would have made it difficult to parse any other way. because italics were removed by converting to a text file, some errors were made in parsing. in retrospect, parsing should have been done before the document was saved as a text file. punctuation between fields was removed because the database would be converted to a large table. it would have been better to leave the punctuation intact, since it cannot easily be put back in for the output to be presented in bibliographic form. the alphabetical additions to publication dates (e.g. baker, 1966a) were left intact to aid in hand-cutting and pasting index terms into the records at a later date. initially, the resulting document was converted to a microsoft access file so that it would be in a table format. however, many of the fields communications i england, joseph, and schlecht 47 reproduced with permission of the

editing interface were well over the 256 character limit of individual fields . to solve this problem, the data were imported into a relational database called mysql, which allows large data fields called "blobs." running under unix, mysql is very flexible and powerful . i database and search engine design we examined the features and capabilities of various online bibliographies and indexes when deciding on our search interfaces and search engine designs . we wanted our databases to be both searchable and browsable and, in the case of the collective bibliography of north dakota geology, we wanted to provide the option of receiving search results accurately in a specific bibliographic format. we wanted both simple and advanced search capabilities, including the ability to do highly sophisticated boolean searching. finally, we wanted to provide those maintaining the databases with the ability to easily add, delete, and change records from within simple forms on the web and immediately see the results of this editing . mysql uses a perl interface, dbi (database independent interface), which makes accessing the database simple from a perl script. essentially, a sql statement is generated, based on data from an html form. this sql statement is then run against the mysql database, returning matching rows that the same script can handle and display as needed. all of the dynamically generated pages in this database are created this way. using both mysql and perl provided a nice, elegant way to integrate database functionality with the web. the databases were installed on a server and made available via the web. it soon became apparent that there were problems with large numbers of returns . depending upon the client machine's hardware configuration, browsers could lock up the 48 information technology and libraries i march 2000 machine. while an efficient search should not result in such a large number of hits, we decided to limit returns to reduce this problem. following suggestions from users, various search tips were added, and some search interface terminology was changed. from a secure gateway , it is possible to call up different forms that allow individual records to be displayed, edited, and saved (see figure 1). new records are added by using a simple html form . it is also possible to bulk-load large numbers of records by using a special perl program to load the data directly from a text file. i advantages of the unix/mysql solution after first using glimpse, a popular web search engine, under linux, a free unix platform, and then microsoft's internet information server (iis) software on a windows nt platform to search the forum newspaper index, we settled on using mysql on a microcomputer running linux and the apache web server. we found we could write perl scripts that allowed users to make very sophisticated searches of the data from within very simple web forms. mysql is stable, reliable, free, and offers a high degree of functionality, flexibility, and efficiency. apache is reliable, extendible, very fast, free, and offers tight control of data access. initially, each story received from the newspaper was maintained as a separate file on a microcomputer. by having the stories as separate files, it was easy to set up glimpse as a searching tool for the articles. although it did provide a nice preview of a workable system, glimpse did not provide enough flexibility in how records were displayed, organized, or searched. it was not meant for managing data of this sort. windows nt, although a popular and successful it solution, was reproduced with permission of the copyright owner. further reproduction prohibited without permission. found to be somewhat cumbersome to implement and did not provide enough flexibility. the installation of these tools was easy, but it was difficult to obtain a high level of database and web integration . reliability and cost were also concerns . we found that unix was more stable and practically eliminated any unavailability of the data . perl, mysql, and apache were ultimately used to manage, store, and deliver the data. although these products are available for windows nt, their native platform is unix. by running these products on unix, we were able to take advantage of all the features offered by each of the products. we found that mysql offered the flexibility and power to manage both sets of data efficiently. also, to load the data into a relational database such as mysql required the data to be normalized. normalized data are data that are separated into logically separate components. to normalize data often takes some extra effort, as fields must be defined to contain certain types of data, but in the end the data is easier to manage and well organized. by having articles and bibliographies in a relational database, we are able to easily make updates, additions, and generate output or reports on the data in many different ways. there are several web servers available on the market today . however, apache is often singled out as being the most popular server . apache, like perl and mysql, is available free for all uses (educational and commercial). using apache and .htaccess control files, we are able to restrict access to administrative pages where data are added or modified. many extensions for apache are available to increase web performance in different situations. for example, a module for apache allows the web server to execute perl code within the server without the need to run the regular perl interpreter. i conclusion and future plans work is under way to refine and update the collective bibliography of north dakota geology. because bibliography number three was not annotated, index terms are being added to facilitate searching and retrieval of citations. we have recently updated the collective bibliography of north dakota geology to include citations to publications through 1998, and we plan to update the database annually. additionally, we receive monthly updates of forum articles, which are added using a simple perl script as soon as they are received. we have successfully implemented a number of other databases using these methods. we realize that this unix/ mysql solution is likely to be most helpful to other academic libraries: there are generally students and staff available on many campuses who are capable of programming in perl and maintaining sql databases on unix servers. our perl scripts are available at the url ww.lib.ndsu .nodak.edu/

one-stop access to key services for learning and academic self-management. this case study reports how instruction librarians at the university of vermont collaborated with portal developers in the registrar’s office to develop high-impact, point-of-need content for a dedicated “library” page. this content was then created in libguides and published using the application programming interfaces (apis) for libguides boxes. initial usage data and analytics show that traffic to the libraries’ portal page has been substantially and consistently higher than expected. the next phase for the project will be the creation of customized library content that is responsive to the student’s user profile. introduction for many academic institutions, campus portals (also referred to as enterprise portals) are one of students’ most frequently used means of interacting with their institutions. campus portals are websites that provide students and other campus constituents with a “one-stop shop” experience, with easy access to a selection of key services for learning and academic self -management. typically, portals provide features that make it possible for students to obtain course information, manage course enrollment, view grades, manage financial accounts, and access information about campus activities. for faculty and staff, campus portals provide access to administrative resources related to teaching, human relations, and more. these campus portals are different from library portals, which some libraries implemented in the 2000s as a way to centralize access to key library services.1 currently, the public-facing websites of many colleges and universities serve a crucial role in marketing the institution to prospective students. this creates an incentive to be as comprehensive as possible and to showcase the full breadth of programs, services, offices, and facilities. a common disadvantage to this approach to institutional web design is information overload: an overwhelming array of labels and links that diminish the ability of current affiliates to find and access the services they need. these sites are designed for external users for whom the research and educational functions of the library are a low priority. campus portals, however, are designed for internal users and can take a more selective approach. they give student and faculty users a view of campus services that aligns with their priorities and places them in a convenient interface. in this sense, they are tools for information management. campus portals play a critical role in students’ daily lives because they do much more than simply present information. carden observes that campus portals have these key characteristics: mailto:graham.sherriff@uvm.edu mailto:ddesanto@uvm.edu mailto:daisy.benson@uvm.edu mailto:gatwood@uvm.edu information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 2 • allow a single user authentication and authorization step at the initial point of contact to be applied to all (or most) other entities within the portal; • allow multiple types and sources of information to be displayed on a single composite screen (multiple “channels”); • provide automated personalization of the selection of channels offered, based on each user’s characteristics, on the groups to which each user belongs, and possibly on the way in which the system has historically been used; • allow user personalization of the selection of channels displayed and the look-and-feel of the interface, based on personal preferences; • provide a consistent style of access to diverse information sources, including “revealing” legacy applications through a new consistent interface; and • facilitate transaction processing as well as simple data access. 2 in sum, enterprise portals use a combination of advanced technologies that have the ability to present both static and user-responsive information in a space reserved for affiliates of the university. these abilities present an attractive venue for libraries to leverage the capabilities of a campus portal to present users with dynamic, personalized instructional experiences—in a space where users are. this aligns with the principles of user-centered design, which emphasizes the need to empathize with users’ needs and perspectives. simplicity, efficiency, convenience, and responsiveness to each user’s individual circumstances are critical.3 the idea of presenting libraries’ content through a campus portal is not a new one. stoffel and cunningham surveyed libraries in 2004 and, while finding that “library participation in campus portals is . . . relatively rare,” of the sixteen self-selected responding campuses, ten had a library tab or a dedicated library channel within their campus portal, while two more had a channel or tab under development.4 the types of library integration described in most examples consisted of using the portal’s campus authentication to link to a user’s library account and view borrowed books, fines, holds, and announcements. while resources like federated searches, research guides, and lists of journals and databases appeared in some respondents’ portals, they largely appeared as static content rather than responding to the user’s profile. since 2004, portals have remained a core part of the university of vermont’s information delivery system, but portal integration remains relatively rare among libraries and most have done little to integrate new tools such as research guides or develop instructional content that leverages a portal’s user-responsive design. as a result, there is little in the literature on libraries’ integration of content into campus portals, but a small number of case studies provide proof of concept, such as lehigh university, california state university-sacramento, and arizona state university.5 these case studies also illustrate the importance of cross-campus collaboration. our project required some critical elements, specifically access to the campus portal and a method for publishing content. the projects described in the case studies were successful partly because they were able to apply advanced programming expertise that was not available to our group, such as api coding. instead, our group was able to obtain these critical inputs through a partnership with the university of vermont registrar’s office. information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 3 at the university of vermont, the campus portal uses the banner product licensed from ellucian and has branded it as “myuvm.” it is administered by the registrar’s office. librarians have observed that it is central to students’ academic lives. students go to myuvm as their pathway to many of the online services and tools that they use. they go there to check email, log in to the learning management system (lms), check grades, to add, drop, or withdraw from courses, to check their schedule, and more. they go there to carry out tasks. figure 1. screenshot of myuvm (https://myuvm.uvm.edu as it was on march 1, 2019). the importance of myuvm is communicated to university of vermont students at orientation. in this way, first-year students learn at the earliest point, even before their academic programs begin, that the portal is their primary gateway for access to campus academic services. this shapes their view of the services available to them and how those services are organized. it also shapes how they reach those services and how they interact with them. at the same time, the selective principle underlying the campus portal means that if something is not present, it is less visible and less accessible, and there is a risk of signaling to students that it is not important to their daily lives or their academic performance. methods the characteristics of campus portals and their contents motivated instruction librarians to explore the possibility of integrating library services into myuvm. in 2014, the university of vermont libraries’ educational services working group—a small cross-libraries group of librarians who work on a variety of projects supporting classroom instruction and research assistance—began by defining the desirable scope of possible portal content. https://myuvm.uvm.edu/ information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 4 the educational services working group quickly determined that library content included in the portal should be designed to conform with the principle of priority-based selectivity employed across the portal as a whole. this content should not attempt to represent the full s uite of library information and services available. this would replicate the websites of the three libraries on campus and would risk creating overload and disorientation, in a similar way to institutional websites. it is common for actionable and instructional material to become buried beneath links on a library homepage, and the homepages of our three libraries’ websites are no different. our hope was to reposition selected instructional content such as research guides, databases -bysubject, chat reference, and liaison librarian contacts in a venue with which students are used to interacting. the goal of the project was the strategic positioning of dynamic, responsive information about research services in a venue with which students frequently interact. research librarians would select and organize the most important and pertinent instructional content. such selectivity fit well within the portal’s principle for curating content: high-use tools and services that directly support students’ priorities. thus the objective for this project would not be the re-creation of the library websites within myuvm. it was also determined that the scope would exclude content that might be considered marketing or engagement for its own sake, for the same purpose of minimizing users’ cognitive load and helping them to quickly find the features they need. the myuvm developers in the registrar’s office were enthusiastic about working with us on this project, which partly reflects an increased attention across campus to equitable access to student services for all users—something that is important for its own sake, but also for the purposes of accreditation. following preliminary discussions in early 2018, myuvm developers created a test “libraries” page, equivalent to a full screen of content, and assigned to our group the privileges necessary to view it in the myuvm test environment. each page in myuvm is composed of a series of content boxes or channels. in developing our new page, our task was to develop content for the desired channels. we began our process for composing the page with a card-sorting exercise that identified priorities for the content that should be highlighted. the participants were the group’s members, in order to expedite initial decisions about content that could be tested with users at a later point in the project. items that figured prominently in this process were the libraries’ “ask a librarian” service, research guides, and search tools (discovery layer, databases, and journal directory). this confirmed that our group’s priorities centered on users’ transactional interactions with library services and not merely the one-way promotion of library information. the results of the card sorting were then translated into a wireframe (see figure 2). each square in the wireframe represented a channel for which we would need to create the appropriate content: • ask a librarian (contact details for the libraries’ research assistance services) • research guides (subject and class guides) • search our collections (search tools for the discovery layer, databases, and journal directory) information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 5 • research roadmap (the libraries’ suite of tutorials on foundational research skills) • featured content (a channel for rotating or temporary time-specific content) • libraries (a box with a link to each of the three libraries on campus; we later added a channel for each library) • the wireframe also envisaged the inclusion of a pop-out chat widget. figure 2. wireframe for library content. as noted, the project needed a process that would enable our group to create and publish this content autonomously, but without requiring advanced programming skills on our part. we learned that myuvm is capable of publishing content pushed from a webpage by using its url. this meant that we could create content in libguides, a platform with which our group was very familiar, and then push the content of an individual libguide box to a myuvm channel simply by providing the libguide box urls to the portal developers. this method offers several advantages. importantly, it meant that our group had direct control of the box content and was able to publish it without needing the myuvm developers to review and authorize every edit. information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 6 those involved in this project faced important decisions early in the process regarding which resources we deemed essential for inclusion and best suited to this new online context. once items were selected, it was important to keep user behaviors in mind as we prioritized “above the fo ld” content. students are used to quickly popping into the portal, finding what they need, and popping out. we tried to place interactive content that fit this use pattern in high-visibility places and moved content that required more sustained reading and attention further down the page. a challenge faced during the design process was our campus’s lack of a unified, cross-libraries web presence. the three libraries on our campus have separate websites, but the university of vermont portal required that we present a unified “libraries” presence. in some cases, such as links back to library webpages, we were easily able to treat the three libraries separately. in other cases, such as our research guides, we were able to merge resources from multiple libraries. in still other cases, such as our chat widgets, we had to make decisions about which library’s resource would be featured and which other versions would be secondary. the prototyping and testing phases revealed that some content needed to be adjusted in order to display in myuvm as desired. libguides’ tabbed boxes and gallery boxes did not display correctly. also, some style coding inherited from the libguides boxes needed to be adjusted in order to display cleanly. one item, “course reserves,” was present in the wireframe but not the page at the time of implementation. we continue to work on the development of a widget for searching “course reserves” holdings. the version of the “library” page at the time of going live is shown in figure 3. figure 3. screenshot of the “library” page in myuvm. the “research guides” channel has a dropdown menu for subject guides and another for class guides. these menus were created using libguides widgets, meaning that they update automatically as guides are published and unpublished, and do not require any manual maintenance. information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 7 the “search our collections” channel includes three access points to the libraries’ collections. this contrasts with the libraries’ websites, which display only the discovery layer search box. the latter approach has the advantage of promoting one-stop searching, but also the disadvantage of overwhelming users with non-relevant results. channels on the left side of the page are less dynamic and interactive. at the top, links to the three libraries on campus provide highly visible quick access for students looking for the libraries’ websites. similarly, the “ask a librarian” channel quickly gets students to reference and consultation services at their home library. the “you should know” channel provides a space for rotating content to be changed based on time-of-year, events on campus, or other perceived student needs. results the “library” page in myuvm went live in january 2019, at the same time that spring semester classes began. our preliminary review of results from the semester, based on data collected from myuvm, libguides statistics, and google analytics, has identified several positive outcomes. myuvm data showed that there were 18,891 visits to the “library” page during the period from mid-january to the end of march, a period of eleven weeks when classes were in session. this volume of traffic substantially exceeded our group’s expectations for the first months following implementation, during a period when we were only beginning to promote awareness of the page. data also showed that usage during this period was generally consistent. the most significant variation in traffic was a small peak in late february that corresponded with a high point in the level of library instruction. libguides statistics showed an overall increase in usage of subject guides, though it is not possible to attribute this to the myuvm project with complete certainty. in addition, however, we also observed that for many of our guides during this period, myuvm was among the top referring sites. libguides statistics also recorded unexpectedly large increases in usage for the “research roadmap” that we attribute primarily to the myuvm project. four sections of the “research roadmap” experienced increases of more than 100 percent during the january-march period. the research roadmap’s “more help” page showed a 65 percent drop in visits, but a possible explanation for this is that the highlighting of sections in myuvm is providing more-immediate help to our users in finding what they need and promoting independent use of instructional materials by students. libchat statistics indicated a significant increase in chat reference transactions at howe library, the university of vermont’s central library: a 23 percent increase over the count for the fall 2018 semester, with the implementation of the myuvm project being the only reasonable explanation. all initial data appear to show that users are finding and continuing to use the “library” tab in the portal. they are discovering guides and using the embedded chat widget. we plan to gather more usage data for other channels on the page to better inform our picture of what users are doing once they find and view the “library” tab. as campus portals have become a ubiquitous part of university life, revisiting the library’s role in these portals seems worthwhile, especially given that information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 8 commonplace design tools like libguides dramatically lower the technological acumen needed for creating content. future directions the next step for this project is to leverage the ability of a campus portal to create a myuvm homepage library channel that customizes the display of content, based on unique user characteristics. when the user logs in, they are routed to the portal’s landing page, which is dynamically created based upon their student or faculty status, enrollment in a college or school, level of study (graduate/undergraduate), or number of years attending the university of vermont. this page has the ability to conform to the user in even more granular ways and dynamically display content based upon their major or other demographic categories such as study abroad status, veteran status, or first-year students. by leveraging the portal’s ability to display user-specific content, the university of vermont libraries have the ability to customize instructional content tailored to a user’s information needs and place that content in a channel that will display alongside other channels on the myuvm homepage. a first-year history major’s library channel could contain tutorials on working with primary sources, a link to their liaison librarian, links to digitized newspaper collection, and help guides for chicago citation style. a graduate student in nursing might see information abou t evidence-based practices for developing a clinical question, help guides for using pubmed and cinahl, and resources for point-of-care. a faculty member in psychology might find tutorials for creating alerts in their favorite journals, information about copyright and reserves material, or information about citation-management software. in each case, the portal pushes resources and assistance to each user that best fits their specific need, as informed by the librarians best equipped to address that need. this last step of placing dynamic content on the myuvm homepage will require a great deal of coordination with liaison librarians both to identify the most pertinent disciplinary information to place in the portal and to identify the times of year when certain information is most relevant. to keep portal content dynamic and pertinent to users, a system will need to be created for releasing and removing content on a regular basis and this scheduling of content will require the input of liaison librarians. the educational services working group will need to manage this scheduling, as well as the enforcement of portal design conventions in coordination with the myuvm developers. although this management may end up being complex, it is not insurmountable, and our next steps will be to both to create a system for content creation and management, and to begin to create test content for a sample of user groups. we also plan to gather more data and expand our analytics capabilities to assess how users are using content on the myuvm “library” page and examine which features are most popular, how much traffic is being driven back to our websites, and how users are interacting with the features on the page. conclusion our project has confirmed our initial inclination that students go to myuvm as a finding tool for finding inter-campus resources. also, faculty have reported accessing library resources through the portal and directing their students to that pathway as well. the immediate high use and consistency of use indicate that we have placed our selected libraries resources in a high -traffic information technology and libraries march 2020 meeting users where they are | sherriff, desanto, benson, and atwood 9 venue. instead of attempting to coax students to our

acknowledgements endnotes september_ital_varnum_final editorial board thoughts: content and functionality: know when to buy ‘em, know when to code ‘em1 kenneth j. varnum2 information technologies and libraries | september 2017 3 we in library technology live in interesting times, though not those of these apocryphal curse. no, these are interesting times in the best possible way. where once there was a paucity of choice in interfaces and content, we have arrived at a time when a range of competing and valid choices exists for just about any particular technology need. data and functionality of actual utility to libraries are increasingly available not just through proprietary interfaces, but also through apis (application programming interfaces) that are ready to be consumed by locally developed applications. this has expanded the opportunity for libraries to respond more thoughtfully and strategically to local needs and circumstances than ever before. libraries are faced with an actual, rather than hypothetical, choice between building or buying fundamental user interfaces and systems as the internet has evolved, and coding has become more central to the skillset of many libraries, the capability of libraries to seriously consider building their own interfaces has grown. how does a technologically capable library make the decision to buy a complete system or build its own interface to existing data? the process can be decided using a range of criteria that can help define the library’s need for a locally managed solution. we’ll start by discussing technological capabilities needed to take on almost any development project, then define three criteria, and finally discuss the circumstances in which a build solution might be appropriate. the goal is outline a process for deciding when it make more sense to buy both the interface and the content, to build one or the other locally, or to build both. criterion 0: what are the shortand long-term technological capabilities of the library? clearly, the first point of consideration is whether the institution has the capacity to manage application development and user research. the short-term answer may be no, but the long-term answer -one based on the library’s strategic direction -may be that these skills are needed to meet the library’s goals or strategic vision. one project may not be enough to tip the scales, but if the library is continually deciding if the immediate project under discussion is the one to change the balance, then perhaps the answer is that it’s time to invest in new skillsets and capabilities. there are actually several skillsets needed to undertake development projects. individuals with coding skills are needed to adapt existing open-source software to the library’s needs — it is a rare 1 with apologies to kenny rogers 2kenneth j. varnum (varnum@umich.edu), a member of the ital editorial board, is senior program manager for discovery, delivery, and library analytics at the university of michigan library, ann arbor, mi. editorial board thoughts | varnum https://doi.org/10.6017/ital.v36i3.10087 4 open-source project that does exactly what a library needs it to do, with connectors to all the same data sources and library management tools already perfectly configured by somebody else — but that is not sufficient. a library also needs people with user interface and user research skills ensure that the application meets at least the critical needs of its own user community, and does so with language and cues that match user expectations. even if there is not a permanent capability on the library’s staff, development can take place with contract services. if this is the option selected, a library would do well to make sure that staff are sufficiently trained to make minor updates to interfaces and applications, or that a longer-term arrangement is made for ongoing maintenance and updates. criterion 1: what is the need to customize interactions to local situations? most, but not all, applications offer opportunities to match interface features and functionality with local user needs. the more interactive and core to the library’s service model the tool is, the more likely the tool is to benefit from customization. for example, a proxy server -technology that allows an authenticated user to access licensed content as if she were in the physical library or within a campus on a defined network -has little or no user interface. there is little need to customize the tool to meet user needs, beyond ensuring the list of online resources and urls subject to being proxied is up to date. there really aren’t any particularly useful apis to consumer and reproduce elsewhere, and there are easier ways to build an a-z list of licensed content than harvesting the proxy server’s configuration lists. in contrast, the link resolver -technology that takes a citation formatted according to the openurl standard and returns a list of appropriate full-text destinations to which the library has licensed access -may well be worth bringing in house. some vendors offer their software to be run locally, while others provide api access to the metadata. at my institution, we used the apis serials solutions makes available for its 360 link api to build our own interface using the opensource umlaut software. (see https://mgetit.lib.umich.edu/). why go to the trouble of recreating an interface? for several reasons, some of which (understanding user behaviors and maintaining control over user data to the extent practical) i’ll touch on in the following two sections. the main reason centered on providing a user interface consistent with the rest of our web presence, offering integrations to our document delivery service, and a way to contact our online chat service, and a way to report problem links directly to the library when the full text links provided by the system do no work. while these features are generally available through vendor interfaces, the user experience is hard to make consistent with other services we offer. criterion 2: what are the needs for integration with other systems from different providers? integrations can run in two directions: from the system under consideration to existing library or campus/community tools, and from those environmental tools to the library. when thinking about the buy-or-build decision, understanding the scope of these integrations up front is important. if all of the tools or services that need to consume information from or provide information to your information technologies and libraries | september 2017 5 system rely on well-defined standards that are broadly implemented, this criterion may be a wash; there may not be an inherent advantage to building or buying based on data exchange. if, however, the other systems are themselves tricky to work with, relying on inputs or providing outputs in a non-standard or idiosyncratic way, this situation may swing the pendulum toward building the system yourself so you can manage. for example, many course management systems on academic campuses can consume and provide data using the lti [learning tools interoperability] standard for data exchange. many traditional library applications do, as well, so if a library using an lti-compliant system needs to provide course reserves reading lists to the course management system, this is a ready-made way to make that information available. at the other extreme, bringing registrar’s data into a library catalog -to know who is in what courses to provide those patrons with an appropriate reference librarian contact for a particular subject, or access to a reading list through a course reserves system -may only be possible through customized applications to read non-standard data. in this case, to provide the desired level of service to the campus, the library may need to build local applications. criterion 3: who manages confidentiality or privacy of user interactions? a final, and increasingly significant, criterion to consider is where the library believes responsibility for patron data and information seeking behavior to reside. notwithstanding contractual or licensing obligations taken on by library vendors, the risk of inadvertent exposure or intentional sharing of user interactions is always present. one advantage of building local systems to interact with vendor systems (link resolvers, discovery platforms, etc.) is that vendor does not have access to the end-user’s ip address or any other personally identifying information. the vendor only sees a request coming from the library’s application; all requests are equal and undifferentiated. of course, once users access the target item they are seeking (an online journal, database, etc.), that particular vendor’s site has access to that information. for libraries concerned about user privacy, the risk of exposure is somewhat mitigated by managing the discovery or access layer in-house -and deciding to maintain a level of user information that suits that particular library’s comfort level -and potentially minimizing the single point of failure for breaches. at the same time, such a decision puts more responsibility on the library or its parent information technology organization to protect data from exposure. some libraries feel they can handle this responsibility -either by careful protection of the data, or by not collecting and storing it in the first place -in a way that library vendors cannot. concluding thoughts making the buy-or-build decision is not straightforward; the criteria described here are not the only ones a library might wish to consider, but they are common ones with the greatest ramifications. putting the decision process into a framework can help a library make consistent editorial board thoughts | varnum https://doi.org/10.6017/ital.v36i3.10087 6 decisions over time,

between research management systems, especially digital libraries or repositories, has been a central theme in the community for the past years, with the discussion focused on means of enriching, linking, and disseminating outputs. this paper considers a frequently overlooked aspect, namely the migration of records across systems, by introducing the stateful library analysis and migration system (slam) and presenting practical experiences with migrating records from dspace and digital commons repositories to figshare. introduction bibliographic record repositories are a central part of the research venture, playing a key role in both the dissemination and preservation of outcomes such as journal articles, conference papers, theses and dissertations, monographs, and, more recently, datasets. as the ecosystem of which these are a part of has evolved at a sustained pace in the last decade, repositories also had to adapt while ensuring uninterrupted service to the research community. nevertheless, a number of developments, both at the local, repository level and at a more general, global scale, have created the necessity of considering the complete replacement of certain systems with new repository solutions which are better suited for their stakeholders’ requirements. the following are a few such developments: • the need to consolidate both technological solutions and operational teams, in order to reduce running costs and provide a unified experience for end users, the research personnel.1 • various policies require researchers to provide not only traditional outputs, such as journal articles or conference papers, but also the datasets and other materials backing up scientific claims. for repositories, this means both adapting to larger amounts of stored data as well as ensuring that the metadata dissemination and preservation mechanisms are suited for the new output types (e.g., while full-text search is a common feature of literature repositories, it cannot be easily applied to numeric datasets).2 • apart from extending the set of stored outputs, policies have also created new requirements for existing record types. for example, the research excellence framework (ref) in the uk mandates monitoring open access (oa) publishing of research articles; thus, institutional repositories are no longer only a facilitator of green open access (selfarchiving of records) but also a means of monitoring compliance.3 this requires the implementation of new logic in existing repositories, which can frequently be difficult, especially when faced with legacy repository code bases or insufficient technological resources. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 2 • commercial, contractual, or leadership changes can also create the need to replace repository systems, due to uncertainty (see the acquisition of bepress by elsevier) or preference for certain platforms.4 while these developments can generate the requirement to switch repositories in a very short span of time, such a venture needs to be properly planned and executed in order to ensure, on the one hand, that no records are lost or corrupted and, on the other hand, that minimal or no downtime is caused. ideally, migrations would also be an opportunity to curate and enrich the existing corpus by consolidating and correcting bibliographic records. between 2018 and 2019 the research team has performed six digital library migrations from various source repository solutions (dspace, digital commons, custom in-house built systems) to the figshare software as a service (saas) repository platform. for this purpose, slam, an extract, transform, load (etl) system, was developed and successfully employed in order to migrate over 80,000 records. this article describes the rationale behind slam, its design and implementation, and the practical experiences with employing it for repository migrations. a number of future enhancements and open problems are also discussed. motivation and background of slam in early 2018 figshare started considering the suitability of its repository platform for storing content which is usually specific to institutional repositories (journal articles, theses, monographs), along with non-traditional research outputs (datasets or scientific software).5 while feature-wise this was validated by its hosted preprint servers, a new challenge was posed, as stakeholders choosing to use figshare as an institutional repository also had to transfer all content from their existing systems.6 thus, in the first half of 2018, a first migration was performed, transferring records from a bepress digital commons (dc) repository (https://www.bepress.com/products/digitalcommons/) to figshare (https://figshare.com). from a technical point of view, a python (https://www.python.org/) script was developed for this migration; this script parsed a commaseparated values (csv) report produced by dc which contained all metadata and links to the record files.7 using this information, records were created on the figshare repository using its application programming interface (api) (https://api.figshare.com). while this migration succeeded, the naive technical solution presented a number of issues: • difficulties with the metadata crosswalk: while a crosswalk was initially set up, mostly based on the definition of the fields in the source and target repositories’ metadata schema, issues were discovered while migrating the records, mainly generated by inconsistencies in the values of the fields across the corpus. these issues were fixed on a case-by-case basis, in order to ensure a lossless migration, but it would have been preferable to surface them in the early phases, in order to have the migration script mitigate the issues in the final run. • running the migration procedure multiple times: the migration script followed mostly an all or nothing approach, which, at each run, fully migrated all records between repositories. this is undesirable, as there was a need to run the script only for those records that failed to migrate (due, for example, to metadata crosswalk issues). after the full migration was completed, there was also a need to apply only some minor corrections to records, without following the full procedure. this was not possible, since the script would recreate all records to migrate from scratch on the target repository, as it did not have any memory of information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 3 previous runs. this issue was also amplified by the fact that in the source repository records did not have any type of persistent identifier attached. thus, additional scripts, which only performed the corrections, had to be developed. • ability to run the migration procedure with minimal supervision: like most migrations, this instance considered a large number of records (over 10,000) and, ideally, the process would run with minimal supervision operators. while the script partially accomplished this, the need for better fault-tolerance and enhanced logging was identified. given the lessons learned from the initial attempt and the requirement that five additional migrations were to be completed between october 2018 and december 2019, a more robust alternative to the naive migration script was required. this alternative had to adhere to three design principles: 1. reusability: the system should be usable for multiple migrations without extensive additions or modifications. thus, it should be able to adapt to the workflows of multiple repositories, metadata schemas, and other concerns specific to each migration. 2. statefulness: in software engineering, programs can either discard knowledge of past transactions or preserve it, allowing previous results and operations to be revisited. migration systems benefit from a stateful architecture, as the system should be able to perform the same migration multiple times, without creating duplicate records on the target repository, while allowing for incremental record improvements with each run. apart from allowing for corrections to be applied post-migration, this would also support the prototyping phase (where multiple test migrations are performed in order to validate the metadata crosswalks), that no information is lost, and other general workflow aspects. 3. fault tolerance: the system should implement fault tolerance mechanisms at all levels, allowing it to run migrations of large corpora with minimal supervision and, at the same time, implement sufficient logging and exception handling to allow operators to identify and correct potential issues. several repository migrations are represented in the literature. in van tuyl et al., the authors describe the process of moving from a dspace (https://duraspace.org/dspace) to a samvera (https://samvera.org) system, while in the study from do van chau records were migrated from a solution developed in house to dspace.8 both instances offer valuable insight into the challenges posed by digital library migrations, especially at the level of bibliographic metadata; on the other hand, both works are focused mostly on a specific use-case and do not propose general technical solutions for other migrations. it is interesting to note that the migration presented by van tuyl et al. required two and a half years of work, while slam was employed to carry five migrations in 14 months. the bridge2hyku toolkit (https://bridge2hyku.github.io/toolkit) is a collection of tools, including a module for the hyku repository solution (https://hyku.samvera.org), aimed at facilitating the import of records into digital libraries based on this software. similar to slam, it includes an analysis component, useful for surfacing and correcting potential metadata issues during the migration. slam provides two major improvements over this solution, namely it defines a generic architecture that can be used for migrating records between any two repositories, while also defining a procedural migration workflow to create a robust, fault-tolerant, and extensible solution. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 4 pygrametl (http://chrthomsen.github.io/pygrametl/) and petl (https://github.com/petldevelopers/petl) are two open-source frameworks which allow the defining of etl workflows; similar to slam, the processing steps are defined using python functions. these projects are targeted towards tabular and numeric data, making them unsuitable for the transfer of files and metadata across bibliographic repositories. singer (https://www.singer.io/) is an etl framework similar in design to slam, which allows the composing of various data sources (or taps) and targets, in order to move data between them. the two downsides of this implementation are that it is focused on processing data specified in the javascript object notation (json) format, which is not always available for bibliographic metadata, and that it does not facilitate extending the pipeline with, for example, the analysis facilities targeted by slam. hevo data (https://hevodata.com/), pentaho kettle (https://github.com/pentaho/pentahokettle) and talend open studio (https://www.talend.com/products/talend-open-studio/) are etl frameworks which employ graphical interfaces to allow users to define the processing workflows. while such functionality was not initially identified as a requirement for our planned migration projects, during testing it became obvious that providing such an interface could bring value by having repository administrators be more involved in defining and validating the processing applied to bibliographic records, as the administrators possess the most knowledge of the organisation of the repositories. a downside of the three solutions is that their usage requires commercial agreements, which did not line up with the business requirements of the considered migrations. in their work, tešendić and boberić krstićev use the pentaho suite in order to implement the etl component of a business intelligence (bi) solution for reporting on bibliographic records.9 while the structure of the etl processing is different—the authors being mostly interested only on certain aspects of the metadata—this work provides insights into the types of analysis that could be performed while migrating records. slam’s design and implementation following the design principles previously mentioned, slam’s architecture was devised as presented in figure 1; as for most etl systems, the easiest way of understanding its operation is by examining the data flow. the migration workflow proceeds by extracting all the required information from the source repository. this could be achieved in multiple ways, such as harvesting through an oai-pmh (https://www.openarchives.org/pmh/) endpoint or other types of api, using the bulk export functionality implemented by most repository systems, or even by crawling the html markup describing records, similar to what search engines do in order to discover web pages. once this mechanism has been established, practical experience proves that it is beneficial to move this raw data closer to the destination repository (to a staging area as depicted in figure 1). while this transfer might prove cumbersome, especially for large corpora, it is required only once. moreover, having the data close to the destination repository allows faster prototyping and testing of the migration procedure, as network latency and throughput are improved, while also ensuring that the source repository’s functioning is not affected in any manner. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 5 figure 1. main components and data flow in slam. areas in light blue are currently under development, while the components highlighted in green need to be adapted for each migration. the system splits the data to be migrated into four logical slices: bibliographic metadata, record files (e.g., pdfs of journal articles), persistent identifiers of records (pids, such as digital object identifiers or handles), and usage data (views and downloads). metadata is the first aspect to be considered. from the migration point of view, two dimensions are considered: the syntax and the semantics. metadata comes in various formats, such as csv or extensible markup language (xml) files, but most of these can be easily parsed by openly available software solutions. of more interest are the semantics of the metadata, which stem from the employed schemas or ontologies of field definitions; examples include dublin core (https://www.dublincore.org) or datacite (https://schema.datacite.org). a schema crosswalk, which describes how the fields in the target repository schema should be populated using the source data, needs to be set up when transferring records. while this should not be a concern if information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 6 the two repositories use the same schema, for the performed migrations (described below) this was not the case. other reasons for setting up such a crosswalk include • loosely defined schema in at least one of the repositories: certain repository systems do not specify a schema with clear field definitions, validations or applicability. by having the source repository administrators help with setting up a crosswalk, the migration team can avoid issues caused by incomplete understanding of the metadata. • support for the review of bibliographic records: migrations can prove to be an opportunity for reviewing and amending the records’ metadata; for example, infrequently used fields can be completely removed, and values which tend to confuse end users can be moved to other fields. • ensuring that a record on how the migration was performed, from the metadata point of view, is maintained. the crosswalk is considered an artefact of the migration and is preserved for future reference. in slam, the crosswalk is tested using elasticsearch, “an open-source search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured.”10 the setup uses the crosswalk to create elasticsearch documents which include all fields as they would be transferred to the destination repository. a kibana (https://www.elastic.co/products/kibana) dashboard is then used to inspect the records’ metadata and perform structured searches across the corpus. this can allow, for example, discovering fields which do not follow a consistent pattern for the values, as seen in figure 2. as the crosswalk includes, apart from the field mapping, altering operations that can be performed on each field, this analysis can facilitate the review process described by the second point above. while performing actual migrations, a number of inconsistencies that the source repository administrators were unaware of were surfaced by slam and corrected in the target repository. this is commonplace especially in large corpora spanning decades, where the repository metadata workflows and schemas changed multiple times. two points should be noted about this component: • this is the only component of the architecture for which we mention an actual solution chosen for the practical implementation, namely elasticsearch. while other solutions could have been chosen, such as the ones included in the bridge2hyku toolkit, elasticsearch proved to be the best fit for a highly automated system which requires analysis capabilities; it is a production-grade solution which can index a high number of documents and support complex queries, while also providing user-friendly analytical views via kibana. • there are arguments for loading the metadata in the analysis component without having it processed through the crosswalk; such a workflow could provide further insights into various issues in the corpus which are possibly obscured by the crosswalk. our practical experiences did not fully justify this requirement, while the actual implementation provided a mean to test the crosswalk, a major migration component; nevertheless, we are still considering the possibility of having to load the raw metadata for analysis in future migrations. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 7 figure 2. a view examining the possible values of the temporal coverage field from the dublin core schema in an institutional repository corpus to be migrated. this shows variation in the format of the values (full date, year only) which can cause issues when migrating to a schema which applies strict validation on date/time values, and thus need to be handled by the migration harness. this view is generated using kibana from the elasticsearch stack, employed by slam for metadata analysis purposes. with the crosswalk set up, the migration module can be completed. from a logical point of view, it comprises of four components: 1. metadata processing: this component uses the crosswalk in order to transfer the metadata to the target repository. 2. file upload: this simply uploads all files associated to a bibliographic record to their new locations. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 8 3. usage data transfer: most repositories implement counters for views and downloads of records, and this information, if available, is also transferred to the target repository. 4. persistent identifier update: if the records are using persistent identifiers, such as digital object identifiers (dois) (https://doi.org/) or handles (http://handle.net/), these are updated to resolve to the new locations in the target repository. while employing slam for migrations, cases in which persistent identifiers were not employed on source repositories were encountered, with records being accessible only via uniform resource locators (urls). as these cannot always be transferred across repositories, because each software uses its own url schema, it is advisable to implement persistent identifiers before migrations. figure 3. a simplified process diagram describing the steps required for migrating a bibliographic record. each successful operation is recorded in a persistent database which is used in subsequent runs for resuming the workflow. for example, files will not be uploaded each time the script is run, thus avoiding duplication. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 9 one of the architectural goals of slam is statefulness and this is implemented at this level, the migration module being designed as a state machine. a trivial example of such a state machine is shown in figure 3. the state machine status is serialised in a persistent database, with each migration run deserializing it in order to understand which operations still need to be applied for each record. maintaining such a registry provides several other benefits: • facilitates testing and prototyping: this was the original reason behind the architecture, useful especially before the metadata analysis functionality was implemented. if one of the operations required for transferring a record fails, subsequent runs will not apply all steps, but only the ones that did not complete. as for each record a separate state section is maintained, this becomes especially useful when migrating multiple entries; records which failed to migrate can be easily isolated and subsequently reprocessed. • allows creating reports on the migration: these are used, for example, to validate that all records were indeed transferred to the target repository. • allows the migration module to be portable: if the state machine serialisation is accessible, the module can run from different locations and at different points in time. the first architectural principle previously presented relates to the reusability of slam across migrations. the most common cause of divergence between migrations is related to the differences between repository solutions; slam isolates this concern by using two connectors, one for the source and one for the target repository. these connectors translate the information to be migrated to and from slam’s internal data model. thus, the source connector needs to be able to traverse the staging storage and provide slam with all the required record information, while the target connector will upload the records to the new repository (using a web-accessible api for example). this means that for each migration only three parts of slam need to be adapted (shown in green highlights in figure 1): the source and target connectors, and the metadata crosswalk. all other components can remain unchanged, thus reducing the technical development time. in the last step of slam’s workflow, the information that was used for the migration is sent to a long-term preservation storage, in order to ensure that it remains available for future reference. in our implementation, the following information is preserved: • original metadata and files, as extracted from the source repository. • metadata crosswalk from source to target repository. • migration script state machine serialisation. this information is sufficient for understanding the exact steps applied during the migration and, if required, for applying certain corrections to the migrated records at a future point in time. employing slam for real-world migrations slam was used for performing five repository migrations in one year, as described in table 1; the target repository in all five cases was figshare. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 10 table 1. overview of repositories migrated to figshare

reuse as much of the system as possible across migrations. the architecture isolated the parts that required adaption from one migration to another (the connectors and the crosswalk); the time spent by a software engineer in order to set up these was monitored. the target here was to support the specialised staff on making domainspecific decisions, especially on the metadata crosswalk, by reducing the time needed to develop the three mentioned components. for example, the research excellence framework (ref) 2021 exercise in the united kingdom had strict metadata requirements, which required thorough testing in connection with current research information systems and open access monitoring solutions. between the first and fourth migration, this was reduced from six person-weeks to only two; it is important to note that slam evolved between the migrations, based on the lessons learned from each instance. statefulness, the property which allows re-processing already-migrated records, is covered in slam by the state machine implemented in the migration module, which is persistent and can be referenced in subsequent runs. all the migrations in table 1 required supplementary runs after all records were migrated, most frequently in order to fix metadata issues discovered after the full corpus was transferred. for example, ir1 required three such runs: 1. the first run fixed a number of issues caused by omissions in the metadata schema crosswalk. 2. the second run enriched the metadata using information taken from a current research information system (a source external to slam). 3. the last run corrected the usage statistics (view and downloads) which were incorrectly imported initially, due to incomplete understanding of the source repository’s database. due to slam’s design, no issues were encountered while performing these runs, as no records were duplicated, removed, or erroneously modified; this was manually checked by the repository administrators, either by sampling the corpus or by inspecting each migrated record, depending on the repository size. a key aspect highlighted by the requirement to reprocess migrated records relates to the granularity of the state machine. as an example, in ir3 a second run required attaching supplementary files to a number of migrated records, and this posed a challenge due to the fact that the state machine only recorded if all files have been uploaded, and not which files were successfully added to the record. thus, the state machine was amended to record the complete list of record files, allowing for more granular control over this processing step. information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 11 the last concern, fault tolerance, was achieved by applying basic software engineering principles, such as fail-fast (report migration issues as soon as they manifest), the implementation of proper exception handling (such as not to ignore any potential issues), and addition of enhanced logging in order to provide a complete record of the processing steps. for each of the five migrations, slam ran unsupervised, reporting at the end of each run the records for which an issue was encountered. as an example, in the ir4 migration, slam initially failed to migrate 300 records. these were reported to the operator, and after minor fixes were applied to the metadata crosswalk the migration completed successfully. fault-tolerance plays a central role in ensuring that during migrations no data is lost or corrupted, by surfacing any edge-case that might have been missed during the development of the metadata crosswalk, repository connectors, or core migration module, while also isolating such issues to the records exhibiting them, with no impact on the full corpus. future directions while proven viable in real-world scenarios, a number of areas which can benefit from further improvements were identified through an analysis of the current implementation, based on the experiences of the five migrations. first, the migration-specific components (connectors and metadata crosswalk, shown in green in figure 1) require further decoupling from the core migration module. for example, since all migrations considered figshare as a target repository, this connector is currently strongly interlinked with the core module, in order to save development time according to business requirements and migration timelines. further decoupling will ensure that the core migration module’s design is not influenced in any way by the repository’s architecture and capabilities. completing this work will also allow making the source code of our current implementation of slam publicly available, as in its current state it is making use of proprietary components which are employed across other parts of the figshare platform. aside from these, the source code includes straightforward python modules and makes use of open technologies such as elasticsearch, which will allow the larger community to adapt and use slam with other source or target repositories, or even enhance it with further functionality. nevertheless, the general architecture can already be implemented in any other way or using a different set of technologies. further to this point, the metadata crosswalk is currently influenced by the logic and design of the migration module; for example, it uses the same procedural programming language, python, as all other components of slam. employing technologies such as extensible stylesheet language transformations (xslt, for metadata in xml formats) or sparql (for rdf) will help involve staff with in-depth domain knowledge further in the migration, for whom these technologies are more familiar; moreover, such a design does not require any knowledge of slam’s internal processes. second, the five completed migrations highlighted the importance of reviewing, correcting, and enhancing records during the migration. for example, when migrating a journal article’s version of record in an open access context, special care needs to be given to its metadata (title, authors, journal name, publication date or persistent identifier), as mistakes can generate issues with scholarly search engines which will not be able to link the published version to the repository one. a possible input for comparing and correcting existing metadata is the information contained by current research information systems, which aggregate information from various databases, such as scopus (https://www.scopus.com/). if access to such systems is not available, it is possible to information technology and libraries december 2021 stateful library analysis and migration system (slam) | pănescu, grosu, and manta 12 source metadata from open directories, such as crossref (https://www.crossref.org/). this component is included in the architectural overview presented in figure 1. the third area in need of improvement relates to testing the outcome of the migrations. as mentioned in the previous section, this is currently a manual process and can be both cumbersome and error prone. while in line with slam’s philosophy of automating every step of the process, implementing a mechanism for validating the end migration result could also provide stronger assurances on the completeness and correctness of the migration. finally, slam’s preservation module requires further development in order to ensure that it is fully automated; moreover, the possibility of adding a manifest explaining the migration artefacts needs to be considered, as knowledge on the organisation of the information, which is specific to each migration, might be lost in time. it is important to note that architecture-wise, which was the main concern of this work, we did not identify any major shortcomings in slam—most issues discussed above focus on implementation issues. slam’s modular design will facilitate any additions to the system, required to support new use cases and migrations. conclusions this paper describes slam, the stateful library analysis and migration system, an etl software architecture for performing digital library migrations. what differentiates such transfers from other data migrations is the required domain knowledge, the particularities of the target and source repositories in the context of the scholarly communications ecosystem, and the structure of the migration package, which includes, among others, bibliographic metadata, record files, and usage data. digital libraries are an integral part of the cultural heritage; thus, any migration needs to ensure that no information is lost or corrupted in the process. the main contributions brought by slam are 1. it includes an analysis module based on an industry standard search engine, elasticsearch, which allows operators to analyse the metadata and schema crosswalk, facilitating the decisions required for properly migrating information between repositories; 2. it implements a serializable state machine in its migration module, which facilitates running the migration procedures multiple times without duplicating, removing, or corrupting records, while allowing for corrections to be applied to the corpus; 3. it follows a modular design, which enhances its reusability across multiple migrations, by reducing the development time required for adapting the system to new source and target repositories. slam applies established software engineering principles in order to provide a trustworthy tool to digital library administrators that need to transfer content between systems. its design was both influenced and validated by real-world applications, having been used for five different migrations with various requirements and targeted repository solutions. future work will consider enhancing slam’s metadata analysis and enrichment capabilities as well as the collection of further data points on its performance and possible improvement directions while using it for new digital library migrations. information

fundamental way in which we understood and evaluated search performance was by measuring precision and recall. in recent decades, however, models of evaluation have expanded to incorporate the information-seeking task and the quality of its outcome, as well as the value of the information to the user. we have developed a systems engineering-based methodology for improving the whole search experience. the approach focuses on understanding users’ information-seeking problems, understanding who has the problems, and applying solutions that address these problems. this information is gathered through ongoing analysis of site-usage reports, satisfaction surveys, help desk reports, and a working relationship with the business owners. ■ evaluation models in the early years of modern information retrieval, the fundamental way in which we understood and evaluated search performance was by measuring precision and recall.1 in recent decades, however, models of evaluation have expanded to incorporate the information-seeking task and the quality of its outcome, cognitive models of information behavior, as well as the value of the information to the user.2 the conceptual framework for holistic evaluation of libraries described by nicholson defines multiple perspectives (internal and external views of the library system as well as internal and external views of its use) from which to measure and evaluate a library system.3 the work described in this paper is consistent with these frameworks as it emphasizes that, while efforts to improve search may focus on optimizing precision or recall, it is equally important to recognize that the search experience involves more than a perfect set of high-precision, high-recall search results. the total search experience and how well the system actually helps the user solve the search task must be evaluated. a search experience begins when users enter words in a search box. it continues when the users view some representation (such as a list or a table) of candidate answers to their queries. it includes the users’ reactions to the usefulness of those answers and their representation in satisfying information needs, and continues with the users clicking on a link (or links) to view content. optimizing search results without considering the rest of the search experience and without considering user behavior is missing an opportunity to further improve user success. for example, the experience is a failure if typical users cannot recognize the answers to their information need because the items lack a recognizable title or an informative description, or they involve extensive scrolling or hard-to-use content. ■ proposed solutions problems with search, such as low precision or low recall, are often addressed by either metadata solutions (adding topical tags to content objects based on controlled vocabularies) or replacement of the search engine. the problems with the metadata approach include the time and effort required to establish, evolve, and maintain taxonomies, and the need for trained intermediaries to apply the tags.4 a community of stakeholders may be convened to define the controlled vocabulary, but often the lowest common denominator prevails, the champions and stakeholders leave, and no one is happy with the resulting standard. even with trained intermediaries, inter-indexer inconsistency compromises this approach, and inconsistent term application can cause degradation of search results.5 another shortcoming of the metadata approach is that a specific metadata classification is just a snapshot in time and assumes that there is only one particular hierarchy of the information in the corpus. in reality, however, there is almost always more than one way to describe a concept, and the taxonomy is the view of only one individual or group of individuals. in addition, topical metadata is often implemented with little understanding of the types of queries that are submitted or the probable user search behavior. the other approach to improving search results— replacing a search engine—is not a guarantee to fixing the problem because it focuses only on improving precision (and perhaps recall as well) without understanding the true barriers to a successful search experience. ■ irs.gov irs.gov, one of the most widely used government web sites, is routinely accessed by millions of people each month (more than 27 million visits in april 2005). as an informational site, the key goal of irs.gov is to direct visitors quickly to useful information, either through marcia d. kerchner (mkerchner@mitre.org) is a principal information systems engineer at the mitre corporation, mclean, va. a dynamic methodology for improving the search experience marcia d. kerchner article title | author 79a dynamic methodology for improving the search experience | kerchner 79 navigation or a search function. given that there were almost 16 million queries submitted to irs.gov in april 2005, search is clearly a popular way for its users to look for information. this paper offers an alternative to conventional search-improvement approaches by presenting a systems engineering-based methodology for improving the whole search experience. this methodology was developed, honed, and modified in conjunction with work performed on the irs.gov web site over a threeyear period. a similar strategy of “sense-and-respond” for information technology (it) departments of public organizations that involves systematic intelligence gathering on potential customer demand, a rapid response to fulfill that demand, and metrics to determine how well the demand was satisfied, has recently been described.6 the methodology described in this paper focuses on analyzing the information-seeking behaviors and needs of users and determining the requirements of the business owners (the irs business operating divisions that provide content to irs.gov, such as small business and self-employed, wage and investment) for directing users to relevant content. it is based on the assumption that a web site must evolve based on its user needs, rather than expecting users to adapt to its singularities. to support this evolution, this approach leverages techniques for query expansion and document-space modification.7 dramatic improvements in quality of service to the user have resulted, enhancing the user experience at the site and reducing the need to contact the help desk. the approach is particularly applicable for those government, corporate, and commercial web sites where there is some control over the content, and usage can be categorized into regular patterns. the rest of this paper provides a case study in the application of the methodology and the application of metrics, in addition to precision and recall, to measure search experience improvement. ■ conceptual framework while analysis of search results often focuses on search syntax and search-engine performance, there are actually several steps in the retrieval process, from the user identifying an information need to the user receiving and reviewing query results. as shown in figure 1, finding information is a holistic process. there are several opportunities to improve the whole user experience by fine-tuning this process with a variety of tools—from document engineering to results categorization. once the user and business-owner needs are understood, the appropriate tools to address specific issues can be identified. the tools in our toolkit are described in the following sections. document engineering document engineering includes: ■ document-space modification: modifying the document space by adding terms to content (especially to titles) that are good discriminators and reflect terms commonly entered by users. this approach has the added benefit of making the content more understandable to users. ■ establishment of content-quality standards: defining business processes that improve content quality and organization. document-space modification there is significant syntactic and semantic impreciseness in the english language. in addition, because of the inadequacies of human or automatic keyword assignment, standard means of representing documents in indexes by statistical term associations and frequency counts or by adding metadata tags are not definitive enough to produce a space that is an exact image of the original documents. document-space modification moves documents in the document space closer to future similar queries by adding new terms or modifying the weight of existing terms in the content (figure 2).8 the document space is thus modified to improve retrieval. for irs.gov, rather than adjusting content weights, titles and content are modified to adjust to changing terminology and user needs. establishment of content-quality standards the quality of the search correlates with the quality of the content. improved search results can be achieved by applying good content-creation practices. retrieval can be significantly improved by addressing problems observed in the content. these problems include inconsistencies in term use—for example, earned income credit (eic) versus earned income tax credit (eitc)—duplicate content, insufficiently descriptive page titles, missing document summaries, misspellings, and inconsistent spellings. figure 1. the information retrieval process 80 information technology and libraries | june 2006 processes to improve content quality should establish standards for consistent term usage in content, as well as standards for consistent and descriptive naming of content types (for example, irs types include forms, instructions, and publications). these processes will not only improve search precision, but will also help users identify appropriate content in the search results. for example, content entitled “publication 503” in response to the query “child care” may be the perfect answer (with excellent precision and recall), but the user will not recognize it as the right answer. a title such as “publication 503: child and dependent care expenses” will clearly point the user to the relevant information. usability tests conducted in march 2005 for irs.gov confirmed that content organization plays an important role in the perceived success of a user’s search experience. long pages of links or scrolling pages of content left some users confused and overwhelmed, unable to find the needed information. for these queries, although the search results were perfect, with a precision of 100 percent after one document, the search experiences were still failures. query enhancement the technique of relevance feedback for query expansion improves retrieval in an iterative fashion.9 according to this approach, the user submits a query, reviews the search results, and then reports query-document relevance assessments to the system. these assessments are used to modify the initial query, that is, new terms are added to the initial query (hopefully) to improve it, and the query is resubmitted. if one visualizes the content in a collection as a space (figure 3), this approach attempts to move the query closer to the most relevant content. a drawback of relevance feedback is that it is not generally collected over multiple user sessions and over time, so the next user submitting the same query has to go through the same process of providing results evaluations for query expansion. borlund has noted that, given that an individual user ’s information need is personal and may change over session time, relevance assessments can only be made by a user at a particular time.10 however, on irs.gov, where there are many common queries for which there is a clear best-guess response, there is valuable relevance information that, if captured once, could benefit tens of thousands of users for specific queries. in fact, in april 2005, the top four hundred queries represented almost half of all the queries. another drawback of the relevance-feedback ap proach is that it forces the user, novice or expert, to become engaged in the search process. as noted previously, users are generally not interested in becoming search experts or in becoming intimately involved in the process of search. the relevance-feedback approach tries to change users’ behavior and forces them to find the specific word or words that will best retrieve the relevant information. in fact, some research has shown that the potential benefits of relevance feedback may be hard to achieve primarily because searchers have difficulty finding useful terms for effective query expansion.11 to avoid requiring users to submit relevance-feedback judgments, the methodology uses alternative approaches for gathering feedback: (1) mining sources of input that do not require any additional involvement on the part of the users; and (2) soliciting relevance judgments from subject matter experts. as noted above, while best results may be different per task and per user, particularly given the shortness of the queries, our goal is to maximize the good results for the maximum number of people. best-guess results are derived from a variety of sources, including usability testing, satisfaction survey questionnaires, and businesscontent owners. for example, users entering the common query “1040ez” can be looking for information on the form or the form itself. given that—as shown in table 1 (based on the responses of 11,715 users to satisfaction surveys in 2005)—the goal of 39 percent of irs.gov searchers is to download a form as opposed to 28 percent seeking to obtain general tax information, the retrieval of the 1040ez form and its instructions is prioritized, while also retrieving any general related information. figure 2. document-space modification figure 3. query modification article title | author 81a dynamic methodology for improving the search experience | kerchner 81 we can determine the best-guess results as follows: ■ review the search results for terms that are on the frequently entered search-terms list ■ review help desk contacts, satisfaction-survey comments, and zero-results reports to identify information users who are having trouble finding or understanding ■ identify best results by working with the business owners as necessary ■ analyze why best results are not being retrieved for a particular query ■ add appropriate synonyms for this and related queries ■ engineer relevant documents (as described above) in this way, the thesaurus, as the source for query enhancement, is an evolving structure that adapts to the needs of the users rather than being a fixed entity of elements based on someone’s idea of a standardized vocabulary. search improvement we can intercept very popular queries and return a set of preconfigured results or a quick link at the top of the search-results listing. for example, the user entering “1040” sees a list of the most popular 1040-related forms and instructions in addition to a list of other search results. there were more than 31,000 users in april 2005 who requested the i-9 form. since the form is not an irs form, users are presented with a link to the bureau of citizen and immigration services web site. the tens of thousands of users who look for state tax forms on irs.gov are directed either to the specific state-tax-form website page or to a page with links to state tax sites. this unique and user-friendly approach provides a significant improvement over a page that tells the user that there is no matching result, leaving him to fend for himself. another technique for improving search precision (not currently used for irs.gov) is to tune and adjust parameters in the search engine, such as the relative weighting of basic metadata tags such as title (if they are used in the relevance calculation). results-ranking improvement the search results can be programmatically re-ranked before being presented to the user. this approach (not used as yet on irs.gov) is a variation on the quick links described above for re-ranking more than one result. categorization a large set of search results can be automatically categorized into subsets to help the user find the information he needs. in addition, a “search within a search” function is available to help the user narrow down results. research to be conducted on commercial products to support automatic categorization is planned for the future. summarization as noted earlier, a barrier to a successful user experience can be the lack of informative descriptions in the search results. therefore, an important tool for search-experience improvement is to make sure that content titles and summaries are informative, or as a second choice, that the search engine dynamically generates informative summaries. passage-based summaries and highlighted search terms in the summary and the content have become a feature of many commercial search engines as another way to improve the usability of the returned results. in table 1. reasons for

from a different metadata field was added to the search display programmatically, which improved the usability of such results significantly. ■ methodology the methodology for evolving the search functionality is based on a logical, systems-engineering approach to the issue of getting users the information they seek: understanding the problems, understanding who has the problems, and applying solutions that address the problems. usability studies, weblogs, focus groups, help desk contacts, and user surveys provide different perspectives of the information system. the steps of the methodology are: 1. understand the user population. 2. identify the barriers to a successful search experience. 3. analyze the information-seeking behaviors of the users. 4. understand the needs of the business owners. 5. identify and use the appropriate tools to improve the user’s search experience. 6. repeat as needed. 7. monitor new developments in search and analytic technologies and replace the search engine as appropriate. step 1: understand the user population the first step is to profile and understand the user population. as mentioned above, an online satisfaction survey was conducted during a six-week period in january– february 2005, to which 11,715 users responded. the users were asked the frequency of their usage of the site, their primary reason for coming to irs.gov, their category (individual, tax professional, business representative), and how they generally find information on irs.gov. as shown in tables 1–4, 76 percent of the irs. gov visitors use it once a month or less (the largest group being those who use it every six months or less), or were using it for the first time; 64 percent are individual taxpayers; 10 percent are tax professionals; 39 percent visit the site to download a form or publication; and 27 percent come for general tax or e-file information. forty-nine percent use the search engine. not surprisingly, 44 percent of the frequent visitors (those who visit once a week or more) are tax professionals, while 72 percent of the infrequent visitors are individuals or those who represent a business. the most common task of both the most frequent and infrequent visitors is to download a form, publication, or instructions, followed by obtaining general tax information. most frequent and infrequent visitors use the search function to locate their information. thus, the largest group of irs.gov users consists of average citizens, unfamiliar with the site, who have a specific question or a need for a specific form or publication. these users require high-precision, highly relevant results, and a highly intuitive search interface. they do not want or need to read all the material generated by their search, but they want their question answered quickly. these users are generally not experienced with sophisticated query language syntax, and because they come to the site no more than once a month, they are not likely to be familiar with its navigational organization. as studies demonstrate, users in general do not want to learn a search engine interface or tailor their queries to the design of a particular search engine.12 they want to find their information now before “search rage” sets in. one study observed that, on average, searchers get frustrated in twelve minutes.13 tax professionals form a small but important group of irs.gov users that includes lawyers, accountants, and tax preparers. they generally use the site on a regular basis, which could be daily, weekly, or monthly. some of these users, particularly lawyers and accountants, require high relevance in their search results; it is critical that they retrieve every relevant piece of information (e.g., all the tax regulations) related to a tax topic. they may be willing to sift through large results sets to make sure they have seen all the relevant items. in contrast, many tax preparers use the site primarily to download forms and instructions. while these different sets of users have different levels of expertise using the site and somewhat different precision and recall requirements, they do have one characteristic in common—they are not interested in search table 2. frequency of visits to irs.gov first time every six months or less about once a month about once a week daily more than once a day site visitor 29%

results that focus on forcing users to use tools to refine their query to get presumably better search results (e.g., leveraging the power of boolean or other search syntax) are not desirable in a public web site environment. the complexity of the search must be hidden behind the search box and users must be helped to find information rather than be expected to master a search function. step 2: identify the barriers to a successful search experience there are several categories of reasons why finding information on a public web site can be frustrating for the user. ■ mismatch between user terminology and content terminology  the user search terms may not match the terminology or jargon used in the content (e.g., users ask for “tax tables” or “tax brackets”; the irs names them “tax rate schedules”).  multiple synonymous terms or acronyms are found because different authors are providing content on similar topics (e.g., “ein,” “employer identification number,” “federal id number”; “eic” versus “eitc”).  users request the same information in a variety of ways (e.g., “1040ez,” “1040-ez,” “ez,” “form1040ez,” “1040ez form,” “2005 1040ez,” “ez1040”).  related content may be inconsistently named, complicating the user’s search process (e.g., “1040x” form versus “1040-x” instructions).  the user may use a familiar acronym that is spelled out in the content (e.g., “poa” for “power of attorney”). ■ mismatch between user requests and actual content  many users ask for information that they expect to find on the site but is actually hosted at another site (e.g., “ds156,” a department of state form; “it-201,” a new york state tax form). ■ issues with results listing and content display  content may lack informative titles.  automatically generated summaries may not be sufficiently descriptive for users to recognize the relevant material in the results listing.  content may consist of long, scrolling pages, which users find hard to manage. ■ incomplete user queries  very short search phrases (average length of less than two words) can make it difficult for a search algorithm to deduce the specific content the user is seeking. step 3: analyze the information-seeking behaviors of the users site-usage reports, satisfaction surveys, help desk contact reports, zero-results reports, focus groups, and usability studies are valuable sources of information. they should be mined for information-seeking behaviors of the site’s users and other barriers to a successful search experience, as follows: ■ review site-usage reports for the most frequently entered search terms and popular pages (both may change over time) and the zero-results search terms. look for:  new terms  variations on popular terms  common misspellings or typos  common searches, including searches for items table 3. irs.gov user types type of user % of total site visitors % of total search users individual taxpayer 64% 64% representing a business 11% 11% tax

as with content findability and usability ■ review help desk contact reports  identify which topics users are having trouble finding or understanding step 4: understand the needs of the business owners the business owners are the irs business operating divisions that provide content to irs.gov, such as small business and self-employed, wage and investment. it is important to involve them in the process of enhancing the user experience, because they may have specific goals for prioritizing information on a particular topic or may be managing campaigns for highlighting new information. thus it is desirable to: ■ meet with business owners regularly to understand their goals for providing information to users ■ work with them to increase the findability of their content for example, when an issue in finding a particular content topic is identified (e.g., through an increase in help desk contacts), one approach is to show the business owner the actual results that common queries (based on the site-usage reports) on the topic retrieve and then present suggested alternative results that could be retrieved with a variety of enhancement techniques, such as thesaurus expansion or title improvement. the business owner can then evaluate which set of results presents the content in the most informative manner to the user. steps 1–4 facilitate work behind the scenes to gather the data needed to improve precision and recall and to make information more findable. the remaining steps use these data to adapt proven, widely used techniques for improving search experiences to a web site’s specific environment. step 5: identify appropriate tools to improve the information-retrieval process as described in the previous section, the tools in our toolkit are document engineering, query enhancement, search improvement, results-ranking improvement, categorization, and summarization. step 6: repeat as needed the process of improving the user search experience is ongoing as the site evolves. at irs.gov, different search terms appear on the site-usage reports over time, depending on whether or not it is filing season, or as new content and applications are published. human intervention (with the help of applicable tracking software) is essential for incorporating business requirements, evaluating human behavior, and identifying changing terms. step 7: monitor new developments in search and analytic technologies and replace the search engine as appropriate although a new search engine will not address all the issues that have been described, new features such as passage-based summaries and term-highlighting can improve the search experience. of course, one should consider replacing a search engine if new technology can demonstrate significantly improved precision and recall. the application of the methodology and the use of the toolkit for irs.gov will be described in the next section. ■ findings site-usage reports in 2003, an example of a serious mismatch in user and content terminology was discovered when site-usage reports were analyzed. users entering the equivalent terms ein, employer number, employer id number, and employer identification number retrieved significantly different sets of results. we met with the business owner, who identified a key-starting page that should be retrieved along with other highly relevant pages for all of these query terms. we recommended that “ein” be added to the title of the key page because, although ein is a very popular query, the acronym was not used in the content, but was instead spelled out. as a result, the key page was not being retrieved. synonyms were added to the query enhancement thesaurus to accommodate the variants on the ein concept. after these steps were implemented, the results were as follows: ■ for the query ein, the target page moved from #16 to #1 ■ for the query ein number, it moved from #17 to #5 article title | author 85a dynamic methodology for improving the search experience | kerchner 85 ■ for the query employer identification number, it moved up to #2 (it was not in the top 20 previously) ■ all search results now retrieved on the first page for these terms were highly relevant in january 2004, there were approximately twenty thousand queries using these terms, so the search experience has been improved for tens of thousands of users in one month and hundreds of thousands of users throughout the year. ■ review of help desk contacts help desk reports summarize, for each call or e-mail, the general topic of the user’s contact (filing information, employer id number, forms, and publications issues) and the specific question. for example, the report might indicate that a user needed help in finding or downloading the w-4 form or did not understand the instructions for amending a tax return. as help desk contact reports were reviewed, clusters of questions emerged indicating information that many users could not find or understand. by analyzing approximately 9,800 contacts (e-mail, telephone, chat) during a peak five-day period in april 2003, four particular areas were identified that were ripe for improvement: 480 users could not find previous years’ forms, which, although they can be found on the site, are not indexed and thus not findable through search; 250 users had questions about where to send their tax returns; 170 users had questions about getting a copy of their tax return or w-2 form; and 77 users had problems finding the 1040x or 1040ez forms. utilizing the information retrieval toolkit, the following improvements were implemented: a) search for previous years’ forms tool used: results-ranking improvement a user requesting a previous year’s forms (for example, 2002 1099misc) is now presented with a link directly to the page of forms for that specific year, as follows: recommendation(s) for: 2002 1099misc ■ 2002 forms and publications 2002 forms, instructions, and publications available in pdf format b) request for filing address tools used: document engineering and query enhancement a new “where to file” page was created. synonyms were added to the thesaurus to accommodate the variations on how people make this request (address, where to send, where to mail) and to prioritize retrieval of the “where to file” page. c) request for information about obtaining a copy of a tax return or w-2 form tools used: results-ranking improvement and query enhancement a “quick link” was created to the target page for getting a copy of returns and w-2 forms and synonyms were added to the thesaurus to prioritize related content for any query containing the word “copy.” d) requests for 1040x or 1040ez forms or instructions tool used: query enhancement synonyms were added to the thesaurus to address both the variations on how users requested the 1040x and 1040ez forms and instructions, and the inconsistencies in the titling of these documents (for example, the form and the instructions have different variations of the compound name). ■ results in 2004, approximately 4,200 contacts were reviewed with the help desk during the same time period (the week before april 15) to see whether the changes actually did help users find the information. it should be noted that, during this period from april 2003 to april 2004, many other improvements to the user search experience based on the methodology were deployed. although the number of visits to irs.gov increased by approximately 50 percent compared with the same period in 2003, the total number of contacts with the help desk decreased by 47 percent (there were approximately 9,800 contacts in this period in 2003). the results for the specific improvements are shown in table 5. the average decrease in contacts for those four topics was 68 percent, compared with the average decrease of 47 percent. this approach has significantly improved the user experience by identifying and addressing subject areas users have trouble finding or understanding on irs.gov, eliminating the need for them to contact the help desk. as a result, an increase of resources at the help desk was avoided and, hopefully, user satisfaction improved. 86 information technology and libraries | june 2006 ■ conclusions while the case presented in this article was specific to irs.gov, the methodology itself has wide application across domains. customer service for most government and commercial organizations depends on providing users with relevant information effectively and efficiently. there are many aspects to achieving this elusive goal of matching users with the specific information they need. in this paper, it has been demonstrated that, rather than focusing just on optimizing the search engine or developing a metadata-based solution, it is essential to view the user search experience from the time content is created to the moment when users have truly found the answer to their information needs. there is no one surefire solution, and one should not assume that enhanced metadata or a new search engine is the only solution to retrieval problems. the methodology described in this paper assumes that users, especially infrequent users of public web sites, do not wish to become search experts; that intuitive interfaces and meaningful results displays contribute to a successful user experience; and that keeping business owners involved is important. the methodology is based on understanding the behavior of a site’s users in order to identify barriers to a successful search experience, and on understanding the needs of business owners. the methodology focuses on adapting the site to its users (rather than vice versa) through document modification, improved content-development processes, query enhancement, and targeted search improvement. it includes improvements to the results phase of the search process, such as improved titles and summaries, as well as to the searchand-retrieval phase. this toolkit-based approach is effective and low-cost. it has been used over the past four years to improve the user search experience significantly for the millions of irs.gov users. interesting follow-on research could focus on identifying to what degree this methodology can be automated and how to leverage new tools to provide automated support for usage log analysis (such as mondosearch by mondosoft). it is clear from this case study that it is time to apply systems engineering rigor to search-experience improvement. this approach confirms the need to extend metrics for evaluating search beyond precision and recall to include the totality of the search experience. ■ future work teleporting has been defined as an approach in which users try to jump directly to their information targets.14 trying to achieve perfect search results supports the information-seeking strategy of teleporting. but the search process may involve more than a single search. people often conduct “a series of interconnected but diverse searches on a single, problem-based theme, rather than one extended search session per task.”15 this approach is similar to the sport of orienteering with searchers using data from their present situation to determine where to go next—that is, looking for an overview first and then submitting more detailed searches. given the general, nonspecific nature of the short queries submitted by irs.gov users, the orienteering approach may well describe the information-seeking behaviors of many users. this paper is limited to the improvement of search results for individual searches, but the need to investigate improving the search experience to support orienteering behavior is acknowledged. future research will investigate how to leverage the theoretical models of the information-search process, such as the anomalous states of knowledge (ask) underlying information needs and the information search process model.16 references and notes 1.

technology and libraries | june 2008 communications michaela brenner and peter klein discovering the library with google earth libraries need to provide attractive and exciting discovery tools to draw patrons to the valuable resources in their catalogs. the authors conducted a pilot project to explore the free version of google earth as such a discover tool for portland state library’s digital collection of urban planning documents. they created eye-catching placemarks with links to parts of this collection, as well as to other pertinent materials like books, images, and historical background information. the detailed how-to-do part of this article is preceded by a discussion about discovery of library materials and followed by possible applications of this google earth project. in calhoun’s report to the library of congress, it becomes clear that staff time and resources will need to move from cataloging traditional formats, like books, to cataloging unique primary sources, and then providing access to these sources from many different angles. “organize, digitize, expose unique special collections” (calhoun 2006). in 2005, portland state university library received a grant “to develop a digital library under the sponsorship of the portland state university library to serve as a central repository of the collection, accession, and dissemination of [urban] key planning documents . . . that have high value for oregon citizens and for scholars around the world” (abbott 2005). this collection is called the oregon sustainable community digital library (oscdl) and is an ongoing project that includes literature, planning reports, maps, images, rlis (regional land information system) geographical data, and more. much of the older material is unpublished, and making it available online presents a valuable resource. most of the digitized—and, more recently, borndigital—documents are accessible through the library’s catalog, where patrons can find them together with other library materials about the city of portland. the bibliographic records are arranged in the catalog in an electronic resource management (erm) system (brenner, larsen, and weston 2006). additionally, these bibliographic data are regularly exported from the library catalog to the oscdl web site (http://oscdl. research.pdx.edu) and there integrated with gis (global information system) features, thus optimizing cataloging costs by reusing data in a different electronic environment. committed to not falling into the trap that clifford lynch had in mind when he wrote, “i think there is a mental picture that many of us have that digitization is something you do and you finish . . . a finite, one-time process“ (lynch 2002), and agreeing with gatenby that “it doesn’t matter at all if a user finds our opac through the ‘back door ’“ (gatenby 2007), the authors looked into further using these existing data from the library catalog by making them accessible from a popular and appealing place on the internet, a place that users are more likely to visit than the library catalog. the free version of google earth, a virtual-globe program that can be installed on pcs, lent itself to experimenting. “google earth combines the power of google search with satellite imagery, maps, terrain and 3-d buildings to put the world’s geographic information at your fingertips” (http://earth.google.com). from there, the authors provide links to the digitized documents in the library catalog. easy distribution, as well as the more playful nature of this pilot project and the inclusion of pictures, make the available data even more attractive to users. “google now reigns” “google now reigns,” claims karen markey (markey 2007), and many others agree that using google is easier and more appealing to most than using library catalogs. google’s popularity has been growing spectacularly. in august 2007, google accounted for 64 percent of all u.s. searches (avtec media group 2007). in contrast, the oclc report on how users perceive the library shows that only one percent of the respondents begin their information search on a library web site, while 84 percent use search engines (de rosa, et al. 2005). “if we [libraries] want to survive,” says stephen abram, “we must place our messages where the users are seeking answers and will trip over them. today that usually means at yahoo, msn, and google” (abram 2005). according to lorcan dempsey, in the longer run, traffic to the library catalog will come by linking from larger consolidated resources, like open worldcat and google scholar (dempsey 2005). dempsey also stressed that it becomes more and more significant to differentiate between discovery and location (dempsey 2006a). initially, users want to discover; they want to find what interests them independent from where this information is actually located and available. while there may be lots of valuable, detailed, and exceptionally well-organized bibliographic information in the library catalog, not michaela brenner (brennerm@pdx.edu) is assistant professor and database maintenance and catalog librarian at portland state university library, oregon. peter klein (peter.klein@colorado.edu) is aerospace engineering bs/ms at the university of colorado at boulder. introducing zoomify image | smith 33discovering the library with google earth | brenner and klein 33 many users (one percent) are willing to discover this information through the catalog. they may not discover what a library has to offer if “the library does not find a way to go to the user, rather than waiting for the user to come to the library” (coyle 2007). unless the intent is to keep our treasures buried, the library community needs to work with popular outside discovery environments— like search engines—to bring information available in libraries to users from the outside. libraries are, although sometimes reluctantly, responding. google, google scholar, and google books are open worldcat partner sites that are now or soon will be providing access to worldcat records. google book search includes “find this book in the library,” and the advanced book search also has the option to limit a search to library catalogs with access to the worldcat web record for each item. “deep linking” enables web users to link from search results in yahoo, google, or other partner sites to the “find in a library” interface in open worldcat, and then directly to the item’s record in their library’s online public access catalog (opac). simply put, “find it on google, get it from your library” (calhoun 2006). the “leveraged discovery environment” is an expression coined by dempsey that means it becomes increasingly important to leverage a “discovery environment which is outside your control to bring people back into our catalog environment (like amazon, google scholar)” (dempsey 2006b). issues in calhoun’s report to the library of congress include the question of how to get a google user from google to library collections. she quotes an interviewee saying that “data about a library’s collection needs to be on google and other popular sites as well as the library interface” (calhoun 2006). with evidence pointing to the heavy use of google for discovery and with google earth technology providing such a powerful visualization tool, the authors felt tempted to experiment with existing data from portland state library’s digital oscdl collection and make these data accessible through a virtual globe. the king’s college cultural heritage project martyn jessop from king’s college in london, united kingdom, published an article about a relatively small pilot project on providing access to a digital cultural heritage collection through a geographical information system (jessop 2005). jessop’s approach to explore different technologies and techniques to apply to existing data about unique primary sources was exactly what the authors had in mind with this project, and provided encouragement to move forward with the idea of providing additional access to the oregon sustainable community digital library (oscdl) collections through google earth. similar to jessop, the authors regard it an unaffordable luxury to put a great deal of effort into collecting, digitizing, and cataloging materials without making them available to a much broader audience through multiple access points. comparable to jessop, the goal of this project was to find a relatively simple, low-cost technological solution that could also be applied to a much wider range of data without much more investment in staff time and money. once the authors mastered the initial hurdle of understanding google earth’s programming language, they could easily identify with jessop’s notion of “project creep” as more and more possibilities arose to make the project more appealing. this, as with the king’s college project, was a valuable part of the development process, the details of which are described below. the portland state library oscdl-ongoogle-earth project the authors chose ten portlandbased oscdl sub-collections as the basis of this pilot project: harbor drive, front street, portland public market, urban studies collection, downtown, park blocks, south park blocks, pioneer courthouse square, portland city archives, and jpact (joint policy advisory committee on transportation). the programming language for google earth is kml (keyhole markup language), a file format used to display geographic data. kml is based on the xml standard and can be created with the google earth user interface or from scratch with a simple text editor. having no previous kml experience, the authors decided to use both. figure 1. basic placemark in google earth figure 2. kml script for basic placemark 34 information technology and libraries | june 200834 information technology and libraries | june 2008 a basic placemark provided by google earth (figure 1), copied and pasted in notepad (figure 2), was the starting point. at portland state library, information technology routinely batch export cataloged oscdl data from the library catalog (ils) to the oscdl web site to reuse them. for the google earth project, the authors had two options, to either export data relevant to our collections from the ils to a spreadsheet or to use an existing excel spreadsheet containing most of the same data, including place coordinates. this spreadsheet was one of many others that had been created to keep track for the digitization process as well as for creating bibliographic records for the library catalog later. using the available spreadsheet again, the following data were retained: n the title of the collection n longitude and latitude of the place the collection refers to n a brief description of the collection the following were added manually to the remaining spreadsheet: n all the texts and urls for the collection-specific links n urls for the collection-specific images the authors extracted the placemark-specific script from figure 2 to create a template in notepad. a general description and all links that were the same for the ten collections were added to this template, and placeholders were inserted for collection-specific data (figure 3). using microsoft office word’s mail merge, the authors populated the template with the data from the spreadsheet in one quick step. the result was a kml script that included all the placemark data for the ten collections (figure 4). the script was saved as plain text (.txt) first, and then renamed with the extension .kml, which represents the final file (figure 5). clicking the oscdl.kml icon on a desktop or inside a web application opens google earth. the user “flies” to portland, where ten stars represent the ten collections (figure 6). zooming in, the placemarks show the locations to which the collections refer. considering the many layers and icons available in google earth, the authors decided to use yellow stars to make them more visible. in order to avoid clutter and overlapping labels, titles only appear on mouse-over (figures 7 and 8). figure 9 shows the open placemark for portland public market. “portland state university” with the university’s logo is a link that takes the user to the university’s homepage. the next line is the title of the collection, followed by a brief description. the paragraph after that is the same for all collections and includes links to the portland state university library and the oscdl web site. the collection-specific links that follow next go to the library catalog where the user has access to the digitized manuscripts of this collection (figure 10). other pertinent links—in this case to a book available in the library, a public web site on the history of the market, and a historic image of the market—were added as well. to make the placemarks visually more attractive, all links are presented in the school’s “psu green,” and an image representative of the collection was added. the pictures can be enlarged in a new window by clicking on them. to avoid copyright issues, the authors photographed their own images. the last link opens an e-mail window for questions and comments (figure 11). this link is intended to bring some feedback and suggestions on how to improve the project and on its value for researchers and other users. the authors have been toying with the idea of including in the future more elaborate features such as video clips and music. one more recent feature is that kml files, created in google earth, can now also be viewed on the web by simply entering the url of the kml file into the search box of google maps (figure 12), thus creating google earth placemarks in figure 3. detail of template with variables between « double brackets » figure 4. detail: “downtown” placemark of finished kml script figure 5. simplified process

(figures 13 and 14). not all formatting is correctly transferred, and at this point, there is no way to correct this in google maps. for example, the yellow stars were white, the mouse-over didn’t work and the size of the placemarks was imprecise. however, the content of the placemarks—except for the images which didn’t show on some computers—was fully retained and all links worked (figure 15). although the use of the kml file in google maps is not as elegant as in google earth, it has the advantage that there is no need to install software as with google earth. this adds value to kml files and makes projects like this more versatile. the authors have identified several uses for the kml file: n a workstation in the library can be dedicated to resources about the city of portland. an icon on the desktop of this workstation will open google earth and “fly” directly to portland where the yellow stars are displayed. n professors can easily add the .kml file to webct (now blackboard) or other course management systems. n the file can be e-mailed as an figure 7. zoomed in with mouse-over placemark figure 8. location of the pioneer courthouse square placemark figure 9. portland public

added to the google earth gallery where many remarkable projects, created by individuals and groups can be found. n it can also be accessed through the oscdl web site, and relevant links from the records in the library catalog to google maps can be included. it may be useful to alert patrons, who actually did come to the catalog by themselves, to this visual tool. conclusion “the question now is not how we improve the catalog as such,” says dempsey. “it is how we provide effective discovery and delivery of library materials in a network environment where attention is scarce and information resources are abundant and where discovery opportunities are being centralized into major search engines and distributed to other environments” (dempsey 2006a). with this in mind, the authors took on the challenge to create another discovery tool for one of the library’s primary unique digital collections. google earth is not the web, and it needs to be installed on a workstation in order to use a kml file. on the other hand, the file created in google earth can also be used on the web more readily but less elegantly in google maps, thus possibly reaching a larger audience. similar to the king’s college project and following abram’s suggestion that “we should experiment more with pilots in specific areas” (abram 2005), this pilot project is of an exploratory, experimental nature. and as with many experiments, the authors were testing an idea, trying something different and new to find out how useful this idea might be, and useful applications for this project were identified. google earth is a sophisticated, attractive, and exciting program—and fun to play with. in a time “where attention is scarce and information resources are abundant,” as dempsey (2006a) says, we need to provide these kinds of discovery tools to attract patrons and to lure them to these valuable resources in our library’s catalog that we created with so much diligence and cost of staff time and resources. works cited abbott, carl. 2005. planning a sustainable portland: a digital library for local, regional, and state planning and policy documents. framing paper.

online social networks has gained much attention from the media, few studies in library science have yet to address the topic in depth. this article reports on a survey of 126 academic librarians concerning their perspectives toward facebook.com, an online network for students. findings suggest that librarians are overwhelmingly aware of the “facebook phenomenon.” those who are most enthusiastic about the potential of online social networking suggested ideas for using facebook to promote library services and events. few individuals reported problems or distractions as a result of patrons accessing facebook in the library. when problems have arisen, strict regulation of access to the site seems unfavorable. while some librarians were excited about the possibilities of facebook, the majority surveyed appeared to consider facebook outside the purview of professional librarianship. d uring the fall of 2005, librarians noticed something unusual going on in the houston cole library (hcl) at jacksonville state university (jsu). students were coming into the library in droves. patrons waited in lines with photos to use the public­access scan­ ner (a stack of discarded pictures quickly grew). library traffic was noticeably busier than usual and the computer lab was constantly full, as were the public­access termi­ nals. the hubbub seemed to center around one particular web site. once students found available computers, they were likely to stay glued to them for long stretches of time, mesmerized and lost in what was later determined to be none other than “facebook addiction.” this addic­ tion was all the more obvious the day the internet was down. withdrawal was severe. soon after the librarians noticed this curious behavior, an article in the chanticleer, the campus newspaper for jsu, dispelled the mystery surrounding the web­site brouhaha. a campus reporter broke the exciting news to the jsu community that “after months of waiting and requests from across the country, it’s finally here. jsu is officially on the facebook.”1 the library suddenly became a popular hangout for students in search of computers to access facebook. apparently jsu jumped on the bandwagon relatively late. the facebook craze had already spread throughout other colleges and universities since the web site was founded in february 2004 by mark zuckerberg, a former student at harvard university. the creators of facebook vaguely define the site as “a social utility that connects you with the people around you.”2 although originally created to allow students to search for other students at colleges and universities, the site has expanded to allow individuals to connect in high schools, companies, and within regions. recently, zuckerberg has also announced plans to expand the network to military bases.3 currently, students and alumni in more than 2,200 colleges and uni­ versities communicate, connect with other students, and catch up with past high school classmates daily through the network. students who may never physically meet on campus (a rather serendipitous occurrence in nature) have the opportunity to connect through facebook. establishing virtual identities by creating profiles on the site, students post photographs, descriptions of academic and personal interests such as academic majors, campus organizations of which they are members, political orientation, favorite authors and musicians, and any other information they wish to share about themselves. facebook’s search engine allows users to search for students, faculty, and staff with similar interests by keyword. it would be hard to gauge how many of these students actually meet in person after connecting through facebook. the authors of this study have heard students mention that either they or their friends have made dates with other students on campus through facebook. many of the “friends” facebook users first add when they initially establish their accounts are the ones they are already acquainted with in the physical world. when facebook made its debut at jsu, it had become the “ninth most highly trafficked web site in the u.s.”4 one source estimated that 85 percent of college students whose institutions are registered in facebook’s directory have created personal profiles on the site.5 membership for the university network requires a university e­mail address, and an institution cannot be registered in the directory unless a significant number of students request that the school be added. currently, more than nine mil­ lion people are registered on facebook.6 soon after jsu was registered on facebook’s direc­ tory, librarians began to receive questions regarding use of the scanner and requests for help uploading pictures to facebook profiles. students seemed surprisingly open about showing librarians their profiles, which usually contained more information than the librarians wanted to know. however, not all students were enthusiastic about facebook. complaints began to surface from students awaiting access to computers for academic work while classmates “tied up” computers on facebook. some stu­ dents

currently, the administra­ tion at jsu has decided to block access to facebook in the computer labs on campus, including the lab in the library. opinions of faculty and staff in the library about facebook vary. some librarians scoff at this new trend, viewing the site primarily as just another dating service. others have created their own facebook accounts just to see how it works, to connect with students, and to keep up with the latest internet fad.7 ■ study rationale prompted by the issues that have arisen at hcl as a result of heavy patron use of facebook, the authors surveyed academic librarians throughout the united states to find out what impact, if any, the site has had on other libraries. the authors sought information about the practical effect facebook has had on libraries, as well as librarians’ perspectives, perceived roles associated with, and awareness of internet social trends and their place in the library. online social networking, like e­mail and instant messaging, is emerging as a new method of com­ munication. recently, the librarians have heard facebook being used as a verb (e.g., “i’ll facebook you”). few would probably disagree that making social connections and friends (and facebook revolves around connecting friends) is an important aspect of the campus experi­ ence. much of the attraction students and alumni have toward college yearbooks (housed in the library) stems from the same fascination that viewing photos, student profiles, and searching for past and present classmates on facebook inspires. emphasis in this study centers on librarians’ awareness of, experimentation with, and atti­ tudes towards facebook and whether or not they have created policies to regulate or block access to the site on public­access computers. however trendy an individual web site such as facebook may appear, online social networking, a cat­ egory facebook falls within, has become a new subject of inquiry to marketing professionals, sociologists, commu­ nication scholars, and library and information scientists. downes defines social networks as a “collection of indi­ viduals linked together by a set of relations.”8 according to downes, “social networking web sites fostering the development of explicit ties between individuals as ‘friends’ began to appear in 2002.”9 facebook is just one of many popular online social network sites (myspace, friendster, flickr), and survey respondents often asked why questions focused solely on facebook. the authors decided to investigate it specifically because it is cur­ rently the largest online social network targeted for the academic environment. librarians are also increasingly exploring the use of what have loosely been referred to as “internet 2.0” com­ panies and services, such as facebook, to interact with and reach out to our users in new and creative ways. the term internet 2.0 was coined by o’reilly media to refer to internet services such as blogs, wikis, online social net­ working sites, and types of networks that allow users the ability to interact and provide feedback. o’reilly lists the core competencies that define internet 2.0 services. one of these competencies, which might be of particular inter­ est to librarians, is that internet 2.0 services must “trust the users” as “co­developers.”10 as librarians struggle to develop innovative ways to reach users beyond library walls, it seems logical to observe online services, such as facebook and myspace, which appeal to a huge portion of our clientele. from a purely evaluative standpoint of the site as a database, the authors were impressed by several of the search features offered in facebook. graph­theory algo­ rithms and other advanced network technology are used to process connections.11 some of the more interesting search options available in facebook include the ability to: ■ search for students by course field, class number, or section; ■ search for students in a particular major; ■ search for students in a particular student organiza­ tion or club; ■ create “groups” for student organizations, clubs, or other students with common interests; ■ post announcements about campus or organization events; ■ search specifically for alumni; and ■ block or limit who may view profiles, providing users with built­in privacy protection if the user so wishes. since the authors finished the study, the site has added a news feed and a mini feed, features that allow users to keep track of their friends’ notes, messages, profile changes, friend connections, and group events. in response to negative feedback about the news feeds and mini feeds by users who felt their privacy was being violated, facebook’s administrators created a way for users to turn off or limit information displayed in the feeds. the addition of this technology, however, provides a sophisticated level of connectivity that is a benefit to users who like to keep abreast of the latest happenings in their network of friends and groups. the pulse, another feature on the site, keeps daily track of popular interests (e.g., favorite books) and member demographics (number of members, political orientation) and compares them with overall facebook member averages. the authors were pleasantly surprised to discover that the beatles and led zeppelin, beloved bands of the baby boomers, article title | author 25checking out facebook.com | charnigo and barnett-ellis 25 continue to live on in the hearts of today’s students. these groups were ranked in the top ten favorite bands by stu­ dents at jsu. as of october 2006, the top campaign issues expressed by facebook users were: reducing the drinking age to eighteen (go figure) and legalization for same­sex marriage. arguably, much of the information provided by facebook is not academic in nature. however, an evaluation or review of facebook might provide useful information to instruction librarians and database ven­ dors regarding interface design and search capabilities that appeal to students. provitera­mcglynn suggests that facilitating learning among millennials, who “represent 70 to 80 million people” born after 1992 (a large percent­ age of facebook members) involves understanding how they interact and communicate.12 awareness of students’ cultural and social interests, and how they interact online, may help older generations of academic librarians better connect with their constituents. ■ the literature on online social networks although social networks have been the subject of study by sociologists for years and social network theories have been established to describe how these networks func­ tion, the study of online social networks has received little attention from the scholarly community. in 1997, garton, haythornthwaite, and wellman were among the first to describe a method, social network analysis, for studying online social networks.13 their work was published years before online social networks similar to facebook evolved. currently, the literature on these networks is predominantly limited to popular news pub­ lications, business magazines, occasional blurbs in library science and communications journals, and numerous student newspapers.14 privacy issues and concerns about sexual predators lurking on facebook and similar sites have been the focus of most articles. in the chronicle of higher education, read details numerous arrests, suspensions, and schol­ arship withdrawals that have resulted from police and administrators searching for incriminating information students have posted in facebook.15 read discovered that, because students naively reveal so much informa­ tion about their activities, some campus police were regularly trolling facebook, finding it “an invaluable ally in protecting their campuses.”16 students may feel a false sense of security when they post to facebook, regarding it as their private space. however, read warns that “as more and more colleges offer alumni e­mail accounts, and as campus administrators demonstrate more internet savvy, students are finding that their conversations are playing to a wider audience than they may have antici­ pated.”17 privacy concerns expressed about facebook appear to revolve more around surveillance than stalk­ ers. in a web seminar on issues regarding facebook use in higher education, shawn mcguirk, director of judicial affairs, mediation, and education at fitchburg state college, massachusetts, recommends that administrators and others concerned with students posting potentially incriminating, embarrassing, or overtly personal infor­ mation draft a document similar to the one created by cornell university’s office of information technologies, which advises students on how to safely and responsibly use online social networking sites similar to facebook.18 after pointing out the positive benefits of facebook and reassuring students that cornell university is proud of its liberal policy in not monitoring online social networks, the essay, entitled “thoughts on facebook,” provides poignant advice and examples of privacy issues revolv­ ing around facebook and similar web sites.19 the golden rule of this essay states: don’t say anything about someone else that you would not want said about yourself. and be gentle with your­ self too! what might seem fun or spontaneous at 18, given caching technologies, might prove to be a liability to an on­going sense of your identity over the longer course of history.20 a serious concern discussed in this document is the real possibility that potential employers may scan facebook profiles for the “real skinny” on job candidates. however, unless the employer uses an e­mail issued from the same school as the candidate, he or she is unable to look at the individual’s full profile without first request­ ing permission from the candidate to be added as a “friend.” all the employer is able to view is the user’s name, school affiliation, and picture (if the user has posted one). unless the user has posted an inappropriate picture or is applying for a job at the college he or she is attending, the threat of employers snooping for informa­ tion on potential candidates in facebook is minimal. the same, however, cannot be said of myspace, which is much more open and accessible to the public. additionally, three pilot research studies have also focused on privacy issues specifically relating to facebook, including those of stutzman, gross and acquisti, and govani and pashley. results from all three studies revealed strikingly close findings. individuals who participated in the studies seemed willing to dis­ close personal information about themselves—such as photos and sometimes even phone numbers and mailing addresses—on facebook profiles even though students also seemed to be aware that this information was not secure. in a study of fifty carnegie mellon university undergraduate users, govani and pashley concluded that these users “generally feel comfortable sharing their per­ sonal information in a campus environment. participants said they “had nothing to hide” and “they don’t really 26 information technology and libraries | march 200726 information technology and libraries | march 2007 care if other people see their information.”21 a separate study of more than four thousand facebook members at the same institution by gross and acquisti echoed these findings.22 comparing identity elements shared by members of facebook, myspace, friendster, and the university of north carolina directory, stutzman discov­ ered that a significant number of users shared personal information about themselves in online social networks, particularly facebook, which had the highest level of campus participation.23 gross and acquisti provide a list of explanations suggesting why facebook members are so open about sharing personal information online. three explanations that are particularly convincing are that “the perceived benefit of selectively revealing data to strang­ ers may appear larger than the perceived costs of possible privacy invasions”; “relaxed attitudes toward (or lack of interest in) personal privacy”; and “faith in the network­ ing service or trust in its members.”24 in public libraries, concern has primarily centered on teenagers accessing myspace.com, an online social net­ working site much larger than facebook. myspace, whose membership, unlike facebook, does not require an .edu e­mail address, has a staggering 43 million users, a num­ ber that continues to rise.25 julian aiken, a reference librar­ ian at the new haven free public library, wrote about the unpopular stance he took when his library decided to ban access to myspace due to the hysterical hype of media reports exposing the dangers from online predators lurking on the site.26 for aiken, the damage of censorship policies in libraries far outweighs the potential risk of sex crimes. furthermore, he suggests that there are even edu­ cational benefits of myspace, observing that “[t]eenagers are using myspace to work on collaborative projects and learn the computer and design skills that are increasingly necessary today.”27 what is apparent is that whether facebook continues to rise in popularity or fizzles out among the college crowd, the next generation of college students, who now constitute the largest percentage of myspace users, are already solidly entrenched and adept at using online social networks. librarians in institutions of higher education might need to consider what implica­ tions the communication style preferences of these future students could have, if any, on library services. while most of the academic attention regarding online social networks has centered on privacy concerns, perhaps the business sector has done a more thorough investiga­ tion of user behavior and students’ growing attraction towards these types of sites. business magazines have naturally focused on the market potential, growth, and fluctuating popularity of various online social networks. advertisers and investors have sought ways to capital­ ize on the exponential growth of these high­traffic sites. business week reported that as of october 2005, facebook .com had 4.2 million members. more than half of those members were between the ages of twelve and twenty­ four.28 while some portended that the site was losing momentum, as of august 2006, membership on facebook had expanded beyond eight million.29 marketing experts have closely studied, apparently more so than com­ munication scholars, the behavior of users in online social networks. in a popular business magazine, hempel and lehman describe user behavior of the “myspace generation”: “although networks are still in their infancy, experts think they’re already creating new forms of social behavior that blur the distinctions between online and real­world interactions.”30 the study of user behavior in online social networks, however, has yet to be addressed in length by those outside the field of marketing. although evidence of interest in online social net­ works is apparent in librarian weblogs and forums (many librarians have created facebook groups for their libraries), actual literature in the field of library and information science is scarce.31 dvorak questions the lack of interest displayed by the academic community toward online social networks as a focus of scholarly research. calling on academics to “get to work,” he argues “aca­ demia, which should be studying these phenomena, is just as out of the loop as anyone over 30.”32 this discon­ nect is also echoed by michael j. bugeja, director of the greenlee school of journalism and communication at iowa state university, who writes, “while i’d venture to say that most students on any campus are regular visitors to facebook, many professors and administrators have yet to hear about facebook, let alone evaluate its impact.”33 the lack of published research articles on these types of networks, however, is understandable given the newness of the technology. a few members of the academic community have sug­ gested opportunities for using facebook to communicate with and reach out to students. in a journal specifically geared toward student services in higher education, shier considers the impact of facebook on campus community building.34 although she cannot identify an academic purpose for facebook, she describes how the site can con­ tribute to the academic social life of a campus. facebook provides students with a virtual campus experience, particularly in colleges where students are commuters or are in distance education. shier writes, “as the student’s definition of community moves beyond the geographic and physical limitations, facebook.com provides one way for students to find others with common interests, feel as though they are part of a large community, and also find out about others in their classes.”35 furthermore, facebook membership extends beyond students to fac­ ulty, staff, and alumni. shier cites examples of professors who used facebook to connect or communicate with their students, including the president of the university of iowa and more than one hundred professors at duke university. professors who teach online courses make article title | author 27checking out facebook.com | charnigo and barnett-ellis 27 themselves seem more human or approachable by estab­ lishing facebook profiles.36 greeting students on their own turf is exactly the direction staff at washington university’s john m. olin library decided to take when they hired web services librarian joy weese moll to communicate and answer questions through a variety of new technologies, includ­ ing facebook.37 brian mathews, information services librarian at georgia institute of technology, also created a facebook profile in order to “interact with the students in their natural environment.”38 mathews decided to experiment with the possibilities of using facebook as an outreach tool to promote library services to 1,700 stu­ dents in the school of mechanical engineering after he discovered that 1,300 of these students were registered on facebook. advising librarians to become proactive in the use of online social networks, mathews reported that overall, his experience helped him to effectively “expand the goal of promoting the library.”39 bill drew was among the first librarians to create an account and profile for his library, the suny morrisville library. as of september 2006, nearly one hundred librarians had created profiles or accounts for their libraries on facebook. one month later, however, the administration at facebook began shutting down library accounts on the grounds that libraries and institutions were not allowed to represent themselves with profiles as though they were individu­ als. in response, many of these libraries simply created groups for their libraries, which is completely appropri­ ate, similar to creating a profile, and just as searchable as having an account. the authors of this study created the “houston cole library users want answers!” group, which currently has ninety­one members. library news and information of interest about the library is announced in the group.40 in this study, one trend the authors will try to identify is whether other librarians have considered or are already using facebook in similar ways that moll, mathews, and drew have explored as avenues for com­ municating with students or promoting library services. ■ the survey in february 2006, 244 surveys were mailed to reference or public service librarians (when the identity of those per­ sons could be determined). these individuals were chosen from a random sample of the 850 institutions of higher education classified by the carnegie classification listing of higher education institutions as “master’s colleges and universities (i and ii)” and “doctoral/ research universities (extensive and intensive).”41 the sample size provided a 5.3 percent margin error and a 95 percent confidence level. one hundred twenty­six surveys were completed, providing a response rate of 51 percent. fifteen survey questions (appendix a) were designed to target three areas of inquiry: awareness of facebook, practical impact of the site on library services, and perspectives of librarians toward online social networks. awareness of facebook a series of questions on the survey queried respondents about their awareness and degree of knowledge about facebook. the overwhelming majority of librarians were aware of facebook’s existence. out of 126 librarians, 114 had at least heard of facebook; 24 were not familiar with the site. as one individual wrote, “i had not heard of facebook before your survey came, but i checked and our institution is represented in facebook.” universities registered in facebook are easily located through a search­by­region on facebook’s home page. thirty­eight colleges and universities for alabama (jsu’s location) are registered in facebook. (in comparison, 143 academic institutions in california are listed.) out of those librar­ ians who had heard of the site, 27 were not sure whether their institutions were registered in facebook’s directory. sixty survey participants were aware that their institu­ tions were registered in the directory, while fifteen librar­ ians reported that their universities were not registered (figure 1). several comments at the end of the survey indicated that some of the institutions surveyed did not issue school e­mail accounts, making membership in facebook impossible for their university. interestingly, out of the sixty individuals who could claim that their universities were in the directory, 34 percent have created their own personal facebook accounts and two libraries have individual profiles (figure 2). one individual who established an account on the site wrote, “personally, i’m a little embarrassed by having an account because it’s such a teeny­bopper kind of thing and i’m a little old for it. but it’s an interesting cultural phenomenon and academic librarians need to get on the bandwagon with it, if only to better understand their constituents.” another survey respondent with an individual profile on the site reported a group created by his or her institution on facebook titled “i totally want to have sex in the library.” this individual wanted to make it clear, however, that the students—not the librarians—created this group. a particularly help­ ful participant went so far as to poll the reference col­ leagues in all nine of the libraries at his/her institution and found that “only a few had even heard of facebook.” that librarians will become increasingly aware of online social networks was the sentiment expressed by another individual who wrote, “most librarians at my institu­ tion are unaware of social software in general, much less facebook. however, i think this will change in the future as social software is mentioned more often in traditional media (such as television and newspapers).” according to survey responses, it does not appear 28 information technology and libraries | march 200728 information technology and libraries | march 2007 that use of facebook by students has been as noticeable or distracting in other libraries as it has been at hcl. when asked to describe their observation of student use of library computers to access facebook, 56 percent of those surveyed checked “rarely to never.” only 20 percent indicated “most of the time” to “all of the time” (table 1). however, it is important to remember that only sixty individuals could verify that their institutions are regis­ tered on facebook. through comments, some librarians hinted that “snooping” or keeping mental notes of what students view on library computers is frowned upon. it simply is not our business. “we do not regulate or track student use of computers in the library,” wrote one indi­ vidual. several librarians noted that students were using facebook in the libraries, but more so on personal laptops than public­access computers. practical impact of facebook another goal of this study was to find out whether facebook has had any real impact on library services, such as an increase in bandwidth, library traffic, and noise, or in use of public­access computers, scanners, or other equipment. student complaints about monopolization of computers for use of facebook led administrators to block the site from computer labs at jsu. access to facebook on public­access terminals, however, was not regulated. survey responses revealed that facebook has had minimal impact on library services elsewhere. only one library was forced to develop a policy for specifically addressing computer­use concerns as a result of facebook use. one individual mailed the sign posted on every computer terminal in the library, which states, “if you are using a computer for games, chat, or other recreational activity, please limit your usage to thirty minutes. computers are primarily intended for academic use.” another librarian reported that academic computing staff had to shut down access to facebook on library computers due to band­ width and access issues. this individual, however, added, “interestingly, no one has complained to the library staff about its absence!” given a list of possible effects facebook may have had on library services and operations, 10 per­ cent of respondents indicated that facebook has increased patron use of computers. seven percent agreed that it has increased patron traffic, and only 2 percent reported that the site has created bandwidth problems or slowed down internet access. only four individuals received patron complaints about other users “tying up” the computers with facebook (figure 3). since the advent of facebook, the public scanner has become one of the hottest items in hcl. librarians at jsu know that use of the scanner has increased tremendously due to facebook because the scanner used by students to upload photos is attached to a public workstation next to the general reference desk. students often ask questions about uploading pictures to their facebook profiles as well as how to edit photos (e.g., resizing and cropping). one survey question asked whether scanner use had increased as a result of facebook. of the sixty­two respon­ dents who answered this question (it was indicated that only those libraries that provide public access to scanners should answer the question), 77 percent reported that figure 1. institutions added to the facebook directory figure

scanner or pro­ vided any other type of assistance, for that matter, with facebook. the assistance the two librarians gave included scanning photographs, editing photos, uploading photos to facebook profiles, and creating accounts. however, in a separate question, 21 percent of participants agreed that librarians should be responsible for helping students, when needed, with questions about facebook. no librar­ ian has added additional equipment such as computers or scanners as a result of facebook. only one individual reported future plans by his/her library to add additional equipment in the future as a result of heavy use of the site. perspectives toward facebook one of the main goals of the study was to obtain a snapshot of the perspectives and attitudes of librarians toward facebook and online social networks in general. most of the librarians surveyed were neither enthusiastic nor disdainful of facebook. a small group of the respon­ dents, however, when given the chance to comment, were extremely positive and excited about the possibilities of online social networking. twenty­one individuals saw no connection between libraries and facebook. sixty­ seven librarians were in agreement that computer use for academic purposes should take priority, when needed, over use of facebook. however, fifty­one respondents indicated that librarians needed to keep up with internet trends, such as facebook, even when such trends are not academic in nature (table 2). out of 126 librarians who completed the survey, only 23 reported that facebook has generated discussion among library faculty and staff about online social networks. on the other hand, few individuals voiced negative opinions toward facebook. only 5 percent of those surveyed indicated that facebook annoyed faculty and staff. one individual wrote, “i don’t like facebook or most social networking services. they encourage the formation of cliques and keep users from meeting and accepting those who are different than themselves.” comments like this, however, were rare. although the majority of librarians seemed fairly apa­ thetic toward facebook, few individuals expressed nega­ tive comments toward the site. few librarians indicated that facebook should be addressed or regulated in library policy. most individu­ als viewed the site as just another communication tool similar to instant messaging or cell phones. in fact, while most librarians did not express much interest in facebook, many were quite vocal about not regulating its use. the following comment by one survey partici­ pant captures this sentiment: “attempts to restrict use of facebook in the library would be futile, in my opinion, in the same way it is now impossible to ban use of usb drives and aim in academic libraries.” while most indi­ table 2. access, assistance, and awareness of facebook and similar trends: perspectives total percentage computer use for academic purposes should take priority, when needed, over use of facebook. 67 53 librarians need to “keep up” with internet trends, such as facebook, even when these trends are not academic in nature. 51 40 library resources should not be monopolized with use of facebook. 35 28 librarians should help students, when able, with questions regarding facebook. 27 21 there is no connection between libraries and facebook. 21 17 student use of facebook on library computers should not be regulated. 15 12 library computers should be available for access to facebook, but librarians should not feel that it is their responsibility to assist students with questions regarding the site. 11 9 (respondents were allowed to check any or all responses that applied.) figure 3. patron complaints about facebook 30 information technology and libraries | march 200730 information technology and libraries | march 2007 viduals agreed that academic use of computers should take priority over recreational use, a polite request that a patron using facebook allow another student to use the computer for academic purposes, when necessary, appears more preferable than the creation and enforce­ ment of strict policies. as one librarian put it, “i don’t want students to see the library as a place where they are ‘policed’ unnecessarily.” when asked if facebook serves any academic pur­ pose, 54 percent of those surveyed indicated that it does not, while 34 percent were “not sure.” twelve percent of the librarians identified academic potential or pos­ sible benefits of the site (figure 4). the authors were surprised to find that 46 percent of those surveyed were not completely willing to dismiss facebook as pure rec­ reation. some librarians found facebook to be a distrac­ tion to academics: “maybe i’m old fashioned, but when do students find time for this kind of thing? i wonder about the impact of distractions like this on academic pursuits. there’s still only twenty­four hours in a day.” another individual asked two students who were using facebook in the library what they thought of the site and they admitted that it was “frequently a distraction from academic work.” for the 34 percent who were not sure whether facebook has any academic value, there were comments such as “i am continuing to observe and will decide in the future.” academic uses for facebook included suggestions that it be used as a communication tool for student collaboration in classes (facebook allows students to search for other students by course and sec­ tion number). one individual suggested it could be used as an “online study hall,” but then wondered if this might lead to plagiarism. some thought instructors could somehow use facebook for conducting online discussion forums, with one participant observing “it’s ‘cooler’ than using blackboard.” “building rapport” with students through a communication medium that many students are comfortable with was another benefit mentioned. respondents who were enthusiastic about facebook thought it most beneficial as a virtual extension of the campus. facebook could potentially fill a void where face­to­face connections are absent in online and dis­ tance­education classes. several librarians suggested that facebook has had a positive influence in fostering col­ legiate bonds and school spirit. as one individual wrote, “[t]he academic environment is not only responsible for scholarly growth, but personal growth as well. this is just one method for students to interact in our highly techno­ logical society.” facebook could provide students who are not physically on campus with a means to connect with other students at their institutions who have similar academic and social interests. some librarians were so enthusiastic about facebook that they suggested libraries use the site to promote their services. using the site to advertise library events and creating online library study groups and book clubs for students were some of the ideas expressed. one librar­ ian wrote: “facebook (and other social networking sites) can be a way for libraries to market themselves. i haven’t seen students using facebook in an academic manner, but there was a time when librarians frowned on e­mail and aim too. if it becomes a part of students’ lives, we need to welcome it. it’s part of welcoming them, too.” more librarians, however, felt that facebook should serve as a space exclusively for students and that librarians, profes­ sors, administrators, police, and other uninvited folks should keep out. furthermore, as one individual noted, it is not “an appropriate venue” for librarians to promote their services. while the review of literature demonstrates that much has been made of online social networks and privacy issues, the librarians surveyed were not particularly con­ cerned about privacy. only 19 percent indicated that they were concerned about privacy issues related to facebook. however, some librarians voiced concerns that many stu­ dents are ignorant about the risks of posting personal infor­ mation and photographs on facebook and do not seem fully aware of the possibility that individuals outside their social sphere might also have reason to access the site. one individual mentioned that the librarians at her institution have begun to emphasize this to students during library instruction sessions on internet research and evaluation. ■ limitations several limitations to this study must be noted when attempting to reach any type of conclusion. participants who had never heard of facebook obviously could not answer any questions except that they were not famil­ iar with the site. some questions required respondents to “guesstimate.” unless librarians have access to their figure 4. finds conceivable academic value in facebook article title | author 31checking out facebook.com | charnigo and barnett-ellis 31 institution’s internet usage statistics, it would be hard for them to really know how much bandwidth is being used by students accessing facebook. librarians, having been trained in a profession that places a high value on freedom of access, might also be wary of activities that suggest any type of censorship. therefore, it is conceivable that some of the librarians surveyed do not know whether students are using facebook in the library because they make a point not to snoop or make note of individual web sites that students view. ■ discussion while online education is growing at a rapid rate across the united states, so is the presence of virtual academic social communities. although facebook might prove to be a passing fad, it is one of the earliest and largest online social networking communities geared specifically for students in higher education. it represents a new form of communication that connects students socially in an online environment. if online academics have evolved and continue to do so, then it is only natural that online academic social environments, such as facebook, will continue to evolve as well. while traditionally considered the heart of the campus, one is left to ponder the library’s presence in online academic social networks. what role the library will serve in these environments might largely depend on whether librarians are proactive and experi­ mental with this type of technology or whether they simply dismiss it as pure recreation. emerging technolo­ gies for communication should provoke, at the very least, an interest in and knowledge of their presence among library and information science professionals. this survey found that librarians were overwhelmingly aware of and moderately knowledgeable about facebook. some librarians were interested in and fascinated with facebook, but preferred to study it as outsiders. others had adopted the technology, but more for the purpose, it would seem, of having a better understanding of today’s students and why facebook (and other online social net­ working sites) appeals to so many of them. it is apparent from this study that there is a fine line between what now constitutes “academic” activity and “recreational” activity in the library. sites like facebook seem to blur this line fur­ ther and librarians do not seem eager or find it necessary to distinguish between the two unless absolutely pressed (e.g., asking a student to sign out of facebook when other patrons are waiting to use computers for academic work). one area of attention this study points to is a lack of con­ cern among librarians toward the internet and privacy issues. some individuals surveyed suggested that librari­ ans play a larger role in making students aware that people outside their society of friends—namely, administrative or authority figures—have the ability to access the informa­ tion they post online to social networks. participants were most enthusiastic about facebook’s role as a space where students in the same institution can connect and share a common collegiate bond. librarians who have not yet “checked out” facebook might consider one individual’s description of the site as “just another ver­ sion of the college yearbook that has become interactive.”42 among the most cherished books in hcl that document campus life at jsu are the mimosa yearbooks. alumni and students regularly flip through this treasure trove of pho­ tographs and memories. no administrator or librarian would dare weed this collection or find its presence irrele­ vant. while year books archive campus yesteryears, online social networks are dynamically documenting the here and now of campus life and shaping the future of how we communicate. as casey writes, “libraries are in the habit of providing the same services and the same programs to the same groups. we grow comfortable with our provision and we fail to change.”42 by exploring popular new types of internet services such as facebook instead of quickly dismissing them as irrelevant to librarianship, we might learn new ways to reach out and communicate better with a larger segment of our users. ■ acknowledgements the authors would like to acknowledge stephanie m. purcell, student worker at the houston cole library, for her excellent editing suggestions and insight into online social networks from the student’s point of view, and john­bauer graham, head of public services at the houston cole library, for his encouragement. references and notes 1. angela reid, “finally . . . the facebook,” the chanticleer, sept. 22, 2005, 4. 2. facebook.com, http://www.facebook.com/about.php (accessed dec. 2, 2005). 3.

libraries; jun 2000; 19, 2; proquest pg. 71 prospector: a multivendor, multitype, and multistate western union catalog the prospector project represents a unique union catalog. the origin, goals, and design of the union catalog that uses the inn-reach system are presented. challenges of the union catalog include the integration of records from libraries that do not use the innovative interfaces system and the development of best practices for participating libraries. t he prospector project is a union catalog of sixteen libraries in colorado and wyoming built around the inn-reach software from innovative interfaces, inc. (iii).1 in 1997, the colorado alliance of research libraries (the colorado alliance) and the university of northern colorado submitted a joint grant proposal to create a regional union catalog for many of the major academic and public libraries in the region. the project would allow users to view library holdings and circulation information with a single query of the central database. the union catalog also would allow patrons to request items from any of the participating libraries and have them delivered to a nearby local library. however, unlike many of the other union catalogs in the country, prospector has several unique elements: • it is multistate (colorado and wyoming). • it is multisystem (incorporating systems from innovative interfaces and carl corporation; plans call for voyager from endeavor). • it is multi-library-type (academic, public, and special libraries). regional union catalogs representing the cataloged collections of libraries that are related by geography, subject, or library type have been extant for many years. early leaders in the field spearheaded locally developed systems such as the university of california's melvyl system and the illinois library computer systems organization's (ilcso) illinet online system, which became operational in 1980.2 the commercial integrated library system market began to emerge in the late 1980s and the 1990s with such vendors as innovative interfaces and its work with ohiolink through its inn-reach union catalog product, and the carl system.3 many major vendors now have union catalog solutions for a single physical union catalog, although most have the requirement that participating libraries all use the same integrated library system. an alternative approach that is also becoming popular, because of the heterogeneous nature of the ils marketplace and the widespread implementation of z39.50, is for libraries to create virtual union catalogs through broadcast searching. this solution is available from many ils vendors as well as through organizations such as oclc and its webz software. carmel bush, william a. garrison, george machovec, and helen i. reed there is not a single "right" answer for whether regional catalog searching and document delivery is best accomplished through a physical or virtual union catalog. each solution has benefits and drawbacks that must be balanced against the mix of vendors, economics, politics, and technical issues within a state. prospector is somewhat unusual in that it does create a single physical union catalog but allows for the incorporation of other library systems, made possible through a published specification from innovative interfaces. i prospector history, funding, and project goals colorado has a long history of resource sharing through a variety of programs, including use of the colorado library card statewide borrower's card and access to individual libraries' online catalogs through the access colorado library information network (aclin) and other regional catalogs. the colorado alliance has taken a leadership role within the state in promoting cooperation among major academic and public libraries in the areas of automation, joint acquisitions, and other cooperative endeavors. existing online catalog software enabled patrons to easily search individual online catalogs, but searching several catalogs was a tedious task requiring many steps. it has long been a goal of the alliance to have a true union catalog of holdings for all member libraries. to forward this goal, in 1997 the colorado alliance of research libraries and the university of northern colorado jointly applied for and received a grant from the colorado technology grant and revolving loan program to establish the colorado unified catalog, a unified catalog of holdings for sixteen of the major academic, public, and special libraries in colorado.4 the university of wyoming was included in the project through separate funding. the grant of $640,000 was used to develop a union catalog that would support searching and patron borrowing from a single database. the colorado alliance carmel bush (cbush@manta.library.colostate.edu) is assistant dean for technical services at the colorado state university libraries, fort collins; william a. garrison (garrisow@ spot.colorado.edu) is head of cataloging at the university of colorado at boulder (colo.) libraries; george machovec (gmachove@coalliance.org) is the associate director of the colorado alliance of research libraries, denver; and helen i. reed (hreed@unco.edu) is associate dean, university of northern colorado libraries, greeley. prospector i bush, garrison, machovec, and reed 71 reproduced with permission of the copyright owner. further reproduction prohibited without permission. and the university of northern colorado contributed an additional $189,500 of in-kind services to the unified catalog project. additionally, the colorado alliance contributed $119,000 of in-kind funds to support purchase of distributed system software. the colorado unified catalog project, later named prospector, was based upon the inn-reach software developed by innovative interfaces, inc. it included all innovative interfaces sites in colorado as of december 1996 as well as the carl system sites that were members of the nonprofit colorado alliance of research libraries.s the colorado unified catalog project had two major goals: • the development of a global catalog database containing the library holdings of the largest public and academic libraries in the region; and • the development of an automated borrowing system so that users at any of the participating libraries could easily request materials electronically from any other participating libraries.6 the union catalog would allow users to view library holdings and circulation information on titles with a single query of the global database. once titles were located, patrons could request available items and have them delivered to their home library. the grant proposal identified four major goals and outcomes of the project: access, equity, connections, and content and training. by creating a global catalog, the colorado unified catalog project would provide students, faculty, staff, and patrons free and open access to the union catalog via the internet. patrons from all participating libraries would have equal access to the combined holdings of all sixteen participating libraries, thus greatly enhancing resources available to patrons without the necessity of travel across the state. connectivity was greatly enhanced by the installation of high-speed internet access in the colorado alliance office where the union catalog server was housed. the unified catalog project amassed, in one place, the complete cataloged collections of the major libraries in the region creating a single, easy-to-use public interface. training for the catalog would be conducted in each library so that it could be integrated into the standard training and reference services of each participating library.? addressing statewide goals for libraries, the colorado unified catalog was designed to dovetail with an existing project in colorado called the access colorado library and information network (aclin) in several ways. the goal of aclin was to provide statewide searching of several hundred library catalogs in colorado through broadcast 239.50 searching. however, because of the large number of online library catalogs (too many z39.50 targets cause broadcast searching to be slow) and 72 information technology and libraries i june 2000 poor network infrastructure in some parts of the state, the creation of physical union catalogs, such as prospector, greatly enhanced the ability for a project such as aclin to be successful. as stated in the grant proposal it will: • make aclin more efficient since sixteen libraries will be grouped together and can be accessed via a single search, thus saving alcin users steps in searching; • enhance aclin's document delivery plans since patrons can make requests themselves; • offer both web and character interfaces for various levels of users; • provide access via aclin's dial-in ports as well as via the internet; and • support alcin's future developments based on a 239.50 environment.s work on the development of the colorado unified catalog began in mid-1997. even while contract negotiations were underway in midto late 1997, groups were busy undertaking discussions on the design and structure of the unified catalog. work on development of profiling and system specifications continued through july 1998. this data was entered onto the server at the colorado alliance office and a test database was created in august 1998. testing was completed in november 1998 and the first records were loaded in december 1998. the creation of the database for the first twelve libraries took seven months. during the database load the catalog was available for searching, although most participating libraries did not highlight the system in their local opacs. innovative interfaces, inc. conducted training on the actual patron requesting and circulation functions at three sites over the period from may through july 1999. as of january 2000 the catalog included more than 3.6 million unique bibliographic records of the twelve largest libraries in colorado (more than 6.6 million marc records have been contributed, which has resulted in 3.6 million unique records after de-duplication). with the database in place and opac and circulation training complete, prospector went "live" for patron-initiated requests in the first eight libraries on july 23, 1999. as of december 31, 1999, all twelve innovative sites were "live" in prospector. the final programming for loading the records from carl-system sites will be completed in spring 2000. it is anticipated that carl-system library records will be loaded in late spring 2000 and will bring the database to more than five million unique marc records, with more than ten million item records. since the receipt of the grant, two participating libraries have selected endeavor as their online integrated system . contract negotiations are underway between innovative interfaces and the reproduced with permission of

marketing of prospector planning and policy making are inherently political processes in which participants choose among goals and options in order to make decisions and to direct actions. for prospector the diverse makeup of multitype libraries and multisystems augured for different perspectives on implementation from the onset. nearly every department in member libraries would have an impact from the project. to be successful in carrying out their charges, the work of the task forces appointed to implement prospector had to address how these staff could influence the process and how local practices would be affected. the challenge was to engage staff in the process since the task force structure precluded representation from every member library. meeting this challenge would be vital to ensuring input and fostering buy-in and advocacy for prospector in member institutions. consequently, in addition to reviewing standards or best practices and focusing on the goals stipulated in the grant, obtaining factual knowledge about member practices and resources and encouraging communications served as key ingredients in planning and policy development. general process profiling prospector, a main charge for the cataloging/ reference task force, illustrates the general process employed in planning and how key ingredients were applied to gain input and produce results. the first step involved the task force's review of the grant's aims for the unified catalog. with that framework as a basis, a planning process was outlined and shared with participants. the prospector web site detailed the specification development process, including the schedule and opportunities for input. next the task force surveyed participants for information on their systems: bibliographic indexing rules, types of indexes, characters indexed in phrase indexes, indexes on which authority control performed, and suppliers of authority records. using this data, the task force identified the commonalties and differences to determine what to create in the unified catalog. members also consulted innovative interfaces and reviewed what previous innreach customers had established. draft recommendations for indexing, indexes, record overlay, and record display specifications were then posted on the prospector web site and participants requested to review and provide input. a notice in data/ink: the alliance newsletter (www.coalliance.org/ datalink) also referenced the site. at the same time, testing was performed using draft specifications in order to assess them and to check for other concerns that testing might reveal. because of the importance of the recommendations, an open forum was held to receive additional comments. following the forum, the task force members made final adjustments to the specifications. after the period for public comment ended, the specifications were submitted as recommendations to the prospector steering committee for approval. once approved, the specifications became official and were referenced in all site visits. issues because of the design of inn-reach, participants must make decisions about contribution of records, priorities for what record would serve as the master record, order of loading, indexing, indexes, and displays for the unified catalog. circulation functions require decisions about services for patron types, circulation statuses, loan periods, numbers of loans, renewals, recalls, checkouts, holds, overdues, fines, notices, pick-up locations, and billing. in the case of prospector, expectations regarding what would be controversial met with a few surprises. for example, the master record, the bibliographic record from one participating library to which holdings of other libraries are displayed, is based upon encoding level and the library priority list. the latter determines if the incoming record should replace an existing level; a record with a higher level will replace a lower one. based upon the data collected from libraries, a proposal categorized libraries into the following order: large, special, and "all others." the order was further factored by a member library's application of authority control and participation in program for cooperative cataloging programs. the proposal drew minimal comment from libraries. pride of ownership was not an obstacle. everyone was committed to the fullest authorized form of the record. how many loans an individual could request was the subject of early debate. there were concerns about discrepancies between local limits for borrowing and the possible setting of a higher number of loans on prospector. a corollary concern was that a high number might result in depleting a member library's collection. previous experience with borrowing by a subset of members shed light on the issue; there were no problems with loan limits. in fact, inn-reach supports "load leveling" across participating libraries randomly as well as by prospector i bush, garrison, machovec, and reed 73 reproduced with permission of the copyright owner. further reproduction prohibited without permission. precedence tables thus avoiding systematic checkout from one library only. members decided that they could always pass a request on to another owning library if necessary and monitor loans to determine if any abuses would develop. with these options, it then became possible to establish a forty checkout limit for individual patrons in prospector. differences in cataloging practices engendered more discussion because of the potential for a policy that might affect local practice. in the course of comparing practices of institutions, the cataloging/reference task force identified multiple records for the same serial titles that reflected differences in forms of entry and multiple versions treated either in separate records or on the same record. there was wide variety in statements of holdings. these differences warranted gathering further information on holdings; multiple versions, especially those involving electronic versions; and successive/latest entry for cataloging. the task force decided to hold a focus group on serials and invited staff in member libraries from serials, cataloging, and reference to attend. in the meantime, visits to participating libraries were instituted, the first of the roadshows, to discuss serials practices, their implications for overlays and displays, and options for handling them. the focus group attracted a large attendance and proved useful in gathering information about practices and the concerns of participating libraries regarding serials. most libraries reported individual practices for recording holdings. although participants expressed a desire for consistency, attendees also shared that resources are not available to retroactively change them. instead attendees encouraged development of a best practice recommendation that would follow the niso standards for those libraries wishing to change practices. with the exception of electronic versions of serials, focus group participants had no problem with multiple formats in the same bibliographic record as long as it was clear to users. electronic versions prompted a lot of questions about what to do with 856 links to restricted access resources and about changes in software. it was clear that this issue would need further investigation by the task force. the hottest area, successive or latest entry cataloging of serials, registered strong preferences by proponents. attendees did not welcome changing practice in either direction. instead there were questions asked about possible system changes and about the conduct of use studies to determine what problems might arise from latest entry records in the system. with the information gained from the focus group meeting, the task force assigned priority to the areas and pursued latest/ successive entry as the top priority. 74 information technology and libraries i june 2000 already the task force had consulted innovative interfaces, inc. and received a negative reply to possible changes to matching algorithms, loading programs, and record values that could deal with practices of participants because of the software structure. it was technically impossible for a latest entry and successive entry record to load separately given their match on the oclc number. the predominant use of successive entry and its status as the current national standard persuaded the task force initially to recommend coding latest entry in a special way so that the record for such an entry would not be the master record in the system unless it was unique. this interim measure led to the policy recommendation that successive entry serve as the standard for prospector. as a part of the recommendation, members are asked to not undertake retroactive conversion/ recataloging projects to change existing latest entry records. up to the meeting of the prospector board of directors, the serials policy was argued. the approval by the board illustrates that controversial issues may require that leadership commit their libraries to policies. marketing marketing incorporates an overall strategy of identifying patrons' needs, designing products to meet those needs, implementing the products, and promoting and evaluating them. the twin goals of prospector are: (1) one-stop shopping and expanded access regardless of location, and (2) an automated borrowing system to facilitate fast delivery of materials that addressed problems experienced by patrons in searching and obtaining materials. the grant proposal outlined a plan for member libraries to meet these goals through inn-reach software and the cooperative efforts of participating members. with the implementation of the unified catalog and patron-initiated borrowing, the next pieces of the strategy, promotion and evaluation, come into play. member libraries commitment to a cooperative venture takes time and energy. the support for prospector at the library director and dean level had to be translated to staff in member libraries whose efforts would be necessary to support the unified catalog and patron-initiated loans. staff members had to become acquainted with how prospector would benefit patrons and their work. hence internal promotion was a necessary component throughout planning and policy development and with implementation to users. because of the numbers of staff in member libraries, no one method would assure awareness of developments for prospector. the approach involved the alliance's newsletter (datalink), a prospector web site, electronic reproduced with permission of the copyright owner. further reproduction prohibited without permission. discussion lists, e-mail, correspondence, phone calls, documentation, training sessions, and many site visits. the site visits facilitated interaction across institutional lines and were important for discussing critical issues at the local level. in arranging for site visits, it was important to clarify what the staff members wanted to discuss. a general update on prospector might be followed by other technical sessions such as preparing the library's database for load into the prospector system. participants' questions emphasized the importance of sharing the plan for developing prospector and the basic concepts guiding the implementation planning and policy process as listed below. these concepts bore repeating because a staff member could have been hearing about prospector for the first time. • decisions and directions are guided by data and input gathered from participants, standards/best practices, system capabilities, and the aims for prospector described in the grant. • relatively few local practices are affected by participating in prospector. • inclusiveness in record contributions would build prospector into a rich resource for users; however, participating libraries can exert control over contributions. • global policies are developed for prospector only; local sites define their own local policies. • assistance is available to participating libraries in coming up with solutions for special circumstances. • prospector is not reinventing the wheel. although the multitype library and multisystem involvement would produce a new model of inn-reach, other inn-reach sites could serve as models. • think globally but act locally. more than a catchphrase, this statement acknowledges the reality of individual library circumstances and the balancing of prospector goals to maximize access and use of resources by patrons. patrons the design of the pac, a promotional brochure, and individual library public relations efforts all served to promote prospector's availability to users. prospector provides access via telnet and the web. the impetus, however, was to examine member webpacs and create a prospector webp ac that exemplified the best in menu design including caption descriptions, navigational aids, and consistency in display of elements among search screens. special attention was paid to providing example searches that would have appeal for the diversity of patrons served by the membership. after mulling over several name possibilities, the alliance staff suggested the name prospector for the unified catalog, connoting the rich mining history of the rocky mountain area. this identity found its depiction in a classic picture of a gold miner supplied by the colorado historical society. representing the user, the miner is the center panning for gold, an apt image for users exploring the richness of resources from the unified catalog. the incorporation of the image as the logo on the web site and the catalog was followed by its adoption for the entire cooperative venture. name recognition spread quickly. to facilitate promotion at member libraries, the alliance staff designed a brochure. the design features a brief description of the unified catalog, a list of members and information for patrons on how to connect, what's available on prospector, how to use the self-service borrowing, and how to view their circulation record. many libraries have web-mounted guides or paper handouts in their instructional service, using the alliance-designed brochure as a model. finally, staff in member libraries exercised individual approaches to promote prospector to users. denison library describes and provides a link to prospector on its web list of databases and help guides. colorado state university libraries devoted the front page of its library newsletter to "hunting for hidden gold," the introduction of prospector. a special newsletter for auraria's history faculty highlighted prospector in its database news section. the university libraries of the university of colorado at boulder describes the unified catalog in its web site on its state services page. more introductions came from instructional classes held by every member library. profile of participating libraries prospector is unique since it is multistate, multi type, and multisystem. of the sixteen members (see appendix a), almost all are located along the front range of the rocky mountains extending from laramie, wyoming, southward to colorado springs, colorado. only fort lewis college is located on the western slope of the mountains. despite the distances, a network of courier service connects all members. within the membership are eleven public and private academic libraries, three special libraries representing law and medicine, and two public libraries that serve almost one million registered patrons. twelve of the libraries operate innopac and are loaded into prospector. two libraries on the carl system are slated for loading in mid-2000. two other libraries are migrating to the voyager system by endeavor information systems in the summer of 2000. hopes are to incorporate them into the system in 2001. prospector i bush, garrison, machovec, and reed 75 reproduced with permission of the copyright owner. further reproduction prohibited

after databases are loaded initially, the software automatically queues transactions that occur to bibliographic, item, order, or summary serial holdings records and sends those transactions up to the central catalog. staff in the local library has no extra work or steps to take to send transactions to the union catalog. the union catalog uses a "master" record to maintain only one bibliographic record per title. the "owner" of the master record is determined by several factors. a bibliographic record with only one holding library automatically has that library as the owner of the master record. if more than one library holds a title, the system uses an algorithm to determine which record coming into the system has the highest encoding level. the library that has the record with the highest encoding level becomes the owner of the record, and its version of the record is displayed and indexed in the catalog. in addition, a table is created which has a list of the libraries in priority order for determining the master record if two or more matching records enter the system with the same encoding level. for the prospector catalog, a survey was conducted of the participating institutions to determine which libraries might have the best or fullest records. questions in the survey included size of database, source of bibliographic records, participation in national projects (e.g., program for cooperative cataloging, oclc enhance), amount of authority work done and level of authority control in the local database, level of cataloging given to records, and type of institution. the task force charged with designing the catalog examined these surveys and determined a priority order of the participating institutions for selecting bibliographic records. the system also uses a set of match points each time a bibliographic record is added to the union catalog. whenever a match occurs, the system examines the encoding level of the incoming record and the library from which the record is coming to determine if a change in the master record is required. the existing record is overlaid by the incoming record if the master record holder is changed. the first check is done on the oclc record number. if there is a match on that, the system adds the holdings to the existing record. if there is no match on the oclc number, the system attempts to match on the isbn or issn in combination with the title in the 245 field. again, if a match occurs, the system adds the holdings to the existing record. if no match occurs, a new bibliographic record is added to the catalog. in addition, each library that has a local innovative interfaces system has the ability to exclude bibliographic, item, order, or check-in records from being sent to the 76 information technology and libraries i june 2000 union catalog. suppression may occur in each of these record types. the library may also choose to send a record to the union catalog but exclude it from public display in the union catalog or to suppress a record from displaying in the public catalog both locally and centrally. the inn-reach system has no central database maintenance module, though it does provide a staff mode in which to view records, to create lists, and to monitor transaction queues. the staff module that is available via a telnet connection allows authorized users to view those records that have been contributed to the union catalog but are not displayed to the public in the union catalog. for example, a library may contribute its order records to the union catalog but choose to suppress those records from public display; however, authorized staff may view these records in the inn-reach staff mode or create lists for collection development purposes that include those order records. circulation status of individual items and volumes also appears to the user. the prospector member libraries with local innovative interfaces systems also maintain a set of circulation or item status codes that display various messages to users of their individual public catalogs. the inn-reach system also has a set of circulation or item status codes. agreement was reached on what the status codes were to be in the central catalog, and each member library then had to map its local codes to the codes used in the central catalog to ensure proper message display in the union catalog. in some cases, the member libraries had to adjust local status codes. indexes for the prospector catalog were determined during the profiling process. in general, there are more indexes in the union catalog than are available in the member libraries' local catalogs. indexes in prospector include author, author/ title, library of congress subject headings, medical subject headings, library of congress children's subject headings, journal title, keyword, library of congress classification numbers, national library of medicine classification numbers, dewey decimal classification numbers, government documents numbers, oclc numbers, and special numbers (e.g., isbn, issn, music publisher numbers, etc.). the classification number indexes are derived using the classification numbers that appear in the defined marc tags for the various classification schemes in the bibliographic record and do not represent local call numbers. local call numbers are always stored at the item record level in the union catalog. it was decided that many local marc fields that are defined for local notes or local access would not transfer from the local catalog to the union catalog (e.g., 59x, 69x, 79x, 9xx) to avoid ambiguities and excessive heading conflicts. therefore, there may be access points or index entries in the local catalog that may not be available in the union catalog; the local reproduced with permission of the copyright owner. further reproduction prohibited without permission. catalog may still contain "richer" or "fuller" searching than the union catalog. the local catalog may have materials accessible in it as well that do not appear in the union catalog. patrons using a local catalog may transfer their searches up to prospector simply by clicking on a button in their local public catalogs and have the search automatically occur in the union catalog. patrons may access prospector directly either via the world wide web or via telnet. navigation between local catalogs and prospector as well as navigation within prospector has been designed to be clear and simple. patrons may also go from prospector either back to their local catalog or to the local catalogs of other member libraries. when a patron locates an item that he or she wishes to borrow from prospector, he or she may initiate the request for the item online. the borrowing and lending process is described below. prospector member libraries have been asked to be as inclusive as possible in contributing bibliographic records to the union catalog. member libraries have been asked to contribute the following: • items that users may borrow, including all monographic materials that circulate, and other material types as specified by individual institutions that are listed as available for circulation. • items that users may not borrow but may use onsite, including reference materials, archival materials, rare books, and others as determined by individual institutions. virtual items, such as electronic journals, which have ip limiting and authentication are included in this category. • items that are owned virtually which have urls or ip addresses that are open and unrestricted include government publications and selected home pages as determined by the local institution. bibliographic records that are contributed should have as full cataloging as possible for identification and retrieval. materials that are on reserve and other locally defined special materials (e.g., materials that have use restrictions placed upon them) may be excluded from prospector. the prospector union catalog will also include bibliographic and circulation information from libraries that do not use innovative interfaces as their local system vendor. i the integration of non-innovative libraries into inn-reach one of the major efforts in the prospector project was to be able to incorporate bibliographic, item, summary serial holdings, and acquisitions records from other vendors with the inn-reach union catalog software. in 1997, when the grant was written, it was envisioned that the system would incorporate libraries using two ils vendors-innovative interfaces, inc. and carl corporation-two of the major vendors in colorado at the time. twelve libraries used innovative interfaces and four used the carl system (denver public library, regis university, colorado school of mines, and the university of wyoming). however, in late 1999, the colorado school of mines and the university of wyoming decided to migrate to the voyager system by endeavor information systems (this is occurring in 2000). both of these institutions have still expressed an interest in being part of prospector, so they will need to be integrated in 2001 after they are stable on their new system. the remaining carl sites will be fully integrated in 2000. the integration of records that allows document requests from different vendors is being accomplished as follows: • innovative interfaces, inc. has published a set of specifications for how bibliographic, item, summary serial holdings, and acquisitions order records should be formatted to be loaded into the union catalog. • published specifications were also created for patron verification and for how document requests are to be transferred. • the alliance office is developing the software to package usmarc bibliographic records, item records, summary serial holding records, and order records to transfer to prospector. work is also being done so that document requests may be relayed between the different systems using an intermediate unix server running an sql database with a web interface for circulation to ill staff. because the carl and endeavor systems are built differently, the record updating may be done on a "batch" basis several times a day. patron verification, to determine if a carl or endeavor patron is in good standing before allowing a document request, will be done in realtime. i administrative and committee structures under provisions of the grant, the dean of libraries at the university of northern colorado provides administrative management for the project while the colorado alliance of research libraries houses the server, maintains the union catalog software, provides network connectivity, prospector i bush, garrison, machovec, and reed 77 reproduced with permission of the copyright owner. further reproduction prohibited without permission. develops the software to integrate the non-innovative sites into the union catalog, and provides ongoing system administration support for the project. a prospector steering committee comprised of deans and directors of three participating libraries provided general overview for the project during the initial stages. to carry out the initial work of the project, two task forces were appointed with responsibility for detailed design and implementation of the system: the catalog/reference task force and the circulation/document delivery task force. the catalog/reference task force was charged with making all bibliographic and display decisions relating to the catalog. this included establishing the criteria for determining which institution's bibliographic record displays in the catalog, developing display and overlay hierarchies for bibliographic records coming into the system, and identifying marc fields that would be indexed and displayed in the catalog. membership on this task force included both public services and technical services personnel, but did not include representation from every participating library.9 the circulation/document delivery task force was charged with developing common circulation policies to be applied in the union catalog including loan periods, fines, renewals, holds, recalls, checkout limits, and patron blocks. the task force was also responsible for developing the precedence table for routing patron requests. the members of this task force represented each participating library, and several libraries had representation from both their circulation and interlibrary loan department.lo these two task forces conducted meetings from july 1997 through december of 1999. the stage was set for the task forces' work at a training session held by innovative interfaces, inc. on system operation and functionality. each group received direction on what policy issues needed to be determined to lay the groundwork for establishing the codes that drive system functionality. after the initial training, each task force met several times a month, often consulting with innovative interfaces, inc. and/ or their local libraries as their planning and deliberations continued. communication was an important component during the development of the system. soon after the grant was awarded, staff from the alliance office visited each participating library and met with library personnel to explain the overall goals of the project and how work would be conducted. as detailed development progressed, open forums were held in central locations to keep representatives of all libraries apprised of progress and to get feedback regarding specific policy issues. completed work from the task forces was mounted on the prospector web site. in addition, regular articles appeared in data/ink, the alliance monthly newsletter. specific training sessions were conducted both by the task forces and by innovative interfaces. 78 information technology and libraries i june 2000 as the actual database loading process began, the catalog/reference task force conducted sessions at each prospector library. these sessions were twofold in purpose: to provide an opportunity for a general overview of how the database structure and indexing worked for all library personnel, and to train technical services personnel in how local coding of records impacted the display of their local records in the global catalog. in preparation for going live with patron requesting, innovative interfaces, inc. conducted pac searching and circulation training sessions at several central locations for frontline staff from all institutions. in addition, the circulation/ document delivery task force held a central session for representatives from all libraries to discuss issues relating to the flow of materials among libraries. during system implementation, it became apparent that some ongoing structure would be required for ongoing maintenance and development of the global catalog. in completion of their charges, each task force prepared a final report, which was submitted to the steering committee and to the prospector directors group. each task force recommended its own termination but outlined a structure to address ongoing issues. as approved by the prospector directors group, the ongoing governance structure is multilayered with frontline operations groups, broader planning and policy-setting committees, an advisory committee, a directors group, and electronic discussion lists for communication. monitoring of the day-to-day work of the cataloging and circulation/ document delivery operations is handled by frontline staff via e-mail, electronic discussion lists, and/ or telephone. broader planning and policy issues are addressed through smaller, representative standing committees. the advisory committee and directors group operate at a policy level. the new structure includes: • a catalog site liaison group comprised of one representative from each participating library and charged with serving as the point of contact for inquiries regarding catalog maintenance, access and record merging; • a catalog/reference committee comprised of members selected from the participating libraries and charged with responsibility for all bibliographic and display issues relating to prospector. this includes monitoring details of the current implementation as well as addressing ongoing policy issues, recommending system enhancements, testing new system functionality, and training staff at new sites coming into the system; • a document delivery site liaison group comprised of one or more representatives from each participating institution with responsibility to reproduced with permission of the copyright owner. further reproduction prohibited without permission. serve as a point of contact for other prospector libraries that have inquiries concerning issues, lost books, courier delivery, or related topics; • a circulation/document delivery committee comprised of representatives selected from the participating libraries and responsible for issues relating to the courier delivery service, circulation load-balancing, monitoring member compliance with circulation policies, recommending system enhancements, testing new system functionality , and the year-end reconciliation of lost book charges; and • a prospector advisory committee comprised of tewnty-four deans and directors from participating libraries to address issues requiring quick response relating to project specifications and operating rules. the prospector directors group is comprised of the deans/ directors of all participating libraries and is charged with making recommendations on high-level policy and admission of new participants . since prospector is a project of the nonprofit colorado alliance of research libraries consortium, all final high-level decisions and financial commitments are subject to the approval of the board of directors of the consortium . at the present, five of the sixteen prospector libraries are not part of the formal consortium but participate in this one project. the newly formed committees will continue to address broad policy and operational issues such as the load-balancing tables for routing patron requests to owning libraries, will document best practices for local libraries to follow in implementing certain functionality within their local system to achieve maximal results in the central catalog, will identify enhancements to the system , and will test new release functionality. i borrowing and lending policies and specifications as a prelude to its work, the circulation / document delivery task force examined borrowing and lending practice s from other innovative interfaces . inn-reach sites and reviewed the borrowing policies for consortia! borrowers that were developed and agreed to by a subset of alliance libraries (university of northern colorado, auraria library, and denver public library) several years ago. the first major duty of the task force was to establish circulation and document delivery policies that would govern those functions within the prospector system. these common circulation and document delivery policies were based on a series of assumptions: • the task force policies apply to the unified catalog only; local sites define local policies; • local workflow remains local purview; • policies should be kept simple; • circulating materials are commonly circulated materials, primarily books, at each site; • the task force will work within the confines of the inn-reach system; • if a patron is blocked locally, he or she will be blocked at the global level; • for routing purposes, each institution (rather than branch) is the routing site; and • local sites will determine when their items are declared lost. the task force established a series of recommendations for policies that applied to the prospector system . the proposed policies were discussed within the local institutions as well as with various administrative groups. the final policies for prospector lending as adopted and implemented in the system are: • loan period : twenty -one days • renewals: one • number of holds allowed : forty • checkout limit: forty items • recalls: none, except for academic library reserve collections • lost book charge: $100, which is comprised of a $75 refundable lost book charge and a $25 nonrefund able processing fee • libraries establish their own local rules for overdue fines on prospector materials . key features of the inn-reach software that were emphasized with each local library during training sessions are: • libraries have local control over what is loaned through the global catalog. • libraries have local control over which of their patrons can borrow materials through the global catalog. • if the local copy is checked out or missing, a copy may be requested through prospector. • the system is sensitive to multivolume works and allows particular volumes to be selected. the ongoing document delivery committee has developed a series of "best practices" that establish benchmark policies that each library is urged to adopt in the spirit of uniform cooperation among participating libraries. individual libraries, however, may choose not to adopt these practices. prospector i bush, garrison, machovec, and reed 79 reproduced with permission of the copyright owner. further reproduction prohibited without permission. system functionality the actual steps for a patron to request an item within the prospector system are simple and self-explanatory. once a patron has identified an item they wish to order, the following steps take place: • the user is prompted for institutional affiliation, name, and library card number. • the system checks local system to ensure that the patron is in good standing. • the user selects a pick-up location from those offered by their home institution. • the system forwards the patron request to an owning library with an available circulation status doing load balancing among the libraries with available copies. once the patron request is forwarded to a lending library, the request goes into the queue of requested items from that library. each library has established its own workflow for handling requests; however, that workflow must include interaction with the system to record the status of the request. once the item is located by the lending library, it is checked out to the requesting patron's "home" library and is sent, via courier, to that library. the "home" library then receives the item in the system and holds it pending pick-up by the patron. when the patron arrives to borrow that item, it is checked out to that patron's record according to the prospector loan rules. having a common set of loan rules for all prospector loans provides consistency for the patron. the patron may still have multiple due dates on items checked out at the same time depending on the loan rules for local checkouts. the system maintains statistics on several elements of the borrowing and lending processes. it tracks the total number of items borrowed and loaned and calculates the ratio of borrowing to lending per institution. in addition, it tracks the number of items cancelled and the reason why, the number of holds filled and cancelled, and several other groupings. i challenges and issues with the building of prospector still underway and public access available only since late july 1999, prospector is doing a respectable volume of loans in its infancy. over ten thousand items were delivered during the first six months of operation. this number is expected to dramatically rise as the system grows and as local libraries promote the service. this auspicious start provides a sense of 80 information technology and libraries i june 2000 accomplishment tempered by recognition that there is more to do. some of the major challenges facing the project include: • • • • • • • • development is underway to integrate records for the carl system libraries into the central catalog and provide borrowing capabilities for their patrons. as member libraries choose other online system providers, ideally, these systems likewise need to be interfaced with the prospector system. coming to agreements with all vendors involved will require careful negotiation and wording of contracts. discussions are underway with innovative interfaces and endeavor information systems for merging endeavor libraries into inn-reach. monitoring how the fiscal accounting for first endof-year reconciliation will work for lost books is planned. developing best practices and evaluating software enhancements for inn-reach are necessary. we need to determine how to handle electronic resources and multiple formats, and load records from commercial electronic resources, for example, net library. we must improve matching within the system and additional enhancements to the prospector web site. with growth of the system, full-time operations and management staff may be required. securing funding for the new ventures and new staffing will require development efforts or a sharing of costs by members. there is no state-based funding for ongoing maintenance and new product acquisition. with the increasing flow of materials between libraries, the courier delivery service must be monitored on an ongoing basis. the statewide courier service has been recently restructured and was contracted based on pre-prospector activity levels for interlibrary loan materials. with the ever-growing popularity of prospector, there will be a corresponding increase in volume for the courier. service levels need to be monitored closely to ensure that the speed of delivery is maintained and that the loss and incorrect routing rate is within acceptable limits. the balance of borrowing and lending will have financial impacts on some of the participating libraries. through a legislative allocation, the state library of colorado provides funding on a per transaction basis to libraries that are net lenders, or that loan more materials than they borrow. most libraries are considering the prospector transactions as equivalent to interlibrary loan transactions and counting them toward the payment for lending program. it is anticipated that the inclusion of prospector activity in the interlibrary loan borrowing and reproduced with permission of the copyright owner. further reproduction prohibited without permission. lending statistics will significantly alter the balance of payment for lending among the prospector libraries. already prospector has shown that it is changing behaviors. the cooperation between libraries has been impressive. in member libraries, staff are factoring prospector into their plans and realizing that keeping prospector operations staff informed of problems is a good habit. user searching and document delivery patterns are changing. margaret landrum, director at the fort lewis college library, predicts that prospector will have a dramatic effect on researchers in the geographic area. its start has given all members a share in that expectation. i the future and interesting spin-offs union catalog projects often take on a "life of their own" far beyond what was originally envisioned. some of the future spin-offs may include: • the addition of other research libraries in nearby states. • collection overlap studies and improved coordination on acquisition and weeding projects between libraries. • with the full implementation of the union catalog, there are opportunities for resource sharing at a broader level. the central catalog has the functionality to support bibliographic records for and access to "consortia!" resources, thus enabling libraries to jointly purchase resources and provide centralized access to them. • as database and online information providers develop new methodologies for access to their resources, there will be opportunities to easily link from either the local or central catalog to these online resources, a process which is cumbersome and/or impossible in the nonglobal environment. for instance, where databases are centrally mounted at the alliance office with shared ownership, the link to serial holdings feature is pointed to prospector, thus providing patron access to consortiawide holdings. • use of the system as a central repository for cataloged metadata for electronic resources on the web. • encouraging innovative interfaces, inc. to allow document requests that "fail" in the system to be forwarded to national ill subsystems or commercial document suppliers using national standards. i conclusion prospector dramatically alters the bibliographic landscape in colorado, offering patrons easy access to the bibliographic wealth of the state. patrons will be easily able to move from a local catalog to this regional system and request materials. librarians will find the system useful for collection overlap studies, improved coordination on acquisitions and weeding projects, z39.50 links with other indexing/ abstracting services for serials holdings information (e.g., ovid or silverplatter), and expedited book delivery. the high level of cooperation among the diverse nature of the participating libraries is exemplary. the incorporation of public and private universities, public libraries, and special libraries offers a model for cooperation. references 1. anthony j.

of interest to monitor because of the wide variety of participating libraries in the system. the incorporation of both academic and public libraries has the potential for different use patterns as seen in more homogeneous academic union catalogs. the following data represents some of the very early borrowing and lending patterns in prospector . all of the libraries in the table went "live" in terms of borrowing and lending in late july or august 1999, with the exception of jefferson county public library, which went live in november 1999. history with other similar projects has shown that use will dramatically grow as libraries and users gain familiarity with the service. the incorporation of denver public library in 2000 should provide significant impact on the service. at the present (and in the accompanying table), prospector has been configured to do random load balancing without the use of any precedence tables to force document requests to one site or another. borrowing site

learning $olutions co-coordinator, california state university, northridge. abstract digital humanities is an academic field applying computational methods to explore topics and questions in the humanities field. digital humanities projects, as a result, consist of a variety of creative works different from those in traditional humanities disciplines. born to provide free, simple ways to grant permissions to creative works, creative commons (cc) licenses have become top options for many digital humanities scholars to handle intellectual property rights in the us. however, there are limitations of using cc licenses that are sometimes unknown by scholars and academic librarians. by analyzing case studies and influential lawsuits about intellectual property rights in the digital age, this article advocates for a critical perspective of copyright education and provides academic librarians with specific recommendations about advising digital humanities scholars to use cc licenses with four limitations in mind: 1) the pitfall of a free license; 2) the risk of irrevocability; 3) the ambiguity of noncommercial and nonderivative licenses; 4) the dilemma of sharealike and the open movement. introduction along with an increasing number of digital scholarships, open access became a preferred, more affordable model for scholarly communication in the us.1 in particular, digital humanists envision a sharing culture that digital contents and tools can be widely distributed through open access licenses.2 creative commons (cc) licenses, with their promise to provide simple ways to grant permissions to creative works, became top options for many digital humanities to handle intellectual property rights in the us. however, creative commons is not a panacea for managing the intellectual property rights of digital scholarship. digital humanities projects usually consist of complicated components and their intellectual property rights involve various licenses and stakeholders. with misunderstandings of intellectual property and cc licenses, many scholars are not fully aware of the implications of using cc licenses, which cannot provide legal solutions to all intellectual property rights issues. the increasingly popular application and commercialization of digital humanities projects in the us further complicate the issue. based on case studies and influential lawsuits involving the topic in the us, this article critically investigates the limitations of using cc licenses and recommends that academic librarians provide scholars with more sophisticated suggestions on using cc licenses as well as providing education on intellectual property rights in general. mailto:yi.ding@csun.edu is creative commons a panacea for managing digital humanities ip rights? | ding 35 https://doi.org/10.6017/ital.v38i3.10714 literature review usually identified as rights experts, academic librarians are in a unique position to provide copyright education in the digital humanities field through consultation, instruction, and other means to faculty and students.3 librarians sometimes position themselves as “reuse evangelists” who embrace the vision of creative commons by applying cc licenses as well as introducing cc licenses to the campus community through guides and webpages.4 yet, few discussions have been brought up about the limitations of cc licenses in the library community.5 drawing from scholarly literature from the law field and primary sources including lawsuits, websites, magazine articles, and newspaper articles involving this topic, this article intends to bring a critical perspective into the copyright education academic librarians provide by analyzing the four limitations of cc licenses in managing digital humanities projects intellectual property rights. in the law community, scholars have examined the limitations of open licensing and creative commons. katz elaborated the mismatch of the vision of creative commons and its licensors as well as how the incompatibility of cc licenses may result in potential detriment to the dissemination of knowledge.6 scholars later have referred to katz in extensive discussions of the limitations of cc licenses in different realms of copyrighted works. for example, johnson investigated several limitations of cc licenses for entertainment media, including those with sharealike, noncommercial, and nonderivative licenses.7 lukoseviciene acknowledged the efficiency of cc licenses while pointing out its limitation in ensuring equity in a sharing culture.8 when discussing the problems of cc licenses in data sharing, khayyat and bannister echoed katz’s critique on the limitation of cc licenses in combining copyrighted works with different types of licenses.9 scholars have also addressed problems related to intellectual property rights other than copyright when applying cc licenses. for example, hietnanen discussed the problems of license interpretation and concluded that although cc licenses are useful for “low value high volume licensing,” it fails to address some important intellectual property rights including privacy and moral rights.10 burger demonstrated how cc commercial licenses have encouraged publicity right infringement in several cases.11 nevertheless, none of the above scholars discussed the implication of the limitations of cc licenses in digital scholarship. to solve the problem of excessive open-source licenses, gomulkiewicz suggested a license-selection “wizard” modeling what creative commons offers, which demonstrates the limitation of cc licenses in managing the intellectual property rights of codes, a common component of many digital humanities projects.12 this article does not aim to conduct a comprehensive assessment of pitfalls of cc licenses in digital scholarship or make legal recommendations to manage the intellectual property rights of digital humanities projects. rather, it discusses the four limitations of cc licenses that are usually overlooked but essential for academic librarians to educate patrons in the digital humanities field. with the development of the digital humanities field and more students involved in it, academic librarians should educate both faculty scholars and emerging scholars about implications of applying cc licenses.13 information technology and libraries | september 2019 36 four limitations of cc licenses is creative commons really free?—the pitfall of a free license one major reason that scholars and institutions are using cc licenses is the ease of applying them to creative works. the directory of open access journals (doaj), which is regarded as “both an important mode of discovery and marker of legitimacy within the world of open access publishing,” now recommends cc licenses as a best practice.14 doaj explicitly encourages scholars to use creative commons’ “simple and easy” license chooser tool. indeed, the creative commons website provides scholars and institutions a very user-friendly way to select and apply a license to copyrightable works.15 anyone can place a cc license on a work by copying and pasting from its website. however, this oversimplified process of handling intellectual property rights of creative works may mislead both copyright owners and copyrighted works users to overlook pitfalls of this free license, including unintentional copyright and other intellectual property rights infringements. more specifically, one prominent legal formality of cc licenses is that licensees do not need to pay to register with creative commons to apply a cc license. as indicated by creative commons website, a cc license is legally valid as soon as a user applies it to any material the user has the legal right to license. creative commons also does not “require registration of the work with a national copyright agency.”16 while copyright protection is automatic the moment a work is created and “fixed in a tangible form,” there are various advantages to register copyrighted works through the united states copyright office to establish a public record of the copyright claim.17 one foremost important advantage of copyright registration is that copyright owners can file an infringement suit of works of u.s. origin in court. actually, filing a registration before or within five years of publishing a work will actually put the copyright owner in a stronger position in court to validate the copyright.18 additionally, copyright registration enables one to get awarded statutory damages and attorney’s fees and to gain protection against the importation of infringing copies.19 the emphasis on a free-to-use license along with the lack of clarification of the functions of copyright registration on the website of creative commons may not only mislead scholars to ignore important legal formalities within the copyright law, but also increase the abuse of original materials by stakeholders such as predatory publishers. one example is how the integrated study of marine mammals repackaged existing articles taking advantage of the creative commons licenses used by plos one, which has been publishing articles on digital humanities. 20 the oversimplified process of using cc licenses advocated by creative commons website may also prevent licensors from double-checking or clarifying if they have the legal right to license a work. in 2013, persephone magazine, which used an image with a creative commons license, was later sued for $1,500 for using it. it turned out the photo did not belong to the person who uploaded it with a cc license, which led to 73 companies who used it being sued. persephone magazine claimed that $1,500 was more than its entire advertising revenue for the year and it had to ask its users to donate just to keep the site going.21 therefore, scholars of digital humanities projects, which usually include different types of content such as artworks and photographs, should be wary of using cc licensed images. otherwise, a freely available license might end up costing a scholar unexpected money and energy. in the is creative commons a panacea for managing digital humanities ip rights? | ding 37 https://doi.org/10.6017/ital.v38i3.10714 meantime, when deciding to put their projects under cc licenses or to publish their works in a journal that requires cc licenses, scholars should also be reminded to make accurate and clear copyright statements to prevent innocent infringements of other copyright owners ’ works. for example, a team of art historians who create an online map of architectures in ancient china are very likely to use and critique other people’s images in digital projects under fair use. these digital humanists should cite image sources and clarify the scope of the cc license that they apply to their project. it is understandable that in order to promote an open, sharing culture, the application of a cc license is intentionally designed to be simple and free by creative commons to fulfill its mission. however, the misuse of a free license can lead to false licenses and more innocent infringements and ultimately costs. academic librarians should become aware of these pitfalls and provide more in-depth training on cc licenses to scholars, especially by collaborating with campus centers of digital humanities or language and literature faculty as well as other institutional research support departments as suggested by fraser and arnhem.22 is creative commons really safe?—the risk of irrevocability similar to the pitfall of inaccurate licenses, the irrevocability of cc licenses can also be problematic. a “revocable” license is one that can be terminated by the licensor at any time during the term of the license agreement. an “irrevocable” license, on the other hand, cannot be terminated if there is no breach. all cc licenses are irrevocable.23 licenses and contracts usually have effective date of termination and even if they don’t have one, most courts hold that simple, nonexclusive licenses with unspecified durations that are silent on revocability are revocable at will.24 as a result, the irrevocability of cc licenses can be easily overlooked by cc licensors. this means that while in traditional academic publishing and other means of the dissemination of research, scholarly, and creative output, a scholar will be able to revise the copyright agreement he or she has established with a publisher or a scholarly communication venue due to the usually clear rules on termination dates and revocability, it is impossible to revoke a cc license. this discrepancy of the revocability between traditional copyright agreements and cc licenses may put copyright owners at disadvantage especially because many of them apply noncommercial cc licenses. copyright experts have warned scholars to keep in mind that once a “nonexclusive license,” which cc noncommercial licenses are, has been chosen to grant one’s work, the scholar has lost potential opportunities to “license the same work on an exclusive basis,” which is the case in the commercialization of a digital humanities work.25 we can understand this pitfall of the irrevocability of cc licenses in a case in late 2014. a plan by yahoo to begin selling prints of images uploaded to flickr was met with anger by users, even though yahoo only used photos with creative commons licenses that explicitly allowed commercial uses. although yahoo’s use of cc licensed works was legal, users who initially applied cc licenses with commercial use would not have wanted the company making canvas prints from the photos they posted to flickr to make money.26 should these copyright owners understand better the irrevocability of cc licenses, they might have chosen a different type of cc license with caution. bill of rights, a community of people advocating for protecting the intellectual property rights of artists, even called this kind of commercial use “abuse.”27 although most digital scholars, like those flickr users, have a genuine interest in making their works available to as many people as possible, it can be hard to gauge their reactions to all unforeseen outcomes of applying cc licenses to their works. therefore, scholars need more institutional support and education to information technology and libraries | september 2019 38 become aware of the irrevocability of cc licenses when managing the intellectual property rights of their digital scholarship projects. this institutional awareness-building is especially important because of the lack of support from creative commons. irrevocability is listed in the “considerations before licensing” section on the website of creative commons. however, scholars may easily overlook the irrevocability feature of cc licenses due to two reasons. first, the 6,500-plus-word “considerations before licensing” section is not a mandatory step to go through for licensors. it is simply a clickable link from the “choose a license” webpage of creative commons.28 second, although every cc license consists of three layers, the lawyer-readable legal code, the human-readable deed, and the machine-readable code, the irrevocability of cc licenses can be easily buried in those texts when a layperson without any experience or training of cc license look for the simplest way to promote and expose their works as much as possible.29 some may suggest putting everything under noncommercial use. however, it is not an option for some platforms and is even discouraged by some digital scholarship repositories. for example, the open access scholarly publishers association strongly encourages the use of the cc-by license wherever possible.30 the rationale behind the recommendation is the hope to make scientific findings available for innovations as well as to make open-access journals sustainable with sufficient profit to operate. driven by the same objectives, cc-by has become the gold standard for oa publishing. the three largest oa publishers (biomed central, plos, and hindawi) all use this license.31 in particular, the often multimedia and viable characteristics of digital humanities projects can expose them to even more infringement issues in the future. one example of this is romelab, a project focusing on the recreation of the roman forum, and its website is made up of multiple separate components. the project’s website is constructed with the drupal content management system, and is integrated with a 3d virtual world component, where users can access the romelab website and walk through the virtual space of rome itself. romelab is currently under a creative commons attribution-noncommercial license. as a project funded by the mellon foundation, romelab is required to offer “nonexclusive, royalty-free, worldwide, perpetual, irrevocable license to distribute” its data. 32 however, it is never clear to the researchers creating the site how to release the data that only work within the proprietary software unity engine that they used to produce the virtual space and more importantly, all the 3d models and pictures. simply putting the whole site under the creative commons attribution-noncommercial license doesn’t automatically make its research data accessible by the public. in this case, the irrevocability of cc licenses further complicates the issue of cc licenses being oversimplified. specifically, since the romelab website is also equipped with a chat feature and a multiplayer function, allowing multiple users to interact with each other, the project has a great potential to make profit if repurposed as a teaching tool and even an educational game in the future. whether or not researchers of romelab manage to make their research data publicly available, cc licenses are not a panacea to handle conflicting data release expectations and intellectual property rights of unity engine and mellon foundation. it is therefore recommended that digital scholars consider various data types and licensing options before exclusively applying irrevocable cc licenses to their creative works. moreover, if the creator of romelab wants to produce a virtual introduction of the 3d world of the project, he should take into consideration of the limitation of cc licenses before disseminating his is creative commons a panacea for managing digital humanities ip rights? | ding 39 https://doi.org/10.6017/ital.v38i3.10714 work via platforms such as youtube. in 2014, a user found out that somebody took his drone video of burning man 2013 and reposted it in its entirety to youtube under the inaccurate and misleading title “drone’s eye view of burning man 2014,” which earned a large number of views and advertising.33 when everyone was looking for the newest drone video of burning man in 2014, the video posted by this other person received millions of views, which earned them money from youtube advertising. the reason the user cannot sue this other person is that he originally licensed his video under cc by license, which allows commercial use, and which unfortunately is youtube’s only cc license option.34 had the original videographer better understood the irrevocability of cc licenses, he might have chosen a different platform to disseminate his video or at least utilized other ways to protect his copyright. scholars would not want this kind of abuse of their original works and thus should be more cautious of the irrevocability of cc licenses. furthermore, youtube and many other platforms that digital humanities scholars use to disseminate their research, scholarly, and creative work fail to provide effective functionalities and incentives to fulfill cc’s attribution requirement.35 cc by license stipulates, “if supplied, you must provide the name of the creator and attribution parties, a copyright notice, a license notice, a disclaimer notice, and a link to the material.”36 to find this piece of information on youtube, however, someone must go to a video’s landing page and first click the “show more” text in the description below the video. although it is clear to see the cc attribution license with link displayed, someone must click a “view attributions” link to discover the original author’s credit and source video link. the difficulty of going through different steps may impede an average youtube user or most potential licensees of a cc-licensed digital scholarly work to learn the original creator of any content and if what they are viewing was partially or wholly created by someone else.37 since cc licenses only provide licensees with a very general requirement to attribute, licensees are allowed to attribute “in any reasonable manner.”38 with the only limitation to be “not in any way that suggests the licensor endorses you or your use,” licensees are not incentivized to accurately attribute to the scholar of the original work and thus to help disseminate his or her work crediting the copyright owner.39 while users can search for registered works on the official website of united states copyright office, there is no way to conduct a comprehensive search for works under cc licenses. creative commons does not maintain a database of works distributed under cc licenses. although there are search engines and websites for works under cc licenses, there is no way to conduct an exhaustive search.40 this can create hurdles for future licensees of a derivative work to accurately and clearly attribute the original work. one of the most important motivations of scholars to distribute their works under cc licenses is to get gain more exposure. due to all these above limitations and others to be discussed in this paper, scholars should be more cautious of the irrevocability of cc licenses and its lack of enforcement and support system to help licensors accurately attribute the original work. is creative commons really clear?—the ambiguity of noncommercial and nonderivative licenses noncommercial license in the legal code of a cc attribution-noncommercial-sharealike license, noncommercial is defined as “not primarily intended for or directed towards commercial advantage or monetary compensation. for purposes of this public license, the exchange of the licensed material for other material subject to copyright and similar rights by digital file-sharing or similar means is noncommercial provided there is no payment of monetary compensation in connection with the https://www.youtube.com/watch?v=m2thtb6iffa https://www.youtube.com/watch?v=m2thtb6iffa https://www.youtube.com/watch?v=z9jtiouk_6o https://creativecommons.org/licenses/by/2.0/ information technology and libraries | september 2019 40 exchange.”41 this seemingly clear statement can create some confusion and problems in the real world. while a commercial use weighs against fair use, copyright law does not rule infringement solely on a use being commercial. in fact, it is hard to determine a use as totally noncommercial. in the case of princeton university press v. michigan document services, inc., michigan document services (mds) being a commercial copy shop weighs against a finding of fair use, but mds’s use being commercial is only one of the four factors in a fair-use analysis. in this case, the court held that mds’s commercial exploitation of the copyrighted works from princeton university press did not constitute fair use although the courts clarified the educational use was “noncommercial in nature.”42 there have been a number of cases in us copyright law where commercial uses have been ruled lawful fair use. by making commercial use a decisive factor to determine an illegal use, creative commons fails to specify real cases of commercial uses and thus oversimplifies the complicated copyright issues involving commercial uses that scholars should be aware of. more specifically, many digital scholars nowadays post their articles and projects with noncommercially cc licensed images on a website, the maintenance of which is seldom free. similar to the case of princeton university press v. michigan document services, inc., the educational or scholarly use of those noncommercially licensed images should be considered “noncommercial in nature.”43 however, if a digital humanist maintains a website that is subsidized partly by google ads or a company, the nature of the use of those noncommercially licensed images might be called into question as in the case of princeton university press v. michigan document services, inc. although in both situations, the image is not “primarily intended for or directed towards commercial advantage or monetary compensation,” the digital humanist may still increase the traffic of his site and thus profit from including those images on his site. 44 the “different viewpoints and colliding interests” among commercial publishers, librarians, scholars, university administrators, and others may further complicate the already “ambiguous commercial nature of use” in fair use analysis that creative commons oversimplifies.45 the more recent case of great minds v. fedex office & print services, inc. demonstrates this ambiguity of commercial use and one use of cc noncommercial license that is legal yet unexpected and unwanted by copyright owners. to specify, great minds argued that fedex should compensate it for the money the company made from copying materials that great minds distributed under a cc attribution-noncommercial-sharealike 4.0 license. in an amicus brief to support fedex office, creative commons held that “entities using cc-licensed works must be free to act as entities do—including through employees and the contractors they engage in their service” and otherwise “the value of the license would be significantly diminished.”46 creative commons demonstrated its interpretation of a commercial use to be different from the ruling in the case princeton university press v. michigan document services, in which the judge explicitly ruled the use to be commercial because the copyright complaint was performed on “a profitmaking basis by a commercial enterprise” and clearly forbade the contract between this enterprise and a nonprofit organization to copy and distribute copyrighted content.47 in contrast, in the case of great minds v. fedex office & print services, inc., the court held that great minds ’ nonexclusive public license, i.e. cc attribution-noncommercial-sharealike 4.0 international public license, “unambiguously permitted school districts to engage fedex, for a fee, to reproduce” the copyrighted content.48 scholars should therefore be wary of the complicated process and “several areas of uncertainty” surrounding creative commons, which can be easily is creative commons a panacea for managing digital humanities ip rights? | ding 41 https://doi.org/10.6017/ital.v38i3.10714 overlooked when applying the “simple and easy” cc licenses.49 none of the interpretations of noncommercial uses by creative commons are specified in the generic license deed. compared to more customized licenses that usually involve direct interactions between the licensor and the licensee, the free-of-charge license, cc licenses, has a long way to go to protect both licensors and licensees from infringements and financial loss. a study of noncommercial uses conducted by creative commons indicates that noncommercial licenses account for “approximately two-thirds of all creative commons licenses associated with works available on the internet.”50 kim confirmed this popularity of cc noncommercial licenses that “over 60 percent flickr users prohibit commercial use or derivative work.”51 as kim elaborated and as the previous section in this paper on the irrevocability of cc licenses showcases, either commercial or noncommercial cc licenses are “likely to be detrimental to potential professional careers” of copyright owners.52 nevertheless, as stated by creative commons, they do not offer legal advice. 53 when providing copyright education, academic librarians should therefore remind digital scholars to be careful in using both commercial and noncommercial content and making their own content available for noncommercial purposes. nonderivative license similarly, scholars should be reminded to have a critical view of nonderivative use of cc licenses. according to title 17 section 101 of the copyright act, a “derivative work” is a work based upon one or more preexisting works in which it may be recast, transformed, or adapted.54 however, creative commons used the phrase “adapted material” to define derivative work in the legal code for nonderivative uses.55 creative commons has a different understanding of derivative works from what is defined by the copyright act in musical works. “adapted material is always produced where the licensed material is synched in timed relation with a moving image.”56 this means that while using an original soundtrack in a video is not derivative work according to the copyright act, videos that use an nd-licensed song violate the terms of the cc license. similar to the difference of revocability and commercial use between creative commons and copyright act as discussed earlier in this article, this different understanding of derivative work should be made aware to scholars. specifically, when providing copyright education to scholars, academic librarians should make it clear that nonderivative license cannot alienate the fair use rights of users and that a noncommercial nonderivative license does not prevent companies from using a work in a parody.57 some licensors of cc licenses may not share creative commons’ vision of an open, sharing culture as suggested by the prevalence of nd licenses.58 therefore, instead of providing generic recommendation on using cc licenses, academic librarians should “balance the interests of information users and rights holders” by providing a more sophisticated and critical perspective when educating the scholarly community about the nonderivative cc licenses.59 is creative commons really sustainable—the dilemma of sharealike and open access incompatible sharealike licenses for many digital scholars, the sharealike term in cc licenses is intended to distribute their works more broadly and openly since a licensee is required by creative commons to “distribute . . . [their contributions] . . . under the same license as the original.”60 nevertheless, some incompatibility issues arise to prevent a more open distribution of works. for example, since the creative commons system offers two different sharealike licenses, a scholar cannot create a new derivative work combining two sharealike works with different terms of their respective licenses. http://www4.law.cornell.edu/uscode/17/101.html information technology and libraries | september 2019 42 it is the open and accessible nature of cc-licensed works that makes them ideal for scholars including digital humanists to collaborate on projects but ironically, the sharealike function can create the risk of “an intractable thicket” if incompatibilities between those licenses hinder future collaboration.61 creative commons does provide a series of compatible licenses, but only same licenses with differences in cc versions are considered compatible.62 against open access? these incompatibilities between certain cc licenses have been pointed out by copyright experts to limit “the future production and distribution of creative works” and even “anti-public domain.”63 in 2009, the cofounder and ceo of creative commons, lawrence lessig, pointed out the perils of openness in government in his article “against transparency.”64 echoing his argument that “whether and how new information is used to further public objectives depends upon its incorporation into complex chains of comprehension, action, and response,” this paper advocates a critical perspective of cc licenses in digital scholarship. apart from all the limitations of cc licenses discussed already, a more unsettling misuse of cc licenses is a failure to recognize other rights of a work beyond copyright. in 2011, the image of an underage girl, which was placed on flickr under a cc license, was used in an advertising campaign for mobile phone services.65 although after the lawsuit, creative commons ceo added a term in the legal deed of the latest version (4.0) of every cc license to explicitly state that other rights such as publicity, privacy, or moral rights may limit how to use the material, the case reveals the perils of openness.66 when providing copyright education, academic librarians should not only warn digital scholars of this limitation of cc licenses but also encourage them to include a statement of intellectual property rights including privacy and other rights on their digital scholarship websites to reduce abuses and innocent infringements. conclusion even though cc licenses are helpful for digital humanities to gain more exposure, these licenses are still being improved. creative commons pledged to the community to “clarify how the nc limitation works in the practical world.”67 yet, when providing copyright consultation or partnering with digital humanity scholars, academic librarians should warn these scholars as both licensors and licensees the sophisticated implications of not only the noncommercial license, but also other characteristics and limitations of cc licenses. academic librarians should introduce to digital scholars a more critical view of cc licenses by collaborating with different campus stakeholders.68 while it is recommended that academic librarians suggest digital scholars place their creative works under noncommercial license, academic librarians should also educate them about the ambiguous definitions of commercial use as well as the possibility of commercial parody and other fair use situations. it is also recommended that academic librarians provide digital humanists with guidance on how to create intellectual property statements on their website, which should include not only copyright, but also privacy and other intellectual property rights. currently, a number of university libraries and nonprofit organizations, ranging from duke university library (http://library.duke.edu/), to library of congress (https://www.flickr.com/photos/library_of_congress), and wikipedia (https://en.wikipedia.org/wiki/main_page), use cc licenses for their entire site.69 as cc license http://library.duke.edu/ https://www.flickr.com/photos/library_of_congress https://en.wikipedia.org/wiki/main_page is creative commons a panacea for managing digital humanities ip rights? | ding 43 https://doi.org/10.6017/ital.v38i3.10714 users, academic librarians should also be extremely careful when using cc-licensed pictures or music on the library’s website. the safest way is to only use ones that are in the public domain or that are acquired by the library. despite the use of free and simple cc licenses, academic libraries are recommended to include terms of use and privacy sections on their websites to provide more detailed explanations of the function of cc licenses and intellectual property rights in general. the alignment between the visions of creative commons, digital humanities, and “higher education as a cultural and knowledge commons” put academic librarians in a unique position to provide copyright education in the digital humanities field.70 because of all the limitations of cc licenses, academic librarians should go beyond a simple endorsement of cc licenses and offer a more sophisticated and critical perspective when educating the scholarly community about cc licenses. notes 1 amanda hornby and leslie bussert, "digital scholarship and scholarly communication," university of washington libraries, accessed november 30, 2016,

public libraries are becoming e-government access points relied on by both patrons and government agencies, it is important for libraries to consider the implications of these roles. while providing e-government access serves to reinforce the tremendously important role of public libraries in the united states social infrastructure, it also creates new demands on libraries and opens up significant new opportunities. drawing upon several different strands of research, this paper examines the nexus of public libraries, values, trust, and e-government, focusing on the ways in which the values of librarianship and the trust that communities place in their public libraries reinforce the role of public libraries in the provision of e-government. the unique values embraced by public libraries have not only shaped the missions of libraries, they have influenced popular opinion surrounding public libraries and fostered the confidence that communities place in them as a source of trusted information and assistance in finding information. as public libraries have embraced the provision of internet access, these values and trust have become intertwined with their new social role as a public access point for e-government both in normal information activities and in the most extreme circumstances. this paper explores the intersections of these issues and the relation of the vital e-government role of public libraries to library funding, public policy, library and information science education, and research initiatives. p ublic libraries have always been valued and trusted institutions within society. due to recent advances in technology and changes in united states society, public libraries now also play a unique and critical role by offering free public internet access. with the increas­ ing reliance on the internet as a key source of news, social capital, and access to government services and information, the free access provided by public librar­ ies is an invaluable resource. as a result, a significant proportion of the u.s. population, including people who have no other means of access, people who need help using computers and the internet, and people who have lower quality access, rely on the internet access and computer help available in public libraries. federal, state, and local government agencies now also rely on public libraries to provide citizens with access to and guidance in using e­government web sites, forms, and services; many government agencies simply direct citizens to the nearest public library for help. this confluence of events has created a major new social role for public libraries— guarantors of internet and e­government access. though public libraries are not the only points of free internet access in many communities, they have created the strongest commitment to providing access and help for all. by providing not only the access to technology, but also to help using the technology, libraries became internet access points, while community technology cen­ ters, which usually did not offer the same level of avail­ able assistance, failed in the late 1990s and early 2000s. further, as libraries not only provide internet access, but free computer access as well, they attract the people who do not own computers and do not benefit from a city’s or coffee shop’s free wi­fi. the compelling combination of free computer access, free internet access, the avail­ ability of assistance from knowledgeable librarians, the value that public librarians place on serving their local communities, and the historical trust that society places in public libraries has made libraries a critical part of the u.s. social infrastructure. without public libraries, large segments of the population would be cut off from access to the internet and e­government. while the provision of internet access for those who have no other access parallels the role of public libraries as providers of access to print materials, the matura­ tion of public libraries into internet and e­government access hubs has profound implications for the roles that public libraries are being expected to play in their communities. public libraries are trusted by their com­ munities as places that community members can turn to for unfettered information access and as places to go for information in times of need. combining this trust with the power of internet access and support makes public libraries even more critical within their local com­ munities. the trust placed in libraries is also important in balancing the lack of confidence that many citizens place in other government institutions as well as in the internet. clearly, e­government, which exists at this intersection, has its trustworthiness bolstered by the role of public libraries in its use. as patrons are able to access e­government through the library—a place that is trusted—they may have greater confidence in the gov­ ernment services they use through library computers and with the assistance of librarians. the important role of libraries in providing citizens with access to the internet, and especially to e­govern­ paul

fleischmann public libraries, values, trust, and e-government article title | author 35public libraries, values, trust, and e-government | jaeger and fleischmann 35 ment, makes natural sense given the values of the public library. these new services reflect the values traditionally upheld by public libraries, such as equal access to infor­ mation, literacy and learning, and democracy. indeed, these values likely have played a significant role in developing and sustaining public trust in public libraries as institutions. thus, to understand how public libraries have come to serve as the default site for e­government access, it is important to consider how this role builds on and reflects the public library’s enduring values. drawing upon several different strands of research, this article explores the intersections of public libraries, values, trust, and e­government. the article first exam­ ines the values of public libraries and the role that these values play in influencing popular opinion surrounding public libraries. next, the article focuses on the trust that communities place in public libraries, which builds upon the values that libraries uphold. after that, the article explores the reasons why public libraries became and remain the public access point for e­government, providing examples from the 2004 and 2005 hurricane seasons that illustrate this point in the most extreme cir­ cumstances. the article then examines the nexus of public libraries, values, trust, and e­government, further exam­ ining how the values of librarianship and the confidence that communities place in their public libraries reinforce the role of public libraries in the provision of e­govern­ ment. finally, the article explores how the e­government role of public libraries could be cultivated to improve library services through involvement in research and educational initiatives. ■ public libraries and values values can be seen as “evaluative beliefs that synthesize affective and cognitive elements to orient people to the world in which they live.”1 in other words, values tie together how individuals think about the world and how they feel about the world. following this definition, values are situated within individuals. although they are a result of social interaction and may be shared among individuals, values are a highly individualized and per­ sonalized phenomenon. thus, values arise at the intersec­ tion of the individual and the social, with some scholars now making a case for increasing the emphasis placed on values in the social sciences.2 recently, many scholars and commentators have focused on the values of librar­ ies, most notably former ala president michael gorman, who has written extensively on the topic.3 gorman focuses on library values in response to what he views as a disconnect between library practitioners and academics. he argues that library­science programs are becoming increasingly detached from reality, and that one way to ground library science, as well as the library profession, is through an emphasis on the values of librar­ ianship, which demonstrate the core, enduring values of the profession.4 he explains that values, on the one hand, should provide a foundation for interaction and mutual understanding among members of a profession; on the other hand, they should not be viewed as immutable, but rather as sufficiently flexible to match the changing times. he lists eight central values of librarianship that he views as particularly salient at present: stewardship, service, intellectual freedom, rationalism, literacy and learning, equity of access to recorded knowledge and information, privacy, and democracy. frances groen echoes gorman’s sentiments and argues that one of the major limitations of library­science programs is their lack of attention to values.5 she argues that library and information science (lis) programs place almost all of their educational emphasis on what librar­ ians do and how they do it, and almost none on the rea­ sons why they do what they do and why such activities are important. she identifies three fundamental library values: access to information, universal literacy, and preservation of cultural heritage, all of which she argues are also characteristics of liberal democratic societies. this argument parallels the observation that increases in information access within a society are essential to increasing the inclusiveness of the democratic process in that society.6 library historian toni samek focuses on another aspect of library values that is no longer as strongly emphasized—attempts to achieve neutrality in libraries.7 neutrality often was advocated as a cherished value, in the sense of providing equal access to all information and sources. however, samek demonstrates that libraries, on the contrary, were more likely to emphasize mainstream information sources and thus privilege them over alter­ native sources. not only has the value of neutrality been problematic in terms of how it has been implemented and mobilized in public libraries in the 1960s and 1970s, but it also is perhaps impossible to ever achieve in reality.8 the fact that neither gorman nor groen include neutrality in their listings of fundamental library values demonstrates how library values have continued to evolve as public libraries have developed as social institutions. as library values have developed, they have served to unite librarians and establish the role of public libraries in their communities. the values of librarianship have been encoded in the american library association’s (ala) library bill of rights, which strongly asserts the values of equal access and service for all patrons, nondiscrimina­ tion, diversity of viewpoint, and resistance to censorship and other abridgments of freedom of expression.9 the values of libraries and librarianship are one of the fac­ tors that lead communities to trust public libraries, as the following section explores. overall, further study of the 36 information technology and libraries | december 200736 information technology and libraries | december 2007 role of values in libraries is essential, especially given the increasing role of technology in public libraries.10 ■ public libraries and trust exactly one half of the respondents to a 2007 pew research center study agreed with the statement “you can’t be too careful in dealing with people.”11 however, even in a climate where trust can be a precious commodity, public libraries are trusted by their communities. carr argues that libraries have come to earn the trust of their com­ munities because of four obligations that librarians strive to meet: to provide user­centered service, to actively engage in helping users, to connect information seekers to unexplored information sources, and to take the goal of helping users as a professional duty that is controlled first and foremost by the library user.12 similarly, jaeger and burnett argue that, because of its traditional defense of commonly accepted and popular values—such as free access to and exchange of information, providing a diverse range of materials and perspectives to users from across society, and opposition to government intrusions into personal reading habits—public libraries have come to be seen by members of the populace as a trusted source of information in the community.13 gorman argues for a direct link between the values of libraries and the trust that is instilled within them by the public, stating that one important mission for ensuring the survival of libraries and librarianship is “assuring the bond of trust between the library and the society we serve by demonstrating our stewardship and commitment, thus strengthening the mutuality of the interests of librar­ ians and the broader community.”14 further, a 2006 study conducted by public agenda found that “public libraries seem almost immune to the distrust that is associated with so many other institutions.”15 in specific terms of the internet, the public library “is a trusted community­based entity to which individuals turn for help in their online activities—even if they have comput­ ers and internet access at home or elsewhere.”16 in a large­ scale national survey, 64 percent of respondents, including both users and non­users of public libraries, asserted that providing public access to the internet should be one of the highest priorities for public libraries.17 thus, trust in public libraries seems to carry over from other library services to provision of internet access and training. however, challenges to trust in public libraries seem to be growing in the internet age. the trusted role of pro­ tecting users’ personal information may create conflicts with the other social responsibilities of public libraries.18 as a result of a lack of preparedness of some librarians to deal with privacy issues, it is possible that “the trust that research shows users place in libraries is not fully repaid.”19 a 2005 oclc study suggests that, indeed, user trust in public libraries shows signs of weakening, as the majority of citizens place as much trust in internet search engines as they do in public libraries.20 further, the changes in the law following the 9/11 terror attacks that have increased the ability of the federal government to track patron activities in public libraries, such as through the usa patriot act, have raised serious concerns about privacy and freedom of expression among many public library patrons and librarians.21 trust in libraries also has been challenged by the impo­ sition of filters for public libraries that receive e­rate fund­ ing due to the children’s internet protection act.22 while internet access is no longer unfettered in libraries that have to comply with the law, public libraries have been able to prevent this law from eroding their role as trusted internet provider through ala’s vigorous legal challenge to the constitutionality of law and the rejection of e­rate funds by a large number of libraries after the supreme court upheld the constitutionality of the law.23 thus, the trusting rela­ tionships that public libraries have built with their com­ munities are valuable commodities that can be transferred under some circumstances from one particular service to another, yet are not inalienable rights granted to public libraries. rather, public trust is something that libraries must work hard to maintain. trust in public libraries also has served as an important cause and effect of the role of libraries in providing access to e­government. ■ public libraries and e-government public libraries are not only trusted as a means of access to the internet in general, they are trusted as a provider of access to e­government. with nearly every united states public library now connected to the internet and offer­ ing free public access, they can fill a community need of ensuring that all citizens have access to e­government and assistance using e­government services.24 indeed, public libraries and the internet have both improved public access to government information.25 this social role also is embraced by all levels of government, with government agencies often directing people with questions about their online materials to public libraries for help.26 as such, government agencies also trust public libraries to serve as key providers of e­ government access and training. public libraries could not have foreseen becoming the default social access point for e­government when they began to provide free public internet access in the mid­1990s, due in great part to the largely separate evolution of internet access in libraries and e­government. however, they now fill this role in society, ensuring access to those who have no other means of reaching e­government and providing a safety article title | author 37public libraries, values, trust, and e-government | jaeger and fleischmann 37 net of training and assistance for those who have access but need help using e­government. public libraries have developed into the social source of e­government for two reasons. the first is simply that libraries committed to the provision of public internet access in the early 1990s and have continued to grow and improve that access so that virtually all public libraries in the united states provide free public internet access.27 however, presence of access alone does not account for the current role of the public library, as most public schools and government offices have internet access, and community technology centers were origi­ nally funded to create an environment that would provide computer access. a key difference in public libraries is that they are historically trusted as providers of information, including government information, to all segments of society. “the public library is one place that is culturally ingrained as a trusted source of free and open information access and exchange.”28 a key part of the provision of internet access in pub­ lic libraries also has been providing help. as heanue explains, “even if americans had all the hardware they needed to access every bit of government information they required, many would still need the help of skilled librarians whose job it is to be familiar with multiple systems of access to government systems.”29 not only is the information trusted because of the source, the help is trusted because the librarians are part of the library. as e­government has developed and the complexity has grown, this trusted help has become invaluable to many people who need to use e­government but do not feel able to on their own. in a 2001 study of both public library and internet users, the key preferences identified for public libraries included the ease of use, accuracy of informa­ tion available, and help provided by library staff.30 these perceptions have carried over into e­government, as the staff members not only provide help using e­government; their guidance directs users to the correct e­government sites and forms and makes using the sites an easier expe­ rience than it otherwise would be. in the era of e­government, governments internation­ ally are showing a strong preference for delivering ser­ vices via the internet, particularly as a means of boosting cost­efficiency and reducing time spent on direct interac­ tions with citizens.31 however, citizens show a strong preference for phone­based or in­person interactions with government representatives when they have questions or are seeking services.32 e­government services generally are limited by difficulties in searching for and locating the desired information, as well as lack of availability of computers and internet access to many segments of the general population.33 such problems are exacerbated by general lack of familiarity of the structure of government and which agencies to contact as well as many citizens’ attitudes toward technology and government.34 also, as e­government sites give more emphasis to presenting political agendas rather than promoting democratic par­ ticipation, users are less trusting of the sites themselves.35 finally, perhaps the most compelling reason for the reli­ ance on public libraries to provide access to and help with e­government is that public libraries provide support equally to all members of a community—and that free services are of most relative value to those who have the fewest resources of their own. as a result of the reliance of patrons and government agencies on the public library as a center for e­government access and assistance, public librarians have had to become de facto experts on e­government, ranging from medicare prescription plans to fema forms to immigration registra­ tion to water management registration.36 in one case, the involvement of a librarian who specialized in government information was necessary in a community planning pro­ cess to sort through the related e­government materials and information sources.37 one area where the social roles as provider of e­government and as trusted provider of information were notably intertwined was during the 2004 and 2005 hurricane seasons along the gulf coast. ■ public libraries as trusted provider of e-government public libraries have become vital access points and com­ munication hubs for many communities and, in times of emergency, are vital in helping their communities cope with the crisis.38 this role proved especially important in com­ munities along the gulf coast during the unprecedented 2004 and 2005 hurricane seasons, with public libraries employing their internet access to assist their communities in hurricane recovery in numerous ways. the public librar­ ies in that region described five major roles for the public library internet access in communities after a hurricane: ■ finding and communicating with dispersed and dis­ placed family members and friends; ■ completing fema forms, which are online only, and insurance claims; ■ searching for news about conditions in the areas from which they had evacuated; ■ trying to find information about the condition of their homes or places of work, including checking news sites and satellite maps; and ■ helping emergency service providers find informa­ tion and connect to the internet.39 the provision of e­government information and assis­ tance in filling out e­government forms was a central function of these libraries in helping their communities. the level of assistance was astounding—one mississippi library completed more than forty­five thousand fema 38 information technology and libraries | december 200738 information technology and libraries | december 2007 applications for patrons in the first month after katrina struck—despite the fact that the libraries were not specifi­ cally prepared to offer such a service and that few library systems planned for this type of situation.40 furthermore, while libraries helped many communities, they could not meet the enormous needs in the affected communi­ ties. the events along the gulf coast in 2004 and 2005 revealed a serious need for the integration of local and state public entities that have large­scale coordination plans to work with the libraries.41 most of the functions that community organizations played in the most ravaged areas after katrina, rita, wilma, dennis, ivan, and the other major storms were completely ad hoc and unplanned.42 the federal gov­ ernment was of little help in the immediate aftermath of many of these situations.43 as such, it was the local community organizations, particularly public libraries, that used information technology (at least what was still working) to try to pick up the pieces, get aid, find the missing, and perform other vital functions. consider the following quotes from local government officials explaining the role computers and internet access in public libraries played in providing information to dev­ astated communities: our public access computers have been the only source of communicating with insurance carriers, the federal emergency management agency and other sources of aid. the greatest impact has been access to information such as fema forms and job applications that are only available via internet. this was highly visible during the aftermath of hurricanes rita & katrina. overall access to information in this rural community has been outstanding due to use of the internet. relief workers were encouraged to use the library to keep in touch with family and friends through email. . . . the library provided a fema team with local maps and help in locating areas that potentially suffered major damage from the storm. during the immediate aftermath of katrina, our com­ puters were invaluable in locating missing family, applying for fema relief (which could only be done online) and other emergency needs. for that time—the computers were a godsend. we have a large number of displaced people who are coming to rely upon the library in ways many of them never expected. i’ve had so many people tell me that they had never been to a library before they had to find someplace to file a fema application or insur­ ance claim. many of these people knew nothing about computers and would have been totally lost without the staff’s help.44 along with e­government access, one of the greatest affects of access to information related to searches for lost family, friends, and pets, with many libraries creating lists of individuals who had been to the library and who were being sought to help in establishing contacts between people. as one librarian stated, “our computers were invaluable in locating a missing family.”45 searches were conducted by patrons and by librarians helping them to locate evacuees and search for information about those who stayed behind. internet access also allowed patrons to have “contact with family members outside of the disaster area,” “communicate with family and friends,” and “stay in touch with family and friends due to lack of telephone service.”46 libraries used their internet access to aid rescue personnel to communicate with their agen­ cies, and even to direct emergency responders with direc­ tions, maps, and information about where people most needed help.47 the level of local libraries’ success in meeting the needs of their communities after the hurricanes varied widely, though. many were simply overwhelmed by the numbers of people in need and limited by the fact that they had never expected to have to act as a community lifeline in this way.48 the libraries that faired the best were usually in florida; they have a greater familiarity with dealing with hurricanes and thus were more prepared and had more established ties between local libraries, county governments, and state agencies.49 having internet access and expertise is clearly not enough. planning, coordina­ tion, experience, and government support and funding all influenced how different public libraries were able to respond after the major hurricanes. public libraries also may be able to play a role in ongoing emergency response efforts, such as the development of large­scale community response grids that coordinate citizens and emergency responders in emergencies.50 the greatest lesson, however, may be that public librar­ ies, as trusted providers of information technology access, particularly access to e­government, are the most local line of response in communities. the national government failed shatteringly and completely to help people after hurricane katrina, while little public libraries in and on the edges of the devastation hummed along. the local nature of the response that libraries could provide man­ aged to reach communities and members of those commu­ nities much better than national or state level responses. such local response to crises, while vital, is becoming much harder to find outside of public libraries. ■ the nexus of public libraries, values, trust, and e-government the democratically oriented core values of public librar­ ies and the trust that communities place in their public article title | author 39public libraries, values, trust, and e-government | jaeger and fleischmann 39 libraries have the potential to significantly enhance and strengthen the role of public libraries in the provision of e­government. citizens who access e­government using computers in public libraries, and with the expert assistance of librarians, may have more confidence in the e­government information and services they are using as a result of their high regard for public libraries. as patrons trust that librarians will help them reach the information they need, patrons’ awareness of and confidence in e­government will increase as they learn from librarians about the types of information and services available from e­government. further, by teaching patrons what is available from and how to use e­government, librar­ ians are serving to increase the number of e­government users. because e­government is still at an early stage in its development, such positive associations could play a critical role in encouraging and facilitating its widespread acceptance and adoption. just as e­government is still in its formative stages, research on e­government also is just getting started. to date, research on e­government has focused more on technical than social aspects. for example, a meta­ analysis of 110 peer­reviewed journal articles related to e­government revealed that the relationship between e­government and values is an important, yet to date understudied, topic.51 it is important to consider not only bandwidth and markup languages, but also values and trust in developing and analyzing e­government. it also is important to consider the relationship between trust in e­government and the potential for increasingly participatory democracy. trust can be seen as “centrally positioned at the nexus between the primarily internally driven administrative reforms of e­government’s architecture and the related, more exter­ nally rooted pressures for e­governance reflected in widening debates on openness and engagement.”52 similarly, “citizen engagement can help build and strengthen the trust relationship between governments and citizens.”53 through e­government, it is possible to facilitate citizen participation in government through the bidirectional interactive potential of the internet, making it possible to move toward strong democracy.54 greater faith in democracy can potentially significantly increase citizen trust in e­government. at the same time that we consider all of these impor­ tant issues related to e­government, it is important not to lose sight of the critical role that public libraries play in the provision of e­government. further, it is necessary to make certain that public libraries receive credit and support for the work that they do in providing access to and help with e­government. as demonstrated above, public libraries are uniquely and ideally situated to ensure access to and assistance in using e­government information and services. however, this activity is not sustainable without the recognition and resources that must accompany this role. the conclusion addresses this important point in more detail. ■ conclusions and future directions the evolution of the public library into an e­government access point has occurred without the direct intention of public libraries and without their involvement in policy decisions related to these new social roles. as with the need to become more active in encouraging the develop­ ment of technologies to help libraries fulfill these social expectations, public libraries also must become more involved in the policy­making process and in seeking financial and other support for these activities. public libraries have to demand a voice not only to better con­ vey their critical role in the provision e­government, but to help shape the direction of the policy­making process to ensure more government support for the access to and help with e­government that they provide. public libraries have taken on these responsibilities without receiving additional funding. while the provi­ sion of internet access alone is a major expense for public libraries, the reliance of government agencies on public libraries as the public support system for e­government adds very significant extra burdens to libraries.55 in a 2007 survey of florida public libraries, for example, 98.7 percent indicated that they receive no support from an outside agency to support the e­government services the library provides, despite the fact that 83.3 percent of responding libraries indicated that the use of e­govern­ ment in the library had increased overall library usage.56 this lack of outside support has resulted in public librar­ ies in different parts of the country having widely varying access to the internet.57 the reality is that public libraries are expected by patrons and government agencies to fulfill this social role, whether or not any support—financial, staffing, or training—is provided for this role. the vital roles that public libraries played in the aftermath of the major hur­ ricanes of the 2004 and 2005 seasons may have perma­ nently cemented the public and government perception of public libraries as hubs for e­government access.58 while public libraries have become the unofficial uni­ versal access point for e­government and are trusted to serve as a vital community response and recovery agency during emergencies, they do not receive funding or other forms of external assistance for these functions. public libraries need to become involved in and encourage plans and programs that will serve to sustain these essential and inextricably linked activities, while also bringing some level of financial, training, and staffing support for these roles. the tremendous efforts and successes of public librar­ ies in the aftermath of the 2004 and 2005 hurricanes has 40 information technology and libraries | december 200740 information technology and libraries | december 2007 earned libraries a central position to e­government and emergency planning at local, state, and federal levels. in those emergency situations, public libraries were able to serve their communities in a capacity that was far beyond the traditional image of the role of libraries, but these emergency response roles are as significant as anything else libraries could do for their communities. in order to continue fulfilling these roles and adequately performing other expected functions, public libraries need to push not only for financial support, but also for a greater role in planning and decision­making related to e­government services as well as emergency response and recovery at all levels of government. if strategic plans and library activities have a consis­ tent message about the need for support, the interrelated roles of trusted source of local information, e­government access provider, and community­response information and coordination center can make a compelling argument for increases in funding, support, and social standing of public libraries. the most obvious source of further sup­ port for these activities would be the federal government. amazingly, federal government support accounts for only about 1 percent of public library funding.59 given that federal government agencies are already relying on public libraries to ensure access to e­government and fos­ ter community response and recovery in times of emer­ gencies, federal support for these social roles of the public library clearly can and should be increased significantly. state libraries, cooperatives, and library networks already work to coordinate funding and activities related to certain programs, such as the e­rate program.60 these same library collectives may be able to work together to promote the need for additional resources and coor­ dinate those resources once they are attained. private and public partnerships offer another potential means of support for these library activities. with its strong historical and current connections to technology and libraries, the bill and melinda gates foundation might be a very important partner in funding and facilitating the increased role that public libraries play in providing access to and help with e­government. the search for additional funding to support e­government provision should not only focus on funds for access and training, but also on funds for research about how to better meet individual and community e­government needs and the affects of e­government provision by public libraries on individuals and communities. regardless of what approaches are taken to find­ ing greater support, however, public libraries must do a better job of communicating their involvement in the provision of e­government to governments and private organizations in order to increase support. such commu­ nications will need to be part of a larger strategy to define a place within public policy that gives public libraries a voice in e­government issues. if public libraries are going to fulfill this social role, they must become a greater pres­ ence in the national policy discourse surrounding e­gov­ ernment. to increase their support and standing in policy discourse, libraries must not be hesitant in reminding the public and government officials of their successes after emergencies and in providing the social infrastructure for e­filing of taxes, enrolling in medicare prescription drug plans, and myriad other routine e­government activities. in many societies, e­government has come to be seen by many citizens and governments as a force that will enhance democratic participation, more closely link citizens and their representatives, and help disadvan­ taged populations become more active participants in government and in society.61 e­government is seen by many as having “the potential to fundamentally change a whole array of public interactions with government.”62 while the e­government act of 2002 and president’s e­government management agenda have emphasized the transformative effect of e­government, thus far it has primarily been used as a way to make information available, provide forms and electronic filing, and distrib­ ute the viewpoints of government agencies.60 however, many citizens do look to e­government as a valuable source of information, considering e­government sites to be “objective authoritative sources.”64 currently, the primary reason that people use e­government is to gather information.65 in the united states, 58 percent of internet users in the united states believe e­government to be the best source for government information, 65 percent of americans expect that information they are seeking will be on a government site, and 26 million americans seek political information online everyday.66 public satisfaction with the e­government services available, however, is limited. as commercial sites are developing faster and provide more innovative services than e­government sites, public satisfaction with gov­ ernment web sites is declining.67 public confidence in government web sites also has declined as much of the public policy related to e­government since 9/11 has been to reduce access to information through e­govern­ ment.68 the types of information that have been affected include many forms of socially useful information, from scientific information to public safety information to information about government activities.69 for these and other reasons, the majority of citizens, even those with a high­speed internet connection at home, seeking govern­ ment information and services prefer to speak to a person directly in their contacts with the government.70 in many cases, people turn to public librarians to serve as the per­ son involved in e­government contacts. further, when people struggle with, become frustrated by, or reject e­government services, they turn to public libraries. every year, public libraries deal with huge num­ bers of patrons needing help with online taxes, and the medicare prescription drug plan sign­up period resulted in article title | author 41public libraries, values, trust, and e-government | jaeger and fleischmann 41 an influx of seniors to public libraries seeking help in using the online registration system.71 for example, during the 2006 tax season, virginia discontinued the distribution of free print copies of tax forms to encourage use of the online system. instead, citizens of the state flooded public librar­ ies, assuming that libraries could find them print copies of the forms, which of course the libraries did. it seems unlikely, however, that the same government officials pushing the use of e­government are aware of the roles of public libraries in helping citizens with day­to­day e­government use. further, the enormous social roles of public libraries in emergency response in communities, such as during the 2004 and 2005 hurricane seasons, are far from widely known among government officials. to encourage the provision of external funding, the develop­ ment of targeted support technologies, and policy sup­ port for these social roles, public libraries must make the government and the public better aware of these roles and what is needed to ensure that the roles can be fulfilled. similarly, there is an extremely important role for lis programs in ensuring public libraries can meet community expectations for e­government provision. lis program graduates need to be prepared to help patrons access and use e­government information and services. as govern­ ment activities move primarily or exclusively online, patrons will increasingly seek help with e­government from public libraries. lis programs must ensure that grad­ uates are ready to serve patrons in this capacity. in 2007, the college of information studies at the university of maryland became the first ala­accredited school to offer a concentration in e­government as part of the master of library science program.72 the goal of this concentration is to prepare future librarians who wish to specialize in e­government, which will be an area of increasing and sig­ nificant need as more government information and services move online and more government agencies rely on public libraries to ensure access to e­government. lis programs need to prioritize finding ways to incorporate the teaching of issues related to e­government in public libraries as new concentrations or courses, or into existing courses. the provision of e­government is an important role of public libraries that is likely to increase significantly, and gradu­ ates of lis programs need to be prepared to meet patrons’ e­government information needs. further, lis faculties also can support public libraries in their e­government access and training roles by focusing more research on the intersections of public libraries and e­government. ultimately, the role of the trusted and valued public provider of e­government access creates many financial and staffing obligations and social responsibilities, but it also is a tremendous opportunity for public libraries. fighting against censorship efforts in the 1950s estab­ lished the public perception of libraries as guardians of the first amendment during the mccarthy era.73 working to ensure access and the ability to use e­government is creating new public perceptions of libraries as guardians of equal access in new but just as socially meaningful ways. rather than needing to ponder whether the emer­ gence of the internet will limit or remove the relevance of public libraries, the advent of e­government has created a brand new and very significant role that public libraries can play in serving their communities. given the empha­ sis that governments are placing on moving information and services online, patrons will continue to need access to and assistance in using e­government. the trust and values that have long been associated with public libraries are evolving to include the social expectations of the provision of access to and training for e­government by public libraries. in the same ways that patrons have learned to trust public libraries to provide equal access to print information sources, they now have learned to trust that libraries can provide equal access to e­government information. it seems that citizens will regu­ larly be turning to public libraries for help with mundane e­government activities, such as finding forms and filing taxes, as well as with the most pressing e­government activities, as was demonstrated in the aftermath of hur­ ricanes katrina and rita. because the trust in and values of public libraries have set the stage for the emerging role of libraries in e­government, public libraries need to work to ensure the availability of the support, education, and policy decisions that they need to serve their communities in this new and vital role in situations ranging from every­ day information needs to the most extreme circumstances. in spite of the costs associated with serving as the public’s e­government access center, acting as the social guarantor of equal access to e­government emphatically demonstrates that public libraries will continue to be a central part of the infrastructure of society in the internet age. public libraries now must learn to articulate better the social roles they are playing and the types of support they need from lis programs, funding agencies, and gov­ ernment agencies to continue playing these roles. ■ acknowledgment the authors of this paper have worked with several col­

lita president’s message joining together emily morton-owens information technology and libraries | december 2019 2 emily morton-owens (egmowens.lita@gmail.com) is lita president 2019-20 and the assistant university librarian for digital library development & systems at the university of pennsylvania libraries. . in writing this column i am looking ahead, as i have been throughout my term as vice-president and president of lita, to the possibility of our merger with alcts and llama. recently our discussions have included an exploration on all sides of how a division can support members through their career. this has inspired me to reflect on how lita has always taken a broad and inclusive view of what library technology work is and can be in the future. i believe the proposed core division can support and extend that tradition. one question that i’ve heard posed from time to time is “am i technical enough for lita?” longtime lita members like to answer that with a full-throated “yes!” if you’re interested enough to ask the question, we want you to join us in using technology as a part of your work. we want you to be supported in doing so at your current skill level, whether or not you want to make technology more a part of your work than it is today. if you want to go deeper into technology, we’ll be there with you. while the culture of the for-profit technology industry can promote imposter syndrome, we want lita to be a haven. in lita’s events and meetings, we consistently see different facets of library technology work reflected. some of us are training users in new technologies or creating programs that get young people excited about coding. others are working to make online resources accessible and easy for our users to benefit from. we have members who are manipulating metadata, creating services to help researchers comply with data management requirements, creating websites that guide users to the information they need, and preserving cultural heritage in digital forms. some of us manage tech projects or workers. some of our members work on large tech teams with generous resources and others are spinning magic just from their own skills. when i started working in libraries, my bosses and mentors were often librarians who had started in technical services or other roles, before “automation.” eager to improve their own workflows, and getting pulled into ils migrations and catalog development, they had become the technology experts. these accidental systems librarians have always been some of my favorite colleagues because of their sure-footed approach to our data. recently i’ve come to work with colleagues who are accidental systems librarians in the opposite sense; tech workers who took jobs in libraries and embraced what we do. one developer on my team, who had no previous library experience, took to our projects and ethical stance like a duck to water. he told me that he now goes to parties and tells people about how librarians are defenders of privacy and protectors of information. lita embraces growth in any direction because we want to support learning and problem-solving with a foundation of shared principles and resources. i don’t see these developments as time-based or inevitable in any given person’s career. there are plenty of library tech workers who prefer being an individual contributor and think they have mailto:egmowens.lita@gmail.com joining together | morton-owens 3 https://doi.org/10.6017/ital.v38i4.11905 their biggest impact doing direct work on applications. and many of my technical services colleagues prefer to define their work goals in those terms, no matter how adept they become with tech tools. whether or not they seek out a management position, our members will probably find themselves exhibiting leadership in some context, like developing standards or advocating for standards. instead of a rigid path of career development, many librarians today have fluid and multi-faceted careers. for myself, i have held similar positions at quite different types of libraries—public, medical, academic. lita has always been a part of my experience, though, providing a sort of collegial bedrock through a lot of change. the people are what make lita, lita: friendly, principled, and quirky. lita members are the kind of people who will learn all they can about a technology like the amazon alexa—and then unplug the one on the exhibit floor at annual. both as i was thinking about all this, and in this resulting column, leadership, collections, and technical services kept coming up. there is such strong and fruitful cross-pollination among these specialties, and i see that as something that would enhance the member experience—both for current lita members who want more contact with expert colleagues and for current llama and alcts members who want learning opportunities and support for their work with technology. lita members love to share their knowledge and hash through challenges together. sometimes i wish more ala members would feel comfortable giving us a try, and perhaps core will be a new, friendly face for that ongoing outreach. if, in the future, someone asked the new question “am i technical enough for core?” i’m sure the answer will be the same: “yes, please join us!” articles no need to ask: creating permissionless blockchains of metadata records dejah rubel information technology and libraries | june 2019 1 dejah rubel (rubeld@ferris.edu) is metadata and electronic resource management librarian, ferris state university. abstract this article will describe how permissionless metadata blockchains could be created to overcome two significant limitations in current cataloging practices: centralization and a lack of traceability. the process would start by creating public and private keys, which could be managed using digital wallet software. after creating a genesis block, nodes would submit either a new record or modifications to a single record for validation. validation would rely on a federated byzantine agreement consensus algorithm because it offers the most flexibility for institutions to select authoritative peers. only the top tier nodes would be required to store a copy of the entire blockchain thereby allowing other institutions to decide whether they prefer to use the abridged version or the full version. introduction several libraries and library vendors are investigating how blockchain could improve activities such as scholarly publishing, content dissemination, and copyright enforcement. a few organizations, such as katalysis, are creating prototypes or alpha versions of blockchain platforms and products.1 although there has been some discussion about using blockchains for metadata creation and management, only one company appears to be designing such a product. therefore, this article will describe how permissionless blockchains of metadata records could be created, managed, and stored to overcome current challenges with metadata creation and management. limitations of current practices metadata standards, processes, and systems are changing to meet twenty-first century information needs and expectations. there are two significant limitations, however, to our current metadata creation and modification practices that have not been addressed: centralization and traceability. although there are other sources for metadata records, including the open library project, the largest and most comprehensive database with over 423 million records is provided by the online computer library center (oclc).2 oclc has developed into a highly centralized operation that requires member fees to maintain its infrastructure. oclc also restricts some members from editing records contributed by other members. one example of these restrictions is the program for cooperative cataloging (pcc). although there is no membership fee for pcc, catalogers from participating libraries must receive additional training to ensure that their institution contributes high quality records.3 requiring such training, however, limits opportunities for participation and can create bottlenecks when non-pcc institutions identify errors in a pcc record. decentralization no need to ask | rubel 2 https://doi.org/10.6017/ital.v38i2.10822 would help smaller, less-well-funded institutions overcome such barriers to creating and contributing their records and modifications to a central database. the other significant limitation to our current cataloging practices is the lack of traceability for metadata changes. oclc tracks record creation and changes by adding an institution’s oclc symbol to the 040 marc field.4 however, this symbol only indicates which institution created or edited the record, not what specific changes they made. oclc also records a creation date and a replacement date in each record, but a record may acquire multiple edits between those two dates. recording the details of each change within a record would help future metadata editors to understand who made certain changes and possibly why they were made. capturing these details would also mitigate concerns about the potential for metadata deletion because every datum would still be recorded even if it is no longer part of the active record. information science blockchain research many researchers and institutions are exploring blockchain for information science applications. most of these applications can be categorized as either scholarly publishing, content dissemination and management, or metadata creation and management. one of the most promising applications for blockchain is coordinating, endorsing, and incentivizing research and scholarly publishing activities. in “blockchain for research,” rossum from digital science describes benefits such as data colocation, community self-correction, failure analysis, and fraud prevention.5 research activity support and endorsement would use an academic endorsement points (aep) currency to support work at any level, such as blog posts, data sets, peer reviews, etc. the amount credited to each scientist is based on the aep received for their previous work. therefore, highly endorsed researchers will have a greater impact on the community. one benefit of this system is that such endorsements would accrue faster than traditional citation metrics.6 one detriment to this system is its reliance on the opinions of more experienced scientists. the current peer review process assumes these experts would be the best to evaluate new research because they have the most knowledge. breakthroughs often overturn the status quo, however, and consequently may be overlooked in an echo chamber of approved theories and approaches. micropayments using aep could “also introduce a monetary reward scheme to researchers themselves,” bypassing traditional publishers.7 unfortunately, such rewards could become incentives to propagate unscientific or immoral research on topics like eugenics. in addition, research rewards might increase the influence of private parties or corporations to science and society’s detriment. blockchains might also reduce financial waste by “incentivizing research collaboration while discouraging solitary and siloed research.”8 smart contracts could also be enabled that automatically publish any article, fund research, or distribute micropayments based on the amount of endorsement points.9 to support these goals, digital science is working with katalysis on the blockchain for peer review project. it is hard to tell exactly where they are in development, but as of this writing, it is probably between the pilot phase and the minimum viable product.10 the decentralized research platform (deip) serves as another attempt “to create an ecosystem for research and scientific activities where the value of each research…will be assessed by an experts’ community.”11 the whitepaper authors note that the lack of negative findings and unmediated or open access to information technology and libraries | june 2019 3 research results and data often leads to scientists replicating the same research.12 they also state that 80 percent of publishers’ proceeds are from university libraries, which spend up to 65 percent of their entire budget on journal and database subscriptions.13 this financial waste is surprising because universities are the primary source of published research. therefore, deip’s goals include research and resource distribution, expertise recognition, transparent grant processes, skill or knowledge tracking, preventing piracy, and ensuring publication regardless of the results.14 the second most propitious application of blockchain to information science is content dissemination and management.15 blockchain is an excellent way to track copyright. several blockchains have already been developed for photographers, artists, and musicians. examples include photochain, copytrack, binded, and dotbc.16 micropayments for content supports the implementation of different access models, which can provide an alternative to subscriptionbased models.17 micropayments can also provide an affordable infrastructure for many content types and royalty payment structures. blockchain could also authenticate primary sources and trace their provenance over time. this authentication would not only support archives, museums, and special collections, but it would also ensure law libraries can identify the most recent version of a law.18 finally, blockchain could protect digital first sale rights, which are key to libraries being able to share such content.19 “while drm of any sort is not desirable, if by using blockchain-driven drm we trade for the ability to have recognized digital first sale rights, it may be a worthy bargain for libraries.”20 to support such restrictions, another use for blockchain developed by companies such as libchain is open, verifiable, and anonymous access management to library content.21 another suitable application for blockchain is metadata creation and management.22 an open metadata archive, information ledger, or knowledgebase is very appealing because access to high quality records often requires a subscription to oclc.23 some libraries cannot afford such subscriptions. therefore, they must rely on records supplied by either a vendor or a government agency, like the library of congress. unfortunately, as of this writing, there is little research on how these blockchains could be constructed at the scale of large databases like those of oclc and the library of congress. in fact, the only such project is demco’s private, invitation-only beta.24 demco does not provide any information regarding their new product, but to make its development profitable, it is most likely a private, permissioned blockchain. creating permissionless blockchains for metadata records this section will describe how to create permissionless blockchains for metadata records including grouping transactions, an appropriate consensus algorithm, and storage options. please note that these blockchains are intended to augment current metadata record creation and modification practices and standards, not supersede them. the author assumes that record creation and modification will still require content (rda) and encoding (marc) validation prior to blockchain submission. validation in this section will refer solely to blockchain validation. generating and managing public and private keys all distributed ledger participants will need a public key or address for blocks of transactions to be sent to them and a private key for digital signatures. one way to create these key pairs is to generate a seed, which can be a group of random words or passphrases. the sha-256 algorithm can then be applied to this seed to create a private key.25 next, a public key can be generated from that private key using an elliptic curve digital signature algorithm.26 for additional security, the no need to ask | rubel 4 https://doi.org/10.6017/ital.v38i2.10822 public key can be hashed again using a different cryptographic hash function, such as ripemd160, or multiple hash functions, like bitcoin does to create its addresses.27 these key pairs could be managed with digital wallet software. “a bitcoin wallet is an organized collection of addresses and their corresponding private keys.”28 larger institutions, such as the library of congress, could have multiple key pairs with each pair designated for the appropriate cataloging department based on genre, form, etc. creating a genesis block every blockchain must start with a “genesis block.”29 for example, a personal name authority blockchain might start with william shakespeare’s record. a descriptive bibliographic blockchain might start with the king james bible. this genesis block includes a block header, a recipient’s public key or address, a transaction count, and a transaction list.30 being the first block, the block header will not contain a hash of the previous block header. it will contain, however, a hash of all of the transactions within that block to verify that the transactions list has not been altered. the block header will also include a timestamp and possibly a difficulty level and nonce.31 then the block header is hashed using the sha-256 algorithm and encrypted with the creator’s private key to produce a digital signature. this digital signature will be appended to the end of the block so validators can verify that the creator made the block by using their (the creator’s) public key.32 finally, the recipient’s public key or address, the transaction count, and transaction list are appended to the block header.33 block header • hash of previous block header • hash of all transactions in that block • timestamp • difficulty level (if applicable) • nonce (if applicable) block • recipient public key or address • transaction count • transaction list • digital signature in her master of information security and intelligence thesis at ferris state university, amber snow investigated the feasibility of using blockchain to add, edit, and validate changes to woodbridge n. ferris’ authority record.34 as shown in figure 1, she began by creating a hash function using the sha-256 algorithm to encrypt the previous hash, the timestamp, the block number, and the metadata record. “the returned encrypt value is significant because the returned data is the encrypted data that is being committed as [a] mined block transaction permanently to ledger.”35 the ledger block, however, “contains the editor’s name, the entire encrypted hash value, and the prior blocks [sic] hashed value.”36 information technology and libraries | june 2019 5 figure 1. creating a sha-256 hash. next, as shown in figures 2 and 3, she created a genesis block with a prior hashed value of zero by ingesting ferris’ authority record as “a single line file that contains the indicator signposts for cataloging the record.”37 figure 2. ingesting woodbridge n. ferris' authority record.38 figure 3. woodbridge n. ferris' authority record as a genesis block. note the previoushash value is zero. snow noted that “the understanding and interpretation of the marc authority record’s signposts is not inherently relevant for the blockchain data processing.”39 to keep the scope narrow, she also avoided using public and private key pairs to exchange records between nodes. “the ri [research institution] blockchain does not necessarily require two users to agree…instead the ri blockchain is looking to commit and track single user edits to the record.”40 creating and submitting new blocks for validation once a genesis block has been created and distributed, any node on the network can submit new blocks to the chain. for metadata records, new blocks should contain either new records or multiple modifications to the same record with each field being treated as a transaction. when a no need to ask | rubel 6 https://doi.org/10.6017/ital.v38i2.10822 second block is appended, the new block header will include the hash of the previous block header, a hash of all of the new transactions, a new timestamp, and possibly a new difficulty level and/or nonce. the block header will then be hashed using sha-256 and encrypted with the submitter’s private key to become a digital signature for that block. finally, another recipient’s public key or address, a new transaction count, and a new transaction list will be appended to the block header. additional blocks can then be securely appended to the chain ad infinitum without losing any of the transactional details. if two validators approve the same block at the same time, then the fork where the next block is appended first becomes the valid chain while the other chain becomes orphaned.41 although snow’s method does not include exchanging records using public keys or addresses, she was able to change a record, add it to the blockchain, and successfully commit those edits using the proof of work consensus algorithm.42 as shown in figure 4, after creating and submitting a genesis block as “tester 1,” she added a modified version of woodbridge n. ferris’ record as “tester 2.” this version appended the string “testerchanged123” to woodbridge n. ferris’ authority record. then she validated or “mined” the second block to commit the changes. figure 4. submitting and validating an edited record. figure 5 shows that the second block is chained to the genesis block because the “previoushash” value of the second block matches the “hash” of the genesis block. this link is what commits the block to the ledger. the appended string in the second block is at the end of the “metadata” variable. information technology and libraries | june 2019 7 figure 5. the new authority record blockchain. a more sophisticated method to append a second block would require key pairs. as described previously, a block would include a recipient’s public key or address, which would route the new and modified records to large, known institutions like the library of congress. although every node on the network can see the records and all of the changes, large institutions with welltrained and authoritative catalogers may be the best repository for metadata records and could store a preservation or backup copy of the entire chain. they are also the most reliable for validating records for content accuracy and correct encoding. achieving algorithmic consensus once a block has been submitted for validation, the other nodes use a consensus algorithm to verify the validity of the block and its transactions. “consensus mechanisms are ways to guarantee a mutual agreement on a data point and the state…of all data.”43 the most well-known consensus algorithm is bitcoin’s proof of work, but the most suitable algorithm for permissionless metadata blockchains is a federated byzantine agreement. proof of work proof of work (pow) relies on a one-way cryptographic hash function to create a hash of the block header. this hash is easy to calculate, but it is very difficult to determine its components.44 to solve a block, nodes must compete to calculate the hash of the block header. to calculate the hash of a block header, a node must first separate it into its constituent components. the hash of the previous block header, the hash of all of the transactions in that block, the timestamp, and the difficulty target will always have the same inputs. the validator, however, changes the nonce or random value appended to the block header until the hash has been solved.45 in bitcoin this process is called “mining” because every new block creates new bitcoins as a reward for the node that solved the block.46 no need to ask | rubel 8 https://doi.org/10.6017/ital.v38i2.10822 bitcoin also includes a mechanism to ensure the average number of blocks solved per hour remains constant. this mechanism is the difficulty target. “to compensate for increasing hardware speed and varying interest in running nodes over time, the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. if they’re generated too fast, the difficulty increases.”47 adjusting the difficulty target within the block header keeps bitcoin stable because its block rate is not determined by its popularity.48 in sum, validators are trying to find a nonce that generates a hash of the block header that is less than the predetermined difficulty target. unfortunately, proof of work requires immense and ever-increasing computational power to solve blocks, which poses a sustainability and environmental challenge. bitcoin and other financial services may need to rely on proof of work because “the massive amounts of electricity required helps to secure the network. it disincentivizes hacking and tampering with transactions…”49 because an attacker would need to control over 51 percent of the entire network to convince the other nodes that a faulty ledger is correct.50 metadata blockchains would rely on public information and therefore would not need the same level of security as private financial, medical, or personally identifiable information. unlike bitcoin, metadata blockchains also would not need a difficulty target because fluctuations in block production rates would not affect a metadata block’s value the same way cryptocurrency inflation would. therefore, despite its incredible security, proof of work would be computationally excessive for metadata record blockchains. federated byzantine agreement byzantine agreements are “the most traditional way to reach consensus. […] a byzantine agreement is reached when a certain minimum number of nodes (known as a quorum) agrees that the solution presented is correct, thereby validating a block and allowing its inclusion on the blockchain.”51 byzantine fault-tolerant (bft) state machine replication protocols support consensus “despite participation by malicious (byzantine) nodes.”52 this support ensures consensus finality, which “mandates that a valid block…never be removed from the blockchain.”53 in contrast, proof of work does not satisfy consensus finality because there is still the potential for temporary forking even if there are no malicious nodes.54 the “absence of consensus finality directly impacts the consensus latency of pow blockchains as transactions need to be followed by several blocks to increase the probability that a transaction will not end up being pruned and removed from the blockchain.”55 this latency increases as block size increases, which may also increase the number of forks and possibility of attack.56 “with this in mind, limited performance is seemingly inherent to pow blockchains and not an artifact of a particular implementation.”57 bft protocols, however, can sustain tens of thousands of transactions at nearly network latency levels.58 a bft consensus algorithm is also superior to one based on proof of work because “users and smart contracts can have immediate confirmation of the final inclusion of a transaction into the blockchain.”59 bft consensus algorithms also decouple trust from resource ownership, allowing small organizations to oversee larger ones.60 to use bft, every node must know and agree on the exact list of participating peer nodes. ripple, a bft protocol, tries to ameliorate this problem by publishing an initial membership list and allowing members to edit that list after implementation. unfortunately, users are often reluctant to edit the membership list thereby placing most of the network’s power in the person or organization that maintains the list.61 information technology and libraries | june 2019 9 federated byzantine agreement (fba), however, does not require each node to agree upon and maintain the same membership list. “in fba, each participant knows of others it considers important. it waits for the vast majority of those others to agree on any transaction before considering the transaction settled.”62 theoretically, an attacker could join the network enough times to outnumber legitimate nodes, which is why quorums by majority would not work. instead, fba creates quorums using a decentralized method that relies on each node selecting its own quorum slices.63 “a quorum slice is the subset of a quorum convincing one particular node of agreement.”64 a node may have many slices, “any one of which is sufficient to convince it of a statement.”65 the system constructs quorums based on individual node decisions thereby generating consensus without every node being required to know about every other node in the system.66 one example of quorum slices that might be good for metadata blockchains is a tiered system as shown in figure 6. the top tier would be structured like a bft system where the nodes can tolerate a limited number of byzantine nodes at the same level. this level would include the core metadata authorities, such as the library of congress or pcc members. members of this tier would be able to validate any record. the second or middle tier nodes would depend on the top tier because, in this example, a middle tier node requires two top tier nodes to form a quorum slice. these middle tier nodes would be authoritative, known institutions, such as universities, that already rely on the core metadata authorities on the top tier to validate and distribute their records. finally, a third tier, such as smaller institutions, would, in this example, rely on at least two middle tier nodes for their quorum slice. figure 6. tiered quorum example. no need to ask | rubel 10 https://doi.org/10.6017/ital.v38i2.10822 using an fba protocol to validate a transaction requires each node to exchange two sets of messages. the first set of messages gathers validations and the second set of messages confirms those validations. “from each node’s perspective, the two rounds of messages divide agreement…into three phases: unknown, accepted, and confirmed.”67 the unknown status becomes an acceptance when the first validation succeeds. acceptance is not sufficient for a node to act on that validation, however, because acceptance may be stuck in an indeterminate state or blocked for other nodes.68 the accepting node may also be corrupted and validate a transaction the network quorum rejects. therefore, the confirmation validation “allows a node to vote for one statement and later accept a contradictory one.”69 figure 7. validation process of statement a for a single node v. fba would lessen concerns about sharing a permissionless blockchain, but it can “only guarantee safety when nodes choose adequate quorum slices.”70 after discovery, byzantine nodes should be excluded from quorum slices to prevent interference with validation. one example of such interference is tricking other nodes to validate a bad confirmation message. “in such a situation, nodes must disavow past votes, which they can only do by rejoining the system under new node names.”71 theoretically, this recovery process could be automated to include “having other nodes recognize reincarnated nodes and automatically update their slices.”72 therefore, the key limitation to using an fba algorithm is continuity of participation. if too many nodes leave the network, reengineering consensus would require centralized coordination whereas proof of work algorithms could operate after losing many nodes without substantial human intervention.73 storing the blockchain storing a large blockchain, such as bitcoin, is a significant challenge. one method to facilitate that storage would be to rely on top tier nodes to retain a complete copy of the blockchain and allow smaller, lower tier nodes to retain an abridged version. in bitcoin, these methods are known as full payment verification (fpv) and simplified payment verification (spv). fpv requires a complete copy of the blockchain to “verify that bitcoins used in a transaction originated from a mined block by scanning backward, transaction by transaction, in the blockchain until their origin is found.”74 unfortunately, as one might expect, fpv consumes many resources and can take a long time to initialize. for example, downloading bitcoin’s blockchain can take several days. this long installation period is partly due to the size of blockchain, but if proof of information technology and libraries | june 2019 11 work is used as the consensus algorithm, then the new node must also connect to other full nodes “to determine whose blockchain has the greatest proof-of-work total (by definition, this is assumed to be the consensus blockchain).”75 using fba instead of proof of work would eliminate this time and resource consuming step. in contrast, svp only allows a node “to check that a transaction has been verified by miners and included in some block in the blockchain.”76 a node does this by downloading the block headers of every block in the chain. in addition to retaining the hash of the previous block header, these headers also include root hashes derived from a merkle tree. a merkle tree is a method where “the spent transactions…can be discarded to save disk space.”77 as shown in figure 8, combining transaction hashes for the entire block into a single root hash in the block header saves a considerable amount of storage capacity because the interior hashes can be eliminated or “pruned” off the merkle tree. figure 8. using a merkle tree for storage. as shown in figure 9, to verify that a transaction was included a block, a node “obtains the merkle branch linking the transaction to the block it’s timestamped in.”78 although it cannot check the transaction directly, “by linking it to a place in the chain he can see that a network node has accepted it and blocks after it further confirm the network has accepted it.”79 no need to ask | rubel 12 https://doi.org/10.6017/ital.v38i2.10822 figure 9. verifying a transaction using a merkle root hash. compared to fvp, svp “requires only a fraction of the memory that’s needed for the entire blockchain.”80 this small amount of storage enables svp ledgers to sync and become operational in less than an hour.81 svp is limited, however, only allowing nodes to manage addresses or public keys that they maintain whereas fvp ledgers are able to query the entire network. thus, an svp ledger must rely “on its network peers to ensure its transactions are legit.”82 theoretically, an attacker could overpower the entire network and convince nodes using svp to accept fraudulent transactions, but such an attack is very unlikely for metadata blockchains. for additional security, an svp node could also “accept alerts from network nodes when they detect an invalid block, prompting the user’s software to download the full block and alerted transactions to confirm the inconsistency.”83 adding such a feature to metadata blockchain software would eliminate the slight risk of it being contaminated by malicious actors. thus, svp offers the ability for smaller institutions to participate in creating and maintaining a metadata blockchain without requiring them to have the storage capacity for the entire blockchain. conclusion and future directions this article described how permissionless metadata blockchains could be created to overcome two significant limitations in current cataloging practices: centralization and a lack of traceability. the process would start by creating public keys using a seed and the sha-256 algorithm and private keys using an elliptic curve digital signal algorithm. after creating the genesis block, nodes would submit either a new record or modifications to a single record for validation. validation would rely on a federated byzantine agreement (fba) consensus algorithm because it offers the most flexibility for institutions to select authoritative peers. quorum slices would be chosen using a tiered system where the top tier institutions would be the core metadata authorities, such as the library of congress. only the top tier nodes would be required to store a copy of the entire blockchain (fvp) thereby allowing other institutions to decide whether they prefer to use svp or fvp. information technology and libraries | june 2019 13 future directions for research could start with investigating whether this theoretical design will work. fba has not been heavily promoted as an option for a consensus algorithm, but its quorum slices create trust between recognized authorities and smaller institutions. another area of study could be whether there is a significant demand for metadata blockchains. many institutions appear frustrated at the costs and limitations of working with a vendor, but they also view such relationships as necessary for metadata record creation and maintenance. a metadata blockchain would reduce such dependence, but some institutions may be leery of using open source software. other institutions might be hesitant to adopt blockchain because they believe it is merely another “fad” or an unnecessary addition to metadata exchange systems. a third area for research could be a cost-benefit analysis for implementing metadata blockchains that weighs current vendor fees and labor costs against the potential storage and labor costs. such an analysis may create a tipping point where long-term return on investment outweighs the short-term challenges.

privacy and maximizing library resources public libraries leading the way on educating patrons on privacy and maximizing library resources t.j. lamanna information technology and libraries | september 2019 4 t.j. lamanna (professionalirritant@riseup.net) is an adult services librarian, cherry hill public library. abstract libraries are one of our most valuable institutions. they cater to people of all demographics and provide services to patrons they wouldn’t be able to get anywhere else. the list of services libraries provide is extensive and comprehensive, although unfortunately, there are significant gaps in what our services can offer, particularly those regarding technology advancement and patron privacy. though library classes on educating patrons’ privacy protection are a valiant effort, we can do so much more and lead the way, maybe not for the privacy industry but for our communities and patrons. creating a strong foundational knowledge will help patrons leverage these new skills in their day to day lives as well as help them educate their families about common privacy issues. in this column, we’ll explore some of the ways libraries can utilize their current resources as well as provide ideas on how we can maximize their effectiveness and roll new technologies into their operations. though many libraries have policies on how they deal with patron privacy, unfortunately some policies aren’t very strong and oftentimes staff isn’t trained in the details of these policies. fortunately, for libraries who don’t have these necessary policies, there are some, such as the san jose public library, that offer their own as a framework.1 those that do have a strong comprehensive policy must make sure they are enforcing and regularly updating it to comply with new technologies being released. it’s a daunting task, but as article vii of the library bill of rights says, “all people, regardless of origin, age, background, or views, possess a right to privacy and confidentiality in their library use. libraries should advocate for, educate about, and protect people’s privacy, safeguarding all library use data, including personally identifiable information.”2 this means we have a responsibility to our patrons to do everything in our power to protect them and teach them to protect themselves. this requires a concerted effort not just for technology and it librarians, but for all library workers. a privacy policy means little if those on the front lines are either unaware of the policy or unsure how it is to be implemented. therefore, all library staff should both understand the fundamental reasons behind library privacy policies and be trained in maintaining them. libraries may consider implementing this training during staff development days or offer independent training sessions as needed. since the introduction of the patriot act, libraries stopped collecting patrons’ reading habits, but so many library integrated library systems (ils) snag massive amounts of patron information we are unaware of. i’ve been administering our ils for over two years and i just found another space where items are being unnecessarily retained that i didn’t notice before. an instance such as this calls for limiting personally identifiable information (pii) to what is strictly necessary. mailto:professionalirritant@riseup.net on educating patrons on privacy and maximizing library resources | lamanna 5 https://doi.org/10.6017/ital.v38i3.11571 in limiting the pii gathered in the first place, library staff should consider the following questions: what information do libraries really need to collect to offer library cards or programming? does your library really need patrons’ date of birth or gender? probably not. if so, you shouldn’t be collecting it, and if you do, make sure you anonymize the data. using metrics is vital to how libraries function, receive funding, and schedule programming. you can still use the information, but it should not be connected to a patron in any way. after educating staff, we can educate patrons on developing better and safer practices regarding personal privacy and security in their daily lives. practical examples range from teaching patrons how to create strong passwords and backup sensitive files to explaining how malware works and what the “cloud” actually is. this is a start, but it goes far beyond that. i’ve served many patrons who, even after taking courses on the subject, are overwhelmed by the security measures needed to protect themselves. this isn’t necessarily a sign that our classes are ineffective, but it does imply that new tactics are needed. let’s look at a few examples. another version of pii that we often overlook are security measures such as closed-circuit television (cctv) or security/police officers in our buildings.3 they often are either forgotten or outside the purview of the library itself. as the college of policing states, “cctv is more effective when directed at reducing theft of and from vehicles, while it has no impact on levels of violent crime.”4 while there are justifications for bringing this technology into the library, they should only be set up where needed, taking great care not to point them at patron or staff computers. if cctv is needed, make sure to follow local retention laws and remove the footage as soon as its time has expired. this idea applies to all collected information. there is no reason to archive data beyond the date they can be destroyed as it puts the library and its patrons in a compromised position. law enforcement in the library is a tough thing to argue against in our current political climate. but studies have shown that police presence does little to deter crime and may actually disproportionately impact marginalized communities.5 consider the purpose of law enforcement personnel and if their presence is actually necessary to the proper functioning of your library. in the event that you should have law enforcement come in with a subpoena that requires you to turn over your patron data, it’s important to have a canary warning that can be removed so your patrons understand what has happened.6 another way libraries can lead the way in protecting patron privacy both inside and outside the library is by supporting legislation that bans facial recognition software. this type of technology is becoming ubiquitous, but places have already started pushing back and libraries can be the epicenter of this movement. it’s already been banned in oakland,7 san francisco8 (one of the homes of this technology), as well as somerville, massachusetts, with groups like the massachusetts library association unanimously putting out a moratorium on facial surveillance, which is the practice of recording ones face to create user profiles.9 there are other states that are working down this path and it’s overwhelmingly heartening to see libraries step up and in front of something they know would damage our communities. we ought to be activists, standing on the front lines and showing our patrons our deepest commitment to them. surely there are greater strides we can make, such as revising wifi policies. wifi is one of the most used services libraries offer and many libraries don’t use it to their full potential. for instance, some libraries turn off their wifi when the building is closed, severely limiting patrons’ information technology and libraries | september 2019 6 usage. it’s a service we pay for and there is no reason it shouldn’t be available at all times. your it service should make sure the wifi is secure (it should be where it’s available at all hours or not). unlimited access to wifi becomes invaluable to users who need it for emergencies including completing work or accessing important online services when the library is closed. while we do have limited bandwidth and it services must actively maintain wifi security, libraries should make sure it’s available to the public as often as possible. now that we’ve covered using bandwidth when we aren’t open, let’s talk about libraries with excess bandwidth. no resource should go unused in the library. we have a limited budget and we should make sure every penny is used to serve our communities. one fantastic use of excess bandwidth — especially during closed hours — would be to set up a tor relay in your library, an anonymity network that allows people to surf the internet with extra security and privacy in mind. it’s quite easy to set up and you can limit how much bandwidth it uses so you aren’t shorting anyone in your library. it’s a service used by groups such as journalists or activists who want to make positive change in the world and need a safe place to do so. some are concerned that the tor network is used for malicious intent but the tor project, the organization that runs the network, constantly works to ensure nothing like that is taking place. also, anything solicitous you can find on the tor network is available on the regular internet including places like facebook or craigslist, so the stigma of the network should be taken in context. the tor project routinely monitors the network and searches out illegal material (there are no hired killers on the tor network). given all this, you could help the network greatly by just partitioning a small amount of your bandwidth. libraries have the unique ability to be transformative. unlike other non-profits or organizations, we have the ability to pivot. we can both change directions as needed and pave the way for our communities as leaders in the movement toward patron privacy. i leave you with a quote from hardt and negri: “…we share common dreams of a better future.”10 that should be our motto. endnotes 1 “our privacy policy, san jose public library, accessed august 15, 2019,

open data in cataloging irfan ullah, shah khusro, asim ullah, and muhammad naeem information technology and libraries | december 2018 47 irfan ullah (cs.irfan@uop.edu.pk) is doctoral candidate, shah khusro (khusro@uop.edu.pk) is professor, asim ullah (asimullah@uop.edu.pk) is doctoral student, and muhammad naeem (mnaeem@uop.edu.pk) is assistant professor, at the department of computer science, university of peshawar. abstract linked open data (lod) is a core semantic web technology that makes knowledge and information spaces of different knowledge domains manageable, reusable, shareable, exchangeable, and interoperable. the lod approach achieves this through the provision of services for describing, indexing, organizing, and retrieving knowledge artifacts and making them available for quick consumption and publication. this is also aligned with the role and objective of traditional library cataloging. owing to this link, major libraries of the world are transferring their bibliographic metadata to the lod landscape. some developments in this direction include the replacement of anglo-american cataloging rules 2nd edition by the resource description and access (rda) and the trend towards the wider adoption of bibframe 2.0. an interesting and related development in this respect are the discussions among knowledge resources managers and library community on the possibility of enriching bibliographic metadata with socially curated or user-generated content. the popularity of linked open data and its benefit to librarians and knowledge management professionals warrant a comprehensive survey of the subject. although several reviews and survey articles on the application of linked data principles to cataloging have appeared in literature, a generic yet holistic review of the current state of linked and open data in cataloging is missing. to fill the gap, the authors have collected recent literature (2014–18) on the current state of linked open data in cataloging to identify research trends, challenges, and opportunities in this area and, in addition, to understand the potential of socially curated metadata in cataloging mainly in the realm of the web of data. to the best of the authors’ knowledge, this review article is the first of its kind that holistically treats the subject of cataloging in the linked and open data environment. some of the findings of the review are: linked and open data is becoming the mainstream trend in library cataloging especially in the major libraries and research projects of the world; with the emergence of linked open vocabularies (lov), the bibliographic metadata is becoming more meaningful and reusable; and, finally, enriching bibliographic metadata with user-generated content is gaining momentum. conclusions drawn from the study include the need for a focus on the quality of catalogued knowledge and the reduction of the barriers to the publication and consumption of such knowledge, and the attention on the part of library community to the learning from the successful adoption of lod in other application domains and contributing collaboratively to the global scale activity of cataloging. introduction with the emergence of the semantic web and linked open data (lod), libraries have been able to make their bibliographic data publishable and consumable on the web, resulting in an increased understanding and utility both for humans and machines.1 additionally, the use of linked data principles of lod has allowed connecting related data on the web.2 traditional catalogs as mailto:cs.irfan@uop.edu.pk mailto:khusro@uop.edu.pk mailto:asimullah@uop.edu.pk mailto:mnaeem@uop.edu.pk current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 48 https://doi.org/10.6017/ital.v37i4.10432 collections of metadata about library content have served the same purpose for a long time.3 it is, therefore, natural to establish a link between the two technologies and exploit the capabilities of lod to enhance the power of cataloging services. in this regard, significant milestones have been achieved, which includes the use of linked and open data principles for publishing and linking library catalogs, bibframe, and europeana data model (edm).4 however, the potential of linked and open data for building more efficient libraries and the challenges involved in that direction are mostly unknown due to the lack of a holistic view of the relationship between cataloging and the lod initiative and the advances made in both areas. likewise, the possibility of enriching the bibliographic metadata with user-generated content such as ratings, tags, and reviews to facilitate the search for known-items as well as exploratory search has not received much attention. 5 some studies of preliminary extent have, however, appeared in literature an overview of which is presented in the following paragraphs. several survey and review articles have contributed to different aspects of cataloging in the lod environment. hallo et al. investigated how linked data is used in digital libraries, how the major libraries of the world implemented it, and how they benefit from it by focusing on the selected ontologies and vocabularies. 6 they identified several specific challenges to applying linked data to digital libraries. more specifically, they reviewed the linked data applications in digital libraries by analyzing research publications regarding the major national libraries (obtaining five-stars by following linked data principles) and published from 2012 to 2016.7 tallerås examined statistically the quality of linked bibliographic data published by the major libraries including spain, france, the united kingdom, and germany. 8 yoose and perkins presented a brief survey of lod uses under different projects in different domains including libraries, archives, and museums.9 by exploring the current advances in the semantic web, robert identified the potential roles of libraries in publishing and consuming bibliographic data and institutional research output as linked and open data on the web.10 gardašević presented a detailed overview of semantic web and linked open data from the perspective of library data management and their applicability within the library domain to provide a more open and integrated catalog for improved search, resource discovery, and access.11 thomas, pierre-yves, and bernard presented a review of linked open vocabularies (lov), in which they analyzed the health of lov from the requirements perspective of its stakeholders, its current progress, its uses in lod applications, and proposed best practices and guidelines regarding the promotion of lov ecosystem.12 they uncovered the social and technical aspects of this ecosystem and identified the requirements for the long-term preservation of lov data. vandenbussche et al. highlighted the features, components, significance, and applications of lov and identified the ways in which lov supports ontology & vocabulary engineering in the publication, reuse and data quality of lod.13 tosaka and park performed a detailed literature review of rda (2005–11) and identified its fundamental differences from aacr2, its relationship with the metadata standards, and its impact on metadata encoding standards, users, practitioners, and the training required.14 sprochi presented the current progress in rda, frbr (functional requirements for bibliographic records), and bibframe to predict the future of library metadata, the skills and knowledge required to handle it, and the directions in which the library community is heading. 15 gonzales identified the limitations of marc21 and the benefits of and challenges in adopting the bibframe information technology and libraries | december 2018 49 framework.16 taniguchi assessed bibframe 2.0 for the exchange and sharing of metadata created in different ways for different bibliographic resources.17 he discussed bibframe 1.0 from rda point of view.18 he examined bibframe 2.0 from the perspective of rda to uncover issues in its mapping to bibframe including rda expressions in bibframe, mapping rda elements to bibframe properties, and converting marc21 metadata records to bibframe metadata. 19 fayyaz, ullah, and khusro reported on the current state of lod and identified several prominent issues, challenges, and research opportunities. 20 ullah, khusro, and ullah reviewed and evaluated different approaches for bibliographic classification of digital collections.21 by looking at the above survey and review articles, one may observe that these articles target a specific aspect of cataloging from the perspective of lod. the holistic analysis and a complete picture of the current state of cataloging in transiting to lod ecosystem are missing. this paper adds to the body of knowledge by filling this gap in the literature. more specifically, it attempts to answer the following research questions (rqs): rq01: how linked open data (lod) and vocabularies (lov) are transforming the digital landscape of library catalogs? rq02: what are the prominent/major issues, challenges, and research opportunities in publishing and consuming bibliographic metadata as linked and open data? rq03: what is the possible impact of extending bibliographic metadata with the usergenerated content and making it visible on the lod cloud? the first section of this paper answers rq01 by discussing the potential role of lod and lov in making library catalogs visible and reusable on the web. the second section answers rq02 by identifying some of the prominent issues, challenges, and research opportunities in publishing, linking, and consuming library catalogs as linked data. it also identifies specific issues in rda and bibframe from lod perspective and highlights the quality of lod-based cataloging. the third section answers rq03 by reviewing the state-of-the-art literature on the socially curated metadata and its role in cataloging. the last section concludes the paper followed by references cited in this article. the role of linked open data and vocabularies in cataloging the catalogers, librarians, and information science professionals have always been busy defining the set of rules, guidelines, and standards to record the metadata about knowledge artifacts accurately, precisely, and efficiently. the aacr2 are among the widely used rules and guidelines for cataloging. however, it has several issues with the nature of authorship, the relationships between bibliographic metadata, the categorization of format-specific resources, and the description of new data types.22 in an attempt to produce its revised version, aacr3, the cataloging community noticed that a new framework should be developed with the name of rda.23 based on frbr conceptual models, rda is a “flexible and extendible bibliographic framework” that supports data sharing and interoperability and is compatible with marc21 and aacr2.24 according to the rda toolkit, rda describes digital and non-digital resources by taking advantage of the flexibilities and efficiencies of modern information storage and retrieval technologies while at the same time is backward-compatible with legacy technologies used in conventional resource discovery and access applications.25 it is aligned with the ifla’s current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 50 https://doi.org/10.6017/ital.v37i4.10432 (international federation of library associations and institutions) conceptual models of authority and bibliographic metadata (frbr, frad [functional requirements for authority data], frsad [functional requirements for subject authority data]).26 rda accommodates all types of content and media in digital environments with improved bibliographic control in the realm of linked and open data; however, its responsiveness to user requirements needs further research.27 the discussion of the cataloging rules and guidelines stays incomplete without the metadata encoding standards and formats that give practical shape to these rules in the form of library catalogs. the most common encoding formats include dublin core (dc) and marc21. dublin core (http://lov.okfn.org/dataset/lov/vocabs/dce) is a [general-purpose metadata encoding scheme and] vocabulary of fifteen properties with “broad, generic, and usable terms” for resource description in natural language. it is advantageous as it presents relatively low barriers to repository construction; however, it lacks in standards to index subjects consistently as well as to offer a uniform semantic basis necessary for an enhanced search experience.28 the lack of uniform semantic basis is due to the individual interpretations and exploitations of dc metadata by the libraries, which in turn originated from its different and independent implementations at the element level.29 marc21 is the most common machine process-able metadata encoding format for bibliographic metadata. it can be mapped to several formats including dc, marc/xml (http://www.loc.gov/standards/marcxml/), mods (http://www.loc.gov/standards/mods), mads (http://www.loc.gov/standards/mads), and other metadata standards.30 however, marc21 has several limitations such as only library software and librarians understand it, it is semantically inexpressive and isolated from the web structure, and it lacks in expressive semantic connections to relate different data elements in a single catalog record.31 besides its limitations, marc metadata encoding format is vital for resource discovery especially within the library environment, and therefore, ways must be found to make visible the library collections outside the libraries and available through the major web search engines.32 one such effort is from the library of congress (http://catalog.loc.gov/) that introduced a new bibliographic metadata framework, bibframe 2.0, which will eventually replace marc21 and allow semantic web and linked open data to interlink bibliographic metadata from different libraries. other metadata encoding schema and frameworks include schema.org, edm, and the international community for documentation (cidoc)’s conceptual reference model (cidoc-crm).33 today, the bibliographic metadata records are available on the web in several forms including marc21, online public access catalogs (opacs), and bibliographic descriptions from online catalogs (e.g., library of congress), online cooperative catalogs (e.g., oclc’s worldcat [https://www.oclc.org/en/worldcat.html program]), social collaborative cataloging applications (e.g., librarything [https://www.librarything.com]), digital libraries (e.g., ieee xplore digital library [https://ieeexplore.ieee.org/xplore/home.jsp]), acm digital library(https://dl.acm.org), book search engines such as google books, and commercial databases including e.g., amazon.com. most of these cataloging web applications use either marc or other legacy standards as metadata encoding and representation schemes. however, the majority of these applications are either considering or transiting to the emerging cataloging rules, frameworks, and encoding schemes so that the bibliographic descriptions of their holdings could be made visible and reusable as linked and open data on the web for the broader interests of libraries, publishers, and end-users. http://lov.okfn.org/dataset/lov/vocabs/dce http://www.loc.gov/standards/marcxml/ http://www.loc.gov/standards/mods http://www.loc.gov/standards/mads http://catalog.loc.gov/

of high-quality reusable vocabularies makes the consumption of linked data more meaningful, which is made possible by linked open vocabularies (lov) that bring value-added extensions to the web of data.34 the following two subsections attempt to answer the rq01 by highlighting how lod and lov are transforming the current digital landscape of cataloging. linked and open data the semantic web and linked open data have enabled libraries to publish and make visible their bibliographic data on the web, which increases the understanding and consumption of this metadata both for humans and machines.35 lod connects and relates bibliographic metadata on the web using linked data principles.36 publishing, linking, and consuming bibliographic metadata as linked and open data brings several benefits. these include improvements in data visibility, linkage with different online services, interoperability through universal lod platform, and the credibility due to user annotations.37 other benefits include: the semantic modeling of entities related to bibliographic resources; ease in transforming topics into skos; ease in the usage of linked library data in other services; better data visualization according to user requirements; linking and querying linked data from multiple sources; and improved usability of library linked data in other domains and knowledge areas.38 different users including scientists, students, citizens and other stakeholders of library data can benefit from adopting lod in libraries.39 linked data has the potential to make bibliographic metadata visible, reusable, shareable, and exchangeable on the web with greater semantic interoperability among the consuming applications. several major projects including bibframe, lodlam (linked open data in libraries archives and museums [http://lodlam.net]), and ld4l (linked data for libraries [https://www.ld4l.org]) are in progress, which advocates for this potential.40 similarly, library linked data (lld) is lod-based bibliographic datasets, available in mods and marc21 and could be used in making search systems more sophisticated and may also be used in lov datasets to integrate applications requiring library and subjects domain datasets.41 bianchini and guerrini report on the current changes in the library and cataloging domains from ranganathan’s point of view of trinity (library, books, staff), which states that changes in one element of this trinity undoubtedly affect the others.42 they found several factors including readers, collections, and services influence this trinity and emphasize for a change: • readers moved to the web from libraries and wanted to save their time but want many capabilities including searching and navigating the full-text of resources by following links. they want resources connected to similar and related resources. they want concepts interlinked to perform an exploratory search, find serendipitous results to fulfill their information needs. • collections encompass several changes from their production to dissemination, from search and navigation to the representation and presentation of content. the ways the users access them and catalogers describe them are changing. their management is moving beyond the boundaries of their corresponding libraries to the open and broader landscape of open access context and exposure to lod environment. • services are moving from bibliographic data silos to the semantic web. this affects moving the bibliographic model to a more connected and linked data model and environment of semantic web. the data is moving from bibliographic database management systems to large lod graph, where millions of marc records are reused and converted to new http://lodlam.net/ https://www.ld4l.org/ current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 52 https://doi.org/10.6017/ital.v37i4.10432 encoding formats that are backward compatible with marc21, rda, and others and provide opportunities to be exploited fully by the linked and open data environment. thinking along this direction, new cataloging rules and guidelines, such as rda, are making us a part of the growing global activity of cataloging. therefore, catalogers should take keen interest in and avail themselves of the opportunities that lie in linked and open data for cataloging. otherwise, they (as a service) might be forgotten or removed from the trinity, i.e., from collections and readers.43 several major libraries have been actively working to make their bibliographic metadata visible and re-usable on the web. the library of congress through its linked data service (http://id.loc.gov) enables humans and machines to access its authority data programmatically. 44 it exposes and interconnects data on the web through dereferenceable uniform resource identifiers (uris).45 its scope includes providing access to the commonly found loc standards and vocabularies (controlled vocabularies and data values) for the list of authorities and controlled vocabularies that loc currently supports.46 according to the loc, the linked data service brings several benefits to the users including: accessing data at no cost; providing granular access to individual data values; downloading controlled vocabularies and their data values in numerous formats; enabling linking to loc data values within the user metadata using linked data principles; providing a simple restful api, clear license and usage policy for each vocabulary; accessing data across loc divisions through a unified endpoint; and visualizing relationships between concepts and values.47 however, to fully exploit the potentials of lod, loc is mainly focusing on its bibframe initiative.48 bibframe is not only a replacement for the current marc21 metadata encoding format it is a new way of thinking how the available large amount of bibliographic metadata could be shared, reused, and made available as linked and open data. 49 the bibframe 2.0 (https://www.loc.gov/bibframe/docs/bibframe2-model.html) model organizes information into work (the details of the about the work information), instance (work on specific subject quantity in numbers), item (format: print or electronic), and nature (copy/original work). bibframe 2.0 elaborates the roles of the persons in the specific work as agents, and the subject of the work as subjects and events.50 according to taniguchi, bibframe 2.0 takes the bibliographic metadata standards to the linked and open data with model and vocabulary that makes the cataloging more useful both inside and outside the library community.51 to achieve this goal, it needs to fulfill two primary requirements. these include (1) accepting and representing metadata created with rda by replacing the marc21, and therefore, working as creating, exchanging, and sharing rda metadata; (2) accepting and accommodating descriptive metadata for bibliographic resources created by libraries, cultural heritage communities, and users for the wide exchange and sharing. bibframe 2.0 should comply with the linked data principles including the use of rdf and uris. in addition to the library of congress, oclc through its linked data research has also been actively involved in research on transforming and publishing its bibliographic metadata as linked data.52 under this program, oclc aims to provide a technical platform for the management and publication of its rdf datasets at a commercial scale. it models the key bibliographic entities including work and person and populates them with legacy and marc-based metadata. it extends http://id.loc.gov/ https://www.loc.gov/bibframe/docs/bibframe2-model.html information technology and libraries | december 2018 53 models to efficiently describe the contents of digital collections, art objects, and institutional repositories, which are not very well-described in marc. it improves the bibliographic description of works and their translations. it manages the transition from marc and other legacy encoding formats to linked data and develops prototypes for native consumption of linked data to improve resource description and discovery. finally, it organizes teaching and training events.53 since 2012, oclc has been publishing bibliographic data as linked data with three major lod datasets including oclc persons, worldcat works, and worldcat.org.54 inspired from google research, currently, they have been working on knowledge vault pipeline process to harvest, extract, normalize, weigh, and synthesize knowledge from bibliographic records, authority files, and the web to generate linked data triples to improve the exploration and discovery experience of end-users.55 worldcat.org publishes it bibliographic metadata as linked data by extracting a rich set of entities including persons, works, places, events, concepts, and organizations to make possible several web services and functionalities for resource discovery and access.56 it uses schema.org (http://schema.org) as the base ontology, which can be extended with different ontologies and vocabularies to model worldcat bibliographic data to be published and consumed as linked data.57 tennant presents a simple example of how this works. suppose we want to represent the fact “william shakespeare is the author of hamlet” as linked data.58 to do this, the important entities should be extracted along with their semantics (relationships) and represented in a format that is both machine-processable and human-readable. using schema.org, virtual international authority file (viaf.org), and worldcat.org, the sentence can be represented as a linked data triple, as shown in figure 1 based on tennant.59 the digital bibliography & library project (dblp) is an online computer science bibliography that provides bibliographic information about major publications in computer science with the goal of providing free access to high-quality bibliographic metadata and links to the electronic version of these publications.60 as of october 2018, it has indexed more than 4.3 million publications from more than 2.1 million authors and has indexed more than 40,000 journal volumes, 38,000 conference/workshop proceedings, and more than 80,000 monographs.61 its dataset is available on lod that allows for faceted search and faceted navigation to the matching publications. it uses growbag graphs to create topic facets and uses dblp++ datasets (an enhanced version of dblp) and additional data extracted from the related webpages on the web.62 a mysql database stores the dblp++ dataset that is accessible through several ways including (1) getting the database dump; (2) using its web services; (3) using d2r server to access it in rdf; and (4) getting the rdf dump available in n3 serialization.63 the above discussions on loc, oclc, and dblp make it clear that lod can potentially transform the cataloging landscape of libraries by making bibliographic metadata visible and reusable on the web. however, this potential can only be exploited to its fullest if relevant vocabularies are provided to make the linked data more meaningful. lov fulfills this demand for relevant and standard vocabularies, discussed in the next subsection. current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 54 https://doi.org/10.6017/ital.v37i4.10432 figure 1. an example of publishing a sample fact as linked data (based on tennant64). linked open vocabularies linked open vocabularies (lov) are a “high-quality catalog of reusable vocabularies to describe linked and open data.”65 they assist publishers in choosing the appropriate vocabulary to efficiently describe the semantics (classes, properties, and data types) of the data to be published as linked and open data.66 lov interconnect vocabularies, version control, the property type of values to be matched with a query to increase the score of the terms, and offers a range of data access methods including apis, sparql endpoint, and data dump. the aim is to make the reuse of well-documented vocabularies possible in the lod environment.67 the lov portal brings valueadded extensions to the web of data, which is evident from its adoption in several state-of-the-art applications.68 the presence of vocabulary makes the corresponding linked data meaningful, if the original vocabulary vanishes from the web, linked data applications that rely on it no longer function because they cannot validate against the authoritative source. lov systems prevent vocabularies from becoming unavailable by providing redundant or back-up locations for these vocabularies.69 the lov catalog meets almost all types of search criteria including search using metadata, ontology, apis, rdf dump, and sparql endpoint enabling it to provide a range of services regarding the reuse of rdf vocabularies.70 linked data should be accompanied by its meaning to achieve its benefits, which is possible using vocabularies especially rdf vocabularies that are also published as linked data and linked with each other forming an lov ecosystem.71 such an ecosystem defines the health and usability of linked data by making its meaningful interpretation possible.72 for an ontology or vocabulary to be included into the lov catalog, it must be of an appropriate size with low-level and normalized information technology and libraries | december 2018 55 constraints and represented in rdfs or web ontology language (owl); it must allow creating instances and support documentation by permitting comments, labels, definitions, and descriptions to support end users.73 the ontology must have additional characteristics such as those described in semantic web languages like owl, published on the web with no limitations on its reuse, and support for content negotiation using searchable content and namespace uris .74 the lov catalog offers four core functionalities that make it more attractive for libraries. the aggregate accesses vocabularies through dump file or (a sparql) endpoint. the search finds classes/properties in a vocabulary or ontology. the stat displays descriptive statistics of lov vocabularies. finally, suggest enables the registry of new vocabularies.75 radio and hanrath uncovered the concerns regarding transitioning to lov including how preexisting terms could be mapped while considering the potential semantic loss.76 they describe this transition in the light of a case study at the university of kansas institutional repository, which adopted oclc’s fast vocabulary and analyzed the outcomes and impact of exposing their data as linked data. to them, a vocabulary that is universal in scope and detail can become “bloated” and may result in an aggregated list of uncontrolled terms. however, such a diverse system may be capable of accurately describing the contents of an institutional repository. in this regard, adopting linked data vocabulary may serve to increase the overall quality of data by ensuring consistency with greater exposure of the resources when published as lod. however, such a transition to a linked data vocabulary is not that simple and gets complicated when the process involves reconciling the legacy metadata especially when dealing with the issues of under or misrepresentation.77 publishers, commercial entities, and data providers such as universities are taking keen interest and consortial participation, and therefore the library community must contribute to, benefit from, and consider this inevitable opportunity seriously.78 considering, the core role of libraries in connecting people to the information, they should come forward to make available their descriptive metadata collections as linked and open data for the benefit of the scholarly community on the web. it is time to move from strings (descriptive bibliographic records) to things (data items) that are connected in a more meaningful manner for the consumption of both machines and humans.79 besides the numerous benefits of the lov, there are some well-documented [and well-supported] vocabularies that are “not published or no longer available.”80 while focusing on the mappings between schema.org and lov, nogales et al. argue that the lov portal is limited as “some of the vocabularies are not available here.”81 in other words, the lov portal is growing, but currently, it is at the infant stage, where much work is needed to bring all or at least the missing welldocumented and well-supported vocabularies. this way the true benefits of lov could be exploited to the fullest when such vocabularies are linked and made available for the consumption and reuse of the broader audience and applications of the web of data. challenges, issues, and research opportunities to answer the rq02, this section attempts to identify some of the prominent/key challenges and issues regarding publishing and consuming bibliographic metadata as linked and open data. the sheer scale and diversity of cataloging frameworks, metadata encoding schemes, and standards make it difficult to approach cataloging effectively and efficiently. the quality of the cataloging data is another dimension that needs proper attention. current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 56 https://doi.org/10.6017/ital.v37i4.10432 the multiplicity of cataloging rules and standards the importance and critical role of standards in cataloging are clear to everyone. with standards, it becomes possible to identify authors uniquely; link users to the intended and the required resources; assess the value and usage of the services a library or information system provides; operate efficiently different transactions regarding bibliographic metadata, link content, preserve metadata, and generate reports; and enable the transfer of notifications, data, and events across machines.82 the success of these standards is because of the community-based efforts and their utility for a person/organization and ease of adoption. 83 however, we are living in a “jungle of standards” with massive scale and complexity.84 we are facing a flood of standards, schemas, protocols, and formats to deal with bibliographic metadata. 85 it is necessary to come up with some uniform and widely accepted standard, schema, protocol, and format, which will make possible the uniformity between bibliographic records and make way for records de-duplication on the web. also, because of the exponential growth of the digital landscape of document collections and the emerging yet widely adopted linked data environment, it becomes necessary for librarians to be part of this global scale activity of making their bibliographic data available as linked and open data.86 therefore, all these standards need reenvisioning and reconsideration when libraries transit from the current implementations to a more complex lod-based environment.87 rda is easy to use, user-centric, and retrieval-supportive with a precise vocabulary.88 however, it has lengthier descriptions with a lot of technical terms, is time-consuming, needs re-training, and suffers from the generation gap.89 rda is transitioning from aacr2 to produce metadata for knowledge artifacts, and it will be adaptive to the emerging data structures of linked data.90 although librarians could potentially play a vital role in making rda successful, it is challenging to bring them on the same page with publishers and vendors.91 while studying bibframe 2.0 from rda point of view, taniguchi observed that: • bibframe has no class correspondence with rda, especially making a distinction between work and expression is challenging. • some rda elements have no corresponding properties in bibframe, and therefore, cannot be expressed in bibframe. in other cases, bibframe properties cannot be converted back to rda elements due to the many-to-one and many-to-many mappings between them. • the availability of multiple marc21-to-bibframe tools results in the variety of bibframe metadata, which makes its matching and merging in the later stages challenging.92 to understand whether bibframe 2.0 is suitable as a metadata schema, taniguchi examined it closely for domain constraint of properties and developed four additional methods for implementing such constraints, i.e., defining properties in bibframe.93 in these methods, method 1 is the strictest one for defining such properties, method 2 from bibframe, and the remaining gradually loosen. method 1 defines the domain of individual properties as work or instance only, which is according to the method in rda. method 2 defines properties using multiclass structure (work-instance-item) for descriptive metadata. method 3 introduces a new class bibres to accommodate work and instance properties. method 4 uses two classes bibres and work for representing a bibliographic resource. method 5 leaves the domain of any property unspecified and uses rdf:type to represent whether a resource belongs to the work or instance. he observed that: information technology and libraries | december 2018 57 • the multi-class structure used in bibframe (method 2) questions the consistency between this structure and the domain definition of the properties. • if the quality of the metadata is concerned especially matching among converted metadata from different source metadata, then method 1 works better than method 2. • if metadata conversion from different sources is required, then method 4 or 5 should be applied.94 taniguchi concludes that bibframe’s domain constraint policy is unsuitable for descriptive metadata schema to exchange and share bibliographic resources, and therefore, should be reconsidered.95 according to sprochi, bibliographic metadata is passing through a significant transformation. 96 frbr, rda, and bibframe are among the three major and currently running programs that will affect the recording, storage, retrieval, reuse and sharing of bibliographic metadata. ifla focuses on reconciling frbr, frad, and frsad models into one model namely frbr-library reference model (rfbr-lrm [https://www.ifla.org/node/10280]), published in may 2016.97 sprochi further adds that it is generally expected that by adopting this new model, rda will be changed and revised significantly. bibframe will also get substantial modifications to become compatible with frbr-lrm and the resulting rda rules.98 these initiatives, on the one hand, makes possible their visibility on the web, but on the other hand, introduces several changes and challenges for the library and information science community.99 to cope with the challenges of making bibliographic data visible, available, reusable, and shareable on the web, sprochi argues that: 100 • the library and information science community must think of the bibliographic records in terms of data that is both human-readable and machine-understandable, which can be processed across different applications and databases with no format restrictions. also, this data must support interoperability among vendors, publishers, users, and libraries and therefore, should be thought of beyond the notion that “only library create quality metadata (as quoted in coyle (2007)” and cited by sprochi101). • a shared understanding of semantic web, lod, data formats, and other related technologies is necessary for the library and information science community for more meaningful and fruitful conversations with software developers, information & library science (ils) designers, and it & linked data professionals. at least some basic knowledge about these technologies will enable the library community to take active participation in publishing, storing, visualizing, linking, and consuming bibliographic metadata as linked and open data. • the library community must show a strong commitment to more ils vendors to “postmarc” standards such as bibframe or any other standard that is supportive of the lod environment. this way we will be in a better position to exploit linked data and semantic web to their fullest. the library community must be ready to adopt lod in cataloging. transitioning from marc to linked data needs collaborative efforts and requires addressing several challenges. these challenges include: https://www.ifla.org/node/10280 current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 58 https://doi.org/10.6017/ital.v37i4.10432 • committing to a single standard by getting all units in the library, so that the big data problem resulting from using multiple metadata standards by different institutions could be mitigated; • bringing individual experts, libraries, university, and governments to work together and organize conferences, seminars, and workshops to bring linked data into the mainstream ; • translating the bibframe vocabulary into other languages; • involving different users and experts in the area; and • obtaining funding from the public sector and other agencies to continue the journey towards linked data.102 in the current scenario of metadata practices, the interoperability for the exchange of metadata varies across different formats.103 the semantic web and lod support different library models such as frbroo, edm, and bibframe. these conceptual models and frameworks suffer from the interoperability issue, which makes data integration difficult. currently, several options are available for encoding bibliographic data to rdf (and to lod), which further complicates the interoperability and introduces inconsistency.104 existing descriptive cataloging methodologies and the bibliographic ontology descriptions in cataloging and metadata standards set the stage for redesigning and developing better ways of improved information retrieval and interoperability.105 besides the massive heaps of information on the web, the library community (especially digital libraries) has devised standards for metadata and bibliographic description to meet the interoperability requirements for this part of the data on the web.106 semantic web technologies could be exploited to make information presentation, storage, and retrieval more user-friendly for digital libraries.107 to achieve such interoperability among resources, castro proposed an architecture for semantic bibliographic description.108 gardašević emphasizes on employing information system engineers and developers to understand resource description, discovery, and access process in libraries and then extend these practices by applying linked data principles.109 this way bibliographic metadata will be more visible, reusable and shareable on the web. godby, wang, and mixter stress collaborative efforts to establish a single and universal platform for cataloging rules, encoding schema, and model to a higher level of maturity, which requires initiatives such as rda, bibframe, ld4l, and biblow (https://bibflow.library.ucdavis.edu/about).110 the massive volume of metadata (available in marc and other legacy formats) makes data migration to bibframe challenging.111 although bibframe challenges the conventional ground of cataloging, which aims to record tangible knowledge containers, it is still in the infant stage at both theoretical and practical levels.112 for bibframe to be more efficient, enhanced, and enriched, it needs the attention of librarians and information science experts who will use it to encode their bibliographic metadata.113 gonzales suggests that librarians must be willing to share metadata and upgrade metadata encoding standards to bibframe; they should train, learn, and upgrade their systems to efficiently use bibframe encoding scheme and research new ways of bringing interoperability between bibframe and other legacy metadata standards; and they should ensure the data security of patrons and mitigate the legal and copyright issues in making visible their resources as linked and open data.114 also, lov must be exploited from the cataloging perspective by finding out ways to create a single, flexible, adaptable, and representative vocabulary. such a vocabulary will bring the cataloging data from different https://bibflow.library.ucdavis.edu/about information technology and libraries | december 2018 59 libraries of the world and make it accessible and consumable as a single library linked data to get free from the jungle of metadata vocabularies [and standards]. publishing and consuming linked bibliographic metadata according to the findings of one survey, there are several primary motives for publishing an institution’s [meta]data as linked data. these include (in the order from most frequent/ essential to a lesser one):115 • making data visible on the web; • experimenting and finding the potentials of publishing datasets as linked data; • exposing local datasets to understand the nature of linked data; • exploring the benefits of linked data for search engine optimization (seo); • consuming and reusing linked data in future projects; • increasing the data reusability and interoperability; • testing schema.org and bibframe; • meeting the requirements of the project; and • making available the “stable, integrated, and normalized data about research activities of an institution.”116 they also identified several reasons from the participants regarding the consumption of such data. these include (in the order from most frequent/essential to a lesser one):117 • improving the user experience; • extending local data with other datasets; • effectively managing the internal metadata; • improving the accuracy and scope of search results; • trying to improve seo for local resources; • understanding the effect of data aggregation from multiple datasets; and • experimenting and finding the potentials of consuming linked datasets. publishing and consuming bibliographic data on the lod cloud brings numerous applications. kalou et al. developed a semantic mashup by combining semantic web technologies, restful services, and content management services (cms) to generate personalized book recommendations and publish them as linked data.118 it allows for the expressive reasoning and efficient management of ontologies and has potential applications in the library, cataloging services, and ranking book records and reviews. this application exemplifies how we can use the commercially [and socially] curated metadata with bibliographic descriptions from improved user experience in digital libraries using linked data principles. however, publishing and consuming bibliographic metadata as linked and open data is not that simple and need addressing several prominent challenges and issues, which are identified in the following subsections along with some opportunities for further research. publishing linked bibliographic metadata the university of illinois library worked on publishing marc21 records of 30,000 digitized books as linked library data by adding links, transforming them to lod-friendly semantics (mods) and deploying them as rdf with the objective to be used by a wider community.119 to them, using semantic web technologies, a book can be linked to related resources and multiple possible current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 60 https://doi.org/10.6017/ital.v37i4.10432 contexts, which is an opportunity for libraries to build innovative user-centered services for the dissemination and uses of bibliographic metadata.120 in this regard, the challenge is to utilize the existing book-related bibliographic maximally and descriptive metadata in a manner that parallels with the services (both inside the library and outside) as well as exploit to the fullest the full-text search and semantic web technologies, standards, and lod services.121 while publishing the national bibliographic information as free open linked data, ifla identifies several issues including:122 • dealing with the negative financial impact on the revenue generated from traditional metadata services; • the inability to offer consistent services due to the complexity of copyright and licensing frameworks; • the confusion in understanding the difference between “open” and “free” terms; • remodeling library data as library linked data; • the limited persistence and sustainability of linked data resources; • the steep learning curve in understanding and applying linked data practices to library data; • making choices between sites to link to; and • creating persistent uris for library data objects. from the analysis of the relevant literature, hallo identified several issues in publishing bibliographic metadata as linked and open data. these include difficulties in cataloging and migrating data to new conceptual models; the multiplicity of vocabularies for the same metadata; the lack of agreements to share data; the lack of experts and tools for transforming data; the lack of applications and indicators for its consumption; mapping issues; providing useful links of datasets; defining and controlling data ownership; and ensuring dataset quality.123 libraries should adopt to linked data five-stars model by adopting emerging non-proprietary formats to publish its data; link to external resources and services; participate actively in enriching; and improving the quality of metadata to improve knowledge management and discovery. 124 the cataloging has a bright future with more dataset providers by involving citizens and end -users in metadata enrichment and annotation; making ranking and recommendation as part of library cataloging services; and the increased participation of the library community to the body of semantic web and linked data.125 publishing linked data poses several issues. these include data cleanup issues es pecially when dealing with legacy data; technical issues such as data ownership; the software maturity to keep linked data up-to-date; managing its colossal volume; and providing it support for data entry, annotation, and modeling; developing representative and widely applicable lovs; and handling the steep learning curve to understand and apply linked data principles. 126 bull and quimby stress understanding how the library community is transiting their cataloging methods, systems, standards, and integrations to the lod for making them visible on the web and how they keep backward compatibility with legacy bibliographic metadata.127 it is necessary for the lod data model to maintain the underlying semantics of the existing models, schemas, and standards, yet innovate and renew old traditions, where the quality of the conversion solely depends on the ability of this new model to cope with heterogeneity conflicts, information technology and libraries | december 2018 61 maintain granularity and semantic attributes and consequently prevent loss of data and semantics.128 the new model should be semantically expressive enough to support meaningful and precise linking to other datasets. by thinking alternatively, these challenges are the significant research opportunities that will enable us to be part of linked and open data community in a more profound manner. consuming linked bibliographic metadata consuming linked data resources can be a daunting task and may involve resolving/mitigating several challenges. these challenges include:129 • dealing with the bulky or non-available rdf dumps, no authority control within rdf dumps, and data format variations; • identifying terms’ specificity levels during concept matching; • the limited reusability of library linked data due to lack of contextual data; • harmonizing classes and objects at the institution level; • excessive handcrafting due to few off-the-shelf visualization tools; • manual mapping of vocabularies; • matching, aligning, and disambiguating library and linked data; • the limited representation of several essential resources as linked data due to nonavailability of uris; • the lack of sufficient representative semantics for bibliographic data; • the time-consuming nature of linked data to understand its structure for reuse; • the ambiguity of terms across languages; and • the non-stability of endpoints and outdated datasets. syndication is required to make library data visible on the web. also, it is necessary to understand how current applications including web search engines perceive and treat visibility, to what extent schema.org matters, and what is the nature of the linked data cloud.130 an influential work may be translated into several languages, which results in multiple metadata records. some of these are complete, and others are with missing details. godby and smith‐ yoshimura suggest aggregating these multiple metadata records into a single record, which can be complete, link the work to its different translations and translators, and is publishable (and consumable) as linked data.131 however, such an aggregation demands a great deal of human effort to make these records visible and consumable as linked data. this also includes describing all types of objects that libraries currently collect and manage, translating research findings to best practices; and establishing policies to use uris in marc and other types of records. 132 to achieve the long-term goal of making metadata consumable as linked data; the libraries, as well as individual researchers, should align their research with work that of the major players such as oclc, loc, and ifla and follow their best practices.133 the issues in lov needs immediate attention to make lod more useful. these issues, according to include the following:134 • lov publishes only a subset of rdf vocabularies with no inclusion for value vocabularies such as skos thesaurus; • it provides no or almost negligible support for vocabulary authors; current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 62 https://doi.org/10.6017/ital.v37i4.10432 • it relies on third parties to get the information about vocabulary usage in published datasets; • it has insufficient support for multilingualism or many languages; • it should support multi-term vocabulary search, which is required from the ontology designers to understand and employ the complex relationships among concepts; • it should support vocabulary matching, vocabulary checking, and multilingualism to allow users to search and browse vocabularies using their native language. it also improves the quality of the vocabulary by translation, which allows the community to evaluate and collaborate; and • efforts are required to improve and make possible the long-term preservation of vocabularies. lod emerged to change the design and development of metadata, which has implications for controlled vocabularies, especially, the person/agent vocabularies that are fundamental to data linkage but suffer from the issues of metadata maintenance and verification. 135 therefore, practical data management and the metadata-to-triples transition should be studied in detail to make the wider adaptation of lod possible.136 to come out of the lab environment and make lod practically useful, the controlled vocabularies must be cleaned, and its cost should be reduced.137 however, achieving this is challenging and needs to answer how knowledge artifacts could be uniquely identified and labeled across digital collections and what should be the standard practices to use them.138 linked data is still new to libraries.139 the technological complexities, the feeling of risks in adopting new technology and limitations due to the system, politics, and economy are some of the barriers in its usage in libraries.140 however, libraries can potentially overcome these barriers by learning from the use of linked data in other domains including, e.g., google’s knowledge graph and facebook’s open graph.141 the graph interfaces could be developed to link author, publisher, and book-related information, which in turn can be linked to the other open and freely available datasets.142 it is time that the library and information science professionals come out of the old, document-centric approach to bibliographic metadata and adapt their thinking as more datacentric for a more meaningful consumption of bibliographic metadata by both users and machines.143 quality of linked bibliographic metadata the use of a cataloging data defines its quality.144 the quality is essential for the discovery, usage, provenance, currency, authentication, and administration of metadata. 145 cataloging data or bibliographic metadata is considered fit for use based on its accuracy, completeness, logical consistency, provenance, coherence, timeliness, conformance and accessibility. 146 data is commonly assessed by its quality to be used in specific application scenarios and use cases, however, sometimes, low-quality data can still be useful for a specific application as far as its quality meets the requirements of that application.147 the reasons include several factors including availability, accuracy, believability, completeness, conciseness, consistency, objectivity, relevance, understandability, timeliness, and verifiability that determine the quality of data. 148 the quality of linked data can be of two types, one is the inherent quality of linked data, and the other relates to its infrastructure aspects. the former can be further divided into aspects including domain, metadata, rdf model, links among data items, and vocabulary. the infrastructural information technology and libraries | december 2018 63 aspects include the server that hosts the linked data, linked data fragments, and file servers.149 this typology introduces issues of their own, the issues related to the inherent quality including “linking, vocabulary usage and the provision of administrative metadata.”150 the infrastructural aspect introduces issues related to naming conventions, which include avoiding blank nodes and using http uris, linking through owl:sameas links, describing by reusing the existing terms and dereferencing.151 the quality cataloging definitions are mainly based on the experience and practices of the cataloging community.152 its quality falls into at least four basic categories: (1) the technical details of the bibliographic records, (2) the cataloging standards, (3) the cataloging process, and (4) the impact of cataloging on the user.153 the cataloging community focuses mainly on the quality of bibliographic metadata. however, it is not sufficient enough to consider the accuracy, completeness, and standardization of bibliographic metadata, and therefore, it is necessary that they should also consider the information needs of the users.154 van kleeck et al. investigated issues in the quality management of metadata of electronic resources to assess in supporting user tasks of finding, selecting, and accessing library holdings as well as identifying the potential for increasing efficiencies in acquisition and cataloging workflow.155 they evaluated the quality of existing bibliographic records mostly provided by their vendors and compared them with those of oclc and found that the latter has better support users in resource discovery and access. 156 from the management perspective, the complexity and volume of bibliographic metadata and the method of ingesting it to the catalog emphasize the selection of highest quality records.157 from the perspective of digital repositories, the absence of well-defined theoretical and operational definitions of metadata quality, interoperability, and consistency are some of the issues for the quality of metadata.158 the national information standards organization (niso) identifies several issues in creating metadata. 159 these include the inadequate knowledge about cataloging in both manual and automatic environments leading to inaccurate data entry, inconsistency of subject vocabularies, and limitations of resource discovery, and the development of standardized approaches to structure metadata.160 the poor quality of linked data can make its usefulness much difficult.161 datasets are created at the data level resulting in a significant variance in perspectives and underlying data models.162 this also leads to errors in triplication, syntax, and data; misleading owl:sameas links, and the low availability of sparql endpoints.163 library catalogs, because of their low quality, most often fail to communicate clear and correct information correctly to the users.164 the reasons for such low quality include user’s inability to produce catalogs that are free from faults and duplicates as well as low standards and policies that drive these cataloging practices. 165 although the rich collections of bibliographic metadata are available, these are rich in terms of the heaps of cataloging data and not in terms of quality with almost no bibliographic control. 166 these errors in and the low quality of bibliographic metadata are the result of misunderstanding the aims and functions of bibliographic metadata and adopting the “unwise” cataloging standards and policies.167 still there exist some high-quality cataloging efforts with well-maintained cataloging records, where the only quality warrant is to correctly understand the subject matter of the artifact and effectively communicate between librarians and experts in the corresponding domain knowledge. 168 the demand for such high quality and well-managed catalogs has increased on the web. although current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 64 https://doi.org/10.6017/ital.v37i4.10432 people are more accustomed to web search engines, the quality catalogs will attract not only libraries but the general web users as well (when published and consumed as linked data).169 the community must work together on metadata with publishers and vendors to approach cataloging from the user perspective and refine the skillset as well as produce quality metadata.170 as library and information science professionals, we should not only be the users of the standards , instead, we must actively participate and contribute to its development and improvement so that we may effectively and efficiently connect our data with the rest of the world.171 such collaboration is required from not only the librarians and vendors but also from the users in developing an efficient cataloging environment and for a more usable bibliographic metadata, this is discussed in the next section. linking the socially curated metadata this section addresses rq03 by reviewing the state-of-the-art literature from multiple but related domains including library sciences, information sciences, information retrieval, and semantic web. the section below discusses the importance and possible impact of making socially curated metadata as part of the bibliographic or professionally curated metadata. the next section highlights why social collaborative cataloging approaches should be adopted by librarians to work with other stakeholders in making their bibliographic data available and visible as linked and open data and what is the possible impact of fusing the user-generated content with professional metadata and making it available as linked and open data. the socially curated metadata matters in cataloging conventional libraries have clear and well-established classification and cataloging schemes but these are as challenging to learn, understand, and apply as they are slow and painful to consume.172 using computers to retrieve bibliographic records resulted in the massive usage of copy cataloging.173 however, adopting this practice is challenging, because these records are inconsistent; incomplete; less visible, granular, and discoverable; unable to integrate metadata and content to the corresponding records; difficult to preserve with new and usable format for the consumption by users and machines; and not supportive towards integrating the user-generated content into the cataloging records.174 the university of illinois library, through its vufind service, offers extra features to enhance the search and exploration experience of end users by providing a book’s cover image, table of contents, abstracts, reviews, comments, and user tags.175 users can contribute content such as tags, reviews, comments, and recommend books to friends. h owever, it is necessary to research whether this user-generated content should be integrated to or preserved along the bibliographic records.176 in their book, alemu and stevens mentioned several advantages of making user-generated content as part of the library catalogs.177 these include (i) enhancing the functionality of professionallycurated metadata by making information objects findable and discoverable; (ii) removing the limitations posed by sufficiency and necessity principles of the professionally-curated metadata; (iii) bringing users closer to the library by “pro-actively engaging” them in ratings, tagging, and reviewing, etc., provided that users are also involved in managing and controlling metadata entries; and (iv) the resulting “wisdom of the crowd” would benefit all the stakeholders from this massively growing socially-curated metadata. however, this combination can only be utilized optimally if we can semantically and contextually link it to the internal and external resources; the resulting metadata is openly accessed, shared, and reused; users are supported in easily adding information technology and libraries | december 2018 65 the metadata and made part of the quality control by enabling them to report spamming activities to the metadata experts.178 librarything for libraries (ltfl) makes a library catalog more informative and interactive by enhancing opac, providing access to professional and social metadata, and enabling them to search, browse, and discover library holdings in a more engaging way (https://www.librarything.com/forlibraries). it is one of the practical examples of enriching library catalogs with user-generated content. this trend of merging social and professional metadata innovates library cataloging by dissolving the borders between “social sphere” and library resources.179 the social media has expanded library into social spaces by exploiting tags and tag clouds as navigational tools and enriching the bibliographic descriptions by integrating the user-generated content.180 it bridges the communication gaps between the library and its users, where users take active participation in resource description, discovery, and access. 181 the potential role of the socially curated metadata in resource description, discovery, and access is also evident from the long long-tail social book search research under the initiative for xml retrieval (inex) where both professionally curated bibliographic and user-generated social metadata are exploited for retrieval and recommendation to support both known-item as well as exploratory search.182 by experimenting with amazon/librarything datasets of 2.8 million book records, containing both professional and social metadata, the results conclude that enriching the professional metadata with social metadata especially tags significantly improves search and recommendation.183 koolen also noticed that the social metadata especially tags and reviews significantly improve the search performance as professionally curated metadata is “often too limited” to describe books resourcefully.184 users add socially curated metadata with the intention of making resource re-findable during a future visit, i.e., they add metadata such as tags to facilitate themselves and allow other similar users in resource discovery and access, and therefore, form a community around the resource.185 clements found user tags (social tagging) beneficial for librarians while browsing and exploring the library catalogs.186 to some librarians, tags are complementary to controlled vocabulary; however, training issues and lack of awareness of social tagging functionality in cataloging interfaces prevent their perceived benefit.187 the socially curated metadata as linked data metadata is socially constructed.188 it is shaping and shaped by the context in which it is developed and applied, and demands community-driven approaches, where data should be looked at from a holistic point of view rather than considering them as discrete (individual) semantic units.189 the library is adopting the collaborative social aspect of cataloging that will take place between authors, repository managers, libraries, e-collection consortiums, publishers, and vendors.190 librarians should improve their cataloging skills in line with the advances in technology to expose and make visible their bibliographic metadata as linked and open data.191 currently, linked library data is generated and used by library professionals. socially constructed metadata will act as a value-added in retrieving knowledge artifacts with precision.192 the addition of socially constructed and community-driven metadata in current metadata structures, controlled vocabularies, and classification systems provide the holistic view of these structures as they add the community-generated sense to the professionally-curated metadata structures.193 an https://www.librarything.com/forlibraries current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 66 https://doi.org/10.6017/ital.v37i4.10432 example of the possibilities of making user-generated content as part of cataloging and linked open data is the semantic book mashup (see “consuming linked bibliographic metadata” above) which demonstrates how the commercially [and socially] curated metadata could be retriev ed and linked with bibliographic descriptions.194 while enumerating the possible applications of this mashup, they argue that book reviews from different websites could be aggregated using linked data principles by extending the review class of bibframe 2.0.195 from the analysis of twenty-one in-depth interviews with lis professionals, alemu discovered four metadata principles, namely metadata enrichment, linkage, openness, and filtering.196 this analysis revealed that the absence of socially curated metadata is sub-optimal for the potential of lod in libraries.197 their analysis advocates for a mixed-metadata approach, in which social metadata (tags, ratings, and reviews) augments the bibliographic metadata by involving users proactively and by offering a social collaborative cataloging platform. the metadata principles should be reconceptualized, and linked data should be exploited to address the existing library metadata challenges. therefore, the current efforts in linked data should fully consider social metadata.198 library catalogs should be enriched by mixing the professional and social metadata as well as semantically and contextually interlinked to internal and external information resources to be optimally used in different application scenarios.199 to fully exploit this linkage, the duplication of metadata should be reduced. it must be made openly accessible so that its sharing, reuse, mixing, and matching could be made possible. the enriched metadata must be filtered per user requirements using an interface that is flexible, personalized, contextual, and reconfigurable.200 their analysis suggests a “paradigm shift” in metadata’s future, i.e., from simple to enriched; from disconnected, invisible and locked to well-structured, machine-understandable, interconnected, visible, and more visualized metadata; and from single opac interface to reconfigurable and adaptive metadata interfaces.201 by involving users in the metadata curation process, the mixed approach will bring diversity in metadata and make resources discoverable, usable, and user-centric with the wider and well-supported platform of linked and open data.202 in conclusion, the fusion of socially curated metadata with the standards-based professional metadata is essential from the perspective of the user-centric paradigm of cataloging, which has the potential to aid resource discovery and access and open new opportunities for information scientists working in linked and open data as well as catalogers who are transiting to the web of data to make their metadata visible, reusable, and linkable to other resources on the web. from the analysis and scholarly discussions of alemu, stevens, farnel, and others as well as from the initial experiments of kalou et al.203 it becomes apparent that the application of linked data principles for library catalogs is future-proof and promising towards more user-friendly search and exploration experience with efficient resource description, discovery, access, and recommendations. conclusions in this paper, we presented a brief yet holistic review of the current state of linked and open data in cataloging. the paper identified the potentials of lod and lov in making the bibliographic descriptions publishable, linkable, and consumable on the web. several prominent challenges, issues, and future research avenues were identified and discussed. the potential role of sociallycurated metadata for enriching library catalogs and the collaborative social aspect of cataloging were highlighted. some of the notable points include the following: information technology and libraries | december 2018 67 • publishing, linking, and consuming bibliographic metadata on the web using linked data principles brings several benefits for libraries.204 the library community should improve their skills regarding this paradigm shift and adopt the best practices from other domains.205 • standards have a key role in cataloging, however, we are living in a “jungle of metadata standards” with varying complexity and scale, which makes it difficult to select, apply and work with.206 to be part of global scale activity of making bibliographic data available on the web as linked and open data, these standards should be considered and reenvisioned.207 • the quality of bibliographic metadata depends on several factors including accuracy, completeness, logical consistency, provenance, coherence, timeliness, conformance and accessibility.208 however, achieving these characteristics is challenging because of several reasons including cataloging errors; limited bibliographic control; misunderstanding the role of metadata; and “unwise” cataloging standards and policies.209 to ensure high-quality and make data visible and reusable as linked data, the library community should contribute to developing and refining these standards and policies. 210 • metadata is socially constructed and demands community-driven approaches and the social collaborative aspect of cataloging by involving authors, repository managers, librarians, digital collection consortiums, publishers, vendors, and users.211 this is an emerging trend, which is gradually dissolving the borders between the “social sphere” and library resources and bridging the communication gap between libraries and their users, where end users contribute to the bibliographic descriptions resulting in a diversity of metadata and making it user-centric and usable.212 • adopting a “mixed-metadata approach” by considering bibliographic metadata and the user-generated content complementary and essential for each other suggests a “paradigm shift” in the metadata’s future from simple to enriched; from human-readable data silos to machine understandable, well-structured, and reusable; from invisible and restricted to visible and open; and from single opac to reconfigurable interfaces on the web.213 several researchers including the ones cited in this article agree that the professionally curated bibliographic metadata supports mostly the known-item search and has little value to open and exploratory search and browsing. they believe that not only the collaborative social efforts of the cataloging community are essential but also the socially curated metadata, which can be used to enrich bibliographic metadata and support exploration and serendipity. this is not only evident from the wider usage of librarything and its ltfl but also from the long-tail inex social book search research where both professionally curated bibliographic and user-generated social metadata are exploited for retrieval and recommendation to support both known-item as well as exploratory search.214 therefore, this aspect should be considered for further research to make cataloging more useful for all the stakeholders including libraries, users, authors, publishers, and for the general consumption as linked data on the web. the current trend of social collaborative cataloging efforts is essential to fully exploit the potential of linked open data. however, if we look closely, we find four groups including librarians, linked data experts, information retrieval (ir) and interactive ir researchers; and users, all going on their separate ways with minimal collaboration and communication. more specifically, they are not benefiting from each other to a greater extent, which could result in better possibilities of current state of linked and open data in cataloging | ullah, khusro, ullah, and naeem 68 https://doi.org/10.6017/ital.v37i4.10432 resource description, discovery, and access. for example, the library community should consider the findings of inex sbs track, which have demonstrated that professional and social metadata, are essential for each other to facilitate end users in resource discovery and access and support not only known-item search but also exploration and serendipity. the current practices of librarything, ltfl, and social web in general advocate for user-centric cataloging, where users are not only the consumers of bibliographic descriptions but also the contributors to metadata enrichment. linked open data experts have achieved significant milestones in other domains including, e.g., e-government, they should understand the cataloging and resource discovery & access practices in libraries to make the bibliographic metadata not only visible as linked data on the web but also shareable, re-usable, and beneficial to the end-users. the social collaborative cataloging approach by involving the four mentioned groups actively is significant to make bibliographic descriptions more useful not only for the library community and users but also for their consumption on the web as linked and open data. together we can, and we must. references 1 maría hallo et al., “current state of linked

2019) letter from the editor kenneth j. varnum information technology and libraries | december 2019 1 https://doi.org/10.6017/ital.v38i4.11923 earlier this fall, i had the privilege of participating in the sharjah library conference, a three-day event hosted by the sharjah book authority in the united arab emirates with programming coordinated by the ala international relations office. the experience of meeting with so many librarians from cultures different from my own was truly rewarding and enriching. it was both refreshing and invigorating to see, first-hand, the global importance of the local matters that occupy so much of my professional life. i returned to my regular job with a newfound appreciation for how much the issues i spend so much of my professional time on—information access, equity, user experience, and the like—are universal. it is easy to get lost in the weeds of my own circumstances and environment, and sometimes difficult to look up and explore what colleagues, known and unknown, are doing and thinking. the experience reinforces the importance of important open access publications such as information technology and libraries. while “open access” doesn’t remove every possible barrier to accessing the knowledge, experience, and lessons contained within in its virtual cover, it does remove the all-important paywall. and that is no small thing, in a community of library technologists who interact and exchange information through social media, email, and other tools. our open access status gives this journal a vibrant platform for sharing knowledge, experience, and expertise to all who seek it. i hope you find this issue’s contents useful and informative, and will share the items you find most important with your peers at your institutions and beyond. i invite you to add your own knowledge and experience to our collective wisdom through a contribution to the journal. for more details, see the about the journal page or get

zarazaga-soria 39 author id box for 2 column layout knowledge organization systems denotes formally represented knowledge that is used within the context of digital libraries to improve data sharing and information retrieval. to increase their use, and to reuse them when possible, it is vital to manage them adequately and to provide them in a standard interchange format. simple knowledge organization systems (skos) seem to be the most promising representation for the type of knowledge models used in digital libraries, but there is a lack of tools that are able to properly manage it. this work presents a tool that fills this gap, facilitating their use in different environments and using skos as an interchange format. u nlike the largely unstructured information avail­ able on the web, information in digital libraries (dls) is explicitly organized, described, and man­ aged. in order to facilitate discovery and access, dl sys­ tems summarize the content of their data resources into small descriptions, usually called metadata, which can be either introduced manually or automatically generated (index terms automatically extracted from a collection of documents). most dls use structured metadata in accor­ dance with recognized standards, such as marc21 (u.s. library of congress 2004) or dublin core (iso 2003). in order to provide accurate metadata without ter­ minological dispersion, metadata creators use different forms of controlled vocabularies to fill the content of typi­ cal keyword sections. this increase of homogeneity in the descriptions is intended to improve the results provided by search systems. to facilitate the retrieval process, the same vocabularies used to create the descriptions are usu­ ally used to simplify the construction of user queries. as there are many different schemas for modeling controlled vocabularies, the term knowledge organization systems (kos) is intended to encompass all types of schemas for organizing information and promoting knowledge management. as hodge (2000) says, “a kos serves as a bridge between the users’ information need and the material in the collection.” some types of kos can be highlighted. examples of simple types are glossaries, which are only a list of terms (usually with definitions), and authority files that control variant ver­ sions of key information (such as geographic or personal names). more complex are subject headings, classifica­ tion schemes, and categorization schemes (also known as taxonomies) that provide a limited hierarchical structure. at a more complex level, kos includes thesauri and less traditional schemes, such as semantic networks and ontologies, that provide richer semantic relations. there is not a single kos on which everyone agrees. as lesk (1997) notes, while a single kos would be advantageous, it is unlikely that such a system will ever be developed. culture constrains the knowledge classifi­ cation scheme because what is meaningful to one area is not necessarily meaningful to another. depending on the situation, the use of one or another kos has its advan­ tages and disadvantages, each one having its place. these schemas, although sharing many characteristics, usually have been treated heterogeneously, leading to a variety of representation formats to store them. thesauri are an example of the format heterogeneity problem. according to iso­2788 (norm for monolingual thesauri) (iso 1986), a thesaurus is a set of terms that describe the vocabulary of a controlled indexing language, formally organized so that the a priori relationships between con­ cepts (for example, synonyms, broader terms, narrower terms, and related terms) are made explicit. this stan­ dard is complemented with iso­5964 (iso 1985), which describes the model for multilingual thesauri, but none of them describe a representation format. the lack of a stan­ dard representation model has caused a proliferation of incompatible formats created by different organizations. so each organization that wants to use several external thesauri has to create specific tools to transform all of them to the same format. in order to eliminate the heterogeneity of represen­ tation formats, the w3c initiative has promoted the development of simple knowledge organization systems (skos) (miles et al. 2005) for its use in the semantic web environment. skos has been created to represent simple kos, such as subject heading lists, taxonomies, classifica­ tion schemes, thesauri, folksonomies, and other types of controlled vocabulary as well as concept schemes embed­ ded in glossaries and terminologies. although skos has been recently proposed, the number and importance of organizations involved in its creation process (and that publish their kos in this format) indicates that it will probably become a standard for kos representation. skos provides a rich, machine­readable language that is very useful to represent kos, but nobody would expect to have to create it manually or by just using a general­purpose resource description framework (rdf) editor (skos is rdf­based). however, in the digital library area, there are not specialized tools that are able to manage it adequately. therefore, this work tries to fill this gap, describing an open source tool, thmanager, that thmanager: an open source tool for creating and visualizing skos javier lacasta, javier nogueras-iso, francisco javier lópez-pellicer, pedro rafael muro-medrano, and francisco javier zarazaga-soria javier lacasta (jlacasta@unizar.es) is

information technology and libraries | september 2007�0 information technology and libraries | september 2007 facilitates the construction of skos­based kos. although thmanager has been created to manage thesauri, it also is appropriate to create and manage any other models that can be represented using skos format. this article describes the thmanager tool, highlight­ ing its characteristics. thmanager’s layer­based architec­ ture permits the reuse of the components created for the management of thesauri in other applications where they are also needed. for example, it facilitates the selection of values from a controlled vocabulary in a metadata cre­ ation tool, or the construction of user queries in a search client. the tool is distributed as open source software accessible through the sourceforge platform (http:// thmanager.sourceforge.net/). ■ state of the art in thesaurus tools and representation models the problem of creating appropriate content for thesauri is of interest in the dl field and other related disciplines, and an increasing number of software packages have appeared in recent years for constructing thesauri. for instance, the web site of willpower information (http://www .willpower.demon.co.uk/thessoft.htm) offers a detailed revision of more than forty tools. some are only avail­ able as a module of a complete information storage and retrieval system, but others also allow the possibility of working independently of any other software. among these thesaurus creation tools, one may note the follow­ ing products: ■ bibliotech (http://www.inmagic.com/). this is a multiplatform tool that forms part of bibliotech pro integrated library system and can be used to build an ansi/niso standard thesaurus (standard z39.19 [ansi 1993]). ■ lexico (http://www.pmei.com/lexico.html). this is a java­based tool that can be accessed and/or manip­ ulated over the internet. thesauri are saved in a text­based format. it has been used by the u.s. library of congress to manage such vocabularies and thesauri as the thesaurus for graphic materials, the global legal information network thesaurus, the legislative indexing vocabulary, and the symbols of american libraries listing. ■ multites (http://www.multites.com/) is a windows­ based tool that provides support for ansi/niso relationships plus user­defined relationships and comment fields for an unlimited number of thesauri (both monolingual and multilingual). ■ termtree 2000 (http://www.termtree.com.au/) is a windows­based tool that uses access, sql server, or oracle for data storage. it can import and export trim thesauri (a format used by the towers records information management system [http://www.towersoft.com/]), as well as a defined termtree 2000 tag format. ■ webchoir (http://www.webchoir.com/) is a family of client­server web applications that provides dif­ ferent utilities for thesaurus management in multiple dbms platforms. termchoir is a hierarchical infor­ mation organizing and searching tool that enables one to create and search varieties of hierarchical subject categories, controlled vocabularies, and tax­ onomies based on either predefined standards or a user­defined structure, and is then exported to an xml­based format. linkchoir is another tool that allows indexers to describe information sources using terminology organized in termchoir. and seekchoir is a retrieval system that enables users to browse thesaurus descriptors and their references (broader terms, related terms, synonyms, and so on). ■ synaptica (http://www.synaptica.com/) is a client­ server web application that can be installed locally on a client’s intranet or extranet server. thesaurus data is stored in a sql server or oracle database. the application supports the creation of electronic the­ sauri in compliance with the ansi/niso standard. the application allows the exchange of thesauri in csv (comma­separated values) text format. ■ superthes (batschi et al. 2002) is a windows­based tool that allows the creation of thesauri. it extends the ansi/niso relationships, allowing many pos­ sible data types to enrich the properties of a concept. it can import and export thesauri in xml and tabular format. ■ tematres (hhttp://r020.com.ar/tematres/) is a web application specially oriented to the creation of thesauri, but it also can be used to develop web navigation structures or to manage the documentary languages in use. the thesauri are stored in a mysql database. it provides the created thesauri in zthes (tylor 2004) or in skos format. finally, it must be mentioned that, given that thesauri can be considered as ontologies specialized in organiz­ ing terminology (gonzalo et al. 1998), ontology editors have sometimes been used for thesaurus construction. a detailed survey of ontology editors can be found in the denny study (2002). all of these tools (desktop or web­based) present some problems in using them as general thesaurus editors. the main one is the incompatibility in the interchange formats that they support. these tools also present integration problems. some are deeply integrated in bigger sys­ tems and cannot easily be reused in other environments because they need specific software components to work article title | author �1thmanager | lacasta, nogueras-iso, lópez-pellicer, muro-medrano, and zarazaga-soria �1 (as dbms to store thesauri). others are independent tools (can be considered as general­purpose thesaurus editors), but their architecture does not facilitate their integration within other information management tools. and most of them are not open source tools, so there is no possibility to modify them to improve their functionality. focusing on the interchange format problem, the iso­5964 standard (norm for multilingual thesauri) is currently undergoing review by iso tc46/sc 9, and it is expected that the new modifications will include a stan­ dard exchange format for thesauri. it is believed that this format will be based on technologies such as rdf/xml. in fact, some initiatives in this direction have already arisen: ■ the adl thesaurus protocol (janée et al. 2003) defines an xml­ and http­based protocol for access­ ing thesauri. as a result of query operations, portions of the thesaurus encoded in xml are returned. ■ the language independent metadata browsing of european resources (limber) project has published a thesaurus interchange format in rdf (matthews et al. 2001). this work introduces an rdf representa­ tion of thesauri, which is proposed as a candidate thesaurus interchange format. ■ the california environmental resources evaluation system (ceres) and the nbii biological resources division are collaborating in a thesaurus partnership project (ceres/nbii 2003) for the development of an integrated environmental thesaurus and a thesau­ rus networking toolset for metadata development and keyword searching. one of the deliverables of this project is an rdf format to represent thesauri. ■ the semantic web advanced development for europe (swad­europe 2001) project includes the swad­europe thesaurus activity, which has defined the skos, a set of specifications to represent the knowledge organization systems (kos) on the semantic web (thesauri between them). the british standards bs­5723 (bsi 1987) and bs­6723 (bsi 1985) (equivalent to the international iso­2788 and iso­5964) also lack a representation format. the british standards institute idt/2/2 working group is now developing the bs­8723 standard that will replace them and whose fifth part will describe the exchange formats and protocols for interoperability of thesauri. the objec­ tive of this working group is to promote the standard to iso, to replace the iso­2788 and iso­5964. here, it is important to remark that given the direct involvement of the idt/2/2 working group with skos development; probably the two initiatives will not diverge. the new representation format will be, if not exactly skos, at least skos­based. taking into account all these circumstances, skos seems to be the most adequate representation model to store thesauri. given that skos is rdf­based, it can be created using any tool that is able to manage rdf (usually used to edit ontologies); for example, swoop (mindswap group 2006), protégé (noy et al. 2000), or triple20 (wielemaker et al. 2005). the problem with these tools is that they are too complex for editing and visualizing such a simple model as skos. they are thought to create complex ontologies, so they provide too many options not spe­ cifically adapted to the type of relations in skos. in addition, they do not allow an integrated management of collection of thesauri and other types of controlled vocabularies as needed in dl processes (for example, the creation of metadata of resources, or the construction of queries in a search system). ■ skos model skos is a representation model for simple knowledge organization systems, such as subject heading lists, tax­ onomies, classification schemes, thesauri, folksonomies, other types of controlled vocabulary, and also concept schemes embedded in glossaries and terminologies. this section describes the model, providing characteristics, showing the state of development, and indicating the problems found to represent some types of kos. skos was initially developed within the scope of the semantic web advanced development for europe (swad­europe 2001). swad­e was created to support w3c’s semantic web initiative in europe (part of the ist­7 programme). skos is based on a generic rdf schema for thesauri that was initially produced by the desire project (cross et al. 2001), and further developed in the limber project (matthews et al. 2001). it has been developed as a draft of an rdf schema for thesauri com­ patible with relevant iso standards, and later adapted to support other types of kos. among the kos already published using this new format are gemet (eea 2001), agrovoc (fao 2006), adl feature types (hill and zheng 1999), and some parts of wordnet lexical data­ base (miller 1990), all of them available on the skos project web page. skos is a collection of three different rdf schema application profiles: skos­core, to store common prop­ erties and relations; skos­mapping, whose purpose is to describe relations between different kos; and skos­ extension, to indicate specific relations and properties only contained in some type of kos. for the first step of the development of the thmanager tool, only the most stable part of skos has been consid­ ered. figure 1 shows the part of skos­core used. the rest of skos­core is still unstable, so its support has been delayed until it is approved. skos­mapping and skos­extension are still in their first steps of develop­ �2 information technology and libraries | september 2007�2 information technology and libraries | september 2007 ment and are very unstable, so their management in thmanager also has been delayed until the creation of stable versions. in skos­core, a kos (in our case, usually a the­ saurus) consists of a set of concepts (labelled as skos: concept) that are grouped by a concept scheme (skos: conceptscheme). to distinguish between different mod­ els provided, the skos:conceptscheme contains a uri that identifies it, but to describe the model content to humans, metadata following the dublin core standard also can be added. the relation of the concept scheme with the concepts of the kos is done through the skos: hastopconcept relation. this relation points at the most general concepts of the kos (top concepts), which are used as entry points to the kos structure. in skos, each concept consists of a uri and a set of properties and relations to other concepts. among the properties, skos.preflabel and skos.altlabel provide labels for a concept in different languages. the first one is used to show the label that better identifies a concept (for the­ sauri it must be unique). the second one is an alternative label that contains synonyms or spelling variations of the preferred label (it is used to redirect to the preferred label of the concept). the skos concepts also can contain three other properties called skos.scopenote, skos.definition, and skos.example. they contain annotations about the ways to use a concept, a definition, or examples of use in differ­ ent languages. last, the skos.prefsymbol and skos.altsymbol properties are used to provide a preferred or some alter­ native symbols that graphically represent the concept. for example, a graphical representation is very useful to identify the meaning of a mathematical formula. another example is a chemical formula, where a graphical repre­ sentation of the structure of the substance also provides valuable information to the user. with respect to the relations, each concept indicates by means of the skos:inscheme relation in which concept scheme it is contained. the skos.broader and the skos.narrower relations are inverse relations used to model the generalization and specialization characteristics present in many kos (including thesauri). skos.broader relates to more general concepts, and skos.narrower to more spe­ cific ones. the skos.related relation describes associative relationships between concepts (also present in many thesauri), indicating that two concepts are related in some way. with these properties and relations, it is perfectly possible to represent thesauri, taxonomies, and other types of controlled vocabularies. however, there is a problem for the representation of classification schemes that provide multiple coding of terms, as there is no place to store this information. under this category, one may find classification schemes such as iso­639 (iso 2002) (iso standard for coding of languages), which proposes different types of alphanumeric codes (for example, two letters and three letters). for this special case, the skos working group proposes the use of the property skos.notation. although this property is not in the skos vocabulary yet, it is expected to be added in future versions. given the need to work with these types of schemes, this property has been included in the thmanager tool. ■ thmanager architecture this section presents the architecture of thmanager tool. this tool has been created to manage thesauri in skos, but it also is a base infrastructure that facilitates the management of thesauri in dls, simplifying their inte­ gration in tools that need to use thesauri or other types of controlled vocabularies. in addition, to facilitate its use on different computer platforms, thmanager has been developed using the java object­oriented language. the architecture of thmanager tool is shown in figure 2. the system consists of three layers: first, a repository layer where thesauri are stored and identified by means of associated metadata describing them; second, a per­ sistence layer that provides an api for access to thesauri stored in the repository; and third, a gui layer that offers different graphical components to visualize thesauri, to search by their properties, and to edit them in different ways. the thmanager tool is an application that uses the different components provided by the gui layer to allow the user to manage the thesauri. in addition, the layered architecture allows other applications to use some of the visualization components or the method provided by the persistence layer to provide access to thesauri. the main features that have guided the design of these layers have been the following: a metadata­driven design, efficient management of thesauri, the possibility of interrelating thesauri, and the reusability of thmanager figure 1. skos model article title | author �3thmanager | lacasta, nogueras-iso, lópez-pellicer, muro-medrano, and zarazaga-soria �3 components. the following subsections describe these characteristics in detail. metadata-driven design a fundamental aspect in the repository layer is the use of metadata to describe thesauri. thmanager considers metadata of thesauri as basic information in the thesau­ rus management process, being stored in the metadata repository and managed by the metadata manager. the reason for this metadata­driven design is that thesauri must be described and classified to facilitate the selec­ tion of the one that better fits the user needs, allowing the user to search them not only by their name but also by the application domain or the associated geographi­ cal area between others. the lack of metadata makes the identification of useful thesauri (provided by other organizations) difficult, producing a low reuse of them in other contexts. to describe thesauri in our service, a metadata profile based on dublin core has been created. the reason to use dublin core as basis of this profile has been its extensive use in the metadata community. it provides a simple way to describe a resource using very general metadata ele­ ments, which can be easily matched with complex domain­ specific metadata standards. additionally, dublin core also can be extended to define application profiles for specific types of resources. following the metadata pro­ file hierarchy described in tolosana­calasanz et al. (2006), the thesaurus metadata profile refines the definition and domain of dublin core elements as well as includes two new elements (metadata language and metadata identifier) to appropriately identify the metadata records describing a thesaurus. the profile for thesauri has been described using the iemsr format (heery et al. 2005) and is distributed with the tool. iemsr is an rdf­based format created by the jisc ie metadata schema registry project to describe metadata application profiles. figure 3 shows the metadata created for gemet thesaurus (the resource), expressed as a hedgehog graph (reinterpreta­ tion of rdf triplets: resources, named properties, and values). the purpose of these metadata is not only to sim­ plify the thesaurus location to a user, but also to facilitate the identification of thesauri useful for a specific task in a machine­to­machine communication. for instance, one may be interested only in thesauri that cover a restricted geographical area or have a specific thematic. efficient thesauri storage thesauri vary enormously in size, ranging from hundreds of concepts and properties to millions. so the time spent on load, navigation, and search processes are a functional restriction for a tool that has to manage them. skos is rdf­based, and because reading rdf to extract the con­ tent is a slow process, the format is not appropriate for inner storage. to provide better access time, thmanager transforms skos into a binary format when a new skos is imported. the persistence layer provides a unified access to the thesaurus repository. this layer is used by the gui layer figure 2. kos manager architecture viewer generatorviewer generator repository concept repository metadata manager concept manager persistence gui

web that requires browsing a thesaurus to facilitate construction of user queries). this layer performs the transformation of skos to the binary format when a thesaurus is imported. the transformation is provided using the jena library, a popular library to manipulate rdf documents that allows storing them in different kinds of repositories (http://jena.sourceforge. net/). jena provides an open model that can be extended with specialized modules to use other ways of storage, making it possible to easily change the storage format system for another that is more efficient if needed. the data structure used is shown in figure 4. the model is an optimized representation of the information given by the rdf triplets. the concepts map contains the concepts and their associated relations in the form of key­value pairs: the key is a uri identifying a concept; and the value is a relations object containing the properties of the concept. a relations object is a map that stores the properties of one concept in the form of <property type, property values> pairs. the keys used for this map are the names of the typical property types in the skos model (for example, narrower or broader). the only special cases for encoding these property types in the proposed data structure occur when they have a language attribute (for example, preflabel, definition, or scopenote). in those cases, we propose the use of a [lang] suffix to distinguish the property type for a particular language. for instance, preflabel_en indicates a preflabel property type in english. additionally, it must be noted that the data type of the property values assigned to each key in the relations map varies upon the semantics given to each property type. the data types fall into the following categories: a string for a preflabel property type; a list of strings for altlabel, definition, scope note, and example property types; a uri for a prefsymbol property type; a list of uris for narrower, broader, related, and altsymbol property types; and a list of notation objects for a notation property type. the data type used for notation values is a complex object because there may be different notation types. a notation object consists of type and value attributes. the type attribute is a uri that identifies a particular notation type and qualifies the associated notation value. additionally, and with the objective of increasing the speed of some operations (for example, navigation or search), some optimizations have been added. first, the uris of the top concepts are stored in the topconcepts list. this list contains redundant information, given that those concepts also are stored in the concepts map, but it makes immediate their location. second, to speed up the search of concepts and the drawing of the alphabetic viewer, the translations map has been added. for each language sup­ ported by the thesaurus, this map contains a translationterm object, or list of pairs <uri, preflabel>, ordered by preflabel. it also contains redundant information that allows the immediate creation of the alphabetic viewer for a language, simplifying the search process; as can be seen later, this does not provides a big over­ head in load time. in addition, if no alphabetic viewer and search are needed, this structure can be removed without affecting the hierarchical viewer. this solution has proven to be useful to manage the kind of thesauri we use (they do not sur­ pass 50,000 concepts and about 330,000 properties), loading them to memory in an average com­ puter in a reasonable time, and allowing immediate navigation and search (see section 6). interrelation of thesauri the vast choice of thesauri that are available nowadays implies an undesired effect of content heterogeneity.

knowing the connections of a thesaurus in their application domain to thesauri used in other domains. however, it is difficult to manually detect the implicit links between those different thesauri. therefore, in order to automatically facilitate these interthesaurus connections, the persistence layer of thmanager tool provides an interrelation function that relates a thesaurus with respect to an upper­level lexical database (the concept core displayed in figure 2). the interrelation mechanism is based on the method presented in nogueras­iso, zarazaga­soria, and muro­ medrano (2005). it is an unsupervised disambiguation method that uses the relations between concepts as disam­ biguation context. it applies a heuristic voting algorithm to select the most adequate sense of the used concept core for each thesaurus concept. at the moment, the concept core is the wordnet lexical database. wordnet is a large english lexical database that groups nouns, verbs, adjectives, and adverbs into sets of cognitive synonyms (synsets), each expressing a distinct concept. those synsets are interlinked by means of conceptual­semantic and lexical relations. the interrelation component has been conceived as an independent module that receives a thesaurus as input in skos and returns the relation respect to concept core using an extended version of the skos mapping model (miles and brickley 2004). this model, as commented before, is a part of skos that allows describing exact, major, and minor mappings between concepts of two different kos (in this case between a thesaurus and the common core). skos mapping is still in an early stage of development and has been extended in order to provide the needed functionality. the base skos mapping provides the map:exactmatch, map:majormatch, and map:minormatch relations to indicate the degree of relation between two concepts. given that the interrelation algorithm cannot ensure that a mapping is 100 percent exact, only the major and minor match properties are used. the algorithm returns a list of pos­ sible mappings with the lexical database for each concept: the one with the highest probability is assigned as major match, and the rest are assigned as minor matches. to store the interrelation probability, skos mapping has been extended by adding a blank node with the liability of the mapping. also, to be able to know which concepts of which thesauri are equivalents to one of the common core, the inverse relations of map:majormatch and map:minormatch have been created. an example of skos mapping can be seen in figure 5. there, the concept 340 of gemet thesaurus (alloy) is correctly mapped to the wordnet concept number 13751474 (alloy, metal) with a probability of 91.007 percent, an unrelated minor mapping also is found, but it is given a low probability (8.992 percent). reusability of thmanager components on top of the api layer, the gui layer has been con­ structed. this layer contains several graphical interfaces to provide different types of viewers, searchers, and edi­ tors for thesauri. this layer is used as base for the con­ struction of the thmanager tool. the tool groups a subset of the provided components, relating them to obtain a final user application that allows the management of the stored thesauri, their visualization (navigation by the concept relations), their edition, and their importation and exportation using skos format. the thmanager tool not only has been created as an independent tool to facilitate thesauri management, but also to allow easy integration in tools that need to use thesauri. it has been done by combining the informa­ tion management with specific graphical interfaces in different black­box components. between the provided components, there is a hierarchical viewer, an alphabetic viewer, a list viewer, a searcher, and an editor, but more components can be constructed if needed. the use of the gui layer as a library of reusable graphical components makes it possible to create different tools that are able to manage thesauri with different user requirements with minimum effort, allowing also the integration of this technology in other applications that need controlled vocabularies to improve their functionality. for example, in a metadata creation tool, it can be used to provide the graphical component to select controlled values from thesauri and automatically insert them in the metadata. it also can be used to provide the list of possible values to use in a web search system, or to provide a thesaurus­ based navigation of a collection of resources in an explor­ atory search system. figure 6 shows the integration process of a thesau­ rus visualization component in an external tool. the provided thesaurus components have been constructed following the java beans philosophy (reusable software components that can be manipulated visually in a builder tool), where a component is a black box with methods to read and change its state that can be reused when needed. here, each thesaurus component is a thesaurusbean that can be directly inserted in a graphical application to use its functionality (visualize or edit thesauri) in a very simple way. the thesaurusbeans are provided by the thesaurusbeanmanager that, given the parameters of the thesaurus to visualize and the type of visualization, returns the most adequate component to use. ■ description of thmanager functionality thmanager tool is a desktop application that is able to manage thesauri stored in skos. as regards to the instal­ �6 information technology and libraries | september 2007�6 information technology and libraries | september 2007 lation requirements, the application requires 100 mbs of free space on the hard disk. with respect to ram and cpu requirements, they depend greatly on the size and the number of thesauri loaded in the tool. considering the number and size of thesauri used as testbed in section 6, ram consumption ranges from 256 to 512 mbs, and with a 3ghz cpu (for example, pentium iv), the load times for the bigger thesauri are acceptable. however, if the size of thesauri is smaller, ram and cpu requirements decrease, being able to operate on a computer with just a 1 ghz cpu (for example, pentium iii) and 128 mbs of ram. given that the management of thmanager is meta­ data oriented, the first window in the application shows a table including the metadata records describing all the thesauri stored in the system (figure 7). the selection of a record in this table indicates to the rest of the compo­ nents the selected thesaurus. the creation or deletion of thesauri also is provided here. the only operation that can be performed when no record is selected is to import a new thesaurus stored in skos. to import it, the name of the skos file must be provided. the import tool also contains the option to interrelate the imported thesaurus to the concept core. the metadata of the thesaurus are extracted from inside of the skos if they are available, or they can be provided in an associated xml metadata file. if no metadata record is provided, the application generates a new one with minimum information, using as base the name of the skos file. once the user has selected a thesaurus, it can visualize and modify its metadata or content, export it to skos, or, as commented before, delete it. with respect to the metadata describing a thesaurus, a metadata viewer visualizes the metadata in html and a metadata editor allows the editing of metadata following the thesaurus metadata profile described in the metadata­driven design section (figure 8 shows a screenshot of the metadata edi­ tor). different html views can be provided by adding more css files to the application. the metadata editor is customiz­ able. to add or delete metadata elements to the metadata edi­ tor window, it is only neces­ sary to modify the description of the iemsr profile for thesauri included in the application. the main functionality of the tool is to visualize the thesaurus structure, showing all proper­ ties of concepts and allowing the navigation by relations (see figure 9). here, different read­only viewers are provided. there is an alphabetic viewer that shows all the concepts ordered by the preferred label in one language. a hierar­ chical viewer provides navigation by broader and nar­ rower relations. additionally, a hypertext viewer shows all properties of a concept and provides navigation by all its relations (broader, narrower, and related) via hyper­ links. finally, there also is a search system that allows the typical searches needed for thesauri (equals, starts with, contains). currently, search is limited to preferred labels in the selected language, but it could be extended to allow searches by other properties, such as synonyms, defini­ tions, or scope notes. figure 5. skos mapping extension <rdf:description rdf:about="http://www.eionet.eu.int/gemet/concept/340"> <rdf:type

nogueras-iso, lópez-pellicer, muro-medrano, and zarazaga-soria �7 all of these viewers are synchronized, so the selec­ tion of a concept in one of them produces the selection of the same concept in the others. the layered architec­ ture described previously allows these viewers to be reused in many situations, including other parts of the thmanager tool. for example, in the thesaurus metadata editor described before, the thesaurus viewer is used to facilitate the selection of values for the subject section of metadata. also, in the thesaurus editor shown later, the thesaurus viewer simplifies the selection of a concept related (by some kind of relation) to the selected, and provides a preview of the hierarchical viewer to help to detect wrong relations. the third available operation is to edit the thesaurus structure. here, to create a thesaurus following the skos model, an edition component is provided (see figure 10). the graphical interface shows a list with all the concepts created in the selected thesaurus, allowing the creation of new ones (providing their uris) or deletion of selected ones. once a concept has been selected, its properties and relations to other concepts are shown, allowing the creation of new ones and the deletion of others. to facili­ tate the creation of relations between concepts, a selector of concepts (based in the thesaurus viewer) is provided, allowing the user to add related concepts without manu­ ally typing the uri of the associated concept. also, to see if the created thesaurus is correct, a preview of the hier­ archical viewer can be shown, allowing the user to easily detect problems in the broader and narrower relations. with respect to the interrelation functionality, at the moment the mapping obtained is shown in the thesaurus viewers, but the navigation between equivalent concepts of two thesauri must be be done manually by the user. however, a navigation component still under develop­ ment will allow the user to jump from a concept in a the­ saurus to concepts in others that are mapped to the same concept in the common core. as mentioned before, for efficiency, the format used to store the thesauri in the repository is binary, but the inter­ change format used is skos. so a module for thesauri importation and exportation is provided. this module is able to import from and export to skos. in addition, if the thesaurus has been interrelated with respect to the concept core, it is able to export its mapping to the con­ cept core using the extended version of skos mapping above. ■ results of the work this section shows some experiments performed with the thmanager tool for the storage and management of a selected set of thesauri. in particular, this set of thesauri is relevant in the context of the geographic information community. the increasing relevance of geographic infor­ mation for decision­making and resource management in different areas of government has promoted the cre­ ation of geo­libraries and spatial data infrastructures to facilitate distribution and access of geographic informa­ tion (nogueras­iso, zarazaga­soria, and muro­medrano, 2005). in this context, complex metadata schemes, such as iso­19115, have been proposed for a full­detail descrip­ tion of resources. many of the metadata elements in these schemes are either constrained to a selected vocabulary (iso­639 for language encoding, iso­3166 for country codes, and so on), or the user is told to pick a term from the most suitable thesaurus. the problems with this sec­ ond case are that typically the choice for thesauri is quite open, the thesauri are frequently large, and the exchange format of available thesauri is quite heterogeneous. in such a context, the thmanager tool has proven to be very useful to simplify the management of the used thesauri. at the moment, eighty kos between thesauri and other types of controlled vocabulary have been cre­ ated or transformed to skos and managed through this tool. table 1 shows some of them, indicating their names (name column), the number of concepts (nc column), their total number of properties and relations (np and nr columns), and the number of languages in which concept properties are provided (nl column). to give an idea of the cost of loading these structures, the sizes of skos and binary files (ss and sb columns) are provided in kilobytes (kb). additionally, table 1 compares the performance time of thmanager with respect to other tools that load the figure 7. thesaurus selector figure �. thesaurus metadata editor �� information technology and libraries | september 2007�� information technology and libraries | september 2007 thesauri directly from an rdf file using the jena library (time performance has been obtained using a 3ghz pentium iv processor). for this purpose, three different load times (in seconds) have been computed. the bt column contains the load time of binary files without the cost of creating the gui for the thesauri viewers. the lt column contains the total load time of binary files (including the time of gui creation and drawing). the jt column contains the time spent by a hypothetical rdf­ based editor tool to invoke jena and load in its memory model the rdf skos files (it does not include gui cre­ ation) containing the thesauri. the difference between the bt and lt column shows the time used to draw the gui once the thesauri have been loaded in memory. the difference between bt and jt columns shows the gain in terms of time of using a binary storage instead of a rdf based one. the thesauri shown in the table are the adl feature types thesaurus (adl ftt), the isoc thesaurus of geography (isoc­g), the iso­639, the unesco thesaurus (unesco 1995), the ogp surveying and positioning committee code lists (epsg) (ogp 2006), the multilingual agricultural thesaurus (agrovoc), the european vocabulary thesaurus (eurovoc) (eupo 2005), the european territorial units (spain and france) (etu), and the general multilingual environmental thesaurus (gemet). they have been selected because they have different sizes and can be used to show how the load time evolves with the thesaurus size. among them, gemet and agrovoc can be high­ lighted. although they are provided as skos, they include nonstandard extensions that we have transformed to standard skos relations and properties. eurovoc and unesco are examples of thesauri provided in formats different than skos that we have completely transformed into skos. the former one was in an xml­based format, and the latter used a plain­text format. another thesaurus transformed to skos is the european territorial units, which contains the administrative political units in spain and france. here, the original source was a collection of heterogeneous documents that contained parts of the needed information and have been processed to generate a skos file. some classification schemes also have been trans­ formed to skos, such as the iso­639 and the different epsg codes for coordinate reference systems (includ­ ing datums, ellipsoids, and projections). with respect to controlled vocabularies created (by the authors) in skos using the thmanager tool, there is an extended version of the adl feature types that includes a more detailed clas­ sification of features types and different glossaries used for resource classification. figure 11 depicts the comparison of the different load times shown in table 1 with respect to the size of the rdf skos files. the order of the thesauri in the figure is the same as in the table 1. it can be seen that the time to con­ struct the model using a binary format is almost half the time spent to create the model using a rdf file. in addi­ tion, once the binary model is loaded, the time to generate the gui is not very dependent on thesaurus size. this is possible thanks to the redundant information added to facilitate the access to top concepts and to speed up load­ ing of the alphabetic viewer. this redundant informa­ tion produces an overhead in the load of the model, but without it the drawing time would be much worse, as it would have to generate it on the fly. however, in spite of the improvements, for the larger thesauri considered, the load time starts to be long, given that it includes the load time of all the structure of the thesaurus in memory and the creation of the objects used to manage it quickly when loaded. but, once it is loaded, future accesses are immediate (quicker than 0.5 seconds). these accesses include opening it again, navigating by figure 9. thesaurus concept selector figure 10. thesaurus concept editor article title | author �9thmanager | lacasta, nogueras-iso, lópez-pellicer, muro-medrano, and zarazaga-soria �9 thesaurus relations, changing the visualization language, and searching concepts by their preferred labels. to minimize the load time, thesauri can be loaded in the background when the application is launched, reducing, in that way, the user perception of the load time. another interesting aspect in figure 11 is the peak of the third element. it corresponds with the iso­639 classifica­ tion scheme. it has the special characteristic of not having hierarchy and having many notations. these two character­ istics produce a little increase in the model load time, given that the top concepts list contains all the concepts and the notations are more complex than other relations. but most of the time is used to generate the gui of the tree viewer. the tree viewer gets all the concepts that are top terms, and for each one it asks for their preferred labels in the selected language and sorts them alphabetically to show the first level of the tree. this is fast for a few hundred concepts, but not for the 7,599 in the iso­639. however, this problem could be easily solved if the metadata contained a descrip­ tion of the type of kos to visualize. if the tool knew that the kos does not have broader and narrower relations, it could use the structures used to visualize the alphabetic list, which are optimized to show all of the kos concepts rapidly, instead of trying to load it as a tree. the persistence approach used has the advantage of not requiring external persistence systems, such as a dbms, and providing rapid access after loading, but it has the drawback of loading all thesauri in memory (in time and space). so, for much bigger thesauri, the use of some kind of dbms would be necessary. if this change were necessary, minimum modifications would be needed (one class). however, if not all the concepts are loaded, the alphabetic viewer (shows all the concepts) would have to be updated (for example, showing the concepts by pages) or it would become too slow to work with it. ■ conclusions this article has presented a tool for managing the the­ sauri needed in a digital library, for creating metadata, and for running search processes using skos as the interchange format. this work revises the tools that are available to edit thesauri, highlighting the lack of a formalized way to exchange thesauri and the difficulty of integrating those tools in other environments. this work selects skos from the available interchange formats for thesauri as the most promising format to become a standard for skos repre­ sentation, and highlights the lack of tools that are able to manage it properly. the thmanager tool is offered as the solution to these problems. it is an open source tool that can manage the­ sauri stored in skos, allowing their visualization and editing. thanks to the layered architecture, its components can be easily integrated in other applications that need to use thesauri or other controlled vocabularies. additionally, the components can be used to control the possible values used in a web search service to facilitate traditional or exploratory searches based on a controlled vocabulary. the performance of the tool is proved through a series of experiments on the management of a selected set of thesauri. this work analyzes the features of this selected set of thesauri and compares the efficiency of this tool with respect to other tools that load the thesauri directly from a rdf file. in particular, it is shown that the internal representation used by thmanager helps to decrease the time spent for the graphical loading of thesauri, facilitating navigation of the thesaurus contents as well as other typical operations, such as sorting or change of visual­ ization language. additionally, it is worth noting that the tool can be used as a library of components to simplify the integration of the­ sauri in other applications that require the use of controlled vocabularies. thmanager has been integrated within the open source catmdedit tool table 1. sizes of some thesauri and other types of vocabularies name nc np nr nl lt bt jt ss sb adl ftt 210 210 408 1

2007 (zarazaga­soria et al. 2003), a metadata editor tool for the documentation of geographic information resources (metadata compliant with iso19115 geographic informa­ tion metadata standard). the thesaurusbeans provided in thmanager library have been used to facilitate keyword selection for some metadata elements. the thmanager component library also has contributed to the develop­ ment of catalog search systems guided by controlled vocabularies. for instance, it has been used to build a thematic catalog in the sdiger project (zarazaga­soria 2007). sdiger is a pilot project on the implementa­ tion of the infrastructure for spatial information in europe (inspire) for the development of a spatial data infrastructure to support access to geographic infor­ mation resources concerned with the european water framework directive. thanks to the thmanager compo­ nents, the thematic catalog allows browsing of resources by means of several multilingual thesauri, including gemet, unesco, agrovoc, and eurovoc. future work will enhance the functionalities provided by thmanager. first, the ergonomics will be improved to show connections between different thesauri. currently, these connections can be computed and annotated, but the gui does not allow the user to navigate them. as the base technology already has been developed, only a graphical interface is needed. second, the tool will be enhanced to support data types different from texts (for example, images, documents, or other multimedia sources) for the encoding of concepts’ property values. third, it has been noted that the thesauri concepts can evolve with time. thus, a mechanism for the managing the different ver­ sions of thesauri will be necessary in the future. finally, improvements in usability also are expected. thanks to the component­based design of thmanager widgets (thesaurusbeans), new viewers or editors can be readily created to meet the needs of specific users. ■

jian-zhong, zhou information technology and libraries; mar 2000; 19, 1; proquest pg. 50 tutorial the internet, the world wide web, library web browsers, and library web servers jian-zhong (joe) zhou this article first examines the difference between two very familiar and sometimes synonymous terms, the internet and the web. the article then explains the relationship between the web's protocol http and other high-level internet protocols, such as telnet and ftp, as well as provides a brief history of web development. next, the article analyzes the mechanism in which a web browser (client) "talks" to a web server on the internet. finally, the article studies the market growth for web browsers and web servers between 1993 and 1999. two statistical sources were used in the web market analysis: a survey conducted by the university of delaware libraries for the 122 members of the association of research libraries, and the data for the entire web industry from different web survey agencies. many librarians are now dealing with the internet and the web on a daily basis. while the web is sometimes synonymous with the internet in many people's minds, the two terms are quite distinct, and they refer to different but related concepts in the modem computerized telecommunication system. the internet is nothing more than many small computer networks that have been wired together and allow electronic information to be sent from one network to the next around the world . a piece of data from joe zhou (joezhou@udel.edu) is associate librarian at the university of delaware library, newark. beijing, china may traverse more than a dozen networks while making its way to washington, d.c. we can compare the internet to the great wall of china, which was built in the qin dynasty around the third century b.c. by connecting many existing short defense walls built by previous feudal states . the great wall not only served as a national defense system for ancient china, but also as a fast military communication system. a border alarm was raised by means of smoke signals by day, and beacon fires at night, ignited by burning a mixture of wolf dung , sulfur, and saltpeter. the alarm signal could be relayed over many beacon-fire towers from the western end of the great wall to the eastern end (4,500 miles away) within a day . this was considered light speed two thousand years ago. however, while the great wall transferred the message in a linear mode, the internet is a multidimensional network. the web is a late-comer to the internet, one of the many types of high-level data exchange protocols on the internet. before the web, there was telnet, the traditional commanddriven style of interaction. there was ftp, a file transfer protocol useful for retrieving information from large file archives. there was usenet , a communal bulletin board and news system. there was also e-mail for individual information exchange, and e-mail lists, for one-to-many broadcasts. in addition, there was gopher, a campus-wide information system shared among universities and research institutions, and wais, a powerful search and retrieval system developed by thinking machines, inc. in 1990 tim bemerslee and robert cailliau at cern (www. cern.ch), the european laboratory for particle physics, created a new information system called "world wide web" (www). designed to help the cern scientists with the increasingly confusing task of exchanging information on the 50 information technology and libraries i march 2000 internet, the web system was to act as a unifying force, a system that would seamlessly bind all file-protocols into a single point of access. instead of having to invoke different programs to retrieve information via various protocols, users would be able to use a single program, called a "browser," and allow it to handle all the details of retrieving and displaying information. in december 1993 www received the ima award, and in 1995 bemers-lee and cailliau received the association for computing (acm) software system award for its development. the web is best known for its ability to combine text with graphics and other multimedia on the internet. in addition, the web has some other key features that make it stand out from earlier internet information exchange protocols. since the web is a late-comer to the internet, it has to be compatible backwards with other communications protocols in addition to its native language, hypertext transfer protocol (http). among the foreign languages spoken by web browsers are telnet, ftp, and other high-level communication protocols mentioned earlier. this support for foreign protocols lets people use a single piece of software, the web browser, to access information without worrying about shifting from protocol to protocol and software incompatibility . despite different high-level protocols including http for the web, there is one thing in common for all parts of the internet-tcp/ ip, the lower level of the internet protocol. tcp /ip is respon sible for establishing the connection between two computers on the internet and guarantees that the data can be sent and received intact. the format and content of the data are left for high-level communication protocols to manage, among which the web is the best known one. at the tcp /ip level all computers "are created equal." two computers establish a connection and start to reproduced with permission of the copyright owner. further reproduction prohibited without permission. communicate. in reality, however, most conversations are asymmetric. the end user's machine (the client) usually sends a short request for information, and the remote machine (the server) answers with a longwinded response. the media is the internet. the common language on the internet can be the web or any other high-level protocols . on the web, the client is the web browser; it handles the user's request for a document. the first web browser, ncsa mosaic, developed by the national center for supercomputing applications (ncsa) at the university of illinois at urbanachampaign, was released in midnovember 1993 for unix, windows, and macintosh platforms. version 3.0 of ncsa mosaic is available at www. ncsa. uiuc.ed u/ sdg /software/ mosaic. both source code and binaries are free for academic use. mosaic lost market share to netscape after its key developer left ncsa and joined netscape. even after mosaic introduced an innovative 32-bit version in early 1997, which can perform feats that other major browsers had not even thought of back then, mosaic remained out of the major browsers' market. the two most widely-used browsers today are microsoft's internet explorer (ie) and netscape's navigator (part of the netscape communicator suite). recent web browser surveys conducted by different internet survey companies such as www.zonaresearch.com/ browserstudy, www.psrinc.com/ trends.htm, and www .statmarket. com all indicate that ie is the market leader with more than 60 percent market share, leaving navigator with between 35 percent and 40 percent. in 1995 ie had only 1 percent share versus navigator's more than 90 percent, an unimaginable rise critics have attributed to microsoft's strategy of bundling the browser with its near-monopoly windows operating system. however, a survey conducted in december 1998 by the university of delaware library of 122 members of the association of research libraries (arl) showed that netscape still remained the market leader among big academic libraries. more than 90 percent of arl libraries supported netscape, and about 50 percent also supported ie. most arl libraries supported both browsers, and unlike the browser industry survey mentioned earlier, in which only one product can be picked as the primary browser , the sum of the percentages for the arl survey was greater than 100 percent. the main function of the web browser is to request a document available from a specific server through the internet using the information in the document's url. the server on a remote machine returns the document usually physically stored on one of the server's disks. with the use of common gateway interface (cgi), the documents do not have to be static. rather, they can be synthesized at the point of being requested by cgi scripts running on the server's side of the connection . in some database-driven web servers that make the core of today's e-commerce, the documents provided may never exist as physical files but are generated as needed from database records . the web server can be run on almost any computer, and server software is available for almost all operating systems, such as unix, windows 95/98/nt, macintosh, and os / 2. according to the university of delaware library's 1998 survey of internet web servers among arl member libraries, more than 32 percent of arl libraries chose apache as their web server software, followed by the netscape series at 29.32 percent, ncsa httpd at 11.28 percent, and microsoft internet information server (iis) at 7.52 percent. in july 1999 the author checked the netcraft survey at www .netcraft. com/survey . the top three web server software programs for more than 6.5 million web sites are apache (56.35 percent) , microsoft-hs (22.33 percent), and netscape (5.65 percent). the netcraft survey also provides the historical market share information of major web servers since august 1995. ncsa httpd was the first web server software released, about the same time as the release of mosaic in 1993. however, it slipped from the number-one position with more than 90 percent market share in 1993, and almost 60 percent in 1995, to less than 1 percent in july 1999. it is no longer supported by ncsa, however, httpd remains a popular choice for web servers due to its small size, fast performance, and solid collection of features . the "inertia effect" of the existing sites (if it runs well, why bother to change?) will likely keep ncsa on the major web server software list for some time. ncsa is free, but available only for the unix platform. it is available from http:/ /hoohoo .ncsa.uiuc.edu. however, when the author visited the site in july 1999, the following message appeared on the main page : "the ncsa httpd is no longer under development. it is an unsupported product. we recommend that you check out the apache server, instead of installing our server." most people who use only web browsers may have heard of apache only as an indian nation or a military helicopter, not the most popular web server software with more than 50 percent market share . it was first introduced as a set of fixes or "patches" to the ncsa httpd. apache 1.0 was released in december 1995 as open-source server software by a group of webmasters who named themselves the apache group. open-source means the source code is available and freely distributed, and it is the key to apache's attractiveness and popularity. the apache group members were nsca users tutorial i zhou 51 reproduced with permission of the copyright owner. further reproduction prohibited without permission. who decided to coordinate development work on the server software after nsca stopped. in july 1999 the apache group announced that it was establishing a more formal organization called the apache software foundation (asp). in the future, the asp (www .apache.org) will monitor development of the free software, but it will remain a "not-for-profit" foundation. apache is high-end, enterprise-level server software and can be run on os/2, unix (including linux), and windows platforms, but a mac version is still not available. the netscape series includes netscape-enterprise, netscape-pasttrack, netscape-commerce, and netscape-communication . enterprise is a high-end, enterprise-level server while pasttrack serves as an entrylevel server for small workgroups. netscape supports both the unix and the windows nt platforms. the other major commercial web server, microsoft internet information server (iis), as of 1999, is only available for the windows platform. however, one advantage of iis over netscape is that it can be downloaded for free as part of the windows option pack. in addition, iis can handle ms office documents very well. while both the microsoft and netscape brand names are well recognized by millions of end users. a name alone does not necessarily equate to large market share, nor does a deep pocket. apache remains the top web server despite intense competition. one of the keys to apache's success, in addition to its outstanding performance, lies in its open-source code movement and active user support on a wide basis. the web server of choice for the macintosh platforms is webstar. however, due to the limitations of the operating system networking software, the performance of macintosh-based servers has not been great. webstar can be downloaded as a free evaluation release from www.stamine.com/webstar. the web server market is dynam52 information technology and libraries i march 2000 ic and competition intense. there are more than sixty web server products on the top list ( of web servers with more than one thousand web sites) as of july 1999, and newcomers are being added frequently.

for public libraries leading the way online ticketed-passes: a mid-tech leap in what libraries are for jeffrey davis information technology and libraries | june 2019 8 jeffrey davis (jtrappdavis@gmail.com) is branch manager at san diego public library, san diego, california. last year a library program received coverage from the new york times, the wall street journal, the magazines mental floss and travel+leisure, many local newspapers and tv outlets, online and trade publications like curbed, thrillist, and artforum, and more. that program is new york’s culture pass, a joint program of the new york, brooklyn, and queens public libraries. culture pass is an online ticketed-pass program providing access to area museums, gardens, performances, and other attractions. as the new york daily news wrote in their lede: “it’s hard to believe nobody thought of it sooner: a new york city library card can now get you into 33 museums free.” libraries had thought of it sooner, of course. museum pass programs in libraries began at least as early as 1995 at boston public library and the online ticketed model in 2011 at contra costa (ca) county library. the library profession has paid this “mid-tech” program too little attention, i think, but that may be starting to change. what are online ticketed-passes? the original museum pass programs in libraries circulate a physical pass that provides access to an attraction or group of attractions. sometimes libraries are able to negotiate free or discounted passes but many times the passes are purchased outright. the circulating model is still the most common for library pass programs, but it suffers from many limitations. passes by necessity are checked out for longer than they’re used. they sit waiting for pick up on hold shelves and in transit to their next location. long queues make it hard for patrons to predict when their requests will be filled, and therefore difficult to plan on using. for the participating attractions, physical passes are typically good anytime and so compete with memberships and paid admission. there are few ways to shape who borrows the passes in order to meet institutional goals. and there are few ways to limit repeat use by library patrons to both increase exposure and nudge users toward membership. as a result, most circulating pass programs only connect patrons to a small number of venues. despite these limitations, circulating passes have been incredibly popular: at writing there are 967 requests for san diego public library’s 73 passes to the new children’s museum. we sometimes see that sort of interest in a new bestseller, but this is a pass that sdpl has offered continuously since 2009. in 2011, contra costa county library launched the first “ticketed-pass” program, discover & go. discover & go replaced circulating physical passes with an online system with which patrons, remotely or in the library with staff assistance, retrieve day-passes — tickets — by available date or venue. this relatively simple and common-sense change makes an enormous difference. in addition to convenience and predictability for patrons, availability is markedly increased because venues are much more comfortable providing passes when they can manage their use: patrons can be restricted to a limited number of tickets per venue per year and venues can match the information technology and libraries | june 2019 9 number of tickets available to days that they are less busy. the latter preserves the value of their memberships while making use of their own “surplus capacity” to bring in new visitors and potential new members. funding and internal expectations at many venues carry obligations to reach underserved communities and the programs allow partner attractions to shape public access and receive reporting by patron zip code and other factors. the epass software behind discover & go is regional by design and supports sharing of tickets across multiple library systems in ways that are impractical to do with physical passes. as new library systems join the program, they bring new partner attractions into the shared collection with them. the oakland zoo, for example, needs only to negotiate with their contact at oakland public library to coordinate access for members of oakland, san francisco, and san jose public libraries. because of the increased attractiveness of participation, it’s been easier for libraries to bring venues into the program. in 2011, discover & go hoped for a launch collection of five museums but ultimately opened with forty. the success of ticketed-pass programs in turn attracts more partners. today, discover & go is available through 49 library systems in california and nevada with passes to 137 participating attractions. similarly, new york’s culture pass launched with 33 participating venues and has grown in less than a year to offer a collection of 49. while big city programs attract the most attention, pass programs are offered by county systems like alamace county (nc), consortiums like libraries in clackamas county (or), small cities like lawrence (ma), small towns like atkinson (nh), and statewide like the michigan activity pass which is available through over 600 library sites with tickets to 179 destinations plus state parks, camping, and historical sites. for each library, the participating destinations form a unique collection: a shelf of local riches, idiosyncratic and rooted in place. through various libraries one can find tickets for the basketball hall of fame, stone barns center for food and agriculture, dinosaur ridge, eric carle museum of picture book art, bushnell park carousel, california shakespeare theater, children’s museums, zoos, aquariums, botanical gardens, tours, classes, performances, and on to the met, moma, crocker, de young, and many, many, many more. for kids, “enrichments” like these are increasingly understood as essential parts of learning and exploration. for adults, access to our cultural treasures, including partners like san francisco’s museum of the african diaspora or chicago’s national museum of puerto rican arts & culture — besides being its own reward — enhances local connection and understanding. we’re also starting to see the ticketing platform itself become an asset to smaller organizations — craft studios, school performances, farm visits, nature centers, and more — that want to increase public access without having to take on a new ability. importantly, ticketed-pass programs are built on the core skills of librarians: information management, collection development, community outreach, user-centered design, customer service, and technological savvy. the technology discover & go was initially funded by a $45,000 grant from the bay area library and information system (balis) cooperative. contra costa contracted with library software company quipu group to develop the epass software that runs the program and that is also used by ny’s culture pass, public libraries leading the way: online ticketed passes | davis 10 https://doi.org/10.6017/ital.v38i2.11141 multnomah county (or) library’s my discovery pass, and a consortium of oregon libraries as cultural pass. ticketed-pass software is also offered by the libraryinsight and plymouth rocket companies and used by denver public library, seattle public library, the michigan activity pass, and others. the software consists of a web application with a responsive patron interface and connects over sip2 or vendor api to patron status information from the library ils. administrative tools set finegrained ticket availability, blackout dates, and policies including restrictions by patron age, library system, zip code, municipality, number of uses allowed globally and per venue, and more. recent improvements to epass include geolocation to identify nearby attractions and improved search filters. still in development are transfer of tickets between accounts, re-pooling of unclaimed tickets, and better handling of replaced library cards. the strength that comes from multi-system ticketed-pass programs also carries with it challenges on the patron account side. ilses each implement protocols and apis for working with patron account information differently and library systems maintain divergent policies around patron status. there’s a role for lita and for library consortia and state libraries to push for more attention to and consistency on patron account policies and standards. the emphasis in library automation is similarly shifting. our ilses originated to manage the circulation of physical items, a catalog-centric view. today, as robert anderson of quipu group suggested to me, a diverse range of online and offline services and non-catalog offerings orbit our users, calling for a new frame of reference: “it’s a patron-centric world now.” the vision library membership is the lynchpin of ticketed-pass and complementary programs in the technical sense, as above, and conceptually: library membership as one’s ticket to the world around. though i’m not aware of academic libraries offering ticketed-passes, they have been providing local access through membership. at many campuses, the library is the source for one’s library card which is also one’s campus id, onand off-campus cash card, transit pass, electronic key, print management, and more. that’s kind of remarkable and deserving of more attention. traditionally, librarians have responded to patron needs by providing information, resources, and services ourselves. new models and technologies are making it easier to complement this with the facilitation approach, of which online ticketed-passes are the quintessential example. we further increase access by reducing barriers of complexity, language, know-how, and social capital, for example, by maintaining community calendars of local goings-on or helping communities take advantage of nearby nature. online ticketed-pass programs will grow and take their place in the public’s expectations of libraries and librarians: that libraries are the place that help us (better, more equitably) access the resources and riches around us. powering this are important new tools for library technologists to interrogate and advance with the same attention we give to both more established and more speculative applications. 52 information technology and libraries | june 2006 author name and second author author id box for 2 column layout this paper discusses google scholar as an extension of kilgour’s goal to improve the availability of information. kilgour was instrumental in the early development of the online library catalog, and he proposed passage retrieval to aid in information seeking. google scholar is a direct descendent of these technologies foreseen by kilgour. google scholar holds promise as a means for libraries to expand their reach to new user communities, and to enable libraries to provide quality resources to users during their online search process. editor’s note: this article was submitted in honor of the fortieth anniversaries of lita and ital. f red kilgour would probably approve of google scholar. kilgour wrote that the paramount goal of his professional career is “improving the availability of information.”1 he wrote about his goal of achieving this increase through shared electronic cataloging, and even argued that shared electronic cataloging will move libraries toward the goal of 100 percent availability of information.2 throughout much of kilgour’s life, 100 percent availability of information meant that all of a library’s books would be on the shelves when a user needed them. in proposing shared electronic cataloging—in other words, online union catalogs—kilgour was proposing that users could identify libraries’ holdings without having to travel to the library to use the card catalog. this would make the holdings of remote libraries as visible to users as the holdings of their local library. kilgour went further than this, however, and also proposed that the full text of books could be made available to users electronically.3 this would move libraries toward the goal of 100 percent availability of information even more than online union catalogs. an electronic resource, unlike physical items, is never checked out; it may, in theory, be simultaneously used by an unlimited number of users. where there are restrictions on the number of users of an electronic resource—as with subscription services such as netlibrary, for example—this is not a necessary limitation of the technology, but rather a limitation imposed by licensing and legal arrangements. kilgour understood that his goal of 100 percent availability of information would only be reached by leveraging increasingly powerful technologies. the existence of effective search tools and the usability of those tools would be crucial so that the user would be able to locate available information without assistance.4 to achieve this goal, therefore, kilgour proposed and was instrumental in the early development of much library automation: he was behind the first uses of punched cards for keeping circulation records, he was behind the development of the first online union catalog, and he called for passage retrieval for information seeking at a time when such systems were first being developed.5 this development and application of technology was all directed toward the goal of improving the availability of information. kilgour stated that the goal of these proposed information-retrieval and other systems was “to supply the user with the information he requires, and only that information.”6 shared catalogs and electronically available text have the effect of removing both spatial and temporal barriers between the user and the material being used. when the user can access materials “from a personal microcomputer that may be located in a home, dormitory, office, or school,” the user no longer has to physically go to the library.7 this is a spatial barrier when the library is located at some distance from the user, or if the user is physically constrained in some way. even if the user is perfectly able-bodied, however, and located close to a library, electronic access still eliminates a temporal barrier: accessing materials online is frequently faster and more convenient than physically going to the library. electronic access enables 100 percent availability of information in two ways: by ensuring that the material is available when the user wants it, and by lowering or removing any actual or perceived barriers to the user accessing the material. ■ library automation weise writes that “for at least the last twenty to thirty years, we [librarians] have done our best to provide them [users] with services so they won’t have to come to the library.”8 the services that weise is referring to are the ability for users to search for and gain access to the full text of materials online. libraries of all types have widely adopted these services: for example, at the author’s own institution, the university of north carolina at chapel hill, the libraries have subscriptions to approximately seven hundred databases and provide access to more than 32,000 unique periodical titles; many of these subscriptions provide access to the full text of materials.9 additionally, the state library of north carolina provides a set of more than one hundred database subscriptions to all academic and public libraries around the jeffrey pomerantz jeffrey pomerantz (pomerantz@unc.edu) is assistant pro fessor in the school of information and library science, university of north carolina at chapel hill. google scholar and 100 percent availability of information google scholar and 100 percent availability of information | pomerantz 53 state; any north carolina resident with a library card may access these databases.10 several other states have similar programs. by providing users with remote access to materials, libraries have created an environment in which it is possible for users to be remote from the library. or rather, as lipow points out, it is the library that is remote from the user, yet the user is able to seek and find information.11 this adoption of technology by libraries has had the effect of enabling and empowering users to seek information for themselves, without either physically going to a library or seeking a librarian’s assistance. the increasing sophistication of freely available tools for information seeking on the web has accelerated this trend. in many cases, users may seek information for themselves online without making any use of a library’s human-intermediated or other traditional services. (certainly, providing access to electronic collections may be considered to be a service of the library, but this is a service that may not require the user either to be physically in the library or to communicate with a librarian.) even technically unsophisticated users may use a search engine and locate information that is “good enough” to fulfill their information needs, even if it is not the ideal or most complete information for those purposes.12 thus, for better or worse, the physical library is no longer the primary focus for many information seekers. part of this movement by users toward self-sufficiency in information seeking is due to the success of the web search engine, and to the success of google in particular. recent reports from the pew internet and american life project shed a great deal of light on users’ use of these tools. rainie and horrigan found that “on a typical day at the end of 2004, some 70 million american adults logged onto the internet.”13 fallows found that “on any given day, 56% of those online use search engines.”14 fallows, rainie, and mudd found that of their respondents, “47% say that google is their top choice of search engine.”15 from these figures, it can be roughly estimated that more than 39 million people use search engines, and more than 18 million use google on any given day—and that is only within the united states. this trend seems quite dark for libraries, but it actually has its bright side. it is important to make a distinction here between use of a search engine and use of a reference service or other library service. there is some evidence that users’ questions to library reference services are becoming more complex.16 why this is occurring is less clear, but it may be hypothesized that users are locating information that is good enough to answer their own simple questions using search engines or other internet-based tools. the definition of “good enough” may differ considerably between a user and a librarian. nevertheless, one function of the library is education, and as with all education, the ultimate goal is to make the student self-sufficient in self-teaching. in the context of the library, this means that one goal is to make the user self-sufficient in finding, evaluating, and using information resources. if users are answering their own simple questions, and asking the more difficult questions, then it may be hypothesized that the widespread use of search engines has had a role in raising the level of debate, so to speak, in libraries. rather than providing instruction to users on simply using search engines, librarians may now assume that some percentage of library users possess this skill, and may focus on teaching higher-level information-literacy skills to users (www.ala.org/ala/acrl/ acrlstandards/informationliteracycompetency.htm). simple questions that users may answer for themselves using a search engine, and complex questions requiring a librarian’s assistance to answer are not opposites, of course, but rather two ends of a spectrum of the complexity of questions. while the advance of online search tools may enable users to seek and find information for themselves at one end of this spectrum, it seems unlikely that such tools will enable users to do the same across the entire spectrum any time soon; perhaps ever. the author believes that there will continue to be a role for librarians in assisting users to find, evaluate, and use information. it is also important to make another distinction here, between the discovery of resources, and access to those resources. libraries have always provided mechanisms for users to both discover and access resources. neither the card catalog nor the online catalog contains the full text of the materials cataloged; rather, these tools are means to enable the user to discover the existence of resources. the user may then access these resources by visiting the library. search engines, similar to the card and online catalogs, are tools primarily for discovery of resources: search-engine databases may contain cached copies of web pages, but the original (and most up-todate) version of the web page resides elsewhere on the web. thus, a search engine enables the user to discover the existence of web pages, but the user must then access those web pages elsewhere. the author believes that there will continue to be a role for libraries in providing access to resources—regardless of where the user has discovered those resources. in order to ensure that libraries and librarians remain a critical part of the user’s information-seeking process, however, libraries must reappropriate technologies for online information seeking. search engines may exist separate from libraries, and users may use them without making use of any library service. however, libraries are already the venue through which users access much online content—newspapers, journals, and other periodicals; reference sources; genealogical materials—even if many users do not physically come to the library or consult a librarian when using them. it is possible for 54 information technology and libraries | june 2006 libraries to add value to search technologies by providing a layer of service available to those using it. ■ google scholar one such technology for online information seeking to which libraries are already adding value, and that could add value to libraries in turn, is google scholar (scholar. google.com). google scholar is a specialty search tool, obviously provided by google, which enables the user to search for scholarly literature online. this literature may be on the free web (as open-access publications become more common and as scholars increasingly post preprint or post-print copies of their work on their personal web sites), or it may be in subscription databases.17 users may access literature in subscription databases in one of two ways: (1) if the user is affiliated with an institution that subscribes to the database, the user may access it via whatever authentication method is in place at the institution (e.g., ip authentication, a proxy server), or (2) if the user is not affiliated with such an institution, the user may pay for access to individual resources on a pay-perview basis. there is not sufficient space here to explore the details of google scholar’s operation, and anyway that is not the point of this paper; for excellent discussions of the operation of google scholar, see gardner and eng, and jacsó.18 pace draws a distinction between federated searching and metasearching: federated search tools compile and index all resources proactively, prior to any user’s actual search, in a just-in-case approach to users’ searching.19 metasearch tools, on the other hand, search all resources on the fly at the time of a user’s search, in a just-in-time approach to users’ searching. google scholar is a federated search tool—as, indeed, are all of google’s current services—in that the database that the user searches is compiled prior to the user’s actual search. in this, google scholar is a direct descendent of kilgour’s work to develop shared online library catalogs. a shared library catalog is a union catalog: it is a database of libraries’ physical holdings, compiled prior to any actual user’s search. google scholar is also a union catalog, though a catalog of publishers’ electronic offerings provided by libraries, rather than of libraries’ physical holdings. it should be noted, however, that while this difference is an important one for libraries and publishers, it might not be understood or even relevant for many users. many of the resources indexed in google scholar are also available in full text. this fact allows google scholar to also move in the direction of kilgour’s goal of making passage retrieval possible for scholarly work. by using google’s core technology—the search engine and the inverted index that is created when pages are indexed by a search engine—google scholar enables full-text searching of scholarly work. as mentioned above, when users search google scholar, they retrieve a set of links to the scholarly literature retrieved by the search. google scholar also makes use of google’s linkanalysis algorithms to analyze the network of citations between publications—instead of the network of hyperlinks between web pages, as google’s search engine more typically analyzes. a cited by link is included with each retrieved link in google scholar, stating how many other publications cite the publication listed. clicking on this cited by link performs a preformulated search for those publications. this citation-analysis functionality resembles the functionality of one of the most common and widely used scholarly databases in the scholarly community: the isi web of science (wos) database (scientific .thomson.com/products/wos). wos enables users to track citations between publications. this functionality has wide use in scholarly research, but until google scholar, it has been largely unknown outside of the scholarly community. with the advent of google scholar, however, this functionality may be employed by any user for any research. further, there is a plugin for the firefox browser (www.mozilla.com/firefox) that displays an icon for every record on the page of retrieved results that links to the appropriate record in the library’s opac (google scholar does not, however, currently provide this functionality natively20). this provides a link from google scholar to the materials that the library holds in its collection. when the item is a book, for example, this link to the opac enables users to find the call number of the book in their local library. when the item is a journal, it enables them to find both the call number and any database subscriptions that index that journal title. periodicals are often indexed in multiple databases, so libraries with multiple-database subscriptions often have multiple means of accessing electronic versions of journal titles. a library user may access a periodical via any or all of these individual subscriptions without using google scholar— but to do so, the user must know which database to use, which means knowing either the topical scope of a database or knowing which specific journals are indexed in a database. as a more centralized means of accessing this material, many users may prefer a link in google scholar to the library’s opac. google scholar thus fulfills, in large part, kilgour’s vision of shared electronic cataloging. in turn, shared cataloging goes a long way toward achieving kilgour’s vision of 100 percent availability of information by allowing a user to discover the existence of information resources. however, discovery of resources is only half of the equation: the other half is access to those resources. and it is here where libraries may position themselves as a critical part of the information-seeking process. search engines google scholar and 100 percent availability of information | pomerantz 55 may enable users to discover information resources on their own, without making use of a library’s services, but it is the library that provides the “last mile” of service, enabling users to gain access to many of those resources. ■ conclusion google scholar is the topic of a great deal of debate, both in the library arena and elsewhere.21 unlike union catalogs and many other online resources used in libraries, it is unknown what materials are included in google scholar, since as of this writing google has not released information about which publishers, titles, and dates are indexed.22 google is known to engage in self-censorship—or self-filtering, depending on what coverage one reads—and so potentially conflicts with the american library association’s freedom to read statement (www .ala.org/ala/oif/statementspols/ftrstatement/freedom readstatement.htm).23 google is a commercial entity and, as such, a primary motivation of google must be profit, and only secondarily, meeting the information needs of library users. for all of these and other reasons, there is considerable debate among librarians about whether it is appropriate for libraries to provide access to google scholar. despite this debate, however, users are using google scholar. google scholar is simply the latest tool to enable users to seek information for themselves; it isn’t the first and it won’t be the last. google scholar holds a great deal of promise for libraries due to the combination of google’s popularity and ease of use, and the resources held by or subscribed to by libraries to which google scholar points. as kesselman and watstein suggest, “libraries and librarians need to have a voice” in how tools such as google scholar are used, given that “we are the ones most passionate about meeting the information needs of our users.” given that library users are using google scholar, it is to libraries’ benefit to see that it is used well. google scholar is the latest tool in a long history of information-seeking technologies that increasingly realize kilgour’s goal of achieving 100 percent availability of information. google scholar does not provide access to 100 percent of information resources in existence; but rather enables discovery of information resources, and allows for the possibility that these resources will be discoverable by the user 100 percent of the time. google scholar may be on the vanguard of a new way of integrating library services into users’ everyday information-seeking habits. as taylor tells us, people have their own individual sources to which they go to find information, and libraries—for many people—are not at the top of their lists.25 google, however, is at the top of the list for a great many people.26 properly harnessed by libraries, therefore, google scholar has the potential to bring users to library resources when they are seeking information. google scholar may not bring users physically to the library. instead, what google scholar can do is bring users into contact with resources provided by the library. this is an important distinction, because it reinforces a change that libraries have been undergoing since the advent of the online database: that of providing access to materials that the library may not own. ownership of materials potentially allows for a greater measure of control over the materials and their use. ownership in the context of libraries has traditionally meant ownership of physical materials, and physical materials by nature restrict use, since the user must be physically collocated with the materials, and use of materials by one user precludes use of those materials by other users for the duration of the use. providing access to materials, on the other hand, means that the library may have less control over materials and their use, but this potentially allows for wider use of these materials. by enabling users to come into contact with library resources in the course of their ordinary web searches, google scholar has the potential to ensure that libraries remain a critical part of the user’s information-seeking process. it benefits google when a library participates with google scholar, but it also benefits the library and the library’s users: the library is able to provide users with a familiar and easy-to-use path to materials. this is (for lack of a better term) a “spoonful of sugar” approach to seeking and finding information resources: by using an interface that is familiar to users, libraries may provide quality information sources in response to users’ information seeking. green wrote that “a librarian should be as unwilling to allow an inquirer to leave the library with his question unanswered as a shop-keeper is to have a customer go out of his store without making a purchase.”27 a modern version of this might be that a librarian should be as unwilling to allow an inquirer to abandon a search with his question unanswered. google scholar and online tools like it have the potential to draw users away from libraries; however, these tools also have the potential to usher in a new era of service for libraries: an expansion of the reach of libraries to new users and user communities; a closer integration with users’ searches for information; and the provision of quality resources to all users, in response to all information needs. google scholar and online tools like it have the potential to enable libraries to realize kilgour ’s goals of improving the availability of information, and to provide 100 percent availability of information. these are goals on which all libraries can agree. 56 information technology and libraries | june 2006 ■ acknowledgements many thanks to lisa norberg, instruction

authentication. while care will be taken to keep the authentication exchange secure, the network will otherwise transmit data without encryption. w ireless networks are an essential tool for provid­ ing service for colleges and libraries. this paper will explain the setup of a wireless network using open­source software and inexpensive commodity hardware. open­source software was employed exclu­ sively. this allowed for flexibility in design and reduction in expense while also providing a platform for students to learn more about the internal workings of the system by examining particular sections of code in which they have interest. standard commodity hardware was used as a means of saving cost. this should allow others to repeat this design with a minimum of funding. the purpose of a network, like any resource, is to provide a service for those who own it; in this case, the patrons of a library, or students, faculty, and staff at a col­ lege. to ensure that this network serves its owners, users will be required to authenticate before gaining access. once authenticated, the central captive portal can pro­ vide different levels of service for specific user groups, including guest access, if desired. for this system, ease of access for users was the primary concern; other than using the secure socket layer for authentication, the remainder of the traffic was unencrypted. other than the base nodes, the remaining access points were connected to each other using a wireless connection in order to avoid physically connecting all access points across campus and to further reduce the expense for the deployment of the network. this was accomplished using the wds (wireless distributed system) feature on the wireless routers. all access points connect to a centralized set of servers that provide: dhcp, web­caching proxy, dns caching, radius, web server, a captive portal, and logging of network traffic. n hardware requirements for the network were relatively modest, using inexpensive wireless routers along with several linux servers built upon older pentium 3 desktop systems. linksys wrt54gs routers were chosen as the access points as they are inexpensive, readily available, and possess the ability to run custom open­source firmware. other access points could be used; however, the configuration sugges­ tions are specific to the wrt54gs and may not apply to other hardware. the routing functions of the wrt54gs were not used in this implementation. the servers need not be anything special; older hardware will work just fine. for this implementation, decommissioned 900 mhz units with 512mb of ram and 40gb hard drives were used. n wireless router software in order to provide the functionality required, the units had their firmware flashed with an open­source, linux­ based operating system available from openwrt for the linksys routers (http://www.openwrt.org). support is also available for other wireless devices. “the firmware from openwrt provides a fully writable file system with pack­ age management. this allows developers the freedom to customize the devices by choosing only the packages and software that are necessary for their applications.”1 as the routers have limited storage, being able to hand select only the necessary components is a definite advantage. n server software for the operating system on the servers, fedora core was chosen.2 fedora provides the yellow dog updater, modified (yum), which eases the updating of all pack­ ages installed on the system, including kernel updates.3 this aids security by providing a platform for easily and frequently updating the system. fedora core is an open­ source distribution that is available for free. fedora core also comes with many other open­source packages that were used in this design, such as the apache web server. while the designers had more familiarity with fedora, other distributions are also available that provide simi­ lar benefits (suse, ubuntu, openbsd, debian, etc.). the server was run in command line mode with no graphical user interface in order to reduce the load on the server and save space on the hard drive. n captive portal in order to require authentication before gaining access to the network, a captive portal was used. some of the open source wifi hotspot implementation | sondag and feher 35 open source wifi hotspot implementation tyler sondag and jim feher jim feher (jdfeher@mckendree.edu) is an associate professor of computer science at mckendree college in lebanon, illinois. tyler sondag (tnsondag@mckendree.edu), is a senior in computer science at mckendree college. 36 information technology and libraries | june 200736 information technology and libraries | june 2007 desired features in the choice of the captive portal were: encrypted authentication, traffic logging, and the ability to provide different levels of service for different user groups. logging traffic allows the system administrators to identify accounts that have been misusing the network. those who inadvertently misuse the system or perhaps have had their accounts compromised can have their access temporarily disabled until they can be contacted with instructions concerning acceptable use of the net­ work. as the network must be shared by all, those who habitually abuse the resource can have their accounts per­ manently disabled. the captive portal should also redi­ rect web traffic to a login page that is served on the secure socket layer until the user logs in. chillispot was chosen as it possesses all of the features mentioned above.4 n server layout as can be seen in appendix a, three servers were used for this implementation. the first server was used as the main router to the internet. the second server ran a squid web caching server.5 it also ran a dns cach­ ing server and the freeradius server.6 the third was used for the captive portal. three servers were used for various reasons. first, this distributed the load. second, portions of the network that were not behind the cap­ tive portal could more easily use the services on the second server running squid, dns, and freeradius. it should be noted that three independent servers are not required; many of the services could be consolidated on two or even one single server to reduce the hardware requirements. the implementation depends upon the specific needs for the network. n server installation installing the operating system (fedora core) on each server is a relatively straightforward procedure. each machine was partitioned with 1024 mbs of swap space with the rest of the drive being an ext3 partition with the mount point “/”. only the minimal set of packages required were installed at this time. the first server, server #1 (router), was given three network interfaces, one for the internet connection, one to connect to a switch that then connects to server #2 (web/dns caching and radius) as well as other machines that do not connect through the captive portal, and one connecting to server #3 (captive portal machine). the second server, server #2, only needs one interface, but the third, server #3, requires two interfaces, one for the master wireless access point, and one to connect to the switch connecting this machine to the rest of the network (appendix a). ssh login for root was also disabled at this time for added security. n server #1 configuration for server #1, very little setup was required. since this server works mainly as a router, the only major items that went into its configuration were the iptables rules, which are shown and described in appendix b.7 rules were set up to: n set up network address translation; n allow traffic to flow within the network; n log the traffic from the wireless portion of the net­ work; n allow for the transparent setup of the web proxy server; and n set up port knocking before allowing users to log into the router via ssh.8 a reference to this script was placed in the /etc/rc.d/ rc.local file so that it would run when the server boots. last was the setup of the three network interfaces in the machine. this can be done during system installation or afterwards on the fedora core based server by editing the configuration files in the /etc/sysconfig/networking­ scripts/ directory. one of the configuration files used in this implementation can be seen in appendix c. of course the configuration will change as the topology of the net­ work changes. n server #2 configuration the second server required significantly more setup to configure all of the necessary services that it runs. the first service added for this implementation was the web­ caching proxy server, squid. squid’s default configura­ tion file (/etc/squid.conf) is quite large; fortunately it requires little modification to get a simple server up and running.9 the changes made for this implementation can be seen in appendix d. the most important lines in this configuration are the last few, which enable it to act as a transparent proxy server, making it invisible to the users and requiring no setup of their browsers. as there was no need for an authoritative dns server, just dns caching for the network, dnsmasq, which is easy to configure and can handle both dhcp services as well as dns caching, was chosen.10 in this instance, the captive portal was used to provide dhcp services for the wireless clients; however dnsmasq was used for dynamic clients on the remaining portion of the network. dnsmasq public libraries and internet access | jaeger, bertot, mcclure, and rodriguez 37open source wifi hotspot implementation | sondag and feher 37 is relatively easy to configure, requiring only one change in its default configuration file, which points to the file in which the dns server addresses are stored, in this case /etc/dnsmasq_resolv.conf. next is the configuration of freeradius server. there are two files that need to be modified for the radius server; both are in the /etc/raddb/ directory. the first is clients.conf (appendix e). in this file at least two clients must be listed, one for localhost (this machine) and one for the captive portal machine. for each machine, a pass­ word must be specified as well as the hostname for that machine. this establishes the shared key that is used to encrypt communication between the captive portal and the radius server. the second is the users file (appendix f). in this file, each user for the captive portal system must be listed with his/her password. this implementa­ tion also included a class, a session timeout (dhcp lease time), idle timeout, accounting interim interval, and the maximum upload and download speeds. if guest access is required, one or several guest accounts should be added to this file along with entries for the registered users. an entry was added for each access point so that they can obtain an ip address from the dhcp server. finally for this machine, the interface configuration file was changed according to the network specifications. for this machine the configuration is simple since it only has one interface, and the only requirement for its address is that it be on the same network as the interface on the main router server to which it is connected. n server #3 configuration the third server required the installation of the captive portal software, in this case chillispot. in order to install chillispot, if fedora was used for the base system, it may be possible to install it as a prepackaged binary in the form an rpm package manager (rpm) file. otherwise, if you find that you need to compile chillispot from source code, you may need to deviate from a minimal installa­ tion of the operating system and base components and also include the gnu compiler collection (gcc). when installing from source code, first download the code from the chillispot web site. once the code is down­ loaded, unzipped and untarred, installing the chillispot daemon is done by entering the directory containing the source files and entering the standard commands: ./configure make make install when chillispot is on the system, either by compiling from source or through an rpm file, two more files must be configured and copied to the proper directory, the main configuration file and the login file. the configuration file, chilli.conf, is located in the directory that contains the source files. move this file to the /etc/ directory and make the necessary changes. in this implementation, the file required several changes (appendix g). one of the more significant alterations was to change the default network range of 192.168.182.0/24, which would be limited to less than 256 addresses. the address range was for the dhcp server was also expanded to allow for more users. the lower portion of the network range was left to make room for addresses that could be assigned to the wireless access points. an entry was added to allow the access points to obtain a static ip address in that lower range. after this, settings must be changed for the dns addresses given out to clients, and the address of the radius server. there is also a setting in the chillispot configuration file that allows users to access a certain list of domains without logging in. for this implementation, the decision was to allow the users access to the campus network, as well as to the dns server. next, the “radi­ ussecret” must be set. this is the same password that was entered into the clients.conf file on the radius server for this machine. it is also necessary to set the address of the page to which users will be directed. two lines must also be added to allow authentication using the physical or media access control (mac) address for the access points. all of the access points shared a common password. chillispot passes the physical address of the access point to the radius server along with this password. a separate entry must exist in the radius configuration file for each ip/physical address combination. for this setup, the redirect page was placed on this server, therefore apache (using yum) was also installed, and this server’s address was added as the web address for the redirect page (also note that the https module may be required for apache if it does not automatically install). rather than write a new page at this time, the sample page (hotspotlogin.cgi) from the chillispot source folder was copied and modified slightly (appendix h). in addi­ tion, a secure socket layer (ssl) certificate was installed on this server. this is not necessary, but it helps to avoid the warnings that pop up when a client attempts to access the login page with a browser. a few iptables rules need to be added. the first com­ mand needs to be executed in order to utilize network address translation (nat) and have the server forward packets to the outside network. /sbin/iptables ­t nat ­a postrouting ­o eth0 \ ­j masquerade the next is used to drop all outbound traffic originating from the access points. this prevents anyone spoofing the physical address of the access point from accessing 3� information technology and libraries | june 20073� information technology and libraries | june 2007 the internet, while still allowing the access points and the chillispot server to communicate for configuration and monitoring. /sbin/iptables ­a forward ­s 192.168.182.0/24 \ ­j drop these commands need to be executed when the chillispot machine boots, so they were placed into the /etc/rc.d/rc.local file. it may also be necessary to ensure that the machine can forward network traffic. this can be accomplished with the following command, which is also found as the first executable command from the script in appendix b: echo “1” > /proc/sys/net/ipv4/ip_forward finally, the configuration files for the interfaces were set up. n openwrt installation and configuration several ways exist to replace the default linksys firmware with the openwrt firmware.11 the tftp protocol can be used with both windows and linux, and one such method can be found in appendix i.12 in addition, other methods for using the standard web interface can be found on the openwrt web site.13 there are several versions of the openwrt firmware available; the newest version that uses the squashfs filesystem was chosen because it utilizes com­ pression that frees more space on the access point. openwrt comes with a default web interface that can be used for configuration, however, ssh was enabled and a script using the nvram command was used to configure each access point (see appendix j). before ssh can be used, you must telnet into the router and change the default password (which for linksys routers is ‘admin’). note: even if you decide to use the web interface, you should still change the default password. as several services that were installed with the default configuration were not used in the implementa­ tion, they were disabled once the firmware was flashed by removing the modules that boot at startup: the web interface, dnsmasq, and the firewall. this is done by deleting their entries in the /etc/init.d directory. changes were needed to set the mode of the access point, to turn on and configure the clients needing to use wds, to set the network information for the access point and then to save these settings. all of the wireless access points that communicate with each other via a wireless connec­ tion must have their physical addresses entered using a nvram command. for example, the command used for the main access point for the library would be: nvram set w10_wds=”mac_4_lib1 mac_4_lib2” all of this is detailed in appendix j. a final set of com­ mands, which were needed for the wrt54gs, are included to allow the access point to obtain its ip address from the dhcp server. these commands may not be necessary depending upon the type of access point used. since extra wireless access points are available, if an access point fails or is having problems for some reason, it is simply a matter of running a script similar to the one found in the appendix on one of the extra routers and swapping it out. n security unfortunately this system is not very secure. only the login credentials are encrypted via ssl. general data packets are in no way encrypted, so any information being transmitted is available to anyone sniffing the channel. wep and wpa could be used for encryption, but they have known vulnerabilities. other methods exist for securing the network such as wpa with radius or the use of a virtual private network, however the client setup for such systems may not be considered trivial for the typical user. therefore it was decided that it was better to inform the users that the data was not being encrypted and let them act accordingly, rather than use encryption with known flaws or invest the time required to train the general population on how to configure their mobile units to use a more secure form of encryption. as the main goal of this particular network was connectivity and not security, it was felt that this was a fair trade­ off. as new standards for wireless communication are developed and commodity hardware that supports them becomes available, this may change so that encrypted channels can be employed more easily. n conclusion this implementation is in no way completed. it is a work in progress, with many goals still in mind. also, as new features are desired, parts of the system will change to accommodate these requirements. current plans for the future are first to develop scripts to check the status of the access points and display this information to a web page. these scripts will also notify network administrators when access points go offline. this will help the adminis­ trators in making sure the system is up at all times. after this, scripts will be developed to parse the log files to find abusive activity (spamming, viruses, etc). however, the current project as described is complete and has already functioned successfully for nearly a year providing con­ nectivity for the library and portions of the mckendree college campus.

linksys router the firmware can be flashed using the built­in web inter­ face or via tftp. while help is available online3 for this, the procedure outlined here may also be helpful. on newer versions of the linksys routers, an older version of the linksys firmware must be installed first that supports a bug in the ping function on the router. once the older version is installed, you can exploit a bug in the ping com­ mand on the router to enable “boot wait,” which enables the router to accept a connection to flash its firmware as it is booting. detailed instructions for this installation are as fol­ lows: n first, download an old version of a linksys firmware that supports the ping bug to enable boot wait. one is available at: ftp://ftp.linksys.com/pub/network/ wrt54gs_3.37.2_us_code.zip n download and unzip this file. n plug an ethernet patch cable into link #1 on the router (not the wan port) and the interface on your machine. set the ip address of your computer to a static ip address in the 192.168.1.x range, not 192.168.1.1, which is used by the router. n log into router by opening a browser window and putting 192.168.1.1 into the address bar. (note: this is only for factory preset routers.) username: (leave blank) password: admin n click on "administration". n click on "firmware upgrade". n click "browse" and locate the old linksys firmware on your machine. n click "upgrade". n wait patiently while it flashes the firmware…. n click "setup". n click "basic setup". public libraries and internet access | jaeger, bertot, mcclure,

sure that the line for "boot_wait" is set to on n unplug the router (the linksys router will only look for new firmware on boot). n use tftp on your linux or windows machine. n if the openwrt0­wrt54gs­squashfs.bin file is not in this directory, copy the file to this directory n run the following commands at the prompt (below are the linux commands) tftp 192.168.1.1 tftp> binary

is head of digital programs and services, louisiana state university libraries. prior to this position, ziegler was the head of digital scholarship and technology, american philosophical society. richard shrake (shraker13@gmail.com) is a library technology consultant based in burlington, vermont. abstract book-recommendation systems are increasingly common, from amazon to public library interfaces. however, for archives and special collections, such automated assistance has been rare. this is partly due to the complexity of descriptions (finding aids describing whole collections) and partly due to the complexity of the collections themselves (what is this collection about and how is it related to another collection?). the american philosophical society library is using circulation data collected through the collectionmanagement software package, aeon, to automate recommendations. in our system, which we’re calling pal (people also liked), recommendations are offered in two ways: based on interests (“you’re interested in x, other people interested in x looked at these collections”) and on specific requests (“you’ve looked at y, other people who looked at y also looked that these collections”). this article will discuss the development of pal and plans for the system. we will also discuss ongoing concerns and issues, how patron privacy is protected, and the possibility of generalizing beyond any specific software solution. introduction the american philosophical society library (aps) is an independent research library in philadelphia. founded in 1743, the library houses a wide variety of material in early american history, history of science, and native american linguistics. the majority of the library’s holdings are manuscripts, with a large amount of audio material, maps, and graphics, nearly all of which are described in finding aids created using encoded archival description (ead) standards. like similar institutions, the aps has long struggled to find new ways to help library users discover material relevant to their research. in addition to traditional in-person, email, and phone reference, the aps has spent years creating search and browse interfaces, subject guides , and web exhibitions to promote the collections.1 as part of these ongoing efforts to connect users with collections, the aps is working on an automated recommendation system to reuse circulation data gathered through aeon. developed by atlas systems, aeon is a “request and workflow management software specifically designed for special collections libraries and archives,” and it enables the aps to gather statistics on both the use of our manuscript collections and on aspects of the library’s users.2 the automated recommendation system, which we’re calling pal, for “people also liked,” is an ongoing effort. this article presents a snapshot of current work. pal: toward a recommendation system for manuscripts | ziegler and shrake 85 https://doi.org/10.6017/ital.v37i3.10357 literature review the benefits of recommendations in library opacs has long been recognized. writing in 2008 about the library recommendation system bibtip, itself started in the early 2000s, mönnich and spiering observe that “library services are well suited for the adoption of recommendation systems, especially services that support the user in search of literature in the catalog.” by 2011 oclc research and the information school at the university of sheffield began exploring a recommendation system for oclc’s worldcat.3 recommendations for library opacs commonly fall into one of two categories, content-based or collaborative filtering. content-based recommendations pair specific users to library items based on the metadata of the item and what is known about the user. for example, if a user indicates in some way that they enjoy mystery novels, items identified as mystery novels might be recommended to them. collaborative filtering combines users in some way and creates recommendations for one user based on the preferences of another user. there can be a dark side to recommendations. the algorithms that determine which users are similar and thus which recommendations to make are not often understood. writing about algorithms in library discovery systems broadly, reidsma points out that “in librarianship over the past few decades, the profession has had to grapple with the perception that computers are better at finding relevant information then people.”4 the algorithms that are doing the finding, however, often carry the same hidden biases that their programmers have. reidsma encourages a broader understanding of algorithms in general and deeper understanding of recommendation algorithms in particular. the history of recommendation systems in libraries has informed the ongoing development of pal. we use both the content-based and the collaborative filtering approach to offering recommendations to users. for the purposes of communicating them to nontechnical patrons, we refer to them as “interest-based” and “request-based,” respectively. furthermore, we are cautious about the role algorithms play in determining which recommendations users see. our help text reinforces the continued importance of working directly with in-house experts, and we promote pal as one tool among the many offered by the library. we are not aware of any literature on the development of recommendation tools for archives or special-collections libraries. the nature of the material held in these institutions presents special challenges. for example, unlike book collections, many manuscript and archival collections are described in aggregate: one description might refer to many letters. these issues are discussed in detail below. putting data to use: recommendations based on interests and requests the use of aeon allows the aps to gather and store data, including both data that users supply through the registration form and data concerning which collections are requested. pal use both types of data to create recommendations. interest-based recommendations the first type of recommendation uses self-identified research interest data that researchers supply when creating an aeon account. when registering, a user has the option to select from a list of sixty-four topics grouped into seven broad categories (figure 1). the aps selected these information technology and libraries | september 2018 86 interests based on suggestions from researchers as well as categories common in the field of academic history. upon signing in, a registered user sees a list of links (figure 2); each link leads to a full-page view of collection recommendations (figure 3). these recommendations follow the model, “you’re interested in x, other people interested in x looked at these collections.” request-based recommendations using the circulation data that aeon collects, we are able to automate recommendations in pal based on request information. upon clicking a request link in a finding aid, the user is presented with a list of recommendations on the sidebar in aeon (figure 4). each link opens the finding aid for the collection listed. figure 1. list of interests a user sees when registering for the first time. a user can also revisit this list to modify their choices at any point by following links through the aeon interface. the selected interests generate recommendations. pal: toward a recommendation system for manuscripts | ziegler and shrake 87

item from a finding aid. the process currently, the data that drives these two functions is obtained from a semidynamic process via daily, automated sql query exports. usernames are employed to tie together requests and interests but are subsequently purged from the data before the results are presented to users and staff. this section explains the process in detail and presents code snippets where available. all code is available on github.5 interest-based recommendations for interest-based recommendations, we employ two queries. the first query pulls every collection requested by a user for each topic for which that user has expressed an interest. the second aggregates the data for every user in the system. the following queries get data from the microsoft sql database, via a microsoft access intermediary, that aeon uses to store data. because of the number of interest options in the registration form, and the character length of some of them (“early america colonial history,” for example) we encode the interests in shortened form. “early america colonial history” becomes “ea-colhist” so as not to run into character limits in the database. this section explores each of these queries in more detail and provides example code. pal: toward a recommendation system for manuscripts | ziegler and shrake 89 https://doi.org/10.6017/ital.v37i3.10357 the first query gathers research topics for all users who are not staff (user status is ‘researcher’), and where at least one research topic is chosen (‘researchtopics’ is not null). the data is exported into an xml file that we call “aeonmssreg.” select aeondata.dbo.users.researchtopics, aeondata.dbo.transactions.callnumber, aeondata.dbo.transactions.location from aeondata.dbo.transactions inner join aeondata.dbo.users on (aeondata.dbo.users.username = aeondata.dbo.transactions.username) and (aeondata.dbo.transactions.username = aeondata.dbo.users.username) where (((aeondata.dbo.users.researchtopics) is not null) and ((aeondata.dbo.transactions.callnumber) like 'mss%' or (aeondata.dbo.transactions.callnumber) like 'aps.%') and ((aeondata.dbo.users.status)='researcher')) for xml raw ('aeonmssreq'), root ('dataroot'), elements; the second query combines all data for all users and exports an xml file ‘aeonmssusers.’ select distinct aeondata.dbo.users.researchtopics, aeondata.dbo.transactions.callnumber, aeondata.dbo.transactions.location, aeondata.dbo.transactions.username from aeondata.dbo.transactions inner join aeondata.dbo.users on (aeondata.dbo.users.username = aeondata.dbo.transactions.username) and (aeondata.dbo.transactions.username = aeondata.dbo.users.username) where (((aeondata.dbo.users.researchtopics) is not null) and ((aeondata.dbo.transactions.callnumber) like 'mss%' or (aeondata.dbo.transactions.callnumber) like 'aps.%') and ((aeondata.dbo.users.status)='researcher')) for xml raw ('aeonmssusers'), root ('dataroot'), elements; each query produces an xml file. these files are parsed using xsl stylesheets into subsets for each research interest. the stylesheets also generate counts of users requesting a collection and number of total requests for a collection by users sharing an interest. an example is the following stylesheet for the topic “early america colonial history,” which pulls from the xml file “aeonmssreg”: <xsl:template match="dataroot"> <xsl:result-document method="xml" href="aeonmssreqparsed.xml"> <collections> <interest name='early america-colonial history' code='ea-colhis'> <xsl:for-each select="aeonmssreq"> <xsl:if test="contains(researchtopics, 'ea-colhis')"> <xsl:if test="location != ''"> <item> <callnumber> <xsl:value-of select="callnumber" /> </callnumber> <location> <xsl:value-of select="location" /> </location> </item> </xsl:if> </xsl:if> </xsl:for-each> </interest> information technology and libraries | september 2018 90 this process is repeated for each interest. the data from the query that we modify with xslt is presented as html that we insert into aeon templates. this html includes the collection name (linked to finding aid), call number, number of requests, and number of users in a table. see figure 3 for how this appears to the user. the following shows how xsl is wrapped in html. <p>the collections most frequently requested from researchers who expressed an interest in <b><xsl:value-of select="@name"/></b> are listed below with links to each collection's finding aid and the number of times each collection has been requested.</p> <table class="rec-table"> <tr> <th>collection</th> <th>call number</th> <th># of requests</th> <th># of users</th> </tr> <xsl:for-each select="record"> <tr> <td> <a href="http://www.amphilsoc.org/collections/view?docid=ead/{callnumber}-ead.xml" target="new"> <xsl:value-of select="collection"/> </a> </td> <td> <xsl:value-of select="callnumber"/> </td> <td> <xsl:value-of select="requests"/> </td> <td> <xsl:value-of select="users"/> </td> </tr> </xsl:for-each> </table> to ensure a user only sees the links that match the interests they have selected, we use javascript to determine the expressed interests of the current user and display the corresponding links to the html pages in a sidebar. this approach works well, but we must account for two quirks. the first is that many interests in the database do not conform to the current list of options because many users predate our current registration form and wrote in free-form interests. secondly, aeon stores the research information as an array rather than in a separate table, so we must account for the fact that the aeon database contains an array of values that includes both controlled and uncontrolled vocabulary. first, we set the array as a variable so we can look for a value that matches our controlled vocabulary and separate the array into individual values for manipulation: // use var message to check for presence of controlled list of topics var message = "<#user field='researchtopics'>"; // use var values to separate topics that are collected in one string var values = "<#user field='researchtopics'>".split(","); pal: toward a recommendation system for manuscripts | ziegler and shrake 91 https://doi.org/10.6017/ital.v37i3.10357 we also create variables to generate the html entries and links out when we have extracted our research topics: var open = "<ul id='navrec'><li class='active'><a href= '?action=10&form=20&value=topic"; var middle = "'>because you are interested in <strong>"; var close = "</strong></a></li></ul>" next we set a conditional to determine if one of our controlled vocabulary terms appears in the array: //determine if user has an interest topic from the controlled list if ((message.indexof("ea-colhis") > -1) || (message.indexof("ea-amrev") > -1) || (message.indexof("ea-earlynat") > -1) || (message.indexof("ea-antebellum") > -1) || … if the array contains a value from our controlled vocabulary, we generate a link and translate our internal code back into a human-friendly research topic (“ea-colhist,” for example, becomes once again “early american colonial history”): for (var i = 0; i < values.length; ++i) { if (values[i]=="ea-colhis"){ document.getelementbyid("topic").innerhtml += (open + values[i] + middle + "early america-colonial history" + close);} else if (values[i]=="ea-amrev"){ document.getelementbyid("topic").innerhtml += (open + values[i] + middle + "early america american revolution" + close);} else if (values[i]=="ea-earlynat"){ document.getelementbyid("topic").innerhtml += (open + values[i] + middle + "early america early national" + close);} else if (values[i]=="ea-antebellum"){ document.getelementbyid("topic").innerhtml += (open + values[i] + middle + "early america antebellum" + close);} … see figure 2 for how this appears to the user. users only see the links that correspond to their stated interest. if the array does not contain a value from our controlled vocabulary, we display the research-topic interests associated with the user account, note that we don’t currently have a recommendation, and provide a link to update the research topics for the account. else {document.getelementbyid("notopic").innerhtml = "<p>you expressed interest in: <div class='declared-interests'><#user field='researchtopics'></div></p><p>we are unable to provide a specific collection recommendation for you. please visit <a href='https://aeon.amphilsoc.org/aeon.dll?action=10&form=81'> our user profile</a> page to select from our list of research topics.</p>" } request-based recommendations in addition to interest-based recommendations, pal supplies recommendations based on past requests a user has made. this section details how these recommendations are generated. aeon allows users to request materials directly from a finding aid (see figure 6). to generate our request-based recommendations we employ a query depicting the call number and user of every request in the system and export the results to an xml file called “aeonlikecollections.” information technology and libraries | september 2018 92 select subquery.callnumber, subquery.username, iif(right(subquery.trimlocation,1)='.',left(subquery.trimlocation,len(subquery.trimlocation)1),subquery.trimlocation) as finallocation from ( select distinct aeondata.dbo.transactions.callnumber, aeondata.dbo.transactions.username, iif(charindex(':',[location])>0,left([location],charindex(':',[location])-1),[location]) as trimlocation from aeondata.dbo.transactions inner join aeondata.dbo.users on (aeondata.dbo.users.username = aeondata.dbo.transactions.username) and (aeondata.dbo.transactions.username = aeondata.dbo.users.username) where (((aeondata.dbo.transactions.callnumber) like 'mss%' or (aeondata.dbo.transactions.callnumber) like 'aps.%') and ((aeondata.dbo.transactions.location) is not null) and ((aeondata.dbo.users.status)='researcher'))) subquery order by subquery.callnumber for xml raw ('aeonlikecollections'), root ('dataroot'), elements; we then process the “aeonlikecollections” file through a series of xslt stylesheets, creating lists of every other collection that every user of the current collection has requested. first the stylesheets remove collections that have only been requested once. then we count the number of times each collection has been requested: <collections> <xsl:for-each select="aeonlikecollections"> <xsl:variable name="variable"> <xsl:value-of select="callnumber"/> </xsl:variable> <xsl:if test="((callnumber = following-sibling::*[1]/callnumber) or (callnumber = preceding-sibling::*[1]/callnumber))"> <aeonlikecollections> <callnumber> <xsl:value-of select="callnumber"/> </callnumber> <username> <xsl:value-of select="username"/> </username> <finallocation> <xsl:value-of select="finallocation"/> </finallocation> <count> <xsl:value-of select="count(key('callnumbercount', $variable))"/> </count> </aeonlikecollections> </xsl:if> </xsl:for-each> </collections> we sort on the collection name and username and then re-sort to combine groups of requested collections with users who have requested each collection. <collections> <xsl:for-each-group select="record" group-by="original"> <group name="{current-grouping-key()}"> <xsl:for-each select="current-group()/callnumber"> <xsl:copy-of select="./following-sibling::*[1]"/> <xsl:copy-of select="."/> <xsl:copy-of select="./following-sibling::*[2]"/> </xsl:for-each> </group> pal: toward a recommendation system for manuscripts | ziegler and shrake 93 https://doi.org/10.6017/ital.v37i3.10357 </xsl:for-each-group> </collections> we then create a new xml file that is organized by our collection groupings. the following snippet shows a populated xml file generated by the xslt stylesheet above. <?xml version="1.0" encoding="utf-8"?> <collections> <group name="aps.archives"> <url>mss.497.3.b63c</url> <callnumber>mss.497.3.b63c american council of learned societies … </callnumber> <count>94</count> <url>mss.ms.coll.200</url> <callnumber>mss.ms.coll.200 miscellaneous manuscripts collection … </callnumber> <count>92</count> we use javascript to determine the call number of the user’s current request and display the list of other collections that users who have requested the current collection have also requested. <script> $(document).ready(function() { $.ajax({ type: 'get', url: 'aeonlike_f_final.xml', datatype: 'xml', success: function(xml) { $(xml).find('group[name="<#param name='callnumber'>"]').each(function() { $('.recintro').replacewith('researchers who requested items from the collection <b><#param name='callnumber'></b> also requested materials from the following collections:'); $('.read-more').append('see more'); $(this).find('url').each(function() { $('#collections').append( '<li><a href="http://amphilsoc.org/collections/view?docid=ead/' + $(this).text() + '-ead.xml" target="_blank">' + $(this).next().text() +'</a> ' ); }) }); } }); }); </script> see figure 4 for how these links appear to the user. all of the exports and processing are handled automatically through a daily scheduled task. the only personally identifiable data that is contained in these processes are usernames, which are used for counting purposes, but they are removed from the final products through the xslt processing on an internal administrative server, are never stored in the aeon web directory, and are never available for other library users or staff to see. potential pitfalls and what to do about them pal allows us to see new things about our users, and we hope that our users are able to see new collections in the library. however, there are potential pitfalls to the way we’ve been working on this project. we’re calling the two biggest pitfalls the “bias toward well-described collections” and the “problem of aboutness.” information technology and libraries | september 2018 94 the bias toward well-described collections the bias toward well-described collections is best understood by examining how the aps integrates aeon into our finding aids. we offer request links at every available level of description: collection, series, folder, and item. if a patron spends all day in our reading room and looks at the entirety of an item-level collection, they could have made between twenty and one hundred individual requests from that collection. for our statistics, each request will be counted as that collection being used. figure 6 shows a collection described at the item level; each item can be individually requested, giving the impression that this collection is very heavily used even if it is only one patron doing all the requesting. figure 6. finding aid of collection described at the item level. a patron making their way through this collection could make as many as one hundred individual requests. for collections described at the collection level, however, the patron has only one link to click to see the entire collection. for pal, however, it looks like that collection was only used once, as shown in figure 7. a patron sitting all day in our reading room looking at a collection with little description might use the collection more heavily than a patron clicking select items in a well-described collection. however, when we review the numbers, all we see is that the well-described collections get more clicks. pal: toward a recommendation system for manuscripts | ziegler and shrake 95 https://doi.org/10.6017/ital.v37i3.10357 figure 7. screenshot of finding aid with only collection-level description. this collection has only one request link, the “special request” link at the top right. a patron looking through the entirety of this collection will only log a single request from the point of view of our statistics. the problem of aboutness when we speak of the problem of aboutness, we draw attention to the fact that manuscript collections can be about many different things. one researcher might come to a collection for one reason, another researcher for another reason. a good example at the aps library is the william parker foulke papers.6 this collection contains approximately three thousand items and represents a wide variety of the interests of the eponymous mr. foulke. he discovered the first full dinosaur skeleton, promoted prison reform, worked toward abolition, and championed arctic exploration. a patron looking at this collection could be interested in any of these topics, or others. pal, however, isn’t able to account for these nuances. if a researcher interested in prison reform requests items from the foulke papers, they’ll see the same suggestion as a researcher who came to the collection for arctic exploration. what to do about this identifying these pitfalls is a good first step to avoiding them, but it’s only a first step. there are technical solutions, and we’ll continue to explore them. for example, the bias toward welldescribed collections is mitigated by showing both the number of requests and the number of users who have requested from a collection (see figure 3). we hope that by presenting both numbers, we move a little toward overcoming this bias. however, we’re also interested in the nontechnical approaches to these issues. as mentioned in the introduction, the aps relies heavily on traditional reference service, both remote and in-house. nontechnical solutions acknowledge the shortcomings of any constructed solution and injects a healthy amount of humility into our work. additionally, the subject guides, search tools, and web exhibitions all form an ecosystem of discovery and access to supplement pal. future steps using data outside of aeon we have begun exploring options for using the recommendation data outside of aeon. one early prototype surfaces a link in our primary search interface. for example, searching for the william information technology and libraries | september 2018 96 parker foulke papers shows a link of what people who requested from this collection also looked at. see figures 8 and 9. generalizing for other repositories there are ways to integrate the use of aeon with ead finding aids. the systems that the aps has developed to collect data for automated recommendations takes advantage of our infrastructure. we’d like for other repositories to be able to use pal. it is our hope that an institution using aeon in a different way will help us generalize this system. generalizing beyond aeon pal is currently configured to pull data out of the microsoft sql database used by aeon. however, all the manipulation is done outside of aeon and is therefore generalizable to data collected in other ways. because archives and special collections have long-held statistics in different types of systems, we hope to be able to generalize beyond the aeon use case if there is any interest in this from other repositories. integrating pal into aeon conversations with atlas staff about pal have been positive, and there is interest in building many of the features into future releases of aeon. as of this writing, an open uservoice forum topic is taking votes and comments about this integration.7 figure 8. a link in the search returns that leads to recommendations based on finding aid search. clicking on the link “pal recommendations: patrons who used henry howard houston, ii papers also used these collections” will open an html page with a list of links to finding aids. pal: toward a recommendation system for manuscripts | ziegler and shrake 97 https://doi.org/10.6017/ital.v37i3.10357 figure 9. html link of recommended finding aids based on search. conclusion the aps is trying to add to the already robust options for users to find relevant manuscript collections. in addition to traditional reference, web exhibitions, and online search and browse tools, we have started reusing circulation data and self-identified user interests to automate recommendations. this new system fits within the ecosystem of tools we already supply. this is a snapshot of where the pal recommendation project is as of this writing, and we hope to work with other special collections libraries and archives to continue to grow the tool. if you are interested, we hope you reach out. endnotes 1 “subject guides and bibliographies,” american philosophical society, accessed february 27, 2018,

generalizing beyond aeon integrating pal into aeon conclusion endnotes 88 information technology and libraries | june 2006 article title: subtitle in same font author name and second author the concept of digital libraries is familiar to both librarians and library patrons today. these new libraries have broken the limits of space and distance by delivering information in various formats via the internet. since most digital libraries contain a colossal amount of information, it is critical to design more user-friendly interfaces to explore, understand, and manage their content. one important technique for designing such interfaces is information visualization. although computer-aided information visualization is a relatively new research area, numerous visualization applications already exist in various fields today. furthermore, many library professionals are also starting to realize that combining information visualization techniques and current library technologies, such as digital libraries, can help library users find information more effectively and efficiently. this article first discusses three major tasks that most visualization for digital libraries emphasize, and then introduces several current applications of information visualization for digital libraries. a good understanding of user tasks is the foundation of designing useful visualizations. rao et al. defined several specific user tasks of digital libraries and illustrated some existing information-visualization techniques that can be used to enhance these tasks, such as tilebar, cone tree, and document lens.1 the tasks were browsing subsets of sources iteratively, viewing context-of-query match, visualizing passages within documents, rendering sources and results, reflecting time costs of interaction, managing multiple-search processes, integrating multiple search and browsing techniques, and visualizing large information sets. moreover, zaphiris et al. generalized these tasks into three essential ones: searching, navigation, and browsing.2 indeed, most information-visualization projects for digital libraries have emphasized these three tasks. in terms of searching, shneiderman et al. proposed the use of a two-dimensional display with continuous variables to view several thousand search results simultaneously.3 this visualization included two strategies: two-dimensional visualizations, and browsers for hierarchical data sets (implemented by using categorical and hierarchical axes). in combination with a grid display, this visualization let users see an overview by colorcoded dots or bar charts arranged on a grid and organized by familiar labeled categories. users could probe further by zooming in on desired categories or switching to another hierarchical variable. a language-independent document-classification system, completed by liu et al., provided a search aid in a digital-library environment and helped users analyze the search query results visually.4 this system used a vector model to calculate the similarities between documents and a java applet to display the classification to the user. in terms of navigation, there are also a variety of information-visualization applications. the previous example of two-dimensional display developed by shniederman et al. also contained navigation functions.5 another example is hascoet’s map interface applied to a digital library.6 this prototype was associated with summary views in the form of navigation trees and neighbor trees that showed documents related to one focus document. the user interface was composed of maps automatically generated based on the characteristics of documents retrieved and a default configuration. users could also modify the configuration of maps and edit maps (classical operations such as cut, paste, move, delete, save and load a view, and expand a view). as for browsing, the use of dynamic queries is a technique that has been employed for some time. ahlberg and shneiderman’s (1994) filmfinder is an early example.7 users can move several sliders to select query parameters, and the search results change with the movement of the sliders. this tool can help users browse movie records more easily and cognitively. another technique is query previews, proposed by doan et al.8 query previews allows users to rapidly gain an understanding of the content and scope of a digital collection. users are presented with generalized previews of the entire database using only the most salient attributes. when they select rough ranges, they will immediately learn the availability of the data for their proposed query. all these applications provide good examples and paradigms to some recent projects. this paper’s discussion of visualization techniques will be based on these three essential tasks—searching, navigation, and browsing. ■ techniques and applications this section presents several recent information-visualization projects applied to digital libraries. all these applications emphasize searching, navigation, and browsing. gang wan gang wan (wangang11@gmail.com) is science librarian, texas a&m university, college station. visualizations for digital libraries article title | author 89visualizations for digital libraries | wan 89 lvis—digital library visualizer indiana university’s (iu’s) lvis (digital library visualizer) project aims to aid users’ navigation and comprehension of large document sets retrieved from digital libraries. borner et al. developed a prototype of lvis based on the data set in the dido image bank, provided by iu’s department of art history.9 lvis is a good combination of information-retrieval algorithms and visualized-search interface. in the information retrieval and classification stage, it adopts latent semantic analysis (lsa) to automatically extract semantic relationships between images. the lsa output feeds into a clustering algorithm that groups images into several classes sharing semantically similar descriptors. a modified boltzman algorithm is then used to lay out images in space. this section will focus on the interface metaphors used to display the results of this classification. two interfaces have been implemented for lvis. a 2d java applet was used on a desktop computer for details, and a 3d immersible environment for the cave (cave automatic virtual environment). cave is a virtual reality 10’ x 10’ x 10’ theater made up of three rear-projection screens for walls and a down-projection screen for the floor. projectors throw full-color workstation fields (1,280 x 512 stereo) at 120hz onto the screens, giving between 2,000 and 4,000 linear pixel resolution to the surrounding composite image.10 both 2d and 3d interfaces give users access to three levels of detail: they provide an overview about document clusters and their relations; they show how images belonging in the same cluster relate to one another; and they give more detailed information about an image, such as its description or its full-size version. in the cave environment, users can first enter a virtual display theater that stages the digital library as a cyberspace easter island, presenting gateways to specific subject categories established by the previous classification process. borner et al. used 3d icons here to encode subject categories (in this case, they actually used a sculptural form of heads inspired by images of the data set).11 after users “enter” into these head icons, they are transited to a new 3d spatial metaphor that presents images in the current category. these images, or slides from the digital library, are presented in crystalline structures (figure 1). in this environment, each crystal represents a set of images with semantically similar image descriptions. again, physical proximity is used here as a metaphor to encode semantic similarities among images. the formations of the crystalline structures depend on the size of the actual search-result data set. navigation in this space is easy. users can also “walk” through this environment and select images of interest to display a largerand clearer-size version (as two images shown in figure 1). if the larger version is not satisfactory, it can be returned to its previous iconic presentation. uc system: a fluid treemap interface for digital libraries the uc system—the acronym “uc” came from its original (but no longer used) internal name “uplib client”—was developed by good et al. at palo alto research center.12 it was built on the uplib personal digital-library platform, which provides an “extensible, format-agnostic, and secure document-repository layer.”13 “personal” here means that the user already has the right to use all of the data objects in the library, and already has local possession of those objects. however, this visualization can be employed in more general digital libraries. the uc system uses continuous and quantum treemap layouts to present collections of documents. continuous treemaps are space-filling visualizations of trees that assign an area to tree nodes based on the weighting of the nodes.14 in continuous treemaps, the aspect ratio of the cells is not constrained, although square cells are often preferred. quantum treemaps extend this idea by making cell dimensions an even multiple of a unit size.15 the treemap visualizations provide meaningful overviews of document collections and fast, intuitive navigation among multiple documents in a working set. an important aspect of the interface is the fluidity of navigation. this allows the user to focus on the documents rather than on interacting with the tool. the interface allows a user to zoom in on an object with a left-click, and to zoom out when the user clicks on the background; figure 1. lvis: image crystals and panels 90 information technology and libraries | june 2006 however, the combination of a “zoomable” user interface and continuous treemaps leads to a problem: conflicts with aspect ratios. to solve this problem, good et al. proposed to zoom and morph the cell to the window size while leaving the rest of the layout in place.16 thus the visual disturbance of the display is minimized since only a single cell moves. with respect to searching, this system provides several methods to filter results. first, its interface includes a mechanism to search for specific content within the documents. as letters are added to the search query, the system increasingly highlights matching documents to immediately indicate matching documents. secondly, the user can also choose to update the view to display only those documents that match the current query. figure 2 gives an example of a user-initiated query process. in the scenario described in figure 2, the user first enters the search terms (2.1), and interactive highlights then appear for groups with matching documents (2.2). the user presses a button to limit the view to only the matching documents (2.3). finally, the user zooms in on a document and begins reading with an integrated reading tool. (2.4) the uc system also offers a mechanism that allows the user to compare multiple documents. after users retrieve a set of documents through a search, they can press a button to “explode” the documents to pages. they can continue zooming in to a portion of a single document, and then select a document page to read with the integrated reading tool. in short, the uc system uses treemaps as the primary visual metaphor. it also uses various visualization techniques that enhance user interactions, such as zooming, interactively highlighting, exploding, etc. activegraph activegraph is an information-visualization tool designed by marks et al. (2000) at los alamos national laboratory (lanl).17 it aims to provide users with a concise, customizable view of documents in a digital library. in this system, a set of digital-library documents is represented as a data set in a 2d or 3d scatter plot. the data set can represent any digital-library objects in various formats including books, journals, papers, images, and web resources. marks et al. used six visual attributes of the scatter plot: the x-, y-, and z-axes, color, size, and shape to encode the bibliographic information of documents in a digital library, including title, author, date of publication, and number of citations.18 the user can select and adjust these attributes from a control panel on the right-hand side of the screen. thus, activegraph allows users to both view and customize the contents of a digital library. the main visual representation of this tool is a scatter plot. scatter plots have been used to represent large sets of data for a long time. they provide an overview of a data set and show the distribution of data points clearly, revealing clusters and statistical information.19 hence, these scatter plots make it possible for users to perceive meaningful patterns of the data. an example of using activegraph scatter plots to visualize citation data for postdoctoral researchers at lanl is given in figure 3. this scatter plot intends to provide users with information, such as the number of times their papers published between 1998 and 2002 were cited. the visualization is based on the metadata in the lanl digital library. in this scatter plot, the postdoctoral researcher’s last name is mapped to the x-axis and the number of citations is mapped to the y-axis. a pixel of a particular color can provide two pieces of information, for example, by encoding a paper and the subject category of the paper. a group of pixels of a particular size, shape, and color can provide four pieces of information by encoding a paper, the subject category of the paper, whether the paper has been cited, and whether the paper has been read by another user of the collaborative library. from this scatter plot, users can easily learn the citation pattern of these papers. unlike some other scatter plot applications such as homefinder and filmfinder, activegraph uses different filters for queries. instead of filter sliders, it uses filter lists, which consist of selection list boxes, one for each data attribute. these filter lists can provide users with functionality that is important in the context of digital libraries. activegraph allows users to manipulate the display of data in another manner by applying a logarithmic transformation. as some data sets, such as citation data, can frequently have an exponential distribution, the figure 2. the search interface of the uc system article title | author 91visualizations for digital libraries | wan 91 logarithmic transformation can spread the clustered dots more evenly across the scatter plot. other data transformations and visualizations may be important in some cases as well, such as parallel coordinates for displaying citation statistics for the same group of researchers at different points in time. the scatter plot is not a new visualization technique. this example, however, demonstrates that by encoding document attributes and designing proper filters, it can be used in a digital library environment effectively and efficiently. 3d vase museum the previous example, lvis, already introduced the applications of 3d representations in digital libraries. the 3d vase museum developed by shiaw et al. at tufts university is another good example of 3d space metaphor in digital libraries using a variety of visualization techniques.20 in this 3d vase museum, the user can navigate seamlessly from a high level scatter-plot-like plan view to a perspective overview of a subset of the collection, to a view of an individual item, to retrieval of data associated with that item, all within the same virtual room and without any mode change or special command. unlike the traditional digital library, which displays thumbnails and descriptions of vases in the main browser interface, this museum is a 3d virtual environment that presents each vase as a 3d object and places it in a 3d space of a room within a museum. figure 4 gives a wideangle view of this 3d museum. in this view, one wall represents the timeline (year bce) and the adjacent wall represents the types of wares (e.g., red figures, black figures). the user can “walk” through this virtual room and look at the vases. the wide-angle view pictured in figure 4 will then be transited to an eye-level view so that the user can probe the objects more clearly. when the user continues “walking” toward an object of interest, secondary information about this vase will appear in the virtual scene. if the user looks closer, the text information becomes clearer. as the user moves farther and farther away, the information becomes less and less visible until it eventually disappears from the scene. if the user clicks on the vase html page, a version of the original html page will be loaded, from which a 3d model of the vase can be loaded. the user can then rotate this 3d model on the screen using the mouse to see all the aspects of the vase. the 3d vase museum is maintained in the background all times. the user can also navigate the room in a perspective view by switching the view port upward toward the ceiling (watching from upside down). the user can then switch the views between a high-level scatter plot and a 3d perspective view. similarly, in this application, the xand yaxes are mapped to two attributes of the vases: year and ware. with this seamless blend from a high-level data plot to 3d objects, the user can navigate without losing the point of view or context by just moving within the virtual environment. according to shiaw et al., a usability test has been administered, in which tasks based on archaeology courses were designed and subjects were asked to perform these tasks in the original traditional digital library and this 3d museum.21 the results showed subjects who used the 3d vase museum performed the tasks 33 percent better and did so nearly three times faster. ■ collaborative visual interfaces to digital libraries collaborative visual interfaces is an ongoing project led by borner at indiana university (iu). borner et al. (2002) proposed the development of a shared 3d document space for a scholarly community—namely faculty, staff, and students at iu’s school of library and information science.22 the space will provide access to a collection of various online documents including text, images, video, and software demonstrations. a semantic treemap algorithm has been developed to layout documents in a 3d space.23 semantic treemaps utilize the original treemap approach to determine the size (dependent on the number of documents) and layout figure 3. activegraph scatter plot of citation data for papers authored by lanl postdoctoral researchers 92 information technology and libraries | june 2006 of document clusters. subsequently, an algorithm (force directed placement) was applied to the documents in each cluster to place documents spatially, based on their semantic similarity, which was encoded by the physical proximity between two dots. an example of the semantic treemaps is shown in figure 5.1. a 3d space metaphor was then used to display these documents on the desktop interface, as shown in figure 5.2. in this 3d space, each document is represented by a square panel textured by the corresponding web page’s thumbnail image and augmented by a short description such as the web page title that appears when the user moves the mouse over the panel. as in other 3d environments, users can “walk” through this space to probe documents of interest. upon clicking the panel, the corresponding web page is displayed in the web-browser interface. users can collaboratively examine, discuss, and modify (add and annotate) documents, thereby converting this document space into an ever-evolving repository of the user community’s collective knowledge that members can access, learn from, contribute to, and build upon. certain usability studies have been performed to determine the influence of panel size and panel density on retrieval performance. results showed that subjects were slightly faster and more accurate if web-page panels are larger and denser. ■ aquabrowser aquabrowser is a fuzzy visualization tool that shows the high-level description of a conceptual space, hiding irrelevant information and displaying information elements in context.24 it is a generic java applet that can be embedded into any web page. medialab, the developer of aquabrowser, claims that users of aquabrowser can browse through a dynamic conceptual space that is continually reshaped to reflect their interests. animations make transitions from one state to another appear more fluid, showing users why and how the information is rearranged. medialab uses the term “word cloud” as the visual metaphor of the aquabrowser interface. but in fact, the primary visual representation is a network of linked words that are distributed in the conceptual space. the search term that the user assigns will display at the center of this network. the physical distance between another term node and this term encodes the relevancy between these terms. the larger and closer the word is to the center of the screen, the greater its relevance to the search term. in contrast, the smaller and more peripherally positioned, the less relevant it is. each of the user’s actions will change and rearrange the distribution and importance of the words, putting those of greater interest closer to the user and those of less interest nearer to the edge of the screen. it also uses colors to encode attributes of terms, such as spelling variations, visited words, and translations. figure 6 shows an example of a search display. this tool has been used by a number of libraries to enhance their online catalog search interfaces. it could be a very useful search aid in digital libraries as well. ■ summary and trends the above applications are just a few examples of information visualization in a digital-library environment. many other metaphors and techniques, such as perspective wall, cone tree, document lens, and hyperbolic browser, have been used or can potentially be used to facilitate searching, browsing, and navigating through the maze of information in a digital library. the digital library is an interdisciplinary subject involving several research areas such as information retrieval, multimedia information processing, and classification. all these aspects of digital libraries make information visualizations more complicated in this environment. therefore, the systems described in this paper have integrated various visualization techniques. figure 4. a wide-angle overview of the 3d vase museum article title | author 93visualizations for digital libraries | wan 93 the examples in this paper, along with many others, show that the 3d space metaphor has attracted much attention from information-science communities. the combination of 3d space and virtual reality that can be accessed from web browsers these days is becoming a trend of information visualization for digital libraries. this technique gives the user maximum freedom to walk through the library collections, searching and browsing documents. the 3d visual structures, however, have greater implementations compared with those that are 2d, since they require more processing power and include more parameters.25 that is partly why many 2d visualizations developed in the 1990s are still widely used. for example, both activegraph and 3d vase museum have employed 2d scatter plots; both uc system and collaborative visual interfaces have used treemaps. furthermore, it is very important to focus on the actual needs of users. research on any visualization for digital libraries should be based on the detailed analysis of users, their information needs, and their tasks.26 usability tests have been done for some of the above applications, but not for all of them. further research and usability tests are required to determine to what extent a visual interface facilitates the user ’s perception of information. references and notes 1. r. rao et al., “rich interaction in the digital library,” communications of acm 38, no. 4 (1996): 29–39. 2. p. zaphiris et al, “exploring the user

84 digital resource sharing and library consortia in italy tommaso giordano interlibrary cooperation in italy is a fairly recent and not very widespread practice. attention to the topic was aroused in the eighties with the italian library network project. more recently, under the impetus toward technological innovation, there has been renewed (and more pragmatic) interest in cooperation in all library sectors. sharing electronic resources is the theme of greatest interest today in university libraries, where various initiatives are aimed at setting up consortia to purchase licenses and run digital products. a number of projects in hand are described, and emerging trends analyzed. t he state of progress and the details of implementation in various countries of initiatives to share digital information resources obviously depend-apart from current investment policies to develop the information society-on many factors of a historical, social, and cultural nature that have determined the evolution and consolidation of cooperation practices specific to each context. before going to the heart of the specific subject of this article, in order to foster an understanding of the environment in which the trends and problems that we shall be considering are set, i feel it best to give a quick (and necessarily summary) sketch of the library cooperation position in italy. the word "cooperation" became established in the language of italian librarians only toward the mid-'70s, when in the sector of public libraries-which were transferred in those years from central government to local authorities-the "territorial library systems" were taking shape: this was a form of cooperation provided for and encouraged by regional laws that brought together groups of small and medium-sized libraries, often around a system centre supplying shared services. a few years later, in the wake of the new information technologies and in line with ongoing trends in the most advanced countries, in italy, too, the term "cooperation" became increasingly associated with the concept of computerized library networks. the decisive impulse in this direction came from a project of the national library service (sbn), the national network of italian libraries, then in a gestation stage, which also had the merit of tommaso giordano (giordano@datacomm.iue.it) is deputy director of the library at the european university institute, florence. 84 information technology and libraries i june 2000 speeding up the opening of the italian librarianship profession to experiences underway in the most advanced countries_! in the '80s, cooperation, together with automation, was the dominant theme at conferences and in italian professional literature. however, the heat of the debate had no satisfactory counterpart in terms of practical implementation, because of both resistance attributable to a noninnovative administrative culture and the polarization of the bulk of the investments around a single major project (the sbn network), the technical and organizational choices of which were shared by only part of the libraries, while others remained completely outside this programme. many librarians, while recognizing the progress over the last fifteen or twenty years (including the possibility of accessing the collective catalogue of sbn libraries through the internet), maintain that results obtained in the area of cooperation are well below expectations, or energy involved. i am touching here on one of the most sensitive, controversial points in the ongoing professional debate, which i do not wish to dwell on except to note the split that came in italian libraries following the vicissitudes of a project that ought, instead, to have united them and stimulated large-scale cooperation.2 i shall now seek to summarize the cooperation position in italy in relation to the subject of this article. very schematically (and arbitrarily) i have grouped the experiences i feel most signficant under three heads: sbn network, territorial library systems, and sectoral cooperation. sbn brings together some eight hundred large, medium-sized, and small libraries (national, localauthority, university, and research-institute). the programme, funded by the central government, supports cooperation in the following main sectors: • hardware sharing, • development and maintenance of library software packages, • network administration, • shared cataloguing, and • interlibrary loans. the sbn is a star network with its central node consisting of a database (the so-called "index") containing the collective catalogue of the participating libraries (currently some four million relevant bibliographic titles and 7.5 million locations). to the index are linked the thirtyseven local systems, single libraries or multiple libraries, that apply the computerized procedures developed by the sbn programme. thus the sbn is a closed network of only those libraries agreeing to adopt the automation systems distributed by the central institute for the union catalogue, the central office coordinating the programme, take part. reproduced with permission of the copyright owner. further reproduction prohibited without permission. from the organizational viewpoint, the sbn can be regarded as a de facto consortium (i.e., not in the legal sense of the term), even if the management bodies, participation structures, and funding mechanisms differ considerably from consortia that have been set up in other countries. in fact, libraries join the sbn through an agreement among state, regions, and universities, and the governing bodies represent not the libraries but their parent institutions. participating libraries receive the services free, and funding for developing the systems and network administration comes from the central government, which coordinates the technical level of the project through iccu.3 currently, ideas are moving toward evolving the sbn into an open network system and reorganizing its management bodies: if this provision becomes a reality, the sbn will have potential for taking on an important role in developing digital cooperation. the territorial library systems, developed especially in the central and northern regions, consist of small groups of public libraries cooperating in one or more sectors of activity such as: • sharing computer systems, • cataloguing, • centralized management of purchases, • interlibrary loans, and • professional training and other activities. the library systems are based on conventions and formal or informal agreements between local institutions (the municipalities) and receive support from the provincial and regional administrations. in more recent years some systems (e.g., abano terme, in the veneto) have formed themselves into formal, legal consortia. the most advanced experience in this sector-for example, the libraries in the valseriana (an industrial valley in lombardy), which have been operating on the basis of an informal consortium for some twenty years now-have reached a high level of efficiency comparable with the most developed european situations and may rightly be regarded as reference models for the organization of cooperation. however, given their limited size, they are unlikely to achieve economies of scale in the digital context unless they develop broader alliances. it is not unlikely that these consortia, given their capacity to work together, will in the near future develop broader forms of cooperation suited to tackling current technological challenges. sectoral cooperation (cooperation by area of specialization) is meeting today with steadily increasing interest, though it did not fare very well in the past. among the rare initiatives embarked upon by university and research libraries in this direction, particular importance in our context attaches to the national coordination of architectural libraries (cnba), started some twenty years ago, which became an association in 1991. the cnba has various projects on its programme and can be regarded as an established reference point for cooperation among architectural libraries. we should also mention one of the "oldest" cooperation projects among research libraries: the italian periodicals catalogue promoted by the national research council (cnr), recently made available online by the university of bologna.4 to complete this sketch, at least a mention should be made of the participation of italian libraries in the european commission's technical programme in favor of libraries. this programme, which since 1991 has mobilized the world of libraries in the european union, not only favors and guides explosion of technologies into libraries in accordance with preset objectives, but also has the aim of encouraging cooperation among libraries in the various countries. the programme-the latest edition of which includes not just libraries but also archives and museums-has secured significant participation from many italian libraries. over and above the validity of the projects already carried out or under way (important as that is), this programme has been very valuable to italian libraries in terms of exchanges of experience and of opening up professional horizons, especially as regards cooperation practice.s digital cooperation recently, following the expansion of electronic publishing, university libraries have been displaying renewed interest in cooperation activities with particular reference to acquiring licenses and sharing electronic resources. this movement is at present in full swing and is giving rise to manifold cooperation initiatives. to get an idea of the trends under way, one may leaf through a session on database networking in italian universities in the proceedings of the aib congress at genoa. 6 on that occasion a group of universities presented a "draft proposal of agreement on access to electronic information." the document is divided into two parts, the first defining the purposes and object of university cooperation in the sphere of electronic information. the second part indicates operational objectives for cooperation in acquiring electronic information and proposes a model contract for purchasing licenses, to which member universities are to keep. the content of this second part coincides with the recommendations and understandings signed by associations, consortia, and groups of libraries in other countries, and largely follows the indications and recommendations issued by the european bureau of library information and documentation associations (eblida), the organization that brings together the library associations of the various european countries; by digital resource-sharing and library consortia in italy i giordano 85 reproduced with permission of the copyright owner. further reproduction prohibited without permission. the international coalition of library consortia (icolc); and by other library organizations. there is no point here in listing all initiatives under way in italian libraries, in part because most of them are only just started or in the experimental stage. i shall mention a few only to bring out the trends that seem, from my point of view , to be emerging . development of digital collections at the moment initiatives in this sector are much fewer and less substantial than in other industrialized countries. among them the biblioteca telematica italiana stands out: in it, fourteen italian and two foreign universities digitize , archive, and put online works in italian . the project is based on a consortium, the italian interuniversity library center for the italian telematic library (cibit), supported by funds from the national research council (cnr) and made up of the fourteen italian and two foreign universities that have signed the agreement. technical support is provided by the cnr institute for computer linguistics, located in pisa.7 in this context we must also note, especially for the consequences it may have for the future growth of digital collections, an agreement between the national central library in florence and the publishers and authors associations aimed at accomplishing the national legal depository for electronic publishing project, which also provides for production of a section of the italian national bibliography to be called bnidocumenti elettronici. the publishers who have signed the agreement undertake to supply a copy of their electronic products to the national central library in florence. the latter undertakes to guarantee conservation of the electronic products deposited, and to make them accessible to the public in accordance with the agreements reached. • description of electronic resources in this area the bulk of the initiatives are still in an embryonic stage. in the sector of periodicals index production (i.e., tocs), mention should be made of the economic social science periodicals (essper), a cooperation project on italian economics periodicals launched by the libero istituto universitario carlo cattaneo (castellanza, varese) to which some forty libraries are contributing. 9 recently the project has been extended to italian legal journals. essper is a cooperative programme based on an informal agreement among the libraries, each of which undertakes to supply in good time the tocs of the periodical titles they have undertaken to monitor. the programme does not benefit from any outside funds, being supported entirely by the participating libraries, which 86 information technology and libraries i june 2000 have recently been endeavouring to evolve into a more structured form of cooperation . administration of electronic resources and licenses in this sphere there have been numerous initiatives recently, particularly by university libraries . one may note, first, a certain activism by university data-processing consortia (big computing centres created at the start of the computer era to support applications in scientific and then university and library administration areas). the interuniversity consortium for automation (cilea) in milan , which has for some time been operating in the area of library systems and electronic information distribution (especially in the biomedical sector), has extended its activities by offering services to nonmembers of the consortium too. recently cilea, in connection with a broader programme---cdl-cilea digital library-has been negotiating with a number of major publishers the distribution of electronic journals and online bibliographic services on the basis of needs expressed by the libraries in the consortium. caspur (the university computing consortia in rome) is working on several projects, among them shared management of electronic resources on cd-rom in a network among five universities of the centre-south . caspur, too, has opened its services to libraries not in the consortium and is negotiating with a number of major publishers the licenses for establishing a mirror site for electronic periodicals. the university of genoa, through csita, its computing services centre, has concluded an agreement with an italian distributor of electronic services to enable multisite license-sharing for biomedical databases by institutions operating on the territory of liguria. very recently the universities of florence, bologna, modena, genoa, and venice and the european university institute in florence have initiated a pilot project (cipe) for shared administration of electronic periodicals, and have begun negotiations with a number of publishers. let us now seek to draw some conclusions from this initial, brief consideration of current initiatives: • initiatives in the area of digital cooperation are coming mainly from the world of university and research-institute libraries. • no projects are big enough to achieve economies of scale, with most initiatives in hand having a very limited number of partners and often being experimental in nature . • projects under way do not provide for the formation of proper consortia, most likely because the legal form of the consortium is hard to set up in italy because of the burdens involved, especially the complexity and length of the decision-making processes needed to constitute such an organization. reproduced with permission of the copyright owner. further reproduction prohibited without permission. • librarians prefer decentralized forms of cooperation, partly because , shaken by experiences of the past, they fear losing autonomy and efficiency and finding themselves caught up in the bureaucracy of centralized organizations. "however, there can also be a correlation between the amount of autonomy that the individual institution retains and the ability of the consortium to achieve goals as a group". this observation by allen and hirshon obviously holds for italy too . jo it is no coincidence , in fact, that university computing consortia, who have centralized staff and funds available, are able to carry out more incisiv e actions in this sector. • except for the biblioteca telematica italiana, no initiatives seem to have been incentivized by ad hoc government programmes or funds. • a part of the cooperation projects concerns sharing of databases on cd-roms. the traditional italian resistance to online materials would seem to be due partly to the still inadequate network infrastructures in our country; improvements in this sector might bring a quick turnaround here. • some initiatives in hand have been inspired more by suppliers than by librarians : the risk is to cooperate in distributing a particular product, not to enhance libraries' bargaining power. without wishing to deny anything to the suppliers, who today play an essential part in terms of professional information too, i feel that keeping the roles clearly separate may help to develop clear, upright and mutually advantageous cooperation. • some major project s are being led by universit y computing consortia that have begun to take an interest in the library sector. the university computing consortia would indeed have some of the requirements to play a first-rank role in this sphere if they can manage to bring themselves into their most natural position, i.e., to operate as agents of libraries rather than as distributors of services on behalf of the commercial suppliers. moreover, it ought to be clear that th e computing consortia should act as partners with the library consortia and not as substitutes for them, otherwise the libraries risk limiting their autonomy of decision . • some attention is turning toward university electronic publishing , though at the present stage it does not seem there are practical projects for cooperation in this area. • finally, one has to not e low initiative by libraries (compared with other countries) in developing content and in storing digital collections. th e analysis i have rapidly summarized here is the basis for an initative which has in recent months been stimulating the debate on digital cooperation in italy. i am referring to the italian national forum on electronic information resources (infer), a coordination group initially promoted by the europ ean university institut e, the university of florence, and a number of universities in the centre-north, which is today extending beyond the sphere of university and research libraries. the forum's chief mission is to coop erate to promote efficient use of electronic information reso urce s and facilitate access by the public. to this end it encourages libraries to set up consortia and other typ es of agreement on acquisition and management of electronic resources and access to them . infer's objectives can be summarized as follows: • to act as a reference and linkage point and develop initiatives to promote activities and programmes in the area of library e lectro nic resource sharing; • to enhance awar eness both at institutional political levels (ministries, universities, local authorities, etc.) and among librarians and end users; • to facilitate dialogue and mutual collaboration between libraries and all others in the knowledge production and distribution chain, to help them all (authors, publi shers, intermediaries, end users) to take advantage of the opportunities offered by the information society; and • to maintain contacts with similar initiatives under way in other countries. infer has immediately embarked on a rich programme of activities which is giving appreciable results especia lly in terms of raising awareness of the problem and coordinating initiativ es in the area. we shall her e briefly mention some of the actions in hand that seem to us most important. dissemination of information. infer has developed a web site where as well as information on the forum's activities, important information and documents can be found relating to the consortia, the negotiations and licenses, and in general the digital resource-sharing programmes in italy and around the world.1 1 a discussion list for tnfer members has also been activated. seminars and workshops. thi s activity is aimed at further exploration of themes of particular interest (e.g ., legal aspects of license contracts, or programmes under way in other countries) . data collection. the two main programmes corning und e r this heading are: (a) monitoring of italian cooperation initiatives under way in the digital sector; and (b) collecting data on acquisitions of electronic information resources in university libraries . this information will enable the libraries to have a more exact picture of the situation , so as to assess their bargaining power and achieve the necessary support to adopt the most appropriate strategies. digital resource-sharing and library consortia in italy i giordano 87 reproduced with permission of the copyright owner. further reproduction prohibited without permission. indications and recommendations. as well as translating and distributing documents from the most important associations operating in this area (such as eblida, icolc, and ifla), infer is developing a model license for the italian consortia. infer was set up in may 1999 and currently has some forty members, most of them representatives of university library systems, university computing consortia or research libraries, or univer si ty professors. one of infer's aspirations is to persuade decision-makers to develop a programme of incentives on a national scale for the creation of library consortia . i critical factors as to the delay we note in terms of shared management of electronic resources, weight clearly attaches to the fact that cooperation is not very established , nor are the national structures that ought to have supported it. it would be all too easy and perhaps also more fun to attribute this situation to the so-called individualism of italians and to abandon inquiry into th e structural limitations that may have determined it. first of all, except in very few cases, libraries have no administrative autonomy, or only very little, and with hardly any decision-making powers. this factor favors interference in decision-making processes, complicates th em, slows down procedures, and strips librarians of their responsibility. one of the reasons why the sbn has not managed to generate cooperation is to be sought in the mechanisms for joining and participating in the programme . in other words, many libraries have joined the sbn following decisions taken from above, at the political and admistrative levels, and not on the basis of an autonomous, weighted assessment of attitudes, needs, and alternatives. these experiences have augmented libraries' reluctance to embark on centrally steered national programmes. on the other hand, the low administrative autonomy they have prevents them from implementing truly effective alternative solutions, i.e., ones able to realize economies of scale. another factor is the administrative fragmentation of libraries . the big universities have fifty or so libraries each (often one per department). some universities have an office coordinating the librari es , but only in very few cases does this structure have the powers and the necessary support to coordinate; more often it acts as a mediation office with no real administrative powers. in short, the result is that since (perhaps also because of a misunderstood sense of departmental autonomy) there is no 88 information technology and libraries i june 2000 decision-making centre for libraries in each university , decisional processes prov e slow and cumbersom e. clearly, all this brings many probl ems in establishing understandings and cooperative programmes with other libraries and weakens the universities in negotiating licenses. this position, while objectively favoring suppliers in the short term, in the long term risks facing them with difficulties given an increasingly impoverished, uncertain market because of the fragmentation and the limited capacity of possible purchasers . another limit is the insufficient awareness, especially on the academic side, of the challenges of electronic information. in early 1999 the french daily le monde published an extensive feature on scientific publishing, showing how current publishing production mechanisms, whil e assuring a few big publishers of ample profit margins, are suffocating libraries and universities under the continu ous rises in prices for scientific joumals.12 the argument, immediately taken up by the spanish el pais and other european newspapers, met with very little response in italy. clearly, in italy today, the conditions do not exist to embark on initiatives like the incisive open letter to publishers sent by the kommission des deutschen bibliotheksinstituts filr erwerbung und bestandsentwicklung in germany, supported by similar swiss, austrian, and dutch organizations. 13 the lack of an adequate national policy in the area of electronic information is probably the direct consequence of the problems i have just mentioned. in this context, however praiseworthy the initiatives, they tend in the absence of reference points and practical support to break up or fritter away . under the ministry for universities there are no leadership or action bodies in the area of academic information, like the joint information system committee in britain that stimulates programmes aimed at developing and utilizing information technologies in university and research libraries . these observations are also valid for the state libraries and public libraries, too, where the central (ministry for cultural affairs) and regional authorities could play a more effective part in promoting digital cooperation . i conclusions the picture i have presented is not very rosy. however, it does reveal considerable elements of vitality and great er awareness of the problems emerging, starting with a few representatives of academic sectors who might be able to wield influence and bring about a turnaround. at the moment, the consortium movement to share electronic resources chiefly involves university libraries, reproduced with permission of the copyright owner. further reproduction prohibited without permission. but a few initiatives by public libraries are starting to appear, especially in the multimedia products sector. no specific lines of action are yet emerging at the level of the national authorities-especially the ministry for education and research and the ministry of cultural activities, on which the national libraries and many research libraries depend. it is likely that in the near future the entry of these agencies may be able to modify the current scenario and considerably influence the approach to cooperation. from this viewpoint, the impression is that a few consortium initiatives that have been flourishing in recent months on the part of both libraries and suppliers have the principal aim of proposing cooperation models to guide future choices. in conclusion, we are only at the outset, and the game is still waiting to be played. references

information technology and libraries | june 2018 118 jesi buell (jbuell@colgate.edu) is instruction and design and web librarian and mark sandford (msandford@colgate.edu) is systems librarian at colgate university, hamilton, new york. abstract in 2016, colgate university libraries began converting their static html website to the drupal platform. this article outlines the process librarians used to complete this project using only in-house resources and minimal funding. for libraries and similar institutions considering the move to a content management system, this case study can provide a starting point and highlight important issues. introduction the literature available on website design and usability is predominantly focused on business or marketing websites. what separates library websites from other informational or commercial websites is the complexity of the information architecture—they contain both intricate informational and transactional functions. website managers need to maintain congruity between many interrelated but disparate tools in a singular interface and navigational system. libraries are also often challenged with finding individuals who possess the appropriate skills to build and maintain a secure, accessible, attractive, and easy-to-use website. in contrast to libraries, commercial companies employ a team of designers, developers, content managers, and specialists to triage internal and external issues. they can also spend months or years perfecting a website and, of course, all these factors have great costs associated with them. given that many commercial websites need a team of highly skilled workers with copious time and funding, how can librarians be expected to give their patrons similar experiences to sites like google? this case study will outline how a small team of librarians completely overhauled their fragmented, dreamweaver-based website to a more secure, organized, and appealing open-source platform with drupal within a tight timeline and very few financial consequences. it includes a timeline of major milestones in the appendix. goals and objectives the first necessity for restructuring the colgate university libraries’ website was building a team that had the skills and knowledge necessary to perform this task. the website overhaul was spearheaded by jesi buell, instructional design and web librarian, and mark sandford, systems librarian. buell has a user experience (ux) design and editing background while sandford has systems, cataloging, and server experience. they were advised by web development committee (wdc) members cindy li, associate director of library technology and digital initiatives, and debbie krahmer, digital learning and media librarian. together, the group understood trends in digital librarianship, the needs of the libraries’ patrons, as well as website and catalog design and mailto:jbuell@colgate.edu mailto:msandford@colgate.edu from dreamweaver to drupal | buell and sandford 119 https://doi.org/10.6017/ital.v37i2.10113 maintenance. the first thing the wdc did was outline its goals and objectives, and this documented weaknesses the group wanted to address with a new website. the wdc identified four main improvements colgate libraries needed to make to the website: improve design colgate libraries’ old website suffered from varied design and language use across pages and various tools (libguides, catalog, etc.). this led to an inconsistent and often frustrating user experience and detracted from the user’s sense of a single, cohesive website. the wdc also wanted to improve and update the aesthetic quality of the website. while many of these changes could have been made with an overhaul of the existing site, the wdc would have still needed to address the underlying cause. responsibility for content was decentralized, and content creation relied too heavily on technical expertise with dreamweaver. further, the ad hoc nature of the content—the product of years of “fitting in” content without a holistic approach—meant that changes to visual style could not be accomplished by changing a single css file. there were far too many exceptions to make changes simply. improve usability the wdc needed to make sure all the webpages were responsive and accessible. a restructuring of layout and information architecture (ia) was also necessary to improve findability of resources. on the old site, some content was hidden behind several layers of links. with no platform to ensure or enforce accessibility standards, website managers had to trust that all content creators were conscious of best practices or, failing that, pages had to be re-edited to improve accessibility. improve content creation and governance a common source of library staff frustration was the authoring experience using dreamweaver. there was no way to track when a webpage was changed or see who had made those changes. situations occurred where content was deleted or changed in error, and no one else knew until a patron discovered a mistake. staff could also mistakenly push out outdated versions of pages. it was not an ideal situation, and it was impossible for an individual (the web librarian) to monitor hundreds of pieces of content for daily changes to check for accuracy. the only other option would be narrow access to only those on the wdc, but that would mean everyone had to wait for the web librarian to push content live, which would also be frustrating. beyond the security and workflow issues, many of the library staff felt uncomfortable adding or editing content because dreamweaver requires some coding knowledge (html, css, javascript). therefore, the group wanted to install a content management system (cms) that provided a wysiwyg (what you see is what you get) content editor so that no coding knowledge would be needed. unite disparate sites (website, blog, and database list) under one updated url on a single secure server colgate libraries’ website functionality suffered from what marshall breeding describes as “a fragmented user experience.”1 the libraries website’s main address was http://exlibris.colgate.edu. however, different tools lived under other urls—one for a blog, another for the database list, yet another still for the mobile site librarians had to maintain information technology and libraries | june 2018 120 because the main website was not responsive. additionally, some portions of the website had been set up on other servers because of various limitations in the windows.net environment and inhouse skills. this was further complicated by the fact that most specialized interactivity or visual components had to be created from scratch by existing staff. the libraries’ blog was on an externally hosted wordpress site, and the database a–z list was on a custom-coded php page. a unified domain would make usage statistics easier to track and analyze. additionally, it would eliminate the need for multiple credentials for the various external sites. custom code, be it in php, .net, or any other language, also needs to be regularly updated as new security vulnerabilities arise.2 moving to a well-maintained cms would help alleviate that burden. by establishing goals and objectives, the wdc had identified that it wanted a cms to help with better governance, easier maintenance, and ways to disperse web maintenance responsibilities across library faculty. it was important to choose a cms platform that offered a wysiwyg editor so that content authoring did not require coding knowledge. additionally, the group wanted to update the site’s aesthetic and navigational designs. the wdc also decided that this was the optimal time to introduce a discovery layer (since all these changes would be one entirely new experience for colgate users) rather than smaller, continual changes that would require users to keep readjusting how they used the website. the backend complexity of updating both the website platform and implementing a discovery layer required abundant and detailed planning. however, while there was a lot of overlap in the preparatory work for implementing the discovery layer as well the cms, this article will focus primarily on the cms. planning after the wdc had detailed goals and objectives, and the proposal to update the libraries’ website platform was accepted by library faculty, the group had to take several steps to plan the implementation. the first steps in planning dealt with analysis. content analysis the web librarian conducted a content analysis of the existing website. using microsoft excel to document the pages and the omni group’s omnigraffle to organize the spreadsheet into a diagram, she cataloged each page and the navigation that connected that page to other pages. this can be extremely laborious but was necessary because some content was inherited from past employees over the course of a decade, and no one knew exactly what content was live on the website. this visual representation allowed for content creators to see redundancy in both content and navigation. it also made it easy for them to identify old content and combine or reorder pages. needs analysis the wdc wanted to make sure it considered more than the content creators’ needs. this group surveyed colgate faculty, staff, and students to learn what they would like to see improved or changed. the web librarian conducted several ux studies with both students and faculty, and this elucidated several key areas in need of improvement. from dreamweaver to drupal | buell and sandford 121 https://doi.org/10.6017/ital.v37i2.10113 peer analysis peer analysis involves thoroughly investigating peer institution’s websites to analyze how they organize both their content and their site navigation. it also gives insight into what other services and tools they provide. it is important to choose institutions similar in size and academic focus. colgate university is a small, liberal arts institution that only serves an undergraduate population, so the libraries would not seek to emulate a large university that serves graduate populations or distance learners. peer analysis is an excellent opportunity to see where a website is not measuring up to other websites as well as to borrow ideas from peers to customize for your specific patrons. evaluating platforms now that the group knew what the libraries had and what the libraries wanted from our web presence, it was time to evaluate the available options. this involved evaluating cms products and discovery layer platforms. the wdc researched different cmss and listed positives and negatives. ultimately, the group determined that drupal best satisfied the majority of colgate’s identified needs. a separate committee was formed to evaluate the major discovery-layer services with the understanding that any option could be integrated into the main website as a search box. budgeting as free, open-source software, drupal does not require a subscription or licensing fee. campus it provided a virtual server for the website at no cost to the libraries. budgeting was organized by the associate director of library technology and digital initiatives and the university librarian. money was set aside in case a consultant or developer was needed, but the web and systems librarians were able to execute the conversion from dreamweaver to drupal without external support. if future development support is needed for specific projects, it can be budgeted for and purchased as needed. the last step was creating a timeline defining achievable goals, ownership (who oversees completing the goal and who needs to be involved with the work), and date of completion. timeline the timeline was outlined as follows: october 2015–january 2016 halfway through the fall 2015 semester, the wdc began to create a proposal for changes to be made to the website. this proposal would be submitted to the university librarian for consideration by december 1. in the meantime, the web librarian completed a content inventory, peer analysis, and ux studies. she also gathered faculty and staff feedback on the current website through suggestion-box commentary, one-on-one interviews, online questionnaires, and anecdotal stories. by the deadline for the proposal, this additional information was condensed and presented to the university librarian. after incorporating suggested changes made by the university librarian, the wdc was able to present both the proposal and results from various studies to the library faculty on january 4, information technology and libraries | june 2018 122 2016. at the end of the meeting, the faculty voted to move forward and adopt the proposed changes. february 2016 february was spent meeting with stakeholders, both internal and external to the libraries, to gather concerns, necessary content, and ideas for improvements. the wdc members shared the responsibility of running these meetings. all members from the following departments were interviewed: research and instruction, borrowing services, acquisitions, library administration, cataloging, government documents, information literacy, special collections and university archives, and the science library. together, the wdc also met with members from it and communications. it was vital that these sessions identify several components. first, what content was important to retain on the new site, and why? the act of justification made stakeholders evaluate whether the information was necessary and useful to the libraries’ users. the wdc also asked the stakeholders to identify changes they wanted to see made to the website. the answers ranged from minor aesthetic tweaks to major navigational overhauls. last, it was important to understand how specific changes might impact workflows and functionality for tools outside colgate libraries’ own website. for example, the wdc had to update information with the communications department so that the libraries’ website would be findable on the university’s app. all the answers the wdc received were compiled into a report, and the web librarian used this information to inform design decisions moving forward. march 2016 while the associate director of library technology and digital initiatives coordinated demos from discovery layer vendors, the wdc also met to choose the final template from three options designed by the web librarian. the web and systems librarians also met to create a list of developers in case assistance was needed in the development of the drupal site. the wdc team researched potential developers and inquired about their pricing. the web librarian began to create wireframe templates of the different types of pages and page components (homepage, hours blocks, blogs, forms, etc.). she also began transferring existing content from the old website to the new website. this process, in addition to the development of new content identified by stakeholders, was to be completed by mid-summer. meanwhile, the systems librarian began to consolidate the external sites under drupal to the extent possible. while libguides lives externally to drupal and maintains its own url that the libraries’ website links out to, he was able to bring the database a–z list, blog, and analytics into the drupal platform. this entailed setting up new content types in drupal to accommodate various functional requirements for the a–z list and assist in creating pages to search for and display database information. from dreamweaver to drupal | buell and sandford 123 https://doi.org/10.6017/ital.v37i2.10113 april–may 2016 drupal allows for various models of permissions and authentication. by default, accounts can be created within the drupal system and roles and permissions assigned to individuals as needed. the ldap (lightweight directory access protocol) module allowed us to tie authentication to university accounts and includes the ability to tie drupal permissions to active directory roles and groups. connecting drupal to the university ldap server required the assistance of it infrastructure staff but was straightforward. it staff provided the connection information for the drupal module’s configuration and created a resource account for the drupal module to use to connect to the ldap service. as currently implemented, the ldap module simply verifies credentials and, if a local drupal account does not exist, creates one for the user. permissions for staff are added to accounts after account creation as needed as a part of the onboarding process. permissions in drupal can be highly granular. since one of the goals of the migration to drupal was to simplify maintenance of the website, the wdc decided to begin with a relatively simple, permissive approach. currently, all library staff can edit any page. because of drupal’s ability to track and revert changes easily, undoing a problematic edit is a simple procedure, and because all changes are tied to an individual login, problems can be addressed through training as needed. the wdc discussed a more fragmented approach that tied editing privileges to specific parts of the site but decided against it. the wdc team felt it was better to begin with the presumption of trustworthiness, expecting staff to only make changes to pages they were personally responsible for. additionally, trying to divide the site into logical pieces, then accounting for the inevitable exceptions, would be complicated and time-consuming. the wdc reserved the right to begin restricting permissions in the future, but thus far this has proven unnecessary. july–august 2016 as the libraries ramped up to the official launch, it was crucial to educate the library faculty and staff so they could become independent back-end content creators. both the web and systems librarians held multiple training sessions for the libraries employees so that everyone felt comfortable both editing and generating content. the associate director of library technology and digital initiatives drafted a campus-wide email announcing the new website and discovery layer at this point. it was sent out a month in advance of the official launch. the new website launched in two parts. the soft launch occurred on august 1, 2016. the web and systems librarians set up a link to the new website on the old site so that users could choose between getting acclimated to the new website or using the tool they were used to in the frantic weeks leading up to the beginning of the semester. august 15, 2016, was the official launch. at this point, the http://exlibris.colgate.edu dreamweaver-based website was retired, and it redirected all traffic heading to the old url to the new drupal-based website at http://cul.colgate.edu. because drupal’s url structure and information architecture differed from the old website, the wdc decided that mapping every page on the old site to the new one would be too time consuming. while it was acknowledged that this may cause some disruption (as it would break existing links), it seemed necessary for keeping the project moving forward. library staff updated all external links possible. the google search operator “inurl” allowed us to identify other sites information technology and libraries | june 2018 124 outside the libraries’ control that pointed to the old website. the wdc reached out to the maintainers of those few sites as appropriate. the biggest risk the libraries took by not redirecting all urls to the correct content was the potential to disrupt faculty who had bookmarked content or had direct urls in course materials. however, the wdc team received very few complaints about the new site, and most users agreed that the improvements to the site far outweighed any temporary inconveniences caused by it. if nothing else, the simplified architecture made finding content easier, so direct links and bookmarks became far less important than they once were. implementation and future steps by strictly following the timeline and working closely together, the web librarian and systems librarian were able to launch colgate libraries’ new website in time for the 2016 fall semester. the wdc team was able to pull off this feat within eight months without spending any extra money. the timeline above only gives a high-level view of the steps the wdc took to accomplish this task. the librarians who worked on this project cannot overemphasize the complexity of this endeavor, especially with a small team. however, a website conversion is feasible with organization, time, and with the online support the drupal community provides (especially the community of libraries on the drupal platform). it is also critical to have in-house personnel that have technical (coding and server-side) knowledge, project management knowledge, and information architecture and design knowledge. the response from incoming and returning students and faculty to the updated look and improved usability of the libraries’ digital content was overwhelmingly positive. following best design practices, in january 2017 more ux testing was conducted with student and teaching faculty participants to gauge their reactions to the new website. 3 users overwhelmingly found the new website to be both more aesthetically pleasing and usable than the old website. on the back end, the libraries’ content is now more secure, responsive, and accessible because the libraries are using a cms. library faculty and staff have been able to add or remove content that they are responsible for, but the website can still maintain a consistent look and feel across all pages. governance has been improved exponentially as library staff have been able to easily and quickly contribute to the website’s content without administrative delays. as the team moves forward, the wdc plans to investigate different advanced drupal tools, implementing an intranet, and better leveraging google analytics. as with all library endeavors, improvement requires continued effort and attention. from dreamweaver to drupal | buell and sandford 125 https://doi.org/10.6017/ital.v37i2.10113 appendix: detailed

information retrieval and digital libraries | wan and liu 41 content-based information retrieval and digital libraries this paper discusses the applications and importance of content-based information retrieval technology in digital libraries. it generalizes the process and analyzes current examples in four areas of the technology. content-based information retrieval has been shown to be an effective way to search for the type of multimedia documents that are increasingly stored in digital libraries. as a good complement to traditional textbased information retrieval technology, content-based information retrieval will be a significant trend for the development of digital libraries. w ith several decades of their development, digital libraries are no longer a myth. in fact, some general digital libraries such as the national science digital library (nsdl) and the internet public library are widely known and used. the advance of computer technology makes it possible to include a colossal amount of information in various formats in a digital library. in addition to traditional text-based documents such as books and articles, other types of materials—including images, audio, and video—can also be easily digitized and stored. therefore, how to retrieve and present this multimedia information effectively through the interface of a digital library becomes a significant research topic. currently, there are three methods of retrieving information in a digital library. the first and the easiest way is free browsing. by this means, a user browses through a collection and looks for desired information. the second method—the most popular technique used today—is textbased retrieval. through this method, textual information (full text of text-based documents and/or metadata of multimedia documents) is indexed so that a user can search the digital library by using keywords or controlled terms. the third method is content-based retrieval, which enables a user to search multimedia information in terms of the actual content of image, audio, or video (marques and furht 2002). some content features that have been studied so far include color, texture, size, shape, motion, and pitch. while some may argue that text-based retrieval techniques are good enough to locate desired multimedia information, as long as it is assigned proper metadata or tags, words are not sufficient to describe what is sometimes in a human’s mind. imagine a few examples: a patron comes to a public library with a picture of a rare insect. without expertise in entomology, the librarian won’t know where to start if only a text-based information retrieval system is available. however, with the help of content-based image retrieval, the librarian can upload the digitized image of the insect to an online digital image library of insects, and the system will retrieve similar images with detailed description of this insect. similarly, a patron has a segment of music audio, about which he or she knows nothing but wants to find out more. by using the content-based audio retrieval system, the patron can get similar audio clips with detailed information from a digital music library, and then listen to them to find an exact match. this procedure will be much easier than doing a search on a text-based music search system. it is definitely helpful if a user can search this non-textual information by styles and features. in addition, the advance of the world wide web brings some new challenges to traditional text-based information retrieval. while today’s web-based digital libraries can be accessed around the world, users with different language and cultural backgrounds may not be able to do effective keyword searches of these libraries. content-based information retrieval techniques will increase the accessibility of these digital libraries greatly, and this is probably a major reason it has become a hot research area in the past decade. ideally, a content-based information retrieval system can understand the multimedia data semantically, such as its objects and categories to which it belongs. therefore, a user is able to submit semantic queries and retrieve matched results. however, a great difficulty in the current computer technology is to extract high-level or semantic features of multimedia information. most projects still focus on lower-level features, such as color, texture, and shape. simply put, a typical content-based information retrieval system works in this way: first, for each multimedia file in the database, certain feature information (e.g., color, motion, or pitch) is extracted, indexed, and stored. second, when a user composes a query, the feature information of the query is calculated as vectors. finally, the system compares the similarity between the feature vectors of the query and multimedia data, and retrieves the best matching records. if the user is not satisfied with the retrieved records, he or she can refine the search results by selecting the most relevant ones to the search query, and repeat the search with the new information. this process is illustrated in figure 1. the following sections will examine some existing content-based information retrieval techniques for most common information formats (image, audio, and video) in digital libraries, as well as their limitations and trends.

a&m university, college station, texas. gary (gang) wan and zao liu 42 information technology and libraries | march 200842 information technology and libraries | march 2008 ■ content-based image retrieval there have been a large number of different contentbased image retrieval (cbir) systems proposed in the last few years, either building on prior work or exploring novel directions. one similarity among these systems is that most perform feature extraction as the first step in the process, obtaining global image features such as color, shape, and texture (datta et al., 2005). one of the most well-known cbir systems is query by image content (qbic), which was developed by ibm. it uses several different features, including color, sketches, texture, shape, and example images to retrieve images from image and video databases. since its launch in 1995, the qbic model has been employed for quite a few digital libraries or collections. one recent adopter is the state hermitage museum in russia (www.hermitage. ru), which uses qbic for its web-based digital image collection. users can find artwork images by selecting colors from a palette or by sketching shapes on a canvas. the user can also refine existing search results by requesting all artwork images with similar visual attributes. the following screenshots demonstrate how a user can do a content-based image search with qbic technology. in figure 2.1, the user chooses a color from the palette and composes the color schema of artwork he or she is looking for. figure 2.2 shows the artwork images that match the query schema. another example of digital libraries or collections that have incorporated cbir technology is the national science foundation’s international digital library project (www.memorynet.org), a project that is composed of several image collections. the information retrieval system for these collections includes both a traditional text-based search engine and a cbir system called simplicity (semantics-sensitive integrated matching for picture libraries) developed by wang et al. (2001) of pennsylvania state university. from the front page of these image collections, a user can choose to display a random group of images (figure 3.1). below each image is a “similar” button; clicking this allows the user to view a group of images that contain similar objects to the previously selected one (figure 3.2). by providing feedback to the search engine this way, the user can find images of desired objects without knowing their names or descriptions. simply put, simplicity segments each image into small regions, extracts several features (such as color, figure 1. the general process of content-based information retrieval figure 2.1. a user query figure 2.2. the search results for this query article title | author 43content-based information retrieval and digital libraries | wan and liu 43 location, and shape) from these small regions, and classifies these regions into some semantic categories (such as textured/nontextured and graph/photograph). when computing the similarity between the query image and images in the database, all these features will be considered and integrated, and best matching results will be retrieved (wang et al., 2001). similar applications of cbir technology in digital libraries include the university of california–berkeley’s digital library project (http://bnhm.berkeley.edu), the national stem digital library (ongoing), and virginia tech’s anthropology digital library, etana (ongoing). while these feature-based approaches have been explored over the years, an emerging new research direction in cbir is automatic concept recognition and annotation. ideally, automatic concept recognition and annotation can discover the concepts that an image conveys and assign a set of metadata to it, thus allowing image search through the use of text. a trusted automatic concept recognition and annotation system can be a good solution for large data sets. however, the semantic gap between computer processors and human brains remains the major challenge in the development of a robust automatic concept recognition and annotation system (datta et al., 2005). a recent example of efforts in this field is li and wang’s alipr (automatic linguistic indexing of pictures—real time, http://alipr.com) project (2006). through a web interface, users are able to search images in several different ways: they may do text searches and provide feedback to the system to find similar images. users may also upload an image, and the system will perform concept analysis and generate a set of annotations or tags automatically, as shown in figure 4. the system then retrieves images from the database that are visually similar to the uploaded image. in the process of automatic annotation, if the user doesn’t think the tags given by the system are suitable, he or she can input other tags to describe the image. this is also the “training” process for the alipr system. since cbir is the major research area and has the longest history in content-based information retrieval, there are many models, products, and ongoing projects in addition to the above examples. as image collections become a significant part of digital libraries, more attention has been paid to possibilities of providing content-based image search as a complement to existing metadata search. ■ content-based audio retrieval compared with cbir, content-based audio retrieval (cbar) is relatively new, and fewer research projects on it can be found. in general, existing cbar approaches start from the content analysis of audio clips. an example of this content analysis is extracting basic audio elements, such as duration, pitch, amplitude, brightness, and bandfigure 3.1. a group of random images in the collection figure 3.2. cbir results figure 4. alipr’s automatic annotation feature 44 information technology and libraries | march 200844 information technology and libraries | march 2008 width (wold et al., 1996). because of the great difficulties in recognizing audio content, research in this area is less mature than that in content-based image and video retrieval. although no cbar system has been found to be implemented by any digital library so far, quite a few projects provide good prototypes or directions. one good example is zhang and kuo’s (2001) research project on audio classification and retrieval. the prototype system is composed of three stages: coarse-level audio segmentation, fine-level classification, and audio retrieval. in the first stage, audio signals are semantically segmented and classified into several basic types including speech, music, song, speech with music background, environment sounds, and silence. some physical audio features—such as the energy function, the fundamental frequency, and the spectral peak tracks—are examined in this stage. in the second stage, further classification is conducted for every basic type. features are extracted from the time-frequency representation of audio signals to reveal subtle differences of timbre and pattern among different classes of sounds. based on these differences, the coarse-level segmentation obtained in stage one can be classified to narrower categories. for example, speech can be differentiated into the voices of men, women, and children. finally, in the information retrieval stage, two approaches—query-by-keyword and query-by-example—are employed. the query-by-keyword approach is more like the traditional text-based search system. the query-by-example approach is similar to content-based image retrieval systems where an image can be searched by color, texture, and histogram, and audio clips can be retrieved with distinct features, such as timbre, pitch, and rhythm. this way, a user may choose from a given list of features, listen to the retrieved samples, and modify the input feature set to get more desired results. zhang and kuo’s prototype is a very typical and classic cbar system. it is relatively mature and can be used by large digital audio libraries. more recently, li et al. (2003) proposed a new feature extraction method particularly for music genre classification named daubechies wavelet coefficient histograms (dwchs). dwchs capture the local and global information of music signals simultaneously by computing their histograms. similar to other cbar strategies, this method divides the process of music genre classification into two steps: feature extraction and multi-class classification. the music signal information representing the music is extracted first, and then an algorithm is used to identify the labels from the representation of the music sounds with respect to their features. since the decomposition of audio signal can produce a set of subband signals at different frequencies corresponding to different characteristics, li et al. (2003) proposed a new methodology, the dwchs algorithm, for feature extraction. with this algorithm, the decomposition of the music signals is obtained at the beginning, and then a histogram of each subband is constructed. hence, the energy for each subband is computed, and the characteristics of the music are represented by these subbands. one finding from this research reveals that this methodology, along with advanced machine learning techniques, has significantly improved accuracy of music genre classification (li et al. 2003). therefore, this methodology potentially can be used by those digital music libraries widely developed in past several years. ■ content-based video retrieval content-based video retrieval (cbvr) is a more recent research topic than cbir and cbar, partly because the digitization technology for video appeared later than those for image and audio. as digital video websites such as youtube and google video become more popular, how to retrieve desired video clips effectively is a great concern. searching by some features of video, such as motion and texture, can be a good complement to the traditional text-based search method. one of the earliest examples is the videoq system developed by chang et al. (1997) of columbia university (www.ctr.columbia.edu/videoq), which allows a user to search video based on a rich set of visual features and spatio-temporal relationships. the video clips in the database are stored as mpeg files. through a web interface, the user can formulate a query scene as a collection of objects with different attributes, including motion, shape, color, and texture. once the user has formulated the query, it is sent to a query server, which contains several databases for different content features. on the query server, the similarities between the features of each object specified in the query and those of the objects in the database are computed; a list of video clips is then retrieved based on their similarity values. for each of these video clips, key-frames are dynamically extracted from the video database and returned to browser. the matched objects are highlighted in the returned key-frame. the user can interactively view these matched video clips by simply clicking on the keyframe. meanwhile, the video clip corresponding to that key-frame is extracted from the video database (chang et al. 1997). figures 5.1–5.2 show an example of a visual search through the videoq system. many other cbvr projects also examine these content features and try to find more efficient ways to retrieve data. a recent example is wang et al.’s (2006) project, vferret, a content-based similarity search tool for continuous archived video. the vferret system segments video data into clips and extracts both visual and audio features as metadata. then a user can do a metadata search or article title | author 45content-based information retrieval and digital libraries | wan and liu 45 content-based search to retrieve desired video clips. in the first stage, a simple segmentation method is used to split the archived digital video into five-minute video clips. the system then extracts twenty image frames evenly from each of these five-minute video clips for visual feature extraction. additionally, the system splits the audio channel of each clip into twenty individual fifteensecond segments for further audio feature extraction. in the second stage, both audio and visual features are extracted. for visual features, the color element is used as the content feature. for audio features, 154 audio features originally used by ellis and lee (2004) to describe audio segments are computed. for each fifteen-second video segment, the visual feature vector extracted from the sample image and the audio feature vector extracted from the corresponding audio segment are combined into a single feature vector. in the information retrieval stage, the user submits a video clip query at first, then its feature vector is computed and compared with that of video clips in the database, and the most similar clips are retrieved (wang et al. 2006). similar projects in this area include carnegie mellon university’s informedia digital video library (www. informedia.cs.cmu.edu) and muvis of finland’s tampere university of technology (http://muvis.cs.tut.fi/index. html). content-based information retrieval for other digital formats with the advance of digitization technology, the content and formats of digital libraries are much richer than before. they are not limited to text, image, audio, and video. some new formats of digital content are emerging. digital libraries of 3-d objects are good examples. since 3-d models have arbitrary topologies and cannot be easily “parameterized” using a standard template as in the case for 2-d forms (bustos et al. 2005), contentbased 3-d model retrieval is a more challenging research topic than other multimedia formats discussed earlier. so far, four types of solutions—primitive-based, statistics-based, geometry-based, and view-based—have been found (bimbo and pala 2006). primitive-based solutions represent 3-d objects with a basic set of parameterized primitive elements. parameters are used to control the shape of each primitive element and to fit each primitive element with a part of the model. with statistics-based approaches, shape descriptions based on statistical modfigure 5.1. the user composes a query figure 5.2. search results for the sample query 46 information technology and libraries | march 200846 information technology and libraries | march 2008 els are created and measured. geometry-based methods, however, use geometric properties of the 3-d object and their measures as global shape descriptors. for viewbased solutions, a set of 2-d views of the model and descriptors of their content are used to represent the 3-d object shape (bimbo and pala 2006). another novel example is moustakas et al.’s (2005) project on 3-d model search using sketches. in the experimental system, the vector of geometrical descriptors for each 3-d model is calculated during the feature extraction stage. in the retrieval stage, a user can initially use one of the sketching interfaces (such as the virtual reality interface or by using an air mouse) to sketch a 2-d contour of the desired 3-d object. the 2-d shape is recognized by the system, and a sample primitive is automatically inserted in the scene. next, the user defines other elements that cannot be described by the 2-d contour, such as the height of the object, and manipulates the 2-d contour until it reaches its target position. the final query is formed after all the primitives are inserted. finally, the system computes the similarities between the query model and each 3-d model in the database, and renders the best matching records. an online demonstration can be found for a european project specifically designed for a 3-d digital museum collection, sculpteur (www.sculpteurweb.org). from its web-based search interface, a user can choose to do a metadata search or content-based search for a 3-d object. the search strategy here is somewhat similar to that in some cbir systems: the user can upload a 3-d model in vrml formats, then select a search algorithm (such as similar color, texture, etc.) to perform a search within a digital collection of 3-d models. as 3-d computer visualization has been widely used in a variety of areas, there are more research projects focusing on the content-based information retrieval techniques for this new multimedia format. ■ conclusion there is no doubt that content-based information retrieval technology is an emerging trend for digital library development and will be an important complement to the traditional text-based retrieval technology. the ideal cbir system can semantically understand the information in a digital library, and render users the most desirable data. however, the machine understanding of semantic information still remains to be a great difficulty. therefore, most current research projects, including those discussed in this paper, deal with the understanding and retrieval of lower-level features or physical features of multimedia content. certainly, as related disciplines such as computer vision and artificial intelligence keep developing, more researches will be done on higher-level feature-based retrieval. in addition, the growing varieties of multimedia content in digital libraries have also brought many new challenges. for instance, 3-d models now become important components of many digital libraries and museums. content-based retrieval technology can be a good direction for this type of content, since the shapes of these 3-d objects are often found more effectively if the user can compose the query visually. new cbir approaches need to be developed for these novel formats. furthermore, most cbir projects today tend to be web-based. by contrast, many project were based on client applications in the 1990s. these web-based cbir tools will have significant influence on digital libraries or repositories, as most of them are also web-based. particularly in the age of web 2.0, some large digital repositories—such as flickr for images and youtube and google video for video—are changing people’s daily lives. the implementation of cbir will be a great benefit to millions of users. since the nature of cbir is to provide better search aids to end users, it is extremely important to focus on the actual user’s needs and how well the user can use these new search tools. it is surprising to find that little usability testing has been done for most cbir projects. such testing should be incorporated into future cbir research before it is widely adopted. bibliography bimbo, a.

revitalizing an integrated library system yan han and atifa rawan this paper describes an afghanistan digital library initiative of building an integrated library system (ils) for afghanistan universities and colleges based on open-source software. as one of the goals of the afghan equality digital libraries alliance, the authors applied systems analysis approach, evaluated different open-source ilss, and customized the selected software to accommodate users’ needs. improvements include arabic and persian language support, user interface changes, call number label printing, and isbn-13 support. to our knowledge, this ils is the first at a large academic library running on open-source software. the last quarter­century has been devastating for afghanistan, with an uninterrupted period of inva­ sions, civil wars, and oppressive regimes. “since 1979, the education system was virtually destroyed on all levels. schools and colleges were closed, looted, or physically reduced; student bodies and faculties were emptied by war, migration, and eco­ nomic hardship; and libraries were gutted.”1 kabul university (ku), for example, was largely demolished by 1994 and completely closed down in 1998. it is universally recognized that afghanistan desperately needs trained faculty, teachers, librarians, and staff. the current state of the higher education system is one of dramatic destruction and deteriora­ tion. based on rawan’s assessments of ku library, most of its collections were damaged or destroyed. she found that there were approximately 60,000 to 70,000 books in english, 2,000 to 3,000 books in persian, and 2,000 theses in persian. none of these collections have manual or online catalog records. the library has eigh­ teen staff members, but not all are fully trained in library activities.2 rebuilding the educational infra­ structure in afghanistan is essential. afghan equality digital libraries alliance the university of arizona (ua) library has been involved in rebuilding academic libraries in afghanistan since april 2002. in 2005, we were invited to be part of the digital libraries alliance (dla) as part of the afghan equality alliances: 21st century universities for afghanistan initiative funded by the usaid and washington state university. dla’s goal is to build the capacity of afghan libraries and librarians to work with open source digital libraries platforms; and to provide and enhance access to schol­ arly information resources and open content that all afghanistan univer­ sities can share. revitalizing the afghan ils an integrated library system (ils) usually includes several critical com­ ponents, such as acquisitions, cat­ aloging, catalog (search and find), circulation, and patron management. traditionally it has been the center of any library. recent developments in digital libraries have resulted in dis­ tributed systems in libraries, and the ils is treated as one of many digital library systems. it still is critical to have a centralized ils to provide a primary way to access library­owned materials for afghanistan universi­ ties and colleges. other services, such as interlibrary loan and other digital library systems, can be further devel­ oped to extend libraries’ services to users and communities. the ua library is working collab­ oratively with other dla members, including universities around the world and universities in afghanistan. one of the goals is to develop a digital library environment, includ­ ing a centralized ils for four aca­ demic universities in kabul (kabul university, polytechnic university, kabul medical university, and kabul education university). in the future, the ils will include other regional institutions throughout afghanistan. the ils will support 30,000 students and 2,000 faculty in afghan universi­ ties and colleges. overview of the ils market currently the ils market is primar­ ily dominated by commercial sys­ tems, such as innovative interface, endeavor, and sirsi. compared with other computing areas, open­source systems in ils are immature and limited, as there are only a few prod­ ucts available, and most of them do not have the full features of an ils. however, they are providing a valu­ able alternative to those costly com­ mercial systems. based on the availability of exist­ ing funding, experiences with com­ mercial vendors, and consideration of vendor supports and future direc­ tions, the authors decided to build a digital library infrastructure with the open concept (open access, open source, and open standards). the decision is widely influenced by glo­ balization, open access, open source, open standards, and increasing user expectations. at the same time, the decision gives us an opportunity to develop and integrate new tools and services for libraries as suggested by the university of california.3 koha is probably the most renowned open­source ils. it is yan han (hany@u.library.arizona.edu) is systems librarian and atifa rawan (rawana@u.library.arizona.edu) is librarian at the university of arizona libraries, tucson. afghanistan digital library initiative | han and rawan 45 a full­featured ils, developed in new zealand and first deployed in horowhenua library trust in 2000. so far koha has been running in a few public and special libraries. the underlying architecture is the linux, apache, mysql, and perl (lamp) stack. building on a simi­ lar lamp (linux, apache, mysql, and php) architecture, openbiblio has a relatively short history, releas­ ing its first beta 0.1.0 version in 2002 and currently in beta 0.5.1 version. webils is an open­source ils based on unesco’s cds/isis database, developed by the institute for computer and information engineering in poland. the software has some ils features, including cataloging, catalog (search and find), loan, and report modules. weblis must run on windows and window­ based web servers, such as xitami/ microsoft iis and isis database. gnuteca, another open­source ils widely deployed in south america universities, was developed in brazil. as with webils, it has some ils features, such as cataloging, cata­ log, and loan; however, the software interface is written in portuguese, which presents a language barrier for u.s. and afghanistan users. the paper open source integrated library systems provides a good overview of other systems.4 systems analysis the authors adopted systems analy­ sis by taking account of afghan col­ lections, users’ needs, and systems functionality required to perform essential library operations. koha was chosen as the base software, due to its functionality, maturity, and support. some of the reasons are: ■ the software architecture is open­ source lamp, which is popular, stable, and predominant. ■ our staff have skills in these open software systems. ■ it is a full­featured open­source ils. certain components, such as multiple branch support and user management, are critical. ■ two large public libraries serv­ ing population of 30,000 users in new zealand and united states have been running their ils on koha for a few years. the soft­ ware is stable, and most bugs have been fixed. ■ koha has a mailing list that is used by koha developers and users as a communication tool to ask and answer questions. kabul universities have com­ puter science faculty and students who have the capacity to participate in the development. due to working schedules and locations, we prefer to develop and maintain the system in the ua library. the technical project team consists of three people: yan han, who is responsible for manag­ ing the overall implementation and development in the open source ils system; one part­time (twenty hours per week) student developer whose major task is to develop and man­ age source code; and a temporary student (ten hours per week for two months) responsible for translating english to farsi and dari. testing tasks, such as unit testing and sys­ tem testing, are shared by all mem­ bers of the team. major challenges farsi and dari languages support koha version 2.2 cannot correctly handle east asian language records, including farsi and dari records. supporting persian, farsi, and dari records is a very important require­ ment, as these afghan universities have quite a few persian and dari materials. koha generates a web­ based graphical user interface (gui) through perl included templates that use a html meta tag with western character set (iso­8559­1) to encode characters. browsers such as internet explorer and firefox use the meta tag to decode characters with a predefined character set. therefore, other characters, such as arabic and persian as well as chinese would not be displayed correctly. the perl tem­ plates were identified and modified to allow characters to be encoded in unicode, and this solved the prob­ lem. persian and dari characters can be entered into the cataloging module and displayed correctly in the gui. however, we should understand the limitations of this approach when dealing with other east asian character sets, such as chinese characters. only frequently used characters can be represented. a project of academia sinica is one of the efforts to deal with 65,000 unique chinese characters.5 farsi/dari gui as the project is designed for local afghanistan users, there is a need for a farsi and dari gui. the current version of koha does not have such an interface, and we decided to create a new farsi/dari gui for the opac. the koha system’s internal structure is logically arranged; therefore, our development work in translation is not difficult to manage. the transla­ tion student translates english words in perl template files into farsi and dari. at the same time he works with the developer to make sure it is dis­ played correctly in the opac. figure 1 is the screenshot of the gui. other improvements we further developed a spine label printing module and integrated the module into the ils, as there is no such function provided. the module allows library staff to print one or more standardized labels (1.5 inches high by 1 inch wide) with oclc formats on gaylord lsl 01 paper, which has fifty­six labels per sheet. 46 information technology and libraries | december 2007 lstaff can select an appropriate label slot to start and print out his or her choices of labels through the web preview feature. this feature eases library staff operations and provides cost savings for label papers. isbn­13 replaced isbn­10 after january 1, 2007, and any ils has to be able to handle the new isbn­13. our ils has been improved to han­ dle both isbn standards. thanks to koha’s delegation of the gui and major functionality, interfaces such as fonts and web pages can be modi­ fied through the templates and css. a z39.50 service has been configured to allow users to search other librar­ ies’ catalogs. hardware and software support afghanistan is still developing its fun­ damental infrastructure: electricity, transportation, and communication. when considering buying hardware for the ils, difficult issues, such as server services and computer parts, have to be solved. even international it companies, such as dell, hp, and ibm, have very limited services and support in afghanistan. regarding software and system support, our strategies are to: ■ maintain and develop the open source software at the ua library by the project team; ■ run one server in kabul, afghanistan, administrated by a local system administrator. ■ run one server in the ua library administrated by the library’s system administrator. cost we estimated our overall cost for building the open­source system is low and reasonable. the system is currently run­ ning on a dell 2800 server ($5,000 for 3ghz cpu, 4gb ram, and five 73gb hard drives), kernel built debian linux (free), apache 2 (free), mysql (free), and perl (free). han spends four hours per week for coor­ dination, communication, and man­ agement of the project. the student developer works twenty hours per week for development and mainte­ nance, while the translation student will spend one hundred hours for translation. conclusion revitalizing an afghan ils is the first important goal to build digital library initiatives for the afghanistan higher education system. by under­ standing afghan university librar­ ies, collections, and users, the ua library is working with other dla members to build the open source ils. the new farsi and dari user interface, language support, and other improvements have been made to meet needs of afghan uni­ versities and colleges. the cost of using and developing existing open source software is reasonable. acknowledgments we thank usaid,

canada. less has been reported, however, about the costs of textbooks outside of north america, including in europe. we address this gap in the knowledge through a case study of one irish higher education institution, focusing on the cost, accessibility, and licensing of textbooks. we report here on an investigation of textbook prices drawing from an official college course catalog containing several thousand books. we detail how we sought to determine metadata of these books including: the formats they are available in, whether they are in the public domain, and the retail prices. we explain how we used methods to automatically determine textbook costs using google books api and make our code and dataset publicly available. introduction the cost of textbooks is a hot topic for higher education. it has been reported that by 2014 the average student spent $1,200 annually on textbooks.1 another study claimed that between 2006 and 2016 the costs of college textbooks increased over four times the cost of inflation.2 despite this rise in textbook costs, a survey of more than 3,000 us faculty members (“the babson survey”) found that almost every course (98 percent) mandated a textbook or related study resources.3 one response to the challenge of rising textbook costs is open textbooks. open textbooks are a type of open educational resource (oer). oers have been defined as “teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and repurposing by others. open educational resources include full courses, course materials, modules, textbooks, streaming videos, tests, software, and any other tools, materials, or techniques used to support access to knowledge.”4 oers stem from the principle that access to education is a human right and that, as such, education should be accessible to all.5 hence an open textbook is made available under terms which grant legal rights to the public, not only to use, but also to adapt and redistribute. creative commons licensing is the most prevalent and well-developed intellectual property licensing tool for this purpose. open textbook projects aimed at promoting publishing and redistributing open textbooks, both in digital and print formats, have been growing. for example, the bcampus project in canada began in 2012 with the aim of creating a collection of open textbooks aligned with the most popular subject areas in british columbia.6 the project has shown strong growth, with over 230 open digital textbooks now available and more than forty institutions involved. a significant recent determining textbook cost, formats, and licensing | costello, bolger, soverino, and brown 92 https://doi.org/10.6017/ital.v38i1.10738 development in open textbooks occurred in march 2018, when the us congress announced a $5 million investment in an open textbook initiative.7 in addition to helping change institutional culture, and challenge attitudes to traditional publishing models, one of the most oft-cited benefits of open textbooks is cost savings. according to the college board’s survey of colleges, the average annual cost to us undergraduate students in 2017 for textbooks and materials was estimated at $1,250.8 this figure is remarkably close to the aforementioned figure of $1,200 a year, as reported by baglione and sullivan. however, there is little known about the monetary face value of books that students are expected to buy, beyond studies based on self-reported data. students themselves in the us have attempted to at least open the debate in this area by highlighting book price disparities.9 nonetheless, they only report on a very small number of books, and the college board representing on-campus us textbook retailers have disputed their results for this reason, claiming that they have been selective in the book prices they have chosen. hence this study seeks to address the gap that exists in knowledge about the true cost of textbooks in higher education. this is in the context of a wider research project we are conducting on open textbooks in ireland.10 determining the cost of books is not straightforward as books can be new, used, rental, or digital subscription. however, the cost of new books does set a baseline for other forms, particularly rental and used books. our aim here is hence to start with new books, by analyzing costs of all the required and recommended textbooks of one higher education institution (hei) in ireland. the overarching research question this study sought to address is: what is known about the currently assigned textbooks in an irish university? the sub-questions were: • rq1: what is the extent of textbooks that are required reading? • rq2: what are the retail costs of textbooks? • rq3: are textbooks available in digital or e-book form? • rq4: are textbooks available in the public domain? the next section outlines our methodology and how we sought to find answers to these questions. methods in this section we describe our approach, the dataset generated, and the methods we used to analyze the data. we identified a suitable data source comprising the official course catalog of a hei in ireland with more than ten thousand students. in the course catalog faculty give required and recommended textbook details for all courses. this information is freely accessible on the website of the hei; the course catalog is powered by a software system known as akari (http://www.akarisoftware.com/). akari is a proprietary software system used by several heis in and outside ireland to create and manage academic course catalogs. the course team gained access to a download of all books recorded in the database of the course catalog (figure 1). in this catalog, fields are provided for lecturers to input information for students about books such as title, international standard book number (isbn), author, and publisher. following manual and automated data cleansing, 3,014 unique records of books were created. due to the large number of books, at this stage we sought a programmatic solution for finding out more information about these books. information technology and libraries | march 2019 93 figure 1. course catalog screenshot. we initially thought that isbns might prove the best way to accurately reconcile records of books. however, many isbns were incomplete or mistyped. moreover, many instructors simply did not enter an isbn. given the capacity for errors in the data—for instance, some lectures simply entered “i will tell you in class” in the book title field—we required a tool that could handle fuzzy search queries, e.g. cases where a book title or author were misspelled. the tool we selected was the google books application programming interface (api).11 this api provides an interface to the google books database of circa thirty million books. the service, like the main google search engine, is forgiving of queries that are mistyped or misspelled. hence, we constructed a query based on a combination of author name, book title, and publisher. following experimentation, we determined that these three search terms together allowed us to find books with a high degree of accuracy whilst also accounting for possible spelling errors. determining textbook cost, formats, and licensing | costello, bolger, soverino, and brown 94 https://doi.org/10.6017/ital.v38i1.10738 figure 2. system design. we then wrote a custom javascript middleware program deployed in the google cloud platform. this program parsed the file of the book search queries, passed them to the google books api as search requests and saved the results. the api returned results in javascript object notation (json) format. json is a modern web language for describing data. it is related to javascript and can be used to translate objects in the javascript programming language into textual strings. it is used as a replacement for xml as it is arguably more human readable and is considerably less verbose. we then imported this json into a mongodb database to filter and clean the data, before finally exporting them to excel for statistical analysis. mongodb is a document store database that natively stores objects in the json format and allows for efficient querying of the data. the google books api provides some key metadata on books aside from the usual author, publisher, isbn, edition, pages, etc. as it gives prices for selected books. google draws this information from its own e-book store which contains over three million books and a network of resellers who sell print and digital versions of the books. in addition to price, google books also contains information on accessible versions of books, digital/e-pub versions, pdf versions, and whether the book is in the public domain. we have published a release of this dataset and all of our code to the software repository github. we then used the zenodo platform to generate a digital object identifier (doi) for the code.12 one of the functions of the zenodo platform is to allow for code to be properly cited and referenced. we published our code in this way for others interested in replicating this work in other contexts. in the next section we will provide an analysis of the results of our queries. results after extracting and processing the data from the course catalog and google platforms, we obtained 3,030 unique course names and in these courses we found over 15,414 books listed. required versus recommended reading from the course catalog data, we found that 11,022 (71.5 percent) books were required readings and the remaining 4,392 (28.5 percent) were recommended. information technology and libraries | march 2019 95 upon cleaning and removing duplicates and missing data, we identified 3,014 books that could be queried using the google books api. querying the api returned results for 2,940 books, i.e. it found 97 percent of the books and only seventy-four books could not be found. the google books api returns information in json format. figure 3 below shows an example of the json information returned for one book. { "volumeinfo" : { "title" : "psychiatric and mental health nursing", "authors" : [ "phil barker" ],

as follows: figure 4. availability of 2,940 books in digital formats and public domain license. as per figure 4, only 0.18 percent (six) of the books had a version available in the public domain according to google books. cost results the google books api only returned prices for 596 (20 percent) of the books that we searched for. within that sample, the cost ranged from $0.99 to over $452, as illustrated in figure 5. the median price of a book was $40, and the mean price was $56.67. as there are on average 3.96 books per course, this implies an average cost to students of $224.41 per course taken. as students take an average of 8.05 courses per year, this further implies a cost per year of $1,806.50 per student if they were to buy new versions of all the books. 1,219 (39.73% )

and conclusion we have demonstrated that it is possible to programmatically search and determine the prices of large numbers of books. we used this information to attempt to estimate the full economic cost of books to students on average in an irish hei. we are still actively developing this tool and encourage others to use and even contribute to the code which we have published with the dataset. this proof of concept tool may allow stakeholders with an interest in book costs for students to quickly get real data on large numbers of books. ultimately, we hope that this will help highlight the costs of many textbooks. our findings also highlight relatively low levels of digital book availability. very few books were found to be in the public domain. a limitation of this research is that there are issues around the coverage of google books and its index policies or algorithms. in a literature review of research articles about google books in 2017, fagan pointed out that the coverage of google books is “hit and miss.”13 in 2017, google books included about thirty million books, though google did not release specific details on its database, as emphasized by fagan. it is known that content includes digitized collections from over forty libraries, and that us and englishlanguage books are overrepresented.14 furthermore, google books is only returning results for books that are in the public domain and cannot tell us if books are made available through open licenses such as creative commons. accepting such caveats, however, we have found the google books api to be a very useful tool for answering questions about large numbers of books in a systematic way and hope that our findings can help others. the prices that we derived in this study were for new books only. however, the new book prices provide a baseline for all other prices, e.g. a used book or a loan book price will be relative to a new book price and library budgets will need to take account of new book prices.15

libraries | march 2007 author id box for 2 column layout opac design enhancements and their effects on circulation and resource sharing within the library consortium environment michael j. bennett a longitudinal study of three discrete online public access catalog (opac) design enhancements examined the possible effects such changes may have on circulation and resource sharing within the automated library consortium environment. statistical comparisons were made of both circulation and interlibrary loan (ill) figures from the year before enhancement to the year after implementation. data from sixteen libraries covering a seven-year period were studied in order to determine the degree to which patrons may or may not utilize increasingly broader opac ill options over time. results indicated that while ill totals increased significantly after each opac enhancement, such gains did not result in significant corresponding changes in total circulation. m ost previous studies of online public access catalog (opac) use and design have centered on transaction­log analysis and user survey results in the academic library environment. measures of patron success or lack thereof have traditionally been expressed in the form of such concepts as “zero­hit” analysis or the “branching” analysis of kantor and, later, ciliberti.1 missing from the majority of the literature on opac study, however, are the effects that use and design have had on public library patron borrowing practices. major drawbacks to transaction­log analyses and user surveys as a measure of successful opac use include a lack of standardization and the inherent difficulties in interpreting resulting data. as peters notes, “[s]urveys measure users’ opinions about online catalogs and their perceptions of their successes or failures when using them, while transaction logs simply record the searches conducted by users. surveys,” he concludes, “mea­ sure attitudes, while transaction logs measure a specific form of behavior.”2 in both cases it is difficult, in many instances, to draw clear conclusions from either method. circulation figures, on the other hand, measure a more narrowly defined level of patron success. circulation is a discrete output that is the direct result of patrons’ initiated interaction with one or many library collections, one or many levels of library technology. with the recent advent of such enhanced opac functionality as patron­placed holds on items from broader and broader catalogs, online catalogs now more than ever not only serve as search mechanisms but also as ways for patrons to directly obtain materials from multiple sources. it follows that an investigation of the possible effects such enhancements may have on general circulation trends is warranted. ■ literature review during the mid­to­late 1980s, transaction­log analysis was introduced as an inexpensive and easy method of looking at opac use in primarily the academic library environment. peters’s transaction­log survey of more than thirteen thousand searches executed over a five­ month period at the university of missouri­kansas city remains particularly instructive today for its large sample and transferable design as well as its interpreta­ tion of results.3 here analysis was broken into two phases. in phase one, usage patterns by search type and failure rates as measured by zero hits were examined as dependent vari­ ables with search type as the independent variable in a comparison study. phase two took this one step further in the assigning of what peters termed “probable cause” of zero hits. these probable causes fell into patterns that, in turn, resulted in the identification of fourteen discernable error types that included such things as typographical errors and searches for items not in the catalog. once again, search type formed the independent variable while error type shaped the dependent variable in a simple study of error types as a percentage of total searches. peters found that users rarely employed truncation or any advanced feature searches and that failures were due primarily to such consistent erroneous search patterns as typographical errors and misspellings. more importantly, however, he cogently reassessed transaction­log analysis as a tool and critiqued its limitations. zero hits, for exam­ ple, need not necessarily construe failure when a patron performs a quality search and finds that the library simply does not own the title in question. concerning intelligible outputs from transaction­log study, peters found that, “if the user is seen as carrying on a dialog of sorts with the online catalog, then it could be said that most transaction logs record only half of the conversa­ tion. more information about the system’s response to the user’s queries would help us better understand why patrons do what they do.”4 a look at subsequent transaction­log analyses into the 1990s reveals somewhat differing research approaches yet strikingly similar results. wallace (1993) duplicated peters’s methods at eleven terminals within the university of colorado library system.5 her efforts spanned twenty hours of search monitoring and resulted in 4,134 logged searches. these were defined by carl system search type, (e.g., word, subject), then analyzed as cumulative totals and percentages of all searches. in this case, how­ michael j. bennett michael j. bennett (mbennett@cwmars.org) is digital initiatives librarian, c/w mars library network, worcester, massachusetts. article title | author 37opac design enhancements | bennett 37 ever, failed searches (peters’s zero hits) were eliminated entirely from the sample as wallace focused primarily on patterns of completed searches and did not concern her­ self with questions of search success or failure, thus limit­ ing the scope of her findings. among searches analyzed, results were comparable to peters’s.6 in keeping with peters’s line of thinking, wallace remarked, intriguing vagaries in human behavior during an infor­ mation search process continue to stymie researchers’ efforts to understand that process. . . . current, widely used and described guidelines, rules and principles of searching simply do not take into account important aspects of what is really going on when an individual is using a computer to search for information.7 in 1998, ciliberti et al. conducted a materials avail­ ability study of 441 opac searches at adelphi university over a three­week period during fall semester.8 their work combined kantor’s branching­analysis methodol­ ogy with transaction­log analysis of opac use in order to better understand if users obtain the materials they need through the online catalog.9 sampling was accom­ plished during random open hours and drew informa­ tion from undergraduate, graduate, and faculty users. survey forms included questions of what patrons were searching for. forms were then picked randomly by staff for re­creation. the study was unclear as to the actual design of these forms and their queries. as a result their effectiveness remains questionable. a seven­category scheme was developed to code search failures that closely followed kantor’s branching analysis, where the concept of errors extends beyond just opac and its design to include such things as library collection devel­ opment and circulation practices.10 the survey itself along with the loss of accuracy that can be expected from patrons attempting to describe their searches on paper, then having these same searches re­created by research staff lead this author to question the data’s validity. as peters has noted, surveys are good for assessing opac users’ opinions but not necessarily their behavior.11 it would seem that in this instance the tool did not fit the task. this study did, however, use transaction logs after the initial survey analysis and indeed found discrepancies between the self­report (survey) and actual transaction­log data. search errors were subsequently categorized as pre­ viously described.12 though branching analysis is adept at examining on a holistic, entire­library scale (e.g., the ques­ tion of why patrons are not able to obtain materials), the method’s inherent breadth of focus does not lend itself to fine scrutiny of opac design issues in and of themselves. further refinement of the transaction­log analysis methodology may be seen in blecic’s et al. four­year longi­ tudinal study of opac use within the university of illinois library system.13 once again, failed searches, termed “zero postings” by the authors, were examined as dependent variables and percentages of the total number of searches and were used as a control. reasons for zero postings (e.g., searches missing search statements, author names entered in incorrect order) fell into seven separate catego­ ries. subsequent transaction­log sets were then culled after three incremental opac enhancements. enhancements included redesigns of general introductory and explain screens. z­test analysis of the level of equality between percentages of zero postings from log set to log set was then made in order to assess whether or not the enhance­ ments had any affect on diminishing said percentages and thus improving searching behavior. what blecic et al. found was temporary improve­ ment in patron searches followed by an unexpected lowering of patron performance over time. confounding attributes to the study include its longitudinal nature in an academic setting where user groups are not constant but variable. sadly, no attempt at tracking such possible changes in user populations was made. also of note was the fact that, as time passed, the command­based opac was increasingly being surrounded by web­based journal database search interfaces that did not require the use of sophisticated search statements and arguments. as users became accustomed to this type of searching, their com­ mand syntax skills may have suffered as a result.14 merits of the study include its straightforward design, logical data analysis, and plausible conclusions. longitudinal studies, though prone to the confound­ ing variables described, nevertheless form a persuasive template for further research into how incremental opac enhancements affect actual opac use over time. variations of transaction­log analysis also include the purely experimental. thomas’s 2001 simulation study of eighty­two first­year undergraduates at the university of pittsburg utilized four separate experimental screen inter­ faces.15 these interfaces included one that mimicked the current catalog with data labels and brief bibliographic displays, a second interface with the same bibliographic display but no data labels, and a third that contained the data labels but modified the brief display to include more subject­oriented fields. a fourth interface viewed the same brief displays as the third group but with the labels removed. users were pretested for basic demographic informa­ tion and randomly assigned to one of the four experi­ mental interface groups. each group was then given the same two search tasks. for the first task, users were asked to select items that they would examine further for a hypothetical research paper on big­band music and the music of duke ellington. the second task involved asking participants to examine twenty bibliographic records and to decide whether they would choose to look into these records further. participants were then asked to identify the data elements used to inform their 38 information technology and libraries | march 200738 information technology and libraries | march 2007 relevance choices. resulting user behavior was subse­ quently tracked through transaction logs. for thomas’s experimental purposes, though, trans­ action logs took on a higher level of sophistication than in earlier comparative studies. here participants’ actions were monitored with a greater level of granularity. quantitative data were tracked for screens visited, time spent viewing them, total number of screens, total number of bibliographic citations examined at each level of speci­ ficity, and total time it took to complete the task. because of the obtrusive nature of the project, a third party was hired to administer the experiment. chi­square analysis of demographic data found no significance among partici­ pant groups in terms of their experience in using comput­ ers, online catalogs, or prior knowledge of the problem topic. this important analysis allowed the researchers a higher level of confidence in their subsequent findings. results in many instances were, however, inconclu­ sive. factors impairing the clarity of conclusions included the number of variables analyzed and the artificiality of the test design itself. thomas comments on one particular example of this: one of the fields that previous researchers said that library users found important was the call number field. obviously, without the call number, locating the actual item on the shelf is greatly complicated. in this experi­ ment, however, participants were not asked to retrieve the items they selected; thus, their perceived need for the call number may well have been mitigated.16 here is further evidence that a study of opac activity viewed in the context of actual outcomes, namely circula­ tion, is a logical approach to consider. most recently, graham at the university of lethbridge, alberta, examined opac subject searching and no­ hit results and considered two possible experimental enhancement types in order to allow users the ability to conduct more accurate searches.17 over a one­week period, 1,521 no­hit subject searches were first sampled and placed into nine categories by error type. subtotals were then expressed as percentage distributions of the total. a similar examination of 37,987 no­hit findings was also made over the course of four calendar years, form­ ing a longitudinal approach. percent distribution of error types from the two studies were then compared and were found to be similar with “non­library of congress subject headings” being the predominant area of concern. graham then attempted to improve subject searching by systematically enhancing the catalog in two ways. first, cross­references were created based upon the original no­ hit search term and linked to existing library of congress subject headings (lcshs) that graham interpreted as appropriate to the searcher’s original intentions. second, in instances where the original search could not be easily linked to an existing lcsh, a pathfinder record was cre­ ated that suggested alternate search strategies. all total, 10,520 new authority records and 2,312 pathfinder records were created over the course of the longitudinal study.18 the experiment, unfortunately, only went this far. no attempt was subsequently made to test whether these two methods of adding value to an existing opac search interface made a difference in users’ experiences. though creative in its suggested ameliorations to no­hit searches, the study also lacked any statistical testing of comparative data among sample years. possible problematic design issues, such as the relative complexity of pathfinders and how this might affect their end use were discussed but never tested through the analysis of real outcomes. in summary, major weaknesses of the transaction­log analysis model as demonstrated through the literature include: 1. lack of standardization among general study methodologies. 2. lack of standardization of opacs themselves: command structure and screen layout differ among software vendors. 3. lack of standards on measurable levels of search “success” or “failure.” while the following study of opac design enhance­ ments in the public library consortium environment did not directly address the first two points of emphasis, it was this author’s expectation that the lack of stan­ dardized notions of opac search success or failure found throughout the literature may be better addressed through a longitudinal analysis of discrete circulation and ill statistics. in this way, these quantifiable outcomes, both the direct results of patron initiation, would better assume clearer measures of patron success or failure in opac end use. ■ purpose and methodology in recent years, both academic and public libraries have invested substantial capital in improving opac design and automated systems. to what extent have these improvements affected the use of library materials by public library patrons? in order to better examine the question, this study tracked, over a seven­year period dating back from july 1998 through june 2005, the circulation and systemwide holds statistical trends of sixteen member libraries of c/ w mars, a massachusetts automated library network of 140 libraries. during this time a number of discrete, incre­ mental opac modifications granted patrons the ability to accomplish tasks remotely through the opac that previ­ ously had required library staff mediation. among these article title | author 3�opac design enhancements | bennett 3� changes, the initiation of intra­consortium (c/w mars) patron­placed holds, and the subsequent introduction of a link from the existing opac to the massachusetts virtual catalog (nine massachusetts consortiums, four university of massachusetts system libraries) were examined. this author hypothesized that such opac enhance­ ments that allow for broader choices of patron­placed holds would result in increases in both total circulation and total network transfers (ill) of library materials one year after initial enhancement adoption. as both total cir­ culation and total ill grew, it was hypothesized that ill as a percent of total circulation would likewise increase due to the fact that each opac enhancement was targeted directly toward facets of ill procurement. opac enhancements followed the schedule below: 1. general c/w mars network systemwide holds (requests mediated through library staff only), november 2000 2. patron­placed holds (request button placed on c/ w mars opac screens), december 2002 3. c/w mars participation in the massachusetts virtual catalog (additional button for pass through opac searches and requests from c/w mars catalog into the massachusetts virtual catalog), august 2004 these dates served as independent variables in a study of separate dependent variables (total circulation and total ills received) for all eight libraries one year after initial adoption of a new enhancement. for the sake of continu­ ity the terms holds and ills were used interchangeably throughout this examination. t­test comparisons to fig­ ures from the year prior to enhancement were then made for statistical significance. in addition, ills received as a percentage of total circulation (dependent variable) for all fifteen libraries one year after initial adoption of a new enhancement were also calculated and compared to the year prior to enhancement through z­test analysis. libraries chosen were a random sample from both central and western geographic regions of the network. sampled institutions did not go through any substantial renovations, drastic open hours changes, or closures dur­ ing the study period in order to better avoid potential con­ founding variables that may have skewed the resulting data. raw circulation and ill figures were taken directly from the massachusetts board of library commissioners’ (mblc) data files for fiscal years 1999 through 2004.19 in the mblc’s data files, the following fields, sorted by library, correlated to this study’s statistical reporting: “dircirc” = “circulation” “loan from” = “ill” as fiscal year (fy) 2005 figures for circulation and ill had not yet been compiled by mblc at the time of this writing, these statistics were in turn taken directly from reports run off of c/w mars’s network servers. it should be noted that similar c/w mars reports are distributed and used by the consortium’s libraries them­ selves each fiscal year for reporting circulation and ill statistics to mblc. raw data by library were entered into microsoft excel spreadsheets. totals for circulation and ills received for all libraries by fy of opac enhancement were totaled and then compared to fy data prior to enhancement as a percent change value. excel’s data analysis tools were then employed to run t­tests (paired two sample for means) in tables 1 through 5 to analyze the level of change for significance from one sample to the next in both total circulation and total ills. (all tables and charts can be found in appendix following article.) tests for sig­ nificance employed two­tailed t­tests with an alpha level set to .05. raw data for these same libraries across identical study years were also entered into subsequent spread­ sheets (tables 6 through 10) for additional z­tests (two samples for means) to analyze the level of change for significance from one fy sample to the next in ills received as a percentage of total circulation. here tests for significance employed two­tailed z­tests with an alpha level set to .05. ■ results and discussion the results of a sixteen­library, seven­year longitudinal study of total circulation and total ills­received statistics are outlined in tables 1 through 5, charts 1 through 10. in addition, an analysis of ills received as a percentage of total circulation during this same time period among sampled libraries is represented in tables 6 through 10. over the course of the study a total of 22,277,245 circula­ tion and 624,286 ill transactions were examined from july 1998 through june 2005. yearly comparisons in total circulation and total ills received from fy ’99 to fy ’00 were made to analyze the level of changes in circulation and ill statistics between years before any opac ill enhancements were under­ taken. as such these numbers gave insight into what changes, if any, normally occur in circulation and ill fig­ ures prior to a schedule of substantial opac ill enhance­ ments. although the year­to­year comparisons over the course of subsequent enhancement rollouts were made to test for the statistical significance of the year prior and following a particular functionality addition, the ’99 to ’00 40 information technology and libraries | march 200740 information technology and libraries | march 2007 comparison was made to form a control of what circula­ tion and ill trends may look like between years of no drastic workflow or design changes. results showed that this yearly comparison prior to the beginning of opac enhancements (table 1, charts 1 and 2) showed no significant change from one year to the next in total circulation (t = 1.81, p > 0.05) or total ills received (t = ­0.76, p > 0.05). circulation from ’99 to ’00 declined slightly by 3.42 percent while total ills received increased 3.35 percent. the mblc’s available retrospec­ tive data set currently only goes back to fy ’99, so a deeper understanding beyond this two­year comparison of normal year­to­year trends was impossible to achieve. yet data from this sample suggest that both circulation and ills may trend statistically flat from one year of little if any alteration of ill design to the next. additionally, comparisons of the percent of total ills received to total circulation were made between ’99 and ’00 (as will be seen in table 6) and were found to be insignificantly different (z = ­0.23, p > 0.05). ills received made up 0.61 percent of total circulation in fy ’99 and 0.65 percent of total circulation in fy ’00. during fy ’01 (november 2001), c/w mars rolled out automated systemwide holds functionality whereby library staff were first able to place patron requests for materials at other c/w mars member libraries through the consortium’s automated circulation system. up until this point, holds (ills) were placed primarily by staff through e­mail or faxed requests from one ill depart­ ment to another. patrons would request material either verbally with staff or through the submission of a paper or electronic form. staff would then look up the item in the electronic catalog and make the request. with the advent of systemwide holds, staff still accepted requests in a similar fashion, but instead of using the fax or e­mail, they began to place requests directly into the network’s innovative millennium circu­ lation clients. from there, the automated system not only randomly chose the lending library within the system but also automatically queued paging slips at the lending library for material that would subsequently be sent in transit to the borrowing location. by this time in the network’s development, opac had also graduated from a character­based telnet system to a smoother web design. but the catalog, in terms of directly assisting in the placing of ill requests, func­ tioned as it always had—it was still individually a search­ ing mechanism. the introduction of systemwide holds led to the sec­ ond largest jump in ill figures out of all comparative samples (table 2, chart 4). interestingly enough, the con­ siderably significant 127.23­percent gain in ill activity from fy ’00 to fy ’01 (t = ­4.07, p < 0.05) did not translate into a significant increase in total circulation. in fact, cir­ culation declined during this period, not significantly (t = 1.87, p > 0.05), but by 2.40 percent nonetheless (table 2, chart 5). a comparison of the percent of ills to total circulation from fy ’00 to fy ’01 (table 7) indicated a sig­ nificant increase of 0.65 percent to 1.52 percent (z = ­4.20, p < 0.05). more on the possible effects to circulation that rising levels of ills may elicit will be touched upon. though no statistical evaluations were made between fy ’01 and fy ’02 (as no novel ill changes were made over this period), it should be noted that during fy ’02 the network first allowed patrons the ability, through opac, to log into their own accounts remotely. patrons were given the ability to set up a personal identification number and view such things as a list of their checked­ out items. patrons were also allowed to place checks next to such items and to renew these items remotely. fy ’03 saw the original direct ill enhancement to opac. during this year patrons were first given the opportunity to directly place ill requests of their own (patron­placed holds) for material found in the catalog through the addition of an opac screen request button. up until this time, all material requests had been medi­ ated by library staff. comparative total circulation results from the year before enhancement to fy ’03 (table 3, chart 5) showed only a slightly significant 4.18 percent increase (t = ­2.94, p < 0.05). ills­received figures (table 3, chart 6), however, jumped by a considerable 25.58 percent margin (t = ­4.66, p < 0.05), strongly suggesting that the opac request­ button addition and its facilitation of patron­placed holds had a positive effect upon total ill activity as was hypothesized. finally, total ills received as a percentage of total circulation increased slightly from fy ’02 (2.52 percent) to fy ’03 (3.04 percent) (table 8) but did not rep­ resent a significant shift (z = ­1.51, p > 0.05). the last augmentation to the network’s opac design that this study examined was an additional link for ills through the massachusetts virtual catalog. the massachusetts virtual catalog at the time of this study was an online union catalog of nine massachusetts net­ work consortia and four university of massachusetts system libraries. unlike the previous request­button enhancement that allowed for seamless patron­placed holds within the c/ w mars catalog, the massachusetts virtual catalog link was not a button but a descriptive hyperlink (can’t find the title you want here? try the massachusetts virtual catalog next!) from the network’s opac to the virtual catalog’s own dedicated opac interface. once there, patrons were required to login to the virtual catalog and re­create their search queries from scratch as previous searches were not automatically passed through to the second catalog. in essence, the virtual catalog acted as an additional step for patrons to take beyond c/w mars’s list of holdings to broaden their search for materials that the network’s member libraries did not own. article title | author 41opac design enhancements | bennett 41 comparative figures for total circulation between fy ’04 and fy ’05 (table 4, chart 7) when the virtual catalog link was added to the c/w mars opac screen found circulation down an insignificant 2.04 percent (t = 0.97, p > 0.05), which ran counter to hypothesized expectations. total ills received between fy ’04 and fy ’05 (table 4, chart 8), however, rose 30.85 percent, which proved to be a highly significant increase (t = ­7.03, p < 0.05). additionally ills as a percent of total circulation rose from 4.70 percent in fy ’04 to 6.27 percent in fy ’05 (table 9), which was sta­ tistically significant (z = ­3.28, p < 0.05) and pointed to not only gains in ill itself after the introduction of the virtual catalog link but also to the ever increasing proportion of total circulation that ill activity accounted for. the final statistical comparison accomplished in this study was a look at what possible cumulative effect, if any, both opac enhancements may have had from the year before the first enhancement’s rollout (patron­placed holds request button) to one year after the latest addition (virtual catalog hyperlink from opac). in turn, com­ parative numbers for circulation and ills between fy ’02 and fy ’05 were examined. total circulation over this time (table 5, chart 9) increased insignificantly by 3.46 percent (t = ­1.47, p > 0.05). total ills received (table 5, chart 10), how­ ever, increased by 157.47 percent, the highest significant increase of any two comparative samples (t = ­7.20, p < 0.05). ills as a percent of total circulation also increased significantly from 2.52 percent in fy ’02 to 6.27 percent in fy ’05 (z = ­7.71, p < 0.05) (table 10). if one steps back and examines the various compari­ sons discussed up to this point, certain trends become evident. over the course of the seven­year study, total circulation remained relatively flat, oscillating slightly back and forth, year to year with only one significant increase that occurred after the introduction of patron­ placed holds in fy ’03. these results, excluding fy ’03, ran against hypothesized expectations that predicted that as ill enhancements were rolled out, correspondingly significant increases in circulation would result. total ills received (the fy ’99 to fy ’00 control com­ parison) before the advent of first, network systemwide holds, then a succession of opac design enhancements that allowed for a broader range of patron­initiated ills suggested that these totals run statistically flat from one year to the next. with the advent of systemwide holds, the ill picture, however, began to change dramatically with a significant increase in total ills. this was fol­ lowed by significant increases in ill activity in each study year that came after an opac ill enhancement. these results pointed toward the substantial effect that these enhancements made in total ill activity and sup­ ported hypothesized expectations. when such opac rollouts were examined as a cumu­ lative influence through the prism of ill levels of this past fiscal year (fy ’05) compared to the year before their initial advent (fy ’02), the positive effect that such enrich­ ments had on not only total ill but also on total circula­ tion becomes clearest. for it is through this comparison that it was found that not only did total ills increase significantly but that ills as a percentage of total circula­ tion also increased significantly from the time before the first opac enhancement to the present. total circulation was surprisingly impervious to change and ran statisti­ cally flat during this time. it is clear from this longitudinal study that incremen­ tally granting patrons access to online tools for them to initiate such traditional library business as ills spurs sig­ nificantly large increases in such activity. in other words, these online tools are not ignored but are intellectually and literally grasped. what may be surprising, however, is the degree to which ill has increased as a result of them, to a point where ill has not only taken up a sig­ nificantly greater proportion of total circulation than ever before but also appears to be changing the very nature of circulation itself. future studies may include a deeper examination of the circulation and ill statistical picture farther back in time than this investigation covers to better clarify trends leading up to such major enhancement rollouts. also, similar longitudinal studies from different consortia envi­ ronments may shed further light on evidence discussed throughout this writing. consortia are uniquely poised to offer large statistical sample sizes and standardized workflows within their network­wide ill and circulation software packages and automated statistical programs. this, in turn, results in high­quality, consistent data samples from heterogeneous library sources that are rela­ tively uncorrupted by scattershot recording methods and differing circulation and ill methodologies. finally, a future look at the effects that similar opac ill enhancements may have on borrowing trends beyond general raw transactional figures is warranted. chris anderson, for example, has recently commented on long tail statistical analysis and its relation to library catalogs. here outwardly shifting demand curves for library mate­ rials are hypothesized as collections become more visible and interconnected through the web.20 in a similar vein, a more granular examination of such concepts as possible circulation and ill­activity trends in terms of discrete material types borrowed, patron types who borrow, or a cross­tabulation of these data points would appear to be a fertile next step toward a greater knowledge of ills and circulation as a whole. references 1. t. peters, “when smart people fail: an analysis of the transaction log of an online public access

(pm13@illinois.edu) is reference services & instruction librarian, university of illinois library. abstract this article presents the results of a pilot project that tested the application of algorithmic topic modeling to chat reference conversations. the outcomes for this project included determining if this method could be used to identify the most common chat topics in a semester and whether these topics could inform library services beyond chat reference training. after reviewing the literature, four topic modeling algorithms were successfully implemented using python code: (1) lda, (2) phrase-lda, (3) dmm, and (4) nmf. analysis of the top ten topics from each algorithm indicated that lda, phraselda, and nmf show the most promise for future analysis on larger sets of data (from three or more semesters) and for examining different facets of the data (fall versus spring semester, different time of day, just the patron side of the conversation). introduction the library at the university of illinois at urbana-champaign has included chat reference services since the spring of 2001.1 today, this service is extensively used by library patrons, resulting in thousands of conversations each semester. while in-person reference edges out chat for the largest number of interactions at the main library information desk over the most recent four years, chat questions have a higher number of more complex questions that incorporate teaching or strategizing.2 since the initial implementation of chat, the library has continually assessed and improved chat reference by evaluating the software, measuring the effectiveness and value of the service, and providing staff training.3 for several years, librarians at the university of illinois have used chat transcripts for training graduate assistants and new employees and chat statistics for determining staffing. unlike other forms of reference interactions, chat offers a textual record of the conversation, so librarians have used this unique opportunity in a couple different ways. in a training exercise, students read through actual transcripts and are guided in recognizing both well-developed and less-than-ideal interactions. they are then asked to think about ways those chat conversations could have been improved and to share strategies for doing so. graduate assistant supervisors also use chat transcripts to evaluate the performance of individual graduate assistants, checking for appropriate levels of helpfulness and for adherence to the library’s chat policies. finally, part of the library’s assessment strategy looks at chat interaction numbers, such as chats per hour, the duration of each conversation, and the level of complexity of each conversation to help make decisions about optimal chat staffing levels. however, prior to the project described here, the library had not yet good night, good day, good luck | ozeran and martin 60 https://doi.org/10.6017/ital.v38i2.10921 analyzed the chat reference conversations on a large scale to understand the range and consistency of topics being discussed. while these uses of chat data have been successful, such a large body of information from patrons about the library and its collections and services seemed underutilized. in an environment of growing data-informed decision-making, both within the broader library community and at the university of illinois in particular, it was now an opportune time to implement this kind of largescale topic analysis. if common themes emerged from the chat interactions beyond simply showing the most frequently asked questions, these themes could inform the library’s reference services beyond just training for chat reference. for example, patterns in the number of citation questions could indicate the best times to offer a citation management tool workshop; multiple inquiries about a new resource or tool might prompt planning a new workshop; and repeated confusion regarding a service or policy may signal a need to bolster the online guides or faq. since the number of chat transcripts was so large, automating analysis through a programming language such as python seemed the best course of action. this article presents the results of a pilot project that tested the application of algorithmic topic modeling to chat conversations. the outcomes for this project included (1) determining if this method could be used to identify the most common chat reference topics in a semester; and (2) whether this information indicated if it could be used to inform reference services beyond just training for chat, such as improving faqs, workshops, the library website, or other instruction. literature review chat reference services are well established in academic libraries, and there are abundant examples in the literature exploring these services. however, there is a lack of research on ways to employ automated methods to analyze chat reference. numerous articles approach chat analysis via traditional qualitative methods, where research teams hand-code chat themes, topics, or question categories.4 schiller employed a tool called qda miner to partially automate the otherwise human-driven coding process, using the software to automatically generate clusters of manually created codes.5 only one paper appeared to explicitly address the issue primarily by using algorithmic analysis methods. in addition to conducting sentiment analysis, kohler applied three topic modeling algorithms to chat reference conversations at rockhurst university.6 kohler identified the algorithm of non-negative matrix factorization (nmf) as the “winning topic extractor” based on how evenly it distributed the topic clusters across all the chat conversations.7 the other algorithms kohler tested, latent dirichlet allocation (lda) and latent semantic analysis (lsa), had much more skewed distributions of topics. the most common topic identified by lda appeared in so many of the chat conversations that it was essentially meaningless as a category. lda is one the most well-established topic modeling algorithms, but as kohler found, it does not work very well with short texts like chat conversations. to supplement the lack of library research in this area, non-library research that has applied topic modeling to short texts was also reviewed. interestingly, although the nmf algorithm worked well for kohler’s analysis of library chat conversations, there was little mention of nmf in the nonlibrary literature. on the other hand, it was not surprising that lda was one of the most commonly discussed algorithms, either as an example of what doesn’t work or as a basis upon which a modified algorithm was created to perform better for short texts.8 another common algorithm information technology and libraries | june 2019 61 was biterm topic modeling (btm). proposed by cheng et al., btm takes pairs of words (biterms), rather than individual words, as the unit on which to base topics.9 by creating biterms, the researchers increased the number of items to sort into topics, thus mitigating a common problem with analyzing short texts. a final commonly used algorithm was the dirichlet mixture model (dmm).10 a key feature of dmm for analyzing short texts is that it assumes each text (in this project, each chat conversation) is associated with only one topic. while longer texts like articles or books likely encompass many topics, it is plausible that a chat conversation could be summarized in one topic. methodology at the time of this project (spring 2018), the library was using locally developed chat software called iwonder. the chat widget is embedded on the library homepage, on the “ask a librarian” page, in libguides, and within the library’s interface for its licensed ebsco databases. the chat service was available 87 hours per week at the time the data was collected. during the day, chat service is provided by a mix of librarians, library staff, and graduate assistants, most of whom are scheduled at the main library’s information desk. subject-specific libraries, including the engineering library, the agricultural and life sciences library, and the social sciences, health, and education library, also contribute many hours on chat reference from their respective locations. the evening and weekend shifts are all covered by graduate assistants from the university of illinois school of information sciences. the authors decided that one semester of chat transcripts would be the most appropriate corpus with which to work for this pilot project because it would encompass a substantive and meaningful (but also manageable) number of conversations. in preparation, institutional review board approval was received, and a graduate student completing a degree in information management from the school of information sciences was selected to assist with this project through the school’s practicum program. this practicum student is an experienced programmer, and his presence on the team allowed the project to proceed more quickly than if the authors had pursued the project without his expertise. to begin the project, all chat conversations from the spring 2017 semester were obtained by querying the local server using mysql workbench, limiting the query to chat logs between the dates 1/17/2017 and 5/12/2017 (inclusive). because each line of a chat conversation was saved as a separate line in the database, this meant retrieving approximately 90,000 lines of data. the actual text of the chat conversations was unstructured (by its nature), but the text was saved with related metadata. for instance, each chat conversation was automatically given a unique identifier, so the individual lines could be grouped into conversations and put in order by their timestamp. the 90,000 lines represented almost 6,000 individual conversations. the chat logs were cleaned using a combination of openrefine (primarily for ascii character cleanup) and python code to remove personally identifiable information (pii) and to make the data easier to analyze.11 by default, the chat software did not collect any information about patrons, but sometimes patrons volunteered pii because they thought it was needed to answer their questions. therefore, part of the cleaning process involved removing as much of this patron pii as possible, replacing it with the word “removed” to denote the change. in addition, library staff usernames were scrubbed by replacing each username with a generic “staff###”, where “###” was a unique (incremented) number assigned to each original username. this maintained good night, good day, good luck | ozeran and martin 62 https://doi.org/10.6017/ital.v38i2.10921 the ability to track a single staff member across multiple conversations, if desired, without identifying the actual person. another important part of the data cleaning was to remove urls, because these would be unnecessary in identifying topics, and they significantly increased the number of unique “words” that the analysis algorithms identified. the urls were nearly always saved within an <a> html tag, so most urls were easily identified for removal. the data cleaning process has been described here in a linear fashion for ease of understanding, but over the course of the project it was actually an iterative process, as more cleaning issues were discovered during analysis. based on the analyses performed in the related literature, the practicum student wrote code to test five topic modeling algorithms: (1) latent dirichlet allocation (lda), (2) phrase-lda (lda applied to phrases instead of words), (3) biterm topic modeling (btm), (4) dirichlet mixture modeling (dmm), and (5) non-negative matrix factorization (nmf). ultimately, the processing power and time required to implement btm meant that this algorithm could not be implemented for this project. however, for the other four models, lda, phrase-lda, dmm, and nmf, were all successfully implemented. all code related to this project, including the cleaning and analysis, are available on github (https://github.com/mozeran/uiuc-chat-log-analysis). results outputs of the lda, phrase-lda, dmm, and nmf modeling algorithms are shown in tables 1 through 4. after removing common stop words, the remaining words were put into lowercase and stemmed before topic modeling algorithms were applied. the objective of the stemming process was to convert singular and plural versions of a word to a hybrid form so that they are treated as the same word. thus, many words ending in “y” are shown ending in “i”. for instance, “library” and “libraries” would both be converted to “librari” and thus be treated as the same word. the phrase “easi search” refers to “easy search,” the all-in-one search box on the library homepage. the word “ugl” refers to the undergraduate library (ugl). the word “remov” showed up in the topic lists surprisingly frequently, probably because patron pii was replaced with the word “removed.” since explicitly denoting the removal of pii is unlikely to be of import, it makes sense in the future to simply remove the pii without replacement. table 1: lda (top 10 words in each topic) topic 1 music map laptop remov find ok

unfortun uiuc onlin wonder version graduat print seem way grad discussion interpreting the results of a topic model can be a bit of a guessing game. none of these algorithms look at the semantic meaning of words, so the resulting topics are not based on semantics. each algorithm simply employs a different method of mathematically determining the likelihood that words are related to each other. when this likelihood is high enough (as defined by the algorithm), the words are listed within the same topic. identifying topics mathematically is much quicker than a person hand-coding conversations. however, automatic classification also means that the resulting topics could make absolutely no sense to people, who understand the semantic meaning of the words within a topic. this lack of coherent meaning is most present in the results of the dmm model (table 3). for instance, the words that comprise topic 1 are the following: “work open chat way online say specify available day source.” it is difficult to imagine what overarching concept links all, or even most, of these words. only a few words appear to have any significance at all: “open” could refer to open access, or to the library’s open hours; “online” may refer to finding resources online, or the fact that a student is taking online classes; and “source” is likely some reference to a research resource. these words barely relate to each other semantically, and the remaining seven words don’t provide much clarification. thus, it appears that dmm is not a particularly good topic modeling algorithm for library chat reference. the results seen from the lda model (table 1) appear slightly more comprehensible. in topic 2, for instance, the words are as follows: “look search find help database thank use article research would.” while not all the words relate to each other, a common theme could emerge from the words look, search, find, database, article, and research. it’s possible that this topic 2 identified chat conversations where a patron needed help finding research articles. even topic 6, at first glance a silly list of words, makes some sense: “thank chat good know one night go okay think hi.” greetings and sign-offs probably comprised a good number of the total words in the corpus, so it is understandable that a “greetings” topic could be mathematically identified. overall, lda appears to have potential in topic modeling chat reference, but it probably needs to be further tweaked. when applying the lda model to phrases (table 2), the coherence increases within the phrases, but the topics are not always as coherent. topic 1 includes the following phrases: “interlibrary loan, lose chat, chat service, lower level, chat open, writer workshop, spring break, study room, call ugl, add chat.” each phrase, individually, makes perfect sense for the context of this library; as a collection, however, the phrases don’t comprise one coherent topic. four of the phrases explicitly mention chat services (an interesting meta-topic), while the rest appear completely unrelated. on the other hand, topic 10 does show more semantic relation between the phrases: “request book, request item, check book, double check, print copy, course reserve, copy available, physical copy, book available, copy past.” it seems pretty clear that this topic refers to books— whether on reserve, being requested, or checking if they are even available. with the wide difference in topic coherence, the phrase-lda algorithm is not perfect for topic modeling chat reference, but further exploration is warranted. information technology and libraries | june 2019 65 the final algorithm, nfm (table 4), is also imperfect. it is possible to distill each topic into an actual semantic concept, but there is almost always at least one word that makes it a little less clear. topic 5 probably provides the best coherence: “account log set vpn use password id say campus problem.” it seems clear this topic refers to identity verification, likely for off-campus use of library resources. the other topics given by the algorithm have more confusing elements, such as in topic 1 where the relatively meaningless words may, way, and say all appear. it’s interesting that kohler found nmf to work very well, while the results above are not nearly as coherent as those identified in her implementation.12 this is a perfect example of how the tuning of many different parameters can affect the ultimate results of each topic modeling algorithm. this is why the authors think it is worth continuing to explore how to improve the implementation of lda, phrase-lda, and nmf algorithms for chat conversations, as well as share the original code for others to test and revise. it will take many different projects at many different libraries before an optimum topic model implementation is found for chat reference. next steps for the most part, the more coherent results from the lda and nmf topic modeling algorithms support anecdotal understanding of the primary themes in chat conversations. currently, two members of the research & information services unit, the department responsible for scheduling the chat reference service at the main library, are examining the model outputs to determine whether any of the results are strong enough at this stage to suggest changes to services or resources. they will also share the results with the chat coordinators at other libraries on campus in case the results indicate changes for them. additionally, results will be shared with the library’s web working group, since repeated questions about the same services or locations may suggest the need to display them in a more prominent place on the library website or provide a more discoverable online path to them. since this was a pilot project that used a fairly small data set, it is anticipated that years of transcripts—along with improved topic model implementation—will reveal even more significant and robust themes. with the encouraging results of this pilot project, there is much to continue to explore.13 one future question is whether there are differences between fall and spring semesters. if some topics arise more frequently in one semester than the other, perhaps the library needs to offer more workshops during that semester. alternatively, perhaps support materials should be created (such as handouts or online guides) that emphasize the related services and place them more prominently, while withdrawing or de-emphasizing them in the other semester. another area for further analysis is how the topics that emerge in the late-night chat interactions compare to other times of day. this will help the library design more relevant training materials for the graduate assistants who staff those shifts, or potentially change who is staffing the shifts. also of interest is comparing the text written by the chat operators versus the chat users, as this would further spotlight the terminology that patrons use. if patrons are using significantly different terms from staff, then modifying the language of the library’s website may reduce confusion. there are also improvements to make to the data cleaning process, such as better identifying when to remove stop words and when to remove punctuation. these steps weren’t perfectly aligned, which is why; for example, the “ll” that appears in topic 3 of the phrase-lda results (table 2) is most likely a mutation of the contractions like “i’ll,” “we’ll,” and “you’ll.” generating “ll” as a word from multiple different contractions not only created a meaningless word, but since “ll” good night, good day, good luck | ozeran and martin 66 https://doi.org/10.6017/ital.v38i2.10921 occurred more frequently than any unique contraction, it was potentially treated as more important by the topic modeling algorithms. conclusion this project has demonstrated that topic modeling is one possible way to employ automated methods to analyze chat reference, with mixed success. the library will continue to improve chat reference analysis based on this project experience. the authors hope that other libraries will use the lessons from this project and the code in github as a starting point to employ similar analysis for their own chat reference. in fact, a related project at the university of northern iowa library is evidence of growing interest in topic modeling of chat reference transcripts.14 considering how frequently patrons use chat reference, is it important for libraries to explore and embrace whatever methods will allow them to assess and improve such services. acknowledgements the authors wish to acknowledge the research and publication committee of the university of illinois at urbana-champaign library, which provided support for the completion of this research. many thanks are owed to xinyu tian, our practicum student, for the extensive work he did in identifying

dowling <tdowling @ohiolink .edu> to : multiple recipients of list <web41ib @sunsite.berkeley.edu> sent : thu, 19 aug 1999 06:07 :08 -0700 (pdt) subject: [web4lib] pixel s izes for web pages dan marmion pages." he is responding to a query that asked if web site developers should assume the standard monitor resolution is 640x480 pixels, or something else. you may want to consult the web4lib archive for comments from the last few merry go-rounds on this topic. monitor size in inches is different from monitor size in pixels , which is different from window size in pixels, which is d ifferent from the rendered size of a browser's default font. not only are these four measurements different, they operate almost wholly independently of each other . so a statement like "i have trouble reading text at 600x800" puts the blame in the wrong place . html inherently has no sense of screen or window dimensions. many web designers will argue that the only aspects to a page with fixed pixel dimensions should be inline images; such designers typically restrain their use of images so that no single image or horizontal chain of images is wider than, say, 550px (with obvious exceptions for sites like image archives where the main purpose of a page is to display a larger image) . outside of images, find ways to express measurements relative to window size (percentages) or relative to text size (ems). users detest horizontal scrolling. in my experience, users with higher screen resolutions and/or larger monitors are less likely to run any application full screen; average window size on a 1280x1024 19" or 21 " monitor is very likely to be less than b00px wide. (the browser window i currently have open is 587px wide and 737px high .) i applaud your decision to support web access for the visually impaired . since that entails much , much more than monitor resolution, i trust the people actually writing your pages are familiar with the web content accessibility guidelines. it is actually possible to design web sites that are equally usable , even equally beautiful, under a wide range of viewing conditions. failing to accomplish that completely is understandable; failing to identify it as a goal is not. my recommendations to your committee would be a) find a starting point that isn't tied up in presentational nitpicking; b) find a design that looks attractive anywhere from 550 to 1550 pixels wide; c) crank up both your workstations ' resolution and font size; and d) continue to run your browsers in windows that are approximately 600 to 640 pixels wide . thomas dowling ohiolink ohio library and information network tdowllng

the ala annual conference in washington, d.c. are well underway. despite that discon­ nect in time, i am confident that the level of enthusiasm will continue uninterrupted between the two events. indeed, the midwinter meeting was highly charged with positive energy and excitement. the feelings are reignited if you listen to the numerous podcasts now found on the lita blog. the lita bloggers and podcasters were omni­ present reporting on all of the meetings and recording the musings of the lita top tech trendsters. by the time you have read this you will have also, hopefully, cast your ballot for lita officers and directors after having had the opportunity to listen to brief podcast interviews with the candidates. the lita board approved the election pod­ casts at the annual conference in new orleans. thanks to the collaborative efforts of the nominating committee and the bigwig members, we have this new input into our voting decision­making. the most exciting aspects of the midwinter meeting were the face­to­face, networking opportunities that make lita so great. the lita happy hour crowd filled the six arms bar and lit it up with the wonderful lita glow badges. what was particularly gratifying to me was the number of new lita members alongside those of us who have been around longer than we care to count. the net­ working that went on there was phenomenal! the other important networking opportunity for lita members was the lita town meeting led by lita vice president mark beatty. the room was packed with eager members ready to brainstorm about what they think lita should be doing after consuming a wonderful breakfast. lita’s sponsored emerging leader, michelle boule, and mark have collated the findings and will be working with the other emerging leaders to fine­tune a direction. the podcast interview of michelle and mark is an excellent summary of what you can expect in the next year when mark is president. as stated earlier, this is my last president’s column, which means my term is winding down. using lita’s strategic plan as a guide, i have worked with many of you in lita to ensure that we have a structure in place that allows us to be more adaptable to the rapidly chang­ ing world and to make sure that lita is relevant to lita members 365 x 24 x 7 and not just at conferences and lita national forum. attracting and retaining new members is critical for the health of any organization and in that vein, mark and i have used the ala emerging leaders program as a jumping off point to work with lita’s emerging leaders. the bigwig group is foment­ ing with energy and excitement as they rally bloggers and have this past year launched the podcasting initiative and the lita wiki. all of these things are making it easier for members to communicate about issues of interest in their work as well as to conduct lita business. the lita blog had over nine thousand downloads of its podcasts in the first three weeks after midwinter which confirms the desire for these types of communications! i appointed two task forces that provided recommen­ dations to the lita board at midwinter. the assessment and research task force has recommended that a perma­ nent committee be established to monitor the collection of feedback and assessment data on lita programs and services. having an established assessment process will enable the board to know how well we are accomplishing our strategic plan and to keep us on the correct course to meet membership needs. the education working group has recommended the merger of two committees, the education and regional institutes committees, into one education committee. this merged committee will develop a variety of educational opportunities including online and face­to­face sessions. we hope to have both of these committees up and going later in 2007. happily, the feedback from the town meeting parallels the recom­ mendations of the task forces. the board will be revisit­ ing the strategic plan at the annual conference using information gathered at the town meeting. we will also be looking at what new services we should be initiating. all arrows seem to be pointing towards more educational and networking opportunities both virtual and in person. i anticipate that lita members will see some great new things happening in the next year. i have very much enjoyed the opportunity to serve as the lita president this past year. the best part has been getting to know so many lita members who have such creative ideas and who roll up their sleeves and dig in to get the work done. i am very grateful for everyone who has volunteered their time and talents to make lita such a great organization. bonnie postlethwaite (postlethwaiteb@umkc.edu) is lita

international students angela sample information technology and libraries | march 2020 https://doi.org/10.6017/ital.v39i1.11723 dr. angela sample (asample@oru.edu) is head of access services, oral roberts university abstract throughout its early years, the oral roberts university (oru) library held a place of pre-eminence on campus. oru’s founder envisioned the library as central to all academic function and scholarship. under the direction of the founding dean of learning resources, the library was an early pioneer in innovative technologies and methods. however, over time, as the case with many academic libraries, the library’s reputation as an institution crucial to the academic work on campus had diminished. a team of librarians is now engaged in programs aimed at repositioning the library as the university’s hub of learning. toward that goal, the library has long taught information literacy (il) to students and faculty through several traditional methods, including one-shot workshops and sessions tied to specific courses of study. now, in conjunction with disseminating augmented, virtual, and mixed reality (avmr) learning technologies, the library is redesigning instruction to align with various realities of higher education today, including uses of avmr in instruction and research and following best practices from research into serving 1. online learners; 2. international learners not accustomed to western higher-education practices; and 3. learners returning to university study after being away from higher education for some time or having changed disciplines of study. the library is innovating online tutorials targeted for nontraditional and international graduate students with various combinations of avmr, with the goal to diminish library anxiety. numerous library and information science studies have shown a correlation between library anxiety and reduced library use, and library use has been linked to student learning, academic success, and retention.1 this paper focuses on il instruction methods under development by the library. current indicators are encouraging as the library embarks on the redesign of il instruction and early development of inclusion of avmr in il instruction for nontraditional and international students. literature review the patron approaches the reference desk, with eyes downcast. in a voice so soft that it is barely above a whisper, the patron mumbles, “is this where i can get help with research?” some variation on the above scenario is an occurrence long familiar to academic reference librarians. in 1986, mellon put a name to this nervousness of patrons; she called it library anxiety.2 mailto:asample@oru.edu information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 2 since then, librarians have implemented various measures to help put patrons at ease and minimize their library anxiety. scholars have studied many of these measures aimed at reducing library anxiety, both to determine the efficacy of such interventions and to understand better the causes of library anxiety. this paper describes one library’s intervention using a virtual-reality tour of the library to learn about some of the services available at the library prior to their initial visit in an attempt to reduce some aspects of their library anxiety. library anxiety library and information science (lis) researchers have long recognized anxiety related to libraries and research can have a detrimental effect on students. mizrachi described library anxiety as the feeling of being overwhelmed, intimidated, nervous, uncertain, or confused when using or contemplating use of the library and its resources to satisfy an information need. it is a state-based anxiety that can result in misconceptions or misapplications of library resources, procrastination, and avoidance of library tasks.3 since mellon’s theoretical framing of library anxiety in 1986, researchers have studied a number of library-related anxieties, including research anxiety, information literacy anxiety, library technophobia, and computer anxiety. various studies have focused on different groups of students—freshmen, nontraditional students, and international students, to name a few—who may experience higher levels of library anxiety. another area that has been of interest to researchers is the study of the efficacy of various measures aimed at reducing the library anxiety of students. causes and factors researchers have found several causes of library anxiety. in her seminal article, mellon used a grounded theory approach to understand and “describe students’ fear of the library as library anxiety.”4 mellon noted most of the students in her study described their feelings as being lost in the library, which mellon stated “stemmed from four causes: (1) the size of the library; (2) a lack of knowledge about where things were located; (3) how to begin; and (4) what to do.”5 head and eisenberg also found a majority of students (84 percent) had difficulties in knowing where to begin.6 bostick and later jiao and onwuegbuzie named “five general antecedents of library anxiety . . . namely, barriers with staff, affective barriers, comfort with the library, knowledge of the library, and mechanical barriers.”7 barriers with staff are the feelings students have regarding the accessibility and approachability of library staff.8 affective barriers are students’ self-perceptions of their competence in using the library and library resources. affective barriers’ arise from feelings of inadequacy and can be heightened by the perception that others possess library skills that they alone do not.9 comfort with the library deals with the student’s perception of the library as a “safe and comforting environment.”10 knowledge of the library is students’ knowledge of “where things are located and how to find their way around in the building.”11 mechanical barriers refer to students’ perception of the reliability of machines in the library (e.g., copiers, printers, computers, etc.).12 researchers focused on investigating the information-seeking behavior of students have identified stages of library anxiety. in her work, kuhlthau identified six stages of information seeking in information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 3 which students may experience library anxiety: task initiation, topic selection, prefocus exploration, focus formulation, information collection, and search closure.13 in blundell’s presentation of her theoretical model of the academic information search process (aisp) of undergraduate millennial students (figure 1), she described the varying levels of anxiety students may feel throughout this process depending upon their success at finding needed information.14 anxiety at stage 2: development/refinement “ranges from mild to extreme, depending on the success of the student’s aisp in finding information he/she believes is appropriate for addressing the academic need.”15 at stage 3, “based on information located through the aisp in stages 1 & 2, [the] student either fulfills [the] academic need with minimal anxiety, refocuses aisp with mid to high-level anxiety, or abandons the academic need completely with high/extreme levels of anxiety.”16 figure 1. blundell aisp model.17 although blundell studied undergraduate millennial students’ information-seeking behaviors, the same behaviors may also be descriptive of other groups of students. blundell omitted anxiety at or prior to stage 1 when the assignment is received by the student. one reason for the omission of anxiety in blundell’s model at stage 1 may be a seemingly paradoxical finding by many researchers regarding students’ inflated belief in their research skills as compared to their actual level of information literacy (il) skills.18 students with a high self-assessment of their il skills may feel confident at the onset of research, only experiencing anxiety when encountering low success rates when searching for information or when experiencing information overload. however, many other students may experience anxiety at the onset of receiving an assignment, particularly on a information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 4 topic in which they have little or no knowledge. others may experience anxiety if they realize they do not know where to look for information, how to use library research tools, or feel apprehension at the thought of asking for help from a librarian. for example, library anxiety can result from the requirements of the assignment; most professors require peer-reviewed sources. many new students do not know what a peer-reviewed source is, much less how to find one. indeed, many of the causes of library anxiety described from mellon’s and later jiao’s and onwuegbuzie’s work can be positioned throughout all six of kuhlthau’s and all three of blundell’s stages of information seeking and could explain some of the potential steps blundell noted in her model. negative effects in addition to the obvious discomfort students might feel, library anxiety, as with other forms of anxiety, can have a detrimental effect on students’ academic performance. as mellon noted, “students become so anxious about having to gather information in a library for their research paper that they are unable to approach the problem logically or effectively.”19 the findings from jiao’s and onwuegbuzie’s numerous studies support the negative effect library anxiety can have on students’ academic performance in various ways, including research performance, research proposal writing, and study habits.20 research has also shown the link between higher levels of library anxiety and avoidance of the library.21 avoidance of the library could hinder students’ academic performance or retention; studies have linked library use to higher gpas and increased retention rates.22 other negative effects of library anxiety include the reluctance of students to ask for help from a librarian and the tendency to procrastinate until it is too late to do well on assignments. when library anxiety is at a level high enough to cause students to enter a panic mode, logical thinking, the ability to apply existing skills, and building or acquiring new skills can be impaired. at-risk student groups acknowledging the negative effects library anxiety can have on students’ academic performance, several studies have looked to determine whether particular demographic groups of students experience library anxiety at higher rates and what factors or causes may be most prevalent in the causes of library anxiety for a particular group. in one study conducted by jiao, onwuegbuzie, and lichtenstein, students who fell into the following groups tended to have the highest levels of library anxiety: “male, undergraduate, not speak english as their native language, have high levels of academic achievement, be employed either partor full-time, and visit the library infrequently.”23 some studies have focused on learning more about the library anxiety of a particular group. some of the groups investigated include graduate, international, and nontraditional students. still others have focused on possible racial differences in the prevalence of library anxiety. although a few studies have found library anxiety to be higher for undergraduate students than graduate students, one of the most often-studied groups at risk for library anxiety has been graduate students.24 these researchers have looked at a number of factors in relation to graduate students’ library anxiety. in an early study, they found graduate students with the preferred learning style of visual learners tend to have higher levels of library anxiety. 25 in another study of graduate students, they examined the relation between library anxiety and trait anxiety, defined as “the relative stable proneness within each person to react to situations seen as stressful. ”26 jiao and onwuegbuzie, together with bostick, investigated the potential relationship between race and library anxiety in 2004, which study they replicated in 2006. in both, the researchers found information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 5 caucasian american graduate students reported higher levels of library anxiety than their african american counterparts.27 another group frequently examined in library anxiety studies is international students. mizrachi noted “studies involving international students in american universities consistently show their levels of library anxiety to be much higher than their american peers.”28 onwuegbuzie and jiao found international esl students “had higher levels of library anxiety associated with ‘barriers with staff,’ ‘affective barriers,’ and ‘mechanical barriers,’ and lower levels of library anxiety associated with ‘knowledge of the library’ than did native english speakers.”29 later, jiao and onwuegbuzie found the most prevalent causes of library anxiety for international students were mechanical barriers (library technology) as the greatest source, followed by affective barriers. 30 in the more recent pilot study by lu and adkins, the greatest barriers for international students were affective and staff barriers, while mechanical barriers, such as technologies, were no longer a significant cause of anxiety for most.31 collins and veal found adult learners in their study had the highest degree of library anxiety pertaining to affective barriers. 32 in their study, kwon, onwuegbuzie, and alexander revealed graduate students who had higher levels of library anxiety resulting from affective barriers and knowledge of the library had weaker critical-thinking skills, lower self-confidence, less inquisitiveness, and reduced systematicity (“less disposed toward organized, logical, focused, and attentive inquiry”).33 kwon found similar results in undergraduate students.34 interventions recognizing the multiple causes and multidimensional aspects of library anxiety, librarians have devised a number of interventions aimed at addressing one or more of its causes. some of the means to address barriers with staff have focused on outreach, engaging library instruction, online presence, and other similar efforts to reach students and provide needed support for students’ research. librarians have used information literacy instruction (ili), reference desk consultations, and print and online guides to address library anxiety stemming from affective barriers, knowledge of the library, and even the mechanical barriers arising from lack of technology skills. a common intervention is ili, which several studies have found to have some success in reducing students’ library anxiety. bell explored students’ levels of library anxiety before and after a onecredit il course.35 platt and platt examined the efficacy of two 50-minute ili sessions, required of students enrolled in the research methods in psychology course, in reducing library anxiety, which found “the greatest changes . . . were related primarily to knowledge of what resources are available in the library and how to access them.”36 in contrast to the typical one-session il class, fleming-may, mays, and radom investigated and found a three-workshop instruction model correlated with students’ increased confidence in using the library and lessening library anxiety. 37 notwithstanding the benefits of library instruction sessions for students in relieving library anxiety, pellegrino found students were far more likely to ask a librarian for help when their instructor, rather than a librarian, encouraged or required them do so.38 by familiarizing students with the location and arrangement of library services in the building, library orientations have been found to help relieve library anxiety. 39 library orientations primarily aim to address one of the causes of library anxiety: a lack knowledge of the library. these orientations often introduce students to various library staff, which may also help with the dimension of library anxiety due to barriers with staff. information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 6 other interventions have been attempted with some success. martin and park found students were more apt to request assistance from the librarian if persuaded the consultation would save time. 40 mcdaniel found in a study of graduate students that the use of peer mentors was effective in reducing affective barriers.41 robbins discussed the use of library events to help ease students anxiety, but found in the follow-up survey many students were unaware of the events.42 diprince et al. discussed ways the use of a print guide can help alleviate library anxiety. 43 oru library oral roberts university the oru library serves the students, faculty, and staff of oral roberts university (oru). oru is a small, private, not-for-profit, liberal arts college located in tulsa, oklahoma. founded in 1963 by oral roberts, enrollment is approximately 3,600 students. oru is an interdenominational christian institution focused on a whole-person education of spirit, mind, and body. oru offers more than 150 majors, minors, and pre-professional programs in a range of degree fields, from business, biology, engineering, nursing, ministry, and more.44 history “the first building will be the library which is the core of the whole academic structure.”45 —oral roberts (1962) from the founding of oru, founder oral roberts had a vision of the library’s centrality to academics.46 this set a precedent early in the history of oru library of the importance of the library to the academic work of the students and faculty of oru. expanding on traditional views of the function of an academic library to serve mainly as the repository of books and articles, through the vision of early library administrators, oru library emerged as one of the early adopters of electronic technology with the dairs (dial access information retrieval system) computer.47 throughout the years, due to a number of factors, the oru library receded from the forefront of pre-eminence in academics on campus. library practices followed the general trend of academic libraries. the oru library continued to acquire needed materials (e.g., books, journals, access to databases). library instruction likewise kept up with current models of instruction. the typical method of instruction to undergraduates has been teaching one or two sessions to a class at the request of the instructor. on largely the efforts of the instruction librarian, il became a required component of undergraduate education at oru. with rare exceptions, undergraduate students at oru are required as a part of comp 102: composition ii to attend two sessions of an il course. other forms of ili include workshops and sessions for undergraduates working on their senior papers and other sessions for graduate and postgraduate students, all typically at the request of the instructors of classes. with the new addition of augmented, virtual, and mixed reality (avmr) learning technologies, at the behest of their dean, oru librarians have begun to look at ways to incorporate these technologies into their classes and daily work. several oru instructors are using avmr technologies in their classes.48 to help prepare students for the use of these technologies in their classes, one oru instruction librarian has begun to introduce students to avmr technologies. other oru instruction librarians are exploring ways to use avmr technologies to create visualizations of library and research concepts, such as a 3d visualization of how boolean logic information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 7 works in database searches. oru instruction librarians are also exploring ways to incorporate avmr technologies into a new program of online ili. although still in very early stages of planning, the proposed online ili will include a virtual tour of the library. this paper focuses on the implementation and early feedback from a formative assessment on a virtual tour of the oru library. oru modular students in addition to traditional 15-week semesters, two colleges at oru offer graduate modular programs, the college of education and the college of theology and ministry. many of the students who enroll in these programs are nontraditional students who are returning to college after some time. several of these students work full-time jobs and have family obligations in addition to their academic work. often, these students are not local to the tulsa campus; several are us students who live out of state and many others are international students. the modular classes offered by both programs can be a hybrid of online and modular format. the college of theology and ministry offers one-week courses on campus; the college of education offers two-and-a-half-day on-campus classes. modular classes are intensive due to the compressed nature of the curriculum. often, modular students are visiting campus for the first time, and in addition to locating their classes, are very busy with coursework. adding to these pressures, modular students may be using computer technologies in new ways. navigating the library’s resources is yet another stressor for many of these students. for students who are not familiar with the operations of an academic library, they may not be aware of library services nor how to access those services. the project in january 2017, the global learning center opened on the campus of oru. one hallmark of this renovated structure is the integration of avmr technologies.49 despite several professors on campus from various disciplines and colleges implementing avmr into their curriculum, students’ use of the facilities was somewhat lower than had been hoped. in the fall 2018 semester, the idea of creating a virtual tour of the oru library arose from a conversation between the author and a colleague, dan eller. eller described an online ili course he envisioned for oru’s graduate theology modular students. as a part of this course, he envisioned a virtual tour that could help students by reducing their library anxiety. early in 2019, oru’s associate vice president of technology and innovation, michael mathews, contacted dr. mark roberts, dean of learning resources (of which the oru library is a part) to propose making avmr learning technologies available through the oru library. dean roberts agreed and created an avmr team of library faculty to oversee this project. in the spring 2019 semester, the oru it department sent one of their employees, stephen guzman, to work with the library’s avmr team to set up an avmr station and work in the library to help make these new technologies available and known to oru students. in addition to other avmr projects guzman helped the library’s avmr team begin, he volunteered to take the 360 images when he learned of the library’s desire to create a virtual tour of the library. guzman also helped in the selection of editing software, 3dvista, for which the library acquired a license. working with the 360 images guzman took and stitched together, the author used 3dvista to create a virtual tour of the library. this software allows for the addition of elements to the 360 images that make up the virtual tour to enhance the viewer’s experience and to provide information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 8 information and hyperlinks to external webpages with more information. some of the elements added to the oru library virtual tour are hotspots that enable a viewer to move from one area to another, icons that present pop-up windows with more information, and other icons that link to the online profiles of various library faculty. throughout the tour, consistent use of icons for the same functions is maintained. for example, icons with arrows allow the viewer to move from one location to another (figure 2), while icons with question marks displayed over library personnel (figure 3) open the personnel’s profile webpage when clicked. icons that contain the letter “i” feature pop-up windows with information and related links. the tour begins from outside the building so new visitors will be able to recognize the building when they arrive on campus (figure 4). viewers can navigate through subsequent 360 images by clicking on the arrow icons so the viewer virtually travels the same path they will follow to enter the library when on campus. there are two other options to navigate the tour. the viewer can click on the small icons of scenes displayed on the left side of the screen to move to another area. the floor plans displayed at the upper right of the screen have red dots indicating the location of various scenes and, when clicked, move the viewer to that scene. figure 2. avmr station near the reference desk, oru library virtual tour. other elements of the tour include small icons of the scenes on the left of the screen. beneath these icons are the names of the various areas. the title of the current scene appears in yello w lettering, providing information to help orient the viewer. small floorplans located in the upper right side of the screen offer additional information on the location of the area (figure 3). viewers can toggle these floorplans on and off. another feature supplying location information is the dropdown menu for the floorplans (the dark blue bar at the upper right of the screen) which shows the floor level of the building on which the area is located. in the lower right of the screen, an information icon is available with details on what behavior to expect when clicking on icons and a description of the various ways to navigate the tour. information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 9 figure 3. dean mark roberts near alexa and the self-checkout station at the circulation desk, oru library virtual tour. figure 4. oru campus, oru library tour. information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 10 methodology the aim of the virtual tour of the library is to reduce several dimensions of students’ library anxiety. the primary goal of the tour is to reduce anxiety related to knowledge of the library by familiarizing students with images and information regarding the building prior to their arrival on campus. another aim is to reduce barriers with staff, which we address by proving information along with images of library faculty. affective barriers and mechanical barriers are two of the most prevalent causes of library anxiety, which the intervention of the tour does not directly address. the hope is, however, that with the minimization of any anxiety stemming from knowledge of the building and barriers with staff, students will be encouraged to consult with librarians, particularly as information on the variety of ways to contact librarians is included on the information pop-up window on the reference desk. preand post-surveys the preand post-surveys administered to students included 42 statements from bostick’s library anxiety scale. bostick’s library anxiety scale, developed in 1992, is a 5-point likert scale survey instrument that contains 43 statements. the pre-survey also contains demographic questions. the one statement omitted from bostick’s original survey was number 40, “the change machines are always out of order,” as the oru library does not have change machines.50 with the exception of the demographical questions, the post-survey is the duplicate of the pre-survey, with the same 42 statements. although several researchers have adapted bostick’s library anxiety scale, such as blundell’s adaptation to add “elements related specifically to information technology (both hardware such as computers, and software such as online research databases),”51 for the purposes of this preliminary inquiry, the researcher decided to use the original questions from the library anxiety scale. the original statements were used because reduction of library anxiety stemming from information technology use was not a goal of this study. administration of survey a link to the pre-survey was posted on the homepage of the oru library. the author sent email invitations containing a link to the pre-survey to students enrolled in the june 2019 summer modular theology classes. the author met with groups of education modular students during the week they were on campus (june 24–30, 2019) to recruit participation. in a library session, another librarian encouraged her modular students to participate in the study. at the end of the pre-survey, a unique number and instructions to note the number were provided to participants to be used to log in to the post-survey. the link to the virtual tour appeared on the final screen of the pre-survey. the link to the post-survey was provided on the same page as the virtual tour, allowing participants to navigate to the post-survey when desired. the surveys asked for no identifying information; however, the unique number provided on the pre-surveys and entered by the participants on the post-surveys allowed the researcher to link the participants’ responses to both surveys. once the results were downloaded, each of the participants’ preand post-survey responses were coded p1 through p7 to track any potential effects of the virtual tour on participants’ responses. because of the low rate of participation, formal statistical analyses were not applied to these findings. the results were examined in two ways. each participants’ preand post-survey responses were compared to determine if responses changed from preto post-survey. the total number of responses on each point of the likert scale information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 11 to each of the 42 statements were examined to determine trends in participants’ levels of library anxiety. results although approximately 100 students enrolled in either the graduate theology or graduate education modular classes visited the campus june 24–30, 2019, participation in this preliminary study was extremely low. to date only seven participants have completed both the preand postsurveys. the responses from this formative assessment will be used by the oru library to guide future iterations of the virtual library tour and inclusion in ili. the following discusses initial findings from the preand post-surveys. most of the participants reported little or no discomfort or anxiety with using the library. all participants indicated they are us citizens, and all indicated some level of familiarity with the library. four reported they had often visited the library, three responded they had visited the library previously, but not often. of the seven participants, five indicated they are graduate students, one marked “other,” and one reported doctoral-student status. ages of the participants varied from one at 20–29, one 30–39, two 40–49, and three at 50 years or over. the following describes the effect the virtual tour of the library had on participants’ responses. interestingly, one participant showed no change in responses from preto post-survey. note: bostick’s original categorization of the statements have been retained for all 42 of the statements on both instruments. knowledge of the library the principal aim of the virtual tour was to reduce library anxiety related to knowledge of the library by acquainting students with “where things are located and how to find their way around in the building.”52 bostick categorized 5 of the 42 statements as knowledge of the library. based on participants’ responses, there is some indication the tour did help acquaint students with the library. the changes in participants’ responses showed a greater positive trend after viewing the virtual tour; although on two statements, responses showed a negative trend (table 1). table 1 shows the questions on which participants had a change in their responses from preto postsurvey. the number in the positive column indicates the number of participants whose responses displayed a favorable change in the perceptions of participants to that statement following the virtual tour. the number in the negative column shows the number of participants whose responses on the post-survey showed a negative effect of the virtual tour on their responses. statement positive negative i don’t feel physically safe in the library. 1 1 i enjoy learning new things about the library. 3 1 i want to learn how to do my own research. 1 the library is a safe place. 2 the library is an important part of my school. 2 totals 9 2 table 1. statements in knowledge of the library category, which showed change on post-survey. the number of responses of strongly disagree statements in this category were unchanged from preto post-survey. the only statement that received any responses of strongly disagree was five information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 12 to the statement “i don't feel physically safe in the library.” taken together with the two responses of disagree to this statement, all the participants feel safe in the library. to the statement “the library is a safe place,” all seven participants answered either agree (five on pre-survey, four on post-survey) or strongly agree (two on pre-survey, three on post-survey) (figure 6). curiously, responses to “i enjoy learning new things about the library” changed from no responses of disagree on the pre-survey to one response of disagree on the post-survey. the other shift in the number of responses of disagree was on the statement “the library is an important part of my school” (two on pre-survey, one on post-survey), indicating a slight improvement (figure 5). figure 5. comparison of strongly disagree and disagree responses in knowledge of the library category. to the statements in this category, none of the respondents replied undecided, except to the statement “i enjoy learning new things about the library.” there was one undecided response on the pre-survey and no responses of undecided on the post-survey to this statement. the other change in this category was to the statement “the library is an important part of my school,” which moved from no responses of undecided on the pre-survey to one undecided on the postsurvey. the respondents, for the most part, wanted to learn to do their own research, with five responses of agree or strongly agree on both the preand post-surveys. five of the participants felt the library is of importance (one agree and four strongly agree). six of the seven participants reported they enjoy learning new things about the library. the shift in responses from five agree and one strongly agree on pre-survey to two agree and four strongly agree indicates the tour might have affected participants’ views on this statement (figure 6). information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 13 figure 6. comparison of strongly agree and agree responses in knowledge of the library category. affective barriers while not a direct goal of the virtual tour, the responses of participants showed the most gains on the post-survey within the category of affective barriers. this seems to indicate that viewing the virtual tour improved students’ self-perceptions of their competence in using the library and library resources. out of the 42 statements on each of the instruments, 12 are in bostick’s category, affective barriers. the statements in table 2 are those on which participants had a change in their responses from preto post-survey. the numbers in the positive column indicate the number of participant responses, which improved on the post-survey. a number in the negative column indicates participants’ post-survey responses that moved in a negative direction. statement positive negative a lot of the university is confusing to me. 2 i am unsure how to begin my research. 2 i can never find things i need in the library. 3 i don’t know what resources are available in the library. 2 i don't know what to do next when the book i need is not on the shelf. 1 i feel comfortable using the library. 3 i get confused trying to find my way around the library. 2 i’m embarrassed that i don’t know how to use the library. 1 1 the directions for using the computers are not clear. totals 17 1 table 2. statements in affective barriers category, which showed change on post-survey. information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 14 looking at the responses to statements in this category reveals some possible effects of the tour and some potential areas of library anxiety. the responses to “i don’t know what resources are available in the library” were split on the pre-survey, with three responses of agree, one of strongly agree, one undecided, one of strongly disagree, and two of disagree. the post-survey responses showed almost no change; the only change was one additional response of undecided, with no strongly agree responses (figures 7.1, 8.1, 9.1). these findings indicate more information on what sources are available to patrons may be needed on the virtual tour. most of the respondents indicated confidence about where to begin research. on both preand post-surveys, there were five responses of strongly disagree or disagree to the statement “i am unsure how to begin my research” (figure 7.1). most indicated they feel confident in using the library based on the responses to the statements “i’m embarrassed that i don’t know how to use the library,” “i feel comfortable using the library,” “i can never find things in the library,” and “i get confused trying to find my way around the library” (figures 7.1, 7.2, 9.1, 9.2). responses were equally positive to the statements “the library won't let me check out as many items as i need,” “a lot of the university is confusing to me,” “i don’t know what to do next when the book i need is not on the shelf,” and “i can’t find enough space in the library to study” (figures 7.1, 7.2, 8.1, 8.2, 9.1, 9.2). responses were divided on the statement “i feel like i’m bothering the reference librarian if i ask a question” (figures 8.2, 10.2). this finding needs further research to determine what is causing students to feel reluctance to ask the librarian for assistance. figure 7.1. comparison of strongly disagree and disagree responses in affective barriers

of mechanical barriers. it is unclear how the virtual tour might have caused the improvement in participants’ perception of the reliability of machines in the library. statement positive negative the computer printers are often out of paper. 1 the copy machines are usually out of order. 1 totals 2 table 3. statements in mechanical barriers category, which showed change on post-survey. in this category, on both the preand post-surveys, there was one strongly disagree response to both statements. no respondents replied agree or strongly agree to the statements in this category. responses of disagree to both statements increased one from one disagree response on the pre-survey to two disagree responses on the post-survey. the number of undecided responses fell from five to four on the post-survey. as noted above, it is not clear what caused the change in responses. barriers with staff a secondary goal of the tour was to reduce barriers with staff and thus to reduce library anxiety by providing information with images of library faculty. by providing information and images of the library faculty, this study sought to reduce the anxiety students may have regarding the accessibility and approachability of library staff. in this category, participants showed some positive effects of the virtual tour on how participants viewed library staff. however, the responses of participants exhibited the most variability in this category, with almost an equal number of responses being positive or negative after viewing the tour. the reasons for this information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 18 variance are unclear. in future studies, additional space for comments will be included on the surveys as well as possible follow-up focus-group discussions to determine the causes of negative trends in responses. table 4 shows the statements within this category on which participants had a change in their responses from preto post-survey. the number in the positive column indicates how many participant responses changed in a favorable direction on the post-survey. the number in the negative column indicates the number of participants whose post-survey responses moved in a negative direction. on the survey instruments, 12 of the 15 statements categorized as bostick’s barriers with staff showed changes in responses. statement positive negative i can always ask a librarian if i don’t know how to work a piece of equipment in the library. 1 i can’t get help in the library at the times i need it. 1 1 if i can’t find a book on the shelf the library staff will help me. 2 2 library staff don’t have time to help me. 1 1 the librarians are unapproachable. 2 the library is a comfortable place to study. 2 the library staff doesn’t care about students. 1 3 the library staff doesn’t listen to students. 1 the reference librarians are not approachable. 2 the reference librarians are unhelpful. 2 the reference librarians don’t have time to help me because they’re always busy doing something else. 1 1 there is often no one available in the library to help me. 2 1 totals 15 12 table 4. statements in barriers with staff category, which showed change on post-survey. the findings in the category, overall, were favorable. most feel the librarians and library staff care and are responsive and available to students. pre-survey responses indicated one or two of the participants felt librarians are unapproachable or unhelpful. post-survey responses reflected a positive change in participants’ views on librarians’ approachability and helpfulness. participants also reported the library to be a comfortable study location and that the rules are reasonable (figures 10.1, 10.2, 11.1, 11.2, 12.1, 12.2). information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 19 figure 10.1.

category. comfort with the library according to collins and veal, comfort with the library is students’ perceptions of the library as a “safe and comforting environment.”53 out of the 42 statements, bostick placed 8 within this category, all of whom showed some change in responses from pre-survey to post-survey. the changes reflected in this category were positive, but it is unclear how the virtual tour might have influenced participants’ perceptions on statements such as “there is too much crime in the library” or “good instructions for using the library’s computers are available.” further investigation is needed to determine what may account for changes in perception on statements such as these. table 5 depicts the changes, both positive and negative, in participants’ responses on the statements in this category. information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 22 statement positive negative good instructions for using the library’s computers are available. 2 i don’t understand the library’s overdue fines. 1 2 i feel comfortable in the library. 2 i feel safe in the library. 2 1 the library

familiarizing students with the library. anecdotal statements from students who viewed the tour during its creation noted the desire that such a tour had been available when they began college and further commented on the assistance that the tour will provide new students. a limitation of this study is the low participation, with no participation from students from some of the groups that other studies have shown may have higher levels of library anxiety (e.g., new students, international students). however, given the indications of positive effects of the virtual tour from our study results and anecdotal statements, we are encouraged that this tool that will assist our students in reducing library anxiety, with the result that they will visit and use the information technology and libraries march 2020 using augmented and virtual reality in information literacy instruction | sample 24 library more often to their benefit. again, although participation was low, these results have also encouraged oru librarians to seek other ways to include avmr and other innovative technologies in our instruction, outreach, and services. the 360 virtual tour of the library is undergoing updates and additions to provide students with disabilities information on access points and accessible restrooms. other projects underway include incorporating avmr in il sessions, the addition of a digital sandbox with various technologies and equipment including a vr station, and the addition of vr equipment in our designated faculty research room for use by university faculty to learn and teach students how to use avmr technologies. the response from students and faculty to these new services has been enthusiastic and encouraging that the oru library is positively influencing and supporting the academic work of oru faculty and students. recommended reading varnum, kenneth j. beyond reality: augmented, virtual, and mixed reality in the library. chicago: ala editions, 2019.

with its uses for teaching presently being investigated in a variety of educational settings. however, one area where the effect of this technology on students has not been examined in detail is as tool for new student orientation in colleges and universities. this study investigates this effect using an experimental methodology and the population of new master of library science (mls) students entering a library and information science (lis) program. the results indicate that students who received a vr orientation expressed more optimistic views about the technology, saw greater improvement in scores on an assessment of knowledge about their program and chosen profession, and saw a small decrease in program anxiety compared to those who received the same information as standard textand-links. the majority of students also indicated a willingness to use vr technology for learning for long periods of time (25 minutes or more). the researchers concluded that vr may be a useful tool for increasing student engagement, as described by game engagement theory. literature review computer-assisted instruction (cai) has, for many years, been considered an effective method of instructional delivery that improves student engagement and outcomes.1 new technologies, such as the learning management system (lms), online video, laptops and tablets, word processors, spreadsheets, and presentation platforms, have all significantly altered how knowledge is transferred and measured in students. when adopted by instructors, these technologies can improve the quality of student learning, work, and their evaluation of this work. empirical research has shown that learning technologies do indeed contribute to better learning than a lecture alone.2 positive reaction to the adoption of new learning technologies among student populations has been shown across all grade levels, from pre-k through postgraduate education.3 research in the fields of instructional design technology (idt) and information science (is) have shown that the novelty of new learning technology provides short-term improvement in outcomes.4 this supports the broader hypothesis that engagement increases retention of knowledge. these findings would suggest that, at least in the short term, instructors could anticipate improvement in knowledge retention through the use of a new technology like virtual mailto:svalenti@emporia.edu mailto:blund2@g.emporia.edu mailto:twang2@emporia.edu information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 2 reality. when used in sustained instructional efforts, many learning technologies show som e promise for improving the attainment of learning outcomes.5 this is why interest in learning technology has grown so significantly in the past two decades and the job outlook for instructional designers is increasing faster than the national average. 6 a large proportion of instructional technologies are not truly “adopted” by instructors, but rather used only in one-off sessions and then discarded.7 there seem to be some common factors among those technologies that are adopted and used regularly by instructors: 1. practicality, or the amount of work the new technology requires versus the perceived value of said technology; 2. affordability, or the cost of a new technology versus the perceived value of said technology; and 3. stability, or the likelihood of the product to be continuously supported and updated by its manufacturer (e.g., a product like microsoft office has a higher likelihood of ongoing maintenance).8 as noted by lund and scribner, only recently, with the introduction of free vr development programs and inexpensive viewers/headsets like google cardboard, has vr fit this criteria. 9 it is finally practical to use vr as a learning tool for classrooms with large numbers of students. “virtual reality is the computer-created counterpart to actual reality. through a video headset, computer programs present a visual world that can, pixel-perfectly, replicate the real world—or show a completely unreal one.”10 virtual reality is distinct from augmented reality, which augments a real-world, real-time image (e.g., viewed through a camera on a mobile device) with computer-generated information, such as images, text, videos, animation, and sound.11 the focus of the present study is virtual reality only, not related augmented (or mixed) reality technology. an important contribution to the study of virtual reality in library and information science (lis) is varnum’s beyond reality.12 this short introductory book covers both theoretical and practical considerations for the use of virtual, augmented, and mixed reality in a variety of library contexts. while the book describes how vr can be utilized in a variety of library education (for non-lis majors) contexts, it does not include an example of how virtual reality may be used for library school education. it also does not investigate in significant detail the use of virtual reality for a virtual orientation to an academic program. these are the gaps in which the following study attempts to address. the present study may be viewed through the framework game engagement theory, as described by whitton.13 game engagement theory suggests that five major learning engagement factors exist and that using gaming activities may improve how well learning activities address these factors. these factors include: • challenge, motivation to undertake activity; control, the level of choice; • immersion, extent to which an individual is absorbed into activity; • interest, an individual’s interest in the subject matter; and • purpose, the perceived value of the outcome of the activity. information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 3 it has been suggested by several researchers, including dede, that immersive experiences like vr touch on similar factors of engagement.14 emporia state university’s school of library and information management the setting for this study is emporia (ks) state university’s school of library and information management (esu slim). esu slim is the oldest library school west of the mississippi river, founded in 1902. compared to other lis education programs, esu slim is unique in that it offers a hybrid course delivery format. the six core courses in the mlis degree program are online with two in-person-class weekends for each class. each class weekend is eleven hours: from 6 to 9 p.m. friday and 9 a.m. to 5 p.m. saturday at one of nine distance education locations scattered throughout the western half of the united states. due to this course delivery format, the student population of esu slim may skew slightly older and have more individuals who are employed fulltime in relation to residential master’s programs. esu slim uses a cohort system, with a new group of students beginning annually at each of the eight distance locations as well as the main emporia, kansas campus. before each new cohort begins its first course, a one-day, in-person student orientation is offered on the campus in which the cohort will attend classes. the purpose of this experimental study is to examine how well vr technology can support or satisfy the role of the in-person student orientation by emulating the experience/information students receive during this informational session. methods this study was designed with a pre-test/post-test experimental design. depending on the state in which the students reside, they were assigned either to the experimental or control group . the experimental group received a cardboard vr headset (similar to google cardboard) and a set of instructions on how to use them. they were instructed to utilize this headset to view an interactive experience that introduced elements of library service and library education as a form of new student orientation. students in the control group received a set of links that contained the same information as the vr experience, but in a more static (non-immersive or interactive) setting. participants for this study were library school students from four states: south dakota, idaho, nevada, and oregon. these students were all enrolled in a mixed-delivery program in lis. for each core course in the program, students attend two intensive, in-person, weekend class sessions. the rest of the course content is delivered via a learning management system. for this study, the researchers were particularly interested in understanding the role of vr orientation for distance education students, as these students do not have access to the physical university campus and thus miss out on information that in-person interaction with faculty and the library environment might provide. this also seemed like a worthwhile population to study given that a large portion of lis programs have adopted the distance education (online or mixed-delivery) format. in march 2019, a sample of this population was asked to complete a short survey to indicate their interest in virtual reality for new student orientation and the extent to which acquiring information via this medium may relieve their anxiety and increase their success in the program. sixty-one percent of students indicated at least some elevated level of anxiety about their first mls information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 4 course, while 55 percent agreed that knowing more about the program’s faculty and course structure and purpose would decrease that anxiety. students were also asked to indicate the most pressing information needs they have about the program. these needs are displayed in table 1 below. this information was used to guide the design of the vr content for this study. table 1. information needs expressed by new mls students information need number of respondents (out of 55) information about esu’s curriculum 50 what courses professors normally teach 42

information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 5 figure 1. new mls students reception to using vr as an orientation tool based on the largely positive response towards using vr for new student orientation, the researchers progressed to the experimental phase of the study. a vr experience was developed using veer vr (veer.tv), a completely free and intuitive vr-creation platform. within this platform, creators are able to upload images that were captured using a 360-degree vr camera (we used a samsung gear 360 camera) and drag-and-drop interactive elements, including text boxes, videos, audio, and transitions to new images. thus, it was possible to create a vr experience within the setting of an academic library where users could navigate throughout the building and virtually meet faculty and learn about fundamental concepts in librarianship. for this phase of the study a set of research questions were defined, hypothesis created, and independent and dependent variables identified: research questions 1. research question 1: will vr improve students’ knowledge of topics related to their library school and basic library topics, relative to those without a vr experience? 2. research question 2: will vr reduce students’ anxiety about their library program, relative to those without a vr experience? 3. research question 3: will students’ perceptions towards the usefulness of vr be significantly different based on whether or not they utilized the vr experience? 0 2 4 6 8 10 12 14 16 18

of vr. experimental phase the experimental phase of the study was conducted in august 2019. twenty-nine students agreed to participate in this study. the age and gender characteristics of this population are as follows: fourteen under age 35, eleven age 35–44, four age 45+; nine male, seventeen female, and three fluid or transgender. thirty-three percent of the students who agreed to participate were in the control group, while 67 percent were in the experimental group. all participants in the study received a free vr headset, which was theirs to keep. funding for these vr headsets was provided by a generous grant from a benefactor at the researchers ’ university. participants in the control group were encouraged to use the vr headset after they had completed their participation in the study. both groups received instructions with their viewer that instructed them to complete a pre-test survey, embedded within a module of their learning management system account. following the pre-test, the experimental group was instructed to use the vr experience created by the researchers to learn about their library school, its faculty, and the library concepts. the control group was instructed to use links provided in the module to experience the same content, but without the vr experience. following the experience, both groups were instructed to complete a post-test survey in the module, as well as a follow-up survey that asked questions about how long they interacted with the content, how the experience affected their program anxiety, and additional comments. once the data was collected for all participants, the researchers’ conducted a series of analyses on the data, including an analysis of covariance (ancova) for post-test scores among the control and experimental groups, and ancova for program anxiety following the experimental treatment. 15 results figure 2 displays the amount of time participants in the experimental group spent using the vr experience. nearly 60 percent of participants spent more than 25 minutes using the virtual reality experience. this finding may seem remarkable, given the average attention span of students is generally no more than a handful of minutes, but aligns with that of geri, winer, and zaks, who found that engagement with interactive video lengthens the attention span of users, and supports the premise of engagement theory as discussed in the literature review.16 only 10 percent of individuals assigned to the experimental group decided not to use the headset. additionally, about information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 7 one-third of participants in both the experimental and control groups indicated that they used the vr headset to view other content after they completed the study. figure 2. amount of time experimental group participants spent in vr experience in table 2, responses for likert question about the participants’ post-test perspectives of vr are shown. participants in the vr group generally had more favorable perspectives on their experience than participants in the control group. participants in the control group, however, were a bit more optimistic on the idea that vr has promising uses for education and librarianship (though both groups expressed optimistic perspectives on these questions). there was some indication that participants would be willing to use vr for student orientation again, as both groups responded favorably to the idea that vr orientation information is appropriate and negatively to the idea that it would be better to get information from other sources. tables 3 and 4 display the ancova for pre-test/post-test score change among groups and the change in anxiety among the groups, respectively. post-test scores for the experimental (17.23 correct out of 20 questions, or 86 percent) and control group (17.38/20, or 87 percent) were virtually identical; however the pre-test scores differed (experimental group, 72 percent, scored worse on the pre-test than control group, 78 percent), so the change in scores was actually greater for the experimental group. as shown in table 3, though, this difference in score change was not found to be statistically significant, f (1, 20) = .641 p = .4, r = .01. that is, no significant difference was found as to whether vr improves scores compared to links. it can be concluded, however, that information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 8 the links and vr together did improve scores from the pre-test to the post-test, with ancova values of f (1, 20) = 7.6, p < .01, r = .47. table 2. post-test perspectives of vr for

though the vr group generally reported less anxiety on a five-point likert scale following the experiment than the control group (both groups showed some reduction), this difference was not statistically significant at p<.05 (though it was significant at p<.1). it is worth noting that few students indicated prior experience with vr before this study, so it may have simply been the unfamiliar technology that resulted in anxiety not dropping as far as anticipated, not the nature of the content. at the same time, it is worth noting, as bawden and robinson did, that information overload, which could certainly be the product of immersive vr orientations, is connected to information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 9 information anxiety.17 thus, it may be better, in the design of vr orientations, to keep the amount of new information at a minimum, only introducing broad concepts and allowing more freedom and flexibility for the user. table 4. ancova for anxiety following the orientation experience sum of squares df mean square f sig. between groups 3.219 1 3.219 3.44 9 .07 9 within groups 17.733 19 .933 total 20.952 20 discussion participants in this study expressed willingness to use vr for extended periods of time (over 25 minutes) and demonstrated strong levels of engagement. based on this finding, it seems possible that a well-designed vr orientation could be a suitable substitute for the in-person orientation for distance students. this is a significant finding, given that the majority of existing research on orientation for distance education students focuses on the design of online course modules or video streaming for orientation, which are not nearly as immersive and dynamic as physical presence in the environment.18 vr much more closely emulates physical presence than noninteractive/immersive videos and text. those among the participants who were in the experimental (vr) group expressed more favorable perspectives towards the technology. this suggests that experience with the technology increases comfort and interest in the technology. this aligns with the findings of theung, mei-ling, liu, cheok, among others, who found that use of vr were more likely to accept the technology after usage.19 additionally, stated interest in using vr for other purposes, including one-third of participants who have already utilized the technology to explore other apps suggested by the researchers. the findings of this study align with game engagement theory in several of its key aspects. vr is shown to have garnered the interest of the students who participated in the study, as indicated in table 2, aligning with the aspect of interest. they could see the purpose of the experience and were able to take control of the experience to ensure that they interacted with necessary information to satisfy this purpose. this is opposed to the control group, which had to follow links and read text in a sequential order with little control or creativity involved. accordingly, greater improvement in scores was observed for the experimental group. even though the improvement was not statistically significant, this could likely be explained by the relatively small sample size. with a larger number of participants, the statistical strength of the differences between the two study groups may have been more pronounced. this is one limitation of the present study. in addition to a small participant group, several other limitations exist with this study. participants came from only a small sample of states, all in the western half of the united states. a less homogeneous sample may have produced more robust results. some vr headsets arrived late due to delays in distributing them, giving the students less opportunity to review the content than information technology and libraries june 2020 virtual reality as a tool for student orientation | valenti, lund, and wang 10 they otherwise may have had. finally, the researchers were not able to easily troubleshoot problems with accessing the vr experience for distance students. while the best was done to help all participants figure out how to use the technology, several students opted to discontinue participation when the technology gave them trouble. this also led to a smaller study sample population than initially anticipated. conclusion the findings of this study may have several important implications for library professionals who are considering using vr technology for library orientations or instruction. this study found vr to have a positive effect on students’ interest and to slightly increase scores and reduce anxiety among them. while there is no indication from this study whether vr would produce positive effects over a sustained period of time (e.g., every class session over the course of a semester), in limited usage it appears to at least draw students’ attention more so than the traditional online teaching options like static text and links. the same vr experience developed to introduce students to basic concepts within the librarianship/the library could be used for undergraduate and graduate students in all majors during library orientation sessions. this may make the library a more memorable component of students’ early university experiences, as opposed to lecture information that students are likely to easily forget. library professionals may consider these factors when deciding whether to opt for the more traditional methods of instruction/orientation or experimenting with a more innovative method of teaching like virtual reality. endnotes 1 jennifer j. vogel et al., “using virtual reality with and

and information management methods research questions hypothesis variables experimental phase results discussion conclusion endnotes this paper discusses some of the problems associated with search and digital-rights management in the emerging age of interconnectivity. an open-source system called context driven topologies (cdt) is proposed to create one global context of geography, knowledge domains, and internet addresses, using centralized spatial databases, geometry, and maps. the same concept can be described by different words, the same image can be interpreted a thousand ways by every viewer, but mathematics is a set of rules to ensure that certain relationships or sequences will be precisely regenerated. therefore, unlike most of today’s digital records, cdts are based on mathematics first, images second, words last. the aim is to permanently link the highest quality events, artifacts, ideas, and information into one record documenting the quickest paths to the most relevant information for specific data, users, and tasks. a model demonstration project using cdt to organize, search, and place information in new contexts while protecting the authors’ intent is also introduced. ■ statement of the problem human history is composed of original events, artifacts, ideas, and information translated into records that are subject to deciphering and interpretation by future generations (figure 1). it’s like putting together a puzzle, except that each person assembling bits and pieces of the same information may end up with a different picture. we are at a turning point in the history of humanity’s collective knowledge and expertise. we need more precise ways to structure questions and more interactive ways to interpret the results. today, there is nearly unlimited access to online knowledge collections, information services, and research or educational networks to preserve and interpret records in more efficient and creative ways.1 there is no reason digital archiving and dissemination techniques could not also be used to streamline redundancies between collections, build cross-references more methodically.2 content should be presented and techniques utilized according to orderly specifications. this will help to document work more responsibly, making shared records more correct, interesting, and complete. the open-source system proposed, context driven topologies (cdt), packs and unpacks ideas and information in themes similar to museum exhibitions using specifications created by each author and network. data layers are formed by registering unique combinations of geography, knowledge domains, and internet addresses to create multidimensional shapes showing where data originate, where they belong, and how they relate to similar information over time. the topologies can be manipulated to consolidate and compare multiple sources to identify the most reliable source, block out repetitious or irrelevant background information, and broadcast precise combinations of ideas and information to and from particular places. “places,” in this sense, means geographic region and cultural background, knowledge domain and education level, and all of their corresponding online resources. modern information must be searchable on multiple and simultaneous levels.3 today’s searches occur for a number of reasons that did not exist when most current collections, repositories, and publications were created. digital records have the potential to reach far broader audiences than original events, artifacts, and ideas. therefore, digitized items and the acts of publishing and referencing over networks could theoretically serve a longer-term and more expanded purpose than most individual collections, repositories, or publications are designed to serve. there is no shortage of interesting work to look at. we live in a complex world that is just recently being digitized, mapped, analyzed, and broadcast over the internet in fine detail and compelling overall relationships. many deborah l. macpherson (debmacp@gmail.com) is projects director, accuracy&aesthetics (www.accuracyandaesthetics.com) in vienna, virginia. deborah l. macpherson digitizing the non-digital: creating a global context for events, artifacts, ideas, and information digitizing the non-digital | macpherson 95 figure 1. 50 word word-search-puzzle (courtesy of kevin lightner) 96 information technology and libraries | june 2006 of these relationships require mathematics, images, and maps to explain them. we need more than keywords to explore and reference all that has been documented, but we have formed the habit of using keywords and machine-based classification schemes. the entire digital world is in a mire of conflicting priorities, funding opportunities, and intellectual quests toward the future. to advance humanity’s collective curiosity and knowledge, and to coordinate similar efforts across disciplines and cultures, we need one form of record keeping. one global context to show: 1. where ideas and information begin; 2. if the original is non-digital (e.g., an artifact or real world event), and if so, the location where the artifact resides or the time and place of the event; and 3. a marking system to keep track of the ways information has been exchanged, reinterpreted, and reused to create a more comprehensive and simplified guide to humanity’s collective knowledge and expertise. digitizing the non-digital is a concept to address three issues: ■ tools to assemble the bigger pictures needed to document the best paths to the most relevant information in sets rather than retrieving results item by item; ■ placeholders for information that has not been digitized or was never recorded; and ■ distribution to and from specific places according to the ways it is used, the kind of information it is, and the types of people who are able to understand it. there is currently little distinction between all data that have been collected or exist, versus the data and techniques selected to draw conclusions. there are no tools to differentiate between information under rigorous discussion by a discipline or culture versus random bits and pieces. there is a need to develop the equivalent of interpretive exhibits to instruct and inspire the general public. there is currently no way to herd information into crowded areas to be consolidated, compressed, and prioritized by its relationship to similar ideas and information. citation patterns are able to show connections or structure-related information.4 however, they currently do not show whether the reference is for or against the other work. there are very few big pictures.5 there is no way to trace where an idea has led over time. the global context proposed is not like the ancient library of alexandria or large-scale contemporary initiatives. the envisioned process looks beyond the quest to digitize or publish every available event, artifact, and idea. it is not about each item itself. it is being able to make sense of the ways the same information can be viewed in different contexts, and being able to construct a reliable process to search and document the results. having bigger pictures will allow researchers, curators, and others to see what is missing or decide which archival works should be converted into digital form. we do not have the time, resources, or reasons to digitize every item in every collection. the aim is to gradually identify what the most telling examples are in different areas so someone new to an event, artifact, idea, or information can see it in various contexts and automatically be shown the most compelling or instructive sequences first (figure 2). a coordinated effort to overlap and see all archives and publications by ranking accuracy and appeal to the public in relationship to all knowledge will make it possible for entirely new lines of inquiry to be established. it will help researchers coordinate work across disciplines. an example of this principle today is the international virtual observatory alliance (ivoa).6 ivoa is a coordinated effort by astronomers worldwide to document our universe more efficiently by systematizing their records; showing where they originate; indicating how they were collected; meeting their rigorous mathematical figure 2. photomosaic ® thousands of miniature images of the civil war combine to make one large portrait. (courtesy of robert silvers) article title | author 97digitizing the non-digital | macpherson 97 standards; and deciding themselves how and where their records belong in relationship to each other, and which ones are most important. only astronomers are qualified to do this. the same is true in any area of humanity’s specialized knowledge and expertise. the most difficult aspect of creating a global context is accommodating and expressing each area in its unique way as created from within, while still being able to get the most descriptive examples from all areas to fit together in a sensible and appealing overview. until digital archives and publications can be deeply searched on a global level using simpler tools and predetermined pathways accessible by anyone, two researchers in different geographic or academic areas may be investigating the same topic from different points of view and will not know it. there is no way to be led to the best internet resources. today, as so much information surrounds us, it is hard to believe that common lines of inquiry could be discovered by accident. context of the place, time, idea, or education level should be able to drive internet topologies to the most appropriate online resources. constructing a reliable and beautiful digital history of all events—both natural and man-made—artifacts, ideas, and information means contributing to and combining a wide range of knowledge, expertise, networks, archives, and tools. mapping digital knowledge to historical knowledge means arguing about and perfecting an entirely new set of checks and balances. historical and digital knowledge are different. historical knowledge is fluid, continuous, and held by traditionally separated cultures and disciplines. digital knowledge goes everywhere that can be marked and traced by the times and places it was created, captured, and distributed. trying to visualize what is happening and relating it to working practices and the types of information that came before it is not like tracing the history of the human race back to adam and eve or the universe back to the big bang, where substantial guesswork beyond our memory or experience is involved. the entire conversion into the networked age is happening before our eyes in less than one generation without the benefit of reflection, careful review, and storytelling. we’re collecting everything indiscriminately over and over again while all datasets are rapidly expanding. we need to step back, slow down, and acknowledge that many current digitization and publication methods do not consistently generate reflective or reviewed results that are able to tell a story. we do not currently have one shared map, context, mathematical record, language, or set of symbols to interpret from different points of view for a variety of purposes over time. we do not currently mark the original versus subsequent interpretations of the same information as an integral component of most digital records. there is no financial support for one single shared storage space to preserve only the highest-resolution, most agreed-upon versions because we may never be able to agree on what they are. therefore, there is also not one system that can be fine-tuned to discover research and results that may be accidentally overlapping. instead, unusual approaches get watered down by constrained words designed to fit metadata requirements developed by archivists and engineers rather than the original authors. links get broken, web sites are no longer maintained, trends change. there are currently very few feasible ways to pick up on a line of inquiry previously initiated by others without sorting through and regenerating the same information again.7 a simplified version of the work needs to be preserved on the network, able to be referenced by others even if they are far away, live in a different time, or are more or less advanced in their ways of thinking. if digital information is reliable, someone in a remote place or in the future should not need to collect the same information again or unintentionally retrieve out-of-date or duplicate results. searches in the public domain should not be boring. they should be as easy to click through as tv channels, with more directions to go and better content. all searchers should not have to start at the top like everyone else on the first page of google, citeseer, or arxiv with a blank white space and a box to enter key words. investigators should be able to outline the facts they know, dial in measurements, specify relationships, and generally be able to use their own knowledge and expertise to isolate and extract entire ideas over broad spectrums or select only relevant portions of archives and publications to reintegrate into larger bodies of work for further discussion. digital objects are able to depict more than the unaided eye can see. an example is the evaluation of the center of mass of michelangelo’s david performed for david’s restoration by the visual computing lab based on a 3d model of the statue built by stanford university (figure 3).8 the digital david does not have mass. the original david is a beautiful object sculpted of a known and predictable material. the model makes it possible to test restoration techniques without permanent damage in ways no one would dare attempt on the irreplaceable original without first knowing more. the documentation process is an enhanced original that should be permanently bound to the digital history of the original sculpture. the evaluation method could be applied to other objects, but this model belongs with this object and this type of research. a global context built upon a solid, mathematically linked foundation would mean this conscientious work would not be lost or need to be repeated. digital records are not being used nearly to their full potential. so many influences on humanity’s intellectual evolution could be examined as history takes shape over 98 information technology and libraries | june 2006 time. concurrent and conflicting interpretations can take on more meaning than the original by itself. for example, how could the internet and legal citations be used to map the subsequent interpretations of the u.s. constitution from the time, place, and reasons where it was written to every supreme court case and related citation since the original context? what would this map look like (figure 4)? the impact that these four pages of ink on paper have had to the united states and the entire world cannot currently be examined in one volume to see where the most contentious and useful passages are. similar dynamics in wikipedia are shown in history flow by martin wattenberg at ibm research.9 what if techniques developed in one field could be applied to content from another area? for example, what if computer models created to track storms and hurricanes could be used to arrange and watch the evolution and real world impact of all the documents and actions associated with a war? being able to see how originals evolve in their interpretation and impact on society over time is practical because not all records are worth keeping. even worse, mundane or meaningless events, artifacts, ideas, or information may seem more important than they actually were if they are not translated into digital form or distributed in the right way.10 the task today is to make the most advanced ways of thinking and working more approachable and appealing to someone new, which is everyone outside a particular discipline or culture, while traversing a map of humanity’s collective knowledge and expertise. because shared memories of this magnitude would be so far-reaching and complex, the record itself needs to be able to show every user how to use it. every unique purpose for looking around, publishing, or referencing work, and adding to or taking away from a collaborative global context should be geared toward improvement and simplification. while millions and millions of people are accessing enormous numbers of files and collections, some paths are better than others. in order to sort and choose the best parts of vast collections, documenting everyone going in and out of various semantic places can ultimately identify the best paths to information everyone understands. what if someone who does not care at all about paintings makes an inquiry—which ten should they be shown to get them interested? there is also the issue of gearing the internet to provide more efficient pathways to widely accessed preapproved and curated information. every mouse click could accumulate to document the most reliable pathways in and out of shared information spaces to generate an assortment of scenarios for looking at the same information in different ways (figure 5).11 we think there is far too much information to consolidate into one big picture, that our ideas and methods are too incompatible to coexist comfortably in one space, but perhaps this is not really the case. perhaps we can understand what is happening more clearly by working backwards. ■ proposed solution and design for a running prototype even though many networks are in place and countless computers have been manufactured, technology advances rapidly. there are very few reasons to repair obsolete equipment or maintain outdated web resources. therefore, why not go back to the drawing board on all of it? we may have completely new computers and networks within ten years, anyway. a record-keeping and referencing system this ambitious needs to incorporate every type of record, classification scheme, symbol, style, and quirk. when visiting a new place outside your comfort zone, it needs to be obvious what the best local techniques are to filter and understand the results. people new to an area need to have the option of using tools they can invent or already know. figure 3. david’s center of mass (courtesy of the visual computing lab and stanford university) article title | author 99digitizing the non-digital | macpherson 99 the visualization of cdt’s model demonstration project will bring together research scientists, artists, integrators, and institutions to develop a running prototype. the purpose is to establish and record a series of planned and spontaneous situations in different parts of the world across a range of disciplines and existing networks so that these situations can be mapped. the project will be a group of people thinking together to confront the roadblocks in assembling incompatible ideas and information into one context. the group will collaborate in larger and smaller groups in roughly three-month intervals as participants continue with their existing work. the development of this system has to be dynamic, changing piece by piece both from the bottom up and the top down while everyone’s regular work continues. therefore, the system will be geared toward sample sets of active work products, rather than the record-keeping system by itself. the current objective is to establish a network of ten art museums, ten scientific research institutes, and ten new media/new technology efforts in ten cities that speak different natural languages (for example: english, german, french, italian, hindi, mandarin, ga [belonging to the cluster of kwa languages in ghana], uzbek, spanish, and arabic). the overall intent is to use mathematics, art, and individual ways of knowing to develop a series of professional sketches to serve as shortcuts between languages and key words in the search process. the first step is to map the background of each of the project participants’ previous work by time, location, and discipline. the database will include scientific visualizations, art objects, performances, algorithms, mathematical formulae, musical recordings, and many other forms of creative and scholarly expression. the next steps will be to hold a series of interactive workshops. at the first workshop, the research scientists will explain the mathematics and images they use in their work. two sets of artists will isolate the aesthetics to render their own map through the scientists’ ideas. two traveling exhibits will be created, one to be experienced in person, the other to be presented through a new media and online exhibit. both will be tracked physically and conceptually using cdt. the results will be generated and interpreted using gis, matlab, photoshop, and flow visualization software. for more information, please contact the author. a survey of individual and institutional requirements will be undertaken to define practical ways to move and organize ideas and information into a unified sample map of previously unrelated content and techniques. for example, at one institute, perhaps only two participants and four local professors will understand what that part of the map is showing. another part may only have meaning to one artist. a unified map for everyone, with built-in copyright protection for the participating artists, scientists, and institutions, will be presented to nonspecialist general publics around the world for feedback and further change within specified limits. the participating publics will be people interested in contemporary art, cutting-edge scientific research, new media, and events where all three communities can interact. each part of the prototype will be able to be examined in groups to compare and contrast different elements against different backgrounds. some arrangements will be assisted by the computer and network. the project will map everything with which each event, idea, and artifact has ever been associated in scale, proportion, and relative placement in the record overall. for example, if the records in question are paintings, any group could figure 5. thick and thin (courtesy of the artist john simon) figure 4. the constitution of the united states (courtesy of the u.s. national archives and records administration [nara]) 100 information technology and libraries | june 2006 be gathered together into the same reference window without copying the images. the assembly window has a built-in scale for the items it is showing, so they will be displayed in the correct proportion to each other. the system binds images of physical objects with their dimensions and the times and places they were created while this information is known—so a user does not ever have to guess later when looking back at any part of the record. any group of paintings can be automatically arranged chronologically, by size, culture, or any number of comparisons and curatorial issues. a sample sequence is: 1. a zoomed-in map showing a group of paintings in an exhibit. each painting links to its history. 2. within the map of all paintings shown in an intricate collage. 3. inside the map of all human endeavor shown as an appealing landscape. higher levels can then be used to reorganize a theme, for example, “only germany 2005 to 2007,” and drilling back down to generate other exhibitions. this would lead to other paintings and other curators’ conclusions, which would provide a more complete representation of each painting, exhibition, museum, curator, culture, and era. when the records in question are scientific visualizations, problems of presenting unrelated files together are more complex. the records may not share a common scale or system of reference. it may only be possible to place mathematical constructs in contexts based on where they originate geographically and by knowledge domain. an important part of the work will be determining the best contexts by which to introduce ideas or information to untrained viewers and devising methods to start deeper in the records using mathematical, cultural, or other prior knowledge and preferences. the same concept can be described by different words, the same image can be interpreted a thousand ways by every viewer, but mathematics is a set of rules to ensure that certain relationships or sequences will be precisely regenerated. therefore, unlike most of today’s digital records, cdts are based on mathematics first, images second, words last. ideas and information will be encoded to persist over specified periods of time. better examples will find higher placement by connecting to more background information and showing stronger relationships to larger numbers of open questions. cycles will be implemented to return to the same idea later and remove information that is never referenced or has not changed the course of the record’s flow. out-of-date, irrelevant, or rarely used information has to either be compressed or be thrown away, a new type of identity and a process to assemble and eliminate information will be created in thirty prototype forms showing the intertwined history of the events, artifacts, ideas, and information generated by the project and all it branches out to when connecting back to the publications, exhibits, ideas, artifacts, and other information generated by the participating individuals and institutions. the cdt model will relate and join tables to display all the different forms together in one map. each piece of information and the patterned space around it will be documented a special way to generate drawings leading back to originals reliably structured to transfer to other computers and networks. they will transfer without ambiguity because the transactions and paths to the internet addresses are based on mathematical relationships that can be checked. each contributor has the first opportunity to place his or her ideas in context and define the limits of how their originals can be referenced, changed, and presented. at the end of the project, the set will be closed so that it can be cleaned of information that was only temporary, placeholders can be examined, and the entire model can be manipulated as one whole. for more information, please see www.contextdriventopologies.org the more specified a single piece or set of information, the easier it will be to define its history and place it in context. each unique placement and priority assigned by each individual or institution may not agree with the priorities and placements envisioned by others, but sooner or later, there will begin to be correspondence and everyone will be looking very generally at the same emerging map. ■ conclusions there will be innumerable contexts to create, discover, and remark upon in the future by creating a shared pace of curiosity and knowledge acquisition. a global context could be used to extrapolate new knowledge from trends that occur over longer periods of time in more places than we currently share or document. as the envisioned system is fine-tuned, it will become an ideal place to test an idea that is only partially complete to see where the idea fits or to determine if it has already been done. the results could be immediately applied to improve education. in today’s frantic information overload, we should not forget that digital information—and even cold, hard, raw data—is more than ones and zeros. they represent peoples’ work, their fingerprints; people are attached to their data. one wishes networks of computers could understand one’s ideas and work, but we only show them the boring parts. the proposed system will capture beauty so computers can help to find where it is hidden inside all the repositories, publications, and collections through which no person has the time to sort. the system will allow article title | author 101digitizing the non-digital | macpherson 101 users to specify how they think their information relates to the rest of the world so their intended context can be traced in the future. one hopes that using networks and computers to compare ideas and works on larger levels will restore craftsmanship and attention spans to make users want to spend more time with better information. a shared visual language driven by mathematical relationships that can be checked will allow future historians to see where records simply will not harmonize. users will be able to analyze why different ways of looking can shape and divide knowledge and history as it changes. visiting online archives and publications will change. developing processes to pre-organize searches and results for public viewing can change now by creating a system for curators and others to develop sets of information, rather than publishing individual items on their web sites. library facilities can change, and research rooms can become multimedia centers. networks can broadcast content and techniques in one package. there is not one clearly defined reason why being able to see these kinds of overviews or make these types of comparisons can be useful. the internet is a worldwide invention being constructed for a variety of purposes. a perfectly legitimate reason to capture the history of transactions across it in a simple form is just to see what might happen with the objective of increasing our understanding and respect for each other. the most important reason for establishing a global context is to allow users to transfer and update complex histories, thoughts, images, studies, visualizations, drawings, flow diagrams, sequences, transformations, cultural objects, stories, expressions, and purely mathematical or dynamic relationships without depending on constrained keywords or illegible codes that do not describe this information as well as the information can describe itself. all cultures and disciplines would be able to construct their parts of the record precisely the way they prefer. we would finally be able to use computers to show why and how we think information is related—a huge leap forward in the world of digital record keeping. references and notes 1. citeseer, 2005,

information technology and libraries | december 2018 27 sam searle (samantha.searle@griffith.edu.au) is manager, library technology services, griffith university, brisbane, australia. abstract this case study describes how librarians and enterprise architects at an australian university worked together to document key components of the library’s “as-is” enterprise architecture (ea). the article covers the rationale for conducting this activity, how work was scoped, the processes used, and the outputs delivered. the author discusses the short-term benefits of undertaking this work, with practical examples of how outputs from this process are being used to better plan future library system replacements, upgrades, and enhancements. longer-term benefits may also accrue in the future as the results of this architecture work inform the library’s it planning and strategic procurement. this article has implications for practice for library technology specialists as it validates views from other practitioners on the benefits for libraries in adopting enterprise architecture methods and for librarians in working alongside enterprise architects within their organizations. introduction griffith university is a large comprehensive university with multiple campuses located across the south east queensland region in australia. library and information technology operations are highly converged and from 1989–2017 were offered within a single division of information services. scalable, sustainable, and cost-effective it is seen as a key strategic enabler of the university’s core business in education and research. “information management and integration” and “foundation technology” are two of four key areas outlined in the griffith digital strategy 2020, which highlights enterprise-wide decision-making and proactive moves to take advantage of as-a-service models for delivering applications.1 from late 2016 through to early 2018, library and learning services (“the library”) and it architecture and strategy (itas) worked iteratively to document key components of the library’s “as-is” enterprise architecture (ea). around fifty staff members have participated in the process at different points. the process has been very positive for all involved and has led to a number of benefits for the library in terms of improved planning, decision-making, and strategic communication. as manager, library technology services, the author was well placed to act as a participant-asobserver with the objective of sharing these experiences with other library practitioners. the author actively participated in the processes described here and has been able to informally discuss the benefits of this work with the architects and some of the library staff members who were most involved. mailto:samantha.searle@griffith.edu.au benefits of enterprise architecture for library technology management | searle 28 https://doi.org/10.6017/ital.v37i4.10437 literature review enterprise architecture (ea) emerged over twenty years ago and is now a well-established it discipline. like other disciplines such as project management and change management, there are a number of best practice frameworks in common use, including the open group architecture framework (togaf).2 a global federation of member professional associations has been in place since 2011, with aims including the formalization of standards and promotion of the value of ea.3 educational qualifications, certifications, and professional development pathways for enterprise architects are available within universities and the private training sector. according to the international higher education technology association educause, ea is relatively new within universities but is growing in importance. as a set of practices, “ea provides an overarching strategic and design perspective on it activities, clarifying how systems, services, and data flows work together in support of business processes and institutional mission.”4 yet despite this growing interest in our parent organizations, individual academic libraries applying ea principles and methods are notably absent from the scholarly literature and library practitioner information sharing channels. the fullest account to date of the experience and impacts of enterprise architecture practice in a library context is a case study from the canada institute for scientific and technical information (cisti). at the time of the case study’s writing in 2008, cisti was already well underway in its adoption of ea methods in an effort to address the challenges of “legacy, isolated, duplicated, and ineffective information systems” and to “reduce complexity, to encourage and enable collaborations, and, finally, to rein in the beast of technology.”5 the author of this case study concludes that while getting started in ea was complex and resource-intensive, this was more than justified at cisti by the improvements in technology capability, strategic planning, and services to library users. broader whole-of-government agendas are a driver for ea adoption in non-university research libraries. the national library of finland’s ea efforts were guided by a national information society policy and the ea architecture design method for finnish government. 6 a 2009 review of the it infrastructure at the u.s. library of congress (lc) argued lc was lagging behind other federal agencies in adoption of government-recommended ea frameworks. the impact of this included: inadequate linking of it to the lc mission; potential system interoperability problems; difficulties assessing and managing the impact of changes; poor management of it security; and technical risk due to non-adherence to industry standards and lack of future planning.7 a followup review in 2015 noted that lc had since developed an architecture, but that it had still fallen short by not gathering data from management and validating the work with stakeholders. 8 there is little discussion in the literature about the ea process as a collaborative effort. in their 2016 discussion of emerging roles for librarians, parker and mckay proposed ea as a new area for librarians themselves to consider moving into, rather than as a source of productive partnerships.9 they argued that there are many similarities in the skillsets and practices of enterprise architects and information professionals (in particular, systems librarians and corporate information managers). areas of crossover identified included: managing risks, for example, related to intellectual property and data retention; structured and standardized approaches to (meta)data and information; technical skills such as systems analysis, database design and vendor management; and understanding and application of information standards and internal information technology and libraries | december 2018 29 information flows. while not a research library, within a broader information management context state archives and records nsw has promoted the benefits to records managers of working with enterprise architects, including improved program visibility, strategic assistance with business case development, and the embedding of recordkeeping requirements within the organization’s overall enterprise architecture.10 getting started: context and planning library technology services context in 2015–16, the awareness of enterprise and solution architecture expanded significantly within griffith university’s library technology services (lts) team. in 2015, some members of the team participated in activities led by external consultants to document griffith’s overall enterprise architecture at a high level. in 2016, the author became a member of the university’s solution architecture board (sab). lts submitted several smaller solution architectures to this group for discussion and approval, and team members found this process useful in identifying alternative ways to do things that we may not have otherwise considered. as a small team looking after a portfolio of high-use applications, lts was seeking to align itself as much as possible with university-wide it governance and strategy. these broader approaches included aggressively seeking to move services to cloud hosting, standardizing methods for transferring data between systems, complying with emerging requirements for greater it security, and participating in large-scale disaster recovery planning exercises. the author also needed to improve communication with senior it stakeholders. there was little understanding outside of the library of the scale and complexity involved in delivering online library services to a community of over 50,000 people. in a resource-scarce environment, it was increasingly important to make business cases not just in formal project documents but also opportunistically in less formal situations (the “elevator pitch”). existing systems were definitely hindering the library in making progress toward an improved online student experience and more efficient usage of staff resources. a complex ecosystem of more than a dozen library applications had developed over time. the library had selected these at different times based on requirements for specific library functions rather than alignment with an overall architectural strategy. our situation mirrored that described at cisti: “a complex and ‘siloed’ legacy infrastructure with significant vendor lock-in” combined with “reactionary” projects that “extended or redesigned [existing infrastructure] to meet purported needs, without consideration for the complexity that was being added to overcomplicated systems.”11 complex data flows between local systems and third-party providers that were critical to library services were not always well-documented. while lts staff members were extremely experienced, much of their knowledge was tacit. as in many libraries, staff could be observed sharing in informal, organic ways focused on the tasks at hand, but less effort was spent on capturing knowledge systematically. building a more explicit shared understanding about the library’s application portfolio would help address risks associated with staff succession. improved internal documentation would also address emerging requirements for team members to both develop their own understanding in new areas (upskilling) as well as become more flexible in terms of taking up broader roles and responsibilities across the team (cross-skilling). benefits of enterprise architecture for library technology management | searle 30 https://doi.org/10.6017/ital.v37i4.10437 there was also a sense that the time was right to take stock and evaluate the current state of affairs before embarking on any major changes. the team was supporting several applications, including the library management system and the interlibrary loans system, that were end-of-life. we needed to make decisions, and these needed to not only address our current issues but also provide a firm platform for the future. it was in this context that in 2016 library technology services approached the information technology architecture and solutions group for assistance. information technology architecture and solutions context in 2014, griffith university embarked on a new approach to enterprise architecture. the chief technology officer was given a mandate by the senior leadership of the university to ensure that it architecture was managed within an architecture governance framework, and the information services ea team was tasked with developing and maintaining an ea and providing services to support the development of solution architectures for projects and operational activities. two new boards were established to provide governance: the information and technology architecture board (itab) would control architectural standards and business technology roadmaps, while the solution architecture board (sab) would “support the development and implementation of solution architecture that is effective, sustainable and consistent with architectural standards and approaches.” project teams and operational areas were explicitly given responsibility to engage with these boards when undertaking the procurement and implementation of it systems. sets of architectural, information, and integration principles were developed, which promoted integration mechanisms that minimized business impact and were future-proof, loosely coupled, reusable, and shared services.12 our enterprise architects saw their primary role as maximizing the value of the university’s total investment in it by promoting standards and frameworks that could potentially improve consistency and reduce duplication across the whole organization. in order to do this , they would need to work with and through other business units. from the architects’ perspective, a collaboration with the library offered an opportunity to exercise skillsets and frameworks that were in place but still relatively new. griffith was still maturing in this area and attempting to move from the hiring of consultants as the norm to building more internal capability. working with the library would be a good learning experience for a junior architect, who was on a temporary work placement from another part of information services as a professional development opportunity. she could build her skills in a friendly environment before embarking on other engagements with potentially less open client groups. determining scope in a statement of architecture work once the two teams had decided that the process could have benefits on both sides, the next step was to jointly develop a statement of architecture work outlining what the process would include and how we would work together. a formal document was eventually endorsed at the director level, but prior to that, the librarians and the architects had a number of useful informal conversations in which we discussed our expectations, as well as the amount of time that we could reasonably contribute to the process. in developing the statement of work, the two teams agreed to focus on the current “as-is” environment and on assessment of the maturity of the applications already in use (see figure 1). this would help us immediately with developing business cases and roadmaps, without information technology and libraries | december 2018 31 necessarily committing either team to the much greater effort required to identify an ideal “to-be” (i.e., future) state to work towards. figure 1. overview of the architecture statement of work. full size version available at https://doi.org/10.6084/m9.figshare.6667427. the open group architecture framework (togaf) supports the development of enterprise architectures through four subdomains: business architecture, data architecture, application architecture, and technology architecture.13 the work that we decided to pursue maps to two of these areas: data architecture, which “describes the structure of an organization’s logical and physical data assets and data management resources;” and application architecture, which “provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes of the organization.” enterprise architecture process and outputs once the architecture statement of work had been agreed on, the two teams embarked on the process of working together over an extended period. while the lapsed time from approval of the statement of work through to endorsement of the architecture outputs by the solution architecture board was approximately fourteen months, the bulk of the work was undertaken within the first six months. following an intense period of information gathering involving large numbers of staff, a smaller subset of people then worked iteratively to refine the outputs for final approval. several times architecture activities had to be placed on hold in favor of essential ongoing operational work and higher priority projects, such as a major upgrade of the institutional repository. the process involved four main activities which are described in more detail in following sections. https://doi.org/10.6084/m9.figshare.6667427 benefits of enterprise architecture for library technology management | searle 32 https://doi.org/10.6017/ital.v37i4.10437 data asset and application inventory the first activity consisted of a series of three workshops to review information held about library systems in the ea management system, orbus software’s iserver. this is the tool used by the griffith ea team to develop and store architectural models, and to produce artifacts such as architecture diagrams (in microsoft visio format) and documentation (in microsoft word, excel, and powerpoint formats).14 the architects guided a group of librarians who use and support library systems through a process of mapping the types of data held against an existing list of enterprise data entities. in this context, a data entity is a grouping of data elements that is discrete and meaningful within a particular business context. for library staff, meaningful data entities included all the data relating to a person, to items and metadata within a library collection, and to particular business processes such as purchasing. we also identified the systems into which data were entered (system of entry), the systems that were considered the “source of truth” (system of record), and the systems that made use of data downstream from those systems of record (reference systems). the main output of this process was a workbook (figure 2) showing a range of relationships: between systems and data entities; between internal systems; and between internal systems and external systems. the first two columns in the worksheet contain a list of all the data entities and sub-entities stored in library systems (as expressed in the enterprise architecture). along the top of the worksheet is a list of all the products in our portfolio along with a range of systems they are integrated with. each of the orange arrows in this spreadsheet represents the flow of data from one system to another. the workbook in this raw form is definitely messy and the data within it is not really meant to be widely consumed in this format. the workbook’s main role is as the data source for the application communication diagram that is described in a later section. as a result of this data asset inventory, the management system used by our architects now contains a far more comprehensive and up-to-date view of the library’s architectural components than before: • the data entities better reflect library content. for example, while iserver already had a collection item data entity, we were able to add new data entity subtypes for bibliographic records, authority records, and holdings records. • library systems are now captured in ways that make more sense to us. workshopping with the architects led to the breakdown of several applications into more granular architectural components. for example, the library management system is now represented not just as a single system, but rather as a set of interconnected modules that support different business functions, such as cataloguing and circulation. similarly, our reading lists solution was broken down into its two main components: one for managing reading lists and one for managing digitized content. this granularity has enabled us to build a clearer picture of how systems (and modules within systems) interface with each other. information technology and libraries | december 2018 33 figure 2. part of the data asset and application inventory worksheet. full size version available at

https://doi.org/10.6017/ital.v37i4.10437 • the wide range of technical interfaces we have with third parties, such as publishers and other libraries, is now explicitly expressed. feedback from the architects suggested that the library was very unusual compared to other parts of the organization in terms of the number of critical external systems and services that we use as part of our service provision. previously iserver did not contain a full picture of these critical services, including: o the web-based purchasing tools that we use to interact with publishers, such as ebsco’s gobi;15 o the library links program that we use to provide easier access to scholarly content via google scholar;16 and o various harvesting processes that enable us to share metadata with content aggregators, such as the national library of australia’s trove service and the australian national data service’s research data australia portal. 17 application maturity survey the second activity was an application maturity assessment. this involved forty-four staff members from all areas of the library with different viewpoints (technical, non-technical, and management) answering a series of questions in a spreadsheet format. the survey contained questions about: • how often a system was used; • how easy it was to use; • how well it supported the business processes that person carried out; • how well it performed, for example, in terms of response times; • how quickly changes/enhancements were implemented in the product; • how easily the system could be integrated with other systems; • the level of compliance with industry standards; and • overall supportability (including vendor support). as different respondents were assigned multiple systems depending on their level of support and/or use, the final overall number of responses to the survey was 144 responses relating to eleven different systems. the outputs of this process were a summary table and a series of four graphs. the summary table (see figure 3) presents aggregated scores on a scale of one (low) to five (high) for each application as well as recommended technical and management strategies. it is interesting, and somewhat disheartening, to note that scores for the business criticality of the applications are generally much higher than the scores for fitness. there is also some variation in the strategies required; some systems need to be replaced, but there are others where the issues seem to be less technical. the third row of the table shows a product that is scored as highly business-critical and perfectly suited to the job from a technical perspective, yet the product still scores much more poorly for business fit, which could indicate that something has gone wron g in the way that this product has been implemented. information technology and libraries | december 2018 35 figure 3. table summarizing the results of the application maturity assessment [product names

major activity was the production of an application communication diagram (see figure 9). this is a visual representation of all of the information that was collated through the workshops using the

left. this represents the intota product suite from proquest, which contains multiple components, including our link resolver, discovery layer, and electronic resource manager. • physical technology. self-checkout machines appear as the small green box mid-right. • other internal systems that connect to library system components. examples of these are throughout and include: corporate systems, such as peoplesoft for human resources and finances; identity management systems like metadirectory and ping federate; the learning management system blackboard; and research systems, including the research information management system and the researcher profiles system. • external systems that connect to our systems. these are mostly gathered into the large grey box bottom right. • actors who access the systems. this includes administrators, staff, students, and the general public. actors are identified using a small person icon. • interfaces between components. each line in the diagram represents a unique connection into another system or interface. captions on these lines indicate the nature of the connection, e.g. manual data entry, z39.50 search, export scripts, and lookup lists. the production of this diagram has been an iterative process that has taken place over a long time period. the number of components involved in the diagram is quite large, so it is worth noting that the version presented here has actually been simplified. the architects’ tools can present information in different ways and this particular “view” was chosen to balance the need for detail and accuracy with the need to communicate meaningfully with a variety of stakeholders. production of interactive visualizations in the fourth and final work package, the data entity and application inventory spreadsheet was used as a data source to provide an interactive visualization (see figure 10). a member of the architecture team converted the workbook (see figure 2) from microsoft excel .xls into a .csv file. he developed a php script to query the file and return a json object based on the parameters that were passed. the data driven documents javascript library (d3.js) was used to produce a force graph that uses shapes, colors, and lines to visually present the spreadsheet information in a more interactive way.18 this tool enables navigation through the library’s network of data entities (shown as orange squares) and applications (shown as blue dots). in the example being displayed, the data entity “bibliographic records—marc” has been selected. it is possible to see both in the visualization and in the popup box on the left how marc records are captured, stored, and used across our entire ecosystem of applications. this visualization was very much an experiment and the value of this in the long term is something we are still discussing. in the short term, other outputs have proven to be more useful for planning purposes. information technology and libraries

https://doi.org/10.6017/ital.v37i4.10437 discussion the process described above was not without its challenges, including establishing a common language. enterprise architecture and libraries are both fertile breeding grounds for jargon and acronyms. there was also a disconnect in our understandings of who our users were, with the architects tending to concentrate on internal users, while the librarians were keen to include the perspectives of the academic staff and students who make up our core client base. these were minor challenges, and the experience of working with the enterprise architects was overall an interesting and positive one for the library. our collaboration validated mckay and parker’s view that there is much crossover in the skillsets and mindsets of librarians and enterprise architects.19 both groups tended to work in systematic and analytical ways, which was helpful in removing some of the more emotive aspects that might have arisen through a more judgmental “assessment” process. the enterprise architects’ job was to promote conformance with standards that are aspirational in many respects for the library. however, the collaborative nature of the process and the immediate usefulness of its outputs helped us to approach this as an opportunity to improve our internal practices as well as the services that we offer to library customers. the architects observed in return that library staff were very open-minded about the process; this had not necessarily always been their experience with other groups in the university. one reason for this may have been lts’s efforts to communicate early with other library staff. before embarking on this work, we sent emails and provided verbal updates to all participants and their supervisors. these communications were clear about both the time commitment needed for workshops and surveys and also about the benefits we hoped to achieve. short-term impacts in the library domain the level of awareness and understanding in library technology services about ea concepts and methods is much higher than what it was previously. our capacity to self-identify architectural issues is better as a result and this is enabling us to be proactive rather than reactive. a recent example of this is a request from our solution architecture board (sab) to seek an exemption from our it advisory board (itab) for our proposed use of the niso circulation interchange protocol (ncip) to support interlibrary loan. while ncip is a niso standard that is widely used in libraries, it is not one of the integration mechanisms incorporated into the architecture standards. as a result of this request, we plan to develop a document for these it governance groups about all the library-specific data transfer protocols that we use; not just ncip, but also z39.50, the open archives initiative protocol for metadata harvesting (oai-pmh), the edifact standard for transferring purchasing information, and possibly others. it is in our interests to educate these important governance groups about integration methods commonly used in the library environment, since these are not well understood outside of our team. the baseline as-is application architecture diagram gives us a much better grasp on the complexity we are faced with. understanding this complexity is a prerequisite to controlling it. the diagram, and the process worked through to populate it, makes it easier to identify manual processes that should be automated and integrations that might be done more efficiently or effectively. for example, like most libraries, we still have many scheduled batch processes that we could potentially replace in the future with web services to provide real-time updates. information technology and libraries | december 2018 43 the iserver platform is now an important source of data to support our decision-making, in terms of arriving at broad recommendations for replacing, reimplementing, or optimizing our systems as well as highlighting specific areas of concern. importantly, the process produced relative results, so that we can see across our application portfolio which systems are underperforming compared to others. this makes it easier to determine where the team should be putting its efforts and highlights areas where firmer approaches to vendor management could be applied. a practical example of this was our decision in late 2017 to review (and ultimately unbundle and replace) an e-journal statistics module that was underperforming compared to other modules within the same suite. the outputs from this process are also helping library technology services communicate, both within our own team and also with other stakeholders. the results of the application maturity assessment were included as part of a business case seeking project funding to upgrade our library management system and replace our interlibrary loans system. that funding bid was successful. while it is possible that the business case would have been approved regardless, a recommendation from the architects that the system needed to be replaced was likely more persuasive than the same recommendation coming solely from a library perspective. in our organizational context, enterprise architects are trusted by very senior executives; they are perceived as neutral and objective, and the processes that they use are understood to be systematic and data-driven. longer-term impacts in an enterprise context there are a number of longer-term impacts that may arise from this work. seeing the library’s applications in a broader enterprise context is likely to lead to more questioning of the status quo and to a desire to investigate new ways to do things. in large organizations like universities, available enterprise systems can offer better functionality and more standardized ways of operating than library systems. financial systems are an obvious example, as are business intelligence tools. the canned and custom reports and dashboards within library systems meet a narrow set of requirements, but do not compare well for increasingly complex analytics when compared to enterprise data warehousing, emerging “data lake” technologies for less structured data, and sophisticated reporting tools. an enterprise approach also highlights where the same process is being done across different systems. for example, oai-pmh harvesting is a feature of multiple systems at griffith. traditionally each system provides its own feeds. our data repository, publications repository, and researcher profile system all provide oai-pmh harvesting endpoints for sending metadata to different aggregators. an alternative solution to explore could be to harvest all publications data from multiple systems into our corporate data warehouse (particularly if this evolved to provide more linked data functionality) and provide a single oai-pmh endpoint that could then be managed as a single service. the ea process has further raised our already high level of concern with the current library systems market. there has been a move in recent years towards larger, highly-integrated “black box” solutions. while there have been some moves towards openness, for example through the development of apis, these are often rhetorical rather than practical. the pricing structures for products mean that we continue to pay for functionality that would not be required if we could integrate library applications with non-library enterprise tools in smarter ways. at griffith, the benefits of enterprise architecture for library technology management | searle 44 https://doi.org/10.6017/ital.v37i4.10437 products that scored most highly in our maturity assessment in terms of business and technical fit were the less expensive, lightweight, browser-based, cloud-native tools designed to do one or two things really well. this suggests that strategies around a more loosely coupled microservices approach, such as that being developed through the folio open source library software initiative, will be worth exploring in future.20 conclusion there are few documented examples of librarians working closely with enterprise architects in higher education or elsewhere. the goal of this case study is to encourage other librarians to learn more about architects’ work practices and to seek opportunities to apply ea methods in the library systems space for the benefit not just of the library but also for the organization as a whole. as a single institution case study, the applicability of this work may be limited in other environments. griffith has a long tradition of highly converged library and it operations; other organizations may have more structural barriers to entry if the library and it areas are not as naturally cooperative. a further obvious limitation relates to resourcing. the author of the cisti case study cautions that getting started in ea can be complex and resource-intensive. few libraries are likely to be in the position of cisti in having dedicated library architects, so working with others will be required. in many universities, work of this nature is outsourced to specialist consultants because of a lack of in-house expertise. at griffith university, we conducted this exercise entirely with in-house staff. a downside of this was that, despite our best efforts at the scoping stage, competing priorities in both areas meant that this work took far longer than we expected. in theory, external consultants could have guided the library through similar activities to produce similar outputs, and probably in a shorter timeframe. however, we would observe that the process has been just as important as the outputs; the knowledge, skills, and relationships that have been built will continue into the future. at cisti, investments in ea were assessed by the library as justified by the improvements in technology capability, strategic planning, and services to library users. the griffith experience validates this perspective. it is also important to note that ea work can and should be done in an iterative way. our experience suggests that some outputs can be delivered earlier than others and useful insights can be gleaned even from drafts. our local “ecosystem” of library applications, enterprise applications, and integrations between these different components mus t respond to changes in technologies; legal and regulatory frameworks; institutional policies and procedures; and other factors. it is therefore unrealistic to expect outputs from a process like this to remain current for long. assuming that the library’s data and application architecture will always be a work-in-progress, it will continue to be worth the effort involved to build and maintain positive working relationships with the enterprise architects, who now have a deeper understanding of who we are and what we do. acknowledgements

visualizations discussion short-term impacts in the library domain longer-term impacts in an enterprise context conclusion acknowledgements references in march 2003 the university of mississippi libraries made our metasearch tool publicly available. after a year of working with this product and integrating it into the library web site, a wide variety of libraries interested in our implementation process and experiences began to call. libraries interested in this product have included consortia, public, and academic libraries in the united states, mexico, and europe. this article was written in an effort to share the recommendations and concerns given. much of the advice is general and could be applied to many of the metasearch tools available. google scholar and other open web initiatives that could impact the future of metasearching are also discussed. m any libraries are looking for ways to facilitate the discovery process for users. implementing a one­stop search product that does not require database­specific knowledge is one of the paths librar­ ies are choosing.1 as these search engines are made available to patrons, the burden of design falls to the library as well as to the product developers. most library users may be familiar with a few databases, but the vast majority of electronic resources remain unrevealed. using a metasearch product, a single search is broadcast out to similar and divergent electronic resources, and search results are returned and typically mixed together. metasearch results are returned in real­time and link the user to the native interface. although there are many products that support one­stop searching, the university of mississippi libraries chose to purchase innovative interfaces’ metafind product because it tied into a digital initiative partnership with innovative. some of the possibilities of the types of resources you can search include: n library catalogs n licensed databases n locally created databases n full text from journals and newspapers n digital collections n selected web sites internet search engines the simplicity of google searching is very appeal­ ing to users. in fact, users have come to expect this kind of empowering tool. at the university of mississippi, students use and have been using google for research. as google scholar went public, it became evident that university faculty also use it for the same reasons. it was apparent from the university of mississippi libraries’ 2003 libqual+ survey results that users would like more personal control than the library was offering (table 1). unintentionally elaborate mazes are created and users become lost in a quagmire of choices. as indicated by our libqual+ survey results, our users want easy­to­use tools that allow them to find informa­ tion on their own, and they want information to be easily accessible for independent use. these are clearly two areas that many libraries are struggling to improve for their patrons. the question is how to go about it. based on several changes made between 2003 and 2005, which included implementing a metasearch tool, the adequacy mean improved for both questions and for undergradu­ ates as well as graduate students and faculty (table 2). the adequacy mean compares the minimum level of ser­ vice that a user expects with the level of service that they perceive. in table 1, the negative adequacy mean figures indicate that the library was not meeting users’ minimum level of service for these two questions or that the per­ ceived level of service was lower than the minimal level of service. table 2 compares the adequacy mean from 2005 with 2003 and indicates a notable, positive change in adequacy mean for each question and with each group. n design perspectives and tension generally, there are conflicts within libraries regarding the question of how to improve access for patrons and allow for independent discovery. for those leading a metasearch implementation, these tensions are important to understand. in implementing new technologies, there are key development issues that may decrease internal acceptance until they are addressed. however, one may also find that there are some underlying fears regarding this technology. although the following cross­subculture comparisons simply do not do justice to each of the valid perspectives, these brief descriptions highlight the types of perspectives one might encounter when considering or implementing a metasearch product. expert searchers prefer native interfaces and all of the functionalities of the native interface. they are typically unhappy with the “dumbed­down” or clunky searching of a metasearch utility. they would prefer for patrons to be taught the ins and outs of the database they should be using for their research. this presupposes that the students either know which database to use, will spend time inves­ tigating each database on their own, or that they will ask for assistance. however, there are clearly native interface 44 information technology and libraries | june 2007 metasearching and beyond: implementation experiences and advice from an academic library gail herrera gail herrera (gherrera@olemiss.edu) is assistant dean for technical services & automation and associate professor at the university of mississippi. metasearching and beyond | herrera 45 functionalities—such as lim­ iting to full text—that, while wonderful to patrons, are not consistent across resources or a part of the metasearch standard. users would cer­ tainly benefit if limiting to full­text was ubiquitous among vendors and if there were some way to determine full­text availability within metasearch tools. results ranking is another issue that expert searchers may bring to the table. currently, there is a niso metasearch initiative that is striving to standard­ ize metasearching.2 another downside for the expert searcher is that there is no browse function. those who are in administrative or manage­ rial positions working with electronic resources see metasearching as an opportunity to reveal these resources to users who might not otherwise discover them. for example, many users have learned to search ebsco’s academic search premier not realizing that key articles on a local civil rights figure such as james meredith are also available in america: history & life, jstor, and lexisnexis. metasearching removes the need for the user to spend additional time choosing databases that seem relevant and searching them indi­ vidually. from a financial perspective, if a library is pay­ ing for these electronic resources, they should be using them as much as possible. and while the university of mississippi libraries generally target the undergraduate audience with our metasearch tool, the james meredith search is a good example of how a metasearch tool might reveal other databases with information that a serious researcher could then further investigate by link­ ing through the citation to the native interface. those associated with library instruction may also be uncomfortable with metasearching. in fact within a short time of implementing the product, several instructors conveyed their fear that in making searching so simple, they would no longer have a job as the product developed. generally, it seems that users are always in need of instruc­ tion although the type of instruction and the tools continue to change. it is an understandable fear and one that would be wise to acknowledge for those embarking on a metasearch implementation. while metasearch can be an empowering tool for users, you may also encounter some emotional reactions among library employees. from an information literacy point of view, frost has noted that metasearching is “a step backward” and “a way of avoiding the learning process.”3 it is true that in providing an easy search tool, the library is not endeavoring to teach all students intermedi­ ate or advanced information retrieval knowledge or skills. however, it is important to provide tools that meet users at their level of expertise and as previously noted, this is an area identified in need of improvement. for those working at public service points such as the reference desk, metasearching is an adjustment. many times those working with patrons tend to use databases with which they are more familiar or in which they feel more confident. federated search tools may reveal resources that are typically less used and therefore unfa­ miliar to library employees. training may then become an issue worthy of addressing not just for the metasearch interface and design but also for the less­used resources. for those involved in technical support, this product may range from exciting to exasperating. the amount of time your technical support personnel have to dedicate to your metasearch project should be a major factor when investigating the available products. just like any other technological investment, you are either going to (1) purchase the technology and outsource manage­ ment or (2) obtain a lesser price from a vendor for the tool and invest in developing it yourself. there is also a middle ground, but this cost­shifting is important to keep in mind. regardless of your approach, it is critical to include the technical support person on your imple­ mentation team and to keep in mind the kind of time investment that is available when reviewing prices. along with developing this product, one may also find oneself investing additional time and money into infra­ structural upgrades such as the proxy server, network equipment, or dns servers. in addition to these perspectives, there is a general tension in library web site design philosophies between how librarians would like patrons to use their services table 1. 2003 libqual adequacy mean undergrad grad faculty easy-to-use access tools that allow me to find things on my own -.10 -.30 -.29 making information easily accessible for independent use .37 -.09 .03 table 2. positive change in libqual adequacy mean from 2003 to 2005 undergrad grad faculty easy-to-use

patrons want. the traditional design based on educating users and having users navigate to information “our way” has definitely curtailed over the past several years with attention being paid increasingly to usability. as usability studies give librarians increasing informa­ tion, libraries are moving toward designing for our users based on their approaches and needs rather than how librarians would have them work. depending on where one’s library is in this spectrum of design philosophy, implementing a metasearch tool may be harder or easier. judy luther surmised the situa­ tion well, “for many searchers, the quality of the results matter less than the process—they just expect the process to be quick and easy.”4 moving toward this lofty goal is to some extent dictated by the abilities and inabilities of the technologies chosen. as a technologist, the general rule seems to be that the easier navigation is made for our users; the more complex the technical structure becomes. n metasearch categories in arranging categories of searches for a metasearch product, some libraries group their electronic resources by subject, and others use categories that reflect full­text avail­ ability. the university of mississippi libraries use both. the most commonly used category is our full­text category. this full­text category was set as the default on our most popular search box located on our articles and databases web page (figure 1). since limiting to full­text materials is not a standard, the category was defined by the percentage of full­text they contain. this is an important distinction to understand because a user may receive results that are not full­text, but the majority of results will likely be full­text. at our library, if the resource contains more than 50 percent full­text, it is included in the full­text category. other categories included in this implementation are ready reference, library catalogs, digital collections, lim­ ited resources, publicly available databases, and broad subject categories. one electronic resource may be included in the full­text category, a broad sub­ ject category such as “arts and humanities” and also have its own individual category in order to mix and match individual resources on sub­ ject guides using a tailor­made search box. the limited resource category contains resources that should be searchable using the metasearch tool but that have a limited number of simultaneous users. if it were included in the default full­text category that is used so much, it would tie up the resource too much. investigating resources with only one or two simultaneous users at the begin­ ning of the project may help you avoid error messages and user frustration. one might wonder, “why profile limited resources then?” there may be specific search boxes on subject guides where librarians decide to add that individual but limited resource. it might also be necessary to shorten the time­out period for limited user resources. along those same lines, having pay­per­search resources profiled could also be expensive and is not recommended. since the initial implementation, migrating away from per­ search resources has become a priority. within the first few months of implementation, the free resources such as pubmed and askeric were moved to a new “publicly available” category. the reason is that since there is not any authentication involved, these results return very quickly and are always the first results a user sees. while they are important resources, our intent was really to reveal our subscription resources. this approach allows users to search these resources if specifically chosen but they are not included in the default full­text category. this approach does still allow subject librarians to mix and match these free individual resources on subject guide search boxes. n response time of all of the issues with our metasearch tool, response time has been the most challenging. there are so many issues when it comes to tracking down sluggish response that it can be extremely difficult to know where to start. if one’s metasearch software is not locally hosted, response time could involve the library network, campus network, off­campus network provider, and the vendor’s network, not to mention the networks of all the electronic resources users are searching. when one adds the other variable of authentication, the picture becomes even more over­ whelming and difficult to troubleshoot. for authentication, the university of mississippi libraries purchased innovative’s web access management module (wam), which is based on the figure 1. metasearch tailored search box with full text category selected metasearching and beyond | herrera 47 ezproxy software. as the use of our electronic resources from on­campus and off­campus has grown, the inci­ dence of increasing network issues has risen. in work­ ing with our campus telecommunications group, the pursuit of ever­greater bandwidth has become a priority. troubleshooting has included tracking down trouble­ some switch settings, firewall settings, as well as campus dns and vendor dns issues. if your network adminis­ trators use packet shapers, this may be another hurdle. clearly, our metasearch product has placed a significant load increase on the proxy server. in looking at proxy statistics, 24 percent of total proxy hits were from the metasearch product (figure 2). with this in mind, one may find the load on one’s proxy server increasing very dramatically during peak usage and may need to plan for upgrades accordingly. even with improvements and tweaks along the way, response time is still an issue and one of the highest hurdles in selling a metasearch product internally and externally. one metasearch statistical module includes response time information for individual resources along with usage data. the response time information would be very helpful in troubleshooting and in working with electronic resource vendors. usage tracking is another criterion to consider in reviewing metasearch products. n response time and tailored search boxes during implementation, one of the first discussions to have is who will be the target audience for this product. at this institution, undergraduates were the target audi­ ence and more specifically, those looking for three to five articles for a paper. while our metasearch software has a master screen showing all of the resources divided into the main categories, facing users with over sixty check boxes was not a good solution (figure 3). this master screen is good for demonstrating categories to library staff, overall functionality of the technology, and also for quickly checking all of your resources for connectivity errors. from early conversations with students, keeping basic users far away from this busy screen is a good goal. remember, the purpose is to give them an easy starting point. the best way to keep users in a simple search box is to construct search boxes and hand­pick either individual resources or categories keep­ ing in mind the context of the web page. for example, the articles and databases page has a simple search box that searches for articles. subject guide boxes search individual electronic resources selected by the subject librarian. the university of mississippi libraries also have a large col­ lection from the american institute of certified public accountants (aicpa). the search box on that page searches our catalog, which contains aicpa books along with the aicpa digital collection. some libraries are interested in developing a standard metasearch box to display as a widget or standing content area throughout their web site. this is interesting and worth considering. however, matching the web page content with appropri­ ate resources has been our approach. as the standards and technology develop, this may be worth further con­ sideration depending on usability findings. for the most commonly used search box on the articles and databases page (figure 1), the default category checked is the full­ text articles category. donna fyer stated that, “for the average end user, the less decision making, the better.”5 this certainly rings true for our users. originally, a simple metasearch search box was placed on the library homepage. the library catalog and the basic metasearch box were both displayed. this seemed confusing for users since both products have search capabilities. with the next web site redesign, the basic metasearch box moved from the library homepage to the articles and journals web page. this was a success­ ful place for the article quick search box to reside since the default was set to search the full­text category. there were some concerns that users might be typing journal titles into the search box but these were rare instances and not necessarily inappropriate uses. the next rede­ sign eventually moved this search box to the articles and databases page, where it remains. for the articles and databases pages, the simple search box (figure 1) by default searches the full­text category and searches the title keyword index. the index category with the label, “article citations,” can also be checked by the user. the majority of metasearches begin with this search box and figure 2. total proxy hits vs. metafind proxy hits 4� information technology and libraries | june 2007 most users do not change the default settings for the resources or the index. n subject guide search boxes in addition to the “article quick search” box, subject librarians slowly became interested in a search box for their subject guides as the possibili­ ties were demonstrated. in order to do this, the ven­ dor was asked to profile each resource with its own unique value in order to mix and match individual resources. while the idea of searching resources by subject category sounds useful and appealing, sometimes universal design begets universal dis­ cord. even with a steering committee involved, it is hard for everyone to agree what resources should be in each of the main subject categories: arts and humanities, science and engineering, business and economics, and social science. some libraries have put a lot of time and effort into creating a large number of subject categories. the master search screen (figure 3) displays several of this library’s categories but not the broad subject categories noted above. these general sub­ ject categories are brought out in the multipurpose interface called the “library search engine” (figure 4). the library search engine design is a collection of the categories and resources showing the full functionality of our metasearch tool. the subject categorization approach within our metasearch interface is a good way to show the multifunction­ ality of the product but remains relatively unused by patrons. by giving each resource its own value, subject librarians have the flexibility to select spe­ cific resources and/or categories for their subject guides. it is worth noting that it required additional setup from our vendor and was not part of the original implementation. after a few months of testing with the initial implemen­ tation, willing subject librarians chose individual resources for their tailored search boxes. once a simple search box has been constructed, it can be easily copied with minor modi­ fications to make search boxes for those requesting them. while progress was slow to add these boxes to subject guides, after about a year there was growing interest. in setting these up, subject librarians have several choices to make. first of all, they choose the resources that will be searched. for example, the biology subject guide search box searches academic search premier, bioone, and jstor by default. basicbiosis and pubmed are also avail­ able but are not checked by default. users can check these search boxes if they also wish to search these resources. choosing the resources to include in the search box as well as setting what resources are checked by default is the most important decision. the subject librarian is also encour­ aged to assist in evaluating the number of hits per resource returned. with response time being a critical factor, deter­ mining the number of hits per resource should involve testing and take into consideration the overall number of resources being searched. n relevance selecting the default index is another decision in setting up search boxes. again, users are google­oriented and tend to go with whatever is set as the default option. out of the box, our metasearch tool defaults to the keyword index or keyword search. the issue of relevancy is a hot topic for metasearch products. this issue typically comes up in metasearch discussions. it is also listed as an issue in the niso metasearch initiative. from the technical side of the equation, results are displayed to the user as soon as they are retrieved. this allows users to begin immediately exam­ figure 3. master screen display (partial screenshot) figure 4. library search engine subject categories metasearching and beyond | herrera 4� ining the results. adding a relevancy algorithm as a step would mean all of the results would have to be returned, ranked, and then displayed. with response time being a key issue, a faster response is more important than relevance. another consideration is if the metasearch results are displayed to the user as interfiled or by electronic resource where the resource is returning results based on its own relevancy rankings. one way to increase relevance is to change the default index from keyword to title keyword. for our students, bringing back keywords in the title made the results more relevant. this is the default index used for our article search on the articles and database web page. subject librarians have the choice of indexes they prefer when blending resources. one caveat in using title keyword is that there are resources that do not support title keyword searching. for other resources, title keyword is not an appropriate index. for example, wilson biographies does not have a title keyword search. it makes perfect sense that a biography database would not support title keyword searching. in these cases, the search may fail and note that the index is not supported. to accommodate this type of exception, the profile for wilson biographies needed to be changed to have the title keyword search­mapped to a basic keyword search. while this does not make the results as relevant as the other search results, it keeps any errors from appearing and allows results to be retrieved. n results per source and per page for metafind, there are also two minor controls that can work as hidden values unseen by the patron or as compo­ nents within the search box for users to manipulate. the first control is the number of hits to return per resource. if a subject librarian is only searching two or three resources in his tailored search box, he probably will want to set this number higher. if there are many resources, this number should be lower in order to keep response time reasonable. the second control is the number of results to return per page. in general, it is important to adjust these controls after testing the response for the resources selected. while users typically use the default settings, showing these two con­ trols gives the user a visual clue that the metasearch tool is not retrieving all of the results from the resource. instead, it is only retrieving the first twenty­five, for example. n implementation advice one of the most important pieces of advice is that it is extremely important to have a date in one’s contract or rfp for all of the profiling to be completed if the vendor is doing the resource profiling. from this library’s experi­ ence, the profiling of a resource can take a very long time, and this is a critical point to include in the contract. one might also consider adding cost and turn­around time for new resources after the initial implementation to the contract. the more resources profiled, the more useful the product. however, one also needs to pay attention to response time. if the plan is to profile one’s own resources or connectors, librarians should be mindful of the time involved and ask other libraries with the same product about time investments. being able to work with vendors who will provide an opportunity to evaluate the product “live” is preferable. in deciding who to target for an implementation team, consider representatives from reference, collection development, and systems. it is also very important to include whoever manages electronic resource access/ subscriptions and a web manager. in watching other pre­ sentations, exclusion of any of these representatives can seriously undermine the implementation. buy­in is essen­ tial to success. additionally, giving librarians as many options as possible, such as control over what types of resources are in their search boxes as well as the number of hits per resource makes the product more appealing. n questions to ask once the implementation team is set, interviewing refer­ ences for the products under consideration is an impor­ tant part of the process. unstructured conversations with references really allow librarians to explore together what the group wants and how its needs fit with the services the vendor offers. a survey of questions via e­mail is another possibility. in choosing this method, be sure to leave some room for open comments. regardless of the approach, it is important to spend some time asking ques­ tions. provided are a list of recommended questions: n who is responsible for setting up each resource—the vendor or you? n how much time does it typically take to set up a new resource and what is the standard cost to add a new resource? n is there a list or database of already­established pro­ files for electronic resources for this product? n how much time would you estimate that it took to implement the product? n will you be able to edit all of the public web pages yourself or will you be using vendor support staff to make changes? if the vendor support staff has to make some of the changes, how responsive are they? 50 information technology and libraries | june 2007 n can you easily mix and match individual resources for subject guides, departmental pages, or other kinds of web pages? or do you only have the option to set up global categories? n is your installation local or does the vendor host it? are there response issues? n is there an administrative module to allow you to maintain categories, resource values, and configura­ tion options? n how much time goes into managing the product monthly? and who manages the product at your library? n what kind of statistical information does the vendor provide? n how satisfied are you with the training, implementa­ tion support, and technical documentation? n how does the vendor handle broken resources or subscription changes? as with most technologies, there are upfront and hid­ den costs. it is important to determine what hidden costs are involved and if you have the resources to support all of the costs. sometimes libraries choose the least expen­ sive product. however, this approach can lead librar­ ies down the path of hidden costs. for example, if the product is less expensive but your library is responsible for setting up new electronic resources, managing all of the pages, and finding ways to monitor and troubleshoot performance outside of the tools provided, the hidden expenditures in time and training may be more costly in the end than purchasing the premium metasearch tool. in essence, one must pay for the product one way or another. the big question is, where are the resources to support the product? if one’s library has more it/web personnel than money, the lower­costing product may be the way to go, but be sure to check with other librar­ ies to see if they have been able to successfully clear this hurdle. additionally, if your library has more one­time money than yearly subscription money, this may dictate the details of the rfp, and your library may lean toward a purchase rather than an annual subscription. n metasearch summary clearly, students want a simple starting place for their research. implementing a metasearch tool to meet this need can be a hard sell internally for many reasons. at this institution, response time has been the overriding critical issue. response has lagged due to server and network issues that have been difficult to track down and improve. however, authentication is truly the most time­ consuming and complex part of the equation. some fed­ erated search tools are actually searching locally stored information, which helps with response. while these are not truly metasearch tools and are not performing real­ time searches, this approach may yield more stability with faster response. over the years in implementing new services such as the library web site, illiad, electronic resources, and off­ campus authentication, new services are often adopted at a much faster rate by library users than by library employees. typically, there will be early adopters who use the services immediately based on need. it then takes general users about a year to adopt a new service. iii’s metasearch technology has been available for the past four years. however, our implementation is evolving with each web site redesign. still, it is used regularly. the university of mississippi libraries has been pro­ viding access to its electronic resources in two distinct ways: (1) providing urls on web pages to the native interface of the electronic resource and (2) metasearching. as the library moves forward in developing digital col­ lections and the number of electronic resources profiled for metasearching increases, it is possible that this kind of global discovery tool will compete in popularity with the library catalog. providing such information mining tools to patrons will cause endless frustration for the library literate. response times, record retrieval order, as well as licensing and profiling issues, are all obstacles to pro­ viding a successful metasearch infrastructure. retrieval inconsistency and ad hoc retrieval order of records is very unsettling for librarians. however, this is the kind of tool to which web users have become accustomed and certainly seems to fill a need that to date has been lacking where library electronic resources are concerned. n open web developments one other trend appearing is scholarly research discovery tools on the open web. enter google scholar along with other similar initiatives such as windows live academic search. google scholar beta was released in november 2004 and very soon after began an initiative to work with libraries and their openurl resolvers.6 this bridging between an open web tool and libraries is an interest­ ing development. a fair amount has been written about google scholar to date although the project is still in its beta phase. what does google scholar have to do with metasearching? good question. it remains to be seen how much scholarly information will become search­ able via google scholar. for now, the jury is still out as to whether google scholar will begin to encroach upon the traditional territory of the indexing and abstracting world. if sufficient content becomes available on the open web, whether from publishers or vendors allowing their metasearching and beyond | herrera 51 content to be included, then the authentication piece that directly effects response time may be overcome. in using google scholar or other such open web portals, search­ ing happens instantly. when a user uses the openurl resolver to get to the full­text, that is where authentication enters into the picture and removes the negative impact on searching. the tradeoff is that there are many issues involved in openurl linking and the standardization of the metadata needed to provide consistent access. there are many parallels between what google scholar is attempting to offer and what the promises of metasearching have been. for metasearching, under­ graduate students looking for their three to five articles for a paper are considered our target audience. for in­ depth searching, metasearching does have limitations, but for the casual searcher looking for a few full­text articles, it works well. interestingly, similar recommen­ dations are being made for google scholar.7 however, opinions differ on this point. roy tennant went so far as to indicate it is a step forward in access to those users without access to licensed databases, but remained reserved in his opinion regarding the usefulness for those with access.8 google scholar also throws in a few bonuses. while providing access to open access (oa) materials in our opac for specific collections such as the directory of open access journals, these same resources have not been included in our metasearch discovery tool. google scholar is searching these open repositories of scholarly informa­ tion, although there is some concern over the automatic inclusion of materials such as syllabi and undergraduate term papers within the institutional repositories.9 google scholar also provides a useful citation feature and rel­ evancy. google scholar recognizes the user’s preference for full­text access and provides a visual cue from the brief results when article full­text is available. this func­ tionality is not currently available from our metasearch software but would be extremely helpful to users. on the downside, some of google scholar’s linking policies make it difficult for libraries to extend services beyond full­ text articles to their users. another notable development among subscription indexing services is the ability to reveal content to web search engines. ebsco’s initiative is called ebscohost connection.10 in implementing metasearching, libraries have debated about providing access to free versus subscrip­ tion resources. for our purposes, free resources were not included in the most commonly used search in the full­ text category. there are those who would argue against this decision, and they have very good points. in fact, it has already been noted that some libraries use google scholar to verify incomplete interlibrary loan citations quickly.11 in watching the development of google scholar, it seems possible that this free tool that uncovers free open access resources and institutional repository mate­ rials may not necessarily be a competitive product, but may be a very complementary one. n impact on the opac what will this mean for the “beloved” opac? for a very long time, users have expected more of the library catalog than it has provided. while the library catalog is typically appreciated by library personnel, its usefulness for finding materials other than books has been hard for general users to understand. many libraries including the university of mississippi have been loading records from their electronic resources in hopes of making the library catalog more useful. the current conversation regarding digital library creation also begs the question, “what is the library catalog?” although the library catalog serves as a searchable inventory of what the library owns, it is simply a pointing mechanism, whether it points the user to a shelf, a building, or a url. in our endeavor to provide instant gratification and full­text, as well as the user’s desire for information regardless of format, the library catalog is beginning to take a backseat. it was clear four years ago in plan­ ning digital collections that a metasearch tool would be needed to tie together subscription resources, digital collections, publicly available resources, and the library catalog. it will be interesting to see whether patrons choose to use the formal tools provided by the library or the informal tools developing on the open web, such as google scholar, to perform their research. more than likely, discovery and access will happen through many avenues. while this may complicate the big picture for those in library instruction, it is important to meet users on the open web. one’s best intentions and designs are presented to users but they may choose unintended paths. librarians should watch the paths they are taking and build upon them. sometimes even one’s best attempts fall short, as pointed out clearly in karen schneider’s latest series, “how opacs suck.”12 still it is important to acknowl­ edge design shortcomings and keep forging ahead. dale flecker, who spoke at the taiga forum, recommended not to spend years trying to “get it right” before imple­ menting, but instead to consider ourselves in perpetual beta and simply implement and iterate.13 in other words, do not try to make the service perfect before implement­ ing it. most libraries do not have the time and resources to do this. instead, find ways to gain continual feedback and constantly adjust and develop. students are familiar with internet search engines and do not want to choose between resources. access to a simple resource discovery tool is an important service for users. unfortunately, authentication, product design 52 information technology and libraries | june 2007 and management, and licensing restrictions tend to be stumbling blocks to providing fast and comprehen­ sive access. regarding the metasearch tool used at the university of mississippi libraries, development part­ nerships have already been formed between the vendor and a few libraries to improve upon many of the issues discussed. innovative is developing a next­generation metasearch product called research pro that leverages ajax technology. while efforts are made to participate in discussions and develop our already­existing tools, it is also impor­ tant to pay attention to other developments such as google scholar. at this point, google scholar is in beta but this kind of free searching could turn the current infra­ structure on its ear to the benefit of patrons. the efforts to meet users on the open web and reveal scholarly content are definitely worth keeping an eye on. references 1. roland dietz and kate noerr, “one­stop searching

for its research guides. a large interdepartmental team sought user feedback on the design, content, and organization of the guide homepage, as well as on individual subject guides. this information was collected using an open-card-sort study, two face-to-face, think-aloud testing protocols, and an online survey. significant findings include that users need clear directions and titles that incorporate familiar terminology, do not readily understand the purpose of guides, and are easily overwhelmed by excess information, and that many of librarians’ assumptions about the use of library resources may be mistaken. this study will be of value to other library workers seeking insight into user needs and behaviors around online resources. introduction like many libraries that employ springshare’s popular libguides platform for creating online research resources, the university of houston libraries (uhl) has accumulated an extensive collection of guides over the years. by 2015, our collection included well over 250 guides, with varying levels of complexity, popularity, usability, and accessibility. this presented a major challenge when we planned to migrate our libguides instance (locally branded as “research guides”) to libguides v2 in fall 2015, but also an opportunity: the transition would be an ideal time to appraise, reorganize, and streamline existing guide content. although uhl had conducted user research in the past to improve usability, in preparing for the migration it became clear that another round of tests would be beneficial in revising our guides for the new platform. our research guides would be presented much differently in libguides v2, and the design and organization of information would need to be tailored to the needs of our user community like any other service. user feedback would be vital to reorganizing our guides’ content and to making customizations to the new system. this article will describe the usability testing process that was employed before and after uhl’s migration to libguides v2. usability testing is one technique in the field of user experience (ux). the primary goal of ux is to gain a deep understanding of users’ preferences and abilities, in order to inform the design and implementation of more useful, easy-to-use products or systems. best practices for ux emphasize “improving the quality of the user’s interaction with and perceptions of your product and any related services.”1 usability tests conducted as part of this case study mailto:lierman@rowan.edu mailto:bscott3@uh.edu

pioneered several ux ideas and techniques, and the explanations on conducting your own usability testing provided in steve krug’s seminal works on the topic, don’t make me think and rocket surgery made easy. uhl’s transition to libguides v2 consisted of five stages: (1) card sort testing to determine the best organization of guides in the new system; (2) the migration itself; (3) face-to-face usability testing after migration to study user expectations and behavior after the change; (4) a survey to identify any significant variations in distance users‘ experiences; and (5) final analysis and implementation of the results. incorporating usability testing was a relatively easy and inexpensive process with a high yield of useful insights, which could be adapted as needed to other library settings in order to evaluate similar online resources. literature review as libraries have moved from traditional paper pathfinders to online research guides of increasing sophistication, there has been substantial study into the effectiveness of online research guides for various audiences and information needs. several studies highlight the apparent disconnect between students’ and librarians’ perceptions of research guides, especially regarding the purpose, organization, and intended use of the guides. reeb and gibbons used an analysis of surveys and web usage statistics from several university libraries to show that students rarely or never used online guides despite the extensive time spent by librarians to curate and present information resources.2 similarly, in courtois, higgins, and kapur’s one-question survey (“was this guide useful?”) the authors were surprised to find that 40 percent of the responses received rated guides unfavorably, noting that “it was disheartening for many guide owners to receive poor ratings or negative comments on guides that require significant time and effort to produce and maintain.”3 hemmig concluded that in order to increase the value of a guide from a user perspective, librarians must adopt a user-centric approach by guiding the search process, understanding students’ mental models for research, and providing “starter references.”4 staley’s survey of student users also indicates a need to be mindful of what resources guides are actually expected to provide, as it found that pages linking to articles and databases were far more used than pages with other content.5 data has also shown that undergraduate students are unable to match their information needs with the resources provided on broad subject-area guides, leading several authors to conclude that students would be able to use course-specific guides more easily. for instance, strutin found that course guides are among the most frequently used guides, especially when paired with library instruction sessions.6 several other studies cite survey data, statistics, and educational concepts like cognitive load theory to conclude that ideally, guides would be customized to the specific information needs of each course and its assignments in order to better match the mental models and information-seeking behavior of undergraduate students.7 while the value of online research guides has been under study for quite some time, usability testing of guides is a relatively recent phenomenon. in 2010, librarians at concordia university conducted usability testing of two online research guides and found that undergraduate students generally found the guides difficult to use.8 librarians at metropolitan state university conducted two rounds of usability tests on their libguides with a broader range of participant types, highlighting the ability to incorporate usability testing as part of an iterative design process.9 at ithaca college, subject librarians partnered with students in a human-computer interaction information technology and libraries | december 2019 78 course to test both course guides and subject guides through a series of usability tests, preand post-test questionnaires, and a group discussion in which students evaluated the findings of the usability tests and discussed their experiences.10 at the university of nevada, las vegas, librarians conducted usability testing with both undergraduate students and librarians, and surprisingly found that attitudes towards the guides were similar in both groups: interface design challenges were the greatest barrier to task completion, rather than the level of expertise of the user.11 finally, at northwestern university, librarians conducted several types of usability tests as a part of a transition from the original libguides platform to libguides v2, to determine what features worked from the original guides and what could be improved or updated during the migration.12 throughout these and other usability studies, the authors have identified a number of desirable and undesirable elements in research guide design: • clean and simple design is highly prioritized by users. students preferred streamlined text, plentiful white space, and links to “best bets” rather than comprehensive but overwhelming lists of databases.13 these findings also align with accepted web design best practices. • guide parts and included resources should be labeled clearly and without jargon.14 sections and subpages within each guide should be named according to key terms that students recognize and understand. also, librarians should consider creating subpages using a “need-driven approach,” based on the purpose of each research task or step, rather than by the format of materials or resources.15 • the tabbed navigation of libguides v1 is both unappealing to and easily missed by users, and if it must be implemented, great care should be taken to maximize its visibility and usability.16 • consistency of guide elements, both within a guide and from one guide to the next, helps users more easily orient themselves when using guides; certain elements should always be present in the same place on the page, including navigational elements and table of contents, contact information, supplemental resources such as citation and plagiarism information, and common search boxes.17 with the findings and recommendations of these predecessors in mind, we designed a multi-stage study to expand upon their results and identify new challenges and opportunities that the libguides v2 platform might present. methodology stage 1: card sort the majority of research guides at uhl are organized by subject area, by course, or both. there are a number of guides, however, that are not affiliated with any particular subject area or course, containing task-oriented information that may be valuable across a wide variety of disciplines. the organizational system for these guides had developed organically over time as new guides were developed, rather than being structured intentionally, and it had become evident that these guides were not particularly discoverable or well-used by students. the migration to libguides v2 presented an opportunity to reorganize these guides based on user input. a team of three librarians from the liaison services department conducted an open-card-sort study in november 2015, in order to determine how best to organize those research guides not already affiliated with a course or subject area. card sorting is a method of identifying the testing for transition | lierman, scott, warren, and turner 79 https://doi.org/10.6017/ital.v38i4.11169 categories and organization of information that make the most sense to users, by asking users to sort potential tasks into named categories representing the menus or options that would be available on the site. an open-card sort allows users to create and name as many categories as they need, as opposed to a closed-card sort, which requires users to sort the available options into a predetermined set of categories. to prepare for the study, we reviewed all of our guides to develop a complete list of those not affiliated with a subject or course. for each guide, we developed a brief, clear description of the guide’s topic that would be easy for an average library user to understand, each on a small laminated card. over an approximately ninety-minute period, we staffed a table in the 24-hour lounge of m.d. anderson library, where we recruited passersby to participate in the study. after answering a few demographic questions, participants were asked to place the cards into groups that seemed logical to them. they could create as many or as few groups as necessary, but were asked to try to place every card in a group. while the participants organized the cards, they were asked to explain their thought processes and rationale, and one librarian observed the sorting process and took notes on their actions and explanations. when a participant finished grouping the cards, they were asked to write on an index card a name for each of the groups they had created. the final groupings were photographed and the labels retained for recording purposes. after the testing was complete, participants’ responses were organized into a spreadsheet and reviewed for recurring patterns and commonalities. a new set of categories was developed based on those most commonly created by students during the study, and these categories were titled using the most common terminology used by students in their group labels. stage 2: migration at the direction of the instructional design librarian (idl), research guide editors at uhl revised and prepared their own guide content throughout fall 2015, eliminating unneeded information and reorganizing what remained. the idl led multiple trainings and work sessions throughout the process to ensure compliance. during this same time, the idl completed back-end work in the libguides system to prepare for migration, and the web services department created a custom layout for the new guide site. the data migration itself took place on december 18, 2015, followed by cleanup and full implementation in january 2016. the idl provided a deadline by which all content must be ready for public consumption, prior to the start of the spring semester. af ter that deadline, the web services department switched the url for uhl’s research guides site to the libguides v2 instance and made the new system publicly available. stage 3: face-to-face testing after the migration process was complete, the idl assembled a team of ten other librarian and staff stakeholders from the liaison services, special collections, and web services departments to develop a usability testing protocol. this team assisted the idl in developing two different face-toface testing scripts and the text of a survey for distance users, as well as helping to administer face-to-face testing. the method we chose for the face-to-face testing process was think-aloud testing. in a think-aloud test, the user is provided a set of tasks to complete using the web resource that have been identified as common potential uses. the user is asked to attempt each task, and to narrate any thoughts or reactions to the resource, as well as the thought process and rationale behind each decision made. information technology and libraries | december 2019 80 several members of the team were already familiar with usability practices and had participated in think-aloud user testing before. training for the others was provided in the form of short practical readings, verbal guidance from the idl in group meetings, and practice sessions before conducting the face-to-face testing. in the practice sessions, group members volunteered for their roles in the testing, discussed protocol and logistics and asked any questions, and practiced the tasks they would each need to complete: making the recruitment pitch to users, walking through the consent process, using recording software, using the notetaking sheet, and so on. as the team leader and one of the members experienced with usability, the idl conducted the actual testing interviews. each of the face-to-face tests focused on either subject guides or the guide homepage. for both tests, tables were set up in the 24-hour lounge for recruitment and testing. two team members recruited students in the library at the time of testing by offering snacks and library branded giveaways. two additional team members facilitated the test and took notes during testing. both tests also used the same consent forms and demographic questions, and largely the same followup questions. participants in both homepage and subject guide testing were guided to the appropriate starting points and interviewed about their impressions of the homepage and guides, their perceptions of the purpose of these resources, and their understanding of the research guides name. subject guide testers were allowed to select which of our two testing guides they would be more comfortable using: the general business resources guide, or the biology and biochemistry resources guide. subject guide testers were also asked how they would seek help if the guide did not meet their needs. both groups were then asked to complete one of two sets of tasks. the homepage tasks were designed to test users’ ability to find individual guides, either for a specific course or for general information on a subject; the subject guide tasks were designed to test users’ ability to find appropriate resources for research on a given topic. after completing the tasks for their appropriate resources, participants answered several general follow-up questions, with additional questions from the facilitator as necessary. stage 4: survey unlike the face-to-face testing, the survey focused only on use of subject guides, not the homepage. otherwise, however, because the purpose of the survey was to compare the behavior of distance users to the behavior of on-campus users, the survey was designed to mimic the face-to-face test as closely as possible. several team members with liaison responsibilities identified distance user groups in their subject areas who would be demographically appropriate and available at the needed time, and contacted appropriate faculty members to ask for assistance in distributing the survey via email. ultimately, the survey was distributed to small cohorts of users in the areas of social work, education, nursing, and pharmacy, and customized for each targeted cohort. each version of the survey linked users to their appropriate subject guide and then asked the same questions regarding impressions of the guide that were asked in the face-to-face testing. users were also asked to complete tasks using the guide that were similar in purpose to those in the face-to-face testing, and they were prompted to enter the resource they found at the end of each task. demographic information was requested at the end of the survey to ensure that in the event of drop-offs, basic demographic information would be more likely to be lost than testing data. the testing for transition | lierman, scott, warren, and turner 81 https://doi.org/10.6017/ital.v38i4.11169 survey was distributed to the target groups over a three-week period in june 2016. six users at least partially completed the survey, and four completed it in full. stage 5: analyzing and implementing results after completing the face-to-face testing, the idl reviewed and transcribed the recordings of each test session, along with additional insights from the notetakers. responses to each interview question were coded and ordered from most to least common, as were patterns of behavior and difficulties in completing each task. task results and completion times were also recorded for each user and organized into a spreadsheet with users’ demographic information. the idl then reported out to research guide editors on common responses and task behaviors observed in the testing, and interpretations of the implications of these results for guide design. after survey responses were collected, the idl compiled and analyzed the results using a similar process, although the survey received few enough responses that coding was not necessary. users’ responses to questions were noted and grouped, and success and failure rates on tasks were tallied. a second report out to research guide editors summarized these results and described which responses closely resembled those received in the face-to-face testing and which varied. finally, when all data had been collected, the idl compiled recommendations based on the testing results with other recommendations derived from past uhl studies and from reviewing the literature, and from these developed a set of research guides usability guidelines. the guidelines were organized from highest to lowest priority, based on how commonly each was indicated in testing or in the literature. research guide editors were asked to revise their guides according to these guidelines within one year of their implementation, and advised that their compliance would be evaluated in an audit of all guide content in summer 2017. in the interest of transparency, the idl also included in the guidelines document an annotated bibliography of the relevant literature review, and a formal report on the procedures and results of the usability testing process. findings card sort one significant observation from the card sort was that, while librarians tended to organize guides into groups based on type of user (e.g., “undergraduates,” “student athletes,” “first-years,” etc.), none of the students who participated categorized resources in this way, and they did not seem to be particularly conscious of the categories into which they or other users might fit. instead, their groupings focused on the type of task to which each guide would be most appropriate, rather than the type of user that would be most likely to use that guide. for example, users readily recognized guides related to citation tasks and preferred them to be grouped together, regardless of the level at which they addressed the topic, and also grouped advanced visualization techniques like gis with simpler multimedia-related tasks like finding images. similarly, category labels tended to include “how to . . . ” language in describing their contents, focusing on the task to which the guides in that category would be beneficial. this aligns with the recommendation from sinkinson et al. to name guide pages based on purpose rather than format.18 it is worth noting, however, that all of the students who participated in the card-sort study were undergraduates and may not have fully understood some of the more complex research tasks being described. it should also be noted that all users created some sort of category for “general” or “basic” research tasks, and most either explicitly created an “advanced” research category, or information technology and libraries | december 2019 82 created several more granular categories and then verbally described these as being for “advanced” research tasks. in general, organization by task type was most preferred, followed by level of sophistication of task. face-to-face testing: homepage no significant correlations were found between user demographics and users’ success rates in completing each task, nor between demographics and time on task. users’ ability to navigate the system was generally consistent regardless of major, year in program, and—somewhat surprisingly—frequency of library use. this is, however, in keeping with costello et al.‘s finding that technology barriers were more significant in user testing than level of experience.19 when testing the homepage, we found that all users were able to find known guides (such as a course guide for a specific course) and appropriate guides for a given task (such as a citation guide for a particular style) quickly and easily. when seeking a guide, users generally used the by subject view of all guides to locate both subject and course guides. if this view was not helpful, as in the case of citation style guides, users’ next step was most commonly to switch to the all guides view and use the search function to look for key terms. users understood and used the by subject and all guides views intuitively, expressed more confusion and hesitation about the by owner and by type views, and disregarded the by group view entirely. we had been concerned about whether the search function would confuse users by highlighting results from guide subpages, but on the contrary, the study participants used the search function easily, and the fact that it surfaced results from within guides seemed to help them find and identify relevant terms, rather than confusing them. overall, users responded favorably to the look and feel of guides, albeit with a few specific critiques: the initially limited color palette made it difficult for some users to distin guish parts of a guide from one another, and the text size was found to be uncomfortably small in some areas. face-to-face testing: subject guides in subject guide testing, we found overwhelmingly that users both valued and made use of link and box descriptions within guides, using them throughout the navigation process as sources of additional information. users generally preferred briefer descriptions, rather than reading lengthy paragraphs of text, but several noted specific instances in which they would not have understood the nature or purpose of a database without the description that was provided. we also found, conversely, that librarian profile boxes were of less value to users than we had assumed. when asked how they would find help when researching, most subject guide testers said they would turn to google, ask at the library service desk, or use the contact us link in the libguides footer; only two mentioned the profile box as a potential source of help at all. users also seemed unsure of the purpose of the profile box, and not to recognize whose photo and contact information they were seeing, in spite of box labels and text. contrary to our expectations, users also readily clicked through to subpages of guides to find information, sometimes even when more useful information was actually available on the guide landing page. this was particularly evident in one of the subject guides that included internal navigation links in a box on the landing page: if users saw a term they recognized in one of these links, they would click it immediately, without exploring the rest of the page. in general, users latched on quickly to terms in subpage and box titles that seemed relevant to their tasks, and some expressed feelings of increased confidence and reassurance when seeing a familiar term featured testing for transition | lierman, scott, warren, and turner 83 https://doi.org/10.6017/ital.v38i4.11169 prominently on an otherwise unfamiliar resource. scanning for keywords in this manner also sometimes led users astray, however: some navigated to inappropriate pages or links because they featured words like “research” or “library” in their titles. users also expressed confusion about page titles that did not match their expectations of tasks they could complete online, such as “biology reading room.” these findings support those of many prior authors regarding the importance of including clear descriptions with key words that users readily understand.20 many of our results from subject guide testing not only ran counter to our expectations, but challenged the assumptions on which we had based our questioning. for example, we had been curious to learn whether links to external websites were used significantly compared to links to library databases, or if they simply cluttered guides unnecessarily. in testing, however, we found that users did not distinguish between the two types of resources at all, and used both interchangeably. a better question seemed to be not whether users found those links useful, but how to distinguish them from library content—or whether the distinction was necessary from the user’s perspective. some team members had also been concerned about the scroll depth of guide pages, but the majority of users not only said they did not mind scrolling, but seemed surprised and amused by being asked. their own assumptions about this type of resource clearly included the need to scroll down a page. a few other miscellaneous issues presented themselves in our face-to-face testing. one was that the purpose and nature of research guides was not readily evident to users. many used language that conflated guides with search tools like databases, or even with individual information resources like books or articles. for example, a user asked whether the by owner view listed the authors of articles available in this resource. the curated and directional nature of research guides was not at all clear to users. furthermore, in spite of the improvements to guide look and feel in libguides v2, several users still spoke of guides as being cluttered, lengthy, and overwhelming, leaving them intimidated and unsure of where to begin. consistently, testers tended to gravitate toward course guides even when subject guides would have been more appropriate for a given task, and some users expressed that this choice was because of the greater specificity in course guide titles. users demonstrated a great preference for familiarity, gravitating toward terms and resources that were known to them, and even repeating behaviors that had been unproductive earlier in the testing process. finally, one of the greatest points of confusion for users seemed to be the relationship of research guides to physical materials within the library. users readily and confidently followed links to online resources from research guides but expressed confusion and hesitancy when guides pointed to books or other resources available in the library. survey the survey of off-campus users had few responses, but the demographics of the respondents varied more than those of the on-campus testing participants, including graduate students and faculty. the users who did respond showed evidence of less use of guide subpages than we had observed in the face-to-face testing, indicating that the presence of a librarian during testing may have influenced users to explore guides more thoroughly than they would have when working on their own. at the same time, more experienced researchers in the survey group—in this case, a late-program graduate student and a faculty member—were apparently more likely than less experienced users to explore guides thoroughly, and to succeed at research tasks. survey respondents also were far more likely to state that they would use the profile box on guides for information technology and libraries | december 2019 84 help, with some indicating that they recognized their liaison librarian’s picture and were familiar with the librarian as a source of assistance. liaison librarians at uhl often work more closely with higher-level students and faculty than with undergraduates, and this greater familiarity was not surprising. discussion implementation of findings based on the results of the literature review and testing, a number of changes and recommendations were implemented. a brief description of the nature and purpose of research guides was added to the guide homepage’s sidebar, and more color variation was added to guides, while font sizes were increased. existing documentation was also reworked and expanded to create the research guides usability guidelines document for all guide editors, which included adding or revising the following recommendations: • pages, boxes, and resources should all be labeled with clear, jargon-free language that includes keywords familiar to their most frequent users. • page design should be “clean and simple,” minimizing text and incorporating ample white space. • brief, oneto two-sentence descriptions should be provided for all links. • each guide should have an introduction on its landing page with a brief description of its contents and purpose. it may be helpful to include links to subpages in this box as well, but this should be done judiciously, as these links may take users off the landing page prematurely. • pages and resources aimed at undergraduates should be organized and titled according to their relevance to research tasks (e.g., “find articles”), and not by user group. • electronic resources should be prioritized on guides over print resources. • clear distinctions should be made between library and non-library links when the distinction is important. • a profile box with a picture should be included, but the importance of this item is not as great as we had previously imagined. limitations one of the most significant challenges in our testing was actually negotiating the irb application process. delays in our application raised concerns within the team that we would not receive approval in time to test with students before the start of the summer break. although we did receive approval in time, the window for testing afterward was extremely narrow. submitting the application also bound us to the scripts and text that we had originally drafted, which severely limited the flexibility of the testing process. this became a challenge at several points when a particular phrasing or design of a question was found to be ineffective in practice, but could not be altered from its original form. tensions between the requirements for institutional review and the unique needs of usability testing are a persistent problem for user experience development in an academic setting, and must be planned for accordingly as much as possible. in some cases, as well, we might have improved our results by better designing our questions. one example of this was the question about the name “research guides,” which anecdotal evidence has suggested might be challenging for users. simply asking whether that name made sense to the participant was clearly not effective in practice, and did not yield actionable insights. in the future, testing for transition | lierman, scott, warren, and turner 85 https://doi.org/10.6017/ital.v38i4.11169 we might consider informal testing of our planned questions with users in the target demographic before proceeding with full-scale usability testing. a final challenge was in gathering data on use of guides by distance users. though we were able to get enough responses to draw some tentative conclusions, we had hoped for a larger pool of data. though it would make the results more difficult to compare to in-person testing, reducing the length of the survey might have helped to produce more responses. additionally, increased marketing and more flexible timing for survey distribution might have also helped us reach a larger audience. conclusions the results of our testing were very instructive, and led to the creation of valuable documentation for guide editors to use in their work. we also learned a number of lessons relating to process that would be of value to other librarians seeking to perform similar testing at their own institutions. the first of these is that working with a large, interdepartmental team on this type of project— while occasionally unwieldy—is greatly beneficial overall. even if all the team members are not able to fully participate, involving as many colleagues as possible in the usability testing process lessens the workload for each individual, increases flexibility, and ultimately increases buy-in and compliance with the resulting changes and recommendations. for a platform used directly by a relatively large percentage of librarians, as libguides generally is, the number of stakeholders in user research is correspondingly large, and as many of these stakeholders as possible should be involved to some degree. not only will this distribute the benefits of the process more broadly, it will make it possible to staff more extensive and more frequent testing sessions. in the course of our testing process, we also came to recognize the value of testers familiar with the user group under examination. a majority of librarians involved in testing were from publicfacing departments, with significant student contact in their day-to-day work. as a result, we were able to quickly attract a diverse set of participants for our testing simply through our collective knowledge of students’ likely behaviors and preferences: where students were most likely to congregate, what kinds of rewards would motivate them to participate, how to reach them at a distance, and how far their patience would be likely to extend for an in-person interview or an online survey. the incentives and location that the testing teams selected were so effective that the numbers of volunteers we received overwhelmed our capacity to accommodate within the allotted testing time, resulting in a substantial pool of responses for analysis. therefore, we conclude that the effectiveness of user research can be increased by including (or at least consulting) those most familiar with the user group to be studied. simply assuming that participants will be available may ultimately compromise the effectiveness of testing. additionally, time management is an extremely important element of testing development. failing to fully account for the demands of the irb process, for example, led to significant limitations for our project concerning the timing of testing, the availability of participants, our capacity for marketing and distribution of the survey, and the quality of our testing instrument. while acknowledging that, as in our case, sometimes the need for usability testing arises on short notice, we recommend allocating as much time and preparation to the process as possible, to ensure that every aspect of the testing can be given adequate attention. information technology and libraries | december 2019 86 figure 1. average monthly guide views by transition period. testing for transition | lierman, scott, warren, and turner 87 https://doi.org/10.6017/ital.v38i4.11169 as a final note, nearly two years after the best practices were implemented, we collected and compared guide traffic statistics from three key periods: • september 2014 through december 2015, the sixteen months preceding our transition to libguides v2; • january 2016 through august 2017, our first twenty months on libguides v2, during which time best practices had not yet been fully developed and implemented; and • september 2017 through april 2019, from the beginning of best practices implementation through the time of writing (best practices were implemented gradually between september 2017 and february 2018). mindful of the fact that guide usage fluctuates with the academic year, we compared average views for each guide on a monthly basis. figure 1 shows the average number of times each guide was viewed in a month for each period of the transition. as the figure shows, for most of the academic year, guide views dropped sharply after our transition from libguides v1 to libguides v2, and continued to decline slightly with time through the period when our best practices were implemented. there are a number of possible causes for this phenomenon: • guide usage may be declining over time generally for a variety of reasons, and the transition to the new look of v2 may have confused and disoriented users in the immediate aftermath, causing use of some guides to be discontinued. • a substantial number of older guides were eliminated in the transition to v2, some of which may have been more heavily used than suspected, and new guides that have been created since may not yet have gained traction and recognition from users. • librarians may also have reduced their efforts to incorporate guides into their teaching and outreach strategies. • improved organization in the new system may be helping users to find the guide they need on the first try, without having to move through and examine multiple guides. in any case, this trend is concerning and merits further investigation, but a direct correlation with the transition to libguides v2 and the implementation of best practices has not been established. a more accurate measure of the effect of the best practices would be a user satisfaction survey, although a comparison would be difficult to make due to a lack of a baseline from bef ore the transition. we will continue to investigate trends in the use of our guide and how our best practices have affected our users, and how they can be improved upon in the future. information

tonia san nicolas-rocca (tonia.sannicolas-rocca@sjsu.edu) is assistant professor in the school of information at san jose state university. richard j. burkhard (richard.burkhard@sjsu.edu) is professor in the school of information systems and technology in the college of business at san jose state university. . author three (email) is title, institution. abstract libraries in the united states handle sensitive patron information, including personally identifiable information and circulation records. with libraries providing services to millions of patrons across the u.s., it is important that they understand the importance of patron privacy and how to protect it. this study investigates how knowledge transferred within an online cybersecurity education affects library employee information security practices. the results of this study suggest that knowledge transfer does have a positive effect on library employee information security and risk management practices. introduction libraries across the u.s. provide a wide range of services and resources to society. libraries of all types are viewed as important parts of their communities, offering a place for research, to learn about technology, to access accurate and unbiased information, and a place that inspires and sparks creativity. as a result, there were over 171 million registered public library users in the u.s. in 2016.1 a library is a collection of information resources and services made available to the community in which it serves. the american library association (ala) affirms the ethical imperative to provide unrestricted access to information and to guard against impediments to open inquiry.2 further, in all areas of librarianship, best practice leaves the library user in control of as many choices as possible.3 in a library, the right to privacy is the right to open inquiry without having the subject of one’s interest examined or scrutinized by others.4 many library resources require the use of a library card. to obtain a library card in the u.s. one must provide official photo identification showing personally identifiable information (pii), such as name, address, telephone number, and email address. pii connects library users or patrons with, for example, items checked out, and websites visited. as such, pii has the potential to build up an image of a library patron that could potentially be used to assess the patron’s character. in response, the ala developed a policy concerning the confidentiality of pii about library users.5 confidentiality extends to “information sought or received and resources consulted, borrowed, acquired or transmitted,” and includes, but is not limited to, database search records, reference interviews, circulation records, interlibrary loan records, and other personally identifiable uses of library materials, facilities, or services.6 in more recent years, the ala has further specified that the right of patrons to privacy applies to any information that can link “choices of taste, interest, or research with an individual.”7 when library users recognize or fear that their privacy or information technology and libraries | june 2019 59 confidentiality is compromised, true freedom of inquiry no longer exists. therefore, it is imperative that libraries use extra care when handling patron personally identifiable information. while librarians and other library employees may understand the importance of data protection, they generally don’t have the resources available to assess information security risk, employ risk mitigation strategies, or offer security education, training, or awareness (seta) programs. this is of particular concern as libraries increasingly have access to databases of both proprietary and personal information.8 seta programs are risk mitigation strategies employed by organizations worldwide to increase and maintain end-user compliance of information security and privacy policies. in libraries, information systems are widely used to provide services to patrons, however, there is little known about information security practices in libraries.9 given the sensitivity of the data libraries handle, and the lack of information security resources available to them, it is important for those currently or planning to work in the library environment to develop the knowledge necessary to identify risks and develop and employ risk mitigation strategies to protect information and information resources they are entrusted with. therefore, the research question in this present study is: how can cybersecurity education strengthen information security practices in libraries? currently, there is a dearth of research on information security practices in libraries.10 this is an important research gap to acknowledge given that patron privacy is fundamental to the practice of librarianship in the u.s, and the advancement in technology coupled with federal regulations adds to the challenges of keeping patron privacy safe.11 thus this study contributes to current literature by evaluating the effects of knowledge transfer as a means to strengthen information security within libraries. furthermore, this study will offer a preliminary investigation as to whether knowledge utilization leads to motivation and the participation of information security risk management activities within libraries. the remainder of this paper proceeds as follows: first, a review of knowledge transfer is covered. a description of the cybersecurity course, including students and course material, is provided. data collection and analysis are then presented. this is followed by a discussion of the findings, limitations, and future research. literature rivew knowledge transfer in seta knowledge transfer through seta programs plays a key role in the development and implementation of cybersecurity practices.12 knowledge is transferred when learning takes place and when the recipient of that knowledge understands the intricacies and implications associated with that knowledge so that he or she can apply it.13 for example, in a security education program, an educator may transfer knowledge about information security risks to users who learn and apply the knowledge to increase patron privacy. the knowledge is applied when evidenced by users who are able to identify risks to patron data and implement risk mitigations strategies that serve to protect patron information and information system assets. knowledge transfer can be influenced by four factors: absorptive capacity, communication, motivation, and user participation.14 this study evaluates the extent to which knowledge transferred from a cybersecurity course strengthens information security practices within libraries. this study adapts the theoretical model as proposed by spears & san nicolas-rocca information security in libraries | san-nicolas-rocca and burkhard 60 https://doi.org/10.6017/ital.v38i2.10973 (2015) (see figure 1) to examine the effects of cybersecurity education on information security practices in libraries.15 figure 1. factors of knowledge transfer leads to knowledge utilization. absorptive capacity absorptive capacity is the ability of a recipient to recognize the importance and value of eternally sourced knowledge, assimilate and apply it and has been found to be positively related to knowledge transfer.16 activating a student’s prior knowledge could enhance their ability to process new information.17 that is, knowledge transfer is more likely to take place between the instructor and students enrolled in a cybersecurity course if the student has existing knowledge or has had experience in some related area. for the present study, students have stated that prior to enrolling in the cybersecurity course, they had little to no knowledge of cybersecurity. one student mentioned, “while i am the director of a small academic library, i have no understanding of cybersecurity. i am taking this course to learn about cybersecurity so that i can better secure the library i work in and to share the information with those who work in the library.” another student mentioned, “my goal is to work in a public library after graduation. i am taking this course because i keep hearing about cybersecurity breaches in the news, and i want to learn more about cybersecurity because i think it will help me in my future job.” while all of the students enrolled in the course had no cybersecurity experience, all of them had some understanding of principle 3 in the ala code of ethics, which states, “we protect each library user’s right to privacy and confidentiality with respect to information sought or received and resources consulted, borrowed, acquired or transmitted.”18 understanding of principle 3 in the code of ethics demonstrates existing knowledge in some related area with regards to cybersecurity, albeit limited knowledge. given this understanding, students should have the ability to process new information from the cybersecurity course. information technology and libraries | june 2019 61 communication the success of any seta program depends on the ability of the instructor to effectively communicate the applicability and practical purpose of the material to be mastered, as distinguished from abstract or conceptual learning.19 according to current research, knowledge transfer can only occur if communication is effective in terms of type, amount, competence, and usefulness.20 for the present study, students were enrolled in an online graduate level cybersecurity course at a university we call mountain view university (mvu). we changed the name to protect the privacy of the research participants. while research suggests that the best form of communication for knowledge transfer is face-to-face communication, the cybersecurity course at mvu is only offered online.21 therefore, communication relating to the course was conducted via course management software, email, video conferencing, discussion board, and prerecorded videos. motivation motivation can be a significant influence on knowledge transfer.22 that is, an individual’s motivation to participate in seta programs has been found to influence the extent to which knowledge is transferred.23 specifically, without motivation, a trainee may fail to use information shared with them about methods used to protect and safeguard patron privacy. in this present study, research participants voluntarily enrolled in the cybersecurity course. the cybersecurity course is not a core course or a class required for graduation. therefore, enrolling in the course implies motivation to learn about cybersecurity by participating in course activities and completing assigned work. user participation user participation in information security activities may influence effective knowledge transfer initiatives.24 according to previous research, when users participate in cybersecurity activities, security safeguards were more aligned with organizational objectives and were more effectively designed and performed within the organization.25 for the present study, given that students enrolled in the cybersecurity course, it is expected that they will participate in information security risk management activities, such as the completion of personal and organizational risk management projects. cybersecurity course information this study will examine whether cybersecurity education strengthens information security practices within libraries. based on the model in figure 1, students enrolled in the cybersecurity course (motivation), and therefore, were expected to participate in all course activities and complete assigned work (user participation), such as isrm assignments. isrm assignments are described in the course material section below. as per figure 2, the cybersecurity course was offered online, and used multiple forms of communication, including email, video conferencing, discussion board, and pre-recorded videos (communication). students were able to access these resources through canvas, a learning management system. students came into the class with some understanding of principle 3 in the ala code of ethics. therefore, given that this knowledge is in a “related area,” students may be able to process new information relating to cybersecurity (absorptive capacity). as per the above information and as depicted in figure 1, motivation, user participation, communication, and absorptive capacity will lead to knowledge transfer. therefore, this study will focus on how knowledge transfer, as a means to strengthen information security, leads to knowledge utilization by cybersecurity students within information organizations. information security in libraries | san-nicolas-rocca and burkhard 62 https://doi.org/10.6017/ital.v38i2.10973 specifically, this study will explore the possibility of knowledge utilization leading to motivation, and participation in isrm initiatives in libraries. figure 2. knowledge transfer elements: cybersecurity knowledge transfer for information organizations. course material the course was offered to graduate students at mountain view university. course material was created based on the national institute of technology special publication (nist sp) 800-53 and 60, as well as federal information processing standards (fips) publications 199 and 200. the focus of the course was information security risk management (isrm). course requirements included lab exercises, discussion posts relating to current cybersecurity findings and news reports, and isrm assignments. isrm assignments included a personal risk management assignment, which then led to the completion of an organizational risk management project (ormp). students completed the ormp for various libraries, healthcare institutions, pharmaceutical companies, government organizations, and small businesses. with instructor approval, students were allowed to select the organization they wanted to work with. the objective of the course was for students to obtain an understanding of isrm and be able to apply what they have learned to the workplace. course communication seta programs depend strongly on the ability of the knowledge source to effectively communicate the importance and applicability of the knowledge shared. current research suggests that the type of communication medium, relevance and usefulness of the information, and competency of the instructor can affect knowledge transfer. given that face-to-face communication is considered the best method for successful knowledge transfer, it is important to understand if online communication methods were effective in the cybersecurity course described herein as the main focus of this study is to determine if knowledge transfer leads to knowledge utilization. according to table 1, respondents “strongly agree” or “agree” that the materials used, relevance of communication, comprehension of instructor communication, and the amount of time communicating about cybersecurity in the course was effective (data collection described in section, data collection and analysis. information technology and libraries | june 2019 63 questions

cybersecurity education, as a means to strengthen information security, leads to knowledge utilization within libraries. specifically, this study will examine if research participants will engage in isrm activities after completion of the cybersecurity education course. the model in figure 1 is examined via survey instrument by the authors. the survey instrument was available to former students who completed an online, semester long, cybersecurity course from fall 2013 through fall 2017. one hundred and twenty-six former students completed one of eight cybersecurity courses, and all were asked to participate in this study. thirty-nine students accessed the survey, but only thirty-eight agreed to participate. of those who agreed to participate in the survey, only twenty-two work in a library in the u.s. or a u.s. territory. of the other sixteen participants, twelve do not currently work within a library environment, and four do not have a job. therefore, responses from twenty-two research participants who work in a library in the u.s. or u.s. territory will be reported in this study. table 2 provides a list of the types of libraries the twenty-two research participants work

extent to which the cybersecurity student acquired knowledge or understands the key educational objective. according to table 4 below, all survey participants stated that during the cybersecurity course, they acquired knowledge on information security risks, and solutions to manage information security risks within organizations. furthermore, 91 percent of the twenty-two survey participants stated that they gained an understanding of the feasibility to implement solutions and potential impact of not implementing solutions to manage information security risk within the organizations in which they work. this is consistent with previous research that has measured knowledge transfer.26 question: during the cybersecurity course i took at mvu, i _________. response acquired knowledge on

management initiatives in their workplace since the completion of the cybersecurity course. according to table 5, twelve of the twenty-two survey participants have utilized the knowledge transferred to them from the cybersecurity course within the libraries in which they work. of the twelve survey participants, ten performed security procedures within the organization on an ad hoc, informal basis. seven worked on defining new or revised security policies. four implemented new or revised security procedures for organizational staff to follow, and two evaluated at least one security

discussion the purpose of this study was to evaluate the effects of knowledge transfer as a means to strengthen information security within libraries. given the results from the survey instrument, the findings suggest that knowledge transfer through cybersecurity education can lead to knowledge utilization. specifically, knowledge transfer through cybersecurity education may influence a library employee to utilize the knowledge they have gained by participating in discussions about, and the accountability and responsibility of isrm activities. in addition, participating in seta programs. seta programs are implemented within organizations as a means to increase compliance of information security policies. the findings suggest that library employees who completed a cybersecurity education course believe that it is important to, or feel that they have a responsibility to, protect patron private information. a couple of research participants stated that they would feel embarrassed if their organization experienced a data breach. a student enrolled in a cybersecurity education course may develop an understanding of and value the information that is passed on from the knowledge source about isrm activities. with ongoing development and implementation of seta programs, activating a student’s prior knowledge of isrm activities could enhance their ability to process new information and apply to their job. limitations and future research this research was conducted based on an online cybersecurity course offered at a university located in the western u.s. therefore, future research is needed to study how cybersecurity courses in other parts of the u.s and internationally affects knowledge transfer as a means to strengthen isrm initiatives in libraries, and other information organizations. it would also be valuable to conduct a modified version of this research within a classroom-based, face-to-face cybersecurity course. furthermore, seta programs implemented in libraries in the united states and internationally would add to this research area. there were 126 potential research participants identified, and although all were asked to participate, only thirty-eight completed the online survey. of the thirty-eight completed surveys, responses from twenty-two participants were reported in this article. participation from additional research participants may have generated different results. information security in libraries | san-nicolas-rocca and burkhard 68 https://doi.org/10.6017/ital.v38i2.10973 while a major limitation of this study is its small pilot study and exploratory focus, a next phase of research should further investigate what type of seta programs would be most effective in different library environments. while cybersecurity education may not be feasible for all library employees to obtain, examining and implementing the most effective seta program for each library environment could strengthen cybersecurity practices in libraries across the u.s. a future study instrument should take into account the factors that influence knowledge transfer (absorptive capacity, communication, motivation, and user participation) as a means to strengthen isrm practices. a common an important outcome for seta programs is user compliance to information security policies. as such, a future study should test library employee knowledge of, and compliance to, information security policies. conclusion u.s. libraries handle sensitive patron information, including personally identifiable information and circulation records. with libraries providing services to millions of patrons across the united states, it is important that they understand the importance of patron privacy and how to protect it. this study investigated how knowledge transferred within an online cybersecurity education course as a means to strengthen information security risk management affects library employee information security practices. the results of this study suggest that knowledge transfer does have a positive effect on library employee information security and risk management practices. references 1 “public

information technology and libraries | march 2019 8 thomas finley (tfinley@friscotexas.gov) is adult services manager, frisco public library. chances are that before you read this article, you probably checked your email, used a mapping app to find your way, or typed a search term online. without your even perceiving it, artificial intelligence (ai) has already helped you to accomplish something today. email spam filters use variants of ai to help cut down on harmful or useless emails in your inbox.1 with ai doing the factcrunching, mapping apps quickly preview the best route based on a myriad of factors. search engine companies like google have been using ai to suggest or produce results faster for longer than anyone outside of the company really knew until recently.2 according to a recent study by northeastern university and gallup, 85% of americans are already using ai products.3 the true revelation behind these recent technological developments may not be the fact that ai is already embedded into the fabric of our modern lives. the real surprise might just be the sudden ubiquitous availability (and approachability) of ai tools for all. as google’s former chief scientist of ai and machine learning, fei-fei li, said in 2017, “the next step for ai must be democratization, lowering the barriers of entry, and making it available to the largest possible community of developers, users and enterprises."4 this sounds a lot like most public libraries’ mission statements. as with other important workforce development efforts, libraries are uniquely placed to participate in this new revolution as key platforms for the discovery and dissemination of emerging tech knowledge. at the frisco public library (https://www.friscolibrary.com), we saw this ai trend surfacing, we see ai as a critical future job skill, and we investigated ways to introduce our patrons into this space. as such, the frisco public library has leveraged readily available technology in a cost-effective way that has engaged community interest. our efforts are also replicable and scalable in terms of multi-nodal experiences both at home and in classroombased learning. some basic definitions let’s take a few steps back to give some broad definitions and boundaries to the scope of ai. according to the oxford english dictionary, artificial intelligence is “the capacity of computers or other machines to exhibit or simulate intelligent behavior.”5 in the literature, you will find a further distinction between general ai, narrow ai, and something called machine learning.6 general ai is something that begins to look like science fiction: an artificial intelligence that learns how to learn, then is able to generalize what it has learned and apply that knowledge to a different case. in advanced examples of general ai, scientists are thinking of not putting a specific problem in front of a general ai program to solve, rather, they are giving it an entire dataset so the program itself can choose what problems it should work on. removing the limited point of view of whoever programs the program.7 narrow ai is easier to understand because it is what we interact with the most in our day-to-day lives. it is what powers those little speed ups that help us do things faster every day: search information technology and libraries | march 2019 9 through our emails to help us avoid spam, translate speech to text when we dictate a message on a smartphone, or helps to parallel park a car at the touch of a button. narrow ai accomplishes a specific task extremely fast and accurately, and thus, becomes an extension and multiplier of our own human productivity. a lot of these narrow ai activities are based in a type of artificial intelligence called machine learning (ml). ml is a set of very complex processes that can review large sets of information; create and train models based on this data; make predictions of what will happen next; and then to refine that data for better future results.8 machine learning is the focus of our efforts at the frisco public library due to two main reasons: 1) it is what has been made available through free tools such as google’s open ai resources; and 2) it makes ai attainable in a library setting. our approach: makerspaces for everyone, at home the frisco public library has had 4 years of success with circulating makerspace technology in reasonably-priced, hard shell waterproof boxes with foam inserts. each kit is cataloged, rfid tagged, security tagged, and sealed with zip ties to enable self-checkouts (zip ties can be easily cut open at home, but prevent items from disappearing in the library). these cases are easy to handle and can take some abuse while protecting their contents. this is important because we circulate about 20 different kinds of robotics kits, no-soldering circuitry kits, 3d scanning kits, programing kits, and internet of things kits. most kits contain the theme item with quick start guides, instruction booklets, and a book to inspire advanced learning. we call these maker kits, and we have about 150 total. in our community, they are wildly popular and have circulated more than 4,000 times since their introduction in january 2016.9 aiy: artificial intelligence kits for everyone in 2017, google released their maker-focused aiy voice project kit (where aiy is a catchy substitute for do-it-yourself with artificial intelligence yourself). the kit consists of several components that pairs a raspberry pi (entry-level computer) and a small speaker that is housed in a cardboard box with a button prominently placed on top.10 the result is a stripped-down version of an amazon echo or google home device — essentially a smart speaker. although the aiy voice kit is not necessarily initially set up to play music, it is designed to take voice commands like the other products on the market. with a minimum of python coding expertise, aiy kits enable mass participation in artificial intelligence. there isn’t even any soldering required to put this kit together! this is 100% in line with fei-fei li’s (google’s former chief scientist for ai and ml) remarks about the need to democratize ai. google has since released another kit called aiy vision that uses similar components paired with a camera. more information on the kits can be found at https://aiyprojects.withgoogle.com/. frisco public library’s artificial intelligence maker kits based on our previous experience with other maker kits, we made a few modifications to the original google design that most librarians with access to a 3d printer can accomplish. the original aiy voice kit uses a punch-out cardboard box to fold and envelop the device. apart from being an extremely cost-effective way of making a box, it also seems like there is delicious irony (and message) in the contrasting of cardboard-as a cheap, widely available material-with the advanced tech of ai. durability being our priority, we knew we needed to upgrade this aspect of google’s original design. our maker librarian, adam lamprecht, quickly found a shared design file public libraries leading the way: the democratization of artificial intelligence 10 https://doi.org/10.6017/ital.v38i1.10974 uploaded to the website, www.thingiverse.com, that he modified to better suit our needs (see figure 1).11 figure 1. ai maker kits with 3d printed aiy voice device. we then printed these in a variety of colors on our 3d printers and modified the grid-patterned foam inserts to make room for the device and a few other items (see figure 2). we are currently circulating 21 of these kits without major incident. information technology and libraries | march 2019 11 figure 2. interior view of the kits. library instruction: python as a window onto artificial intelligence our basic artificial intelligence classes have been key in the introduction of this technology to the public. we reserve 10 kits for a class and pair them with classroom laptops for ease of use. the structure of the class provides a short introduction to the technology and then walks participants through a basic voice recognition coding challenge. all of this is accomplished in python. python is great for beginning coders because it is easier to learn than other programming languages, takes less time to write lines of code, and it can telescope up into a very large number of projects and applications.12 in fact, according to neal ford, director and software architect at thoughtworks, python, “is very good at solving bigger kinds of problems.”13 so with python, a beginning learner has a programming language that continues to be useful beyond the classroom and into the world of work or school. python provides another important advantage: “python provides the front-end method of how to hook into google’s open ai,” states tech writer sardar yegulalp.14 it is this combination of a free, accessible coding language with the powerful (and also free) resources of google’s open ai that truly lowers the barrier to entry for anyone interested in a hands-on experience with artificial intelligence. public libraries leading the way: the democratization of artificial intelligence 12 https://doi.org/10.6017/ital.v38i1.10974 lessons learned the ai maker kits are, by far, our most complicated circulating kits. we are hearing back from patrons that the kits are right on the mark. our users get it, they see the power in getting access to these ai tools (utilizing python) and by all accounts thus far, are happy with their results. there has been a perception gap between library staff, however, and what an ai kit can reasonably accomplish. adam lamprecht reports, “staff members had the expectation that perhaps with this kit, a rookie coder was going to be able to jump directly into developing deep learning neural networks (a very advanced subset of artificial intelligence) and so we definitely benefited from ongoing discussions of those broad ai terms and expectations.”15 google’s aiy voice is a good start but there is lots of room to grow ai classes for more depth. aiy vision is the next logical step that would allow us to enter into the world of basic image recognition. our approach does rely on one company’s platform, but there are more platforms to explore ai now. one of which is amazon’s offerings of machine learning on aws (amazon web services). these services have recently been opened up for a wider audience and amazon is now offering everyone the same online courses they use to train their own engineers.16 the aws ml resources are currently behind paywalls but access to the training alone could be powerful for the right learner. there are even interesting developments for younger learners in ai with robotics. anki (www.anki.com) is a consumer robotics company that uses ai to enliven its products. they released vector in 2018: a seemingly simple toy that responds to its environment and simple commands with the aid of ai. with the release of their software development kit the company is allowing others under the hood of their robots-which potentially means an entry-point for autonomous (or semi-autonomous) robotic vehicle technology powered by ai. what is clear is that the world of ai is already upon us. public libraries are well positioned to help meet the challenge of developing the workforce of the nearand far future with ai classes being a vital tool. the doorway to artificial intelligence is now open, the only question that remains is this: do you step through it? references 1 cade metz, “google says its ai catches 99.9 percent of gmail spam,” wired. july 9, 2015,

methods and maturity of user experience (ux) practice in academic libraries. the authors apply qualitative content analysis and quantitative statistical analysis to a research dataset derived from a survey of ux practitioners. results reveal the type and extent of ux methods currently in use by practitioners in academic libraries. themes extracted from the survey responses also reveal a set of factors that influence the development of ux maturity. analysis and discussion focus on organizational characteristics that influence ux methods and maturity. the authors conclude by offering a library-focused maturity scale with recommended practices for advancing ux maturity in academic libraries. introduction user experience (ux) is a design practice for creating tools and services from a user-centered perspective. academic libraries have been practicing ux for some time, with ux methods having been incorporated across the profession. however, there has been a lack of empirical data showing the extent of ux methods in use or state of ux maturity in libraries. to help illuminate these areas, we distributed a survey to ux practitioners working in academic libraries that inquired into methods and maturity. we followed a mixed-methods approach involving both qualitative content analysis and quantitative statistical analysis to analyze the dataset. our results reveal the mostand least-common ux methods currently in use in academic libraries. results also demonstrate specific organizational characteristics that help and hinder ux maturity. we conclude by offering a set of strategies for reaching higher levels of ux maturity. background and motivation: ux in academic libraries ux has been represented in the literature of library and information science for at least two decades, when “the human interaction involved in service use” was recognized as a factor affecting the value and impact of libraries.1 the practice of ux has expanded and evolved and is now a growing specialty in the librarianship profession.2 ux in libraries is motivated by a call to actively pay close attention to users’ unique and distinctive requirements, which allows libraries to more effectively design services for our communities.3 as a practice, ux is now beginning to be represented in graduate curricula, public services and research support, access services, space design, and web design.4 with its attunement to a set of practices and principles, ux can be viewed as a research and design methodology similar and related to other methodologies that focus on users, services, problem solving, participation, collaboration, and qualitative data analysis .5 notably, ux is related to human-centered design, service design, and participatory design.6 mailto:swyoung@montana.edu mailto:chaoszuyu@gmail.com mailto:alc28@cornell.edu information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 2 specific methods of ux practice are today wide-ranging. they include surveys, focus groups, interviews, contextual inquiry, journey mapping, usability testing, personas, card sorting, a/b testing, ecology maps, observations, ethnography, prototyping, and blueprinting.7 some ux methods are incorporated into agile development processes.8 though tools and techniques are available to library ux practitioners in abundance, the rate of adoption of these tools is less understood. in a notable contribution to this question, pshock showed through a nation-wide survey that the most familiar ux methods among library practitioners included usability testing, surveys, and focus groups.9 the question of methods is related to the question of maturity—how advanced is library ux practice? in addition to the rate of adoption of methods and tools, several different ux maturity models have been advanced in recent years. priester derives maturity from four factors: culture of innovation, infrastructure agility, acceptance of failure, and library user focus.10 in discussing ux capacity in libraries, macdonald proposes a six-stage maturity model: unrecognized, recognized, considered, implemented, integrated, and institutionalized.11 sharon defines maturity as a combination of staff resources and organizational buy-in.12 similarly, sheldon-hess proposes a five-level scale of ux maturity, based primarily on the degree of implementation of ux practice and user-centered thinking in an organization.13 and even earlier, nielsen proposed an eight-level scale of ux maturity, starting with a “hostility toward usability” and concluding with a “userdriven” organization.14 after reviewing a number of different maturity models, anderson reports that the most common hierarchies include the following steps: (1) absence/unawareness of ux research, (2) ux research awareness—ad hoc research, (3) adoption of ux research into projects, (4) maturing of ux research into an organizational focus, (5) integrated ux research across strategy, and (6) complete ux research culture.15 the field of library ux shows a clear and compelling interest in ux maturity, and we can benefit from further empirical evidence that can help illuminate the current state and future progress toward ux maturity, including the rate of adoption of methods, resource allocation toward ux, and organizational buy-in. the research presented in this paper is motivated by the need to provide current and comprehensive data to answer questions related to ux maturity in academic libraries. methods research questions the research questions for this study are the following: • rq1: how mature is ux practice within academic libraries? • rq2: what factors influence ux maturity? to answer these questions, we distributed a survey to ux practitioners working in academic libraries. survey responses were analyzed qualitatively using content analysis and quantitatively using statistical analysis. survey participants the team members sent out the survey on may 23, 2018, to library profession electronic discussion lists.16 of the 87 received responses, 74 included an institution name. we identified size and setting classification using the carnegie classification of institutions of higher education (see information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 3 table 1) for the institutions.17 eight of them cannot be mapped to the carnegie classification due to being outside the united states (n = 6) or of different scopes (one research lab and one information school). six schools have more than one response, which are treated separately to represent the diversity of opinion and experience within an organization. classification response count percentage four-year, large 4918 56 four-year, medium 1019 11 university outside us 6 7 four-year, small 5 6 non-university 2 2 four-year, very small 1 1 two-year, very large 1 1 unspecified 13 15 table 1. institutional profiles of survey respondents, with response counts. materials and procedure our online survey was organized into two main parts. after an initial informed consent section, the survey investigated (1) demographics and ux methods and (2) ux maturity. demographics and ux methods in the first main part of the survey, participants were asked to select among 20 different ux methods that “you personally use at least every year or two at your institution.” the list of methods is derived from the ux research cheat sheet by nielsen norman group.20 participants were asked to complete an optional free-text response question: “would you like to add a comment clarifying the way you completed [this question]?” ux maturity in the second main part of the survey, participants were asked to identify the ux maturity stage that “properly describes the current ux status” in their organization. the stages were adapted from the eight-stage scale of ux maturity proposed by nielsen norman group: • stage 1: hostility toward usability • stage 2: developer-centered ux • stage 3: skunkworks ux • stage 4: dedicated ux budget • stage 5: managed usability • stage 6: systematic user-centered design process • stage 7: integrated user-centered design information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 4 • stage 8: user-driven organization we concluded the survey by asking participants to optionally “explain why you selected that stage” with a free-text response. research data analysis content analysis we followed the methodology of content analysis.21 each qualitative survey response functioned as a meaning unit, with meaning units sorted into themes and subthemes. each article author coded units independently; themes were resolved through discussion among the author group. the process of coding via content analysis allowed us to identify overarching trends in ux practice and maturity. results are further discussed below. statistical analysis data preparation and statistical analysis were conducted using r version 3.4.1 (see table 2 for full r package). base r was used for our statistical analysis. other r packages utilized in the project are listed in the table below. r package name version ggplot2 3.0.0 tibble 2.1.1 dplyr 0.7.5 tidyr 0.8.1 stringr 1.4.0 readr 1.1.1 readxl 1.3.1 table 2. r packages used in the analysis data preparation the following steps were taken in the data analysis: 1. content analysis into themes (see above) 2. normalize institution names. we received more than one response from a few institutions. for these, the responses were treated as separate responses that happened to have the same demographics. 3. for responses that included institution names, we added a total student population variable to the response using values derived from wikipedia and the carnegie classification of institutions of higher education. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 5 4. for variables we derived during the content analysis we coded them as 0 or 1 dummy variables, that is, 0 = not present, and 1 = present. coding them in this way allows us to bring them into a multiple linear regression model. 5. using an r script, we tested each response for the presence of the content analysis, 0 or 1. 6. plots were created using the r ggplot2 library. 7. linear regression models were conducted using the base r lm function. research dataset dataset, survey instrument, and r code are available through dryad at https://doi.org/10.5061/dryad.jwstqjq5d.22 survey respondents eighty-seven participants responded to one or more components of the survey. see table 3 for a breakdown of survey responses. survey question responses ux methods multiple choice: “please check the following ux methods that you personally use at least every year or two at your institution.” 81 ux methods free-text response: “would you like to add a comment clarifying the way you completed [the question related to ux methods]?” 20 ux maturity stage multiple choice: “which of the following [maturity stages] do you think properly describes the current ux status in your organization?” 79 ux maturity stage free-text response: “please explain why you selected that stage.” 54 table 3. survey responses. results our research results demonstrate that certain characteristics of a library organization are related to ux maturity. these characteristics include the type and extent of ux methods that are currently in use, as well as organizational factors such as leadership support, staffing, and collaboration. we further explicate below according to our two research questions. rq1: how mature is user experience practice within academic libraries? our survey also asked participants to identify which stage of the nielsen norman group maturity scale “properly describes the current ux status” in their organization. our findings indicate that most libraries are in a low-to-middle range of maturity, with more than 75% of respondents placing their organization at either stage 3, stage 4, or stage 5 (figure 1). https://doi.org/10.5061/dryad.jwstqjq5d information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 6 figure 1. histogram of responses by stage, showing that the majority of respondents placed their organization at either stage 3, stage 4, or stage 5. rq2: what factors influence ux maturity? overview of statistical analysis results we use linear regression for two different applications in this study (see appendix a for glossary of terms related to statistical analysis). the process of creating a statistical model allows us to see, with varying degrees of confidence, the impact of different variables on ux maturity stage. the results of the linear regression help us to tease out the variables with the most predictive value. using certain methods does not cause the library to be at a higher stage; rather, libraries that use certain methods tend to be at a higher stage, statistically. that is what is meant by “predictive” in this context. linear regression provides a ground truth in what we think we are seeing in survey responses: a useful general principle in science is that when you don’t know the true form of a relationship, start with something simple. a linear equation is perhaps the simplest way to describe a relationship between two or more variables and still get reasonably accurate predictions.23 the other reason we are using the linear regression output is to inform a possible future version of a ux maturity survey instrument, one more finely tuned to libraries than the nielsen instrument alone that we used in this iteration.24 we feel that our use of multiple linear regression is appropriate and helpful given the exploratory nature of our study. the complete output is available at https://doi.org/10.5061/dryad.jwstqjq5d. size of institution we used the institution’s student population, the number of full-time enrolled students, as our proxy for the size of the library. our assumption being, larger enrollment generally means larger https://doi.org/10.5061/dryad.jwstqjq5d information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 7 number of library staff. there are different ways ux maturity level could be compared with student enrollment; because the range in our sample is very wide, from 1,098 to 200,000 students across the sample of institutions, we attempted to control for the vast differences in size between the smallest and largest by sorting, from smallest to largest, 1 to 69 (the total number of cases in our dataset with both a stage and population defined), then assigning rank to the institution as an additional demographic variable. we then created a simple linear regression model comparing maturity stage as a function of ranked size. the null hypothesis is that there is no relationship between ranked size of institution and stage. stage is the response variable and ranked size of the institution is the explanatory variable. the adjusted r-squared relationship is 0.027. this means that only about 3% of the variance is accounted for by the ranked size of the institution. the probability, or “p-value,” of getting our observed result if the null hypothesis is true for this relationship is 0.095 (almost 10%). this exceeds the standard .05 confidence level commonly used in statistical analysis. therefore the size of the institution is not a reliable predictor of ux maturity level in our sample, a counterintuitive finding. the full statistical summary is available in the appendix. methods currently in use by academic libraries our next rq2 finding relates to the type and extent of ux methods that are currently in use in academic libraries. our survey asked participants to select which ux methods “you personally use at least every year or two at your institution.” user surveys, usability testing, and user interviews stand out as the most commonly used. figure 2 shows response counts for all of the methods in the survey. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 8 figure 2. number of respondents that selected each method in the survey, showing the type and extent of ux methods currently in use in academic libraries. we then examined the number of methods in use per institution compared to the reported maturity stage (figure 3). the number of methods used per institution illustrates a trend: more methods used at an institution generally means the institution is at a higher stag e of maturity. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 9 figure 3. the number of methods used per institution, illustrating that more methods currently in use at an institution generally indicates a higher level of maturity. another way of representing the same two variables (reported number of methods and maturity stage) is with a scatterplot and statistical test (figure 4). in this simple linear regression model we have two variables: the response variable is stage and the explanatory variable is number of ux methods used in the past two years. in plotting these two variables on a chart, we can draw a line that minimizes the distance between the line and all of the points on the plot. like the chart above, the linear relationship between total methods and stage is clearly visible. the total number of methods practiced accounts for about 18% of the variance when predicting the correct maturity stage. (recall from our discussion about ranked size of institution that rank accounts for less than 3% of the variation, and is not even statistically significant.) in this case, the p-value is far below the 0.05 threshold, meaning the likelihood that we are seeing a relationship by random chance is very low. therefore total number of methods is predictive of stage. generally, the more methods respondents chose, the higher the maturity stage. we can see from this data that the number of methods used is more predictive of maturity stage than institution size. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 10 figure 4. maturity stage compared against total number of methods used, showing the positive relationship between number of ux methods used and ux maturity stage. for a more granular view, figure 5 shows the relation of specific ux methods used in different ux research phases (as categorized in the survey question, with methods organized by discovery, exploration, listening, and testing) to reported maturity stage. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 11 figure 5. showing the relation of specific ux methods to reported maturity stage. factors that influence ux methods: recency, formality, regularity we then applied content analysis to the free-text questions of our survey. following the question that asked participants to select among 20 different ux methods that “you personally use at least every year or two at your institution,” the free-text question asked, “would you like to add a comment clarifying the way you completed [this question]?” each of the 20 free-text responses to this question was counted and categorized as a “meaning unit.” themes were extracted from the free-text survey responses. we identified 3 themes across 20 meaning units: formality, regularity, and recency (see table 4). question would you like to add a comment clarifying the way you completed [this question related to ux methods]? thematic analysis theme

qualitative questions and thematic analysis for ux methods responses (n = 20). factors that influence ux maturity: leadership support, collaboration, ux lead, ux group, growth, and resources we also

free-text responses to this question was counted and categorized as a “meaning unit.” themes were extracted from the free-text survey responses. we identified 7 themes across 54 meaning units:

the coded thematic responses (figure 6). figure 6. coded responses versus selected stage (0 indicates no comment related to that theme), showing that a lack of leadership support is often cited as a reason for not advancing past stage 3; the presence of dedicated staff in the form of a ux lead or a ux group is often cited as a reason for reaching stage 5. full ux maturity model: ux maturity as a function of ux methods in building a full model for the purposes of quantitative data analysis, we are attempting to predict the maturity stage based on the many different variables that appear in our dataset. this statistical exercise is a heuristic tool that can help us understand the survey responses and to draw results from the dataset that reveal key characteristics of ux maturity in libraries. we approached building a full model using a modified backward stepwise approach. with this approach, we begin with the full range of variables and work backward step by step to focus only on those variables that combine to form a model that makes the best predictions about the response variable—the ux maturity stage—for each case. through this process, those variables that are less predictive are removed from the model one by one until we can settle on a model that explains the most variance.25 the modified backward stepwise “step” function used to create our model required 18 iterations before settling on the best version. using adjusted r-squared as our metric, our full model accounts for 62% of the variance for this dataset. adjusted r-square is an appropriate measure because it allows us to include many variables but also includes a penalty for including too many variables (as a penalty, the adjusted r-square value will decrease). with this model, we can make reasonable estimates of the maturity stage that a survey respondent selected by knowing which methods they use combined with the coded explanation the respondent provided via the free-text survey questions. the coded responses (see table 4 and table 5) provided measurable insights into information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 15 the organizational context of our respondents’ institutions, and this allows us to analyze and predict their respective maturity levels. with this additional information, we have a model that represents the multiple dimensions available in the dataset (see appendix b for additional data analysis). in table 6, we show the relationship between specific ux methods and the ux maturity stages. we see here that journey mapping, for example, is a highly influential factor for ux maturity. variable estimated influence on maturity stage p-value (significance) journey maps

advancing maturity. similarly, we see that a lack of “leadership support” has a strong negative effect on maturity. information technology and libraries march 2020 user experience methods and maturity

stage, in descending order of influence on maturity stage. a statistical example case: estimating ux maturity to help the reader understand the statistical summary provided by our model, we take a close look at one case drawn from one actual survey participant. in this example case, the respondent’s institution is a four-year, large university. the intercept for this multiple regression model happens to be 4.1119. intercept in a multiple regression model represents the mean response (stage) when all the predictors are all zero.26 it is a baseline. our example institution has practiced the following methods, with their respective influence on ux maturity included in parentheses: • user interviews (+ 0.9521) • usability testing (+ 0.7984) • benchmark testing (+ 0.7124) • usability bug review (+ 0.2692) • field studies (1.3346) • prototype testing (0.8454) • user surveys (0.3204) additionally, this institution has the following organizational characteristics, with their respective influence on ux maturity included in parentheses: • leadership support: yes (0.6842) information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 17 • resources: no (0.2192) by adding these numbers together with the starting point (4.111), we can calculate that the predicted stage for this institution is 3.44. actual stage selected by survey respondent: 3 residual -0.44 the model predicts a stage of 3.440 for this large, four-year university library. the model’s predicted value for this library is 0.440 greater than the stage selected by this survey respondent. the leftover part, or error, is the residual. the attentive reader might at this point ask why the variable called leadership support: yes has a negative estimate, 0.6842. that certainly is counterintuitive. other evidence and our own interpretation lead us to expect that leadership support: yes should have a positive effect on the maturity. in this particular case, the negative estimate has a high p-value (0.177) and is thus unreliable and not significant to the model. part of the unreliability stems from the relatively small number of institutions (n = 9) that were coded as leadership support: yes. in contrast, responses that were coded as leadership support: no (n = 23) produced an even lower negative estimate of -0.9911, with a very reliable and highly significant p-value of 0.009. this shows us that when leadership support is lacking, maturity reliably suffers. we discuss this and other organizational characteristics in more detail below. discussion in interpreting our results, we have identified four key areas that we wish to emphasize: the significance of leadership support, the importance of organization-wide collaboration, the role of applied ux methods, and the emerging theory and practice of ux and design in libraries. leadership support and strategic alignment a major theme evident in the results relates to leadership support and strategic alignment. as expressed by the survey respondents, leadership support is viewed as the degree to which ux work is seen, understood by, and supported by library leadership and organizational strategic planning. in particular, a lack of support and visioning from leadership exerts negative pressure on ux maturity. on the other hand, when ux is coordinated with leadership vision and situated into strategic planning, ux maturity was rated more highly. from a leadership perspective, ux maturity relies on an allocated budget and designated staff to move beyond an ad hoc approach and reach higher levels on the maturity scale. one might expect that the larger an institution, the more advanced the ux maturity stage. however, based on our data analysis, size of institution is not a significant factor in ux maturity. therefore the resources provided to library ux activities may not be about how large institutions are, but rather if leadership acknowledge the importance of ux and provide official, particularly financial, support. organizational collaboration another major theme was collaboration—the degree to which ux research is collaboratively shared by individuals and departments throughout the library. higher levels of ux maturity are driven by a widespread understanding of ux within an organization, with user research data information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 18 integrated into decision-making across multiple touchpoints. conversely, a lack of collaboration was a factor that hindered maturity. many respondents shared similar experiences, telling us that other staff or departments within the organization are not ready to embrace the potential of ux data, methods, and insights. we recognize that cultivating ux is an organic process that can result in uneven growth of ux within an organization. some units may be ready to move further and faster while others may hesitate to contribute or collaborate. not every department will immediately see the relevance or value of ux work for their area. accounting or human resources, for example, might consider ux as beyond the scope of their practice. thinking inclusively and holistically from the perspective of user-centered service design, however, opens up new connections between ux and the work of all departments across the organization. ux can help center those users—even internal users—who interact with service points such as accounting or human resources in ways that can improve the service experience for all involved. applied ux methods across the 20 methods that we included in the survey, our results indicate that the application of different ux methods varies widely in type and extent. many methods are in use to varying degrees. as the methods relate to maturity, we find that a greater number of methods in use during the previous two years was indicative of a higher maturity rating. in short, more methods lead to more maturity. the five most common methods included usability testing, user surveys, user interviews, accessibility evaluation, and field studies. these methods are similar in their ease of implementation and their wide representation in the library literature, and due to their commonness, they are not strongly indicative of ux maturity, high or low. the five least common methods included journey maps, benchmark testing, design review, faq review, and diary/camera studies. in this grouping we see a set of ux methods that are not as well known or widely discussed, but which can paint a more complete picture of the user experience. journey mapping in particular was strongly and positively influential on ux maturity in our statistical model. this result does not necessarily indicate that a library can boost ux maturity simply by creating a journey map. rather, we interpret this to indicate that the method itself is reflective of a coordinated ux effort in the institution. journey mapping aims to obtain a high-level overview of a user’s interactions with every touch point to accomplish a task. as such, the successful implementation of a journey map relies on cross-functional and cross-departmental input and interpretation. this result calls for greater collaboration toward greater ux maturity. ux as an emerging practice within libraries many respondents focused on the newness or the maturity of their library’s ux practice, and most responses connected a low methods usage to the newness of the practice. in these responses, we see that ux in libraries is still a new field, and the practice is emerging with variations across institutions in terms of methods and maturity. we note that institutional size was not a factor that influenced maturity—some smaller institutions reported mature ux practice while some larger institutions reported lower ux maturity. in this result, we see that the amount of possible resources matters less than the intentional application of those resources in support of ux work. as institutions begin to see the value of ux and dedicate increasingly more resources relative to their budgets, ux maturity increases. our survey respondents shared a variety of experiences along this journey toward maturity. many told us “i’m new here” and that their library doesn’t fully understand ux and isn’t yet ready to include ux research in decision-making or strategic planning, or that the institution doesn’t have a plan yet for how to integrate the ux librarian into library operations. still others reported that librarians in other units or library administrators are information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 19 not required or encouraged to consult with the ux librarian or integrate ux research. in this way, many libraries continue a more traditional model of decision-making that does not regularly apply intentional methods to account for the voices of users. on the upper end of the maturity scale, on the other hand, we see a wide adoption of ux as a legitimate area of work varies across units and within leadership groups. in this way, some libraries have demonstrated more responsiveness to ux and have more successfully integrated ux practices into strategic and operational workflows. through the survey responses, we see a threestep progression that marks the emergence of ux as a trusted and legitimate methodology for understanding user experiences and designing library services: recency, formality, and regularity (table 4). in the earlier stages of maturity, survey respondents emphasize the newness or recency of a group or person assigned to conduct ux work. from there, a ux practice emerges as increasingly more formal as more ux methods are introduced more often into different contexts. finally, as a library reaches ux maturity, we see a frequent application of a wide variety of ux methods in all corners of the library and with many stakeholders, along with organizational decision-making that regularly includes ux research data. a ux maturity scale for libraries to help in understanding of the ux maturity scale and the characteristics related to each of its stages, we have adapted the nielsen norman ux maturity scale for a library context. table 8 shows a set of organizational characteristics that correspond to the eight stages of ux maturity. the indicators in table 8 are presented as an approximate guideline for understanding and diagnosing ux maturity. stage key indicators stage 1–2 apathy or hostility to ux practice; lack of resources and staff for ux stage 3 ad hoc ux practices within the organization; ux is practiced, but unofficially and without dedicated resources or staff; leadership does not fully understand or support ux stage 4 leadership beginning to understand and support ux; dedicated ux budget; ux is assigned fully or partly to a permanent position stage 5 the ux lead or ux group collaborates with units across the organization and contributes ux data meaningfully to organizational and strategic decision-making stage 6 ux research data is regularly included in projects and decision-making; a wide variety of methods are practiced regularly by multiple departments stage 7–8 ux is practiced throughout the organization; decisions are made and resources are allocated only with ux insights as a guide table 8. key indicators for ux maturity in academic libraries. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 20 this scale reflects the research presented in this paper while building on related models and prior research (more granularity is available in stages 2–6 because we received more survey responses representing those stages). we note that our research is consonant with prior work in this area. priestner includes a greater focus on library users (in contrast to a focus on library staff) as a key driver of library ux maturity.27 macdonald reports that ux work is defined by applied methods, in particular, qualitative research.28 sharon describes a ux maturity model based on two primary factors: the presence of ux researchers on staff and whether the organization actually listens to and responds to ux research.29 finally, sheldon-hess bases library ux maturity on the extent of applied ux methods and the level of user-centeredness present in an organization, as indicated by degree to which staff consider user perspectives in internal communications and decision making.30 taken together, we see common strands that can help illuminate the key factors of ux maturity in libraries: applied methods, leadership support in the form of resources and strategic alignment, organizational collaboration, and decision-making that includes ux research. strategies for climbing the maturity scale: toward a more user-centered library our results reveal a few key barriers and boosts to higher maturity, and one key point of stagnation. across the maturity scale, important factors that positively influence maturity involve leadership support and resource allocation toward ux in the form of personnel and infrastructure such as physical space, materials, strategic direction, and a working budget. notably, respondents in our survey reported being stuck at stage 3 due to a lack of leadership support. for instance, when resource-related comments appeared, we primarily heard about a lack of resources, which impaired maturity. participants reported a mixture of personnel in support of ux work. some libraries have a staff member dedicated to ux but lack a committee structure to support and advocate for the work. other libraries do not have dedicated ux staff but had formed committee infrastructure to collaboratively move ux forward. participants who lacked either a ux group or a ux lead reported lower levels of maturity and were particularly stagnated at stage 3 (see figure 5 above). alternatively, libraries are boosted to stage 5 with the presence of a fully empowered ux lead who has the support of a ux group or committee that can network throughout the organization and drive collaboration and cross-functional implementation of ux methods and research data. we found that respondents from libraries that possessed both a dedicated ux staff and a ux group tended to place themselves higher on the maturity scale. for those who reside at stage 5, having a ux group or a ux lead are the two main themes present in the survey. to move forward to stage 5, a library needs to organize a ux group with an appointed lead to coordinate ux practice widely throughout the organization, including in library spaces, web presence, learning services, and digital initiatives. a systematic and cooperative ux approach planned by an official ux group and led by a designated ux lead is the key indicator of stage 5. the support for the group and its lead needs to come rom not only leadership, but also colleagues throughout the library, which relates to the two major themes of leadership support and organizational collaboration. stage 7–8 is achievable only with significant investment in ux. given parent entity pressures, existing hierarchies, and prevailing non-user-centered cultures, libraries face a formidable set of challenges on the road to becoming user-centered organizations.31 this road is somewhat illuminated by the small number of survey respondents that marked themselves at a stage 7 or 8. highlights from their responses are instructive. one respondent told us, information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 21 we have multiple teams in the library to help with service design, conducting and gathering user research, and helping library staff think more about the user in their everyday work. we also have a couple special interest groups (sigs) dedicated to user research, ux, and assessment. we also have multiple departments within the library with ux expertise. from this response, we can see the key characteristics of ux maturity: leadership support up the line along with wide-spread collaboration throughout the organization. staff infrastructures including multiple ux-oriented committees help drive and coordinate ux work. this respondent also reported the recent hiring of an assessment librarian situated in the library’s administration department who will help coordinate ux work throughout the organization. these elements work together to meaningfully integrate user perspectives into both digital and physical spaces and in multiple units. moreover, this respondent marked 19 out of 20 ux methods currently in use (all but diary/camera studies), thus reinforcing the symbiotic relationship between ux maturity and ux methods: the variety of methods in use are a signal of maturity, and correspondingly, a greater maturity allows the space and resources for the application of more and different methods. another survey respondent at stage 7 remarked the following, my workplace has been very supportive in addressing ux issues both in digital and physical spaces. since being hired, i have created workflows that incorporate data that we gather from users. if there isn’t data gathered in a certain area, we usually find a way to update workflows so that we can get that data. almost every project that i have worked on digitally and in the physical spaces at the library has been the result of ux/ui data that has been gathered from our users. the elevated level of maturity at this library is especially reflected through the practice of “almost every project” being driven by user data. a truly user-centered library indeed integrates user data across all projects and advocates for the user at every opportunity. this respondent also marked a high variety of methods currently being practiced: 17 out of a possible 20 (methods not in use include diary/camera studies, user stories, and competitive analysis), further underscoring the two-way connection between methods and maturity. in further considering the upper reaches of maturity, we are inspired by an emerging theory of design-oriented librarianship that signals a professional paradigm shift such that ux could become recognized as a fundamental component of library research, education, and practice. 32 by investing more in ux methods, practices, and principles, libraries can achieve greater value and empowerment for our communities by designing more user-centered services and tools.33 ultimately, achieving stage 7–8 will result from deeply integrating user-centeredness across all operational phases, strategic planning, and decision-making of a library organization. limitations we note a few limitations of our study. first, the ux stages used in the survey were defined by jakob nielson in 2006 for corporate application, so it is perhaps a bit dated. further, the main goal of our statistical analysis is to develop a model that can accurately predict the ux maturity of a information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 22 library based on the ux methods employed at the institution combined with organizational characteristics. allison outlines three broad categories of error in regression analysis: measurement error: very few variables can be measured with perfect accuracy, especially in the social sciences. sampling error: in many cases, our data are only a sample from a larger population, and the sample will never be exactly like the population. uncontrolled variation: [age and schooling] are surely not the only variables that affect a person’s income, and these uncontrolled variables may “disturb” the relationship.34 in terms of measurement error, survey respondents may have bias when self-reporting maturity stage due to social pressures to produce desirable responses, meaning people tend to respond to self-report items in a manner that makes themselves look good.35 the resulting measurement error takes the form of over-reporting “desirable behavior” or under-reporting “undesirable behavior.” this is evident in some responses for ux maturity stages. for example, one respondent chose stage 5—“managed usability”—but the comment described a slightly different picture: i think we are still floundering between “dedicated ux budget” and “managed usability.” . . . we are at the stage where people know they should consult with us, but either they don’t or they do but don’t really hear the results, they are using us to confirm what they want to hear. in terms of sampling error, self-selection bias is a factor: our respondents might not be representative of the full population of ux librarians. we also did not make all of our questions mandatory, and as a result were not able to make use of all possible data within the scope of our survey. in terms of uncontrolled variation, our survey and statistical model does not fully account for all variables that influence ux maturity in libraries; for example, we included a limited list of ux methods, and we did not include questions that inquired specifically into the presence of a ux lead or ux group. future directions we see at least three paths forward for future research related to ux methods and maturity. first, librarianship would benefit from a ux maturity scale created specifically with and for our field’s theoreticians and practitioners. we propose one such scale above, but our scale has not undergone further testing, research, or validation. we note especially the library ux maturity scales of sheldon-hess and macdonald, which could be further synthesized or built upon.36 second, a selfassessment tool for diagnosing ux maturity could be developed based on a validated maturity scale. and third, the theory advanced by clarke that librarianship can be usefully conceived of and practiced as a design discipline warrants further critical attention, especially as it relates to the application of ux methods and the development of ux maturity.37 conclusion we applied a mixed-methods approach that involved content analysis and statistical analysis to a profession-wide survey. our research data and analysis demonstrate the type and extent of ux methods currently in use by academic libraries. the five most common methods are usability information technology and libraries march 2020 user experience methods and maturity in academic libraries | young, chao, and chandler 23 testing, user surveys, user interviews, accessibility evaluation, and field studies. the five least common methods are journey maps, benchmark testing, design review, faq review, and diary/camera studies. furthermore, we identify the organizational characteristics that help or hinder the development of ux maturity. ux maturity in libraries is related to four key factors: the number of ux methods currently in use; the level of support from leadership in the form of strategic alignment, budget, and personnel; the extent of collaboration throughout the organization; and the degree to which organizational decisions are influenced by ux research. when one or more of these four connected factors advances, so too does ux maturity. we close by emphasizing three key factors for reaching higher levels of ux maturity. first, we encourage library leadership to see the value of ux and support its practice through strategic alignment and resource allocation. second, we encourage libraries to commit to integrating ux principles and practices across all units, especially into leadership groups and through organization-wide collaboration and workflows. third, ux methods should be reinforced and amplified with personnel, such as a standing ux group and a dedicated ux lead that can help direct ux work and enhance ux maturity. libraries have the promise and potential to more deeply practice ux. doing so can allow libraries to more deeply connect with users and reach higher levels of ux maturity, with the ultimate result of delivering tools and services that further empower our user communities. information technology and libraries march 2020 user experience methods and maturity in academic libraries | young,

sample surely “over-fits” the dataset, that is, the model is unlikely to predict as accurately if applied to a different dataset. the model will undergo further refinement in the future. 25 we made a conscious choice to leave in some variables in this model that are statistically insignificant. we did so because it might be too early to fully dismiss these elements as unimportant; it could be that our sample was too small to really be certain. furthermore, our primary emphasis is in creating a model that does a good job of accurately predicting stage based on an array of different characteristics. removing all the nonsignificant variables in this model would actually lower the prediction accuracy. adjusted r-squared accounts for additional variables. 26 for more description of

2019 14 julia bauder (bauderj@grinnell.edu) is associate professor and social studies and data services librarian, grinnell college. abstract an intriguing new opportunity for research into the nineteenth-century history of print culture, libraries, and local communities is performing full-text analyses on the corpus of books held by a specific library or group of libraries. creating corpora using books that are known to have been owned by a given library at a given point in time is potentially feasible because digitized records of the books in several hundred nineteenth-century library collections are available in the form of scanned book catalogs: a book or pamphlet listing all of the books available in a particular library. however, there are two potential problems with using those book catalogs to create corpora. first, it is not clear whether most or all of the books that were in these collections have been digitized. second, the prospect of identifying the digital representations of the books listed in the catalogs is daunting, given the diversity of cataloging practices at the time. this article will report on progress towards developing an automated method to match entries in early nineteenth-century book catalogs with digitized versions of those books, and will also provide estimates of the fractions of the library holdings that have been digitized and made available in the google books/hathitrust corpus. introduction digital libraries such as google books and hathitrust have created tantalizing opportunities for research into the history of american culture: automated analyses of the entire corpus of books published at a given point in time. the attraction of this prospect is most clearly demonstrated by the avalanche of papers written using the google books ngram data, which provides counts over time of the words and phrases used in the works that make up the google books corpus. as soon as this data became available in 2009, it was used to make arguments about social, linguistic, and other changes over time as reflected in changes in the words used in print.1 however, for nearly as long, other researchers have been cautioning that the google books corpus is not a representative sample of publishing output, let alone of what the public at large was actually reading in a given year, and that its unrepresentativeness makes it dangerous to draw sweeping conclusion s from this data.2 one potentially feasible solution to the problem of unrepresentativeness in the google books corpus would be to use corpora based on the holdings of a specific library or a group of libraries. using library holdings to form corpora helps to remedy some known issues with using the google books corpus as an indicator of social change, such as the fact that many books did not become mailto:bauderj@grinnell.edu hathitrust as a data source | bauder 15 https://doi.org/10.6017/ital.v38i4.11251 popular and/or widely available until well after their official publication date, and that some prolific authors who contributed hundreds of thousands of words to the google books corpus were never as widely purchased and read as authors who wrote a single, short, best-selling work.3 although using books held by a set of libraries at a given time as the corpus has its own problems of unrepresentativeness—particularly, for long-established libraries, the fact that the books on the shelf at a given time represent not only works of interest to current users but also those of interest to users from decades past—triangulating this data with that provided by the google books ngram data would at least give some sense of whether and where these different corpora disagree.4 creating corpora using books that are known to have been owned by a given library at a given point in time is potentially feasible because digitized records of the books in several hundred nineteenth-century library collections are available in the form of scanned book catalogs: a book or pamphlet listing all of the books available in a particular library. however, there are two potential problems with using those book catalogs to create corpora. first, it is not clear whether most or all of the books that were in these collections have been digitized, incorporated into google books and hathitrust, and hence made available for ngram analyses. second, the prospect of identifying the digital representations of the books listed in the catalogs is daunting, as both widely agreed-upon cataloging standards and universal identifiers were not adopted until late in the nineteenth century. this article will report on progress towards developing a fully-automated method to match entries in early nineteenth-century book catalogs with digitized versions of those books, and will also provide estimates of the fractions of the library holdings that have been digitized and made available in the google books/hathitrust corpus. methods practical considerations dictated using data from hathitrust rather than from google books for this research. the hathitrust corpus, although not perfectly coextensive with the google books corpus, has very substantial overlap with it. the hathitrust digital archive was founded in 2008, when a group of large academic libraries formed a collaboration to archive and disseminate their digitized books. the vast majority of those digitized books—around 95 percent, as of mid-2017— had originally been scanned as part of the google books project; the agreements that google books entered into with the libraries typically stipulated that google had to provide the library with a digital copy of each book scanned from that library. 5 it was necessary to use hathitrust rather than google books as the comparison corpus because the metadata for the titles in hathitrust is readily available in ways that the google books metadata is not, including as bulk marc-data downloads. the libraries included in this analysis are social libraries, which were a type of quasi-public library that predated the now-standard, tax-supported public library in the united states. these libraries were privately owned and operated, but were open to some large portion of the population of a particular area who were willing and able to pay a fee or buy a share to belong to the library. although the presence or absence of a book in social library collections is not a perfect indicator of the book’s popularity—most social libraries pointedly refused to purchase the “trashy” but widely read sensational fiction of the day—it is a defensible proxy (although with some caveats, as noted above) for the popularity of the “serious” literature and nonfiction works that made up the bulk of these libraries’ collections. information technology and libraries | december 2019 16 roughly one hundred social library book catalogs published between 1800 and 1860 can be found in hathitrust.6 for the purposes of the present study, attention was focused on the thirteen library catalogs from ten different american libraries that were published between 1776 and 1825. (a list of these catalogs can be found in appendix a.) these catalogs were chosen because they are likely to present the worst-case scenario in terms of both of the challenges mentioned above: the highest percentage of rare and extremely old books, which google’s partner libraries would have been least likely to permit to be scanned by google, and, presumably, the most primitive and eclectic cataloging practices. to the extent that it was possible to do so, this analysis focused on book-length monographs. when serials or pamphlets were listed in a separate section of the catalog, those catalog pages were excluded from the process by which entries were extracted from the catalogs and parsed into csv files. serials present particularly intractable matching problems: not only are the original catalogs often unclear about which specific volumes were held, but also hathitrust’s marc data does not always clearly indicate which volumes are available in hathitrust either. pamphlets have limited coverage in hathitrust. the selected catalogs were downloaded from hathitrust as pdfs, and the pdftotext software was used to extract the ocr data from the relevant pages of the scans as hocr (a file format for ocr that includes information about where each word is located on the page in addition to the words themselves). 7 then cleaning scripts were created that parsed the hocr data into csv files for analysis, with one catalog entry per line of the csv file.8 given the widely varied cataloging practices of the early nineteenth century, several different cleaning scripts were written, each tailored to a particular catalog format. for example, many of the catalogs had entries that spanned multiple lines (see figures 1 and 2), so the scripts for those catalogs had to be able to identify when each new entry started. many catalogs had extraneous information, such as the name of the donor of the book or the size of the book, that had to be filtered out (see figure 1; f, q, o, and d refer to the size of the book: folio, quarto, octavo, or duodecimo). in addition, various forms of dittoes were frequently used in these catalogs (see figures 1, 2, and 3), so one of the tasks for the cleaning scripts was to identify the dittoes and replace them with the correct words from the previous entry. figure 1. library company of philadelphia, a catalogue of the books belonging to the library company of philadelphia: to which is prefixed, a short account of the institution, with the charter, laws, and regulations (philadelphia, pa: printed by bartram & reynolds, 1807), 5. hathitrust as a data source | bauder 17 https://doi.org/10.6017/ital.v38i4.11251 figure 2. library company of baltimore, a catalogue of the books, &c. belonging to the library company of baltimore: to which are prefixed the act for the incorporation of the company, their constitution, their by-laws, and an alphabetical list of the members (baltimore, md: printed by eades and leakin, 1809), 46. figure 3. washington library company, catalogue of books in the washington library (washington, dc: printed by anderson and meehan, 1822), 17. unfortunately, the horizontal-line dittoes seen in figures 1 and 2—a type of ditto which is used in seven of the thirteen catalogs—are represented inconsistently or not at all in the hocr, so they cannot reliably be used to identify places where words need to be carried down from the previous entry. for the catalog of the library of company of philadelphia, from which figure 1 was taken, the numbers after the horizontal-line dittoes (which identify the books’ locations on the shelves) can be used to distinguish between a line that is indented because it is a continuation of the entry above and a line that is indented but is the start of a new entry. in theory, a cleaning script for the catalog of the library company of baltimore (figure 2) could use a similar process to identify the last line of an entry by watching for the right-justified count of volumes at the end of each entry. information technology and libraries | december 2019 18 when a right-justified digit was encountered, the script could then carry down the first word from that entry if the first word in the next entry was indented. however, these isolated digits were also not handled well by the ocring process: many do not appear in the hocr file at all, and those that do are as likely to be ocred as a colon, an exclamation point, a capital i, etc., as they are to be a digit. hence, the three catalogs of the library company of baltimore, which use this format and have this ocr issue, were not analyzed for this project. table 1. results of verification library date founded if known, or inc. if not known9 date catalog printed number of spreadsheet entries number of entries handverified handverified entries that cannot be positively identified handverified, positively identifiable entries that are not in hathitrust positively identifiable entries successfully matched when work was in hathitrust library company of philadelphia 1731 1807 7619 128 0% 16.9% 79.8% horsham library company 1808 1810 143 143 28.4% 5.1% 79.8% salem (ma) athenaeum inc. 1810 1811 1585 130 0.8% 11.3% 72.3% new york society library 1754 1813 4522 135 5.7% 17.9% 76.1% providence library company 1753 1818 688 688 17.1% 9.4% 87.2% apprentices’ library (new york, ny)10 1820 1820 1811 124 34.4% 15.0% 69.7% washington (dc) library company inc. 1814 1822 900 124 12.9% 3.2% 83.7% boston library inc. 1794 1824 2273 138 4.1% 11.1% 82.5% mercantile library (new york, ny) 1820 1825 1386 138 0% 11.3% 86.0% hathitrust as a data source | bauder 19 https://doi.org/10.6017/ital.v38i4.11251 the catalogs of the other nine libraries could all be parsed with an acceptable success rate and, with one exception, were included. the exception was the salem athenaeum’s 1818 catalog, which was identical in format and nearly identical in content to the athenaeum’s 1811 catalog. given the overwhelming similarity it was decided to include only one of the catalogs; given that the goal of this analysis was to try to use the worst-case-scenario catalogs, the older of the two catalogs was chosen for inclusion. once the catalogs were parsed into csv files, they were run through another script that attempted to match each entry in the catalog against metadata from hathitrust. in february 2019, marc records containing metadata for 2,824,875 public-domain titles in hathitrust were downloaded from hathitrust via their oai feed and ingested into a local apache solr index for searching and matching, using code from the solrmarc and vufind projects.11 because of ocr errors in the catalog files and mistakes in the original catalogs, many of the words in the entries have one or more character-level errors. therefore, solr’s fuzzy searching option was used, which allows words to match as long as the levenshtein distance between them is two or less. (the levenshtein distance is the number of edits, such as changing one letter to another or adding or deleting a letter, it would take to turn one word into the other.) no attempt was made to match specific editions; as can be seen from the excerpts in figures 2 and 3, many of the catalogs do not contain sufficient detail to do so, even if it was desirable. the goal was merely to determine whether the text of that work, from any edition, was contained in the hathitrust corpus. once the catalogs had been checked against hathitrust, a sample of the entries was hand-verified. for the two smallest catalogs, the horsham library company and the library company of providence, all entries were hand-verified. for the other catalogs, a random sample of approximately 130 items (+/10) was selected. microsoft excel’s random-number generator was used to assign each line in the csv file a number between 0 and 1, and then the lowest 1.5 percent to 12.5 percent (depending on the number of items in the catalog) were examined. results percentage of works included in hathitrust a minimum of four of the books in every catalog examined was missing from hathitrust. as can be seen in table 1, the fraction of books from the hand-verified sample that was missing from hathitrust ranged from 3.2 percent for the washington library company to just shy of 18 percent for the new york society library. the library company of philadelphia, at 16.9 percent missing, had the second-highest missing number. it is not surprising that these two libraries, as two of the oldest and most venerable libraries in the united states at the time, owned the most books that are not represented in hathitrust, as both have a high percentage of very old and rare works. however, not all of the books from these collections that are not represented in hathitrust fall into that category. only six of the twenty missing works from the library company of philadelphia sample, and no more than eight of twenty-two from the new york society library, were published before 1700, for example.12 percentage of works that cannot be positively identified as can be seen in figures 1 through 3, some catalogs provided relatively full titles (figures 1 and 2), while others described the works in only two or three words each (figure 3). as might be expected, it is much easier to positively identify the works when fuller titles are provided, although two or three words proved to be enough to identify the work unambiguously the information technology and libraries | december 2019 20 majority of the time. (all of the titles shown in figure 3 can be positively identified, for example.) in the samples taken from the nine catalogs, the percentage of titles that were unidentifiably ambiguous ranged from 0 percent (library company of philadelphia, mercantile library of new york) to more than one in four (apprentices’ library of new york, 34.4 percent; horsham library company, 27.9 percent). the apprentices’ library of new york and the horsham library company were particularly problematic because they frequently omitted the name of the author, in addition to greatly compressing the title; without an author name, titles such as modern geography (apprentices’ library) and history of rome (horsham library company) present far too many potential matches. however, even including the author’s name does not make all greatly compressed entries identifiable. one particularly egregious example comes from the library company of providence’s 1818 catalog, which contains an entry reading “bell’s inquiry.” the list of candidates for this work includes a practical inquiry into the authority, nature, and design of the lord’s supper, by william bell; an inquiry into the causes which produce, and the means of preventing diseases among british officers, soldiers, and others in the west indies, by john bell; and inquiry into the policy and justice of the prohibition of the use of grain in distilleries, by archibald bell. figure 4. new york society library, a catalogue of the books belonging to the new-york society library (new york: printed by c. s. van winkle, 1813), 139. success rates for the parsing and matching scripts when there was a single, identifiable work that matched the catalog entry, and that work was in hathitrust, the matching scripts identified it at least 70 percent of the time for every individual catalog. unsurprisingly, catalogs such as those of the horsham library company and the apprentices’ library of new york that had entries that were difficult to positively identify were also more difficult for the script to properly match, although the matching script still succeeded between roughly 70 and 80 percent of the time. hathitrust as a data source | bauder 21 https://doi.org/10.6017/ital.v38i4.11251 for two other libraries with below-average matching results (the library company of philadelphia and the new york society library), many of the matching problems were caused by issues with the scanned catalogs that the data-cleaning scripts did not handle well. the new york society library catalog listed out the contents of multivolume sets in a way that was difficult for the cleaning script to identify and remove (see figure 4); instead, it was common for each volume of the set to end up with its own entry in the dataset. since the hathitrust records generally do not list out the contents of each volume, it was very rare for the cleaning script to correctly match a set based on an entry for one volume in the set. twenty-seven percent (six out of 22) missed matches from that sample failed because of this table-of-contents issue. for the library company of philadelphia, the problem lies with a quirk in the hocr where the character heights for many of the horizontal-line dittoes are extremely high—around twenty pixels, when the text around those dittoes is typically around ten pixels high. it appears as if the ocr program may have treated each horizontal-line ditto as an em dash and assigned it a height that would be proportional for an em dash of that length. these extra-tall line heights for the first “word” on the line cause issues with the algorithm that processes the text line-by-line, causing some entries to be inappropriately divided across two entries in the data spreadsheets. unsurprisingly, the matching script had difficulty correctly identifying the correct work in hathitrust when it was trying to match based on only half of the book’s title. conclusions although not a complete success, the results of this study provide hope that it might be possible to create full-text corpora based on the works in individual libraries with minimal manual labor, with a few caveats. the first caveat is that the digitized catalogs of those libraries must meet certain specifications: 1) the catalog is formatted, and has been ocred, in such a way that it is consistently possible to parse the catalog line-by-line and to identify algorithmically where each entry starts and ends. 2) the catalog provides at least the authors’ last names, if not their full names, plus a more-orless complete and accurate transcription of the title proper. 3) either the catalog contains minimal extraneous information (such as tables of contents or donors’ names), or the extraneous information is consistently formatted in a way that it can be algorithmically identified and removed. the second caveat is that even if all of these conditions are met, the full-text corpora that can be created will probably still be missing some small percentage of the books available in that library. one potential direction for future research could be more closely examining the books that are absent from hathitrust to see if there are any commonalities among them that might bias research done using these corpora, or if the missing works can safely be treated as random omissions. on the other hand, as was noted above, the catalogs used in this study represent a likely worst-case scenario for being able to positively identify the works listed in the catalogs and for those works being present in hathitrust. another promising avenue for future research would be to repeat this analysis on catalogs from the mid-to-late nineteenth century to see if the works in those catalogs are in fact more likely to exist in the hathitrust corpus. information technology and libraries | december 2019 22 appendix a: american library catalogs from 1776 to 1825 included in hathitrust boston library,

library collections became larger and more dynamic, making book catalogs much more difficult and expensive to compile and to keep up to date. by the end of the nineteenth century, book catalogs had largely been replaced by the card catalog system that remained in use through most of the twentieth century. although card catalogs were far superior for their primary purposes—maintaining an inventory of books presently owned by the library and allowing library users to locate the books that they wanted—they leave no permanent record of the books listed in the catalog at any particular point in time. 7 information about pdftotext can be found at https://manpages.debian.org/testing/popplerutils/pdftotext.1.en.html. http://hdl.handle.net/2027/hvd.32044080252174

disseminated via grant-funded digitization projects at the university of nevada, las vegas libraries special collections and archives. the six competencies are project planning, grant writing, project management, metadata, digital capture, and digital asset management. the authors will introduce each competency, discuss why it is important, and describe how it was developed during the course of the grant project, as well as how it was taught in a workshop environment. the differences in competency development for three different stakeholder groups will be examined: early career grant staff gaining on-the-job experience; experienced digital collections librarians experimenting and innovating; and a statewide audience of cultural heritage professionals attending grant-sponsored workshops. introduction digitization of cultural heritage resources is commonly viewed as an important and necessary task for libraries, archives, and museums. there are many reasons for engaging in digitization projects and creating digital collections, including providing increased access to unique collections, preserving fragile records, raising the global profile of the institution, meeting user demand, and supporting the teaching, learning, and research needs of host institutions. in addition, there is an expectation among the public that research resources are digitized and available online. from the perspective of librarians and archivists, digitization of special collections and archives materials involves more than just reformatting analog materials into a digital format (this article uses the term “digitization” to refer to the entire lifecycle of digitization projects involving special collections and archives materials, from planning to preservation). materials must be selected and prepared, the digital surrogates must be described and preserved, and access must be provided to the appropriate audiences. digitization work is often project-based, since each set of materials to be digitized may require different equipment, specifications, approaches, or workflows. digitization projects and workflows can be a solo affair, a temporary project team, or a permanent functional area complete with staff specializing in activities such as project management, grantwriting, web development, or metadata. staff learning needs will significantly vary depending on organizational characteristics, assigned roles, project specifications, and motivation of individuals. overall, the libraries’ and archives’ profession-wide approach to teaching and developing digitization competencies is somewhat haphazard. there are many methods to learn about digitization, including self-study of published resources, online tutorials and resources, conference presentations, workshops, continuing education courses, and masters in library and information mailto:gayle.ohara@wsu.edu mailto:emily.lapworth@unlv.edu mailto:cory.lampert@unlv.edu information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 2 science (mlis) program classes.1 in many graduate school programs there has been a move toward integrating digital library theory and practice, but courses are necessarily broad in nature, and not every student will be required or have the opportunity to complete a practicum or internship while studying. this can make it difficult for new librarians to identify which skills are most in demand and which type of self-study is most useful for the job market. identifying key competencies, and how to acquire them, may be helpful in supporting new librarians as th ey make the jump from graduate education to their first professional position, but it is not a challenge limited to newer professionals. even seasoned librarians and archivists, with practical experience in their portfolio, may find that their local experience does not translate to different organizations, is too broad for a particular project, or is not deep enough for them to lead the initiation of a new digitization program. the digital collections department at the university of nevada, las vegas (unlv) has a decadelong record of hiring early career librarians for grant-funded projects, providing them with opportunities to develop digitization competencies on the job. from 2017 to 2019, unlv’s digital collections department completed two grant-funded digitization projects that specifically set out goals to contribute to competency development for multiple stakeholders. early career project managers learned, practiced, and refined skills; the department experimented and innovated its own workflows; and the project team held two workshops to contribute to the development of digitization competencies throughout the state. the six main competencies that were developed during the grant projects are project planning, grant writing, project management, metadata, digital capture, and digital asset management. the authors, who were members of the grant project teams, will discuss the six competencies in this article. using the grant projects as a case study, they will describe each competency and share how it was used and developed within the project team via on-the-job learning, and within the state via the statewide workshops. literature review the idea of professional competencies for librarians and archivists is well-established and documented in academic literature, and defined competencies are recognized as valuable tools for education, recruitment, professional development, and evaluation. drawing from organizational project management literature, daniel, oliver, and jamieson define competency as the ability to apply combined knowledge, skills, and abilities in service of a measurable and observable goal. 2 in the united states, the american library association (ala) defines “core competencies of librarianship” and “competencies for special collections professionals.”3 the competency framework of the archives & records association of the united kingdom and ireland (ara) describes five levels of experience: novice, beginner, competent, proficient, and expert/authoritative.4 ara’s recognition of the varying dimensions of competency is a helpful guide, and aligns with the reality of different levels of expertise. however, the competencies identified by ala, ara, and other similar professional organizations are necessarily broad; competencies for specific library roles are harder to generalize and define. in order to identify the knowledge, skills, and abilities required of “digital librarians,” researchers such as choi and rasmussen analyzed job announcements and surveyed practitioners.5 job announcement analysis shows that there is no single definition of a digital librarian; instead digital librarian positions consist of many varied roles and responsibilities in almost infinite combinations. the competencies discussed in this article (project planning, grant writing, project management, metadata, digital capture, and digital asset management) were locally important to information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 3 unlv’s digitization projects, but they also align with the competencies identified in previous research. in their study of projects undertaken in the national digital stewardship residency program (ndsr), blumenthal et al. found that project management skills and technical skills (including metadata, workflow enhancement/development, digital asset management, and digitization) were important.6 the level of required technical competency tended to vary by project but workflow enhancement stood out as a universally important skill. a 2019 analysis of the latest career trends for information professionals by san jose state university’s (sjsu) ischool noted that there is increasing demand for project management skills across all career types. 7 this usually encompasses the ability to organize complex tasks and collaborate with other departments or institutions in service of a shared goal. sjsu also cited “new technologies” as a necessary skill. however, they specified that this refers to “all iterations relating to interest in, familiarity with, or experience with new and emerging technologies” (emphasis in the original). in choi and rasmussen’s article analyzing job ads, the authors note that many of the frequently stated job requirements tend to be vaguely described or cover broad areas, including current trends in digital libraries, competency on general technological knowledge, and the current state of information technology as three most frequently mentioned competencies. 8 digital asset management, digital scanning, digital preservation, and metadata were some of the specific technical skills desired, as well as project management, planning, and organization. research shows that the more generic the competencies, the more broadly applicable they are; but specific competencies depend on the local environment, the role of the position, and the variables of the project or responsibilities. the wide range of competencies required by the digital library field paired with the specificity of local implementation requires new librarians and archivists to seek out learning opportunities that target both theory and practice. in fact, one of the most important aspects of practical experience is the benefit gained by experiencing the concepts in real-world situations that require decision-making, iteration, and sometimes even failure. the education field points to the kolb model of experiential learning, a cycle that is composed of four elements: concrete experience, reflective observation, abstract conceptualization, and active experimentation. 9 these elements mirror the process of learning observed in the grant case studies. new project staff are often trained to do tasks, then reflect upon what went well or was challenging. then permanent staff in leadership roles encourage and facilitate discussions in abstract concepts such as the philosophy behind an organization’s decision to prioritize efficiency or the concepts of creating authentic digital surrogates. while it may not happen in every project, within both grant cases, the final phase of the learning cycle was also reached as project staff and permanent employees worked together to move practice forward through testing, experimentation with new methods, and ultimately innovation of new models for digital library practices in the area of large-scale digitization. kolb’s model can be useful throughout the library and archives field, as shown in the following example. the federal agencies digital guidelines initiative (fadgi) started in 2007 as a collaboration of federal agencies seeking to articulate common sustainable practices and guidelines for digitized and born-digital cultural heritage resources. the fadgi website is a treasure trove of approved and recommended guidelines covering still image digitization, embedding metadata, project planning for digitization activities, and more.10 it essentially provides step-by-step guides for all aspects of digitization and is a tool that those interested or actively involved in digitization should be familiar with and consult on a regular basis. however, information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 4 fadgi technical standards are relatively prescriptive, so organizations often have to decide how to implement them within their local environments, taking into consideration a wide range of variables. if every new digitization project manager conscientiously implemented the fadgi standards without associated institutional context, they could be investing their organization in long-term cost commitments that cannot be sustained over time or that do not meet the project goals. this scenario points to the need for hands-on experience and learning as outlined in the kolb model. the digitization project manager may want to revisit the goals of the project (access vs. preservation, or both) and resource allocations (storage capacity, software and hardware specifications, staff time and expertise), and then pilot a subset of materials by capturing with the fadgi standard and calculating the storage sizes of the files and any associated workflows for long-term management. through this small experiential exercise, much information can be gained, reflected upon, and then used to conceptualize how to proceed. most of the tasks associated with digital library projects demand increasing competency over time to progress from enacting the technical standard in an organizational context, to revising it across projects or local environments, to educating others about the role of the standard, or to, at the highest levels of competency actively participate in the creation or revision of the standard itself as it changes over time. the ability to not only implement but also refine and even innovate comes from a process of mastery of the competency in question. experiential learning is an important method for developing and refining competencies from a novice to more expert level, but not all librarians and archivists have the opportunity to learn from more experienced colleagues on the job. matusiak and hu emphasize the importance but also the inconsistency of integrating experiential learning into mlis programs.11 for those who do not gain practical experience in library school or on the job, workshops are an additional learning opportunity that can help professionals bridge the gap from written resources to local implementation. the illinois digitization institute is one example described in detail by maroso in 2005.12 digital directions is a conference that presents the “fundamentals of creating and managing digital collections” in two days.13 other available workshops focus more closely on different aspects of digitization, such as metadata or preservation, or training for specific equipment via a vendor. in the following examination of unlv’s digitization grant projects and workshops, the authors address six competencies that were either employed or developed by staff or have been identified in existing literature. these competencies may be viewed as critical building blocks for digitization projects and the authors address how they were developed to different levels of expertise and using different methods, experiential learning, and workshops. overview of grant projects unlv’s digital collections completed two grant projects with the main goals of: (1) the large-scale digitization of archival collections, (2) the development of large-scale digitization models and workflows that could be reused, and (3) statewide workshops to share those models and workflows with other libraries and archives institutions. both projects were funded by library services & technology act (lsta) grants administered by the nevada state library and archives. the first project, “raising the curtain: large-scale digitization models for nevada cultural heritage,” digitized mainly visual materials on the topic of las vegas entertainment, while the second project, “building the pipelines: large-scale digitization models for nevada cultural heritage,” digitized mostly text documents about water issues in southern nevada. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 5 digital collections hired two types of temporary project-specific staff for the two digitization grants: project managers and student assistants. the project manager for each grant coordinated the day-to-day activities, such as preparation of the materials, digital capture, quality control, metadata, and ingest into the digital collection management system, as well as helping to fine-tune workflow documentation. the student assistants contributed to digital capture, quality control, metadata creation, and upload to the digital collection management system. these grant projects are strong examples of experiential learning and competency development. two of the authors were principal investigators (pis) for both of the grants, and one author was the project manager for the second building the pipelines grant. at time of hire, the project manager for the second grant had experience working in special collections and archives but had not previously worked in a digital environment. one student assistant was hired for this project; she had already worked on the first large-scale digitization grant project in digital collections and was already familiar with the digitization workflow, as well as the hardware and software. employing a student who had already experienced the concrete tasks (phase 1, “concrete experience” in the kolb model) allowed her to help the new project staff as they cou ld together perform “reflective observation” (phase 2) and learn from their compiled shared experience. the project pis were intentional in designing opportunities for discussion. they regularly met with the student and project manager to help them understand what they were seeing and experiencing in the context of the organization's mission and the grant goals (kolb’s “abstract conceptualization”). the building the pipelines grant project facilitated each of them gaining more competency and moving to the next level while also helping the pis learn through experimenting with new approaches (the final phase of “active experimentation”). the same experiential learning model was also successfully used for the first raising the curtain grant project. as previously stated, conducting a day-long digitization workshop for nevada libraries and archives was a goal of both large-scale digitization grant projects undertaken by unlv digital collections. the nevada statewide large-scale digitization workshops, which were held towards the end of each grant period, were free for participants, and travel grants were available thanks to the grant funding. the workshops sought to provide an overview of large-scale digitization using unlv projects as examples, as well as to provide practical advice related to developing digitization competencies. the first workshop that unlv held in may 2018 consisted of presentations and discussions addressing the basics, methods, and challenges of large-scale digitization. the second workshop, held in may 2019, still shared what unlv learned about large-scale digitization during the grant project, but widened the scope to address multiple important digitization competencies, whether the project is large or small. competencies whether presented in a project-based learning environment, a one-day workshop, or in a selfstudy scenario, learners can benefit from a clear understanding of what is meant by competencies in each of the areas that make up a successful digitization project. below, the authors share the competencies most critical to success in the case study projects. these were also the competencies selected as priorities for the workshops. while expertise is not mandatory in all of the competencies in order to start a digitization project or apply for a grant, reflection and planning for each of these steps should be addressed prior to initiating any project. by identifying available resources (such as existing documentation, available staff with expertise to consult, or approval from a supervisor for a self-study plan) project managers can ensure that if there are any information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 6 competency gaps, they will learn the needed competencies to carry out the project. in addition, throughout the learning process, interpersonal skills such as proactive communication, adaptability to change, flexibility in evolving job scope, and cultivation of comfort with ambiguity are all qualities that are just as necessary as any technical skill in mastering competency in digitization. project planning this competency can be defined as the ability to create a shared and documented vision and plan so that specifications, expectations, roles, goals, and timelines are considered in advance and clear to everyone involved. planning for a digitization project is best approached holistically. the planning period is the time to consider all needed competencies and plan for their implementation. writing up a project plan is important, especially since digitization can involve many collaborators and stakeholders. even if one is working alone, there are so many components, steps, and details involved in digitization projects that it is important to plan ahead for them and to document everything. brainstorm and write down ideas and plans for the project, from the overall scope, goals, timelines, and roles, to the specific details of each component, including specifications and workflows for digital capture, metadata, access, preservation, assessment, and promotion (see appendix a, “an overview of planning and implementing digitization projects”). the plan should be communicated, remain flexible, and be updated (or better yet, versioned) to document changes implemented during the project. an important part of project planning is selecting materials for digitization. to develop competency in effectively selecting materials, a person should be familiar with the materials and the digitization process or collaborate closely with people who are. it is often not until one is in the weeds and discussing the nitty-gritty details of a project that the challenges and actual viability of digitizing specific materials become apparent. format is a huge factor in digitization, as is description, and understanding how materials will be used.14 digitizing a group of materials that can all be processed the same way is much easier than undertaking a project to digitize many different formats that require different digitization specifications, equipment, description, processing, etc. one must also take into account legal and ethical considerations. successful selection of materials takes all factors into account and targets materials that fit with the overall goals and vision of a specific project.15 in the case of unlv’s grant projects, the head of digital collections and the digital collections librarian identified the main goals, developed tentative workflows, and authored the grant applications as copis. the pis had multiple years of experience planning and completing digitization projects, which they drew upon to plan these projects. they both started off developing their digitization competencies by completing pilot projects, developing workflows and writing grants to fund smaller-scale, highly curated “boutique” projects. as they honed their skills and the department’s workflows over the years and the organization built the capacity and expertise to successfully scale up the rate of digitization, digital object production grew from one staff member using one scanner to digitize a couple hundred items in a year, to a robust department with a digitization lab that produces tens of thousands of digital surrogates per year. the pis documented the vision and goals of the projects in the grant applications, along with timelines, desired outcomes, the roles of the team members, and budgets. the grant application information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 7 provided a structure to help with the bigger picture of project planning, and the digital collections librarian also used a template to create detailed digitization plans for the collections. the template was developed locally based on past experience planning and implementing digitization projects (see appendix b for unlv’s “digitization plan template”). project planning was completed prior to the hire of the project managers and student assistants. the project managers and student assistants were responsible for enacting the project plans, and during the projects they were empowered to adapt and improve upon the plans. the modelling provided by the pis, coupled with the day-to-day experience of the project managers, led to the continuous improvement of and adaptation of workflows through experiential learning. the grant application and digitization plan, along with all of the prepared workflow documentation and tracking spreadsheets, provided a concrete example of how large digitization projects can successfully be planned. by implementing and refining the plans herself, the project manager gained direct experience and intimate knowledge of the plans, including what worked well and what did not. the project manager therefore developed competency in project planning to be able to create plans herself, and the pis further refined their own planning skills, allowing them to plan for even larger or more complex projects in the future. based on previous experience with projectbased learning, the pis had already established a level of expertise at roughly level 4 in the ara tiers. level 5 includes innovation, which was a target of the grant project as it required the pis not only to successfully map past experience to a new situation, but in cases where experiences did not map, gain new knowledge through experimentation. the project team included project planning as a topic of the statewide digitization workshops, sharing digitization plan templates, finalized workflows, and other planning resources that aided in the successful completion of the grant projects. building upon feedback from the first workshop in 2018, the second one addressed the ability to create a digitization project plan of any scale, recognizing that many nevada institutions do not have the ability to engage in large-scale projects. despite the emphasis on the foundational importance of project planning, most attendees noted that they do not currently create detailed digitization plans prior to starting a project. providing examples of plans, practical resources, sharing hands-on experiences, and welcoming discussion was helpful to participants, as indicated by feedback on the post-workshop survey. the workshop organizers scheduled time for participants to work on their own digitization plan, and also offered private consultations to help them, but many participants did not have a specific project in mind and did not seem ready to jump into the details of project planning during the workshop. overall, these teaching strategies helped participants gain a better idea about how to plan digitization projects, but they do not match the experience of creating or implementing a plan oneself. grant writing all projects begin with an idea, but only a small fraction of possible projects are acted upon. this is due primarily to a scarcity of resources. grant writing is not a necessary competency for all projects, but it is a valuable skill that can secure funding for projects that otherwise would not have been prioritized or possible. in its simplest form, a grant is a well-communicated idea with supporting rationale that effectively communicates why a project is a priority to undertake.16 grant applications are usually composed of a narrative section that covers the main goals, a budget with associated costs for the project, letters of support from partners, and details about the project team leading the work. even if a grant is not needed to undertake a project, the process of writing one often mirrors the very same decision-making that is necessary in the project planning information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 8 step. project planning is recommended for all digitization projects and it is nearly always required by external grant funders. grant writing can be undertaken alone, in a team, or (in larger institutions) as part of a research office or external funding program. in any case, it can be defined as the skill of writing text, calculating costs, and compiling relevant documentation to successfully propose projects for the award of external funding. competency in grant writing requires excellent communication skills, including the ability to craft persuasive arguments advocating for the project and the analytical ability to interpret instructions and guidelines to ensure the project is in compliance with the funder’s requirements. often, grant writing involves several people: disciplinary experts, collaborative partners, commercial vendors or contractors, technicians, and advisory boards. being able to facilitate discussions and coordinate actions is vital to wrangling the pieces of a large grant pre-award, as well as successful grant administration once funded. grants are competitive in nature, so creativity and originality in framing of a problem can mean the difference between a highly ranked grant and one that is passed over by reviewers. one method to obtain competency in grant writing is to read as many grant proposals as possible, specifically targeting those for similar projects.17 in addition, some funders look for a panel of grant reviewers and seeking out opportunities to participate in these processes is a valuable education. in the case of unlv digital collections and the pis, grant writing has been honed over time by some of the strategies mentioned above: reading other grant applications, serving on grant review panels, collaborating with other stakeholders, and communicating with the granting agency to understand criteria and solicit feedback. although the grant proposal was written and the grant was secured prior to the hire of the project managers, the project managers were able to develop a thorough understanding of the grant process. by successfully completing the grant projects, in addition to reviewing the grant proposals, contributing to quarterly reports, and discussing the projects with the pis and other stakeholders, the project managers gained valuable experience and understanding to inform their own future grant applications. given the scarcity of resources, the statewide digitization workshops made it a priority to address various aspects of locating grant opportunities, preparing to write proposals, seeking out collaborations to strengthen applications, and the mechanics and timelines to expect when applying for grants. one of the panel sessions in the workshops included a presentation by the state library’s grant administrator, who provided an overview of the state process and what the board looks for when reviewing project proposals. many participants found this particularly helpful because seeking out and applying for grants for digitization projects was not within their frame of reference, especially as many did not believe they had the requisite expertise in digitization. awareness of a need, gathering information, and analyzing examples are some of the first steps in developing a competency. the workshops helped attendees take these first steps of developing competency in grant writing and management but fell short of actually helping them to write their own grants. in this case, however, it was appropriate since the attendees did not have specific projects in mind and likely needed to spend more time in the first stages of competency development before jumping into implementation. workshops are most effective when the level of the content is appropriate to the level of expertise of the attendees. project management project management training is not often specifically emphasized in mlis programs. while there is literature on this topic, most people learn on the job.18 a successful project manager demonstrates information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 9 mastery of this competency by taking responsibility and assuming leadership of the project throughout the process, even if they are not intimately involved in the day-to-day tasks. they often are responsible for hiring and training project team members as well as communicating and responding to project team members and stakeholders. while they are tracking and analyzing progress using appropriate metrics, they are often the one raising a red flag if the project is experiencing delays or challenges. because they are responsible for ensuring the completion of the main goals of the project within the specified timeline, they often need to analyze bottlenecks and propose possible solutions in order to deliver high-quality results. ideally, they learn from their experiences and also help other team members and the organization learn from experience. a key role of the project manager is not only to deliver the outputs, but to assess and analyze, both during the project, in order to make improvements, and after, in order to inform future projects. therefore, investment in mentoring and supporting a project manager, whether a temporary or permanent staff member, can greatly influence how much learning takes place during the project and how that acquired knowledge is transferred to others. documentation is a key part of project management. this needs to happen at every interval of the project—while planning, during implementation, and at the conclusion.19 documenting concrete data including the time spent on specific activities helps to plan cost predictions for future projects, as well as to make recommendations regarding future staffing and equipment. mastering this competency involves planning, an eye for both details and the big picture, clarity, transparency, communication, and dedicated recordkeeping from the start of the project to the end. much like in project planning, the unlv pis had multiple years of experience stewarding projects from start to finish, which assisted them in on-the-job development of the project management competency. they were able to share with the project managers their accumulated years of learning experiences on both the projects, providing guidance on what to look for and how to comprehensively document the current digitization projects. this mentorship, combined with the experience of managing the day-to-day workings of the digitization projects, allowed the early career librarians to develop this competency. in addition, monthly project staff meetings, complemented by on the spot consultation when necessary, contributed to the ease of competency development. during the statewide digitization workshops, the project teams discussed digitization project management and shared strategies and tools such as using google sheets and trello to track workflows and progress. the teams also provided advice for aspects of project management such as managing student workers, troubleshooting equipment, transparent communication, and more. the project team chose to focus specifically on their own large-scale digitization experience because literature and resources about general and library project management are readily available. in addition, participants were encouraged to consider how their non-digitization experiences with project management could be translated to this kind of project as a way to encourage reflective learning based on their individual experience. metadata digitizing materials would not be a valuable endeavor without comparable investment in describing them with metadata that aids users in discovering and using the digital objects. developing a project plan that includes metadata approaches is essential in scoping project work and resources. metadata assignment and quality review is often a far more resource-intensive step information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 10 than the process of digital capture. metadata is one digitization competency that is robustly addressed in library school programs. standards are well documented and examples of digital library metadata are easily accessible online. the importance of metadata to the library and archives profession means that many professionals already have a foundational knowledge. what makes metadata a difficult competency to master is the level of detail and specificity it entails, which makes the step from theory to practice challenging. metadata competencies require an understanding of recognized standards, the ability to interpret and apply them, and an awareness of metadata mobility including: reusability, interoperability, and flexibility for migration or transfer.20 metadata-related skills require comfort moving along a wide spectrum of varied tasks, often toggling between awareness and understanding of high-level philosophical issues (such as inclusiveness of subject terms) and a laser-focused eye for detail to troubleshoot data issues (like correcting spreadsheets or code). metadata work traverses several phases of the digitization lifecycle: from initial preparation of collections, during capture, through the ingest into systems, and over the long-term to maintain and preserve the assets. metadata quality itself is difficult to quantify, making this a competency that can be tricky to evaluate. mastery can be indicated through the identification and study of appropriate standards, including compliance with any data reuse requirements, such as a regional digital library consortium, or metadata requirements to ensure compatibility with existing systems and data. in addition to selection of standards, or adherence to existing standards, metadata can be subjective and needs to be undertaken with attention to the level of specificity required for the project. completion of successful projects demonstrates efficient processing of records balanced with an appropriate level of metadata richness. documentation of metadata approach via a metadata application profile (map) as well as training materials and examples for metadata creators are also good indicators of metadata expertise. while technical skills are valuable for metadata competencies, communication and soft skills should not be underestimated as part of this skill set. often metadata competency is an area where collaboration is required. many libraries have catalogers, metadata librarians or aggregators that can advise and sometimes train or provide documentation for projects. before creating a new metadata approach from scratch, consultation can be a very effective way to gain greater competency. at unlv, the choice of an already processed collection eased the metadata choices for digitization. this meant there was already a certain amount of basic metadata regarding the collection; in addition, having the curator function as a subject expert engaged in prepping the collection enabled the project team to have a readymade list of prioritized subject terms, people, and corporate bodies available to input as each folder in the collection was digitized. the building the pipelines project manager had prior coursework in metadata, as well as experience assigning metadata in a previous internship. using the unlv’s metadata application profile as a guide and the existing metadata procedures established for the project, the project manager was able to hone a better understanding of metadata theory applied in practice, including how to best capture the “aboutness” of these particular digital objects. the project manager also observed the importance of consistency in applying metadata by performing quality control of the studentcreated metadata. a final contributing factor in developing competency in this area is that the team, consisting of the digital collections librarian, the project manager, and the student assistant, had many resources available as a team to solve problems. as previously mentioned, the team met information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 11 to review any project concerns and to pull in adjacent team members such as technical services staff, the metadata librarian, the curator, or even those with experience in programming and application development who could advise on how the metadata would appear in other systems, such as the one being developed for future digital collections. this larger group feedback was invaluable in the learning process and often touched on the more abstract concepts underpinning the tasks. at the statewide workshops, a metadata “bootcamp” was held in which staff addressed the types of metadata standards attendees were likely to encounter, the role of a metadata application profile, how to identify an existing map and apply it to your collection materials, as well the value of having a subject expert available for consultation. while reuse of existing description data (e.g. , finding aids or inventories) was an important topic for the first workshop, in response to feedback the second workshop’s metadata bootcamps focused more on concrete steps required to make digitized images searchable regardless of other workflows or systems that might be in use. again , this was an example of tailoring the content to the learning level of the audience. while all participants were familiar with metadata, many did not have experience using a map or taking interoperability into consideration. many recognized a need to devote more time to developing this competency, regardless of project. digital capture whether it is done in-house or outsourced to a vendor, competency in digital capture (digitization in the most specific sense) is key. this competency requires considering the materials to be digitized, how they will be displayed, and how long-term access will be provided to the digital objects. working in-house, technical mastery is not required, but it is necessary to have a solid idea of what hardware and software capabilities are, as well as who to consult should difficulties arise (and they will).21 mastery of this competency means having a vision for the ongoing presentation and use of the digitized material and outlining specifications to make that happen. documenting digitization specifications is useful not only for the project manager and for fu ture projects, but also as a training tool for students, interns, and volunteers. it can also be a source of important preservation and technical metadata ensuring files created today are sustainable into the future. in addition, a robust quality control workflow should be in place prior to uploading digital objects for display and use. a key component of digital capture is efficiently preparing the selected materials. at unlv, experience has taught the digital collections department that digitization is most successful when using materials that have already been physically processed (surveyed and arranged) and for which an inventory (finding aid) has been created. digitization of archival materials can quickly become complicated because they are often not physically uniform or consistent, and sometimes they are grouped together for digitization into complex/compound/aggregate digital objects. well thought-out workflows for naming and tracking individual files can make the digital capture process smoother, especially when files are related (such as the front and back of a photo, or pages of a scrapbook). this item-level documentation is critical to managing the large volume of files created in digital capture. any conservation or preservation concerns of the physical materials should also be addressed prior to capture. additional consultation may be required if unforeseen complications or problems arise during digital capture; item-level review may not be possible for all materials during the planning stage. for instance, there may need to be an alternate workflow for items that contain personally identifiable information or which are too fragile to undergo scanning or capture. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 12 there are a number of options for capturing images to create digital surrogates, including digital camera systems and a variety of scanners. depending upon the method of capture, additional software may be needed to edit, output, and ingest the images into a digital management system. for a text-heavy collection, software for optical character recognition (ocr) makes the items fulltext searchable. for audiovisual materials, digital capture is even more complex. the local hardware, software, and procedures for capture all may require an investment in hands-on time learning and testing procedures. the repetitive nature of capturing items may also require some investigation of ergonomics or more human-friendly configurations of these variables. at unlv, step-by-step documentation for using the various hardware and software is key to developing staff competencies. such documentation includes screenshots of steps in the process to contribute to comprehensive understanding and correct implementation of the workflow. projectbased staff also make suggestions, as they move through projects, to improve current workflows. the clear documentation, repetition of tasks, access to workflows of prior digitization projects, consultation with experienced staff, and review of available resources (such as the previously mentioned fadgi website) all contributed to competency development for the project managers. although the pis have years of experience digitizing, it is a detailed process that can be forgotten without use and practice, and it is a competency that must be continually cultivated because of changing technology. if it is decided to outsource digital capture, there are a number of factors to take into account in order to find the right vendor. issues to consider include cost, company stability, prior clients and completed projects, timelines, where the work is performed, and preferred communication methods. requesting a quote for services can be a good way to gain visibility into vendor communications, flexibility, and workflows, and will be essential if the project funds are administered in conjunction with any state or organizational purchasing rules or guidelines. although it can be time-consuming, it is vital for the research and legwork to take place prior to starting the project (see the “project planning” section). in outsourcing, confidence in the digital capture partner is key. mastery of this aspect of digitization means a comprehensive, transparent agreement, a regular flow of communication, and comfort in letting go of control over a major part of the project. resources provided by the northeast document conservation center (nedcc) and the sustainable heritage network help to consider the pros and cons of both in-house and outsourced digital capture.22 project management skills can also be very useful as working with a vendor shifts the needed competency from digital capture to more of a project management focus. unlv often employs vendors for the more challenging formats mentioned, such as oversized materials like maps and architectural drawings, and for materials like newspapers that require specialized zoning in the metadata to retrieve articles. working with a vendor can be an informative experience, teaching communication skills, negotiation of contracts, building appropriate timelines, and quality reviewing deliverables. some granting agencies cover a limited timeframe and outsourcing digital capture can free up an organization’s time to do more librarycentric work like metadata or archival processing. for the building the pipelines project, most of the material in the selected collections was flat printed material that was not oversized or in challenging formats such as film/transparent material, newspapers, or media (audio/video). this led to a high comfort level for in-house digital capture as there were established procedures for the archival collection. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 13 at the statewide workshops, participants attended a digital capture session where they were presented with digital capture workflows and information about unlv’s decision-making regarding digitization equipment, outsourcing vendors, and technical standards, and then they went into the digitization lab to observe the equipment in action. the digital capture bootcamp was facilitated by the head of digital collections, the student assistant, and the visual resources curator (who is a professional photographer). this unstructured session offered a place for attendees to preview equipment that might be suitable for their projects, get a sense of costs if they were looking to purchase equipment, and to observe the digital capture in a large-scale workflow (a specially designed rapid capture overhead camera system), a medium-scale workflow (with digital slr camera and copy stand), and a small-scale workflow (flatbed and map scanners). attendees were encouraged to match equipment to their project needs or identify if outsourcing was an appropriate approach for their collection. attendees were not able to use the equipment themselves or practice the digital capture workflows, but the small workshop format allowed them to view demonstrations in person, ask specific questions, and also see example workflows in action, which is a step above what online research or resources provide for competency development. digital asset management competency in digital asset management goes beyond identifying the storage capacity necessary for a project. digital asset management includes the storage, access, and preservation of digital files and their accompanying metadata. there are different ways to provide access to digital objects, some of the most popular being online content management systems like omeka or digital collection management systems like contentdm.23 as mentioned previously, metadata is important for staff and users to discover and locate digital objects. competency in digital asset management requires technical knowledge of how to securely and efficiently transfer digital files that are requested, or how to provide secure and user-friendly online access. it also requires planning to ensure that whichever approach taken is sustainable and can meet demand. good digital preservation means planning and implementing the necessary actions to ensure that digitized resources continue to be discoverable, accessible, and usable well into the future. in the case of digitized libraries and archives materials, this means that they must be well-documented and trustworthy. preserving digital materials includes maintaining multiple copies of files, capturing checksums to verify if the bits of a file have been corrupted over time, and in some cases, migrating file formats so that items can be viewed and used with future hardware and software. models for digital preservation include the open archival information system (oais) model and the national digital stewardship alliance (ndsa) levels of preservation.24 software and tools to aid in digital preservation tasks are available, as is training. however, digital preservation is still relatively new to many in the libraries and archives profession, although some individuals and institutions have developed very sophisticated and carefully considered programs and approaches. since digital preservation is based on technology, it will always be changing. one must not only learn and be able to implement the current standards and best practices of digital preservation, but also always keep up with changes. success in digital preservation requires ongoing effort and evaluation. successful digital preservation means that staff and users can find, understand, view, and use digital resources at any point in the future. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 14 for the grant project managers, this was the most challenging competency. while they were exposed to the complexities of digital preservation at unlv, this process was already wellestablished, having been developed over time by the pis and other library staff. the project managers essentially stewarded the newly digitized objects up to this point and then handed over the reins to the digital collections librarian. while they were free to ask questions and developed an understanding of the standards that contribute to long-term digital preservation, the project managers did not implement this particular workflow, nor did they contribute to adapting it. it is important to keep in mind that digital preservation is not an all or nothing proposition; small steps can be taken by libraries and archives professionals to address short-term digital preservation while gaining a better understanding of long-term solutions.25 given the complexity of this competency, it was difficult to train participants in the statewide digitization workshop setting. however, unlv’s digital collections staff emphasized the multiplicity of options available for libraries and archives with varying levels of resources and encouraged participants to be open to starting despite ambiguity about the ultimate long-term solution for their organization. digital collections staff also provided an overview of these options and shared the evolution of digital preservation strategies at unlv, including suggesting some first steps such as creating an inventory of digital assets and a digital preservation plan. developing expertise in this competency requires in-depth research, consultation, and analysis to customize plans for local circumstances. the statewide workshops provided only an hour-long introduction to the topic and a broad overview as an example. digital preservation is a topic that is well-addressed by other more intensive workshops though, such as the society of american archivists digital archives specialist courses and the powrr institute.26 summary of competency development: experiential learning versus workshops learning through experience for project teams unlv’s grant projects are examples of how specific time-bound projects and grant funding can be utilized to develop both individual and organizational competencies, and to share what is learned via workshops, aiding in the professional development of others. the early career project managers advanced the most in competency development because of the opportunity for focused training and experiential learning through practice. they progressively developed digitization competencies in a number of ways, including training from the pis, working with experienced student assistants and staff, reading locally created documentation, observing project activities and decision-making by the team, proposing solutions to challenges and testing them through trial and error, learning by doing tasks and suggesting small iterations to improve them, consulting the workflows from previous projects, and reviewing recommended resources such as the fadgi website. the project managers, though temporary employees, were treated with the same status as permanent staff and encouraged to attend meetings, ask questions, take risks, and experiment in a safe and controlled environment of learning. given the many multifaceted details and tasks that go into a digitization project from start to finish, it is unrealistic to expect staff to remember everything without engaging in the process themselves. training for the grant projects broke each project down into a series of discrete steps, including preparation, digital capture, quality review, ocr transcription, metadata creation and review, and upload into the digital asset management system. each task was reviewed and practiced in a linear manner. given the volume of materials, basic mastery and self-sufficiency for information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 15 the grant project staff were achieved fairly quickly. this allowed project staff to then identify areas for workflow improvements and test adjustments for increased efficiency. despite having just two dedicated staff, one of whom had no prior digitization experience, over 55,000 digital surrogates were created during the ten-month building the pipelines project, far exceeding the original goal of 10,000 images. in both grant projects the project managers were able to develop digitization competencies as a result of on-the-job experience, enriching their skill sets while also assisting unlv digital collections to refine workflows for large-scale digitization projects. this in turn strengthened competencies on the organizational level, and those of the pis. in the best-case scenario of this kind of project, temporary staff develop valuable digitization competencies via project-based work; however, that is not always the case, and temporary project-based positions can be very harmful to the personal and professional development of workers. when undertaking a project that uses temporary labor, the organization should plan for and prioritize equitable hiring practices, fair compensation and benefits, and a positive and productive experience for temporary staff.27 learning through experience for organizations grants are temporary in nature, so it is important that organizations who fund them and who receive funding think about the long-term implications of the temporary work. it is important for project staff to clearly document all of the details of the digitization approaches and workflows that worked successfully in the grant, as well as any problems that can be avoided. all the extra work of testing and refining new workflows completed by the project staff, can (and should) be adopted and integrated by permanent staff into the existing structure of the department or institution. one of the drawbacks for institutions undertaking grant-funded projects is that temporary staff leave and take their expertise with them. it is essential for permanent staff to not only teach, but also be open to and active in learning from the temporary staff during the project, even if the permanent staff are not doing the day-to-day work. building opportunities for information-sharing and knowledge transfer into a project plan vastly increases the value of the grant project funding. this organizational learning is a form of accountability to the funder ensuring that projects can be sustained and that lessons learned contribute to increased capacity in the funded organization and beyond. learning through workshops for professional development grant projects also pave the way to share lessons learned with colleagues via workshops or collaborative endeavors. as previously stated, conducting a day-long digitization workshop for nevada libraries and archives institutions was a goal of both large-scale digitization grant projects undertaken by unlv digital collections. besides the metropolitan areas surrounding las vegas and reno, much of nevada is rural and sparsely populated. these workshops provided a forum for people who might not usually come together to meet and talk about their work. many libraries and archives institutions in nevada are small and may have limited or no experience with digitization. the workshops sought to provide an overview of large-scale digitization using unlv projects as examples, as well as to provide practical advice related to developing digitization competencies. the first workshop at unlv, held in may 2018, consisted of presentations and discussions addressing the basics, methods, and challenges of large-scale digitization (see appendix c for the may 2018 agenda, “nevada statewide large-scale digitization symposium”). the grant team surveyed participants after the workshop and received mostly positive responses. sixteen out of information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 16 nineteen people who completed the survey said they learned something, thirteen said they were confident and likely to apply what they learned, and eleven people said that if there was a follow up workshop they would attend. the comments from the surveys showed that participants wanted more interactive activities, and many of them were not ready to implement large-scale digitization at their institutions—they wanted to learn more about the basics of digitization first. this feedback highlighted two challenges of workshop-based learning: the tendency toward passive delivery of large amounts of information and designing content for an audience with unknown or varying skill levels. the second workshop, held in may 2019, still shared what unlv learned about large-scale digitization during the grant project, but widened the scope to address multiple important digitization competencies, whether the project is largeor small-scale (see appendix d for the may 2019 agenda, “nevada statewide large-scale digitization symposium”). prior to the workshop, attendees were surveyed about their expertise level and topics of interest and were asked to review a project planning document with their local materials in mind. sessions were designed as bootcamps with more extensive documentation that could be used as a template for implementation at their home organization. participants were encouraged to ask questions and share their own experiences during the workshops and were given the option to sign up for a private consultation. the team endeavored across the workshop to allow for more interactive, hands-on learning. although unlv adjusted the second workshop based on the feedback from the first, teaching practical how-to skills that are broadly applicable in a one-day workshop is challenging. digitization is a complicated and technical undertaking that is most easily learned via hands-on experience, which is most effectively gained through repetition rather than a one-day workshop. there was not enough time or equipment for participants to actually practice parts of the digitization process themselves and so experiential learning was not always an option for every competency. also, if participants return to an organization with different equipment, hardware, and software, there are limits to hands-on training. another potentially problematic issue is staying up to date with the rapid technological changes that characterize digital collections. if a person gains a basic intellectual understanding of digitization via a workshop or other professional education opportunities, and then returns to their setting without starting a specific project in a timely manner, there is a risk that the knowledge they gained becomes outdated. despite the drawbacks of workshop-based learning, workshops are still valuable venues for colleagues to come together and learn from one another. they can also provide demonstrations or hands-on learning activities that help to bridge the gap from written theory to local implementation. conclusion online access to libraries and archives materials is expected and increasingly necessary in order for institutions and their collections to remain vital, useful, and relevant. ideally, digitization in libraries, archives, and museums would be a permanent functional area with specialized staff. however, many medium and smaller libraries and archives institutions do not have the capacity to sustain such an area. competencies in the areas of project planning and management, grant writing and administration, digital capture, metadata, and digital asset management are instrumental in order to complete a successful digitization project or institute a digitization program in any setting. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 17 despite the proliferation of professional workshops, online resources, literature, and conferences regarding digitization skills, it can be difficult to make time to study these materials and put such learning into practice in a way that builds to more sophisticated learning through experience. the diversity of collection materials to be digitized, the range of local circumstances, and the changing pace of technology prevent any profession-wide standardized approach to digitization education. instead, individuals, organizations, and the profession as a whole must strategically invest in the most effective and efficient methods and opportunities for developing digitization competencies. locally, unlv digital collections has found that experiential project-based learning is the most effective way to pilot new workflows and develop competencies. project-based experiences, if thoughtfully designed with an eye to mentoring and supporting temporary staff, provide an opportunity for individuals to develop and practice these competencies in a hands-on way that encourages deep learning. there is a unique place for small pilot projects, modest grant projects, or one-time experimental projects to create a space for this kind of learning in almost any organization. as capacity increases, digitization projects can also be designed to develop competencies at the staff functional group level, the organizational level, or the regional level. workshops in turn can be an opportunity for project teams or experienced individuals to share what they’ve learned and teach basic competencies to others. although not as comprehensive and effective as experiential learning, workshops can provide a solid introduction to digitization competencies, especially if interactive and hands-on learning methods are incorporated and there is a willingness for organizations to remain available for consultation or questions from attendees. workshops that have a preand post-session component can add continuity, and workshops that can be offered multiple times have the ability to evolve and scale. rotating instructors, incorporating hands-on sessions, and on-going mentoring are all ways to improve workshopbased learning. scaffolding these approaches and sharing what is learned individually or locally with others is a way to continue to develop the capacity of libraries and archives institutions to provide global online access to unique historical materials. although this approach is already widespread in the profession, it is important not to leave individuals or institutions with less resources behind. when planning new digitization projects or initiatives, institutions should consider adding and investing in new positions, partnerships, and regional collaborations and networks. when new permanent positions are not possible, temporary positions should be designed to be empowering and valuable for workers, rather than exploitative and harmful. in an age where technology is changing rapidly and is driven by large, well-resourced corporations, developing the profession’s competencies in digitization, keeping pace with digital technologies, and remaining relevant in the information environment depends on decentralized, peer-to-peer educational opportunities that use efficient and effective methods of teaching, such as interactive and hands -on learning. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 18 appendix a an overview of planning and implementing digitization projects created by emily lapworth for local use, march 8, 2018. shared at the statewide digitization workshops. these steps were written for large-scale digitization but can be applied to any size digitization project. 1) identify collections for digitization. a) brainstorm your goals for this project. think about what you will do with these digital surrogates, and who your audience is. b) criteria for selection of materials i) formats: start simple. if everything's the same, large-scale workflows are easier to apply. ultimately you will need to create different workflows for each format with differing requirements. for example, print photos are digitized differently than film negatives. text documents benefit from transcription using optical character recognition (ocr) software, while photos do not, and handwritten materials present additional discoverability challenges. when creating complex digital objects with different formats within them things can become even more complicated. ii) condition: fragile materials require extra handling time and possibly additional physical treatment prior to digitization. iii) existing arrangement and description: it is easiest if online access can directly mirror physical access, but the materials may need additional arrangement and description before digitization, depending on your goals. if the materials already have item or folder level description that is ideal. if there is any hierarchy in the existing description, especially inconsistent or complex hierarchy, consider how you will reuse that description for digital objects. iv) copyright: plan on providing public online access only if you own the copyright, have permission from the copyright holder, or if it is a strong case of fair use. c) see preparation step (below) to come up with some idea of how you will undertake this project. it will likely be modified during the actual preparation, but you need to have some idea of what you will do and how you will do it in order to gather support and resources. 2) assess the technical infrastructure needed to create, manage, provide access to, and preserve the digital files. a) estimate how much storage space you will need, and how much space will be needed for long-term digital preservation. b) make sure that your current digital preservation policies and workflows will be able to accommodate this project. adjust them if needed. c) identify what equipment and software will be needed and if you already have it, can acquire it, or can use someone else’s. d) assess if your existing workflows and systems for providing access to digital materials will be able to accommodate this project, and what changes you might need to make. e) technology could be a great area for collaboration! if you lack certain resources, explore opportunities to collaborate with other institutions. 3) coordinate with other stakeholders to verify choices and plans for digitization. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 19 a) find out what kind of support there is (financial, staffing, etc.) from management, administration, and the community. b) identify possible collaborators and discuss plans, make agreements, etc. c) decide who will manage and oversee the project and how different responsibilities will be distributed. d) identify and apply for grants if appropriate. 4) prepare collections for digitization. a) arrangement: assess how are the materials physically arranged and described, and if it will help or slow down your anticipated workflows. plan for and complete additional processing if needed. b) decide how you will display digitized materials. mirroring existing arrangement is the easiest, but you also have to consider the file formats you want to create. c) description: figure out how you can reuse existing description. plan metadata fields, vocabularies, prioritized subject terms and names. d) prepare preliminary metadata. reuse what you already have! e) prepare physical materials. verify that physical contents of the collection match existing description or inventory. remove staples, unbind, unsleeve, flatten, etc. identify and address any preservation or conservation issues. f) identify physical formats (this will help determine timeline and what equipment is needed). g) decide: outsource or in house? h) create and test workflows and procedures. i) create documentation for workflows and procedures (important for duration of project, for reusing for future projects, and also for future employees stewarding these digital assets to know what you did and how you did it). j) create and prepare systems, documents, or mechanisms to track work (it’s important to stay organized, especially when dealing with a large amount of materials or a team of workers). 5) digitize collections a) set up consistent file naming procedures and make sure they are followed. b) when dealing with mixed materials in house: depending on equipment and composition of materials, start with the easiest or what you have the most of, then take note of other formats (e.g., transparencies, oversize, etc.) that require different equipment or settings so you group them together to do later all at once. c) keep specifications simple if possible, especially if you have student workers doing the digitization. (for example, if you have complex digital objects with both text and photographic prints, and can digitize both materials on the same equipment without changing settings, do so. if you normally digitize text at 300 ppi but want photos at 600 ppi, rather than having the technician stop and change the settings, capture all at 600 ppi if you have the space.) d) auto-crop is a great tool if you have it but otherwise try to improve the efficiency of your processes with any tools at your disposal. sometimes this can be as simple as placing the item with the correct orientation to avoid the need to manually rotate later. e) file formats: archival images are generally tiffs. smaller derivative files may be necessary for access or to speed up ocr processes. sometimes it’s better to output them at the time of scanning than to batch process later. 6) process images information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 20 a) see above: try to improve your digitization workflows and procedures to shave time off of image processing. b) ocr: if you have textual materials ocr transcription makes them much more accessible with less manual work into creating detailed metadata. this is especially true for large aggregations of textual documents. resist the urge to have perfect ocr transcription. something is better than nothing, and when dealing with scale, you do not have the time to correct everything. here is also an opportunity for crowdsourcing, if you have the technical resources to set it up. c) ocr file output: depending on how you choose to display and make the digital surrogates available, you may need to output text files and/or pdf/as. 7) describe and provide access a) reuse description that already exists (e.g., from an inventory or a finding aid). if a finding aid exists, make sure you are using all available information and understand how description is inherited and can be reused. b) at the beginning of the project transform the metadata that already exists into a format you can use to describe the digital objects. you can add to this existing metadata throughout the workflow. c) at the beginning of the project identify preferred subject terms and important names to look out for and add to digital object metadata when appropriate. this is especially important when metadata is created by students or teams or anyone unfamiliar with the subject matter of the collection. it will help ensure consistency and make faceting better for users. d) explore how search engine optimization (seo) works for your public online access system. take that into consideration when creating metadata in order to optimize discovery of the materials. e) make it as easy as possible for users to identify the provenance of the digital object and to find other digital objects from the same collection. f) consider the links between the original collection description and the digital surrogates. consider adding digitization information or links to digital surrogates into finding aids and other records. consider also adding a link to the finding aid in the digital object metadata. consider using persistent identifiers, such as arks (archival resource keys), to d o this, instead of using regular urls. g) find out how your access system indexes full text transcripts and how it displays different file formats. consider if you are able/if you want to offer multiple file formats of a digital object. for example, a compound digital object that includes both text and images could be available as a collection of image files, a single pdf file, or both. identify what would be most useful to your users. h) don’t forget about structural, administrative, technical, and preservation metadata! 8) implement quality control procedures (qc) a) have a strategy (e.g., sampling), guidelines, and goals for qc. b) for staff performing quality control, identify the most important things to look for. c) decide how much time should be spent on qc. d) identify and acquire any automated tools that can be used. e) set up procedures or steps to follow when errors are found. 9) preserve digital assets a) you should have already planned how you will ensure access to and preservation of the digital files and metadata in the long term. best practice is to have policies in place information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 21 identifying what digital assets should be preserved and to what extent. identify applicable standards and best practices, implement software and technical solutions. b) set up workflows and procedures to ensure that the digital files receive appropriate ongoing digital preservation treatment. 10) publicize and promote a) work with administration, collaborators, and other stakeholders to publicize and promote the project. b) depending on your audience, social media, academic listservs, and professional organization publications can be other avenues to spread the word. c) set up harvesting with your regional digital library for inclusion in the digital public library of america. 11) assess a) web statistics can be used to track the use of online materials. see saa/acrl’s “standardized statistical measures and metrics for public services” section 8 “online interactions” for general information on what information to collect, and the digital libr ary federation’s “best practices for google analytics” for specific information on google analytics. if you are a contentdm user, see “google analytics in contentdm.”28 b) surveys, interviews, and focus groups are other methods that can be used to gather feedback. c) record and compile any oral or written feedback received from stakeholders and audiences. d) analyze feedback and use statistics to identify areas of success and areas for improvement. make improvements as necessary and incorporate findings into planning for future projects. information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 22 appendix b digitization plan template template created by emily lapworth for local use and shared at the statewide digitization workshop. project overview collection name(s): collection number(s): link to finding aid(s) or existing description(s): project staff: project supervisor: research value/audience: goals: available resources: staff, money, equipment, software, etc. additional resources needed: staff, training, money, equipment, software, etc. priority level: low, medium, high. why is this being digitized now? part of the regular workflow, part of a grant project, or specially requested? publicity and promotion plans: assessment plans: estimated time frame/due date: estimate how much time should be spent on the collection, or when it should be finished by. date completed/approximate hours spent: formats and quantity of items: e.g., seven boxes of photographic prints, three folders of flat text documents, two drawers of oversize materials, etc. existing arrangement & description: how the collection is currently arranged, what description is currently available? copyright: what is the copyright status of the materials and can you legally digitize and provide access to them? restricted or sensitive materials: e.g., skip over restricted folders, digitize restricted item notice, or physically cover pii (personally identifiable information, such as social security numbers) during digitization. preservation issues: any fragile or delicate materials that need extra attention? supply needs: e.g., envelopes needed for rehousing information technology and libraries december 2020 cultivating digitization competencies | o’hara, lapworth, and lambert 23 notes for future/follow-up: e.g., missing items, materials that should be restricted, recommend additional processing, rehousing, digitization, metadata enhancement, etc. preparation what will be digitized and what won’t be? e.g., series x will not be digitized at this time. it consists of audiovisual materials which would need to be outsourced. how will items be arranged and described online? how will identifiers/file names be assigned? e.g., each folder = a compound object, file titles from the finding aid will be used as titles for the digital objects what physical preparation must take place before digitization? e.g., remove all staples and fasteners digitization equipment/technical specs: • outsourcing or in-house equipment to be used • file types (e.g., tiffs) • file quality (e.g., 24-bit color, 600ppi) • file naming other specifications: • where will digital files be stored and preserved? • how will special physical formats be handled?
